                                  (5) On each Payment Date, the Class B-1A
                                  Pass-Through Rate will be equal to the lesser

                                  Since, however, the margin over LIBOR is
                                  different for each Class of the Adjustable
                                  Rate Group Certificates, it is possible that,

                                  Mortgage Loans acquired by the Sponsor through

                                  information presented herein is based on the
                                  number and the principal balances of such
                                  Mortgage Loans as of the Cut-Off Date.  The

                                  $205,000,731.13.  The Sponsor expects that the
                                  actual pools as of the Closing Date will
                                  represent approximately $340,000,000 in
                                  Mortgage Loans in the Fixed Rate Group and
                                  approximately $210,000,000 in Mortgage Loans
                                  in the Adjustable Rate Group.  The additional

                                  pools will represent Mortgage Loans acquired
                                  or to be acquired by the Sponsor prior to the
                                  Closing Date.  In addition, with respect to
                                  the Statistic Calculation Pools as to which
                                  statistical information is presented herein,

                                  the Statistic Calculation Pools may prepay in
                                  full or may be determined not to meet the

                                  characteristics as of the Closing Date in the
                                  final Mortgage Loan pools will vary somewhat
                                  from the statistical distribution of such
                                  characteristics in the Statistic Calculation

                                  the Sponsor does not expect that the original
                                  principal amount of any class will increase or
                                  decrease by more than 5% as a result of such
                                  non- delivery.  Even if the full expected
                                  amount of Mortgage Loans is delivered, certain
                                  adjustments (plus or minus 5%) may occur
                                  between the class sizes.

                                  Unless otherwise noted, all statistical

                                  equity loans, i.e., loans used (x) to

                                  to zero, all amounts of principal that would
                                  have been distributed on such Class M- 2
                                  Certificates will be distributed to the

                                  Application of Realized Losses. The Pooling
                                  and Servicing Agreement provides that if a
                                  Mortgage Loan becomes a Liquidated Loan during
                                  a Remittance Period, the Net Liquidation
                                  Proceeds relating thereto and allocated to
                                  principal may be less than the Principal
                                  Balance of such Mortgage Loan. The amount of
                                  such insufficiency is a "Realized Loss".
                                  Realized Losses which occur in a Mortgage Loan
                                  Group will, in effect, be absorbed first, by

                                  Interest Amount to fund such deficiency and
                                  through a reduction in the related
                                  Overcollateralization Amount), second, by the
                                  Owners of the related Class B Certificates,
                                  third, by the Owners of the

                                  related Class M-2 Certificates, and, fourth,
                                  by the Owners of the related Class M-1
                                  Certificates.

                                  To the extent that a Mortgage Loan Group
                                  experiences Realized Losses, such Realized
                                  Losses will reduce the aggregate outstanding
                                  Principal Balance of the Mortgage Loans in
                                  such Mortgage Loan Group (i.e., a reduction in
                                  the collateral balance will occur). Since the
                                  Overcollateralization Amount with respect to a
                                  Mortgage Loan Group is the excess, if any, of
                                  the related collateral balance over the
                                  related Aggregate Certificate Principal
                                  Balance, Realized Losses, to the extent
                                  experienced, will in the first instance reduce
                                  the related Overcollateralization Amount.

                                  The Pooling and Servicing Agreement requires
                                  that the Overcollateralization Amount with
                                  respect to a Mortgage Loan Group be initially
                                  increased to, and thereafter maintained at,
                                  the related Targeted Overcollateralization
                                  Amount. This increase and subsequent
                                  maintenance is intended to be accomplished by
                                  the application of related Monthly Excess
                                  Interest Amounts to the funding of the related
                                  Extra Principal Distribution Amount. Such
                                  Extra Principal Distribution Amounts, since
                                  they are funded from interest collections on
                                  the collateral but are distributed as
                                  principal on the Offered Certificates, will
                                  increase the related Overcollateralization
                                  Amount.

                                  If, on any Payment Date after taking into
                                  account all Realized Losses experienced during
                                  the prior Remittance Period and after taking
                                  into account the distribution of principal
                                  (including the Extra Principal Distribution
                                  Amount) with respect to the related Offered
                                  Certificates on such Payment Date, the
                                  Aggregate Certificate Principal Balance with

                                  respect to a Mortgage Loan Group exceeds the
                                  aggregate Principal Balance of the Mortgage
                                  Loans in such Mortgage Loan Group as of the
                                  end of the related Remittance Period (i.e., if
                                  the level of overcollateralization is
                                  negative), then the Certificate Principal
                                  Balance of the related Subordinate
                                  Certificates will be reduced (in effect,
                                  "written down") such that the level of
                                  overcollateralization is zero, rather than
                                  negative. Such a negative level of
                                  overcollateralization is an "Applied Realized
                                  Loss Amount", which will be applied as a
                                  reduction in the Certificate Principal Balance
                                  of the related Subordinate Certificates in

                                  reduced to zero). The Pooling and Servicing
                                  Agreement does not permit the "write down" of
                                  the Certificate Principal Balance of any Class
                                  A Certificate.

                                  "written down," the amount of such write down
                                  will no longer bear interest, nor will such
                                  amount thereafter be "reinstated" or "written
                                  up," although the amount of such write down
                                  may, on future Payment Dates be paid to Owners
                                  of the Subordinate Certificates which
                                  experienced the write down, in direct order of
                                  seniority (i.e., first, the Class M-1
                                  Certificates, second, the Class M-2
                                  Certificates and, third, the Class B
                                  Certificates). The source of funding of such
                                  payments will be the amount, if any, of the
                                  Monthly Excess Cashflow Amount remaining on
                                  such future Payment Dates after the funding of
                                  the Extra Principal Distribution Amount and
                                  after the payment of Interest Carry Forward
                                  Amounts with respect to the related
                                  Subordinate Certificates on such Payment Date.

                                  Application of Monthly Excess Cashflow

                                  Amounts. The weighted average net Coupon Rate
                                  for the Mortgage Loans in each Mortgage Loan
                                  Group is generally expected to be higher than
                                  the weighted average of the Pass-Through Rates
                                  on the Offered Certificates related to such
                                  Mortgage Loan Group, thus generating certain
                                  excess interest collections which, in the
                                  absence of losses will not be necessary to
                                  fund interest distributions on the Offered
                                  Certificates. The Pooling and Servicing
                                  Agreement provides that this excess interest
                                  be applied to the extent available, to make
                                  accelerated payments of principal (i.e., the
                                  Extra Principal Distribution Amount) to the
                                  Class or Classes then entitled to receive
                                  distributions of principal; such application
                                  will cause the Aggregate Certificate Balance
                                  with respect to a Mortgage Loan Group to
                                  amortize more rapidly than the Mortgage Loans
                                  in such Mortgage Loan Group, resulting in
                                  Overcollateralization. This excess interest
                                  for a Remittance Period and with respect to a
                                  Mortgage Loan Group, together with interest on
                                  the related Overcollateralization Amount
                                  itself, on the related Payment Date is the
                                  "Monthly Excess Interest Amount" for such
                                  Payment Date and Mortgage Loan Group.

                                  The required level of overcollateralization
                                  for any Mortgage Loan Group and Payment Date
                                  is the Targeted Overcollateralization Amount

                                  Closing Date less than the related Targeted
                                  Overcollateralization Amount, in the early
                                  months of the transaction, subject to the
                                  availability of Monthly Excess Interest
                                  Amounts, Extra Principal Distribution Amounts
                                  will be paid, with the result that the
                                  Overcollateralization Amount with respect to
                                  each Mortgage Loan Group will increase to the

                                  level of the related Targeted
                                  Overcollateralization Amount.

                                  If, once the Targeted Overcollateralization

                                  Group has been reached, Realized Losses occur
                                  in such Mortgage Loan Group, such Realized
                                  Losses will result in an Overcollateralization
                                  Deficiency (since such Realized Losses reduce
                                  the Principal Balance of the related Mortgage
                                  Loans without giving rise to a corresponding
                                  reduction of the related Aggregate Certificate
                                  Principal Balance). The cashflow priorities of
                                  the Trust require that, in this situation, an
                                  Extra Principal Distribution Amount be paid
                                  (subject to the availability of any Monthly
                                  Excess Interest Amount) for the purpose of

                                  On and after the Stepdown Date, the Targeted
                                  Overcollateralization Amount with respect to
                                  the Fixed Rate Group and the Adjustable Rate

                                  Principal Balance of the related Mortgage Loan

                                  Adjustable Rate Group). If the Targeted

                                  each Mortgage Loan Group is permitted to
                                  "stepdown" on a Payment Date, the Pooling and
                                  Servicing Agreement permits a portion of the
                                  related Principal Remittance Amount for such
                                  Payment Date not to be passed through as a

                                  Date. This has the effect of decelerating the
                                  amortization of the Offered Certificates with
                                  respect to each Mortgage Loan Group relative

                                  future collections on the Mortgage Loan which
                                  gave rise to the Delinquency Advance, (ii)
                                  Liquidation Proceeds for such Mortgage Loan
                                  and (iii) from certain excess cash flows not
                                  applied to any other purpose.  "Delinquency
                                  Advances" are amounts deposited in the
                                  Principal and Interest Account by the Master
                                  Servicer equal to the sum of the interest
                                  portions (net of the Servicing Fees and
                                  certain other administrative amounts, if any)
                                  due, but not collected with respect to
                                  delinquent Mortgage Loans during the related
                                  Remittance Period.  No Delinquency Advance
                                  will be required to be made by the Master
                                  Servicer if, in the good faith judgment of the
                                  Master Servicer, such Delinquency Advance
                                  would not ultimately be recoverable from the
                                  related Mortgage Loan (any such advance, a
                                  "Nonrecoverable Delinquency Advance"); and if
                                  previously made by the Master Servicer, a
                                  Nonrecoverable Delinquency Advance will be
                                  reimbursable from any amounts in the Principal
                                  and Interest Account prior to any

                                  distributions being made to

                                  The Master Servicer will also be obligated to
                                  make advances with respect to certain taxes
                                  and insurance premiums not paid by Mortgages
                                  on a timely basis. No Servicing Advance will
                                  be required to be made by Master Servicer, if
                                  in the good faith judgment or the Master
                                  Servicer, such

                                  Servicing Advance would not ultimately be
                                  recoverable from the related Mortgage Loan
                                  (any such advance, a "Nonrecoverable Servicing
                                  Advance"); and if previously made by the
                                  Master Servicer, a Nonrecoverable Servicing
                                  Advance will be reimbursable from any amounts
                                  in the Principal and Interest Account prior to

                                  In addition, the Master Servicer will also be
                                  required to deposit Compensating Interest in
                                  the Principal and Interest Account with
                                  respect to any full Prepayment received on a
                                  Mortgage Loan during the related Remittance
                                  Period out of its own funds without any right
                                  of reimbursement therefor. "Compensating
                                  Interest" is an amount equal to the difference
                                  between (x) 30 days' interest at the Mortgage
                                  Loan's coupon rate on the principal balance as
                                  of the first day of the related Remittance
                                  Period and (y) to the extent not previously
                                  advanced, the interest paid by the Mortgagor
                                  with respect to the Mortgage Loan. The Master
                                  Servicer will not be required to pay
                                  Compensating Interest with respect to any
                                  Remittance Period in an amount in excess of
                                  the aggregate Servicing Fee received by the
                                  Master Servicer for such Remittance Period.

Servicing Fee                     Advanta Mortgage Corp. USA will retain a 
                                  Servicing Fee equal to 0.50% per annum.

Optional Termination              The Master Servicer, acting directly or 
                                  through a permitted designee, will have the
                                  right to purchase from the Trust all the
                                  Mortgage Loans then held by the Trust at a

                                  price at least equal to par plus accrued

                                  amounts owed to the Master Servicer, on any
                                  Remittance Date after the Remittance Period
                                  during which the outstanding aggregate

                                  Loans as of the Closing Date.  The first such

                                  The ratings do not address the likelihood of
                                  the payment of Supplemental Interest Amounts.

Federal Tax Aspects               For federal income tax purposes, an election 
                                  will be made to treat certain assets of the
                                  Trust as one or more REMICs. Each of the Fixed
                                  Rate Group Certificates will be a "regular
                                  interest" in a REMIC which will be treated as
                                  a debt instrument of the Trust for federal
                                  income tax purposes.  The Adjustable Rate
                                  Certificates will be comprised of a "regular"
                                  interest in a REMIC and of the right to
                                  receive Supplemental Interest Payments, which
                                  right has the tax characteristics described

                                  herein.  A class of Class R Certificates will
                                  be designated as the "residual interest" with
                                  respect to each REMIC election made by the
                                  Trust.  See "Certain Federal Income Tax
                                  Consequences" herein and in the Prospectus.

ERISA Considerations              As described under "ERISA Considerations" 
                                  herein, the Class A Certificates may be
                                  purchased by employee benefit plans that are
                                  subject to ERISA.  The Subordinate
                                  Certificates may not be purchased by employee
                                  benefit plans that are subject to ERISA except
                                  as provided herein.  See "ERISA
                                  Considerations" herein and in the Prospectus.

Legal Investment
Considerations                    The Offered Certificates will not constitute 
                                  "mortgage related securities" for purposes of
                                  the Secondary Mortgage Market Enhancement Act
                                  of 1984 ("SMMEA").  In addition, institutions
                                  whose activities are subject to review by
                                  federal or state regulatory authorities may be
                                  or may become subject to restrictions, which

                                 RISK FACTORS

         Prospective investors in the Offered Certificates should consider the
following factors, as well as the factors set forth under "Risk Factors" in the
Prospectus, in connection with the purchase of the Offered Certificates.

         Risk of Higher Default Rates for Mortgage Loans with Balloon Payments.
18.98% of the Mortgage Loans in the Statistic Calculation Pools by aggregate
principal balance are Balloon Loans.  See "Risk Factors -- Risk of Losses 
Associated with Balloon Loans" in the Prospectus.

         Subordination--Limited Protection Afforded to Class A Certificates. The
rights of the Owners of the Class M-1 Certificates to receive distributions with
respect to the Mortgage Loans will be subordinate to the rights of the holders
of the Class A Certificates to receive such distributions, the rights of Owners
of the Class M-2 Certificates to receive distributions with respect to the
Mortgage Loans will be subordinate to the rights of the Owners of the Class A
and the Class M-1 Certificates to receive such distributions and the rights of
the Owners of the Class B Certificates to receive distributions with respect to
the Mortgage Loans will be subordinate to the rights of the Owners of the Class
A, Class M-1 and Class M-2 Certificates to receive such distributions. The
subordination of the Subordinate Certificates relative to the Class A
Certificates (and of the more lower-ranking Classes of the Subordinate
Certificates to the less higher-ranking Classes thereof) is intended to enhance
the likelihood of regular receipt by the Owners of the Class A Certificates (and
such higher-ranking Classes) of the full amount of the monthly distributions
allocable to them, and to afford such Owners protection against losses.

         Subordination--Allocation of Losses to Subordinate Certificates. The
rights of the Owners of each Class of Subordinate Certificates to receive
distributions of principal with respect to the Mortgage Loans will be
subordinate to the rights of the Owners of the Class A Certificates to receive
such distributions and to the rights of the Owners of each higher-ranking Class
of Subordinate Certificates to receive such distributions. See "Credit
Enhancement--Subordination of Subordinate Certificates" herein.

         The yields to maturity on the Mezzanine Certificates and Class B
Certificates will be sensitive, in varying degrees, to defaults on the Mortgage
Loans (and the timing thereof). Investors should fully consider the risks
associated with an investment in the Mezzanine Certificates or Class B
Certificates, including the possibility that such investors may not fully
recover their initial investment as a result of Realized Losses on the Mortgage
Loans. See "Credit Enhancement--Application of Realized Losses" and "Prepayment
and Yield Considerations--Projected Payment and Yield for Offered Certificates"
herein.

         Nature of Security. Since the Mortgage Loans are secured in certain
cases by junior liens subordinate to the rights of the mortgagee or beneficiary
under the related senior mortgage(s) or deed(s) of trust, the proceeds from any
liquidation, insurance or condemnation proceedings will be available to satisfy
the outstanding balance of such a junior Mortgage Loan only to the extent that
the claims of such senior mortgagee(s) or beneficiary(ies) 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 mortgage(s), in which case it must either pay
the entire amount due on the senior mortgage(s) to the senior mortgagee(s) at or
prior to the foreclosure sale or undertake the obligation to make payments on
the senior mortgage(s) in the event the mortgagor is in default thereunder. In
servicing junior mortgages in its portfolio, it is generally the Master
Servicer's practice to satisfy the senior mortgage(s) at or prior to the
foreclosure sale. The Master Servicer may also advance funds to keep the senior
mortgage(s) current until such time as the Master Servicer satisfies the senior
mortgage(s). The Trust will have no source of funds (and may not be permitted
under the REMIC provisions of the Code) to satisfy the 

                                     S-31

<PAGE>

senior mortgage(s) or make payments due to the senior mortgagee(s). The Master
Servicer will be required to advance such amounts in accordance with the Pooling
and Servicing Agreement.

         Information is provided under "The Mortgage Loan Pool -- General" with
respect to the LTVs and the CLTVs of the Mortgage Loans in the Statistic
Calculation Pools. As discussed in the Prospectus under "Risk Factors," the
value of the Mortgaged Properties underlying such loans could be adversely
affected by a number of factors. As a result, despite the amortization of the
junior and senior mortgage loans on such Mortgaged Properties, there can be no
assurance that the CLTVs of such loans, determined as of a date subsequent to
the origination date, will be the same or lower than the CLTVs for such loans,
determined as of the origination date.

         Even assuming that the Mortgaged Properties provided adequate security
for the Mortgage Loans, substantial delay could be encountered in connection
with the liquidation of defaulted Mortgage Loans and corresponding delays in the
receipt of such proceeds by the Trust could occur. Further, the Master Servicer
will be entitled to deduct from liquidation proceeds received in respect of a
fully liquidated Mortgage Loan all expenses incurred in attempting to recover
amounts due on such Mortgage Loan and not yet repaid, including payments to
senior mortgagees, legal fees, real estate taxes, and maintenance and
preservation expenses, thereby reducing collections available to the Trust.

         Liquidation expenses with respect to defaulted Mortgage Loans do not
vary directly with the outstanding principal balance of the loan at the time of
default. Therefore, assuming that a servicer took the same steps in realizing
upon a defaulted mortgage loan having a small remaining principal balance as it
would in the case of a defaulted mortgage loan having a larger principal
balance, the amount realized after expenses of liquidation would be smaller as a
percentage of the outstanding principal balance of the smaller mortgage loan
than would be the case with a larger loan. Because the average outstanding
principal balances of the Mortgage Loans are small relative to the size of the
loans in a typical pool of purchase-money first mortgages, realizations net of
liquidation expenses on defaulted Mortgage Loans may also be smaller as a
percentage of the principal amount of the Mortgage Loans than would such net
realizations in the case of a typical pool of purchase-money first mortgage

loans.

         Investor-owned properties represent (based solely upon statements made
by the borrowers at the time of origination of the related Mortgage Loan), as a
percentage of the aggregate principal balance of the Mortgage Loans in the
Statistic Calculation Pools, 5.97% of the Mortgage Loans. It is possible that
the rate of delinquencies, foreclosures and losses on mortgage loans secured by
non-owner occupied properties could be higher than for loans secured by the
primary residence of the borrower.

         Risk of Mortgage Loan Rates Reducing the Pass-Through Rate on the
Adjustable Rate Group Certificates. The calculation of the Pass-Through Rate on
the Adjustable Rate Group Certificates is based upon (i) the value of an index
(LIBOR) which is different from the value of the index applicable to the
Mortgage Loans in the Adjustable Rate Group as described under "The Mortgage
Loan Pool -- Mortgage Loans -Adjustable Rate Group" (either as a result of the
use of a different index, rate determination date or rate adjustment date) and
(ii) the weighted average of the Coupon Rates of the Mortgage Loans in the
Adjustable Rate Group which are subject to periodic adjustment caps, maximum
rate caps and minimum rate floors. 82.44% of the Mortgage Loans in the
Adjustable Rate Group by aggregate Principal Balance as of the Cut-Off Date
adjust semi-annually based upon the London interbank offered rate for six-month
United States dollar deposits ("Six-Month LIBOR") and 17.35% adjust annually
based upon the one-year constant maturity treasury (the "CMT"), whereas the
Pass-Through Rate on the Adjustable Rate Group Certificates adjusts monthly
based upon LIBOR as described under "Description of the Offered Certificates --
Calculation of LIBOR" herein, subject to the Adjustable Rate Group Available
Funds Cap (unless Supplemental Interest Amounts, the payment of which is not
rated, are paid in full). Consequently, the interest which becomes due 

                                     S-32

<PAGE>

on the Mortgage Loans in the Adjustable Rate Group (net of the Servicing Fee,
the Trustee Fee, and certain required reductions) during any Remittance Period
may not equal the amount of interest that would accrue at LIBOR plus the margin
on the Adjustable Rate Group Certificates during the related Accrual Period.
34.60% of the Mortgage Loans in the Adjustable Rate Group by aggregate Principal
Balance as of the Cut-Off Date are 2/28 Loans that provide for a fixed interest
rate for a period of approximately two years following origination. 14.20% of
the Mortgage Loans in the Adjustable Rate Group by aggregate Principal Balance
as of the Cut-Off Date are 3/27 Loans that provide for a fixed interest rate for
a period of approximately three years following origination. 18.96% of the
Mortgage Loans in the Adjustable Rate Group by aggregate Principal Balance as of
the Cut-Off Date are 5/25 Loans that provide for a fixed interest rate for a
period of approximately five years following origination. Thereafter, such
Mortgage Loans provide for interest rate and payment adjustments in a manner
similar to the Six-Month LIBOR Loans and one-year CMT Loans. In particular, the
Pass-Through Rate on the Adjustable Rate Group Certificates adjusts monthly,
while the interest rates of the Mortgage Loans in the Adjustable Rate Group
adjust less frequently with the result that the Adjustable Rate Group Available
Funds Cap may limit increases in the Pass-Through Rate on the Adjustable Rate
Group Certificates for extended periods in a rising interest rate environment.

In addition, LIBOR, Six-Month LIBOR and one-year CMT may respond to different
economic and market factors, and there is not necessarily a correlation between
them. Thus, it is possible, for example, that LIBOR may rise during periods in
which Six-Month LIBOR or one-year CMT is stable or is falling or that, even if
LIBOR, Six-Month LIBOR and one-year CMT rise during the same period, LIBOR may
rise more rapidly than Six-Month LIBOR or the one-year CMT. Furthermore, if the
Adjustable Rate Group Available Funds Cap determines the Pass-Through Rate on
the Adjustable Rate Group Certificates for a Payment Date, the value of the
Adjustable Rate Group Certificates will be temporarily or permanently reduced.

                       THE PORTFOLIO OF MORTGAGE LOANS

         The Mortgage Loan Pool includes loans which were either originated
directly by the Affiliated Originators or purchased by the Affiliated
Originators from others on a loan-by-loan basis and in either case acquired by
the Sponsor. The Sponsor also acquires loans from Unaffiliated Originators in
acquisitions from Conduit Participants or in bulk acquisitions of loan
portfolios. Such loans are originated by Unaffiliated Originators either
directly or purchased by the Unaffiliated Originators from others on a
loan-by-loan basis.

         The Originators which are affiliated with the Sponsor are Advanta 
Mortgage Corp. USA, Advanta National Bank USA, Advanta Mortgage Corp.
Midatlantic, Advanta Mortgage Corp. Midatlantic II, Advanta Mortgage Corp.
Midwest, Advanta Mortgage Corp. of New Jersey, Advanta Mortgage Corp. Northeast
and Advanta Finance Corp.

Unaffiliated Originators

         MCA. The Sponsor acquired approximately 10.82% of the Mortgage Loans in
the Statistic Calculation Pools from Mortgage Corporation of America, an
Unaffiliated Originator (such mortgage loans, the "MCA Loans"). Mortgage
Corporation of America is headquartered in Southfield, Michigan and is engaged
in originating mortgage loans through retail and wholesale channels. The MCA
Loans consist of 910 Mortgages representing an aggregate principal balance of
$56,266,463.77 as of the Cut-Off Date. Approximately 76.44% (by aggregate
principal balance as of the Cut-Off Date) of the MCA Loans are included in the
Fixed Rate Group and approximately 23.56% of the MCA Loans are included in the
Adjustable Rate Group. The MCA Loans are related to properties located in 13
states.

         Prior to its purchase of the MCA Loans, the Sponsor performed or caused
to be performed an operational review of the origination and servicing practices
of MCA.

                                     S-33

<PAGE>

         The weighted average CLTV of the MCA Loans in the Statistic Calculation
Pools was 76.57%; the weighted average Mortgage Rate was 11.51% per annum; the
weighted average original term to stated maturity was 240 months; the weighted
average remaining term to stated maturity was 237 months; and 99.34% of the MCA
Loans were secured by first mortgages.


         PAM. The Sponsor acquired approximately 17.21% of the Mortgage Loans in
the Statistic Calculation Pools from PacificAmerica Money Center, Inc., an
Unaffiliated Originator (such mortgage loans, the "PAM Loans" together with the
MCA Loans, the "Unaffiliated Originator Loans"). PacificAmerica Money Center,
Inc. is headquartered in Woodland Hills, CA and is engaged in originating
mortgage loans through retail and wholesale channels. The PAM Loans consist of
936 Mortgages representing an aggregate principal balance of $89,472,645.31 as
of the Cut-Off Date. Approximately 32.65% (by aggregate principal balance as of
the Cut-Off Date) of the PAM Loans are included in the Fixed Rate Group and
approximately 67.35% of the PAM Loans are included in the Adjustable Rate Group.
The PAM Loans are related to properties located in 33 states and the District of
Columbia.

         Prior to its purchase of the PAM Loans, the Sponsors performed or
caused to be performed an operational review of the origination practices of
PAM. The Sponsor has been acquiring Mortgage Loans from PAM since mid-1995.

         As of the Cut-Off Date, the weighted average CLTV of the PAM Loans was
72.45%, the weighted average Mortgage Rate was 11.32% per annum; the weighted
average original term to stated maturity was 346 months; the weighted average
remaining term to stated maturity was 345 months and 95.34% of the PAM Loans
were secured by first mortgages.

Bulk Acquisitions.

         Loans representing 14.63% of the aggregate principal balance of
Mortgage Loans as of the Statistic Calculation Date were purchased in Bulk
Acquisitions by the Sponsor in the second half of 1996 and such loans were
originated in accordance with the Sponsor's Bulk Guidelines. See "Mortgage Loan
Program -Underwriting Guidelines -- Bulk Guidelines" in the Prospectus. All of
the loans acquired in these transactions were acquired "servicing released";
i.e., Advanta Mortgage Corp. USA acts as the Master Servicer. All Mortgage Loans
so purchased or to be so purchased are hereinafter referred to as the "Bulk
Loans."

         As of the Statistic Calculation Date, the weighted average CLTV of the
Bulk Loans was 74.42%. The weighted average Mortgage Rate of the Bulk Loans was
10.48% per annum and the weighted average remaining term to maturity was 312
months with approximately 23 months of seasoning. As of the Statistic
Calculation Date, the Bulk Loans were comprised of 99.98% first liens.

Delinquencies

         Owned and Managed Servicing Portfolio. The following tables set forth
information relating to the delinquency, loan loss and foreclosure experience of
the Master Servicer for its servicing portfolio, excluding certain loans
serviced by the Master Servicer that were not originated or purchased and
reunderwritten by the Sponsor or its Affiliated Originators (the "Owned and
Managed Servicing Portfolio"), of fixed and variable rate mortgage loans as of
December 31, 1996 and for each of the four prior years. The Owned and Managed
Servicing Portfolio includes, but is not limited to, the Mortgage Loans acquired
on or prior to December 31, 1996, which are contained in the Mortgage Loan Pool.
In addition to the Owned and Managed Servicing Portfolio, the Master Servicer

serviced, as of December 31, 1996, approximately 62,800 mortgage loans with an
aggregate principal balance as of such date of approximately $3.7 billion; such
loans were not originated

(1)  "Average Amount Outstanding" during the period is the arithmetic average of
     the principal balances of the mortgage loans outstanding on the last
     business day of each month during the period.

(2)  "Gross Losses" are amounts which have been determined to be uncollectible
     relating to mortgage loans for each respective period.

(3)  "Recoveries" are recoveries from liquidation proceeds and deficiency 
     judgments.

(4)  "Net Losses" represents "Gross Losses" minus "Recoveries".

     The Master Servicer experienced an increase in the net loss rate on its 
Owned and Managed Portfolio during the period 1990 through 1994.  It believes
that such increase was due to four primary factors: the  seasoning of its
portfolio, economic conditions, a decline in property values in certain regions
and the acceleration of charge-offs on loans in 1994.  In addition, the level of
net losses during such period was negatively impacted by the performance of the
Non-Income Verification ("NIV") loan program.  The net loss rates as a
percentage of the average amount outstanding on its Owned and Managed Portfolio,
excluding NIV loans, are 1.42%, 0.88% and 0.45% for the periods ending December
31, 1994, December 31, 1993 and December 31, 1992, respectively.*

                            THE MORTGAGE LOAN POOL


General

         The Mortgage Loans will be predominantly home equity loans, i.e., loans
used (x) to refinance an existing mortgage loan on more favorable terms, (y) to
consolidate debt, or (z) to obtain cash proceeds by borrowing against the
Mortgagor's equity in the related Mortgaged Property.

         The Statistic Calculation Pools contained 7,165 Mortgage Loans to be
sold by the Sponsor to the Trust evidenced by promissory notes (the "Notes")
secured by Mortgages on the Mortgaged Properties, which are located in 48 states
and the District of Columbia. The Mortgaged Properties securing the Mortgage
Loans consist primarily of single-family residences (which may be detached, part
of a two-to four-family dwelling, a condominium unit or a unit in a planned unit
development). The Mortgaged Properties may be owner-occupied (which includes
second and vacation homes) and non-owner occupied investment properties. Unless
otherwise noted, all statistical percentages in this Prospectus Supplement are
measured by the aggregate principal balance of the related Statistic Calculation
Pool.

         The Mortgage Loans will be required to satisfy the following criteria
as of the Cut-Off Date: have remaining terms to maturity of no greater than 30
years; will not be 30 or more days delinquent (except that certain Mortgage
Loans, representing in the aggregate not in excess of 4.00% of the aggregate
principal balance of all Mortgage Loans as of the Cut-Off Date, may be 30-89
days delinquent) and, with respect to fixed-rate Mortgage Loans, have a Mortgage
Rate as of the Cut-Off Date of at least 6.875%. Neither the Sponsor nor the
Master Servicer have reason to believe that the delinquency and loss experience
of the Mortgage Loans will differ in any material respect from that of the
Master Servicer's total servicing portfolio, although there can be no assurance
that this will be the case.

         Less than 14.30% of the Mortgage Loans (as a percentage of the
aggregate principal balance of all Mortgage Loans contained in the Statistic
Calculation Pools) are "simple interest" or "date of payment" loans, with the
remainder "actuarial" or "pre-computed" loans with the exception of one "rule of
78's" loan. 94.23% of the Mortgage Loans are secured by first lien mortgages on
the related Mortgaged Properties and 5.77% of the Mortgage Loans are secured by
junior liens on the related Mortgaged Properties.

         Each Mortgage Loan in the Trust will be assigned to one of two mortgage
loan groups (the "Fixed Rate Group" and the "Adjustable Rate Group",
respectively, and each a "Mortgage Loan Group"). 100% of the Mortgage Loans
contained in Fixed Rate Group will be secured by a Mortgage having either a
first or junior lien position with respect to the related Mortgaged Property and
will have a maximum remaining term to maturity of 30 years. The Mortgage Loans
contained in the Adjustable Rate Group will be secured by a Mortgage having
either a first or a junior lien position with respect to the related Mortgaged
Property and will have a maximum remaining term to maturity of 30 years. The
Fixed Rate Group Certificates represent undivided ownership interests in all
Mortgage Loans contained or to be contained in the Fixed Rate Group and the
Adjustable Rate Group Certificates represent undivided ownership interests in
all Mortgage Loans contained or to be contained in the Adjustable Rate Group.

         The CLTVs and LTVs described herein were calculated based upon the

appraised values of the related Mortgaged Properties at the time of origination
(the "Appraised Values"). In general, for purchase money loans, the CLTVs and
LTVs were calculated using the lower of the purchase price or appraised values
of the related Mortgaged Properties at the time of origination. No assurance can
be given that such appraised values of the Mortgaged Properties have remained or
will remain at their levels on the dates of origination of the related Mortgage
Loans. If property values decline such that the outstanding balances 

                                     S-37

<PAGE>

of the Mortgage Loans, together with the outstanding balances of any Senior
Liens, become equal to or greater than the value of the Mortgaged Properties,
the actual rates of delinquencies, foreclosures and losses could be higher than
those heretofore experienced by the Master Servicer, as set forth above under
"The Portfolio of Mortgage Loans," and in the mortgage lending industry.

          Difference between Statistic Calculation Pools and Closing Date Pools.

          The statistical information presented in this Prospectus Supplement is
based on Statistic Calculation Pools. The Statistic Calculation Pools reflect
the Mortgage Loans acquired by the Sponsor through the Cut-Off Date, and the
statistical information presented herein is based on the number and the
principal balances of such Mortgage Loans as of the Cut-Off Date. These pools
aggregated $315,000,035.21 with respect to the Fixed Rate Group and
$205,000,731.13 with respect to the Adjustable Rate Group. The Sponsor expects
that the actual pools as of the Closing Date will represent approximately
$340,000,000 in Mortgage Loans in the Fixed Rate Group and approximately
$210,000,000 in Mortgage Loans in the Adjustable Rate Group. The additional
Mortgage Loans to be included in the final pools will represent Mortgage Loans
acquired or to be acquired by the Sponsor on or prior to the Closing Date. In
addition, with respect to the Statistic Calculation Pools, as to which
statistical information is presented herein, some amortization of the Mortgage
Loans contained in such pools will occur prior to the Closing Date. Moreover,
certain loans included in the Statistic Calculation Pools may prepay in full or
may be determined not to meet the eligibility requirements for the final pools
and as a result may not be included in the final pools. As a result of the
foregoing, the statistical distribution of characteristics as of the Closing
Date for the final Mortgage Loan pools will vary somewhat from the statistical
distribution of such characteristics of the Statistic Calculation Pools as
presented in this Prospectus Supplement, although such variance will not be
material. In the event that the Sponsor does not, as of the Closing Date, have
the full amount of Mortgage Loans which the Sponsor expects to sell to the Trust
on such date, (i.e., approximately $340,000,000 with respect to Fixed Rate Group
and approximately $210,000,000 with respect to the Adjustable Rate Group) the
Sponsor will reduce the size of the offering. The Sponsor does not expect that
the original principal amount of any class will increase or decrease by more
than 5% as a result of such non-delivery. Even if the full expected amount of
Mortgage Loans is delivered, certain adjustments (plus or minus 5%) may occur
between the class sizes.

The Fixed Rate Group


         The Mortgage Loans in the Fixed Rate Group Statistic Calculation Pool
consist of 5,219 loans under which the related Mortgaged Properties are located
in 48 states and the District of Columbia, as set forth herein. The Fixed Rate
Group Statistic Calculation Pool had an aggregate principal balance of
$315,000,035.21, the minimum principal balance of any of the Mortgage Loans in
the Fixed Rate Group Statistic Calculation Pool was $2,946.92 the maximum
principal balance thereof was $544,000.00 and the average principal balance of
such Mortgage Loans was approximately $60,356.40. The Mortgage Rates on the
Mortgage Loans in the Fixed Rate Group Statistic Calculation Pool ranged from
6.88% to 18.15% per annum, and the weighted average Mortgage Rate of such
Mortgage Loans was 11.04% per annum. The original term to stated maturity of the
Mortgage Loans in the Fixed Rate Group Statistic Calculation Pool ranged from 24
months to 360 months, the remaining term to stated maturity ranged from 17
months to 360 months, the weighted average original term to stated maturity was
243 months, the weighted average remaining term to stated maturity was 238
months and the weighted average seasoning was 5 months. No Mortgage Loan in the
Fixed Rate Group Statistic Calculation Pool had a stated maturity later than
March 25, 2027. 68.67% of the Mortgage Loans in the Fixed Rate Group Statistic
Calculation Pool by aggregate principal balance require monthly payments of
principal that will fully amortize the Mortgage Loans by their respective
maturity dates, and 31.33% of such Mortgage Loans by aggregate principal balance
are Balloon Loans.

<PAGE>

         The weighted average CLTV of the Mortgage Loans included in the Fixed
Rate Group Statistic Calculation Pool was 75.25%. The weighted average Junior
Lien Ratio (as defined below) of the Mortgage Loans in the Fixed Rate Group
Statistic Calculation Pool was 36.94%; the weighted average LTV was 70.69%.
Approximately 91% of the Mortgage Loans in the Fixed Rate Group Statistic
Calculation Pool by aggregate principal balance were secured by first mortgages
and approximately 9% by junior mortgages.

         The "Junior Lien Ratio" of a Mortgage Loan which is in a junior lien
position is equal to the ratio (expressed as a percentage) of the original
principal balance of such Mortgage Loan to the sum of (i) the original principal
balance of such Mortgage Loan and (ii) the principal balance at the time of
origination of the Mortgage Loan of any Senior Liens (computed at the time of
origination of such Mortgage Loan).

         The following tables describe the Fixed Rate Group Mortgage Loans and
the related Mortgaged Properties based upon the Fixed Rate Group Statistic
Calculation Pool as of the opening of business on the Cut-Off Date.

                     PREPAYMENT AND YIELD CONSIDERATIONS

         The weighted average life of, and, if purchased at other than par, the
yield to maturity on an Offered Certificate will be directly related to the rate
of payment of principal of the Mortgage Loans in the related Mortgage Loan
Group, including for this purpose voluntary payment in whole or in part of
Mortgage Loans in the Mortgage Loan Group prior to stated maturity (a
"Prepayment"), liquidations due to defaults, casualties and condemnations, and

repurchases of Mortgage Loans in the related Mortgage Loan Group by the Sponsor,
the Originators or the Master Servicer. The actual rate of principal prepayments
on pools of mortgage loans is influenced by a variety of economic, tax,
geographic, demographic, social, legal and other factors and has fluctuated
considerably in recent years. In addition, the rate of principal prepayments may
differ among pools of mortgage loans at any time because of specific factors
relating to the mortgage loans in the particular pool, including, among other
things, the age of the mortgage loans, the geographic locations of the
properties securing the loans and the extent of the mortgagors' equity in such
properties, and changes in the mortgagors' housing needs, job transfers and
unemployment.

         The timing of changes in the rate of prepayments may significantly
affect the actual yield to investors, even if the average rate of principal
prepayments is consistent with the expectations of investors. In general, the
earlier the payment of principal of the Mortgage Loans the greater the effect on
an investor's yield to maturity. As a result, the effect on an investor's yield
of prepayments occurring at a rate higher (or lower) than the rate anticipated
by the investor during the period immediately following the issuance of the
Offered Certificates will not be offset by a subsequent like reduction (or
increase) in the rate of principal prepayments. Investors must make their own
decisions as to the appropriate prepayment assumptions to be used in deciding
whether to purchase any of the Offered Certificates. The Sponsor makes no
representations or warranties as to the rate of prepayment or the factors to be
considered in connection with such determination.

Projected Prepayments and Yields for Offered Certificates

         If purchased at other than par, the yield to maturity on an Offered
Certificate will be affected by the rate of the payment of principal of the
Mortgage Loans in the related Mortgage Loan Group. If the actual rate of
payments on the Mortgage Loans in the related Mortgage Loan Group is slower than
the rate anticipated by an investor who purchases an Offered Certificate of the
related class at a discount, the actual yield to such investor will be lower
than such investor's anticipated yield. If the actual rate of payments on the
Mortgage Loans in the related Mortgage Loan Group is faster than the rate
anticipated by an investor who purchases an Offered Certificate of the related
class at a premium, the actual yield to such investor will be lower than such
investor's anticipated yield.

         The Mortgage Loans in the Fixed Rate Group are primarily fixed-rate
mortgage loans. The rate of prepayments with respect to conventional fixed rate
mortgage loans has fluctuated significantly in recent years. In general, if
prevailing interest rates fall significantly below the interest rates on fixed
rate mortgage loans, such mortgage loans are likely to be subject to higher
prepayment rates than if prevailing rates remain at or above the interest rate
on such mortgage loans. However, the monthly payment on mortgage loans similar
to the Mortgage Loans is often smaller than the monthly payment on a
purchase-money first mortgage loan. Consequently, a decrease in the interest
rate payable as a result of a refinancing would result in a relatively small
reduction in the amount of the Mortgagor's monthly payment, as a result of the
relatively small loan balance. Conversely, if prevailing interest rates rise
appreciably above the interest rates on fixed rate mortgage loans, such mortgage
loans are likely to experience a lower prepayment rate than if prevailing rates

remain at or below the interest rates on such 

                                     S-57

mortgage loans. 62.84% of the Mortgage Loans in the Fixed Rate Group Statistic
Calculation Pool by aggregate principal balance had prepayment penalties.

         All of the Mortgage Loans in Adjustable Rate Group are adjustable rate
mortgage loans. 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. However, no assurance
can be given as to the level of prepayments that the Mortgage Loans will
experience. 61.55% of the Mortgage Loans in the Adjustable Rate Group Statistic
Calculation Pool by aggregate principal balance had prepayment penalties.

         "Weighted average life" refers to the average amount of time that will
elapse from the date of issuance of a security until each dollar of principal of
such security will be repaid to the investor. The weighted average life of the
Offered Certificates of each class will be influenced by the rate at which
principal payments on the Mortgage Loans in the related Mortgage Loan Pool are
paid, which may be in the form of scheduled amortization, accelerated
amortization or prepayments (for this purpose, the term "prepayment" includes
Prepayments and liquidations due to default) or as a result of an early
termination of the Trust.

         The model used in this Prospectus Supplement is a prepayment assumption
(the "Prepayment Assumption") which represents an assumed rate of prepayment
each month relative to the then outstanding principal balance of a pool of
mortgage loans for the life of such mortgage loans. The "100% Prepayment
Assumption" assumes a conditional prepayment rate of 3% per annum of the then
outstanding principal balance of the Mortgage Loans in the first month of the
life of the Mortgage Loans and an additional 1.55% (precisely, 17/11%) per annum
in each month thereafter until the twelfth month. Beginning in the twelfth month
and in each month thereafter during the life of the Mortgage Loans, the 100%
Prepayment Assumption assumes a conditional prepayment rate of 20% per annum
each month. As used in the table below, 0% Prepayment Assumption assumes
prepayment rates equal to 0% of the Prepayment Assumption, i.e., no prepayments
on the synthetic mortgage loans having the characteristics described below.
Correspondingly, 100% Prepayment Assumption assumes prepayment rates equal to
100% of the Prepayment Assumption, and so forth. The Prepayment Assumption does
not purport to be a historical description of prepayment experience or a
prediction of the anticipated rate of prepayment of any pool of mortgage loans,
including the related Mortgage Loans. The Sponsor believes that no existing
statistics of which it is aware provide a reliable basis for holders of Offered
Certificates to predict the amount or the timing of receipt of prepayments on
the Mortgage Loans.


         The tables below were prepared on the basis of the assumptions in the
following paragraph and there are discrepancies between the characteristics of
the actual Mortgage Loans and the characteristics of the Mortgage Loans assumed
in preparing the tables. Any such discrepancy may have an effect upon the
percentages of the Class A Certificate Principal Balances outstanding and
weighted average lives of the Offered Certificates set forth in the tables. In
addition, since the actual Mortgage Loans in each Mortgage Loan Group have
characteristics which differ from those assumed in preparing the tables set
forth below, the distributions of principal on the Offered Certificates may be
made earlier or later than as indicated in the tables.

(1) To Maturity

(2) To 10% Call

(3) This assumes that an optional termination is exercised by the Master
    Servicer when the aggregate principal balance has declined to 10% or less of
    the aggregate principal balance of the Mortgage Loans as of the Closing
    Date.

The weighted average life of each indicated class of Offered Certificates has
been determined by (i) multiplying the amount of each principal payment by the
number of years from the date of issuance to the related Payment Date, (ii)
adding the results and (iii) dividing the sum of the initial respective
Certificate Principal Balance for the related Offered Certificates as of the
Closing Date.

(1) To Maturity

(2) To 10% Call

(3) This assumes that an optional termination is exercised by the Master
    Servicer when the aggregate principal balance has declined to 10% or less of
    the aggregate principal balance of the Mortgage Loans as of the Closing
    Date.

The weighted average life of each indicated class of Offered Certificates has
been determined by (i) multiplying the amount of each principal payment by the
number of years from the date of issuance to the related Payment Date, (ii)
adding the results and (iii) dividing the sum of the initial respective
Certificate Principal Balance for the related Offered Certificates as of the
Closing Date.

(1) To Maturity

(2) To 10% Call


(3) This assumes that an optional termination is exercised by the Master
    Servicer when the aggregate principal balance has declined to 10% or less of
    the aggregate principal balance of the Mortgage Loans as of the Closing
    Date.

The weighted average life of each indicated class of Offered Certificates has
been determined by (i) multiplying the amount of each principal payment by the
number of years from the date of issuance to the related Payment Date, (ii)
adding the results and (iii) dividing the sum of the initial respective
Certificate Principal Balance for the related Offered Certificates as of the
Closing Date.

(1) To Maturity

(2) To 10% Call

(3) This assumes that an optional termination is exercised by the Master
    Servicer when the aggregate principal balance has declined to 10% or less of
    the aggregate principal balance of the Mortgage Loans as of the Closing
    Date.

The weighted average life of each indicated class of Offered Certificates has
been determined by (i) multiplying the amount of each principal payment by the
number of years from the date of issuance to the related Payment Date, (ii)
adding the results and (iii) dividing the sum of the initial respective
Certificate Principal Balance for the related Offered Certificates as of the
Closing Date.

(3) This assumes that an optional termination is exercised by the Master
    Servicer when the aggregate principal balance has declined to 10% or less of
    the aggregate principal balance of the Mortgage Loans as of the Closing

The weighted average life of each indicated class of Offered Certificates has
been determined by (i) multiplying the amount of each principal payment by the
number of years from the date of issuance to the related Payment Date, (ii)
adding the results and (iii) dividing the sum of the initial respective
Certificate Principal Balance for the related Offered Certificates as of the
Closing Date.

                               USE OF PROCEEDS

         The Sponsor will cause the Trust to acquire the Mortgage Loans
concurrently with the sale of the Offered Certificates. The net proceeds from
the sale of the Offered Certificates will be paid over to the Originators in
consideration of the transfer of the Mortgage Loans. Such amount will be
determined as a result of the pricing of the Offered Certificates through the
offering described in this Prospectus Supplement. The net proceeds to be
received from the sale of the Mortgage Loans will be added to the Originators'
general funds and will be available for general corporate purposes, including
the repayment of debt and the purchase of new mortgage loans.

                     THE SPONSOR AND THE MASTER SERVICER

         The Sponsor, Advanta Mortgage Conduit Services, Inc. is a direct
subsidiary of Advanta Mortgage Corp. USA, the Master Servicer, and is an
indirect subsidiary of Advanta Corp., a Delaware corporation ("Advanta Parent"),
a publicly-traded company based in Horsham, Pennsylvania with assets as of
December 31, 1996 in excess of $5.6 billion. Advanta Parent, through its
subsidiaries (including the Master Servicer) managed assets (including mortgage

loans) in excess of $19.2 billion as of December 31, 1996. See "The Sponsor and
the Transferor" in the Prospectus.

         As of December 31, 1996, the Master Servicer and its subsidiaries were
servicing approximately 43,300 Mortgage Loans in the Owned and Managed Servicing
Portfolio representing an aggregate outstanding principal balance of
approximately $2.6 billion, and approximately 62,800 mortgage loans in the
Third-Party Servicing Portfolio representing an aggregate outstanding principal
balance of approximately $3.7 billion. See "The Master Servicer" in the
Prospectus.

         As of December 31, 1996, the Sponsor or its affiliates have issued, and
the Master Servicer services, 32 issues of mortgage pass-through securities with
an original balance of approximately $4 billion.

         The Trustee may remove the Master Servicer, and the Master Servicer may
resign, only in accordance with the terms of the Pooling and Servicing
Agreement. No removal or resignation shall become effective until the Trustee or
a successor servicer shall have assumed the Master Servicer's responsibilities
and obligations in accordance therewith. See "The Pooling and Servicing
Agreement -Removal and Resignation of the Master Servicer" in the Prospectus.

         The Master Servicer may not assign its obligations under the Pooling
and Servicing Agreement, in whole or in part, unless it shall have first
obtained the written consent of the Trustee, which consent is required not to be
unreasonably withheld; provided, however, that any assignee must meet the
eligibility requirements for a successor servicer set forth in the Pooling and
Servicing Agreement. See "The Pooling and Servicing Agreement -- Removal and
Resignation of the Master Servicer" in the Prospectus.

         The Master Servicer may enter into Sub-Servicing Agreements with
qualified Sub-Servicers with respect to the servicing of all or any portion of
the Mortgage Loans. The Pooling and Servicing Agreement will provide that
affiliates of the Master Servicer which are qualified to service mortgage loans
are qualified Sub-Servicers. No Sub-Servicing Agreements discharge the Master
Servicer from its servicing obligations. See "Mortgage Loan Program --
Sub-Servicers" in the Prospectus.

         Upon removal or resignation of the Master Servicer, the Trustee may
solicit bids for a successor servicer and, pending the appointment of a
successor Servicer as a result of soliciting such bids, will be required to
serve as Master Servicer. If the Trustee is unable to obtain a qualifying bid
and is prevented 

                                     S-73

<PAGE>

by law from acting as servicer, the Trustee will be required to appoint, or
petition a court of competent jurisdiction to appoint, an eligible successor.
Any successor is required to be a housing and home finance institution, bank or
mortgage servicing institution which is acceptable to the Trustee and shall
assume all or any part of the responsibilities, duties or liabilities of the
Master Servicer.


         The Offered Certificates will not represent an interest in or
obligation of, nor are the Mortgage Loans guaranteed by, the Sponsor, the Master
Servicer or Advanta Parent, nor will they be insured or guaranteed by the
Federal Deposit Insurance Corporation (the "FDIC") or any other governmental
agency or instrumentality.

Recent Developments related to Advanta Parent

         On March 17, 1997, Advanta Parent announced that it expects to report
1997 results well below previous expectations. Advanta Parent currently expects
to report, for the first quarter of 1997, a loss in the area of $20 million
compared to earnings of $41 million in the first quarter of 1996. Such results
are attributed to a number of factors, including continuing increases in
consumer bankruptcies and charge-offs and lower receivables balances than
originally anticipated in its credit card business. Advanta Parent also
announced it expects to report a net profit for full year 1997, with estimated
full year earnings of approximately $1.50 per share.

         Advanta Parent also announced that it has retained BT Wolfensohn, a
division of Bankers Trust New York Corporation, to explore all strategic
alternatives that build upon the historic strength and success of Advanta Parent
as a whole and of its business units, including the Sponsor and/or the Master
Servicer, with the aim of maximizing Advanta Parent's value. The strategic
alternatives that might be considered by Advanta Parent include, but are not
limited to, a strategic alliance with another company, an alliance or initial
public offering involving one or more of Advanta Parent's operating units, or a
merger or sale involving Advanta Parent as a whole. There is no assurance that
any such event will occur. The result of pursuing such alternatives may
positively, or may adversely, affect the financial ability of the Sponsor and/or
the Master Servicer to perform their financial and other obligations, or to
service the Mortgage Loan pool. In the event that such effects on the Sponsor
and/or the Master Servicer are adverse, losses and delinquencies on the Mortgage
Loan pool may increase.

         Advanta Parent has reported that its overall charge-off rate on all
managed receivables (for which the mortgage loan portfolio represents less than
20%), for the year ended December 31, 1996, was 3.2%, compared to 2.2% for the
year ended December 31, 1995. Advanta Parent has further reported that its
overall delinquency ratio (30 days or more) for all managed receivables at
December 31, 1996 was 5.4%, compared to 3.3% at December 31, 1995.

         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 the Sponsor and the Master Servicer, insofar
as they relate to the Trust and the Offered Certificates, primarily consist of
the Sponsor's obligation to repurchase the Master Servicer's obligation to
service the Mortgage Loan pool. To the extent that the Sponsor and/or the Master
Servicer's ability to perform such obligations is adversely affected, the
Mortgage Loan pool may experience an increased level of delinquencies and
losses. The credit enhancement available to the Trust, however, will be
available, under the circumstances described herein under "Credit Enhancement"
to absorb certain losses, as described herein.

                       DESCRIPTION OF THE CERTIFICATES

General

         Persons in whose name an Offered Certificate is registered in the
Register maintained by the Trustee are the "Owners" of the Offered Certificates.
For so long as the Offered Certificates are in book-entry form with DTC, the
only "Owner" of the Offered Certificates as the term "Owner" is used in the
Pooling and Servicing Agreement will be Cede. No Beneficial Owner will be
entitled to receive a Definitive Certificate representing such person's interest
in the Trust, except in the event that Definitive Certificates are issued under
limited circumstances set forth in the Pooling and Servicing Agreement. All
references herein to the Owners of Offered Certificates shall mean and include
the rights of Beneficial Owners, as such rights may be exercised through DTC and
its participating organizations, except as otherwise specified in the Pooling
and Servicing Agreement. See "Description of the Securities -- Form of
Securities" in the Prospectus.

         Each class of Offered Certificates will evidence the right to receive
on each Payment Date such Class' Distribution Amount for such class of Offered
Certificates, in each case until the related Certificate Principal Balance has
been reduced to zero. The Owners of the class of Class R Certificates will be
entitled to receive distributions of residual Net Monthly Excess Cashflow not
required for other purposes pursuant to the Pooling and Servicing Agreement.

Remittance Dates

         The Pooling and Servicing Agreement will require that the Trustee
create and maintain a Distribution Account. See "Description of the Securities
- -- Payments on Mortgage Loans; Deposits to Distribution Account" in the
Prospectus.

         On the eighteenth day of each month (or, if such day is not a Business
Day, the immediately preceding Business Day) (the "Remittance Date") the Master
Servicer is required to withdraw from the Principal and Interest Account and
remit to the Trustee, for deposit in the Distribution Account, the Monthly
Remittance Amount. The Monthly Remittance Amount is the sum of the amounts
collected by the Master Servicer in respect of the Mortgage Loans during the
period beginning on the first day of the calendar month immediately preceding
the month in which the related Remittance Date occurs and ending on the last day
of such month (the "Remittance Period") plus any related Loan Purchase Prices,
Substitution Amounts, Delinquency Advances and Compensating Interest, less the
sum of certain amounts the Master Servicer is permitted to withdraw from the
Principal and Interest Account, as described under "Description of the
Securities -- Withdrawals from the Principal and Interest Account."

Book Entry Registration of the Offered Certificates

         The Offered Certificates will be book-entry certificates (the

"Book-Entry Certificates"). The Beneficial Owners may elect to hold their
Offered Certificates through DTC in the United States, or CEDEL or Euroclear in
Europe if they are participants of such systems ("Participants"), or indirectly
through organizations which are Participants in such systems. The Book-Entry
Certificates will be issued in one or more certificates per class of Offered
Certificates which in the aggregate equal the principal balance of such Offered
Certificates and will initially be registered in the name of Cede & Co., the
nominee of DTC. CEDEL and Euroclear will hold omnibus positions on behalf of
their Participants through customers' securities accounts in CEDEL's and
Euroclear's names on the books of their respective depositaries which in turn
will hold such positions in customers' securities accounts in the depositaries'
names on the books of DTC. Citibank will act as depositary for CEDEL and Morgan
will act as depositary for Euroclear (in such capacities, individually the
"Relevant Depositary" and collectively the 

                                     S-75

<PAGE>

"European Depositaries"). Investors may hold such beneficial interests in the
Book-Entry Certificates in minimum denominations representing principal amounts
of $1,000 and in integral multiples in excess thereof. Except as described
below, no Beneficial Owner will be entitled to receive a Definitive Certificate.
Unless and until Definitive Certificates are issued, it is anticipated that the
only "Owner" of such Offered Certificates will be Cede & Co., as nominee of DTC.
Beneficial Owners will not be Owners as that term is used in the Pooling and
Servicing Agreement. Beneficial Owners are only permitted to exercise their
rights indirectly through Participants and DTC.

         The Beneficial Owner's ownership of a Book-Entry Certificate will be
recorded on the records of the brokerage firm, bank, thrift institution or other
financial intermediary (each, a "Financial Intermediary") that maintains the
Beneficial Owner's account for such purpose. In turn, the Financial
Intermediary's Ownership of such Book-Entry Certificate will be recorded 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 DTC Participant and on
the records of CEDEL or Euroclear, as appropriate).

