The date of this Prospectus Supplement is July 31, 1997
<PAGE>
    The  BankAmerica  Manufactured  Housing  Contract  Trust  Senior/Subordinate
Pass-Through Certificates,  Series 1997-1  (the "Certificates")  will  represent
interests  in a  pool (the  "Contract Pool")  of actuarial  manufactured housing
installment sales contracts  and installment loan  agreements (the  "Contracts")
and  certain related  property (the  Contracts and  such related  property being
referred to as the "Trust  Fund"). The Contracts will  be conveyed to the  Trust
Fund  by BankAmerica  Housing Services,  an unincorporated  division of  Bank of
America, FSB ("BankAmerica Housing Services").  Each Contract was originated  by
BankAmerica  Housing Services on  an individual basis in  the ordinary course of
its business.  BankAmerica  Housing  Services  will serve  as  servicer  of  the
Contracts  (together  with any  successor  servicer, the  "Servicer").  The term
"approximate,"  with  respect   to  the  aggregate   principal  amount  of   any
Certificates  or Contracts, means  that the amount  is subject to  a variance of
plus or  minus  5%.  Terms  used  and not  otherwise  defined  herein  have  the
respective  meanings ascribed to such terms in the Prospectus dated June 4, 1996
attached hereto (the "Prospectus").
 
    The Certificates  will  consist  of  nine  classes  of  senior  certificates
(collectively,   the  "Senior   Certificates")  designated  as   the  Class  A-1
Certificates, the Class A-2 Certificates, the Class A-3 Certificates, the  Class
A-4  Certificates, the Class  A-5 Certificates, the  Class A-6 Certificates, the
Class  A-7  Certificates,  the  Class   A-8  Certificates  and  the  Class   A-9
Certificates  and  four classes  of subordinate  certificates designated  as the
Class M Certificates, the Class B-1 Certificates, the Class B-2 Certificates and
the Class R  Certificates (collectively, the  "Subordinate Certificates").  Only
the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-6, Class A-7,
Class  A-8, Class  A-9, Class  M and  Class B-1  Certificates (collectively, the
"Offered Certificates")  are being  offered hereby.  The Class  A-1, Class  A-2,
Class  A-3, Class A-4,  Class A-5, Class  A-6, Class A-7,  Class A-8, Class A-9,
Class M and Class  B-1 Certificates will evidence  in the aggregate  approximate
initial 9.73%, 6.87%, 7.82%, 11.26%, 5.46%, 5.92%, 15.00%, 9.92%, 10.51%, 8.50%,
and 6.00% undivided interests, respectively, in the Contract Pool. The Class B-2
Certificates  will  evidence  in  the  aggregate  an  approximate  initial 3.00%
undivided  interest  in  the  Contract  Pool.  The  Class  B-1  and  Class   B-2
Certificates  are referred to collectively as the "Class B Certificates" herein.
The rights of  the Subordinate  Certificateholders to  receive distributions  of
principal  and interest are  subordinated as described herein  to such rights of
the  Senior  Certificateholders  and  the  rights   of  Class  B  and  Class   R
Certificateholders to receive distributions are subordinated as described herein
to   such   rights   of  the   Senior   Certificateholders  and   the   Class  M
Certificateholders. See "Description of the Certificates" herein.
 
    Distributions of principal and interest on the Certificates will be made  to
the  holders of the Certificates on  the 10th day of each  month (or if the 10th
day is not a business day, the next business day) (each, a "Distribution Date"),
beginning in August, 1997. The Class A-1, Class A-2, Class A-3, Class A-4, Class
A-5, Class A-6, Class A-7,  Class A-8, Class M  and Class B-1 Certificates  will
have  the respective fixed Pass-Through  Rates specified above. The Pass-Through
Rate for the Class A-9  Certificates is subject to a  maximum rate equal to  the
weighted   average  of  the  Net  Contract  Rates  in  the  Contract  Pool.  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
Certificates, other  than  the Class  R  Certificates, will  represent  "regular
interests"  in the REMIC.  See "Certain Federal  Income Tax Consequences" herein
and in the Prospectus.
                              -------------------
 
    The  underwriters  named  herein  (the  "Underwriters")  intend  to  make  a
secondary  market in the Offered Certificates, but  have no obligation to do so.
There can be no assurance that  a secondary market for the Offered  Certificates
will develop, or if it does develop, that it will continue or provide sufficient
liquidity. See "Risk Factors" herein and in the Prospectus.

offering of the Offered Certificates. Additional information is contained in the
Prospectus and purchasers are urged to read both this Prospectus Supplement  and

meanings ascribed to such terms in the Prospectus.
 
    This  Prospectus Supplement may be used  by BancAmerica Securities, Inc., an
affiliate of  the Seller  and  Servicer, in  connection  with offers  and  sales
related  to market making transactions  in the Offered Certificates. BancAmerica

                              In general, a "Liquidated Contract" is a defaulted
                              Contract as to which all amounts that the Servicer
                              expects  to  recover  relating  to  such  Contract
                              ("Liquidation  Proceeds")  have  been  received. A
                              Liquidated   Contract   includes   any   defaulted
                              Contract   in   respect  of   which   the  related
                              Manufactured  Home  has  been  realized  upon  and
                              disposed  of and the  proceeds of such disposition
                              have been received.
 
                              The "Certificate Balance" for any Class as of  any
                              Distribution   Date  is  the  Initial  Certificate
                              Balance of that Class less all amounts  previously
                              distributed to Certificateholders of that Class on
                              account  of  principal.  The  "Senior  Certificate
                              Balance" as of any Distribution Date is the sum of
                              the   Certificate   Balances    of   the    Senior
                              Certificates immediately prior to such
                              Distribution  Date.  The  "Subordinate Certificate
                              Balance" as of any Distribution Date is the sum of
                              the  Class  M   Certificate  Balance,  Class   B-1
                              Certificate  Balance and the Class B-2 Certificate
                              Balance immediately  prior  to  such  Distribution
                              Date.    In   no   event   shall   the   aggregate
                              distributions of principal to  the holders of  any

                              Certificateholders  by  the  subordination  of the
                              Class B-2  Certificates  (in  each  case,  to  the
                              extent  described herein) will  be accomplished by
                              the  application  of  the  Available  Distribution
                              Amount  (together  with any  Reserve  Account Draw

                              intended to protect such Certificateholders by the

                              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

                              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

                              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 1997-1 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   Balance   of   the

                              aggregate Certificate Balance of the  Certificates
                              on any Distribution Date, shortfalls and/or losses
                              will arise with respect to the Certificates, which
                              shortfalls  and/or  losses  will be  borne  by the
                              Class  B-2  Certificateholders,   the  Class   B-1

                              and the Senior Certificateholders, in that order.
 
Monthly Advances............  For  each Distribution Date,  the Servicer will be
                              obligated to make an advance (a "Monthly Advance")
                              equal to the  lesser of  (i) delinquent  scheduled
                              payments   of  principal   and  interest   on  the
                              Contracts  that   were   due  in   the   preceding

                              which scheduled  distributions  of  principal  and
                              interest   due  on   the  Series   1997-1  Regular

                              Servicer's  judgment,  such advance  would  not be
                              recoverable   from    related    late    payments,
                              Liquidation  Proceeds  or otherwise.  Advances are

                              Services  as the lienholder, and the UCC financing

                              BankAmerica  Housing  Services  as  secured party.
                              Because  of   the   expense   and   administrative
                              inconvenience  involved, neither  the certificates
                              of title for  the Manufactured Homes  nor the  UCC
                              financing   statements  evidencing   the  security
                              interest  in  such  Manufactured  Homes  will   be
                              notated  or amended, as the case may be, to change
                              the lienholder specified  therein to the  Trustee.
                              Similarly,  BankAmerica Housing  Services will not
                              record  an  assignment  to  the  Trustee  of   the

                              and Land-in-Lieu Contract. In some states, in  the

                              Contract may not be effective against creditors of
                              BankAmerica Housing Services. However, the  Seller
                              will  not be obligated to repurchase or substitute
                              a Contract solely on the  basis of the failure  by
                              BankAmerica  Housing  Services to  cause  any such
                              notation or amendment to be made with respect to a
                              document  of  title  or  UCC  financing  statement
                              relating  to  a  Manufactured  Home,  except under
                              certain limited specified circumstances  described
                              herein  under "Description  of the  Certificates -

                              Under the  Agreement,  the Seller  will  agree  to
                              repurchase,  or at  its option  substitute another
                              contract for,  a Contract  sold by  it if  it  has
                              failed   to  perfect   a  first-priority  security
                              interest in such Manufactured Home or in the event
                              of  certain  violations   of  federal  and   state
                              consumer  protection laws  applicable to creditors
                              or assignees of the Contracts, unless such failure
                              does  not  materially  and  adversely  affect  the

                              the  value  of manufactured  homes,  the Trustee's
                              security interest in a Manufactured Home could  be
                              rendered  subordinate  to  the  interest  of other
                              parties if the  Manufactured Home  (that does  not
                              secure  a Land Home  or Land-in-Lieu Contract) has

                              the Seller will stamp or cause to be stamped  each
                              Contract   with  a  legend   indicating  that  the
                              Contract has been assigned to the Trustee.
Optional Termination and
 Termination Auction........  The Servicer has the  option to purchase from  the
                              Trust  Fund all Contracts then outstanding and all
                              other  property   in  the   Trust  Fund   on   any
                              Distribution  Date after the Distribution Date if,
                              among  other   conditions,  the   Pool   Scheduled
                              Principal  Balance is less than 10% of the Cut-off
                              Date Pool Principal  Balance. See "Description  of
                              the    Certificates--Optional    Termination   and
                              Termination Auction" herein.  During that  period,
                              the  Servicer  also  may  direct  the  Trustee  to
                              conduct a Termination Auction for the sale of  all
                              Contracts then outstanding in the Trust Fund, and,
                              in  any event,  if the Servicer  has not exercised
                              the option  call  within  90  days  of  the  first
                              Distribution   Date   when   the   Pool  Scheduled
                              Principal Balance is less than 10% of the  Cut-off
                              Date  Pool Principal  Balance, the  Servicer shall
                              direct  the  Trustee  to  conduct  a   Termination
                              Auction. See "Description of the
                              Certificates--Optional Termination and Termination
                              Auction"  herein.  Any  early  termination  of the
                              Trust   Fund   and   early   retirement   of   the
                              Certificates  that  results  from  the  Servicer's
                              exercise  of  the  option  call  or  a  successful
                              Termination  Auction  may  have  an  effect  on an
                              investor's  yield   on  such   Certificates.   See
                              "Prepayment  and Yield  Considerations" herein and

Registration of Offered
 Certificates...............  The  Offered   Certificates  initially   will   be
                              represented by certificates registered in the name
                              of  Cede  & Co.  ("Cede")  as the  nominee  of The
                              Depository Trust Company ("DTC"), and will only be
                              available in  the  form  of  book-entries  on  the
                              records  of DTC and participating members thereof.
                              Certificates representing the Offered Certificates
                              will be issued in  definitive form only under  the
                              limited   circumstances   described   herein.  All
                              references herein to "holders" or
                              "Certificateholders" shall reflect  the rights  of
                              beneficial  owners  of  the  Offered  Certificates
                              ("Certificate  Owners")  as  they  may  indirectly
                              exercise such rights through DTC and participating
                              members  thereof,  except  as  otherwise specified
                              herein. See "Risk Factors" and "Description of the
                              Certificates--Global Certificates" in the

Federal Income Tax
 Consequences...............  For  federal income tax purposes, an election will
                              be made to treat certain assets of the Trust  Fund
                              as  a  real  estate  mortgage  investment  conduit
                              ("REMIC"). The Series 1997-1 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   1997-1    Residual
                              Certificates  will  be  treated  as  the "residual
                              interest" in  the  REMIC for  federal  income  tax
                              purposes. Holders of the Series

                              1997-1  Regular Certificates  that would otherwise
                              report income under  a cash  method of  accounting
                              will  be required to include in income interest on
                              the Series 1997-1 Regular Certificates  (including
                              original   issue  discount  ("OID"),  if  any)  in
                              accordance with the 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

ERISA Considerations........  SENIOR CERTIFICATES. Subject to the conditions and
                              discussion    set   forth   herein,   the   Senior
                              Certificates may be purchased by employee  benefit
                              plans  that are subject to the Employee Retirement
                              Income Security Act of 1974, as amended ("ERISA").
                              See  "ERISA  Considerations"  herein  and  in  the
                              Prospectus.
                              SUBORDINATE   CERTIFICATES.  Unless   the  opinion
                              referred to under "ERISA Considerations - Class  M
                              and  Class B-1  Certificates" is  delivered to the
                              Trustee, an employee  benefit plan  or other  plan
                              subject  to  ERISA  and/or  Section  4975  of  the
                              Internal Revenue  Code of  1986, as  amended  (the
                              "Code")  will not be permitted to purchase or hold
                              the Class M  or the Class  B Certificates as  such
                              actions  may give rise to a transaction prohibited
                              under ERISA  or  Section  4975 of  the  Code.  See
                              "ERISA   Considerations"   herein   and   in   the
                              Prospectus.
Legal Investment............  The  Senior   Certificates   and   the   Class   M
                              Certificates  at the time of issuance will qualify
                              as  "mortgage   related  securities"   under   the
                              Secondary Mortgage Market Enhancement Act of 1984,
                              as amended ("SMMEA") and, as such, will constitute
                              legal  investments for certain  types of investors
                              to the extent provided in SMMEA. Such institutions
                              should  consult  their   own  legal  advisors   in
                              determining  whether and to what extent the Senior
                              Certificates  and   the   Class   M   Certificates
                              constitute legal investments for such investors.
                              Because  the Class  B-1 Certificates  will not, at
                              the time of issuance, be  rated in one of the  two
                              highest  rating categories  of Moody's  and Fitch,
                              the Class  B-1  Certificates will  not  constitute
                              "mortgage  related  securities"  for  purposes  of
                              SMMEA. Accordingly, many  institutions with  legal
                              authority   to   invest  in   more   highly  rated
                              securities   based    on   manufactured    housing
                              obligations  may  not  be  legally  authorized  to
                              invest  in   the   Class  B-1   Certificates.   No
                              representation   is  made  as  to  any  regulatory
                              requirements or considerations (including  without
                              limitation   regulatory  capital   or  permissible
                              investment   requirements)   applicable   to   the
                              purchase  of the Class  B-1 Certificates by banks,
                              savings and loan  associations or other  financial
                              institutions.  Such  institutions  should  consult
                              their own  legal advisors  in determining  whether
                              and   to  what  extent  the  Offered  Certificates
                              constitute legal investments  for such  investors.
                              See   "Legal   Investment"  herein   and   in  the
                              Prospectus.

Rating......................  It is a condition to  the issuance of the  Offered
                              Certificates that the Senior Certificates be rated
                              at least "Aaa" by Moody's and "AAA" by Fitch, that
                              the  Class M Certificates be  rated at least "Aa3"
                              by Moody's and "AA-" by  Fitch and that the  Class
                              B-1  Certificates  be  rated  at  least  "Baa2" by
                              Moody's and  "BBB" by  Fitch. The  Seller has  not
                              requested  ratings on the  Offered Certificates by
                              any rating agency  other than  Moody's and  Fitch.
                              However,  there can be no  assurance as to whether
                              any other rating  agency will rate  any or all  of
                              the  Offered  Certificates,  or if  it  does, what
                              rating would be assigned by any such other  rating
                              agency.  A  rating on  any or  all of  the Offered
                              Certificates by certain other rating agencies,  if
                              assigned  at  all, may  be  lower than  the rating
                              assigned  to  such  Certificates  by  Moody's  and
                              Fitch. See "Ratings" herein and in the Prospectus.
                              A  security rating is not a recommendation to buy,
                              sell or  hold securities  and  may be  subject  to
                              revision or withdrawal at any time.

                                  RISK FACTORS
 
    The discussion under "Risk Factors" in the Prospectus should be read
carefully in connection with a decision to invest in any of the Offered
Certificates. The following discussion supplements, and does not replace or
supersede the discussion under "Risk Factors" in the Prospectus, unless the
context expressly so provides.
 
    1.  LIMITED LIQUIDITY.  Only the Offered Certificates are being offered
hereby. The Underwriters intend to make a secondary market in the Offered
Certificates, but have no obligation to do so. There can be no assurance that a
secondary market will develop for the Offered Certificates or, if it does
develop, that it will provide the holders of any Class of Offered Certificates
with liquidity of investment or that it will remain for the term of such Class
of Offered Certificates.
 
    The Class B-1 Certificates will not constitute "mortgage related securities"
for purposes of SMMEA. Accordingly, many institutions with legal authority to
invest in SMMEA securities will not be able to invest in the Class B-1
Certificates, limiting the market of such securities.
 
    2.  DISTRIBUTIONS OF PRINCIPAL.  The yield to maturity on the Class M and
Class B-1 Certificates will be affected by the rate at which Contracts become
Liquidated Contracts and the severity of ensuing losses on such Liquidated
Contracts and the timing thereof. For any Distribution Date before the Class M
Principal Distribution Test has been met on which the Senior Certificate Balance
has not been reduced to zero, the Senior Certificateholders will receive all
payments of principal that are made on the Contracts. For any Distribution Date
after the Class M Principal Distribution Test has been met but before the Class
B Distribution Test has been met on which each of the Senior Certificate Balance
and the Class M Certificate Balance has not been reduced to zero, the Senior
Certificateholders and the Class M 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 Senior
Certificate Balance or the Class M Certificate Balance, as applicable, will be
reduced to zero, which occurrences will be affected by the rate of voluntary
prepayments in addition to prepayments due to default and subsequent
liquidation. Prepayments on Contracts may be influenced by a variety of
economic, geographic, social and other factors, including repossessions, aging,
seasonality, market interest rates, changes in housing needs, job transfers and
unemployment. See "Prepayment and Yield Considerations" herein and in the
Prospectus.
 
    3.  NO RECOURSE.  Neither BankAmerica Housing Services nor any of its
affiliates will have any obligations with respect to the Offered Certificates
except, in the case of the Seller, for obligations arising from certain of its
representations and warranties with respect to the Contracts and for certain
contractual servicing obligations, each as further described herein. SUBJECT
ONLY TO THE FOREGOING EXCEPTIONS, THE OFFERED CERTIFICATES WILL NOT REPRESENT
INTERESTS IN OR OBLIGATIONS OF BANK OF AMERICA NATIONAL TRUST AND SAVINGS
ASSOCIATION OR 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 Certificates will include the benefit of a guarantee
or limited guarantee of the Seller or an affiliate thereof. NONE OF THE OFFERED
CERTIFICATES NOR THE UNDERLYING CONTRACTS OR ANY COLLECTIONS THEREON WILL BE
INSURED OR GUARANTEED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION OR BY ANY
OTHER GOVERNMENTAL AGENCY OR INSTRUMENTALITY.
 
    4.  SUBORDINATION OF CLASS M AND CLASS B CERTIFICATES.  The rights of the
holders of the Class M Certificates to receive distributions of available
amounts in the Trust Fund will be subordinate, to the extent described herein,
to the rights of the holders of the Senior Certificates. Consequently, if
shortfalls and/or losses arise with respect to the Certificates, they will be
borne by the Class M Certificateholders before they are borne by the Senior
Certificateholders. The rights of the holders of the Class B Certificates to
receive distributions of available amounts in the Trust Fund will be
subordinate, to the extent described herein, to the rights of the holders of the
Class M Certificates. Consequently, if shortfalls and/
 
                                      S-22
<PAGE>
or losses arise with respect to the Certificates, they will be borne by the
Class B Certificateholders before they are borne by the Class M
Certificateholders.
 
