                                   ARTICLE I.

                       CREATION OF THE SERIES 1998-1 NOTES

            SECTION 1.01 Designation. There is hereby created a Series of Notes
to be issued pursuant to the Master Agreement and this Series 1998-1 Supplement
to be known as "Advanta Equipment Receivables Asset-Backed Notes, Series 1998-1"
(the "Series 1998-1 Notes"). The Series Obligors with respect to the Series
1998-1 Notes are ALRC IV and ALRC V, jointly and severally.

            SECTION 1.02 Pledge of Series 1998-1 Trust Estate. The Series
Obligors hereby pledge to the Trustee for the benefit of the Series 1998-1
Noteholders, and the Trustee hereby accepts the pledge of, all of the Series
Obligors' now owned and existing and hereafter acquired or arising right, title
and interest in and to (1) each and every Contract (including Additional
Contracts) now or hereafter listed on each Pledge Notice delivered to the
Trustee in connection with this Series 1998-1 Supplement (each such Contract, a
"Series 1998-1 Contract"), (2) all Collections received after the related
Cut-Off Date, and all Related Security associated therewith, (3) all balances,
instruments, monies and other securities and investments from time to time in
the Series 1998-1 Facility Account, to the extent the same represent Collections
or proceeds of Series 1998-1 Contracts or earnings with respect thereto,
together with the Reserve Account, the Residual Account and the Additional
Property Funding Account (4) each Series 1998-1 
   5
Contribution Agreement Supplement and all of their rights (directly or through
the Obligors' Agent) to enforce the provisions of, and to benefit from the
representations, warranties and covenants made in each Series 1998-1
Contribution Agreement Supplement and in the Contribution Agreement, but only
insofar as such rights relate to the Series 1998-1 Trust Estate, (5) all
security interests of the Series Obligors in the Equipment not owned by the
Series Obligors, and all Equipment owned by the Series Obligors, in each case
associated with the Series 1998-1 Contracts, (6) any Crossover Amounts allocated
to the Series 1998-1 Trust Estate from another Series and (7) all proceeds of
each of the foregoing, but excluding any obligations of the Series Obligors, if
any, under each Series 1998-1 Contribution Agreement Supplement and excluding
any Insurance Premiums, taxes, late charge fees, Initial Unpaid Amounts and
Security Deposits, all in accordance with, and for the purposes set forth in,
this Series 1998-1 Supplement (such property, the "Series 1998-1 Trust Estate").

            It is the intention of the Series Obligors, which intention is
acknowledged by the Trustee, that this Series 1998-1 Supplement, together with
the Master Agreement, shall be deemed to be a security agreement within the
meaning of Article 8 and Article 9 of the Uniform Commercial Code as in effect
in the States of New York, Nevada and Delaware and the pledge provided for
herein shall be deemed to be a grant by the Series Obligors to the Trustee for
the benefit of the Series 1998-1 Noteholders of (A) a valid first priority
perfected security interest in all of the Series Obligors' right, title and
interest in and to the Series 1998-1 Trust Estate, except for the Equipment not
owned by the Series Obligors, and (B) a valid assignment of their security
interests in the Equipment not owned by the Series Obligors. The Series Obligors
hereby grant such a security interest and assign such security interest, in each
case to the Trustee to secure the obligations of the Series Obligors to the
Trustee and the Series 1998-1 Noteholders hereunder.

            In the case of any Series 1998-1 Contract which has been prepaid in
full during the period from the related Cut-Off Date to the related Pledge Date,
the Series Obligors shall, on the related Pledge Date, deposit the Prepayment

Series 1998-1 Contract to the Trustee.

            SECTION 1.03 Pledges of Additional Property. (a) During the
Interest-Only Period, the Series Obligors shall, to the extent necessary, such
that the Additional Properly Funding Requirement is zero at the close of each
Payment Date during the Interest Only Period, upon providing a Pledge Notice not
less than three (3) Business Days' prior to the proposed Pledge Date, pledge
additional property to the Trustee to be held in trust as part of the Series
1998-1 Trust Estate. Each Pledge Notice shall specify:

                 (i) the proposed Pledge Date, which shall be a Payment Date, 
      and

                 (ii) the related List of Contracts.

      Series Obligor will use its reasonable best efforts to acquire from ABS,
      during the Interest-Only Period, a sufficient volume of Eligible Contracts
      such that a Required Amortization Event of the type described in paragraph
      (ii) of the definition thereof does not occur.

            SECTION 1.04 Custody of the Series 1998-1 Trust Estate. For the
avoidance of doubt, the parties agree that notwithstanding the use of the terms
"deposit", "deposited", "transfer" and "transferred" in this Series 1998-1
Supplement, the Trustee will not take physical possession of any of the Series
1998-1 Trust Estate (other than the amounts on deposit in the Series 1998-1
Accounts) pursuant to the terms hereof. Instead, the Servicer will hold the
Series 1998-1 Trust Estate (other than the amounts on deposit in the Series
1998-1 Accounts) as custodian on behalf of the Trustee.

