      Section 3.01. Initial Ownership. Upon the formation of the Trust by the
contribution by the Depositor pursuant to Section 2.05 and until the issuance of
the Trust Certificates, the Depositor shall be the sole beneficiary of the
Trust.

      Section 3.02. The Trust Certificates. The Trust Certificates shall be
substantially in the form of Exhibit B. The Trust Certificates shall be executed
by the Owner Trustee on behalf of the Trust by manual or facsimile signature of
an authorized officer of the Owner Trustee and attested on behalf of the Owner
Trustee by the manual or facsimile signature of an authorized officer of the
Owner Trustee and shall be deemed to have been validly issued when so executed.
Trust 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 Owner Trustee shall be valid and binding obligations of the Trust,
notwithstanding that such individuals or any of them have ceased to be so
authorized prior to the authentication and delivery of such Trust Certificates
or did not hold such offices at the date of such Trust Certificates. All Trust
Certificates shall be dated the date of their authentication.

      Section 3.03. Authentication and Delivery of Trust Certificates. The Owner
Trustee shall cause to be authenticated and delivered upon the order of the
Depositor, in exchange for the Contracts and the other assets of the Trust,
simultaneously with the sale, assignment and transfer to the Trust of the
Contracts, and the constructive delivery to the Owner Trustee of the Contract
Files and the other assets of the Trust, Trust Certificates duly authenticated
by the Owner Trustee, evidencing the entire ownership of the Trust and Notes

aggregate principal amount of, in the case of the (i) Class A-1 Notes, $       ,
(ii) Class A-2 Notes, $        , (iii) Class A-3 Notes, $        , (iv) Class
A-4 Notes, $        , (v) Class B Notes, $        , (vi) Class C Notes,
$         and (vii) Class D Notes, $        . No Trust Certificate shall be
entitled to any benefit under this Agreement, or be valid for any purpose,
unless there appears on such Trust Certificate a certificate of authentication
substantially in the form set forth in the form of Trust Certificate attached as
Exhibit B, executed by the Owner Trustee or its authenticating agent, by manual
signature, and such certificate upon any Trust Certificate shall be conclusive
evidence, and the only evidence, that such Trust Certificate has been duly
authenticated and delivered hereunder. The provisions of Sections 7.01, 7.03,
7.04 and 8.01 shall apply to any authenticating agent hereunder. Upon issuance,
authentication and delivery pursuant to the terms hereof, the Trust Certificates
will be entitled to the benefits of this Agreement.

      Section 3.04. Registration of Transfer and Exchange of Trust Certificates.

      (a) The Certificate Registrar shall keep or cause to be kept, a
Certificate Register, subject to such reasonable regulations as it may
prescribe. The Certificate Register shall provide for the registration of Trust
Certificates and transfers and exchanges of Trust Certificates as provided
herein. JP Morgan Chase Bank, 450 West 33rd Street, 15th Floor, New York, New
York 10001, Attention: Structured Finance Services (ABS) as agent for the Owner
Trustee, is hereby initially appointed Certificate Registrar for the purpose of
registering Trust Certificates


                                       10
<PAGE>

and transfers and exchanges of Trust Certificates as herein provided. In the
event that, subsequent to the Closing Date, the Owner Trustee notifies the
Master Servicer that JP Morgan Chase Bank is unable to act as Certificate
Registrar, the Master Servicer shall appoint another bank or trust company,
having an office or agency located in The City of New York, agreeing to act in
accordance with the provisions of this Agreement applicable to it, and otherwise
acceptable to the Owner Trustee, to act as successor Certificate Registrar
hereunder. The provisions of Sections 7.01, 7.03, 7.04 and 8.01 shall apply to
any Certificate Registrar hereunder.

      (b) Upon surrender for registration of transfer of any Trust Certificate
at the office of the Certificate Registrar, the Owner Trustee shall execute,
authenticate and deliver (or shall cause its authenticating agent to
authenticate and deliver), in the name of the designated transferee or
transferees, one or more new Trust Certificates of a like Certificate Percentage
Interest.

      (c) At the option of a Certificateholder, Trust Certificates may be
exchanged for other Trust Certificates of a like Certificate Percentage
Interest, upon surrender of the Trust Certificates to be exchanged at the office
of the Certificate Registrar. Whenever any Trust Certificates are so surrendered
for exchange, the Owner Trustee on behalf of the Trust shall execute,
authenticate and deliver (or shall cause its authenticating agent to
authenticate and deliver) the Trust Certificates that the Certificateholder
making the exchange is entitled to receive. Every Trust Certificate presented or
surrendered for registration of transfer or exchange shall be accompanied by a
written instrument of transfer in form satisfactory to the Owner Trustee and the
Certificate Registrar duly executed by the Holder thereof or his attorney duly
authorized in writing.

      (d) No service charge shall be made for any registration of transfer or
exchange of Trust Certificates, but the Owner Trustee 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 Trust Certificates.

      (e) The Trust Certificates may not be acquired by or for the account of a
Benefit Plan. By accepting and holding a Trust Certificate or a beneficial
interest therein, the Certificateholder thereof shall be deemed to have
represented and warranted that it is not a Benefit Plan nor will it hold such
Trust Certificate or a beneficial interest therein for the account of a Benefit
Plan.