    5.  PREPAYMENTS MAY AFFECT PASS-THROUGH RATES.  The Pass-Through Rate for
each of the Certificates of Class A-9 and Class B-2 on any Distribution Date
will be adjusted so as not to exceed the weighted average of the Net Contract
Rates in the Contract Pool. Disproportionate prepayments (including prepayments
due to liquidations and repurchases by the Seller as required or permitted by
the Agreement) of Contracts with Net Contract Rates in excess of the initial
Pass-Through Rates (each an "Initial Pass-Through Rate") for the Class A-9 and
Class B-2 Certificates will increase the possibility that the Pass-Through Rate
for such Classes of Certificates will be adjusted to an amount lower than the
related Initial Pass-Through Rate. There is no mechanism to compensate Holders
of such Classes of Certificates for any such reduction. Any difference between
interest at the actual Pass-Through Rate and interest at the Initial
Pass-Through Rate will not constitute a shortfall, and any such difference will
be foregone permanently.
 
                               THE CONTRACT POOL
 
    Each Contract was originated by BankAmerica Housing Services on an
individual basis in the ordinary course of its business. A description of
BankAmerica Housing Services' 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 Seller will
convey to the Trust Fund the Contracts. 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.
 
    The Contracts are all fixed rate actuarial Contracts. Some of the Contracts
in the Contract Pool are secured by a lien on real estate. None of the Contracts
(i) was purchased in bulk from an unrelated third party, (ii) is insured in
whole or in part or guaranteed in whole or in part, as applicable, by the
Veterans Administration, the Federal Housing Administration or by any other
governmental entity or instrumentality, (iii) is amortized using the "simple
interest" amortization method or (iv) has a variable Contract Rate or a Contract
Rate which steps up on particular dates.
 
    Management of BankAmerica Housing Services estimates that in excess of 90%
of the Manufactured Homes are used as primary residences by the Obligors under
the Contracts secured by such Manufactured Homes.
 
    As of the Cut-off Date, the Contract Rates on the Contracts ranged from
8.00% to 13.50%. The weighted average Contract Rate of the Contracts as of the
Cut-off Date was approximately 10.72%. As of the Cut-off Date, the Contracts had
remaining scheduled maturities of not more than 360 months, and original
scheduled maturities of at least 22 months but not more than 362 months. As of
the Cut-off Date, the Contracts had a weighted average remaining term to
maturity of approximately 277 months, and a weighted average original term to
scheduled maturity of approximately 280 months. The average outstanding
principal balance of the Contracts as of the Cut-off Date was approximately
$29,877 and the outstanding principal balances of the Contracts as of the
Cut-off Date ranged from approximately $2,378 to $121,824. The weighted average
loan-to-value ratio for the Contracts at origination was approximately 89.57%
and the loan-to-value ratio of the Contracts at origination ranged from 14% to
100%. "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, and premiums for related
insurance. 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
 
                                      S-23
<PAGE>
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 45 states;
approximately 9.41% of the Contracts by outstanding principal balance as of the
Cut-off Date were secured by Manufactured Homes located in Georgia, 9.23% in
Texas, 8.42% in Alabama, 6.68% in North Carolina, 6.05% in Florida. No other
state represented more than 5% (by outstanding principal balance as of the
Cut-off Date) of the Contracts.
 
    Approximately 79% 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 21% of the Contracts by
outstanding principal balance as of the Cut-off Date are secured by Manufactured
Homes which were used at the time the related Contracts were originated.
Approximately 7.32% of the Contracts by outstanding principal balance as of the
Cut-off Date are secured by liens on real estate as well as on Manufactured
Homes. See "Certain Legal Aspects of the Contracts" herein.

(1) Rounded to the nearest 1%. The definition of "Value" is set forth under "The
    Contract Pool" above. Manufactured Homes, unlike site-built homes, generally
    depreciate in value, and it should generally be expected, especially with
    Contracts with high loan-to-value ratios at origination, that at any time
    after the origination of a Contract, the market value of the Manufactured
    Home securing such Contract may be lower than the outstanding principal
    balance of such Contract.

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 the Trust Fund will be similar  to
that  set forth  above. Management believes  the increase in  the percentage net
losses in 1996 over 1995, and again in the first quarter 1997 (when  annualized)
over  1996, is due primarily  to the seasoning of  the portfolio. 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 has  unfavorably affected
portfolio performance  in  relation  to delinquencies,  repossessions  and  loan
losses  during this period. However, the delinquency, loan loss and repossession
experience of  manufactured housing  contracts historically  has been  adversely
affected  by a downturn in regional or local economic conditions. These regional
or local economic conditions are often volatile, and no predictions can be  made
regarding  future  economic loss  upon  repossession. Information  regarding the
geographic location,  at origination,  of the  Manufactured Homes  securing  the
Contracts in the Contract Pool is set forth under "The Contract Pool" herein.
 
                      PREPAYMENT AND YIELD CONSIDERATIONS
 
    The  general prepayment and yield considerations discussed in the Prospectus
under  "Prepayment  and  Yield  Considerations"  should  be  read  carefully  in
connection  with a decision  to invest in  any of the  Offered Certificates. The
following  discussion  supplements,  and  does  not  replace  or  supersede  the
discussion under "Prepayment and Yield Considerations" in the Prospectus, unless
the context expressly so provides.
 
    The  Contracts had maturities  at origination ranging from  22 months to 362
months, but  may be  prepaid in  full or  in part  at any  time. The  prepayment
experience  of  the  Contracts  (including prepayments  due  to  liquidations of
defaulted Contracts)  will affect  the  average life  and  the maturity  of  the
Offered  Certificates. 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 sixteen  months of  prepayment
information  is  available,  as  described  in  Appendix  A  to  this Prospectus
Supplement. Any pool of  contracts, including the  Contract Pool, might  include
contracts  with contract rates  that are generally higher  or lower, in absolute
terms or  in comparison  to prevailing  rates, than  the contract  rates of  the
contracts  from which are derived certain  historical statistical data set forth
in Appendix A. As a result, the prepayment experience of the contracts contained
in any contract  pool, including the  Contract Pool, might  be faster or  slower
than  the prepayment  experience of  the contracts  reflected in  the historical
data. In addition, although 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; Optional Termination"  and "Certain Legal  Aspects of the
Contracts -- Transfers of Manufactured Homes; Enforceability of Restrictions  on
Transfer"  in the  Prospectus and "Description  of the  Certificates -- Optional
Termination and Termination Auction" herein for a discussion of certain  factors
that  may  influence  prepayments,  including  homeowner  mobility,  general and
regional economic  conditions,  prevailing  interest rates,  provisions  in  the
Contracts  prohibiting the owner from selling  the Manufactured Home without the
prior consent of the  holder of the related  Contract, the early termination  of
the  Trust Fund pursuant to  a successful Termination Auction  and the option of
the Servicer (whether or not BankAmerica Housing Services remains the  Servicer)
to  purchase the Contracts and any other property constituting the Trust Fund or
to direct the
 
                                      S-32
<PAGE>
Trustee to solicit bids  for an auction  for the sale of  the Contracts and  any
other  property  constituting  the  Trust  Fund.  In  addition,  repurchases  of
Contracts on account of  certain breaches of  representations and warranties  as
described  below  under  "Description  of  the  Certificates  --  Conveyance  of
Contracts" will have the effect of  prepaying such Contracts and therefore  will
affect the average life of the Certificates.
 
    The allocation of distributions to the Certificateholders in accordance with
the  Agreement will have the effect  of accelerating the amortization of certain
of the  Classes of  the  Series 1997-1  Regular  Certificates and  delaying  the
amortization  of certain other Classes of the Series 1997-1 Regular Certificates
from the amortization  that otherwise  would be applicable  if distributions  in
respect  of the Total Regular  Principal Amount were made  pro rata according to
the outstanding principal balances of the Series 1997-1 Regular Certificates. If
a purchaser of Offered Certificates in a Class of Offered Certificates purchases
them at a discount and calculates its anticipated yield to maturity based on  an
assumed rate of distributions of principal on such Class of Offered Certificates
that is faster than the rate actually realized, such purchaser's actual yield to
maturity  will be  lower than  the yield  so calculated  by such  purchaser. See
"Description of the  Certificates -- Distributions"  herein and "Prepayment  and
Yield Considerations" in the Prospectus.
 
    There  can be no  assurance that the  delinquency or repossession experience
set  forth  under  "The  Seller   --  Delinquency  and  Loan   Loss/Repossession
Experience"  will be representative of the  results that may be experienced with
respect to  the Contracts.  See  "Prepayment and  Yield Considerations"  in  the
Prospectus for a discussion of the effect delinquencies and repossessions on the
Contracts would have on the average life of the Certificates.
 
    The  expected final scheduled  payment date on the  Contract with the latest
maturity is in July 2027.
 
    The  last  scheduled  Distribution  Dates  for  the  Series  1997-1  Regular
Certificates  are set forth on the cover of this Prospectus Supplement. However,
the actual last Distribution  Date for each such  Class of Offered  Certificates
could  occur significantly earlier than  such scheduled Distribution Dates. When
the Pool Scheduled Principal  Balance falls below 10%  of the Cut-off Date  Pool
Principal  Balance and certain other conditions are met, the Trust Fund could be
terminated pursuant to the Servicer's exercise of an option call or pursuant  to
a  successful  Termination  Auction.  See "Description  of  the  Certificates --
Optional Termination and Termination Auction" herein. Either of these events, if
they occur,  would  result in  the  early  retirement of  the  then  outstanding
Certificates.
 
    As described herein under "Description of the Certificates -- Subordination"
and  "Description of the Certificates -- Losses on Liquidated Contracts," to the
extent that,  on  any  Distribution Date,  the  Available  Distribution  Amount,
together  with the Reserve  Account Draw Amount,  is not sufficient  to permit a
full distribution of the  Total Regular Principal Amount  to the holders of  any
Class  of  Offered  Certificates,  the  effect  will  be  to  cause  the Offered
Certificates to be  amortized more slowly  than they otherwise  would have  been
amortized, and losses on Liquidated Contracts and delinquencies on the Contracts
(if  not covered by Monthly Advances) will be borne by the holders of such Class
of Offered  Certificates in  the manner  described thereunder  and as  described
below.
 
    In  the event there is  a sufficiently large number  of delinquencies on the
Contracts in any Collection Period that were not covered by Monthly Advances  as
described  herein,  the  amounts  distributed  to  the  holders  of  the Offered
Certificates could  be less  than  the amount  of  principal and  interest  that
otherwise  would be  payable on  such Certificates  on the  related Distribution
Date. In  such  event,  even  if  delinquent  payments  on  the  Contracts  were
eventually  recovered upon liquidation,  if the amounts  received do not include
interest on delinquent interest payments,  the effective yield on the  Contracts
would be reduced, and under certain circumstances it is possible that sufficient
Available  Distribution Amounts might not be  available to provide for aggregate
distributions on the  Offered Certificates  equal to  the sum  of their  initial
outstanding Certificate Balances plus accrued interest thereon, thereby reducing
the effective yield on such Certificates.
 
    Obligors are not required to pay interest on the Contracts after the date of
full  prepayment of principal or  the date of a  partial prepayment of principal
(to the extent of such partial prepayment). As a
 
                                      S-33
<PAGE>
result, partial or full prepayments in advance of the related Due Dates for such
Contracts in any Collection Period will  reduce the amount of interest  received
from the related Obligors during such Collection Period to less than one month's
interest. However, when a partial prepayment is made on a Contract or a Contract
is prepaid in full during any Collection Period, but after the Due Date for such
Contract in such Collection Period, the effect will be to increase the amount of
interest received from the related Obligor during such Collection Period to more
than  one month's  interest. If a  sufficient amount of  partial prepayments are
made or  a  sufficient number  of  Contracts are  prepaid  in full  in  a  given
Collection Period in advance of their respective Due Dates, interest received on
all  of  the Contracts  during  that Collection  Period,  after netting  out the
Monthly Servicing Fee (and other expenses of  the Trust Fund), may be less  than
the  interest  payable  on the  Senior  and/or Subordinate  Certificates  on the
related Distribution  Date.  As  a result,  the  Available  Distribution  Amount
(together  with the  Reserve Account Draw  Amount) for  the related Distribution
Date  may  not  be  sufficient  to  distribute  the  interest  on  the   Offered
Certificates  in  the full  amount set  forth herein  under "Description  of the
Certificates -- Distributions"  and to  make a  full distribution  of the  Total
Regular  Principal Amount  to the Senior  and/or Subordinate 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,  except as described above with  respect to prepayments. See "The Contract
Pools" in the  Prospectus. Thus,  the effect of  delinquent Scheduled  Payments,
even if they are ultimately paid by the Obligor, will be to reduce the yields on
such  Contracts below their respective Contract Rates (because interest will not
have accrued  on the  principal portion  of any  Scheduled Payment  while it  is
delinquent).  If the  Servicer does  not make  an advance  with respect  to such
delinquent Contracts  as described  herein, the  result will  be to  reduce  the
effective  yield to the Trust Fund derived  from such Contracts to a yield below
their Contract Rates. Under certain  circumstances, such yield reductions  could
cause the aggregate yield to the Trust Fund derived from the Contract Pool to be
insufficient   to  support   the  distribution   of  interest   on  the  Offered
Certificates, after netting out other expenses of the Trust Fund.
 
    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 March 1, 1997, (f) the WAC of the
contracts in  the pool  as  of March  1,  1997 and  (g)  the percentage  of  the
Prepayment  Model  (as described  in "--  Weighted Average  Life of  the Offered
Certificates" below)  for the  life of  each  pool through  March 1,  1997.  The
prepayment performance of the contract pools described in the following table is
not indicative of the

be given that the prepayment performance of the Contracts in the Trust Fund will
correspond with the prepayment performance of  any of the pools described  below

WEIGHTED AVERAGE LIFE OF THE OFFERED CERTIFICATES
 
    The  following  information  is given  solely  to illustrate  the  effect of
prepayments of  the  Contracts on  the  weighted  average life  of  the  Offered
Certificates  under  the  stated assumptions  and  is  not a  prediction  of the
prepayment rate that might actually be experienced by the Contracts.
 
    Weighted average life refers to the average amount of time from the date  of
issuance of a security until each dollar of principal of such security is repaid
to  the  investor.  The  weighted  average life  of  an  Offered  Certificate is
determined by (i) multiplying the amount of each cash distribution in  reduction
of  the Certificate Balance of such Certificate  by the number of years from the
date of  issuance of  such Certificate  to the  stated Distribution  Date,  (ii)
adding  the  results, and  (iii)  dividing the  sum  by the  Initial Certificate
Balance  of  such  Certificate.  The  weighted  average  life  of  the   Offered
Certificates will be affected by the rate at which principal on the Contracts is
paid.  Principal  payments  on  Contracts  may  be  in  the  form  of  scheduled
amortization or prepayments  (for this purpose,  the term "prepayment"  includes
repayments  (other  than from  scheduled amortization)  and liquidations  due to
default or other  dispositions of  Contracts). Prepayments on  Contracts may  be
measured  by a prepayment standard  or model. The model  used in this Prospectus
Supplement ("Prepayment Model") is based on  an assumed rate of prepayment  each
month  of the then unpaid principal balance of  a pool of new contracts. 100% of
the Prepayment Model  assumes prepayment  rates of 3.7%  per annum  of the  then
unpaid principal balance
 
                                      S-35
<PAGE>
of  such  Contracts in  the first  month of  the  life of  the Contracts  and an
additional 0.1% per annum in each month thereafter (for example, 3.9% per  annum
in  the third month)  until the 24th month.  Beginning in the  24th month and in
each month thereafter during the life  of the Contracts, 100% of the  Prepayment
Model assumes a constant prepayment rate of 6.0% per annum.
 
    As  used in  the following  table, "0% of  the Prepayment  Model" assumes no
prepayments on  the  Contracts;  "100%  of the  Prepayment  Model"  assumes  the
Contracts  will prepay at  rates equal to  100% of the  Prepayment Model assumed
prepayment rates;  "150% of  the Prepayment  Model" assumes  the Contracts  will
prepay  at rates equal to 150% of the Prepayment Model assumed prepayment rates;
"170% of the Prepayment Model" assumes the Contracts will prepay at rates  equal
to  170%  of  the  Prepayment  Model  assumed  prepayment  rates;  "200%  of the
Prepayment Model" assumes the  Contracts will prepay at  rates equal to 200%  of
the  Prepayment Model assumed  prepayment rates; "250%  of the Prepayment Model"
assumes the Contracts will prepay at rates equal to 250% of the Prepayment Model
assumed prepayment  rates;  and  "300%  of the  Prepayment  Model"  assumes  the
Contracts  will prepay at  rates equal to  300% of the  Prepayment Model assumed
prepayment rates.
 
    There is  no assurance,  however,  that prepayments  of the  Contracts  will
conform to any level of the Prepayment Model, and no representation is made that
the  Contracts will prepay at the prepayment rates shown or any other prepayment
rate. The rate of principal payments on pools of manufactured housing  contracts
is  influenced by a  variety of economic, geographic,  social and other factors,
including the  level  of interest  rates  and  the rate  at  which  manufactured
homeowners  sell their manufactured  homes or default  on their contracts. Other
factors affecting  prepayment of  such contracts  include changes  in  obligors'
housing  needs,  job transfers,  unemployment and  obligors'  net equity  in the
manufactured homes. In the case of  mortgage loans secured by site-built  homes,
in  general, if prevailing interest rates  fall significantly below the interest
rates on such mortgage  loans, the mortgage  loans are likely  to be subject  to
higher  prepayment rates than if prevailing  interest rates remained at or above
the rates borne by such mortgage loans. Conversely, if prevailing interest rates
rise above the  interest rates on  such mortgage loans,  the rate of  prepayment
would  be expected to  decrease. In the case  of manufactured housing contracts,
however, because the  outstanding principal  balances are,  in general,  smaller
than  mortgage loan  balances and  the original  term to  maturity of  each such
contract is generally  shorter, the  reduction or increase  in the  size of  the
monthly payments on contracts of the same maturity and principal balance arising
from  a change in the interest  rate thereon is generally smaller. Consequently,
changes in prevailing interest rates may not have a similar effect, or may  have
a  similar  effect,  but  to  a  smaller  degree,  on  the  prepayment  rates on
manufactured housing contracts.
 
    The percentages  and weighted  average lives  in the  following tables  were
determined  using the following assumptions  (the "Structuring Assumptions") (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 Servicer does not  exercise
its  right  of  optional  termination  described above  but  the  Trust  Fund is
terminated pursuant to a Termination Auction as described in "Description of the
Certificates -- Optional Termination and Termination Auction" herein, (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-1 Certificates  initially represent
9.73% of the entire ownership  interest in the Trust Fund  and have a Class  A-1
Pass-Through  Rate of  5.910% per  annum, the  Class A-2  Certificates initially
represent 6.87% of the entire  ownership interest in the  Trust Fund and have  a
Class  A-2 Pass-Through  Rate of  6.015% per  annum, the  Class A-3 Certificates
initially represent 7.82% of the entire ownership interest in the Trust Fund and
have a  Class  A-3  Pass-Through  Rate  of  6.060%  per  annum,  the  Class  A-4
Certificates  initially represent 11.26% of the entire ownership interest in the
Trust Fund and have a Class A-4 Pass-Through Rate of 6.195% per annum, the Class
A-5 Certificates initially represent 5.46%  of the entire ownership interest  in
the  Trust Fund and have a Class A-5  Pass-Through Rate of 6.265% per annum, the
Class A-6  Certificates  initially  represent  5.92%  of  the  entire  ownership
interest  in the Trust Fund and have a Class A-6 Pass-Through Rate of 6.340% per
annum, the  Class A-7  Certificates  initially represent  15.00% of  the  entire
ownership  interest in the Trust Fund and  have a Class A-7 Pass-Through Rate of
6.580% per

annum, the  Class  A-8 Certificates  initially  represent 9.92%  of  the  entire
ownership  interest in the Trust Fund and  have a Class A-8 Pass-Through Rate of
6.725% per annum, the Class A-9  Certificates initially represent 10.51% of  the
entire  ownership interest in the  Trust Fund and have  a Class A-9 Pass-Through
Rate of 7.015% per annum, the Class M Certificates initially represent 8.50%  of
the  entire ownership interest in the Trust Fund and have a Class M Pass-Through
Rate of 6.800%  per annum  and the  Class B-1  Certificates initially  represent
6.00%  of the entire ownership  interest in the Trust Fund  and have a Class B-1
Pass-Through Rate of 6.940% per annum, (v) no interest shortfalls will arise  in
connection  with prepayment  in full  of the  Contracts, (vi)  there will  be no
repurchases of any  Contracts due to  a breach in  a representation or  warranty
with  respect thereto, and (vii) a servicing fee of 1.00% per annum will be paid
to the Servicer. The tables assume that there are no losses or delinquencies  on
the  Contracts. No  representation is made  that losses or  delinquencies on the
Contracts will be experienced at the  rate assumed in the preceding sentence  or
at any other rate.

