                                              Transfer Dates, will be approximately $500,000,000 with

                                              Mortgage Loans to be acquired by the Sponsor after the Closing Date.

                                              On the Closing Date, $46,807,367 (the "Group I Original
                                              Pre-Funded Amount") and $18,562,375 (the "Group II Original
                                              Pre-Funded Amount", together with the Group I Original
                                              Pre-Funded Amount, the "Original Pre-Funded Amounts") will be
                                              deposited with the Trustee and used to purchase the
                                              Subsequent Mortgage Loans for assignment to Group I or Group
                                              II, as applicable. The Subsequent Mortgage Loans, if
                                              available, will be originated by one or more of the
                                              Originators and sold by such Originator(s) to the Sponsor,
                                              which will then cause all right, title and interest of the
                                              Originators in each such Subsequent Mortgage Loan to be
                                              transferred to the Trust.  The Subsequent Mortgage Loans must
                                              conform to certain specified characteristics.

                                              The Sponsor will be obligated to cause the sale of the
                                              Subsequent Mortgage Loans to the Trust, and the Trust will be
                                              obligated, subject to the satisfaction of certain conditions
                                              described herein, to purchase such Subsequent Mortgage Loans
                                              from time to time (each such date of purchase, a "Subsequent
                                              Transfer Date") on or before January 16, 1998, subject to the
                                              availability thereof.  In connection with each purchase of
                                              Subsequent Mortgage Loans, the Trust will be required to pay
                                              a cash purchase price of 100% of the principal amount thereof
                                              from the applicable Pre-Funded Amount held in the Pre-Funding
                                              Account.  The Sponsor will designate as a cut-off date (each,
                                              a "Subsequent Cut-Off Date") the first day of the month in
                                              which Subsequent Mortgage Loans will be conveyed to the Trust
                                              during the Funding Period (as defined herein).  The Trust may
                                              purchase the Subsequent Mortgage Loans only from the Sponsor
                                              or one of its affiliates and not from any other person.  See
                                              "The  Mortgage Loan Pool" herein.

                                              With respect to the Statistic Calculation Pools, some
                                              amortization of the Mortgage Loans in such pools will occur
                                              prior to the Closing Date.  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 such characteristics as of the Closing Date
                                              in the final Mortgage Loan pools will vary somewhat from the
                                              statistical distribution of the Statistic Calculation Pools
                                              as presented in this Prospectus Supplement, although such
                                              variance will not be material.

                                              Unless otherwise noted, all statistical percentages in this
                                              Prospectus Supplement are measured by the aggregate principal
                                              balance of the related Mortgage Loans in the Statistic
                                              Calculation Pools.

                                              The Mortgage Loans will be predominantly home equity loans,
                                              i.e., loans used by obligors (each, a "Mortgagor") (x) to
                                              refinance an existing mortgage loan on more favorable terms,
                                              (y) to consolidate debt, or (z)  to obtain cash proceeds by

                                              Mortgaged Property.  The Mortgage Loans to be sold to the
                                              Trust by the Sponsor consisted, with respect to the Statistic
                                              Calculation Pools, of 10,724 Mortgages and the related Notes
                                              on one-to-four family residential properties, including
                                              investment properties (which may be condominiums, townhouses
                                              or homes in one-to-four family residences), located in 49
                                              states and the District of Columbia.  The Mortgage Loans are
                                              secured by Mortgages of which 95.70% by principal balance are
                                              first mortgages or deeds of trust and 4.30% by principal
                                              balance are secured by junior mortgages or deeds of trust.
                                              The Mortgage Loans are all closed-end mortgage loans in that
                                              the mortgagee is not required to make future advances
                                              thereunder.

                                              Less than 0.26% of the Mortgage Loans are insured by primary
                                              mortgage insurance policies.  There is no pool insurance
                                              insuring any of the Mortgage Loans.

                                              The Mortgage Loans are not guaranteed by the Sponsor, the

Pre-Funding Account                           On the Closing Date the Trustee, upon receipt thereof, will
                                              deposit the Original Pre-Funded Amounts in the Pre-Funding
                                              Account.  The Group I Original Pre-Funded Amount will be
                                              funded from the sale of the Group I Certificates and may be
                                              used to acquire Subsequent Mortgage Loans for assignment to
                                              Group I during the Funding Period (as defined below).  The
                                              Group II Original Pre-Funded Amount will be funded from the
                                              sale of the Group II Certificates and may be used to acquire
                                              Subsequent Mortgage Loans for assignment to Group II during
                                              the Funding Period.  Subsequent Mortgages may be transferred
                                              to the Trust during the period (the "Funding Period") from

                                              each Pre-Funded Amount is less than $100,000, (ii) the date

                                              the Group I Pre-Funded Amount, the "Pre-Funded Amounts") will
                                              be reduced by the principal balance of Subsequent Mortgage
                                              Loans purchased by the Trust and assigned to the applicable
                                              Group from time to time in accordance with the terms of the
                                              Pooling and Servicing Agreement.  The Sponsor expects that
                                              each of the Pre-Funded Amounts will be reduced to less than
                                              $100,000 by the January 1998 Payment Date.

Capitalized Interest Account                  On the Closing Date, the Trustee will be required to deposit
                                              a portion of the sale proceeds of the Certificates in an
                                              account (the "Capitalized Interest Account").  The respective
                                              amounts deposited therein will be used, as necessary, by the
                                              Trustee during the Funding Period to fund the negative
                                              arbitrage on the Pre-Funding Account monies.  Any amounts

                                              Certificates will generally receive principal distributions
                                              on each Payment Date which are based on principal
                                              collections, monies released from the Pre-Funding Account
                                              and Realized Losses (to the extent that Monthly Excess

                                              such Mortgage Loan Group.  Such accelerated principal will

                                              GROUP II-PRINCIPAL DISTRIBUTIONS.  On each Payment Date,
                                              principal will be distributed to the Owners of the Group II

                                              Certificates has been reduced to zero.

                                              The Group II Certificates are "concurrent pay" classes such

                                              and (b) thereafter will be zero.  For the Class A-9

                                              of the Owners of the Class A Group I Certificates consists

                                              enhancement only for Group I.

                                              GROUP II.  The Credit Enhancement provided for the benefit
                                              of the Owners of the Group II Certificates consists of the

                                              cross-collateralization feature of the Trust.  The Group
                                              II Certificates will have the benefit of certain levels of

                                              Application of Realized Losses (Group I and Group II). 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 Class R Certificates (both through
                                              the application of the Monthly Excess Interest Amount to
                                              fund such deficiency and through a reduction in the
                                              related Overcollateralization Amount).  In the case of
                                              Group I, any remaining deficiency after absorption by the
                                              Class R Certificates will be absorbed, second, by the
                                              Owners of the Class B-1 Certificates, third, by the Owners
                                              of the Class M-2 Certificates, and, fourth, by the Owners
                                              of the Class M-1 Certificates.  In the case of Group II,
                                              any remaining deficiency after absorption by the Class R
                                              Certificates will be covered by the Class A-8 and Class
                                              A-9 Insurance Policy to the extent of the Applied Realized
                                              Loss Amount for Group II.

                                              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 Monthly
                                              Excess Cashflow 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

                                              Mortgage Loan Group, after taking into account all

                                              the end of the related Remittance Period (i.e., if the
                                              level of overcollateralization is negative), such excess
                                              is an "Applied Realized Loss Amount" with respect to the
                                              related Group.  In the case of Group I, such an Applied
                                              Realized Loss Amount will be applied as a reduction in the

                                              Certificates in reverse order of seniority (i.e., first,
                                              against the Class B-1 Certificate Principal Balance until
                                              it is reduced to zero, second, against the Class M-2

                                              Balance until it is reduced to zero).  In the case of
                                              Group II, the Trustee will make a claim under the Class

                                              Applied Realized Loss Amount with respect to Group II. 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

                                              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

                                              third, the Class B-1 Certificates).  The source of funding
                                              of such payments will be the amount, if any, of the

                                              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 on the Mortgage Loans 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

                                              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

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

                                              and Payment Date.  The Targeted Overcollateralization
                                              Amount is initially (i.e., prior to the related Stepdown
                                              Date) $12,500,000 with respect to Group I and, with
                                              respect to Group II, an amount required by the Class A-8
                                              and Class A-9 Insurer.  Because 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, 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

                                              If, once the Targeted Overcollateralization Amount with

                                              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

                                              Certificates.  On each Payment Date, the Class A-8 and
                                              Class A-9 Insurer will be required to make available to

                                              "Net Available Distribution Amount" means, with respect to
                                              any Payment Date, the sum of (i) the amount on deposit in

                                              on such Payment Date.

