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

    The Certificates will consist of one class of senior certificates designated
as  the  Class  A  Certificates  (the  "Senior  Certificates"),  one  class   of
subordinate   certificates  designated   as  the   Class  B   Certificates  (the
"Subordinate Certificates")  and one  class representing  the residual  interest
(the  "Class R  Certificates"). Only  the Class A  Certificates and  the Class B
Certificates  (collectively,  the  "Offered  Certificates")  are  being  offered
hereby.  The Class A Certificates and the  Class B Certificates will evidence in
the aggregate approximate initial [    ]% and [    ]% undivided interests in the
Contract   Pool,    respectively.   The    rights    of   the    holders    (the
"Certificateholders")  of the Class  B Certificates to  receive distributions of
principal and interest are  subordinated as described herein  to such rights  of
the Class A Certificateholders, and the rights of the Class R Certificateholders
to receive distributions of principal and interest are subordinated as described
herein to such rights of the Class B Certificateholders. See "Description of the
Certificates  -- Subordination" herein and "Credit and Liquidity Enhancement" in
the Prospectus.
 
    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  [           ], 199[  ].  The Offered  Certificates will  have  the
respective  [fixed] Pass-Through Rates specified  above. See "Description of the
Certificates" herein.
 
    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 Offered
Certificates will  represent  "regular interests"  in  the REMIC.  See  "Certain
Federal Income Tax Consequences" herein and in the Prospectus.
                            ------------------------
 
    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.
 
   
    This Prospectus Supplement does not  contain complete information about  the
offering of the Offered Certificates. Additional information is contained in the
Prospectus  and purchasers are urged to read both this Prospectus Supplement and

unless the  purchaser  has received  both  this Prospectus  Supplement  and  the

meanings ascribed to such terms in the Prospectus.
    
 
    UNTIL NINETY DAYS AFTER THE DATE OF THIS PROSPECTUS SUPPLEMENT, ALL  DEALERS
EFFECTING TRANSACTIONS IN THE OFFERED CERTIFICATES, WHETHER OR NOT PARTICIPATING
IN  THIS DISTRIBUTION,  MAY BE REQUIRED  TO DELIVER A  PROSPECTUS SUPPLEMENT AND

    IN CONNECTION WITH THIS OFFERING, THE UNDERWRITERS MAY OVER-ALLOT OR  EFFECT

                                        (iv)   to  the   Class  B   Certificateholders,  any
                                        remaining  Formula  Principal  Distribution   Amount
                                        after  distributions under  clause (ii)  above until
                                        the Class B Certificate  Balance (defined below)  is
                                        reduced to zero; and
                                        (v) to the Class R Certificateholders, any remaining
                                        Available Distribution Amount.
                                    As  to  any  Distribution Date,  the  "Class  A Interest
                                    Distribution Amount"  is equal  to the  sum of  (i)  one
                                    month's interest at the Class A Pass-Through Rate on the
                                    Class  A  Certificate  Balance and  (ii)  any previously
                                    undistributed shortfalls in interest due to the Class  A
                                    Certificateholders  in  respect  of  prior  Distribution
                                    Dates; the  "Class B  Interest Distribution  Amount"  is
                                    equal  to the  sum of  (i) one  month's interest  at the
                                    Class B  Pass-Through Rate  on the  Class B  Certificate
                                    Balance and (ii) any previously undistributed shortfalls
                                    in  interest due  to the  Class B  Certificateholders in
                                    respect of prior  Distribution Dates.  Any shortfall  in
                                    interest  due to Certificateholders  will, to the extent
                                    legally permissible, bear interest at the related  Class
                                    A or Class B Pass-Through Rate.
                                    The  "Formula Principal Distribution  Amount" in respect
                                    of a Distribution Date equals  the sum of (a) the  Total

                                    related  Collection  Period,  was purchased  by  Bank of
                                    America or BankAmerica Housing Services, as the case may
                                    be, on account  of certain  breaches of  representations
                                    and  warranties made by  it in the  Agreement, (iii) all

                                    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

                                    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 "Description of the Certificates -- Distri-

                                    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 "Class A Certificate Balance" as of any Distribution
                                    Date is the Initial Class A Certificate Balance less all
                                    amounts previously distributed to Class A
                                    Certificateholders on account of principal; the "Class B
                                    Certificate Balance" as of any Distribution Date is  the
                                    Initial  Class  B Certificate  Balance less  all amounts
                                    previously  distributed  to  holders  of  the  Class   B
                                    Certificates  on account of principal. In no event shall
                                    the aggregate distributions of principal to the  holders
                                    of  the  Class A  and  Class B  Certificates  exceed the
                                    Initial Class  A  Certificate Balance  and  the  Initial
                                    Class B Certificate Balance, respectively.

Subordination of the Class B
 Certificates.....................  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
                                    herein,  to such  rights of the  holders of  the Class A
                                    Certificates. This subordination is intended to  enhance
                                    the  likelihood of regular receipt by the holders of the
                                    Class A Certificates of the full amount of interest  and
                                    principal  distributable  thereon  and  to  afford  such
                                    holders  protection   against   losses   on   Liquidated
                                    Contracts.
                                    The  protection  afforded  to  the  holders  of  Class A
                                    Certificates by means of the subordination of the  Class
                                    B  Certificates will be  accomplished by the application
                                    of  the  Available  Distribution  Amount  in  the  order
                                    specified  under "Distributions"  above. Accordingly, in
                                    the event that the Available Distribution Amount on  any
                                    Distribution  Date  is  not  sufficient  to  permit  the
                                    distribution of the amount of interest and the specified
                                    portion of the Formula Principal Distribution Amount due
                                    to  the  holders  of  the  Class  A  Certificates,   the
                                    subordination  of the Class  B Certificates will protect
                                    the Class  A 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 holders of the
                                    Class   B   Certificates,   until   any   shortfall   in
                                    distributions to the holders of the Class A Certificates
                                    has  been satisfied, to the extent described herein. See
                                    "Description of the  Certificates -- Distributions"  and

Losses on Liquidated Contracts....  As described above, the  Total Regular Principal  Amount
                                    distributable to the holders of the Series 199[ ]-[    ]
                                    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 interest distributions due to the holders of the
                                    Series  199[  ]-[       ] Regular  Certificates  and the

                                    The effect of any losses on Liquidated Contracts  during
                                    a Collection Period in excess of the aggregate of Excess
                                    Interest  generally will be to reduce the Pool Scheduled
                                    Principal  Balance  below   the  aggregate   Certificate

                                    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
                                    Certificateholders and the Senior Certificateholders, in
                                    that order.
Monthly Advances..................  For  each  Distribution  Date,  the  Servicer  will   be

                                    change the lienholder specified therein to the  Trustee.
                                    In  some states,  in the absence  of such  a notation or
                                    amendment, the assignment to the Trustee of the security
                                    interest in the Manufactured Homes may not be  effective
                                    against   creditors  of  BankAmerica  Housing  Services.
                                    However, neither Seller will be obligated to  repurchase
                                    or  substitute  a Contract  solely on  the basis  of the

                                    members thereof. Certificates  representing the  Offered
                                    Certificates  will  be  issued in  definitive  form only
                                    under the  limited circumstances  described herein.  All

Federal Income Tax
 Consequences.....................  For  federal income  tax purposes,  an election  will be
                                    made to treat the Trust  Fund as a real estate  mortgage
                                    investment  conduit ("REMIC"). The Series 199[  ]-[    ]
                                    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 with payment terms  equivalent to the terms  of
                                    such  Certificates. The  Series 199[ ]-[      ] Residual
                                    Certificates will be treated as the "residual  interest"
                                    in the REMIC for federal income tax purposes. Holders of
                                    the Series 199[ ]-[    ] Regular Certificates that would
                                    otherwise   report  income   under  a   cash  method  of
                                    accounting will be required to include in income  inter-
                                    est  on the  Series 199[ ]-[      ] Regular Certificates
                                    (including original issue discount  ("OID"), if any)  in
                                    accordance with an accrual method of accounting.
                                    The  Offered Certificates, depending on their respective
                                    issue prices, may be issued with OID for federal  income
                                    tax purposes.
                                    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  Class A  Certificates
                                    may  be  purchased by  employee  benefit plans  that are

                                    Section 4975 of  the Internal Revenue  Code of 1986,  as
                                    amended  (the "Code")  should not  purchase or  hold the
                                    Class B Certificates as such actions may give rise to  a
                                    transaction  prohibited under  ERISA or  Section 4975 of
                                    the Code. See "ERISA  Considerations" herein and in  the

                                    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 [Class  A]

Rating............................  It is  a  condition  to  the  issuance  of  the  Offered
                                    Certificates  that  the  Class A  Certificates  be rated
                                    "[    ]"  and that  the Class  B Certificates  be  rated

                                    requested  ratings  on the  Offered Certificates  by any
                                    rating agency other than [            ]. 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

                                  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  either  Class  of  Offered
Certificates with liquidity of investment or that it will remain for the term of
such Class of Offered Certificates.
 
    2.   DISTRIBUTIONS OF  PRINCIPAL.   The yield  to maturity  on the  Class  B
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. [For any Distribution Date on which the Class A Certificate
Balance has  not been  reduced  to zero,  the  Class A  Certificateholders  will
receive  all payments of  principal that are  made on the  Contracts.] It is not
possible to predict the  timing of the occurrence  of the Distribution Date,  if
any,  on which the  Class A Certificate  Balance 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. Prepayment 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 nor BankAmerica Housing  Services
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 and  BankAmerica
Housing  Services, as the case may be, with  respect to the Contracts sold by it
in the  Contract Pool  and, in  the case  of 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 OR BANKAMERICA HOUSING
SERVICES, 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 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.   CLASS B  CERTIFICATES.  The  Class B 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 Certificates, thereby  limiting the  market for such
securities. See "Legal Investment" in the Prospectus.]
 
                               THE CONTRACT POOL
 
    Each Contract was purchased or originated by BankAmerica Housing Services or
SPFSC, in  each case  on  an individual  basis in  the  ordinary course  of  its
business.  A description  of BankAmerica  Housing Services'  and SPFSC'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, the  Sellers
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.  BankAmerica Housing Services, as  Servicer, will obtain and maintain
possession of all Contract documents.
 
                                      S-13
<PAGE>
    Approximately [    ]% of the Contracts (by outstanding principal balance  as
of  the  Cut-off  Date)  will  be  sold  by  BankAmerica  Housing  Services  and
approximately [    ]% will be sold by Bank of America. [Approximately [    ]% of
the Contracts in the Contract Pool were purchased by Bank of America from  SPFSC
immediately  prior  to its  conveyance  of such  Contracts  to the  Trust Fund.]
Subject to several exceptions, the Contracts being sold by Bank of America  will
have  one or both of  the following attributes: (i)  the amount financed is more
than 90% but not more than 95% of the Value (defined below) of any  Manufactured
Home  and (ii) the original term to maturity  is more than 20 years but not more
than 30 years.
 
    The Contracts  are all  [fixed] rate,  [actuarial] Contracts.  [None of  the
Contracts in the Contract Pool (i) is secured by a lien on real estate, (ii) was
purchased in bulk from an unrelated third party, (iii) 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,  (iv)  is  amortized  using  the  "simple interest"
amortization method or (v) has a variable Contract Rate or a Contract Rate which
steps up on particular dates.]
 
    Management of  BankAmerica  Housing Services  estimates  that in  excess  of
[    ]% of the Manufactured Homes are used as primary residences by the Obligors
under the Contracts secured by such Manufactured Homes.
 
    All  Contracts  have [fixed]  Contract Rates.  As of  the Cut-off  Date, the
Contract Rates on the Contracts  ranged from [     ]% to [     ]%. The  weighted
average  Contract Rate of the Contracts as of the Cut-off Date was approximately
[   ]%. As of the Cut-off Date, the Contracts had remaining scheduled maturities
of at least [  ] months but not  more than [   ] months, and original  scheduled
maturities  of at least  [  ] months  but not more  than [  ]  months. As of the
Cut-off Date, the Contracts had a weighted average remaining term to maturity of
approximately [   ] months, and  a weighted average  original term to  scheduled
maturity of approximately [  ] months. The average outstanding principal balance
of  the Contracts as of the Cut-off  Date was approximately $[         ] and the
outstanding principal balances of  the Contracts as of  the Cut-off Date  ranged
from  approximately $[         ] to $[          ]. The weighted average loan-to-
value ratio for the Contracts at origination was  approximately [    ]% and  the
loan-to-value  ratio of  the Contracts  at origination ranged  from [      ]% to
[   ]%. "Value" in  such calculation is equal to  the stated cash sale price  of
such  Manufactured Home,  including sales and  other taxes, plus,  to the extent
financed, filing  and  recording  fees  imposed by  law,  premiums  for  related
insurance   and   prepaid   finance  charges.   BankAmerica   Housing  Services'
underwriting practices 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
BankAmerica  Housing Services'  experience 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 -- 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 [  ] states and
the District of Columbia; approximately [    ]% of the Contracts by  outstanding
principal  balance as  of the  Cut-off Date  were secured  by Manufactured Homes
located in [           ], [     ]% in  [          ], [      ]% in [           ],

[     ]% in [        ], [    ]% in [     ], [    ]% in [        ] and [    ]% in
[         ]. No other state  represented more than 5% (by outstanding  principal
balance  as of  the Cut-off Date)  of the  Contracts. [None of  the Contracts is
secured by a Manufactured Home located in California.]
 
    Approximately [    ]% 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 [       ]%  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.

(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.

[BANKAMERICA HOUSING SERVICES' MANAGEMENT'S DISCUSSION AND ANALYSIS OF
DELINQUENCY, REPOSSESSION AND LOAN LOSS EXPERIENCE]
 
                   [TO PROSPECTUS SUPPLEMENT, AS APPLICABLE.]

                      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.
    
 
   
    The Contracts had maturities at origination ranging from [  ] months to [  ]
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. BankAmerica Housing Services 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  BankAmerica  Housing Services,  Bank of  America  or
SPFSC,  as the case  may be,] for  which at least  eighteen months of prepayment
information is  available,  as  described  in  Appendix  A  to  this  Prospectus
Supplement. For example, 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  in  Appendix A.  As a
result, the prepayment performance  of the Contracts  contained in the  Contract
Pool  might be higher or lower than  the prepayment performance of the contracts
reflected in  the historical  data. In  addition, although  BankAmerica  Housing
Services' management is aware of limited publicly available information relating
to historical rates of prepayment on manufactured housing contracts, BankAmerica
Housing  Services' management believes that  such information is not necessarily
indicative of the rate of prepayment that may be expected to be exhibited by the
Contracts. Nevertheless,  BankAmerica Housing  Services' management  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; Termination  Auction" and  "Certain Legal  Aspects of the
Contracts -- Transfers of Manufactured Homes; Enforceability of Restrictions  on
Transfer"  in the Prospectus[,  "Description of the  Certificates -- Termination
Auction"] and "Description of the  Certificates -- Optional Termination"  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  BankAmerica
Housing  Services remains the Servicer) to  purchase 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 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 the Class
A  Certificates and delaying  the amortization of the  Class B 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 199[ ]-[ ] Regular Certificates. If
a purchaser of Offered Certificates in either Class 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.
 
                                      S-22
<PAGE>
    The expected final scheduled  payment date on the  Contract with the  latest
maturity is in [            ].
 
    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 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 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.
 
    Although Contract Rates on the Contracts vary, prepayments on Contracts will
not affect the respective Pass-Through Rates on the Offered Certificates because
such Pass-Through Rates [are fixed and] will not exceed the Contract Rate on any
Contract  (less [      ]% per  annum for the  Monthly Servicing  Fee, as defined
hereinafter). 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 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 Class A  and/or Class B Certificates on the  related
Distribution  Date.  As  a result,  the  Available Distribution  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 Class A and/or Class B Certificateholders.
Although  no assurance can be given in this matter, BankAmerica Housing Services
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. 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
 
                                      S-23
<PAGE>
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.
 
    The table below sets forth with respect to each pool of contracts  described
in  Appendix A to this Prospectus Supplement (a) the initial aggregate principal
balance (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 [       ], 199[ ], (f) the WAC of
the contracts in the pool as of [       ], 199[ ] 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  [          ], 199[  ]
(calculated  as  the annual  rate of  the decline  in the  outstanding aggregate
principal balance exhibited over the life of the pool from prepayments using the
weighted average coupon  as of the  first day of  the month of  the sale of  the
pool).  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 or  in  Appendix A  to this
Prospectus Supplement.

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 cash distributions in reduction of
the Certificate
 
                                      S-24
<PAGE>
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 [     ]% per annum of  the then unpaid principal balance of
such Contracts in the first month of the life of the Contracts and an additional
[    ]% per annum  in each month thereafter (for example, [     ]% per annum  in
the  third month) until the [   ]th month. Beginning in the  [  ]th month and in
each month thereafter during the life  of the Contracts, 100% of the  Prepayment
Model assumes a constant prepayment rate of [    ]% 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;
"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.
 