    Since  the  tables  were  prepared  on the  basis  of  the  assumptions (the
"Structuring Assumptions") in the  preceding paragraph, there are  discrepancies
between  the characteristics of the actual  Contracts and the characteristics of
the Contracts assumed in preparing the tables. Any such discrepancy may have  an
effect  upon the percentages of the Initial Certificate Balance of each Class of
Offered Certificates outstanding and weighted average lives of such Certificates
set forth in the tables. In addition,  since the actual Contracts and the  Trust
Fund  have  characteristics which  differ from  those  assumed in  preparing the
tables  set  forth  below,  the  distributions  of  principal  on  the   Offered
Certificates may be made earlier or later than as indicated in the tables.
 
    It  is not likely that  Contracts will prepay at  any constant percentage of
the Prepayment Model to maturity or that  all Contracts will prepay at the  same
rate.  In addition,  the diverse  remaining terms  to maturity  of the Contracts
(which include recently originated Contracts) could produce slower distributions
of principal than  indicated in  the tables at  the various  percentages of  the
Prepayment  Model  specified  even if  the  weighted average  remaining  term to
maturity of the Contracts is 277 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 Structuring  Assumptions, the  following tables  indicate  the
resulting  weighted average lives of the Offered Certificates and sets forth the
percentage of the Initial Class A-1  Certificate Balance, the Initial Class  A-2
Certificate  Balance,  the Initial  Class A-3  Certificate Balance,  the Initial
Class A-4 Certificate Balance,  the Initial Class  A-5 Certificate Balance,  the
Initial  Class  A-6  Certificate  Balance,  the  Initial  Class  A-7 Certificate
Balance, the  Initial  Class A-8  Certificate  Balance, the  Initial  Class  A-9
Certificate  Balance, the Initial  Class M Certificate  Balance, and the Initial
Class B-1 Certificate Balance that would be outstanding after each of the  dates

FINAL SCHEDULED DISTRIBUTION DATE
 
    The   Final  Scheduled  Distribution   Dates  for  each   Class  of  Offered
Certificates is set forth on the cover hereof. The Final Scheduled  Distribution
Dates  for the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-6,
Class A-7, Class A-8 and Class B-1 Certificates were determined on the basis  of
the  Structuring Assumptions and  the assumption that  there are no prepayments,
the Servicer does not exercise its optional termination right and the  Contracts
are  not sold in  a Termination Auction. The  Final Scheduled Distribution Dates
for the Class A-9 and Class M Certificates were determined by adding six  months
to  the date of  maturity of the  latest possible maturing  Contract. The actual
final Distribution Date for each Class  of Offered Certificates is likely to  be
shorter,  and  could  occur  significantly earlier  than,  the  applicable Final
Scheduled Distribution Date because  (i) prepayments are  likely to occur,  (ii)
the  Seller may repurchase Contracts in the event of breaches of representations
and warranties and (iii) the Servicer  may cause an optional termination of  the
Trust Fund or a Termination Auction may occur.

                        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,  unless  the  context
otherwise provides.
 
    Set forth below are summaries of the specific terms and provisions  pursuant
to which the Certificates will be issued. The following summaries do not purport
to  be  complete and  are subject  to, and  are qualified  in their  entirety by
reference to, the  provisions of  the Agreement. When  particular provisions  or
terms  used in the  Agreement are referred to,  the actual provisions (including
definitions of terms) are incorporated by reference.
 
GENERAL
 
    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 Chicago, Illinois 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 Certificate of a Class is the percentage
obtained  from dividing  the original  denomination of  such Certificate  by the
Initial Certificate Balance of the Certificates of that class.
 
    The Trust Fund includes (i) the  Contract Pool, including certain rights  to
receive  payments  on the  Contracts on  and  after the  Cut-off Date,  (ii) the
amounts held from time to time in the "Certificate Account" (as described  below
under  "-- Payment on Contracts; Certificate Account") maintained by the Trustee
pursuant to the Agreement, (iii) any property which initially secured a Contract
and which is acquired in the process of realizing thereon, (iv) the  obligations
of  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,  (v) the proceeds of all insurance
policies described herein and (vi) the Reserve Account.
 
    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
 
                                      S-49
<PAGE>
"Distribution Date") beginning in August 1997, to the persons in whose names the
Certificates  are registered at the  close of business on  the last business day
preceding each Distribution Date (the "Record Date").

    The Class A-4 Pass-Through Rate will be 6.195% per annum.
 
    The Class A-5 Pass-Through Rate will be 6.265% per annum.
 
    The Class A-6 Pass-Through Rate will be 6.340% per annum.
 
    The Class A-7 Pass-Through Rate will be 6.580% per annum.
 
    The Class A-8 Pass-Through Rate will be 6.725% per annum.
 
    The Class M Pass-Through Rate will be 6.800% per annum.
 
    The Class B-1 Pass-Through Rate will be 6.940% per annum.
 
    The Pass-Through Rate for  each of the Certificates  of Class A-9 and  Class
B-2  on any Distribution Date will be adjusted  so as not to exceed the weighted
average of the Net Contract Rates of  the Contracts in the Contract Pool at  the
beginning  of the month preceding the month  of such Distribution Date. The "Net
Contract Rate" of a Contract equals the rate of interest borne by such  Contract
minus the Annual Servicing Rate. The "Annual Servicing Rate" is equal to 1%. The
weighted  average Net Contract Rate of the  Contract Pool as of the Cut-off Date
was approximately 9.72%.
 
    The Class A-9 Pass-Through Rate on each Distribution Date will be 7.015% per
annum, subject  to a  maximum rate  equal to  the weighted  average of  the  Net
Contract Rates on the Contracts in the Contract Pool, computed on the basis of a
360-day  year of twelve  30-day months. In  all but the  most unusual prepayment
scenarios, it  is anticipated  that  the Class  A-9  Pass-Through Rate  will  be
7.015%.  If a large principal amount of Contracts having Contract Rates equal to
or higher than 8.015% were to  prepay while a proportionate principal amount  of
the  Contracts having Contract Rates lower than  8.015% did not prepay, with the
result that  the  interest  collections  on the  remaining  Contracts  were  not
sufficient  to support a Class  A-9 Pass-Through Rate of  7.015%, then the Class
A-9 Pass-Through Rate would be equal to the weighted average of the Net Contract
Rates on the Contracts remaining in the Contract Pool. Of the initial Contracts,
97.79% by aggregate principal balance as of the Cut-off Date had Contract  Rates
equal to or higher than 8.015%.
 
    The Class B-2 Pass-Through Rate on each Distribution Date will be 7.700% per
annum,  subject  to a  maximum rate  equal to  the weighted  average of  the Net
Contract Rates on the Contracts in the Contract Pool, computed on the basis of a
360-day year of  twelve 30-day months.  In all but  the most unusual  prepayment
scenarios,  it  is anticipated  that  the Class  B-2  Pass-Through Rate  will be
7.700%. If a large principal amount of Contracts having Contract Rates equal  to
or  higher than 8.700% were to prepay  while a proportionate principal amount of
the Contracts having Contract Rates lower  than 8.700% did not prepay, with  the
result  that  the  interest  collections on  the  remaining  Contracts  were not
sufficient to support a  Class B-2 Pass-Through Rate  of 7.700%, then the  Class
B-2 Pass-Through Rate would be equal to the weighted average of the Net Contract
Rates on the Contracts remaining in the Contract Pool. Of the initial Contracts,
89.83%  by aggregate principal balance as of the Cut-off Date had Contract Rates
equal to or higher than 8.700%.
 
CONVEYANCE OF CONTRACTS
 
    On the date  of initial  issuance of the  Certificates, BankAmerica  Housing
Services  will convey  to the  Trustee, without  recourse, all  right, title and
interest of 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-
 
                                      S-50
<PAGE>
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  BankAmerica  Housing  Services  or
replaced  with another Contract,  except that if the  discrepancy relates to the
principal balance of  a Contract  (determined as  described above),  BankAmerica
Housing  Services may, under certain conditions, deposit cash in the Certificate
Account in an amount sufficient to offset such discrepancy. The Trustee will not
review the Contract Files.
 
    The Servicer will hold, as custodian and agent on behalf of the Trustee, the
original Contracts  and copies  of documents  and instruments  relating to  each
Contract  and the security interest in the Manufactured Home, and real property,
if any, relating to  each Contract. See "Risk  Factors -- Security Interests  in
the  Manufactured  Homes;  Transfer  of Contracts  and  Security  Interests" and
"Certain Legal Aspects of  the Contracts --  Security Interests in  Manufactured
Homes"  and  "-- Land  Home and  Land-in-Lieu Contracts"  in the  Prospectus for
discussion of the  consequences of  the Servicer maintaining  possession of  the
original  Contracts and the security interest  in the related Manufactured Homes
and real property, if any, securing such  Contracts. In order to give notice  of
the  Trustee's  right, title  and  interest in  and  to the  Contracts,  a UCC-1
financing statement identifying the Trustee as the secured party and identifying
all the Contracts as collateral will be  filed in the appropriate office in  the
appropriate states. The Contracts will be stamped or otherwise marked to reflect
their  assignment  to the  Trustee.  To the  extent  that the  Contracts  do not
constitute "chattel paper" within  the meaning of  the UCC as  in effect in  the
applicable  jurisdictions  or to  the extent  that  the Contracts  do constitute
chattel paper and a subsequent purchaser is able to take physical possession  of
the  Contracts without notice of such  assignment, the Trustee's interest in the
Contracts could be defeated. See "Certain Legal Aspects of the Contracts" in the
Prospectus.
 
    BankAmerica  Housing  Services   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)

(ii)  originated by BankAmerica  Housing Services in the  ordinary course of its
business; (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

(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 and real property,
 
                                      S-51
<PAGE>
if any, securing such Contract, (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 and real property,  if
any,  securing such Contract, (l)  such Contract has not  been sold, assigned or
pledged to any other person, and prior  to the transfer of the Contracts to  the
Trustee,  BankAmerica Housing  Services 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 BankAmerica Housing  Services has not waived  any of the foregoing;
(n) as of the Closing Date (as  defined below), there were, to the knowledge  of
BankAmerica Housing Services' no liens or claims which have been filed for work,
labor  or  materials affecting  a Manufactured  Home or  real property,  if any,
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

the knowledge of BankAmerica Housing Services 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,  Bank of America, FSB was 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 will be
stamped to indicate its assignment to the Trustee within 60 days of the  Closing
Date  and (y) the Contract with the lowest  Contract Rate has a Contract Rate of
8.00% and the Contract  with the highest  Contract Rate has  a Contract Rate  of
13.50%.  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,  BankAmerica Housing
Services will be  obligated to  repurchase, at  the price  described below,  any
Contract  sold by it  within 90 days after  BankAmerica Housing Services becomes
aware, or after BankAmerica Housing Services' receipt of written notice from the
Trustee or  the Servicer,  of a  breach  of any  representation or  warranty  of
BankAmerica  Housing  Services 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, BankAmerica  Housing  Services will  not be
required to repurchase  or substitute  any Contract relating  to a  Manufactured
Home  and  real  property,  if  any,  securing  such  Contract  located  in  any
jurisdiction on account of a breach of the representation and warranty described
in clause (k) above solely  on the basis of  the failure by BankAmerica  Housing
Services to cause a notation to be made on any document of title relating to any
such  Manufactured Home  or to execute  any transfer instrument  relating to any
such Manufactured  Home or  real property,  if  any (other  than a  notation  or
transfer instrument necessary to show 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
 
                                      S-52
<PAGE>
laws  regarding the perfection  of security interests  therein applicable to the
Manufactured Homes located in such jurisdiction  and (B) the Servicer shall  not
have completed all appropriate remedial action with respect to such Manufactured
Home  within 180 days after receipt of such written advice. Any such advice will
be from counsel  selected by  the Servicer  on a  non-discriminatory basis  from
among  the  counsel  used  by  the  Servicer  in  its  general  business  in the
jurisdiction in question. The Servicer will  have no ongoing obligation to  seek
advice  with respect to the matters described in clause (ii) above. However, the
Servicer is  required to  seek  advice with  respect  to such  matters  whenever
information  comes to the attention of its  counsel which causes such counsel to
determine that a holding of the type described in clause (ii)(A) might exist. If
any counsel selected by the Servicer informs the Servicer that no holding of the
type described in  clause (ii)(A)  exists, such  advice will  be conclusive  and
binding  on the  parties to  the Agreement  pursuant to  which a  Trustee has an
interest in any Contracts  in the applicable jurisdiction  as of the  applicable
date.  If any  holding described  above which  would give  rise to  a repurchase
obligation on  the part  of BankAmerica  Housing Services  were to  result  from
proceedings  brought  by  a  receiver  or  conservator  of  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 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  will be required  to deposit in the
Certificate Account cash in the amount, if any, by which the Scheduled Principal
Balance of the  Replaced Contract  as of  the beginning  of the  month in  which
substitution takes place exceeds the Scheduled Principal Balance of the Contract
it sold being substituted as of the beginning of the month.
 
PAYMENTS ON THE CONTRACTS; CERTIFICATE ACCOUNT
 
    The   Trustee  will  initially  establish   and  maintain  an  account  (the
"Certificate Account") at a depository  institution organized under the laws  of
the  United States or any  state, the deposits of which  are insured to the full
extent permitted  by  law by  the  Federal Deposit  Insurance  Corporation  (the
"FDIC") whose commercial paper, long-term deposits or long-term unsecured senior
debt  has a rating of P-1 by Moody's and F-1 by Fitch (if rated by Fitch) in the
case of commercial  paper or  in one  of the  two highest  rating categories  by
Moody's  and Fitch  (if rated  by Fitch)  in the  case of  long-term deposits or
long-term unsecured senior debt, and which is subject to examination by  federal
or state authorities or a depository institution otherwise acceptable to Moody's
and  Fitch (an "Eligible Institution"). The funds in the Certificate Account are
required to  be  invested by  the  Trustee  in common  trust  funds,  collective
investment  trusts or Eligible  Investments that will mature  not later than the
business day preceding the applicable Distribution Date. "Eligible  Investments"
include,  among other  investments, obligations of  the United States  or of any
agency thereof  backed  by the  full  faith and  credit  of the  United  States;
certificates of deposit, time deposits and bankers' acceptances sold by eligible
financial institutions;
 
                                      S-53
<PAGE>
commercial  paper rated  P-1 by Moody's  and F-1  by Fitch (if  rated by Fitch);
money market funds  acceptable to Moody's  and Fitch (as  evidenced by a  letter
from  Moody's and  Fitch to  such effect);  and other  obligations acceptable to
Moody's and Fitch.
 
    All payments in respect of principal and interest on the Contracts  received
during  any Collection Period  by the Servicer  (exclusive of Scheduled Payments
due  prior  to  the  Cut-off  Date),  including  Liquidation  Proceeds  (net  of
Liquidation  Expenses,  as defined  below),  are required  to  be paid  into the
Certificate Account not  later than  the second business  day following  receipt
thereof.  Amounts received as late payment fees, extension fees, assumption fees
or similar fees may be retained by  the Servicer as part of its servicing  fees.
See  " -- Servicing Compensation; Certain  Other Matters Regarding the Servicer"
below. In addition,  the amount  paid by  BankAmerica Housing  Services 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  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 1997-1 Regular Certificates will
be applied  first to  the holders  of  the Senior  Certificates, second  to  the
holders  of the  Class M Certificates  and third to  the holders of  the Class B
Certificates. The Available Distribution Amount for each Distribution Date  will
be  applied  in  the  amounts  and  the  order  of  priority  set  forth  below.
Distributions 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 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.
 
    The percentages  of  the  Formula Principal  Distribution  Amount  that  are
distributable  to the Senior Certificateholders, the Class M Certificateholders,
the Class  B-1  Certificateholders  and the  Class  B-2  Certificateholders  are
determined  on the basis of  whether the Class M  Principal Distribution Test or
the Class B Principal  Distribution Test are met,  as described below. By  their
terms, neither of such tests can be met prior to the Distribution Date in August
2001.  Consequently, unless  the Senior Certificate  Balance is  reduced to zero
prior to such Distribution Date, holders of the Senior Certificates will receive
100% of the Formula Principal Distribution Amount (in the order described below)
until at least such Distribution Date.
 
    PRIORITIES.  On each Distribution  Date, the Available Distribution  Amount,
together  with the Reserve Account Draw Amount (as defined herein), if any, will

           the Class A-1 Certificates is reduced to zero;
 
       (b) to the Class A-2 Certificateholders until the Certificate Balance  of
           the Class A-2 Certificates is reduced to zero;
 
       (c) to  the Class A-3 Certificateholders until the Certificate Balance of
           the Class A-3 Certificates is reduced to zero;
 
       (d) to the Class A-4 Certificateholders until the Certificate Balance  of
           the Class A-4 Certificates is reduced to zero;
 
       (e) to  the Class A-5 Certificateholders until the Certificate Balance of
           the Class A-5 Certificates is reduced to zero;

           the Class A-7 Certificates is reduced to zero;
 
       (h) to the Class A-8 Certificateholders until the Certificate Balance  of
           the Class A-8 Certificates is reduced to zero; and
 
           (i)
           to  the Class A-9 Certificateholders until the Certificate Balance of
           the Class A-9 Certificates is reduced to zero;
 
         (iii)
           to the Class M Certificateholders, the Class M Interest  Distribution
           Amount;
 
          (iv)
           to  the Class  M Certificateholders,  the Class  M Percentage  of the
           Formula Principal Distribution Amount  until the Class M  Certificate
    Balance is reduced to zero;
 
           (v)
           to   the  Class  B-1  Certificateholders,   the  Class  B-1  Interest
           Distribution Amount;
 
          (vi)
           to the Class B-1  Certificateholders, the Class  B Percentage of  the
           Formula Principal Distribution Amount until the Class B-1 Certificate
    Balance is reduced to zero;
 
         (vii)
           to   the  Class  B-2  Certificateholders,   the  Class  B-2  Interest
           Distribution Amount;
 
        (viii)
           to the Class B-2  Certificateholders, the Class  B Percentage of  the
           Formula  Principal  Distribution  Amount  (less  any  portion thereof
    distributed pursuant to clause (vi)  above) until the Class B-2  Certificate
    Balance is reduced to zero;
 
          (ix)
           if  such Distribution  Date is  on or  after the  earlier of  (a) the
           Distribution Date in August 2007 and (b) the first Distribution  Date
    on  which the percentage equivalent of a fraction, the numerator of which is
    the Pool Scheduled Principal Balance  (after giving effect to  distributions
    with respect to principal) for such Distribution Date and the denominator of
    which  is the Cut-off Date Pool Principal  Balance, is less than or equal to
    25%, to the Reserve Account, any remaining Available Distribution Amount  to
    the  extent necessary to  increase the funds  in the Reserve  Account to the
    Reserve Account Cap; and
 
           (x)
           to  the   Class  R   Certificateholders,  any   remaining   Available
           Distribution Amount.
 
