The Trust is hereby authorized to engage in the foregoing activities and shall

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. The Owner
Trustee hereby accepts its appointment subject to the terms and conditions
hereof.

                  SECTION 2.5 Initial Capital Contribution of Assets of the
Trust. Pursuant to the Organizational Trust Agreement, the Depositor transferred
to the Owner Trustee, as of the date hereof, the sum of $1.00. The Owner Trustee
hereby acknowledges receipt in trust from the Depositor, as of the date hereof,
of the foregoing contributions which shall constitute the initial assets of the
Trust and shall be deposited in the Certificate Distribution Account. 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.

                  SECTION 2.6 Declaration of Trust. The Owner Trustee hereby
declares that it shall hold the assets of the Trust in trust upon and subject to

created by the arrangements between the Trust, the Servicer and the Depositor is
intended to constitute the formation of a partnership. The sale by the Depositor
of Class [__] Certificates is

   4
intended to effect a termination of that partnership under Code Section 708 and
the creation of a new tax partnership (the "Tax Partnership") whose partners are
the Class[__] Certificateholders and the Class [__] Certificateholders. The Tax
Partnership shall be governed as set forth in the Tax Partnership Agreement
attached hereto as Annex A.

                  SECTION 2.7 Liability of the Depositor and the
Certificateholders.

                  (a) The Depositor shall be liable directly to and shall
indemnify an injured party for all losses, claims, damages, liabilities and
expenses of the Trust (including Expenses (as defined in Section 6.9(b)), to the
extent not paid out of the assets of the Trust) to the extent that the Depositor
would be liable if the Trust were a partnership under the Uniform Limited
Partnership Act in which the Depositor were a general partner; provided,
however, that the Depositor shall not be liable for (i) any losses incurred by a
Certificateholder or a Certificate Owner in its capacity as an investor in the
Certificates or by a Noteholder in its capacity as an investor in the Notes or
(ii) any losses, claims, damages, liabilities and expenses arising out of the
imposition by any taxing authority of any federal, state or local income or
franchise taxes or any other taxes imposed on or measured by gross or net
income, gross or net receipts, capital, net worth and similar items (including
any interest, penalties or additions with respect thereto) upon the
Certificateholders, the Certificate Owners, the Noteholders, the Owner Trustee
or the Indenture Trustee (including any liabilities, costs or expenses with
respect thereto) with respect to the Mortgage Loans not specifically indemnified
against or represented to hereunder. In addition, any third party creditors of
the Trust (other than in connection with the obligations described in the
preceding sentence for which the Depositors shall not be liable) shall be deemed
third party beneficiaries of this subsection 2.7(a). The obligations of the
Depositor under this subsection 2.7(a) shall be evidenced by the Class [__]
Certificates.

                  (b) No Certificate Owner or Certificateholder, other than to
the extent set forth in subsection 2.7(a) with respect to the Depositor, shall
have any personal liability for any liability or obligation of the Trust.

                  SECTION 2.8 Title to Trust Property. Legal title to all of the
assets of the Trust 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 assets of the Trust 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.

                  SECTION 2.9 Situs of Trust. The Trust shall 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. The Trust shall not have any employees in any state other
than Delaware; provided, however, that nothing herein shall restrict or prohibit
the Owner Trustee from having employees within or without the State of Delaware.
Payments shall 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 only
office of the Trust shall be the Corporate Trust Office in Delaware.

                  SECTION 2.10 Representations and Warranties of the Depositor.
The Depositor hereby represents and warrants to the Owner Trustee that:

                                       3

                                  ARTICLE III

                                THE CERTIFICATES

                  SECTION 3.1 Initial Certificate Ownership. Upon the formation
of the Trust by the contribution by the Depositor pursuant to Section 2.5, the
Depositor shall be the initial beneficiary of the Trust. Upon the execution and
the initial delivery of Certificates pursuant to Section 3.3 below, the
Depositor shall be the only Certificateholder.

                  SECTION 3.2 Form of the Certificates.

                  (a) The Class [__] Certificates and the Class [__] Certificate
shall be substantially in the form set forth in Exhibits A-1 and A-2,
respectively, and the Class [__] Certificates shall be issued in minimum
denominations of $1,000 and in integral multiples thereof. The Certificates
shall be executed on behalf of the Trust by manual or facsimile signature of an
authorized signatory of the Owner Trustee. Certificates bearing the manual or
facsimile signatures of individuals who were, at the time when such signatures
shall have been affixed, authorized to sign on behalf of the Trust, shall be
valid and binding obligations of the Trust, notwithstanding that such
individuals or any of them shall have ceased to be so authorized prior to the
authentication and delivery of such Certificates or did not hold such offices at
the date of authentication and delivery of such Certificates.

                  (b) The Definitive Certificates shall be typewritten, printed,
lithographed or engraved or produced by any combination of these methods (with
or without steel engraved borders) all as determined by the authorized signatory
of the Owner Trustee or the Owner Trustee's authenticating agent executing such
Certificates, as evidenced by their execution of such Certificates.

                  (c) The terms of the Certificates set forth in Exhibits A-1
and A-2 shall form part of this Agreement.

                  SECTION 3.3 Execution, Authentication and Delivery.
Concurrently with the transfer of the Mortgage Loans to the Trust pursuant to
the Pooling and Servicing Agreement, the Owner Trustee shall execute, or cause
its authenticating agent to execute, (i) the Class [__] Certificates in an
aggregate principal amount equal to the Original Class [__] Principal Balance
and (ii) one Class [__] Certificate, to be executed on behalf of the Trust,
authenticated and delivered to or upon the written order of the Depositor,
signed by a Responsible Officer of the Depositor, without further corporate
action by the Depositor, in Authorized Denominations. No Certificate shall
entitle its holder to any benefit under this Agreement, or shall be valid for
any purpose, unless there shall appear on such Certificate a certificate of
authentication substantially in the form set forth in Exhibits A-1 and A-2,
executed by the Owner Trustee or [______________], as the Owner Trustee's
authenticating agent, by manual signature. Such authentication shall constitute
conclusive evidence that such Certificate shall have been duly



                                       5
   7
authenticated and delivered hereunder. All Certificates shall be dated the date
of their authentication.

