president, any vice president, secretary or any assistant treasurer, without
further corporate action by the Depositor, in authorized denominations. No Trust
Certificate shall entitle its Holder to any benefit under this Agreement or be
valid for any purpose unless there shall appear on such Trust Certificate a
certificate of authentication substantially in the form set forth in Exhibit A,
executed by the Owner Trustee or [____________], as the Owner Trustee's
authenticating agent, by manual signature; such authentication shall constitute
conclusive evidence that such Trust Certificate shall have been duly

transfer or exchange shall be accompanied by a written instrument of transfer in
form satisfactory to the Owner Trustee and the Certificate Registrar duly
executed by the Holder or such Holder's attorney duly authorized in writing.
Each Trust Certificate surrendered for registration of transfer or exchange
shall be cancelled and subsequently disposed of by the Owner Trustee in
accordance with its customary practice.

         No service charge shall be made for any registration of transfer or
exchange of Trust Certificates, 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 Trust Certificates.

         The preceding provisions of this Section notwithstanding, the Owner
Trustee shall not make, and the Certificate Registrar shall not register

satisfaction of the destruction, loss or theft of any Trust Certificate and (b)
there shall be delivered to the Certificate Registrar and the Owner Trustee such
security or indemnity as may be required by them to save each of them harmless,

the Owner Trustee or [_______________], as the Owner Trustee's authenticating
agent, shall authenticate and deliver, in exchange for or in lieu of any such
mutilated, destroyed, lost or stolen Trust Certificate, a newn Trust Certificate
of like tenor and denomination. In connection with the issuance of any new Trust
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

Owner Trustee, and such application states that the applicants desire to
communicate with other Certificateholders with respect to their rights under
this Agreement or under the Trust Certificates and such application is
accompanied by a copy of the communication that such applicants propose to
transmit, then the Owner Trustee shall, within five Business Days after the
receipt of such application, afford such applicants access during normal
business hours to the current list of Certificateholders. Each Holder, by
receiving and holding a Trust Certificate, shall be deemed to have agreed not to
hold any of the Depositor, the Company, the Certificate Registrar or the Owner

that the Paying Agent shall have failed to perform its obligations under this
Agreement in any material respect. The Paying Agent initially shall be
[___________], and any co-paying agent chosen by [___________] and acceptable to
the Owner Trustee. [____________] shall be permitted to resign as Paying Agent
upon 30 days' written notice to the Owner Trustee. In the event that

appoint a successor to act as Paying Agent (which shall be a bank or trust
company). The Owner Trustee shall cause such successor Paying Agent or any
additional Paying Agent appointed by the Owner Trustee to execute and deliver to

upon instructions or directions of Holders of Trust Certificates evidencing a
specified percentage of the Certificate Balance, the Clearing Agency shall be
deemed to represent such percentage only to the extent that it has received
instructions to such effect from Certificate Owners and/or Clearing Agency
Participants owning or representing, respectively, such required percentage of
the beneficial interest in the Trust Certificates and has delivered such
instructions to the Owner Trustee.

     Section 3.12  Notices to Clearing Agency.   Whenever a notice or other
                   --------------------------

writing that the continuation of a book-entry system through the Clearing Agency
is no longer in the best interest of the Certificate Owners, then the Clearing
Agency shall notify all Certificate Owners and the Owner Trustee of the
occurrence of any such event and of the availability of the Definitive Trust
Certificates to Certificate Owners requesting the same. Upon surrender to the
Owner Trustee of the typewritten Trust Certificate or Trust Certificates
representing the Book-Entry Trust Certificates by the Clearing Agency,
accompanied by registration instructions, the Owner Trustee shall execute and
authenticate the Definitive Trust Certificates in accordance with the
instructions of the Clearing Agency. Neither the Certificate Registrar nor the
Owner Trustee shall be liable for any delay in delivery of such instructions and
may conclusively rely on, and shall be protected in relying on, such
instructions. Upon the issuance of Definitive Trust Certificates, the Owner
Trustee shall recognize the Holders of the Definitive Trust Certificates as

                                   ARTICLE V

                  APPLICATION OF TRUST FUNDS; CERTAIN DUTIES
                  ------------------------------------------

     Section 5.01 Establishment of Trust Account. The Owner Trustee, for the
                  ------------------------------
benefit of the Certificateholders, shall establish and maintain in the name of
the Trust an Eligible Deposit Account (the "Certificate Distribution Account"),
bearing a designation clearly indicating that the funds deposited therein are
held for the benefit of the Certificateholders.