            SECTION 1.05 Conditions to Issuance. As conditions to the execution

power independently to enforce all of the Series Obligors' rights against the

            SECTION 1.07 Liabilities of the Trustee and Parties to the Master

Limitations Thereon. The obligations evidenced by the Series 1998-1 Notes
provide recourse only to the Series 1998-1 Trust Estate and provide no recourse
against either of the Series Obligors generally, the Contributor, the Servicer,
the Trustee, or any other Person.

            (a) The Series Obligors, the Servicer and the Contributor shall not
      be liable to the Trustee except as expressly provided herein, and, with
      respect to the Contributor, as provided in the Contribution Agreement. The
      Series Obligors, the Contributor and the Servicer shall not be liable to
      the Noteholders except, with

   8
      respect to the Series Obligors and the Servicer, for the non-performance
      of obligations expressly undertaken by them pursuant hereto, and, with
      respect to the Contributor, as expressly provided in the Contribution
      Agreement. Without limiting the generality of the foregoing, if any User
      fails to pay any Scheduled Payment, Final Contract Payment, exercised
      Purchase Option Payment or other amounts due under a Series 1998-1
      Contract, then neither the Trustee nor the Noteholders will have any
      recourse against the Series Obligors, the Contributor or the Servicer for
      such Scheduled Payment, Final Contract Payment, exercised Purchase Option
      Payment, other amounts due under the Series 1998-1 Contract or any losses,
      damages, claims, liabilities or expenses incurred by the Trustee or any
      Series 1998-1 Noteholder as a direct or indirect result thereof.

            (b) The Trustee agrees that in the event of a default by a User
      under the terms of a Series 1998-1 Contract, which default is not cured
      within any applicable cure period set forth in such Series 1998-1
      Contract, the Trustee and the Series 1998-1 Noteholders shall be expressly
      limited to the sources of payment specified herein. In addition, the
      Trustee shall have the right to exercise the rights of the Contributor
      (which rights have been assigned to the Series Obligors and then to the
      Trustee) under the Series 1998-1 Contracts, the Insurance Policies, any
      document in any Contract File and any Related Document in the name of the
      Trustee and the Series 1998-1 Noteholders, either directly or through the
      Servicer as agent, and the Trustee is hereby directed by the Series
      Obligors to exercise such rights; provided, however, that the Trustee
      shall not be required to take any action pursuant to this Section 1.07
      except upon written instructions from the Servicer and to the extent it is
      fully indemnified to its reasonable satisfaction therefor.

            (c) A carbon, photographic or other reproduction of the Master
      Agreement, this Series 1998-1 Supplement or any financing statement is
      sufficient as a financing statement in any State.

The receipt of the Series 1998-1 Trust Estate by the Trustee (through possession
thereof by the Servicer acting as custodian) does not constitute and is not
intended to result in an assumption by the Trustee or any Series 1998-1
Noteholder of any obligation (except for the obligation not to disturb a User's
right of quiet enjoyment) of the Contributor, either Series Obligor or the
Servicer to any User or other Person in connection with the Equipment, the
Series 1998-1 Contracts, the Insurance Policies, any document in the Contract
Files or any Related Document.

            (d) The Trustee shall promptly send to each Series 1998-1 Noteholder

      Amortization Event; and

                        (viii) Notice of the occurrence of any Event of Servicer
      Termination or of any Event of Default;

provided, however, that in each case the Trustee shall only be required to send
such notices and other items to the Series 1998-1 Noteholders to the extent that
the Trustee has itself received the related information and the Series 1998-1
Noteholders have not already 


                                       31

direction of the Servicer, shall comply with all federal withholding
requirements respecting payments (or advances thereof) to Series 1998-1
Noteholders as may be applicable to instruments constituting indebtedness for
federal income tax purposes. Any amounts so withheld shall be treated as having
been paid to the related Series 1998-1 Noteholder for all purposes of this
Series 1998-1 Supplement. In no event shall the consent of Noteholders be
required for any withholding.

            SECTION 3.08 Servicer Advances. No later than one Business Day
preceding each Payment Date, the Servicer shall make a Servicer Advance for each
Series 1998-1 Contract which is a Delinquent Contract with respect to each
overdue payment as of the related Calculation Date in an amount equal to the
Scheduled Payments, or portion thereof, which were due but not received during
the related Collection Period (and not previously covered by an unreimbursed
Servicer Advance); provided, however, that the Servicer shall not be obligated
to make any Servicer Advance pursuant to this Section 3.08 which the Servicer
determines in its sole discretion and in accordance with its customary servicing
practices would be a Nonrecoverable Advance. On each Determination Date, the
Servicer shall deliver to the Trustee the Servicer's Certificate listing the
aggregate amount of Scheduled Payments not received for the immediately prior
Collection Period as of the related Calculation Date which it has determined, in
its sole discretion and in accordance with its customary servicing practices, is
likely to be recoverable from the related Users and in respect of which the
Servicer shall so make Servicer Advances. The Servicer shall remit any Servicer
Advances to the Series 1998-1 Facility Account.

