        such other activities as may be required in connection with conservation
        of the Trust Estate and the making of distributions to the Owners and

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 hereto. 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

issued by the Owner Trustee and authenticated by the Indenture Trustee in
aggregate principal amount of, in the case of the (i) Class A-1 Notes, $______,
(ii) Class A-2 Notes, $______ and (iii) Class A-3 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 hereto as Exhibit C, 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. The Chase Manhattan 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 and transfers and exchanges of Trust
Certificates as herein provided. In the event that,


                                       10
<PAGE>   16

subsequent to the Closing Date, the Owner Trustee notifies the Master Servicer
that The Chase Manhattan 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 in authorized denominations of
like Certificate Percentage Interest.

        (c) At the option of a Certificateholder, Trust Certificates may be
exchanged for other Trust Certificates in authorized denominations of a like
aggregate principal amount, 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 Holder or any 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.

        (f) All Trust Certificates surrendered for registration of transfer or
exchange, if surrendered to the Company or any agent of the Owner Trustee or the
Company 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 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.

        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


                                       11
<PAGE>   17

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 fractional undivided
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,
the Insurer and the Depositor, within 15 days after receipt by the Certificate
Registrar of a written request therefor from the Master Servicer, the
Certificateholders, the Insurer 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. The Chase Manhattan 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 The Chase Manhattan 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


                                       12
<PAGE>   18

Certificateholders of any change in the location of the Certificate Register or
any such office or agency.

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

        Section 3.10. 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 The Chase Manhattan Bank and any co-paying agent chosen by the Paying Agent
that is acceptable to the Owner Trustee. Each Paying Agent shall be permitted to
resign as Paying Agent upon 30 days' written notice to the Owner Trustee. In the
event that The Chase Manhattan 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.

Company shall on the Closing Date retain Trust Certificates representing at
least __% of the Certificate Percentage Interest and shall thereafter retain
beneficial and record ownership of Trust Certificates representing at least __%
of the Certificate Percentage Interest (the "Retained Trust Certificate
Percentage"). Any attempted transfer of any Trust Certificate that would reduce
the interest of the Company in the Trust below the Retained Trust Certificate
Percentage shall be void. The Owner Trustee shall cause any Trust Certificate
issued to the Company 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 3.11 OF THE TRUST AGREEMENT".

        Section 5.01. Establishment of Trust Account. The Owner Trustee, for the
benefit of the Certificateholders, shall establish and maintain in the name of
the Trust an Eligible Account (the "Certificate Distribution Account"), bearing
a designation clearly indicating that the funds deposited therein are held for
the benefit of the Certificateholders. The Certificate Distribution Account
initially shall be established with The Chase Manhattan Bank in the state of New
York.

        The Owner Trustee shall possess all right, title and interest in funds
on deposit from time to time in the Certificate Distribution Account and in the
proceeds thereof. Except as otherwise expressly provided herein, the Certificate
Distribution Account shall be under the sole dominion and control of the Owner
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 the Insurer must consent) establish a new Certificate
Distribution Account as an Eligible Account and shall transfer any cash and/or
any investments to such new Certificate Distribution Account.

        Section 5.02. Application of Trust Funds.

        (a) On each Calculation Day and Distribution Date, the Owner Trustee
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 Section 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 paragraph (c).

the final payment upon retirement of each Trust Certificate, distributions
required to be made to each Certificateholder of record on the related Record
Date shall be made by check mailed to such Certificateholder at the address of
such Holder appearing in the Certificate Register or by wire transfer of
immediately available funds or pursuant to other arrangements.

        Section 5.04. No Segregation of Monies; No Interest. Subject to Sections
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.

        Section 5.05. Accounting and Reports to the Noteholders, Owners, the
Internal Revenue Service and Others. The Owner Trustee 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
Owners. The Owner Trustee shall elect under Section 1278 of the Code to include
in income currently any market discount that accrues with respect to the
Contracts. The Owner Trustee shall not make the election provided under Section
754 of the Code.

        Section 5.06. Signature on Returns; Tax Matters Partner.

