                              "Certificate Rate"), payable monthly, and payments
                              of principal at such time and to the extent
                              provided below. The aggregate undivided interest
                              in the Trust represented by the Certificates as of
                              the Closing Date will equal $____________ (the
                              "Original Invested Amount"), which represents ___%
                              of the Cut-Off Date Pool Balance. The "Original
                              Certificate Principal Balance" will equal
                              $____________. Following the Closing Date, the
                              "Invested Amount" with respect to any date will be
                              an amount equal to the Original Invested Amount
                              minus (i) the amount of Investor Principal
                              Collections (as defined herein) previously
                              distributed to Certificateholders, and minus (ii)
                              an amount equal to the product of the Investor
                              Floating Allocation Percentage and the Liquidation
                              Loss Amounts (each as defined herein). The
                              Transferor (as described below) will own the
                              remaining undivided interest (the "Transferor
                              Interest") in the Mortgage Loans, which is equal
                              to the Pool Balance minus the Invested Amount and
                              will initially equal approximately __% of the
                              Cut-Off Date Pool Balance. The Transferor (the
                              "Transferor") as of any date is the owner of the
                              Transferor Interest, which initially will be Bank
                              One.

                              The Certificates will be issued pursuant to the
                              Agreement. The principal amount of the outstanding
                              Certificates (the "Certificate Principal Balance")
                              on any date is equal to the Original Certificate
                              Principal Balance minus the aggregate of amounts
                              actually distributed as principal to the
                              Certificateholders. See "DESCRIPTION OF THE

Removal of Certain 
Mortgage Loans; 
Additional Balances......     Subject to certain conditions, on any Distribution
                              Date the Transferor may, but shall not be
                              obligated to, remove from the Trust certain
                              Mortgage Loans without notice to the
                              Certificateholders. The Transferor is permitted to
                              randomly designate the Mortgage Loans to be
                              removed. Mortgage Loans so designated will only be
                              removed upon satisfaction of certain conditions
                              specified in the Agreement, including: (i) the
                              Transferor Interest as of the Transfer Date (as
                              defined herein) (after giving effect to such
                              removal) exceeds the Minimum Transferor Interest
                              (as defined below); (ii) the Transferor shall have
                              delivered to the Trustee a "Mortgage Loan
                              Schedule" containing a list of all Mortgage Loans
                              remaining in the Trust after such removal; (iii)
                              the Transferor shall represent and warrant that no
                              selection procedures which are adverse to the
                              interests of the Certificateholders or the
                              Certificate Insurer were used by the Transferor in
                              selecting such Mortgage Loans; (iv) in connection
                              with any such retransfer of Mortgage Loans, the
                              Rating Agencies (as defined herein) shall have
                              been notified of the proposed transfer and prior
                              to the Transfer Date the Rating Agencies shall
                              have notified the Transferor in writing that such
                              transfer will not result in a reduction or
                              withdrawal of the ratings assigned to the
                              Certificates without regard to the Policy; and (v)
                              the Transferor shall have delivered to the Trustee
                              and the Certificate Insurer an officer's
                              certificate confirming the conditions set forth in
                              clauses (i) through (iii) above. See "DESCRIPTION
                              OF THE CERTIFICATES-Optional Transfers of Mortgage
                              Loans to the Transferor."

                              The "Minimum Transferor Interest" as of any date
                              is an amount equal to the lesser of (a) __% of the
                              Pool Balance on such date and (b) the Transferor
                              Interest as of the Closing Date. During the term
                              of the Trust, all Additional Balances will be
                              transferred to and become property of the Trust.
                              The Pool Balance at any time will generally
                              fluctuate from day to day because the amount of
                              Additional Balances and the amount of principal
                              payments with respect to the Mortgage Loans will
                              usually differ from day to day. Because the
                              Transferor Interest is equal to the Pool Balance
                              minus the Invested Amount, the amount of the
                              Transferor Interest will fluctuate from day to day
                              as draws are made with respect to the Mortgage

                              Loans and as Principal Collections are received.

The Mortgage Loans.........   On the Closing Date, Bank One will sell the
                              Mortgage Loans to the Depositor, pursuant to a
                              purchase agreement (the "Purchase Agreement"). The
                              Cut-Off Date Principal Balance of the Mortgage
                              Loans was $____________. Weighted averages
                              described below are weighted on the basis of the
                              Cut-Off Date Principal Balance of all of the
                              Mortgage Loans. The Mortgage Loans are secured by
                              first, second or third mortgages on Mortgaged
                              Properties located in ___ states and the District
                              of Columbia. Approximately _____%, _____% and
                              _____% of the Mortgage Loans are secured by
                              Mortgaged Properties located in the states of
                              _______, ________ and ________, respectively. The
                              weighted average Combined Loan-to-Value Ratio of
                              the Mortgage Loans was _____% as of the Cut-Off
                              Date. The "Combined Loan-to-Value Ratio" or "CLTV"
                              of each Mortgage Loan is the ratio, expressed as a
                              percentage, of (a) the sum of (i) the greater of
                              the Cut-Off Date Principal Balance or the Credit
                              Limit and (ii) the principal balance of any senior
                              mortgage loan as of the origination of such
                              Mortgage Loan, over (b) the value (based on an
                              appraisal or other acceptable valuation method)
                              for the related Mortgaged Property determined at
                              the origination of such Mortgage Loan.

                              Interest accrues on each Mortgage Loan, payable
                              monthly, on the daily outstanding Principal
                              Balance thereof for each billing cycle at a
                              variable rate per annum (the "Loan Rate") equal at
                              any time to the sum of the applicable index, as
                              described herein under "DESCRIPTION OF THE
                              MORTGAGE LOANS Mortgage Loan Terms," as of the
                              first day of each related billing cycle (each such
                              date, an "Adjustment Date") plus a fixed
                              percentage amount (the "Gross Margin") specified
                              in the related Mortgage Note, computed on the
                              basis of a 365 day year times actual days elapsed.
                              The Gross Margins for the Mortgage Loans as of the
                              Cut-off Date ranged from __% to ____%. The
                              weighted average Gross Margins as of the Cut-Off
                              Date for Mortgage Loans indexed to a "prime rate"
                              and a "26 week T-Bill rate" were ____% and ____%
                              respectively. All of the Mortgage Loans are
                              subject to a maximum Loan Rate specified in the
                              related Credit Line Agreements (each, a "Maximum
                              Rate"). As of the Cut-off Date, the Maximum Rates
                              ranged from _____% per annum to _____% per annum

                              Loans have a minimum Loan Rate of _____% per
                              annum. The remaining Mortgage Loans do not have a
                              minimum Loan Rate. As of the Cut-Off Date, the
                              Loan Rates on the Mortgage Loans ranged from
                              _____% per annum to _____% per annum and the

                              as of the Cut-Off Date was $_____, the maximum
                              Principal Balance of any Mortgage Loan as of the
                              Cut-Off Date was $_________, and the average
                              Principal Balance of any Mortgage Loan as of the
                              Cut-Off Date was $_________. Approximately _____%
                              of the Mortgage Loans were secured by first
                              mortgages on the related Mortgaged Property,
                              _____% were secured by second mortgages and _____%
                              were secured by third mortgages. As of the Cut-Off
                              Date, the Mortgage Loans had remaining terms to
                              maturity ranging from ____ month to _____ months

                              Interest") will be equal to the percentage derived
                              by dividing the denomination of such Certificate
                              by the Original Certificate Principal Balance.

                              As to any Distribution Date, "Principal
                              Collections" will be equal to the sum of (i) the
                              amounts collected during the related Collection

                              Transfer Deposit Amounts (as defined herein).

                              "Net Liquidation Proceeds" with respect to a
                              Mortgage Loan are the proceeds (excluding amounts
                              drawn on the Policy) received in connection with
                              the liquidation of any Mortgage Loan, whether
                              through trustee's sale, foreclosure sale or
                              otherwise, reduced by related expenses, but not
                              including the portion, if any, of such amount that
                              exceeds the Principal Balance of the Mortgage Loan
                              plus any accrued and unpaid interest thereon to
                              the end of the Collection Period during which such

                              With respect to any Distribution Date, the portion

                              Certificates ("Investor Interest Collections")

                              any Distribution Date, the "Investor Floating
                              Allocation Percentage" is the percentage
                              equivalent of a fraction determined by dividing
                              the Invested Amount at the close of business on
                              the preceding Distribution Date (or at the Closing
                              Date in the case of the first Distribution Date)
                              by the Pool Balance at the beginning of the
                              related Collection Period. The remaining amount of
                              Interest Collections will be allocated to the
                              Transferor Interest as more fully described
                              herein.

                              On each Distribution Date, the Investor Interest
                              Collections will be applied in the following order
                              of priority: (i) as payment to the Trustee for its
                              fee for services rendered pursuant to the
                              Agreement; (ii) as payment for the premium for the
                              Policy; (iii) as payment for the accrued interest
                              due and any overdue accrued interest (with
                              interest thereon) on the Certificate Principal
                              Balance of the Certificates; (iv) as payment for
                              any Investor Loss Amount (as defined herein) for

                              the Certificates until the Invested Amount exceeds
                              the Certificate Principal Balance by the Required
                              Overcollateralization Amount, each as defined
                              herein (such amount, if any, paid pursuant to this
                              clause (vii) being referred to herein as the
                              "Accelerated Principal Distribution Amount");
                              (viii) any other amounts required to be deposited

                              Agreement or amounts owed to the Certificate
                              Insurer pursuant to the Insurance Agreement; (ix)
                              certain amounts that may be required to be paid to
                              the Servicer pursuant to the Agreement; and (x) to
                              the Transferor to the extent permitted as
                              described herein.

                              Investor Interest Collections available after the
                              payment of interest on the Certificates may be
                              insufficient to cover any Investor Loss Amount. If
                              such insufficiency results in the Certificate
                              Principal Balance exceeding the Invested Amount, a
                              draw in an amount equal to such difference will be
                              made on the Policy in accordance with the terms of
                              the Policy.

                              The "Overcollateralization Amount" on any date of
                              determination is the amount, if any, by which the
                              Invested Amount exceeds the Certificate Principal
                              Balance on such day. Payments to
                              Certificateholders pursuant to clause (iii) above
                              will be interest payments on the Certificates.
                              Payments to Certificateholders pursuant to clauses
                              (iv), (v) and (vii) will be principal payments on
                              the Certificates and will therefore reduce the
                              Certificate Principal Balance, however, payments
                              pursuant to clause (vii) will not reduce the
                              Invested Amount. The Accelerated Principal
                              Distribution Amount is not guaranteed by the
                              Policy.

                              "Liquidation Loss Amount" means with respect to
                              any Liquidated Mortgage Loan, the unrecovered
                              Principal Balance thereof at the end of the
                              related Collection Period in which such Mortgage
                              Loan became a Liquidated Mortgage Loan, after
                              giving effect to the Net Liquidation Proceeds

                              Principal Collections will be allocated between
                              the Certificateholders and the Transferor
                              ("Investor Principal Collections" and "Transferor

                              Mortgage Loans of ____% and ____%, respectively,
                              as of the Cut-Off Date (the "Fixed Allocation
                              Percentage"), but a lesser amount of Principal
                              Collections may be distributed to
                              Certificateholders during the Managed Amortization
                              Period, as described below. The "Investor Fixed
                              Allocation Percentage" shall be ____%.

                              Principal Collections in respect of the Mortgage
                              Loans in an account established for such purpose
                              under the Agreement (the "Collection Account").
                              See "DESCRIPTION OF THE CERTIFICATES-Payments on
                              Mortgage Loans; Deposits to Collection Account."

Collection Period..........   As to any Distribution Date other than the first
                              Distribution Date, the "Collection Period" is the
                              calendar month preceding the month of such
                              Distribution Date. As to the first Distribution
                              Date, the "Collection Period" is the period
                              beginning on the day immediately following the
                              Cut-Off Date and ending on __________, 199_.

Interest...................   Interest on the Certificates will be distributed
                              monthly on the [fifteenth] day of each month or,
                              if such day is not a Business Day, then the next
                              succeeding Business Day (each, a "Distribution
                              Date"), commencing on ______ 15, 199_, at the

                              (as defined below). The "Certificate Rate" for an
                              Interest Period will generally equal the sum of
                              (a) the London Interbank Offered Rate for
                              one-month Eurodollar deposits ("LIBOR") appearing
                              on the Telerate Screen Page 3750, as of the second

                              two LIBOR Business Days prior to the Closing Date,
                              in the case of the first Interest Period) and (b)
                              %. Notwithstanding the foregoing, in no event will
                              the amount of interest required to be distributed

                              payable to the Trustee and the rate at which the

                              Period will equal, to the extent funds are

                              the Investor Fixed Allocation Percentage may
                              result in distributions of principal to
                              Certificateholders in amounts that are greater
                              relative to the declining Pool Balance than would
                              be the case if the Investor Floating Allocation
                              Percentage were used to determine the percentage
                              of Principal Collections distributed in respect of
                              the Invested Amount. The aggregate distributions
                              of principal to Certificateholders will not exceed
                              the Original Certificate Principal Balance.

                              Balance and accrued and unpaid interest thereon at
                              the Certificate Rate through the day preceding the
                              final Distribution Date. See "DESCRIPTION OF THE

Trustee....................   _________________, a ______________ (the
                              "Trustee"), will act as Trustee on behalf of the
                              Certificateholders.

Mandatory Retransfer of
Certain Mortgage Loans.....   The Seller will make certain representations and
                              warranties in the Agreement with respect to the
                              Mortgage Loans. If the Seller breaches certain of
                              its representations and warranties with respect to
                              any Mortgage Loan and such breach materially and
                              adversely affects the interests of the
                              Certificateholders or the Certificate Insurer and
                              is not cured within the specified period, the
                              Mortgage Loan will be removed from the Trust upon
                              the expiration of a specified period from the date
                              on which the Seller becomes aware or receives
                              notice of such breach and will

Federal Tax
Considerations.............   [Subject to the qualifications set forth in
                              "CERTAIN FEDERAL INCOME TAX CONSEQUENCES" herein,
                              special tax counsel to the Depositor is of the
                              opinion that, under existing law, (i) a
                              Certificate will be treated as a debt instrument
                              for Federal income tax purposes as of the Closing
                              Date and (ii) the Trust will not be characterized
                              as an association (or publicly traded partnership)
                              taxable as a corporation or as a taxable mortgage
                              pool within the meaning of Section 7701 (i) of the
                              Code. Under the Agreement, the Transferor, the
                              Depositor and the Certificateholders will agree to
                              treat the Certificates as indebtedness for Federal
                              income tax purposes. See "CERTAIN FEDERAL INCOME
                              TAX CONSIDERATIONS" [herein and] in the Prospectus
                              for additional information concerning the
                              application of Federal income tax laws.]

ERISA Considerations.......   [The Certificates may be purchased by or on behalf
                              of an employee benefit plan or other retirement
                              arrangement that is subject to the Employee
                              Retirement Income Security Act of 1974, as amended
                              ("ERISA"), or Section 4975 of the Internal Revenue
                              Code of 1986, as amended (the "Code"), as well as
                              any entity whose source of funds for the purchase
                              of the Certificates includes plan assets by reason
                              of a plan or account investing in such entity
                              (each, a "Plan"), subject to the considerations
                              described herein. Any Plan fiduciary considering
                              whether to purchase any Certificate on behalf of a
                              Plan should consult with its counsel regarding the
                              applicability of the provisions of ERISA and the
                              Code. See "ERISA CONSIDERATIONS" [herein and] in
                              the Prospectus.]

Legal Investment
Considerations.............   The Certificates will not constitute "mortgage
                              related securities" for purposes of the Secondary
                              Mortgage Market Enhancement Act of 1984 ("SMMEA"),
                              because not all of the Mortgages securing the
                              Mortgage Loans are first mortgages. Accordingly,
                              many institutions with legal authority to invest
                              in comparably rated securities based solely on
                              first mortgages may not be legally authorized to
                              invest in the Certificates. See "LEGAL INVESTMENT
                              CONSIDERATIONS" herein and "LEGAL

                              INVESTMENT" in the Prospectus.

Certificate Rating.........   It is a condition to the issuance of the
                              Certificates that they be rated "___" by
                              _____________ and "___" by ______ (each, a "Rating
                              Agency"). In general, ratings address credit risk
                              and do not address the likelihood of prepayments.
                              See "RATINGS" herein and "RISK FACTORS-Rating of
                              the Securities" in the Prospectus.

- --------------------------------------------------------------------------------


                                      S-19
<PAGE>   21

                                  RISK FACTORS

      Book-Entry Certificates. Issuance of the Certificates in book-entry form
may reduce the liquidity of such Certificates in the secondary trading market
since investors may be unwilling to purchase Certificates for which they cannot
obtain physical certificates. See "DESCRIPTION OF THE CERTIFICATES-Book-Entry
Certificates" herein.

      Since transactions in the Certificates can be effected only through DTC,
Cedel, Euroclear, participating organizations, indirect participants and certain
banks, the ability of a Certificate Owner to pledge a Certificate to persons or
entities that do not participate in the DTC, Cedel or Euroclear system or
otherwise to take actions in respect of such Certificates, may be limited due to
lack of a physical certificate representing the Certificates. See "DESCRIPTION
OF THE CERTIFICATES-Book-Entry Certificates" herein.

      Certificate Owners may experience some delay in their receipt of
distributions of interest and principal on the Certificates since such
distributions will be forwarded by the Trustee to DTC and DTC will credit such
distributions to the accounts of its Participants (as defined herein) which will
thereafter credit them to the accounts of Certificate Owners either directly or
indirectly through indirect participants. See "DESCRIPTION OF THE
CERTIFICATES-Book-Entry Certificates" herein.

      Cash Flow Considerations. Minimum monthly payments on the Mortgage Loans
may be limited to accrued interest. Although borrowers under certain of the
Mortgage Loans may choose to pay down all or a part of their outstanding
principal balance prior to maturity, such borrowers are under no obligation to
do so and, in the event such balances have not been substantially paid down
prior to maturity, some borrowers may be unable to pay the required final
payment.

      Even assuming that the Mortgaged Properties provide adequate security for
the Mortgage Loans, substantial delays could be encountered in connection with
the liquidation of Mortgage Loans that are delinquent and resulting shortfalls
in distributions to Certificateholders could occur [if the Certificate Insurer
were unable to perform on its obligations under the Policy.] Further,
liquidation expenses (such as legal fees, real estate taxes, and maintenance and
preservation expenses) will reduce the proceeds payable to Certificateholders
and thereby reduce the security for the Mortgage Loans. In the event any of the
Mortgaged Properties fail to provide adequate security for the related Mortgage
Loans, Certificateholders could experience a loss [if the Certificate Insurer
were unable to perform its obligations under the Policy].

      Prepayment Considerations. Substantially all of the Mortgage Loans may be
prepaid in whole or in part at any time without penalty. Home equity loans, such
as the Mortgage Loans, have been originated in significant volume only during
the past few years and neither the Depositor nor the Servicer is aware of any
publicly available studies or statistics on the rate of prepayment of such
loans. Generally, home equity loans are not viewed by borrowers as permanent
financing. Accordingly, the Mortgage Loans may experience a higher rate of
prepayment than traditional mortgage loans. The Trust's prepayment experience
may be affected by a wide variety of factors, including general economic
conditions, interest rates, the availability of alternative financing and
homeowner mobility. In addition, substantially all of the


                                      S-20
<PAGE>   22

Mortgage Loans contain due-on-sale provisions and the Servicer intends to
enforce such provisions unless (i) such enforcement is not permitted by
applicable law or (ii) the Servicer, in a manner consistent with reasonable
commercial practice, permits the purchaser of the related Mortgaged Property to
assume the Mortgage Loan. To the extent permitted by applicable law, such
assumption will not release the original borrower from its obligation under any
such Mortgage Loan. See "DESCRIPTION OF THE CERTIFICATES" herein and "CERTAIN
LEGAL ASPECTS OF LOANS-`Due-on-Sale' Clauses" in the Prospectus for a
description of certain provisions of the Credit Line Agreements that may affect
the prepayment experience on the Mortgage Loans.

      Certificate Rating. The rating of the Certificates will depend primarily
on an assessment by the Rating Agencies of the Mortgage Loans and [upon the
claims-paying ability of the Certificate Insurer]. [Any reduction in a rating
assigned to the claims-paying ability of the Certificate Insurer below the
rating initially given to the Certificates may result in a reduction in the
rating of the Certificates.] The rating by the Rating Agencies of the
Certificates is not a recommendation to purchase, hold or sell the Certificates,
inasmuch as such rating does not comment as to the market price or suitability
for a particular investor. There is no assurance that the ratings will remain in
place for any given period of time or that the ratings will not be lowered or
withdrawn by the Rating Agencies. In general, the ratings address credit risk
and do not address the likelihood of prepayments. The ratings of the
Certificates do not address the possibility of the imposition of United States
withholding tax with respect to non-U.S. persons.

      Legal Considerations. The Mortgage Loans are secured by mortgages (which
are first, second or third mortgages) on the Mortgaged Properties. With respect
to Mortgage Loans that are secured by first mortgages, the Servicer has the
power under certain circumstances to consent to a new mortgage lien on the
Mortgaged Property having priority over such Mortgage Loan. Mortgage Loans
secured by junior mortgages are entitled to proceeds that remain from the
liquidation or similar sale of the related Mortgaged Property after payment of
liquidation expenses (such as legal fees, real estate taxes, and maintenance and
preservation expenses) and payments of any related senior mortgage lien and
prior statutory liens. In the event that such proceeds are insufficient to
satisfy such liquidation expenses, senior loans and prior liens in the aggregate
and the Certificate Insurer is unable to perform its obligations under the
Policy, the Certificateholders will bear (i) the risk of delay in distributions
while a deficiency judgment against the borrower is obtained and (ii) the risk
of loss if the deficiency judgment cannot be obtained or cannot be realized
upon. In addition, a junior mortgagee may not foreclose on the property securing
a junior mortgage unless it forecloses subject to all senior liens. See "CERTAIN
LEGAL ASPECTS OF LOANS" in the Prospectus.

      Under the terms of the Agreement, so long as Bank One's long-term senior
unsecured debt is rated at least "___" by ________ and "___" by ________, the
Servicer will be entitled to maintain possession of the documentation relating
to each Mortgage Loan sold by it, including the Credit Line Agreements and the
Related Documents or other evidence of indebtedness signed by the borrower, and
the assignments of the related mortgages to the Trust will not be required to be
recorded. Failure to deliver the Related Documents to the Trustee will have the
result in most, if not all, of the states in which the Related Documents will be
held, and failure to record the assignments of the related mortgages to the
Trustee will have the result in certain states in which the Mortgaged Properties
are located, of making the sale of the Cut-Off Date Principal


                                      S-21
<PAGE>   23

Balances, Additional Balances and Related Documents potentially ineffective
against (i) any creditors of Bank One, who may have been fraudulently or
inadvertently induced to rely on the Mortgage Loans as assets of Bank One or
(ii) any purchaser of a Mortgage Loan who had no notice of the prior conveyance
to the Trust Fund if such purchaser perfects his interest in the Mortgage Loan
by taking possession of the Related Documents or other evidence of indebtedness
or otherwise.

      Bank One warrants in the Purchase Agreement that the transfer by it of all
of its right, title and interest in and to the Mortgage Loans subject to the
Agreement is either a valid transfer and assignment of the Mortgage Loans or the
grant to the Trust of a security interest in the Mortgage Loans. If the transfer
of Mortgage Loans to the Trust is deemed to create a security interest therein
under the Uniform Commercial Code (the "UCC") of an applicable state, any tax or
governmental lien on property of Bank One arising before any Mortgage Loan comes
into existence might have priority over the Trust's interest in such Mortgage
Loan. In addition, if the FDIC were appointed receiver of Bank One, the
receiver's administrative expenses might also have priority over the Trust's
interest in such Mortgage Loan. If an Insolvency Event were to occur with
respect to Bank One, then a Rapid Amortization Event would occur and, pursuant
to the terms of the Agreement, new Additional Balances would not be transferred
to the Trust by Bank One. In addition, if Bank One were to be dissolved as a
result of an Insolvency Event (other than pursuant to a merger, consolidation or
sale of substantially all of its assets), the Trustee, unless otherwise
instructed by more than 50% of the Certificateholders, would sell the Mortgage
Loans in a commercially reasonable manner as described below under "Description
of the Certificates-Rapid Amortization Events," thereby causing early
termination of the Trust and a loss to Certificateholders if the net proceeds of
such sale allocable to the Certificateholders were insufficient to pay such
Certificateholders in full. The proceeds from the sale, disposition or
liquidation of the Mortgage Loans will first be paid to the Certificate Insurer
to the extent of unreimbursed draws under the Policy and other amounts owing to
the Certificate Insurer pursuant to the Insurance Agreement.

      The Federal Deposit Insurance Act (as amended, "FDIA") sets forth certain
powers that the FDIC could exercise if it were appointed conservator or receiver
of Bank One. To the extent (i) Bank One grants a security interest in the
Mortgage Loans to the Trust, (ii) such security interest is validly perfected
before the occurrence of an Insolvency Event and (iii) such security interest
was not taken in contemplation of insolvency or with the intent to hinder, delay
or defraud Bank One or its creditors, such security interest should not be
subject to avoidance by the FDIC if the FDIC is appointed as a conservator or
receiver of Bank One. Subject to clarification by regulations or
interpretations, positions taken by the staff of the FDIC prior to the passage
of the Financial Institutions Reform, Recovery, and Enforcement Act of 1989 (as
amended "FIRREA") do not suggest that the FDIC, as receiver or conservator for
Bank One, would interfere with the timely transfer to the Trust of payments
collected on the Mortgage Loans. If, however, the FDIC were to assert a contrary
position, certain provisions of the FDIA which, at the request of the FDIC, have
been applied in recent lawsuits to avoid security interest in collateral granted
by depository institutions, may permit the FDIC to avoid such security interest,
thereby resulting in possible delays and reduction in payments to the
Certificateholders. Further, if the FDIC were to require the Trustee to comply
with certain administrative claims procedures under the FDIA before the Trust
could collect, sell, dispose of or otherwise liquidate the Mortgage Loans or if
the conservator or receiver were to obtain a stay of proceedings with


                                      S-22
<PAGE>   24

respect to Bank One as provided in the FDIA, delays in payment and possible
reductions in the amount of those payments could occur. Upon the occurrence of
an Insolvency Event, if no Rapid Amortization Event other than such Insolvency
Event exists, the FDIC may have the power to continue to require the Seller to
transfer new Additional Balances to the Trust and to prevent the early sale,
liquidation or disposition of the Mortgage Loans and the commencement of the
Rapid Amortization Period. In addition, such receiver may have the power to
cause the early sale of the Mortgage Loans and the early retirement of the
Certificates notwithstanding instructions from the Certificateholders
instructing the Trust not to sell the Mortgage Loans. In the event of an Event
of Servicing Termination if a conservator, receiver or liquidator is appointed
for the Servicer and no Event of Servicing Termination other than such
conservatorship, receivership, liquidation or insolvency of the Servicer exists,
the conservator, receiver or liquidator may have the power to prevent either the
Trust or the Certificateholders from appointing a successor Servicer.

      Geographic Concentration. As of the Cut-Off Date, approximately ____%,
____% and _____% (by Cut-Off Date Pool Balance) of the Mortgaged Properties are
located in the States of _________, __________ and _________, respectively. An
overall decline in the residential real estate markets in these states could
adversely affect the values of the Mortgaged Properties securing such Mortgage
Loans such that the Principal Balances of the related Mortgage Loans, together
with any primary financing on such Mortgaged Properties, could equal or exceed
the value of such Mortgaged Properties. As the residential real estate market is
influenced by many factors, including the general condition of the economy and
interest rates, no assurances may be given that the residential real estate
markets in these states will not weaken. If these residential real estate
markets should experience an overall decline in property values after the dates
of origination of the Mortgage Loans, the rates of losses on the Mortgage Loans
would be expected to increase, and could increase substantially.

      Servicer's Ability to Change the Terms of the Mortgage Loans. The Servicer
may agree to changes in the terms of a Credit Line Agreement, provided that such
changes (i) do not adversely affect the interest of the Certificateholders or
the Certificate Insurer, and (ii) are consistent with prudent business practice.
There can be no assurance that changes in applicable law or the marketplace for
home equity loans or prudent business practice will not result in changes in the
terms of the Mortgage Loans. In addition, the Agreement permits the Servicer,
within certain limitations described therein, to increase the Credit Limit of
the related Mortgage Loan or reduce the Margin for such Mortgage Loan.

      [Delinquent Mortgage Loans. The Trust will include Mortgage Loans which
are 89 or fewer days delinquent as of the Cut-Off Date. The Cut-Off Date
Principal Balance of Mortgage Loans which are between 30 days and 89 days
delinquent as of the Cut-Off Date was $_________. If there are not sufficient
funds from the Investor Interest Collections to cover the Investor Loss Amounts
for any Distribution Date, the Overcollateralization Amount and the amount on
deposit in the Spread Account have been reduced to zero, and the Certificate
Insurer fails to perform its obligations under the Policy, the aggregate amount
of principal returned to the Certificateholders may be less than the Certificate
Principal Balance on the day the Certificates are issued.]

                                  THE SERVICER

General

      The Servicer will service the Mortgage Loans in accordance with the terms
set forth in the Agreement. As of the Closing Date, the Servicer will service
the Mortgage Loans without subservicing arrangements. The Servicer may perform
any of its obligations under the Agreement through one or more subservicers and
is permitted under the Agreement to transfer servicing to affiliates, provided
such affiliate meets certain standards specified in the Agreement. See
"DESCRIPTION OF THE CERTIFICATES-Certain Matters Regarding the Servicer and the
Transferor." Notwithstanding any subservicing arrangements, the Servicer will
remain liable for its servicing duties and obligations under the Agreement as if
the Servicer alone were servicing the Mortgage Loans.

[Additional information to be added, if applicable]

The Servicer

      Bank One, N.A. ("Bank One" and, in its capacity as servicer, the
"Servicer") is a national banking association and an indirect, wholly-owned
subsidiary of BANC ONE CORPORATION, an Ohio corporation. As of __________, 199_,
Bank One had consolidated total assets of approximately $___ billion, total
deposits of approximately $___ billion and total equity capital of approximately
$___ million. The principal executive offices of Bank One are located at 100
East Broad Street, Columbus, Ohio.

Servicing of the Mortgage Loans

      The Servicer has established standard policies for the servicing and
collection of the home equity loans owned and serviced by it or serviced by it
for others. Servicing includes: (a) the collection and aggregation of payments
relating to the loans; (b) the supervision of delinquent loans, loss mitigation
efforts, foreclosure proceedings and, if applicable, the disposition of
mortgaged properties; and (c) the preparation of tax related information in
connection with the loans.

      Billing statements are mailed monthly by the Servicer. The statement
details all debits and credits and specifies the minimum payment due and the
available credit line. Notice of changes in the applicable loan rate are
provided by the Servicer to the borrower with such statements.

      Collections efforts are initiated once the loan becomes past due. Late fee
notices are sent to borrowers within 16 days after the Due Date and a collector
attempts to contact the borrower. It is the Servicer's policy to suspend drawing
privileges on overdue loans until the borrower brings the loan current. Once the
loan is 30 days delinquent, the Servicer reports the delinquency to credit
reporting bureaus. During the period when the loan is 45 to 59 days delinquent,
the


                                      S-26
<PAGE>   28

Servicer sends a notice of default to the borrower informing the borrower of its
intent to initiate foreclosure proceedings on the mortgaged property within 30
days. During this time, the Servicer contacts senior lienholders, if any, to
determine the status of such liens. After a loan is 60 days past due, the
Servicer orders a broker's price opinion and/or a drive-by appraisal and
property inspection may be conducted.

      When the notice of default to the borrower expires (during the period 75
to 89 days after the loan has become due), the Servicer determines whether to
initiate foreclosure proceedings on the mortgaged property after performing an
equity position analysis on the borrower's loan to determine if there is
sufficient equity in the underlying property to repay the senior mortgage, if
any, the borrower's home equity loan and estimated foreclosure expenses. The
general policy of the Servicer is to initiate foreclosure on the underlying
property after the loan is ninety days or more delinquent if the Servicer has
determined that no further action on its part will cause the default to be
cured.

      The Servicer may terminate foreclosure proceedings if the delinquency is
cured. Foreclosures initiated on a junior lien are subject to the payment of
foreclosure expenses, the senior mortgage or mortgages and any outstanding
property taxes and other statutory liens. Once foreclosure proceedings are
initiated by the Servicer the loan is transferred to the Foreclosure Department.
The Foreclosure Department uses a tracking system to monitor the progress of
such proceedings. The tracking system includes parameters for each state in
which mortgaged properties are located, which are used to monitor whether the
foreclosure is progressing within a typical time frame for the state in which
the mortgaged property is located.

      After foreclosure, if the loan is secured by a first mortgage lien, the
Servicer may liquidate the mortgaged property and charge-off the home equity
loan balance that was not recovered through proceeds of the liquidation, if any.
If the mortgaged property was subject to a senior lien, the Servicer will either
directly manage the foreclosure sale of the mortgaged property and satisfy such
lien at the time of sale or take other action as it deems necessary to protect
the interest in the mortgaged property. If, in the judgment of the Servicer, the
cost of maintaining or purchasing the senior lien exceeds the economic benefit
of such action, the Servicer will generally charge-off the entire unpaid
principal amount of the loan, seek a judgment against the borrower and not
pursue any recovery.

      At __________, 199_, the Servicer serviced a total portfolio of
approximately ________ home equity loans having aggregate unpaid principal
balances of approximately $____ billion. The foregoing figures include home
equity loans that were originated or acquired by Bank One or its affiliates and
are serviced on a contractual basis.

Delinquency and Loss Experience.

      The following table summarizes the delinquency and loss experience of home
equity loans owned by Bank One and its affiliates and serviced by the Servicer.
The statistical information in such tables does not include home equity loans
serviced by the Servicer for entities other than Bank One and its affiliates.
The information in the tables below has not been adjusted to eliminate the
effect of the unseasoned nature of the home equity loan portfolio during the
period shown. Accordingly, loss and delinquency as percentages of aggregate
principal


                                      S-27

balance of Mortgage Loans serviced for each period would be higher than those
shown if a group of Mortgage Loans were artificially isolated at a point in time
and the information showed the activity only in that isolated group. However,
since most of the mortgage loans in Bank One's and its affiliates' home equity
loan portfolio will not be fully seasoned and since the terms of most Mortgage
Loans will not call for payment of principal in full prior to maturity, the
delinquency and loss information for such an isolated group would also be
distorted to some degree. The tables below present real estate revolving credit
line loan data applicable to substantially all of the United States operations
of Bank One and its affiliates, including loans managed in states which are not
represented in the mortgage pool consisting of the Mortgage Loans currently
serviced by Bank One and real estate acquired through foreclosure.

                        DESCRIPTION OF THE MORTGAGE LOANS

General

      All of the Mortgage Loans will be purchased on the Closing Date by the
Depositor from the Seller, without recourse, pursuant to the Purchase Agreement.
[The Seller acquired the Mortgage Loans from affiliated banks of the Seller.]

      All weighted averages described below are weighted on the basis of Cut-Off
Date Principal Balance of the Mortgage Loans included in the Trust.

      The Mortgage Loans were originated between ____ and ____. The Cut-Off Date
Principal Balance of the Mortgage Loans was $___________, which is equal to the
aggregate Principal Balances of the Mortgage Loans as of the close of business
on _________, 199_ (the "Cut-Off Date"). _____% of the Mortgage Loans were
secured by a first Mortgage on the related Mortgaged Property, _____% of the
Mortgage Loans were secured by second Mortgages and _____% of the Mortgage Loans
were secured by third Mortgages. The minimum Principal Balance of the Mortgage
Loans as of the Cut-Off Date was $____, the maximum Principal Balance of the
Mortgage Loans as of the Cut-Off Date was $_________, and the average Principal
Balance of the Mortgage Loans as of the Cut-Off Date was $__________. As of the
Cut-Off Date, the Loan Rates on the Mortgage Loans ranged from _____% per annum
to _____% per annum and the weighted average Loan Rate was _____% per annum. The
weighted average (weighted by Credit Limit) Credit Limit Utilization Rate
(defined below) of the Mortgage Loans was _____% as of the Cut-Off Date. The
weighted average Combined Loan-to-Value Ratio (defined below) of the Mortgage
Loans was _____% as of the Cut-Off Date and the weighted average junior mortgage
ratio of the Mortgage Loans (computed by dividing the greater of the Credit
Limit and the Cut-Off Date Principal Balance for each Mortgage Loan, provided
such Mortgage Loan was in a junior lien position, by the sum of such Credit
Limit or Cut-Off Date Principal Balance as applicable and the outstanding
balances at the time such Mortgage Loan was originated of all senior mortgage
loans affecting the Mortgaged Property) was approximately _____%. No Mortgage
Loan had a Combined Loan-to-Value Ratio greater than ____%. The latest scheduled
maturity of any Mortgage Loan is in ______ 20__. As of the Cut-Off Date, _____%
of the Mortgage Loans were secured by Mortgaged Properties that are detached
single-family residences, _____% of the Mortgage Loans were secured by Mortgage
Properties that are two- to four-family residences, _____% of the Mortgage Loans
are secured by Mortgaged Properties that are condominium units, and _____% of
the Mortgage Loans are secured by Mortgaged Properties that are units in planned
unit developments. As of the Cut-Off Date, _____% of the Mortgage Loans were
secured by Mortgaged Properties that are owner-occupied, and _____% of the
Mortgage Loans were secured by non-owner occupied Mortgaged Properties.
Approximately _____%, _____% and _____% of the Mortgage Loans were secured by
Mortgaged Properties in ____________, ___________ and __________, respectively.
_____% of the Mortgage Loans were contractually delinquent 30 days or more. No
Mortgage Loan was delinquent more than 89 days.

      The "Combined Loan-to-Value Ratio" or "CLTV" of each Mortgage Loan is the
ratio, expressed as a percentage, of (a) the sum of (i) the greater of the
Cut-Off Date Principal Balance


                                      S-30
<PAGE>   32

or the Credit Limit and (ii) the principal balance of any senior mortgage loan
as of the origination of such Mortgage Loan, over (b) the value (based on an
appraised value or other acceptable valuation method) for the related Mortgaged
Property determined in the origination of such Mortgage Loan. The "Credit Limit
Utilization Rate" is determined by dividing the Cut-Off Date Principal Balance
of a Mortgage Loan by the Credit Limit of such Mortgage Loan.

Mortgage Loan Terms

      The Mortgage Loans were originated pursuant to loan agreements (the
"Credit Line Agreements"). Under the Credit Line Agreements, the borrowers may
receive advances (an "Additional Balance" or a "Draw") at any time either during
the term of such Mortgage Loan or during a specified period (the "Draw Period").
Bank One does not require Draws be in a minimum amount. The maximum amount of
each Draw with respect to any Mortgage Loan is equal to the excess, if any, of
the Credit Limit over the Principal Balance outstanding under such Mortgage Note
at the time of such Draw.

      The borrower's right to make a Draw under a Mortgage Loan may be
suspended, or the Credit Limit may be reduced under a number of circumstances,
including, but not limited to, a material adverse change in the borrower's
financial circumstances, a significant decline in the Appraised Value of the
Mortgaged Property or a non-payment default by the borrower. Generally, such
suspension or reduction will not affect the payment terms for previously drawn
balances. In the event of default under a Mortgage Loan, the right of the
borrower to make a Draw may be terminated and the entire outstanding Principal
Balance of such Mortgage Loan may be declared immediately due and payable. A
"default" includes, but is not limited to, the borrower's failure to make any
payment as required, any action or inaction by the borrower that adversely
affects the Mortgaged Property or the rights in the Mortgaged Property or any
fraud or material misrepresentation by a borrower in connection with the
Mortgage Loan. The Credit Limit may also be increased, upon completion of
satisfactory underwriting review, as described below.

      Interest (the "Finance Charge") accrues on each Mortgage Loan, payable
monthly, on the related average daily outstanding Principal Balance for each
Billing Cycle at a variable rate per annum (the "Loan Rate") equal at any time
to the sum of the applicable Index (defined below) as of the first day of each
related Billing Cycle (such date, the "Adjustment Date") as described below plus
a fixed percentage amount (the "Gross Margin") specified in the related Mortgage
Note, computed on the basis of a 365 day year times actual days elapsed. The
"Billing Cycle" for each Mortgage Loan is the calendar month preceding each Due
Date. The "Due Date" for payments under each Mortgage Loan is the twentieth day
of each month.

      The Finance Charge accrued each month with respect to each Mortgage Loan
adjusts based on an index (each, an "Index"). _____% of the Mortgage Loans bear
interest at rates which adjust in accordance with the "prime rate" as published
in the "Money Rates" table in The Wall Street Journal on the related Adjustment
Date; _____% of the Mortgage Loans bear interest at rates which adjust in
accordance with the rate announced by Citibank, N.A. as its "base rate" on the
related Adjustment Date; _____% of the Mortgage Loans bear interest at rates
which adjust based on the current coupon equivalent of the rate for 26-Week U.S.
Treasury Bills in the calendar month immediately preceding the month in which
the related Adjustment Date occurs,


                                      S-31
<PAGE>   33

as published in The Wall Street Journal, and _____% of the Mortgage Loans bear
interest at rates which adjust based on the current auction average of rates for
26-Week U.S. Treasury Bills as published in The Wall Street Journal. The Gross
Margins for the Mortgage Loans as of the Cut-Off Date ranged from _____% to
_____%. The weighted average Gross Margins as of the Cut-Off Date for Mortgage
Loans indexed to a "prime rate" and a "26 week T-Bill rate" were _____% and
_____% respectively. All of the Mortgage Loans are subject to a maximum Loan
Rate specified in the related Credit Line Agreements (each, a "Maximum Rate").
As of the Cut-Off Date, the Maximum Rates ranged from _____% per annum to _____%
per annum and the weighted average Maximum Rate was _____% per annum. As of the
Cut-Off Date, _____% of the Mortgage Loans have a minimum Loan Rate of _____%
per annum and _____% of the Mortgage Loans have a minimum Loan Rate of _____%
per annum. The remaining Mortgage Loans do not have a minimum Loan Rate. No
Mortgage Loan is subject to a periodic rate cap.

      The Mortgage Loans had original terms to maturity ranging from ____ years
to ____ years. As of the Cut-Off Date, the Mortgage Loans had remaining terms to
maturity ranging from ____ month to ____ months and a weighted average months
remaining to scheduled maturity of ____ months.

      Payments made by or on behalf of the borrower for each Mortgage Loan are
generally required to be applied, first, to any unpaid Finance Charges, second,
to any other unpaid Additional Charges and third, to the Principal Balance
outstanding with respect to such Mortgage Loan. With respect to certain of the
Mortgage.

      Loans, payments are required to be applied to unpaid insurance premiums
and late charges (in that order) prior to application to Finance Charges, as
described above.

      The Mortgage Loans have various loan terms, draw periods, amortization
periods and minimum monthly payment requirements as follows:

(1)   Loan designation three has a maximum draw period of 20 years; however,
      after each five year period, the borrower's credit quality and recent
      payment history are reviewed to determine if Bank One will either renew
      the loan at the same rate and terms for an additional five years, (ii)
      convert the existing balance to a fixed term loan with regular monthly
      principal and interest payments sufficient to amortize the loan over the
      remaining period of the 20 year term, or (iii) to renew the note at a new
      rate, new index, and/or with such new terms that will be determined solely
      at the discretion of Bank One.

(2)   Following the 9.5 year draw period and subsequent three month
      interest-only period, loans originated under designation five will
      amortize monthly at the then applicable loan rate and remaining term to
      produce a payment sufficient to amortize the loan to zero over its
      remaining term.

                                  UNDERWRITING

         [Insert to describe differences with respect to specific Pool]

                     MATURITY AND PREPAYMENT CONSIDERATIONS

      The Agreement, except as otherwise described herein, provides that the
Certificateholders will be entitled to receive on each Distribution Date
distributions of principal, in the amounts described herein, until the
Certificate Principal Balance is reduced to zero. During the Managed
Amortization Period, Certificateholders will receive amounts from Principal
Collections based upon their Fixed Allocation Percentage subject to reduction as
described below. During the Rapid Amortization Period, Certificateholders will
receive amounts from Principal Collections based solely upon their Fixed
Allocation Percentage. Because prior distributions of Investor Principal
Collections to Certificateholders reduce the Investor Floating Allocation
Percentage but do not change the Fixed Allocation Percentage, allocations of
Principal Collections based on the Fixed Allocation Percentage may result in
distributions of principal to the Certificateholders in amounts that are, in
most cases, greater relative to the declining balance of the Mortgage Loans than
would be the case if the Investor Floating Allocation Percentage were used to
determine the percentage of Principal Collections distributed to
Certificateholders. This is especially true during the Rapid Amortization Period
when the Certificateholders are entitled to receive Investor Principal
Collections and not a lesser amount. In addition, Investor Interest Collections
may be distributed as principal to Certificateholders in connection with the
Accelerated Principal Distribution Amount, if any. Moreover, to the extent of
losses allocable to the Certificateholders, Certificateholders may also receive
as payment of principal the Floating Allocation Percentage of the amount of such
losses either from Investor Interest Collections or, in some instances, draws
under the Policy. The level of losses may therefore affect the rate of payment
of principal on the Certificates.

      To the extent obligors make more Draws than principal payments, the
Transferor Interest may grow. Because during the Rapid Amortization Period the
Certificateholders share of Principal Collections is based upon its Fixed
Allocation Percentage (without reduction), an increase in the Transferor
Interest due to additional Draws may also result in Certificateholders receiving
principal at a greater rate than would otherwise occur if the Investor Floating
Allocation Percentage were used to determine the percentage of Principal
Collections distributed to Certificateholders. The Agreement permits the
Transferor, at its option, but subject to the satisfaction of certain conditions
specified in the Agreement, including the conditions described below, to remove
certain Mortgage Loans from the Trust at any time during the life of the Trust,
so long as the Transferor Interest (after giving effect to such removal) is not
less than the Minimum Transferor Interest. Such removals may affect the rate at
which principal is distributed to Certificateholders by reducing the overall
Pool Balance and thus the amount of Principal Collections. See "DESCRIPTION OF
THE CERTIFICATES-Optional Retransfers of Mortgage Loans to the Transferor."


                                      S-42
<PAGE>   44

      All of the Mortgage Loans may be prepaid in full or in part at any time
without penalty. The prepayment experience with respect to the Mortgage Loans
will affect the weighted average life of the Certificates.

      The rate of prepayment on the Mortgage Loans cannot be predicted. Neither
the Depositor nor the Servicer is aware of any publicly available studies or
statistics on the rate of prepayment of mortgage loans such as the Mortgage
Loans. Generally, home equity revolving credit lines are not viewed by borrowers
as permanent financing. Accordingly, the Mortgage Loans may experience a higher
rate of prepayment than traditional first mortgage loans. On the other hand,
because the Mortgage Loans amortize as described herein, rates of principal
payment on the Mortgage Loans will generally be slower than those of traditional
fully-amortizing first mortgages in the absence of prepayments on such Mortgage
Loans. The prepayment experience of the Trust with respect to the Mortgage Loans
may be affected by a wide variety of factors, including general economic
conditions, prevailing interest rate levels, the availability of alternative
financing, homeowner mobility, the frequency and amount of any future draws on
the Credit Line Agreements and changes affecting the deductibility for Federal
income tax purposes of interest payments on home equity credit lines.
Substantially all of the Mortgage Loans contain "due-on-sale" provisions, and
the Servicer intends to enforce such provisions, unless such enforcement is not
permitted by applicable law. The enforcement of a "due-on-sale" provision will
have the same effect as a prepayment of the related Mortgage Loan. See "CERTAIN
LEGAL ASPECTS OF LOANS-'Due-on-Sale' Clauses" in the Prospectus.

      The yield to an investor who purchases the Certificates in the secondary
market at a price other than par will vary from the anticipated yield if the
rate of prepayment on the Mortgage Loans is actually different than the rate
anticipated by such investor at the time such Certificates were purchased.

      Collections on the Mortgage Loans may vary because, among other things,
borrowers may make payments during any month as low as the minimum monthly
payment for such month or as high as the entire outstanding principal balance
plus accrued interest and the fees and charges thereon. It is possible that
borrowers may fail to make scheduled payments. Collections on the Mortgage Loans
may vary due to seasonal purchasing and payment habits of borrowers.

      No assurance can be given as to the level of prepayments that will be
experienced by the Trust and it can be expected that a portion of borrowers will
not prepay their Mortgage Loans to any significant degree. See "DESCRIPTION OF
THE SECURITIES-Weighted Average Life of the Certificates" in the Prospectus.

                       POOL FACTOR AND TRADING INFORMATION

      The "Pool Factor" is a seven-digit decimal which the Servicer will compute
monthly expressing the Certificate Principal Balance of the Certificates as of
each Distribution Date (after giving effect to any distribution of principal on
such Distribution Date) as a proportion of the Original Certificate Principal
Balance. On the Closing Date, the Pool Factor will be 1.0000000. See
"DESCRIPTION OF THE CERTIFICATES-Distributions on the Certificates." Thereafter,
the Pool Factor will decline to reflect reductions in the related Certificate
Principal Balance


                                      S-43
<PAGE>   45

resulting from distributions of principal to the Certificates and the Invested
Amount of any unreimbursed Liquidation Loss Amounts.

      Pursuant to the Agreement, monthly reports concerning the Invested Amount,
the Pool Factor and various other items of information will be made available to
the Certificateholders. In addition, within 60 days after the end of each
calendar year, beginning with the ___ calendar year, information for tax
reporting purposes will be made available to each person who has been a
Certificateholder of record at any time during the preceding calendar year. See
"DESCRIPTION OF THE CERTIFICATES-Book-Entry Certificates" and "-Reports to
Certificateholders" herein.

                         DESCRIPTION OF THE CERTIFICATES

      The Certificates will be issued pursuant to the Agreement. The form of the
Agreement has been filed as an exhibit to the Registration Statement of which
this Prospectus Supplement and the Prospectus are a part. The following
summaries describe certain provisions of the Agreement. The summaries do not
purport to be complete and are subject to, and are qualified in their entirety
by reference to, all of the provisions of the Agreement.

General

      The Certificates will be issued in denominations of $1,000 and multiples
of $1 in excess thereof and will evidence specified undivided interests in the
Trust. The property of the Trust will consist of, to the extent provided in the
Agreement: (i) each of the Mortgage Loans that from time to time are subject to
the Agreement (including any Additional Balances arising after the Cut-Off
Date); (ii) collections on the Mortgage Loans received after the Cut-Off Date
(exclusive of payments in respect of accrued interest due on or prior to the
Cut-Off Date); (iii) Mortgaged Properties relating to the Mortgage Loans that
are acquired by foreclosure or deed in lieu of foreclosure; (iv) the Collection
Account and the Distribution Account (excluding net earnings thereon); [(v) the
Policy]; (vi) the Spread Account (for the benefit of the Certificate Insurer and
the Certificateholders); and (vii) an assignment of the Depositor's rights under
the Purchase Agreement. Definitive Certificates (as defined below), if issued,
will be transferable and exchangeable at the corporate trust office of the
Trustee, which will initially act as Certificate Registrar. See "-Book-Entry
Certificates" below. No service charge will be made for any registration of
exchange or transfer of Certificates, but the Trustee may require payment of a
sum sufficient to cover any tax or other governmental charge.

      The aggregate undivided interest in the Trust represented by the
Certificates as of the Closing Date will equal $_________ (the "Original
Invested Amount"), which represents _____% of the Cut-Off Date Pool Balance. The
"Original Certificate Principal Balance" will equal $__________. Following the
Closing Date, the "Invested Amount" with respect to any Distribution Date will
be an amount equal to the Original Invested Amount minus (i) the amount of
Investor Principal Collections previously distributed to Certificateholders, and
minus (ii) an amount equal to the product of the Investor Floating Allocation
Percentage and the Liquidation Loss Amounts (each as defined herein). The
principal amount of the outstanding Certificates (the "Certificate Principal
Balance") on any Distribution Date is equal to the Original Certificate


                                      S-44
<PAGE>   46

Principal Balance minus the aggregate of amounts actually distributed as
principal to the Certificateholders. See "-Distributions on the Certificates"
below. Each Certificate represents the right to receive payments of interest at
the Certificate Rate and payments of principal as described below.

      The Transferor will own the remaining undivided interest in the Mortgage
Loans (the "Transferor Interest"), which is equal to the Pool Balance less the
Invested Amount. The Transferor Interest will initially equal $_________, which
represents approximately _____% of the Cut-Off Date Pool Balance. The Transferor
as of any date is the owner of the Transferor Interest which initially will be
the Seller. In general, the Pool Balance will vary each day as principal is paid
on the Mortgage Loans, liquidation losses are incurred, Additional Balances are
drawn down by borrowers and Mortgage Loans are transferred to the Trust.

      The Transferor has the right to sell or pledge the Transferor Interest at
any time, provided (i) the Rating Agencies (as defined herein) have notified the
Transferor and the Trustee in writing that such action will not result in the
reduction or withdrawal of the ratings assigned to the Certificates, and (ii)
certain other conditions specified in the Agreement are satisfied.

Book-Entry Certificates

      The Certificates will be book-entry Certificates (the "Book-Entry
Certificates"). Persons acquiring beneficial ownership interests in the
Certificates ("Certificate Owners") may elect to hold their Certificates through
the Depository Trust Company ("DTC") in the United States, or Cedel or Euroclear
(in Europe) if they are participants of such systems, or indirectly through
organizations which are participants in such systems. The Book-Entry
Certificates will be issued in one or more certificates which equal the
aggregate principal balance of the 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
depositories which in turn will hold such positions in customers' securities
accounts in the depositories' names on the books of DTC. Citibank will act as
depositary for Cedel and Chemical 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 Certificate
Principal Balances of $1,000 and in multiples of $1 in excess thereof. Except as
described below, no person acquiring a Book-Entry Certificate (each, a
"beneficial owner") will be entitled to receive a physical certificate
representing such Certificate (a "Definitive Certificate"). Unless and until
Definitive Certificates are issued, it is anticipated that the only
"Certificateholder" of the Certificates will be Cede & Co., as nominee of DTC.
Certificate Owners will not be Certificateholders as that term is used in the
Agreement. Certificate Owners are only permitted to exercise 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, 


                                      S-45
<PAGE>   47

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).

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

      Certificate Owners will not receive or be entitled to receive certificates
representing their respective interests in the Certificates, except under the
limited circumstances described below. Unless and until Definitive Certificates
are issued, Certificate Owners who are not Participants may transfer ownership
of Certificates only through Participants and indirect participants by
instructing such Participants and indirect participants to transfer
Certificates, by book-entry transfer, through DTC for the account of the
purchasers of such Certificates, which account is maintained with their
respective Participants. Under the Rules and in accordance with DTC's normal
procedures, transfers of ownership of Certificates will be executed through DTC
and the accounts of the respective Participants at DTC will be debited and
credited. 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 Certificate 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
settlement 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" herein and "GLOBAL
CLEARANCE, SETTLEMENT AND TAX DOCUMENTATION PROCEDURES-Certain U.S. Federal
Income Tax Documentation Requirements" in Annex I hereto.

      Transfers between Participants will occur in accordance with DTC rules.
Transfers between Cedel Participants and Euroclear Participants will occur in
accordance with their respective rules and operating procedures. Cross-market
transfers between persons holding directly or indirectly through DTC, on the one
hand, and directly or indirectly through Cedel Participants or Euroclear
Participants, on the other, will be effected in DTC in accordance with DTC rules
on behalf of the relevant European international clearing system by the Relevant


                                      S-46
<PAGE>   48

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, 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 participating organizations ("Cedel
Participants") and facilitates the clearance and settlement of securities
transactions between Cedel Participants through electronic book-entry changes in
accounts of Cedel Participants, thereby eliminating the need for physical
movement of certificates. Transactions may be settled in Cedel in any of 28
currencies, including United States dollars. Cedel provides to its Cedel
Participants, among other things, services for safekeeping, administration,
clearance and settlement of internationally traded securities and securities
lending and borrowing. Cedel interfaces with domestic markets in several
countries. As a professional depository, Cedel is subject to regulation by the
Luxembourg Monetary Institute. Cedel participants are recognized financial
institutions around the world, including underwriters, securities brokers and
dealers, banks, trust companies, clearing corporations and certain other
organizations. Indirect access to Cedel is also available to others, such as
banks, brokers, dealers and trust companies that clear through or maintain a
custodial relationship with a Cedel Participant, either directly or indirectly.

      Euroclear was created in 1968 to hold securities for participants of
Euroclear ("Euroclear Participants") and to clear and settle transactions
between Euroclear Participants through simultaneous electronic book-entry
delivery against payment, thereby eliminating the need for physical movement of
certificates and any risk from lack of simultaneous transfers of securities and
cash. Transactions may now be settled in any of 32 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


                                      S-47
<PAGE>   49

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
Distribution 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 payments 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
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. See "CERTAIN FEDERAL
INCOME TAX CONSEQUENCES-Foreign Investors" and "-Backup Withholding" herein.
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 Servicer 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.


                                      S-48
<PAGE>   50

      DTC has advised the Transferor and 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 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
other action permitted to be taken by a Certificateholder under the Agreement on
behalf of a Cedel Participant or Euroclear Participant only in accordance with
its relevant rules and procedures and subject to the ability of the Relevant
Depositary to effect such actions on its behalf through DTC. DTC may take
actions, at the direction of the related Participants, with respect to some
Certificates which conflict with actions taken with respect to other
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 Transferor advises the Trustee in writing that DTC is no longer willing,
qualified or able to discharge properly its responsibilities as nominee and
depository with respect to the Book-Entry Certificates and the Transferor or the
Trustee is unable to locate a qualified successor, (b) the Transferor, at its
sole option, elects to terminate a book-entry system through DTC or (c) after
the occurrence of an Event of Servicing Termination (as defined herein),
beneficial owners having Percentage Interests aggregating not less than 51 % of
the Certificate Principal Balance of the Book-Entry Certificates advise the
Trustee and DTC through the Financial Intermediaries and the DTC participants 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, and thereafter
the Trustee will recognize the holders of such Definitive Certificates as
Certificateholders under the 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.

Assignment of Mortgage Loans

      At the time of issuance of the Certificates, the Depositor will transfer
to the Trust all of its right, title and interest in and to each Mortgage Loan
(including any Additional Balances arising in the future), related Credit Line
Agreements, mortgages and other related documents (collectively, the "Related
Documents"), including all collections received on or with respect to each such
Mortgage Loan after the Cut-Off Date (exclusive of payments in respect of
accrued interest due on or prior to the Cut-Off Date). The Trustee, concurrently
with such transfer, will deliver the Certificates to the Depositor and the
Transferor Certificate (as defined in the Agreement) to the Transferor. Each
Mortgage Loan transferred to the Trust will be identified on a schedule (the
"Mortgage Loan Schedule") delivered to the Trustee pursuant to the Agreement.


                                      S-49
<PAGE>   51

Such schedule will include information as to the Cut-Off Date Principal Balance
of each Mortgage Loan, as well as information with respect to the Loan Rate.

      The Agreement will permit the Seller to maintain possession of the Related
Documents and certain other documents relating to the Mortgage Loans (the
"Mortgage Files") and assignments of the related mortgages to the Trustee will
not be required to be recorded for so long as the long-term senior unsecured
debt of Bank One is rated at least "____" by _________ and "____" by______. In
the event that the Bank One long-term senior unsecured debt rating does not
satisfy the above-described standards (an "Assignment Event"), Bank One will
have 90 days to record assignments of the mortgages for each such Mortgage Loan
in favor of the Trustee and will have 60 days to deliver the Mortgage File
pertaining to each such Mortgage Loan to the Trustee (unless opinions of counsel
satisfactory to the Rating Agencies and the Certificate Insurer to the effect
that recordation of such assignments or delivery of such documentation is not
required in the relevant jurisdiction to protect the interest of Bank One and
the Trustee in the Mortgage Loans). In lieu of delivery of original
documentation, Bank One may deliver documents which have been imaged optically
upon delivery of an opinion of counsel that (i) such documents do not impair the
enforceability of the transfer to the Trust of the Mortgage Loans and (ii) the
optical image of such documents are enforceable in the relevant jurisdictions to
the same extent as the original documents.

      Within 90 days of an Assignment Event, the Trustee will review the
Mortgage Files and if any Related Document is found to be defective in any
material respect and such defect is not cured within 90 days following
notification thereof to the Seller and the Depositor by the Trustee, the Seller
will be obligated to accept the transfer of such Mortgage Loan from the Trust.
Upon such transfer, the Principal Balance of such Mortgage Loan will be deducted
from the Pool Balance, thus reducing the amount of the Transferor Interest. If
the deduction would cause the Transferor Interest to become less than the
Minimum Transferor Interest at such time (a "Transfer Deficiency"), the Seller
will be obligated to either substitute an Eligible Substitute Mortgage Loan or
make a deposit into the Collection Account in the amount (the "Transfer Deposit
Amount") equal to the amount by which the Transferor Interest would be reduced
to less than the Minimum Transferor Interest at such time. Any such deduction,
substitution or deposit, will be considered for the purposes of the Agreement a
payment in full of such Mortgage Loan. Any Transfer Deposit Amount will be
treated as a Principal Collection. No such transfer shall be considered to have
occurred until the required deposit to the Collection Account is actually made.
The obligation of the Seller to accept a transfer of a Defective Mortgage Loan
is the sole remedy regarding any defects in the Mortgage File and Related
Documents available to the Trustee or the Certificateholders.