   
    The  percentages and  weighted average  lives in  the following  tables were
determined assuming that (i)  scheduled interest and  principal payments on  the
Contracts  are  received in  a timely  manner  and prepayments  are made  at the
indicated percentages of the Prepayment Model set forth in the tables, (ii)  the
Trust Fund is terminated pursuant to a Termination Auction, (iii) the Contracts,
as of the Cut-off Date, will be grouped into [four] groups having the additional
characteristics   set   forth   in   the   table   entitled   "Assumed  Contract
Characteristics" below,  (iv)  the  Class  A  Certificates  initially  represent
[     ]% of the  entire ownership interest in the Trust  Fund and have a Class A
Pass-Through Rate  of [      ]%  per annum  and the  Class B  Certificates  will
initially  represent [    ]% of  the entire ownership interest in the Trust Fund
and have a  Class B 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
[    ]% 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 assumptions  in the
preceding paragraph, there are discrepancies between the payment characteristics
of the actual Contracts and the payment characteristics of the Contracts assumed
in preparing  the tables.  Any such  discrepancy  may have  an effect  upon  the
percentages  of  the Initial  Class A  Certificate Balance  and Initial  Class B
Certificate Balance outstanding and weighted average lives of such  Certificates
set  forth in the tables. In addition,  since the actual Contracts and the Trust
Fund have payment 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 [  ] 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.
 
    Based  on  the  foregoing  assumptions, the  following  tables  indicate the
resulting weighted average lives of the Offered Certificates and sets forth  the
percentage  of the Initial Class  A Certificate Balance and  the Initial Class B
Certificate Balance that would be outstanding  after each of the dates shown  at
the indicated percentages of the Prepayment Model.

                        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 exhibits  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.
    
 
    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
 
                                      S-27
<PAGE>
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
 
    [All  the Offered  Certificates initially  will be  issuable in  one or more
Global Certificates  registered in  the name  of  Cede as  the nominee  of  DTC.
Ownership  in Offered Certificates represented  by such Global Certificates will
only be  available  in the  form  of book-entries  on  the records  of  DTC  and
participating    members    thereof.    All   references    to    "holders"   or
"Certificateholders," and to authorized denominations, when used with respect to
the Offered Certificates issued as Global Certificates, shall reflect the rights
of beneficial owners  of the  Offered Certificates  ("Certificate Owners"),  and
limitations  thereof, as  they may be  indirectly exercised through  DTC and its
participating members, except as otherwise specified herein. See "Description of
the Certificates -- Global Certificates"  in the Prospectus. See the  Prospectus
under "Description of the Certificates -- Global Certificates" for a description
of  the  circumstances in  which Definitive  Certificates in  the future  may be
issued. Any  Offered  Certificates issued  as  Definitive Certificates  will  be
transferable  and exchangeable at  the corporate trust office  of the Trustee at
its Corporate Trust Department in [              ]  or, if it so elects, at  the
office  of an agent in [New York, New  York]. 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.
 
    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 Class  A Certificate or Class  B
Certificate  is the percentage obtained  from dividing the original denomination
of such Certificate by the Initial Class A Certificate Balance or Initial  Class
B Certificate Balance, respectively.
 
    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 and  BankAmerica Housing Services, under certain  conditions,
to repurchase Contracts sold by it with respect to which certain representations
and  warranties have  been breached and  not cured  and (v) the  proceeds of all
insurance policies described herein.
 
    Bank of America and BankAmerica  Housing Services will convey the  Contracts
to  the Trustee. See "The Contract Pool" herein and "-- Conveyance of Contracts"
below. 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
[       ], 199[ ], to the persons in whose names the Certificates are registered
at the close of  business on the  last business day of  the month preceding  the
month in which such distribution payment is made (the "Record Date").
 
CONVEYANCE OF CONTRACTS
 
    On  the date of  initial issuance of  the Certificates, Bank  of America and
BankAmerica Housing Services will convey  to the Trustee, without recourse,  all
right, title and interest of Bank of America and BankAmerica Housing Services 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 Date,  the
amount of each Scheduled
 
                                      S-28
<PAGE>
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
BankAmerica Housing Services 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,  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 or BankAmerica Housing
Services, 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  BankAmerica  Housing  Services,   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  relating to each
Contract. See "Risk Factors -- Security Interests in the Manufactured Homes" and
"Certain Legal Aspects of  the Contracts --  Security Interests in  Manufactured
Homes"  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. 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.
    
 
    Bank   of  America,  BankAmerica  Housing  Services  or  both  of  them,  as
applicable, will make certain representations and warranties to the Trustee with
respect to each Contract sold  by it, as of  the Closing Date (unless  expressly
stated  otherwise),  including the  following: (a)  as of  the Cut-off  Date, no
Contract is more than 59 days delinquent; (b) no provision of such Contract  has
been  waived,  altered or  modified  in any  respect,  except by  instruments or
documents identified in the related Contract File; (c) such Contract is a legal,
valid and binding  obligation of the  Obligor and is  enforceable in  accordance
with  its terms (except  as may be  limited by laws  affecting creditors' rights
generally or by general equity principles); (d) such Contract is not subject  to
any  right of rescission, set-off, counterclaim or defense; (e) such Contract is
covered by hazard insurance described under "Description of the Certificates  --
Servicing  Compensation and Payment  of Expenses; Certain  Matters Regarding the
Servicer -- A. Hazard Insurance Policies"  in the Prospectus; (f) such  Contract
was  either  (i) originated  by  a manufactured  housing  dealer acting,  to the
knowledge of BankAmerica Housing Services, in the regular course of its business
and purchased on  an individual  basis by  BankAmerica Housing  Services in  the
ordinary  course of  its business, [or]  (ii) originated  by BankAmerica Housing
Services in the ordinary course of its  business [or (iii) purchased by Bank  of
America,  BankAmerica Housing Services or SPFSC,  or any combination thereof, as
part of  bulk purchases  of manufactured  housing contracts  from other  private
lenders or finance companies, or from governmental agencies or instrumentalities
or  from other  entities]; (g)  such Contract was  neither originated  in nor is
subject to the laws of  any jurisdiction whose laws  would make the transfer  of
the  Contract or an interest therein to the Trustee pursuant to the Agreement or
pursuant to  the Certificates  unlawful;  (h) such  Contract complies  with  all
requirements of law; (i) such Contract has not been satisfied or subordinated in
whole  or in part or rescinded and  the Manufactured Home securing such Contract
has not been released from the lien of such Contract; (j) such Contract  creates
a valid and enforceable first-priority security interest in favor of BankAmerica
Housing  Services in  the Manufactured Home  covered thereby;  (k) such security
interest has  been assigned  to the  Trustee, and,  after such  assignment,  the
Trustee  has  a  valid and  perfected  first-priority security  interest  in the
Manufactured Home 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 or BankAmerica
 
                                      S-29

Housing Services, as  the case may  be, had  good and marketable  title to  such
Contract  sold by it, free  and clear of any  encumbrance, equity, loan, pledge,
charge, claim or security interest,  and it was the  sole owner thereof and  had
full right to transfer such Contract to the Trustee; (m) as of the Cut-off Date,
there  was no default, breach, violation  or event permitting acceleration under
such Contract and no event which, with notice and the expiration of any grace or
cure period,  would  constitute  such  a default,  breach,  violation  or  event
permitting  acceleration (except  payment delinquencies permitted  by clause (a)
above), and Bank of America or BankAmerica Housing Services, 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's or BankAmerica Housing
Services',  as applicable, no  liens or claims  which have been  filed for work,
labor or materials affecting a  Manufactured Home securing such Contract,  which
are  or may be liens prior  to or equal with or  subordinate to the lien of such
Contract; (o) such Contract is a  fully-amortizing loan with a [fixed]  Contract
Rate  and provides for level  payments over the term  of such Contract; (p) such
Contract contains customary  and enforceable  provisions such as  to render  the
rights  and remedies of the holder  thereof adequate for realization against the
collateral of the benefits of the security; (q) the information contained in the
Contract Schedule with respect to such  Contract is true and correct; (r)  there
is  only  one  original of  such  Contract; (s)  such  Contract did  not  have a
loan-to-value  ratio  at  origination  greater   than  100%;  (t)  the   related
Manufactured  Home is not considered or classified as part of the real estate on
which it is located under the laws  of the jurisdiction in which it is  located,
and  as of the Closing Date such Manufactured  Home is, to the knowledge of Bank
of America or BankAmerica Housing Services, as applicable, free of damage and in
good  repair;  (u)  such  Contract  is  a  "qualified  mortgage"  under  Section
860G(a)(3)  of the  Code; (v) the  related Manufactured Home  is a "manufactured
home" within the meaning  of Section 5402(6)  of Title 42  of the United  States
Code  and, as to  each Contract sold  by Bank of  America or BankAmerica Housing
Services to the Trust  Fund, BAFSB is a  federally-chartered savings bank as  of
the   time   of  such   Contract's   origination  as   required   under  Section
3(a)(41)(A)(ii) of the Exchange Act; (w)  such Contract is secured by a  "single
family  residence" within the meaning of Section 25(e)(10) of the Code; (x) such
Contract has been stamped to indicate its assignment to the Trustee; and (y) the
Contract with the lowest  Contract Rate has  a Contract Rate of       % and  the
Contract  with the highest Contract Rate has a Contract Rate of     %. 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  or  BankAmerica  Housing
Services,  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 or
BankAmerica Housing Services, as the case  may be, becomes aware, or after  Bank
of America's or BankAmerica Housing Services' receipt of written notice from the
Trustee  or the Servicer, of a breach  of any representation or warranty of Bank
of America or BankAmerica Housing Services, 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  nor BankAmerica
Housing Services  will be  required  to repurchase  or substitute  any  Contract
relating  to a  Manufactured Home  located in any  jurisdiction on  account of a
breach of the representation and warranty  described in clause (j) above  solely
on  the basis of the failure by Bank of America or BankAmerica Housing Services,
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  (other  than a  notation  or  transfer  instrument
necessary  to show Bank of America or BankAmerica Housing Services 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 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-
 
                                      S-30
<PAGE>
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  or BankAmerica  Housing
Services,  as applicable, were to result  from proceedings brought by a receiver
or conservator of Bank of America or BankAmerica Housing Services, 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"),  BankAmerica Housing  Services or,  where applicable,  Bank of
America, 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.
BankAmerica Housing Services or Bank of America, 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 [   ] by [         ][and [   ] by [         ] (if rated by

    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][last  day of such Collection  Period or, if such  day is not a business
day, on the  first business day  thereafter]. 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
BankAmerica Housing Services or Bank of America 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 it  or Bank  of  America or  BankAmerica Housing  Services  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 199[ ]-[ ] Regular  Certificates
will be applied first to the holders of the Class A Certificates and then 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 of principal and interest to holders of each Class of
Certificates  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. Interest  will be
calculated on the basis of a 360-day year consisting of twelve 30-day months.
 
    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
 
                                      S-32
<PAGE>
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.
 
    On  each  Distribution  Date,  the  Available  Distribution  Amount  will be
distributed in the following amounts and in the following order of priority:
 
        (i) to the Class A Certificateholders, the Class A Interest Distribution
    Amount;
 
        (ii)  to  the   Class  A  Certificateholders,   the  Formula   Principal
    Distribution  Amount until  the Class  A Certificate  Balance is  reduced to
    zero;
 
       (iii)  to  the   Class  B  Certificateholders,   the  Class  B   Interest
    Distribution Amount;
 
        (iv)  to the Class B Certificateholders, any remaining Formula Principal
    Distribution Amount after  distributions under clause  (ii) above until  the
    Class B Certificate Balance is reduced to zero; and
 
        (v)   to  the  Class  R   Certificateholders,  any  remaining  Available
    Distribution Amount.
 
    As to any Distribution Date, the  "Class A Interest Distribution Amount"  is
equal to the sum of (i) one month's interest at the Class A Pass-Through Rate on
the Class A Certificate Balance and (ii) any previously undistributed shortfalls
in  interest  due  to  the  Class  A  Certificateholders  in  respect  of  prior
Distribution Dates; the "Class B Interest  Distribution Amount" is equal to  the
sum  of (i) one month's interest at the Class B Pass-Through Rate on the Class B
Certificate Balance and (ii) any previously undistributed shortfalls in interest
due to the Class  B Certificateholders in respect  of prior Distribution  Dates.
Any  shortfall in interest due to Certificateholders will, to the extent legally
permissible, bear interest at the related Class A or Class B Pass-Through Rate.
 
    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.
 
    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  or BankAmerica  Housing Services,  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.
 
                                      S-33
<PAGE>
    The "Class A Certificate Balance" as of any Distribution Date is the Initial
Class A Certificate Balance less all  amounts previously distributed to Class  A
Certificateholders on account of principal; the "Class B Certificate Balance" as
of  any Distribution Date  is the Initial  Class B Certificate  Balance less all
amounts previously distributed to holders of the Class B Certificates on account
of principal. In no event shall the aggregate distributions of principal to  the
holders  of the  Class A  and Class  B Certificates  exceed the  Initial Class A
Certificate Balance and the Initial Class B Certificate Balance, respectively.
 
SUBORDINATION
 
    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  herein,  to  such  rights  of  the  holders  of  the  Class A
Certificates. This  subordination  is  intended to  enhance  the  likelihood  of
regular receipt by the holders of the Class A Certificates of the full amount of
interest  and  principal  distributable  thereon  and  to  afford  such  holders
protection against losses on Liquidated Contracts.
 
    The protection afforded to the holders  of Class A Certificates by means  of
the  subordination  of the  Class  B Certificates  will  be accomplished  by the
application of the Available  Distribution Amount in  the order specified  under
"--   Distributions"  above.  Accordingly,  in  the  event  that  the  Available
Distribution Amount on  any Distribution Date  is not sufficient  to permit  the
distribution  of the amount of interest and the specified portion of the Formula
Principal Distribution Amount due  to the holders of  the Class A  Certificates,
the  subordination will  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 holders of  the Class B Certificates,
until any shortfall in distributions to the holders of the Class A  Certificates
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 199[ ]-[ ] 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 Excess Interest during the same Collection Period exceeds interest
distributions due to the holders of  the Series 199[ ]-[ ] Regular  Certificates
and the Monthly Servicing Fee.
 
    The  effect of any losses on Liquidated Contracts during a Collection Period
in excess of the aggregate  of Excess Interest generally  will be to 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 Certificateholders and the Class A 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 [June 1996]:

                                            10th day of each month or, if the 10th day is
                                            not a business day, the next business day.)
Succeeding months follow the pattern of (B) through (E).
</TABLE>
    
 
- ------------------------
(A) The Cut-off Date Pool Principal Balance on [May 1, 1996] 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 [June 10, 1996]. 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  [June  10,  1996]  are  described  under
    "-- Payments on Contracts; Certificate Account" above.
 
(C) Distributions  on [June  10, 1996]  will be  made to  Certificateholders  of
    record at the close of business on [May 31, 1996].
 
   
(D)  On [June 5, 1996] (three business days prior to the Distribution Date), the
    Servicer will determine the amounts of principal and interest which will  be
    passed through on [June 10, 1996] to Certificateholders.
    
 
   
(E)  On  [June 10,  1996],  the amounts  determined on  [June  5, 1996]  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  199[ ]-[ ]  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 199[  ]-[ ]
Regular Certificateholders rather than to guarantee or insure against losses.
 
                                      S-35
<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.
 
REPORTS TO CERTIFICATEHOLDERS
 
    The Trustee will  include with  each distribution to  a Certificateholder  a
statement as of the related Distribution Date setting forth, among other things:
 
         (1)   the aggregate  amount distributed on the  Class A Certificates on
    such Distribution Date;
 
         (2)  the amount of such distribution on such Class A Certificate  which
    constitutes principal;
 
         (3)   the amount of such distribution on such Class A Certificate which
    constitutes interest;
 
         (4)  the remaining Class A Certificate Balance;
 
         (5)  the aggregate  amount distributed on the  Class B Certificates  on
    such Distribution Date;
 
         (6)   the amount of such distribution on such Class B Certificate which

         (9)   the Monthly  Servicing Fee payable on  such Distribution Date and
    the amount of any other fees payable out of the Trust Fund;
 
        (10)  the number of and aggregate unpaid principal balance of  Contracts
    with  payments  delinquent  31  to  59,  60 to  89,  and  90  or  more days,
    respectively;
 
        (11)  the  number of Contracts  that were repurchased  or replaced by  a
    Seller  in accordance with the Agreement during the prior Collection Period,
    identifying such Contracts and  (i) the Repurchase  Price of such  Contracts
    and  (ii) the amount, if any, paid by such Seller due to the differences, if
    any, between the remaining principal balances of the replaced Contracts  and
    the Eligible Substitute Contracts;
 
        (12)   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;
 
        (13)    the aggregate  liquidation  losses (less  costs  of liquidation)
    realized by  the  Trust  Fund  through  the  Collection  Period  immediately
    preceding such Distribution Date, expressed in dollars;
 
        (14)    the aggregate  liquidation  losses (less  costs  of liquidation)
    realized by  the  Trust  Fund  through  the  Collection  Period  immediately
    preceding  such Distribution Date, expressed as  a percentage of the Cut-off
    Date Pool Principal Balance;
 
        (15)  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;
 
        (16)  the weighted average Contract  Rate for the Contract Pool for  the
    Collection Period immediately preceding the month of such Distribution Date;
    and
 
        (17)   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
199[  ]-[ ] Regular Certificate of record  at any time during such calendar year
as to the aggregate of amounts reported pursuant to clauses (2) and (3) and  (6)
and (7), as the case may be, above for such calendar year.
    
