capacities and on the terms and conditions set forth in this
Agreement;

     
NOW, THEREFORE, it is hereby agreed as follows:

     
1. Employment.

     
(a) Agreement to Employ. Upon the

commencing on April 26, 2004 (the “Commencement
Date”), unless earlier terminated in accordance with the
provisions hereof. The employment period shall automatically be
extended for an indefinite number of one-year periods, subject
to earlier termination in accordance with the provisions hereof,
unless notice is given by either party of an intent not to

(2) months prior to the expiration of the then current
employment period. The period during which the Executive is
employed pursuant to this Agreement, including any extension
thereof in accordance with this Paragraph 1(b), shall be

available by the Company to all employees or to other executive
officers of the Company in the same class as the Executive.
Participation in any such plan or program shall be subject to
the terms and conditions of such plan, including any waiting
periods and/or eligibility requirements thereunder

     
6. Reimbursement of Expenses. During
the Employment Period, the Executive shall be entitled to
receive prompt reimbursement for all reasonable expenses
incurred by her in performing services hereunder, in accordance
with the Company’s policies and procedures established for
reimbursement of expenses of executive officers in the same
class as the Executive. Reimbursement shall be subject to prompt
presentation by Executive of expense statements, receipts or
such other supporting information as the Company may require or
as may be required for tax purposes. The Company will also
reimburse the Executive for COBRA expenses.

     
7. Termination of Employment.

     
(a) Termination of the Employment Period.
Notwithstanding Paragraph 1(b), the Company reserves
the right at any time during the Employment Period to terminate
Executive’s employment with or without Cause. The
Employment Period shall end upon the earliest to occur of
(i) Executive’s death or Disability (as defined
below), (ii) a termination of Executive’s employment
by the Company for Cause (as defined below), (iii) a
termination of Executive’s employment by the Company
without Cause, (iv) a resignation by the Executive, or
(v) the end of the final Employment Period after notice of
nonrenewal pursuant to Paragraph 1(b) herein.

     
(b) Benefits Payable Upon Termination.
(i) In the event of the termination of Executive’s
employment on account of Executive’s death or Disability,
Executive’s voluntary resignation or the Company’s
termination of Executive’s employment for Cause, the
Company shall pay to Executive, or Executive’s estate on
account of her death, in a lump sum within 10 business days
following Executive’s termination, all earned but unpaid
then-existing Salary and Bonus; provided however, that, whether
any Bonus is earned at the time of Executive’s termination
will be determined by reference to the terms of the
Company’s respective bonus or performance-based
compensation plans or programs, if any, or, if not set forth
therein, as determined by the Company in its sole discretion
(such earned but unpaid Salary and Bonus hereafter referred to
as “Earned Compensation”). (ii) In the event of
the termination of Executive’s employment by the Company
without Cause, the Company shall (A) pay to Executive, in a
lump sum within 10 business days following such termination, all
Earned Compensation and (B) continue to pay
Executive’s then-existing Salary, in

2

 

accordance with the Company’s regular
payroll practices, (the “Severance Payments”) for the
twenty-six (26) weeks immediately following such
termination (the “Severance Period”).

     
(c) Notwithstanding anything herein to the
contrary, to the degree that a Bonus has been earned but cannot
be calculated because the performance objectives identified to
such Bonus cannot yet be calculated then payment of the earned
Bonus shall occur in a lump sum within 10 business days
following the date on which such performance goals are
calculated.

     
(d) Definitions. For the purposes of
this Agreement the following capitalized terms shall have the
following meanings:

		
	 	     
    (i) “Cause” shall mean any
    of the following: (A) fraud, personal dishonesty,
    embezzlement, defalcation or acts of gross negligence or gross
    misconduct on the part of Executive in the course of her
    employment; (B) a material breach of Executive’s
    fiduciary duty of loyalty to the Company; (C) a material
    breach of this Agreement by Executive that is injurious to the
    Company; (D) Executive’s conviction by a court of
    competent jurisdiction of, or pleading “guilty” or
    “no contest” to, (x) a felony, or (y) any
    other criminal charge (other than minor traffic violations)
    which could reasonably be expected to have, or which actually
    has, a material adverse financial impact on the Company or a
    material adverse impact on the Company’s reputation and
    standing in the community; (E) consistent drunkenness by
    Executive or her illegal use of narcotics which is, or could
    reasonably be expected to become, materially injurious to the
    reputation or business of the Company or which impairs, or could
    reasonably be expected to impair, the performance of
    Executive’s duties hereunder; (F) any breach of
    Paragraph 8 hereunder; or (G) willful failure by
    Executive to follow the lawful directions of the CEO.
    
	 
	 	     
    (ii) “Disability” shall
    mean Executive’s inability to perform the material duties
    required of her by the Company and historically performed by her
    due to a mental or physical illness or incapacity for a period
    of three consecutive months or for shorter periods aggregating
    four months during any twelve-month period.
    

     
(e) Full Discharge of Company
Obligations. The amounts payable to the Executive pursuant
to this Paragraph 7 following termination of her employment
shall be in full and complete satisfaction of the
Executive’s rights under this Agreement and any other
claims she may have in respect of her employment by the Company
or any of its subsidiaries. Such amounts shall constitute
liquidated damages with respect to any and all such rights and
claims and, upon the commencement of Executive’s receipt of
such amounts, and contingent on the full payment of such
amounts, the Company shall be released and discharged from any
and all liability to the Executive in connection with this
Agreement or otherwise in connection with the Executive’s
employment with the Company and its subsidiaries. Executive
agrees to enter into a release and waiver of claims agreement
satisfactory to the Company at the time of Executive’s
termination of employment in order to implement the purpose of
this Paragraph 7(e).

     
(f) Offset for Subsequent Employment.
In the event during the Severance Period the Executive
becomes employed with another entity (“Post Termination
Employment”), the Company’s obligation to make
Severance Payments shall be reduced on a dollar-for-dollar basis
by the amount that Executive earns on account of such Post
Termination Employment. The Executive agrees to notify the
Company of such Post Termination Employment and to disclose to
the Company the compensation to be earned by Executive therein.
In the event that the Executive fails to notify the Company of
such Post Termination Employment, within ten (10) business
days of the date Executive first undertakes such Post
Termination Employment, the Company’s obligation to make
Severance Payments shall expire.