      An "Eligible Substitute Mortgage Loan" is a mortgage loan substituted by
the Depositor for a Defective Mortgage Loan which must, on the date of such
substitution, (i) have an outstanding Principal Balance (or in the case of a
substitution of more than one Mortgage Loan for a Defective Mortgage Loan, an
aggregate Principal Balance) that is approximately equal to the Transfer
Deficiency relating to such Defective Mortgage Loan; (ii) have a Loan Rate not
less than the Loan Rate of the Defective Mortgage Loan and not more than ____%
in excess of the Loan Rate of such Defective Mortgage Loan; (iii) have a Loan
Rate based on the same Index with adjustments to such Loan Rate made on the same
Interest Rate Adjustment Date as that of the Defective Mortgage Loan; (iv) have
a Margin that is not less than the Margin of the


                                      S-50
<PAGE>   52

Defective Mortgage Loan and not more than ____ basis points higher than the
Margin for the Defective Mortgage Loan; (v) have a mortgage of the same or
higher level of priority as the mortgage relating to the Defective Mortgage
Loan; (vi) have a remaining term to maturity not more than six months earlier
and not more than ____ months later than the remaining term to maturity of the
Defective Mortgage Loan; (vii) comply with each representation and warranty as
to the Mortgage Loans set forth in the Agreement (deemed to be made as of the
date of substitution); (viii) in general, have an original Combined
Loan-to-Value Ratio not greater than that of the Defective Mortgage Loan; and
(ix) satisfy certain other conditions specified in the Agreement. To the extent
the Principal Balance of an Eligible Substitute Mortgage Loan is less than the
Principal Balance of the related Defective Mortgage Loan and to the extent that
the Transferor Interest would be reduced below the Minimum Transferor Interest,
the Seller will be required to make a deposit to the Collection Account equal to
such difference.

      The Seller will make certain representations and warranties as to the
accuracy in all material respects of certain information furnished to the
Trustee with respect to each Mortgage Loan (e.g., Cut-Off Date Principal Balance
and the Loan Rate). In addition, the Seller will represent and warrant on the
Closing Date that at the time of transfer to the Depositor, the Seller has
transferred or assigned all of its rights, title and interest in or granted a
security interest in each Mortgage Loan and the Related Documents, free of any
lien (subject to certain exceptions). Upon discovery of a breach of any such
representation and warranty which materially and adversely affects the interests
of the Certificateholders or the Certificate Insurer in the related Mortgage
Loan and Related Documents, the Seller will have a period of 90 days after
discovery or notice of the breach to effect a cure. If the breach cannot be
cured within the 90-day period, the Seller will be obligated to accept a
transfer of the Defective Mortgage Loan from the Trust. The same procedure and
limitations that are set forth in the second preceding paragraph for the
transfer of Defective Mortgage Loans will apply to the transfer of a Mortgage
Loan that is required to be transferred because of such breach of a
representation or warranty in the Agreement that materially and adversely
affects the interests of the Certificateholders.

      Mortgage Loans required to be transferred to the Seller as described in
the preceding paragraphs are referred to as "Defective Mortgage Loans."

      Pursuant to the Agreement, the Servicer will service and administer the
Mortgage Loans as more fully set forth above.

Amendments to Credit Line Agreements

      Subject to applicable law, the Servicer may change the terms of the Credit
Line Agreements at any time provided that such changes (i) do not adversely
affect the interest of the Certificateholders or the Certificate Insurer, and
(ii) are consistent with prudent business practice. In addition, the Agreement
permits the Servicer, within certain limitations described therein, to increase
or reduce the Credit Limit of the related Mortgage Loan and increase or reduce
the Margin for such Mortgage Loan.

Optional Transfers of Mortgage Loans to the Transferor

      Subject to the conditions specified in the Agreement, on any Distribution
Date the Transferor may, but shall not be obligated to, remove on such
Distribution Date (the "Transfer Date") from the Trust, certain Mortgage Loans
without notice to the Certificateholders. The Transferor is permitted to
randomly designate the Mortgage Loans to be removed. Mortgage Loans so
designated will only be removed upon satisfaction of certain conditions
specified in the Agreement, including: (i) the Transferor Interest as of such
Transfer Date (after giving effect to such removal) exceeds the Minimum
Transferor Interest; (ii) the Transferor shall have delivered to the Trustee a
"Mortgage Loan Schedule" containing a list of all Mortgage Loans remaining in
the Trust after such removal; (iii) the Transferor shall represent and warrant
that no selection procedures which the Transferor reasonably believes are
adverse to the interests of the Certificateholders [or the Certificate Insurer]
were used by the Transferor in selecting such Mortgage Loans; (iv) in connection
with the first such retransfer of Mortgage Loans, the Rating Agencies shall have
been notified of the proposed transfer and prior to the Transfer Date the Rating
Agencies shall have notified the Transferor in writing that such transfer will
not result in a reduction or withdrawal of the ratings assigned to the
Certificates [without regard to the Policy;] and (v) the Transferor shall have
delivered to the Trustee [and the Certificate Insurer] an officer's certificate
confirming the conditions set forth in clauses (i) through (iii) above. (Section
2.06)

      As of any date of determination, the "Minimum Transferor Interest" is an
amount equal to the lesser of (a) ____% of the Pool Balance on such date and (b)
the Transferor Interest as of the Closing Date.

Payments on Mortgage Loans; Deposits to Collection Account

      The Trustee shall establish and maintain on behalf of the Servicer an
account (the "Collection Account") for the benefit of the Certificateholders and
the Transferor, as their interests may appear. The Collection Account will be an
Eligible Account (as defined herein). Subject to the investment provision
described in the following paragraphs, within two days of receipt by the
Servicer of amounts in respect of the Mortgage Loans (excluding amounts
representing the Servicing Fee, administrative charges, annual fees, taxes,
assessments, credit insurance charges, insurance proceeds to be applied to the
restoration or repair of a Mortgaged Property or similar items), the Servicer
will deposit such amounts in the Collection Account. Not later than the third
Business Day prior to each Distribution Date (the "Determination Date"), the
Servicer will notify the Trustee of the amount of such deposit to be included in
funds available for the related Distribution Date. Notwithstanding the
foregoing, under the terms of the Agreement, so long as Bank One's short-term
obligations are rated at least "____" by Standard & Poor's and "____" by
Moody's, all amounts collected in respect of the Mortgage Loans will be
commingled with the general collections of the Servicer and amounts collected
for a Collection Period will not be required to be deposited into the Collection
Account until one Business Day prior to the related Distribution Date. Amounts
so deposited may be invested in Eligible Investments (as described in the
Agreement) maturing no later than one Business Day prior to the date on which
the amount on deposit therein is required to be deposited in the 


                                      S-52
<PAGE>   54

Collection Account or on such Distribution Date if approved by the Rating
Agencies and the Certificate Insurer.

      An "Eligible Account" is an account that is (i) maintained with a
depository institution whose debt obligations at the time of any deposit therein
have the highest short-term debt rating by the Rating Agencies, (ii) one or more
accounts with a depository institution which accounts are fully insured by
either the Savings Association Insurance Fund ("SAIF") or the Bank Insurance
Fund ("BIF") of the Federal Deposit Insurance Corporation established by such
fund with a minimum long-term unsecured debt rating of "____" by _____ and
"____" by __________, (iii) a segregated trust account maintained with the
Trustee or an Affiliate of the Trustee in its fiduciary capacity or (iv)
otherwise acceptable to each Rating Agency and the Certificate Insurer as
evidenced by a letter from each Rating Agency and the Certificate Insurer to the
Trustee, without reduction or withdrawal of their then current ratings of the
Certificates.

      Eligible Investments are specified in the Agreement and are limited to
investments which meet the criteria of the Rating Agencies from time to time as
being consistent with their then current ratings of the Certificates.

Allocations and Collections

      All collections on the Mortgage Loans will generally be allocated in
accordance with the Credit Line Agreements between amounts collected in respect
of interest and amounts collected in respect of principal. As to any
Distribution Date, "Interest Collections" will be equal to the amounts collected
during the related Collection Period, including such portion of Net Liquidation
Proceeds, allocated to interest pursuant to the terms of the Credit Line
Agreements less Servicing Fees for the related Collection Period.

      As to any Distribution Date, "Principal Collections" will be equal to the
sum of (i) the amounts collected during the related Collection Period, including
such portion of Net Liquidation Proceeds allocated to principal pursuant to the
terms of the Credit Line Agreements and (ii) any Transfer Deposit Amounts. "Net
Liquidation Proceeds" with respect to a Mortgage Loan are equal to the
Liquidation Proceeds, reduced by related expenses, but not including the
portion, if any, of such amount that exceeds the Principal Balance of the
Mortgage Loan plus accrued and unpaid interest thereon to the end of the
Collection Period during which such Mortgage Loan became a Liquidated Mortgage
Loan. "Liquidation Proceeds" ire the proceeds (excluding any amounts drawn on
the Policy) received in connection with the liquidation of any Mortgage Loan,
whether through trustee's sale, foreclosure sale or otherwise.

      With respect to any Distribution Date, the portion of Interest Collections
allocable to the Certificates ("Investor Interest Collections") will equal the
product of (a) Interest Collections for such Distribution Date and (b) the
Investor Floating Allocation Percentage. With respect to any Distribution Date,
the "Investor Floating Allocation Percentage" is the percentage equivalent of a
fraction determined by dividing the Invested Amount at the close of business on
the preceding Distribution Date (or the Closing Date in the case of the first
Distribution Date) by the Pool Balance at the beginning of the related
Collection Period. The remaining amount of Interest Collections will be
allocated to the Transferor Interest.


                                      S-53
<PAGE>   55

      Principal Collections will be allocated between the Certificateholders and
the Transferor ("Investor Principal Collections" and "Transferor Principal
Collections", respectively) as described herein.

      The Trustee will deposit any amounts drawn under the Policy into the
Collection Account.

      With respect to any date, the "Pool Balance" will be equal to the
aggregate of the Principal Balances of all Mortgage Loans as of such date. The
Principal Balance of a Mortgage Loan (other than a Liquidated Mortgage Loan) on
any day is equal to the Cut-Off Date Principal Balance thereof, plus (i) any
Additional Balances in respect of such Mortgage Loan minus (ii) all collections
credited against the Principal Balance of such Mortgage Loan in accordance with
the related Credit Line Agreement prior to such day. The Principal Balance of a
Liquidated Mortgage Loan after final recovery of related Liquidation Proceeds
shall be zero.

Distributions on the Certificates

      Beginning with the first Distribution Date (which will occur on _____ 15,
199_), distributions on the Certificates will be made by the Trustee or the
Paying Agent on each Distribution Date to the persons in whose names such
Certificates are registered at the close of business on the day prior to each
Distribution Date or, if the Certificates are no longer Book-Entry Certificates,
at the close of business on the last day of the month preceding such
Distribution Date (the "Record Date"). The term "Distribution Date" means the
fifteenth day of each month or, if such day is not a Business Day, then the next
succeeding Business Day. Distributions will be made by check or money order
mailed (or upon the request of a Certificateholder owning Certificates having
denominations aggregating at least $1,000,000, by wire transfer or otherwise) to
the address of the person entitled thereto (which, in the case of Book-Entry
Certificates, will be DTC or its nominee) as it appears on the Certificate
Register in amounts calculated as described herein on the Determination Date.
However, the final distribution in respect of the Certificates will be made only
upon presentation and surrender thereof at the office or the agency of the
Trustee specified in the notice to Certificateholders of such final
distribution. For purposes of the Agreement, a "Business Day" is any day other
than (i) a Saturday or Sunday or (ii) a day on which banking institutions in the
States of Ohio, _______ or _______ are required or authorized by law to be
closed.

      Application of Interest Collections. On each Distribution Date, the
Trustee or the Paying Agent will apply the Investor Interest Collections in the
following manner and order of priority:

      (i) as payment to the Trustee for its fee for services rendered pursuant
to the Agreement;

      (ii) as payment for the premium for the Policy;

      (iii) as payment for the accrued interest due and any overdue accrued
interest (with interest thereon to the extent permitted by law) on the
Certificate Principal Balance of the Certificates;


                                      S-54
<PAGE>   56

      (iv) to pay Certificateholders the Investor Loss Amount for such
Distribution Date;

      (v) as payment for any Investor Loss Amount for a previous Distribution
Date that was not previously (a) funded by Investor Interest Collections, (b)
absorbed by the Overcollateralization Amount, (c) funded by amounts on deposit
in the Spread Account or (d) funded by draws on the Policy;

      (vi) to reimburse prior draws made from the Policy (with interest
thereon);

      (vii) to pay principal on the Certificates until the Invested Amount
exceeds the Certificate Principal Balance by the Required Overcollateralization
Amount (such amount so paid, the "Accelerated Principal Distribution Amount");

      (viii)any other amounts required to be deposited in an account for the
benefit of the Certificate Insurer and the Certificateholders or owed to the
Certificate Insurer pursuant to the Insurance Agreement;

      (ix) certain amounts that may be required to be paid to the Servicer
pursuant to the Agreement; and

      (x) to the Transferor to the extent permitted as described herein.

      Payments to Certificateholders pursuant to clause (iii) will be interest
payments on the Certificates. Payments to Certificateholders pursuant to clauses
(iv), (v) and (vii) will be principal payments on the Certificates and will
reduce the Certificate Principal Balance; however, payments pursuant to clause
(vii) will not reduce the Invested Amount. The Accelerated Principal
Distribution Amount is not guaranteed by the Policy.

      To the extent that Investor Interest Collections are applied to pay the
interest on the Certificates, Investor Interest Collections may be insufficient
to cover Investor Loss Amounts. If such insufficiency results in the Certificate
Principal Balance exceeding the Invested Amount, a draw will be made on the
Policy in accordance with the terms of the Policy.

      The "Required Overcollateralization Amount" shall be an amount set forth
in the Insurance Agreement. "Liquidation Loss Amount" means with respect to any
Liquidated Mortgage Loan, the unrecovered Principal Balance thereof during the
Collection Period in which such Mortgage Loan became a Liquidated Mortgage Loan,
after giving effect to the Net Liquidation Proceeds received in connection
therewith. The "Investor Loss Amount" shall be the product of the Investor
Floating Allocation Percentage and the aggregate of the Liquidation Loss Amounts
for such Distribution Date.

      A "Liquidated Mortgage Loan" means, as to any Distribution Date, any
Mortgage Loan in respect of which the Servicer has determined, based on the
servicing procedures specified in the Agreement, as of the end of the preceding
Collection Period that all Liquidation Proceeds which it expects to recover with
respect to the disposition of the related Mortgaged Property have been
recovered. The Investor Loss Amount will be allocated to the Certificateholders.


                                      S-55
<PAGE>   57

      As to any Distribution Date other than the first Distribution Date, the
"Collection Period" is the calendar month preceding each Distribution Date. As
to the first Distribution Date, the "Collection Period" is the period beginning
on the day after the Cut-Off Date and ending on __________, 199_.

      Interest will be distributed on each Distribution Date at the Certificate
Rate for the related Interest Period (as defined below). The "Certificate Rate"
for a Distribution Date will generally equal the sum of (a) LIBOR, determined as
specified herein, as of the second LIBOR Business Day prior to the immediately
preceding Distribution Date (or as of two LIBOR Business Days prior to the
Closing Date, in the case of the first Distribution Date) plus (b) % per annum.
Notwithstanding the foregoing, in no event will the amount of interest required
to be distributed in respect of the Certificates on any Distribution Date exceed
a rate equal to the weighted average of the Loan Rates (net of the Servicing Fee
Rate, the fee payable to the Trustee and the rate at which the premium payable
to the Certificate Insurer is calculated) weighted on the basis of the daily
balance of each Mortgage Loan during the related billing cycle prior to the
Collection Period relating to such Distribution Date or in the case of the first
Distribution Date, the weighted average loan rate as of the Cut-Off Date.

      Interest on the Certificates in respect of any Distribution Date will
accrue on the Certificate Principal Balance from the preceding Distribution Date
(or in the case of the first Distribution Date, from the date of the initial
issuance of the Certificates (the "Closing Date")) through the day preceding
such Distribution Date (each such period, an "Interest Period") on the basis of
the actual number of days in the Interest Period and a 360-day year. Interest
payments on the Certificates will be funded from Investor Interest Collections
[and, if necessary, from draws on the Policy]. Interest for any Distribution
Date due but not paid on such Distribution Date will be due on the next
succeeding Distribution Date together with additional interest on such amount at
a rate equal to the sum of the applicable Certificate Rate and 2% per annum.

      Calculation of the LIBOR Rate. On each Distribution Date, LIBOR shall be
established by the Trustee and as to any Interest Period, LIBOR will equal the
rate for United States dollar deposits for one month which appears on the
Telerate Screen Page 3750 as of 11:00 A.M., London time, on the second LIBOR
Business Day prior to the first day of such Interest Period. "Telerate Screen
Page 3750" means the display designated as page 3750 on the Telerate Service (or
such other page as may replace page 3750 on that service for the purpose of
displaying London interbank offered rates of major banks). If such rate does not
appear on such page (or such other page as may replace that page on that
service, or if such service is no longer offered, such other service for
displaying LIBOR or comparable rates as may be selected by the Depositor after
consultation with the Trustee), the rate will be the Reference Bank Rate. The
"Reference Bank Rate" will be determined on the basis of the rates at which
deposits in U.S. Dollars are offered by the reference banks (which shall be
three major banks that are engaged in transactions in the London interbank
market, selected by the Depositor after consultation with the Trustee) as of
11:00 A.M., London time, on the day that is two LIBOR Business Days prior to the
immediately preceding Distribution Date to prime banks in the London interbank
market for a period of one month in amounts approximately equal to the principal
amount of the Certificates then outstanding. The Trustee will request the
principal London office of each of the reference banks to provide a quotation of
its rate. If at least two such quotations are provided, the rate will be the
arithmetic mean of the quotations. If on such date fewer than two quotations


                                      S-56
<PAGE>   58

are provided as requested, the rate will be the arithmetic mean of the rates
quoted by one or more major banks in New York City, selected by the Depositor
after consultation with the Trustee, as of 11:00 A.M., New York City time, on
such date for loans in U.S. Dollars to leading European banks for a period of
one month in amounts approximately equal to the principal amount of the
Certificates then outstanding. If no such quotations can be obtained, the rate
will be LIBOR for the prior Distribution Date. "LIBOR Business Day" means any
day other than (i) a Saturday or a Sunday or (ii) a day on which banking
institutions in the State of New York or in the city of London, England are
required or authorized by law to be closed.

      Transferor Collections. Collections allocable to the Transferor Interest
will be distributed to the Transferor only to the extent that such distribution
will not reduce the amount of the Transferor Interest as of the related
Distribution Date below the Minimum Transferor Interest. Amounts not distributed
to the Transferor because of such limitations will be retained in the Collection
Account until the Transferor Interest exceeds the Minimum Transferor Interest,
at which time such excess shall be released to the Transferor.

      Overcollateralization. The distribution of the aggregate Accelerated
Principal Distribution Amount, if any, to Certificateholders may result in the
Invested Amount being greater than the Certificate Principal Balance, thereby
creating overcollateralization. The Overcollateralization Amount, if any, will
be available to absorb any Investor Loss Amount that is not covered by Investor
Interest Collections.

      Distributions of Principal Collections. For the period beginning on the
first Distribution Date and, unless a Rapid Amortization Event shall have
earlier occurred, ending immediately after the Distribution Date in _____ 200_
(the "Managed Amortization Period"), the amount of Principal Collections payable
to Certificateholders as of each Distribution Date during the Managed
Amortization Period will equal, to the extent funds are available therefor, the
Scheduled Principal Collections Distribution Amount for such Distribution Date.
On any Distribution Date during the Managed Amortization Period, the "Scheduled
Principal Collections Distribution Amount" shall equal the lesser of (i) the
Maximum Principal Payment (as defined below) and (ii) the Alternative Principal
Payment (as defined herein). With respect to any Distribution Date, the "Maximum
Principal Payment" will equal the product of the Investor Fixed Allocation
Percentage and Principal Collections for such Distribution Date. With respect to
any Distribution Date, the "Alternative Principal Payment" will equal the
amount, but not less than zero, of Principal Collections for such Distribution
Date less the aggregate of Additional Balances created during the related
Collection Period. The "Rapid Amortization Period" is the period beginning at
the earlier of (i) the occurrence of a Rapid Amortization Event and (ii)
immediately following the _____ 200_ Distribution Date and continuing until the
earlier of when (i) the Certificate Principal Balance has been reduced to zero
and (ii) the Trust is terminated. See "-Termination; Retirement of the
Certificates."

      Beginning with the first Distribution Date of the Rapid Amortization
Period, the amount of Principal Collections payable to Certificateholders on
each Distribution Date will be equal to the Maximum Principal Payment.

      Distributions of Principal Collections based upon the Investor Fixed
Allocation Percentage may result in distributions of principal to
Certificateholders in amounts that are


                                      S-57
<PAGE>   59

greater relative to the declining Pool Balance than would be the case if the
Investor Floating Allocation Percentage were used to determine the percentage of
Principal Collections distributed in respect of the Invested Amount. Principal
Collections not allocated to the Certificateholders will be allocated to the
Transferor Interest. The aggregate distributions of principal to the
Certificateholders will not exceed the Original Certificate Principal Balance.

      In addition, to the extent of funds available therefor (including funds
available under the Policy), on the Distribution Date in _____ 20__,
Certificateholders will be entitled to receive as a payment of principal an
amount equal to the outstanding Certificate Principal Balance.

      The Paying Agent. The Paying Agent shall initially be the Trustee,
together with any successor thereto in such capacity (the "Paying Agent"). The
Paying Agent shall have the revocable power to withdraw funds from the
Collection Account for the purpose of making distributions to the
Certificateholders.

Rapid Amortization Events

      As described above, the Rapid Amortization Period will commence if a Rapid
Amortization Event occurs. "Rapid Amortization Event" refers to any of the
following events:

            (a) failure on the part of the Seller (i) to make a payment or
      deposit required under the Agreement within three Business Days after the
      date such payment or deposit is required to be made or (ii) to observe or
      perform in any material respect any other covenants or agreements of the
      Seller set forth in the Agreement, which failure continues unremedied for
      a period of 60 days after written notice;

            (b) any representation or warranty made by the Seller in the
      Agreement proves to have been incorrect in any material respect when made
      and continues to be incorrect in any material respect for a period of 60
      days after written notice and as a result of which the interests of the
      Certificateholders are materially and adversely affected; provided,
      however, that a Rapid Amortization Event shall not be deemed to occur if
      the Seller has purchased or made a substitution for the related Mortgage
      Loan or Mortgage Loans if applicable during such period (or within an
      additional 60 days with the consent of the Trustee) in accordance with the
      provisions of the Agreement;

            (c) the occurrence of certain events of bankruptcy, insolvency or
      receivership relating to the Transferor;

            (d) the Trust becomes subject to regulation by the Securities and
      Exchange Commission as an investment company within the meaning of the
      Investment Company Act of 1940, as amended; or (e) the aggregate of all
      draws under the Policy exceeds 1% of the Cut-Off Date Pool Balance.

      In the case of any event described in clause (a) or (b), a Rapid
Amortization Event will be deemed to have occurred only if, after the applicable
grace period, if any, described in such clauses, either the Trustee or
Certificateholders holding Certificates evidencing more than 51% of the
Percentage Interests [or the Certificate Insurer (so long as there is no default
by the


                                      S-58
<PAGE>   60

Certificate Insurer in the performance of its obligations under the Policy)], by
written notice to the Depositor, the Transferor and the Servicer (and to the
Trustee, if given by the Certificateholders) declare that a Rapid Amortization
Event has occurred as of the date of such notice. In the case of any event
described in clause (c), (d) or (e), a Rapid Amortization Event will be deemed
to have occurred without any notice or other action on the part of the Trustee
or the Certificateholders immediately upon the occurrence of such event.

      In addition to the consequences of a Rapid Amortization Event discussed
above, if the Transferor voluntarily files a bankruptcy petition or goes into
liquidation or any person is appointed a receiver or bankruptcy trustee of the
Transferor, on the day of any such filing or appointment no further Additional
Balances will be transferred to the Trust, the Transferor will immediately cease
to transfer Additional Balances to the Trust and the Transferor will promptly
give notice to the Trustee of any such filing or appointment. Within 15 days,
the Trustee will publish a notice of the liquidation or the filing or
appointment stating that the Trustee intends to sell, dispose of or otherwise
liquidate the Mortgage Loans in a commercially reasonable manner and to the best
of its ability. Unless otherwise instructed within a specified period by
Certificateholders representing undivided interests aggregating more than 51% of
the aggregate principal amount of the Certificates, the Trustee will sell,
dispose of or otherwise liquidate the Mortgage Loans in a commercially
reasonable manner and on commercially reasonable terms. Any proceeds will be
treated as collections allocable to the Certificateholders and the Investor
Fixed Allocation Percentage of such remaining proceeds and will be distributed
to the Certificateholders on the date such proceeds are received (the
"Dissolution Distribution Date"). If the portion of such proceeds allocable to
the Certificateholders are not sufficient to pay in full the remaining amount
due on the Certificates, the Policy will cover such shortfall.

      Notwithstanding the foregoing, if a conservator, receiver or
trustee-in-bankruptcy is appointed for the Transferor and no Rapid Amortization
Event exists other than such conservatorship, receivership or insolvency of the
Transferor, the conservator, receiver or trustee-in-bankruptcy may have the
power to prevent the commencement of the Rapid Amortization Period or the sale
of Mortgage Loans described above.

The Policy

                         [describe Policy if applicable]

      On or before the Closing Date, the Policy will be issued by the
Certificate Insurer pursuant to the provisions of the Agreement and the
Insurance and Indemnity Agreement (the "Insurance Agreement") to be dated as of
_________, 199_, among Bank One, the Depositor, the Trustee and the Certificate
Insurer.

Reports to Certificateholders

      Concurrently with each distribution to the Certificateholders, the
Servicer will forward to the Trustee for mailing to such Certificateholder a
statement setting forth among other items:

            (i) the Investor Floating Allocation Percentage for the preceding
      Collection Period;


                                      S-59

            (ii) the amount being distributed to Certificateholders;

            (iii) the amount of interest included in such distribution and the
      related Certificate Rate;

      such distribution (and the amount of interest thereon);

            (v) the amount, if any, of the remaining overdue accrued interest
      after giving effect to such distribution;

            (vi) the amount, if any, of principal included in such distribution;

            (vii) the amount, if any, of the reimbursement of previous
      Liquidation Loss Amounts included in such distribution;

            (viii)the amount, if any, of the aggregate unreimbursed Liquidation
      Loss Amounts after giving effect to such distribution;

            (ix) the Servicing Fee for such Distribution Date;

            (x) the Invested Amount and the Certificate Principal Balance, each
      after giving effect to such distribution;

            (xi) the Pool Balance as of the end of the preceding Collection
      Period;

            (xii) the number and aggregate Principal Balances of the Mortgage
      Loans as to which the minimum monthly payment is delinquent for 30-59
      days, 60-89 days and 90 or more days, respectively, as of the end of the
      preceding Collection Period;

            (xiii)the book value of any real estate which is acquired by the
      Trust through foreclosure or grant of deed in lieu of foreclosure; and

            (xiv) the amount of any draws on the Policy.

      In the case of information furnished pursuant to clauses (iii), (iv), (v),
(vi), (vii) and (viii) above, the amounts shall be expressed as a dollar amount
per Certificate with a $1,000 denomination.

      Each year commencing in 1997, the Servicer will be required to forward to
the Trustee a statement containing the information set forth in clauses (iii)
and (vi) above aggregated for such calendar year.

Collection and Other Servicing Procedures on Mortgage Loans

      The Servicer will make reasonable efforts to collect all payments called
for under the Mortgage Loans and will, consistent with the Agreement, follow
such collection procedures as it follows from time to time with respect to the
home equity loans in its servicing portfolio


                                      S-60
<PAGE>   62

comparable to the Mortgage Loans. Consistent with the above, the Servicer may in
its discretion waive any late payment charge or any assumption or other fee or
charge that may be collected in the ordinary course of servicing the Mortgage
Loans.

      With respect to the Mortgage Loans, the Servicer may arrange with a
borrower a schedule for the payment of interest due and unpaid for a period,
provided that any such arrangement is consistent with the Servicer's policies
with respect to the home equity mortgage loans it owns or services. In
accordance with the terms of the Agreement, the Servicer may consent under
certain circumstances to the placing of a subsequent senior lien in respect of a
Mortgage Loan.

Hazard Insurance

      The Agreement provides that the Servicer maintain certain hazard insurance
on the Mortgaged Properties relating to the Mortgage Loans. While the terms of
the related Credit Line Agreements generally require borrowers to maintain
certain hazard insurance, the Servicer will not monitor the maintenance of such
insurance.

      The Agreement requires the Servicer to maintain for any Mortgaged Property
relating to a Mortgage Loan acquired upon foreclosure of a Mortgage Loan, or by
deed in lieu of such foreclosure, hazard insurance with extended coverage in an
amount equal to the lesser of (a) the maximum insurable value of such Mortgaged
Property or (b) the outstanding balance of such Mortgage Loan plus the
outstanding balance on any mortgage loan senior to such Mortgage Loan at the
time of foreclosure or deed in lieu of foreclosure, plus accrued interest and
the Servicer's good faith estimate of the related liquidation expenses to be
incurred in connection therewith. The Agreement provides that the Servicer may
satisfy its obligation to cause hazard policies to be maintained by maintaining
a blanket policy insuring against losses on such Mortgaged Properties. If such
blanket policy contains a deductible clause, the Servicer will be obligated to
deposit in the Collection Account the sums which would have been deposited
therein but for such clause. (Section 3.04) The Servicer will initially satisfy
these requirements by maintaining a blanket policy. As set forth above, all
amounts collected by the Servicer (net of any reimbursements to the Servicer)
under any hazard policy (except for amounts to be applied to the restoration or
repair of the Mortgaged Property) will ultimately be deposited in the Collection
Account.

      In general, the standard form of fire and extended coverage policy covers
physical damage to or destruction of the improvements on the property by fire,
lightning, explosion, smoke, windstorm and hail, and the like, strike and civil
commotion, subject to the conditions and exclusions specified in each policy.
Although the policies relating to the Mortgage Loans will be underwritten by
different insurers and therefore will not contain identical terms and
conditions, the basic terms thereof are dictated by state laws and most of such
policies typically do not cover any physical damage resulting from the
following: war, revolution, governmental actions, floods and other water-related
causes, earth movement (including earthquakes, landslides and mudflows), nuclear
reactions, wet or dry rot, vermin, rodents, insects or domestic animals, theft
and, in certain cases vandalism. The foregoing list is merely indicative of
certain kinds of uninsured risks and is not intended to be all-inclusive or an
exact description of the insurance policies relating to the Mortgaged
Properties.

<PAGE>   63

Realization Upon Defaulted Mortgage Loans

      The Servicer will foreclose upon or otherwise comparably convert to
ownership Mortgaged Properties securing such of the Mortgage Loans as come into
default when, in accordance with applicable servicing procedures under the
Agreement, no satisfactory arrangements can be made for the collection of
delinquent payments. In connection with such foreclosure or other conversion,
the Servicer will follow such practices as it deems necessary or advisable and
as are in keeping with its general subordinate mortgage servicing activities,
provided the Servicer will not be required to expend its own funds in connection
with foreclosure or other conversion, correction of default on a related senior
mortgage loan or restoration of any property unless, in its sole judgment, such
foreclosure, correction or restoration will increase Net Liquidation Proceeds.
The Servicer will be reimbursed out of Liquidation Proceeds for advances of its
own funds as liquidation expenses before any Net Liquidation Proceeds are
distributed to Certificateholders or the Transferor.

Servicing Compensation and Payment of Expenses

      With respect to each Collection Period, the Servicer will receive from
interest collections in respect of the Mortgage Loans a portion of such interest
collections as a monthly Servicing Fee in the amount equal to approximately
_____% per annum ("Servicing Fee Rate") on the aggregate Principal Balances of
the Mortgage Loans as of the first day of the related Collection Period (or at
the Cut-Off Date for the first Collection Period). All assumption fees, late
payment charges and other fees and charges, to the extent collected from
borrowers, will be retained by the Servicer as additional servicing
compensation.

      The Servicer will pay certain ongoing expenses associated with the Trust
and incurred by it in connection with its responsibilities under the Agreement.
In addition, the Servicer will be entitled to reimbursement for certain expenses
incurred by it in connection with defaulted Mortgage Loans and in connection
with the restoration of Mortgaged Properties, such right of reimbursement being
prior to the rights of Certificateholders to receive any related Net Liquidation
Proceeds.

Evidence as to Compliance

      The Agreement provides for delivery on or before May 31 in each year,
beginning in May 31, 1997, to the Trustee of an annual statement signed by an
officer of the Servicer to the effect that the Servicer has fulfilled its
material obligations under the Agreement throughout the preceding fiscal year,
except as specified in such statement.

Certain Matters Regarding the Servicer and the Transferor

      The Agreement provides that the Servicer may not resign from its
obligations and duties thereunder, except in connection with a permitted
transfer of servicing, unless (i) such duties and obligations are no longer
permissible under applicable law or are in material conflict by reason of
applicable law with any other activities of a type and nature presently carried
on by it or its affiliate or (ii) upon the satisfaction of the following
conditions: (a) the Servicer has proposed a


                                      S-62
<PAGE>   64

successor servicer to the Trustee in writing and such proposed successor
servicer is reasonably acceptable to the Trustee; (b) the Rating Agencies have
confirmed to the Trustee that the appointment of such proposed successor
servicer as the Servicer will not result in the reduction or withdrawal of the
then current rating of the Certificates; and (c) such proposed successor
servicer is reasonably acceptable to the Certificate Insurer. No such
resignation will become effective until the Trustee or a successor servicer has
assumed the Servicer's obligations and duties under the Agreement.
Notwithstanding the foregoing, Bank One may transfer its servicing obligations
to any other direct or indirect wholly-owned subsidiary of BANC ONE CORPORATION
or another entity (which meets certain eligibility standards set forth in the
Agreement) and be relieved of its obligations and duties under the Agreement and
related agreements.

      The Servicer may perform any of its duties and obligations under the
Agreement through one or more subservicers or delegates, which may be affiliates
of the Servicer. Notwithstanding any such arrangement, the Servicer will remain
liable and obligated to the Trustee and the Certificateholders for the
Servicer's duties and obligations under the Agreement, without any diminution of
such duties and obligations and as if the Servicer itself were performing such
duties and obligations.

      Any person into which, in accordance with the Agreement, Bank One or the
Servicer may be merged or consolidated or any person resulting from any merger
or consolidation to which Bank One or the Servicer is a party, or any person
succeeding to the business of Bank One or the Servicer, will be the successor to
Bank One as servicer, or the Servicer, as the case may be, under the Agreement.

      The Agreement provides that the Servicer will indemnify the Trust and the
Trustee from and against any loss, liability, expense, damage or injury suffered
or sustained as a result of the Servicer's actions or omissions in connection
with the servicing and administration of the Mortgage Loans which are not in
accordance with the provisions of the Agreement. Under the Agreement, the
Transferor will indemnify an injured party for the entire amount of any losses,
claims, damages or liabilities arising out of or based on the Agreement (other
than losses resulting from defaults under the Mortgage Loans). In the event of
an Event of Servicing Termination (as defined below) resulting in the assumption
of servicing obligations by a successor Servicer, the successor Servicer will
indemnify the Transferor for any losses, claims, damages and liabilities of the
Transferor as described in this paragraph arising from the successor Servicer's
actions or omissions. The Agreement provides that neither the Depositor, the
Transferor nor the Servicer nor their directors, officers, employees or agents
will be under any other liability to the Trust, the Trustee, the
Certificateholders or any other person for any action taken or for refraining
from taking any action pursuant to the Agreement. However, neither the
Depositor, the Transferor nor the Servicer will be protected against any
liability which would otherwise be imposed by reason of willful misconduct, bad
faith or gross negligence of the Depositor, the Transferor or the Servicer in
the performance of its duties under the Agreement or by reason of reckless
disregard of its obligations thereunder. In addition, the Agreement provides
that the Servicer will not be under any obligation to appear in, prosecute or
defend any legal action which is not incidental to its servicing
responsibilities under the Agreement and which in its opinion may expose it to
any expense or liability. The Servicer may, in its sole discretion, undertake
any such legal action which it may deem necessary or desirable


                                      S-63
<PAGE>   65

with respect to the Agreement and the rights and duties of the parties thereto
and the interest of the Certificateholders thereunder.

      Any corporation into which the Servicer may be merged or consolidated, or
any corporation resulting from any merger, conversion or consolidation to which
the Servicer shall be a party, or any corporation succeeding to the business of
the Servicer shall be the successor of the Servicer hereunder, without the
execution or filing of any paper or any further act on the part of any of the
parties hereto, anything in the Agreement to the contrary notwithstanding.

Events of Servicing Termination

      "Events of Servicing Termination" will consist of: (i) any failure by the
Servicer to deposit in the Collection Account any deposit required to be made
under the Agreement, which failure continues unremedied for five Business Days
after the giving of written notice of such failure to the Servicer by the
Trustee, or to the Servicer and the Trustee by the Certificate Insurer or
Certificateholders evidencing an aggregate, undivided interest in the Trust of
at least 25% of the Certificate Principal Balance; (ii) any failure by the
Servicer duly to observe or perform in any material respect any other of its
covenants or agreements in the Agreement which, in each case, materially and
adversely affects the interests of the Certificateholders or the Certificate
Insurer and continues unremedied for 60 days after the giving of written notice
of such failure to the Servicer by the Trustee, or to the Servicer and the
Trustee by the Certificate Insurer or Certificateholders evidencing an
aggregate, undivided interest in the Trust of at least 25% of the Certificate
Principal Balance; or (iii) certain events of insolvency, readjustment of debt,
marshalling of assets and liabilities or similar proceedings relating to the
Servicer and certain actions by the Servicer indicating insolvency,
reorganization or inability to pay its obligations. Under certain other
circumstances, the Certificate Insurer with the consent of holders of Investor
Certificates evidencing an aggregate, undivided interest in the Trust of at
least 51% of the Certificate Principal Balance may deliver written notice to the
Servicer terminating all the rights and obligations of the Servicer under the
Agreement.

      Notwithstanding the foregoing, a delay in or failure of performance
referred to under clause (i) above for a period of ten Business Days or referred
to under clause (ii) above for a period of 60 Business Days, shall not
constitute an Event of Servicing Termination if such delay or failure could not
be prevented by the exercise of reasonable diligence by the Servicer and such
delay or failure was caused by an act of God or other similar occurrence. Upon
the occurrence of any such event the Servicer shall not be relieved from using
its best efforts to perform its obligations in a timely manner in accordance
with the terms of the Agreement and the Servicer shall provide the Trustee, the
Depositor, the Transferor, the Certificate Insurer and the Certificateholders
prompt notice of such failure or delay by it, together with a description of its
efforts to so perform its obligations.

Rights Upon an Event of Servicing Termination

      So long as an Event of Servicing Termination remains unremedied, either
the Trustee, or Certificateholders evidencing an aggregate, undivided interest
in the Trust of at least 51% of the Certificate Principal Balance [or the
Certificate Insurer], may terminate all of the rights and


                                      S-64
<PAGE>   66

obligations of the Servicer under the Agreement and in and to the Mortgage
Loans, whereupon the Trustee will succeed to all the responsibilities, duties
and liabilities of the Servicer under the Agreement and will be entitled to
similar compensation arrangements. In the event that the Trustee would be
obligated to succeed the Servicer but is unwilling or unable so to act, it may
appoint, or petition a court of competent jurisdiction for the appointment of, a
housing and home finance institution or other mortgage loan or home equity loan
servicer with all licenses and permits required to perform its obligations under
the Agreement and having a net worth of at least $__________ [and acceptable to
the Certificate Insurer] to act as successor to the Servicer under the
Agreement. Pending such appointment, the Trustee will be obligated to act in
such capacity unless prohibited by law. Such successor will be entitled to
receive the same compensation that the Servicer would otherwise have received
(or such lesser compensation as the Trustee and such successor may agree). A
receiver or conservator for the Servicer may be empowered to prevent the
termination and replacement of the Servicer where the only Event of Servicing
Termination that has occurred is an Insolvency Event.

Amendment

      The Agreement may be amended from time to time by the Seller, the
Transferor, the Servicer, the Depositor and the Trustee [and with the consent of
the Certificate Insurer], but without the consent of the Certificateholders, to
cure any ambiguity, to correct or supplement any provisions therein which may be
inconsistent with any other provisions of the Agreement, to add to the duties of
the Depositor, the Seller, the Transferor or the Servicer or to add or amend any
provisions of the Agreement as required by the Rating Agencies in order to
maintain or improve any rating of the Certificates (it being understood that,
after obtaining the ratings in effect on the Closing Date, neither the
Transferor, the Trustee nor the Servicer is obligated to obtain, maintain, or
improve any such rating) or to add any other provisions with respect to matters
or questions arising under the Agreement which shall not be inconsistent with
the provisions of the Agreement, provided that such action will not, as
evidenced by an opinion of counsel, materially and adversely affect the
interests of any Certificateholder [or the Certificate Insurer]; provided, that
any such amendment will not be deemed to materially and adversely affect the
Certificateholders and no such opinion will be required to be delivered if the
person requesting such amendment obtains a letter from the Rating Agencies
stating that such amendment would not result in a downgrading of the then
current rating of the Certificates. The Agreement may also be amended from time
to time by the Seller, the Servicer, the Depositor, and the Trustee, with the
consent of Certificateholders evidencing an aggregate, undivided interest in the
Trust of at least 51% of the Certificate Principal Balance [and the Certificate
Insurer] for the purpose of adding any provisions to or changing in any manner
or eliminating any of the provisions of the Agreement or of modifying in any
manner the rights of the Certificateholders, provided that no such amendment
will (i) reduce in any manner the amount of, or delay the timing of, collections
of payments on the Certificates or distributions or payments under the Policy
which are required to be made on any Certificate without the consent of the
holder of such Certificate or (ii) reduce the aforesaid percentage required to
consent to any such amendment, without the consent of the holders of all
Certificates then outstanding.

Termination; Retirement of the Certificates

      The Trust will terminate on the Distribution Date following the later of
(A) payment in full of all amounts owing to the Certificate Insurer and (B) the
earliest of (i) the Distribution Date on which the Certificate Principal Balance
has been reduced to zero, (ii) the final payment or other liquidation of the
last Mortgage Loan in the Trust, (iii) the optional transfer to the Transferor
of the Certificates, as described below and (iv) the Distribution Date in _____
20__.

      The Certificates will be subject to optional transfer to the Transferor on
any Distribution Date after the Certificate Principal Balance is reduced to an
amount less than or equal to _____% of the Original Certificate Principal
Balance and all amounts due and owing to the Certificate Insurer and
unreimbursed draws on the Policy, together with interest thereon, as provided
under the Insurance Agreement, have been paid. The transfer price will be equal
to the sum of the outstanding Certificate Principal Balance and accrued and
unpaid interest thereon at the Certificate Rate through the day preceding the
final Distribution Date. In no event, however, will the Trust created by the
Agreement continue for more than 21 years after the death of certain individuals
named in the Agreement. Written notice of termination of the Agreement will be
given to each Certificateholder, and the final distribution will be made only
upon surrender and cancellation of the Certificates at an office or agency
appointed by the Trustee which will be specified in the notice of termination.

      In addition, the Trust may be liquidated as a result of certain events of
bankruptcy, insolvency or receivership relating to the Transferor. See "-Rapid
Amortization Events" herein.

The Trustee

      ___________________________, a ______________________ with its principal
place of business in ______________, has been named Trustee pursuant to the
Agreement.

      The commercial bank or trust company serving as Trustee may own
Certificates and have normal banking [and the Certificate Insurer] and/or their
affiliates. relationships with the Depositor, the Servicer, the Seller [and the
Certificate Insurer] and/or their affiliates.

      The Trustee may resign at any time, in which event the Depositor will be
obligated to appoint a successor Trustee, as approved by the Certificate
Insurer. The Depositor may also remove the Trustee if the Trustee ceases to be
eligible to continue as such under the Agreement or if the Trustee becomes
insolvent. Upon becoming aware of such circumstances, the Depositor will be
obligated to appoint a successor Trustee, as approved by the Certificate
Insurer. Any resignation or removal of the Trustee and appointment of a
successor Trustee will not become effective until acceptance of the appointment
by the successor Trustee.

      No holder of a Certificate will have any right under the Agreement to
institute any proceeding with respect to the Agreement unless such holder
previously has given to the Trustee written notice of default and unless
Certificateholders evidencing an aggregate, undivided interest in the Trust of
at least 51% of the Certificate Principal Balance have made written requests
upon the Trustee to institute such proceeding in its own name as Trustee
thereunder and have offered to the Trustee reasonable indemnity and the Trustee
for 60 days has neglected or


                                      S-66
<PAGE>   68

refused to institute any such proceeding. The Trustee will be under no
obligation to exercise any of the trusts or powers vested in it by the Agreement
or to make any investigation of matters arising thereunder or to institute,
conduct or defend any litigation thereunder or in relation thereto at the
request, order or direction of any of the Certificateholders, unless such
Certificateholders have offered to the Trustee reasonable security or indemnity
against the cost, expenses and liabilities which may be incurred therein or
thereby.

Certain Activities

      The Trust will not: (i) borrow money; (ii) make loans; (iii) invest in
securities for the purpose of exercising control; (iv) underwrite securities;
(v) except as provided in the Agreement, engage in the purchase and sale (or
turnover) of investments; (vi) offer securities in exchange for property (except
Certificates for the Mortgage Loans); or (vii) repurchase or otherwise reacquire

reports as to the compliance by the Servicer with the terms of the Agreement.

                      DESCRIPTION OF THE PURCHASE AGREEMENT

      The Mortgage Loans to be transferred to the Trust by the Depositor will be
purchased by the Depositor from the Seller pursuant to the Purchase Agreement to
be entered into between the Depositor, as purchaser of the Mortgage Loans, and
______________, as Seller of the Mortgage Loans. Under the Purchase Agreement,
the Seller will agree to transfer the Mortgage Loans and related Additional
Balances to the Depositor. Pursuant to the Agreement, the Mortgage Loans will be
immediately transferred by the Depositor to the Trust, and the Depositor will
assign its rights in, to and under the Purchase Agreement to the Trust. The
following summary describes certain terms of the form of the Purchase Agreement
and is qualified in its entirety by reference to the Purchase Agreement.

Transfer of Mortgage Loans

      Pursuant to the Purchase Agreement, the Seller will transfer and assign to
the Depositor, all of its right, title and interest in and to the Mortgage Loans
and all of the Additional Balances thereafter created. The purchase price of the
Mortgage Loans is a specified percentage of the face amount thereof as of the
time of transfer. The purchase price of each Additional Balance comprising the
Principal Balance of a Mortgage Loan is the amount of the related new advance.

Representations and Warranties

      The Seller will represent and warrant to the Depositor that, among other
things, as of the Closing Date, it is duly organized and in good standing and
that it has the authority to consummate the transactions contemplated by the
Purchase Agreement. The Seller will also represent and warrant to the Depositor
that, among other things, immediately prior to the sale of the Mortgage Loans to
the Depositor, the Seller was the sole owner and holder of the Mortgage Loans
free and clear of any and all liens and security interests. The Seller will make
similar representations and warranties in the Agreement. The Seller will also
represent and warrant to the Depositor that, among other things, as of the
Closing Date, (a) the Purchase Agreement


                                      S-67
<PAGE>   69

constitutes a legal, valid and binding obligation of the Seller and (b) the
Purchase Agreement constitutes a valid sale or security interest to the
Depositor of all right, title and interest of the Seller in and to the Mortgage
Loans and the proceeds thereof.

Assignment to Trust

      The Seller expressly acknowledges and consents to the Depositor's transfer
of its rights relating to the Mortgage Loans under the Agreement to the Trust.
The Seller also agrees to perform its obligations under the Purchase Agreement
for the benefit of the Trust.

Termination

      The Purchase Agreement will terminate upon the termination of the Trust.

                                 USE OF PROCEEDS

      The net proceeds to be received from the sale of the Certificates will be
applied by the Depositor towards the purchase of the Mortgage Loans.

                     CERTAIN FEDERAL INCOME TAX CONSEQUENCES

                             [Insert if applicable]

                                   STATE TAXES

      The Depositor makes no representations regarding the tax consequences of
purchase, ownership or disposition of the Certificates under the tax laws of any
state. Investors considering an investment in the Certificates should consult
their own tax advisors regarding such tax consequences.

   All investors should consult their own tax advisors regarding the Federal,
state, local or foreign income tax consequences of the purchase, ownership and
disposition of the Certificates.

                              ERISA CONSIDERATIONS

                             [Insert as applicable]

                         LEGAL INVESTMENT CONSIDERATIONS

      [Although, as a condition to their issuance, the Certificates will be
rated in the highest rating category of the Rating Agencies,] the Certificates
will not constitute "mortgage related securities" for purposes of the Secondary
Mortgage Market Enhancement Act of 1984 ("SMMEA"), because not all of the
Mortgages securing the Mortgage Loans are first mortgages.


                                      S-68
<PAGE>   70

Accordingly, many institutions with legal authority to invest in comparably
rated securities based on first mortgage loans may not be legally authorized to
invest in the Certificates, which because they evidence interests in a pool that
includes junior mortgage loans are not "mortgage related securities" under
SMMEA. See "LEGAL INVESTMENT" in the Prospectus.

                                  UNDERWRITING

      Subject to the terms and conditions set forth in the underwriting
agreement, dated _____ 199_ (the "Underwriting Agreement"), among the Depositor
and _______________________ (the "Underwriters"), the Depositor has agreed to
sell to the Underwriters, and the Underwriters have agreed to purchase from the
Depositor all the Certificates.

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

      The Depositor has been advised by the Underwriters that it proposes
initially to offer the Certificates to the public in Europe and the United
States at the offering price set forth herein and to certain dealers at such
price less a discount not in excess of     % of the Certificate denominations.
The Underwriters may allow and such dealers may reallow a discount not in excess
of      % of the Certificate denominations to certain other dealers. After the
initial public offering, the public offering price, such concessions and such
discounts may be changed.

      The Underwriting Agreement provides that the Depositor will indemnify the
Underwriters against certain civil liabilities, including liabilities under the
Act.

                                  LEGAL MATTERS

      Certain legal matters with respect to the Certificates will be passed upon
for _______________________________, for the Depositor by ______________________
and for the Underwriters by _________________.

                                     RATINGS

      It is a condition to issuance that the Certificates be rated "____" by
Standard & Poor's and "____" by Moody's.


                                      S-69
<PAGE>   71

      A securities rating addresses the likelihood of the receipt by
Certificateholders of distributions on the Mortgage Loans. The rating takes into
consideration the characteristics of the Mortgage Loans and the structural,
legal and tax aspects associated with the Certificates. The ratings on the
Certificates do not, however, constitute statements regarding the likelihood or
frequency of prepayments on the Mortgage Loans or the possibility that
Certificateholders might realize a lower than anticipated yield.

      [The ratings assigned to the Certificates will depend primarily upon the
creditworthiness of the Certificate Insurer. Any reduction in a rating assigned
to the claims-paying ability of the Certificate Insurer below the ratings
initially assigned to the Certificates may result in a reduction of one or more
of the ratings assigned to the Certificates.]

      A securities rating is not a recommendation to buy, sell or hold
securities and may be subject to revision or withdrawal at any time by the
assigning rating organization. Each securities rating should be evaluated
independently of similar ratings on different securities.

                          GLOBAL CLEARANCE, SETTLEMENT
                        AND TAX DOCUMENTATION PROCEDURES

      Except in certain limited circumstances, the globally offered Revolving
Home Equity Loan Asset-Backed Certificates, Series 199_-_ (the "Global
Securities") will be available only in book-entry form. Investors in the Global
Securities may hold such Global Securities through any of The Depository Trust
Company ("DTC"), Cedel or Euroclear. The Global Securities will be tradeable as
home market instruments in both the European and U.S. domestic markets. Initial
settlement and all secondary trades will settle in same-day funds.

      Secondary market trading between investors holding Global Securities
through Cedel and Euroclear will be conducted in the ordinary way in accordance
with their normal rules and operating procedures and in accordance with
conventional eurobond practice (i.e., seven calendar day settlement).

      Secondary market trading between investors holding Global Securities
through DTC will be conducted according to the rules and procedures applicable
to U.S. corporate debt obligations and prior Home Equity Loan Asset-Backed
Certificates issues.

      Secondary cross-market trading between Cedel or Euroclear and DTC
Participants holding Certificates will be effected on a delivery-against-payment
basis through the respective Depositaries of Cedel and Euroclear (in such
capacity) and as DTC Participants.

      Non-U.S. holders (as described below) of Global Securities will be subject
to U.S. withholding taxes unless such holders meet certain requirements and
deliver appropriate U.S. tax documents to the securities clearing organizations
or their participants.

Initial Settlement

      All Global Securities will be held in book-entry form by DTC in the name
of Cede & Co. as nominee of DTC. Investors' interests in the Global Securities
will be represented through financial institutions acting on their behalf as
direct and indirect Participants in DTC. As a result, Cedel and Euroclear will
hold positions on behalf of their participants through their respective
Depositaries, which in turn will hold such positions in accounts as DTC
Participants.

      Investors electing to hold their Global Securities through DTC will follow
the settlement practices applicable to prior Home Equity Loan Asset-Backed
Certificates issues. Investor securities custody accounts will be credited with
their holdings against payment in same-day funds on the settlement date.

      Investors electing to hold their Global Securities through Cedel or
Euroclear accounts will follow the settlement procedures applicable to
conventional eurobonds, except that there will be no temporary global security
and no "lock-up" or restricted period. Global Securities will


                                      I-1
<PAGE>   73

be credited to the securities custody accounts on the settlement date against
payment in same-day funds.

Secondary Market Trading

      Since the purchaser determines the place of delivery, it is important to
establish at the time of the trade where both the purchaser's and seller's
accounts are located to ensure that settlement can be made on the desired value
date.

      Trading between DTC Participants. Secondary market trading between DTC
Participants will be settled using the procedures applicable to prior Home
Equity Loan Asset-Backed Certificates issues in same-day funds.

      Trading between Cedel and/or Euroclear Participants. Secondary market
trading between Cedel Participants or Euroclear Participants will be settled
using the procedures applicable to conventional eurobonds in same-day funds.

      Trading between DTC seller and Cedel or Euroclear purchaser. When Global
Securities are to be transferred from the account of a DTC Participant to the
account of a Cedel Participant or a Euroclear Participant, the purchaser will
send instructions to Cedel or Euroclear through a Cedel Participant or Euroclear
Participant at least one business day prior to settlement. Cedel or Euroclear
will instruct the respective Depositary, as the case may be, to receive the
Global Securities against payment. Payment will include interest accrued on the
Global Securities from and including the last coupon payment date to and
excluding the settlement date, on the basis of the actual number of days in such
accrual period and a year assumed to consist of 360 days. For transactions
settling on the 31st of the month, payment will include interest accrued to and
excluding the first day of the following month. Payment will then be made by the
respective Depositary of the DTC Participant's account against delivery of the
Global Securities. After settlement has been completed, the Global Securities
will be credited to the respective clearing system and by the clearing system,
in accordance with its usual procedures, to the Cedel Participant's or Euroclear
Participant's account. The securities credit will appear the next day (European
time) and the cash debt will be back-valued to, and the interest on the Global
Securities will accrue from, the value date (which would be the preceding day
when settlement occurred in New York). If settlement is not completed on the
intended value date (i.e., the trade fails), the Cedel or Euroclear cash debt
will be valued instead as of the actual settlement date.

      Cedel Participants and Euroclear Participants will need to make available
to the respective clearing systems the funds necessary to process same-day funds
settlement. The most direct means of doing so is to preposition funds for
settlement, either from cash on hand or existing lines of credit, as they would
for any settlement occurring within Cedel or Euroclear. Under this approach,
they may take on credit exposure to Cedel or Euroclear until the Global
Securities are credited to their accounts one day later.

      As an alternative, if Cedel or Euroclear has extended a line of credit to
them, Cedel Participants or Euroclear Participants can elect not to preposition
funds and allow that credit line to be drawn upon the finance settlement. Under
this procedure, Cedel Participants or Euroclear Participants purchasing Global
Securities would incur overdraft charges for one day, assuming


                                      S-2
<PAGE>   74

they cleared the overdraft when the Global Securities were credited to their
accounts. However, interest on the Global Securities would accrue from the value
date. Therefore, in many cases the investment income on the Global Securities
earned during that one-day period may substantially reduce or offset the amount
of such overdraft charges, although this result will depend on each Cedel
Participant's or Euroclear Participant's particular cost of funds.

      Since the settlement is taking place during New York business hours, DTC
Participants can employ their usual procedures for sending Global Securities to
the respective European Depositary for the benefit of Cedel Participants or
Euroclear Participants. The sale proceeds will be available to the DTC seller on
the settlement date. Thus, to the DTC Participants a cross-market transaction
will settle no differently than a trade between two DTC Participants.

      Trading between Cedel or Euroclear Seller and DTC Purchaser. Due to time
zone differences in their favor, Cedel Participants and Euroclear Participants
may employ their customary procedures for transactions in which Global
Securities are to be transferred by the respective clearing system, through the
respective Depositary, to a DTC Participant. The seller will send instructions
to Cedel or Euroclear through a Cedel Participant or Euroclear Participant at
least one business day prior to settlement. In these cases Cedel or Euroclear
will instruct the respective Depositary, as appropriate, to deliver the Global
Securities to the DTC Participant's account against payment. Payment will
include interest accrued on the Global Securities from and including the last
coupon payment to and excluding the settlement date on the basis of the actual
number of days in such accrual period and a year assumed to consist of 360 days.
For transactions settling on the 31st of the month, payment will include
interest accrued to and excluding the first day of the following month. The
payment will then be reflected in the account of the Cedel Participant or
Euroclear Participant the following day, and receipt of the cash proceeds in the
Cedel Participant's or Euroclear Participant's account would be back-valued to
the value date (which would be the preceding day, when settlement occurred in
New York). Should the Cedel Participant or Euroclear Participant have a line of
credit with its respective clearing system and elect to be in debt in
anticipation of receipt of the sale proceeds in its account, the back-valuation
will extinguish any overdraft incurred over that one-day period. If settlement
is not completed on the intended value date (i.e., the trade fails), receipt of
the cash proceeds in the Cedel Participant's or Euroclear Participant's account
would instead be valued as of the actual settlement date.

      Finally, day traders that use Cedel or Euroclear and that purchase Global
Securities from DTC Participants for delivery to Cedel Participants or Euroclear
Participants should note that these trades would automatically fail on the sale
side unless affirmative action were taken. At least three techniques should be
readily available to eliminate this potential problem:

      (a) borrowing through Cedel or Euroclear for one day (until the purchase
side of the day trade is reflected in their Cedel or Euroclear accounts) in
accordance with the clearing system's customary procedures;

      (b) borrowing the Global Securities in the U.S. from a DTC Participant no
later than one day prior to settlement, which would give the Global Securities
sufficient time to be reflected in their Cedel or Euroclear account in order to
settle the sale side of the trade; or


                                      S-3
<PAGE>   75

      (c) staggering the value dates for the buy and sell sides of the trade so
that the value date for the purchase from the DTC Participant is at least one
day prior to the value date for the sale to the Cedel Participant or Euroclear
Participant.

Certain U.S. Federal Income Tax Documentation Requirements

      A beneficial owner of Global Securities holding securities through Cedel
or Euroclear (or through DTC if the holder has an address outside the U.S.) will
be subject to the 30% U.S. withholding tax that generally applies to payments of
interest (including original issue discount) on registered debt issued by U.S.
Persons, unless (i) each clearing system, bank or other financial institution
that holds customers' securities in the ordinary course of its trade or business
in the chain of intermediaries between such beneficial owner and the U.S. entity
required to withhold tax complies with applicable certification requirements and
(ii) such beneficial owner takes one of the following steps to obtain an
exemption or reduced tax rate:

      Exemption for non-U.S. Persons (Form W-8). Beneficial owners of Global
Securities that are non-U.S. Persons can obtain a complete exemption from the
withholding tax by filing a signed Form W-8 (Certificate of Foreign Status). If
the information shown on Form W-8 changes, a new Form W-8 must be filed within
30 days of such change.