                                              The Subordinate Certificates do not support the Group II
                                              Certificates and the Class A-8 and Class A-9 Insurance
                                              Policy does not guarantee any payments of principal and
                                              interest with respect to the Group I Certificates.

Nature of Class A-IO Certificates:            General Character as an Interest-Only Security.  As the
                                              owners of interest-only strip securities, the Owners of
                                              the Class A-IO Certificates will be entitled to receive
                                              monthly distributions only of interest, as described
                                              herein.  Because they will not receive any distributions
                                              of principal, the Owners of the Class A-IO Certificates
                                              will be affected by prepayments, liquidations and other
                                              dispositions (including optional redemptions described
                                              herein) of the Mortgage Loans in Group I to a greater
                                              degree than will the Owners of the other Classes of Group
                                              I Certificates.  In addition, the Notional Principal
                                              Balance applicable to interest calculations on the Class
                                              A-IO Certificates is (x) through the 30th Payment Date,
                                              the Class A-7 Certificate Principal Balance and (y)
                                              thereafter, zero.  Because the Class A-7 Certificates will
                                              amortize in accordance with the distribution of the Class
                                              A-7 Lockout Distribution Amount, the performance of the
                                              Class A-IO Certificates is likely to be more stable than
                                              if such Notional Principal Balance were calculated based
                                              on the amortization of the underlying Group I Mortgage
                                              Loans directly, and consequently, the yield sensitivity of
                                              such Certificates will only be impacted at extremely high
                                              prepayment rates.  In addition, since the Group I
                                              Statistic Calculation Pool contains 6,774 Mortgage Loans,
                                              the prepayment experience of any one of the Group I
                                              Mortgage Loans will not be material to an investor's
                                              overall return.

                                              In general, losses due to limitations, repurchases by the
                                              Master Servicer and other dispositions of the Group I
                                              Mortgage Loans from the Trust will have the same effect on
                                              the Owners of the Class A-IO Certificates as do
                                              prepayments of principal and are collectively referred to
                                              as "Prepayments."

                                              Because the yield to the Owners of the Class A-IO
                                              Certificates is more sensitive to rates of prepayment, it
                                              is advisable for potential investors in the Class A-IO
                                              Certificates to consider carefully, and to make their own
                                              evaluation of, the effect of any particular assumption
                                              regarding the rates and the

                                              timing of prepayments.  In general, when interest rates 
                                              decline, prepayments in a pool of receivables 
                                              such as the Group I Mortgage Loans will increase 
                                              as borrowers seek to refinance at lower
                                              rates.  Because, however, the amortization of the Class
                                              A-IO Certificates is tied to the Notional Principal
                                              Balance, and the Notional Principal Balance will amortize
                                              in accordance with the distribution of the Class A-7
                                              Lockout Distribution Amount, the prepayment scenarios
                                              described above are mitigated and the performance of the
                                              Class A-IO Certificates is expected to be more stable and
                                              the yield sensitivity of such Certificates will only be
                                              impacted at extremely high prepayment rates.  See
                                              "Prepayment and Yield Considerations -- Yield Sensitivity
                                              of the Class A-IO Certificates" herein for other factors
                                              which may also influence prepayment rates.

                                              Applicability of Credit Enhancement to the Class A-IO
                                              Certificates.  As described above under "Credit
                                              Enhancement," the Trust includes provisions which
                                              subordinate the distributions on the Subordinate
                                              Certificates and the Class R Certificates for each Payment
                                              Date for the purpose, inter alia, of funding the full
                                              amount used on each Class of the Class A Group I
                                              Certificates, including the Class A-IO Certificates, on
                                              each Payment Date.

                                              In general, the protection afforded by such subordination
                                              and overcollateralization features is for credit risk and
                                              not for prepayment risk.  These features do not guarantee
                                              or insure that any particular rate of prepayment is
                                              experienced by the Trust.  If the entire pool of Group I
                                              Mortgage Loans were to prepay in the initial month, with
                                              the result that the Owners of the Class A-IO Certificates
                                              receive only a single month's interest and thus suffer a
                                              nearly complete loss on their investments, no amounts
                                              would be available from the overcollateralization feature
                                              to mitigate such loss.

                                              Accrual of "Original Issue Discount."  The Class A-IO
                                              Certificates will be issued with "original issue discount"
                                              within the meaning of the Code.  As a result, in certain
                                              rapid prepayment environments the effect of the rules
                                              governing the accrual of original issue discount may
                                              require Owners of the Class A-IO Certificates to accrue
                                              original issue discount at a rate in excess of the rate at
                                              which distributions are received by such Owners.  See

                                              Advance will be reimbursable from any amounts in the

                                              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

                                              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.

distributions.  The subordination of the Subordinate Certificates relative to
the Class A Group I Certificates (and of the lower-ranking Classes of the
Subordinate Certificates to the higher-ranking Classes thereof) is intended to
enhance the likelihood of regular receipt by the Owners of such Class A Group I
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.

         Group I Subordination--Allocation of Losses to Subordinate
Certificates.  The rights of the Owners of each Class of Subordinate
Certificates to receive distributions of principal and interest with respect to
the Mortgage Loans will be subordinate to the rights of the Owners of the Class
A Group I 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 the Class B-1
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 the Class B-1
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.

         Special Risks Associated with the Class A-IO Certificates.  As the
owners of interest-only strip securities, the Owners of the Class A-IO
Certificates will be entitled to receive monthly distributions only of
interest, as described herein.  Because they will not receive any distributions
of principal, the Owners of the Class A-IO Certificates will generally be
affected by prepayments, liquidations and other dispositions (including
optional redemptions described herein) of the Mortgage Loans in Group I to a
greater degree than will the Owners of the other Classes of the Group I
Certificates.  Investors should note, however, that the Notional Principal
Balance applicable to interest calculations on the Class A-IO Certificates is
(x) through the 30th Payment Date, the Class A-7 Certificate Principal Balance
and (y) thereafter, zero.  Because the Class A-7 Certificates will amortize in
accordance with the distribution of the Class A-7 Lockout Distribution Amount,
the yield sensitivity of the Class A-IO Certificates is likely to be more
stable than if such Notional Principal Balance were calculated based on the
amortization of the underlying Group I Mortgage Loans directly.  Thus, the
yield sensitivity of such Certificates will only be impacted at extremely high
prepayment rates.

         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





                                      S-33
<PAGE>   34



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 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 "  -- 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, 5.73% 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.

         The Subsequent Mortgage Loans and the Pre-Funding Account.  If the
principal amount of eligible Mortgage Loans available during the Funding Period
and sold to the Trust is less than 100% of the respective Original Pre-Funded
Amounts, the Sponsor will have insufficient Subsequent Mortgage Loans to sell
to the Trust on the Subsequent Transfer Dates, thereby resulting in prepayments
of principal to Owners of one or more of Classes of Offered Certificates as
described herein.  See "Social, Economic and Other Factors" below.  Although no
assurance can be given, it is anticipated by the Sponsor that the principal
amount of Subsequent Mortgage Loans sold to the Trust will require the
application of substantially all amounts on deposit in Pre-Funding Account and
that there will be no material principal prepayment to the Owners of Offered
Certificates.

         Any conveyance of Subsequent Mortgage Loans is subject to the
following conditions, among others:  (i) each such Subsequent Mortgage Loan
must satisfy certain representations and warranties; (ii) the Sponsor will not
select such Subsequent Mortgage Loans in a manner that it believes is adverse
to the interests of the Owners of the Offered Certificates; (iii) the Sponsor
will deliver certain opinions of counsel with respect to the validity of the
conveyance of such Subsequent Mortgage Loans; (iv) with respect to Subsequent
Mortgage Loans to be assigned to Group II, the Class A-8 and Class A-9 Insurer
consents to such transfer; and (v) as of the Subsequent Cut-Off Date, the
Mortgage Loans at that time, including the Subsequent Mortgage Loans to be
conveyed to the Trust as of such





                                      S-34
<PAGE>   35



Subsequent Cut-Off Date, will satisfy the criteria set forth in the Pooling and
Servicing Agreement, as described under "The Mortgage Loan Pool -- Conveyance
of Subsequent Mortgage Loans" herein.

         Each Subsequent Mortgage Loan must satisfy the eligibility criteria
referred to above at the time of its addition.  However, Subsequent Mortgage
Loans may have been originated by the Originators or purchased by the Sponsor
using credit criteria different from those which were applied to the Initial
Mortgage Loans and may be of a different credit quality.  Therefore, following
the transfer of Subsequent Mortgage Loans, the aggregate characteristics of the
Mortgage Loans then held in Group I or Group II may vary from those of the
Initial Mortgage Loans.  See "The Mortgage Loan Pool -- Conveyance of
Subsequent Mortgage Loans" herein.