     
8. Noncompetition and Confidentiality.
By and in consideration of the Noncompete Stipend and Salary
and other benefits to be provided by the Company hereunder, the
Executive agrees that:

		
	 	     
    (a) Noncompetition. During the
    Employment Period and during the six (6) month period
    following termination of the Executive’s employment for any
    reason (the “Restriction Period”), the Executive shall
    not, directly or indirectly, whether as a principal, partner,
    employee, agent, consultant, shareholder (other than shares
    purchased prior to the effective date of this Agreement or as a
    holder, or a member of a group which is a holder, of not in
    excess of five percent (5%) of the outstanding voting
    

3

 

		
	 	
    shares of any publicly traded company) or in any
    other relationship or capacity be affiliated with any business
    corporation, partnership, enterprise or entity in any geographic
    area, which competes with the Company’s Business (as
    defined below). For purposes of this Agreement, the
    “Company’s Business” at any time means the sale
    of party goods, including costumes, and any other line of
    business which the Company is engaged in or has substantial
    plans to become engaged in at the time.
    
	 
	 	     
    (b) Confidentiality. Unless
    specifically authorized in writing by the Company to do so,
    except to the extent required by an order of a court having
    competent jurisdiction or under subpoena from an appropriate
    government agency, the Executive shall not disclose (i) any
    information disclosed or made available to the Executive or
    known by the Executive as a direct or indirect consequence of or
    through employment by the Company, or (ii) any other
    information related to the Company’s referral sources,
    business practices, trade secrets, operating methods,
    techniques, products, processes, services or other operations
    (individually or collectively “Operations”),
    including, but not limited to, information relating to research,
    development, inventions, accounting, engineering or marketing of
    such Operations and including any such information of any third
    party which the Company is under an obligation to keep
    confidential (individually or collectively, “Confidential
    Information”) to any third person unless such Confidential
    Information has been previously disclosed to the public by the
    Company or is in the public domain (other than by reason of the
    Executive’s breach of this Paragraph 8(b)).
    
	 
	 	     
    (c) Nonsolicitation of Employees.
    During the Employment Period and the Restriction Period, the
    Executive shall not directly or indirectly solicit, encourage or
    induce any employee of the Company or any of its subsidiaries to
    terminate employment with such entity, and shall not directly or
    indirectly, either individually or as owner, agent, employee,
    consultant or otherwise, employ or offer employment to any
    person who is or was employed by the Company or a subsidiary
    thereof unless such person shall have ceased to be employed by
    such entity for a period of at least six months.
    
	 
	 	     
    (d) Company Property. Except as
    expressly provided herein, at the time of the Executive’s
    termination of employment or at any other time as the CEO or the
    Board may request, the Executive shall return to the Company all
    property of the Company, including any automobile and other
    machinery and all memoranda, notes, records, reports, manuals,
    drawings and blueprints, including electronic versions,
    concerning the Company’s Business (and all copies thereof)
    in the Executive’s possession or under her control.
    
	 
	 	     
    (e) Protection of Legitimate Business
    Interests. Executive acknowledges that
    (i) Executive’s position with the Company requires the
    performance of services which are special, unique and
    extraordinary in character and places him in a position of
    confidence and trust with the customers and employees of the
    Company, through which, among other things, she will obtain
    knowledge of the Company’s technical information and
    know-how and become acquainted with its customers, in which
    matters the Company has substantial proprietary interests,
    (ii) the restrictive covenants in this Paragraph 8 are
    necessary in order to protect and maintain such proprietary
    interests and other legitimate business interests of the
    Company, and (iii) the Company would not have entered into
    this Agreement unless such covenants were included herein.
    
	 
	 	     
    (f) Injunctive Relief and Other Remedies
    with Respect to Covenants. The Executive acknowledges and
    agrees that the covenants and obligations of the Executive with
    respect to noncompetition, nonsolicitation, confidentiality and
    Company property, relate to special, unique and extraordinary
    matters and that a violation of any of the terms of such
    covenants and obligations will cause the Company irreparable
    injury for which adequate remedies are not available at law.
    Therefore, the Executive agrees that the Company shall
    (i) be entitled to an injunction, restraining order or such
    other equitable relief (without the requirement to post bond)
    restraining the Executive from committing any violation of the
    covenants and obligations contained in this Paragraph 8 and
    (ii) have no further obligation to make any payments to the
    Executive hereunder following any material violation of the
    covenants and obligations contained in this Paragraph 8.
    These remedies are cumulative and are in addition to any other
    rights and remedies the Company may have at law or in equity. In
    connection with the foregoing provisions of this
    

4

 

		
	 	
    Paragraph 8, the Executive represents that
    her economic means and circumstances are such that such
    provisions will not prevent her from providing for herself and
    her family on a basis satisfactory to her.
    
	 
	 	     
    (g) Executive acknowledges that, any and all
    options to acquire Company stock granted to Executive during the
    course of Executive’s employment with the Company
    (“Options”) are and were granted in consideration for
    Executive’s covenants pursuant to subparagraphs 8(a),
    (b), (c) and (d) herein. In the event the Executive breaches any
    of the provisions of subparagraphs 8(a), (b), (c) or (d)
    herein, all Options (whether vested or not) then held by
    Executive shall expire and terminate immediately. For purposes
    of this Paragraph 8, the determination of any breach by the
    Executive of any provision of this Paragraph 8 shall be
    made by the Board of Directors of the Company in its sole
    discretion, and such determination shall be final and binding on
    the Company and Executive.
    
	 
	 	     
    (h) Non-Disparagement. Executive
    shall not at any time after the date hereof disparage the
    Company or any of its officers, directors, shareholders or any
    of their respective affiliates. The obligations of Executive
    under this Section 8(h) shall not apply to disclosures
    required by applicable law, regulation or order of a court or
    governmental agency.
    