    Notwithstanding  the foregoing, on any Distribution Date on which the amount
distributable  (the  "initial  distribution")  to  holders  of  the  Class   B-2
Certificates  pursuant to clause (viii) above would cause (x) the sum of (i) the
Class B-2 Certificate  Balance and  (ii) the amount  on deposit  in the  Reserve
Account  (in each case,  after giving effect to  the initial distribution) (such
sum, the  "Clause X  Amount") to  be less  than (y)  $5,239,906 (the  "Clause  Y
Amount"),  which is  2% of  the Cut-off  Date Pool  Principal Balance,  then the
principal distribution  to holders  of the  Class B-2  Certificates pursuant  to
clause  (viii) above will be  reduced to such amount as  will cause the Clause X
Amount to  equal the  Clause Y  Amount, and  the Available  Distribution  Amount
(allocable  to principal)  that remains after  such reduced  distribution to the
Class B-2 Certificateholders  will be  distributed PRO  RATA to  holders of  the
Senior  Certificates  and  the  Class  M  Certificates  on  the  basis  of their
respective Certificate Balances.
 
    In addition, notwithstanding the prioritization  of the distribution of  the
Formula  Principal Distribution Amount to the holders of the Senior Certificates
pursuant to clause (ii)  above, on a  Distribution Date, if  any, in respect  of
which  a  Deficiency Event  (defined below)  is  in effect,  the portion  of the
Formula Principal  Distribution Amount  for such  Distribution Date  that  would
otherwise  be distributed sequentially  to the Class A-1,  Class A-2, Class A-3,
Class  A-4,  Class  A-5,  Class  A-6,  Class  A-7,  Class  A-8  and  Class   A-9
Certificateholders  pursuant to clause (ii) above will instead be distributed to
the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-6, Class A-7,
Class A-8 and Class A-9 Certificateholders  PRO RATA based upon the  Certificate
Balance  of each such Class until each  of the Certificate Balances of the Class
A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-6, Class A-7, Class A-8
and
 
                                      S-56
<PAGE>
Class A-9 Certificates have been reduced  to zero. A "Deficiency Event" will  be
in  effect for any  Distribution Date as  to which the  Pool Scheduled Principal
Balance is equal to or less than the aggregate Certificate Balance of the  Class
A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-6, Class A-7, Class A-8
and Class A-9 Certificates.
 
    Furthermore, notwithstanding the foregoing, if the percentage of the Formula
Principal  Distribution  Amount  allocable  to  the  holders  of  the  Class A-9
Certificates on any Distribution Date pursuant to clause (ii) above exceeds  the
Class  A-9 Certificate Balance  for such Distribution Date,  such excess will be
distributed to the Class  M and Class B-1  Certificateholders (or the Class  B-2
Certificateholders  if the Certificate Balance of the Class B-1 Certificates has
been reduced  to  zero) PRO  RATA  on the  basis  of the  Class  M and  Class  B
Percentages,   respectively.  If   the  percentage  of   the  Formula  Principal
Distribution  Amount  allocable  to  the  Class  M  Certificateholders  on   any
Distribution  Date pursuant to clause (iv) above exceeds the Class M Certificate
Balance for any such Distribution Date,  such excess will be distributed to  the
Class  B-1 Certificateholders until the Class B-1 Certificate Balance is reduced
to zero (and to the Class B-2 Certificateholders thereafter).
 
    DEFINITIONS.   As  to  any Distribution  Date,  the  "Interest  Distribution
Amount"  for any Class  is equal to the  sum of (i) one  month's interest at the
Pass-Through Rate for that  Class on the Certificate  Balance of that Class  and
(ii)   any  previously   undistributed  shortfalls   in  interest   due  to  the
Certificateholders of that  Class in  respect of prior  Distribution Dates.  Any
shortfall  in interest  due to  Certificateholders will,  to the  extent legally
permissible, bear  interest  at the  related  Pass-Through Rate.  Interest  will
accrue  with respect to each  Distribution Date in respect  of the Series 1997-1
Regular Certificates during the  one-month period beginning on  the 10th day  of
the  month preceding the month  of such Distribution Date  and ending on the 9th
day of the month of such Distribution Date.
 
    The "Senior  Percentage"  (which shall  not  be  greater than  100%)  for  a
Distribution  Date is the percentage equivalent  of a fraction, the numerator of
which is the Senior Certificate  Balance immediately prior to such  Distribution
Date and the denominator of which is the sum of:
 
           (i)
           the Senior Certificate Balance immediately prior to such Distribution
           Date,
 
          (ii)
           if  the Class M Principal Distribution Test has been met, the Class M
           Certificate Balance immediately prior  to such Distribution Date  or,
    if the Class M Principal Distribution Test has not been met, zero, and
 
         (iii)
           if  the Class B Principal Distribution Test has been met, the Class B
           Certificate Balance immediately prior  to such Distribution Date  or,
    if the Class B Principal Distribution Test has not been met, zero.
 
    The  "Class  M Percentage"  (which shall  not  be greater  than 100%)  for a
Distribution Date is (i) if the Class M Principal Distribution Test has been met
or the  Senior Certificate  Balance  is zero  for  such Distribution  Date,  the
percentage  equivalent of  a fraction,  the numerator  of which  is the  Class M
Certificate  Balance  immediately  prior  to  such  Distribution  Date  and  the
denominator of which is the sum of:
 
       (a) the Senior Certificate Balance immediately prior to such Distribution
           Date,
 
       (b) the   Class  M   Certificate  Balance   immediately  prior   to  such
           Distribution Date, and
 
       (c) if the Class B Principal Distribution Test has been met, the Class  B
           Certificate  Balance immediately prior to such Distribution Date, or,
    if the Class B Principal Distribution Test has not been met, zero,
 
or (ii) if  the Class M  Principal Distribution Test  has not been  met and  the
Senior Certificate Balance is not zero for such Distribution Date, zero.
 
    The  "Class  B Percentage"  (which shall  not  be greater  than 100%)  for a
Distribution Date is (i) if the Class B Principal Distribution Test has been met
or the Senior Certificate Balance and the Class M
 
                                      S-57
<PAGE>
Certificate  Balance  are  zero  for  such  Distribution  Date,  the  percentage
equivalent  of a  fraction, the  numerator of which  is the  Class B Certificate
Balance immediately prior to such Distribution Date and the denominator of which
is the sum of:
 
       (a) the Senior Certificate Balance immediately prior to such Distribution
           Date,
 
       (b) the  Class   M  Certificate   Balance  immediately   prior  to   such
           Distribution Date, and
 
       (c) the   Class  B   Certificate  Balance   immediately  prior   to  such
           Distribution Date,
 
or (ii) if  the Class B  Principal Distribution Test  has not been  met and  the
Senior  Certificate Balance and the Class M Certificate Balance are not zero for
such Distribution Date, zero.
 
    Notwithstanding the foregoing, in no event  will (i) the Class M  Percentage
exceed  the percentage  equal to  100% minus the  Senior Percentage  or (ii) the
Class B Percentage  exceed the percentage  equal to  100% minus the  sum of  the
Senior Percentage and the Class M Percentage.
 
    The  Class M Principal Distribution Test will be met if all of the following
conditions are satisfied:
 
       (1) the Distribution Date is on or after the Distribution Date in  August
           2001;
 
       (2) the  percentage equivalent of  a fraction, the  numerator of which is
           the sum of (a) the Class  M Certificate Balance immediately prior  to
    such  Distribution Date and (b) the  Class B Certificate Balance immediately
    prior to such  Distribution Date and  the denominator of  which is the  Pool
    Scheduled  Principal Balance immediately prior to such Distribution Date, is
    equal to at least  26.25% (which is 1.5  times the percentage equivalent  of
    the  fraction, the numerator of which is the  sum of (a) the Initial Class M
    Certificate Balance, (b) the Initial  Class B-1 Certificate Balance and  (c)
    the  Initial Class B-2  Certificate Balance and the  denominator of which is
    the Cut-off Date Pool Principal Balance);
 
       (3) The Cumulative Realized Losses  as of such  Distribution Date do  not
           exceed  (a) if  such Distribution Date  is from  and including August
    2001 and  up to  and including  July 2002,  6.0% of  the Cut-off  Date  Pool
    Principal  Balance,  (b) if  such Distribution  Date  is from  and including
    August 2002 and up to and including July 2003, 7.0% of the Cut-off Date Pool
    Principal Balance,  (c) if  such  Distribution Date  is from  and  including
    August 2003 and up to and including July 2004, 8.5% of the Cut-off Date Pool
    Principal  Balance, and (d) if such Distribution  Date is in or after August
    2004, 9.5% of the Cut-off Date Pool Principal Balance;
 
       (4) the Current Realized Loss Ratio as of such Distribution Date does not
           exceed 2.5%;
 
       (5) the Average Sixty-Day Delinquency Ratio as of such Distribution  Date
           does not exceed 3.5%; and
 
       (6) the Average Thirty-Day Delinquency Ratio as of such Distribution Date
           does not exceed 5.5%.
 
    The  Class B Principal Distribution Test will be met if all of the following
conditions are satisfied:
 
       (1) the Distribution Date is on or after the Distribution Date in  August
           2001;
 
       (2) the  percentage equivalent of  a fraction, the  numerator of which is
           the  Class   B  Certificate   Balance  immediately   prior  to   such
    Distribution  Date  and  the  denominator  of  which  is  the  Pool Schedule
    Principal Balance immediately prior to  such Distribution Date, is equal  to
    at  least 13.50% (which is approximately 1.5 times the percentage equivalent
    of the fraction, the numerator of which is the sum of (a) the Initial  Class
    B-1  Certificate Balance and  (b) the Initial  Class B-2 Certificate Balance
    and the denominator of which is the Cut-off Date Pool Principal Balance);
 
       (3) The Cumulative Realized Losses  as of such  Distribution Date do  not
           exceed  (a) if such Distribution Date is from and including July 2002
    and up to and including 6.0% of the Cut-off Date Pool Principal Balance, (b)
    if such Distribution Date is  from and including August  2002 and up to  and
    including July 2003, 7.0% of the Cut-off Date Pool Principal Balance, (c) if
    such Distribution Date is
 
                                      S-58
<PAGE>
    from  and including August 2003  and up to and  including July 2004, 8.5% of
    the Cut-off Date Pool Principal Balance and (d) if such Distribution Date is
    on or after August 2004, 9.5% of the Cut-off Date Pool Principal Balance.
 
       (4) the Current Realized Loss Ratio as of such Distribution Date does not
           exceed 2.5%;
 
       (5) the Average Sixty-Day Delinquency Ratio as of such Distribution  Date
           does not exceed 3.5%; and
 
       (6) the Average Thirty-Day Delinquency Ratio as of such Distribution Date
           does not exceed 5.5%.
 
    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
BankAmerica Housing Services on account  of certain breaches of  representations
and  warranties  made by  it  in the  Agreement,  (iii) all  partial prepayments
received during such  related Collection  Period, (iv)  the Scheduled  Principal
Balance of each Contract that was prepaid in full during such related Collection
Period  and (v) the Scheduled  Principal Balance of each  Contract that became a
Liquidated Contract (defined below) during such related Collection Period.
 
    The "Scheduled Principal Balance" of a Contract for any Distribution Date is
its principal balance as  of the Due Date  in the Collection Period  immediately
preceding  such Distribution Date,  after giving effect  to all previous partial
prepayments, all previous scheduled principal payments (whether or not paid) and
the scheduled principal payment due on such Due Date, but without giving  effect
to  any  adjustment due  to bankruptcy  or  similar proceedings.  The "Scheduled
Principal  Reduction  Amount"  for  any  Distribution  Date  is  an  approximate
calculation  (performed  on an  aggregate basis  rather  than on  a Contract-by-
Contract basis) of the  scheduled payments of principal  due during the  related
Collection Period. Both of these terms are more fully described herein under "--
Distributions" above.
 
    The "Pool Scheduled Principal Balance" for any Distribution Date is equal to
the  Cut-off Date Pool Principal Balance less the aggregate of the Total Regular
Principal Amounts for all prior Distribution Dates.
 
    In general, a "Liquidated Contract" is a defaulted Contract as to which  all
amounts  that  the  Servicer  expects  to  recover  relating  to  such  Contract
("Liquidation Proceeds") have been received. A Liquidated Contract includes  any
defaulted  Contract in respect  of which the related  Manufactured Home has been
realized upon and  disposed of and  the proceeds of  such disposition have  been
received.
 
    The  "Certificate Balance" for any Class as  of any Distribution Date is the
Initial  Certificate  Balance  of  that   Class  less  all  amounts   previously
distributed  to Certificateholders  of that Class  on account  of principal. The
"Senior Certificate  Balance" as  of any  Distribution Date  is the  sum of  the
Certificate  Balances  of  the  Senior Certificates  immediately  prior  to such
Distribution Date. The "Subordinate Certificate Balance" as of any  Distribution
Date  is the sum of  the Class M Certificate  Balance, the Class B-1 Certificate
Balance and  the  Class  B-2  Certificate  Balance  immediately  prior  to  such
Distribution  Date. The term "Certificate Balance" in respect of any one or more
Classes of Certificates  has the corresponding  meaning. In no  event shall  the
aggregate distributions of principal to the holders of the Class A-1, Class A-2,
Class  A-3, Class A-4,  Class A-5, Class  A-6, Class A-7,  Class A-8, Class A-9,
Class M,  Class B-1  and Class  B-2 Certificates  exceed the  Initial Class  A-1
Certificate  Balance,  the Initial  Class A-2  Certificate Balance,  the Initial
Class A-3 Certificate Balance,  the Initial Class  A-4 Certificate Balance,  the
Initial  Class  A-5  Certificate  Balance,  the  Initial  Class  A-6 Certificate
Balance, the  Initial  Class A-7  Certificate  Balance, the  Initial  Class  A-8
Certificate  Balance,  the Initial  Class A-9  Certificate Balance,  the Initial
Class M Certificate Balance, the Initial  Class B-1 Certificate Balance and  the
Initial Class B-2 Certificate Balance, respectively.

<PAGE>
    The  "Average  Sixty-Day  Delinquency  Ratio"  and  the  "Average Thirty-Day
Delinquency Ratio" are, in general, the  ratios of the average of the  aggregate
principal  balances of Contracts delinquent 60 days or more and 30 days or more,
respectively, for the preceding three  Collection Periods (determined as of  the
last day of each such Collection Period) to the average Pool Scheduled Principal
Balance  for such  periods. "Cumulative  Realized Losses"  are, in  general, the
aggregate net liquidation losses (calculated  as specified in the Agreement)  in
respect  of Liquidated Contracts  since the Cut-off  Date. The "Current Realized
Loss Ratio" is, in general, the ratio of the aggregate net liquidation losses in
respect of Liquidated Contracts for the periods specified in the Agreement to an
average Pool Scheduled Principal Balance specified in the Agreement.
 
RESERVE ACCOUNT
 
    On the Closing Date,  the Trustee shall establish  an account (the  "Reserve
Account")  for the benefit of the  Certificateholders. The Reserve Account shall
have an  initial  balance  of  zero  on the  Closing  Date.  Commencing  on  the
Distribution  Date which is the  earlier of (a) the  Distribution Date in August
2007 and (b) the first Distribution Date on which the percentage equivalent of a
fraction, the numerator of which is the Pool Scheduled Principal Balance  (after
giving  effect to distribution with respect  to principal) for such Distribution
Date and the denominator of which is the Cut-off Date Pool Principal Balance, is
less than or equal  to 25%, the  Trustee shall make a  deposit into the  Reserve
Account  pursuant to clause  (ix) in the  fourth paragraph under "Distributions"
above up to the Reserve Account Cap. On each Distribution Date, the Trustee will
withdraw from the Reserve Account an amount (the "Reserve Account Draw  Amount")
equal to the lesser of (a) the amount then on deposit in the Reserve Account and
(b)  the amount by which  the aggregate of amounts  due to Certificateholders in
clauses (i) through  (viii) under  "Distributions" above  exceeds the  Available
Distribution  Amount  on  such  Distribution Date  and  distribute  such amount,
together with the Available Distribution Amount.
 
    Funds in the  Reserve Account will  be invested in  Eligible Investments  as
directed  by the Trustee, and the net  investment earnings, if any, will be paid
to the  Class R  Certificateholders. "Eligible  Investments" means  one or  more
common   trust  funds,  collective  investment  trusts  or  money  market  funds
acceptable to Moody's and Fitch (as evidenced by a letter from Moody's and Fitch
to such effect  or, if no  such trusts or  funds are acceptable  to Moody's  and
Fitch any other obligations acceptable to Moody's and Fitch.
 
    On  any Distribution Date,  any funds on  deposit in the  Reserve Account in
excess of the Reserve  Account Cap (after giving  effect to any Reserve  Account
Draw  Amount paid to the Certificateholders on such date) will be withdrawn from
the Reserve Account and paid to the Class R Certificateholders.
 
    Amounts  paid  to  the  Class  R  Certificateholders  pursuant  to  the  two
immediately  preceding paragraphs will not be  available to offset shortfalls in
distributions to holders of other Classes of Certificates.
 
    The Reserve Account is intended to enhance the likelihood of regular receipt
by the holders of the Series 1997-1  Regular Certificates of the full amount  of
the  distributions due them and to afford such holders protection against losses
on Liquidated Contracts, but no assurance can be given that the Reserve  Account
will be sufficient for such purpose.
 
    The  "Reserve Account Cap" shall  be (i) as to  any Distribution Date (after
giving effect to  distributions due thereon)  after the Closing  Date and  until
none  of the Offered Certificates remain  outstanding, $1,309,976 (which is 0.5%
of the Cut-off Date Pool Principal Balance) and (ii) as to any Distribution Date
(after giving effect  to distributions due  thereon) after none  of the  Offered
Certificates  remain outstanding, the  lesser of the  then outstanding Class B-2
Certificate Balance  and $1,309,976  (which is  0.5% of  the Cut-off  Date  Pool
Principal Balance).
 
SUBORDINATION
 
    The  rights  of  the  holders of  the  Subordinate  Certificates  to receive
distributions of available amounts in the Trust Fund will be subordinate, to the
extent  described   herein,   to   such   rights   of   the   holders   of   the
 
                                      S-60
<PAGE>
Senior Certificates. This subordination is intended to enhance the likelihood of
regular  receipt by the holders of the Senior Certificates of the full amount of
interest  and  principal  distributable  thereon  and  to  afford  such  holders
protection against losses on Liquidated Contracts.
 
    Similarly,  the rights of the holders of the Class B Certificates to receive
distributions due  them  from  available  amounts in  the  Trust  Fund  will  be
subordinated,  to the extent described herein, to  such rights of the holders of
the Class  M Certificates,  and  the rights  of the  holders  of the  Class  B-2
Certificates to receive the distributions due them from available amounts in the
Trust  Fund will be subordinated, to the extent described herein, to such rights
of the holders of  the Class B-1 Certificates.  Subject to the subordination  of
the  Subordinate Certificates to the  Senior Certificates, this subordination of
the Class  B Certificates  to the  Class M  Certificates and  of the  Class  B-2
Certificates  to the Class M  and Class B-1 Certificates  is intended to enhance
the likelihood of regular receipt by the holders of the Class M Certificates and
the holders of the Class B-1  Certificates, respectively, of the full amount  of
the  distributions due them and to afford such holders protection against losses
on Liquidated Contracts.
 
