      CONSIDER CAREFULLY THE
 RISK FACTORS STARTING ON
 PAGE S-14 OF THIS
 PROSPECTUS SUPPLEMENT AND
 PAGE 15 OF THE PROSPECTUS
 BEFORE MAKING A DECISION TO
 INVEST IN THE NOTES.
 
      The notes represent
 mortgage-backed debt
 secured solely by the
 mortgage loans held by the
 trust. The notes are not
 interests in or obligations
 of any other person. No
 governmental agency or
 instrumentality has insured
 or guaranteed the notes or
 the underlying mortgage
 loans.
 
      This prospectus
 supplement may be used to
 offer and sell the notes
 only if accompanied by a
 prospectus.
                          THE ISSUER
 
                          - is a Delaware business trust formed pursuant to a
                            trust agreement between Bear Stearns Asset Backed
                            Securities, Inc., as depositor, and Wilmington Trust
                            Company, as owner trustee.
 
                          - will issue a single class of its mortgage-backed
                            notes for sale by this prospectus supplement.
 
                          THE NOTES
 
                          - are principally secured by the assets of the trust,
                            which consist primarily of fixed and adjustable rate
                            mortgage loans secured by first liens on one- to
                            four-family residential properties.
 
                          - interest and principal on the notes is scheduled to
                            be paid monthly on the 25th day of the month or, if
                            such day is not a business day, the immediately
                            following business day. The first scheduled payment
                            date is May 25, 1999.
 
                          THE MORTGAGE LOANS
 
                          - were originated under underwriting guidelines less
                            stringent than those applied by Fannie Mae and
                            Freddie Mac and, therefore, are likely to experience
                            higher rates of delinquency, foreclosure and
                            bankruptcy than those experienced by mortgage loans
                            underwritten under Fannie Mae or Freddie Mac
                            guidelines. See "Risk Factors" herein.
 
                          CREDIT ENHANCEMENT
 
                          - on the issue date of the notes, the aggregate stated
                            principal balance of the mortgage loans of the trust
                            pledged to secure the notes will exceed the
                            principal balance of the notes resulting in
                            overcollateralization which will be available to
                            absorb losses. Thereafter, principal payments on the
                            notes will be made to maintain overcollateralization
                            at specified levels.
 
                          - as described herein, the notes will also be insured
                            pursuant to the terms of a financial guaranty
                            insurance policy issued by:
 
                    [FINANCIAL SECURITY ASSURANCE(R) LOGO]
 
     The underwriter named below will offer the Notes to the public from time to
time in negotiated transactions or otherwise at varying prices to be determined
at the time of sale. The underwriter will pay the depositor an amount equal to
approximately 99.70% of the aggregate principal balance of the Notes, plus
accrued interest, before deducting issuance expenses payable by the depositor.
The notes will be issued in book-entry form only on or about April 15, 1999
through the facilities of The Depository Trust Company, Cedelbank or the
Euroclear system.

DESCRIPTION OF THE NOTES
 
THE NOTES
 
     The trust will issue its mortgage-backed notes, designated as the "American
Residential Eagle Bond Trust 1999-1, Mortgage-Backed LIBOR Notes, Class A,
Series 1999-1".
 
     The initial principal balance of the notes, as indicated on the front cover
of this prospectus supplement, is subject to a variance of plus or minus 5.00%.
 
THE ASSETS OF THE TRUST
 
     The notes are secured by a pledge of assets of the trust. The trust's
assets pledged to secure the notes include:
 
- - a pool of fixed and adjustable rate mortgage loans secured by first liens on
  one- to four-family residential properties and with original terms to maturity
  of not more than 30 years;
 
- - principal and interest payments (but not including prepayment charges) on the
  mortgage loans due on or after April 1, 1999;
 
- - a security interest in the related underlying residential property (and in
  certain hazard insurance policies covering the property);
 
- - amounts on deposit in certain accounts described in this prospectus
  supplement; and
 
- - a primary mortgage insurance policy covering substantially all those mortgage
  loans in the mortgage pool with loan-to-value ratios in excess of 80%.
 
     In addition, the noteholders will have the benefit of a financial guaranty
insurance policy to be issued to the Trust by Financial Security Assurance Inc.
 
     See "The Trust," "Description of the Notes -- General" and "The Insurance
Policy" in this Prospectus Supplement.
 
STATED MATURITY OF THE NOTES
 
     The stated maturity date of the notes, on which the final payment of
principal must ultimately be made, is April 25, 2029, which is the payment date
that occurs in the third month following the month in which the last maturity
date of any mortgage loan conveyed to the trust is scheduled to occur. The
depositor anticipates, however, that the actual final payment of principal on
the notes will occur significantly earlier.
 
     See "Certain Prepayment and Yield Considerations" in this Prospectus
Supplement.
 
REGISTRATION OF THE NOTES
 
     The trust will issue the notes in book-entry form in minimum denominations
of $50,000 and multiples of $1 in excess thereof. You will hold your interests
in the notes either through The Depository Trust Company in the United States or
through Cedelbank or the Euroclear system in Europe. For as long as the notes
are in book-entry form, they will be registered in the name of the applicable
depository, or in the name of the depository's nominee. The limited
circumstances under which definitive certificated notes will replace book-entry
notes are described in this prospectus supplement.
 
     See "Description of the Notes -- Book-Entry Registration and Definitive
Notes" in this Prospectus Supplement.
 
PAYMENT ON THE NOTES
 
PAYMENT DATES
 
     Principal and interest is scheduled to be paid to the noteholders on the
25(th) day of each month, or, if such day is not a business day, on the
following business day, commencing on May 25, 1999.
 
                                       S-5
<PAGE>   6
 
RECORD DATES
 
     The indenture trustee will make payments to the noteholders of record
determined as of the last business day immediately prior to the payment date or,
in the event notes are issued in definitive form, the last day of the calendar
month immediately prior to the payment date.
 
DUE PERIODS AND COLLECTION PERIODS
 
     Generally, payments made to noteholders on each payment date will relate to
collections of principal and interest on the mortgage loans in the due period
with respect to all scheduled collections of principal and interest, or the
collection period, with respect to all unscheduled collections. The "due period"
commences on the second day of the calendar month immediately before the month
in which the related payment date occurs (or, in the case of the first
Distribution Date, on the Cut-off Date) and ends on the first day of the month
in which the related payment date occurs. The "collection period" is the
calendar month before the calendar month in which the related payment date
occurs.
 
FUNDS AVAILABLE FOR PAYMENT OF INTEREST AND PRINCIPAL
 
     The following funds will generally be available for payment of interest and
principal on the notes:
 
- - scheduled collections on the mortgage loans received during the related due
  period, net of servicing fees, reimbursement of previous advances made by the
  master servicer, and other fees and expenses in connection with this
  transaction including, without limitation, premiums on insurance policies and
  fees and expenses of the indenture trustee, the owner trustee, and the
  manager;
 
- - unscheduled collections on the mortgage loans received during the related
  collection period including, among other items, (i) partial and full
  prepayments, (ii) net proceeds from insurance policies covering a mortgaged
  property and (iii) any other proceeds, net of expenses, the master servicer
  receives in connection with a defaulted mortgage loan, as a result of the
  sale, foreclosure, condemnation or other disposition of the related mortgaged
  property;
 
- - any advances made by the master servicer in respect of delinquent payments of
  interest on the mortgage loans;
 
- - interest payments made by the master servicer to compensate the noteholders in
  part for any shortfall in interest payments on the notes caused by a mortgagor
  prepaying a mortgage loan in whole or in part;
 
- - any amounts resulting from the repurchase, release, removal or substitution of
  a mortgage loan; and
 
- - in the event the notes are redeemed in the manner described herein, amounts
  deposited in connection with such redemption.
 
     See "Description of the Notes--Payment on the Notes."
 
INTEREST PAYMENTS
 
     General.  Interest will accrue on the notes at the note interest rate
during each interest accrual period. An interest accrual period is the period
commencing on the prior payment date (or in the case of the first payment date,
beginning on the closing date) and ending on the date immediately preceding such
payment date. The indenture trustee will calculate interest based upon the
actual number of days in the interest accrual period and a year assumed to
consist of 360 days. Interest payments will be made to noteholders on a pro rata
basis.
 
     Calculation of the Note Interest Rate. The note interest rate on each
payment date up to and including the payment date on which the trust is first
permitted to redeem the notes (see "-- Redemption of the Notes" below) will be
equal to the lesser of (i) a per annum floating rate equal to one-month LIBOR
for the related interest accrual period plus 0.35% and (ii) 15.00% per annum.
Thereafter, if the trust does not exercise its optional redemption rights when
first permitted to do so, the note interest rate will be equal to the lesser of
(i) a per annum floating rate equal to one-month LIBOR for the related interest
accrual period plus
 
                                       S-6
<PAGE>   7
 
0.70% and (ii) 15.00% per annum. One-month LIBOR for each interest accrual
period will be determined by the indenture trustee according to the formula
described in this prospectus supplement.
 
     Overall Limitation on the Note Interest Rate.  Because a majority of the
mortgage loans securing payment of the notes bear adjustable interest rates (i)
which adjust based on changes in the six-month LIBOR index and, therefore, less
frequently than the note interest rate which adjusts monthly based on one-month
LIBOR, (ii) have delayed adjustment dates ranging from two to five years after
their origination date, and (iii) are subject to limitations on periodic
interest rate increases and maximum interest rates over the life of the loan
which may be less than one-month LIBOR, the amount of interest collections on
the mortgage loans for the related interest accrual period may be less than
interest accrued on the notes at the note interest rate. In addition, a higher
than expected rate of prepayment of mortgage loans in the mortgage pool with
relatively higher mortgage rates would contribute to this shortfall. In this
connection, it should be noted that approximately 28% of the mortgage loans in
the mortgage pool as of March 1, 1999 (based on principal balances) have
interest rates that are fixed for the lives of those mortgage loans.
 
     For the above reasons, as an overall limitation on the note interest rate,
if as of any payment date the note interest rate as calculated above exceeds the
weighted average net loan rate (calculated as described in this prospectus
supplement) of the mortgage loans for the related due period, then the note
interest rate for the related interest accrual period will be limited to such
weighted average net loan rate.
 
     See "Description of the Notes -- Note Interest Rate" in this Prospectus
Supplement.
 
     Supplemental Interest Payments.  Supplemental interest payments will be
made by Financial Security Assurance Inc. under the financial guaranty insurance
policy as described herein. Such payments are intended to provide noteholders
with an additional interest payment to partially compensate for the difference
between (i) the amount of interest that accrued on the notes for the related
interest accrual period at the note interest rate (calculated without regard to
the overall available funds limitation described above) and (ii) the amount of
interest that accrued on the notes (calculated with regard to such overall
available funds limitation). However, because these payments are limited in
amount as described in this prospectus supplement, the supplemental interest
payment made to noteholders may be less than this difference.
 
     See "Description of the Notes -- Supplemental Interest Payments" in this
Prospectus Supplement.
 
PRINCIPAL PAYMENTS
 
     On each payment date, to the extent that funds are available, you will be
entitled to payments of principal as described in this prospectus supplement.
The maximum amount of payment of principal to all noteholders on any payment
date will be the sum of:
 
- - all scheduled payments of principal made on the mortgage loans and all
  unscheduled payments of principal collected, received or otherwise recovered
  on the mortgage loans as described above under "-- Funds Available for Payment
  of Interest and Principal";
 
- - plus, the amount of any excess receipts of interest required to be distributed
  as principal to satisfy the required level of overcollateralization. This will
  increase the difference between the principal balance of the notes and the
  principal balance of the mortgage loans, thereby increasing the level of
  overcollateralization; and
 
- - minus, the amount, if any, necessary to reduce the required level of
  overcollateralization. This will reduce the difference between the principal
  balance of the notes and the principal balance of the mortgage loans, thereby
  decreasing the level of overcollateralization.
 
                                       S-7
<PAGE>   8
 
     Shortfalls in collections on the mortgage loans and the failure of the note
insurer to perform its obligations under the insurance policy may result in
noteholders receiving less principal than what is owed to them.
 
     See "Description of the Notes -- Payment on the Notes -- Priority of
Payments."
 
MONTHLY ADVANCES
 
     The master servicer will be required to make advances with respect to
delinquent payments of interest on the mortgage loans. However, the master
servicer is only required to make such advances if it believes it can recover
the advance from later proceeds or collections on the related mortgage loan. The
master servicer will be entitled to reimburse itself for any such advances from
future payments and collections (including insurance payments or liquidation
proceeds) with respect to the mortgage loans. However, if the master servicer
makes advances which are nonrecoverable from future payments and collections,
the master servicer will be entitled to reimbursement for such advances prior to
any payments to noteholders.
 
     See "Servicing of the Mortgage Loans -- The Master Servicing Agreement" in
this Prospectus Supplement.
 
COMPENSATORY INTEREST PAYMENTS
 
     The master servicer will also make interest payments to compensate in part
for any shortfall in interest payments on the notes which result from a
mortgagor prepaying a mortgage loan in whole or in part. However, the master
servicer will not be obligated to pay any amounts due to the application of the
Soldier's and Sailor's Relief Act of 1940. The amount of such payments will not
exceed the servicing fees payable to the master servicer for the related due
period. The financial guaranty insurance policy does not cover shortfalls in
interest arising from prepayments.
 
     See "Servicing of the Mortgage Loans -- The Master Servicing Agreement" in
this Prospectus Supplement.
 
REDEMPTION OF THE NOTES
     The trust, at the direction of the holder of the trust certificate in the
trust, will have the option to redeem all, but not less than all, the notes on
any payment date after which the aggregate outstanding principal balance of the
mortgage loans is 20% or less of the aggregate principal balance of the mortgage
loans as of April 1, 1999. The redemption price generally must equal 100% of the
unpaid principal balance of the notes, plus accrued and unpaid interest thereon
at the note interest rate, plus (i) any unreimbursed servicing fees and advances
owed to the master servicer and (ii) any amounts owed to the note insurer, the
indenture trustee and the owner trustee. If the trust does not exercise its
mandatory redemption rights on the first payment date on which it is permitted
to do so, on such payment date and all succeeding payment dates the note
interest rate will increase as described at "-- Calculation of the Note Interest
Rate" above. However, in any such case, the note interest rate will be limited
to the available funds limitations described above at "-- Overall Limitation on
the Note Interest Rate."
 
     See "Description of the Notes -- Redemption of the Notes" in this
Prospectus Supplement.
 
TERMINATION OF THE MORTGAGE POOL
 
     After the payment date upon which the aggregate outstanding principal
balance of the mortgage loans is equal to 10% or less of the aggregate principal
balance of the mortgage loans as of April 1, 1999, the indenture trustee will
solicit bids to purchase the remaining mortgage loans at their market value.
 
     The indenture trustee, with the prior consent of the note insurer, will
sell the mortgage loans only if (i) the indenture trustee receives at least
three bids on the mortgage loans, (ii) the highest bid is equal to or greater
than the fair market value of the mortgage loans and (iii) the highest bid, when
added to any amounts available on such payment date, equals or exceeds the sum
of (a) all interest due on the notes, (b) the aggregate remaining note
 
                                       S-8
<PAGE>   9
 
balance, and (c) any accrued and unpaid amounts due to the note insurer, the
master servicer, the indenture trustee and the owner trustee, and (d) the
indenture trustee receives an opinion of counsel stating that the sale will not
result in adverse tax consequences to the issuer, the noteholders and the tax
characterization of the trust. Any such proposed purchase of the mortgage loans
by the highest bidder will be subject to the right of first refusal of the
seller (or the master servicer, if the seller does not exercise its first
refusal right) to purchase the mortgage loans at such bid price.
 
     If the indenture trustee sells the mortgage loans, the proceeds of the sale
will be used to redeem the notes in full, and any excess (after payment of the
amounts described in clause (c) above) shall go to the holder of the residual
interest. See "-- Trust Certificate" herein. The indenture trustee will solicit
bids on a quarterly basis if the requirements for a sale listed above are not
met.
 
     See "Description of the Notes -- Termination of the Trust" in this
Prospectus Supplement.
 
CREDIT ENHANCEMENT
 
     Credit enhancement reduces the harm caused to noteholders by shortfalls in
collections received and losses incurred on the mortgage loans. The credit
enhancement available to noteholders will consist of (a) excess cash, (b)
overcollateralization and (c) the insurance policy issued by Financial Security
Assurance Inc., the note insurer.
 
EXCESS CASH
 
     Generally, because the payments of interest and principal on the mortgage
loans will exceed the sum of amounts payable to the note insurer, the master
servicer, the indenture trustee, the manager and the mortgage insurer and the
payments of monthly interest and principal to the noteholders, there will be
excess cash each month above that required to pay principal and interest on the
notes. Such excess cash will be applied to pay down the note balance in order to
maintain the required level of overcollateralization.

OVERCOLLATERALIZATION
 
     Credit support for the notes will be provided through limited
overcollateralization, i.e., the pledge of mortgage loans by the trust having an
aggregate stated principal balance in excess of the principal balance of the
notes. The purpose of overcollateralization is to ensure that there are excess
funds available to pay interest and principal on the notes so that noteholders
will have some protection against payment shortfalls and so that the note
balances will be reduced to zero no later than the date the notes are scheduled
to mature. After the closing date, the indenture trustee will make principal
payments on the notes on each payment date, to the extent of excess funds
available therefor, in an amount up to the amount necessary to achieve or
maintain overcollateralization at specified levels. Once the required level of
overcollateralization is reached, the application of excess funds to pay down
principal on the notes will cease, until such application is again needed to
maintain the required level of overcollateralization.
 
     The required amount of overcollateralization is based on certain minimum
and maximum levels of overcollateralization and on the performance of the
mortgage loans. As a result, the level of required overcollateralization will
increase and decrease over time. An increase in the required level of
overcollateralization will result if the delinquency or default experience on
the mortgage loans exceeds certain specified levels. In that event, payment of
principal on the notes would be accelerated until the level of
overcollateralization reached its required level.
 
     See "Description of the Notes -- Overcollateralization" in this Prospectus
Supplement.
 
THE INSURANCE POLICY
 
     General.  Financial Security Assurance Inc. will issue its financial
guaranty insurance policy to the indenture trustee for the benefit of
noteholders which unconditionally guarantees
 
                                       S-9
<PAGE>   10
 
the payment, to the extent not covered by principal and interest collections,
of:
 
- - accrued and unpaid interest due on the notes;
 
- - the amount of any supplemental interest payment, if any;
 
- - principal losses on the mortgage loans, to the extent not covered by
  overcollateralization;
 
- - any principal amount still owing to noteholders on the maturity date of the
  notes; and
 
- - any amounts previously distributed on the notes to noteholders that are
  recoverable and sought to be recovered as a voidable preference payment by a
  bankruptcy court.
 
     Payments Not Insured by the Insurance Policy.  The insurance policy WILL
NOT insure the payment of the following:
 
- - any shortfall arising because the trust or the indenture trustee incurred
  liability for withholding taxes;
 
- - any shortfall in interest as a result of prepayments on the mortgage loans;
 
- - shortfalls in interest due to the application of the Soldier's and Sailors'
  Relief Act of 1940, as amended;
 
- - shortfalls in monthly interest payments on the notes due to the applicability
  of the available funds limitation on the note interest rate to the extent not
  covered by supplemental interest payments made by the note insurer as
  described herein; and
 
- - any shortfalls created when the liquidation of a mortgaged property yields
  less than the principal amount owed on the loan, except to the extent that
  such shortfall is not covered by overcollateralization.
 
     See "The Insurance Policy" in this Prospectus Supplement.
 
MORTGAGE LOAN POOL
 
GENERAL
 
     As of April 1, 1999 the pool of mortgage loans securing the notes will
consist of approximately 1,336 adjustable rate and 719 fixed rate mortgage loans
having an aggregate principal balance of approximately $170,929,583 and
$65,356,313, respectively. These balances reflect an additional 14 fixed rate
mortgage loans and 36 adjustable rate mortgage loans having an aggregate
principal balance of approximately $6,830,924 as of April 1, 1999 which are
expected to be added to the mortgage pool on the closing date.
 
STATISTICAL INFORMATION
 
     The statistical information on the mortgage loans presented in this
prospectus supplement is based on a pool of mortgage loans as of March 1, 1999.
Such information does not take into account amortization, account default,
delinquencies and prepayments that may have occurred with respect to the
mortgage loans since such date, as well as the addition of mortgage loans to the
mortgage pool as described above. As a result, the statistical distribution of
the characteristics in the final mortgage pool as of the closing date will vary
from the statistical distribution of such characteristics in the mortgage pool
as presented in this prospectus supplement, although such variance will not be
material.
 
MORTGAGE LOAN DATA
 
     The pool of mortgage loans securing the notes will consist of approximately
1,300 adjustable rate and 705 fixed rate mortgage loans having an aggregate
principal balance as of March 1, 1999 of $233,114,644. All the mortgage loans
are secured by first liens on residen-

TRUST CERTIFICATE
 
     On the same day as the issue date of the notes, the trust will also issue a
trust certificate or residual interest which represents an ownership interest in
the mortgage loans and other assets of the trust but which is subordinate in
priority to payment of the notes. American Residential Eagle, Inc., the seller,
will initially hold the trust certificate. The trust certificate is not offered
by this prospectus supplement and the accompanying prospectus.
MATERIAL FEDERAL INCOME TAX CONSEQUENCES
 
     In the opinion of Jeffers, Wilson, Shaff & Falk, LLP, special tax counsel
to the seller, the notes will be characterized as debt for federal income tax
purposes and the trust will not be characterized as an association (or a
publicly traded partnership) taxable as a corporation or as a taxable mortgage
pool. The issuer and the depositor agree and each noteholder, by acceptance of a
note, will agree to treat the notes as indebtedness for federal, state and local
income tax and franchise tax purposes.
 
     See "Certain Federal Income Tax Considerations" in this Prospectus
Supplement.
 
ERISA CONSIDERATIONS
 
     Subject to the considerations discussed under "ERISA Considerations"
herein, the notes may be acquired and held by employee benefit plans and other
retirement plans and arrangements subject to the provisions of The Employee
Retirement Income Security Act of 1974, as amended, or Section 4975 of the
Internal Revenue Code of 1986, as amended.
 
     See "ERISA Considerations" in this Prospectus Supplement.
 
LEGAL INVESTMENT CONSIDERATIONS
 
     The notes will constitute "mortgage related securities" for purposes of the
Secondary Mortgage Market Enhancement Act of 1984, as amended. There may be
other restrictions on the ability of certain types of investors to purchase the
notes that investors should consider.
 
     See "Legal Investment Considerations" in this Prospectus Supplement.
 
RATING OF THE NOTES
 
     Before the trust can issue the notes, the notes must receive a rating of
"AAA" from Standard & Poor's, a division of The McGraw-Hill Companies, Inc., and
a rating of "Aaa" from Moody's Investors Service, Inc. Such ratings are
primarily based upon the creditworthiness of the note insurer, Financial
Security Assurance Inc.
                                      S-12
<PAGE>   13
 
     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
organization. A security rating does not address the frequency of principal
prepayments or the corresponding effect on yield to investors. In addition, a
security rating does not address the likelihood of payment of any interest
shortfall to the investors caused by the applicability of the available funds
limitation on the note interest rate to the extent not covered by supplemental
interest payments as described herein.
 
     See "Ratings" in this Prospectus Supplement.

<PAGE>   14
 
                                  RISK FACTORS
 
     Prospective investors in the notes should consider the following risk
factors (as well as the factors set forth under "Risk Factors" in the
Prospectus) in connection with the purchase of the notes. Any statistical
information presented below is based upon the characteristics of the mortgage
loans as of March 1, 1999 (referred to herein as the "Statistical Cut-off Date")
and, accordingly, such information does not take into account amortization,
defaults, delinquencies and prepayments that may have occurred with respect to
the mortgage loans in the mortgage pool since such date.
 
THE NOTES ARE NOT SUITABLE INVESTMENT FOR ALL INVESTORS.
 
     The notes are not suitable investments for any investor that requires a
regular or predictable schedule of payments or payments on a specific date. The
notes are complex investments that should be considered only by investors who,
either alone or with their financial, tax and legal advisors, have the expertise
to analyze the prepayment, reinvestment default and market risk, the tax
consequences of an investment, and the interaction of these factors.
 
AS A RESULT OF THE UNDERWRITING STANDARDS, THE MORTGAGE LOANS ARE LIKELY TO
EXPERIENCE HIGHER RATES OF DELINQUENCY, FORECLOSURE AND BANKRUPTCY THAN THOSE
UNDERWRITTEN IN A MORE TRADITIONAL MANNER.
 
     The mortgage loans included in the mortgage pool were originated by various
banks, savings and loan associations, mortgage brokers and mortgage lending
institutions and purchased by American Residential Investment Trust, Inc. either
directly from such originators or in the secondary market. Although the
underwriting criteria applied by such originators varies, a significant
consideration in underwriting a mortgage loan under their underwriting
guidelines is not only to assess the credit profile of the prospective borrower,
but also the value of the related mortgaged property and the adequacy of such
property as collateral for a mortgage loan. Such mortgage loans were made
primarily to borrowers whose income and credit history at the time did not
qualify for loans under the more stringent underwriting standards applied by
other mortgage loan purchase programs such as those run by Fannie Mae and
Freddie Mac, but who, nevertheless, had equity in their property. For example,
the mortgage loans may have been made to mortgagors having imperfect credit
histories, ranging from minor delinquencies to bankruptcies, or mortgagors with
higher ratios of monthly mortgage payments to income or higher ratios of total
monthly credit payments to income.
 
     As a result of the originators' underwriting standards, the mortgage loans
are likely to experience rates of delinquency, foreclosure and bankruptcy that
are higher, and that may be substantially higher, than those experienced by
mortgage loans underwritten in a more traditional manner. Furthermore, changes
in the values of mortgaged properties may have a greater effect on the
delinquency, foreclosure, bankruptcy and loss experience of the mortgage loans
in the mortgage pool than on mortgage loans originated under stricter
guidelines. There also can be no certainty that the values of the underlying
mortgaged properties have remained or will remain at the levels in effect on the
dates the related mortgage loans were originated.
 
THE RATE OF PREPAYMENT ON THE MORTGAGE LOANS AND THE MOVEMENT OF ONE-MONTH LIBOR
IN RELATION TO THE LOAN RATES ON THE MORTGAGE LOANS MAY ADVERSELY AFFECT THE
AMOUNT OF INTEREST PAID ON THE NOTES.
 
     The calculation of the note interest rate is based primarily upon the value
of one-month LIBOR, but subject to a maximum rate based upon the weighted
average of the loan rates (net of servicing fees, other transactional expenses
and a minimum spread as described herein) of the mortgage loans. Thus, if
mortgage loans with relatively higher loan rates prepay, the maximum interest
rate on the notes will be lower than otherwise would be the case. In this
connection, it should be noted that the
 
                                      S-14
<PAGE>   15
 
loan rates on approximately 28% of the mortgage loans in existence at the
Statistical Cut-off Date (based on principal balances) are fixed for the lives
of those mortgage loans. In addition, it is highly unlikely that changes in the
weighted average of the net loan rates of the mortgage loans will move in
correlation with changes in the value of one-month LIBOR. In particular, the
adjustable rate mortgage loans in the mortgage pool adjust their interest rate
at six-month intervals based upon six-month LIBOR whereas the note interest rate
is adjusted monthly based upon one-month LIBOR as described under "Description
of the Notes" herein. In addition, most of the adjustable rate mortgage loans
have delayed adjustment dates from two to five years after the origination date
of the loan and are subject to limitations on periodic interest rate increases
and maximum and minimum interest rates over the life of the mortgage loan,
irrespective of the movement of six-month LIBOR. Consequently, interest paid on
the notes on any payment date may not equal interest that would accrue during
the related due period at the note interest rate (without giving effect to the
available funds limitation thereon imposed by the weighted average net loan
rates on the mortgage loans). Depending upon the performance of the mortgage
loans in the mortgage pool and the relationship of the movement of one-month
LIBOR (as calculated for determining the note interest rate) and six month LIBOR
(as calculated for determining interest on the adjustable rate mortgage loans),
the available funds limitation may limit increases in the note interest rate for
extended periods in a rising interest rate environment.
 
     Although supplemental interest payments paid by the note insurer under the
financial guaranty insurance policy are intended to provide noteholders with an
additional interest payment equal to the difference, if any, between the amount
of interest accrued on the notes for an interest accrual period (without giving
effect to the available funds limitation on the note interest rate) and the
amount of interest so accrued based upon the available funds limitation, there
can be no certainty that the supplemental interest payment or other available
funds with respect to any payment date will fully cover such difference.
 
PREPAYMENT OF THE MORTGAGE LOANS MAY ADVERSELY AFFECT THE YIELD TO MATURITY OF
THE NOTES.
 
     The mortgage loans may be prepaid by the related mortgagors in whole or in
part, at any time. However, approximately 82.50% of the mortgage loans by
principal balance as of the Statistical Cut-off Date require the payment of a
fee in connection with certain prepayments, which may discourage prepayments.
Conversely, most of the adjustable rate mortgage loans are likely to have higher
prepayments as they approach their first adjustment dates because borrowers may
want to avoid periodic changes to their monthly payment.
 
     The rate of prepayments of the mortgage loans cannot be predicted and may
be affected by a wide variety of general economic, social, competitive and other
factors, including state and federal income tax policies, interest rates, the
availability of alternative financing and homeowner mobility. Therefore, no
assurance can be given as to the level of prepayments that the mortgage loans
will experience.
 
     The average life of the notes, and, if purchased at other than par, the
yields realized by noteholders will be sensitive to levels of payment, including
prepayments, on the mortgage loans. In general, the yield on notes purchased at
a premium from the outstanding principal amount thereof will be adversely
affected by a higher than anticipated level of prepayments and enhanced by a
lower than anticipated level. Conversely, the yield on notes purchased at a
discount from the outstanding principal amount thereof will be enhanced by a
higher than anticipated level of prepayments and adversely affected by a lower
than anticipated level.
 
                                      S-15
<PAGE>   16
 
THE INSURANCE POLICY DOES NOT APPLY TO PREPAYMENT RISK.
 
     In general, the protection afforded by the insurance policy is protection
for credit risk and not for prepayment risk. A claim cannot be made under the
insurance policy in an attempt to guarantee or insure that any particular rate
of prepayment is experienced by the assets in the trust.
 
PAYMENTS OF EXCESS CASH MAY AFFECT THE YIELD TO MATURITY ON THE NOTES.
 
     Excess cash will be paid to reduce the outstanding principal balance of the
notes on any payment date if the level of overcollateralization required at the
time in question exceeds the actual level of overcollateralization on such
payment date. The rate at which excess cash is paid to noteholders will affect
the yield to maturity on a note, if purchased at a premium or a discount. If the
actual rate of such excess cash payments is slower than the rate anticipated by
an investor who purchases a note at a discount, the actual yield to such
investor will be lower than the investor's anticipated yield. If the actual rate
of excess cash payments is faster than the rate anticipated by an investor who
purchases a note at a premium, the actual yield to such investor will be lower
than such investor's anticipated yield.
 
     The amount of excess cash on any payment date depends on the actual amount
of interest collected on the mortgage loans during the related collection
period. Collections of interest on the mortgage loans will be influenced by
changes in the weighted average of the loan rates on the mortgage loans
resulting from prepayments and liquidations of such mortgage loans as well as
from adjustments of loan rates on the adjustable rate mortgage loans included in
the trust. The amount of excess cash payments paid to reduce the note balance on
each payment date will be based on the level of overcollateralization required
at the time in question. The required level of overcollateralization may
increase or decrease over time. Any increase may result in an accelerated
amortization of the notes until the required level is reached. Any decrease will
result in slower amortization of the notes until the required level is reached.
 
THE ISSUER'S EXERCISE OF ITS OPTION TO REDEEM THE NOTES MAY ADVERSELY AFFECT THE
YIELD TO MATURITY OF THE NOTES.
 
     Investors in the notes should also consider what effect the issuer's option
to redeem the notes may have on such investor's anticipated yield to maturity of
the notes. Because the issuer's option to redeem the notes will become
exercisable when a substantial portion of the principal amount of the notes will
be outstanding, the issuer's decision whether or not to redeem the notes may
have a significant impact on a noteholder's yield. The issuer's decision whether
or not to redeem the notes will depend upon a number of factors at the time the
notes first become redeemable and thereafter, which factors are impossible to
predict at the time of issuance of the notes.
 
THE TRUST ASSETS ARE THE ONLY SOURCE OF PAYMENTS ON THE NOTES.
 
     The notes will be non-recourse obligations solely of the issuer and will
not represent an obligation of or interest in Financial Security Assurance Inc.,
Advanta Mortgage Corp. USA, Norwest Bank Minnesota, National Association,
Wilmington Trust Company, Bear Stearns Asset Backed Securities, Inc., American
Residential Eagle, Inc. or American Residential Investment Trust, Inc. or any of
their respective affiliates, except as described herein. The assets included in
the trust and the payments under the insurance policy will be the sole source of
payments on the notes, and there will be no recourse to Financial Security
Assurance, Inc. (other than as provided in the financial guaranty insurance
policy), Advanta Mortgage Corp. USA, Norwest Bank Minnesota, National
Association, Wilmington Trust Company, Bear Stearns Asset Backed Securities,
Inc., American Residential Eagle, Inc. or American Residential Investment Trust,
Inc. or any of their
 
                                      S-16
<PAGE>   17
 
respective affiliates, or any other entity, in the event that such assets or
payments are insufficient or otherwise unavailable to make all payments provided
for under the notes.
 
THE GEOGRAPHIC CONCENTRATION OF MORTGAGED PROPERTIES MAY RESULT IN HIGHER LOSSES
IN PARTICULAR REGIONS EXPERIENCING ECONOMIC DOWNTURNS.
 
     Approximately 36.95% of the mortgage loans by principal balance as of the
Statistical Cut-off Date are secured by mortgaged properties located in
California. In general, declines in the residential real estate market in
California may adversely affect the values of the mortgaged properties securing
such mortgage loans such that the aggregate principal balance of such mortgage
loans will equal or exceed the value of such mortgaged properties. In addition,
adverse economic conditions in California (which may or may not affect real
property values) may affect the timely payment by borrowers of scheduled
payments of principal and interest on such mortgage loans and, accordingly, the
actual rates of delinquencies, foreclosures and losses on such mortgage loans
could be higher than those currently experienced in the mortgage lending
industry in general. Mortgaged properties located in California may also be more
susceptible to certain types of hazards, such as wildfires and mudslides, and
certain types of special hazards not covered by insurance, such as earthquakes,
than properties located in other parts of the country.
 
BALLOON LOANS PRESENT SPECIAL PAYMENT RISKS.
 
     Balloon loans pose a special payment risk because the borrower must pay a
large lump sum payment of principal at the end of the loan term. If the borrower
is unable to pay the lump sum or refinance such amount, you will suffer a loss
if the collateral for such loan is insufficient, the other forms of credit
enhancement are insufficient to cover the loss and the insurer fails to perform
its obligations under the insurance policy. Approximately 12.52% of the mortgage
loans (by aggregate principal balance as of the Statistical Cut-off Date) are
balloon loans.
 
THERE MAY BE DELAYS IN RECEIPT OF LIQUIDATION PROCEEDS OR LIQUIDATION PROCEEDS
MAY BE LESS THAN THE RELATED MORTGAGE LOAN BALANCE.
 
     Substantial delays may be encountered in connection with the liquidation of
delinquent mortgage loans. Further, liquidation expenses such as legal fees,
real estate taxes and maintenance and preservation expenses may reduce the
portion of liquidation proceeds payable to you. If a mortgaged property is
liquidated for an amount that is less than the balance of the mortgage loan and
expenses associated with the liquidation and preservation of the related
mortgaged property, you will incur a loss on your investment if the note insurer
fails to perform its obligations under the insurance policy and the other form
of credit enhancements are insufficient to cover the loss.
 
THE NOTE RATING IS BASED PRIMARILY ON THE FINANCIAL STRENGTH OF THE NOTE
INSURER.
 
     The ratings on the notes depend primarily on an assessment by the rating
agencies of the mortgage loans and upon the financial strength of the note
insurer. Any reduction of the rating assigned to the financial strength of the
note insurer may cause a corresponding reduction in the ratings assigned to the
notes. A reduction in the ratings assigned to the notes will reduce the market
value of the notes and may affect your ability to sell them. In general, the
ratings on your notes address credit risk, but do not address the likelihood of
prepayments.
 
PAYMENTS TO AND RIGHTS OF INVESTORS MAY BE ADVERSELY AFFECTED BY THE INSOLVENCY
OF AMERICAN RESIDENTIAL EAGLE, INC.
 
     The sale of the mortgage loans from American Residential Eagle, Inc. to the
depositor will be treated by American Residential Eagle, Inc., the depositor and
the trust as a sale of the mortgage
 
                                      S-17
<PAGE>   18
 
loans. If American Residential Eagle, Inc. were to become insolvent, a receiver
or conservator for, or a creditor of, American Residential Eagle, Inc. may argue
that the transaction between American Residential Eagle, Inc. and the depositor
was a pledge of mortgage loans as security for a borrowing rather than a sale.
Such an attempt, even if unsuccessful, could result in delays in payments to
you.
 
CERTAIN SHORTFALLS ARE NOT COVERED BY THE SERVICER OR THE NOTE INSURER.
 
     The Master Servicer has no obligation to make advances with respect to
delinquent payments of principal on the Mortgage Loans. The Soldiers' and
Sailors' Civil Relief Act of 1940 permits certain modifications to the payment
terms for mortgage loans, including a reduction in the amount of interest paid
by the borrower, under certain circumstances. Neither the master servicer nor
the note insurer will pay for any interest shortfalls created by application of
the Soldiers' and Sailors' Civil Relief Act of 1940. In addition, the financial
guaranty insurance policy will not cover shortfalls in interest arising from
prepayments in the event that such shortfalls are not covered by the master
servicer's compensatory interest payments.
 
INVESTORS MAY HAVE DIFFICULTY SELLING THEIR NOTES.
 
     The notes will not be listed on any securities exchange. As a result, if
you wish to sell your notes, you will have to find a purchaser that is willing
to purchase your notes. The underwriter intends to make a secondary market for
the notes. The underwriter will do so by offering to buy the notes from
investors that wish to sell them. However, the underwriter will not be obligated
to make offers to buy the notes and may stop making offers at any time. In
addition, the prices offered, if any, may not reflect prices that other
potential purchasers, were they to be given the opportunity, would be willing to
pay. There have been times in the past where there have been very few buyers of
asset backed securities (i.e., there has been a lack of liquidity), and there
may be such times in the future. As a result, you may not be able to sell your
notes when you wish to do so or you may not be able to obtain the price you wish
to receive.
 
     Issuance of the notes in book-entry form may also adversely affect the
liquidity of your notes in the secondary trading market because investors may be
unwilling to purchase notes for which they cannot obtain physical certificates.
Because transactions in the notes can only be effected through the Depository
Trust Company, Cedelbank, the Euroclear system, participating organizations,
indirect participants and certain banks, the ability of an investor having a
beneficial interest in the notes to pledge such note to persons or entities that
do not participate in the Depository Trust Company, Cedelbank or Euroclear
system, or otherwise to take actions in respect of such note, may be limited due
to a lack of a physical certificate representing such note.
 
     Beneficial owners of book-entry notes may also experience some delay in
their receipt of payments of interest of and principal on the notes because such
payments will be forwarded by the indenture trustee to the Depository Trust
Company and the Depository Trust Company will credit such payments to the
accounts of its participants, which will thereafter credit them to the accounts
of beneficial owners either directly or indirectly through indirect
participants.
 
YOU WILL BEAR ALL REINVESTMENT RISK.
 
     Asset backed securities, like the notes, usually produce more returns of
principal to investors when market interest rates fall below the interest rates
on the mortgage loans and produce less returns of principal when market interest
rates are above the interest rates on the mortgage loans. As a result, you are
likely to receive more money to reinvest at a time when other investments
generally are producing a lower yield than that on the notes, and are likely to
receive less money to reinvest when other investments generally are producing a
higher yield than that on the notes. You will bear
 
                                      S-18
<PAGE>   19
 
the risk that the timing and amount of distributions on your notes will prevent
you from attaining your desired yield.
 
YEAR 2000 ISSUE MAY ADVERSELY AFFECT THE DISTRIBUTIONS TO NOTEHOLDERS.
 
     As is the case with most companies using computers in their operations,
each of the master servicer, the indenture trustee, the note insurer and The
Depository Trust Company is faced with the task of completing its compliance
goals in connection with the year 2000 issue. The year 2000 issue is the result
of prior computer programs being written using two digits, rather than four
digits, to define the applicable year. Any of these parties' computer programs
that have time-sensitive software may recognize a date using "00" as the year
1900 rather than the year 2000. Any such occurrence could result in major
computer system failure or miscalculations. Each of these parties is expected to
be engaged in various procedures to ensure that its computer systems and
software will be year 2000 compliant. However, in the event that the master
servicer, the indenture trustee, the note insurer, The Depository Trust Company
or any of their suppliers, customers, brokers or agents do not successfully
achieve year 2000 compliance on a timely basis, the performance of their
obligations under the basic documents described herein could be materially
adversely affected.
 
                          OVERVIEW OF THE TRANSACTION
 
     American Residential Eagle Bond Trust 1999-1 (the "Trust" or the "Issuer")
is a Delaware statutory business trust created pursuant to an owner trust
agreement (the "Trust Agreement"), dated as of April 1, 1999, by and between
Bear Stearns Asset Back Securities, Inc., a Delaware corporation and wholly
owned special purpose subsidiary of The Bear Stearns Companies Inc. (the
"Depositor"), and Wilmington Trust Company, a Delaware banking corporation (the
"Owner Trustee"). The primary asset of the Trust will consist of a pool (the
"Mortgage Pool") of fixed and adjustable rate mortgage loans (the "Mortgage
Loans") with original terms to maturity of not more than 30 years, secured by
first liens on one-to four-family residential properties (the "Mortgaged
Properties"). See "The Mortgage Pool".
 
     All of the Mortgage Loans were initially acquired by American Residential
Investment Trust, Inc. ("AmREIT" or the "Initial Seller") in the ordinary course
of business directly from various banks, savings and loans associations,
mortgage brokers and other mortgage lending institutions (collectively, the
"Originators") or in the secondary market. See "Underwriting Guidelines".
 
     Pursuant to a Mortgage Loan Purchase Agreement (the "Initial Mortgage Loan
Purchase Agreement"), dated as of April 1, 1999, the Initial Seller will sell
the Mortgage Loans to its wholly owned subsidiary, American Residential Eagle,
Inc., a Delaware corporation (the "Seller"). On the issuance date of the notes
(the "Closing Date") or one day prior thereto, the Seller will enter into a
second Mortgage Loan Purchase Agreement, dated as of April 1, 1999 (the
"Mortgage Loan Purchase Agreement" and, together with the Initial Mortgage Loan
Purchase Agreement, the "Sale Agreements"), with the Depositor, pursuant to
which the Seller will convey to the Depositor, without recourse, all of the
seller's right, title and interest in the Mortgage Loans, together with all
principal and interest collections on or with respect to the Mortgage Loans
received on or after April 1, 1999 (the "Cut-off Date"), exclusive of principal
and interest due prior to the Cut-off Date.
 
     Under the Mortgage Loan Purchase Agreement, the Seller will make certain
representations, warranties and covenants to the Depositor relating to, among
other things, the due execution and enforceability of the Mortgage Loan Purchase
Agreement and certain characteristics of the Mortgage Loans and, subject to
certain limitations described below under "Description of the Notes --
Assignment of the Mortgage Loans", the Initial Seller will be obligated to
purchase or substitute a similar mortgage for any Mortgage Loan as to which
there exists deficient documentation or an
 
                                      S-19
<PAGE>   20
 
uncured material breach of any such representation, warranty or covenant.
Pursuant to the Trust Agreement, on the Closing Date, the Depositor will, in
turn, assign all of its right, title and interest in the Mortgage Loans and
under the Sale Agreements to the Issuer in consideration of the Issuer's
issuance to the order of the Depositor of the Issuer's Mortgage-Backed LIBOR
Notes, Class A, Series 1999-1 (the "Notes") and a Trust Certificate (the
"Investor Certificate") representing an equity ownership interest in the assets
of the Trust. See "Descriptions of the Notes -- Assignment of the Mortgage
Loans".
 
     The Notes will be issued pursuant to an Indenture (the "Indenture"), dated
as of April 1, 1999, by and between the Issuer and Norwest Bank Minnesota,
National Association, as indenture trustee (the "Indenture Trustee"). Pursuant
to the Indenture, on the Closing Date, the Issuer will pledge, transfer and
assign without recourse to the Indenture Trustee, in trust for the benefit of
the holders of the notes (the "Noteholders"), all right, title and interest of
the Issuer in and to the Mortgage Loans (including collections received on or
with respect to the Mortgage Loans on or after the Cut-off Date but excluding
prepayment charges), all of its rights under the Sale Agreements (including the
Initial Seller's and the Seller's repurchase or substitution obligations as
described above) and all other assets pledged as collateral under the Indenture
as security for the payment of the Notes (collectively, the "Trust Estate").
AmREIT will perform certain administrative and ministerial duties required under
the Master Servicing Agreement with respect to the Mortgage Loans and under the
Indenture with respect to the Notes on behalf of the Issuer pursuant to a
Management Agreement, dated as of April 1, 1999 (the "Management Agreement"),
between AmREIT and the Issuer.
 
     Advanta Mortgage Corp. USA, a Delaware corporation (the "Master Servicer"),
will be responsible for performing all servicing obligations with respect to the
Mortgage Loans, including, but not limited to, all collection, reporting and
advancing obligations, pursuant to a Master Servicing Agreement (the "Master
Servicing Agreement"), dated of April 1, 1999, by and among the Master Servicer,
the Issuer and the Indenture Trustee. See "Servicing of the Mortgage Loans"
herein.
 
     The Depositor will enter into an underwriting agreement (the "Underwriting
Agreement") with Bear, Stearns & Co. Inc., as sole underwriter (the
"Underwriter"), with respect to the offering and sale of the Notes. See
"Underwriting" herein. In connection with such Underwriting Agreement, the
Initial Seller and the Seller will indemnify the Depositor and the Underwriter
against certain civil liabilities, including liabilities under the Securities
Act of 1933, as amended (the "1933 Act"), under a separate indemnification
agreement ( the "Indemnification and Contribution Agreement") among the Initial
Seller, the Seller, the Depositor and the Underwriter.
 
     It is a condition of issuance of the Notes that they receive a rating of
"AAA" from Standard & Poor's, a division of The McGraw-Hill Companies, Inc.
("S&P"), and a rating of "Aaa" from Moody's Investors Service, Inc. ("Moody's"
and, together with S&P, the "Rating Agencies"). See "Ratings" herein.
 
     The Depositor will apply the net proceeds received from the sale of the
Notes by the Underwriter, together with the Investor Certificate, as payment to
the Seller of the purchase price of the Mortgage Loans under the Mortgage Loan
Purchase Agreement. The Seller will pay the cash proceeds from the sale of the
Notes to the Initial Seller as part of the purchase price of the Mortgage Loans.
The Seller will retain the Investor Certificate.
 
     The Notes will have the benefit of an irrevocable and unconditional
financial guaranty insurance policy (the "Insurance Policy") issued by Financial
Security Assurance Inc., a New York stock insurance company (the "Note
Insurer"). See "The Insurance Policy" and "The Note Insurer" herein.

                               THE MORTGAGE POOL
 
GENERAL
 
     The following is a summary description of certain characteristics of the
Mortgage Loans in the Mortgage Pool as of the Statistical Cut-off Date.
 
     The information presented herein does not take into account any Mortgage
Loans which have or may prepay in full or have or may be removed because of
incomplete documentation or otherwise for the period from the Statistical
Cut-off Date to the Closing Date or other Mortgage Loans that may be substituted
therefor. In addition, such information does not reflect an additional 50
Mortgage Loans having an aggregate principal balance of approximately $6,830,924
as of the Cut-off Date, which are expected to be added to the Mortgage Pool on
the Closing Date. AS A RESULT, THE INFORMATION REGARDING THE MORTGAGE LOANS SET
FORTH HEREIN MAY VARY FROM COMPARABLE INFORMATION BASED UPON THE ACTUAL
COMPOSITION OF THE MORTGAGE POOL AT THE CLOSING DATE, ALTHOUGH SUCH VARIANCE
WILL NOT BE MATERIAL. The final composition of the Mortgage Pool will be filed
as an exhibit to the final form of Basic Documents filed on Form 8-K with the
Commission following the Closing Date.
 
     WHENEVER REFERENCE IS MADE HEREIN TO A PERCENTAGE OF SOME OR ALL OF THE
MORTGAGE LOANS, UNLESS OTHERWISE SPECIFIED, SUCH PERCENTAGE IS DETERMINED ON THE
BASIS OF THE AGGREGATE PRINCIPAL BALANCE OF THE MORTGAGE LOANS AS OF THE
STATISTICAL CUT-OFF DATE (THE "STATISTICAL CUT-OFF DATE PRINCIPAL BALANCE").
 
     The Mortgage Pool will consist, in the aggregate, of approximately 2,005
adjustable and fixed-rate Mortgage Loans with a Statistical Cut-off Date
Principal Balance of approximately $233,114,644. All of the Mortgage Loans are
secured by first liens on residential real property.
 
     Approximately 705 of the Mortgage Loans having an aggregate Principal
Balance as of the Statistical Cut-off Date of approximately $65,325,812 bear
interest rates (the "Loan Rate") which are fixed for the lives of such Loans
("Fixed Rate Mortgage Loans"). Approximately 87.48% of the Fixed Rate Mortgage
Loans are fully amortizing loans over their original term to maturity, while
12.52% have an amortization term that exceeds the original term to maturity (15
years) of such Mortgage Loans ("Balloon Loans"), leaving a substantially larger
payment ("Balloon Payments") due at maturity of such loans.
 
     Approximately 1,300 of the Mortgage Loans having an aggregate Principal
Balance as of the Statistical Cut-off Date of approximately $167,788,832 provide
for semi-annual adjustment of the applicable Loan Rate as specified in the
related Mortgage Note based on the Six-Month LIBOR Index as described herein
("Adjustable Rate Mortgage Loans") and for corresponding adjustments to the
monthly payment amount due thereon, in each case as specified in the related
Mortgage Note and subject to the limitations described under "-- Adjustable Rate
Mortgage Loans" herein. However, with respect to approximately 98.22% of such
Adjustable Rate Mortgage Loans (the "Delayed Adjustment Mortgage Loans"), the
first Loan Rate adjustment for such Mortgage Loans will occur after an initial
period ranging from two to five years as described herein. See "-- Adjustable
Rate Mortgage Loans" and "-- The Index" below.
 
     None of the Mortgage Loans will have a remaining term to maturity greater
than 360 months. In addition all of the Mortgage Loans are secured by first
mortgages or deeds of trust or similar security instruments creating first liens
on one- to four-family residential properties consisting of one-
 
                                      S-21
<PAGE>   22
 
to four-family dwelling units, individual condominium units, manufactured
housing, mixed use or individual units in planned unit developments.
 
     None of the Mortgage Loans are or will be insured or guaranteed by the
Initial Seller, the Seller, the Depositor, the Issuer, the Master Servicer, the
Indenture Trustee, the Note Insurer, any Originator, or any of their respective
affiliates or by any governmental agency or other person, except to the extent
described herein.
 
     As of the Statistical Cut-off Date, approximately 1.42% of the Mortgage
Loans were at least 30 but not more than 59 days delinquent and approximately
3.72% were 60 days or more delinquent.
 
     Approximately 30.62% of the Mortgage Loans in the Mortgage Pool had
original Loan-to-Value Ratios in excess of 80%. Substantially all such Mortgage
Loans are covered by a primary mortgage insurance policy (the "Mortgage
Insurance Policy") issued by Commonwealth Mortgage Assurance Company insuring
first on the principal balance on such Mortgage Loans. See "Primary Mortgage
Insurance Policy" herein. For this purpose the "Loan-to-Value Ratio" of a
Mortgage Loan at any time is the ratio of the principal balance of the Mortgage
Loan at the date of determination to (a) in the case of a purchase, the lesser
of the sales price of the Mortgaged Property and its appraised value at the time
of sale, or (b) in the case of a refinance or modification, the appraised value
of the Mortgaged Property at the time of such refinancing or modification.
 
     Approximately 82.50% of the Mortgage Loans provide for payment by the
mortgagor of a prepayment premium in connection with certain full or partial
prepayments of principal. Generally, each such Mortgage Loan provides for
payment of a prepayment premium in connection with certain partial prepayments
and prepayments in full made within the period of time specified in the related
Mortgage Note, ranging from one to five years from the date of origination of
such Mortgage Loan, as described herein. The amount of the applicable prepayment
premium, to the extent permitted under applicable state law, is as provided in
the related Mortgage Note; generally, such amount is equal to six months'
interest on any amounts prepaid in excess of 20% of the then original principal
balance of the related Mortgage Loan during any twelve-month period. See
"Certain Prepayment and Yield Considerations" herein.
 
     The Mortgage Loans in the Mortgage Pool are expected to have the following
approximate aggregate characteristics as of the Statistical Cut-off Date:

ADJUSTABLE RATE MORTGAGE LOANS
 
     Each Adjustable Rate Mortgage Loan provides for semi-annual adjustment of
the related Loan Rate, as specified in the related Mortgage Note, and for
corresponding adjustments to the monthly payment amount due thereon, in each
case on each adjustment date applicable thereto (each such date, an "Adjustment
Date"); provided that the first such adjustment for the Delayed Adjustment
Mortgage Loans will occur after an initial period of two years ("2/28 Loans")
following origination, in the case of approximately 82.67% of the Adjustable
Rate Mortgage Loans, three years ("3/27 loans"), in the case of approximately
2.41% of the Adjustable Rate Mortgage Loans and five years ("5/25 Loans"), in
the case of approximately 13.13% of the Adjustable Rate Mortgage Loans. On each
Adjustment Date for each Adjustable Rate Mortgage Loan, the Loan Rate thereon
will be adjusted to equal the sum, rounded generally to the nearest multiple of
0.125%, of the Index (as described below) and a fixed percentage amount (the
"Gross Margin"), provided that in the substantial majority of cases the Loan
Rate on each such Mortgage Loan generally will not increase or decrease by more
than a fixed percentage specified in the related Mortgage Note (the "Periodic
Cap") on any related Adjustment Date, except in the case of the first such
adjustment with respect to a Delayed Adjustment Mortgage Loan, and will not
exceed a specified maximum Loan Rate over the life of such Mortgage Loan (the
"Maximum Rate") or be less than a specified minimum Loan Rate over the life of
such Mortgage Loan (the "Minimum Rate"). The Loan Rate on a Delayed Adjustment
Mortgage Loan generally will not increase or decrease on the first Adjustment
Rate by more than a fixed percentage specified in the related Mortgage Note (the
"Initial Cap"); the weighted average of the Initial Caps is approximately 2.901%
per annum. Effective with the first monthly payment due on each Adjustable Rate
Mortgage Loan after each related Adjustment Date, the monthly payment amount
will be adjusted to an amount that will amortize fully the outstanding Principal
Balance of the related Mortgage Loan over its remaining term, and pay interest
at the Loan Rate as so adjusted. Due to the application of the Initial Caps,
Periodic Caps and Maximum Rates, the Loan Rate on each such Mortgage Loan, as
adjusted on any related Adjustment Date, may be less than the sum of the Index
and the related Gross Margin, rounded as described herein. The Adjustable Rate
Mortgage Loans generally do not permit the related mortgagor to convert the
adjustable Loan Rate thereon to a fixed Loan Rate. See "Certain Prepayment and
Yield Considerations" herein.
 
THE INDEX
 
     The Six-Month LIBOR Index.  The Index applicable to the determination of
the Loan Rates for the Adjustable Rate Mortgage Loans will be the average of the
interbank offered rates for six-month United States dollar deposits in the
London market, calculated as provided in the related Mortgage
 
                                      S-23
<PAGE>   24
 
Note and as most recently available either (i) as of the first business day of a
specified period of time prior to such Adjustment Date, (ii) as of the business
day of the month preceding the month of such Adjustment Date or (iii) the last
Business Day of the second month preceding the month in which such Adjustment
Date occurs, as specified in the related Mortgage Note.
 
     The Six-Month LIBOR Index is referred to herein as the "Index". In the
event that the Index becomes unavailable or otherwise unpublished, the Master
Servicer will select a comparable alternative index over which it has no direct
control and which is readily verifiable.

     (1) Credit grades are based on AmREIT's underwriting guidelines described
         in "--Underwriting Guidelines" herein.
 
UNDERWRITING GUIDELINES
 
     All of the Mortgage Loans have been purchased by AmREIT in the ordinary
course of business directly from the Originators or in the secondary mortgage
market substantially in accordance with AmREIT's underwriting guidelines. AmREIT
approves individual institutions as eligible Originators after an evaluation of
certain criteria, including the Originator's underwriting guidelines (relative
to AmREIT's underwriting guidelines), mortgage origination and servicing
experience and financial stability. Each Originator from which AmREIT purchased
the Mortgage Loans has represented and warranted that all Mortgage Loans
originated and/or sold by it will have been (i) underwritten in accordance with
standards consistent with those utilized by mortgage lenders generally during
the period of origination and (ii) originated by entities that satisfy the
criteria for originators of loans qualifying for treatment as "mortgage-related
securities" under the Secondary Mortgage Market Enhancement Act of 1984, as
amended.
 
     The following is a general summary of the underwriting guidelines believed
by AmREIT to be generally applied, with some variation, by each Originator;
however, such discussion is not intended to be a complete description of the
underwriting standards applied by any specific Originator.
 
     The underwriting guidelines are primarily intended to evaluate first, the
mortgagor's credit standing and repayment ability, and secondly, to evaluate the
value and adequacy of the mortgage property as collateral. On a case-by-case
basis, however, the originators may determine that, based upon compensating
factors, a prospective mortgagor not strictly qualifying under the applicable
underwriting guidelines warrants an underwriting exception. Compensating factors
may include, but are not limited to, low loan-to-value ratios, low
debt-to-income ratio, good credit history, stable employment, financial
reserves, and time in residence at the applicant's current address. A
substantial percentage of the Mortgage Loans included in the Mortgage Pool may
have qualified for origination by applying such underwriting exceptions.
 
     Under the underwriting exceptions, the Originators review and verify the
loan applicant's sources of income (except under the Stated Income Documentation
programs as described below), calculate the amount of income from all such
sources indicated on the loan application, review the credit history of the
applicant and calculate the debt-to-income ratio to determine the applicant's
ability to repay the loan, and review the mortgaged property for compliance with
the underwriting guidelines. The underwriting guidelines are applied in
accordance with a procedure that generally requires (i) an
 
                                      S-37
<PAGE>   38
 
appraisal of the mortgaged property that conforms to FNMA and FHLMC standards
and (ii) a review of such appraisal, which review may be conducted by the
Originator's staff appraiser or representative and, depending upon the original
principal balance and loan-to-value ratio of the mortgaged property, may include
a review of the original appraisal or a drive-by review appraisal of the
mortgaged property issued by an independent third-party, nationally recognized
appraisal firm. The underwriting guidelines generally permit single-family loans
with loan-to-value ratios at origination of up to 90% for the highest credit
grading category (80% under the stated income programs), depending on the
creditworthiness of the mortgagor and, in some cases, the type and use of the
property and the debt-to-income ratio. Under the underwriting guidelines, the
maximum combined loan-to-value ratio for purchase money mortgage loans may
differ from those applicable to refinancings.
 
     The Mortgage Loans were originated on the basis of loan application
packages submitted through mortgage brokerage companies or through the related
Originator's retail branches or were purchased from third parties approved by
the Originators. Loan application packages submitted through mortgage brokerage
companies, containing in each case relevant credit, property and underwriting
information on the loan request, are compiled by the applicable mortgage
brokerage company and submitted to the Originator for approval and funding. The
mortgage brokerage companies receive all or a portion of the loan origination
fee charged to the mortgagor at the time the loan is made.
 
     Each prospective borrower must complete an application that includes
information with respect to the applicant's liabilities, income (except with
respect to certain "No Documentation" mortgage loans described below) and
employment history, as well as certain other personal information. Each
Originator requires a credit report on each applicant from a credit reporting
company. The report typically contains information relating to such matters as
credit history with local and national merchants and lenders, installment debt
payments and any record of defaults, bankruptcy, repossession, suits or
judgments against the applicant.
 
     Mortgaged properties securing the mortgage loans are appraised by qualified
independent appraisers. Each appraisal includes a market data analysis based on
recent sales of comparable homes in the area and, where deemed appropriate,
replacement cost analysis based on the current cost of constructing a similar
home. Independent appraisals are reviewed by the Originator before the loan is
funded. Drive-by or desk-top reviews are generally performed on larger loan
balances, or on loans with higher loan-to-value ratios and a review or appraisal
is generally performed in connection with loan amounts over a certain
predetermined dollar amount established for each state.
 
     The underwriting guidelines are less stringent than the standards generally
applied by FNMA and the FHLMC. Mortgagors who qualify under the underwriting
guidelines generally have payment histories and debt ratios that would not
satisfy FNMA's and FHLMC's underwriting guidelines and may have credit histories
which include outstanding judgments or prior bankruptcies. The underwriting
guidelines establish the maximum permitted loan-to-value ratio for each loan
type based upon these and other risk factors. Because the underwriting
guidelines do not conform to FNMA or FHLMC guidelines, the Mortgage Loans are
likely to experience higher rates of delinquency, foreclosure and bankruptcy
than if they had been underwritten under the stricter guidelines used by FNMA
and FHLMC.
 
