        Section 2.06 Declaration of Trust. The Owner Trustee hereby declares
that it will hold the Trust Estate in trust upon and subject to the conditions
set forth herein for the sole purpose of conserving the Trust Estate and
collecting and disbursing the periodic income therefrom for the use and benefit
of the Owners, subject to the obligations of the Trust under the Basic
Documents. It is the intention of the parties hereto that the Trust constitute a
business trust under the Business Trust Statute and that this Agreement
constitute the governing instrument of such business trust. It is the intention
of the parties hereto that, solely for income and franchise tax purposes, on and
after the Closing Date (i) so long as there is a sole Residual Interestholder,
the Trust shall be disregarded as an entity separate from the sole Residual
Interestholder, and (ii) if there is more than one Residual Interestholder, the
Trust shall be treated as a partnership, with the assets of the partnership
being the Contracts and other assets held by the Trust, and with the partners of
the partnership being the Owners of the Residual Interest Instruments, and the
Notes being debt of the partnership. The Trust shall not elect to be treated as
an association under Treasury Regulation Section 301.7701-3(a) for federal
income tax purposes. The parties agree that, unless otherwise required by
appropriate tax authorities, the Trust will file or cause to be filed annual or
other necessary returns, reports and other forms consistent with the
characterization of the Trust as provided in the second preceding sentence.
Effective as of the date hereof, the Owner Trustee shall have all rights, powers
and duties set forth herein and in the Business Trust Statute for the


                                      -5-
<PAGE>   10
sole purpose and to the extent necessary to accomplish the purposes of the Trust
as set forth in Section 2.03.

        Section 2.07 Title to Trust Property. Subject to the Indenture, legal
title to all the Trust Estate shall be vested at all times in the Trust as a
separate legal entity except where applicable law in any jurisdiction requires
title to any part of the Trust Estate to be vested in a trustee or trustees, in
which case title shall be deemed to be vested in the Owner Trustee and/or a
separate trustee, as the case may be.

        The Owners shall not have legal title to any part of the Trust Estate.
The Owners shall be entitled to receive distributions with respect to their
undivided ownership interest therein only in accordance with Articles Five and
Nine. No transfer, by operation of law or otherwise, of any right, title or
interest of the Owners to and in their ownership interest in the Trust Estate
shall operate to terminate this Agreement or the trusts hereunder or entitle any
transferee to an accounting or to the transfer to it of legal title to any part
of the Trust Estate.

        Section 2.08 Situs of Trust. The Trust will be located and administered
in the State of Delaware or the State of New York. All bank accounts maintained
on behalf of the Trust shall be located in the State of California, the State of
Delaware or the State of New York. The Trust shall not have any employees in any
state other than Delaware; provided, however, that nothing herein shall restrict
or prohibit the Owner Trustee from having employees within or without the State
of Delaware. Payments will be received by the Trust only in California, Delaware
or New York and payments will be made by the Trust only from California,
Delaware or New York. The only office of the Trust will be at the Owner Trustee
Corporate Trust Office.

        Section 2.09 Representations and Warranties of the Depositor.

        (a) The Depositor hereby represents and warrants to the Owner Trustee

        properties.

               (v) There are no proceedings or investigations pending, or to the

            RESIDUAL INTEREST INSTRUMENTS AND TRANSFER OF INTERESTS

        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 Residual Interest Instruments, the Depositor shall be the sole beneficiary
of the Trust.

        Section 3.02 The Residual Interest Instruments and the Notes.

        (a) The Residual Interest Instruments shall not be issued with a
principal amount. The Residual Interest Instruments 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 authenticated by the Trust Agent by
the manual or facsimile signature of an authorized officer of the Trust Agent
and shall be deemed to have been validly issued when so executed and
authenticated. Residual Interest Instruments 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 or the Trust Agent
shall be validly issued by the Trust, notwithstanding that such individuals or
any of them have ceased to be so authorized prior to the execution,
authentication and delivery of such Residual Interest Instruments or did not
hold such offices at the date of such Residual Interest Instruments. All
Residual Interest Instruments shall be dated the date of their authentication.