            SECTION 3.09 Substitutions and Modifications. In addition to any
right of substitution pursuant to Section 3.03 of the Contribution Agreement,
the Servicer has the right (but not the obligation) at any time to substitute
one or more Series 1998-1 Contracts (each a "Substitute Contract") for a Series
1998-1 Contract ("Predecessor Contract") if:

                        (i) the Predecessor Contract then meets the requirements
      for being a "Charged-Off Contract," and

                        (ii) the aggregate Contract Principal Balance(s) of such
      Substitute Contract or Contracts is at least equal to the aggregate
      Contract Principal Balance(s) of such Predecessor Contract or Contracts,
      each as of the Calculation Date immediately following the date of such
      substitution and calculated, with respect to the Predecessor Contract, as
      if such Predecessor Contract were not a Charged-Off Contract.

   36
                        (iii) the aggregate, cumulative Contract Principal
      Balance of all Substitute Contracts does not exceed 10% of the Original
      Aggregate Contract Principal Balance, exclusive of Substitute Contracts
      relating to any breach of the representations or warranties as provided in
      Section 3.01 of the Contribution Agreement.

            SECTION 3.10 Servicer to Act as Custodian. (a) The Servicer shall

            (b) The Servicer shall promptly report to the Trustee any failure by
      it to hold the complete Series 1998-1 Contracts as herein provided and
      shall promptly take appropriate action to remedy any such failure but only
      to the extent (i) any such failure is caused by the acts or omissions of
      the Servicer and (ii) such remedial action is otherwise within its
      capabilities or control. As custodian, the Servicer shall have and perform
      the following powers and duties:

                  (A) hold the Series 1998-1 Contracts on behalf of the Trustee
            for the benefit of the Series 1998-1 Noteholders, maintain accurate
            records pertaining to each Series 1998-1 Contract to enable it to

            maintaining a current inventory thereof;

                  (B) implement policies and procedures in accordance with the
            Servicer's normal business practices with respect to the handling
            and custody of the Series 1998-1 Contracts so that the integrity and
            physical possession of the Series 1998-1 Contracts will be
            maintained; and

                  (C) attend to all details in connection with maintaining
            custody of the Series 1998-1 Contracts on behalf of the Trustee on
            behalf of the Series 1998-1 Noteholders.

            (c) In acting as custodian of the Series 1998-1 Contracts, the
      Servicer agrees further that it does not and will not have or assert any
      beneficial ownership interest in such Series 1998-1 Contracts. The
      Servicer on behalf of the Series 1998-1 Noteholders shall mark
      conspicuously each original contractual document with a User, and its
      master data processing records evidencing each Series 1998-1 Contract with
      a legend, acceptable to the Trustee, evidencing that all right, title and
      interest in the Series 1998-1 Contracts has been granted to the Trustee as
      provided in this Series 1998-1 Supplement.

            (d) The Servicer agrees to maintain the Series 1998-1 Contracts at
      either its office in Voorhees, New Jersey or at such other location as
      shall from time to time be identified by prior written notice to the
      Trustee. Subject to the foregoing, the Servicer may temporarily move
      individual Series 1998-1 Contracts or any 


                                       33
   37
      portion thereof without notice as necessary to conduct collection and
      other servicing activities.

                                   ARTICLE IV.

                            SERIES EVENTS OF DEFAULT

            SECTION 4.01 Events of Default. Events of Default and Notice
Thereof.

            The following events constitute "Events of Default":

            (a) default by the Series Obligors in making Interest Payments when
      such payments become due and payable, or a default in reducing the
      Outstanding Principal Balance of any Class of Notes to zero by such
      Class's Stated Maturity Date (other than with respect to the Class D
      Notes);

            (b) default in the performance, or breach, by either Series Obligors
      of the provisions of its related organizational documents relating to
      corporate separateness;

            (c) default in the performance, or breach, of any covenant of either
      Series Obligors in the Master Agreement, or herein, and continuance of
      such default or breach for a period of 30 days after the earliest of (i)
      any officer of either Series Obligor first acquiring the knowledge
      thereof, (ii) the Trustee's giving written notice thereof to the Series
      Obligors or (iii) the holders of a majority of the then Outstanding Note
      Principal Balance giving written notice thereof to the Series Obligors and
      the Trustee;

            (d) if any representation or warranty of either Series Obligors made
      in the Master Agreement or any other writing provided to the holders of
      the Series 1998-1 Notes, excluding the representations and warranties made
      by the Series Obligors with respect to the Series 1998-1 Contracts, proves
      to be incorrect in any material respect as of the time when the same has
      been made; provided, however, that the breach of any representation or
      warranty made by either Series Obligors will be deemed to be "material"
      only if it negatively affects the Series 1998-1 Noteholders, the
      enforceability of the Master Agreement, this Series 1998-1 Supplement or
      of the Series 1998-1 Notes; or

            (e) insolvency or bankruptcy events relating to either Series
      Obligor.