    The protection afforded to  the holders of Senior  Certificates by means  of
the   subordination   of  the   Subordinate   Certificates,  to   the   Class  M
Certificateholders by the subordination of the  Class B Certificates and to  the
Class  B-1 Certificateholders by the subordination of the Class B-2 Certificates
(in each  case, to  the extent  described herein)  will be  accomplished by  the
application  of  the Available  Distribution Amount  (together with  any Reserve
Account Draw  Amount)  in  the  order  specified  under  "Distributions"  above.
Accordingly,  in the event that the Available Distribution Amount (together with
any Reserve Account Draw Amount) on  any Distribution Date is not sufficient  to
permit  the distribution of the amount of  interest and the specified portion of
the Formula Principal  Distribution Amount due  to the holders  of any Class  of
Certificates,  the subordination is intended  to protect such Certificateholders
by the  right  of  such  Certificateholders  to  receive  distributions  of  the
Available  Distribution Amount in respect of  interest and the Formula Principal
Distribution  Amount  that  would  otherwise  have  been  distributable  to  the
Certificateholders  of any Class subordinate in priority of distribution to such
Class, until any shortfall in distributions to the holders of the related senior
Class or Classes of Certificates in  respect thereof has been satisfied, to  the
extent described herein.
 
LOSSES ON LIQUIDATED CONTRACTS
 
    As  described above, the Total Regular Principal Amount distributable to the
holders of  the Series  1997-1 Regular  Certificates on  each Distribution  Date
includes  the  Scheduled  Principal  Balance  of  each  Contract  that  became a
Liquidated Contract  during the  immediately  preceding Collection  Period.  The
Liquidation  Proceeds, net  of (i) certain  expenses incurred  to liquidate such
Liquidated Contract, (ii) all accrued and unpaid interest thereon and (iii)  all
Monthly Advances required to be made in respect of such Liquidated Contract (the
"Net Liquidation Proceeds"), may be less than the Scheduled Principal Balance of
such  Liquidated Contract. Under such circumstances,  the loss on the Liquidated
Contract, in the amount of the  deficiency between the Net Liquidation  Proceeds
and  the Scheduled Principal Balance of such Liquidated Contract, may be covered
to the  extent of  the amount  (the "Excess  Interest"), if  any, by  which  the
interest  collected on nondefaulted Contracts  during the same Collection Period
exceeds interest  distributions due  to  holders of  the Series  1997-1  Regular
Certificates and the Monthly Servicing Fee.
 
    The  effect of any losses on Liquidated Contracts during a Collection Period
in excess of the  (i) Excess Interest, if  any, and (ii) the  funds, if any,  on
deposit  in the Reserve Account  generally will 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-2
Certificateholders,    the   Class   B-1   Certificateholders,   the   Class   M
Certificateholders and the Senior Certificateholders, in that order.

- ------------------------
 
(A) The Cut-off Date Pool Principal Balance on June 30, 1997 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 August 11, 1997. 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 August  11, 1997  are described  under "--
    Payments on Contracts; Certificate Account" above.
 
(C) Distributions on  August 11,  1997  will be  made to  Certificateholders  of
    record at the close of business on August 8, 1997.
 
(D) On  August 6, 1997 (three business days prior to the Distribution Date), the
    Servicer will determine the amounts of principal and interest which will  be
    passed through on August 11, 1997 to Certificateholders.
 
(E) On  August  11, 1997,  the  amounts determined  on  August 6,  1997  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  1997-1  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
 
                                      S-62
<PAGE>
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 1997-1  Regular
Certificateholders rather than to guarantee or insure against losses.
 
    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.

    The Trustee will  include with  each distribution to  a Certificateholder  a

       (m) 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;
 
       (n) the aggregate  principal  balances  of all  Contracts  that  are  not
           Liquidated Contracts and in respect of which the related Manufactured

           by the Trust Fund through the Collection Period immediately preceding
    such Distribution Date, expressed in dollars;
 
       (p) 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;
 
       (q) 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;
 
       (r) the weighted average Net Contract Rate for the Contract Pool for  the
           Collection   Period   immediately   preceding  the   month   of  such
    Distribution Date; and

<PAGE>
       (s) 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
1997-1 Regular Certificate of record at any time during such calendar year as to
the aggregate of amounts reported pursuant to clauses (b) and (c) above for such
calendar year.
 
OPTIONAL TERMINATION AND TERMINATION AUCTION
 
    The Agreement provides that on any Distribution Date after the  Distribution
Date  on which  the Pool  Scheduled Principal  Balance is  less than  10% of the
Cut-off Date  Pool Principal  Balance,  the Servicer  will  have the  option  to
repurchase,  upon giving notice mailed  no later than the  10th day of the month
next preceding  the  month of  the  exercise  of such  option,  all  outstanding
Contracts  at a price  equal to the  greater of (a)  the sum of  (x) 100% of the
Scheduled Principal Balance  of each  Contract (other  than any  Contract as  to
which  the related Manufactured Home  has been acquired and  not yet disposed of
and whose fair market value is included pursuant to clause (y) below) as of  the
final Distribution Date, and (y) the fair market value of such acquired property
(as  determined by the  Servicer), and (b)  the aggregate fair  market value (as
determined by the Servicer) of all of the assets of the Trust Fund, plus, in the
case  of  both  clause   (a)  and  (b),  an   amount  sufficient  to   reimburse
Certificateholders for any shortfall in interest due thereto in respect of prior
Distribution  Dates. Notwithstanding the foregoing,  the Servicer's option shall
not be exercisable  if there  will not  be distributed  to the  holders of  each
outstanding  Class  of  1997-1  Regular  Certificates  an  amount  equal  to the
respective Certificate Balances of such Certificates together with any shortfall
in interest due on such Certificates in respect of prior Distribution Dates  and
one  month's  interest  at  the applicable  Pass-Through  Rates  on  such unpaid
Certificate Balances (collectively, the "Minimum Termination Amount").
 
    On any  Distribution Date  after the  Distribution Date  on which  the  Pool
Scheduled  Principal Balance is less than 10% of the Cut-off Date Pool Principal
Balance, the  Servicer may  also direct  the Trustee  to conduct  a  Termination
Auction for the sale of all Contracts then outstanding in the Trust Fund, and in
any case the Servicer shall be obligated to direct the Trustee to conduct such a
Termination  Auction within 90 days  of the Distribution Date  on which the Pool
Scheduled Principal Balance is less than 10% of the Cut-off Date Pool  Principal
Balance,  unless  the Servicer  has  exercised the  repurchase  option described
above. The Servicer shall give notice mailed no later than 10 days preceding the
date on which any Termination Auction is to occur. The Trustee will solicit each
registered Certificateholder, the Seller and one or more active participants  in
the asset-backed securities or manufactured housing contract market that are not
affiliated  with BankAmerica Corporation to make a bid to purchase the Contracts
at the  Termination Auction.  The Trustee  will sell  all the  Contracts to  the
highest  bidder, subject, among  other things, to: (i)  the requirement that the
highest bid  equal  or exceed  the  Minimum  Termination Amount;  and  (ii)  the
requirement  that at least one  bid be tendered by  an active participant in the
asset-backed securities  or manufactured  housing contract  market that  is  not
affiliated  with  Bank  of  America,  FSB.  If  the  foregoing  requirements are
satisfied, the successful bidder or bidders shall deposit the aggregate purchase
price  for  the  Contracts  in   the  Certificate  Account.  If  the   foregoing
requirements  are not satisfied, the purchase  shall not occur and distributions
will  continue  to  be  made  on  the  Certificates.  Any  sale  and  consequent
termination  of  the  Trust Fund  as  a  result of  a  Termination  Auction must
constitute a "qualified liquidation" of the Trust Fund under Section 860F of the
Code.
 
TERMINATION OF THE AGREEMENT
 
    The Agreement will terminate  upon the last action  required to be taken  by
the  Trustee on  the final  Distribution Date following  the earlier  of (i) the
purchase by the Servicer of all  Contracts and all property acquired in  respect
of  any  Contract remaining  in  the Trust  Fund  as described  above  under "--
Optional Termination and Termination Auction" or (ii) the final payment or other
liquidation (or any advance with respect thereto) of the last Contract remaining
in the Trust Fund or the disposition of all property
 
                                      S-64
<PAGE>
acquired upon  repossession of  any Manufactured  Home or  (iii) the  sale in  a
Termination  Auction of all Contracts and all other property acquired in respect
of any  Contract  remaining in  the  Trust Fund  as  described above  under  "--
Optional Termination and Termination Auction."
 
    Upon  presentation and surrender of  the Series 1997-1 Regular Certificates,
the Trustee shall cause to be distributed, to the extent of funds available,  to
such  Certificateholders on the  final Distribution Date  in proportion to their
respective Percentage  Interests  an  amount  equal  to  the  respective  unpaid
Certificate  Balances of the  Series 1997-1 Regular  Certificates, together with
any unpaid interest on such Certificates due on prior Distribution Dates and one
month's interest at the applicable pass-through rates on such unpaid Certificate
Balances; provided that such funds will  be distributed in the applicable  order
of  priority specified under "-- Distributions"  above. If the Agreement is then
being terminated, any amount which remains on deposit in the Certificate Account
(other than amounts retained to meet  claims) after distribution to the  holders
of  the Series 1997-1  Regular Certificates will  be distributed to  the Class R
Certificateholders.
 
COLLECTION AND OTHER SERVICING PROCEDURES
 
    The Servicer will administer, service and make collections on the Contracts,
exercising the  degree of  care  that the  Servicer  exercises with  respect  to
similar contracts serviced by the Servicer.
 
    Subject to the requirements of applicable law, the Servicer will be required
to  commence repossession and  other realization procedures  with respect to any
defaulted Contract promptly  after the  Servicer determines  that such  Contract
will  not be brought current. The Servicer  may rescind, cancel or make material
modifications of the terms  of a Contract (including  modifying the amounts  and
Due  Dates  of Scheduled  Payments)  in connection  with  a default  or imminent
default thereunder.
 
SERVICING COMPENSATION; CERTAIN OTHER MATTERS REGARDING THE SERVICER
 
    For its servicing of the Contracts, the Servicer will be entitled to receive
a monthly servicing fee  equal to the  product of one-twelfth  of 1.00% and  the
Pool Scheduled Principal Balance for the related Distribution Date (the "Monthly
Servicing  Fee"), whether or not the related Scheduled Payments on the Contracts
are received.  The Available  Distribution Amount  will be  net of  the  Monthly
Servicing Fee. See "-- Payments on the Contracts; Certificate Account" above.
 
    As part of its servicing fees, the Servicer will also be entitled to retain,
as  compensation for the  additional services provided  in connection therewith,
any fees for late payments made by Obligors, extension fees paid by Obligors for
the  extension  of  scheduled  payments   and  assumption  fees  for   permitted
assumptions of Contracts by purchasers of the related Manufactured Homes.
 
THE TRUSTEE
 
    The  First National Bank of Chicago  (the "Trustee") has its corporate trust
offices at One First National  Plaza, Chicago, Illinois 60670-0126. The  Trustee
may resign at any time, in which event the Seller will be obligated to appoint a
successor  Trustee. The Seller 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 Seller will also be obligated to appoint a
successor Trustee. Any resignation or removal of the Trustee and appointment  of
a   successor  Trustee  will  not  become  effective  until  acceptance  of  the
appointment by the successor Trustee.
 
    The Agreement  requires the  Trustee to  maintain, at  its own  expense,  an
office  or  agency  in  New  York City  or  Chicago  where  Certificates  may be
surrendered for  registration of  transfer  or exchange  and where  notices  and
demands  to or upon the Trustee and  the certificate registrar in respect of the
Certificates pursuant to the Agreement may be served.
 
    The Trustee,  or any  of its  affiliates,  in its  individual or  any  other
capacity,  may become the owner or pledgee  of Certificates with the same rights
as it would have if it were not Trustee.
 
    The Trustee  will  also  act  as paying  agent,  certificate  registrar  and
authenticating agent under the Agreement.

                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
    Upon  the issuance  of the  Offered Certificates,  Morrison &  Foerster LLP,
special counsel to BankAmerica Housing Services, will deliver its opinion  that,
assuming   (i)  the  making  of  appropriate  elections,  (ii)  compliance  with
applicable provisions of the Code, including  Sections 860A through 860G of  the
Code  (the  "REMIC Provisions"),  and  related Treasury  regulations,  and (iii)
compliance by  the  Seller,  the  Servicer  and the  Trustee  with  all  of  the
provisions  of  the related  Agreements, (a)  the Trust  Fund will  qualify, for
federal income tax purposes, as a  "real estate mortgage investment conduit"  (a
"REMIC")  within  the  meaning of  the  REMIC  Provisions, and  (b)  the Offered
Certificates, together with  the Class B-2  Certificates, evidence the  "regular
interests"  in such REMIC and (c) the Class  R Certificates is the sole class of
"residual interests" in such REMIC, respectively, each within the meaning of the
REMIC Provisions in effect on the date hereof.
 
    The following  general  discussion of  the  anticipated federal  income  tax
consequences of the purchase, ownership and disposition of Offered Certificates,
to  the extent it  relates to matters  of law or  legal conclusions with respect
thereto, represents the opinion of Morrison  & Foerster LLP, special counsel  to
BankAmerica Housing Services, subject to the qualifications set forth herein. In
addition,  Morrison  &  Foerster  LLP, special  counsel  to  BankAmerica Housing
Services, has prepared or reviewed the statements in this Prospectus  Supplement
under  the  heading "Certain  Federal Income  Tax Consequences,"  and is  of the
opinion that  such  statements  are  correct  in  all  material  respects.  Such
statements  are intended as an explanatory discussion of the possible effects of
the classification of the Trust Fund as a REMIC for federal income tax  purposes
on investors generally and of related tax matters affecting investors generally,
but  do not purport  to furnish information in  the level of  detail or with the
attention to an investor's specific tax circumstances that would be provided  by
an  investor's own tax advisor. Accordingly, each investor is advised to consult
its own tax advisors with regard to  the tax consequences to it of investing  in
the Offered Certificates.
 
    The  Offered Certificates  will be Regular  Certificates (as  defined in the
Prospectus  under   "Certain   Federal   Income  Tax   Consequences   --   REMIC
Certificates").  Generally,  the Offered  Certificates will  be treated  as debt
instruments for federal income tax purposes 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 the
accrual method of accounting, regardless of their normal tax accounting method.
 
    Certain classes of the Offered  Certificates, depending on their  respective
issue  prices, may  be issued with  original issue discount  ("OID") for federal
income tax purposes. The prepayment assumption that will be used in  determining
the  rate of accrual of OID is 170%. No representation is made as to whether the
Contracts will prepay at that rate or any other rate.
 
    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)  assets
described  in Section 7701(a)(19)(C)  of the Code and  (ii) "real estate assets"
within the meaning of Section 856(c)(5) of the Code, in each case to the  extent
described  in the  Prospectus. As 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.  The  Small  Business Job  Protection  Act of  1996  generally repealed,
effective for  taxable years  beginning  after December  31, 1995,  the  reserve
method  of accounting for  bad debts of  certain financial institutions formerly
provided under  Section  593  of  the Code.  Regular  certificates  in  a  REMIC
generally  were treated as "qualifying real property loans" for purposes of such
Section 593 to the  extent described in the  Prospectus. Entities that  formerly
used  the Section  593 method  of accounting continue  to be  subject to certain
requirements under the Code.  Accordingly, entities affected  by Section 593  of
the Code should consult their own tax advisors concerning these provisions.
 
    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,
 
                                      S-66
<PAGE>
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. Legislation  is
currently  pending  in Congress  which, if  enacted in  its present  form, would
reduce the long-term capital gain tax rate applicable to individuals and  change
the  holding period required to qualify for long-term capital gain treatment. No
assurances can be provided that such legislation will in fact be enacted.
 
    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.
 
SENIOR CERTIFICATES
 
    The Department  of  Labor  ("DOL")  has granted  to  Morgan  Stanley  &  Co.
Incorporated  an administrative exemption  (DOL Prohibited Transaction Exemption
90-24, Exemption Application No. D-8019, 55 Fed. Reg. 20548 (May 17, 1990)) (the
"Exemption")) from certain  of the  prohibited transaction rules  of ERISA.  The
Exemption  exempts from the prohibitions of Sections 406(a) and 407(a) of ERISA,
and the related excise tax provisions of Section 4975 of the Code, the purchase,
holding, and resale by Plans of pass-through certificates representing interests
in trusts that hold assets  consisting primarily of certain receivables,  loans,
and  other obligations  that meet the  general conditions  summarized below. The
receivables covered by  the Exemption include  manufactured housing  installment
sales  contracts and installment  loan agreements secured  by manufactured homes
such as the Contracts. The Seller believes that the Exemption will apply to  the
acquisition  and holding of Senior Certificates by Plans and that all conditions
of the Exemption other than those within the control of the investors have  been
or will be met.
 
                                      S-67
<PAGE>
    Among  the general conditions  which must be satisfied  for the Exemption to
apply  to  the  acquisition,  holding  and  resale  by  a  Plan  of  the  Senior
Certificates are the following:
 
    (1)  The  acquisition of  the  Senior Certificates  by  a Plan  is  on terms
(including the price for the Senior Certificates) that are at least as favorable
to the Plan as they  would be in an  arm's-length transaction with an  unrelated
party.
 
    (2)  The rights and interests evidenced  by the Senior Certificates acquired
by the Plan are not subordinated to the rights and interests evidenced by  other
Certificates of the Trust.
 
    (3)  The Senior Certificates acquired by the  Plan have received a rating at
the time of such acquisition that is in one of the three highest generic  rating
categories from either Moody's or Fitch.
 
    (4) The Trustee is not an affiliate of the Underwriters, BankAmerica Housing
Services,  any  Obligor with  respect to  Contracts included  in the  Trust Fund
constituting more than 5% of the aggregate unamortized principal balance of  the
assets  in the Trust Fund, or any  affiliate of such parties. (Such parties, and
the Trustee and its affiliates, are sometimes referred to herein collectively as
the "Restricted  Group"). As  of the  date hereof,  no Obligor  with respect  to
Contracts  included in the  Trust Fund is  an Obligor with  respect to Contracts
constituting more than 5% of the aggregate unamortized principal balance of  the
assets of the Trust Fund.
 
    (5)  The sum  of all payments  made to  and retained by  the Underwriters in
connection with the distribution of the Senior Certificates represents not  more
than  reasonable compensation for underwriting  the Senior Certificates. The sum
of all payments made to and retained by  the Seller 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. The Seller  believes 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 Senior  Certificates
between  either Seller or  the Underwriters and  a Plan when  the person who has
discretionary authority  or  renders  investment  advice  with  respect  to  the
investment  of the Plan's assets in the Senior Certificates (the "Fiduciary") is
(a) an obligor with respect to 5% or less of the fair market value of  Contracts
in the Trust Fund or (b) an affiliate of any such person, subject to the general
conditions summarized above and to the following additional requirements:
 
    (1) No member of the Restricted Group is a sponsor of the Plan.
 
    (2) In connection with the initial issuance of Senior Certificates, at least
50% in Percentage Interests of such Class of Certificates is acquired by persons
independent  of the Restricted Group and at  least 50% of the aggregate interest
in the Trust Fund is acquired by persons independent of the Restricted Group.
 
    (3) The Plan's investment in the Senior Certificates does not exceed 25%  in
Percentage  Interests of any such Class  of Certificates outstanding at the time
of acquisition.
 
                                      S-68
<PAGE>
    (4) Immediately after the  acquisition of the  Senior 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 Senior Certificates by a Plan in the secondary market if certain
conditions are met and the continued holding of Senior Certificates acquired  in
initial or secondary markets.
 