     The Owner Trustee shall possess all right, title and interest in all funds
on deposit from time to time in the Certificate Distribution Account and in all
proceeds thereof. Except as otherwise expressly provided herein, the Certificate
Distribution Account shall be under the sole dominion and control of the Owner
Trustee for the benefit of the Certificateholders. If, at any time, the
Certificate Distribution Account ceases to be an Eligible Deposit Account, the
Owner Trustee (or the Depositor on behalf of the Owner Trustee, if the
Certificate Distribution Account is not then held by the Owner Trustee or an
affiliate thereof) shall within 10 Business Days (or such longer period, not to
exceed 30 calendar days, as to which each Rating Agency may consent) establish a
new Certificate Distribution Account as an Eligible Deposit Account and shall
transfer any cash and/or any investments to such new Certificate Distribution
Account.

     Section 5.02 Application of Trust Funds. (a) On each Distribution Date, the
                  --------------------------

Certificateholder the statement or statements provided to the Owner Trustee by
the Master Servicer pursuant to Section [____] of the Sale and Servicing
Agreement with respect to such Distribution Date.

     (c)  In the event that any withholding tax is imposed on the Trust's
payment (or allocations of income) to an Owner, such tax shall reduce the amount
otherwise distributable to the Owner in accordance with this Section. The Owner
Trustee is hereby authorized and directed to retain from amounts otherwise
distributable to the Owners sufficient funds for the payment of any tax that is
legally owed by the Trust (but such authorization shall not prevent the Owner
Trustee from contesting any such tax in appropriate proceedings, and withholding
payment of such tax, if

                                      16
<PAGE>

permitted by law, pending the outcome of such proceedings). The amount of any
withholding tax imposed with respect to an Owner shall be treated as cash
distributed to such Owner at the time it is withheld by the Trust and remitted
to the appropriate taxing authority. If there is a possibility that withholding
tax is payable with respect to a distribution (such as a distribution to a non-
U.S. Owner), the Owner Trustee may in its sole discretion withhold such amounts
in accordance with this paragraph (c).

     Section 5.03 Method of Payment. Subject to Section 9.01(c), distributions
                  -----------------
required to be made to Certificateholders on any Distribution Date shall be made
to each Certificateholder of record on the preceding Record Date either by wire
transfer, in immediately available funds, to the account of such Holder at a
bank or other entity having appropriate facilities therefor, if such
Certificateholder shall have provided to the Certificate Registrar appropriate
written instructions at least five Business Days prior to such Distribution Date
and such Holder's Trust Certificates in the aggregate evidence a denomination of
not less than $[____________], or, if not, by check mailed to such
Certificateholder at the address of such holder appearing in the Certificate
Register.

     Section 5.04 No Segregation of Moneys; No Interest. Subject to Sections
                  -------------------------------------

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

     Section 5.05 Accounting and Reports to the Noteholders, Owners, the
                  ------------------------------------------------------
Internal Revenue Service and Others. The Owner Trustee shall (a) maintain (or
-----------------------------------
cause to be maintained) the books of the Trust on a calendar year basis and the
accrual method of accounting, (b) deliver to each Owner, as may be required by
the Code and applicable Treasury Regulations, such information as may be
required (including Schedule K-1) to enable each Owner to prepare its federal
and state income tax returns, (c) file such tax returns relating to the Trust
(including a partnership information return, IRS Form 1065) and make such
elections as from time to time may be required or appropriate under any
applicable state or federal statute or any rule or regulation thereunder so as
to maintain the Trust's characterization as a partnership for federal income tax
purposes, (d) cause such tax returns to be signed in the manner required by law
and (e) collect or cause to be collected any withholding tax as described in and
in accordance with Section 5.02(c) with respect to income or distributions to
Owners. The Owner Trustee shall elect under Section 1278 of the Code to include
in income currently any market discount that accrues with respect to the
Mortgage Loans. The Owner Trustee shall not make the election provided under
Section 754 of the Code.

