          Interest shall also be liable directly to and will indemnify the

          expenses of the Trust (including Expenses, to the extent not paid out
          of the Owner Trust Estate) to the extent that the holder of the GP

          Delaware Revised Uniform Limited Partnership Act in which the holder
          of the GP Interest were a general partner; provided, however, that the
          holder of the GP Interest shall not be liable for any losses incurred

          for which the holder of the GP Interest shall not be liable) shall be
          deemed third party beneficiaries of this paragraph. The obligations of
          the holder of the GP Interest under this paragraph shall be evidenced
          by the Trust Certificates described in Section 3.12, which for
          purposes of the Business Trust Statute shall be deemed to be a
          separate class of Trust Certificates from all other Trust Certificates
          issued by the Trust.

               (b) No Owner, other than to the extent set forth in clause (a),

          the Trust.

          SECTION 2.8. TITLE TO TRUST PROPERTY. Legal title to all the Owner
Trust Estate shall be vested at all times in the Trust as a separate legal
entity except where applicable law in any jurisdiction requires title to any
part of the Owner Trust Estate to be vested in a trustee or trustees, in which
case title shall be deemed to be vested in the Owner Trustee, a co-trustee
and/or a separate trustee, as the case may be.

          SECTION 2.9. SITUS OF TRUST. The Trust will be located and
administered in the State of ________________. All bank accounts maintained by

          properties.

               (e) It has been duly capitalized by the delivery of a demand note
          (the "Demand Note") from the Seller in the amount of $__________,
          which Demand Note has not been canceled, waived or terminated. The
          proceeds of such Demand Note have not been used and will not be used
          to pay (i) any of the expenses of the holder of the GP Interest in
          connection with the transactions contemplated by the Basic Documents
          or (ii) the purchase price for the Certificates purchased pursuant to
          Section 2.7. Such Demand Note is enforceable against the Seller,
          subject to its terms, and subject to applicable bankruptcy,
          insolvency, moratorium, fraudulent conveyance, reorganization and
          similar laws now or hereafter in effect relating to creditors' rights
          generally or the rights of creditors of banks the deposit accounts of
          which are insured by the Federal Deposit Insurance Corporation and
          subject to general principles of equity (whether applied in a
          proceeding at law or in equity).

          SECTION 2.12. FEDERAL INCOME TAX ALLOCATIONS. Net income of the Trust
for any month as determined for Federal income tax purposes (and each item of
income, gain, loss, credit and deduction entering into the computation thereof)
shall be allocated:

               (a) to the extent of available net income, among the
          Certificateholders as of the first Record Date following the end of
          such month, in proportion to their ownership of principal amount of
          Trust Certificates on such date, an amount of net income up to the sum
          of (i) the Certificateholders' Monthly Interest Distributable Amount
          for such month, (ii) interest on the excess, if any, of the
          Certificateholders' Interest Distributable Amount for the preceding
          Distribution Date over the amount in respect of interest at the
          Certificate Rate that is actually deposited in the Certificate
          Distribution Account on such preceding Distribution Date, to the
          extent permitted by law, at the Certificate Rate from such preceding
          Distribution Date through the current Distribution Date, and (iii) the
          portion of the market discount on the Mortgage Loans accrued during
          such month that is allocable to the excess of the initial aggregate
          principal amount of the Trust Certificates over their initial
          aggregate issue price; and

               (b) to the holder of the GP Interest, to the extent of any
          remaining net income.

If the net income of the Trust for any month is insufficient for the allocations
described in clause (a) above, subsequent net income shall first be allocated to
make up such shortfall before being allocated as provided in clause (b). Net
losses of the Trust, if any, for any month as determined for Federal income tax
purposes (and each item of income, gain, loss, credit and deduction entering
into the computation thereof) shall be allocated to the holder of the GP
Interest to the extent the holder of the GP Interest is reasonably expected as
determined by the Master Servicer to bear the economic burden of such net
losses, then net losses shall be allocated among the Certificateholders as of
the first Record Date following the end of such month in proportion to their
ownership of principal amount of Trust Certificates on such Record Date until
the principal balance of the Trust Certificates is reduced to zero. The holder
of the GP Interest is authorized to modify the allocations in this paragraph if
necessary or appropriate, in its sole discretion, for the allocations to fairly
reflect the economic income, gain or loss to the holder of the GP Interest, the
Certificateholders, or as otherwise required by the Code.

                                   ARTICLE III

                  Trust Certificates and Transfer of Interests

          SECTION 3.1. INITIAL OWNERSHIP. Upon the formation of the Trust by the
contribution by the Seller pursuant to Section 2.5 and until the issuance of the
Trust Certificates, the Seller shall be the sole beneficiary of the Trust.

          SECTION 3.2. THE TRUST CERTIFICATES. The Trust Certificates shall be
issued in denominations of $1,000 and integral multiples thereof; provided,
however, that (a) Trust Certificates may be issued to the holder of the GP
Interest pursuant to Section 2.7 in such denominations as to represent at least
1% of the initial Certificate Balance and (b) one Trust Certificate may be
issued in a denomination other than an integral multiple of $1,000. The Trust
Certificates shall be executed on behalf of the Trust by manual or facsimile
signature of an authorized officer of the Owner Trustee. Trust 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 validly issued and entitled to the benefit of this
Agreement, notwithstanding that such individuals or any of them shall have
ceased to be so authorized prior to the authentication and delivery of such
Trust Certificates or did not hold such offices at the date of authentication
and delivery of such Trust Certificates. A transferee of a Trust Certificate
shall become a Certificateholder, and shall be entitled to the rights and
subject to the obligations of a Certificateholder hereunder, upon due
registration of such Trust Certificate in such transferee's name pursuant to
Section 3.4.

          SECTION 3.3. AUTHENTICATION OF TRUST CERTIFICATES. Concurrently with
the initial sale of the Mortgage Loans to the Trust pursuant to the Master
Servicing Agreement, the Owner Trustee shall cause the Trust Certificates in an
aggregate principal amount equal to the initial Certificate Balance to be
executed on behalf of the Trust, authenticated and delivered to or upon the
written order of the Seller, signed by its chairman of the board, its president
or any vice president, without further corporate action by the Seller, in
authorized denominations. No Trust Certificate shall entitle its holder to any
benefit under this Agreement, or shall 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 authenticated and delivered hereunder.
All Trust Certificates shall be dated the date of their authentication.

          SECTION 3.4. REGISTRATION OF TRANSFER AND EXCHANGE OF TRUST
CERTIFICATES. The Certificate Registrar shall keep or cause to be kept, at the
office or agency maintained pursuant to Section 3.8, a Certificate Register in
which, subject to such reasonable regulations as it may prescribe, the Owner
Trustee shall provide for the registration of Trust Certificates and of
transfers and exchanges of Trust Certificates as herein provided. The Owner
Trustee shall be the initial Certificate Registrar.

          Upon surrender for registration of transfer of any Trust Certificate
at the office or agency maintained pursuant to Section 3.8, the Owner Trustee
shall execute, authenticate and deliver (or shall cause ____________, as its
authenticating agent, to authenticate and deliver), in the name of the
designated transferee or transferees, one or more new Trust Certificates in
authorized denominations of a like class and aggregate face amount dated the
date of authentication by the Owner Trustee or any authenticating agent. At the
option of a Holder, Trust Certificates may be exchanged for other Trust
Certificates of the same class in authorized denominations of a like aggregate
amount upon surrender of the Trust Certificates to be exchanged at the office or
agency maintained pursuant to Section 3.8.

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

          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.

          SECTION 3.5. MUTILATED, DESTROYED, LOST OR STOLEN TRUST CERTIFICATES.
If (a) any mutilated Trust Certificate shall be surrendered to the Certificate
Registrar, or if the Certificate Registrar shall receive evidence to its
satisfaction of the destruction, loss or theft of 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,
then in the absence of notice that such Trust Certificate shall have been
acquired by a bona fide purchaser, the Owner Trustee on behalf of the Trust
shall execute and 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 new Trust
Certificate of like class, 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 governmental charge that may be imposed in connection
therewith. Any duplicate Trust Certificate issued pursuant to this Section shall
constitute conclusive evidence of an ownership interest in the Trust, as if
originally issued, whether or not the lost, stolen or destroyed Trust
Certificate shall be found at any time.

          SECTION 3.6. PERSONS DEEMED CERTIFICATEHOLDERS. Every person by virtue
of becoming a Certificateholder or Owner in accordance with this Agreement shall
be deemed to be bound by the terms of this Agreement. Prior to due presentation
of a Trust Certificate for registration of transfer, the Owner Trustee or the
Certificate Registrar may treat the Person in whose name any Trust Certificate
shall be registered in the Certificate Register as the Owner of such Trust
Certificate for the purpose of receiving distributions pursuant to Section 5.2
and for all other purposes whatsoever, and neither the Owner Trustee nor the
Certificate Registrar shall be bound by any notice to the contrary.

          SECTION 3.7. ACCESS TO LIST OF CERTIFICATEHOLDERS' NAMES AND
ADDRESSES. The Owner Trustee shall furnish or cause to be furnished to the
Master Servicer, the Seller and the holder of the GP Interest, within ____ days
after receipt by the Owner Trustee of a request therefor from the Master
Servicer, the Seller or the holder of the GP Interest in writing, a list, in
such form as the Master Servicer, the Seller or the holder of the GP Interest
may reasonably require, of the names and addresses of the Certificateholders as
of the most recent Record Date. If three or more Holders of Trust Certificates
or one or more Holders of Trust Certificates evidencing not less than 25% of the
Certificate Balance apply in writing to the Owner Trustee, and such application
states that the applicants desire to communicate with other Certificateholders
with respect to their rights 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 either the Seller 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 OR AGENCY. The Owner Trustee shall
maintain in the Borough of Manhattan, The City of New York, an office or offices
or agency or agencies where Trust Certificates may be surrendered for
registration of transfer or exchange and where notices and demands to or upon
the Owner Trustee in respect of the Trust Certificates and the Basic Documents
may be served. The Owner Trustee initially designates _____________________ as
its principal corporate trust office for such purposes. The Owner Trustee shall
give prompt written notice to the Seller and to the Certificateholders of any
change in the location of the Certificate Register or any such office or agency.