         Beneficial Owners will receive all distributions of principal of, and
interest on, the Offered Certificates from the Trustee through DTC and DTC
Participants. While such Offered Certificates are outstanding (except under the
circumstances described below), under the rules, regulations and procedures
creating and affecting DTC and its operations (the "Rules"), DTC is required to
make book-entry transfers among Participants on whose behalf it acts with
respect to such Offered Certificates and is required to receive and transmit
distributions of principal of, and interest on, such Offered Certificates.
Participants and indirect participants with whom Beneficial Owners have accounts
with respect to Offered Certificates are similarly required to make book-entry
transfers and receive and transmit such distributions on behalf of their
respective Beneficial Owners. Accordingly, although Beneficial Owners will not
possess certificates, the Rules provide a mechanism by which Beneficial Owners
will receive distributions and will be able to transfer their interest.


         Beneficial Owners will not receive or be entitled to receive
certificates representing their respective interests in the Offered
Certificates, except under the limited circumstances described below. Unless and
until Definitive Certificates are issued, Beneficial Owners who are not
Participants may transfer ownership of Offered Certificates only through
Participants and indirect participants by instructing such Participants and
indirect participants to transfer such Offered Certificates, by book-entry
transfer, through DTC for the account of the purchasers of such Offered
Certificates, which account is maintained with their respective Participants.
Under the Rules and in accordance with DTC's normal procedures, transfers of
ownership of such Offered Certificates will be executed through DTC and the
accounts of the respective Participants at DTC will be debited and credited.
Similarly, the Participants and indirect participants will make debits or
credits, as the case may be, on their records on behalf of the selling and
purchasing 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 or CEDEL Participants on such business day. Cash received in CEDEL or
Euroclear as a result of sales of securities by or through a CEDEL Participant
(as defined below) or Euroclear Participant (as defined below) to a DTC
Participant will be received with value on the DTC settlement date but will be
available in the relevant CEDEL or Euroclear cash account only as of the
business day following settlements in DTC. For information with respect to tax
documentation procedures relating to the Certificates, see "Certain Federal
Income Tax Consequences -- Foreign Investors" and " -- Backup Withholding" in
the Prospectus and "Global Clearance, Settlement and Tax Documentation
Procedures -- Certain U.S. Federal Income Tax Documentation Requirements" in
Annex I to this Prospectus Supplement.

         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 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 ("DTC Participants"), some of which
(and/or their representatives) own DTC. In accordance with its normal
procedures, DTC is expected to record the positions held by each DTC Participant
in the Book-Entry Certificates, whether held for its own account or as a nominee
for another person. In general, beneficial ownership of Book-Entry Certificates
will be subject to the rules, regulations and procedures governing DTC and DTC
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 participant 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 depository, 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 participants of
Euroclear ("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 now be settled in any of 27 currencies, including United
States dollars. Euroclear includes various other services, including securities
lending and borrowing and interfaces with domestic markets in several countries
generally similar to the arrangements for cross-market transfers with DTC
described above. Euroclear is operated by the Brussels, Belgium office of Morgan
Guaranty Trust Company of New York (the "Euroclear Operator"), under contract
with Euroclear Clearance Systems S.C., a Belgian cooperative corporation (the
"Cooperative"). All operations are conducted by the Euroclear Operator, and all
Euroclear Securities clearance accounts and Euroclear cash accounts are accounts
with the Euroclear Operator, not the Cooperative. The Cooperative establishes
policy for Euroclear on behalf of Euroclear Participants. Euroclear Participants
include banks (including central banks), securities brokers and dealers and
other professional financial intermediaries. Indirect access to Euroclear is
also available to other firms 

                                     S-77

<PAGE>


that clear through or maintain a custodial relationship with a Euroclear
Participant, either directly or indirectly.

         The Euroclear Operator is the Belgian branch of a New York banking
corporation which is a member bank of the Federal Reserve System. As such, it is
regulated and examined by the Board of Governors of the Federal Reserve System
and the New York State Banking Department, as well as the Belgian Banking
Commission.

         Securities clearance accounts and cash accounts with the Euroclear
operator are governed by the Terms and Conditions Governing Use of Euroclear and
the related Operating Procedures of the Euroclear System and applicable Belgian
law (collectively, the "Terms and Conditions"). The Terms and Conditions govern
transfers of securities and cash within Euroclear, withdrawals of securities and
cash from Euroclear, and receipts of payments with respect to securities in
Euroclear. All securities in Euroclear are held on a fungible basis without
attribution of specific certificates to specific securities clearance accounts.
The Euroclear Operator acts under the Terms and Conditions only on behalf of
Euroclear Participants, and has no record of or relationship with persons
holding through Euroclear Participants.

         Distributions on the Book-Entry Certificates will be made on each
Payment Date by the Trustee to DTC. DTC will be responsible for crediting the
amount of such payments to the accounts of the applicable DTC Participants in
accordance with DTC's normal procedures. Each DTC Participant will be
responsible for disbursing such payment to the Beneficial Owners of the
Book-Entry Certificates that it represents and to each Financial Intermediary
for which it acts as agent. Each such Financial Intermediary will be responsible
for disbursing funds to the Beneficial Owners of the Book-Entry Certificates
that it represents.

         Under a book-entry format, Beneficial Owners of the Book-Entry 
Certificates may experience some delay in their receipt of payments, since such
payments will be forwarded by the Trustee to Cede.  Distributions with respect
to Offered Certificates held through CEDEL or Euroclear will be credited to the
cash accounts of CEDEL Participants or Euroclear Participants in accordance with
the relevant system's rules and procedures, to the extent received by the
Relevant Depositary. Such distributions will be subject to tax reporting in
accordance with relevant United States tax laws and regulations. Because DTC can
only act on behalf of Financial Intermediaries, the ability of a Beneficial
Owner to pledge Book-Entry Certificates, to persons or entities that do not
participate in the Depository system, or otherwise take actions in respect of
such Book-Entry Certificates, may be limited due to the lack of physical
certificates for such Book-Entry Certificates. In addition, issuance of the
Book-Entry Certificates in book-entry form may reduce the liquidity of such
Certificates in the secondary market since certain potential investors may be
unwilling to purchase Certificates for which they cannot obtain physical
certificates.

         Monthly and annual reports on the Trust provided by the Trustee to
Cede, as nominee of DTC, may be made available to Beneficial Owners upon
request, in accordance with the rules, regulations and procedures creating and
affecting the Depository, and to the Financial Intermediaries to whose DTC
accounts the Book-Entry Certificates of such Beneficial Owners are credited.


         DTC has advised the Trustee that, unless and until Definitive
Certificates are issued, DTC will take any action permitted to be taken by the
holders of the Book-Entry Certificates under the Pooling and Servicing Agreement
only at the direction of one or more Financial Intermediaries to whose DTC
accounts the Book-Entry Certificates are credited, to the extent that such
actions are taken on behalf of Financial Intermediaries whose holdings include
such Book-Entry Certificates. CEDEL or the Euroclear Operator, as the case may
be, will take any action permitted to be taken by an Owner under the Pooling and
Servicing Agreement on behalf of a CEDEL Participant or Euroclear Participant
only in accordance with 

                                     S-78

<PAGE>

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
Offered Certificates which conflict with actions taken with respect to other
Offered Certificates.

         Definitive Certificates will be issued to Beneficial Owners of the
Book-Entry Certificates, or their nominees, rather than to DTC, only if (a) DTC
or the Sponsor advises the Trustee in writing that DTC is no longer willing,
qualified or able to discharge properly its responsibilities as a nominee and
depository with respect to the Book-Entry Certificates and the Sponsor or the
Trustee is unable to locate a qualified successor, (b) the Sponsor, at its sole
option, elects to terminate a book-entry system through DTC or (c) DTC, at the
direction of the Beneficial Owners representing a majority of the outstanding
Percentage Interests of the Offered Certificates, advises the Trustee in writing
that the continuation of a book-entry system through DTC (or a successor
thereto) is no longer in the best interests of Beneficial Owners.

         Upon the occurrence of any of the events described in the immediately
preceding paragraph, the Trustee will be required to notify all Beneficial
Owners of the occurrence of such event and the availability through DTC of
Definitive Certificates. Upon surrender by DTC of the global certificate or
certificates representing the Book-Entry Certificates and instructions for
re-registration, the Trustee will issue Definitive Certificates, at the
Sponsor's expense and thereafter the Trustee will recognize the holders of such
Definitive Certificates as Owners under the Pooling and Servicing Agreement.

         Although DTC, CEDEL and Euroclear have agreed to the foregoing
procedures in order to facilitate transfers of Certificates among Participants
of DTC, CEDEL and Euroclear, they are under no obligation to perform or continue
to perform such procedures and such procedures may be discontinued at any time.

         Neither the Sponsor, the Master Servicer nor the Trustee will have any
liability for any actions taken by DTC or its nominee, Euroclear, or CEDEL,
including, without limitation, actions for any aspect of the records relating to
or payments made on account of beneficial ownership interests in the Offered
Certificates held by Euroclear, Cedel or Cede & Co., as nominee for DTC, or for
maintaining, supervising or reviewing any records relating to such beneficial

ownership interests.

Payment Dates

         Distributions on the Certificates are required to be made on each
Payment Date, commencing on April 25, 1997, to the Owners on each Record Date in
an amount equal to the product of such Owner's Percentage Interest and the
amount distributed in respect of such Certificateholders' class of such
Certificates on such Payment Date. See "Description of the Securities --
Distributions" in the Prospectus.

         On each Payment Date, the Owners of each Class of the Offered
Certificates will be entitled to receive from amounts then on deposit in the
certificate account established and maintained by the Trustee in accordance with
the Pooling and Servicing Agreement (the "Certificate Account") and until the
Certificate Principal Balance of such Class of Offered Certificates is reduced
to zero, and to the extent funds are available therefor, the related Current
Interest, any Interest Carry Forward Amount and the portion of the Principal
Distribution Amount, if any, allocated therefor as of such Payment Date,
allocated among the Classes of the Offered Certificates as described below.
Distributions will be made in immediately available funds to Owners of Offered
Certificates by wire transfer or otherwise, to the account of such Owner at a
domestic bank or other entity having appropriate facilities therefor, if such
Owner has so notified the Trustee, or by check mailed to the address of the
person entitled thereto as it appears on the register (the "Register")
maintained by the Trustee as registrar (the "Registrar"). Beneficial Owners may
experience some delay in the receipt of their payments due to the operations of
DTC. See "Risk Factors--Book-Entry Registration" in the Prospectus and
"Description of the Offered Certificates--Book 

                                     S-79

<PAGE>

Entry Registration of the Offered Certificates" herein and "Description of the
Certificates--Book Entry Registration" in the Prospectus.

         The Pooling and Servicing Agreement will provide that an Owner, upon
receiving the final distribution on such Owner's Certificate, will be required
to send such Certificate to the Trustee.

         Each Owner of record of the related Class of the Offered Certificates
will be entitled to receive such Owner's Percentage Interest in the amounts due
such Class on such Payment Date. The "Percentage Interest" of an Offered
Certificate as of any date of determination will be equal to the percentage
obtained by dividing the principal balance of such Certificate as of the Cut-Off
Date by the Certificate Principal Balance for the related Class of the Offered
Certificates as of the Cut-Off Date.

Distributions

         Upon receipt, the Trustee will be required to deposit into the
Certificate Account with respect to each Mortgage Loan Group (i) the total of
the principal and interest collections on the Mortgage Loans, including any Net

Liquidation Proceeds and any amounts advanced by the Master Servicer, remitted
by the Servicer, together with any Substitution Amount and any Loan Purchase
Price amount and (ii) the proceeds of any liquidation of the Trust Estate.

         The Pooling and Servicing Agreement establishes a pass-through rate on
each Class of the Offered Certificates (each, a "Pass-Through Rate") as set
forth in the Summary of Terms herein.

         On each Payment Date, the Trustee is required to make the following
disbursements and transfers from monies then on deposit in the Certificate
Account as specified below in the following order of priority of each such
transfer and disbursement with respect to interest and principal:

                  Interest: On each Payment Date the Interest Remittance Amount
with respect to each Mortgage Loan Group will be distributed in the following
order of priority:

         First, to the Trustee, the Trustee's Fee;

         Second, to the Owners of the Class A Certificates related to such
         Mortgage Loan Group, the related Class A Current Interest plus the
         related Class A Interest Carry Forward Amount with respect to each such
         Class of Class A Certificates without any priority among such Class A
         Certificates; provided, that if the Interest Amount Available is not
         sufficient to make a full distribution of interest with respect to all
         Classes of the Class A Certificates, the Interest Amount Available will
         be distributed among the outstanding Classes of Class A Certificates
         pro rata based on the aggregate amount of interest due on each such
         Class, and the amount of the shortfall will be carried forward with
         accrued interest;

         Third, to the extent of the Interest Amount Available with respect to
         such Mortgage Loan Group then remaining, to the Owners of the Class M-1
         Certificates related to such Mortgage Loan Group,the related Class M-1
         Current Interest;

         Fourth, to the extent of the Interest Amount Available with respect to
         such Mortgage Loan Group then remaining, to the Owners of the Class M-2
         Certificates related to such Mortgage Loan Group, the related Class M-2
         Current Interest;

                                     S-80

<PAGE>

         Fifth, to the extent of the Interest Amount Available with respect to
         such Mortgage Loan Group then remaining, to the Owners of the Class B
         Certificates related to such Mortgage Loan Group, the related Class B
         Current Interest; and

         Sixth, the Monthly Excess Cashflow Amount with respect to such Mortgage
         Loan Group shall be applied as described under "Credit
         Enhancement--Application of Monthly Excess Cashflow Amount."


         Principal: With respect to each Mortgage Loan Group on each Payment
Date (a) before the related Stepdown Date or (b) with respect to which a Trigger
Event is in effect with respect to the related Mortgage Loan Group, Owners of
the Class A Certificates will be entitled to receive payment of 100% of the
Principal Distribution Amount with respect to such Mortgage Loan Group as
follows: in the case of the Fixed Rate Group, first, to the Owners of the Class
A-5 Certificates, the Class A-5 Lockout Distribution Amount and then to the
Owners of the Class A Certificates related to the Fixed Rate Group, in
sequential order until the Certificate Principal Balance of each Class of Class
A Certificates has been reduced to zero and in the case of the Adjustable Rate
Group, to the Owners of the Class A-6 Certificates until the Class A-6
Certificate Principal Balance has been reduced to zero.

         With respect to each Mortgage Loan Group on each Payment Date (a) on or
after the related Stepdown Date and (b) as long as a Trigger Event is not in
effect with respect to the related Mortgage Loan Group and is not continuing,
the Owners of all Classes of the Offered Certificates will be entitled to
receive payments of principal, in the order of priority, in the amounts set
forth below and to the extent of the Principal Distribution Amount with respect
to such Mortgage Loan Group as follows:

         First, in the case of the Fixed Rate Group, the lesser of (x) the
         Principal Distribution Amount with respect to such Mortgage Loan Group
         and (y) the Class A Principal Distribution Amount with respect to such
         Mortgage Loan Group shall be distributed to the Owners of the Class A-5
         Certificates, in an amount equal to the Class A-5 Lockout Distribution
         Amount, with the remainder paid to the Owners of the Class A
         Certificates related to the Fixed Rate Group, in sequential order until
         the Certificate Principal Balance of each Class of Class A Certificates
         has been reduced to zero and in the case of the Adjustable Rate Group,
         the lesser of (x) the Principal Distribution Amount with respect to
         such Mortgage Loan Group and (y) the Class A Principal Distribution
         Amount with respect to such Mortgage Loan Group shall be distributed to
         the Owners of the Class A-6 Certificates until the Class A-6
         Certificate Principal Balance has been reduced to zero;

         Second, the lesser of (x) the excess of (i) the Principal Distribution
         Amount with respect to such Mortgage Loan Group over (ii) the amount
         distributed to the Owners of the related Class A Certificates in clause
         First above and (y) the related Class M-1 Principal Distribution Amount
         shall be distributed to the Owners of the related Class M-1
         Certificates, until the related Class M-1 Certificate Principal Balance
         has been reduced to zero;

         Third, the lesser of (x) the excess of (i) the Principal Distribution
         Amount with respect to such Mortgage Loan Group over (ii) the sum of
         the amount distributed to the Owners of the related Class A
         Certificates in clause First above and the amount distributed to the
         Owners of the related Class M-1 Certificates in clause Second above and
         (y) the related Class M-2 Principal Distribution Amount shall be
         distributed to the Owners of the related Class M-2 Certificates, until
         the related Class M-2 Certificate Principal Balance has been reduced to
         zero;


         Fourth, the lesser of (x) the excess of (i) the Principal Distribution
         Amount with respect to such Mortgage Loan Group over (ii) the sum of
         the amount distributed to the Owners of the related 

                                     S-81

<PAGE>

         Class A Certificates pursuant to clause First above, the amount
         distributed to the Owners of the related Class M-1 Certificates
         pursuant to clause Second above and the amount distributed to the
         Owners of the related Class M-2 Certificates pursuant to clause Third
         above and (y) the related Class B Principal Distribution Amount with
         respect to such Mortgage Loan Group shall be distributed to the Owners
         of the related Class B Certificates, until the related Class B
         Certificate Principal Balance has been reduced to zero;

         Fifth, the lesser of (x) any amount of the Principal Distribution
         Amount with respect to such Mortgage Loan Group remaining after making
         all of the distributions in clauses First, Second, Third, Fourth and
         Fifth above and (b) the positive difference, if any, of (i) with
         respect to the Fixed Rate Group (A) $1,700,000 minus (B) the Target
         Overcollateralization Amount for the Fixed Rate Group for such Payment
         Date or (ii) with respect to the Adjustable Rate Group (A) $1,050,000
         minus (B) the Target Overcollateralization Amount for the Adjustable
         Rate Group for such Payment Date shall be applied as a payment of
         principal with respect to the related Subordinate Certificates in
         reverse order of seniority (i.e., first to the related Class B
         Certificates, second to the related Class M-2 Certificates, third to
         the related Class M-1 Certificates and fourth to the related Class A
         Certificates) until their respective Certificate Principal Balances
         have been reduced to zero; and

         Sixth, any amount of the Principal Distribution Amount with respect to
         such Mortgage Loan Group remaining after making all of the
         distributions in clauses First, Second, Third, Fourth and Fifth above
         shall be distributed as part of the Monthly Excess Cashflow Amount with
         respect to such Mortgage Loan Group and shall be applied as described
         below under "Credit Enhancement--Application of Monthly Excess Cashflow
         Amounts."

         Notwithstanding the foregoing, in the event that the Certificate
         Principal Balance of all of the Class A Certificates relating to a
         Mortgage Loan Group have been reduced to zero, all amounts of principal
         that would have been distributed to such Class A Certificates will be
         distributed to the related Subordinate Certificates of such Group
         sequentially in the following order: first, to the related Class M-1
         Certificates, second, to the related Class M-2 Certificates and third,
         to the related Class B Certificates. Similarly, if the Certificate
         Principal Balance of the Class M-1 Certificates has been reduced to
         zero, all amounts of principal that would have been distributed to such
         Class M-1 Certificates will be distributed to the related Class M-2 and
         Class B Certificates in that order. Finally, if the Certificate
         Principal Balance of the Class M-2 Certificates has been reduced to

         zero, all amounts of principal that would have been distributed on such
         Class M-2 Certificates will be distributed to the related Class B
         Certificates.

         The Class A Certificates in the Fixed Rate Group (other than the Class
A-5 Certificates) are "sequential pay" classes such that the Owners of the Class
A-4 Certificate Principal Balance has been reduced to zero, the Owners of the
Class A-4 Certificates will receive no payments of principal until the Class A-3
Certificate Principal Balance has been reduced to zero, the Owners of the Class
A-3 Certificates will receive no payments of principal until the Class A-2
Certificate Principal Balance has been reduced to zero, and the Owners of the
Class A-2 Certificates will receive no payments of principal until the Class A-1
Certificate Principal Balance has been reduced to zero; provided, however, that
on any Payment Date on which the sum of the Certificate Principal Balance of the
Subordinate Certificates in the Fixed Rate Group and the Overcollateralization
Amount relating to the Fixed Rate Group is zero, any amounts of principal
payable to the Owners of the Class A Certificates in the Fixed Rate Group on
such Payment Date shall be distributed pro rata and not sequentially.

Calculation of LIBOR

         On the second business day preceding each Payment Date or, in the case
of the first Payment Date, on the second business day preceding the Closing Date
(each such date, an "Interest Determination Date"), the Trustee will determine
the London interbank offered rate for one-month U.S. dollar deposits ("LIBOR")
for the next Accrual Period for the Adjustable Rate Group Certificates on the
basis of the offered rates of the Reference Banks for one-month U.S. dollar
deposits, as such rates appear on the Reuters Screen LIBO Page, as of 11:00 a.m.
(London time) on such Interest Determination Date. As used in this section,
"business day" means a day on which banks are open for dealing in foreign
currency and exchange in London and New York City; "Reuters Screen LIBO page"
means the display designated as page "LIBO" on the Reuter Monitor Money Rates
Service (or such other page as may replace the LIBO page on that service for the
purpose of displaying London interbank offered rates of major banks); and
"Reference Banks" means leading banks selected as the Trustee and engaged in
transactions in Eurodollar deposits in the international Eurocurrency market (i)
with an established place of business in London, (ii) whose quotations appear on
the Reuters Screen LIBO Page on the Interest Determination Date in question,
(iii) which have been designated as such by the Trustee and (iv) not
controlling, controlled by, or be under common control with, the Sponsor.

         On each Interest Determination Date, LIBOR for the related Accrual
Period for the Adjustable Rate Group Certificates will be established by the
Trustee as follows:

         (a) If on such Interest Determination Date two or more Reference Banks
provides such offered quotations, LIBOR for the related Accrual Period for the
Adjustable Rate Group Certificates shall be the arithmetic mean of such offered
quotations (rounded upwards if necessary to the nearest whole multiple of

1/16%).

         (b) If on such Interest Determination Date fewer than two Reference
Banks provide such offered quotations, LIBOR for the related Accrual Period for
the Adjustable Rate Group Certificates shall be the higher of (x) LIBOR as
determined on the previous Interest Determination Date and (y) the Reserve
Interest Rate. The "Reserve Interest Rate" shall be the rate per annum that the
Trustee determines to be either (i) the arithmetic mean (rounded upwards if
necessary to the nearest whole multiple of 1/16%) of the one-month U.S. dollar
lending rates which New York City banks selected by the Trustee are quoting on
the relevant Interest Determination Date to the principal London offices of
leading banks in the London interbank market or, in the event that the Trustee
can determine no such arithmetic mean, (ii) the lowest one-month U.S. dollar
lending rate which New York City banks selected by the Trustee are quoting on
such Interest Determination Date to leading European banks.

         The establishment of LIBOR on each Interest Determination Date by the
Trustee and the Trustee's calculation of the rate of interest applicable to the
Adjustable Rate Group Certificates for the related Accrual Period shall (in the
absence of manifest error) be final and binding. Each such rate of interest may
be obtained by telephoning the Trustee at 1-800-735-7777.

Certain Activities

         The Trust has not and will not: (i) issue securities (except for the
Certificates); (ii) borrow money; (iii) make loans; (iv) invest in securities
for the purpose of exercising control; (v) underwrite securities; (vi) except as
provided in the Pooling and Servicing Agreement, engage in the purchase and sale
(or turnover) of investments; (vii) offer securities in exchange for property
(except Certificates for the Mortgage Loans); or (viii) repurchase or otherwise
reacquire its securities. See "Description of the Securities -- Reports To The
Securityholders" in the Prospectus for information regarding reports to the
Owners.

                              CREDIT ENHANCEMENT

         The Credit Enhancement provided for the benefit of the Owners of the
Class A Certificates consists of the subordination of the related Subordinate
Certificates, the priority of application of Realized Losses, the application of
Monthly Excess Cashflow Amounts and the crosscollateralization feature of the
Trust.

Subordination of Subordinate Certificates

         The rights of the Owners of the Subordinate Certificates and the
Retained Certificates to receive distributions with respect to the Mortgage
Loans in a particular Mortgage Loan Group will be subordinated, to the extent
described herein, to such rights of the Owners of the Class A Certificates
related to such Mortgage Loan Group. This subordination is intended to enhance
the likelihood of regular receipt by the Owners of the Class A Certificates of

the full amount of their scheduled monthly payment of interest and principal and
to afford such Owners protection against Realized Losses allocated against such
Mortgage Loan Group.

         In addition, the rights of the Owners of the Class M-2, Class B and
Class R Certificates issued with respect to a Mortgage Loan Group to receive
distributions will be subordinated, to the extent described herein, to such
rights of the Owners of the Class A and Class M-1 Certificates. This
subordination is intended to enhance the likelihood of regular receipt by the
Owners of the related Class A and Class M-1 Certificates of the amount of
interest due them and principal available for distribution and to afford such
Owners with protection against Realized Losses.

         The rights of the Owners of the Class B and Class R Certificates to
receive distributions will be subordinated in the same manner to such rights of
the Owners of the related Class A, Class M-1 and Class M-2 Certificates and the
rights of Owners of the related Class R Certificates to receive distributions
will be subordinated in the same manner to such rights of the Owners of the
Offered Certificates.

Application of Realized Losses

         The Pooling and Servicing Agreement provides that if a Mortgage Loan
becomes a Liquidated Loan during a Remittance Period, the Net Liquidation
Proceeds relating thereto and allocated to principal may be less than the
Principal Balance of such Mortgage Loan. The amount of such insufficiency is a
Realized Loss. Realized Losses which occur in a Mortgage Loan Group will, in
effect, be absorbed first, by the related Retained Certificates (both through
the application of the Monthly Excess Interest Amount to fund such deficiency
and through a reduction in the related Overcollateralization Amount), second, by
the Owners of the related Class B Certificates, third, by the Owners of the
related Class M-2 Certificates, and, fourth, by the Owners of the related Class
M-1 Certificates.

         To the extent that a Mortgage Loan Group experiences Realized Losses,
such Realized Losses will reduce the aggregate outstanding Principal Balance of
the Mortgage Loans in such Mortgage Loan Group (i.e., a reduction in the
collateral balance will occur). Since the Overcollateralization Amount with
respect to a Mortgage Loan Group is the excess, if any, of the related
collateral balance over the related Aggregate Certificate Principal Balance,
Realized Losses, to the extent experienced, will in the first instance reduce
the related Overcollateralization Amount.

         The Pooling and Servicing Agreement requires that the
Overcollateralization Amount with respect to a Mortgage Loan Group be initially
increased to, and thereafter maintained at, the related Targeted
Overcollateralization Amount. This increase and subsequent maintenance is
intended to be accomplished 

                                     S-84

<PAGE>

by the application of related Monthly Excess Interest Amounts to the funding of

the related Extra Principal Distribution Amount. Such Extra Principal
Distribution Amounts, since they are funded from interest collections on the
Collateral but are distributed as principal on the Offered Certificates, will
increase the related Overcollateralization Amount.

         If, on any Payment Date after taking into account all Realized Losses
experienced during the prior Remittance Period and after taking into account the
distribution of principal (including, the Extra Principal Distribution Amount)
with respect to the related Offered Certificates on such Payment Date, the
Aggregate Certificate Principal Balance with respect to a Mortgage Loan Group
exceeds the aggregate Principal Balance of the Mortgage Loans in such Mortgage
Loan Group as of the end of the related Remittance Period (i.e., if the level of
overcollateralization is negative), then the Certificate Principal Balance of
the related Subordinate Certificates will be reduced (in effect, "written down")
such that the level of overcollateralization is zero, rather than negative. Such
a negative level of overcollateralization is an Applied Realized Loss Amount,
which will be applied as a reduction in the Certificate Principal Balance of the
related Subordinate Certificates in reverse order of seniority (i.e., first
against the Class B Certificate Principal Balance until it is reduced to zero,
then against the Class M-2 Certificate Balance until it is reduced to zero and
then against the Class M-1 Certificate Principal Balance until it is reduced to
zero). The Pooling and Servicing Agreement does not permit the "write down" of
the Certificate Principal Balance of any Class A Certificate.

         Once the Certificate Principal Balance of a Class of Subordinate
Certificates has been "written down," the amount of such write down will no
longer bear interest, nor will such amount thereafter be "reinstated" or
"written up," although the amount of such write down may, on future Payment
Dates be paid to Owners of the Subordinate Certificates which experienced the
write down, in direct order of seniority (i.e., first, the Class M-1
Certificates, second, the Class M-2 Certificates and, third, the Class B
Certificates). The source of funding of such payments will be the amount, if
any, of the Monthly Excess Cashflow Amount remaining on such future Payment
Dates after the funding of the Extra Principal Distribution Amount and after the
payment of Interest Carry Forward Amounts with respect to the related
Subordinate Certificates on such Payment Date.

Application of Monthly Excess Cashflow Amounts

         The weighted average net Coupon Rate for the Mortgage Loans in each
Mortgage Loan Group is generally expected to be higher than the weighted average
of the Pass-Through Rates on the Offered Certificates related to such Mortgage
Loan Group, thus generating certain excess interest collections which, in the
absence of losses will not be necessary to fund interest distributions on the
Offered Certificates. The Pooling and Servicing Agreement provides that this
excess interest be applied to the extent available, to make accelerated payments
of principal (i.e., the Extra Principal Distribution Amount) to the Class or
Classes then entitled to receive distributions of principal; such application
will cause the Aggregate Certificate Principal Balance with respect to a
Mortgage Loan Group to amortize more rapidly than the Mortgage Loans in such
Mortgage Loan Group, resulting in overcollateralization. This excess interest
for a Remittance Period and with respect to a Mortgage Loan Group, together with
interest on the related Overcollateralization Amount itself, on the related
Payment Date is the Monthly Excess Interest Amount for such Payment Date and

Mortgage Loan Group.

         The required level of overcollateralization for any Mortgage Loan Group
and Payment Date is the Targeted Overcollateralization Amount for such Mortgage
Loan Group and Payment Date. The Targeted Overcollateralization Amount is
initially, (i.e., prior to the related Stepdown Date) $9,010,000 with respect to
the Fixed Rate Group and $8,400,000 with respect to the Adjustable Rate Group.
Since the actual level of the Overcollateralization Amount with respect to each
Mortgage Loan Group as of the Closing Date is less than the related Targeted
Overcollateralization Amount, in the early months of the transaction, 

                                     S-85

<PAGE>

subject to the availability of Monthly Excess Interest Amounts, Extra Principal
Distribution Amounts will be paid, with the result that the
Overcollateralization Amount with respect to each Mortgage Loan Group will
increase to the level of the related Targeted Overcollateralization Amount.

         If, once the Targeted Overcollateralization Amount with respect to each
Mortgage Loan Group has been reached, Realized Losses occur in such Mortgage
Loan Group, such Realized Losses will result in an Overcollateralization
Deficiency (since such Realized Losses reduce the Principal Balance of the
related Mortgage Loans without giving rise to a corresponding reduction of the
related Aggregate Certificate Principal Balance). The cashflow priorities of the
Trust require that, in this situation, an Extra Principal Distribution Amount be
paid (subject to the availability of any Monthly Excess Interest Amount) for the
purpose of re-establishing the Overcollateralization Amount at the then-required
Targeted Overcollateralization Amount.

         On and after the Stepdown Date, the Targeted Overcollateralization
Amount with respect to the Fixed Rate Group and the Adjustable Rate Group,
respectively, is permitted to decrease or "step-down" below the $9,010,000 and
$8,400,000 levels to levels equal to 5.3% and 8.0% of the then current aggregate
outstanding Principal Balance of the related Mortgage Loan Group (subject to a
floor of $1,700,000 and $1,050,000, respectively). If the Targeted
Overcollateralization Amount with respect to each Mortgage Loan Group is
permitted to "step-down" on a Payment Date, the Pooling and Servicing Agreement
permits a portion of the related Principal Remittance Amount for such Payment
Date not to be passed through as a distribution of principal on such Payment
Date. This has the effect of decelerating the amortization of the Offered
Certificates with respect to each Mortgage Loan Group relative to the aggregate
outstanding Principal Balance of the Mortgage Loans, thereby reducing the actual
level of the related Overcollateralization Amount to the new, lower Targeted
Overcollateralization Amount. This portion of the Principal Remittance Amount
not distributed as principal on the related Certificates therefore releases
overcollateralization from the Trust with respect to the related Mortgage Loan
Group. The amount of such releases are the Overcollateralization Release
Amounts.

         On any Payment Date, the sum of the Monthly Excess Interest Amount and
the Overcollateralization Release Amount with respect to a Mortgage Loan Group
is the Monthly Excess Cashflow Amount, which is required to be applied in the

following order of priority on such Payment Date.

         (1)      to fund the Class A Interest Carry Forward Amount, if any, 
                  with respect to the related Mortgage Loan Group;

         (2)      to fund the Extra Principal Distribution Amount for such 
                  Payment Date with respect to the related Mortgage Loan Group;

                  with respect to the related Mortgage Loan Group;

         (4)      to fund the Class M-1 Realized Loss Amortization Amount for

                  Payment Date, with respect to the related Mortgage Loan Group;

         (9)      to fund any amounts listed in clauses (1) through (8) above
                  for such Payment Date with respect to the other Mortgage Loan
                  Group to the extent that such amounts have not been funded in
                  full through the application of such Mortgage Loan Group's
                  Monthly Excess Cashflow Amount on such Payment Date; and

         (10)     to the Servicer to the extent of any unreimbursed Delinquency
                  Advances or Servicing Advances including nonrecoverable 
                  Delinquency Advances and nonrecoverable Servicing Advances; 
                  and

         (11)     to make payment of any Supplemental Interest Amount then due,
                  or otherwise, to fund a distribution to the Owners of the
                  Class R Certificates.

                     THE POOLING AND SERVICING AGREEMENT

         In addition to the provisions of the Pooling and Servicing Agreement
summarized elsewhere in this Prospectus Supplement and the Prospectus, there is
set forth below a summary of certain other provisions of the Pooling and
Servicing Agreement.

Formation of the Trust

         The Trust will be created and established pursuant to the Pooling and
Servicing Agreement on the Closing Date. On such date, the Sponsor will cause
the Trust to acquire the Mortgage Loans, and the Trust will issue the Offered
Certificates to the Owners thereof.

                                     S-88

<PAGE>

         The property of the Trust shall include all money, instruments and
other property to the extent such money, instruments and other property are
subject or intended to be held in trust for the benefit of the Owners, and all
proceeds thereof, including, without limitation, (i) the Mortgage Loans, (ii)

such amounts, including Eligible Investments, as from time to time may be held
by the Trustee in the Distribution Account and by the Master Servicer in the
Principal and Interest Account (except as otherwise provided in the Pooling and
Servicing Agreement), each to be created pursuant to the Pooling and Servicing
Agreement, (iii) any Mortgaged Property, the ownership of which has been
effected on behalf of the Trust as a result of foreclosure or acceptance by the
Master Servicer of a deed in lieu of foreclosure and that has not been withdrawn
from the Trust, (iv) any insurance policies relating to the Mortgage Loans and
any rights of the Sponsor or the affiliated Originators under any insurance
policies, and (v) Net Liquidation Proceeds with respect to any Liquidated Loan
(collectively, the "Trust Estate").

Sale of Mortgage Loans

         Not later than the Closing Date the Sponsor will cause the Originators
to transfer the Mortgage Loans pursuant to one or more Master Mortgage Loan
Transfer Agreements between the Originators and the Sponsor (the "Master
Transfer Agreements"). In the Master Transfer Agreements the Originators will
make certain representations and warranties; the Sponsor will assign its rights
to enforce such representations and warranties to the Trustee.

         Pursuant to the Pooling and Servicing Agreement, the Sponsor on the
Closing Date will cause the Trust to acquire all right, title and interest of
the Originators in each Mortgage Loan listed on the schedule delivered to the
Trustee on the Closing Date (the "Schedule of Mortgage Loans") and all their
right, title and interest in all principal collected and all interest due on
each such Mortgage Loan on or after the Cut-Off Date.

         In connection with the sale of the Mortgage Loans on the Closing Date,
the Originators will be required to deliver to the Trustee a file (a "Mortgage
Loan File") consisting of, among other things, (i) the original Notes or
certified copies thereof, endorsed by the Originator thereof in blank or to the
order of the holder, (ii) originals of all intervening assignments, showing a
complete chain of title from origination to the applicable Originators, if any,
including warehousing assignments, with evidence of recording thereon, (iii)
originals of all assumption and modification agreements if any, and, unless such
Mortgage Loan is covered by a counsel's opinion as described in the next
paragraph, (iv) either: (a) the original Mortgage, with evidence of recording
thereon, (b) a true and accurate copy of the Mortgage where the original has
been transmitted for recording, until such time as the original is returned by
the public recording office or (c) a copy of the Mortgage certified by the
public recording office in those instances where the original recorded Mortgage
has been lost. The Trustee will agree, for the benefit of the Owners, to review
each such file within 90 days after the Closing Date to ascertain that all
required documents (or certified copies of documents) have been executed and
received.

         The Originators are additionally required to cause to be prepared and
recorded, within 75 business days of the Closing Date (or, if original recording
information is unavailable, within such later period as is permitted by the
Pooling and Servicing Agreement) assignments of the Mortgages from the
Originators to the Trustee, in the appropriate jurisdictions in which such
recordation is necessary to perfect the lien thereof as against creditors of or
purchasers from the Originators; provided, however, that such requirements may

be waived to the extent that the Sponsor delivers to the Trustee an acceptable
opinion of counsel to the effect that the preparation and recordation of such
assignments in certain jurisdictions is not necessary to protect the Trust's
interest in the related Mortgage Loans.

liquidation, as contemplated by Section 860F(a)(4) of the Code and (ii) to
furnish to the Trustee an opinion of counsel experienced in federal income tax
matters acceptable to the Trustee to the effect that such liquidation
constitutes a Qualified Liquidation.

Optional Termination

         By the Master Servicer. At its option, the Master Servicer acting
directly or through one or more affiliates may determine to purchase from the
Trust all of the Mortgage Loans and other property then held by the Trust, and
thereby effect early retirement of the Offered Certificates, on any Remittance
Date on and after the Clean-up Call Date.

         Termination Upon Loss of REMIC Status. Following a final determination
by the Internal Revenue Service or by a court of competent jurisdiction, in
either case from which no appeal is taken within the permitted time for such
appeal, or if any appeal is taken, following a final determination of such
appeal from which no further appeal can be taken, to the effect that the Trust
does not and will no longer qualify as a "REMIC" pursuant to Section 860D of the
Code (the "Final Determination"), at any time on or after the date which is 30
calendar days following such Final Determination, the Owners of a majority in

Percentage Interests represented by the Offered Certificates then Outstanding
may direct the Trustee on behalf of the Trust to adopt a plan of complete
liquidation, as contemplated by Section 860F(a)(4) of the Code.

                   CERTAIN FEDERAL INCOME TAX CONSEQUENCES

         The following discussion of certain of the material anticipated federal
income tax consequences of the purchase, ownership and disposition of the
Offered Certificates is to be considered only in connection with "Certain
Federal Income Tax Consequences" in the Prospectus. The discussion herein and in
the Prospectus is based upon laws, regulations, rulings and decisions now in
effect, all of which are subject to change. The discussion below and in the
Prospectus does not purport to deal with all federal tax consequences applicable
to all categories of investors, some of which may be subject to special rules.
Investors should consult their own tax advisors in determining the federal,
state, local and any other tax consequences to them of the purchase, ownership
and disposition of the Offered Certificates.

REMIC Elections

         The Trustee will cause one or more REMIC elections to be made with
respect to certain specified assets of the Trust for federal income tax
purposes. Qualification as a REMIC requires ongoing compliance with certain
conditions. Dewey Ballantine, special tax counsel, will advise that, in its
opinion, for federal income tax purposes, assuming the REMIC elections are made
and compliance with the Pooling and Servicing Agreement, the Trust will be
treated as a REMIC for federal income tax purposes. Each of the Fixed Rate Group
Certificates will be a "regular interest" in a REMIC, which will be treated as a
debt instrument of the Trust for federal income tax purposes. Each of the
Adjustable Rate Certificates and the related rights to receive Supplemental
Interest Payments will be comprised of (i) a "regular interest" in a REMIC and
(ii) the right to receive Supplemental Interest Payments having the
characteristics described below.

         For federal income tax purposes, regular interests in a REMIC are
treated as debt instruments issued by the REMIC on the date on which those
interests are created, and not as ownership interests in the REMIC or its
assets. Owners of Offered Certificates that otherwise report income under a cash

                                     S-92

method of accounting will be required to report income with respect to such
Offered Certificates under an accrual method. The Offered Certificates may be
issued with "original issue discount" for federal income tax purposes. The
prepayment assumption that will be used in determining the rate of accrual of
original issue discount on the Offered Certificates is 100% of the "Prepayment
Assumption". See "Payment and Yield Considerations -- Projected Prepayments and
Yields for Offered Certificates" herein. No representation is made that any of
the Mortgage Loans will prepay at such rates or any other rate. See "Payment and
Yield Considerations -- Projected Prepayments and Yields for Offered
Certificates" herein and "Certain Federal Income Tax Consequences -- Discount
and Premium" in the Prospectus.


Special Tax Attributes

         The Offered Certificates possess certain special tax attributes by
virtue of the REMIC provisions of the Code. See "Certain Federal Income Tax
Consequences -- REMIC Securities -- Special Tax Attributes" in the Prospectus.
The Small Business Job Protection Act of 1996 repeals the bad debt reserve
method of accounting for mutual savings banks and domestic building and loan
associations for tax years beginning after December 31, 1995. As a result,
Section 593(d) of the Code is no longer applicable to treat REMIC regular
interests, including the Certificates, as "qualifying real property loans."

Supplemental Interest Amounts

         The Beneficial Owners of the Adjustable Rate Group Certificates and the
related rights to receive Supplemental Interest Amounts will be treated for tax
purposes as owning two separate investments: (i) the respective Adjustable Rate
Group Certificates without the right to receive Supplemental Interest Amounts
and (ii) the right to receive the Supplemental Interest Amounts. The Owners of
the respective Adjustable Rate Group Certificates must allocate the purchase
price of their Certificates between these two investments based on their
relative fair market values. The purchase price allocated to the first
investment will be the issue price of the respective Adjustable Rate Group
Certificates for calculating accruals of original issue discount. See "Certain
Federal Income Tax Consequences -- Discount and Premium" in the Prospectus.

         A Beneficial Owner of an Adjustable Rate Group Certificate and the
related rights to receive Supplemental Interest Amounts will be treated for
federal income tax purposes as having entered into a notional principal contract
on the date that it purchases its Certificate. Treasury Regulations under
Section 446 of the Code relating to notional principal contracts (the "Notional
Principal Contract Regulations") provide that taxpayers, regardless of their
method of accounting, generally must recognize the ratable daily portion of a
periodic payment for the taxable year to which that portion relates. Any
Supplemental Interest Amounts will be periodic payments. Income with respect to
periodic payments under a notional principal contract for a taxable year should
constitute ordinary income. The purchase price allocated to the right to receive
the related Supplemental Interest Amounts will be treated as a nonperiodic
payment under the Notional Principal Contract Regulations. Such a nonperiodic
payment may be amortized using several methods, including the level payment
method described in the Notional Principal Contract Regulations.

         The right to receive the Supplemental Interest Amounts will not
constitute: (i) a "real estate asset" within the meaning of section 858(c)(5)(A)
of the Internal Revenue Code (the "Code") if held by a real estate investment
trust; (ii) a "qualified mortgage" within the meaning of section 860G(a)(3) of
the Code or a "permitted investment" within the meaning of section 860G(a)(5) of
the code if held by a REMIC; or (iii) assets described in section
7701(a)(19)(C)(xi) of the Code if held by a thrift. Moreover, other special
rules may apply to certain investors, including dealers in securities and
dealers in notional principal contracts.

         Taxation of Foreign Investors

         In general, foreign investors will not be subject to U.S. withholding
on income from the Supplemental Interest Amounts. See "Certain Federal Income
Tax Consequences -- Foreign Investors -- Grantor Trust Securities and REMIC
Regular Securities" in the Prospectus.

                             ERISA CONSIDERATIONS

Class A Certificates

         Section 406 of ERISA and Section 4975 of the Code prohibit a pension,
profit sharing or other employee benefit plan (the "Plans") from engaging in
certain transactions involving "plan assets" with persons that are "parties in
interest" under ERISA or "disqualified persons" under the Code with respect to
the Plan unless a statutory or administrative exemption applies to the
transaction. ERISA also imposes certain duties on persons who are fiduciaries of
Plans subject to ERISA. A violation of these "prohibited transaction" rules may
generate excise tax and other liabilities under ERISA and the Code for such
persons. In addition, investments by Plans are subject to ERISA's general
fiduciary requirements, including the requirement of investment prudence and
diversification and the requirement that a Plan's investments be made in
accordance with the documents governing the Plan.

         The United States Department of Labor (the "DOL") has issued a
regulation (the "Plan Asset Regulation") describing what constitutes the assets
of a Plan when the Plan acquires an equity interest in another entity. The Plan
Asset Regulation states that, unless an exception described in the regulation is
applicable, the underlying assets of a corporation, partnership or trust in
which a Plan makes an equity investment will be considered, for purposes of
ERISA, to be assets of the investing Plan. Pursuant to the Plan Asset
Regulation, if the assets of the Trust were deemed to be plan assets by reason
of a Plan's investment in any Offered Certificates, such plan assets would
include an undivided interest in any assets held in such Trust. Therefore, in
the absence of an exemption, the purchase, sale or holding of any Offered
Certificate by a Plan (including certain individual retirement arrangements)
subject to Section 406 of ERISA or Section 4975 of the Code might result in
prohibited transactions and the imposition of excise taxes and civil penalties.

         The DOL has issued to the Underwriters individual prohibited
transaction exemptions, (the "Exemptions"), which generally exempt from the
application of the prohibited transaction provisions of Section 406(a), Section
406(b)(1), Section 406(b)(2) and Section 407(a) of ERISA and the excise taxes
imposed pursuant to Sections 4975(a) and (b) of the Code, certain transactions
with respect to the initial purchase, the holding and the subsequent resale by
Plans of certificates in pass-through trusts that consist of certain
receivables, loans and other obligations that meet the conditions and
requirements of the Exemptions. The loans covered by the Exemptions include
mortgage loans such as the Mortgage Loans.

         Among the conditions that must be satisfied for the Exemptions to apply
are the following:


         (1) the acquisition of the certificates by a Plan is 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;

         (2) the rights and interests evidenced by the certificates acquired by
the Plan are not subordinated to the rights and interests evidenced by other
certificates of the trust;

                                     S-94

<PAGE>

         (3) the certificates acquired by the Plan have received a rating at the
time of such acquisition that is one of the three highest generic rating
categories from either Standard & Poor's, Moody's, Duff & Phelps Credit Rating
Co. ("D&P") or Fitch;

         (4) the Trustee is not an affiliate of any other member of the 
Restricted Group (as defined below);

         (5) the sum of all payments made to and retained by the Underwriters in
connection with the distribution of the certificates represents not more than
reasonable compensation for underwriting the certificates; the sum of all
payments made to and retained by the Originator and the Sponsor pursuant to the
assignment of the loans to the Trust Estate represents not more than the fair
market value of such loans; the sum of all payments made to and retained by any
Servicer represents not more than reasonable compensation for such person's
services under the Pooling and Servicing Agreement and reimbursement of such
person's reasonable expenses in connection therewith; and

         (6) the Plan investing in the certificates is an "accredited investor"
as defined in Rule 501(a)(1) of Regulation D of the Commission under the
Securities Act of 1933.

         The Trust Estate must also meet the following requirements:

         (i) the corpus of the Trust Estate must consist solely of assets of the
type that have been included in other investment pools;

         (ii) certificates in such other investment pools must have been rated
in one of the three highest rating categories of Standard & Poor's, Moody's,
Fitch or D&P for at least one year prior to the Plan's acquisition of
certificates; and

         (iii) certificates evidencing interests in such other investment pools
must have been purchased by investors other than Plans for at least one year
prior to the Plan's acquisition of certificates.

         Moreover, the Exemptions provide relief from certain
self-dealing/conflict of interest prohibited transactions that may occur when
the Plan fiduciary causes a Plan to acquire certificates in a trust in which the
fiduciary (or its affiliate) is an obligor on the receivables held in the trust;
provided that, among other requirements, (i) in the case of an acquisition in

connection with the initial issuance of certificates, at least fifty percent of
each class of certificates in which Plans have invested is acquired by persons
independent of the Restricted Group and at least fifty percent of the aggregate
interest in the trust is acquired by persons independent of the Restricted
Group; (ii) such fiduciary (or its affiliate) is an obligor with respect to five
percent or less of the fair market value of the obligations contained in the
trust; (iii) the Plan's investment in certificates of any class does not exceed
twenty-five percent of all of the certificates of that class outstanding at the
time of the acquisition; and (iv) immediately after the acquisition, no more
than twenty-five percent of the assets of the Plan with respect to which such
person is a fiduciary are invested in certificates representing an interest in
one or more trusts containing assets sold or serviced by the same entity. The
Exemptions do not apply to Plans sponsored by the Sponsor, the Underwriters, the
Trustee, the Master Servicer, any other servicer, any obligor with respect to
Mortgage Loans included in the Trust Estate constituting more than five percent
of the aggregate unamortized principal balance of the assets in the Trust
Estate, or any affiliate of such parties (the "Restricted Group").

         As of the date hereof, there is no single Mortgage Loan included in the
Trust Estate that constitutes more than five percent of the aggregate
unamortized principal balance of the assets of the Trust Estate. Before
purchasing a Class A Certificate based on the Exemptions (and, in the case of
the Class A-6 Certificates, an administrative exemption with respect to
Supplemental Interest Amounts), a fiduciary of a Plan should itself confirm (1)
that such Class A Certificate constitutes a "certificate" for purposes of 

                                     S-95

<PAGE>

the Exemptions and (2) that the conditions and other requirements set forth in
the Exemptions would be satisfied.

         Prospective Plan investors in the Class A Certificates should consult
with their legal advisors concerning the impact of ERISA and the Code, the
applicability of the Exemptions, and the potential consequences in their
specific circumstances, prior to making an investment in the Class A
Certificates. Moreover, each Plan fiduciary should determine whether under the
general fiduciary standards of investment procedure and diversification an
investment in the Class A Certificates is appropriate for the Plan, taking into
account the overall investment policy of the Plan and the composition of the
Plan's investment portfolio.

         In addition to the matters described above, purchasers of a Class A
Certificate that are insurance companies should consult with their counsel with
respect to the recent United States Supreme Court case interpreting the
fiduciary responsibility rules of ERISA, John Hancock Mutual Life Insurance Co.
v. Harris Trust and Savings Bank, 114 S.Ct. 517 (1993). In John Hancock, the
Supreme Court ruled that assets held in an insurance company's general account
may be deemed to be "plan assets" for ERISA purposes under certain
circumstances. Prospective purchasers using insurance company general account
assets should determine whether the decision affects their ability to make
purchases of the Offered Certificates.


         Any person purchasing a Class A-6 Certificate and the related right to
receive Supplemental Interest Amounts will have acquired, for purposes of ERISA
and for federal income tax purposes, such Class A-6 Certificate without the
right to receive the Supplemental Interest Amounts, together with the right to
receive the Supplemental Interest Amounts. The Exemptions do not apply to the
acquisition, holding or resale of the right to receive the Supplemental Interest
Amounts. Accordingly, the acquisition of the right to receive the Supplemental
Interest Amounts by a Plan could result in a prohibited transaction unless
another administrative exemption to ERISA's prohibited transaction rules is
applicable. One or more alternative exemptions may be available with respect to
certain prohibited transaction rules of ERISA that might apply in connection
with the initial purchase, holding and resale of the right to receive the
Supplemental Interest Amounts, including, but not limited to: (i) Prohibited
Transaction Class Exemption ("PTCE") 91-38, regarding investments by bank
collective investment funds; (ii) PTCE 90-1, regarding investments by insurance
company pooled separate accounts; (iii) PTCE 84-14, regarding transactions
negotiated by qualified professional asset managers; or (iv) PTCE 75-1, Part II,
regarding principal transactions by broker-dealers (the "Principal Transactions
Exemption"). It is believed that the conditions of the Principal Transactions
Exemption will be met with respect to the acquisition of a right to receive the
Supplemental Interest Amounts by a Plan, so long as the related Underwriter is
not a fiduciary with respect to the Plan (and is not a party in interest with
respect to the Plan by reason of being a participating employer or affiliate
thereof).

Subordinate Certificates

         The Exemptions do not apply to the initial purchase, the holding or the
subsequent resale of the Mezzanine Certificates and Class B Certificates because
such Certificates are subordinate to certain other Classes of the Certificates.
Accordingly, Plans may not purchase the Mezzanine Certificates or Class B
Certificates, except that any insurance company may purchase such Certificates
with assets of its general account if the exemptive relief granted by the DOL
for transactions involving insurance company general accounts in Prohibited
Transaction Exemption 95-60, 60 Fed. Reg. 35925 (July 12, 1995) is available
with respect to such investment. Any insurance company proposing to purchase
such Certificates for its general account should consider whether such relief
would be available.

                                   RATINGS

         It is a condition of issuance of the Offered Certificates that each 
Class of the Offered Certificates receive ratings from Moody's Investors
Service, Inc. ("Moody's") and Fitch Investors Service, L.P. ("Fitch") as set 
forth below:

   Class                              Moody's Rating             Fitch Rating
   -----                              --------------             ------------
   Class A                            Aaa                        AAA
   Class M-1F                         Aa2                        AA+

   Class M-2F                         A2                         A+
   Class B-1F                         Baa2                       BBB+
   Class M-1A                         Aa2                        AA+
   Class M-2A                         A1                         A+
   Class B-1A                         Baa2                       BBB+

         Explanations of the significance of such ratings may be obtained from
Moody's, 99 Church Street, New York, New York 10007 and Fitch, One State Street
Plaza, 33rd Floor, New York, New York 10004. Such ratings will be the views only
of such rating agencies. There is no assurance that such ratings will continue
for any period of time or that such ratings will not be revised or withdrawn.
Any such revision or withdrawal of such ratings may have an adverse effect on
the market price of the Offered Certificates. A security rating is not a
recommendation to buy, sell or hold securities.

         The ratings do not address the likelihood of the payment of
Supplemental Interest Amounts.

         The ratings assigned by Fitch to pass-through certificates address the
likelihood of the receipt by the Owners of all distributions to which such
Owners are entitled. The ratings assigned by Fitch to pass-through certificates
address the likelihood of the receipt by the Owners of all distributions (other
than the payment of Supplemental Interest Amounts) to which such Owners are
entitled. Fitch's ratings address the structural and legal aspects associated
with the Certificates, including the nature of the underlying loans and the
credit quality of the credit support provider. Fitch's ratings on home equity
pass-through Certificates do not represent any assessment of the likelihood or
rate of principal prepayments. The ratings do not address the possibility that
Owners might suffer a lower than anticipated yield.

         The ratings of Moody's on home equity pass-through certificates address
the likelihood of the receipt by the Owners of all distributions to which such
Owners are entitled. Moody's rating opinions address the structural and legal
issues and tax-related aspects associated with the Certificates, including the
nature of the underlying home equity loans and the credit quality of the credit
support provider, if any. Moody's ratings on pass-through certificates do not
represent any assessment of the likelihood that principal prepayments may differ
from those originally anticipated.

         The ratings of Moody's and Fitch do not address the possibility that,
as a result of principal prepayments, certificateholders may receive a lower
than anticipated yield.

         The ratings of the Certificates should be evaluated independently from
similar ratings on other types of securities. A security rating is not a
recommendation to buy, sell or hold securities and may be subject to revision or
withdrawal at any time by the assigning rating agency.

         The Sponsor has not requested a rating of the Offered Certificates
offered hereby by any rating agency other than Moody's and Fitch and the Sponsor
has not provided information relating to the Offered 

                                     S-97


<PAGE>

Certificates or the Mortgage Loans to any rating agency other than Moody's and
Fitch. However, there can be no assurance as to whether any other rating agency
will rate the Offered Certificates offered hereby or, if another rating agency
rates such Offered Certificates, what rating would be assigned to such Offered
Certificates by such rating agency. Any such unsolicited rating assigned by
another rating agency to the Offered Certificates offered hereby may be lower
than the rating assigned to such Offered Certificates by either or both of
Moody's and Fitch.

                       LEGAL INVESTMENT CONSIDERATIONS

         No class of the Offered Certificates will constitute "mortgage related
securities" for purposes of SMMEA.

                  In the Underwriting Agreement, the Underwriters have agreed,
subject to the terms and conditions set forth therein, to purchase all of the
Certificates offered hereby.

         The Underwriters have agreed to reimburse the Sponsor for certain
expenses of the issuance and distribution of the Offered Certificates.