            The Trustee shall give the Series 1998-1 Noteholders notice of all
uncured defaults known to it.

            If an Event of Default of the kind specified in clause (e) above
occurs, the unpaid principal amount of the Series 1998-1 Notes shall
automatically become due and payable together with all accrued and unpaid
interest thereon. If any other Event of Default occurs and is continuing, then
the Trustee will, if so directed by the holders of 


                                       34
   38
66-2/3% (33-1/3% in the case of a payment default pursuant to clause (a) above)
of the then Outstanding Note Principal Balance, or the holders of such
percentages of the then Outstanding Principal Balance of such Series 1998-1
Notes may declare the unpaid principal amount of all the Series 1998-1 Notes to
be due and payable immediately, together with all accrued and unpaid interest
thereon. The Trustee may, however, if the Event of Default involves other than
non-payment of principal or interest on the Series 1998-1 Notes, not sell the
Series 1998-1 Trust Estate unless such sale is for an amount greater than or
equal to the Outstanding Principal Balance of the Series 1998-1 Notes unless
directed to do so by the holders of 66-2/3% (33-1/3% in the case of a payment
default pursuant to clause (a) above) of the then Outstanding Note Principal
Balance.

            The Series Obligors shall furnish annually to the Trustee, a
statement of certain officers of the Series Obligors to the effect that to the
best of their knowledge the Series Obligors is not in default in the performance
and observance of the terms of the Master Agreement, this Series 1998-1
Supplement or the Series 1998-1 Notes or, if the Series Obligors are in default,
specifying such default.

            SECTION 4.02 Acceleration of Maturity; Rescission and Annulment.

            (a) If an Event of Default of the kind specified in Section 4.01(e)
      occurs, the unpaid principal amount of the Series 1998-1 Notes shall
      automatically become due and payable at par together with all accrued and
      unpaid interest thereon, without presentment, demand, protest or notice of
      any kind, all of which are hereby waived by the Series Obligors. If an
      Event of Default (other than an Event of Default of the kind described in
      Section 4.01(e)) occurs and is continuing, then and in every such case the
      Trustee shall, if so directed by the holders of Series 1998-1 Notes
      evidencing 66-2/3% of the then Outstanding Note Principal Balance may,
      declare the unpaid principal amount of all the Series 1998-1 Notes to be
      due and payable immediately, by a notice in writing to the Series Obligors
      (and to the Trustee if given by Series 1998-1 Noteholders), and upon any
      such declaration such principal amount shall become immediately due and
      payable together with all accrued and unpaid interest thereon, without
      presentment, demand, protest or other notice of any kind, all of which are
      hereby waived by the Series Obligors.

            (b) At any time after such a declaration of acceleration has been
      made and before a judgment or decree for payment of the money due has been
      obtained by the Trustee as hereinafter in this Article provided, the
      holders of Series 1998-1 Notes evidencing 66-2/3% of the then Outstanding
      Note Principal Balance, by written notice to the Obligors' Agent and the
      Trustee, may rescind and annul such declaration and its consequences if:

                        (i) the Series Obligors have paid or deposited with the
      Trustee a sum sufficient to pay:

                  (A) all principal on any Class A Notes, Class B Notes and
            Class C Notes which has become due otherwise than by such
            declaration of 


                                       35
   39
            acceleration and interest thereon from the date when the same first
            became due until the date of payment or deposit at the Class A-1
            Interest Rate, the Class A-2 Interest Rate, the Class A-3 Interest
            Rate, the Class B Interest Rate and the Class C Interest Rate, as
            applicable.

                  (B) all interest due with respect to any Class A Notes, Class
            B Notes and the Class C Notes and, to the extent that payment of
            such interest is lawful, interest upon overdue interest from the
            date when the same first became due until the date of payment or
            deposit at a rate per annum equal to the appropriate Note Interest
            Rates, and

                  (C) all sums paid or advanced by the Trustee hereunder and the
            reasonable compensation, expenses, disbursements, and advances of
            the Trustee, its agents and counsel;

            and

                       (ii) all Events of Default, other than the non-payment of
      the Outstanding Note Principal Balance which has become due solely by such
      declaration of acceleration, have been cured or waived as provided in
      Section 4.01.

No such rescission shall affect any subsequent Event of Default or impair any
right consequent thereon.

            SECTION 4.03 Remedies. (a) If an Event of Default occurs and is
continuing of which a Responsible Officer has actual knowledge, the Trustee
shall immediately give notice to each Series 1998-1 Noteholder and shall solicit
the Series 1998-1 Noteholders for advice. The Trustee shall then take such
action as so directed by the holders of Series 1998-1 Notes evidencing 66-2/3%
of the then Outstanding Note Principal Balance).