     The Mortgage Loans were originated consistent with and generally conform to
"Full Documentation," "Limited Documentation" or "Stated Income Documentation"
residential loan programs. Under each of such programs, the related Originator
generally reviews the applicant's source of income, calculates the amount of
income from sources indicated on the loan application or similar documentation,
reviews the credit history of the applicant, calculates the debt service-to-
income ratio to determine the applicant's ability to repay the loan, and reviews
the type and use of
 
                                      S-38
<PAGE>   39
 
the property being financed. The underwriting guidelines require that mortgage
loans be underwritten according to a standardized procedure that complies with
applicable federal and state laws and regulations and requires in cases where
the applicant has a high risk credit profile that the value of the property
being financed, as indicated by an appraisal and a review of the appraisal,
supports the outstanding loan balance. The underwriting guidelines permit one-to
four-family residential loans to have a loan-to-value ratios at origination of
generally up to 90%, depending on, among other things, the loan documentation
program, the purpose of the mortgage loan, the mortgagor's credit history, and
repayment ability, as well as the type and use of the property. With respect to
mortgage loans secured by mortgaged properties acquired by a mortgagor under a
"lease option purchase," the loan-to-value ratio of the related mortgage loan is
generally based on the appraised value at the time of origination of such
mortgage loan.
 
     Under the Full Documentation programs, applicants generally are required to
submit two written forms of verification of stable income for 24 months (or, if
certain loan-to-value ratio guidelines are met, for 12 months). Under the
Limited Documentation programs, generally one such form of verification is
required for six to 12 months, depending upon the practices of the applicable
Originator. Under Stated Income Documentation programs, generally an applicant
may be qualified based upon monthly income as stated on the mortgage loan
application if the applicant meets certain criteria. All of the foregoing
programs typically require that with respect to each applicant there be a
telephone verification of the applicant's employment. Verification of the source
of funds (if any) required to be deposited by the applicant into escrow in the
case of a purchase money loan is generally required under the Full Documentation
program guidelines; however, certain Originators waive such requirement in cases
of mortgage loans with loan-to-value ratios below a specified level. Generally,
no such verification is required under the other programs.
 
     Under the underwriting guidelines, various risk categories are used to
grade the likelihood that the mortgagor will satisfy the repayment conditions of
the mortgage loans. These categories establish the maximum permitted
loan-to-value ratio and loan amount, taking into account the occupancy status of
the mortgage property and the mortgagor's credit history and debt ratio. In
general, higher credit risk mortgage loans are graded in categories that permit
higher debt-to-income ratios and/or more (or more recent) indications of poor
credit, such as outstanding judgments or prior bankruptcies; however, the
underwriting guidelines establish lower maximum loan-to-value ratios and maximum
loan amounts for loans graded in such categories.
 
     Substantially all of the Mortgage Loans in the Mortgage Pool were made to
borrowers with credit ratings below those generally acceptable under FNMA and
FHLMC underwriting guidelines ("Sub-Prime Mortgage Loans"). The following matrix
generally describes the underwriting criteria
 
                                      S-39

employed by AmREIT in evaluating the credit quality of Sub-Prime Mortgage Loans.
Such underwriting criteria may differ from the criteria employed by the
Originators of the Mortgage Loans.

PRIMARY MORTGAGE INSURANCE POLICY
 
     Approximately 30.62% of the Mortgage Loans in the Mortgage Pool have
original Loan-to-Value Ratios in excess of 80%. Substantially all such Mortgage
Loans are covered by the Mortgage Insurance Policy issued by Commonwealth
Mortgage Assurance Company (the "MI Insurer"). The remainder of the Mortgage
Loans will not be covered by the Mortgage Insurance Policy. The Mortgage
Insurance Policy insures losses on the Principal Balance of each such Mortgage
Loan in an amount generally equal to, at the option of the MI Insurer, either
(a) the sum of (i) the Principal Balance of the Mortgage Loan, (ii) unpaid
accumulated interest due on the Mortgage Loan at the Loan Rate (for a maximum
period of two years) and (iii) the amount of certain advances (such as hazard
insurance, taxes, maintenance expenses and foreclosure costs) made by the Master
Servicer,
 
                                      S-40
<PAGE>   41
 
reduced by certain mitigating amounts collected with respect thereto
(collectively, the "Loss Amount"), in which case the MI Insurer would take title
to the Mortgaged Property, or (b) an amount equal to the product of (i) the Loss
Amount and (ii) the percentage of coverage (the "Coverage Percentage") specified
in the Mortgage Insurance Policy, in which case the Issuer would retain title to
(and the proceeds obtained in a foreclosure and sale of) the Mortgaged Property.
The Coverage Percentage specified in the Mortgage Insurance Policy will be
different for each Mortgage Loan depending upon the original Loan-to-Value Ratio
of the related Mortgage Loan (Mortgage Loans with higher Loan-to-Value Ratios
will generally have a higher Coverage Percentage and Mortgage Loans with lower
Loan-to-Value Ratios will generally have a lower Coverage Percentage). The
Mortgage Insurance Policy will remain in place for the life of the related
Mortgage Loan (provided that no MI Insurer Insolvency Event (as defined in the
Policy) has occurred and is continuing), even if the related Loan-to-Value Ratio
falls below 80%. If a MI Insurer Insolvency Event has occurred or is continuing,
the Issuer shall, at the discretion of the Note Insurer, and may in the case of
a Note Insurer Default, terminate the Mortgage Insurance Policy on any Mortgage
Loan that is not then past due.
 
     Claim payments, if any, under a Mortgage Insurance Policy will be made to
the Master Servicer, deposited in the Collection Account and treated in the same
manner as a prepayment of the related Mortgage Loan. Premiums payable on the
Mortgage Insurance Policy (the "MI Premiums") will be paid monthly by the Master
Servicer with funds withdrawn from the Collection Account with respect to the
related Mortgage Loans.
 
     The Note Insurer requires that, in the event of a downgrade in the rating
of the MI Insurer or a cumulative claims denial by the MI Insurer in an amount
greater than a specified amount, the required overcollateralization of the Notes
step up to an amount specified in the Insurance Agreement.
 
                        SERVICING OF THE MORTGAGE LOANS
 
GENERAL
 
     Advanta Mortgage Corp. USA (the "Master Servicer") will as Master Servicer
be responsible for all servicing obligations with respect to the Mortgage Loans
in accordance with the terms set forth in a Master Servicing Agreement (the
"Master Servicing Agreement"), dated as of April 1, 1999, by and among the
Master Servicer, the Issuer and the Indenture Trustee.
 
     The information set forth below concerning the Master Servicer under the
heading "Advanta" has been provided to the Depositor by the Master Servicer.
Neither the Depositor, the Issuer, the Initial Seller, the Seller, the Owner
Trustee, the Indenture Trustee, the Note Insurer, the Underwriter nor any of
their respective affiliates have made any independent investigation of such
information.
 
ADVANTA
 
     Advanta Mortgage Corp. USA ("Advanta") will act as both the primary
servicer and the Master Servicer of the Mortgage Loans pursuant to the Master
Servicing Agreement. Advanta is an indirect subsidiary of Advanta Corp., a
Delaware corporation ("Advanta Parent"), a publicly traded company based in
Spring House, Pennsylvania with assets as of December 31, 1998 in excess of $3.7
billion.
 
     Advanta Parent, through its subsidiaries (including Advanta) had managed
assets (including mortgage loans) in excess of $12.3 billion as of December 31,
1998.

<PAGE>   42
 
     (a) Recent Developments Related to Advanta Parent
 
     On January 25, 1999 Advanta Parent reported that on Friday, January 22,
1999, Fleet Financial Group, Inc. and certain of its affiliates ("Fleet") filed
a complaint (the "Complaint") against Advanta Parent and certain other
affiliates (including Advanta National Bank) relating to the transaction with
Fleet which closed on February 20, 1998 in which Advanta Parent contributed most
of its consumer credit card business to a limited liability company owned by
Fleet (the "Fleet Transaction"). The complaint centers around post-closing
adjustments and other matters relating to the Fleet Transaction.
 
     Advanta Parent believes that the lawsuit is inappropriate and without merit
and, on February 16, 1999, it filed its answer and counterclaims in which it
denies all of the substantive allegations in the Complaint and seeks damages
from Fleet. Advanta Parent does not expect this suit to have any material
adverse financial impact on its business.
 
     This Prospectus Supplement contains forward-looking statements that are
subject to certain risks and uncertainties that could cause actual results to
differ materially from those projected. The most significant among these risks
and uncertainties is the uncertainty of the legal process. Additional risks that
may affect Advanta Parent's performance are detailed in Advanta Parent's filings
with the Commission, including its most recent Annual Report on Form 10-K and
its Quarterly Reports on Form 10-Q.
 
     The ability of Advanta Parent's subsidiaries to honor their financial and
other obligations is to some extent influenced by the financial condition of
Advanta Parent. Such obligations of Advanta, insofar as they relate to the
Issuer and the Indenture Trustee with respect to the Mortgage Loans, primarily
consist of Advanta's limited advancing obligations and its obligation to service
the Mortgage Loans. To the extent that Advanta's ability to perform such
obligations is adversely affected, the Mortgage Loans may experience an
increased level of delinquencies and losses.
 
     As of December 31, 1998, Advanta and its subsidiaries were servicing
approximately 111,700 mortgage loans in the Owned and Managed Servicing
Portfolio (as defined below) representing an aggregate outstanding principal
balance of approximately $7.7 billion, and approximately 124,000 mortgage loans
in the Third-Party Servicing Portfolio (as defined below) representing an
aggregate outstanding principal balance of approximately $8.3 billion.
 
     The Notes will not represent an interest in or obligation of, nor are the
Mortgage Loans guaranteed by, Advanta or the Advanta Parent. Additional
information with respect to Advanta and Advanta Parent is available in the
various reports filed by Advanta and Advanta Parent with the Commission pursuant
to the Securities Exchange Act of 1934, as amended.
 
     (b) Collection Procedures
 
     Advanta employs a variety of collection techniques during the various
stages of delinquency. The primary purpose of all collection efforts performed
by Advanta is to bring a delinquent mortgage loan current in as short a time as
possible. Phone calls are used as the principal form of contacting a mortgagor.
Advanta utilizes a predictive dialing system for the effective management of
collection calling activity. Prior to initiating foreclosure proceedings,
Advanta makes every reasonable effort to determine the reason for the default;
whether the delinquency is a temporary or permanent condition, and the
mortgagor's attitude toward the obligation. Advanta will take action to
foreclose a mortgage only once every reasonable effort to cure the default has
been made and a projection of the ultimate gain or loss on REO sale is
determined. Foreclosures are processed in accordance with individual state
guidelines and in accordance with the provisions of the mortgage and applicable
state law.

THE MASTER SERVICING AGREEMENT
 
     The summary of certain provisions of the Master Servicing Agreement set
forth below and in other sections of this Prospectus Supplement, while complete
in material respects, do not purport to be exhaustive. For more details
regarding the terms of the Master Servicing Agreement, prospective investors in
the Notes are advised to review the Master Servicing Agreement, a copy of which
the Seller will provide (without exhibits) without charge upon written request
addressed to the Seller at 445 Marine View Avenue, Suite 230, Del Mar,
California 96214, attention: Portfolio Manager.
 
     Servicing Responsibilities.  Under the Master Servicing Agreement, Advanta
Mortgage Corp. USA is responsible for all servicing obligations with respect to
the Mortgage Loans including, but not limited to, all collection, advancing and
reporting obligations. Generally, the Master Servicer will be authorized and
empowered pursuant to the Master Servicing Agreement (i) to execute and deliver
(or procure the execution and delivery by the Indenture Trustee of) any and all
instruments of satisfaction or cancellation or of partial or full release or
discharge and all other comparable instruments with respect to the Mortgage
Loans and with respect to the Mortgaged Properties and (ii) to institute
foreclosure proceedings or obtain deeds in lieu of foreclosure so as to convert
title to any Mortgaged Property in the name of the Indenture Trustee on behalf
of the Noteholders and the Note Insurer.
 
     Payments on Mortgage Loans and Establishment of Collection Account.  The
Master Servicer shall establish and maintain one or more accounts (collectively,
the "Collection Account") at one or more institutions meeting the requirements
set forth in the Master Servicing Agreement. The Collection Account, and all
amounts deposited therein from time to time (excluding investment earnings)
shall be part of the Trust Estate. The Master Servicer will deposit into the
Collection Account not later than two Business Days after receipt, all payments
on or in respect of the Mortgage Loans received from or on behalf of mortgagors
and all proceeds of the Mortgage Loans, net of servicing fees, all other items
of servicing compensation, and reimbursable outstanding Servicing Advances and
Monthly Advances (each as defined below). On each Remittance Date (as defined
below), funds to be remitted to the Note Payment Account (as defined below) will
be remitted from the Collection Account to the Indenture Trustee for deposit
into the Note Payment Account. Notwithstanding the foregoing, payments and
collections that do not constitute Available Funds (e.g., amounts representing
interest due on Mortgage Loans in respect of any period on or prior to the Cut-
off Date, assumption fees, late payment charges, charges for checks returned for
insufficient funds, extension or other administrative charges or other amounts
received for application towards the payment of taxes, insurance premiums,
assessments and similar items) will not be required to be deposited into the
Collection Account (or, if deposited, will be permitted to be withdrawn from the
Collection Account).
 
     The Master Servicer may make withdrawals from the Collection Account only
for the following purposes: (a) to make deposits into the Note Payment Account
as described at "Description of the Notes -- Note Payment Account"; (b) to pay
itself any monthly Servicing Fees and other items of servicing compensation and
investment income on Permitted Investments, to the extent permitted by the
Master Servicing Agreement; (c) to make any Servicing Advance or Monthly Advance
to the extent permitted by the Master Servicing Agreement or to reimburse itself
for any Servicing Advance or Monthly Advance previously made to the extent
permitted by the Master Servicing Agreement; (d) to withdraw amounts that have
been deposited to the Collection Account in error, and (e) to clear and
terminate the Collection Account.
 
     Investment of Collection Account.  All or a portion of the Collection
Account may be invested and reinvested in one or more Permitted Investments (as
defined in the Master Servicing Agreement) bearing interest or sold at a
discount, at the Master Servicer's direction. The Indenture Trustee or any
affiliate thereof may be the obligor on, or manager or advisor of, any
investment in
 
                                      S-43
<PAGE>   44
 
any Collection Account which otherwise qualifies as a Permitted Investment. No
investment in the Collection Account may mature later than the Remittance Date
next succeeding the date of investment.
 
     The Indenture Trustee will not in any way be held liable by reason of any
insufficiency in the Collection Account resulting from any loss on any Permitted
Investment included therein (except to the extent the Indenture Trustee is the
obligor thereon).
 
     All income or other gain from investments in the Collection Account will be
held in the Collection Account for the benefit of the Master Servicer and will
be subject to withdrawal from time to time as permitted by the Master Servicing
Agreement. Any loss resulting from such investments will be for the account of
the Master Servicer. The Master Servicer will be required to deposit the amount
of any such loss immediately upon the realization of such loss to the extent
such loss will not be offset by other income or gain from investments in the
Collection Account and then available for such application.
 
     Monthly Advances.  In order to maintain a regular flow of scheduled
interest to Noteholders (rather than to guarantee or insure against losses), the
Master Servicing Agreement will require that, not later than the close of
business on the Remittance Date prior to each Payment Date, the Master Servicer
will remit or cause to be remitted a Monthly Advance, if necessary, to the
Indenture Trustee for deposit in the Note Payment Account to be paid on the
related Payment Date. A "Monthly Advance" will be equal to the sum of the
interest portion of the aggregate amount of monthly payments (net of the related
Master Servicing Fee) due on the Mortgage Loans during the related Due Period
but delinquent so as not to have been deposited into the Collection Account as
of the close of business on the last day before the related Remittance Date.
(The Master Servicer will have no obligation to make advances for delinquent
principal payments on the Mortgage Loans.) For purposes of determining the
amount of each Monthly Advance, Mortgage Loans as to which the related Mortgaged
Property has been acquired in foreclosure or similar action (each, an "REO
Property") will be treated as still outstanding until ultimate liquidation of
such property. The Master Servicer will not be required to make any Monthly
Advances with respect to (i) reductions in the amount of the monthly payments on
Mortgage Loans due to reductions made by a bankruptcy court in the amount of the
scheduled monthly payment or (ii) a reduction in the applicable Loan Rate by
application of the Soldiers' and Sailors' Relief Act of 1940, as amended.
 
     The Master Servicer may recover Monthly Advances, if not theretofore
recovered from the mortgagor on whose behalf such Monthly Advance was made, from
subsequent collections on the related Mortgage Loan, including Liquidation
Proceeds, Insurance Proceeds (each as defined at "Payment on the Notes" below)
(but only to the extent of such Insurance Proceeds or Liquidation Proceeds) and
such other amounts as may be collected by the Master Servicer from the mortgagor
or otherwise relating to the Mortgage Loan. To the extent the Master Servicer,
in its good faith business judgment, determines that any Monthly Advance
previously made will not be ultimately recoverable from subsequent collections,
Insurance Proceeds and Liquidation Proceeds on the related Mortgage Loans or
otherwise ("Nonrecoverable Advances"), the Master Servicer may reimburse itself
out of collections received on other Mortgage Loans.
 
     The Master Servicer will not be required to make any Monthly Advance that
it determines would be a Nonrecoverable Advance.
 
     Following a Master Servicer Event of Default (see "-- Master Servicer
Events of Default" below), unless such Monthly Advance would be a Nonrecoverable
Advance, the Indenture Trustee will be required to make any Monthly Advance with
respect to a Mortgage Loan which the Master Servicer fails in its obligations to
make to the extent provided in the Indenture. However, no party, including the
Master Servicer and the Indenture Trustee, will be required to make any Monthly
 
                                      S-44
<PAGE>   45
 
Advances with respect to reductions in the amount of the monthly payments on
Mortgage Loans due to reductions made by a bankruptcy court in the amount of the
scheduled monthly payment owed by a mortgagor or a reduction in the applicable
Loan Rate by application of the Soldiers' and Sailors' Relief Act of 1940, as
amended.
 
     Compensating Interest Payments.  With respect to each Mortgage Loan as to
which a prepayment in whole or in part was received, the Master Servicer will be
required with respect to such Payment Date to remit to the Indenture Trustee no
later than the related Remittance Date, from amounts otherwise payable to the
Master Servicer as the Master Servicing Fee for the related Payment Date, an
amount equal to the excess, if any, of (a) 30 days' interest on the Principal
Balance of each such Mortgage Loan (immediately prior to such payment) at the
related Loan Rate (less the related Master Servicing Fee Rate), less (b) the
amount of interest actually received on such Mortgage Loan during the related
Due Period (each such amount, a "Compensating Interest Payment") for payment on
the Notes on such Payment Date. The Master Servicer will not be entitled to be
reimbursed from collections on the Mortgage Loans or any assets of the Trust
Estate for any Compensating Interest Payments made.
 
     Realization upon Defaulted Mortgage Loans.  The Master Servicing Agreement
requires the Master Servicer, acting as the agent of the Indenture Trustee, to
foreclose upon or otherwise comparably convert to ownership in the name of the
Indenture Trustee, on behalf of the Noteholders and the Note Insurer, Mortgage
Properties securing such of the Mortgage Loans as come into default, as to which
no satisfactory arrangements can be made for the collection of delinquent
payments and which the Seller has not reacquired pursuant to the option
described below; provided, however, that if the Master Servicer has actual
knowledge or reasonably believes that any Mortgaged Property is contaminated by
hazardous or toxic wastes or substances, the Master Servicer will cause an
environmental inspection of the Mortgaged Property in accordance with accepted
servicing practices. If the environmental inspection reveals any potentially
hazardous substances, the Master Servicer will notify the Indenture Trustee and
the Note Insurer, and the Master Servicer will not foreclose or accept a deed in
lieu of foreclosure on the Mortgaged Property without the consent of the Note
Insurer. In connection with such foreclosure or other conversion, the Master
Servicer will follow such practices as it deems necessary or advisable and as
are in keeping with accepted servicing practices; provided, however, that the
Master Servicer will not be required to expend its own funds in connection with
foreclosure or other conversion, correction of a default on a senior deed of
trust or restoration of any Mortgaged Property unless the Master Servicer
determines that such foreclosure, correction or restoration will be recoverable
from the Mortgaged Property.
 
     In servicing the Mortgage Loans, the Master Servicer will be required to
determine, with respect to each defaulted Mortgage Loan, when it has recovered,
whether through trustee's sale, foreclosure sale or otherwise, all amounts, if
any, it expects to recover from or on account of such defaulted Mortgage Loan,
whereupon such Mortgage Loan will be charged off and will become a "Liquidated
Mortgage Loan."
 
     Under the Indenture, the Issuer will have the right but not the obligation,
to purchase a Mortgage Loan and thereby remove it from the lien of the Indenture
any Mortgage Loan which becomes delinquent, in whole or in part, as to three
consecutive monthly installments or any Mortgage Loan as to which enforcement
proceedings have been brought by the Master Servicer; provided, however, the
Issuer's repurchase rights (i) must first be exercised as to those Mortgage
Loans most delinquent in payment at the time of repurchase and (ii) may be
exercised, in aggregate (but excluding those Mortgage Loans being removed to
satisfy the MI Insurer's right to purchase delinquent Mortgage Loans covered by
the Mortgage Insurance Policy), with respect to no more than 3% of the Cut-off
Date Balance of the Mortgage Loans without the Note Insurer's prior consent. Any
such Mortgage Loan so reacquired will be withdrawn from the Mortgage Pool on a
Remittance Date
 
                                      S-45
<PAGE>   46
 
at the Purchase Price therefor. See "Descriptions of the Notes -- Assignment of
the Mortgage Loans".
 
     Evidence as to Compliance.  The Master Servicing Agreement provides that on
or before a specified date in each year, a firm of independent public
accountants will furnish a report to the Indenture Trustee, the Rating Agencies
and the Note Insurer to the effect that on the basis of certain procedures
substantially in conformance with the Uniform Single Attestation Program for
Mortgage Bankers ("USAP") or Statement of Auditing Standards No. 70 ("SAS 70")
(to the extent such procedures are applicable to the servicing obligations set
forth in the Master Servicing Agreement), the servicing by or on behalf of the
Master Servicer of mortgage loans, and such procedures have disclosed no
exceptions or errors in records relating to the mortgage loans serviced by the
Master Servicer for others which, in the opinion of such firm, such firm is
required to report under USAP, except for such exceptions as will be referred to
in the report. The Master Servicing Agreement will provide that the Master
Servicer will be required to deliver to the Indenture Trustee, the Rating
Agencies and the Note Insurer, on or before a specified date in each year, an
annual statement signed by an officer of the Master Servicer to the effect that
the Master Servicer has fulfilled its material obligations under the Master
Servicing Agreement throughout the preceding year.
 
     Certain Matters Regarding Master Servicer's Servicing Obligations.  The
Master Servicing Agreement will provide that the Master Servicer may not resign
from its obligations and duties as the Master Servicer thereunder, except upon
the delivery, at the Master Servicer's expense, of an opinion of counsel
addressed to the Issuer, the Indenture Trustee and the Note Insurer and in form
and substance acceptable to the Indenture Trustee and the Note Insurer, to the
effect that its duties thereunder are no longer permissible under applicable law
or regulation or are in material conflict by reason of applicable law or
regulation with any other of its activities carried on as of the date of the
Master Servicing Agreement. No such resignation will become effective until the
Indenture Trustee or a successor servicer approved by the Note Insurer has
assumed the servicing obligations and duties of the Master Servicer under the
Master Servicing Agreement.
 
     Pursuant to the Master Servicing Agreement, with the consent of both the
Note Insurer and the Indenture Trustee, the Issuer may at any time terminate the
Master Servicer without cause upon sixty days prior written notice to the Master
Servicer. If the Issuer exercises this termination right, the Initial Seller
will be required to pay the Master Servicer a termination fee as specified in
the Master Servicing Agreement. As a condition to obtaining the Note Insurer's
and Indenture Trustee's consent to such termination, the Initial Seller will
have the obligation to arrange for the appointment of a successor Master
Servicer acceptable to the Note Insurer and the Indenture Trustee.
 
     The Master Servicing Agreement will also provide that neither the Master
Servicer, nor any of its directors, officer, employees or agents, will be liable
to the Indenture Trustee, the Trust or the Noteholders for any action taken or
for refraining from the taking of any action by the Master Servicer pursuant to
the Master Servicing Agreement, or for errors in judgment; provided, however,
that neither the Master Servicer nor any such person will be protected against
any liability which would otherwise be imposed by reason of willful misfeasance,
bad faith or negligence in the performance of duties of the Master Servicer, or
by reason of reckless disregard of its duties thereunder. The Master Servicer is
required to obtain and thereafter maintain in effect a bond, corporate guaranty
or similar form of insurance coverage (which may provide relevant coverage), or
any combination thereof, insuring against loss occasioned by the errors and
omissions of its officers and employees.
 
     In addition, the Master Servicing Agreement will provide that the Master
Servicer will not be under any obligation to appear in, prosecute or defend any
legal action which is not incidental to its duties to service the Mortgage Loans
under the Master Servicing Agreement and which in its opinion
 
                                      S-46
<PAGE>   47
 
may involve it in any expense or liability. The Master Servicer will be
indemnified by the Trust for certain losses and other events to the extent
described in the Master Servicing Agreement.
 
     The Master Servicing Agreement will provide that any corporation or other
entity (a) into which the Master Servicer may be merged or consolidated, (b)
that may result from any merger, conversion or consolidation to which the Master
Servicer shall be a party, or (c) that may succeed to all or substantially all
of the business of the Master Servicer, will be the successor to the Master
Servicer thereunder without the execution or filing of any document or any
further act by any of the parties to the Master Servicing Agreement; provided,
however, that (i) the surviving entity shall be qualified to act as Master
Servicer, (ii) shall have a net worth of not less than $15,000,000 and (iii) the
Note Insurer shall have consented to its assumption of such servicing
obligations.
 
     Master Servicer Events of Default.  Events of default (each, a "Master
Servicer Event of Default") under the Master Servicing Agreement will include
(a) any failure by the Master Servicer to make a required Monthly Advance on the
related Remittance Date as required or any failure by the Master Servicer to
deposit into the Collection Account or Note Payment Account any other amount
required to be so deposited under the Master Servicing Agreement which continues
for three consecutive Business Days or results in a claim being made on the
Policy; (b) any failure by the Master Servicer duly to observe or perform in any
material respect any other of its covenants or agreements in the Master
Servicing Agreement, or any failure of a representation or warranty made by the
Master Servicer to be true and correct, which materially and adversely affects
the rights of Noteholders or the Note Insurer and continues unremedied for the
applicable cure period, if any, after the giving of written notice of such
failure to the Master Servicer by the Indenture Trustee, at the direction of the
Note Insurer, or by the Note Insurer or, with the consent of the Note Insurer,
the Noteholders holding Voting Interests aggregating not less than 51%; (c)
certain events of insolvency, readjustment of debt, marshaling of assets and
liabilities or similar proceedings regarding the Master Servicer and certain
actions by the Master Servicer indicating its insolvency or inability to pay its
obligations; (d) the occurrence of delinquencies and/or losses in respect of the
Mortgage Loans in excess of a level, and for a period of time, as specified in
the Master Servicing Agreement; and (e) the occurrence of a default under the
Insurance Agreement (which includes certain performance tests and triggers
relating to rates of delinquency and loss).
 
     Rights Upon Master Servicer Events of Default.  Upon the occurrence of a
Master Servicer Event of Default, the Note Insurer or, with the consent of the
Note Insurer, Noteholders evidencing Voting Interests represented by all Notes
aggregating not less than 51% or the Indenture Trustee, at the direction of the
Note Insurer, may terminate all of the rights and obligations of the Master
Servicer under the Master Servicing Agreement, whereupon, unless the Note
Insurer directs the Indenture Trustee to appoint another successor Master
Servicer, the Indenture Trustee will be obligated to appoint a successor Master
Servicer or, if it does not, succeed to all the responsibilities, duties and
liabilities of the Master Servicer under the Master Servicing Agreement. Any
such successor Master Servicer shall be entitled to such compensation as shall
be mutually agreed to by the Note Insurer and such successor Master Servicer at
the time of such succession. In the event that the Note Insurer fails to appoint
a successor Master Servicer and the Indenture Trustee is legally unable to act
as Master Servicer, it may petition a court of competent jurisdiction for the
appointment of a successor Master Servicer. Any such successor Master Servicer
must be an institution that regularly services residential mortgage loans, that
is an approved seller/servicer in good standing with Fannie Mae and Freddie Mac,
that has all licenses, permits and approvals required by applicable law and a
net worth of at least $15,000,000. The appointment of any such successor Master
Servicer (other than the Indenture Trustee) must be acceptable to the Note
Insurer and may not result in the qualification, reduction or withdrawal of the
implied rating assigned to the Notes by the Rating Agencies (without taking into
account the Insurance Policy). Pending appointment of a successor Master
Servicer, unless the Indenture Trustee is prohibited by law from
 
                                      S-47
<PAGE>   48
 
so acting, the Indenture Trustee shall be obligated to act as Master Servicer
(although there will be a period of transition (generally not exceeding 90 days)
before the servicing transfer can be fully effected). The Note Insurer and such
successor Master Servicer may agree upon the servicing compensation to be paid.
 
     No Noteholder, solely by virtue of its status as a Noteholder, will have
any right under the Indenture to institute any action, suit or proceeding with
respect to the Master Servicing Agreement unless the Note Insurer shall have
consented thereto.
 
     Amendments.  The Master Servicing Agreement may not be amended, changed,
modified, terminated or discharged, except by an instrument in writing signed by
all parties thereto, with the prior written consent of the Note Insurer and
subject to the provisions governing amendment in the Indenture. See "Description
of the Notes -- Amendment".
 
SERVICING AND OTHER COMPENSATION; PAYMENT OF EXPENSES
 
     The Master Servicing Fee will be the primary compensation of the Master
Servicer in respect of its servicing activities under the Master Servicing
Agreement and will be retained by the Master Servicer out of collections of
interest received on or in respect of the Mortgage Loans for the related
Collection Period. The master servicing fee (the "Master Servicing Fee") for
each Due Period will equal one-twelfth (1/12) of the product of (a) 0.50% (the
"Master Servicing Fee Rate") and (b) the aggregate Principal Balance (as defined
at "Description of the Notes -- Payment on the Notes" below) of the Mortgage
Loans as of the first day of the related Due Period. The Master Servicer shall
be entitled to retain the Master Servicing Fee from amounts to be deposited in
the Collection Account. In addition, the Master Servicer will retain the
benefit, if any, from any deposit, maintenance or investment of funds in the
Collection Account. Assumption fees, late payment charges, charges for checks
returned for insufficient funds, and extension and other administrative charges,
to the extent collected from mortgagors, will be retained by the Master Servicer
as additional servicing compensation.
 
     Subject to its right to refuse to make Nonrecoverable Advances as described
below, the Master Servicer will be required to pay all reasonable and customary
"out-of-pocket" costs and expenses incurred in the performance of its servicing
obligations, including, but not limited to, the payment of fees for any
sub-servicer and the cost of (i) any enforcement or judicial proceedings
relating to the mortgagors, including foreclosures, and (ii) the management and
liquidation of Mortgaged Properties acquired in satisfaction of the related
Mortgage Loans. Such expenditures (each, a "Servicing Advance") may include
costs of collection efforts, reappraisals, forced placement of hazard insurance
if a borrower allows his hazard policy to lapse, legal fees in connection with
foreclosure actions, advancing delinquent property taxes and upkeep and
maintenance of the Mortgaged Property if it is acquired through foreclosure and
similar types of expenses.
 
     The Master Servicing Agreement provides that the Master Servicer may pay
all or a portion of any Servicing Advance or Monthly Advance out of amounts on
deposit in the Collection Account which are being held for payment on a
subsequent Payment Date relating to such Collection Period; any such amounts so
used are required to be replaced by the Master Servicer by deposit to the
Collection Account on or before the Remittance Date relating to such subsequent
Payment Date.
 
     The Master Servicer may recover Servicing Advances, if not theretofore
recovered from the mortgagor on whose behalf such Servicing Advance was made,
from subsequent collections on the related Mortgage Loan, including liquidation
proceeds, insurance proceeds and such other amounts as may be collected by the
Master Servicer from the mortgagor or otherwise relating to the Mortgage Loan.
To the extent the Master Servicer, in its good faith business judgment,
determines that any Servicing Advance will be or has become a Nonrecoverable
Advance, the Master Servicer may
 
                                      S-48
<PAGE>   49
 
reimburse itself for such advance from amounts relating to other Mortgage Loans
in the Collection Account. The Master Servicer will not be required to make any
Servicing Advance that it determines would be a Nonrecoverable Advance if made.
 
                                   THE TRUST
 
     American Residential Eagle Bond Trust 1999-1 is a statutory business trust
created under Delaware law pursuant to the Trust Agreement between the Depositor
and the Owner Trustee for the purpose of executing the transactions described in
this Prospectus Supplement. Upon its formation, the Trust will not engage in any
activity other than (i) acquiring, holding and managing the Mortgage Loans and
the other assets of the Trust and the proceeds therefrom, (ii) issuing the Notes
and the Investor Certificate and making payments due thereon and (iii) engaging
in other activities that are necessary to accomplish the foregoing.
 
     The assets of the Trust pledged to secure the Notes will consist of (i) the
Mortgage Pool, (ii) all payments in respect of principal and interest (but
excluding prepayment charges) on the Mortgage Loans received on or after the
Cut-off Date (other than any principal or interest payments due thereon prior to
the Cut-off Date); (iii) security interests in the Mortgaged Properties; (iv)
rights under certain primary mortgage and hazard insurance policies, if any,
covering the Mortgaged Properties; (v) the Depositor's rights under the Mortgage
Loan Purchase Agreement (which have been fully assigned to the Trust); (vi) the
Trust's rights under the Master Servicing Agreement; (vii) amounts on deposit
relating to the Mortgage Loans in the Collection Account and Note Payment
Account (as described herein); (viii) certain other ancillary or incidental
funds, rights and properties related to the foregoing; and (ix) all proceeds of
the foregoing. The Noteholders will also have the benefit of the Insurance
Policy issued by the Note Insurer. See "The Insurance Policy" herein.
 
     As described at "Description of the Notes", the assets of the Trust will be
pledged under the Indenture to the Indenture Trustee and constitute the "Trust
Estate" to secure the payment of the Notes.
 
     The Owner Trustee will make no representations as to the validity or
sufficiency of the Trust Agreement, the Notes, or of any Mortgage Loans or
related documents, and will not be accountable for the use or application by the
Master Servicer or Indenture Trustee of any funds paid to the Master Servicer or
Indenture Trustee in respect of the Notes, or the Mortgage Loans, or the
investment of any monies by the Master Servicer of monies deposited into the
Collection Account or by the Indenture Trustee of any monies deposited in the
Note Payment Account. The Owner Trustee will be required to perform only those
ministerial duties specifically required of it under the Trust Agreement.
Generally, those duties will be limited to the receipt of the various
certificates, reports or other instruments required to be furnished to the Owner
Trustee under the Trust Agreement, in which case it will only be required to
examine them to determine whether they conform to the requirements of the Trust
Agreement. The duties of the Trust to be performed with respect to the Mortgage
Loans under the Master Servicing Agreement or the Notes under the Indenture will
be performed for the Trust by the Seller as manager under the Management
Agreement.
 
     The Owner Trustee may resign at any time, in which event the Indenture
Trustee will be obligated to appoint a successor thereto acceptable to the Note
Insurer. The Indenture Trustee may also remove the Owner Trustee if it ceases to
be eligible to continue as such under the Trust Agreement or becomes legally
unable to act or becomes insolvent. Any resignation or removal of the Owner
Trustee and appointment of a successor thereto will not become effective until
acceptance of the appointment by such successor.

                            DESCRIPTION OF THE NOTES
 
INTRODUCTION
 
     The Issuer will issue a single class of its Mortgage-Backed LIBOR Notes,
Class A, Series 1999-1, pursuant to an Indenture, dated as of April 1, 1999 (the
"Indenture"), by and between the Issuer and Norwest Bank Minnesota, National
Association, as indenture trustee (the "Indenture Trustee"). Pursuant to the
Trust Agreement, the Issuer will also issue a trust certificate (an "Investor
Certificate") evidencing the beneficial ownership in the assets of the Trust,
which interest will be fully subordinate in priority to payment of the Notes.
The Investor Certificate will initially be held by the Seller. The following
summary describes certain provisions of the Indenture, the Trust Agreement and
the Master Servicing Agreement and certain other Basic Documents. Such
discussion does not purport to be complete and is subject to, and qualified in
its entirety by reference to, all of the provisions of such Basic Documents. For
more details regarding the terms of the Indenture, prospective investors in the
Notes are advised to review the Indenture. The Seller will provide a copy of the
Indenture (without exhibits), without charge, upon written request addressed to:
American Residential Eagle, Inc., 445 Marine View Avenue, Suite 100, Del Mar,
California 92014, Attention: Portfolio Manager.
 
GENERAL
 
     The Notes will be secured by the Trust Estate created by the Indenture. See
"The Trust". The Notes are non-recourse obligations of the Issuer and the
proceeds of the assets of the Trust Estate, including payments under the
Insurance Policy will be the only sources of payments on the Notes. The Notes
will not represent an interest in, or an obligation of, the Issuer, the
Depositor, the Owner Trustee, the Initial Seller, the Seller, the Master
Servicer, the Indenture Trustee, the Note Insurer, the Underwriter, any of their
respective affiliates or any other entity.
 
     As of the Closing Date, the principal amount of the Notes will equal
$229,000,000 (the "Original Note Balance"), subject to the variance described on
the front cover page hereof. The principal amount of the Notes (the "Note
Balance" on any Payment Date (as defined below) will equal the Original Note
Balance minus the aggregate of amounts actually paid as principal to the holders
as described below.
 
                                      S-50
<PAGE>   51
 
     Payments on the Notes will be made on the 25th day of each month, or if
such day is not a Business Day, on the following Business Day (each, a "Payment
Date"), commencing May 25, 1999. All payments on Notes will be made by or on
behalf of the Indenture Trustee to each registered holder of a Note (a
"Noteholder") of record on the Business Day immediately prior to such Payment
Date (the "Record Date") as indicated in the register ("Note Register")
maintained by the Indenture Trustee; provided, however, if Notes are issued in
definitive form in exchange for Book-Entry Notes, the Record Date will be the
last day of the calendar month immediately prior to the Payment Date. For
purposes of the Basic Documents, a "Business Day" is any day other than (i) a
Saturday or Sunday or (ii) a day on which banking institutions in the States of
New York, Maryland, Pennsylvania, California or the state in which the corporate
trust office of the Indenture Trustee is located are required or authorized by
law to be closed for business.
 
     The Notes will initially be issued in book-entry form ("Book-Entry Notes")
through the facilities of The Depository Trust Company ("DTC"). Accordingly,
payments on the Notes will be made by or on behalf of the Indenture Trustee to
the DTC or its nominee. Notes in definitive certificated form ("Definitive
Notes") will only be issued in exchange for Book-Entry Notes in very limited
circumstances described under "Book-Entry Registration and Definitive Notes."
Payments on Definitive Notes, if issued, generally will be made either (i) by
check mailed to the address of each Noteholder as it appears in the Note
Register or (ii) by wire transfer of immediately available funds to the account
of a Noteholder, if such Noteholder (a) is the registered holder of Definitive
Notes having an initial principal amount of $1,000,000 and (b) has provided the
Indenture Trustee with wiring instructions in writing five days prior to the
related Payment Date or has provided the Indenture Trustee with such
instructions for any previous Payment Date. A fee may be charged by the
Indenture Trustee to a Noteholder of Definitive Notes for any payment made by
wire transfer. Notwithstanding the above, the first payment in redemption of any
Definitive Note will be made only upon presentation and surrender of such
Definitive Note at the office or agency designated by the Indenture Trustee for
that purpose.
 
     The Notes will be issued in denominations of $50,000 and multiples of $1 in
excess thereof, except that one note certificate may evidence an additional
amount equal to the remaining Note Balance.
 
BOOK-ENTRY REGISTRATION AND DEFINITIVE NOTES
 
     The Notes initially will be book-entry notes (the "Book-Entry Notes").
Beneficial Owners (as defined below) will hold the Notes through DTC, in the
United States, or Cedelbank ("Cedel") or the Euroclear system ("Euroclear") in
Europe, if they are participants of such systems, or indirectly through
organizations that are participants in such systems. The Book-Entry Notes
initially will be registered in the name of Cede & Co., the nominee of DTC.
Cedel and Euroclear will hold omnibus positions on behalf of Cedel Participants
and Euroclear Participants, respectively, through customers' securities accounts
in Cedel's and Euroclear's names on the books of their respective depositaries
which in turn will hold such positions in customers' securities accounts in the
depositaries' names on the books of DTC. Citibank N.A. ("Citibank") will act as
depositary for Cedel, and Morgan Guaranty Trust Company of New York ("Morgan")
will act as depositary for Euroclear (Citibank and Morgan, in such capacities,
individually the "Relevant Depositary" and collectively, the "European
Depositaries"). Except as described below, no person acquiring a Book-Entry Note
will be entitled to receive a Definitive Note. Unless and until Definitive Notes
are issued, it is anticipated that the only "Noteholder" will be Cede & Co., as
nominee of DTC or Citibank or Morgan, as nominees of Cedel and Euroclear,
respectively. Persons acquiring a beneficial ownership interest in a Note (each,
a "Beneficial Owner") will not be Noteholders as that term is used in the
Indenture. Beneficial Owners are permitted to exercise their rights only
indirectly through DTC and its Participants (including Cedel and Euroclear).
 
                                      S-51
<PAGE>   52
 
     The beneficial ownership of a Book-Entry Note will be recorded on the
records of the brokerage firm, bank, thrift institution or other financial
intermediary (each, a "Financial Intermediary") that maintains the Beneficial
Owner's account for such purpose. In turn, the Financial Intermediary's
ownership of such Book-Entry Note will be recorded on the records of DTC (or of
a participating firm that acts as agent for the Financial Intermediary, whose
interest will in turn be recorded on the records of DTC, if the Beneficial
Owner's Financial Intermediary is not a Participant and on the records of Cedel
or Euroclear, as appropriate).
 
     Beneficial Owners will receive all payments of principal of, and interest
on, the Notes from the Indenture Trustee through DTC and its Participants
(including Cedel and Euroclear). While the Notes are outstanding (except under
the circumstances described below), under the rules, regulations and procedures
creating and affecting DTC and its operations (the "Rules"), DTC is required to
make book-entry transfers among Participants on whose behalf it acts with
respect to the Notes and is required to receive and transmit payments of
principal of, and interest on, the Notes. Participants and indirect participants
with whom Beneficial Owners have accounts with respect to Book-Entry Notes are
similarly required to make book-entry transfers and receive and transmit such
payments on behalf of their respective Beneficial Owners. Accordingly, although
Beneficial Owners will not possess certificates, the Rules provide a mechanism
by which Beneficial Owners will receive payments and will be able to transfer
their interests.
 
     Beneficial Owners will not receive or be entitled to receive certificates
representing their respective interests in the Notes, except under the limited
circumstances described below. Unless and until Definitive Notes are issued,
Beneficial Owners who are not Participants may transfer ownership of Notes only
through Participants and indirect participants by instructing such Participants
and indirect participants to transfer Notes, by book-entry transfer, through DTC
for the account of the purchasers of the Notes, which account is maintained with
their respective Participants. Under the Rules and in accordance with DTC's
normal procedures, transfers of ownership of Notes will be executed through DTC
and the accounts of the respective Participants at DTC will be debited and
credited. Similarly, the Participants and indirect participants will make debits
or credits, as the case may be, on their records on behalf of the selling and
purchasing Beneficial Owners.
 
     Because of time zone differences, credits of securities received in Cedel
or Euroclear as a result of a transaction with a Participant will be made during
subsequent securities settlement processing and dated the business day following
the DTC settlement date. Such credits or any transactions in such securities
settled during such processing will be reported to the relevant Euroclear
Participants or Cedel Participants on such business day. Cash received in Cedel
or Euroclear as a result of sales of securities by or through a Cedel
Participant or Euroclear Participant will be received with value on the DTC
settlement date but will be available in the relevant Cedel or Euroclear cash
account only as of the business day following settlement in DTC. For information
with respect to tax documentation procedures relating to the Notes, see "ANNEX
A: Global Clearance, Settlement and Tax Documentation Procedures -- Certain U.S.
Federal Income Tax Documentation Requirements" hereto.
 
     Transfers between Participants will occur in accordance with DTC Rules.
Transfers between Cedel Participants and Euroclear Participants will occur in
accordance with their respective rules and operating procedures.
 
     Cross-market transfers between persons holding directly or indirectly
through DTC, on the one hand, and directly or indirectly through Cedel
Participants or Euroclear Participants, on the other, will be effected in DTC in
accordance with DTC Rules on behalf of the relevant European international
clearing system by the Relevant Depositary; however, such cross-market
transactions will require delivery of instructions to the relevant European
international clearing system by the counterparty in such system in accordance
with its rules and procedures and within its established
 
                                      S-52
<PAGE>   53
 
deadlines (European time). The relevant European international clearing system
will, if the transaction meets its settlement requirements, deliver instructions
to the Relevant Depositary to take action to effect final settlement on its
behalf by delivering or receiving securities in DTC, and making or receiving
payment in accordance with normal procedures for same day funds settlement
applicable to DTC. Cedel Participants and Euroclear Participants may not deliver
instructions directly to the European Depositaries.
 
     DTC, which is a New York-chartered limited purpose trust company, performs
services for its participants ("Participants"), some of which (and/or their
representatives) own DTC. In accordance with its normal procedures, DTC is
expected to record the positions held by each Participant in the Book-Entry
Notes, whether held for its own account or as a nominee for another person. In
general, beneficial ownership of Book-Entry Notes will be subject to the rules,
regulations and procedures governing DTC and its Participants as in effect from
time to time.
 
     Cedel is incorporated under the laws of Luxembourg as a professional
depository. Cedel holds securities for its participating organizations ("Cedel
Participants") and facilitates the clearance and settlement of securities
transactions between Cedel Participants through electronic book-entry changes in
accounts of Cedel Participants, thereby eliminating the need for physical
movement of certificates. Transactions may be settled in Cedel in any of 28
currencies, including United States Dollars. Cedel provides to its Cedel
Participants, among other things, services for safekeeping, administration,
clearance and settlement of internationally traded securities and securities
lending and borrowing. Cedel interfaces with domestic markets in several
countries. As a professional depositary, Cedel is subject to regulation by the
Luxembourg Monetary Institute. Cedel Participants are recognized financial
institutions around the world, including underwriters, securities brokers and
dealers, banks, trust companies, clearing corporations and certain other
organizations. Indirect access to Cedel is also available to others, such as
banks, brokers, dealers and trust companies that clear through or maintain a
custodial relationship with a Cedel Participant, either directly or indirectly.
 
     Euroclear was created in 1968 to hold securities for its participants
("Euroclear Participants") and to clear and settle transactions between
Euroclear Participants, through simultaneous electronic book-entry delivery
against payment, thereby eliminating the need for physical movement of
certificates and any risk from lack of simultaneous transfers of securities and
cash. Transactions may be settled through Euroclear in any of 32 currencies,
including United States Dollars. Euroclear provides various other services,
including securities lending and borrowing, and interfaces with domestic markets
in several countries generally similar to the arrangements for cross-market
transfers with DTC described above. Euroclear is operated by the Brussels,
Belgium office of Morgan Guaranty Trust Company of New York (the "Euroclear
Operator"), under contract with Euroclear Clearance Systems S.C., a Belgian
cooperative corporation (the "Cooperative"). All operations are conducted by the
Euroclear Operator, and all Euroclear securities clearance accounts and
Euroclear cash accounts are accounts with the Euroclear Operator, not the
Cooperative. The Cooperative establishes policy for Euroclear on behalf of
Euroclear Participants. Euroclear Participants include banks (including central
banks), securities brokers and dealers and other professional financial
intermediaries. Indirect access to Euroclear is also available to other firms
that clear through or maintain a custodial relationship with a Euroclear
Participant, either directly or indirectly.
 
     The Euroclear Operator is the Belgian branch of a New York banking
corporation that is a member bank of the Federal Reserve System. As such, it is
regulated and examined by the Board of Governors of the Federal Reserve System
(the "Federal Reserve Board") and the New York State Banking Department, as well
as the Belgian Banking Commission.
 
     Securities clearance accounts and cash accounts with the Euroclear Operator
are governed by the Terms and Conditions Governing Use of Euroclear and the
related Operating Procedures of the Euroclear System and applicable Belgian law
(collectively, the "Terms and Conditions"). The Terms
 
                                      S-53
<PAGE>   54
 
and Conditions govern transfers of securities and cash within Euroclear,
withdrawals of securities and cash from Euroclear and receipts of payments with
respect to securities in Euroclear. All securities in Euroclear are held on a
fungible basis without attribution to specific securities clearance accounts.
The Euroclear Operator acts under the Terms and Conditions only on behalf of
Euroclear Participants, and has no record of or relationship with persons
holding through Euroclear Participants.
 
     Payments on the Book-Entry Notes will be made on each Payment Date by the
Indenture Trustee to DTC. DTC will be responsible for crediting the amount of
such payments to the accounts of the applicable Participants in accordance with
DTC's normal procedures. Each Participant will be responsible for disbursing
such payments to the Beneficial Owners that it represents and to each Financial
Intermediary for which it acts as agent. Each such Financial Intermediary will
be responsible for disbursing funds to the Beneficial Owners that it represents.
 
     Under a book-entry format, Beneficial Owners may experience some delay in
their receipt of payments because such payments will be forwarded by the
Indenture Trustee to Cede & Co. Payments with respect to Notes held through
Cedel or Euroclear will be credited to the cash accounts of Cedel Participants
or Euroclear Participants in accordance with the relevant system's rules and
procedures, to the extent received by the Relevant Depositary. Such payments
will be subject to tax reporting in accordance with relevant United States tax
laws and regulations. See "ANNEX A: Global Clearance, Settlement and Tax
Documentation Procedures -- Certain U.S. Federal Income Tax Documentation
Requirements" hereto. Because DTC has indicated that it will act only on behalf
of Financial Intermediaries, the ability of Beneficial Owners to pledge
Book-Entry Notes to persons or entities that do not participate in the
depository system or otherwise take actions in respect of such Book-Entry Notes
may be limited due to the lack of physical certificates representing such
Book-Entry Notes. In addition, issuance of the Book-Entry Notes in book-entry
form may reduce the liquidity of the Notes in the secondary market because
certain potential investors may be unwilling to purchase Notes for which they
cannot obtain physical certificates.
 
     The monthly and annual statements with respect to the Mortgage Loans and
the Notes as described under "-- Reports to Noteholders" herein will be provided
by the Indenture Trustee to Cede & Co., as nominee of DTC and a Noteholder, and
may be made available by such entity to Beneficial Owners upon request, in
accordance with the Rules, and to the Financial Intermediaries to whose DTC
accounts the related Book-Entry Notes are credited.
 
     DTC has advised the Indenture Trustee that, unless and until Definitive
Notes are issued, DTC will take any action permitted to be taken by a Noteholder
under the Indenture only at the direction of one or more Financial
Intermediaries to whose DTC accounts the Book-Entry Notes are credited, to the
extent that such actions are taken on behalf of Financial Intermediaries whose
holdings include such Book-Entry Notes. Cedel or the Euroclear Operator, as the
case may be, will take any other action permitted to be taken by a Noteholder
under the Indenture on behalf of a Cedel Participant or Euroclear Participant
only in accordance with its relevant rules and procedures and subject to the
ability of the Relevant Depositary to effect such actions on its behalf through
DTC. DTC may take actions, at the direction of the related Participants, with
respect to some Notes that conflict with actions taken with respect to other
Notes.
 
     Definitive Notes will be issued in registered form to Beneficial Owners, or
their nominees, rather than to DTC, only if (i) DTC or the Issuer advises the
Indenture Trustee in writing that DTC is no longer willing or able to discharge
properly its responsibilities as nominee and depositary with respect to the
Notes and the Issuer or the Indenture Trustee is unable to locate a qualified
successor, (ii) the Issuer, at its option, advises the Indenture Trustee that it
elects to terminate the book-entry system through DTC, or (iii) after a Note
Event of Default under the Indenture, the Beneficial Owners representing not
less than 51% of the aggregate Principal Balance of the Book-Entry Notes advise
the Indenture Trustee and DTC that the book-entry system is no longer in the
best interests of such
 
                                      S-54
<PAGE>   55
 
Beneficial Owners. Upon issuance of Definitive Notes to Beneficial Owners, the
Notes will be transferable directly (and not exclusively on a book-entry basis)
and registered holders will deal directly with the Indenture Trustee with
respect to transfers, notices and payments.
 
     Upon the occurrence of any of the events described in the immediately
preceding paragraph, the Indenture Trustee will be required to notify DTC, which
in turn will notify all Beneficial Owners of the occurrence of such event and
the availability through DTC of Definitive Notes. Upon surrender by DTC of the
global certificates representing the Book-Entry Notes and instructions for re-
registration, the Indenture Trustee will issue Definitive Notes and thereafter
the Indenture Trustee will recognize the holders of such Definitive Notes as
Noteholders under the Indenture.
 
     Although DTC, Cedel and Euroclear have agreed to the foregoing procedures
in order to facilitate transfer of Notes among participants of DTC, Cedel and
Euroclear, they are under no obligation to perform or continue to perform such
procedures and such procedures may be discontinued at any time.
 
     DTC management is aware that some computer applications, systems, and the
like for processing data ("Systems") that are dependent upon calendar dates,
including dates before, on, and after January 1, 2000, may encounter "Year 2000
problems." DTC has informed its Participants and other members of the financial
community (the "Industry") that it has developed and is implementing a program
so that its Systems, as the same relate to the timely payment of distributions
(including principal and income payments) to securityholders, book-entry
deliveries, and settlement of trades within DTC ("DTC Services"), continue to
function appropriately. This program includes a technical assessment and a
remediation plan, each of which is complete. Additionally, DTC's plan includes a
testing phase, which is expected to be completed within appropriate time frames.
 
     However, DTC's ability to perform properly its services is also dependent
upon other parties, including but not limited to issuers and their agents, as
well as third party vendors from whom DTC licenses software and hardware, and
third party vendors on whom DTC relies for information or the provision of
services, including telecommunication and electrical utility service providers,
among others. DTC has informed the Industry that it is contacting (and will
continue to contact) third party vendors from whom DTC acquires services to: (i)
impress upon them the importance of such services being year 2000 compliant; and
(ii) determine the extent of their efforts for Year 2000 remediation (and, as
appropriate, testing) of their services. In addition, DTC is in the process of
developing such contingency plans as it deems appropriate.
 
     According to DTC, the foregoing information with respect to DTC has been
provided to the Industry for informational purposes only and is not intended to
serve as a representation, warranty, or contract modification of any kind.
 
ASSIGNMENT OF MORTGAGE LOANS
 
     The Mortgage Loans were acquired by AmREIT from various Originators either
directly or in the secondary market and sold by AmREIT to the Seller pursuant to
the Initial Mortgage Loan Purchase Agreement. See "Overview of the Transaction"
and "Underwriting Guidelines". On or prior to the Closing Date, the Seller will
convey each Mortgage Loan to the Depositor pursuant to the Mortgage Loan
Purchase Agreement between the Seller and the Depositor and the Depositor in
turn will convey each such Mortgage Loan to the Issuer pursuant to the Trust
Agreement.
 
     At the time of issuance of the Notes, the Issuer will pledge all of its
right, title and interest in and to the Mortgage Loans, including all principal
and interest due on each such Mortgage Loan on or after the Cut-off Date (but
excluding prepayment charges) and all other Trust assets comprising the Trust
Estate, without recourse, to the Indenture Trustee pursuant to the Indenture as
collateral for the Notes; provided, however, that the Seller will reserve and
retain all its right, title and interest
 
                                      S-55
<PAGE>   56
 
in and to principal and interest due on the Mortgage Loans prior to the Cut-off
Date (whether or not received prior to such Cut-off Date), and to prepayments
received on or prior to the Cut-off Date. The Indenture Trustee, concurrently
with such assignment, will authenticate and deliver the Notes at the direction
of the Issuer in exchange for the Trust Estate.
 
     The Indenture will require the Issuer to deliver to the Indenture Trustee
or to Bankers Trust Company of California, N.A. as its custodian (the
"Custodian"), the related Mortgage Notes endorsed without recourse to the
Indenture Trustee or in blank, the related mortgages or deeds of trust with
evidence of recording thereon, if applicable, and certain other documents
relating to the Mortgage Loans (collectively, the "Mortgage Files"). The Initial
Seller will be required to cause to be prepared at the expense of the Initial
Seller and within the time period specified in the Indenture (or, if original
recording information is unavailable, within such later period as is permitted
by the Indenture), assignments of the mortgages to the Indenture Trustee.
 
     The Indenture Trustee or the Custodian on behalf of the Indenture Trustee
will review the Mortgage Files delivered to it and if any document required to
be included in any Mortgage File is found to be missing or to be defective in
any material respect and such defect is not cured within 90 days following
notification thereof to the Issuer, the Depositor, the Note Insurer and the
Seller by the Indenture Trustee or the Custodian, the Indenture Trustee will
require either that the related Mortgage Loan be removed from the Mortgage Pool
or that a Mortgage Loan conforming to the requirements of the Indenture (a
"Qualified Replacement Mortgage") be substituted for the related Mortgage Loan
in the manner described below.
 
     In connection with the transfer of the Mortgage Loans to the Depositor, the
Seller will make certain representations and warranties under the Mortgage Loan
Purchase Agreement as to the accuracy in all material respects of the
information set forth on a schedule identifying and describing each Mortgage
Loan. In addition, the Seller will make certain other representations and
warranties regarding the Mortgage Loans, including, for instance, that each
Mortgage Loan, at its origination, complied in all material respects with
applicable state and federal laws; that each mortgage is a valid first priority
lien; that, as of the Statistical Cut-off Date, no more than approximately 2.58%
of the Mortgage Loans (by Principal Balance as of the Statistical Cut-off Date)
will be more than two payments past due; that each Mortgaged Property consists
of a one- to four-family residential property, including, but not limited to,
condominiums, planned unit developments, manufactured housing or mixed use
property; that the Seller had good title to each Mortgage Loan prior to such
transfer; and that the Originator was authorized to originate each Mortgage
Loan. The rights of the Depositor to enforce remedies for breaches of such
representations and warranties in the Mortgage Loan Purchase Agreement against
the Initial Seller will be assigned by the Depositor to the Issuer (and by the
Issuer to the Indenture Trustee pursuant to the Indenture).
 
     If with respect to any Mortgage Loan (1) a defect in any document
constituting a part of the related Mortgage File remains uncured within the
period specified above and materially and adversely affects the value of any
such Mortgage Loan or materially and adversely affects the interest of the
Indenture Trustee, the Noteholders or the Note Insurer therein or (2) a breach
of any representation or warranty made by the Seller relating to such Mortgage
Loan materially and adversely affects the value of any such Mortgage Loan or
materially and adversely affects the interests of the Indenture Trustee, the
Noteholders or the Note Insurer therein, the Indenture Trustee will enforce the
remedies for such defects or breaches against the Initial Seller by requiring
the Initial Seller to remove the related Mortgage Loan (any such Mortgage Loan,
a "Defective Mortgage Loan") from the Trust Estate by remitting to the Indenture
Trustee an amount equal to the Principal Balance (as defined herein) of such
Defective Mortgage Loan together with interest accruing at the Loan Rate (net of
the applicable Servicing Fee Rate) on such Defective Mortgage Loan from the date
interest was last paid by the related mortgagor to the end of the Due Period
immediately preceding the related
 
                                      S-56
<PAGE>   57
 
Remittance Date, plus, the amount of any unreimbursed Servicing Advances made by
the Master Servicer with respect to such Defective Mortgage Loan, less any
payments received during the related Collection Period in respect of such
Defective Mortgage Loan (the "Purchase Price"). The Initial Seller will also
have the option, but not the obligation, to substitute for such Defective
Mortgage Loan a Qualified Replacement Mortgage. Upon delivery of a Qualified
Replacement Mortgage and deposit of certain amounts in the Note Payment Account
(as hereinafter defined) as set forth in the Indenture, or deposit of the
Purchase Price in the Note Payment Account and receipt by the Indenture Trustee
and the Note Insurer of written notification of any such substitution or
removal, as the case may be, the Indenture Trustee shall execute and deliver an
instrument of transfer or assignment necessary to vest legal and beneficial
ownership of such Defective Mortgage Loan (including any property acquired in
respect thereof or proceeds of any insurance policy with respect thereto) to the
Initial Seller and release such Defective Mortgage Loan from the Trust Estate.
 
     The "Collection Period" with respect to a Payment Date shall be the period
beginning on the first day of the calendar month immediately preceding the month
in which such Payment Date occurs (or, in the case of the first Payment Date,
the period beginning on the Cut-off Date) and ending on the last day of such
calendar month. The "Remittance Date" shall be the 18th day of the month, or if
such day is not a Business Day, the next succeeding Business Day). The "Due
Period" with respect to any Payment Date shall be the period commencing on the
second day of the calendar month immediately preceding the calendar month in
which such Payment Date occurs (or, with respect to the first Payment Date,
commencing on the Cut-off Date for each Mortgage Loan) and ending on the first
day of the calendar month in which such Payment Date occurs.
 