         Social, Economic and Other Factors.  The ability of the Trust to
invest in Subsequent Mortgage Loans is largely dependent upon social, economic
and other factors which may affect the ability of the Originators to originate
Subsequent Mortgage Loans for transfer on a Subsequent Transfer Date.  Economic
factors include interest rates, unemployment levels, the rate of inflation and
consumer perception of economic conditions generally.  However, the Sponsor is
unable to determine and has no basis to predict whether or to what extent
economic or social factors will affect the origination and the availability of
Subsequent Mortgage Loans.

         Developments Relating to Advanta Corp. During 1997.  Certain
developments have occurred during 1997 with respect to Advanta Corp., the
ultimate corporate parent of the Sponsor and of the Master Servicer.  The
consequences, if any, of such developments may positively, or may adversely,
affect the financial ability of the Sponsor and/or the Master Servicer to
perform their financial obligations, or to service the Mortgage Loan pool.  See
"The Sponsor and the Master Servicer - Recent Developments related to Advanta
Parent".

         Risk of Mortgage Loan Rates Reducing the Pass-Through Rate on the
Group II Certificates.  The calculation of the Pass-Through Rate on the Group
II Certificates is based upon (i) the value of an index (LIBOR) which is
different from the value of the indices applicable to the Mortgage Loans in
Group II as described under "The Mortgage Loan Pool -- Mortgage Loans -- Group
II" (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 Group II which are subject to periodic adjustment
caps, maximum rate caps, minimum rate floors, various resets and reset
frequencies.  94.42% of the Mortgage Loans by aggregate Principal Balance in
the Group II Statistic Calculation Pool adjust semi-annually based upon the
London interbank offered rate for six-month United States dollar deposits
("Six-Month LIBOR"); 0.88% adjust annually based upon 11th District Cost of
Funds Index ("COFI").  4.70% adjust annually based upon the one-year constant
maturity treasury (the "CMT"), whereas the Pass- Through Rate on the Group II
Certificates adjusts monthly based upon LIBOR as described under "Description
of the Certificates -- Calculation of LIBOR" herein, subject to the Group II
Available Funds Cap Rate (unless Supplemental Interest Amounts, the payment of
which is not rated, are paid in full).  Consequently, the interest which
becomes due on the Mortgage Loans in Group II (net of the Servicing Fee, the
Trustee Fee, the Premium 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 Group II Certificates during the related Accrual Period.  60.47%
of the Mortgage Loans by aggregate Principal Balance in the Group II Statistic
Calculation Pool are 2/28 Loans that provide for a fixed interest rate for a
period of approximately two years following origination.  11.50% of the
Mortgage Loans by aggregate Principal Balance in the Group II Statistic
Calculation Pool are 3/27 Loans that provide for a fixed interest rate for a
period of approximately three years following origination.  10.60% of the
Mortgage Loans by aggregate Principal Balance in the Group II Statistic
Calculation Pool 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, COFI and CMT Loans.  In particular, the
Pass-Through Rate on the Group II Certificates adjusts monthly, while the
interest rates of the Mortgage Loans in Group II adjust less frequently with
the result that the Group II Available Funds Cap Rate may limit increases in
the Pass-Through Rate on the Group II Certificates for extended periods in a
rising interest rate environment.  In addition, LIBOR, Six-Month LIBOR, COFI
and 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, COFI and CMT rise
during the same period, LIBOR may rise more rapidly than Six-Month LIBOR, COFI
or CMT.  Furthermore, if the Group II Available Funds Cap Rate determines the
Pass-Through Rate on the Group II Certificates for a Payment Date, the value of
the Group II Certificates will be temporarily or permanently reduced.

                             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 10,724 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 49
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.

         The Mortgage Loans will be required to satisfy the following criteria
as of the Initial 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 0.62% of the
aggregate principal balance of all Mortgage Loans as of the Initial Cut-Off
Date, may be 30-59 days delinquent).  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 10.40% 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.  A "simple interest" loan
provides that interest which has accrued to date is paid first and the
remaining payment is applied to reduce the unpaid principal balance.  An
"actuarial" loan provides for amortization of the loan over a series of fixed
level monthly installments.  95.70% of the Mortgage Loans are secured by first
lien mortgages on the related Mortgaged Properties and 4.30% 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 ("Group I" and "Group II", respectively, and each a
"Mortgage Loan Group").  Each of the Mortgage Loans contained in Group I 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 Group II 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 Group I Certificates represent undivided
ownership interests in all Mortgage Loans contained or to be contained in Group
I and the Group II Certificates represent undivided ownership interests in all
Mortgage Loans contained or to be contained in Group II.

         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 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 the Statistic Calculation Pools.  The Statistic Calculation Pools
reflect the Mortgage Loans acquired by the Sponsor through the Initial 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 Initial Cut-Off
Date.  These pools aggregated $391,100,496.44 with respect to Group I and
$353,220,751.29 with respect to Group II.  The Sponsor expects that the actual
aggregate principal balance of the Initial Mortgage Loans, as of the Closing
Date, plus the Subsequent Mortgage Loans, as of the related Subsequent Transfer
Dates, will be approximately $500,000,000.00 with respect to Group I and
approximately $400,000,000.00 with respect to Group II.  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 or
Subsequent Mortgage Loans to be acquired by the Sponsor after 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 Initial Mortgage Loan pools will vary somewhat from the
statistical distribution of such characteristics in the Statistic Calculation
Pools as presented in this Prospectus Supplement, although such variance will
not be material.

GROUP I

         The Mortgage Loans in the Group I Statistic Calculation Pool consist
of 6,774 Mortgage Loans under which the related Mortgaged Properties are
located in 49 states and the District of Columbia, as set forth herein.  Group
I had an aggregate principal balance of $391,100,496.44 and the minimum
principal balance of any of the Mortgage Loans in the Group I Statistic
Calculation Pool was $417.49, the maximum principal balance thereof was
$559,727.44 and the average principal balance of such Mortgage Loans was
approximately $57,735.53.  The Mortgage Rates on the Mortgage Loans in Group I
ranged from 6.83% to 18.99% per annum, and the weighted average Mortgage Rate
of such Mortgage Loans was 10.70% per annum.  The original term to stated
maturity of the Mortgage Loans in Group I ranged from 36 months to 360 months,
the remaining term to stated maturity ranged from 3 months to 360 months, the
weighted average original term to stated maturity was 248 months, the weighted
average remaining term to stated maturity was 247 months and the weighted
average seasoning was 1 month.  No Mortgage Loan in Group I had a stated
maturity later than December 20, 2027.  80.75% of the Mortgage Loans in Group I
by aggregate principal balance require monthly payments of principal that will
fully amortize the Mortgage Loans by their respective maturity dates, and
19.25% of such Mortgage Loans by aggregate principal balance are balloon loans.

         The weighted average CLTV of the Mortgage Loans included in Group I
was 74.60%.  The weighted average Junior Lien Ratio (as defined below) of the
Mortgage Loans in Group I was 35.05%; the weighted average LTV was 70.83%.
Approximately 92.56% of the Mortgage Loans in Group I by aggregate principal
balance were secured by first mortgages and approximately 7.44% 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 Group I Mortgage Loans and the
related Mortgaged Properties based upon the Group I Statistic Calculation Pool
as constituted at the opening of business on the Initial Cut-Off Date.

CONVEYANCE OF SUBSEQUENT MORTGAGE LOANS

         During the Funding Period, the Pooling and Servicing Agreement permits
the Trust to acquire $46,807,367 aggregate principal balance of Subsequent
Mortgage Loans for assignment to Group I and $18,562,375 aggregate principal
balance of Subsequent Mortgage Loans for assignment to Group II.  Accordingly,
the statistical characteristics of either Group will vary as of any Subsequent
Cut-Off Date upon the acquisition of the Subsequent Mortgage Loans which are
assigned to such Group.

                      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 (OTHER THAN THE CLASS
A-IO 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 Group I are 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 mortgage loans.  74.11% of the Mortgage Loans in the
Group I Statistic Calculation Pool by aggregate principal balance had
prepayment penalties.

<PAGE>   58



         All of the Mortgage Loans in Group II 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.
67.86% of the Mortgage Loans in the Group II Statistic Calculation Pool by
aggregate principal balance had prepayment penalties.