     
9. Miscellaneous.

     
(a) Survival. Paragraphs 7 (relating
to early termination of employment), 8 (relating to
noncompetition, nonsolicitation and confidentiality and
non-disparagement), 9(c) (relating to arbitration), and 9(o)
(relating to governing law) shall survive the termination hereof.

     
(b) Validity and Enforceability. The
Executive acknowledges and agrees that the covenants set forth
in Paragraph 8 are reasonable and valid in geographical and
temporal scope and in all other respects. The invalidity or
unenforceability of any provision or provisions of this
Agreement shall not affect the validity or enforceability of any
other provision or provisions of this Agreement, which shall
remain in full force and effect. If any provision of this
Agreement is held to be invalid, void or unenforceable in any
jurisdiction, any court or arbitrator so holding shall
substitute a valid, enforceable provision that preserves, to the
maximum lawful extent, the terms and intent of such provisions
of this Agreement. If any of the provisions of, or covenants
contained in, this Agreement are hereafter construed to be
invalid or unenforceable in any jurisdiction, the same shall not
affect the remainder of the provisions or the enforceability
thereof in any other jurisdiction, which shall be given full
effect, without regard to the invalidity or unenforceability in
such other jurisdiction. Any such holding shall affect such
provision of this Agreement, solely as to that jurisdiction,
without rendering that or any other provision of this Agreement
invalid, illegal, or unenforceable in any other jurisdiction. If
any covenant should be deemed invalid, illegal or unenforceable
because its scope, either geographical or temporal, is
considered excessive, such covenant will be modified so that the
scope of the covenant is reduced only to the minimum extent
necessary to render the modified covenant valid, legal and
enforceable.

     
(c) Arbitration. Subject to
Paragraph 8(f), any dispute or controversy arising under or
in connection with this Agreement shall be resolved by binding
arbitration. The arbitration shall be held in Morris County, New
Jersey and except to the extent inconsistent with this
Agreement, shall be conducted in accordance with the Voluntary
Labor Arbitration Rules of the American Arbitration Association
then in effect at the time of the arbitration, and otherwise in
accordance with principles which would be applied by a court of
law or equity. The arbitrator shall be acceptable to both the
Company and the Executive. If the parties cannot agree on an
acceptable arbitrator, the dispute shall be heard by a panel of
three arbitrators, one appointed by each of the parties and the
third appointed by the other two arbitrators.

     
(d) Binding Effect. This Agreement
shall be binding on, and shall inure to the benefit of, the
Company and any person or entity that succeeds to the interest
of the Company (regardless of whether such succession does or
does not occur by operation of law) by reason of the sale of all
or a portion of the Company’s stock, a merger,
consolidation or reorganization involving the Company, or unless
the Company otherwise elects in writing, a sale of the assets of
the business of the Company (or portion thereof) in which the
Executive performs a majority of her services. This Agreement
shall also inure to the benefit of the Executive’s heirs,
executors, administrators and legal representatives.

5

 

     
(e) Assignment. This Agreement, and
the Executive’s rights and obligations hereunder, may not
be assigned by the Executive. The Company may assign its rights,
together with its obligations, hereunder in connection with any
sale, transfer or other disposition of all or substantially all
of the business assets with respect to which Executive is
performing a majority of her services at any such time.

     
(f) Entire Agreement. This Agreement
constitutes the entire agreement between the parties hereto with
respect to the matters referred to herein. No other agreement
relating to the terms of the Executive’s employment by the
Company, oral or otherwise, shall be binding between the parties
unless it is in writing and signed by the party against whom
enforcement is sought. There are no promises, representations,
inducements or statements between the parties relating to the
terms of Executive’s employment with the Company other than
those that are expressly contained herein. The Executive
acknowledges that she is entering into this Agreement of her own
free will and accord, and with no duress, that she has read this
Agreement and that she understands it and its legal consequences.

     
(g) Waiver. Waiver by any party
hereto of any breach or default by the other party of any of the
terms of this Agreement shall not operate as a waiver of any
other breach or default, whether similar to or different from
the breach or default waived. No waiver of any provision of this
Agreement shall be implied from any course of dealing between
the parties hereto or from any failure by either party hereto to
assert its or her rights hereunder on any occasion or series of
occasions.

     
(h) Notices. Any notice required or
desired to be delivered under this Agreement shall be in writing
and shall be delivered personally, by courier service, by

                                   ARTICLE II

      CONVEYANCE OF MORTGAGE LOANS; REPRESENTATIONS AND WARRANTIES

      SECTION 2.01. Conveyance of Mortgage Loans.

      The Depositor, concurrently with the execution and delivery hereof, does
hereby sell, transfer, assign, set over and convey to the Trustee without
recourse all the right, title and interest of the Depositor in and to the assets
of the Trust Fund. Such assignment includes all interest and principal received
on or with respect to the Mortgage Loans on or after the Cut-off Date (other
than Scheduled Payments due on the Mortgage Loans on or before the Cut-off
Date).

      In connection with such assignment, the Depositor does hereby deliver to,
and deposit with, the Trustee the following documents or instruments with
respect to each Mortgage Loan so assigned:

      (A)The Original Mortgage Note, together with all riders thereto, endorsed,
"Pay to the order of JPMorgan Chase Bank, as trustee - SURF 2004-BC3, without
recourse" together with all riders thereto. The Mortgage Note shall include all
intervening endorsements showing a complete chain of the title from the
originator to the Seller.

      (B)Except as provided below and for each Mortgage Loan that is not a MERS
Loan, the original recorded Mortgage together with all riders thereto, with
evidence of recording thereon, or, if the original Mortgage has not yet been
returned from the recording office, a copy of the original Mortgage together
with all riders thereto certified by the Seller to be true copy of the original
of the Mortgage that has been delivered for recording in the appropriate
recording office of the jurisdiction in which the Mortgaged Property is located
and in the case of each MERS Loan, the original Mortgage together with all
riders thereto, noting the presence of the MIN of the Loan and either language
indicating that the Mortgage Loan is a MOM Loan or if the Mortgage Loan was not
a MOM Loan at origination, the original Mortgage and the assignment thereof to
MERS, with evidence of recording indicated thereon, or a copy of the Mortgage
certified by the public recording office in which such Mortgage has been
recorded.