      Any person who is not an affiliate of the Seller and acquires more than
49.9% of the Trust Certificates will be deemed to represent that it is not a
party in interest (within the meaning of ERISA) or a disqualified person (within
the meaning of Section 4975(e)(2) of the Code) with respect to any Benefit Plan,
other than a Benefit Plan that it sponsors for the benefit of its employees, and
that no plan with respect to which it is a party in interest has or will acquire
any interest in the Notes.

      (f) All Trust Certificates surrendered for registration of transfer or
exchange, if surrendered any agent of the Owner Trustee under this Agreement,
shall be delivered to the Owner Trustee and promptly cancelled by it, or, if
surrendered to the Owner Trustee, shall be promptly cancelled by it, and no
Trust Certificates shall be issued in lieu thereof except as


                                       11
<PAGE>

expressly permitted by any of the provisions of this Agreement. The Owner
Trustee shall dispose of cancelled Trust Certificates in accordance with the
normal industry practice.

      (g) As a condition to the registration of any transfer of a Trust
Certificate, the prospective transferee shall be required to represent in
writing to the Owner Trustee, the Seller and the Certificate Registrar the
following:

            (i) It has neither acquired nor will it transfer any Trust
      Certificate it purchases (or any interest therein) or cause any such Trust
      Certificates (or any interest therein) to be marketed on or through an
      "established securities market" within the meaning of Section 7704(b)(1)
      of the Code, including, without limitation, an over-the-counter-market or
      an interdealer quotation system that regularly disseminates firm buy or
      sell quotations.

            (ii) It either (A) is not, and will not become, a partnership,
      Subchapter S corporation or grantor trust for United States federal income
      tax purposes or (B) is such an entity, but none of the direct or indirect
      beneficial owners of any of the interests in such transferee have allowed
      or caused, or will allow or cause, 50% or more (or such other percentage
      as the transferor may establish prior to the time of such proposed
      transfer) of the value of such interests to be attributable to such
      transferee's ownership of Trust Certificates.

            (iii) It is not a Benefit Plan nor will it hold the Trust
      Certificates being transferred for the account of a Benefit Plan.

      The provisions of this Section generally are intended, among other things,
to prevent the Trust from being characterized as a "publicly traded partnership"
within the miining of Section 7704 of the Code, in reliance on Treasury
Regulations Sections 1.7704-1(e) and (h), and the Seller shall take such intent
into account in determining whether or not to consent to any proposed transfer
of any Trust Certificate.

      Section 3.05. Mutilated, Destroyed, Lost or Stolen Trust Certificates. If
(i) any mutilated Trust Certificate is surrendered to the Certificate Registrar,
or the Certificate Registrar receives evidence to its satisfaction of the
destruction, loss or theft of any Trust Certificate and (ii) there is delivered
to the Certificate Registrar and the Owner Trustee such security or indemnity as
may be required by them to save each of them harmless, then, in the absence of
notice that such Trust Certificate has been acquired by a protected purchaser,
the Owner Trustee on behalf of the Trust shall execute and the Owner Trustee or
its authenticating agent shall authenticate and deliver, in exchange for or in
lieu of any such mutilated, destroyed, lost or stolen Trust Certificate, a new
Trust Certificate of like tenor and Certificate Percentage Interest. In
connection with the issuance of any new Trust Certificate under this Section,
the Owner Trustee may require the payment by the Holder of a sum sufficient to
cover any tax or other governmental charge that may be imposed in relation
thereto. Any duplicate Trust Certificate issued pursuant to this Section shall
constitute complete and indefeasible evidence of ownership in the Trust, as if
originally issued, whether or not the lost, stolen or destroyed Trust
Certificate shall be found at any time.

      Section 3.06. Persons Deemed Owners. Prior to due presentation of a Trust
Certificate for registration of transfer, the Owner Trustee, the Certificate
Registrar, any Paying Agent and any of their respective agents may treat the
Person in whose name any Trust Certificate is registered as the owner of such
Trust Certificate for the purpose of receiving distributions pursuant to Section
5.02 and for all other purposes whatsoever, and none of the Owner Trustee, the
Certificate Registrar, any Paying Agent or any of their respective agents shall
be affected by any notice to the contrary.

      Section 3.07. Access to List of Certificateholders' Names and Addresses.
The Owner Trustee shall furnish or cause to be furnished to the Master Servicer
and the Depositor, within 15 days after receipt by the Certificate Registrar of
a written request therefor from the Master Servicer, the Certificateholders or
the Depositor, a list, in such form as the Master Servicer or the Depositor may
reasonably require, of the names and addresses of the Certificateholders as of
the most recent Record Date. If three or more Certificateholders, or one or more
Holders of Trust Certificates evidencing not less than 25% of the percentage
interests of the Trust Certificates (hereinafter referred to as "Applicants"),
apply in writing to the Owner Trustee, and such application states that the
Applicants desire to communicate with other Certificateholders with respect to
their rights hereunder or under the Trust Certificates and such application is
accompanied by a copy of the communication that such Applicants propose to
transmit, then the Owner Trustee shall, within five Business Days after the
receipt of such application, afford such Applicants access, during normal
business hours, to the current list of Certificateholders. Every
Certificateholder, by receiving and holding a Trust Certificate, agrees with the
Master Servicer, the Depositor and the Owner Trustee that none of the Master
Servicer, the Depositor or the Owner Trustee shall be held accountable by reason
of the disclosure of any such information as to the names and addresses of the
Certificateholders hereunder, regardless of the source from which such
information was derived.