         The Final Scheduled Payment Dates for the Class A-6, Class A-7, Class
M-1, Class M-2 and Class B-1 Certificates have been calculated assuming that
the Mortgage Loan in the related Mortgage Loan Group having the latest maturity
amortizes according to its terms, plus one year.  The Final Scheduled Payment
Dates for the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5 and Class
A-8 Certificates have been calculated based on 0% CPR with no Monthly Excess
Cashflow used to make accelerated payments of principal to the owners of the
related Offered Certificates and on the assumption specified below in this
section.  If, on the 360th Payment Date, the Certificate Principal Balance of
the Class A-9 Certificates has not been reduced to zero (after taking into
account all principal distributions on such Payment Date), a draw may be made
on the Class A-8 and Class A-9 Insurance Policy to reduce the outstanding
Principal Balance of the Class A-9 Certificates to zero.

         "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 the
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.

         For the purpose of the tables below, it is assumed that:

         (i)     the Mortgage Loans consist of synthetic mortgage loans having
                 the characteristics set forth below,

         (ii)    the Closing Date is December 18, 1997,

         (iii)   distributions on the Certificates are made on the 25th day of
                 each month regardless of the

                 day on which the Payment Date actually occurs, commencing in
                 January, 1998 in accordance with the priorities described
                 herein,

         (iv)    all prepayments are repayments in full and include 30  days'
                 interest thereon,

         (v)     no early termination of the Trust occurs,

         (vi)    no Mortgage Loan is ever delinquent,

         (vii)   the assumed levels of one-month LIBOR, six-month LIBOR, and
                 CMT are 5.9687%, 5.9375% and 5.56%, respectively,

         (viii)  Offered Certificates have the respective pass-through rates
                 and original principal balances as set forth herein, and

         (ix)    all funds originally deposited in the Pre-Funding Account are
                 used to purchase the Subsequent Mortgage Loans on the Closing
                 Date.

</TABLE>

(1)      To Maturity
(2)      To 10% Call

         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.

         The actual characteristics and performance of the Mortgage Loans will
differ from the assumptions used in constructing the tables set forth above,
which only demonstrate how the Mortgage Loans may behave under varying





                                      S-73
<PAGE>   74
prepayment scenarios.  It is unlikely that the Mortgage Loans will prepay at
the same levels of CPR or in accordance with the Prepayment Assumptions.
Moreover, the varying remaining terms to maturity of the Mortgage Loans could
produce slower or faster principal payments then indicated in the foregoing
tables.

YIELD SENSITIVITY OF THE CLASS A-IO CERTIFICATES

         As the owners of interest-only strip securities, the Owners of the
Class A-IO Certificates will be entitled to receive monthly distributions only
of interest, as described herein.  Because they will not receive any
distributions of principal, the Owners of the Class A-IO Certificates will be
affected by prepayments, liquidations and other dispositions (including
optional redemptions described herein) of the Mortgage Loans in Group I to a
greater degree than will the Owners of the other Classes of Group I
Certificates.  In addition, the Notional Principal Balance applicable to
interest calculations on the Class A-IO Certificates is (x) through the 30th
Payment Date, the Class A-7 Certificate Principal Balance and (y) thereafter,
zero.  Because, however, the Class A-7 Certificates will amortize in accordance
with the distribution of the Class A-7 Lockout Distribution Amount, the
prepayment scenarios described above are mitigated and the performance of the
Class A-IO Certificates is expected to be more stable than if such Notional
Principal Balance were calculated based on the amortization of the underlying
Group I Mortgage Loans directly; consequently, the yield sensitivity of such
Certificates will only be impacted at extremely high prepayment rates.

PAYMENT LAG FEATURE OF GROUP I CERTIFICATES

         Pursuant to the Pooling and Servicing Agreement, interest on the Group
I Certificates (except the A-1 Certificates) accrues during the calendar month
immediately preceding the month in which the related Payment Date occurs.
Payment Dates occur on the 25th day of each month (or, if such day is not a
business day, on the next business day) commencing in January 1998.  Thus, the
effective yield to the Owners of the Group I Certificates (except the A-1
Certificates) will be below that otherwise produced by the related Pass-Through
Rate because distributions to Owners of the Group I Certificates in respect of
any given month will not be made until on or after the 25th day of the
following month.

                                USE OF PROCEEDS

         The Sponsor will cause the Trust to acquire the Mortgage Loans (other
than the Subsequent Mortgage Loans) concurrently with the sale of the Offered
Certificates.  The Pre-Funding Account and the Capitalized Interest Account
will be funded from a portion of the proceeds of 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 September 30, 1997 in excess of $6.7 billion.  Advanta Parent, through
its subsidiaries (including the Master Servicer) managed assets (including
mortgage loans) in excess of $20.8 billion as of September 30, 1997.  See "The
Sponsor and the Transferor" in the Prospectus.

         As of September 30, 1997, the Master Servicer and its subsidiaries
were servicing approximately 66,000 Mortgage Loans in the Owned and Managed
Servicing Portfolio representing an aggregate outstanding principal balance of
approximately $4.3 billion, and approximately 132,000 mortgage loans in the
Third-Party Servicing Portfolio representing an aggregate outstanding principal
balance of approximately $9.0 billion.  See "The Master Servicer" in the
Prospectus.

         As of September 30, 1997, the Sponsor or its affiliates have issued 33
issues of mortgage pass-through securities with an original balance of
approximately $6.2 billion.





                                      S-74
<PAGE>   75
         The Master Servicer may resign or be removed, 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 and of the Class A-8 and Class A-9
Insurer, which consent shall not be unreasonably withheld; provided, 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 Master Servicer, the Trustee will be required to serve as Master
Servicer.  If the Trustee is unable to obtain a qualifying bid and is prevented
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 the Class
A-8 and Class A-9 Insurer 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 expected to report
1997 results well below previous expectations.  Advanta Parent reported a loss
of $19.8 million for the first quarter of 1997.  The losses are attributed to a
number of factors, including increases in consumer bankruptcies and charge-offs
and lower receivables balances than originally anticipated in its credit card
business.

         On July 16, 1997, Advanta Parent reported net income of $5.4 million
for the second quarter of 1997, compared to net income of $45.1 million for the
second quarter of 1996.  On October 15, 1997, Advanta Parent reported net
income of $42.4 million for the third quarter of 1997, compared to net income
of $44.4 million for the third quarter of 1996.

         On June 30, 1997, purported shareholders of Advanta Parent, the
ultimate corporate parent of the Sponsor, the Affiliated Originators and the
Master Servicer, who are represented by a group of law firms filed a putative
class action complaint against Advanta Parent and several of its current and
former officers and directors in the United States District Court for the
Eastern District of Pennsylvania.  A second, similar complaint was filed in the
same court a few days later by a different group of purported Advanta Parent
shareholders and a different group of  law firms.  Both complaints allege that
Advanta Parent made misrepresentations in certain of its public filings and
statements in violation of the Securities Exchange Act of 1934.  The complaints
seek damages of an unspecified amount.  Advanta Parent believes the complaints
are without merit and will vigorously defend itself against the actions.  On
August 25, 1997, a cardholder of Advanta Parent instituted a putative class
action complaint against Advanta Parent and certain of its subsidiaries,
including Advanta National Bank, one of the Affiliated Originators, in the
Delaware Superior Court for New Castle County.  Subsequently, on September 8,
10, and 12 and on October 2, 1997, similar actions were filed in the Orange
County California Superior Court, the United States District Court for the
Eastern District of Tennessee, Delaware Superior Court and the Circuit Court of
Covington County, Alabama, respectively.  The complaints allege that cardholder
accounts in a specific program were improperly repriced to a higher percentage
rate of interest.  The complaints assert various violations of federal and
state law with respect to such repricings, and each seeks damages of an
unspecified amount.  Advanta Parent believes that the complaints are without
merit and will vigorously defend against the actions. The program at issue
comprises a very small portion of Advanta Parent's consumer credit card
receivables.

         On October 28, 1997, Advanta Parent announced that it had reached a
definitive agreement under which Fleet Financial Group, Inc. ("Fleet") will
acquire Advanta Parent's consumer credit card business (including certain
assets and liabilities of Advanta National Bank, one of the Affiliated
Originators, relating to the consumer credit card business) and will combine it
with Fleet's consumer credit card business (the "Transaction").  Advanta Parent
will continue to operate its mortgage and business services companies,
including the Sponsor, the Affiliated Originators and the Master Servicer.

         Advanta Parent intends to seek shareholder approval and the
Transaction is subject to regulatory approval.  The Transaction, which is
expected to close by late 1997 or early 1998, is anticipated to have a total
value to Advanta Parent of approximately $1.3 billion, including an after tax
gain of approximately $500 million.