      (C)In the case of each Mortgage Loan that is not a MERS Loan, the original
Assignment of each Mortgage, to "JPMorgan Chase Bank, as trustee - SURF-BC3."

      (D)The original policy of title insurance (or a preliminary title report,
commitment or binder if the original title insurance policy has not been
received from the title insurance company).

                                       46
<PAGE>

      (E)Originals of any intervening assignments of the Mortgage, with evidence
of recording thereon or, if the original intervening assignment has not yet been
returned from the recording office, a copy of such assignment certified to be a
true copy of the original of the assignment which has been sent for recording in
the appropriate jurisdiction in which the Mortgaged Property is located.

      (F)Originals of all assumption and modification agreements, if any.

      If in connection with any Mortgage Loan, the Depositor cannot deliver the
Mortgage, Assignments of Mortgage or assumption, consolidation or modification,
as the case may be, with evidence of recording thereon, if applicable,
concurrently with the execution and delivery of this Agreement solely because of
a delay caused by the public recording office where such Mortgage, Assignments
of Mortgage or assumption, consolidation or modification, as the case may be,
has been delivered for recordation, the Depositor shall deliver or cause to be
delivered to the Trustee written notice stating that such Mortgage or
assumption, consolidation or modification, as the case may be, has been
delivered to the appropriate public recording office for recordation.
Thereafter, the Depositor shall deliver or cause to be delivered to the Trustee
such Mortgage, Assignments of Mortgage or assumption, consolidation or
modification, as the case may be, with evidence of recording indicated thereon,
if applicable, upon receipt thereof from the public recording office. To the
extent any required endorsement is not contained on a Mortgage Note or an
Assignment of Mortgage, the Depositor shall make or cause such endorsement to be
made.

      With respect to any Mortgage Loan, none of the Depositor, the Servicer or
the Trustee shall be obligated to cause to be recorded the Assignment of
Mortgage referred to in this Section 2.01. In the event that any Assignment of
Mortgage is not recorded or is improperly recorded, the Servicer shall have no
liability for its failure to receive or act on notices related to such
Assignment of Mortgage.

      The ownership of each Mortgage Note, the Mortgage and the contents of the
related Mortgage File is vested in the Trustee. Neither the Depositor nor the
Servicer shall take any action inconsistent with such ownership and shall not
claim any ownership interest therein. The Depositor and the Servicer shall
respond to any third party inquiries with respect to ownership of the Mortgage
Loans by stating that such ownership is held by the Trustee on behalf of the
Certificateholders. Mortgage documents relating to the Mortgage Loans not
delivered to the Trustee are and shall be held in trust by the Servicer, for the
benefit of the Trustee as the owner thereof, and the Servicer's possession of
the contents of each Mortgage File so retained is for the sole purpose of
servicing the related Mortgage Loan, and such retention and possession by the
Servicer is in a custodial capacity only. The Depositor agrees to take no action
inconsistent with the Trustee's ownership of the Mortgage Loans, to promptly
indicate to all inquiring parties that the Mortgage Loans have been sold and to
claim no ownership interest in the Mortgage Loans.

      It is the intention of this Agreement that the conveyance of the
Depositor's right, title and interest in and to the Trust Fund pursuant to this
Agreement shall constitute a purchase and sale and not a loan. If a conveyance
of Mortgage Loans from the Seller to the Depositor is characterized as a pledge
and not a sale, then the Depositor shall be deemed to have transferred to the
Trustee all of the Depositor's right, title and interest in, to and under the
obligations of the Seller deemed to be secured by said pledge; and it is the
intention of this Agreement that the Depositor shall also be deemed to have
granted to the Trustee a first priority security interest in all of the
Depositor's right, title, and interest in, to and under the obligations of the
Seller to the Depositor deemed to be secured by said pledge and that the Trustee
shall be deemed to be an independent custodian for purposes of perfection of the
security interest granted to the Depositor. If the conveyance of the Mortgage
Loans from the Depositor to the Trustee is characterized as a pledge, it is the
intention of this Agreement that this Agreement shall constitute a security
agreement under applicable law, and that the Depositor shall be deemed to have
granted to the Trustee a first priority security interest

                                       47
<PAGE>

in all of the Depositor's right, title and interest in, to and under the
Mortgage Loans, all payments of principal of or interest on such Mortgage Loans,
all other rights relating to and payments made in respect of the Trust Fund, and
all proceeds of any thereof. If the trust created by this Agreement terminates
prior to the satisfaction of the claims of any Person in any Certificates, the
security interest created hereby shall continue in full force and effect and the
Trustee shall be deemed to be the collateral agent for the benefit of such
Person.

      In addition to the conveyance made in the first paragraph of this Section
2.01, the Depositor does hereby convey, assign and set over to the Trustee for
the benefit of the Certificateholders its rights and interests under the Sale
Agreement, including the Depositor's right, title and interest in the
representations and warranties contained in the Sale Agreement and the benefit
of the repurchase obligations and the obligation of the Seller contained in the
Sale Agreement to take, at the request of the Depositor or the Trustee, all
action on its part which is reasonably necessary to ensure the enforceability of
a Mortgage Loan. The Trustee hereby accepts such assignment, and shall be
entitled to exercise all rights of the Depositor under the Sale Agreement as if,
for such purpose, it were the Depositor. The foregoing sale, transfer,
assignment, set-over, deposit and conveyance does not and is not intended to
result in creation or assumption by the Trustee of any obligation of the
Depositor, the Seller, or any other Person in connection with the Mortgage Loans
or any other agreement or instrument relating thereto.

      SECTION 2.02. Acceptance by Trustee of the Mortgage Loans.