                                   ARTICLE SIX

                      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 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 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. Without limiting the foregoing, the Owner Trustee shall on behalf of
the Trust file and prove any claim or claims that may exist against the Company
in connection with any claims paying procedure as part of an insolvency or
receivership proceeding involving the Company. 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 Insurer (so long as an Insurer Default shall not have occurred
and be continuing) or the Owners (if an Insurer Default shall have occurred and
be continuing) (the "Instructing Party") 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 Instructing Party 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,



                                       19
<PAGE>   25

the Owner Trustee shall promptly give notice (in such form as shall be
appropriate under the circumstances) to the Instructing Party 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 Instructing Party received, the Owner Trustee shall not be liable on account
of such action 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 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 Instructing
Party 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


                                       20
<PAGE>   26

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 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.

        shall require the Owner Trustee to expend or risk funds or otherwise
        incur any financial liability in the performance of any of its rights or
        powers hereunder or under any other Basic Document if the Owner Trustee
        shall have reasonable grounds for believing that repayment of such funds
        or adequate indemnity against such risk or liability is not reasonably
        assured or provided to it;

               (d) under no circumstances shall the Owner Trustee be liable for

        at the request, order or direction of the Instructing Party, unless such
        Instructing Party has offered to the Owner Trustee security or indemnity
        satisfactory to it against the costs, expenses and liabilities that may
        be incurred by the Owner Trustee therein or thereby; the right of the

        Agreement or in any other Basic Document shall not be construed as a
        duty, and the Owner Trustee shall not be answerable for other than its
        negligence or willful misconduct in the performance of any such act.

        Section 7.02. Furnishing of Documents. The Owner Trustee shall furnish
to the Owners promptly upon receipt of a written request therefor, duplicates or

        has all requisite corporate power and authority to execute, deliver and
        perform its obligations under this Agreement.

               (b) It has taken all corporate action necessary to authorize the

               (c) Neither the execution nor the delivery by it of this
        Agreement, nor the consummation by it of the transactions contemplated
        hereby nor compliance by it with any of the terms or provisions hereof
        will contravene any federal or Delaware law, governmental rule or
        regulation governing the banking or trust powers of the Owner Trustee or
        any judgment or order binding on it, or constitute any default under its
        charter documents or bylaws or any indenture, mortgage, contract,
        agreement or instrument to which it is a party or by which any of its
        properties may be bound or result in the creation or imposition of any
        lien, charge or encumbrance on the Trust Estate resulting from actions
        by or claims against the Owner Trustee individually which are unrelated
        to this Agreement or the other Basic Documents.

<PAGE>   29

directors or other governing body of any corporate party as conclusive evidence
that such resolution has been duly adopted by such body and that the same is in
full force and effect. As to any fact or matter the method of determination of
which is not specifically prescribed herein, the Owner Trustee may for all
purposes hereof rely on a certificate, signed by the president or any vice
president or by the treasurer or other authorized officers of the relevant
party, as to such fact or matter and such certificate shall constitute full
protection to the Owner Trustee for any action taken or omitted to be taken by
it in good faith in reliance thereon.

performance of its duties and obligations under this Agreement or the other

Trustee shall not be liable for the conduct or misconduct of such agents or
attorneys if such agents or attorneys shall have been selected by the Owner
Trustee with reasonable care, and (ii) may consult with counsel, accountants and
other skilled persons to be selected with reasonable care and employed by it.

good faith by it in accordance with the written opinion or advice of any such
counsel, accountants or other such persons and not contrary to this Agreement or
any other Basic Document.

        Section 7.05. Not Acting in Individual Capacity. Except as otherwise
provided in this Article Seven, in accepting the trusts hereby created, Chase

by reason of the transactions contemplated by this Agreement or any other Basic
Document shall look only to the Trust Estate for payment or satisfaction
thereof.

        Section 7.06. Owner Trustee Not Liable for Trust Certificates, Notes or

the Trust Certificates) shall be taken as the statements of the Depositor, and
the Owner Trustee assumes no responsibility for the correctness thereof. The
Owner Trustee makes no representations as to the validity or sufficiency of this
Agreement, any other Basic Document or the Trust Certificates (other than the
signature of the Owner Trustee and the certificate of authentication on the
Trust Certificates and the representations and warranties in Section 7.03) or
the Notes, or of any Contract or related documents. The Owner Trustee shall at
no time have any responsibility or liability for or with respect to the
legality, validity and enforceability of any Contract, or the perfection and
priority of any security interest created by any Contract in any Financed
Vehicle or the 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

representation; or any action of the Administrator, the Indenture Trustee or the
Master Servicer or any subservicer taken in the name of the Owner Trustee.

