                                       4
<PAGE>   10

Noteholder, as the case may be, of record as of the Record Date immediately
preceding the date on which such action is to be taken, or consent given, by the
Noteholders or the Certificateholder. Solely for the purposes of any action to
be taken, or consented to, by the Noteholders, any Note registered in the name
of the Seller or any Affiliate thereof shall be deemed not to be outstanding;
provided, however, that, solely for the purpose of determining whether the Owner
Trustee, the Indenture Trustee or the Trust Collateral Agent is entitled to rely
upon any such action or consent, only Notes which the Owner Trustee, the
Indenture Trustee or the Trust Collateral Agent, respectively, has been notified
to be so owned shall be so disregarded.

         SECTION 1.4. Material Adverse Effect. Whenever a determination is to be
made under this Agreement as to whether a given event, action, course of conduct
or set of facts or circumstances could or would have a material adverse effect
on the Noteholders or the Certificateholder (or any similar or analogous
determination), such determination shall be made without taking into account the
funds available from claims under the Class A Note Policy.

the Indenture Trustee on behalf of the Noteholders, and to hold, manage and
distribute to the Certificateholder and the Depositor pursuant to the terms of
the Sale and Servicing Agreement any portion of the Owner Trust Estate released
from the Lien of, and remitted to the Trust, pursuant to the Indenture; (iv) to
enter into and perform its obligations under the Basic Documents to which it is
a party; (v) to engage in those activities, including entering into agreements,
that are necessary, suitable or convenient to accomplish the foregoing or are

<PAGE>   11

         The Trust is hereby authorized to engage in the foregoing activities.
The Trust shall not engage in any activity other than in connection with the
foregoing or other than as required or authorized by the terms of this Agreement
or the Basic Documents.

         SECTION 2.4. Appointment of Owner Trustee. The Depositor hereby
appoints the Owner Trustee as trustee of the Trust effective as of the date
hereof, to have all the rights, powers and duties set forth herein.

         SECTION 2.5. Initial Capital Contribution of Trust Estate. The
Depositor hereby sells, assigns, transfers, conveys and sets over to the Owner
Trustee, as of the date hereof, the sum of $1. The Owner Trustee hereby
acknowledges receipt in trust from the Depositor, as of the date hereof, of the
foregoing contribution, which shall constitute the initial Owner Trust Estate
and shall be deposited in the Distribution Account. The Depositor shall pay
organizational expenses of the Trust as they may arise.

         SECTION 2.6. Declaration of Trust. The Owner Trustee hereby declares
that it will hold the Owner Trust Estate in trust upon and subject to the
conditions set forth herein for the use and benefit of the Certificateholder,
subject to the obligations of the Trust under the Basic Documents. It is the
intention and agreement 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
and agreement of the parties hereto that, solely for income and franchise tax
purposes, the Trust shall be treated as a security device only, or
alternatively, if such characterization is not respected for any applicable
income or franchise tax purposes, the Trust shall be treated solely for such
income or franchise tax purposes as a non-entity disregarded as an entity
separate from its owner under Treasury Regulations Section 301.7701-3(b)(ii);
provided, however, that if any Class of Notes is treated as an equity interest
in the Trust for any applicable income or franchise tax purposes, it is the
intention and agreement of the parties hereto that, solely for such income or
franchise tax purposes, the Trust shall then be treated as a partnership and
that, unless otherwise required by appropriate tax authorities, only after such
time the Servicer, on behalf of 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 a partnership for such income or franchise tax
purposes. None of the parties hereto shall make the election provided in
Treasury Regulations Section 301.7701-3(c) to have the Trust classified as an
association taxable as a corporation. Effective as of the date hereof, the Owner
Trustee shall have all rights, powers and duties set forth herein and to the
extent not inconsistent herewith, in the Business Trust Statute with respect to
accomplishing the purposes of the Trust. The Owner Trustee shall file the
Certificate of Trust with the Secretary of State.

         SECTION 2.7. Liability. (a) The Depositor shall pay organizational
expenses of the Trust as they may arise or shall, upon the request of the Owner
Trustee, promptly reimburse the Owner Trustee for any such expenses paid by the
Owner Trustee.

                           (b) The Holder, other than to the extent set forth in
         clause (a), shall not have any personal liability for any liability or
         obligation of the Trust.

                                       6
<PAGE>   12

         SECTION 2.8. Title to Trust Property. (a) Legal title to all the Owner
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 Owner Trust Estate to be vested in a trustee or trustees, in which
case title shall be deemed to be vested in the Owner Trustee, a co-trustee
and/or a separate trustee, as the case may be.

                           (b) The Holder shall not have legal title to any part
         of the Trust Property. The Holder shall be entitled to receive
         distributions with respect to its undivided ownership interest therein
         only in accordance with Article IX and Section 5.7 of the Sale and
         Servicing Agreement. No transfer, by operation of law or otherwise, of
         any right, title or interest by the Certificateholder of its ownership
         interest in the Owner 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 Property.

         SECTION 2.9. Situs of Trust. The Trust will be located and administered
in the State of Delaware. All bank accounts maintained by the Owner Trustee on
behalf of the Trust shall be located in the State of Delaware or the State of
New York. Payments will be received by the Trust only in Delaware or New York
and payments will be made by the Trust only from Delaware or 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, the
Servicer or any agent of the Trust from having employees within or without the
State of Delaware. The only office of the Trust will be at the Corporate Trust
Office in Delaware.

         SECTION 2.10. Representations and Warranties of the Depositor. The
Depositor makes the following representations and warranties on which the Owner
Trustee relies in accepting the Owner Trust Estate in trust and issuing the
Certificates, and upon which the Insurer relies in issuing the Class A Note
Policy and upon which the Noteholders rely in purchasing their Notes.

                  (a) Organization and Good Standing. The Depositor is duly
         organized and validly existing as a Delaware business trust with power
         and authority to own its properties and to conduct its business as such
         properties are currently owned and such business is presently conducted
         and is proposed to be conducted pursuant to this Agreement and the
         Basic Documents.

                  (b) Due Qualification. The Depositor is duly qualified to do
         business and is in good standing, and has obtained all necessary
         licenses and approvals, in all jurisdictions in which the ownership or
         lease of its property, the conduct of its business and the performance
         of its obligations under this Agreement and the Basic Documents
         requires such qualification.

                  (c) Power and Authority. The Depositor has the trust power and
         authority to execute and deliver this Agreement and to carry out its
         terms; the Depositor has full power and authority to sell and assign
         the property to be sold and assigned to and deposited with the Trust,
         and the Depositor has duly authorized such sale and assignment and
         deposit to the Trust by all necessary trust action; and the execution,
         delivery and performance of this Agreement has been duly authorized by
         the Depositor by all necessary trust action.

                                       7
<PAGE>   13

                  (d) No Consent Required. To the best knowledge of the
         Depositor, no consent, license, approval or authorization or
         registration or declaration with, any Person or with any governmental
         authority, bureau or agency is required in connection with the
         execution, delivery or performance of this Agreement and the Basic
         Documents, except for such as have been obtained, effected or made.

                  (e) No Violation. The consummation of the transactions
         contemplated by this Agreement and the fulfillment of the terms hereof
         do not conflict with, result in any breach of any of the terms and
         provisions of, or constitute (with or without notice or lapse of time)
         a default under, the organizational documents of the Depositor, or any
         material indenture, agreement or other instrument to which the
         Depositor is a party or by which it is bound; nor result in the
         creation or imposition of any Lien upon any of its properties pursuant
         to the terms of any such indenture, agreement or other instrument
         (other than pursuant to the Basic Documents); nor violate any law or,
         to the best of the Depositor's knowledge, any order, rule or regulation
         applicable to the Depositor of any court or of any Federal or state
         regulatory body, administrative agency or other governmental
         instrumentality having jurisdiction over the Depositor or its
         properties.

                  (f) No Proceedings. There are no proceedings or investigations
         pending or, to its knowledge threatened against the Depositor before
         any court, regulatory body, administrative agency or other tribunal or
         governmental instrumentality having jurisdiction over it or its
         properties (i) asserting the invalidity of this Agreement or any of the
         Basic Documents, (ii) seeking to prevent the issuance of the
         Certificates or the Notes or the consummation of any of the
         transactions contemplated by this Agreement or any of the Basic
         Documents, (iii) seeking any determination or ruling that might
         materially and adversely affect its performance of its obligations
         under, or the validity or enforceability of, this Agreement or any of
         the Basic Documents, or (iv) seeking to adversely affect the federal
         income tax or other federal, state or local tax attributes of the Notes
         or the Certificate.

         SECTION 2.11. Tax Treatment. The Depositor, the Servicer and the
Certificateholder intend and agree to treat, and to take no action inconsistent
with the treatment of, the Notes as indebtedness for purposes of federal, state,
local and foreign income and franchise taxes and any other tax imposed on or
measured by net income. Furthermore, subject to the following paragraph, the
Depositor, the Servicer and the Certificateholder agree and intend to treat the
Trust as a security device only (or alternatively, if such characterization is
not respected for any applicable income or franchise tax purposes, as a
non-entity disregarded as an entity separate from its owner for such income or
franchise tax purposes under Treasury Regulations Section 301.7701-3(b)(ii) or
any similar provision of applicable law) and consistent with such intent the
Depositor, the Certificateholder and the Owner Trustee shall not file tax
returns on behalf of the Trust.