      Except as set forth in the Exception Report delivered contemporaneously
herewith (the "Exception Report"), the Trustee acknowledges receipt of the
Mortgage Note for each Mortgage Loan and delivery of a Mortgage File (but does
not acknowledge receipt of all documents required to be included in such
Mortgage File) with respect to each Mortgage Loan and declares that it holds and
will hold such documents and any other documents constituting a part of the
Mortgage Files delivered to it in trust for the use and benefit of all present
and future Certificateholders. The Depositor will cause the Seller to repurchase
any Mortgage Loan to which a material exception was taken in the Exception
Report unless such exception is cured to the satisfaction of the Trustee within
45 Business Days of the Closing Date.

      The Trustee acknowledges receipt of the three Cap Contracts (forms of
which are attached hereto as Exhibit O-1, Exhibit O-2 and Exhibit O-3), Transfer
Agreement and the Sale Agreement.

      The Trustee agrees, for the benefit of Certificateholders and the NIM
Insurer, to review each Mortgage File delivered to it within 60 days after the
Closing Date to ascertain and to certify, within 70 days of the Closing Date, to
the NIM Insurer, the Depositor and the Servicer that all documents required by
Section 2.01 have been executed and received, and that such documents relate to
the Mortgage Loans identified in Exhibit B that have been conveyed to it. If the
Trustee finds any document or documents constituting a part of a Mortgage File
to be missing or defective (that is, mutilated, damaged, defaced or unexecuted)
in any material respect, the Trustee shall promptly (and in any event within no
more than five Business Days) after such finding so notify the Servicer, the
Seller, the Depositor and the NIM Insurer. In addition, the Trustee shall also
notify the Servicer, the Seller, the Depositor and the NIM Insurer, if the
original Mortgage with evidence of recording thereon with respect to a Mortgage
Loan is not received within 70 days of the Closing Date; if it has not been
received because of a delay caused by the public recording office where such
Mortgage has been delivered for recordation, the Depositor shall deliver or
cause to be delivered to the Trustee written notice stating that such Mortgage
has been delivered to the appropriate public recording officer for recordation
and thereafter the Depositor shall deliver or cause to be delivered such
Mortgage with evidence of recording thereon upon receipt thereof from the public
recording office. The Trustee shall request that the Seller correct or cure such
omission, defect or other irregularity, or substitute a Mortgage Loan pursuant
to the provisions of Section 2.03(c), within 90 days

                                       48
<PAGE>

from the date the Seller was notified of such omission or defect and, if the
Seller does not correct or cure such omission or defect within such period, that
the Seller purchase such Mortgage Loan from the Trust Fund within 90 days from
the date the Trustee notified the Seller of such omission, defect or other
irregularity at the Purchase Price of such Mortgage Loan. The Purchase Price for
any Mortgage Loan purchased pursuant to this Section 2.02 shall be paid to the
Servicer and deposited by the Servicer in the Collection Account promptly upon
receipt, and, upon receipt by the Trustee of written notification of such
deposit signed by a Servicing Officer, the Trustee, upon receipt of a Request
for Release, shall promptly release to the Seller the related Mortgage File and
the Trustee shall execute and deliver such instruments of transfer or
assignment, without recourse, representation or warranty, as shall be necessary
to vest in the Seller or its designee, as the case may be, any Mortgage Loan
released pursuant hereto, and the Trustee shall have no further responsibility
with regard to such Mortgage Loan. It is understood and agreed that the
obligation of the Seller to purchase, cure or substitute any Mortgage Loan as to
which a material defect in or omission of a constituent document exists shall
constitute the sole remedy respecting such defect or omission available to the
Trustee on behalf of Certificateholders and the NIM Insurer. The preceding
sentence shall not, however, limit any remedies available to the
Certificateholders, the Depositor, the Trustee or the NIM Insurer pursuant to
the Sale Agreement. The Trustee shall be under no duty or obligation to inspect,
review and examine such documents, instruments, certificates or other papers to
determine that they are genuine, enforceable, recordable or appropriate to the
represented purpose, or that they have actually been recorded, or that they are
other than what they purport to be on their face. The Trustee shall keep
confidential the name of each Mortgagor and the Trustee shall not solicit any
such Mortgagor for the purpose of refinancing the related Mortgage Loan. It is
understood and agreed that all rights and benefits relating to the solicitation
of any Mortgagors and the attendant rights, title and interest in and to the
list of Mortgagors and data relating to their Mortgages shall be retained by the
Servicer.

      Within 70 days of the Closing Date, the Trustee shall deliver to the
Depositor, the Servicer and the NIM Insurer the Trustee's Certification,
substantially in the form of Exhibit D attached hereto, evidencing the
completeness of the Mortgage Files, with any exceptions noted thereto.

      SECTION 2.03. Representations, Warranties and Covenants of the Depositor.

      (a) The Depositor hereby represents and warrants to the Servicer, the
Trustee and the NIM Insurer as follows, as of the date hereof

            (i) The Depositor is duly organized and is validly existing as a
      corporation in good standing under the laws of the State of Delaware and
      has full power and authority (corporate and other) necessary to own or
      hold its properties and to conduct its business as now conducted by it and
      to enter into and perform its obligations under this Agreement and the
      Sale Agreement.

            (ii) The Depositor has the full corporate power and authority to
      execute, deliver and perform, and to enter into and consummate the
      transactions contemplated by, this Agreement and the Sale Agreement and
      has duly authorized, by all necessary corporate action on its part, the
      execution, delivery and performance of this Agreement and the Sale
      Agreement; and this Agreement and the Sale Agreement, assuming the due
      authorization, execution and delivery hereof by the other parties hereto,
      constitutes a legal, valid and binding obligation of the Depositor,
      enforceable against the Depositor in accordance with its terms, subject,
      as to enforceability, to (i) bankruptcy, insolvency, reorganization,
      moratorium and other similar laws affecting creditors' rights generally
      and (ii) general principles of equity, regardless of whether enforcement
      is sought in a proceeding in equity or at law.