          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. 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 the Owner
Trustee, and any co-paying agent chosen by the Owner Trustee, and acceptable to
the Master Servicer. The Paying Agent shall be permitted to resign upon 30 days'
written notice to the Owner Trustee and the Master Servicer. In the event that
the Owner Trustee shall no longer be the Paying Agent, the Owner Trustee shall
appoint a successor to act as Paying Agent (which shall be a bank or trust
company). The Owner Trustee shall cause such successor Paying Agent or any
additional Paying Agent appointed by the Owner Trustee to execute and deliver to
the Owner Trustee an instrument in which such successor Paying Agent or
additional Paying Agent shall agree with the Owner Trustee that as Paying Agent,
such successor Paying Agent or additional Paying Agent will hold all sums, if
any, held by it for payment to the Certificateholders in trust for the benefit
of the Certificateholders entitled thereto until such sums shall be paid to such
Certificateholders. The Paying Agent shall return all unclaimed funds to the
Owner Trustee and upon removal of a Paying Agent such Paying Agent shall also
return all funds in its possession to the Owner Trustee. The provisions of
Sections 7.1, 7.3, 7.4 and 8.1 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. RESERVED.

          SECTION 3.11. RESERVED.

          SECTION 3.12. DISPOSITION BY THE HOLDER OF THE GP INTEREST. On and
after the Closing Date, the holder of the GP Interest shall retain beneficial
and record ownership of Trust Certificates representing at least 1% of the
initial Certificate Balance. Any attempted transfer of any Trust Certificate
that would reduce such interest of the holder of the GP Interest below 1% of the
Certificate Balance shall be void. The Owner Trustee shall cause any Trust
Certificate issued to the holder of the GP Interest to contain a legend stating
"THIS CERTIFICATE IS NOT TRANSFERABLE".

          SECTION 3.13. RESERVED.

          SECTION 3.14. BOOK-ENTRY TRUST CERTIFICATES. The Trust Certificates,
upon original issuance, will be issued in the form of a typewritten Trust
Certificate or Trust Certificates representing Book-Entry Trust Certificates, to
be delivered to The Depository Trust Company, the initial Clearing Agency, by or
on behalf of the Trust; provided, however, that one Definitive Certificate (as
defined below) may be issued to GP Holder, Inc., as holder of the GP Interest
pursuant to Section 2.7. Such Book-Entry Trust Certificate or Trust Certificates
shall initially be registered on the Certificate Register in the name of Cede &
Co., the nominee of the initial Clearing Agency, and no beneficial owner (other
than the Seller and the holder of the GP Interest) will receive a definitive
Trust Certificate representing such beneficial owner's interest in such Trust
Certificate, except as provided in Section 3.16. Unless and until Definitive
Trust Certificates have been issued to beneficial owners pursuant to Section
3.16:

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

               (ii) the Certificate Registrar and the Owner Trustee shall be
          entitled to deal with the Clearing Agency for all purposes of this
          Agreement relating to the Book-Entry Trust Certificates (including the
          payment of principal of and interest on the Book-Entry Trust
          Certificates and the giving of instructions or directions to Owners of
          Book-Entry Trust Certificates) as the sole Holder of Book-Entry Trust
          Certificates and shall have no obligations to the Owners thereof;

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

               (iv) the rights of the Owners of the Book-Entry Trust
          Certificates shall be exercised only through the Clearing Agency and
          shall be limited to those established by law and agreements between
          such Owners and the Clearing Agency and/or the Clearing Agency
          Participants. Pursuant to the Certificate Depository Agreement, unless
          and until Definitive Trust Certificates are issued pursuant to Section
          3.16, the initial Clearing Agency will make book-entry transfers among
          the Clearing Agency Participants and receive and transmit payments of
          principal of and interest on the Book-Entry Trust Certificates to such
          Clearing Agency Participants; and

               (v) whenever this Agreement requires or permits actions to be
          taken based 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 Owners and/or Clearing Agency Participants owning or
          representing, respectively, such required percentage of the beneficial
          interest in the Book-Entry Trust Certificates and has delivered such
          instructions to the Owner Trustee.

          SECTION 3.15. NOTICES TO CLEARING AGENCY. Whenever a notice or other
communication to the Owners is required under this Agreement, unless and until
Definitive Trust Certificates shall have been issued to Owners pursuant to
Section 3.16, the Owner Trustee shall give all such notices and communications
specified herein to be given to Owners to the Clearing Agency, and shall have no
obligations to the Owners, except to the holder of the GP Interest.

          SECTION 3.16. DEFINITIVE TRUST CERTIFICATES. If (i) the Master
Servicer advises the Owner Trustee in writing that the Clearing Agency is no
longer willing or able to properly discharge its responsibilities with respect
to the Trust Certificates, and the Master Servicer is unable to locate a
qualified successor, (ii) the Master Servicer at its option advises the Owner
Trustee in writing that it elects to terminate the book-entry system through the
Clearing Agency or (iii) after the occurrence of an Event of Default, Owners of
Certificates representing beneficial interests aggregating at least a majority
of the Certificate Balance advise the Clearing Agency in writing that the
continuation of a book-entry system through the Clearing Agency is no longer in
the best interest of the Owners of Trust Certificates, then the Clearing Agency
shall notify all Owners and the Owner Trustee of the occurrence of any such
event and of the availability of the Definitive Trust Certificates to 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 Certificateholders. The Definitive Trust
Certificates shall be printed, lithographed or engraved or may be produced in
any other manner as is reasonably acceptable to the Owner Trustee, as evidenced
by its execution thereof.

          five Business Days thereof.

          SECTION 4.4. RESTRICTIONS ON CERTIFICATEHOLDERS' POWER. The
Certificateholders shall not direct the Owner Trustee to take or refrain from
taking any action if such action or inaction would be contrary to any obligation
of the Trust or the Owner Trustee under this Agreement or any of the Basic
Documents or would be contrary to Section 2.3 nor shall the Owner Trustee be
obligated to follow any such direction, if given.

          SECTION 4.5. MAJORITY CONTROL. Except as expressly provided herein,
any action that may be taken by the Certificateholders under this Agreement may
be taken by the Holders of Trust Certificates evidencing not less than a

shall be effective if signed by Holders of Certificates evidencing not less than
a majority of the Certificate Balance at the time of the delivery of such
notice.

                                    ARTICLE V

                   Application of Trust Funds: Certain Duties

          SECTION 5.1. ESTABLISHMENT OF CERTIFICATE DISTRIBUTION 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. Except as
otherwise provided herein, the Certificate Distribution Account shall be under
the sole dominion and control of the Owner Trustee for the benefit of the
Certificateholders.

          SECTION 5.2. APPLICATION OF FUNDS IN CERTIFICATE DISTRIBUTION ACCOUNT.

               (a) On each Distribution Date, the Owner Trustee will, based on
          the information contained in the Master Servicer's Certificate
          delivered on the related Determination Date pursuant to Section ____
          of the Master Servicing Agreement, distribute to Certificateholders,
          to the extent of the funds available, amounts deposited in the
          Certificate Distribution Account pursuant to Section ____ of the
          Master Servicing Agreement on such Distribution Date in the following
          order of priority:

                    (i) first, to the Certificateholders, on a pro rata basis,
               an amount equal to the Certificateholders' Interest Distributable
               Amount; and

                    (ii) second, to the Certificateholders, on a pro rata basis,
               an amount equal to the Certificateholders' Principal
               Distributable Amount.

               (b) On each Distribution Date, the Owner Trustee shall send to
          each Certificateholder the statement provided to the Owner Trustee by
          the Master Servicer pursuant to Section ____ of the Master Servicing
          Agreement on such Distribution Date.

               (c) In the event that any withholding tax is imposed on the
          Trust's payment (or allocations of income) to a Certificateholder,
          such tax shall reduce the amount otherwise distributable to the
          Certificateholder in accordance with this Section. The Owner Trustee
          is hereby authorized and directed to retain from amounts otherwise
          distributable to the Certificateholders sufficient funds for the
          payment of any tax that is legally owed by the Trust (but such
          authorization shall not prevent the Owner Trustee from contesting any
          such tax in appropriate proceedings, and withholding payment of such
          tax, if permitted by law, pending the outcome of such proceedings).
          The amount of any withholding tax imposed with respect to a
          Certificateholder shall be treated as cash distributed to such
          Certificateholder 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-US Certificateholder), the Owner Trustee may in
          it sole discretion withhold such amounts in accordance with this
          clause (c). In the event that an Owner wishes to apply for a refund of
          any such withholding tax, the Owner Trustee shall reasonably cooperate
          with such Certificateholder in making such claim so long as such
          Certificateholder agrees to reimburse the Owner Trustee for any
          out-of-pocket expenses incurred.

          SECTION 5.3. RESERVED.

          SECTION 5.4. METHOD OF PAYMENT. Subject to Section 9.1(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 (i)
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 (ii) such Certificateholder is
the holder of the GP Interest, or an Affiliate thereof, or, if not, by check
mailed to such Certificateholder at the address of such holder appearing in the
Certificate Register; provided, however, that, unless Definitive Certificates
have been issued pursuant to Section 3.16, 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.), distributions will be made by wire
transfer in immediately available funds to the account designated by such
nominee. Notwithstanding the foregoing, the final distribution in respect of any
Trust Certificate (whether on the Final Scheduled Distribution Date or
otherwise) will be payable only upon presentation and surrender of such Trust
Certificate at the office or agency maintained for that purpose by the Owner
Trustee pursuant to Section 3.8.

          SECTION 5.5. NO SEGREGATION OF MONIES; NO INTEREST. Subject to
Sections 5.1 and 5.2, monies received by the Owner Trustee hereunder need not be
segregated in any manner except to the extent required by law 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 5.6. ACCOUNTING AND REPORTS TO THE NOTEHOLDERS,
CERTIFICATEHOLDERS, THE INTERNAL REVENUE SERVICE AND OTHERS. Subject to Sections
____ and ____ of the Master Servicing Agreement, the holder of the GP Interest
shall (a) maintain (or cause to be maintained) the books of the Trust on a
calendar year basis on the accrual method of accounting, (b) deliver (or cause
to be delivered) to each Certificateholder, as may be required by the Code and
applicable Treasury Regulations, such information as may be required (including
Schedule K-1) to enable each Certificateholder to prepare its Federal and state
income tax returns, (c) file or cause to be filed such tax returns relating to
the Trust (including a partnership information return, Form 1065), and direct
the Owner Trustee to make such elections as may from time to time be required or
appropriate under any applicable state or Federal statute or rule or regulation
thereunder so as to maintain the Trust's characterization as a partnership for
Federal income tax purposes and (d) collect or cause to be collected any
withholding tax as described in and in accordance with Section 5.2(c) with
respect to income or distributions to Certificateholders. The Owner Trustee
shall make all elections pursuant to this Section as directed by the holder of
the GP Interest. The Owner Trustee shall sign all tax information returns filed
pursuant to this Section 5.6 and any other returns as may be required by law,
and in doing so shall rely entirely upon, and shall have no liability for
information provided by, or calculations provided by, the holder of the GP
Interest. 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 5.7. SIGNATURE ON RETURNS; TAX MATTERS PARTNER. (a)
Notwithstanding the provisions of Section 5.6, the Owner Trustee shall sign on
behalf of the Trust the tax returns of the Trust, unless applicable law requires
a Certificateholder or an Owner to sign such documents, in which case such
documents shall be signed by the holder of the GP Interest.