        Section 7.07. Owner Trustee May Own Trust Certificates and Notes. The
Owner Trustee in its individual or any other capacity may become the owner or
pledgee of Trust Certificates or Notes and may deal with the Depositor, the

and suits, and any and all reasonable costs, expenses and disbursements
(including reasonable legal fees and expenses) of any kind and nature whatsoever

termination of the Owner Trustee or the termination of this Agreement. In the
event of any claim, action or proceeding for which indemnity will be sought
pursuant to this Section, the Owner Trustee's choice of legal counsel shall be
subject to the approval of the Depositor, which approval shall not be

        (a) The Trust shall dissolve upon the final distribution by the Owner
Trustee 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. The bankruptcy, liquidation, dissolution, death or incapacity of

Registrar (if other than the Owner Trustee) and the Paying Agent at the time
such notice is given to Certificateholders. Upon presentation and surrender of

upon the final payment of the Trust Certificates.

        (d) In the event that all of the Certificateholders shall not surrender
their Trust Certificates for cancellation within six months after the date
specified in the above-mentioned written notice, the Owner Trustee shall give a
second written notice to the remaining Certificateholders to surrender their
Trust Certificates for cancellation and receive the final distribution with
respect thereto. If within one year after the second notice all the Trust
Certificates shall not have been surrendered for cancellation, the Owner Trustee
may take appropriate steps, or may appoint an agent to take appropriate steps,
to contact the remaining Certificateholders concerning surrender of their Trust
Certificates, and the cost thereof shall be paid out of the funds and other
assets that shall remain subject to this Agreement. Any funds remaining in the
Trust after exhaustion of such remedies at least 18 months after the date of
dissolution shall be distributed by the Owner Trustee to a charity designated by
the Master Servicer.

             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 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 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 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, with the consent of the
Insurer (so long as an Insurer Default shall not have occurred and be
continuing) 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.


                                       29

        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
Certificateholders, the Insurer, 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



                                       30

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 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:

               (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 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 extent permitted by law, without the appointment of a new
or successor co-trustee or separate trustee.

        Section 11.01. Supplements and Amendments.

        (a) This Agreement may be amended by the Depositor, the Company and the
Owner Trustee, with the prior written consent of the Insurer (so long as an
Insurer Default shall not have occurred and be continuing), 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 Agreement
that shall not be inconsistent with the provisions of this Agreement; provided,

adversely affect in any material respect the interests of any Noteholder or
Certificateholder.

        (b) This Agreement may also be amended from time to time with the prior
written consent of the Insurer (so long as an Insurer Default shall not have

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 51% 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

consent, together with a copy thereof, to the Indenture Trustee, the Insurer,
the Administrator and each Rating Agency.

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

delivery thereof by the Issuer or the Owner Trustee, as the case may be, have

supplemented from time to time, the "Trust Agreement"), among WFS Financial Auto
Loans, Inc. (the "Depositor"), WFS Investments, Inc. (the "Company"), Financial

Trust Agreement, to which Trust Agreement the Holder of this Trust Certificate
by virtue of its acceptance hereof assents and by which such Holder is bound.
The property of the Trust includes, among other things, (i) a pool of retail
installment sale contracts (the "Contracts") for new and used automobiles and
light duty trucks (the "Financed Vehicles") and (ii) the Certificate Policy.

        Under the Trust Agreement, there will be distributed on each January 20,

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, the Company 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 treated as
a partnership and the Certificateholders (including the Company) will be treated
as partners in that partnership. The Company 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 or Certificate Owner, as the
case may be, will not at any time institute against the Trust, the Seller, the
Depositor or the Company, or join in any institution against the Trust, the
Seller, the Depositor or the Company 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 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 Company, 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 51% 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 51% 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 The Chase Manhattan
Bank.

        As provided in the Trust Agreement and subject to certain limitations
therein set forth, Trust Certificates are exchangeable for new Trust
Certificates of authorized denominations 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


                                      B-4
<PAGE>   47


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 its 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 Aggregate Scheduled Balance is less
than or equal to 10% of the Cut-Off Date Aggregate Scheduled Balance.

        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.