      Section 3.08. Maintenance of Office or Agency. JP Morgan Chase Bank, as
agent for the Owner Trustee, shall maintain in the Borough of Manhattan, The
City of New York, an office or offices or agency or agencies where Trust
Certificates may be surrendered for registration of transfer or exchange and
where notices and demands to or upon the Owner Trustee in respect of the Trust
Certificates and the Basic Documents may be served. The Owner Trustee hereby
designates the office of JP Morgan Chase Bank at the address provided under the
definition of the term "Owner Trustee Corporate Trust Office" as its office for
such purposes. The Owner Trustee shall give prompt written notice to the
Depositor, the Master Servicer and to Certificateholders of any change in the
location of the Certificate Register or any such office or agency.

      Section 3.09. Appointment of Paying Agent. The Paying Agent shall make
distributions to Certificateholders from the Certificate Distribution Account
pursuant to Section 5.02(a) and shall report the amounts of such distributions
to the Owner Trustee. Any Paying Agent shall have the revocable power to
withdraw funds from the Certificate Distribution Account for the purpose of
making the distributions referred to above. The Owner Trustee may revoke such
power and remove the Paying Agent if the Owner Trustee determines in its sole
discretion that the Paying Agent shall have failed to perform its obligations
under this Agreement in any material respect. The Paying Agent initially shall
be Western Financial Bank and any co-paying agent chosen by the Paying Agent
that is acceptable to the Owner Trustee. Each Paying Agent


                                       13
<PAGE>

shall be permitted to resign as Paying Agent upon 30 days' written notice to the
Owner Trustee. In the event that Western Financial Bank shall no longer be the
Paying Agent, the Owner Trustee shall appoint a successor to act as Paying Agent
(which shall be a bank or trust company). The Owner Trustee shall cause such
successor Paying Agent or any additional Paying Agent appointed by the Owner
Trustee to execute and deliver to the Owner Trustee an instrument in which such
successor Paying Agent or additional Paying Agent shall agree with the Owner
Trustee that, as Paying Agent, such successor Paying Agent or additional Paying
Agent will hold all sums, if any, held by it for payment to the
Certificateholders in trust for the benefit of the Certificateholders entitled
thereto until such sums shall be paid to such Certificateholders. The Paying
Agent shall return all unclaimed funds to the Owner Trustee and upon removal of
a Paying Agent such Paying Agent shall also return all funds in its possession
to the Owner Trustee. The provisions of Sections 7.01, 7.03, 7.04 and 8.01 shall
apply to the Owner Trustee also in its role as Paying Agent, for so long as the
Owner Trustee shall act as Paying Agent and, to the extent applicable, to any
other paying agent appointed hereunder. Any reference in this Agreement to the
Paying Agent shall include any co-paying agent unless the context requires
otherwise. If the long term debt rating of the Paying Agent shall not be at
least Baa3 from Moody's and BBB- from Standard & Poor's, the Rating Agencies
shall be given notice of such lower long term debt rating.

      Section 3.10. Ownership by WFSRC4 of Trust Certificates. WFSRC4 shall on
the Closing Date retain Trust Certificates representing at least 100% of the
Certificate Percentage Interest and shall thereafter retain beneficial and
record ownership of Trust Certificates representing at least 1% of the
Certificate Percentage Interest (the "Retained Trust Certificate Percentage").
Any attempted transfer of any Trust Certificate that would reduce the interest
of WFSRC4 in the Trust below the Retained Trust Certificate Percentage shall be
void. The Owner Trustee shall cause any Trust Certificate issued to WFSRC4 on
the Closing Date (and any Trust Certificate issued in exchange therefor) to
contain a legend stating "THIS TRUST CERTIFICATE IS NON-TRANSFERABLE EXCEPT AS
PROVIDED IN SECTION 3.10 OF THE TRUST AGREEMENT".

Trustee for the benefit of the Certificateholders. If, at any time, the
Certificate Distribution Account ceases to be an Eligible Account, the Owner
Trustee (or the Depositor on behalf of the Owner Trustee, if the Certificate
Distribution Account is not then held by the Owner Trustee or an Affiliate
thereof) shall within ten Business Days (or such longer period, not to exceed 30
calendar days, as to which each Rating Agency) establish a new Certificate
Distribution Account as an Eligible Account and shall transfer any cash or any
investments to such new Certificate Distribution Account.

      Section 5.02. Application of Trust Funds.