      Exemption for non-U.S. Persons with effectively connected income (Form
4224). A non-U.S. Person, including a non-U.S. corporation or bank with a U.S.
branch, for which the interest income is effectively connected with its conduct
of a trade or business in the United States, can obtain an exemption from the
withholding tax by filing Form 4224 (Exemption from Withholding of Tax on Income
Effectively Connected with the Conduct of a Trade or Business in the United
States).

      Exemption or reduced rate for non-U.S. Persons resident in treaty
countries (Form 1001). Non-U.S. Persons that are Certificate Owners residing in
a country that has a tax treaty with the United States can obtain an exemption
or reduced tax rate (depending on the treaty terms) by filing Form 1001
(Ownership, Exemption or Reduced Rate Certificate). If the treaty provides only
for a reduced rate, withholding tax will be imposed at that rate unless the
filer alternatively files Form W-8. Form 1001 may be filed by the Certificate
Owners or his agent.

      Exemption for U.S. Persons (Form W-9). U.S. Persons can obtain a complete
exemption from the withholding tax by filing Form W-9 (Payer's Request for
Taxpayer Identification Number and Certification).

      U.S. Federal Income Tax Reporting Procedure. The Certificate Owner of a
Global Security or, in the case of a Form 1001 or a Form 4224 filer, his agent,
files by submitting the appropriate form to the person through whom it holds
(the clearing agency, in the case of persons holding directly on the books of
the clearing agency). Form W-8 and Form 1001 are effective for three calendar
years and Form 4224 is effective for one calendar year.

      The term "U.S. Person" means (i) a citizen or resident of the United
States, (ii) a corporation or partnership organized in or under the laws of the
United States or any political subdivision thereof or (iii) an estate or trust
the income of which is includible in gross income for


                                      S-4
<PAGE>   76

United States tax purposes, regardless of its source. This summary does not deal
with all aspects of U.S. Federal income tax withholding that may be relevant to
foreign holders of the Global Securities. Investors are advised to consult their
own tax advisors for specific tax advice concerning their holding and disposing
of the Global Securities.

                           Asset-Backed Certificates
                               Asset-Backed Notes
                              (Issuable in Series)

      Banc One ABS Corporation (the "Depositor") may offer from time to time
under this Prospectus and related Prospectus Supplements the Asset-Backed Notes
(the "Notes") and the Asset-Backed Certificates (the "Certificates" and,
together with the Notes, the "Securities") which may be sold from time to time
in one or more series (each, a "Series"). A Series of Securities may consist of
Notes, Certificates or both.

      As specified in the related Prospectus Supplement, the Certificates of a
Series will evidence undivided interests in certain assets deposited into a
trust (each, a "Trust Fund") by the Depositor pursuant to a Pooling and
Servicing Agreement or a Trust Agreement, as described herein. As specified in
the related Prospectus Supplement, the Notes of a Series will be issued and
secured pursuant to an Indenture and will represent indebtedness of the related
Trust Fund. The Trust Fund for a Series of Securities will include assets
purchased from one or more bank or non-bank direct or indirect subsidiaries of
BANC ONE CORPORATION ("BANC ONE") specified in the related Prospectus Supplement
(each, a "Seller" and collectively, the "Sellers") composed of one or more pools
of revolving home equity loans and lines of credit (collectively, the "Mortgage
Loans"), secured by mortgages primarily on one- to four-family residential
properties, (b) all monies due thereunder net, if and as provided in the related
Prospectus Supplement, of certain amounts payable to Bank One, N.A., as servicer
of the Mortgage Loans or other servicer specified in the related Prospectus
Supplement (the "Servicer"), and (c) certain funds, Credit Enhancement (as
defined herein) and other assets as described herein and in the related
Prospectus Supplement.

      Each Series of Securities will be issued in one or more classes (each, a
"Class"). Interest on and principal of the Securities of a Series will be
payable on each Distribution Date specified in the related Prospectus
Supplement, at the times, at the rates, in the amounts and in the order of
priority set forth in the related Prospectus Supplement.

      If a Series includes multiple Classes, such Classes may vary with respect
to the amount, percentage and timing of distributions of principal, interest or
both and one or more Classes may be subordinated to other Classes with respect
to distributions of principal, interest or both as described herein and in the
related Prospectus Supplement. If so specified in the related Prospectus
Supplement, the Mortgage Loans and other assets comprising the Trust Fund may be
divided into one or more Asset Groups and each Class of the related Series will
evidence beneficial ownership of the corresponding Asset Group, as applicable.

      The rate of reduction of the aggregate principal balance of each Class of
a Series may depend principally upon the rate of payment (including prepayments)
with respect to the Mortgage Loans. A rate of prepayment lower or higher than
anticipated will affect the yield on the Securities of a Series in the manner
described herein and in the related Prospectus Supplement. Under certain limited
circumstances described herein and in the related Prospectus Supplement, a
Series of Securities may be subject to termination or redemption under the
circumstances described herein and in the related Prospectus Supplement.

         FOR A DISCUSSION OF CERTAIN RISKS ASSOCIATED WITH AN INVESTMENT
                IN THE SECURITIES, SEE "RISK FACTORS" ON PAGE 9.

Principal Payments........... All payments of principal of a Series of 
                               Securities will be made in an aggregate amount
                               determined as set forth in the related Prospectus
                               Supplement and will be paid at the times and will
                               be allocated among the Classes of such Series in
                               the order and amounts, and will be applied either
                               on a pro rata or a random lot basis among all
                               Securities of any such Class, all as specified in
                               the related Prospectus Supplement. A Series of
                               Securities may provide for a period during which
                               no or only specified payments of principal are
                               made except upon the occurrence of certain
                               conditions, all as specified in the related
                               Prospectus Supplement.

Final Scheduled
  Distribution Date
  of the Securities.......... The Final Scheduled Distribution Date with respect
                               to each Class of Notes is the date on or before
                               which principal thereof will be fully paid and,
                               with respect to each Class of Certificates, is
                               the date after which no Certificates of such
                               Class are expected to remain outstanding, in each
                               case calculated on the basis of the assumptions
                               applicable to such Series described in the
                               related Prospectus Supplement. The Final
                               Scheduled Distribution Date of a Class may equal
                               the maturity date of the Mortgage Loan in the
                               related Trust Fund which has the latest stated
                               maturity or will be determined as described
                               herein and in the related Prospectus Supplement.

                              The actual final Distribution Date of the
                               Securities of a Series will depend primarily upon
                               the rate of payment (including prepayments,
                               liquidations due to default, the receipt of
                               proceeds from casualty insurance policies and
                               repurchases) of the Mortgage Loans in the related
                               Trust Fund. Unless otherwise specified in the
                               related Prospectus Supplement, the actual final
                               Distribution Date of any Security is likely to
                               occur earlier and may occur substantially earlier
                               or may occur later than its Final Scheduled
                               Distribution Date as a result of the application
                               of prepayments to the reduction of the principal
                               balances of the Securities and as a result of
                               defaults on the Mortgage Loans. The rate of
                               payments on the Mortgage Loans in the Trust Fund
                               for a Series will depend on a variety of factors,
                               including certain characteristics of such
                               Mortgage Loans and the prevailing level of
                               interest rates from time to time, as well as on a
                               variety of economic, demographic, tax, legal,
                               social and other factors. No assurance can be
                               given as to the actual prepayment experience with
                               respect to a Series. See "RISK FACTORS-Prepayment
                               and Yield Considerations" and "DESCRIPTION OF THE
                               SECURITIES - Weighted Average Life of the
                               Securities" herein.

Optional Termination......... One or more Classes of Securities of any Series 
                               may be redeemed or repurchased in whole or in
                               part, at the Depositor's or the Servicer's
                               option, at such time and under the circumstances
                               specified in the related Prospectus Supplement,
                               at the price set forth therein. If so specified
                               in the related Prospectus Supplement for a Series
                               of Securities, the Depositor, the Servicer, or
                               such other entity that is specified in the
                               related Prospectus Supplement, may, at its
                               option, cause an early termination of the related
                               Trust Fund by repurchasing all of the Mortgage
                               Loans remaining in the Trust Fund on or after a
                               specified date, or on or after such time as the
                               aggregate principal balance of the Securities of
                               the Series or the Mortgage Loans relating to such
                               Series, as specified in the related Prospectus
                               Supplement, is less than the amount or percentage
                               specified in the related Prospectus Supplement.
                               See "DESCRIPTION OF THE SECURITIES-Optional
                               Purchase or Termination."

                              In addition, the Prospectus Supplement may provide
                               other circumstances under which Holders of
                               Securities of a Series could be fully paid
                               significantly earlier than would otherwise be the
                               case if payments or distributions were solely
                               based on the activity of the related Mortgage
                               Loans.

The Transferor Interest...... If so specified in the related Prospectus 
                               Supplement, interests in a Trust Fund not
                               represented by the related Series of Securities
                               may be represented by a Transferor Interest,
                               which initially will be retained by the related
                               Seller or an affiliate thereof and which will not
                               be offered hereby. If so specified in the related
                               Prospectus Supplement, the principal amount of
                               the Transferor Interest will fluctuate as draws
                               are made with respect to the Mortgage Loans and
                               as Principal Collections are received. The
                               related Prospectus Supplement may specify a
                               minimum interest (the "Minimum Transferor
                               Interest") required to be maintained with respect
                               to a Trust Fund; provided that unless otherwise
                               specified in the related Prospectus Supplement,
                               the Minimum Transferor Interest may be reduced or
                               eliminated without the consent of the Holders of
                               the Securities of the applicable Series.

The Trust Fund............... The Trust Fund for a Series of Securities will 
                               consist of one or more of the assets described
                               below, as described in the related Prospectus
                               Supplement.

   A. Mortgage Loans......... The Mortgage Loans for a Series will consist of 
                               revolving home equity loans and lines of credit
                               originated or purchased by the Seller or Sellers
                               specified in the related Prospectus Supplement,
                               each of which is an affiliate of the Depositor,
                               and sold each such Seller to the Depositor.

                              Mortgage Loans may, as specified in the related
                               Prospectus Supplement, have various payment
                               characteristics, including balloon or other
                               irregular payment features, and may accrue
                               interest at a fixed rate or an adjustable rate.
                               To the extent provided in the related Prospectus
                               Supplement, additional Mortgage Loans may be
                               periodically added to the Trust Fund, or may be
                               removed from time to time if certain conditions
                               are met, as described in the related Prospectus
                               Supplement. If so specified in the related
                               Prospectus Supplement, during the term of a Trust
                               Fund, all Additional Balances will be transferred
                               to and become Mortgaged Property of the Trust
                               Fund. As a result, the Pool Balance of a Trust
                               Fund may fluctuate from day to day because the
                               amount of Additional Balances and the amount of
                               principal payments with respect to the Mortgage
                               Loans will usually differ from day to day.

                              The Mortgage Loans will be secured by mortgages
                               or deeds of trust or other similar security
                               instruments creating a lien on a Mortgaged
                               Property, which may be subordinated to one or
                               more senior liens on the Mortgaged Property, as
                               described in the related Prospectus Supplement.

                              The related Prospectus Supplement will describe

                               required with respect to a Series, will generally
                               be made only if the Servicer determines such
                               Advances to be recoverable. Unless otherwise
                               specified in the related Prospectus Supplement,
                               will be reimbursable to the Servicer from
                               scheduled payments of principal and interest,
                               late collections, or from the proceeds of
                               liquidation of the related Mortgage Loans or from
                               other recoveries relating to such Mortgage Loans

                               from other credit support). Under certain limited
                               circumstances, the Servicer may resign or be
                               removed, in which event either the Trustee or a
                               third-party servicer will be appointed as
                               successor servicer. The Servicer will receive a
                               periodic fee as servicing compensation (the
                               "Servicing Fee") and may, as specified herein and
                               in the related Prospectus Supplement, receive
                               certain additional compensation. See "SERVICING
                               OF LOANS--Servicing Compensation and Payment of
                               Expenses".

Federal Income
  Tax Considerations
   A. Debt Securities........ If so described in the related Prospectus 
                               Supplement, a Series of Securities will include
                               one or more Classes of taxable debt obligations
                               under the Internal Revenue Code of 1986, as
                               amended (the "Code"). Stated interest with
                               respect to such Classes of Securities will be
                               reported by a Holder in accordance with the
                               Holder's method of accounting. Certain Classes of
                               Securities may, if specified in the related
                               Prospectus Supplement, be issued with original
                               issue discount that is not de minimis. In such
                               cases, the Holder will be required to include
                               original issue discount in gross income as it
                               accrues, which may be prior to the receipt of
                               cash attributable to such income. If a Security
                               is issued at a premium, the Holder may be
                               entitled to make an election to amortize such
                               premium on a constant yield method. See "CERTAIN
                               FEDERAL INCOME TAX CONSIDERATIONS."

   B. Grantor Trust.......... If so specified in the Prospectus Supplement, the
                               Trust Fund will be treated as a grantor trust for
                               federal income tax purposes. A Certificateholder,
                               by its acceptance of a Certificate, will agree to
                               treat the related Trust as a grantor trust in
                               which such Certificateholder is a grantor for
                               federal income tax purposes.

   C. Owner Trust
      Securities............. If so specified in the Prospectus Supplement, the 
                               Trust Fund will be treated as a partnership for
                               purposes of federal income tax. Each Noteholder,
                               by the acceptance of a Note of a given series,
                               will agree to treat such Note as indebtedness,
                               and each Certificateholder, by the acceptance of
                               a Certificate of a given series, will agree to
                               treat the related Trust as a partnership in which
                               such Certificateholder is a partner for federal
                               income tax purposes. In the event the Trust Fund
                               will be treated as a partnership, the
                               Certificates may not be transferred to non-U.S.
                               holders, and any such transfer shall be void.
                               Alternative characterizations of such Trust and
                               such Certificates are possible. See "CERTAIN
                               FEDERAL INCOME TAX CONSIDERATIONS."

ERISA Considerations......... A fiduciary of any employee benefit or other plan 
                               subject to the Employee Retirement Income
                               Security Act of 1974, as amended ("ERISA"), or
                               Section 4975 of the Code should carefully review
                               with its own legal advisors whether the purchase
                               or holding of Securities could give rise to a
                               transaction prohibited or otherwise impermissible
                               under ERISA or the Code. See "ERISA
                               CONSIDERATIONS."

Legal Investment............. Unless otherwise specified in the related 
                               Prospectus Supplement, Securities of each Series
                               offered by this Prospectus and the related
                               Prospectus Supplement will not constitute

                               Act of 1984 ("SMMEA"). Investors whose investment
                               authority is subject to legal restrictions should
                               consult their own legal advisors to determine
                               whether and to what extent the Securities
                               constitute legal investments for them. See "LEGAL
                               INVESTMENT."

Use of Proceeds.............. The Depositor will use the net proceeds from the 
                               sale of each Series for one or more of the
                               following purposes: (i) to purchase the related
                               Mortgage Loans, (ii) to repay indebtedness which

                               Funds described in the related Prospectus
                               Supplement and (iv) to pay costs of structuring
                               and issuing such Securities, including the costs
                               of obtaining Credit Enhancement, if any. If so
                               specified in the related Prospectus Supplement,
                               the purchase of the Mortgage Loans for a Series
                               may be effected by an exchange of Securities with
                               the Seller of such Mortgage Loans. See "USE OF
                               PROCEEDS."

Ratings...................... It will be a requirement for issuance of any 
                               Series that the Securities offered by this
                               Prospectus and the related Prospectus Supplement

                               its four highest applicable rating categories.
                               The rating or ratings applicable to Securities of
                               each Series offered hereby and by the related
                               Prospectus Supplement will be as set forth in the
                               related Prospectus Supplement. A securities
                               rating should be evaluated independently of
                               similar ratings on different types of securities.
                               A securities rating does not address the effect
                               that the rate of prepayments on Mortgage Loans
                               for a Series may have on the yield to investors
                               in the Securities of such Series. See "RISK
                               FACTORS-Rating of Securities."

                                  RISK FACTORS

      Investors should consider, among other things, the following factors in
connection with the purchase of the Securities. 

Securities

      Limited Liquidity. There will be no market for the Securities of any
Series prior to the issuance thereof, and there can be no assurance that a
secondary market will develop or, if it does develop, that it will provide
Holders with liquidity of investment or will continue for the life of the
Securities of such Series. If so specified in the related Prospectus Supplement,
the underwriters for a Series specified in the related Prospectus Supplement,
may make a secondary market in the Securities, but have no obligation to do so.
None of the Securities will be listed on any securities exchange. Issuance of
any of the Securities in book-entry form may reduce the liquidity of such
Securities in the secondary trading market because investors may be unwilling to
purchase Securities for which they cannot obtain physical certificates. In
addition, because transactions in Securities of a Series in book-entry form may
be effected only through a depositary and its direct and indirect participants,
the ability of a Holder to pledge Securities to persons or entities that do not
participate in the depositary system may be limited.

      Limited Obligations. The Securities of a Series will not represent an
interest in or an obligation of the Depositor, BANC ONE, any Seller, the
Servicer or any of their affiliates and will be payable solely from the assets
of the Trust Fund for such Securities. There will be no recourse to the
Depositor or any other person for any default on the Notes or any failure to
receive distributions on the Certificates. Consequently, Holders of Securities
of each Series must rely solely upon payments with respect to the Mortgage Loans
and the other assets constituting the Trust Fund for a Series of Securities,
including, if applicable, any amounts available pursuant to any Credit
Enhancement for such Series, for the payment of principal of and interest on the
Securities of such Series. The Depositor does not have, nor is it expected to
have, any significant assets.

      Holders of Notes will be required under the Indenture to proceed only
against the Mortgage Loans and other assets constituting the related Trust Fund
in the case of a default with respect to such Notes and may not proceed against
any assets of the Depositor. If payments with respect to the Mortgage Loans and
such other assets securing a Series of Notes, including any Credit Enhancement,
were to become insufficient to make payments on such Notes, no other assets
would be available for payment of the deficiency.

      The only obligations, if any, of the Depositor with respect to the
Securities of any Series will be to purchase, or substitute substantially
similar mortgage loans for, or cause the related Seller to purchase or
substitute, any Mortgage Loans as to which there is defective documentation or a
breach of certain representations and warranties. See "THE AGREEMENTS-Assignment
of Mortgage Loans". The Depositor does not have, and is not expected in the
future to have, any significant assets with which to meet any obligation to
repurchase Mortgage Loans with respect to which there has been a breach of any
representation or warranty.

      Credit Enhancement. Although Credit Enhancement, if any, with respect to a
Series of Securities is intended to reduce the risk of delinquent payments or
losses to Holders of the Class or Classes of Securities entitled to the benefit
thereof, the amount of such Credit Enhancement will be limited, as set forth in
the related Prospectus Supplement, and will decline and could be depleted under
certain circumstances prior to the payment in full of the related Series of
Securities, and as a result Holders may suffer losses. See "CREDIT ENHANCEMENT."

      Prepayment and Yield Considerations. The yield to maturity experienced by
a Holder of Securities may be affected by the rate of payment of principal of
the Mortgage Loans. The timing of principal payments of the Securities of a
Series will be affected by a number of factors, including the following: (i) the
extent of prepayments of the Mortgage Loans, which prepayments may be influenced
by a variety of factors, (ii) the manner of allocating principal payments among
the Classes of Securities of a Series as specified in the related Prospectus
Supplement and (iii) the exercise by the party entitled thereto of any right of
optional termination. See "DESCRIPTION OF THE SECURITIES- Weighted Average Life
of Securities; Prepayment and Yield Considerations." Prepayments may also result
from repurchases of loans due to material breaches of the Seller's or the
Depositor's warranties. The effective yield to Holders will also be affected by
the timing of interest accrual and payments and other factors specific to the
Mortgage Loans underlying a Series or the structural characteristics of the
Securities of a Series, all as more particularly described in the related
Prospectus Supplement.

      The Depositor is not aware of any publicly available studies or statistics
on the rate of prepayment of mortgage loans such as the Mortgage Loans.
Generally, home equity loans and lines of credit are not viewed by 


                                       9
<PAGE>   88

mortgagors as permanent financing. Accordingly, the Mortgage Loans may
experience higher rates of prepayment than traditional mortgage loans. On the
other hand, it may be expected that a portion of the borrowers will not prepay
their Mortgage Loans to any significant degree.

      Rating of the Securities. It will be a condition to the issuance of a
Series of Securities that they be rated in one of the four highest rating
categories by one or more Rating Agencies identified in the related Prospectus
Supplement. Any such rating would be based on, among other things, the adequacy
of the value of the Mortgage Loans and any Credit Enhancement with respect to
such Series. Such rating should not be deemed a recommendation to purchase, hold
or sell Securities, inasmuch as it does not address market price or suitability
for a particular investor. There is also no assurance that any such rating will
remain in effect for any given period of time or may not be lowered or withdrawn
entirely by the applicable Rating Agency if in its judgment circumstances in the
future so warrant. In addition to being lowered or withdrawn due to any erosion
in the adequacy of the value of the Mortgage Loans, such rating might also be
lowered or withdrawn, among other reasons, because of an adverse change in the
financial or other condition of an Enhancer or a change in the rating of such
Enhancer's long term debt. 

Risks of the Mortgage Loans

      Nature of Mortgage Loans and Mortgaged Properties. The Mortgage Loans are
expected to be secured by Mortgages which consist primarily of junior liens
subordinate to the rights of the mortgagee under the related senior mortgage or
mortgages. As a result, the proceeds from any liquidation, insurance or
condemnation proceedings will be available to satisfy the outstanding balance of
such Mortgage only to the extent that the claims of such senior mortgagees have
been satisfied in full, including any related foreclosure costs. In addition, a
junior mortgagee may not foreclose on the Mortgaged Property securing a junior
mortgage unless it forecloses subject to the senior mortgages, in which case it
must either pay the entire amount due on the senior mortgages to the senior
mortgagees at or prior to the foreclosure sale or undertake the obligation to
make payments on the senior mortgages in the event the mortgagor is in default
thereunder. The Trust Fund will not have any source of funds to satisfy the
senior mortgages or make payments due to the senior mortgagees.

      There are several factors that could adversely affect the value of
Mortgaged Properties such that the outstanding balance of the related Mortgage
Loan, together with any senior financing on the Mortgaged Properties, would
equal or exceed the value of the Mortgaged Properties. Among such factors are an
overall decline in the residential real estate market in the areas in which the
Mortgaged Properties are located or a decline in the general condition of the
Mortgaged Properties as a result of failure of borrowers to maintain adequately
the Mortgaged Properties or of natural disasters that are not necessarily
covered by insurance, such as earthquakes and floods. Any such decline could
extinguish the value of a junior interest in a Mortgaged Property before having
any effect on the related senior interest therein. If such a decline occurs, the
actual rates of delinquencies, foreclosure and losses on the junior Mortgage
Loans could be higher than those currently experienced in the mortgage lending
industry in general.

      Minimum monthly payments on the Mortgage Loans may be limited to accrued
interest. Although borrowers under certain of the Mortgage Loans may choose to
pay down all or a part of their outstanding principal balance prior to maturity,
such borrowers are under no obligation to do so and, if such balances have not
been substantially paid down prior to maturity, some borrowers may be unable to
pay the required final payment.

      Environmental Risks. Real Mortgaged Property pledged as security to a
lender may be subject to certain environmental risks. Under the laws of certain
states, contamination of a Mortgaged Property may give rise to a lien on the
Mortgaged Property to assure the costs of clean-up. In several states, such a
lien has priority over the lien of an existing mortgage or owner's interest
against such Mortgaged Property. In addition, under the laws of some states and
under the federal Comprehensive Environmental Response, Compensation, and
Liability Act of 1980 ("CERCLA"), a lender may be liable, as an "owner" or
"operator," for costs of addressing releases or threatened releases of hazardous
substances that require remedy at a Mortgaged Property, if agents or employees
of the lender have become sufficiently involved in the operations of the
borrower, regardless of whether or not the environmental damage or threat was
caused by a prior owner. A lender also risks such liability on foreclosure of
the Mortgaged Property.

      Certain Other Legal Considerations Regarding the Mortgage Loans.
Applicable state laws generally regulate interest rates and other charges and
require certain disclosures. In addition, other state laws, public policy and
general principles of equity relating to the protection of consumers, unfair and
deceptive practices and debt 


                                       10
<PAGE>   89

collection practices may apply to the origination, servicing and collection of
the Mortgage Loans. Depending on the provisions of the applicable law and the
specific facts and circumstances involved, violations of these laws, policies
and principles may limit the ability of the Servicer to collect all or part of
the principal of or interest on the Mortgage Loans, may entitle the borrower to
a refund of amounts previously paid and, in addition, could subject the owner of
the Mortgage Loan to damages and administrative enforcement.

      The Mortgage Loans are also subject to Federal laws, including:

            (i) the Federal Truth in Lending Act and Regulation Z promulgated
      thereunder, which require certain disclosures to the borrowers regarding
      the terms of the Mortgage Loans;

            (ii) the Equal Credit Opportunity Act and Regulation B promulgated
      thereunder, which prohibit discrimination on the basis of age, race,
      color, sex, religion, marital status, national origin, receipt of public
      assistance or the exercise of any right under the Consumer Credit
      Protection Act, in the extension of credit; and

            (iii) the Americans with Disabilities Act, which, among other
      things, prohibits discrimination on the basis of disability in the full
      and equal enjoyment of the goods, services, facilities, privileges,
      advantages or accommodations of any place of public accommodation;

            (iv) the Fair Credit Reporting Act, which regulates the use and
      reporting of information related to the borrower's credit experience.

      Violations of certain provisions of these Federal laws may limit the
ability of the Servicer to collect all or part of the principal of or interest
on the Mortgage Loans and in addition could subject the Trust Fund to damages
and administrative enforcement. The Mortgage Loans may be subject to the Home
Ownership and Equity Protection Act of 1994 (the "Act") which amended the Truth
in Lending Act as it applies to mortgages subject to the Act. The Act requires
certain additional disclosures, specifies the timing of such disclosures and
limits or prohibits inclusion of certain provisions in mortgages subject to the
Act. The Act also provides that any purchaser or assignee of a mortgage covered
by the Act is subject to all of the claims and defenses which the borrower could
assert against the original lender. The maximum damages that may be recovered
under the Act from an assignee is the remaining amount of indebtedness plus the
total amount paid by the borrower in connection with the Mortgage Loan. If the
Trust Fund includes Mortgage Loans subject to the Act, it will be subject to all
of the claims and defenses which the borrower could assert against the Seller.
Any violation of the Act which would result in such liability would be a breach
of the Seller's representations and warranties, and the Seller would be
obligated to cure, repurchase or, if permitted by the Agreement, substitute for
the Mortgage Loan in question. In addition, numerous other federal and state
statutory provisions, including the federal bankruptcy laws, the Soldiers' and
Sailors' civil Relief Act of 1940 and state debtor relief laws, also may
adversely affect the Servicer's ability to collect the principal of or interest
on the Mortgage Loans and also would affect the interests of the Holders in such
Mortgage Loans if such laws result in the Mortgage Loans being uncollectible.
See "CERTAIN LEGAL ASPECTS OF THE MORTGAGE LOANS".

      Transfer of Mortgage Loans. If so specified in the related Prospectus
Supplement, the Servicer may be entitled to maintain possession of the
documentation relating to each Mortgage Loan, including the Credit Line
Agreements and related documents or other evidence of indebtedness signed by the
borrower, and assignments of the related mortgage to the Trust Fund may not be
required to be recorded, in each case until the occurrence of the events
(generally related to the rating assigned to unsecured debt of the Servicer)
specified in the related Prospectus Supplement. Failure to deliver such
documents to the related Trustee (or a third-party custodian on behalf of the
Trustee) will have the result in most, if not all, states, and failure to record
the assignments of the related mortgages to the related Trustee will have the
result in certain states in which the Mortgaged Properties are located, of
making the sale of the Principal Balances as of the Cut-off Date, Additional
Balances and related documents potentially ineffective against certain creditors
of the related Seller or the purchaser of a Mortgage Loan who had no notice of
the prior conveyance to the Trust Fund if such purchaser perfects his interest
by taking possession of the evidence of indebtedness.

      Each Seller will be required to represent in the related Purchase
Agreement that the transfer by it of all of its right, title and interest in the
Mortgage Loans underlying a Series of Securities is either a valid transfer and
assignment of such Mortgage Loans or the grant to the Trust Fund of a security
interest in the Mortgage Loans. If the transfer of the related Mortgage Loans to
the Trust Fund is deemed to create a security interest under the applicable
Uniform Commercial Code ("UCC"), tax or other governmental liens on the
Mortgaged Property of the Seller arising before any Mortgage Loan comes into
existence may have priority over the Trust's interest in such 


                                       11
<PAGE>   90

Mortgage Loan. In addition, if the FDIC were appointed receiver of a Seller, the
receiver's administrative expenses might also have priority over the Trust
Fund's interest in the Mortgage Loans, but under the Federal Deposit Insurance
Act, to the extent such Seller grants a security interest in the related
Mortgage Loans to the Trust Fund, such security interest is perfected prior to
the insolvency of such Seller and such security interest was not taken in
contemplation of insolvency or with the intent to hinder, delay or defraud
creditors, such security interest should not be subject to avoidance by the
FDIC, as conservator or receiver. The insolvency of a Seller may also have other
potential consequences described in the related Prospectus Supplement,
including, for example, an early termination of the related Trust Fund.

      Geographic Concentration and Local Real Estate Markets. The Prospectus
Supplement related to a Series of Securities will contain information with
respect to the geographic concentration of Mortgaged Properties securing the
related Mortgage Loans. Any concentration of the Mortgage Loans relating to any
Series of Securities in a particular region may present risk considerations in
addition to those generally present for similar securities without such
concentration. Certain geographic regions of the United States from time to time
will experience weaker regional economic conditions and housing markets and
consequently will experience higher rates of loss and delinquency on mortgage
loans generally. Declines in values of the Mortgaged Properties in any region
may particularly affect the position of a junior mortgagee, and could extinguish
the interest of the holder of such junior lien.

      In many cases, home equity revolving credit line borrowers have primary
residences with above average values, and those properties may experience
greater relative declines in value than other properties with lower values. A
rise in interest rates over a period of time and the general condition of the
Mortgaged Property as well as other factors may have the effect of reducing the
value of the Mortgaged Property from the appraised value at the time the
Mortgage Loan was originated. Such reduction may reduce the likelihood of
liquidation or other proceeds being sufficient to satisfy the related Mortgage
Loan after satisfaction of any senior liens. In addition, if the borrower has an
adjustable rate first mortgage loan, any increase in the interest rate thereon
may adversely affect the borrower's ability to make payments on the related
Mortgage Loan.

      Servicer's Ability to Change the Terms of the Mortgage Loans. If and under
the terms specified in the related Prospectus Supplement, the Servicer may have
the ability to agree to changes in the terms of a Credit Line Agreement or other
document evidencing the Mortgage Loan indebtedness. No assurance can be given
that changes in applicable law or the market for home equity loans or prudent
business practice will not result in changes in the terms of the Mortgage Loans
after transfer to the related Trust Fund.

      Other Considerations. There is no assurance that the market value of the
Mortgage Loans or any other assets for a Series will at any time be equal to or
greater than the aggregate principal amount of the Securities of such Series
then outstanding, plus accrued interest thereon. Moreover, upon an event of
default under the Indenture for a Series of Notes and a sale of the assets in
the Trust Fund or upon a sale of the assets of a Trust Fund for a Series of
Certificates, the Trustee, the Servicer, any Enhancer and any other service
provider specified in the related Prospectus Supplement generally will be
entitled to receive the proceeds of any such sale to the extent of unpaid fees
and other amounts owing to such persons under the related Agreement prior to
distributions to holders of Securities. Upon any such sale, the proceeds thereof
may be insufficient to pay in full the principal of and interest on the
Securities of such Series.

      Liquidation expenses with respect to defaulted 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 loan having a small remaining principal balance as it would in the
case of a defaulted 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 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 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 first
mortgage loans.


                                       12
<PAGE>   91

      Further, foreclosure and similar actions are subject to delays and may
take several years to complete, resulting in delays in the receipt of proceeds
available for distribution to Holders of the related Securities. Such delays may
depend upon, among other things, the required procedures for foreclosure in the
jurisdiction in which the related Mortgaged Property is located, the
availability of defenses to such action, the timing of the foreclosure action
and other factors. See "CERTAIN LEGAL ASPECTS OF THE MORTGAGE LOANS--Foreclosure
on Mortgages".

                         DESCRIPTION OF THE SECURITIES

General

      Each Series of Notes will be issued pursuant to an indenture (the
"Indenture") between the related Trust Fund and the entity named in the related
Prospectus Supplement as trustee (the "Trustee") with respect to such Series. A
form of Indenture has been filed as an exhibit to the Registration Statement of
which this Prospectus forms a part. The Certificates will also be issued in
Series pursuant to separate agreements (each, a "Pooling and Servicing
Agreement" or a "Trust Agreement") among the Depositor, the Servicer and the
Trustee. A form of Pooling and Servicing Agreement has been filed as an exhibit
to the Registration Statement of which this Prospectus forms a part. A Series
may consist of Notes, Certificates or both.

      The applicable Seller or Sellers may agree to reimburse the Depositor for
certain fees and expenses of the Depositor incurred in connection with the
offering of the Securities.

      The following summaries describe certain provisions in the Agreements
common to each Series of Securities. The summaries do not purport to be complete
and are subject to, and are qualified in their entirety by reference to, the
provisions of the Agreements and the Prospectus Supplement relating to each
Series of Securities. Where particular provisions or terms used in the
Agreements are referred to, the actual provisions (including definitions of
terms) are incorporated herein by reference as part of such summaries.

      Each Series of Securities will consist of one or more Classes of
Securities, one or more of which may be Subordinate Securities. The Securities
of each Series will be issued only in fully registered form, without coupons, in
the authorized denominations for each Class specified in the related Prospectus
Supplement. Upon satisfaction of the conditions, if any, applicable to a Class
of a Series, as described in the related Prospectus Supplement, the transfer of
the Securities may be registered and the Securities may be exchanged at the
office of the Trustee specified in the Prospectus Supplement without the payment
of any service charge other than any tax or governmental charge payable in
connection with such registration of transfer or exchange. If specified in the
related Prospectus Supplement, one or more Classes of a Series may be available
in book-entry form only.

      Unless otherwise provided in the related Prospectus Supplement, payments
of principal of and interest on a Series of Securities will be made on the
Distribution Dates specified in the Prospectus Supplement relating to such
Series by check mailed to Holders of such Series, registered as such at the
close of business on the record date specified in the related Prospectus
Supplement applicable to such Distribution Dates at their addresses appearing on
the security register, except that (a) payments may be made by wire transfer (at
the expense of the Holder requesting payment by wire transfer) in certain
circumstances described in the related Prospectus Supplement and (b) final
payments of principal in retirement of each Security will be made only upon
presentation and surrender of such Security at the office of the Trustee
specified in the Prospectus Supplement. Notice of the final payment on a
Security will be mailed to the Holder of such Security before the Distribution
Date on which the final principal payment on any Security is expected to be made
to the Holder of such Security.

      Payments of principal of and interest on the Securities will be made by
the Trustee, or a paying agent on behalf of the Trustee, as specified in the
related Prospectus Supplement. Unless otherwise provided in the related
Prospectus Supplement, all payments with respect to the Mortgage Loans for a
Series, together with reinvestment income thereon, amounts withdrawn from any
Reserve Fund, and amounts available pursuant to any other Credit Enhancement
will be deposited directly into the Collection Account and, net, if and as
provided in the related Prospectus Supplement, of certain amounts payable to the
related Servicer and any other person specified in the Prospectus Supplement
will thereafter be deposited into the Distribution Account and will be available
to make payments on Securities of such Series on the next Distribution Date, as
the case may be. See "THE TRUST FUNDS-Collection and Distribution Accounts."

Valuation of the Mortgage Loans

      If specified in the related Prospectus Supplement for a Series of Notes,
each Mortgage Loan included in the related Trust Fund for a Series may be
assigned an initial "Asset Value." Unless otherwise specified in the related
Prospectus Supplement, at any time the Asset Value of the Mortgage Loans will be
equal to the product of the Asset Value Percentage as set forth in the Indenture
and the lesser of (a) the stream of remaining regularly scheduled payments on
the Mortgage Loans, net, unless otherwise provided in the related Prospectus
Supplement, of certain 


                                       14
<PAGE>   93

amounts payable as expenses, together with income earned on each such scheduled
payment received through the day preceding the next Distribution Date at the
Assumed Reinvestment Rate, if any, discounted to present value at the highest
interest rate on the Notes of such Series over periods equal to the interval
between payments on the Notes, and (b) the then principal balance of the
Mortgage Loans. Unless otherwise specified in the related Prospectus Supplement,
the initial Asset Value of the Mortgage Loans will be at least equal to the
principal amount of the Notes of the related Series at the date of issuance
thereof.

      The "Assumed Reinvestment Rate", if any, for a Series will be the highest
rate permitted by the Rating Agency or a rate insured by means of a surety bond,
guaranteed investment contract, Deposit Agreement or other arrangement
satisfactory to the Rating Agency. If the Assumed Reinvestment Rate is so
insured, the related Prospectus Supplement will set forth the terms of such
arrangement. 

The Transferor Interest

      If so specified in the related Prospectus Supplement, interests in a Trust
Fund not represented by the related Series of Certificates may be represented by
the Transferor Interest, which initially will be retained by the related Sellers
or one or more affiliates thereof and which will not be offered hereby. If so
specified in the related Prospectus Supplement, the principal amount of the
Transferor Interest will fluctuate as draws are made with respect to the
Mortgage Loans and as Principal Collections are received. The related Prospectus
Supplement may specify a minimum interest (the "Minimum Transferor Interest")
required to be maintained with respect to a Trust Fund.

      If so specified in the related Prospectus Supplement, the holder of the
Transferor Interest may have the right to remove Mortgage Loans from the related
Trust Fund, under the circumstances described therein. 

Allocations; Application of Collections

      The related Prospectus Supplement will describe the allocation or means of
allocation of collections on the Mortgage Loans available to pay interest on and
principal of a Series of Securities. In general, except as otherwise described
in the related Prospectus Supplement, collections will generally be allocated in
accordance with the related Credit Line Agreements or other Loan Documents
between amounts collected in respect of interest ("Interest Collections") and
amounts collected with respect to principal ("Principal Collections" and, with
Interest Collections, "Collections"). With respect to a Series of Securities in
which a Transferor Interest represents the interests in the related Trust Fund
not represented by such Series of Securities, Collections will be allocated
between the Transferor Interest and the Classes of such Series of Securities as
specified in the related Prospectus Supplement. The related Prospectus
Supplement will also describe the allocation or means of allocation of losses,
if any, on the related Mortgage Loans, among the Classes of Securities and, if
applicable, the Transferor Interest. Unless otherwise specified in the related
Prospectus Supplement, the Transferor Interest in a Trust Fund will not be
subordinated to the related Series of Securities.

      Interest Collections and Principal Collections on Mortgage Loans
underlying a Series of Securities will each be applied in the manner and
priority described in the related Prospectus Supplement. Certain fees and
expenses of the Trust Fund or the Servicer may be payable prior to payments due
on one or more Classes of a Series of Securities, as specified in the related
Prospectus Supplement. 

Payments of Interest

      The Securities of each Class by their terms entitled to receive interest
will bear interest (generally calculated as specified in the related Prospectus
Supplement on the basis of a 360-day year of twelve 30-day months or a 360-day
year and actual days elapsed) from the date and at the rate per annum specified,
or calculated in the method described, in the related Prospectus Supplement.
Interest on such Securities of a Series will be payable on the Distribution Date
specified in the related Prospectus Supplement. The rate of interest on
Securities of a Series may be fixed or may be variable or may change with
changes in the annual percentage rates of the Mortgage Loans included in the
related Trust Fund and/or as prepayments occur with respect to such Mortgage
Loans. A Class of Securities may be entitled to receive interest distributions
only, may not be entitled to receive any interest distributions or may be
entitled to receive only nominal interest distributions, as specified in the
related Prospectus Supplement. A Series of Securities may provide for a period
during which no or a specified amount of principal is payable except upon the
occurrence of certain events, as specified in the related Prospectus Supplement.

      Interest payable on the Securities on a Distribution Date will include all
interest accrued during the period specified in the related Prospectus
Supplement. In the event interest accrues during the calendar month preceding a


                                       15
<PAGE>   94

Distribution Date, the effective yield to Holders will be reduced from the yield
that would otherwise be obtainable if interest payable on the Securities were to
accrue through the day immediately preceding such Distribution Date. 

Payments of Principal

      On each Distribution Date for a Series, principal payments will be made to
the Holders of the Securities of such Series on which principal is then payable,
to the extent set forth in the related Prospectus Supplement. Such payments will
be made in an aggregate amount determined as specified in the related Prospectus
Supplement and will be allocated among the respective Classes of a Series in the
manner, at the times and in the priority (which may, in certain cases, include
allocation by random lot) set forth in the related Prospectus Supplement. 

Final Scheduled Distribution Date

      The Final Scheduled Distribution Date with respect to each Class of Notes
of a Series is the date no later than which principal thereof will be fully paid
and, with respect to each Class of a Series of Certificates, will be the date on
which the entire aggregate principal balance of such Class is expected to be
reduced to zero, in each case calculated on the- basis of the assumptions
applicable to such Series described in the related Prospectus Supplement. The
Final Scheduled Distribution Date for each Class of a Series will be specified
in the related Prospectus Supplement. Since payments on the Mortgage Loans will
be used to make distributions in reduction of the outstanding principal amount
of the Securities, it is likely that the actual final Distribution Date of any
such Class will occur earlier, and may occur substantially earlier, than its
Final Scheduled Distribution Date. Furthermore, with respect to a Series of
Certificates, unless otherwise specified in the related Prospectus Supplement,
as a result of delinquencies, defaults and liquidations of the Mortgage Loans in
the Trust Fund, the actual final Distribution Date of any Certificate may occur
later than its Final Scheduled Distribution Date. No assurance can be given as
to the actual prepayment experience with respect to a Series. See "--Weighted
Average Life of the Securities; Maturity and Prepayment Considerations". 

Special Redemption

      If so specified in the Prospectus Supplement relating to a Series of
Securities having other than monthly Distribution Dates, one or more Classes of
Securities of such Series may be subject to special redemption, in whole or in
part, on the day specified in the related Prospectus Supplement (a "Special
Redemption Date") if, as a consequence of prepayments on the Mortgage Loans
relating to such Securities or low yields then available for reinvestment, the
entity specified in the related Prospectus Supplement determines, based on
assumptions specified in the applicable Agreement, that the amount available for
the payment of interest that will have accrued on such Securities (the
"Available Interest Amount") through the designated interest accrual date
specified in the related Prospectus Supplement is less than the amount of
interest that will have accrued on such Securities to such date. In such event
and as further described in the related Prospectus Supplement, the Trustee will
redeem a principal amount of outstanding Securities of such Series as will cause
the Available Interest Amount to equal the amount of interest that will have
accrued through such designated interest accrual date for such Series of
Securities outstanding immediately after such redemption. 

Optional Redemption, Purchase or Termination

      The Depositor or the Servicer may, at its option, redeem, in whole or in
part, one or more Classes of Notes or purchase one or more Classes of
Certificates of any Series, on any Distribution Date under the circumstances, if
any, specified in the Prospectus Supplement relating to such Series.
Alternatively, if so specified in the related Prospectus Supplement for a Series
of Certificates, the Depositor, the Servicer, or another entity designated in
the related Prospectus Supplement may, at its option, cause an early termination
of a Trust Fund by repurchasing all of the Mortgage Loans from such Trust Fund
on or after a date specified in the related Prospectus Supplement, or on or
after such time as the aggregate outstanding principal amount of the
Certificates or Mortgage Loans, as specified in the related Prospectus
Supplement, is less than the amount or percentage specified in the related
Prospectus Supplement. Notice of such redemption, purchase or termination must
be given by the Depositor or the Trustee prior to the related date. The
redemption, purchase or repurchase price will be set forth in the related
Prospectus Supplement.


                                       16
<PAGE>   95

      In addition, the Prospectus Supplement may provide other circumstances
under which Holders of Securities of a Series could be fully paid significantly
earlier than would otherwise be the case if payments or distributions were
solely based on the activity of the related Mortgage Loans.

Weighted Average Life of the Securities; Maturity and Prepayment Considerations

      Weighted average life refers to the average amount of time that will
elapse from the date of issue of a security until each dollar of principal of
such security will be repaid to the investor. Unless otherwise specified in the
related Prospectus Supplement, the weighted average life of the Securities of a
Class will be influenced by the rate at which the amount financed under the
Mortgage Loans included in the Trust Fund for a Series is paid, which may be in
the form of scheduled amortization or prepayments.

      Prepayments on loans and other receivables can be measured relative to a
prepayment standard or model. The Prospectus Supplement for a Series of
Securities will describe the prepayment standard or model, if any, used therein
and may contain tables setting forth the projected weighted average life of each
Class of Securities of such Series and the percentage of the original principal
amount of each Class of Securities of such Series that would be outstanding on
specified Distribution Dates for such Series based on the assumptions stated in
such Prospectus Supplement, including assumptions that prepayments on the
Mortgage Loans included in the related Trust Fund are made at rates
corresponding to various percentages of the prepayment standard or model
specified in such Prospectus Supplement.

      There is, however, no assurance that prepayment of the Mortgage Loans
included in the related Trust Fund will conform to any level of any prepayment
standard or model specified in the related Prospectus Supplement. The rate of
principal prepayments on pools of loans is influenced by a variety of economic,
demographic, geographic, legal, tax, social and other factors.

      The rate of prepayments of conventional housing loans and other
receivables has fluctuated significantly in recent years. In general, however,
if prevailing interest rates fall significantly below the interest rates on the
Mortgage Loans for a Series, such loans are likely to prepay at rates higher
than if prevailing interest rates remain at or above the interest rates home by
such loans. In this regard, it should be noted that the Mortgage Loans for a
Series may have different interest rates. In addition, the weighted average life
of the Securities may be affected by the varying maturities of the Mortgage
Loans. If any Mortgage Loans for a Series have actual terms-to-stated maturity
of less than those assumed in calculating the Final Scheduled Distribution Date
of the related Securities, one or more Classes of the Series may be fully paid
prior to their respective Final Scheduled Distribution Dates, even in the
absence of prepayments and a reinvestment return higher than the Assumed
Reinvestment Rate.

      The related Prospectus Supplement may describe additional prepayment and
yield considerations with respect to the characteristics of the Mortgage Loans
included in the related Trust Fund and the Classes of Securities of the related
Series offered thereby.

                                THE TRUST FUNDS

General

      The Notes of each Series will be secured by the pledge of the assets of
the related Trust Fund, and the Certificates of each Series will represent
interests in the assets of the related Trust Fund. The Trust Fund of each Series
will include assets purchased from the Seller composed of (i) the Mortgage
Loans, (ii) amounts available from the reinvestment of payments on such Mortgage
Loans at the Assumed Reinvestment Rate, if any, specified in the related
Prospectus Supplement, (iii) any Credit Enhancement, (iv) any Mortgaged Property
that secured a Mortgage Loan but which is acquired by foreclosure or deed in
lieu of foreclosure or repossession and (v) the amount, if any, initially
deposited in the Collection Account or Distribution Account for a Series as
specified in the related Prospectus Supplement.

      The Securities will be non-recourse obligations of the related Trust Fund.
The assets of the Trust Fund specified in the related Prospectus Supplement for
a Series of Securities, unless otherwise specified in the related Prospectus
Supplement, will serve as collateral only for that Series of Securities. Holders
of a Series of Notes may only proceed against such collateral securing such
Series of Notes in the case of a default with respect to such Series of Notes
and may not proceed against any assets of the Depositor or the related Trust
Fund not pledged to secure such Notes.

      The Mortgage Loans for a Series will be sold to the Depositor by one or
more bank or non-bank direct or indirect subsidiaries of BANC ONE CORPORATION
("BANC ONE") specified in the related Prospectus Supplement (each, a "Seller"
and collectively, the "Sellers") and will be transferred by the Depositor to the
Trust Fund. The Mortgage Loans will be originated by the related Seller or
purchased by such Seller in the open market or in privately negotiated
transactions. Mortgage Loans relating to a Series will be serviced by Bank One,
N.A. or other servicer, which may be the related Seller, specified in the
related Prospectus Supplement (the "Servicer"), pursuant to a Pooling and
Servicing Agreement, with respect to a Series of Certificates or a servicing
agreement (each, a "Servicing Agreement") between the Trust Fund and Servicer,
with respect to a Series of Notes.

      As used herein, "Agreement" means, with respect to a Series of
Certificates, the Pooling and Servicing Agreement or Trust Agreement, and with
respect to a Series of Notes, the Indenture and the Servicing Agreement, as the
context requires.

      If so specified in the related Prospectus Supplement, a Trust Fund
relating to a Series of Securities may be a business trust formed under the laws
of the state specified in the related Prospectus Supplement pursuant to a trust
agreement (each, a "Trust Agreement") between the Depositor and the trustee of
such Trust Fund specified in the related Prospectus Supplement.

      With respect to each Trust Fund, prior to the initial offering of the
related Series of Securities, the Trust Fund will have no assets or liabilities.
No Trust Fund is expected to engage in any activities other than acquiring,
managing and holding the related Mortgage Loans and other assets contemplated
herein and in the related Prospectus Supplement and the proceeds thereof,
issuing Securities and making payments and distributions thereon and certain
related activities. No Trust Fund is expected to have any source of capital
other than its assets and any related Credit Enhancement. 

The Mortgage Loans

      The Mortgage Loans for a Series will consist of revolving home equity
loans and lines of credit (the "Mortgage Loans") secured by mortgages primarily
on single family properties (the "Mortgaged Properties") which may be
subordinated to other mortgages on the same Mortgaged Property. The Mortgage
Loans may have fixed interest rates or adjustable interest rates and may provide
for other payment characteristics, as described below and in the related
Prospectus Supplement.

      As more fully described in the related Prospectus Supplement, interest on
each Mortgage Loan, excluding introductory rates offered from time to time
during promotional periods, may be computed and payable monthly on the average
daily outstanding principal balance of such loan. Principal amounts on the
Mortgage Loans may be drawn down (up to a maximum amount as set forth in the
related Prospectus Supplement) or repaid under each Mortgage Loan from time to
time. If so specified in the related Prospectus Supplement, new draws by
borrowers under the Mortgage Loans will automatically become part of the Trust
Fund for a Series. As a result, the aggregate 


                                       18
<PAGE>   97

balance of the Mortgage Loans will fluctuate from day to day as new draws by
borrowers are added to the Trust Fund and principal payments are applied to such
balances and such amounts will usually differ each day, as more specifically
described in the related Prospectus Supplement. Under certain circumstances, a
borrower may choose an interest only payment option and is obligated to pay only
the amount of interest which accrues on the loan during the billing cycle. An
interest only payment option may be available for a specified period before the
borrower must begin paying at least the minimum monthly payment of a specified
percentage of the average outstanding balance of the loan or, if so specified in
the related Prospectus Supplement, such interest only period may be extended for
one or more additional periods.

      The Mortgaged Properties will include primarily one- to four-family
residential housing, including Condominium Units and Cooperative Dwellings and
may consist of detached individual dwellings, individual condominiums,
townhouses, duplexes, row houses, individual units in planned unit developments
and other attached dwelling units. Each Mortgaged Property will be located on
land owned in fee simple by the borrower or on land leased by the borrower for a
term at least ten years (unless otherwise provided in the related Prospectus
Supplement) longer than the term of the related Mortgage Loan. Attached
dwellings may include owner-occupied structures where each borrower owns the
land upon which the unit is built, with the remaining adjacent land owned in
common or dwelling units subject to a proprietary lease or occupancy agreement
in a cooperatively owned apartment building.

      Unless otherwise specified in the related Prospectus Supplement, Mortgages
on Cooperative Dwellings consist of a lien on the shares issued by such
Cooperative Dwelling and the proprietary lease or occupancy agreement relating
to such Cooperative Dwelling.

      The aggregate principal balance of Mortgage Loans secured by Mortgaged
Properties that are owner-occupied will be disclosed in the related Prospectus
Supplement. Unless otherwise specified in the Prospectus Supplement, the sole
basis for a representation that a given percentage of the Mortgage Loans are
secured by Mortgaged Property that is owner-occupied will be either (i) the
making of a representation by the Mortgagor at origination of the Mortgage Loan
either that the underlying Mortgaged Property will be used by the Mortgagor for
a period of at least six months every year or that the Mortgagor intends to use
the Mortgaged Property as a primary residence, or (ii) a finding that the
address of the underlying Mortgaged Property is the Mortgagor's mailing address
as reflected in the Servicer's records. To the extent specified in the related
Prospectus Supplement, the Mortgaged Properties may include non-owner occupied
investment properties and vacation and second homes.

      Unless otherwise specified in the related Prospectus Supplement, the
initial Combined Loan-to-Value Ratio of a Mortgage Loan is computed in the
manner described in the related Prospectus Supplement, taking into account the
amounts of any related senior mortgage loans.

      Additional Information. The selection criteria which shall apply with
respect to the Mortgage Loans for a Series, including, but not limited to, the
Combined Loan-to-Value Ratios or Loan-to-Value Ratios, as applicable, original
terms to maturity and delinquency information, will be specified in the related
Prospectus Supplement.

      The Mortgage Loans for a Series may include Mortgage Loans that do not
amortize their entire principal balance by their stated maturity in accordance
with their terms and require a balloon payment of the remaining principal
balance at maturity, as specified in the related Prospectus Supplement. As
further described in the related Prospectus Supplement, the Mortgage Loans for a
Series may include Mortgage Loans that do not have a specified stated maturity.

      The related Prospectus Supplement for each Series will provide information
with respect to the Mortgage Loans as of the Cut-off Date, including, among
other things, (a) the aggregate unpaid principal balance of the Mortgage Loans;
(b) the range and weighted average Loan Rate on the Mortgage Loans and, in the
case of adjustable rate Mortgage Loans, the range and weighted average of the
current Loan Rates and the Lifetime Rate Caps, if any; (c) the range and average
outstanding principal balance of the Mortgage Loans; (d) the weighted average
original and remaining term-to-stated maturity of the Mortgage Loans and the
range of original and remaining terms-to-stated maturity, if applicable; (e) the
range and weighted average of Combined Loan-to-Value Ratios or Loan-to-Value
Ratios for the Mortgage Loans, as applicable; (f) the percentage (by outstanding
principal balance as of the Cut-off Date) of Mortgage Loans that accrue interest
at adjustable or fixed interest rates; (g) any special hazard insurance policy
or bankruptcy bond or other enhancement relating to the Mortgage Loans; (h) the
geographic distribution of the Mortgaged Properties securing the Mortgage Loans;
(i) the lien priority of the Mortgage Loans; (j) the credit limit utilization
rate of the Mortgage Loans; and (k) the delinquency status and year 


                                       19
<PAGE>   98

of origination of the Mortgage Loans. The related Prospectus Supplement will
also specify any other limitations on the types or characteristics of Mortgage
Loans for a Series.

      If information of the nature described above respecting the Mortgage Loans
is not known to the Depositor at the time the Securities are initially offered,
approximate or more general information of the nature described above will be
provided in the Prospectus Supplement and additional information will be set
forth in a Current Report on Form 8-K to be available to investors on the date
of issuance of the related Series and to be filed with the Commission within 15
days after the initial issuance of such Securities. 

Collection and Distribution Accounts

      A separate Collection Account will be established by the Trustee or the
Servicer, in the name of the Trustee, for each Series of Securities for receipt
of the amount of cash, if any, specified in the related Prospectus Supplement to
be initially deposited therein by the Depositor, all amounts received on or with
respect to the Mortgage Loans and, unless otherwise specified in the related
Prospectus Supplement, income earned thereon. Certain amounts on deposit in such
Collection Account and certain amounts available pursuant to any Credit
Enhancement, as provided in the related Prospectus Supplement, will be deposited
in a related Distribution Account, which will also be established by the Trustee
for each such Series of Securities, for distribution to the related Holders.
Unless otherwise specified in the related Prospectus Supplement, the Trustee
will invest the funds in the Collection and Distribution Accounts in Eligible
Investments maturing, with certain exceptions, not later, in the case of funds
in the Collection Account, than the day preceding the date such funds are due to
be deposited in the Distribution Account or otherwise distributed and, in the
case of funds in the Distribution Account, than the day preceding the next
Distribution Date for the related Series of Securities. Eligible Investments
include, among other investments, obligations of the United States and certain
agencies thereof, federal funds, certificates of deposit, commercial paper,
demand and time deposits and banker's acceptances, certain repurchase agreements
of United States government securities and certain guaranteed investment
contracts, in each case, acceptable to the Rating Agency.


                                       20
<PAGE>   99

                               CREDIT ENHANCEMENT

      If stated in the Prospectus Supplement relating to a Series of Securities,
simultaneously with the assignment by the Depositor of the Mortgage Loans to the
Trustee, the Depositor will obtain an irrevocable letter of credit, surety bond
or insurance policy, issue Subordinate Securities or obtain any other form of
enhancement or combination thereof (collectively, "Credit Enhancement") in favor
of the Trustee on behalf of the holders of the related Series or designated
Classes of such Series from an institution or by other means acceptable to the
Rating Agency. The Credit Enhancement will support the payment of principal and
interest on the Securities, and may be applied for certain other purposes to the
extent and under the conditions set forth in such Prospectus Supplement. Credit
Enhancement for a Series may include one or more of the following forms, or such
other form as may be specified in the related Prospectus Supplement. If so
specified in the related Prospectus Supplement, any of such Credit Enhancement
may be structured so as to protect against losses relating to more than one
Trust Fund, in the manner described therein. 

Subordinate Securities

      If specified in the related Prospectus Supplement, Credit Enhancement for
a Series may consist of one or more Classes of Subordinate Securities. The
rights of Holders of such Subordinate Securities to receive distributions on any
Distribution Date will be subordinate in right and priority to the rights of
Holders of Senior Securities of the Series, but only to the extent described in
the related Prospectus Supplement. 

Financial Guaranty Insurance Policy

      If so specified in the related Prospectus Supplement, a financial guaranty
insurance policy or surety bond (a "Securities Insurance Policy") may be
obtained and maintained for a Class or Series of Securities. The issuer of the
Securities Insurance Policy (the "Insurer") will be described in the related
Prospectus Supplement and a copy of the form of Securities Insurance Policy will
be filed with the related Current Report on Form 8-K.

      Unless otherwise specified in the related Prospectus Supplement, a
Securities Insurance Policy will be unconditional and irrevocable and will
guarantee to Holders of the applicable Securities that an amount equal to the
full amount of distributions due to such Holders will be received by the Trustee
or its agent on behalf of such Holders for distribution on each Payment Date.

      The specific terms of any Securities Insurance Policy will be set forth in
the related Prospectus Supplement. A Securities Insurance Policy may have
limitations and generally will not insure the obligation of the Depositors or
any Originator to purchase or substitute for a defective Mortgage Loan and will
not guarantee any specific rate of principal prepayments.

      Unless otherwise specified in the related Prospectus Supplement, the
Insurer will be subrogated to the rights of each Holder to the extent the
Insurer makes payments under the Securities Insurance Policy.

Insurance

      If stated in the related Prospectus Supplement, Credit Enhancement for a
Series may consist of special hazard insurance policies, bankruptcy bonds and
other types of insurance relating to the Mortgage Loans, as described below and
in the related Prospectus Supplement.

      Pool Insurance Policy. If so specified in the Prospectus Supplement
relating to a Series of Securities, the Depositor will obtain a pool insurance
policy for the Mortgage Loans in the related Trust Fund. The pool insurance
policy will cover any loss (subject to the limitations described in a related
Prospectus Supplement) by reason of default, but will not cover the portion of
the principal balance of any Mortgage Loan that is required to be covered by any
primary mortgage insurance policy. The amount and terms of any such coverage
will be set forth in the related Prospectus Supplement.

      Special Hazard Insurance Policy. If so specified in the Prospectus
Supplement relating to a Series of Securities, the Depositor will obtain a
special hazard insurance policy for the Mortgage Loans in the related Trust
Fund. Although the terms of such policies vary to some degree, a special hazard
insurance policy typically provides that, where there has been damage to the
Mortgaged Property securing a defaulted or foreclosed Mortgage Loan (title to
which has been acquired by the insured) and to the extent such damage is not
covered by the standard hazard 


                                       21
<PAGE>   100

insurance policy or any flood insurance policy, if applicable, required to be
maintained with respect to such Mortgaged Property, or in connection with
partial loss resulting from the application of the coinsurance clause in a
standard hazard insurance policy, the special hazard insurer will pay the lesser
of (i) the cost of repair or replacement of such Mortgaged Property or (ii) upon
transfer of such Mortgaged Property to the special hazard insurer, the unpaid
principal balance of such Mortgage Loan at the time of acquisition of such
Mortgaged Property by foreclosure or deed in lieu of foreclosure, plus accrued
interest to the date of claim settlement and certain expenses incurred by the
Servicer with respect to such Mortgaged Property. If the unpaid principal
balance plus accrued interest and certain expenses is paid by the special hazard
insurer, the amount of further coverage under the special hazard insurance
policy will be reduced by such amount less any net proceeds from the sale of
such Mortgaged Property. Any amount paid as the cost of repair of such Mortgaged
Property will reduce coverage by such amount. Special hazard insurance policies
typically do not cover losses occasioned by war, civil insurrection, certain
governmental actions, errors in design, faulty workmanship or materials (except
under certain circumstances), nuclear reaction, flood (if the Mortgaged Property
is in a federally designated flood area), chemical contamination and certain
other risks.