 
   
TERMINATION AUCTION
    
 
   
    [The  Agreement provides that within  ninety days following the Distribution
Date as of which the  Pool Scheduled Principal Balance is  less than 10% of  the
Cut-off  Date Pool  Principal Balance,  the Trustee  shall solicit  bids for the
purchase of  the  Contracts remaining  in  the Trust  Fund.  In the  event  that
satisfactory  bids  are received  as described  in the  Agreement, the  net sale
proceeds will be distributed to Certificateholders, in
    
 
                                      S-36
<PAGE>
   
the same order of priority as collections received in respect of the  Contracts.
If  satisfactory bids are  not received, the  Trustee shall decline  to sell the
Contracts and shall not be under any  obligation to solicit any further bids  or
otherwise  negotiate any further sale of the Contracts. Under the Agreement, the
winning bid must  equal or  exceed the  Minimum Termination  Amount (as  defined
below). Such sale and consequent termination of the Trust Fund must constitute a
"qualified  liquidation"  of the  Trust  Fund under  Section  860F of  the Code,
including the  requirement that  the qualified  liquidation takes  place over  a
period  not to exceed 90 days. See  "Description of the Certificates -- Optional
Termination" herein and in the Prospectus.]
    
 
OPTIONAL TERMINATION
 
   
    If the Trust Fund  has not terminated pursuant  to a successful  Termination
Auction,  the Agreement  also provides that  on any Distribution  Date after the
First Distribution Date on  which the Pool Scheduled  Principal Balance is  less
than  5% 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  Class  A
Certificateholders an amount equal to  the Class A Certificate Balance  together
with  any shortfall in interest due to the Class A Certificateholders in respect
of prior Distribution Dates and one month's interest on the Class A  Certificate
Balance  at the Class A Pass-Through Rate, and to the Class B Certificateholders
an amount equal to the Class  B Certificate Balance together with any  shortfall
in  interest  due  to  the  Class  B  Certificateholders  in  respect  of  prior
Distribution Dates and one month's interest  on the Class B Certificate  Balance
at  the  Class  B  Pass-Through  Rate  (collectively  the  "Minimum  Termination
Amount").
    
 
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[,]" [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 "-- Termination Auction"].
    
 
   
    Upon   presentation  and  surrender  of  the   Series  199[  ]-[  ]  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  the amount  distributable
thereon  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 199[ ]-[ ] 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.
 
                                      S-37
<PAGE>
   
    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 "Trustee")  has its  corporate trust  offices  at
[                     ]. 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 [        ]  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.
 
                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
   
    The discussion under this heading has been prepared and reviewed by Morrison
&  Foerster  LLP, special  counsel to  Bank of  America and  BankAmerica Housing
Services, and  supplements  the discussion  under  "Certain Federal  Income  Tax
Consequences"  in the Prospectus. Morrison & Foerster LLP is of the opinion that
the  statements  contained  herein  and   under  "Certain  Federal  Income   Tax
Consequences" in the Prospectus, to the extent they constitute matters of law or
legal  conclusions with respect  thereto, are correct  in all material respects,
under the assumptions stated herein and therein  and under the law in effect  as
of  the  date  hereof. In  connection  with  the issuance  of  the Certificates,
Morrison & Foerster LLP will deliver an opinion regarding certain federal income
tax matters, including an opinion to the foregoing effect. That opinion will  be
filed with the Commission as an exhibit to a Current Report on Form 8-K promptly
following the issuance of the Certificates.
    
 
    The  Trust  Fund  will  elect  to be  treated  as  a  "real  estate mortgage
investment conduit"  ("REMIC")  for federal  income  tax purposes.  The  Offered
Certificates  represent  regular  interests in  the  REMIC and,  hence,  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
 
                                      S-38
<PAGE>
federal  income tax purposes with  payment terms equivalent to  the terms of the
Offered Certificates. Holders of Offered Certificates will be required to report
income with  respect  to such  Offered  Certificates under  an  accrual  method,
regardless of their normal tax accounting method.
 
    The Offered Certificates, depending on their respective issue prices, may be
issued with original issue discount ("OID") for federal income tax purposes.
 
    The  Offered Certificates  will be treated  as regular interests  in a REMIC
under Section  860G  of the  Internal  Revenue Code  of  1986, as  amended  (the
"Code"). Accordingly, the Offered Certificates will be treated as (i) qualifying
real  property loans within the  meaning of Section 593(d)(1)  of the Code, (ii)
assets described in Section  7701(a)(19)(C) of the Code  and (iii) "real  estate
assets" within the meaning of Section 856(c)(5) of the Code, in each case to the
extent described in the Prospectus. Interest on the Offered Certificates will be
treated  as interest on obligations secured by mortgages on real property within
the meaning of Section 856(c)(B) of the Code to the same extent that the Offered
Certificates are treated as real estate assets.
 
    If an  Offered Certificate  is  sold, exchanged,  redeemed or  retired,  the
seller  of such Certificate will recognize gain  or loss equal to the difference
between the amount realized on the sale, exchange, redemption, or retirement and
such seller's adjusted  basis in  the Offered Certificate.  Such adjusted  basis
generally  will  equal  the  cost  of the  Offered  Certificate  to  the seller,
increased by any OID and market  discount included in the seller's gross  income
with  respect to the  Offered Certificate, and  reduced (but not  below zero) by
payments included in the stated redemption price at maturity previously received
by the seller and by any amortized  premium. Similarly, a holder who receives  a
payment  that is part of  the stated redemption price  at maturity of an Offered
Certificate will recognize gain equal  to the excess, if  any, of the amount  of
the  payment over  the holder's  adjusted basis  in the  Offered Certificate. An
Offered Certificateholder who  receives a final  payment that is  less than  the
holder's  adjusted basis in  the Offered Certificate  will generally recognize a
loss. Except as provided in the following  paragraph, any such gain will be  and
any such loss may be capital gain or loss, provided that the Offered Certificate
is  held as a  "capital asset" (generally, property  held for investment) within
the meaning of Code Section 1221.
 
    Gain from the sale or other disposition of an Offered Certificate that might
otherwise be a 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  includible  in such  holder's  income  with respect  to  the  Offered
Certificate had income accrued thereon at a rate equal to 110% of the applicable
federal  rate as defined  in Code Section  1274(d) determined as  of the date of
purchase of such Offered Certificate,  over (ii) the amount actually  includible
in such holder's income.
 
    See "Certain Federal Income Tax Consequences" in the Prospectus.
 
                              ERISA CONSIDERATIONS
 
GENERAL
 
    The  Employee Retirement Income Security Act  of 1974, as amended ("ERISA"),
imposes certain restrictions on employee benefit plans that are subject to ERISA
("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.
 
CLASS A CERTIFICATES
 
    [The  Department  of   Labor  ("DOL")  has   granted  to  [Underwriter]   an
administrative exemption (DOL Prohibited Transaction Exemption [    ], [  ] Fed.
Reg.   [               ]  (19      )   (the   "Exemption"))   from   certain  of
 
                                      S-39
<PAGE>
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.
[Underwriter] has  advised the  Sellers that  the Exemption  will apply  to  the
acquisition and holding of Class A 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  Class A
Certificates are the following:
 
    [(1) The acquisition  of the  Class A  Certificates by  a Plan  is on  terms
(including  the  price  for the  Class  A  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 Class A Certificates acquired
by  the Plan are not subordinated to the rights and interests evidenced by other
Certificates of the Trust.
 
    [(3) The Class A 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 [   ] or [   ].
 
    [(4)  The Trustee is not an affiliate  of the Underwriters, Bank of America,
BankAmerica Housing  Services,  SPFSC, 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 Class A Certificates represents not more
than reasonable compensation for underwriting the Class A 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 BankAmerica
Housing  Services  represents   not  more  than   reasonable  compensation   for
BankAmerica  Housing Services' services under the Agreement and reimbursement of
BankAmerica Housing Services' 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. [Underwriter]  has advised the Sellers  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  the related  excise tax provisions  of Section  4975 of the
Code, the direct or indirect sale, exchange or transfer of Class A  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
 
                                      S-40
<PAGE>
Class  A 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 Class  A Certificates, at
least 50% in Percentage Interests of  such Class of Certificates 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 Class  A 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 Class A Certificates, no more
than 25% of  the assets  of the  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.
 
    [This  exemption  also  applies to  the  direct or  indirect  acquisition or
disposition of Class A Certificates by a Plan in the secondary market if certain
conditions are met and the continued holding of Class A Certificates acquired in
initial or secondary markets.
 
    [Before purchasing a Class A 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
Class A Certificate should also carefully review with its own legal advisors the
applicability of the  fiduciary duty  and prohibited  transaction provisions  of
ERISA  and  the  Code to  such  investment.  See "ERISA  Considerations"  in the
Prospectus.]
 
[CLASS B CERTIFICATES
 
    [A PLAN OR FIDUCIARY SHOULD NOT PURCHASE OR HOLD THE CLASS B CERTIFICATES AS
SUCH ACTIONS MAY GIVE  RISE TO A TRANSACTION  PROHIBITED UNDER ERISA OR  SECTION
4975  OF THE  CODE. SEE  "ERISA CONSIDERATIONS"  IN THE  PROSPECTUS. BECAUSE THE
CLASS B CERTIFICATES DO NOT MEET THE REQUIREMENTS OF THE EXEMPTION, IT DOES  NOT
APPLY TO THEM.
 
    [IN  ADDITION,  NO TRANSFER  OF A  CLASS B  CERTIFICATE SHALL  BE REGISTERED
UNLESS THE PROSPECTIVE TRANSFEREE  PROVIDES THE TRUSTEE,  THE SELLER[S] 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  THE
EMPLOYEE  RETIREMENT  INCOME  SECURITY ACT  OF  1974, AS  AMENDED  ("ERISA"), OR
SECTION 4975 OF THE INTERNAL REVENUE CODE OF 1986, AS AMENDED (THE "CODE"),  THE
TRUSTEE  OF ANY SUCH PLAN  OR A PERSON ACTING  ON BEHALF OF ANY  SUCH PLAN NOR A
PERSON USING THE ASSETS OF ANY SUCH PLAN AND (2) SUCH TRANSFEREE IS AN INSURANCE
COMPANY WHICH  IS  PURCHASING  SUCH  CERTIFICATES WITH  FUNDS  CONTAINED  IN  AN
"INSURANCE  COMPANY GENERAL ACCOUNT" (AS SUCH TERM IS DEFINED IN SECTION V(E) OF
THE PROHIBITED TRANSACTION CLASS  EXEMPTION 95-60 ("PTCE  95-60")) AND THAT  THE
PURCHASE  AND HOLDING OF SUCH CERTIFICATES ARE  COVERED UNDER PTCE 95-60; OR (B)
AN OPINION OF COUNSEL  (A "BENEFIT PLAN OPINION")  SATISFACTORY TO THE  TRUSTEE,
THE  SELLER[S] AND THE SERVICER,  AND UPON WHICH THE  TRUSTEE, THE SELLER[S] AND
THE SERVICER SHALL  BE ENTITLED  TO RELY,  TO THE  EFFECT THAT  THE PURCHASE  OR
HOLDING  OF  SUCH CLASS  B CERTIFICATE  BY THE  PROSPECTIVE TRANSFEREE  WILL NOT
RESULT IN  THE ASSETS  OF THE  TRUST FUND  BEING DEEMED  TO BE  PLAN ASSETS  AND
SUBJECT  TO THE PROHIBITED TRANSACTION PROVISIONS OF  ERISA OR THE CODE AND WILL
NOT SUBJECT THE  TRUSTEE, THE  SELLER[S] 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 SELLER[S] OR THE SERVICER.]
 
                                    RATINGS
 
    It  is a  condition to  the issuance  of the  Certificates that  the Class A
Certificates be rated "[   ]" by [        ] and that the Class B Certificates be
rated  "[       ]"  by  [                  ].  A   security  rating  is  not   a
 
                                      S-41
<PAGE>
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 Class A Certificates should  be evaluated independently of similar  security
ratings assigned to other kinds of securities.
 
    The  ratings assigned by [        ] 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. [     ] 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. [      ]
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 [          ], [         ], New York, New York
[     ], telephone [(   )-        ].
 
    The Sellers have not requested a  rating on the Offered Certificates by  any
rating  agency other than [             ]. 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 [            ].
 
                                LEGAL INVESTMENT
 
    The [Class A] 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
[Class A] Certificates constitute legal investments for such investors.
 
    [Because the Class  B Certificates  will not, at  the time  of issuance,  be
rated  in one  of the  two highest  rating categories  of [      ],  the Class B
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  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 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.]
 
                             METHOD OF DISTRIBUTION
 
    Subject to  the terms  and conditions  of the  Underwriting Agreement  dated
[           , 19   ] (the "Underwriting Agreement"),  the Sellers have agreed to
sell, and [each of        ] (the "Underwriters") has agreed to purchase from the
Sellers the Offered Certificates offered hereby upon issuance.
 
    In the Underwriting Agreement, the Underwriters have agreed, subject to  the
terms  and  conditions  set  forth  therein,  to  purchase  all  of  the Offered
Certificates offered hereby if  any Offered Certificates  are purchased. In  the
event of default by an Underwriter, the Underwriting Agreement provides that, in
certain circumstances, the Underwriting Agreement may be terminated.
 
    Distribution  of the Offered Certificates will be  made from time to time in
negotiated transactions or otherwise at varying  prices to be determined at  the
time  of sale. Proceeds to the Sellers from the sale of the Offered Certificates
will be [    ]% of the initial Class A Certificate Balance plus accrued interest
thereon from the  Cut-off Date,  but before  deducting expenses  payable by  the
Sellers.  In connection with  the purchase and sale  of the Offered Certificates
offered hereby, the Underwriter may be deemed to have received compensation from
the Sellers in the form of underwriting discounts.
 
                                      S-42
<PAGE>
    The Underwriting  Agreement provides  that the  Sellers will  indemnify  the
Underwriters  against  certain  liabilities,  including  liabilities  under  the
Securities Act of 1933, as amended,  or contribute to payments the  Underwriters
may be required to make in respect thereof.
 
                                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.]
 
                                 LEGAL MATTERS
 
   
    Certain  legal matters relating to the Offered Certificates, including legal
matters relating  to material  federal income  tax consequences  concerning  the
Offered Certificates, will be passed upon for the Sellers by Morrison & Foerster
LLP, Irvine, California and for the Underwriters by        .

                                                                      APPENDIX A
 
                     PREPAYMENT EXPERIENCE OF CERTAIN POOLS
 
    Certain  statistical  information  relating to  the  prepayment  behavior of
certain but not  all pools  of manufactured  housing contracts  sold by  SPHSI[,
SPFSC,  Bank of America]  or BankAmerica Housing Services  and serviced by SPHSI
and now BankAmerica Housing Services is  set forth below in tabular form.  These
tables relate to [    ] 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 these tables contain useful information
with  respect to  the expected  prepayment behavior  of any  particular contract
pool, prospective  Certificateholders  should consider  the  following:  neither
BankAmerica  Housing Services  nor SPHSI  has performed  statistical analysis to
determine whether  the  contracts  to  which such  tables  relate  constitute  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  tables relate.  FOR
THESE  REASONS, AND BECAUSE OF THE UNPREDICTABLE NATURE OF THE FACTORS DESCRIBED
HEREIN  AS  INFLUENCING  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 TABLES
RELATE  WILL EXHIBIT PREPAYMENT  BEHAVIOR SIMILAR TO  THE BEHAVIOR SUMMARIZED IN
SUCH TABLES FOR THE PERIODS COVERED BY SUCH TABLES.
 
    In addition to the foregoing, prospective Certificateholders should consider
that the tables set  forth below are  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 following tables set forth, with  respect to each sold pool, an  initial
aggregate  principal balance (calculated as of the first day of the month of the
sale),  the  decline  in  outstanding  aggregate  principal  balance  for   each
subsequent  month (whether  due to  liquidations, scheduled  principal payments,
principal prepayments or repurchases), the constant prepayment rate ("CPR")  for
each  such month and for the life of the  pool through [19  ] (calculated as the
annual rate of the decline in the outstanding aggregate principal balance due to
liquidations, principal prepayments and repurchases exhibited during such  month
or  over the life of  the pool) and the  weighted average annual percentage rate
("WAC") of the contracts in each  pool as of the first  day of the month of  the
sale  of  each pool  and  the first  day  of every  month  thereafter up  to and
including [    1, 199 ]. The estimated average age of each pool as of the  first
day  of the  month of  sale is listed  in "Prepayment  and Yield Considerations"
herein.

                         BANKAMERICA HOUSING SERVICES,
                         AN UNINCORPORATED DIVISION OF
                   BANK OF AMERICA, FSB, SELLER AND SERVICER
 
    BankAmerica Manufactured  Housing Contract  Trust Pass-Through  Certificates
("Certificates")  of one or more series (each, a "Series") may be sold from time
to time under this Prospectus and a Prospectus Supplement for each such  Series.
The  Certificates  of  each Series  may  be issued  in  one or  more  classes or
subclasses (each, a "Class"), as  further described herein. If the  Certificates
of  a Series are  issued in more  than one Class,  all or less  than all of such
Classes may be sold under this Prospectus, and there may be separate  Prospectus
Supplements for one or more of such Classes so sold. Any reference herein to the
Prospectus  Supplement relating  to a  Series comprised  of more  than one Class
should be understood to refer to each of the Prospectus Supplements relating  to
the Classes sold hereunder.
 