<PAGE>

            (iii) The execution and delivery of this Agreement and the Sale
      Agreement by the Depositor, the consummation of the transactions
      contemplated by this Agreement and the Sale Agreement, and the fulfillment
      of or compliance with the terms hereof are in the ordinary course of
      business of the Depositor and will not (A) result in a material breach of
      any term or provision of the charter or by-laws of the Depositor or (B)
      materially conflict with, result in a violation or acceleration of, or
      result in a material default under, the terms of any other material
      agreement or instrument to which the Depositor is a party or by which it
      may be bound or (C) constitute a material violation of any statute, order
      or regulation applicable to the Depositor of any court, regulatory body,
      administrative agency or governmental body having jurisdiction over the
      Depositor; and the Depositor is not in breach or violation of any material
      indenture or other material agreement or instrument, or in violation of
      any statute, order or regulation of any court, regulatory body,
      administrative agency or governmental body having jurisdiction over it
      which breach or violation may materially impair the Depositor's ability to
      perform or meet any of its obligations under this Agreement.

            (iv) No litigation is pending, or, to the best of the Depositor's
      knowledge, threatened, against the Depositor that would materially and
      adversely affect the execution, delivery or enforceability of this
      Agreement and the Sale Agreement or the ability of the Depositor to
      perform its obligations under this Agreement and the Sale Agreement in
      accordance with the terms hereof.

            (v) No consent, approval, authorization or order of any court or
      governmental agency or body is required for the execution, delivery and
      performance by the Depositor of, or compliance by the Depositor with, this
      Agreement and the Sale Agreement or the consummation of the transactions
      contemplated hereby, or if any such consent, approval, authorization or
      order is required, the Depositor has obtained the same. The Depositor
      hereby represents and warrants to the Trustee with respect to each
      Mortgage Loan as of the Closing Date, and following the transfer of the
      Mortgage Loans to it by the Seller, the Depositor had good title to the
      Mortgage Loans and the Mortgage Notes were subject to no offsets, claims,
      liens, mortgage, pledge, charge, security interest, defenses or
      counterclaims.

      (b) To the extent that any fact, condition or event with respect to a
Mortgage Loan constitutes a breach of a representation or warranty of the Seller
under the Sale Agreement, the only right or remedy of the Trustee, the NIM
Insurer or of any Certificateholder shall be the Trustee's right to enforce the
obligations of the Seller under any applicable representation or warranty made
by it. The Trustee acknowledges that the Depositor shall have no obligation or
liability with respect to any breach of any representation or warranty with
respect to the Mortgage Loans (except as set forth in Section 2.03(a)(v)) under
any circumstances.

      (c) Upon discovery by any of the Depositor, the Servicer, the NIM Insurer,
or the Trustee of a breach of any of representations and warranties set forth in
the Sale Agreement that adversely and materially affects the value of the
related Mortgage Loan, prepayment charges or the interests of the
Certificateholders, the party discovering such breach shall give prompt written
notice to the other parties. Within 90 days of the discovery of a breach of any
representation or warranty given to the Trustee by the Depositor, the Seller and
assigned to the Trustee, the Depositor, or the Seller shall either (a) cure such
breach in all material respects, (b) repurchase such Mortgage Loan or any
property acquired in respect thereof from the Trustee at the Purchase Price or
(c) within the two year period following the Closing Date, substitute a
Replacement Mortgage Loan for the affected Mortgage Loan. In the event of
discovery of a breach of any representation and warranty of the Seller or the
Depositor, the Trustee shall enforce its rights under the Sale Agreement or
thereunder for the benefit of Certificateholders and the NIM Insurer. If a

to the unenforceability of a prepayment charge, the Trustee shall notify the NIM
Insurer thereof and not seek to enforce the repurchase remedy provided for
herein unless directed in writing to do so by the NIM Insurer. In the event of a
breach of the representations and warranties with respect to the Mortgage Loans
set forth in a Sale Agreement, the Trustee shall at the request of the NIM
Insurer enforce the right of the Trust Fund and the NIM Insurer to be
indemnified for such breach of representation and warranty. In the event that
such breach relates solely to the unenforceability of a prepayment charge,
amounts received in respect of such indemnity up to the amount of such
prepayment charge shall be distributed pursuant to Section 4.04(b)(i)(B). As
provided in the Sale Agreement, if the Seller substitutes for a Mortgage Loan
for which there is a breach of any representations and warranties which
adversely and materially affects the value of such Mortgage Loan and such
substitute mortgage loan is not a Replacement Mortgage Loan, under the terms of
the Sale Agreement, the Seller will, in exchange for such substitute Mortgage
Loan, (i) provide the applicable Purchase Price for the affected Mortgage Loan
or (ii) within two years of the Closing Date, substitute such affected Mortgage
Loan with a Replacement Mortgage Loan. Any such substitution shall not be
effected prior to the additional delivery to the Trustee of a Request for
Release substantially in the form of Exhibit I and shall not be effected unless
it is within two years of the Startup Day. As provided in the Sale Agreement,
the Seller indemnifies and holds the Trust Fund, the Trustee, the Depositor, the
NIM Insurer, the Servicer and each Certificateholder harmless against any and
all taxes, claims, losses, penalties, fines, forfeitures, reasonable legal fees
and related costs, judgments, and any other costs, fees and expenses that the
Trust Fund, the Trustee, the Depositor, the NIM Insurer, the Servicer and any
Certificateholder may sustain in connection with any actions of the Seller
relating to a repurchase of a Mortgage Loan other than in compliance with the
terms of this Section 2.03 and the Sale Agreement, to the extent that any such
action causes (i) any federal or state tax to be imposed on the Trust Fund or
any REMIC provided for herein, including without limitation, any federal tax
imposed on "prohibited transactions" under Section 860F(a)(1) of the Code or on
"contributions after the startup day" under Section 860G(d)(1) of the Code, or
(ii) any REMIC created hereunder to fail to qualify as a REMIC at any time that
any Certificate is outstanding.