    Before  purchasing a Senior  Certificate, a fiduciary of  a Plan should make
its own determination as to the availability of the exemptive relief provided in
the  Exemption  or  the  availability   of  any  other  prohibited   transaction
exemptions,  and whether the conditions of any such exemption will be applicable
to the Certificate. Any  fiduciary of a Plan  considering whether to purchase  a
Senior  Certificate should also carefully review with its own legal advisors the
applicability of the  fiduciary duty  and prohibited  transaction provisions  of
ERISA  and  the  Code to  such  investment.  See "ERISA  Considerations"  in the
Prospectus.

                     CERTAIN LEGAL ASPECTS OF THE CONTRACTS
 
LAND HOME AND LAND-IN-LIEU CONTRACTS
    GENERAL.  Approximately 7.32%  (by principal balance)  of the Contracts  are
Land  Home Contracts or Land-in-Lieu Contracts.  The Land Home Contracts and the
Land-in-Lieu Contracts will  be secured by  either first mortgages  or deeds  of
trust  on the real estate  on which the manufactured  home is located, depending
upon the prevailing practice  in the state in  which the underlying property  is
located.  A mortgage  creates a  lien upon  the real  property described  in the
mortgage. There  are  two parties  to  a mortgage:  the  mortgagor, who  is  the
borrower,  and  the mortgagee,  who  is the  lender.  In a  mortgage  state, the
mortgagor delivers to the mortgagee a note  or bond evidencing the loan and  the
mortgage. Although a deed of trust is similar to a mortgage, a deed of trust has
three  parties: the borrower, a lender as beneficiary, and a third-party grantee
called  the  trustee.  Under   a  deed  of  trust,   the  borrower  grants   the
 
                                      S-69
<PAGE>
property,  irrevocably until the debt is paid,  in trust, generally with a power
of sale, to the trustee to secure  payment of the loan. The trustee's  authority
under  a  deed of  trust  and the  mortgagee's  authority under  a  mortgage are
governed by the express provisions of the deed of trust or mortgage,  applicable
law,  and, in some cases,  with respect to the deed  of trust, the directions of
the beneficiary.
 
    FORECLOSURE.   Foreclosure  of  a  mortgage  is  generally  accomplished  by
judicial  action. Generally,  the action  is initiated  by the  service of legal
pleadings upon all parties  having an interest of  record in the real  property.
Delays   in  completion  of   the  foreclosure  occasionally   may  result  from
difficulties in  locating necessary  parties  defendants. When  the  mortgagee's
right  to foreclosure is  contested, the legal  proceedings necessary to resolve
the issue  can  be time-consuming  and  expensive.  After the  completion  of  a
judicial  foreclosure proceeding, the court may  issue a judgment of foreclosure
and appoint a receiver or other officer to conduct the sale of the property.  In
some  states, mortgages may  also be foreclosed by  advertisement, pursuant to a
power  of  sale  provided  in  the  mortgage.  Foreclosure  of  a  mortgage   by
advertisement  is  essentially similar  to  foreclosure of  a  deed of  trust by
non-judicial power of sale.
 
    Foreclosure of a deed of trust  is generally accomplished by a  non-judicial
trustee's  sale under a specific provision in  the deed of trust that authorizes
the trustee to sell property to a  third party upon any default by the  borrower
under  the  terms  of  the  note  or deed  of  trust.  In  certain  states, such
foreclosure also may be accomplished by  judicial action in the manner  provided
for foreclosure of mortgages. In some states the trustee must record a notice of
default  and  send a  copy to  the borrower-trustor  and to  any person  who has
recorded a request for a copy of a notice of default and the notice of sale.  In
addition, the trustee must provide notice in some states to any other individual
having  an  interest  of  record  in the  real  property,  including  any junior
lienholders. If the deed of trust  is not reinstated within any applicable  cure
period,  a notice of sale must be posted  in a public place and, in most states,
published for a specified period of time in one or more newspapers. In addition,
some state laws  require that  a copy of  the notice  of sale be  posted on  the
property and sent to all parties having an interest of record in the property.
 
    In  some states, the borrower-trustor has the right to reinstate the loan at
any time following default until shortly before the trustee's sale. In  general,
the  borrower,  or any  other person  having  a junior  encumbrance on  the real
estate, may,  during a  reinstatement period,  cure the  default by  paying  the
entire  amount in arrears plus the costs  and expenses incurred in enforcing the
obligation. Certain state laws  control the amount  of foreclosure expenses  and
costs, including attorneys' fees, that may be recovered by a lender.
 
    In  the case of foreclosure under either a  mortgage or a deed of trust, the
sale by the receiver or other designated officer, or by the trustee, is a public
sale. However, because  of the difficulty  a potential buyer  at the sale  would
have in determining the exact status of title and because the physical condition
of  the property may have deteriorated during the foreclosure proceedings, it is
not common for a third party to  purchase the property at the foreclosure  sale.
Rather, the lender generally purchases the property from the trustee or receiver
for  an amount  equal to the  unpaid principal  amount of the  note, accrued and
unpaid interest  and the  expenses of  foreclosure. Thereafter,  subject to  the
right  of  the  borrower in  some  states  to remain  in  possession  during the
redemption period, the lender  will assume the  burdens of ownership,  including
obtaining  hazard insurance and  making such repairs  at its own  expense as are
necessary to render  the property suitable  for sale. The  lender commonly  will
obtain  the services of a real estate broker  and pay the broker a commission in
connection with the sale of the property. Depending upon market conditions,  the
ultimate  proceeds  of the  sale  of the  property  may not  equal  the lender's
investment in the property.
 
    RIGHTS OF REDEMPTION.   In some  states, after  sale pursuant to  a deed  of
trust  or foreclosure of a mortgage,  the borrower and certain foreclosed junior
lienors are given a statutory  period in which to  redeem the property from  the
foreclosure sale. In certain other states, this right of redemption applies only
to  sale following judicial foreclosure, and not sale pursuant to a non-judicial
power of  sale. In  most states  where  the right  of redemption  is  available,
statutory  redemption may occur upon payment  of the foreclosure purchase price,
accrued  interest  and  taxes.  In  some  states  the  right  to  redeem  is  an
 
                                      S-70
<PAGE>
equitable  right. The effect of a right of redemption is to diminish the ability
of the  lender to  sell the  foreclosed property.  The exercise  of a  right  of
redemption  would defeat the title of any purchaser at a foreclosure sale, or of
any purchaser from the lender subsequent to judicial foreclosure or sale under a
deed of trust. Consequently, the practical effect of the redemption right is  to
force the lender to maintain the property and pay the expense of ownership until
the expiration of the redemption period.
 
    ANTI-DEFICIENCY  LEGISLATION  AND  OTHER LIMITATIONS  ON  LENDERS.   Certain
states have  imposed  statutory  restrictions  that  limit  the  remedies  of  a
beneficiary  under a deed of trust or a mortgagee under a mortgage relating to a
single family  residence.  In some  states,  statutes  limit the  right  of  the
beneficiary  or mortgagee to  obtain a deficiency  judgment against the borrower
following foreclosure or sale under a deed of trust. A deficiency judgment is  a
personal  judgment against  the borrower equal  in most cases  to the difference
between the  amount due  to the  lender and  the net  amount realized  upon  the
foreclosure sale.
 
    Some  state statutes may require the beneficiary or mortgagee to exhaust the
security afforded under a deed of trust or mortgage by foreclosure in an attempt
to satisfy the full debt before bringing a personal action against the borrower.
In certain other states, the lender has the option of bringing a personal action
against the  borrower  on  the  debt without  first  exhausting  such  security;
however,  in  some  of these  states,  the  lender, following  judgment  on such
personal action, may be  deemed to have  elected a remedy  and may be  precluded
from  exercising  remedies  with  respect  to  the  security.  Consequently, the
practical effect of the election  requirement, when applicable, is that  lenders
will  usually proceed first against the security rather than bringing a personal
action against the borrower.
 
    Other statutory provisions  may limit  any deficiency  judgment against  the
former  borrower following a  foreclosure sale to the  excess of the outstanding
debt over the fair market  value of the property at  the time of such sale.  The
purpose  of  these statutes  is to  prevent  a beneficiary  or a  mortgagee from
obtaining a large deficiency judgment against the former borrower as a result of
low or  no bids  at the  foreclosure sale.  In some  states, exceptions  to  the
anti-deficiency  statutes are provided for in  certain instances where the value
of the lender's security has been impaired by acts or omissions of the borrower,
for example, in the event of waste of the property.
 
    In addition  to  anti-deficiency  and related  legislation,  numerous  other
federal  and state statutory provisions,  including the federal bankruptcy laws,
the federal  Soldiers' and  Sailors' Civil  Relief Act  of 1940  and state  laws
affording  relief to  debtors, may  interfere with  or affect  the ability  of a
secured mortgage lender to realize upon its security. For example, with  respect
to a Land Home Contract, in a Chapter 13 proceeding under the federal Bankruptcy
Code,  when  a court  determines  that the  value  of a  home  is less  than the
principal balance of the loan, the  court may prevent a lender from  foreclosing
on  the home, and, as part of the  rehabilitation plan, reduce the amount of the
secured indebtedness to the value  of the home as it  exists at the time of  the
proceeding,  leaving  the  lender  as  a  general  unsecured  creditor  for  the
difference between  that value  and the  amount of  outstanding indebtedness.  A
bankruptcy  court  may grant  the debtor  a  reasonable time  to cure  a payment
default, and  in  the case  of  a mortgage  loan  not secured  by  the  debtor's
principal  residence,  also  may  reduce the  monthly  payments  due  under such
mortgage loan, change the rate of interest and alter the mortgage loan repayment
schedule. Certain court decisions have applied such relief to claims secured  by
the debtor's principal residence.
 
    The  Code  provides priority  to  certain tax  liens  over the  lien  of the
mortgage or deed of trust. The laws  of some states provide priority to  certain
tax  liens over the  lien mortgage or  deed of trust.  Numerous federal and some
state consumer  protection laws  impose substantive  requirements upon  mortgage
lenders  in connection  with the origination,  servicing and  the enforcement of
mortgage loans. These laws include the federal Truth in Lending Act, Real Estate
Settlement Procedures Act,  Equal Credit Opportunity,  Fair Credit Billing  Act,
Fair  Credit Reporting Act, and related  statutes and regulations. These federal
laws and  state laws  impose  specific statutory  liabilities upon  lenders  who
originate  or service mortgage loans and who  fail to comply with the provisions
of the law. In some cases, this liability may affect assignees of the Contracts.
 
                                      S-71
<PAGE>
                                    RATINGS
 
    It is  a condition  to the  issuance  of the  Certificates that  the  Senior
Certificates  be rated  "Aaa" by Moody's  and "AAA"  by Fitch, that  the Class M
Certificates be rated at least "Aa3" by Moody's and "AA-" by Fitch and that  the
Class B-1 Certificates be rated at least "Baa2" by Moody's and "BBB" by Fitch. A
security  rating is not a recommendation to buy, sell or hold securities and may
be subject to revision or withdrawal at any time by the assigning rating agency.
The  security  rating   of  the   Offered  Certificates   should  be   evaluated
independently of similar security ratings assigned to other kinds of securities.
 
    The  ratings  assigned by  Moody's  and Fitch  to  pass-through certificates
address the likelihood of the receipt by the related certificateholders of their
allocable share of principal and interest on the underlying assets. Moody's  and
Fitch  ratings  take  into  consideration  the  credit  quality  of  the related
underlying assets, any credit support arrangements, structural and legal aspects
associated with such certificates, and the extent to which the payment stream on
such  underlying  assets  is  adequate   to  make  payments  required  by   such
certificates.  Moody's and Fitch  ratings on such  certificates do not, however,
constitute a  statement regarding  frequency of  prepayments on  the  underlying
assets  or as to whether yield may be adversely affected as a result thereof. An
explanation of the  significance of such  ratings may be  obtained from  Moody's
Investors  Service, Inc., 99 Church Street, New York, New York 10004, telephone:
(212) 553-0300, and Fitch Investors Service,  L.P., One State Street Plaza,  New
York, New York 10004, telephone (212) 908-0500, respectively.
 
    The  Seller has not  requested a rating  on the Offered  Certificates by any
rating agency other than Moody's and  Fitch. However, there can be no  assurance
as  to whether  any other  rating agency  will rate  any or  all of  the Offered
Certificates, or  if  it did,  what  rating would  be  assigned to  the  Offered
Certificates  by any  such other rating  agency. A rating  on any or  all of the
Offered Certificates by certain other rating  agencies, if assigned at all,  may
be lower than the rating assigned to such Certificates by Moody's and Fitch.
 
                                LEGAL INVESTMENT
 
    The  Senior and Class M Certificates at the time of issuance will qualify as
"mortgage related securities"  under the Secondary  Mortgage Market  Enhancement
Act  of  1984,  as  amended  ("SMMEA")  and,  as  such,  will  constitute  legal
investments for certain types of investors to the extent provided in SMMEA. Such
institutions should consult their own legal advisors in determining whether  and
to  what extent  the Senior Certificates  constitute legal  investments for such
investors.
 
    Because the Class  B-1 Certificates will  not, at the  time of issuance,  be
rated  in one  of the two  highest rating  categories of Moody's  and Fitch, the
Class B-1 Certificates  will not  constitute "mortgage  related securities"  for
purposes of SMMEA. Accordingly, many institutions with legal authority to invest
in more highly rated securities based on first mortgage loans may not be legally
authorized to invest in the Class B-1 Certificates. No representation is made as
to  any regulatory requirements or  considerations (including without limitation
regulatory capital  or permissible  investment requirements)  applicable to  the
purchase  of the Class B-1 Certificates  by banks, savings and loan associations
or other  financial institutions.  Such institutions  should consult  their  own
legal   advisors  in  determining  whether  and   to  what  extent  the  Offered
Certificates  constitute  legal  investments  for  such  investors.  See  "Legal
Investment" in the Prospectus.

    In the Underwriting Agreement, the Underwriters have agreed, subject to  the
terms  and  conditions  set  forth  therein,  to  purchase  all  of  the Offered
Certificates 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.
 
    The Seller has been advised by the Underwriters that they propose  initially
to  offer the Offered Certificates to the public at the prices set forth herein,
and to certain dealers at such prices less the initial concession not in  excess
of  0.0735%  of the  Class A-1  Certificate  Balance, 0.0900%  of the  Class A-2
Certificate Balance, 0.1050% of  the Class A-3  Certificate Balance, 0.1200%  of
the Class A-4 Certificate Balance, 0.1500% of the Class A-5 Certificate Balance,
0.1800%  of  the  Class  A-6  Certificate  Balance,  0.2100%  of  the  Class A-7
Certificate Balance, 0.2400% of  the Class A-8  Certificate Balance, 0.2550%  of
the  Class A-9 Certificate Balance, 0.2700%  of the Class M Certificate Balance,
0.3000% of  the  Class  B-1  Certificate Balance.  The  Underwriters  may  allow
dealers,  and such dealers may allow, a  concession not in excess of 0.03675% of
the Class A-1 Certificate Balance, 0.0450% of the Class A-2 Certificate Balance,
0.0525% of  the  Class  A-3  Certificate  Balance,  0.0600%  of  the  Class  A-4
Certificate  Balance, 0.0750% of  the Class A-5  Certificate Balance, 0.0900% of
the Class A-6 Certificate Balance, 0.1050% of the Class A-7 Certificate Balance,
0.1200% of  the  Class  A-8  Certificate  Balance,  0.1275%  of  the  Class  A-9
Certificate  Balance, 0.1350% of the Class M Certificate Balance, and 0.1500% of
the Class B-1  Certificate Balance.  After the  initial public  offering of  the
Offered  Certificates, the  public offering prices  and such  concessions may be
changed.
 
    The Underwriting  Agreement  provides that  the  Seller 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.
 
    The Underwriters will reimburse certain expenses of the Seller.
 
    In  connection with the  sale of the  Offered Certificates, the Underwriters
and other persons  participating in  the sale  may engage  in transactions  that
stabilize,  maintain or otherwise affect the  price of the Offered Certificates.
Specifically, the  Underwriters  may over-allot  in  connection with  the  sale,
creating  a short position in the Offered Certificates for their own account. To
cover over-allotments or to stabilize the price of the Offered Certificates, the
Underwriters may bid for, and purchase, Offered Certificates in the open market.
Finally, the Underwriters  may bid  for, and purchase,  Offered Certificates  in
market  making  transactions. These  activities  may stabilize  or  maintain the
market price of the Offered Certificates above market levels that may  otherwise

                     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  18 sold pools  for which prepayment  information is  available
covering  a period of  at least 16  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 March 1997 (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 March 1, 1997. 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.

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
 
    There are incorporated herein by  reference all reports and other  documents

    Unless and until Definitive Certificates (as defined herein) with respect to
a  Trust Fund  are issued, monthly  and annual reports,  which contain unaudited

sent  on behalf  of the Trust  Fund to  Cede & Co.  ("Cede"), as  nominee of The
Depository Trust  Company  ("DTC") and  registered  holder of  the  Certificates
offered  hereby, pursuant to the Agreement (as defined herein). See "Description

not  intend to send, any  of their financial reports  to registered holders (the
"Certificateholders") of  the  Certificates offered  hereby  or to  owners  (the

such  reports  with  the Commission.  The  Trustee would,  however,  continue to
provide periodic reports to Certificateholders as and to the extent described in

                                  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

                                  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, the failure of a third
                                  party credit support provider, if any, to make a  required
                                  payment,  or a  combination of  the foregoing  events. See

                                  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

                                  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, if  any, by  which the  interest
                                  collected   on  nondefaulted  Contracts  during  the  same
                                  Collection Period exceeds the interest distribution due to

                                  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

                                  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,

                                  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

                                  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 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

                                  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

                                  "Pass-Through Rate") specified  in the related  Prospectus
                                  Supplement.   The  Pass-Through  Rate   may  be  fixed  or
                                  variable, and,  if  specified in  the  related  Prospectus
                                  Supplement, may shift from a variable rate to a fixed rate
                                  under   the  conditions   specified  in   such  Prospectus
                                  Supplement.  See  "Description  of  the  Certificates   --
                                  Distributions  on  Certificates  --  B.  Distributions  of
                                  Interest" herein for a general description of the types of
                                  variable Pass-Through Rates that might be applicable to  a
                                  Class of Certificates. Alternatively, such interest may be
                                  equal   to  all  or  a  portion  (which  portion  will  be
                                  determined  as   described  in   the  related   Prospectus
                                  Supplement)  of the interest due  on the related Contracts
                                  during one or more  Collection Periods occurring prior  to
                                  such  Distribution Date.  Classes of  Certificates that do
                                  not entitle the holders  thereof to receive  distributions
                                  of  principal  may  nevertheless entitle  such  holders to
                                  receive 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
                                  applicable Prospectus Supplement.
C. Residual Interests...........  If specified in the related Prospectus Supplement, a Class
                                  of Certificates  in any  Series  may evidence  a  residual
                                  interest   in  the  related   Trust  Fund  (the  "Residual
                                  Interest"). Any such Class  will not have been  registered
                                  under  the Securities Act and will  not be offered or sold
                                  pursuant to  this  Prospectus. 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
                                  Interest  may entitle the holders thereof to distributions
                                  at various times throughout the life of the related  Trust
                                  Fund  or only upon  termination of the  Trust Fund, all as
                                  more fully set forth in the related Prospectus Supplement.
                                  If an election is made to treat the related Trust Fund  as
                                  a  REMIC, the holders of a Residual Interest in such Trust
                                  Fund will  be  subject  to federal  income  taxation  with
                                  respect to their

                                  more Classes within a Series, will be issuable in the form
                                  of  one  or  more  global  certificates  (each,  a "Global

                                  to Cede and not to the Certificate Owners, as described in

                                  to make advances of  delinquent scheduled payments on  the

                                  related Prospectus Supplement.
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 within ninety
                                  days following the Distribution Date as of which the  Pool
                                  Principal  Balance for a Contract Pool is less than 10% of

                                  made.
ERISA Considerations............  A fiduciary of  any employee benefit  plan subject to  the
                                  Employee  Retirement  Income  Security  Act  of  1974,  as
                                  amended ("ERISA"),  or Section  4975  of the  Code  should
                                  carefully  review with its own  legal advisors whether the
                                  purchase or holding of Certificates  could give rise to  a
                                  transaction  that is prohibited or otherwise impermissible
                                  under ERISA or the Code. See "ERISA Considerations" herein
                                  and in the related Prospectus Supplement. If specified  in
                                  the  related  Prospectus Supplement,  certain Certificates
                                  sold hereunder will not be transferable to certain benefit
                                  plan investors except  under the conditions  set forth  in
                                  such Prospectus Supplement.
Legal Investment................  Unless  otherwise indicated  in the  applicable Prospectus
                                  Supplement, any Certificates offered hereby that are rated

                                  one  of its  two highest rating  categories will generally
                                  constitute  "mortgage   related  securities"   under   the
                                  Secondary  Mortgage  Market  Enhancement Act  of  1984, as
                                  amended  ("SMMEA")   and,  as   such,  would   be   "legal
                                  investments"  for certain types of institutional investors
                                  to the extent provided in  SMMEA. Certain state laws  have
                                  overridden  SMMEA and,  therefore, institutional investors
                                  should review with their  own legal advisors whether  such
                                  Certificates  would  constitute  a  legal  investment.  In
                                  addition, some Classes of Certificates offered hereby  may
                                  not  be rated in one of  the two highest rating categories
                                  and  thus   would   not   constitute   "mortgage   related
                                  securities."  See  "Legal  Investment" herein  and  in the
                                  related Prospectus Supplement.
Rating..........................  It is  a  condition  to  the issuance  of  each  Class  of
                                  Certificates  sold under this Prospectus  that it be rated
                                  at the  time  of  issuance  by  at  least  one  nationally
                                  recognized  statistical rating organization  in one of its
                                  four highest rating categories. A security rating is not a
                                  recommendation to buy, sell or hold securities and may  be
                                  subject  to  revision or  withdrawal  at any  time  by the
                                  assigning rating agency. The security rating of any  Class
                                  of  Certificates  should  be  evaluated  independently  of
                                  similar  security  ratings  assigned  to  other  kinds  of
                                  securities,  including Certificates in  the same Series or
                                  Certificates of other Series sold under this 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.
                                  See   "Rating"  herein  and   in  the  related  Prospectus
                                  Supplement.