               (b) The holder of the GP Interest shall be the "tax matters
          partner" of the Trust pursuant to the Code.

                                   ARTICLE VI

                      Authority and Duties of Owner Trustee

          SECTION 6.1. GENERAL AUTHORITY. The Owner Trustee is authorized and
directed to execute and deliver the Basic Documents to which the Trust is named
as a party and each certificate or other document attached as an exhibit to or
contemplated by the Basic Documents to which the Trust is named as a party and
any amendment thereto, in each case, in such form as the Seller shall approve as
evidenced conclusively by the Owner Trustee's execution thereof, and on behalf
of the Trust, to direct the Trustee to authenticate and deliver [LIST THE
CLASSES OF NOTES AND AGGREGATE CURRENT PRINCIPAL AMOUNT(S)]. 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
Master Servicer recommends with respect to the Basic Documents.

          SECTION 6.2. GENERAL DUTIES. It shall be the duty of the Owner Trustee
to discharge (or cause to be discharged) all of its responsibilities pursuant to
the terms of this Agreement and the Master Servicing Agreement 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
Master Servicer has agreed in the Master Servicing 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 Master Servicer to carry out its obligations under the Master Servicing
Agreement.

          SECTION 6.3. ACTION UPON INSTRUCTION.

               (a) Subject to Article IV, 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 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 any Basic Document, the Owner Trustee shall promptly
          give notice (in such form as shall be appropriate under the
          circumstances) to 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 written instruction
          of the Certificateholders 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 inconsistent with this Agreement or the Basic
          Documents, as it shall deem to be in the best interests of the
          Certificateholders, 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 Certificateholders
          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
          Certificateholders, and shall have no liability to any Person for such
          action or inaction.

          SECTION 6.4. NO DUTIES EXCEPT AS SPECIFIED IN THIS AGREEMENT OR IN
INSTRUCTIONS. The Owner Trustee shall not have any duty or obligation to manage,
make any payment with respect to, register, record, sell, dispose of, or
otherwise deal with the Owner Trust Estate, or to otherwise take or refrain from
taking any action under, or in connection with, any document contemplated hereby
to which the Owner Trustee is a party, except as expressly provided by the terms
of this Agreement or in any document or written instruction received by the
Owner Trustee pursuant to Section 6.3; and no implied duties or obligations
shall be read into this Agreement or any Basic Document against the Owner
Trustee. The Owner Trustee shall have no responsibility for filing any financing
or continuation statement in any public office at any time or to otherwise
perfect or maintain the perfection of any security interest or lien granted to
it hereunder or to prepare or file any 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 6.5. NO ACTION EXCEPT UNDER SPECIFIED DOCUMENTS OR
INSTRUCTIONS. The Owner Trustee shall not manage, control, use, sell, dispose of
or otherwise deal with any part of the Owner Trust Estate except (i) in
accordance with the powers granted to and the authority conferred upon the Owner
Trustee pursuant to this Agreement, (ii) in accordance with the Basic Documents
and (iii) in accordance with any document or instruction delivered to the Owner
Trustee pursuant to Section 6.3.

          SECTION 6.6. RESTRICTIONS. The Owner Trustee shall not take any action
(a) that is inconsistent with the purposes of the Trust set forth in Section 2.3
or (b) that, to the actual knowledge of the Owner Trustee, would result in the
Trust's becoming taxable as a corporation for Federal income tax purposes. The
Certificateholders shall not direct the Owner Trustee to take action that would
violate the provisions of this Section.

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

               (d) under no circumstances shall the Owner Trustee be liable for
          indebtedness evidenced by or arising under any of the Basic Documents,

          Estate or for or in respect of the validity or sufficiency of the
          Basic Documents, other than the certificate of authentication on the

          performed by the Trustee under the Indenture or the Master Servicer
          under the Master Servicing Agreement; and

               (g) the Owner Trustee shall be under no obligation to exercise
          any of the rights or powers vested in it by this Agreement, or to
          institute, conduct or defend any litigation under this Agreement or
          otherwise or in relation to this Agreement or any Basic Document, at
          the request, order or direction of any of the Certificateholders,
          unless 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, bad faith or willful misconduct in the
          performance of any such act.

          Agreement, nor the consummation by it of the transactions contemplated
          hereby nor compliance by it with any of the terms or provisions hereof

          law, governmental rule or regulation governing the banking or trust
          powers of the Owner Trustee or any judgment or order binding on it, or
          constitute any default under its charter documents or by-laws or any
          indenture, mortgage, contract, agreement or instrument to which it is
          a party or by which any of its properties may be bound.

          SECTION 7.4. RELIANCE; ADVICE OF COUNSEL.

               (a) The Owner Trustee shall incur no liability to anyone in
          acting upon any signature, instrument, notice, resolution, request,

          by the proper party or parties. The Owner Trustee may accept a
          certified copy of a resolution of the board of directors or other
          governing body of any corporate party as conclusive evidence that such
          resolution has been duly adopted by such body and that the same is in
          full force and effect. As to any fact or matter the method of the
          determination of which is not specifically prescribed herein, the
          Owner Trustee may for all purposes hereof rely on a certificate,
          signed by the president or any vice president or by the treasurer,
          secretary or other authorized officers of the relevant party, as to
          such fact or matter, and such certificate shall constitute full

          or the Basic Documents, the Owner Trustee (i) may act directly or
          through its agents or attorneys pursuant to agreements entered into
          with any of them, and the Owner Trustee shall not be liable for the
          conduct or misconduct of such agents or attorneys if such agents or
          attorneys shall have been selected by the Owner Trustee with
          reasonable care, and (ii) may consult with counsel, accountants and
          other skilled persons to be selected with reasonable care and employed
          by it. The Owner Trustee shall not be liable for anything done,
          suffered or omitted in good faith by it in accordance with the written
          opinion or advice of any such counsel, accountants or other such
          persons and not contrary to this Agreement or any Basic Document.

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

          SECTION 7.6. OWNER TRUSTEE NOT LIABLE FOR TRUST CERTIFICATES OR
MORTGAGE LOANS. The recitals contained herein and in the Trust Certificates
(other than the signature and countersignature of the Owner Trustee on the Trust
Certificates) shall be taken as the statements of the Seller and the Owner
Trustee assumes no responsibility for the correctness thereof. The Owner Trustee
makes no representations as to the validity or sufficiency of this Agreement, of
any Basic Document or of the Trust Certificates (other than the signature and
countersignature of the Owner Trustee on the Trust Certificates) or the Notes,
or of any Mortgage Loan or related documents. The Owner Trustee shall at no time
have any responsibility or liability for or with respect to the legality,
validity and enforceability of any Mortgage Loan, or the perfection and priority
of any security interest created by any Mortgage Loan in any Mortgaged Property
or the maintenance of any such perfection and priority, or for or with respect
to the sufficiency of the Owner Trust Estate or its ability to generate the
payments to be distributed to Certificateholders under this Agreement or the
Noteholders under the Indenture, including, without limitation: the existence,
condition and ownership of any Mortgaged Property; the existence and
enforceability of any insurance thereon; the existence and contents of any
Mortgage Loan on any computer or other record thereof; the validity of the
assignment of any Mortgage Loan to the Trust or of any intervening assignment;
the completeness of any Mortgage Loan; the performance or enforcement of any
Mortgage Loan; the compliance by the Seller or the Master Servicer with any
warranty or representation made under any Basic Document or in any related
document or the accuracy of any such warranty or representation or any action of
the Trustee or the Master Servicer or any subservicer taken in the name of the
Owner Trustee.

          SECTION 7.7. OWNER TRUSTEE MAY OWN TRUST CERTIFICATES AND NOTES. The
Owner Trustee in its individual or any other capacity may become the owner or
pledgee of Trust Certificates or Notes and may deal with the Seller, the Trustee
and the Master Servicer in banking transactions with the same rights as it would
have if it were not Owner Trustee.

                                  ARTICLE VIII

separately agreed upon before the date hereof between the Seller and the Owner
Trustee, and the Owner Trustee shall be entitled to be reimbursed by the holder
of the GP Interest for its other reasonable expenses hereunder, including the
reasonable compensation, expenses and disbursements of such agents,
representatives, experts and counsel as the Owner Trustee may employ in
connection with the exercise and performance of its rights and its duties
hereunder.

          SECTION 8.2. INDEMNIFICATION. The holder of the GP Interest 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
Basic Documents, the Owner Trust Estate, the administration of the Owner Trust
Estate or the action or inaction of the Owner Trustee hereunder, except only
that the holder of the GP Interest shall not be liable for or required to
indemnify the Owner Trustee from and against Expenses arising or resulting from
any of the matters described in the third sentence of Section 7.1. The
indemnities contained in this Section shall survive the resignation or
termination of the Owner Trustee or the termination of this Agreement. In any
event of any claim, action or proceeding for which indemnity will be sought
pursuant to this Section, the Owner Trustee's choice of legal counsel shall be
subject to the approval of the holder of the GP Interest, which approval shall
not be unreasonably withheld.

          SECTION 8.3. PAYMENTS TO THE OWNER TRUSTEE. Any amounts paid to the
Owner Trustee pursuant to this Article VIII shall be deemed not to be a part of
the Owner Trust Estate immediately after such payment.

                                   ARTICLE IX

                         Termination of Trust Agreement

          SECTION 9.1. TERMINATION OF TRUST AGREEMENT.

               (a) This Agreement (other than Article VIII) and the Trust shall
          terminate and be of no further force or effect, (i) upon the final
          distribution by the Owner Trustee of all moneys or other property or
          proceeds of the Owner Trust Estate in accordance with the terms of the
          Indenture, the Master Servicing Agreement and Article V or (ii) at the
          time provided in Section 9.2. The bankruptcy, liquidation,
          dissolution, death or incapacity of any Certificateholder or Owner,
          other than the holder of the GP Interest as described in Section 9.2,
          shall not (x) operate to terminate this Agreement or the Trust, or (y)
          entitle such Certificateholder's or Owner's legal representatives or
          heirs to claim an accounting or to take any action or proceeding in
          any court for a partition or winding up of all or any part of the
          Trust or Owner Trust Estate or (z) otherwise affect the rights,
          obligations and liabilities of the parties hereto.

