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

Percentage Interests of the Trust Certificates (hereinafter referred to as
"APPLICANTS"), apply in writing to the Trust Agent, and such application states
that the Applicants desire to communicate with other Holders with respect to
their rights hereunder or under the Trust Certificates and such application is
accompanied by a copy of the communication that such Applicants propose to
transmit, then the Trust Agent shall, within five Business Days after the
receipt of such application, afford such Applicants access, during normal

business hours, to the current list of Holders. Each Holder, by receiving and
holding a Trust Certificate, agrees with the Depositor, the Owner Trustee and
the Trust Agent that none of the Depositor, the Owner Trustee or the Trust Agent

to its name and address hereunder, regardless of the source from which such
information was derived.

authorized denomination, substantially of the tenor of the definitive Trust
Certificates in lieu of which they are issued. If temporary Trust Certificates
are issued, the Depositor will cause definitive Trust Certificates to be
prepared without unreasonable delay. After the preparation of definitive Trust
Certificates, the temporary Trust Certificates shall be exchangeable for
definitive Trust Certificates upon surrender of the temporary Trust Certificates
at the office or agency to be maintained as provided in Section 3.08, without
charge to the Holder. Upon surrender for cancellation of any one or more
temporary Trust Certificates, the Owner Trustee shall execute, authenticate and
deliver (or shall cause the Trust Agent, as its authenticating agent, to
authenticate and deliver) in exchange therefor a like Percentage Interest of
definitive Trust Certificates in authorized denominations. Until so exchanged,
the temporary Trust Certificates shall in all respects be entitled to the same
benefits hereunder as definitive Trust Certificates.

     Section 3.10 Appointment of Paying Agent. The Owner Trustee, on behalf of
the Trust, hereby appoints the Trust Agent as Paying Agent under this Agreement.
The Paying Agent shall make distributions to Holders from the Certificate
Distribution Account pursuant to Section 5.02 hereof and shall report the
amounts of such distributions to the Owner Trustee. The Paying Agent shall have
the revocable power to withdraw funds from the Certificate Distribution Account
for the purpose of making the distributions referred to above. The Owner Trustee
on behalf of the Trust may revoke such power and remove the Paying Agent if the
Owner Trustee is directed in writing to do so by the Administrator. Each Paying
Agent shall be permitted to resign as Paying Agent upon 30 days' written notice
to the Trust. In the event that the Trust Agent shall no longer be the Paying
Agent, the Administrator shall appoint a successor to act as Paying Agent (which
shall be a bank or trust company). The Administrator shall cause such successor
Paying Agent or any additional Paying Agent appointed by the Administrator to
execute and deliver to the Trust an instrument in which such successor Paying
Agent or additional Paying Agent shall agree with the Trust that, as Paying
Agent, such successor Paying Agent or additional Paying Agent will hold all
sums, if any, held by it for payment to the Holders in trust for the benefit of
the Holders entitled thereto until such sums shall be paid to such Holders. The
Paying Agent shall return all unclaimed funds to the Trust and upon removal of a
Paying Agent such Paying Agent shall also return all funds in its possession to
the Trust. The provisions of Sections 7.01, 7.03, 7.04, 8.01 and 8.02 shall
apply to the Trust

proceedings, and withholding payment of such tax, if permitted by law, pending
the outcome of such proceedings). The amount of any withholding tax imposed with
respect to a Holder shall be treated as cash distributed to such Holder at the
time it is withheld by the Trust and remitted to the appropriate taxing

possibility that withholding tax is payable with respect to a distribution, the
Trust Agent shall withhold such amounts in accordance with this paragraph (c).

in the amount to be distributed to such Holder pursuant to such Holder's Trust
Certificates or, if the Holder shall have timely notified the Trust Agent with
the proper instructions, by wire transfer.

     Section 5.04 No Segregation of Monies; No Interest. Subject to Sections
5.01 and 5.02, monies received by the Trust Agent hereunder need not be

deposited under such general conditions as may be prescribed by law, and the
Trust Agent shall not be liable for any interest thereon.

Internal Revenue Service and Others. The Trust Agent shall (a) maintain (or
cause to be maintained) the books of the Trust on a calendar year basis and the

the Code and applicable Treasury Regulations, such information as may be
required (including Schedule K-1, if applicable) to enable each Holder to
prepare its federal and state income tax returns, (c) file such tax returns
relating to the Trust (including a partnership information return, IRS Form
1065, if applicable) and make such elections as from time to time may be
required or appropriate under any applicable state or federal statute or any
rule or regulation thereunder so as to maintain the Trust's characterization as
a partnership, if applicable, for federal income tax purposes, (d) cause such
tax returns to be signed in the manner required by law and (e) collect or cause
to be collected any withholding tax as described in and in accordance with

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

     Section 6.02 General Duties. Subject to the provisions and limitations of
Sections 2.03 and 2.06;