     The obligation of the Seller to cure, remove or substitute any Mortgage
Loan as described above will constitute the sole remedy available to
Noteholders, the Note Insurer (with certain exceptions) or the Indenture Trustee
for a Defective Mortgage Loan.
 
PAYMENT ON THE NOTES
 
     Priority of Payments.  Payments on the Notes will be made by the Indenture
Trustee (in such capacity, the "Paying Agent") on each Payment Date, commencing
with the Payment Date in May 1999, to Noteholders as of the Record Date in an
amount equal to the product of such Noteholders' Percentage Interest and the
amount paid in respect of the Notes. Payments on the Notes will be made solely
from Available Funds (as defined below). The "Percentage Interest" represented
by any Note will be equal to the percentage obtained by dividing the aggregate
principal balance of such Note by the Note Balance.
 
     On each Payment Date, the Paying Agent will be required to pay the
following amounts with respect to the Notes, in the following order of priority,
out of Available Funds:
 
          first, to the Noteholders, an amount equal to (a) the Monthly Interest
     Amount for such Payment Date and (b) any unpaid interest due pursuant to
     this clause first with respect to previous Payment Dates;
 
          second, to the Noteholders, an amount equal to the Monthly Principal
     Amount for the Notes with respect to such Payment Date in reduction of the
     Note Balance until the Note Balance is reduced to zero;
 
          third, to the Note Insurer, any amount due to the Note Insurer
     pursuant to the Insurance Agreement (together with interest thereon at the
     rate specified in the Insurance Agreement);
 
          fourth, to the Noteholders, the amount, if any, necessary for the
     Overcollateralization Amount to equal the Required Overcollateralization
     Amount on such Payment Date (after giving effect to application of the
     Monthly Principal Amount for such Payment Date) in reduction of the Note
     Balance until the Note Balance is reduced to zero; and
                                      S-57
<PAGE>   58
 
          fifth, to the Noteholders, the amount of any LIBOR Carryover Amount.
 
     Any Available Funds remaining after the application of priorities first
through fifth above will be released by the Indenture Trustee to the Issuer for
distribution to the holder of the Investor Certificate on such Payment Date free
from the lien of the Indenture. Once distributed, such amounts will not be
available to make payments on the Notes or payments to the Note Insurer on any
subsequent Payment Date.
 
     In the event that, with respect to a particular Payment Date, Available
Funds on such date are not sufficient to pay any portion of the Monthly Interest
Amount for the Notes (as described below), the Indenture Trustee will file a
claim on the Insurance Policy in an amount equal to such deficiency and apply
the Insured Payment in respect of such claim to the payment of the deficiency in
the Monthly Interest Amount. In addition, the Indenture Trustee will file a
claim on the Insurance Policy in an amount equal to any Overcollateralization
Deficit (as defined at "-- Overcollateralization" below) on a Payment Date
(after taking into account payments in respect of the Monthly Principal Amount
and Excess Cash on such Payment Date) and pursuant to priority fourth above
apply the portion of the Insured Payment related to such Overcollateralization
Deficit to reduce the Note Balance on such Payment Date by the amount of such
Overcollateralization Deficit. Any Insured Payment paid to make up any
Overcollateralization Deficit shall be paid to the Noteholders, in reduction of
the Note Balance, until the Note Balance is reduced to zero. The Indenture
Trustee will also file a claim on the Insurance Policy in an amount equal to the
unpaid principal balance of the Notes on the Stated Maturity Date or, if
earlier, the date on which the Trust is terminated pursuant to the Indenture.
Under the Insurance Policy, the Note Insurer will also be required to pay to the
Indenture Trustee on behalf of the Trust an amount equal to the Supplemental
Interest Payment, if any, with respect to a Payment Date, calculated as
described under "Description of the Notes -- Supplemental Interest Payments". In
the event that the Monthly Interest Amount for a Payment Date is limited by the
Net Funds Cap limitation on the Note Interest Rate (See "Description of the
Notes -- Note Interest Rate"), such Supplemental Interest Payments (if any) will
be used to pay Noteholders an additional amount of interest up to an amount
equal to the excess of (i) the Monthly Interest Amount calculated on the basis
of One-Month LIBOR plus the applicable Note Margin (but subject to the Cap Rate)
over (ii) the Monthly Interest Amount for such Payment Date calculated on the
basis of the Net Funds Cap limitation (such difference, a "Basis Risk
Shortfall"). However, the amount of the Supplemental Interest Payments for any
Payment Date may be less or more than the related Basis Risk Shortfall. If the
Supplemental Interest Payment is less than the Basis Risk Shortfall, there will
be a LIBOR Carryover Amount for such Payment Date. In the event that the
Supplemental Interest Payment exceeds the Basis Risk Shortfall for the related
Payment Date, such amount will be applied as additional Available Funds paid in
accordance with the priorities described above.
 
     In no event will the aggregate payments of principal to Noteholders exceed
the Original Note Balance.
 
     Certain Definitions. For purposes of the priorities discussed above, the
following terms have the meanings set forth below:
 
     "Available Funds" with respect to any Payment Date will consist of the sum

permitted by the Master Servicing Agreement; (iii) any unpaid Master Servicing
Fee attributable to prior periods due to the Master Servicer; (iv) any unpaid
fees and expenses and other amounts owed to the Indenture Trustee, the

     related Collection Period and applied by the Master Servicer to reduce the
     Principal Balance of the related Mortgage Loan ("Insurance Proceeds")
     (which proceeds will not include any amounts applied to the restoration or

     or substituted by the Seller during the related Collection Period as
     described in "-- Assignment of Mortgage Loans" and "Servicing of the
     Mortgage Loans" herein, to the extent such amounts are received by the
     Indenture Trustee on or before the related Remittance Date;
 
          (f) the amount of any Monthly Advances made for such Payment Date;
 
          (g) the aggregate of amounts deposited in the Note Payment Account by
     the Indenture Trustee, the Issuer or the Note Insurer, as the case may be,
     during such Collection Period in connection with redemption of the Notes as
     described under "-- Redemption of the Notes" herein; and
 
          (h) any amount of Supplemental Interest Payments for such Payment Date
     in excess of the amount necessary to cover a Basis Risk Shortfall.

basis of the Net Funds Cap, (ii) any LIBOR Carryover Amount remaining unpaid
from prior Payment Dates and (iii) interest on the amount in clause (ii)

preceding sentence.
 
     "Liquidated Mortgage Loan" means, as to any Payment Date, any Mortgage Loan

remitted by the Seller or the Master Servicer to the Indenture Trustee on the
next succeeding Remittance Date in connection with a substitution of a Qualified
Replacement Mortgage for such Mortgage Loan pursuant to the Indenture, to the
extent such amount is actually remitted on or prior to such Remittance Date;
provided, however, that Mortgage Loans that have become Liquidated Mortgage
Loans since the preceding Determination Date (or, in the case of the first

Balance of zero on the current Determination Date.
 
     "Principal Prepayment" means any mortgagor payment or other recovery in
respect of principal on a Mortgage Loan (including Net Liquidation Proceeds and
Insurance Proceeds allocable to principal) which, in the case of a mortgagor
payment, is received in advance of its scheduled due date and not accompanied by

THE NOTE INTEREST RATE
 
     The "Note Interest Rate" for any Payment Date will be a per annum rate
equal to the least of (i) the applicable Formula Rate, (ii) the applicable CAP
Rate and (iii) the Net Funds Cap. Interest in respect of any Payment Date will
accrue during the related Interest Accrual Period on the basis of a 360-day year
and the actual number of days elapsed.
 
                                      S-61
<PAGE>   62
 
     The "Formula Rate" will equal One-Month LIBOR as determined by the
Indenture Trustee as set forth under "-- Calculation of One-Month LIBOR" plus
the applicable margin (the "Note Margin") set forth below:
 
<TABLE>
<CAPTION>
NOTE MARGIN(1)   NOTE MARGIN(2)
- --------------   --------------
<S>              <C>
    0.35%            0.70%
</TABLE>
 
- ---------------
(1) Prior to the Initial Redemption Date.
 
(2) On or after the Initial Redemption Date (see "-- Redemption of the Notes"
    below).
 
     The "Cap Rate" will equal 15.00% per annum both prior to and after the
Initial Redemption Date.
 
     The "Net Funds Cap" for any Payment Date will equal the "Weighted Average
Net Loan Rate" calculated as (i) the average of the Loan Rates of the Mortgage
Loans as of the first day of the month preceding the month of such Payment Date
(or in the case of the first Payment Date, the Closing Date), weighted on the
basis of the Principal Balances of the Mortgage Loans as of such date minus(ii)
the sum of the (a) Master Servicing Fee Rate, (b) the Indenture Trustee Fee Rate
(i.e., the Indenture Trustee Fee expressed as the annual percentage of the then
Pool Principal Balance), (c) the Note Insurance Premium Rate (i.e., the Note
Insurance Premium expressed as an annual percentage of the then Note Balance),
(d) the Mortgage Insurance Premium Rate (i.e., the Mortgage Insurance Premium
expressed as an annual percentage of the then balance of the Mortgage Loans
covered by such policy), (e) the Management Fee Rate (i.e., the Management Fee
expressed as an annual percentage of the then Pool Principal Balance), and (f)
the Minimum Spread ((a) through (f) collectively, the "Aggregate Expense Rate").
The sum of the Master Servicing Fee Rate, the Indenture Trustee Fee Rate, the
Note Insurance Premium Rate, the Mortgage Insurance Premium Rate and the
Management Fee Rate will be approximately 1.025% per annum for the initial Due
Period and is subject to change based on (i) the actual rate of prepayments of
Mortgage Loans covered by the Mortgage Insurance Policy and (ii) the change in
the Minimum Spread required by the Note Insurer. The "Minimum Spread" is equal
to 0% for the first fifteen Payment Dates, 0.50% from the sixteenth Payment Date
to the sixtieth Payment Date and 0.75% thereafter.
 
     Calculation of One-Month LIBOR.  With respect to each Payment Date, Date,
One-Month LIBOR shall be established by the Indenture Trustee and will equal the
rate for one month United States dollar deposits quoted on Telerate Page 3750 as
of 11:00 A.M., London time, on the second LIBOR Business Day prior to the first
day of the relate Interest Accrual Period (or the second LIBOR Business Day
prior to the Closing Date, in the case of the first Payment Date) (each, a
"LIBOR Determination Date"). "Telerate Page 3750" means the display designated
as page 3750 on the Telerate Service (or such other page as may replace page
3750 on that service for the purpose of displaying London interbank offered
rates of major banks). If such rate does not appear on such page (or other page
as may replace that page on that service, or if such service is no longer
offered, such other service for displaying LIBOR or comparable rates as may be
reasonably selected by Indenture Trustee), the rate will be the Reference Bank
Rate. The "Reference Bank Rate" will be determined on the basis of the rates at
which deposits in U.S. Dollars are offered by the reference banks (which shall
be three major banks that are engaged in transactions in the London interbank
market, selected by the Manager) as of 11:00 A.M. London time, on the date that
is two LIBOR Business Days prior to the immediately preceding Payment Date to
prime banks in the London interbank market for a period of one month in amounts
approximately equal to the Note Balance then outstanding. The Indenture Trustee
will request the principal London office of each of the reference banks to
provide a quotation of its rate. If at least two such quotations are provided,
the rate will be the arithmetic mean of the quotations. If on such date fewer
than two quotations are provided as requested, the rate will be the arithmetic
mean of the rates quoted by one or more major banks in New York City, selected
 
                                      S-62
<PAGE>   63
 
by the Indenture Trustee as of 11:00 A.M., New York City time, on such date for
loans in U.S. Dollars to leading European banks for a period of one month in
amounts approximately equal to the Note Balance then outstanding. If no such
quotations can be obtained, the rate will be LIBOR for the prior Payment Date.
"LIBOR Business Day" means any day other than (i) a Saturday or a Sunday or (ii)
a day on which banking institutions in the State of New York or in the city of
London, England are required or authorized by law to be closed.
 
SUPPLEMENTAL INTEREST PAYMENTS
 
     The Notes may be entitled to receive Supplemental Interest Payments from
the Note Insurer. "Supplemental Interest Payments" on any Payment Date will
equal the product of (a) the excess, if any, of (x) One-Month LIBOR on the
related LIBOR Determination date over (y) 8.00% and (b) the aggregate Principal
Balances of the Fixed Rate Mortgage Loans and the 5/25 Delayed Adjustment Date
Mortgage Loans in the Mortgage Pool as of the first day of the related Due
Period assuming such Mortgage Loans prepay at a constant prepayment rate of 10%
for the first twenty-fourth months commencing with the Cut-off Date, a constant
prepayment rate of 12.5% for the twenty-fifth up to forty-eighth month, and a
constant prepayment rate of 14% thereafter. Any Supplemental Interest Payments
will be applied to the payment of interest on the Notes to the extent of any
Basis Risk Shortfall on such Payment Date. However if such amount is not
sufficient to cover the Basis Risk Shortfall, a LIBOR Carryover Amount will be
created on such Payment Date. Any amount of Supplemental Interest Payment in
excess of the related Basis Risk Shortfall on such Payment Date will constitute
additional Available Funds to be applied as described at "Payment on the
Notes -- Priority of Payments".
 
THE NOTE PAYMENT ACCOUNT
 
     Pursuant to the Indenture, the Indenture Trustee shall establish and
maintain an account with respect to the Notes (a "Note Payment Account") from
which all payments with respect to the Notes will be made. As described at
"Servicing of the Mortgage Loans -- The Master Servicing Agreement", not later
than the Remittance Date, the Master Servicer will be required pursuant to the
Master Servicing Agreement to wire transfer to the Indenture Trustee for deposit
into the Note Payment Account the sum (without duplication) of all amounts on
deposit in the Collection Account that constitute any portion of Available Funds
for the related Payment Date.
 
     Investment of Note Payment Account. All or a portion of the Note Payment
Account may be invested and reinvested by the Indenture Trustee in one or more
Permitted Investments (as defined in the Indenture) bearing interest or sold at
a discount. The Indenture Trustee or any affiliate thereof may be the obligor on
any investment in the Note Payment Account which otherwise qualifies as a
Permitted Investment. No investment in the Note Payment Account may mature later
than the Business Day preceding the Payment Date.
 
     All income or other gain from investments in the Note Payment Account will
not be available to Noteholders or otherwise subject to any claims or rights of
the Noteholders and will be held in the Note Payment Account for the benefit of
the Indenture Trustee, subject to withdrawal from time to time as permitted by
the Indenture. Any loss resulting from such investments will be for the account
of the Indenture Trustee. The Indenture Trustee will be required to deposit the
amount of any such loss immediately upon the realization of such loss to the
extent such loss will not be offset by other income or gain from investments in
the Note Payment Account and then available for such application.
 
                                      S-63
<PAGE>   64
 
OVERCOLLATERALIZATION
 
     Credit enhancement with respect to the Notes will be provided in part by
overcollateralization resulting from the aggregate Principal Balances of the
Mortgage Loans as of the end of each Due Period exceeding the Note Balance for
the related Payment Date (after taking into account the Monthly Principal and
Excess Cash to be paid on such Payment Date in reduction of the Note Balance).
The Indenture requires that the Overcollateralization Amount (as defined below)
be maintained at the Required Overcollateralization Amount. This maintenance is
intended to be accomplished by the application of monthly Excess Cash to
accelerate the pay-down of the Note Balance until the Overcollateralization
Amount equals the Required Overcollateralization Amount. Such applications of
Excess Cash, because they consist of interest collections on the Mortgage Loans,
but are distributed as principal on the Notes, will increase the
Overcollateralization Amount. Such overcollateralization is intended to result
in amounts received on the Mortgage Loans in excess of the amount necessary to
pay the Monthly Interest Amount and Monthly Principal Amount required to be paid
on the Notes on any Payment Date being applied to reduce the Note Balance to
zero no later than the Stated Maturity of the Notes.
 
     The "Excess Cash" with respect to any Payment Date will be equal to
Available Funds for such Payment Date, reduced by the sum of (i) any amounts
payable to the Note Insurer pursuant to the Insurance Agreement, (ii) the
Monthly Interest Amount for the related Payment Date and (iii) the Monthly
Principal Amount for the related Payment Date.
 
     The "Overcollateralization Amount" with respect to any Payment Date is the
amount, if any, by which (x) the aggregate Principal Balance of the Mortgage
Loans as of the end of the related Due Period exceeds (y) the Note Balance of
the Notes as of such Payment Date after taking into account payments of the
Monthly Principal Amount (disregarding any permitted reduction in Monthly
Principal Amount due to an Overcollateralization Surplus) made on such Payment
Date. The required level of the Overcollateralization Amount with respect to any
Payment Date (the "Required Overcollateralization Amount") will be equal to the
amount specified as such in the Indenture. The Indenture generally provides that
the Required Overcollateralization Amount may, over time, decrease or increase,
subject to certain floors, caps and triggers including triggers that allow the
Required Overcollateralization Amount to decrease or "step down" based on the
performance of the Mortgage Loans with respect to certain delinquency rate tests
specified in the Indenture. In addition, Excess Cash will be applied to the
payment of principal of the Notes during the period that the Mortgage Loans are
unable to meet certain tests specified in the Insurance Agreement based on
delinquency rates. Any increase in the Required Overcollateralization Amount may
result in an accelerated amortization of the Notes until such Required
Overcollateralization Amount is reached. Conversely, any decrease in the
Required Overcollateralization Amount will result in a decelerated amortization
of the Notes until such Required Overcollateralization Amount is reached.
 
     The application of Excess Cash to reduce the Note Balance on any Payment
Date will have the effect of accelerating the amortization of the Notes relative
to the amortization of the Mortgage Loans.
 
     In the event that the Required Overcollateralization Amount is permitted to
decrease or "step down" on any Payment Date in the future, the Indenture will
provide that all or a portion of the Excess Cash that would otherwise be paid to
the Notes on any such Payment Date in reduction of the Note Balance will be
released to the holder(s) of the Investor Certificate.
 
     With respect to any Payment Date, an "Overcollateralization Surplus" means,
the amount, if any, by which (x) the Overcollateralization Amount for such
Payment Date exceeds (y) the then applicable Required Overcollateralization
Amount for such Payment Date. As a technical matter, an Overcollateralization
Surplus may result even prior to the occurrence of any decrease or "step down"
 
                                      S-64
<PAGE>   65
 
in the Required Overcollateralization Amount because the Notes will be entitled
to receive 100% of collected principal on the Mortgage Loans, even though the
Note Balance will, as a result of the accelerated amortization caused by the
application of the Excess Cash, be less than the aggregate Principal Balance of
the Mortgage Loans, in the absence of any Realized Losses (as defined below) on
the Mortgage Loans.
 
     The Indenture will provide that on any Payment Date, all amounts collected
on the Mortgage Loans in respect of principal to be applied on such Payment Date
will be paid to Noteholders in reduction of the Note Balance on such Payment
Date, except as provided above with respect to any Payment Date for which there
exists an Overcollateralization Surplus. If any Mortgage Loan became a
Liquidated Mortgage Loan during such prior Collection Period, the Net
Liquidation Proceeds related thereto and allocated to principal may be less than
the Principal Balance of the related Mortgage Loan; the amount of any such
deficiency is a "Realized Loss." In addition, the Indenture will provide that
the Principal Balance of any Mortgage Loan that becomes a Liquidated Mortgage
Loan shall equal zero. The Indenture will not require that the amount of any
Realized Loss be paid to Noteholders on the Payment Date following the event of
loss. However, the occurrence of a Realized Loss will reduce the
Overcollateralization Amount for the Notes, and will result in more Excess Cash,
if any, being paid on the Notes in reduction of the Note Balance on subsequent
Payment Dates than would be the case in the absence of such Realized Loss.
 
     Overcollateralization and the Insurance Policy.  The Indenture will require
the Indenture Trustee to file a claim for an Insured Payment under the Insurance
Policy not later than 12:00 noon (New York City time) on the third Business Day
prior to any Payment Date as to which the Indenture Trustee has determined that
an Overcollateralization Deficit with respect to the Notes will occur for the
purpose of applying the proceeds of such Insured Payment as a payment of
principal to the Noteholders on such Payment Date. With respect to any Payment
Date, an "Overcollateralization Deficit" will mean the amount, if any, by which
(x) the Note Balance, after taking into account all payments to be made on such
Payment Date in reduction thereof, including any Excess Cash payments, exceeds
(y) the sum of aggregate Principal Balance of the Mortgage Loans as of the end
of the applicable Due Period.
 
REPORTS TO NOTEHOLDERS
 
     Concurrently with each payment to Noteholders, the Indenture Trustee will
mail a statement to each Noteholder, the Note Insurer and the Underwriters in
the form required by the Indenture and setting forth the following information
(to the extent the Master Servicer makes such information (other than the
information described in clause (b) below) available to the Indenture Trustee):

     Collection Period;
 
          (h) the aggregate of the Principal Balances of the Mortgage Loans
     repurchased by the Seller, separately setting forth the aggregate of the
     Principal Balances of Mortgage Loans delinquent for three consecutive

     Indenture;
 
          (i) the Insured Payment, if any, for such Payment Date;

          (k) the Overcollateralization Amount, the then applicable Required
     Overcollateralization Amount, the Overcollateralization Surplus, if any,
     and the Overcollateralization Deficit, if any, with respect to such Payment

          (l) the aggregate outstanding principal balance of the three largest
     outstanding Mortgage Loans;
 
          (m) the Weighted Average Net Loan Rate on the Mortgage Loans as of the
     first day of the month prior to the Payment Date;
 
          (n) the Aggregate Expense Rate with respect to such Payment Date;
 
          (o) the Note Interest Rate for such Payment Date;
 
          (p) the amount of any Supplemental Interest Payments made on such
     Payment Date;
 
          (q) the LIBOR Carryover Amount; and
 
          (r) the unpaid LIBOR Carryover Amount after giving effect to the
     payment of Supplemental Interest Payments, if any.
 
     In the case of information furnished pursuant to clauses (a) and (b) above,
the amounts shall be expressed as a dollar amount per Note with a $1,000
principal denomination.
 
     Within 90 days after the end of each calendar year, the Indenture Trustee
will mail to each person who at any time during such calendar year was a
Noteholder and to the Underwriters, if requested in writing by any such person,
a statement containing the information set forth in clauses (a) and (b) above,
aggregated for such calendar year or, in the case of each person who was a
Noteholder for a portion of such calendar year, setting forth such information
for each month thereof. Such obligation of the Indenture Trustee shall be deemed
to have been satisfied to the extent that substantially comparable information
shall be prepared and furnished by the Indenture Trustee to Noteholders pursuant
to any requirements of the Code as are in force from time to time.
 
     The Indenture Trustee may make available each month, to any interested
party, the monthly statement to Noteholders via the Indenture Trustee's website,
electronic bulletin board and its fax-on-demand service. The Indenture Trustee's
website will be located at www.ctslink.com. The Indenture Trustee's electronic
bulletin board may be accessed by calling (301) 815-6620, and its fax-on-demand
service may be accessed by calling (301) 815-6610.

REDEMPTION OF THE NOTES
 
     The Issuer has the option to redeem the Notes, in whole but not in part, on
any Payment Date after which the then aggregate outstanding Principal Balance of
the Mortgage Loans is less than 20% of their Cut-off Date Principal Balance
(such date, the "Initial Redemption Date"). As discussed at "-- Note Interest
Rate" above, failure of the Issuer to exercise its optional redemption rights at
the Initial Redemption Date will result in the increase in the Formula Rate and
the Cap Rate for such Payment Date and all succeeding Payment Dates.
 
     If the Issuer elects to redeem the Notes it shall, no later than 30 days
prior to the Payment Date selected for redemption, deliver notice of such
election to the Indenture Trustee together with the Redemption Price therefor to
be deposited into the Note Payment Account. The Redemption Price must equal 100%
of the then outstanding Note Balance, plus accrued interest thereon through the
end of the Interest Accrual Period immediately preceding the related Payment
Date; provided, however, that no redemption may take place unless, in connection
with such redemption, (i) any amounts due and owing to the Note Insurer under
the Insurance Agreement are paid in full to the Note Insurer, (ii) any
unreimbursed Master Servicing Fees, Monthly Advances or Servicing Advances,
including Nonrecoverable Advances, are paid in full to the Master Servicer and
(iii) all fees and expenses of the Owner Trustee and the Indenture Trustee have
been paid or reimbursed. There will be no prepayment premium in connection with
such a redemption. Notice of an optional redemption of the Notes must be mailed
by the Indenture Trustee to the Noteholders and the Note Insurer at least ten
days prior to the Payment Date set for such redemption.
 
     The payment on the final Payment Date in connection with the redemption of
the Notes shall be in lieu of the payment otherwise required to be made on such
Payment Date in respect of the Notes.
 
TERMINATION OF THE TRUST
 
     Following the first Payment Date (the "Auction Call Date") on which the
aggregate Principal Balance of the Mortgage Loans is 10% or less of the
aggregate Principal Balance of the Mortgage Loans as of the Cut-off Date, the
Indenture Trustee will be required to solicit competitive bids for the purchase
of the Mortgage Loans for fair market value. In the event that satisfactory bids
are received as described below, the proceeds of such sale shall be used to
redeem the Notes in full and any excess shall be paid to the holder of the
Investor Certificate on the immediately succeeding Payment Date. The Indenture
Trustee will solicit good-faith bids from no fewer than three prospective
purchasers that are considered at the time to be competitive participants in the
residential mortgage loan market, which prospective purchasers may include
AmREIT, the Seller, the Master Servicer or any affiliate thereof. The Indenture
Trustee will consult with the Underwriters and any securities brokerage house
then making a market in the Notes to determine if the fair market value of the
Mortgage Loans has been offered.
 
     If the highest bid received by the Indenture Trustee from a qualified
bidder is not less than the fair market value of the Mortgage Loans and would
equal or exceed the amount set forth in the third succeeding sentence, the
Indenture Trustee must notify the Seller and the Master Servicer of the bid
price. The Seller will have the right of first refusal to purchase the Mortgage
Loans at such bid price (or if the Seller does not exercise such right, the
Master Servicer may exercise such first refusal rights to purchase the Mortgage
Loans at said bid price). If the Seller and the Master Servicer affirmatively
waive their respective first refusal rights, then the Indenture Trustee will
sell and assign such Mortgage Loans without recourse to the highest bidder and
will redeem the Notes. For the Indenture Trustee to consummate the sale, the bid
must be at least equal to an amount, which, when added to Available Funds for
the related Payment Date, would equal the sum, without duplication, of (i) the
accrued interest then due on such Payment Date, (ii) the aggregate Note Balance
as of such Payment Date, (iii) the aggregate of all Insured Payments made by the
Note Insurer to the
 
                                      S-67
<PAGE>   68
 
Noteholders remaining unreimbursed as of such Payment Date and any amounts owing
to the Note Insurer under the Insurance Agreement, plus interest on such amount
calculated at the rate as set forth in the Insurance Agreement, (iv) any accrued
and unpaid Master Servicing Fees and any Servicing Advances and Monthly Advances
(including Nonrecoverable Advances) previously made by the Master Servicer and
remaining unreimbursed as of such Payment Date and (v) any accrued and unpaid
fees and other amounts owing to the Indenture Trustee or the Owner Trustee as of
such Payment Date. If such conditions are not met, the Indenture Trustee will
not consummate such sale. In addition, the Indenture Trustee will decline to
consummate such sale unless it receives an opinion of counsel that such sale
will not give rise to any adverse tax consequences to the Issuer, the Note
Insurer or the Noteholders or adversely affect the opinion that the Notes will
evidence indebtedness of the Issuer under the Code. In the event such sale is
not consummated in accordance with the foregoing, the Indenture Trustee will
continue to solicit bids on a quarterly basis for the purchase of such assets
upon the terms described above.
 
THE INDENTURE TRUSTEE
 
     Norwest Bank Minnesota, National Association, a national banking
association, will be the Indenture Trustee under the Indenture. The Indenture
will provide that the Indenture Trustee is entitled to a fee (the "Indenture
Trustee Fee"), payable monthly on each Payment Date at one-twelfth of 0.005% of
the aggregate Principal Balance of the Mortgage Loans as of the first day of the
related Due Period, and reimbursement of certain expenses. Norwest Bank
Minnesota, National Association, will also perform the functions of calculation
agent and paying agent and will, in addition, provide Noteholders with a monthly
payment report based upon information provided by the Master Servicer and the
necessary information to prepare federal and state tax returns with respect to
the Notes. Upon a termination of the Master Servicer, the Indenture Trustee
shall be obligated to succeed to the obligations of the Master Servicer or to
appoint an eligible successor servicer.
 
     The Indenture also will provide that the Indenture Trustee may resign at
any time, upon notice to the Issuer, the Master Servicer, the Note Insurer and
any Rating Agency, in which event the Note Insurer may (and if the Note Insurer
fails to do so within 60 days, the Issuer will be obligated) to appoint a
successor Indenture Trustee acceptable to the Note Insurer. The Issuer, with the
prior consent of the Note Insurer, may, and if so directed by the Note Insurer,
shall remove the Indenture Trustee if the Indenture Trustee ceases to be
eligible to continue as such under the Indenture or if the Indenture Trustee
becomes insolvent. Any resignation or removal of the Indenture Trustee and
appointment of a successor Indenture Trustee will not become effective until
acceptance of the appointment by the successor Indenture Trustee. The Indenture
will provide that the Indenture Trustee is under no obligation to exercise any
of the rights or powers vested in it by the Indenture at the request or
direction of any of the Noteholders, unless such Noteholders shall have offered
to the Indenture Trustee reasonable security or indemnity against the costs,
expenses and liabilities which might be incurred by it in compliance with such
request or direction. The Indenture Trustee may execute any of the rights or
powers granted by the Indenture or perform any duties thereunder either directly
or by or through its agents or attorneys; provided, however,the Indenture
Trustee shall remain liable for the performance of all of its duties. Pursuant
to the Indenture, the Indenture Trustee is not liable for any action it takes or
omits to take in good faith which it reasonably believes to be authorized by an
authorized officer of any person or within its rights or powers under the
Indenture. The Indenture Trustee and any director, officer, employee or agent of
the Indenture Trustee may rely and will be protected in acting or refraining
from acting in good faith in reliance on any certificate, notice or other
document of any kind prima facie properly executed and submitted by the
authorized officer of any person respecting any matters arising under the
Indenture. The Indenture Trustee will be indemnified by the Trust for certain
losses and other events to the extent described in the Indenture.

VOTING
 
     Unless otherwise specified in the Indenture, with respect to any provisions
of the Indenture providing for the action, consent or approval of the
Noteholders evidencing specified "Voting Interests," each Noteholder will have a
Voting Interest equal to the Percentage Interest represented by such
Noteholder's Note. Unless a Note Insurer Default has occurred and is continuing,
the Voting Interests of the Noteholders will be exercised solely by the Note
Insurer and may be exercised by Noteholders only with the consent of the Note
Insurer.
 
NOTE EVENTS OF DEFAULTS
 
     An "Event of Default" with respect to the Notes shall occur if, on any
Payment Date, after taking into account all payments made in respect of the
Notes on such Payment Date, the Monthly Interest Amount for such Payment Date
remains unpaid or an Overcollateralization Deficit still exists with respect to
the Notes. In addition, a Default under the Insurance Agreement will trigger an
Event of Default under the Indenture. See "The Agreements -- Events of Default;
Rights upon Events of Default" in the Prospectus for a description of the
circumstances under which a default on the Notes, other than a payment default,
may occur. For a description of the rights of Noteholders in connection with any
Event of Default with respect to the Notes, see "The Agreements -- Events of
Default; Rights upon Event of Default" in the Prospectus. In the absence of a
failure by the Note Insurer to pay Insured Payments, no acceleration of the
maturity of the Notes shall be permitted without the consent of the Note
Insurer.
 
AMENDMENT
 
     The Indenture provides that, without the consent of the Holders of any
Notes, but with the consent of the Note Insurer, the Issuer and the Indenture
Trustee, at any time and from time to time, may enter into one or more
supplemental indentures (which will conform to the provisions of the Trust
Indenture Act of 1939, as amended (the "TIA"), as in force at the date of the
execution thereof), in form satisfactory to the Indenture Trustee, for any of
the following purposes: (a) to correct or amplify the description of any
property at any time subject to the lien of the Indenture, or better to assure,
convey and confirm unto the Indenture Trustee any property subject or required
to be subjected to the lien of the Indenture, or to subject to the lien of the
Indenture additional property; (b) to evidence the succession, in compliance
with the applicable provisions of the Indenture, of another entity to the
Issuer, and the assumption by any such successor of the covenants of the Issuer
contained in the Notes or the Indenture; (c) to add to the covenants of the
Issuer for the benefit of the Holders of the Notes, or to surrender any right or
power conferred upon the Issuer in the Indenture; (d) to convey, transfer,
assign, mortgage or pledge any property to or with the Indenture Trustee; (e) to
cure any ambiguity, to correct or supplement any provision in the Indenture or
in any supplemental indenture that may be inconsistent with any other provision
in the Indenture or in any supplemental indenture; (f) to make any other
provisions with respect to matters or questions arising under the Indenture or
in any supplemental indenture; provided, that such action will not materially
and adversely affect the interests of the Noteholders or the Note Insurer; (g)
to evidence and provide for the acceptance of the appointment under the
Indenture by a successor trustee with respect to the Notes and to add to or
change any of the provisions of the Indenture as will be necessary to facilitate
the administration of the trusts thereunder by more than one trustee, pursuant
to the requirements of the Indenture; or (h) to modify, eliminate or add to the
provisions of the Indenture to such extent as will be necessary to effect the
qualification of the Indenture under the
 
                                      S-69
<PAGE>   70
 
TIA or under any similar federal statute enacted after the date of the Indenture
and to add to the Indenture such other provisions as may be expressly required
by the TIA; provided, however, that no such supplemental indentures will be
entered into unless the Indenture Trustee shall have received an Opinion of
Counsel (which shall not be an expense of the Indenture Trustee) to the effect
that entering into such supplemental indenture will not have any material
adverse tax consequences to the Noteholders. Any such amendment or supplement to
the Indenture shall be deemed not to adversely affect in any material respects
the interests of the Noteholders if the Indenture Trustee receives written
confirmation from each Rating Agency that such amendment will not cause such
Rating Agency to reduce the then current rating of the Notes.
 
     The Indenture also provides that the Issuer and the Indenture Trustee, when
authorized by a written request of the Issuer, also may, with prior notice to
the Note Insurer and each Rating Agency and with the consent of the Note Insurer
and the Holders of Notes affected thereby representing not less than 66 2/3% of
the aggregate Voting Interest thereof, enter into a supplemental indenture for
the purpose of adding any provisions to, or changing in any manner or
eliminating any of the provisions of, the Indenture or of modifying in any
manner the rights of the Noteholders thereunder; provided, that no such
supplemental indenture may, without the consent of the Holder of each Note
affected thereby: (a) change the date of payment of any installment of principal
of or interest on any Note, or reduce the principal amount thereof or the
interest rate thereon, change the provisions of the Indenture relating to the
application of collections on, or the proceeds of the sale of, the corpus of the
Trust to payment of principal of or interest on the Notes, or change any place
of payment where, or the coin or currency in which, any Note or the interest
thereon is payable, or impair the right to institute suit for the enforcement of
the provisions of the Indenture requiring the application of funds available
therefor to the payment of any such amount due on the Notes on or after the
respective dates such amounts become due; (b) reduce the percentage of the Note
Balances of the Notes, the consent of the Holders of which is required for any
such supplemental indenture, or the consent of the Holders of which is required
for any waiver of compliance with certain provisions of the Indenture or certain
defaults thereunder and their consequences provided for in the Indenture; (c)
modify or alter the provisions of the proviso to the definition of the term
"Outstanding" in the Indenture or modify or alter the exception in the
definition of the term "Holder" therein; (d) reduce the percentage of the Note
Balance of the Notes required to direct the Indenture Trustee to direct the
Issuer to sell or liquidate the corpus of the Trust pursuant to the Indenture;
(e) modify any provision of the amendment provisions of the Indenture except to
increase any percentage specified in the Indenture or to provide that certain
additional provisions of the Indenture or the other Agreements cannot be
modified or waived without the consent of the Holder of each Note affected
thereby; (f) modify any of the provisions of the Indenture in such manner as to
affect the calculation of the amount of any payment of interest or principal due
on any Note on any Payment Date (including the calculation of any of the
individual components of such calculation); or (g) permit the creation of any
lien ranking prior to or on a parity with the lien of the Indenture with respect
to any part of the Trust Estate or, except as otherwise permitted or
contemplated in the Indenture, terminate the lien of the Indenture on any
property at any time subject thereto or deprive the Holder of any Note of the
security provided by the lien of the Indenture; and provided, further, that such
action will not, as evidenced by an Opinion of Counsel (which shall not be an
expense of the Indenture Trustee), cause the Trust to be subject to an entity
level tax.
 
                              THE INSURANCE POLICY
 
     The following summary of the terms of the Insurance Policy does not purport
to be complete and is qualified in its entirety by reference to the Insurance
Policy. A form of the Insurance Policy (without exhibits) may be obtained, upon
written request, without charge, from the Seller at

American Residential Eagle, Inc., 445 Marine View Avenue, Suite 100, Del Mar,
California 92614, Attention: Portfolio Manager.
 
     Simultaneously with the issuance of the Notes, the Note Insurer will
deliver the Insurance Policy to the Indenture Trustee for the benefit of the
Noteholders. Under the Insurance Policy, the Note Insurer will irrevocably and
unconditionally guarantee payment on each Payment Date to the Indenture Trustee
for the benefit of the holders of the Notes the full and complete payment of
Insured Payments with respect to the Notes, calculated in accordance with the
original terms of the Notes when issued and without regard to any amendment or
modification of the Notes or the Agreement except amendments or modifications to
which the Note Insurer has given its prior written consent. "Insured Payments"
shall mean with respect to the Notes as of any Payment Date (i) the Monthly
Interest Amount for the related Interest Accrual Period net of Relief Act
Shortfalls and Prepayment Interest Shortfalls, (ii) the Supplemental Interest
Payment for such Payment Date, (iii) the Overcollateralization Deficit on such
Payment Date, and (iv) the Note Balance of the Notes to the extent unpaid on the
final Payment Date or earlier termination of the Trust pursuant to the terms of
the Indenture.
 
     Payment of claims under the Insurance Policy in respect of Insured Payments
will be made by the Note Insurer following Receipt by the Note Insurer of the
appropriate notice for payment on the later to occur of (a) 12:00 noon, New York
City time, on the second Business Day following Receipt of such notice for
payment, and (b) 12:00 noon, New York City time, on the relevant Payment Date.
 
     The Note Insurer shall be entitled to pay any amount under the Insurance
Policy in respect of Insured Payments, including any acceleration payment,
whether or not any notice and certificate shall have been received by the Note
Insurer as provided above, provided, however, that by acceptance of the
Insurance Policy the Indenture Trustee agrees to provide upon request to the
Note Insurer a notice and certificate in respect of any such payments made by
the Note Insurer. The Note Insurer shall be entitled to pay principal under the
Insurance Policy on an accelerated basis if the Note Insurer shall so select in
its sole discretion, at any time or from time to time, in whole or in part, at
an earlier Payment Date than provided in the definition of "Insured Payments,"
if such principal would have been payable under the Agreement were funds
sufficient to make such payment available to the Indenture Trustee for such
purpose. Insured Payments insured by the Insurance Policy shall not include
interest, in respect of principal paid under the Insurance Policy on an
accelerated basis, accruing from after the date of such payment of principal.
 
     If any Insured Payment is avoided as a preference payment under applicable
bankruptcy, insolvency, receivership or similar law, the Note Insurer will pay
such amount out of funds of the Note Insurer on the later of (a) the date when
due to be paid pursuant to the Order referred to below or (b) the first to occur
of (i) the fourth Business Day following Receipt by the Note Insurer from the
Indenture Trustee of (A) a certified copy of the order of the court or other
governmental body which exercised jurisdiction to the effect that a holder of
Notes is required to return principal or interest distributed with respect to a
Note during the Term of the Insurance Policy because such distributions were
avoidable preferences under applicable bankruptcy law (the "Order"), (B) a
certificate of such holder of Notes that the Order has been entered and is not
subject to any stay, and (C) an assignment duly executed and delivered by such
holder of Notes, in such form as is reasonably required by the Note Insurer and
provided to such holder of Notes by the Note Insurer, irrevocably assigning to
the Note Insurer all rights and claims of such holder of Notes against the
debtor which made such preference payment or otherwise with respect to such
preference payment, or (ii) the date of Receipt by the Note Insurer from the
Indenture Trustee of the items referred to in clauses (A), (B) and (C) above if,
at least four Business Days prior to such date of Receipt, the Note Insurer
shall have Received written notice from the Indenture Trustee that such items
were to be delivered on such date and such date was specified in such notice.
Such payment shall be
 
                                      S-71
<PAGE>   72
 
disbursed to the receiver, conservator, debtor-in-possession or trustee in
bankruptcy named in the Order and not to the Indenture Trustee or holder of
Notes directly (unless a holder of Notes has previously paid such amount to the
receiver, conservator, debtor-in-possession or trustee in bankruptcy named in
the Order, in which case such payment shall be disbursed to the Indenture
Trustee for distribution to such Noteholder upon proof of such payment
reasonably satisfactory to the Note Insurer). In connection with the foregoing,
the Note Insurer shall have the rights provided pursuant to the Agreement.
 
     The terms "Receipt" and "Received," with respect to the Insurance Policy,
mean actual delivery to the Note Insurer and to its fiscal agent appointed by
the Note Insurer at its option, if any, prior to 12:00 P.M., New York City time,
on a Business Day; delivery either on a day that is not a Business Day or after
12:00 P.M., New York City time, shall be deemed to be Receipt on the next
succeeding Business Day. If any notice or certificate given under the Insurance
Policy by the Indenture Trustee is not in proper form or is not properly
completed, executed or delivered, it shall be deemed not to have been Received,
and the Note Insurer or the fiscal agent shall promptly so advise the Indenture
Trustee and the Indenture Trustee may submit an amended notice.
 
     Under the Insurance Policy, "Business Day" means any day other than (i) a
Saturday or Sunday or (ii) a day on which banking institutions in the City of
New York, New York, the State of New York or in the city in which the corporate
trust office of the Indenture Trustee is located, are authorized or obligated by
law or executive order to be closed. The Note Insurer's obligations under the
Insurance Policy to make Insured Payments shall be discharged to the extent
funds are transferred to the Indenture Trustee as provided in the Insurance
Policy, whether or not such funds are properly applied by the Indenture Trustee.
 
     "Term of the Insurance Policy" means the period from and including the date
of issuance of the Insurance Policy to and including the date on which the Note
Balance of the Notes is zero, plus such additional period, to the extent
specified in the Insurance Policy, during which any payment on the Notes could
be avoided in whole or in part as a preference payment.
 
     The Note Insurer shall be subrogated to the rights of the holders of the
Notes to receive payments of principal and interest, as applicable, with respect
to distributions on the Notes to the extent of any payment by the Note Insurer
under the Insurance Policy. To the extent the Note Insurer makes Insured
Payments, either directly or indirectly (as by paying through the Indenture
Trustee), to the holders of the Notes, the Note Insurer will be subrogated to
the rights of the holders of the Notes, as applicable, with respect to such
Insured Payment and shall be deemed to the extent of the payments so made to be
a registered holder of Notes for purposes of payment.
 
     The Insurance Policy is governed by the laws of the State of New York. The
Insurance Policy is not covered by the Property/Casualty Insurance Security Fund
specified in Article 76 of the New York Insurance Law.
 
     To the fullest extent permitted by applicable law, the Note Insurer agrees
under the Insurance Policy not to assert, and waives, for the benefit of each
holder of Notes, all its rights (whether by counterclaim, setoff or otherwise)
and defenses (including, without limitation, the defense of fraud), whether
acquired by subrogation, assignment or otherwise, to the extent that such rights
and defenses may be available to the Note Insurer to avoid payment of its
obligations under the Insurance Policy in accordance with the express provisions
of the Insurance Policy.
 
     Claims under the Insurance Policy constitute direct, unsecured and
unsubordinated obligations of the Note Insurer ranking not less than pari passu
with other unsecured and unsubordinated indebtedness of the Note Insurer for
borrowed money. Claims against the Note Insurer under the Insurance Policy and
claims against the Note Insurer under each other financial guaranty insurance
policy issued thereby constitute pari passu claims against the general assets of
the Note Insurer. The
 
                                      S-72
<PAGE>   73
 
terms of the Insurance Policy cannot be modified or altered by any other
agreement or instrument, or by the merger, consolidation or dissolution of the
Depositor. The Insurance Policy may not be cancelled or revoked prior to payment
in full of the Notes.
 
     Pursuant to the terms of the Master Servicing Agreement and the Indenture,
unless a Note Insurer Default exists, the Note Insurer will be entitled to
exercise certain rights of the holders of the Notes, without the consent of such
Noteholders, and the holders of the Notes may exercise such rights only with the
prior written consent of the Note Insurer.
 
     The Issuer, the Depositor, AmREIT, the Seller and the Note Insurer will
enter into an Insurance and Indemnity Agreement (the "Insurance Agreement")
pursuant to which the Depositor, AmREIT and the Seller will agree to reimburse,
with interest, the Note Insurer for amounts paid pursuant to claims under the
Insurance Policy. AmREIT, the Depositor, and the Seller will further agree to
pay the Note Insurer all reasonable charges and expenses which the Note Insurer
may pay or incur relative to any amounts paid under the Insurance Policy or
otherwise in connection with the transaction and to indemnify the Note Insurer
against certain liabilities. Except to the extent provided therein, amounts
owing under the Insurance Agreement will be payable solely from the Trust. An
"event of default" by AmREIT or the Seller under the Insurance Agreement
includes (i) a failure by AmREIT, the Seller or the Depositor to pay when due
any amount owed under the Insurance Agreement or certain other Basic Documents,
(ii) the untruth or incorrectness in any material respect of any representation
or warranty of AmREIT, the Seller or the Depositor in the Insurance Agreement or
certain other Basic Documents, (iii) a failure by AmREIT, or the Seller or the
Depositor to perform or to observe any covenant or agreement in the Insurance
Agreement, the Master Servicing Agreement or certain other Basic Documents, (iv)
a failure by either AmREIT, the Seller or the Depositor to pay its debts in
general or the occurrence of certain events of insolvency or bankruptcy with
respect to AmREIT or the Seller, (v) the occurrence of Master Servicer Event of
Default under the Master Servicing Agreement, (vi) the failure of the Mortgage
Loans to meet certain loss and delinquency tests set forth in the Insurance
Agreement and (vii) a claim is made under the Insurance Policy (excluding any
Supplemental Interest Payment which is reimbursed on the related Payment Date
under the swap arrangement) which is not timely reimbursed by the Trust under
the terms of the Insurance Policy.
 
                                THE NOTE INSURER
 
     The following information has been provided by Financial Security Assurance
Inc. (the "Note Insurer") for inclusion in this Prospectus Supplement. No
representation is made by the Depositor or the Underwriter as to the accuracy
and completeness of such information.
 
GENERAL
 
     The Note Insurer is a monoline insurance company incorporated in 1984 under
the laws of the State of New York. The Note Insurer is licensed to engage in the
financial guaranty insurance business in all 50 states, the District of Columbia
and Puerto Rico.
 
     The Note Insurer and its subsidiaries are engaged in the business of
writing financial guaranty insurance, principally in respect of securities
offered in domestic and foreign markets. In general, financial guaranty
insurance consists of the issuance of a guaranty of scheduled payments of an
issuer's securities -- thereby enhancing the credit rating of those
securities -- in consideration for the payment of a premium to the insurer. The
Note Insurer and its subsidiaries principally insure asset-backed,
collateralized and municipal securities. Asset-backed securities are generally
supported by residential mortgage loans, consumer or trade receivables,
securities or other assets having an ascertainable cash flow or market value.
Collateralized securities include public utility first mortgage
 
                                      S-73
<PAGE>   74
 
bonds and sale/leaseback obligation bonds. Municipal securities consist largely

                  CERTAIN PREPAYMENT AND YIELD CONSIDERATIONS
 
GENERAL
 
     The rate of principal payments on the Notes, the aggregate amount of
payment on the Notes and the yield to maturity of the Notes will be related to
the rate and timing of payments of principal on the Mortgage Loans, the amount
and timing of mortgagor delinquencies and defaults resulting in realized losses,
and the application of Excess Cash on the Notes. Such yield may be adversely
affected by a higher or lower anticipated rate of principal payments (including
principal prepayments) on the Mortgage Loans. The rate of principal payments on
the Mortgage Loans will in turn be affected by the amortization schedules of the
Mortgage Loans and by the rate of principal prepayments (including for this
purpose prepayments resulting from refinancing, liquidations of the Mortgage
Loans due to defaults, casualties, condemnations and repurchases by the Seller).
 
THE EFFECT OF THE NOTE INTEREST RATE ON YIELD
 
     The Note Interest Rate is subject to the applicable Net Funds Cap. See
"Description of the Notes -- Note Interest Rate." The Net Funds Cap on any
Payment Date is determined, in part, by reference to the weighted average Loan
Rate of the Mortgage Loans minus the Aggregate Expense Rate (the "Weighted
Average Net Loan Rate"). All of the Loan Rates on the Fixed Rate Mortgage Loans
(approximately 28% of the Mortgage Loans by Principal Balance as of the
Statistical Cut-off Date) are fixed for the lives of such Mortgage Loans. If
Mortgage Loans bearing higher Loan Rates were to prepay at faster rates than
Mortgage Loans with lower Loan Rates, the Net Funds Cap would be lower than
otherwise would be the case, thus have an adverse effect on yield.
 
     The yield to investors in the Notes also will be sensitive to, among other
things, the level of One-Month LIBOR (as defined herein) and the levels of the
Index. Substantially all of the Adjustable Rate Mortgage Loans are Delayed
Adjustment Mortgage Loans which will bear interest at fixed Loan Rates for 24,
36 or 60 months, after origination of such Mortgage Loans. Although each
 
                                      S-76
<PAGE>   77
 
of the Adjustable Rate Mortgage Loans bears interest at an adjustable rate, such
rate is subject to a Periodic Rate Cap, a Minimum Loan Rate and a Maximum Loan
Rate. If the Index increases substantially between Adjustment Dates, the
adjusted Loan Rate on the related Mortgage Loan may not equal the Index plus the
related Gross Margin due to the constraint of such caps and floors. In such
event, the related Loan Rate will be less than would have been the case in the
absence of such caps. In addition, the Loan Rate applicable to any Adjustment
Date will be based on the Index related to the Adjustment Date. Thus, if the
value of the Index with respect to a Mortgage Loan rises, the lag in time before
the corresponding Loan Rate increases will, all other things being equal, slow
the upward adjustment of the Net Funds Cap. Furthermore, Mortgage Loans that
have not reached their first Adjustment Date are more likely to be subject to
the applicable Periodic Rate Cap on their first Adjustment Date. See "The
Mortgage Pool" herein. Although the Holders of the Notes will be entitled to
receive the related LIBOR Carryover Amount (as defined herein) to the extent
funds are available as described herein, and in the priority set forth herein,
there is no assurance that sufficient funds will be available therefor.
 
     Although the Loan Rates on the Adjustable Rate Mortgage Loans are subject
to adjustment, the Loan Rates adjust less frequently than the Note Interest
Rates and adjust by reference to the Index. In addition a Delayed Adjustment
Mortgage Loan may not have a first adjustment date for a period of up to five
years following origination. Changes in One-Month LIBOR may not correlate with
changes in the Index and may not correlate with prevailing interest rates. It is
possible that an increased level of One-Month LIBOR could occur simultaneously,
thereby reducing the weighted average lives of the Notes.
 
PREPAYMENTS
 
     Prepayments, liquidations and purchases of the Mortgage Loans (including
any optional purchase by the Seller of a delinquent Mortgage Loan and any
optional purchase of the remaining Mortgage Loans in connection with the
termination of the Trust) will result in distributions on the Notes of principal
amounts which would otherwise be distributed over the remaining terms of such
Mortgage Loans. Since the rate of payment of principal of the Mortgage Loans
will depend on future events and a variety of factors, no assurance can be given
as to such rate or the rate of principal prepayments. The extent to which the
yield to maturity of a Note may vary from the anticipated yield will depend upon
the degree to which a Note is purchased at a discount or premium, and the degree
to which the timing of payments thereon is sensitive to prepayments,
liquidations and purchases of such Mortgage Loans.
 
     The rate of prepayment on the Mortgage Loans cannot be predicted. All of
the Mortgage Loans may be prepaid in whole or in part at any time. A majority of
the Mortgage Loans are subject to prepayment charges under certain circumstances
if prepaid in full or in part during a period ranging from one to five years
after origination. The Mortgage Pools' prepayment experience may be affected by
a wide variety of factors, including general economic conditions, interest
rates, the availability of alternative financing and homeowner mobility. In
addition, all of the Mortgage Loans contain due-on-sale provisions and the
Master Servicer will be required by the Agreement to enforce such provisions
unless (i) such enforcement is not permitted by applicable law or (ii) the
Master Servicer, in a manner consistent with accepted servicing practices,
permits the purchaser of the related Mortgaged Property to assume the Mortgage
Loan. The enforcement of a "due-on-sale" provision will have the same effect as
a prepayment of the related Mortgage Loan. To the extent permitted by applicable
law, such assumption will not release the original borrower from its obligation
under any such Mortgage Loan. See "Certain Legal Aspects of Loans -- Due-on-Sale
Clauses in Mortgage Loans" in the Prospectus.
 
                                      S-77
<PAGE>   78
 
     As with fixed rate obligations generally, the rate of prepayment on a pool
of mortgage loans with fixed rates such as the Fixed Rate Mortgage Loans is
affected by prevailing market rates for mortgage loans of a comparable term and
risk level. When the market interest rate is below the interest rate on a
mortgage loan, mortgagors may have an increased incentive to refinance their
mortgage loans. Depending on prevailing market rates, the future outlook for
market rates and economic conditions generally, some mortgagors may sell or
refinance mortgaged properties in order to realize their equity in the mortgaged
properties, to meet cash flow needs or to make other investments.
 
     As is the case with conventional fixed rate mortgage loans, adjustable rate
mortgage loans may be subject to a greater rate of principal prepayments in a
declining interest rate environment. For example, if prevailing interest rates
fall significantly, adjustable rate mortgage loans could be subject to higher
prepayment rates than if prevailing interest rates remain constant because the
availability of fixed rate mortgage loans at competitive interest rates may
encourage mortgagors to refinance their adjustable rate mortgage loans to "lock
in" a lower fixed interest rate. The existence of the applicable Periodic Rate
Cap, Maximum Loan Rate and Minimum Loan Rate also may affect the likelihood of
prepayments. In addition, the delinquency and loss experience of adjustable rate
mortgage loans may differ from that of fixed rate mortgage loans because the
amount of the monthly payments on the adjustable rate mortgage loans are subject
to adjustment on each Adjustment Date. However, no assurance can be given as to
the level of prepayments that the Mortgage Loans will experience.
 
     The rate of prepayments on the Mortgage Loans is sensitive to the credit
standing of the borrower, which may improve and thereby allow the borrower to
refinance on more favorable terms, or may decline and thereby limit the
borrower's ability to refinance. The rate of prepayments on the Delayed
Adjustment Mortgage Loans which are in the initial fixed rate period, are
sensitive to prevailing interest rates. The prepayment behavior of such Mortgage
Loans may differ from that of the other Mortgage Loans. As a Delayed Adjustment
Mortgage Loan approaches its initial Adjustment Date, the borrower may become
more likely to refinance such loan to avoid an increase in the Loan Rate, even
if Fixed Rate Mortgage Loans are only available at rates that are slightly lower
or higher than the Loan Rate before adjustment.
 
     The rate of defaults on the Mortgage Loans will also affect the rate and
timing of principal payments on the Mortgage Loans. As a result of the
underwriting guidelines applicable to the Mortgage Loans, the Mortgage Loans are
likely to experience rates of delinquency, foreclosure, bankruptcy and loss that
are higher, and that may be substantially higher, than those experienced by
mortgage loans underwritten in accordance with the standards applied by FNMA and
FHLMC mortgage loan purchase programs. See "The Mortgage Pool -- Underwriting
Guidelines." In addition, because of such underwriting criteria and their likely
effect on the delinquency, foreclosure, bankruptcy and loss experience of the
Mortgage Loans, the Mortgage Loans will generally be serviced in a manner
intended to result in a faster exercise of remedies, which may include
foreclosure, in the event Mortgage Loan delinquencies and defaults occur, than
would be the case of the Mortgage Loans were serviced in accordance with such
other programs. Furthermore, the rate and timing of prepayments, defaults and
liquidations on the Mortgage Loans will be affected by the general economic
condition of the region of the country in which the related Mortgaged Properties
are located. The risk of delinquencies and loss is greater and prepayments are
less likely in regions where a weak or deteriorating economy exists, as may be
evidenced by, among other factors, increasing unemployment or falling property
values. To the extent that the locations of the Mortgaged Properties are
concentrated in a given region, the risk of delinquencies, loss and involuntary
prepayments resulting from adverse economic conditions in such region or from
other factors, such as fires, storms, landslides and mudflows and earthquakes,
is increased. Certain information regarding the geographic concentration of the
Mortgaged Properties is set forth under "The Mortgaged Pool -- Characteristics
of Adjustable Rate Mortgage Loans" and "-- Characteristics of Fixed Rate
Mortgage Loans."
 
                                      S-78
<PAGE>   79
 
     Certain of the Fixed Rate Mortgage Loans are Balloon Loans. Balloon Loans
involve a greater degree of risk than fully amortizing loans because the ability
of the borrower to make a Balloon Payment typically will depend upon its ability
either to refinance the loan or to sell the related Mortgaged Property. The
ability of a borrower to accomplish either of these goals will be affected by a
number of factors, including the level of available mortgage rates at the time
of the attempted sale or refinancing, the borrower's equity in the related
Mortgaged Property, the financial condition of the borrower and operating
history of the related Mortgaged Property, tax laws, prevailing economic
conditions and the availability of credit for home equity borrowers in general.
 
     To the extent that principal prepayments with respect to the Mortgage Loans
result in prepayments on the Notes during periods of generally lower interest
rates, Noteholders may be unable to reinvest such principal prepayments in
securities having a yield and rating comparable to the Notes.
 
     The average life of the Notes and, if purchased at other than par, the
yield realized by holders of the Notes will be sensitive to levels of payment
(including prepayments) on the Mortgage Loans. In general, the yield on a Note
that is purchased at a premium from the outstanding principal amount thereof,
may be adversely affected by a higher than anticipated level of prepayments of
the Mortgage Loans. Conversely, the yield on a Note that is purchased at a
discount from the outstanding principal amount thereof may be adversely affected
by a lower than anticipated level of prepayments.
 
     Because all amounts available for payment on the Notes after payments in
respect of interest on the Notes (except as set forth herein), including all or
a portion of the Excess Cash, are applied as reductions of the Note Balance, the
weighted average life of the Notes will also be influenced by the amount of
Excess Cash so applied. Because Excess Cash attributable to the
overcollateralization feature is derived from interest collections on the
Mortgage Loans and will be applied to reduce the Note Balance, the aggregate
payments in reduction of the Note Balance on a Payment Date will usually be
greater than the aggregate amount of principal payments (including Principal
Prepayments) on the Mortgage Loans payable on such Payment Date in order to
maintain Required Overcollateralization Amount. As a consequence, Excess Cash
available for payment in reduction of the Note Balance for the Notes will
increase in proportion to the outstanding Note Balance over time in the absence
of offsetting Realized Losses for the Mortgage Loans.
 
     Excess Cash will be paid on the Notes in reduction of the Note Balance on
each Payment Date to the extent the then applicable Required
Overcollateralization Amount exceeds the related Overcollateralization Amount on
such Payment Date. Any remaining Excess Cash will be released to the holder of
the Investor Certificate. If a Note is purchased at other than par, its yield to
maturity will be affected by the rate at which the Excess Cash is paid to the
Noteholders. If the actual rate of Excess Cash payments on the Notes applied in
reduction of the Note Balance is slower than the rate anticipated by an investor
who purchases a Note at a discount, the actual yield to such investor will be
lower than such investor's anticipated yield. If the actual rate of Excess Cash
payments applied in reduction of the Note Balance is faster than the rate
anticipated by an investor who purchases a Note at a premium, the actual yield
to such investor will be lower than such investor's anticipated yield. The
amount of Excess Cash on any Payment Date will be affected by, among other
things, the actual amount of interest received, collected or recovered in
respect of the Mortgage Loans during the related Collection Period and such
amount will be influenced by changes in Six-Month LIBOR, the weighted average of
the Loan Rates resulting from prepayment and liquidations of the Mortgage Loans.
The amount of Excess Cash paid to the Noteholders applied to the Note Balance on
each Payment Date will be based on the Required Overcollateralization Amount.
The Indenture generally provides that the Required Overcollateralization Amount
may, over time, decrease, or increase, subject to certain floors, caps and
triggers, including triggers that allow the Required Overcollateralization
Amount to decrease or "step down" based on the performance on the Mortgage Loans
with
 
                                      S-79
<PAGE>   80
 
respect to certain tests specified in the Indenture based on delinquency rates.
Any increase in the Required Overcollateralization Amount may result in an
accelerated amortization until such Required Overcollateralization Amount is
reached. Conversely, any decrease in the Required Overcollateralization Amount
will result in a decelerated amortization of the Notes until such Required
Overcollateralization Amount is reached.
 