      (a) On each Distribution Date, the Owner Trustee, at the direction of the
Master Servicer, will distribute to Certificateholders, in proportion to each
Certificateholder's Certificate Percentage Interest, amounts deposited into the
Certificate Distribution Account pursuant to Sections 5.06 and 9.01 of the Sale
and Servicing Agreement and Sections 2.07(c) and 5.06(a) of the Indenture with
respect to such Distribution Date.

      (b) On each Distribution Date, the Owner Trustee shall send to each
Certificateholder the statement or statements provided to the Owner Trustee by
the Master Servicer pursuant to Section 5.07 of the Sale and Servicing Agreement
with respect to such Distribution Date.

      (c) In the event that any withholding tax is imposed on the Trust's
payment (or allocations of income) to an Owner, such tax shall reduce the amount
otherwise distributable to the Owner in accordance with this Section. The Owner
Trustee is hereby authorized and directed to retain, or cause the Paying Agent
to retain, from amounts otherwise distributable to the Owners sufficient funds
for the payment of any tax that is legally owed by the Trust (but such
authorization shall not prevent the Owner Trustee from contesting any such tax
in appropriate proceedings, and withholding payment of such tax, if permitted by
law, pending the outcome of such proceedings). The amount of any withholding tax
imposed with respect to an Owner shall be treated as cash distributed to such
Owner at the time it is withheld by the Trust and remitted to the appropriate
taxing authority. If there is a possibility that withholding tax is payable with
respect to a distribution, the Owner Trustee may in its sole discretion withhold
such amounts in accordance with this subsection.

5.01 and 5.02, monies received by the Owner Trustee hereunder need not be
segregated in any manner except to the extent required by law or the Sale and
Servicing Agreement and may be deposited under such general conditions as may be
prescribed by law, and the Owner Trustee shall not be liable for any interest
thereon.

cause to be maintained) the books of the Trust on a calendar year basis and the

(including a partnership information return, United States Internal Revenue
Service Form 1065) and make such elections as from time to time may be required
or appropriate under any applicable state or federal statute or any rule or
regulation thereunder so as to maintain the Trust's characterization as a
partnership or a disregarded entity for federal income tax purposes, (iv) cause
such tax returns to be signed in the manner required by law and (v) collect or
cause to be collected any withholding tax as described in and in accordance with

                      AUTHORITY AND DUTIES OF OWNER TRUSTEE

      Section 6.01. General Authority. Subject to the provisions and limitations
of Sections 2.03 and 2.06, the Owner Trustee is authorized and directed to
execute and deliver the Basic Documents to which the Trust is to be a party and
each certificate or other document attached as an exhibit to or contemplated by
the Basic Documents to which the Trust is to be a party and any amendment,
certificate or other agreement, as evidenced conclusively by the Owner Trustee's
execution thereof. In addition to the foregoing, the Owner Trustee is
authorized, but shall not be obligated, to take all actions required of the
Trust pursuant to the Basic Documents. The Owner Trustee is further authorized
from time to time to take such action as the Administrator recommends with
respect to the Basic Documents.

      Section 6.02. General Duties. Subject to the provisions and limitations of
Sections 2.03 and 2.06, it shall be the duty of the Owner Trustee to discharge
(or cause to be discharged through the Administrator or such agents as shall be
appointed by it) all of its responsibilities pursuant to the terms of this
Agreement and the other Basic Documents to which the Trust is a party and to
administer the Trust in the interest of the Owners, subject to the Basic
Documents and in accordance with the provisions of this Agreement.
Notwithstanding the foregoing, the Owner Trustee shall be deemed to have
discharged its duties and responsibilities hereunder and under the other Basic
Documents to the extent the Administrator has agreed in the Administration
Agreement to perform any act or to discharge any duty of the Owner Trustee
hereunder or under any Basic Document, regardless of whether the Administration
Agreement is subsequently terminated or rejected by the Administrator, and the
Owner Trustee shall not be held liable for the default or failure of the
Administrator to carry out its obligations under the Administration Agreement.

      Section 6.03. Action Upon Instruction.

      (a) Subject to Article Four, in accordance with the terms of the Basic
Documents, the Owners may by written instruction direct the Owner Trustee in the
management of the Trust. Such direction may be exercised at any time by written
instruction of the Owners pursuant to Article Four.

      (b) The Owner Trustee shall not be required to take any action hereunder
or under any other Basic Document if the Owner Trustee shall have reasonably
determined, or shall have been advised by counsel, that such action is likely to
result in liability on the part of the Owner Trustee or is contrary to the terms
hereof or of any other Basic Document or is otherwise contrary to law.

      (c) Whenever the Owner Trustee is unable to decide between alternative
courses of action permitted or required by the terms of this Agreement or under
any other Basic Document, the Owner Trustee shall promptly give notice (in such
form as shall be appropriate under the circumstances) to the Owners requesting
instruction as to the course of action to be adopted, and to the extent the
Owner Trustee acts in good faith in accordance with any written instruction of
the Owners received, the Owner Trustee shall not be liable on account of such
action to any


                                       19
<PAGE>

Person. If the Owner Trustee shall not have received appropriate instruction
within ten days of such notice (or within such shorter period of time as
reasonably may be specified in such notice or may be necessary under the
circumstances) it may, but shall be under no duty to, take or refrain from
taking such action not inconsistent with this Agreement and the other Basic
Documents, as it shall deem to be in the best interests of the Owners, and shall
have no liability to any Person for such action or inaction.