         The Underwriters have informed the Sponsor that they propose to offer
the Offered Certificates for sale from time to time in one or more negotiated
transactions, or otherwise, at varying prices to be determined, in each case, at
the time of the related sale. The Underwriters may effect such transactions by
selling the Offered Certificates to or through dealers, and such dealers may
receive compensation in the form of underwriting discounts, concessions or
commissions from the Underwriters. In connection with the sale of the Offered
Certificates, the Underwriters may be deemed to have received compensation from
the Sponsor in the form of underwriting compensation. The Underwriters and any
dealers that participate with the Underwriters in the distribution of the
Offered Certificates may be deemed to be underwriters and any commissions

received by them and any profit on the resale of the Offered Certificates by
them may be deemed to be underwriting discounts and commissions under the
Securities Act of 1933, as amended.

         Advanta Mortgage Conduit Services, Inc. has agreed to indemnify the 
Underwriters against liabilities including liabilities under the Securities Act
of 1933, as amended.

         In connection with this offering and in compliance with applicable law
and industry practice, the Underwriters may overallot or effect transactions
which stabilize, maintain or otherwise affect the market price of the Offered
Certificates at a level above that which might otherwise prevail in the open
market, including stabilizing bids, effecting syndicate covering transactions or
imposing penalty bids. A stabilizing bid means the placing of any bid, or the
effecting of any purchase, for the purpose of pegging, fixing or maintaining the
price of a security. A syndicate covering transaction means the placing of any
bid on behalf of the underwriting syndicate or the effecting of any purchase to
reduce a short position created in connection with the offering. A penalty bid
means an arrangement that permits Morgan Stanley, as managing underwriter, to
reclaim a selling concession from a syndicate member in connection with the
offering when Offered Certificates originally sold by the syndicate member are
purchased in syndicate covering transactions. The Underwriters are not required
to engage in any of these activities. Any such activities, if commenced, may be
discontinued at any time.

         Advanta Mortgage Conduit Services, Inc. has been advised by the
Underwriters that the Underwriters presently intend to make a market in the
Offered Certificates, as permitted by applicable laws and regulations. The
Underwriters are not obligated, however, to make a market in the Offered
Certificates and such market-making may be discontinued at any time at the sole
discretion of the Underwriters. Accordingly, no assurance can be given as to the
liquidity of, or trading markets for, the Offered Certificates.

Offered Certificates will be passed upon by Dewey Ballantine, New York, New
York.

PROSPECTUS
           MORTGAGE LOAN ASSET-BACKED SECURITIES, ISSUABLE IN SERIES

[Logo]                                [Logo]
   SPONSOR OF THE TRUSTS                 MASTER SERVICER
 
     This Prospectus describes certain Mortgage Loan Asset-Backed Securities
(the "Securities") that may be issued from time to time in series and certain
classes of which may be offered hereby from time to time as described in the
related Prospectus Supplement. Each series of Securities will be issued by a
separate trust (each, a "Trust"). The primary assets of each Trust will consist
of a segregated pool (a "Mortgage Pool") of conventional one- to four-family
residential mortgage loans, multi-family residential mortgage loans, mixed use
mortgage loans, revolving home equity loans or certain balances thereof secured
by mortgages primarily on one-to-four-family residential properties, or
certificates of interest or participation therein (collectively, the "Mortgage
Loans"), to be acquired by such Trust from Advanta Mortgage Conduit Services,
Inc. (the "Sponsor"). The Sponsor will acquire the Mortgage Loans from one or
more affiliated or unaffiliated institutions (the "Originators"). In connection
with the establishment of certain Trusts the Sponsor may first transfer the
related Trust Estate to Advanta Mortgage Receivables Inc. (the "Transferor") and
the Transferor will then transfer such Trust Estate to the related Trust. The
use of the Transferor will not affect the obligations of the Sponsor with
respect to the related Trust or the related Securities. If the Transferor is to
be involved in a particular offering the related Prospectus Supplement will
describe its role in such offering; for purposes of this Prospectus the role of
the Transferor is subsumed in the role of the Sponsor. See 'The Mortgage Pools.'
 
     The Mortgage Loans in each Mortgage Pool and certain other assets described
herein and in the related Prospectus Supplement (collectively with respect to
each Trust, the "Trust Estate") and in the related Prospectus Supplement will be
held by the related Trust for the benefit of the holders of the related series
of Securities (the "Securityholders") pursuant to a Pooling and Servicing
Agreement to the extent and as more fully described herein and in the related
Prospectus Supplement. Unless otherwise specified in the related Prospectus
Supplement, each Mortgage Pool will consist of one or more of the various types
of Mortgage Loans described under "The Mortgage Pools."
                                                  (Cover continued on next page)
                            ------------------------
 
     THE ASSETS OF THE RELATED TRUST ARE THE SOLE SOURCE OF PAYMENTS ON THE
RELATED SECURITIES. THE SECURITIES DO NOT REPRESENT AN INTEREST IN OR OBLIGATION
OF THE SPONSOR, THE MASTER SERVICER, ANY ORIGINATOR OR ANY OF THEIR AFFILIATES,
EXCEPT AS SET FORTH HEREIN AND IN THE RELATED PROSPECTUS SUPPLEMENT. NEITHER THE
SECURITIES NOR THE UNDERLYING MORTGAGE LOANS WILL BE GUARANTEED OR INSURED BY
ANY GOVERNMENTAL AGENCY OR INSTRUMENTALITY OR BY THE SPONSOR, THE MASTER
SERVICER, ANY ORIGINATOR OR ANY OF THEIR AFFILIATES, EXCEPT AS SET FORTH IN THE
RELATED PROSPECTUS SUPPLEMENT. SEE ALSO 'RISK FACTORS' PAGE 13.
 
     THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES
      AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE
      SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION

          PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY 
             REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

                           ------------------------
 
     Offers of the Securities may be made through one or more different methods,
including offerings through underwriters, as more fully described under "Methods
of Distribution" and in the related Prospectus Supplement. There will be no
secondary market for any series of Securities prior to the offering thereof.
There can be no assurance that a secondary market for any of the Securities will
develop or, if it does develop, that it will offer sufficient liquidity of
investment or will continue.
 
     Retain this Prospectus for future reference. This Prospectus may not be
used to consummate sales of securities offered hereby unless accompanied by a
Prospectus Supplement.
                            ------------------------
 
                 The date of this Prospectus is March 10, 1997.

     Each series of Securities will include one or more classes. The Securities
of any particular class may represent beneficial ownership interests in the

Supplement. A series may include one or more classes of Securities entitled to
principal distributions, with disproportionate, nominal or no interest
distributions, or to interest distributions, with disproportionate, nominal or
no principal distributions. The rights of one or more classes of Securities of

OBLIGATION TO MAKE CERTAIN ADVANCES IN THE EVENT OF DELINQUENCIES IN PAYMENTS ON
THE MORTGAGE LOANS AND INTEREST SHORTFALLS DUE TO PREPAYMENT OF MORTGAGE LOANS).
SEE 'DESCRIPTION OF THE SECURITIES.'
 
     If so specified in the related Prospectus Supplement, the Trust Estate for
a series of Securities may include any combination of a mortgage pool insurance

policy, letter of credit, financial guaranty insurance policy, bankruptcy bond,
special hazard insurance policy, reserve fund or other form of Credit
Enhancement. In addition to or in lieu of the foregoing, Credit Enhancement with
respect to certain classes of Securities of any series may be provided by means
of subordination, cross-support among Mortgage Assets, as defined herein, or
over-collateralization. See 'Description of Credit Enhancement.'
 
     The rate of payment of principal of each class of Securities entitled to
principal payments will depend on the priority of payment of such class and the
rate of payment (including prepayments, defaults, liquidations and repurchases
of Mortgage Loans) of the related Mortgage Loans. A rate of principal payment
lower or higher than that anticipated may affect the yield on each class of
Securities in the manner described herein and in the related Prospectus
Supplement. The various types of Securities, the different classes of such
Securities and certain types of Mortgage Loans in a given Mortgage Pool may have
different prepayment risks and credit risks. The Prospectus Supplement for a
series of Securities or the related Current Report on Form 8-K will contain
information as to (i) types, maturities and certain statistical information
relating to credit risks of the Mortgage Loans in the related Mortgage Pool,
(ii) the effect of certain rates of prepayment, based upon certain specified
assumptions for a series of Securities and (iii) priority of payment and
maturity dates of the Securities. AN INVESTOR SHOULD CAREFULLY REVIEW THE
INFORMATION IN THE RELATED PROSPECTUS SUPPLEMENT CONCERNING THE DIFFERENT
CONSEQUENCES OF THE RISKS ASSOCIATED WITH THE DIFFERENT TYPES AND CLASSES OF
SECURITIES. See 'Yield Considerations.' A Trust may be subject to early
termination under the circumstances described herein and in the related
Prospectus Supplement.
 
     One or more separate elections may be made to treat a Trust, or one or more
segregated pools of assets held by such Trust, as a real estate mortgage
investment conduit ("REMIC") or a Financial Asset Securitization Investment
Trust ("FASIT") for federal income tax purposes. If applicable, the Prospectus
Supplement for a series of Securities will specify which class or classes of the
related series of Securities will be considered to be regular interests in a
REMIC or FASIT and which classes of Securities or other interests will be
designated as the residual interest in a REMIC or as high-yield interests or the
ownership interest in a FASIT. Alternatively, a Trust may be treated as a
grantor trust or as a partnership for federal income tax purposes, or may be
treated for federal income tax purposes as a mere security device which
constitutes a collateral arrangement for the issuance of secured debt. See
"Certain Federal Income Tax Consequences" herein.

     The following summary of certain pertinent information is qualified in its
entirety by reference to the detailed information appearing elsewhere in this
Prospectus and by reference to the information with respect to each series of
Securities contained in the Prospectus Supplement to be prepared and delivered
in connection with the offering of such series. Capitalized terms used in this
summary that are not otherwise defined shall have the meanings ascribed thereto
in this Prospectus. An index indicating where certain terms used herein are
defined appears at the end of this Prospectus.

 
Securities Offered........ Mortgage Loan Asset-Backed Securities.
Sponsor................... Advanta Mortgage Conduit Services, Inc. See "The
                             Sponsor and The Transferor."
Originators............... The Sponsor will acquire the Mortgage Loans from
                             one or more institutions affiliated with the
                             Sponsor ("Affiliated Originators") or
                             institutions unaffiliated with the Sponsor
                             ("Unaffiliated Originators") (the Affiliated
                             Originators and the Unaffiliated Originators are
                             collectively referred to as the "Originators").
                             The Sponsor will transfer the related Trust
                             Estate to the related Trust. In connection with
                             the establishment of certain Trusts the Sponsor
                             may first transfer the related Trust Estate to
                             the Transferor and the Transferor will then
                             transfer such Trust Estate to the related Trust.
                             The use of the Transferor will not affect the
                             obligations of the Sponsor with respect to the
                             related Trust or the related Securities. If the
                             Transferor is to be involved in a particular
                             offering the related Prospectus Supplement will
                             describe its role in such offering; for purposes
                             of this Prospectus the role of the Transferor is
                             subsumed in the role of the Sponsor.

                             Servicer."
Sub-Servicers............. Originators may act as Sub-Servicers for Mortgage
                             Loans acquired by the Sponsor from such
                             Originators unless all servicing duties relating
                             to such Mortgage Loans have been transferred to
                             the Master Servicer or to a third-party,
                             unaffiliated contract servicer approved by the
                             Master Servicer. See "Mortgage Loan
                             Program--Sub-Servicers." 
Trustee................... The trustee (the "Trustee") for each series of
                             Securities will be specified in the related

                             (each, a "Trust"). The primary assets of each
                             Trust will consist of a segregated pool (each, a
                             "Mortgage Pool") of conventional, one- to
                             four-family residential mortgage loans or
                             multi-family residential mortgage loans (the
                             "Mortgage Loans") or certificates of interest or
                             participation therein, acquired by such Trust
                             from the Sponsor. The Sponsor will acquire the
                             Mortgage Loans from one or more of the
                             Originators. The Securities issued by any Trust
                             may represent beneficial ownership interests in

                             the related Mortgage Loans held by the related
                             Trust, or may represent debt secured by such
                             Mortgage Loans, as described herein and in the
                             related Prospectus Supplement. Securities which
                             represent beneficial ownership interests in the
                             related

                             the related Prospectus Supplement; Securities
                             which represent debt issued by the related Trust
                             will be referred to as 'Notes' in the related
                             Prospectus Supplement.

                           Each Trust will be established pursuant to an
                             agreement (each, a 'Trust Agreement') by and
                             between the Sponsor and the Trustee named
                             therein. Each Trust Agreement will describe the
                             related pool of assets to be held in trust (each
                             such asset pool, the 'Trust Estate'), which will
                             include the related Mortgage Loans and, if so
                             specified in the related Prospectus Supplement,
                             may include any combination of a mortgage pool
                             insurance policy, letter of credit, financial
                             guaranty insurance policy, special hazard
                             policy, reserve fund or other form of Credit
                             Enhancement.

                           The Mortgage Loans held by each Trust will be
                             master serviced by the Master Servicer pursuant
                             to a servicing agreement (each, a 'Servicing
                             Agreement') by and between the Master Servicer
                             and the related Trustee.
                       
                           With respect to Securities that represent debt
                             issued by the related Trust, the related Trust
                             will enter into an indenture (each, an
                             'Indenture') by and between such Trust and the
                             trustee named on such Indenture (the 'Indenture
                             Trustee'), as set forth in the related
                             Prospectus Supplement. Securities that represent
                             beneficial ownership interests in the related
                             Trust will be issued pursuant to the related
                             Trust Agreement.
                           
                           In the case of any individual Trust, the
                             contractual arrangements relating to the
                             establishment of the Trust, the servicing of the
                             related Mortgage Loans and the issuance of the
                             related Securities may be contained in a single
                             agreement, or in several agreements which
                             combine certain aspects of the Trust Agreement,

                             the Servicing Agreement and the Indenture
                             described above (for example, a pooling and
                             servicing agreement, or a servicing and
                             collateral management agreement). For purposes
                             of this Prospectus, the term 'Pooling and
                             Servicing Agreement' as used with respect to a
                             Trust means, collectively, and except as
                             otherwise specified, any and all agreements
                             relating to the establishment of the related
                             Trust, the servicing of the related Mortgage
                             Loans and the issuance of the related Securities.

                           Securities Will Be Recourse to the Assets of the
                             Related Trust Only.

                           The sole source of payment for any series of
                             Securities will be the assets of the related
                             Trust (i.e., the related Trust Estate). The
                             Securities will not be obligations, either
                             recourse or non-recourse (except for certain
                             non-recourse debt described under 'Certain
                             Federal Income Tax Consequences'), of the
                             Sponsor, the Master Servicer, any Sub-Servicer,
                             any Originator or any Person other than the
                             related Trust. In the case of Securities that
                             represent beneficial ownership interest in the
                             related Trust Estate, such Securities will
                             represent the ownership of such Trust Estate;
                             with respect to Securities that represent debt
                             issued by the related Trust, such Securities
                             will be secured by the related Trust Estate.
                             Notwithstanding the foregoing, and as to be
                             described in the related Prospectus Supplement,
                             certain types of Credit Enhancement, such as a
                             financial guaranty insurance policy or a letter
                             of

                             obligation of the issuer of such Credit
                             Enhancement.

                           General Nature of the Securities as Investments.
                           The Securities will consist of two basic types:
                             (i) Securities of the fixed-income type
                             ('Fixed-Income Securities') and (ii) Securities
                             of the equity participation type ('Equity
                             Securities'). No Class of Equity Securities will 
                             be offered pursuant to this Prospectus or any
                             Prospectus Supplement related hereto.
                             Fixed-Income Securities will generally be styled

                             as debt instruments, having a principal balance
                             and a specified interest rate ('Interest Rate').
                             Fixed-Income Securities may be either beneficial 
                             ownership interests in the related Mortgage Loans
                             held by the related Trust, or may represent debt
                             secured by such Mortgage Loans.  Each series or
                             class of Fixed-Income Securities may have a
                             different Interest Rate, which may be a fixed or
                             adjustable Interest Rate. The related  Prospectus
                             Supplement will specify the Interest Rate for each
                             series or class of Fixed-Income Securities, or the
                             initial Interest Rate and the method for
                             determining subsequent changes to the Interest
                             Rate. 

                           A series may include one or more classes of
                             Fixed-Income Securities ('Strip Securities')
                             entitled (i) to principal distributions, with 
                             disproportionate, nominal or no interest
                             distributions, or (ii) to interest distributions,
                             with disproportionate, nominal or no principal
                             distributions. In addition, a series may include
                             two or more classes of Fixed-Income Securities that
                             differ as to timing, sequential order, priority of
                             payment, Interest Rate or amount of distributions
                             of principal or interest or both, or as to which
                             distributions of principal or interest or both
                             on any class may be made upon the occurrence of
                             specified events, in accordance with a schedule
                             or formula, or on the basis of collections from
                             designated portions of the related Mortgage
                             Pool, which series may include one or more
                             classes of Fixed-Income Securities ('Accrual
                             Securities'), as to which certain accrued interest
                             will not be distributed but rather will be added to
                             the principal balance (or nominal principal
                             balance, in the case of Accrual Securities which
                             are also Strip Securities) thereof on each Payment
                             Date, as hereinafter defined and in the manner
                             described in the related Prospectus Supplement.

                           If so provided in the related Prospectus Supplement,
                             a series of Securities may include one or more
                             other classes of Fixed-Income Securities
                             (collectively, the 'Senior Securities') that are
                             senior to one or more other classes of Fixed-Income
                             Securities (collectively, the 'Subordinate
                             Securities') in respect of certain distributions of
                             principal and interest and allocations of losses on
                             Mortgage Loans.

                           In addition, certain classes of Senior (or
                             Subordinate) Securities may be senior to other
                             classes of Senior (or Subordinate) Securities in 

                             respect of such distributions or losses.
    
                           Equity Securities will represent the right to receive
                             the proceeds of the related Trust Estate after all
                             required payments have been made to the
                             Securityholders of the related Fixed-Income
                             Securities (both Senior Securities and Subordinate
                             Securities), and following any required deposits to
                             any reserve account which may

                             be established for the benefit of the Fixed-Income
                             Securities. Equity Securities may constitute what
                             are commonly referred to as the 'residual
                             interest,' 'seller's interest' or the 'general
                             partnership interest,' depending upon the treatment
                             of the related Trust for federal income tax
                             purposes. As distinguished from the Fixed-Income
                             Securities, the Equity Securities will not be
                             styled as having principal and interest components.
                             Any losses suffered by the related Trust will first
                             be absorbed by the related class of Equity
                             Securities, as described herein and in the related
                             Prospectus Supplement.

                           No Class of Equity Securities will be offered
                             pursuant to this Prospectus or any Prospectus
                             Supplement related hereto. Equity Securities may be
                             offered on a private placement basis or pursuant to
                             a separate Registration Statement to be filed by
                             the Sponsor. In addition, the Sponsor and its
                             affiliates may initially or permanently hold any
                             Equity Securities issued by any Trust.

                           As provided in the related Pooling and Servicing
                             Agreement and as described in the related
                             Prospectus Supplement, Securityholders will be
                             entitled to receive payments on their Securities 
                             on specified dates (each, a 'Payment Date').
                             Payment Dates with respect to Fixed-Income
                             Securities will occur monthly, quarterly or
                             semi-annually, as described in the related
                             Prospectus Supplement; Payment Dates with respect
                             to Equity Securities will occur as described in the
                             related Prospectus Supplement.

                           The related Prospectus Supplement will describe a
                             date (the 'Record Date') preceding such Payment
                             Date, as of which the Trustee or its paying agent

                             will fix the identity of the Securityholders for
                             the purpose of receiving payments on the next
                             succeeding Payment Date. Unless otherwise described
                             in the related Prospectus Supplement, the Payment
                             Date will be the twenty-fifth day of each month
                             (or, in the case of quarterly-pay Securities, the
                             twenty-fifth day of every third month; and in the
                             case of semi-annual pay Securities, the
                             twenty-fifth day of every sixth month) and the
                             Record Date will be the close of business as of the
                             last day of the calendar month that precedes the
                             calendar month in which such Payment Date occurs.

                           Each Pooling and Servicing Agreement will describe
                             a period (each, a 'Remittance Period') antecedent
                             to each Payment Date (for example, in the case of
                             monthly-pay Securities, the calendar month
                             preceding the month in which a Payment Date occurs
                             or such other specified period). Unless otherwise
                             provided in the related Prospectus Supplement,
                             collections received on or with respect to the
                             related Mortgage Loans during a Remittance Period
                             will be required to be remitted by the Master
                             Servicer to the related Trustee prior to the
                             related Payment Date and will be used to fund
                             payments to Securityholders on such Payment Date.
                             As may be described in the related Prospectus
                             Supplement, the related Pooling and Servicing
                             Agreement may provide that all or a portion of the
                             principal collected on or with respect to the
                             related Mortgage Loans may be applied by the
                             related Trustee to the acquisition of additional
                             Mortgage Loans during a specified period (rather
                             than be used to fund payments of principal to

                             Securityholders during such period) with the result
                             that the related securities will possess an
                             interest-only period, also commonly referred to as
                             a revolving period, which will be followed by an
                             amortization period. Any such interest-only or
                             revolving period may, upon the occurrence of
                             certain events to be described in the related
                             Prospectus Supplement, terminate prior to the end
                             of the specified period and result in the earlier
                             than expected amortization of the related
                             Securities. 

                             In addition, and as may be described in
                             the related Prospectus Supplement, the related

                             Pooling and Servicing Agreement may provide that
                             all or a portion of such collected principal may be
                             retained by the Trustee (and held in certain
                             temporary investments, including Mortgage Loans)
                             for a specified period prior to being used to fund
                             payments of principal to Securityholders. 

                             The result of such retention and temporary
                             investment  by the Trustee of such principal would
                             be to slow the amortization rate of the related
                             Securities relative to the amortization rate of the
                             related Mortgage Loans, or to attempt to match the
                             amortization rate of the related Securities to an
                             amortization schedule established at the time such
                             Securities are issued. Any such feature applicable
                             to any Securities may terminate upon the occurrence
                             of events to be described in the related Prospectus
                             Supplement, resulting in the current distribution
                             of principal payments to the specified
                             Securityholders and an acceleration of the
                             amortization of such Securities. 

                           Unless otherwise specified in the related Prospectus
                             Supplement, neither the Securities nor the
                             underlying Mortgage Loans will be guaranteed or
                             insured by any governmental agency or
                             instrumentality or the Sponsor, the Master
                             Servicer, any Sub-Servicer, any Originator or any
                             of their affiliates.

No Investment Companies... Neither the Sponsor nor any Trust will register as an
                             'investment  company' under the Investment Company
                             Act of 1940, as amended (the 'Investment Company
                             Act').

Cross-Collateralization... Unless otherwise provided in the related Pooling and
                             Servicing Agreement and described in the related
                             Prospectus Supplement, the source of payment for
                             Securities of each series will be the assets of the
                             related Trust Estate only. However, as may be
                             described in the related Prospectus Supplement, a
                             Trust Estate may include the right to receive
                             moneys from a common pool of Credit Enhancement
                             which may be available for more than one series of
                             Securities, such as a master reserve account or a
                             master insurance policy. Notwithstanding the
                             foregoing, unless specifically described otherwise
                             in the related Prospectus Supplement, no
                             collections on any Mortgage Loans held by any Trust
                             may be applied to the payment of Securities issued
                             by any other Trust (except to the limited extent
                             that certain collections in excess of amounts
                             needed to pay the related Securities may be
                             deposited in a common, master reserve account that

                             provides Credit Enhancement for more than one
                             series of Securities)

The Mortgage Pools........ Unless otherwise specified in the related
                             Prospectus Supplement, each Trust Estate will
                             consist primarily of Mortgage Loans secured by
                             liens on one- to four-family residential or
                             multi-family properties ('Mortgages'), located in

Forward Commitments;
  Pre-Funding............. A Trust may enter into an agreement (each, a 'Forward
                             Purchase Agreement') with the Sponsor whereby the
                             Sponsor will agree to transfer additional Mortgage

                             Loans (the 'Subsequent Mortgage Loans') to such
                             Trust following the date on which such Trust is
                             established and the related Securities are issued.
                             Any Forward Purchase Agreement will require that
                             any Mortgage Loans so transferred to a Trust
                             conform to the requirements specified in such
                             Forward Purchase Agreement. In addition, the
                             Forward Purchase Agreement states that the
                             Depositor shall only transfer the Subsequent
                             Mortgage Loans upon the satisfaction of certain
                             conditions including that the Depositor shall have
                             delivered to the Certificate Insurer, the Rating
                             Agencies and the Trustee opinions of counsel
                             (including bankruptcy, corporate and tax opinions)
                             with respect to the transfer of the Subsequent
                             Mortgage Loans. If a Forward Purchase Agreement is
                             to be utilized, and unless otherwise specified in
                             the related Prospectus Supplement, the related
                             Trustee will be required to deposit in a segregated
                             account (each, a 'Pre-Funding Account') all or a
                             portion of the proceeds received by the Trustee in
                             connection with the sale of one or more classes of
                             Securities of the related series; subsequently, the
                             additional Mortgage Loans will be transferred to
                             the related Trust in exchange for money released to
                             the Sponsor from the related Pre-Funding Account in
                             one or more transfers. Each Forward Purchase
                             Agreement will set a specified period during which
                             any such transfers must occur. The Forward Purchase
                             Agreement or the related Pooling and Servicing
                             Agreement will require that, if

Advances.................. As to be described in the related Prospectus
                             Supplement, the Master Servicer may be obligated to
                             make certain advances with respect to payments of

                             the Mortgage Loans, but only to the extent that the
                             Master Servicer believes that such amounts will be
                             recoverable by it. Any such advance made by the
                             Master Servicer with respect to a Mortgage Loan is
                             recoverable by it as provided herein under
                             'Description of the Securities--Advances' either
                             from recoveries on the specific Mortgage Loan or,
                             with respect to any such advance subsequently
                             determined to be nonrecoverable, out of funds
                             otherwise distributable to the holders of the
                             related series of Securities, which may include the
                             holders of any Senior Securities of such series.

                           As to be described in the related Prospectus
                             Supplement, the Master Servicer may be required to

                             the Master Servicer reasonably believes that such
                             amounts will increase Net Liquidation Proceeds on
                             the related Mortgage Loan. See 'Description of the
                             Securities--Advances.'

                             Supplement.

Registration of 
  Securities.............. Securities may be represented by global securities
                             registered in the name of Cede & Co. ('Cede'), as
                             nominee of The Depository Trust Company ('DTC'), or
                             another nominee. In such case, Securityholders will
                             not be entitled to receive definitive securities
                             representing such Holders' interests, except in
                             certain circumstances described in the related
                             Prospectus Supplement. See 'Description of the
                             Securities--Form of Securities' herein.


Ratings................... Each class of Fixed-Income Securities offered
                             pursuant to the related Prospectus Supplement will
                             be rated in one of the four highest rating
                             categories by one or more 'national statistical
                             rating organizations,' as defined in the Securities
                             Exchange Act of 1934, as amended (the 'Exchange
                             Act'), and commonly referred to as 'Rating
                             Agencies.' Such ratings will address, in the
                             opinion of such Rating Agencies, the likelihood
                             that the related Trust will be able to make timely
                             payment of all amounts due on the related
                             Fixed-Income Securities in accordance with the
                             terms thereof. Such ratings will neither address
                             any prepayment or yield considerations applicable
                             to any Securities nor constitute a recommendation
                             to buy, sell or hold any Securities.

                           Equity Securities will not be rated.

                           The ratings expected to be received with respect
                             to any Securities will be set forth in the
                             related Prospectus Supplement.

                                 RISK FACTORS
 
     Investors should consider, among other things, the following factors in
connection with the purchase of the Securities.
 
     Limited Liquidity.  There can be no assurance that a secondary market for
the Securities of any series or class will develop or, if it does develop, that
it will provide Securityholders with liquidity of investment or that it will
continue for the life of the Securities of any series. The Prospectus Supplement
for any series of Securities may indicate that an underwriter specified therein
intends to establish a secondary market in such Securities; however, no
underwriter will be obligated to do so. Unless otherwise specified in the
related Prospectus Supplement, the Securities will not be listed on any
securities exchange.
 
     Limited Obligations.  The Securities will not represent an interest in or
obligation, either recourse or non-recourse (except for certain non-recourse
debt described under 'Certain Federal Income Tax Consequences'), of the Sponsor,
the Master Servicer, any Originator (as defined herein) or any person other than
the related Trust. The only obligations of the foregoing entities with respect
to the Securities or the Mortgage Loans will be the obligations (if any) of the
Sponsor, the related Originators and the Master Servicer pursuant to certain
limited representations and warranties made with respect to the Mortgage Loans,
the Master Servicer's servicing obligations under the related Pooling and
Servicing Agreement (including its limited obligation, if any, to make certain
advances in the event of delinquencies on the Mortgage Loans, but only to the
extent deemed recoverable) and, if and to the extent expressly described in the
related Prospectus Supplement, certain limited obligations of the Sponsor,

Master Servicer, applicable Sub-Servicer, or another party in connection with a
purchase obligation ('Purchase Obligation') or an agreement to purchase or act
as remarketing agent with respect to a Convertible Mortgage Loan upon conversion
to a fixed rate. Notwithstanding the foregoing, and as to be described in the
related Prospectus Supplement, certain types of Credit Enhancement, such as a
financial guaranty insurance policy or a letter of credit, may constitute a full
recourse obligation of the issuer of such Credit Enhancement. Except as
described in the related Prospectus Supplement, neither the Securities nor the
underlying Mortgage Loans will be guaranteed or insured by any governmental
agency or instrumentality, or by the Sponsor, the Master Servicer, any
Sub-Servicer or any of their affiliates. Proceeds of the assets included in the
related Trust Estate for each series of Securities (including the Mortgage Loans
and any form of Credit Enhancement) will be the sole source of payments on the
Securities, and there will be no recourse to the Sponsor or any other entity in
the event that such proceeds are insufficient or otherwise unavailable to make
all payments provided for under the Securities.
 
     Limitations, Reduction and Substitution of Credit Enhancement.  With
respect to each series of Securities, Credit Enhancement will be provided in
limited amounts to cover certain types of losses on the underlying Mortgage
Loans. Credit Enhancement will be provided in one or more of the forms referred
to herein, including, but not limited to: a letter of credit; a Purchase
Obligation; a mortgage pool insurance policy; a special hazard insurance policy;
a bankruptcy bond; a reserve fund; a financial guaranty insurance policy or
other type of Credit Enhancement to provide partial coverage for certain
defaults and losses relating to the Mortgage Loans. Credit Enhancement also may
be provided in the form of the related class of Equity Securities, subordination
of one or more classes of Fixed-Income Securities in a series under which losses
in excess of those absorbed by any related class of Equity Securities are first
allocated to any Subordinate Securities up to a specified limit, cross-support
among Mortgage Assets and/or overcollateralization. See 'Subordination' and
'Description of Credit Enhancement' herein. Regardless of the form of Credit
Enhancement provided, the coverage will be limited in amount and in most cases
will be subject to periodic reduction in accordance with a schedule or formula.
Furthermore, such Credit Enhancements may provide only very limited coverage as
to certain types of losses, and may provide no coverage as to certain other
types of losses. Generally, Credit Enhancements do not directly or indirectly
guarantee to the investors any specified rate of prepayments. The Master
Servicer will generally be permitted to reduce, terminate or substitute all or a
portion of the Credit Enhancement for any series of Securities, if the
applicable Rating Agency indicates that the then-current rating thereof will not
be adversely affected. To the extent not set forth herein, the amount and types
of coverage, the identification of any entity providing the coverage, the terms
of any subordination and related information will be set forth in the Prospectus
Supplement relating to a series of Securities. See 'Description of Credit
Enhancement' and 'Subordination.'
 
                                       13
<PAGE>

RISKS OF THE MORTGAGE LOANS
 
     Risk of the Losses Associated with Junior Liens.  Certain of the Mortgage
Loans will be secured by junior liens subordinate to the rights of the mortgagee

or beneficiary under each related senior mortgage or deed of trust. As a result,
the proceeds from any liquidation, insurance or condemnation proceedings will be
available to satisfy the principal balance of a mortgage loan only to the extent
that the claims, if any, of each such senior mortgagee or beneficiary are
satisfied in full, including any related foreclosure costs. In addition, a
mortgagee secured by a junior lien may not foreclose on the related mortgaged
property unless it forecloses subject to the related senior mortgage or
mortgages, in which case it must either pay the entire amount of each senior
mortgage to the applicable mortgagee at or prior to the foreclosure sale or
undertake the obligation to make payments on each senior mortgage in the event
of default thereunder. In servicing junior lien loans in its portfolio, it has
generally been the practice of the Master Servicer to satisfy each such senior
mortgage at or prior to the foreclosure sale but only to the extent that it
determines any amounts so paid will be recoverable from future payments and
collections on such junior lien loans or otherwise. The Trusts will not have any
source of funds to satisfy any such senior mortgage or make payments due to any
senior mortgagee. See 'Certain Legal Aspects of Mortgage Loans and Related
Matters--Foreclosure.'
 
     Risk of Losses Associated with Declining Real Estate Values.  An investment
in securities such as the Securities that generally represent beneficial
ownership interests in the Mortgage Loans or debt secured by such Mortgage Loans
may be affected by, among other things, a decline in real estate values and
changes in the borrowers' financial condition. No assurance can be given that
values of the Mortgaged Properties have remained or will remain at their levels
on the dates of origination of the related Mortgage Loans. If the residential
real estate market should experience an overall decline in property values such
that the outstanding balances of any senior liens, the Mortgage Loans and any
secondary financing on the Mortgaged Properties in a particular Mortgage Pool
become equal to or greater than the value of the Mortgaged Properties, the
actual rates of delinquencies, foreclosures and losses could be higher than
those now generally experienced in the nonconforming credit mortgage lending
industry. Such a decline could extinguish the interest of the related Trust in
the Mortgaged Properties before having any effect on the interest of the related
senior mortgagee. In addition, in the case of Mortgage Loans that are subject to
negative amortization, due to the addition to principal balance of deferred
interest ('Deferred Interest'), the principal balances of such Mortgage Loans
could be increased to an amount equal to or in excess of the value of the
underlying Mortgaged Properties, thereby increasing the likelihood of default.
To the extent that such losses are not covered by the applicable Credit
Enhancement, holders of Securities of the series evidencing interests in the
related Mortgage Pool will bear all risk of loss resulting from default by
Mortgagors and will have to look primarily to the value of the Mortgaged
Properties for recovery of the outstanding principal and unpaid interest on the
defaulted Mortgage Loans.
 
     Risk of Losses Associated with Certain Non-Conforming Credit and
Non-Traditional Loans.  The Sponsor's underwriting standards consider, among
other things, a mortgagor's credit history, repayment ability and debt
service-to-income ratio, as well as the value of the property; however, the
Sponsor's Mortgage Loan program generally provides for the origination of
Mortgage Loans relating to non-conforming credits. For purposes hereof,
'non-conforming credit' means a mortgage loan which, based upon standard
underwriting guidelines, is ineligible for purchase by the Federal National

Mortgage Association ('FNMA') or the Federal Home Loan Mortgage Corporation
('FHLMC') due to credit characteristics that do not meet FNMA or FHLMC
guidelines, respectively. Certain of the types of loans that may be included in
the Mortgage Pools may involve additional uncertainties not present in
traditional types of loans. For example, certain of the Mortgage Loans may
provide for escalating or variable payments by the borrower under the Mortgage
Loan (the 'Mortgagor'), as to which the Mortgagor is generally qualified on the
basis of the initial payment amount. In some instances the 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. For a
more detailed discussion, see 'Mortgage Loan Program.'
 
     Risk of Losses Associated with Balloon Loans.  Certain of the Mortgage
Loans may constitute 'Balloon Loans.' Balloon Loans are originated with a stated
maturity of less than the period of time of the corresponding amortization
schedule. Consequently, upon the maturity of a Balloon Loan, the Mortgagor will
be required to make a 'balloon' payment that will be significantly larger than
such Mortgagor's previous monthly payments. The ability of such a Mortgagor to
repay a Balloon Loan at maturity frequently will depend on such borrower's
 
                                       14
<PAGE>


ability to refinance the Mortgage Loan. The ability of a Mortgagor to refinance
such a Mortgage Loan will be affected by a number of factors, including the
level of available mortgage rates at the time, the value of the related
Mortgaged Property, the Mortgagor's equity in the related Mortgaged Property,
the financial condition of the Mortgagor, the tax laws and general economic
conditions at the time.
 
     Although a low interest rate environment may facilitate the refinancing of
a balloon payment, the receipt and reinvestment by Securityholders of the
proceeds in such an environment may produce a lower return than that previously
received in respect of the related Mortgage Loan. Conversely, a high interest
rate environment may make it more difficult for the Mortgagor to accomplish a
refinancing and may result in delinquencies or defaults. None of the Sponsor,
the Originators, the Master Servicer, any Sub-Servicer or the Trustee will be
obligated to provide funds to refinance any Mortgage Loan, including Balloon
Loans.
 
     Risk of Losses Associated with ARM Loans.  ARM 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.
 
     Risk of Losses Associated with Bankruptcy of Mortgagors.  General economic
conditions have an impact on the ability of borrowers to repay Mortgage Loans.
Loss of earnings, illness and other similar factors also may lead to an increase
in delinquencies and bankruptcy filings by borrowers. In the event of personal
bankruptcy of a Mortgagor, it is possible that a Trust could experience a loss
with respect to such Mortgagor's Mortgage Loan. In conjunction with a

Mortgagor's bankruptcy, a bankruptcy court may suspend or reduce the payments of
principal and interest to be paid with respect to such Mortgage Loan or
permanently reduce the principal balance of such Mortgage Loan thereby either
delaying or permanently limiting the amount received by the Trust with respect
to such Mortgage Loan. Moreover, in the event a bankruptcy court prevents the
transfer of the related Mortgaged Property to a Trust, any remaining balance on
such Mortgage Loan may not be recoverable.
 
     Risk of Losses Associated with Mortgaged Properties.  Even assuming that
the Mortgaged Properties provide adequate security for the Mortgage Loans,
substantial delays could be encountered in connection with the liquidation of
defaulted Mortgage Loans and corresponding delays in the receipt of related
proceeds by the Securityholders could occur. An action to foreclose on a
Mortgaged Property securing a Mortgage Loan is regulated by state statutes,
rules and judicial decisions and is subject to many of the delays and expenses
of other lawsuits if defenses or counterclaims are interposed, sometimes
requiring several years to complete. Furthermore, in some states an action to
obtain a deficiency judgment is not permitted following a nonjudicial sale of a
Mortgaged Property. In the event of a default by a Mortgagor, these
restrictions, among other things, may impede the ability of the Master Servicer
to foreclose on or sell the Mortgaged Property or to obtain liquidation proceeds
(net of expenses) ('Liquidation Proceeds') sufficient to repay all amounts due
on the related Mortgage Loan. The Master Servicer will be entitled to deduct
from Liquidation Proceeds all expenses reasonably incurred in attempting to
recover amounts due on the related liquidated Mortgage Loan ('Liquidated
Mortgage Loan') and not yet repaid, including payments to prior lienholders,
accrued Servicing Fees, Delinquency Advances, Servicing Advances, legal fees and
costs of legal action, real estate taxes, and maintenance and preservation
expenses. In the event that any Mortgaged Properties fail to provide adequate
security for the related Mortgage Loans and insufficient funds are available
from any applicable Credit Enhancement, Securityholders could experience a loss
on their investment.
 
     Liquidation expenses with respect to defaulted mortgage loans do not vary
directly with the outstanding principal balance of the loan at the time of
default. Therefore, assuming that a servicer takes the same steps in realizing
upon a defaulted mortgage loan having a small remaining principal balance as it
would in the case of a defaulted mortgage loan having a larger principal
balance, the amount realized after expenses of liquidation would be less as a
percentage of the outstanding principal balance of the smaller principal balance
mortgage loan than would be the case with a larger principal balance loan.
 
     Under environmental legislation and judicial decisions applicable in
various states, a secured party that takes a deed in lieu of foreclosure, or
acquires at a foreclosure sale a mortgaged property that, prior to foreclosure,
has been involved in decisions or actions which may lead to contamination of a
property, may be liable for the costs of cleaning up the purportedly
contaminated site. Although such costs could be substantial, it is unclear
whether they would be imposed on a holder of a mortgage note (such as a Trust)
which, under the terms of the Pooling
 
                                       15
<PAGE>


and Servicing Agreement, is not required to take an active role in operating the
Mortgaged Properties. See 'Certain Legal Aspects of Mortgage Loans and Related
Matters--Environmental Legislation.'
 
     Certain of the Mortgaged Properties relating to Mortgage Loans may not be
owner occupied. It is possible that the rate of delinquencies, foreclosures and
losses on Mortgage Loans secured by nonowner occupied properties could be higher
than for loans secured by the primary residence of the borrower.
 
     Litigation.  Any material litigation relating to the Sponsor or the Master
Servicer will be specified in the related Prospectus Supplement.
 
     Geographic Concentration of Mortgaged Properties.  Certain geographic
regions from time to time will experience weaker regional economic conditions
and housing markets than will other regions, and, consequently, will experience
higher rates of loss and delinquency on mortgage loans generally. The Mortgage
Loans underlying certain series of Securities may be concentrated in such
regions, and such concentrations may present risk considerations in addition to
those generally present for similar mortgage loan asset-backed securities
without such concentrations. Information with respect to geographic
concentration of Mortgaged Properties will be specified in the related
Prospectus Supplement or related Current Report on Form 8-K.
 
     Legal Considerations.  Applicable state laws generally regulate interest
rates and other charges, require certain disclosures, and require licensing of
the Originators and the Master Servicer and Sub-Servicers. In addition, most
states have other laws, public policy and general principles of equity relating
to the protection of consumers, unfair and deceptive practices and practices
that may apply to the origination, servicing and collection of the Mortgage
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 Master Servicer to collect all or part of the
principal of or interest on the Mortgage Loans, may entitle the borrower to a
refund of amounts previously paid and, in addition, could subject the Master
Servicer to damages and administrative sanctions. See 'Certain Legal Aspects of
Mortgage Loans and Related Matters.'
 
     The Mortgage Loans may also be subject to federal laws, including: (i) the
Federal Truth-in-Lending Act and Regulation Z promulgated thereunder and the
Real Estate Settlement Procedures Act and Regulation X promulgated thereunder,
which require certain disclosures to the borrowers regarding the terms of the
Mortgage 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; and (iii) the Fair Credit Reporting Act, which
regulates the use and reporting of information related to the borrower's credit
experience. Depending on the provisions of the applicable law and the specific
facts and circumstances involved, violations of these laws, policies and general
principles of equity may limit the ability of the Master Servicer to collect all
or part of the principal of or interest on the Mortgage Loans, may entitle the
borrower to rescind the loan or to a refund of amounts previously paid and, in
addition, could subject the Master Servicer to damages and administrative
sanctions. If the Master Servicer is unable to collect all or part of the

principal or interest on the Mortgage Loans because of a violation of the
aforementioned laws, public policies or general principles of equity then the
Trust may be delayed or unable to repay all amounts owed to Investors.
Furthermore, depending upon whether damages and sanctions are assessed against
the Master Servicer or an Originator, such violations may materially impact the
financial ability of the Sponsor to continue to act as Master Servicer or the
ability of an Originator to repurchase or replace Mortgage Loans if such
violation breaches a representation or warranty contained in a Pooling and
Servicing Agreement.
 
     Yield and Prepayment Considerations.  The yield to maturity of the
Securities of each series will depend on the rate of payment of principal
(including prepayments, liquidations due to defaults, and repurchases due to
conversion of adjustable-rate mortgage loans ('ARM Loans') to fixed-rate loans
or breaches of representations and warranties) on the Mortgage Loans and the
price paid by Securityholders. Such yield may be adversely affected by a higher
or lower than anticipated rate of prepayments on the related Mortgage Loans. The
yield to maturity on Strip Securities or Securities purchased at premiums or
discounted to par will be extremely sensitive to the rate of prepayments on the
related Mortgage Loans. In addition, the yield to maturity on certain other
types of classes of Securities, including Accrual Securities or certain other
classes in a series including more than one class of Securities, may be
relatively more sensitive to the rate of prepayment on the related Mortgage
Loans than other classes of Securities.
 
                                       16
<PAGE>

     Unless otherwise specified in the related Prospectus Supplement, the
Mortgage Loans may be prepaid in full or in part at any time; however, a
prepayment penalty or premium may be imposed in connection therewith. Unless so
specified in the related Prospectus Supplement, such penalties will not be
property of the related Trust. The rate of prepayments of the Mortgage Loans
cannot be predicted and is influenced by a wide variety of economic, social, and
other factors, including prevailing mortgage market interest rates, the
availability of alternative financing, local and regional economic conditions
and homeowner mobility. Therefore, no assurance can be given as to the level of
prepayments that a Trust will experience.
 
     Prepayments may result from mandatory prepayments relating to unused moneys
held in Pre-Funding Accounts, if any, voluntary early payments by borrowers
(including payments in connection with refinancings of the related senior
Mortgage Loan or Loans), sales of Mortgaged Properties subject to 'due-on-sale'
provisions and liquidations due to default, as well as the receipt of proceeds
from physical damage, credit life and disability insurance policies. In
addition, repurchases or purchases from a Trust of Mortgage Loans or
substitution adjustments required to be made under the Pooling and Servicing
Agreement will have the same effect on the Securityholders as a prepayment of
such Mortgage Loans. Unless otherwise specified in the related Prospectus
Supplement, all of the Mortgage Loans contain 'due-on-sale' provisions, and the
Master Servicer will be required to enforce such provisions unless (i) the
'due-on-sale' clause, in the reasonable belief of the Master Servicer, is not
enforceable under applicable law or (ii) the Master Servicer reasonably believes
that to permit an assumption of the Mortgage Loan would not materially and

adversely affect the interests of the Securityholders or of the related Credit
Enhancer, if any. See 'The Pooling and Servicing Agreement' in the related
Prospectus Supplement.
 
     Collections on the Mortgage Loans may vary due to the level of incidence of
delinquent payments and of prepayments. Collections on the Mortgage Loans may
also vary due to seasonal purchasing and payment habits of borrowers.
 
     Book-Entry Registration.  Issuance of the Securities in book-entry form 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
definitive physical securities representing such Securityholders' interests,
except in certain circumstances described in the related Prospectus Supplement.
 
     Since transactions in Securities will, in most cases, be able to be
effected only through DTC, direct or indirect participants in DTC's book-entry
system ('Direct or Indirect Participants') and certain banks, the ability of a
Securityholder to pledge a Security to persons or entities that do not
participate in the DTC system, or otherwise to take actions in respect of such
Securities, may be limited due to lack of a physical security representing the
Securities.
 
     Securityholders may experience some delay in their receipt of distributions
of interest on and principal of the Securities since distributions may be
required to be forwarded by the Trustee to DTC and, in such a case, DTC will be
required to credit such distributions to the accounts of its Participants which
thereafter will be required to credit them to the accounts of the applicable
class of Securityholders either directly or indirectly through Indirect
Participants. See 'Description of the Securities--Form of Securities.'
 
     The Status of the Mortgage Loans in the Event of Bankruptcy of the Sponsor
or an Originator.  In the event of the bankruptcy of the Sponsor or an
Originator at a time when it or any affiliate thereof holds an Equity Security,
a trustee in bankruptcy of the Sponsor, an Originator, or its creditors could
attempt to recharacterize the sale of the Mortgage Loans to the related Trust as
a borrowing by the Sponsor, the Originator or such affiliate with the result, if
such recharacterization is upheld, that the Securityholders would be deemed
creditors of the Sponsor, the Originator or such affiliate, secured by a pledge
of the Mortgage Loans. If such an attempt were successful, it could prevent
timely payments of amounts due to the Trust.
 
     Limitations on Interest Payments and Foreclosures.  Generally, under the
terms of the Soldiers' and Sailors' Civil Relief Act of 1940, as amended (the
'Relief Act'), or similar state legislation, a Mortgagor who enters military
service after the origination of the related Mortgage Loan (including a
Mortgagor who is a member of the National Guard or is in reserve status at the
time of the origination of the Mortgage Loan and is later called to active duty)
may not be charged interest (including fees and charges) above an annual rate of
6% during the period of such Mortgagor's active duty status, unless a court
orders otherwise upon application of the
 
                                       17
<PAGE>


lender. It is possible that such action could have an effect, for an
indeterminate period of time, on the ability of the Master Servicer to collect
full amounts of interest on certain of the Mortgage Loans. In addition, the
Relief Act imposes limitations that would impair the ability of the Master
Servicer to foreclose on an affected Mortgage Loan during the Mortgagor's period
of active duty status. Thus, in the event that such a Mortgage Loan goes into
default, there may be delays and losses occasioned by the inability to realize
upon the Mortgaged Property in a timely fashion.
 
     Security Rating.  The rating of Securities credit enhanced through external
Credit Enhancement such as a letter of credit, financial guaranty insurance
policy or mortgage pool insurance will depend primarily on the creditworthiness
of the issuer of such external Credit Enhancement device (a 'Credit Enhancer').
Any reduction in the rating assigned to the claims-paying ability of the related
Credit Enhancer below the rating initially given to the Securities would likely
result in a reduction in the rating of the Securities. See 'Ratings' in the
Prospectus Supplement.
 
                                  THE TRUSTS
 
     A Trust for any series of Securities will include the primary mortgage
assets ('Mortgage Assets') consisting of (A) a Mortgage Pool comprised of (i)
Single Family Loans, (ii) Multi-family Loans, (iii) Cooperative Loans, (iv)
Contracts, (v) Home Improvement Loans, or (vi) other loans or (B) certificates
of interest or participation in the items described in clause (A) or in pools of
such items, in each case, as specified in the related Prospectus Supplement,
together with payments in respect of such primary Mortgage Assets and certain
other accounts, obligations or agreements, in each case as specified in the
related Prospectus Supplement.
 
     Unless otherwise specified in the related Prospectus Supplement, the
Securities will be entitled to payment only from the assets of the related Trust
(i.e., the related Trust Estate) and will not be entitled to payments in respect
of the assets of any other related Trust Estate established by the Sponsor, the
Originators or any of their affiliates. If specified in the related Prospectus
Supplement, certain Securities will evidence the entire fractional undivided
ownership interest in the related Mortgage Loans held by the related Trust or
may represent debt secured by the related Mortgage Loans.
 
     The following is a brief description of the Mortgage Assets expected to be
included in the related Trusts. If specific information respecting the primary
Mortgage Assets is not known at the time the related series of Securities
initially is offered, information of the nature described below will be provided
in the Prospectus Supplement, and specific information will be set forth in a
report on Form 8-K to be filed with the Commission within fifteen days after the
initial issuance of such Securities (the 'Detailed Description'). A copy of the
Pooling and Servicing Agreement with respect to each Series of Securities will
be attached to the Form 8-K and will be available for inspection at the
corporate trust office of the Trustee specified in the related Prospectus
Supplement. A schedule of the Mortgage Assets relating to such Series (the
'Mortgage Asset Schedule') will be attached to the Pooling and Servicing
Agreement delivered to the Trustee upon delivery of the Securities.
 
     The Mortgage Loans--General.  The real properties and Manufactured Homes,

as the case may be, that secure repayment of the Mortgage Loans and Contracts
(the 'Mortgaged Properties') may be located in any one of the fifty states, the
District of Columbia, Puerto Rico or any other Territories of the United States.
Unless otherwise specified in the related Prospectus Supplement, the Mortgage
Loans or Contracts will be 'Conventional Loans' (i.e., loans that are not
insured or guaranteed by any governmental agency). If specified in the related
Prospectus Supplement, Mortgage Loans with certain loan-to-value ratios and/or
certain principal balances may be covered wholly or partially by primary
mortgage insurance policies. Unless otherwise specified in the related
Prospectus Supplement, all of the Mortgage Loans will be covered by standard
hazard insurance policies (which may be in the form of a blanket or forced
placed hazard insurance policy). The existence, extent and duration of any such
coverage will be described in the applicable Prospectus Supplement. Unless
otherwise described in the related Prospectus Supplement, the Mortgage Loans
will not be guaranteed or insured by any government agency or other insurer.
 
     Unless otherwise specified in the related Prospectus Supplement, all of the
Mortgage Loans in a Mortgage Pool will provide for payments to be made monthly
('monthly pay') or bi-weekly. The payment terms of the Mortgage Loans to be
included in a Trust will be described in the related Prospectus Supplement and
may
 
                                       18
<PAGE>

include any of the following features or combination thereof or other features
described in the related Prospectus Supplement:
 
          (a) Interest may be payable at a Fixed Rate, or an Adjustable Rate
     (i.e., a rate that is adjustable from time to time in relation to an index,
     a rate that is fixed for a period of time and under certain circumstances
     is followed by an adjustable rate, a rate that otherwise varies from time
     to time, or a rate that is convertible from an adjustable rate to a fixed
     rate). The specified rate of interest on a Mortgage Loan is its 'Mortgage
     Rate.' Changes to an Adjustable Rate may be subject to periodic
     limitations, maximum rates, minimum rates or a combination of such
     limitations. Accrued interest may be deferred and added to the principal of
     a Mortgage Loan for such periods and under such circumstances as may be
     specified in the related Prospectus Supplement. If provided for in the
     Prospectus Supplement, certain Mortgage Loans may be subject to temporary
     buydown plans ('Buydown Mortgage Loans') pursuant to which the monthly
     payments made by the Mortgagor during the early years of the Mortgage Loan
     (the 'Buydown Period') will be less than the scheduled monthly payments on
     the Mortgage Loan, and the amount of any difference may be contributed from
     (i) an amount (such amount, exclusive of investment earnings thereon, being
     hereinafter referred to as 'Buydown Funds') funded by the originator of the
     Mortgage Loan or another source (including the Master Servicer or the
     related Originator and the builder of the Mortgaged Property) and placed in
     a custodial account (the 'Buydown Account') and (ii) if the Buydown Funds
     are contributed on a present value basis, investment earnings on such
     Buydown Funds.
 
          (b) Principal may be payable on a level debt service basis to fully
     amortize the Mortgage Loan over its term, may be calculated on the basis of

     an assumed amortization schedule that is significantly longer than the
     original term to maturity or on an interest rate that is different from the
     Mortgage Rate, or may not be amortized during all or a portion of the
     original term. Payment of all or a substantial portion of the principal may
     be due on maturity ('balloon payments'). Principal may include interest
     that has been deferred and added to the principal balance of the Mortgage
     Loan.
 
          (c) Monthly payments of principal and interest may be fixed for the
     life of the Mortgage Loan, may increase over a specified period of time
     ('graduated payments') or may change from period to period. Mortgage Loans
     may include limits on periodic increases or decreases in the amount of
     monthly payments and may include maximum or minimum amounts of monthly
     payments. Mortgage Loans having graduated payment provisions may provide
     for deferred payment of a portion of the interest due monthly during a
     specified period, and recoup the deferred interest through negative
     amortization during such period whereby the difference between the interest
     paid during such period and interest accrued during such period is added
     monthly to the outstanding principal balance. Other Mortgage Loans
     sometimes referred to as 'growing equity' mortgage loans may provide for
     periodic scheduled payment increases for a specified period with the full
     amount of such increases being applied to principal.
 
          (d) Prepayments of principal may be subject to a prepayment fee, which
     may be fixed for the life of the Mortgage Loan or may decline over time,
     and may be prohibited for the life of the Mortgage Loan or for certain
     periods ('lockout periods'). Certain Mortgage Loans may permit prepayments
     after expiration of the applicable lockout period and may require the
     payment of a prepayment fee in connection therewith. Other Mortgage Loans
     may permit prepayments without payment of a fee unless the prepayment
     occurs during specified time periods. The Mortgage Loans may include
     due-on-sale clauses which permit the mortgagee to demand payment of the
     entire Mortgage Loan in connection with the sale or certain transfers of
     the related Mortgaged Property. Other Mortgage Loans may be assumable by
     persons meeting the then applicable underwriting standards of the related
     Originator.
 
          (e) As more fully described in the related Prospectus Supplement, the
     Mortgage Loans may consist, in whole or in part, of revolving home equity
     loans or certain balances thereof ('Revolving Credit Line Loans'). Interest
     on each Revolving Credit Line Loan, excluding introductory rates offered
     from time to time during promotional periods, may be computed and payable
     monthly on the average daily outstanding principal balance of such loan.
     From time to time prior to the expiration of the related draw period
     specified in a Revolving Credit Line Loan, principal amounts on such
     Revolving Credit Line Loan may be drawn down (up to a maximum amount as set
     forth in the related Prospectus Supplement) or repaid. If specified in the
     related Prospectus Supplement, new draws by borrowers under the Revolving
     Credit Line Loans will
 
                                       19
<PAGE>

     automatically become part of the Trust Estate described in such Prospectus

     Supplement. As a result, the aggregate balance of the Revolving Credit Line
     Loans will fluctuate from day to day as new draws by borrowers are added to
     the Trust Estate and principal payments are applied to such balances and
     such amounts will usually differ each day, as more specifically described
     in the related Prospectus Supplement. Under certain circumstances, under a
     Revolving Credit Line Loan, a borrower may, during the related draw period,
     choose an interest only payment option, during which the borrower is
     obligated to pay only the amount of interest which accrues on the loan
     during the billing cycle, and may also elect to pay all or a portion of the
     principal. An interest only payment option may terminate at the end of the
     related draw period, after which the borrower must begin paying at least a
     minimum monthly portion of the average outstanding principal balance of the
     loan.
 