STATED MATURITY DATE
 
     The "Stated Maturity Date" for the Notes is the Payment Date in April 2029
which is the Payment Date in the third month immediately following the last
scheduled due date for the Mortgage Loan having the latest stated maturity date.
For the reasons discussed above at "-- Prepayments" it is expected that the
actual last Payment Date for the Notes will occur significantly earlier than the
Stated Maturity Date for the Notes specified above.
 
WEIGHTED AVERAGE LIVES
 
     Generally, greater than anticipated prepayments of principal will increase
the yield on the Notes purchased at a price less than par and will decrease the
yield on the Notes purchased at a price greater than par. The effect on an
investor's yield due to principal prepayments on the Mortgage Loans occurring at
a rate that is faster (or slower) than the rate anticipated by the investor in
the period immediately following the issuance of the Notes will not be entirely
offset by a subsequent like reduction (or increase) in the rate of principal
payments. The weighted average life of the Notes will also be affected by the
amount and timing of delinquencies and defaults on the Mortgage Loans and the
recoveries, if any, on defaulted Mortgage Loans and foreclosed properties.
 
     The "weighted average life" of a Note refers to the average amount of time
that will elapse from the date of issuance to the date each dollar in respect of
principal of such Note is repaid. The weighted average life of the Notes will be
influenced by, among other factors, the rate at which principal payments are
made on the Mortgage Loans, including final payments made upon the maturity of
Balloon Loans.
 
     Prepayments on Mortgage Loans are commonly measured relative to a
prepayment model or standard. The models used in this Prospectus Supplement
("Prepayment Models") are based on an assumed rate of prepayment each month of
the then unpaid principal balance of a pool of mortgage loans similar to the
Mortgage Loans. The Prepayment Model used in this Prospectus Supplement
("Constant Prepayment Rate" or "CPR") is a prepayment assumption which
represents a constant assumed rate or prepayment each month relative to the then
outstanding principal balance of a pool of mortgage loans for the life of such
mortgage loans. 27% CPR assumes a constant prepayment rate of 27%.
 
     There is no assurance, however, that prepayments on the Mortgage Loans will
conform to any level of the Prepayment Model, and no representation is made that
the Mortgage Loans will prepay at the prepayment rates shown or any other
prepayment rate. The rate of principal payments on pools of mortgage loans is
influenced by a variety of economic, geographic, social and other factors,
including the level of interest rates. Other factors affecting prepayment of
mortgage loans include changes in obligors' housing needs, job transfers and
unemployment. In the case of mortgage loans 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 remain at or above the rates borne by such mortgage
loans. Conversely, if prevailing interest rates rise above the interest on such
mortgage loans, the rate of prepayment would be expected to decrease.

DECREMENT TABLES
 
     Subject to the foregoing discussion and assumptions, the following tables
set forth the percentages of the Note Balance that would be outstanding after
each of the dates shown at various percentages of the Prepayment Assumption and
the weighted average life.
 
     Since the tables were prepared on the basis of the Structuring Assumptions,
there are discrepancies between characteristics of the actual Mortgage Loans and
the characteristics of the Mortgaged Loans assumed in preparing the tables. Any
such discrepancy may have an effect upon the percentages of the Note Balance
outstanding and weighted average life of the Notes set forth in the table. In
addition, since the actual Mortgage Loans in the Mortgage Pool have
characteristics which differ from those assumed in preparing the tables set
forth below, the payments of principal on the Notes may be made earlier or later
than as indicated in the table.
 
                      PERCENT OF NOTE BALANCE OUTSTANDING
           AT THE FOLLOWING PERCENTAGES OF THE PREPAYMENT ASSUMPTION

                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
GENERAL
 
     The following discussion, which summarizes certain material U.S. federal
income tax aspects of the purchase, ownership and disposition of the Notes, is
based on the provisions of the Internal Revenue Code of 1986, as amended (the
"Code"), the Treasury Regulations thereunder, and published rulings and court
decisions in effect as of the date hereof, all of which are subject to change,
possibly retroactively. This discussion does not address every aspect of the
U.S. federal income tax laws which may be relevant to beneficial owners of the
Notes ("Noteowners") in light of their personal investment circumstances or to
certain types of Noteowners subject to special treatment under the U.S. federal
income tax laws (for example, banks and life insurance companies). Accordingly,
investors should consult their tax advisors regarding U.S. federal, state,
local, foreign and any other tax consequences to them of investing in the Notes.
 
CHARACTERIZATION OF THE NOTES AS INDEBTEDNESS
 
     Based on the application of existing law to the facts as set forth in the
Basic Documents and other relevant documents and assuming compliance with the
terms of the Basic Documents as in effect on the date of issuance of the Notes,
Jeffers, Wilson, Shaff & Falk, LLP special tax counsel to the Depositor and the
Seller ("Tax Counsel"), is of the opinion that (i) the Notes will be treated as
debt instruments for federal income tax purposes as of such date and (ii) the
Trust will not be characterized as an association (or publicly traded
partnership) taxable as a corporation or as a taxable mortgage pool within the
meaning of Section 7701(i) of the Code. Accordingly, upon issuance, the Notes
will be treated as "Debt Securities" as described in the Prospectus. See
"Certain Federal Income Tax Considerations -- Taxation of Debt Securities and
"-- Tax Consequences to Holders of the Notes" in the Prospectus.
 
     The Depositor and the Noteowners express in the Mortgage Loan Purchase
Agreement their intent that, for applicable tax purposes, the Notes will be
indebtedness secured by the Mortgage Loans. The Depositor and the Noteowners, by
accepting the Notes, and each Noteowner by its acquisition of a beneficial
interest in a Note, have agreed to treat the Notes as indebtedness for U.S.
federal income tax purposes.
 
TAXATION OF INTEREST INCOME OF NOTEOWNERS
 
     Assuming that the Noteowners are holders of debt obligations for U.S.
federal income tax purposes, the Notes generally will be taxable as Debt
Securities. See "Certain Federal Income Tax Considerations -- Taxation of Debt
Securities" and "-- Tax Consequences to the Holders of the Notes" in the
Prospectus.
 
     While it is not anticipated that the Notes will be issued at a greater than
de minimis discount, under Treasury regulations (the "OID Regulations") it is
possible that the Notes could nevertheless be deemed to have been issued with
original issue discount ("OID") if the interest were not treated as
unconditionally payable under the OID Regulations. If such regulations were to
apply, all of the taxable income to be recognized with respect to the Notes
would be includible in income of Noteowners as OID, but would not be includible
again when the interest is actually received. See "Certain Federal Income Tax
Considerations -- Taxation of Debt Securities" and "-- Tax Consequences to
Holders of the Notes" in the Prospectus for a discussion of the application of
the OID rules if the Notes are in fact issued at a greater than de minimis
discount or are treated as having been issued with OID under the OID
Regulations. For purposes of calculating OID, it is likely that scheduled
interest payments due on the Notes will be treated as "Qualified Stated
Interest" as defined in Section 1.1273-1(c) of the OID Regulations.
 
                                      S-84
<PAGE>   85
 
FOREIGN INVESTORS
 
     In general, subject to certain exceptions, interest (including OID) paid on
a Note to a nonresident alien individual, foreign corporation or other
non-United States person is not subject to U.S. federal income tax, provided
that such interest is not effectively connected with a trade or business of the
recipient in the United States and the Noteowner provides the required foreign
person information certification. See "Certain Federal Income Tax
Considerations -- Tax Treatment of Foreign Investors" in the Prospectus.
 
BACKUP WITHHOLDING
 
     Certain Noteowners may be subject to backup withholding at the rate of 31%
with respect to interest paid on the Notes if the Noteowners, upon issuance,
fail to supply the Indenture Trustee or his broker with his taxpayer
identification number, furnish an incorrect taxpayer identification number, fail
to report interest, dividends, or other "reportable payments" (as defined in the
Code) property, or, under certain circumstances, fail to provide the Indenture
Trustee or his broker with a certified statement, under penalty of perjury, that
he is not subject to backup withholding.
 
     The Indenture Trustee will be required to report annually to the IRS, and
to each Noteowner of record, the amount of interest paid (and OID accrued, if
any), on the Notes (and the amount of interest withheld for U.S. federal income
taxes, if any) for each calendar year, except as to exempt holders (generally,
holders that are corporations, certain tax-exempt organizations or nonresident
aliens who provide certification as to their status as nonresidents). As long as
the only "Noteholder" of record is Cede, as nominee for DTC, Noteowners and the
IRS will receive tax and other information including the amount of interest paid
on the Notes from Participants and Indirect Participants rather than from the
Indenture Trustee. (The Indenture Trustee, however, will respond to requests for
necessary information to enable Participants, Indirect Participants and certain
other persons to complete their reports.) Each non-exempt Noteowner will be
required to provide, under penalty of perjury, a certificate on IRS Form W-9
containing his or her name, address correct federal taxpayer identification
number and a statement that he or she is not subject to backup withholding.
Should a non-exempt Noteowner fail to provide the required certification, the
Participants or Indirect Participants (or the Paying Agent) will be required to
withhold 31% of the interest (and principal) otherwise payable to the holder,
and remit the withheld amount to the IRS as a credit against the holder's
Federal income tax liability.
 
     Final regulations dealing with backup withholding and information reporting
on income paid to a foreign person and related matters (the "New Withholding
Regulations") were published in the Federal Register on October 14, 1997. In
general, the New Withholding Regulations do not significantly alter the
substantive withholding and information reporting requirements, but do unify
current certification procedures and forms and clarify reliance standards. The
New Withholding Regulations generally will be effective for payments made after
December 31, 1999, subject to certain transition rules. The discussion set forth
above does not take the New Withholding Regulations into account. Prospective
Noteowners are strongly urged to consult their own tax advisor with respect to
the New Withholding Regulations.
 
                            STATE TAX CONSIDERATIONS
 
     The Depositor makes no representations regarding the tax consequences of
purchase, ownership or disposition of the Notes under the tax laws of any state.
Investors considering an investment in the Notes should consult their own tax
advisors regarding such tax consequences.
 
     All investors should consult their own tax advisors regarding the Federal,
state, local, foreign or any other income tax consequences of the purchase,
ownership and disposition of the Notes.

<PAGE>   86
 
                              ERISA CONSIDERATIONS
 
GENERAL
 
     The Employee Retirement Income Security Act of 1974, as amended ("ERISA")
and Section 4975 of the Code impose certain restrictions on employee benefit
plans subject to ERISA or plans or arrangements subject to Section 4975 of the
Code ("Plans") and on persons who are parties in interest or disqualified
persons ("parties in interest") with respect to such Plans. 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 restrictions
of ERISA, and assets of such plans may be invested in the Notes without regard
to the ERISA considerations described below, subject to other applicable Federal
and state law. However, any such governmental or church plan which is qualified
under section 401(a) of the Code and exempt from taxation under section 501(a)
of the Code is subject to the prohibited transaction rules set forth in section
503 of the Code. Any Plan fiduciary which proposes to cause a Plan to acquire
any of the Notes should consult with its counsel with respect to the potential
consequences under ERISA, and the Code, of the Plan's acquisition and ownership
of the Notes. See "ERISA Considerations" in the Prospectus. Investments by Plans
are also 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.
 
PROHIBITED TRANSACTIONS
 
GENERAL
 
     Section 406 of ERISA prohibits parties in interest with respect to a Plan
from engaging in certain transactions (including loans) involving a Plan and its
assets unless a statutory or administrative exemption applies to the
transaction. Section 4975 of the Code imposes certain excise taxes (or, in some
cases, a civil penalty may be assessed pursuant to section 502(i) of ERISA) on
parties in interest which engage in non-exempt prohibited transactions.
 
PLAN ASSET REGULATION
 
     The United States Department of Labor ("Labor") has issued final
regulations concerning the definition of what constitutes the assets of a Plan
for purposes of ERISA and the prohibited transaction provisions of the Code (the
"Plan Asset Regulation"). The Plan Asset Regulation describes the circumstances
under which the assets of an entity in which a Plan invests will be considered
to be "plan assets" such that any person who exercises control over such assets
would be subject to ERISA's fiduciary standards. Under the Plan Asset
Regulation, generally when a Plan invests in another entity, the Plan's assets
do not include, solely by reason of such investment, any of the underlying
assets of the entity. However, the Plan Asset Regulation provides that, if a
Plan acquires an "equity interest" in an entity that is neither a
"publicly-offered security" (as defined therein) nor a security issued by an
investment company registered under the Investment Company Act of 1940, the
assets of the entity will be treated as assets of the Plan investor unless
certain exceptions apply. If the Notes were deemed to be equity interests and no
statutory, regulatory or administrative exemption applies, the Trust could be
considered to hold plan assets by reason of a Plan's investment in the Notes.
Such plan assets would include an undivided interest in any assets held by the
Trust. In such an event, the Indenture Trustee, the Master Servicer or Seller
and other persons, in providing services with respect to the Trust's assets (the
"Transaction Parties"), may be parties in interest with respect to such Plans,
subject to the fiduciary responsibility provisions of Title I of ERISA,
including the prohibited transaction provisions of Section 406 of ERISA, and
Section 4975 of the Code with respect to transactions involving the Trust's
assets. Under the Plan Asset Regulation, the term "equity interest" is defined
as any interest in an entity other than an
                                      S-86
<PAGE>   87
 
instrument that is treated as indebtedness under "applicable local law" and
which has no "substantial equity features." Although the Plan Asset Regulation
is silent with respect to the question of which law constitutes "applicable
local law" for this purpose, Labor has stated that these determinations should
be made under the state law governing interpretation of the instrument in
question. In the preamble to the Plan Asset Regulation, Labor declined to
provide a precise definition of what features are equity features or the
circumstances under which such features would be considered "substantial,"
noting that the question of whether a plan's interest has substantial equity
features is an inherently factual one, but that in making a determination it
would be appropriate to take into account whether the equity features are such
that a Plan's investment in the instrument would be a practical vehicle for the
indirect provision of investment management services. Jeffers, Wilson, Shaff &
Falk, LLP has rendered its opinion that the Notes will be classified as
indebtedness for tax purposes and the Depositor believes that the Notes will be
classified as indebtedness without substantial equity features for ERISA
purposes. However, if the Notes are deemed to be equity interests in the Trust
and no statutory, regulatory or administrative exemption applies, the Trust
could be considered to hold plan assets by reason of a Plan's investment in the
Notes. Furthermore, regardless of whether the Notes are treated as equity for
purposes of ERISA, the acquisition or holding of Notes by or on behalf of a Plan
still could be considered to give rise to a prohibited transaction if a
Transaction Party, or an affiliate thereof, is or becomes a party in interest or
a disqualified person with respect to such Plan.
 
REVIEW BY PLAN FIDUCIARIES
 
     Any Plan fiduciary considering whether to purchase any Notes on behalf of a
Plan should consult with its counsel regarding the applicability of the
fiduciary responsibility and prohibited transaction provisions of ERISA and the
Code to such investment. Among other things, before purchasing any Notes, a
fiduciary of a Plan should make its own determination as to whether the Trust,
as obligor on the Notes, is a party in interest with respect to the Plan, the
availability of the exemptive relief provided in the Plan Asset Regulations and
the availability of any other prohibited transaction exemptions. Purchasers
should analyze whether the decision may have an impact with respect to purchases
of the Notes.
 
                        LEGAL INVESTMENT CONSIDERATIONS
 
     The Notes will constitute "mortgage related securities" for purposes of the
Secondary Mortgage Market Enhancement Act of 1984, as amended ("SMMEA") for so
long as they are rated in one or more of the two highest rating categories by
one or more nationally recognized statistical rating agencies, and, as such, are
legal investments for certain entities to the extent provided in SMMEA. Such
investments, however, will be subject to general regulatory considerations
governing investment practices under state and federal laws.
 
     Moreover, institutions whose investment activities are subject to review by
certain regulatory authorizes may be or may become subject to restrictions,
which may be retroactively imposed by such regulatory authorities, on the
investment by such institutions in certain mortgage related securities. In
addition, several states have adopted or may adopt regulations that prohibit
certain state-chartered institutions from purchasing or holding similar types of
securities.
 
     Accordingly, investors should consult their own legal advisors to determine
whether and to what extent the Notes may be purchased by such investors.
 
     See "Legal Investment Considerations" in the Prospectus.

                                  UNDERWRITING
 
     Subject to the terms and conditions set forth in the underwriting
agreement, dated April 9, 1998 (the "Underwriting Agreement"), between the
Depositor and Bear, Stearns & Co. Inc. (the "Underwriter"), the Depositor has
agreed to sell to the Underwriter and the Underwriter has agreed to purchase
from the Depositor the Notes.
 
     The Notes will be offered by the Underwriter from time to time in
negotiated transaction or otherwise, at varying prices to be determined at the
time of sale. Proceeds to the Depositor, including accrued interest, are
expected to be approximately 99.70% of the aggregate principal balance of the
Notes before deducting issuance expenses payable by the Depositor in connection
with the Notes. In connection with the purchase of the Notes, the Underwriter
may be deemed to have received compensation in the form of underwriting
discounts.
 
     The Depositor has been advised by the Underwriter that it presently intends
to make a market in the Notes offered hereby; however, the Underwriter is not
obligated to do so, any market-making may be discontinued at any time, and there
can be no assurance that an active public market for the Notes will develop.
 
     The Underwriting Agreement provides that the Depositor will indemnify the
Underwriter against certain civil liabilities, including liabilities under the
Securities Act of 1933, as amended.
 
     The Depositor is an affiliate of Bear, Stearns & Co. Inc.
 
                                    EXPERTS
 
     The consolidated balance sheets of Financial Security Assurance Inc. and
Subsidiaries as of December 31, 1998 and December 31, 1997 and the related
consolidated statements of income, changes in shareholder's equity, and cash
flows for each of the three years in the period ended December 31, 1998,
incorporated by reference in this Prospectus Supplement, have been incorporated
herein in reliance on the report of PricewaterhouseCoopers LLP, independent
accountants, given on the authority of that firm as experts in accounting and
auditing.
 
                                 LEGAL MATTERS
 
     Certain legal matters with respect to the Notes will be passed upon for the
Depositor by Brown & Wood LLP, Washington, D.C. and for the Underwriter by Brown
& Wood LLP, Washington, D.C. Certain legal matters will be passed upon for the
Seller and its affiliates by Tobin & Tobin, a professional corporation, San
Francisco, California. Certain federal income tax consequences with respect to
the Notes will be passed upon by Jeffers, Wilson, Shaff & Falk, LLP, Irvine,
California.
 
                                    RATINGS
 
     It is a condition to issuance that the Notes be rated "AAA" by S&P and
"Aaa" by Moody's.
 
     A securities rating addresses the likelihood of the receipt by Noteholders
of payments on the Mortgage Loans. The rating takes into consideration the
characteristics of the Mortgage Loans and the structural, legal and tax aspects
associated with the Notes. The ratings on the Notes do not, however, constitute
statements regarding the likelihood or frequency of prepayments on the Mortgage
Loans or the possibility that Noteholders might realize a lower than anticipated
yield.
 
     The ratings assigned to the Notes will depend primarily upon the
creditworthiness of the Note Insurer. Any reduction in a rating assigned to the
financial strength of the Insurer below the ratings
 
                                      S-88
<PAGE>   89
 
initially assigned to the Notes may result in a reduction of one or more of the
ratings assigned to the Notes.
 
     A securities 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
organization. Each securities rating should be evaluated independently of
similar ratings on different securities. The ratings do not address the
likelihood of the payment of any LIBOR Carryover Amount or any Supplemental
Interest Payment.
 
     There can be no assurance as to whether any other rating agency will rate
the Notes or, if it does, what rating would be assigned by such other rating
agency. The rating assigned by such other rating agency to the Notes could be
lower than the respective ratings assigned by the applicable Rating Agency.

                                    ANNEX A
 
         GLOBAL CLEARANCE, SETTLEMENT AND TAX DOCUMENTATION PROCEDURES
 
     Except in certain limited circumstances, the globally offered
Mortgage-Backed LIBOR Notes, Series 1999-1 (the "Global Securities"), will be
available only in book-entry form. Investors in the Global Securities may hold
such Global Securities through DTC, Cedel or Euroclear. The Global Securities
will be traceable as home market instruments in both the European and U.S.
domestic markets. Initial settlement and all secondary trades will settle in
same-day funds.
 
     Secondary market trading between investors holding Global Securities
through Cedel and Euroclear will be conducted in the ordinary way in accordance
with their normal rules and operating procedures and in accordance with
conventional eurobond practice (i.e., seven calendar day settlement).
 
     Secondary market trading between investors holding Global Securities
through DTC will be conducted according to the rules and procedures applicable
to U.S. corporate debt obligations.
 
     Secondary cross-market trading between participants of Cedel or Euroclear
and Participants holding Notes will be effected on a delivery-against-payment
basis through the Relevant Depositaries of Cedel and Euroclear (in such
capacity) and as Participants.
 
     Non-U.S. holders (as described below) of Global Securities will be subject
to U.S. withholding taxes unless such holders meet certain requirements and
deliver appropriate U.S. tax documents to the securities clearing organizations
or their participants.
 
INITIAL SETTLEMENT
 
     All Global Securities will be held in book-entry form by DTC in the name of
Cede, as nominee of DTC. Investors' interests in the Global Securities will be
represented through financial institutions acting on their behalf as direct and
indirect participants in DTC. As a result, Cedel and Euroclear will hold
positions on behalf of their participants through their Relevant Depositaries,
which in turn will hold such positions in accounts as Participants.
 
     Investors selecting to hold their Global Securities through DTC will follow
DTC settlement practice. Investor securities custody accounts will be credited
with their holdings against payment in same-day funds on the settlement date.
 
     Investors electing to hold their Global Securities through Cedel or
Euroclear accounts will follow the settlement procedures applicable to
conventional eurobonds, except that there will be no temporary global security
and no "lock-up" or restricted period. Global Securities will be credited to
securities custody accounts on the settlement date against payment in same-day
funds.
 
SECONDARY MARKET TRADING
 
     Because the purchaser determines the place of delivery, it is important to
establish at the time of the trade where both the purchaser's and seller's
accounts are located to ensure that settlement can be made on the desired value
date.
 
     TRADING BETWEEN PARTICIPANTS.  Secondary market trading between
Participants will be settled using the procedures applicable to prior
asset-backed Note issues in same-day funds.
 
     TRADING BETWEEN CEDEL AND/OR EUROCLEAR PARTICIPANTS.  Secondary market
trading between Cedel Participants or Euroclear Participants will be settled
using the Procedures applicable to conventional eurobonds in same-day funds.
 
                                       A-1
<PAGE>   94
 
     TRADING BETWEEN DTC SELLER AND CEDEL OR EUROCLEAR PARTICIPANTS.  When
Global Securities are to be transferred from the account of a Participant to the
account of a Cedel Participant or a Euroclear Participant, the purchaser will
send instructions to Cedel or Euroclear through a Cedel Participant or Euroclear
Participant at least one Business Day prior to settlement. Cedel or Euroclear
will instruct the respective Depositary, as the case may be, to receive the
Global Securities against payment. Payment will include interest accrued on the
Global Securities from and including the last coupon payment date to and
excluding the settlement date, on the basis of the actual number of days in such
accrual period and a year assumed to consist of 360 days. For transactions
settling on the 31st of the month, payment will include interest accrued to and
excluding the first day of the following month. Payment will then be made by the
respective Depositary to the Participant's account against delivery of the
Global Securities. After settlement has been completed, the Global Securities
will be credited to the respective clearing system and by the clearing system,
in accordance with its usual procedures, to the Cedel Participant's or Euroclear
Participant's account. The securities credit will appear the next day (European
time) and the cash debt will be back-valued to, and the interest on the Global
Securities will accrue from, the value date (which would be the preceding day
when settlement occurred in New York). If settlement is not completed on the
intended value date (i.e., the trade fails), the Cedel or Euroclear cash debt
will be valued instead as of the actual settlement date.
 
     Cedel Participants and Euroclear Participants will need to make available
to the respective clearing systems the funds necessary to process same-day funds
settlement. The most direct means of doing so is to preposition funds for
settlement, either from cash on hand or existing lines of credit, as they would
for any settlement occurring within Cedel or Euroclear. Under this approach,
they may take on credit exposure to Cedel or Euroclear until the Global
Securities are credited to their accounts one day later.
 
     As an alternative, if Cedel or Euroclear has extended a line of credit to
them, Cedel Participants or Euroclear Participants can elect not to preposition
funds and allow that credit line to be drawn upon to finance settlement. Under
this procedure, Cedel Participants or Euroclear Participants purchasing Global
Securities would incur overdraft charges for one day, assuming they clear the
overdraft when the Global Securities are credited to their accounts. However,
interest on the Global Securities would accrue from the value date. Therefore,
in many cases the investment income on the Global Securities earned during that
one-day period may substantially reduce or offset the amount of such overdraft
charges, although this result will depend on each Cedel Participant's or
Euroclear Participant's particular cost of funds.
 
     Because the settlement is taking place during New York business hours,
Participants can employ their usual procedures for sending Global Securities to
the respective European Depositary for the benefit of Cedel Participants or
Euroclear Participants. The sale proceeds will be available to the DTC seller on
the settlement date. Thus, to the Participants a cross-market transaction will
settle no differently than a trade between two Participants.
 
     TRADING BETWEEN CEDEL OR EUROCLEAR SELLER AND DTC PURCHASER.  Due to time
zone differences in their favor, Cedel Participants and Euroclear Participants
may employ their customary procedures for transactions in which Global
Securities are to be transferred by the respective clearing system, through the
respective Depositary, to a Participant. The seller will send instructions to
Cedel or Euroclear through a Cedel Participant or Euroclear Participant at least
one Business Day prior to settlement. In these cases, Cedel or Euroclear will
instruct the Relevant Depositary, as appropriate, to deliver the Global
Securities to the Participant's account against payment. Payment will include
interest accrued on the Global Securities from and including the last coupon
payment to and excluding the settlement date on the basis of the actual number
of days in such accrual period and a year assumed to consist of 360 days. For
transactions settling on the 31st of the month, payment will
 
                                       A-2
<PAGE>   95
 
include interest accrued to and excluding the first day of the following month.
The payment will then be reflected in the account of the Cedel Participant or
Euroclear Participant the following day, and receipt of the cash proceeds in the
Cedel Participant's or Euroclear Participant's account would be back-valued to
the value date (which would be the preceding day, when settlement occurred in
New York). Should the Cedel Participant or Euroclear Participant have a line of
credit with its respective clearing system and elect to be in debt in
anticipation of receipt of the sale proceeds in its account, the back valuation
will extinguish any overdraft incurred over that one-day period. If settlement
is not completed on the intended value date (i.e., the trade fails), receipt of
the cash proceeds in the Cedel Participant's or Euroclear Participant's account
would instead be valued as of the actual settlement date.
 
     Finally, day traders that use Cedel or Euroclear and that purchase Global
Securities from Participants for delivery to Cedel Participants or Euroclear
Participants should note that these trades would automatically fail on the sale
side unless affirmative action were taken. At least three techniques should be
readily available to eliminate this potential problem:
 
     (a) borrowing through Cedel or Euroclear for one day (until the purchase
side of the day trade is reflected in their Cedel or Euroclear accounts) in
accordance with the clearing system's customary procedures;
 
     (b) borrowing the Global Securities in the U.S. from a Participant no later
than one day prior to settlement, which would give the Global Securities
sufficient time to be reflected in their Cedel or Euroclear account in order to
settle the sale side of the trade; or
 
     (c) staggering the value dates for the buy and sell sides of the trade so
that the value date for the purchase from the Participant is at least one day
prior to the value date for the sale to the Cedel Participant or Euroclear
Participant.
 
CERTAIN U.S. FEDERAL INCOME TAX DOCUMENTATION REQUIREMENTS
 
     A beneficial owner of Global Securities holding securities through Cedel or
Euroclear (or through DTC if the holder has an address outside the U.S.) will be
subject to the 30% U.S. withholding tax that generally applies to payments of
interest (including original issue discount) on registered debt issued by U.S.
Persons, unless (i) each clearing system, bank or other financial institution
that holds customers' securities in the ordinary course of its trade or business
in the chain of intermediaries between such beneficial owner and the U.S. entity
required to withhold tax complies with applicable certification requirements and
(ii) such beneficial owner takes one of the following steps to obtain an
exemption or reduced tax rate:
 
     EXEMPTION FOR NON-U.S. PERSONS (FORM W-8).  Beneficial owners of Global
Securities that are Non-U.S. Persons can obtain a complete exemption from the
withholding tax by filing a signed Form W-8 (Certificate of Foreign Status). If
the information shown on Form W-8 changes, a new Form W-8 must be filed within
30 days of such change.
 
     EXEMPTION FOR NON-U.S. PERSONS WITH EFFECTIVELY CONNECTED INCOME (FORM
4224).  A non-U.S. Person, including a non-U.S. corporation or bank with a U.S.
branch, for which the interest income is effectively connected with its conduct
of a trade or business in the United States, can obtain an exemption from the
withholding tax by filing Form 4224 (Exemption from Withholding of Tax on Income
Effectively Connected with the Conduct of a Trade of Business in the United
States).
 
     EXEMPTION OR REDUCED RATE FOR NON-U.S. PERSONS RESIDENT IN TREATY COUNTRIES
(FORM 1001). Non-U.S. Persons residing in a country that has a tax treaty with
the United States can obtain an exemption or reduced tax rate depending on the
treaty terms) by filing Form 1001 (Ownership, Exemption or Reduced Rate
Certificate). If the treaty provides only for a reduced rate, withholding
 
                                       A-3
<PAGE>   96
 
tax will be imposed at that rate unless the filer alternatively files Form W-8.
Form 1001 may be filed by the beneficial owners or their agents.
 
     EXEMPTION FOR U.S. PERSONS (FORM W-9).  U.S. Persons can obtain a complete
exemption from the withholding tax by filing Form W-9 (Payer's Request for
Taxpayer Identification Number and Certification).
 
     U.S. FEDERAL INCOME TAX REPORTING PROCEDURE.  The beneficial owner of a
Global Security or, in the case of a Form 1001 or a Form 4224 filer, his agent,
files by submitting the appropriate form to the person through whom it holds
(the clearing agency, in the case of persons holding directly on the books of
the clearing agency). Form W-8 and Form 1001 are effective for three calendar
years, and Form 4224 is effective for one calendar year.
 
     The term "U.S. Person" means (i) a citizen or resident of the United
States, (ii) a corporation or partnership organized in or under the laws of the
United States or any political subdivision thereof, (iii) an estate that is
subject to United States federal income tax, regardless of the source of its
income or (iv) a trust if (a) a court in the United States is able to exercise
primary supervision over the administration of the trust, and (b) one or more
United States persons have the authority to control all substantial decisions of
the trust. The term "Non-U.S. Person" means any person who is not a U.S. Person.
This summary does not deal with all aspects of U.S. federal income tax
withholding that may be relevant to foreign holders of Global Securities or with
the application of recently issued Treasury Regulations relating to tax
documentation requirements that are generally effective with respect to payments
made after December 31, 1999. Investors are advised to consult their own tax
advisors for specific tax advice concerning their holding and disposing of
Global Securities.

at the times, at the rates, in the amounts and in the order of priority set
forth in the related Prospectus Supplement.
 
     If a Series includes multiple Classes, such Classes may vary with respect
to the amount, percentage and timing of distributions of principal, interest or
both and one or more Classes may be subordinated to other Classes with respect
to distributions of principal, interest or both as described herein and in the
related Prospectus Supplement. If so specified in the related Prospectus
Supplement, the Primary Assets and other assets comprising the Trust Fund may be
divided into one or more Asset Groups and each Class of the related Series will
evidence beneficial ownership of the corresponding Asset Group, as applicable.
 
     The rate of reduction of the aggregate principal balance of each Class of a
Series may depend upon the rate of payment (including prepayments) with respect
to the Loans or, in the case of Private Securities, Underlying Loans, as
applicable. In such a case, a rate of prepayment lower or higher than
anticipated will affect the yield on the Securities of a Series in the manner
described herein and in the related Prospectus Supplement. Under certain limited
circumstances described herein and in the related Prospectus Supplement, a
Series of Securities may be subject to termination or redemption under the
circumstances described herein and in the related Prospectus Supplement.
 
     If specified in the related Prospectus Supplement, an election may be made
to treat certain assets comprising the Trust Fund for a Series as a "real estate
mortgage investment conduit" (a "REMIC") for federal income tax purposes. See
"Certain Federal Income Tax Considerations" herein.

     Periodic and annual reports concerning the related Trust Fund for a Series
of Securities are required under the related Agreement to be forwarded to
Holders. Unless otherwise specified in the related Prospectus Supplement, such
reports will not be examined and reported on by an independent public

PRINCIPAL PAYMENTS.........  All payments of principal of a Series of Securities
                             will be made in an aggregate amount determined as
                             set forth in the related Prospectus Supplement, and
                             will be paid at the times, allocated among the
                             Classes of such Series in the order and amounts and

                             specified in the related Prospectus Supplement.
 
FINAL SCHEDULED
DISTRIBUTION DATE OF THE
SECURITIES.................  The Final Scheduled Distribution Date with respect
                             to (i) each Class of Notes is the date not later
                             than which principal of the Notes will be fully
                             paid and (ii) each Class of Certificates is the
                             date after which no Certificates of such Class are
                             expected to remain outstanding, in each case
                             calculated on the basis of the assumptions
                             applicable to such Series described in the related
                             Prospectus Supplement. The Final Scheduled
                             Distribution Date of a Class may equal the maturity
                             date of the Primary Asset in the related Trust Fund
                             that has the latest stated maturity, or will be
                             determined as described herein and in the related
                             Prospectus Supplement.
 
                             The actual final Distribution Date of the
                             Securities of a Series will, to the extent
                             described in the related Prospectus Supplement,
                             depend upon the rate of payment (including
                             prepayments, liquidations due to default, the
                             receipt of proceeds from casualty Insurance
                             Policies and repurchases) of the Loans or
                             Underlying Loans relating to the Private
                             Securities, as applicable, in the related Trust
                             Fund. Unless otherwise specified in the related
                             Prospectus Supplement, the actual final
                             Distribution Date of any Security is likely to
                             occur earlier and may occur substantially earlier
                             or may occur later than its Final Scheduled
                             Distribution Date as a result of the application of
                             prepayments to the reduction of the principal
                             balances of the Securities and as a result of
                             defaults on the Primary Assets. The rate of
                             payments on the Loans or Underlying Loans relating
                             to the Private Securities, as applicable, in the
                             Trust Fund for a Series will depend on a variety of
                             factors, including certain characteristics of such
                             Loans or Underlying Loans, as applicable, and the
                             prevailing level of interest rates from time to
                             time, as well as on a variety of economic,
                             demographic, tax, legal, social and other factors.
                             No assurance can be given as to the actual
                             prepayment experience with respect to a Series. See
                             "Risk Factors -- Yield May Vary" and "Description
                             of the Securities -- Weighted Average Life of the
                             Securities" herein.
 
OPTIONAL TERMINATION.......  One or more Classes of Securities of any Series may
                             be redeemed or repurchased in whole or in part, at
                             the Depositor's or the Servicer's option, at such
                             time and under the circumstances specified in the
                             related Prospectus Supplement, at the price set
                             forth therein. If so specified in the related
                             Prospectus Supplement for a Series of Securities,
                             the Depositor, the Servicer or such other entity
                             that is specified in the related Prospectus
                             Supplement may, at its option, cause an early
                             termination of the related Trust Fund by
                             repurchasing all of the Primary Assets remaining in
                             the Trust Fund on or after a specified date, or on
                             or after such time as the aggregate principal
                             balance of the Securities of the Series or the
                             Primary Assets relating to such Series, as
                             specified in the related Prospectus Supplement, is
                             less than the amount or percentage specified in the
                             related Prospectus Supplement. See "Description of
                             the Securities -- Optional Redemption, Purchase or
                             Termination."

                             In addition, the related Prospectus Supplement may
                             provide other circumstances under which Holders of
                             Securities of a Series could be fully paid
                             significantly earlier than would otherwise be the
                             case if payments or distributions were solely based
                             on the activity of the related Primary Assets.
 
THE TRUST FUND.............  The Trust Fund for a Series of Securities will
                             consist of one or more of the assets described
                             below, as described in the related Prospectus
                             Supplement.

                             to make certain payments, as provided in the
                             related Prospectus Supplement. See

FEDERAL INCOME TAX
 CONSIDERATIONS
 
A. DEBT SECURITIES AND
REMIC RESIDUAL
 SECURITIES................  If (i) an election is made to treat all or a
                             portion of a Trust Fund for a Series as a "real
                             estate mortgage investment conduit" (a "REMIC") or
                             (ii) so provided in the related Prospectus
                             Supplement, a Series of Securities will include one
                             or more Classes of taxable debt obligations under
                             the Internal Revenue Code of 1986, as amended (the
                             "Code"). Stated interest with respect to such
                             Classes of Securities will be reported by the
                             related Holder in accordance with such Holder's
                             method of accounting except that, in the case of
                             Securities constituting "regular interests" in a
                             REMIC ("Regular Interests"), such interest will be
                             required to be reported on the accrual methods
                             regardless of such Holder's usual method of
                             accounting. Securities that are Compound Interest
                             Securities, Zero Coupon Securities or Interest Only
                             Securities will, and certain other Classes of
                             Securities may, be issued with original issue
                             discount that is not de minimis. In such cases, the
                             related Holder will be required to include original
                             issue discount in gross income as it accrues, which
                             may be prior to the receipt of cash attributable to
                             such income. If a Security is issued at a premium,
                             such Holder may be entitled to make an election to
                             amortize such premium on a constant yield method.
 
                             In the case of a REMIC election, a Class of
                             Securities may be treated as a REMIC "residual
                             interest" (each, a "Residual Interest"). A Holder
                             of a Residual Interest will be required to include
                             in its income its pro rata share of the taxable
                             income of the REMIC. In certain circumstances, the
                             Holder of a Residual Interest may have REMIC
                             taxable income or tax liability attributable to
                             REMIC taxable income for a particular period in
                             excess of cash distributions for such period or
                             have an after-tax return that is less than the
                             after-tax return on comparable debt instruments. In
                             addition, a portion (or, in some cases, all) of the
                             income from a Residual Interest (i) may not be
                             subject to offset by losses from other activities
                             or investments, (ii) for a Holder that is subject
                             to tax under the Code on unrelated business taxable
                             income, may be treated as unrelated business
                             taxable income and (iii) for a foreign Holder, may
                             not qualify for exemption from or reduction of
                             withholding. In addition, (i) Residual Interests
                             are subject to transfer restrictions and (ii)
                             certain transfers of Residual Interests will not be
                             recognized for federal income tax purposes.
                             Further, individual Holders are subject to
                             limitations on the deductibility of expenses of the
                             REMIC. See "Certain Federal Income Tax
                             Considerations."
 
B. NON-REMIC PASS-THROUGH
 SECURITIES................  If so specified in the related Prospectus
                             Supplement, the Trust Fund for a Series will be
                             treated as a grantor trust and will not be

C. OWNER TRUST
SECURITIES.................  If so specified in the Prospectus Supplement, the
                             Trust Fund will be treated as a partnership for
                             purposes of federal and state income tax. Each
                             Noteholder, by the acceptance of a Note of a given
                             Series, will agree to treat such Note as
                             indebtedness; and each Certificateholder, by the
                             acceptance of a Certificate of a given Series, will
                             agree to treat the related Trust Fund as a
                             partnership in which such Certificateholder is a
                             partner for federal income and state tax purposes.
                             Alternative characterizations of such Trust Fund
                             and such Certificates are possible, but would not
                             result in materially adverse tax consequences to
                             Certificateholders. See "Certain Federal Income Tax

ERISA CONSIDERATIONS.......  A fiduciary of any employee benefit plan or other
                             retirement plan or arrangement subject to the
                             Employee Retirement Income Security Act of 1974, as
                             amended ("ERISA"), or the Code should carefully
                             review with its own legal advisors whether the
                             purchase or holding of Securities could give rise
                             to a transaction prohibited or otherwise
                             impermissible under ERISA or the Code. Certain
                             Classes of Securities may not be transferred unless
                             the applicable Trustee and the Depositor are
                             furnished with a letter of representation or an
                             opinion of counsel to the effect that such transfer
                             will not result in a violation of the prohibited
                             transaction provisions of ERISA and the Code and
                             will not subject the applicable Trustee, the
                             Depositor or the Servicer to additional
                             obligations. See "Description of the
                             Securities -- General" and "ERISA Considerations."
 
LEGAL INVESTMENT...........  Unless otherwise specified in the related
                             Prospectus Supplement, Securities of each Series
                             offered by this Prospectus and the related
                             Prospectus Supplement will not constitute "mortgage
                             related securities" under the Secondary Mortgage
                             Market Enhancement Act of 1984, as amended
                             ("SMMEA"). Investors whose investment authority is
                             subject to legal restrictions should consult their
                             own legal advisors to determine whether and to what
                             extent the Securities constitute legal investments
                             for them. See "Legal Investment."
 
USE OF PROCEEDS............  The Depositor will use the net proceeds from the
                             sale of each Series for one or more of the
                             following purposes: (i) to purchase the related
                             Primary Assets, (ii) to repay indebtedness incurred
                             to obtain funds to acquire such Primary Assets,
                             (iii) to establish any Reserve Funds described in
                             the related Prospectus Supplement and (iv) to pay
                             costs of structuring and issuing such Securities,
                             including the costs of obtaining Enhancement, if
                             any. If so specified in the related Prospectus
                             Supplement, the purchase of the Primary Assets for
                             a Series will be effected by an exchange of
                             Securities with the Seller of such Primary Assets.
                             See "Use of Proceeds."
 
RATINGS....................  It will be a requirement for issuance of any Series
                             that the Securities offered by this Prospectus and
                             the related Prospectus Supplement be rated by at
                             least one Rating Agency in one of its four highest
                             applicable
                                       13

                             rating categories. The rating or ratings applicable
                             to Securities of each Series offered hereby and by
                             the related Prospectus Supplement will be as set
                             forth in the related Prospectus Supplement. A
                             securities rating should be evaluated independently
                             of similar ratings on different types of
                             securities. A securities rating is not a
                             recommendation to buy, hold or sell securities, and
                             does not address the effect that the rate of
                             prepayments on Loans or Underlying Loans relating
                             to Private Securities, as applicable, for a Series
                             may have on the yield to investors in the
                             Securities of such Series. See "Risk
                             Factors -- Ratings Are Not Recommendations."

<PAGE>   111
 
                                  RISK FACTORS
 
     Investors should consider, among other things, the following factors in
connection with the purchase of the Securities.
 
     No Secondary Market.  There will be no market for the Securities of any
Series prior to the issuance thereof, and there can be no assurance that a
secondary market will develop or, if it does develop, that it will provide
Holders with liquidity of investment or will continue for the life of the
Securities of such Series. The underwriter(s) specified in the related
Prospectus Supplement (the "Underwriters") expect to make a secondary market in
the related Securities, but will have no obligation to do so.
 
     Primary Assets Are Only Source of Repayment.  The Depositor does not have,
nor is it expected to have, any significant assets. The Securities of a Series
will be payable solely from the assets of the Trust Fund for such Securities.
There will be no recourse to the Depositor or any other person for any default
on or any failure to receive distributions on the Securities. Further, unless
otherwise stated in the related Prospectus Supplement, at the times set forth in
such Prospectus Supplement, certain Primary Assets and/or any balance remaining
in the Collection Account or Distribution Account(s) immediately after making
all payments due on the Securities of such Series and other payments specified
in Securities Prospectus Supplement, may be promptly released or remitted to the
Depositor, the Servicer, the Enhancer or any other person entitled thereto, and
will no longer be available for making payments to Holders. Consequently,
Holders of Securities of each Series must rely solely upon payments with respect
to the Primary Assets and the other assets constituting the Trust Fund for a
Series of Securities, including, if applicable, any amounts available pursuant
to any Enhancement for such Series, for the payment of principal of and interest
on the Securities of such Series.
 
     Holders of Notes will be required under the Indenture to proceed only
against the Primary Assets and other assets constituting the related Trust Fund
in the case of a default with respect to such Notes and may not proceed against
any assets of the Depositor. There is no assurance that the market value of the
Primary Assets or any other assets for a Series will at any time be equal to or
greater than the aggregate principal amount of the Securities of such Series
then outstanding, plus accrued interest thereon. Moreover, upon an Event of
Default under the Indenture for a Series of Notes and a sale of the assets in
the Trust Fund or upon a sale of the assets of a Trust Fund for a Series of
Certificates, the Trustee under the related Indenture (the "Indenture Trustee"),
the Servicer, if any, the Enhancer and any other service provider specified in
the related Prospectus Supplement generally will be entitled to receive the
proceeds of any such sale to the extent of unpaid fees and other amounts owing
to such persons under the related Agreement prior to distributions to Holders of
Securities. Upon any such sale, the proceeds thereof may be insufficient to pay
in full the principal of and interest on the Securities of such Series.
 
     The only obligations, if any, of the Depositor with respect to the
Securities of any Series will be pursuant to certain representations and
warranties. See "The Agreements -- Assignment of Primary Assets" herein. The
Depositor does not have, and is not expected in the future to have, any
significant assets with which to meet any obligation to repurchase Primary
Assets with respect to which there has been a breach of any representation or
warranty. If, for example, the Depositor were required to repurchase a Primary
Asset, its only source of funds from which to make such repurchase would be from
funds obtained from the enforcement of a corresponding obligation, if any, on
the part of the originator of the Primary Assets, the Servicer or the Seller, as
the case may be, or from a Reserve Fund established to provide funds for such
repurchases.
 
     Limited Protection Against Losses.  Although any Enhancement is intended to
reduce the risk of delinquent payments or losses to Holders of Securities
entitled to the benefit thereof, the amount of such Enhancement will be limited,
as set forth in the related Prospectus Supplement, and will decline and could be
depleted under certain circumstances prior to the payment in full of the related
Series of Securities, and as a result, Holders may suffer losses. See
"Enhancement."
 
     Yield May Vary; Subordination.  The yield to maturity experienced by a
Holder of Securities may be affected by the rate of payment of principal of the
Loans or Underlying Loans relating to the Private Securities, as applicable. The
timing of principal payments on the Securities of a Series will be affected by a
number of factors, including the following: (i) the extent of prepayments of the
Loans or Underlying Loans
 
                                       15
<PAGE>   112
 
relating to the Private Securities, as applicable, which prepayments may be
influenced by a variety of factors; (ii) the manner of allocating principal
payments among the Classes of Securities of a Series as specified in the related
Prospectus Supplement; (iii) the exercise by the party entitled thereto of any
right of optional termination; and (iv) in the case of Trust Funds comprised of
Revolving Credit Line Loans, any provisions in the related Agreement described
in the applicable Prospectus Supplement respecting any non-amortization, early
amortization or scheduled amortization period. See "Description of the
Securities -- Weighted Average Life of Securities." Prepayments may also result
from repurchases of Loans or Underlying Loans, as applicable, due to material
breaches of the Seller's or the Depositor's warranties.
 
     Interest payable on the Securities of a Series on a Distribution Date will
include all interest accrued during the period specified in the related
Prospectus Supplement. In the event interest accrues during the calendar month
prior to a Distribution Date, the effective yield to Holders will be reduced
from the yield that would otherwise be obtainable if interest payable on the
Security were to accrue through the day immediately preceding each Distribution
Date, and the effective yield (at par) to Holders will be less than the
indicated coupon rate. See "Description of the Securities -- Payments of
Interest."
 
     The rights of Subordinated Securityholders to receive distributions to
which they would otherwise be entitled with respect to the Trust Fund will be
subordinate to the rights of the Servicer and the Holders of Senior Securities,
to the extent described in the related Prospectus Supplement. As a result of the
foregoing, investors must be prepared to bear the risk that they may be subject
to delays in payment and may not recover their initial investments in the
Subordinated Securities.
 
     Balloon Payments.  Certain of the Loans as of the related Cut-off Date may
not be fully amortizing over their terms to maturity, and thus will require
substantial principal payments (i.e., balloon payments) at their stated
maturity. Loans with balloon payments involve a greater degree of risk because
the ability of a borrower to make a balloon payment typically will depend upon
such borrower's ability either to timely refinance the related Loan or to timely
sell the related Property. The ability of a borrower to accomplish either of
these goals will be affected by a number of factors, including the level of
available mortgage rates at the time of sale or refinancing, the borrower's
equity in the related Property, the financial condition of the borrower and tax
laws. Losses on such Loans that are not otherwise covered by the credit
enhancement described in the applicable Prospectus Supplement will be borne by
the Holders of one or more Classes of Securities of the related Series.
 
     Property Values May Be Insufficient.  If the Mortgage Loans in a Trust Fund
are primarily junior liens subordinate to the rights of the mortgagee under the
related senior mortgage or mortgages, the proceeds from any liquidation,
insurance or condemnation proceedings will be available to satisfy the
outstanding balance of such junior mortgage only to the extent that the claims
of such senior mortgagees have been satisfied in full, including any related
foreclosure costs. In addition, a junior mortgagee may not foreclose on the
Property securing a junior mortgage unless it forecloses subject to the senior
mortgages, in which case it must either pay the entire amount due on the senior
mortgages to the senior mortgagees at or prior to the foreclosure sale or
undertake the obligation to make payments on the senior mortgages in the event
the mortgagor is in default thereunder. The Trust Fund will not have any source
of funds to satisfy the senior mortgages or make payments due to the senior
mortgagees.
 
     There are several factors that could adversely affect the value of
Properties such that the outstanding balance of the related Loan, together with
any senior financing on the Properties, would equal or exceed the value of the
Properties. Among the factors that could adversely affect the value of the
Properties are an overall decline in the residential real estate market in the
areas in which the Properties are located or a decline in the general condition
of the Properties as a result of failure of borrowers to maintain adequately the
Properties or of natural disasters that are not necessarily covered by
insurance, such as earthquakes and floods. Any such decline could extinguish the
value of a junior interest in a Property before having any effect on the related
senior interest therein. If such a decline occurs, the actual rates of
delinquencies, foreclosure and losses on the junior Loans could be higher than
those currently experienced in the mortgage lending industry in general.
 
     Risks relating to Certain Geographic Regions where Mortgage Loans may be
Concentrated. Certain geographic regions of the United States from time to time
will experience weaker regional economic conditions and housing markets, and,
consequently, will experience higher rates of loss and delinquency than will be
experienced on mortgage loans generally. The Mortgage Loans underlying certain
Series of Securities
                                       16
<PAGE>   113
 
may be concentrated in these regions, and such concentration may present risk
considerations in addition to those generally present for similar
mortgage-backed securities without such concentration.
 
     Book-Entry Registration.  If Securities are issued in book-entry form, such
registration may reduce the liquidity of such Securities in the secondary
trading market, since investors may be unwilling to purchase Securities for
which they cannot obtain physical certificates. Since transactions in book-entry
Securities can be effected only through the Depository Trust Company ("DTC"),
participating organizations, Financial Intermediaries and certain banks, the
ability of a Holder to pledge a book-entry Security to persons or entities that
do not participate in the DTC system may be limited due to lack of a physical
certificate representing such Securities. Security Owners will not be recognized
as Holders as such term is used in the related Agreement, and Security Owners
will be permitted to exercise the rights of Holders only indirectly through DTC
and its Participants.
 
     In addition, Holders may experience some delay in their receipt of
distributions of principal of and interest on book-entry Securities, since
distributions are required to be forwarded by the applicable Trustee to DTC and
DTC will then be required to credit such distributions to the accounts of
Depository participants, which thereafter will be required to credit them to the
accounts of Holders either directly or indirectly through Financial
Intermediaries.
 
     Pre-Funding May Adversely Affect Investment.  If a Trust Fund includes a
Pre-Funding Account and the Principal Balance of additional Loans delivered to
the Trust Fund during the Pre-Funding Period is less than the original
Pre-Funded Amount, the Holders of the Securities of the related Series will
receive a prepayment of principal as and to the extent described in the related
Prospectus Supplement. Any such principal prepayment may adversely affect the
yield to maturity of the applicable Securities. Since prevailing interest rates
are subject to fluctuation, there can be no assurance that investors will be
able to reinvest such a prepayment at yields equaling or exceeding the yields on
the related Securities. It is possible that the yield on any such reinvestment
will be lower, and may be significantly lower, than the yield on the related
Securities.
 
     The ability of a Trust Fund to invest in subsequent Loans during the
related Pre-Funding Period will be dependant on the ability of the Seller to
originate or acquire Loans that satisfy the requirements for transfer to the
Trust Fund. The ability of the Seller to originate or acquire such Loans will be
affected by a variety of social and economic factors, including the prevailing
level of market interest rates, unemployment levels and consumer perceptions of
general economic conditions.
 
     Although subsequent Loans must satisfy the characteristics described in the
related Prospectus Supplement and generally must be selected on the basis of the
same criteria as those used to select the initial Loans, such Loans may have
been originated more recently than the Loans originally transferred to the Trust
Fund and may be of a lesser credit quality. As a result, the addition of
subsequent Loans may adversely affect the performance of the related Securities.
 
     Bankruptcy Risks.  Federal and state statutory provisions, including the
federal bankruptcy laws and state laws affording relief to debtors, may
interfere with or affect the ability of the secured mortgage lender to realize
upon its security. For example, in a proceeding under the federal Bankruptcy
Code, a lender may not foreclose on a mortgaged property without the permission
of the bankruptcy court. The rehabilitation plan proposed by the related debtor
may provide, if the mortgaged property is not the debtor's principal residence
and the court determines that the value of the mortgaged property is less than
the principal balance of the related mortgage loan, for the reduction of the
secured indebtedness to the value of the mortgaged property as of the date of
the commencement of the bankruptcy, rendering the lender a general unsecured
creditor for the difference, and also may reduce the monthly payments due under
such mortgage loan, change the rate of interest and alter the mortgage loan
repayment schedule. The effect of any such proceedings under the federal
Bankruptcy Code, including but not limited to any automatic stay, could result
in delays in receiving payments on the Loans underlying a Series of Securities
and possible reductions in the aggregate amount of such payments.
 
     Consequences of Owning Original Issue Discount Securities. Debt Securities
that are Compound Interest Securities will be, and certain of the Debt
Securities may be, issued with original issue discount for federal income tax
purposes. A Holder of Debt Securities issued with original issue discount will
be required to
 
                                       17
<PAGE>   114
 
include original issue discount in ordinary gross income for federal income tax
purposes as it accrues, in advance of receipt of the cash attributable to such
income. Accrued but unpaid interest on the Debt Securities that are Compound
Interest Securities generally will be treated as having original issue discount
for this purpose. See "Certain Federal Income Tax Considerations -- Interest and
Acquisition Discount" herein.
 
     REMIC-Related Risks.  Holders of Residual Interest Securities will be
required to report on their federal income tax returns as ordinary income their
pro rata share of the taxable income of the REMIC, regardless of the amount or
timing of their receipt of cash payments, as described in "Certain Federal
Income Tax Considerations." Accordingly, under certain circumstances, Holders of
Securities that constitute Residual Interest Securities may have taxable income
and tax liabilities arising from such investment during a taxable year in excess
of the cash received during such period. Individual Holders of Residual Interest
Securities may be limited in their ability to deduct servicing fees and other
expenses of the REMIC. In addition, Residual Interest Securities are subject to
certain restrictions on transfer. Because of the special tax treatment of
Residual Interest Securities, the taxable income arising in a given year on a
Residual Security will not be equal to the taxable income associated with
investment in a corporate bond or stripped instrument having similar cash flow
characteristics and pre-tax yield. Therefore, the after-tax yield on the
Residual Interest Security may be significantly less than that of a corporate
bond or stripped instrument having similar cash flow characteristics.
Additionally, prospective purchasers of a REMIC Residual Interest Security
should be aware that the IRS recently finalized regulations that provide that a
REMIC Residual Interest Security acquired after January 3, 1995 cannot be
marked-to-market. Prospective purchasers of a REMIC Residual Interest Security
should consult their tax advisors regarding the possible application of such
regulations. See "Certain Federal Income Tax Considerations -- Taxation of
Holders of Residual Interest Securities -- Mark to Market Rules."
 
     Unsecured Home Improvement and Other Loans.  The Trust Fund for any Series
may include Home Improvement Contracts that are not secured by an interest in
real estate or otherwise. The Trust Fund for any Series may also include home
equity contracts that were originated with Loan-to-Value Ratios or Combined
Loan-to-Value Ratios in excess of the value of the related Mortgaged Property
pledged as security therefor. Under such circumstances, the Trust Fund for the
related Series could be treated as a general unsecured creditor as to any
unsecured portion of any such Loan. In the event of a default under a Loan that
is unsecured in whole or in part, the related Trust Fund will have recourse only
against the borrower's assets generally for the unsecured portion of the Loan,
along with all other general unsecured creditors of the borrower. In a
bankruptcy or insolvency proceeding relating to a borrower on any such Loan, the
unsecured obligations of the borrower with respect to such Loan may be
discharged, even though the value of the borrower's assets made available to the
related Trust Fund as a general unsecured creditor is insufficient to pay
amounts due and owning under the related Loan.
 
     Risk of Losses Associated with Adjustable Rate Loans.  Adjustable rate
Loans may be underwritten on the basis of an assessment that Mortgagors will
have the ability to make payments in higher amounts after relatively short
periods of time. In some instances, Mortgagors' income may not be sufficient to
enable them to continue to make their loan payments as such payments increase
and thus the likelihood of default will increase.
 
     Potential Liability For Environmental Conditions.  Real property pledged as
security to a lender may be subject to certain environmental risks. Federal,
state and local laws and regulations impose a wide range of requirements on
activities that may affect the environment, health and safety. In certain
circumstances, these laws and regulations impose obligations on owners or
operators of residential properties such as those subject to the Loans. The
failure to comply with such laws and regulations may result in fines and
penalties.
 
     In particular, under various federal, state and local laws and regulations,
an owner or operator of real estate may be liable for the costs of addressing
hazardous substances on, in or beneath such property and related costs. Such
liability could exceed the value of the property and the aggregate assets of the
owner or operator. In addition, persons who transport or dispose of hazardous
substances, or arrange for the transportation, disposal or treatment of
hazardous substances, at off-site locations may also be held liable if there are
releases or threatened releases of hazardous substances at such off-site
locations.

     In addition, under the laws of some states and under the Federal
Comprehensive Environmental Response, Compensation and Liability Act ("CERCLA"),
contamination of property may give rise to a lien on the property to assure the
payment of the costs of clean-up. In several states, such a lien has priority
over the lien of an existing mortgage against such property.
 
     Under the laws of some states, and under CERCLA and the Federal Solid Waste
Disposal Act, there is a possibility that a lender may be held liable as an
"owner" or "operator" for costs of addressing releases or threatened releases of
hazardous substances at a property, or releases of petroleum from an underground
storage tank, under certain circumstances. See "Certain Legal Aspects of the
Loans -- Environmental Risks."
 
     Consumer Protection Laws May Affect Loans.  Applicable state laws generally
regulate interest rates and other charges and require certain disclosures. In
addition, other state laws, public policy and general principles of equity
relating to the protection of consumers, unfair and deceptive practices and debt
collection practices may apply to the origination, servicing and collection of
the Loans. Depending on the provisions of the applicable law and the specific
facts and circumstances involved, violations of these laws, policies and
principles may limit the ability of the Servicer to collect all or part of the
principal of or interest on the Loans, may entitle the borrower to a refund of
amounts previously paid and, in addition, could subject the owner of the Loan to
damages and administrative enforcement.
 
     The Loans are also subject to federal laws, including:
 
          (i) the Federal Truth in Lending Act and Regulation Z promulgated
     thereunder, which require certain disclosures to the borrowers regarding
     the terms of the Loans;
 
          (ii) the Equal Credit Opportunity Act and Regulation B promulgated
     thereunder, which prohibit discrimination on the basis of age, race, color,
     sex, religion, marital status, national origin, receipt of public
     assistance or the exercise of any right under the Consumer Credit
     Protection Act, in the extension of credit;
 
          (iii) the Fair Credit Reporting Act, which regulates the use and
     reporting of information related to the borrower's credit experience; and
 
          (iv) for loans that were originated or closed after November 7, 1989,
     the Home Equity Loan Consumer Protection Act of 1988, which requires
     additional application disclosures, limits changes that may be made to the
     loan documents without the borrower's consent and restricts a lender's
     ability to declare a default or to suspend or reduce a borrower's credit
     limit to certain enumerated events.
 
     The Riegle Act.  Certain mortgage loans are subject to the Riegle Community
Development and Regulatory Improvement Act of 1994 (the "Riegle Act"), which
incorporates the Home Ownership and Equity Protection Act of 1994. These
provisions impose additional disclosure and other requirements on creditors with
respect to non-purchase money mortgage loans with high interest rates or high
up-front fees and charges. The provisions of the Riegle Act apply on a mandatory
basis to all mortgage loans originated on or after October 1, 1995. These
provisions can impose specified statutory liabilities upon creditors who fail to
comply with their provisions and may affect the enforceability of the related
loans. In addition, any assignee of the creditor would generally be subject to
all claims and defenses that the consumer could assert against the creditor,
including, without limitation, the right to rescind the mortgage loan.
 