               (b) Except as provided in clause (a), neither the Seller nor the
          holder of the GP Interest nor any Certificateholder shall be entitled
          to revoke or terminate the Trust.

               (c) Notice of any termination of the Trust, specifying the
          Distribution Date upon which the Certificateholders shall surrender
          their Trust Certificates to the Paying Agent for payment of the final
          distribution and cancellation, shall be given by the Owner Trustee by
          letter to Certificateholders mailed within five Business Days of
          receipt of notice of such termination from the Master Servicer given
          pursuant to Section ____ of the Master Servicing Agreement, stating
          (i) the Distribution Date upon or with respect to which final payment
          of the Trust Certificates shall be made upon presentation and
          surrender of the Trust 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 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 5.2.

               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, subject to
          applicable escheat laws, by the Owner Trustee to the holder of the GP
          Interest.

               (d) Any funds remaining in the Trust after funds for final
          distribution have been distributed or set aside for distribution shall
          be distributed by the Owner Trustee to the holder of the GP Interest
          (other than any amounts remaining in the Reserve Account which shall
          be distributed to the Seller).

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

          SECTION 9.2. DISSOLUTION UPON BANKRUPTCY OF THE HOLDER OF THE GP
INTEREST. In the event that an Insolvency Event shall occur with respect to the
holder of the GP Interest, this Agreement shall be terminated in accordance with
Section 9.1 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 Certificateholders holding a majority of the Certificate
Balance (other than the holder of the GP Interest) 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
the holder of the GP Interest, (i) the holder of the GP Interest shall give the
Trustee and the Owner Trustee written notice of such Insolvency Event, (ii) the
Owner Trustee shall, upon the receipt of such written notice from the holder of
the GP Interest, give prompt written notice to the Certificateholders and the
Trustee of the occurrence of such event and (iii) the Trustee shall, upon
receipt of written notice of such Insolvency Event from the Owner Trustee or the
holder of the GP Interest, 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 9.2.
Upon a termination pursuant to this Section, the Owner Trustee shall direct the
Trustee promptly to sell the assets of the Owner Trust Estate in a commercially
reasonable manner and on commercially reasonable terms. The proceeds of such a
sale of the assets of the Trust shall be treated as collections under the Master
Servicing Agreement and shall be distributed in accordance with Section 9.1(b)
thereof.

                                    ARTICLE X

             Successor Owner Trustees and Additional Owner Trustees

          SECTION 10.1. ELIGIBILITY REQUIREMENTS FOR OWNER TRUSTEE. The Owner
Trustee shall at all times be a corporation authorized to exercise corporate
trust powers; and having a combined capital and surplus of at least
$______________ and subject to supervision or examination by Federal or state
authorities. 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 10.2. In addition, at all
times the Owner Trustee or a co-trustee shall be a person that satisfies the
requirements of Section 3807(a) of the Business Trust Statute (the "Delaware
Trustee").

          SECTION 10.2. RESIGNATION OR REMOVAL OF OWNER TRUSTEE. The Owner
Trustee may at any time resign and be discharged from the trusts hereby created
by giving written notice thereof to the Master Servicer. Upon receiving such
notice of resignation, the Master Servicer 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 10.1 and shall fail to resign after
written request therefor by the Master Servicer, or if at any time the Owner
Trustee shall be legally unable to act, or shall be adjudged bankrupt or
insolvent, or a receiver of the Owner Trustee or of its property shall be
appointed, or any public officer shall take charge or control of the Owner
Trustee or of its property or affairs for the purpose of rehabilitation,
conservation or liquidation, then the Master Servicer may remove the Owner
Trustee. If the Master Servicer shall remove the Owner Trustee under the
authority of the immediately preceding sentence, the Master Servicer 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 payment of all fees owed
to the outgoing Owner Trustee.

          Any resignation or removal of the Owner Trustee and appointment of a
successor Owner Trustee pursuant to any of the provisions of this Section shall
not become effective until acceptance of appointment by the successor Owner
Trustee pursuant to Section 10.3 and payment of all fees and expenses owed to
the outgoing Owner Trustee. The Master Servicer shall provide notice of such
resignation or removal of the Owner Trustee to each of the Rating Agencies.

          SECTION 10.3. SUCCESSOR OWNER TRUSTEE. Any successor Owner Trustee
appointed pursuant to Section 10.2 shall execute, acknowledge and deliver to the
Master Servicer 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 Master Servicer and the predecessor Owner Trustee
shall execute and deliver such instruments and do such other things as may
reasonably be required for fully and certainly vesting and confirming in the
successor Owner Trustee all such rights, powers, duties and obligations.

          No successor Owner Trustee shall accept appointment as provided in
this Section unless at the time of such acceptance such successor Owner Trustee
shall be eligible pursuant to Section 10.1.

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

          SECTION 10.4. MERGER OR CONSOLIDATION OF OWNER TRUSTEE. Any
corporation into which the Owner Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Owner Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Owner Trustee, shall be the successor of the Owner Trustee
hereunder, provided such corporation shall be eligible pursuant to Section 10.1,
without the execution or filing of any instrument or any further act on the part
of any of the parties hereto, anything herein to the contrary notwithstanding;
provided further that the Owner Trustee shall mail notice of such merger or
consolidation to the Rating Agencies.

          SECTION 10.5. APPOINTMENT OF CO-TRUSTEE OR SEPARATE TRUSTEE.
Notwithstanding any other provisions of this Agreement, at any time, for the
purpose of meeting any legal requirements of any jurisdiction in which any part
of the Owner Trust Estate or any Mortgaged Property may at the time be located,
the Master Servicer and the Owner Trustee acting jointly shall have the power
and shall execute and deliver all instruments to appoint one or more Persons
approved by the Owner Trustee to act as co-trustee, jointly with the Owner
Trustee, or separate trustee or separate trustees, of all or any part of the
Owner Trust Estate, and to vest in such Person, in such capacity, such title to
the Trust, or any part thereof, and, subject to the other provisions of this
Section, such powers, duties, obligations, rights and trusts as the Master
Servicer and the Owner Trustee may consider necessary or desirable. If the
Master Servicer shall not have joined in such appointment within 15 days after
the receipt by it of a request so to do, the Owner Trustee alone shall have the
power to make such appointment. Pursuant to the Co-Trustee Agreement, dated as
of ______________, 200_, between and , the Owner Trustee shall appoint as a
co-trustee hereunder for the purpose of his acting as Delaware Trustee and such
agreement is hereby incorporated herein by reference. If the Delaware Trustee
shall die, become incapable of acting, resign or be removed, unless the Owner
Trustee is qualified to act as Delaware Trustee, a successor co-trustee shall
promptly be appointed in the manner specified in this Section 10.5 to act as
Delaware Trustee. No co-trustee or separate trustee under this Agreement shall
be required to meet the terms of eligibility as a successor trustee pursuant to
Section 10.1 and no notice of the appointment of any co-trustee or separate
trustee shall be required pursuant to Section 10.3.

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

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

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

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

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

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

                                   ARTICLE XI

                                  Miscellaneous

          SECTION 11.1. SUPPLEMENTS AND AMENDMENTS. This Agreement may be
amended by the Seller and the Owner Trustee, with prior written notice to the
Rating Agencies, without the consent of any of the Noteholders or the
Certificateholders, to cure any ambiguity or defect, to correct or supplement
any provisions in this Agreement or for the purpose of adding any provisions to
or changing in any manner or eliminating any of the provisions in this Agreement
or of modifying in any manner the rights of the Noteholders or the
Certificateholders; provided, however, that such action shall not, as evidenced
by an Opinion of Counsel, adversely affect in any material respect the interests
of any Noteholder or Certificateholder.

          This Agreement may also be amended from time to time by the Seller and
the Owner Trustee, with prior written notice to the Rating Agencies, with the
consent of the Holders of Notes evidencing not less than a majority of the
Outstanding Amount of the Notes and, to the extent affected thereby, the consent
of the Holders of Certificates evidencing not less than a majority of the
Certificate Balance for the purpose of adding any provisions to or changing in
any manner or eliminating any of the provisions of this Agreement or of
modifying in any manner the rights of the Noteholders or the Certificateholders;
provided, however, that no such amendment shall (a) increase or reduce in any
manner the amount of, or accelerate or delay the timing of, collections of
payments on Mortgage Loans or distributions that shall be required to be made
for the benefit of the Noteholders or the Certificateholders or (b) reduce the
aforesaid percentage of the Outstanding Amount of the Notes and the [Current
Principal Amount] required to consent to any such amendment, without the consent
of the Holders of all the outstanding Notes and Holders of all outstanding
Certificates.

          Promptly after the execution of any such amendment or consent, the
Owner Trustee shall furnish written notification of the substance of such
amendment or consent to each Certificateholder, the Trustee and each of the
Rating Agencies.

          It shall not be necessary for the consent of Certificateholders, the
Noteholders or the Trustee pursuant to this Section to approve the particular
form of any proposed amendment or consent, but it shall be sufficient if such
consent shall approve the substance thereof. The manner of obtaining such
consents (and any other consents of Certificateholders provided for in this
Agreement or in any other Basic Document) and of evidencing the authorization of
the execution thereof by Certificateholders shall be subject to such reasonable
requirements as the Owner Trustee may prescribe.

          Promptly after the execution of any amendment to the Certificate of
Trust, the Owner Trustee shall cause the filing of such amendment with the
Secretary of State.

          Prior to the execution of any amendment to this Agreement or the
Certificate of Trust, the Owner Trustee shall be entitled to receive and rely
upon an Opinion of Counsel stating that the execution of such amendment is
authorized or permitted by this Agreement and that all conditions precedent to
the execution and delivery of such amendment have been satisfied. The Owner
Trustee may, but shall not be obligated to, enter into any such amendment which
affects the Owner Trustee's own rights, duties or immunities under this
Agreement or otherwise.

          SECTION 11.2. NO LEGAL TITLE TO OWNER TRUST ESTATE IN
CERTIFICATEHOLDERS. The Certificateholders shall not have legal title to any
part of the Owner Trust Estate. The Certificateholders shall be entitled to
receive distributions with respect to their undivided ownership interest therein
only in accordance with Articles V and IX. No transfer, by operation of law or
otherwise, of any right, title or interest of the Certificateholders to and in
their ownership interest in the Owner Trust Estate shall operate to terminate
this Agreement or the trusts hereunder or entitle any transferee to an
accounting or to the transfer to it of legal title to any part of the Owner
Trust Estate.