         Advanta Parent also announced that it intends to make a tender offer
to repurchase between $750 to $850 million of its common stock in 1998,
following the closing of the Transaction.  Following the tender offer, it is
expected that Advanta Parent will have a book value of approximately $650
million.

         Advanta Parent has reported that its overall charge-off rate on all
managed receivables (for which the mortgage loan portfolio represented
approximately 27% at September 30, 1997), for the nine months ended at
September 30, 1997, was 5.4%, compared to 3.0% for the same period of 1996.
Advanta Parent has further reported that its overall delinquency ratio (30 days
or more) for all managed receivables at September 30, 1997 was 5.7%, compared
to 4.2% at September 30, 1996.

         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 defective Mortgage Loans and
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.

         This Prospectus Supplement contains forward-looking statements,
including but not limited to projections of future earnings, that are subject
to certain risks and uncertainties that could cause actual results to differ
materially from those projected.  Significant risks and uncertainties include:
Advanta Parent and its subsidiaries' managed net interest margin, which in turn
is affected by Advanta Parent and its subsidiaries' success in originating new
credit card accounts, the receivables volume and initial pricing of new
accounts, the impact of repricing existing accounts and account attrition, the
mix of account types and interest rate fluctuations; the level of
delinquencies, customer bankruptcies, and charge-offs; and the amount and rate
of growth in Advanta Parent and its subsidiaries' expenses.  Advanta Parent and
its subsidiaries' earnings also may be significantly affected by factors that
affect consumer debt, competitive pressures from other providers of financial
services, the effects of governmental regulation, the amount and cost of
financing available to Advanta Parent and its subsidiaries, the difficulty or
inability to securitize Advanta Parent and its subsidiaries' receivables and
the impact of the ratings on debt of Advanta Parent and its subsidiaries.
Additional risks that may affect Advanta Parent and its subsidiaries' future
performance are set forth in "Risk Factors" in the Prospectus and in this
Prospectus Supplement and in other filings with the Securities and Exchange
Commission.

                        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 & Co., the nominee of
DTC.  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 (other than the Class A-IO
Certificates) shall evidence the right to receive on each Payment Date the
related Class Distribution Amount for such class of Offered Certificates, in
each





                                      S-76
<PAGE>   77
case until the related Certificate Principal Balance has been reduced to zero.
The Class A-IO Certificates shall evidence the right to receive interest
payments only.  The Owners of the 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 Certificate Account. See "Description of the Securities
- -- Payments on Mortgage Loans" 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 Certificate 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, Compensating Interest and
the proceeds of any liquidation of the Trust Estate relating to the Mortgage
Loans, 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."

         "Substitution Amounts" are amounts delivered in connection with a
qualified substitute Mortgage Loan, as described in the Pooling and Servicing
Agreement.

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 "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





                                      S-77
<PAGE>   78
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 the Prospectus.

         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.





                                      S-78
<PAGE>   79
         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
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 its relevant rules and procedures and
subject to the





                                      S-79
<PAGE>   80
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, the Class A-8 and Class A-9
Insurer 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 January 26, 1998, 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 (other than the Class A-IO Certificates) shall 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.  The Class A-IO Certificates shall
be entitled to receive Current Interest and any Interest Carry Forward Amount,
but shall not receive any Principal Distribution Amounts.  Distributions will
be made in immediately available funds to Owners of the 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 Entry Registration of the 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





                                      S-80
<PAGE>   81
balance of such Certificate as of the Closing Date by the Certificate Principal
Balance for the related Class of the Offered Certificates as of the Closing
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 Master Servicer, together with any Substitution Amount and any Loan
Purchase Price amount, (ii) the proceeds of any liquidation of the Trust Estate
along with (iii) amounts transferred from the Capitalized Interest Account and
the Pre-Funding Account.

         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 the related Mortgage Loan Group will be distributed in the following
order of priority:

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

         Second, with respect to Group II, the Premium then due to the Class
         A-8 and Class A-9 Insurer;

         Third, 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;

         Fourth, with respect to Group I, to the extent of the Interest Amount
         Available with respect to Group I then remaining, to the Owners of the
         Class M-1 Certificates, the Class M-1 Current Interest;

         Fifth, with respect to Group I, to the extent of the Interest Amount
         Available with respect to Group I then remaining, to the Owners of the
         Class M-2 Certificates, the Class M-2 Current Interest;

         Sixth, with respect to Group I, to the extent of the Interest Amount
         Available with respect to Group I then remaining, to the Owners of the
         Class B-1 Certificates, the Class B-1 Current Interest; and

         Seventh, 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:  GENERAL.  The Group I Certificates and the Group II
Certificates will generally receive principal distributions on each Payment
Date which are based on principal collections, monies released from the
Pre-Funding Account and Realized Losses, with respect to the related Mortgage
Loan Group.  In addition, the overcollateralization feature of the Trust
results in accelerated payments of principal with respect to each Mortgage Loan
Group to achieve, and thereafter maintain, a specialized level of
overcollateralization with respect to such Mortgage Loan Group.  Such
accelerated principal will generally be funded from excess interest with
respect to the related Mortgage Loan Group.

         GROUP II-PRINCIPAL DISTRIBUTIONS.  On each Payment Date, principal
will be distributed to the Owners of the Group II Certificates in an amount
equal to the Group II Principal Distribution Amount, in accordance with the
"concurrent pay" allocation percentages until the Certificate Principal Balance
of each such Class of Group II Certificates has been reduced to zero.





                                      S-81
<PAGE>   82
         The Group II Certificates are "concurrent pay" classes such that the
Owners of each such Class receives a fixed allocation percentage of the Group
II Principal Distribution Amount until the Certificate Principal Balance of the
Class A-8 Certificates has been reduced to zero.  Once the Class A-8
Certificates have been reduced to zero, 100% of the Group II Principal
Distribution Amount shall be paid to the Class A-9 Certificates.  For the Class
A-8 Certificates, such allocated percentage (the "Class A-8 Principal
Percentage") shall be (a) 37.5%, until the Class A-8 Certificate Principal
Balance has been reduced to zero, and (b) thereafter will be zero.  For the
Class A-9 Certificates, such allocated percentage (the "Class A-9 Principal
Percentage") shall be 100.00% minus the Class A-8 Principal Percentage;
provided, however, that on any Payment Date on which the Overcollateralization
Amounts related to Group II is zero and the Class A-8 and Class A-9 Insurance
Policy is not in effect, any amounts of principal payable to the Owners of the
Group II Certificates on such Payment Date shall be distributed pro rata and
not in accordance with the "concurrent pay" allocation percentages.

         GROUP I-PRINCIPAL DISTRIBUTIONS.  With respect to Group I and on each
Payment Date (a) before the Stepdown Date with respect to Group I or (b) with
respect to which a Group I Delinquency Trigger Event is in effect, the Owners
of the Class A Certificates (other than the Class A-IO Certificates) will be
entitled to receive payment of 100% of the Principal Distribution Amount with
respect to Group I for such Payment Date as follows:  first, to the Owners of
the Class A-7 Certificates, the Class A-7 Lockout Distribution Amount and then
to the Owners of the Class A Group I Certificates (other than the Class A-7
Certificates), in sequential order until the Certificate Principal Balance of
each such Class of Class A Group I Certificates has been reduced to zero.

         With respect to Group I and on each Payment Date (a) on or after the
Stepdown Date with respect to Group I and (b) as long as a Group I Delinquency
Trigger Event is not in effect and is not continuing, the Owners of all Classes
of the Group I Certificates (other than the Class A-IO 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 Group I as follows:

                 First, the lesser of (x) the Group I Principal Distribution
         Amount and (y) the Class A Principal Distribution Amount with respect
         to Group I shall be distributed to the Owners of the Class A-7
         Certificates, in an amount equal to the Class A-7 Lockout Distribution
         Amount, with the remainder paid to the Owners of the Class A Group I
         Certificates (other than the Class A-7 Certificates), in sequential
         order until the Certificate Principal Balance of each such Class of
         Class A Group I Certificates has been reduced to zero;

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

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

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

                 Fifth, the lesser of (x) any amount of the Group I Principal
         Distribution Amount remaining after making all of the distributions in
         clauses First, Second, Third and Fourth above and (y) (1) if no Group
         I Cumulative Realized Loss Trigger Event is in effect, the positive
         difference, if any, of (A) $2,500,000 minus (B) the Targeted
         Overcollateralization Amount (disregarding clause (y)(a)(ii) of the
         definition of Targeted Overcollateralization Amount relating to Group
         I) for Group I for such Payment Date or (2) if a Group I Cumulative
         Loss Trigger Event is in effect, the positive difference, if any, of
         (A) the Targeted Overcollateralization Amount for Group I for the
         immediately preceding Payment Date minus (B) the Targeted
         Overcollateralization Amount (disregarding clause (y)(c) of the
         definition of Targeted

<PAGE>   83
         Overcollateralization Amount for Group I) for Group I for such Payment
         Date shall, in either case (1) or (2), be applied as a payment of
         principal with respect to the Subordinate Certificates in reverse
         order of seniority (ie., first to the Class B-1 Certificates, second
         to the Class M-2 Certificates, third to the Class M-1 Certificates and
         fourth, to the Class A Group I Certificates) until their respective
         Certificate Principal Balances have been reduced to zero; and

                 Sixth, any amount of the Group I Principal Distribution Amount
         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 Amounts with respect to Group I and shall
         be applied as described below under "Credit Enhancement--Application
         of Monthly Excess Cashflow Amounts."