     The Home Improvement Contracts are also subject to the Preservation of
Consumers' Claims and Defenses regulations of the Federal Trade Commission and
other similar federal and state statutes and regulations (collectively, the
"Holder in Due Course Rules"), which protect the homeowner from defective
craftsmanship or incomplete work by a contractor. These laws permit the obligor
to withhold payment if the work does not meet the quality and durability
standards agreed to by the homeowner and the contractor. The Holder in Due
Course Rules have the effect of subjecting any assignee of the seller in a
consumer credit transaction to all claims and defenses the obligor in the credit
sale transaction could assert against the seller of the goods.
 
     Violations of certain provisions of these federal laws may limit the
ability of the Servicer to collect all or part of the principal of or interest
on the Loans and in addition, could subject the Trust Fund to damages and
administrative enforcement. See "Certain Legal Aspects of the Loans."
 
                                       19
<PAGE>   116
 
     Contracts Will Not Be Stamped.  In order to give notice of the right, title
and interest of Holders to the Home Improvement Contracts, the Depositor will
cause a UCC-1 financing statement to be executed by the Depositor or the Seller
identifying the applicable Trustee as the secured party and identifying all Home
Improvement Contracts as collateral. Unless otherwise specified in the related
Prospectus Supplement, the Home Improvement Contracts will not be stamped or
otherwise marked to reflect their assignment to the Trust Fund. Therefore, if,
through negligence, fraud or otherwise, a subsequent purchaser were able to take
physical possession of the Home Improvement Contracts without notice of such
assignment, the interest of Holders in the Home Improvement Contracts could be
defeated. See "Certain Legal Aspects of the Loans -- The Home Improvement
Contracts."
 
     Ratings Are Not Recommendations.  It will be a condition to the issuance of
a Series of Securities that they be rated in one of the four highest rating
categories by the Rating Agencies identified in the related Prospectus
Supplement. Any such rating would be based on, among other things, the adequacy
of the value of the Primary Assets and any Enhancement with respect to such
Series. Such rating should not be deemed a recommendation to purchase, hold or
sell Securities, inasmuch as it does not address market price or suitability for
a particular investor. There is also no assurance that any such rating will
remain in effect for any given period of time or may not be lowered or withdrawn
entirely by the Rating Agencies if in their judgment circumstances in the future
so warrant. In addition to being lowered or withdrawn due to any erosion in the
adequacy of the value of the Primary Assets, such rating might also be lowered
or withdrawn, among other reasons, because of an adverse change in the financial
or other condition of an Enhancer or a change in the rating of such Enhancer's
long term debt.
 
                         DESCRIPTION OF THE SECURITIES
 
GENERAL
 
     Each Series of Notes will be issued pursuant to an indenture (each, an
"Indenture") between the related Trust Fund and the entity named in the related
Prospectus Supplement as Indenture Trustee with respect to such Series. A form
of Indenture has been filed as an exhibit to the Registration Statement of which
this Prospectus forms a part. The Certificates will also be issued in Series
pursuant to separate agreements (each, a "Pooling and Servicing Agreement" or a
"Trust Agreement") among the Depositor, the Servicer, if the Series relates to
Loans, and the Trustee. A form of Pooling and Servicing Agreement has been filed
as an exhibit to the Registration Statement of which this Prospectus forms a
part. A Series may consist of both Notes and Certificates.
 
     The Seller may agree to reimburse the Depositor for certain fees and
expenses of the Depositor incurred in connection with the offering of the
Securities.
 
     The following summaries describe certain provisions in the Agreements
common to each Series of Securities. The summaries do not purport to be complete
and are subject to, and are qualified in their entirety by reference to, the
provisions of the Agreements and the Prospectus Supplement relating to each
Series of Securities. Where particular provisions or terms used in the
Agreements are referred to, the actual provisions (including definitions of
terms) are incorporated herein by reference as part of such summaries.
 
     Each Series of Securities will consist of one or more Classes of
Securities, one or more of which may be Compound Interest Securities, Variable
Interest Securities, PAC Securities, Zero Coupon Securities, Principal Only
Securities, Interest Only Securities or Participating Securities. A Series may
also include one or more Classes of Subordinated Securities. The Securities of
each Series will be issued only in fully registered form, without coupons, in
the authorized denominations for each Class specified in the related Prospectus
Supplement. Upon satisfaction of the conditions, if any, applicable to a Class
of a Series, as described in the related Prospectus Supplement, the transfer of
the Securities may be registered and the Securities may be exchanged at the
office of the applicable Trustee specified in the Prospectus Supplement without
the payment of any service charge other than any tax or governmental charge
payable in connection with such registration of transfer or exchange. If
specified in the related Prospectus Supplement, one or more Classes of a Series
may be available in book-entry form only.
 
                                       20
<PAGE>   117
 
     Unless otherwise provided in the related Prospectus Supplement, payments of
principal of and interest on a Series of Securities will be made on the
Distribution Dates specified in the Prospectus Supplement relating to such
Series by check mailed to Holders of such Series, registered as such at the
close of business on the record date specified in the related Prospectus
Supplement applicable to such Distribution Dates at their addresses appearing on
the security register, except that (a) payments may be made by wire transfer (at
the expense of the Holder requesting payment by wire transfer) in certain
circumstances described in the related Prospectus Supplement and (b) final
payments of principal in retirement of each Security will be made only upon
presentation and surrender of such Security at the office of the applicable
Trustee specified in the Prospectus Supplement. Notice of the final payment on a
Security will be mailed to the Holder of such Security before the Distribution
Date on which the final principal payment on any Security is expected to be made
to the Holder of such Security.
 
     Payments of principal of and interest on the Securities will be made by the
applicable Trustee, or a paying agent on behalf of such Trustee, as specified in
the related Prospectus Supplement. Unless otherwise provided in the related
Prospectus Supplement, all payments with respect to the Primary Assets for a
Series, together with reinvestment income thereon, amounts withdrawn from any
Reserve Fund, and amounts available pursuant to any other Enhancement will be
deposited directly into the Collection Account. If provided in the related
Prospectus Supplement, such deposits may be net of certain amounts payable to
the related Servicer and any other person specified in such Prospectus
Supplement. Such amounts thereafter will be deposited into the Distribution
Account(s) and will be available to make payments on the Securities of such
Series on the next Distribution Date. See "The Trust Funds -- Collection and
Distribution Accounts."
 
VALUATION OF THE PRIMARY ASSETS
 
     If specified in the related Prospectus Supplement for a Series of Notes,
each Primary Asset included in the related Trust Fund for a Series will be
assigned an initial "Asset Value." Unless otherwise specified in the related
Prospectus Supplement, at any time the Asset Value of the Primary Assets will be
equal to the product of the Asset Value Percentage as set forth in the Indenture
and the lesser of (a) the stream of remaining regularly scheduled payments on
the Primary Assets, net, unless otherwise provided in the related Prospectus
Supplement, of certain amounts payable as expenses, together with income earned
on each such scheduled payment received through the day preceding the next
Distribution Date at the Assumed Reinvestment Rate, if any, discounted to
present value at the highest interest rate on the Notes of such Series over
periods equal to the interval between payments on the Notes, and (b) the
then-outstanding Principal Balance of the Primary Assets. Unless otherwise
specified in the related Prospectus Supplement, the initial Asset Value of the
Primary Assets will be at least equal to the principal amount of the Notes of
the related Series at the date of issuance thereof.
 
     The "Assumed Reinvestment Rate," if any, for a Series will be the highest
rate permitted by the Rating Agencies or a rate insured by means of a surety
bond, guaranteed investment contract, Deposit Agreement or other arrangement
satisfactory to the Rating Agencies. If the Assumed Reinvestment Rate is so
insured, the related Prospectus Supplement will set forth the terms of such
arrangement.
 
PAYMENTS OF INTEREST
 
     The Securities of each Class by their terms entitled to receive interest
will bear interest (calculated, unless otherwise specified in the related
Prospectus Supplement, on the basis of a 360-day year of twelve 30-day months)
from the date and at the per annum rate specified, or calculated in the method
described, in the related Prospectus Supplement. Interest on such Securities of
a Series will be payable on the Distribution Date specified in the related
Prospectus Supplement. The rate of interest on Securities of a Series may be
variable or may change with changes in the annual percentage rates of the Loans
or Underlying Loans relating to the Private Securities, as applicable, included
in the related Trust Fund and/or as prepayments occur with respect to such Loans
or Underlying Loans, as applicable. Principal Only Securities may not be
entitled to receive any interest distributions or may be entitled to receive
only nominal interest distributions. Any interest on Zero Coupon Securities that
is not paid on the related Distribution Date will accrue and be added to the
principal thereof on such Distribution Date.
 
                                       21
<PAGE>   118
 
     Interest payable on the Securities on a Distribution Date will include all
interest accrued during the period specified in the related Prospectus
Supplement. In the event interest accrues during the calendar month preceding a
Distribution Date, the effective yield to Holders will be reduced from the yield
that would otherwise be obtainable if interest payable on the Securities were to
accrue through the day immediately preceding such Distribution Date.
 
PAYMENTS OF PRINCIPAL
 
     On each Distribution Date for a Series, principal payments will be made to
the Holders of the Securities of such Series on which principal is then payable,
to the extent set forth in the related Prospectus Supplement. Such payments will
be made in an aggregate amount determined as specified in the related Prospectus
Supplement and will be allocated among the respective Classes of a Series in the
manner, at the times and in the priority (which may, in certain cases, include
allocation by random lot) set forth in the related Prospectus Supplement.
 
FINAL SCHEDULED DISTRIBUTION DATE
 
     The Final Scheduled Distribution Date with respect to each Class of a
Series of Notes is the date no later than which the principal thereof will be
fully paid and with respect to each Class of a Series of Certificates will be
the date on which the entire aggregate principal balance of such Class is
expected to be reduced to zero, in each case calculated on the basis of the
assumptions applicable to such Series described in the related Prospectus
Supplement. The Final Scheduled Distribution Date for each Class of a Series
will be specified in the related Prospectus Supplement. Since payments on the
Primary Assets will be used to make distributions in reduction of the
outstanding principal amount of the Securities, it is likely that the actual
final Distribution Date of any such Class will occur earlier, and may occur
substantially earlier, than its Final Scheduled Distribution Date. Furthermore,
with respect to a Series of Certificates, unless otherwise specified in the
related Prospectus Supplement, as a result of delinquencies, defaults and
liquidations of the Primary Assets in the Trust Fund, the actual final
Distribution Date of any Certificate may occur later than its Final Scheduled
Distribution Date. No assurance can be given as to the actual prepayment
experience with respect to a Series. See "Weighted Average Life of the
Securities" below.
 
SPECIAL REDEMPTION
 
     If so specified in the Prospectus Supplement relating to a Series of
Securities having other than monthly Distribution Dates, one or more Classes of
Securities of such Series may be subject to special redemption, in whole or in
part, on the day specified in the related Prospectus Supplement (the "Special
Redemption Date") if, as a consequence of prepayments on the Loans or Underlying
Loans, as applicable, relating to such Securities, or low yields then available
for reinvestment, the entity specified in the related Prospectus Supplement
determines, based on assumptions specified in the applicable Agreement, that the
amount available for the payment of interest that will have accrued on such
Securities (the "Available Interest Amount") through the designated interest
accrual date specified in the related Prospectus Supplement is less than the
amount of interest that will have accrued on such Securities to such date. In
such event and as further described in the related Prospectus Supplement, the
applicable Trustee will redeem a principal amount of outstanding Securities of
such Series as will cause the Available Interest Amount to equal the amount of
interest that will have accrued through such designated interest accrual date
for such Series of Securities outstanding immediately after such redemption.
 
OPTIONAL REDEMPTION, PURCHASE OR TERMINATION
 
     The Depositor or the Servicer may, at its option, redeem, in whole or in
part, one or more Classes of Notes or purchase one or more Classes of
Certificates of any Series, on any Distribution Date under the circumstances, if
any, specified in the Prospectus Supplement relating to such Series.
Alternatively, if so specified in the related Prospectus Supplement for a Series
of Certificates, the Depositor, the Servicer, or another entity designated in
the related Prospectus Supplement may, at its option, cause an early termination
of a Trust Fund by repurchasing all of the Primary Assets from such Trust Fund
on or after a date specified in the related Prospectus Supplement, or on or
after such time as the aggregate outstanding principal amount of the
Certificates or Primary Assets, as specified in the related Prospectus
Supplement, is equal to or less than
                                       22
<PAGE>   119
 
the amount or percentage specified in the related Prospectus Supplement. Notice
of such redemption, purchase or termination must be given by the Depositor or
the Trustee prior to the related date. The redemption, purchase or repurchase
price will be set forth in the related Prospectus Supplement. If specified in
the related Prospectus Supplement, in the event that a REMIC election has been
made, the Trustee shall receive a satisfactory opinion of counsel that the
optional redemption, purchase or termination will be conducted so as to
constitute a "qualified liquidation" under Section 860F of the Code.
 
     In addition, the Prospectus Supplement may provide other circumstances
under which Holders of Securities of a Series could be fully paid significantly
earlier than would otherwise be the case if payments or distributions were
solely based on the activity of the related Primary Assets.
 
WEIGHTED AVERAGE LIFE OF THE SECURITIES
 
     Weighted average life refers to the average amount of time that will elapse
from the date of issue of a security until each dollar of principal of such
security will be repaid to the investor. Unless otherwise specified in the
related Prospectus Supplement, the weighted average life of the Securities of a
Class will be influenced by the rate at which the amount financed under the
Loans or Underlying Loans relating to the Private Securities, as applicable,
included in the Trust Fund for a Series is paid, which may be in the form of
scheduled amortization or prepayments.
 
     Prepayments on loans and other receivables can be measured relative to a
prepayment standard or model. The Prospectus Supplement for a Series of
Securities will describe the prepayment standard or model, if any, used and may
contain tables setting forth the projected weighted average life of each Class
of Securities of such Series and the percentage of the original principal amount
of each Class of Securities of such Series that would be outstanding on
specified Distribution Dates for such Series based on the assumptions stated in
such Prospectus Supplement, including assumptions that prepayments on the Loans
or Underlying Loans relating to the Private Securities, as applicable, included
in the related Trust Fund are made at rates corresponding to various percentages
of the prepayment standard or model specified in such Prospectus Supplement.
 
     There is, however, no assurance that prepayment of the Loans or Underlying
Loans relating to the Private Securities, as applicable, included in the related
Trust Fund will conform to any level of any prepayment standard or model
specified in the related Prospectus Supplement. The rate of principal
prepayments on pools of loans may be influenced by a variety of factors,
including job related factors such as transfers, layoffs or promotions and
personal factors such as divorce, disability or prolonged illness. Economic
conditions, either generally or within a particular geographic area or industry,
also may affect the rate of principal prepayments. Demographic and social
factors may influence the rate of principal prepayments in that some borrowers
have greater financial flexibility to move or refinance than do other borrowers.
The deductibility of mortgage interest payments, servicing decisions and other
factors also affect the rate of principal prepayments. As a result, there can be
no assurance as to the rate or timing of principal prepayments of the Loans or
Underlying Loans either from time to time or over the lives of such Loans or
Underlying Loans.
 
     The rate of prepayments of conventional housing loans and other receivables
has fluctuated significantly in recent years. In general, however, if prevailing
interest rates fall significantly below the interest rates on the Loans or
Underlying Loans relating to the Private Securities, as applicable, for a
Series, such loans are likely to prepay at rates higher than if prevailing
interest rates remain at or above the interest rates borne by such loans. In
this regard, it should be noted that the Loans or Underlying Loans, as
applicable, for a Series may have different interest rates. In addition, the
weighted average life of the Securities may be affected by the varying
maturities of the Loans or Underlying Loans relating to the Private Securities,
as applicable. If any Loans or Underlying Loans relating to the Private
Securities, as applicable, for a Series have actual terms-to-stated maturity of
less than those assumed in calculating the Final Scheduled Distribution Date of
the related Securities, one or more Classes of the Series may be fully paid
prior to their respective Final Scheduled Distribution Date, even in the absence
of prepayments and a reinvestment return higher than the Assumed Reinvestment
Rate.

<PAGE>   120
 
                                THE TRUST FUNDS
 
GENERAL
 
     The Notes of each Series will be secured by the pledge of the assets of the
related Trust Fund, and the Certificates of each Series will represent interests
in the assets of the related Trust Fund. The Trust Fund of each Series will
include assets purchased from the Seller composed of (i) the Primary Assets,
(ii) amounts available from the reinvestment of payments on such Primary Assets
at the Assumed Reinvestment Rate, if any, specified in the related Prospectus
Supplement, (iii) any Enhancement, (iv) any Property that secured a Loan but
which is acquired by foreclosure or deed in lieu of foreclosure or repossession
and (v) the amount, if any, initially deposited into the Collection Account or
Distribution Account(s) for a Series as specified in the related Prospectus
Supplement.
 
     The Securities will be non-recourse obligations of the related Trust Fund.
The assets of the Trust Fund specified in the related Prospectus Supplement for
a Series of Securities, unless otherwise specified in the related Prospectus
Supplement, will serve as collateral only for that Series of Securities. Holders
of a Series of Notes may only proceed against such collateral securing such
Series of Notes in the case of a default with respect to such Series of Notes
and may not proceed against any assets of the Depositor or the related Trust
Fund not pledged to secure such Notes.
 
     The Primary Assets for a Series will be sold by the Seller to the Depositor
or purchased by the Depositor in the open market or in privately negotiated
transactions, which may include transactions with affiliates and will be
transferred by the Depositor to the Trust Fund. Loans relating to a Series will
be serviced by the Servicer, which may be the Seller, specified in the related
Prospectus Supplement, pursuant to a Pooling and Servicing Agreement, with
respect to a Series of Certificates or a servicing agreement (each, a "Servicing
Agreement") between the Trust Fund and Servicer, with respect to a Series of
Notes.
 
     If so specified in the related Prospectus Supplement, a Trust Fund relating
to a Series of Securities may be a business trust formed under the laws of the
state specified in the related Prospectus Supplement pursuant to a trust
agreement (each, a "Trust Agreement") between the Depositor and the Trustee of
such Trust Fund specified in the related Prospectus Supplement.
 
     With respect to each Trust Fund, prior to the initial offering of the
related Series of Securities, the Trust Fund will have no assets or liabilities.
No Trust Fund is expected to engage in any activities other than acquiring,
managing and holding the related Primary Assets and other assets contemplated
herein and in the related Prospectus Supplement and the proceeds thereof,
issuing Securities and making payments and distributions thereon and certain
related activities. No Trust Fund is expected to have any source of capital
other than its assets and any related Enhancement.
 
     Primary Assets included in the Trust Fund for a Series may consist of any
combination of Loans and Private Securities, to the extent and as specified in
the related Prospectus Supplement.
 
THE LOANS
 
     Mortgage Loans.  The Primary Assets for a Series may consist, in whole or
in part, of closed-end home equity loans (the "Closed-End Loans") and/or
revolving home equity loans or certain balances therein (the "Revolving Credit
Line Loans" and, together with the Closed-End Loans, the "Mortgage Loans")
secured by mortgages primarily on Single Family Properties that may be
subordinated to other mortgages on the same Mortgaged Property. The Mortgage
Loans may have fixed interest rates or adjustable interest rates and may provide
for other payment characteristics as described below and in the related
Prospectus Supplement.
 
     The full principal amount of a Closed-End Loan is advanced at origination
of the loan and generally is repayable in equal (or substantially equal)
installments of an amount sufficient to fully amortize such loan at its stated
maturity. Unless otherwise described in the related Prospectus Supplement, the
original terms to stated maturity of Closed-End Loans will not exceed 360
months. Principal amounts on a Revolving Credit Line Loan may be drawn down (up
to a maximum amount as set forth in the related Prospectus Supplement) or repaid
under each Revolving Credit Line Loan from time to time, but may be subject to a
minimum periodic payment. Except to the extent provided in the related
Prospectus Supplement, the Trust Fund will not include any amounts borrowed
under a Revolving Credit Line Loan after the Cut-off Date. As more fully
                                       24
<PAGE>   121
 
described in the related Prospectus Supplement, interest on each Revolving
Credit Line Loan, excluding introductory rates offered from time to time during
promotional periods, is computed and payable monthly on the average daily
Principal Balance of such Loan. Under certain circumstances, under either a
Revolving Credit Line Loan or a Closed-End Loan, a borrower may choose an
interest only payment option and is obligated to pay only the amount of interest
that accrues on the loan during the billing cycle. An interest only payment
option may be available for a specified period before the borrower must begin
paying at least the minimum monthly payment of a specified percentage of the
average outstanding balance of the loan.
 
     The rate of prepayment on the Mortgage Loans cannot be predicted. Home
equity loans have been originated in significant volume only during the past few
years and the Depositor is not aware of any publicly available studies or
statistics on the rate of prepayment of such loans. Generally, home equity loans
are not viewed by borrowers as permanent financing. Accordingly, the Mortgage
Loans may experience a higher rate of prepayment than traditional first mortgage
loans. On the other hand, because home equity loans such as the Revolving Credit
Line Loans generally are not fully amortizing, the absence of voluntary borrower
prepayments could cause rates of principal payments lower than, or similar to,
those of traditional fully-amortizing first mortgages. The prepayment experience
of the related Trust Fund may be affected by a wide variety of factors,
including general economic conditions, prevailing interest rate levels, the
availability of alternative financing and homeowner mobility and the frequency
and amount of any future draws on any Revolving Credit Line Loans. Other factors
that might be expected to affect the prepayment rate of a pool of home equity
mortgage loans or home improvement contracts include the amounts of, and
interest rates on, the underlying first mortgage loans, and the use of first
mortgage loans as long-term financing for home purchase and subordinate mortgage
loans as shorter-term financing for a variety of purposes, including home
improvement, education expenses and purchases of consumer durables such as
automobiles. Accordingly, the Mortgage Loans may experience a higher rate of
prepayment than traditional fixed-rate mortgage loans. In addition, any future
limitations on the right of borrowers to deduct interest payments on home equity
loans for federal income tax purposes may further increase the rate of
prepayments of the Loans. Moreover, the enforcement of a "due-on-sale" provision
(as described below) will have the same effect as a prepayment of the related
Loan. See "Certain Legal Aspects of the Loans -- Due-on-Sale Clauses in Mortgage
Loans."
 
     Collections on Revolving Credit Line Loans may vary because, among other
things, borrowers may (i) make payments during any month as low as the minimum
monthly payment for such month or, during the interest-only period for certain
Revolving Credit Line Loans and, in more limited circumstances, Closed-End Loans
with respect to which an interest-only payment option has been selected, the
interest and the fees and charges for such month or (ii) make payments as high
as the entire Principal Balance plus accrued interest and the fees and charges
thereon. It is possible that borrowers may fail to make the required periodic
payments. In addition, collections on the Mortgage Loans may vary due to
seasonal purchasing and the payment habits of borrowers.
 
     The Mortgaged Properties will include Single Family Property (i.e., one- to
four-family residential housing, including Condominium Units and Cooperative
Dwellings) and mixed-use property. Mixed-use properties will consist of
structures of no more than three stories that include one- to four-residential
dwelling units and space used for retail, professional or other commercial uses.
Such uses, which will not involve more than 50% of the space in the structure,
may include doctor, dentist or law offices, real estate agencies, boutiques,
newsstands, convenience stores or other similar types of uses intended to cater
to individual customers as specified in the related Prospectus Supplement. The
properties may be located in suburban or metropolitan districts. Any such
non-residential use will be in compliance with local zoning laws and
regulations. The Mortgaged Properties may consist of detached individual
dwellings, individual condominiums, townhouses, duplexes, row houses, individual
units in planned unit developments and other attached dwelling units. Each
Single Family Property will be located on land owned in fee simple by the
borrower or on land leased by the borrower for a term at least ten years (unless
otherwise provided in the related Prospectus Supplement) greater than the term
of the related Loan. Attached dwellings may include owner-occupied structures
where each borrower owns the land upon which the unit is built, with the
remaining adjacent land owned in common or dwelling units subject to a
proprietary lease or occupancy agreement in a cooperatively owned apartment
building.
 
                                       25
<PAGE>   122
 
     Unless otherwise specified in the related Prospectus Supplement, Mortgages
on Cooperative Dwellings consist of a lien on the shares issued by such
Cooperative Dwelling and the proprietary lease or occupancy agreement relating
to such Cooperative Dwelling.
 
     The aggregate Principal Balance of Loans secured by Properties that are
owner-occupied will be disclosed in the related Prospectus Supplement. Unless
otherwise specified in the Prospectus Supplement, the sole basis for a
representation that a given percentage of the Loans are secured by Single Family
Property that is owner-occupied will be either (i) the making of a
representation by the Mortgagor at origination of the Mortgage Loan either that
the underlying Mortgaged Property will be used by the Mortgagor for a period of
at least six months every year or that the Mortgagor intends to use the
Mortgaged Property as a primary residence, or (ii) a finding that the address of
the underlying Mortgaged Property is the Mortgagor's mailing address as
reflected in the Servicer's records. To the extent specified in the related
Prospectus Supplement, the Mortgaged Properties may include non-owner occupied
investment properties and vacation and second homes.
 
     Unless otherwise specified in the related Prospectus Supplement, the
initial Combined Loan-to-Value Ratio of a Loan is computed in the manner
described in the related Prospectus Supplement, taking into account the amounts
of any related senior mortgage loans.
 
     Home Improvement Contracts.  The Primary Assets for a Series may consist,
in whole or in part, of home improvement installment sales contracts and
installment loan agreements (the "Home Improvement Contracts") originated by a
home improvement contractor in the ordinary course of business. As specified in
the related Prospectus Supplement, the Home Improvement Contracts will either be
unsecured or secured by the Mortgages primarily on Single Family Properties,
which are generally subordinated to other mortgages on the same Mortgaged
Property or by purchase money security interests in the Home Improvements
financed thereby. Unless otherwise specified in the applicable Prospectus
Supplement, the Home Improvement Contracts will be fully amortizing and may have
fixed interest rates or adjustable interest rates and may provide for other
payment characteristics as described below and in the related Prospectus
Supplement.
 
     Unless otherwise specified in the related Prospectus Supplement, the home
improvements (the "Home Improvements") securing the Home Improvement Contracts
include, but are not limited to, replacement windows, house siding, new roofs,
swimming pools, satellite dishes, kitchen and bathroom remodeling goods and
solar heating panels. The initial Loan-to-Value Ratio of a Home Improvement
Contract will be computed in the manner described in the related Prospectus
Supplement.
 
     Additional Information.  The selection criteria that will apply with
respect to the Loans, including, but not limited to, the Combined Loan-to-Value
Ratios or Loan-to-Value Ratios, as applicable, original terms to maturity and
delinquency information, will be specified in the related Prospectus Supplement.
 
     The Loans for a Series may include Loans that do not amortize their entire
Principal Balance by their stated maturity in accordance with their terms and
require a balloon payment of the remaining Principal Balance at maturity, as
specified in the related Prospectus Supplement. As further described in the
related Prospectus Supplement, the Loans for a Series may include Loans that do
not have a specified stated maturity.
 
     The Loans will be conventional contracts or contracts insured by the
Federal Housing Administration (the "FHA") or partially guaranteed by the
Veterans Administration (the "VA"). Loans designated in the related Prospectus
Supplement as insured by the FHA will be insured by the FHA as authorized under
the United States Housing Act of 1937, as amended. Such Loans will be insured
under various FHA programs. These programs generally limit the principal amount
and interest rates of the mortgage loans insured. Loans insured by the FHA
generally require a minimum down payment of approximately 5% of the original
principal amount of the loan. No FHA-insured Loans relating to a Series may have
an interest rate or original principal amount exceeding the applicable FHA
limits at the time or origination of such loan.
 
     The insurance premiums for Loans insured by the FHA are collected by
lenders approved by the Department of Housing and Urban Development ("HUD") and
are paid to the FHA. The regulations governing FHA single-family mortgage
insurance programs provide that insurance benefits are payable either upon
foreclosure (or other acquisition of possession) and conveyance of the mortgaged
premises to HUD or upon assignment of the defaulted Loan to HUD. With respect to
a defaulted FHA-insured Loan, the Servicer
 
                                       26
<PAGE>   123
 
is limited in its ability to initiate foreclosure proceedings. When it is
determined, either by the Servicer or HUD, that default was caused by
circumstances beyond the mortgagor's control, the Servicer is expected to make
an effort to avoid foreclosure by entering, if feasible, into one of a number of
available forms of forbearance plans with the mortgagor. Such plans may involve
the reduction or suspension of regular mortgage payments for a specified period,
with such payments to be made upon or before the maturity date of the mortgage,
or the recasting of payments due under the mortgage up to or beyond the maturity
date. In addition, when a default caused by such circumstances is accompanied by
certain other criteria, HUD may provide relief by making payments to the
Servicer in partial or full satisfaction of amounts due under the Loan (which
payments are to be repaid by the mortgagor to HUD) or by accepting assignment of
the loan from the Servicer. With certain exceptions, at least three full monthly
installments must be due and unpaid under the Loan and HUD must have rejected
any request for relief from the mortgagor before the Servicer may initiate
foreclosure proceedings.
 
     HUD has the option, in most cases, to pay insurance claims in cash or in
debentures issued by HUD. Currently, claims are being paid in cash, and claims
have not been paid in debentures since 1965. HUD debentures issued in
satisfaction of FHA insurance claims bear interest at the applicable HUD
debenture interest rate. The Servicer of each FHA-insured Loan will be obligated
to purchase any such debenture issued in satisfaction of such Loan upon default
for an amount equal to the principal amount of any such debenture.
 
     The amount of insurance benefits generally paid by the FHA is equal to the
entire unpaid principal amount of the defaulted Loan adjusted to reimburse the
Servicer for certain costs and expenses and to deduct certain amounts received
or retained by the Servicer after default. When entitlement to insurance
benefits results from foreclosure (or other acquisition of possession) and
conveyance to HUD, the Servicer is compensated for no more than two-thirds of
its foreclosure costs, and is compensated for interest accrued and unpaid prior
to such date but in general only to the extent it was allowed pursuant to a
forbearance plan approved by HUD. When entitlement to insurance benefits results
from assignment of the Loan to HUD, the insurance payment includes full
compensation for interest accrued and unpaid to the assignment date. The
insurance payment itself, upon foreclosure of an FHA-insured Loan, bears
interest from a date 30 days after the mortgagor's first uncorrected failure to
perform any obligation to make any payment due under the Loan and, upon
assignment, from the date of assignment to the date of payment of the claim, in
each case at the same interest rate as the applicable HUD debenture interest
rate as described above.
 
     Loans designated in the related Prospectus Supplement as guaranteed by the
VA will be partially guaranteed by the VA under the Serviceman's Readjustment
Act of 1944, as amended (the "VA Guaranty"). The Serviceman's Readjustment Act
of 1944, as amended, permits a veteran (or in certain instances, the spouse of a
veteran) to obtain a mortgage loan guaranty by the VA covering mortgage
financing of the purchase of a one- to four-family dwelling unit at interest
rates permitted by the VA. The program has no mortgage loan limits, requires no
down payment from the purchaser and permits the guarantee of mortgage loans of
up to 30 years' duration.
 
     The maximum guaranty that may be issued by the VA under a VA guaranteed
mortgage loan depends upon the original principal amount of the mortgage loan,
as further described in 38 United States Code Section 1803(a), as amended. The
liability on the guaranty is reduced or increased pro rata with any reduction or
increase in the amount of indebtedness, but in no event will the amount payable
on the guaranty exceed the amount of the original guaranty. The VA may, at its
option and without regard to the guaranty, make full payment to a mortgage
holder of unsatisfied indebtedness on a mortgage upon its assignment to the VA.
 
     With respect to a defaulted VA guaranteed Loan, the Servicer is, absent
exceptional circumstances, authorized to announce its intention to foreclose
only when the default has continued for three months. Generally, a claim for the
guaranty is submitted after liquidation of the Mortgaged Property.
 
     The amount payable under the guaranty will be the percentage of the
VA-insured Loan originally guaranteed applied to indebtedness outstanding as of
the applicable date of computation specified in the VA regulations. Payments
under the guaranty will be equal to the unpaid principal amount of the loan,
interest accrued on the unpaid balance of the loan to the appropriate date of
computation and limited expenses of the mortgagee, but in each case only to the
extent that such amounts have not been recovered through liquidation
 
                                       27
<PAGE>   124
 
of the Mortgaged Property. The amount payable under the guaranty may in no event
exceed the amount of the original guaranty.
 
     The related Prospectus Supplement for each Series will provide information
with respect to the Loans that are Primary Assets as of the Cut-off Date,
including, among other things, and to the extent relevant: (a) the aggregate
unpaid Principal Balance of the Loans; (b) the range and weighted average Loan
Rate on the Loans, and, in the case of adjustable rate Loans, the range and
weighted average of the current Loan Rates and the Lifetime Rate Caps, if any;
(c) the range and average Principal Balance of the Loans; (d) the weighted
average original and remaining term-to-stated maturity of the Loans and the
range of original and remaining terms-to-stated maturity, if applicable; (e) the
range and weighted average of Combined Loan-to-Value Ratios or Loan-to-Value
Ratios for the Loans, as applicable; (f) the percentage (by Principal Balance as
of the Cut-off Date) of Loans that accrue interest at adjustable or fixed
interest rates; (g) any special hazard Insurance Policy or bankruptcy bond or
other enhancement relating to the Loans; (h) the percentage (by Principal
Balance as of the Cut-off Date) of Loans that are secured by Mortgaged
Properties or Home Improvements or that are unsecured; (i) the geographic
distribution of any Mortgaged Properties securing the Loans; (j) the percentage
of Loans (by Principal Balance as of the Cut-off Date) that are secured by
Single Family Properties, shares relating to Cooperative Dwellings, Condominium
Units, investment property and vacation or second homes; (k) the lien priority
of the Loans; (l) the delinquency status and year of origination of the Loans;
(m) whether such Loans are Closed-End Loans and/or Revolving Credit Line Loans;
and (n) in the case of Revolving Credit Line Loans, the general payments and
credit line terms of such Loans and other pertinent features thereof. The
related Prospectus Supplement will also specify any other limitations on the
types or characteristics of Loans for a Series.
 
     If information of the nature described above respecting the Loans is not
known to the Depositor at the time the Securities are initially offered,
approximate or more general information of the nature described above will be
provided in the Prospectus Supplement and additional information will be set
forth in a Current Report on Form 8-K to be available to investors on the date
of issuance of the related Series and to be filed with the Commission within 15
days after the initial issuance of such Securities.
 
PRIVATE SECURITIES
 
     General.  Primary Assets for a Series may consist, in whole or in part, of
Private Securities that include pass-through certificates representing
beneficial interests in loans of the type that would otherwise be eligible to be
Loans (the "Underlying Loans") or (b) collateralized obligations secured by
Underlying Loans. Such pass-through certificates or collateralized obligations
will have previously been (a) offered and distributed to the public pursuant to
an effective registration statement or (b) purchased in a transaction not
involving any public offering from a person who is not an affiliate of the
issuer of such securities at the time of sale (nor an affiliate thereof at any
time during the three preceding months); provided a period of three years
elapsed since the later of the date the securities were acquired from the issuer
or an affiliate thereof. Although individual Underlying Loans may be insured or
guaranteed by the United States or an agency or instrumentality thereof, they
need not be, and Private Securities themselves will not be so insured or
guaranteed.
 
     Private Securities will have been issued pursuant to a pooling and
servicing agreement, a trust agreement or similar agreement (a "PS Agreement").
The seller/servicer of the Underlying Loans will have entered into the PS
Agreement with the trustee under such PS Agreement (the "PS Trustee"). The PS
Trustee or its agent, or a custodian, will possess the Underlying Loans.
Underlying Loans will be serviced by a servicer (the "PS Servicer") directly or
by one or more sub-servicers who may be subject to the supervision of the PS
Servicer.
 
     The sponsor of the Private Securities (the "PS Sponsor") will be a
financial institution or other entity engaged generally in the business of
lending; a public agency or instrumentality of a state, local or federal
government; or a limited purpose corporation organized for the purpose of, among
other things, establishing trusts and acquiring and selling loans to such
trusts, and selling beneficial interests in such trusts. If so specified in the
Prospectus Supplement, the PS Sponsor may be an affiliate of the Depositor. The
obligations of the PS Sponsor will generally be limited to certain
representations and warranties with respect to the assets conveyed by it to the
related trust. Unless otherwise specified in the related Prospectus Supplement,
the PS
 
                                       28
<PAGE>   125
 
Sponsor will not have guaranteed any of the assets conveyed to the related trust
or any of the Private Securities issued under the PS Agreement. Additionally,
although the Underlying Loans may be guaranteed by an agency or instrumentality
of the United States, the Private Securities themselves will not be so
guaranteed.
 
     Distributions of principal and interest will be made on the Private
Securities on the dates specified in the related Prospectus Supplement. The
Private Securities may be entitled to receive nominal or no principal
distributions or nominal or no interest distributions. Principal and interest
distributions will be made on the Private Securities by the PS Trustee or the PS
Servicer. The PS Sponsor or the PS Servicer may have the right to repurchase the
Underlying Loans after a certain date or under other circumstances specified in
the related Prospectus Supplement.
 
     The Underlying Loans may be fixed rate, level payment, fully amortizing
loans or adjustable rate loans or loans having balloon or other irregular
payment features. Such Underlying Loans will be secured by mortgages on
Mortgaged Properties.
 
     Credit Support Relating to Private Securities.  Credit support in the form
of Reserve Funds, subordination of other private securities issued under the PS
Agreement, guarantees, cash collateral accounts, Security Policies or other
types of credit support may be provided with respect to the Underlying Loans or
with respect to the Private Securities themselves. The type, characteristics and
amount of credit support will be a function of certain characteristics of the
Underlying Loans and other factors and will have been established for the
Private Securities on the basis of requirements of the nationally recognized
statistical rating organization that rated the Private Securities.
 
     Additional Information.  The Prospectus Supplement for a Series for which
the Primary Assets include Private Securities will specify (such disclosure may
be on an approximate basis and will be as of the date specified in the related
Prospectus Supplement), to the extent relevant and to the extent such
information is reasonably available to the Depositor and the Depositor
reasonably believes such information to be reliable: (i) the aggregate
approximate principal amount and type of the Private Securities to be included
in the Trust Fund for such Series; (ii) certain characteristics of the
Underlying Loans, including (a) the payment features of such Underlying Loans
(i.e., whether they are Closed-End Loans and/or Revolving Credit Line Loans,
whether they are fixed rate or adjustable rate and whether they provide for
fixed level payments or other payment features), (b) the approximate aggregate
Principal Balance, if known, of such Underlying Loans insured or guaranteed by a
governmental entity, (c) the servicing fee or range of servicing fees with
respect to the Underlying Loans, (d) the minimum and maximum stated maturities
of such Underlying Loans at origination, (e) the lien priority of such
Underlying Loans and (f) the delinquency status and year of origination of such
Underlying Loans; (iii) the maximum original term-to-stated maturity of the
Private Securities; (iv) the weighted average term-to-stated maturity of the
Private Securities; (v) the pass-through or certificate rate or ranges thereof
for the Private Securities; (vi) the PS Sponsor, the PS Servicer (if other than
the PS Sponsor) and the PS Trustee for such Private Securities; (vii) certain
characteristics of credit support if any, such as Reserve Funds, Security
Policies or guarantees relating to such Loans underlying the Private Securities
or to such Private Securities themselves; (viii) the terms on which Underlying
Loans may, or are required to, be purchased prior to their stated maturity or
the stated maturity of the Private Securities; and (ix) the terms on which
Underlying Loans may be substituted for those originally underlying the Private
Securities.
 
     If information of the nature described above representing the Private
Securities is not known to the Depositor at the time the Securities are
initially offered, approximate or more general information of the nature
described above will be provided in the Prospectus Supplement and the additional
information, if available, will be set forth in a Current Report on Form 8-K to
be available to investors on the date of issuance of the related Series and to
be filed with the Commission within 15 days of the initial issuance of such
Securities.
 
COLLECTION AND DISTRIBUTION ACCOUNTS
 
     A separate Collection Account will be established by the Trustee or the
Servicer, in the name of the Trustee, for each Series of Securities for receipt
of the amount of cash, if any, specified in the related
 
                                       29
<PAGE>   126
 
Prospectus Supplement to be initially deposited therein by the Depositor, all
amounts received on or with respect to the Primary Assets and, unless otherwise
specified in the related Prospectus Supplement, income earned thereon. Certain
amounts on deposit in such Collection Account and certain amounts available
pursuant to any Enhancement, as provided in the related Prospectus Supplement,
will be deposited into the applicable Distribution Account, which will also be
established by the applicable Trustee for each such Series of Securities, for
distribution to the related Holders. Unless otherwise specified in the related
Prospectus Supplement, the applicable Trustee will invest the funds in the
Collection Account and the Distribution Account(s) in Eligible Investments
maturing, with certain exceptions, not later, in the case of funds in the
Collection Account, than the day preceding the date such funds are due to be
deposited into the Distribution Account(s) or otherwise distributed and, in the
case of funds in the Distribution Account(s), than the day preceding the next
Distribution Date for the related Series of Securities. Eligible Investments
include, among other investments, obligations of the United States and certain
agencies thereof, federal funds, certificates of deposit, commercial paper,
demand and time deposits and banker's acceptances, certain repurchase agreements
of United States government securities and certain guaranteed investment
contracts, in each case acceptable to the Rating Agencies.
 
     Notwithstanding any of the foregoing, amounts may be deposited and
withdrawn pursuant to any Deposit Agreement or Minimum Principal Payment
Agreement as specified in the related Prospectus Supplement.
 
     If specified in the related Prospectus Supplement, a Trust Fund will
include one or more segregated trust accounts (each, a "Pre-Funding Account")
established and maintained with the Trustee for the related Series. If so
specified, on the Closing Date for such Series, a portion of the proceeds of the
sale of the Securities of such Series (such amount, the "Pre-Funded Amount")
will be deposited into the Pre-Funding Account and may be used to purchase
additional Primary Assets during the period of time specified in the related
Prospectus Supplement (the "Pre-Funding Period"). In no case will the Pre-Funded
Amount exceed 50% of the aggregate principal amount of the related Securities,
and in no case will the Pre-Funding Period exceed one year. The Primary Assets
to be so purchased generally will be selected on the basis of the same criteria
as those used to select the initial Primary Assets, and the same representations
and warranties will be made with respect thereto. If any Pre-Funded Amount
remains on deposit in the Pre-Funding Account at the end of the Pre-Funding
Period, such amount will be applied in the manner specified in the related
Prospectus Supplement to prepay the Notes and/or the Certificates of the
applicable Series.
 
     If a Pre-Funding Account is established, one or more segregated trust
accounts (each, a "Capitalized Interest Account") may be established and
maintained with the Trustee for the related Series. On the Closing Date for such
Series, a portion of the proceeds of the sale of the Securities of such Series
will be deposited into the Capitalized Interest Account and used to fund the
excess, if any, of the sum of (i) the amount of interest accrued on the
Securities of such Series and (ii) if specified in the related Prospectus
Supplement, certain fees or expenses during the Pre-Funding Period, over the
amount of interest available therefor from the Primary Assets in the Trust Fund.
Any amounts on deposit in the Capitalized Interest Account at the end of the
Pre-Funding Period that are not necessary for such purposes will be distributed
to the person specified in the related Prospectus Supplement.
 
                                  ENHANCEMENT
 
     If stated in the Prospectus Supplement relating to a Series of Securities,
simultaneously with the Depositor's assignment of the Primary Assets to the
Trustee, the Depositor will obtain a Security Policy, issue Subordinated
Securities or obtain any other form of enhancement or combination thereof
(collectively, "Enhancement") in favor of the Trustee on behalf of the Holders
of the related Series or designated Classes of such Series from an institution
or by other means acceptable to the Rating Agencies. The Enhancement will
support the payment of principal of and interest on the Securities, and may be
applied for certain other purposes to the extent and under the conditions set
forth in such Prospectus Supplement. Enhancement for a Series may include one or
more of the following forms, or such other form as may be specified in the
related Prospectus Supplement. If so specified in the related Prospectus
Supplement, any of such Enhancement may be structured so as to protect against
losses relating to more than one Trust Fund, in the manner described therein.
 
                                       30
<PAGE>   127
 
SUBORDINATED SECURITIES
 
     If specified in the related Prospectus Supplement, Enhancement for a Series
may consist of one or more Classes of Subordinated Securities. The rights of the
related Subordinated Securityholders to receive distributions on any
Distribution Date will be subordinate in right and priority to the rights of
Holders of Senior Securities of the Series, but only to the extent described in
the related Prospectus Supplement.
 
INSURANCE
 
     If stated in the related Prospectus Supplement, Enhancement for a Series
may consist of special hazard Insurance Policies, bankruptcy bonds and other
types of insurance relating to the Primary Assets, as described below and in the
related Prospectus Supplement.
 
     Pool Insurance Policy.  If so specified in the Prospectus Supplement
relating to a Series of Securities, the Depositor will obtain a pool insurance
policy (the "Pool Insurance Policy") for the Loans in the related Trust Fund.
The Pool Insurance Policy will cover any loss (subject to the limitations
described in a related Prospectus Supplement) by reason of default. but will not
cover the portion of the Principal Balance of any Loan that is required to be
covered by any primary mortgage Insurance Policy. The amount and terms of any
such coverage will be set forth in the related Prospectus Supplement.
 
     Special Hazard Insurance Policy.  Although the terms of such policies vary
to some degree, a special hazard Insurance Policy typically provides that, where
there has been damage to Property securing a defaulted or foreclosed Loan (title
to which has been acquired by the insured) and to the extent such damage is not
covered by the standard hazard Insurance Policy or any flood Insurance Policy,
if applicable, required to be maintained with respect to such Property, or in
connection with partial loss resulting from the application of the coinsurance
clause in a standard hazard Insurance Policy, the special hazard insurer will
pay the lesser of (i) the cost of repair or replacement of such Property or (ii)
upon transfer of such Property to the special hazard insurer, the unpaid
Principal Balance of such Loan at the time of acquisition of such Property by
foreclosure or deed in lieu of foreclosure, plus accrued interest to the date of
claim settlement and certain expenses incurred by the Servicer with respect to
such Property. If the unpaid Principal Balance plus accrued interest and certain
expenses is paid by the special hazard insurer, the amount of further coverage
under the special hazard Insurance Policy will be reduced by such amount less
any net proceeds from the sale of such Property. Any amount paid as the cost of
repair of such Property will reduce coverage by such amount. Special hazard
Insurance Policies typically do not cover losses occasioned by war, civil
insurrection, certain governmental actions, errors in design, faulty workmanship
or materials (except under certain circumstances), nuclear reaction, flood (if
the mortgaged property is in a federally designated flood area), chemical
contamination and certain other risks.
 
     Restoration of the Property with the proceeds described under (i) above is
expected to satisfy the condition under any Pool Insurance Policy that such
Property be restored before a claim under such Pool Insurance Policy may be
validly presented with respect to the defaulted Loan secured by such Property.
The payment described under (ii) above will render unnecessary presentation of a
claim in respect of such Loan under any Pool Insurance Policy. Therefore, so
long as such Pool Insurance Policy remains in effect, the payment by the special
hazard insurer of the cost of repair or of the unpaid Principal Balance of the
related Loan plus accrued interest and certain expenses will not affect the
total amount in respect of insurance proceeds paid to Holders of the Securities,
but will affect the relative amounts of coverage remaining under the special
hazard Insurance Policy and Pool Insurance Policy.
 
     Bankruptcy Bond.  In the event of a bankruptcy of a borrower, the
bankruptcy court may establish the value of the Property securing the related
Loan at an amount less than the then-outstanding Principal Balance of such Loan.
The amount of the secured debt could be reduced to such value, and the holder of
such Loan thus would become an unsecured creditor to the extent the Principal
Balance of such Loan exceeds the value so assigned to the Property by the
bankruptcy court. In addition, certain other modifications of the terms of a
Loan can result from a bankruptcy proceeding. See "Certain Legal Aspects of the
Loans." If so provided in the related Prospectus Supplement, the Depositor or
other entity specified in the related Prospectus Supplement will obtain a
bankruptcy bond or similar insurance contract (the "bankruptcy bond") covering
losses resulting from proceedings with respect to borrowers under the Bankruptcy
Code. The bankruptcy bond
 
                                       31
<PAGE>   128
 
will cover certain losses resulting from a reduction by a bankruptcy court of
scheduled payments of principal of and interest on a Loan or a reduction by such
court of the principal amount of a Loan and will cover certain unpaid interest
on the amount of such a principal reduction from the date of the filing of a
bankruptcy petition.
 
     The bankruptcy bond will provide coverage in the aggregate amount specified
in the related Prospectus Supplement for all Loans in the Trust Fund for such
Series. Such amount will be reduced by payments made under such bankruptcy bond
in respect of such Loans, unless otherwise specified in the related Prospectus
Supplement, and will not be restored.
 
RESERVE FUNDS
 
     If so specified in the Prospectus Supplement relating to a Series of
Securities, the Depositor will deposit into one or more funds to be established
with the applicable Trustee as part of the Trust Fund for such Series or for the
benefit of any Enhancer with respect to such Series (each, a "Reserve Fund")
cash, a letter or letters of credit, cash collateral accounts, Eligible
Investments, or other instruments meeting the criteria of the Rating Agencies
rating any Series of the Securities in the amount specified in such Prospectus
Supplement. In the alternative or in addition to such deposit, a Reserve Fund
for a Series may be funded over time through application of all or a portion of
the excess cash flow from the Primary Assets for such Series, to the extent
described in the related Prospectus Supplement. If applicable, the initial
amount of the Reserve Fund and the Reserve Fund maintenance requirements for a
Series of Securities will be described in the related Prospectus Supplement.
 
     Amounts withdrawn from any Reserve Fund will be applied by the applicable
Trustee to make payments on the Securities of a Series, to pay expenses, to
reimburse any Enhancer or for any other purpose, in the manner and to the extent
specified in the related Prospectus Supplement.
 
     Amounts deposited into a Reserve Fund will be invested by the applicable
Trustee in Eligible Investments maturing no later than the day specified in the
related Prospectus Supplement.
 
MINIMUM PRINCIPAL PAYMENT AGREEMENT
 
     If stated in the Prospectus Supplement relating to a Series of Securities,
the Depositor will enter into a Minimum Principal Payment Agreement with an
entity meeting the criteria of the Rating Agencies pursuant to which such entity
will provide certain payments on the Securities of such Series in the event that
aggregate scheduled principal payments and/or prepayments on the Primary Assets
for such Series are not sufficient to make certain payments on the Securities of
such Series, as provided in the Prospectus Supplement.
 
DEPOSIT AGREEMENT
 
     If specified in a Prospectus Supplement, the Depositor and the applicable
Trustee for such Series of Securities will enter into a Deposit Agreement with
the entity specified in such Prospectus Supplement on or before the sale of such
Series of Securities. The purpose of a Deposit Agreement would be to accumulate
available cash for investment so that such cash, together with income thereon,
can be applied to future distributions on one or more Classes of Securities. The
Prospectus Supplement for a Series of Securities pursuant to which a Deposit
Agreement is used will contain a description of the terms of such Deposit
Agreement.
 
                               SERVICING OF LOANS
 
GENERAL
 
     Customary servicing functions with respect to Loans comprising the Primary
Assets in the Trust Fund will be provided by the Servicer directly pursuant to
the related Servicing Agreement or Pooling and Servicing Agreement, as the case
may be, with respect to a Series of Securities.
 
COLLECTION PROCEDURES; ESCROW ACCOUNTS
 
     The Servicer will make reasonable efforts to collect all payments required
to be made under the Loans and will, consistent with the terms of the related
Agreement for a Series and any applicable Enhancement, follow such collection
procedures as it follows with respect to comparable loans held in its own
portfolio.
                                       32
<PAGE>   129
 
Consistent with the above, the Servicer may, in its discretion, (i) waive any
assumption fee, late payment charge, or other charge in connection with a Loan
and (ii) to the extent provided in the related Agreement, arrange with an
obligor a schedule for the liquidation of delinquencies by extending the Due
Dates for Scheduled Payments on such Loan.
 
     If specified in the related Prospectus Supplement, the Servicer, to the
extent permitted by law, will establish and maintain escrow or impound accounts
(each, an "Escrow Account") with respect to Loans in which payments by obligors
to pay taxes, assessments, mortgage and hazard Insurance Policy premiums, and
other comparable items will be deposited. Loans may not require such payments
under the loan related documents, in which case the Servicer would not be
required to establish any Escrow Account with respect to such Loans. Withdrawals
from the Escrow Accounts are to be made to effect timely payment of taxes,
assessments and mortgage and hazard insurance, to refund to obligors amounts
determined to be overages, to pay interest to obligors on balances in the Escrow
Account to the extent required by law, to repair or otherwise protect the
property securing the related Loan and to clear and terminate such Escrow
Account. The Servicer will be responsible for the administration of the Escrow
Accounts and generally will make advances to such accounts when a deficiency
exists therein.
 
DEPOSITS TO AND WITHDRAWALS FROM THE COLLECTION ACCOUNT
 
     Unless otherwise specified in the related Prospectus Supplement, the
Trustee or the Servicer will establish a separate account (the "Collection
Account") in the name of the Trustee. Unless otherwise indicated in the related
Prospectus Supplement, the Collection Account will be an account maintained (i)
at a depository institution, the long-term unsecured debt obligations of which
at the time of any deposit therein are rated by each Rating Agency rating the
Securities of such Series at levels satisfactory to each Rating Agency or (ii)
in an account or accounts the deposits in which are insured to the maximum
extent available by the Federal Deposit Insurance Corporation or that are
secured in a manner meeting requirements established by each Rating Agency.
 
     Unless otherwise specified in the related Prospectus Supplement, the funds
held in the Collection Account may be invested in Eligible Investments. If so
specified in the related Prospectus Supplement, the Servicer will be entitled to
receive as additional compensation any interest or other income earned on funds
in the Collection Account.
 
     Unless otherwise specified in the related Prospectus Supplement, the
Servicer, the Depositor, the Trustee or the Seller, as appropriate, will deposit
into the Collection Account for each Series on the Business Day following the
Closing Date, any amounts representing Scheduled Payments due after the related
Cut-off Date but received by the Servicer on or before the Closing Date, and
thereafter, within two business days after the date of receipt thereof, the
following payments and collections received or made by it (other than, unless
otherwise provided in the related Prospectus Supplement, in respect of principal
of and interest on the related Primary Assets due on or before such Cut-off
Date):
 
          (i) All payments in respect of principal, including prepayments, on
     such Primary Assets;
 
          (ii) All payments in respect of interest on such Primary Assets after
     deducting therefrom, at the discretion of the Servicer but only to the
     extent of the amount permitted to be withdrawn or withheld from the
     Collection Account in accordance with the related Agreement, the Servicing
     Fee in respect of such Primary Assets;
 
          (iii) All amounts received by the Servicer in connection with the
     liquidation of Primary Assets or property acquired in respect thereof,
     whether through foreclosure sale, repossession or otherwise, including
     payments in connection with such Primary Assets received from the obligor,
     other than amounts required to be paid or refunded to the obligor pursuant
     to the terms of the applicable loan documents or otherwise pursuant to law,
     net of related liquidation expenses ("Liquidation Proceeds"), exclusive of,
     in the discretion of the Servicer, but only to the extent of the amount
     permitted to be withdrawn from the Collection Account in accordance with
     the related Agreement, the Servicing Fee, if any, in respect of the related
     Primary Asset;
 
                                       33
<PAGE>   130
 
          (iv) All proceeds under any title insurance, hazard Insurance Policy
     or other Insurance Policy covering any such Primary Asset, other than
     proceeds to be applied to the restoration or repair of the related Property
     or released to the obligor in accordance with the related Agreement;
 
          (v) All amounts required to be deposited therein from any Reserve Fund
     for such Series pursuant to the related Agreement;
 
          (vi) All Advances made by the Servicer required pursuant to the
     related Agreement; and
 
          (vii) All repurchase prices of any such Primary Assets repurchased by
     the Depositor, the Servicer or the Seller pursuant to the related
     Agreement.
 
     Unless otherwise specified in the related Prospectus Supplement, the
Servicer is permitted, from time to time, to make withdrawals from the
Collection Account for each Series for the following purposes:
 
          (i) to reimburse itself for Advances for such Series made by it
     pursuant to the related Agreement; provided, that the Servicer's right to
     reimburse itself is limited to amounts received on or in respect of
     particular Loans (including, for this purpose, Liquidation Proceeds and
     Insurance Proceeds) that represent late recoveries of Scheduled Payments
     with respect to which any such Advance was made;
 
          (ii) to the extent provided in the related Agreement, to reimburse
     itself for any Advances for such Series that the Servicer determines in
     good faith it will be unable to recover from amounts representing late
     recoveries of Scheduled Payments respecting which such Advance was made or
     from Liquidation Proceeds or Insurance Proceeds;
 
          (iii) to reimburse itself from Liquidation Proceeds for liquidation
     expenses and for amounts expended by it in good faith in connection with
     the restoration of damaged Property and, in the event deposited into the
     Collection Account and not previously withheld, and to the extent that
     Liquidation Proceeds after such reimbursement exceed the Principal Balance
     of the related Loan, together with accrued and unpaid interest thereon to
     the Due Date for such Loan next succeeding the date of its receipt of such
     Liquidation Proceeds, to pay to itself out of such excess the amount of any
     unpaid Servicing Fee and any assumption fees, late payment charges, or
     other charges on the related Loan;
 
          (iv) in the event it has elected not to pay itself the Servicing Fee
     out of the interest component of any Scheduled Payment, late payment or
     other recovery with respect to a particular Loan prior to the deposit of
     such Scheduled Payment, late payment or recovery into the Collection
     Account, to pay to itself the Servicing Fee, as adjusted pursuant to the
     related Agreement, from any such Scheduled Payment, late payment or such
     other recovery, to the extent permitted by the related Agreement;
 
          (v) to reimburse itself for expenses incurred by and recoverable by or
     reimbursable to it pursuant to the related Agreement;
 
          (vi) to pay to the applicable person with respect to each Primary
     Asset or REO Property acquired in respect thereof that has been repurchased
     or removed from the Trust Fund by the Depositor, the Servicer or the Seller
     pursuant to the related Agreement, all amounts received thereon and not
     distributed as of the date on which the related repurchase price was
     determined;
 
          (vii) to make payments to the applicable Trustee of such Series for
     deposit into the related Distribution Account, if any, or for remittance to
     the Holders of such Series in the amounts and in the manner provided for in
     the related Agreement; and
 
          (viii) to clear and terminate the Collection Account pursuant to the
     related Agreement.
 
     In addition, if the Servicer deposits into the Collection Account for a
Series any amount not required to be deposited therein, it may, at any time,
withdraw such amount from such Collection Account.
 
ADVANCES AND LIMITATIONS THEREON
 
     The related Prospectus Supplement will describe the circumstances, if any,
under which the Servicer will make Advances with respect to delinquent payments
on Loans. If specified in the related Prospectus Supplement, the Servicer will
be obligated to make Advances, and such obligation may be limited in amount, or
may not be activated until a certain portion of a specified Reserve Fund is
depleted. Advances are intended
 
                                       34
<PAGE>   131
 
to provide liquidity and, except to the extent specified in the related
Prospectus Supplement, not to guarantee or insure against losses. Accordingly,
any funds advanced are recoverable by the Servicer out of amounts received on
particular Loans that represent late recoveries of principal or interest,
Insurance Proceeds or Liquidation Proceeds respecting which any such Advance was
made. If an Advance is made and subsequently determined to be nonrecoverable
from late collections, Insurance Proceeds or Liquidation Proceeds from the
related Loan, the Servicer may be entitled to reimbursement from other funds in
the Collection Account or Distribution Account(s), as the case may be, or from a
specified Reserve Fund, as applicable, to the extent specified in the related
Prospectus Supplement.
 
MAINTENANCE OF INSURANCE POLICIES AND OTHER SERVICING PROCEDURES
 
     Standard Hazard Insurance; Flood Insurance.  Except as otherwise specified
in the related Prospectus Supplement, the Servicer will be required to maintain
or to cause the obligor on each Loan to maintain a standard hazard Insurance
Policy providing coverage of the standard form of fire insurance with extended
coverage for certain other hazards as is customary in the state in which the
related Property is located. The standard hazard Insurance Policies will provide
for coverage at least equal to the applicable state standard form of fire
Insurance Policy with extended coverage for property of the type securing the
related Loans. In general, the standard form of fire and extended coverage
policy will cover physical damage to or destruction of, the related Property
caused by fire, lightning, explosion, smoke, windstorm, hail, riot, strike and
civil commotion, subject to the conditions and exclusions particularized in each
policy. Because the standard hazard Insurance Policies relating to the Loans
will be underwritten by different hazard insurers and will cover Properties
located in various states, such policies will not contain identical terms and
conditions. The basic terms, however, generally will be determined by state law
and generally will be similar. Most such policies typically will not cover any
physical damage resulting from war, revolution, governmental actions, floods and
other water-related causes, earth movement (including earthquakes, landslides
and mudflows), nuclear reaction, wet or dry rot, vermin, rodents, insects or
domestic animals, theft and, in certain cases, vandalism. The foregoing list is
merely indicative of certain kinds of uninsured risks and is not intended to be
all inclusive. Uninsured risks not covered by a special hazard Insurance Policy
or other form of Enhancement will adversely affect distributions to Holders.
When a Property securing a Loan is located in a flood area identified by HUD
pursuant to the Flood Disaster Protection Act of 1973, as amended, the Servicer
will be required to cause flood insurance to be maintained with respect to such
Property, to the extent available.
 