      With respect to any Mortgage Loan repurchased by the Depositor pursuant to
this Agreement or by the Seller pursuant to the Sale Agreement, the principal
portion of the funds received by the Servicer in respect of such repurchase of a
Mortgage Loan will be considered a Principal Prepayment and shall be deposited
by the Servicer in the Certificate Account pursuant to Section 3.05. The
Trustee, upon receipt of the full amount of the Purchase Price for a Deleted
Mortgage Loan, or upon receipt of the Mortgage File for a Replacement Mortgage
Loan substituted for a Deleted Mortgage Loan, shall release or cause to be
released and reassign to the Depositor or the Seller, as applicable, the related
Mortgage File for the Deleted Mortgage Loan and shall execute and deliver such
instruments of transfer or assignment, in each case without recourse,
representation or warranty, as shall be necessary to vest in such party or its
designee or assignee title to any Deleted Mortgage Loan released pursuant
hereto, free and clear of all security interests, liens and other encumbrances
created by this Agreement, which instruments shall be prepared by the Trustee,
and the Trustee shall not have any further responsibility with respect to the
Mortgage File relating to such Deleted Mortgage Loan.

      With respect to each Replacement Mortgage Loan to be delivered to the
Trustee pursuant to the terms of this Article II in exchange for a Deleted
Mortgage Loan: (i) the Depositor or the Seller, as applicable, must deliver to
the Trustee the Mortgage File for the Replacement Mortgage Loan containing the
documents set forth in Section 2.01 along with a written certification
certifying as to the delivery of such Mortgage File and containing the granting
language set forth in the first sentence of Section 2.01; and (ii) the Depositor
will be deemed to have made, with respect to such Replacement Mortgage Loan,
each of the representations and warranties made by it with respect to the
related Deleted Mortgage Loan. The Trustee shall review the Mortgage File with
respect to each Replacement Mortgage Loan and certify to the NIM Insurer and the
Depositor that all documents required by Section 2.01 have been executed and
received.

                                       51
<PAGE>

      For any month in which the Seller substitutes one or more Replacement
Mortgage Loans for one or more Deleted Mortgage Loans, the Seller will determine
the amount (if any) by which the aggregate principal balance of all such
Replacement Mortgage Loans as of the date of substitution and the aggregate
prepayment penalties with respect to such Replacement Mortgage Loans is less
than the aggregate Stated Principal Balance (after application of the principal
portion of the Scheduled Payment due in the month of substitution) and aggregate
prepayment penalties of all such Deleted Mortgage Loans. An amount equal to the
aggregate of the deficiencies described in the preceding sentence (such amount,
the "Substitution Adjustment Amount") shall be delivered by the Seller to the
Servicer for deposit into the Collection Account on the Determination Date for
the Distribution Date relating to the Prepayment Period during which the related
Mortgage Loan became required to be purchased or replaced hereunder.

      The Seller shall give or cause to be given written notice to the
Certificateholders and the NIM Insurer that such substitution has taken place,
shall amend the Mortgage Loan Schedule to reflect the removal of such Deleted
Mortgage Loan from the terms of this Agreement and the substitution of the
Replacement Mortgage Loan or Replacement Mortgage Loans and shall deliver a copy
of such amended Mortgage Loan Schedule to the NIM Insurer and the Trustee. Upon
such substitution by the Seller, such Replacement Mortgage Loan or Replacement
Mortgage Loans shall constitute part of the Mortgage Pool and shall be subject
in all respects to the terms of this Agreement and the Sale Agreement, including
all applicable representations and warranties thereof included in the Sale
Agreement as of the date of substitution.

      In addition, the Seller shall obtain at its own expense and deliver to the
Trustee and the NIM Insurer an Opinion of Counsel addressed to the Trustee and
the NIM Insurer to the effect that such substitution will not (a) cause any
federal tax to be imposed on the Trust Fund or any REMIC provided for herein,
including without limitation, any federal tax imposed on "prohibited
transactions" under Section 860F(a)(1) of the Code or on "contributions after
the startup day" under Section 860G(d)(1) of the Code or (b) adversely affect
the status of any REMIC provided for herein as a REMIC. If any such Opinion of
Counsel can not be delivered, then such substitution may only be effected at
such time as the required Opinion of Counsel can be given.

      (d) It is understood and agreed that the representations, warranties and
indemnification (i) set forth in this Section 2.03 and (ii) of the Seller and
the Depositor set forth in the Sale Agreement and assigned to the Trustee by the
Depositor hereunder shall each survive delivery of the Mortgage Files and the
Assignment of Mortgage of each Mortgage Loan to the Trustee and shall continue
throughout the term of this Agreement.

      SECTION 2.04. Representations and Warranties of the Servicer.

      The Servicer hereby represents and warrants to the Depositor and the
Trustee as follows, as of the date hereof

            (i) The Servicer is a duly formed limited partnership and is validly

      state in which a Mortgaged Property is located or is otherwise not
      required under applicable law to effect such qualification and, in any
      event, is in compliance with the doing business laws of any such state, to
      the extent necessary to ensure its ability to enforce each Mortgage Loan,
      to service the Mortgage Loans in accordance with the terms of this
      Agreement and to perform any of its other obligations under this Agreement
      in accordance with the terms hereof.

                                       52

            (ii) The Servicer has the power and authority to service each
      Mortgage Loan, and to execute, deliver and perform, and to enter into and
      consummate the transactions contemplated by this Agreement and has duly

      the execution, delivery and performance of this Agreement; and this
      Agreement, assuming the due authorization, execution and delivery hereof
      by the other parties hereto, constitutes a legal, valid and binding
      obligation of the Servicer, enforceable against the Servicer in accordance
      with its terms, except that (a) the enforceability hereof may be limited
      by bankruptcy, insolvency, moratorium, receivership and other similar laws
      relating to creditors' rights generally and (b) the remedy of specific
      performance and injunctive and other forms of equitable relief may be
      subject to equitable defenses and to the discretion of the court before
      which any proceeding therefor may be brought.