        (b) The Notes 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 shall be authenticated as provided in the Indenture. Notes bearing
the manual or facsimile signature of an individual who was, at the time when
such signature was affixed, authorized to sign on behalf of the Owner Trustee
shall be deemed to have been validly executed by the Trust, notwithstanding
that such individual has ceased to be so authorized prior to the execution and
delivery of such Notes or did not hold such office at the date of such Notes.

        Section 3.03 Execution, Authentication and Delivery of Residual Interest
Instruments and Notes. The Owner Trustee shall cause to be executed,
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 such other assets,
(a) the Residual Interest Instruments representing 100% of the Percentage
Interests of the Residual Interest, evidencing the entire ownership of the
Trust, and (b) Notes executed by the Trust in aggregate principal amount of, in
the case of the (i) Class A-1 Notes, $77,800,000, (ii) Class A-2 Notes,
$120,000,000, (iii) Class A-3 Notes, $131,000,000, (iv) Class A-4 Notes,
$94,200,000, and (v) Class B Notes, $27,000,000. The Trust Agent is hereby
authorized to direct, on behalf of the Trust, the Indenture Trustee to
authenticate and deliver the Notes upon the order of the Depositor. No Residual
Interest Instrument shall entitle its Owner to any benefit under this Agreement,
or be valid for any purpose, unless there appears on such Residual Interest
Instrument a certificate of authentication substantially in the form set forth
in the form of Residual Interest Instrument attached hereto as Exhibit B,
executed by the Trust Agent or another authenticating agent of the Owner
Trustee, by manual or facsimile signature, and such certificate upon any
Residual Interest Instrument shall be conclusive evidence, and the only
evidence, that


                                      -8-
<PAGE>   13
such Residual Interest Instrument has been duly authenticated and delivered
hereunder. Upon issuance, authorization and delivery pursuant to the terms
hereof, the Residual Interest Instruments will be entitled to the benefits of
this Agreement.

        Section 3.04 Registration of Transfer and Exchange of Residual Interest
Instruments.

        (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
Residual Interest Instruments and transfers and exchanges of Residual Interest
Instruments as provided herein. The Trust Agent, as agent for the Trust, is
hereby initially appointed Certificate Registrar for the purpose of registering
Residual Interest Instruments and transfers and exchanges of Residual Interest
Instruments as herein provided. In the event that, subsequent to the Closing
Date, the Trust Agent notifies the Administrator that the Trust Agent is unable
to act as Certificate Registrar, the Administrator 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 Depositor, to act as successor
Certificate Registrar hereunder.

        (b) Upon surrender for registration of transfer of any Residual Interest
Instrument at the office of the Certificate Registrar, the Owner Trustee shall
execute, authenticate and deliver (or shall cause the Trust Agent, as its
authenticating agent, to authenticate and deliver), in the name of the
designated transferee or transferees, one or more new Residual Interest
Instruments in authorized denominations of a like aggregate principal amount.

        (c) At the option of a Owner of a Residual Interest Instrument, Residual
Interest Instruments may be exchanged for other Residual Interest Instruments in
authorized denominations of a like Percentage Interest, upon surrender of the
Residual Interest Instruments to be exchanged at the office of the Certificate
Registrar. Whenever any Residual Interest Instruments are so surrendered for
exchange, the Owner Trustee on behalf of the Trust shall execute, authenticate
and deliver (or shall cause the Trust Agent, as its authenticating agent, to
authenticate and deliver) the Residual Interest Instruments that the Owner
making the exchange is entitled to receive. Every Residual Interest Instrument
presented or surrendered for registration of transfer or exchange shall be
accompanied by a written instrument of transfer in form satisfactory to the
Trust Agent and the Certificate Registrar duly executed by the Owner thereof or
his attorney duly authorized in writing. In addition, each Residual Interest
Instrument presented or surrendered for registration of transfer and exchange
must be accompanied by a letter from the prospective Owner certifying as to the
representations set forth in Section 3.11(a) and (b).