                  SECTION 3.4 Registration; Registration of Transfer and
Exchange of Certificates.

                  (a) The Certificate Registrar shall cause to be kept at its
office or agency in New York, New York, or at its designated agent, a
Certificate Register in which, subject to such reasonable regulations as it may
prescribe, it shall provide for the registration of Certificates and of
transfers and exchanges of Certificates as herein provided. Upon any resignation
of a Certificate Registrar, the Owner Trustee shall promptly appoint a successor
or, if it elects not to make such an appointment, assume the duties of the
Certificate Registrar. [_________________] shall be the initial Certificate
Registrar.

                  (b) The Class [___] Certificate has not been registered or
qualified under the Securities Act of 1933, as amended (the "1933 Act"), or any
state securities laws or "Blue Sky" laws. No transfer, sale, pledge or other
disposition of the Class [__] Certificate shall be made unless such disposition
is made pursuant to the proviso set forth in Section 3.10.

                  None of the Servicer, the Depositor, the Certificate Registrar
nor the Owner Trustee is obligated under this Agreement to register the Class
[__] Certificate under the 1933 Act or any other securities law or to take any
action not otherwise required under this Agreement to permit the transfer or
registration of transfer of the Class [__] Certificate without such registration
or qualification. Any Class [__] Certificateholder desiring to effect such
transfer shall, and does hereby agree to, promptly reimburse the Owner Trustee,
the Depositor, the Certificate Registrar and the Servicer for costs and expenses
incurred in connection with any liability that results if the transfer is not so
exempt or is not made in accordance with such applicable federal and state laws.

                  In addition to the restrictions set forth in Section 9.11,
none of the Trust, the Servicer, the Depositor, the Administrator or any Seller
shall be a Class [__] Certificateholder; provided, however, that the Depositor
may hold Class [__] Certificates upon receipt thereof until such Class [__]
Certificates are sold pursuant to the Underwriting Agreement. Any attempted or
purported transfer in violation of the preceding sentence shall be absolutely
null and void and shall vest no rights in the purported transferee. If any
purported transferee shall become a Holder of a Class [__]Certificate in
violation of such sentence, then the last preceding Holder shall be restored to
all rights as Holder thereof retroactive to the date of registration of transfer
of such Certificate. The Owner Trustee shall notify the Servicer of any transfer
in violation of this paragraph upon receipt of written notice thereof. None of
the Owner Trustee, the Certificate Registrar or any Paying Agent shall be liable
to any Person for any registration of transfer of a Class [__] Certificate not
permitted by this paragraph or for making any payments due on such Class [__]
Certificate to the Holder thereof or taking any other action with respect to
such Holder under the provisions of this Agreement so long as the transfer was
registered without such receipt. The Owner Trustee shall be entitled, but not
obligated, to recover from any Holder of a Class [__] Certificate that was in
fact not a permitted Holder under this paragraph, all payments made on such
Class [__] Certificate at and after such time. Any such payments so recovered by




                                       6
   8
the Owner Trustee shall be paid and delivered by the Owner Trustee to the last
preceding Holder of such Class [__] Certificate.

                  Subject to the preceding paragraphs, upon surrender for
registration of transfer of any Certificate at the office or agency of the Owner
Trustee maintained pursuant to Section 3.8, the Owner Trustee shall execute, and
the Owner Trustee or its authenticating agent shall authenticate and deliver in
the name of the designated transferee or transferees, a new Certificate of the
same Class and Percentage Interest and dated the date of authentication by the
Owner Trustee or such authenticating agent.

                  At the option of the Certificateholders, Certificates may be
exchanged for other Certificates of Authorized Denominations of a like aggregate
Percentage Interest, upon surrender of the Certificates to be exchanged at such
office. Whenever any Certificates are so surrendered for exchange, the Owner
Trustee or its Authenticating Agent shall execute, authenticate and deliver the
Certificates which the Certificateholder making the exchange is entitled to
receive.

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

                  All Certificates surrendered for registration of transfer or
exchange shall be marked "canceled" by the Owner Trustee.

                  SECTION 3.5 Mutilated; Destroyed; Lost or Stolen Certificates.

                  (a) If (i) any mutilated Certificate is surrendered to the
Certificate Registrar, or the Certificate Registrar receives evidence to its
satisfaction of the destruction, loss or theft of any Certificate, and (ii)
there is delivered to the Certificate Registrar, the Owner Trustee and the Trust
such security or indemnity as may be required by them to hold each of them
harmless, then, in the absence of notice to the Certificate Registrar or the
Owner Trustee that such Certificate has been acquired by a bona fide purchaser,
the Owner Trustee shall execute on behalf of the Trust and the Owner Trustee or
the Owner Trustee's Authenticating Agent shall authenticate and deliver, in
exchange for or in lieu of any such mutilated, destroyed, lost or stolen
Certificate, a replacement Certificate of a like class and aggregate principal
amount; provided, however, that if any such destroyed, lost or stolen
Certificate, but not a mutilated Certificate, shall have become or within seven
days shall be due and payable, then, instead of issuing a replacement
Certificate, the Owner Trustee may pay such destroyed, lost or stolen
Certificate when so due or payable.

                  (b) If, after the delivery of a replacement Certificate or
payment in respect of a destroyed, lost or stolen Certificate pursuant to
subsection 3.5(a), a bona fide purchaser of the original Certificate in lieu of
which such replacement Certificate was issued presents for payment such original
Certificate, the Owner Trustee shall be entitled to recover such replacement
Certificate (or such payment) from the Person to whom it was delivered or any
Person taking such replacement Certificate from such Person to whom such
replacement Certificate was delivered or any assignee of such Person, except a
bona fide purchaser, and shall



                                       7
   9
be entitled to recover upon the security or indemnity provided therefor to the
extent of any loss, damage, cost or expense incurred by the Owner Trustee in
connection therewith.