     Section 5.06 Signature on Returns; Tax Matters Partner. (a) The Owner
                  -----------------------------------------
Trustee shall sign on behalf of the Trust the tax returns of the Trust, unless
applicable law requires an Owner to sign such documents, in which case such
documents shall be signed by the Company.

     (b)  The Company shall be designated the "tax matters partner" of the Trust
pursuant to Section 6231(a)(7)(A) of the Code and applicable Treasury
Regulations.

                                  ARTICLE VI

                     AUTHORITY AND DUTIES OF OWNER TRUSTEE
                     -------------------------------------

         Section 6.01 General Authority. The Owner Trustee is authorized and
                      -----------------
directed to execute and deliver the Basic Documents to which the Trust is to be
a party and each certificate or other document attached as an exhibit to or
contemplated by the Basic Documents to which the Trust is to be a party and any
amendment or other agreement or instrument, in each case, in such form as the
Company shall approve, 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. 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 the Basic Documents to which the Trust is a
party and to administer the Trust in the interest of the Owners, subject to the
Basic Documents and in accordance with the provisions of this Agreement.
Notwithstanding the foregoing, the Owner Trustee shall be deemed to have
discharged its duties and responsibilities hereunder and under the Basic
Documents to the extent the Administrator has agreed in the Administration
Agreement to perform any act or to discharge any duty of the Owner Trustee
hereunder or under any Basic Document, and the Owner Trustee shall not be held
liable for the default or failure of the Administrator to carry out its
obligations under the Administration Agreement.

         Section 6.03 Action upon Instruction. (a) Subject to Article IV and in
                      -----------------------
accordance with the terms of the Basic Documents, the Owners may by written
instruction direct the Owner Trustee in the management of the Trust. Such
direction may be exercised at any time by written instruction of the Owners
pursuant to Article IV.

         (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 under
any Basic Document, the Owner Trustee shall promptly give notice (in such form
as shall be appropriate under the circumstances) to the Owners requesting
instruction as to the course of action to be adopted, and to the extent the
Owner Trustee acts in good faith in accordance with any written instruction of
the Owners received, the Owner Trustee shall not be liable on account of such
action to any 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

                                      18
<PAGE>

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

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

         Section 6.04 No Duties Except as Specified in this Agreement or in
                      -----------------------------------------------------

------------
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 6.03; 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 Securities and Exchange Commission filing
for the Trust 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 that are not related to the ownership or the administration of the Owner
Trust Estate.

         Section 6.05 No Action Except Under Specified Documents or
                      ---------------------------------------------

------------
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
and (iii) in accordance with any document or instruction delivered to the Owner
Trustee pursuant to Section 6.03.

         Section 6.06 Restrictions. The Owner Trustee shall not take any action
                      ------------
(a) that is inconsistent with the purposes of the Trust set forth in Section

the Trust's becoming taxable as a corporation for

                                      19
<PAGE>

federal income tax purposes. The Owners shall not direct the Owner Trustee to
take action that would violate the provisions of this Section.

require the Owner Trustee to expend or risk funds or otherwise incur any

the Owners, unless such Owners have 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

Agent therein designated, (ii) the amount of any such final payment and (iii)
that the Record Date otherwise applicable to such Distribution Date is not
applicable, payments being made only upon presentation and surrender of the
Trust Certificates at the office of the Paying Agent therein specified. The
Owner Trustee shall give such notice to the Certificate Registrar (if other than
the Owner Trustee) and the Paying Agent at the time such notice is given to
Certificateholders. Upon presentation and surrender of the Trust Certificates,
the Paying Agent shall cause to be distributed to Certificateholders amounts
distributable on such Distribution Date pursuant to Section 5.02.