        (d) No service charge shall be made for any registration of transfer or
exchange of Residual Interest Instruments, but the Owner Trustee or, on its
behalf, the Trust Agent, 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 Residual Interest Instruments.

        (e) All Residual Interest Instruments surrendered for registration of
transfer or exchange, if surrendered to any agent of the Owner Trustee under
this Agreement, shall be delivered to the Trust Agent and promptly canceled by
it, or, if surrendered to the Trust Agent, shall be promptly canceled by it, and
no Residual Interest Instruments shall be issued in lieu


                                      -9-
<PAGE>   14
thereof except as expressly permitted by any of the provisions of this
Agreement. The Trust Agent shall dispose of canceled Residual Interest
Instruments in accordance with the normal industry practice.

        Section 3.05 Mutilated, Destroyed, Lost or Stolen Residual Interest
Instruments. If (a) any mutilated Residual Interest Instrument is surrendered to
the Certificate Registrar, or the Certificate Registrar receives evidence to its
satisfaction of the destruction, loss or theft of any Residual Interest
Instrument, and (b) there is delivered to the Certificate Registrar and the
Trust Agent such security or indemnity as may be required by them to save each
of them harmless, then, in the absence of notice that such Residual Interest
Instrument has been acquired by a bona fide purchaser, the Owner Trustee on
behalf of the Trust shall execute and the Trust Agent, as its authenticating
agent, shall authenticate and deliver, in exchange for or in lieu of any such
mutilated, destroyed, lost or stolen Residual Interest Instrument, a new
Residual Interest Instrument of like tenor and fractional undivided interest. In
connection with the issuance of any new Residual Interest Instrument under this
Section, the Owner Trustee or, on its behalf, the Trust Agent, may require the
payment by the Owner of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto. Any duplicate Residual Interest
Instrument 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 Residual Interest Instrument shall
be found at any time.

        Section 3.06 Persons Deemed Owners. Prior to due presentation of a
Residual Interest Instrument for registration of transfer, the Owner Trustee,
the Trust Agent, the Certificate Registrar, any Paying Agent and any of their
respective agents may treat the Person in whose name any Residual Interest
Instrument is registered as the owner of such Residual Interest Instrument for
the purpose of receiving distributions pursuant to Section 5.01 and for all
other purposes whatsoever, and none of the Owner Trustee, the Trust Agent, 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 Owners' Names and Addresses. The Trust
Agent shall furnish or cause to be furnished to the Servicer, the Insurer and
the Depositor, within 15 days after receipt by the Trust Agent of a written
request therefor from the Servicer, the Insurer or the Depositor, a list, in
such form as the Servicer, the Insurer or the Depositor may reasonably require,
of the names and addresses of the Owners as of the most recent Record Date. Each
Owner, by receiving and holding a Residual Interest Instrument, agrees with the
Servicer, the Depositor, the Owner Trustee and the Trust Agent that none of the
Servicer, the Depositor, the Owner Trustee or the Trust Agent shall be held
accountable by reason of the disclosure of any such information as to its name
and address hereunder, regardless of the source from which such information was
derived.

        Section 3.08 Maintenance of Office or Agency. The Trust Agent shall
maintain in the City of New York an office or offices or agency or agencies
where Residual Interest Instruments may be surrendered for registration of
transfer or exchange and where notices and demands to or upon the Trust Agent in
respect of the Residual Interest Instruments and the Basic Documents may be
served. The Trust Agent hereby designates the office of The Chase Manhattan Bank
at the address provided under the definition of the term "TRUST AGENT OFFICE" as
its office for such purposes. The Trust Agent shall give prompt written notice
to the Owner Trustee, the Depositor,


                                      -10-
<PAGE>   15
the Servicer and to the Owners of any change in the location of the Certificate
Register or any such office or agency.