<PAGE>
                                  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
 
                                       13
<PAGE>
CONSTITUTE THE  ONLY SOURCE  OF FUNDS  FOR PAYMENT  ON THE  CERTIFICATES OF  THE
RELATED  SERIES. THE CERTIFICATES WILL NOT REPRESENT INTERESTS IN OR OBLIGATIONS
OF BANK  OF AMERICA,  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)
 
                                       14
<PAGE>
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, 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
 
                                       15
<PAGE>
may be  influenced  by a  variety  of  economic, geographic,  social  and  other
factors,  including repossessions, aging, seasonality  and interest rates. Other
factors affecting prepayment on such Contracts include changes in housing needs,
job transfers and unemployment. In addition,  in the event a partial  prepayment
is  made on  a Contract,  or a  Contract is  prepaid in  full, interest  on such
Contract to the extent of such prepayment will cease to accrue as of the date of
prepayment. If  with respect  to any  Trust Fund  such prepayments  and  related
interest  shortfalls  were sufficiently  high  during a  Collection  Period, the
Available  Distribution  Amount  (as   defined  in  the  applicable   Prospectus
Supplement)  for the related Distribution Date could  be less than the amount of
principal  and   interest   that  would   be   distributable  to   the   related
Certificateholders  in the absence of such shortfalls. See "Prepayment and Yield
Considerations" herein and in the related Prospectus Supplement.
 
    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.
 
    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
 
                                       17
<PAGE>
Scheduled  Payments;  otherwise  such  payment would  be  applied  as  a partial
principal prepayment. There is no limit to the number of Scheduled Payments that
may be paid ahead  in this manner. The  effect of paid-ahead Scheduled  Payments
will be different for actuarial Contracts than for simple interest Contracts, as
further described below.
 
    The  Scheduled Payments  for each actuarial  Contract (whether  a fixed rate
Contract or a Step-Up Rate Contract)  will fully amortize the principal  balance
of  the Contract over its term. The  portion of each Scheduled Payment allocable
to principal is equal to the total amount thereof less the portion allocable  to
interest.  The portion of each Scheduled Payment  due in a particular month that
is allocable to interest is a  precomputed amount equal to one month's  interest
on  the principal balance of the Contract, which principal balance is determined
by reducing  the initial  principal  balance by  the  principal portion  of  all
Scheduled  Payments that were due in prior months (whether or not such Scheduled
Payments were timely made)  and all prior  partial principal prepayments.  Thus,
each  Scheduled  Payment  will  be  applied  to  interest  and  to  principal in
accordance with a  precomputed allocation, whether  such Scheduled Payments  are
received  in  advance of  or  subsequent to  their  Due Dates.  Unless otherwise
specified in the applicable  Prospectus Supplement, all  payments received in  a
Collection  Period on an  actuarial Contract in excess  of the related Obligor's
Scheduled Payment (other than payments  not allocated to principal and  interest
(such  as  late payment  charges)  or payments  sufficient  to pay  in  full the
outstanding principal balance  of and all  accrued and unpaid  interest on  such
Contract)  are applied  as a  partial prepayment  of principal  on the Contract,
unless (i) the related Obligor notifies or confirms with the Servicer that  such
payments  are to be applied to future Scheduled Payments in the order of the Due
Dates  of  such  payments  or  (ii)  the  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
 
                                       18
<PAGE>
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") 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.

BANKAMERICA HOUSING SERVICES, AN UNINCORPORATED DIVISION OF BANK OF AMERICA, FSB
 
    BankAmerica  Housing  Services  is  an unincorporated  division  of  Bank of
America, FSB ("BAFSB");  BankAmerica Housing  Services is not  a separate  legal
entity  from BAFSB,  and all  references in  this Prospectus  and any Prospectus
Supplement to BankAmerica Housing  Services (unless otherwise specified  herein)
are  intended to reflect its status as a division of, and not a corporate entity
separate from,  BAFSB.  In  the  fourth quarter  of  1992,  BankAmerica  Housing
Services  began  purchasing  and  originating  manufactured  housing installment
contracts through the regional  offices in the United  States of its  affiliate,
Security  Pacific Housing  Services, Inc. ("SPHSI").  Prior to  that time, SPHSI
conducted  the  business  of  purchasing,  originating,  servicing  and  selling
manufactured  housing contracts. SPHSI discontinued the conduct of that business
in July 1993, transferring to  BankAmerica Housing Services the regional  office
structure,  systems  and employees  relating  to that  business.  The applicable
Prospectus Supplement will contain a description of SPHSI's loan origination and
underwriting practices for any Contract  contained in the related Contract  Pool
that was originated or purchased by SPHSI on an individual basis in the ordinary
course  of  its  business.  BankAmerica Housing  Services'  principal  office is
located at 10089 Willow Creek Road, San Diego, California 92131-2447  (telephone
619-549-4700).
 
BANK OF AMERICA, FSB
 
    BAFSB  is a federal savings bank  and wholly owned subsidiary of BankAmerica
Corporation. As of December  31, 1995, BAFSB  and its consolidated  subsidiaries
accounted  for approximately 3% of the  consolidated total assets of BankAmerica
Corporation  and  constituted  BankAmerica  Corporation's  sixth  largest   bank
subsidiary. As of December 31, 1995, and based on the Thrift Financial Report of
BAFSB  at such date, BAFSB and  its consolidated subsidiaries had total deposits

million.   BAFSB's  headquarters  are  located  in  Portland,  Oregon,  and  its
administrative offices  are located  at 555  California Street,  San  Francisco,
California 94104 (telephone 415-622-2220).
 
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
total  assets  of  the  BankAmerica  Corporation  and  constituted   BankAmerica
Corporation's largest bank subsidiary. As of December 31, 1995, and based on the
Consolidated  Report  of Condition  of Bank  of  America at  such date,  Bank of
America and its consolidated subsidiaries  had total deposits of $119.2  billion
(including  deposits  from  BankAmerica Corporation  and  other  subsidiaries of
BankAmerica Corporation of  $2.0 billion),  total assets of  $163.4 billion  and

    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
 
                                       20
<PAGE>
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.
 
    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
 
                                       21
<PAGE>
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 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.
 
                                       22
<PAGE>
    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, 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
 
                                       23
<PAGE>
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. The
following table  shows  the  size  of  the  portfolio  of  manufactured  housing
contracts  serviced (including contracts  already in repossession)  by SPHSI and
now BankAmerica  Housing  Services  through the  manufactured  housing  regional
office system as of the dates indicated:

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 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
 
                                       27
<PAGE>
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 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
 
                                       28
<PAGE>
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.
 
    The  yield  to  holders of  any  Class  of Certificates  may  be  below that
otherwise produced by the  applicable Pass-Through Rate  because, while, in  the
absence  of  losses  or  delinquencies,  one  month's  interest  on  the related
Contracts will be collected during each  Collection Period, the portion of  such
interest  to which  the holders  of such Certificates  are entitled  will not be
distributed until the first Distribution Date after such Collection Period.
 
    If a  Certificate is  subject  to mandatory  repurchase,  the yield  to  the
Repurchase  Date  will  be  affected  by,  among  other  things,  the applicable
repurchase price, the ability of any Liquidity Facility Provider (as hereinafter
defined) to distribute the repurchase price and  the date, if any, on which  the
Repurchase  Date  occurs. If,  in connection  with  a mandatory  repurchase, the
repurchase price  for a  Certificate is  equal to  its Percentage  Interest  (as
hereinafter   defined)  of  the  then   current  Certificate  Balance,  and  the
Certificate is  purchased  at  a  discount, and  the  purchaser  calculates  its
anticipated  yield to  the Repurchase Date  based on an  assumed Repurchase Date
that is earlier than  the actual Repurchase Date,  then such purchaser's  actual
yield to maturity will be lower than it would have been if a repurchase occurred
on the assumed date.
 
    The  payment  features of  the Contracts  comprising  any Contract  Pool (as
described above under  "The Contract  Pools") may,  under certain  extraordinary
circumstances,  cause the amounts collected thereon during particular Collection
Periods to be insufficient to fund  all distributions of principal and  interest
to the holders of some or all of the Certificates of the related Series, even in
the  absence of  losses or  delinquencies. Such  circumstances could  occur if a
sufficiently large number of partial or full prepayments, as a percentage of the
then outstanding  Pool  Principal Balance  of  the related  Contract  Pool,  are
received on Contracts in a particular Collection Period, if such prepayments are
made  in advance of such Contracts'  respective Due Dates during such Collection
Period. In such  case, a  non-default collection shortfall  could occur  because
interest  that actually  accrues on  such Contracts  is less  than interest that
would have accrued if  the payments were paid  on the Contracts' respective  Due
Dates.  A non-default collection  shortfall could adversely  affect the yield to
holders of  any Class  of Certificates  to the  extent such  shortfalls are  not
covered by credit enhancement or advances.

                        DESCRIPTION OF THE CERTIFICATES
 
    Each Series of Certificates will be issued pursuant to a separate Agreement.
The  following summaries  describe certain provisions  expected to  be common to
each Agreement and the related Certificates,  but do not purport to be  complete
and  are subject to,  and are qualified  in their entirety  by reference to, the
provisions of the related Agreement and the description set forth in the related
Prospectus Supplement. Section references contained herein refer to sections  of
the  form of Agreement  filed as an  exhibit to the  Registration Statement. The
Prospectus Supplement  for  each  Series will  describe  the  specific  material
provisions  of the Agreement relating to such Series. Capitalized terms used and
not otherwise defined  herein shall have  the meanings assigned  to them in  the
form of Agreement filed as an exhibit to the Registration Statement.
 
GENERAL
 
    The  Certificates may be issued in one  or more Classes. If the Certificates
of a Series are issued in more than  one Class, the Certificates of all or  less
than  all of such Classes may be sold pursuant to this Prospectus, and there may
be separate Prospectus Supplements  relating to one or  more of such Classes  so
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.)
 
    The  Certificates of each Series will  evidence an interest, as specified in
the related Prospectus Supplement, in a Trust Fund. Each Trust Fund will include
(i) a  Contract  Pool, including  certain  rights  to receive  payments  on  the
Contracts  comprising such Contract Pool on and after the Cut-off Date, (ii) the
amounts held from time to time in the "Certificate Account" (as described in the
applicable Prospectus  Supplement under  "-- Payment  on Contracts;  Certificate
Account")  maintained  by  the  Trustee pursuant  to  the  Agreement,  (iii) any
property which initially secured a Contract and which is acquired in the process
of realizing  thereon, (iv)  the  obligations of  Bank of  America,  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
 
                                       30
<PAGE>
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.
 
    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
 
                                       31
<PAGE>
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 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
 
                                       32
<PAGE>
more forms  of  credit  support or  from  any  other source  specified  in  such
Prospectus Supplement. The Certificates of a Class having an initial Certificate
Balance  may entitle the  holders thereof to  distributions of Regular Principal
only,  to  distributions   of  Regular  Principal   and  to  Special   Principal
Distributions  or  to  Special  Principal  Distributions  only.  However, unless
otherwise stated in  the related  Prospectus Supplement, the  Certificates of  a
Class  will not entitle the holders thereof to aggregate principal distributions
in excess of the initial Certificate Balance for such Class.
 
    B. DISTRIBUTIONS  OF INTEREST.   The  distribution formula  for a  Class  of
Certificates  having  an initial  Certificate Balance  may,  but need  not, also
specify a  method  of computing  the  interest, if  any,  to be  distributed  on
specified  Distribution Dates  (which may  include all or  less than  all of the
Distribution Dates)  to the  holders of  the Certificates  of such  Class.  Such
interest  may be equal, subject  to such adjustments as  may be described in the
related Prospectus Supplement, to  a specified number of  days' interest on  the
applicable Certificate Balance (before giving effect to any reduction thereof on
such  Distribution  Date),  calculated  at  a  rate  (the  "Pass-Through  Rate")
specified in the  related Prospectus  Supplement. The Pass-Through  Rate may  be
fixed  or variable, and, if specified  in the related Prospectus Supplement, may
shift from a variable  rate to a  fixed rate under  the conditions specified  in
such  Prospectus Supplement. Variable  Pass-Through Rates may  vary from time to
time based upon changes in  an index or other  measure of certain market  rates,
all  as more fully described in the related Prospectus Supplement. In that case,
the time period between  Pass-Through Rate adjustments  (each, a "Rate  Period")
and  the specific basis on which the Pass-Through Rate for each Rate Period will
be determined  (including  the  particular market  rates  and  measures  thereof
relevant  for determining the Pass-Through Rate for each Rate Period) may remain
constant or may  change from time  to time at  the election of  the Servicer  or
otherwise,  all  as specified  in  the related  Prospectus  Supplement. Variable
Pass-Through Rates may also vary from time  to time, in the manner specified  in
the related Prospectus Supplement, based upon changes in the weighted average of
the Contract Rates of the Contracts in the related Contract Pool or on any other
basis.  To the extent  set forth in the  related Prospectus Supplement, variable
Pass-Through Rates may also have floor  rates and/or ceiling rates which may  be
fixed  or subject to adjustment  as set forth in  such Prospectus Supplement. In
addition, a variable Pass-Through Rate may be converted to a fixed  Pass-Through
Rate  at  the  election  of  the  Sellers  or  upon  the  occurrence  of certain
conditions. In that event, the related Prospectus Supplement will set forth  the
conditions  under which  the variable  Pass-Through Rate  may be  converted to a
fixed Pass-Through Rate.
 
    Rather than  entitling  the  holders thereof  to  receive  distributions  of
interest  based  upon  a Pass-Through  Rate,  the distribution  formula  for the
Certificates of a  Class may  entitle the  holders thereof  to distributions  of
interest on specified Distribution Dates (which may include all or less than all
of  the Distribution Dates) equal, in the case of any such Distribution Date, to
all or a portion (which portion will  be determined as described in the  related
Prospectus  Supplement) of the interest payable  on the related 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
 
                                       33
<PAGE>
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
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
 
                                       34
<PAGE>
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 will  equal the greater of  (a) the sum of  (x)
100%  of the Pool Scheduled  Principal Balance of each  Contract (other than any
Contract as to which the related Manufactured Home has been acquired and not yet
disposed of  and whose  fair market  value is  included pursuant  to clause  (y)
below)  as of the final Distribution Date, and (y) the fair market value of such
acquired property (as  determined by the  Servicer) and (b)  the aggregate  fair
market  value (as determined by the Servicer) of all of the assets of such Trust
Fund, plus, in  the case of  both clause (a)  and (b), an  amount sufficient  to
reimburse  Certificateholders for  each outstanding  Class for  any shortfall in
interest due thereto in respect of prior Distribution Dates. Notwithstanding the
foregoing, the Servicer's option shall not  be exercisable if there will not  be
distributed to the Certificateholders for each outstanding Class an amount equal
to  the aggregate Certificate  Balance for each  outstanding Class together with
any shortfall in  interest due to  such Certificateholders in  respect of  prior
Distribution Dates and one month's interest on the aggregate Certificate Balance
for each outstanding Class at the respective Pass-Through Rates for such Classes
(the  "Minimum  Termination Amount").  See "Description  of the  Certificates --
Optional Termination" in the related Prospectus Supplement. (Section 10.01.)
 
    B. MANDATORY REPURCHASE.  Some or all of the Certificates of a Class may  be
subject  to repurchase  by or  on behalf  of the  Sellers at  the option  of the
holders thereof and/or at the option of the Sellers, but only to the extent,  at
the  prices, on  the dates  and under  the conditions  specified in  the related
Prospectus Supplement. In addition, some or  all of the Certificates of a  Class
may  be subject to  mandatory repurchase by or  on behalf of  the Sellers to the
extent, at the prices, on  the dates and under  the conditions specified in  the
related  Prospectus  Supplement.  On  the  date  on  which  any  Certificate  is
 
                                       35
<PAGE>
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 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.  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   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
 
                                       36
<PAGE>
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 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.
 
                                       37
<PAGE>
    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% 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
 
                                       38
<PAGE>
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 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
 
                                       39
<PAGE>
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 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.
 
                                       40
<PAGE>
        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
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
 
                                       41
<PAGE>
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 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."
 
                                       42
<PAGE>
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 supporting  distributions of  particular amounts to  the holders  of
Certificates of particular Classes, may, instead, support certain collections on
the  related Contract  Pool. These  collections may  be of  all or  a portion of
amounts due  on Contracts  in liquidation,  all or  a portion  of the  scheduled
monthly  payments due on the Contracts or  of other amounts. The extent to which
any such collections are supported by a Credit Facility which functions in  this
manner will be described in the applicable Prospectus Supplement.
 