            (b) Following any acceleration of the Series 1998-1 Notes, the
      Trustee shall have all of the rights, powers and remedies with respect to
      the Series 1998-1 Trust Estate as are available to secured parties under
      the UCC or other applicable law. Such rights, powers and remedies may be
      exercised by the Trustee in its own name as trustee of an express trust.

            (c) If an Event of Default specified in Section 4.01(a) occurs and
      is continuing, the Trustee is authorized to recover judgment in its own
      name and as trustee of an express trust against the Series Obligors for
      the whole amount of principal and interest remaining unpaid.

            (d) In exercising its rights and obligations under this Section
      4.03, the Trustee may sell the Series 1998-1 Trust Estate in accordance
      with Section 4.16 hereof; provided, that if the Event of Default involves
      other than non-payment of principal or interest on the Series 1998-1
      Notes, then such sale must be for an amount greater than or equal to
      amounts due under clauses first through fourth in 


                                       36
   40
      Section 4.06. Neither the Trustee nor any Series 1998-1 Noteholder shall
      have any rights against the Series Obligors other than to enforce the Lien
      against the Series 1998-1 Contracts and the Equipment and to sell the
      Series 1998-1 Trust Estate.

            SECTION 4.04 Trustee Shall File Proofs of Claim. (a) In case of the
tendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition, or other judicial
proceeding relative to the Series Obligors, the Contributor, the Servicer or any
other obligor upon the Series 1998-1 Notes or the other obligations secured
hereby or relating to the property of the Series Obligors, the Contributor, the
Servicer or of such other obligor or their creditors, the Trustee (irrespective
of whether the principal of the Series 1998-1 Notes shall then be due and
payable as therein expressed or by declaration or otherwise and irrespective of
whether the Trustee shall have made any demand on the Series Obligors, the
Contributor or the Servicer for the payment of overdue principal or interest or
any such other obligation) shall by intervention in such proceeding or
otherwise,

                        (i) file and prove a claim for the whole amount of
      principal and interest owing and unpaid in respect of the Series 1998-1
      Notes and any other obligation secured hereby and to file such other
      papers or documents as may be necessary or advisable in order to have the
      claims of the Trustee (including any claim for the reasonable
      compensation, expenses, disbursements and advances of the Trustee, its
      agents and counsel) and of the Series 1998-1 Noteholders allowed in such
      judicial proceeding, and

                        (ii) collect and receive any moneys or other property
      payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator, or
other similar official in any such judicial proceeding is hereby authorized by
each Series 1998-1 Noteholder to make such payments to the Trustee and, in the
event that the Trustee shall consent to the making of such payments directly to
the Series 1998-1 Noteholders to pay to the Trustee any amount due it for the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel, and any other amounts due the Trustee.

            (b) Nothing herein contained shall be deemed to authorize the
      Trustee to authorize or consent to or accept or adopt on behalf of any
      Noteholder any plan of reorganization, arrangement, adjustment or
      composition affecting the Series 1998-1 Notes or the rights of any holder
      thereof or to authorize the Trustee to vote in respect of the claim of any
      Series 1998-1 Noteholder in any such proceeding.

            SECTION 4.05 Trustee May Enforce Claims Without Possession of Series
1998-1 Notes. All rights of action and claims under the Master Agreement, this
Series 1998-1 Supplement or the Series 1998-1 Notes may be prosecuted and
enforced by the Trustee without the possession of any of the Series 1998-1 Notes
or the production thereof in any proceeding relating thereto, and any such
proceeding instituted by the 


                                       37
   41
Trustee shall be brought in its own name as trustee of an express trust, and any
recovery of judgment shall, after provision for the payment of the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, be for the ratable benefit of the holders of the Series 1998-1
Notes in respect of which such judgment has been recovered.

            SECTION 4.06 Application of Money Collected. Any money collected by
the Trustee pursuant to this Article, and any moneys that may then be held or
thereafter received by the Trustee shall be applied in the following order, at
the date or dates fixed by the Trustee and, in case of the distribution of the
entire amount due on account of principal or interest, upon presentation of the
Series 1998-1 Notes and surrender thereof:

            first       to the payment of all costs and expenses of collection
      incurred by the Trustee and the Series 1997-1 Noteholders (including the
      reasonable fees and expenses of any counsel to the Trustee and the Series
      1998-1 Noteholders);

            second      if the person then acting as Servicer is not ABS or an

      discretion, except that no such allocation shall affect the allocation of
      such amounts or future payments received by any other Series 1998-1
      Noteholder;

            fourth      to the payment of amounts then due the Trustee
      hereunder;


                                       38
   42
            fifth       to the payment of the remainder, if any, to the Class D
      Noteholders, to the Series Obligors or any other Person legally entitled
      thereto.