     The standard hazard Insurance Policies covering Properties securing Loans
typically will contain a "coinsurance" clause, which in effect will require the
insured at all times to carry hazard insurance of a specified percentage
(generally 80% to 90%) of the full replacement value of the Property, including
any improvements on the Property, in order to recover the full amount of any
partial loss. If the insured's coverage falls below this specified percentage,
such clause will provide that the hazard insurer's liability in the event of
partial loss will not exceed the greater of (i) the actual cash value (the
replacement cost less physical depreciation) of the Property, including the
improvements, if any, damaged or destroyed or (ii) such proportion of the loss,
without deduction for depreciation, as the amount of insurance carried bears to
the specified percentage of the full replacement cost of such Property and
improvements. Since the amount of hazard insurance to be maintained on the
improvements securing the Loans declines as the Principal Balances owing thereon
decrease, and since the value of the Properties will fluctuate over time, the
effect of this requirement in the event of partial loss may be that hazard
Insurance Proceeds will be insufficient to restore fully the damage to the
affected Property.
 
     Unless otherwise specified in the related Prospectus Supplement, coverage
will be in an amount at least equal to the greater of (i) the amount necessary
to avoid the enforcement of any co-insurance clause contained in the policy or
(ii) the outstanding Principal Balance of the related Loan. Unless otherwise
specified in the related Prospectus Supplement, the Servicer will also maintain
on REO Property that secured a defaulted Loan and that has been acquired upon
foreclosure, deed in lieu of foreclosure or repossession, a standard hazard
Insurance Policy in an amount that is at least equal to the maximum insurable
value of such REO Property. No earthquake or other additional insurance will be
required of any obligor or will be maintained on REO Property acquired in
respect of a defaulted Loan, other than pursuant to such applicable laws and
regulations as shall at any time be in force and shall require such additional
insurance.
 
                                       35
<PAGE>   132
 
     Any amounts collected by the Servicer under any such Insurance Policies
(other than amounts to be applied to the restoration or repair of the Property,
released to the obligor in accordance with normal servicing procedures or used
to reimburse the Servicer for amounts to which it is entitled to reimbursement)
will be deposited into the Collection Account. In the event that the Servicer
obtains and maintains a blanket policy insuring against hazard losses on all of
the Loans, written by an insurer then acceptable to each Rating Agency that
assigns a rating to such Series, it will conclusively be deemed to have
satisfied its obligations to cause to be maintained a standard hazard Insurance
Policy for each Loan or related REO Property. This blanket policy may contain a
deductible clause, in which case the Servicer will be required, in the event
that there has been a loss that would have been covered by such policy absent
such deductible clause, to deposit into the Collection Account the amount not
otherwise payable under the blanket policy because of the application of such
deductible clause.
 
REALIZATION UPON DEFAULTED LOANS
 
     The Servicer will use its reasonable best efforts to foreclose upon,
repossess or otherwise comparably convert the ownership of the Properties
securing the related Loans as come into and continue in default and as to which
no satisfactory arrangements can be made for collection of delinquent payments.
In connection with such foreclosure or other conversion, the Servicer will
follow such practices and procedures as it deems necessary or advisable and as
are normal and usual in its servicing activities with respect to comparable
loans serviced by it. However, the Servicer will not be required to expend its
own funds in connection with any foreclosure or towards the restoration of the
Property unless it determines that (i) such restoration or foreclosure will
increase the Liquidation Proceeds in respect of the related Loan available to
the Holders after reimbursement to itself for such expenses and (ii) such
expenses will be recoverable by it either through Liquidation Proceeds or
Insurance Proceeds. Notwithstanding anything to the contrary herein, in the case
of a Trust Fund for which a REMIC election has been made, the Servicer will be
required to liquidate any Property acquired through foreclosure within two years
after the acquisition of the beneficial ownership of such Property. While the
holder of a Property acquired through foreclosure can often maximize its
recovery by providing financing to a new purchaser, the Trust Fund, if
applicable, will have no ability to do so and neither the Servicer nor the
Depositor will be required to do so.
 
     The Servicer may arrange with the obligor on a defaulted Loan a change in
the terms of such Loan (a "Modification") to the extent provided in the related
Prospectus Supplement. Such Modifications may only be entered into if they meet
the underwriting policies and procedures employed by the Servicer in servicing
receivables for its own account and meet the other conditions set forth in the
related Prospectus Supplement.
 
ENFORCEMENT OF DUE-ON-SALE CLAUSES
 
     Unless otherwise specified in the related Prospectus Supplement for a
Series, when any Property is about to be conveyed by the obligor, the Servicer
will, to the extent it has knowledge of such prospective conveyance and prior to
the time of the consummation of such conveyance, exercise its rights to
accelerate the maturity of the related Loan under the applicable "due-on-sale"
clause, if any, unless it reasonably believes that such clause is not
enforceable under applicable law or if the enforcement of such clause would
result in loss of coverage under any primary mortgage Insurance Policy. In such
event, the Servicer is authorized to accept from or enter into an assumption
agreement with the person to whom such property has been or is about to be
conveyed, pursuant to which such person becomes liable under the Loan and
pursuant to which the original obligor is released from liability and such
person is substituted as the obligor and becomes liable under the Loan. Any fee
collected in connection with an assumption will be retained by the Servicer as
additional servicing compensation. The terms of a Loan may not be changed in
connection with an assumption.
 
SERVICING COMPENSATION AND PAYMENT OF EXPENSES
 
     Except as otherwise provided in the related Prospectus Supplement, the
Servicer will be entitled to a periodic fee as servicing compensation (the
"Servicing Fee") in an amount to be determined as specified in the related
Prospectus Supplement. The Servicing Fee may be fixed or variable, as specified
in the related Prospectus Supplement. In addition, unless otherwise specified in
the related Prospectus Supplement, the
 
                                       36
<PAGE>   133
 
Servicer will be entitled to servicing compensation in the form of assumption
fees, late payment charges and similar items, or excess proceeds following
disposition of Property in connection with defaulted Loans.
 
     Unless otherwise specified in the related Prospectus Supplement, the
Servicer will pay certain expenses incurred in connection with the servicing of
the Loans, including, without limitation, the payment of the fees and expenses
of each applicable Trustee and independent accountants, payment of Security
Policy and Insurance Policy premiums, if applicable, and the cost of credit
support, if any, and payment of expenses incurred in preparation of reports to
Holders.
 
     When an obligor makes a principal prepayment in full between Due Dates on
the related Loan, the obligor will generally be required to pay interest on the
amount prepaid only to the date of prepayment. If and to the extent provided in
the related Prospectus Supplement, in order that one or more Classes of the
Holders of a Series will not be adversely affected by any resulting shortfall in
interest, the amount of the Servicing Fee may be reduced to the extent necessary
to include in the Servicer's remittance to the applicable Trustee for deposit
into the related Distribution Account an amount equal to one month's interest on
the related Loan (less the Servicing Fee). If the aggregate amount of such
shortfalls in a month exceeds the Servicing Fee for such month, a shortfall to
Holders may occur.
 
     Unless otherwise specified in the related Prospectus Supplement, the
Servicer will be entitled to reimbursement for certain expenses incurred by it
in connection with the liquidation of defaulted Loans. The related Holders will
suffer no loss by reason of such expenses to the extent expenses are covered
under related Insurance Policies or from excess Liquidation Proceeds. If claims
are either not made or paid under the applicable Insurance Policies or if
coverage thereunder has been exhausted, the related Holders will suffer a loss
to the extent that Liquidation Proceeds, after reimbursement of the Servicer's
expenses, are less than the Principal Balance of and unpaid interest on the
related Loan that would be distributable to Holders. In addition, the Servicer
will be entitled to reimbursement of expenditures incurred by it in connection
with the restoration of property securing a defaulted Loan, such right of
reimbursement being prior to the rights of the Holders to receive any related
Insurance Proceeds, Liquidation Proceeds or amounts derived from other
Enhancement. The Servicer is generally also entitled to reimbursement from the
Collection Account for Advances.
 
     Unless otherwise specified in the related Prospectus Supplement, the rights
of the Servicer to receive funds from the Collection Account for a Series,
whether as the Servicing Fee or other compensation, or for the reimbursement of
Advances, expenses or otherwise, are not subordinate to the rights of Holders of
such Series.
 
EVIDENCE AS TO COMPLIANCE
 
     If so specified in the related Prospectus Supplement, the applicable
Agreement for each Series will provide that each year, a firm of independent
public accountants will furnish a statement to the applicable Trustee to the
effect that such firm has examined certain documents and records relating to the
servicing of the Loans by the Servicer and that, on the basis of such
examination, such firm is of the opinion that the servicing has been conducted
in compliance with such Agreement, except for (i) such exceptions as such firm
believes to be immaterial and (ii) such other exceptions as are set forth in
such statement.
 
     If so specified in the related Prospectus Supplement, the applicable
Agreement for each Series will also provide for delivery to the applicable
Trustee for such Series of an annual statement signed by an officer of the
Servicer to the effect that the Servicer has fulfilled its obligations under
such Agreement throughout the preceding calendar year.
 
CERTAIN MATTERS REGARDING THE SERVICER
 
     The Servicer for each Series will be identified in the related Prospectus
Supplement. The Servicer may be an affiliate of the Depositor and may have other
business relationships with the Depositor and its affiliates.
 
     If an Event of Default occurs under either a Servicing Agreement or a
Pooling and Servicing Agreement, the Servicer may be replaced by the Trustee or
a successor Servicer. Unless otherwise specified in the related Prospectus
Supplement, such Events of Default and the rights of a Trustee upon such a
default under the Agreement for the related Series will be substantially similar
to those described under "The Agreements --
 
                                       37
<PAGE>   134
 
Events of Default; Rights Upon Events of Default -- Pooling and Servicing
Agreement; Servicing Agreement" herein.
 
     Unless otherwise specified in the related Prospectus Supplement, the
Servicer does not have the right to assign its rights and delegate its duties
and obligations under the related Agreement for each Series unless the successor
Servicer accepting such assignment or delegation (i) services similar loans in
the ordinary course of its business, (ii) is reasonably satisfactory to the
Trustee for the related Series, (iii) has a net worth of not less than the
amount specified in the related Prospectus Supplement, (iv) would not cause any
Rating Agency's rating of the Securities for such Series in effect immediately
prior to such assignment, sale or transfer to be qualified, downgraded or
withdrawn as a result of such assignment, sale or transfer and (v) executes and
delivers to the Trustee an agreement, in form and substance reasonably
satisfactory to the Trustee, that contains an assumption by such Servicer of the
due and punctual performance and observance of each covenant and condition to be
performed or observed by the Servicer under the related Agreement from and after
the date of such agreement. No such assignment will become effective until the
Trustee or a successor Servicer has assumed the servicer's obligations and
duties under the related Agreement. To the extent that the Servicer transfers
its obligations to a wholly-owned subsidiary or affiliate, such subsidiary or
affiliate need not satisfy the criteria set forth above; however, in such
instance, the assigning Servicer will remain liable for the servicing
obligations under the related Agreement. Any entity into which the Servicer is
merged or consolidated or any successor corporation resulting from any merger,
conversion or consolidation will succeed to the Servicer's obligations under the
related Agreement; provided, that such successor or surviving entity meets the
requirements for a successor Servicer set forth above.
 
     Except to the extent otherwise provided therein, each Agreement will
provide that neither the Servicer, nor any director, officer, employee or agent
of the Servicer, will be under any liability to the related Trust Fund, the
Depositor or the Holders for any action taken or for failing to take any action
in good faith pursuant to the related Agreement, or for errors in judgment;
provided, however, that neither the Servicer nor any such person will be
protected against any breach of warranty or representations made under such
Agreement or the failure to perform its obligations in compliance with any
standard of care set forth in such Agreement, or liability that would otherwise
be imposed by reason of willful misfeasance, bad faith or negligence in the
performance of their duties or by reason of reckless disregard of their
obligations and duties thereunder. Each Agreement will further provide that the
Servicer and any director, officer, employee or agent of the Servicer is
entitled to indemnification from the related Trust Fund and will be held
harmless against any loss, liability or expense incurred in connection with any
legal action relating to the Agreement or the Securities, other than any loss,
liability or expense incurred by reason of willful misfeasance, bad faith or
negligence in the performance of duties thereunder or by reason of reckless
disregard of obligations and duties thereunder. In addition, the related
Agreement will provide that the Servicer is not under any obligation to appear
in, prosecute or defend any legal action that is not incidental to its servicing
responsibilities under such Agreement that, in its opinion, may involve it in
any expense or liability. The Servicer may, in its discretion, undertake any
such action that it may deem necessary or desirable with respect to the related
Agreement and the rights and duties of the parties thereto and the interests of
the Holders thereunder. In such event the legal expenses and costs of such
action and any liability resulting therefrom may be expenses, costs, and
liabilities of the Trust Fund and the Servicer may be entitled to be reimbursed
therefor out of the Collection Account.
 
                                 THE AGREEMENTS
 
     The following summaries describe certain provisions of the Agreements. The
summaries do not purport to be complete and are subject to, and qualified in
their entirety by reference to, the provisions of the Agreements. Where
particular provisions or terms used in the Agreements are referred to, such
provisions or terms are as specified in the related Agreements.
 
ASSIGNMENT OF PRIMARY ASSETS
 
     General.  At the time of issuance of the Securities of a Series, the
Depositor will transfer, convey and assign to the Trust Fund all right, title
and interest of the Depositor in the Primary Assets and other property to be
transferred to the Trust Fund for a Series. Such assignment will include all
principal and interest due on or with respect to the Primary Assets after the
Cut-off Date specified in the related Prospectus Supplement
                                       38
<PAGE>   135
 
(except for any Retained Interests). The Trustee will, concurrently with such
assignment, execute and deliver the Securities.
 
     Assignment of Contracts. Unless otherwise specified in the related
Prospectus Supplement, the Depositor will, as to each Loan, deliver or cause to
be delivered to the Trustee, or, as specified in the related Prospectus
Supplement, a custodian on behalf of the Trustee (the "Custodian"), the Mortgage
Note endorsed without recourse to the order of the Trustee or in blank, the
original Mortgage with evidence of recording indicated thereon (except for any
Mortgage not returned from the public recording office, in which case a copy of
such Mortgage will be delivered, together with a certificate that the original
of such Mortgage was delivered to such recording office) and an assignment of
the Mortgage in recordable form. The Trustee, or, if so specified in the related
Prospectus Supplement, the Custodian, will hold such documents in trust for the
benefit of the Holders.
 
     Unless otherwise specified in the related Prospectus Supplement, the
Depositor will as to each Home Improvement Contract deliver or cause to be
delivered to the Trustee (or the Custodian) the original Home Improvement
Contract and copies of documents and instruments related to each Home
Improvement Contract and, other than in the case of unsecured Home Improvement
Contracts, the security interest in the property securing such Home Improvement
Contract. In order to give notice of the right, title and interest of Holders to
the Home Improvement Contracts, the Depositor will cause a UCC-1 financing
statement to be executed by the Depositor or the Seller identifying the Trustee
as the secured party and identifying all Home Improvement Contracts as
collateral. Unless otherwise specified in the related Prospectus Supplement, the
Home Improvement Contracts will not be stamped or otherwise marked to reflect
their assignment to the Trust. Therefore, if, through negligence, fraud or
otherwise, a subsequent purchaser were able to take physical possession of the
Home Improvement Contracts without notice of such assignment, the interest of
Holders in the Home Improvement Contracts could be defeated. See "Certain Legal
Aspects of the Loans -- The Home Improvement Contracts."
 
     With respect to Loans secured by Mortgages, if so specified in the related
Prospectus Supplement, the Depositor will, at the time of issuance of the
Securities, cause assignments to the Trustee of the Mortgages relating to the
Loans for a Series to be recorded in the appropriate public office for real
property records, except in states where, in the opinion of counsel acceptable
to the Trustee, such recording is not required to protect the Trustee's interest
in the related Loans. If specified in the related Prospectus Supplement, the
Depositor will cause such assignments to be so recorded within the time after
issuance of the Securities as is specified in the related Prospectus Supplement,
in which event, the Agreement may, as specified in the related Prospectus
Supplement, require the Depositor to repurchase from the Trustee any Loan the
related Mortgage of which is not recorded within such time, at the price
described below with respect to repurchases by reason of defective
documentation. Unless otherwise provided in the related Prospectus Supplement,
the enforcement of the repurchase obligation would constitute the sole remedy
available to the Holders or the Trustee for the failure of a Mortgage to be
recorded.
 
     Each Loan will be identified in a schedule appearing as an exhibit to the
related Agreement (the "Loan Schedule"). Such Loan Schedule will specify with
respect to each Loan: the original principal amount and unpaid Principal Balance
as of the Cut-off Date; the current Loan Rate; the current Scheduled Payment of
principal and interest; the maturity date, if any, of the related Mortgage Note;
if the Loan is an adjustable rate Loan, the Lifetime Rate Cap, if any, and the
current index.
 
     Assignment of Private Securities.  The Depositor will cause Private
Securities to be registered in the name of the PS Trustee (or its nominee or
correspondent). The PS Trustee (or its nominee or correspondent) will have
possession of any certificated Private Securities. Unless otherwise specified in
the related Prospectus Supplement, the PS Trustee will not be in possession of
or be assignee of record of any underlying assets for a Private Security. See
"The Trust Funds -- Private Securities" herein. Each Private Security will be
identified in a schedule appearing as an exhibit to the related Agreement (the
"Certificate Schedule"), which will specify the original principal amount,
Principal Balance as of the Cut-off Date, annual pass-through rate or interest
rate and maturity date for each Private Security conveyed to the Trust Fund. In
the Agreement, the Depositor will represent and warrant to the PS Trustee
regarding the Private Securities: (i) that the information contained in the
Certificate Schedule is true and correct in all material respects; (ii) that,
 
                                       39
<PAGE>   136
 
immediately prior to the conveyance of the Private Securities, the Depositor had
good title thereto, and was the sole owner thereof (subject to any Retained
Interest); (iii) that there has been no other sale by it of such Private
Securities; and (iv) that there is no existing lien, charge, security interest
or other encumbrance (other than any Retained Interest) on such Private
Securities.
 
     Repurchase and Substitution of Non-Conforming Primary Assets. Unless
otherwise provided in the related Prospectus Supplement, if any document in the
file relating to the Primary Assets delivered by the Depositor to the Trustee
(or Custodian) is found by the Trustee within 90 days of the execution of the
related Agreement (or promptly after the Trustee's receipt of any document
permitted to be delivered after the Closing Date) to be defective in any
material respect and the Depositor or Seller does not cure such defect within 90
days, or within such other period specified in the related Prospectus
Supplement, the Depositor or Seller will, not later than 90 days or within such
other period specified in the related Prospectus Supplement, after the Trustee's
notice to the Depositor or the Seller, as the case may be, of the defect,
repurchase the related Primary Asset or any property acquired in respect thereof
from the Trustee at a price equal to, unless otherwise specified in the related
Prospectus Supplement, (a) the lesser of (i) the Principal Balance of such
Primary Asset and (ii) the Trust Fund's federal income tax basis in the Primary
Asset and (b) accrued and unpaid interest to the date of the next scheduled
payment on such Primary Asset at the rate set forth in the related Agreement,
provided, however, the purchase price shall not be limited in (i) above to the
Trust Fund's federal income tax basis if the repurchase at a price equal to the
Principal Balance of such Primary Asset will not result in any prohibited
transaction tax under Section 860F(a) of the Code.
 
     If provided in the related Prospectus Supplement, the Depositor or Seller,
as the case may be, may, rather than repurchase the Primary Asset as described
above, remove such Primary Asset from the Trust Fund (the "Deleted Primary
Asset") and substitute in its place one or more other Primary Assets (each, a
"Qualifying Substitute Primary Asset"); provided, however, that (i) with respect
to a Trust Fund for which no REMIC election is made, such substitution must be
effected within 120 days of the date of initial issuance of the Securities and
(ii) with respect to a Trust Fund for which a REMIC election is made, after a
specified time period, the Trustee must have received a satisfactory opinion of
counsel that such substitution will not cause the Trust Fund to lose its status
as a REMIC or otherwise subject the Trust Fund to a prohibited transaction tax.
 
     Unless otherwise specified in the related Prospectus Supplement, any
Qualifying Substitute Primary Asset will have, on the date of substitution, (i)
a Principal Balance, after deduction of all Scheduled Payments due in the month
of substitution, not in excess of the Principal Balance of the Deleted Primary
Asset (the amount of any shortfall to be deposited to the Collection Account in
the month of substitution for distribution to Holders), (ii) an interest rate
not less than (and not more than 2% greater than) the interest rate of the
Deleted Primary Asset, (iii) a remaining term-to-stated maturity not greater
than (and not more than two years less than) that of the Deleted Primary Asset,
and will comply with all of the representations and warranties set forth in the
applicable Agreement as of the date of substitution.
 
     Unless otherwise provided in the related Prospectus Supplement, the
above-described cure, repurchase or substitution obligations constitute the sole
remedies available to the Holders or the Trustee for a material defect in a
document for a Primary Asset.
 
     The Depositor or another entity will make representations and warranties
with respect to Primary Assets for a Series. If the Depositor or such entity
cannot cure a breach of any such representations and warranties in all material
respects within the time period specified in the related Prospectus Supplement
after notification by the Trustee of such breach, and if such breach is of a
nature that materially and adversely affects the value of such Primary Asset,
the Depositor or such entity will be obligated to repurchase the affected
Primary Asset or, if provided in the related Prospectus Supplement, provide a
Qualifying Substitute Primary Asset therefor, subject to the same conditions and
limitations on purchases and substitutions as described above.
 
     The Depositor's only source of funds to effect any cure, repurchase or
substitution will be through the enforcement of the corresponding obligations,
if any, of the responsible originator or seller of such Primary Assets. See
"Special Considerations -- Limited Assets."

     No Holder of Securities of a Series, solely by virtue of such Holder's
status as a Holder, will have any right under the applicable Agreement for such
Series to institute any proceeding with respect to such Agreement, unless such
Holder previously has given to the applicable Trustee for such Series written
notice of default and unless the Holders of Securities evidencing not less than
51% of the aggregate voting rights of the Securities for such Series have made
written request upon the applicable Trustee to institute such proceeding in its
own name as Trustee thereunder and have offered to such Trustee reasonable
indemnity, and such Trustee for 60 days has neglected or refused to institute
any such proceeding.
 
REPORTS TO HOLDERS
 
     The applicable Trustee or other entity specified in the related Prospectus
Supplement will prepare and forward to each Holder on each Distribution Date, or
as soon thereafter as is practicable, a statement setting forth, to the extent
applicable to any Series, among other things:
 
          (i) the amount of principal distributed to Holders of the related
     Securities and the outstanding principal balance of such Securities
     following such distribution;
 
          (ii) the amount of interest distributed to Holders of the related
     Securities and the current interest on such Securities;
 
          (iii) the amount of (a) any overdue accrued interest included in such
     distribution, (b) any remaining overdue accrued interest with respect to
     such Securities or (c) any current shortfall in amounts to be distributed
     as accrued interest to Holders of such Securities;
 
          (iv) the amount of (a) any overdue payments of scheduled principal
     included in such distribution, (b) any remaining overdue principal amounts
     with respect to such Securities, (c) any current shortfall in receipt of
     scheduled principal payments on the related Primary Assets or (d) any
     realized losses or Liquidation Proceeds to be allocated as reductions in
     the outstanding principal balances of such Securities;
 
          (v) the amount received under any related Enhancement, and the
     remaining amount available under such Enhancement;
 
          (vi) the amount of any delinquencies with respect to payments on the
     related Primary Assets;
 
          (vii) the book value of any REO Property acquired by the related Trust
     Fund; and
 
          (viii) such other information as specified in the related Agreement.
 
     In addition, within a reasonable period of time after the end of each
calendar year, the applicable Trustee, unless otherwise specified in the related
Prospectus Supplement, will furnish to each Holder of record at any time during
such calendar year (a) the aggregate of amounts reported pursuant to (i), (ii)
and (iv)(d) above for such calendar year and (b) such information specified in
the related Agreement to enable Holders to prepare their tax returns including,
without limitation, the amount of original issue discount accrued on the
Securities, if applicable. Information in the Distribution Date and annual
statements provided to the Holders will not have been examined and reported upon
by an independent public accountant. However, the Servicer will provide to each
applicable Trustee a report by independent public accountants with respect to
the Servicer's servicing of the Loans. See "Servicing of Loans -- Evidence as to
Compliance" herein.
 
     If so specified in the Prospectus Supplement for a Series of Securities,
such Series or one or more Classes of such Series will be issued in book-entry
form. In such event, owners of beneficial interests in such Securities will not
be considered Holders and will not receive such reports directly from the
applicable Trustee. The applicable Trustee will forward such reports only to the
entity or its nominee that is the registered holder of the global certificate
that evidences such book-entry securities. Beneficial owners will receive such
reports from the participants and indirect participants of the applicable
book-entry system in accordance with the policies and procedures of such
entities.
 
EVENTS OF DEFAULT; RIGHTS UPON EVENT OF DEFAULT
 
     Pooling and Servicing Agreement; Servicing Agreement.  Unless otherwise
specified in the related Prospectus Supplement, Events of Default under the
Pooling and Servicing Agreement for each Series of
 
                                       41
<PAGE>   138
 
Certificates relating to Loans include (i) any failure by the Servicer to
deposit amounts in the Collection Account and Distribution Account(s) to enable
the applicable Trustee to distribute to Holders of such Series any required
payment, which failure continues unremedied for the number of days specified in
the related Prospectus Supplement after the giving of written notice of such
failure to the Servicer by the applicable Trustee for such Series, or to the
Servicer and such Trustee by the Holders of such Series evidencing not less than
25% of the aggregate voting rights of the Securities for such Series, (ii) any
failure by the Servicer duly to observe or perform in any material respect any
other of its covenants or agreements in the applicable Agreement that continues
unremedied for the number of days specified in the related Prospectus Supplement
after the giving of written notice of such failure to the Servicer by the
applicable Trustee, or to the Servicer and such Trustee by the Holders of such
Series evidencing not less than 25% of the aggregate voting rights of the
Securities for such Series, and (iii) certain events of insolvency, readjustment
of debt, marshalling of assets and liabilities or similar proceedings and
certain actions by the Servicer indicating its insolvency, reorganization or
inability to pay its obligations.
 
     So long as an Event of Default remains unremedied under the applicable
Agreement for a Series of Securities relating to the servicing of Loans, unless
otherwise specified in the related Prospectus Supplement, the Trustee for such
Series or Holders of Securities of such Series evidencing not less than 51% of
the aggregate voting rights of the Securities for such Series may terminate all
of the rights and obligations of the Servicer as servicer under the applicable
Agreement (other than its right to recovery of other expenses and amounts
advanced pursuant to the terms of such Agreement, which rights the Servicer will
retain under all circumstances), whereupon the Trustee will succeed to all the
responsibilities, duties and liabilities of the Servicer under such Agreement
and will be entitled to reasonable servicing compensation not to exceed the
applicable servicing fee, together with other servicing compensation in the form
of assumption fees, late payment charges or otherwise as provided in such
Agreement.
 
     In the event that the Trustee is unwilling or unable so to act, it may
select, or petition a court of competent jurisdiction to appoint, a finance
institution, bank or loan servicing institution with a net worth specified in
the related Prospectus Supplement to act as successor Servicer under the
provisions of the applicable Agreement. The successor Servicer would be entitled
to reasonable servicing compensation in an amount not to exceed the Servicing
Fee as set forth in the related Prospectus Supplement, together with other
servicing compensation in the form of assumption fees, late payment charges or
otherwise, as provided in such Agreement.
 
     During the continuance of any Event of Default of a Servicer under an
Agreement for a Series of Securities, the applicable Trustee for such Series
will have the right to take action to enforce its rights and remedies and to
protect and enforce the rights and remedies of the Holders of such Series, and,
unless otherwise specified in the related Prospectus Supplement, Holders of
Securities evidencing not less than 51% of the aggregate voting rights of the
Securities for such Series may direct the time, method and place of conducting
any proceeding for any remedy available to the applicable Trustee or exercising
any trust or power conferred upon such Trustee. However, the applicable Trustee
will not be under any obligation to pursue any such remedy or to exercise any of
such trusts or powers unless such Holders have offered such Trustee reasonable
security or indemnity against the cost, expenses and liabilities that may be
incurred by such Trustee therein or thereby. The applicable Trustee may decline
to follow any such direction if such Trustee determines that the action or
proceeding so directed may not lawfully be taken or would involve it in personal
liability or be unjustly prejudicial to the non-assenting Holders.
 
     Indenture.  Unless otherwise specified in the related Prospectus
Supplement, Events of Default under the Indenture for each Series of Notes
include: (i) a default for thirty (30) days or more in the payment of any
principal of or interest on any Note of such Series; (ii) failure to perform any
other covenant of the Depositor or the Trust Fund in the Indenture that
continues for a period of sixty (60) days after notice thereof is given in
accordance with the procedures described in the related Prospectus Supplement;
(iii) any representation or warranty made by the Depositor or the Trust Fund in
the Indenture or in any certificate or other writing delivered pursuant thereto
or in connection therewith with respect to or affecting such Series having been
incorrect in a material respect as of the time made, and such breach is not
cured within sixty (60) days after notice thereof is given in accordance with
the procedures described in the related Prospectus
 
                                       42
<PAGE>   139
 
Supplement; (iv) certain events of bankruptcy, insolvency, receivership or
liquidation of the Depositor or the Trust Fund; or (v) any other Event of
Default provided with respect to Notes of that Series.
 
     If an Event of Default with respect to the Notes of any Series at the time
outstanding occurs and is continuing, either the Indenture Trustee or the
Holders of a majority of the then-aggregate outstanding amount of the Notes of
such Series may declare the principal amount (or, if the Notes of that Series
are Zero Coupon Securities, such portion of the principal amount as may be
specified in the terms of that Series, as provided in the related Prospectus
Supplement) of all the Notes of such Series to be due and payable immediately.
Such declaration may, under certain circumstances, be rescinded and annulled by
the Holders of a majority in aggregate outstanding amount of the Notes of such
Series.
 
     If, following an Event of Default with respect to any Series of Notes, the
Notes of such Series have been declared to be due and payable, the Indenture
Trustee may, in its discretion, notwithstanding such acceleration, elect to
maintain possession of the collateral securing the Notes of such Series and to
continue to apply distributions on such collateral as if there had been no
declaration of acceleration if such collateral continues to provide sufficient
funds for the payment of principal of and interest on the Notes of such Series
as they would have become due if there had not been such a declaration. In
addition, the Indenture Trustee may not sell or otherwise liquidate the
collateral securing the Notes of a Series following an Event of Default other
than a default in the payment of any principal of or interest on any Note of
such Series for thirty (30) days or more, unless (a) the Holders of 100% of the
then-aggregate outstanding amount of the Notes of such Series consent to such
sale, (b) the proceeds of such sale or liquidation are sufficient to pay in full
the principal of and accrued interest due and unpaid on the outstanding Notes of
such Series at the date of such sale or (c) the Indenture Trustee determines
that such collateral would not be sufficient on an ongoing basis to make all
payments on such Notes as such payments would have become due if such Notes had
not been declared due and payable, and the Indenture Trustee obtains the consent
of the Holders of 66 2/3% of the then-aggregate outstanding amount of the Notes
of such Series.
 
     In the event that the Indenture Trustee liquidates the collateral in
connection with an Event of Default involving a default for thirty (30) days or
more in the payment of principal of or interest on the Notes of a Series, the
Indenture provides that the Indenture Trustee will have a prior lien on the
proceeds of any such liquidation for unpaid fees and expenses. As a result, upon
the occurrence of such an Event of Default, the amount available for
distribution to the Noteholders may be less than would otherwise be the case.
However, the Indenture Trustee may not institute a proceeding for the
enforcement of its lien except in connection with a proceeding for the
enforcement of the lien of the Indenture for the benefit of the Noteholders
after the occurrence of such an Event of Default.
 
     Unless otherwise specified in the related Prospectus Supplement, in the
event the principal of the Notes of a Series is declared due and payable, as
described above, the Holders of any such Notes issued at a discount from par may
be entitled to receive no more than an amount equal to the unpaid principal
amount thereof less the amount of such discount that is unamortized.
 
     Subject to the provisions of the Indenture relating to the duties of the
Indenture Trustee, in case an Event of Default shall occur and be continuing
with respect to a Series of Notes, the Indenture Trustee will be under no
obligation to exercise any of the rights or powers under the Indenture at the
request or direction of any of the Holders of Notes of such Series, unless such
Holders offered to the Indenture Trustee security or indemnity satisfactory to
it against the costs, expenses and liabilities that might be incurred by it in
complying with such request or direction. Subject to such provisions for
indemnification and certain limitations contained in the Indenture, the Holders
of a majority of the then-aggregate outstanding amount of the Notes of such
Series shall have the right to direct the time, method and place of conducting
any proceeding for any remedy available to the Indenture Trustee or exercising
any trust or power conferred on the Indenture Trustee with respect to the Notes
of such Series, and the Holders of a majority of the then-aggregate outstanding
amount of the Notes of such Series may, in certain cases, waive any default with
respect thereto, except a default in the payment of principal or interest or a
default in respect of a covenant or provision of the Indenture that cannot be
modified without the waiver or consent of all the Holders of the outstanding
Notes of such Series affected thereby.

THE TRUSTEES
 
     The identity of the commercial bank, savings and loan association or trust
company named as the Trustee or Indenture Trustee, as the case may be, for each
Series of Securities will be set forth in the related Prospectus Supplement.
Entities serving as Trustee may have normal banking relationships with the
Depositor or the Servicer. In addition, for the purpose of meeting the legal
requirements of certain local jurisdictions, each Trustee will have the power to
appoint co-trustees or separate trustees. In the event of such appointment, all
rights, powers, duties and obligations conferred or imposed upon the applicable
Trustee by the Agreement relating to such Series will be conferred or imposed
upon such Trustee and each such separate trustee or co-trustee jointly, or, in
any jurisdiction in which such Trustee shall be incompetent or unqualified to
perform certain acts, singly upon such separate trustee or co-trustee who will
exercise and perform such rights, powers, duties and obligations solely at the
direction of the applicable Trustee. The applicable Trustee may also appoint
agents to perform any of the responsibilities of such Trustee, which agents will
have any or all of the rights, powers, duties and obligations of such Trustee
conferred on them by such appointment; provided, that the applicable Trustee
will continue to be responsible for its duties and obligations under the
Agreement.
 
DUTIES OF TRUSTEES
 
     No Trustee will make any representations as to the validity or sufficiency
of the related Agreement, the Securities or of any Primary Asset or related
documents. If no Event of Default (as defined in the related Agreement) has
occurred, the applicable Trustee will be required to perform only those duties
specifically required of it under such Agreement. Upon receipt of the various
certificates, statements, reports or other instruments required to be furnished
to it, the applicable Trustee will be required to examine them to determine
whether they are in the form required by the related Agreement. However, such
Trustee will not be responsible for the accuracy or content of any such
documents furnished to it by the Holders or the Servicer under the related
Agreement.
 
     Each Trustee may be held liable for its own negligent action or failure to
act, or for its own misconduct; provided, however, that no Trustee will be
personally liable with respect to any action taken, suffered or omitted to be
taken by it in good faith in accordance with the direction of the related
Holders in an Event of Default. No Trustee will be required to expend or risk
its own funds or otherwise incur any financial liability in the performance of
any of its duties under the related Agreement, or in the exercise of any of its
rights or powers, if it has reasonable grounds for believing that repayment of
such funds or adequate indemnity against such risk or liability is not
reasonably assured to it.
 
RESIGNATION OF TRUSTEES
 
     Each Trustee may, upon written notice to the Depositor, resign at any time,
in which event the Depositor will be obligated to use its best efforts to
appoint a successor Trustee. If no successor Trustee has been appointed and has
accepted such appointment within 30 days after the giving of such notice of
resignation, the resigning Trustee may petition any court of competent
jurisdiction for appointment of a successor Trustee. Each Trustee may also be
removed at any time (i) if such Trustee ceases to be eligible to continue as
such under the related Agreement, (ii) if such Trustee becomes insolvent or
(iii) by the Holders of Securities evidencing over 50% of the aggregate voting
rights of the Securities in the Trust Fund upon written notice to the applicable
Trustee and to the Depositor. Any resignation or removal of a Trustee and
appointment of a successor Trustee will not become effective until acceptance of
the appointment by the successor Trustee.
 
AMENDMENT OF AGREEMENT
 
     Unless otherwise specified in the Prospectus Supplement, the Agreement for
each Series of Securities may be amended by the Depositor, the Servicer (with
respect to a Series relating to Loans), and the applicable Trustee with respect
to such Series, without notice to or consent of the Holders (i) to cure any
ambiguity, (ii) to correct any defective provisions or to correct or supplement
any provision therein, (iii) to add to the duties of the Depositor, the
applicable Trustee or the Servicer, (iv) to add any other provisions with
respect to matters or questions arising under such Agreement or related
Enhancement, (v) to add or amend any provisions of such Agreement as required by
a Rating Agency in order to maintain or improve the rating of the Securities (it
being understood that none of the Depositor, the Seller, the Servicer or any
Trustee is
 
                                       44
<PAGE>   141
 
obligated to maintain or improve such rating), or (vi) to comply with any
requirements imposed by the Code; provided, that any such amendment except
pursuant to clause (vi) above will not adversely affect in any material respect
the interests of any Holders of such Series, as evidenced by an opinion of
counsel delivered to the applicable Trustee. Any such amendment except pursuant
to clause (vi) above shall be deemed not to adversely affect in any material
respect the interests of any Holder if the applicable Trustee receives written
confirmation from each Rating Agency rating such Securities that such amendment
will not cause such Rating Agency to reduce the then-current rating thereof.
Unless otherwise specified in the Prospectus Supplement, each Agreement for each
Series may also be amended by the applicable Trustee, the Servicer, if
applicable, and the Depositor with respect to such Series with the consent of
the Holders possessing not less than 66 2/3% of the aggregate outstanding
principal amount of the Securities of such Series or, if only certain Classes of
such Series are affected by such amendment, 66 2/3% of the aggregate outstanding
principal amount of the Securities of each Class of such Series 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 modifying in any
manner the rights of Holders of such Series; provided, however, that no such
amendment may (a) reduce the amount or delay the timing of payments on any
Security without the consent of the Holder of such Security; or (b) reduce the
aforesaid percentage of the aggregate outstanding principal amount of Securities
of each Class, the Holders of which are required to consent to any such
amendment, without the consent of the Holders of 100% of the aggregate
outstanding principal amount of each Class of Securities affected thereby.
 
VOTING RIGHTS
 
     The related Prospectus Supplement will set forth the method of determining
allocation of voting rights with respect to a Series.
 
LIST OF HOLDERS
 
     Upon written request of three or more Holders of record of a Series for
purposes of communicating with other Holders with respect to their rights under
the Agreement, which request is accompanied by a copy of the communication such
Holders propose to transmit, the applicable Trustee will afford such Holders
access during business hours to the most recent list of Holders of that Series
held by such Trustee.
 
     No Agreement will provide for the holding of any annual or other meeting of
Holders.
 
BOOK-ENTRY SECURITIES
 
     If specified in the Prospectus Supplement for a Series of Securities, such
Series or one or more Classes of such Series may be issued in book-entry form.
In such event, beneficial owners of such Securities will not be considered
"Holders" under the Agreements and may exercise the rights of Holders only
indirectly through the participants in the applicable book-entry system.
 
REMIC ADMINISTRATOR
 
     For any Series with respect to which a REMIC election is made, preparation
of certain reports and certain other administrative duties with respect to the
Trust Fund may be performed by a REMIC administrator, who may be an affiliate of
the Depositor.
 
TERMINATION
 
     Pooling and Servicing Agreement; Trust Agreement.  The obligations created
by the Pooling and Servicing Agreement or Trust Agreement for a Series will
terminate upon the distribution to Holders of all amounts distributable to them
pursuant to such Agreement under the circumstances described in the related
Prospectus Supplement. See "Description of the Securities -- Optional
Redemption, Purchase or Termination" herein.
 
     Indenture.  The Indenture will be discharged with respect to a Series of
Notes (except with respect to certain continuing rights specified in the
Indenture) upon the delivery to the Indenture Trustee for cancellation of all
the Notes of such Series or, with certain limitations, upon deposit with the
Indenture Trustee of funds sufficient for the payment in full of all of the
Notes of such Series.
 
                                       45
<PAGE>   142
 
     In addition to such discharge with certain limitations, the Indenture will
provide that, if so specified with respect to the Notes of any Series, the
related Trust Fund will be discharged from any and all obligations in respect of
the Notes of such Series (except for certain obligations relating to temporary
Notes and exchange of Notes, to register the transfer of or exchange Notes of
such Series, to replace stolen, lost or mutilated Notes of such Series, to
maintain paying agencies and to hold monies for payment in trust) upon the
deposit with the Indenture Trustee, in trust, of money and/or direct obligations
of or obligations guaranteed by the United States of America that, through the
payment of interest and principal in respect thereof in accordance with their
terms, will provide money in an amount sufficient to pay the principal of and
each installment of interest on the Notes of such Series on the Final Scheduled
Distribution Date for such Notes and any installment of interest on such Notes
in accordance with the terms of the Indenture and the Notes of such Series. In
the event of any such defeasance and discharge of Notes of such Series, Holders
of Notes of such Series would be able to look only to such money and/or direct
obligations for payment of principal of and interest on, if any, their Notes
until maturity.
 
                       CERTAIN LEGAL ASPECTS OF THE LOANS
 
     The following discussion contains summaries of certain legal aspects of
mortgage loans, home improvement installment sales contracts and home
improvement installment loan agreements that are general in nature. Because
certain of such legal aspects are governed by applicable state law (which laws
may differ substantially), the summaries do not purport to be complete nor
reflect the laws of any particular state, nor encompass the laws of all states
in which the properties securing the Loans are situated.
 
MORTGAGES
 
     The Loans for a Series will, and certain Home Improvement Contracts for a
Series may, be secured by either mortgages or deeds of trust or deeds to secure
debt (such Mortgage Loans and Home Improvement Contracts are hereinafter
referred to in this section as "mortgage loans"), depending upon the prevailing
practice in the state in which the property subject to a mortgage loan is
located. The filing of a mortgage, deed of trust or deed to secure debt creates
a lien or title interest upon the real property covered by such instrument and
represents the security for the repayment of an obligation that is customarily
evidenced by a promissory note. It is not prior to the lien for real estate
taxes and assessments or other charges imposed under governmental police powers
and may also be subject to other liens pursuant to the laws of the jurisdiction
in which the Mortgaged Property is located. Priority with respect to such
instruments depends on their terms, the knowledge of the parties to the mortgage
and generally on the order of recording with the applicable state, county or
municipal office. There are two parties to a mortgage, the mortgagor, who is the
borrower/property owner or the land trustee (as described below), and the
mortgagee, who is the lender. Under the mortgage instrument, the mortgagor
delivers to the mortgagee a note or bond and the mortgage. In the case of a land
trust, there are three parties because title to the property is held by a land
trustee under a land trust agreement of which the borrower/property owner is the
beneficiary; at origination of a mortgage loan, the borrower executes a separate
undertaking to make payments on the mortgage note. A deed of trust transaction
normally has three parties: the trustor, who is the borrower/property owner; the
beneficiary, who is the lender; and the trustee, a third-party grantee. Under a
deed of trust, the trustor grants the property, irrevocably until the debt is
paid, in trust, generally with a power of sale, to the trustee to secure payment
of the obligation. The mortgagee's authority under a mortgage and the trustee's
authority under a deed of trust are governed by the law of the state in which
the real property is located, the express provisions of the mortgage or deed of
trust, and, in some cases, in deed of trust transactions, the directions of the
beneficiary.
 
FORECLOSURE ON MORTGAGES
 
     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 defendant. 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
 
                                       46
<PAGE>   143
 
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
nonjudicial power of sale.
 
     Foreclosure of a deed of trust is generally accomplished by a nonjudicial
trustee's sale under a specific provision in the deed of trust that authorizes
the trustee to sell the property 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 notice of sale. In addition, the trustee in
some states must provide notice to any other individual having an interest 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. The trustor, borrower, or any 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. Generally, state law controls the
amount of foreclosure expenses and costs, including attorney's fees, which may
be recovered by a lender. If the deed of trust is not reinstated, 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, recorded
and sent to all parties having an interest in the real property.
 
     An action to foreclose a mortgage is an action to recover the mortgage debt
by enforcing the mortgagee's rights under the mortgage. It is regulated by
statutes and rules and subject throughout to the court's equitable powers.
Generally, a mortgagor is bound by the terms of the related mortgage note and
the mortgage as made and cannot be relieved from his default if the mortgagee
has exercised his rights in a commercially reasonable manner. However, since a
foreclosure action historically was equitable in nature, the court may exercise
equitable powers to relieve a mortgagor of a default and deny the mortgagee
foreclosure on proof that either the mortgagor's default was neither willful nor
in bad faith or the mortgagee's action established a waiver, fraud, bad faith,
or oppressive or unconscionable conduct such as to warrant a court of equity to
refuse affirmative relief to the mortgagee. Under certain circumstances a court
of equity may relieve the mortgagor from an entirely technical default where
such default was not willful.
 
     A foreclosure action is subject to most of the delays and expenses of other
lawsuits if defenses or counterclaims are interposed, sometimes requiring up to
several years to complete. Moreover, a non-collusive, regularly conducted
foreclosure sale may be challenged as a fraudulent conveyance, regardless of the
parties' intent, if a court determines that the sale was for less than fair
consideration and such sale occurred while the mortgagor was insolvent and
within one year (or within the state statute of limitations if the trustee in
bankruptcy elects to proceed under state fraudulent conveyance law) of the
filing of bankruptcy. Similarly, a suit against the debtor on the related
mortgage note may take several years and, generally, is a remedy alternative to
foreclosure, the mortgagee being precluded from pursuing both at the same time.
 
     In the case of foreclosure under either a mortgage or a deed of trust, the
sale by the referee or other designated officer or by the trustee is a public
sale. However, because of the difficulty potential third party purchasers at the
sale 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 uncommon for a third party to purchase the property at a
foreclosure sale. Rather, it is common for the lender to purchase the property
from the trustee or referee for an amount that may be equal to the unpaid
principal amount of the mortgage note secured by the mortgage or deed of trust
plus accrued and unpaid interest and the expenses of foreclosure, in which event
the mortgagor's debt will be extinguished or the lender may purchase for a
lesser amount in order to preserve its right against a borrower to seek a
deficiency judgment in states where such a judgment is available. 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, paying taxes and making such repairs at
its own expense as are necessary to render the property suitable for sale. The
lender will commonly obtain the services of a real estate broker and pay the
broker's commission in
 
                                       47

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. Any loss may be reduced by the receipt of any
mortgage guaranty Insurance Proceeds.
 
ENVIRONMENTAL RISKS
 
     Federal, state and local laws and regulations impose a wide range of
requirements on activities that may affect the environment, health and safety.
These include laws and regulations governing air pollutant emissions, hazardous
and toxic substances, impacts to wetlands, leaks from underground storage tanks
and the management, removal and disposal of lead- and asbestos-containing
materials. In certain circumstances, these laws and regulations impose
obligations on the owners or operators of residential properties such as those
subject to the Loans. The failure to comply with such laws and regulations may
result in fines and penalties.
 
     Moreover, under various federal, state and local laws and regulations, an
owner or operator of real estate may be liable for the costs of addressing
hazardous substances on, in or beneath such property and related costs. Such
liability may be imposed without regard to whether the owner or operator knew
of, or was responsible for, the presence of such substances, and could exceed
the value of the property and the aggregate assets of the owner or operator. In
addition, persons who transport or dispose of hazardous substances, or arrange
for the transportation, disposal or treatment of hazardous substances, at
off-site locations may also be held liable if there are releases or threatened
releases of hazardous substances at such off-site locations.
 
     In addition, under the laws of some states and under the Federal
Comprehensive Environmental Response, Compensation and Liability Act ("CERCLA"),
contamination of property may give rise to a lien on the property to assure the
payment of the costs of clean-up. In several states, such a lien has priority
over the lien of an existing mortgage against such property. Under CERCLA, such
a lien is subordinate to pre-existing, perfected security interests.
 
     Under the laws of some states, and under CERCLA, there is a possibility
that a lender may be held liable as an "owner or operator" for costs of
addressing releases or threatened releases of hazardous substances at a
property, regardless of whether or not the environmental damage or threat was
caused by a current or prior owner or operator. CERCLA and some state laws
provide an exemption from the definition of "owner or operator" for a secured
creditor who, without "participating in the management" of a facility, holds
indicia of ownership primarily to protect its security interest in the facility.
The Solid Waste Disposal Act (the "SWDA") provides similar protection to secured
creditors in connection with liability for releases of petroleum from certain
underground storage tanks. However, if a lender "participates in the management"
of the facility in question or is found not to have held its interest primarily
to protect a security interest, the lender may forfeit its secured creditor
exemption status.
 
     A regulation promulgated by the U.S. Environmental Protection Agency (the
"EPA") in April 1992 attempted to clarify the activities in which lenders could
engage both prior to and subsequent to foreclosure of a security interest
without forfeiting the secured creditor exemption under CERCLA. The rule was
struck down in 1994 by the United States Court of Appeals for the District of
Columbia Circuit in Kelley ex rel State of Michigan v. Environmental Protection
Agency, 15 F.3d 1100 (D.C Cir. 1994), reh'g denied, 25 F.3d 1088, cert. denied
sub nom. Am. Bankers Ass'n v. Kelley, 115 S.Ct. 900 (1995). Another EPA
regulation promulgated in 1995 clarifies the activities in which lenders may
engage without forfeiting the secured creditor exemption under the underground
storage tank provisions of the SWDA. That regulation has not been struck down.
 
     On September 30, 1996, Congress amended both CERCLA and the SWDA to provide
additional clarification regarding the scope of the lender liability exemptions
under the two statutes. Among other things, the 1996 amendments specify the
circumstances under which a lender will be protected by the CERCLA and SWDA
exemptions, both while the borrower is still in possession of the secured
property and following foreclosure on the secured property.
 
     Generally, the amendments state that a lender who holds indicia of
ownership primarily to protect a security interest in a facility will be
considered to participate in management only if, while the borrower is still in
possession of the facility encumbered by the security interest, the lender (i)
exercises decision-making control over environmental compliance related to the
facility such that the lender has undertaken responsibil-
                                       48
<PAGE>   145
 
ity for hazardous substance handling or disposal practices related to the
facility or (ii) exercises control at a level comparable to that of a manager of
the facility such that the lender has assumed or manifested responsibility for
(a) overall management of the facility encompassing daily decision-making with
respect to environmental compliance or (b) overall or substantially all of the
operational functions (as distinguished from financial or administrative
functions) of the facility other than the function of environmental compliance.
The amendments also specify certain activities that are not considered to be
"participation in management," including monitoring or enforcing the terms of
the extension of credit or security interest, inspecting the facility, and
requiring a lawful means of addressing the release or threatened release of a
hazardous substance.
 
     The 1996 amendments also specify that a lender who did not participate in
management of a facility prior to foreclosure will not be considered an "owner
or operator," even if the lender forecloses on the facility and after
foreclosure sells or liquidates the facility, maintains business activities,
winds up operations, undertakes an appropriate response action, or takes any
other measure to preserve, protect, or prepare the facility prior to sale or
disposition, if the lender seeks to sell or otherwise divest the facility at the
earliest practicable, commercially reasonable time, on commercially reasonable
terms, taking into account market conditions and legal and regulatory
requirements.
 
     The CERCLA and SWDA lender liability amendments specifically address the
potential liability of lenders who hold mortgages or similar conventional
security interests in real property, such as the Trust Fund does in connection
with the Mortgage Loans and the Home Improvement Contracts.
 
     If a lender is or becomes liable under CERCLA, it may be authorized to
bring a statutory action for contribution against any other "responsible
parties," including a previous owner or operator. However, such persons or
entities may be bankrupt or otherwise judgment proof, and the costs associated
with environmental cleanup and related actions may be substantial. Moreover,
some state laws imposing liability for addressing hazardous substances do not
contain exemptions from liability for lenders. Whether the costs of addressing a
release or threatened release at a property pledged as collateral for one of the
Loans would be imposed on the Trust Fund, and thus occasion a loss to the
Holders, therefore depends on the specific factual and legal circumstances at
issue.
 
RIGHTS OF REDEMPTION
 
     In some states, after sale pursuant to a deed of trust or foreclosure of a
mortgage, the trustor or mortgagor and foreclosed junior lienors are given a
statutory period in which to redeem the property from the foreclosure sale. The
right of redemption should be distinguished from the equity of redemption, which
is a non-statutory right that must be exercised prior to the foreclosure sale.
In some states, redemption may occur only upon payment of the entire principal
balance of the loan, accrued interest and expenses of foreclosure. In other
states, redemption may be authorized if the former borrower pays only a portion
of the sums due. The effect of a statutory 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 foreclosure or sale
under a deed of trust. Consequently, the practical effect of a right of
redemption is to force the lender to retain the property and pay the expenses of
ownership until the redemption period has run. In some states, there is no right
to redeem property after a trustee's sale under a deed of trust.
 
JUNIOR MORTGAGES; RIGHTS OF SENIOR MORTGAGES
 
     The Mortgage Loans comprising or underlying the Primary Assets included in
the Trust Fund for a Series will be secured by Mortgages or deeds of trust,
which may be second or more junior mortgages to other mortgages held by other
lenders or institutional investors. The rights of the Trust Fund (and therefore
the Holders), as mortgagee under a junior mortgage, are subordinate to those of
the mortgagee under the senior mortgage, including the prior rights of the
senior mortgagee to receive hazard insurance and condemnation proceeds and to
cause the property securing the mortgage loan to be sold upon default of the
mortgagor, thereby extinguishing the junior mortgagee's lien unless the junior
mortgagee asserts its subordinate interest in the property in foreclosure
litigation and, possibly, satisfies the defaulted senior mortgage. A junior
mortgagee may satisfy a defaulted senior loan in full and, in some states, may
cure such default and bring the senior loan current, in either event adding the
amounts expended to the balance due on the junior loan. In most states,
                                       49
<PAGE>   146
 
absent a provision in the mortgage or deed of trust, no notice of default is
required to be given to a junior mortgagee.
 
     The standard form of the mortgage used by most institutional lenders
confers on the mortgagee the right both to receive all proceeds collected under
any hazard Insurance Policy and all awards made in connection with condemnation
proceedings, and to apply such proceeds and awards to any indebtedness secured
by the mortgage, in such order as the mortgagee may determine. Thus, in the
event improvements on the property are damaged or destroyed by fire or other
casualty, or in the event the property is taken by condemnation, the mortgagee
or beneficiary under underlying senior mortgages will have the prior right to
collect any Insurance Proceeds payable under a hazard Insurance Policy and any
award of damages in connection with the condemnation and to apply the same to
the indebtedness secured by the senior mortgages. Proceeds in excess of the
amount of senior mortgage indebtedness, in most cases, may be applied to the
indebtedness of a junior mortgage.
 
     Another provision sometimes found in the form of the mortgage or deed of
trust used by institutional lenders obligates the mortgagor to pay before
delinquency all taxes and assessments on the property and, when due, all
encumbrances, charges and liens on the property that appear prior to the
mortgage or deed of trust, to provide and maintain fire insurance on the
property, to maintain and repair the property and not to commit or permit any
waste thereof, and to appear in and defend any action or proceeding purporting
to affect the property or the rights of the mortgagee under the mortgage. Upon a
failure of the mortgagor to perform any of these obligations, the mortgagee is
given the right under certain mortgages to perform the obligation itself, at its
election, with the mortgagor agreeing to reimburse the mortgagee for any sums
expended by the mortgagee on behalf of the mortgagor. All sums so expended by
the mortgagee become part of the indebtedness secured by the mortgage.
 
ANTI-DEFICIENCY LEGISLATION AND OTHER LIMITATIONS ON LENDERS
 
     Certain states have imposed statutory prohibitions that limit the remedies
of a beneficiary under a deed of trust or a mortgagee under a mortgage. 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 former
borrower equal in most cases to the difference between the net amount realized
upon the public sale of the real property and the amount due to the lender.
Other statutes 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. Finally, other statutory provisions 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 the public sale. The purpose of these statutes is generally 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 addition to laws limiting or prohibiting deficiency judgments, numerous
other statutory provisions, including the federal bankruptcy laws, the Federal
Soldiers' and Sailors' Relief Act and state laws affording relief to debtors,
may interfere with or affect the ability of the secured lender to realize upon
collateral and/or enforce a deficiency judgment. For example, with respect to
federal bankruptcy law, the filing of a petition acts as a stay against the
enforcement of remedies for collection of a debt. Moreover, a court with federal
bankruptcy jurisdiction may permit a debtor through a Chapter 13 Bankruptcy Code
rehabilitative plan to cure a monetary default with respect to a loan on a
debtor's residence by paying arrearages within a reasonable time period and
reinstating the original loan payment schedule even though the lender
accelerated the loan and the lender has taken all steps to realize upon his
security (provided no sale of the property has yet occurred) prior to the filing
of the debtor's Chapter 13 petition. Some courts with federal bankruptcy
 
                                       50
<PAGE>   147
 
jurisdiction have approved plans, based on the particular facts of the
reorganization case, that effected the curing of a loan default by permitting
the obligor to pay arrearages over a number of years.
 
     Courts with federal bankruptcy jurisdiction have also indicated that the
terms of a mortgage loan may be modified if the borrower has filed a petition
under Chapter 13. These courts have suggested that such modifications may
include reducing the amount of each monthly payment, changing the rate of
interest, altering the repayment schedule and reducing the lender's security
interest to the value of the residence, thus leaving the lender a general
unsecured creditor for the difference between the value of the residence and the
outstanding balance of the loan. Federal bankruptcy law and limited case law
indicate that the foregoing modifications could not be applied to the terms of a
loan secured by property that is the principal residence of the debtor. In all
cases, the secured creditor is entitled to the value of its security plus
post-petition interest, attorney's fees and costs to the extent the value of the
security exceeds the debt.
 
     In a Chapter 11 case under the Bankruptcy Code, the lender is precluded
from foreclosing without authorization from the bankruptcy court. The lender's
lien may be transferred to other collateral and/or be limited in amount to the
value of the lender's interest in the collateral as of the date of the
bankruptcy. The loan term may be extended, the interest rate may be adjusted to
market rates and the priority of the loan may be subordinated to bankruptcy
court-approved financing. The bankruptcy court can, in effect, invalidate due-
on-sale clauses through confirmed Chapter 11 plans of reorganization.
 
     The Bankruptcy Code provides priority to certain tax liens over the
lender's security. This may delay or interfere with the enforcement of rights in
respect of a defaulted mortgage loan. In addition, substantive requirements are
imposed upon lenders in connection with the origination and the servicing of
mortgage loans by numerous federal and some state consumer protection laws. The
laws include the federal Truth-in-Lending Act, Real Estate Settlement Procedures
Act, Equal Credit Opportunity Act, Fair Credit Billing Act, Fair Credit
Reporting Act and related statutes and regulations. These federal laws impose
specific statutory liabilities upon lenders who originate loans and who fail to
comply with the provisions of the law. In some cases, this liability may affect
assignees of the loans.
 
DUE-ON-SALE CLAUSES IN MORTGAGE LOANS
 
     Due-on-sale clauses permit the lender to accelerate the maturity of the
loan if the borrower sells or transfers, whether voluntarily or involuntarily,
all or part of the real property securing the loan without the lender's prior
written consent. The enforceability of these clauses has been the subject of
legislation or litigation in many states, and in some cases, typically involving
single family residential mortgage transactions, their enforceability has been
limited or denied. In any event, the Garn-St. Germain Depository Institutions
Act of 1982 (the "Garn-St. Germain Act") preempts state constitutional,
statutory and case law that prohibits the enforcement of due-on-sale clauses and
permits lenders to enforce these clauses in accordance with their terms, subject
to certain exceptions. As a result, due-on-sale clauses have become generally
enforceable except in those states whose legislatures exercised their authority
to regulate the enforceability of such clauses with respect to mortgage loans
that were (i) originated or assumed during the "window period" under the
Garn-St. Germain Act, which ended in all cases not later than October 15, 1982,
and (ii) originated by lenders other than national banks, federal savings
institutions and federal credit unions. FHLMC has taken the position in its
published mortgage servicing standards that, out of a total of eleven "window
period states," five states (Arizona, Michigan, Minnesota, New Mexico and Utah)
have enacted statutes extending, on various terms and for varying periods, the
prohibition on enforcement of due-on-sale clauses with respect to certain
categories of window period loans. Also, the Garn-St. Germain Act does
"encourage" lenders to permit assumption of loans at the original rate of
interest or at some other rate less than the average of the original rate and
the market rate.
 
     In addition, under federal bankruptcy law, due-on-sale clauses may not be
enforceable in bankruptcy proceedings and may, under certain circumstances, be
eliminated in any modified mortgage resulting from such bankruptcy proceeding.
 
                                       51
<PAGE>   148
 
ENFORCEABILITY OF PREPAYMENT AND LATE PAYMENT FEES
 
     Forms of notes, mortgages and deeds of trust used by lenders may contain
provisions obligating the borrower to pay a late charge if payments are not
timely made, and in some circumstances may provide for prepayment fees or
penalties if the obligation is paid prior to maturity. In certain states, there
are or may be specific limitations, upon the late charges a lender may collect
from a borrower for delinquent payments. Certain states also limit the amounts
that a lender may collect from a borrower as an additional charge if the loan is
prepaid. Late charges and prepayment fees are typically retained by servicers as
additional servicing compensation.
 