      (d) In the event that the Owner Trustee is unsure as to the application of
any provision of this Agreement or any other Basic Document or any such
provision is ambiguous as to its application, or is, or appears to be, in
conflict with any other applicable provision, or in the event that this
Agreement permits any determination by the Owner Trustee or is silent or is
incomplete as to the course of action that the Owner Trustee is required to take
with respect to a particular set of facts, the Owner Trustee may give notice (in
such form as shall be appropriate under the circumstances) to the Owners
requesting instruction and, to the extent that the Owner Trustee acts or
refrains from acting in good faith in accordance with any such instruction
received, the Owner Trustee shall not be liable, on account of such action or
inaction, to any Person. If the Owner Trustee shall not have received
appropriate instruction within ten days of such notice (or within such shorter
period of time as reasonably may be specified in such notice or may be necessary
under the circumstances) it may, but shall be under no duty to, take or refrain
from taking such action not inconsistent with this Agreement or the other Basic
Documents, as it shall deem to be in the best interests of the Owners, and shall
have no liability to any Person for such action or inaction.

      Section 6.04. No Duties Except as Specified in this Agreement or in
Instructions. The Owner Trustee shall not have any duty or obligation to manage,
make any payment with respect to, register, record, sell, dispose of or
otherwise deal with the Trust Estate, or to otherwise take or refrain from
taking any action under, or in connection with, any document contemplated hereby
to which the Owner Trustee is a party, except as expressly provided by the terms
of this Agreement or in any document or written instruction received by the
Owner Trustee pursuant to Section 6.03 and no implied duties or obligations
shall be read into this Agreement or any other Basic Document against the Owner
Trustee. The Owner 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 or to prepare or file any Commission filing for the Trust or to
record this Agreement or any other Basic Document. The Owner Trustee
nevertheless agrees that it will, at its own cost and expense, promptly take all
action as may be necessary to discharge any liens (other than the lien of the
Indenture) on any part of the Trust Estate that result from actions by, or
claims against, the Owner Trustee that are not related to the ownership or the
administration of the Trust Estate.

      Section 6.05. No Action Except Under Specified Documents or Instructions.
The Owner Trustee shall not manage, control, use, sell, dispose of or otherwise
deal with any part of the Trust Estate except in accordance with (i) the powers
granted to and the authority conferred upon the Owner Trustee pursuant to this
Agreement, (ii) the other Basic Documents and (iii) any document or instruction
delivered to the Owner Trustee pursuant to Section 6.03.

      Section 6.06. Restrictions. The Owner Trustee shall not take any action
(i) that is inconsistent with the purposes of the Trust set forth in Section
2.03 or (ii) that, to the actual


                                       20
<PAGE>

knowledge of a Responsible Officer in the Owner Trustee Corporate Trust Office,
would result in the Trust's becoming taxable as a corporation for federal or
state income tax purposes. The Owners shall not direct the Owner Trustee to take
action that would violate the provisions of this Section.

             SUCCESSOR OWNER TRUSTEES AND ADDITIONAL OWNER TRUSTEES

      Section 10.01. Eligibility Requirements for Owner Trustee. The Owner
Trustee shall at all times be a corporation satisfying the provisions of Section
3807(a) of the Statutory Trust Act; authorized to exercise corporate trust
powers; having a combined capital and surplus of at least $         and
subject to supervision or examination by federal or state authorities; and
having (or having a parent that has) a rating of at least Baa3 by Moody's and
A-1 by Standard & Poor's. If such corporation shall publish reports of condition
at least annually pursuant to law or to the requirements of the aforesaid
supervising or examining authority, then for the purpose of this Section, 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. In case at any time the Owner Trustee shall cease to be eligible
in accordance with the provisions of this Section, the Owner Trustee shall
resign immediately in the manner and with the effect specified in Section 10.02.

      Section 10.02. Resignation or Removal of Owner Trustee. The Owner Trustee
may at any time resign and be discharged from the trusts hereby created by
giving written notice thereof to the Administrator. Upon receiving such notice
of resignation, the Administrator shall promptly appoint a successor Owner
Trustee by written instrument, in duplicate, one copy of which instrument shall
be delivered to the resigning Owner Trustee and one copy to the successor Owner
Trustee. If no successor Owner Trustee shall have been so appointed and have
accepted appointment within 30 days after the giving of such notice of
resignation, the resigning Owner Trustee may petition any court of competent
jurisdiction for the appointment of a successor Owner Trustee.