                  (c) In connection with the issuance of any replacement
Certificate under this Section 3.5, the Owner Trustee or the Certificate
Registrar may require the payment by the Holder of such Certificate of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
relation thereto and any other reasonable expenses (including the fees and
expenses of the Owner Trustee and the Certificate Registrar) connected
therewith.

                  (d) Any duplicate Certificate issued pursuant to this Section
3.5 in replacement of any mutilated, destroyed, lost or stolen Certificate shall
constitute an original additional contractual obligation of the Trust, whether
or not the mutilated, destroyed, lost or stolen Certificate shall be found at
any time or be enforced by anyone, and shall be entitled to all the benefits of
this Agreement equally and proportionately with any and all other Certificates
duly issued hereunder.

                  (e) The provisions of this Section 3.5 are exclusive and shall
preclude (to the extent lawful) all other rights and remedies with respect to
the replacement or payment of mutilated, destroyed, lost or stolen Certificates.

                  SECTION 3.6 Persons Deemed Certificateholders. Prior to due
presentation of a Certificate for registration of transfer, the Owner Trustee,
the Certificate Registrar or any Paying Agent may treat the Person in whose name
any Certificate shall be registered in the Certificate Register as the
Certificateholder of such Certificate for the purpose of receiving distributions
pursuant to Article V and for all other purposes whatsoever, and neither the
Owner Trustee nor the Certificate Registrar shall be affected by any notice to
the contrary.

                  SECTION 3.7 Access to List of Certificateholders' Names and
Addresses. The Certificate Registrar shall furnish or cause to be furnished to
the Credit Enhancer, the Servicer or the Depositor, within 15 days after receipt
by the Certificate Registrar of a request therefor from the Credit Enhancer, the
Servicer or the Depositor in writing, as the case may be, a list, in such form
as the Credit Enhancer, the Servicer or the Depositor may reasonably require, of
the names and addresses of the Certificateholders as of the most recent Record
Date. Each Holder, by receiving and holding a Certificate, shall be deemed to
have agreed not to hold any of the Credit Enhancer, the Servicer, the Depositor,
the Certificate Registrar or the Owner Trustee 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 For Surrenders. The Owner
Trustee shall maintain in the Borough of Manhattan, the City of New York, an
office or offices or agency or agencies where Certificates may be surrendered
for registration of transfer or exchange and where notices and demands to or
upon the Owner Trustee in respect of the Certificates and the Basic Documents
may be served. The Owner Trustee initially designates the offices of
[_______________],as its principal office for such purposes. The Owner Trustee
shall give prompt written notice to the Depositor and to the Certificateholders
of any change in the location of the Certificate Register or any such office or
agency.

                                       8
   10
                  SECTION 3.9 Appointment of Paying Agent. The Paying Agent
shall make distributions to Certificateholders from the Certificate Distribution
Account pursuant to Section 5.2 and shall report the amounts of such
distributions to the Owner Trustee and the Servicer. Any Paying Agent shall have
the revocable power to withdraw funds from the Certificate Distribution Account
for the purpose of making the distributions referred to above. The Owner Trustee
may revoke such power and remove the Paying Agent if the Owner Trustee
determines in its sole discretion that the Paying Agent shall have failed to
perform its obligations under this Agreement in any material respect. The Paying
Agent shall initially 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 and the Credit Enhancer. If [________________] shall no longer be
the Paying Agent, the Owner Trustee shall appoint a successor to act as Paying
Agent (which shall be a bank or trust company acceptable to the Credit Enhancer
and the Rating Agencies). The Owner Trustee shall cause such successor Paying
Agent or any additional Paying Agent appointed by the Owner Trustee to execute
and deliver to the Owner Trustee an instrument in which such successor Paying
Agent or additional Paying Agent shall agree with the Owner Trustee that as
Paying Agent, such successor Paying Agent or additional Paying Agent shall hold
all sums, if any, held by it for payment to the Certificateholders in trust for
the benefit of the Certificateholders entitled thereto until such sums shall be
paid to such Certificateholders. The Paying Agent shall return all unclaimed
funds to the Owner Trustee, and upon removal of a Paying Agent, such Paying
Agent shall also return all funds in its possession to the Owner Trustee. The
provisions of Article VI shall apply to the Owner Trustee also in its role as
Paying Agent, for so long as the Owner Trustee shall act as Paying Agent and, to
the extent applicable, to any other paying agent appointed hereunder. Any
reference in this Agreement to the Paying Agent shall include any co-paying
agent unless the context requires otherwise.

                  SECTION 3.10 Restriction on Transfers by Class [__]
Certificateholder. The Class [__] Certificateholder shall not sell, transfer,
assign or dispose of all or any portion of the Class [__] Certificate; provided,
that the Class [__] Certificateholder may, within ten Business Days of the
Closing Date, make a one-time transfer to a wholly-owned subsidiary of such
Class [__] Certificateholder; provided, that the Depositor shall retain at least
[two] percent of its original holdings in the Class [__] Certificate; and
provided, further, if the transferee is a wholly-owned subsidiary, the
transferee shall obtain no rights as a result of the transfer other than rights
to distributions and tax allocations. Upon completion of such transfer, the
Depositor shall certify to the Owner Trustee as to compliance with this Section
3.10.

                  SECTION 3.11 Book-Entry Certificates. The Class [__]
Certificates, upon original issuance, shall be issued in the form of a
typewritten Certificate or Certificates representing Book-Entry Certificates, to
be delivered to the Depository. Such Class [__] Certificate or Certificates
shall initially be registered on the Certificate Register in the name of Cede &
Co., the nominee of the initial Depository, and no Certificate Owner of a Class
[__] Certificate or Certificates shall receive a definitive Class [__]
Certificate representing such Certificate Owner's interest in such Class [__]
Certificate, except as provided in Section 3.13. Unless and until definitive
fully registered Class [__] Certificates (the "Definitive Certificates") shall
have been issued to Certificate Owners pursuant to Section 3.13:

                  (a) the provisions of this Section 3.11 shall be in full force
and effect;