EQUITABLE LIMITATIONS ON REMEDIES
 
     In connection with lenders' attempts to realize upon their security, courts
have invoked general equitable principles. The equitable principles are
generally designed to relieve the borrower from the legal effect of his defaults
under the loan documents. Examples of judicial remedies that have been fashioned
include judicial requirements that the lender undertake affirmative and
expensive actions to determine the causes of the borrower's default and the
likelihood that the borrower will be able to reinstate the loan. In some cases,
courts have substituted their judgment for the lender's judgment and have
required that lenders reinstate loans or recast payment schedules in order to
accommodate borrowers who are suffering from temporary financial disability. In
other cases, courts have limited the right of a lender to realize upon his
security if the default under the security agreement is not monetary, such as
the borrower's failure to adequately maintain the property or the borrower's
execution of secondary financing affecting the property. Finally, some courts
have been faced with the issue of whether or not federal or state constitutional
provisions reflecting due process concerns for adequate notice require that
borrowers under security agreements receive notices in addition to the
statutorily-prescribed minimums. For the most part, these cases have upheld the
notice provisions as being reasonable or have found that, in cases involving the
sale by a trustee under a deed of trust or by a mortgagee under a mortgage
having a power of sale, there is insufficient state action to afford
constitutional protections to the borrower.
 
     Most conventional single-family mortgage loans may be prepaid in full or in
part without penalty. The regulations of the Office of Thrift Supervision (the
"OTS") prohibit the imposition of a prepayment penalty or equivalent fee for or
in connection with the acceleration of a loan by exercise of a due-on-sale
clause. A mortgagee to whom a prepayment in full has been tendered may be
compelled to give either a release of the mortgage or an instrument assigning
the existing mortgage. The absence of a restraint on prepayment, particularly
with respect to mortgage loans having higher mortgage rates, may increase the
likelihood of refinancing or other early retirements of such mortgage loans.
 
APPLICABILITY OF USURY LAWS
 
     Title V of the Depository Institutions Deregulation and Monetary Control
Act of 1980, enacted in March 1980 ("Title V"), provides that state usury
limitations shall not apply to certain types of residential first mortgage loans
originated by certain lenders after March 31, 1980. Similar federal statutes
were in effect with respect to mortgage loans made during the first three months
of 1980. The OTS, as successor to the Federal Home Loan Bank Board, is
authorized to issue rules and regulations and to publish interpretations
governing implementation of Title V. Title V authorizes any state to reimpose
interest rate limits by adopting, before April 1, 1983, a state law, or by
certifying that the voters of such state have voted in favor of any provision,
constitutional or otherwise, which expressly rejects an application of the
federal law. Fifteen states adopted such a law prior to the April 1, 1983
deadline. In addition, even where Title V is not so rejected, any state is
authorized by the law to adopt a provision limiting discount points or other
charges on mortgage loans covered by Title V.
 
THE HOME IMPROVEMENT CONTRACTS
 
  General
 
     The Home Improvement Contracts, other than those Home Improvement Contracts
that are unsecured or secured by mortgages on real estate (such Home Improvement
Contracts are hereinafter referred to in this section as "contracts") generally
are "chattel paper" or constitute "purchase money security interests," each
 
                                       52
<PAGE>   149
 
as defined in the Uniform Commercial Code in effect in the applicable
jurisdiction (the "UCC"). Pursuant to the UCC, the sale of chattel paper is
treated in a manner similar to perfection of a security interest in chattel
paper. Under the related Agreement, the Depositor will transfer physical
possession of the contracts to the Trustee or a designated custodian or may
retain possession of the contracts as custodian for the Trustee. In addition,
the Depositor will make an appropriate filing of a UCC-1 financing statement in
the appropriate states to give notice of the Trustee's ownership of the
contracts. Unless otherwise specified in the related Prospectus Supplement, the
contracts will not be stamped or otherwise marked to reflect their assignment
from the Depositor to the Trustee. Therefore, if through negligence, fraud or
otherwise, a subsequent purchaser were able to take physical possession of the
contracts without notice of such assignment, the Trustee's interest in the
contracts could be defeated.
 
  Security Interests in Home Improvements
 
     The contracts that are secured by the Home Improvements financed thereby
grant to the originator of such contracts a purchase money security interest in
such Home Improvements to secure all or part of the purchase price of such Home
Improvements and related services. A financing statement generally is not
required to be filed to perfect a purchase money security interest in consumer
goods. Such purchase money security interests are assignable. In general, a
purchase money security interest grants to the holder a security interest that
has priority over a conflicting security interest in the same collateral and the
proceeds of such collateral. However, to the extent that the collateral subject
to a purchase money security interest becomes a fixture, in order for the
related purchase money security interest to take priority over a conflicting
interest in the fixture, the holder's interest in such Home Improvement must
generally be perfected by a timely fixture filing. In general, under the UCC, a
security interest does not exist under the UCC in ordinary building material
incorporated into an improvement on land. Home Improvement Contracts that
finance lumber, bricks, other types of ordinary building material or other goods
that are deemed to lose such characterization, upon incorporation of such
materials into the related property, will not be secured by a purchase money
security interest in the Home Improvement being financed.
 
  Enforcement of Security Interest in Home Improvements
 
     So long as the Home Improvement has not become subject to the real estate
law, a creditor can repossess a Home Improvement securing a contract 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 contract must give the debtor a number of days' notice, which varies
from 10 to 30 days depending on the state, 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
debtor and commercial reasonableness in effecting such a sale. The law in most
states also requires that the debtor be given notice of any sale prior to resale
of the unit that the debtor may redeem it at or before such resale.
 
     Under the laws applicable in most states, a creditor is entitled to obtain
a deficiency judgement from a debtor for any deficiency on repossession and
resale of the property securing the debtor's loan. However, some states impose
prohibitions or limitations on deficiency judgements, and in many cases the
defaulting borrower would have no assets with which to pay a judgement.
 
     Certain other statutory provisions, including federal and state bankruptcy
and insolvency laws and general equitable principles, may limit or delay the
ability of a lender to repossess and resell collateral or enforce a deficiency
judgement.
 
  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 that is the seller of goods that gave rise to the transaction (and
certain related lenders and assignees) to transfer such contract free of notice
of claims by the debtor thereunder. The effect of this rule is to subject the
assignee of such a contract to all claims and defenses the debtor could assert
against the seller of goods. Liability under this rule is limited to amounts
paid under a contract; however, the obligor also may be able to assert the rule
to set off remaining amounts due as a defense
 
                                       53
<PAGE>   150
 
against a claim brought by the Trustee against such obligor. Numerous other
federal and state consumer protection laws impose requirements applicable to the
origination and lending pursuant to the contracts, including the Truth in
Lending Act, the Federal Trade Commission Act, the Fair Credit Billing Act, the
Fair Credit Reporting Act, the Equal Credit Opportunity Act, the Fair Debt
Collection Practices Act and the Uniform Consumer Credit Code. In the case of
some of these laws, the failure to comply with their provisions may affect the
enforceability of the related contract.
 
  Applicability of Usury Laws
 
     Title V provides that, subject to the following conditions, state usury
limitations shall not apply to any contract that is secured by a first lien on
certain kinds of consumer goods. The contracts would be covered if they satisfy
certain conditions, among other things, governing the terms of any prepayments,
late charges and deferral fees and requiring a 30-day notice period prior to
instituting any action leading to repossession of the related unit.
 
     Title V authorized any state to reimpose limitations on interest rates and
finance charges by adopting before April 1, 1983 a law or constitutional
provision that expressly rejects 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.
 
INSTALLMENT SALES CONTRACTS
 
     The Loans may also consist of installment sales contracts. Under an
installment sales contract (each, an "Installment Sales Contract") the seller
(hereinafter referred to in this section as the "lender") retains legal title to
the property and enters into an agreement with the purchaser (hereinafter
referred to in this section as the "borrower") for the payment of the purchase
price, plus interest, over the term of such contract. Only after full
performance by the borrower of the contract is the lender obligated to convey
title to the property to the purchaser. As with mortgage or deed of trust
financing, during the effective period of the Installment Sales Contract, the
borrower is generally responsible for maintaining the property in good condition
and for paying real estate taxes, assessments and hazard Insurance Policy
premiums associated with the property.
 
     The method of enforcing the rights of the lender under an Installment Sales
Contract varies on a state-by-state basis depending upon the extent to which
state courts are willing, or able pursuant to state statute, to enforce the
contract strictly according to the terms. The terms of Installment Sales
Contracts generally provide that upon a default by the borrower, the borrower
loses his or her right to occupy the property, the entire indebtedness is
accelerated, and the buyer's equitable interest in the property is forfeited.
The lender in such a situation does not have to foreclose in order to obtain
title to the property, although in some cases a quiet title action is in order
if the borrower has filed the Installment Sales Contract in local land records
and an ejectment action may be necessary to recover possession. In a few states,
particularly in cases of borrower default during the early years of an
Installment Sales Contract, the courts will permit ejectment of the buyer and a
forfeiture of his or her interest in the property. However, most state
legislatures have enacted provisions by analogy to mortgage law protecting
borrowers under Installment Sales Contracts from the harsh consequences of
forfeiture. Under such statutes, a judicial or nonjudicial foreclosure may be
required, the lender may be required to give notice of default and the borrower
may be granted some grace period during which the Installment Sales Contract may
be reinstated upon full payment of the default amount and the borrower may have
a post-foreclosure statutory redemption right. In other states, courts in equity
may permit a borrower with significant investment in the property under an
Installment Sales Contract for the sale of real estate to share in the proceeds
of sale of the property after the indebtedness is repaid or may otherwise refuse
to enforce the forfeiture clause. Nevertheless, generally speaking, the lender's
procedures for obtaining possession and clear title under an Installment Sales
Contract in a given state are simpler and less time-consuming and costly than
are the procedures for foreclosing and obtaining clear title to a property
subject to one or more liens.

SOLDIERS' AND SAILORS' CIVIL RELIEF ACT OF 1940
 
     Under the Soldiers' and Sailors' Civil Relief Act of 1940, members of all
branches of the military on active duty, including draftees and reservists in
military service, (i) are entitled to have interest rates reduced and capped at
6% per annum, on obligations (including Loans) incurred prior to the
commencement of military service for the duration of military service, (ii) may
be entitled to a stay of proceedings on any kind of foreclosure or repossession
action in the case of defaults on such obligations entered into prior to
military service for the duration of military service and (iii) may have the
maturity of such obligations incurred prior to military service extended, the
payments lowered and the payment schedule readjusted for a period of time after
the completion of military service. However, the benefits of (i), (ii), or (iii)
above are subject to challenge by creditors and if, in the opinion of the court,
the ability of a person to comply with such obligations is not materially
impaired by military service, the court may apply equitable principles
accordingly. If a borrower's obligation to repay amounts otherwise due on a Loan
included in a Trust Fund for a Series is relieved pursuant to the Soldiers' and
Sailors' Civil Relief Act of 1940, none of the Trust Fund, the Servicer, the
Depositor nor any Trustee will be required to advance such amounts, and any loss
in respect thereof may reduce the amounts available to be paid to the Holders of
the Securities of such Series. Unless otherwise specified in the related
Prospectus Supplement, any shortfalls in interest collections on Loans or
Underlying Loans relating to the Private Securities, as applicable, included in
a Trust Fund for a Series resulting from application of the Soldiers' and
Sailors' Civil Relief Act of 1940 will be allocated to each Class of Securities
of such Series that is entitled to receive interest in respect of such Loans or
Underlying Loans in proportion to the interest that each such Class of
Securities would have otherwise been entitled to receive in respect of such
Loans or Underlying Loans had such interest shortfall not occurred.
 
                                 THE DEPOSITOR
 
     The Depositor was incorporated in the State of Delaware in June 1995, and
is a wholly-owned subsidiary of The Bear Stearns Companies Inc. The Depositor's
principal executive offices are located at 245 Park Avenue, New York, New York
10167. Its telephone number is (212) 272-4095.
 
     The Depositor will not engage in any activities other than to authorize,
issue, sell, deliver, purchase and invest in (and enter into agreements in
connection with), and/or to engage in the establishment of one or more trusts,
which will issue and sell, bonds, notes, debt or equity securities, obligations
and other securities and instruments ("Depositor Securities") collateralized or
otherwise secured or backed by, or otherwise representing an interest in, among
other things, receivables or pass-through certificates, or participations or
certificates of participation or beneficial ownership in one or more pools of
receivables, and the proceeds of the foregoing, that arise in connection with
loans secured by certain first or junior mortgages on real estate or
manufactured housing and any and all other commercial transactions and
commercial, sovereign, student or consumer loans or indebtedness and, in
connection therewith or otherwise, purchasing, acquiring, owning, holding,
transferring, conveying, servicing, selling, pledging, assigning, financing and
otherwise dealing with such receivables, pass-through certificates, or
participations or certificates of participation or beneficial ownership. Article
Third of the Depositor's Certificate of Incorporation limits the Depositor's
activities to the above activities and certain related activities, such as
credit enhancement with respect to such Depositor Securities, and to any
activities incidental to and necessary or convenient for the accomplishment of
such purposes.
 
                                USE OF PROCEEDS
 
     The Depositor will apply all or substantially all of the net proceeds from
the sale of each Series of Securities for one or more of the following purposes:
(i) to purchase the related Primary Assets, (ii) to repay indebtedness incurred
to obtain funds to acquire such Primary Assets, (iii) to establish any Reserve
Funds described in the related Prospectus Supplement and (iv) to pay costs of
structuring and issuing such Securities, including the costs of obtaining
Enhancement, if any. If so specified in the related Prospectus Supplement, the
purchase of the Primary Assets for a Series may be effected by an exchange of
Securities with the Seller of such Primary Assets.

                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
GENERAL
 
     The following is a summary of certain anticipated material federal income
tax consequences of the purchase, ownership, and disposition of the Securities
and is based on the opinion of Brown & Wood LLP, special counsel to the
Depositor (in such capacity, "Tax Counsel"). The summary is based upon the
provisions of the Code, the regulations promulgated thereunder, including, where
applicable, proposed regulations, and the judicial and administrative rulings
and decisions now in effect, all of which are subject to change or possible
differing interpretations. The statutory provisions, regulations, and
interpretations on which this interpretation is based are subject to change, and
such a change could apply retroactively.
 
     The summary does not purport to deal with all aspects of federal income
taxation that may affect particular investors in light of their individual
circumstances. This summary focuses primarily upon investors who will hold
Securities as "capital assets" (generally, property held for investment) within
the meaning of Section 1221 of the Code. Prospective investors may wish to
consult their own tax advisers concerning the federal, state, local and any
other tax consequences as relates specifically to such investors in connection
with the purchase, ownership and disposition of the Securities.
 
     The federal income tax consequences to Holders will vary depending on
whether (i) the Securities of a Series are classified as indebtedness; (ii) an
election is made to treat the Trust Fund relating to a particular Series of
Securities as a real estate mortgage investment conduit (a "REMIC") under the
Internal Revenue Code of 1986, as amended (the "Code"); (iii) the Securities
represent an ownership interest in some or all of the assets included in the
Trust Fund for a Series; or (iv) an election is made to treat the Trust Fund
relating to a particular Series of Certificates as a partnership; or (v) an
election is made to treat the Trust Fund relating to a particular Series of
Securities as a Financial Asset Securitization Investment Trust ("FASIT") under
the Code. The Prospectus Supplement for each Series of Securities will specify
how the Securities will be treated for federal income tax purposes and will
discuss whether a REMIC election, if any, will be made with respect to such
Series.
 
     As used herein, the term "U.S. Person" means 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, any state thereof or the District of
Columbia (other than a partnership that is not treated as a United States person
under any applicable Treasury regulations), an estate whose income is subject to
U.S. federal income tax regardless of its source of income, or a trust if a
court within the United States is able to exercise primary supervision of the
trust and one or more United States persons have the authority to control all
substantial decisions of the trust. Notwithstanding the preceding sentence, to
the extent provided in regulations, certain trusts in existence on August 20,
1996 and treated as United States persons prior to such date that elect to
continue to be treated as United States persons shall be considered U.S. Persons
as well.
 
TAXATION OF DEBT SECURITIES
 
     Status as Real Property Loans.  Except to the extent otherwise provided in
the related Prospectus Supplement, if the Securities are regular interests in a
REMIC ("Regular Interest Securities") or represent interests in a grantor trust,
Tax Counsel is of the opinion that: (i) Securities held by a domestic building
and loan association will constitute "loans... secured by an interest in real
property" within the meaning of Code section 7701(a)(19)(C)(v); and (ii)
Securities held by a real estate investment trust will constitute "real estate
assets" within the meaning of Code section 856(c)(4)(A) and interest on
Securities will be considered "interest on obligations secured by mortgages on
real property or on interests in real property" within the meaning of Code
section 856(c)(3)(B).
 
     Interest and Acquisition Discount.  In the opinion of Tax Counsel, Regular
Interest Securities are generally taxable to Holders in the same manner as
evidences of indebtedness issued by the REMIC. Stated interest on the Regular
Interest Securities will be taxable as ordinary income and taken into account
using the accrual method of accounting, regardless of the Holder's normal
accounting method. Interest (other than original issue discount) on Securities
(other than Regular Interest Securities) that are characterized as indebtedness
for federal income tax purposes will be includible in income by Holders thereof
in accordance
 
                                       56
<PAGE>   153
 
with their usual methods of accounting. Securities characterized as debt for
federal income tax purposes and Regular Interest Securities will be referred to
hereinafter collectively as "Debt Securities."
 
     Tax Counsel is of the opinion that Debt Securities that are Compound
Interest Securities will, and certain of the other Debt Securities issued at a
discount may, be issued with "original issue discount" ("OID"). The following
discussion is based in part on the rules governing OID, which are set forth in
Sections 1271-1275 of the Code and the Treasury regulations issued thereunder on
February 2, 1994 and amended on June 11, 1996 (the "OID Regulations"). A Holder
should be aware, however, that the OID Regulations do not adequately address
certain issues relevant to prepayable securities, such as the Debt Securities.
 
     In general, OID, if any, will equal the difference between the stated
redemption price at maturity of a Debt Security and its issue price. In the
opinion of Tax Counsel, a Holder of a Debt Security must include such OID in
gross income as ordinary interest income as it accrues under a method taking
into account an economic accrual of the discount. In general, OID must be
included in income in advance of the receipt of the cash representing that
income. The amount of OID on a Debt Security will be considered to be zero if it
is less than a de minimis amount determined under the Code.
 
     The issue price of a Debt Security is the first price at which a
substantial amount of Debt Securities of that Class are sold to the public
(excluding bond houses, brokers, underwriters or wholesalers). If less than a
substantial amount of a particular Class of Debt Securities is sold for cash on
or prior to the Closing Date, the issue price for such Class will be treated as
the fair market value of such Class on the Closing Date. The issue price of a
Debt Security also includes the amount paid by an initial Debt Security Holder
for accrued interest that relates to a period prior to the issue date of the
Debt Security. The stated redemption price at maturity of a Debt Security
includes the original principal amount of the Debt Security, but generally will
not include distributions of interest if such distributions constitute
"qualified stated interest."
 
     Under the OID Regulations, qualified stated interest generally means
interest payable at a single fixed rate or qualified variable rate (as described
below); provided, that such interest payments are unconditionally payable at
intervals of one year or less during the entire term of the Debt Security. The
OID Regulations state that interest payments are unconditionally payable only if
a late payment or nonpayment is expected to be penalized or reasonable remedies
exist to compel payment. Certain Debt Securities may provide for default
remedies in the event of late payment or nonpayment of interest. In the opinion
of Tax Counsel, the interest on such Debt Securities will be unconditionally
payable and constitute qualified stated interest, not OID. However, absent
clarification of the OID Regulations, where Debt Securities do not provide for
default remedies, the interest payments will be included in the Debt Security's
stated redemption price at maturity and taxed as OID. Interest is payable at a
single fixed rate only if the rate appropriately takes into account the length
of the interval between payments. Distributions of interest on Debt Securities
with respect to which deferred interest will accrue, will not constitute
qualified stated interest payments, in which case the stated redemption price at
maturity of such Debt Securities includes all distributions of interest as well
as principal thereon. Where the interval between the issue date and the first
Distribution Date on a Debt Security is either longer or shorter than the
interval between subsequent Distribution Dates, all or part of the interest
foregone, in the case of the longer interval, and all of the additional
interest, in the case of the shorter interval, will be included in the stated
redemption price at maturity and tested under the de minimis rule described
below. In the case of a Debt Security with a long first period that has non-de
minimis OID, all stated interest in excess of interest payable at the effective
interest rate for the long first period will be included in the stated
redemption price at maturity and the Debt Security will generally have OID.
Holders of Debt Securities should consult their own tax advisors to determine
the issue price and stated redemption price at maturity of a Debt Security.
 
     Under the de minimis rule, OID on a Debt Security will be considered to be
zero if such OID is less than 0.25% of the stated redemption price at maturity
of the Debt Security multiplied by the weighted average maturity of the Debt
Security. For this purpose, the weighted average maturity of the Debt Security
is computed as the sum of the amounts determined by multiplying the number of
full years (i.e., rounding down partial years) from the issue date until each
distribution in reduction of stated redemption price at maturity is scheduled to
be made by a fraction, the numerator of which is the amount of each distribution
included in the
 
                                       57
<PAGE>   154
 
stated redemption price at maturity of the Debt Security and the denominator of
which is the stated redemption price at maturity of the Debt Security. Holders
generally must report de minimis OID pro rata as principal payments are
received, and such income will be capital gain if the Debt Security is held as a
capital asset. However, accrual method Holders may elect to accrue all de
minimis OID as well as market discount under a constant interest method.
 
     Debt Securities may provide for interest based on a qualified variable
rate. Under the OID Regulations, interest is treated as payable at a qualified
variable rate and not as contingent interest if, generally, (i) such interest is
unconditionally payable at least annually, (ii) the issue price of the debt
instrument does not exceed the total noncontingent principal payments and (iii)
interest is based on a "qualified floating rate," an "objective rate," or a
combination of "qualified floating rates" that do not operate in a manner that
significantly accelerates or defers interest payments on such Debt Security. In
the case of Compound Interest Securities, certain Interest Weighted Securities,
and certain of the other Debt Securities, none of the payments under the
instrument will be considered qualified stated interest, and thus the aggregate
amount of all payments will be included in the stated redemption price.
 
     The Internal Revenue Service (the "IRS") recently issued final regulations
(the "Contingent Payment Regulations") governing the calculation of OID on
instruments having contingent interest payments. The Contingent Payment
Regulations, represent the only guidance regarding the views of the IRS with
respect to contingent interest instruments and specifically do not apply for
purposes of calculating OID on debt instruments subject to Code Section
1272(a)(6), such as the Debt Security. Additionally, the OID Regulations do not
contain provisions specifically interpreting Code Section 1272(a)(6). Until the
Treasury issues guidance to the contrary, the applicable Trustee intends to base
its computation on Code Section 1272(a)(6) and the OID Regulations as described
in this Prospectus. However, because no regulatory guidance currently exists
under Code Section 1272(a)(6), there can be no assurance that such methodology
represents the correct manner of calculating OID.
 
     The Holder of a Debt Security issued with OID must include in gross income,
for all days during its taxable year on which it holds such Debt Security, the
sum of the "daily portions" of such original issue discount. The amount of OID
includible in income by a Holder will be computed by allocating to each day
during a taxable year a pro rata portion of the original issue discount that
accrued during the relevant accrual period. In the case of a Debt Security that
is not a Regular Interest Security and the principal payments on which are not
subject to acceleration resulting from prepayments on the Loans, the amount of
OID includible in income of a Holder for an accrual period (generally the period
over which interest accrues on the debt instrument) will equal the product of
the yield to maturity of the Debt Security and the adjusted issue price of the
Debt Security, reduced by any payments of qualified stated interest. The
adjusted issue price is the sum of its issue price plus prior accruals or OID,
reduced by the total payments made with respect to such Debt Security in all
prior periods, other than qualified stated interest payments.
 
     The amount of OID to be included in income by a Holder of a debt
instrument, such as certain Classes of the Debt Securities, that is subject to
acceleration due to prepayments on other debt obligations securing such
instruments (a "Pay-Through Security"), is computed by taking into account the
anticipated rate of prepayments assumed in pricing the debt instrument (the
"Prepayment Assumption"). The amount of OID that will accrue during an accrual
period on a Pay-Through Security is the excess (if any) of the sum of (a) the
present value of all payments remaining to be made on the Pay-Through Security
as of the close of the accrual period and (b) the payments during the accrual
period of amounts included in the stated redemption price of the Pay-Through
Security, over the adjusted issue price of the Pay-Through Security at the
beginning of the accrual period. The present value of the remaining payments is
to be determined on the basis of three factors: (i) the original yield to
maturity of the Pay-Through Security (determined on the basis of compounding at
the end of each accrual period and properly adjusted for the length of the
accrual period), (ii) events that have occurred before the end of the accrual
period and (iii) the assumption that the remaining payments will be made in
accordance with the original Prepayment Assumption. The effect of this method is
to increase the portions of OID required to be included in income by a Holder to
take into account prepayments with respect to the Loans at a rate that exceeds
the Prepayment Assumption, and to decrease (but not below zero for any period)
the portions of OID required to be included in income by a Holder of a
 
                                       58
<PAGE>   155
 
Pay-Through Security to take into account prepayments with respect to the Loans
at a rate that is slower than the Prepayment Assumption. Although OID will be
reported to Holders of Pay-Through Securities based on the Prepayment
Assumption, no representation is made to Holders that Loans will be prepaid at
that rate or at any other rate.
 
     The Depositor may adjust the accrual of OID on a Class of Regular Interest
Securities (or other regular interests in a REMIC) in a manner that it believes
to be appropriate, to take account of realized losses on the Loans, although the
OID Regulations do not provide for such adjustments. If the IRS were to require
that OID be accrued without such adjustments, the rate of accrual of OID for a
Class of Regular Interest Securities could increase.
 
     Certain Classes of Regular Interest Securities may represent more than one
Class of REMIC regular interests. Unless otherwise provided in the related
Prospectus Supplement, the applicable Trustee intends, based on the OID
Regulations, to calculate OID on such Securities as if, solely for the purposes
of computing OID, the separate regular interests were a single debt instrument.
 
     A subsequent Holder of a Debt Security will also be required to include OID
in gross income, but such a Holder who purchases such Debt Security for an
amount that exceeds its adjusted issue price will be entitled (as will an
initial Holder who pays more than a Debt Security's issue price) to offset such
OID by comparable economic accruals of portions of such excess.
 
     Effects of Defaults and Delinquencies.  In the opinion of Tax Counsel,
Holders will be required to report income with respect to the related Securities
under an accrual method without giving effect to delays and reductions in
distributions attributable to a default or delinquency on the Loans, except
possibly to the extent that it can be established that such amounts are
uncollectible. As a result, the amount of income (including OID) reported by a
Holder of such a Security 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 Securities is reduced
as a result of a Loan default. However, the timing and character of such losses
or reductions in income are uncertain and, accordingly, Holders of Securities
should consult their own tax advisors on this point.
 
     Interest Weighted Securities.  It is not clear how income should be accrued
with respect to Regular Interest Securities or Stripped Securities (as defined
under " -- Tax Status as a Grantor Trust; General" herein) the payments on which
consist solely or primarily of a specified portion of the interest payments on
qualified mortgages held by the REMIC or on Loans underlying Pass-Through
Securities ("Interest Weighted Securities"). The Trustee intends to take the
position that all of the income derived from an Interest Weighted Security
should be treated as OID and that the amount and rate of accrual of such OID
should be calculated by treating the Interest Weighted Security as a Compound
Interest Security. However, in the case of Interest Weighted Securities that are
entitled to some payments of principal and that are Regular Interest Securities
the Internal Revenue Service could assert that income derived from an Interest
Weighted Security should be calculated as if the Security were a security
purchased at a premium equal to the excess of the price paid by such Holder for
such Security over its stated principal amount, if any. Under this approach, a
Holder would be entitled to amortize such premium only if it has in effect an
election under Section 171 of the Code with respect to all taxable debt
instruments held by such Holder, as described below. Alternatively, the IRS
could assert that an Interest Weighted Security should be taxable under the
rules governing bonds issued with contingent payments. Such treatment may be
more likely in the case of Interest Weighted Securities that are Stripped
Securities as described below. See " -- Tax Status as a Grantor
Trust -- Discount or Premium on Pass-Through Securities."
 
     Variable Rate Debt Securities.  In the opinion of Tax Counsel, in the case
of Debt Securities bearing interest at a rate that varies directly, according to
a fixed formula, with an objective index, it appears that (i) the yield to
maturity of such Debt Securities and (ii) in the case of Pay-Through Securities,
the present value of all payments remaining to be made on such Debt Securities,
should be calculated as if the interest index remained at its value as of the
issue date of such Securities. Because the proper method of adjusting accruals
of OID on a variable rate Debt Security is uncertain, Holders of variable rate
Debt Securities should
 
                                       59
<PAGE>   156
 
consult their own tax advisers regarding the appropriate treatment of such
Securities for federal income tax purposes.
 
     Market Discount.  In the opinion of Tax Counsel, a purchaser of a Security
may be subject to the market discount rules of Sections 1276-1278 of the Code. A
Holder that acquires a Debt Security with more than a prescribed de minimis
amount of "market discount" (generally, the excess of the principal amount of
the Debt Security over the purchaser's purchase price) will be required to
include accrued market discount in income as ordinary income in each month, but
limited to an amount not exceeding the principal payments on the Debt Security
received in that month and, if the Securities are sold, the gain realized. Such
market discount would accrue in a manner to be provided in Treasury regulations
but, until such regulations are issued, such market discount would in general
accrue either (i) on the basis of a constant yield (in the case of a Pay-Through
Security, taking into account a prepayment assumption) or (ii) in the ratio of
(a) in the case of Securities (or in the case of a Pass-Through Security, as set
forth below, the Loans underlying such Security) not originally issued with
original issue discount, stated interest payable in the relevant period to total
stated interest remaining to be paid at the beginning of the period or (b) in
the case of Securities (or, in the case of a Pass-Through Security, as described
below, the Loans underlying such Security) originally issued at a discount, OID
in the relevant period to total OID remaining to be paid.
 
     Section 1277 of the Code provides that, regardless of the origination date
of the Debt Security (or, in the case of a Pass-Through Security, the Loans),
the excess of interest paid or accrued to purchase or carry a Security (or, in
the case of a Pass-Through Security, as described below, the underlying Loans)
with market discount over interest received on such Security is allowed as a
current deduction only to the extent such excess is greater than the market
discount that accrued during the taxable year in which such interest expense was
incurred. In general, the deferred portion of any interest expense will be
deductible when such market discount is included in income, including upon the
sale, disposition, or repayment of the Security (or in the case of a
Pass-Through Security, an underlying Loan). A Holder may elect to include market
discount in income currently as it accrues, on all market discount obligations
acquired by such Holder during the taxable year such election is made and
thereafter, in which case the interest deferral rule will not apply.
 
     Premium.  In the opinion of Tax Counsel, a Holder who purchases a Debt
Security (other than an Interest Weighted Security to the extent described
above) at a cost greater than its stated redemption price at maturity, generally
will be considered to have purchased the Security at a premium, which it may
elect to amortize as an offset to interest income on such Security (and not as a
separate deduction item) on a constant yield method. Although no regulations
addressing the computation of premium accrual on securities similar to the
Securities have been issued, the legislative history of the 1986 Act indicates
that premium is to be accrued in the same manner as market discount.
Accordingly, it appears that the accrual of premium on a Class of Pay-Through
Securities will be calculated using the prepayment assumption used in pricing
such Class. If a Holder makes an election to amortize premium on a Debt
Security, such election will apply to all taxable debt instruments (including
all REMIC regular interests and all pass-through certificates representing
ownership interests in a trust holding debt obligations) held by the Holder at
the beginning of the taxable year in which the election is made, and to all
taxable debt instruments acquired thereafter by such Holder, and will be
irrevocable without the consent of the IRS. Purchasers who pay a premium for the
Securities should consult their tax advisers regarding the election to amortize
premium and the method to be employed.
 
     Election to Treat All Interest as Original Issue Discount. The OID
Regulations permit a Holder of a Debt Security to elect to accrue all interest,
discount (including de minimis market or original issue discount) and premium in
income as interest, based on a constant yield method for Debt Securities
acquired on or after April 4, 1994. If such an election were to be made with
respect to a Debt Security with market discount, the Holder of the Debt Security
would be deemed to have made an election to include in income currently market
discount with respect to all other debt instruments having market discount that
such Holder of the Debt Security acquires during the year of the election or
thereafter. Similarly, a Holder of a Debt Security that makes this election for
a Debt Security that is acquired at a premium will be deemed to have made an
election to amortize bond premium with respect to all debt instruments having
amortizable bond premium that such Holder owns or acquires. The election to
accrue interest, discount and premium on a constant yield method with respect to
a Debt Security is irrevocable.

TAXATION OF THE REMIC AND ITS HOLDERS
 
     General.  In the opinion of Tax Counsel, if a REMIC election is made with
respect to a Series of Securities, then the arrangement by which the Securities
of that Series are issued will be treated as a REMIC as long as all of the
provisions of the applicable Agreement are complied with and the statutory and
regulatory requirements are satisfied. Securities will be designated as "Regular
Interests" or "Residual Interests" in a REMIC, as specified in the related
Prospectus Supplement.
 
     Except to the extent specified otherwise in a Prospectus Supplement, if a
REMIC election is made with respect to a Series of Securities, in the opinion of
Tax Counsel (i) Securities held by a domestic building and loan association will
constitute "a regular or a residual interest in a REMIC" within the meaning of
Code Section 7701(a)(19)(C)(xi) (assuming that at least 95% of the REMIC's
assets consist of cash, government securities, "loans secured by an interest in
real property," and other types of assets described in Code Section
7701(a)(19)(C)); and (ii) Securities held by a real estate investment trust will
constitute "real estate assets" within the meaning of Code Section 856(c)(4)(A),
and income with respect to the Securities will be considered "interest on
obligations secured by mortgages on real property or on interests in real
property" within the meaning of Code Section 856(c)(3)(B) (assuming, for both
purposes, that at least 95% of the REMIC's assets are qualifying assets). If
less than 95% of the REMIC's assets consist of assets described in (i) or (ii)
above, then a Security will qualify for the tax treatment described in (i) or
(ii) in the proportion that such REMIC assets are qualifying assets.
 
REMIC EXPENSES; SINGLE CLASS REMICS
 
     As a general rule, in the opinion of Tax Counsel, all of the expenses of a
REMIC will be taken into account by Holders of the Residual Interest Securities.
In the case of a "single class REMIC," however, the expenses will be allocated,
under Treasury regulations, among the Holders of the Regular Interest Securities
and the Holders of the Residual Interest Securities on a daily basis in
proportion to the relative amounts of income accruing to each Holder on that
day. In the case of a Holder of a Regular Interest Security who is an individual
or a "pass-through interest holder" (including certain pass-through entities but
not including real estate investment trusts), such expenses will be deductible
only to the extent that such expenses, plus other "miscellaneous itemized
deductions" of the Holder, exceed 2% of such Holder's adjusted gross income. In
addition, for taxable years beginning after December 31, 1990, the amount of
itemized deductions otherwise allowable for the taxable year for an individual
whose adjusted gross income exceeds the applicable amount (which amount will be
adjusted for inflation for taxable years beginning after 1990) will be reduced
by the lesser of (i) 3% of the excess of adjusted gross income over the
applicable amount, or (ii) 80% of the amount of itemized deductions otherwise
allowable for such taxable year. The reduction or disallowance of this deduction
may have a significant impact on the yield of the Regular Interest Security to
such a Holder. In general terms, a single class REMIC is one that either (i)
would qualify, under existing Treasury regulations, as a grantor trust if it
were not a REMIC (treating all interests as ownership interests, even if they
would be classified as debt for federal income tax purposes) or (ii) is similar
to such a trust and that is structured with the principal purpose of avoiding
the single class REMIC rules. Unless otherwise specified in the related
Prospectus Supplement, the expenses of the REMIC will be allocated to Holders of
the related residual interest securities.
 
TAXATION OF THE REMIC
 
     General.  Although a REMIC is a separate entity for federal income tax
purposes, in the opinion of Tax Counsel, a REMIC is not generally subject to
entity-level tax. Rather, the taxable income or net loss of a REMIC is taken
into account by the Holders of residual interests. As described above, the
regular interests are generally taxable as debt of the REMIC.
 
     Calculation of REMIC Income.  In the opinion of Tax Counsel, the taxable
income or net loss of a REMIC is determined under an accrual method of
accounting and in the same manner as in the case of an individual, with certain
adjustments. In general, the taxable income or net loss will be the difference
between (i) the gross income produced by the REMIC's assets, including stated
interest and any original issue discount or market discount on loans and other
assets, and (ii) deductions, including stated interest and original issue
discount accrued on Regular Interest Securities, amortization of any premium
with respect to
                                       61
<PAGE>   158
 
Loans, and servicing fees and other expenses of the REMIC. A Holder of a
Residual Interest Security that is an individual or a "pass-through interest
holder" (including certain pass-through entities, but not including real estate
investment trusts) will be unable to deduct servicing fees payable on the loans
or other administrative expenses of the REMIC for a given taxable year, to the
extent that such expenses, when aggregated with such Holder's other
miscellaneous itemized deductions for that year, do not exceed two percent of
such Holder's adjusted gross income.
 
     For purposes of computing its taxable income or net loss, the REMIC should
have an initial aggregate tax basis in its assets equal to the aggregate fair
market value of the regular interests and the residual interests on the Startup
Day (generally, the day that the interests are issued). That aggregate basis
will be allocated among the assets of the REMIC in proportion to their
respective fair market values.
 
     The OID provisions of the Code apply to loans of individuals originated on
or after March 2, 1984, and the market discount provisions apply to loans
originated after July 18, 1984. Subject to possible application of the de
minimis rules, the method of accrual by the REMIC of OID income on such loans
will be equivalent to the method under which Holders of Pay-Through Securities
accrue original issue discount (i.e., under the constant yield method taking
into account the Prepayment Assumption). The REMIC will deduct OID on the
Regular Interest Securities in the same manner that the Holders of the Regular
Interest Securities include such discount in income, but without regard to the
de minimis rules. See "Taxation of Debt Securities" above. However, a REMIC that
acquires loans at a market discount must include such market discount in income
currently, as it accrues, on a constant interest basis.
 
     To the extent that the REMIC's basis allocable to loans that it holds
exceeds their principal amounts, the resulting premium, if attributable to
mortgages originated after September 27, 1985, will be amortized over the life
of the loans (taking into account the Prepayment Assumption) on a constant yield
method. Although the law is somewhat unclear regarding recovery of premium
attributable to loans originated on or before such date, it is possible that
such premium may be recovered in proportion to payments of loan principal.
 
     Prohibited Transactions and Contributions Tax.  The REMIC will be subject
to a 100% tax on any net income derived from a "prohibited transaction." For
this purpose, net income will be calculated without taking into account any
losses from prohibited transactions or any deductions attributable to any
prohibited transaction that resulted in a loss. In general, prohibited
transactions include: (i) subject to limited exceptions, the sale or other
disposition of any qualified mortgage transferred to the REMIC; (ii) subject to
a limited exception, the sale or other disposition of a cash flow investment;
(iii) the receipt of any income from assets not permitted to be held by the
REMIC pursuant to the Code; or (iv) the receipt of any fees or other
compensation for services rendered by the REMIC. It is anticipated that a REMIC
will not engage in any prohibited transactions in which it would recognize a
material amount of net income. In addition, subject to a number of exceptions, a
tax is imposed at the rate of 100% on amounts contributed to a REMIC after the
close of the three-month period beginning on the Startup Day. The Holders of
Residual Interest Securities will generally be responsible for the payment of
any such taxes imposed on the REMIC. To the extent not paid by such Holders or
otherwise, however, such taxes will be paid out of the Trust Fund and will be
allocated pro rata to all outstanding Classes of Securities of such REMIC.
 
TAXATION OF HOLDERS OF RESIDUAL INTEREST SECURITIES
 
     In the opinion of Tax Counsel, the Holder of a Certificate representing a
residual interest (a "Residual Interest Security") will take into account the
"daily portion" of the taxable income or net loss of the REMIC for each day
during the taxable year on which such Holder held the Residual Interest
Security. The daily portion is determined by allocating to each day in any
calendar quarter its ratable portion of the taxable income or net loss of the
REMIC for such quarter, and by allocating that amount among the Holders (on such
day) of the Residual Interest Securities in proportion to their respective
holdings on such day.
 
     In the opinion of Tax Counsel, the Holder of a Residual Interest Security
must report its proportionate share of the taxable income of the REMIC whether
or not it receives cash distributions from the REMIC attributable to such income
or loss. The reporting of taxable income without corresponding distributions
could occur, for example, in certain REMIC issues in which the loans held by the
REMIC were issued or acquired at a discount, since mortgage prepayments cause
recognition of discount income, while the corresponding
 
                                       62
<PAGE>   159
 
portion of the prepayment could be used in whole or in part to make principal
payments on REMIC Regular Interests issued without any discount or at an
insubstantial discount (if this occurs, it is likely that cash distributions
will exceed taxable income in later years). Taxable income may also be greater
in earlier years of certain REMIC issues as a result of the fact that interest
expense deductions, as a percentage of outstanding principal on REMIC Regular
Interest Securities, will typically increase over time as lower yielding
Securities are paid, whereas interest income with respect to loans will
generally remain constant over time as a percentage of loan principal.
 
     In any event, because the Holder of a residual interest is taxed on the net
income of the REMIC, the taxable income derived from a Residual Interest
Security in a given taxable year will not be equal to the taxable income
associated with investment in a corporate bond or stripped instrument having
similar cash flow characteristics and pretax yield. Therefore, the after-tax
yield on the Residual Interest Security may be less than that of such a bond or
instrument.
 
     Limitation on Losses.  In the opinion of Tax Counsel, the amount of the
REMIC's net loss that a Holder may take into account currently is limited to the
Holder's adjusted basis at the end of the calendar quarter in which such loss
arises. A Holder's basis in a Residual Interest Security will initially equal
such Holder's purchase price, and will subsequently be increased by the amount
of the REMIC's taxable income allocated to the Holder, and decreased (but not
below zero) by the amount of distributions made and the amount of the REMIC's
net loss allocated to the Holder. Any disallowed loss may be carried forward
indefinitely, but may be used only to offset income of the REMIC generated by
the same REMIC. The ability of Holders of Residual Interest Securities to deduct
net losses may be subject to additional limitations under the Code, as to which
such Holders should consult their tax advisers.
 
     Distributions.  In the opinion of Tax Counsel, distributions on a Residual
Interest Security (whether at their scheduled times or as a result of
prepayments) will generally not result in any additional taxable income or loss
to a Holder of a Residual Interest Security. If the amount of such payment
exceeds a Holder's adjusted basis in the Residual Interest Security, however,
the Holder will recognize gain (treated as gain from the sale of the Residual
Interest Security) to the extent of such excess.
 
     Sale or Exchange.  In the opinion of Tax Counsel, a Holder of a Residual
Interest Security will recognize gain or loss on the sale or exchange of a
Residual Interest Security equal to the difference, if any, between the amount
realized and such Holder's adjusted basis in the Residual Interest Security at
the time of such sale or exchange. Except to the extent provided in regulations,
which have not yet been issued, any loss upon disposition of a Residual Interest
Security will be disallowed if the selling Holder acquires any residual interest
in a REMIC or similar mortgage pool within six months before or after such
disposition.
 
     Excess Inclusions.  In the opinion of Tax Counsel, the portion of the REMIC
taxable income of a Holder of a Residual Interest Security consisting of "excess
inclusion" income may not be offset by other deductions or losses, including net
operating losses, on such Holder's federal income tax return. Further, if the
Holder of a Residual Interest Security is an organization subject to the tax on
unrelated business income imposed by Code Section 511, such Holder's excess
inclusion income will be treated as unrelated business taxable income of such
Holder. In addition, under Treasury regulations yet to be issued, if a real
estate investment trust, a regulated investment company, a common trust fund, or
certain cooperatives were to own a Residual Interest Security, a portion of
dividends (or other distributions) paid by the real estate investment trust (or
other entity) would be treated as excess inclusion income. If a Residual
Security is owned by a foreign person, excess inclusion income is subject to tax
at a rate of 30%, which may not be reduced by treaty, is not eligible for
treatment as "portfolio interest" and is subject to certain additional
limitations. See "Tax Treatment of Foreign Investors." The Small Business Job
Protection Act of 1996 has eliminated the special rule permitting Section 593
institutions ("thrift institutions") to use net operating losses and other
allowable deductions to offset their excess inclusion income from Residual
Interest Securities that have "significant value" within the meaning of the
REMIC Regulations, effective for taxable years beginning after December 31,
1995, except with respect to Residual Interest Securities continuously held by a
thrift institution since November 1, 1995.
 
     In addition, the Small Business Job Protection Act of 1996 provides three
rules for determining the effect on excess inclusions on the alternative minimum
taxable income of a residual Holder. First, alternative
                                       63
<PAGE>   160
 
minimum taxable income for such residual Holder is determined without regard to
the special rule that taxable income cannot be less than excess inclusions.
Second, a residual Holder's alternative minimum taxable income for a tax year
cannot be less than excess inclusions for the year. Third, the amount of any
alternative minimum tax net operating loss deductions must be computed without
regard to any excess inclusions. These rules are effective for tax years
beginning after December 31, 1986, unless a residual Holder elects to have such
rules apply only to tax years beginning after August 20, 1996.
 
     The excess inclusion portion of a REMIC's income is generally equal to the
excess, if any, of REMIC taxable income for the quarterly period allocable to a
Residual Interest Security, over the daily accruals for such quarterly period of
(i) 120% of the long term applicable federal rate on the Startup Day multiplied
by (ii) the adjusted issue price of such Residual Interest Security at the
beginning of such quarterly period. The adjusted issue price of a Residual
Interest at the beginning of each calendar quarter will equal its issue price
(calculated in a manner analogous to the determination of the issue price of a
Regular Interest), increased by the aggregate of the daily accruals for prior
calendar quarters, and decreased (but not below zero) by the amount of loss
allocated to a Holder and the amount of distributions made on the Residual
Interest Security before the beginning of the quarter. The long-term federal
rate, which is announced monthly by the Treasury Department, is an interest rate
that is based on the average market yield of outstanding marketable obligations
of the United States government having remaining maturities in excess of nine
years.
 
     Under the REMIC Regulations, in certain circumstances, transfers of
Residual Securities may be disregarded. See " -- Restrictions on Ownership and
Transfer of Residual Interest Securities" and " -- Tax Treatment of Foreign
Investors" below.
 
     Restrictions on Ownership and Transfer of Residual Interest Securities. As
a condition to qualification as a REMIC, reasonable arrangements must be made to
prevent the ownership of a REMIC residual interest by any "Disqualified
Organization." Disqualified Organizations include the United States, any State
or political subdivision thereof, any foreign government, any international
organization, or any agency or instrumentality of any of the foregoing, a rural
electric or telephone cooperative described in Section 1381(a)(2)(C) of the
Code, or any entity exempt from the tax imposed by Sections 1-1399 of the Code,
if such entity is not subject to tax on its unrelated business income.
Accordingly, the applicable Pooling and Servicing Agreement will prohibit
Disqualified Organizations from owning a Residual Interest Security. In
addition, no transfer of a Residual Interest Security will be permitted unless
the proposed transferee shall have furnished to the Trustee an affidavit
representing and warranting that it is neither a Disqualified Organization nor
an agent or nominee acting on behalf of a Disqualified Organization.
 
     If a Residual Interest Security is transferred to a Disqualified
Organization after March 31, 1988 (in violation of the restrictions set forth
above), a substantial tax will be imposed on the transferor of such Residual
Interest Security at the time of the transfer. In addition, if a Disqualified
Organization holds an interest in a pass-through entity after March 31, 1988
(including, among others, a partnership, trust, real estate investment trust,
regulated investment company, or any person holding as nominee), that owns a
Residual Interest Security, the pass-through entity will be required to pay an
annual tax on its allocable share of the excess inclusion income of the REMIC.
 
     Under the REMIC Regulations, if a Residual Interest Security is a
"noneconomic residual interest," as described below, a transfer of a Residual
Interest Security to a United States person will be disregarded for all federal
tax purposes unless no significant purpose of the transfer was to impede the
assessment or collection of tax. A Residual Interest Security is a "noneconomic
residual interest" unless, at the time of the transfer (i) the present value of
the expected future distributions on the Residual Interest Security at least
equals the product of the present value of the anticipated excess inclusions and
the highest rate of tax 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 the taxes accrue on the anticipated
excess inclusions in an amount sufficient to satisfy the accrued taxes. If a
transfer of a Residual Interest is disregarded, the transferor would be liable
for any federal income tax imposed upon taxable income derived by the transferee
from the REMIC. The REMIC Regulations provide no guidance as to how to determine
if a significant purpose of a transfer is to impede the assessment or collection
of tax. A similar type of limitation
 
                                       64
<PAGE>   161
 
exists with respect to certain transfers of residual interests by foreign
persons to United States persons. See " -- Tax Treatment of Foreign Investors."
 
     Mark to Market Rules.  Prospective purchasers of a REMIC Residual Interest
Security should be aware that the IRS recently finalized regulations (the "Final
Mark-to-Market Regulations"), which provide that a REMIC Residual Interest
Security acquired after January 3, 1995 cannot be marked-to-market. Prospective
purchasers of a REMIC Residual Interest Security should consult their tax
advisors regarding the possible application of the Mark to Market Regulations.
 
ADMINISTRATIVE MATTERS
 
     The REMIC's books must be maintained on a calendar year basis and the REMIC
must file an annual federal income tax return. The REMIC will also be subject to
the procedural and administrative rules of the Code applicable to partnerships,
including the determination of any adjustments to, among other things, items of
REMIC income, gain, loss, deduction, or credit, by the IRS in a unified
administrative proceeding.
 
TAX STATUS AS A GRANTOR TRUST
 
     General.  As further specified in the related Prospectus Supplement, if a
REMIC election is not made and the Trust Fund is not structured as a
partnership, then, in the opinion of Tax Counsel, the Trust Fund relating to a
Series of Securities will be classified for federal income tax purposes as a
grantor trust under Subpart E, Part 1 of Subchapter J of the Code and not as an
association taxable as a corporation (the Securities of such Series,
"Pass-Through Securities"). In some Series there will be no separation of the
principal and interest payments on the Loans. In such circumstances, a Holder
will be considered to have purchased a pro rata undivided interest in each of
the Loans. In other cases ("Stripped Securities"), sale of the Securities will
produce a separation in the ownership of all or a portion of the principal
payments from all or a portion of the interest payments on the Loans.
 
     In the opinion of Tax Counsel, each Holder must report on its federal
income tax return its share of the gross income derived from the Loans (not
reduced by the amount payable as fees to the applicable Trustee and the Servicer
and similar fees (collectively, the "Servicing Fee")), at the same time and in
the same manner as such items would have been reported under the Holder's tax
accounting method had it held its interest in the Loans directly, received
directly its share of the amounts received with respect to the Loans, and paid
directly its share of the Servicing Fees. In the case of Pass-Through Securities
other than Stripped Securities, such income will consist of a pro rata share of
all of the income derived from all of the Loans and, in the case of Stripped
Securities, such income will consist of a pro rata share of the income derived
from each stripped bond or stripped coupon in which the Holder owns an interest.
The Holder of a Security will generally be entitled to deduct such Servicing
Fees under Section 162 or Section 212 of the Code to the extent that such
Servicing Fees represent "reasonable" compensation for the services rendered by
the applicable Trustee and the Servicer (or third parties that are compensated
for the performance of services). In the case of a noncorporate Holder, however,
Servicing Fees (to the extent not otherwise disallowed, e.g., because they
exceed reasonable compensation) will be deductible in computing such Holder's
regular tax liability only to the extent that such fees, when added to other
miscellaneous itemized deductions, exceed 2% of adjusted gross income and may
not be deductible to any extent in computing such Holder's alternative minimum
tax liability. In addition, for taxable years beginning after December 31, 1990,
the amount of itemized deductions otherwise allowable for the taxable year for
an individual whose adjusted gross income exceeds the applicable amount (which
amount will be adjusted for inflation in taxable years beginning after 1990)
will be reduced by the lesser of (i) 3% of the excess of adjusted gross income
over the applicable amount or (ii) 80% of the amount of itemized deductions
otherwise allowable for such taxable year.
 
     Discount or Premium on Pass-Through Securities.  In the opinion of Tax
Counsel, the Holder's purchase price of a Pass-Through Security is to be
allocated among the Loans in proportion to their fair market values, determined
as of the time of purchase of the Securities. In the typical case, the Trustee
(to the extent necessary to fulfill its reporting obligations) will treat each
Loan as having a fair market value proportional to the share of the aggregate
Principal Balances of all of the Loans that it represents, since the Securities,
unless otherwise specified in the related Prospectus Supplement, will have a
relatively uniform interest rate and other common characteristics. To the extent
that the portion of the purchase price of a Pass-
                                       65
<PAGE>   162
 
Through Security allocated to a Loan (other than to a right to receive any
accrued interest thereon and any undistributed principal payments) is less than
or greater than the portion of the Principal Balance of the Loan allocable to
the Security, the interest in the Loan allocable to the Pass-Through Security
will be deemed to have been acquired at a discount or premium, respectively.
 
     The treatment of any discount will depend on whether the discount
represents OID or market discount. In the case of a Loan with OID in excess of a
prescribed de minimis amount or a Stripped Security, a Holder of a Security will
be required to report as interest income in each taxable year its share of the
amount of OID that accrues during that year in the manner described above. OID
with respect to a Loan could arise, for example, by virtue of the financing of
points by the originator of the Loan, or by virtue of the charging of points by
the originator of the Loan in an amount greater than a statutory de minimis
exception, in circumstances under which the points are not currently deductible
pursuant to applicable Code provisions. Any market discount or premium on a Loan
will be includible in income, generally in the manner described above, except
that in the case of Pass-Through Securities, market discount is calculated with
respect to the Loans underlying the Certificate, rather than with respect to the
Security. A Holder that acquires an interest in a Loan originated after July 18,
1984 with more than a de minimis amount of market discount (generally, the
excess of the principal amount of the Loan over the purchaser's allocable
purchase price) will be required to include accrued market discount in income in
the manner set forth above. See " -- Taxation of Debt Securities; Market
Discount" and " -- Premium" above.
 
     In the case of market discount on a Pass-Through Security attributable to
Loans originated on or before July 18, 1984, the Holder generally will be
required to allocate the portion of such discount that is allocable to a loan
among the principal payments on the Loan and to include the discount allocable
to each principal payment in ordinary income at the time such principal payment
is made. Such treatment would generally result in discount being included in
income at a slower rate than discount would be required to be included in income
using the method described in the preceding paragraph.
 
     Stripped Securities.  A Stripped Security may represent a right to receive
only a portion of the interest payments on the Loans, a right to receive only
principal payments on the Loans, or a right to receive certain payments of both
interest and principal. Certain Stripped Securities ("Ratio Strip Securities")
may represent a right to receive differing percentages of both the interest and
principal on each Loan. Pursuant to Section 1286 of the Code, the separation of
ownership of the right to receive some or all of the interest payments on an
obligation from ownership of the right to receive some or all of the principal
payments results in the creation of "stripped bonds" with respect to principal
payments and "stripped coupons" with respect to interest payments. Section 1286
of the Code applies the OID rules to stripped bonds and stripped coupons. For
purposes of computing original issue discount, a stripped bond or a stripped
coupon is treated as a debt instrument issued on the date that such stripped
interest is purchased with an issue price equal to its purchase price or, if
more than one stripped interest is purchased, the ratable share of the purchase
price allocable to such stripped interest.
 
     Servicing fees in excess of reasonable servicing fees (the "excess
servicing fee") will be treated under the stripped bond rules. If the excess
servicing fee is less than 100 basis points (i.e., 1% interest on the Loan's
Principal Balance) or the Securities are initially sold with a de minimis
discount (assuming no prepayment assumption is required), any non-de minimis
discount arising from a subsequent transfer of the Securities should be treated
as market discount. The IRS appears to require that reasonable servicing fees be
calculated on a Loan by Loan basis, which could result in some Loans being
treated as having more than 100 basis points of interest stripped off.
 
     The Code, OID Regulations and judicial decisions provide no direct guidance
as to how the interest and original issue discount rules are to apply to
Stripped Securities and other Pass-Through Securities. Under the method
described above for Pay-Through Securities (the "Cash Flow Bond Method"), a
prepayment assumption is used and periodic recalculations are made that take
into account with respect to each accrual period the effect of prepayments
during such period. However, the 1986 Act does not, absent Treasury regulations,
appear specifically to cover instruments such as the Stripped Securities, which
technically represent ownership interests in the underlying Loans, rather than
being debt instruments "secured by" those loans. Nevertheless, it is believed
that the Cash Flow Bond Method is a reasonable method of reporting
 
                                       66
<PAGE>   163
 
income for such Securities, and it is expected that OID will be reported on that
basis unless otherwise specified in the related Prospectus Supplement. In
applying the calculation to Pass-Through Securities, the Trustee will treat all
payments to be received by a Holder with respect to the underlying Loans as
payments on a single installment obligation. The IRS could, however, assert that
original issue discount must be calculated separately for each Loan underlying a
Security.
 
     Under certain circumstances, if the Loans prepay at a rate faster than the
Prepayment Assumption, the use of the Cash Flow Bond Method may accelerate a
Holder's recognition of income. If, however, the Loans prepay at a rate slower
than the Prepayment Assumption, in some circumstances the use of this method may
decelerate a Holder's recognition of income.
 
     In the case of a Stripped Security that is an Interest Weighted Security,
the applicable Trustee intends, absent contrary authority, to report income to
Holders as OID, in the manner described above for Interest Weighted Securities.
 
     Possible Alternative Characterizations.  The characterizations of the
Stripped Securities described above are not the only possible interpretations of
the applicable Code provisions. Among other possibilities, the Internal Revenue
Service could contend that (i) in certain Series, each non-Interest Weighted
Security is composed of an unstripped undivided ownership interest in Loans and
an installment obligation consisting of stripped principal payments; (ii) the
non-Interest Weighted Securities are subject to the contingent payment
provisions of the Proposed Regulations; or (iii) each Interest Weighted Stripped
Security is composed of an unstripped undivided ownership interest in Loans and
an installment obligation consisting of stripped interest payments.
 
     Given the variety of alternatives for treatment of the Stripped Securities
and the different federal income tax consequences that result from each
alternative, potential purchasers are urged to consult their own tax advisers
regarding the proper treatment of the Securities for federal income tax
purposes.
 
     Character as Qualifying Loans.  In the case of Stripped Securities, there
is no specific legal authority existing regarding whether the character of the
Securities, for federal income tax purposes, will be the same as the Loans. The
IRS could take the position that the Loans character is not carried over to the
Securities in such circumstances. Pass-Through Securities will be, and, although
the matter is not free from doubt, Stripped Securities should be considered to
represent "real estate assets" within the meaning of Section 856(c)(4)(A) of the
Code, and "loans secured by an interest in real property" within the meaning of
Section 7701(a)(19)(C)(v) of the Code; and interest income attributable to the
Securities should be considered to represent "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. Reserves or funds underlying the Securities
may cause a proportionate reduction in the above-described qualifying status
categories of Securities.
 
SALE OR EXCHANGE
 
     Subject to the discussion below with respect to Trust Funds as to which a
partnership election is made, in the opinion of Tax Counsel, a Holder's tax
basis in its Security is the price such Holder pays for a Security, plus amounts
of original issue or market discount included in income and reduced by any
payments received (other than qualified stated interest payments) and any
amortized premium. Gain or loss recognized on a sale, exchange, or redemption of
a Security, measured by the difference between the amount realized and the
Security's basis as so adjusted, will generally be capital gain or loss,
assuming that the Security is held as a capital asset and will generally be
long-term capital gain or loss if the holding period of the Security is one year
or more and short-term capital gain or loss if the holding period of the
Security is less than one year. Non-corporate taxpayers are subject to reduced
maximum rates on long-term capital gains and are generally subject to tax at
ordinary income rates on short-term capital gains. The deductibility of capital
losses is subject to certain limitations. Prospective investors should consult
their own tax advisors concerning these tax law provisions.
 
     In the case of a Security held by a bank, thrift, or similar institution
described in Section 582 of the Code, however, gain or loss realized on the sale
or exchange of a Regular Interest Security will be taxable as ordinary income or
loss. In addition, gain from the disposition of a Regular Interest Security that
might otherwise be
                                       67
<PAGE>   164
 
capital gain will be treated as ordinary income to the extent of the excess, if
any, of (i) the amount that would have been includible in the Holder's income if
the yield on such Regular Interest Security had equaled 110% of the applicable
federal rate as of the beginning of such Holder's holding period, over the
amount of ordinary income actually recognized by the Holder with respect to such
Regular Interest Security.
 