     Except as otherwise described in the related Prospectus Supplement or in
the related Current Report on Form 8-K, interest will be calculated on each
Mortgage Loan pursuant to one of three methods:
 
          Date of Payment Loans.  Date of Payment Loans provide that interest is
     charged to the Mortgagor at the applicable Mortgage Rate on the outstanding
     principal balance of such Note and calculated based on the number of days
     elapsed between receipt of the Mortgagor's last payment through receipt of
     the Mortgagor's most current payment. Such interest is deducted from the
     Mortgagor's payment amount and the remainder, if any, of the payment is
     applied as a reduction to the outstanding principal balance of such Note.
     Although the Mortgagor is required to remit equal monthly payments on a
     specified monthly payment date that would reduce the outstanding principal
     balance of such Note to zero at such Note's maturity date, payments that
     are made by the Mortgagor after the due date therefor would cause the
     outstanding principal balance of such Note not to be reduced to zero. In
     such a case, the Mortgagor would be required to make an additional
     principal payment at the maturity date for such Note. On the other hand, if
     a Mortgagor makes a payment (other than a prepayment) before the due date
     therefor, the reduction in the outstanding principal balance of such Note
     would occur over a shorter period of time than it would have occurred had
     it been based on the original amortization schedule of such Note.
 
          Actuarial Loans.  Actuarial Loans provide that interest is charged to
     the Mortgagor thereunder, and payments are due from such Mortgagor, as of a
     scheduled day of each month which is fixed at the time of origination.
     Scheduled monthly payments made by the Mortgagors on the Actuarial Loans
     either earlier or later than the scheduled due dates thereof will not
     affect the amortization schedule or the relative application of such
     payments to principal and interest.
 
          Rule of 78's Loans.  A Rule of 78's Loan provides for the payment by
     the related Mortgagor of a specified total amount of payments, payable in
     equal monthly installments on each due date, which total represents the
     principal amount financed and add-on interest in an amount calculated on
     the basis of the stated Mortgage Rate for the term of the Loan. The rate at
     which such amount of add-on interest is earned and, correspondingly, the
     amount of each fixed monthly payment allocated to reduction of the
     outstanding principal are calculated in accordance with the 'Rule of 78's.'
     Under a Rule of 78's Loan, the amount of a payment allocable to interest is

     determined by multiplying the total amount of add-on interest payable over
     the term of the loan by a fraction derived as described below.
 
     The fraction used in the calculation of add-on interest earned each month
under a Rule of 78's Loan has as its denominator a number equal to the sum of a
series of numbers. The series of numbers begins with one and ends with the
number of monthly payments due under the loan. For example, with a loan
providing for 12 payments, the denominator of each month's fraction will be 78,
the sum of the series of numbers from 1 to 12. The numerator of the fraction for
a given month is the number of original payments to stated maturity less the
number of payments made up to but not including the current month. Accordingly,
in the example of a twelve-month loan, the fraction for the first payment is,
for the second payment, for the third party, and so on through the final
payment, for which the fraction is. The applicable fraction is then multiplied
by the total add-on interest payable over the entire term of the loan, and the
resulting amount is the amount of add-on interest 'earned' that month. The
difference between the amount of the monthly payment by the obligor and the
amount of earned add-on interest calculated for the month is applied to
principal reduction. Rule of 78's Loans are non-level yield instruments. The
yield in the initial months of a Rule of 78's Loans is somewhat higher than the
stated Mortgage
 
                                       20
<PAGE>

Rate (computed on an actuarial basis) and the yield in the later months of the
loan is somewhat less than such stated Mortgage Rate.
 
     The Prospectus Supplement for each series of Securities or the Current
Report on Form 8-K will contain certain information with respect to the Mortgage
Loans (or a sample thereof) contained in the related Mortgage Pool; such
information, insofar as it may relate to statistical information relating to
such Mortgage Loans will be presented as of a date certain (the 'Statistic
Calculation Date') which may also be the related cut-off date (the 'Cut-Off
Date'). Such information will include to the extent applicable to the particular
Mortgage Pool (in all cases as of the Statistic Calculation Date) (i) the
aggregate outstanding principal balance and the average outstanding principal
balance of the Mortgage Loans, (ii) the largest principal balance and the
smallest principal balance of any of the Mortgage Loans, (iii) the types of
Mortgaged Property securing the Mortgage Loans (e.g., one- to four-family
houses, vacation and second homes, Manufactured Homes, multifamily apartments or
other real property), (iv) the original terms to stated maturity of the Mortgage
Loans, (v) the weighted average remaining term to maturity of the Mortgage Loans
and the range of the remaining terms to maturity; (vi) the earliest origination
date and latest maturity date of any of the Mortgage Loans, (vii) the weighted
average CLTV and the range of CLTV's of the Mortgage Loans at origination,
(viii) the weighted average Mortgage Rate or annual percentage rate (as
determined under Regulation Z) (the 'APR') and ranges of Mortgage Rates or APRs
borne by the Mortgage Loans, (ix) in the case of Mortgage Loans having
adjustable rates, the weighted average of the adjustable rates and indices, if
any; (x) the aggregate outstanding principal balance, if any, of Buy-Down Loans
and Mortgage Loans having graduated payment provisions; (xi) the amount of any
mortgage pool insurance policy, special hazard insurance policy or bankruptcy
bond to be maintained with respect to such Mortgage Pool; (xii) a description of

any standard hazard insurance required to be maintained with respect to each
Mortgage Loan; (xiii) a description of any Credit Enhancement to be provided
with respect to all or any Mortgage Loans or the Mortgage Pool; and (xiv) the
geographical distribution of the Mortgage Loans on a state-by-state basis. In
addition, preliminary or more general information of the nature described above
may be provided in the Prospectus Supplement, and specific or final information
may be set forth in a Current Report on Form 8-K, together with the related
Pooling and Servicing Agreement, which will be filed with the Securities and
Exchange Commission and will be made available to holders of the related series
of Securities within fifteen days after the initial issuance of such Securities.
 
     The loan-to-value ratio (the 'LTV') of a Mortgage Loan is equal to the
ratio (expressed as a percentage) of the original principal balance of such
Mortgage Loan to appraised value of the related Mortgaged Property (unless
otherwise disclosed in the related Prospectus Supplement or in the related
Current Report on Form 8-K, less the amount, if any, of the premium for any
credit life insurance) at the time of origination of the Mortgage Loan or, in
the case where the Mortgage represents a purchase money instrument, the lesser
of (a) the appraised value or (b) the purchase price. The combined loan-to-value
ratio (the 'CLTV') of a Mortgage Loan at any given time is the ratio, expressed
as a percentage, determined by dividing (x) the sum of the original principal
balance of such Mortgage Loan (unless otherwise disclosed in the related
Prospectus Supplement or in the related Current Report on Form 8-K, less the
amount, if any, of the premium for any credit life insurance) plus the then-
current principal balance of all mortgage loans (each, a 'Senior Lien') secured
by liens on the related Mortgaged Property having priorities senior to that of
the lien which secures such Mortgage Loan, by (y) the value of the related
Mortgaged Property, based upon the appraisal or valuation (which may in certain
instances include estimated increases in value as a result of certain home
improvements to be financed with the proceeds of such Mortgage Loan) made at the
time of origination of the Mortgage Loan. If the related Mortgagor will use the
proceeds of the Mortgage Loan to refinance an existing Mortgage Loan which is
being serviced directly or indirectly by the Master Servicer, the requirement of
an appraisal or other valuation at the time the new Mortgage Loan is made may be
waived. Unless otherwise specified in the related Prospectus Supplement, for
purposes of calculating the CLTV of a Contract relating to a new Manufactured
Home, the value of such Manufactured Home will be no greater than the sum of a
fixed percentage of the list price of the unit actually billed by the
manufacturer to the dealer (exclusive of freight to the dealer site) including
'accessories' identified in the invoice (the 'Manufacturer's Invoice Price'),
plus the actual cost of any accessories purchased from the dealer, a delivery
and set-up allowance, depending on the size of the unit, and the cost of state
and local taxes, filing fees and up to three years prepaid hazard insurance
premiums. Unless otherwise specified herein or in the related Prospectus
Supplement, the value of a used Manufactured Home will be either (x) the
appraised value, and National Automobile Dealer's Association book value plus
prepaid taxes and hazard insurance premiums or
 
                                       21
<PAGE>

(y) the sum of (i) the appraised value of the land to which the Manufactured
Home is attached and (ii) the appraised value of the Manufactured Home. The
appraised value of a Manufactured Home will be based upon the age and condition

of the manufactured housing unit and the quality and condition of the mobile
home park in which it is situated, if applicable.
 
     No assurance can be given that values of the Mortgaged Properties have
remained or will remain at their levels on the dates of origination of the
related Mortgage Loans. If the residential real estate market should experience
an overall decline in property values such that the outstanding principal
balances of the Mortgage Loans (plus any additional financing by other lenders
on the same Mortgaged Properties) in a particular Pool become equal to or
greater than the value of such Mortgaged Properties, the actual rates of
delinquencies, foreclosures and losses could be higher than those now generally
experienced in the non-conforming credit mortgage lending industry. An overall
decline in the market value of residential real estate, the general condition of
a Mortgaged Property, or other factors, could adversely affect the values of the
Mortgaged Properties such that the outstanding balances of the Mortgage Loans,
together with any additional liens on the Mortgaged Properties, equal or exceed
the value of the Mortgaged Properties. Under such circumstances, the actual
rates of delinquencies, foreclosures and losses could be higher than those now
generally experienced in the non-conforming credit mortgage lending industry.
 
     Certain Mortgage Loans may be secured by junior liens ('Junior Lien Loans')
subordinate to the rights of the mortgagee under any related senior mortgage(s).
The proceeds from any liquidation, insurance or condemnation of Mortgaged
Properties relating to Junior Lien Loans in a Mortgage Pool will be available to
satisfy the principal balance of such Junior Lien Loans only to the extent that
the claims, if any, of all related senior mortgagees, including any related
foreclosure costs, are satisfied in full. In addition, the Master Servicer may
not foreclose on a Mortgaged Property relating to a Junior Lien Loan unless it
forecloses subject to the related senior mortgage or mortgages, in which case it
must either pay the entire amount of each senior mortgage to the applicable
mortgagee at or prior to the foreclosure sale or undertake the obligation to
make payments on each senior mortgage in the event of default thereunder.
Generally, in servicing Junior Lien Loans in its loan portfolios, it has been
the Master Servicer's practice to satisfy each senior mortgage at or prior to a
foreclosure sale but only to the extent that it determines any amounts so paid
will be recoverable from future payments and collections on the Mortgage Loans
or otherwise. The Trusts will not have any source of funds to satisfy any such
senior mortgage or make payments due to any senior mortgagee. See 'Certain Legal
Aspects of Mortgage Loans and Related Matters--Foreclosure.'
 
     Other factors affecting mortgagors' ability to repay Mortgage Loans include
excessive building resulting in an oversupply of housing stock or a decrease in
employment reducing the demand for units in an area; federal, state or local
regulations and controls affecting rents; prices of goods and energy;
environmental restrictions; increasing labor and material costs; and the
relative attractiveness of the Mortgaged Properties. To the extent that losses
on the Mortgage Loans are not covered by Credit Enhancements, such losses will
be borne, at least in part, by the Securityholders of the related series.
 
     The Sponsor will cause the Mortgage Loans comprising each Mortgage Pool to
be assigned to the Trustee named in the related Prospectus Supplement for the
benefit of the holders of the Securities of the related series. The Master
Servicer will service the Mortgage Loans, either directly or through
Sub-Servicers, pursuant to the Pooling and Servicing Agreement and will receive

a fee for such services. See 'Mortgage Loan Program' and 'The Pooling and
Servicing Agreement.' With respect to Mortgage Loans serviced through a
Sub-Servicer, the Master Servicer will remain liable for its servicing
obligations under the related Pooling and Servicing Agreement as if the Master
Servicer alone were servicing such Mortgage Loans.
 
     Unless otherwise specified in the related Prospectus Supplement, the only
obligations of the Sponsor and the Originators with respect to a series of
Securities will be to provide (or, where the Sponsor or an Originator acquired a
Mortgage Loan from another originator, obtain from such originator) certain
representations and warranties concerning the Mortgage Loans and to assign to
the Trustee for such series of Securities the Sponsor's or Originator's rights
with respect to such representations and warranties. See 'The Pooling and
Servicing Agreement.' The obligations of the Master Servicer with respect to the
Mortgage Loans will consist principally of its contractual servicing obligations
under the related Pooling and Servicing Agreement (including its obligation to
enforce the obligations of the Sub-Servicers or Originators as more fully
described herein under 'Mortgage Loan Program--Qualifications of Originators'
and 'The Pooling and Servicing Agreement') and
 
                                       22
<PAGE>
its obligation, as described in the related Prospectus Supplement, to make
certain cash advances in the event of delinquencies in payments on, or
prepayments received with respect to, the Mortgage Loans in the amounts
described herein under 'Description of the Securities--Advances.' The
obligations of a Master Servicer to make advances may be subject to limitations,
to the extent provided herein and in the related Prospectus Supplement.
 
     Single Family and Cooperative Loans.  Unless otherwise specified in the
Prospectus Supplement, single family loans will consist of mortgage loans, deeds
of trust or participation or other beneficial interests therein, secured by
first or junior liens on one- to four-family residential properties ('Single
Family Loans'). The Mortgaged Properties relating to Single Family Loans will
consist of detached or semi-detached one-family dwelling units, two- to
four-family dwelling units, townhouses, rowhouses, individual condominium units
in condominium developments, individual units in planned unit developments, and
certain mixed use and other dwelling units. Such Mortgaged Properties may
include owner-occupied (which includes vacation and second homes) and non-owner
occupied investment properties.
 
     If so specified, the Single Family Loans may include loans or
participations therein secured by mortgages or deeds of trust on condominium
units in low- or high-rise condominium developments together with such
condominium units' appurtenant interests in the common elements of such
condominium developments. Unless otherwise specified, the Cooperative Loans will
be secured by security interests in or similar liens on stock, shares or
membership certificates issued by cooperatives and in the related proprietary
leases or occupancy agreements granting exclusive rights to occupy specific
dwelling units in such cooperatives' buildings.
 
     Multi-family Loans.  Multi-family loans will consist of mortgage loans,
deeds of trust or participation or other beneficial interests therein, secured
by first or junior liens on rental apartment buildings or projects containing

five or more residential units ('Multi-family Loans').
 
     Mortgaged Properties that secure Multi-family Loans may include high-rise,
mid-rise and garden apartments.   Certain of the Multi-family Loans may be
secured by apartment buildings owned by Cooperatives. In such cases, the
Cooperative owns all the apartment units in the building and all common areas.
The Cooperative is owned by tenant-stockholders who, through ownership of stock,
shares or membership certificates in the corporation, receive proprietary leases
or occupancy agreements that confer exclusive rights to occupy specific
apartments or units. Generally, a tenant-stockholder of a Cooperative must make
a monthly payment to the Cooperative representing such tenant-stockholder's pro
rata share of the Cooperative's payments for its mortgage loan, real property
taxes, maintenance expenses and other capital or ordinary expenses. Those
payments are in addition to any payments of principal and interest the
tenant-stockholder must make on any loans to the tenant-stockholder secured by
its shares in the Cooperative. The Cooperative will be directly responsible for
building management and, in most cases, payment of real estate taxes and hazard
and liability insurance. A Cooperative's ability to meet debt service
obligations on a Multi-family Loan, as well as all other operating expenses,
will be dependent in large part on the receipt of maintenance payments from the
tenant-stockholders, as well as any rental income from units or commercial areas
the Cooperative might control. Unanticipated expenditures may in some cases have
to be paid by special assessments on the tenant-stockholders.
 
     Home Improvement Loans.  Unless otherwise specified in the Prospectus
Supplement, loans to make home improvements may be secured by first or junior
liens on conventional one- to four-family residential properties and
multi-family residential properties ('Home Improvement Loans'). Home Improvement
Loans may be conventional, or may be partially insured by the Federal Housing
Administration ('FHA') or another federal or state agency, as specified in the
related Prospectus Supplement. The loan proceeds from such Home Improvement
Loans are typically disbursed to an escrow agent which, according to guidelines
established by the Originators, releases such proceeds to the contractor upon
completion of the improvements or in draws as the work on the improvements
progresses. Costs incurred by the Mortgagor for loan origination including
origination points and appraisal, legal and title fees, are often included in
the amount financed. In addition, Home Improvement Loans generally provide
additional security to a first or junior mortgage loan because home improvements
typically retain or increase the value of a property.
 
     Contracts.  Contracts will consist of manufactured housing conditional
sales contracts and installment sales or loan agreements each secured by a
Manufactured Home ('Contracts'). Contracts may be conventional, insured
partially by the FHA or partially guaranteed by the Veterans Administration, as
specified in the related
 
                                       23
<PAGE>
Prospectus Supplement. Unless otherwise specified in the related Prospectus
Supplement, each Contract will be fully amortizing and will bear interest at its
APR.
 
     Unless otherwise specified in the related Prospectus Supplement, the
'Manufactured Homes' securing the Contracts will consist of manufactured homes

within the meaning of 42 United States Code, Section 5402(6), which defines a
'manufactured home' as 'a structure, transportable in one or more sections,
which in the traveling mode, is eight body feet or more in width or forty body
feet or more in length, or, when erected on site, is three hundred twenty or
more square feet, and which is built on a permanent chassis and designed to be
used as a dwelling with or without a permanent foundation when connected to the
required utilities, and includes the plumbing, heating, air conditioning, and
electrical systems contained therein; except that such term shall include any
structure which meets all the requirements of [this] paragraph except the size
requirements and with respect to which the manufacturer voluntarily files a
certification required by the Secretary of Housing and Urban Development and
complies with the standards established under [this] chapter.'
 
     The related Prospectus Supplement will specify for the Contracts contained
in the related Trust, among other things, the date of origination of the
Contracts; the Mortgage Rates or the APRs on the Contracts; the Contract
Loan-to-Value Ratios; the minimum and maximum outstanding principal balances as
of the Statistic Calculation Date and the average outstanding principal balance;
the outstanding principal balances of the Contracts included in the related
Trust; and the original maturities of the Contracts and the last maturity date
of any Contract.

                               THE MORTGAGE POOLS
 
GENERAL
 
     Unless otherwise specified in the related Prospectus Supplement, each
Mortgage Pool will consist primarily of (i) conventional Mortgage Loans, minus
any stripped portion of the interest payments due under the related Mortgage
Note that may have been retained by any Originator or broker ('Originator's
Retained Yield'), or any other interest retained by the Sponsor or any affiliate
of the Sponsor, evidenced by promissory notes (the 'Mortgage Notes') secured by
mortgages or deeds of trust or other similar security instruments creating a
lien on single-family (i.e., one- to four-family) residential, multi-family
properties or mixed use properties, or (ii) certificates of interest or
participations in such Mortgage Notes. The Mortgaged Properties will consist
primarily of attached or detached one-family dwelling units, two- to four-family
dwelling units, condominiums, townhouses, row houses, individual units in
planned-unit developments and certain other dwelling units, mixed use properties
and the fee, leasehold or other interests in the underlying real property. The
Mortgaged Properties may be owner-occupied (which includes second and vacation
homes) and non-owner occupied investment properties. If specified in the related
Prospectus Supplement relating to a series of Securities, a Mortgage Pool may
contain cooperative apartment loans ('Cooperative Loans') evidenced by
promissory notes ('Cooperative Notes') secured by security interests in shares
issued by cooperatives and in the related proprietary leases or occupancy
agreements granting exclusive rights to occupy specific dwelling units in the
related buildings. As used herein, unless the context indicates otherwise,
'Mortgage Loans' include Cooperative Loans, 'Mortgaged Properties' include
shares in the related cooperative and the related proprietary leases or
occupancy agreements securing Cooperative Notes, 'Mortgage Notes' include

Cooperative Notes and 'Mortgages' include security agreements with respect to
Cooperative Notes.
 
     Each Mortgage Loan will be selected by the Sponsor for inclusion in a
Mortgage Pool from among mortgage loans originated by one or more institutions
affiliated with the Sponsor (such affiliated institutions, the 'Affiliated
Originators'), or from banks, savings and loan associations, mortgage bankers,
mortgage brokers, investment banking firms, the RTC, the FDIC and other mortgage
loan originators or purchasers not affiliated with the Sponsor (such
unaffiliated institutions, the 'Unaffiliated Originators' and, collectively with
the Affiliated Originators, the 'Originators'), all as described below under
'Mortgage Loan Program.' The characteristics of the Mortgage Loans will be
described in the related Prospectus Supplement. Other mortgage loans available
for acquisition by a Trust may have characteristics that would make them
eligible for inclusion in a Mortgage Pool but may not be selected by the Sponsor
for inclusion in such Mortgage Pool.
 
     Each Security will evidence an interest in only the related Mortgage Pool
and corresponding Trust Estate, and not in any other Mortgage Pool or any other
Trust Estate (except in those limited situations whereby certain collections on
any Mortgage Loans in a related Mortgage Pool in excess of amounts needed to pay
the related securities may be deposited in a common, master reserve account that
provides Credit Enhancement for more than one series of Securities).
 
THE MORTGAGE POOLS
 
     Unless otherwise specified below or in the related Prospectus Supplement,
all of the Mortgage Loans in a Mortgage Pool will (i) have payments that are due
monthly or bi-weekly, (ii) be secured by Mortgaged Properties located in any of
the fifty states, the District of Columbia, Puerto Rico or any other Territories
of the United States and (iii) consist of one or more of the following types of
mortgage loans:
 
          (1) Fixed-rate, fully-amortizing mortgage loans (which may include
     mortgage loans converted from adjustable-rate mortgage loans or otherwise
     modified) providing for level monthly payments of principal and interest
     and terms at origination or modification of generally not more than 30
     years;
 
          (2) ARM Loans having original or modified terms to maturity of
     generally not more than 30 years with a related Mortgage Rate that adjusts
     periodically, at the intervals described in the related Prospectus
     Supplement (which may have adjustments in the amount of monthly payments at
     periodic intervals) over the term of the mortgage loan to equal the sum of
     a fixed percentage set forth in the related Mortgage Note (the
 
                                       25
<PAGE>
     'Note Margin') and an index (the 'Index') to be specified in the related
     Prospectus Supplement, such as, by way of example: (i) U.S. Treasury
     securities of a specified constant maturity, (ii) weekly auction average
     investment yield of U.S. Treasury bills of specified maturities, (iii) the
     daily Bank Prime Loan rate made available by the Federal Reserve Board or
     as quoted by one or more specified lending institutions, (iv) the cost of

     funds of member institutions for the Federal Home Loan Bank of San
     Francisco, or (v) the interbank offered rates for U.S. dollar deposits in
     the London Markets, each calculated as of a date prior to each scheduled
     interest rate adjustment date that will be specified in the related
     Prospectus Supplement. The related Prospectus Supplement will set forth the
     relevant Index, and the related Prospectus Supplement or the related
     Current Report on Form 8-K will indicate the highest, lowest and
     weighted-average Note Margin with respect to the ARM Loans in the related
     Mortgage Pool. If specified in the related Prospectus Supplement, an ARM
     Loan may include a provision that allows the Mortgagor to convert the
     adjustable Mortgage Rate to a fixed rate at some point during the term of
     such ARM Loan subsequent to the initial payment date;
 
          (3) Fixed-rate, graduated payment mortgage loans having original or
     modified terms to maturity of generally not more than 30 years with monthly
     payments during the first year calculated on the basis of an assumed
     interest rate that will be lower than the Mortgage Rate applicable to such
     mortgage loan in subsequent years. Deferred Interest, if any, will be added
     to the principal balance of such mortgage loans;
 
          (4) Balloon mortgage loans ('Balloon Loans'), which are mortgage loans
     having original or modified terms to maturity of generally 5 to 15 years as
     described in the related Prospectus Supplement, which may have level
     monthly payments of principal and interest based generally on a 10- to
     30-year amortization schedule. The amount of the monthly payment may remain
     constant until the maturity date, upon which date the full outstanding
     principal balance on such Balloon Loan will be due and payable (such
     amount, the 'Balloon Amount');
 
          (5) Modified mortgage loans ('Modified Loans'), which are fixed or
     adjustable-rate mortgage loans providing for terms at the time of
     modification of generally not more than 30 years. Modified Loans may be
     mortgage loans which have been consolidated and/or have had various terms
     changed, mortgage loans which have been converted from adjustable rate
     mortgage loans to fixed rate mortgage loans, or construction loans which
     have been converted to permanent mortgage loans;
 
          (6) Another type of mortgage loan described in the related Prospectus
     Supplement; or
 
          (7) As more fully described in the related Prospectus Supplement, the
     Mortgage Loans may consist, in whole or in part, of Revolving Credit Line
     Loans. Interest on each Revolving Credit Line Loan, excluding introductory
     rates offered from time to time during promotional periods, may be computed
     and payable monthly on the average daily outstanding principal balance of
     such loan. From time to time prior to the expiration of the related draw
     period specified in a Revolving Credit Line Loan, principal amounts on such
     Revolving Credit Line Loan may be drawn down (up to a maximum amount as set
     forth in the related Prospectus Supplement) or repaid. If specified in the
     related Prospectus Supplement, new draws by borrowers under the Revolving
     Credit Line Loans will automatically become part of the Trust Estate
     described in such Prospectus Supplement. As a result, the aggregate balance
     of the Revolving Credit Line Loans will fluctuate from day to day as new
     draws by borrowers are added to the Trust Estate and principal payments are

     applied to such balances and such amounts will usually differ each day, as
     more specifically described in the related Prospectus Supplement. Under
     certain circumstances, under a Revolving Credit Line Loan, a borrower may,
     during the related draw period, choose an interest only payment option,
     during which the borrower is obligated to pay only the amount of interest
     which accrues on the loan during the billing cycle, and may also elect to
     pay all or a portion of the principal. An interest only payment option may
     terminate at the end of the related draw period, after which the borrower
     must begin paying at least a minimum monthly portion of the average
     outstanding principal balance of the loan.
 
     If provided for in the related Prospectus Supplement, a Mortgage Pool may
contain either or both of the following types of mortgage loans (i) ARM Loans
which allow the Mortgagors to convert the adjustable rates on such Mortgage
Loans to a fixed rate at some point during the life of such Mortgage Loans and
(ii) fixed rate mortgage loans which allow the Mortgagors to convert the fixed
rates on such Mortgage Loans to an adjustable
 
                                       26
<PAGE>
rate at some point during the life of such Mortgage Loans (each such Mortgage
Loan described in (i) and (ii) above, a 'Convertible Mortgage Loan').
 
     If provided for in the related Prospectus Supplement, certain of the
Mortgage Loans may be Buydown Mortgage Loans pursuant to which the monthly
payments made by the Mortgagor during the Buydown Period will be less than the
scheduled monthly payments on the Mortgage Loan, the resulting difference to be
made up from (i) Buydown Funds funded by the Originator of the Mortgaged
Property or another source (including the Master Servicer or the related
Originator) and placed in the Buydown Account and (ii) if the Buydown Funds are
contributed on a present value basis, investment earnings on such Buydown Funds.
See 'Description of the Securities--Payments on Mortgage Loans; Deposits to
Distribution Account.' The terms of the Buydown Mortgage Loans, if such loans
are included in a Trust, will be as set forth in the related Prospectus
Supplement.
 
     The Sponsor will cause the Mortgage Loans constituting each Mortgage Pool
to be assigned to the Trustee named in the related Prospectus Supplement, for
the benefit of the holders of all of the Securities of a series. The Master
Servicer named in the related Prospectus Supplement will service the Mortgage
Loans, either directly or through other mortgage servicing institutions
(Sub-Servicers), pursuant to a Pooling and Servicing Agreement and will receive
a fee for such services. See 'Mortgage Loan Program' and 'Description of the
Securities.' With respect to those Mortgage Loans serviced by the Master
Servicer through a Sub-Servicer, the Master Servicer will remain liable for its
servicing obligations under the related Pooling and Servicing Agreement as if
the Master Servicer alone were servicing such Mortgage Loans, unless otherwise
described in the related Prospectus Supplement.
 
     The Sponsor and/or certain Originators may make certain representations and
warranties regarding the Mortgage Loans, but its assignment of the Mortgage
Loans to the Trustee will be without recourse. See 'Description of the
Securities--Assignment of Mortgage Loans.' The Master Servicer's obligations
with respect to the Mortgage Loans will consist principally of its contractual

servicing obligations under the related Pooling and Servicing Agreement
(including its obligation to enforce certain purchase and other obligations of
Sub-Servicers and of Originators, as more fully described herein under 'Mortgage
Loan Program--Representations by Originators,' '--Sub-Servicing by Originators'
and 'Description of the Securities--Assignment of Mortgage Loans,' and its
obligation, if any, to make certain cash advances in the event of delinquencies
in payments on or with respect to the Mortgage Loans and interest shortfalls due
to prepayment of Mortgage Loans, in amounts described herein under 'Description
of the Securities--Advances'). The obligation of the Master Servicer to make
delinquency advances will be limited to the extent, in its good faith business
judgment such delinquency advances would be ultimately recoverable from the
proceeds of liquidation of the Mortgage Loans. See 'Description of the
Securities--Advances.'
 
                             MORTGAGE LOAN PROGRAM
 
     As a general matter, the Sponsor's Mortgage Loan program will consist of
the origination and packaging of Mortgage Loans relating to non-conforming
credits. For purposes hereof, 'non-conforming credit' means a mortgage loan
which, based upon standard underwriting guidelines, is ineligible for purchase
by FNMA or FHLMC due to credit characteristics that do not meet FNMA or FHLMC
guidelines, respectively. However, certain of the Mortgage Loans will relate to
FNMA or FHLMC conforming credits.
 
     The Mortgagors generally will have taken out the related Mortgage Loans for
one or more of four reasons: (i) to purchase the related Mortgaged Property,
(ii) to refinance an existing mortgage loan on more favorable terms, (iii) to
consolidate debt, or (iv) to obtain cash proceeds by borrowing against the
Mortgagor's equity in the related Mortgaged Property; the Mortgage Loans
described in (i) are commonly referred to as purchase money loans and the
Mortgage Loans described in (ii), (iii) and (iv) on the whole are commonly
referred to as home equity loans.
 
     It is the Sponsor's practice to solicit existing Mortgagors with respect to
the possible refinancing of their existing Mortgages.
 
                                       27

UNDERWRITING GUIDELINES
 
     As more fully described below under 'Qualifications of Originators' and as
may also be described in greater detail in the related Prospectus Supplement,
there are various types of Originators that may participate in the Sponsor's
Mortgage Loan Program. Under the Sponsor's Mortgage Loan Program, the Sponsor
purchases and originates Mortgage Loans pursuant to three types of underwriting
guidelines: (1) standard underwriting guidelines according to the Sponsor's
Originator Guide, as modified from time to time, used by Affiliated Originators
and Unaffiliated Originators ('Sponsor's Guidelines'), (2) underwriting
guidelines utilized by certain Unaffiliated Originators and approved by the
Sponsor ('Approved Guidelines'), and (3) underwriting guidelines ('Bulk
Guidelines') used by Unaffiliated Originators of portfolios of Mortgage Loans
subsequently purchased in whole or part by the Sponsor as bulk acquisitions
('Bulk Acquisitions'). The respective underwriting guidelines are described
below.

 
     Sponsor's Guidelines.  The Sponsor's Guidelines are set forth in the
Sponsor's Originator Guide. The Sponsor's Guidelines are revised continuously
based on opportunities and prevailing conditions in the nonconforming credit
residential mortgage market, as well as the expected market for the resulting
Securities.
 
     Mortgage Loans originated by Affiliated Originators generally will, and
Mortgage Loans originated by Unaffiliated Originators may have been, originated
in accordance with the Sponsor's Guidelines as set forth in the Sponsor's
Originator Guide. However, certain of the Mortgage Loans may be employee or
preferred customer loans with respect to which, in accordance with such
Affiliate's mortgage loan programs, no income or asset verifications were
required. In addition, certain Originators may originate Mortgage Loans in
satisfaction of specified requirements of federal or state law applicable to
certain Originators, such as, by way of illustration, the federal Community
Reinvestment Act of 1977, which is applicable to banks; such Mortgage Loans
generally will not have been originated pursuant to the Sponsor's standard
underwriting guidelines applicable to nonconforming loans but may have been
originated pursuant to alternative guidelines applicable to such loans. The
Sponsor will not review any Affiliated Originator mortgage loans for conformity
with the Sponsor's Guidelines set forth in the Sponsor's Originator Guide. The
Sponsor generally will review or cause to be reviewed only a limited portion of
the Mortgage Loans in any delivery of Mortgage Loans from Unaffiliated
Originators for conformity with the Sponsor's Originator Guide.
 
     The following is a brief description of the Sponsor's Guidelines set forth
in the Sponsor's Originator Guide customarily and currently employed by the
Sponsor. The Sponsor believes that these standards are consistent with those
generally used by lenders in the business of making mortgage loans based on
non-conforming credits. The underwriting process is intended to assess both the
prospective borrower's ability to repay and the adequacy of the real property as
collateral for the loan granted. The general appreciation in value of real
estate experienced in the past has been a factor in limiting the Master
Servicer's loss experience on its portfolio of one- to four-family residential
mortgage loans. However, the past pattern of appreciation in value of the real
property securing such loans has not continued, and a depreciation in value has
occurred and may continue to occur in some market areas, and may occur in
others.
 
     The Sponsor's Guidelines permit the origination and purchase of mortgage
loans with multi-tiered credit characteristics tailored to individual credit
profiles. In general, the Sponsor's Guidelines require an analysis of the equity
in the collateral, the payment history of the borrower, the borrower's ability
to repay debt, the property type, and the characteristics of the underlying
first mortgage, if any. A lower maximum CLTV is required for lower gradations of
credit quality and higher property values.
 
     The Sponsor's Guidelines permit the origination or purchase of fixed or
adjustable rate loans that either fully amortize over a period generally not to
exceed 30 years or, in the case of a balloon mortgage, generally amortize based
on a 30-year or less amortization schedule with a due date and a 'balloon'
payment due prior to the 30 year period.
 

     The homes used for collateral to secure the loans may be either owner
occupied (which includes second and vacation homes) or non-owner occupied
investor properties which, in either case are single-family residences (which
may be detached, part of a two- to four-family dwelling, a condominium unit or a
unit in a planned unit development). The Sponsor's Guidelines require that the
CLTV of a Mortgage Loan generally not exceed 85%, after taking into account the
amount of any primary mortgage insurance applicable to such Mortgage Loan.
 
                                       28
<PAGE>
     If a senior mortgage exists, the lender may first review the senior
mortgage documentation. If it contains open end advance or negative amortization
provisions, the maximum potential senior mortgage balance may be used, although
for certain of the Sponsor's products the current balance may be used in
calculating the CLTV which determines the maximum loan amount. The Sponsor's
Guidelines do not permit the origination or purchase of loans where the senior
mortgage contains a provision pursuant to which the senior mortgagee may share
in any appreciation of the Mortgaged Property.
 
     In most cases, the value of each property proposed as security for a
mortgage loan is required to be determined by a full appraisal. A limited
appraisal of a property, conducted on a drive-by basis, may be utilized. Two
full appraisals are generally required for properties valued over $500,000.
 
     Appraisals are required to be completed by qualified professional
appraisers. The Sponsor evaluates the performance of appraisers and maintains a
current disapproved appraiser list.
 
     The Sponsor's Guidelines have provided for the origination of loans under
three general loan programs: (i) a full verification program for salaried or
self-employed borrowers, (ii) a 'lite' documentation program for borrowers who
may have income which cannot be verified by traditional methods and (iii) a
non-income verification program for self-employed borrowers only. However, the
Sponsor's Guidelines allow for certain borrowers with existing loans to
refinance such loans with either limited, or no, verification of income. The
Sponsor may also purchase pools of loans which may include some loans originated
under a non-income verification program. For the Sponsor's full verification
process, each mortgage applicant is required to provide, and the Sponsor or its
designee is required to verify, personal financial information. The applicant's
total monthly obligations (including principal and interest on each mortgage,
tax assessments, other loans, charge accounts and all other scheduled
indebtedness) generally (in the absence of countervailing considerations, such
as a lower Combined Loan-to-Value Ratio or a price adjustment) should not exceed
the applicant's ability to pay. Applicants who are salaried employees must
provide current employment information in addition to recent employment history.
The Sponsor or its designee verify this information for salaried borrowers based
on written confirmation from employers or a combination of the most recent pay
stub, the most recent W-2 tax form and telephone confirmation from the employer.
Self-employed applicants are generally required to be self-employed in the same
field for a minimum of two years. The self-employed applicant is generally
required to provide personal and business financial statements and signed copies
of complete federal income tax returns (including schedules) filed for the most
recent two years. For the Sponsor's 'lite' documentation program the borrower
must establish proof of cash flow trends to support the borrower's income. Such

proof can include business bank statements or personal bank statements. For the
Sponsor's non-income verifier program, proof of two year's history of
self-employment plus proof of current self-employed status is required. The
applicant's debt-to-income ratio is calculated based on income as certified by
the borrower on the application and must be reasonable.
 
     A credit report by an independent, nationally recognized credit reporting
agency is required reflecting the applicant's complete credit history. The
credit report should reflect all delinquencies of 30 days or more,
repossessions, judgments, foreclosures, garnishments, bankruptcies and similar
instances of adverse credit that can be discovered by a search of public
records. Verification is required to be obtained of the senior mortgage balance,
if any, the status and whether local taxes, interest, insurance and assessments
are included in the applicant's monthly payment. All taxes and assessments not
included in the payment are required to be verified as current.
 
     In connection with purchase-money loans, the Sponsor's Guidelines require
(x) (i) an acceptable source of downpayment funds, (ii) verification of the
source of the downpayment funds and (iii) adequate cash reserves or (y) adequate
equity in the collateral property.
 
     Certain laws protect loan applicants by offering them a time frame after
loan documents are signed, termed the rescission period, during which the
applicant has the right to cancel the loan. The rescission period must have
expired prior to funding a loan and may not be waived by the applicant except as
permitted by law.
 
     Unless otherwise disclosed in the related Prospectus Supplement, the
Sponsor's Guidelines generally require title insurance coverage issued by an
approved ALTA or CLTA title insurance company on each Mortgage Loan it
purchases. The Sponsor, the related Originator and/or their assignees generally
are named as the insured. Title
 
                                       29
<PAGE>
insurance policies indicate the lien position of the mortgage loan and protect
the insured against loss if the title or lien position is not as indicated.
 
     The applicant is required to secure property insurance in an amount
sufficient to cover the new loan and any prior mortgage. If the sum of the
outstanding first mortgage, if any, and the related mortgage loan exceeds
replacement value (the cost of rebuilding the subject property, which generally
does not include land value), insurance equal to replacement value may be
accepted. The Sponsor or its designee is required to ensure that its name and
address is properly added to the 'Mortgagee Clause' of the insurance policy. In
the event the Sponsor or the related Originator's name is added to a 'Loss Payee
Clause' and the policy does not provide for written notice of policy changes or
cancellation, an endorsement adding such provision is required.
 
     Approved Guidelines.  The Sponsor may cause a Trust to acquire Mortgage
Loans underwritten pursuant to underwriting guidelines that may differ from the
Sponsor's Guidelines as set forth in the Sponsor's Originator Guide. Certain of
the Mortgage Loans will be acquired in negotiated transactions, and such
negotiated transactions may be governed by agreements ('Master Commitments')

relating to ongoing acquisitions of Mortgage Loans by the Sponsor, from
Originators who will represent that the Mortgage Loans have been originated in
accordance with underwriting guidelines agreed to by the Sponsor. Certain other
Mortgage Loans will be acquired from Originators that will represent that the
Mortgage Loans were originated pursuant to underwriting guidelines determined by
a mortgage insurance company acceptable to the Sponsor. The Sponsor will accept
a certification from such insurance company as to a Mortgage Loan's insurability
in a mortgage pool as of the date of certification as evidence of a Mortgage
Loan conforming to applicable underwriting standards. Such certifications likely
will have been issued before the purchase of the Mortgage Loan by the Sponsor.
The Sponsor only will perform random quality assurance reviews on Mortgage Loans
delivered with such certifications.
 
     The underwriting standards utilized in negotiated transactions and Master
Commitments and the underwriting standards of insurance companies may vary
substantially from the Sponsor's Guidelines. All of the underwriting guidelines
will provide an underwriter with information to evaluate either the security for
the related Mortgage Loan, which security consists primarily of the borrower's
repayment ability or the adequacy of the Mortgaged Property as collateral, or a
combination of both. Due to the variety of underwriting guidelines and review
procedures that may be applicable to the Mortgage Loans included in any Mortgage
Pool, the related Prospectus Supplement will not distinguish among the various
underwriting guidelines applicable to the Mortgage Loans nor describe any review
for compliance with applicable underwriting guidelines performed by the Sponsor.
Moreover, there can be no assurance that every Mortgage Loan was originated in
conformity with the Approved Guidelines in all material respects, or that the
quality or performance of Mortgage Loans underwritten pursuant to varying
guidelines as described above will be equivalent under all circumstances.
 
     Bulk Guidelines.  Bulk portfolios of Mortgage Loans may be originated by a
variety of Originators under several different underwriting guidelines. For bulk
portfolios which are seasoned for a period of time, the Sponsor's underwriting
review of bulk portfolios of Mortgage Loans focuses primarily on payment
histories and estimated current values based on estimated property appreciation
or depreciation and loan amortization. Mortgage Loans that conform to the
related Bulk Guidelines may not conform to the requirements of either the
Sponsor's Guidelines or the Approved Guidelines. For example, the Sponsor may
purchase Mortgage Loans in bulk portfolios with Combined Loan-to-Value Ratios in
excess of that required under the Sponsor's Guidelines, without title insurance,
or with nonconforming appraisal methods such as tax assessments. Bulk
Acquisition portfolios may be purchased servicing released or retained. If
servicing is retained, the Originator must meet certain minimum requirements, as
modified from time to time, by the Sponsor. The Sponsor generally will cause the
Mortgage Loans acquired in a Bulk Acquisition to be reunderwritten on a sample
basis. Such reunderwriting may be performed by the Sponsor, the Master Servicer
or by a third party acting at the direction of the Sponsor.
 
     Quality Control.  The Master Servicer maintains a quality control
department which generally reviews loans originated by Affiliated Originators.
The quality control department randomly selects a portion of the files for
underwriting review. The Sponsor or its Affiliated Originators also cause
appraisal reviews to be performed on a random sample of loan production.
 
     A periodic report is distributed to senior management and the production

offices describing material exceptions to underwriting and appraisal guidelines,
legal and regulatory requirements and variances based on the
 
                                       30
<PAGE>
reverification process. Appraisers demonstrating chronic errors, omissions or
large valuation errors are removed from the approved appraiser list. Training
programs, additional audits and performance evaluations for underwriting
personnel and management are influenced by the results of the quality control
review.
 
     The Sponsor generally will cause Mortgage Loans acquired from Unaffiliated
Originators to be (i) reunderwritten for the purpose of determining whether such
Mortgage Loans were originated in accordance with the applicable underwriting
guidelines, (ii) reviewed to assess the accuracy of the appraised values, and
(iii) audited to determine the accuracy of the loan computer system as compared
to the loan files. Such process may consist of a review of all such Mortgage
Loans or may be performed on a sample basis. Such reunderwriting may be
performed by the Sponsor, the Master Servicer or a third party acting at the
direction of the Sponsor.
 
QUALIFICATIONS OF ORIGINATORS
 
     Each Originator from which a Mortgage Loan is acquired will have been
accepted by the Sponsor for participation in the Sponsor's mortgage loan
program. Certain Unaffiliated Originators ('Conduit Participants') may be
qualified to enter into agreements to sell mortgage loans to the Sponsor
pursuant to Master Commitments which provide for the periodic purchase and sale
of loans meeting certain specified requirements.
 
     Loans acquired from Unaffiliated Originators other than Conduit
Participants will be acquired on a 'spot' basis, or in connection with a Bulk
Acquisition. Unless otherwise described in the related Prospectus Supplement
with respect to certain specified Unaffiliated Originators (in which case any
remedies for breach will lie only against such Unaffiliated Originator), the
Sponsor will make directly, or will guarantee compliance with, any
representations and warranties made by any Unaffiliated Originator, with respect
to the Mortgage Loans originated by it and acquired by a Trust.
 
     All Conduit Participants must have received a satisfactory review by the
Sponsor of its operating procedures. All Unaffiliated Originators will have
delinquency and foreclosure rates monitored and maintained at levels acceptable
to the Sponsor. All Unaffiliated Originators are required to originate mortgage
loans in accordance with the applicable underwriting standards. However, with
respect to any Originator, some of the generally applicable underwriting
standards described herein and in the Sponsor's Originator Guide may be modified
or waived with respect to certain Mortgage Loans originated by such Originators.
 
     The Resolution Trust Corporation (the 'RTC') or the Federal Deposit
Insurance Corporation (the 'FDIC') (either in their respective corporate
capacities or as receiver or conservator for a depository institution) may also
be an Originator of the Mortgage Loans. The RTC and the FDIC are together
referred to as the 'Federal Corporations'. The RTC was established pursuant to
the Financial Institutions Reform, Recovery, and Enforcement Act of 1989

('FIRREA'), which was enacted in response to the financial crisis of the thrift
industry and the Federal Savings and Loan Insurance Corporation. The purpose of
FIRREA is to restore the public's confidence in the savings and loan industry in
order to ensure a viable system of affordable housing finance as well as to
improve the supervision of savings associations and promote the independence of
the FDIC. The FDIC is an independent executive agency originally established by
the Banking Act of 1933 to insure the deposits of all banks entitled to federal
deposit insurance under the Federal Reserve Act and Federal Deposit Insurance
Act. The FDIC administers the system of nationwide deposit insurance (mutual
guaranty of deposits) for United States Banks and, together with the United
States Comptroller of the Currency, regulates in areas related to the
maintenance of reserves for certain types of deposits, the maintenance of
certain financial ratios, transactions with affiliates and a broad range of
other banking practices.
 
     The Sponsor monitors the Originators and the Sub-Servicers under the
control of a Federal Corporation, as well as those Originators and Sub-Servicers
that are insolvent or in receivership or conservatorship or otherwise
financially distressed. Such Originators may not be able or permitted to
repurchase Mortgage Loans for which there has been a breach of representation
and warranty. Moreover, any such Originator may make no representations and
warranties with respect to Mortgage Loans sold by it. The Federal Corporations
(either in their respective corporate capacities or as receiver for a depository
institution) may also originate Mortgage Loans, in which event neither the
related Federal Corporation nor the depository institution for which such
Federal Corporation is acting as receiver may make representations and
warranties with respect to the Mortgage Loans that such Federal Corporation
sells, or such Federal Corporation may make only limited representations and
warranties (for example, that the related legal documents are enforceable). A
Federal Corporation may have
 
                                       31
<PAGE>
no obligation to repurchase any Mortgage Loan for a breach of a representation
and warranty. If as a result of a breach of representation and warranty an
Originator is required to repurchase a Mortgage Loan but is not permitted or
otherwise fails to do so or if representations and warranties are not made by an
Originator, to the extent that neither the Sponsor nor any other entity has
assumed the representations and warranties or made representations and
warranties, neither the Sponsor nor that entity will be required to repurchase
such Mortgage Loan and, consequently such Mortgage Loan will remain in the
related Mortgage Pool and any related losses will be borne by the
Securityholders or by the related Credit Enhancement, if any. In addition, loans
which are purchased either directly or indirectly from a Federal Corporation may
be subject to a contract right of such Federal Corporation to repurchase such
loans under certain limited circumstances.
 
SUB-SERVICERS
 
     Each Originator of a Mortgage Loan will act as Sub-Servicer for such
Mortgage Loan pursuant to an agreement between the Master Servicer and the
Sub-Servicer (a 'Sub-Servicing Agreement') unless the servicing obligations are
released to the Master Servicer or transferred to a servicer approved by the
Master Servicer. An Affiliated Originator of a Mortgage Loan may act as the

Sub-Servicer for such Mortgage Loan unless the other related servicing
obligations are released or transferred. An Unaffiliated Originator acting as a
Sub-Servicer for the Mortgage Loans will be required to meet certain additional
standards with respect to its mortgage loan servicing portfolio, GAAP tangible
net worth and other specified qualifications.
 
REPRESENTATIONS BY ORIGINATORS
 
     Unless otherwise specified in the related Prospectus Supplement, each
Originator will have made representations and warranties in respect of the
Mortgage Loans sold by such Originator and evidenced by a series of Securities.
Such representations and warranties generally include, among other things, that
at the time of the sale by the Originator to the Sponsor of each Mortgage Loan:
(i) the information with respect to each Mortgage Loan set forth in the
Schedules of Mortgage Loans is true and correct as of the related Cut-Off Date;
(ii) each Mortgage Loan being transferred to the Trust which is a REMIC is a
qualified mortgage under the REMIC provisions of the Code and is a Mortgage;
(iii) each Mortgaged Property is improved by a single (one- to four-) family
residential dwelling or a multi-family structure, which may include condominiums
and townhouses; (iv) each Mortgage Loan had, at the time of origination, either
an attorney's certification of title or a title search or title policy; (v) as
of the related Cut-Off Date each Mortgage Loan is secured by a valid and
subsisting lien of record on the Mortgaged Property having the priority
indicated on the related Schedule of Mortgage Loans subject in all cases to
exceptions to title set forth in the title insurance policy, if any, with
respect to the related Mortgage Loan; (vi) each Originator held good and
indefeasible title to, and was the sole owner of, each Mortgage Loan conveyed by
such Originator; and (vii) each Mortgage Loan was originated in accordance with
law and is the valid, legal and binding obligation of the related Mortgagor.
 
     Unless otherwise described in the related Prospectus Supplement, all of the
representations and warranties of an Originator in respect of a Mortgage Loan
will be made as of the date on which such Originator sells the Mortgage Loan to
the Sponsor; the date as of which such representations and warranties are made
thus may be a date prior to the date of the issuance of the related series of
Securities. A substantial period of time may elapse between the date as of which
the representations and warranties are made and the later date of issuance of
the related series of Securities.
 
     The Sponsor will assign to the Trustee for the benefit of the holders of
the related series of Securities all of its right, title and interest in each
agreement by which it acquires a Mortgage Loan from an Originator insofar as
such agreement relates to the representations and warranties made by an
Originator in respect of such Mortgage Loan and any remedies provided for breach
of such representations and warranties. If an Originator cannot cure a breach of
any representation or warranty made by it in respect of a Mortgage Loan that
materially and adversely affects the interests of the Securityholders in such
Mortgage Loan within a time period specified in the related Pooling and
Servicing Agreement, such Originator and/or the Sponsor will be obligated to
purchase from the related Trust such Mortgage Loan at a price (the 'Loan
Purchase Price') set forth in the related Pooling and Servicing Agreement which
Loan Purchase Price will be equal to the principal balance thereof as of the
date of purchase plus one month's interest at the Mortgage Rate less the amount,
expressed as a percentage per annum, payable in respect of master servicing

compensation or subservicing compensation, as applicable, and the
 
                                       32
<PAGE>
Originator's Retained Yield, if any, together with, without duplication, the
aggregate amount of all delinquent interest, if any, net of Servicing Advances.
 
     Unless otherwise specified in the related Prospectus Supplement, as to any
such Mortgage Loan required to be purchased by an Originator and/or the Sponsor,
as provided above, rather than repurchase the Mortgage Loan, the Master Servicer
may, at its sole option, remove such Mortgage Loan (a 'Deleted Mortgage Loan')
from the related Trust and cause the Sponsor to substitute in its place another
Mortgage Loan of like kind (a 'Qualified Replacement Mortgage' as such term is
defined in the related Pooling and Servicing Agreement). With respect to a Trust
for which a REMIC election is to be made, except as otherwise provided in the
Prospectus Supplement relating to a series of Securities, such substitution of a
defective Mortgage Loan must be effected within two years of the date of the
initial issuance of the Securities, and may not be made if such substitution
would cause the Trust to not qualify as a REMIC or result in a prohibited
transaction tax under the Code. Unless otherwise specified in the related
Prospectus Supplement or Pooling and Servicing Agreement, an Unaffiliated
Originator generally will have no option to substitute for a Mortgage Loan that
it is obligated to repurchase in connection with a breach of a representation
and warranty.
 
     The Master Servicer will be required under the applicable Pooling and
Servicing Agreement to enforce such purchase or substitution obligations for the
benefit of the Trustee and the Securityholders, following the practices it would
employ in its good faith business judgment if it were the owner of such Mortgage
Loan; provided, however, that this purchase or substitution obligation will in
no event become an obligation of the Master Servicer in the event the Originator
fails to honor such obligation. If the Originator fails to repurchase or
substitute a loan and no breach of the Sponsor's representations has occurred,
the Originator's purchase obligation will in no event become an obligation of
the Sponsor. Unless otherwise specified in the related Prospectus Supplement,
the foregoing will constitute the sole remedy available to Securityholders or
the Trustee for a breach of representation by an Originator in its capacity as a
seller of Mortgage Loans to the Sponsor.
 
     Unless otherwise described in the related Prospectus Supplement with
respect to certain Unaffiliated Originators (in which case any remedies for
breach will lie only against such Unaffiliated Originator), the Sponsor will
make directly, or will guarantee compliance with, any representations and
warranties made by any Unaffiliated Originator with respect to the Mortgage
Loans originated or purchased by it and acquired by a Trust.
 
     Notwithstanding the foregoing with respect to any Originator that requests
the Master Servicer's consent to the transfer of sub-servicing rights relating
to any Mortgage Loans to a successor servicer, the Master Servicer may release
such Originator from liability, under its representations and warranties
described above, upon the assumption by such successor servicer of the
Originator's liability for such representations and warranties as of the date
they were made. In that event, the Master Servicer's rights under the instrument
by which such successor servicer assumes the Originator's liability will be

assigned to the Trustee, and such successor servicer shall be deemed to be the
'Originator' for purposes of the foregoing provisions.
 
SUB-SERVICING BY ORIGINATORS
 
     Each Originator of a Mortgage Loan will act as the Sub-Servicer for such
Mortgage Loan pursuant to a Sub-Servicing Agreement unless servicing is released
to the Master Servicer or has been transferred to a servicer approved by the
Master Servicer. The Master Servicer may, in turn, assign such sub-servicing to
designated sub-servicers that will be qualified Originators and may include
affiliates of the Sponsor. While such a Sub-Servicing Agreement will be a
contract solely between the Master Servicer and the Sub-Servicer, the Pooling
and Servicing Agreement pursuant to which a series of Securities is issued will
provide that, if for any reason the Master Servicer for such series of
Securities is no longer the master servicer of the related Mortgage Loans, the
Trustee or any successor Master Servicer must recognize the Sub-Servicer's
rights and obligations under such Sub-Servicing Agreement.
 
     Unless otherwise specified in the related Prospectus Supplement, with the
approval of the Master Servicer, a Sub-Servicer may delegate its servicing
obligations to third-party servicers, but such Sub-Servicer will remain
obligated under the related Sub-Servicing Agreement. Each Sub-Servicer will be
required to perform the customary functions of a servicer, including collection
of payments from Mortgagors and remittance of such collections to the Master
Servicer; maintenance of hazard insurance and filing and settlement of claims
thereunder, subject in certain cases to the right of the Master Servicer to
approve in advance any such settlement;
 
                                       33
<PAGE>
maintenance of escrow or impound accounts of Mortgagors for payment of taxes,
insurance and other items required to be paid by the Mortgagor pursuant to the
Mortgage Loan; processing of assumptions or substitutions; attempting to cure
delinquencies; supervising foreclosures; inspecting and managing Mortgaged
Properties under certain circumstances; and maintaining accounting records
relating to the Mortgage Loans. A Sub-Servicer also may be obligated to make
advances to the Master Servicer in respect of delinquent installments of
principal and/or interest (net of any sub-servicing or other compensation) on
Mortgage Loans, as described more fully under 'Description of the
Securities--Advances,' and in respect of certain taxes and insurance premiums
not paid on a timely basis by Mortgagors. A Sub-Servicer may also be obligated
to deposit amounts in respect of Compensating Interest to the related Principal
and Interest Account in connection with prepayments of principal received and
applied to reduce the outstanding principal balance of a Mortgage Loan. No
assurance can be given that the Sub-Servicers will carry out their advance or
payment obligations, if any, with respect to the Mortgage Loans. Unless
otherwise specified in the related Prospectus Supplement, a Sub-Servicer may
transfer its servicing obligations to another entity that has been approved for
participation in the Sponsor's loan purchase programs, but only with the prior
written approval of the Master Servicer.
 