      Restoration of the Mortgaged Property with the proceeds described under
(i) above is expected to satisfy the condition under any pool insurance policy
that such Mortgaged Property be restored before a claim under such pool
insurance policy may be validly presented with respect to the defaulted Mortgage
Loan secured by such Mortgaged Property. The payment described under (ii) above
will render unnecessary presentation of a claim in respect of such Mortgage Loan
under any pool insurance policy. Therefore, so long as such pool insurance
policy remains in effect, the payment by the special hazard insurer of the cost
of repair or of the unpaid principal balance of the related Mortgage Loan plus
accrued interest and certain expenses will not affect the total insurance
proceeds paid to Holders of the Securities, but will affect the relative amounts
of coverage remaining under the special hazard insurance policy and pool
insurance policy.

      Bankruptcy Bond. In the event of a bankruptcy of a borrower, the
bankruptcy court may establish the value of the Mortgaged Property securing the
related Mortgage Loan at an amount less than the then outstanding principal
balance of such Mortgage Loan. The amount of the secured debt could be reduced
to such value, and the holder of such Mortgage Loan thus would become an
unsecured creditor to the extent the outstanding principal balance of such
Mortgage Loan exceeds the value so assigned to the Mortgaged Property by the
bankruptcy court. In addition, certain other modifications of the terms of a
Mortgage Loan can result from a bankruptcy proceeding. See "CERTAIN LEGAL
ASPECTS OF MORTGAGE LOANS." If so provided in the related Prospectus Supplement,
the Depositor or other entity, specified in the related Prospectus Supplement
will obtain a bankruptcy bond or similar insurance contract (the "bankruptcy
bond") covering losses resulting from proceedings with respect to borrowers
under the Bankruptcy Code. The bankruptcy bond will cover certain losses
resulting from a reduction by a bankruptcy court of scheduled payments of
principal of and interest on a Mortgage Loan or a reduction by such court of the
principal amount of a Mortgage Loan and will cover certain unpaid interest on
the amount of such a principal reduction from the date of the filing of a
bankruptcy petition.

      The bankruptcy bond will provide coverage in the aggregate amount
specified in the related Prospectus Supplement for all Mortgage Loans in the
Trust Fund for such Series. Such amount will be reduced by payments made under
such bankruptcy bond in respect of such Mortgage Loans, unless otherwise
specified in the related Prospectus Supplement, and will not be restored.

Reserve Funds

      If so specified in the Prospectus Supplement relating to a Series of
Securities, the Depositor will deposit into one or more funds to be established
with the Trustee as part of the Trust Fund for such Series or for the benefit of
any Enhancer with respect to such Series (the "Reserve Funds") cash, a letter or
letters of credit, cash collateral accounts, Eligible Investments, or other
instruments meeting the criteria of each Rating Agency rating any Series of the
Securities in the amount specified in such Prospectus Supplement. In the
alternative or in addition to such deposit, a Reserve Fund for a Series may be
funded over time through application of all or a portion of the excess cash flow
from the Mortgage Loans for such Series, to the extent described in the related
Prospectus Supplement. If applicable, the initial amount of the Reserve Fund and
the Reserve Fund maintenance requirements for a Series of Securities will be
described in the related Prospectus Supplement.


                                       22
<PAGE>   101

      Amounts withdrawn from any Reserve Fund will be applied by the Trustee to
make payments on the Securities of a Series, to pay expenses, to reimburse any
Enhancer or for any other purpose, in the manner and to the extent specified in
the related Prospectus Supplement.

      Amounts deposited in a Reserve Fund will be invested by the Trustee, in
Eligible Investments maturing no later than the day specified in the related
Prospectus Supplement.

Overcollateralization

      If so specified in the related Prospectus Supplement, Credit Enhancement
may be provided by overcollateralization created by the application of a portion
of interest collections to the payment of principal of the related Securities or
otherwise. The reduction of the principal balance of the Securities relative to
the outstanding balance of the underlying Mortgage Loans creates
overcollateralization and provides additional protection to the Holders of such
Securities. 

Other Credit Enhancement

      Credit enhancement may also be provided for a Series of Securities in the
form of overcollateralization, surety bond, insurance policy or other type of
credit enhancement approved by the applicable Rating Agencies to cover one or
more risks with respect to the Mortgage Loans or the Securities, as specified in
the related Prospectus Supplement.

                THE DEPOSITOR, THE SERVICER AND THE ORIGINATORS

General

      The Depositor was incorporated in the State of Ohio on May 7, 1996 for the
limited purpose of purchasing mortgage loans, automobile loans and other
receivables, transferring such loans or receivables to third parties, forming
trusts and engaging in related activities. All of the outstanding common stock
of the Depositor is owned by BANC ONE. 

The Banc One Consumer Lending Division Home Equity Program

      BANC ONE, through its affiliated Banks, has originated variable rate home
equity revolving lines of credit since the early 1980's. During the past several
years BANC ONE has undertaken a transition from managing its business activities
at the affiliate (legal entity) level to centralized management of such business
activities by nationally focused lines of business. As part of this transition,
all home equity lending originated directly with consumers was centralized in
early 1997 and is currently managed by the Banc One Retail Group's Consumer
Lending Division ("Consumer Lending"). Consumer Lending has created national
business units including marketing, product management, risk management, credit
underwriting, loan servicing and collections to manage its credit related
activities. To the extent material, the related Prospectus Supplement will
specify the amount of outstanding home equity revolving lines of credit and home
equity loans managed by Consumer Lending. 

Home Equity Lines of Credit

      Home equity lines of credit ("HELOCs") consist of variable or fixed rate,
open-ended, revolving lines of credit secured by a lien position against the
available equity of a borrower's related residential real estate Mortgaged
Property. A borrower may draw on a HELOC by writing a check, telephoning a
customer service representative and requesting funds to be transferred to a
pre-authorized depository account, requesting a cashier's check at a BANC ONE
banking center, or, with respect to certain HELOCs, credit card purchase
authorization.

      HELOCs originated by Consumer Lending are secured by a lien on the related
Mortgaged Property subject to maximum loan-to-value ("LTV") limitations.
Currently, Consumer Lending offers its customers credit lines that allow them to
borrow against the value of the real estate up to either an 80% LTV (Option 1)
or a 100% LTV (Option 2) limit. The contractual term of a HELOC consists of a
revolving open-ended period (the "Draw Period"), during which borrowings may be
made periodically, and a period during which the contract converts to a fixed
payment, variable rate, amortizing closed-ended loan (the "Repayment Period").
The contractual term of the Draw Period is based upon the LTV provided by the
HELOC loan agreement. For Mortgage Loans with LTVs equal to or 


                                       23
<PAGE>   102

less than 80%, the Draw and Repayment Periods are 10 years and 10 years,
respectively. For Mortgage Loans with LTVs greater than 80% and less than or
equal to 100%, the Draw and Repayment Periods are 5 years and 10 years,
respectively. Draw periods may, at the election of Consumer Lending, be
extended.

      During the Draw Period, the required minimum monthly payment is equal to
the greater of: i) 1% of the outstanding balance; ii) $100.00; or iii) the
interest accrued plus any annual fee assessments, late charges, administrative
charges, and credit or other insurance charges ("Assessed Fees"). At the
beginning of the Repayment Period, the required monthly payment is calculated
based on principal, interest, and Assessed Fees related to the amortization of
the outstanding balance due using the APR. Although the monthly amount due will
remain constant throughout the repayment period, the number of monthly payments
can either increase or decrease according to fluctuations in the variable annual
percentage rate and Assessed Fees. Payments are applied to a customer's account
first to interest, then to principal due, and then to Assessed Fees. Accounts
are generally identified as delinquent when less than 90% of the required
payment is remitted to the servicing agent.

      Consumer Lending customers have several channels through which payments
can be made to their account including i) payment by check to lockbox remittance
processing centers, ii) payments by check submitted to tellers at the local BANC
ONE banking center, iii) automated debits to pre-authorized depository accounts,
and iv) automated teller machines.

      Interest rates for HELOCs are established at a product level and are the
responsibility of a national pricing committee of Consumer Lending. Factors
considered in the price setting process include, among other things, targeted
product profitability and related returns, market competition, market
penetration, trends in market interest rates, and potential credit losses.
Pricing tiers are based on credit/bureau scoring techniques and the balance size
of the account being originated. This accommodates setting prices based on
credit risk characteristics ("risk-adjusted pricing") and the cost to acquire
new customers.

      Consistent with industry practice, Consumer Lending utilizes introductory
offerings including interest rates ("Promo Rates") and waiving closing costs to
acquire new accounts. Promo rates are occasionally offered by Consumer Lending,
which may either be a variable introductory discount or fixed introductory rate.
The term of a Promo Rate may range from 1 to 12 months; however, the majority of
Promo Rates are offered for 6 months beginning at the inception of the Mortgage
Loan.

      In general, HELOCs bear interest at a variable rate and generally are
subject to a maximum per annum interest rate of between 18% to 25%, depending
upon governing state laws. The interest rate on all HELOCs originated after
April 1,1997 adjusts monthly. The daily periodic rate is 1/365th (1/366th in the
case of leap years) of the APR, which represents the sum of a contractual
defined index (the "Index") plus a fixed percentage specified in the related
Agreement (the "Gross Margin"). Interest is calculated at a rate applied to the
daily balance of the account for each day of the billing cycle (the "Loan
Rate"). The index for all loans originated after April 1, 1997 is the average
weekly Bank Prime Loan Rate as published by the Board of Governors of the
Federal Reserve System (the "Index"). When a variable introductory discount
("Promo Discount") is offered, the Promo Rate is equal to the Loan Rate less the
Promo Discount.

      The HELOCs may permit the customer to convert either the entire
outstanding balance due or any portion thereof, to a fixed rate closed-end loan
("Lock Feature"). The Lock Feature, if any, may be exercised during the Draw
Period, subject to certain limitations. The Lock Feature allows for a repayment
schedule of up to but not exceeding 10 years. When the Lock Feature is
exercised, the utilized portion of the HELOC credit line is equal to the
amortizing "locked" principal balance plus the revolving principal balance, the
combination of which can not exceed the established credit limit under the loan.

Product Management & Marketing Activities

      The Mortgage Loans were or will be originated by one or more of the
Sellers (managed by Consumer Lending) utilizing a variety of marketing
strategies and product delivery channels. Product management and marketing
activities are conducted on a national level, with adjustments in response to
local market competitive offerings and pricing practices as reported by field
marketing managers and the banking center network. Marketing strategies are
developed on an annual basis and may include a combination of television, radio,
newspaper and outdoor media, direct mailings to existing and prospective
customers, banking center merchandising and other sales supporting tools.
Consumer Lending also develops various types of promotions to activate accounts
or increase utilization, including special balance transfer offers, sweepstakes,
promotional Lock Feature rates and related 


                                       24

programs. Loans may be originated through BANC ONE's banking center distribution
network or Consumer Lending's Loan-by-Phone ("LBP") call centers. LBP centers
are located in Milwaukee, Wisconsin, Houston, Texas, and Tempe, Arizona, and are
intended to provide sales and service to Consumer Lending's customers, utilizing
technology and scoring techniques to reduce turnaround time to approve
applications, expedite processing and provide convenient customer-oriented
closings. Additionally, Consumer Lending may originate HELOCs within the banking
center distribution network or as part of a national equity lending program
throughout the United States. Additionally, Consumer Lending may utilize a
variety of brand names to promote its HELOC products, including Bank One or
First USA. 

Underwriting

      HELOCs originated through Consumer Lending are subject to standardized
underwriting criteria and approval processes. HELOCs are underwritten at a
minimum of $5,001 up to $250,000, with LTVs up to 100%. Single family residences
may be financed up to 100% LTV; attached single family (condo, townhouse, patio
homes) residences may be financed up to 70% LTV; mobile homes and lots may be
financed up to 80% LTV if the mobile homes are permanently affixed to the
Mortgaged Property; and second homes may be financed up to 70% LTV. HELOCs are
not available on any non-owner occupied properties or owner-occupied 2-4 family
properties. Generally all HELOCs are in a second lien position; however, some
non-purchase first position liens and third positions may exist. All third lien
positions are reviewed by a senior lender.

      Each applicant for a HELOC is required to complete an application, which
generally lists the applicant's mortgage liabilities, income, employment history
and other demographic and personal information. A customer may submit an
application through one of several distribution channels such as with a
relationship banker at a local banking center, telephoning a LBP call center, or
telephoning a customer service representative at a teleservicing center. If the
application indicates sufficient income and equity in the related real estate
Mortgaged Property to justify extending a HELOC, a further credit investigation
will be conducted. This investigation is part of Consumer Lending's underwriting
activities managed by Consumer Lending's Credit Services unit and performed at
one of three processing sites located in Milwaukee, Wisconsin, Houston, Texas,
or Tempe, Arizona, utilizing policies developed and monitored jointly with
Consumer Lending's Risk Management group.

      The credit approval process utilizes credit scoring and related techniques
and subjective assessments by experienced underwriters. Underwriters analyze the
equity position of the requested loan (including both the priority of the lien
and the combined loan-to-value ratio) and the applicant's creditworthiness. The
evaluation of creditworthiness is designed to assess the applicant's ability and
willingness to repay the loan. This evaluation primarily consists of (i)
reviewing and verifying customer and demographic information; (ii) obtaining and
reviewing an independent credit bureau report; (iii) reviewing the applicant's
credit bureau score and, if applicable, a BANC ONE proprietary custom credit
score; (iv) reviewing and verifying the applicant's employment and reported
income through a review of recent W-2's, pay stubs or telephone verification by
the applicant's current employer or assessments of tax returns and financial
statements; (v) evaluating the applicant's gross debt to income ratio; (vi)
reviewing the title status either by a written title search or insured title
policy to ensure that all liens (including Mortgaged Property taxes), except for
senior liens, are paid off prior to or at time of settlement of the loan; (vii)
obtaining and evaluating the value of the real estate through independent
appraisals or valuations; and (viii) evaluating flood risk and verifying flood
insurance coverage, if applicable.

      Credit bureau information is reviewed for minimum acceptable credit scores
and consistent record of timely payments and to identify any major negative
events such as bankruptcy, repossession, foreclosure or a delinquency of greater
than 90 days, that have occurred within the past 5 years. Minimum acceptable
credit bureau scores are established by state through an on-going risk
management and credit scoring process. Applicants with a recent negative event
may be eligible for an exception, but any loans made pursuant to such exception
are limited to a maximum LTV of 80%. In some regions, a custom scorecard is used
in addition to credit bureau reports. Each area or region may have different
cutoffs based on specific data or market indicators determined through risk
analysis. The existing credit scoring process and related scorecards are
reviewed on a regular basis. Beginning in April 1998 and staggered in phases
thereafter, a national scorecard will be implemented, standardizing the data
gathering and assigning scores. Each applicant is assigned a grade or tier based
on their score(s) and associated risk. Most policies are linked to the tiers as
a risk factor.

      Beginning in 1998, Consumer Lending implemented processes allowing certain
applicants to receive final loan approval through expedited real estate
appraisal, income, title searches and other related verifications


                                       25
<PAGE>   104

("FASTRAC"). FASTRAC applications are identified during the initial process
based on the completeness of documentation provided with the application.
Although subject to all of the policies, procedures and authorization controls
required by Consumer Lending underwriting standards, the process is intended to
improve turnaround and overall customer service.

      The extent of required income verification is determined based on an
applicant's assessed credit risk, loan amount, whether or not self-employed, and
the extent of unearned income. If salaried, income is verified through W-2's or
current pay stubs. For applicants with superior credit risk assessments (Tier
A1), income is verified if the requested amount exceeds $250,000. Income
verification is required for requests greater than $50,000 when an applicant's
credit risk assessment meets pre-defined score cutoffs (Tier A2 or A3). Income
for all other applicants is verified (Tier A4 or below). If unearned income is
greater than 50% of declared income or if the source of income is
self-employment and the requested loan amount exceeds $20,000, current
year-to-date and two previous year's financial statements, accompanied by
federal tax returns, are required.

      A gross debt to income ratio test is applied to each applicant by dividing
the applicant's monthly payments on all existing obligations, including the
proposed HELOC payment (based on a fully funded balance), by the applicant's
gross monthly income. Maximum ratios are assigned by tier as follows: 55% (Tier
A1); 50% (Tier A2); 45% (Tier A3); and 40% (Tier A4).

      Valuation methods are based upon the amount requested by the applicant and
the expected loan-to-value ratio ("LTV"). Appraisal values are generally
determined in one of several methods: (i) an appraisal completed on Fannie Mae
("FNMA") form 1004 ("Uniform Residential Appraisal Request" or "URAR"),
consisting of a complete inspection by a qualified appraiser which is usually
performed if the amount of the HELOC requested by the applicant is greater than
$ 100,000 with an LTV of greater than 80% or for any HELOC if the amount
requested is greater than $250,000 or is secured by certain types of Mortgaged
Property, (ii) by reference to the assessed value of the related real estate
Mortgaged Property shown on the tax records of applicable governing units, if
the Mortgaged Property is located in a county and State in which Consumer
Lending, in its discretion, has determined is a reliable indicator of the
appraised value of the Mortgaged Property, (iii) a "drive-by" appraisal,
completed on Freddie Mac ("FHLMC") form 704, consisting of an evaluation of
comparable properties on the basis of a visual inspection of the exterior of the
related real estate Mortgaged Property, (iv) a broker's opinion of value or
HUD-1 Settlement Statement that are less than 12 months old; or (v) through
automated appraisal techniques utilizing pre-approved national vendors to
validate and verify valuations of the related real estate properties. To qualify
for automated appraisals, the requested loan amount must be less than $100,000
and meet certain criteria, including Mortgaged Property type classification.

      A title search is performed covering at least the period from the
conveyance of the related real estate Mortgaged Property to the applicant from
the last owner before the applicant. A full title search may be requested
depending upon the size of the amount requested by the applicant. Title
insurance is not required to be obtained by the borrower unless title defects
are identified or the requested loan amount exceeds $150,000. An insured title
policy (ALTA policy or its equivalent) which insures title for both lender and
owner is required on newly constructed homes less than six months old on which
the lien will be in first position and on all purchase money transactions.

      Consumer Lending requires a flood determination on all improved Mortgaged
Property. Flood insurance, with the appropriate Affiliated Bank named as loss
payee, is required on all properties located in a Special Flood Hazard Area as
determined by the Federal Emergency Management Agency (FEMA), in an amount at
least equal to the lesser of the total encumbrances up to the maximum allowed
under the National Flood Insurance Program (NFIP), or replacement coverage or
value of the dwelling and improvements as defined by the evaluation method used.
Proof of flood insurance is required by providing either a copy of the existing
flood insurance policy or a copy of the application for flood insurance and
related proof of payment. Any Mortgaged Property located in a flood zone is
monitored until maturity.

      In addition, adequate fire and casualty insurance coverage is required on
all dwellings and structural improvements with the appropriate Affiliated Bank
named as loss payee on all policies. The minimum coverage is the lesser of total
encumbrances or replacement coverage, or value of the dwelling and improvements.
No HELOC may close without a properly completed agreement to provide insurance
coverage. Verbal confirmation from the agent is required. Once verification has
taken place, no additional monitoring or forced placement is performed.


                                       26
<PAGE>   105

      Consumer Lending has implemented an internal quality control process to
ensure adherence to policies and underwriting standards. The quality control
process includes self-audits of underwriting decisions, real estate verification
processes, documentation and other activities on samples of applications and
approved loans. Credit policy exceptions are monitored regularly by senior
management of Credit Services and Consumer Lending, as appropriate. 

Mortgage Loan Servicing

      As part of BANC ONE's transition from managing its business activities on
an Affiliate (legal entity) level to centralized, nationally focused, lines of
business, loan servicing activities were consolidated and centralized. Consumer
Lending continues to standardize and redesign operational processes to improve
customer service and internal controls.

      HELOCs are serviced by one of four regional processing centers operated by
Banc One Services Corporation ("BOSC"), a wholly-owned subsidiary of BANC ONE,
and located in Louisville and Lexington, Kentucky; Fort Worth, Texas; and Mesa,
Arizona. BOSC carries out loan servicing operations for most BANC ONE
subsidiaries under various servicing contracts between BOSC and the applicable
subsidiary. Consumer Lending's Loan Servicing unit ("Custodial Operations") is
currently responsible for management of the processing centers. Custodial
Operations has established practices and procedures governing the servicing of
owned and serviced accounts related to: funding and recordation of originated
loans, note and collateral documentation, filing verification and control,
statement and payment processing and preparation of tax related information.

      Billing statements are mailed monthly which detail an account credit
limit, loan balance, interest rate applied, payment due date, minimum payment
amount, past due amounts, interest rate changes, and the available credit line.
Customers may utilize several payment methods such as by submitting checks to a
lock-box located at one of the loan processing centers; submitting checks to a
teller at a local banking center; pre-authorized automated debit from a
depository account; wire transfers; or automated teller machines.

Collections/Portfolio Management

      Collections of HELOCs originated by Consumer Lending through the
Affiliated Banks is centrally managed by Consumer Lending's Portfolio Asset
Management unit ("PAM") at three collection sites located in Akron, Ohio,
Waukesha, Wisconsin and Tempe, Arizona. While the collection sites are managed
by Consumer Lending, they are currently owned by each of Bank One, N.A., Bank
One Wisconsin, and Bank One, Arizona, N.A., respectively. Collection management
for receivables originated by Bank One, N.A. and its predecessor banks located
in the state of Ohio are provided by Bank One, N.A. During the period from
mid-1995 through early-1997, the collections functions for HELOCs originated by
the Ohio banks was transferred to Bank One, N.A. Bank One, Wisconsin currently
performs collections functions for HELOCs originated by Bank One, Wisconsin and
its predecessor banks located in the state of Wisconsin, HELOCs originated by
Bank One, Indiana, N.A. and its predecessor banks located in the state of
Indiana, HELOCs originated by Bank One, Illinois, N.A. and its predecessor banks
located in the state of Illinois, HELOCs originated by Bank One, Kentucky, N.A.
and its predecessor banks located in the state of Kentucky and HELOCs originated
by Bank One, Louisiana, N.A. and its predecessor banks located in the state of
Louisiana. During the period from late 1995 through early 1998, the collections
functions of the HELOCs originated by these Wisconsin, Indiana, Illinois,
Kentucky and Louisiana banks was transferred to Bank One, Wisconsin. Bank One,
Arizona, N.A. currently performs collections functions for HELOCs originated by
Bank One, Arizona, N.A. and its predecessor banks located in the state of
Arizona, HELOCs originated by Bank One, Oklahoma, N.A. and its predecessor banks
located in the state of Oklahoma, HELOCs originated by Bank One, Utah, N.A. and
its predecessor banks located in the state of Utah, HELOCs originated by Bank
One, Colorado, N.A. and its predecessor banks located in the state of Colorado,
and HELOCs originated by Bank One, Texas, N.A. and its predecessor banks located
in the State of Texas. During 1997, the collections functions of HELOCs
originated by the Arizona, Oklahoma, Utah, Colorado and Texas banks was
transferred to Bank One, Arizona, N.A. The transfers of collection management
functions are substantially complete. In addition, BANC ONE and its affiliates
from time to time may acquire portfolios, which may be serviced by one of these
affiliates. Although Consumer Lending does not contemplate any servicing
disruptions developing as a result of these acquisitions, there can be no
assurance that such interruptions will not occur.


                                       27

      The PAM has established standard policies governing the collection of
owned and serviced loans. Collections management primarily includes the
supervision of delinquent loans, loss mitigation efforts, foreclosure
proceedings and, if applicable, the disposition of mortgaged properties.

      The PAM utilizes a variety of collections management programs and tools to
monitor and collect delinquent accounts, mitigate account losses, and recover
assets previously written off. Account monitoring begins once an account becomes
past due.

      Collection efforts for delinquent accounts are initiated based on
behavioral and credit risk scoring. PAM uses the Triad Collection Activity
Prioritization System (the "Triad System") to manage the timing and extent of
collection efforts. The Triad System uses customer and account information to
define a variety of effective and efficient collection strategies by stratifying
delinquent accounts as low, medium or high risk based on payment history,
product type, and other account characteristics. Consumer Lending's policy is to
suspend drawing privileges on overdue loans when collection efforts are
initiated. Draw privileges are permanently suspended once an account becomes 60
days delinquent. Permanently suspended draw privileges may be reinstated with
management approval.

      In accordance with industry practice, the Custodial Operations reports
accounts that are 30 days past due to the credit reporting bureaus. During the
period when the loan is 45 to 59 days delinquent, Consumer Lending sends notice
of default informing the borrower of intent to initiate foreclosure proceedings
on the Mortgaged Property within certain timeframes as allowed by law. Senior
lien holders, if any, may be contacted to determine the status of those liens.
Broker's price opinions, appraisals, and Mortgaged Property inspections may be
conducted once an account reaches 60 days past due.

      When the notice of default to the borrower expires, the PAM determines
whether to initiate foreclosure proceedings. Analyses are performed and, at 90
days past due, foreclosure proceedings are initiated, if appropriate. If
accounts are determined to be collectable, collection managers may delay
foreclosure proceedings.

                          SERVICING OF MORTGAGE LOANS

General

      Customary servicing functions with respect to Mortgage Loans comprising
the Mortgage Loans in the Trust Fund will be provided by the Servicer directly
pursuant to the related Servicing Agreement or Pooling and Servicing Agreement,
as the case may be, with respect to a Series of Securities. 

Collection Procedures; Escrow Accounts

      The Servicer will make reasonable efforts to collect all payments required
to be made under the Mortgage Loans and will, consistent with the terms of the
related Agreement for a Series and any applicable Credit Enhancement, follow
such collection procedures as it follows with respect to comparable loans held
in its own portfolio. Consistent with the above, the Servicer may, in its
discretion, (i) waive any assumption fee, late payment charge, or other charge
in connection with a Mortgage Loan and (ii) to the extent provided in the
related HELOC agreement, arrange with an obligor a schedule for the liquidation
of delinquencies by extending the Due Dates for Scheduled Payments on such
Mortgage Loan.

      If specified in the related Prospectus Supplement, the Servicer, to the
extent permitted by law, will establish and maintain escrow or impound accounts
("Escrow Accounts") with respect to Mortgage Loans in which payments by obligors
to pay taxes, assessments, mortgage and hazard insurance premiums, and other
comparable items will be deposited. Mortgage Loans may not require such payments
under the loan related documents, in which case the Servicer would not be
required to establish any Escrow Account with respect to such Mortgage Loans.
Withdrawals from the Escrow Accounts are to be made to effect timely payment of
taxes, assessments and mortgage and hazard insurance, to refund to obligors
amounts determined to be overages, to pay interest to obligors on balances in
the Escrow Account to the extent required by law, to repair or otherwise protect
the Mortgaged Property securing the related Mortgage Loan and to clear and
terminate such Escrow Account. The Servicer will be responsible for the
administration of the Escrow Accounts and generally will make advances to such
account when a deficiency exists therein. 

Deposits to and Withdrawals from the Collection Account

      Unless otherwise specified in the related Prospectus Supplement, the
Trustee or the Servicer will establish a separate account (the "Collection
Account") in the name of the Trustee. Unless otherwise indicated in the related
Prospectus Supplement, the Collection Account will be an account maintained (i)
at a depository institution, the unsecured debt obligations of which at the time
of any deposit therein are rated by each Rating Agency rating the Securities of
such Series at levels satisfactory to each Rating Agency or (ii) in an account
or accounts the deposits in which are insured to the maximum extent available by
the FDIC or which are secured in a manner meeting requirements established by
each Rating Agency.

      Unless otherwise specified in the related Prospectus Supplement, the funds
held in the Collection Account may be invested, pending remittance to the
Trustee, in Eligible Investments. If so specified in the related Prospectus
Supplement, the Servicer will be entitled to receive as additional compensation
any interest or other income earned on funds in the Collection Account.

      Unless otherwise specified in the related Prospectus Supplement, the
Servicer, the Depositor, the Trustee or the applicable Seller, as appropriate,
will deposit into the Collection Account for each Series on the Business Day
following the Closing Date any amounts representing Scheduled Payments due after
the related Cut-off Date but received by the Servicer on or before the Closing
Date, and thereafter, within two business days after the date of receipt
thereof, the following payments and collections received or made by it (other
than, unless otherwise provided in the related Prospectus Supplement, in respect
of principal of and interest on the related Mortgage Loans due on or before such
Cut-off Date):

            (i) All payments on account of principal, including prepayments, on
      such Mortgage Loans;

            (ii) All payments on account of interest on such Mortgage Loans
      after deducting therefrom, at the discretion of the Servicer but only to
      the extent of the amount permitted to be withdrawn or withheld 


                                       29
<PAGE>   108

      from the Collection Account in accordance with the related Agreement, the
      Servicing Fee in respect of such Mortgage Loans; 

            (iii) All amounts received by the Servicer in connection with the
      liquidation of Mortgage Loans or Mortgaged Property acquired in respect
      thereof, whether through foreclosure sale, repossession or otherwise,
      including payments in connection with such Mortgage Loans received from
      the obligor, other than amounts required to be paid or refunded to the
      obligor pursuant to the terms of the applicable loan documents or
      otherwise pursuant to law ("Liquidation Proceeds"), exclusive of, in the
      discretion of the Servicer, but only to the extent of the amount permitted
      to be withdrawn from the Collection Account in accordance with the related
      Agreement, the Servicing Fee, if any, in respect of the related Primary
      Asset;

            (iv) All proceeds under any title insurance, hazard insurance or
      other insurance policy covering any Mortgage Loan, other than proceeds to
      be applied to the restoration or repair of the related Mortgaged Property
      or released to the obligor in accordance with the related Agreement;

            (v) All amounts required to be deposited therein from any applicable
      Reserve Fund for such Series pursuant to the related Agreement;

            (vi) All Advances made by the Servicer required pursuant to the
      related Agreement; and 

            (vii) All repurchase prices of any such Mortgage Loans purchased or
      repurchased by the Depositor, the Servicer or the Seller pursuant to the
      related Agreement.

      Unless otherwise specified in the related Prospectus Supplement, the
Servicer is permitted, from time to time, to make withdrawals from the
Collection Account for each Series for the following purposes:

            (i) to reimburse itself for Advances for such Series made by it
      pursuant to the related Agreement; the Servicer's right to reimburse
      itself is limited to amounts received on or in respect of particular
      Mortgage Loans (including, for this purpose, Liquidation Proceeds and
      amounts representing proceeds of insurance policies covering the related
      Mortgaged Property) which represent late recoveries of Scheduled Payments
      respecting which any such Advance was made;

            (ii) to the extent provided in the related Agreement, to reimburse
      itself for any Advances for such Series that the Servicer determines in
      good faith it will be unable to recover from amounts representing late
      recoveries of Scheduled Payments respecting which such Advance was made or
      from Liquidation Proceeds or the proceeds of insurance policies;

            (iii) to reimburse itself from Liquidation Proceeds for liquidation
      expenses and for amounts expended by it in good faith in connection with
      the restoration of damaged Mortgaged Property and, in the event deposited
      in the Collection Account and not previously withheld, and to the extent
      that Liquidation Proceeds after such reimbursement exceed the outstanding
      principal balance of the related Mortgage Loan, together with accrued and
      unpaid interest thereon to the Due Date for such Mortgage Loan next
      succeeding the date of its receipt of such Liquidation Proceeds, to pay to
      itself out of such excess the amount of any unpaid Servicing Fee and any
      assumption fees, late payment charges, or other charges on the related
      Mortgage Loan;

            (iv) if it has elected not to pay itself the Servicing Fee out of
      the interest component of any Scheduled Payment, late payment or other
      recovery with respect to a particular Mortgage Loan prior to the deposit
      of such Scheduled Payment, late payment or recovery into the Collection
      Account, to pay to itself the Servicing Fee, as adjusted pursuant to the
      related Agreement, from any such Scheduled Payment, late payment or such
      other recovery, to the extent permitted by the related Agreement;

            (v) to reimburse itself for expenses incurred by and recoverable by
      or reimbursable to it pursuant to the related Agreement;

            (vi) to pay to the applicable person with respect to each Mortgage
      Loan or REO Mortgaged Property acquired in respect thereof that has been
      repurchased or removed from the Trust Fund by the Depositor, the Servicer
      or the Seller pursuant to the related Agreement, all amounts received
      thereon and not distributed as of the date on which the related repurchase
      price was determined;


                                       30
<PAGE>   109

            (vii) to make payments to the Trustee of such Series for deposit
      into the Distribution Account, if any, or for remittance to the Holders of
      such Series in the amounts and in the manner provided for in the related
      Agreement; and

            (viii) to clear and terminate the Collection Account pursuant to the
      related Agreement.

      In addition, if the Servicer deposits in the Collection Account for a
Series any amount not required to be deposited therein, it may, at any time,
withdraw such amount from such Collection Account. 

Advances and Limitations Thereon

      The related Prospectus Supplement will describe the circumstances, if any,
under which the Servicer will make Advances with respect to delinquent payments
on Mortgage Loans. If specified in the related Prospectus Supplement, the
Servicer will be obligated to make Advances, and such obligations may be limited
in amount, or may not be activated until a certain portion of a specified
Reserve Fund is depleted. Advances are intended to provide liquidity and, except
to the extent specified in the related Prospectus Supplement, not to guarantee
or insure against losses. Accordingly, any funds advanced are recoverable by the
Servicer out of amounts received on particular Mortgage Loans which represent
late recoveries of principal or interest, proceeds of insurance policies or
Liquidation Proceeds respecting which any such Advance was made. If an Advance
is made and subsequently determined to be nonrecoverable from late collections,
proceeds of insurance policies, or Liquidation Proceeds from the related
Mortgage Loan, the Servicer may be entitled to reimbursement from other funds in
the Collection Account or Distribution Account, as the case may be, or from a
specified Reserve Fund, as applicable, to the extent specified in the related
Prospectus Supplement. 

Maintenance of Insurance Policies and Other Servicing Procedures

      Standard Hazard Insurance; Flood Insurance. Except as otherwise specified
in the related Prospectus Supplement, the Servicer will be required to maintain
or to cause the obligor on each Mortgage Loan to maintain a standard hazard
insurance policy providing coverage of the standard form of fire insurance with
extended coverage for certain other hazards as is customary in the state in
which the related Mortgaged Property is located. The standard hazard insurance
policies will provide for coverage at least equal to the applicable state
standard form of fire insurance policy with extended coverage for Mortgaged
Property of the type securing the related Mortgage Loans. In general, the
standard form of fire and extended coverage policy will cover physical damage
to, or destruction of, the related Mortgaged Property caused by fire, lightning,
explosion, smoke, windstorm, hail, riot, strike and civil commotion, subject to
the conditions and exclusions particularized in each policy. Because the
standard hazard insurance policies relating to the Mortgage Loans will be
underwritten by different hazard insurers and will cover Properties located in
various states, such policies will not contain identical terms and conditions.
The basic terms, however, generally will be determined by state law and
generally will be similar. Most such policies typically will not cover any
physical damage resulting from war, revolution, governmental actions, floods and
other water-related causes, earth movement (including earthquakes, landslides,
and mudflows), nuclear reaction, wet or dry rot, vermin, rodents, insects or
domestic animals, theft and, in certain cases, vandalism. The foregoing list is
merely indicative of certain kinds of uninsured risks and is not intended to be
all inclusive. Uninsured risks not covered by a special hazard insurance policy
or other form of Credit Enhancement may adversely affect distributions to
Holders. When a Mortgaged Property securing a Mortgage Loan is located in a
flood area identified by HUD pursuant to the Flood Disaster Protection Act of
1973, as amended, the Servicer will be required to cause flood insurance to be
maintained with respect to such Mortgaged Property, to the extent available.

      The standard hazard insurance policies covering Properties securing
Mortgage Loans typically will contain a coinsurance clause which, in effect,
will require the insured at all times to carry hazard insurance of a specified
percentage (generally 80% to 90%) of the full replacement value of the Mortgaged
Property, including the improvements on any Mortgaged Property, in order to
recover the full amount of any partial loss. If the insured's coverage falls
below this specified percentage, such clause will provide that the hazard
insurer's liability in the event of partial loss will not exceed the greater of
(i) the actual cash value (the replacement cost less physical depreciation) of
the Mortgaged Property, including the improvements, if any, damaged or destroyed
or (ii) such proportion of the loss, without deduction for depreciation, as the
amount of insurance carried bears to the specified percentage of the full
replacement cost of such Mortgaged Property and improvements. Since the amount
of hazard insurance to be maintained on the improvements securing the Mortgage
Loans declines as the principal balances owing thereon decrease, and since the
value of the Properties will fluctuate in value over time, the effect of this
requirement in the


                                       31
<PAGE>   110

event of partial loss may be that hazard insurance proceeds will be insufficient
to restore fully the damage to the affected Mortgaged Property.

      Unless otherwise specified in the related Prospectus Supplement, coverage
will be in an amount at least equal to the greater of (i) the amount necessary
to avoid the enforcement of any co-insurance clause contained in the policy or
(ii) the outstanding principal balance of the related Mortgage Loan. Unless
otherwise specified in the related Prospectus Supplement, the Servicer will also
maintain on REO Mortgaged Property that secured a defaulted Mortgage Loan and
that has been acquired upon foreclosure, deed in lieu of foreclosure, or
repossession, a standard hazard insurance policy in an amount that is at least
equal to the maximum insurable value of such REO Mortgaged Property. No
earthquake or other additional insurance will be required of any obligor or will
be maintained on REO Mortgaged Property acquired in respect of a defaulted
Mortgage Loan, other than pursuant to such applicable laws and regulations as
shall at any time be in force and shall require such additional insurance.

      Any amounts collected by the Servicer under any such policies of insurance
(other than amounts to be applied to the restoration or repair of the Mortgaged
Property, released to the obligor in accordance with normal servicing procedures
or used to reimburse the Servicer for amounts to which it is entitled to
reimbursement) will be deposited in the Collection Account. In the event that
the Servicer obtains and maintains a blanket policy insuring against hazard
losses on all of the Mortgage Loans, written by an insurer then acceptable to
each Rating Agency which assigns a rating to such Series, it will conclusively
be deemed to have satisfied its obligations to cause to be maintained a standard
hazard insurance policy for each Mortgage Loan or related REO Mortgaged
Property. This blanket policy may contain a deductible clause, in which case the
Servicer will, in the event that there has been a loss that would have been
covered by such policy absent such deductible clause, deposit in the Collection
Account the amount not otherwise payable under the blanket policy because of the
application of such deductible clause. 

Realization Upon Defaulted Mortgage Loans

      The Servicer will use its reasonable best efforts to foreclose upon,
repossess or otherwise comparably convert the ownership of the Properties
securing the related Mortgage Loans as come into and continue in default and as
to which no satisfactory arrangements can be made for collection of delinquent
payments. In connection with such foreclosure or other conversion, the Servicer
will follow such practices and procedures as it deems necessary or advisable and
as are normal and usual in its servicing activities with respect to comparable
loans serviced by it. However, the Servicer will not be required to expend its
own funds in connection with any foreclosure or towards the restoration of any
Mortgaged Property unless it determines that: (i) such restoration or
foreclosure will increase the Liquidation Proceeds in respect of the related
Mortgage Loan available to the Holders after reimbursement to itself for such
expenses and (ii) such expenses will be recoverable by it either through
Liquidation Proceeds or the proceeds of insurance. While the holder of a
Mortgaged Property acquired through foreclosure can often maximize its recovery
by providing financing to a new purchaser, the Trust Fund, if applicable, will
have no ability to do so and neither the Servicer nor the Depositor will be
required to do so.

      The Servicer may arrange with the obligor on a defaulted Mortgage Loan, a
modification of such Mortgage Loan (a "Modification") to the extent provided in
the related Prospectus Supplement. Such Modifications may only be entered into
if they meet the underwriting policies and procedures employed by the Servicer
in servicing receivables for its own account and meet the other conditions set
forth in the related Prospectus Supplement. 

Enforcement of Due-On-Sale Clauses

      Unless otherwise specified in the related Prospectus Supplement for a
Series, when any Mortgaged Property is about to be conveyed by the obligor, the
Servicer will, to the extent it has knowledge of such prospective conveyance and
prior to the time of the consummation of such conveyance, exercise its rights to
accelerate the maturity of the related Mortgage Loan under the applicable
"due-on-sale" clause, if any, unless it reasonably believes that such clause is
not enforceable under applicable law or if the enforcement of such clause would
result in loss of coverage under any primary mortgage insurance policy. In such
event, the Servicer is authorized to accept from or enter into an assumption
agreement with the person to whom such Mortgaged Property has been or is about
to be conveyed, pursuant to which such person becomes liable under the Mortgage
Loan and pursuant to which the original obligor is released from liability and
such person is substituted as the obligor and becomes liable under the Mortgage
Loan. Any fee collected in connection with an assumption will be retained by the
Servicer as additional servicing compensation. The terms of a Mortgage Loan may
not be changed in connection with an assumption.


                                       32
<PAGE>   111

Servicing Compensation and Payment of Expenses

      Except as otherwise provided in the related Prospectus Supplement, the
Servicer will be entitled to a periodic fee as servicing compensation (the
"Servicing Fee") in an amount to be determined as specified in the related
Prospectus Supplement. The Servicing Fee may be fixed or variable, as specified
in the related Prospectus Supplement. In addition, unless otherwise specified in
the related Prospectus Supplement, the Servicer will be entitled to servicing
compensation in the form of assumption fees, late payment charges and similar
items, or excess proceeds following disposition of Mortgaged Property in
connection with defaulted Mortgage Loans.

      Unless otherwise specified in the related Prospectus Supplement, the
Servicer will pay certain expenses incurred in connection with the servicing of
the Mortgage Loans, including, without limitation, the payment of the fees and
expenses of the Trustee and independent accountants, payment of insurance policy
premiums and the cost of credit support, if any, and payment of expenses
incurred in preparation of reports to Holders.

      When an obligor makes a principal prepayment in full between Due Dates on
the related Mortgage Loan, the obligor will generally be required to pay
interest on the amount prepaid only to the date of prepayment. If and to the
extent provided in the related Prospectus Supplement, in order that one or more
Classes of the Holders of a Series will not be adversely affected by any
resulting shortfall in interest, the amount of the Servicing Fee may be reduced
to the extent necessary to include in the Servicer's remittance to the Trustee
for deposit into the Distribution Account an amount equal to one month's
interest on the related Mortgage Loan (less the Servicing Fee). If the aggregate
amount of such shortfalls in a month exceeds the Servicing Fee for such month, a
shortfall to Holders may occur.

      Unless otherwise specified in the related Prospectus Supplement, the
Servicer will be entitled to reimbursement for certain expenses incurred by it
in connection with the liquidation of defaulted Mortgage Loans. The related
Holders will suffer no loss by reason of such expenses to the extent expenses
are covered under related insurance policies or from excess Liquidation
Proceeds. If claims are either not made or paid under the applicable insurance
policies or if coverage thereunder has been exhausted, the related Holders will
suffer a loss to the extent that Liquidation Proceeds, after reimbursement of
the Servicer's expenses, are less than the outstanding principal balance of and
unpaid interest on the related Mortgage Loan which would be distributable to
Holders. In addition, the Servicer will be entitled to reimbursement of
expenditures incurred by it in connection with the restoration of Mortgaged
Property securing a defaulted Mortgage Loan, such right of reimbursement being
prior to the rights of the Holders to receive any related proceeds of insurance
policies, Liquidation Proceeds or amounts derived from other Credit Enhancement.
The Servicer is generally also entitled to reimbursement from the Collection
Account for Advances.

      Unless otherwise specified in the related Prospectus Supplement, the
rights of the Servicer to receive funds from the Collection Account for a
Series, whether as the Servicing Fee or other compensation, or for the
reimbursement of Advances, expenses or otherwise, are not subordinate to the
rights of Holders of such Series. 

Evidence as to Compliance

      If so specified in the related Prospectus Supplement, the applicable
Agreement for each Series will provide that each year a firm of independent
public accountants will furnish a statement to the Trustee to the effect that
such firm has examined certain documents and records relating to the servicing
of the Mortgage Loans by the Servicer and that, on the basis of such
examination, such firm is of the opinion that the servicing has been conducted
in compliance with such Agreement, except for (i) such exceptions as such firm
believes to be immaterial and (ii) such other exceptions as are set forth in
such statement.

      If so specified in the related Prospectus Supplement, the applicable
Agreement for each Series will also provide for delivery to the Trustee for such
Series of an annual statement signed by an officer of the Servicer to the effect
that the Servicer has fulfilled its obligations under such Agreement, throughout
the preceding calendar year. 

Certain Matters Regarding the Servicer

      The Agreement provides that the Servicer may resign from its obligations
and duties thereunder, except in connection with a permitted transfer of
servicing, unless (i) such duties and obligations are no longer permissible
under applicable law or are in material conflict by reason of applicable law
with any other activities of a type and nature presently carried on by it or its
affiliate or (ii) upon the satisfaction of the following conditions: (a) the
Servicer has proposed a successor servicer to the Trustee in writing and such
proposed successor servicer is 


                                       33
<PAGE>   112

reasonably acceptable to the Trustee; (b) the Rating Agencies have confirmed to
the Trustee that the appointment of such proposed successor servicer as the
Servicer will not result in the reduction or withdrawal of the then current
rating of the Certificates; and (c) such proposed successor servicer is
reasonably acceptable to the Enhancer, if any. No such resignation will become
effective until the Trustee or a successor servicer has assumed the Servicer's
obligations and duties under the Agreement. Notwithstanding the foregoing, Bank
One may transfer its servicing obligations to any other direct or indirect
wholly-owned subsidiary of BANC ONE or another entity (which meets certain
eligibility standards set forth in the Agreement) and be relieved of its
obligations and duties under the Agreement and related agreements.

      The Servicer may perform any of its duties and obligations under the
Agreement through one or more subservicers or delegates, which may be affiliates
of the Servicer. Notwithstanding any such arrangement, the Servicer will remain
liable and obligated to the Trustee and the Certificateholders for the
Servicer's duties and obligations under the Agreement, without any diminution of
such duties and obligations and as if the Servicer itself were performing such
duties and obligations.

      Any person into which, in accordance with the Agreement, the Servicer may
be merged or consolidated or any person resulting from any merger or
consolidation to which the Servicer is a party, or any person succeeding to the
business of the Servicer, will be the successor to Bank One as servicer, under
the Agreement.

      The Agreement provides that the Servicer will indemnify the Trust and the
Trustee from and against any loss, liability, expense, damage or injury suffered
or sustained as a result of the Servicer's actions or omissions in connection
with the servicing and administration of the Mortgage Loans which are not in
accordance with the provisions of the Agreement. Under the Agreement, the
applicable Seller will indemnify an injured party for the entire amount of any
losses, claims, damages or liabilities arising out of or based on the Agreement
(other than losses resulting from defaults under the Mortgage Loans). The
Agreement provides that neither the Depositor, any Seller nor the Servicer nor
their directors, officers, employees or agents will be under any other liability
to the Trust, the Trustee, the Certificateholders or any other person for any
action taken or for refraining from taking any action pursuant to the Agreement.
However, neither the Depositor, any Seller nor the Servicer will be protected
against any liability which would otherwise be imposed by reason of willful
misconduct, bad faith or gross negligence of the Depositor, such Seller or the
Servicer in the performance of its duties under the Agreement or by reason of
reckless disregard of its obligations thereunder. In addition, the Agreement
provides that the Servicer will not be under any obligation to appear in,
prosecute or defend any legal action which is not incidental to its servicing
responsibilities under the Agreement and which in its opinion may expose it to
any expense or liability. The Servicer may, in its sole discretion, undertake
any such legal action which it may deem necessary or desirable with respect to
the Agreement and the rights and duties of the parties thereto and the interest
of the Certificateholders thereunder.

      Any corporation into which the Servicer may be merged or consolidated, or
any corporation resulting from any merger, conversion or consolidation to which
the Servicer shall be a party, or any corporation succeeding to the business of
the Servicer shall be the successor of the Servicer hereunder, without the
execution or filing of any paper or any further act on the part of any of the
parties. 

Events of Servicing Termination

      Unless otherwise specified in the related Prospectus Supplement, "Events
of Servicing Termination" with respect to a Series will consist of (i) any
failure by the Servicer to deposit in the Collection Account any deposit
required to be made under the Agreement, which failure continues unremedied for
five Business Days after the giving of written notice of such failure to the
Servicer by the Trustee, or to the Servicer and the Trustee by the Enhancer, if
any, or Holders owning in the aggregate at least 25% of the Principal Balance of
all outstanding Securities; (ii) any failure by the Servicer duly to observe or
perform in any material respect any other of its covenants or agreements in the
Agreement which, in each case, materially and adversely affects the interests of
the Holders or the Enhancer, if any, and continues unremedied for 60 days after
the giving of written notice of such failure to the Servicer by the Trustee, or
to the Servicer and the Trustee by the Enhancer, if any, or Holders owning in
the aggregate at least 25% of the Principal Balance of all outstanding
Securities; or (iii) certain events of insolvency, readjustment of debt,
marshaling of assets and liabilities or similar proceedings relating to the
Servicer and certain actions by the Servicer indicating insolvency,
reorganization or inability to pay its obligations. Under certain other
circumstances, the Enhancer, if any, with the consent of Holders owning in the
aggregate at least 51% of the Principal Balance of all outstanding Securities
may deliver written notice to the Servicer terminating all the rights and
obligations of the Servicer under the Agreement.


                                       34
<PAGE>   113

      Notwithstanding the foregoing, the Agreement provides that a delay in or
failure of performance referred to under clause (i) above for a period of ten
Business Days or referred to under clause (ii) above for a period of 60 Business
Days, will not constitute an Event of Servicing Termination if such delay or
failure could not be prevented by the exercise of reasonable diligence by the
Servicer or such delay or failure was caused by an act of God or other similar
occurrence. Under the Agreement, upon the occurrence of any such event, the
Servicer will not be relieved from using reasonable efforts to perform its
obligations in a timely manner in accordance with the terms of the Agreement and
the Servicer will provide the Trustee, the Depositor, the applicable Sellers,
any Enhancer and the Holders prompt notice of such failure or delay by it,
together with a description of its efforts to so perform its obligations.

Rights Upon an Event of Servicing Termination

      Unless otherwise specified in the related Prospectus Supplement, so long
as an Event of Servicing Termination remains unremedied, either the Trustee, or
Holders owning in the aggregate at least 51% of the Principal Balance of all
outstanding Securities or any Credit Enhancer, may terminate all of the rights
and obligations of the Servicer under the Agreement and in and to the Mortgage
Loans, whereupon the Trustee will succeed to all the responsibilities, duties
and liabilities of the Servicer under the Agreement and will be entitled to
similar compensation arrangements. If the Trustee would be obligated to succeed
the Servicer but is unwilling or unable so to act, it may appoint, or petition a
court of competent jurisdiction for the appointment of, a housing and home
finance institution or other mortgage loan or home equity servicer with all
licenses and permits required to perform its obligations under the Agreement and
having a net worth of at least $15,000,000 and acceptable to any Credit Enhancer
to act as successor to the Servicer under the Agreement. Pending such
appointment, the Trustee will be obligated to act in such capacity unless
prohibited by law. Such successor will be entitled to receive the same
compensation that the Servicer would otherwise have received (or such lesser
compensation as the Trustee and such successor may agree). A receiver or
conservator for the Servicer may be empowered to prevent the termination and
replacement of the Servicer where the only Event of Servicing Termination that
has occurred is an Insolvency Event.

                                 THE AGREEMENTS

      The following summaries describe certain provisions of the Agreements. The
summaries do not purport to be complete and are subject to, and qualified in
their entirety by reference to, the provisions of the Agreements. Where
particular provisions or terms used in the Agreements are referred to, such
provisions or terms are as specified in the related Agreements. 

Assignment of Mortgage Loans

      At the time of issuance of the Certificates, the Depositor will transfer
to the Trust all of its right, title and interest in and to each Mortgage Loan
(including any Additional Balances arising in the future), related Credit Line
Agreements, mortgages and other related documents (collectively, the "Related
Documents"), including all collections received on or with respect to each such
Mortgage Loan after the Cut-off Date (exclusive of payments in respect of
accrued interest due on or prior to the Cut-off Date). The Trustee, concurrently
with such transfer, will deliver the Securities to the Depositor and any
Transferor Certificate (as defined in the Agreement) to the related Seller or
Sellers. Each Mortgage Loan transferred to the Trust will be identified on a
schedule (the "Mortgage Loan Schedule") delivered to the Trustee pursuant to the
Agreement. Such schedule will include information as to the Cut-off Date
Principal Balance of each Mortgage Loan, as well as information with respect to
the Loan Rate.

      Unless otherwise specified in the related Prospectus Supplement, the
Agreement will permit the applicable Seller to maintain possession of the
Related Documents and certain other documents relating to the Mortgage Loans
(the "Mortgage Files") and assignments of the related mortgages to the Trustee
will not be required to be recorded for so long as the senior unsecured debt of
Bank One is rated at levels satisfactory to each Rating Agency rating the
related Securities. If such rating does not satisfy such standards (an
"Assignment Event"), Bank One will have 90 days to record assignments of the
mortgages for each such Mortgage Loan in favor of the Trustee and will have 60
days to deliver the Mortgage File pertaining to each such Mortgage Loan to the
Trustee (unless opinions of counsel satisfactory to the Rating Agencies and any
Enhancer to the effect that recordation of such assignments or delivery of such
documentation is not required in the relevant jurisdiction to protect the
interest of the Trustee in the Mortgage Loans). In lieu of delivery of original
documentation, Bank One may deliver documents which have been imaged optically
upon delivery of an opinion of counsel that (i) such documents do not impair the
enforceability of the transfer to the Trust of the Mortgage Loans and (ii) the
optical image of such documents are enforceable in the relevant jurisdictions to
the same extent as the original documents.

      Within 90 days of an Assignment Event, the Trustee will review the
Mortgage Files and if any Related Document is found to be defective in any
material respect and such defect is not cured within 90 days following
notification thereof to the applicable Seller and the Depositor by the Trustee,
the applicable Seller will be obligated to accept the transfer of such Mortgage
Loan from the Trust. Upon such transfer, the Principal Balance of such Mortgage
Loan will be deducted from the Pool Balance. If the related Series includes a
Transferor Interest, such deduction would reduce the Transferor Interest. If the
deduction would cause the Transferor Interest to become less than the Minimum
Transferor Interest at such time (a "Transfer Deficiency"), the Seller will be
obligated to either substitute an Eligible Substitute Mortgage Loan or make a
deposit into the Collection Account in the amount (the "Transfer Deposit
Amount") equal to the amount by which the Transferor Interest would be reduced
to less than the Minimum Transferor Interest at such time. Any such deduction,
substitution or deposit, will be considered for the purposes of the Agreement a
payment in full of such Mortgage Loan. Any Transfer Deposit Amount will be
treated as a Principal Collection. No such transfer shall be considered to have
occurred until the required deposit to the Collection Account is actually made.
The obligation of a Seller to accept a transfer of a Defective Mortgage Loan is
the sole remedy regarding any defects in the Mortgage File and Related Documents
available to the Trustee or the Certificateholders.

      Unless otherwise specified in the related Prospectus Supplement, an
"Eligible Substitute Mortgage Loan" is a mortgage loan substituted by the
Depositor for a Defective Mortgage Loan which must, on the date of such
substitution, (i) have an outstanding Principal Balance (or in the case of a
substitution of more than one Mortgage Loan for a Defective Mortgage Loan, an
aggregate principal Balance) that is approximately equal to the Transfer
Deficiency relating to such Defective Mortgage Loan: (ii) have a Loan Rate not
less than the Loan Rate of the Defective Mortgage Loan and not more than 1% in
excess of the Loan Rate of such Defective Mortgage Loan; (iii) have a Loan Rate
based on the same Index with adjustments to such Loan Rate made on the same
Interest Rate Adjustment Date as that of the Defective Mortgage Loan; (iv) have
a Margin that is not less than the Margin of the 


                                       36
<PAGE>   115

Defective Mortgage Loan and not more than 100 basis points higher than the
Margin for the Defective Mortgage Loan; (v) have a mortgage of the same or
higher level of priority as the mortgage relating to the Defective Mortgage
Loan; (vi) have a remaining term to maturity not more than six months earlier
and not more than 60 months later than the remaining term to maturity of the
Defective Mortgage Loan; (vii) comply with each representation and warranty as
to the Mortgage Loans set forth in the Agreement (deemed to be made as of the
date of substitution); (viii) in general, have an original Combined
Loan-to-Value Ratio not greater than that of the Defective Mortgage Loan; and
(ix) satisfy certain other conditions specified in the Agreement. To the extent
the Principal Balance of an Eligible Substitute Mortgage Loan is less than the
Principal Balance of the related Defective Mortgage Loan and to the extent that
the Transferor Interest, if any, would be reduced below the Minimum Transferor
Interest, the applicable Seller will be required to make a deposit to the
Collection Account equal to such difference.

      The applicable Seller will make certain representations and warranties as
to the accuracy in all material respects of certain information furnished to the
Trustee with respect to each Mortgage Loan. In addition, the applicable Seller
will represent and warrant on the Closing Date that at the time of transfer to
the Depositor, such Seller has transferred or assigned all of its rights, title
and interest in or granted a security interest in each Mortgage Loan sold by it
and the Related Documents, free of any lien (subject to certain exceptions).
Upon discovery of a breach of any such representation and warranty which
materially and adversely affects the interests of the Holders or any Credit
Enhancer in the related Mortgage Loan and Related Documents, the applicable
Seller will have a period of 90 days after discovery or notice of the breach to
effect a cure. If the breach cannot be cured within the 90-day period, such
Seller will be obligated to accept a transfer of the Defective Mortgage Loan
from the Trust. The same procedure and limitations that are set forth in the
second preceding paragraph for the transfer of Defective Mortgage Loans will
apply to the transfer of a Mortgage Loan that is required to be transferred
because of such breach of a representation or warranty in the Agreement that
materially and adversely affects the interests of the Certificateholders.

      Mortgage Loans required to be transferred to the Seller as described in
the preceding paragraphs are referred to as "Defective Mortgage Loans." 

Reports to Holders

      The Trustee or other entity specified in the related Prospectus Supplement
will prepare and forward to each Holder on each Distribution Date, or as soon
thereafter as is practicable, a statement setting forth, to the extent
applicable to any Series, among other things:

            (i) the amount of principal distributed to Holders of the related
      Securities and the outstanding principal balance of such Securities
      following such distribution;

            (ii) the amount of interest distributed to Holders of the related
      Securities and the current interest on such Securities;

            (iii) the amounts of (a) any overdue accrued interest included in
      such distribution, (b) any remaining overdue accrued interest with respect
      to such Securities or (c) any current shortfall in amounts to be
      distributed as accrued interest to holders of such Securities;

            (iv) the amounts of (a) any overdue payments of scheduled principal
      included in such distribution, (b) any remaining overdue principal amounts
      with respect to such Securities, (c) any current shortfall in receipt of
      scheduled principal payments on the related Mortgage Loans or (d) any
      realized losses or Liquidation Proceeds to be allocated as reductions in
      the outstanding principal balances of such Securities;

            (v) the amount received under any related Credit Enhancement, and
      the remaining amount available under such Credit Enhancement;

            (vi) the amount of any delinquencies with respect to payments on the
      related Mortgage Loans; 

            (vii) the book value of any REO Mortgaged Property acquired by the
      related Trust Fund; and 

            (viii) such other information as specified in the related Agreement.


                                       37
<PAGE>   116

      In addition, within a reasonable period of time after the end of each
calendar year the Trustee, unless otherwise specified in the related Prospectus
Supplement, will furnish to each Holder of record at any time during such
calendar year: (a) the aggregate of amounts reported pursuant to clauses (i),
(ii), and (iv)(d) above for such calendar year and (b) such information
specified in the related Agreement to enable Holders to prepare their tax
returns including, without limitation, the amount of original issue discount
accrued on the Securities, if applicable. Information in the Distribution Date
and annual statements provided to the Holders will not have been examined and
reported upon by an independent public accountant. However, the Servicer will
provide to the Trustee a report by independent public accountants with respect
to the Servicer's servicing of the Mortgage Loans. See "SERVICING OF
LOANS--Evidence as to Compliance". 

Events of Default; Rights Upon Event of Default

      Pooling and Servicing Agreement; Servicing Agreement. Unless otherwise
specified in the related Prospectus Supplement, Events of Default under the
Pooling and Servicing Agreement or Servicing Agreement for each Series of
Certificates are limited to the Events of Servicing Termination described under
"Servicing of the Mortgage Loans-Events of Servicing Termination."