        Section 3.09 Temporary Residual Interest Instruments. Pending the
preparation of definitive Residual Interest Instruments, the Owner Trustee, on
behalf of the Trust, may execute, authenticate and deliver, temporary Residual
Interest Instruments that are printed, lithographed, typewritten, mimeographed
or otherwise produced, in any authorized denomination, substantially of the
tenor of the definitive Residual Interest Instruments in lieu of which they are
issued. If temporary Residual Interest Instruments are issued, the Depositor
will cause definitive Residual Interest Instruments to be prepared without
unreasonable delay. After the preparation of definitive Residual Interest
Instruments, the temporary Residual Interest Instruments shall be exchangeable
for definitive Residual Interest Instruments upon surrender of the temporary
Residual Interest Instruments at the office or agency to be maintained as
provided in Section 3.08, without charge to the Owner. Upon surrender for
cancellation of any one or more temporary Residual Interest Instruments, the
Owner Trustee shall execute, authenticate and deliver (or shall cause the Trust
Agent, as its authenticating agent, to authenticate and deliver) in exchange
therefor a like principal amount of definitive Residual Interest Instruments in
authorized denominations. Until so exchanged, the temporary Residual Interest
Instruments shall in all respects be entitled to the same benefits hereunder as
definitive Residual Interest Instruments.

        Section 3.10 Appointment of Paying Agent. The Owner Trustee, on behalf
of the Trust, hereby appoints the Trust Agent as Paying Agent under this
Agreement. The Paying Agent shall make distributions to Owners pursuant to
Section 5.01 hereof and shall report the amounts of such distributions to the
Owner Trustee. The Paying Agent shall have the revocable power to withdraw funds
from the Payment Account for the purpose of making the distributions referred to
above. The Owner Trustee on behalf of the Trust may revoke such power and remove
the Paying Agent if the Owner Trustee is directed in writing to do so by the
Administrator. Each Paying Agent shall be permitted to resign as Paying Agent
upon 30 days' written notice to the Trust. In the event that the Trust Agent
shall no longer be the Paying Agent, the Administrator shall appoint a successor
to act as Paying Agent (which shall be a bank or trust company acceptable to the
Insurer). The Administrator shall cause such successor Paying Agent or any
additional Paying Agent appointed by the Administrator to execute and deliver to
the Trust an instrument in which such successor Paying Agent or additional
Paying Agent shall agree with the Trust 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 Owners in trust for the benefit of the Owners entitled
thereto until such sums shall be paid to the Owners. The Paying Agent shall
return all unclaimed funds to the Trust and upon removal of a Paying Agent such
Paying Agent shall also return all funds in its possession to the Trust. The
provisions of Sections 7.01, 7.03, 7.04 and 8.01 shall apply to the Trust Agent
also in its role as Paying Agent, for so long as the Trust Agent 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. Notwithstanding anything
herein to the contrary, the Trust Agent and the Paying Agent shall be the same
entity as the Indenture Trustee under the Indenture and the Sale and Servicing
Agreement, unless an Insurer Default has occurred and is continuing. In such
event, the Trust Agent and the Paying Agent shall resign and the Owner Trustee
shall assume the duties and obligations of the Trust Agent and the Paying Agent
hereunder and under the Sale and Servicing Agreement.

               NO TRANSFER OF THIS RESIDUAL INTEREST INSTRUMENT OR ANY
               BENEFICIAL INTEREST THEREIN SHALL BE MADE TO ANY PERSON UNLESS

                   APPLICATION OF TRUST FUNDS; CERTAIN DUTIES

        Section 5.01 Application of Trust Funds.

        (a) On each Distribution Date, the Trust Agent, on behalf of the Owner
Trustee, shall direct the Paying Agent to distribute to the Owners from amounts
on deposit in the Payment Account the distributions as provided in Section
4.04(b) of the Sale and Servicing Agreement with respect to such Distribution
Date.