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

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

                      ------------------------------------------
that an Insolvency Event shall occur with respect to the Company, this Agreement
shall be terminated in accordance with Section 9.01 90 days after the date of
such Insolvency Event, unless, before the end of such 90-day period, the Owner
Trustee shall have received written instructions from Holders of Certificates
(other than the Company) representing more than 50% of the Certificate Balance
(not including the Certificate Balance of the Trust Certificates held by the
Company), to the effect that each such party disapproves of the liquidation of
the Mortgage Loans and of the Trust. Promptly

the Company shall give the Indenture Trustee and the Owner Trustee written
notice of such Insolvency Event, (B) the Owner Trustee shall, upon the receipt
of such written notice from the Company, give prompt written notice to the
Certificateholders and the Indenture Trustee, of the occurrence of such event
and (C) the Indenture Trustee shall, upon receipt of written notice of such
Insolvency Event from the Owner Trustee or the Company, give prompt written
notice to the Noteholders of the occurrence of such event; provided, however,
that any failure to give a notice required by this sentence shall not prevent or
delay, in any manner, a termination of the Trust pursuant to the first sentence
of this Section 9.02. Upon a termination pursuant to this Section, the Owner
Trustee shall direct the Indenture Trustee promptly to sell the assets of the
Trust (other than the Trust Accounts and the Certificate Distribution Account)

commercially reasonable terms. The proceeds of such a sale of the assets of the
Trust shall be treated as collections under the Sale and Servicing Agreement.

         Section 10.01 Eligibility Requirements for Owner Trustee. The Owner
                       ------------------------------------------
Trustee shall at all times be a corporation satisfying the provisions of Section
3807(a) of the Business Trust Statute; authorized to exercise corporate trust
powers; having a combined capital and surplus of at least $50,000,000 and
subject to supervision or examination by federal or state authorities; and
having (or having a parent that has) a rating of at least [____] by
[__________]. If such corporation shall publish reports of condition at least
annually pursuant to law or to the requirements of the aforesaid supervising or
examining authority, then for the purpose of this Section, the combined capital
and surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. In
case at any time the Owner Trustee shall cease to be eligible in accordance with
the provisions of this Section, the Owner Trustee shall resign immediately in
the manner and with the effect specified in Section 10.02.

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

         If at any time the Owner Trustee shall cease to be eligible in
accordance with the provisions of Section 10.01 and shall fail to resign after
written request therefor by the Administrator, or if at any time the Owner
Trustee shall be legally unable to act, or shall be adjudged bankrupt or
insolvent, or a receiver of the Owner Trustee or of its property shall be
appointed, or any public officer shall

                                      25
<PAGE>

take charge or control of the Owner Trustee or of its property or affairs for
the purpose of rehabilitation, conservation or liquidation, then the
Administrator may remove the Owner Trustee. If the Administrator shall remove
the Owner Trustee under the authority of the immediately preceding sentence, the
Administrator shall promptly appoint a successor Owner Trustee by written
instrument, in duplicate, one copy of which instrument shall be delivered to the
outgoing Owner Trustee so removed and one copy to the successor Owner Trustee,
and shall pay all fees owed to the outgoing Owner Trustee.

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

         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.

         Upon acceptance of appointment by a successor Owner Trustee pursuant to
this Section, the Administrator shall mail notice thereof to all
Certificateholders, the Indenture Trustee, the Noteholders and the Rating
Agencies. If the Administrator shall fail to mail such notice within 10 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

                                      26
<PAGE>

10.01 and, provided, further, that the Owner Trustee shall mail notice of such
merger or consolidation to the Rating Agencies.