     As compensation for its servicing duties, the Sub-Servicer may be entitled
to a Base Servicing Fee. The Sub-Servicer may also be entitled to collect and
retain, as part of its servicing compensation, any late charges or prepayment

penalties provided in the Mortgage Note or related instruments. The Sub-Servicer
will be entitled to reimbursement for certain expenditures that it makes,
generally to the same extent that the Master Servicer would be reimbursed under
the applicable Pooling and Servicing Agreement. See 'The Pooling and Servicing
Agreement--Servicing and Other Compensation and Payment of Expenses;
Originator's Retained Yield.'
 
     Each Sub-Servicer will be required to agree to indemnify the Master
Servicer for any liability or obligation sustained by the Master Servicer in
connection with any act or failure to act by the Sub-Servicer in its servicing
capacity. Each Sub-Servicer is required to maintain a fidelity bond and an
errors and omission policy with respect to its officers, employees and other
persons acting on its behalf or on behalf of the Master Servicer.
 
     Each Sub-Servicer will be required to service each Mortgage Loan pursuant
to the terms of the Sub-Servicing Agreement for the entire term of such Mortgage
Loan, unless the Sub-Servicing Agreement is terminated earlier by the Master
Servicer or unless servicing is released to the Master Servicer. The Master
Servicer generally may terminate a Sub-Servicing Agreement immediately upon the
giving of notice upon certain stated events, including the violation of such
Sub-Servicing Agreement by the Sub-Servicer, or following a specified period
after notice to the Sub-Servicer without cause upon payment of an amount equal
to a specified termination fee calculated as a specified percentage of the
aggregate outstanding principal balance of all mortgage loans, including the
Mortgage Loans serviced by such Sub-Servicer pursuant to a Sub-Servicing
Agreement and certain transfer fees.
 
     The Master Servicer may agree with a Sub-Servicer to amend a Sub-Servicing
Agreement. Upon termination of a Sub-Servicing Agreement, the Master Servicer
may act as servicer of the related Mortgage Loans or enter into one or more new
Sub-Servicing Agreements. If the Master Servicer acts as servicer, it will not
assume liability for the representations and warranties of the Sub-Servicer that
it replaces. If the Master Servicer enters into a new Sub-Servicing Agreement,
each new Sub-Servicer either must be an Originator, meet the standards for
becoming an Originator or have such servicing experience that is otherwise
satisfactory to the Master Servicer. The Master Servicer may make reasonable
efforts to have the new Sub-Servicer assume liability for the representations
and warranties of the terminated Sub-Servicer, but no assurance can be given
that such an assumption will occur and, in any event, if the new Sub-Servicer is
an affiliate of the Master Servicer, the liability for such representations and
warranties will not be assumed by such new Sub-Servicer. In the event of such an
assumption, the Master Servicer may in the exercise of its business judgment
release the terminated Sub-Servicer from liability in respect of such
representations and warranties. Any amendments to a Sub-Servicing Agreement or
to a new Sub-Servicing Agreement may contain provisions different from those
described above that are in effect in the original Sub-Servicing Agreements.
However, the Pooling and Servicing Agreement for each Trust Estate will provide
that any such amendment or new agreement may not be inconsistent with such
Pooling and Servicing Agreement to the extent that it would materially and
adversely affect the interests of the Securityholders.

                         DESCRIPTION OF THE SECURITIES

 
GENERAL
 
     The Securities will be issued in series. Each series of Securities (or, in
certain instances, two or more series of Securities) will be issued pursuant to
a Pooling and Servicing Agreement. The following summaries (together with
additional summaries under 'The Pooling and Servicing Agreement' below) describe
all material terms and provisions relating to the Securities common to each
Pooling and Servicing Agreement. The summaries do not purport to be complete and
are subject to, and are qualified in their entirety by reference to, all of the
provisions of the Pooling and Servicing Agreement for the related Trust and the
related Prospectus Supplement.
 
     The Securities will consist of two basic types: (i) Securities of the
fixed-income type ('Fixed-Income Securities') and (ii) Securities of the equity
participation type ('Equity Securities'). No Class of Equity Securities will be
offered pursuant to this Prospectus or any Prospectus Supplement related hereto.
Fixed-Income Securities generally will be styled as debt instruments, having a
principal balance and a specified interest rate ('Interest Rate'). Fixed-Income
Securities may be either beneficial ownership interests in the related Mortgage
Loans held by the related Trust, or may represent debt secured by such Mortgage
Loans. Each series or class of Fixed-Income Securities may have a different
Interest Rate, which may be a fixed, variable or adjustable Interest Rate. The
related Prospectus Supplement will specify the Interest Rate for each series or
class of Fixed-Income Securities, or the initial Interest Rate and the method
for determining subsequent changes to the Interest Rate.
 
     A series may include one or more classes of Fixed-Income Securities ('Strip
Securities') entitled to (i) principal distributions, with disproportionate,
nominal or no interest distributions, or (ii) interest distributions, with
disproportionate, nominal or no principal distributions. In addition, a series
may include two or more classes of Fixed-Income Securities that differ as to
timing, sequential order, priority of payment, Interest Rate or amount of
distributions of principal or interest or both, or as to which distributions of
principal or interest or both on any class may be made upon the occurrence of
specified events, in accordance with a schedule or formula, or on the basis of
collections from designated portions of the related Mortgage Pool, which series
may include one or more classes of Fixed-Income Securities ('Accrual
Securities'), as to which certain accrued interest will not be distributed but
rather will be added to the principal balance (or nominal principal balance in
the case of Accrual Securities which are also Strip Securities) thereof on each
Payment Date, as hereinafter defined and in the manner described in the related
Prospectus Supplement.
 
     If so provided in the related Prospectus Supplement, a series of Securities
may include one or more classes of Fixed-Income Securities (collectively, the
'Senior Securities') that are senior to one or more classes of Fixed-Income
Securities (collectively, the 'Subordinate Securities') in respect of certain
distributions of principal and interest and allocations of losses on Mortgage
Loans. In addition, certain classes of Senior (or Subordinate) Securities may be
senior to other classes of Senior (or Subordinate) Securities in respect of such
distributions or losses.
 
     Equity Securities will represent the right to receive the proceeds of the

related Trust Estate after all required payments have been made to the
Securityholders of the related Fixed-Income Securities (both Senior Securities
and Subordinate Securities), and following any required deposits to any reserve
account that may be established for the benefit of the Fixed-Income Securities.
Equity Securities may constitute what are commonly referred to as the 'residual
interest,' 'seller's interest' or the 'general partnership interest,' depending
upon the treatment of the related Trust for federal income tax purposes. As
distinguished from the Fixed-Income Securities, the Equity Securities will not
be styled as having principal and interest components. Any losses suffered by
the related Trust first will be absorbed by the related class of Equity
Securities, as described herein and in the related Prospectus Supplement.
 
     No Class of Equity Securities will be offered pursuant to this Prospectus
or any Prospectus Supplement related hereto. Equity Securities may be offered on
a private placement basis or pursuant to a separate Registration Statement to be
filed by the Sponsor. In addition, the Sponsor and its affiliates may initially
or permanently hold any Equity Securities issued by any Trust.
 
     General Payment Terms of Securities.  As provided in the related Pooling
and Servicing Agreement and as described in the related Prospectus Supplement,
Securityholders will be entitled to receive payments on their
 
                                       35
<PAGE>
Securities on specified dates ('Payment Dates'). Payment Dates with respect to
Fixed-Income Securities will occur monthly, quarterly or semi-annually, as
described in the related Prospectus Supplement; Payment Dates with respect to
Equity Securities will occur as described in the related Prospectus Supplement.
 
     The related Prospectus Supplement will describe a date (the 'Record Date')
preceding such Payment Date, as of which the Trustee or its paying agent will
fix the identity of the Securityholders for the purpose of receiving payments on
the next succeeding Payment Date. Unless otherwise described in the related
Prospectus Supplement, the Payment Date will be the twenty-fifth day of each
month (or, in the case of quarterly-pay Securities, the twenty-fifth day of
every third month; and, in the case of semi-annually-pay Securities, the twenty-
fifth day of every sixth month) and the Record Date will be the close of
business as of the last day of the calendar month which precedes such Payment
Date.
 
     The related Prospectus Supplement and the Pooling and Servicing Agreement
will describe a period (a 'Remittance Period') antecedent to each Payment Date
(for example, in the case of monthly-pay Securities, the calendar month
preceding the month in which a Payment Date occurs or such other specified
period). Unless otherwise provided in the related Prospectus Supplement,
collections received on or with respect to the related Mortgage Loans during a
Remittance Period will be required to be remitted by the Master Servicer to the
related Trustee prior to the related Payment Date and will be used to distribute
payments to Securityholders on such Payment Date. As may be described in the
related Prospectus Supplement, the related Pooling and Servicing Agreement may
provide that all or a portion of the principal collected on or with respect to
the related Mortgage Loans may be applied by the related Trustee to the
acquisition of additional Mortgage Loans during a specified period (rather than
used to distribute payments of principal to Securityholders during such period)

with the result that the related securities possess an interest-only period,
also commonly referred to as a revolving period, which will be followed by an
amortization period. Any such interest-only or revolving period may, upon the
occurrence of certain events to be described in the related Prospectus
Supplement, terminate prior to the end of the specified period and result in the
earlier than expected amortization of the related Securities.
 
     In addition, and as may be described in the related Prospectus Supplement,
the related Pooling and Servicing Agreement may provide that all or a portion of
such collected principal may be retained by the Trustee (and held in certain
temporary investments, including Mortgage Loans) for a specified period prior to
being used to distribute payments of principal to Securityholders.
 
     The result of such retention and temporary investment by the Trustee of
such principal would be to slow the amortization rate of the related Securities
relative to the amortization rate of the related Mortgage Loans, or to attempt
to match the amortization rate of the related Securities to an amortization
schedule established at the time such Securities are issued. Any such feature
applicable to any Securities may terminate upon the occurrence of events to be
described in the related Prospectus Supplement, resulting in the current funding
of principal payments to the related Securityholders and an acceleration of the
amortization of such Securities.
 
     Unless otherwise specified in the related Prospectus Supplement, neither
the Securities nor the underlying Mortgage Loans will be guaranteed or insured
by any governmental agency or instrumentality or the Sponsor, the Master
Servicer, any Sub-Servicer, any Originator or any of their affiliates.
 
     Unless otherwise specified in the Prospectus Supplement with respect to a
series, Securities of each series covered by a particular Pooling and Servicing
Agreement will evidence specified beneficial ownership interest in a separate
Trust Estate created pursuant to such Pooling and Servicing Agreement. A Trust
Estate will consist of, to the extent provided in the Pooling and Servicing
Agreement: (i) a pool of Mortgage Loans (and the related mortgage documents) or
certificates of interest or participations therein underlying a particular
series of Securities as from time to time are subject to the Pooling and
Servicing Agreement, exclusive of, if specified in the related Prospectus
Supplement, any Originator's Retained Yield or other interest retained by the
related Originator, the Sponsor or any of its affiliates with respect to each
such Mortgage Loan; (ii) certain other assets including, without limitation,
payments and collections in respect of the Mortgage Loans due, accrued or
received, as described in the related Prospectus Supplement, on and after the
related Cut-Off Date, as from time to time are identified as deposited in
respect thereof in the Principal and Interest Account and in the related
Distribution Account; (iii) property acquired by foreclosure of the Mortgage
Loans or deed in lieu of foreclosure; (iv) hazard insurance policies and primary
insurance policies, if any, and certain proceeds thereof; and (v) any
combination, as specified in the related Prospectus Supplement, of a letter of
credit, financial guaranty insurance
 
                                       36
<PAGE>
policy, purchase obligation, mortgage pool insurance policy, special hazard
insurance policy, bankruptcy bond, reserve fund or other type of Credit

Enhancement as described under 'Description of Credit Enhancement.' To the
extent that any Trust Estate includes certificates of interest or participations
in Mortgage Loans, the related Prospectus Supplement will describe the material
terms and conditions of such certificates or participations.
 
FORM OF SECURITIES
 
     Unless otherwise specified in the related Prospectus Supplement, the
Securities of each series will be issued as physical certificates ('Physical
Certificates') in fully registered form only in the denominations specified in
the related Prospectus Supplement, and will be transferable and exchangeable at
the corporate trust office of the registrar of the Securities (the 'Security
Registrar') named in the related Prospectus Supplement. No service charge will
be made for any registration of exchange or transfer of Securities, but the
Trustee may require payment of a sum sufficient to cover any tax or other
governmental charge.
 
     If so specified in the related Prospectus Supplement, specified classes of
a series of Securities will be issued in uncertificated book-entry form
('Book-Entry Securities'), and will be registered in the name of Cede, the
nominee of DTC. DTC is a limited purpose trust company organized under the laws
of the State of New York, a member of the Federal Reserve System, a 'clearing
corporation' within the meaning of the Uniform Commercial Code ('UCC') and a
'clearing agency' registered pursuant to the provisions of Section 17A of the
Securities Exchange Act of 1934, as amended. DTC was created to hold securities
for its participating organizations ('Participants') and facilitate the
clearance and settlement of securities transactions between Participants through
electronic book-entry changes in their accounts, thereby eliminating the need
for physical movement of certificates. Participants include securities brokers
and dealers, banks, trust companies and clearing corporations and may include
certain other organizations. Indirect access to the DTC system also is available
to others such as brokers, dealers, banks and trust companies that clear through
or maintain a custodial relationship with a Participant, either directly or
indirectly ('Indirect Participant').
 
     Under a book-entry format, Securityholders that are not Participants or
Indirect Participants but desire to purchase, sell or otherwise transfer
ownership of Securities registered in the name of Cede, as nominee of DTC, may
do so only through Participants and Indirect Participants. In addition, such
Securityholders will receive all distributions of principal of and interest on
the Securities from the Trustee through DTC and its Participants. Under a
book-entry format, Securityholders will receive payments after the related
Payment Date because, while payments are required to be forwarded to Cede, as
nominee for DTC, on each such date, DTC will forward such payments to its
Participants, which thereafter will be required to forward such payments to
Indirect Participants or Securityholders. Unless and until Physical Securities
are issued, it is anticipated that the only Securityholder will be Cede, as
nominee of DTC, and that the beneficial holders of Securities will not be
recognized by the Trustee as Securityholders under the Pooling and Servicing
Agreement. The beneficial holders of such Securities will only be permitted to
exercise the rights of Securityholders under the Pooling and Servicing Agreement
indirectly through DTC and its Participants who in turn will exercise their
rights through DTC.
 

     Under the rules, regulations and procedures creating and affecting DTC and
its operations, DTC is required to make book-entry transfers among Participants
on whose behalf it acts with respect to the Securities and is required to
receive and transmit payments of principal of and interest on the Securities.
Participants and Indirect Participants with which Securityholders have accounts
with respect to their Securities similarly are required to make book-entry
transfers and receive and transmit such payments on behalf of their respective
Securityholders. Accordingly, although Securityholders will not possess
Securities, the rules provide a mechanism by which Securityholders will receive
distributions and will be able to transfer their interests.
 
     Unless and until Physical Certificates are issued, Securityholders who are
not Participants may transfer ownership of Securities only through Participants
by instructing such Participants to transfer Securities, by book-entry transfer,
through DTC for the account of the purchasers of such Securities, which account
is maintained with their respective Participants. Under the Rules and in
accordance with DTC's normal procedures, transfers of ownership of Securities
will be executed through DTC and the accounts of the respective Participants at
DTC will be debited and credited. Similarly, the respective Participants will
make debits or credits, as the case may be, on their records on behalf of the
selling and purchasing Securityholders.
 
                                       37
<PAGE>
     Because DTC can only act on behalf of Participants, who in turn act on
behalf of Indirect Participants and certain banks, the ability of a
Securityholder to pledge Securities to persons or entities that do not
participate in the DTC system, or otherwise take actions in respect of such
Securities may be limited due to the lack of a Physical Certificate for such
Securities.
 
     DTC in general advises that it will take any action permitted to be taken
by a Securityholder under a Pooling and Servicing Agreement only at the
direction of one or more Participants to whose account with DTC the related
Securities are credited. Additionally, DTC in general advises that it will take
such actions with respect to specified percentages of the Securityholders only
at the direction of and on behalf of Participants whose holdings include current
principal amounts of outstanding Securities that satisfy such specified
percentages. DTC may take conflicting actions with respect to other current
principal amounts of outstanding Securities to the extent that such actions are
taken on behalf of Participants whose holdings include such current principal
amounts of outstanding Securities.
 
     Any Securities initially registered in the name of Cede, as nominee of DTC,
will be issued in fully registered, certificated form to Securityholders or
their nominees ('Physical Certificates'), rather than to DTC or its nominee only
under the events specified in the related Pooling and Servicing Agreement and
described in the related Prospectus Supplement. Upon the occurrence of any of
the events specified in the related Pooling and Servicing Agreement and the
Prospectus Supplement, DTC will be required to notify all Participants of the
availability through DTC of Physical Certificates. Upon surrender by DTC of the
securities representing the Securities and instruction for reregistration, the
Trustee will issue the Securities in the form of Physical Certificates, and
thereafter the Trustee will recognize the holders of such Physical Certificates

as Securityholders. Thereafter, payments of principal of and interest on the
Securities will be made by the Trustee directly to Securityholders in accordance
with the procedures set forth herein and in the Pooling and Servicing Agreement.
The final distribution of any Security (whether Physical Certificates or
Securities registered in the name of Cede), however, will be made only upon
presentation and surrender of such Securities on the final Payment Date at such
office or agency as is specified in the notice of final payment to
Securityholders.
 
     None of the Company, the Originators, the Master Servicer or the Trustee
will have any liability for any actions taken by DTC or its nominee or Cedel or
Euroclear, including, without limitation, actions for any aspect of the records
relating to or payments made on account of beneficial ownership interests in the
Securities held by Cede, as nominee for DTC, or for maintaining, supervising or
reviewing any records relating to such beneficial ownership interests.
 
ASSIGNMENT OF MORTGAGE LOANS
 
     At the time of issuance of a series of Securities, the Sponsor will cause
the Mortgage Loans being included in the related Trust Estate to be assigned to
the Trustee together with, unless otherwise specified in the related Prospectus
Supplement, all payments and collections in respect of the Mortgage Loans due,
accrued or received, as described in the related Prospectus Supplement on or
after the related Cut-Off Date. If specified in the related Prospectus
Supplement, the Sponsor or any of its affiliates may retain the Originator's
Retained Yield, if any, for itself or transfer the same to others. The Trustee
will, concurrently with such assignment, deliver a series of Securities to the
Sponsor in exchange for the Mortgage Loans. Each Mortgage Loan will be
identified in a schedule appearing as an exhibit to the related Pooling and
Servicing Agreement. Such schedule will include, among other things, information
as to the principal balance of each Mortgage Loan as of the Cut-Off Date, as
well as information regarding the Mortgage Rate, the currently scheduled monthly
payment of principal and interest and the maturity of the Mortgage Note.
 
     In connection with the establishment of certain Trusts the Sponsor may
first transfer the related Trust Estate to the Transferor and the Transferor
will then transfer such Trust Estate to the related Trust. The use of the
Transferor will not affect the obligations of the Sponsor with respect to the
related Trust or the related Securities. If the Transferor is to be involved in
a particular offering the related Prospectus Supplement will describe its role
in such offering; for purposes of this Prospectus the role of the Transferor is
subsumed in the role of the Sponsor.
 
     The related Prospectus Supplement will describe any applicable requirements
relating to the delivery of documents, such as the related Notes, and the
preparation and/or filing of transfer documentation, such as assignments of
Mortgage, in connection with the establishment of the related Trust. To the
extent that the ratings,
 
                                       38
<PAGE>
if any, then assigned to the unsecured debt of the Sponsor or of the Sponsor's
ultimate corporate parent are satisfactory to the Rating Agencies, all or any
portion of such document delivery requirements and/or transfer document

preparation and filing requirements may be waived, all as to be described in the
related Prospectus Supplement.
 
     A typical provision relating to document delivery requirements would
provide that the Sponsor deliver to the Trustee a file consisting of (i) the
original Notes or certified copies thereof, endorsed by the Originator thereof
in blank or to the order of the holder, (ii) originals of all intervening
assignments, showing a complete chain of title from origination to the
applicable Originators, if any, including warehousing assignments, with evidence
of recording thereon, (iii) originals of all assumption and modification
agreements, if any, and, unless such Mortgage Loan is covered by a counsel's
opinion as described in the next paragraph, (iv) either: (a) the original
Mortgage, with evidence of recording thereon, (b) a true and accurate copy of
the Mortgage where the original has been transmitted for recording, until such
time as the original is returned by the public recording office or (c) a copy of
the Mortgage certified by the public recording office in those instances where
the original recorded Mortgage has been lost. To the extent that such a file
containing all or a portion of such items has been delivered to the Trustee, the
Trustee will generally be required, for the benefit of the Securityholders, to
review each such file within a specified period, generally not exceeding 90
days, to ascertain that all required documents (or certified copies of
documents) have been executed and received.
 
     A typical provision relating to the preparation and filing of transfer
documentation would require the Originators to cause to be prepared and
recorded, within a specified period, generally not exceeding 75 business days of
the execution and delivery of the applicable Pooling and Servicing Agreement
(or, if original recording information is unavailable, within such later period
as is permitted by the Pooling and Servicing Agreement) assignments of the
Mortgages from the Originators to the Trustee, in the appropriate jurisdictions
in which such recordation is necessary to perfect the lien thereof as against
creditors of or purchasers from the Originators, to the Trustee; provided,
however, that if the Originators furnish to the Trustee and to the Certificate
Insurer an opinion of counsel to the effect that no such recording is necessary
to perfect the Trustee's interests in the Mortgages with respect to any of the
jurisdictions in which the related Mortgaged Properties are located, then such
recording will not be required with respect to such jurisdictions or at the
election of the Certificate Insurer, any jurisdiction.
 
     Unless otherwise specified in the related Prospectus Supplement, if any
such document is found to be missing or defective in any material respect, the
Trustee (or such custodian) shall promptly so notify the Sponsor, which shall
notify the related Sub-Servicer or Originator, as the case may be. If the
Sub-Servicer or Originator does not cure the omission or defect within a
specified period, generally not exceeding 60 days after notice is given to the
Sponsor, the Sub-Servicer or Originator, as the case may be, will be obligated
to purchase on the next succeeding Remittance Date the related Mortgage Loan
from the Trustee at its Loan Purchase Price (or, if specified in the related
Prospectus Supplement, will be permitted to substitute for such Mortgage Loan
under the conditions specified in the related Prospectus Supplement). The Master
Servicer will be obligated to enforce this obligation of the Sub-Servicer or
Originator, as the case may be, to the extent described above under 'Mortgage
Loan Program--Representations by Originators.' Unless otherwise specified in the
related Prospectus Supplement, neither the Master Servicer nor the Sponsor will,

however, be obligated to purchase or substitute for such Mortgage Loan if the
Sub-Servicer or Originator, as the case may be, defaults on its obligation to do
so, and there can be no assurance that a Sub-Servicer or Originator, as the case
may be, will carry out any such obligation. Unless otherwise specified in the
related Prospectus Supplement, such purchase obligation constitutes the sole
remedy available to the Securityholders or the Trustee for omission of, or a
material defect in, a constituent document.
 
     The Trustee will be authorized at any time to appoint a custodian pursuant
to a custodial agreement to maintain possession of and, if applicable, to review
the documents relating to the Mortgage Loans as the agent of the Trustee. The
identity of any such custodian to be appointed on the date of initial issuance
of the Securities will be set forth in the related Prospectus Supplement.
 
     Pursuant to each Pooling and Servicing Agreement, the Master Servicer,
either directly or through Sub-Servicers, will service and administer the
Mortgage Loans assigned to the Trustee as more fully set forth below.

FORWARD COMMITMENTS; PRE-FUNDING
 
     A Trust may enter into an agreement (each, a 'Forward Purchase Agreement')
with the Sponsor whereby the Sponsor will agree to transfer additional Mortgage
Loans to such Trust following the date on which such Trust is established and
the related Securities are issued. The Trust may enter into Forward Purchase
Agreements to permit the acquisition of additional Mortgage Loans (the
'Subsequent Mortgage Loans') that could not be delivered by the Sponsor or have
not formally completed the origination process, in each case prior to the date
on which the Securities are delivered to the Securityholders (the 'Closing
Date'). Any Forward Purchase Agreement will require that any Mortgage Loans so
transferred to a Trust conform to the requirements specified in such Forward
Purchase Agreement. In addition, the Forward Purchase Agreement states that the
Depositor shall only transfer the Subsequent Mortgage Loans upon the
satisfaction of certain conditions including that the Depositor shall have
delivered to the Certificate Insurer, the Rating Agencies and the Trustee
opinions of counsel (including bankruptcy, corporate and tax opinions) with
respect to the transfer of the Subsequent Mortgage Loans.
 
     If a Forward Purchase Agreement is to be utilized, and unless otherwise
specified in the related Prospectus Supplement, the related Trustee will be
required to deposit in a segregated account (each, a 'Pre-Funding Account') up
to 100% of the net proceeds received by the Trustee in connection with the sale
of one or more classes of Securities of the related series; the additional
Mortgage Loans will be transferred to the related Trust in exchange for money
released to the Sponsor from the related Pre-Funding Account. Each Forward
Purchase Agreement will set a specified period (the 'Funding Period') during
which any such transfers must occur; for a Trust which elects federal income
treatment as a REMIC or as a grantor trust, the related Funding Period will be
limited to three months from the date such Trust is established; for a Trust
which is treated as a mere security device for federal income tax purposes, the
related Funding Period will be limited to nine months from the date such Trust
is established. The Forward Purchase Agreement or the related Pooling and
Servicing Agreement will require that, if all moneys originally deposited to

such Pre-Funding Account are not so used by the end of the related Funding
Period, then any remaining moneys will be applied as a mandatory prepayment of
the related class or classes of Securities as specified in the related
Prospectus Supplement.
 
     During the Funding Period, the moneys deposited to the Pre-Funding Account
will either (i) be held uninvested or (ii) will be invested in cash-equivalent
investments that are rated in one of the four highest rating categories by at
least one nationally recognized statistical rating organization and that will
either mature prior to the end of the Funding Period, or will be drawable on
demand and in any event, will not constitute the type of investment that would
require registration of the related Trust as an 'investment company' under the
Investment Company Act of 1940, as amended. On payment dates that occur during
the Funding Period, the Trustee will transfer any earnings on the moneys in the
Pre-Funding Account to the Certificate Account for distribution to the
Certificateholders.
 
     The Pre-Funding Account will be maintained by the Trustee, which must be a
bank having combined capital and surplus, generally, of a least $100,000,000,
long-term, unsecured debt rated at least investment grade and a long-term
deposit rating of at least investment grade.
 
PAYMENTS ON MORTGAGE LOANS; DEPOSITS TO DISTRIBUTION ACCOUNT
 
     Each Sub-Servicer servicing a Mortgage Loan pursuant to a Sub-Servicing
Agreement will establish and maintain an account (the 'Sub-Servicing Account')
which generally meets the requirements set forth in the Sponsor's Originator
Guide from time to time, and is otherwise acceptable to the Master Servicer. A
Sub-Servicing Account must be established with a Federal Home Loan Bank or with
a depository institution (including the Sub-Servicer itself) whose accounts are
insured by the National Credit Union Share Insurance Fund or the FDIC, provided
that any such depository institution must meet certain minimum rating criteria
set forth in the Sponsor's Originator Guide. Except as otherwise permitted by
the applicable Rating Agencies, a Sub-Servicing Account must be segregated and
may not be established as a general ledger account.
 
     A Sub-Servicer is required to deposit into its Sub-Servicing Account on a
daily basis all amounts described above under 'Mortgage Loan
Program--Sub-Servicing by Originators' that are received by it in respect of the
Mortgage Loans, less its servicing or other compensation. On or before the date
specified in the Sub-Servicing Agreement (which date may be no later than the
business day prior to the Determination Date referred to below
 
                                       40
<PAGE>
or, if such day is not a business day, the preceding business day), the
Sub-Servicer must remit or cause to be remitted to the Master Servicer all funds
held in the Sub-Servicing Account with respect to Mortgage Loans that are
required to be so remitted. A Sub-Servicer may also be required to make such
Servicing Advances and Delinquency Advances and to pay Compensating Interest as
set forth in the related Sub-Servicing Agreement.
 
     The Master Servicer will deposit or will cause to be deposited into the
Principal and Interest Account on a daily basis certain payments and collections

due, accrued or received, as described in the related Prospectus Supplement on
or after to the Cut-Off Date, as specifically set forth in the related Pooling
and Servicing Agreement, such as the following except as otherwise provided
therein:
 
          (i) all payments on account of principal, including principal payments
     received in advance of the date on which the related monthly payment is due
     (the 'Due Date') ('Principal Prepayments'), on the Mortgage Loans
     comprising a Trust Estate;
 
          (ii) all payments on account of interest on the Mortgage Loans
     comprising such Trust Estate, net of the portion of each payment thereof
     retained by the Sub-Servicer, if any, as its servicing or other
     compensation;
 
          (iii) all amounts received and retained, if any, in connection with
     the liquidation of any defaulted Mortgage Loan, by foreclosure, deed in
     lieu of foreclosure or otherwise ('Liquidation Proceeds'), including all
     proceeds of any special hazard insurance policy, bankruptcy bond, mortgage
     pool insurance policy, financial guaranty insurance policy and any title,
     hazard or other insurance policy covering any Mortgage Loan in such
     Mortgage Pool (together with any payments under any letter of credit,
     'Insurance Proceeds') or proceeds from any alternative arrangements
     established in lieu of any such insurance and described in the applicable
     Prospectus Supplement, other than proceeds to be applied to the restoration
     of the related property or released to the Mortgagor in accordance with the
     Master Servicer's normal servicing procedures (such amounts, net of related
     unreimbursed liquidation expenses and insured expenses incurred and
     unreimbursed advances of the Master Servicer or by the related
     Sub-Servicer, 'Net Liquidation Proceeds');
 
          (iv) any Buydown Funds (and, if applicable, investment earnings
     thereon) required to be paid to Securityholders, as described below;
 
          (v) all proceeds of any Mortgage Loan in such Trust Estate purchased
     (or, in the case of a substitution, certain amounts representing a
     principal adjustment) by the Master Servicer, the Sponsor, any Sub-Servicer
     or Originator or any other person pursuant to the terms of the Pooling and
     Servicing Agreement. See 'Mortgage Loan Program--Representations by
     Originators,' '--Assignment of Mortgage Loans' above;
 
          (vi) any amounts required to be deposited by the Master Servicer in
     connection with losses realized on investments of funds held in the
     Principal and Interest Account, as described below;
 
          (vii) any amounts required to be deposited in connection with the
     liquidation of the related Trust; and
 
          (viii) any amounts required to be transferred from the Distribution
     Account to the Principal and Interest Account.
 
     In addition to the Principal and Interest Account, the Sponsor shall cause
to be established and the Trustee will maintain, at the corporate trust office
of the Trustee, in the name of the Trust for the benefit of the holders of each

series of Securities, an account for the disbursement of payments on the
Mortgage Loans evidenced by each series of Securities (the 'Distribution
Account'). The Principal and Interest Account and the Distribution Account each
must be maintained with a Designated Depository Institution. A 'Designated
Depository Institution' is an institution whose deposits are insured by the Bank
Insurance Fund or the Savings Association Insurance Fund of the FDIC, the
long-term deposits of which have a rating satisfactory to the Rating Agencies
and the related Credit Enhancer, if any, and which is any of the following: (i)
a federal savings and loan association duly organized, validly existing and in
good standing under the federal banking laws, (ii) an institution duly
organized, validly existing and in good standing under the applicable banking
laws of any state, (iii) a national banking association duly organized, validly
existing and in good standing under the federal banking laws, (iv) a principal
subsidiary of a bank holding company, or (v) approved in writing by the related
Credit Enhancer, if any, each Rating Agency and, in each case acting or
designated by the Master Servicer as the depository institution for the
Principal and Interest Account; provided, however, that any such institution or
 
                                       41
<PAGE>
association will generally be required to have combined capital, surplus and
undivided profits of at least $50,000,000. Notwithstanding the foregoing, the
Principal and Interest Account may be held by an institution otherwise meeting
the preceding requirements except that the only applicable rating requirement
shall be that the unsecured and uncollateralized debt obligations thereof shall
be rated at a level satisfactory to one or more Rating Agencies if such
institution has trust powers and the Principal and Interest Account is held by
such institution in its trust capacity and not in its commercial capacity. The
Distribution Account, the Principal and Interest Account and other accounts
described in the related Prospectus Supplement are collectively referred to as
'Accounts.' All funds in the Distribution Account shall be invested and
reinvested by the Trustee for the benefit of the Securityholders and the related
Credit Enhancer, if any, as directed by the Master Servicer, in certain defined
obligations set forth in the related Pooling and Servicing Agreement ('Eligible
Investments'). The Principal and Interest Account may contain funds relating to
more than one series of Securities as well as payments received on other
mortgage loans serviced or master serviced by it that have been deposited into
the Principal and Interest Account. All funds in the Principal and Interest
Account will be required to be held (i) uninvested, up to limits insured by the
FDIC or (ii) invested in Eligible Investments. The Master Servicer will be
entitled to any interest or other income or gain realized with respect to the
funds on deposit in the Principal and Interest Account.
 
     To the extent that the ratings, if any, then assigned to the unsecured debt
of the Master Servicer or of the Master Servicer's corporate parent and
satisfactory to the Rating Agencies, the Master Servicer may be permitted to
co-mingle Mortgage Loan payments and collections with the Master Servicer's
general funds rather than required to deposit such amounts into a segregated
Principal and Interest Account.
 
     Unless otherwise specified in the related Prospectus Supplement, on the day
seven days preceding each Payment Date (the 'Remittance Date'), the Master
Servicer will withdraw from the Principal and Interest Account and remit to the
Trustee for deposit in the applicable Distribution Account, in immediately

available funds, the amount to be distributed therefrom to Securityholders on
such Payment Date. The Master Servicer will remit to the Trustee for deposit
into the Distribution Account the amount of any advances made by the Master
Servicer as described herein under '--Advances,' any amounts required to be
transferred to the Distribution Account from a Reserve Fund, as described under
'Credit Enhancement' below, any amounts required to be paid by the Master
Servicer out of its own funds due to the operation of a deductible clause in any
blanket policy maintained by the Master Servicer to cover hazard losses on the
Mortgage Loans as described under 'Hazard Insurance; Claims Thereunder--Hazard
Insurance Policies' below and any other amounts as specifically set forth in the
related Pooling and Servicing Agreement. The Trustee will cause all payments
received by it from any Credit Enhancer to be deposited in the Distribution
Account not later than the related Payment Date.
 
     Unless otherwise specified in the related Prospectus Supplement, the
portion of any payment received by the Master Servicer in respect of a Mortgage
Loan that is allocable to the Originator's Retained Yield generally will not be
deposited into the Principal and Interest Account, but will not be paid over to
the parties entitled thereto as provided in the related Pooling and Servicing
Agreement.
 
     Funds on deposit in the Principal and Interest Account attributable to
Mortgage Loans underlying a series of Securities may be invested in Eligible
Investments maturing in general not later than the business day preceding the
next Payment Date. Unless otherwise specified in the related Prospectus
Supplement, all income and gain realized from any such investment will be for
the account of the Master Servicer. Funds on deposit in the related Distribution
Account may be invested in Eligible Investments maturing, in general, no later
than the business day preceding the next Payment Date.
 
     With respect to each Buydown Mortgage Loan, the Sub-Servicer will deposit
the related Buydown Funds provided to it in a Buydown Account that will comply
with the requirements set forth herein with respect to a Sub-Servicing Account.
Unless otherwise specified in the related Prospectus Supplement, the terms of
all Buydown Mortgage Loans provide for the contribution of Buydown Funds in an
amount equal to or exceeding either (i) the total payments to be made from such
funds pursuant to the related buydown plan or (ii) if such Buydown Funds are to
be deposited on a discounted basis, that amount of Buydown Funds which, together
with investment earnings thereon at a rate as set forth in the Sponsor's
Originator Guide from time to time, will support the scheduled level of payments
due under the Buydown Mortgage Loan. Neither the Master Servicer nor the Sponsor
will be obligated to add to any such discounted Buydown Funds any of its own
funds should investment earnings prove insufficient to maintain the scheduled
level of payments. To the extent that any such
 
                                       42
<PAGE>
insufficiency is not recoverable from the Mortgagor or, in an appropriate case,
from the related Originator or the related Sub-Servicer, distributions to
Securityholders may be affected. With respect to each Buydown Mortgage Loan, the
Sub-Servicer will withdraw from the Buydown Account and remit to the Master
Servicer on or before the date specified in the Sub-Servicing Agreement
described above the amount, if any, of the Buydown Funds (and, if applicable,
investment earnings thereon) for each Buydown Mortgage Loan that, when added to

the amount due from the Mortgagor on such Buydown Mortgage Loan, equals the full
monthly payment which would be due on the Buydown Mortgage Loan if it were not
subject to the buydown plan.
 
     If the Mortgagor on a Buydown Mortgage Loan prepays such Mortgage Loan in
its entirety during the Buydown Period, the Sub-Servicer will withdraw from the
Buydown Account and remit to the Mortgagor or such other designated party in
accordance with the related buydown plan any Buydown Funds remaining in the
Buydown Account. If a prepayment by a Mortgagor during the Buydown Period
together with Buydown Funds will result in full prepayment of a Buydown Mortgage
Loan, the Sub-Servicer will generally be required to withdraw from the Buydown
Account and remit to the Master Servicer the Buydown Funds and investment
earnings thereon, if any, which together with such prepayment will result in a
prepayment in full; provided that Buydown Funds may not be available to cover a
prepayment under certain Mortgage Loan programs. Any Buydown Funds so remitted
to the Master Servicer in connection with a prepayment described in the
preceding sentence will be deemed to reduce the amount that would be required to
be paid by the Mortgagor to repay fully the related Mortgage Loan if the
Mortgage Loan were not subject to the buydown plan. Any investment earnings
remaining in the Buydown Account after prepayment or after termination of the
Buydown Period will be remitted to the related Mortgagor or such other
designated party pursuant to the agreement relating to each Buydown Mortgage
Loan (the 'Buydown Agreement'). If the Mortgagor defaults during the Buydown
Period with respect to a Buydown Mortgage Loan and the property securing such
Buydown Mortgage Loan is sold in liquidation (either by the Master Servicer, the
Primary Insurer, the insurer under the mortgage pool insurance policy (the 'Pool
Insurer') or any other insurer), the Sub-Servicer will be required to withdraw
from the Buydown Account the Buydown Funds and all investment earnings thereon,
if any, and remit the same to the Master Servicer or, if instructed by the
Master Servicer, pay the same to the primary insurer or the Pool Insurer, as the
case may be, if the Mortgaged Property is transferred to such insurer and such
insurer pays all of the loss incurred in respect of such default.
 
WITHDRAWALS FROM THE PRINCIPAL AND INTEREST ACCOUNT
 
     The Master Servicer may, from time to time, make withdrawals from the
Principal and Interest Account for certain purposes, as specifically set forth
in the related Pooling and Servicing Agreement, which generally will include the
following except as otherwise provided therein:
 
          (i) to effect the timely remittance to the Trustee for deposit to the
     Distribution Account in the amounts and in the manner provided in the
     Pooling and Servicing Agreement and described in '--Payments on Mortgage
     Loans; Deposits to Distribution Account' above;
 
          (ii) to reimburse itself or any Sub-Servicer for any accrued and
     unpaid Servicing Fees and for Delinquency Advances and Servicing Advances
     as to any Mortgaged Property, out of late payments or 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
     related Mortgagor or otherwise relating to the Mortgage Loan with respect
     to which such Delinquency Advances or Servicing Advances were made;
 
          (iii) to reimburse itself for any Delinquency Advances or Servicing

     Advances determined in good faith to have become Non-Recoverable Advances,
     such reimbursement to be made from any funds in the Principal and Interest
     Account;
 
          (iv) to withdraw investment earnings on amounts on deposit in the
     Principal and Interest Account;
 
          (v) to pay the Sponsor or its assignee all amounts allocable to the
     Originator's Retained Yield out of collections or payments which represent
     interest on each Mortgage Loan (including any Mortgage Loan as to which
     title to the underlying Mortgaged Property was acquired);
 
          (vi) to withdraw amounts that have been deposited in the Principal and
     Interest Account in error;
 
                                       43
<PAGE>
          (vii) to clear and terminate the Principal and Interest Account in
     connection with the termination of the Trust Estate pursuant to the Pooling
     and Servicing Agreement, as described in 'The Pooling and Servicing
     Agreement--Termination, Retirement of Securities'; and
 
          (viii) to invest in Eligible Investments.
 
DISTRIBUTIONS
 
     Beginning on the Payment Date in the month following the month (or, in the
case of quarterly-pay Securities, the third month following such month and each
third month thereafter or, in the case of semi-annually-pay Securities, the
sixth month following such month and each sixth month thereafter) in which the
Cut-Off Date occurs (or such other date as may be set forth in the related
Prospectus Supplement) for a series of Securities, distributions of principal
and interest (or, where applicable, of principal only or interest only) on each
class of Securities entitled thereto will be made either by the Trustee or a
paying agent appointed by the Trustee (the 'Paying Agent'), to the persons who
are registered as Securityholders at the close of business on the Record Date in
proportion to their respective Percentage Interests. Unless otherwise specified
in the related Prospectus Supplement, interest that accrues and is not payable
on a class of Securities will be added to the principal balance of each Security
of such class in proportion to its Percentage Interest. The undivided percentage
interest (the 'Percentage Interest') represented by a Security of a particular
class will be equal to the percentage obtained by dividing the initial principal
balance or notional amount of such Security by the aggregate initial amount or
notional balance of all the Securities of such class. Distributions will be made
in immediately available funds (by wire transfer or otherwise) to the account of
a Securityholder at a bank or other entity having appropriate facilities
therefor, if such Securityholder has so notified the Trustee or the Paying
Agent, as the case may be, and the applicable Pooling and Servicing Agreement
provides for such form of payment, or by check mailed to the address of the
person entitled thereto as it appears on the Security Register; provided,
however, that the final distribution in retirement of the Securities (other than
any Book-Entry Securities) will be made only upon presentation and surrender of
the Securities at the office or agency of the Trustee specified in the notice to
Securityholders of such final distribution.

 
PRINCIPAL AND INTEREST ON THE SECURITIES
 
     The method of determining, and the amount of, distributions of principal
and interest (or, where applicable, of principal only or interest only) on a
particular series of Securities will be described in the related Prospectus
Supplement. Each class of Securities (other than certain classes of Strip
Securities) may bear interest at a different interest rate (the 'Pass-Through
Rate'), which may be a fixed or adjustable Pass-Through Rate. The related
Prospectus Supplement will specify the Pass-Through Rate for each class, or in
the case of an adjustable Pass-Through Rate, the initial Pass-Through Rate and
the method for determining the Pass-Through Rate. Unless otherwise specified in
the related Prospectus Supplement, interest on the Securities will be calculated
on the basis of a 360-day year consisting of twelve 30-day months.
 
     On each Payment Date for a series of Securities, the Trustee will
distribute or cause the Paying Agent to distribute, as the case may be, to each
holder of record on the Record Date of a class of Securities, an amount equal to
the Percentage Interest represented by the Security held by such holder
multiplied by such class' Distribution Amount. The Distribution Amount for a
class of Securities for any Payment Date will be the portion, if any, of the
principal distribution amount (as defined in the related Prospectus Supplement)
allocable to such class for such Payment Date, as described in the related
Prospectus Supplement, plus, if such class is entitled to payments of interest
on such Payment Date, the interest accrued at the applicable Pass-Through Rate
on the principal balance or notional amount of such class, as specified in the
applicable Prospectus Supplement, less (unless otherwise specified in the
Prospectus Supplement) the amount of any Deferred Interest added to the
principal balance of the Mortgage Loans and/or the outstanding balance of one or
more classes of Securities on the related Due Date and any other interest
shortfalls allocable to Securityholders which are not covered by advances or the
applicable Credit Enhancement, in each case in such amount that is allocated to
such class on the basis set forth in the Prospectus Supplement.
 
     As may be described in the related Prospectus Supplement, the related
Pooling and Servicing Agreement may provide that all or a portion of the
principal collected on or with respect to the related Mortgage Loans may
 
                                       44
<PAGE>
be applied by the related Trustee to the acquisition of additional Mortgage
Loans during a specified period (rather than used to fund payments of principal
to Securityholders during such period) with the result that the related
securities will possess an interest-only period, also commonly referred to as a
revolving period, which will be followed by an amortization period. Any such
interest-only or revolving period may, upon the occurrence of certain events to
be described in the related Prospectus Supplement, terminate prior to the end of
the specified period and result in the earlier than expected amortization of the
related Securities.
 
     In addition, and as may be described in the related Prospectus Supplement,
the related Pooling and Servicing Agreement may provide that all or a portion of
such collected principal may be retained by the Trustee (and held in certain
temporary investments, including Mortgage Loans) for a specified period prior to

being used to fund payments of principal to Securityholders.
 
     In the case of a series of Securities that includes two or more classes of
Securities, the timing, sequential order, priority of payment or amount of
distributions in respect of principal, and any schedule or formula or other
provisions applicable to the determination thereof (including distributions
among multiple classes of Senior Securities or Subordinate Securities) of each
such class shall be as provided in the related Prospectus Supplement.
Distributions in respect of principal of any class of Securities will be made on
a pro rata basis among all of the Securities of such class.
 
     Except as otherwise provided in the related Pooling and Servicing
Agreement, on or prior to the third business day next preceding the Payment Date
(or such earlier day as shall be agreed by the related Credit Enhancer, if any,
and the Trustee) of the month of distribution (the 'Determination Date'), the
Trustee will determine the amounts of principal and interest which will be
passed through to Securityholders on the immediately succeeding Payment Date. If
the amount in the Distribution Account is insufficient to cover the amount to be
passed through to Securityholders, the Trustee will be required to notify the
related Credit Enhancer, if any, pursuant to the related Pooling and Servicing
Agreement for the purpose of funding such deficiency.
 
ADVANCES
 
     Unless otherwise specified in the related Prospectus Supplement, each
Servicer will be required, not later than each Remittance Date, to deposit into
the Principal and Interest Account an amount equal to the sum of the interest
portions (net of the Servicing Fees and the Originators' Retained Yield) due,
but not collected, with respect to delinquent Mortgage Loans directly serviced
by such Servicer during the prior Remittance Period, but only if, in its good
faith business judgment, such Servicer believes that such amount will ultimately
be recovered from the related Mortgage Loan. As may be described in the related
Prospectus Supplement, such Servicer may also be required so to advance
delinquent payments of principal. Any such amounts so advanced are 'Delinquency
Advances'. The Master Servicer will be permitted to fund its payment of
Delinquency Advances on any Remittance Date from collections on any Mortgage
Loan deposited to the Principal and Interest Account subsequent to the related
Remittance Period, and will be required to deposit into the Principal and
Interest Account with respect thereto (i) collections from the Mortgagor whose
delinquency gave rise to the shortfall which resulted in such Delinquency
Advance and (ii) Net Liquidation Proceeds recovered on account of the related
Mortgage Loan to the extent of the amount of aggregate Delinquency Advances
related thereto. A Sub-Servicer will be permitted to fund its payment of
Delinquency Advances as set forth in the related Sub-Servicing Agreement.
 
     A Mortgage Loan is 'delinquent' if any payment due thereon is not made by
the close of business on the day such payment is scheduled to be due.
 
     Unless otherwise specified in the related Prospectus Supplement, on or
prior to each Remittance Date, each Servicer will be required to deposit in the
Principal and Interest Account with respect to any full prepayment received on a
Mortgage Loan directly serviced by such Servicer during the related Remittance
Period out of its own funds without any right of reimbursement therefor, an
amount equal to the difference between (x) 30 days' interest at the Mortgage

Loan's Mortgage Rate (less the related Base Servicing Fees and the Originators'
Retained Yield, if any) on the principal balance of such Mortgage Loan as of the
first day of the related Remittance Period and (y) to the extent not previously
advanced, the interest (less the Servicing Fee and the Originators' Retained
Yield, if any) paid by the Mortgagor with respect to the Mortgage Loan during
such
 
                                       45
<PAGE>
Remittance Period (any such amount paid by such Servicer, 'Compensating
Interest'). No Servicer shall be required to pay Compensating Interest with
respect to any Remittance Period in an amount in excess of the aggregate related
Base Servicing Fees received by such Servicer with respect to all Mortgage Loans
directly serviced by such Servicer for such Remittance Period.
 
     Each Servicer will be required to pay all 'out of pocket' costs and
expenses incurred in the performance of its servicing obligations, but only to
the extent that such Servicer reasonably believes that such amounts will
increase Net Liquidation Proceeds on the related Mortgage Loan. Each such amount
so paid will constitute a 'Servicing Advance'. Such Servicer may recover
Servicing Advances to the extent permitted by the Mortgage Loans or, if not
theretofore recovered from the Mortgagor on whose behalf such Servicing Advance
was made, from Liquidation Proceeds realized upon the liquidation of the related
Mortgage Loan or, in certain cases, from excess cash flow otherwise payable to
the holders of the related Equity Securities or prior to any distributions being
made to the related Securityholders.
 
     Notwithstanding the foregoing, if the Master Servicer exercises its option,
if any, to purchase the assets of a Trust Estate as described under 'The Pooling
and Servicing Agreement--Termination; Retirement of Securities' below, the
Master Servicer will net from the purchase price of such amounts for all related
advances previously made by it and not theretofore reimbursed to it. The Master
Servicer's obligation to make advances may be supported by Credit Enhancement as
described in the related Pooling and Servicing Agreement. In the event that the
provider of such support is downgraded by a Rating Agency rating the related
Securities or if the collateral supporting such obligation is not performing or
is removed pursuant to the terms of any agreement described in the related
Prospectus Supplement, the Securities may also be downgraded.
 
REPORTS TO SECURITYHOLDERS
 
     With each distribution to Securityholders of a particular class the Trustee
will forward or cause to be forwarded to each holder of record of such class of
Securities a statement or statements with respect to the related Trust setting
forth the information specifically described in the related Pooling and
Servicing Agreement, which generally will include the following as applicable
except as otherwise provided therein:
 
          (i) the amount of the distribution with respect to each class of
     Securities;
 
          (ii) the amount of such distribution allocable to principal,
     separately identifying the aggregate amount of any prepayments or other
     recoveries of principal included therein;

 
          (iii) the amount of such distribution allocable to interest;
 
          (iv) the aggregate unpaid Principal Balance of the Mortgage Loans
     after giving effect to the distribution of principal on such Payment Date;
 
          (v) with respect to a series consisting of two or more classes, the
     outstanding principal balance or notional amount of each class after giving
     effect to the distribution of principal on such Payment Date;
 
          (vi) the amount of coverage under any letter of credit, mortgage pool
     insurance policy or other form of Credit Enhancement covering default risk
     as of the close of business on the applicable Determination Date and a
     description of any Credit Enhancement substituted therefor;
 
          (vii) information furnished by the Sponsor pursuant to section
     6049(d)(7)(C) of the Code and the regulations promulgated thereunder to
     assist Securityholders in computing their market discount;
 
          (viii) the total of any Substitution Amounts and any Loan Purchase
     Price amounts included in such distribution; and
 
          (ix) a number with respect to each class (the 'Pool Factor') computed
     by dividing the principal balance of all Securities in such class (after
     giving effect to any distribution of principal to be made on such Payment
     Date) by the original principal balance of the Securities of such class on
     the Closing Date.
 
     Items (i) through (iii) above shall, with respect to each class of
Securities, be presented on the basis of a certificate having a $1,000
denomination. In addition, by January 31 of each calendar year during which
Securities are outstanding, the Trustee shall furnish a report to each
Securityholder at any time during each
 
                                       46
<PAGE>
calendar year as to the aggregate amounts reported pursuant to (i), (ii) and
(iii) with respect to the Securities for such calendar year. If a class of
Securities are in book-entry form, DTC will supply such reports to the
Securityholders in accordance with its procedures.
 
     In addition, on each Payment Date the Trustee will forward or cause to be
forwarded additional information, as of the close of business on the last day of
the prior calendar month, as more specifically described in the related Pooling
and Servicing Agreement, which generally will include the following as
applicable except as otherwise provided therein:
 
          (i) the total number of Mortgage Loans and the aggregate principal
     balances thereof, together with the number, percentage (based on the
     then-outstanding principal balances) and aggregate principal balances of
     Mortgage Loans (a) 30-59 days delinquent, (b) 60-89 days delinquent and (c)
     90 or more days delinquent;
 
          (ii) the number, percentage (based on the then-outstanding principal

     balances), aggregate Mortgage Loan balances and status of all Mortgage
     Loans in foreclosure proceedings (and whether any such Mortgage Loans are
     also included in any of the statistics described in the foregoing clause
     (i));
 
          (iii) the number, percentage (based on the then-outstanding principal
     balances) and aggregate Mortgage Loan balances of all Mortgage Loans
     relating to Mortgagors in bankruptcy proceedings (and whether any such
     Mortgage Loans are also included in any of the statistics described in the
     foregoing clause (i));
 
          (iv) the number, percentage (based on the then-outstanding principal
     balances) and aggregate Mortgage Loan balances of all Mortgage Loans
     relating to the status of any Mortgaged Properties as to which title has
     been taken in the name of, or on behalf of the Trustee (and whether any
     such Mortgage Loans are also included in any of the statistics described in
     the foregoing clause (i)); and
 
          (v) the book value of any real estate acquired through foreclosure or
     grant of a deed in lieu of foreclosure.
 
COLLECTION AND OTHER SERVICING PROCEDURES
 
     Acting directly or through one or more Sub-Servicers as provided in the
related Pooling and Servicing Agreement, the Master Servicer, is required to
service and administer the Mortgage Loans in accordance with the Pooling and
Servicing Agreement and with reasonable care, and using that degree of skill and
attention that the Master Servicer exercises with respect to comparable mortgage
loans that it services for itself or others.
 
     The duties of the Master Servicer include collecting and posting of all
payments, responding to inquiries of Mortgagors or by federal, state or local
government authorities with respect to the Mortgage Loans, investigating
delinquencies, reporting tax information to Mortgagors in accordance with its
customary practices and accounting for collections and furnishing monthly and
annual statements to the Trustee with respect to distributions and making
Delinquency Advances and Servicing Advances to the extent described in the
related Pooling and Servicing Agreement. The Master Servicer is required to
follow its customary standards, policies and procedures in performing its duties
as Master Servicer.
 
     The Master Servicer (i) is authorized and empowered to execute and deliver,
on behalf of itself, the Securityholders and the Trustee or any of them, 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 related Mortgaged Properties; (ii) may consent to
any modification of the terms of any Note not expressly prohibited by the
Pooling and Servicing Agreement if the effect of any such modification (x) will
not materially and adversely affect the security afforded by the related
Mortgaged Property or the timing of receipt of any payments required thereunder
(in each case other than as permitted by the related Pooling and Servicing
Agreement); and (y) will not cause a Trust which is a REMIC to fail to qualify
as a REMIC.
 

     The related Pooling and Servicing Agreement will require the Master
Servicer to follow such collection procedures as it follows from time to time
with respect to mortgage loans in its servicing portfolio that are comparable to
the Mortgage Loans; provided that the Master Servicer is required always at
least to follow collection procedures that are consistent with or better than
standard industry practices. The Master Servicer may in its discretion (i) waive
any assumption fees, late payment charges, charges for checks returned for
insufficient funds, prepayment fees, if any, or the fees which may be collected
in the ordinary course of servicing the
 
                                       47
<PAGE>
Mortgage Loans, (ii) if a Mortgagor is in default or about to be in default
because of a Mortgagor's financial condition, arrange with the Mortgagor a
schedule for the payment of delinquent payments due on the related Mortgage
Loan; provided, however, the Master Servicer shall generally not be permitted to
reschedule the payment of delinquent payments more than one time in any twelve
consecutive months with respect to any Mortgagor or (iii) modify payments of
monthly principal and interest on any Mortgage Loan becoming subject to the
terms of the Relief Act in accordance with the Master Servicer's general
policies of the comparable mortgage loans subject to such Relief Act.
 
     When a Mortgaged Property (other than Mortgaged Property subject to an ARM
Loan) has been or is about to be conveyed by the Mortgagor, the Master Servicer
will be required, to the extent it has knowledge of such conveyance or
prospective conveyance, to exercise its rights to accelerate the maturity of the
related Mortgage Loan under any 'due-on-sale' clause contained in the related
Mortgage or Note; provided, however, that the Master Servicer will not be
required to exercise any such right if (i) the 'due-on-sale' clause, in the
reasonable belief of the Master Servicer, is not enforceable under applicable
law or (ii) the Master Servicer reasonably believes that to permit an assumption
of the Mortgage Loan would not materially and adversely affect the interests of
Securityholders or the related Credit Enhancer or jeopardize coverage under any
primary insurance policy or applicable Credit Enhancement arrangements. In such
event, the Master Servicer will be required to enter into an assumption and
modification agreement with the person to whom such Mortgaged Property has been
or is about to be conveyed, pursuant to which such person becomes liable under
the Mortgage Note and, unless prohibited by applicable law or the related
documents, the Mortgagor remains liable thereon. If the foregoing is not
permitted under applicable law, the Master Servicer will be authorized to enter
into a substitution of liability agreement with such person, pursuant to which
the original Mortgagor is released from liability and such person is substituted
as Mortgagor and becomes liable under the Mortgage Note. The assumed loan must
conform in all respects to the requirements, representations and warranties of
the Pooling and Servicing Agreement.
 