                                       8
<PAGE>   14

         Notwithstanding the above, in the event that any Class of Notes is
recharacterized by the Internal Revenue Service for federal income tax purposes
to represent an equity interest in the Trust, it is the intent and agreement of
the parties hereto that the Trust shall be treated for income and franchise tax
purposes as a partnership among the holders of such Notes and the
Certificateholder. In the event such a partnership is deemed to exist, any
interest accrued on the Notes in accordance with the terms thereof shall be
treated as guaranteed payments as defined in Code Section 707(c) and the
partnership's taxable income or loss (net of such guaranteed payments) shall be
allocated solely to the Certificateholder. If such treatment is not respected,
then the net income of the Trust for any month as determined for federal income
tax purposes (and each item of income, gain, loss and deduction entering into
the computation thereof) shall be allocated in such manner as to cause to the
greatest extent possible the Certificateholder and each Noteholder to recognize
net taxable income or loss at such time, and in such amounts, as each such
person would have recognized such income or loss if such Notes had been
respected as indebtedness and had not been recharacterized as an equity interest
in the Trust.

         SECTION 2.12. Covenants of the Depositor. The Depositor agrees and
covenants for the benefit of each Noteholder, the Certificateholder, the Insurer
and the Owner Trustee, during the term of this Agreement, and to the fullest
extent permitted by applicable law, that:

                  (a) it shall not cause or permit the Trust to create, incur or
         suffer to exist any indebtedness (other than any indebtedness pursuant
         to the Revolving Credit and Term Loan and Security Agreement) or engage
         in any activity, except, in each case, as permitted by this Agreement
         and the Basic Documents;

                  (b) it shall not, for any reason, institute proceedings for
         the Trust to be adjudicated a bankrupt or insolvent, or consent to the
         institution of bankruptcy or insolvency proceedings against the Trust,
         or file a petition seeking or consenting to reorganization or relief
         under any applicable federal or state law relating to the bankruptcy of
         the Trust, or consent to the appointment of a receiver, liquidator,
         assignee, trustee, sequestrator (or other similar official) of the
         Trust or a substantial part of the property of the Trust or cause or
         permit the Trust to make any assignment for the benefit of creditors,
         or admit in writing the inability of the Trust to pay its debts
         generally as they become due, or declare or effect a moratorium on the
         debt of the Trust or take any action in furtherance of any such action;

                  (c) it shall obtain from each counterparty to each Basic
         Document to which it or the Trust is a party and each other agreement
         entered into on or after the date hereof to which it or the Trust is a
         party, an agreement by each such counterparty that prior to the
         occurrence of the event specified in Section 9.1(e) such counterparty
         shall not institute against, or join any other Person in instituting
         against, it or the Trust, any bankruptcy, reorganization, arrangement,
         insolvency or liquidation proceedings or other similar proceedings
         under the laws of the United States or any state of the United States;

                  (d) it shall not, for any reason, withdraw or attempt to
         withdraw from this Agreement, dissolve, institute proceedings for it to
         be adjudicated a bankrupt or insolvent, or consent to the institution
         of bankruptcy or insolvency proceedings against it,

                                       9

         or file a petition seeking or consenting to reorganization or relief
         under any applicable federal or state law relating to bankruptcy, or
         consent to the appointment of a receiver, liquidator, assignee,
         trustee, sequestrator (or other similar official) of it or a
         substantial part of its property, or make any assignment for the
         benefit of creditors, or admit in writing its inability to pay its
         debts generally as they become due, or declare or effect a moratorium
         on its debt or take any action in furtherance of any such action;

                  (e) the operations of the Trust will be conducted in
         accordance with the following standards:

                           (A) prior to the date which is one year and one day
         after the Notes shall have been paid in full, the Depositor shall not
         institute any proceedings against, or join any Person in instituting
         against, the Trust any bankruptcy, reorganization, receivership
         arrangement, insolvency or liquidation proceedings or other similar
         proceedings under any federal or state bankruptcy or similar law. This
         Section 2.12(e) shall survive the termination of this Agreement and the
         Trust;

                           (B) so long as the Notes shall not have been
         indefeasibly paid in full, the Trust shall not:

                           (i) engage in any activities other than those set
         forth in Section 2.3 hereof;

         under the Basic Documents; (B) suffer or permit to exist any liens,
         claims or encumbrances on any of its property other than liens, claims
         or encumbrances permitted to be incurred by the Trust pursuant to the
         Basic Documents to which the Trust is a party; (C) make any advances,
         loans, extensions of credit, acquisitions or investments except as
         permitted by the Basic Documents to which the Trust is a party; (D)

         Trust, except on an arm's-length basis; or (E) own or acquire any stock

         Section 2.12 hereof;

                           (C) so long as the Notes shall not have been

         except to the extent required by the law of any applicable

         to the identity of the entity with which they are conducting
         activities; (C) hold itself out to the public as a legal entity
         separate and distinct from the Depositor or any Affiliate thereof; (D)

                           (ii) maintain all records and books of account so as
         to reflect the separate existence of the Trust and maintain bank
         accounts and assets separate from any other Person. The books of the
         Trust may be kept (subject to any provision contained in any applicable
         statutes) inside or outside the State of Delaware at such place or

         income tax information return in its capacity as holder of an interest
         in the Trust. The Certificateholder also hereby agrees that in its tax
         returns it will not take any position inconsistent with those taken in
         any tax returns that may be filed by the Trust;

                  (c) if the Certificateholder is other than an individual or

         Trust to make any assignment for the benefit of its creditors, or admit
         in writing its inability to pay its debts generally as they become due,
         or declare or effect a moratorium on its debt or take any action in
         furtherance of any such action.

         statements, cause appropriate footnotes to be added to such financial
         statement indicating that the assets of the Trust are not available to

                                   ARTICLE III

                      CERTIFICATE AND TRANSFER OF INTERESTS

         SECTION 3.1. Initial Ownership. Upon the formation of the Trust by the
contribution by the Depositor pursuant to Section 2.5 and until the later of (a)
the payment in full of all amounts payable to First Union National Bank pursuant
to the provisions of the Revolving Credit and Term Loan and Security Agreement
and (b) the sale of the Certificate by the Depositor, the Depositor, as the
Certificateholder, shall be the sole beneficiary of the Trust. The Certificate
shall not be divisible and shall always represent 100% of the beneficial
ownership interest of the Trust.

         SECTION 3.2. Signature on Certificate. The Certificate shall be
executed on behalf of the Trust by manual or facsimile signature of an
authorized officer of the Owner Trustee. A Certificate bearing the manual or
facsimile signature of an individual who was, at the time when such signature
shall have been affixed, authorized to sign on behalf of the Trust, shall be
validly issued and entitled to the benefit of this Agreement, notwithstanding
that such individual shall have ceased to be so authorized prior to the
authentication and delivery of such Certificate or did not hold such office at
the date of authentication and delivery of such Certificate. A transferee of the
Certificate shall become the Certificateholder, and shall be entitled to the
rights and subject to the obligations of the Certificateholder hereunder, upon
due registration of the Certificate in such transferee's name pursuant to
Section 3.4.

         SECTION 3.3. Authentication of Certificate. Concurrently with the
initial sale of the Receivables to the Trust pursuant to the Sale and Servicing
Agreement, the Owner Trustee shall cause the Certificate to be executed on
behalf of the Trust, authenticated and delivered to, or upon the written order
of, the Depositor, signed by its chairman of the board, its president or any
vice president, its treasurer or any assistant treasurer without further
corporate action by the Depositor. The Certificate shall neither entitle its
holder to any benefit under this Agreement nor

                                       14
<PAGE>   20

shall be valid for any purpose, unless there shall appear on the Certificate a
certificate of authentication substantially in the form set forth in Exhibit A,
executed by the Owner Trustee, by manual signature; such authentication shall
constitute conclusive evidence that such Certificate shall have been duly
authenticated and delivered hereunder. The Certificate shall be dated the date
of its authentication.

         SECTION 3.4. Registration of Transfer and Exchange of the Certificate.
The Certificate Registrar shall keep or cause to be kept, at the office or
agency maintained pursuant to Section 3.8, a Certificate Register in which,
subject to such reasonable regulations as it may prescribe, the Owner Trustee
shall provide for the registration of the Certificate and of transfers and
exchanges of the Certificate as herein provided. The Owner Trustee shall be the
initial Certificate Registrar.

         As a condition to the registration of any transfer of the Certificate,
the prospective transferee of such a Certificate shall represent to the Owner
Trustee and the Certificate Registrar the following:

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

                           (ii) It either (A) is not, and will not become, a
         partnership, S corporation or grantor trust for U.S. federal income tax
         purposes, or (B) is such an entity, but none of the direct or indirect
         beneficial owners of any of the interests in such transferee have
         allowed or caused, or will allow or cause, fifty percent (50%) or more
         of the value of such interests to be attributable to such transferee's
         ownership of the Certificate.

                           (iii) It understands that tax counsel to the Trust
         has provided an opinion substantially to the effect that the Trust will
         not be a publicly traded partnership taxable as a corporation for U.S.
         federal income tax purposes and that the validity of such opinion is
         dependent in part on the accuracy of the representations in paragraphs
         (i) and (ii) above.