                                       9
   11
                  (b) the Certificate Registrar and the Owner Trustee shall be
entitled to deal with the Depository for all purposes of this Agreement
(including the payment of principal of and interest on the Certificates and the
giving of instructions or directions hereunder) as the sole Holder of the Class
[__] Certificates, and shall have no obligation to the Certificate Owners with
respect thereto;

                  (c) to the extent that the provisions of this Section 3.11
conflict with any other provisions of this Agreement, the provisions of this
Section 3.11 shall control;

                  (d) the rights of the Certificate Owners with respect to the
Class [__] Certificate or Certificates shall be exercised only through the
Depository and shall be limited to those established by law and agreements
between such Certificate Owners and the Depository and/or the Depository
Participants. Pursuant to the Certificate Depository Agreement in the form
attached as Exhibit C, unless and until Definitive Certificates are issued
pursuant to Section 3.13, the initial Depository will make book-entry transfers
among the Depository Participants and receive and transmit payments of principal
of and interest on the Class [__] Certificates to such Depository Participants;

                  (e) whenever this Agreement requires or permits actions to be
taken based upon instructions or directions of Holders of Certificates
evidencing a specified aggregate Percentage Interest, the Depository shall be
deemed to represent such percentage only to the extent that it has received
instructions to such effect from Certificate Owners and/or Depository
Participants owning or representing, respectively, such required aggregate
Percentage Interest of Class [__] Certificates (taking into account the proviso
contained in the definition of "Certificateholder" contained in the Pooling and
Servicing Agreement) and has delivered such instructions to the Owner Trustee;
provided, however, that the provisions of this Section 3.11 shall not be
applicable in respect of Class [__] Certificates issued to the Depositor. The
Depositor or the Owner Trustee may set a record date for the purpose of
determining the identity of Holders of Class [__] Certificates entitled to vote
or to consent to any action by vote as provided in this Agreement.

                  SECTION 3.12 Notices to Depository. Whenever a notice or other
communication to the Class [__] Certificateholders is required under this
Agreement, the Indenture or the Pooling and Servicing Agreement, unless and
until Definitive Certificates shall have been issued to Certificate Owners
pursuant to Section 3.13, the Owner Trustee shall give all such notices and
communications specified herein to be given to Class [__] Certificateholders to
the Depository and shall have no further obligation to the Certificate Owners of
the Class [__] Certificates.

                  SECTION 3.13 Definitive Certificates. (a) The Class [__]
Certificate shall be issued in the form of Definitive Certificates and (b) with
respect to the Class [__] Certificates, if (i) the Administrator advises the
Owner Trustee in writing that the Depository is no longer willing or able to
properly discharge its responsibilities with respect to the Class [__]
Certificates, and the Administrator is unable to locate a qualified successor;
(ii) the Administrator at its option advises the Owner Trustee in writing that
it elects to terminate the book-entry system through the Depository; or (iii)
after the occurrence of a Servicer Default under the Pooling and Servicing
Agreement, a Majority in Voting Interest of the Class [__]



                                       10
   12
Certificates advise the Depository in writing that the continuation of a
book-entry system through the Depository is no longer in the best interest of
the Certificate Owners of the Class [__] Certificates, then the Depository shall
notify all Certificate Owners and the Owner Trustee of the occurrence of any
such event and of the availability of Definitive Certificates to Certificate
Owners requesting the same. Upon surrender to the Owner Trustee of the
typewritten Certificate or Certificates representing the Book-Entry Certificates
by the Depository, accompanied by registration instructions, the Owner Trustee
shall execute and authenticate the Definitive Certificates in accordance with
the instructions of the Depository. 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 Certificates, the Owner Trustee
shall recognize the Holders of the Definitive Certificates as
Certificateholders.

          SECTION 3.14 Appointment of Authenticating Agent. At any time when any
of the Certificates remain outstanding the Owner Trustee may appoint an
authenticating agent or agents with respect to the Certificates which shall be
authorized to act on behalf of the Owner Trustee to authenticate Certificates
issued upon original issuance, exchange or registration of transfer. The Owner
Trustee may revoke such power and remove any authenticating agent at any time.
Chemical Bank shall initially be an authenticating agent hereunder.

                  If any authenticating agent is appointed hereunder, the
Certificates may have endorsed thereon, in addition to the Trustee's certificate
of authentication, an alternate certificate of authentication in the following
form:

                  This is one of the Certificates referred to in the
within-mentioned Trust Agreement.

                  (a) The Owner Trustee undertakes to perform such duties, and
only such duties, as are specifically set forth in this Agreement and the other

the Certificateholders, subject to the Basic Documents and in accordance with
the provisions of this Agreement. No implied covenants or obligations shall be
read into this Agreement against the Owner Trustee.

                  (b) 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 liable for the default or failure of the Administrator to carry out its
obligations under the Administration Agreement.

                  (c) In the absence of bad faith on its part, the Owner Trustee
may conclusively rely upon certificates or opinions furnished to the Owner
Trustee and conforming to the requirements of this Agreement in determining the
truth of the statements and the correctness of the opinions contained therein;
provided, however, that the Owner Trustee shall have examined such certificates
or opinions so as to determine compliance of the same with the requirements of
this Agreement.

   17
                  (d) The Owner Trustee may not be relieved from liability for
its own negligent action, its own negligent failure to act or its own bad faith
or wilful misconduct, except that:

                  (i) this subsection 6.1(d) shall not limit the effect of
         subsection 6.1(a) or (b);

                  (ii) the Owner Trustee shall not be liable for any error of
         judgment made in good faith by a Responsible Officer unless it is

would, to the actual knowledge of a Responsible Officer of the Owner Trustee,
result in the Trust's becoming taxable as a corporation for federal, state or

perform its duties hereunder with respect to such trusts but only upon the terms
of this Agreement. The Owner Trustee also agrees to disburse all moneys actually
received by it constituting part of the assets of the Trust upon the terms of
the Basic Documents and this Agreement. The Owner Trustee shall not be liable or
accountable hereunder or under any Basic Document under any circumstances,
except (i) for its own negligent action, its own negligent failure to act or its

action taken or omitted to be taken by it in accordance with the instructions of
the Administrator, the Credit Enhancer or 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