     An ARM Loan may be assumed if such ARM Loan is by its terms assumable and
if, in the reasonable judgment of the Master Servicer or the Sub-Servicer, the
proposed transferee of the related Mortgaged Property establishes its ability to
repay the loan and the security for such ARM Loan would not be impaired by the
assumption. If a Mortgagor transfers the Mortgaged Property subject to an ARM
Loan without consent, such ARM Loan may be declared due and payable. Any fee
collected by the Master Servicer or Sub-Servicer for entering into an assumption
or substitution of liability agreement will be retained by the Master Servicer

or Sub-Servicer as additional servicing compensation unless otherwise set forth
in the related Prospectus Supplement. See 'Certain Legal Aspects of Mortgage
Loans and Related Matters--Enforceability of Certain Provisions' herein.
 
     The Master Servicer will have the right under the Pooling and Servicing
Agreement to approve applications of Mortgagors seeking consent for (i) partial
releases of Mortgages, (ii) alterations and (iii) removal, demolition or
division of Mortgaged Properties. No application for consent may be approved by
the Master Servicer unless: (i) the provisions of the related Mortgage Note and
Mortgage have been complied with; (ii) the credit profile of the related
Mortgage Loan after any release is consistent with the Sponsor's Originator
Guide then applicable to such Mortgage Loan; and (iii) the lien priority of the
related Mortgage is not reduced.
 
REALIZATION UPON DEFAULTED MORTGAGE LOANS
 
     The Master Servicer shall foreclose upon or otherwise comparably effect the
ownership of Mortgaged Properties relating to defaulted Mortgage Loans as to
which no satisfactory arrangements can be made for collection of delinquent
payments and which the Master Servicer has not purchased pursuant to the related
Pooling and Servicing Agreement (such Mortgage Loans, 'REO Property'). In
connection with such foreclosure or other conversion, the Master Servicer shall
exercise such of the rights and powers vested in it, and use the same degree of
care and skill in their exercise or use, as prudent mortgage lenders would
exercise or use under the circumstances in the conduct of their own affairs,
including, but not limited to, making Servicing Advances for the payment of
taxes, amounts due with respect to Senior Liens, and insurance premiums. Unless
otherwise provided in the related Prospectus Supplement, the Master Servicer
shall sell any REO Property within 23 months of its acquisition by the Trust.
The Pooling and Servicing Agreements generally will permit the Master Servicer
to cease further collection and foreclosure activity if the Master Servicer
reasonably determines that such further activity would not increase collections
or recoveries to be received by the related Trust with respect to the related
Mortgage Loan. In addition, any required advancing may be permitted to cease at
this point.
 
                                       48
<PAGE>
     Notwithstanding the generality of the foregoing provisions, the Master
Servicer will be required to manage, conserve, protect and operate each REO
Property for the Securityholders solely for the purpose of its prompt
disposition and sale as 'foreclosure property' within the meaning of Section
860G(a)(8) of the Code or to prevent the receipt by the Trust of any 'income
from non-permitted assets' within the meaning of Section 860F(a)(2)(B) of the
Code or any 'net income from foreclosure property' which is subject to taxation
under the REMIC Provisions. Pursuant to its efforts to sell such REO Property,
the Master Servicer shall either itself or through an agent selected by the
Master Servicer protect and conserve such REO Property in the same manner and to
such extent as is customary in the locality where such REO Property is located
and may, incident to its conservation and protection of the interests of the
Securityholders, rent the same, or any part thereof, as the Master Servicer
deems to be in the best interest of the Securityholders for the period prior to
the sale of such REO Property. The Master Servicer shall take into account the
existence of any hazardous substances, hazardous wastes or solid wastes, as such

terms are defined in the Comprehensive Environmental Response Compensation and
Liability Act, the Resource Conservation and Recovery Act of 1976, or other
federal, state or local environmental legislation, on a Mortgaged Property in
determining whether to foreclose upon or otherwise comparably convert the
ownership of such Mortgaged Property.
 
     The Master Servicer shall determine, with respect to each defaulted
Mortgage Loan, when it has recovered, whether through trustee's sale,
foreclosure sale or otherwise, all amounts it expects to recover from or on
account of such defaulted Mortgage Loan, whereupon such Mortgage Loan shall
become a Liquidated Mortgage Loan. A Mortgage Loan which is 'charged-off', i.e.,
as to which the Master Servicer ceases further collection and/or foreclosure
activity as a result of a determination that such further actions will not
increase collections or recoveries to be received by the related Trust is also a
'Liquidated Mortgage Loan.'
 
     If a loss is realized on a defaulted Mortgage Loan or REO Property upon the
final liquidation thereof that is not covered by any applicable form of Credit
Enhancement or other insurance, the Securityholders will bear such loss.
However, if a gain results from the final liquidation of an REO Property that is
not required by law to be remitted to the related Mortgagor, the Master Servicer
will be entitled to retain such gain as additional servicing compensation unless
the related Prospectus Supplement provides otherwise. For a description of the
Master Servicer's obligations to maintain and make claims under applicable forms
of Credit Enhancement and insurance relating to the Mortgage Loans, see
'Description of Credit Enhancement' and 'Hazard Insurance; Claims Thereunder;
Hazard Insurance Policies.'

<PAGE>
                                 SUBORDINATION
 
     A Senior/Subordinate Series of Securities will consist of one or more
classes of Senior Securities and one or more classes of Subordinate Securities,
as specified in the related Prospectus Supplement. Unless otherwise specified in
the related Prospectus Supplement, only the Senior Securities will be offered
hereby. Subordination of the Subordinate Securities of any Senior/Subordinate
Series of Securities will be effected by the following method, unless an
alternative method is specified in the related Prospectus Supplement. In
addition, certain classes of Senior (or Subordinate) Securities may be senior to
other classes of Senior (or Subordinate) Securities, as specified in the related
Prospectus Supplement, in which case the following discussion is qualified in
its entirety by reference to the related Prospectus Supplement with respect to
the various priorities and other rights as among the various classes of Senior
Securities or Subordinate Securities, as the case may be.
 
     With respect to any Senior/Subordinate Series of Securities, the total
amount available for distribution on each Payment Date, as well as the method
for allocating such amount among the various classes of Securities included in
such series, will be as set forth in the related Prospectus Supplement.
Generally, the amount available for contribution will be allocated first to
interest on the Senior Securities of such series, and then to principal of the
Senior Securities up to the amounts determined as specified in the related

Prospectus Supplement, prior to allocation to the Subordinate Securities of such
series.
 
     In the event of any Realized Losses (as defined below) on Mortgage Loans
not in excess of the limitations described below, other than Extraordinary
Losses, the rights of the Subordinate Securityholders to receive distributions
with respect to the Mortgage Loans will be subordinate to the rights of the
Senior Securityholders. With respect to any defaulted Mortgage Loan that becomes
a Liquidated Mortgage Loan, through foreclosure sale, disposition of the related
Mortgaged Property if acquired by deed in lieu of foreclosure, 'charged-off' or
otherwise, the amount of loss realized, if any (as more fully described in the
related Pooling and Servicing Agreement, a 'Realized Loss'), will equal the
portion of the stated principal balance remaining, after application of all
amounts recovered (net of amounts reimbursable to the Master Servicer for
related advances and expenses) towards interest and principal owing on the
Mortgage Loan. With respect to a Mortgage Loan the principal balance of which
has been reduced in connection with bankruptcy proceedings, the amount of such
reduction will be treated as a Realized Loss.
 
     Except as noted below, all Realized Losses will be allocated to the
Subordinate Securities of the related series, until the Principal Balance (as
defined in the related Prospectus Supplement) of such Subordinate Securities
thereof has been reduced to zero. Any additional Realized Losses will be
allocated to the Senior Securities (or, if such series includes more than one
class of Senior Securities, either on a pro-rata basis among all of the Senior
Securities in proportion to their respective outstanding Principal Balances or
as otherwise provided in the related Prospectus Supplement).
 
     With respect to certain Realized Losses resulting from physical damage to
Mortgaged Properties that are generally of the same type as are covered under a
special hazard insurance policy, the amount thereof that may be allocated to the
Subordinate Securities of the related series may be limited to an amount (the
'Special Hazard Amount') specified in the related Prospectus Supplement. See
'Description of Credit Enhancement--Special Hazard Insurance Policies.' If so,
any Special Hazard Losses in excess of the Special Hazard Amount will be
allocated among all outstanding classes of Securities of the related series,
either on a pro-rata basis in proportion to their outstanding Security Principal
Balances, regardless of whether any Subordinate Securities remain outstanding,
or as otherwise provided in the related Prospectus Supplement. The respective
amounts of other specified types of losses (including Fraud Losses and
Bankruptcy Losses) that may be borne solely by the Subordinate Securities may be
similarly limited to an amount (with respect to Fraud Losses, the 'Fraud Loss
Amount' and with respect to Bankruptcy Losses, the 'Bankruptcy Loss Amount'),
and the Subordinate Securities may provide no coverage with respect to certain
other specified types of losses, as described in the related Prospectus
Supplement, in which case such losses would be allocated on a pro-rata basis
among all outstanding classes of Securities.
 
     Any allocation of a Realized Loss (including a Special Hazard Loss) to a
Security in a Senior/Subordinate Series will be made by reducing the Security
Principal Balance thereof as of the Payment Date following the calendar month in
which such Realized Loss was incurred.
 
                                       50

<PAGE>
     In lieu of the foregoing provisions, subordination may be effected in the
following manner, or in any other manner described in the related Prospectus
Supplement. The rights of the holders of Subordinate Securities to receive any
or a specified portion of distributions with respect to the Mortgage Loans may
be subordinated to the extent of the amount set forth in the related Prospectus
Supplement (the 'Subordinate Amount'). As specified in the related Prospectus
Supplement, the Subordinate Amount may be subject to reduction based upon the
amount of losses borne by the holders of the Subordinate Securities as a result
of such subordination, a specified schedule or such other method of reduction as
such Prospectus Supplement may specify. If so specified in the related
Prospectus Supplement, additional credit support for this form of subordination
may be provided by the establishment of a reserve fund for the benefit of the
holders of the Senior Securities (which may, if such Prospectus Supplement so
provides, initially be funded by a cash deposit by the Originator) into which
certain distributions otherwise allocable to the holders of the Subordinate
Securities may be placed; such funds would thereafter be available to cure
shortfalls in distributions to holders of the Senior Securities.
 
                       DESCRIPTION OF CREDIT ENHANCEMENT
 
     Unless otherwise expressly provided and described in the applicable
Prospectus Supplement, each series of Securities shall have credit support
(referred to herein as 'Credit Enhancement') comprised of one or more of the
following components. Each component will have a monetary limit and will provide
coverage with respect to Realized Losses that are (i) attributable to the
Mortgagor's failure to make any payment of principal or interest as required
under the Mortgage Note, but not including Special Hazard Losses, Extraordinary
Losses or other losses resulting from damage to a Mortgaged Property, Bankruptcy
Losses or Fraud Losses (any such loss, a 'Defaulted Mortgage Loss'); (ii) of a
type generally covered by a special hazard insurance policy (as defined below)
(any such loss, a 'Special Hazard Loss'); (iii) attributable to certain actions
which may be taken by a bankruptcy court in connection with a Mortgage Loan,
including a reduction by a bankruptcy court of the principal balance of or the
Mortgage Rate on a Mortgage Loan or an extension of its maturity (any such loss,
a 'Bankruptcy Loss'); and (iv) incurred on defaulted Mortgage Loans as to which
there was fraud in the origination of such Mortgage Loans (any such loss, a
'Fraud Loss'). Losses occasioned by war, civil insurrection, certain
governmental actions, nuclear reaction and certain other risks ('Extraordinary
Losses') will not be covered unless otherwise specified. To the extent that the
Credit Enhancement for any series of Securities is exhausted, the
Securityholders will bear all further risks of loss not otherwise insured
against.
 
     As set forth below and in the applicable Prospectus Supplement, Credit
Enhancement may be provided with respect to one or more classes of a series of
Securities or with respect to the Mortgage Assets in the related Trust. Credit
Enhancement may be in the form of (i) the subordination of one or more classes
of Subordinate Securities to provide credit support to one or more classes of
Senior Securities as described under 'Subordination,' (ii) the use of a mortgage
pool insurance policy, special hazard insurance policy, bankruptcy bond, reserve
fund, letter of credit, financial guaranty insurance policy, other third party
guarantees, another method of Credit Enhancement described in the related
Prospectus Supplement, or the use of a cross-support feature or

overcollateralization, or (iii) any combination of the foregoing. Unless
otherwise specified in the Prospectus Supplement, any Credit Enhancement will
not provide protection against all risks of loss and will not guarantee
repayment of the entire principal balance of the Securities and interest
thereon. If losses occur that exceed the amount covered by Credit Enhancement or
are not covered by the Credit Enhancement, holders of one or more classes of
Securities will bear their allocable share of deficiencies. If a form of Credit
Enhancement applies to several classes of Securities, and if principal payments
equal to the aggregate principal balances of certain classes will be distributed
prior to such distributions to the classes, the classes that receive such
distributions at a later time are more likely to bear any losses that exceed the
amount covered by Credit Enhancement.
 
     The amounts and type of Credit Enhancement arrangement as well as the
provider thereof, if applicable, with respect to each series of Securities will
be set forth in the related Prospectus Supplement. To the extent provided in the
applicable Prospectus Supplement and the Pooling and Servicing Agreement, the
Credit Enhancement arrangements may be periodically modified, reduced and
substituted for based on the aggregate outstanding principal balance of the
Mortgage Loans covered thereby. See 'Description of Credit
Enhancement--Reduction or Substitution of Credit Enhancement.' If specified in
the applicable Prospectus Supplement, Credit Enhancement for a series of
Securities may cover one or more other series of Securities.
 
                                       51
<PAGE>
     The descriptions of any insurance policies or bonds described in this
Prospectus or any Prospectus Supplement and the coverage thereunder do not
purport to be complete and are qualified in their entirety by reference to the
actual forms of such policies, copies of which are available upon request.
 
     Letter of Credit.  If any component of Credit Enhancement as to any series
of Securities is to be provided by a letter of credit (the 'Letter of Credit'),
a bank (the 'Letter of Credit Bank') will deliver to the Trustee an irrevocable
Letter of Credit. The Letter of Credit may provide direct coverage with respect
to the related Securities or, if specified in the related Prospectus Supplement,
support the Sponsor's or any other person's obligation pursuant to a Purchase
Obligation to make certain payments to the Trustee with respect to one or more
components of Credit Enhancement. The Letter of Credit Bank, as well as the
amount available under the Letter of Credit with respect to each component of
Credit Enhancement, will be specified in the applicable Prospectus Supplement.
The Letter of Credit will expire on the expiration date set forth in the related
Prospectus Supplement, unless earlier terminated or extended in accordance with
its terms. On or before each Payment Date, either the Letter of Credit Bank or
the Trustee (or other obligor under a Purchase Obligation) will be required to
make the payments specified in the related Prospectus Supplement after
notification from the Trustee, to be deposited in the related Distribution
Account, if and to the extent covered, under the applicable Letter of Credit.
 
     Mortgage Pool Insurance Policies.  Any mortgage pool insurance policy
('Mortgage Pool Insurance Policy') obtained by the Sponsor for each related
Trust Estate will be issued by the Pool Insurer named in the related Prospectus
Supplement. Each Mortgage Pool Insurance Policy will, subject to limitations
specified in the related Prospectus Supplement described below, cover Defaulted

Mortgage Losses in an amount equal to a percentage specified in the related
Prospectus Supplement (or in a Current Report on Form 8-K) of the aggregate
principal balance of the Mortgage Loans on the Cut-Off Date. As set forth under
'Maintenance of Credit Enhancement,' the Master Servicer will use reasonable
efforts to maintain the Mortgage Pool Insurance Policy and to present claims
thereunder to the Pool Insurer on behalf of itself, the Trustee and the
Securityholders. The Mortgage Pool Insurance Policies, however, are not blanket
policies against loss (typically, such policies do not cover Special Hazard
Losses, Fraud Losses and Bankruptcy Losses), since claims thereunder may only be
made respecting particular defaulted Mortgage Loans and only upon satisfaction
of certain conditions precedent described below due to a failure to pay
irrespective of the reason therefor.
 
     Special Hazard Insurance Policies.  Any insurance policy covering Special
Hazard Losses (a 'Special Hazard Insurance Policy') obtained by the Sponsor for
a Trust Estate will be issued by the insurer named in the related Prospectus
Supplement. Each Special Hazard Insurance Policy will, subject to limitations
described in the related Prospectus Supplement, protect holders of the related
series of Securities from (i) losses due to direct physical damage to a
Mortgaged Property other than any loss of a type covered by a hazard insurance
policy or a flood insurance policy, if applicable, and (ii) losses from partial
damage caused by reason of the application of the co-insurance clauses contained
in hazard insurance policies. See 'Hazard Insurance; Claims Thereunder.' A
Special Hazard Insurance Policy will not cover Extraordinary Losses. Aggregate
claims under a Special Hazard Insurance Policy will be limited to a maximum
amount of coverage, as set forth in the related Prospectus Supplement or in a
Current Report on Form 8-K. A Special Hazard Insurance Policy will provide that
no claim may be paid unless hazard and, if applicable, flood insurance on the
Mortgaged Property securing the Mortgage Loan has been kept in force and other
protection and preservation expenses have been paid by the Master Servicer.
 
     Subject to the foregoing limitations, in general a Special Hazard Insurance
Policy will provide that, where there has been damage to property securing a
foreclosed Mortgage Loan (title to which has been acquired by the insured) and
to the extent such damage is not covered by the hazard insurance policy or flood
insurance policy, if any, maintained by the Mortgagor or the Master Servicer or
the Sub-Servicer, the insurer will pay the lesser of (i) the cost of repair or
replacement of such property or (ii) up on transfer of the property to the
insurer, the unpaid principal balance of such Mortgage Loan at the time of
acquisition of such property by foreclosure or deed in lieu of foreclosure, plus
accrued interest at the Mortgage Rate to the date of claim settlement and
certain expenses incurred by the Master Servicer or the Sub-Servicer with
respect to such property. If the property is transferred to a third party in a
sale approved by the issuer of the Special Hazard Insurance Policy (the 'Special
Hazard Insurer'), the amount that the Special Hazard Insurer will pay will be
the amount under (ii) above reduced by the net proceeds of the sale of the
property.
 
                                       52
<PAGE>
     As indicated under 'Description of the Securities--Assignment of Mortgage
Loans' above and to the extent set forth in the related Prospectus Supplement,
coverage in respect of Special Hazard Losses for a series of Securities may be
provided, in whole or in part by a type of special hazard instrument other than

a Special Hazard Insurance Policy or by means of the special hazard
representation of the Sponsor.
 
     Bankruptcy Bonds.  In the event of a personal bankruptcy of a Mortgagor, it
is possible that the bankruptcy court may establish the value of the Mortgaged
Property of such Mortgagor at an amount less than the then-outstanding,
principal balance of the Mortgage Loan secured by such Mortgaged Property (a
'Deficient Valuation'). The amount of the secured debt then could be reduced to
such value, and, thus, the holder of such Mortgage Loan would become an
unsecured creditor to the extent the outstanding principal balance of such
Mortgage Loan exceeds the value assigned to the Mortgaged Property by the
bankruptcy court. In addition, certain other modifications of the terms of a
Mortgage Loan can result from a bankruptcy proceeding, including a reduction in
the amount of the monthly payment on the related Mortgage Loan or a reduction in
the mortgage interest rate (a 'Debt Service Reduction'; Debt Service Reductions
and Deficient Valuations, collectively referred to herein as 'Bankruptcy
Losses'). See 'Certain Legal Aspects of Mortgage Loans and Related
Matters--Anti-Deficiency Legislation and Other Limitations on Lenders.' Any
bankruptcy bond ('Bankruptcy Bond') to provide coverage for Bankruptcy Losses
for proceedings under the federal Bankruptcy Code obtained by the Sponsor for a
Trust Estate will be issued by an insurer named in the related Prospectus
Supplement. The level of coverage under each Bankruptcy Bond will be set forth
in the applicable Prospectus Supplement or in a Current Report on Form 8-K.
 
     Reserve Funds.  If so provided in the related Prospectus Supplement, the
Sponsor will deposit or cause to be deposited in an account (a 'Reserve Fund')
any combination of cash, one or more irrevocable letters of credit or one or
more Eligible Investments in specified amounts, amounts otherwise distributable
to Subordinate Securityholders or the owners of any Originator's Retained Yield,
or any other instrument satisfactory to the Rating Agency or Agencies, which
will be applied and maintained in the manner and under the conditions specified
in such Prospectus Supplement. In the alternate or in addition to such deposit
to the extent described in the related Prospectus Supplement, a Reserve Fund may
be funded through application of all or a portion of amounts otherwise payable
on any related Subordinate Securities from the Originator's Retained Yield or
otherwise. In addition, with respect to any series of Securities as to which
Credit Enhancement includes a Letter of Credit, if so specified in the related
Prospectus Supplement, under certain circumstances the remaining amount of the
Letter of Credit may be drawn by the Trustee and deposited in a Reserve Fund.
Amounts in a Reserve Fund may be distributed to Securityholders, or applied to
reimburse the Master Servicer for outstanding advances or may be used for other
purposes, in the manner and to the extent specified in the related Prospectus
Supplement. A Trust Estate may contain more than one Reserve Fund, each of which
may apply only to a specified class of Securities or to specified Mortgage
Assets.
 
     Financial Guaranty Insurance Policies.  If so specified in the related
Prospectus Supplement, a financial guaranty insurance policy or surety bond
('Financial Guaranty Insurance Policy') may be obtained and maintained for each
class or series of Securities. The issuer of any Financial Guaranty Insurance
Policy (a 'Financial Guaranty Insurer') will be described in the related
Prospectus Supplement. A copy of any such Financial Guaranty Insurance Policy
will be attached as an exhibit to the related Prospectus Supplement.
 

     Unless otherwise specified in the related Prospectus Supplement, a
Financial Guaranty Insurance Policy will unconditionally and irrevocably
guarantee to Securityholders that an amount equal to each full and complete
insured payment will be received by an agent of the Trustee (an 'Insurance
Paying Agent') on behalf of Securityholders, for distribution by the Trustee to
each Securityholder. The 'insured payment' will be defined in the related
Prospectus Supplement, and will generally equal the full amount of the
distributions of principal and interest to which Securityholders are entitled
under the related Pooling and Servicing Agreement plus any other amounts
specified therein or in the related Prospectus Supplement (the 'Insured
Payment').
 
     Financial Guaranty Insurance Policies may apply only to certain specified
classes, or may apply at the Mortgage Asset level and only to specified Mortgage
Assets.
 
     The specific terms of any Financial Guaranty Insurance Policy will be as
set forth in the related Prospectus Supplement. Financial Guaranty Insurance
Policies may have limitations including (but not limited to) limitations on the
insurer's obligation to guarantee the obligations of the Originators to
repurchase or substitute for any
 
                                       53
<PAGE>
Mortgage Loans, Financial Guaranty Insurance Policies will not guarantee any
specified rate of prepayments and/or to provide funds to redeem Securities on
any specified date.
 
     Subject to the terms of the related Pooling and Servicing Agreement, the
Financial Guaranty Insurer may be subrogated to the rights of each
Securityholder to receive payments under the Securities to the extent of any
payment by such Financial Guaranty Insurer under the related Financial Guaranty
Insurance Policy.
 
     Other Insurance, Guarantees and Similar Instruments or Agreements.  If
specified in the related Prospectus Supplement, a Trust may include in lieu of
some or all of the foregoing or in addition thereto third party guarantees, and
other arrangements for maintaining timely payments or providing additional
protection against losses on all or any specified portion of the assets included
in such Trust, paying administrative expenses, or accomplishing such other
purpose as may be described in the Prospectus Supplement. The Trust may include
a guaranteed investment contract or reinvestment agreement pursuant to which
funds held in one or more accounts will be invested at a specified rate. If any
class of Securities has a floating interest rate, or if any of the Mortgage
Assets has a floating interest rate, the Trust may include an interest rate swap
contract, an interest rate cap agreement or similar contract providing limited
protection against interest rate risks.
 
     Cross Support.  If specified in the Prospectus Supplement, the beneficial
ownership of separate groups of assets included in a Trust may be evidenced by
separate classes of the related series of Securities. In such case, credit
support may be provided by a cross-support feature which requires that
distributions be made with respect to one class of Securities may be made from
excess amounts available from other asset groups within the same Trust which

support other classes of Securities. The Prospectus Supplement for a series that
includes a cross-support feature will describe the manner and conditions for
applying such cross-support feature.
 
     If specified in the Prospectus Supplement, the coverage provided by one or
more forms of credit support may apply concurrently to two or more separate
Trusts. If applicable, the Prospectus Supplement will identify the Trusts to
which such credit support relates and the manner of determining the amount of
the coverage provided thereby and of the application of such coverage to the
identified Trusts.
 
     Overcollateralization.  If specified in the Prospectus Supplement,
subordination provisions of a Trust may be used to accelerate to a limited
extent the amortization of one or more classes of Securities relative to the
amortization of the related Mortgage Loans. The accelerated amortization is
achieved by the application of certain excess interest to the payment of
principal of one or more classes of Securities. This acceleration feature
creates, with respect to the Mortgage Loans or groups thereof, over
collateralization which results from the excess of the aggregate principal
balance of the related Mortgage Loans, or a group thereof, over the principal
balance of the related class of Securities. Such acceleration may continue for
the life of the related Security, or may be limited. In the case of limited
acceleration, once the required level of overcollateralization is reached, and
subject to certain provisions specified in the related Prospectus Supplement,
such limited acceleration feature may cease, unless necessary to maintain the
required level of overcollateralization.
 
     Maintenance of Credit Enhancement.  To the extent that the applicable
Prospectus Supplement does not expressly provide for Credit Enhancement
arrangements in lieu of some or all of the arrangements mentioned below, the
following paragraphs shall apply.
 
     If a form of Credit Enhancement has been obtained for a series of
Securities, the Sponsor will be obligated to exercise its best reasonable
efforts to keep or cause to be kept such form of credit support in full force
and effect throughout the term of the applicable Pooling and Servicing
Agreement, unless coverage thereunder has been exhausted through payment of
claims or otherwise, or substitution therefor is made as described below under
'Reduction or Substitution of Credit Enhancement.'
 
     In lieu of the Sponsor's obligation to maintain a particular form of Credit
Enhancement, the Sponsor may obtain a substitute or alternate form of Credit
Enhancement. If the Master Servicer obtains such a substitute form of Credit
Enhancement, it will maintain and keep such form of Credit Enhancement in full
force and effect as provided herein. Prior to its obtaining any substitute or
alternate form of Credit Enhancement, the Sponsor will obtain written
confirmation from the Rating Agency or Agencies that rated the related series of
Securities that the substitution or alternate form of Credit Enhancement for the
existing Credit Enhancement will not adversely affect the then-current ratings
assigned to such Securities by such Rating Agency or Agencies.
 
                                       54
<PAGE>
     The Master Servicer, on behalf of itself, the Trustee and Securityholders,

will provide the Trustee information required for the Trustee to draw under a
Letter of Credit or Financial Guaranty Insurance Policy, will present claims to
each Pool Insurer, to the issuer of each Special Hazard Insurance Policy or
other special hazard instrument, to the issuer of each Bankruptcy Bond and will
take such reasonable steps as are necessary to permit recovery under such Letter
of Credit, Financial Guaranty Insurance Policy, Purchase Obligation, insurance
policies or comparable coverage respecting defaulted Mortgage Loans or Mortgage
Loans which are the subject of a bankruptcy proceeding. Additionally, the Master
Servicer will present such claims and take such steps as are reasonably
necessary to provide for the performance by another party of its Purchase
Obligation. As set forth above, all collections by the Master Servicer under any
Purchase Obligation, any Mortgage Pool Insurance Policy, or any Bankruptcy Bond
and, where the related property has not been restored, any Special Hazard
Insurance Policy, are to be deposited initially in the Principal and Interest
Account and ultimately in the Distribution Account, subject to withdrawal as
described above. All draws under any Letter of Credit or Financial Guaranty
Insurance Policy will be deposited directly in the Distribution Account.
 
     If any property securing a defaulted Mortgage Loan is damaged and proceeds,
if any, from the related hazard insurance policy or any applicable Special
Hazard Instrument are insufficient to restore the damaged property to a
condition sufficient to permit recovery under any applicable form of Credit
Enhancement, the Master Servicer is not required to expend its own funds to
restore the damaged property unless it determines (i) that such restoration will
increase the proceeds to one or more classes of Securityholders on liquidation
of the Mortgage Loan after reimbursement of the Master Servicer for its expenses
and (ii) that such expenses will be recoverable by it through Liquidation
Proceeds or Insurance Proceeds. If recovery under any applicable form of Credit
Enhancement is not available because the Master Servicer has been unable to make
the above determinations, has made such determinations incorrectly or recovery
is not available for any other reason, the Master Servicer is nevertheless
obligated to follow such normal practices and procedures (subject to the
preceding sentence) as it deems necessary or advisable to realize upon the
defaulted Mortgage Loan and in the event such determination has been incorrectly
made, is entitled to reimbursement of its expenses in connection with such
restoration.
 
     Reduction or Substitution of Credit Enhancement.  Unless otherwise
specified in the related Prospectus Supplement, the amount of credit support
provided pursuant to any of the Credit Enhancements (including, without
limitation, a Mortgage Pool Insurance Policy, Financial Guaranty Insurance
Policy, Special Hazard Insurance Policy, Bankruptcy Bond, Letter of Credit, or
any alternative form of Credit Enhancement) may be reduced under certain
specified circumstances. In addition, if so described in the related Prospectus
Supplement, any formula used in calculating the amount or degree of Credit
Enhancement may be changed without the consent of the Securityholders upon
written confirmation from each Rating Agency then rating the Securities that
such change will not adversely affect the then-current rating or ratings
assigned to the Securities. In most cases, the amount available pursuant to any
Credit Enhancement will be subject to periodic reduction in accordance with a
schedule or formula on a nondiscretionary basis pursuant to the terms of the
related Pooling and Servicing Agreement as the aggregate outstanding principal
balance of the Mortgage Loans declines. Additionally, in certain cases, such
credit support (and any replacements therefor) may be replaced, reduced or

terminated upon the written assurance from each applicable Rating Agency that
the then-current rating of the related series of Securities will not be
adversely affected. Furthermore, in the event that the credit rating of any
obligor under any applicable Credit Enhancement is downgraded, the credit rating
of the related Securities may be downgraded to a corresponding level, and,
unless otherwise specified in the related Prospectus Supplement, the Sponsor
thereafter will not be obligated to obtain replacement credit support in order
to restore the rating of the Securities, and also will be permitted to replace
such credit support with other Credit Enhancement instruments issued by obligors
whose credit ratings are equivalent to such downgraded level and in lower
amounts which would satisfy such downgraded level, provided that the
then-current, albeit downgraded, rating of the related series of Securities is
maintained. Where the credit support is in the form of a Reserve Fund, a
permitted reduction in the amount of Credit Enhancement will result in a release
of all or a portion of the assets in the Reserve Fund to the Sponsor, the Master
Servicer, one or more Originators or such other person that is entitled thereto.
Any assets so released will not be available to fund distribution obligations in
future periods.

<PAGE>
                      HAZARD INSURANCE; CLAIMS THEREUNDER
 
     Each Mortgage Loan will be required to be covered by a hazard insurance
policy (as described below). The following is only a brief description of
certain insurance policies and does not purport to summarize or describe all of
the provisions of these policies. Such insurance is subject to underwriting and
approval of individual Mortgage Loans by the respective insurers. The
descriptions of any insurance policies described in this Prospectus or any
Prospectus Supplement and the coverage thereunder do not purport to be complete
and are qualified in their entirety by reference to such forms of policies,
sample copies of which are available from the Trustee upon request.
 
HAZARD INSURANCE POLICIES
 
     The terms of the Mortgage Loans require each Mortgagor to maintain a hazard
insurance policy for the Mortgage Loan. Additionally, the Pooling and Servicing
Agreement will require the Master Servicer to cause to be maintained with
respect to each Mortgage Loan a hazard insurance policy with a generally
acceptable carrier that provides for fire and extended coverage relating to such
Mortgage Loan in an amount not less than the least of (i) the outstanding
principal balance of the Mortgage Loan, (ii) the minimum amount required to
compensate for damage or loss on a replacement cost basis or (iii) the full
insurable value of the premises.
 
     If a Mortgage Loan at the time of origination relates to a Mortgaged
Property in an area identified in the Federal Register by the Federal Emergency
Management Agency as having special flood hazards, the Master Servicer will be
required to maintain with respect thereto a flood insurance policy in a form
meeting the requirements of the then-current guidelines of the Federal Insurance
Administration with a generally acceptable carrier in an amount representing
coverage, and which provides for recovery by the Master Servicer on behalf of
the Trust of insurance proceeds relating to such Mortgage Loan of not less than
the least of (i) the outstanding principal balance of the Mortgage Loan, (ii)

the minimum amount required to compensate for damage or loss on a replacement
cost basis, (iii) the maximum amount of insurance that is available under the
Flood Disaster Protection Act of 1973. Pursuant to the related Pooling and
Servicing Agreement, the Master Servicer will be required to indemnify the Trust
out of the Master Servicer's own funds for any loss to the Trust resulting from
the Master Servicer's failure to maintain such flood insurance.
 
     In the event that the Master Servicer obtains and maintains a blanket
policy insuring against fire with extended coverage and against flood hazards on
all of the Mortgage Loans, then, to the extent such policy names the Master
Servicer as loss payee and provides coverage in an amount equal to the aggregate
unpaid principal balance on the Mortgage Loans without co-insurance, and
otherwise complies with the requirements of the Pooling and Servicing Agreement,
the Master Servicer shall be deemed conclusively to have satisfied its
obligations with respect to fire and hazard insurance coverage under the Pooling
and Servicing Agreement. Such blanket policy may contain a deductible clause, in
which case the Master Servicer will be required, in the event that there shall
not have been maintained on the related Mortgaged Property a policy complying
with the Pooling and Servicing Agreement, and there shall have been a loss that
would have been covered by such policy, to deposit in the Principal and Interest
Account from the Master Servicer's own funds the difference, if any, between the
amount that would have been payable under a policy complying with the Pooling
and Servicing Agreement and the amount paid under such blanket policy.
 
                         THE SPONSOR AND THE TRANSFEROR
 
     The Sponsor, ADVANTA Mortgage Conduit Services, Inc., was incorporated in
the State of Delaware in April, 1993. It is a direct subsidiary of the Master
Servicer, Advanta Mortgage Corp. USA, in addition to ADVANTA Mortgage Corp.
Midatlantic, ADVANTA Mortgage Corp., Midatlantic II, ADVANTA Mortgage Corp.
Midwest, ADVANTA Mortgage Corp. of New Jersey and ADVANTA Mortgage Corp.

     The Sponsor maintains its principal office at 16875 West Bernardo Drive,
San Diego, California 92127. Its telephone number is (619) 674-1800.
 
     The Transferor, ADVANTA Mortgage Receivables Inc., was incorporated in the

and was formed as a special purpose finance subsidiary to
 
                                       56
<PAGE>
facilitate certain issuances of Securities. The use of the Transferor will not
affect the obligations of the Sponsor with respect to the related Trust or the
related Securities. If the Transferor is to be involved in a particular offering
the related Prospectus Supplement will describe its role in such offering; for
purposes of this Prospectus the role of the Transferor is subsumed in the role
of the Sponsor.
 
     The Transferor maintains its principal office at Brandywine Corporate
Center, 650 Naamans Road, Claymont, Delaware 19703. Its telephone number is

                              THE MASTER SERVICER
 
     Unless otherwise specified in the related Prospectus Supplement, ADVANTA
Mortgage Corp. USA will act as the Master Servicer for a series of Securities.
 
     ADVANTA Mortgage Corp. USA was acquired by ADVANTA Corp., a Delaware
corporation ('ADVANTA Parent') in September, 1986 and is an indirect subsidiary
of ADVANTA Parent. The Master Servicer is an affiliate of Colonial National Bank

corporation incorporated in 1983. It is a nationwide servicer of first and
junior mortgage loans. ADVANTA Mortgage Corp. USA has centralized servicing
functions located in San Diego, California. This provides for economies of scale
and a depth of appraisal, attorney and realtor contacts throughout the country.
 
                      THE POOLING AND SERVICING AGREEMENT
 
     As described above under 'Description of the Securities--General,' each
series of Securities will be issued pursuant to a Pooling and Servicing
Agreement as described in that section. The following summaries describe certain
additional provisions common to each Pooling and Servicing Agreement.
 
SERVICING AND OTHER COMPENSATION AND PAYMENT OF EXPENSES; ORIGINATOR'S RETAINED
YIELD
 
     Each servicer, whether the Master Servicer or any Sub-Servicer (either the
Master Servicer or any Sub-Servicer being a 'Servicer'), will retain a fee in
connection with its servicing activities for each series of Securities equal to
the percentage per annum specified in the related Prospectus Supplement or
Current Report on Form 8-K (the 'Base Servicing Fee'), generally payable monthly
with respect to each Mortgage Loan directly serviced by such Servicer at
one-twelfth the annual rate, of the then-outstanding principal amount of each
such Mortgage Loan as of the first day of each calendar month. The Master
Servicer acting as master servicer with respect to Mortgage Loans being serviced
directly by a Sub-Servicer will retain a fee equal to the percentage per annum
specified in the related Prospectus Supplement or Current Report on Form 8-K
('Master Servicing Fee'), generally payable monthly on one-twelfth the annual
rate, of the then-outstanding principal amount of each such Mortgage Loan as of
the first day of each calendar month. The Base Servicing Fees and the Master
Servicing Fee are collectively referred to as the 'Servicing Fee.'
 
     In addition to the Base Servicing Fee, each Servicer will generally be
entitled under the Pooling and Servicing Agreement to retain additional
servicing compensation in the form of prepayment charges, release fees, bad
check charges, assumption fees, late payment charges, or any other
servicing-related fees, Net Liquidation Proceeds not required to be deposited in
the Principal and Interest Account pursuant to the Pooling and Servicing
Agreement, and similar items.
 
     Unless otherwise specified in the related Prospectus Supplement, the Master
Servicer will pay or cause to be paid certain ongoing expenses associated with
each Trust Estate and incurred by it in connection with its responsibilities

under the Pooling and Servicing Agreement, including, without limitation,
payment of any fee or other amount payable in respect of any alternative Credit
Enhancement arrangements, payment of the fees and disbursements of the Trustee
or accountant, any custodian appointed by the Trustee, the Security Registrar
and any Paying Agent, and payment of expenses incurred in enforcing the
obligations of Sub-Servicers and Originators. The Master Servicer may be
entitled to reimbursement of expenses incurred in enforcing the
 
                                       57
<PAGE>
obligations of Sub-Servicers and Originators under certain limited
circumstances. In addition, as indicated in the preceding section, the Master
Servicer will be entitled to reimbursements for certain expenses incurred by it
in connection with Liquidated Mortgage Loans and in connection with the
restoration of Mortgaged Properties, such right of reimbursement being prior to
the rights of Securityholders to receive any related Liquidation Proceeds
(including Insurance Proceeds).
 
     The Prospectus Supplement for a series of Securities will specify if there
will be any Originator's Retained Yield retained. Any such Originator's Retained
Yield will be a specified portion of the interest payable on each Mortgage Loan
in a Mortgage Pool. Any such Originator's Retained Yield will be established on
a loan-by-loan basis and the amount thereof with respect to each Mortgage Loan
in a Mortgage Pool will be specified on an exhibit to the related Pooling and
Servicing Agreement. Any Originator's Retained Yield in respect of a Mortgage
Loan will represent a specified portion of the interest payable thereon and will
not be part of the related Trust Estate. Any partial recovery of interest in
respect of a Mortgage Loan will be allocated between the owners of any
Originator's Retained Yield and the holders of classes of Securities entitled to
payments of interest as provided in the Prospectus Supplement and the applicable
Pooling and Servicing Agreement.
 
EVIDENCE AS TO COMPLIANCE
 
     Each Pooling and Servicing Agreement will require the Master Servicer to
deliver annually to the Trustee and any Credit Enhancer, an officers'
certificate stating, as to each signer thereof, that (i) a review of the
activities of the Master Servicer during such preceding year and of performance
under the related Pooling and Servicing Agreement has been made under such
officers' supervision, and (ii) to the best of such officers' knowledge, based
on such review, the Master Servicer has fulfilled all its obligations under the
related Pooling and Servicing Agreement for such year, or, if there has been a
default in the fulfillment of any such obligations, specifying each such default
known to such officers and the nature and status thereof including the steps
being taken by the Master Servicer to remedy such defaults.
 
     Each Pooling and Servicing Agreement will require the Master Servicer to
cause to be delivered to the Trustee and any Credit Enhancer a letter or letters
of a firm of independent, nationally recognized certified public accountants
reasonably acceptable to the Credit Enhancer, if applicable, stating that such
firm has, with respect to the Master Servicer's overall servicing operations (i)
performed applicable tests in accordance with the compliance testing procedures
as set forth in Appendix 3 of the Audit Guide for Audits of HUD Approved
Nonsupervised Mortgagees or (ii) examined such operations in accordance with the

requirements of the Uniform Single Attestation Program for Mortgage Bankers, and
in either case stating such firm's conclusions relating thereto.
 
     Copies of the annual accountants' statement and the annual statement of
officers of the Master Servicer may be obtained by Securityholders without
charge upon written request to the Master Servicer.
 
REMOVAL AND RESIGNATION OF THE MASTER SERVICER
 
     Unless otherwise specified in the related Prospectus Supplement, each
Pooling and Servicing Agreement will provide that the Master Servicer may not
resign from its obligations and duties thereunder, except in connection with a
permitted transfer of servicing, unless such duties and obligations are no
longer permissible under applicable law or are in material conflict by reason of
applicable law with any other activities of a type and nature presently carried
on by it. No such resignation will become effective until the Trustee has
assumed the Master Servicer's obligations and duties under the Pooling and
Servicing Agreement. The Trustee, the Securityholders or a Credit Enhancer, if
applicable, will have the right, pursuant to the related Pooling and Servicing
Agreement, to remove the Master Servicer upon the occurrence of any of (a)
certain events of insolvency, readjustment of debt, marshalling 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; (b) the failure of the Master Servicer to perform any one or more
of its material obligations under the Pooling and Servicing Agreement as to
which the Master Servicer shall continue in default with respect thereto for a
specified period, generally of sixty (60) days, after notice by the Trustee or
any Credit Enhancer (if required by the Pooling and Servicing Agreement) of said
failure; or (c) the failure of the Master Servicer to cure any breach of any of
its representations and warranties set forth in the Pooling and Servicing
Agreement which materially and adversely
 
                                       58
<PAGE>
affects the interests of the Securityholders or any Credit Enhancer, for a
specified period, generally of thirty (30) days after the Master Servicer's
discovery or receipt of notice thereof.
 
     The Pooling and Servicing Agreement may also provide that the related
Credit Enhancer may remove the Master Servicer upon the occurrence of any of
certain events including:
 
          (i) with respect to any Payment Date, if the total available funds
     with respect to the Mortgage Loans Group will be less than the related
     distribution amount on the class of credit-enhanced securities in respect
     of such Payment Date; provided, however, that the Credit Enhancer generally
     will have no right to remove the Master Servicer pursuant to the provision
     described in this clause (i) if the Master Servicer can demonstrate to the
     reasonable satisfaction of the Credit Enhancer that such event was due to
     circumstances beyond the control of the Master Servicer;
 
          (ii) the failure by the Master Servicer to make any required Servicing
     Advance;
 

          (iii) the failure of the Master Servicer to perform one or more of its
     material obligations under the Pooling and Servicing Agreement; or
 
          (iv) the failure by the Master Servicer to make any required
     Delinquency Advance or to pay any Compensating Interest;
 
provided, however, that prior to any removal of the Master Servicer by the
related Credit Enhancer pursuant to clauses (i), (ii) or (iii) above the Master
Servicer shall first have been given by the related Credit Enhancer notice of
the occurrence of one or more of the events set forth in clauses (i) or (ii)
above and the Master Servicer shall not have remedied, or shall not have taken
action satisfactory to such Credit Enhancer to remedy, such event or events
within a specified period, generally 30 days (60 days with respect to clause
(iii)) after the Master Servicer's receipt of such notice; and provided, further
that in the event of the refusal or inability of the Master Servicer to make any
required Delinquency Advance or to pay any Compensating Interest as described in
clause (iv) above, such removal shall be effective (without the requirement of
any action on the part of such Credit Enhancer or of the Trustee) not later than
a shorter specified period, generally not in excess of five business days,
following the day on which the Trustee notifies an authorized officer of the
Master Servicer that a required Delinquency Advance or to pay any Compensating
Interest has not been received by the Trustee.
 
AMENDMENTS
 
     The Trustee, the Sponsor and the Master Servicer may at any time and from
time to time, with the prior approval of the related Credit Enhancer, if
required, but without the giving of notice to or the receipt of the consent of
the Securityholders, amend a Pooling and Servicing Agreement, and the Trustee
will be required to consent to such amendment, for the purposes of (x) (i)
curing any ambiguity, or correcting or supplementing any provision of such
Pooling and Servicing Agreement which may be inconsistent with any other
provision of the Pooling and Servicing Agreement, (ii) in connection with a
Trust making REMIC elections, if accompanied by an approving opinion of counsel
experienced in federal income tax matters, removing the restriction against the
transfer of a REMIC residual security to a Disqualified Organization (as such
term is defined in the Code) or (iii) complying with the requirements of the
Code and the regulations proposed or promulgated thereunder; provided, however,
that such action shall not, as evidenced by an opinion of counsel delivered to
the Trustee, materially and adversely affect the interests of any Securityholder
(without its written consent) or (y) such other purposes set forth in the
related Pooling and Servicing Agreement.
 
     Unless otherwise specified in the related Prospectus Supplement, each
Pooling and Servicing Agreement may also be amended by the Trustee, the Sponsor
and the Master Servicer at any time and from time to time, with the prior
written approval of the related Credit Enhancer, if required, and not less than
a majority of the Percentage Interest represented by each related class of
Securities then outstanding, for the purpose of adding any provisions or
changing in any manner or eliminating any of the provisions of such Pooling and
Servicing Agreement or of modifying in any manner the rights of the
Securityholders thereunder; provided, however, that no such amendment shall (a)
change in any manner the amount of, or delay the timing of, payments which are
required to be distributed to any Securityholders without the consent of the

holder of such Security or (b) change the aforesaid percentages of Percentage
Interest which are required to consent to any such amendments, without the
consent of the holders of all Securities of the class or classes affected then
outstanding.
 
                                       59
<PAGE>
TERMINATION; RETIREMENT OF SECURITIES
 
     Unless otherwise specified in the related Prospectus Supplement, each
Pooling and Servicing Agreement will provide that a Trust will terminate upon
the earlier of (i) the payment to the Securityholders of all Securities issued
by the Trust from amounts other than those available under, if applicable, the
related Credit Enhancement of all amounts required to be paid to such
Securityholders upon the later to occur of (a) the final payment or other
liquidation (or any advance made with respect thereto) of the last Mortgage Loan
in the Trust Estate or (b) the disposition of all property acquired in respect
of any Mortgage Loan remaining in the Trust Estate, (ii) any time when a
Qualified Liquidation (as defined in the Code) of the Trust Estate (if the
related Trust is a REMIC) is effected. In no event, however, will the trust
created by the Pooling and Servicing Agreement continue beyond the expiration of
21 years from the death of the survivor of certain persons named in such Pooling
and Servicing Agreement. Written notice of termination of the Pooling and
Servicing Agreement will be given to each Securityholder, and the final
distribution will be made only upon surrender and cancellation of the Securities
at an office or agency appointed by the Trustee that will be specified in the
notice of termination. If the Securityholders are permitted to terminate the
trust under the applicable Pooling and Servicing Agreement, a penalty may be
imposed upon the Securityholders based upon the fee that would be foregone by
the Master Servicer because of such termination.
 
     Any purchase of Mortgage Loans and property acquired in respect of Mortgage
Loans evidenced by a series of Securities shall be made at the option of the
Master Servicer, the Sponsor or, if applicable, the holder of the REMIC Residual
Securities at the price specified in the related Prospectus Supplement. The
exercise of such right will effect earlier than expected retirement of the
Securities of that series, but the right of the Master Servicer, the Sponsor or,
if applicable, such holder to so purchase is, unless otherwise specified in the
applicable Prospectus Supplement, subject to the aggregate principal balance of
the Mortgage Loans for that series as of any Remittance Date being less than the
percentage specified in the related Prospectus Supplement of the aggregate
principal balance of the Mortgage Loans at the Cut-Off Date for that series. The
Prospectus Supplement for each series of Securities will set forth the amounts
that the holders of such Securities will be entitled to receive upon such
earlier than expected retirement. If a REMIC election has been made, the
termination of the related Trust Estate will be effected in a manner consistent
with applicable federal income tax regulations and its status as a REMIC.
 
THE TRUSTEE
 
     The Trustee under each Pooling and Servicing Agreement will be named in the
related Prospectus Supplement. Each Pooling and Servicing Agreement will provide
that the Trustee shall be under no obligation to exercise any of the rights or
powers vested in it by the Pooling and Servicing Agreement at the request or

direction of any of the Securityholders, unless such Securityholders shall have
offered to the 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 Trustee may execute any of the trusts or powers granted by each Pooling
and Servicing Agreement or perform any duties thereunder either directly or by
or through agents or attorneys, and the Trustee will not be responsible for any
misconduct or negligence on the part of any agent or attorney appointed and
supervised with due care by it thereunder.
 
     Pursuant to each Pooling and Servicing Agreement, the Trustee will not be
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 Pooling and Servicing Agreement.
 
     Unless otherwise described in the related Prospectus Supplement, each
Pooling and Servicing Agreement will permit the removal of the Trustee upon the
occurrence and continuance of one of the following events:
 
          (1) the Trustee shall fail to distribute to the Securityholders
     entitled thereto on any Payment Date amounts available for distribution in
     accordance with the terms of the Pooling and Servicing Agreement; or
 
          (2) the Trustee shall default in the performance of, or breach, any
     covenant or agreement of the Trustee in the Pooling and Servicing
     Agreement, or if any representation or warranty of the Trustee made in the
     Pooling and Servicing Agreement or in any certificate or other writing
     delivered pursuant thereto or in
 
                                       60
<PAGE>
     connection therewith shall prove to be incorrect in any material respect as
     of the time when the same shall have been made, and such default or breach
     shall continue or not be cured for the period then specified in the related
     Pooling and Servicing Agreement after the Trustee shall have received
     notice specifying such default or breach and requiring it to be remedied;
     or
 
          (3) a decree or order of a court or agency or supervisory authority
     having jurisdiction for the appointment of a conservator or receiver or
     liquidator in any insolvency, readjustment of debt, marshalling of assets
     and liabilities or similar proceedings, or for the winding-up or
     liquidation of its affairs, shall have been entered against the Trustee,
     and such decree or order shall have remained in force undischarged or
     unstayed for the period then specified in the related Pooling and Servicing
     Agreement; or
 
          (4) a conservator or receiver or liquidator or sequestrator or
     custodian of the property of the Trustee is appointed in any insolvency,
     readjustment of debt, marshalling of assets and liabilities or similar
     proceedings of or relating to the Trustee or relating to all or
     substantially all of its property; or
 

          (5) the Trustee shall become insolvent (however insolvency is
     evidenced), generally fail to pay its debts as they come due, file or
     consent to the filing of a petition to take advantage of any applicable
     insolvency or reorganization statute, make an assignment for the benefit of
     its creditors, voluntarily suspend payment of its obligations, or take
     corporate action for the purpose of any of the foregoing.
 
     If an event described above occurs and is continuing, then, and in every
such case (i) the Sponsor, (ii) the Securityholders (on the terms set forth in
the related Pooling and Servicing Agreement), or (iii) if there is a Credit
Enhancer, such Credit Enhancer may, whether or not the Trustee has resigned,
immediately, concurrently with the giving of notice to the Trustee, and without
delay, appoint a successor Trustee pursuant to the terms of the Pooling and
Servicing Agreement.
 
     No Securityholder will have any right to institute any proceeding, judicial
or otherwise, with respect to a Pooling and Servicing Agreement or any Credit
Enhancement, if applicable, or for the appointment of a receiver or trustee, or
for any other remedy under the Pooling and Servicing Agreement, unless:
 
          (1) such Securityholder has previously given written notice to the
     Sponsor and the Trustee of such Securityholder's intention to institute
     such proceeding;
 
          (2) the Securityholders of not less than 25% of the Percentage
     Interests represented by certain specified classes of Securities then
     outstanding shall have made written request to the Trustee to institute
     such proceeding;
 
          (3) such Securityholder or Securityholders have offered to the Trustee
     reasonable indemnity, against the costs, expenses and liabilities to be
     incurred in compliance with such request;
 
          (4) the Trustee for the period specified in the related Pooling and
     Servicing Agreement, generally not in excess of 60 days after receipt of
     such notice, request and offer of indemnity, has failed to institute such
     proceeding;
 
          (5) as long as such action affects any credit-enhanced class of
     Securities outstanding, the related Credit Enhancer has consented in
     writing thereto; and
 
          (6) no direction inconsistent with such written request has been given
     to the Trustee during such specified period by the Securityholders of a
     majority of the Percentage Interests represented by certain specified
     classes of Securities.
 
     No one or more Securityholders will have any right in any manner whatever
by virtue of, or by availing themselves of, any provision of the Pooling and
Servicing Agreement to affect, disturb or prejudice the rights of any other
Securityholder of the same class or to obtain or to seek to obtain priority or
preference over any other Securityholder of the same class or to enforce any
right under the Pooling and Servicing Agreement, except in the manner provided
in the Pooling and Servicing Agreement and for the equal and ratable benefit of

all of the Securityholders of the same class.
 
     In the event the Trustee receives conflicting or inconsistent requests and
indemnity from two or more groups of Securityholders, each representing less
than a majority of the applicable class of Securities, the Trustee in its
 
                                       61
<PAGE>
sole discretion may determine what action, if any, shall be taken,
notwithstanding any other provision of the Pooling and Servicing Agreement.
 
     Notwithstanding any other provision in the Pooling and Servicing Agreement,
the Securityholder of any Security has the right, which is absolute and
unconditional, to receive distributions to the extent provided in the Pooling
and Servicing Agreement with respect to such Security or to institute suit for
the enforcement of any such distribution, and such right shall not be impaired
without the consent of such Security.
 
     Either (i) the Securityholders of a majority of the Percentage Interests
represented by certain specified classes of Securities then outstanding or (ii)
if there is a Credit Enhancer, such Credit Enhancer may direct the time, method
and place of conducting any proceeding for any remedy available to the Sponsor
with respect to the Certificates or exercising any trust or power conferred on
the Trustee with respect to such Certificates; provided that:
 
          (1) such direction shall not be in conflict with any rule of law or
     with a Pooling and Servicing Agreement;
 
          (2) the Sponsor or the Trustee, as the case may be, shall have been
     provided with indemnity satisfactory to them; and
 
          (3) the Sponsor or the Trustee, as the case may be, may take any other
     action deemed proper by the Trustee which is not inconsistent with such
     direction; provided, however, that the Sponsor or the Trustee, as the case
     may be, need not take any action which they determine might involve them in
     liability or may be unjustly prejudicial to the Securityholders not so
     directing.
 
     The Trustee will be liable under the Pooling and Servicing Agreement only
to the extent of the obligations specifically imposed upon and undertaken by the
Trustee therein. Neither the Trustee nor any of the directors, officers,
employees or agents of the Trustee will be under any liability on any Security
or otherwise to any Account, the Sponsor, the Master Servicer or any
Securityholder for any action taken or for refraining from the taking of any
action in good faith under a Pooling and Servicing Agreement, or for errors in
judgment; provided, however, that such provision shall not protect the Trustee
or any such person against any liability which would otherwise be imposed by
reason of negligent action, negligent failure to act or willful misconduct in
the performance of duties or by reason of reckless disregard of obligations and
duties thereunder.

                              YIELD CONSIDERATIONS
 
     The yield to maturity of a Security will depend on the price paid by the
holder for such Security, the Pass-Through Rate on any such Security entitled to
payments of interest (which Pass-Through Rate may vary if so specified in the
related Prospectus Supplement) and the rate of payment of principal on such
Security (or the rate at which the notional amount thereof is reduced if such
Security is not entitled to payments of principal) and other factors.
 