            SECTION 4.07 Limitation on Suits. None of the Series 1998-1
Noteholders shall have any right to institute any proceeding, judicial or
otherwise, with respect to the Master Agreement, this Series 1998-1 Supplement
or the Series 1998-1 Notes, or for the appointment of a receiver or trustee, or
for any other remedy hereunder, unless:

                        (i) such Series 1998-1 Noteholder has previously given
      written notice to the Trustee of a continuing Event of Default;

                        (ii) the holders of not less than 66-2/3% of the then
      Outstanding Note Principal Balance of the Series 1998-1 Notes shall have
      made written request to the Trustee to institute proceedings in respect of
      such Event of Default in its own name as Trustee hereunder;

                        (iii) such Series 1998-1 Noteholder or Series 1998-1
      Noteholders have offered to the Trustee adequate indemnity against the
      costs, expenses and liabilities to be incurred in compliance with such
      request;

                        (iv) the Trustee for 30 days after its receipt of such
      notice, request and offer of indemnity failed to institute any such
      proceeding; and

                        (v) so long as any of the Series 1998-1 Notes remain
      Outstanding, no direction inconsistent with such written request has been
      given to the Trustee during such 30-day period by the holders of a 66-2/3%
      of the then Outstanding Note Principal Balance of the Series 1998-1 Notes;

it being understood and intended that no one or more Series 1998-1 Noteholders
shall have any right in any manner whatever by virtue of, or by availing of, any
provision of the Master Agreement, this Series 1998-1 Supplement or the Series
1998-1 Notes to affect, disturb, or prejudice the rights of any other Series
1998-1 Noteholders, or to obtain or to seek to obtain priority or preference
over any other Series 1998-1 Noteholders or to enforce any right under the
Master Agreement, this Series 1998-1 Supplement or the Series 1998-1 Notes,
except in the manner herein provided and for the equal and ratable benefit of
all the Series 1998-1 Noteholders. It is further understood and intended that so
long as any portion of the Series 1998-1 Notes remains Outstanding, ABS shall
not have any right to institute any proceeding, judicial or otherwise, with
respect to the Series 1998-1 Notes or for the appointment of a receiver or
trustee (including, without limitation, a proceeding under the Bankruptcy Code),
or for any other remedy hereunder. Nothing in this Section 4.07 shall be
construed as limiting the rights of otherwise qualified Series 1998-1
Noteholders to petition a court for the removal of a Trustee pursuant to Section
11.09 of the Master Agreement.

            SECTION 4.08 Unconditional Right of Series 1998-1 Noteholders to
Receive Principal and Interest. Notwithstanding any other provision in the
Master Agreement, this Series 1998-1 Supplement or the Series 1998-1 Notes other
than the 


                                       39
   43
provisions hereof limiting the right to recover amounts due on the Series 1998-1
Notes to recoveries from the property of the Series 1998-1 Trust Estate, the
holder of any Series 1998-1 Note shall have the absolute and unconditional right
to receive payment of the principal of and interest on such Note on the related
stated maturity date thereof, and to institute suit for the enforcement of any
such payment, and such rights shall not be impaired without the consent of such
Series 1998-1 Noteholder.

            SECTION 4.09 Restoration of Rights and Remedies. If the Trustee or
any Series 1998-1 Noteholder has instituted any proceeding to enforce any right
or remedy under the Master Agreement, this Series 1998-1 Supplement or the
Series 1998-1 Notes and such proceeding has been discontinued or abandoned for
any reason, or has been determined adversely to the Trustee or to such Series
1998-1 Noteholder, then and in every such case, subject to any determination in
such proceeding, the Series obligors, the Trustee and the Series 1998-1
Noteholders shall be restored severally and respectively to their former
positions hereunder and thereafter all rights and remedies of the Trustee and
the Series 1998-1 Noteholders continue as though no such proceeding had been
instituted.

            SECTION 4.10 Rights and Remedies Cumulative. Except as otherwise
provided with respect to the replacement or payment of mutilated, destroyed,
lost, or stolen Series 1998-1 Notes, no right or remedy herein conferred upon or
reserved to the Trustee or to the Series 1998-1 Noteholders is intended to be
exclusive of any other right or remedy, and every right and remedy shall, to the
extent permitted by law, be cumulative and in addition to every other right and
remedy given hereunder or now or hereafter existing at law or in equity or
otherwise. The assertion or employment of any right or remedy hereunder, or
otherwise, shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

            SECTION 4.11 Delay or Omission Not Waiver. No delay or omission of
the Trustee or of any holder of any Note to exercise any right or remedy
accruing upon any Event of Default shall impair any such right or remedy or
constitute a waiver of any such Event of Default or an acquiescence therein.
Every right and remedy given by this Article or by law to the Trustee or to the
Series 1998-1 Noteholders may be exercised from time to time, and as often as
may be deemed expedient, by the Trustee or by the Series 1997-1 Noteholders, as
the case may be.