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;

the Basic Documents, the Underwriting Agreement, the Notes, the Certificates
(other than the certificate of authentication on the Certificates) or of any
Mortgage Loans or any related documents, and the Owner Trustee shall in no event
assume or incur any liability, duty or obligation to any Noteholder or to any
Certificateholder, other than as expressly provided for herein and in the Basic

the Basic Documents or otherwise and the Owner Trustee shall have no obligation
or liability to perform the obligations of the Trust under this Agreement or the
Basic Documents that are required to be performed by the Administrator under the
Administration Agreement, the Indenture Trustee under the Indenture, the
Custodian under the Custodial Agreement or the Servicer under the Pooling and
Servicing Agreement;

                  (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, the Underwriting Agreement or any Basic Document, at
the request, order or direction of any of the Credit Enhancer or any of the
Certificateholders, unless the Credit Enhancer or such Certificateholders 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 be answerable for other than its
negligence or willful misconduct in the performance of any such act;

                  (h) 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, execute or file any Securities and
Exchange Commission filing or tax return for the Trust or to record this
Agreement or any Basic Document.

                  SECTION 6.4 Action upon Instruction by Certificateholders.

                  (a) Subject to Section 4.4, the Certificateholders 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
Certificateholders pursuant to Section 4.5.

                  (b) Notwithstanding the foregoing, 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, or is unsure as to the application, intent,
interpretation or meaning of any provision of this Agreement or the Basic
Documents, the Owner Trustee shall promptly give notice (in such form as shall
be appropriate under the circumstances) to the Credit Enhancer and the
Certificateholders 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 such instruction 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 instructions 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 which is consistent, in its view, with this
Agreement or the Basic Documents, and as it shall



                                       18
   20
deem to be in the best interests of the Certificateholders, and the Owner
Trustee shall have no liability to any Person for any such action or inaction.

                  SECTION 6.5 Furnishing of Documents. The Owner Trustee shall
furnish (a) to the Certificateholders, promptly upon receipt of a written
request therefor, duplicates or copies of all reports, notices, requests,
demands, certificates, financial statements and any other instruments furnished
to the Owner Trustee under the Basic Documents, and (b) to the Credit Enhancer,
copies of any reports, notices, requests, demands, certificates, financial
statements, and any other instruments relating to the Trust, the Certificates or
the Notes in the possession of the Owner Trustee, that the Credit Enhancer shall
request in writing.

                  SECTION 6.6 Representations and Warranties of Owner Trustee.
The Owner Trustee hereby represents and warrants to the Depositor, for the
benefit of the Certificateholders and the Credit Enhancer, that:

                  (a) It is a [banking corporation] duly organized, validly
existing and in good standing under the laws of the state of its incorporation.

                  (b) It has full power, authority and legal right to execute,
deliver and perform its obligations under this Agreement, and has taken all
necessary action to authorize the execution, delivery and performance by it of
this Agreement.

                  (c) The execution, delivery and performance by it of this
Agreement (i) shall not violate any provision of any law or regulation governing
the banking and trust powers of the Owner Trustee or any order, writ, judgment
or decree of any court, arbitrator or governmental authority applicable to the
Owner Trustee or any of its assets, (ii) shall not violate any provision of the
corporate charter or by-laws of the Owner Trustee, or (iii) shall not violate
any provision of, or constitute, with or without notice or lapse of time, a
default under, or result in the creation or imposition of any lien on any
properties included in the Trust pursuant to the provisions of any mortgage,
indenture, contract, agreement or other undertaking to which it is a party,
which violation, default or lien could reasonably be expected to have a
materially adverse effect on the Owner Trustee's performance or ability to
perform its duties as Owner Trustee under this Agreement or on the transactions
contemplated in this Agreement.

                  (d) This Agreement has been duly executed and delivered by the
Owner Trustee and constitutes the legal, valid and binding agreement of the
Owner Trustee, enforceable in accordance with its terms, except as
enforceability may be limited by bankruptcy, insolvency, reorganization, or
other similar laws affecting the enforcement of creditors' rights in general and
by general principles of equity, regardless of whether such enforceability is
considered in a proceeding in equity or at law.

                  SECTION 6.7 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 believed by it to be signed by the proper party or parties
and need not investigate any fact or matter in any such document. The Owner
Trustee may accept a certified copy of a resolution of the board of directors or
other



                                       19
   21
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 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,
attorneys, custodians or nominees (including the granting of a power of attorney
(x) to officers of [_________________] to execute and deliver any Basic
Document, Certificate, Note or other documents related thereto on behalf of the
Owner Trustee or (y) to the Administrator to execute any tax return of the Trust
or any document, report or other instrument to be filed with the Securities and
Exchange Commission or any state securities commission or administration)
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, attorneys,
custodians or nominees if such agents, attorneys, custodians or nominees shall
have been selected by the Owner Trustee with reasonable care and (ii) may
consult with counsel, accountants and other skilled professionals 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 opinion or advice of any such counsel, accountants or other such Persons.

                  SECTION 6.8 Owner Trustee May Own Certificates and Notes. The
Owner Trustee in its individual or any other capacity may become the owner or
pledgee of Certificates or Notes and may deal with either Depositor, the
Administrator, the Custodian, the Indenture Trustee and the Servicer in
transactions in the same manner and with the same rights as it would have if it
were not the Owner Trustee.

                  SECTION 6.9 Compensation and Indemnity. (a) The Owner Trustee
shall receive from the Depositor as compensation for its services hereunder such
fees as have been separately agreed upon before the date hereof between the
Depositor and the Owner Trustee, and the Owner Trustee 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, custodians, nominees, representatives, experts and counsel as the Owner
Trustee may employ in connection with the exercise and performance of its rights
and its duties hereunder. The Servicer shall indemnify the Owner Trustee and its
successors, assigns, agents and servants in accordance with the provisions of
Section 8.01 of the Pooling and Servicing Agreement.