The Class A Group I Certificates (other than the Class A-7 Certificates and the
Class A-IO Certificates) are "sequential pay" classes such that the Owners of
the Class A-6 Certificates will receive no payments of principal until the
Class A-5 Certificate Principal Balance has been reduced to zero, the Owners of
the Class A-5 Certificates will receive no payments of principal until 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 and the Overcollateralization
Amount related to Group I is zero, any amounts of principal payable to the
Owners of the Class A Group I Certificates on such Payment Date shall be
distributed pro rata and not sequentially.

         Notwithstanding the foregoing, in the event that, on any Payment Date,
the Certificate Principal Balance of all of the Class A Group I Certificates is
zero, all amounts of principal that would have been distributed to such Class A
Group I Certificates on such Payment Date will be distributed to the
Subordinate Certificates sequentially in the following order:  first, to the
Class M-1 Certificates until the Certificate Principal Balance of the Class M-1
Certificates has been reduced to zero, second, to the Class M-2 Certificates
until the Certificate Principal Balance of the Class M-2 Certificates has been
reduced to zero, and third, to the Class B-1 Certificates until the Certificate
Principal Balance of the Class B-1 Certificates has been reduced to zero.

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 Group II Certificates and the
Class A-1 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 Telerate Page
3750 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; Telerate
Page 3750 means the display page so designated on the Dow Jones Telerate
Service (or such other page on that service for the purpose of displaying
comparable rates or prices); and "Reference Banks" means four leading banks
selected by the Master Servicer 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 Telerate Page 3750
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 Group II Certificates and the Class A-1 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 such Certificates shall be the arithmetic mean of such offered quotations
(rounded upwards if necessary to the nearest 1/100,000 of 1% (0.0000001), with
five one-millionths of a percentage point rounded upward, of all such
quotations.

         (b)  If on such Interest Determination Date fewer than two Reference
Banks provide such offered quotations, LIBOR for the related Accrual Period for
such Certificates shall be the rate for that day will be the arithmetic mean,
rounded upward, if necessary, to the nearest 1/100,000 of 1% (0.0000001), with
five one-





                                      S-83
<PAGE>   84
millionths of a percentage point rounded upward, of the offered per annum rates
that one or more leading banks in New York City, selected by the Indenture
Trustee, are quoting as of approximately 11:00 a.m., New York City time, on
such LIBOR Determination Date to leading European banks for United States
dollar deposits for the Index Maturity; provided that if the banks selected as
aforesaid are not quoting as mentioned in this sentence, LIBOR in effect for
the applicable Interest Period will be LIBOR in effect for the previous
Interest Period.

         The establishment of LIBOR on each Interest Determination Date by the
Trustee and the Trustee's calculation of the rate of interest applicable to
such 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

         GROUP I.  The Credit Enhancement provided for the benefit of the
Owners of the Class A Group I Certificates consists of the subordination of the
Subordinate Certificates, the priority of application of Realized Losses, the
application of the Group I Monthly Excess Cashflow Amounts and the
cross-collateralization feature of the Trust.

         GROUP II.  The Credit Enhancement provided for the benefit of the
Owners of the Group II Certificates consists of the Class A-8 and Class A-9
Insurance Policy, the application of the Group II Monthly Excess Cashflow
Amounts and the cross-collateralization feature of the Trust.  The Group II
Certificates will have the benefit of certain levels of overcollateralization
as required by the Class A-8 and Class A-9 Insurer.

         Application of Realized Losses (Group I and Group II).  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 Class R Certificates (both through the application of
the Monthly Excess Interest Amount to fund such deficiency and through a
reduction in the related Overcollateralization Amount).  In the case of Group
I, any remaining deficiency after absorption by the Class R Certificates will
be absorbed, second, by the Owners of the Class B-1 Certificates, third, by the
Owners of the Class M-2 Certificates, and, fourth, by the Owners of the Class
M-1 Certificates. In the case of Group II, any remaining deficiency will be
covered by the Class A-8 and Class A-9 Insurance Policy to the extent of the
Applied Realized Loss Amount.

         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.





                                      S-84
<PAGE>   85
         If, on any Payment Date and with respect to either Mortgage Loan
Group, after taking into account all Realized Losses experienced with respect
to such Mortgage Loan Group 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 Certificates on such Payment
Date, the Aggregate Certificate Principal Balance with respect to the related
Group exceeds the aggregate Principal Balance of the Mortgage Loans in the
related Group as of the end of the related Remittance Period (i.e., if the
level of overcollateralization is negative), such excess is an "Applied
Realized Loss Amount" with respect to the related Group.  In the case of Group
I, such an Applied Realized Loss Amount will be applied as a reduction in the
Certificate Principal Balance of the Subordinate Certificates in reverse order
of seniority (i.e., first against the Class B-1 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). In the case of Group II, the
Trustee will make a claim under the Class A-8 and Class A-9 Insurance Policy
with respect to an Applied Realized Loss Amount with respect to Group II.  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-1
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 Subordinate
Certificates on such Payment Date.

         Application of Monthly Excess Cashflow Amounts --
Overcollateralization Mechanics (Group I and Group II). 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 for such
Mortgage Loan Group and Payment Date.  The Targeted Overcollateralization
Amount is initially (i.e., prior to the related Stepdown Date) $12,500,000 with
respect to Group I and with respect to Group II, an amount required by the
Class A-8 and Class A-9 Insurer.  Because 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, 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 related Stepdown Date, the Targeted
Overcollateralization Amount with respect to Group I and Group II,
respectively, is permitted to decrease or "step-down" below their initial
levels (which, in the case of Group I is $12,500,000 and which, in the case of
Group II, is an amount required by the Class A-8 and Class A-9 Insurer) to
levels equal to specified percentages (which in the case of Group I is 5.00% of
the then current aggregate





                                      S-85
<PAGE>   86
outstanding Principal Balance of the Group I Mortgage Loans, and which, in the
case of Group II is a level required by the Class A-8 and Class A-9 Insurer,
and subject to a floor of $2,500,000 for Group I and, with respect to Group II,
an amount required by the Class A-8 and Class A-9 Insurer); provided, further,
that in the case of Group I, if a Group I Delinquency Trigger Event or a Group
I Cumulative Realized Loss Trigger Event is then in effect, the Targeted
Overcollateralization Amount for Group I shall be at the level set forth in the
definition thereof.  If the Targeted Overcollateralization Amount with respect
to 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
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.

         A.  On any Payment Date, the sum of the Group I Monthly Excess
Interest Amount and the Group I Overcollateralization Release Amount is the
Group I Monthly Excess Cashflow Amount, which is required to be applied in the
following order of priority on such Payment Date:

(1)      to fund the remaining Class A Interest Carry Forward Amount, if any,
         with respect to Group I;

(2)      to fund the Overcollateralization Deficiency, if any, for such Payment
         Date with respect to Group I;

(3)      to fund the Class M-1 Interest Carry Forward Amount, if any;

(4)      to fund the Class M-1 Realized Loss Amortization Amount for such
         Payment Date, if any;

(5)      to fund the Class M-2 Interest Carry Forward Amount, if any;

(6)      to fund the Class M-2 Realized Loss Amortization Amount for such
         Payment Date, if any;

(7)      to fund the Class B-1 Interest Carry Forward Amount, if any;

(8)      to fund the Class B-1 Realized Loss Amortization Amount for such
         Payment Date, if any;

(9)      to fund any amounts with respect to Group II listed in clauses B(1),
         (2) and (3) below for such Payment Date to the extent that such
         amounts have not been funded in full through the application of Group
         II Monthly Excess Cashflow Amount on such Payment Date;

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

(11)     to fund a distribution to Owners of the Class R Certificates.