MISCELLANEOUS TAX ASPECTS
 
     Backup Withholding.  Subject to the discussion below with respect to Trust
Funds as to which a partnership election is made, a Holder, other than a Holder
of a REMIC Residual Security, may, under certain circumstances, be subject to
"backup withholding" at a rate of 31% with respect to distributions or the
proceeds of a sale of certificates to or through brokers that represent interest
or original issue discount on the Securities. This withholding generally applies
if the Holder of a Security (i) fails to furnish the applicable Trustee with its
taxpayer identification number (the "TIN"); (ii) furnishes the applicable
Trustee an incorrect TIN; (iii) fails to report properly interest, dividends or
other "reportable payments" as defined in the Code; or (iv) under certain
circumstances, fails to provide the applicable Trustee or such Holder's
securities broker with a certified statement, signed under penalty of perjury,
that the TIN provided is its correct number and that the Holder is not subject
to backup withholding. Backup withholding will not apply, however, with respect
to certain payments made to Holders, including payments to certain exempt
recipients (such as exempt organizations) and to certain Nonresidents (as
defined below). Holders should consult their tax advisers as to their
qualification for exemption from backup withholding and the procedure for
obtaining the exemption.
 
     The applicable Trustee will report to the Holders and to the Servicer for
each calendar year the amount of any "reportable payments" during such year and
the amount of tax withheld, if any, with respect to payments on the Securities.
 
NEW WITHHOLDING REGULATIONS
 
     On October 6, 1997, the Treasury Department issued new regulations (the
"New Regulations"), which make certain modifications to the withholding, backup
withholding and information reporting rules described above. The New Regulations
attempt to unify certification requirements and modify reliance standards. The
New Regulations will generally be effective for payments made after December 31,
1999, subject to certain transition rules. Prospective investors are urged to
consult their own tax advisors regarding the New Regulations.
 
TAX TREATMENT OF FOREIGN INVESTORS
 
     Subject to the discussion below with respect to Trust Funds as to which a
partnership election is made, under the Code, unless interest (including OID)
paid on a Security (other than a Residual Interest Security) is considered to be
"effectively connected" with a trade or business conducted in the United States
by a nonresident alien individual, foreign partnership or foreign corporation
("Nonresidents"), in the opinion of Tax Counsel, such interest will normally
qualify as portfolio interest (except where (i) the recipient is a holder,
directly or by attribution, of 10% or more of the capital or profits interest in
the issuer, or (ii) the recipient is a controlled foreign corporation to which
the issuer is a related person) and will be exempt from federal income tax. Upon
receipt of appropriate ownership statements, the issuer normally will be
relieved of obligations to withhold tax from such interest payments. These
provisions supersede the generally applicable provisions of United States law
that would otherwise require the issuer to withhold at a 30% rate (unless such
rate were reduced or eliminated by an applicable tax treaty) on, among other
things, interest and other fixed or determinable, annual or periodic income paid
to Nonresidents. Holders of Pass-Through Securities and Stripped Securities,
including Ratio Strip Securities, however, may be subject to withholding to the
extent that the Loans were originated on or before July 18, 1984.
 
     Interest and OID of Holders who are foreign persons are not subject to
withholding if they are effectively connected with a United States business
conducted by the Holder. They will, however, generally be subject to the regular
United States income tax.
 
     Payments to Holders of Residual Interest Securities who are foreign persons
will generally be treated as interest for purposes of the 30% (or lower treaty
rate) United States withholding tax. Holders should assume
                                       68
<PAGE>   165
 
that such income does not qualify for exemption from United States withholding
tax as "portfolio interest." It is clear that, to the extent that a payment
represents a portion of REMIC taxable income that constitutes excess inclusion
income, a Holder of a Residual Interest Security will not be entitled to an
exemption from or reduction of the 30% (or lower treaty rate) withholding tax
rule. If the payments are subject to United States withholding tax, they
generally will be taken into account for withholding tax purposes only when paid
or distributed (or when the Residual Interest Security is disposed of). The
Treasury has statutory authority, however, to promulgate regulations that would
require such amounts to be taken into account at an earlier time in order to
prevent the avoidance of tax. Such regulations could, for example, require
withholding prior to the distribution of cash in the case of Residual Interest
Securities that do not have significant value. Under the REMIC Regulations, if a
Residual Interest Security has tax avoidance potential, a transfer of a Residual
Interest Security to a Nonresident will be disregarded for all federal tax
purposes. A Residual Interest Security has tax avoidance potential unless, at
the time of the transfer the transferor reasonably expects that the REMIC will
distribute to the transferee residual interest Holder amounts that will equal at
least 30% of each excess inclusion, and that such amounts will be distributed at
or after the time at which the excess inclusions accrue and not later than the
calendar year following the calendar year of accrual. If a Nonresident transfers
a Residual Interest Security to a United States person, and if the transfer has
the effect of allowing the transferor to avoid tax on accrued excess inclusions,
then the transfer is disregarded and the transferor continues to be treated as
the owner of the Residual Interest Security for purposes of the withholding tax
provisions of the Code. See " -- Excess Inclusions."
 
TAX CHARACTERIZATION OF THE TRUST FUND AS A PARTNERSHIP
 
     Tax Counsel is of the opinion that a Trust Fund structured as a partnership
will not be an association (or publicly traded partnership) taxable as a
corporation for federal income tax purposes. This opinion is based on the
assumption that the terms of the Trust Agreement and related documents will be
complied with, and on counsel's conclusions that the nature of the income of the
Trust Fund will exempt it from the rule that certain publicly traded
partnerships are taxable as corporations or the issuance of the Certificates has
been structured as a private placement under an IRS safe harbor, so that the
Trust Fund will not be characterized as a publicly traded partnership taxable as
a corporation.
 
     If the Trust Fund were taxable as a corporation for federal income tax
purposes, in the opinion of Tax Counsel, the Trust Fund would be subject to
corporate income tax on its taxable income. The Trust Fund's taxable income
would include all its income, possibly reduced by its interest expense on the
Notes. Any such corporate income tax could materially reduce cash available to
make payments on the Notes and distributions on the Certificates, and
Certificateholders could be liable for any such tax that is unpaid by the Trust
Fund.
 
TAX CONSEQUENCES TO HOLDERS OF THE NOTES
 
     Treatment of the Notes as Indebtedness.  The Trust Fund will agree, and the
Noteholders will agree by their purchase of Notes, to treat the Notes as debt
for federal income tax purposes. In such a circumstance, Tax Counsel is, except
as otherwise provided in the related Prospectus Supplement, of the opinion that
the Notes will be classified as debt for federal income tax purposes. The
discussion below assumes this characterization of the Notes is correct.
 
     OID, Indexed Securities, etc.  The discussion below assumes that all
payments on the Notes are denominated in U.S. dollars, and that the Notes are
not Indexed Securities or Strip Notes. Moreover, the discussion assumes that the
interest formula for the Notes meets the requirements for "qualified stated
interest" under the OID Regulations, and that any OID on the Notes (i.e., any
excess of the principal amount of the Notes over their issue price) does not
exceed a de minimis amount (i.e., 0.25% of their principal amount multiplied by
the number of full years included in their term), all within the meaning of the
OID regulations. If these conditions are not satisfied with respect to any given
series of Notes, additional tax considerations with respect to such Notes will
be disclosed in the applicable Prospectus Supplement.
 
     Interest Income on the Notes.  Based on the above assumptions, except as
discussed in the following paragraph, in the opinion of Tax Counsel, the Notes
will not be considered issued with OID. The stated interest thereon will be
taxable to a Noteholder as ordinary interest income when received or accrued in
accordance with such Noteholder's method of tax accounting. Under the OID
Regulations, a Holder of a
                                       69
<PAGE>   166
 
Note issued with a de minimis amount of OID must include such OID in income, on
a pro rata basis, as principal payments are made on the Note. It is believed
that any prepayment premium paid as a result of a mandatory redemption will be
taxable as contingent interest when it becomes fixed and unconditionally
payable. A purchaser who buys a Note for more or less than its principal amount
will generally be subject, respectively, to the premium amortization or market
discount rules of the Code.
 
     A Holder of a Note that has a fixed maturity date of not more than one year
from the issue date of such Note (a "Short-Term Note") may be subject to special
rules. An accrual basis Holder of a Short-Term Note (and certain cash method
Holders, including regulated investment companies, as set forth in Section 1281
of the Code) generally would be required to report interest income as interest
accrues on a straight-line basis over the term of each interest period. Other
cash basis Holders of a Short-Term Note would, in general, be required to report
interest income as interest is paid (or, if earlier, upon the taxable
disposition of the Short-Term Note). However, a cash basis Holder of a
Short-Term Note reporting interest income as it is paid may be required to defer
a portion of any interest expense otherwise deductible on indebtedness incurred
to purchase or carry the Short-Term Note until the taxable disposition of the
Short-Term Note. A cash basis taxpayer may elect under Section 1281 of the Code
to accrue interest income on all nongovernment debt obligations with a term of
one year or less, in which case the taxpayer would include interest on the
Short-Term Note in income as it accrues, but would not be subject to the
interest expense deferral rule referred to in the preceding sentence. Certain
special rules apply if a Short-Term Note is purchased for more or less than its
principal amount.
 
     Sale or Other Disposition.  In the opinion of Tax Counsel, if a Noteholder
sells a Note, the Holder will recognize gain or loss in an amount equal to the
difference between the amount realized on the sale and the Holder's adjusted tax
basis in the Note. The adjusted tax basis of a Note to a particular Noteholder
will equal the Holder's cost for the Note, increased by any market discount,
acquisition discount, OID and gain previously included by such Noteholder in
income with respect to the Note and decreased by the amount of bond premium (if
any) previously amortized and by the amount of principal payments previously
received by such Noteholder with respect to such Note. Any such gain or loss
will be capital gain or loss if the Note was held as a capital asset, except for
gain representing accrued interest and accrued market discount not previously
included in income. Capital losses generally may be used only to offset capital
gains.
 
     Foreign Holders. In the opinion of Tax Counsel, interest payments made (or
accrued) to a Noteholder who is a nonresident alien, foreign corporation or
other non-United States person (a "foreign person") generally will be considered
"portfolio interest," and generally will not be subject to United States federal
income tax and withholding tax, if the interest is not effectively connected
with the conduct of a trade or business within the United States by the foreign
person and the foreign person (i) is not actually or constructively a "10
percent shareholder" of the Trust Fund or the Seller (including a Holder of 10%
of the outstanding Certificates) or a "controlled foreign corporation" with
respect to which the Trust Fund or the Seller is a "related person" within the
meaning of the Code and (ii) provides the Trustee or other person who is
otherwise required to withhold U.S. tax with respect to the Notes with an
appropriate statement (on Form W-8 or a similar form), signed under penalties of
perjury, certifying that the beneficial owner of the Note is a foreign person
and providing the foreign person's name and address. If a Note is held through a
securities clearing organization or certain other financial institutions, the
organization or institution may provide the relevant signed statement to the
withholding agent; in that case, however, the signed statement must be
accompanied by a Form W-8 or substitute form provided by the foreign person that
owns the Note. If such interest is not portfolio interest, then it will be
subject to United States federal income and withholding tax at a rate of 30
percent, unless reduced or eliminated pursuant to an applicable tax treaty.
 
     Any capital gain realized on the sale, redemption, retirement or other
taxable disposition of a Note by a foreign person will be exempt from United
States federal income and withholding tax; provided, that (i) such gain is not
effectively connected with the conduct of a trade or business in the United
States by the foreign person and (ii) in the case of an individual foreign
person, the foreign person is not present in the United States for 183 days or
more in the taxable year.
 
     Backup Withholding.  Each Holder of a Note (other than an exempt Holder
such as a corporation, tax-exempt organization, qualified pension and
profit-sharing trust, individual retirement account or nonresident
 
                                       70
<PAGE>   167
 
alien who provides certification as to status as a nonresident) will be required
to provide, under penalties of perjury, a certificate containing the Holder's
name, address, correct federal taxpayer identification number and a statement
that the Holder is not subject to backup withholding. Should a nonexempt
Noteholder fail to provide the required certification, the Trust Fund will be
required to withhold 31 percent of the amount otherwise payable to the Holder,
and remit the withheld amount to the IRS as a credit against the Holder's
federal income tax liability.
 
     The New Regulations described herein make certain modifications to the
backup withholding and information reporting rules. The New Regulations
generally will be effective for payments made after December 31, 1999, subject
to certain transition rules. Prospective investors are urged to consult their
own tax advisors regarding the New Regulations.
 
     Possible Alternative Treatments of the Notes.  If, contrary to the opinion
of Tax Counsel, the IRS successfully asserted that one or more of the Notes did
not represent debt for federal income tax purposes, the Notes might be treated
as equity interests in the Trust Fund. If so treated, the Trust Fund might be
taxable as a corporation with the adverse consequences described above (and the
taxable corporation would not be able to reduce its taxable income by deductions
for interest expense on Notes recharacterized as equity). Alternatively, and
most likely in the view of Tax Counsel, the Trust Fund might be treated as a
publicly traded partnership that would not be taxable as a corporation because
it would meet certain qualifying income tests. Nonetheless, treatment of the
Notes as equity interests in such a publicly traded partnership could have
adverse tax consequences to certain Holders. For example, income to certain
tax-exempt entities (including pension funds) would be "unrelated business
taxable income," income to foreign Holders generally would be subject to U.S.
tax and U.S. tax return filing and withholding requirements, and individual
Holders might be subject to certain limitations on their ability to deduct their
share of the Trust Fund's expenses.
 
TAX CONSEQUENCES TO HOLDERS OF THE CERTIFICATES
 
     Treatment of the Trust Fund as a Partnership.  The Trust Fund and the
Servicer will agree, and the Certificateholders will agree by their purchase of
Certificates, to treat the Trust Fund as a partnership for purposes of federal
and state income tax, franchise tax and any other tax measured in whole or in
part by income, with the assets of the partnership being the assets held by the
Trust Fund, the partners of the partnership being the Certificateholders, and
the Notes being debt of the partnership. However, the proper characterization of
the arrangement involving the Trust Fund, the Certificates, the Notes, the Trust
Fund and the Servicer is not clear because there is no authority on transactions
closely comparable to that contemplated herein.
 
     A variety of alternative characterizations are possible. For example,
because the Certificates have certain features characteristic of debt, the
Certificates might be considered debt of the Trust Fund. Any such
characterization would not result in materially adverse tax consequences to
Certificateholders as compared to the consequences from treatment of the
Certificates as equity in a partnership, described below. The following
discussion assumes that the Certificates represent equity interests in a
partnership.
 
     Indexed Securities, etc.  The following discussion assumes that all
payments on the Certificates are denominated in U.S. dollars, none of the
Certificates are Indexed Securities or Strip Certificates, and that a Series of
Securities includes a single Class of Certificates. If these conditions are not
satisfied with respect to any given Series of Certificates, additional tax
considerations with respect to such Certificates will be disclosed in the
applicable Prospectus Supplement.
 
     Partnership Taxation.  If the Trust Fund is a partnership, in the opinion
of Tax Counsel, the Trust Fund will not be subject to federal income tax.
Rather, in the opinion of Tax Counsel, each Certificateholder will be required
to separately take into account such Holder's allocated share of income, gains,
losses, deductions and credits of the Trust Fund. The Trust Fund's income will
consist primarily of interest and finance charges earned on the Loans (including
appropriate adjustments for market discount, OID and bond premium) and any gain
upon collection or disposition of Loans. The Trust Fund's deductions will
consist primarily of interest accruing with respect to the Notes, servicing and
other fees, and losses or deductions upon collection or disposition of Loans.
 
                                       71
<PAGE>   168
 
     In the opinion of Tax Counsel, the tax items of a partnership are allocable
to the partners in accordance with the Code, Treasury regulations and the
partnership agreement (here, the Trust Agreement and related documents). The
Trust Agreement will provide, in general, that the Certificateholders will be
allocated taxable income of the Trust Fund for each month equal to the sum of
(i) the interest that accrues on the Certificates in accordance with their terms
for such month, including interest accruing at the Pass-Through Rate for such
month and interest on amounts previously due on the Certificates but not yet
distributed; (ii) any Trust Fund income attributable to discount on the Loans
that corresponds to any excess of the principal amount of the Certificates over
their initial issue price (iii) prepayment premium payable to the
Certificateholders for such month; and (iv) any other amounts of income payable
to the Certificateholders for such month. Such allocation will be reduced by any
amortization by the Trust Fund of premium on Loans that corresponds to any
excess of the issue price of Certificates over their principal amount. All
remaining taxable income of the Trust Fund will be allocated to the Depositor.
Based on the economic arrangement of the parties, in the opinion of Tax Counsel,
this approach for allocating Trust Fund income should be permissible under
applicable Treasury regulations, although no assurance can be given that the IRS
would not require a greater amount of income to be allocated to
Certificateholders. Moreover, in the opinion of Tax Counsel, even under the
foregoing method of allocation, Certificateholders may be allocated income equal
to the entire Pass-Through Rate plus the other items described above even though
the Trust Fund might not have sufficient cash to make current cash distributions
of such amount. Thus, cash basis Holders will in effect be required to report
income from the Certificates on the accrual basis and Certificateholders may
become liable for taxes on Trust Fund income even if they have not received cash
from the Trust Fund to pay such taxes. In addition, because tax allocations and
tax reporting will be done on a uniform basis for all Certificateholders but
Certificateholders may be purchasing Certificates at different times and at
different prices, Certificateholders may be required to report on their tax
returns taxable income that is greater or less than the amount reported to them
by the Trust Fund.
 
     In the opinion of Tax Counsel, all of the taxable income allocated to a
Certificateholder that is a pension, profit sharing or employee benefit plan or
other tax-exempt entity (including an individual retirement account) will
constitute "unrelated business taxable income" generally taxable to such a
Holder under the Code.
 
     In the opinion of Tax Counsel, an individual taxpayer's share of expenses
of the Trust Fund (including fees to the Servicer but not interest expense)
would be miscellaneous itemized deductions. Such deductions might be disallowed
to the individual in whole or in part and might result in such Holder being
taxed on an amount of income that exceeds the amount of cash actually
distributed to such Holder over the life of the Trust Fund.
 
     The Trust Fund intends to make all tax calculations relating to income and
allocations to Certificateholders on an aggregate basis. If the IRS were to
require that such calculations be made separately for each Loan, the Trust Fund
might be required to incur additional expense but it is believed that there
would not be a material adverse effect on Certificateholders.
 
     Discount and Premium.  It is believed that the Loans were not issued with
OID, and, therefore, the Trust Fund should not have OID income. However, the
purchase price paid by the Trust Fund for the Loans may be greater or less than
the remaining Principal Balance of the Loans at the time of purchase. If so, in
the opinion of Tax Counsel, the Loan will have been acquired at a premium or
discount, as the case may be. (As indicated above, the Trust Fund will make this
calculation on an aggregate basis, but might be required to recompute it on a
Loan by Loan basis.)
 
     If the Trust Fund acquires the Loans at a market discount or premium, the
Trust Fund will elect to include any such discount in income currently as it
accrues over the life of the Loans or to offset any such premium against
interest income on the Loans. As indicated above, a portion of such market
discount income or premium deduction may be allocated to Certificateholders.
 
     Section 708 Termination.  In the opinion of Tax Counsel, under Section 708
of the Code, the Trust Fund will be deemed to terminate for federal income tax
purposes if 50% or more of the capital and profits interests in the Trust Fund
are sold or exchanged within a 12-month period. Pursuant to final Treasury
regulations issued May 9, 1997 under Section 708 of the Code, if such a
termination occurs, the Trust Fund
                                       72
<PAGE>   169
 
(the "old partnership") would be deemed to contribute its assets to a new
partnership (the "new partnership") in exchange for interests in the new
partnership. Such interests would be deemed distributed to the partners of the
old partnership in liquidation thereof, which would not constitute a sale or
exchange.
 
     Disposition of Certificates.  Generally, in the opinion of Tax Counsel,
capital gain or loss will be recognized on a sale of Certificates in an amount
equal to the difference between the amount realized and the seller's tax basis
in the Certificates sold. A Certificateholder's tax basis in a Certificate will
generally equal the Holder's cost increased by the Holder's share of Trust Fund
income (includible in income) and decreased by any distributions received with
respect to such Certificate. In addition, both the tax basis in the Certificates
and the amount realized on a sale of a Certificate would include the Holder's
share of the Notes and other liabilities of the Trust Fund. A Holder acquiring
Certificates at different prices may be required to maintain a single aggregate
adjusted tax basis in such Certificates, and, upon sale or other disposition of
some of the Certificates, allocate a portion of such aggregate tax basis to the
Certificates sold (rather than maintaining a separate tax basis in each
Certificate for purposes of computing gain or loss on a sale of that
Certificate).
 
     Any gain on the sale of a Certificate attributable to the Holder's share of
unrecognized accrued market discount on the Loans would generally be treated as
ordinary income to the Holder and would give rise to special tax reporting
requirements. The Trust Fund does not expect to have any other assets that would
give rise to such special reporting requirements. Thus, to avoid those special
reporting requirements, the Trust Fund will elect to include market discount in
income as it accrues.
 
     If a Certificateholder is required to recognize an aggregate amount of
income (not including income attributable to disallowed itemized deductions
described above) over the life of the Certificates that exceeds the aggregate
cash distributions with respect thereto, such excess will generally give rise to
a capital loss upon the retirement of the Certificates.
 
     Allocations Between Transferors and Transferees.  In general, the Trust
Fund's taxable income and losses will be determined monthly and the tax items
for a particular calendar month will be apportioned among the Certificateholders
in proportion to the principal amount of Certificates owned by them as of the
close of the last day of such month. As a result, a Holder purchasing
Certificates may be allocated tax items (which will affect its tax liability and
tax basis) attributable to periods before the actual transaction.
 
     The use of such a monthly convention may not be permitted by existing
regulations. If a monthly convention is not allowed (or only applies to
transfers of less than all of the partner's interest), taxable income or losses
of the Trust Fund might be reallocated among the Certificateholders. The Trust
Fund's method of allocation between transferors and transferees may be revised
to conform to a method permitted by future regulations.
 
     Section 754 Election.  In the event that a Certificateholder sells its
Certificates at a profit (loss), the purchasing Certificateholder will have a
higher (lower) basis in the Certificates than the selling Certificateholder had.
The tax basis of the Trust Fund's assets will not be adjusted to reflect that
higher (or lower) basis unless the Trust Fund were to file an election under
Section 754 of the Code. In order to avoid the administrative complexities that
would be involved in keeping accurate accounting records, as well as potentially
onerous information reporting requirements, the Trust Fund will not make such
election. As a result, Certificateholders might be allocated a greater or lesser
amount of Trust Fund income than would be appropriate based on their own
purchase price for Certificates.
 
     Administrative Matters.  The Trustee is required to keep or have kept
complete and accurate books of the Trust Fund. Such books will be maintained for
financial reporting and tax purposes on an accrual basis and the fiscal year of
the Trust Fund will be the calendar year. The Trustee will file a partnership
information return (IRS Form 1065) with the IRS for each taxable year of the
Trust Fund and will report each Certificateholder's allocable share of items of
Trust Fund income and expense to Holders and the IRS on Schedule K-1. The Trust
Fund will provide the Schedule K-l information to nominees that fail to provide
the Trust Fund with the information statement described below and such nominees
will be required to forward such information to the beneficial owners of the
Certificates. Generally, Holders must file tax returns that are consistent with
the information return filed by the Trust Fund or be subject to penalties unless
the Holder notifies the IRS of all such inconsistencies.
 
                                       73
<PAGE>   170
 
     Under Section 6031 of the Code, any person that holds Certificates as a
nominee at any time during a calendar year is required to furnish the Trust Fund
with a statement containing certain information on the nominee, the beneficial
owners and the Certificates so held. Such information includes (i) the name,
address and taxpayer identification number of the nominee and (ii) as to each
beneficial owner (a) the name, address and identification number of such person,
(b) whether such person is a United States person, a tax-exempt entity or a
foreign government, an international organization or any wholly owned agency or
instrumentality of either of the foregoing, and (c) certain information on
Certificates that were held, bought or sold on behalf of such person throughout
the year. In addition, brokers and financial institutions that hold Certificates
through a nominee are required to furnish directly to the Trust Fund information
as to themselves and their ownership of Certificates. A clearing agency
registered under Section 17A of the Exchange Act is not required to furnish any
such information statement to the Trust Fund. The information referred to above
for any calendar year must be furnished to the Trust Fund on or before the
following January 31. Nominees, brokers and financial institutions that fail to
provide the Trust Fund with the information described above may be subject to
penalties.
 
     The Depositor will be designated as the tax matters partner in the related
Trust Agreement and, as such, will be responsible for representing the
Certificateholders in any dispute with the IRS. The Code provides for
administrative examination of a partnership as if the partnership were a
separate and distinct taxpayer. Generally, the statute of limitations for
partnership items does not expire before three years after the date on which the
partnership information return is filed. Any adverse determination following an
audit of the return of the Trust Fund by the appropriate taxing authorities
could result in an adjustment of the returns of the Certificateholders, and,
under certain circumstances, a Certificateholder may be precluded from
separately litigating a proposed adjustment to the items of the Trust Fund. An
adjustment could also result in an audit of a Certificateholder's returns and
adjustments of items not related to the income and losses of the Trust Fund.
 
     Tax Consequences to Foreign Certificateholders.  It is not clear whether
the Trust Fund would be considered to be engaged in a trade or business in the
United States for purposes of federal withholding taxes with respect to non-U.S.
persons because there is no clear authority dealing with that issue under facts
substantially similar to those described herein. Although it is not expected
that the Trust Fund would be engaged in a trade or business in the United States
for such purposes, the Trust Fund will withhold as if it were so engaged in
order to protect the Trust Fund from possible adverse consequences of a failure
to withhold. The Trust Fund expects to withhold on the portion of its taxable
income that is allocable to foreign Certificateholders pursuant to Section 1446
of the Code, as if such income were effectively connected to a U.S. trade or
business, at a rate of 35% for foreign Holders that are taxable as corporations
and 39.6% for all other foreign Holders. Subsequent adoption of Treasury
regulations or the issuance of other administrative pronouncements may require
the Trust Fund to change its withholding procedures. In determining a Holder's
withholding status, the Trust Fund may rely on IRS Form W-8, IRS Form W-9 or the
Holder's certification of nonforeign status signed under penalties of perjury.
 
     Each foreign Holder might be required to file a U.S. individual or
corporate income tax return (including, in the case of a corporation, the branch
profits tax) on its share of the Trust Fund's income. Each foreign Holder must
obtain a taxpayer identification number from the IRS and submit that number to
the Trust Fund on Form W-8 in order to assure appropriate crediting of the taxes
withheld. A foreign Holder generally would be entitled to file with the IRS a
claim for refund with respect to taxes withheld by the Trust Fund taking the
position that no taxes were due because the Trust Fund was not engaged in a U.S.
trade or business. However, interest payments made (or accrued) to a
Certificateholder who is a foreign person generally will be considered
guaranteed payments to the extent such payments are determined without regard to
the income of the Trust Fund. If these interest payments are properly
characterized as guaranteed payments, then the interest will not be considered
"portfolio interest." As a result, Certificateholders will be subject to United
States federal income tax and withholding tax at a rate of 30 percent, unless
reduced or eliminated pursuant to an applicable treaty. In such case, a foreign
Holder would only be entitled to claim a refund for that portion of the taxes in
excess of the taxes that should be withheld with respect to the guaranteed
payments.
 
     Backup Withholding. Distributions made on the Certificates and proceeds
from the sale of the Certificates will be subject to a "backup" withholding tax
of 31% if, in general, the Certificateholder fails to
 
                                       74
<PAGE>   171
 
comply with certain identification procedures, unless the Holder is an exempt
recipient under applicable provisions of the Code. The New Regulations described
herein make certain modifications to the backup withholding and information
reporting rules. The New Regulations will generally be effective for payments
made after December 31, 1999, subject to certain transition rules. Prospective
investors are urged to consult their own tax advisors regarding the New
Regulations.
 
                            STATE TAX CONSIDERATIONS
 
     In addition to the federal income tax considerations described in "Certain
Federal Income Tax Considerations," potential investors should consider the
state and local income tax consequences of the acquisition, ownership, and
disposition of the Securities. State and local income tax law may differ
substantially from the corresponding federal law, and this discussion does not
purport to describe any aspect of the income tax laws of any state or locality.
Therefore, potential investors should consult their own tax advisors with
respect to the various state and local tax consequences of an investment in the
Securities.
 
                                FASIT SECURITIES
 
     General.  The FASIT provisions of the Code were enacted by the Small
Business Job Protection Act of 1996 and create a new elective statutory vehicle
for the issuance of mortgage-backed and asset-backed securities ("FASIT
Securities"). Although the FASIT provisions of the Code became effective on
September 1, 1997, no Treasury regulations or other administrative guidance has
been issued with respect to those provisions. Accordingly, definitive guidance
cannot be provided with respect to many aspects of the tax treatment of Holders
of FASIT Securities. Investors also should note that the FASIT discussions
contained herein constitutes only a summary of the federal income tax
consequences to Holders of FASIT Securities. With respect to each Series of
FASIT Securities, the related Prospectus Supplement will provide a detailed
discussion regarding the federal income tax consequences associated with the
particular transaction.
 
     FASIT Securities will be classified as either FASIT Regular Securities,
which generally will be treated as debt for federal income tax purposes, or
FASIT Ownership Securities, which generally are not treated as debt for such
purposes, but rather as representing rights and responsibilities with respect to
the taxable income or loss of the related Series. The Prospectus Supplement for
each Series of Securities will indicate whether one or more FASIT elections will
be made for such Series, and which Securities of such Series will be designated
as Regular Securities, and which, if any, will be designated as Ownership
Securities.
 
     Qualification as a FASIT.  The Trust Fund underlying a Series (or one or
more designated pools of assets held in the Trust Fund) will qualify under the
Code as a FASIT in which the FASIT Regular Securities and the FASIT Ownership
Securities will constitute the "regular interests" and the "ownership
interests," respectively, if (i) a FASIT election is in effect, (ii) certain
tests concerning (a) the composition of the FASIT's assets and (b) the nature of
the Holders' interest in the FASIT are met on a continuing basis and (iii) the
Trust Fund is not a regulated company as defined in Section 851(a) of the Code.
 
     Asset Composition.  In order for a Trust Fund (on one or more designated
pools of assets held by a Trust Fund) to be eligible for FASIT status,
substantially all of the assets of the Trust Fund (or the designated pool) must
consist of "permitted assets" as of the close of the third month beginning after
the Closing Date and at all times thereafter (the "FASIT Qualification Test").
Permitted assets include (i) cash or cash equivalents, (ii) debt instruments
with fixed terms that would qualify as REMIC regular interests if issued by a
REMIC (generally, instruments that provide for interest at a fixed rate, a
qualifying variable rate, or a qualifying interest-only ("IO") type rate, (iii)
foreclosure property, (iv) certain hedging instruments (generally, interest and
currency rate swaps and credit enhancement contracts) that are reasonably
required to guarantee or hedge against the FASIT's risks associated with being
the obligor on FASIT interests, (v) contract rights to acquire qualifying debt
instruments or qualifying hedging instruments, (vi) FASIT regular interests and
(vii) REMIC regular interests. Permitted assets do not include any debt
instruments issued by the Holder of the FASIT's ownership interest or by any
person related to such Holder.
 
     Interests in a FASIT.  In addition to the foregoing asset qualification
requirements, the interests in a FASIT also must meet certain requirements. All
of the interests in a FASIT must belong to either of the following: (i) one or
more Classes of regular interests or (ii) a single Class of ownership interest
that is held
                                       75
<PAGE>   172
 
by a fully taxable domestic corporation. In the case of Series that include
FASIT Ownership Securities, the ownership interest will be represented by the
FASIT Ownership Securities.
 
     A FASIT interest generally qualifies as a regular interest if (i) it is
designated as a regular interest, (ii) it has a stated maturity no greater than
thirty years, (iii) it entitles its Holder to a specified principal amount, (iv)
the issue price of the interest does not exceed 125% of its stated principal
amount, (v) the yield to maturity of the interest is less than the applicable
Treasury rate published by the IRS plus 5% and (vi) if it pays interest, such
interest is payable at either (a) a fixed rate with respect to the principal
amount of the regular interest or (b) a permissible variable rate with respect
to such principal amount. Permissible variable rates for FASIT regular interests
are the same as those for REMIC regular interest (i.e., certain qualified
floating rates and weighted average rates). See "Certain Federal Income Tax
Considerations -- Taxation of Debt Securities -- Variable Rate Debt Securities."
 
     If a FASIT Security fails to meet one or more of the requirements set out
in clauses (iii), (iv) or (v) above, but otherwise meets the above requirements,
it may still qualify as a type of regular interest known as a "High-Yield
Interest." In addition, if a FASIT Security fails to meet the requirements of
clause (vi), but the interest payable on the Security consists of a specified
portion of the interest payments on permitted assets and that portion does not
vary over the life of the Security, the Security also will qualify as a
High-Yield Interest. A High-Yield Interest may be held only by domestic
corporations that are fully subject to corporate income tax ("Eligible
Corporations"), other FASITs and dealers in securities who acquire such
interests as inventory, rather than for investment. In addition, Holders of
High-Yield Interests are subject to limitations on offset of income derived from
such interest. See "Certain Federal Income Tax Considerations -- FASIT
Securities -- Tax Treatment of FASIT Regular Securities -- Treatment of
High-Yield Interests."
 
     Consequences of Disqualification.  If a Series of FASIT Securities fails to
comply with one or more of the Code's ongoing requirements for FASIT status
during any taxable year, the Code provides that its FASIT status may be lost for
that year and thereafter. If FASIT status is lost, the treatment of the former
FASIT and the interests therein for federal income tax purposes is uncertain.
The former FASIT might be treated as a grantor trust, as a separate association
taxed as a corporation, or as a partnership. The FASIT Regular Securities could
be treated as debt instruments for federal income tax purposes or as equity
interests. Although the Code authorizes the Treasury to issue regulations that
address situations where a failure to meet the requirements for FASIT status
occurs inadvertently and in good faith, such regulations have not yet been
issued. It is possible that disqualification relief might be accompanied by
sanctions, such as the imposition of a corporate tax on all or a portion of the
FASIT's income for a period of time in which the requirements for FASIT status
are not satisfied.
 
     Tax Treatment of FASIT Regular Securities.  Payments received by Holders of
FASIT Regular Securities generally should be accorded the same tax treatment
under the Code as payments received on other taxable corporate debt instruments
and on REMIC Regular Securities. As in the case of Holders of REMIC Regular
Securities, Holders of FASIT Regular Securities must report income from such
Securities under an accrual method of accounting, even if they otherwise would
have used the case receipts and disbursements method. Except in the case of
FASIT Regular Securities issued with original issue discount or acquired with
market discount or premium, interest paid or accrued on a FASIT Regular Security
generally will be treated as ordinary income to the Holder and a principal
payment on such Security will be treated as a return of capital to the extent
that the Holder's basis is allocable to that payment. FASIT Regular Securities
issued with original issue discount or acquired with market discount or premium
generally will treat interest and principal payments on such Securities in the
same manner described for REMIC Regular Securities. See "Certain Federal Income
Tax Considerations -- Taxation of Debt Securities," " -- Market Discount," and
" -- Premium" above. High-Yield Securities may be held only by fully taxable
domestic corporations, other FASITs, and certain securities dealers. Holders of
High-Yield Securities are subject to limitations on their ability to use current
losses or net operating loss carryforwards or carrybacks to offset any income
derived from those Securities.
 
     If a FASIT Regular Security is sold or exchanged, the Holder generally will
recognize gain or loss upon the sale in the manner described above for REMIC
Regular Securities. See "Certain Federal Income Tax Considerations -- Sale or
Exchange." In addition, if a FASIT Regular Security becomes wholly or partially
 
                                       76
<PAGE>   173
 
worthless as a result of Default and Delinquencies of the underlying assets, the
Holder of such Security should be allowed to deduct the loss sustained (or
alternatively be able to report a lesser amount of income). See "Certain Federal
Income Tax Considerations -- Taxation of Debt Instruments -- Effects of Default
and Delinquencies."
 
     FASIT Regular Securities held by a REIT will qualify as "real estate
assets" within the meaning of section 856(c)(4)(A) of the Code, and interest on
such Securities will be considered Qualifying REIT Interest to the same extent
that REMIC Securities would be so considered. FASIT Regular Securities held by a
Thrift Institution taxed as a "domestic building and loan association" will
represent qualifying assets for purposes of the qualification requirements set
forth in Code Section 7701(a)(19) to the same extent that REMIC Securities would
be so considered. See "Certain Federal Income Tax Considerations -- Taxation of
Debt Securities -- Status as Real Property Loans." In addition, FASIT Regular
Securities held by a financial institution to which Section 585 of the Code
applies will be treated as evidences of indebtedness for purposes of Section
582(c)(1) of the Code. FASIT Securities will not qualify as "Government
Securities" for either REIT or RIC qualification purposes.
 
     Treatment of High-Yield Interests.  High-Yield Interests are subject to
special rules regarding the eligibility of Holders of such interests, and the
ability of such Holders to offset income derived from their FASIT Security with
losses. High-Yield Interests may be held only by Eligible Corporations other
FASITs, and dealers in securities who acquire such interests as inventory. If a
securities dealer (other than an Eligible Corporation) initially acquires a
High-Yield Interest as inventory, but later begins to hold it for investment,
the dealer will be subject to an excise tax equal to the income from the
High-Yield Interest multiplied by the highest corporate income tax rate. In
addition, transfers of High-Yield Interests to disqualified Holders will be
disregarded for federal income tax purposes, and the transferor still will be
treated as the Holder of the High-Yield Interest.
 
     The Holder of a High-Yield Interest may not use non-FASIT current losses or
net operating loss carryforwards or carrybacks to offset any income derived from
the High-Yield Interest, for either regular federal income tax purposes or for
alternative minimum tax purposes. In addition, the FASIT provisions contain an
anti-abuse rule that imposes corporate income tax on income derived from a FASIT
Regular Security that is held by a pass-through entity (other than another
FASIT) that issues debt or equity securities backed by the FASIT Regular
Security and that have the same features as High-Yield Interests.
 
     Tax Treatment of FASIT Ownership Securities. A FASIT Ownership Security
represents the residual equity interest in a FASIT. As such, the Holder of a
FASIT Ownership Security determines its taxable income by taking into account
all assets, liabilities and items of income, gain, deduction, loss and credit of
a FASIT. In general, the character of the income to the Holder of a FASIT
Ownership Interest will be the same as the character of such income of the
FASIT, except that any tax-exempt interest income taken into account by the
Holder of a FASIT Ownership Interest is treated as ordinary income. In
determining that taxable income, the Holder of a FASIT Ownership Security must
determine the amount of interest, original issue discount, market discount and
premium recognized with respect to the FASIT's assets and the FASIT Regular
Securities issued by the FASIT according to a constant yield methodology and
under an accrual method of accounting. In addition, Holders of FASIT Ownership
Securities are subject to the same limitations on their ability to use losses to
offset income from their FASIT Security as are the Holders of High-Yield
Interests. See "Certain Federal Income Tax Considerations -- Treatment of
High-Yield Interests."
 
     Rules similar to the wash sale rules applicable to REMIC Residual
Securities also will apply to FASIT Ownership Securities. Accordingly, losses on
dispositions of a FASIT Ownership Security generally will be disallowed where,
within six months before or after the disposition, the seller of such Security
acquires any other FASIT Ownership Security or, in the case of a FASIT holding
mortgage assets, any interest in a Taxable Mortgage Pool that is economically
comparable to a FASIT Ownership Security. In addition, if any security that is
sold or contributed to a FASIT by the Holder of the related FASIT Ownership
Security was required to be marked-to-market under Code section 475 by such
Holder, then section 475 will continue to apply to such securities, except that
the amount realized under the mark-to-market rules will be a greater of the
securities' value under present law or the securities' value after applying
special valuation rules contained
 
                                       77
<PAGE>   174
 
in the FASIT provisions. Those special valuation rules generally require that
the value of debt instruments that are not traded on an established securities
market be determined by calculating the present value of the reasonably expected
payments under the instrument using a discount rate of 120% of the applicable
federal rate, compounded semiannually.
 
     The Holder of a FASIT Ownership Security will be subject to a tax equal to
100% of the net income derived by the FASIT from any "prohibited transactions."
Prohibited transactions include (i) the receipt of income derived from assets
that are not permitted assets, (ii) certain dispositions of permitted assets,
(iii) the receipt of any income derived from any loan originated by a FASIT and
(iv) in certain cases, the receipt of income representing a servicing fee or
other compensation. Any Series for which a FASIT election is made generally will
be structured in order to avoid application of the prohibited transaction tax.
 
     Backup Withholding, Reporting and Tax Administration.  Holders of FASIT
Securities will be subject to backup withholding to the same extent Holders of
REMIC Securities would be subject. See "Certain Federal Income Tax
Considerations -- Miscellaneous Tax Aspects -- Backup Withholding." For purposes
of reporting and tax administration, Holders of record of FASIT Securities
generally will be treated in the same manner as Holders of REMIC Securities.
 
     DUE TO THE COMPLEXITY OF THE FEDERAL INCOME TAX RULES APPLICABLE TO HOLDERS
AND THE CONSIDERABLE UNCERTAINTY THAT EXISTS WITH RESPECT TO MANY ASPECTS OF
THOSE RULES, POTENTIAL INVESTORS SHOULD CONSULT THEIR OWN TAX ADVISORS REGARDING
THE TAX TREATMENT OF THE ACQUISITION, OWNERSHIP, AND DISPOSITION OF THE
SECURITIES.
 
                              ERISA CONSIDERATIONS
 
     The following describes certain considerations under ERISA and the Code,
which apply only to Securities of a Series that are not divided into subclasses.
If Securities are divided into subclasses, the related Prospectus Supplement
will contain information concerning considerations relating to ERISA and the
Code that are applicable to such Securities and such subclasses of Securities.
 
     ERISA imposes requirements on employee benefit plans (and on certain other
retirement plans and arrangements, including certain individual retirement
accounts and annuities, Keogh plans and collective investment funds and separate
accounts in which such plans, accounts or arrangements are invested)
(collectively "Plans") subject to ERISA and on persons who are fiduciaries with
respect to such Plans. Generally, ERISA applies to investments made by Plans.
Among other things, ERISA requires that the assets of Plans be held in trust and
that the trustee, or other duly authorized fiduciary, have exclusive authority
and discretion to manage and control the assets of such Plans. ERISA also
imposes certain duties on persons who are fiduciaries of Plans. Under ERISA, any
person who exercises any authority or control respecting the management or
disposition of the assets of a Plan is considered to be a fiduciary of such Plan
(subject to certain exceptions not here relevant). Certain employee benefit
plans, such as governmental plans (as defined in ERISA Section 3(32)) and, if no
election has been made under Section 410(d) of the Code, church plans (as
defined in ERISA Section 3(33)), are not subject to ERISA requirements.
Accordingly, assets of such plans may be invested in Securities without regard
to the ERISA considerations described above and below, subject to the provisions
of applicable state law. Any such plan that is qualified and exempt from
taxation under Code Sections 401(a) and 501(a), however, is subject to the
prohibited transaction rules set forth in Code Section 503.
 
     In addition to the imposition of general fiduciary standards of investment
prudence and diversification, ERISA and Section 4975 of the Code prohibit a
broad range of transactions involving Plan assets and persons ("Parties in
Interest") having certain specified relationships to a Plan and imposes
additional prohibitions where Parties in Interest are fiduciaries with respect
to such Plan. Certain Parties in Interest that participate in a prohibited
transaction may be subject to an excise tax imposed pursuant to Section 4975 of
the Code, or a penalty imposed pursuant to Section 502(i) of ERISA, unless a
statutory, regulatory or administrative exemption is available.
 
                                       78
<PAGE>   175
 
     On November 13, 1986, the United States Department of Labor (the "DOL")
issued final regulations (Labor Reg. Section 2510.3-101) concerning the
definition of what constitutes the assets of a Plan (the "Plan Asset
Regulation"). Under this regulation, the underlying assets and properties of
corporations, partnerships and certain other entities in which a Plan acquires
an "equity" interest could be deemed for purposes of ERISA to be assets of the
investing Plan in certain circumstances.
 
     Under the Plan Asset Regulation, the term "equity" interest is defined as
any interest in an entity other than an instrument that is treated as
indebtedness under "applicable local law" and which has no "substantial equity
features." If the Trust Fund issues Notes that are not treated as equity
interests in the Trust Fund for purposes of the Plan Asset Regulation, a Plan's
investment in such Notes would not cause the assets of the Trust to be deemed
Plan assets. However, the Seller, the Servicer, the Special Servicer, the Backup
Servicer, the Indenture Trustee, the Owner Trustee and the Depositor may be the
sponsor of or investment advisor with respect to one or more Plans. Because such
parties may receive certain benefits in connection with the sale of the Notes,
the purchase of Notes using Plan assets over which any such parties (or any
affiliates thereof) has investment authority might be deemed to be a violation
of the prohibited transaction rules of ERISA and the Code for which no exemption
may be available. Accordingly, Notes may not be purchased using the assets of
any Plan if the Seller, the Servicer, the Special Servicer, the Indenture
Trustee, the Owner Trustee, the Depositor or any of their affiliates (a) has
investment or administrative discretion with respect to such Plan assets; (b)
has authority or responsibility to give, or regularly gives, investment advice
with respect to such Plan assets for a fee and pursuant to an agreement of
understanding that such advice (i) will serve as a primary basis for investment
decisions with respect to such Plan assets and (ii) will be based on the
particular investment needs for such Plan; or (c) is an employer maintaining or
contributing to such Plan.
 
     In addition, the Trust Fund, any underwriter, trustee, servicer,
administrator or producer of credit support or their affiliates might be
considered or might become Parties in Interest with respect to a Plan. Also, any
holder of Notes, because of its activities or the activities of its respective
affiliates, may be deemed to be a Party in Interest with respect to certain
Plans, including but not limited to Plans sponsored by such holder. In either
case, the acquisition or holding of Notes by or on behalf of such a Plan could
be considered to give rise to an indirect prohibited transaction within the
meaning of ERISA and the Code, unless it is subject to one or more exemptions
such as: Prohibited Transaction Class Exemption ("PTCE") 84-14, which exempts
certain transactions effected on behalf of a Plan by a "qualified professional
asset manager"; PTCE 90-1, which exempts certain transactions involving
insurance company pooled separate accounts; PTCE 91-38, which exempts certain
transactions involving bank collective investment funds; PTCE 95-60, which
exempts certain transactions involving insurance company general accounts; or
PTCE 96-23, which exempts certain transactions effected on behalf of a Plan by
certain "in-house asset managers." There can be no assurance that any of these
class exemptions will apply with respect to any particular Plan investment in
Notes, or, even if it did apply, that any exemption would apply to all
prohibited transactions that may occur in connection with such an investment.
Each prospective purchaser or transferee of a Note that is a Plan or a person
acting on behalf or investing the assets of a Plan shall be required to
represent (or, with respect to any transfer of a beneficial interest in a Global
Note, shall be deemed to represent) to the Indenture Trustee and the Note
Registrar that the relevant conditions for exemptive relief under at least one
of the foregoing exemptions have been satisfied.
 
     The Plan Asset Regulation provides 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 the Plan Asset Regulation, is a security that is widely held,
freely transferable and registered under the Exchange Act.
 
     If no exception under the Plan Asset Regulation applies, then if a Plan (or
a person investing Plan assets, such as an insurance company general account)
acquires an equity interest in the Trust Fund, then the assets of the Trust Fund
would be considered to be assets of the Plan. Because the Loans held by the
Trust Fund may be deemed Plan assets of each Plan that purchases Securities, an
investment in the Securities by a Plan might be a prohibited transaction under
ERISA Sections 406 and 407 and subject to an excise tax under Code Section 4975
and may cause transactions undertaken in the course of operating the Trust Fund
to constitute prohibited transactions, unless a statutory or administrative
exemption applies.
 
                                       79
<PAGE>   176
 
     In Prohibited Transaction Class Exemption 83-1 ("PTCE 83-1"), which amended
Prohibited Transaction Class 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. PTCE 83-1 permits, subject to certain conditions, transactions
that 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 PTCE 83-1 are satisfied, investments by a Plan
in Securities that represent interests in a Pool consisting of Loans conforming
to these requirements ("Single Family Securities") 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 the Single Family Securities 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 Single Family
Securities, and at least 50% of all Single Family Securities are purchased by
persons independent of the pool sponsor or pool trustee. PTCE 83-1 does not
provide an exemption for transactions involving Subordinated Securities.
Accordingly, unless otherwise provided in the related Prospectus Supplement, no
transfer of a Subordinated Security or a Security that is not a Single Family
Security may be made to a Plan.
 
     The discussion in this and the next succeeding paragraph applies only to
Single Family Securities. The Depositor believes that, for purposes of PTCE
83-1, the term "mortgage pass-through certificate" would include: (i) Securities
issued in a Series consisting of only a single Class of Securities; and (ii)
Securities issued in a Series in which there is only one Class of those
particular Trust Securities; provided, that the Securities in the case of clause
(i), or the Securities in the case of clause (ii), evidence the beneficial
ownership of both a specified percentage of future interest payments (greater
than 0%) and a specified percentage (greater than 0%) of future principal
payments on the Loans. It is not clear whether a Class of Securities that
evidences the beneficial ownership in a Trust Fund divided into Loan groups,
beneficial ownership of a specified percentage of interest payments only or
principal payments only, or a notional amount of either principal or interest
payments, or a Class of Securities entitled to receive payments of interest and
principal on the Loans only after payments to other Classes or after the
occurrence of certain specified events would be a "mortgage pass-through
certificate" for purposes of PTCE 83-1.
 
     PTCE 83-1 sets forth three general conditions that 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 Holders 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 Pool. The Depositor believes that the first general condition referred to
above will be satisfied with respect to the Securities in a Series issued
without a subordination feature, or the unsubordinated Securities only in a
Series issued with a subordination feature; provided, that the subordination and
Reserve Account, subordination by shifting of interests, the pool insurance or
other form of credit enhancement described herein (such subordination, pool
insurance or other form of credit enhancement being the system of insurance or
other protection referred to above) with respect to a Series of Securities is
maintained in an amount not less than the greater of one percent of the
aggregate Principal Balance of the Loans or the Principal Balance of the largest
Loan. See "Description of the Securities" herein. In the absence of a ruling
that the system of insurance or other protection with respect to a Series of
Securities satisfies the first general condition referred to above, there can be
no assurance that these features will be so viewed by the DOL. The Trustee will
not be affiliated with the Depositor.
 
                                       80

     Each Plan fiduciary who is responsible for making the investment decisions
whether to purchase or commit to purchase and to hold Single Family Securities
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 PTCE 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 Securities is appropriate for the
Plan, taking into account the overall investment policy of the Plan and the
composition of the Plan's investment portfolio.
 
     The DOL issued to Bear, Stearns & Co.  Inc., an individual exemption
(Prohibited Transaction Exemption 90-30; Exemption Application No. D-8207, 55
Fed. Reg. 21461 (1990)) (the "Underwriter Exemption"), which applies to certain
sales and servicing of "certificates" that are obligations of a "trust" with
respect to which Bear, Stearns & Co. Inc. is the underwriter, manager or
co-manager of an underwriting syndicate. The Underwriter Exemption provides
relief generally similar to that provided by PTCE 83-1, but is broader in
several respects.
 
     The Underwriter Exemption contains several requirements, some of which
differ from those in PTCE 83-l. The Underwriter Exemption contains an expanded
definition of "certificate," which includes an interest that entitles the Holder
to pass-through payments of principal, interest and/or other payments. The
Underwriter Exemption contains an expanded definition of "trust," which permits
the trust corpus to consist of secured consumer receivables. The definition of
"trust," however, does not include any investment pool unless, inter alia, (i)
the investment pool consists only of assets of the type that have been included
in other investment pools, (ii) certificates evidencing interests in such other
investment pools have been purchased by investors other than Plans for at least
one year prior to the Plan's acquisition of certificates pursuant to the
Underwriter Exemption and (iii) certificates in such other investment pools have
been rated in one of the three highest generic rating categories of the four
credit rating agencies noted below. Generally, the Underwriter Exemption holds
that the acquisition of the certificates by a Plan must be on terms (including
the price for the certificates) that are at least as favorable to the Plan as
they would be in an arm's length transaction with an unrelated party. The
Underwriter Exemption requires that the rights and interests evidenced by the
certificates not be "subordinated" to the rights and interests evidenced by
other certificates of the same trust. The Underwriter Exemption requires that
certificates acquired by a Plan have received a rating at the time of their
acquisition that is in one of the three highest generic rating categories of
Standard & Poor's, a division of The McGraw-Hill Companies, Inc., Moody's
Investors Service, Inc., Duff & Phelps Credit Rating Co. or Fitch IBCA, Inc. The
Underwriter Exemption specifies that the pool trustee must not be an affiliate
of the pool sponsor, nor an affiliate of the Underwriter, the pool servicer, any
obligor with respect to mortgage loans included in the trust constituting more
than five percent of the aggregate unamortized principal balance of the assets
in the trust, or any affiliate of such entities. Finally, the Underwriter
Exemption stipulates that any Plan investing in the certificates must be an
"accredited investor" as defined in Rule 501(a)(1) of Regulation D of the
Commission under the Securities Act.
 
     On July 21, 1997, the DOL published in the Federal Register an amendment to
the Underwriter Exemption, which extends exemptive relief to certain
mortgage-backed and asset-backed securities transactions using pre-funding
accounts for trusts issuing pass-through certificates. The amendment generally
allows mortgage loans or other secured receivables (the "Obligations")
supporting payments to certificateholders, and having a value equal to no more
than twenty-five percent (25%) of the total principal amount of the certificates
being offered by the trust, to be transferred to the trust within a 90-day or
three-month period following the closing date (the "Specified Funding Period"),
instead of requiring that all such Obligations be either identified or
transferred on or before the Closing Date. The relief is available when the
following conditions are met:
 
          (1) The ratio of the amount allocated to the pre-funding account to
     the total principal amount of the certificates being offered (the
     "Specified Funding Limit") must not exceed twenty-five percent (25%).
 
          (2) All Obligations transferred after the Closing Date (the
     "Additional Obligations") must meet the same terms and conditions for
     eligibility as the original Obligations used to create the trust, which
     terms and conditions have been approved by an Exemption Rating Agency.
 
                                       81
<PAGE>   178
 
          (3) The transfer of such Additional Obligations to the trust during
     the Specified Funding Period must not result in the certificates to be
     covered by the Exemption receiving a lower credit rating from an Exemption
     Rating Agency upon termination of the Specified Funding Period than the
     rating that was obtained at the time of the initial issuance of the
     certificates by the trust.
 
          (4) Solely as a result of the use of pre-funding, the weighted average
     annual percentage interest rate for all of the Obligations in the trust at
     the end of the Specified Funding Period must not be more than 100 basis
     points lower than the average interest rate for the Obligations transferred
     to the trust on the Closing Date.
 
          (5) In order to insure that the characteristics of the Additional
     Obligations are substantially similar to the original Obligations which
     were transferred to the Trust Fund:
 
             (i) the characteristics of the Additional Obligations must be
        monitored by an insurer or other credit support provider that is
        independent of the depositor; or
 
             (ii) an independent accountant retained by the depositor must
        provide the depositor with a letter (with copies provided to each
        Exemption Rating Agency rating the certificates, the related underwriter
        and the related trustee) stating whether or not the characteristics of
        the Additional Obligations conform to the characteristics described in
        the related prospectus or prospectus supplement and/or pooling and
        servicing agreement. In preparing such letter, the independent
        accountant must use the same type of procedures as were applicable to
        the Obligations transferred to the trust as of the Closing Date.
 
          (6) The period of pre-funding must end no later than three months or
     90 days after the Closing Date or earlier in certain circumstances if the
     pre-funding account falls below the minimum level specified in the pooling
     and servicing agreement or an Event of Default occurs.
 
          (7) Amounts transferred to any pre-funding account and/or capitalized
     interest account used in connection with the pre-funding may be invested
     only in certain permitted investments ("Permitted Investments").
 
          (8) The related prospectus or prospectus supplement must describe:
 
             (i) any pre-funding account and/or capitalized interest account
        used in connection with a pre-funding account;
 
             (ii) the duration of the period of pre-funding;
 
             (iii) the percentage and/or dollar amount of the Specified Funding
        Limit for the trust; and
 
             (iv) that the amounts remaining in the pre-funding account at the
        end of the Specified Funding Period will be remitted to
        certificateholders as repayments of principal.
 
          (9) The related pooling and servicing agreement must describe the
     Permitted Investments for the pre-funding account and/or capitalized
     interest account and, if not disclosed in the related prospectus or
     prospectus supplement, the terms and conditions for eligibility of
     Additional Obligations.
 
     Neither PTCE 83-1 nor the Underwriter Exemption applies to a trust which
contains unsecured obligations.
 
     Any Plan fiduciary that proposes to cause a Plan to purchase Securities
should consult with their counsel concerning the impact of ERISA and the Code,
the applicability of PTCE 83-1 and the Underwriter Exemption, 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 Securities is appropriate for the Plan, taking into account the overall
investment policy of the Plan and the composition of the Plan's investment
portfolio.
 
                                 LEGAL MATTERS
 
     The legality of the Securities of each Series, including certain material
federal income tax consequences with respect thereto, will be passed upon for
the Depositor by Brown & Wood LLP, One World Trade Center, New York, New York
10048.

                             FINANCIAL INFORMATION
 
     A new Trust Fund will be formed with respect to each Series of Securities,
and no Trust Fund will engage in any business activities or have any assets or
obligations prior to the issuance of the related Series of Securities.
Accordingly, no financial statements with respect to any Trust Fund will be
included in this Prospectus or in the related Prospectus Supplement.
 
                                     RATING
 
     It is a condition to the issuance of the Securities of each Series offered
hereby and by the Prospectus Supplement that they shall have been rated in one
of the four highest rating categories by the nationally recognized statistical
rating agency or agencies (each, a "Rating Agency") specified in the related
Prospectus Supplement.
 
     Any such rating would be based on, among other things, the adequacy of the
value of the Trust Fund assets and any credit enhancement with respect to the
related Class and will reflect such Rating Agency's assessment solely of the
likelihood that the related Holders will receive payments to which such Holders
are entitled under the related Agreement. Such rating will not constitute an
assessment of the likelihood that principal prepayments on the related Loans
will be made, the degree to which the rate of such prepayments might differ from
that originally anticipated or the likelihood of early optional termination of
the Series of Securities. Such rating should not be deemed a recommendation to
purchase, hold or sell Securities, inasmuch as it does not address market price
or suitability for a particular investor. Such rating will not address the
possibility that prepayment at higher or lower rates than anticipated by an
investor may cause such investor to experience a lower than anticipated yield or
that an investor purchasing a Security at a significant premium might fail to
recoup its initial investment under certain prepayment scenarios.
 
     There is also no assurance that any such rating will remain in effect for
any given period of time or that it may not be lowered or withdrawn entirely by
the Rating Agencies in the future if in their judgment circumstances so warrant.
In addition to being lowered or withdrawn due to any erosion in the adequacy of
the value of the Trust Fund assets or any credit enhancement with respect to a
Series, such rating might also be lowered or withdrawn because of, among other
reasons, an adverse change in the financial or other condition of a credit
enhancement provider or a change in the rating of such credit enhancement
provider's long term debt.
 
     The amount, type and nature of credit enhancement, if any, established with
respect to a Series of Securities will be determined on the basis of criteria
established by each Rating Agency rating Classes of such Series. Such criteria
are sometimes based upon an actuarial analysis of the behavior of mortgage loans
in a larger group. Such analysis is often the basis upon which each Rating
Agency determines the amount of credit enhancement required with respect to each
such Class. There can be no assurance that the historical data supporting any
such actuarial analysis will accurately reflect future experience nor any
assurance that the data derived from a large pool of mortgage loans accurately
predicts the delinquency, foreclosure or loss experience of any particular pool
of Loans. No assurance can be given that values of any Properties have remained
or will remain at their levels on the respective dates of origination of the
related Loans. If the residential real estate markets should experience an
overall decline in property values such that the Principal Balances of the Loans
in a particular Trust Fund and any secondary financing on the related Properties
become equal to or greater than the value of such Properties, the rates of
delinquencies, foreclosures and losses could be higher than those now generally
experienced in the mortgage lending industry. In additional, adverse economic
conditions (which may or may not affect real property values) may affect the
timely payment by mortgagors of scheduled payments of principal of and interest
on the Loans and, accordingly, the rates of delinquencies, foreclosures and
losses with respect to any Trust Fund. To the extent that such losses are not
covered by credit enhancement, such losses will be borne, at least in part, by
the Holders of one or more Classes of the Securities of the related Series.
 
                                LEGAL INVESTMENT
 
     Unless otherwise specified in the related Prospectus Supplement, the
Securities will not constitute "mortgage-related securities" within the meaning
of SMMEA. Accordingly, investors whose investment
 
                                       83
<PAGE>   180
 
authority is subject to legal restrictions should consult their own legal
advisors to determine whether and to what extent the Securities constitute legal
investments for them.
 
                              PLAN OF DISTRIBUTION
 
     The Depositor may offer each Series of Securities through Bear, Stearns &
Co. Inc. ("Bear Stearns") or one or more other firms that may be designated at
the time of each offering of such Securities. The participation of Bear Stearns
in any offering will comply with Schedule E to the By-Laws of the National
Association of Securities Dealers, Inc. The Prospectus Supplement relating to
each Series of Securities will set forth the specific terms of the offering of
such Series of Securities and of each Class within such Series, the names of the
underwriters, the purchase price of the Securities, the proceeds to the
Depositor from such sale, any securities exchange on which the Securities may be

and commissions to the underwriters and any discounts and concessions allowed or
reallowed to certain dealers. The place and time of delivery of each Series of
Securities will also be set forth in the Prospectus Supplement relating to such