                  (a) The Depositor shall be liable as primary obligor for, and
shall indemnify the Owner Trustee and its 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 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


                                       20
   22
Basic Documents, the assets of the Trust, the administration of the Trust or the
action or inaction of the Owner Trustee hereunder, except only that the
Depositor shall not be liable for or required to indemnify the Owner Trustee
from and against Expenses arising or resulting from the negligence or willful
misconduct of the Owner Trustee. The indemnities contained in this Section 6.9
shall survive the resignation of the Owner Trustee, termination of the Trust or
the termination of this Agreement. Any amounts paid to the Owner Trustee
pursuant to this Article VI shall be deemed not to be a part of the assets of
the Trust immediately after such payment.

                  SECTION 6.10 Replacement of Owner Trustee.

                  (a) The Owner Trustee may resign at any time and be discharged
from the trusts hereby created by giving 30 days' prior written notice thereof
to the Credit Enhancer and the Administrator. The Administrator shall appoint a
successor Owner Trustee with the consent of the Credit Enhancer by delivering a
written instrument, in duplicate, to the resigning Owner Trustee and the
successor Owner Trustee. If no successor Owner Trustee shall have been 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. The Administrator
shall remove the Owner Trustee if:

                  (i) the Owner Trustee shall cease to be eligible in accordance
         with the provisions of Section 6.13 and shall fail to resign after
         written request therefor by the Administrator;

                  (ii) the Owner Trustee shall be adjudged bankrupt or
         insolvent;

                  (iii) a receiver or other public officer shall be appointed or
         take charge or control of the Owner Trustee or of its property or
         affairs for the purpose of rehabilitation, conservation or liquidation;
         or

                  (iv) the Owner Trustee shall otherwise be legally incapable of
         acting.

                  (b) If the Owner Trustee resigns or is removed or if a vacancy
exists in the office of Owner Trustee for any reason the Administrator shall
promptly appoint a successor Owner Trustee, with the consent of the Credit
Enhancer, 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 and other amounts owed to the
outgoing Owner Trustee.

                  (c) Any resignation or removal of the Owner Trustee and
appointment of a successor Owner Trustee pursuant to any of the provisions of
this Section 6.10 shall not become effective until a written acceptance of
appointment is delivered by the successor Owner Trustee to the outgoing Owner
Trustee and the Administrator and all fees and expenses due to the outgoing
Owner Trustee are paid. Any successor Owner Trustee appointed pursuant to this
Section 6.10 shall be eligible to act in such capacity in accordance with
Section 6.13 and, following compliance with the preceding sentence, shall become
fully vested with all the rights, powers, duties and obligations of its
predecessor under this Agreement, with like effect as if



                                       21
   23
originally named as Owner Trustee. The Administrator shall provide notice of
such resignation or removal of the Owner Trustee to the Credit Enhancer and each
of the Rating Agencies.

                  (d) 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. 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.

                  (e) Upon acceptance of appointment by a successor Owner
Trustee pursuant to this Section 6.10, the Administrator (or if the
Administrator fails to so notify, the successor Owner Trustee, at the expense of
the Administrator) shall mail notice of the successor of such Owner Trustee to
all Certificateholders, the Indenture Trustee, the Noteholders, the Credit
Enhancer and each of the Rating Agencies.

                  SECTION 6.11 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 6.13,
and without the execution or filing of any instrument or any further act on the
part of any of the parties hereto; provided, however, that the Owner Trustee
shall mail notice of such merger or consolidation to the Credit Enhancer and
each of the Rating Agencies.

                  SECTION 6.12 Appointment of Co-Trustee or Separate Trustee.

                  (a) Notwithstanding any other provisions of this Agreement, at
any time, for the purpose of meeting any legal requirement of any jurisdiction
in which any part of the assets of the Trust or any Mortgaged Property may at
the time be located, the Administrator and the Owner Trustee (with the consent
of the Credit Enhancer) 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 Credit Enhancer to act as co-trustee, jointly with the Owner
Trustee, or as separate trustee or trustees, of all or any part of the assets of
the Trust, 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
6.12, 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 (with the consent of the Credit
Enhancer) 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 6.13 and no notice of the
appointment of any co-trustee or separate trustee shall be required pursuant to
Section 6.10.

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

                                       22
   24
                  (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 Administrator and the Owner Trustee acting jointly
         may at any time accept the resignation of or remove any separate
         trustee or co-trustee; provided, however, that if the Administrator is
         in default under the Administration Agreement, the Owner Trustee acting
         alone may accept the resignation of or remove any separate trustee or
         co-trustee.

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

                  (d) 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 trustee.

          SECTION 6.13 Eligibility Requirements for Owner Trustee. The Owner
Trustee shall at all times: (a) be a corporation satisfying the provisions of
Section 3807(a) of the Business Trust Statute; (b) be authorized to exercise
corporate trust powers; (c) have a combined capital and surplus of at least
$50,000,000 and be subject to supervision or examination by federal or state
authorities; (d) have (or have a parent which has) a long-term unsecured debt
rating of at least [BBB] by [Standard & Poor's Corporation] and at least [Baa2]
by the [Moody's Investors Service, Inc.]; and (e) be acceptable to the Credit
Enhancer. If such corporation shall publish reports of condition at least
annually, pursuant to law or to the requirements of the



                                       23
   25
aforesaid supervising or examining authority, then for the purpose of this
Section 6.13, 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. If at any time the Owner Trustee shall cease
to be eligible in accordance with the provisions of this Section 6.13, the Owner
Trustee shall resign immediately in the manner and with the effect specified in
Section 6.10.

                  SECTION 6.14 Underwriting Agreement. For purposes of this
Article VI, the term "Basic Document" shall be deemed to include the
Underwriting Agreement.


                                  ARTICLE VII

                         TERMINATION OF TRUST AGREEMENT

                  SECTION 7.1 Termination of Trust Agreement.