     Each month the interest payable on an actuarial type of Mortgage Loan will
be calculated as one-twelfth of the applicable Mortgage Rate multiplied by the
principal balance of such Mortgage Loan outstanding as of a specified day,
usually the first day of the month prior to the month in which the Payment Date
for the related series of Securities occurs, after giving effect to the payment
of principal due on such day, subject to any Deferred Interest. With respect to
date of payment Mortgage Loans, interest is charged to the Mortgagor at the
Mortgage Rate on the outstanding principal balance of such Note and calculated
based on the number of days elapsed between receipt of the Mortgagor's last
payment through receipt of the Mortgagor's most current payments. The amount of
such payments with respect to each Mortgage Loan distributed (or accrued in the
case of Deferred Interest or Accrual Securities) either monthly, quarterly or
semi-annually to holders of a class of Securities entitled to payments of
interest will be similarly calculated on the basis of such class' specified
percentage of each such payment of interest (or accrual in the case of Accrual
Securities) and will be expressed as a fixed, adjustable or variable
Pass-Through Rate payable on the outstanding principal balance or notional
amount of such Security, calculated as described herein and in the related
Prospectus Supplement. Holders of Strip Securities or a class of Securities
having a fixed Pass-Through Rate that varies based on the weighted average
Mortgage Rate of the underlying Mortgage Loans will be affected by
disproportionate prepayments and repurchases of Mortgage Loans having higher Net
Mortgage Rates or rates applicable to the Strip Securities, as applicable.
 
     The effective yield to maturity to each holder of fixed-rate Securities
entitled to payments of interest will be below that otherwise produced by the
applicable Pass-Through Rate and purchase price of such Security because, while
interest will accrue on each Mortgage Loan from the first day of each month, the
distribution of such interest will be made on the 25th day (or, if such day is
not a business day, the next succeeding business day) of the month (or, in the
case of quarterly-pay Securities, the twenty-fifth day of every third month, or,
in the case of semi-annual-pay Securities, the twenty-fifth day of every sixth
month) following the month of accrual.
 
     A class of Securities may be entitled to payments of interest at a fixed
Pass-Through Rate specified in the related Prospectus Supplement, a variable
Pass-Through Rate or adjustable Pass-Through Rate calculated based on the
weighted average of the Mortgage Rates (net of Servicing Fees and any
Originator's Retained Yield (each, a 'Net Mortgage Rate')) of the related
Mortgage Loans for the designated periods preceding the Payment Date if so
specified in the related Prospectus Supplement, or at such other variable rate
as may be specified in the related Prospectus Supplement.
 
     As will be described in the related Prospectus Supplement, the aggregate
payments of interest on a class of Securities, and the yield to maturity

thereon, will be effected by the rate of payment of principal on the Securities
(or the rate of reduction in the notional balance of Securities entitled only to
payments of interest) and, in the case of Securities evidencing interests in ARM
Loans, by changes in the Net Mortgage Rates on the ARM Loans. See 'Maturity and
Prepayment Considerations' below. The yield on the Securities also will be
effected by liquidations of Mortgage Loans following Mortgagor defaults and by
purchases of Mortgage Loans required by the Pooling and Servicing Agreement in
the event of breaches of representations made in respect of such Mortgage Loans
by the Sponsor, the Originators, the Master Servicer and others, or repurchases
due to conversions of ARM Loans to a fixed interest rate. See 'Mortgage Loan
Program--Representations by Originators' and 'Descriptions of the
Securities--Assignment of Mortgage Loans' above. In general, if a class of
Securities is purchased at initial issuance at a premium and payments of
principal on the related Mortgage Loans occur at a rate faster than anticipated
at the time of purchase, the purchaser's actual yield to maturity will be lower
than that assumed at the time of purchase. Conversely, if a class of Securities
is purchased at initial issuance at a discount and payments of principal on the
related Mortgage Loans occur at a rate slower than that assumed at the time of
purchase, the purchaser's actual yield to maturity will be lower than that
originally anticipated. The effect of principal prepayments, liquidations and
purchases on yield will be particularly
 
                                       63
<PAGE>
significant in the case of a series of Securities having a class entitled to
payments of interest only or to payments of interest that are disproportionately
high relative to the principal payments to which such class is entitled. Such a
class likely will be sold at a substantial premium to its principal balance, if
any, and any faster than anticipated rate of prepayments will adversely affect
the yield to holders thereof. In certain circumstances, rapid prepayments may
result in the failure of such holders to recoup their original investment. In
addition, the yield to maturity on certain other types of classes of Securities,
including Accrual Securities or certain other classes in a series including more
than one class of Securities, may be relatively more sensitive to the rate of
prepayment on the related Mortgage Loans than other classes of Securities.
 
     The timing of changes in the rate of principal payments on or repurchases
of the Mortgage Loans may significantly affect an investor's actual yield to
maturity, even if the average rate of principal payments experienced over time
is consistent with an investor's expectation. In general, the earlier a
prepayment of principal on the underlying Mortgage Loans or a repurchase
thereof, the greater will be the effect on an investor's yield to maturity. As a
result, the effect on an investor's yield of principal payments and repurchases
occurring at a rate higher (or lower) than the rate anticipated by the investor
during the period immediately following the issuance of a series of Securities
would not be fully offset by a subsequent like reduction (or increase) in the
rate of principal payments.
 
     The Mortgage Rates on certain ARM Loans subject to negative amortization
adjust monthly and their amortization schedules adjust less frequently. During a
period of rising interest rates as well as immediately after origination
(initial Mortgage Rates are generally lower than the sum of the Indices
applicable at origination and the related Note Margins) the amount of interest
accruing on the principal balance of such Mortgage Loans may exceed the amount

of the minimum scheduled monthly payment thereon. As a result, a portion of the
accrued interest on negatively amortizing Mortgage Loans may become Deferred
Interest that will be added to the principal balance thereof and will bear
interest at the applicable Mortgage Rate. The addition of any such Deferred
Interest to the principal balance will lengthen the weighted average life of the
Securities evidencing interests in such Mortgage Loans and may adversely affect
yield to holders thereof depending upon the price at which such Securities were
purchased. In addition, with respect to certain ARM Loans subject to negative
amortization, during a period of declining interest rates, it might be expected
that each minimum scheduled monthly payment on such a Mortgage Loan would exceed
the amount of scheduled principal and accrued interest on the principal balance
thereof, and since such excess will be applied to reduce such principal balance,
the weighted average life of such Securities will be reduced and may adversely
affect yield to holders thereof depending upon the price at which such
Securities were purchased.
 
     For each Mortgage Pool, if all necessary advances are made and if there is
no unrecoverable loss on any Mortgage Loan and if the related Credit Enhancer is
not in default under its obligations or other Credit Enhancement has not been
exhausted, the net effect of each distribution respecting interest will be to
pass-through to each holder of a class of Securities entitled to payments of
interest an amount which is equal to one month's interest (or, in the case of
quarterly-pay Securities, three month's interest or, in the case of semi-
annually-pay Securities, six months' interest) at the applicable Pass-Through
Rate on such class' principal balance or notional balance, as adjusted downward
to reflect any decrease in interest caused by any principal prepayments and the
addition of any Deferred Interest to the principal balance of any Mortgage Loan.
'Description of the Securities--Principal and Interest on the Securities.'
 
     With respect to certain of the ARM Loans, the Mortgage Rate at origination
may be below the rate that would result if the index and margin relating thereto
were applied at origination. Under the Sponsor's underwriting standards, the
Mortgagor under each Mortgage Loan will be qualified on the basis of the
Mortgage Rate in effect at origination. The repayment of any such Mortgage Loan
may thus be dependent on the ability of the Mortgagor to make larger level
monthly payments following the adjustment of the Mortgage Rate.
 
                     MATURITY AND PREPAYMENT CONSIDERATIONS
 
     As indicated above under 'The Mortgage Pools,' the original terms to
maturity of the Mortgage Loans in a given Mortgage Pool will vary depending upon
the type of Mortgage Loans included in such Mortgage Pool. The Prospectus
Supplement for a series of Securities will contain information with respect to
the types and maturities of the Mortgage Loans in the related Mortgage Pool.
Unless otherwise specified in the related Prospectus
 
                                       64
<PAGE>
Supplement, all of the Mortgage Loans may be prepaid without penalty in full or
in part at any time. The prepayment experience with respect to the Mortgage
Loans in a Mortgage Pool will affect the maturity, average life and yield of the
related series of Securities.
 
     With respect to Balloon Loans, payment of the Balloon Amount (which, based

on the amortization schedule of such Mortgage Loans, may be a substantial
amount) will generally depend on the Mortgagor's ability to obtain refinancing
of such Mortgage Loan or to sell the Mortgaged Property prior to the maturity of
the Balloon Loan. The ability to obtain refinancing will depend on a number of
factors prevailing at the time refinancing or sale is required, including,
without limitation, real estate values, the Mortgagor's financial situation,
prevailing mortgage loan interest rates, the Mortgagor's equity in the related
Mortgaged Property, tax laws and prevailing general economic conditions. Unless
otherwise specified in the related Prospectus Supplement, neither the Sponsor,
the Master Servicer, nor any of their affiliates will be obligated to refinance
or repurchase any Mortgage Loan or to sell the Mortgaged Property.
 
     A number of factors, including homeowner mobility, economic conditions,
enforceability of due-on-sale clauses, mortgage market interest rates and the
availability of mortgage funds, affect prepayment experience. Unless otherwise
specified in the related Prospectus Supplement, the Mortgage Loans will
generally contain due-on-sale provisions permitting the mortgagee to accelerate
the maturity of the Mortgage Loan upon sale or certain transfers by the
Mortgagor of the underlying Mortgaged Property. Unless the related Prospectus
Supplement indicates otherwise, the Master Servicer will generally enforce any
due-on-sale clause to the extent it has knowledge of the conveyance or proposed
conveyance of the underlying Mortgaged Property and it is entitled to do so
under applicable law; provided, however, that the Master Servicer will not take
any action in relation to the enforcement of any due-on-sale provision which
would adversely affect or jeopardize coverage under any applicable insurance
policy. Certain ARM Loans may be assumable under certain conditions if the
proposed transferee of the related Mortgaged Property establishes its ability to
repay the Mortgage Loan and, in the reasonable judgment of the Master Servicer
or the related Sub-Servicer, the security for the ARM Loan would not be impaired
or might be improved by the assumption. The extent to which ARM Loans are
assumed by purchasers of the Mortgaged Properties rather than prepaid by the
related Mortgagors in connection with the sales of the Mortgaged Properties will
affect the weighted average life of the related series of Securities. See
'Description of the Securities--Collection and Other Servicing Procedures' and
'Certain Legal Aspects of the Mortgage Loans and Related Matters--Enforceability
of Certain Provisions' for a description of certain provisions of the Pooling
and Servicing Agreement and certain legal developments that may affect the
prepayment experience on the Mortgage Loans.
 
     There can be no assurance as to the rate of prepayment of the Mortgage
Loans. The Sponsor is not aware of any reliable, publicly available statistics
relating to the principal prepayment experience of diverse portfolios of
mortgage loans such as the Mortgage Loans over an extended period of time. All
statistics known to the Sponsor that have been compiled with respect to
prepayment experience on mortgage loans indicates that while some mortgage loans
may remain outstanding until their stated maturities, a substantial number will
be paid prior to their respective stated maturities.
 
     Although the Mortgage Rates on ARM Loans will be subject to periodic
adjustments, such adjustments will, unless otherwise specified in the related
Prospectus Supplement, (i) not increase or decrease such Mortgage Rates by more
than a fixed percentage amount on each adjustment date, (ii) not increase such
Mortgage Rates over a fixed percentage amount during the life of any ARM Loan
and (iii) be based on an index (which may not rise and fall consistently with

mortgage interest rates) plus the related Note Margin (which may be different
from margins being used at the time for newly originated adjustable rate
mortgage loans). As a result, the Mortgage Rates on the ARM Loans in a Mortgage
Pool at any time may not equal the prevailing rates for similar, newly
originated adjustable rate mortgage loans. In certain rate environments, the
prevailing rates on fixed-rate mortgage loans may be sufficiently low in
relation to the then-current Mortgage Rates on ARM Loans that the rate of
prepayment may increase as a result of refinancings. There can be no certainty
as to the rate of prepayments on the Mortgage Loans during any period or over
the life of any series of Securities.
 
     As may be described in the related Prospectus Supplement, the related
Pooling and Servicing Agreement may provide that all or a portion of the
principal collected on or with respect to the related Mortgage Loans may be
applied by the related Trustee to the acquisition of additional Mortgage Loans
during a specified period (rather
 
                                       65
<PAGE>
than used to fund payments of principal to Securityholders during such period)
with the result that the related securities possess an interest-only period,
also commonly referred to as a revolving period, which will be followed by an
amortization period. Any such interest-only or revolving period may, upon the
occurrence of certain events to be described in the related Prospectus
Supplement, terminate prior to the end of the specified period and result in the
earlier than expected amortization of the related Securities.
 
     In addition, and as may be described in the related Prospectus Supplement,
the related Pooling and Servicing Agreement may provide that all or a portion of
such collected principal may be retained by the Trustee (and held in certain
temporary investments, including Mortgage Loans) for a specified period prior to
being used to fund payments of principal to Securityholders.
 
     The result of such retention and temporary investment by the Trustee of
such principal would be to slow the amortization rate of the related Securities
relative to the amortization rate of the related Mortgage Loans, or to attempt
to match the amortization rate of the related Securities to an amortization
schedule established at the time such Securities are issued. Any such feature
applicable to any Securities may terminate upon the occurrence of events to be
described in the related Prospectus Supplement, resulting in the current funding
of principal payments to the related Securityholders and an acceleration of the
amortization of such Securities.
 
     Under certain circumstances, the Master Servicer, the Sponsor or, if
specified in the related Prospectus Supplement, the holders of the REMIC
Residual Securities or the Credit Enhancer may have the option to purchase the
Mortgage Loans in a Trust Estate. See 'The Pooling and Servicing
Agreement--Termination; Retirement of Securities.'
 
          CERTAIN LEGAL ASPECTS OF MORTGAGE LOANS AND RELATED MATTERS
 
     The following discussion contains summaries of certain legal aspects of
mortgage loans that are general in nature. Because such legal aspects are
governed in part by applicable state law (which laws may differ substantially),

the summaries do not purport to be complete nor to reflect the laws of any
particular state nor to encompass the laws of all states in which the Mortgaged
Properties may be situated. The summaries are qualified in their entirety by
reference to the applicable federal and state laws governing the Mortgage Loans.
 
GENERAL
 
     The Mortgage Loans will be secured by either deeds of trust or mortgages,
depending upon the prevailing practice in the state in which the Mortgaged
Property subject to a Mortgage Loan is located. In some states, a mortgage
creates a lien upon the real property encumbered by the mortgage. In other
states, the mortgage conveys legal title to the property to the mortgagee
subject to a condition subsequent (i.e., the payment of the indebtedness secured
thereby). The mortgage is not prior to the lien for real estate taxes and
assessments and other charges imposed under governmental police powers. Priority
between mortgages depends on their terms in some cases or on the terms of
separate subordination or intercreditor agreements, and generally on the order
of recordation of the mortgage in the appropriate recording office. There are
two parties to a mortgage, the mortgagor, who is the borrower and homeowner, 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 is the beneficiary;
at origination of a mortgage loan, the borrower executes a separate undertaking
to make payments on the mortgage note. Although a deed of trust is similar to a
mortgage, a deed of trust has three parties; the borrower-homeowner called the
trustor (similar to a mortgagor), a lender (similar to a mortgagee) called the
beneficiary, and a third-party grantee called the trustee. Under a deed of
trust, the borrower grants the property, irrevocably until the debt is paid, in
trust, generally with a power of sale, to the trustee to secure payment of the
obligation. The trustee's authority under a deed of trust and the mortgagee's
authority under a mortgage are governed by law, the express provisions of the
deed of trust or mortgage, and, in some cases, the directions of the
beneficiary.
 
                                       66
<PAGE>
COOPERATIVE LOANS
 
     If specified in the Prospectus Supplement relating to a series of
Securities, the Mortgage Loans also may consist of Cooperative Loans evidenced
by Cooperative Notes secured by security interests in shares issued by
cooperatives, which are private corporations that are entitled to be treated as
housing cooperatives under federal tax law, and in the related proprietary
leases or occupancy agreements granting exclusive rights to occupy specific
dwelling units in the cooperatives' buildings. The security agreement will
create a lien upon, or grant a title interest in, the property which it covers,
the priority of which will depend on the terms of the particular security
agreement as well as the order of recordation of the agreement in the
appropriate recording office. Such a lien or title interest is not prior to the
lien for real estate taxes and assessments and other charges imposed under
governmental police powers.
 
     Each cooperative owns in fee or has a leasehold interest in all the real

property and owns in fee or leases the building and all separate dwelling units
therein. The cooperative is directly responsible for property management and, in
most cases, payment of real estate taxes, other governmental impositions and
hazard and liability insurance. If there is a blanket mortgage or mortgages on
the cooperative apartment building or underlying land, as is generally the case,
or an underlying lease of the land, as is the case in some instances, the
cooperative, as property mortgagor, or lessee, as the case may be, also is
responsible for meeting these mortgage or rental obligations. A blanket mortgage
is ordinarily incurred by the cooperative in connection with either the
construction or purchase of the cooperative's apartment building or the
obtaining of capital by the cooperative. The interest of the occupant under
proprietary leases or occupancy agreements as to which that cooperative is the
landlord generally is subordinate to the interest of the holder of a blanket
mortgage and to the interest of the holder of a land lease. If the cooperative
is unable to meet the payment obligations (i) arising under a blanket mortgage,
the mortgagee holding a blanket mortgage could foreclose on that mortgage and
terminate all subordinate proprietary leases and occupancy agreements or (ii)
arising under its land lease, the holder of the landlord's interest under the
land lease could terminate it and all subordinate proprietary leases and
occupancy agreements. Also, a blanket mortgage on a cooperative may provide
financing in the form of a mortgage that does not fully amortize, with a
significant portion of principal being due in one final payment at maturity. The
inability of the cooperative to refinance a mortgage and its consequent
inability to make such final payment could lead to foreclosure by the mortgagee.
Similarly, a land lease has an expiration date and the inability of the
cooperative to extend its term or, in the alternative, to purchase the land
could lead to termination of the cooperative's interest in the property and
termination of all proprietary leases and occupancy agreements. In either event,
a foreclosure by the holder of a blanket mortgage or the termination of the
underlying lease could eliminate or significantly diminish the value of any
collateral held by the lender who financed the purchase by an individual
tenant-stockholder of cooperative shares or, in the case of the Mortgage Loans,
the collateral securing the Cooperative Loans.
 
     The cooperative is owned by tenant-stockholders who, through ownership of
stock or shares in the corporation, receive proprietary leases or occupancy
agreements that confer exclusive rights to occupy specific units. Generally, a
tenant-stockholder of a cooperative must make a monthly payment to the
cooperative representing such tenant-stockholder's pro rata share of the
cooperative's payments for its blanket mortgage, real property taxes,
maintenance expenses and other capital or ordinary expenses. An ownership
interest in a cooperative and accompanying occupancy rights are financed through
a cooperative share loan evidenced by a promissory note and secured by an
assignment of and a security interest in the occupancy agreement or proprietary
lease and a security interest in the related cooperative shares. The lender
generally takes possession of the share certificate and a counterpart of the
proprietary lease or occupancy agreement and a financing statement covering the
proprietary lease or occupancy agreement and the cooperative shares is filed in
the appropriate state and local offices to perfect the lender's interest in its
collateral. Subject to the limitations discussed below, upon default of the
tenant-stockholder, the lender may sue for judgment on the promissory note,
dispose of the collateral at a public or private sale or otherwise proceed
against the collateral or tenant-stockholder as an individual as provided in the
security agreement covering the assignment of the proprietary lease or occupancy

agreement and the pledge of cooperative shares. See 'Foreclosure on Shares of
Cooperatives' below.

FORECLOSURE
 
     Foreclosure of a deed of trust is generally accomplished by a non-judicial
trustee's sale (private sale) under a specific provision in the deed of trust
and state laws which authorize the trustee to sell the property upon any default
by the borrower under the terms of the note or deed of trust. Beside the
nonjudicial remedy, a deed of trust may be judicially foreclosed. In addition to
any notice requirements contained in a deed of trust, in some states, the
trustee must record a notice of default and within a certain period of time send
a copy to the borrower trustor and to any person who has recorded a request for
a copy of notice of default and notice of sale. In addition, the trustee must
provide notice in some states to any other individual having an interest of
record in the real property, including any junior lienholders. If the deed of
trust is not reinstated within a specified period, a notice of sale must be
posted in a public place and, in most states, published for a specific period of
time in one or more local 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 real property.
 
     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 may occasionally result from difficulties in locating
necessary parties. Judicial foreclosure proceedings are often not contested by
any of the applicable parties. If the mortgagee's right to foreclose is
contested, the legal proceedings necessary to resolve the issue can be
time-consuming.
 
     In some states, the borrower-trustor has the right to reinstate the loan at
any time following default until shortly before the trustee's sale. In general,
in such states, the borrower, or any other person having a junior encumbrance on
the real estate, may, during a reinstatement period, cure the default by paying
the entire amount in arrears plus the costs and expenses incurred in enforcing
the obligation.
 
     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 a potential buyer at the sale would
have in determining the exact status of title and because the physical condition
of the property may have deteriorated during the foreclosure proceedings, it is
uncommon for a third party to purchase the property at a foreclosure sale unless
there is a great deal of economic incentive for the new purchaser to purchase
the subject property at the sale. Rather, it is common for the lender to
purchase the property from the trustee or referee for a credit bid less than or
equal to the unpaid principal amount of the mortgage or deed of trust, accrued
and unpaid interest and the expense of foreclosure. Generally, state law
controls the amount of foreclosure costs and expenses, including attorneys'
fees, which may be recovered by a lender. Thereafter, subject to the right of
the borrower in some states to remain in possession during the redemption

period, the lender will assume the burdens of ownership, including obtaining
hazard insurance and making such repairs at its own expense as are necessary to
render the property suitable for sale. The lender will commonly obtain the
services of a real estate broker and pay the broker's commission in connection
with the sale of the property. Depending upon market conditions, the ultimate
proceeds of the sale of the property may not equal the lender's investment in
the property and, in some states, the lender may be entitled to a deficiency
judgment. Any loss may be reduced by the receipt of any mortgage insurance
proceeds.
 
FORECLOSURE ON SHARES OF COOPERATIVES
 
     The cooperative shares and proprietary lease or occupancy agreement owned
by the tenant-stockholder and pledged to the lender are, in almost all cases,
subject to restrictions on transfer as set forth in the cooperative's
certificate of incorporation and by-laws, as well as in the proprietary lease or
occupancy agreement. The proprietary lease or occupancy agreement, even while
pledged, may be cancelled by the cooperative for failure by the tenant
stockholder to pay rent or other obligations or charges owed by such
tenant-stockholder, including mechanics' liens against the cooperative apartment
building incurred by such tenant-stockholder. Commonly, rent and other
obligations and charges arising under a proprietary lease or occupancy agreement
that are owed to the cooperative are made liens upon the shares to which the
proprietary lease or occupancy agreement relates. In addition, the proprietary
lease or occupancy agreement generally permits the cooperative to terminate such
lease or agreement in the event the borrower defaults in the performance of
covenants thereunder. Typically, the lender and the cooperative enter into a
recognition agreement that, together with any lender protection provisions
contained in the proprietary lease, establishes the rights and obligations of
both parties in the event of a default by
 
                                       68
<PAGE>
the tenant-stockholder on its obligations under the proprietary lease or
occupancy agreement. A default by the tenant-stockholder under the proprietary
lease or occupancy agreement usually will constitute a default under the
security agreement between the lender and the tenant-stockholder.
 
     The recognition agreement generally provides that, in the event that the
tenant-stockholder has defaulted under the proprietary lease or occupancy
agreement, the cooperative will take no action to terminate such lease or
agreement until the lender has been provided with notice of and an opportunity
to cure the default. The recognition agreement typically provides that if the
proprietary lease or occupancy agreement is terminated, the cooperative will
recognize the lender's lien against proceeds from a sale of the cooperative
apartment, subject, however, to the cooperative's right to sums due under such
proprietary lease or occupancy agreement or sums that have become liens on the
shares relating to the proprietary lease or occupancy agreement. The total
amount owed to the cooperative by the tenant-stockholder, which the lender
generally cannot restrict and does not monitor, could reduce the amount realized
upon a sale of the collateral below the outstanding principal balance of the
Cooperative Loan and accrued and unpaid interest thereon.
 
     Recognition agreements generally also provide that in the event of a

foreclosure on a Cooperative Loan, the lender must obtain the approval or
consent of the cooperative as required by the proprietary lease before
transferring the cooperative shares or assigning the proprietary lease.
Generally, the lender is not limited in any rights it may have to dispossess the
tenant-stockholder.
 
     In New York, foreclosure on the cooperative shares is accomplished by
public sale in accordance with the provisions of Article 9 of the UCC and the
security agreement relating to those shares. Article 9 of the UCC requires that
a sale be conducted in a 'commercially reasonable' manner. Whether a sale has
been conducted in a 'commercially reasonable' manner will depend on the facts in
each case. In determining commercial reasonableness, a court will look to the
notice given the debtor and the method, manner, time, place and terms of the
sale and the sale price. Generally, a sale conducted according to the usual
practice of banks selling similar collateral will be considered reasonably
conducted.
 
     Article 9 of the UCC provides that the proceeds of the sale will be applied
first to pay the costs and expenses of the sale and then to satisfy the
indebtedness secured by the lender's security interest. The recognition
agreement, however, generally provides that the lender's right to reimbursement
is subject to the right of the cooperative corporation to receive sums due under
the proprietary lease or occupancy agreement. If there are proceeds remaining,
the lender must account to the tenant-stockholder for the surplus. Conversely,
if a portion of the indebtedness remains unpaid, the tenant-stockholder is
generally responsible for the deficiency. See 'Anti-Deficiency Legislation and
Other Limitations on Lenders' below.
 
RIGHTS OF REDEMPTION
 
     In some states, after sale pursuant to a deed of trust or foreclosure of a
mortgage, the borrower and foreclosed junior lienors or other parties are given
a statutory period in which to redeem the property from 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 rights of
redemption would defeat the title of any purchaser subsequent to foreclosure or
sale under a deed of trust. Consequently, the practical effect of the redemption
right is to force the lender to maintain the property and pay the expenses of
ownership until the redemption period has expired. In some states, there is no
right to redeem property after a trustee's sale under a deed of trust.
 
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, including California, statutes limit the right of the beneficiary or
mortgagee to obtain a deficiency judgment against the borrower following
foreclosure. A deficiency judgment is a personal judgment against the former
borrower equal in most cases to the difference between the amount due to the
lender and the net amount realized upon the public sale of the real property. In
the case of a Mortgage Loan secured by a property owned by a trust where the

Mortgage Note is executed on behalf
 
                                       69
<PAGE>
of the trust, a deficiency judgment against the trust following foreclosure or
sale under a deed of trust, even if obtainable under applicable law, may be of
little value to the mortgagee or beneficiary if there are no trust assets
against which such deficiency judgment may be executed. 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, in
those states permitting such election, is that lenders will usually proceed
against the security first rather than bringing a personal action against the
borrower. Finally, in certain other states, statutory provisions limit any
deficiency judgment against the former borrower following a foreclosure to the
excess of the outstanding debt over the fair value of the property at the time
of the public sale. The purpose of these statutes is generally to prevent a
beneficiary or mortgagee from obtaining a large deficiency judgment against the
former borrower as a result of low or no bids at the judicial sale.
 
     In addition to laws limiting or prohibiting deficiency judgments, numerous
other 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 collateral or enforce
a deficiency judgment. For example, with respect to federal bankruptcy law, a
court with federal bankruptcy jurisdiction may permit a debtor through his or
her Chapter 11 or Chapter 13 rehabilitative plan to cure a monetary default in
respect of a mortgage loan on a debtor's residence by paying arrearages within a
reasonable time period and reinstating the original mortgage loan payment
schedule even though the lender accelerated the mortgage loan and final judgment
of foreclosure had been entered in state court (provided no sale of the
residence had yet occurred) prior to the filing of the debtor's petition. Some
courts with federal bankruptcy jurisdiction have approved plans, based on the
particular facts of the reorganization case, that effected the curing of a
mortgage loan default by paying arrearages over a number of years.
 
     Courts with federal bankruptcy jurisdiction also have indicated that the
terms of a mortgage loan secured by property of the debtor may be modified.
These courts have allowed modifications that include reducing the amount of each
monthly payment, changing the rate of interest, altering the repayment schedule,
forgiving all or a portion of the debt 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.
 
     Certain states have imposed general equitable principles upon judicial
foreclosure. These equitable principles are generally designed to relieve the
borrower from the legal effect of the borrower's default under the related 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 for the borrower's default and the likelihood
that the borrower will be able to reinstate the loan. In some cases, lenders
have been required to reinstate loans or recast payment schedules in order to
accommodate borrowers who are suffering from temporary financial disabilities.
In other cases, such courts have limited the right of the lender to foreclose if
the default under the loan is not monetary, such as the borrower failing to
adequately maintain the property or the borrower executing a second deed of
trust affecting the property.
 
     Certain tax liens arising under the Internal Revenue Code of 1986, as
amended, may in certain circumstances provide priority over the lien of a
mortgage or deed of trust. In addition, substantive requirements are imposed
upon mortgage lenders in connection with the origination and the servicing of
mortgage loans by numerous federal and some state consumer protection laws.
These laws include, by example, 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 the California Fair Debt
Collection Practices Act. These laws and regulations impose specific statutory
liabilities upon lenders who originate mortgage loans and fail to comply with
the provisions of the law. In some cases, this liability may affect assignees of
the mortgage loans.
 
ENVIRONMENTAL LEGISLATION
 
     Certain states impose a statutory lien for associated costs on property
that is the subject of a cleanup action by the state on account of hazardous
wastes or hazardous substances released or disposed of on the property. Such a
lien generally will have priority over all subsequent liens on the property and,
in certain of these states,
 
                                       70
<PAGE>
will have priority over prior recorded liens including the lien of a mortgage.
In some states, however, such a lien will not have priority over prior recorded
liens of a deed of trust. In addition, under federal environmental legislation
and under state law in a number of states, a secured party which takes a deed in
lieu of foreclosure or acquires a mortgaged property at a foreclosure sale or
assumes active control over the operation or management of a property so as to
be deemed an 'owner' or 'operator' of the property may be liable for the costs
of cleaning up a contaminated site. Although such costs could be substantial, it
is unclear whether they would be imposed on a lender (such as a Trust Estate)
secured by residential real property. In the event that title to a Mortgaged
Property securing a Mortgage Loan in a Trust Estate was acquired by the Trust
and cleanup costs were incurred in respect of the Mortgaged Property, the
holders of the related series of Securities might realize a loss if such costs
were required to be paid by the Trust.
 
ENFORCEABILITY OF CERTAIN PROVISIONS
 
     Unless the Prospectus Supplement indicates otherwise, generally all of the
Mortgage Loans contain due-on-sale clauses. These clauses permit the lender to
accelerate the maturity of the loan if the borrower sells, transfers or conveys
the property. The enforceability of these clauses has been the subject of

legislation or litigation in many states including California, and in some cases
the enforceability of these clauses was limited or denied. However, 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 limited exceptions. 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.
 
     The Garn-St. Germain Act also sets forth nine specific instances in which a
mortgage lender covered by the Garn-St. Germain Act may not exercise a
due-on-sale clause, notwithstanding the fact that a transfer of the property may
have occurred. These include intra-family transfers, certain transfers by
operation of law, leases of fewer than three years and the creation of a junior
encumbrance. Regulations promulgated under the Garn-St. Germain Act also
prohibit the imposition of a prepayment penalty upon the acceleration of a loan
pursuant to a due-on-sale clause.
 
     The inability to enforce a due-on-sale clause may result in a mortgage loan
bearing an interest rate below the current market rate being assumed by a new
home buyer rather than being paid off, that may have an impact upon the average
life of the Mortgage Loans and the number of Mortgage Loans that may be
outstanding until maturity.
 
     Upon foreclosure, courts have imposed general equitable principles. These
equitable principles generally are 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 for 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
the lender to foreclose if the default under the mortgage instrument is not
monetary, such as the borrower failing to adequately maintain the property or
the borrower executing a second mortgage or deed of trust 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 deeds of trust or mortgages receive
notices in addition to the statutorily prescribed minimum. For the most part,
these cases have upheld the notice provisions as being reasonable or have found
that the sale by a trustee under a deed of trust, or under a mortgage having a
power of sale, does not involve sufficient state action to afford constitutional
protections to the borrower.
 
CERTAIN PROVISIONS OF CALIFORNIA DEEDS OF TRUST
 
     Most institutional lenders in California use a form of deed of trust that
confers on the beneficiary the right both to receive all proceeds collected
under any hazard insurance policy and all awards made in connection with any
condemnation proceedings, and to apply such proceeds and awards to any
indebtedness secured by the deed of trust, in such order as the beneficiary may

determine, provided, however, that California law prohibits the beneficiary from
applying insurance and condemnation proceeds to the indebtedness secured by the
deed of trust
 
                                       71
<PAGE>
unless the beneficiary's security has been impaired by the casualty or
condemnation, and, if such security has been impaired, permits such proceeds to
be so applied only to the extent of such impairment. 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, and, as a result thereof,
the beneficiary's security is impaired, the beneficiary under the underlying
first deed of trust 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
first deed of trust. Proceeds in excess of the amount of indebtedness secured by
a first deed of trust will, in most cases, be applied to the indebtedness of a
junior deed of trust.
 
     Another provision typically found in the forms of deed of trust used by
most institutional lenders in California obligates the trustor to pay before
delinquency all taxes and assessments on the property and, when due, all
encumbrances, charges and liens on the property which appear prior to the 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 beneficiary under the deed of trust. Upon a failure of the
trustor to perform any of these obligations, the beneficiary is given the right
under the deed of trust to perform the obligation itself, at its election, with
the trustor agreeing to reimburse the beneficiary for any sums expended by the
beneficiary on behalf of the trustor. All sums so expended by the beneficiary
become part of the indebtedness secured by the deed of trust.
 
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. A similar federal statute
was in effect with respect to mortgage loans made during the first three months
of 1980. The Office of Thrift Supervision is authorized to issue rules and
regulations and to publish interpretations governing implementation of Title V.
The statute authorized any state to reimpose interest rate limits by adopting,
before April 1, 1983, a law or constitutional provision which expressly rejects
application of the federal law. 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. Certain
states have taken action to reimpose interest rate limits or to limit discount
points or other charges.
 
     As indicated above under 'Mortgage Loan Program--Representations by
Originators,' each Originator of a Mortgage Loan will have represented that such
Mortgage Loan was originated in compliance with then applicable state laws,
including usury laws, in all material respects. However, the Mortgage Rates on

the Mortgage Loans will be subject to applicable usury laws as in effect from
time to time.
 
ALTERNATIVE MORTGAGE INSTRUMENTS
 
     Alternative mortgage instruments, including ARM Loans and early ownership
mortgage loans, originated by non-federally chartered lenders have historically
been subjected to a variety of restrictions. Such restrictions differed from
state to state, resulting in difficulties in determining whether a particular
alternative mortgage instrument originated by a state-chartered lender was in
compliance with applicable law. These difficulties were alleviated substantially
as a result of the enactment of Title VIII of the Garn-St. Germain Act ('Title
VIII'). Title VIII provides that: notwithstanding any state law to the contrary,
state-chartered banks may originate alternative mortgage instruments in
accordance with regulations promulgated by the Comptroller of the Currency with
respect to origination of alternative mortgage instruments by national banks;
state-chartered credit unions may originate alternative mortgage instruments in
accordance with regulations promulgated by the National Credit Union
Administration with respect to origination of alternative mortgage instruments
by federal credit unions; and all other non-federally chartered housing
creditors, including state-chartered savings and loan associations,
state-chartered savings banks and mutual savings banks and mortgage banking
companies, may originate alternative mortgage instruments in accordance with the
regulations promulgated by the Federal Home Loan Bank Board, predecessor to the
Office of Thrift Supervision, with respect to origination of alternative
mortgage instruments by federal savings and loan associations. Title VIII
provides that any state may reject applicability of the provisions of Title VIII
by adopting, prior to October 15, 1985, a law or constitutional provision
expressly rejecting the applicability of such provisions. Certain states have
taken such action.
 
                                       72
<PAGE>
SOLDIERS' AND SAILORS' CIVIL RELIEF ACT OF 1940
 
     Under the terms of the Soldiers' and Sailors' Civil Relief Act of 1940, as
amended (the 'Relief Act'), a Mortgagor who enters military service after the
origination of such Mortgagor's Mortgage Loan (including a Mortgagor who was in
reserve status and is called to active duty after origination of the Mortgage
Loan), may not be charged interest (including fees and charges) above an annual
rate of 6% during the period of such Mortgagor's active duty status, unless a
court orders otherwise upon application of the lender. The Relief Act applies to
Mortgagors who are members of the Army, Navy, Air Force, Marines, National
Guard, Reserves, Coast Guard, and officers of the U.S. Public Health Service
assigned to duty with the military. Because the Relief Act applies to Mortgagors
who enter military service (including reservists who are called to active duty)
after origination of the related Mortgage Loan, no information can be provided
as to the number of loans that may be affected by the Relief Act. Application of
the Relief Act would adversely affect, for an indeterminate period of time, the
ability of the Master Servicer to collect full amounts of interest on certain of
the Mortgage Loans. Any shortfall in interest collections resulting from the
application of the Relief Act or similar legislation or regulations, which would
not be recoverable from the related Mortgage Loans, would result in a reduction
of the amounts distributable to the holders of the related Securities, and would

not be covered by advances, any Letter of Credit or any other form of Credit
Enhancement provided in connection with the related series of Securities. In
addition, the Relief Act imposes limitations that would impair the ability of
the Master Servicer to foreclose on an affected Mortgage Loan during the
Mortgagor's period of active duty status, and, under certain circumstances,
during an additional three month period thereafter. Thus, in the event that the
Relief Act or similar legislation or regulations apply to any Mortgage Loan
which goes into default, there may be delays in payment and losses on the
related Securities in connection therewith. Any other interest shortfalls,
deferrals or forgiveness of payments on the Mortgage Loans resulting from
similar legislation or regulations may result in delays in payments or losses to
Securityholders of the related series.
 
                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
GENERAL
 
     The following is a general discussion of the material anticipated federal
income tax consequences to investors of the purchase, ownership and disposition
of the Securities offered hereby. The discussion is based upon laws,
regulations, rulings and decisions now in effect, all of which are subject to
change. The discussion below does not purport to deal with all federal tax
consequences applicable to all categories of investors, some of which may be
subject to special rules. Investors should consult their own tax advisors in
determining the federal, state, local and any other tax consequences to them of
the purchase, ownership and disposition of the Securities. For purposes of this
discussion, references to a 'Securityholder' or a 'Holder' are to the beneficial
owner of a Security.
 
     The following discussion addresses securities of three general types: (i)
securities ('Grantor Trust Securities') representing interests in a Trust Estate
(a 'Grantor Trust Estate') which the Sponsor will covenant not to elect to have
treated as a real estate mortgage investment conduit (REMIC); (ii) securities
('REMIC Securities') representing interests in a Trust Estate, or a portion
thereof, which the Sponsor will covenant to elect to have treated as a REMIC
under sections 860A through 860G of the Internal Revenue Code of 1986, as
amended (the 'Code'); and (iii) securities ('Debt Securities') that are intended
to be treated for federal income tax purposes as indebtedness secured by the
underlying Mortgage Loans. This Prospectus does not address the tax treatment of
partnership interests or interests in a FASIT. Such a discussion will be set
forth in the related Prospectus Supplement for any Trust issuing Securities
characterized as partnership interests or interests in a FASIT. The Prospectus
Supplement for each series of Securities will indicate whether a REMIC or FASIT
election (or elections) will be made for the related Trust Estate and, if a
REMIC or FASIT election is to be made, will identify all 'regular interests' and
'residual interests' in the REMIC or all 'regular interests,' 'high-yield
interests' or 'ownership interest' in the FASIT. Pursuant to the Small Business
Job Protection Act of 1996, enacted on August 20, 1996 (the '1996 Act'), a FASIT
election can be made on or after September 1, 1997.
 
GRANTOR TRUST SECURITIES
 
     With respect to each series of Grantor Trust Securities, Dewey Ballantine,
special tax counsel to the Sponsor, will deliver its opinion to the Sponsor that

(unless otherwise limited in the related Prospectus Supplement) the related
Grantor Trust Estate will be classified as a grantor trust and not as a
partnership or an
 
                                       73
<PAGE>
association taxable as a corporation. Accordingly, each Holder of a Grantor
Trust Security will generally be treated as the owner of an interest in the
Mortgage Loans included in the Grant or Trust Estate.
 
     For purposes of the following discussion, a Grantor Trust Security
representing an undivided equitable ownership interest in the principal of the
Mortgage Loans constituting the related Grantor Trust Estate, together with
interest thereon at a pass-through rate, will be referred to as a 'Grantor Trust
Fractional Interest Security.' A Grantor Trust Security representing ownership
of all or a portion of the difference between interest paid on the Mortgage
Loans constituting the related Grantor Trust Estate and interest paid to the
Holders of Grantor Trust Fractional Interest Securities issued with respect to
such Grantor Trust Estate will be referred to as a 'Grantor Trust Strip
Security.'
 
  Special Tax Attributes
 
     Unless otherwise disclosed in a related Prospectus Supplement, Dewey
Ballantine, special tax counsel to the Sponsor, will deliver its opinion to the
Sponsor that (a) Grantor Trust Fractional Interest Securities will represent
interests in (i) 'loans . . . secured by an interest in real property' within
the meaning of section 7701(a)(19)(C)(v) of the Code; and (ii) 'obligations
(including any participation or certificate of beneficial ownership therein)
which . . . are principally secured by an interest in real property' within the
meaning of section 860G(a)(3)(A) of the Code; and (b) interest on Grantor Trust
Fractional Interest Securities will be considered '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. In addition, the Grantor Trust
Strip Securities will be 'obligations (including any participation or
certificate of beneficial ownership therein) . . . principally secured by an
interest in real property' within the meaning of section 860G(a)(3)(A) of the
Code.
 
     The 1996 Act repeals the bad debt reserve method of accounting for mutual
savings banks and domestic building and loan associations for tax years
beginning after December 31, 1995. As a result, section 593(d) of the Code is no
longer applicable to treat the Certificates as 'qualifying real property loans.'
 
  Taxation of Holders of Grantor Trust Securities
 
     Holders of Grantor Trust Fractional Interest Securities generally will be
required to report on their federal income tax returns their respective shares
of the income from the Mortgage Loans (including amounts used to pay reasonable
servicing fees and other expenses but excluding amounts payable to Holders of
any corresponding Grantor Trust Strip Securities) and, subject to the
limitations described below, will be entitled to deduct their shares of any such
reasonable servicing fees and other expenses. If a Holder acquires a Grantor
Trust Fractional Interest Security for an amount that differs from its

outstanding principal amount, the amount includible in income on a Grantor Trust
Fractional Interest Security may differ from the amount of interest
distributable thereon. See 'Discount and Premium,' below. Individuals holding a
Grantor Trust Fractional Interest Security directly or through certain
pass-through entities will be allowed a deduction for such reasonable servicing
fees and expenses only to the extent that the aggregate of such Holder's
miscellaneous itemized deductions exceeds 2% of such Holder's adjusted gross
income. Further, Holders (other than corporations) subject to the alternative
minimum tax may not deduct miscellaneous itemized deductions in determining
alternative minimum taxable income.
 
     Holders of Grantor Trust Strip Securities generally will be required to
treat such Securities as 'stripped coupons' under section 1286 of the Code.
Accordingly, such a Holder will be required to treat the excess of the total
amount of payments on such a Security over the amount paid for such Security as
original issue discount and to include such discount in income as it accrues
over the life of such Security. See '--Discount and Premium,' below.
 
     Grantor Trust Fractional Interest Securities may also be subject to the
coupon stripping rules if a class of Grantor Trust Strip Securities is issued as
part of the same series of Securities. The consequences of the application of
the coupon stripping rules would appear to be that any discount arising upon the
purchase of such a Security (and perhaps all stated interest thereon) would be
classified as original issue discount and includible in the Holder's income as
it accrues (regardless of the Holder's method of accounting), as described below
under '--Discount and Premium.' The coupon stripping rules will not apply,
however, if (i) the pass-through rate is no more than 100 basis points lower
than the gross rate of interest payable on the underlying Mortgage Loans and
(ii) the difference between the outstanding principal balance on the Security
and the amount paid for such Security is less than 0.25% of such principal
balance times the weighted average remaining maturity of the Security.

  Sales of Grantor Trust Securities
 
     Any gain or loss recognized on the sale of a Grantor Trust Security (equal
to the difference between the amount realized on the sale and the adjusted basis
of such Grantor Trust Security) will be capital gain or loss, except to the
extent of accrued and unrecognized market discount, which will be treated as
ordinary income, and in the case of banks and other financial institutions
except as provided under section 582(c) of the Code. The adjusted basis of a
Grantor Trust Security will generally equal its cost, increased by any income
reported by the seller (including original issue discount and market discount
income) and reduced (but not below zero) by any previously reported losses, any
amortized premium and by any distributions of principal.
 
  Grantor Trust Reporting
 
     The Trustee will furnish to each Holder of a Grantor Trust Fractional
Interest Security with each distribution a statement setting forth the amount of
such distribution allocable to principal on the underlying Mortgage Loans and to

interest thereon at the related Pass-Through Rate. In addition, within a
reasonable time after the end of each calendar year, based on information
provided by the Master Servicer, the Trustee will furnish to each Holder during
such year such customary factual information as the Master Servicer deems
necessary or desirable to enable Holders of Grantor Trust Securities to prepare
their tax returns and will furnish comparable information to the Internal
Revenue Service (the 'IRS') as and when required to do so by law.
 
REMIC SECURITIES
 
     If provided in a related Prospectus Supplement, an election will be made to
treat a Trust Estate as a REMIC under the Code. Qualification as a REMIC
requires ongoing compliance with certain conditions. With respect to each series
of Securities for which such an election is made, Dewey Ballantine, special tax
counsel to the Sponsor, will deliver its opinion to the Sponsor that (unless
otherwise limited in the related Prospectus Supplement), assuming compliance
with the Pooling and Servicing Agreement, the Trust Estate will be treated as a
REMIC for federal income tax purposes. A Trust Estate for which a REMIC election
is made will be referred to herein as a 'REMIC Trust.' The Securities of each
class will be designated as 'regular interests' in the REMIC Trust except that a
separate class will be designated as the 'residual interest' in the REMIC Trust.
The Prospectus Supplement for each series of Securities will state whether
Securities of each class will constitute a regular interest (a REMIC Regular
Security) or a residual interest (a REMIC Residual Security).
 
     A REMIC Trust will not be subject to federal income tax except with respect
to income from prohibited transactions and in certain other instances described
below. See '--Taxes on a REMIC Trust.' Generally, the total income from the
Mortgage Loans in a REMIC Trust will be taxable to the Holders of the Securities
of that series, as described below.
 
     Regulations issued by the Treasury Department on December 23, 1992 (the
'REMIC Regulations') provide some guidance regarding the federal income tax
consequences associated with the purchase, ownership and disposition of REMIC
Securities. While certain material provisions of the REMIC Regulations are
discussed below, investors should consult their own tax advisors regarding the
possible application of the REMIC Regulations in their specific circumstances.
 
SPECIAL TAX ATTRIBUTES
 
     REMIC Regular Securities and REMIC Residual Securities will be 'regular or
residual interests in a REMIC' within the meaning of section 7701(a)(19)(C)(xi)
of the Code and 'real estate assets' within the meaning of section 856(c)(5)(A)
of the Code. If at any time during a calendar year less than 95% of the assets
of a REMIC Trust consist of 'qualified mortgages' (within the meaning of section
860G(a)(3) of the Code) then the portion of the REMIC Regular Securities and
REMIC Residual Securities that are qualifying assets under those sections during
such calendar year may be limited to the portion of the assets of such REMIC
Trust that are qualified mortgages. Similarly, income on the REMIC Regular
Securities and REMIC Residual Securities will be treated as 'interest on
obligations secured by mortgages on real property' within the meaning of section
856(c)(3)(B) of the Code, subject to the same limitation as set forth in the
preceding sentence. For purposes of applying this limitation, a REMIC Trust
should be treated as owning the assets represented by the qualified mortgages.

The assets of the Trust Estate will include, in addition to the Mortgage Loans,
payments on
 
                                       75
<PAGE>
the Mortgage Loans held pending distribution on the REMIC Regular Securities and
REMIC Residual Securities and any reinvestment income thereon. REMIC Regular
Securities and REMIC Residual Securities held by a financial institution to
which section 585, 586 or 593 of the Code applies will be treated as evidences
of indebtedness for purposes of section 582(c)(1) of the Code. REMIC Regular
Securities will also be qualified mortgages with respect to other REMICs.
 
     The 1996 Act repeals the bad debt reserve method of accounting for mutual
savings banks and domestic building and loan associations for tax years
beginning after December 31, 1995. As a result, section 593(d) of the Code is no
longer applicable to treat the Certificates as 'qualifying real property loans.'
 
  Taxation of Holders of REMIC Regular Securities
 
     Except as indicated below in this federal income tax discussion, the REMIC
Regular Securities will be treated for federal income tax purposes as debt
instruments issued by the REMIC Trust on the date such Securities are first sold
to the public (the 'Settlement Date') and not as ownership interests in the
REMIC Trust or its assets. Holders of REMIC Regular Securities that otherwise
report income under a cash method of accounting will be required to report
income with respect to such Securities under an accrual method. For additional
tax consequences relating to REMIC Regular Securities purchased at a discount or
with premium, see '--Discount and Premium,' below.
 
  Taxation of Holders of REMIC Residual Securities
 
     Daily Portions.  Except as indicated below, a Holder of a REMIC Residual
Security for a REMIC Trust generally will be required to report its daily
portion of the taxable income or net loss of the REMIC Trust for each day during
a calendar quarter that the Holder owned such REMIC Residual Security. For this
purpose, the daily portion shall be determined by allocating to each day in the
calendar quarter its ratable portion of the taxable income or net loss of the
REMIC Trust for such quarter and by allocating the amount so allocated among the
Residual Holders (on such day) in accordance with their percentage interests on
such day. Any amount included in the gross income or allowed as a loss of any
Residual Holder by virtue of this paragraph will be treated as ordinary income
or loss.
 
     The requirement that each Holder of a REMIC Residual Security report its
daily portion of the taxable income or net loss of the REMIC Trust will continue
until there are no Securities of any class outstanding, even though the Holder
of the REMIC Residual Security may have received full payment of the stated
interest and principal on its REMIC Residual Security.
 
     The Trustee will provide to Holders of REMIC Residual Securities of each
series of Securities (i) such information as is necessary to enable them to
prepare their federal income tax returns and (ii) any reports regarding the
Securities of such series that may be required under the Code.
 

     Taxable Income or Net Loss of a REMIC Trust.  The taxable income or net
loss of a REMIC Trust will be the income from the qualified mortgages it holds
and any reinvestment earnings less deductions allowed to the REMIC Trust. Such
taxable income or net loss for a given calendar quarter will be determined in
the same manner as for an individual having the calendar year as the taxable
year and using the accrual method of accounting, with certain modifications. The
first modification is that a deduction will be allowed for accruals of interest
(including any original issue discount, but without regard to the investment
interest limitation in section 163(d) of the Code) on the REMIC Regular
Securities (but not the REMIC Residual Securities), even though REMIC Regular
Securities are for non-tax purposes evidences of beneficial ownership rather
than indebtedness of a REMIC Trust. Second, market discount or premium equal to
the difference between the total stated principal balances of the qualified
mortgages and the basis to the REMIC Trust therein generally will be included in
income (in the case of discount) or deductible (in the case of premium) by the
REMIC Trust as it accrues under a constant yield method, taking into account the
'Prepayment Assumption' (as defined in the Related Prospectus Supplement, see
'--Discount and Premium--Original Issue Discount,' below). The basis to a REMIC
Trust in the qualified mortgages is the aggregate of the issue prices of all the
REMIC Regular Securities and REMIC Residual Securities in the REMIC Trust on the
Settlement Date. If, however, a substantial amount of a class of REMIC Regular
Securities or REMIC Residual Securities has not been sold to the public, then
the fair market value of all the REMIC Regular Securities or REMIC Residual
Securities in that class as of the date of the Prospectus Supplement should be
substituted for the issue price.
 
                                       76
<PAGE>
     Third, no item of income, gain, loss or deduction allocable to a prohibited
transaction (see '--Taxes on a REMIC Trust--Prohibited Transactions' below) will
be taken into account. Fourth, a REMIC Trust generally may not deduct any item
that would not be allowed in calculating the taxable income of a partnership by
virtue of section 703(a)(2) of the Code. Finally, the limitation on
miscellaneous itemized deductions imposed on individuals by section 67 of the
Code will not be applied at the REMIC Trust level to any servicing and guaranty
fees. (See, however, '--Pass-Through of Servicing and Guaranty Fees to
Individuals' below.) In addition, under the REMIC Regulations, any expenses that
are incurred in connection with the formation of a REMIC Trust and the issuance
of the REMIC Regular Securities and REMIC Residual Securities are not treated as
expenses of the REMIC Trust for which a deduction is allowed. If the deductions
allowed to a REMIC Trust exceed its gross income for a calendar quarter, such
excess will be a net loss for the REMIC Trust for that calendar quarter. The
REMIC Regulations also provide that any gain or loss to a REMIC Trust from the
disposition of any asset, including a qualified mortgage or 'permitted
investment' (as defined in section 860G(a)(5) of the Code) will be treated as
ordinary gain or loss.
 
     A Holder of a REMIC Residual Security may be required to recognize taxable
income without being entitled to receive a corresponding amount of cash. This
could occur, for example, if the qualified mortgages are considered to be
purchased by the REMIC Trust at a discount, some or all of the REMIC Regular
Securities are issued at a discount, and the discount included as a result of a
prepayment on a Mortgage Loan that is used to pay principal on the REMIC Regular
Securities exceeds the REMIC Trust's deduction for unaccrued original issue

discount relating to such REMIC Regular Securities. Taxable income may also be
greater in earlier years because interest expense deductions, expressed as a
percentage of the outstanding principal amount of the REMIC Regular Securities,
may increase over time as the earlier classes of REMIC Regular Securities are
paid, whereas interest income with respect to any given Mortgage Loan expressed
as a percentage of the outstanding principal amount of that Mortgage Loan, will
remain constant over time.
 
     Basis Rules and Distributions.  A Holder of a REMIC Residual Security has
an initial basis in its Security equal to the amount paid for such REMIC
Residual Security. Such basis is increased by amounts included in the income of
the Holder and decreased by distributions and by any net loss taken into account
with respect to such REMIC Residual Security. A distribution on a REMIC Residual
Security to a Holder is not included in gross income to the extent it does not
exceed such Holder's basis in the REMIC Residual Security (adjusted as described
above) and, to the extent it exceeds the adjusted basis of the REMIC Residual
Security, shall be treated as gain from the sale of the REMIC Residual Security.
 
     A Holder of a REMIC Residual Security is not allowed to take into account
any net loss for any calendar quarter to the extent such net loss exceeds such
Holder's adjusted basis in its REMIC Residual Security as of the close of such
calendar quarter (determined without regard to such net loss). Any loss
disallowed by reason of this limitation may be carried forward indefinitely to
future calendar quarters and, subject to the same limitation, may be used only
to offset income from the REMIC Residual Security.
 
     Excess Inclusions.  Any excess inclusions with respect to a REMIC Residual
Security are subject to certain special tax rules. With respect to a Holder of a
REMIC Residual Security, the excess inclusion for any calendar quarter is
defined as the excess (if any) of the daily portions of taxable income over the
sum of the 'daily accruals' for each day during such quarter that such REMIC
Residual Security was held by such Holder. The daily accruals are determined by
allocating to each day during a calendar quarter its ratable portion of the
product of the 'adjusted issue price' of the REMIC Residual Security at the
beginning of the calendar quarter and 120% of the 'federal long-term rate' in
effect on the Settlement Date, based on quarterly compounding, and properly
adjusted for the length of such quarter. For this purpose, the adjusted issue
price of a REMIC Residual Security as of the beginning of any calendar quarter
is equal to the issue price of the REMIC Residual Security, increased by the
amount of daily accruals for all prior quarters and decreased by any
distributions made with respect to such REMIC Residual Security before the
beginning of such quarter. The issue price of a REMIC Residual Security is the
initial offering price to the public (excluding bond houses and brokers) at
which a substantial number of the REMIC Residual Securities was sold. The
federal long-term rate is a blend of current yields on Treasury securities
having a maturity of more than nine years, computed and published monthly by the
IRS.
 