        (b) On each Distribution Date, the Trust Agent, on behalf of the Owner
Trustee, shall cause the Paying Agent to send to each Owner the statement or
statements provided to the Owner Trustee or the Trust Agent by the Servicer
pursuant to Section 4.05 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 Trust
Agent is hereby authorized and directed 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 or the Trust Agent 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 Trust Agent shall withhold such amounts in
accordance with this paragraph (c).

transfer of immediately available funds or pursuant to other arrangements), the
amount to be distributed to such Owner pursuant to such Owner's Residual
Interest Instruments.

        Section 5.03 No Segregation of Monies; No Interest. Subject to Section
5.01, monies received by the Trust Agent 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 Trust Agent shall not be liable for any interest thereon.

        Section 5.04 Accounting and Reports to the Noteholders, Owners, the
Internal Revenue Service and Others. The Trust Agent shall (a) maintain (or
cause to be maintained) the books of the Trust on a calendar year basis and the
accrual method of accounting, (b) deliver to each Owner, as may be required by
the Code and applicable Treasury Regulations, such information as may be
required (including Schedule K-1) to enable each Owner to prepare its federal
and state income tax returns, (c) file such tax returns relating to the Trust
(including a partnership information return, IRS 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 for federal income tax
purposes, (d) cause such tax returns to be signed in the manner required by law
and (e) collect or cause to be collected any withholding tax as described in and
in accordance with Section 5.01(c) with respect to income or distributions to

Depositor holds a Residual Interest Instrument, and otherwise the holder of the
largest Percentage Interest in the Residual Interest Instruments shall sign such
documents.

        (b) The Depositor shall be designated the "tax matters partner" of the
Trust pursuant to Section 6231(a)(7)(A) of the Code and applicable Treasury
Regulations, as long as the Depositor holds a Residual Interest Instrument, and
otherwise the owner of the largest Percentage Interest in the Residual Interest

              AUTHORITY AND DUTIES OF OWNER TRUSTEE AND TRUST AGENT

        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 on behalf of the Trust 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 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:

        (a) 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
with the consent of the Insurer) 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 or the Trust Agent has agreed in the
Administration Agreement or this Agreement, respectively, to perform any act or
to discharge any duty of the Owner Trustee or the Trust hereunder or under any
Basic Document, and the Owner Trustee shall not be held liable for the default
or failure of the Administrator or the Trust Agent to carry out its obligations
under the Administration Agreement or this Agreement, respectively; and

        (b) it shall be the duty of the Trust Agent to discharge all of its
responsibilities pursuant to the terms of this Agreement and the other Basic
Documents to which the Trust and the Trust Agent are 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.

        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 or the
Trust Agent 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) Neither the Owner Trustee nor the Trust Agent shall be required to
take any action hereunder or under any other Basic Document if the Owner Trustee
or the Trust Agent, as applicable, 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 the Trust Agent, as


                                      -17-
<PAGE>   22
applicable, or is contrary to the terms hereof or of any other Basic Document or
is otherwise contrary to law.

        (c) Whenever the Owner Trustee or the Trust Agent 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 or the Trust
Agent, as applicable, shall promptly give notice (in such form as shall be
appropriate under the circumstances) to the Owners and the Insurer requesting
instruction as to the course of action to be adopted, and to the extent the
Owner Trustee or the Trust Agent, as applicable, acts in good faith in
accordance with any written instruction from the Owners received, the Owner
Trustee or the Trust Agent, as applicable, shall not be liable on account of
such action to any Person. If the Owner Trustee or the Trust Agent 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 or the Trust Agent 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 the Trust
Agent 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 or the Trust Agent 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 or the Trust Agent, as applicable, acts or refrains from
acting in good faith in accordance with any such instruction received, the Owner
Trustee or the Trust Agent, as applicable, shall not be liable, on account of
such action or inaction, to any Person. If the Owner Trustee or the Trust Agent
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. Neither the Owner Trustee nor the Trust Agent shall 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 or the Trust Agent, as
applicable, 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 or the Trust Agent, as applicable, 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 or the Trust Agent. Neither the Owner
Trustee nor the Trust Agent shall have any 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 with the Commission any filing for
the Trust or to record this Agreement or any other Basic Document. Each of the
Owner