         B.  On any Payment Date, the sum of the Group II Monthly Excess
Interest Amount and the Group II Overcollateralization Release Amount is the
Group II Monthly Excess Cashflow Amount, which is required to be applied in the
following order of priority on such Payment Date:

(1)      to fund any remaining Class A Interest Carry Forward Amount, if any,
         with respect to Group II;

(2)      to reimburse the Class A-8 and Class A-9 Insurer for prior,
         unreimbursed Insured Payments, subject to certain limits;

(3)      to fund the Overcollateralization Deficiency, if any, for such Payment
         Date with respect to Group II;

(4)      to reimburse the Class A-8 and Class A-9 Insurer for any amounts due
         and owing to the Class A-8 and Class A-9 Insurer under the Insurance
         Agreement;





                                      S-86
<PAGE>   87
(5)      to fund any amounts with respect to Group I listed in clauses A(1)
         through A(8) above for such Payment Date to the extent that such
         amounts have not been funded in full through the application of Group
         I Monthly Excess Cashflow Amounts on such Payment Date;

(6)       to the Master Servicer to the extent of any unreimbursed Delinquency
         Advances or Servicing Advances including Nonrecoverable Delinquency
         Advances and Nonrecoverable Servicing Advances;

(7)      to make payment of any Supplemental Interest Amount then due to the
         Owners of the Group II Certificates, or otherwise to fund a
         distribution to the Owners of the Class R Certificates; and

(8)      to fund a distribution to Owners of the Class R Certificates.

         Subordination of Subordinate Certificates (Group I).  The rights of
the Owners of the Subordinate Certificates and the Class R Certificates to
receive distributions with respect to the Mortgage Loans in Group I will be
subordinated, to the extent described herein, to such rights of the Owners of
the Class A Group I Certificates.  This subordination is intended to enhance
the likelihood of regular receipt by the Owners of the Class A Group I
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 Group I.

         The protection afforded to the Owners of the Class A Group I
Certificates by means of the subordination of the Subordinate Certificates and
the Class R Certificates will be accomplished by the preferential right of the
Owners of the Class A Group I Certificates to receive, prior to any
distribution being made on a Payment Date in respect of such Subordinate
Certificates and the Class R Certificates, the amounts of interest due them and
principal available for distribution on such Payment Date, and, if necessary,
by the right of the Owners of the Class A Group I Certificates to receive
future distributions of amounts that would otherwise be payable to the Owners
of such Subordinate Certificates and the Class R Certificates.

         In addition, the rights of the Owners of the Class M-2, Class B-1 and
Class R Certificates to receive distributions will be subordinated, to the
extent described herein, to such rights of the Owners of the Class A Group I
Certificates and Class M-1 Certificates.  This subordination is intended to
enhance the likelihood of regular receipt by the Owners of the Class A Group I
Certificates and the 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-1 and the Class R Certificates
to receive distributions will be subordinated in the same manner to such rights
of the Owners of the Class A Group I Certificates, Class M-1 and Class M-2
Certificates and the rights of Owners of the Class R Certificates to receive
distributions will be subordinated in the same manner to such rights of the
Owners of the Group I Certificates.

         The Class A-8 and Class A-9 Insurance Policy.  The Sponsor will obtain
a certificate guaranty insurance policy (the "Class A-8 and Class A-9 Insurance
Policy"), with respect to the Class A-8 and Class A-9 Certificates, which is
noncancelable, in favor of the Trustee on behalf of the Owners of the Group II
Certificates.  On each Payment Date, the Class A-8 and Class A-9 Insurer will
be required to make available to the Trustee the amount, if any, by which the
Group II Required Distributions exceeds the Net Available Distribution Amount
as of such Payment Date.  The Class A-8 and Class A-9 Insurance Policy does not
guarantee to Owners of the Class A-8 Certificates and Class A-9 Certificates
any specified rate of Prepayments.  See "The Class A-8 and Class A-9 Insurance
Policy", "The Class A-8 and Class A-9 Insurer" and "Credit Enhancement" herein
and "Description of Credit Enhancement" in the Prospectus.

         The Certificate Principal Balance of any Class of the Class A
Certificates (except the Class A-IO Certificates), is the Original Certificate
Principal Balance of such Class as reduced by all amounts actually distributed
to the Owners of such Class of Class A Certificates on all prior Payment Dates.

                      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 and on each Subsequent
Transfer Date, the Sponsor will cause the Trust to acquire the Mortgage Loans.
The Trust will issue the Offered Certificates to the Owners thereof on the
Closing Date.

         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 Certificate 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, (v) Net Liquidation Proceeds with respect to any
Liquidated Loan and (vi) proceeds from the liquidation of the Trust
(collectively, the "Trust Estate").

SALE OF MORTGAGE LOANS

         On the Closing Date and each Subsequent Transfer 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 and each Subsequent Transfer 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 or the related
Subsequent Transfer Date (collectively 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 Initial Cut-Off Date or the
Subsequent Cut-Off Date, as the case may be.

         In connection with the sale of the Mortgage Loans on the Closing Date
or related Subsequent Transfer 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 or related Subsequent
Transfer 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 the related Subsequent
Transfer 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 and the Class A-8 and Class A-9 Insurer an
acceptable





                                      S-89
<PAGE>   90
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.

SUBSEQUENT MORTGAGE LOANS

         Pursuant to the Pooling and Servicing Agreement, following the Closing
Date, the Trust will be permitted to purchase the Subsequent Mortgage Loans
from time to time on or before January 16, 1998, subject to the availability of
Subsequent Mortgage Loans originated on or before such date by one or more
Originators, and acquired by the Sponsor from such Originator(s) for subsequent
sale to the Trust.  The aggregate principal amount of Subsequent Mortgage Loans
which may be acquired by the Trust and assigned to Group I is the Group I
Original Pre-Funded Amount.  The aggregate principal amount of Subsequent
Mortgage Loans which may be acquired by the Trust and assigned to Group II is
the Group II Original Pre-Funded Amount.  In connection with each purchase of
Subsequent Mortgage Loans, the Trust will be required to pay to the Sponsor a
cash purchase price of 100% of the principal amount thereon from the applicable
Pre-Funded Amount held in the Pre-Funding Account.  The Sponsor will designate
as a Subsequent Cut-Off Date the first day of the month in which Subsequent
Mortgage Loans will be conveyed to the Trust during the Funding Period.  The
Trust may purchase the Subsequent Mortgage Loans only from the Sponsor or one
of its affiliates and not from any other person.

be construed in accordance with and governed by the laws of the State of New
York applicable to agreements made and to be performed therein.

TERMINATION OF THE TRUST

unless such acceleration is at the sole option of the Class A-8 and Class A-9
Insurer.

         Notwithstanding the foregoing paragraph, the Class A-8 and Class A-9
Insurance Policy does not cover shortfalls, if any, attributable to the
liability of the Trust or the Trustee for withholding taxes, if any (including
interest and penalties in respect of any such liability), any prepayment
penalty or other accelerated payment which at any time may become due on or
with respect to any Insured Obligation, other than at the sole option of the
Class A-8 and Class A-9 Insurer, nor against any risk other than Nonpayment,
including failure of the Trustee to make any payment due the Holders of the
Insured Obligations.

         The Class A-8 and Class A-9 Insurer will pay any Insured Payment that
is a Preference Amount on the Business Day following receipt on a Business Day

and such other documentation as is reasonably required by the Class A-8 and
Class A-9 Insurer, such documentation being in a form satisfactory to the Class
A-8 and Class A-9 Insurer, provided that if such documents are received after
12:00 noon New York City time on such Business Day, they will be deemed to be
received on the following Business Day.

         Insured Payments due under the Class A-8 and Class A-9 Insurance
Policy unless otherwise stated therein will be disbursed by the Class A-8 and
Class A-9 Insurer to the Trustee on behalf of the Holders by wire transfer of
immediately available funds in the amount of the Insured Payment.

         As used herein, the following terms shall have the following meanings:

         "Deficiency Amount" means the excess, if any, of Required Payments

Payment Date on which Insured Amounts are due or, with respect to an Insured
Payment which is a Preference Amount, the business day on which the required
documentation referred to above has been received by the Class A-8 and Class
A-9 Insurer.

         "Holder" shall mean any person who is the registered owner or
beneficial owner of any Insured Obligation.

         "Insured Amounts" shall mean, with respect to any Payment Date, the
Deficiency Amount (including any amounts paid in respect of an Insufficiency
Amount) for such Payment Date.

         "Insured Obligations" shall mean the Class A-8 Certificates and the
Class A-9 Certificates.

         "Insured Payments" shall mean, the aggregate amount actually paid by
the Class A-8 and Class A-9 Insurer to the Trustee in respect of (i) Insured
Amounts for a Payment Date and (ii) Preference Amounts for any given Business
Day.