     (a) it shall be the duty of the Owner Trustee to discharge (or cause to be

of its responsibilities pursuant to the terms of this Agreement and the other
Basic Documents to which the Trust is a party and to administer the Trust in the
interest of the Holders, subject to the Basic Documents and in accordance with
the provisions of this Agreement. Notwithstanding the foregoing, the Owner
Trustee shall be deemed to have discharged its duties and responsibilities
hereunder and under the other Basic Documents to the extent the Administrator or
the Trust Agent has agreed in the Administration Agreement or this Agreement,
respectively, to perform any act or to discharge any duty of the Owner Trustee
or the Trust hereunder or under any Basic Document, and the Owner Trustee shall
not be held liable for the default or failure of the Administrator or the Trust
Agent to carry out its obligations under the Administration Agreement or this

<PAGE>   21

     (b) Neither the Owner Trustee nor the Trust Agent shall be required to take
any action hereunder or under any other Basic Document if the Owner Trustee or
the Trust Agent, as applicable, shall have reasonably determined, or shall have
been advised by counsel, that such action is likely to result in liability on
the part of the Owner Trustee or the Trust Agent, as applicable, or is contrary
to the terms hereof or of any other Basic Document or is otherwise contrary to
law.

     (c) Whenever the Owner Trustee or the Trust Agent is unable to decide
between alternative courses of action permitted or required by the terms of this
Agreement or under any other Basic Document, the Owner Trustee or the Trust
Agent, as applicable, shall promptly give notice (in such form as shall be
appropriate under the circumstances) to the Holders requesting instruction as to
the course of action to be adopted, and to the extent the Owner Trustee or the
Trust Agent, as applicable, acts in good faith in accordance with any written
instruction of the Holders received, the Owner Trustee or the Trust Agent, as

reasonably may be specified in such notice or may be necessary under the
circumstances) it may, but shall be under no duty to, take or refrain from
taking such action not inconsistent with this Agreement and the other Basic
Documents, and shall have no liability to any Person for such action or
inaction.

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

applicable, is a party, except as expressly provided by the terms of this
Agreement or in any document or written instruction received by the Owner
Trustee or the Trust Agent, as applicable, pursuant to Section 6.03; and no
implied duties or obligations shall be read into this Agreement or any other
Basic Document against the Owner Trustee or the Trust Agent. Neither the Owner

financing or continuation statement in any public office at any time or to
otherwise perfect or maintain the perfection of any security interest or lien
granted to it hereunder or to prepare or file any Commission filing for the
Trust or to record this Agreement or any other Basic Document. Each of the Owner
Trustee and the Trust Agent nevertheless agrees that


                                      -17-

not related to the ownership or the administration of the Trust Estate or the
Grant of any portion thereof to the Indenture Trustee pursuant to the Indenture.

shall take any action (i) that is inconsistent with the purposes of the Trust
set forth in Section 2.03 or (ii) that, to the actual knowledge of the Owner
Trustee or the Trust Agent, as applicable, would result in the Trust's becoming
taxable as a corporation for federal or state income tax purposes. The Holders
shall not direct the Owner Trustee or the Trust Agent to take action that would
violate the provisions of this Section.

surrendered for cancellation, the Trust Agent may take appropriate steps, or may
appoint an agent to take appropriate steps, to contact the remaining Holders
concerning surrender of their Trust Certificates, and the cost thereof shall be
paid out of the funds and other assets that shall remain subject to this
Agreement. Any funds remaining in the Trust after exhaustion of such remedies
shall be distributed by the Trust Agent to the Depositor.

     (e) 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

having a combined capital and surplus of at least $50,000,000 and subject to
supervision or examination by federal or state authorities; and having (or
having a parent that has) a rating of at least A-1 by Standard & Poor's. If such
corporation shall publish reports of condition at least annually pursuant to law
or to the requirements of the aforesaid supervising or examining authority, then

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

<PAGE>   29

be eligible in accordance with the provisions of this Section, the Owner Trustee
shall resign immediately in the manner and with the effect specified in Section
10.02.

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

     If at any time the Owner Trustee shall cease to be eligible in accordance
with the provisions of Section 10.01 and shall fail to resign after written
request therefor by the Administrator, or if at any time the Owner Trustee shall
be legally unable to act, or shall be adjudged bankrupt or insolvent, or a
receiver of the Owner Trustee or of its property shall be appointed, or any
public officer shall take charge or control of the Owner Trustee or of its
property or affairs for the purpose of rehabilitation, conservation or
liquidation, or if at any time the Owner Trustee shall have breached any
representation or warranty contained in Section 7.03(a) (without regard to any
knowledge qualification), then the Administrator may remove the Owner Trustee.
If the Owner Trustee shall be removed under the authority of the immediately
preceding sentence, the Administrator shall promptly appoint a successor Owner
Trustee by written instrument, in duplicate, one copy of which instrument shall
be delivered to the outgoing Owner Trustee so removed and one copy to the
successor Owner Trustee, and shall pay all fees owed to the outgoing Owner
Trustee.