     In general, Holders of REMIC Residual Securities with excess inclusion
income cannot offset such income by losses from other activities. For Holders
that are subject to tax only on unrelated business taxable income (as
 
                                       77
<PAGE>

defined in section 511 of the Code), an excess inclusion of such Holder is
treated as unrelated business taxable income. With respect to variable contracts
(within the meaning of section 817 of the Code), a life insurance company cannot
adjust its reserve to the extent of any excess inclusion, except as provided in
regulations. The REMIC Regulations indicate that if a Holder of a REMIC Residual
Security is a member of an affiliated group filing a consolidated income tax
return, the taxable income of the affiliated group cannot be less than the sum
of the excess inclusions attributable to all residual interests in REMICS held
by members of the affiliated group. For a discussion of the effect of excess
inclusions on certain foreign investors that own REMIC Residual Securities, see
'--Foreign Investors' below.
 
     The Treasury Department also has the authority to issue regulations that
would treat all taxable income of a REMIC Trust as excess inclusions if the
REMIC Residual Security does not have 'significant value.' Although the Treasury
Department did not exercise this authority in the REMIC Regulations, future
regulations may contain such a rule. If such a rule were adopted, it is unclear
how significant value would be determined for these purposes. If no such rule is
applicable, excess inclusions should be calculated as discussed above.
 
     In the case of any REMIC Residual Securities that are held by a real estate
investment trust, the aggregate excess inclusions with respect to such REMIC
Residual Securities reduced (but not below zero) by the real estate investment
trust taxable income (within the meaning of section 857(b)(2) of the Code,
excluding any net capital gain) will be allocated among the shareholders of such
trust in proportion to the dividends received by such shareholders from such
trust, and any amount so allocated will be treated as an excess inclusion with
respect to a REMIC Residual Security as if held directly by such shareholder.
Similar rules will apply in the case of regulated investment companies, common
trust funds and certain cooperatives that hold a REMIC Residual Security.
 
     Pass-Through of Servicing and Guaranty Fees to Individuals.  A Holder of a
REMIC Residual Security who is an individual will be required to include in
income a share of any servicing and guaranty fees. A deduction for such fees
will be allowed to such Holder only to the extent that such fees, along with
certain of such Holder's other miscellaneous itemized deductions exceed 2% of
such Holder's adjusted gross income. In addition, a Holder of a REMIC Residual
Security may not be able to deduct any portion of such fees in computing such
Holder's alternative minimum tax liability. A Holder's share of such fees will
generally be determined by (i) allocating the amount of such expenses for each
calendar quarter on a pro rata basis to each day in the calendar quarter, and
(ii) allocating the daily amount among the Holders in proportion to their
respective holdings on such day.
 
  Taxes on a REMIC Trust
 
     Prohibited Transactions.  The Code imposes a tax on a REMIC equal to 100%
of the net income derived from 'prohibited transactions.' In general, a
prohibited transaction means the disposition of a qualified mortgage other than
pursuant to certain specified exceptions, the receipt of investment income from
a source other than a Mortgage Loan or certain other permitted investments, the
receipt of compensation for services, or the disposition of an asset purchased
with the payments on the qualified mortgages for temporary investment pending
distribution on the regular and residual interests.

 
     Contributions to a REMIC after the Startup Day.  The Code imposes a tax on
a REMIC equal to 100% of the value of any property contributed to the REMIC
after the 'startup day' (generally the same as the Settlement Date). Exceptions
are provided for cash contributions to a REMIC (i) during the three month period
beginning on the startup day, (ii) made to a qualified reserve fund by a Holder
of a residual interest, (iii) in the nature of a guarantee, (iv) made to
facilitate a qualified liquidation or clean-up call, and (v) as otherwise
permitted by Treasury regulations.
 
     Net Income from Foreclosure Property.  The Code imposes a tax on a REMIC
equal to the highest corporate rate on 'net income from foreclosure property.'
The terms 'foreclosure property' (which includes property acquired by deed in
lieu of foreclosure) and 'net income from foreclosure property' are defined by
reference to the rules applicable to real estate investment trusts. Generally,
foreclosure property would be treated as such for a period of two years, with
possible extensions. Net income from foreclosure property generally means gain
from the sale of foreclosure property that is inventory property and gross
income from foreclosure property other than qualifying rents and other
qualifying income for a real estate investment trust.
 
                                       78
<PAGE>
  Sales of REMIC Securities
 
     General.  Except as provided below, if a Regular or REMIC Residual Security
is sold, the seller will recognize gain or loss equal to the difference between
the amount realized in the sale and its adjusted basis in the Security. The
adjusted basis of a REMIC Regular Security generally will equal the cost of such
Security to the seller, increased by any original issue discount or market
discount included in the seller's gross income with respect to such Security and
reduced by distributions on such Security previously received by the seller of
amounts included in the stated redemption price at maturity and by any premium
that has reduced the seller's interest income with respect to such Security. See
'--Discount and Premium.' The adjusted basis of a REMIC Residual Security is
determined as described above under '--Taxation of Holders of REMIC Residual
Securities--Basis Rules and Distributions.' Except as provided in the following
paragraph or under section 582(c) of the Code, any such gain or loss will be
capital gain or loss, provided such Security is held as a 'capital asset'
(generally, property held for investment) within the meaning of section 1221 of
the Code.
 
     Gain from the sale of a REMIC Regular Security that might otherwise be
capital gain will be treated as ordinary income to the extent that such gain
does not exceed the excess, if any, of (i) the amount that would have been
includible in the income of the Holder of a REMIC Regular Security had income
accrued at a rate equal to 110% of the 'applicable federal rate' (generally, an
average of current yields on Treasury securities) as of the date of purchase
over (ii) the amount actually includible in such Holder's income. In addition,
gain recognized on such a sale by a Holder of a REMIC Regular Security who
purchased such a Security at a market discount would also be taxable as ordinary
income in an amount not exceeding the portion of such discount that accrued
during the period such Security was held by such Holder, reduced by any market
discount includible in income under the rules described below under '--Discount

and Premium.'
 
     If a Holder of a REMIC Residual Security sells its REMIC Residual Security
at a loss, the loss will not be recognized if, within six months before or after
the sale of the REMIC Residual Security, such Holder purchases another residual
interest in any REMIC or any interest in a taxable mortgage pool (as defined in
section 7701(i) of the Code) comparable to a residual interest in a REMIC. Such
disallowed loss would be allowed upon the sale of the other residual interest
(or comparable interest) if the rule referred to in the preceding sentence does
not apply to that sale. While this rule may be modified by Treasury regulations,
no such regulations have yet been published.
 
     Transfers of REMIC Residual Securities.  Section 860E(e) of the Code
imposes a substantial tax, payable by the transferor (or, if a transfer is
through a broker, nominee, or other middleman as the transferee's agent, payable
by that agent) upon any transfer of a REMIC Residual Security to a disqualified
organization and upon a pass-through entity (including regulated investment
companies, real estate investment trusts, common trust funds, partnerships,
trusts, estates, certain cooperatives, and nominees) that owns a REMIC Residual
Security if such pass-through entity has a disqualified organization as a
record-holder. For purposes of the preceding sentence, a transfer includes any
transfer of record or beneficial ownership, whether pursuant to a purchase, a
default under a secured lending agreement or otherwise.
 
     The term 'disqualified organization' includes the United States, any state
or political subdivision thereof, any foreign government, any international
organization, or any agency or instrumentality of the foregoing (other than
certain taxable instrumentalities), any cooperative organization furnishing
electric energy or providing telephone service to persons in rural areas, or any
organization (other than a farmers' cooperative) that is exempt from federal
income tax, unless such organization is subject to the tax on unrelated business
income. Moreover, an entity will not qualify as a REMIC unless there are
reasonable arrangements designed to ensure that (i) residual interests in such
entity are not held by disqualified organizations and (ii) information necessary
for the application of the tax described herein will be made available.
Restrictions on the transfer of a REMIC Residual Security and certain other
provisions that are intended to meet this requirement are described in the
Pooling and Servicing Agreement, and will be discussed more fully in the related
Prospectus Supplement relating to the offering of any REMIC Residual Security.
In addition, a pass-through entity (including a nominee) that holds a REMIC
Residual Security may be subject to additional taxes if a disqualified
organization is a record-holder therein. A transferor of a REMIC Residual
Security (or an agent of a transferee of a REMIC Residual Security, as the case
may be) will be relieved of such tax liability if (i) the transferee furnishes
to the transferor (or the transferee's agent) an affidavit that the transferee
is not a disqualified organization, and (ii) the transferor (or the
 
                                       79
<PAGE>
transferee's agent) does not have actual knowledge that the affidavit is false
at the time of the transfer. Similarly, no such tax will be imposed on a
pass-through entity for a period with respect to an interest therein owned by a
disqualified organization if (i) the record-holder of such interest furnishes to
the pass-through entity an affidavit that it is not a disqualified organization,

and (ii) during such period, the pass-through entity has no actual knowledge
that the affidavit is false.
 
     Under the REMIC Regulations, a transfer of a 'noneconomic residual
interest' to a U.S. Person (as defined below in '--Foreign Investors--Grantor
Trust Securities and REMIC Regular Securities') will be disregarded for all
federal tax purposes unless no significant purpose of the transfer is to impede
the assessment or collection of tax. A REMIC Residual Security would be treated
as constituting a noneconomic residual interest unless, at the time of the
transfer, (i) the present value of the expected future distributions on the
REMIC Residual Security is no less than the product of the present value of the
'anticipated excess inclusions' with respect to such Security and the highest
corporate 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 applicable REMIC Trust in an amount sufficient to satisfy the liability
for income tax on any 'excess inclusions' at or after the time when such
liability accrues. Anticipated excess inclusions are the excess inclusions that
are anticipated to be allocated to each calendar quarter (or portion thereof)
following the transfer of a REMIC Residual Security, determined as of the date
such Security is transferred and based on events that have occurred as of that
date and on the Prepayment Assumption. See '--Discount and Premium' and
'--Taxation of Holders of REMIC Residual Securities--Excess Inclusions.'
 
     The REMIC Regulations provide that a significant purpose to impede the
assessment or collection of tax exists if, at the time of the transfer, a
transferor of a REMIC Residual Security has 'improper knowledge' (i.e., either
knew, or should have known, that the transferee would be unwilling or unable to
pay taxes due on its share of the taxable income of the REMIC Trust). A
transferor is presumed not to have improper knowledge if (i) the transferor
conducts, at the time of a transfer, a reasonable investigation of the financial
condition of the transferee and, as a result of the investigation, the
transferor finds that the transferee has historically paid its debts as they
come due and finds no significant evidence to indicate that the transferee will
not continue to pay its debts as they come due in the future; and (ii) the
transferee makes certain representations to the transferor in the affidavit
relating to disqualified organizations discussed above. Transferors of a REMIC
Residual Security should consult with their own tax advisors for further
information regarding such transfers.
 
     Reporting and Other Administrative Matters.  For purposes of the
administrative provisions of the Code, each REMIC Trust will be treated as a
partnership and the Holders of REMIC Residual Securities will be treated as
partners. The Trustee will prepare, sign and file federal income tax returns for
each REMIC Trust, which returns are subject to audit by the IRS. Moreover,
within a reasonable time after the end of each calendar year, the Trustee will
furnish to each Holder that received a distribution during such year a statement
setting forth the portions of any such distributions that constitute interest
distributions, original issue discount, and such other information as is
required by Treasury regulations and, with respect to Holders of REMIC Residual
Securities in a REMIC Trust, information necessary to compute the daily portions
of the taxable income (or net loss) of such REMIC Trust for each day during such
year. The Trustee will also act as the tax matters partner for each REMIC Trust,
either in its capacity as a Holder of a REMIC Residual Security or in a
fiduciary capacity. Each Holder of a REMIC Residual Security, by the acceptance

of its REMIC Residual Security, agrees that the Trustee will act as its
fiduciary in the performance of any duties required of it in the event that it
is the tax matters partner.
 
     Each Holder of a REMIC Residual Security is required to treat items on its
return consistently with the treatment on the return of the REMIC Trust, unless
the Holder either files a statement identifying the inconsistency or establishes
that the inconsistency resulted from incorrect information received from the
REMIC Trust. The IRS may assert a deficiency resulting from a failure to comply
with the consistency requirement without instituting an administrative
proceeding at the REMIC Trust level. Unless otherwise specified in the related
Prospectus Supplement, the Trustee does not intend to register any REMIC Trust
as a tax shelter pursuant to section 6111 of the Code.
 
  Termination
 
     In general, no special tax consequences will apply to a Holder of a REMIC
Regular Security upon the termination of a REMIC Trust by virtue of the final
payment or liquidation of the last Mortgage Loan remaining
 
                                       80
<PAGE>
in the Trust Estate. If a Holder of a REMIC Residual Security's adjusted basis
in its REMIC Residual Security at the time such termination occurs exceeds the
amount of cash distributed to such Holder in liquidation of its interest,
although the matter is not entirely free from doubt, it would appear that the
Holder of the REMIC Residual Security is entitled to a loss equal to the amount
of such excess.
 
DEBT SECURITIES
 
  General
 
     With respect to each series of Debt Securities, Dewey Ballantine, special
tax counsel to the Sponsor, will deliver its opinion to the Sponsor that (unless
otherwise limited in the related Prospectus Supplement) the Securities will be
classified as debt of the Sponsor secured by the related Mortgage Loans.
Consequently, the Debt Securities will not be treated as ownership interests in
the Mortgage Loans or the Trust. Holders will be required to report income
received with respect to the Debt Securities in accordance with their normal
method of accounting. For additional tax consequences relating to Debt
Securities purchased at a discount or with premium, see '--Discount and
Premium,' below.
 
  Special Tax Attributes
 
     As described above, Grantor Trust Securities will possess certain special
tax attributes by virtue of their being ownership interests in the underlying
Mortgage Loans. Similarly, REMIC Securities will possess similar attributes by
virtue of the REMIC provisions of the Code. In general, Debt Securities will not
possess such special tax attributes. Investors to whom such attributes are
important should consult their own tax advisors regarding investment in Debt
Securities.
 

  Sale or Exchange
 
     If a Holder of a Debt Security sells or exchanges such Security, the Holder
will recognize gain or loss equal to the difference, if any, between the amount
received and the Holder's adjusted basis in the Security. The adjusted basis in
the Security generally will equal its initial cost, increased by any original
issue discount or market discount previously included in the seller's gross
income with respect to the Security and reduced by the payments previously
received on the Security, other than payments of qualified stated interest, and
by any amortized premium.
 
     In general (except as described in '--Discount and Premium--Market
Discount,' below), except for certain financial institutions subject to section
582(c) of the Code, any gain or loss on the sale or exchange of a Debt Security
recognized by an investor who holds the Security as a capital asset (within the
meaning of section 1221 of the Code), will be capital gain or loss and will be
long-term or short-term depending on whether the Security has been held for more
than one year.
 
DISCOUNT AND PREMIUM
 
     A Security purchased for an amount other than its outstanding principal
amount will be subject to the rules governing original issue discount, market
discount or premium. In addition, all Grantor Trust Strip Securities and certain
Grantor Trust Fractional Interest Securities will be treated as having original
issue discount by virtue of the coupon stripping rules in section 1286 of the
Code. In very general terms, (i) original issue discount is treated as a form of
interest and must be included in a Holder's income as it accrues (regardless of
the Holder's regular method of accounting) using a constant yield method; (ii)
market discount is treated as ordinary income and must be included in a Holder's
income as principal payments are made on the Security (or upon a sale of a
Security); and (iii) if a Holder so elects, premium may be amortized over the
life of the Security and offset against inclusions of interest income. These tax
consequences are discussed in greater detail below.
 
  Original Issue Discount
 
     In general, a Security will be considered to be issued with original issue
discount equal to the excess, if any, of its 'stated redemption price at
maturity' over its 'issue price.' The issue price of a Security is the initial
offering price to the public (excluding bond houses and brokers) at which a
substantial number of the Securities
 
                                       81

<PAGE>
was sold. The issue price also includes any accrued interest attributable to the
period between the beginning of the first Remittance Period and the Settlement
Date. The stated redemption price at maturity of a Security that has a notional
principal amount or receives principal only or that is or may be an Accrual
Security is equal to the sum of all distributions to be made under such
Security. The stated redemption price at maturity of any other Security is its
stated principal amount, plus an amount equal to the excess (if any) of the
interest payable on the first Payment Date over the interest that accrues for

the period from the Settlement Date to the first Payment Date.
 
     Notwithstanding the general definition, original issue discount will be
treated as zero if such discount is less than 0.25% of the stated redemption
price at maturity multiplied by its weighted average life. The weighted average
life of a Security is apparently computed for this purpose as the sum, for all
distributions included in the stated redemption price at maturity of the amounts
determined by multiplying (i) the number of complete years (rounding down for
partial years) from the Settlement Date until the date on which each such
distribution is expected to be made under the assumption that the Mortgage Loans
prepay at the rate specified in the related Prospectus Supplement (the
'Prepayment Assumption') by (ii) a fraction, the numerator of which is the
amount of such distribution and the denominator of which is the Security's
stated redemption price at maturity. If original issue discount is treated as
zero under this rule, the actual amount of original issue discount must be
allocated to the principal distributions on the Security and, when each such
distribution is received, gain equal to the discount allocated to such
distribution will be recognized.
 
     Section 1272(a)(6) of the Code contains special original issue discount
rules directly applicable to REMIC Securities and Debt Securities and applicable
by analogy to Grantor Trust Securities. Investors in Grantor Trust Securities
should be aware that there can be no assurance that the rules described below
will be applied to such Securities. Under these rules (described in greater
detail below), (i) the amount and rate of accrual of original issue discount on
each series of Securities will be based on (x) the Prepayment Assumption, and
(y) in the case of a Security calling for a variable rate of interest, an
assumption that the value of the index upon which such variable rate is based
remains equal to the value of that rate on the Settlement Date, and (ii)
adjustments will be made in the amount of discount accruing in each taxable year
in which the actual prepayment rate differs from the Prepayment Assumption.
 
     Section 1272(a)(6)(B)(iii) of the Code requires that the prepayment
assumption used to calculate original issue discount be determined in the manner
prescribed in Treasury regulations. To date, no such regulations have been
promulgated. The legislative history of this Code provision indicates that the
assumed prepayment rate must be the rate used by the parties in pricing the
particular transaction. The Sponsor anticipates that the Prepayment Assumption
for each series of Securities will be consistent with this standard. The Sponsor
makes no representation, however, that the Mortgage Loans for a given series
will prepay at the rate reflected in the Prepayment Assumption for that series
or at any other rate. Each investor must make its own decision as to the
appropriate prepayment assumption to be used in deciding whether or not to
purchase any of the Securities.
 
     Each Securityholder must include in gross income the sum of the 'daily
portions' of original issue discount on its Security for each day during its
taxable year on which it held such Security. For this purpose, in the case of an
original Holder, the daily portions of original issue discount will be
determined as follows. A calculation will first be made of the portion of the
original issue discount that accrued during each 'accrual period.' The Trustee
will supply, at the time and in the manner required by the IRS, to
Securityholders, brokers and middlemen information with respect to the original
issue discount accruing on the Securities. Unless otherwise disclosed in the

related Prospectus Supplement, the Trustee will report original issue discount
based on accrual periods of one month, each beginning on a payment date (or, in
the case of the first such period, the Settlement Date) and ending on the day
before the next payment date.
 
     Under section 1272(a)(6) of the Code, the portion of original issue
discount treated as accruing for any accrual period will equal the excess, if
any, of (i) the sum of (A) the present values of all the distributions remaining
to be made on the Security, if any, as of the end of the accrual period and (B)
the distribution made on such Security during the accrual period of amounts
included in the stated redemption price at maturity, over (ii) the adjusted
issue price of such Security at the beginning of the accrual period. The present
value of the remaining distributions referred to in the preceding sentence will
be calculated based on (i) the yield to maturity of the Security, calculated as
of the Settlement Date, giving effect to the Prepayment Assumption, (ii) events
(including actual prepayments) that have occurred prior to the end of the
accrual period, (iii) the Prepayment
 
                                       82
<PAGE>
Assumption, and (iv) in the case of a Security calling for a variable rate of
interest, an assumption that the value of the index upon which such variable
rate is based remains the same as its value on the Settlement Date over the
entire life of such Security. The adjusted issue price of a Security at any time
will equal the issue price of such Security, increased by the aggregate amount
of previously accrued original issue discount with respect to such Security, and
reduced by the amount of any distributions made on such Security as of that time
of amounts included in the stated redemption price at maturity. The original
issue discount accruing during any accrual period will then be allocated ratably
to each day during the period to determine the daily portion of original issue
discount.
 
     In the case of Grantor Trust Strip Securities and certain REMIC Securities,
the calculation described in the preceding paragraph may produce a negative
amount of original issue discount for one or more accrual periods. No definitive
guidance has been issued regarding the treatment of such negative amounts. The
legislative history to section 1272(a)(6) indicates that such negative amounts
may be used to offset subsequent positive accruals but may not offset prior
accruals and may not be allowed as a deduction item in a taxable year in which
negative accruals exceed positive accruals. Holders of such Securities should
consult their own tax advisors concerning the treatment of such negative
accruals.
 
     A subsequent purchaser of a Security that purchases such Security at a cost
less than its remaining stated redemption price at maturity also will be
required to include in gross income for each day on which it holds such
Security, the daily portion of original issue discount with respect to such
Security (but reduced, if the cost of such Security to such purchaser exceeds
its adjusted issue price, by an amount equal to the product of (i) such daily
portion and (ii) a constant fraction, the numerator of which is such excess and
the denominator of which is the sum of the daily portions of original issue
discount on such Security for all days on or after the day of purchase).
 
  Market Discount

 
     A Holder that purchases a Security at a market discount, that is, at a
purchase price less than the remaining stated redemption price at maturity of
such Security (or, in the case of a Security with original issue discount, its
adjusted issue price), will be required to allocate each principal distribution
first to accrued market discount on the Security, and recognize ordinary income
to the extent such distribution does not exceed the aggregate amount of accrued
market discount on such Security not previously included in income. With respect
to Securities that have unaccrued original issue discount, such market discount
must be included in income in addition to any original issue discount. A Holder
that incurs or continues indebtedness to acquire a Security at a market discount
may also be required to defer the deduction of all or a portion of the interest
on such indebtedness until the corresponding amount of market discount is
included in income. In general terms, market discount on a Security may be
treated as accruing either (i) under a constant yield method or (ii) in
proportion to remaining accruals of original issue discount, if any, or if none,
in proportion to remaining distributions of interest on the Security, in any
case taking into account the Prepayment Assumption. The Trustee will make
available, as required by the IRS, to Holders of Securities information
necessary to compute the accrual of market discount.
 
     Notwithstanding the above rules, market discount on a Security will be
considered to be zero if such discount is less than 0.25% of the remaining
stated redemption price at maturity of such Security multiplied by its weighted
average remaining life. Weighted average remaining life presumably would be
calculated in a manner similar to weighted average life, taking into account
payments (including prepayments) prior to the date of acquisition of the
Security by the subsequent purchaser. If market discount on a Security is
treated as zero under this rule, the actual amount of market discount must be
allocated to the remaining principal distributions on the Security and, when
each such distribution is received, gain equal to the discount allocated to such
distribution will be recognized.
 
  Securities Purchased at a Premium
 
     A purchaser of a Security that purchases such Security at a cost greater
than its remaining stated redemption price at maturity will be considered to
have purchased such Security (a 'Premium Security') at a premium. Such a
purchaser need not include in income any remaining original issue discount and
may elect, under section 171(c)(2) of the Code, to treat such premium as
'amortizable bond premium.' If a Holder makes such an election, the amount of
any interest payment that must be included in such Holder's income for each
period ending on a Payment Date will be reduced by the portion of the premium
allocable to such period based on the
 
                                       83
<PAGE>
Premium Security's yield to maturity. The legislative history of the Tax Reform
Act of 1986 states that such premium amortization should be made under
principles analogous to those governing the accrual of market discount (as
discussed above under '--Market Discount'). If such election is made by the
Holder, the election will also apply to all bonds the interest on which is not
excludible from gross income ('fully taxable bonds') held by the Holder at the
beginning of the first taxable year to which the election applies and to all

such fully taxable bonds thereafter acquired by it, and is irrevocable without
the consent of the IRS. If such an election is not made, (i) such a Holder must
include the full amount of each interest payment in income as it accrues, and
(ii) the premium must be allocated to the principal distributions on the Premium
Security and, when each such distribution is received, a loss equal to the
premium allocated to such distribution will be recognized. Any tax benefit from
the premium not previously recognized will be taken into account in computing
gain or loss upon the sale or disposition of the Premium Security.
 
     Some Securities may provide for only nominal distributions of principal in
comparison to the distributions of interest thereon. It is possible that the IRS
or the Treasury Department may issue guidance excluding such Securities from the
rules generally applicable to debt instruments issued at a premium. In
particular, it is possible that such a Security will be treated as having
original issue discount equal to the excess of the total payments to be received
thereon over its issue price. In such event, section 1272(a)(6) of the Code
would govern the accrual of such original issue discount, but a Holder would
recognize substantially the same income in any given period as would be
recognized if an election were made under section 171(c)(2) of the Code. Unless
and until the Treasury Department or the IRS publishes specific guidance
relating to the tax treatment of such Securities, the Trustee intends to furnish
tax information to Holders of such Securities in accordance with the rules
described in the preceding paragraph.
 
  Special Election
 
     For any Security acquired on or after April 4, 1994, a Holder may elect to
include in gross income all 'interest' that accrues on the Security by using a
constant yield method. For purposes of the election, the term 'interest'
includes stated interest, acquisition discount, original issue discount, de
minimis original issue discount, market discount, de minimis market discount and
unstated interest as adjusted by any amortizable bond premium or acquisition
premium. A Holder should consult its own tax advisor regarding the time and
manner of making and the scope of the election and the implementation of the
constant yield method.
 
BACKUP WITHHOLDING
 
     Distributions of interest and principal, as well as distributions of
proceeds from the sale of Securities, may be subject to the 'backup withholding
tax' under section 3406 of the Code at a rate of 31% if recipients of such
distributions fail to furnish to the payor certain information, including their
taxpayer identification numbers, or otherwise fail to establish an exemption
from such tax. Any amounts deducted and withheld from a distribution to a
recipient would be allowed as a credit against such recipient's federal income
tax. Furthermore, certain penalties may be imposed by the IRS on a recipient of
distributions that is required to supply information but that does not do so in
the proper manner.
 
FOREIGN INVESTORS
 
  Grantor Trust Securities and REMIC Regular Securities
 
     Distributions made on a Grantor Trust Security or a REMIC Regular Security

to, or on behalf of, a Holder that is not a U.S. Person generally will be exempt
from U.S. federal income and withholding taxes. 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 or any
political subdivision thereof, an estate that is subject to U.S. federal income
tax regardless of the source of its income, or a trust if a court within the
United States can exercise primary supervision over its administration and at
least one United States fiduciary has the authority to control all substantial
decisions of the trust. This exemption is applicable provided (a) the Holder is
not subject to U.S. tax as a result of a connection to the United States other
than ownership of the Security, (b) the Holder signs a statement under penalties
of perjury that certifies that such Holder is not a U.S. Person, and provides
the name and address of such Holder, and (c) the last U.S. Person in the chain
of payment to the Holder receives such statement from such Holder or a financial
institution holding on its behalf and does not have actual knowledge
 
                                       84
<PAGE>
that such statement is false. Holders should be aware that the IRS might take
the position that this exemption does not apply to a Holder that also owns 10%
or more of the REMIC Residual Securities of any REMIC trust, or to a Holder that
is a 'controlled foreign corporation' described in section 881(c)(3)(C) of the
Code.
 
  REMIC Residual Securities
 
     Amounts distributed to a Holder of a REMIC Residual Security that is a not
a U.S. Person generally will be treated as interest for purposes of applying the
30% (or lower treaty rate) withholding tax on income that is not effectively
connected with a U.S. trade or business. Temporary Treasury Regulations clarify
that amounts not constituting excess inclusions that are distributed on a REMIC
Residual Security to a Holder that is not a U.S. Person generally will be exempt
from U.S. federal income and withholding tax, subject to the same conditions
applicable to distributions on Grantor Trust Securities and REMIC Regular
Securities, as described above, but only to the extent that the obligations
directly underlying the REMIC Trust that issued the REMIC Residual Security
(e.g., Mortgage Loans or regular interests in another REMIC) were issued after
July 18, 1984. In no case will any portion of REMIC income that constitutes an
excess inclusion be entitled to any exemption from the withholding tax or a
reduced treaty rate for withholding. See '--REMIC Securities--Taxation of
Holders of REMIC Residual Securities--Excess Inclusions.'
 
                              ERISA CONSIDERATIONS
 
     The Employee Retirement Income Security Act of 1974, as amended ('ERISA'),
imposes certain fiduciary and prohibited transaction restrictions on employee
pension and welfare benefit plans subject to ERISA ('ERISA Plans'). Section 4975
of the Code imposes essentially the same prohibited transaction restrictions on
tax-qualified retirement plans described in section 401(a) of the Code
('Qualified Retirement Plans') and on Individual Retirement Accounts ('IRAs')
described in section 408 of the Code (collectively, 'Tax-Favored Plans').
 
     Certain employee benefit plans, such as governmental plans (as defined in
Section 3(32) of ERISA), are not subject to the ERISA requirements discussed

herein. Accordingly, assets of such plans may be invested in Securities without
regard to the ERISA considerations described below, subject to the provisions of
applicable federal and state law. Any such plan that is a Qualified Retirement
Plan and exempt from taxation under sections 401(a) and 501(a) of the Code,
however, is subject to the prohibited tran saction rules set forth in section
503 of the Code.
 
     Section 404 of ERISA imposes general fiduciary requirements, including
those of investment prudence and diversification and the requirement that a
Plan's investment be made in accordance with the documents governing the Plan.
In addition, Section 406 of ERISA and section 4975 of the Code prohibit a broad
range of transactions involving assets of ERISA Plans and Tax-Favored Plans
(collectively, 'Plans') and persons ('Parties in Interest' under ERISA or
'Disqualified Persons' under the Code) who have certain specified relationships
to the Plans, unless a statutory or administrative exemption is available.
Certain Parties in Interest (or Disqualified Persons) that participate in a
prohibited transaction may be subject to a penalty (or an excise tax) imposed
pursuant to Section 502(i) of ERISA or section 4975 of the Code, unless a
statutory or administrative exemption is available.
 
PLAN ASSET REGULATIONS
 
     A Plan's investment in Securities may cause the Mortgage Loans included in
a Mortgage Pool to be deemed Plan assets. The U.S. Department of Labor (the
'DOL') has promulgated regulations (the 'DOL Regulations') concerning whether or
not a Plan's assets would be deemed to include an interest in the underlying
assets of an entity (such as a Trust Estate), for purposes of applying the
general fiduciary responsibility provisions of ERISA and the prohibited
transaction provisions of ERISA and the Code, when a Plan acquires an 'equity
interest' (such as a Security) in such entity. Because of the factual nature of
certain of the rules set forth in the DOL Regulations, an investing Plan's
assets either may be deemed to include an interest in the assets of a Trust
Estate or may be deemed merely to include its interest in the Securities.
Therefore, Plans should not acquire or hold Securities in reliance upon the
availability of any exception under the DOL Regulations.
 
                                       85
<PAGE>
     The prohibited transaction provisions of Section 406 of ERISA and section
4975 of the Code may apply to a Trust Estate and cause the Sponsor, the Master
Servicer, any Sub-Servicer, the Trustee, the obligor under any Credit
Enhancement mechanism or certain affiliates thereof, to be considered or become
Parties in Interest or Disqualified Persons with respect to an investing Plan.
If so, the acquisition or holding of Securities by or on behalf of the investing
Plan could also give rise to a prohibited trans action under ERISA and the Code,
unless some statutory or administrative exemption is available. Securities
acquired by a Plan would be assets of that Plan. Under the DOL Regulations, the
Trust Estate, including the Mortgage Loans and the other assets held in the
Trust Estate, may also be deemed to be assets of each Plan that acquires
Securities. Special caution should be exercised before the assets of a Plan are
used to acquire a Security in such circumstances, especially if, with respect to
such assets, the Sponsor, the Master Servicer, any Sub-Servicer, the Trustee,
the obligor under any Credit Enhancement mechanism or an affiliate thereof
either (i) has investment discretion with respect to the investment of Plan

assets; or (ii) has authority or responsibility to give (or regularly gives)
investment advice with respect to Plan assets for a fee pursuant to an agreement
or understanding that such advice will serve as a primary basis for investment
decisions with respect to such assets.
 
     Any person who has discretionary authority or control respecting the
management or disposition of Plan assets, and any person who provides investment
advice with respect to such assets for a fee (in the manner described above), is
a fiduciary of the investing Plan. If the Mortgage Loans were to constitute Plan
assets, then any party exercising management or discretionary control regarding
those assets may be deemed to be a Plan 'fiduciary,' and thus subject to the
fiduciary requirements of ERISA and the prohibited transaction provisions of
ERISA and section 4975 of the Code with respect to the investing Plan. In
addition, if the Mortgage Loans were to constitute Plan assets, then the
acquisition or holding of Securities by a Plan, as well as the operation of the
Trust Estate, may constitute or involve a prohibited transaction under ERISA and
the Code.
 
PROHIBITED TRANSACTION CLASS EXEMPTION
 
     The DOL has issued an administrative exemption, Prohibited Transaction
Class Exemption 83-1 ('PTCE 83-1'), which generally exempts from the prohibited
transaction provisions of section 406(a) of ERISA, and from the excise taxes
imposed by sections 4975(a) and (b) of the Code by reason of section
4975(c)(1)(A) through (D) of the Code, certain transactions involving
residential mortgage pool investment trusts relating to the purchase, sale and
holding of securities in the initial issuance of Securities and the servicing
and operation of 'mortgage pools' (as defined below). PTCE 83-1 permits, subject
to certain general and specific conditions, transactions which might otherwise
be prohibited between Plans and Parties in Interest (or Disqualified Persons)
with respect to those Plans, related to the origination, maintenance and
termination of mortgage pools and the acquisition and holding of certain
mortgage pool pass-through Securities representing interests in such mortgage
pools by Plans, whether or not the Plan's assets would be deemed to include an
ownership interest in the mortgage loans in the mortgage pool. PTCE 83-1 is not
available for mortgage pools that include Cooperative Loans and does not provide
an exemption for Subordinate Securities.
 
     PTCE 83-1 defines the term 'mortgage pool' as 'an investment pool the
corpus of which (1) is held in trust; and (2) consists solely of (a) interest
bearing obligations secured by either first or second mortgages or deeds of
trust on one- to four-family residential property; (b) property which had
secured obligations and which has been acquired by foreclosure; and (c)
undistributed cash.' The Sponsor expects that each pool of Mortgage Loans (other
than pools including Junior Lien Loans which are not in the second lien
position, Cooperative Loans or Multi-Family Loans) will be a 'mortgage pool'
within the meaning of PTCE 83-1.
 
     PTCE 83-1 defines the term 'mortgage pool pass-through certificate' as a
'certificate representing a beneficial undivided fractional interest in a
mortgage pool and entitling the holder of such certificate to pass-through
payment of principal and interest from the pooled mortgage loans, less any fees
retained by the pool sponsor.' The Sponsor has been advised that, for purposes
of applying PTCE 83-1, the term 'mortgage pool pass-through certificate' would

include (i) Securities representing interests in a Trust Estate consisting of
Mortgage Loans issued in a series consisting of only a single class of
Securities; and (ii) Senior Securities representing interests in a Trust Estate
consisting of Mortgage Loans issued in a series in which there is only one class
of Senior Securities; provided that the Securities described in clauses (i) and
(ii) evidence the beneficial ownership of a specified portion of both future
interest payments and future principal payments with respect to the Mortgage
Loans.
 
                                       86
<PAGE>
     It is not clear whether all types of Securities that may be offered
hereunder would be 'mortgage pass-through certificates' for purposes of applying
PTCE 83-1, including, but not limited to, (a) a class of Securities that
evidences the beneficial ownership of interest payments only or principal
payments only, disproportionate interest and principal payments, or nominal
principal or interest payments, such as the Strip Securities; or (b) Securities
in a series including classes of Securities which differ as to timing,
sequential order, rate or amount of distributions of principal or interest or
both, or as to which distributions of principal or interest or both on any class
may be made upon the occurrence of specified events, in accordance with a
schedule or formula, or on the basis of collections from designated portions of
the Mortgage Pool; or (c) Securities evidencing an interest in a Trust Estate as
to which two or more REMIC elections have been made; or (d) a series including
other types of multiple classes. Accordingly, until further clarification by the
DOL, Plans should not acquire or hold Securities representing interests
described in this paragraph in reliance upon the availability of PTCE 83-1
without first consulting with their counsel regarding the application of PTCE
83-1 to the proposed acquisition and holding of such Securities.
 
     PTCE 83-1 sets forth three general conditions that must be satisfied for
any transaction involving the purchase, sale and holding of 'mortgage pool
pass-through certificates' and the servicing and operation of the 'mortgage
pool' to be eligible for exemption: (1) the pool trustee must not be an
affiliate of the pool sponsor; (2) a system of insurance or other protection for
the pooled mortgage loans and property securing such loans, and for indemnifying
securityholders against reductions in pass-through payments due to property
damage or defaults in loan payments in an amount not less than the greater of 1%
of the aggregate principal balance of all covered pooled mortgages, or the
principal balance of the largest covered mortgage, must be maintained; and (3)
the amount of the payment retained by the pool sponsor together with other funds
inuring to its benefit must be limited to not more than adequate consideration
for forming the mortgage pools plus reasonable compensation for services
provided by the pool sponsor to the mortgage pool. PTCE 83-1 also imposes
additional specific conditions for certain types of transactions involving an
investing Plan and for situations in which the Parties in Interest or
Disqualified Persons are fiduciaries.
 
     The Prospectus Supplement for a series will set forth whether the Trustee
in respect of that series is affiliated with the Sponsor. If the Credit
Enhancement mechanism for a series of Securities constitutes a system of
insurance or other protection within the meaning of PTCE 83-1 and is maintained
in an amount not less than the greater of 1% of the aggregate principal balance
of the Mortgage Loans or the principal balance of the largest Mortgage Loan,

then the Sponsor has been advised that the second general condition referred to
above will be satisfied. The Sponsor will not receive total compensation for
forming and providing services to the Mortgage Pools which will be more than
adequate consideration. Each Plan fiduciary responsible for making the
investment decision whether to acquire or hold Securities must make its own
determination as to whether (i) the Securities constitute 'mortgage pool pass
through certificates' for purposes of applying PTCE 83-1, (ii) the second and
third general conditions will be satisfied, and (iii) the specific conditions,
not discussed herein, of PTCE 83-1 have been satisfied.
 
     It should be noted that in promulgating PTCE 83-1 and its predecessor, the
DOL did not have under its consideration interests in pools of the exact nature
described herein. There are other class and individual prohibited transaction
exemptions issued by the DOL that could apply to a Plan's acquisition or holding
of Securities. There can be no assurance that any of those exemptions will apply
with respect to any particular Plan that acquires or holds Securities or, even
if all of the conditions specified therein were satisfied, that the exemption
would apply to all transactions involving the Trust Estate. The related
Prospectus Supplement under 'ERISA Considerations' may contain additional
information regarding the application of PTCE 83-1, or other prohibited
transaction exemptions that may be available, with respect to the series offered
thereby.
 
TAX EXEMPT INVESTORS
 
     A Plan that is exempt from federal income taxation pursuant to Section 501
of the Code (a 'Tax Exempt Investor') nonetheless will be subject to federal
income taxation to the extent that its income is unrelated business taxable
income within the meaning of Section 512 of the Code. All 'excess inclusions' of
a REMIC allocated to a REMIC Residual Security held by a Tax Exempt Investor

CONSULTATION WITH COUNSEL
 
     Any Plan fiduciary that proposes to cause a Plan to acquire or hold
Securities should consult with its counsel with respect to the potential
applicability of the fiduciary responsibility provisions of ERISA and the
prohibited transaction provisions of ERISA and the Code to the proposed
investment and the availability of PTCE 83-1 or any other prohibited transaction
exemption.
 
                            LEGAL INVESTMENT MATTERS
 
     Certain classes of Securities offered hereby and by the related Prospectus
Supplement will constitute 'mortgage related securities' for purposes of the
Secondary Mortgage Market Enhancement Act of 1984 ('SMMEA') so long as they are
rated in at least the second highest rating category by any Rating Agency, and
as such may be legal investments for persons, trusts, corporations,
partnerships, associations, business trusts and business entities (including

depository institutions, life insurance companies and pension funds) created
pursuant to or existing under the laws of the United States or of any State
whose authorized investments are subject to state regulation to the same extent
that, under applicable law, obligations issued by or guaranteed as to principal
and interest by the United States or any agency or instrumentality thereof
constitute legal investments for such entities. Under SMMEA, if a State enacted
legislation on or prior to October 3, 1991 specifically limiting the legal
investment authority of any such entities with respect to 'mortgage related
securities,' such securities will constitute legal investments for entities
subject to such legislation only to the extent provided therein. Certain States
have enacted legislation which overrides the preemption provisions of SMMEA.
SMMEA provides, however, that in no event will the enactment of any such
legislation affect the validity of any contractual commitment to purchase, hold
or invest in 'mortgage related securities,' or require the sale or other
disposition of such securities, so long as such contractual commitment was made
or such securities acquired prior to the enactment of such legislation.
 
     SMMEA also amended the legal investment authority of federally-chartered
depository institutions as follows: federal savings and loan associations and
federal savings banks may invest in, sell or otherwise deal with 'mortgage
related securities' without limitation as to the percentage of their assets
represented thereby, federal credit unions may invest in such securities, and
national banks may purchase such securities for their own account without regard
to the limitations generally applicable to investment securities set forth in 12
U.S.C. 24 (Seventh), subject in each case to such regulations as the applicable
federal regulatory authority may prescribe.
 
     The Federal Financial Institutions Examination Council has adopted a
supervisory policy statement (the 'Policy Statement'), applicable to all
depository institutions, setting forth guidelines for and significant
restrictions on investments in 'high-risk mortgage securities.' The Policy
Statement has been adopted by the Federal Reserve Board, the Office of the
Comptroller of the Currency, the FDIC and the Office of Thrift Supervision with
an effective date of February 10, 1992. The Policy Statement generally indicates
that a mortgage derivative product will be deemed to be high risk if it exhibits
greater price volatility than a standard fixed rate thirty-year mortgage
security. According to the Policy Statement, prior to purchase, a depository
institution will be required to determine whether a mortgage derivative product
that it is considering acquiring is high-risk, and if so, that the proposed
acquisition would reduce the institution's overall interest rate risk. Reliance
on analysis and documentation obtained from a securities dealer or other outside
party without internal analysis by the institution would be unacceptable. There
can be no assurance as to which classes of Securities will be treated as
high-risk under the Policy Statement. In addition, the National Credit Union
Administration has issued regulations governing federal credit union investments
which prohibit investment in certain specified types of securities, which may
include certain classes of Securities. Similar policy statements have been
issued by regulators having jurisdiction over other types of depository
institutions.
 
     There may be other restrictions on the ability of certain investors either
to purchase certain classes of Securities or to purchase any class of Securities
representing more than a specified percentage of the investors' assets. The
Sponsor will make no representations as to the proper characterization of any

class of Securities for legal investment or other purposes, or as to the ability
of particular investors to purchase any class of Securities under applicable
legal investment restrictions. These uncertainties may adversely affect the
liquidity of any class of Securities. Accordingly, all investors whose
investment activities are subject to legal investment laws and regulations,
regulatory capital requirements or review by regulatory authorities should
consult with their own
 
                                       88
<PAGE>
legal advisors in determining whether and to what extent the Securities of any
class constitute legal investments under SMMEA or are subject to investment,
capital or other restrictions, and whether SMMEA has been overridden in any
jurisdiction applicable to such investor.
 
                                USE OF PROCEEDS
 
     Unless otherwise specified in the related Prospectus Supplement,
substantially all of the net proceeds to be received from the sale of Securities
will be applied by the Sponsor to finance the purchase of, or to repay short-
term loans incurred to finance the purchase of, the Mortgage Loans underlying
the Securities or will be used by the Sponsor for general corporate purposes.
The Sponsor expects that it will make additional sales of securities similar to
the Securities from time to time, but the timing and amount of any such
additional offerings will be dependent upon a number of factors, including the
volume of mortgage loans purchased by the Sponsor, prevailing interest rates,
availability of funds and general market conditions.
 
                            METHODS OF DISTRIBUTION
 
     The Securities offered hereby and by the related Prospectus Supplements
will be offered in series through one or more of the methods described below.
The Prospectus Supplement prepared for each series will describe the method of
offering being utilized for that series and will state the public offering or
purchase price of such series and the net proceeds to the Sponsor from such
sale.
 
     The Sponsor intends that Securities will be offered through the following
methods from time to time and that offerings may be made concurrently through
more than one of these methods or that an offering of a particular series of
Securities may be made through a combination of two or more of these methods.
Such methods are as follows:
 
          1. By negotiated firm commitment or best efforts underwriting and
     public re-offering by underwriters;
 
          2. By placements by the Sponsor with institutional investors through
     dealers; and
 
          3. By direct placements by the Sponsor with institutional investors.
 
     In addition, if specified in the related Prospectus Supplement, a series of
Securities may be offered in whole or in part in exchange for the Mortgage Loans
(and other assets, if applicable) that would comprise the Mortgage Pool in

respect of such Securities.
 
     If underwriters are used in a sale of any Securities (other than in
connection with an underwriting on a best efforts basis), such Securities will
be acquired by the underwriters for their own account and may be resold from
time to time in one or more transactions, including negotiated transactions, at
fixed public offering prices or at varying prices to be determined at the time
of sale or at the time of commitment therefor. Such underwriters may be
broker-dealers affiliated with the Sponsor whose identities and relationships to
the Sponsor will be as set forth in the related Prospectus Supplement. The
managing underwriter or underwriters with respect to the offer and sale of a
particular series of Securities will be set forth on the cover of the Prospectus
Supplement relating to such series and the members of the underwriting
syndicate, if any, will be named in such Prospectus Supplement.
 
     In connection with the sale of the Securities, underwriters may receive
compensation from the Sponsor or from purchasers of the Securities in the form
of discounts, concessions or commissions. Underwriters and dealers participating
in the distribution of the Securities may be deemed to be underwriters in
connection with such Securities, and any discounts or commissions received by
them from the Sponsor and any profit on the resale of Securities by them may be
deemed to be underwriting discounts and commissions under the Securities Act of
1933, as amended. The Prospectus Supplement will describe any such compensation
paid by the Sponsor.
 
     It is anticipated that the underwriting agreement pertaining to the sale of
any series of Securities will provide that the obligations of the underwriters
will be subject to certain conditions precedent, that the underwriters will be
obligated to purchase all such Securities if any are purchased (other than in
connection with an underwriting on a best efforts basis) and that, in limited
circumstances, the Sponsor will indemnify the several underwriters and the
underwriters will indemnify the Sponsor against certain civil liabilities,
including liabilities under the Securities Act of 1933, as amended, or will
contribute to payments required to be made in respect thereof.
 
                                       89
<PAGE>
     The Prospectus Supplement with respect to any series offered by placements
through dealers will contain information regarding the nature of such offering
and any agreements to be entered into between the Sponsor and purchasers of
Securities of such series.
 
     The Sponsor anticipates that the Securities offered hereby will be sold
primarily to institutional investors. Purchasers of Securities, including
dealers, may, depending on the facts and circumstances of such purchases, be
deemed to be 'underwriters' within the meaning of the Securities Act of 1933, as
amended, in connection with reoffers and sales by them of Securities. Holders of
Securities should consult with their legal advisors in this regard prior to any
such reoffer or sale.
 
                                 LEGAL MATTERS
 
     Certain legal matters will be passed upon for the Sponsor by Dewey
Ballantine, New York, New York and by the office of the general counsel of the

Sponsor.
 
                             FINANCIAL INFORMATION
 
     The Sponsor has determined that its financial statements are not material
to the offering made hereby. However, any prospective purchaser who desires to
review financial information concerning the Sponsor will be provided by the
Sponsor upon request with a copy of the most recent financial statements of the
Sponsor.
 
     A Prospectus Supplement may contain the financial statements of the related
Credit Enhancer, if any.
 
                             ADDITIONAL INFORMATION
 
     This Prospectus, together with the Prospectus Supplement for each series of
Securities, contains a summary of the material terms of the applicable exhibits
to the Registration Statement and the documents referred to herein and therein.
Copies of such exhibits are on file at the offices of the Securities and
Exchange Commission in Washington, D.C., and may be obtained at rates prescribed
by the Commission upon request to the Commission and may be inspected, without
charge, at the Commission's offices.

                                    ANNEX I
         GLOBAL CLEARANCE, SETTLEMENT AND TAX DOCUMENTATION PROCEDURES
 
     Except in certain limited circumstances, the globally offered Securities
(the 'Global Securities') will be available only in book-entry form. Investors
in the Global Securities may hold such Global Securities through any of DTC,
CEDEL or Euroclear. The Global Securities will be tradeable 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 through CEDEL and Euroclear will
be conducted in the ordinary way in accordance with the normal rules and
operating procedures of CEDEL and Euroclear and in accordance with conventional
eurobond practice (i.e., seven calendar day settlement).
 
     Secondary market trading between investors through DTC will be conducted
according to DTC's rules and procedures applicable to U.S. corporate debt
obligations.
 
     Secondary cross-market trading between CEDEL or Euroclear and DTC
Participants holding Certificates will be effected on a delivery-against-payment
basis through the respective Depositaries of CEDEL and Euroclear (in such
capacity) and as DTC Participants.
 
     Non-U.S. holders (as described below) of Global Securities will be subject
to U.S. withholding taxes unless such holders meet certain requirements and
deliver appropriate U.S. tax documents to the securities clearing organizations
or their participants.
 
INITIAL SETTLEMENT
 
     All Global Securities will be held in book-entry form by DTC in the name of
Cede & Co. as nominee of DTC. Investors' interests in the Global Securities will
be represented through financial institutions 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 Depository
which in turn will hold such positions in their accounts as DTC Participants.
 
     Investors electing to hold their Global Securities through DTC will follow
DTC settlement practices. 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 the
securities custody accounts on the settlement date against payment in same-day
funds.
 
SECONDARY MARKET TRADING
 
     Since the purchaser determines the place of delivery, it is important to
establish at the time of the trade where both the purchaser's and seller's

accounts are located to ensure that settlement can be made on the desired value
date.
 
     Trading between DTC Participants.  Secondary market trading between DTC
Participants will be settled using the procedures applicable to prior home
equity loan asset-backed certificates 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.
 
     Trading between DTC, Seller and CEDEL or Euroclear Participants.  When
Global Securities are to be transferred from the account of a DTC Participant to
the account of a CEDEL Participant or a Euroclear Participant, the purchaser
will send instructions to CEDEL or Euroclear through a CEDEL Participant or
Euroclear Participant at least one business day prior to settlement. CEDEL or
Euroclear will instruct the Relevant Depository, 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
 
                                      A-1
<PAGE>
day of the following month. Payment will then be made by the Relevant Depository
to the DTC Participant's account against delivery of the Global Securities.
After settlement has been completed, the Global Securities will be credited to
the respective clearing system and by the clearing system, in accordance with
its usual procedures, to the CEDEL Participant's or Euroclear Participant's
account. The securities credit will appear the next day (European time) and the
cash debt will be back-valued to, and the interest on the Global Securities will
accrue from, the value date (which would be the preceding day when settlement
occurred in New York). If settlement is not completed on the intended value date
(i.e., the trade fails), the CEDEL or Euroclear cash debt will be valued instead
as of the actual settlement date.
 
     CEDEL Participants and Euroclear Participants will need to make available
to the respective clearing systems the funds necessary to process same-day funds
settlement. The most direct means of doing so is to preposition funds for
settlement, either from cash on hand or existing lines of credit, as they would
for any settlement occurring within CEDEL or Euroclear. Under this approach,
they may take on credit exposure to CEDEL or Euroclear until the Global
Securities are credited to their account 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 cleared the
overdraft when the Global Securities were credited to their accounts. However,
interest on the Global Securities would accrue from the value date. Therefore,
in many cases the investment income on the Global Securities earned during that

one-day period may substantially reduce or offset the amount of such overdraft
charges, although the result will depend on each CEDEL Participant's or
Euroclear Participant's particular cost of funds.
 
     Since the settlement is taking place during New York business hours, DTC
Participants can employ their usual procedures for crediting Global Securities
to the respective European Depository for the benefit of CEDEL Participants or
Euroclear Participants. The sale proceeds will be available to the DTC seller on
the settlement date. Thus, to the DTC Participants a cross-market transaction
will settle no differently than a trade between two DTC Participants.
 
     Trading between CEDEL or Euroclear Seller and DTC Purchaser.  Due to time
zone differences in their favor, CEDEL Participants and Euroclear Participants
may employ their customary procedures for transactions in which Global
Securities are to be transferred by the respective clearing system, through the
respective Depository, to a DTC 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 respective Depository, as appropriate, to credit the Global
Securities to the DTC Participant's account against payment. Payment will
include interest accrued on the Global Securities from and including the last
coupon payment to and excluding the settlement date on the basis of the actual
number of days in such accrual period and a year assumed to consist to 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. The
payment will then be reflected in the account of 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). In the event that the CEDEL Participant or Euroclear Participant have a
line of credit with its respective clearing system and elect to be in debt in
anticipation of receipt of the sale proceeds in its account, the back-valuation
will extinguish any overdraft incurred over that one-day period. If settlement
is not completed on the intended value date (i.e., the trade fails), receipt of
the cash proceeds in the CEDEL Participant's or Euroclear Participant's account
would instead be valued as of the actual settlement date.
 
     Finally, day traders that use CEDEL or Euroclear and that purchase Global
Securities from DTC Participants for delivery to CEDEL Participants or Euroclear
Participants should note that these trades would automatically fail on the sale
side unless affirmative action is 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 trade is reflected in their CEDEL or Euroclear
     accounts) in accordance with the clearing system's customary procedures;
 
                                      A-2
<PAGE>
          (b) borrowing the Global Securities in the U.S. from a DTC Participant
     no later than one day prior to settlement, which would give the Global
     Securities sufficient time to be reflected in their CEDEL or Euroclear
     account in order to settle the sale side of the trade; or
 

          (c) staggering the value dates for the buy and sell sides of the trade
     so that the value date for the purchase from the DTC Participant is at
     least one day prior to the value date for the sale to the CEDEL Participant
     or Euroclear Participant.
 
CERTAIN U.S. FEDERAL INCOME TAX DOCUMENTATION REQUIREMENTS
 
     A beneficial owner of Global Securities holding securities through CEDEL or
Euroclear (or through DTC if the holder has an address outside the U.S.) will be
subject to the 30% U.S. withholding tax that generally applies to payments of
interest (including original issue discount) on registered debt issued by U.S.
Persons (as defined below), 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 (as defined below) 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 (as defined below), including a non-U.S.
     corporation or bank with a U.S. branch, for which the interest income is
     effectively connected with its conduct of a trade or business in the United
     States, can obtain an exemption from the withholding tax by filing Form
     4224 (Exemption from Withholding of Tax on Income Effectively Connected
     with the Conduct of a Trade or Business in the United States).
 
          Exemption or reduced rate for non-U.S. Persons resident in treaty
     countries (Form 1001).  Non-U.S. Persons 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 tax will be imposed at that rate unless the filer
     alternatively files Form W-8. Form 1001 may be filed by Certificate Owners
     or their agent.
 
          Exemption for U.S. Persons (Form W-9).  U.S. Persons can obtain a
     complete exemption from the withholding tax by filing Form W-9 (Payer's
     Request for Taxpayer Identification Number and Certification).
 
          U.S. Federal Income Tax Reporting Procedure.  The 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.
 
     On April 22, 1996, the IRS proposed regulations relating to withholding,
backup withholding and information reporting that, if adopted in their current

form would, among other things, unify current certification procedures and forms
and clarify certain reliance standards. The regulations are proposed to be
effective for payments made after December 31, 1997 but provide that
certificates issued on or before the date that is 60 days after the proposed
regulations are made final will continue to be valid until they expire. Proposed
regulations, however, are subject to change prior to their adoption in final
form.
 
     The term 'U.S. Person' means (i) a citizen or resident of the United
States, (ii) a corporation, partnership or other entity organized in or under
the laws of the United States or any political subdivision thereof, (iii) an
estate that is subject to U.S. federal income tax regardless of the source of
its income or (iv) a trust if a court within the United States can exercise
primary supervision over its administration and at least one United States
fiduciary has 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 the Global Securities. Investors are
advised to consult their own tax advisors for specific tax advice concerning
their holding and disposing of the Global Securities.