         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 Owner 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 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 Administrator and the
Owner Trustee may consider necessary or desirable. If the Administrator shall
not have joined in such appointment within 15 days after the receipt by it of a
request so to do, the Owner Trustee alone shall have the power to make such
appointment. No co-trustee or separate trustee under this Agreement shall be
required to meet the terms of eligibility as a successor Owner Trustee pursuant
to Section 10.01 and no notice of the appointment of any co-trustee or separate
trustee shall be required pursuant to Section 10.03.

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

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

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

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

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

                                      27
<PAGE>

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

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

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

     Distributions on this Trust Certificate will be made as provided in the
Trust Agreement by the Owner Trustee by wire transfer or check mailed to the
Certificateholder of record in the Certificate Register without the presentation
or surrender of this Trust Certificate or the making of any notation hereon,
except that with respect to Trust Certificates registered on the Record Date in
the name of the nominee of the Clearing Agency (initially, such nominee to be
Cede & Co.), payments will be made by wire transfer in immediately available
funds to the account designated by such nominee. Except as otherwise provided in
the Trust Agreement and notwithstanding the above, the final distribution on
this Trust Certificate will be made after due notice by the Owner Trustee of the
pendency of such distribution and only upon presentation and surrender of this
Trust Certificate at the office or agency maintained for that purpose by the
Owner Trustee in the Borough of Manhattan, The City of New York.

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

an authorized officer of the Owner Trustee, by manual signature, this Trust
Certificate shall not entitle the Holder hereof to any benefit under the Trust
Agreement or the Sale and Servicing Agreement or be valid for any purpose.

                         [REVERSE OF TRUST CERTIFICATE]

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

     The Trust Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor and the Company and the rights of the Certificateholders under the
Trust Agreement at any time by the Depositor, the Company and the Owner Trustee
with the consent of the Holders of the Trust Certificates and the Notes, each
voting as a class, evidencing not less than a majority of the Certificate
Balance and the outstanding principal balance of the Notes of each such class.
Any such consent by the Holder of this Trust Certificate shall be conclusive and
binding on such Holder and on all future Holders of this Trust Certificate and
of any Trust Certificate issued upon the transfer hereof or in exchange herefor
or in lieu hereof, whether or not notation of such consent is made upon this
Trust Certificate. The Trust Agreement also permits the amendment thereof, in
certain limited circumstances, without the consent of the Holders of any of the
Trust Certificates.

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

     Except as provided in the Trust Agreement, the Trust Certificates are
issuable only as registered Trust Certificates without coupons in denominations
of $[__________] and in integral multiples of $[_______] in excess thereof. As
provided in the Trust Agreement and subject to certain limitations therein set
forth, Trust Certificates are exchangeable for new Trust Certificates of
authorized denominations evidencing the same aggregate denomination, as
requested by the Holder surrendering the same. No service charge will be made
for any such registration of transfer or

                                      A-5

exchange, but the Owner Trustee or the Certificate Registrar may require payment
of a sum sufficient to cover any tax or governmental charge payable in
connection therewith.

     The Owner Trustee, the Certificate Registrar and any agent of the Owner
Trustee or the Certificate Registrar 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 or any such agent shall be affected by
any notice to the contrary.

     The obligations and responsibilities created by the Trust Agreement and the
Trust created thereby shall terminate upon the payment to Certificateholders of
all amounts required to be paid to them pursuant to the Trust Agreement and the
Sale and Servicing Agreement and the disposition of all property held as part of
the Owner Trust Estate. The Master Servicer of the Mortgage Loans may at its
option purchase the Owner Trust Estate at a price specified in the Sale and
Servicing Agreement, and such purchase of the Mortgage Loans and other property
of the Trust will effect early retirement of the Trust Certificates; however,
such right of purchase is exercisable only as of the last day of any Collection
Period as of which the Pool Balance is less than or equal to [____]% of the
Original Pool Balance.

     The Trust Certificates may not be acquired by (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'). By accepting and holding this
Trust Certificate, the Holder hereof shall be deemed to have represented and
warranted that it is not a Benefit Plan.