      Indenture. Unless otherwise specified in the related Prospectus
Supplement, Events of Default under the Indenture for each Series of Notes
include: (i) a default for thirty (30) days or more in the payment of any
principal of or interest on any Note of such Series; (ii) failure to perform any
other covenant of the Depositor or the Trust Fund in the Indenture which
continues for a period of sixty (60) days after notice thereof is given in
accordance with the procedures described in the related Prospectus Supplement;
(iii) any representation or warranty made by the Depositor in the Indenture or
in any certificate or other writing delivered pursuant thereto or in connection
therewith with respect to or affecting such Series having been incorrect in a
material respect of the time made, and such breach is not cured within sixty
(60) days after notice thereof is given in accordance with the procedures
described in the related Prospectus Supplement; (iv) certain events of
bankruptcy, insolvency, receivership or liquidation of the Depositor or the
Trust Fund; or (v) any other Event of Default provided with respect to Notes of
that Series.

      If an Event of Default with respect to the Notes of any Series at the time
outstanding occurs and is continuing, either the Trustee or the holders of a
majority of the then aggregate outstanding amount of the Notes of such Series
may declare the principal amount (or, if the Notes of that Series are Zero
Coupon Securities, such portion of the principal amount as may be specified in
the terms of that Series, as provided in the related Prospectus Supplement) of
all the Notes of such Series to be due and payable immediately. Such declaration
may, under certain circumstances, be rescinded and annulled by the Holders of a
majority in aggregate outstanding amount of the Notes of such Series.

      If, following an Event of Default with respect to any Series of Notes, the
Notes of such Series have been declared to be due and payable, the Trustee may,
in its discretion, notwithstanding such acceleration, elect to maintain
possession of the collateral securing the Notes of such Series and to continue
to apply distributions on such collateral as if there had been no declaration of
acceleration if such collateral continues to provide sufficient funds for the
payment of principal of and interest on the Notes of such Series as they would
have become due if there had not been such a declaration. In addition, the
Trustee may not sell or otherwise liquidate the collateral securing the Notes of
a Series following an Event of Default, other than a default in the payment of
any principal or interest on any Note of such Series for thirty (30) days or
more, unless (a) the Holders of 100% of the then aggregate outstanding amount of
the Notes of such Series consent to such sale, (b) the proceeds of such sale or
liquidation are sufficient to pay in full the principal of and accrued interest,
due and unpaid, on the outstanding Notes of such Series at the date of such sale
or (c) the Trustee determines that such collateral would not be sufficient on an
ongoing basis to make all payments on such Notes as such payments would have
become due if such Notes had not been declared due and payable, and the Trustee
obtains the consent of the Holders of 66% of the then aggregate outstanding
amount of the Notes of such Series.

      In the event that the Trustee liquidates the collateral in connection with
an Event of Default involving a default for thirty (30) days or more in the
payment of principal of or interest on the Notes of a Series, the Indenture
provides that the Trustee will have a prior lien on the proceeds of any such
liquidation for unpaid fees and expenses. As a result, upon the occurrence of
such an Event of Default, the amount available for distribution to the
Noteholders would be less than would otherwise be the case. However, the Trustee
may not institute a proceeding for the enforcement of its lien except in
connection with a proceeding for the enforcement of the lien of the Indenture
for the benefit of the Noteholders after the occurrence of such an Event of
Default.

      Unless otherwise specified in the related Prospectus Supplement, in the
event the principal of the Notes of a Series is declared due and payable, as
described above, the holders of any such Notes issued at a discount from par may
be entitled to receive no more than an amount equal to the unpaid principal
amount thereof less the amount of such discount which is unamortized.

      Subject to the provisions of the Indenture relating to the duties of the
Trustee, in case an Event of Default shall occur and be continuing with respect
to a Series of Notes, the Trustee shall be under no obligation to exercise any
of the rights or powers under the Indenture at the request or direction of any
of the Holders of Notes of such Series, unless such Holders offered to the
Trustee security or indemnity satisfactory to it against the costs, expenses and
liabilities which might be incurred by it in complying with such request or
direction. Subject to such provisions for indemnification and certain
limitations contained in the Indenture, the Holders of a majority of the then
aggregate outstanding amount of the Notes of such Series shall have the right to
direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee or exercising any trust or power conferred on the
Trustee with respect to the Notes of such Series, and the Holders of a majority
of the then aggregate outstanding amount of the Notes of such Series may, in
certain cases, waive any default with respect thereto, except a default in the
payment of principal or interest or a default in respect of a covenant or
provision of the Indenture that cannot be modified without the waiver or consent
of all the Holders of the outstanding Notes of such Series affected thereby. 

The Trustee

      The identity of the commercial bank, savings and loan association or trust
company named as the Trustee for each Series of Securities will be set forth in
the related Prospectus Supplement. The entity serving as Trustee may have normal
banking relationships with the Depositor or the Servicer. In addition, for the
purpose of meeting the legal requirements of certain local jurisdictions, the
Trustee will have the power to appoint co-trustees or separate trustees of all
or any part of the Trust Fund relating to a Series of Securities. In the event
of such appointment, all rights, powers, duties and obligations conferred or
imposed upon the Trustee by the Agreement relating to such Series will be
conferred or imposed upon the Trustee and each such separate trustee or
co-trustee jointly, or, in any jurisdiction in which the Trustee shall be
incompetent or unqualified to perform certain acts, singly upon such separate
trustee or co-trustee who shall exercise and perform such rights, powers, duties
and obligations solely at the direction of the Trustee. The Trustee may also
appoint agents to perform any of the responsibilities of the Trustee, which
agents shall have any or all of the rights, powers, duties and obligations of
the Trustee conferred on them by such appointment; provided that the Trustee
shall continue to be responsible for its duties and obligations under the
Agreement. 

Duties of the Trustee

      The Trustee will make no representations as to the validity or sufficiency
of the Agreement, the Securities or of any Mortgage Loan or related documents.
If no Event of Default (as defined in the related Agreement) has occurred, the
Trustee is required to perform only those duties specifically required of it
under the Agreement. Upon receipt of the various certificates, statements,
reports or other instruments required to be furnished to it, the Trustee is
required to examine them to determine whether they are in the form required by
the related Agreement; however, the Trustee will not be responsible for the
accuracy or content of any such documents furnished by it or the Holders to the
Servicer under the Agreement.

      The Trustee may be held liable for its own negligent action or failure to
act, or for its own misconduct; provided, however, that the Trustee will not be
personally liable with respect to any action taken, suffered or omitted to be
taken by it in good faith in accordance with the direction of the Holders in an
Event of Default. The Trustee is not required to expend or risk its own funds or
otherwise incur any financial liability in the performance of any of its duties
under the Agreement, or in the exercise of any of its rights or powers, if it
has reasonable grounds for believing that repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it.

Resignation of Trustee

      The Trustee may, upon written notice to the Depositor, resign at any time,
in which event the Depositor will be obligated to use its best efforts to
appoint a successor Trustee. If no successor Trustee has been appointed and has
accepted the appointment within 30 days after giving such notice of resignation,
the resigning Trustee may petition any court of competent jurisdiction for
appointment of a successor Trustee. The Trustee may also be 


                                       39
<PAGE>   118

removed at any time (i) if the Trustee ceases to be eligible to continue as such
under the Agreement, (ii) if the Trustee becomes insolvent or (iii) by the
Holders of Securities evidencing over 50% of the aggregate voting rights of the
Securities in the Trust Fund upon written notice to the Trustee and to the
Depositor. Any resignation or removal of the Trustee and appointment of a
successor Trustee will not become effective until acceptance of the appointment
by the successor Trustee. 

Amendment of Agreement

      Unless otherwise specified in the Prospectus Supplement, the Agreement for
each Series of Securities may be amended by the Depositor, the Servicer (with
respect to a Series relating to Mortgage Loans), and the Trustee with respect to
such Series, without notice to or consent of the Holders (i) to cure any
ambiguity, (ii) to correct any defective provisions or to correct or supplement
any provision therein, (iii) to add to the duties of the Depositor, the Trust
Fund or Servicer, (iv) to add any other provisions with respect to matters or
questions arising under such Agreement or related Credit Enhancement, (v) to add
or amend any provisions of such Agreement as required by a Rating Agency in
order to maintain or improve the rating of the Securities, or (vi) to comply
with any requirements imposed by the Code; provided that any such amendment
except pursuant to clause (vi) above will not adversely affect in any material
respect the interests of any Holders of such Series, as evidenced by an opinion
of counsel. Any such amendment except pursuant to clause (vi) of the preceding
sentence shall be deemed not to adversely affect in any material respect the
interests of any Holder if the Trustee receives written confirmation from each
Rating Agency rating such Securities that such amendment will not cause such
Rating Agency to reduce the then current rating of each Class thereof. Unless
otherwise specified in the Prospectus Supplement, the Agreement for each Series
may also be amended by the Trustee, the Servicer, if applicable, and the
Depositor with respect to such Series with the consent of the Holders possessing
not less than 662/3% of the aggregate outstanding principal amount of the
Securities of such Series or, if only certain Classes of such Series are
affected by such amendment, 662/3% of the aggregate outstanding principal amount
of the Securities of each Class of such Series affected thereby, for the purpose
of adding any provisions to or changing in any manner or eliminating any of the
provisions of such Agreement or modifying in any manner the rights of Holders of
such Series; provided, however, that no such amendment may (a) reduce the amount
or delay the timing of payments on any Security without the consent of the
Holder of such Security; or (b) reduce the aforesaid percentage of the aggregate
outstanding principal amount of Securities of each Class, the Holders of which
are required to consent to any such amendment without the consent of the Holders
of 100% of the aggregate outstanding principal amount of each Class of
Securities affected thereby. 

Voting Rights

      The related Prospectus Supplement will set forth the method of determining
allocation of voting rights with respect to a Series.

List of Holders

      Upon written request of three or more Holders of record of a Series for
purposes of communicating with other Holders with respect to their rights under
the Agreement, which request is accompanied by a copy of the communication which
such Holders propose to transmit, the Trustee will afford such Holders access
during business hours to the most recent list of Holders of that Series held by
the Trustee.

      No Agreement will provide for the holding of any annual or other meeting
of Holders.

Termination

      Pooling and Servicing Agreement; Trust Agreement. The obligations created
by the Pooling and Servicing Agreement or Trust Agreement for a Series will
terminate upon the distribution to Holders of all amounts distributable to them
pursuant to such Agreement after the earlier of (i) the later of (a) the final
payment or other liquidation of the last Mortgage Loan remaining in the Trust
Fund for such Series and (b) the disposition of all Mortgaged Property acquired
upon foreclosure or deed in lieu of foreclosure or repossession in respect of
any Mortgage Loan or (ii) the repurchase, as described below, by the Servicer or
other entity specified in the related Prospectus Supplement from the Trustee for
such Series of all Mortgage Loans and other Mortgaged Property at that time
subject to such Agreement. The Agreement for each Series permits, but does not
require, the Servicer or other entity specified in the related Prospectus
Supplement to purchase from the Trust Fund for such Series all remaining
Mortgage Loans at a price equal to, unless otherwise specified in the related
Prospectus Supplement, 100% of the


                                       40
<PAGE>   119

aggregate Principal Balance of such Mortgage Loans plus, with respect to any
Mortgaged Property acquired in respect of a Mortgage Loan, if any, the
outstanding Principal Balance of the related Mortgage Loan at the time of
foreclosure, less, in either case, related unreimbursed Advances (in the case of
the Mortgage Loans, only to the extent not already reflected in the computation
of the aggregate Principal Balance of such Mortgage Loans) and unreimbursed
expenses (that are reimbursable pursuant to the terms of the Pooling and
Servicing Agreement) plus, in either case, accrued interest thereon at the
weighted average rate on the related Mortgage Loans through the last day of the
Due Period in which such repurchase occurs. The exercise of such right will
effect early retirement of the Securities of such Series, but such entity's
right to so purchase is subject to the aggregate Principal Balance of the
Mortgage Loans at the time of repurchase being less than a fixed percentage, to
be set forth in the related Prospectus Supplement, of the aggregate Principal
Balance of the Mortgage Loans as of the Cut-off Date. In no event, however, will
the trust created by the Agreement continue beyond the expiration of 21 years
from the death of the last survivor of certain persons identified therein. For
each Series, the Servicer or the Trustee, as applicable, will give written
notice of termination of the Agreement to each Holder, and the final
distribution will be made only upon surrender and cancellation of the Securities
at an office or agency specified in the notice of termination. If so provided in
the related Prospectus Supplement for a Series, the Depositor or another entity
may effect an optional termination of the Trust Fund under the circumstances
described in such Prospectus Supplement. See "DESCRIPTION OF THE
SECURITIES--Optional Purchase or Termination".

      Indenture. The Indenture will be discharged with respect to a Series of
Notes (except with respect to certain continuing rights specified in the
Indenture) upon the delivery to the Trustee for cancellation of all the Notes of
such Series or, with certain limitations, upon deposit with the Trustee of funds
sufficient for the payment in full of all of the Notes of such Series.

      In addition to such discharge with certain limitations, the Indenture will
provide that, if so specified with respect to the Notes of any Series, the
related Trust Fund will be discharged from any and all obligations in respect of
the Notes of such Series (except for certain obligations relating to temporary
Notes and exchange of Notes, to register the transfer of or exchange Notes of
such Series, to replace stolen, lost or mutilated Notes of such Series, to
maintain paying agencies and to-hold monies for payment in trust) upon the
deposit with the Trustee, in trust, of money and/or direct obligations of or
obligations guaranteed by the United States of America which through the payment
of interest and principal in respect thereof in accordance with their terms will
provide money in an amount sufficient to pay the principal of and each
installment of interest on the Notes of such Series on the Last Scheduled
Distribution Date for such Notes and any installment of interest on such Notes
in accordance with the terms of the Indenture and the Notes of such Series. In
the event of any such defeasance and discharge of Notes of such Series, holders
of Notes of such Series would be able to look only to such money and/or direct
obligations for payment of principal and interest, if any, on their Notes until
maturity.

                    CERTAIN LEGAL ASPECTS OF MORTGAGE LOANS

      The following discussion contains summaries of certain legal aspects of
mortgage loans which are general in nature. Because certain of such legal
aspects are governed by applicable state law (which laws may differ
substantially), the summaries do not purport to be complete nor reflect the laws
of any particular state, nor encompass the laws of all states in which the
properties securing the Mortgage Loans are situated. The summaries are qualified
in their entirety by reference to the applicable federal and state laws
governing the Mortgage Loans. 

Mortgages

      The Mortgage Loans for a Series will be secured by either mortgages or
deeds of trust or deeds to secure debt, depending upon the prevailing practice
in the state in which the Mortgaged Property subject to a mortgage loan is
located. The filing of a mortgage, deed of trust or deed to secure debt creates
a lien or title interest upon the real Mortgaged Property covered by such
instrument and represents the security for the repayment of an obligation that
is customarily evidenced by a promissory note. It is not prior to the lien for
real estate taxes and assessments or other charges imposed under governmental
police powers and may also be subject to other liens pursuant to the laws of the
jurisdiction in which the Mortgaged Property is located. Priority with respect
to such instruments depends on their terms, the knowledge of the parties to the
mortgage and generally on the order of recording with the applicable state,
county or municipal office. There are two parties to a mortgage, the mortgagor,
who is the borrower/Mortgaged Property owner or the land trustee (as described
below), and the mortgagee, who is the lender. Under the mortgage instrument, the
mortgagor delivers to the mortgagee a note or bond and the mortgage. In the case
of a land trust, there are three parties because title to the Mortgaged Property
is held by a land trustee under a land trust agreement of which the
borrower/Mortgaged Property owner is the beneficiary; at origination of a
mortgage loan, the borrower executes a separate undertaking to make payments on
the mortgage note. A deed of trust transaction normally has three parties, the
trustor, who is the borrower/Mortgaged Property owner; the beneficiary, who is
the lender, and the trustee, a third-party grantee. Under a deed of trust, the
trustor grants the Mortgaged Property, irrevocably until the debt is paid, in
trust, generally with a power of sale, to the trustee to secure payment of the
obligation. The mortgagee's authority under a mortgage and the trustee's
authority under a deed of trust are governed by the law of the state in which
the real Mortgaged Property is located, the express provisions of the mortgage
or deed of trust, and, in some cases, in deed of trust transactions, the
directions of the beneficiary. 

Foreclosure on Mortgages

      Foreclosure of a mortgage is generally accomplished by judicial action.
Generally, the action is initiated by the service of legal pleadings upon all
parties having an interest of record in the real Mortgaged Property. Delays in
completion of the foreclosure occasionally may result from difficulties in
locating necessary parties defendant. When the mortgagee's right to foreclosure
is contested, the legal proceedings necessary to resolve the issue can be
time-consuming and expensive. After the completion of a judicial foreclosure
proceeding, the court may issue a judgment of foreclosure and appoint a receiver
or other officer to conduct the sale of the Mortgaged Property. In some states,
mortgages may also be foreclosed by advertisement, pursuant to a power of sale
provided in the mortgage. Foreclosure of a mortgage by advertisement is
essentially similar to foreclosure of a deed of trust by non-judicial power of
sale.

      Foreclosure of a deed of trust is generally accomplished by a non-judicial
trustee's sale under a specific provision in the deed of trust which authorizes
the trustee to sell the Mortgaged Property upon any default by the borrower
under the terms of the note or deed of trust. In certain states, such
foreclosure also may be accomplished by judicial action in the manner provided
for foreclosure of mortgages. In some states, the trustee must record a notice
of default and send a copy to the borrower-trustor and to any person who has
recorded a request for a copy of the notice of sale. In addition, the trustee in
some states must provide notice of default to any other individual having an
interest in the real Mortgaged Property, including any junior lienholders. If
the deed of trust is not reinstated within any applicable cure period, a notice
of sale must be posted in a public place and, in most states, published for a
specified period of time in one or more newspapers. In addition, some state laws
require that a copy of the notice of sale be posted on the Mortgaged Property
and sent to all parties having an interest of record in the Mortgaged Property.
The trustor, borrower, or any person having a junior encumbrance on the real
estate, may, during a reinstatement period, cure the default by paying the
entire amount in arrears plus costs and expenses incurred in enforcing the
obligation. Generally, state law controls the amount of foreclosure expenses and
costs, 


                                       42
<PAGE>   121

including attorney's fees, which may be recovered by a lender. If the deed of
trust is not reinstated, a notice of sale must be posted in a public place and,
in most states, published for a specified period of time in one or more
newspapers. In addition, some state laws require that a copy of the notice of
sale be posted on the Mortgaged Property, recorded and sent to all parties
having an interest in the real Mortgaged Property.

      An action to foreclose a mortgage is an action to recover the mortgage
debt by enforcing the mortgagee's rights under the mortgage. It is regulated by
statutes and rules and subject throughout to the court's equitable powers.
Generally, a mortgagor is bound by the terms of the related mortgage note and
the mortgage as made and cannot be relieved from his default if the mortgagee
has exercised his rights in a commercially reasonable manner. However, since a
foreclosure action historically was equitable in nature, the court may exercise
equitable powers to relieve a mortgagor of a default and deny the mortgagee
foreclosure on proof that either the mortgagor's default was neither willful nor
in bad faith or the mortgagee's action established a waiver, fraud, bad faith,
or oppressive or unconscionable conduct such as to warrant a court of equity to
refuse affirmative relief to the mortgagee. Under certain circumstances a court
of equity may relieve the mortgagor from an entirely technical default where
such default was not willful.

      A foreclosure action is subject to most of the delays and expenses of
other lawsuits if defenses or counterclaims are interposed, sometimes requiring
up to several years to complete. Moreover, a non-collusive, regularly conducted
foreclosure sale may be challenged as a fraudulent conveyance, regardless of the
parties' intent, if a court determines that the sale was for less than fair
consideration and such sale occurred while the mortgagor was insolvent and
within one year (or within the state statute of limitations if the trustee in
bankruptcy elects to proceed under state fraudulent conveyance law) of the
filing of bankruptcy. Similarly, a suit against the debtor on the related
mortgage note may take several years and, generally, is a remedy alternative to
foreclosure, the mortgagee being precluded from pursuing both at the same time.

      In the case of foreclosure under either a mortgage or a deed of trust, the
sale by the referee or other designated officer or by the trustee is a public
sale. However, because of the difficulty potential third party purchasers at the
sale have in determining the exact status of title and because the physical
condition of the Mortgaged Property may have deteriorated during the foreclosure
proceedings, it is uncommon for a third party to purchase the Mortgaged Property
at a foreclosure sale. Rather, it is common for the lender to purchase the
Mortgaged Property from the trustee or referee for an amount which may be equal
to the unpaid principal amount of the mortgage note secured by the mortgage or
deed of trust plus accrued and unpaid interest and the expenses of foreclosure,
in which event the mortgagor's debt will be extinguished or the lender may
purchase for a lesser amount in order to preserve its right against a borrower
to seek a deficiency judgment in states where such a judgment is available.
Thereafter, subject to the right of the borrower in some states to remain in
possession during the redemption period, the lender will assume the burdens of
ownership, including obtaining hazard insurance, paying taxes and making such
repairs at its own expense as are necessary to render the Mortgaged Property
suitable for sale. The lender will commonly obtain the services of a real estate
broker and pay the broker's commission in connection with the sale of the
Mortgaged Property. Depending upon market conditions, the ultimate proceeds of
the sale of the Mortgaged Property may not equal the lender's investment in the
Mortgaged Property. Any loss may be reduced by the receipt of any mortgage
guaranty insurance proceeds. 

Rights of Redemption

      In some states, after sale pursuant to a deed of trust or foreclosure of a
mortgage, the trustor or mortgagor and foreclosed junior lienors are given a
statutory period in which to redeem the Mortgaged Property from the foreclosure
sale. The right of redemption should be distinguished from the equity of
redemption, which is a non-statutory right that must be exercised prior to the
foreclosure sale. In some states, redemption may occur only upon payment of the
entire principal balance of the loan, accrued interest and expenses of
foreclosure. In other states, redemption may be authorized if the former
borrower pays only a portion of the sums due. The effect of a statutory right of
redemption is to diminish the ability of the lender to sell the foreclosed
Mortgaged Property. The exercise of a right of redemption would defeat the title
of any purchaser at a foreclosure sale, or of any purchaser from the lender
subsequent to foreclosure or sale under a deed of trust. Consequently, the
practical effect of a right of redemption is to force the lender to retain the
Mortgaged Property and pay the expenses of ownership until the redemption period
has run. In some states, there is no right to redeem Mortgaged Property after a
trustee's sale under a deed of trust.


                                       43
<PAGE>   122

Junior Mortgages; Rights of Senior Mortgages

      The mortgage loans included in the Trust Fund for a Series will be secured
by mortgages or deeds of trust which may be second or more junior mortgages to
other mortgages held by other lenders or institutional investors. The rights of
the Trust Fund (and therefore the Holders), as mortgagee under a junior
mortgage, are subordinate to those of the mortgagee under the senior mortgage,
including the prior rights of the senior mortgagee to receive hazard insurance
and condemnation proceeds and to cause the Mortgaged Property securing the
mortgage loan to be sold upon default of the mortgagor, thereby extinguishing
the junior mortgagee's lien unless the junior mortgagee asserts its subordinate
interest in the Mortgaged Property in foreclosure litigation and, possibly,
satisfies the defaulted senior mortgage. A junior mortgagee may satisfy a
defaulted senior loan in full and, in some states, may cure such default and
bring the senior loan current, in either event adding the amounts expended to
the balance due on the junior loan. In most states, absent a provision in the
mortgage or deed of trust, no notice of default is required to be given to a
junior mortgagee.

      The standard form of the mortgage used by most institutional lenders
confers on the mortgagee the right both to receive all proceeds collected under
any hazard insurance policy and all awards made in connection with condemnation
proceedings, and to apply such proceeds and awards to any indebtedness secured
by the mortgage, in such order as the mortgagee may determine. Thus, in the
event improvements on the Mortgaged Property are damaged or destroyed by fire or
other casualty, or in the event the Mortgaged Property is taken by condemnation,
the mortgagee or beneficiary under underlying senior mortgages will have the
prior right to collect any insurance proceeds payable under a hazard insurance
policy and any award of damages in connection with the condemnation and to apply
the same to the indebtedness secured by the senior mortgages. Proceeds in excess
of the amount of senior mortgage indebtedness, in most cases, may be applied to
the indebtedness of a junior mortgage.

      Another provision sometimes found in the form of the mortgage or deed of
trust used by institutional lenders obligates the mortgagor to pay before
delinquency all taxes and assessments on the Mortgaged Property and, when due,
all encumbrances, charges and liens on the Mortgaged Property which appear prior
to the mortgage or deed of trust, to provide and maintain fire insurance on the
Mortgaged Property, to maintain and repair the Mortgaged Property and not to
commit or permit any waste thereof, and to appear in and defend any action or
proceeding purporting to affect the Mortgaged Property or the rights of the
mortgagee under the mortgage. Upon a failure of the mortgagor to perform any of
these obligations, the mortgagee is given the right under certain mortgages to
perform the obligation itself, at its election, with the mortgagor agreeing to
reimburse the mortgagee for any sums expended by the mortgagee on behalf of the
mortgagor. All sums so expended by the mortgagee become part of the indebtedness
secured by the mortgage.

      The form of credit line trust deed or mortgage used by most institutional
lenders which make revolving home equity loans typically contains a "future
advance" clause, which provides, in essence, that additional amounts advanced to
or on behalf of the borrower by the beneficiary or lender are to be secured by
the deed of trust or mortgage. The priority of the lien securing any advance
made under the clause may depend in most states on whether the deed of trust or
mortgage is called and recorded as a credit line deed of trust or mortgage. If
the beneficiary or lender advances additional amounts, the advance is entitled
to receive the same priority as amounts initially advanced under the trust deed
or mortgage, notwithstanding the fact that there may be junior trust deeds or
mortgages and other liens which intervene between the date of recording of the
trust deed or mortgage and the date of the future advance, and notwithstanding
that the beneficiary or lender had actual knowledge of such intervening junior
trust deeds or mortgages and other liens at the time of the advance. In most
states, the trust deed or mortgage lien securing mortgage loans of the type
which includes revolving home equity credit lines applies retroactively to the
date of the original recording of the trust deed or mortgage, provided that the
total amount of advances under the home equity credit line does not exceed the
maximum specified principal amount of the recorded trust deed or mortgage,
except as to advances made after receipt by the lender of a written notice of
lien from a judgment lien creditor of the trustor.

Anti-Deficiency Legislation and Other Limitations on Lenders

      Certain states have imposed statutory prohibitions which limit the
remedies of a beneficiary under a deed of trust or a mortgagee under a mortgage.
In some states, statutes limit the right of the beneficiary or mortgagee to
obtain a deficiency judgment against the borrower following foreclosure or sale
under a deed of trust. A deficiency judgment is a personal judgment against the
former borrower equal in most cases to the difference between the net amount
realized upon the public sale of the real Mortgaged Property and the amount due
to the lender. Other 


                                       44
<PAGE>   123

statutes require the beneficiary or mortgagee to exhaust the security afforded
under a deed of trust or mortgage by foreclosure in an attempt to satisfy the
full debt before bringing a personal action against the borrower. In certain
other states, the lender has the option of bringing a personal action against
the borrower on the debt without first exhausting such security; however, in
some of these states, the lender, following judgment on such personal action,
may be deemed to have elected a remedy and may be precluded from exercising
remedies with respect to the security. Consequently, the practical effect of the
election requirement, when applicable, is that lenders will usually proceed
first against the security rather than bringing a personal action against the
borrower. Finally, other statutory provisions limit any deficiency judgment
against the former borrower following a foreclosure sale to the excess of the
outstanding debt over the fair market value of the Mortgaged Property at the
time of the public sale. The purpose of these statutes is generally to prevent a
beneficiary or a mortgagee from obtaining a large deficiency judgment against
the former borrower as a result of low or no bids at the foreclosure sale.

      In addition to laws limiting or prohibiting deficiency judgments, numerous
other statutory provisions, including the federal bankruptcy laws, the Federal
Soldiers' and Sailors' Civil Relief Act, and state laws affording relief to
debtors, may interfere with or affect the ability of the secured lender to
realize upon collateral and/or enforce a deficiency judgment. For example, with
respect to federal bankruptcy law, the filing of a petition acts as a stay
against the enforcement of remedies for collection of a debt. Moreover, a court
with federal bankruptcy jurisdiction may permit a debtor through a Chapter 13
Bankruptcy Code rehabilitative plan to cure a monetary default with respect to a
loan on a debtor's residence by paying arrearages within a reasonable time
period and reinstating the original loan payment schedule even though the lender
accelerated the loan and the lender has taken all steps to realize upon his
security (provided no sale of the Mortgaged Property has yet occurred) prior to
the filing of the debtor's Chapter 13 petition. Some courts with federal
bankruptcy jurisdiction have approved plans, based on the particular facts of
the reorganization case, that effected the curing of a loan default by
permitting the obligor to pay arrearages over a number of years.

      Courts with federal bankruptcy jurisdiction have also indicated that the
terms of a mortgage loan may be modified if the borrower has filed a petition
under Chapter 13. These courts have suggested that such modifications may
include reducing the amount of each monthly payment, changing the rate of
interest, altering the repayment schedule and reducing the lender's security
interest to the value of the residence, thus leaving the lender a general
unsecured creditor for the difference between the value of the residence and the
outstanding balance of the loan. Federal bankruptcy law and limited case law
indicate that the foregoing modifications could not be applied to the terms of a
loan secured by Mortgaged Property that is the principal residence of the
debtor. In all cases, the secured creditor is entitled to the value of its
security plus post-petition interest, attorney's fees and costs to the extent
the value of the security exceeds the debt.

      In a Chapter 11 case under the Bankruptcy Code, the lender is precluded
from foreclosing without authorization from the bankruptcy court. The lender's
lien may be transferred to other collateral and/or be limited in amount to the
value of the lender's interest in the collateral as of the date of the
bankruptcy. The loan term may be extended, the interest rate may be adjusted to
market rates and the priority of the loan may be subordinated to bankruptcy
court-approved financing. The bankruptcy court can, in effect, invalidate
due-on-sale clauses through confirmed Chapter 11 plans of reorganization.

      The Bankruptcy Code provides priority to certain tax liens over the
lender's security. This may delay or interfere with the enforcement of rights in
respect of a defaulted Mortgage Loan. In addition, substantive requirements are
imposed upon lenders in connection with the organization and the servicing of
mortgage loans by numerous federal and some state consumer protection laws. The
laws include the federal Truth-in-Lending Act, Real Estate Settlement Procedures
Act, Equal Credit Opportunity Act, Fair Credit Billing Act, Fair Credit
Reporting Act and related statutes and regulations. These federal laws impose
specific statutory liabilities upon lenders who originate loans and who fail to
comply with the provisions of the law. In some cases, this liability may affect
assignees of the loans.

Due-on-Sale Clauses in Mortgage Loans

      Due-on-sale clauses permit the lender to accelerate the maturity of the
loan if the borrower sells or transfers, whether voluntarily or involuntarily,
all or part of the real Mortgaged Property securing the loan without the
lender's prior written consent. The enforceability of these clauses has been the
subject of legislation or litigation in many states, and in some cases,
typically involving single family residential mortgage transactions, their
enforceability has been limited or denied. In any event, the Garn-St. Germain
Depository Institutions Act of 1982 


                                       45
<PAGE>   124

(the "Garn-St. Germain Act") preempts state constitutional, statutory and case
law that prohibits the enforcement of due-on-sale clauses and permits lenders to
enforce these clauses in accordance with their terms, subject to certain
exceptions. As a result, due-on-sale clauses have become generally enforceable
except in those states whose legislatures exercised their authority to regulate
the enforceability of such clauses with respect to mortgage loans that were (i)
originated or assumed during the "window period" under the Garn-St. Germain Act
which ended in all cases not later than October 15, 1982, and (ii) originated by
lenders other than national banks, federal savings institutions and federal
credit unions. FHLMC has taken the position in its published mortgage servicing
standards that, out of a total of eleven "window period states," five states
(Arizona, Michigan, Minnesota, New Mexico and Utah) have enacted statutes
extending, on various terms and for varying periods, the prohibition on
enforcement of due-on-sale clauses with respect to certain categories of window
period loans. Also, the Garn-St. Germain Act does "encourage" lenders to permit
assumption of loans at the original rate of interest or at some other rate less
than the average of the original rate and the market rate.

      In addition, under federal bankruptcy law, due-on-sale clauses may not be
enforceable in bankruptcy proceedings and may, under certain circumstances, be
eliminated in any modified mortgage resulting from such bankruptcy proceeding.

Enforceability of Prepayment and Late Payment Fees

      Forms of notes, mortgages and deeds of trust used by lenders may contain
provisions obligating the borrower to pay a late charge if payments are not
timely made, and in some circumstances may provide for prepayment fees or
penalties if the obligation is paid prior to maturity. In certain states, there
are or may be specific limitations upon the late charges which a lender may
collect from a borrower for delinquent payments. Certain states also limit the
amounts that a lender may collect from a borrower as an additional charge if the
loan is prepaid. Late charges and prepayment fees are typically retained by
servicers as additional servicing compensation. 

Equitable Limitations on Remedies

      In connection with lenders' attempts to realize upon their security,
courts have invoked general equitable principles. The equitable principles are
generally designed to relieve the borrower from the legal effect of his defaults
under the loan documents. Examples of judicial remedies that have been fashioned
include judicial requirements that the lender undertake affirmative and
expensive actions to determine the causes of the borrower's default and the
likelihood that the borrower will be able to reinstate the loan. In some cases,
courts have substituted their judgment for the lender's judgment and have
required that lenders reinstate loans or recast payment schedules in order to
accommodate borrowers who are suffering from temporary financial disability. In
other cases, courts have limited the right of a lender to realize upon his
security if the default under the security agreement is not monetary, such as
the borrower's failure to adequately maintain the Mortgaged Property or the
borrower's execution of secondary financing affecting the Mortgaged Property.
Finally, some courts have been faced with the issue of whether or not federal or
state constitutional provisions reflecting due process concerns for adequate
notice require that borrowers under security agreements receive notices in
addition to the statutorily-prescribed minimums. For the most part, these cases
have upheld the notice provisions as being reasonable or have found that, in
cases involving the sale by a trustee under a deed of trust or by a mortgagee
under a mortgage having a power of sale, there is insufficient state action to
afford constitutional protections to the borrower.

      Most conventional single-family mortgage loans may be prepaid in full or
in part without penalty. The regulations of the Federal Home Loan Bank Board
prohibit the imposition of a prepayment penalty or equivalent fee for or in
connection with the acceleration of a loan by exercise of a due-on-sale clause.
A mortgagee to whom a prepayment in full has been tendered may be compelled to
give either a release of the mortgage or an instrument assigning the existing
mortgage. The absence of a restraint on prepayment, particularly with respect to
mortgage loans having higher mortgage rates, may increase the likelihood of
refinancing or other early retirements of such mortgage loans. 

Applicability of Usury Laws

      Title V of the Depository Institutions Deregulation and Monetary Control
Act of 1980, enacted in March 1980 ("Title V"), provides that state usury
limitations shall not apply to certain types of residential first mortgage loans
originated by certain lenders after March 31, 1980. Similar federal statutes
were in effect with respect to mortgage loans made during the first three months
of 1980. The Federal Home Loan Bank Board is authorized to 


                                       46
<PAGE>   125

issue rules and regulations and to publish interpretations governing
implementation of Title V. Title V authorizes any state to reimpose interest
rate limits by adopting, before April 1, 1983, a state law, or by certifying
that the voters of such state have voted in favor of any provision,
constitutional or otherwise, which expressly rejects an application of the
federal law. Fifteen states adopted such a law prior to the April 1, 1983
deadline. In addition, even where Title V is not so rejected, any state is
authorized by the law to adopt a provision limiting discount points or other
charges on mortgage loans covered by Title V. 

Soldiers' and Sailors' Civil Relief Act of 1940

      Under the Soldiers' and Sailors' Civil Relief Act of 1940, members of all
branches of the military on active duty, including draftees and reservists in
military service, (i) are entitled to have interest rates reduced and capped at
6% per annum, on obligations (including Mortgage Loans) incurred prior to the
commencement of military service for the duration of military service, (ii) may
be entitled to a stay of proceedings on any kind of foreclosure or repossession
action in the case of defaults on such obligations entered into prior to
military service for the duration of military service and (iii) may have the
maturity of such obligations incurred prior to military service extended, the
payments lowered and the payment schedule readjusted for a period of time after
the completion of military service. However, the benefits of (i), (ii), or (iii)
above are subject to challenge by creditors and if, in the opinion of the court,
the ability of a person to comply with such obligations is not materially
impaired by military service, the court may apply equitable principles
accordingly. If a borrower's obligation to repay amounts otherwise due on a
Mortgage Loan included in a Trust Fund for a Series is relieved pursuant to the
Soldiers' and Sailors' Civil Relief Act of 1940, none of the Trust Fund, the
Servicer, the Depositor nor the Trustee will be required to advance such
amounts, and any loss in respect thereof may reduce the amounts available to be
paid to the Holders of the Securities of such Series. Unless otherwise specified
in the related Prospectus Supplement, any shortfalls in interest collections on
Mortgage Loans included in a Trust Fund for a Series resulting from application
of the Soldiers' and Sailors' Civil Relief Act of 1940 will be allocated to each
Class of Securities of such Series that is entitled to receive interest in
respect of such Mortgage Loans in proportion to the interest that each such
Class of Securities would have otherwise been entitled to receive in respect of
such Mortgage Loans had such interest shortfall not occurred.

                                USE OF PROCEEDS

      The Depositor will apply all or substantially all of the net proceeds from
the sale of each Series of Securities for one or more of the following purposes:
(i) to purchase the related Mortgage Loans, (ii) to repay indebtedness which has
been incurred to obtain funds to acquire such Mortgage Loans, (iii) to establish
any Reserve Funds described in the related Prospectus Supplement and (iv) to pay
costs of structuring and issuing such Securities, including the costs of
obtaining Credit Enhancement, if any. If so specified in the related Prospectus
Supplement, the purchase of the Mortgage Loans for a Series may be effected by
an exchange of Securities with the Seller of such Mortgage Loans.

                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS

General

      The following is a summary of certain United States federal income tax
consequences of an investment in the Securities by Holders that acquire their
Securities in their initial offering. This summary is based on the Internal
Revenue Code of 1986 (the "Code") as well as Treasury regulations and
administrative and judicial rulings and practice. Legislative, judicial and
administrative changes may occur, possibly with retroactive effect, that could
alter or modify the continued validity of the statements and conclusions set
forth herein. This summary does not purport to address all federal income tax
matters that may be relevant to particular holders. For example, it generally is
addressed only to original purchasers of the Securities that are U.S. holders"
(as defined below), deals only with Securities held as capital assets within the
meaning of Section 1221 of the Code, and does not address tax consequences to
holders that may be relevant to investors subject to special rules, such as
non-U.S. investors, banks, insurance companies, tax-exempt organizations,
dealers in securities or currencies, electing large partnerships, mutual funds,
REITs, RICs, natural persons, cash method taxpayers, S corporations, estates and
trusts, investors that hold the Securities as part of a hedge, straddle or
integrated or conversion transaction, or holders whose "functional currency" is
not the United States dollar. Further, it does not address alternative minimum
tax consequences or the indirect effects on the holders of equity interests in a
Holder of Securities. Investors should consult their own tax advisors to
determine the United States federal, state, local and other tax consequences of
the purchase, ownership and disposition of the Securities.

      For these purposes, a U.S. holder is (i) a citizen or resident of the
United States, (ii) a corporation or partnership organized in or under the laws
of the United States, any state thereof or the District of Columbia (except, in
the case of a partnership, to the extent provided in Treasury regulations) or
(iii) an estate or trust defined in Section 7701(a)(30)(D) or (E) of the Code,
respectively. "Non-U.S. holder" means any holder that is not a United States
holder.

      Prospective investors should note that no rulings have been or will be
sought from the Internal Revenue Service ("IRS") with respect to any of the U.S.
federal income tax consequences discussed herein and opinions of counsel are not
binding on the IRS or the courts. Thus, no assurance can be given that the IRS
will not take positions contrary to those described below. The opinions of
Orrick, Herrington & Sutcliffe LLP, special counsel to the Depositor, described
herein will be based upon certain representations and assumptions, including,
but not limited to, the assumption that all relevant parties will comply with
the terms of the Trust Agreement and related documents.

      This summary is intended as an explanatory discussion of the possible
effects of the classification of the Trust as a grantor trust or as a
partnership for U.S. federal income tax purposes on investors generally and
related tax matters affecting investors generally, but does not purport to
furnish information in the level of detail or with the attention to the
investor's specific tax circumstances that would be provided by an investor's
own tax adviser. Accordingly, each investor is advised to consult its own
advisers with regard to the tax consequences to it of investing in the
Securities.

      For purposes of the following discussion, except as otherwise provided
herein, the terms "Holder," "Noteholder" and "Certificateholder" refer,
respectively, to the beneficial owner of a Note or Certificate.

      The federal income tax consequences to Holders will vary depending on
whether (i) the Securities of a Series are classified as indebtedness; (ii) the
Securities represent an ownership interest in some or all of the assets included
in the Trust Fund for a Series; or (iii) the Trust Fund relating to a particular
Series of Certificates is treated as a partnership. The Prospectus Supplement
for each Series of Securities will specify how the Securities will be treated
for federal income tax purposes. 

Taxation of Debt Securities

      Interest and Acquisition Discount. Interest (other than original issue
discount) on Securities that are characterized as indebtedness for federal
income tax purposes will be includible in income by holders thereof in
accordance with their usual methods of accounting. Securities characterized as
debt for federal income tax purposes will be referred to hereinafter
collectively as "Debt Securities."


                                       49
<PAGE>   128

      Debt Securities that are Compound Interest Securities will, and certain of
the other Debt Securities may, be issued with "original issue discount" ("OID").
The following discussion is based in part on the rules governing OID which are
set forth in Sections 1271-1275 of the Code and the Treasury regulations issued
thereunder (the "OID Regulations"). A Holder should be aware, however, that the
OID Regulations do not adequately address certain issues relevant to, and in
some instances provide that they are not applicable to, prepayable securities
such as the Debt Securities.

      In general, OID, if any, will equal the difference between the stated
redemption price at maturity of a Debt Security and its issue price. A holder of
a Debt Security must include such OID in gross income as ordinary interest
income as it accrues. In general, OID is included in income in advance of (or
concurrent with) the receipt of the cash representing that income. The amount of
OID on a Debt Security will be considered to be zero if it is less than a de
minimis amount determined under the Code.

      The issue price of a Debt Security is the first price at which a
substantial amount of Debt Securities of that class are sold to the public
(excluding sales to bond houses, brokers, underwriters or wholesalers). If less
than a substantial amount of a particular class of Debt Securities is sold for
cash on or prior to the Closing Date, the issue price for such class will be
treated as the fair market value of such class on the Closing Date. The issue
price of a Debt Security will also include the amount paid by an initial Debt
Security holder for accrued interest that relates to a period prior to the issue
date of the Debt Security.

      The stated redemption price at maturity of a Debt Security is equal to the
total of all payments to be made on such Debt Security other than "qualified
stated interest." In addition, that portion of the first interest payment in
excess of interest accrued from the Closing Date to the first Distribution Date
will be treated for federal income tax reporting purposes as includible in the
stated redemption price at maturity, and as excludible from income when received
as a payment of interest on the first Distribution Date (except to the extent of
any accrued market discount as of that date). The OID Regulations suggest,
however, that some or all of this pre-issuance accrued interest may be treated
as a separate asset (and hence not includible in a Debt Securities' issue price
or stated redemption price at maturity), whose cost is recovered entirely out of
interest paid on the first Distribution Date. It is unclear how an election to
do so would be made under the OID Regulations and whether such election could be
unilaterally made by a Holder. Under the OID Regulations, qualified stated
interest generally means interest payable at a single fixed rate that
appropriately takes into account the length of the interval between payments or
certain qualified variable rates provided that such interest payments are
unconditionally payable at intervals of one year or less during the entire term
of the Debt Security. In the case of Compound Interest Securities, certain
Interest Weighted Securities, and certain of the other Debt Securities, none of
the payments under the instrument will be considered qualified stated interest,
and thus the aggregate amount of all payments will be included in the stated
redemption price at maturity.

      Under the de minimis rule, OID on a Debt Security will be considered to be
zero if such OID is less an 0.25% of the stated redemption price at maturity of
the Debt Security multiplied by the weighted average maturity of the Debt
Security. For this purpose, the weighted average maturity of the Debt Security
is computed as the sum of the amounts determined by multiplying the number of
full years (i.e., rounding down partial years) from the issue date until each
distribution in reduction of stated redemption price at maturity is scheduled to
be made by a fraction, the numerator of which is the amount of each distribution
included in the stated redemption price at maturity of the Debt Security and the
denominator of which is the stated redemption price at maturity of the Debt
Security. The IRS may take the position that this rule should be applied taking
into account the Prepayment Assumption (defined below). Under the OID
Regulations, Debt Securities bearing only qualified stated interest except for
any "teaser" rate, interest holiday or other similar provision are treated as
subject to the de minimis rule if the greater of the foregone interest (as
described in such regulations) or any excess of the Debt Securities' stated
principal amount over their issue price is less than such de minimis amount.
Holders generally must report de minimis OID pro rata as principal payments are
received, and such income will be capital gain if the Debt Security is held as a
capital asset. However, accrual method holders may elect to accrue all de
minimis OID as well as market discount under a constant interest method.

      The holder of a Debt Security issued with OID must include in gross
income, for all days during its taxable year on which it holds such Debt
Security, the sum of the "daily portions" of such original issue discount. The
amount of OID includible in income by a holder will be computed by allocating to
each day during a taxable year a pro rata portion of the original issue discount
that accrued during the relevant accrual period. In the case of a Debt Security
the principal payments on which are not subject to acceleration resulting from
prepayments on the Mortgage Loans, the amount of OID includible in income of a
Holder for an accrual period (generally the period 


                                       50
<PAGE>   129

over which interest accrues on the debt instrument) will equal the product of
the yield to maturity of the Debt Security and the adjusted issue price of the
Debt Security, reduced by any payments of qualified stated interest. The
adjusted issue price is the sum of its issue price plus prior accruals or OID,
reduced by the total payments made with respect to such Debt Security in all
prior periods, other than qualified stated interest payments.

      The amount of OID to be included in income by a holder of a debt
instrument, such as certain Classes of the Debt Securities, that is subject to
acceleration due to prepayments on other debt obligations securing such
instruments (a "Pay-Through Security"), is computed by taking into account the
anticipated rate of prepayments assumed in pricing the debt instrument (the
"Prepayment Assumption"). The amount of OID that will accrue during an accrual
period on a Pay-Through Security is the excess (if any) of (i) the sum of (a)
the present value of all payments remaining to be made on the Pay-Through
Security as of the close of the accrual period and (b) the payments during the
accrual period of amounts included in the stated redemption price of the
Pay-Through Security, over (ii) the adjusted issue price of the Pay-Through
Security at the beginning of the accrual period. The present value of the
remaining payments referred to in the preceding sentence will be determined on
the basis of three factors: (i) the original yield to maturity (giving effect to
the Prepayment Assumption) of the Pay-Through Security (determined on the basis
of compounding at the end of each accrual period and properly adjusted for the
length of the accrual period), (ii) events (including actual prepayments) that
have occurred before the end of the accrual period and (iii) the assumption that
the remaining payments will be made in accordance with the original Prepayment
Assumption. The effect of this method is to increase the portions of OID
required to be included in income by a Holder to take into account prepayments
with respect to the Mortgage Loans at a rate that exceeds the Prepayment
Assumption, and to decrease (but not below zero for any period) the portions of
original issue discount required to be included in income by a Holder of a
Pay-Through Security to take into account prepayments with respect to the
Mortgage Loans at a rate that is slower than the Prepayment Assumption. Although
original issue discount will be reported to Holders of Pay-Through Securities
based on the Prepayment Assumption, no representation is made to Holders that
Mortgage Loans will be prepaid at that rate or at any other rate.

      A subsequent holder of a Debt Security will also be required to include
OID in gross income, but such a holder who purchases a Debt Security for an
amount that exceeds its adjusted issue price will be entitled (as will an
initial holder who pays more than a Debt Security's issue price) to offset such
OID by comparable economic accruals of portions of such excess.

      Effects of Defaults and Delinquencies. Holders will be required to report
income with respect to the related Securities under an accrual method without
giving effect to delays and reductions in distributions attributable to a
default or delinquency on the Mortgage Loans, except possibly to the extent that
it can be established that such amounts are uncollectible. As a result, the
amount of income (including OID) reported by a holder of a Debt Security in any
period could significantly exceed the amount of cash distributed to such holder
in that period. The holder will eventually be allowed a loss (or will be allowed
to report a lesser amount of income) to the extent that the aggregate amount of
distributions on the Securities is reduced as a result of a Mortgage Loan
default. However, the timing and character of such losses or reductions in
income are uncertain and, accordingly, holders of Securities should consult
their own tax advisors on this point.

      Interest Weighted Securities. It is not clear how income should be accrued
with respect to Stripped Securities (as defined under "-Tax Status as a Grantor
Trust; General" herein) the payments on which consist solely or primarily of a
specified portion of the interest payments on mortgages held by the Trust Fund
("Interest Weighted Securities"). The Depositor intends to take the position
that all of the income derived from an Interest Weighted Security should be
treated as OID and that the amount and rate of accrual of such OID should be
calculated by treating the Interest Weighted Security as a Compound Interest
Security. Alternatively, the IRS could assert that an Interest Weighted Security
should be taxable under the rules governing bonds issued with contingent
payments.

      Variable Rate Debt Securities. In the case of Debt Securities bearing
interest at a rate that varies directly, according to a fixed formula, with an
objective index, it appears that (i) the yield to maturity of such Debt
Securities and (ii) in the case of Pay-Through Securities, the present value of
all payments remaining to be made on such Debt Securities, should be calculated
as if the interest index remained at its value as of the issue date of such
Securities. Because the proper method of adjusting accruals of OID on a variable
rate Debt Security is uncertain, holders of variable rate Debt Securities should
consult their own tax advisers regarding the appropriate treatment of such
Securities for federal income tax purposes.

      Market Discount. A purchaser of a Security may be subject to the market
discount rules of Sections 1276-1278 of the Code. A Holder that acquires a Debt
Security with more than a prescribed de minimis amount of


                                       51
<PAGE>   130

"market discount" (generally, the excess of the principal amount of the Debt
Security or, in the case of a Debt security issued with OID, the Debt
Securities' adjusted issue price, over the purchaser's purchase price) will be
required to include accrued market discount in income as ordinary income in each
month, but limited to an amount not exceeding the principal payments on the Debt
Security received in that month and, if the Securities are sold, the gain
realized. Such market discount would accrue in a manner to be provided in
Treasury regulations but, until such regulations are issued, such market
discount would, in general, accrue either (i) on the basis of a constant yield,
or (ii) in the ratio of (a) in the case of Securities (or in the case of a
Pass-Through Security, as set forth below, the Mortgage Loans underlying such
Security) not originally issued with original issue discount, stated interest
payable in the relevant period to total stated interest remaining to be paid at
the beginning of the period or (b) in the case of Securities (or, in the case of
a Pass-Through Security, as described below, the Mortgage Loans underlying such
Security) originally issued with original issue discount, OID in the relevant
period to total OID remaining to be paid as of the beginning of such period. The
Prepayment Assumption, if any, used in calculating the accrual of OID is to be
used in calculating the accrual of market discount under any of the above
methods.

      Section 1277 of the Code provides that the excess of interest paid or
accrued to purchase or carry a Security (or, in the case of a Pass-Through
Security, as described below, the underlying Mortgage Loans) with market
discount over interest received on such Security is allowed as a current
deduction only to the extent such excess is greater than the market discount
that accrued during the taxable year in which such interest expense was
incurred. In general, the deferred portion of any interest expense will be
deductible when such market discount is included in income, including upon the
sale, disposition, or repayment of the Security (or in the case of a
Pass-Through Security, an underlying Mortgage Loan). A holder may elect to
include market discount in income currently as it accrues, on all market
discount obligations acquired by such holder during the taxable year such
election is made and thereafter, in which case the interest deferral rule will
not apply. Any such election is irrevocable without the consent of the IRS.

      Premium. A holder who purchases a Debt Security (other than an Interest
Weighted Security at a cost greater than its stated redemption price at
maturity, generally will be considered to have purchased the Security at a
premium, which it may elect to amortize as an offset to interest income on such
Security (and not as a separate deduction item) on a constant yield method.
Although no regulations addressing the computation of premium accrual on
securities similar to the Securities have been issued, the legislative history
of the 1986 Act indicates that premium is to be accrued in the same manner as
market discount. Accordingly, it appears that the accrual of premium on a Class
of Pay-Through Securities will be calculated using the prepayment assumption (if
any) used in pricing such Class. If a holder makes an election to amortize
premium on a Debt Security, such election will apply to all taxable debt
instruments (including all REMIC regular interests and all pass-through
certificates representing ownership interests in a trust holding debt
obligations) held by the holder at the beginning of the taxable year in which
the election is made, and to all taxable debt instruments acquired thereafter by
such holder, and will be irrevocable without the consent of the IRS. Purchasers
who pay a premium for the Securities should consult their tax advisers regarding
the election to amortize premium and the method to be employed.

      Election to Treat All Interest as Original Issue Discount. The OID
Regulations permit a holder of a Debt Security to elect to accrue all interest,
discount (including de minimis market or original issue discount) and premium in
income as interest, based on a constant yield method. If such an election were
to be made with respect to a Debt Security with market discount, the holder of
the Debt Security would be deemed to have made an election to include in income
currently market discount with respect to all other debt instruments having
market discount that such holder of the Debt Security acquires during the year
of the election or thereafter. Similarly, a holder of a Debt Security that makes
this election for a Debt Security that is acquired at a premium will be deemed
to have made an election to amortize bond premium with respect to all debt
instruments having amortizable bond premium that such holder owns or acquires.
The election to accrue interest, discount and premium on a constant yield method
with respect to a Debt Security is irrevocable without the consent of the IRS.

Tax Status as a Grantor Trust

      General. The related Prospectus Supplement may provide that Orrick,
Herrington & Sutcliffe LLP, special counsel to the Depositor, will deliver an
opinion generally to the effect that the Trust Fund relating to a Series of
Securities will be classified for federal income tax purposes as a grantor trust
under Subpart E, Part 1 of Subchapter J of the Code and not as an association
taxable as (or a publicly traded partnership treated as) a corporation (the
Securities of such Series, "Pass-Through Securities"). In some Series there will
be no separation of the principal and interest payments on the Mortgage Loans.
In such circumstances, a Holder will be considered to have


                                       52
<PAGE>   131

purchased a pro rata undivided interest in each of the Mortgage Loans. In other
cases ("Stripped Securities"), sale of the Securities will produce a separation
in the interest payments on the ownership of all or a portion of the principal
payments from all or a portion of Mortgage Loans.

      Each Holder must report on its federal income tax return its share of the
gross income derived from the Mortgage Loans (not reduced by the amount payable
as fees to the Trustee and the Servicer and similar fees (collectively, the
"Servicing Fee")), at the same time and in the same manner as such items would
have been reported under the Holder's tax accounting method had it held its
interest in the Mortgage Loans directly, received directly its share of the
amounts received with respect to the Mortgage Loans, and paid directly its share
of the Servicing Fees. In the case of Pass-Through Securities other than
Stripped Securities, such income will consist of a pro rata share of all of the
income derived from all of the Mortgage Loans and, in the case of Stripped
Securities, such income will consist of a pro rata share of the income derived
from each stripped bond or stripped coupon in which the Holder owns an interest.
The holder of a Security will generally be entitled to deduct such Servicing
Fees under Section 162 or Section 212 of the Code to the extent that such
Servicing Fees represent "reasonable" compensation for the services rendered by
the Trustee and the Servicer (or third parties that are compensated for the
performance of services). In the case of a noncorporate holder, however,
Servicing Fees (to the extent not otherwise disallowed, e.g., because they
exceed reasonable compensation) will be deductible in computing such holder's
regular tax liability only to the extent that such fees, when added to other
miscellaneous itemized deductions, exceed 2% of adjusted gross income and may
not be deductible to any extent in computing such holder's alternative minimum
tax liability.

      Discount or Premium on Pass-Through Securities. The holder's purchase
price of a Pass-Through Security is to be allocated among the Mortgage Loans in
proportion to their fair market values, determined as of the time of purchase of
the Securities. In the typical case, the Trustee (to the extent necessary to
fulfill its reporting obligations) will treat each Mortgage Loan as having a
fair market value proportional to the share of the aggregate principal balances
of all of the Mortgage Loans that it represents, since the Securities, unless
otherwise specified in the applicable Prospectus Supplement, will have a
relatively uniform interest rate and other common characteristics. To the extent
that the portion of the purchase price of a Pass-Through Security allocated to a
Mortgage Loan (other than to a right to receive any accrued interest thereon and
any undistributed principal payments) is less than or greater than the principal
balance of the Mortgage Loan, the interest in the Mortgage Loan allocable to the
Pass-Through Security will be deemed to have been acquired at a discount or
premium, respectively.

      The treatment of any discount will depend on whether the discount
represents OID or market discount. In the case of a Mortgage Loan with OID in
excess of a prescribed de minimis amount or a Stripped Security (see below), a
holder of a Security will be required to report as interest income in each
taxable year its share of the amount of OID that accrues during that year in the
manner described above. OID with respect to a Mortgage Loan could arise, for
example, by virtue of the financing of points by the originator of the Mortgage
Loan, or by virtue of the charging of points by the originator of the Mortgage
Loan in an amount greater than a statutory de minimis exception, in
circumstances under which the points are not currently deductible pursuant to
applicable Code provisions. Any market discount or premium on a Mortgage Loan
will be includible in income, generally in the manner described above, except
that in the case of Pass-Through Securities, market discount is calculated with
respect to the Mortgage Loans underlying the Certificate, rather than with
respect to the Security.

      Stripped Securities. A Stripped Security may represent a right to receive
only a portion of the interest payments on the Mortgage Loans, a right to
receive only principal payments on the Mortgage Loans, or a right to receive
certain payments of both interest and principal. Certain Stripped Securities
("Ratio Strip Securities") may represent a right to receive differing
percentages of both the interest and principal on each Loan. Pursuant to Section
1286 of the Code, the separation of ownership of the right to receive some or
all of the interest payments on an obligation from ownership of the right to
receive some or all of the principal payments results in the creation of
"stripped bonds" with respect to principal payments and "stripped coupons" with
respect to interest payments. Section 1286 of the Code applies the OID rules to
stripped bonds and stripped coupons. For purposes of computing original issue
discount, a stripped bond or a stripped coupon is treated as a debt instrument
issued on the date that such stripped interest is purchased with an issue price
equal to its purchase price or, if more than one stripped interest is purchased,
the ratable share of the purchase price allocable to such stripped interest.

      Servicing fees in excess of reasonable servicing fees ("excess servicing")
will be treated under the stripped bond rules. Under such rules, excess
servicing will be treated as a stripped coupon. If the excess servicing fee is
no more than 100 basis points (i.e. 1% interest on the Mortgage Loan principal
balance) or the Securities are initially 


                                       53
<PAGE>   132

sold with a de minimis discount (assuming no prepayment assumption is required),
any non-de minimis discount arising from a subsequent transfer of the Securities
should be treated as market discount. The IRS appears to require that reasonable
servicing fees be calculated on a Loan by Loan basis, which could result in some
Mortgage Loans being treated as having more than 100 basis points of interest
stripped off.

      The Code, OID Regulations and judicial decisions provide no direct
guidance as to how the interest and original issue discount rules are to apply
to Stripped Securities and other Pass-Through Securities. Under the method
described above for Pay-Through Securities (the "Cash Flow Bond Method"), a
prepayment assumption is used and periodic recalculations are made which take
into account with respect to each accrual period the effect of prepayments
during such period. It is believed, however, that the Cash Flow Bond Method is a
reasonable method of reporting income for such Securities, and it is expected
that OID will be reported on that basis unless otherwise specified in the
related Prospectus Supplement. In applying the calculation to Pass-Through
Securities, the Trustee will treat all payments to be received by a holder with
respect to the underlying Mortgage Loans as payments on a single installment
obligation. The IRS could, however, assert that original issue discount must be
calculated separately for each Mortgage Loan underlying a Security.

      Under certain circumstances, if the Mortgage Loans prepay at a rate faster
than the Prepayment Assumption, the use of the Cash Flow Bond Method may
accelerate a Holder's recognition of income. If, however, the Mortgage Loans
prepay at a rate slower than the Prepayment Assumption, the use of this method
may decelerate a Holder's recognition of income.

      In the case of a Stripped Security that is an Interest Weighted Security,
the Trustee intends, absent contrary authority, to report income to Security
holders as OID, in the manner described above for Interest Weighted Securities.

      Possible Alternative Characterizations. The characterizations of the
Stripped Securities described above are not the only possible interpretations of
the applicable Code provisions. Given the variety of alternatives for treatment
of the Stripped Securities and the different federal income tax consequences
that result from each alternative, potential purchasers are urged to consult
their own tax advisers regarding the proper, treatment of the Securities for
federal income tax purposes. 