         The Certificate has not been registered under the Securities Act of
1933, as amended (the "Securities Act") or any state securities law. The
Certificate Registrar shall not register the transfer of the Certificate unless
such resale or transfer complies with Section 3.9 and is pursuant to (a) Section
3.1 hereof and (b) an effective registration statement under the Securities Act
or is to the Seller or unless it shall have received (i) a representation letter
substantially in the form of Exhibit C hereto or (ii) such other representations
(or an Opinion of Counsel) satisfactory to the Owner Trustee to the effect that
such resale or transfer is made (A) in a transaction exempt from the
registration requirements of the Securities Act and applicable state securities
laws, or (B) to a person who the transferor of the Certificate reasonably
believes is a qualified institutional buyer (within the meaning of Rule 144A
under the Securities Act) that is aware that such resale or other transfer is
being made in reliance upon Rule 144A. Until such time as the Certificate shall
be

                                       15
<PAGE>   21

registered pursuant to a registration statement filed under the Securities Act,
the Certificate shall bear a legend as follows:

         THIS CERTIFICATE HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
1933, AS AMENDED (THE "SECURITIES ACT"), OR THE SECURITIES LAWS OF ANY STATE IN
RELIANCE UPON EXEMPTIONS PROVIDED BY THE SECURITIES ACT AND SUCH STATE
SECURITIES LAWS. NO RESALE OR OTHER TRANSFER OF THIS CERTIFICATE MAY BE MADE
UNLESS SUCH RESALE OR TRANSFER (A) IS MADE IN ACCORDANCE WITH SECTIONS 3.1 AND
3.4 OF THE TRUST AGREEMENT PERTAINING TO THE NATIONAL AUTO FINANCE 1999-1 TRUST
(THE "AGREEMENT") AND (B) IS MADE (i) PURSUANT TO AN EFFECTIVE REGISTRATION
STATEMENT UNDER THE SECURITIES ACT, (ii) IN A TRANSACTION EXEMPT FROM THE
REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND APPLICABLE STATE SECURITIES
LAWS, (iii) TO THE SELLER, OR (iv) TO A PERSON WHO THE TRANSFEROR REASONABLY
BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER WITHIN THE MEANING OF RULE 144A
UNDER THE SECURITIES ACT THAT IS AWARE THAT THE RESALE OR OTHER TRANSFER IS
BEING MADE IN RELIANCE ON RULE 144A, AND (C) UPON THE SATISFACTION OF CERTAIN
OTHER REQUIREMENTS SPECIFIED IN THE AGREEMENT. NEITHER THE SELLER, THE SERVICER,
THE TRUST NOR THE OWNER TRUSTEE (AS SUCH TERMS ARE DEFINED IN THE AGREEMENT) IS
OBLIGATED TO REGISTER THE CERTIFICATES UNDER THE SECURITIES ACT OR ANY
APPLICABLE STATE SECURITIES LAWS.

         The Certificate Registrar shall provide the Trust Collateral Agent with
the name and address of the Certificateholder on the Closing Date in the form
which such information is provided to the Certificate Registrar by the
Depositor. Upon any transfer of the Certificate, the Certificate Registrar shall
notify the Trust Collateral Agent of the name and address of the transferee in
writing, by facsimile, on the day of such transfer.

         Upon surrender for registration of transfer of the Certificate at the
office or agency maintained pursuant to Section 3.8, the Owner Trustee shall
execute, authenticate and deliver, in the name of the designated transferee or
transferees, a new Certificate dated the date of authentication by the Owner
Trustee or any authenticating agent.

         The 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 Certificateholder or his attorney duly authorized in writing, with such
signature guaranteed by an "eligible guarantor institution" meeting the
requirements of the Certificate Registrar, which requirements include membership
or participation in the Securities Transfer Agent's Medallion Program ("STAMP")
or such other "signature guarantee program" as may be determined by the
Certificate Registrar in addition to, or in substitution for, STAMP, all in
accordance with the Securities Exchange Act of 1934, as amended (the "Exchange
Act"). The Certificate surrendered for registration of transfer or exchange
shall be canceled and subsequently disposed of by the Owner Trustee in
accordance with its customary practice.

                                       16
<PAGE>   22

         No service charge shall be made for any registration of transfer or
exchange of the Certificate, but the Owner Trustee or the Certificate Registrar
may require payment of a sum sufficient to cover any tax or governmental charge
that may be imposed in connection with any transfer or exchange of the
Certificate.

         Notwithstanding the preceding provisions of this Section, the Owner
Trustee shall not be required to make, and the Certificate Registrar shall not
be required to register, transfers and exchanges of the Certificate for a period
of 15 days preceding the due date for any payment with respect to the
Certificate.

         The Seller shall not sell, transfer, assign, convey or pledge any
Certificate at any time subsequent to the Closing Date to any Person that is an
Affiliate of the Seller, unless, prior to such sale, transfer, assignment,
conveyance or pledge, the Seller delivers to the Insurer an Opinion of Counsel
substantially similar in form and substance to the Opinion of Counsel delivered
on the Closing Date as to non-consolidation of the assets and liabilities of (x)
the Seller and NAFI or (y) the Seller and any such Person that is an Affiliate
of the Seller (other than NAFI), of which a copy shall be delivered to each
Rating Agency.

         In furtherance of and not in limitation of the foregoing, the
Certificateholder, by acceptance of the Certificate, specifically acknowledges
that it has no right to or interest in any monies at any time held pursuant to
the Spread Account Agreement or prior to the release of such monies pursuant to
Section 5.7(a) of the Sale and Servicing Agreement or Section 3.03 of the Spread
Account Agreement, such monies being held in trust for the benefit of the [Class
A] Noteholders and the Insurer. Notwithstanding the foregoing, in the event that
it is ever determined that the monies held in the Spread Account constitute a
pledge of collateral, then the provisions of the Sale and Servicing Agreement
and the Spread Account Agreement shall be considered to constitute a security
agreement and the Seller and the Certificateholder hereby grant to the
Collateral Agent for the benefit of the Indenture Trustee on behalf of the
[Class A] Noteholders and the Insurer a first priority perfected security
interest in such amounts, to be applied as set forth in Section 3.03 of the
Spread Account Agreement. In addition, the Certificateholder, by acceptance of
the Certificate, hereby appoints the Depositor as its agent to pledge a first
priority perfected security interest in the Spread Account, and any amounts held
therein from time to time, to the Collateral Agent for the benefit of the
Indenture Trustee and the Insurer pursuant to the Spread Account Agreement and
agrees to execute and deliver such instruments of conveyance, assignment, grant,
confirmation, etc. as well as any financing statements, in each case that the
Insurer shall consider reasonably necessary in order to perfect the Collateral
Agent's Security Interest in the Collateral (as such terms are defined in the
Spread Account Agreement).

         SECTION 3.5. Mutilated, Destroyed, Lost or Stolen Certificate. If (a) a
mutilated Certificate shall be surrendered to the Certificate Registrar, or if
the Certificate Registrar shall receive evidence to its satisfaction of the
destruction, loss or theft of the Certificate and (b) there shall be delivered
to the Certificate Registrar, the Owner Trustee and (unless (i) an Insurer
Default shall have occurred and be continuing or (ii) the Class A Notes are no
longer outstanding, all amounts owing to the Insurer have been paid to it and
the term of the Class A Note Policy has expired) the Insurer, such security or
indemnity as may be required by them to save each of them

                                       17
<PAGE>   23

harmless, then in the absence of notice that the Certificate shall have been
acquired by a bona fide purchaser, the Owner Trustee on behalf of the Trust
shall execute and the Owner Trustee shall authenticate and deliver, in exchange
for or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a
new Certificate. In connection with the issuance of a new Certificate under this
Section, the Owner Trustee or the Certificate Registrar may require the payment
of a sum sufficient to cover any tax or other governmental charge that may be
imposed in connection therewith. Any duplicate Certificate issued pursuant to
this Section shall constitute conclusive evidence of the ownership of the Trust,
as if originally issued, whether or not the lost, stolen or destroyed
Certificate shall be found at any time.

         SECTION 3.6. Person Deemed the Certificateholder. Every Person by
virtue of becoming the Certificateholder in accordance with this Agreement and
the rules and regulations of the Certificate Registrar shall be deemed to be
bound by the terms of this Agreement. Prior to due presentation of the
Certificate for registration of transfer, the Owner Trustee, the Certificate
Registrar and the Insurer and any agent of the Owner Trustee, the Certificate
Registrar and the Insurer, respectively, may treat the Person in whose name the
Certificate shall be registered in the Certificate Register as the owner of the
Certificate for the purpose of receiving distributions pursuant to the Sale and
Servicing Agreement and for all other purposes whatsoever, and none of the Owner
Trustee, the Certificate Registrar or the Insurer nor any agent of the Owner
Trustee, the Certificate Registrar or the Insurer, shall be bound by any notice
to the contrary.

         SECTION 3.7. Access to Certificateholder's Name and Address. The Owner
Trustee shall furnish or cause to be furnished to the Servicer, the Depositor or
(unless (i) an Insurer Default shall have occurred and be continuing or (ii) the
Class A Notes are no longer outstanding, all amounts owing to the Insurer have
been paid to it and the term of the Class A Note Policy has expired) the
Insurer, within 15 days after receipt by the Owner Trustee of a request therefor
from such Person in writing, the name and address of the Certificateholder as of
the most recent Record Date. The Holder, by receiving and holding the
Certificate, shall be deemed to have agreed not to hold any of the Depositor,
the Servicer, the Owner Trustee or the Insurer or any agent thereof accountable
by reason of the disclosure of its name and address, regardless of the source
from which such information was derived.