      If at any time the Owner Trustee shall cease to be eligible in accordance
with the provisions of Section 10.01 and shall fail to resign after written
request therefor by the Administrator, or if at any time the Owner Trustee shall
be legally unable to act, or shall be adjudged bankrupt or insolvent, or a
receiver of the Owner Trustee or of its property shall be appointed, or any
public officer shall take charge or control of the Owner Trustee or of its
property or affairs for the purpose of rehabilitation, conservation or
liquidation, then the Administrator may remove the Owner Trustee. If the
Administrator shall remove the Owner Trustee under the authority of the
immediately preceding sentence, the Administrator shall promptly appoint a
successor Owner Trustee by written instrument, in duplicate, one copy of which
instrument shall be delivered to the outgoing Owner Trustee so removed and one
copy to the successor Owner Trustee, and shall pay all fees owed to the outgoing
Owner Trustee.

      Any resignation or removal of the Owner Trustee and appointment of a
successor Owner Trustee pursuant to any of the provisions of this Section shall
not become effective until acceptance of appointment by the successor Owner
Trustee pursuant to Section 10.03 and payment of all fees and expenses owed to
the outgoing Owner Trustee. The Administrator shall provide notice of such
resignation or removal of the Owner Trustee to each Rating Agency.

      Section 10.03. Successor Owner Trustee. Any successor Owner Trustee
appointed pursuant to Section 10.02 shall execute, acknowledge and deliver to
the Administrator and to its


                                       29
<PAGE>

predecessor Owner Trustee an instrument accepting such appointment under this
Agreement, and thereupon the resignation or removal of the predecessor Owner
Trustee shall become effective, and such successor Owner Trustee, without any
further act, deed or conveyance, shall become fully vested with all the rights,
powers, duties and obligations of its predecessor under this Agreement, with
like effect as if originally named as Owner Trustee. The predecessor Owner
Trustee shall, upon payment of its fees and expenses, deliver to the successor
Owner Trustee all documents and statements and monies held by it under this
Agreement; and the Administrator and the predecessor Owner 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 Owner
Trustee all such rights, powers, duties and obligations.

      No successor Owner Trustee shall accept appointment as provided in this
Section unless at the time of such acceptance such successor Owner Trustee shall
be eligible pursuant to Section 10.01.

      Upon acceptance of appointment by a successor Owner Trustee pursuant to
this Section, the Administrator shall mail notice thereof to all
Certificateholders, the Indenture Trustee, the Noteholders and each Rating
Agency. If the Administrator shall fail to mail such notice within ten days
after acceptance of such appointment by the successor Owner Trustee, the
successor Owner Trustee shall cause such notice to be mailed at the expense of
the Administrator.

      Section 10.04. Merger or Consolidation of Owner Trustee. Any corporation
into which the Owner Trustee may be merged or converted or with which it may be
consolidated, or any corporation resulting from any merger, conversion or
consolidation to which the Owner Trustee shall be a party, or any corporation
succeeding to all or substantially all of the corporate trust business of the
Owner Trustee, shall be the successor of the Owner Trustee hereunder, without
the execution or filing of any instrument or any further act on the part of any
of the parties hereto, anything herein to the contrary notwithstanding;
provided, that such corporation shall be eligible pursuant to Section 10.01 and,
provided, further, that the Owner Trustee shall mail notice of such merger or
consolidation to each Rating Agency.

      Section 10.05. 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 Estate or any Financed Vehicle may at the time be located, the
Administrator and the Owner Trustee acting jointly shall have the power and
shall execute and deliver all instruments to appoint one or more Persons
approved by the Administrator and Owner Trustee to act as co-trustee, jointly
with the Owner Trustee, or as separate trustee or separate trustees, of all or
any part of the Trust Estate, and to vest in such Person, in such capacity, such
title to the Trust or any part thereof and, subject to the other provisions of
this Section, such powers, duties, obligations, rights and trusts as the
Administrator and the Owner Trustee may consider necessary or desirable. If the
Administrator shall not have joined in such appointment within 15 days after the
receipt by it of a request so to do, the Owner Trustee alone shall have the
power to make such appointment. No co-trustee or separate trustee under this
Agreement shall be required to meet the terms of eligibility as a successor
Owner Trustee pursuant to Section 10.01, except that such co-trustee or
successor trustee shall have (or have a parent that has) a rating of at least
Baa3 by Moody's and A-1 by Standard & Poor's, and


                                       30
<PAGE>

no notice of the appointment of any co-trustee or separate trustee shall be
required pursuant to Section 10.03.

      Each 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 Owner Trustee shall be conferred upon and exercised or performed
      by the Owner 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 Owner 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, the Owner 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 Estate 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 Owner Trustee;

            (ii) no trustee under this Agreement shall be personally liable by
      reason of any act or omission of any other trustee under this Agreement;
      and

            (iii) the Administrator and the Owner Trustee acting jointly may at
      any time accept the resignation of or remove any separate trustee or
      co-trustee.

      Any notice, request or other writing given to the Owner 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. 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 Owner Trustee or
separately, as may be provided 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 Owner
Trustee. Each such instrument shall be filed with the Owner Trustee and a copy
thereof given to the Administrator.