Sale or Exchange

      Subject to the discussion below with respect to Trust Funds treated as a
partnership, a Holder's tax basis in its Security is the price such holder pays
for a Security, plus amounts of original issue or market discount included in
income and reduced by any payments received (other than qualified stated
interest payments), and any amortized premium. Gain or loss recognized on a
sale, exchange, or redemption of a Security, measured by the difference between
the amount realized and the Security's basis as so adjusted, will generally be
capital gain or loss, assuming that the Security is held as a capital asset. 

Tax Treatment of Foreign Investors

      Subject to the discussion below with respect to Trust Funds treated as a
partnership, unless interest (including OID) paid on a Security is considered to
be "effectively connected" with a trade or business conducted in the United
States by a nonresident alien individual, foreign partnership or foreign
corporation ("Nonresidents"), such interest will normally qualify as portfolio
interest (except where (i) the recipient is a holder, directly or by
attribution, of 10% or more of the capital or profits interest in the issuer or
any of the beneficial owners of the issuer (or, with respect to any beneficial
owner that is a corporation, 10% or more of the total combined voting power of
all classes of stock entitled to vote), or (ii) the recipient is a controlled
foreign corporation to which the issuer is a related person) and will be exempt
from federal income tax. Upon receipt of appropriate ownership statements, the
issuer normally will be relieved of obligations to withhold tax from such
interest payments. These provisions supersede the generally applicable
provisions of United States law that would otherwise require the issuer to
withhold at a 30% rate (unless such rate were reduced or eliminated by an
applicable tax treaty) on, among other things, interest and other fixed or
determinable, annual or periodic income paid to Nonresidents.

      Interest and OID of Holders who are foreign persons are not subject to
withholding if they are effectively connected with a United States business
conducted by the Holder. They will, however, generally be subject to the regular
United States income tax. 


                                       54

Tax Characterization of the Trust as a Partnership

      The related Prospectus Supplement may provide that Orrick, Herrington &
Sutcliffe LLP, special counsel to the Depositor, will deliver its opinion
generally to the effect that the Trust Fund relating to a specific Series of
Securities will be a partnership (or possibly a grantor trust) and not an
association (or publicly traded partnership) taxable as a corporation for
federal income tax purposes. This opinion will be based on the assumption that
the terms of the Trust Agreement and related documents will be complied with,
and on counsel's conclusions that either the nature of the income of the Trust
Fund will exempt it from the rule that certain publicly traded partnerships are
taxable as corporations or the issuance of the Certificates has been structured
as a private placement under an IRS safe harbor, so that the Trust Fund will not
be characterized as a publicly traded partnership taxable as a corporation.

      If the Trust Fund were taxable as a corporation for federal income tax
purposes, the Trust Fund would be subject to corporate income tax on its taxable
income. The Trust Fund's taxable income would include all its income, possibly
reduced by its interest expense on the Notes. Any such corporate income tax
could materially reduce cash available to make payments on the Notes and
distributions on the Certificates, and Certificateholders could be liable for
any such tax that is unpaid by the Trust Fund. 

Tax Consequences to Holders of the Notes

      Treatment of the Notes as Indebtedness. The Trust Fund will agree, and the
Noteholders will agree by their purchase of Notes, to treat the Notes as debt
for federal income tax purposes. Special counsel to the Depositor will, except
as otherwise provided in the related Prospectus Supplement, advise the Depositor
that the Notes will be classified as debt for federal income tax purposes. The
discussion below assumes this characterization of the Notes is correct.

      OID, Stripped Securities, etc. The discussion below assumes that all
payments on the Notes are denominated in U.S. dollars, and that the Notes are
not Stripped Securities. Moreover, the discussion assumes that the interest
formula for the Notes meets the requirements for "qualified stated interest"
under the OID regulations, and that any OID on the Notes does not exceed a de
minimis amount, all within the meaning of the OID regulations. If these
conditions are not satisfied with respect to any given series of Notes,
additional tax considerations with respect to such Notes will be disclosed in
the applicable Prospectus Supplement.

      Interest Income on the Notes. Based on the above assumptions, except as
discussed in the following paragraph, the Notes will not be considered issued
with OID. The stated interest thereon will be taxable to a Noteholder as
ordinary interest income when received or accrued in accordance with such
Noteholder's method of tax accounting. Under the OID regulations, a holder of a
Note issued with a de minimis amount of OID must include such OID in income, on
a pro rata basis, as principal payments are made on the Note. A purchaser who
buys a Note for more or less than its principal amount will generally be
subject, respectively, to the premium amortization or market discount rules of
the Code.

      Sale or Other Disposition. If a Noteholder sells a Note, the holder will
recognize gain or loss in an amount equal to the difference between the amount
realized on the sale and the holder's adjusted tax basis in the Note. The
adjusted tax basis of a Note to a particular Noteholder will equal the holder's
cost for the Note, increased by any market discount, acquisition discount, OID
and gain previously included by such Noteholder in income with respect to the
Note and decreased by the amount of bond premium (if any) previously amortized
and by the amount of principal payments previously received by such Noteholder
with respect to such Note. Any such gain or loss will be capital gain or loss if
the Note was held as a capital asset, except for gain representing accrued
interest and accrued market discount not previously included in income. Capital
losses generally may be used only to offset capital gains.

      Foreign Holders. Interest payments made (or accrued) to a Noteholder who
is a nonresident alien, foreign corporation or other non-United States person (a
"foreign person") generally will be considered "portfolio interest", and
generally will not be subject to United States federal income tax and
withholding tax, if the interest is not effectively connected with the conduct
of a trade or business within the United States by the foreign person and the
foreign person (i) is not actually or constructively a "10% shareholder" (within
the meaning of Section 871(h)(3)(B) of the Code) of the Trust or of any
beneficial owner therein or a "controlled foreign corporation" with respect to
which the Trust or any beneficial owner is a "related person" within the meaning
of the Code and (ii) provides the proper certifications. If such interest is not
portfolio interest, then it will be subject to United States federal income and
withholding tax at a rate of 30 percent, unless reduced or eliminated pursuant
to an applicable tax treaty.


                                       55
<PAGE>   134

      Any capital gain realized on the- sale, redemption, retirement or other
taxable disposition of a Note by a foreign person will be exempt from United
States federal income and withholding tax, provided that (i) such gain is not
effectively connected with the conduct of a trade or business in the United
States by the foreign person and (ii) in the case of an individual foreign
person, the foreign person is not present in the United States for 183 days or
more in the taxable year.

      Possible Alternative Treatments of the Notes. If, contrary to the opinion
of special counsel to the Depositor, the IRS successfully asserted that one or
more of the Notes did not represent debt for federal income tax purposes, the
Notes might be treated as equity interests in the Trust Fund. If so treated, the
Trust Fund might be a publicly traded partnership treated as a corporation, with
the adverse consequences described above (and the publicly traded partnership
would not be able to reduce its taxable income by deductions for interest
expense on Notes recharacterized as equity). Further, treatment of the Notes as
equity interests in such a publicly traded partnership could have adverse tax
consequences to certain holders. For example, income to certain tax-exempt
entities (including pension funds) would be "unrelated business taxable income",
income to foreign holders generally would be subject to U.S. tax and U.S. tax
return filing and withholding requirements, and individual holders might be
subject to certain limitations on their ability to deduct their share of the
Trust Fund's expenses. 

Tax Consequences to Holders of the Certificates

      Treatment of the Trust Fund as a Partnership. The Trust Fund and the
Servicer will agree, and the Certificateholders will agree by their purchase of
Certificates, to treat the Trust Fund as a partnership for purposes of federal
and state income tax, franchise tax and any other tax measured in whole or in
part by income, with the assets of the partnership being the assets held by the
Trust Fund, the partners of the partnership being the Certificateholders, and
the Notes being debt of the partnership. However, the proper characterization of
the arrangement involving the Trust Fund, the Certificates, the Notes and the
Servicer is not clear because there is no authority on transactions closely
comparable to that contemplated herein.

      A variety of alternative characterizations are possible. For example,
because the Certificates have certain features characteristic of debt, the
Certificates (while unlikely) might be considered debt of the Trust Fund. The
following discussion assumes that the Certificates represent equity interests in
a partnership.

      Stripped Securities, etc. The following discussion assumes that all
payments on the Certificates are denominated in U.S. dollars, none of the
Certificates are Stripped Securities, and that a Series of Securities includes a
single class of Certificates. If these conditions are not satisfied with respect
to any given Series of Certificates, additional tax considerations with respect
to such Certificates will be disclosed in the applicable Prospectus Supplement.

      Partnership Taxation. As a partnership, the Trust Fund will not be subject
to federal income tax. Rather, each Certificateholder will be required to
separately take into account such holder's allocated share of income, gains,
losses, deductions and credits of the Trust Fund. Such items generally will have
the same character (ordinary or capital, short-term or long-term) and source in
the hands of each Certificateholder as they have in the hands of the Trust Fund.
The Trust Fund's income will consist primarily of interest and finance charges
earned on the Mortgage Loans (including appropriate adjustments for market
discount, OID and bond premium) and any gain upon collection or disposition of
Mortgage Loans. The Trust Fund's deductions will consist primarily of interest
accruing with respect to the Notes, servicing and other fees, and losses or
deductions upon collection or disposition of Mortgage Loans.

      The tax items of a partnership are allocable to the partners in accordance
with the Code, Treasury regulations and the partnership agreement (here, the
Trust Agreement and related documents). The Trust Agreement will provide, in
general, that the Certificateholders will be allocated taxable income of the
Trust Fund for each month equal to the sum of (i) the interest that accrues on
the Certificates in accordance with their terms for such month, including
interest accruing at the Pass Through Rate for such month and interest on
amounts previously due on the Certificates but not yet distributed; (ii) any
Trust Fund income attributable to discount on the Mortgage Loans that
corresponds to any excess of the principal amount of the Certificates over their
initial issue price; (iii) prepayment premium payable to the Certificateholders
for such month; and (iv) any other amounts of income payable to the
Certificateholders for such month. Such allocation will be reduced by any
amortization by the Trust Fund of premium on Mortgage Loans that corresponds to
any excess of the issue price of Certificates over their principal amount. All
remaining taxable income of the Trust Fund may be allocated to the Depositor or
may be allocated pro rata among the Certificateholders. Based on the economic
arrangement of the parties, this approach 


                                       56
<PAGE>   135

for allocating Trust Fund income should be permissible under applicable Treasury
regulations, although no assurance can be given that the IRS would not require a
greater amount of income to be allocated to the Certificateholders. Moreover,
even under the foregoing method of allocation, Certificateholders may be
allocated income equal to the entire Pass Through Rate plus the other items
described above even though the Trust Fund might not have sufficient cash to
make current cash distributions of such amount. Thus, cash basis holders will in
effect be required to report income from the Certificates on the accrual basis
and Certificateholders may become liable for taxes on Trust Fund income even if
they have not received cash from the Trust Fund to pay such taxes. In addition,
because tax allocations and tax reporting will be done on a uniform basis for
all Certificateholders, but Certificateholders may be purchasing Certificates at
different times and at different prices, Certificateholders may be required to
report on their tax returns taxable income that is greater or less than the
amount reported to them by the Trust Fund. In addition, if the Trust Fund's
payments on the Certificates is payable to the Certificateholders without regard
to the income of the Trust Fund, the Trust Fund's payment of such amounts to
Certificateholders may be treated as "guaranteed payments" within the meaning of
Section 707(c) of the Code, and not as a distributive share of the Trust Fund's
income. Such guaranteed payments will constitute ordinary income to a
Certificateholder but may not be considered interest income for U.S. federal
income tax purposes.

      All of the taxable income allocated to a Certificateholder that is a
pension, profit sharing or employee benefit plan or other tax-exempt entity
(including an individual retirement account) will constitute "unrelated business
taxable income generally taxable to such a holder under the Code.

      An individual taxpayer's share of expenses of the Trust Fund (including
fees to the Servicer but not interest expense) would be miscellaneous itemized
deductions. Such deductions might be disallowed to the individual in whole or in
part and might result in such holder being taxed on an amount of income that
exceeds the amount of cash actually distributed to such holder over the life of
the Trust Fund.

      The Trust Fund intends to make all tax calculations relating to income and
allocations to Certificateholders on an aggregate basis. If the IRS were to
require that such calculations be made separately for each Mortgage Loan, the
Trust Fund might be required to incur additional expense but it is believed that
there would not be a material adverse effect on Certificateholders.

      Discount and Premium. The trust may have OID income, since the Mortgage
Loans may have been issued with OID. In addition, the purchase price paid by the
Trust Fund for the Mortgage Loans may be greater or less than the remaining
principal balance of the Mortgage Loans at the time of purchase. If so, the
Mortgage Loan will have been acquired at a premium or discount, as the case may
be. (As indicated above, the Trust Fund will make this calculation on an
aggregate basis, but might be required to recompute it on a Loan by Loan basis.)

      If the Trust Fund acquires the Mortgage Loans at a market discount or
premium, the Trust Fund will elect to include any such discount in income
currently as it accrues over the life of the Mortgage Loans or to offset any
such premium against interest income on the Mortgage Loans. As indicated above,
a portion of such market discount income or premium deduction may be allocated
to Certificateholders.

      Section 708 Termination. Under Section 708 of the Code, the Trust Fund
will be deemed to terminate for federal income tax purposes if 50% or more of
the capital and profits interests in the Trust Fund are sold or exchanged within
a 12-month period. If such a termination occurs, the Trust Fund will be
considered to have transferred all of its assets and liabilities to a new
partnership and then to have immediately liquidated and distributed the
interests in the new partnership to the continuing Certificateholders. The Trust
Fund will not comply with certain technical requirements that might apply when
such a constructive termination occurs. As a result, the Trust Fund may be
subject to certain tax penalties and may incur additional expenses if it is
required to comply with those requirements. Furthermore, the Trust Fund might
not be able to comply due to lack of data.

      Disposition of Certificates. Generally, capital gain or loss will be
recognized on a sale of Certificates in an amount equal to the difference
between the amount realized and the seller's tax basis in the Certificates sold.
A Certificateholder's tax basis in a Certificate will generally equal the
holder's cost increased by the holder's share of Trust Fund income and decreased
by any distributions received with respect to such Certificate. In addition,
both the tax basis in the Certificates and the amount realized on a sale of a
Certificate would include the holder's share of the Notes and other liabilities
of the Trust Fund. A holder acquiring Certificates at different prices may be
required to maintain a single aggregate adjusted tax basis in such Certificates,
and, upon sale or other disposition of some of the Certificates, allocate a
portion of such aggregate tax basis to the Certificates sold (rather than
maintaining a separate tax basis in each Certificate for purposes of computing
gain or loss on a sale of that Certificate).


                                       57
<PAGE>   136

      Any gain on the sale of a Certificate attributable to the holder's share
of unrecognized accrued market discount on the Mortgage Loans would generally be
treated as ordinary income to the holder and would give rise to special tax
reporting requirements. The Trust Fund does not expect to have any other assets
that would give rise to such special reporting requirements. Thus, to avoid
those special reporting requirements, the Trust Fund will elect to include
market discount in income as it accrues.

      If a Certificateholder is required to recognize an aggregate amount of
income (not including income attributable to disallowed itemized deductions
described above) over the life of the Certificates that exceeds the aggregate
cash distributions with respect thereto, such excess will generally give rise to
a capital loss upon the retirement of the Certificates.

      Allocations Between Transferors and Transferees. In general, the Trust
Fund's taxable income and losses will be determined monthly and the tax items
for a particular calendar month will be apportioned among the Certificateholders
in proportion to the principal amount of Certificates owned by them as of the
close of the last day of such month. As a result, a holder purchasing
Certificates may be allocated tax items (which will affect its tax liability and
tax basis) attributable to periods before it purchased its Certificates.

      The use of such a monthly convention may not be permitted by existing
regulations. If a monthly convention is not allowed (or only applies to
transfers of less than all of the partner's interest), taxable income or losses
of the Trust Fund might be reallocated among the Certificateholders. The Trust
Fund's method of allocation between transferors and transferees may be revised
to conform to a method permitted by future regulations.

      Section 754 Election. In the event that a Certificateholder sells its
Certificates at a profit (loss), the purchasing Certificateholder will have a
higher (lower) basis in the Certificates than the selling Certificateholder had.
The tax basis of the Trust Fund's assets will not be adjusted to reflect that
higher (or lower) basis unless the Trust Fund were to file an election under
Section 754 of the Code. In order to avoid the administrative complexities that
would be involved in keeping accurate accounting records, as well as potentially
onerous information reporting requirements, the Trust Fund will not make such
election. As a result, Certificateholders might be allocated a greater or lesser
amount of Trust Fund income than would be appropriate based on their own
purchase price for Certificates.

      Administrative Matters. The Owner Trustee is required to keep or have kept
complete and accurate books of the Trust Fund. Such books will be maintained for
financial reporting and tax purposes on an accrual basis and the fiscal year of
the Trust will be the calendar year. The Trustee will file a partnership
information return (IRS Form 1065) with the IRS for each taxable year of the
Trust Fund and will report each Certificateholder's allocable share of items of
Trust Fund income and expense to holders and the IRS on Schedule K-1. The Trust
Fund will provide the Schedule K-1 information to nominees that fail to provide
the Trust Fund with the information statement described below and such nominees
will be required to forward such information to the beneficial owners of the
Certificates. Generally, holders must file tax returns that are consistent with
the information return filed by the Trust Fund or be subject to penalties unless
the holder notifies the IRS of all such inconsistencies.

      Under Section 6031 of the Code, any person that holds Certificates as a
nominee at any time during a calendar year is required to furnish the Trust Fund
with a statement containing certain information on the nominee, the beneficial
owners and the Certificates so held. Such information includes (i) the name,
address and taxpayer identification number of the nominee and (ii) as to each
beneficial owner (x) the name, address and identification number of such person,
(y) whether such person is a United States person, a tax-exempt entity or a
foreign government, an international organization, or any wholly owned agency or
instrumentality of either of the foregoing, and (z) certain information on
Certificates that were held, bought or sold on behalf of such person throughout
the year. In addition, brokers and financial institutions that hold Certificates
through a nominee are required to furnish directly to the Trust Fund information
as to themselves and their ownership of Certificates. A clearing agency
registered under Section 17A of the Exchange Act is not required to furnish any
such information statement to the Trust Fund. The information referred to above
for any calendar year must be furnished to the Trust Fund on or before the
following January 31. Nominees, brokers and financial institutions that fail to
provide the Trust Fund with the information described above may be subject to
penalties.

      It is expected that the Depositor will be designated as (or the
attorney-in-fact for) the tax matters partner in the related Trust Agreement
and, as such, will be responsible for representing the Certificateholders in any
dispute with the IRS. The Code provides for administrative examination of a
partnership as if the partnership was a separate and distinct taxpayer.
Generally, the statute of limitations for partnership items does not expire
before three years 


                                       58
<PAGE>   137

after the date on which the partnership information return is filed. Any adverse
determination following an audit of the return of the Trust Fund by the
appropriate taxing authorities could result in an adjustment of the returns of
the Certificateholders, and, under certain circumstances, a Certificateholder
may be precluded from separately litigating a proposed adjustment to the items
of the Trust Fund. An adjustment could also result in an audit of a
Certificateholder's returns and adjustments of items not related to the income
and losses of the Trust Fund.

      If and to the extent that the recognition of a Certificateholder's
distributive share of the partnership's losses reduces the Certificateholder's
adjusted tax basis in its Certificate below zero, the recognition of such losses
by the Certificateholder will be deferred until such time as the recognition of
such losses will not reduce its basis below zero. To the extent that the
partnership's cash distributions (or constructive cash distributions, as
described above) reduce a Certificateholder's adjusted tax basis in its
Certificate below zero, such distributions will constitute income to such holder
and will be treated as gain derived from the sale or exchange of the holder's
interest in the partnership.

      Tax Consequences to Foreign Certificateholders. Under the terms of the
Trust Agreement, the Certificates may not be acquired by or for the account of
an individual or entity that is not a U.S. person as defined in Section
7701(a)(30) of the Code, and any transfer of a Certificate to a person that is
not a U.S. person shall be void.

                            STATE TAX CONSIDERATIONS

      In addition to the federal income tax consequences described in "Certain
Federal Income Tax Considerations," potential investors should consider the
state and local income tax consequences of the acquisition, ownership, and
disposition of the Securities. State and local income tax law may differ
substantially from the corresponding federal law, and this discussion does not
purport to describe any aspect of the income tax laws of any state or locality.
Therefore, potential investors should consult their own tax advisors with
respect to the various state and local tax consequences of an investment in the
Securities. 

                              ERISA CONSIDERATIONS

      The Employee Retirement Income Security Act of 1974, as amended ("ERISA")
and Section 4975 of the Code impose certain restrictions on employee benefit
plans subject to ERISA and on plans and other arrangements subject to Section
4975 of the Code ("Plans"), and on persons who are parties in interest or
disqualified persons ("parties in interest") with respect to such Plans. Certain
employee benefit plans, such as governmental plans and church plans (if no
election has been made under Section 410(d) of the Code), are not subject to the
restrictions of ERISA or Section 4975 of the Code , and assets of such plans may
be invested in the Securities without regard to the ERISA considerations
described below, subject to other applicable federal and state law. However, any
such governmental or church plan which is qualified under Section 401(a) of the
Code and exempt from taxation under Section 501(a) of the Code is subject to the
prohibited transaction rules set forth in Section 503 of the Code.

      Investments by most 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.

      Section 406 of ERISA prohibits parties in interest with respect to a Plan
from engaging in certain transactions ("prohibited transactions") involving a
Plan and its assets unless a statutory or administrative exemption applies to
the transaction. Section 4975 of the Code imposes certain excise taxes (or, in
some cases, a civil penalty may be assessed pursuant to Section 502(i) of ERISA)
on parties in interest which engage in nonexempt prohibited transactions.

      The United States Department of Labor ("DOL") has issued a final
regulation (29 C.F.R. Section 2510.3-101) containing rules for determining what
constitutes the assets of a Plan. This regulation provides that, as a general
rule, the underlying assets and properties of corporations, partnerships, trusts
and certain other entities in which a Plan makes an investment in an "equity
interest" will be deemed, for purposes of ERISA and Section 4975 of the Code to
be assets of the Plan ("plan assets") unless certain exceptions apply.

      Under the terms of the DOL regulation, the Trust Fund may be deemed to
hold plan assets by reason of a Plan's investment in a Security; such plan
assets would include an undivided interest in the Mortgage Loans and any other
assets held by the Trust Fund. In such an event, persons providing services with
respect to the assets of the Trust Fund may be parties in interest, subject to
the fiduciary responsibility provisions of ERISA, including the 


                                       59
<PAGE>   138

prohibited transaction provisions of Section 406 of ERISA and Section 4975 of
the Code, with respect to transactions involving such assets unless such
transactions are subject to a statutory or administrative exemption.

      One such exception applies if the interest acquired by a Plan is treated
as indebtedness under applicable local law and has no substantial equity
features. Generally, a profits interest in a partnership, an undivided ownership
interest in Mortgaged Property and a beneficial ownership interest in a trust
are deemed to be "equity interests" under the DOL regulation. If Notes of a
particular Series were deemed to be indebtedness under applicable local law
without any substantial equity features, an investing Plan's assets would
include such Notes, but not, by reason of the Plan's investment, the underlying
assets of the Trust Fund.

      Another such exception applies if the class of equity interests in
question is: (i) "widely held" (held by 100 or more investors who are
independent of the Depositor and each other); (ii) freely transferable; and
(iii) sold as part of an offering pursuant to (A) an effective registration
statement under the Securities Act of 1933, and then subsequently registered
under the Securities Exchange Act of 1934 or (B) an effective registration
statement under Section 12(b) or 12(g) of the Securities Exchange Act of 1934
("Publicly Offered Securities"). In addition, the DOL regulation provides that
if at all times more than 75% of the value of each class of equity interests in
the Trust Fund are held by investors other than benefit plan investors (which is
defined as including Plans, government, church and foreign plans and individual
retirement accounts), the investing Plan's assets will not include any of the
underlying assets of the Depositor or the Trust Fund.

      An additional exemption may also be available. The DOL has granted to many
underwriters substantially similar administrative exemptions from certain of the
prohibited transaction rules of ERISA and Section 4975 of the Code with respect
to the initial purchase, the holding and the subsequent resale by Plans of
securities representing interests in asset-backed pass-through trusts that
consist of certain receivables, loans and other obligations that meet the
conditions and requirements of the exemption. These securities may include the
Certificates of a Series, and depending upon the particular characteristics of a
Series, may include the Notes. The obligations covered by such exemptions
include obligations such as the Mortgage Loans. The exemptions may apply to the
acquisition, holding and resale of the Securities by a Plan, provided that
certain conditions (certain of which are described below) are met.

      Among the conditions which must be satisfied for the exemptions to apply
are the following:

            (i) The acquisition of the Securities by a Plan is on terms
      (including the price for the Securities) that are at least as favorable to
      the Plan as they would be in an arm's-length transaction with an unrelated
      party;

            (ii) The rights and interests evidenced by the Securities acquired
      by the Plan are not subordinated to the rights and interests evidenced by
      other securities of the Trust Fund;

            (iii) The Securities acquired by the Plan have received a rating at
      the time of such acquisition that is in one of the three highest generic
      rating categories from either Standard & Poor's Ratings Services
      ("Standard & Poor's"), Moody's Investors Service, Inc. ("Moody's"), Duff &
      Phelps Credit Rating Co. ("D&P") or Fitch IBCA, Inc. ("Fitch");

            (iv) The sum of all payments made to the underwriter in connection
      with the distribution of the Securities represents not more than
      reasonable compensation for underwriting the Securities. The sum of all
      payments made to and retained by the Seller pursuant to the sale of the
      obligations to the Trust represents not more than the fair market value of
      such obligations. The sum of all payments made to and retained by the
      Servicer represents not more than reasonable compensation for the
      Servicer's services under the related servicing agreement and
      reimbursement of the Servicer's reasonable expenses in connection
      therewith;

            (v) The Trustee must not be an affiliate of any other member of the
      Restricted Group (as defined below); and

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

      In order for the exemptions to apply, the Trust Fund also must meet the
following requirements:

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


                                       60
<PAGE>   139

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

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

      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 securities 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 Securities, at least fifty (50) percent of each Class of
Securities in which Plans have invested is acquired by persons independent of
the Restricted Group and at least fifty (50) 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 (5) percent
or less of the fair market value of the obligations contained in the trust;
(iii) the Plan's investment in Securities does not exceed twenty-five (25)
percent of all of the Securities issued by the Trust Fund outstanding after the
acquisition; and (iv) no more than twenty-five (25) percent of the assets of the
Plan are invested in securities representing an interest in one or more trusts
containing assets sold or serviced by the same entity. The Exemption does not
apply to Plans sponsored by the Depositor, the underwriters of the Securities,
the Trustee, the Servicer, any obligor with respect to obligations included in a
Trust Fund constituting more than five (5) percent of the aggregate unamortized
principal balance of the assets in a Trust Fund, or any affiliate of such
parties (the "Restricted Group").

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

                                LEGAL INVESTMENT

      Unless otherwise specified in the related Prospectus Supplement, the
Securities will not constitute "mortgage-related securities" within the meaning
of SMMEA. Accordingly, investors whose investment authority is subject to legal
restrictions should consult their own legal advisors to determine whether and to
what extent the Securities constitute legal investments for them. 

                              PLAN OF DISTRIBUTION

      The Depositor may offer each Series of Securities through one or more

Item 15. Indemnification of Directors and Officers.

      Neither any Pooling and Servicing Agreement to be entered into among any
of the trusts to be formed, the Registrant, Bank One, N.A. as Servicer and the
Trustee hereunder (the "Pooling and Servicing Agreement"), relating to the
securities being registered, will provide for the indemnification of any
director, officer, employee or agents of the Registrant or Bank One, N.A., in
its capacity as Servicer thereunder, or in connection with any loss, liability
or expense incurred in connection with legal action relating to the Pooling and
Servicing Agreement and the securities issued pursuant thereto or related
thereto. The Pooling and Servicing Agreement will provide that any director,
officer, employee or agent of Bank One, N.A., in its capacity as Servicer
thereunder, may rely on any document of any kind which it in good faith
reasonably believes to be genuine and to have been adopted or signed by the
proper authorities respecting any matters arising thereunder.

      Section 1701.13(E) of the Ohio General Corporation Law sets forth
provisions which define the extent which a corporation may indemnify directors,
officers and employees. Those provisions have been adopted by the Registrant in
Article VI of Registrant's Code of Regulations, which provides as follows:

            The Corporation may indemnify any director or officer, any former
      director or officer of the Corporation and any person who is or has served
      at the request of the Corporation as a director, officer or trustee of any
      other corporation, partnership, joint venture, trust or other enterprise
      (and his heirs, executors and administrators) against expenses, including
      attorneys' fees, judgments, fines and amounts paid in settlement, actually
      and reasonably incurred by him by reason of the fact that he is or was
      such director, officer or trustee in connection with any threatened,
      pending or completed action, suit or proceeding, whether civil, criminal,
      administrative or investigative, to the full extent and according to the
      procedures and requirements set forth in the Ohio General Corporation Law
      as the same may be in effect from time to time. The indemnification
      provided for herein shall not be deemed to restrict the right of the
      Corporation to (i) indemnify employees, agents and others permitted by
      such Law, (ii) purchase and maintain insurance or provide similar
      protection on behalf of directors, officers or such other persons against
      liabilities asserted against them or expenses incurred by them
<PAGE>   146

      arising out of their service to the Corporation as contemplated herein,
      and (iii) enter into agreements with such directors, officers, employees,
      agents or others indemnifying them against any and all liabilities (or
      such lesser indemnification as may be provided in such agreement) asserted
      against them or incurred by them arising out of their service to the
      Corporation as contemplated herein.

      The Registrant's parent, BANC ONE CORPORATION, has entered into
indemnification agreements with certain directors and executive officers of the
Registrant that provide for indemnification unless the indemnitee's conduct is
finally adjudged by a court be knowingly fraudulent, deliberately dishonest or
willful misconduct.

      (ii) To reflect in the prospectus any facts or event arising after the
      effective date of this registration statement (or the most recent
      post-effective amendment thereof) which, individually or in the aggregate,
      represent a fundamental change in the information set forth in this
      registration statement. Notwithstanding the foregoing, any increase or
      decrease in volume of securities offered (if the total dollar value of
      securities offered would not exceed that which was registered) and any
      deviation from the low or high and of the estimated maximum offering range
      may be reflected in the form of prospectus filed with the Commission
      pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
      price represent no more than 20 percent change in the maximum aggregate
      offering price set forth in the "Calculation of Registration Fee" table in
      the effective registration statement;

      (iii) To include any material information with respect to the plan of
      distribution not previously disclosed in this registration statement or
      any material change to such information in this registration statement;
      provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply
      if the information required to be included in a post-effective amendment
      by those paragraphs is contained in periodic reports filed by the
      Registrants pursuant to Section 13 or 15(d) of the Securities Exchange Act
      of 1934 that are incorporated by reference in this Registration Statement.

      (2) That, for the purpose of determining any liability under the
Securities Act of 1933, each such post- effective amendment shall be deemed to
be a new registration statement relating to the securities offered therein, and
the offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof.

      (3) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.

      (b) Undertaking in respect of documents subsequently filed that are
incorporated by reference:

      The Registrant hereby undertakes that, for purposes of determining any
liability under the Securities Act of 1933, each filing of the Registrant's
annual report pursuant to Section 13(a) or Section 15(d) of the Securities
Exchange Act of 1934 that is incorporated by reference in the Registration
Statement shall be deemed a new registration statement relating to the
securities offered therein, and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.

      (c) Undertaking in respect of indemnification

      Insofar as indemnification for liabilities arising under the Securities
Act of 1933 (the "Act") may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the foregoing provisions, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

                  powers permitted to corporations organized under the General

                  or convenient for the accomplishment of the


                                      -2-
<PAGE>   4

                  above mentioned business and purposes.

FOURTH.     The number of shares which the Corporation is authorized to have
            outstanding is five hundred (500) shares of common stock, all of
            which shall be without par value.

FIFTH.      The amount of stated capital with which the Corporation shall begin
            business is Five Hundred Dollars ($500.00).

SIXTH.      (a)   The affairs of the Corporation shall be managed by a board of
                  directors consisting of three members. At all times on and
                  after the date of issuance of Securities by any Trust, there
                  shall be at least one director of the Corporation (the
                  "Outside Director") who is not a director, officer or employee
                  of, or direct or indirect beneficial owner of 10% or more of
                  the voting securities of, or member of the immediate family of
                  any such director, officer, employee or beneficial owner of
                  the Corporation's parent, BANC ONE CORPORATION ("BANC ONE"),
                  or any corporate affiliate of BANC ONE. Notwithstanding the
                  foregoing, the Outside Director may be a director of one other
                  corporation that is an affiliate of BANC ONE, provided such
                  corporation is formed with purposes limited to those similar
                  to the purposes of the Corporation. For the purposes of the
                  foregoing, the "affiliate" of an entity is an entity
                  controlling, controlled by or under common control with such
                  entity. Should any Outside Director resign, die, become
                  disabled or incapacitated, or be prevented from acting, the
                  affairs of the Corporation shall and may be managed by the
                  remaining directors, who shall promptly replace the
                  aforementioned Outside Director with a person meeting the
                  requirements set forth above. When voting on matters subject
                  to the vote of the Corporation's Board of Directors, including
                  those matters specified in this Article Sixth and in Article
                  Seventh hereof, notwithstanding that the Corporation is not
                  then insolvent, the Outside Director shall take into account
                  the interests of the creditors of the Corporation as well as
                  the interests of the Corporation.

            (b)   The Corporation shall maintain a principal office through
                  which its business shall be conducted, which office may be
                  separately denoted space at the offices of BANC ONE.

            (c)   The Corporation shall maintain corporate records and books of
                  account and shall not commingle its corporate records and
                  books of account with the corporate records and books of
                  account of BANC ONE.

            (d)   The Board of Directors of the Corporation shall hold
                  appropriate meetings to


                                      -3-
<PAGE>   5

                  authorize all of its corporate actions. Regular meetings of
                  the Board of Directors shall be held not less frequently than
                  three times per annum.

            (e)   The funds and other assets of the Corporation shall not be
                  commingled with those of any other corporation.

            (f)   The Corporation shall pay its own expenses and shall not hold
                  itself out as being liable for the debts of any other party.

            (g)   The Corporation shall not form, or cause to be formed, any
                  subsidiaries.

            (h)   The Corporation shall act solely in its corporate name and
                  through its duly authorized officers or agents in the conduct
                  of its business, and shall conduct its business so as not to
                  mislead others as to the identity of the entity with which
                  they are concerned.

            (I)   Meetings of the shareholders of the Corporation shall be held
                  not less frequently than one time per annum.

            (j)   The Corporation shall operate in such a manner that it would
                  not be substantively consolidated in the trust estate of any
                  other entity.

SEVENTH.    Notwithstanding any other provision of these Articles of

the annual meeting for election of Directors is not held on the date designated
therefor, the Directors shall cause the meeting to be held as soon thereafter as
convenient.

SECTION 1.02. SPECIAL MEETINGS. Special meetings of the shareholders for any
purpose(s), may be called at any time by the Chairman, the President, the Board
of Directors or any two members thereof. Special meetings of shareholders shall

business may be transacted at any such meeting except that referred to in such
notice or in a supplemental notice given in compliance with this Code of
Regulations.

SECTION 1.03. NOTICE OF MEETING. Whenever shareholders are required or permitted
to take any action at a meeting, a written notice stating the place, date, hour
and purpose(s) of the shareholders' meeting shall be given to the shareholders.
Said notice shall be given by or under the direction of the Secretary of the
Corporation or such other Officer of the Corporation as is designated by the
Board of Directors. Such written notice of any meeting shall be given,
personally or by mail, postage prepaid, not less than ten nor more than fifty
days before the date of the meeting, to each shareholder entitled to vote at
such meeting. If mailed, such notice shall be addressed to the shareholder at
his address as it appears on the records of the Corporation. Any shareholder may
waive any notice required to be given by law, the Articles of Incorporation, or
this Code of Regulations.

When a meeting is adjourned to another time or place, it shall not be necessary
to give any notice of the adjourned meeting if the time and place to which the
meeting is adjourned are announced at the meeting at which the adjournment is
taken. Any business may be transacted at the adjourned meeting which might have

SECTION 1.04. QUORUM. Except as otherwise required by law, the Articles of
Incorporation or this Code of Regulations, the holders of record of a majority
of the issued and outstanding shares of the Corporation entitled to vote shall
constitute a quorum at a meeting of shareholders for the transaction of any
business. When a quorum is once present to organize a meeting, it is not broken
by the subsequent withdrawal of any shareholders. The shareholders present may
adjourn the meeting despite the absence of a quorum. At any such adjourned
meeting at which the requisite amount of voting stock shall be represented, any
business may be transacted which might have been transacted at the meeting as
originally noticed.

SECTION 1.05. RECORD DATE. In order that the Corporation may determine the
shareholders entitled to notice of or to vote at any meeting of shareholders or
any adjournment thereof, or to express consent to corporate action in writing
without a meeting, or entitled to receive payment of any dividend or other
distribution or allotment of any rights, or entitled to exercise any rights in
respect of any change, conversion or exchange of stock or for the purpose of any
other lawful action, the Board of Directors may fix, in advance, a record date
which shall not be more than sixty nor less than ten days before the date of
such meeting nor more than sixty days prior to any other action.

SECTION 1.06. PROXIES. Each shareholder entitled to vote at a shareholders'
meeting, or to express consent or dissent to corporate action in writing without
a meeting, may authorize another person or persons, including a partnership or
corporation, to act for him by proxy. Each such proxy shall be dated and if not
dated by the shareholder, shall be dated as of the date of receipt thereof. No
such proxy shall be valid after the final adjournment of any meeting for which
it shall have been given. Every proxy shall be revocable at the pleasure of the
shareholder executing it in accordance with the provisions of the General
Corporation Law of Ohio.

SECTION 1.07. SELECTION AND DUTIES OF JUDGES. The Board of Directors, in advance
of any shareholders' meeting, may appoint one or more judges to act at the
meeting or any adjournment thereof. If judges are not so appointed, the person
presiding at a shareholders' meeting may and on the request of any shareholder
entitled to vote thereat, or his proxy, shall appoint one or more judges. In
case any person appointed fails to appear or to act, the vacancy may be filled
by appointment made by the Board in advance of the meeting or at the meeting by
the person presiding thereat. If there are three or more judges, the decision,
act or certificate of a majority of them shall be effective in all respects as
the decision, act or certificate of all.

The judge(s) shall determine the number of shares outstanding and the voting
power of each, the shares represented at the meeting, the existence of a quorum,
the authenticity, validity and effect of proxies, receive votes, ballots,
consents, waivers or releases; hear and determine all challenges and questions
arising in connection with the right to vote, count and tabulate all votes,
consents, waivers and releases; determine and announce the result and do such
acts as are proper to conduct the election or vote with fairness to all
shareholders. On the request of the person presiding at the meeting or any
shareholder entitled to vote thereat, the judge(s) shall make a 


                                      -2-
<PAGE>   3

report in writing of any challenge, question or matter determined and execute a
certificate of any fact found. Any report or certificate made shall be prima
facie evidence of the facts stated therein and of the vote as certified by the
judge(s). Unless appointed as above provided in this section, the judge(s) shall
be dispensed with at all meetings of shareholders.

SECTION 1.08. VOTE OF SHAREHOLDERS. Every shareholder of record, as of the
record date fixed by the Board of Directors, shall, with respect to each matter
submitted to vote at a shareholders' meeting, be entitled to one vote for every
share of capital stock standing in his name on the record of shareholders.
Directors shall be elected by a plurality of the votes cast by the holders of
the outstanding shares of the Corporation which are represented at the meeting
and entitled to vote in the election. Whenever any corporate action, other than
the election of Directors, is to be taken by vote of the shareholders, such
corporate action shall, except as otherwise required by law, the Articles of
Incorporation or this Code of Regulations, be authorized by the affirmative
votes of the holders of record of a majority of the votes cast at a meeting of
shareholders by the holders of shares entitled to vote thereon.

SECTION 1.09. PRESIDING OFFICER. Meetings of the shareholders shall be presided
over by the Chairman of the Board, if any, or if not present or there is no one
filling that office by the President of the Corporation, or such other member of
the Board as is designated by the Board. The Chairman, if any, and the President
of the Corporation shall be members of the Board of Directors. The Secretary or
such other officer or director as is designated by the Board of the Corporation
shall record all the proceedings of the meetings of the shareholders and he
shall act as Secretary of all meetings of the shareholders. In the absence of
the Secretary or such other officer or director so designated, the presiding
officer shall appoint another officer or a shareholder of the Corporation to act
as Secretary of the meeting.

SECTION 2.01. MANAGEMENT OF CORPORATION. The business of the Corporation shall
be managed by its Board of Directors, each member of which shall have the
qualifications prescribed by law, and shall have such further qualifications
relating to age, business affiliation and employment by the Corporation as are
from time to time adopted by the Board of Directors.

SECTION 2.02. NUMBER AND ELECTION. Unless otherwise fixed by the Articles of
Incorporation, the number of members of the Board of Directors shall be
determined from time to time by the vote of the holders of a majority of the
shares entitled to vote thereon at any annual meeting or special meeting called
for the purpose of electing directors and, when so fixed, such number shall
continue to be the authorized number of members of the Board of Directors until
changed by the shareholders by vote as aforesaid. If the annual meeting for
election of Directors is not held on the date designated therefor, the Directors
shall cause the meeting to be held as soon thereafter as convenient.

majority of the members of the Board of Directors then in office, although such
majority is less than a quorum, or by a sole remaining Director.

SECTION 2.05. QUORUM. A majority of the total authorized number of Directors
shall constitute a quorum for the transaction of business at a meeting of the
Directors. The act of a majority of the Directors present at a meeting at which
a quorum is present shall be the act of the Board except as otherwise provided
by law, the Articles of Incorporation or this Code of Regulations. A majority of
the Directors present, whether or not a quorum is present, may adjourn a meeting
of the Directors to another time and place. Notice of any adjournment need not
be given if such time and place are announced at the meeting.

SECTION 2.06. ANNUAL MEETING. Immediately following the adjournment of the
annual meeting of shareholders, the newly-elected Board of Directors, if a
quorum thereof be present, shall meet for the purpose of organization, the
election of officers and the transaction of any other business. Notice of such
meeting need not be given. If for any reason such organizational meeting is not
held at such time, a special meeting for such purpose shall be held at such
other time and place as is determined by the Board and notice thereof shall not
be necessary.

SECTION 2.07. REGULAR MEETINGS. Regular meetings of the Board of Directors shall
be held, without notice, on such date and at such hour and place as shall from
time to time be fixed by the Board and no notice thereof shall be necessary.
When the date fixed is a legal holiday, the regular meeting shall be held on the
next succeeding business day or on such other day as the Board specifically
designates at the next preceding Board meeting.

SECTION 2.08. SPECIAL MEETINGS. Special meetings of the Board of Directors may

special meeting of the Directors, stating the date, hour and place of the
meeting, shall be given to each Director, by personal communication either over
the telephone or otherwise, not later than the second day prior to the meeting,
or by mailed letter deposited in the United States mail with postage thereon
prepaid not later than the seventh day prior to the meeting. Notices of special
meetings of the Board of Directors and waivers thereof need not state the

of Directors may be transacted at any meeting, whether or not stated in the

receiving compensation therefor.

SECTION 2.11. COMMITTEES. The Board of Directors, by resolution adopted by a
majority of the Board, may designate from among its members an Executive
Committee and other committees, both standing and special, each consisting of

Law of Ohio, shall have and may exercise the powers of the Board of Directors in
the management of the business and affairs of the Corporation.

Secretary, the Treasurer, and Vice Presidents of the Corporation and fix their
salaries subject to approval of the Board. Any two or more offices may be held

to them from time to time by the President.

Corporation upon a certificate may be facsimiles if the certificate is
countersigned by a transfer agent or by a registrar other than the Corporation
itself or its employee. In case any officer who has signed or whose facsimile

canceled when the new certificate shall be issued.

SECTION 4.03. REGISTERED HOLDERS. The Corporation shall be entitled to treat and
shall be protected in treating persons in whose names shares or any warrants,
rights or options stand on the records of shareholders, warrant holders, right
holders or option holders, as the case may be, as the owners thereof for all
purposes and shall not be bound to recognize any equitable or other claim to, or
interest in, any such share, warrant, right or option on the part of any other
person, whether or not the Corporation shall have notice hereof.

SECTION 4.04. NEW CERTIFICATES. The Corporation may issue a new certificate of
stock in the place of any certificate theretofore issued by it, alleged to have
been lost, stolen or 


                                      -6-
<PAGE>   7

destroyed, and the Corporation may require the owner of the lost, stolen or
destroyed certificate, or his legal representative, to give the Corporation a
bond sufficient to indemnify the Corporation and any transfer agent and/or
registrar against any claim that may be made against it or them on account of
the alleged loss, theft or destruction of any such certificate or the issuance
of such new certificate. A new certificate may be issued without requiring any
bond when it is proper to do so.

repealed at any annual meeting of shareholders or at any special meeting called
for that purpose by the affirmative votes of the holders of record of a majority
of the shares entitled to vote on

such proposal in person or by proxy, or without a meeting by the two-thirds of

                                   ARTICLE VI
                    INDEMNIFICATION OF DIRECTORS AND OFFICERS

SECTION 6.01. INDEMNIFICATION. The Corporation may indemnify any director or
officer, any former director or officer of the Corporation and any person who is
or has served at the request of the Corporation as a director, officer or
trustee of another corporation, partnership, joint venture, trust or other
enterprise (and his heirs, executors and administrators) against expenses,
including attorneys' fees, judgments, fines and amounts paid in settlement,
actually and reasonably incurred by him by reason of the fact that he is or was
such director, officer or trustee in connection with any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative, to the full extent and according to the procedures and
requirements set forth in the Ohio General Corporation Law as the same may be in
effect from time to time. The indemnification provided for herein shall not be
deemed to restrict the right of the Corporation to (i) indemnify employees,
agents and others as permitted by such Law, (ii) purchase and maintain insurance
or provide similar protection on behalf of directors, officers or such other
persons against liabilities asserted against them or expenses incurred by them
out of their service to the Corporation as contemplated herein, and (iii) enter

indemnifying them against any and all liabilities (or such lesser
indemnification as may be provided in such agreements) asserted against them or
incurred by them arising out of their service to the Corporation as contemplated
herein.

Files, which possession will, subject to the terms hereof, be maintained by the
Servicer as custodian and bailee of the Trustee).

      (b) In connection with such transfer and assignment by the Depositor, the
Servicer acknowledges that it is holding as custodian and bailee for the Trustee
the following documents or instruments (the "Related Documents") with respect to
each Mortgage Loan:

            (i) the original Mortgage Note;


                                       18
<PAGE>   23

            (ii) the original recorded Mortgage or, if, in connection with any
      Mortgage Loan, the original recorded Mortgage with evidence of recording
      thereon cannot be delivered on or prior to the Closing Date because of a
      delay caused by the public recording office where such original Mortgage
      has been delivered for recordation or because such original Mortgage has
      been lost, the Seller, at the direction of the Depositor, shall deliver or
      cause to be delivered to the Custodian, as agent for the Trustee, a true
      and correct copy of such Mortgage, together with an officer's Certificate
      of the Seller stating that such original Mortgage has been dispatched to
      the appropriate public recording official or has been lost;

            (iii) if applicable, the original intervening assignments, if any
      ("Intervening Assignments"), with evidence of recording thereon, showing a
      complete chain of title to the Mortgage from the originator to the
      Depositor or, if any such original Intervening Assignment has not been
      returned from the applicable recording office or has been lost, a true and
      correct copy thereof, together with an Officer's Certificate of the Seller
      stating that such original Intervening Assignment has been dispatched to
      the appropriate public recording official for recordation or has been
      lost;

            (iv) for each Mortgage Loan either a title insurance policy or a
      title search or guaranty of title with respect to the related Mortgaged
      Property to the extent in possession of the Seller or its Affiliates;

            (v) the original of any guaranty executed in connection with the
      Mortgage Note;

            (vi) the original of each assumption, modification, consolidation or
      substitution agreement, if any, relating to the Mortgage Loan; and

            (vii) any security agreement, chattel mortgage or equivalent
      instrument executed in connection with the Mortgage; and

            (viii) within 90 days of a Document Preparation Trigger, the
      original Mortgage Note, endorsed in blank and an original Assignment of
      Mortgage endorsed in blank prepared in recordable form, in each case as
      required by Section 2.01(b).

provided, however, that as to any Mortgage Loan, if (a) as evidenced by an
opinion of Counsel delivered to and in form and substance satisfactory to the
Trustee and the Credit Enhancer, (x) an optical image or other representation of
the related documents specified in clauses (i) through (viii) above are
enforceable in the relevant jurisdictions to the same extent as the original of
such document and (y) such optical image or other representation does not impair
the ability of an owner of such Mortgage Loan to transfer its interest in such
Mortgage Loan, and (b) the retention of such documents in such format will not
result in a reduction in the then current rating of the Investor Certificates,
without regard to the Policy, such optical image or other representation may be
held by the Servicer, as custodian for the Trustee or assignee in lieu of the
physical documents specified above.

      [The Seller hereby confirms to the Trustee that it has caused the portions
of the Electronic Ledgers relating to the Mortgage Loans to be clearly and
unambiguously marked, and


                                       19
<PAGE>   24

has made the appropriate entries in its general accounting records, to indicate
that such Mortgage Loans have been transferred to the Trust at the direction of
the Depositor.] The Servicer hereby confirms to the Trustee that it has clearly
and unambiguously made appropriate entries in its general accounting records
indicating that such Mortgage Loans constitute part of the Trust and are
serviced by it on behalf of the Trust in accordance with the terms hereof.

      [The Seller and] Servicer agree not to notify the obligors on the Mortgage
Loans of the transfer of the Mortgage Loans to the Trust, unless required by the
terms of the Mortgage Loans or applicable law.

      It is the express intent of the parties hereto that the conveyance of the
Mortgage Loans by the Depositor to the Trustee as provided in this Agreement be,
and be construed as, a sale of all of the Depositor's right, title and interest
in the Mortgage Loans by the Depositor to the Trustee. It is, further, not the
intention of the parties that such conveyance be deemed a pledge of the Mortgage
Loans by the Depositor to the Trustee to secure a debt or other obligation of
the Depositor. However, in the event, that notwithstanding the intent of the
parties, the Mortgage Loans are held to be property of the Depositor, or if for
any reason this Agreement is held or deemed to create a security interest in the
Mortgage Loans, then, (a) this Agreement shall also be deemed to be a security
agreement within the meaning of Articles 8 and 9 of the Uniform Commercial Code
in effect in the applicable state; (b) the conveyance provided for in this
Agreement shall be deemed to be a grant by the Depositor to the Trustee of a
security interest in and to all of the Depositor's right, title, and interest,
whether now owned or hereafter acquired, in and to:

                  (I) All accounts, contract rights, general intangibles,
            chattel paper, instruments, documents, money, deposit accounts,
            certificates of deposit, goods, letters of credit, advices of
            credit, certificated securities and uncertificated securities
            consisting of, arising from or relating to any of the property
            described in (A) through (D) below: (A) each Mortgage Loan,
            including (a) the Mortgage Note and the related Mortgage and (b) its
            Asset Balance and all Additional Balances and all collections in
            respect thereof received on or after the Cut-Off Date, identified on
            the Mortgage Loan Schedule as defined herein, including all Eligible
            Substitute Mortgage Loans, (B) property that secured a Mortgage Loan
            that is acquired by foreclosure or deed in lieu of foreclosure; (C)
            the Purchase Agreement, (D) any hazard insurance policies in respect
            of the Mortgage Loans; and (E) the Spread Account; and

                  (II) All proceeds of the collateral described in (I).

(c) the possession by the Trustee or its designee of the Mortgage Notes, the
Mortgages and such other goods, letters of credit, advices of credit,
instruments, money, documents, chattel paper or certificated securities shall be
deemed to be "possession by the secured party," or possession by a purchaser or
a person designated by him or her, for purposes of perfecting the security
interest pursuant to the Uniform Commercial Code (including, without limitation,
Sections 9-305, 8-313 or 8-321 thereof) as in force in the relevant
jurisdiction; and (d) notifications to persons holding such property, and
acknowledgments, receipts or confirmations from persons holding such property,
shall be deemed to be notifications to, or acknowledgments,


                                       20
<PAGE>   25

receipts or confirmations from, financial intermediaries, bailees or agents (as
applicable) of the Trustee or its designee for the purpose of perfecting such
security interest under applicable law. Subject to the provisions herein
permitting the Servicer (i) to retain possession of the Mortgage Files and (ii)
to commingle amounts collected with respect to the Mortgage Loans with other
general collections of the Servicer, the Depositor and the Trustee at the
direction of the Depositor to the extent consistent with this Agreement, shall
take such actions as may be necessary to ensure that, if this Agreement were
deemed to create a security interest in the Mortgage Loans and the proceeds
thereof, such security interest would be deemed to be a perfected security
interest of first priority under applicable law and will be maintained as such
throughout the term of the Agreement. In connection herewith, the Trustee shall
have all of the rights and remedies of a secured party and creditor under the
Uniform Commercial Code as in force in the relevant jurisdiction.

      Except as hereinafter provided, the Servicer shall be entitled to maintain
possession of all of the foregoing documents and instruments and shall not be
required to deliver any of them to the Trustee. If possession of any of such
documents or instruments is required by any Person (including the Trustee)
acting as successor servicer pursuant to Section 7.04 or 8.02 in order to carry
out the duties of Servicer hereunder, then such successor shall be entitled to
request delivery of such documents or instruments by and at the expense of the
Servicer and to retain such documents or instruments for servicing purposes;
provided that the Trustee or such servicers shall maintain such documents at
such offices as may be required by any regulatory body having jurisdiction over
such Mortgage Loans.

      The Servicer's right to maintain possession of the documents enumerated
above shall continue so long as the long term unsecured debt of Bank One, N.A.,
is assigned ratings of at least "___" by ________ and "____" by _________. At
such time as the condition specified in the preceding sentence is not satisfied,
as promptly as practicable but in no event more than 90 days in the case of
clause (i) below and 60 days in the case of clause (ii) below following the
occurrence of such event (a "Delivery Event"), the Servicer shall, at its
expense, (i) either (x) record an Assignment of Mortgage in favor of the Trustee
(which may be a blanket assignment if permitted by applicable law) in the
appropriate real property or other records or (y) deliver to the Trustee the
assignment of such Mortgage in favor of the Trustee in form for recordation,
together with an opinion of Counsel addressed to the Trustee and the Credit
Enhancer to the effect that recording is not required to protect the Trustee's
right, title and interest in and to the related Mortgage Loan or, in case a
court should recharacterize the sale of the Mortgage Loans as a financing, to
perfect a first priority security interest in favor of the Trustee in the
related Mortgage Loan, which Opinion of Counsel also shall be reasonably
acceptable to each of the Rating Agencies (as evidenced in writing) and the
Credit Enhancer, and (ii) unless an opinion of Counsel, reasonably acceptable to
the Trustee, the Rating Agencies (as evidenced in writing) and the Credit
Enhancer, is delivered to the Trustee and the Credit Enhancer to the effect that
delivery of the Mortgage Files is not necessary to protect the Trustee's right,
title and interest in the related Mortgage Loans and that the lack of delivery
will not result in a reduction in the then current rating of the Investor
Certificates, without regard to the Policy, deliver the related Mortgage Files
to the Trustee or to a custodian located in the State of New York appointed by
the Trustee and acceptable to the Rating Agencies and the Credit Enhancer to be
held by the Custodian on behalf of the Trustee in trust, upon the terms herein
set forth, for the use and benefit of all present and future Certificateholders
and the Custodian on behalf of the Trustee


                                       21
<PAGE>   26

shall retain possession thereof except to the extent the Servicer requires any
Mortgage Files for normal servicing as contemplated by Section 3.07. The Trustee
is hereby appointed as the attorney-in-fact of the Servicer with the power to
prepare, execute and record Assignments of Mortgages in the event that the
Servicer fails to do so on a timely basis as provided in this paragraph.

      Within 90 days following delivery, if any, of the Mortgage Files to the
Trustee pursuant to the preceding paragraph, the Trustee shall review each such
Mortgage File to ascertain that all required documents set forth in this Section
2.01 have been executed and received, and that such documents relate to the
Mortgage Loans identified on the Mortgage Loan Schedule and in so doing the
Trustee may rely on the purported due execution and genuineness of any signature
thereon. If within such 90-day period the Trustee finds any document
constituting a part of a Mortgage File not to have been executed or received or
to be unrelated to the Mortgage Loans identified in said Mortgage Loan Schedule
or, if in the course of its review, the Trustee determines that such Mortgage
File is otherwise defective in any material respect, the Trustee shall promptly
upon the conclusion of its review notify the Seller and the Credit Enhancer, and
the Seller shall have a period of 90 days after such notice within which to
correct or cure any such defect.

      The Trustee shall have no responsibility for reviewing any Mortgage File
except as expressly provided in this Section 2.01. In reviewing any Mortgage
File pursuant to this Section, the Trustee shall have no responsibility for
determining whether any document is valid and binding, whether the text of any
assignment or endorsement is in proper or recordable form (except, if
applicable, to determine if the Trustee is the assignee or endorsee), whether
any document has been recorded in accordance with the requirements of any
applicable jurisdiction, or whether a blanket assignment is permitted in any
applicable jurisdiction, whether any Person executing any document is authorized
to do so or whether any signature thereon is genuine, but shall only be required
to determine whether a document has been executed, that it appears to be what it
purports to be, and, where applicable, that it purports to be recorded.

      (b) Within 90 days after an occurrence of a Document Preparation Trigger,
the Servicer shall prepare for each Mortgage Loan an endorsement in blank of the
original Mortgage Note, and an original Assignment of Mortgage in blank prepared
in recordable form.

      Section 2.02. Acceptance by Trustee; Retransfer of Mortgage Loans. (a) The
Trustee hereby acknowledges its receipt of the Policy and the Mortgage Loans,
and declares that the Trustee holds and will hold such instrument, and to the
extent that any documents are delivered to it pursuant to Section 2.01, will
hold such documents, and all amounts received by it thereunder and hereunder, in
trust, upon the terms herein set forth, for the use and benefit of all present
and future Certificateholders and the Credit Enhancer. If the time to cure any
defect in respect of any Mortgage Loan of which the Trustee has notified the
Seller and the Depositor following the review pursuant to Section 2.01 has
expired or if at any time any loss is suffered by the Trustee on behalf of the
Certificateholders or the Credit Enhancer, in respect of any Mortgage Loan as a
result of (i) a defect in any document constituting a part of its Mortgage File
or (ii) an Assignment of Mortgage to the Trustee not having been recorded as
required by Section 2.01, then on the next succeeding Business Day upon the
deposit to the Collection Account of the Transfer Deposit Amount, if any, and
upon satisfaction of the applicable


                                       22
<PAGE>   27

conditions described herein, all right, title and interest of the Trust in and
to such Mortgage Loan shall be deemed to be retransferred, reassigned and
otherwise reconveyed, without recourse, representation or warranty, to the
Seller on such Business Day and the Asset Balance of such Mortgage Loan shall be
deducted from the Pool Balance; provided, however, that interest accrued on the
Asset Balance of such Mortgage Loan to the end of the related Collection Period
shall be the property of the Trust. The Trustee shall determine if the reduction
of such Asset Balance from the Pool Balance in accordance with the preceding
sentence would cause the Transferor Principal Balance to be less than the
Minimum Transferor Interest ("Transfer Deficiency"), in which event the Trustee
shall deliver written notice of such deficiency to the Seller, and within five
Business Days after the Business Day of such retransfer the Seller shall either
(i) substitute an Eligible Substitute Mortgage Loan or (ii) deposit into the
Collection Account an amount (the "Transfer Deposit Amount") in immediately
available funds equal to the Transfer Deficiency or a combination of both (i)
and (ii) above. Such reduction or substitution and the actual payment of any
Transfer Deposit Amount, if any, shall be deemed to be payment in full for such
Mortgage Loan. Upon receipt of any Eligible Substitute Mortgage Loan or of
written notification signed by a Servicing Officer to the effect that the
Transfer Deposit Amount in respect of a Defective Mortgage Loan has been
deposited into the Collection Account or, if the Transferor Principal Balance is
not reduced below the Minimum Transferor Interest as a result of the deemed
retransfer of a Defective Mortgage Loan, then as promptly as practicable
following such deemed transfer, the Trustee shall execute such documents and
instruments of transfer presented by the Seller, in each case without recourse,
representation or warranty, and take such other actions as shall reasonably be
requested by the Seller to effect such transfer by the Trust of such Defective
Mortgage Loan pursuant to this Section. It is understood and agreed that the
obligation of the Seller to accept a transfer of a Defective Mortgage Loan and
to either convey an Eligible Substitute Mortgage Loan or to make a deposit of
any related Transfer Deposit Amount into the Collection Account shall constitute
the sole remedy respecting such defect available to Certificateholders, the
Trustee and the Credit Enhancer against the Seller.