   
    The  Certificates of each  Series will represent  interests, as specified in
the related Prospectus Supplement,  in one or  more of a  number of trust  funds
(each,  a "Trust Fund")  created by Bank  of America National  Trust and Savings
Association ("Bank of America" or "Seller") or BankAmerica Housing Services,  an
unincorporated  division of Bank of America, FSB ("BankAmerica Housing Services"
or "Seller,"  and, together  with Bank  of America,  the "Sellers")  or both.  A
separate  Trust Fund will  be established for each  Series of Certificates. Each
Trust Fund will include a pool (each, a "Contract Pool") of manufactured housing
installment sales contracts  and installment loan  agreements (the  "Contracts")
together  with  certain  contract  rights  and  other  rights  relating  to such
Contracts (as  discussed below)  (the Contracts  and such  other property  being
referred  to as the "Trust Fund"). 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, BankAmerica  Housing Services  or
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 business  or (ii) purchased  by Bank of America,
BankAmerica Housing Services, SPFSC,  or any combination  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 and/or interest 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 BankAmerica Housing Services  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  BankAmerica Housing
Services, as the case may  be, with respect to the  Contracts sold by it in  the
related  Contract Pool  and, in  the case  of BankAmerica  Housing Services, 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.
 
    An  election may  be made to  cause the Trust  Fund relating to  a Series of
Certificates to  be treated  as a  real estate  mortgage investment  conduit  (a
"REMIC")  for  federal  income tax  purposes.  See "Certain  Federal  Income Tax
Consequences" herein.
 
                INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE

Servicer  will provide or cause to be provided without charge a copy of any such

                                  If  a Contract  Pool contains  Step-Up Rate  Contracts (as
                                  defined herein),  the related  Prospectus Supplement  will

                                  such Contracts, the period during which the Contract Rates
                                  for such  Contracts  will  be stepped  up,  the  range  of

                                  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

                                  may also  include  additional information  concerning  the

                                  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  and/or interest  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 such  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
                                  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,  losses  on  Contracts  and  repurchases  of
                                  Contracts  under certain  conditions or  other events. See
                                  "The Contract Pools," "Description of the Certificates  --

                                  herein as distributions of "Regular Principal." The  Total

                                  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

                                  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.
                                  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

                                  holders of Certificates of  a particular 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 Distribution

                                  Prospectus Supplement,  from  interest  collected  on  the
                                  underlying Contract Pool, from funds available from one or
                                  more  forms of credit support or from such other source as
                                  may  be  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

                                  such   Distribution  Date),  calculated  at  a  rate  (the
                                  "Pass-Through Rate") specified  in the related  Prospectus

                                  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

                                  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 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  related Prospectus Supplement.  See
                                  "Credit   and  Liquidity   Enhancement"  herein   and  the

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 related  Trust Fund)  in the  absence  of
                                  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

                                  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 "ERISA Considerations" herein

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"

                                  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 Prospectus.
                                  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.

                                  RISK FACTORS
 
    Prospective  purchasers of Certificates should consider, among other things,
the following factors in connection with the purchase of Certificates:
 
    1.  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.
 
   
    2.   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.
    
 
   
    3.   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.
    
 
   
    4.    DEPRECIATION OF  MANUFACTURED HOMES.   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  principal balance  of  the  related
Contract. See "The Contract Pools" herein and "The Contract Pool" in the related
Prospectus  Supplement. To the extent the Servicer has to repossess Manufactured
Homes relating to  Contracts in  a Contract  Pool (or  to the  extent there  are
casualty  losses  on the  related Manufactured  Homes), there  are likely  to be
liquidation losses on the Contracts in  such Contract Pool, which 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.
    
 
   
    5.  NO RECOURSE.  Neither  Bank of America nor BankAmerica Housing  Services
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 BankAmerica
Housing Services, as the case may be,  with respect to the Contracts sold by  it
in  the related Contract Pool, and, in the case of BankAmerica Housing Services,
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
    
 
                                       13
<PAGE>
AMERICA, BANKAMERICA  HOUSING SERVICES,  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.
 
   
    6.  SECURITY INTERESTS IN  THE MANUFACTURED HOMES.   On the date of  initial
issuance  of Certificates in any Series,  Bank of America or BankAmerica Housing
Services or both will  convey the related Contracts  to the related Trust  Fund.
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, but generally not 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" 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  BankAmerica
Housing  Services was  conducting business  from approximately  February 1993 to
February 1994),  "Security  Pacific Housing  Services,  a Division  of  Bank  of
America,  FSB" (the name under which BankAmerica Housing Services was conducting
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
BankAmerica Housing  Services (under  one  of the  foregoing names)  as  secured
party.  Because  of  the  expense  and  administrative  inconvenience  involved,
BankAmerica Housing Services 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. In some  states,
in  the  absence of  such  an amendment,  notation,  execution or  delivery, the
assignment to the  Trustee of the  security interest in  the Manufactured  Homes
located  therein  may not  be 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 BankAmerica Housing  Services,
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
BankAmerica Housing Services. See "Description of the Certificates -- Conveyance
of  Contracts"  in the  applicable Prospectus  Supplement  for a  description of
certain limited circumstances under which  BankAmerica Housing Services 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 BankAmerica Housing Services  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.
    
 
   
    7.   TRANSFER  OF CONTRACTS AND  RELATED SECURITY INTERESTS.   Each Contract
generally will  be  "chattel paper"  as  defined in  the  UCC as  in  effect  in
California  (where  BankAmerica Housing  Services' 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. BankAmerica Housing  Services or Bank of America, as
the case may be,
    
 
                                       14
<PAGE>
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,
BankAmerica Housing Services 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  BankAmerica
Housing Services' or Bank of America's (or an affiliate's) creditors, a receiver
or conservator of BankAmerica Housing Services or Bank of America or a receiver,
conservator or trustee in bankruptcy of an affiliate
thereof  that sold  such Contracts  to BankAmerica  Housing Services  or Bank of
America.
 
    In addition,  a  federal  circuit  court decision  may  adversely  affect  a
Trustee's  interest  in  Contracts  comprising  a  Contract  Pool  even  if such
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 or BankAmerica Housing Services has sold Contracts to Bank of America or
BankAmerica  Housing Services  and becomes  a debtor  in a  proceeding under the
federal bankruptcy code,  and the  court with jurisdiction  for such  bankruptcy
proceeding  were to  follow the  reasoning of the  Tenth Circuit  and apply such
reasoning to chattel paper, Certificateholders  could experience a delay in,  or
reduction  of, distributions as  to the Contracts  that constitute chattel paper
and were sold by such debtor.
 
   
    8.  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, BankAmerica Housing Services 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 BankAmerica Housing Services 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 BankAmerica Housing Services
nor Bank of America will have any obligation to repurchase any Contract  because
of limitations imposed under the Relief Act, however.
    
 
   
    9.   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
    
 
                                       15
<PAGE>
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.
 
   
    10.  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.
    
 
   
    11.   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.
    
 
   
    12.   INSOLVENCY,  RECEIVERSHIP OR BANKRUPTCY  OF CONTRACT SELLERS.   In the
event of an insolvency, conservatorship  or receivership of BankAmerica  Housing
Services 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
BankAmerica Housing Services  and becomes  a debtor  in a  proceeding under  the
federal bankruptcy code, the sale of Contracts by Bank of America or BankAmerica
Housing  Services 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.
    
 
   
    13.   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 BankAmerica  Housing Services  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  BankAmerica Housing Services  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, BankAmerica Housing Services  or SPFSC or purchased by Bank  of
America,  BankAmerica  Housing Services  or  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, BankAmerica Housing Services or 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. 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,  BankAmerica Housing Services or both of them will convey the Contracts
comprising the  related Contract  Pool to  the related  Trust Fund.  BankAmerica
Housing  Services,  as  Servicer, will  obtain  and maintain  possession  of all
Contract documents. If specified in the related Prospectus Supplement, the terms
of the  conveyance of  some  or all  of such  Contracts  from Bank  of  America,
BankAmerica  Housing Services or  both to the applicable  Trust Fund may provide
for the retention by Bank of  America, BankAmerica Housing Services or both  (as
the case may
 
                                       16
<PAGE>
be)  of the  right to receive  a Retained Yield.  The right of  Bank of America,
BankAmerica Housing  Services  or both  (as  the case  may  be) to  receive  any
Retained  Yield relating to any Contract or any Contract Pool may be on a parity
with, or subordinate to, the right of the applicable Trust Fund to receive other
amounts due  thereon,  all  as  more  specifically  set  forth  in  the  related
Prospectus Supplement.
 
    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  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
 
                                       17
<PAGE>
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  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") 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")
 
                                       18

on  the real estate on which the Manufactured  Homes are located. It is a policy
of BankAmerica Housing Services to obtain title insurance policies 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. 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 securing Land-in-Lieu Contracts can be obtained. As a result,
no title insurance is obtained in respect of such Contracts.
 
    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 BankAmerica  Housing Services' management  believes
such  information to  be material,  any Prospectus  Supplement may  also include
additional information concerning the  related Contract Pool  that is stored  in
BankAmerica Housing Services' electronic data processing system.
 
    See  "The  Sellers"  herein for  a  description of  certain  origination and
underwriting  practices  of  BankAmerica   Housing  Services  with  respect   to
manufactured  housing contracts that have been originated by BankAmerica Housing
Services or purchased by BankAmerica Housing Services or SPFSC on an  individual
basis.  To the extent any Contracts in a  Contract Pool were purchased by one or
more of the  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.

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 December  31, 1995, Bank of America and  its
consolidated  subsidiaries accounted  for approximately 70%  of the consolidated

    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 BankAmerica Housing Services.  Bank
of  America expects that any Contracts it conveys to a Trust Fund will have been
originated or purchased by BankAmerica Housing Services on an individual  basis,
transferred by BankAmerica Housing Services to SPFSC (as further described 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 BankAmerica Housing Services,  SPFSC and Bank of America  in
the  foregoing  manner,  the  related Prospectus  Supplement  will  describe the
conveyances for  such  Contracts  from  such  Contracts'  origination  to  their
conveyance to the related Trust Fund.
 
SECURITY PACIFIC FINANCIAL SERVICES OF CALIFORNIA, INC.
 
    SPFSC  is a subsidiary of Bank of America  and an affiliate of BAFSB. In the
second  quarter  of  1994,  SPFSC  began  purchasing  certain  contracts  on  an
individual  basis from  BankAmerica Housing  Services. SPFSC's  headquarters are
located in San Diego, California (telephone 619-578-6150).
 
LOAN ORIGINATIONS
 
    BankAmerica Housing Services purchases  and originates manufactured  housing
contracts  on an  individual basis  through 38  regional offices  throughout the
United States,  serving 48  states. Through  its regional  offices,  BankAmerica
Housing  Services arranges to purchase manufactured housing contracts originated
by manufactured housing dealers located throughout the United States. Generally,
these purchases  result  from  BankAmerica  Housing  Services'  regional  office
personnel contacting dealers located in their regions and explaining BankAmerica
Housing  Services' 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'  investigation  of  the   dealer's
creditworthiness  and general business  reputation, BankAmerica Housing Services
and the dealer will enter into a dealer agreement. BankAmerica Housing  Services
also originates manufactured housing contracts directly with customers.
 
                                       20
<PAGE>
   
    Under  current laws and regulations applicable to federal savings banks such
as  BAFSB,  a  federal  savings  bank  cannot  maintain  in  its  portfolio  any
manufactured  housing contract that has  a term to maturity  of more than twenty
years or any manufactured  housing contract with respect  to which the  financed
amount  is greater than 90% of the  value of the manufactured home. Manufactured
housing contracts  that cannot  be maintained  in the  portfolio of  BankAmerica
Housing  Services  for  these reasons  are  currently  acquired by  SPFSC  on an
individual basis at or about the time such contracts are originated or purchased
by BankAmerica Housing  Services. Any such  contracts that constitute  Contracts
for  a Contract Pool will be purchased by Bank of America from SPFSC immediately
prior to Bank  of America's conveyance  of such Contracts  to the related  Trust
Fund. The foregoing circumstances may change if the relevant laws or regulations
are  modified to  permit the  investment by  federal savings  banks in contracts
having terms to maturity of more than twenty years or with respect to which  the
financed  amount is greater  than 90% of  the value of  the related manufactured
homes. The  documents of  title in  respect of  a Contract  sold by  BankAmerica
Housing  Services to SPFSC, then by SPFSC to Bank of America and then by Bank of
America to  any  Trust  Fund  will show  BankAmerica  Housing  Services  as  the
lienholder.  See "Risk Factors -- Security  Interests in the Manufactured Homes"
and "Certain  Legal  Aspects of  the  Contracts  -- Security  Interests  in  the
Manufactured  Homes" herein. If  any Contracts having terms  to maturity of more
than twenty years or with respect to  which the financed amount is greater  than
90%  of the value of the related  manufactured homes are not transferred between
BankAmerica Housing Services, SPFSC and Bank of America in the foregoing  manner
(or  if any  Contracts conveyed  by Bank  of America  to a  Trust Fund  were not
originated or purchased on an individual basis by BankAmerica Housing Services),
the related  Prospectus  Supplement  will  describe  the  conveyances  for  such
Contracts  from such Contracts'  origination to their  conveyance to the related
Trust Fund.
    
 
    In addition to purchasing and originating manufactured housing contracts  on
an  individual  basis,  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 BankAmerica
Housing Services), the portfolios of governmental agencies or  instrumentalities
or  the portfolios of other entities that purchase and hold manufactured housing
contracts. Moreover, BankAmerica  Housing Services,  on behalf  of other  owners
(including  SPFSC),  services  manufactured  housing  contracts  that  were  not
purchased  or  originated  by  BankAmerica  Housing  Services.  Currently,   the
servicing of all such contracts is, and BankAmerica Housing Services' management
currently  anticipates that servicing of all such contracts will continue to be,
performed through BankAmerica  Housing Services'  manufactured housing  regional
office  system. However, BankAmerica  Housing Services can  provide no assurance
that this will continue to be the case.
 
    BankAmerica  Housing  Services'  general   practices  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 BankAmerica Housing  Services'
servicing practices.
 
UNDERWRITING PRACTICES
 
    With  respect to each retail manufactured housing contract that is purchased
from a dealer,  BankAmerica Housing Services'  general practice 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.
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.  After  the
manufactured  home financed under such  contract is delivered and  set up by the
dealer, and the customer has moved  in, BankAmerica purchases the contract  from
the dealer.
 
    Because  manufactured  homes  generally  depreciate  in  value,  BankAmerica
Housing Services' 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, BankAmerica Housing
Services' underwriting guidelines generally require, and have required, regional
office personnel to
 
                                       21
<PAGE>
   
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 has developed certain guidelines
for employment  history and  debt-to-income ratios.  In the  case of  employment
history,  BankAmerica Housing  Services 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'  estimate of  the applicant's
after-tax income. Although BankAmerica Housing Services has guidelines for  some
of these criteria, BankAmerica Housing Services 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,  BankAmerica  Housing  Services'  management
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,  BankAmerica Housing  Services  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'  management.  BankAmerica  Housing  Services'  underwriting guidelines
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  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  BankAmerica  Housing
Services' headquarters, and modified as necessary.
    
 
    It  is the policy of BankAmerica Housing Services 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 BankAmerica Housing  Services 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 BankAmerica Housing  Services' 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. BankAmerica Housing Services 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  BankAmerica Housing  Services 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 BankAmerica Housing Services'
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 BankAmerica Housing Services) that,
 
                                       22
<PAGE>
   
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,  BankAmerica
Housing   Services  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  BankAmerica Housing  Services. However,
BankAmerica Housing Services 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  to finance no  more than the  lower of (i)  125% of the manufacturer's
invoice price plus  taxes, 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,  prepaid  financing
charges (points), 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 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  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 to
finance, with respect to new and used  manufactured homes, no more than 90%  or,
in  the case of manufactured housing contracts to  be held by SPFSC, 95%, of the
total buyer's cost of any manufactured home. Such buyer's cost includes  certain
fees,  prepaid  financing  charges  (points), sales  tax  and  certain insurance
premiums (including up to five years of premiums on required hazard  insurance).
In the case of new manufactured homes, the maximum amount financed cannot exceed
130%  of the manufacturer's  invoice price plus  taxes, freight charges, certain
dealer  installed  equipment  and  certain  set-up  costs.  BankAmerica  Housing
Services  also  has had  a policy  from May  1994  to July  1995 not  to finance
manufactured housing contracts for terms exceeding 20 years (or, in the case  of
certain  contracts held by SPFSC,  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 provided that  such contracts are sold to SPFSC at the
time of origination or purchase by BankAmerica Housing Services.
 
    BankAmerica Housing Services  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   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' management at its headquarters in San Diego and are applicable to  all
regional  offices in BankAmerica Housing Services' manufactured housing regional
office system.

SERVICING
 
   
    BankAmerica Housing  Services,  through its  manufactured  housing  regional
office  system,  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, BankAmerica  Housing  Services  will retain
servicing  responsibilities  with  respect  to  such  contracts.  In   addition,
BankAmerica  Housing  Services 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  BankAmerica  Housing  Services.  Generally,  such  servicing
responsibilities are,  and would  be, carried  out through  BankAmerica  Housing
Services'  manufactured  housing  regional  office  system.  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 BankAmerica Housing Services, 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,  if  deemed advisable  by  BankAmerica
Housing Services, 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, BankAmerica Housing Services'
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 and Loan Loss/Repossession  Experience"
below  and  "The  Seller(s)" in  the  Prospectus  Supplement for  any  Series of
Certificates offered hereby for certain historical statistical data relating  to
the  delinquency and repossession  experience of the  contracts serviced through
BankAmerica Housing  Services'  manufactured  housing  regional  office  system.