         SECTION 3.8. Maintenance of Office or Agency. The Owner Trustee shall
maintain in Wilmington, Delaware, an office or offices or agency or agencies
where the Certificate may be surrendered for registration of transfer or
exchange and where notices and demands to or upon the Owner Trustee in respect
of the Certificate and the Basic Documents may be served. The Owner Trustee
initially designates its Corporate Trust Office for such purposes. The Owner
Trustee shall give prompt written notice to the Depositor, the Certificateholder
and the Insurer of any change in the location of the Certificate Register or any
such office or agency.

         SECTION 3.9. ERISA Restrictions. The Certificate may not be acquired by
or for the account of (i) an employee benefit plan (as defined in Section 3(3)
of the Employee Retirement Income Security Act of 1974, as amended ("ERISA"))
that is subject to the provisions of Title I of ERISA, (ii) a plan described in
Section 4975(e)(1) of the Code, or (iii) any entity whose underlying assets
include plan assets by reason of a plan's investment in the entity (each, a
"Benefit Plan"). The Certificate shall not be registered in the name of any
Holder unless the

                                       18
<PAGE>   24

Holder shall have represented and warranted, substantially in the form of
paragraph 8 to Exhibit C, that it is not a Benefit Plan.

         SECTION 3.10. Securities Matters. Notwithstanding anything contained
herein to the contrary, the Owner Trustee shall not be responsible for
ascertaining whether any transfer complies with the registration provisions or
exemptions from the Securities Act, the Exchange Act, applicable state
securities law or the Investment Company Act; provided, however, that if a
Certificate is specifically required to be delivered to the Owner Trustee by a
purchaser or transferee of a Certificate, the Owner Trustee shall be under a
duty to examine the same to determine whether it conforms to the requirements of
this Agreement and shall promptly notify the party delivering the same if such
certificate does not so conform.

         SECTION 3.11. Pledge of Certificate. The parties hereto hereby
acknowledge that the Depositor has, pursuant to the Revolving Credit and Term
Loan and Security Agreement, pledged the Certificate to First Union National
Bank. Upon receipt of notice from First Union National Bank to the effect that
an Event of Default has occurred and is continuing under the Revolving Credit
and Term Loan and Security Agreement, (i) the Owner Trustee shall upon request,
pay to First Union National Bank directly any and all amounts that the
Certificateholder would be entitled to receive hereunder and (ii) First Union
National Bank may exercise its rights under that agreement and notwithstanding
any other provision of this Agreement to the contrary, upon the request of First
Union National Bank, the outstanding Certificate shall be deemed canceled and a
new Certificate shall be issued and registered in the name or upon the order of
First Union National Bank, and without further action, First Union National Bank
shall become the Certificateholder.

                                   ARTICLE IV

                         VOTING RIGHTS AND OTHER ACTIONS

         SECTION 4.1. Prior Notice to Holder with Respect to Certain Matters.
With respect to the following matters, the Owner Trustee shall not take action
unless at least 10 days before the taking of such action, the Owner Trustee
shall have notified the Certificateholder in writing of the proposed action and
the Certificateholder shall not have notified the Owner Trustee in writing prior
to the 10th day after such notice is given that the Certificateholder has
withheld consent or provided alternative direction:

                           (a) the election by the Trust to file an amendment to
         the Certificate of Trust (unless such amendment is required to be filed
         under the Business Trust Statute or unless such amendment would not
         materially and adversely affect the interest of the Holder);

                           (b) the amendment of the Indenture by a supplemental
         indenture in circumstances where the consent of any Noteholder is
         required;

                                       19
<PAGE>   25

                           (c) the amendment of the Indenture by a supplemental
         indenture in circumstances where the consent of any Noteholder is not
         required and such amendment materially adversely affects the interest
         of the Certificateholder; or

                           (d) except pursuant to Section 13.1(b) of the Sale
         and Servicing Agreement, the amendment, change or modification of the
         Sale and Servicing Agreement, except to cure any ambiguity or defect or
         to amend or supplement any provision in a manner that would not
         materially adversely affect the interest of the Certificateholder.

         The Owner Trustee shall notify the Certificateholder in writing of any
appointment of a successor Note Registrar, Trust Collateral Agent or Certificate
Registrar within five Business Days thereof.

         SECTION 4.2. Action by Certificateholder with Respect to Certain
Matters. The Owner Trustee shall not have the power, except upon the direction
of the Insurer or, (i) in the event that an Insurer Default shall have occurred
and be continuing or (ii) the Class A Notes are no longer outstanding, all
amounts owing to the Insurer have been paid to it and the term of the Class A
Note Policy has expired, the Security Majority in accordance with the Basic
Documents, to (a) remove the Servicer under the Sale and Servicing Agreement or
(b) except as expressly provided in the Basic Documents, sell the Receivables
after the termination of the Indenture. The Owner Trustee shall take the actions
referred to in the preceding sentence only upon written instructions signed by
the Insurer or the Security Majority, as the case may be, and the furnishing of
indemnification satisfactory to the Owner Trustee by the Certificateholder.

         SECTION 4.3. Action by Certificateholder with Respect to Bankruptcy.
Until the Notes have been indefeasibly paid in full, the Owner Trustee shall not

consent of the Insurer (unless (i) an Insurer Default shall have occurred and be
continuing or (ii) the Class A Notes are no longer outstanding, all amounts

Policy has expired) or the Security Majority upon an Insurer Default (or if the
Class A Notes are no longer outstanding, all amounts owing to the Insurer have
been paid to it and the term of the Class A Note Policy has expired). One year
and one day after the Notes have been indefeasibly paid in full, all amounts due
to the Insurer under the Insurance Agreement have been paid in full, the term of
the Class A Note Policy has expired and the Trust Collateral Agent has
surrendered the Class A Note Policy to the Insurer, the Owner Trustee shall not
have the power to, and shall not, commence any proceeding or other actions
contemplated by Section 2.12(d) relating to the Trust without the prior written
consent of the Certificateholder and the delivery to the Owner Trustee by the
Certificateholder of written certification that the Certificateholder reasonably
believes that the Trust is insolvent.

         SECTION 4.4. Restrictions on Certificateholder's Power. (a) The
Certificateholder shall not direct the Owner Trustee to take or refrain from
taking any action if such action or inaction would be contrary to any obligation
of the Trust or the Owner Trustee under this Agreement or any of the Basic
Documents or would be contrary to Section 2.3 or otherwise contrary to law, nor
shall the Owner Trustee be obligated to follow any such direction, if given.

                           (b) The Certificateholder (other than the Depositor
         as sole Certificateholder) shall not have any right by virtue, or by
         availing itself, of any provisions of this Agreement to institute any
         suit, action, or proceeding in equity or at law upon or under or with
         respect to this Agreement or any Basic Document, unless the
         Certificateholder is the Instructing Party pursuant to Section 6.3 and
         unless the Certificateholder previously shall have given to the Owner
         Trustee a written notice of default and of the continuance thereof, as
         provided in this Agreement, and also unless the Certificateholder shall
         have made written request upon the Owner Trustee to institute such
         action, suit or proceeding in its own name as Owner Trustee under this
         Agreement and shall have offered to the Owner Trustee such reasonable
         indemnity as it may require against the costs, expenses and liabilities
         to be incurred therein or thereby, and the Owner Trustee, for 30 days
         after its receipt of such notice, request, and offer of indemnity,
         shall have neglected or refused to institute any such action, suit, or
         proceeding, and during such 30-day period no request or waiver
         inconsistent with such written request has been given to the Owner
         Trustee pursuant to and in compliance with this Section or Section 6.3;
         it being understood and intended, and being expressly covenanted by the
         Certificateholder with the Owner Trustee, that the Certificateholder
         shall not have any right in any manner whatever by virtue, or by
         availing itself of any provisions of this Agreement to enforce any
         right under this Agreement, except in the manner provided in this
         Agreement. For the protection and enforcement of the provisions of this
         Section 4.4, the Certificateholder and the Owner Trustee shall be
         entitled to such relief as can be given either at law or in equity.

         SECTION 4.5. Rights of Insurer. Notwithstanding anything to the
contrary in the Basic Documents, unless (A) either (i) an Insurer Default shall
have occurred and be continuing or (ii) the Class A Notes are no longer
outstanding, all amounts owing to the Insurer have been paid to it and the term
of the Class A Note Policy has been expired and (B) it shall have received the
prior written consent of the Security Majority, the Owner Trustee shall not (i)
remove the Servicer, the Custodian, the Backup Servicer, or any Sub-Servicer,
(ii) initiate any claim, suit or proceeding by the Trust or compromise any
claim, suit or proceeding brought by or against the Trust, other than with
respect to the enforcement of any Receivable or any rights of the Trust
thereunder, (iii) authorize the merger or consolidation of the Trust with or
into any other business trust or other entity (other than in accordance with
Section 3.10 of the Indenture), (iv) amend the Certificate of Trust, or (v)
amend this Agreement in accordance with Section 11.1 of this Agreement.