      The Servicer, promptly following the transfer of a Defective Mortgage Loan
from or the transfer of an Eligible Substitute Mortgage Loan to the Trust
pursuant to this Section, shall amend the Mortgage Loan Schedule and make
appropriate entries in its general account records to reflect such transfer. The
Servicer shall, following such retransfer, appropriately mark its records to
indicate that it is no longer servicing such Mortgage Loan on behalf of the
Trust. The Seller, promptly following such transfer, shall appropriately mark
its Electronic Ledger and make appropriate entries in its general account
records to reflect such retransfer.

      Notwithstanding any other provision of this Section, a retransfer of a
Defective Mortgage Loan to the Seller pursuant to this Section that would cause
the Transferor Principal Balance to be less than the Minimum Transferor Interest
shall not occur if either the Seller fails to convey an Eligible Substitute
Mortgage Loan or to deposit into the Collection Account any related Transfer
Deposit Amount required by this Section with respect to the transfer of such
Defective Mortgage Loan.

      (b) As to any Eligible Substitute Mortgage Loan or Loans, the Seller
shall, if a Delivery Event has occurred, deliver to the Trustee with respect to
such Eligible Substitute Mortgage Loan or Loans such documents and agreements as
are required to be held by the Trustee in accordance with Section 2.01. For any
Collection Period during which the Seller


                                       23
<PAGE>   28

substitutes one or more Eligible Substitute Mortgage Loans, the Servicer shall
determine the Transfer Deposit Amount which amount shall be deposited by the
Seller in the Collection Account at the time of substitution. Any amounts
received in respect of the Eligible Substitute Mortgage Loan or Loans during the
Collection Period in which the circumstances giving rise to such substitution
occur shall not be a part of the Trust Fund and shall not be deposited by the
Servicer in the Collection Account. All amounts received by the Servicer during
the Collection Period in which the circumstances giving rise to such
substitution occur in respect of any Defective Mortgage Loan so removed by the
Trust Fund shall be deposited by the Servicer in the Collection Account. Upon
such substitution, the Eligible Substitute Mortgage Loan or Loans shall be
subject to the terms of this Agreement in all respects, and the Seller shall be
deemed to have made with respect to such Eligible Substitute Mortgage Loan or
Loans, as of the date of substitution, the covenants, representations and
warranties set forth in Section 2.04. The procedures applied by the Seller in
selecting each Eligible Substitute Mortgage Loan shall not be materially adverse
to the interests of the Trustee, the Certificateholders and the Credit Enhancer.

      Section 2.03. Representations and Warranties Regarding the Servicer. The
Servicer represents and warrants to the Trustee and the Credit Enhancer that as
of the Closing Date:

            (i) The Servicer is duly organized and validly existing as a
      national banking association and has the corporate power to own its assets
      and to transact the business in which it is currently engaged. The
      Servicer is duly qualified to do business as a foreign corporation and is
      in good standing in each jurisdiction in which the character of the
      business transacted by it or any properties owned or leased by it requires
      such qualification and in which the failure so to qualify would have a
      material adverse effect on the business, properties, assets, or financial
      condition (or other) of the Servicer;

            (ii) The Servicer has the corporate power and authority to make,
      execute, deliver and perform this Agreement and all of the transactions
      contemplated under the Agreement, and has taken all necessary corporate
      action to authorize the execution, delivery and performance of this
      Agreement. When executed and delivered, this Agreement will constitute the
      legal, valid and binding obligation of the Seller enforceable in
      accordance with its terms, except as enforcement of such terms may be
      limited by bankruptcy, insolvency moratorium, fraudulent conveyance,
      reorganization and similar laws affecting the enforcement of the rights of
      creditors of national banking associations, the deposits of which are
      insured by the FDIC, and subject to general principles of equity, (whether
      applied in a proceeding at law or in equity or of creditors' rights
      generally);

            (iii) The Servicer is not required to obtain the consent of any
      other party or any consent, license, approval or authorization from, or
      registration or declaration with, any governmental authority, bureau or
      agency in connection with the execution, delivery, performance, validity
      or enforceability of this Agreement (other than such consents, licenses,
      approvals or authorizations from, or registrations or declarations with,
      any governmental authority, bureau or agency that, individually or in the
      aggregate, would not have a material adverse effect on the transactions
      contemplated by this Agreement), except for such consent, license,
      approval or authorization, or registration or declaration, as shall have
      been obtained or filed, as the case may be, prior to the Closing Date;


                                       24
<PAGE>   29

            (iv) The execution, delivery and performance of this Agreement by
      the Servicer will not violate any provision of any existing law or
      regulation or any order or decree of any court applicable to the Servicer
      or any provision of the articles of association or bylaws of the Servicer,
      or constitute a material breach of any mortgage, indenture, contract or
      other agreement to which the Service is a party or by which the Servicer
      may be bound (other than violations of such laws, regulations, orders,
      decrees, mortgages, contracts or other agreements that, individually or in
      the aggregate, would not have a material adverse effect on the
      transactions contemplated by this Agreement); and

            (v) No litigation or administrative proceeding of or before any
      court, tribunal or governmental body is currently pending, or to the
      knowledge of the Servicer threatened, against the Servicer or any of its
      properties or with respect to this Agreement or the Investor Certificates
      or the Transferor Interest, which in the opinion of the Servicer has a
      reasonable likelihood of resulting in a material adverse effect on the
      transactions contemplated by this Agreement.

The representations and warranties set forth in this Section shall survive the
sale and assignment of the Mortgage Loans to the Trust. Upon discovery of a
breach of any representations and warranties which materially and adversely
affects the interests of the Certificateholders or the Credit Enhancer, the
person discovering such breach shall give prompt written notice to the other
parties and to the Credit Enhancer. Within 90 days of its discovery or its
receipt of notice of breach, or, with the prior written consent of a Responsible
Officer of the Trustee, such longer period specified in such consent, the
Servicer shall cure such breach in all material respects.

      Section 2.04. Representations and Warranties of the Seller Regarding the
Mortgage Loans; Retransfer of Certain Mortgage Loans. (a) The Seller hereby
represents and warrants to the Trustee and the Credit Enhancer that as of the
Cut-Off Date, unless otherwise specifically set forth herein:

            (i) As of the Closing Date, this Agreement constitutes a legal,
      valid and binding obligation of the Seller, enforceable against the Seller
      in accordance with its terms, except as enforcement of such terms may be
      limited by bankruptcy, insolvency, reorganization, moratorium or other
      similar laws now or hereafter in effect affecting the enforcement of
      creditors' rights generally and by the availability of equitable remedies;

            (ii) As of the Closing Date with respect to the Mortgage Loans and
      as of the applicable Transfer Date with respect to any Eligible Substitute
      Mortgage Loan, either (A) the Purchase Agreement constitutes a valid
      transfer and assignment to the Depositor of all right, title and interest
      of the Seller in and to each Mortgage Loan (including its Cut-Off Date
      Asset Balance), all monies due or to become due with respect thereto, and
      all proceeds of such Cut-Off Date Asset Balances with respect to the
      Mortgage Loans and such funds as are from time to time deposited in the
      Collection Account (excluding any investment earnings thereon) and all
      other property specified in the definition of "Asset" as being part of the
      corpus of the Trust conveyed to the Trust by the Depositor, and (upon
      payment for the Additional Balances), will constitute a valid transfer and
      assignment to the Trustee of all right, title and interest of the Seller
      in and to the Additional Balances, all monies due or to become due with
      respect thereto, and all proceeds of such Additional


                                       25
<PAGE>   30

      Balances and all other property specified in the definition of "Asset"
      relating to the Additional Balances or (B) the Purchase Agreement or this
      Agreement, as appropriate, constitutes a grant of a security interest (as
      defined in the UCC as in effect in Ohio) in such property to the Trustee
      on behalf of the Trust. If this Agreement constitutes the grant of a
      security interest to the Trust in such property, and if the Trustee
      obtains and maintains possession of the Mortgage File for each Mortgage
      Loan, the Trust shall have a first priority perfected security interest in
      such property, subject to the effect of Section 9-306 of the UCC with
      respect to collections on the Mortgage Loans that are deposited in the
      Collection Account in accordance with the next to last paragraph of
      Section 3.02(b); provided, however, that nothing in this clause (ii) shall
      be construed to obligate the Servicer to deliver any Mortgage Files other
      than as set forth in Section 2.01 hereof;

            (iii) As of the Closing Date with respect to the Mortgage Loans and
      the applicable Transfer Date with respect to any Eligible Substitute
      Mortgage Loan and as of the date any Additional Balance is created, the
      information set forth in the Mortgage Loan Schedule for such Mortgage
      Loans is true and correct in all material respects;

            (iv) The applicable Cut-Off Date Asset Balance has not been assigned
      or pledged, and the Seller is the sole owner and holder of such Cut-Off
      Date Asset Balance free and clear of any and all liens, claims,
      encumbrances, participation interests, equities, pledges, charges or
      security interests of any nature, and has full right and authority, under
      all governmental and regulatory bodies having jurisdiction over the
      ownership of the applicable Mortgage Loan, to sell, assign or transfer the
      same pursuant to the Purchase Agreement;

            (v) As of the Closing Date with respect to the Mortgage Loans and
      the applicable Transfer Date with respect to any Eligible Substitute
      Mortgage Loan, the related Mortgage Note and the Mortgage with respect to
      each Mortgage Loan have not been assigned or pledged, and the Seller is
      the sole owner and holder of the Mortgage Loan free and clear of any and
      all liens, claims, encumbrances, participation interests, equities,
      pledges, charges or security interests of any nature, and has full right
      and authority, under all governmental and regulatory bodies having
      jurisdiction over the ownership of the applicable Mortgage Loans, to sell,
      assign or transfer the same pursuant to the Purchase Agreement;

            (vi) As of the Closing Date with respect to the Mortgage Loans and
      the applicable Transfer Date with respect to any Eligible Substitute
      Mortgage Loan, the related Mortgage is a valid and subsisting first,
      second or more junior lien, as set forth on the Mortgage Loan Schedule
      with respect to each related Mortgage Loan, on the property therein
      described, and as of the applicable Cut-off Date the related Mortgaged
      Property is free and clear of all encumbrances and liens having priority
      over the first, second or more junior lien, as applicable, of such
      Mortgage except for liens for (i) real estate taxes and special
      assessments not yet delinquent; (ii) income taxes, (iii) any first or
      similar mortgage loan secured by such Mortgaged Property and specified on
      the Mortgage Loan Schedule; (iv) covenants, conditions and restrictions,
      rights of way, easements and other matters of public record as of the date

With respect to the representations and warranties set forth in Section 2.04(a)
that are made to the best knowledge of the Seller, if it is discovered by the
Seller, the Depositor, the Servicer or a Responsible Officer of the Trustee that
the substance of such representation and warranty is inaccurate and such
inaccuracy materially and adversely affects the value of the related Mortgage
Loan then, notwithstanding the Seller's lack of knowledge with respect to the
substance of such representation and warranty being inaccurate at the time the
representation or warranty was made, such inaccuracy shall be deemed a breach of
the applicable representation or warranty and subject the Seller to the
obligations set forth in Section 2.04(b).

      (b) It is understood and agreed that the representations and warranties
set forth in this Section 2.04 shall survive delivery of the respective Mortgage
Files to the Trustee pursuant to Section 2.01 and the termination of the rights
and obligations of the Servicer pursuant to Section 7.04 or 8.02. Upon discovery
by the Seller, the Depositor, the Servicer, the Credit Enhancer or a Responsible
Officer of the Trustee of a breach of any of the foregoing representations and
warranties which materially and adversely affects the interests of the Trust or
the Investor Certificateholders or the Credit Enhancer in the related Mortgage
Loan, the party discovering such breach shall give prompt written notice to the
other parties and the Credit Enhancer. Within 90 days of its discovery or its
receipt of notice of such breach, the Seller shall use all reasonable efforts to
cure such breach in all material respects or shall, not later than the Business
Day next preceding the Distribution Date in the month following the Collection
Period in which any such


                                       29
<PAGE>   34

cure period expired (or such later date that is acceptable to the Trustee and
the Credit Enhancer as evidenced by their written consents), either (a) accept a
transfer of such Mortgage Loan from the Trust or (b) substitute an Eligible
Substitute Mortgage Loan in the same manner and subject to the same conditions
as set forth in Section 2.02; provided, however, that the cure for any breach of
a representation and warranty relating to the characteristics of the Mortgage
Loans in the aggregate shall be a repurchase of or substitution for only the
Mortgage Loans necessary to cause such characteristics to be in compliance with
the related representation and warranty. Upon accepting such transfer and making
any required deposit into the Collection Account or substitution of an Eligible
Substitute Mortgage Loan, as the case may be, the Seller shall be entitled to
receive an instrument of assignment or transfer from the Trustee to the same
extent as set forth in Section 2.02 with respect to the transfer of Mortgage
Loans under that Section.

      It is understood and agreed that the obligation of the Seller to accept a
transfer of a Mortgage Loan as to which a breach has occurred and is continuing
and to make any required deposit in the Collection Account or to substitute an
Eligible Substitute Mortgage Loan, as the case may be, shall constitute the sole
remedy against the Seller respecting such breach available to Investor
Certificateholders, the Trustee on behalf of Investor Certificateholders and the
Credit Enhancer. Notwithstanding the foregoing, with regard to any breach of the
representation and warranty set forth in Section 2.04(a)(v), the sale and
assignment of the affected Mortgage Loans to the Trust shall be deemed void and
the Seller shall pay to the Trust the sum of the amount of the related Asset
Balances, plus unpaid accrued interest on each such Asset Balance at the
applicable Loan Rate to the date of payment.

      Section 2.05. Covenants of the Depositor. The Depositor hereby covenants
that:

      (a) Security Interests. Except for the transfer hereunder, the Depositor
will not sell, pledge, assign or transfer to any other Person, or grant, create,
incur, assume or suffer to exist any Lien on any Mortgage Loan, whether now
existing or hereafter created, or any interest therein; the Depositor will
notify the Trustee of the existence of any Lien on any Mortgage Loan immediately
upon discovery thereof; and the Depositor will defend the right, title and
interest of the Trust in, to and under the Mortgage Loans, whether now existing
or hereafter created, against all claims of third parties claiming through or
under the Depositor; provided, however, that nothing in this Section 2.05(a)
shall prevent or be deemed to prohibit the Depositor from suffering to exist
upon any of the Mortgage Loans any Liens for municipal or other local taxes and
other governmental charges if such taxes or governmental charges shall not at
the time be due and payable or if the Depositor shall currently be contesting
the validity thereof in good faith by appropriate proceedings and shall have set
aside on its books adequate reserves with respect thereto.

      (b) Negative Pledge. The Depositor hereby agrees not to transfer, assign,
exchange, pledge, finance, hypothecate, grant a security interest in or
otherwise convey the Transferor Interest except in accordance with Sections 6.05
and 7.02.

(c) Additional Indebtedness. So long as the Investor Certificates are
outstanding the Depositor will not incur any debt other than debt that (i) is
non-recourse to the assets of the Depositor other than the Mortgage Loans
specifically pledged as security for such debt, or (ii) is subordinated in right
of payment to the rights of the Investor Certificateholders or (iii) is


                                       30
<PAGE>   35

assigned a rating by each of the Rating Agencies that is the same as the then
current rating of the Investor Certificates.

      (d) Downgrading. The Depositor will not engage in an activity which would
result in a downgrading of the Investor Certificates.

      (e) Amendment to Certificate of Incorporation. The Depositor will not
amend its Certificate of Incorporation without prior written notice to the
Rating Agencies and the Credit Enhancer.

      (f) Principal Place of Business. The Depositor's principal place of
business is in Ohio and it will not change its principal place of business
without prior written notice to the Rating Agencies.

      Section 2.06. Retransfers of Mortgage Loans at Election of Transferor.
Subject to the conditions set forth below, the Transferor may, but shall not be
obligated to, require the retransfer of Mortgage Loans from the Trust to the
Transferor as of the close of business on a Distribution Date (the "Transfer
Date"). On the fifth Business Day (the "Transfer Notice Date") prior to the
Transfer Date designated in such notice, the Transferor shall give the Trustee
and the Servicer a notice of the proposed retransfer that contains a list of the
Mortgage Loans to be retransferred. Such retransfers of Mortgage Loans shall be
permitted upon satisfaction of the following conditions:

            (i) No Rapid Amortization Event has occurred;

            (ii) On the Transfer Notice Date the Transferor Principal Balance
      (after giving effect to the removal from the Trust of the Mortgage Loans
      proposed to be retransferred) is at least equal to the Minimum Transferor
      Interest;

            (iii) The transfer of any Mortgage Loans on any Transfer Date during
      the Managed Amortization Period shall not, in the reasonable belief of the
      Transferor, cause a Rapid Amortization Event to occur or an event which
      with notice or lapse of time or both would constitute a Rapid Amortization
      Event;

            (iv) On or before the Transfer Date, the Transferor shall have
      delivered to the Trustee a revised Mortgage Loan Schedule, reflecting the
      proposed transfer and the Transfer Date, and the Servicer shall have
      marked the Electronic Ledger to show that the Mortgages Loans transferred
      to the Transferor are no longer owned by the Trust;

            (v) The Transferor shall represent and warrant that no selection
      procedures reasonably believed by the Transferor to be adverse to the
      interests of the Investor Certificateholders or the Credit Enhancer were
      utilized in the selection of the Mortgage Loans to be removed from the
      Trust;

            (vi) In connection with the first retransfer of Mortgage Loans
      pursuant to this Section, each Rating Agency shall have received on or
      prior to the related Transfer Notice Date notice from the Transferor of
      such proposed retransfer of Mortgage Loans and, prior to the Transfer
      Date, shall have notified the Trustee in writing that such


                                       31
<PAGE>   36

      retransfer of Mortgage Loans would not result in a reduction or withdrawal
      of its then current rating of the Investor Certificates without regard to
      the Policy;

            (vii) The Transferor shall have delivered to the Trustee and the
      Credit Enhancer an officer's Certificate certifying that the items set
      forth in subparagraphs (i) through (vi), inclusive, have been performed or
      are true and correct, as the case may be. The Trustee may conclusively
      rely on such Officer's Certificate, shall have no duty to make inquiries
      with regard to the matters set forth therein and shall incur no liability
      in so relying.

Upon receiving the requisite information from the Transferor, the Servicer shall
perform in a timely manner those acts required of it, as specified above. Upon
satisfaction of the above conditions, on the Transfer Date the Trustee shall
deliver, or cause to be delivered, to the Transferor the Mortgage File for each
Mortgage Loan being so transferred, and the Trustee shall execute and deliver to
the Transferor such other documents prepared by the Transferor as shall be
reasonably necessary to transfer such Mortgage Loans to the Transferor. Any such
transfer of the Trust's right, title and interest in and to Mortgage Loans shall
be without recourse, representation or warranty by or of the Trustee or the
Trust to the Transferor.

      Section 2.07. Execution and Authentication of Certificates. The Trustee,
on behalf of the Trust, has caused to be executed, authenticated and delivered
to or upon the order of the Depositor, in exchange for the corpus of the Trust,
concurrently with the sale, assignment and conveyance to the Trustee of the
corpus of the Trust, Investor Certificates in authorized denominations and the
Transferor Interest, together evidencing the ownership of the entire Trust.

      Section 2.08. Tax Treatment. It is the intention of the Depositor, the
Transferor and the Investor Certificateholders that the Investor Certificates
will be indebtedness for federal, state and local income and franchise tax
purposes and for purposes of any other tax imposed on or measured by income. The
terms of the Agreement shall be interpreted to further the intent of the parties
hereto. The Transferor, the Depositor, the Trustee and each Investor
Certificateholder (or Certificate Owner) by acceptance of its Investor
Certificate (or, in the case of a Certificate Owner, by virtue of such
Certificate Owner's acquisition of a beneficial interest therein) agrees to
treat the Investor Certificates (or beneficial interest therein), for purposes
of federal, state and local income or franchise taxes and any other tax imposed
on or measured by income, as indebtedness of the Transferor secured by the
assets of the Trust and to report the transactions contemplated by this
Agreement on all applicable tax returns in a manner consistent with such
treatment. Each Investor Certificateholder agrees that it will cause any
Certificate Owner acquiring an interest in an Investor Certificate through it to
comply with this Agreement as to treatment of the Investor Certificates as
indebtedness for federal, state and local income and franchise tax purposes and
for purposes of any other tax imposed on or measured by income. The Trustee will
prepare and file all tax reports required hereunder.

      Section 2.09. Representations and Warranties of the Depositor. The
Depositor represents and warrants to the Trustee on behalf of the
Certificateholders and the Credit Enhancer as follows:

            (i) This Agreement constitutes a legal, valid and binding obligation
      of the Depositor, enforceable against the Depositor in accordance with its
      terms, except as


                                       32
<PAGE>   37

      enforceability may be limited by applicable bankruptcy, insolvency,
      reorganization, moratorium or other similar laws now or hereafter in
      effect affecting the enforcement of creditors' rights in general and
      except as such enforceability may be limited by general principles of
      equity (whether considered in a proceeding at law or in equity);

            (ii) Immediately prior to the sale and assignment by the Depositor
      to the Trustee of each Mortgage Loan, the Depositor was the sole
      beneficial owner of each Mortgage Loan (insofar as such title was conveyed
      to it by the Seller) subject to no prior lien, claim, participation
      interest, mortgage, security interest, pledge, charge or other encumbrance
      or other interest of any nature;

            (iii) As of the Closing Date, the Depositor has transferred all
      right, title and interest in the Mortgage Loans to the Trustee; and

            (iv) The Depositor has not transferred the Mortgage Loans to the
      Trustee with any intent to hinder, delay or defraud any of its creditors.

                          Administration and Servicing
                                of Mortgage Loans

      Section 3.01. The Servicer.

      (a) The Servicer shall service and administer the Mortgage Loans in a
manner consistent with the terms of this Agreement and with general industry
practice and shall have full power and authority, acting alone or through a
subservicer, to do any and all things in connection with such servicing and
administration which it may deem necessary or desirable, it being understood,
however, that the Servicer shall at all times remain responsible to the Trustee,
the Certificateholders, the Transferor and the Credit Enhancer for the
performance of its duties and obligations hereunder in accordance with the terms
hereof. Any amounts received by any subservicer in respect of a Mortgage Loan
shall be deemed to have been received by the Servicer whether or not actually
received by it. Without limiting the generality of the foregoing, the Servicer
shall continue, and is hereby authorized and empowered by the Trustee, to
execute and deliver, on behalf of itself, the Certificateholders and the
Trustee, or any of them, any and all instruments of satisfaction or
cancellation, or of partial or full release or discharge and all other
comparable instruments, with respect to the Mortgage Loans and with respect to
the Mortgaged Properties. The Trustee shall, upon the written request of a
Servicing officer, furnish the Servicer with any powers of attorney and other
documents necessary or appropriate to enable the Servicer to carry out its
servicing and administrative duties hereunder. The Servicer in such capacity may
also consent to the placing of a lien senior to that of any Mortgage on the
related Mortgaged Property, provided that

                  (x) such Mortgage became a first lien mortgage after the
            related Mortgage Loan was conveyed to the Trust and, immediately
            following the placement of such senior lien, such Mortgage is a
            second lien mortgage and the outstanding principal amount of the
            mortgage loan secured by such senior lien is no greater than the
            outstanding principal amount of the senior mortgage loan secured by
            the Mortgaged Property as of the date the related Mortgage Loan was
            originated; or

                  (y) the Mortgage relating to such Mortgage Loan was in a
            second lien position as of the Cut-Off Date and the new senior lien
            secures a mortgage loan that refinances an existing first mortgage
            loan and the outstanding principal amount of the replacement first
            mortgage loan immediately following such refinancing is not greater
            than the outstanding principal amount of such existing first
            mortgage loan at the date of origination of such Mortgage Loan;
            provided further, that such senior mortgage does not secure a note
            that provides for negative amortization.

      The Servicer may also, without prior approval from the Rating Agencies or
the Credit Enhancer, increase the Credit Limits on Mortgage Loans provided that
(i) based upon a new appraisal, the Combined Loan-to-Value Ratios of the
Mortgage Loans after giving effect to such increase are no greater than __%,
(ii) such increases are consistent with the Servicer's


                                       34
<PAGE>   39

underwriting policies and (iii) the aggregate Credit Limits of such Mortgage
Loans does not exceed __% of the aggregate of the Credit Limits as of the
Cut-Off Date.

      Furthermore, the Servicer may, without prior approval from the Rating
Agencies and the Credit Enhancer solicit or receive requests from Mortgagors for
a reduction in Loan Rates; provided that the aggregate of such reductions shall
not cause the difference between the Cut-Off Date Weighted Average Gross Margin
and the Recalculated Weighted Average Gross Margin to exceed ____%.

      Upon the prior written consent of each of the Rating Agencies, all of the
percentages in the immediately preceding two paragraphs may be modified.

      In addition, the Servicer may agree to changes in the terms of a Mortgage
Loan at the request of the Mortgagor provided that such changes (i) do not
materially and adversely affect the interests of Certificateholders or the
Credit Enhancer and (ii) are consistent with prudent and customary business
practice as evidenced by a certificate signed by a Servicing Officer delivered
to the Trustee and the Credit Enhancer.

      In addition to the foregoing, the Servicer may solicit Mortgagors to
change any other terms of the related Mortgage Loans, provided that such changes
(i) do not materially and adversely affect the interest of Certificateholders or
the Credit Enhancer and (ii) are consistent with prudent and customary business
practice as evidenced by a certificate signed by a Servicing officer delivered
to the Trustee and the Credit Enhancer. Nothing herein shall limit the right of
the Servicer to solicit Mortgagors with respect to new loans (including mortgage
loans) that are not Mortgage Loans.

      The relationship of the Servicer (and of any successor to the Servicer as
servicer under this Agreement) to the Trustee under this Agreement is intended
by the parties to be that of an independent contractor and not that of a joint
venturer, partner or agent.

      (b) In the event that the rights, duties and obligations of the Servicer
are terminated hereunder, any successor to the Servicer in its sole discretion
may, to the extent permitted by applicable law, terminate the existing
subservicer arrangements with any subservicer or assume the terminated
Servicer's rights under such subservicing arrangements which termination or
assumption will not violate the terms of such arrangements.

      Section 3.02. Collection of Certain Mortgage Loan Payments.

      (a) The Servicer shall make reasonable efforts to collect all payments
called for under the terms and provisions of the Mortgage Loans, and shall, to
the extent such procedures shall be consistent with this Agreement, follow such
collection procedures as it follows with respect to mortgage loans in its
servicing portfolio comparable to the Mortgage Loans. Consistent with the
foregoing, and without limiting the generality of the foregoing, the Servicer
may in its discretion (i) waive any late payment charge or any assumption fees
or other fees which may be collected in the ordinary course of servicing such
Mortgage Loan and (ii) arrange with a Mortgagor a schedule for the payment of
interest due and unpaid; provided that such arrangement is


                                       35
<PAGE>   40

consistent with the Servicer's policies with respect to the mortgage loans it
owns and services; provided, further, that notwithstanding such arrangement such
Mortgage Loans will be included in the information regarding delinquent Mortgage
Loans set forth in the Servicing Certificate and monthly statement to
Certificateholders pursuant to Section 5.03.

      (b) The Servicer shall establish and maintain a trust account (the
"Collection Account") titled "___________, as Trustee, in trust for the
registered holders of Banc One ABS Corporation Revolving Home Equity Loan
Asset-Backed Certificates, Series 199_-_ and [Credit Enhancer]." The Collection
Account shall be an Eligible Account. The Servicer shall on the Closing Date
deposit any amounts representing payments on, and any collections in respect of,
the Mortgage Loans received after the Cut-off Date and prior to the Closing
Date, and thereafter the Servicer, or the Seller, as the case may be, shall
deposit within two Business Days following receipt thereof the following
payments and collections received or made by it (without duplication):

            (i) all collections on and in respect of the Mortgage Loans;

            (ii) Net Liquidation Proceeds net of any related Foreclosure Profit;

            (iii) Insurance Proceeds (including, for this purpose any amount
      required to be credited by the Servicer pursuant to the last sentence of
      Section 3.04 and excluding the portion thereof, if any, that has been
      applied to the restoration or repair of the related Mortgaged Property or
      released to the related Mortgagor in accordance with the normal servicing
      procedures of the Servicer); and

            (iv) any amounts required to be deposited therein pursuant to
      Section 10.01;

provided, however, that with respect to each Collection Period, the Servicer
shall be permitted to retain from payments in respect of interest on the
Mortgage Loans, the Servicing Fee for such Collection Period. The foregoing
requirements respecting deposits to the Collection Account are exclusive, it
being understood that, without limiting the generality of the foregoing, the
Servicer need not deposit in the Collection Account amounts representing
Foreclosure Profits, fees or late charge penalties payable by Mortgagors, or
amounts received by the Servicer for the accounts of Mortgagors for application
towards the payment of taxes, insurance premiums, assessments, excess pay off
amounts and similar items. The Servicer shall remit all Foreclosure Profits to
the Seller.

      Notwithstanding the forgoing, so long as the Servicer's short-term
obligations are rated at least "___" and "___" by __________ and ________
respectively, all amounts collected by the Servicer may be commingled with other
general collections of the Servicer and amounts collected on the Mortgage Loans
for each Collection Period shall be deposited in same-day funds into the
Collection Account no later than one Business Day prior to the related
Distribution Date.

      The Trustee shall hold amounts deposited in the Collection Account as
trustee for the Certificateholders and for the Credit Enhancer. In addition, the
Servicer shall notify the Trustee an the Credit Enhancer in writing on each
Determination Date of the amount of payments and collections in the Collection
Account allocable to Interest Collections and Principal Collections


                                       36
<PAGE>   41

for the related Distribution Date. Following such notification, the Servicer
shall be entitled to withdraw from the Collection Account and retain any amounts
that constitute income and gain realized from the investment of such payments
and collections.

      All income and gain realized from any investment in Eligible Investments
of funds in the Collection Account shall be for the benefit of the
Certificateholders. The amount of any losses incurred in respect of the
principal amount of any such investments shall be deemed not to be on deposit in
the Collection Account.

      Section 3.03. Withdrawals from the Collection Account. From time to time,
withdrawals may be made from the Collection Account by the Servicer for the
following purposes:

            (i) To the Servicer as payment for its Servicing Fee pursuant to
      Section 3.08;

            (ii) To pay to the Servicer amounts on deposit in the Account that
      are not to be included in the distributions and payments pursuant to
      Section 5.01 to the extent provided by the second to the last and the last
      paragraph of Section 3.02(b);

            (iii) To make or to permit the Paying Agent to make distributions
      and payments pursuant to Section 5.01; and

            (iv) Prior to the Collection Period preceding the Rapid Amortization
      Commencement Date, to pay to the Seller, the amount of any Additional
      Balances as and when created during the related Collection Period,
      provided, that the aggregate amount so paid to the Seller in respect of
      Additional Balances at any time during any Collection Period shall not
      exceed the amount of Principal Collections theretofore received for such
      Collection Period.

      If the Servicer deposits in the Collection Account any amount not required
to be deposited therein or any amount in respect of payments by Mortgagors made
by checks subsequently returned for insufficient funds or other reason for
non-payment it may at any time withdraw such amount from the Collection Account,
and any such amounts shall not be included in the amounts to be deposited in the
Collection Account pursuant to Section 3.02(b), any provision herein to the
contrary notwithstanding.

      Section 3.04. Maintenance of Hazard Insurance; Property Protection
Expenses. The Servicer shall cause to be maintained for each Mortgage Loan
hazard insurance naming the Servicer or the related subservicer as loss payee
thereunder providing extended coverage in an amount which is at least equal to
the lesser of (i) the replacement value of the improvements securing such
Mortgage Loan from time to time or (ii) the combined principal balance owing on
such Mortgage Loan and any mortgage loan senior to such Mortgage Loan from time
to time. The Servicer shall also maintain on property acquired upon foreclosure,
or by deed in lieu of foreclosure, hazard insurance with extended coverage in an
amount which is at least equal to the lesser of (i) the replacement value from
time to time of the improvements which are a part of such property or (ii) the
combined principal balance owing on such Mortgage Loan and any mortgage loan
senior to such Mortgage Loan at the time of such foreclosure or deed in lieu of


                                       37
<PAGE>   42

foreclosure plus accrued interest and the good-faith estimate of the Servicer of
related Liquidation Expenses to be incurred in connection therewith. Amounts
collected by the Servicer under any such policies shall be deposited in the
Collection Account to the extent called for by Section 3.02. In cases in which
any Mortgaged Property is located in a federally designated flood area, the
hazard insurance to be maintained for the related Mortgage Loan shall include
flood insurance. All such flood insurance shall be in such amounts as are
required under applicable guidelines of the Federal Flood Emergency Act. The
Servicer shall be under no obligation to require that any Mortgagor maintain
earthquake or other additional insurance and shall be under no obligation itself
to maintain any such additional insurance on property acquired in respect of a
Mortgage Loan, other than pursuant to such applicable laws and regulations as
shall at any time be in force and as shall require such additional insurance. If
the Servicer shall obtain and maintain a blanket insurance policy consistent
with prudent industry standards insuring against hazard losses on all of the
Mortgage Loans in an aggregate amount prudent under industry standards, it shall
conclusively be deemed to have satisfied its obligations as set forth in the
first sentence of this Section 3.04. Such blanket insurance policy may provide
for a deductible. In the event a loss on a Mortgage Property occurs which would
have been covered by the hazard insurance policy required by the first sentence
of this Section 3.04, the Servicer shall deposit into the Collection Account,
the amount not payable under the blanket policy because of such deductible.

      Section 3.05. Assumption and Modification Agreements. In any case in which
a Mortgaged Property has been or is about to be conveyed by the Mortgagor, the
Servicer shall exercise its right to accelerate the maturity of such Mortgage
Loan consistent with the then current practice of the Servicer and without
regard to the inclusion of such Mortgage Loan in the Trust. If it elects not to
enforce its right to accelerate or if it is prevented from doing so by
applicable law, the Servicer (so long as such action conforms with the
underwriting standards generally acceptable in the industry at the time for new
origination) is authorized to take or enter into an assumption and modification
agreement from or with the Person to whom such Mortgaged Property has been or is
about to be conveyed, pursuant to which such Person becomes liable under the
Credit Line Agreement and, to the extent permitted by applicable law, the
Mortgagor remains liable thereon. The Servicer shall notify the Trustee that any
assumption and modification agreement has been completed by delivering to the
Trustee an Officer's Certificate certifying that such agreement is in compliance
with this Section 3.05 and by forwarding to the applicable Custodian, as agent
for the Trustee, the original copy of such assumption and modification
agreement. Any such assumption and modification agreement shall, for all
purposes, be considered a part of the related Mortgage File to the same extent
as all other documents and instruments constituting a part thereof. No change in
the terms of the related Credit Line Agreement may be made by the Servicer in
connection with any such assumption to the extent that such change would not be
permitted to be made in respect of the original Credit Line Agreement pursuant
to the fourth paragraph of Section 3.01(a). Any fee collected by the Servicer
for entering into any such agreement will be retained by the Servicer as
additional servicing compensation.

      Section 3.06. Realization Upon Defaulted Mortgage Loans. The Servicer
shall foreclose upon or otherwise comparably convert to ownership Mortgaged
Properties securing such of the Mortgage Loans as come into and continue in
default when, in the opinion of the Servicer based upon the practices and
procedures referred to in the following sentence, no satisfactory


                                       38
<PAGE>   43

arrangements can be made for collection of delinquent payments pursuant to
Section 3.02; provided that if the Servicer has actual knowledge or reasonably
believes that any Mortgaged Property is affected by hazardous or toxic wastes or
substances and that the acquisition of such Mortgaged Property would not be
commercially reasonable, then the Servicer will not cause the Trust to acquire
title to such Mortgaged Property in a foreclosure or similar proceeding. In
connection with such foreclosure or other conversion, the Servicer shall follow
such practices (including, in the case of any default on a related senior
mortgage loan, the advancing of funds to correct such default) and procedures as
it shall deem necessary or advisable and as shall be normal and usual in its
general mortgage servicing activities. The foregoing is subject to the proviso
that the Servicer shall not be required to expend its own funds in connection
with any foreclosure or towards the correction of any default on a related
senior mortgage loan or restoration of any property unless it shall determine
that such expenditure will increase Net Liquidation Proceeds.

      If title to any Mortgaged Property is acquired in foreclosure or by deed
in lieu of foreclosure, the deed or certificate of sale shall be issued to the
Trustee, or to its nominee on behalf of Certificateholders.

      Section 3.07. Trustee to Cooperate. On or before each Distribution Date,
the Servicer will notify the Trustee of the payment in full of the Asset Balance
of any Mortgage Loan during the preceding Collection Period, which notification
shall be by a certification (which certification shall include a statement to
the effect that all amounts received in connection with such payment which are
required to be deposited in the Collection Account pursuant to Section 3.02 have
been so deposited or credited) of a Servicing Officer. Upon any such payment in
full, the Servicer is authorized to execute, pursuant to the authorization
contained in Section 3.01, if the assignments of Mortgage have been recorded as
required hereunder, an instrument of satisfaction regarding the related
Mortgage, which instrument of satisfaction shall be recorded by the Servicer if
required by applicable law and be delivered to the Person entitled thereto. It
is understood and agreed that no expenses incurred in connection with such
instrument of satisfaction or transfer shall be reimbursed from amounts
deposited in the Collection Account. If the Trustee is holding the Mortgage
Files, from time to time and as appropriate for the servicing or foreclosure of
any Mortgage Loan, or in connection with the payment in full of the Asset
Balance of any Mortgage Loan, the Trustee shall, upon request of the Servicer
and delivery to the Trustee of a Request for Release substantially in the form
attached hereto as Exhibit [_] signed by a Servicing officer, release the
related Mortgage File to the Servicer and the Trustee shall execute such
documents, in the forms provided by the Servicer, as shall be necessary to the
prosecution of any such proceedings or the taking of other servicing actions.
Such trust receipt shall obligate the Servicer to return the Mortgage File to
the Trustee when the need therefor by the Servicer no longer unless the Mortgage
Loan shall be liquidated, in which case, upon receipt of a certificate of a
Servicing Officer similar to that hereinabove specified, the trust receipt shall
be released by the Trustee or such Custodian to the Servicer.

      In order to facilitate the foreclosure of the Mortgage securing any
Mortgage Loan that is in default following recordation of the assignments of
Mortgage in accordance with the provisions hereof, the Trustee shall, if so
requested in writing by the Servicer, execute an appropriate assignment in the
form provided to the Trustee by the Servicer to assign such Mortgage Loan for
the purpose of collection to the Servicer or to the related subservicer (any


                                       39
<PAGE>   44

such assignment shall unambiguously indicate that the assignment is for the
purpose of collection only), and, upon such assignment, the Servicer will
thereupon bring all required actions in its own name and otherwise enforce the
terms of the Mortgage Loan and deposit the Net Liquidation Proceeds, exclusive
of Foreclosure Profits, received with respect thereto in the Collection Account.
In the event that all delinquent payments due under any such Mortgage Loan are
paid by the Mortgagor and any other defaults are cured, then the Servicer shall
promptly reassign such Mortgage Loan to the Trustee and return the related
Mortgage File to the place where it was being maintained.

      Section 3.08. Servicing Compensation; Payment of Certain Expenses by
Servicer. The Servicer shall be entitled to receive the Servicing Fee pursuant
to Section 3.03 as compensation for its services in connection with servicing
the Mortgage Loans. Moreover, additional servicing compensation in the form of
late payment charges or other receipts not required to be deposited in the
Collection Account (other than Foreclosure Profits) shall be retained by the
Servicer. The Servicer shall be required to pay all expenses incurred by it in
connection with its activities hereunder (including payment of all other fees
and expenses not expressly stated hereunder to be for the account of the
Certificateholders) and shall not be entitled to reimbursement therefor except
as specifically provided herein. Liquidation Expenses are reimbursable to the
Servicer solely from related Liquidation Proceeds.

      Section 3.09. Annual Statement as to Compliance.

      (a) The Servicer will deliver to the Trustee, the Credit Enhancer and the
Rating Agencies, on or before _____ ____of each year, beginning_________, 199_,
an Officer's Certificate stating that (i) a review of the activities of the
Servicer during the preceding fiscal year (or such shorter period as is
applicable in the case of the first report) and of its performance under this
Agreement has been made under such officer's supervision and (ii) to the best of
such officer's knowledge, based on such review, the Servicer has fulfilled all
of its material obligations under this Agreement throughout such fiscal year,
or, if there has been a default in the fulfillment of any such obligation,
specifying each such default known to such officer and the nature and status
thereof.

      (b) The Servicer shall deliver to the Trustee, the Credit Enhancer and
each of the Rating Agencies, promptly after having obtained knowledge thereof,
but in no event later than five Business Days thereafter, written notice by
means of an Officer's Certificate of any event which with the giving of notice
or the lapse of time or both, would become an Event of Servicing Termination.

      Section 3.10. Annual Servicing Report. On or before ______ of each year,
beginning ______ __, 199_, the Servicer, at its expense, shall cause a firm of
nationally recognized independent public accountants (who may also render other
services to the Servicer) to furnish a report to the Trustee, the Credit
Enhancer and each Rating Agency to the effect that such firm has examined
certain documents and records relating to the servicing of mortgage loans during
the most recent fiscal year then ended under pooling and servicing agreements
(substantially similar to this Agreement, including this Agreement) that such
examination, was conducted substantially in compliance with the Uniform Single
Audit Program for Mortgage Bankers and that such examination has disclosed no
items of noncompliance with the provisions of this

required by applicable regulations of the office of Thrift Supervision and the
FDIC (acting as operator of the SAIF or the BIF), such access being afforded
without charge but only upon reasonable request and during normal business hours

the obligation of the Servicer to observe any applicable law prohibiting
disclosure of information regarding the Mortgagors and the failure of the
Servicer to provide access as provided in this Section 3.12 as a result of such
obligation shall not constitute a breach of this Section 3.12.

      (b) The Servicer shall supply information in such form as the Trustee
shall reasonably request to the Trustee and the Paying Agent, on or before the
start of the Determination Date preceding the related Distribution Date, as is

Trustee, as the case may be, to make required distributions and to furnish the
required reports to Certificateholders and to make any claim under the Policy.

      Section 3.13. Maintenance of Certain Servicing Insurance Policies. The
Servicer shall during the term of its service as servicer maintain in force (i)

performance of its obligations as master servicer hereunder and (ii) a fidelity

policies and bond together shall comply with the requirements from time to time
of the Federal National Mortgage Association for persons performing servicing

      Section 3.14. Reports to the Securities and Exchange Commission. The
Trustee shall, on behalf of the Trust, cause to be filed with the Securities and
Exchange Commission any periodic reports required to be filed under the
provisions of the Securities Exchange Act of 1934, as amended, and the rules and

costs, expenses or liabilities of the Servicer, the Trustee or the Trust Fund.
Amounts paid under the Policy shall be transferred to the Collection Account in
accordance with the next succeeding paragraph and disbursed by the Trustee to
Holders of Investor Certificates in accordance with Section 5.01. It shall not
be necessary for such payments to be made by checks or wire transfers separate
from the checks or wire transfers used to pay the Guaranteed Distribution with
other funds available to make such payment. However, the amount of any payment
of principal of or interest on the Investor Certificates to be paid from funds
transferred from the Policy Payments Account shall be noted as provided in
paragraph (c) below in the Certificate Register and in the statement to be
furnished to Holders of the Investor Certificates pursuant to Section 5.03.

      On any Distribution Date with respect to which a claim has been made under
the Policy, the amount of any funds received by the Trustee as a result of any
claim under the Policy, to the extent required to make the Guaranteed
Distribution on such Distribution Date, shall be withdrawn from the Policy
Payments Account and deposited in the Collection Account and applied by the
Trustee, together with the other funds to be withdrawn from the Collection
Account pursuant to Section 5.01 directly to the payment in full of the
Guaranteed Distribution due on the Investor Certificates. Any funds received by
the Trustee shall be used solely for payment to the Holders of Investor
Certificates and may not be applied to satisfy any costs, expenses or
liabilities of the Servicer, the Trustee or the Trust. Any funds remaining in
the Policy Payments Account on the first Business Day following a Distribution
Date shall be remitted to the Credit Enhancer, pursuant to the instructions of
the Credit Enhancer, by the end of such Business Day.

      (c) The Trustee shall keep a complete and accurate record of the amount of
interest and principal paid in respect of any Investor Certificate from moneys
received under the Policy. The Credit Enhancer shall have the right to inspect
such records at reasonable times during normal business hours upon one Business
Day's prior notice to the Trustee.

      (d) The Trustee shall promptly notify the Credit Enhancer and Fiscal Agent
of any proceeding or the institution of any action, of which a Responsible
Officer of the Trustee has actual knowledge, seeking the avoidance as a
preferential transfer under applicable bankruptcy, insolvency, receivership or
similar law (a "Preference Claim") of any distribution made with respect to the
Investor Certificates. Each Investor Certificateholder, by its purchase of
Investor Certificates, the Servicer and the Trustee hereby agree that, the
Credit Enhancer (so long as no Credit Enhancer Default exists) may at any time
during the continuation of any proceeding relating to a Preference Claim direct
all matters relating to such Preference Claim, including, without limitation,
(i) the direction of any appeal of any order relating to such Preference Claim
and (ii) the posting of any surety, supersede as or performance bond pending any
such appeal. In addition and without limitation of the foregoing, the Credit
Enhancer shall be subrogated to the rights of the Servicer, the Trustee and each
Investor Certificateholder in the conduct of any such Preference Claim,
including, without limitation, all rights of any party to an adversary
proceeding action with respect to any court order issued in connection with any
such Preference Claim. 

      Section 4.03. Spread Account.

      (a) The Trustee shall establish and maintain a separate trust account (the
"Spread Account") titled "_______________, as Trustee, in trust for the
registered holders of Banc One ABS Corporation Revolving Home Equity Loan Asset
Backed Certificates, Series 199_-_ and [Credit Enhancer]." The Spread Account
shall be an Eligible Account. Amounts on deposit in the Spread Account will, at
the direction of the Transferor, be invested in either Eligible Investments
maturing no later than the day before the next Distribution Date or in the
commercial paper (maturing no later than the day before the next Distribution
Date) of Bank One, N.A. or any of its Affiliates, provided that such commercial
paper's or other short-term obligation's short-term rating is no lower than
"___" and "___"by ______ and _______, respectively, and the long-term unsecured
debt of Bank One, N.A. is rated at least "___" and


                                       46
<PAGE>   51

"___" by ______ and ________, respectively, or such lower rating as is agreed to
by the Rating Agencies as evidenced by a letter from each such Rating Agency.

      All income and gain realized from any investment of funds in the Spread
Account shall be for the benefit of the Transferor and shall be subject to its
withdrawal from time to time. The amount of any losses incurred in respect of
the principal amount of any such investments shall be deemed not to be on
deposit in the Spread Account.

      (b) On each Determination Date the Trustee shall determine (i) the extent
to which Investor Interest Collections applied in the order specified in Section
5.01(a) are insufficient to make distributions as provided in clauses (iii) and
(iv) of Section 5.01(a) and (ii) the Guaranteed Principal Distribution Amount
for the related Distribution Date. On each Distribution Date the Trustee shall
withdraw from the Spread Account and deposit into the Collection Account the
lesser of the amount on deposit in the Spread Account and an amount equal to the
sum of the amounts, if any, determined in clauses (i) and (ii) of the preceding
sentence.

      (c) Following the termination of the Trust pursuant to Section 10.01 or
11.02 hereof, the Trustee shall withdraw all amounts then on deposit in the
Spread Account and distribute such amounts first to any amounts due and owing to
the Credit Enhancer and then to the Transferor. If on any Distribution Date the
amount on deposit in the Spread Account exceeds the Spread Account Requirement,
the Trustee shall withdraw such excess and distribute it to the Transferor.

      Section 4.04. Effect of Payments by the Credit Enhancer; Subrogation.
Anything herein to the contrary notwithstanding, any payment with respect to
principal of or interest on any of the Investor Certificates which is made with
monies received pursuant to the terms of the Policy shall not be considered
payment of such Investor Certificates from the Trust and shall not result in the
payment of or the provision for the payment of the principal of or interest on
such Investor Certificates within the meaning of Section 5.01. The Depositor,
the Servicer and the Trustee acknowledge, and each Holder by its acceptance of
an Investor Certificate agrees, that without the need for any further action on
the part of the Credit Enhancer, the Depositor, the Servicer, the Trustee or the
Certificate Registrar (a) to the extent the Credit Enhancer makes payments,
directly or indirectly, on account of principal of or interest on any Investor
Certificates to the Holders of such Certificates, the Credit Enhancer will be
fully subrogated to the rights of such Holders to receive such principal and
interest from the Trust and (b) the Credit Enhancer shall be paid such principal
and interest but only from the sources and in the manner provided herein for the
Payment of such principal and interest.

      The Trustee and the Servicer shall cooperate in all respects with any
reasonable request by the Credit Enhancer for action to preserve or enforce the
Credit Enhancer's rights or interests under this Agreement without limiting the
rights or affecting the interests of the Holders as otherwise set forth herein.

                                The Certificates

      Section 6.01. The Certificates. The Investor Certificates shall be
substantially in the forms set forth in Exhibit A and shall, on original issue,
be executed, authenticated and delivered by the Trustee to or upon the order of
the Depositor concurrently with the sale and assignment to the Trustee of the
Trust. The Investor Certificates shall be initially evidenced by one or more
certificates representing the entire original Investor Certificate Principal
Balance and shall be held in minimum dollar denominations of $1,000 and integral
dollar multiples in excess thereof, except that one Investor Certificate may be
in a different denomination of less than $1,000 so that the sum of the
denominations of all outstanding Investor Certificates shall equal the Original
Investor Certificate Principal Balance. The sum of the denominations of all
outstanding Investor Certificates shall equal the Original Investor Certificate
Principal Balance. The Transferor Interest initially shall be an uncertificated
interest issued upon the order of the Depositor to the Trustee concurrently with
the sale and assignment to the Trustee of the Trust. The Transferor Interest may
be certificated pursuant to Section 6.02(a). The Transferor Interest shall
represent the entire interest in the assets of the Trust other than that
represented by the Investor Certificates and shall initially be issued to the
Seller.

      The Certificates shall be executed by manual or facsimile signature on
behalf of the Trustee by an authorized officer under its seal imprinted thereon.
Certificates bearing the manual or facsimile signatures of individuals who were,
at the time when such signatures were affixed, authorized to sign on behalf of
the Trustee shall bind the Trust, notwithstanding that such individuals or any
of them have ceased to be so authorized prior to the authentication and delivery
of such Certificates or did not hold such offices at the date of such
Certificates. No Certificate shall be entitled to any benefit under this
Agreement, or be valid for any purpose, unless such Certificate shall have been
manually authenticated by the Trustee substantially in the form provided for
herein, and such authentication upon any Certificate shall be conclusive
evidence, and the only evidence, that such Certificate has been duly
authenticated and delivered hereunder. All Certificates shall be dated the date
of their authentication. Subject to Section 6.02(c), the Investor Certificates
shall be Book-Entry Certificates. The Transferor Interest shall not be
Book-Entry Certificates.

      Section 6.02. Registration of Transfer and Exchange of Investor
Certificates; Appointment of Registrar.

      (a) The Certificate Registrar shall cause to be kept at the Corporate
Trust Office a Certificate Register in which, subject to such reasonable
regulations as it may prescribe, the Certificate Registrar shall provide for the
registration of Investor Certificates and the Transferor Interest and of
transfers and exchanges of Investor Certificates and the Transferor Interest as
herein provided. The Trustee shall initially serve as Certificate Registrar for
the purpose of registering Investor Certificates and the Transferor Interest and
transfers and exchanges of Investor Certificates and the Transferor Interest as
herein provided.

      Upon surrender for registration of transfer of any Investor Certificate at
any office or agency of the Certificate Registrar maintained for such purpose
pursuant to the foregoing


                                       52
<PAGE>   57

paragraph, the Trustee on behalf of the Trust shall execute, authenticate and
deliver, in the name of the designated transferee or transferees, one or more
new Investor Certificates of the same aggregate Percentage Interest. Upon
direction by the Transferor to the Trustee and the Certificate Registrar, the
Trustee shall issue the Transferor Interest in a certificated form substantially
in a form as set forth in Exhibit B. Upon notification by the Transferor to the
Certificate Registrar of a transfer of the Transferor Interest and subject to
Section 6.05, the Trustee on behalf of the Trust shall note on the Certificate
Register the transfer of the Transferor Interest.

      At the option of the Investor Certificateholders, Investor Certificates
may be exchanged for other Investor Certificates in authorized denominations and
the same aggregate Percentage Interests, upon surrender of the Investor
Certificates to be exchanged at any such office or agency. Whenever any Investor
Certificates are so surrendered for exchange, the Trustee shall execute and
authenticate and deliver the Investor Certificates which the Investor
Certificateholder making the exchange is entitled to receive. Every Investor
Certificate presented or surrendered for transfer or exchange shall (if so
required by the Trustee or the Certificate Registrar) be duly endorsed by, or be
accompanied by a written instrument of transfer in form satisfactory to the
Trustee and the Certificate Registrar duly executed by, the Holder thereof or
his attorney duly authorized in writing.

      (b) Except as provided in paragraph (c) below, the Book-Entry Certificates
shall at all times remain registered in the name of the Depository or its
nominee and at all times: (i) registration of the Investor Certificates may not
be transferred by the Trustee except to another Depository; (ii) the Depository
shall maintain book-entry records with respect to the Certificate Owners and
with respect to ownership and transfers of such Investor Certificates; (iii)
ownership and transfers of registration of the Investor Certificates on the
books of the Depository shall be governed by applicable rules established by the
Depository; (iv) the Depository may collect its usual and customary fees,
charges and expenses from its Depository Participants; (v) the Trustee shall
deal with the Depository as representative of the Certificate Owners of the
Investor Certificates for purposes of exercising the rights of Holders under
this Agreement, and requests and directions for and votes of such representative
shall not be deemed to be inconsistent if they are made with respect to
different Certificate Owners; and (vi) the Trustee may rely and shall be fully
protected in relying upon information furnished by the Depository with respect
to its Depository Participants and furnished by the Depository Participants with
respect to indirect participating firms and Persons shown on the books of such
indirect participating firms as direct or indirect Certificate Owners.

      All transfers by Certificate Owners of Book-Entry Certificates shall be
made in accordance with the procedures established by the Depository Participant
or brokerage firm representing such Certificate Owners. Each Depository
Participant shall only transfer Book-Entry Certificates of Certificate Owners
that it represents or of brokerage firms for which it acts as agent in
accordance with the Depository's normal procedures. The parties hereto are
hereby authorized to execute a Letter of Representations with the Depository or
take such other action as may be necessary or desirable to register a Book-Entry
Certificate to the Depository. In the event of any conflict between the terms of
any such Letter of Representation and this Agreement the terms of this Agreement
shall control.

      (c) If (i)(x) the Depository or the Depositor advises the Trustee in
writing that the Depository is no longer willing or able to discharge properly
its responsibilities as Depository, and (y) the Trustee or the Depositor is
unable to locate a qualified successor, (ii) the Depositor, at its sole option,
with the consent of the Trustee, elects to terminate the book-entry system
through the Depository or (iii) after the occurrence of an Event of Servicing
Termination, the Depository, at the direction of Certificate Owners representing
Percentage Interests aggregating not less than 51%. advises the Trustee in
writing that the continuation of a book-entry system through the Depository to
the exclusion of definitive, fully registered Investor Certificates (the
"Definitive Certificates") to Certificate Owners is no longer in the best
interests of the Certificate Owners. Upon surrender to the Certificate Registrar
of the Investor Certificates by the Depository, accompanied by registration
instructions from the Depository for registration, the Trustee shall execute and
authenticate the Definitive Certificates. Neither the Depositor nor the Trustee
shall be liable for any delay in delivery of such instructions and may
conclusively rely on, and shall be protected in relying on, such instructions.
Upon the issuance of Definitive Certificates, all references herein to
obligations imposed upon or to be performed by the Depository shall be deemed to
be imposed upon and performed by the Trustee, to the extent applicable with
respect to such Definitive, Certificates and the Trustee, the Certificate
Registrar, the Servicer and the Depositor shall recognize the Holders of the
Definitive Certificates as Certificateholders hereunder.

      No service charge shall be made for any registration of transfer or
exchange of Investor Certificates, but the Certificate Registrar may require
payment of a sum sufficient to cover any tax or governmental charge that may be
imposed in connection with any transfer or exchange of Certificates.

      All Investor Certificates surrendered for registration of transfer or
exchange shall be cancelled by the Certificate Registrar and disposed of
pursuant to its standard procedures.

      Section 6.03. Mutilated, Destroyed, Lost or Stolen Certificates. If (i)
any mutilated Certificate is surrendered to the Certificate Registrar or the
Certificate Registrar receives evidence to its satisfaction of the destruction,
loss or theft of any Certificate, and (ii) there is delivered to the Trustee,
the Depositor and the Certificate Registrar such security or indemnity as may be
required by them to save each of them harmless, then, in the absence of notice
to the Trustee or the Certificate Registrar that such Certificate has been
acquired by a bona fide purchaser, the Trustee shall execute, authenticate and
deliver in exchange for or in lieu of any such mutilated, destroyed, last or
stolen Certificate, a new Certificate of like tenor and Percentage Interest.
Upon the issuance of any new Certificate under this Section 6.03, the Trustee or
the Certificate Registrar may require the payment of a sum sufficient to cover
any tax or other governmental charge that may be imposed in relation thereto and
any other expenses (including the fees and expenses of the Trustee and the
Certificate Registrar) connected therewith. Any duplicate Certificate issued
pursuant to this Section 6.03, shall constitute complete and indefeasible
evidence of ownership in the Trust, as if originally issued, whether or not the
lost, stolen or destroyed Certificate shall be found at any time.

      Section 6.04. Persons Deemed Owners. Prior to due presentation of a
Certificate or the Transferor Interest for registration of transfer, the
Servicer, the Depositor, the Trustee, the Certificate Registrar, any Paying
Agent and any agent of the Servicer, the Depositor, the Trustee,


                                       54
<PAGE>   59

any Paying Agent or the Certificate Registrar may treat the Person, including a
Depository, in whose name any Certificate or the Transferor Interest is
registered as the owner of such Certificate or Transferor Interest for the
purpose of receiving distributions pursuant to Section 5.01 and for all other
purposes whatsoever, and none of the Servicer, the Depositor, the Trustee the
Certificate Registrar, any Paying Agent or any agent of any of them shall be
affected by notice to the contrary.

      Section 6.05. Restrictions on Transfer of Transferor Interest.

      (a) The Transferor Interest shall be assigned, transferred, exchanged,
pledged, financed, hypothecated or otherwise conveyed (collectively, for
purposes of this Section 6.05 and any other Section referring to the Transferor
Interest, "transferred" or a "transfer") only in accordance with this Section
6.05.

      (b) No transfer of a Transferor Interest shall be made unless such
transfer is exempt from the registration requirements of the Securities Act of
1933, as amended, and any applicable state securities laws or is made in
accordance with said Act and laws. Except for the initial issuance of the
Transferor Interest to the Transferor, the Trustee shall require (i) the
transferee to execute an investment letter acceptable to and in form and
substance satisfactory to the Trustee certifying to the Trustee the facts
surrounding such transfer, which investment letter shall not be an expense of
the Trustee or (ii) if the investment letter is not delivered, a written Opinion
of Counsel acceptable to and in form and substance satisfactory to the Trustee
and the Depositor that such transfer may be made pursuant to an exemption,
describing the applicable exemption and the basis therefor, from said Act or is
being made pursuant to said Act, which Opinion of Counsel shall not be an
expense of the Trustee or the Depositor. The Holder of a Transferor Interest
desiring to effect such transfer shall, and does hereby agree to, indemnify the
Transferor against any liability that may result if the transfer is not so
exempt or is not made in accordance with such federal and state laws.