          SECTION 11.3. LIMITATIONS ON RIGHTS OF OTHERS. Except for Section 2.7,
the provisions of this Agreement are solely for the benefit of the Owner
Trustee, the Seller, the Certificateholders, the Master Servicer and, to the
extent expressly provided herein, the Trustee and the Noteholders, and nothing
in this Agreement, whether express or implied, shall be construed to give to any
other Person any legal or equitable right, remedy or claim in the Owner Trust
Estate or under or in respect of this Agreement or any covenants, conditions or
provisions contained herein.

          SECTION 11.4. NOTICES.

               (a) Unless otherwise expressly specified or permitted by the
          terms hereof, all notices shall be in writing and shall be deemed
          given upon receipt personally delivered, delivered by overnight

          Certificateholder shall be given by first-class mail, postage prepaid,
          at the address of such Holder as shown in the Certificate Register.
          Any notice so mailed within the time prescribed in this Agreement
          shall be conclusively presumed to have been duly given, whether or not
          the Certificateholder receives such notice.

          SECTION 11.5. SEVERABILITY. Any provision of this Agreement that is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or

unenforceable such provision in any other jurisdiction.

          SECTION 11.6. SEPARATE COUNTERPARTS. This Agreement may be executed by
the parties hereto in separate counterparts, each of which when so executed and
delivered shall be an original, but all such counterparts shall together
constitute but one and the same instrument.

contained herein shall be binding upon, and inure to the benefit of, the Seller,
the holder of the GP Interest, the Owner Trustee and its successors and each
Certificateholder and its successors and permitted assigns, all as herein
provided. Any request, notice, direction, consent, waiver or other instrument or
action by a Certificateholder shall bind the successors and assigns of such
Certificateholder.

          SECTION 11.8. RESERVED.

          SECTION 11.9. NO PETITION. The Owner Trustee (not in its individual
capacity but solely as Owner Trustee), by entering into this Agreement, each
Certificateholder, by accepting a Trust Certificate, and the Trustee and each
Noteholder by accepting the benefits of this Agreement, hereby covenants and
agrees that they will not at any time institute against the holder of the GP
Interest, or join in any institution against the holder of the GP Interest of,
any bankruptcy, reorganization, arrangement, insolvency or liquidation

bankruptcy or similar law in connection with any obligations relating to the
Trust Certificates, the Notes, this Agreement or any of the Basic Documents.

          SECTION 11.10. NO RECOURSE. Each Certificateholder by accepting a
Trust Certificate acknowledges that such Certificateholder's Trust Certificates
represent beneficial interests in the Trust only and do not represent interests
in or obligations of the Seller, the Master Servicer, the holder of the GP
Interest, the Owner Trustee, the Trustee or any Affiliate thereof and no
recourse may be had against such parties or their assets, except as may be
expressly set forth or contemplated in this Agreement, the Trust Certificates or
the Basic Documents.

execute on behalf of the Trust all such documents, reports, filings,
instruments, certificates and opinions as it shall be the duty of the Trust to

The Trust was created pursuant to a Trust Agreement dated as of ____________,
200_ (the "Trust Agreement"), between the Seller 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 Trust Certificates designated as
Mortgage-Backed Certificates (herein called the "Trust Certificates"). Also
issued under the Indenture dated as of ____________, 200_, between the Trust and
____________, as trustee, are classes of Notes designated as [LIST THE CLASSES

by which such holder is bound. The property of the Trust includes (i) mortgage
loans or participations therein secured by one- to four-family residential

Notes have been paid in full. 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 Master Servicing Agreement, the Indenture and the Trust Agreement, as
applicable.

It is the intent of the Seller, Master Servicer, holder of the GP Interest and
Certificateholders that, for purposes of Federal income taxes, the Trust will be
treated as a partnership and the Certificateholders (including the holder of the
GP Interest) will be treated as partners in that partnership. The holder of the
GP Interest and the other Certificateholders by acceptance of a Trust
Certificate, agree to treat, and to take no action inconsistent with the
treatment of, the Trust Certificates for such tax purposes as partnership
interests in the Trust.

Each Certificateholder, by its acceptance of a Trust Certificate, covenants and
agrees that such Certificateholder will not at any time institute against the
holder of the GP Interest, or join in any institution against the holder of the
GP Interest 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 Trust 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 the 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.

Unless the certificate of authentication hereon shall have been executed by an
authorized officer of the Owner Trustee, by manual signature, this Trust
Certificate shall not entitle the holder hereof to any benefit under the Trust
Agreement or the Master Servicing Agreement or be valid for any purpose.

THIS TRUST CERTIFICATE SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE
STATE OF DELAWARE, WITHOUT REFERENCE TO ITS CONFLICT OF LAW PROVISIONS, AND THE
OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN
ACCORDANCE WITH SUCH LAWS.

                         (Reverse of Trust Certificate)

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

The Trust Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Seller and the rights of the Certificateholders under the Trust Agreement at any
time by the Seller and the Owner Trustee with the consent of the holders of the
Notes and the Trust Certificates evidencing not less than a majority of the
outstanding Notes and the [Certificate Balance]. 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 hereof 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 in 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
____________, ____________, ____________.

Except for Trust Certificates issued to the Seller and transferred to the holder
of the GP Interest, the Trust Certificates are issuable only as registered Trust
Certificates without coupons in denominations of $1,000 or integral multiples
thereof; except as otherwise provided in the Trust Agreement. As provided in the
Trust Agreement and subject to certain limitations therein set forth, Trust
Certificates are exchangeable for new Trust Certificates in 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 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 Trust
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
Master Servicing Agreement and the disposition of all property held as part of
the Trust. The Seller of the Mortgage Loans may at its option purchase the
corpus of the Trust at a price specified in the Master 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, subject to certain restrictions, only as of the last day of any
Collection Period as of which the Pool Balance is ___% or less 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 1
of ERISA, (b) a plan described in Section 4975(e) (l) 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.

to be recorded, but shall not be required to determine whether any Person
executing any document is authorized to do so or whether any signature thereon
is genuine.

subject to the review and period for delivery provided for in Section 2.1, its

assignment, in each case without recourse, as shall be necessary to vest in the
Seller or its designee any Mortgage Loan released pursuant hereto. It is

equivalent to those required for approval by Fannie Mae or Freddie Mac. The
Master Servicer may perform its responsibilities relating to servicing through
other agents or independent contractors, but shall not thereby be released from
any of its responsibilities as hereinafter set forth. The authority of the
Master Servicer, in its capacity as Master Servicer, shall include the power to
(i) supervise the filing and collection of insurance claims and take or cause to
be taken such actions on behalf of the insured person thereunder as shall be
reasonably necessary to prevent the denial of coverage thereunder, and (ii)
effectuate foreclosure or other conversion of the ownership of the Mortgaged
Property securing a related Mortgage Loan, including the employment of
attorneys, the institution of legal proceedings, the collection of deficiency
judgments, the acceptance of compromise proposals, the filing of claims under
any Primary Insurance Policy and any other matter pertaining to a delinquent
Mortgage Loan. The authority of the Master Servicer shall include, in addition,
the power to (i) execute and deliver customary consents or waivers and other
instruments and documents, (ii) consent to transfers of any related Mortgaged
Property and assumptions of the related Mortgage Notes and Security Instruments
(but only in the manner provided in this Agreement) and (iii) collect any
Insurance Proceeds and Liquidation Proceeds. Without limiting the generality of
the foregoing, the Master Servicer is authorized and empowered to execute and
deliver, on behalf of itself, the Issuer, the Owner Trustee, the Trustee, the
Certificateholders and the Noteholders or any of them, any and all instruments
of satisfaction or cancellation, or partial or full release or discharge, and
all other comparable instruments, with respect to such Mortgage Loans or to the
Mortgaged Properties securing such Mortgage Loans.

               (b) Notwithstanding the provisions of Subsection 3.1(a), the
Master Servicer shall not take any action inconsistent with the interest of the
Noteholders or the Certificateholders in the Mortgage Loans or with the rights
and interests of the Owner Trustee, the Trustee, the Noteholders or the
Certificateholders under this Agreement.

               (c) The Owner Trustee shall furnish the Master Servicer with any
powers of attorney and other documents in form as provided to it necessary or
appropriate (as certified to the Owner Trustee by the Master Servicer) to enable
the Master Servicer to service and administer the related Mortgage Loans and REO
Property.

          SECTION 3.2. COLLECTION AND ALLOCATION OF MORTGAGE LOAN PAYMENTS. (a)
The Master Servicer shall make reasonable efforts to collect all payments called
for under the terms and provisions of the Mortgage Loans as and when the same
shall become due and shall follow such collection procedures as it follows with
respect to all mortgage loans in its servicing portfolio comparable to the
Mortgage Loans that it services for itself or others.

               (b) Consistent with the terms of this Agreement, the Master
Servicer may waive, modify or vary any term of any Mortgage Loan or consent to
the postponement of strict compliance with any such term or in any manner grant
indulgence to any Mortgagor if in the Master Servicer's determination such
waiver, modification, postponement or indulgence is not materially adverse to
the interests of the Noteholders and the Certificateholders; provided, however,
that the Master Servicer may not permit any modification with respect to any
Mortgage Loan that would change the Mortgage Rate, defer or forgive the payment
of any principal or interest (unless in connection with the liquidation of the
related Mortgage Loan) or extend the Final Scheduled Maturity Date on the
Mortgage Loan. No costs incurred by the Master Servicer in respect of Servicing
Advances shall for the purposes of distributions to Noteholders or
Certificateholders be added to the amount owing under the related Mortgage Loan.