         SECTION 5.1. Accounting and Records to the Noteholders, the
Certificateholder, the Internal Revenue Service and Others. Subject to Sections
12.1(b)(iii) and 12.1(c) of the Sale and Servicing Agreement, the Depositor
shall (a) maintain (or cause to be maintained) the books of the Trust on a
calendar year basis on the accrual method of accounting, including, without
limitation, any allocations of net income under Section 2.11, (b) deliver (or
cause to be delivered) to the Certificateholder, as may be required by the Code
and applicable Treasury Regulations, such information in the Depositor's
possession as may be requested (including Schedule K-1, if

                                       21
<PAGE>   27

applicable) to enable the Certificateholder to prepare its federal, state and
local income and franchise tax returns, (c) file or cause to be filed, if
necessary, such tax returns relating to the Trust (including, if applicable, a
partnership information return, Form 1065), and direct the Owner Trustee or the
Servicer, as the case may be, to make such elections as may from time to time be
required or appropriate under any applicable state, local or federal statute or
rule or regulation thereunder so as to maintain the Trust's characterization as
a security device or non-entity, as the case may be, or if applicable, as a
partnership, for federal income tax purposes, and (d) collect or cause to be
collected any withholding tax as described in and in accordance with Section
5.8(c) of the Sale and Serving Agreement with respect to income or distributions
to the Certificateholder and the appropriate forms relating thereto. The Owner
Trustee or the Servicer, as the case may be, shall make all elections pursuant
to this Section as directed in writing by the Depositor. The Owner Trustee shall
upon request sign all tax information returns provided to it in execution form,
if any, filed pursuant to this Section 5.1 and any other returns as may be
required by law, and in doing so shall rely entirely upon, and shall have no
liability for information provided by, or calculations provided by, the
Depositor or the Servicer. Notwithstanding anything to the contrary above, none
of the parties hereto shall make the election provided in Treasury Regulations
Section 301.7701-3(c) to have the Trust classified as an association taxable as
a corporation.

         SECTION 5.2. Signature on Returns; Tax Matters Partner. (a)
Notwithstanding the provisions of Section 5.1 and in the event that the Trust is
characterized as a partnership, the Owner Trustee shall pursuant to an
instruction sign on behalf of the Trust the tax returns of the Trust provided to
it in execution form, unless applicable law requires a Certificateholder to sign
such documents, in which case such documents shall be signed by the Depositor.

                           (b) In the event that the Trust is characterized as a
         partnership, the Depositor shall be the "tax matters partner" of the
         Trust pursuant to the Code.

         SECTION 5.3. Note Purchase Agreements. The Owner Trustee is hereby
authorized to execute and deliver the Note Purchase Agreements with respect to
the Notes.

                                   ARTICLE VI

                      AUTHORITY AND DUTIES OF OWNER TRUSTEE

         SECTION 6.1. General Authority. The Owner Trustee is authorized and
directed to execute and deliver the Basic Documents to which the Trust is named
as a party and each certificate or other document attached as an exhibit to or
contemplated by the Basic Documents to which the Trust is a signatory and any
amendment thereto, in each case, in such form as the Depositor shall approve as
evidenced conclusively by the Owner Trustee's execution thereof, and on behalf
of the Trust, to direct the Indenture Trustee to authenticate and deliver the
Notes in the aggregate principal amount of $53,125,000. 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
Instructing Party recommends with respect to the Basic Documents, which the
Instructing Party hereby agrees shall be consistent with the terms of the Basic
Documents.

                                       22
<PAGE>   28

         SECTION 6.2. General Duties. It shall be the duty of the Owner Trustee
to discharge (or cause to be discharged) all of its responsibilities pursuant to
the terms of this Agreement and to administer the Trust in the interest of the
Holder, 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 Basic
Documents to the extent the Servicer has agreed in the Sale and Servicing
Agreement to perform any act or to discharge any duty of the Trust or the Owner
Trustee hereunder or under any Basic Document, and the Owner Trustee shall not
be liable for the default or failure of the Servicer to carry out its
obligations under the Sale and Servicing Agreement.

         SECTION 6.3. Action upon Instruction. (a) Subject to Article IV and the
terms of the Spread Account Agreement, the Insurer (so long as (i) an Insurer
Default shall not have occurred and be continuing and (ii) either the Class A
Notes are still outstanding, amounts owing to the Insurer under the Insurance
Agreement have not been paid to it or the term of the Class A Note Policy has
not expired) or the Security Majority (if (i) an Insurer Default shall have
occurred and be continuing or (ii) the Class A Notes are no longer outstanding,
all amounts owing to the Insurer have been paid to it and the Class A Note
Policy has expired) (the "Instructing Party") shall have the exclusive right to
direct the actions of the Owner Trustee in the management of the Trust, so long
as such instructions are not inconsistent with the express terms set forth
herein or in any Basic Document. The Instructing Party shall not instruct the
Owner Trustee in a manner inconsistent with this Agreement or the Basic
Documents.

                           (b) The Owner Trustee shall not be required to take
         any action hereunder or under any 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 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 any Basic Document, 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
         in violation of this Agreement or the Basic Documents, as it shall deem
         to be in the best interests of the Certificateholder, 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 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

                                       23
<PAGE>   29

         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 10 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
         in violation of this Agreement or the Basic Documents, as it shall deem
         to be in the best interests of the Certificateholder, and shall have no
         liability to any Person for such action or inaction.

         SECTION 6.4. 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 Owner 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 6.3; and no implied duties or obligations
shall be read into this Agreement or any 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 filing for the Trust with the Securities
and Exchange Commission or to record this Agreement or any 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 on any part
of the Owner Trust Estate that result from actions by, or claims against, the
Owner Trustee (solely in its individual capacity) and that are not related to
the ownership or the administration of the Owner Trust Estate.

         SECTION 6.5. 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 Owner Trust Estate except (i) in
accordance with the powers granted to and the authority conferred upon the Owner
Trustee pursuant to this Agreement, (ii) in accordance with the Basic Documents
or (iii) in accordance with any document or instruction delivered to the Owner
Trustee pursuant to the Basic Documents.

         SECTION 6.6. Restrictions. The Owner Trustee shall not (a) take any
action that is in violation of the purposes of the Trust set forth in Section
2.3, or (b) take any action (including, without limitation, participating in the
establishment of a market or the inclusion of the Trust's interests thereon,
within the meaning of Treasury Regulation Section 1.7704-1(d)(1)) that, to the
actual knowledge of the Owner Trustee, would result in the Trust becoming
taxable as a corporation or a publicly traded partnership for federal income tax
purposes. The Certificateholder shall not direct the Owner Trustee to take
action that would violate the provisions of this Section.

         any Certificateholder];

                  (c) no provision of this Agreement or any Basic Document 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 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) as provided in Section 8.4 hereof, under no circumstances

                  (e) the Owner Trustee shall not be responsible for, or in
         respect of, the validity or sufficiency of this Agreement, or for the
         due execution hereof by the Depositor, or for the form, character,
         genuineness, sufficiency, value or validity of any of the Owner Trust
         Estate, or for, or in respect of, the validity or sufficiency of the
         Basic Documents, other than the certificate of authentication on the
         Certificate, and the Owner Trustee shall in no event assume or incur
         any liability, duty or obligation to the Depositor, the Insurer,

                                       25
<PAGE>   31

         Trustee, Trust Collateral Agent, the Collateral Agent, any Noteholder
         or to the Certificateholder, other than as expressly provided for
         herein and in the Basic Documents;

                  (f) the Owner Trustee shall not be liable for the default or
         misconduct of the Depositor, the Insurer, the Trustee, the Trust
         Collateral Agent or the Servicer under any of the Basic Documents, or
         otherwise, and the Owner Trustee shall have no obligation or liability
         to perform the obligations under this Agreement or the Basic Documents
         that are required to be performed by the Depositor under this
         Agreement, by the Trustee under the Indenture, or the Trust Collateral
         Agent or the Servicer under the Sale and Servicing Agreement; and

                  (g) the Owner Trustee shall be under no obligation to exercise
         any of the rights or powers vested in it by this Agreement, or to
         institute, conduct or defend any litigation under this Agreement, or
         otherwise, or in relation to this Agreement or any Basic Document, at
         the request, order or direction of the Instructing Party or the
         Certificateholder, unless such Instructing Party or the
         Certificateholder 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 Owner Trustee to perform any discretionary
         act enumerated in this Agreement or in any Basic Document shall not be
         construed as a duty, and the Owner Trustee shall not be answerable for
         other than its negligence, bad faith or willful misconduct in the
         performance of any such act.

         SECTION 7.2. Furnishing of Documents. The Owner Trustee shall furnish
to the Certificateholder promptly upon receipt of a written request therefor,

warranties in purchasing the Notes) and the Insurer (which shall have relied on
such representations and warranties in issuing the Class A Note Policy), that:

                  (a) It is a Delaware banking corporation, duly organized and
         validly existing in good standing under the laws of the State of
         Delaware. It 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 execution and delivery by it of this Agreement, and this Agreement
         will be executed and delivered by one of its officers who is duly
         authorized to execute and deliver this Agreement on its behalf.

                  (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

                                       26
<PAGE>   32

         any of the terms or provisions hereof will contravene any federal or
         Delaware state 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
         by-laws or any indenture, mortgage, contract, agreement or instrument
         to which it is a party or by which any of its properties may be bound.

         SECTION 7.4. Reliance; Advice of Counsel. (a) The Owner Trustee shall
incur no liability to anyone in acting upon any signature, instrument, notice,
resolution, request, consent, order, certificate, report, opinion, bond or other
document or paper believed by it to be genuine and reasonably believed by it to
be signed by the proper party or parties. The Owner Trustee may accept a
certified copy of a resolution of the board of 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 the 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,
secretary 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.