BANKAMERICA HOUSING SERVICES' 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  BankAmerica  Housing   Services'  manufactured   housing  contracts   are
originated  which have favorably  affected portfolio performance  in relation to
delinquencies, repossessions  and  loan  losses during  this  period.  Portfolio
performance  in these  respects has been  somewhat worse  in Southern California
than in other geographical areas. As of December 31, 1995, contracts related  to
manufactured homes located in Southern California represent 1.95% of BankAmerica
Housing  Services'  loan servicing  portfolio based  on the  aggregate principal
balance  of  the   contracts  being  serviced.   In  Southern  California,   the
delinquencies  as a percentage of contracts outstanding were 2.15% and 2.14%, as
of December 31, 1994 and December  31, 1995, respectively, as compared to  1.62%
and  2.17% for the portfolio  as a whole for  these periods. Losses on defaulted
contracts as a percentage of the aggregate principal balance of contracts  being
serviced  in  Southern  California for  these  periods were  11.60%  and 13.64%,
respectively, as compared  with 1.30% and  1.04% for the  portfolio as a  whole.
BankAmerica Housing Services' management believes that these differences reflect
the  adverse prevailing economic conditions  in Southern California during these
periods, including job losses and declines in real estate values. They also  may
in  part  result  from  different minimum  loan  underwriting  criteria  used in
underwriting loans in California prior to  July 1991. Prior to that date,  SPHSI
used    more   liberal    loan   underwriting   criteria    in   California   in
 
                                       26
<PAGE>
response to  the underwriting  practices of  competing lenders.  Although  these
standards  were used throughout California, only the portion of the portfolio in
Southern California  has  suffered  materially different  delinquency  and  loss
experience  than the rest  of the country.  The differing underwriting practices
for California were  discontinued in July  1991. Presently, BankAmerica  Housing
Services  is not actively originating contracts in Southern California. In 1993,
1994 and 1995,  loan originations in  Southern California were  less than 3%  of
total originations, based on the number of contracts.
 
    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. BankAmerica  Housing Services  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, BankAmerica  Housing  Services'
business  predecessor, and certain pools  of manufactured housing contracts sold
by BankAmerica Housing  Services, 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,   BankAmerica   Housing  Services'
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,   BankAmerica   Housing   Services'  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 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
 
                                       27
<PAGE>
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 5% 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 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.
 
    Unless  otherwise  specified in  the  applicable Prospectus  Supplement, the
yield to  holders of  any Class  of Certificates  will 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.
 
                                       28
<PAGE>
    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 any material provisions of
the Agreement relating to such Series  which differ materially from the form  of
the  Agreement filed as  an exhibit to the  Registration Statement. The material
differences will be described in the related Prospectus Supplement.  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
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.  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.)
 
                                       29
<PAGE>
    The Certificates of each Series will  evidence an interest, as specified  in
the  related Prospectus Supplement, in one or  more Trust Funds. 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,  BankAmerica Housing  Services 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, (iv) the proceeds  of
all  insurance policies  described herein and  (vii) if applicable,  one or more
forms of credit support.
 
    Bank  of  America,  BankAmerica  Housing  Services  or  both  of  them,   as
applicable,  will convey the Contracts to  the Trustee. See "The Contract Pools"
herein and "-- Conveyance of Contracts" below. 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, BankAmerica
Housing Services, Bank of  America, or both  of them will  sell to the  Trustee,
without  recourse, all right, title and interest of BankAmerica Housing Services
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,  the
BankAmerica Housing Services' 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,  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 or BankAmerica Housing
Services, 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  BankAmerica  Housing  Services,   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  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"
herein.
 
                                       30
<PAGE>
    Bank   of  America,  BankAmerica  Housing  Services  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, BankAmerica
Housing  Services or both of  them in connection with  the Contracts conveyed to
the related  Trust  Fund,  the  terms  pursuant to  which  Bank  of  America  or
BankAmerica  Housing  Services,  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 BankAmerica Housing Services 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.
 
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  and/or  interest  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
 
                                       31
<PAGE>
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.
 
   
    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)
 
                                       32
<PAGE>
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 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 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
 
                                       33
<PAGE>
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; 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 than 5%  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 pursuant to (1) above 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
 
                                       34
<PAGE>
   
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  together with  any shortfall  in interest  due to  such
Certificateholders   in  respect  of  prior  Distribution  Dates  (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.
 
   
    C.  TERMINATION  AUCTION.    If  specified  in  the  applicable   Prospectus
Supplement,  the Trustee for the  related Trust Fund shall  solicit bids for the
purchase at an auction (a "Termination  Auction") of the Contracts remaining  in
the  Trust Fund no  later than ninety  days following a  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.  In  the  event  that
satisfactory bids are received as described in the applicable Agreement, the net
sale proceeds will be  distributed to Certificateholders, in  the same order  of
priority  as collections received  in respect of  the Contracts. If satisfactory
bids are not received, the Trustee shall decline to sell the Contracts and shall
not be under any obligation to  solicit any further bids or otherwise  negotiate
any  further sale of the Contracts.  Under the applicable Agreement, the winning
bid must equal or exceed the Minimum Termination Amount. If an election has been
made to  treat the  related Trust  Fund as  a REMIC,  such sale  and  consequent
termination  of the related Trust Fund must constitute a "qualified liquidation"
of the Trust Fund under Section 860F of the Code, including the requirement that
the qualified  liquidation takes  place over  a period  not to  exceed 90  days.
(Section 10.01.)
    
 
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
 
                                       35
<PAGE>
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.)
 
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.)
 
    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 a  standard loss payee
clause in favor of the Servicer and its successors and assigns. In general,  the
Servicer will not be
    
 
                                       36
<PAGE>
   
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,
marshalling 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,
BankAmerica Housing Services (as well as any successor Servicer, if  BankAmerica
Housing  Services is not  the Servicer) or any  of their respective affiliates).
(Section 8.01.)
 
    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%
 
                                       37
<PAGE>
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.
 
    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
 
                                       38
<PAGE>
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  and/or  interest on  each  Distribution  Date from
amounts collected on the  related Contract Pool  that is prior  to the right  to
receive such
 
                                       39
<PAGE>
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 both  principal and  interest  (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 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  and  interest  in  accordance  with  the
    applicable distribution formula.
 
        2.   The distribution  formula for the  Senior 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  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  are entitled on particular Distribution
    Dates. If the holders of the Senior 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 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 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  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 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.
 
    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
 
                                       40
<PAGE>
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 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 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 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  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
 
                                       41
<PAGE>
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, BankAmerica Housing Services  or an affiliate thereof  may be a  Credit
Facility Provider.
    
 
    If  specified in  the applicable  Prospectus Supplement,  a Credit Facility,
rather than guaranteeing distributions of  particular amounts to the holders  of
Certificates  of particular Classes, may, instead, guarantee 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 Contracts or  of other amounts. The extent to  which
any  such collections are guaranteed under  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, BankAmerica Housing Services 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 discussion, which has been prepared and reviewed by Morrison &
Foerster  LLP,  special  counsel  to Bank  of  America  and  BankAmerica Housing
Services, is a general discussion of all anticipated material federal income tax
consequences of the  purchase, ownership and  disposition of Certificates.  This
discussion  is based on current provisions  of the Code, including Sections 860A
through 860G of the Code
    
 
                                       42
<PAGE>
and upon regulations, rulings  and decisions now  in effect, including  Treasury
Regulations  issued on December 23, 1992 (the "REMIC Regulations"), all of which
are subject  to change  or possibly  differing interpretations.  The  discussion
below  does not purport to deal with  the federal tax consequences applicable to
all categories  of  investorship (for  example,  life insurance  companies,  tax
exempt  organizations,  dealers  in  securities  and  taxpayers  subject  to the
alternative minimum  tax),  some of  which  may  be subject  to  special  rules.
Investors  should consult  their own  tax advisors  in determining  the federal,
state, local and any other tax  consequences to them of the purchase,  ownership
and disposition of Certificates. For purposes of this tax discussion (other than
the discussion of information reporting), references to a "Certificateholder" or
a "holder" mean the beneficial owner of a Certificate.
 
   
    With respect to any Series of Certificates, Morrison & Foerster LLP, special
counsel  to Bank of America and BankAmerica  Housing Services, is of the opinion
that the statements contained  in the discussion hereunder,  to the extent  they
constitute matters of law or legal conclusions with respect thereto, are correct
in  all material respects, under the assumptions stated therein and existing law
as of the date hereof.
    
 
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 made. Upon the issuance of each Series of Certificates
for which a REMIC election is made, Morrison & Foerster LLP, special counsel  to
Bank  of  America and  BankAmerica Housing  Services,  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 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").
 
    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)  "qualifying real  property  loans"
within  the meaning  of Section  593(d) of the  Code, (ii)  "real estate assets"
within the  meaning  of  Section  856(c)(5)(A) of  the  Code  and  (iii)  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)(5)(A) of the Code. The assets of the Trust Fund will include, in
addition to the Contracts, payments on the Contracts held pending  distribution,
 
                                       43
<PAGE>
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  593 of  the Code  define  a "qualifying  real property  loan" to
include a loan secured by manufactured housing that qualifies as a single family
residence under the Code, (ii) 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 (iii)  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 qualify 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  three foregoing sections  of the  Code.
However,  the REMIC Regulations provide that "permitted investments," as defined
below under  "--  B.  Qualification  as  a REMIC,"  will  be  considered  to  be
"qualifying  real property  loans" within the  meaning of Section  593(b) of the
Code and "real estate assets" within the meaning of Section 856(c)(5)(A) of  the
Code.  REMIC  Certificates  held by  a  real  estate investment  trust  will not
constitute  "Government  Securities"   within  the  meaning   of  Code   Section
856(c)(5)(A), and 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 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 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  BankAmerica Housing Services 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
 
                                       44
<PAGE>
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 two 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"),  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 separate elections  may be made  to
treat  segregated portions of  the assets of  a single Trust  Fund as REMICs for
federal income  tax  purposes  (respectively, the  "Subsidiary  REMIC"  and  the
"Master  REMIC"). Upon the issuance of any such series of Certificates, Morrison
& Foerster LLP, special tax counsel  to Bank of America and BankAmerica  Housing
Services, will have advised Bank of America and BankAmerica Housing Services, as
described  above,  that at  the  initial issuance  of  the Certificates  of such
Series, the Subsidiary REMIC and the Master  REMIC will each 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. Only REMIC  Certificates issued by the  Master REMIC will be
offered hereunder. 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," both REMICs in a
two-tier REMIC structure will 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. The Code, however, 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 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,
 
                                       45
<PAGE>
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.
 
    2. ORIGINAL  ISSUE  DISCOUNT.    Regular Certificates  may  be  issued  with
"original issue discount." Rules governing original issue discount are set forth
in  Sections 1271-1273 and 1275 of the  Code and the Treasury regulations issued
thereunder in January  1994 (the  "OID Regulations"). The  discussion herein  is
based  in part on the  OID Regulations. Although the  rules relating to original
issue discount contained in the Code were modified by the 1986 Act  specifically
to address the tax treatment of securities, such as the Regular Certificates, on
which principal is required to be prepaid based on prepayments of the underlying
assets,  regulations  under  that  legislation  have  not  yet  been  finalized.
Certificateholders also should be aware that the OID Regulations do not  address
certain   issues  relevant  to   prepayable  securities  such   as  the  Regular
Certificates.
 
    In general, in the  hands of the original  holder of a Regular  Certificate,
original  issue  discount,  if  any,  is  the  difference  between  the  "stated
redemption price at maturity" of the Regular Certificate and its "issue  price."
The  original  issue discount  with  respect to  a  Regular Certificate  will be
considered to be  zero if it  is less  than 0.25% of  the Regular  Certificate's
stated  redemption price at maturity multiplied  by the number of complete years
from the date of issue of such Regular Certificate to its maturity date. The OID
Regulations, however, provide a special DE MINIMIS rule to apply to  obligations
such  as the Regular Certificates  that have more than  one principal payment or
that have interest payments that are not qualified stated interest as defined in
the OID Regulations, payable before maturity ("installment obligations").  Under
the  special  rule,  original issue  discount  on an  installment  obligation is
generally considered to be zero if it is less than 0.25% of the principal amount
of the obligation multiplied by the weighted average maturity of the  obligation
as defined in the OID Regulations. Because of the possibility of prepayments, it
is  not clear  whether or  how the DE  MINIMIS rules  will apply  to the Regular
Certificates. It is possible that the anticipated rate of prepayments assumed in
pricing the debt instrument (the "Assumed Prepayment Rate") will be required  to
be   used  in  determining   the  weighted  average   maturity  of  the  Regular
Certificates. In  the absence  of  authority to  the  contrary, and  unless  the
related Prospectus Supplement otherwise provides, it is expected that each Trust
Fund  as  to which  a REMIC  election is  made  will apply  the DE  MINIMIS rule
applicable to installment obligations by using the Assumed Prepayment Rate.  The
OID  Regulations provide  a further  special DE  MINIMIS rule  applicable to any
Regular Certificates that are  "self-amortizing installment obligations,"  I.E.,
Regular  Certificates that provide for equal  payments composed of principal and
qualified stated interest payable unconditionally  at least annually during  its
entire  term, with no significant additional payment required at maturity. Under
this special  rule, original  issue discount  on a  self-amortizing  installment
obligation  is generally considered to be zero if  it is less than 0.167% of the
principal amount of the  obligation multiplied by the  number of complete  years
from the date of issue of such a Regular Certificate to its maturity date.
 
    Generally,  the original holder of a  Regular Certificate that includes a DE
MINIMIS amount of original issue discount includes that original issue  discount
in  income as principal  payments are made.  The amount included  in income with
respect to each principal payment equals a pro rata portion of the entire amount
of DE MINIMIS original issue discount with respect to that Regular  Certificate.
Any  DE MINIMIS amount of original issue discount included in income by a holder
of a Regular Certificate is generally treated  as a capital gain if the  Regular
Certificate  is a capital asset in the  hands of the holder thereof. Pursuant to
the OID Regulations, a  holder of a Regular  Certificate may, however, elect  to
include  in gross  income all  interest that  accrues on  a Regular Certificate,
including any DE MINIMIS original issue  discount and market discount, by  using
the  constant  yield  method  described below  with  respect  to  original issue
discount.
 
    The stated redemption price at  maturity of a Regular Certificate  generally
will  be equal to the  sum of all payments,  whether denominated as principal or
interest,  to  be  made  with  respect  thereto  other  than  "qualified  stated
interest."  Pursuant to the OID Regulations, qualified stated interest is stated
interest that is  unconditionally payable at  least annually at  a single  fixed
rate  of interest (or, under  certain circumstances, a variable  rate tied to an
objective index) during the  entire term of  the Regular Certificate  (including
short  periods). It is  possible that the  Service could assert  that the stated
rate of interest on the Certificates is not
 
                                       46
<PAGE>
unconditionally  payable  or  otherwise  does not  qualify  as  qualified stated
interest.  Such  position,   if  successful,  would   require  all  holders   of
Certificates to accrue all income on the Certificates under the OID Regulations.
Unless  otherwise noted in the applicable  Prospectus Supplement, and unless the
related Prospectus Supplement otherwise provides, it is expected that each Trust
Fund as to which a REMIC election is made will treat all stated interest on  the
Certificates  as qualified stated  interest. Under the  OID Regulations, certain
variable interest rates payable on  Regular Certificates, including rates  based
upon  the weighted  average interest rate  of Contracts in  the related Contract
Pool, may not be  treated as qualified  stated interest. In  such case, the  OID
Regulations  would treat interest under such  rates as contingent interest which
generally must be included in income  by the Regular Certificateholder when  the
interest becomes fixed, as opposed to when it accrues. Until further guidance is
issued   concerning  the   treatment  of   such  interest   payable  on  Regular
Certificates, unless otherwise  noted in the  applicable Prospectus  Supplement,
the REMIC will treat such interest as being payable at a variable rate tied to a
single  objective index  of market  rates. Prospective  investors should consult
their tax  advisors regarding  the  treatment of  such  interest under  the  OID
Regulations.  In  the absence  of  authority to  the  contrary and  if otherwise
appropriate, and unless the related Prospectus Supplement otherwise provides, it
is expected that  each Trust  Fund as  to which a  REMIC election  is made  will
determine  the stated redemption  price at maturity of  a Regular Certificate by
assuming that  the anticipated  rate  of prepayment  for  all Contracts  in  the
related  Contract Pool will occur in such a manner that the initial Pass-Through
Rate for a  Certificate will not  change. Accordingly, interest  at the  initial
Pass-Through  Rate  will  constitute  qualified  stated  interest  payments  for
purposes of applying  the original  issue discount  provisions of  the Code.  In
general,  the issue price of a Regular Certificate in a Class is the first price
at which a substantial amount of the Regular Certificates of such Class are sold
for money to the  public (excluding bond houses,  brokers or similar persons  or
organizations  acting  in  the  capacity of  underwriters,  placement  agents or
wholesalers).  If  a  portion  of  the  initial  offering  price  of  a  Regular
Certificate  is allocable  to interest  that has  accrued prior  to its  date of
issue, the issue price of such a Regular Certificate includes that  pre-issuance
accrued interest.
 