               (c) The Master Servicer, for the benefit of the Noteholders and
the Certificateholders, shall establish and maintain in the name of the Trustee
an Eligible Deposit Account (the "Collection Account"), bearing a designation
clearly indicating that the funds deposited therein are held for the benefit of
the Noteholders and the Certificateholders. The Collection Account shall
initially be established with the Trustee. The Master Servicer shall on the
Closing Date deposit into the Collection Account any amounts representing
payments on and any collections in respect of the Mortgage Loans received on or
after the Cut-off Date and prior to the Closing Date, and thereafter shall use
its best efforts to deposit within one Business Day, and shall in any event
deposit within _______ Business Days following receipt thereof the following
payments and collections received or made by it (without duplication) with
respect to the Mortgage Loans: (i) all payments received on and after the
Cut-off Date on account of principal on the Mortgage Loans and all full or
partial prepayments collected after the Cut-off Date; (ii) all payments received
on and after the Cut-off Date on account of interest on the Mortgage Loans;
(iii) all Net Liquidation Proceeds net of Foreclosure Profits; (iv) all
Insurance Proceeds; (v) all Released Mortgaged Property Proceeds; (vi) any
amounts payable in connection with the repurchase of any Mortgage Loan; and
(vii) any amount required to be deposited in the Collection Account pursuant to
Sections 3.5, 3.7, 3.15, 3.16 or 8.1; provided, however, that (x) with respect
to each Due Period, the Master Servicer shall be permitted to retain from
payments in respect of interest on the Mortgage Loans, the Servicing Fee for
such Due Period and (y) the Master Servicer shall be permitted to retain late
collections, including Liquidation Proceeds, Released Mortgaged Property
Proceeds and Insurance Proceeds, to the extent of any unpaid Servicing Fees,
unreimbursed Monthly Advances and/or Servicing Advances with respect to the
related Mortgage Loan. The foregoing requirements respecting deposits to the
Collection Account are exclusive, it being understood that, without limiting the
generality of the foregoing, the Master Servicer need not deposit in the
Collection Account amounts representing Foreclosure Profits, fees (including
annual fees), late charges or penalties payable by Mortgagors, or amounts
received by the Master Servicer for the accounts of Mortgagors for application
towards the payment of taxes, insurance premiums, assessments and similar items.

          SECTION 3.3. WITHDRAWALS FROM EACH COLLECTION ACCOUNT. The Trustee
shall withdraw or cause to be withdrawn funds from the Collection Account for
the following purposes with respect to the Mortgage Loans: (i) the deposits and
distributions required by Section 4.5(d); (ii) to the extent not retained by the
Master Servicer as provided in Section 3.2(c), to reimburse the Master Servicer
for any accrued unpaid Servicing Fees and for unreimbursed Monthly Advances and
Servicing Advances. The Master Servicer's right to reimbursement for unpaid
Servicing Fees and unreimbursed Servicing Advances shall be limited to late
collections on the related Mortgage Loan, including Liquidation Proceeds,
Released Mortgaged Property Proceeds, Insurance Proceeds and such other amounts
as may be collected by the Master Servicer from the related Mortgagor or
otherwise relating to the Mortgage Loan in respect of which such reimbursed
amounts are owed. If a Monthly Advance was made net of the Servicing Fee as
permitted by Section 3.15 hereof, no additional Servicing Fee for the related
Mortgage loan and Due Period shall be payable. The Master Servicer's right to
reimbursement from such Collection Account for unreimbursed Monthly Advances
shall be limited to late collections of interest on any Mortgage Loan and to
Liquidation Proceeds and Insurance Proceeds on related Mortgage Loans; (iii) to
withdraw any amount received from a Mortgagor that is recoverable and sought to
be recovered as a voidable preference by a trustee in bankruptcy pursuant to the
United States Bankruptcy Code in accordance with a final, nonappealable order of
a court having competent jurisdiction; (iv) (a) to make investments in Eligible
Investments and (b) to pay to the Master Servicer interest earned in respect of
Eligible Investments or on funds deposited in the Collection Account; (v) to
withdraw any funds deposited in such Collection Account that were not required
to be deposited therein (such as Servicing Compensation) or were deposited
therein in error and to pay such funds to the appropriate Person; (vi) to pay
the Master Servicer Servicing Compensation pursuant to Section 3.9 hereof to the
extent not retained or paid pursuant to Section 3.2(c); (vii) to withdraw funds
necessary for the conservation and disposition of REO Property pursuant to
Section 3.7; and (viii) to clear and terminate such Collection Account upon the
termination of this Agreement and to pay any amounts remaining therein in
accordance with Section 8.1(b).

          SECTION 3.4. MAINTENANCE OF HAZARD INSURANCE; PROPERTY PROTECTION
EXPENSES. The Master Servicer shall cause to be maintained for each Mortgage
Loan fire and hazard insurance naming the Master Servicer as loss payee
thereunder providing extended coverage in an amount which is at least equal to
the lesser of (i) the maximum insurable value of the improvements securing such
Mortgage Loan from time to time, (ii) the combined principal balance owing on
such Mortgage Loan and any related First Lien and (iii) the minimum amount
required to compensate for damage or loss on a replacement cost basis. The
Master Servicer shall also maintain on property acquired upon foreclosure, or by
deed in-lieu of foreclosure, hazard insurance with extended coverage in an
amount which is at least equal to the lesser of (i) the maximum insurable value
from time to time of the improvements which are a part of such property, (ii)
the combined principal balance owing on such Mortgage Loan and any related First
Lien and (iii) the minimum amount required to compensate for damage or loss on a
replacement cost basis at the time of such foreclosure, fire and or deed in lieu
of foreclosure plus accrued interest and the good-faith estimate of the Master
Servicer of related Servicing Advances to be incurred in connection therewith.
Amounts collected by the Master Servicer under any such policies shall be
deposited in the Collection Account to the extent called for by Section 3.2. In
cases in which any Mortgaged Property is located in a federally designated flood
area, the hazard insurance to be maintained for the related Mortgage Loan shall
include flood insurance to the extent such flood insurance is available and the
Master Servicer has determined such insurance to be necessary in accordance with
accepted mortgage loan servicing standards for mortgage loans comparable to the
Mortgage Loans. All such flood insurance shall be in amounts equal to the least
of the amount in clause (i) above, clause (ii) above and the maximum amount of
insurance available under the National Flood Insurance Act of 1968, as amended.
The Master Servicer shall be under no obligation to require that any Mortgagor
maintain earthquake or other additional insurance and shall be under no
obligation itself to maintain any such additional insurance on property acquired
in respect of a Mortgage Loan, other than pursuant to such applicable laws and
regulations as shall at any time be in force and as shall require such
additional insurance.

          SECTION 3.5. MAINTENANCE OF MORTGAGE IMPAIRMENT INSURANCE POLICY. In
the event that the Master Servicer shall obtain and maintain a blanket policy
with an insurer having a General Policy rating of A:VIII or better in Best's Key
Rating Guide insuring against fire and hazards of extended coverage on all of
the Mortgage Loans, then, to the extent such policy names the Master Servicer as
loss payee and provides coverage in an amount equal to the aggregate unpaid
principal balance on the Mortgage Loans without co-insurance, and otherwise
complies with the requirements of Section 3.4, the Master Servicer shall be
deemed conclusively to have satisfied its obligations with respect to fire and
hazard insurance coverage under Section 3.4, it being understood and agreed that
such blanket policy may contain a deductible clause, in which case the Master
Servicer shall, in the event that there shall not have been maintained on the
related Mortgaged Property a policy complying with Section 3.4, and there shall
have been a loss which would have been covered by such policy, deposit in the
Collection Account the difference, if any, between the amount that would have
been payable under a policy complying with Section 3.4 and the amount paid under
such blanket policy. Upon the request of the Owner Trustee or the Trustee, the
Master Servicer shall cause to be delivered to the Owner Trustee or the Trustee
a certified true copy of such policy. In connection with its activities as
administrator and servicer of the Mortgage Loans, the Master Servicer agrees to
prepare and present, on behalf of itself, the Owner Trustee, the Trustee, the
Noteholders and the Certificateholders, claims under any such policy in a timely
fashion in accordance with the terms of such policy.

          SECTION 3.6. FIDELITY BOND. The Master Servicer shall maintain with a
responsible company, and at its own expense, a blanket fidelity bond and an
errors and omissions insurance policy, in a minimum amount acceptable to Fannie
Mae or Freddie Mac or otherwise in an amount as is commercially available at a
cost that is not generally regarded as excessive by industry standards, with
broad coverage on all officers, employees or other persons acting in any
capacity requiring such persons to handle funds, money, documents or papers
relating to the Mortgage Loans ("Master Servicer Employees"). Any such fidelity
bond and errors and omissions insurance shall protect and insure the Master
Servicer against losses, including losses resulting from forgery, theft,
embezzlement, fraud, errors and omissions and negligent acts of such Master
Servicer Employees. Such fidelity bond shall also protect and insure the Master
Servicer against losses in connection with the release or satisfaction of a
Mortgage Loan without having obtained payment in full of the indebtedness
secured thereby. No provision of this Section 3.6 requiring such fidelity bond
and errors and omissions insurance shall diminish or relieve the Master Servicer
from its duties and obligations as set forth in this Agreement. Upon the request
of the Owner Trustee or the Trustee, the Master Servicer shall cause to be
delivered to the Owner Trustee or the Trustee a certified true copy of such
fidelity bond and insurance policy.

          SECTION 3.7. MANAGEMENT AND REALIZATION UPON DEFAULTED MORTGAGE LOANs.
On behalf of the Issuer, the Master Servicer shall manage, conserve, protect and
operate each REO Property for the Noteholders and the Certificateholders solely
for the purpose of its prudent and prompt disposition and sale. The Master
Servicer shall, either itself or through an agent selected by the Master
Servicer, manage, conserve, protect and operate the REO Property in the same
manner that it manages, conserves, protects and operates other foreclosed
property for its own account, and in the same manner that similar property in
the same locality as the REO Property is managed. The Master Servicer shall
attempt to sell the same (and may temporarily rent the same) on such terms and
conditions as the Master Servicer deems to be in the best interests of the
Noteholders and the Certificateholders. The Master Servicer shall cause to be
deposited, no later than ________ Business Days after the receipt thereof, in
the Collection Account, all revenues received with respect to the related REO
Property and shall retain, or cause the Trustee to withdraw therefrom funds
necessary for the proper operation, management and maintenance of the REO
Property and the fees of any managing agent acting on behalf of the Master
Servicer. The disposition of REO Property shall be carried out by the Master
Servicer for cash at such price, and upon such terms and conditions, as the
Master Servicer deems to be in the best interests of the Noteholders and the
Certificateholders and, as soon as practicable thereafter, the expenses of such
sale shall be paid. The cash proceeds of sale of the REO Property shall be
promptly deposited in the Collection Account, net of Foreclosure Profits and of
any related unreimbursed Servicing Advances, accrued and unpaid Servicing Fees
and unreimbursed Monthly Advances payable to the Master Servicer in accordance
with Section 3.3, for distribution to the Noteholders and the Certificateholders
in accordance with Section 4.5 hereof. The Master Servicer shall foreclose upon
or otherwise comparably convert to ownership Mortgaged Properties securing such
of the Mortgage Loans as come into and continue in default when no satisfactory
arrangements can be made for collection of delinquent payments pursuant to
Section 3.2. In the event that title to any Mortgaged Property is acquired in
foreclosure or by deed in lieu of foreclosure, the deed or certificate of sale
shall be issued to the Owner Trustee, or to its nominee on behalf of the
Noteholders and the Certificateholders.