LIQUIDITY FACILITIES
 
    The  Certificates of one or  more Classes may be  entitled to the benefit of
one or more certificate purchase agreements or other liquidity facilities (each,
a "Liquidity  Facility"),  pursuant to  which  the provider  of  such  Liquidity
Facility  (the "Liquidity Facility  Provider") will provide funds  to be used to
purchase some or  all of such  Certificates on the  Repurchase Dates  applicable
thereto.  Unless otherwise specified in  the applicable Prospectus Supplement, a
Liquidity Facility will  be held  outside of  the Trust  Fund by  a third  party
(which  may be the  Trustee acting in another  capacity). The related Prospectus
Supplement will  contain  a  description  of the  material  terms  of  any  such
Liquidity  Facility and any arrangement pursuant to  which it is held outside of
the Trust Fund, and  will contain certain  information concerning the  Liquidity
Facility  Provider, which information will have  been provided to the Sellers by
the Liquidity Facility Provider for use  in such Prospectus Supplement. Bank  of
America, 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 general discussion of the anticipated material federal  income
tax  consequences of the purchase, ownership  and disposition of Certificates of
any Series, to the extent it relates to matters of law or legal conclusions with
respect thereto, represents the  opinion of special counsel  to Bank of  America
and  Bank America Housing Services  with respect to that  Series on the material
matters associated with  such consequences,  subject to  any qualifications  set
forth  herein.  Special  counsel  to Bank  of  America  and  BankAmerica Housing
Services for each  Series will be  Morrison & Foerster  LLP, and a  copy of  the
legal  opinion  of  such  counsel  rendered in  connection  with  any  Series of
Certificates will be filed with the Commission  on a Current Report on Form  8-K
within  15 days after the  issuance of the related  Series of Certificates. This
discussion  is   directed  primarily   to  Certificateholders   that  hold   the
Certificates  as "capital assets" within the meaning of Section 1221 of the Code
(although portions thereof also may apply to Certificateholders who do not  hold
Certificates as "capital assets") and it does not purport to discuss all federal
income  tax consequences that may be  applicable to the individual circumstances
of particular investors, some of which  (such as banks, insurance companies  and
foreign  investors) may be subject to special treatment under the Code. Further,
the authorities on which this discussion, and the
 
                                       43
<PAGE>
opinion referred  to  below,  are  based are  subject  to  change  or  differing
interpretations,  which could apply  retroactively. Prospective investors should
note that no  rulings have  been or  will be  sought from  the Internal  Revenue
Service  (the  "Service")  with  respect  to  any  of  the  federal  income  tax
consequences discussed below,  and no assurance  can be given  that the  Service
will  not  take  contrary  positions. Taxpayers  and  preparers  of  tax returns
(including those filed by any REMIC or other issuer) should be aware that  under
applicable  Treasury regulations a provider of  advice on specific issues of law
is not considered an income tax return  preparer unless the advice (i) is  given
with respect to events that have occurred at the time the advice is rendered and
is  not given with respect to the consequences of contemplated actions, and (ii)
is directly  relevant  to  the  determination  of an  entry  on  a  tax  return.
Accordingly,  taxpayers  should  consult  their  tax  advisors  and  tax  return
preparers regarding the preparation of any item on a tax return, even where  the
anticipated  tax treatment has been discussed herein. In addition to the federal
income tax consequences  described herein,  potential investors  are advised  to
consider  the state, local and other tax  consequences, if any, of the purchase,
ownership  and  disposition  of  Certificates  in  a  Series.  See  "Other   Tax
Consequences".  Certificateholders  are advised  to  consult their  tax advisors
concerning the federal, state,  local or other tax  consequences to them of  the
purchase, ownership and disposition of Certificates in a Series.
 
    The  following  discussion addresses  securities of  two general  types: (i)
certificates ("REMIC Certificates") representing interests in a Trust Fund  with
respect to which an election to be treated as a "real estate mortgage investment
conduit"  ("REMIC") under Sections 860A through 860G (the "REMIC Provisions") of
the Code  will  be  made,  and  (ii)  Grantor  Trust  Certificates  representing
interests  in a Trust Fund  ("Grantor Trust Fund") as  to which no such election
will be made.
 
    The following discussion is based in part upon the rules governing  original
issue discount that are set forth in Sections 1271-1273 and 1275 of the Code and
in  the Treasury regulations  issued thereunder (the  "OID Regulations"), and in
part upon the REMIC  Provisions and the  Treasury regulations issued  thereunder
(the "REMIC Regulations"). The OID Regulations do not adequately address certain
issues  relevant to, and in some instances  provide that they are not applicable
to, securities such as the Certificates.
 
    The following discussion  is limited in  applicability to the  Certificates.
For  purposes of this  tax discussion, references to  a "Certificateholder" or a
"holder" are to the beneficial owner of a Certificate.
 
REMIC ELECTIONS
 
    Under the Code, an election may be made with respect to a Trust Fund related
to any  Series of  Certificates  to treat  such Trust  Fund  as a  "real  estate
mortgage  investment conduit" ("REMIC") within the meaning of Section 860D(a) of
the Code, in which  case the Certificates  of any Class of  such Series will  be
either "regular interests" in the REMIC within the meaning of Section 860G(a)(1)
of  the Code or "residual interests" in  the REMIC within the meaning of Section
860G(a)(2)  of  the  Code.  The   Prospectus  Supplement  for  each  Series   of
Certificates  will  indicate whether  each Seller  of  Contracts to  the related
Contract Pool intends to cause an election to be made to treat the Trust Fund as
a REMIC, and  if such  an election  is to be  made, which  Certificates will  be
regular  interests and  which will  be the residual  interest in  the REMIC. The
discussion under  the  heading "--  REMIC  Certificates" discusses  Series  with
respect  to which  each Seller  of Contracts to  the related  Contract Pool will
cause a REMIC  election to  be made  and the  discussion under  the heading  "--
Non-REMIC  Certificates" discusses Series with respect  to which the Sellers (or
if only one Seller sells Contracts to the related Contract Pool, the  applicable
Seller) will not cause a REMIC election to be made.
 
REMIC CERTIFICATES
 
    The  discussion in this section applies only to a Series of Certificates for
which a REMIC election is 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
 
                                       44
<PAGE>
with  any Underwriter, the Trust  Fund will be a  REMIC, and the Certificates of
such Series will be treated as either "regular interests" in the REMIC ("Regular
Certificates") or "residual interests" in the REMIC ("Residual Certificates").
 
    The following  general  discussion of  the  anticipated federal  income  tax
consequences  of the purchase, ownership  and disposition of REMIC Certificates,
to the extent it  relates to matters  of law or  legal conclusions with  respect
thereto,  represents the opinion of Morrison  & Foerster LLP, special counsel to
Bank of America and BankAmerica Housing Services, subject to any  qualifications
set  forth herein. In addition, Morrison & Foerster LLP, special counsel to Bank
of America  and BankAmerica  Housing  Services, have  prepared or  reviewed  the
statements  in this  Prospectus under  the heading  "Certain Federal  Income Tax
Consequences -- REMIC Certificates," and are of the opinion that such statements
are correct  in  all material  respects.  Such  statements are  intended  as  an
explanatory  discussion of  the possible  effects of  the classification  of any
Trust Fund as a REMIC for federal income tax purposes on investors generally and
of related tax  matters affecting  investors generally,  but do  not purport  to
furnish  information  in  the  level  of detail  or  with  the  attention  to an
investor's specific tax circumstances  that would be  provided by an  investor's
own  tax advisor. Accordingly, each  investor is advised to  consult its own tax
advisors with  regard  to the  tax  consequences to  it  of investing  in  REMIC
Certificates.
 
    A.  TAX STATUS  OF REMIC  CERTIFICATES.   Unless otherwise  specified in the
related  Prospectus  Supplement,  the  Certificates  of  any  Series,  in  their
entirety,  will  generally be  considered (i)  "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,
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
 
                                       45
<PAGE>
(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 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.
 
                                       46

    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, 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  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
 
                                       47
<PAGE>
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 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
 
                                       48
<PAGE>
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 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
 
                                       49
<PAGE>
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 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.
 
                                       50
<PAGE>
    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 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
 
                                       51
<PAGE>
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.
 
    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.
 
                                       52
<PAGE>
    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 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
 
                                       53
<PAGE>
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.
 
    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
 
                                       54
<PAGE>
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.
 
    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
 
                                       55
<PAGE>
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
 
                                       56
<PAGE>
Fund  will have the  effect of amortization  of the issue  price of the Residual
Certificates over the life of the Trust  Fund's assets. However, in view of  the
possible  acceleration  of  the  income  of  holders  of  Residual  Certificates
described above, the period of time  over which such issue price is  effectively
amortized may be longer than the economic life of the Residual Certificates.
 
    THE  METHOD OF TAXATION OF RESIDUAL CERTIFICATES DESCRIBED ABOVE CAN PRODUCE
A SIGNIFICANTLY LOWER AFTER-TAX YIELD FOR  A RESIDUAL CERTIFICATE THAN WOULD  BE
THE  CASE IF (I) RESIDUAL  CERTIFICATES WERE TAXABLE IN  THE SAME MANNER AS DEBT
INSTRUMENTS ISSUED BY THE TRUST FUND OR (II) NO PORTION OF THE TAXABLE INCOME ON
THE RESIDUAL CERTIFICATES IN EACH PERIOD WERE TREATED AS "EXCESS INCLUSIONS" (AS
DEFINED BELOW).  IN  CERTAIN  PERIODS,  TAXABLE INCOME  AND  THE  RESULTING  TAX
LIABILITY  ON  A RESIDUAL  CERTIFICATE ARE  LIKELY  TO EXCEED  PAYMENTS RECEIVED
THEREON. IN ADDITION, A SUBSTANTIAL TAX MAY BE IMPOSED ON CERTAIN TRANSFERORS OF
THE  RESIDUAL  CERTIFICATES  AND  CERTAIN  BENEFICIAL  OWNERS  OF  THE  RESIDUAL
CERTIFICATES  THAT ARE "PASS-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
 
                                       57
<PAGE>
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 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
 
                                       58
<PAGE>
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 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
 
                                       59
<PAGE>
if the record holder  furnishes the pass-through entity  with an affidavit  that
the  record holder is not  a disqualified organization, and,  as of the time the
record holder  becomes such  a holder,  the pass-through  entity does  not  have
actual knowledge that such affidavit is false.
 
    For  these  purposes, the  term  "disqualified organization"  means  (i) the
United States, any State or political subdivision thereof, any possession of the
United States, any  foreign government, any  international organization, or  any
agency  or instrumentality of the foregoing  (other than an instrumentality that
is a corporation if all of its activities are subject to tax and, except for the
Federal Home Loan Mortgage Corporation, a majority of its board of directors  is
not  selected by an such governmental unit),  (ii) an organization (other than a
cooperative described in Section 521 of  the Code) which is exempt from  federal
income  tax (including the tax  imposed by Section 511  of the Code on unrelated
business  taxable  income)  on  excess  inclusions  or  (iii)  any  organization
described  in Section  1381(a)(2)(C) of the  Code. For these  purposes, the term
"pass-through entity"  means  any  regulated  investment  company,  real  estate
investment  trust,  common trust  fund, partnership,  trust, estate  and certain
other entities described  in Section 860E(e)(6)  of the Code.  Except as may  be
provided   in  Treasury  Regulations,  any  person  holding  an  interest  in  a
pass-through entity  as  a  nominee  for another  will,  with  respect  to  such
interest, be treated as a pass-through entity.
 
    10.  SALE OR EXCHANGE.  If a  Residual Certificate is sold or exchanged, the
seller will recognize gain or loss equal to the difference, if any, between  the
amount  realized and its adjusted basis  in the Residual Certificate (as defined
above in "-- 2.  Distributions") at the  time of such  sale or exchange  (except
that  the  recognition of  a loss  may be  limited under  the "wash  sale" rules
described below). In  general, any such  gain or  loss will be  capital gain  or
loss, provided the Residual Certificate is held as a capital asset as defined in
Section  1221 of the Code. However, a  Residual Certificate will be an "evidence
of indebtedness" within the  meaning of Section 582(c)(1)  of the Code, so  that
gain  or loss recognized  from the sale of  a Residual Certificate  by a bank or
thrift institution to  which such section  applies would be  ordinary income  or
loss.
 
    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
 
                                       60
<PAGE>
paid  its debts as they  came due and found  no significant evidence to indicate
that the transferee will not continue to pay  its debts as they come due in  the
future  and (ii) the transferee represents to the transferor that it understands
that, as the  holder of  a non-economic  residual interest,  the transferee  may
incur  tax liabilities in excess of any cash flows generated by the interest and
that the transferee intends  to pay taxes associated  with holding the  residual
interest  as they become due. The Agreement with respect to each Series of REMIC
Certificates will require the transferee of a Residual Certificate to certify to
the statements in clause (ii) of the preceding sentence as part of the affidavit
described below under "Restrictions on Transfer of REMIC Residual Certificates."
 
    12. TERMINATION.  The  Trust Fund related to  a Series of Certificates  will
terminate  shortly following the retirement of Certificates in such Series. If a
Residual Certificateholder's adjusted basis in its Residual Certificate  exceeds
the  amount  of cash  distributed to  such  Residual Certificateholder  in final
liquidation of its interest, then, although the matter is not entirely free from
doubt, it would appear that the Residual Certificateholder is entitled to a loss
equal to the amount of such excess.
 
    13.  FOREIGN  INVESTORS.    Unless  otherwise  provided  in  the  applicable
Prospectus  Supplement, no record or beneficial ownership interest in a Residual
Certificate may be transferred to a 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
 
                                       61
<PAGE>
according to an amortization schedule or according to some other method. Because
of  the  uncertainty  concerning  the treatment  of  such  payments,  holders of
Residual Certificates should consult their tax advisors concerning the treatment
of such payments for income tax purposes.
 
    E.  OTHER   MATTERS   RELATING   TO   REMIC   CERTIFICATES;   ADMINISTRATIVE
MATTERS.   Solely for the purposes of the administrative provisions of the Code,
each Trust  Fund for  which  a REMIC  election  is made  will  be treated  as  a
partnership, and the Residual Certificateholders will be treated as the partners
thereof.  The Trust Fund  must maintain its  books on a  calendar year basis and
must file federal information returns in  a manner similar to a partnership  for
federal  income  tax  purposes.  Certain information  on  such  returns  will be
furnished to  each  Residual Certificateholder.  The  Trust Fund  also  will  be
subject  to the  procedural and administrative  rules of the  Code applicable to
partnerships, including rules  for determining  any adjustments  to among  other
things, items of REMIC income, gain, loss, deduction or credit by the Service in
a  unified administrative proceeding. The  holders of Residual Certificates will
generally be entitled to participate in audits of the Trust Fund by the  Service
to  the same extent  as general partners  in an audit  of a partnership, Regular
Certificateholders will not be entitled to participate in any such audits.
 
    Each Residual Certificateholder  is required  to treat items  on its  return
consistently  with  their  treatment  on the  Trust  Fund's  return,  unless the
Residual  Certificateholder   either   files   a   statement   identifying   the
inconsistency  or  establishes that  the  inconsistency resulted  from incorrect
information received from the  Trust Fund. The Service  may assert a  deficiency
resulting  from a  failure to  comply with  the consistency  requirement without
instituting an administrative proceeding at the Trust Fund level. The Trust Fund
does not intend to  register as a  tax shelter pursuant to  Section 6111 of  the
Code  because it is not anticipated that the Trust Fund will have a net loss for
any of the first five  taxable years of its existence.  Any person that holds  a
Residual Certificate as a nominee for another person will be required to furnish
the  Trust Fund, in a manner provided in Treasury Regulations, with the name and
address of such person, and other information.
 
    Each Residual Certificateholder, by purchasing its Residual Certificate, (A)
shall be deemed to consent  to the appointment of the  Servicer as (i) the  "tax
matters  person" (within  the meaning  of Section  1.860F --  4(d) of  the REMIC
Regulations) for the  Trust Fund  and (ii)  attorney-in-fact and  agent for  any
person  that is the tax matters person if the Servicer is unable to serve as the
tax matters person,  and (B) agrees  to execute any  documents required to  give
effect to (A) above.
 
NON-REMIC CERTIFICATES
 
    The  discussion under this heading applies  only to a Series of Certificates
with respect to which a REMIC election is not made ("Non-REMIC Certificates").
 
    A. CHARACTERIZATION OF THE TRUST FUND.   Upon the issuance of any Series  of
Certificates  with  respect  to which  no  REMIC  election is  made,  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
 
                                       62
<PAGE>
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 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
 
                                       63
<PAGE>
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
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
 
                                       64
<PAGE>
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 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
 
                                       65
<PAGE>
Residual Certificates -- 9. Tax on Transfers of Residual Certificates to Certain
Organizations"),  (ii)  a representation  from  the proposed  transferee  to the
effect that it is  a citizen or  resident of the  United States, a  corporation,
partnership  or other entity  created or organized  in or under  the laws of the
United States or any political subdivision thereof, or an estate or trust  whose
income  from sources without the United States is includable in gross income for
United States federal income tax purposes regardless of its connection with  the
conduct  of a trade or business within the United States and (iii) a covenant of
the proposed transferee to the effect that the proposed transferee agrees to  be
bound  by and  to abide  by the transfer  restrictions applicable  to such REMIC
Residual Certificate.
 
                              TAX-EXEMPT INVESTORS
 
    A qualified pension plan or other entity that is exempt from federal  income
taxation  pursuant  to  Section  501  of  the  Code  (a  "Tax-Exempt  Investor")
nonetheless will be subject  to federal income taxation  to the extent that  its
income  is "unrelated  business taxable income"  ("UBTI") within  the meaning of
Section 512 of the  Code. All "excess  inclusions" of a  "REMIC" allocated to  a
"Residual Certificate" held by a Tax-Exempt investor will be considered UBTI and
thus  will be  subject to  federal income tax.  See "Certain  Federal Income Tax
Consequences  --  Certificates  as  REMIC   Residual  Interests  --  7.   Excess
Inclusions."
 
                                LEGAL INVESTMENT
 
    The  Prospectus  Supplement for  each  Series of  Certificates  will specify
which, if  any,  of  the  Classes of  Certificates  offered  thereby  constitute
"mortgage  related  securities" for  purposes of  the Secondary  Mortgage Market
Enhancement Act  of 1984  ("SMMEA").  Classes of  Certificates that  qualify  as
"mortgage  related securities"  will be  legal investments  for persons, trusts,
corporations, partnerships, associations, business trusts and business  entities
(including  depository institutions, life insurance companies and pension funds)
created pursuant to or existing  under the laws of the  United States or of  any
state  (including the  District of  Columbia and  Puerto Rico)  whose authorized
investments are  subject  to state  regulation  to  the same  extent  as,  under
applicable law, obligations issued by or guaranteed as to principal and interest
by  the United  States or  any such  entities. Under  SMMEA, if  a state enacted
legislation prior to October 4, 1991 specifically limiting the legal  investment
authority  of any such  entities with respect  to "mortgage related securities,"
Certificates will  constitute legal  investments for  entities subject  to  such
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
 
                                       66
<PAGE>
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,
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.
 
                                       67
<PAGE>
    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.
 
    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  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
 
                                       69
<PAGE>
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  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.
 
    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,
 
                                       71
<PAGE>
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 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.
 
                                       72
<PAGE>
    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 specified in the
related Prospectus Supplement. A security rating is not a recommendation to buy,
sell or hold securities and may be subject to revision or withdrawal at any time
by the  assigning  rating  agency.  Each security  rating  should  be  evaluated
independently of any other security rating.
 
                             METHOD OF DISTRIBUTION
 
    The  Sellers may sell Certificates of each Series to or through underwriters
(the "Underwriters") by  a negotiated  firm commitment  underwriting and  public
reoffering  by  the  Underwriters,  and also  may  sell  and  place Certificates
directly to  other  purchasers  or  through  agents.  The  Sellers  intend  that
Certificates  be offered through such various methods from time to time and that
offerings may be  made concurrently through  more than one  of these methods  or
that  an offering of a  particular Series of Certificates  may be made through a
combination of such methods.
 
    This Prospectus and  any related  Prospectus Supplement  may be  used by  BA
Securities,  Inc., an  affiliate of the  Sellers, in connection  with offers and
sales related to market making transactions  in any Series of the  Certificates.
BA  Securities, Inc. may  act as principal  or agent in  such transactions. Such
sales will be made at prices related to prevailing market prices at the time  of
the sale.
 
    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
 
                                       73
<PAGE>
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
 
                                       74
<PAGE>
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.