            SECTION 4.12 Control by Series 1998-1 Noteholders. The Holders of
66-2/3% of the then Outstanding Note Principal Balance 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 Series 1998-1 Notes. Notwithstanding the foregoing:

                        (i) no such direction shall be in conflict with any rule
      of law or with the Master Agreement, this Series 1998-1 Supplement or the
      Series 1998-1 Notes;


                                       40
   44
                        (ii) the Trustee shall not be required to follow any
      such direction which the Trustee reasonably believes might result in any
      personal liability on the part of the Trustee for which the Trustee is not
      adequately indemnified; and

                        (iii) the Trustee may take any other action deemed
      proper by the Trustee which is not inconsistent with any such direction;
      provided that the Trustee shall give notice of any such action to each
      Noteholder.

            SECTION 4.13 Waiver of Events of Default. (a) The Holders of 66-2/3%
of the then Outstanding Note Principal Balance may, by one or more instruments
in writing, waive any Event of Default hereunder and its consequences, except a
continuing Event of Default:

                        (i) in respect of the payment of the principal of or
      premium or interest on any Series 1998-1 Note (which may only be waived by
      the holder of such Note), or

                        (ii) in respect of a covenant or provision hereof which
      cannot be modified or amended without the consent of the holder of each
      Outstanding Series 1998-1 Note affected (which only may be waived by the
      holders of all Outstanding Series 1998-1 Notes affected).

            (b) A copy of each waiver pursuant to Section 4.13(a) shall be
      furnished by the Obligors' Agent to the Trustee. Upon any such waiver,
      such Event of Default shall cease to exist and shall be deemed to have
      been cured, for every purpose of the Master Agreement, this Series 1998-1
      Supplement or the Series 1998-1 Notes; but no such waiver shall extend to
      any subsequent or other Event of Default or impair any right consequent
      thereon.

            SECTION 4.14 Undertaking for Costs. All parties hereto agree (and
each Holder of any Series 1998-1 Note by its acceptance thereof shall be deemed
to have agreed) that any court may in its discretion require, in any suit for
the enforcement of any right or remedy under the Master Agreement, this Series
1998-1 Supplement or the Series 1998-1 Notes, or in any suit against the Trustee
for any action taken, suffered or omitted by it as Trustee, the filing by any
party litigant in such suit of an undertaking to pay the costs of such suit, and
that such court may in its discretion assess reasonable costs, including
reasonable attorneys' fees, against any party litigant in such suit, having due
regard to the merits and good faith of the claims or defenses made by such party
litigant; but the provisions of this Section shall not apply to any suit
instituted by the Trustee, to any suit instituted by any Series 1998-1
Noteholder, or group of Series 1998-1 Noteholders, holding in the aggregate more
than 10% of the then Outstanding Principal Balance of the Series 1998-1 Notes,

            SECTION 4.15 Waiver of Stay or Extension Laws. The Series Obligors
covenant (to the extent that they may lawfully do so) that they will not at any
time insist upon, or plead, or in any manner whatsoever claim or take the
benefit or advantage of, any stay or extension law wherever enacted, now or at
any time hereafter in force, which may affect the covenants or the performance
of the Master Agreement, this Series 1998-1 Supplement or the Series 1998-1
Notes; and the Contributor (to the extent that it may lawfully do so) hereby
expressly waives all benefit or advantage of any such law and covenants that it
will not hinder, delay or impede the execution of any power herein granted to
the Trustee, but will suffer and permit the execution of every such power as
though no such law had been enacted.

            SECTION 4.16 Sale of Series 1998-1 Trust Estate. (a) The power to
effect any sale of any portion of the Series 1998-1 Trust Estate pursuant to
Section 4.03 shall not be exhausted by any one or more sales as to any portion
of the Series 1998-1 Trust Estate remaining unsold, but shall continue
unimpaired until the entire Series 1998-1 Trust Estate shall have been sold or
all amounts payable on the Series 1998-1 Notes shall have been paid. The Trustee
may from time to time, upon directions in accordance with Section 4.12, postpone
any public sale by public announcement made at the time and place of such sale.
For any public sale of the Series 1998-1 Trust Estate, the Trustee shall have
provided each Series 1998-1 Noteholder with notice of such sale at least two
weeks in advance of such sale which notice shall specify the date, time and
location of such sale.

            (b) To the extent permitted by applicable law, the Trustee shall not
      in any private sale sell to a third party the Series 1998-1 Trust Estate,
      or any portion thereof unless,

                        (i) the holders of 66-2/3% of the then Outstanding Note
      Principal Balance consent to or direct the Trustee in writing to make such
      sale; or

                        (ii) the proceeds of such sale would be not less than
      the sum of all amounts due to the Trustee hereunder and the entire
      Outstanding Note Principal Balance and interest due or to become due
      thereon on the Payment Date next succeeding the date of such sale.