    Where the interval between the issue date and the first Distribution Date on
a   Regular  Certificate  is   longer  than  the   interval  between  subsequent
Distribution Dates, the greater of any original issue discount (disregarding the
rate in the first period) and any  interest foregone during the first period  is
treated  as the amount by  which the stated redemption  price at maturity of the
Certificate exceeds  its  issue  price  for purposes  of  the  DE  MINIMIS  rule
described  above. The OID Regulations suggest that  all interest on a long first
period Regular Certificate  that is  issued with non-DE  MINIMIS original  issue
discount,  as determined under  the foregoing rule, will  be treated as original
issue discount.  Where  the  interval  between the  issue  date  and  the  first
Distribution  Date on a Regular Certificate is shorter than the interval between
subsequent Distribution Dates, interest  due on the  first Distribution Date  in
excess  of the amount that accrued during the first period would be added to the
Certificates' stated redemption  price at  maturity. Regular  Certificateholders
should  consult their own tax  advisors to determine the  issue price and stated
redemption price at maturity of a Regular Certificate.
 
    If the Regular Certificates are determined to be issued with original  issue
discount,  a holder of a Regular Certificate must generally include the original
issue discount in ordinary  gross income for federal  income tax purposes as  it
accrues  in advance of the receipt of  any cash attributable to such income. The
amount of original issue discount, if any, required to be included in a  Regular
Certificateholder's ordinary gross income for federal income tax purposes in any
taxable year will be computed in accordance with Section 1272(a) of the Code and
the  OID Regulations. Under such Section and the OID Regulations, original issue
discount accrues on a daily basis under a constant yield method that takes  into
account the compounding of interest. The amount of original issue discount to be
included  in  income  by  a holder  of  a  debt instrument,  such  as  a Regular
Certificate, under  which  principal payments  may  be subject  to  acceleration
because  of prepayments of other debt  obligations securing such instruments, is
computed by taking into account the Assumed Prepayment Rate.
 
    The amount of original issue  discount included in income  by a holder of  a
Regular  Certificate is the  sum of the  "daily portions" of  the original issue
discount for each  day during  the taxable  year on  which the  holder held  the
Regular   Certificate.  The  daily  portions  of  original  issue  discount  are
determined by allocating to
 
                                       47
<PAGE>
each day in any "accrual  period" a PRO RATA portion  of the excess, if any,  of
the  sum of (i)  the present value of  all remaining payments to  be made on the
Regular Certificate  as  of the  close  of the  "accrual  period" and  (ii)  the
payments  during  the  "accrual  period"  of  amounts  included  in  the  stated
redemption price of the Regular Certificate  over the "adjusted issue price"  of
the Regular Certificate at the beginning of the "accrual period." Generally, the
"accrual  period" for the  Regular Certificates corresponds  to the intervals at
which amounts are paid or compounded  with respect to such Regular  Certificate,
beginning  with their date  of issuance and  ending with the  maturity date. The
"adjusted issue price" of a Regular Certificate at the beginning of any  accrual
period  is the sum  of the issue  price and accrued  original issue discount for
each prior accrual period reduced by the amount of payments other than  payments
of  qualified stated  interest made during  each prior accrual  period. The Code
requires the present  value of the  remaining payments to  be determined on  the
bases  of  (a)  the original  yield  to  maturity (determined  on  the  basis of
compounding at the close  of each accrual period  and properly adjusted for  the
length  of the accrual period), (b)  events, including actual prepayments, which
have occurred before  the close of  the accrual period,  and (c) the  assumption
that the remaining payments will be made in accordance with the original Assumed
Prepayment  Rate.  The effect  of this  method  is to  increase the  portions of
original issue discount that a Regular Certificateholder must include in  income
to  take into account  prepayments on Contracts  held by the  related Trust Fund
that occur at a rate  that exceeds the Assumed  Prepayment Rate and to  decrease
(but not below zero for any period) the portions of original issue discount that
a  Regular  Certificateholder  must  include  in  income  to  take  into account
prepayments made on  Contracts that  occur at  a rate  that is  slower than  the
Assumed  Prepayment Rate. Although  original issue discount  will be reported to
Regular  Certificateholders   based  on   the   Assumed  Prepayment   Rate,   no
representation  is made to Regular Certificateholders that the Contracts held by
the related Trust Fund will be prepaid at that rate or at any other rate.
 
    A subsequent purchaser  of a Regular  Certificate also will  be required  to
include  in  such  purchaser's  ordinary gross  income  for  federal  income tax
purposes the original  issue discount,  if any,  accruing with  respect to  such
Regular  Certificate, unless  the price  paid equals or  exceeds the  sum of all
amounts payable  on the  Regular Certificate  other than  payments of  qualified
stated interest. If the price exceeds the sum of the Regular Certificate's issue
price  plus the aggregate amount of original issue discount accrued with respect
to the Regular Certificate, but does not equal or exceed the sum of all  amounts
payable  on  the Regular  Certificate other  than  payments of  qualified stated
interest, the amount of original issue discount to be accrued will be reduced in
accordance with a formula set forth in Section 1272(a)(7)(B) of the Code.
 
    Bank of America and BankAmerica Housing Services believe, upon the advice of
Morrison & Foerster LLP, special tax counsel to Bank of America and  BankAmerica
Housing  Services, that  the holder  of a  Regular Certificate  determined to be
issued with non-DE MINIMIS original issue  discount will be required to  include
the  original issue  discount in  ordinary gross  income for  federal income tax
purposes computed in the  manner described above.  However, the OID  Regulations
either  do not address or are subject to varying interpretations with respect to
several issues  concerning  the  computation  of  original  issue  discount  for
obligations such as the Regular Certificates.
 
    3.  VARIABLE  RATE  REGULAR  CERTIFICATES.   Regular  Certificates  may bear
interest at  a variable  rate. Under  the OID  Regulations, if  a variable  rate
Regular  Certificate provides for qualified stated interest payments computed on
the basis  of certain  qualified floating  rates or  objective rates,  then  any
original  issue discount on  such a Regular Certificate  is computed and accrued
under the same methodology that applies to Regular Certificates paying qualified
stated interest at a fixed rate. See the discussion above under "-- 2.  Original
Issue  Discount." Accordingly, if the issue  price of such a Regular Certificate
is equal to  its stated redemption  price at maturity,  the Regular  Certificate
will not have any original issue discount.
 
    For purposes of applying the original issue discount provisions of the Code,
all or a portion of the interest payable with respect to a variable rate Regular
Certificate  may  not  be  treated  as  qualified  stated  interest  in  certain
circumstances, including the following: (i) if the variable rate of interest  is
subject  to one or more minimum or maximum rate floors or ceilings which are not
fixed throughout the term  of the Regular Certificate  and which are  reasonably
expected as of the issue date to cause the rate in certain accrual periods to be
significantly  higher or lower  than the overall expected  return on the Regular
Certificate determined without such floor or  ceiling; (ii) if it is  reasonably
expected    that   the   average    value   of   the    variable   rate   during
 
                                       48
<PAGE>
the  first  half  of  the  term  of  the  Regular  Certificate  will  be  either
significantly  less than or significantly greater  than the average value of the
rate during the final half of the  term of the Regular Certificate; or (iii)  if
interest  is not payable in  all circumstances. In these  situations, as well as
others, it is unclear under the  OID Regulations whether such interest  payments
constitute qualified stated interest payments, or must be treated either as part
of  a Regular  Certificate's stated  redemption price  at maturity  resulting in
original issue discount, or represent  contingent payments which are  recognized
as  ordinary gross income for  federal income tax purposes  only as the interest
payments become fixed in each accrual period.
 
    If a variable rate  Regular Certificate is deemed  to have been issued  with
original  issue  discount,  as described  above,  the amount  of  original issue
discount accrues on a daily basis under a constant yield method that takes  into
account  the  compounding  of  interest; provided,  however,  that  the interest
associated with  such  a Regular  Certificate  generally is  assumed  to  remain
constant  throughout the term of the Regular  Certificate at a rate that, in the
case of a qualified floating rate,  equals the value of such qualified  floating
rate  as of the  issue date of  the Regular Certificate,  or, in the  case of an
objective rate,  at a  fixed rate  that reflects  the yield  that is  reasonable
expected  for the  Regular Certificate. A  holder of such  a Regular Certificate
would then recognize original issue discount during each accrual period which is
calculated based  upon such  Regular Certificate's  assumed yield  to  maturity,
adjusted to reflect the difference between the assumed and actual interest rate.
 
    The  OID  Regulations  either  do  not address  or  are  subject  to varying
interpretations with respect  to several  issues concerning  the computation  of
original  issue  discount with  respect to  the Regular  Certificates, including
variable rate Regular Certificates. Additional information regarding the  manner
of  reporting  original issue  discount to  the  Service and  to the  holders of
variable  rate  Regular  Certificates  will  be  set  forth  in  the  Prospectus
Supplement relating to the issuance of such Regular Certificates.
 
    4.  PREMIUM.  A holder of a  Regular Certificate that purchases such Regular
Certificate at  a cost  (net of  accrued interest)  greater than  its  remaining
stated  redemption price at  maturity will be considered  to have purchased such
Regular Certificate at  a premium equal  to the  excess of such  cost over  such
remaining  stated redemption price, and  may, under Section 171  of the Code, if
the holder holds the Regular Certificate  as a capital asset within the  meaning
of  Section 1221 of  the Code, elect  to amortize such  premium under a constant
yield method over the  life of the Regular  Certificate. Although not free  from
doubt,  the Assumed Prepayment Rate should  be taken into account in determining
the life of the Regular Certificate for this purpose. Such amortized premium  is
generally  treated  as an  offset to  the  amount of  interest income  from such
Regular Certificate, rather than as  a separate interest deduction. An  election
made  by a  holder under Section  171 of the  Code would generally  apply to the
premium on all debt instruments  held for investment by  the holder at any  time
after  the beginning of the taxable year  in which such election is made, unless
the election is revoked with the Service's consent.
 
    5. MARKET  DISCOUNT.   A purchaser  of  a Regular  Certificate may  also  be
subject to the market discount rules. Market discount is generally the excess of
(i)  in the case of  a Regular Certificate issued  with original issue discount,
the revised issue price,  or (ii) in  the case of  a Regular Certificate  issued
without  original issue discount, its principal balance, over the holder's basis
in such Regular Certificate. Such purchaser will recognize gain upon receipt  of
a  principal distribution on the Regular  Certificate, whether it is received on
the date on which such  payment is scheduled to be  made or as a prepayment.  In
particular,  the holder will be required to allocate that principal distribution
first to the portion of the market discount on such Regular Certificate that has
accrued, but has  not previously  been included  in income,  and will  recognize
ordinary  income to that extent. In general  terms, market discount on a Regular
Certificate may be treated, at the  holder's election, as accruing under  either
(i)  a constant  yield method  or (ii)  in proportion  to remaining  accruals of
original issue  discount  (or,  if  there is  no  original  issue  discount,  in
proportion  to  remaining accruals  of interest  at the  applicable Pass-Through
Rate), in  each case  taking  into account  the  Assumed Prepayment  Rate.  Such
purchaser  also generally will be  required to treat a portion  of any gain on a
sale or exchange of the Regular Certificate as ordinary income to the extent  of
the  discount accrued, but unrecognized, to the date of disposition under one of
the   foregoing   methods.   As   an    alternative   to   the   inclusion    of
 
                                       49
<PAGE>
market  discount  in income  on the  foregoing  basis, the  holder may  elect 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. Such  an
election may be revoked only with the consent of the Secretary of the Treasury.
 
    In  addition,  deductions for  a  portion of  a  Regular Certificateholder's
interest expense  on any  debt incurred  or  continued to  purchase or  carry  a
Regular Certificate purchased with market discount may be deferred. The deferred
portion  of any interest  deduction would not  exceed the portion  of the market
discount on such  Regular Certificate that  accrues during the  taxable year  in
which  such  interest  would otherwise  be  deductible, and  generally  would be
deductible when such market  discount is included in  income, upon receipt of  a
principal  distribution on, or  sale of, such  Regular Certificate. The interest
deferral rule will not apply if  the Certificateholder elects to include  market
discount  in income currently as it accrues, as described above. Each Trust Fund
for which a REMIC election is made will report annually to certain categories of
its Regular Certificateholders and the Service information necessary to  compute
accruals of market discount.
 
    Notwithstanding  the above rules,  market discount on  a Regular Certificate
will be  considered to  be zero  if  such discount  is less  than 0.25%  of  the
remaining principal amount (or, in the case of a Regular Certificate issued with
original  issue discount, the remaining stated  redemption price at maturity) of
the Regular Certificate multiplied by  its weighted average remaining  maturity.
The  weighted average remaining  maturity of the  Regular Certificate presumably
would be  calculated  in a  manner  similar  to the  weighted  average  maturity
described  above  under "--  2. Original  Issue  Discount," taking  into account
distributions (including  distributions of  prepayments) prior  to the  date  of
acquisition  of such Regular Certificate by the  holder. If market discount on a
Regular Certificate is considered to be zero under this rule, the actual  amount
of  such discount must be allocated  to the remaining principal distributions on
such Regular Certificate and when each such distribution is received, gain equal
to the  discount allocated  to such  distribution will  be recognized.  Treasury
regulations implementing the market discount rules have not yet been issued, and
therefore  investors should  consult with their  own tax  advisors regarding the
application of these  rules as well  as the  advisability of making  any of  the
elections with respect thereto.
 
    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 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 and  by  any
amortized premium. Except as described above with respect to under "-- 5. 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, and will be  long term or short  term depending upon whether the
Regular Certificate has been held for more than one year.
 
                                       50
<PAGE>
    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 BankAmerica  Housing Services, 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 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,
partnership, or other entity organized in or under the laws of the United States
or a political subdivision thereof  or (iii) an estate  or trust, the income  of
which  is included in gross income for  United States tax purposes regardless of
its source.  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 BankAmerica Housing
 
                                       51
<PAGE>
Services and does not own actually or  constructively 10% or more of the  voting
stock  of Bank of America  or BankAmerica Housing Services.  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  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
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 BankAmerica Housing Services. 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. 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.  REPORTING  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.
 
    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. GENERAL.  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.
 
                                       52
<PAGE>
    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 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  Certificates,
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. DISTRIBUTIONS.  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"). 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.
 
                                       53
<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. Such aggregate basis
will be allocated first to cash and cash equivalents held by the Trust Fund  and
then  among  the individual  Contracts and  other  assets of  the Trust  Fund in
proportion to  their  respective  fair  market values.  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 fair
market value  of  that  Certificate at  the  time  of issuance.  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 basis of the Trust Fund 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 also may
be greater in  earlier years  because the  REMIC will  use a  constant yield  in
computing  income from  the Contracts  and 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 Classes
are paid.  This  method of  taxation  of  Residual Certificates  can  produce  a
significantly less favorable after-tax return for a Residual Certificate than if
it were taxed as a debt instrument.
 
    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,
and,  as described above, the  issue price of the  Residual Certificates will be
added to the issue price of Regular Certificates in determining the Trust Fund's
initial basis in its assets. Such recovery of basis by the Trust Fund will  have
the
 
                                       54
<PAGE>
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-THRU" 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  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. PROHIBITED 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) qualified (complete)  liquidation,
(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.  The
Trust  Fund  will be  subject  to a  tax  equal to  100%  of the  amount  of any
contributions of property made to the Trust
 
                                       55
<PAGE>
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,  with an exception for certain  thrift institutions, be subject to federal
income tax  in all  events. (Excess  inclusions are  defined below.)  Thus,  for
example,  an excess inclusion (i) may not, except with respect to certain thrift
institutions, 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
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.
 
    As  discussed above, thrift  organizations to which Section  593 of the Code
applies are excepted from  the general rule that  excess inclusions are, in  all
events,  subject  to taxation.  However, the  REMIC Regulations  prohibit thrift
institutions from offsetting their excess  inclusions with unrelated losses  and
net  operating  loss  carryovers  if  such  Residual  Certificates  do  not have
"significant value." A  Residual Certificate  has significant value  if (i)  the
aggregate  of the issue prices  of the Residual Certificates  in the REMIC is at
least 2%  of the  aggregate of  the issue  prices of  all Residual  and  Regular
Certificates  of the REMIC  and (ii) the "anticipated  weighted average life" of
the Residual Certificate (as defined below) is at least 20% of the  "anticipated
life  of the REMIC" (as defined below). The anticipated weighted average life of
the Residual Certificates is  based on all anticipated  payments to be  received
with  respect  thereto  (using  the Assumed  Prepayment  Rate).  The anticipated
weighted average life of  the REMIC is the  weighted average of the  anticipated
weighted  average lives  of all Classes  of Certificates in  the REMIC (computed
using all  anticipated payments  on a  Regular Certificate  with nominal  or  no
principal). Finally, an ordering rule under the
 
                                       56
<PAGE>
REMIC  Regulations provides that a thrift institution may only offset its excess
inclusion income  with deductions  after  it has  first applied  its  deductions
against  income  that  is  not  excess  inclusion  income.  If  applicable,  the
Prospectus Supplement  with respect  to  a Series  will  set forth  whether  the
related Residual Certificates are expected to have "significant value."
 