                  (a) This Agreement (other than Article VI) and the Trust shall
terminate and be of no further force or effect on the earlier of: (i) the final
distribution by the Owner Trustee of all moneys or other property or proceeds of
the assets of the Trust in accordance with the terms of the Indenture, the
Pooling and Servicing Agreement (including the exercise of the Class [__]
Certificateholder of its option to purchase the Mortgage Loans pursuant to
Section 10.01 of the Pooling and Servicing Agreement) and Article V, (ii) at the
time provided in Section 7.2 or (iii) the expiration of 21 years from the death
of the last survivor of Joseph P. Kennedy, former Ambassador to the Court of St.
James, living on the date of this Trust Agreement. The bankruptcy, liquidation,
dissolution, death or incapacity of any Certificateholder, other than the
Depositor as described in Section 7.2, shall not (x) operate to terminate this
Agreement or the Trust, nor (y) entitle such 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 the assets of the Trust or (z) otherwise affect the rights, obligations
and liabilities of the parties hereto.

                  (b) Except as provided in Section 7.1(a), neither the
Depositor nor any Certificateholder shall be entitled to revoke or terminate the
Trust.

                  (c) Notice of any termination of the Trust, specifying the
Payment Date upon which the Certificateholders shall surrender their
Certificates to the Paying Agent for payment of the final distribution and
cancellation, shall be given by the Owner Trustee by letter to the Credit
Enhancer and the Certificateholders mailed within five Business Days of receipt
of notice of such termination from the Servicer given pursuant to subsection
10.01 of the Pooling and Servicing Agreement, stating: (i) the Payment Date upon
or with respect to which final payment of the Certificates shall be made upon
presentation and surrender of the Certificates at the office of the Paying Agent
therein designated; (ii) the amount of any such final payment; and (iii) that
the Record Date otherwise applicable to such Payment Date is not applicable,
payments being made only upon presentation and surrender of the 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



                                       24
   26
Certificateholders. Upon presentation and surrender of the Certificates, the
Paying Agent shall cause to be distributed to Certificateholders amounts
distributable on such Payment Date pursuant to Section 5.2.

                  (d) If all of the Certificateholders shall not surrender their
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 Certificates for
cancellation and receive the final distribution with respect thereto. If within
one year after the second notice all the 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 Certificates, and the cost
thereof shall be paid out of the funds and other assets that shall remain
subject to this Agreement. Subject to applicable laws with respect to escheat of
funds, any funds remaining in the Trust after exhaustion of such remedies in the
preceding sentence shall be deemed property of the Depositor and distributed by
the Owner Trustee to the Depositor.

                  (e) Each Certificateholder is required, and hereby agrees, to
return to the Owner Trustee, any Certificate with respect to which the Owner
Trustee has made the final distribution due thereon. Any such Certificate as to
which the Owner Trustee has made the final distribution thereon shall be deemed
canceled and shall no longer be outstanding for any purpose of this Agreement,
whether or not such Certificate is ever returned to the Owner Trustee.

                  (f) 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.

          SECTION 7.2 Dissolution upon Bankruptcy of the Depositor. This
Agreement shall be terminated in accordance with Section 7.1 90 days after the
occurrence of an Insolvency Event with respect to the Depositor, unless, before
the end of such 90 day period, the Owner Trustee shall have received written
instructions from (a) each of the Certificateholders (other than the Depositor)
and (b) each of the Noteholders, to the effect that each such party disapproves
of the liquidation of the Mortgage Loans and termination of the Trust. Promptly
after the occurrence of any Insolvency Event with respect to either Depositor:
(i) the Depositor shall give the Credit Enhancer, the Indenture Trustee, the
Rating Agencies and the Owner Trustee written notice of such Insolvency Event;
(ii) the Owner Trustee shall, upon the receipt of such written notice from the
Depositor, give prompt written notice to the Certificateholders and the
Indenture Trustee of the occurrence of such event and (iii) the Indenture
Trustee shall, upon receipt of written notice of such Insolvency Event from the
Owner Trustee or the Depositor, give prompt written notice to the Noteholders of
the occurrence of such event pursuant to Section 6.12 of the Indenture;
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 7.2. Upon a termination pursuant to this
Section 7.2, the Owner Trustee shall direct the Indenture Trustee promptly to
sell the assets of the Trust (other than the Accounts and the Certificate
Distribution Account) in a commercially reasonable manner and on commercially
reasonable terms. The proceeds of any such sale, disposition or liquidation of
the assets of the Trust shall be treated as collections on the Mortgage Loans
and deposited in the



                                       25
   27
Principal and Interest Account pursuant to Section [___] of the Pooling and
Servicing Agreement.


                                  ARTICLE VIII

                                   AMENDMENTS

          SECTION 8.1 Amendments Without Consent of Certificateholders or
Noteholders. This Agreement may be amended by the Depositor and the Owner
Trustee without the consent of any of the Noteholders or the Certificateholders
(but with the prior written consent of the Credit Enhancer and prior notice to
each of the Rating Agencies and the Administrator), to (i) cure any ambiguity,
(ii) correct or supplement any provision in this Agreement that may be defective
or inconsistent with any other provision in this Agreement, (iii) add or
supplement any credit enhancement for the benefit of the Noteholders or the
Certificateholders (provided that if any such addition shall affect any class of
Certificateholders differently than any other class of Certificateholders, then
such addition shall not, as evidenced by an Opinion of Counsel, adversely affect
in any material respect the interests of any class of Certificateholders), (iv)
add to the covenants, restrictions or obligations of the Depositor or the Owner
Trustee, (v) evidence and provide for the acceptance of the appointment of a
successor trustee with respect to the assets of the Trust and add to or change
any provisions as shall be necessary to facilitate the administration of the

the "Trust Agreement"), among the Depositor and [_________________________], 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 one of the duly authorized Certificates
designated as "Banc One HELOC Asset Backed Certificates Series 199[__]-[__],

[__] Certificates", and together with the Class [__] Certificates, the
"Certificates"). This Certificate is issued under and is subject to the terms,
provisions and conditions of the Trust Agreement, to which Trust Agreement the

which such holder is bound. Concurrently with the issuance of the Certificates,
the Issuer is issuing its [___]% Banc One HELOC Asset Backed Notes, Series

holders of the Certificates are subordinated to the rights of the holders of the

forth in the Pooling and Servicing Agreement and the Indenture.