      (c) The Transferor Interest and any interest therein shall not be
transferred except upon satisfaction of the following conditions precedent: (i)
the Person that acquires a Transferor Interest shall (A) be organized and
existing under the laws of the United States of America or any state or the
District of Columbia thereof, (B) expressly assume, by an agreement supplemental
hereto, executed and delivered to the Trustee, the performance of every covenant
and obligation of the Transferor hereunder and (C) as part of its acquisition of
a Transferor Interest, acquire all rights of the Transferor or any transferee
under this Section 6.05(c) to amounts payable to such Transferor or such
transferee under Sections 5.01(a)(x) and 5.01(g); (ii) the Holder of the
Transferor Interest shall deliver to the Trustee an Officer's Certificate
stating that such transfer and such supplemental agreement comply with this
Section 6.05(c) and that all conditions precedent provided by this subsection
6.05(c) have been complied with and an Opinion of Counsel stating that all
conditions precedent provided by this subsection 6.05(c) have been complied
with, and the Trustee may conclusively rely on such Officer's Certificate, shall
have no duty to make inquiries with regard to the matters set forth therein and
shall incur no liability in so relying; (iii) the Holder of the Transferor
Interest shall deliver to the Trustee a letter from each Rating Agency
confirming that its rating of the Investor Certificates, after giving effect to
such transfer, will not be reduced or withdrawn without regard to the Policy;
(iv) the transferee of the Transferor Interest shall deliver to the Trustee an
Opinion of Counsel to the


                                       55
<PAGE>   60

effect that (a) such transfer will not adversely affect the treatment of the
Investor Certificates after such transfer as debt for federal and applicable
state income tax purposes, (b) such transfer will not result in the Trust being
subject to tax at the entity level for federal or applicable state tax purposes,
(c) such transfer will not have any material adverse impact on the federal or
applicable state income taxation of an Investor Certificateholder or any
Certificate Owner and (d) such transfer will not result in the arrangement
created by this Agreement or any "portion" of the Trust, being treated as a
taxable mortgage pool as defined in Section 7701(i) of the Code; (v) all filings
and other actions necessary to continue the perfection of the interest of the
Trust in the Mortgage Loans and the other property conveyed hereunder shall have
been taken or made and (vi) the transferee shall have assumed the obligations of
the Transferor pursuant to Section 7.07 hereof. Notwithstanding the foregoing,
the requirement set forth in subclause (i)(A) of this Section 6.05(c) shall not
apply in the event the Trustee shall have received a letter from each Rating
Agency confirming that its rating of the Investor Certificates, after giving
effect to a proposed transfer to a Person that does not meet the requirement set
forth in subclause (i)(A), shall no be reduced or withdrawn. Notwithstanding the
foregoing, the requirements set forth in this paragraph (c) shall not apply to
the initial issuance of the Transferor Interest to the Transferor.

      (d) Except for the initial issuance of the Transferor Interest to the
Transferor, no transfer of a Transferor Interest shall be made unless the
Trustee shall have received either (i) a representation letter from the
transferee of such Certificate, acceptable to and in form and substance
satisfactory to the Trustee, to the effect that such transferee is not an
employee benefit plan subject to Section 406 of ERISA, nor a Person acting on
behalf of any such plan, which representation letter shall not be an expense of
the Trustee, (ii) if the purchaser is an insurance company, a representation
that the purchaser is an insurance company which is purchasing such Certificates
with funds contained in an "insurance company general account" (as such term is
defined in Section V(e) of Prohibited Transaction Class Exemption 95-60 ("PTCE
95-60")) and that the purchase and holding of such Certificates are covered
under PTCE 95-60, or (iii) in the case of any Transferor Interest presented for
registration in the name of an employee benefit plan subject to ERISA, and
Section 4975 of the Code (or comparable provisions of any subsequent
enactment's), or a trustee of any such plan, an Opinion of Counsel to the effect
that the purchase or holding of such Certificate will not result in the assets
of the Trust being deemed to be "plan assets" and subject to the prohibited
transaction provisions of ERISA and the Code and will not subject the Trustee to
any obligation in addition to those undertaken in this Agreement, which Opinion
of Counsel shall not be an expense of the Trustee or the Depositor.

      Section 6.06. Appointment of Paying Agent.

      (a) The Paying Agent shall make distributions to Investor
Certificateholders from the Collection Account pursuant to Section 5.01 and
shall report the amounts of such distributions to the Trustee. The duties of the
Paying Agent may include the obligation (i) to withdraw funds from the
Collection Account pursuant to Section 3.03 and for the purpose of making the
distributions referred to above and (ii) to distribute statements and provide
information to Certificateholders as required hereunder. The Paying Agent
hereunder shall at all times be a corporation duly incorporated and validly
existing under the laws of the United States of America or any state thereof,
authorized under such laws to exercise corporate trust powers and subject to
supervision or examination by federal or state authorities. The Paying Agent
shall


                                       56
<PAGE>   61

initially be the Trustee. The Trustee may appoint a successor to act as Paying
Agent, which appointment shall be reasonably satisfactory to the Depositor.

      (b) The Trustee shall cause the Paying Agent (if other than the Trustee)
to execute and deliver to the Trustee an instrument in which such Paying Agent
shall agree with the Trustee that such Paying Agent shall hold all sums, if any,
held by it for payment to the Investor Certificateholders in trust for the
benefit of the Investor Certificateholders entitled thereto until such sums
shall be paid to such Certificateholders and shall agree that it shall comply
with all requirements of the Code regarding the withholding of payments in
respect of Federal income taxes due from Certificate Owners and otherwise comply
with the provisions of this Agreement applicable to it.

      Section 6.07. Acceptance of Obligations. The Transferor, by its acceptance
of the Transferor Interest, agrees to be bound by and to perform all the duties
of the Transferor set forth in this Agreement.

                                   ARTICLE VII

                   The Servicer, the Seller and the Depositor

      Section 7.01. Liability of the Seller, the Servicer and the Depositor. The
Seller and the Servicer shall be liable in accordance herewith only to the
extent of the obligations specifically imposed upon and undertaken by the Seller
or Servicer, as the case may be, herein. The Depositor shall be liable in
accordance herewith only to the extent of the obligations specifically imposed
upon and undertaken by the Depositor.

      Section 7.02. Merger or Consolidation of, or Assumption of the Obligations
of, the Servicer or the Depositor; Assignment of Servicing to an Affiliate. Any
corporation into which the Servicer or the Depositor may be merged or
consolidated, or any corporation resulting from any merger, conversion or
consolidation to which the Servicer or the Depositor shall be a party, or any
corporation succeeding to the business of the Servicer or the Depositor, shall
be the successor of the Servicer or the Depositor, as the case may be,
hereunder, without the execution or filing of any paper or any further act on
the part of any of the parties hereto, anything herein to the contrary
notwithstanding. In addition, so long as Bank One, N.A. or an Affiliate thereof
is the Servicer, upon delivery of prior written notice to the Rating Agencies
and the Credit Enhancer, the Servicer may assign all of its rights and
obligations hereunder to any Eligible Affiliate Servicer provided that such
Eligible Affiliate Servicer agrees to be bound by the obligations of the
Servicer under the Insurance Agreement.

      Section 7.03. Limitation on Liability of the Servicer and Others. Neither
the Servicer nor any of the directors or officers or employees or agents of the
Servicer shall be under any liability to the Trust or the Certificateholders for
any action taken or for refraining from the taking of any action by the Servicer
in good faith pursuant to this Agreement, or for errors in judgment; provided,
however, that this provision shall not protect the Servicer or any such Person
against any liability which would otherwise be imposed by reason of willful
misfeasance,


                                       57
<PAGE>   62

bad faith or gross negligence in the performance of duties of the Servicer or by
reason of reckless disregard of obligations and duties of the Servicer
hereunder. The Servicer and any director or officer or employee or agent of the
Servicer may rely in good faith on any document of any kind prima facie properly
executed and submitted by any Person respecting any matters arising hereunder.
The Servicer and any director or officer or employee or agent of the Servicer
shall be indemnified by the Trust and held harmless against any loss, liability
or expense incurred in connection with any legal action relating to this
Agreement or the Certificates, other than any loss, liability or expense related
to any specific Mortgage Loan or Mortgage Loans (except as any such loss,
liability or expense shall be otherwise reimbursable pursuant to this Agreement)
and any loss, liability or expense incurred by reason of its willful
misfeasance, bad faith or gross negligence in the performance of duties
hereunder or by reason of its reckless disregard of obligations and duties
hereunder. The Servicer shall not be under any obligation to appear in,
prosecute or defend any legal action which is not incidental to duties to
service the Mortgage Loans in accordance with this Agreement, and which in its
opinion may involve it in any expense or liability; provided, however, that the
Servicer may in its sole discretion undertake any such action which it may deem
necessary or desirable in respect of this Agreement, and the rights and duties
of the parties hereto and the interests of the Certificateholders hereunder. In
such event, the reasonable legal expenses and costs of such action and any
liability resulting therefrom shall be expenses, costs and liabilities of the
Trust and the Servicer shall only be entitled to be reimbursed therefor pursuant
to Section 5.01(a)(ix). The Servicer's right to indemnity or reimbursement
pursuant to this Section 7.03 shall survive any resignation or termination of
the Servicer pursuant to Section 7.04 or 8.01 with respect to any losses,
expenses, costs or liabilities arising prior to such resignation or termination
(or arising from events that occurred prior to such resignation or termination).

      Section 7.04. Servicer Not to Resign. Subject to the provisions of Section
7.02, the Servicer shall not resign from the obligations and duties hereby
imposed on it except (i) upon determination that the performance of its
obligations or duties hereunder are no longer permissible under applicable law
or are in material conflict by reason of applicable law with any other
activities carried on by it or its subsidiaries or Affiliates, the other
activities of the Servicer so causing such a conflict being of a type and nature
carried on by the Servicer or its subsidiaries or Affiliates at the date of this
Agreement, (ii) appointment of an Eligible Affiliate Servicer pursuant to
Section 7.02, or (iii) upon satisfaction of the following conditions: (a) the
Servicer has proposed a successor servicer to the Trustee in writing and such
proposed successor servicer is reasonably acceptable to the Trustee; (b) each
Rating Agency shall have delivered a letter to the Trustee prior to the
appointment of the successor servicer stating that the proposed appointment of
such successor servicer as Servicer hereunder will not result in the reduction
or withdrawal of the then current rating of the Investor Certificates without
regard to the Policy; and (c) such proposed successor servicer is reasonably
acceptable to the Credit Enhancer, as evidenced by a letter to the Trustee;
provided, however, that no such resignation by the Servicer shall become
effective until the Trustee or successor servicer designated by the Servicer as
provided above shall have assumed the Servicer's responsibilities and
obligations hereunder or the Trustee shall have designated a successor servicer
in accordance with Section 8.02. An such resignation shall not relieve the
Servicer of responsibility for any of the obligations specified in Sections 8.01
and 8.02 as obligations that survive the resignation or termination of the
Servicer. Any such determination permitting the resignation of the Servicer
pursuant to clause (i) above shall be evidenced by an Opinion of Counsel to such
effect delivered to the Trustee and the


                                       58
<PAGE>   63

Credit Enhancer. The Servicer shall have no claim (whether by subrogation or
otherwise) or other action against any Certificateholders or the Credit Enhance
for any amounts paid by the Servicer pursuant to any provision of this
Agreement.

      Section 7.05. Delegation of Duties. In the ordinary course of business,
the Servicer at any time may delegate any of its duties hereunder to any Person,
including any of its Affiliates, or any subservicer referred to in Section 3.01,
who agrees to conduct such duties in accordance with standards comparable to
those with which the Servicer complies pursuant to Section 3.01. Such delegation
shall not relieve the Servicer of its liabilities and responsibilities with
respect to such duties and shall not constitute a resignation within the meaning
of Section 7.04.

      Section 7.06. Indemnification of the Trust by the Servicer. The Servicer
shall indemnify and hold harmless the Trust and the Trustee from and against any
loss, liability, expense, damage or injury suffered or sustained by reason of
the Servicer's activities or omissions in servicing or administering the
Mortgage Loans that are not in accordance with this Agreement, including, but
not limited to, any judgment, award, settlement, reasonable attorneys' fees and
other costs or expenses incurred in connection with the defense of any actual or
threatened action, proceeding or claim. Any such indemnification shall not be
payable from the assets of the Trust. The provisions of this indemnity shall run
directly to and be enforceable by an injured party subject to the limitations
hereof. The provisions of this Section 7.06 shall survive termination of this
Agreement.

      Section 7.07. Indemnification of the Trust by the Transferor.
Notwithstanding anything to the contrary contained herein, the Transferor (i)
agrees to be liable directly to the injured party without the party necessarily
making a prior claim against the Trust for the entire amount of any losses,
claims, damages, liabilities and expenses of the Trust (other than those
attributable to an Investor Certificateholder in the capacity as an investor in
the Investor Certificates as a result of defaults on the Mortgage Loans) to the
extent that the Transferor would be liable if the Trust were a partnership under
the Delaware Revised Uniform Limited Partnership Act in which the Transferor was
a general partner and (ii) shall indemnify and hold harmless the Trust and the
Trustee from and against any loss, liability, expense, damage, claim or injury
(other than those attributable to an Investor Certificateholder in the capacity
as an investor in the Investor Certificates as a result of defaults on the
Mortgage Loans) arising out of or based on this Agreement by reason of any acts,
omissions, or alleged acts or omissions arising out of activities of the Trust
or the Trustee, or the actions of the Servicer including, but not limited to,
amounts payable to the Servicer pursuant to Section 7.03, any judgment, award,
settlement, reasonable attorneys' fees and other costs or expenses incurred in
connection with the defense of any actual or threatened action, proceeding or
claim; provided that the Transferor shall not indemnify the Trustee (but shall
indemnify any other injured party) if such loss, liability, expense, damage or
injury is due to the Trustee's willful malfeasance, bad faith or gross
negligence or by reason of the Trustee's reckless disregard of its obligations
hereunder. The provisions of this indemnity shall run directly to and be
enforceable by an injured party subject to the limitations hereof.

      Section 7.08. Limitation on Liability of the Transferor. None of the
directors or officers or employees or agents of the Transferor shall be under
any liability to the Trust, the Trustee or the Certificateholders, it being
expressly understood that all such liability is expressly waived and released as
a condition of, and as consideration for, the execution of this Agreement and
the


                                       59
<PAGE>   64

issuance of the Certificates; provided, however, that this provision shall not
protect any such Person against any liability which would otherwise be imposed
by reason of willful misfeasance, bad faith or gross negligence in the
performance of the duties hereunder. Except as provided in Section 7.07, the
Transferor shall not be under any liability to the Trust, the Trustee or the
Certificateholders for any action taken or for refraining from the taking of any
action in its capacity as Transferor pursuant to this Agreement whether arising
from express or implied duties under this Agreement; provided, however, that
this provision shall not protect the Transferor against any liability which
would otherwise be imposed by reason of willful misfeasance, bad faith or gross
negligence in the performance of its duties or by reason of reckless disregard
of its obligations and duties hereunder. The Transferor and any director or
officer or employee or agent of the Transferor may rely in good faith on an
document of any kind prima facie properly executed and submitted by any Person
respecting any matters arising hereunder.

                                  ARTICLE VIII

                              Servicing Termination

      Section 8.01. Events of Servicing Termination. If any one of the following
events ("Events of Servicing Termination") shall occur and be continuing:

            (i) Any failure by the Servicer to deposit in the Collection Account
      any deposit required to be made under the terms of this Agreement which
      continues unremedied for a period of five Business Days after the date
      upon which written notice of such failure shall have been given to the
      Servicer by the Trustee or to the Servicer and the Trustee by the Credit
      Enhancer or Holders of Investor Certificates evidencing Percentage
      Interests aggregating not less than 25%; or

            (ii) Failure on the part of the Servicer duly to observe or perform
      in any material respect any other covenants or agreements of the Servicer
      set forth in the Certificates or in this Agreement, which failure
      continues unremedied for a period of 60 days after the date on which
      written notice of such failure, requiring the same to be remedied, and
      stating that such notice is a "Notice of Default" hereunder, shall have
      been given to the Servicer by the Trustee or to the Servicer and the
      Trustee by the Credit Enhancer or the Holders of Investor Certificates
      evidencing Percentage Interests aggregating not less than 25%; or

            (iii) The entry against the Servicer of a decree or order by a court
      or agency or supervisory authority having jurisdiction in the premises for
      the appointment of a trustee, conservator, receiver or liquidator in any
      insolvency, conservatorship, receivership, readjustment of debt,
      marshalling of assets and liabilities or similar proceedings, or for the
      winding up or liquidation of its affairs, and the continuance of any such
      decree or order unstayed and in effect for a period of 60 consecutive
      days; or

            (iv) The consent by the Servicer to the appointment of a trustee,
      conservator, receiver or liquidator in any insolvency, conservatorship,
      receivership, readjustment of


                                       60
<PAGE>   65

      debt, marshalling of assets and liabilities or similar proceedings of or
      relating to the Servicer or of or relating to substantially all of its
      property; or the Servicer shall admit in writing its inability to pay its
      debts generally as they become due, file a petition to take advantage of
      any applicable insolvency or reorganization statute, make an assignment
      for the benefit of its creditors, or voluntarily suspend payment of its
      obligations;

then, and in each and every such case, so long as an Event of Servicing
Termination shall not have been remedied by the Servicer, either the Trustee,
the Credit Enhancer or the Holders of Investor Certificates evidencing
Percentage Interests aggregating not less than 51%, by notice then given in
writing to the Servicer (and to the Trustee if given by the Credit Enhancer or
the Holders of Investor Certificates) may terminate all of the rights and
obligations of the Servicer as servicer under this Agreement. Any such notice to
the Servicer shall also be given to each Rating Agency and the Credit Enhancer.
On or after the receipt by the Servicer of such written notice, all authority
and power of the Servicer under this Agreement, whether with respect to the
Certificates or the Mortgage Loans or otherwise, shall pass to and be vested in
the Trustee pursuant to and under this Section 8.01; and, without limitation,
the Trustee is hereby authorized and empowered to execute and deliver, on behalf
of the Servicer, as attorney-in-fact or otherwise, any and all documents and
other instruments, and to do or accomplish all other acts or things necessary or
appropriate to effect the purposes of such notice of termination, whether to
complete the transfer and endorsement of each Mortgage Loan and related
documents, or otherwise. The Servicer agrees to cooperate with the Trustee in
effecting the termination of the responsibilities and rights of the Servicer
hereunder, including, without limitation, the transfer to the Trustee for the
administration by it of all cash amounts that shall at the time be held by the
Servicer and to be deposited by it in the Collection Account, or that have been
deposited by the Servicer in the Collection Account or thereafter received by
the Servicer with respect to the Mortgage Loans. All reasonable costs and
expenses (including attorneys' fees) incurred in connection with transferring
the Mortgage Files to the successor Servicer and amending this Agreement to
reflect such succession as Servicer pursuant to this Section 8.01 shall be paid
by the predecessor Servicer (or if the predecessor Servicer is the Trustee, the
initial Servicer) upon presentation of reasonable documentation of such costs
and expenses.

      Notwithstanding the foregoing, a delay in or failure of performance under
Section 8.01(i) for a period of ten Business Days or under Section 8.01(ii) for
a period of 60 Business Days, shall not constitute an Event of Servicing
Termination if such delay or failure could not be prevented by the exercise of
reasonable diligence by the Servicer and such delay or failure was caused by an
act of God or the public enemy, acts of declared or undeclared war, public
disorder, rebellion or sabotage, epidemics, landslides, lightning, fire,
hurricanes, earthquakes, floods or similar causes. The preceding sentence shall
not relieve the Servicer from using its best efforts to perform its respective
obligations in a timely manner in accordance with the terms of this Agreement
and the Servicer shall provide the Trustee, the Transferor, the Credit Enhancer
and the Investor Certificateholders with an Officers' Certificate giving prompt
notice of such failure or delay by it, together with a description of its
efforts to so perform its obligations. The Servicer shall immediately notify the
Trustee in writing of any Events of Servicing Termination.

      Section 8.02. Trustee to Act; Appointment of Successor.

      (a) On and after the time the Servicer receives a notice of termination
pursuant to Section 8.01 or 7.04, the Trustee shall be the successor in all
respects to the Servicer in its capacity as servicer under this Agreement and
the transactions set forth or provided for herein and shall be subject to all
the responsibilities, duties and liabilities relating thereto placed on the
Servicer by the terms and provisions hereof. Notwithstanding the above, if the
Trustee becomes the Servicer hereunder, it shall have no responsibility or
obligation (i) of repurchase or substitution with respect to any Mortgage Loan,
(ii) with respect to any representation or warranty of the Servicer, and (iii)
for any act or omission of either a predecessor or successor Servicer other than
the Trustee. As compensation therefor, the Trustee shall be entitled to such
compensation as the Servicer would have been entitled to hereunder if no such
notice of termination had been given. In addition, the Trustee will be entitled
to compensation with respect to its expenses in connection with conversion of
certain information, documents and record keeping, as provided in Section
7.04(b). Notwithstanding the above, (i) if the Trustee is unwilling to act as
successor Servicer, or (ii) if the Trustee is legally unable so to act, the
Trustee may (in the situation described in clause (i)) or shall (in the
situation described in clause (ii)) appoint or petition a court of competent
jurisdiction to appoint, any established housing and home finance institution,
bank or other mortgage loan or home equity loan servicer having a net worth of
not less than $15,000,000 as the successor to the Servicer hereunder in the
assumption of all or any part of the responsibilities, duties or liabilities of
the Servicer hereunder; provided that any such successor Servicer shall be
acceptable to the Credit Enhancer, as evidenced by the Credit Enhancer's prior
written consent, which consent shall not be unreasonably withheld; and provided
further that the appointment of any such successor Servicer will not result in
the qualification, reduction or withdrawal of the ratings assigned to the
Certificates by the Rating Agencies without regard to the Policy. Pending
appointment of a successor to the Servicer hereunder, unless the Trustee is
prohibited by law from so acting, the Trustee shall act in such capacity as
hereinabove provided. In connection with such appointment and assumption, the
successor shall be entitled to receive compensation out of payments on Mortgage
Loans in an amount equal to the compensation which the Servicer would otherwise
have received pursuant to Section 3.08 (or such lesser compensation as the
Trustee and such successor shall agree). The Trustee and such successor shall
take such action, consistent with this Agreement, as shall be necessary to
effectuate any such succession.

      (b) Any successor, including the Trustee, to the Servicer as servicer
shall during the term of its service as servicer (i) continue to service and
administer the Mortgage Loans for the benefit of Certificateholders and the
Credit Enhancer and (ii) maintain in force a policy or policies of insurance
covering errors and omissions in the performance of its obligations as Servicer
hereunder and a fidelity bond in respect of its officers, employees and agents
to the same extent as the Servicer is so required pursuant to Section 3.12. The
appointment of a successor Servicer shall not affect any liability of the
predecessor Servicer which may have arisen under this Agreement prior to its
termination as Servicer (including, without limitation, any deductible under an
insurance policy pursuant to Section 3.04), nor shall any successor Servicer be
liable for an acts or omissions of the predecessor Servicer or for any breach by
such Servicer of any of their representations or warranties contained herein.

      Section 8.03. Notification to Certificateholders. Upon any termination or
appointment of a successor to the Servicer pursuant to this Article VIII or
Section 7.04, the Trustee shall give prompt written notice thereof to the
Certificateholders at their respective addresses appearing in the Certificate
Register, the Credit Enhancer and each Rating Agency.

                                   ARTICLE IX

                                   The Trustee

      Section 9.01. Duties of Trustee. The Trustee, prior to the occurrence of
an Event of Servicing Termination and after the curing or waiver of all Events
of Servicing Termination which may have occurred, undertakes to perform such
duties and only such duties as are specifically set forth in this Agreement. If
an Event of Servicing Termination has occurred (which has not been cured or
waived) of which a Responsible Officer has knowledge, the Trustee shall exercise
such of the rights and powers vested in it by this Agreement, and use the same
degree of care and skill in their exercise, as a prudent man would exercise or
use under the circumstances in the conduct of his own affairs; provided,
however, that if the Trustee is acting as Servicer it shall use the same degree
of care and skill as is required of the Servicer under this Agreement.

      The Trustee, upon receipt of all resolutions, certificates, statements,
opinions, reports, documents, orders or other instruments furnished to the
Trustee which are specifically required to be furnished pursuant to any
provision of this Agreement, shall examine them to determine whether they
conform to the requirements of this Agreement.

      No provision of this Agreement shall be construed to relieve the Trustee
from liability for its own negligent action, its own negligent failure to act or
its own willful misconduct; provided, however, that:

            (i) prior to the occurrence of an Event of Servicing Termination of
      which a Responsible Officer of the Trustee has knowledge, and after the
      curing or waiver of all such Events of Servicing Termination which may
      have occurred, the duties and obligations of the Trustee shall be
      determined solely by the express provisions of this Agreement, the Trustee
      shall not be liable except for the performance of such duties and
      obligations as are specifically set forth in this Agreement, no implied
      covenants or obligations shall be read into this Agreement against the
      Trustee and, in the absence of bad faith on the part of the Trustee, the
      Trustee may conclusively rely, as to the truth of the statements and the
      correctness of the opinions expressed therein, upon any certificates or
      opinions furnished to the Trustee and conforming to the requirements of
      this Agreement;

            (ii) the Trustee shall not be personally liable for an error of
      judgment made in good faith by a Responsible Officer of the Trustee,
      unless it shall be proved that the Trustee was negligent in ascertaining
      or investigating the facts related thereto;

            (iii) the Trustee shall not be personally liable with respect to any
      action taken, suffered or omitted to be taken by it in good faith in
      accordance with the consent or


                                       63

      direction of the Credit Enhancer or in accordance with the direction of
      the Holders of Investor Certificates evidencing Percentage Interests
      aggregating not less than 51% relating to the time, method and place of
      conducting any proceeding for any remedy available to the Trustee, or
      exercising any trust or power conferred upon the Trustee, under this
      Agreement; and

            (iv) the Trustee shall not be charged with knowledge of any failure
      by the Servicer to comply with the obligations of the Servicer referred to
      in clauses (i) and (ii) of Section 8.01 or of the occurrence of a Rapid
      Amortization Event unless a Responsible Officer of the Trustee at the
      Corporate Trust Office obtains actual knowledge of such failure or the
      Trustee receives written notice of such failure from the Servicer, the
      Credit Enhancer or the Holders of Investor Certificates evidencing
      Percentage Interests aggregating not less than 51%.

      The Trustee shall not be required to expend or risk its own funds or
otherwise incur financial liability in the performance of any of its duties
hereunder, or in the exercise of any of its rights or powers, if there is
reasonable ground for believing that the repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it. None
of the provisions contained in this Agreement shall in any event require the
Trustee to perform, or be responsible for the manner of performance of, any of
the obligations of the Servicer under this Agreement, except during such time,
if any, as the Trustee shall be the successor to, and be vested with the rights,
duties, powers and privileges of, the Servicer in accordance with the terms of
this Agreement and in no event shall it be required to perform or accept
responsibility for the obligations of the Depositor, the Seller or the
Transferor.

      Section 9.02. Certain Matters Affecting the Trustee. Except as otherwise
provided in Section 9.01:

            (i) the Trustee may request and rely upon, and shall be protected in
      acting or refraining from acting upon, any resolution, Officer's
      Certificate, certificate of auditors or any other certificate, statement,
      instrument, opinion, report, notice, request, consent, order, appraisal,
      bond or other paper or document reasonably believed by it to be genuine
      and to have been signed or presented by the proper party or parties;

            (ii) the Trustee may consult with counsel and any written advice of
      such counsel or any Opinion of Counsel shall be full and complete
      authorization and protection in respect of any action taken or suffered or
      omitted by it hereunder in good faith and in accordance with such advice
      or Opinion of Counsel;

            (iii) the Trustee shall be under no obligation to exercise any of
      the rights or powers vested in it by this Agreement, or to institute,
      conduct or defend any litigation hereunder or in relation hereto, at the
      request, order or direction of any of the Certificateholders or the Credit
      Enhancer, pursuant to the provisions of this Agreement, unless such
      Certificateholders or the Credit Enhancer shall have offered to the
      Trustee reasonable security or indemnity against the costs, expenses and
      liabilities which may be incurred therein or thereby; the right of the
      Trustee to perform any discretionary act enumerated in this Agreement
      shall not be construed as a duty, and the Trustee shall not


                                       64
<PAGE>   69

      be answerable for other than its negligence or willful misconduct in the
      performance of any such act; nothing contained herein shall, however,
      relieve the Trustee of the obligations, upon the occurrence of an Event of
      Servicing Termination (which has not been cured or waived) of which a
      Responsible Officer has knowledge, to exercise such of the rights and
      powers vested in it by this Agreement, and to use the same degree of care
      and skill in their exercise as a prudent man would exercise or use under
      the circumstances in the conduct of his own affairs, unless it is acting
      as Servicer;

            (iv) the Trustee shall not be personally liable for any action
      taken, suffered or omitted by it in good faith and believed by it to be
      authorized or within the discretion or rights or owners conferred upon it
      by this Agreement;

            (v) prior to the occurrence of an Event of Servicing Termination and
      after the curing or waiver of all Events of Servicing Termination which
      may have occurred, the Trustee shall not be bound to make any
      investigation into the facts or matters stated in any resolution,
      certificate, statement, instrument, opinion, report, notice, request,
      consent, order, approval, bond or other paper or documents, unless
      requested in writing to do so by Holders of Investor Certificates
      evidencing Percentage Interests aggregating not less than 51%; provided,
      however, that if the payment within a reasonable time to the Trustee of
      the costs, expenses or liabilities likely to be incurred by it in the
      making of such investigation is, in the opinion of the Trustee, not
      reasonably assured to the Trustee by the security afforded to it by the
      terms of this Agreement, the Trustee may require reasonable indemnity
      against such cost, expense or liability as a condition to such proceeding.
      The reasonable expense of every such examination shall be paid by the
      Servicer or, if paid by the Trustee, shall be reimbursed by the Servicer
      upon demand. Nothing in this clause (v) shall derogate from the obligation
      of the Servicer to observe any applicable law prohibiting disclosure of
      information regarding the Mortgagors;

            (vi) the Trustee shall not be accountable, shall have no liability
      and makes no representation as to any acts or omissions hereunder of the
      Servicer until such time as the Trustee may be required to act as Servicer
      pursuant to Section 8.02; and

            (vii) the Trustee may execute any of the trusts or powers hereunder
      or perform any duties hereunder either directly or by or through an
      Affiliate, agents or attorneys or a custodian.

      Section 9.03. Trustee Not Liable for Certificates or Mortgage Loans. The
recitals contained herein and in the Certificates (other than the authentication
of the Trustee on the Certificates) shall be taken as the statements of the
Depositor, and the Trustee assumes no responsibility for the correctness of the
same. The Trustee makes no representations as to the validity or sufficiency of
this Agreement or of the Certificates (other than the signature and
authentication of the Trustee on the Certificates) or of any Mortgage Loan or
Related Document. The Trustee shall not be accountable for the use or
application by the Depositor of any of the Certificates or of the proceeds of
such Certificates, or for the use or application of any funds paid to the
Depositor or the Servicer in respect of the Mortgage Loans or deposited in or
withdrawn from the Collection Account by the Servicer. The Trustee shall at no
time have any responsibility or liability for or with respect to the legality,
validity and enforceability of any


                                       65
<PAGE>   70

Mortgage or any Mortgage Loan, or the perfection and priority of any Mortgage or
the maintenance of any such perfection and priority, or for or with respect to
the sufficiency of the Trust or its ability to generate the payments to be
distributed to Certificateholders under this Agreement, including, without
limitation: the existence, condition and ownership of any Mortgaged Property;
the existence and enforceability of any hazard insurance thereon (other than if
the Trustee shall assume the duties of the Servicer pursuant to Section 8.02);
the validity of the assignment of any Mortgage Loan to the Trustee or of any
intervening assignment; the completeness of any Mortgage Loan; the performance
or enforcement of any Mortgage Loan (other than if the Trustee shall assume the
duties of the Servicer pursuant to Section 8.02); the compliance by the
Depositor, the Seller or the Servicer with any warranty or representation made
under this Agreement or in any related document or the accuracy of any such
warranty or representation prior to the Trustee's receipt of notice or other
discovery of any non-compliance therewith or any breach thereof; any investment
of monies by or at the direction of the Servicer or any loss resulting
therefrom, it being understood that the Trustee shall remain responsible for any
Trust property that it may hold in its individual capacity; the acts or
omissions of any of the Depositor, the Servicer (other than if the Trustee shall
assume the duties of the Servicer pursuant to Section 8.02), any subservicer or
any Mortgagor; any action of the Servicer (other than if the Trustee shall
assume the duties of the Servicer pursuant to Section 8.02), or any subservicer
taken in the name of the Trustee; the failure of the Servicer or any subservicer
to act or perform any duties required of it as agent of the Trustee hereunder;
or any action by the Trustee taken at the instruction of the Servicer (other
than if the Trustee shall assume the duties of the Servicer pursuant to Section
8.02); provided, however, that the foregoing shall not relieve the Trustee of
its obligation to perform its duties under this Agreement. The Trustee shall
have no responsibility for filing any financing or continuation statement in any
public office at any time or to otherwise perfect or maintain the perfection of
any security interest or lien granted to it hereunder (unless the Trustee shall
have become the successor Servicer) or to prepare or file any Securities and
Exchange Commission filing for the Trust or to record this Agreement.

      Section 9.04. Trustee May Own Certificates. The Trustee in its individual
or any other capacity may become the owner or pledgee of Certificates with the
same rights as it would have if it were not Trustee and may transact any banking
and trust business with the Seller, the Servicer, the Credit Enhancer or the
Depositor.

      Section 9.05. Servicer to Pay Trustee's Fees and Expenses; Servicer to
Indemnify. To the extent not otherwise paid pursuant to Section 5.01(a)(i), the
Servicer covenants and agrees to pay to the Trustee from time to time, and the
Trustee shall be entitled to, reasonable compensation (which shall not be
limited by any provision of law in regard to the compensation of a trustee of an
express trust) for all services rendered by it in the execution of the trusts
hereby created and in the exercise and performance of any of the powers and
duties hereunder of the Trustee, and the Servicer will pay or reimburse the
Trustee upon its request for all reasonable expenses, disbursements and advances
incurred or made by the Trustee in accordance with any of the provisions of this
Agreement (including the reasonable compensation and the expenses and
disbursements of its counsel and of all Persons not regularly in its employ)
except any such expense, disbursement or advance as may arise from its
negligence or bad faith or which is the responsibility of Certificateholders
hereunder. The Servicer covenants and agrees to indemnify the Trustee from, and
hold it harmless against, any and all losses, liabilities, damages, claims or
expenses other than those resulting from the negligence or bad faith of the
Trustee. This section


                                       66
<PAGE>   71

shall survive termination of this Agreement or the resignation or removal of any
Trustee hereunder.

      Section 9.06. Eligibility Requirements for Trustee. The Trustee hereunder
shall at all times be a corporation duly incorporated and validly existing under
the laws of the United States of America or any state thereof, authorized under
such laws to exercise corporate trust powers, having a combined capital and
surplus of at least $50,000,000, subject to supervision or examination by
federal or state authority. If such corporation publishes reports of condition
at least annually, pursuant to law or to the requirements of the aforesaid
supervising or examining authority, then for the purposes of this Section 9.06,
the combined capital and surplus of such corporation shall be deemed to be its
combined capital and surplus as set forth in its most recent report of condition
so published. The principal office of the Trustee (other than the initial
Trustee) shall be in a state with respect to which an Opinion of Counsel has
been delivered to such Trustee at the time such Trustee is appointed Trustee to
the effect that the Trust will not be a taxable entity under the laws of such
state. In case at any time the Trustee shall cease to be eligible in accordance
with the provisions of this Section 9.06, the Trustee shall resign immediately
in the manner and with the effect specified in Section 9.07.

      Section 9.07. Resignation or Removal of Trustee. The Trustee may at any
time resign and be discharged from the trusts hereby created by giving written
notice thereof to the Transferor, the Depositor, the Servicer, the Credit
Enhancer and each Rating Agency. Upon receiving such notice of resignation, the
Transferor shall promptly appoint a successor Trustee (approved in writing by
the Credit Enhancer, so long as such approval is not unreasonably withheld) by
written instrument, in duplicate, one copy of which instrument shall be
delivered to the resigning Trustee (who shall deliver a copy to the Servicer)
and one copy to the successor Trustee; provided, however, that any such
successor Trustee shall be subject to the prior written approval of the
Transferor. If no successor Trustee shall have been so appointed and have
accepted appointment within 30 days after the giving of such notice of
resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee.

      If at any time the Trustee shall cease to be eligible in accordance with
the provisions of Section 9.06 and shall fail to resign after written request
therefor by the Transferor or the Credit Enhancer, or if at any time the Trustee
shall be legally unable to act, or shall be adjudged a bankrupt or insolvent, or
a receiver of the Trustee or of its property shall be appointed, or any public
officer shall take charge or control of the Trustee or of its property or
affairs for the purpose of rehabilitation, conservation or liquidation, or if a
tax is imposed or threatens with respect to the Trust Fund by any state in which
the Trustee or the Trust Fund is located (which tax cannot be vacated by the
appointment of a co-Trustee or separate trustee pursuant to Section 9.10), then
the Transferor or the Credit Enhancer may remove the Trustee. If the Transferor
or the Credit Enhancer removes the Trustee under the authority of the
immediately preceding sentence, the Transferor shall promptly appoint a
successor Trustee (approved in writing by the Credit Enhancer, which approval
shall not be unreasonably withheld) by written instrument, in duplicate, one
copy of which instrument shall be delivered to the Trustee so removed and one
copy to the successor Trustee.


                                       67
<PAGE>   72

      The Holders of Investor Certificates evidencing Percentage Interests
aggregating over 50% of all Investor Certificates may at any time remove the
Trustee by written instrument or instruments delivered to the Servicer, the
Transferor and the Trustee; the Transferor shall thereupon use its best efforts
to appoint a successor trustee in accordance with this Section.

      Any resignation or removal of the Trustee and appointment of a successor
Trustee pursuant to any of the provisions of this Section 9.07 shall not become
effective until acceptance of appointment by the successor Trustee as provided
in Section 9.08.

      Section 9.08. Successor Trustee. Any successor Trustee appointed as
provided in Section 9.07 shall execute, acknowledge and deliver to the
Transferor, the Depositor, the Servicer, the Credit Enhancer and to its
predecessor Trustee an instrument accepting such appointment hereunder, and
thereupon the resignation or removal of the predecessor Trustee shall become
effective and such successor Trustee, without any further act, deed or
conveyance, shall become fully vested with all the rights, powers, duties and
obligations of its predecessor hereunder, with like effect as if originally
named as Trustee. The Transferor, the Depositor, the Servicer and the
predecessor Trustee shall execute and deliver such instruments and do such other
things as may reasonably be required for fully and certainly vesting and
confirming in the successor Trustee all such rights, powers, duties and
obligations.

      No successor Trustee shall accept appointment as provided in this Section
9.08 unless at the time of such acceptance such successor Trustee shall be
eligible under the provisions of Section 9.06.

      Upon acceptance of appointment by a successor Trustee as provided in this
Section 9.08, the successor Trustee shall mail notice of the succession of such
Trustee hereunder to all Holders of Certificates at their addresses as shown in
the Certificate Register and to each Rating Agency. If the Servicer fails to
mail such notice within 30 days after acceptance of appointment by the successor
Trustee, the successor Trustee shall cause such notice to be mailed at the
expense of the Servicer.

      Section 9.09. Merger or Consolidation of Trustee. Any Person into which
the Trustee may be merged or converted or with which it may be consolidated, or
any Person resulting from any merger, conversion or consolidation to which the
Trustee shall be a party, or any Person succeeding to all or substantially all
of the business of the Trustee, shall be the successor of the Trustee hereunder,
provided such Person shall be eligible under the provisions of Section 9.06,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto, any thing herein to the contrary notwithstanding.

      Section 9.10. Appointment of Co-Trustee or Separate Trustee.
Notwithstanding any other provisions of this Agreement, at any time, for the
purpose of meeting any legal requirements of any jurisdiction in which any part
of the Trust or any Mortgaged Property may at the time be located, the
Transferor and the Trustee acting jointly shall have the power and shall execute
and deliver all instruments necessary to appoint one or more Persons approved by
the Credit Enhancer to act as co-trustee or co-trustees, jointly with the
Trustee, or separate trustee or separate trustees, of all or any part of the
Trust, and to vest in such Person or Persons, in such capacity and for the
benefit of the Certificateholders, such title to the Trust, or any part thereof,


                                       68
<PAGE>   73

and, subject to the other provisions of this Section 9.10, such powers, duties,
obligations, rights and trusts as the Transferor and the Trustee may consider
necessary or desirable. Any such co-trustee or separate trustee shall be subject
to the written approval of the Servicer. If the Transferor shall not have joined
in such appointment within 15 days after the receipt by it of a request so to
do, or in the case an Event of Servicing Termination shall have occurred and be
continuing, the Trustee alone shall have the power to make such appointment. No
co-trustee or separate trustee hereunder shall be required to meet the terms of
eligibility as a successor trustee under Section 9.06 and no notice to
Certificateholders of the appointment of any co-trustee or separate trustee
shall be required under Section 9.08. The Servicer shall be responsible for the
fees of any co-trustee or separate trustee appointed hereunder.

Every separate trustee and co-trustee shall, to the extent permitted by law, be
appointed and act subject to the following provisions and conditions:

            (i) all rights, powers, duties and obligations conferred or imposed
      upon the Trustee shall be conferred or imposed upon and exercised or
      performed by the Trustee and such separate trustee or co-trustee jointly
      (it being understood that such separate trustee or co-trustee is not
      authorized to act separately without the Trustee joining in such act),
      except to the extent that under any law of any jurisdiction in which any
      particular act or acts are to be performed (whether as Trustee hereunder
      or as successor to the Servicer hereunder), the Trustee shall be
      incompetent or unqualified to perform such act or acts, in which event
      such rights, powers, duties and obligations (including the holding of
      title to the Trust or any portion thereof in any such jurisdiction) shall
      be exercised and performed singly by such separate trustee or co-trustee,
      but solely at the direction of the Trustee;

            (ii) no trustee hereunder shall be held personally liable by reason
      of any act or omission of any other trustee hereunder; and

            (iii) the Servicer and the Trustee acting jointly may at any time
      accept the resignation of or remove any separate trustee or co-trustee
      except that following the occurrence of an Event of Servicing Termination,
      the Trustee acting alone may accept the resignation or remove any separate
      trustee or co-trustee.

      Any notice, request or other writing given to the Trustee shall be deemed
to have been given to each of the then separate trustees and co-trustees, as
effectively as if given to each of them. Every instrument appointing any
separate trustee or co-trustee shall refer to this Agreement and the conditions
of this Article IX. Each separate trustee and co-trustee, upon its acceptance of
the trusts conferred, shall be vested with the estates or property specified in
its instrument of appointment, either jointly with the Trustee or separately, as
may be provide therein, subject to all the provisions of this Agreement,
specifically including every provision of this Agreement relating to the conduct
of, affecting the liability of, or affording protection to, the Trustee. Every
such instrument shall be filed with the Trustee and a copy thereof given to the
Transferor and the Servicer.

      Any separate trustee or co-trustee may, at any time, constitute the
Trustee, its agent or attorney-in-fact, with full power and authority, to the
extent not prohibited by law, to do any lawful act under or in respect of this
Agreement on its behalf and in its name. If any separate


                                       69
<PAGE>   74

trustee or co-trustee shall die, become incapable of acting, resign or be
removed, all of it estates, properties, rights, remedies and trusts shall vest
in and be exercised by the Trustee, to the extent permitted by law, without the
appointment of a new or successor Trustee.

      Section 9.11. Limitation of Liability. The Certificates are executed by
the Trustee, not in its individual capacity but solely as Trustee of the Trust,
in the exercise of the powers an authority conferred and vested in it by the
Trust Agreement. Each of the undertakings and agreements made on the part of the
Trustee in the Certificates is made and intended not as a personal undertaking
or agreement by the Trustee but is made and intended for the purpose of binding
only the Trust.

      Section 9.12. Trustee May Enforce Claims Without Possession of
Certificates. All rights of action and claims under this Agreement or the
Certificates may be prosecuted and enforced by the Trustee without the
possession of any of the Certificates or the production thereof in any
proceeding relating thereto, and such proceeding instituted by the Trustee shall
be brought in it own name or in its capacity as Trustee. Any recovery of
judgment shall, after provision for the payment of the reasonable compensation,
expenses, disbursement and advances of the Trustee, its agents and counsel, be
for the ratable benefit or the Certificateholders in respect of which such
judgment has been recovered.

      Section 9.13. Suits for Enforcement. In case an Event of Servicing
Termination or other default by the Servicer, the Transferor, the Depositor or
the Seller hereunder shall occur an be continuing, the Trustee, in its
discretion, may proceed to protect and enforce its rights and the rights of the
Investor Certificateholders under this Agreement by a suit, action or proceeding
in equity or at law or otherwise, whether for the specific performance of any
covenant or agreement contained in this Agreement or in aid of the execution of
any power granted in this Agreement or for the enforcement of any other legal,
equitable or other remedy, as the Trustee, being advised by counsel, shall deem
most effectual to protect and enforce any of the rights of the Trustee and the
Certificateholder.

                                   Termination

      Section 10.01. Termination.

      (a) The respective obligations and responsibilities of the Seller, the
Servicer, the Depositor, the Transferor and the Trustee created hereby (other
than the obligation of the Trustee to make certain payments to
Certificateholders after the final Distribution Date and the obligation of the
Servicer to send certain notices as hereinafter set forth) shall terminate upon
the last action required to be taken by the Trustee on the final Distribution
Date pursuant to this Article X following the later of (A) payment in full of
all amounts owing to the Credit Enhancer and (B) the earliest of (i) the
transfer, under the conditions specified in Section 10.01(b), to the Transferor
of the Investor Certificateholders' interest in each Mortgage Loan and all
property acquired in respect of any Mortgage Loan remaining in the Trust for an
amount equal to the sum of (w) the Investor Certificate Principal Balance, (x)
accrued and unpaid Investor Certificate Interest through the day preceding the
final Distribution Date, and (y) interest accrued on any Unpaid Investor
Certificate Interest Shortfall, to the extent legally permissible, (ii) the day
following the Distribution Date on which the distribution made to Investor
Certificateholders has reduced the Investor Certificate Principal Balance to
zero, (iii) the final payment or other liquidation of the last Mortgage Loan
remaining in the Trust (including without limitation the disposition of the
Mortgage Loans pursuant to Section 10.02) or the disposition of all property
acquired upon foreclosure or deed in lieu of foreclosure of any Mortgage Loan
(iv) the Distribution Date in____ _____; provided, however, that in no event
shall the trust created hereby continue beyond the expiration of 21 years from
the date of the last survivor descendants of Joseph P. Kennedy, the late
ambassador of the United States to the Court of St. James, living on the date
hereof. Upon termination in accordance with clause (i) or (ii) of this Section
10.01, the Trustee shall execute such documents and instruments of transfer
presented by the Transferor, in each case without recourse, representation or
warranty, and take such other actions as the Transferor may reasonably request
to effect the transfer of the Mortgage Loans to the Transferor.

      (b) The Transferor shall have the right to exercise the option to effect
the transfer to the Transferor of each Mortgage Loan pursuant to Section
10.01(a) above on any Distribution Date on or after the Distribution Date
immediately prior to which the Investor Certificate Principal Balance is less
than ____ percent (_%) of the Original Investor Certificate Principal Balance
and all amounts due and owing to the Credit Enhancer for unpaid premiums and
unreimbursed draws on the Policy, together with interest thereon as provided
under the Insurance Agreement, have been paid.

      (c) Notice of any termination, specifying the Distribution Date (which
shall be a date that would otherwise be a Distribution Date) upon which the
Investor Certificateholders may surrender their Investor Certificates to the
Trustee for payment of the final distribution and cancellation, shall be given
promptly by the Trustee (upon receipt of written directions from the Transferor,
if the Transferor is exercising its right to transfer of the Mortgage Loans,
given not later than the first day of the month preceding the month of such
final distribution) to the Credit Enhancer and to the Servicer by letter to
Investor Certificateholders mailed not earlier than the


                                       71
<PAGE>   76

15th day and not later than the 25th day of the month next preceding the month
of such final distribution specifying (i) the Distribution Date upon which final
distribution of the Investor Certificates will be made upon presentation and
surrender of Investor Certificates at the office or agency of the Trustee
therein designated, (ii) the amount of any such final distribution and (iii)
that the Record Date otherwise applicable to such Distribution Date is not
applicable, distributions being made only upon presentation and surrender of the
Investor Certificates at the office or agency of the Trustee therein specified.
In the event written directions are delivered by the Transferor to the Trustee
as described in the preceding sentence, the Transferor shall deposit in the
Collection Account on or before the Distribution Date for such final
distribution in immediately available funds an amount which, when added to the
funds on deposit in the Collection Account that are payable to the Investor
Certificateholders, will be equal to the retransfer amount for the Mortgage
Loans computed as above provided.

      (d) Upon presentation and surrender of the Investor Certificates, the
Trustee shall cause to be distributed to the Holders of Investor Certificates on
the Distribution Date for such final distribution, in proportion to the
Percentage Interests of their respective Investor Certificates and to the extent
that funds are available for such purpose, an amount equal to (i) if such final
distribution is not being made pursuant to the transfer to the Transferor
pursuant to Section 10.01(a)(i), the amount required to be distributed to
Investor Certificateholders pursuant to Section 5.01 for such Distribution Date
and (ii) if such final distribution is being made pursuant to such retransfer,
the amount specified in Section 10.01(a)(i). The distribution on such final
Distribution Date pursuant to a retransfer pursuant to Section 10.01(a)(i) shall
be in lieu of the distribution otherwise required to be made on such
Distribution Date in respect of the Certificates. On the final Distribution Date
prior to having made the distributions called for above, the Trustee shall,
based upon the information set forth in the Servicing Certificate for such

Agreement.

      (e) In the event that all of the Investor Certificateholders shall not
surrender their Investor Certificates for final payment and cancellation on or
before such final Distribution Date, the Trustee shall on such date cause all
funds in the Collection Account not distributed in final distribution to
Investor Certificateholders to be withdrawn therefrom and credited to the

contact the remaining Investor Certificateholders concerning surrender of their
Investor Certificates, and the cost thereof shall be aid out of the funds on

reasonable. The provisions of Sections 11.01 and 11.02 shall not be deemed to be
mutually exclusive.

      (b) The proceeds from the sale, disposition or liquidation of the Mortgage
Loans pursuant to Section 11.02(a) above shall be treated as collections on the
Mortgage Loans received during the Rapid Amortization Period; provided, however,

distributed to the Investor Certificateholders the Trust shall terminate.

                                   ARTICLE XII

each case without the consent of any of the Certificateholders, but only with

withheld), (i) to cure any ambiguity, (ii) to correct any defective provisions
or to correct or supplement any provisions herein that may be inconsistent with
any other provisions herein, (iii) to add to the duties of the Transferor or the
Servicer, (iv) to add any other provisions with respect to matters or questions
arising under this Agreement or the Policy, as the case may be, which shall not
be inconsistent with the provisions of this Agreement, (v) to add or amend any
provisions of this Agreement as required by any Rating Agency or any other
nationally recognized statistical rating organization in order to maintain or
improve any rating of the Investor Certificates (it being understood that, after
obtaining the ratings in effect on the Closing Date, neither the Trustee, the
Seller, the Depositor nor the Servicer is obligated to


                                       75
<PAGE>   80

obtain, maintain or improve any such rating), (vi) to add or amend any
provisions of this Agreement to correct or cure any defective provision or
ambiguity as a result of a transfer of the Transferor Interest pursuant to
Section 6.05, or (vii) to comply with any requirement imposed by the Code;
provided, however, that such action shall not, as evidenced by an Opinion of
Counsel, materially and adversely affect the interests of any Certificateholder
or the Credit Enhancer; and provided, further, that the amendment shall not be
deemed to adversely affect in any material respect the interests of the
Certificateholders and no opinion referred to in the preceding proviso shall be
required to be delivered if the Person requesting the amendment obtains a letter
from each Rating Agency stating that the amendment would not result in the
downgrading or withdrawal of the respective ratings then assigned to the
Investor Certificates without regard to the Policy. Notwithstanding the
foregoing, any amendment pursuant to clause (viii) above shall be permissible
only upon receipt of a letter from each Rating Agency stating that the amendment
would not result in the downgrading or withdrawal of the respective ratings then
assigned to the Investor Certificateholders without regard to the Policy.

      This Agreement also may be amended from time to time by the Servicer, the
Seller, the Depositor and the Trustee, and the Servicer and the Credit Enhancer,

provisions to or changing in any manner or eliminating any of the provisions of
this Agreement or of modifying in any manner the rights of the
Certificateholders; provided, however, that no such amendment shall (i) reduce
in any manner the amount of, or delay the timing of, payments on the
Certificates or distributions or payments under the Policy which are required to
be made on any Certificate without the consent of the Holder of such Certificate
or (ii) reduce the aforesaid percentage required to consent to any such
amendment, without the consent of the Holders of all Certificates then
outstanding or (iii) adversely effect in any material respect the interests of
the Credit Enhancer.

amended to permit the Trust to qualify as other than an association taxable as a
corporation (if the Trust is not otherwise treated as a security device) and the
Trustee receives an Officer's Certificate from the Servicer of such amendment,
the Trust will make an election and Sections 7.07 and 11.02(a) shall not be
given effect.

      Notwithstanding the foregoing, the Agreement may not be amended unless, in
connection with such amendment, an Opinion of Counsel is furnished to the
Trustee that such amendment will not (i) adversely affect the status of the
Investor Certificates as debt; (ii) result in the Trust being taxable at the
entity level; or (iii) result in the Trust being classified as a taxable
mortgage pool (as defined in Section 7701(i) of the Code).

the Policy to which the Credit Enhancer was require to consent, either the
Transferor, if the Transferor requested the amendment, or the Servicer, if the
Servicer requested the amendment, shall reimburse the Credit Enhancer for the
reasonable out-of-pocket costs and expenses incurred by the Credit Enhancer in
connection with such amendment.

any such amendment shall furnish written notification of the substance of such
amendment to each Rating Agency. In addition, promptly after the execution of
any such amendment made with the consent of the Investor Certificateholders, the
Trustee shall furnish written notification of the substance of such amendment to
each Investor Certificateholder and fully executed original counterparts of the
instruments effecting such amendment to the Credit Enhancer.

      It shall not be necessary for the consent of Investor Certificateholders
under this Section 12.01 to approve the particular form of any proposed
amendment or consent, but it shall be sufficient if such consent shall approve
the substance thereof. The manner of obtaining such consents and of evidencing
the authorization of the execution thereof by Certificateholders shall be
subject to such reasonable requirements as the Trustee may prescribe.

      In executing any amendment permitted by this Section 12.01, the Trustee
shall be entitled to receive, and shall be fully protected in relying upon, an
Opinion of Counsel stating that such amendment is authorized or permitted hereby

amendment have been satisfied. The Trustee may, but shall not be obligated to,

beneficially affects the interests of Investor Certificateholders. The Investor
Certificateholders requesting such recordation shall bear all costs and expenses

such recordation so affects the interests of the Certificateholders.

herein provided and for other purposes, this Agreement may be executed
simultaneously in any number of counterparts, each of which counterparts shall
be deemed to be an original, and such counterparts shall constitute but one and
the same instrument.

incapacity of any Investor Certificateholder shall not operate to terminate this
Agreement or the Trust, nor entitle such Investor Certificateholder's legal
representatives or heirs to claim an accounting or to take any action or
commence any proceeding in any court for a partition or winding up of the Trust,
nor otherwise affect the rights, obligations and liabilities of the parties
hereto or any of them.

      No Certificateholder shall have any right to vote (except as provided in
Sections 8.01, 9.01, 9.02, 11.01 and 12.01) or in any manner otherwise control
the operation and management of the Trust, or the obligations of the parties
hereto, nor shall any thing herein set forth, or contained in the terms of the
Certificates, be construed so as to constitute the Certificateholders from time
to time as partners or members of an association; nor shall any Investor


                                       77

of any provisions of this Agreement to institute any suit, action or proceeding
in equity or at law upon or under or with respect to this Agreement, unless such
Holder previously shall have given to the Trustee a written notice of default
and of the continuance thereof, as hereinbefore provided, and unless also the
Holders of Investor Certificates evidencing Percentage Interests aggregating not
less than 51% shall have made written request upon the Trustee to institute such
action, suit or proceeding in its own name as Trustee hereunder and shall have
offered to the Trustee such reasonable indemnity as it may require against the
costs, expenses and liabilities to be incurred therein or thereby, and the
Trustee, for 60 days after its receipt of such notice, request and offer of
indemnity, shall have neglected or refused to institute any such action, suit or
proceeding; it being understood and intended, and being expressly covenanted by
each Certificateholder with every other Certificateholder and the Trustee, that
no one or more Holders of Certificates shall have any right in any manner
whatever by virtue or by availing itself or themselves of any provisions of this
Agreement to affect, disturb or prejudice the rights of the Holders of any other
of the Certificates, or to obtain or seek to obtain priority over or preference
to any other such Holder, or to enforce any right under this Agreement, except
in the manner herein provided and for the equal, ratable and common benefit of
all Certificateholders. For the protection and enforcement of the provisions of
this Section 12.03, each and every Certificateholder and the Trustee shall be
entitled to such relief as can be given either at law or in equity.

Ladies and Gentlemen:

      We have acted as special counsel to Banc One ABS Corporation (the
"Registrant"), in connection with the preparation and filing with the Securities
and Exchange Commission (the "Commission") on July 22, 1998 of a Registration
Statement on Form S-3 (the "Registration Statement"), in connection with the
registration under the Securities Act of 1933, as amended (the "Act") of
Asset-Backed Securities (the "Securities"). The Securities are issuable in
series (each, a "Series") under either a separate Pooling and Servicing
Agreement, Trust Agreement or Indenture (each, an "Agreement") by and among the
Registrant, the Servicer named therein and the Trustee named therein. The
Securities of each Series are to be sold as set forth in the Registration
Statement, any amendment thereto, and the prospectus and prospectus supplement
relating to such Series.

      We have examined such instruments, documents and records as we deemed
relevant and necessary as a basis of our opinion hereinafter expressed. In such
examination, we have assumed the following: (a) the authenticity of original
documents and the genuineness of all signatures; (b) the conformity to the
originals of all documents submitted to us as copies; and (c) the truth,
accuracy and completeness of the information, representations and warranties
contained in the records, documents, instruments and certificates we have
reviewed.

      Based on such examination, we are of the opinion that when the issuance of
each Series of Securities has been duly authorized by appropriate corporate
action and the Securities of such Series have been duly executed, authenticated
and delivered in accordance with the Agreement relating to such Series and sold
in the manner described in the Registration Statement and the prospectus and
prospectus supplement relating thereto, the Securities of such Series will be
legally issued, fully paid, binding obligations of the trust created by each
Agreement and the holders of the Securities of such Series will be entitled to
the benefits of the related Agreement, except as enforcement thereof may be
limited by applicable bankruptcy, insolvency, reorganization, arrangement,
fraudulent conveyance, moratorium, or other laws relating to or affecting the
rights of creditors generally and

general principles of equity, including without limitation, concepts of
materiality, reasonableness, good faith and fair dealing, and the possible
unavailability of specific performance or injunctive relief, regardless of
whether such enforceability is considered in a proceeding in equity or at law.

      In rendering the foregoing opinions, we express no opinion as to the laws
of any jurisdiction other than the State of New York and the Federal laws of the
United States of America.

      We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the use of our name wherever appearing in the
Registration Statement and the prospectus contained therein, as supplemented by
the prospectus supplement related to a series of Securities. In giving such
consent, we do not consider that we are "experts," within the meaning of the
term as used in the Act or the rules and regulations of the Commission issued
thereunder, with respect to any part of the Registration Statement, including
this opinion as an exhibit or otherwise.


                                    Very truly yours,

                                    /s/ ORRICK, HERRINGTON & SUTCLIFFE LLP

Banc One ABS Corporation

Ladies and Gentlemen:

         We have advised Banc One ABS Corporation (the "Registrant") with
respect to certain federal income tax aspects of the issuance by the Registrant
of its Asset-Backed Securities, issuable in series (the "Securities"). In
connection therewith we have reviewed the description of selected federal income
tax consequences to holders of the Securities that appears under the heading
"Certain Federal Income Tax Consequences" in the prospectus (the "Prospectus")
forming a part of the Registration Statement on Form S-3 filed on July 22, 1998
(the "Registration Statement") with the Securities and Exchange Commission under
the Securities Act of 1933, as amended (the "Act"). Such description does not
purport to discuss all possible income tax ramifications of the proposed
issuance, but with respect to those tax consequences which are discussed, in our
opinion, to the extent the description is a discussion of law or legal
conclusions, such description is true and correct in all material respects.

         This opinion is based on the facts and circumstances set forth in the
Prospectus and in the other documents reviewed by us. Our opinion as to the
matters set forth herein could change with respect to a particular series of
Securities as a result of changes in facts and circumstances, changes in the
terms of the documents reviewed by us, or changes in the law subsequent to the
date hereof. As the Registration Statement contemplates series of Securities
with numerous different characteristics, the particular characteristics of each
series of Securities must be considered in determining the applicability of this
opinion to a particular series of Securities.

         We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the use of our name wherever appearing in the
Registration Statement and the Prospectus contained therein, as supplemented by
the prospectus supplement relating to a series of Securities. In giving such
consent, we do not consider that we are "experts,"

within the meaning of the term as used in the Act or the rules and regulations
of the Commission issued thereunder, with respect to any part of the
Registration Statement, (including this opinion) as an exhibit or otherwise.