    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  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  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
 
                                       57
<PAGE>
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.
 
    The Conference Committee  Report to the  1986 Act provides  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.   The REMIC Regulations would disregard
certain transfers of Residual Certificates,  in which case the transferor  would
continue  to be treated as the owner of the Residual Certificates and thus would
continue to be subject to tax on its allocable portion of the net income of  the
REMIC.  Under  the  REMIC Regulations,  a  transfer of  a  "noneconomic residual
interest" (as defined below) to a Residual Holder 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. 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."
 
                                       58

    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 person that is a Foreign Holder (as  defined
above  in "C. Taxation of Regular Certificates -- 9. Taxation of Certain Foreign
Investors"). See  "Restrictions  on  Transfer of  REMIC  Residual  Certificates"
below. With respect to permitted transfers, Residual Certificateholders that are
Foreign  Holders 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 subject to 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.
 
    14. MARK-TO-MARKET OF  RESIDUAL CERTIFICATES.   Prospective purchasers of  a
Residual  Certificate  should be  aware  that, under  proposed  regulations (the
"Proposed Mark-to-Market Regulations"),  a Residual  Certificate acquired  after
January   3,  1995  cannot  be  marked-to-market.  The  Proposed  Mark-to-Market
Regulations  change  the   temporary  regulations  which   allowed  a   Residual
Certificate  to be marked-to-market provided that  it was not a "negative value"
residual interest  and did  not have  the same  economic effect  as a  "negative
value" residual interest. Prospective purchasers of a REMIC Residual Certificate
should  consult their  tax advisors  regarding the  possible application  of the
Temporary  Mark-to-Market  Treasury  Regulations  and  Proposed   Mark-to-Market
Treasury Regulations to REMIC Residual Certificates.
 
    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
 
                                       59
<PAGE>
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,  Morrison &
Foerster LLP,  special  counsel  to  Bank of  America  and  BankAmerica  Housing
Services,  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, 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 BankAmerica  Housing  Services would  be  able to  sell  or
otherwise dispose of any subordinated Non-REMIC
 
                                       60
<PAGE>
Certificates.  Accordingly,  Bank of  America  and BankAmerica  Housing Services
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  --  5.  Market  Discount"  and  "REMIC
Certificates -- C. Taxation of Regular Certificates -- 4. Premium."
 
    B. STATUS OF CERTIFICATES AS REAL PROPERTY LOANS.  In general, the Non-REMIC
Certificates, other  than "Premium  Non-REMIC Certificates"  (as defined  below)
will  be  (i) "qualifying  real property  loans" within  the meaning  of Section
593(d) of the  Code, (ii)  "real estate assets"  within the  meaning of  Section
856(c)(5)(A) of the Code and (iii) 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  includible 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 Treasury Regulations under Section 593 of
the Code define a "qualifying real property loan" to include a loan secured by a
mobile  home unit  "permanently fixed to  real property." 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 fixed" or permanently installed for purposes of Sections 593 or
856 of the Code would  depend on the facts and  circumstances of each case.  The
Treasury  Regulations under Section 593 of the  Code provide, by way of example,
that a mobile home unit is permanently  fixed to real property if, except for  a
brief  period in which the unit is transported  to its site, such unit is placed
on a foundation at a site with  wheels and axles removed, affixed to the  ground
by  means of straps, and connected to water, sewer, gas and electric facilities.
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 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.  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.
 
    Under the  stripped bond  rules, 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
 
                                       61
<PAGE>
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.  It  is unclear  whether these  rules would  be applicable  to the
Non-REMIC Certificates in the  absence of such regulations  or whether use of  a
reasonable  prepayment assumption may be  required or permitted without reliance
on these rules. It is also  uncertain, if a reasonable prepayment assumption  is
used,  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  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  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 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
 
                                       62
<PAGE>
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  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."
 
                                       63
<PAGE>
                                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
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  plans  subject  to  ERISA
("Plans")  and  on  persons having  certain  specified relationships  to  a Plan
("Parties in Interest") with respect to such Plans, including, for this purpose,
 
                                       64
<PAGE>
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 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 (Labor Reg.
Section  2510.3-101).  Under  these  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. However, the regulations
provide that, generally, the assets of  a corporation or partnership in which  a
Plan  invests 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  Labor  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.
 
    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 might
be a prohibited transaction under ERISA Sections  406 and 407 and subject to  an
excise  tax under Section 4975 of the  Code unless a statutory or administrative
exemption applies.
 
    In  Prohibited  Transaction  Exemption  83-1  ("PTE  83-1"),  which  amended
Prohibited  Transaction Exemption 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.
PTE  83-1  permits,  subject  to certain  conditions,  transactions  which might
otherwise be prohibited between  Plans and Parties in  Interest with respect  to
those  Plans related to the origination, maintenance and termination of mortgage
pools consisting of mortgage loans secured by first or second mortgages or deeds
of trust on single-family residential property, and the acquisition and  holding
of  certain mortgage pool pass-through  certificates representing an interest in
such mortgage pools by Plans. If the general conditions (discussed below) of PTE
83-1 are  satisfied,  investments  by  a Plan  in  certificates  that  represent
interests  in a mortgage pool  consisting of single family  loans will be exempt
from the prohibitions of  ERISA Sections 406(a) and  407 (relating generally  to
transactions  with  Parties in  Interest who  are not  fiduciaries) if  the Plan
purchases those  certificates at  no more  than fair  market value  and will  be
exempt  from  the prohibitions  of ERISA  Sections  406(b)(1) and  (2) (relating
generally to transactions  with fiduciaries)  if, in addition,  the purchase  is
approved  by an independent fiduciary,  no sales commission is  paid to the pool
sponsor, the Plan does  not purchase more  than 25% of  all certificates of  the
like  class, and at least 50% of  all such certificates are purchased by persons
independent of the pool sponsor  or pool trustee. PTE  83-1 does not provide  an
exemption for transactions involving subordinate certificates of the like class.
Accordingly,  unless otherwise provided in the related Prospectus Supplement, no
transfer of a subordinate certificate may be made to a Plan.
 
                                       65
<PAGE>
    PTE 83-1 sets forth three general conditions which must be satisfied for any
transaction to be  eligible for exemption:  (i) the maintenance  of a system  of
insurance  or  other  protection  for the  pooled  mortgage  loans  and property
securing such loans, and for indemnifying certificateholders against  reductions
in  pass-through payments due to property damage or defaults in loan payments in
an amount not less than  the greater of one  percent of the aggregate  principal
balance  of all covered  pooled mortgage loans  or the principal  balance of the
largest covered pooled mortgage loan; (ii)  the existence of a pool trustee  who
is not an affiliate of the pool sponsor; and (iii) a limitation on the amount of
the  payment retained by the pool sponsor,  together with other funds inuring to
its benefit, to not  more than adequate consideration  for selling the  mortgage
loans  plus reasonable compensation for services provided by the pool sponsor to
the mortgage pool.
 
    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 whether the first and third general conditions, and the
specific conditions described briefly  in the preceding  paragraph, of PTE  83-1
have  been  satisfied,  or  as  to  the  availability  of  any  other prohibited
transaction exemptions. 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 the exemptions described in  the DOL regulation 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 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 which proposes to  cause a Plan to purchase Certificates
should consult with their counsel concerning  the impact of ERISA and the  Code,
the  applicability of PTE 83-1 and  the potential consequences in their specific
circumstances, prior to  making such investment.  Moreover, each Plan  fiduciary
should  determine whether, under  the general fiduciary  standards of investment
procedure 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
 
    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,  BankAmerica   Housing  Services'   or  any   lender's  interest   in
manufactured  housing contracts. See "--  Security Interests 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 IN THE MANUFACTURED HOMES
 
    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   nontitle   states,  perfection   pursuant   to  the   provisions   of
 
                                       66
<PAGE>
the  UCC is required. Generally, with  respect to manufactured housing contracts
individually originated or purchased by BankAmerica Housing Services (for itself
or as agent for any affiliate of BankAmerica Housing Services that purchases any
such contracts  from  BankAmerica Housing  Services)  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 BankAmerica  Housing Services 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), BankAmerica Housing Services (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 BankAmerica  Housing Services'  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, BankAmerica
Housing Services  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.
 
    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, BankAmerica Housing Services  or both of them is subject  to
the  federal bankruptcy code, sells Contracts  to Bank of America or BankAmerica
Housing Services 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.
 
    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  BankAmerica Housing
Services 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
BankAmerica Housing Services 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
 
                                       67
<PAGE>
favor  of BankAmerica Housing Services 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.
BankAmerica Housing Services 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, BankAmerica
Housing Services would receive notice of  surrender if its security interest  in
the  manufactured  home  is  noted on  the  certificate  of  title. Accordingly,
BankAmerica Housing  Services  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,  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,  BankAmerica  Housing  Services  must
surrender possession of the certificate of title or BankAmerica Housing Services
will  receive  notice  as  a  result of  its  lien  noted  thereon; accordingly,
BankAmerica Housing Services 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  nontitle  states  where  perfection of  such  security  interest  is
achieved by appropriate filings under the UCC (as in effect in such state).
 
   
    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
BankAmerica  Housing Services 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 BankAmerica  Housing
Services  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,  BankAmerica Housing  Services, 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 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.
 
                                       68
<PAGE>
    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
BankAmerica Housing Services' ability to  repossess and resell any  Manufactured
Home or enforce a deficiency judgment.
 
LAND HOME AND LAND-IN-LIEU CONTRACTS
 
    Unless  otherwise  specified in  the  applicable Prospectus  Supplement, the
related Contract  Pool will  not  contain Land  Home Contracts  or  Land-in-Lieu
Contracts.  To the extent Land Home  Contracts or Land-in-Lieu Contracts or both
are contained  in any  Contract  Pool, the  related Prospectus  Supplement  will
include a discussion of legal issues relating to the transfer of such contracts,
and  the  related  security  interest  in  the  property  on  which  the related
Manufactured Home is located, to the Trust, and to the enforcement of the rights
of secured parties with respect to such 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 Servicer  on
behalf  of the  Trustee, as Bank  of America's or  BankAmerica Housing Services'
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 BankAmerica Housing
Services  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  BankAmerica  Housing  Services  has not
consented. Under the Agreement for a Series of
 
                                       69
<PAGE>
Certificates (unless otherwise specified in the related Prospectus  Supplement),
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.
 
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.
BankAmerica  Housing  Services  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
 
                                       70

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.
 
    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, BankAmerica
Housing Services 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 BankAmerica  Housing Services, 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 BankAmerica Housing
Services by Morrison & Foerster LLP, Irvine, California.
    
 
                              OTHER CONSIDERATIONS
 
    As federally insured depository institutions, Bank of America and BAFSB  (of
which BankAmerica Housing Services is an unincorporated division) 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 BAFSB, the receiver
or conservator could prevent the termination of BankAmerica Housing Services  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, the appointment of a
receiver  or  conservator  for BAFSB  could  result  in a  delay  or  possibly a
reduction in  payments on  the Certificates  to the  extent BankAmerica  Housing
Services  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, BAFSB or both of
them, a conservator or  receiver, as the case  may be, could recharacterize  the
sale of Contracts by Bank of America or BankAmerica Housing Services, 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 BAFSB.
 
    Similar consequences could result from a bankruptcy proceeding instituted by
or in respect of any affiliate of Bank of America or BAFSB that sells  Contracts
to  Bank  of America  or  BAFSB 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.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    1. BANK OF AMERICA NATIONAL TRUST AND SAVINGS ASSOCIATION
 
    Article   IX  of  the  Bylaws  of  ("Bank  of  America")  provides  for  the
indemnification of the directors, officers and employees of Bank of America,  or
persons  serving  at the  request of  Bank  of America  as a  director, officer,
employee or agent of another corporation  or other business entity, to the  full
extent  provided by the Delaware General Corporation  Law, as such law exists or
may hereafter  be  amended.  This indemnification  applies  to  any  threatened,
pending  or  completed action,  suit  or proceeding,  whether,  civil, criminal,
administrative or investigative.
 
    Indemnification  may  include  all  expenses  (including  attorneys'   fees,
judgments,  fines, ERISA excise taxes and amounts paid in settlement) reasonably
incurred by the indemnified person. However,  Bank of America is not  authorized
to   indemnify  against  expenses,  penalties  or  other  payments  incurred  in
administrative proceeding or action instituted by a bank regulatory agency which
proceedings or action  result in  a final  order against  such person  assessing
civil  money penalties or requiring payments to Bank of America. Bank of America
is authorized to advance expenses  incurred by an indemnified director,  officer
or  employee PROVIDED, if the Delaware General Corporation Law so requires, such
indemnified person shall  first deliver  an undertaking  to Bank  of America  to
repay  such  expenses if  its is  ultimately determined  that he  or she  is not
entitled to be indemnified.
 
    The rights of indemnification and  advancement of expenses provided by  Bank
of  America's Bylaws  is not  exclusive of  any other  rights to  which a person
seeking indemnification or  advancement of  expenses may be  entitled under  any
statute,   agreement,  vote  of  stockholders  or  disinterested  directors,  or
otherwise.
 
    Section 145  of  the  Delaware General  Corporation  Law  contains  detailed
provisions  on  indemnification  of  directors  and  officers  against expenses,
judgments, fines  and  amounts  paid  in  settlement,  actually  and  reasonably
incurred in connection with legal proceedings.
 
    Article  IV of Bank of America's Bylaws and the Delaware General Corporation
Law also permit Bank of America to purchase insurance on behalf of its directors
and officers against  liabilities arising out  of their positions  with Bank  of
America,  whether  or  not  such  liabilities  would  be  within  the  foregoing
indemnification  provisions.  Pursuant  to  this  authority,  Bank  of   America
maintains such insurance on behalf of its directors and officers.
 
    2. BANK OF AMERICA, FSB
 
    As  a  federal savings  association, the  terms and  conditions for  Bank of
America, FSB to indemnify its directors, officers, and employees are  prescribed
by  Section 545.121  of Title  12 of the  Code of  Federal Regulations ("Section
545.121"), as follows:
 
                                      II-1
<PAGE>
    (a) For purposes of Section 545.121, the following definitions and rules  of
construction apply:
 
        (1) Definitions.
 
           (i)  Action. The term  "action" means any  judicial or administrative
       proceeding,  or  threatened  proceeding,  whether  civil,  criminal,   or
       otherwise,, including any appeal or other proceeding for review;
 
           (ii)  Court. The term "court" includes, without limitation, any court
       to which or in which any appeal or any proceeding for review is brought.
 
          (iii) Final  judgment. The  term "final  judgment" means  a  judgment,
       decree  or order which  is not appealable  or as to  which the period for
       appeal has expired with no appeal taken.
 
           (iv) Settlement. The term "settlement," includes entry of a  judgment
       by consent or confession or a plea of guilty or nolo contenders.
 
        (2)  Use of References. References in  Section 545.121 to any individual
           or other  person,  including  any association,  shall  include  legal
           representatives, successors, and assigns thereof.
 
    (b) General. Subject to paragraphs (c) and (g) below, a federal savings bank
such  as Bank of America, FSB shall  indemnify any person against whom an action
is brought or threatened because that person  is or was a director, officer,  or
employee of the association, for:
 
        (1)  Any amount for which that person  became liable under a judgment in
           such action; and
 
        (2) Reasonable costs and expenses, including reasonable attorney's fees,
           actually paid or  incurred by  that person in  defending or  settling
           such  action, or in enforcing his or her rights under Section 545.121
           if he or she attains a favorable judgment in such enforcement action.
 
    (c) Requirements. Indemnification shall be made such person under  paragraph
(b) above only if:
 
        (1) Final judgment on the merits is in his or her favor; or
 
        (2) In case of:
 
           (i) Settlement;
 
           (ii) Final Judgment against him or her, or
 
          (iii) Final judgment in his or her favor, other than on the merits, if
       a  majority of the disinterested directors of a federal savings bank such
       as Bank of America, FSB determine that he or she was acting in good faith
       within the scope his or  her employment or authority  as he or she  could
       reasonably have perceived it under the circumstances and for a purpose he
       or  she could reasonably have believed under the circumstances was in the
       best interests of the federal savings bank or its members.
 
           However, no indemnification  shall be made  unless a federal  savings
       bank  such as Bank of America, FSB gives the Office of Thrift Supervision
       (the "OTS")  at least  60 days'  notice  of its  intention to  make  such
       indemnification.  Such notice shall  state the facts  on which the action
       arose, the terms of any settlement, and any disposition of the action  by
       a  court.  Such notice,  a  copy thereof,  and  a certified  copy  of the
       resolution  containing  the  required  determination  by  the  board   of
       directors  shall be sent to the OTS District Director, who shall promptly
       acknowledge receipt thereof. The notice period shall run from the date of
       such receipt. No such indemnification shall  be made if the OTS  Director
       advises  the federal savings bank in  writing, within such notice period,
       of its objection thereto.
 
    (d) Insurance.  A federal  savings bank  such as  Bank of  America, FSB  may
obtain  insurance to protect  it and its directors,  officers and employees from
potential   losses   arising   from   claims    against   any   of   them    for
 
                                      II-2
<PAGE>
alleged  wrongful  acts,  or  wrongful  acts,  committed  in  their  capacity as
directors, officers, or employees. However,  no federal savings bank may  obtain
insurance  which provides  for payment  of losses  of any  person incurred  as a
consequence of his or her willful or criminal misconduct.
 