                           (b) In the exercise or administration of the trusts
         hereunder and in the performance of its duties and obligations under
         this Agreement or the Basic Documents, the Owner Trustee (i) may act
         directly or through its agents or attorneys pursuant to agreements
         entered into with any of them, and the Owner 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. The Owner Trustee shall not be liable for anything
         done, suffered or omitted in good faith by it in accordance with the
         written opinion or advice of any such counsel, accountants or other
         such persons and according to such opinion not contrary to this
         Agreement or any Basic Document.

         SECTION 7.5. Not Acting in Individual Capacity. Except as provided in
this Article VII, in accepting the trusts hereby created, Wilmington Trust
Company acts solely as Owner Trustee hereunder and not in its individual
capacity and all Persons having any claim against the Owner Trustee by reason of
the transactions contemplated by this Agreement or any Basic Document shall look
only to the Owner Trust Estate for payment or satisfaction thereof.

         SECTION 7.6. Owner Trustee Not Liable for Certificate or Receivables.
The recitals contained herein and in the Certificates (other than the
authenticity of the signature and countersignature of the Owner Trustee on the
Certificate) 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, of
any Basic Document or of the Certificate (other than the signature and
countersignature of the Owner Trustee on the Certificate) or the Notes, or of
any Receivable 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 Receivable, or the perfection and priority of any security

                                       27
<PAGE>   33

interest created by any Receivable in any Financed Vehicle or the maintenance of
any such perfection and priority, or for or with respect to the sufficiency of
the Owner Trust Estate or its ability to generate the payments to be distributed
to the Certificateholder 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 Receivable on any computer or other
record thereof; the validity of the assignment of any Receivable to the Trust or
of any intervening assignment; the completeness of any Receivable; the
performance or enforcement of any Receivable; the compliance by the Depositor,
the Servicer or any other Person 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 Trustee or the Servicer or any
subservicer taken in the name of the Owner Trustee.

         SECTION 7.7. Owner Trustee May Own Certificates and Notes. The Owner
Trustee in its individual or any other capacity may become the owner or pledgee
of the Certificate or the Notes and may deal with the Depositor, the Trustee and
the Servicer in banking transactions with the same rights as it would have if it
were not Owner Trustee.

         SECTION 7.8. Payments from Owner Trust Estate. All payments to be made
by the Owner Trustee under this Agreement or any of the Basic Documents to which
the Trust or the Owner Trustee is a party shall be made only from the income and
proceeds of the Owner Trust Estate and only to the extent that the Owner Trustee
shall have received income or proceeds from the Owner Trust Estate to make such
payments in accordance with the terms hereof. Wilmington Trust Company, or any

Notwithstanding anything contained to the contrary, neither Wilmington Trust
Company or any successor thereto, nor the Owner Trustee shall be required to
take any action in any jurisdiction other than in the State of Delaware if the
taking of such action will, even after the appointment of a co-trustee or
separate trustee in accordance with Section 10.5 hereof, (i) require the consent
or approval or authorization or order of or the giving of notice to, or the
registration with or the taking of any other action in respect of, any state or
other governmental authority or agency of any jurisdiction other than the State
of Delaware; (ii) result in any fee, tax or other governmental charge under the
laws of the State of Delaware becoming payable by Wilmington Trust Company (or
any successor thereto); or (iii) subject Wilmington Trust Company (or any
successor thereto) to personal jurisdiction in any jurisdiction other than the
State of Delaware for causes of action arising from acts unrelated to the
consummation of the transactions by Wilmington Trust Company (or any successor
thereto) or the Owner Trustee, as the case may be, contemplated hereby.

                          COMPENSATION OF OWNER TRUSTEE

         SECTION 8.1. Owner Trustee's Fees and Expenses. Wilmington Trust
Company shall receive as compensation for its services hereunder such fees as
have been separately agreed upon before the date hereof between the Depositor
and Wilmington Trust Company, and Wilmington Trust Company shall be entitled to
be reimbursed by the Depositor for its other reasonable expenses hereunder,
including the reasonable compensation, expenses and disbursements of such
agents, representatives, experts and counsel as the Owner Trustee may employ in
connection with the exercise and performance of its rights and its duties
hereunder and under the Basic Documents.

obligor for, and shall indemnify the Owner Trustee (in its individual and trust
capacities) and its officers, directors, successors, assigns, agents and
servants (collectively, the "Indemnified Parties") from and against, any and all
liabilities, obligations, losses, damages, taxes, claims, actions and suits, and
any and all reasonable costs, expenses and disbursements (including reasonable
legal fees and expenses) of any kind and nature whatsoever (collectively,
"Expenses") which may (in its trust or individual capacities) at any time be
imposed on, incurred by, or asserted against the Owner Trustee or any
Indemnified Party in any way relating to or arising out of this Agreement, the
Basic Documents, the Owner Trust Estate, the administration of the Owner Trust
Estate or the action or inaction of the Owner Trustee hereunder, except only

Trustee from and against Expenses arising or resulting from any of the matters
described in the third sentence of Section 7.1. The indemnities contained in
this Section and the rights under Section 8.1 shall survive the resignation or
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
unreasonably withheld. In the event the Owner Trustee shall receive payment from
any Person with respect to any Expenses following the receipt of payment from

payment to the Depositor without any action by or on behalf of the Depositor or
any Person.

         SECTION 8.3. Payments to the Owner Trustee. Any amounts paid to the

Agreement or any Basic Document, the Owner Trustee agrees in its individual
capacity and in its capacity as Owner Trustee for the Trust that all obligations
of the Trust to the Owner Trustee individually or as Owner Trustee for the Trust
shall be recourse to the Owner Trust Estate only and specifically shall not be
recourse to the assets of the Certificateholder.

                         TERMINATION OF TRUST AGREEMENT

         SECTION 9.1. Termination of Trust Agreement. (a) This Agreement and the
Trust shall wind up, dissolve and terminate and be of no further force or effect
upon the latest of (i) the maturity or other liquidation of the last Receivable
(including the purchase by the Servicer at its option of the corpus of the Trust
as described in Section 11.1 of the Sale and Servicing Agreement) and the
subsequent distribution of amounts in respect of such Receivables as provided in
the Basic Documents or (ii) the payment to the Certificateholder of all amounts
required to be paid to it pursuant to this Agreement, the indefeasible payment
in full of all amounts payable to the Noteholders pursuant to the Indenture and
the other Transaction Documents and the payment to the Insurer of all amounts
payable or reimbursable to it pursuant to the Sale and Servicing Agreement;
provided, however, that the rights to indemnification under Section 8.2 and the
rights under Section 8.1 shall survive the termination of the Trust. The
Servicer shall promptly notify the Owner Trustee and the Insurer of any
prospective termination pursuant to this Section 9.1. The bankruptcy,
liquidation, dissolution, death or incapacity of the Certificateholder shall not
(x) operate to terminate this Agreement or the Trust, nor (y) entitle the
Certificateholder'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 Owner Trust Estate, nor (z) otherwise affect the
rights, obligations and liabilities of the parties hereto.

                  (a) Except as provided in clause (a), neither the Depositor
         nor any other Certificateholder shall be entitled to revoke or
         terminate the Trust.

                  (b) Notice of any termination of the Trust, specifying the
         Distribution Date upon which the Certificateholder shall surrender its
         Certificate to the Trust Collateral Agent for payment of the final
         distribution and cancellation, shall be given by the Owner Trustee by
         letter to the Certificateholder mailed within five Business Days of
         receipt of notice of such termination from the Servicer given pursuant
         to Section 11.1(c) of the Sale and Servicing Agreement, stating (i) the
         Distribution Date upon or with respect to which final payment of the
         Certificate shall be made upon presentation and surrender of the
         Certificate at the office of the Trust Collateral Agent therein
         designated, (ii) the amount of any such final payment, (iii) that the
         Record Date otherwise applicable to such Distribution Date is not
         applicable, payments being made only upon presentation and surrender of
         the Certificate at the office of the Trust Collateral Agent therein
         specified, and (iv) interest will cease to accrue on the Certificate.
         The Owner Trustee shall give such notice to the Certificate Registrar
         (if other than the Owner Trustee) and the Trust Collateral Agent at the
         time such notice is given to the Certificateholder. Upon presentation
         and surrender of the Certificate, the Trust Collateral Agent shall
         cause to be distributed to the Certificateholder amounts distributable
         on such Distribution Date pursuant to Section 5.7 of the Sale and
         Servicing Agreement.

         In the event that the Certificateholder shall not have surrendered its
Certificate for cancellation within six months after the date specified in the
above mentioned written notice, the

                                       30
<PAGE>   36

Owner Trustee shall give a second written notice to the Certificateholder to
surrender the Certificate for cancellation and receive the final distribution
with respect thereto. If within one year after the second notice the Certificate
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 Certificateholder concerning surrender of the 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 shall be distributed, subject to applicable escheat laws, by the
Owner Trustee to the Depositor and Holder shall thereafter look solely to the
Depositor for payment.

                  (c) Subject to the requirements of the Business Trust Statute,
         any funds remaining in the Trust after funds for final distribution
         have been distributed or set aside for distribution shall be
         distributed by the Owner Trustee to the Depositor.