The foregoing provisions shall not preclude or limit the ability of the Trustee
to purchase all or any portion of the Series 1998-1 Trust Estate at a private
sale.

            (c) In connection with a sale of all or any portion of the Series
      1998-1 Trust Estate:

                        (i) any one or more Series 1998-1 Noteholders may bid
      for and purchase the property offered for sale, and upon compliance with
      the terms of sale may hold, retain, and possess and dispose of such
      property, without further accountability, and any Series 1998-1 Noteholder
      may, in paying the purchase money therefore, deliver in lieu of cash any
      Outstanding Series 1998-1 Notes or claims for interest thereon for credit
      in the amount that shall, upon 


                                       42
   46
      distribution of the net proceeds of such sale, be payable thereon, and the
      Series 1998-1 Notes, in case the amounts so payable thereon shall be less
      than the amount due thereon, shall be returned to the Series 1998-1
      Noteholders after being appropriately stamped to show such partial
      payment;

                        (ii) the Trustee shall execute and deliver an
      appropriate instrument of conveyance transferring its interest in any
      portion of the Series 1998-1 Trust Estate in connection with a sale
      thereof;

                        (iii) the Trustee is hereby irrevocably appointed the
      agent and attorney-in-fact of the Contributor to transfer and convey its
      interest in any portion of the Series 1998-1 Trust Estate in connection
      with a sale thereof, and to take all action necessary to effect such sale;
      and

                        (iv) no purchaser or transferee at such a sale shall be
      bound to ascertain the Trustee's authority, inquire into the satisfaction
      of any conditions precedent or see to the application of any moneys.

            (d) The method, manner, time, place and terms of any sale of all or
      any portion of the Series 1998-1 Trust Estate shall be commercially
      reasonable.

            SECTION 5.01 Optional Redemption of Series 1998-1 Notes; Final
Disposition of Funds. (a) On any Payment Date following any Calculation Date as
of which the Aggregate Contract Principal Balance is less than ten percent
(10.00%) of the Original Aggregate Contract Principal Balance, the Series
Obligors shall have the option to cause the retirement of the Series 1998-1
Notes by depositing with the Trustee the sum of (i) the Class A Principal
Balance, the Class B Principal Balance and the Class C Principal Balance as of
such Payment Date (after giving effect to the payment of any principal on such
Payment Date), (ii) the Class A Note Interest, Class B Note Interest and Class C
Note Interest due on such Payment Date and (iii) the amount, if any, of all
Class A Overdue Principal, all Class B Overdue Principal and all Class C Overdue
Principal and all Class A Overdue Interest, all Class B Overdue Interest and all
Class C Overdue Interest. Upon receipt of such amounts and all amounts then owed
to the Trustee, the Trustee shall (x) make the final payment in full to the
Series 1998-1 Noteholders and (y) release any remaining Series 1998-1 Trust
Estate to the Series Obligors, as the holder of the Residual Interest.

            (b) Notice of any termination pursuant to this Section 5.01 shall be
given promptly by the Trustee, by letter to Noteholders mailed not earlier than
the 10th day and not later than the 30th day of the month immediately preceding
the month of such final Payment Date specifying (i) the Payment Date upon which
final payment of the Series 1998-1 Notes will be made, (ii) the scheduled amount
of any such final payment, (iii) that interest shall cease to accrue on the
Class A, Class B and Class C

   47
Series 1998-1 Notes on such final Payment Date and (iv) at the option of the
Trustee, the address for presentation of the Series 1998-1 Notes for final
payment. On such final Payment Date, the Trustee shall cause to be distributed
to the Series 1998-1 Noteholders an amount equal to the amount deposited by the
Series Obligors pursuant to Section 5.01(a) above. After such Payment Date,
interest on the Class A, Class B and Class C Notes shall cease to accrue. Each
Series 1998-1 Noteholder shall use reasonable efforts to present its Series
1998-1 Note to the Trustee at the office, if any, specified in the notice
described in clause (iv) of this paragraph (b), or in any similar written
notice, within sixty (60) days of such Series 1998-1 Noteholder's receipt of the
final payment of its Series 1998-1 Note. Each Noteholder shall indemnify the
Trustee for any damages suffered by the Trustee as a result of the Noteholder's
failure to present its Series 1998-1 Note on or after the final Payment Date
thereof.

            In the event that any amount due to any Series 1998-1 Noteholder
remains unclaimed, the Servicer shall, at its expense, cause to be published
once, in the eastern edition of The Wall Street Journal, notice that such money
remains unclaimed. If, within the period then specified in the escheat laws of
the State of New York after such publication, such amount remains unclaimed, the
Servicer shall be entitled to all unclaimed funds and other assets which remain
subject hereto, and the Trustee upon transfer of such funds shall be discharged
of any responsibility for such funds and, the Series 1998-1 Noteholders shall
look to the Servicer for payment.