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

     Section 10.03 Successor Owner Trustee. Any successor Owner Trustee
appointed pursuant to Section 10.02 shall execute, acknowledge and deliver to
the Administrator and to its predecessor Owner Trustee an instrument accepting
such appointment under this Agreement, and thereupon the resignation or removal
of the predecessor Owner Trustee shall become effective, and such successor
Owner Trustee, without any further act, deed or conveyance, shall become fully
vested with all the rights, powers, duties and obligations of its predecessor
under this Agreement, with like effect as if originally named as Owner Trustee.
The predecessor Owner Trustee shall upon payment of its fees and expenses
deliver to the successor Owner Trustee all documents and statements and monies
held by it under this Agreement; and the Administrator and the predecessor Owner
Trustee shall execute and deliver such instruments and do such other things as
may reasonably be required for fully and certainly vesting and confirming in the
successor Owner Trustee all such rights, powers, duties and obligations.

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


                                      -25-


<PAGE>   30

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

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

     Section 10.05 Appointment of Co-Trustee or Separate Trustee.
Notwithstanding any other provisions of this Agreement, at any time, for the
purpose of meeting any legal requirements of any jurisdiction in which any part
of the Trust Estate may at the time be located, the Administrator and the Owner
Trustee acting jointly shall have the power and shall execute and deliver all
instruments to appoint one or more Persons approved by the Administrator and
Owner Trustee to act as co-trustee, jointly with the Owner Trustee, or as
separate trustee or separate trustees, of all or any part of the Trust Estate,
and to vest in such Person, in such capacity, such title to the Trust or any
part thereof and, subject to the other provisions of this Section, such powers,
duties, obligations, rights and trusts as the Administrator and the Owner
Trustee may consider necessary or desirable. If the Administrator shall not have
joined in such appointment within 15 days after the receipt by it of a request
so to do, the Owner Trustee shall have the power to make such appointment. No
co-trustee or separate trustee under this Agreement shall be required to meet
the terms of eligibility as a successor Owner Trustee, provided that such
co-trustee or successor trustee must be acceptable to the Rating Agency and no
notice of the appointment of any co-trustee or separate trustee shall be
required pursuant to Section 10.03.

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

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


                                      -26-


<PAGE>   31

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

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

     Any notice, request or other writing given to the Owner Trustee shall be
deemed to have been given to each of the then separate trustees and co-trustees,
as effectively as if given to each of them. Every instrument appointing any
separate trustee or co-trustee shall refer to this Agreement and the conditions
of this Article. Each separate trustee and co-trustee, upon its acceptance of
the trusts conferred, shall be vested with the estates or property specified in
its instrument of appointment, either jointly with the Owner Trustee or
separately, as may be provided therein, subject to all the provisions of this
Agreement, specifically including every provision of this Agreement relating to
the conduct of, affecting the liability of or affording protection to, the Owner
Trustee. Each such instrument shall be filed with the Owner Trustee and a copy
thereof given to the Administrator.

     Any separate trustee or co-trustee may at any time appoint the Owner
Trustee as its agent or attorney-in-fact with full power and authority, to the
extent not prohibited by law, to do any lawful act under or in respect of this
Agreement on its behalf and in its name. If any separate trustee or co-trustee
shall die, become incapable of acting, resign or be removed, all of its estates,
properties, rights, remedies and trusts shall vest in and be exercised by the
Owner Trustee, to the extent permitted by law, without the appointment of a new
or successor co-trustee or separate trustee.

     The Owner Trustee on behalf of the Trust hereby appoints The Chase
Manhattan Bank as Trust Agent for the purpose of establishing and maintaining
the Certificate Distribution Account and making the distributions therefrom to
the persons entitled thereto pursuant to Section 5.02 of this Agreement and for
purposes of performing the other duties specified to be performed by the Trust
Agent under this Agreement and the other Basic Documents. The Trust Agent, in
its capacity as Trust Agent, shall not have any rights, duties or obligations
except as expressly provided in this Agreement and the Sale and Assignment
Agreement.

     The Trust Agent may at any time resign and be discharged from the trusts
hereby created by giving 30 days' written notice thereof to the Owner Trustee
and the Administrator. Upon receiving such notice of resignation, the Owner
Trustee shall promptly appoint a successor Trust Agent by written instrument, in
duplicate, one copy of which instrument shall be delivered to the resigning
Trust Agent and one copy to the successor Trust Agent. If no successor Trust
Agent shall have been so appointed and have accepted appointment within 30 days
after giving of such notice of resignation, the Owner Trustee shall assume the
duties of Trust Agent.