                  (d) Upon the winding up of the Trust and its termination, the
         Owner Trustee shall cause the Certificate of Trust to be canceled by
         filing a certificate of cancellation with the Secretary of State in
         accordance with the provisions of Section 3810 of the Business Trust
         Statute.

                  (e) Written notice of the termination of this Agreement and
         the Trust shall be given to each Rating Agency by the Owner Trustee.

                                    ARTICLE X

             SUCCESSOR OWNER TRUSTEES AND ADDITIONAL OWNER TRUSTEES

         SECTION 10.1. Eligibility Requirements for Owner Trustee. The Owner

Section 3807(a) of the Business Trust Statute; (ii) authorized to exercise
corporate trust powers; (iii) having a combined capital and surplus of at least
$50,000,000 and subject to supervision or examination by Federal or State
authorities; (iv) having (or having a parent which has) a rating of at least
Baa3 by Moody's and A-1 by Standard & Poors; and (v) acceptable to (A) the
Insurer in its sole discretion, so long as (i) an Insurer Default shall not have
occurred and be continuing and (ii) either the Class A Notes are still
outstanding, amounts owing to the Insurer under the Insurance Agreement have not
been paid in full or the term of the Class A Note Policy has not expired or (B)
acceptable to the Security Majority (instead of the Insurer, in the event that
either (i) an Insurer Default shall have occurred and be continuing or (ii) the
Class A Notes are no longer outstanding, all amounts owing to the Insurer have
been paid to it and the term of the Class A Note Policy has expired). 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,

                                       31
<PAGE>   37

the Owner Trustee shall resign immediately in the manner and with the effect
specified in Section 10.2.

         SECTION 10.2. 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 Certificateholder, the Insurer, the
Noteholders and the Servicer. Upon receiving such notice of resignation, the
Depositor shall promptly appoint a successor Owner Trustee, meeting the
qualifications set forth in Section 10.1 herein, 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 of the Rating
Agencies that the proposed appointment will not result in an increased capital
charge to the Insurer by either of the Rating Agencies. 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 10.1 and shall fail to resign after
written request therefor by the Depositor, 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 Depositor, with the consent of (A) the Insurer, so long as
(i) an Insurer Default shall not have occurred and be continuing and (ii) either
the Class A Notes are still outstanding, amounts owing to the Insurer under the
Insurance Agreement have not been paid in full or the term of the Class A Note
Policy has not expired or (B) the Security Majority, in the event that either
(i) an Insurer Default shall have occurred and be continuing or (ii) the Class A
Notes are no longer outstanding, all amounts owing to the Insurer have been paid
to it and the term of the Class A Note Policy has expired), may remove the Owner
Trustee. If the Depositor shall remove the Owner Trustee under the authority of
the immediately preceding sentence, the Depositor shall promptly appoint a
successor Owner Trustee, meeting the qualifications set forth in Section 10.1
herein, by written instrument, in duplicate, one copy of which instrument shall
be delivered to the outgoing Owner Trustee so removed, one copy to the Insurer
and one copy to the successor Owner Trustee, and payment of 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 10.3 and payment of all fees and expenses owed to
the outgoing Owner Trustee. The Depositor shall provide notice of such
resignation or removal of the Owner Trustee to each of the Rating Agencies.

         SECTION 10.3. Successor Owner Trustee. Any successor Owner Trustee
appointed pursuant to Section 10.2 shall execute, acknowledge and deliver to the
Depositor, the Servicer, the Insurer, the Noteholders 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,

                                       32
<PAGE>   38

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
Depositor 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 10.1.

         Upon acceptance of appointment by a successor Owner Trustee pursuant to
this Section, the Servicer shall mail notice of the successor of such Owner
Trustee to the Certificateholder, the Trustee, the Noteholders and the Rating
Agencies. If the Servicer shall fail to mail such notice within 10 days after
acceptance of appointment by the successor Owner Trustee, the successor Owner
Trustee shall cause such notice to be mailed at the expense of the Servicer.

         SECTION 10.4. 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, provided
such corporation shall be eligible pursuant to Section 10.1, 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
further that the Owner Trustee shall mail notice of such merger or consolidation
to the Rating Agencies.

         SECTION 10.5. 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 Owner Trust Estate or any Financed Vehicle may at the time be located,
the Servicer 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 Owner Trustee and the Insurer to act as co-trustee, jointly with the Owner
Trustee, or separate trustee or separate trustees, of all or any part of the
Owner 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 Servicer and
the Owner Trustee may consider necessary or desirable. If the Servicer shall not
have joined in such appointment within 15 days after the receipt by it of a
request so to do, the Owner Trustee subject, unless (i) an Insurer Default shall
have occurred and be continuing or (ii) the Class A Notes are no longer
outstanding and all amounts owing to the Insurer have been paid to it, to the
approval of the Insurer (which approval shall not be unreasonably withheld)
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 trustee pursuant to Section 10.1 and no notice of the appointment of
any co-trustee or separate trustee shall be required pursuant to Section 10.3.

                                       33
<PAGE>   39

         Each separate trustee and co-trustee shall, to the extent permitted by
law, be appointed and act subject to the following provisions and conditions:

                  (i) all rights, powers, duties and obligations conferred or
         imposed upon the Owner Trustee shall be conferred upon and exercised or
         performed by the Owner Trustee and such separate trustee or co-trustee
         jointly (it being understood that such separate trustee or co-trustee
         is not authorized to act separately without the Owner Trustee joining
         in such act), except to the extent that under any law of any
         jurisdiction in which any particular act or acts are to be performed,
         the Owner Trustee shall be incompetent or unqualified to perform such
         act or acts, in which event such rights, powers, duties and obligations
         (including the holding of title to the Trust or any portion thereof in
         any such jurisdiction) shall be exercised and performed singly by such
         separate trustee or co-trustee, but solely at the direction of the
         Owner Trustee;

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

                  (iii) the Servicer 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 Servicer and the Insurer.

         Any separate trustee or co-trustee may at any time appoint the Owner
Trustee, its agent or attorney-in-fact with full power and authority, to the
extent not prohibited by law, to do any lawful act under or in respect of this
Agreement on its behalf and in its name. If any separate 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 trustee.

Rating Agencies, to the extent such amendment materially and adversely affects
the interests of any Noteholder, with the consent of the Noteholders evidencing
not less than a majority of the Outstanding Amount of the Notes and, the consent
of the Certificateholder (which consent of any Noteholder or the
Certificateholder given pursuant to this Section or pursuant to any other

reduce the aforesaid percentage of the Outstanding Amount of the Notes and the
Certificate, the holders of which are required to consent to any such amendment,
without the consent of the holders of all the outstanding Notes and the
Certificateholder.

         Promptly after the execution of any such amendment or consent, the
Owner Trustee shall furnish a true copy of such amendment or consent to each
Noteholder, the Certificateholder, the Trustee and each of the Rating Agencies.

the Noteholders, the Insurer or the Trustee, such party or parties must approve
the particular form of such proposed amendment. The manner of obtaining such
consents (and any other consent of the Certificateholder provided for in this
Agreement or in any other Basic Document) and of evidencing the authorization of
the execution thereof by the Certificateholder shall be subject to such
reasonable requirements as the Owner Trustee may prescribe. Promptly after the

such parties or their assets, except as otherwise agreed or may be expressly set
forth or contemplated in this Agreement, the Certificate or the Basic Documents.

                  OWNER TRUSTEE'S CERTIFICATE OF AUTHENTICATION

         This is the Certificate referred to in the within mentioned Trust
Agreement.

WILMINGTON TRUST COMPANY, not in its individual capacity but solely as Owner
Trustee

by ________________________________ Authenticating Agent

by_______________________________

         The Trust was created pursuant to a Trust Agreement dated as of
September 1, 1999 (the "Trust Agreement"), between the Depositor and Wilmington
Trust Company, as owner trustee (the "Owner Trustee"), a summary of certain of
the pertinent provisions of which is set forth below. To the extent not
otherwise defined herein, the capitalized terms used herein have the meanings
assigned to them in the Trust Agreement.

         This Certificate is the duly authorized Certificate designated as a
"Trust Certificate" (herein called the "Certificate"). This Certificate is
issued under and is subject to the terms, provisions and conditions of the Trust
Agreement, to which Trust Agreement the holder of this Certificate by virtue of
the acceptance hereof assents and by which such holder is bound. The property of
the Trust includes a pool of retail installment sale contracts secured by new
and used automobiles or light duty trucks (the "Receivables"), all monies due
thereunder on or after the Cutoff Date, security interests in the vehicles
financed thereby, certain bank accounts and the proceeds thereof, proceeds from
claims on certain insurance policies and certain other rights under the Trust
Agreement and the Sale and Servicing Agreement, all right to and interest of the
Depositor in and to the Sale Agreement dated as of September 1, 1999 between
National Auto Funding Trust II and National Financial Auto Funding Trust and all
proceeds of the foregoing.

         Under the Trust Agreement, there will be distributed on the 21st day of
each month or, if such 21st day is not a Business Day, the next Business Day
(the "Distribution Date"), commencing on October 21, 1999, to the Person in
whose name this Certificate is registered at the close of business on the last
Business Day of the calendar month immediately preceding the month in which such
Distribution Date occurs (the "Record Date"), the amount to be distributed to
the Certificateholder on such Distribution Date.