                                      -18-
<PAGE>   23
Trustee and the Trust Agent nevertheless agrees that it will, at its own cost
and expense, promptly take all action as may be necessary to discharge any liens
on any part of the Trust Estate that result from actions by, or claims against,
the Owner Trustee or the Trust Agent, as applicable, that are not related to the
ownership or the administration of the Trust Estate or the Grant of any portion
thereof to the Indenture Trustee pursuant to the Indenture.

        Section 6.05 No Action Except Under Specified Documents or Instructions.
Neither the Owner Trustee nor the Trust Agent shall 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 or the Trust Agent, as applicable, pursuant to this Agreement,
(ii) the other Basic Documents and (iii) any document or instruction delivered
to the Owner Trustee or the Trust Agent, as applicable, pursuant to Section
6.03.

        Section 6.06 Restrictions. Neither the Owner Trustee nor the Trust Agent
shall 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 knowledge of the Owner
Trustee or the Trust Agent, as applicable, 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 or the Trust Agent to take action that would
violate the provisions of this Section.

have offered to the Owner Trustee or the Trust Agent, as applicable, security or
indemnity satisfactory to it against the costs, expenses and liabilities that
may be incurred by the Owner Trustee or the Trust Agent, as applicable, therein
or thereby; the right of the Owner Trustee and the Trust Agent to perform any
discretionary act enumerated in this Agreement or in any other Basic Document
shall not be construed as a duty, and neither the Owner Trustee nor the Trust
Agent shall be answerable for other than its negligence or willful misconduct in
the performance of any such act;

any investigation into the facts or matters stated in any resolution,
certificate, statement, instrument, opinion, report, notice, request, consent,
order, approval, bond or other paper or document, unless requested in writing to
do so by the Administrator or Owners; provided, however, that if the payment
within a reasonable time to the Owner Trustee or Trust Agent, as applicable, of
the costs, expenses or liabilities likely to be incurred by it in the making of
such investigation is, in the opinion of the Owner Trustee or Trust Agent, as
applicable, not reasonably assured to it by the security afforded to them by the

require reasonable indemnity against such cost, expense or liability as a
condition to taking any such action;

to anyone in acting upon any signature, instrument, notice, resolution, request,
consent, order, certificate, report, opinion, bond or other document or paper

the Trust Agent, as applicable, for any action taken or omitted to be taken by

attorneys shall have been selected by the Owner Trustee or the Trust Agent with
reasonable care, and (ii) may consult with counsel, accountants and other
skilled persons to be selected with reasonable care and employed by it at the
sole expense of the Depositor. Neither the Owner Trustee nor the Trust Agent
shall be liable for anything done, suffered or omitted in good faith by it in

or other such persons and not contrary to this Agreement or any other Basic
Document.

Interest Instruments, Notes or Contracts. The recitals contained herein and in
the Residual Interest Instruments (other than the respective signatures of the

certificate of authentication on the Residual Interest Instruments) shall be
taken as the statements of the Depositor, and neither the Owner Trustee nor the
Trust Agent assumes responsibility for the correctness thereof. Neither the
Owner Trustee nor the Trust Agent makes any representations as to the validity
or sufficiency of this Agreement, any other Basic Document or the Residual
Interest Instruments (other than the respective signatures of the Owner Trustee
and the Trust Agent, and, in the case of the Trust Agent, the certificate of
authentication on the Residual Interest Instruments) or the Notes, or of any

maintenance of any such perfection and priority, or for or with respect to the
sufficiency of the Trust Estate or its ability to generate the payments to be
distributed to Owners under this Agreement or the Noteholders under the
Indenture, including, without limitation, the existence, condition and ownership
of any Financed Vehicle; the existence and enforceability of any insurance
thereon; the existence and contents of any Contract on any computer or other
record thereof; the validity of the assignment of any Contract to the Trust or
of any intervening assignment; the completeness of any Contract; the performance
or enforcement of any Contract; the compliance by the Depositor, the Insurer or
the Servicer with any warranty or representation made under any Basic Document
or in any related document or the accuracy of any such warranty or
representation; or any action of the Administrator, the Indenture Trustee or the
Servicer or any subservicer taken in the name of the Owner Trustee or the Trust
Agent.