      Any separate trustee or co-trustee may at any time appoint the Owner
Trustee as 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 trustee or co-trustee
shall die, become incapable of acting, resign or be removed, all of its estates,
properties, rights, remedies and trusts shall vest in and be exercised by the
Owner Trustee, to the extent permitted by law, without the appointment of a new
or successor co-trustee or separate trustee.

without the consent of any of the Noteholders or the Certificateholders, to cure
any ambiguity, to correct or supplement any provisions in this Agreement or to
add any other provisions with respect to matters or questions arising under this

provided, however, that any such action shall not, as evidenced by an Opinion of
Counsel, adversely affect in any material respect the interests of any
Noteholder or Certificateholder.

      (b) This Agreement may also be amended from time to time by the Depositor
and the Owner Trustee, with the consent of the Holders of Trust Certificates
evidencing not less than a majority of the aggregate Certificate Percentage
Interest (which consent of any Holder of a Note or Trust Certificate given
pursuant to this Section or pursuant to any other provision of this Agreement
shall be conclusive and binding on such Holder and on all future Holders of such
Note or Trust Certificate, as the case may be, issued upon the transfer thereof
or in exchange thereof or in lieu thereof whether or not notation of such
consent is made thereon) and, if such amendment materially and adversely affects
the interests of the Noteholders, with the consent of Holders (as such term is
defined in the Indenture) of Notes evidencing not less than a majority of the
Outstanding Amount of the Notes for the purpose of adding any 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 Noteholders or the
Certificateholders; provided, however, that no such amendment shall increase or
reduce in any manner the amount of, or accelerate or delay the timing of, (i)
collections of payments on Contracts or distributions that shall be required to
be made for the benefit of the Noteholders or the Certificateholders or any
Interest Rate or (ii) reduce the aforesaid percentage of the Outstanding Amount
of the Notes and the Certificate Percentage Interest required to consent to any
such amendment, without the consent of the Holders of all outstanding Notes and
Trust Certificates.

      (c) Prior to the execution of any such amendment or consent, the Owner
Trustee shall furnish written notification of the substance of such amendment or
consent, together with a copy thereof, to the Indenture Trustee, the
Administrator and each Rating Agency.

Owner Trustee shall furnish written notification of the substance of such
amendment or consent to each Certificateholder. It shall not be necessary for
the consent of Certificateholders, Noteholders or the Indenture Trustee pursuant
to this Section 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 any other consents of
Certificateholders provided for in this Agreement or in any other Basic
Document) and of evidencing the authorization of the execution thereof by
Certificateholders shall be subject to such reasonable requirements as the Owner

subordination agreement for purposes of Section 510(a) of the Bankruptcy Code.

against it. No recourse shall be had for the payment of any amount owing
hereunder or for the payment of any fee hereunder or any other obligation of, or
claim against, the Seller arising out of or based upon Section 8.01 or 8.02, as
applicable, against any stockholder, employee, officer, agent, director or

The property of the Trust includes, among other things, a pool of retail
installment sale contracts (the "Contracts") for new and used automobiles and
light duty trucks (the "Financed Vehicles").

      Under the Trust Agreement, there will be distributed on the 20th of each
month or, if any such day is not a Business Day, the next succeeding Business
Day (each, a "Distribution Date"), commencing on         , 200  and ending no
later than         , 20   to the person in whose name this Trust Certificate
is registered at the close of business on the last calendar day immediately
preceding the related Distribution Date (the "Record Date"), such
Certificateholder's Certificate Percentage Interest in the amount to be
distributed to Certificateholders on such Distribution Date.

      The holder of this Trust Certificate acknowledges and agrees that its
rights to receive distributions in respect of this Trust Certificate are
subordinated to the rights of the Noteholders to the extent described in the
Sale and Servicing Agreement and the Indenture.

      It is the intent of the Seller, the Master Servicer and the
Certificateholders that, for purposes of federal income, state and local income
and single business tax and any other income taxes, the Trust will be
disregarded for tax purposes or treated as a partnership and the
Certificateholders (including the Depositor) will be taxable individually or as
partners in a partnership. The Depositor and the other Certificateholders, by
acceptance of a Trust Certificate, agree to treat, and to take no action
inconsistent with the treatment of, the Trust Certificates for such tax purposes
as partnership interests in the Trust.

      Each Certificateholder, by its acceptance of a Trust Certificate covenants
and agrees that such Certificateholder will not at any time institute against
the Trust, the Seller or the Depositor, or join in any institution against the
Trust, the Seller or the Depositor of, any bankruptcy, reorganization,
arrangement, insolvency or liquidation proceedings, or other proceedings under
any United States federal or state bankruptcy or similar law in connection with
any obligations relating to the Trust Certificates, the Notes, the Trust
Agreement or any of the other Basic Documents.

      Distributions on this Trust Certificate will be made as provided in the
Trust Agreement by the Owner Trustee by wire transfer or check mailed to the
Certificateholder of record in the Certificate Register without the presentation
or surrender of this Trust Certificate or the making of any notation hereon.
Except as otherwise provided in the Trust Agreement and notwithstanding the
above, the final distribution on this Trust Certificate will be made after due
notice by the Owner Trustee of the pendency of such distribution and only upon
presentation and surrender of this Trust Certificate at the office of the Paying
Agent or the office or agency maintained for that purpose by the Owner Trustee
in The City of New York.