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

         The holder of this Certificate, by acceptance of this Certificate,
specifically acknowledges that it has no right to or interest in any monies at
any time held pursuant to the Spread Account Agreement or prior to the release
of such monies pursuant to Section 5.7(a) of the Sale and Servicing Agreement,
such monies being held in trust for the benefit of the Class A Noteholders

<PAGE>   47

and the Insurer. Notwithstanding the foregoing, in the event that it is ever
determined that the monies held in the Spread Account constitute a pledge of
collateral, then the provisions of the Sale and Servicing Agreement and the
Spread Account Agreement shall be considered to constitute a security agreement
and the holder of this Certificate hereby grants to the Trust Collateral Agent
for the benefit of the Trustee and the Insurer, a first priority perfected
security interest in such amounts, to be applied as set forth in Section 3.03 of
the Spread Account Agreement. In addition, the Certificateholder, by acceptance
of the Certificate, hereby appoints the Seller as its agent to pledge a first
priority perfected security interest in the Spread Account, and any amounts held
therein from time to time to the Collateral Agent for the benefit of the Trustee
and the Insurer pursuant to the Spread Account Agreement, and agrees to execute
and deliver such instruments of conveyance, assignment, grant, confirmation,
etc., as well as any financing statements, in each case that the Insurer shall
consider reasonably necessary in order to perfect the Trust Collateral Agent's
security interest in the Collateral.

         It is the agreement and intent of the Depositor, the Servicer, and the
Certificateholder that, for purposes of income and franchise taxes, the Trust
will be treated as a security device only, or alternatively, if such
characterization is not respected for any applicable income or franchise tax
purposes, the Trust shall be treated solely for such income or franchise tax
purposes as a non-entity disregarded as an entity separate from its owner under
Treasury Regulations Section 301.7701-3(b)(ii) or any similar provision of
applicable law; provided, however, that if any Class of Notes is treated as an
equity interest in the Trust for any applicable income or franchise tax
purposes, it is the intention and agreement of the Depositor, the Servicer and
the Certificateholder that the Trust will be treated as a partnership for such
income and franchise tax purposes and the Certificateholder and the Noteholders
whose Class of Notes are treated as equity interests will be treated as partners
in the partnership. The Depositor and any other Certificateholder, by acceptance
of the Certificate, agrees to treat, and to take no action inconsistent with the
treatment of, the Certificate for such tax purposes as a partnership interest in
the Trust. The Certificateholder, by its acceptance of the Certificate,
covenants and agrees that it will not at any time institute against the Trust or
the Depositor, or join in any institution against the Trust or the Depositor of,
any bankruptcy, reorganization, arrangement, insolvency or liquidation
proceedings, or other proceedings under any United States Federal or state
bankruptcy or similar law in connection with any obligations relating to the
Certificate, the Notes, the Trust Agreement or any of the Basic Documents.

         Distributions on this Certificate will be made as provided in the Sale
and Servicing Agreement by the Trust Collateral Agent by wire transfer or check
mailed to the Certificateholder of record in the Certificate Register without
the presentation or surrender of this 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 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 Certificate at the office or agency
maintained for the purpose by the Owner Trustee in the Corporate Trust Office.

<PAGE>   48

         Reference is hereby made to the further provisions of this 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 or facsimile
signature, this Certificate shall not entitle the holder hereof to any benefit
under the Trust Agreement or the Sale and Servicing Agreement or be valid for
any purpose.

         THIS 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.

         IN WITNESS WHEREOF, the Owner Trustee, on behalf of the Trust and not
in its individual capacity, has caused this Certificate to be duly executed.

                        NATIONAL AUTO FINANCE 1999-1 TRUST

                        By: WILMINGTON TRUST COMPANY, not in its individual
                            capacity but solely as Owner Trustee

                            (Reverse of Certificate)

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

         The Trust Agreement permits, with certain exceptions therein provided,
the amendment thereof and the modification of the rights and obligations of the
Depositor and the rights of the Certificateholder under the Trust Agreement at
any time by the Depositor and the Owner Trustee with the prior written consent
of Financial Security Assurance Inc. (the "Insurer") so long as (i) no Insurer
Default has occurred and is continuing and (ii) either the Class A Notes are
outstanding or amounts owing to the Insurer under the Insurance Agreement have
not been paid in full, and with the consent of the Certificateholder and the
holders of the Notes evidencing not less than a majority of the outstanding
Notes and the percentage ownership interest of the Trust. Any such consent by
the holder of this Certificate shall be conclusive and binding on such holder
and on all future holders of this Certificate and of any Certificate issued upon
the transfer hereof or in exchange hereof or in lieu hereof whether or not
notation of such consent is made upon this Certificate. The Trust Agreement also
permits the amendment thereof, in certain limited circumstances, without the
consent of the Certificateholder (other than the Depositor or the Insurer).

         As provided in the Trust Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registerable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices or agencies of the Certificate Registrar maintained by
the Owner Trustee in the Corporate Trust Office, 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 Certificates
evidencing the same class and percentage ownership interest in the Trust will be
issued to the designated transferee. The initial Certificate Registrar appointed
under the Trust Agreement is Wilmington Trust Company.

         The Certificate is issuable only as a registered Certificate. As
provided in the Trust Agreement and subject to certain limitations therein set
forth, the Certificate is exchangeable for a new Certificate, 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.

<PAGE>   50

         The Owner Trustee, the Certificate Registrar and any agent of the Owner
Trustee, the Certificate Registrar or the Insurer may treat the person in whose
name this Certificate is registered as the owner hereof for all purposes, and
none of the Owner Trustee, the Certificate Registrar nor 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 the
Certificateholder of all amounts required to be paid to it pursuant to the Trust
Agreement and the Sale and Servicing Agreement and the disposition of all
property held as part of the Trust. The Servicer of the Receivables may at its
option purchase the corpus of the Trust at a price specified in the Sale and
Servicing Agreement, and such purchase of the Receivables and other property of
the Trust will effect a transfer of the Certificate; however, such right of
purchase is exercisable, subject to certain restrictions, only as of the last
day of any Monthly Period as of which the Pool Balance is 10% or less of the
Original Pool Balance.

         The Certificate may not be acquired by, and the Holder hereof by
holding this Certificate agrees that it is not (a) an employee benefit plan (as
defined in Section 3(3) of ERISA) that is subject to the provisions of Title I
of ERISA, (b) a plan described in Section 4975(e) (1) of the Code or (c) any
entity whose underlying assets include plan assets by reason of a plan's
investment in the entity (each, a "Benefit Plan"). The Holder of the interest
represented by this Certificate, and each person to whom this Certificate is
transferred, is required to represent and warrant to the Owner Trustee that it
is not a Benefit Plan.

         The undersigned acknowledges and agrees that (i) it has neither
acquired nor will it transfer the Certificate or cause the Certificate to be
marketed on or through an "established securities market" within the meaning of
Section 7704(b)(1) of the Code, including, without limitation, an over-the-
counter-market or an interdealer quotation system that regularly disseminates
firm buy or sell quotations; (ii) it either (A) is not, and will not become, a
partnership, S corporation or grantor trust for U.S. federal income tax
purposes, or (B) is such an entity, but none of the direct or indirect
beneficial owners of any of the interests in such transferee have allowed or
caused, or will allow or cause, fifty percent (50%) or more of the value of such
interests to be attributable to such transferee's ownership of the Certificate;
and (iii) it understands that tax counsel to the Trust has provided an opinion
substantially to the effect that the Trust will not be treated as a publicly
traded partnership taxable as a corporation for U.S. federal income tax purposes
and that the validity of such opinion is dependent in part on the accuracy of
the representations in paragraphs (i) and (ii) above.

         The recitals contained herein shall be taken as the statements of the
Depositor or the Servicer, as the case may be, 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 Certificate or of any
Receivable or related document.

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

<PAGE>   51

holder hereof to any benefit under the Trust Agreement or the Sale and Servicing
Agreement or be valid for any purpose.

(the "Rule 144A Information").

         6. The Purchaser certifies that it will comply with all applicable
federal and state securities laws in connection with any subsequent resale by
the Purchaser of the Trust Certificate.

         7. The Purchaser understands and acknowledges that the Trust

1933, as amended, or any state securities laws and may be resold only if (a) the
Trust Certificate is registered pursuant to the provisions of the Securities Act
of 1933, as amended, and such state securities laws, or (b) if an exemption from
such registration is available. The Purchaser understands and acknowledges that
the Trust is not required to register the Trust Certificate and that any

obligated to provide Rule 144A Information.

         8. The Purchaser additionally represents that it is not, and is not
acquiring the Trust Certificate for the account of, (i) an employee benefit plan

investment in the entity.

         9. The Purchaser additionally represents that (i) it has neither
acquired nor will it transfer the Trust Certificate or cause the Trust

limitation, an over-the-counter-market or an interdealer quotation system that
regularly disseminates firm buy or sell quotations; (ii) it either (A) is not,
and will not become, a partnership, S corporation or grantor trust for U.S.

indirect beneficial owners of any of the interests in such transferee have
allowed or caused, or will allow or cause, fifty percent (50%) or more of the
value of such interests to be attributable to such transferee's ownership of the
Trust Certificate; and (iii) it understands that tax counsel to the Trust has
provided an opinion substantially to the effect that the Trust will not be
treated as a publicly traded partnership taxable as a corporation for U.S.
federal income tax purposes and that the validity of such opinion is dependent
in part on the accuracy of the representations in paragraphs (i) and (ii) above.