          SECTION 3.8. TRUSTEE TO COOPERATE. Upon payment in full of any
Mortgage Loan, the Master Servicer is authorized to execute, pursuant to the
authorization contained in Section 3.1, if the related Assignment of Mortgage
has been recorded as required hereunder, an instrument of satisfaction regarding
the related Mortgage, which instrument of satisfaction shall be recorded by the
Master Servicer if required by applicable law and be delivered to the Person
entitled thereto. It is understood and agreed that no expenses incurred in
connection with such instrument of satisfaction or transfer shall be reimbursed
from amounts deposited in the Collection Account. If the Trustee is holding the
Mortgage Files, from time to time and as appropriate for the servicing or
foreclosure of any Mortgage Loan, the Trustee shall, upon request of the Master
Servicer and delivery to the Trustee of a Request for Release, in the form
approved by the Trustee signed by a Servicing Officer, release the related
Mortgage File to the Master Servicer, and the Trustee shall execute such
documents, in the forms provided by the Master Servicer, as shall be necessary
to the prosecution of any such proceedings or the taking of other servicing
actions. Such Request for Release shall obligate the Master Servicer to return
the Mortgage File to the Trustee when the need therefor by the Master Servicer
no longer exists unless the Mortgage Loan shall be liquidated, in which case,
upon receipt of a certificate of a Servicing Officer similar to that hereinabove
specified, the Request for Release shall be released by the Trustee to the
Master Servicer. In order to facilitate the foreclosure of the Mortgage securing
any Mortgage Loan that is in default following recordation of the related
Assignment of Mortgage in accordance with the provisions hereof, the Trustee
shall, if so requested in writing by the Master Servicer, execute an appropriate
assignment in the form provided to the Trustee by the Master Servicer to assign
such Mortgage Loan for the purpose of collection to the Master Servicer (any
such assignment shall unambiguously indicate that the assignment is for the
purpose of collection only), and, upon such assignment, such assignee for
collection will thereupon bring all required actions in its own name and
otherwise enforce the terms of the Mortgage Loan and deposit or credit the Net
Liquidation Proceeds, exclusive of Foreclosure Profits, received with respect
thereto in the Collection Account. In the event that all delinquent payments due
under any such Mortgage Loan are paid by the Mortgagor and any other defaults
are cured then the assignee for collection shall promptly reassign such Mortgage
Loan to the Trustee and return it to the place where the related Mortgage File
was being maintained.

          SECTION 3.9. SERVICING FEE. The servicing fee for a Distribution Date
shall equal the product of (a) one-twelfth, (b) the Servicing Fee Rate and (c)
the Pool Balance as of the first day of the preceding Due Period (the "Servicing
Fee"). The Master Servicer shall also be entitled to all late payment charges
and other administrative fees or similar charges, including without limitation,
Foreclosure Profits, allowed by applicable law with respect to Mortgage Loans,
collected (from whatever source) on the Mortgage Loans (the "Supplemental
Servicing Fee"). The Master Servicer also shall be entitled to and may retain
from Collections the Servicing Fee, as provided herein. The Master Servicer, in
its discretion at its election, may defer receipt of all or any portion of the
Servicing Fee or Supplemental Servicing Fee for any Due Period to and until a
later Due Period for any reason, including in order to avoid a shortfall in any
payments due on any Notes or Certificates. Any such deferred amount shall be
payable to (or may be retained from subsequent collections by) the Master
Servicer on demand.

          SECTION 3.10. MASTER SERVICER'S CERTIFICATE. On each Determination
Date, the Master Servicer shall deliver to the Owner Trustee, the Trustee and
the Seller, with a copy to the Rating Agencies, a Master Servicer's Certificate
containing all information necessary to make the distributions pursuant to
Sections 4.5 and 4.6 for the Due Period preceding the date of such Master
Servicer's Certificate. Mortgage Loans to be purchased by the Master Servicer or
to be repurchased by the Seller shall be identified by the Master Servicer by
account number with respect to such Mortgage Loan (as specified in Exhibit A).

          SECTION 3.11 ANNUAL STATEMENT AS TO COMPLIANCE; NOTICE OF DEFAULT. (a)
The Master Servicer shall deliver to the Owner Trustee and the Trustee, on or
before of each year beginning _________, 200__, an Officers' Certificate, dated
as of December 31 of the preceding year, stating that (i) a review of the
activities of the Master Servicer during the preceding twelve-month period (or,
in the case of the first such report, during the period from the Closing Date to
December 31, 200__) and of its performance under this Agreement has been made
under such officers' supervision and (ii) to the best of such officers'
knowledge, based on such review, the Master Servicer has fulfilled all its
obligations under this Agreement throughout such year or, if there has been a
default in the fulfillment of any such obligation, specifying each such default
known to such officers and the nature and status thereof. The Trustee shall send
a copy of such certificate and the report referred to in Section 3.10 to the
Rating Agencies. A copy of such certificate and the report referred to in
Section 3.10 may be obtained by any Certificateholder by a request in writing to
the Owner Trustee addressed to the Corporate Trust Office (as defined in the
Trust Agreement) or by any Noteholder by a request in writing to the Trustee
addressed to the Corporate Trust Office. Upon the telephone request of the Owner
Trustee, the Trustee will promptly furnish the Owner Trustee a list of
Noteholders as of the date specified by the Owner Trustee.

               (b) The Master Servicer shall deliver to the Owner Trustee, the
Trustee and the Rating Agencies, promptly after having obtained knowledge
thereof, but in no event later than _____ Business Days thereafter, written
notice in an Officers' Certificate of any event which with the giving of notice
or lapse of time, or both, would become a Servicer Default under Section 7.1(a)
or (b).

          SECTION 3.12. ANNUAL INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS' REPORT.
The Master Servicer shall cause a firm of independent certified public
accountants, which may also render other services to the Master Servicer or the
Seller, to deliver to the Seller, the Owner Trustee and the Trustee on or before
of each year beginning __________, 200__, a letter addressed to the Master
Servicer, the Seller, the Owner Trustee and the Trustee and each Rating Agency,
to the effect that such firm has with respect to the Master Servicer's overall
servicing operations examined such operations in accordance with the
requirements of the Uniform Single Audit Program for Mortgage Bankers during the
preceding calendar year (or, in the case of the first such report, during the
period from the Closing Date to December 31, 200__), and stating such firm's
conclusions relating thereto. Such report will also indicate that the firm is
independent of the Master Servicer within the meaning of the Code of
Professional Ethics of the American Institute of Certified Public Accountants.

          SECTION 3.13. ACCESS TO CERTAIN DOCUMENTATION AND INFORMATION
REGARDING MORTGAGE LOANS. The Master Servicer shall provide to the
Certificateholders and Noteholders access to the Mortgage Files in such cases
where the Certificateholders or Noteholders shall be required by applicable
statutes or regulations to review such documentation as demonstrated by evidence
satisfactory to the Master Servicer in its reasonable judgment. Access shall be
afforded without charge, but only upon reasonable request and during the normal
business hours at the respective offices of the Master Servicer. Nothing in this
Section 3.13 shall affect the obligation of the Master Servicer to observe any
applicable law prohibiting disclosure of information regarding the Mortgagors
and the failure of the Master Servicer to provide access to information as
provided in this Section 3.13 as a result of such obligation shall not
constitute a breach of this Section 3.13.

          SECTION 3.14. MASTER SERVICER EXPENSES. The Master Servicer shall be
required to pay all expenses incurred by it in connection with its activities
hereunder, including fees and disbursements of independent accountants, taxes
imposed on the Master Servicer and expenses incurred in connection with
distributions and reports to Certificateholders and Noteholders.

          SECTION 3.15. ADVANCES BY THE MASTER SERVICER. (a) Not later than the
close of business on the _______ Business Day preceding each Distribution Date,
the Master Servicer shall remit to the Trustee for deposit in the Collection
Account an amount, to be distributed on the related Distribution Date pursuant
to Section 4.5(d), equal to the sum of (a) the interest accrued on each Mortgage
Loan at the Mortgage Rate (or at such lower rate as may be in effect for such
Mortgage Loan pursuant to application of the Civil Relief Act and/or any Debt
Service Reduction) through the related Due Date, but not received as of the
close of business on the Determination Date for such Distribution Date (net of
the Servicing Fee) and (b) with respect to each REO Property which was acquired
during or prior to the related Due Period and as to which a final disposition
did not occur during the related Due Period, an amount equal to the excess, if
any, of interest on the Principal Balance of such REO Property at the Net Rate
for the most recently ended Due Period prior to the related Determination Date
for the related Mortgage Loan over the net income from the REO Property
transferred to the Collection Account for such Distribution Date pursuant to
Section 3.4; such sum being defined herein as the "Monthly Advance." The Master
Servicer may fund all or a portion of the Monthly Advance with respect to the
Mortgage Loans by instructing the Trustee on such Determination Date to use
funds deposited in the Collection Account which are not part of the Total
Distribution Amount for the related Distribution Date; provided that if such
funds are so used the Master Servicer shall replace such funds on or before any
subsequent Determination Date on which such funds are required to be part of the
Total Distribution Amount.

               (b) Notwithstanding anything herein to the contrary, no Servicing
Advance or Monthly Advance shall be required to be made hereunder if the Master
Servicer determines that such Servicing Advance or Monthly Advance would, if
made, constitute a Nonrecoverable Advance.

          SECTION 3.16. OPTIONAL PURCHASE OF DEFAULTED MORTGAGE LOANS. The
Master Servicer, in its sole discretion, shall have the right to elect (by
written notice sent to the Seller, the Owner Trustee and the Trustee) to
purchase for its own account from the Issuer any Mortgage Loan which is 90 days
or more delinquent in the manner and at the price specified in Section 2.2. The
Purchase Price for any Mortgage Loan purchased hereunder shall be deposited in
the Collection Account and the Trustee, upon receipt of such deposit, shall
release or cause to be released to the Master Servicer or its designee the
related Mortgage File and shall execute and deliver such instruments of transfer
or assignment prepared by the purchaser of such Mortgage Loan, in each case
without recourse, as shall be necessary to vest in the purchaser of such
Mortgage Loan any Mortgage Loan released pursuant hereto and the purchaser of
such Mortgage Loan shall succeed to all the Issuer's right, title and interest
in and to such Mortgage Loan and all security and documents related thereto.
Such assignment shall be an assignment outright and not for security. The
purchaser of such Mortgage Loan shall thereupon own such Mortgage Loan, and all
security and documents, free of any further obligation to the Owner Trustee, the
Trustee, the Noteholders or the Certificateholders with respect thereto.