                  Under the Trust Agreement, there shall be distributed on the

registered at the close of business on the Record Date (as defined below), such
Class [__] Certificateholder's Percentage Interest in the Class [__] Remittance
Amount to be distributed to Class [__] Certificateholders on such Payment Date;
provided, however, Class [__] Certificateholders shall not receive payments in
respect of the Class [__] Certificates if an Event of Default exists under the
Indenture. The "Record Date", with respect to any Payment Date, means the close
of business on the calendar day immediately preceding such Payment Date, or if
Definitive Certificates are issued, the last day of the calendar month preceding
the month in which the Payment Date occurs.

                  The distributions in respect of the Class [__] Remittance
Amount on this Certificate are payable in such coin or currency of the United
States of America as at the time of payment is legal tender for payment of

                  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 and to the extent described in
the Pooling and Servicing Agreement and the Indenture.

                  Each Certificateholder or Certificate Owner, by its acceptance
of a Class [__] Certificate or, in the case of a Certificate Owner, a beneficial
interest in a Class [__] Certificate, covenants and agrees that such
Certificateholder or Certificate Owner, as the case may be, shall not, prior to
the date which is one year and one day after the termination of the Trust
Agreement, acquiesce, petition or otherwise invoke or cause the Depositor or the
Trust to invoke the process of any court or governmental authority for the
purpose of commencing or sustaining a case against the Depositor or the Trust
under any federal or state bankruptcy, insolvency, reorganization or similar law
or appointing a receiver, liquidator, assignee, trustee, custodian, sequestrator
or other similar official of the Depositor or the Trust or any substantial part
of its property, or ordering the winding up or liquidation of the affairs of the
Depositor or the Trust.

the Trust Agreement by the Owner Trustee by wire transfer (as permitted by the
Trust Agreement) or check mailed to the Certificateholder of record in the

registered on the Record Date in the name of the nominee of the Depository

transfer in immediately available funds to the account designated by such

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
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 signatory of the Owner Trustee by manual
signature, this Certificate shall not entitle the holder hereof to any benefit
under the Trust Agreement or the Pooling 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

                  The Certificates do not represent an obligation, or an
interest in, the Depositor, the Servicer, any Seller, the Indenture Trustee, 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 or in 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 and
recoveries with respect to the Mortgage Loans and amounts withdrawable from the
Spread Account (and certain other amounts), all as more specifically set forth
herein and in the Trust Agreement and the Pooling and Servicing Agreement. A
copy of each of the Pooling and Servicing Agreement and the Trust Agreement may
be examined during normal business hours at the principal office of the
Administrator, and at such other places, if any, designated by the

                  [_________________________] has issued a guaranty surety bond
with respect to the Notes and the Class [__] Certificates, a copy of which is
attached as Exhibit I to the Pooling and Servicing Agreement. Pursuant to the
Pooling and Servicing Agreement and the Trust Agreement, the Class [__]
Certificateholder has pledged all of its right, title and interest in the Spread
Account to the Indenture Trustee to secure the Trust's payment obligations under
the Pooling and Servicing Agreement and the Indenture.

                  As provided in the Pooling and Servicing Agreement, deposits
and withdrawals from the Principal and Interest Account, the Collection Account,
the Spread Account, the Letter of Credit Fee Account and the Insurance Account
may be made by the Indenture Trustee from time to time for purposes other than
distributions to Noteholders and Certificateholders, such purposes including
reimbursement of certain expenses incurred by the Servicer and investment in
Permitted Investments.

                  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 Certificateholders under the
Trust Agreement at any time by the Depositor and the Owner Trustee with the
consent of the Credit Enhancer and the Majority in Voting Interest of
Outstanding Notes and the Majority in Voting Interest of Class [__]
Certificates. 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 registration of transfer
hereof or in exchange herefor 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 circumstances, without the consent of the Holders
of any of the Certificates or the Notes.

                  It is the intent of the Depositor, the Servicer, their
Affiliates, the Noteholders and the Certificateholders to treat the Trust as a
partnership with the assets of the partnership being the assets held by the
Trust, the partners of the partnership being the Class [__] Certificateholders
and the Class [__]Certificateholder and the Notes being the debt of the
partnership, in each case for purposes of Federal and state income tax,
franchise tax, and any other tax measured in whole or in part by income. Except
as otherwise required by appropriate taxing authorities, the Depositor, the
Servicer, their Affiliates, the Noteholders, and the



                                     A-1-7
   40
Certificateholders by acceptance of a Certificate, agree to treat, and to take
no action inconsistent with the treatment of, the Certificates for tax purposes
as interests in such partnership.

                  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 City of New York, accompanied by (i) 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 (ii) if requested by the Depositor, the
Undertaking Letter required by Section 9.11 of the Trust Agreement, and
thereupon one or more new 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 [_______________________].

                  The Class [__] Certificates are issuable only as registered
Certificates without coupons in denominations of $1,000 and in integral
multiples thereof. As provided in the Trust Agreement and subject to certain
limitations therein set forth, Class [__] Certificates are exchangeable for new
Class [__] Certificates of authorized denominations evidencing the same
aggregate denomination, as requested by the Holder surrendering the same;
provided, however, that no Class [__] Certificate may be subdivided such that
the denomination of any resulting Class [__] Certificate is less than $1,000. No
service charge shall be made for any such registration of transfer or exchange,
but the Owner Trustee or the Certificate Registrar may require payment of a sum
sufficient to cover any tax or governmental charge payable in connection
therewith.

                  The Owner Trustee, the Certificate Registrar 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 Pooling and Servicing Agreement and the disposition of
all property held as part of the Trust. The Class [__] Certificateholder may at
its option cause the Mortgage Loans and REO Properties to be sold at a minimum
price specified in the Pooling and Servicing Agreement, and the proceeds of such
sale of the Mortgage Loans and REO Property shall effect early retirement of the
Certificates; provided, however, that such right of purchase is exercisable only
following the Payment Date as of which the Pool Principal Balance is 10% or less
of the Original Pool Principal Balance.

                  Unless the certificate of authentication hereon has been
executed by the Owner Trustee by manual signature, this Certificate shall not be
entitled to any benefit under the Trust Agreement or be valid for any purpose.