Instruments and Notes. The Owner Trustee and the Trust Agent, each in its
individual or any other capacity, may become the owner or pledgee of Residual

                         TERMINATION OF TRUST AGREEMENT

        Section 9.01 Termination of Trust Agreement.

        (a) This Agreement (other than Article Eight) and the Trust shall
terminate and be of no further force or effect upon the earlier of (i) final
distribution of all monies or other property or proceeds of the Trust Estate in
accordance with the terms of the Indenture, the Sale and Servicing Agreement and
Article Five and (ii) the expiration of 21 years from the death of the survivor
of the descendants of Joseph P. Kennedy, the late Ambassador of the United
States to the Court of St. James's, living on the date hereof. The bankruptcy,
liquidation, dissolution, death or incapacity of any Owner shall not (i) operate
to terminate this Agreement or the Trust, (ii) entitle such Owner's legal
representatives or heirs to claim an accounting or to take any action or
proceeding in any court for a partition or winding up of all or any part of the
Trust or Trust Estate or (iii) otherwise affect the rights, obligations and
liabilities of the parties hereto.

        (b) Except as provided in Section 9.01(a), neither the Depositor, the
Insurer nor any Owner shall be entitled to revoke or terminate the Trust.

        (c) Notice of any termination of the Trust, specifying the Distribution
Date upon which Owners shall surrender their Residual Interest Instruments to
the Paying Agent for payment of the final distribution and cancellation, shall
be given by the Trust Agent by letter to Owners mailed within five Business Days
of receipt of notice of such termination from the Servicer given pursuant to
Section 8.01(b) of the Sale and Servicing Agreement, stating (i) the
Distribution Date upon or with respect to which final distribution in respect of
the Residual Interest Instruments shall be made upon presentation and surrender
of the Residual Interest Instruments at the office of the Paying Agent in the
City of New York therein designated, (ii) the amount of any such final payment
and (iii) that the Record Date otherwise applicable to such Distribution Date is
not applicable, payments being made only upon presentation and surrender of the
Residual Interest Instruments at the office of the Paying Agent therein
specified. The Trust Agent shall give such notice to the Certificate Registrar
(if other than the Trust Agent) and the Paying Agent (if other than the Trust
Agent) at the time such notice is given to Owners. Upon presentation and
surrender of the Residual Interest Instruments, the Paying Agent shall cause to
be distributed to Owners on a pro rata basis any amounts remaining in the Trust
upon the termination of this Agreement. In addition, the Trust Agent shall
notify the Rating Agencies upon the final distribution in respect of the
Residual Interest Instruments.

        (d) In the event that all of the Owners shall not surrender their
Residual Interest Instruments for cancellation within six months after the date
specified in the above-mentioned written notice, the Trust Agent shall give a
second written notice to the remaining Owners to surrender their Residual
Interest Instruments for cancellation and receive the final distribution with
respect thereto. If within one year after the second notice all the Owners shall
not have been surrendered for cancellation, the Trust Agent may take appropriate
steps, or may appoint an agent to take appropriate steps, to contact the
remaining Owners concerning surrender of their Residual Interest Instruments,
and the cost thereof shall be paid out of the funds and other assets that shall
remain subject to this Agreement.