          SECTION 3.17. SUPERIOR LIENS. The Master Servicer shall file (or cause
to be filed) of record a request for notice of any action by a superior
lienholder under a First Lien for the protection of the Issuer's interest, where
permitted by local law and whenever applicable state law does not require that a
junior lienholder be named as a party defendant in foreclosure proceedings in
order to foreclose such junior lienholder's equity of redemption. If the Master
Servicer is notified that any superior lienholder has accelerated or intends to
accelerate the obligations secured by the First Lien, or has declared or intends
to declare a default under the mortgage or the promissory note secured thereby,
or has filed or intends to file an election to have the Mortgaged Property sold
or foreclosed, the Master Servicer shall take, on behalf of the Trust, whatever
actions are necessary to protect the interests of the Noteholders and the
Certificateholders, and/or to preserve the security of the related Mortgage
Loan. The Master Servicer shall advance the necessary funds to cure the default
or reinstate the superior lien, if the Master Servicer reasonably believes such
advance is in the best interests of the Noteholders and the Certificateholders.
The Master Servicer shall not make such an advance except to the extent that it
determines in its reasonable good faith judgment that the advance would be
recoverable from Liquidation Proceeds on the related Mortgage Loan.

          SECTION 3.18. PAYMENT OF TAXES, INSURANCE AND OTHER CHARGES. With
respect to each Mortgage Loan, the Master Servicer shall maintain accurate
records reflecting fire and hazard insurance coverage. With respect to each
Mortgage Loan as to which the Master Servicer maintains escrow accounts, the
Master Servicer shall maintain accurate records reflecting the status of ground
rents, taxes, assessments, water rates and other charges which are or may become
a lien upon the Mortgaged Property and the status of primary mortgage guaranty
insurance premiums, if any, and fire and hazard insurance coverage and shall
obtain, from time to time, all bills for the payment of such charges (including
renewal premiums) and shall effect payment thereof prior to the applicable
penalty or termination date and at a time appropriate for securing maximum
discounts allowable, employing for such purpose deposits of the Mortgagor in any
escrow account which shall have been estimated and accumulated by the Master
Servicer in amounts sufficient for such purposes, as allowed under the terms of
the Mortgage. To the extent that a Mortgage does not provide for escrow
payments, the Master Servicer shall, if it has received notice of a default or
deficiency, monitor such payments to determine if they are made by the
Mortgagor.

          SECTION 3.19. APPOINTMENT OF SUB-SERVICER. The Master Servicer may at
any time appoint a sub-servicer to perform all or any portion of its obligations
as Master Servicer hereunder; provided, however, that the Rating Agency
Condition shall have been satisfied in connection therewith; provided further
that the Master Servicer shall remain obligated and be liable to the Issuer, the
Owner Trustee, the Trustee, the Certificateholders and the Noteholders for the
servicing and administering of the Mortgage Loans in accordance with the
provisions hereof without diminution of such obligation and liability by virtue
of the appointment of such sub-servicer and to the same extent and under the
same terms and conditions as if the Master Servicer alone were servicing and
administering the Mortgage Loans. The fees and expenses of the sub-servicer
shall be as agreed between the Master Servicer and its sub-servicer from time to
time and none of the Issuer, the Owner Trustee, the Trustee, the
Certificateholders or the Noteholders shall have any responsibility therefor.

                                   ARTICLE IV

                  Distributions; Reserve Account; Statements to
                       Certificateholders and Noteholders

          SECTION 4.1. ESTABLISHMENT OF TRUST ACCOUNTS. (a) (i) The Master
Servicer, for the benefit of the Noteholders, shall establish and maintain in
the name of the Trustee an Eligible Deposit Account (the "Note Distribution
Account"), bearing a designation clearly indicating that the funds deposited
therein are held for the benefit of the Noteholders. The Note Distribution
Account shall initially be established with the Trustee.

                    (ii) The Master Servicer, for the benefit of the Noteholders
and the Certificateholders, shall establish and maintain in the name of the
Trustee an Eligible Deposit Account (the "Reserve Account"), bearing a
designation clearly indicating that the funds deposited therein are held for the
benefit of the Noteholders and the Certificateholders. The Reserve Account shall
be maintained with the Trustee as long as the Trustee is an Eligible
Institution.

               (b) Funds on deposit in the Collection Account, the Note
Distribution Account and the Reserve Account (collectively, the "Trust
Accounts") and the Certificate Distribution Account shall be invested by the
Trustee with respect to Trust Accounts and by the Owner Trustee with respect to
the Certificate Distribution Account (or any custodian with respect to funds on
deposit in any such account) in Eligible Investments selected in writing by the
Master Servicer (pursuant to standing instructions or otherwise); provided,
however, it is understood and agreed that neither the Trustee nor the Owner
Trustee shall be liable for any loss arising from such investment in Eligible
Investments. All such Eligible Investments shall be held by or on behalf of the
Trustee or the Owner Trustee, as applicable, for the benefit of the Noteholders

agreement, where the final determination that any such cost, expense, loss,
claim, damage or liability arose out of, or was imposed upon any such Person
through, any such negligence, willful misfeasance, bad faith or recklessness on
the part of the Master Servicer or any sub-servicer, is established by a court
of law, by an arbitrator or by way of settlement agreed to by the Master
Servicer. Notwithstanding the foregoing, if the Master Servicer is rendered
unable, in whole or in part, by virtue of an act of God, act of war, fires,
earthquake or other natural disasters, to satisfy its obligations under this
Agreement, the Master Servicer shall not be deemed to have breached any such
obligation upon the sending of written notice of such event to the other parties
hereto, for so long as the Master Servicer remains unable to perform such
obligation as a result of such event. This provision shall not be construed to
limit the Master Servicer's or any other party's rights, obligations,
liabilities, claims or defenses which arise as a matter of law or pursuant to
any other provision of this Agreement. The Master Servicer shall indemnify,
defend and hold harmless the Issuer, the Owner Trustee, the Trustee, the Seller,
the Certificateholders and the Noteholders or any of the officers, directors,
employees and agents of the Issuer, the Owner Trustee, the Trustee or the Seller

or imposed upon any such Person as a result of any compensation payable to any
sub-servicer (including any fees payable in connection with the termination of
the servicing activities of such sub-servicer with respect to any Mortgage Loan)
whether pursuant to the terms of any sub-servicing agreement or otherwise.

OBLIGATIONS OF, MASTER SERVICER. Any Person (a) into which the Master Servicer
may be merged or consolidated, (b) which may result from any merger or
consolidation to which the Master Servicer shall be a party or (c) which may
succeed to the properties and assets of the Master Servicer, substantially as a
whole, shall be the successor to the Master Servicer without the execution or
filing of any document or any further act by any of the parties to this
Agreement; provided, however, that the Master Servicer hereby covenants that it
will not consummate any of the foregoing transactions except upon satisfaction
of the following: (i) the surviving Master Servicer (if other than
_____________) executes an agreement of assumption to perform every obligation
of the Master Servicer under this Agreement, (ii) immediately after giving
effect to such transaction, no representation or warranty made pursuant to
Section 6.1 shall have been breached and no Servicer Default, and no event that,
after notice or lapse of time, or both, would become a Servicer Default shall
have occurred and be continuing, (iii) the Master Servicer shall have delivered
to the Owner Trustee and the Trustee an Officers' Certificate and an Opinion of
Counsel each stating that such consolidation, merger or succession and such

precedent, if any, provided for in this Agreement relating to such transaction
have been complied with, and that the Rating Agency Condition shall have been
satisfied with respect to such transaction, (iv) the surviving Master Servicer
shall have a consolidated net worth at least equal to that of the predecessor
Master Servicer, and (v) such transaction will not result in a material adverse
federal or state tax consequence to the Issuer, the Noteholders or the

agents shall be under any liability to the Issuer, the Noteholders or the
Certificateholders, except as provided under this Agreement, for any action
taken or for refraining from the taking of any action by the Master Servicer or
any sub-servicer pursuant to this Agreement or for errors in judgment; provided,
however, that this provision shall not protect the Master Servicer or any such
person against any liability that would otherwise be imposed by reason of
willful misfeasance, bad faith or negligence in the performance of duties or by
reason of reckless disregard of obligations and duties under this Agreement. The
Master Servicer or any sub-servicer and any of their respective directors,
officers, employees or agents may rely in good faith on any document of any kind
prima facie properly executed and submitted by any Person respecting any matters
arising under this Agreement. Except as provided in this Agreement the Master
Servicer shall not be under any obligation to appear in, prosecute or defend any
legal action that shall be incidental to its duties to service the Mortgage
Loans in accordance with this Agreement, and that in its opinion may involve it
in any expense or liability; provided, however, that the Master Servicer, may
(but shall not be required to) undertake any reasonable action that it may deem
necessary or desirable in respect of the Basic Documents to protect the
interests of the Certificateholders under this Agreement and the Noteholders
under the Indenture.

          SECTION 6.5. NOT TO RESIGN AS MASTER SERVICER. Subject to the

responsibilities and obligations of the resigning Master Servicer in accordance
with Section 7.2 or the date upon which any regulatory authority requires such
resignation.

commence, and will diligently pursue, all reasonable efforts to remedy such
default); or (c) any failure of the Master Servicer to pay any Monthly Advance
required to be made from its own funds pursuant to Section 3.15 that continues

not less than a majority of the Current Principal Amount of the Notes (or the
Holders (as defined in the Trust Agreement) of Certificates evidencing not less

writing any default by the Master Servicer in the performance of its obligations
hereunder and its consequences, except a default in making any required deposits
to or payments from any of the Trust Accounts in accordance with this Agreement.

any Servicer Default arising therefrom shall be deemed to have been remedied for
every purpose of this Agreement. No such waiver shall extend to any subsequent
or other default or impair any right consequent thereto.

Distribution Date). Any Insolvency Proceeds remaining after the deposits
described above shall be paid to the GP Holder.

               (c) Notice of any termination of the Trust shall be given by the
Master Servicer to the Owner Trustee, the Trustee and the Rating Agencies as
soon as practicable after the Master Servicer has received notice thereof.