      Reference is hereby made to the further provisions of this Trust
Certificate set forth on the reverse hereof, which further provisions shall for
all purposes have the same effect as if set forth at this place.

      Unless the certificate of authentication hereon shall have been executed
by an authorized officer of the Owner Trustee, by manual signature, this Trust
Certificate shall not entitle the


                                      B-2

holder hereof to any benefit under the Trust Agreement or any other Basic
Document or be valid for any purpose.

      THIS TRUST CERTIFICATE SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF
THE STATE OF DELAWARE, WITHOUT REFERENCE TO ITS CONFLICT OF LAW PROVISIONS, AND
THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE
DETERMINED IN ACCORDANCE WITH SUCH LAWS.

                            [REVERSE OF CERTIFICATE]

      The Trust Certificates do not represent an obligation of, or an interest
in, the Seller, the Depositor, the Master Servicer, the Owner Trustee or any of
their respective Affiliates and no recourse may be had against such parties or
their assets, except as expressly set forth or contemplated herein or in the
Trust Agreement or the other Basic Documents. In addition, this Trust
Certificate is not guaranteed by any governmental agency or instrumentality and
is limited in right of payment to certain collections and recoveries with
respect to the Contracts (and certain other amounts), in each case as more
specifically set forth herein and in the Sale and Servicing Agreement. Copies of
the Sale and Servicing Agreement and the Trust Agreement may be examined by any
Certificateholder upon written request during normal business hours at the
principal office of the Depositor and at such other places, if any, designated
by the Depositor.

      The Trust Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
parties thereto and the rights of the Certificateholders under the Trust
Agreement at any time by the parties thereto with the consent of Holders of
Trust Certificates evidencing not less than a majority of the aggregate
Certificate Percentage Interest and, if such amendment materially and adversely
affects the interests of the Noteholders, with the consent of Holders of Notes
evidencing not less than a majority of the Outstanding Amount of the Notes. Any
such consent by the Holder of this Trust Certificate shall be conclusive and
binding on such Holder and on all future Holders of this Trust Certificate and
of any Trust Certificate issued upon the transfer hereof or in exchange herefor
or in lieu hereof, whether or not notation of such consent is made upon this
Trust Certificate. The Trust Agreement also permits the amendment thereof, in
certain limited circumstances, without the consent of the Holders of any of the
Trust Certificates or the Notes.

      As provided in the Trust Agreement and subject to certain limitations
therein set forth, the transfer of this Trust Certificate is registerable in the
Certificate Register upon surrender of this Trust Certificate for registration
of transfer at the offices or agencies of the Certificate Registrar maintained
in The City of New York, accompanied by a written instrument of transfer in form
satisfactory to the Owner Trustee and the Certificate Registrar duly executed by
the Holder hereof or such Holder's attorney duly authorized in writing, and
thereupon one or more new Trust Certificates evidencing the same aggregate
interest in the Trust will be issued to the designated transferee. The initial
Certificate Registrar appointed under the Trust Agreement is JP Morgan Chase
Bank.

      As provided in the Trust Agreement and subject to certain limitations
therein set forth, Trust Certificates are exchangeable for new Trust
Certificates evidencing the same Certificate Percentage Interest, as requested
by the Holder surrendering the same. No service charge will be made for any such
registration of transfer or exchange, but the Owner Trustee or the Certificate
Registrar may require payment of a sum sufficient to cover any tax or
governmental charge payable in connection therewith.

      The Owner Trustee, the Certificate Registrar, the Paying Agent and any of
their respective agents may treat the Person in whose name this Trust
Certificate is registered as the owner hereof for all purposes, and none of the
Owner Trustee, the Certificate Registrar, the Paying Agent or any such agent
shall be affected by any notice to the contrary.

      The obligations and responsibilities created by the Trust Agreement and
the Trust created thereby shall terminate upon the payment to Certificateholders
of all amounts required to be paid to them pursuant to the Trust Agreement and
the Sale and Servicing Agreement and the disposition of all property held as
part of the Trust Estate.

      The Seller may at the Seller's option purchase the Trust Estate at a price
specified in the Sale and Servicing Agreement, and such purchase of the
Contracts and other property of the Trust will effect early retirement of the
Trust Certificates; however, such right of purchase is exercisable only as of
any Distribution Date as of which the sum of the Principal Balances of the
Contracts is less than or equal to $        .

      The Trust Certificates may not be acquired by a Benefit Plan. By accepting
and holding this Trust Certificate, the Holder hereof shall be deemed to have
represented and warranted that it is not a Benefit Plan and is not acquiring
this Trust Certificate or an interest therein for the account of a Benefit Plan.

      Any person who is not an affiliate of the Seller and acquires more than
49.9% of the Trust Certificates will be deemed to represent that it is not a
party in interest (within the meaning of ERISA) or a disqualified person (within
the meaning of Section 4975(e)(2) of the Code) with respect to any Benefit Plan,
other than a Benefit Plan that it sponsors for the benefit of its employees, and
that no plan with respect to which it is a party in interest has or will acquire
any interest in the Notes.