       SUCCESSOR OWNER TRUSTEES, ADDITIONAL OWNER TRUSTEE AND TRUST AGENT

        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 Business Trust Statute; authorized to exercise corporate trust
powers; having a combined capital and surplus of at least $50,000,000 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 and the Insurer. 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; provided that the Depositor and the Insurer shall have
received written confirmation from each Rating Agency that the proposed
appointment will not result in an increased capital charge to the Insurer by
either Rating Agency. 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 or the Insurer 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 the Insurer, 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, or if at any time the Owner Trustee shall have
breached any representation or warranty contained in Section 7.03(a)(iii)
(without regard to any knowledge qualification), then the Administrator or the
Insurer may remove the Owner Trustee. If the Owner Trustee shall be removed
under the authority of the immediately preceding sentence, the Administrator
shall promptly appoint a successor Owner Trustee acceptable to the Insurer by
written instrument, in duplicate, one copy of which


                                      -26-
<PAGE>   31
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, the Insurer and to its 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 Owners, the
Insurer, the Depositor, the Servicer, 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


                                      -27-
<PAGE>   32
the Administrator, the Insurer 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 to do so, the Owner Trustee and the Insurer 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, provided that such co-trustee or successor trustee must
be acceptable to the Rating Agencies and no notice of the appointment of any
co-trustee or separate trustee shall be required pursuant to Section 10.03.

        Section 10.06 Appointment of Trust Agent. Each separate trustee and
co-trustee shall, to the extent permitted by law, be appointed and act subject
to the following provisions and conditions:

        (a) 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;

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

        (c) the Administrator, the Insurer 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 and the Insurer.

        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


                                      -28-
<PAGE>   33
extent permitted by law, without the appointment of a new or successor
co-trustee or separate trustee.

        The Owner Trustee on behalf of the Trust hereby appoints The Chase
Manhattan Bank as Trust Agent for the purpose of making the distributions from
the Payment Account to the persons entitled thereto pursuant to Section 4.03 of
the Sale and Servicing Agreement and for purposes of performing the other duties
specified to be performed by the Trust Agent under this Agreement and the other
Basic Documents. The Owner Trustee and the Trust Agent each agree that upon the
occurrence and continuation of an Insurer Default, the Trust Agent shall resign
and the Owner Trustee shall assume all rights, duties and obligations of the
Trust Agent under the Sale and Servicing Agreement and this Agreement, including
without limitation, the obligations of the Trust Agent pursuant to Sections
3.02, 3.03, 3.04, 3.05, 3.07, 3.08, 3.09, 3.10 and 5.01 hereof. The Trust Agent,
in its capacity as Trust Agent, shall not have any rights, duties or obligations
except as expressly provided in this Agreement and the Sale and Servicing
Agreement.

questions arising hereunder that shall not be inconsistent with the provisions
of this Agreement; provided, however, that (i) any such action shall not
materially and adversely affect the interests of any Noteholder or Owner; (ii)
any such action shall be deemed not to materially and adversely affect the

letter from each Rating Agency to the effect that the amendment would not result
in a downgrading or withdrawal of the ratings then assigned to the Notes by such
Rating Agency or (B) an opinion of counsel to such effect; and (iii) any such
action shall be deemed not to materially and adversely affect the interest of
any Owner if the Person requesting such amendment obtains an opinion of counsel

pursuant to any other provision of this Agreement shall be conclusive and
binding on such Holder and on all future Holders of such Note 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 Owners, with the consent of Owners

Trustee shall furnish written notification of the substance of such amendment or
consent, together with a copy thereof, to the Indenture Trustee, the Insurer,
the Administrator and each Rating Agency.

        (d) Promptly after the execution of any such amendment or consent, the
Trust Agent shall furnish written notification of the substance of such
amendment or consent to each Owner. It shall not be necessary for the consent of
Owners, Noteholders or the Indenture Trustee pursuant to this Section to approve

Trust Agent may, but shall not be obligated to, enter into any such amendment
that affects the Owner Trustee's or the Trust Agent's own rights, duties or
immunities under this Agreement or otherwise.