    (e) Payment of  Expenses. If a  majority of directors  of a federal  savings
bank  such as Bank of America, FSB concludes that, in connection with an action,
any person ultimately may become entitled to indemnification under this section,
the directors may authorize payment of reasonable costs and expenses,  including
reasonable  attorneys'  fees, arising  from the  defense  or settlement  of such
action. Nothing in this paragraph (e)  shall prevent the directors of a  federal
savings  bank such as  Bank of America,  FSB from imposing  such conditions on a
payment of expenses as they deem warranted and in the interests of such  federal
savings  bank. Before making an advance payment of expenses under this paragraph
(e), a  federal savings  bank  such as  Bank of  America,  FSB shall  obtain  an
agreement  that such federal savings bank will be repaid if the person, on whose
behalf payment  is  made,  is  later  determined not  to  be  entitled  to  such
indemnification.
 
    (f)  Exclusiveness of  provisions. A  federal savings  bank such  as Bank of
America, FSB shall not indemnify any  person referred to in paragraph (b)  above
or  obtain insurance referred to in paragraph (d) above other than in accordance
with Section 545.121.
 
    (g) Applicability of section 11(n) of the Federal Deposit Insurance Act. The
indemnification provided for in paragraph (b)  of Section 545.121 is subject  to
and qualified by 12 U.S.C. Section 1821(k). Under Section 1821(k), a director or
officer of an insured depository institution such as Bank of America, FSB may be
held  personally liable  for monetary  damages in  certain civil  actions by, on
behalf of,  or at  the request  or direction  of the  Federal Deposit  Insurance
Corporation  (the "FDIC"). Section  1821(k) provides that  nothing therein shall
impair or affect any right of the FDIC under other applicable law.

ITEM 17.  UNDERTAKINGS
 
    Each of the undersigned registrants hereby undertakes:
 
    (a) To file, during any  period in which offers or  sales are being made,  a
post-effective  amendment  to this  registration statement;  (i) to  include any
prospectus required  by Section  10(a)(3)  of the  Securities  Act of  1933,  as
amended  (the "Securities Act"); (ii) to reflect  in the prospectus any facts or
events arising after the  effective date of the  registration statement (or  the
most  recent  post-effective amendment  thereof) which,  individually or  in the
aggregate, represent a fundamental  change in the information  set forth in  the
registration  statement; (iii) to include  any material information with respect
to the  plan  of  distribution  not previously  disclosed  in  the  registration
statement  or  any  material  change in  such  information  in  the registration
statement; PROVIDED, that (a)(i) and (a)(ii) under this Item 17 shall not  apply
if the information required to be included in a post-effective amendment thereby
is  contained in periodic reports filed pursuant  to Section 13 or Section 15(d)
of the Exchange  Act, that are  incorporated by reference  in this  registration
statement.
 
    (b)  That, for the purpose of determining any liability under the Securities
Act, each such post-effective amendment shall be deemed to be a new registration
statement relating to the securities offered  therein, and the offering of  such
securities  at that time  shall be deemed  to be the  initial bona fide offering
hereof.
 
    (c) To remove from registration by  means of a post-effective amendment  any
of the securities being registered which remain unsold at the termination of the
offering.
 
    (d)  That, for  purposes of determining  any liability  under the Securities
Act, each  filing of  the  registrants' respective  annual reports  pursuant  to
Section  13(a) or 15(d) of the Exchange  Act (and, where applicable, each filing
of an employee  benefit plan's annual  report pursuant to  Section 15(d) of  the
Exchange  Act) that is incorporated by  reference in this registration statement
shall be deemed to  be a new registration  statement relating to the  securities
offered herein, and the offering of such securities at that time shall be deemed
to be the initial bona fide offering thereof.
 
    (e)  To  provide  to  the  underwriters  at  the  closing  specified  in the
underwriting agreements  certificates in  such denominations  and registered  in
such  names as required  by the underwriters  to permit prompt  delivery to each
purchaser.
 
                                      II-4
<PAGE>
    (f) That  insofar  as  indemnification for  liabilities  arising  under  the
Securities  Act may be permitted to  directors, officers and controlling persons
of the registrant pursuant to the  provisions described under Item 15 above,  or
otherwise,  the  registrants  have  been  advised that  in  the  opinion  of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in  the Securities  Act and  is, therefore,  unenforceable. In  the
event  that a claim for indemnification against such liabilities (other than the
payment by the registrants of expenses  incurred or paid by a director,  officer
or  controlling person  of either  registrant in  the successful  defense of any
action, suit or proceeding) is asserted by such director, officer or controlling
person in connection with the securities being registered, the registrants will,
unless in  the  opinion  of  their  counsel  the  matter  has  been  settled  by
controlling  precedent,  submit  to  a  court  of  appropriate  jurisdiction the
question whether  such  indemnification  by  it  is  against  public  policy  as
expressed  in the Securities Act and will  be governed by the final adjudication
of such issue.
 
    (g) That, for  purposes of  determining any liability  under the  Securities
Act,  the information omitted from the form  of prospectus filed as part of this
Registration Statement in  reliance upon Rule  430A and contained  in a form  of
prospectus  filed by the registrants pursuant to Rule 424(b)(1) or (4) or 497(h)
under the  Securities Act  shall be  deemed  to be  apart of  this  Registration
Statement as of the time it was declared effective.
 
    (h)  That, for the purpose of determining any liability under the Securities
Act, each post-effective amendment that contains  a form of prospectus shall  be
deemed  to be  a new registration  statement relating to  the securities offered
therein, and the offering of such securities at that time shall be deemed to  be
the initial bona fide offering thereof.

    Re:  BankAmerica Manufactured Housing Contract Trust
       Pass-Through Certificates (issuable in series)
       Registration Statement on Form S-3
    
 
Ladies and Gentlemen:
 
   
    We  have acted  as special  counsel to  Bank of  America National  Trust and
Savings Association ("Bank  of America")  and BankAmerica  Housing Services,  an
unincorporated division of Bank of America, FSB ("BankAmerica Housing Services,"
and  collectively with Bank  of America, the  "Registrants"), in connection with
the registration  statement  (the "Registration  Statement")  on Form  S-3  (No.
333-3200) filed with the Securities and Exchange Commission under the Securities
Act   of  1933,  as  amended.  The  Registration  Statement  covers  BankAmerica
Manufactured   Housing   Contract   Trust,   Pass-Through   Certificates    (the
"Certificates")  to be issued by  one or both of the  Registrants in one or more
series (each, a "Series") of Certificates.  Each Series of Certificates will  be
issued  pursuant to a Pooling and  Servicing Agreement (a "Pooling and Servicing
Agreement") among one or both Registrants,  in each case as Seller,  BankAmerica
Housing  Services, as Servicer (the "Servicer"),  and a Trustee to be identified
in the prospectus supplement for such Series of Certificates (the "Trustee").  A
Form  of the Pooling  and Servicing Agreement  is included as  an exhibit to the
Registration  Statement   and  is   incorporated  therein   by  reference.   The
Certificates  are to be sold from time to  time as set forth in the Registration
Statement,  any  amendment  thereto,  the  prospectus  contained  therein   (the
"Prospectus")  and supplements to the Prospectus (the "Prospectus Supplements").
Capitalized terms  used and  not otherwise  defined herein  have the  respective
meanings ascribed to such terms in the Registration Statement.
    
 
   
    In  connection with this  Opinion, we have  examined such corporate records,
documents, instruments, certificates of public officials and of the  Registrants
and  such  questions of  law  as we  have deemed  necessary  for the  purpose of
rendering the opinions set forth herein.
    
 
    In such examination, we have assumed  (i) the genuineness of all  signatures
and  the  authenticity  of  all  items submitted  to  us  as  originals  and the
conformity with originals of all items submitted to us as copies, and (ii)  that
the Pooling and Servicing Agreement will be executed and delivered substantially
in  the form  filed as  an exhibit  to the  Registration Statement  and that the
Certificates will be sold as described therein.
 
    The  opinions   hereinafter  expressed   are   subject  to   the   following
qualifications and exceptions:
 
    1.    the  effect of  bankruptcy,  insolvency,  reorganization, arrangement,
moratorium or  other  similar  laws  relating to  or  affecting  the  rights  of
creditors  generally, including without limitation,  laws relating to fraudulent
transfers or conveyances, preferences and equitable subordination; and
 
    2.    limitations  imposed  by   general  principles  of  equity  upon   the
availability  of  equitable remedies  or the  enforcement  of provisions  of the
Pooling and Servicing Agreement; and the effect of judicial decisions which have
held that certain  provisions are  unenforceable where  their enforcement  would
violate  the  implied  covenant of  good  faith  and fair  dealing  or  would be
commercially unreasonable, or where their breach is not material.

    We express no  opinion as to  matters governed by  laws of any  jurisdiction
other  than the  laws of  the State of  California and  the federal  laws of the
United States of America.
 
    Based upon and subject to the foregoing, we are of the opinion that:
 
   
    1.  When a Pooling and Servicing Agreement for a Series of Certificates  has
been authorized by all necessary corporate action and has been duly executed and
delivered  by each  Registrant party thereto,  the Servicer and  the Trustee, it
will constitute valid and binding  obligations of each Registrant party  thereto
and the Servicer, enforceable against each of them in accordance with its terms.
    
 
   
    2.   When a Pooling and Servicing Agreement for a Series of Certificates has
been authorized by all necessary corporate action and has been duly executed and
delivered, and the Certificates of such Series have been duly authorized by  all
necessary  corporate action by  each Registrant, the  Servicer, and the Trustee,
and when the Certificates of such Series have been duly executed,  authenticated
or countersigned, delivered and sold as described in the Registration Statement,
the  Prospectus and Prospectus Supplement  relating thereto, the Certificates of
such Series  will be  legally  issued, fully  paid  and nonassessable,  and  the
holders  of the  Certificates of  such Series will  be entitled  to the benefits
provided  by  the  Pooling  and  Servicing  Agreement  pursuant  to  which   the
Certificates of such Series were issued.
    
 
    We  consent to  the use of  this opinion  as an exhibit  to the Registration
Statement and further consent  to the reference to  us under the caption  "Legal
Matters"  in the Prospectus which  is part of the  Registration Statement and in
Prospectus Supplements related thereto.

    Re:  BankAmerica Manufactured Housing Contract Trust
         Pass-Through Certificates (issuable in series)
         Registration Statement on Form S-3
 
Ladies and Gentlemen:
 
   
    We  have acted as your  special tax counsel in  connection with the proposed
issuance by Bank  of America National  Trust and Savings  Association ("Bank  of
America") or BankAmerica Housing Services, an unincorporated division of Bank of
America,  FSB  ("BankAmerica Housing  Services," and  collectively with  Bank of
America, the "Registrants"), or  both of them,  in one or  more series (each,  a
'Series')  of  BankAmerica  Manufactured  Housing  Contract  Trust, Pass-Through
Certificates (the "Certificates").  Each Series of  Certificates will be  issued
pursuant  to  a  Pooling  and  Servicing  Agreement  (a  "Pooling  and Servicing
Agreement") among one or  both Registrants, in each  case as a Contract  Seller,
BankAmerica Housing Services, as Servicer, and a Trustee to be identified in the
Prospectus  Supplement  for such  Series of  Certificates (the  "Trustee"). Each
Series of Certificates will be offered  pursuant to a Registration Statement  on
Form  S-3 (Registration No.  333-3200) originally filed  with the Securities and
Exchange Commission  (the "Commission")  on April  4, 1996,  as amended  (as  so
amended, the "Registration Statement"). Capitalized terms used and not otherwise
defined  herein  have the  respective  meanings ascribed  to  such terms  in the
Registration Statement.
    
 
   
    We have advised the  Registrants in connection with  the description of  the
material  federal income  tax consequences to  holders of  the Certificates that
appears under the headings "Summary of Terms -- Federal Income Tax Consequences"
and "Certain Federal Income Tax Consequences" in the Prospectus included in  the
Registration  Statement (the "Legal  Descriptions"), and we  confirm our opinion
that the Legal  Descriptions are accurate  in all material  respects. While  the
Legal  Descriptions discuss material anticipated federal income tax consequences
of the purchase,  ownership and  disposition of  the Certificates,  they do  not
purport  to discuss all federal tax consequences of the proposed issuance of the
Certificates and our opinion is limited to those federal income tax consequences
specifically discussed therein.
    
 
    This opinion  is furnished  to you  solely for  use in  connection with  the
Registration  Statement. We hereby  consent to the  filing of this  letter as an
exhibit to the Registration Statement and to the reference to our firm under the
heading "Certain Federal Income  Tax Consequences" in  the Prospectus forming  a
part  of the Registration Statement. In giving such consent, we do not admit and
we hereby disclaim that we come within the category of persons whose consent  is
required under Section 7 of the Securities Act of 1933, as amended, or the rules
and  regulations  of the  Commission thereunder,  nor  do we  admit that  we are
experts with  respect to  any part  of such  Registration Statement  within  the
meaning of the term "experts" as used in the Securities Act of 1933, as amended,
or the rules and regulations of the Commission thereunder.

    Re:  BankAmerica Manufactured Housing Contract Trust
       [Senior/Subordinate] Pass-Through Certificates, Series 19[  ]-[  ]
    
 
Ladies and Gentlemen:
 
   
    We  are special tax  counsel to Bank  of America National  Trust and Savings
Association  ("Bank   of  America")   and  BankAmerica   Housing  Services,   an
unincorporated division of Bank of America, FSB ("BankAmerica Housing Services,"
and collectively with Bank of America, the "Registrants") in connection with the
issuance and sale by the Registrants of approximately $      aggregate principal
amount  of BankAmerica Manufactured Housing Contract Trust, [Senior/Subordinate]
Pass-Through Certificates,  Series  19    -     ,  Class  [A]  (the  "Class  [A]
Certificates") and $      aggregate principal amount of BankAmerica Manufactured
Housing  Contract Trust, [Senior/Subordinate]  Pass-Through Certificates, Series
199 -   , Class [B]  (the "Class [B] Certificates;" collectively with the  Class
[A]  Certificates,  the  "Certificates").  The  Certificates  are  to  be issued
pursuant to a Pooling and Servicing Agreement, dated as of            , 19  (the
"Agreement") among the Registrants,  BankAmerica Housing Services, as  Servicer,
and       , as Trustee. The Certificates will represent undivided interests in a
trust  fund (the  "Trust Fund") consisting  primarily of a  pool of manufactured
housing  installment  sales  contracts  and  installment  loan  agreements  (the
"Contracts")  which [one  or more  of the]  the Registrants  will convey  to the
Trustee, as trustee for the Trust Fund, pursuant to the Agreement.
    
 
    In connection with this opinion, we have examined the following documents:
 
1.  the Agreement;
 
2.   the  registration  statement  on  Form S-3  (No.  333-3200)  filed  by  the
    Registrants  relating to the Certificates, Amendment  No. 1 thereto as filed
    with the Securities and Exchange Commission (the "Commission") in accordance
    with the provisions of the Securities Act of 1933, as amended, and the rules
    and regulations of the Commission thereunder (collectively, the "Act"),  and
    evidence satisfactory to us that such registration statement, as so amended,

each other entity has  the power and  authority to execute  and deliver, and  to
perform  and observe the provisions of such documents, and the due authorization
by each such entity of all requisite  action and the due execution and  delivery
of  such documents by each  such entity. To the  extent we have deemed necessary
and proper, we have relied upon  the representations and warranties as to  facts
of the Registrants contained in the Agreement.
 
    The  opinions  expressed  herein  are  based  upon  current  statues, rules,
regulations, cases and official interpretive  opinions, and cover certain  items
that are not directly or definitively addressed by such authorities.
 
    Based upon and subject to the foregoing, we are of the opinion that:
 
   
    1.   The statements  contained in the Prospectus  under the heading "Certain
Federal Income Tax Consequences," to the  extent they constitute matters of  law
or  legal  conclusions  with  respect  thereto,  are  accurate  in  all material
respects, under the assumptions stated therein and under existing law.
    
 
    2.  Assuming (i) the  making of a valid  election, (ii) compliance with  the
Agreement,  and  (iii) compliance  with any  changes in  the law,  including any
amendments to the  Internal Revenue  Code of 1986,  as amended  (the "Code")  or
applicable  Treasury Regulations thereunder,  the Trust Fund  will be classified
for federal income tax purposes as  a "real estate mortgage investment  conduit"
("REMIC") within the meaning of Code Section 860D.
 
    We  express no opinion  as to matters  governed by laws  of any jurisdiction
other than the  substantive laws of  the State  of California, the  laws of  the
State of New York and the federal laws of the United States of America.
 
    This  opinion is  furnished to  you solely  for use  in connection  with the
issuance and sale of the Certificates. We  hereby consent to the filing of  this
letter  as an exhibit to a Current Report on Form 8-K filed by you in connection
with the Trust  Fund. In  giving such  consent, we do  not admit  and we  hereby
disclaim  that we come within the category  of persons whose consent is required
under Section 7  of the Securities  Act of 1933,  as amended, or  the rules  and
regulations  of the Commission thereunder,  nor do we admit  that we are experts
with respect to any part of the Registration Statement within the meaning of the
term "experts" as used in the Securities  Act of 1933, as amended, or the  rules
and regulations of the Commission thereunder.
 
                                          Very truly yours,