         "Net Available Distribution Amount" means, with respect to any Payment
Date, the sum of (i) the amount on deposit in the Certificate Account on such
Payment Date with respect to Group II (including any such amounts transferred

Class A-8 and Class A-9 Insurer, plus (ii) any Monthly Excess Cashflow
available from Group I.

         "Nonpayment" shall mean, with respect to any Distribution Date, a
Deficiency Amount owing in respect of such Distribution Date.

         "Notice" means the notice sent in writing by telecopy, substantially
in the form of Exhibit A attached to the Certificate Insurance Policy, from the
Trustee specifying the Insured Amount which shall be due and owing on the
applicable Distribution Date.

         "Preference Amount" means any payment of principal or interest on an
Insured Obligation which has become Due for Payment and which is made to a
Holder by or on behalf of the Trustee which has been deemed a preferential
transfer and theretofore recovered from its Holder pursuant to the United
States Bankruptcy Code in accordance with a final, nonappealable order of a
court of competent jurisdiction.

         "Required Payments" shall mean, as of any Payment Date, the sum of (i)
the Class A-8 Current Interest and the Class A-9 Current Interest plus any
Class A-8 and Class A-9 Interest Carry-Forward Amount and (ii) any Applied
Realized Loss Amount with respect to Group II.

                    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 LLP, 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 Group I
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
Group II 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 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 115% of the
"Prepayment Assumption" for Group I and 25% CPR for Group II.  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.

SUPPLEMENTAL INTEREST AMOUNTS

         The Beneficial Owners of the Group II Certificates and the related
rights to receive Supplemental Interest Amounts will be treated for tax
purposes as owning two separate investments:  (i)  the respective Group II
Certificates without the right to receive Supplemental Interest Amounts and
(ii) the right to receive the Supplemental Interest Amounts.  The Owners of the
respective Group II 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 Group II 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 Group II 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.

         If the Master Servicer, acting directly or through a permitted
designee, exercises its right to an Optional Termination, the Supplemental
Interest Amount may not be paid in full.

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.





                                     S-96
<PAGE>   97
         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;

         (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 Master
                 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 (the "Rating Agencies") 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.





                                     S-97
<PAGE>   98
         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").

         On July 21, 1997, the DOL published in the Federal Register amendments
to the Exemptions ("PTE 97-34"), which extend exemptive relief to certain
mortgage-backed and asset-backed securities transactions using pre-funding
accounts for trusts issuing pass-through certificates.  With respect to the
Certificates, PTE 97-34 generally allows Mortgage Loans supporting payments to
Owners of Certificates, and having a value equal to no more than 25% of the
total principal amount of the Certificates being offered by the Trust, to be
transferred to the Trust within a funding period no longer than 90 days or
three months following the Closing Date instead of requiring that all such
Mortgage Loans be either identified or transferred on or before the Closing
Date.  The relief will apply to the purchase, sale and holding of the
Certificates, provided that the following general conditions are met:

         (1)     the ratio of the amount allocated to the Pre-Funding Account
to the total principal amount of the Certificates being offered ("Pre-Funding
Limit") does not exceed 25%;

         (2)     all Subsequent Mortgage Loans meet the same terms and
conditions for eligibility as the original Mortgage Loans used to create the
Trust, which terms and conditions have been approved by the Rating Agencies;

         (3)     the transfer of such Subsequent Mortgage Loans to the Trust
during the Funding Period does not result in the Certificates to be covered by
the Exemptions receiving a lower credit rating from a Rating Agency upon
termination of the Funding Period than the rating that was obtained at the time
of the initial issuance of the Certificates by the Trust;

         (4)     solely as a result of the use of pre-funding, the weighted
average annual percentage interest rate (the "Average Interest Rate") for all
of the Mortgage Loans and Subsequent Mortgage Loans in the Trust at the end of
the Funding Period is not more than 100 basis points lower than the Average
Interest Rate for the Mortgage Loans which were transferred to the Trust on the
Closing Date;

         (5)     either:

         (i)         the characteristics of the Subsequent Mortgage Loans are
                     monitored by an insurer or other credit support provider
                     which is independent of the Sponsor; or

         (ii)        an independent accountant retained by the Depositor
                     provides the Sponsor with a letter (with copies provided
                     to the Rating Agencies, the Underwriter and the Trustee)
                     stating whether or not the characteristics of the
                     Subsequent Mortgage Loans conform to the characteristics
                     described in the Prospectus Supplement and/or Pooling and
                     Servicing Agreement.  In preparing such letter, the
                     independent accountant must use the same type of
                     procedures as were applicable to the Mortgage Loans which
                     were transferred to the Trust as of the Closing Date;

         (6)     the Funding Period ends no later than three months or 90 days
after the Closing Date or earlier in certain circumstances if the Pre-Funding
Account falls below the minimum level specified in the Pooling and Servicing
Agreement or an event of default occurs;

         (7)     amounts transferred to any Pre-Funding Account and/or
Capitalized Interest Account used in connection with the pre-funding may be
invested only in investments which are permitted by the Rating Agencies and:

         (i)         are direct obligations of, or obligations fully guaranteed
                     as to timely payment of principal and interest by, the
                     United States or any agency or instrumentality thereof
                     (provided that such obligations are backed by the full
                     faith and credit of the United States); or





                                     S-98
<PAGE>   99
         (ii)        have been rated (or the obligor has been rated) in one of
                     the three highest generic rating categories by such Rating
                     Agency;

         (8)     the Prospectus or Prospectus Supplement describes;

         (i)         any Pre-Funding Account and/or Capitalized Interest
                     Account;

         (ii)        the duration of the Funding Period;

         (iii)       the percentage and/or dollar amount of the Pre-Funding
                     Limit for the Funding Period that will be remitted to
                     Owners of Certificates as repayments of principal; and

         (iv)        that the amounts remaining in the Pre-Funding Account at
                     the end of the Funding Period will be remitted to Owners
                     of Certificates as repayments of principal; and

         (9)     the Pooling and Servicing Agreement describes the permitted
investments for the Pre-Funding Account and/or Capitalized Interest Account
and, if not disclosed in the Prospectus or Prospectus Supplement, the terms and
conditions for eligibility of Subsequent Mortgage Loans.

         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, as amended by PTE
97-34 (and, in the case of the Group II 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 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, as amended by PTE 97-34, 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 an Group II Certificate and the related right to
receive Supplemental Interest Amounts will have acquired, for purposes of ERISA
and for federal income tax purposes, such an Group II 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).

<PAGE>   100
SUBORDINATE CERTIFICATES

         The Exemptions, as amended by PTE 97-34, do not apply to the initial
purchase, the holding or the subsequent resale of the Mezzanine Certificates
and Class B-1 Certificates because such Certificates are subordinate to certain
other Classes of the Certificates. Accordingly, Plans may not purchase the
Subordinate Certificates, except that any insurance company may purchase such

                                    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 Standard & Poor's Ratings Group ("Standard &
Poor's") as set forth below:

         Explanations of the significance of such ratings may be obtained from
Moody's, 99 Church Street, New York, New York 10007 and Standard & Poor's, 25
Broadway, New York, New York 10006. 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 "r" of the "AAAr" rating of the Class A-IO Certificates by
Standard & Poor's is attached to highlight derivative, hydrid, and certain
other obligations that Standard & Poor's believes may experience high
volatility or high variability in expected returns due to non-credit risks.
Examples of such obligations are: securities whose principal or interest return
is indexed to equities, commodities, or currencies; certain swap and options;
and interest only and principal only mortgage securities.  The absence of an
"r" symbol should not be taken as an indication that an obligation will exhibit
no volatility or variability in total return.

         The Class A-8 and Class A-9 Insurer does not guarantee the payment of,
nor do the ratings assigned to the Group II Certificates address the likelihood
of the payment of any Supplemental Interest Amounts.

         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





                                     S-100
<PAGE>   101
do not represent any assessment of the likelihood that principal prepayments
may differ from those originally anticipated.

         Such ratings 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 Standard & Poor's
and the Sponsor has not provided information relating to the Offered
Certificates or the Mortgage Loans to any rating agency other than Moody's and
Standard & Poor's.  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 Moody's
and Standard & Poor's.



                        LEGAL INVESTMENT CONSIDERATIONS

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

         The Underwriters have agreed to reimburse the Sponsor for certain
expenses in connection with 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 1933
Act.

         Advanta Mortgage Conduit Services, Inc. has agreed to indemnify the
Underwriters against certain liabilities including liabilities under the 1933
Act.

         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 Lehman Brothers
Inc., 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.

         The Sponsor 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 any trading
markets for the Offered Certificates.