            (iii) The execution and delivery of this Agreement by the Servicer,

      of any other of the transactions contemplated by this Agreement, and the
      fulfillment of or compliance with the terms hereof are in the ordinary
      course of business of the Servicer and will not (A) result in a material
      breach of any term or provision of the charter or by-laws of the Servicer
      or (B) materially conflict with, result in a material breach, violation or
      acceleration of, or result in a material default under, the terms of any
      other material agreement or instrument to which the Servicer is a party or
      by which it may be bound, or (C) constitute a material violation of any
      statute, order or regulation applicable to the Servicer of any court,
      regulatory body, administrative agency or governmental body having
      jurisdiction over the Servicer; and the Servicer is not in breach or
      violation of any material indenture or other material agreement or
      instrument, or in violation of any statute, order or regulation of any
      court, regulatory body, administrative agency or governmental body having
      jurisdiction over it which breach or violation may materially impair the
      Servicer's ability to perform or meet any of its obligations under this
      Agreement.

            (iv) The Servicer is an approved servicer of mortgage loans for
      Fannie Mae and is an approved seller of seasoned mortgage loans and
      servicer of all types of mortgage loans for Freddie Mac.

            (v) No litigation is pending or, to the best of the Servicer's
      knowledge, threatened, against the Servicer that would materially and
      adversely affect the execution, delivery or enforceability of this
      Agreement or the ability of the Servicer to service the Mortgage Loans or
      to perform any of its other obligations under this Agreement in accordance
      with the terms hereof.

            (vi) No consent, approval, authorization or order of any court or
      governmental agency or body is required for the execution, delivery and
      performance by the Servicer of, or compliance by the Servicer with, this
      Agreement or the consummation of the transactions contemplated hereby, or
      if any such consent, approval, authorization or order is required, the
      Servicer has obtained the same.

            (vii) The Servicer has fully furnished and will fully furnish (for
      the period it serviced the Mortgage Loans), in accordance with the Fair
      Credit Reporting Act and its implementing regulations, accurate and
      complete information (e.g., favorable and unfavorable) on its borrower
      credit files to Equifax, Experian and Trans Union Credit Information
      Company on a monthly basis.

      SECTION 2.05. Substitutions and Repurchases of Mortgage Loans Which Are
Not "Qualified Mortgages".

      Upon discovery by the Depositor, the Servicer or the Trustee that any
Mortgage Loan does not constitute a "qualified mortgage" within the meaning of
section 860G(a)(3) of the Code, the party discovering such fact shall promptly
(and in any event within 5 Business Days of discovery) give written notice
thereof to the other parties. In connection therewith, the Depositor shall, at
the Depositor's option, either (1) substitute, if the conditions in Section
2.03(c) with respect to substitutions are satisfied, a Replacement Mortgage Loan
for the affected Mortgage Loan, or (ii) repurchase the affected Mortgage Loan
within 90 days of such discovery in the same manner as it would a Mortgage Loan
for a breach of representation or warranty contained in Section 2.03. The
Trustee shall reconvey to the Depositor the Mortgage Loan to be released
pursuant hereto in the same manner, and on the same terms and conditions, as it
would a Mortgage Loan repurchased for breach of a representation or warranty
contained in Section 2.03.

      SECTION 2.06. Authentication and Delivery of Certificates.

      The Trustee acknowledges the transfer and assignment to it of the Trust
Fund and, concurrently with such transfer and assignment, the Trustee has caused
to be authenticated and delivered to or upon the order of the Depositor, in
exchange for the Mortgage Loans, Certificates duly authenticated by the Trustee
in authorized denominations evidencing ownership of the entire Trust Fund. The
Trustee agrees to hold the Trust Fund and exercise the rights referred to above
for the benefit of all present and future Holders of the Certificates and to
perform its duties set forth in this Agreement in accordance with the provisions
hereof.

      SECTION 2.07. REMIC Elections.

      (a) The Depositor hereby instructs and authorizes the Trustee to make an
appropriate election to treat each of the Lower Tier REMIC and the Upper Tier
REMIC as a REMIC. The Trustee shall sign the returns providing for such
elections and such other tax or information returns which are required to be
signed by the Trustee under applicable law. This Agreement shall be construed so
as to carry out the intention of the parties that each of the Lower Tier REMIC
and the Upper Tier REMIC be treated as a REMIC at all times prior to the date on
which the Trust Fund is terminated.

      (b) The Preliminary Statement sets forth the designations and "latest
possible maturity date" for federal income tax purposes of all interests created
hereby. The "Startup Day," as defined in Section 860G(a)(9) of the Code, for
purposes of the REMIC Provisions shall be the Closing Date. Each REMIC's fiscal
year shall be the calendar year.

      The Lower Tier REMIC shall consist of all of the assets of the Trust Fund
(other than (i) the right to receive the payments distributable to the Class P
Certificates pursuant to Section 4.04(b)(i) hereof, (ii) the interests issued by
the Lower Tier REMIC, (iii) the grantor trusts described in this Section 2.07
and (iv) each Cap Contract and the Cap Contract Account). The Lower Tier REMIC
shall issue the Lower Tier REMIC Regular Interests which shall be designated as
regular interests of such REMIC and shall issue the Class LTR Interest that
shall be designated as the sole class of residual interest in the Lower Tier
REMIC. Each of the Lower Tier REMIC Regular Interests shall have the
characteristics set forth in its definition.

      The assets of the Upper Tier REMIC shall be the Lower Tier REMIC Regular
Interests. The REMIC Regular Interests shall be designated as the regular
interests in the Upper Tier REMIC and the Residual Interest shall be designated
as the sole class of residual interest in the Upper Tier REMIC. For

                                       54
<PAGE>

federal income tax purposes, the Pass-Through Rate on each REMIC Regular
Interest (other than the Uncertificated Class C Interest) and on the sole class
of residual interest in the Upper Tier REMIC shall be subject to a cap equal to
the Net Rate.

      The beneficial ownership of the Class LTR Interest and the Residual
Interest shall be represented by the Class R Certificate. The Class LTR Interest
shall not have a principal balance or bear interest.

      (c) The "tax matters person" with respect to each REMIC for purposes of
the REMIC Provisions shall be the beneficial owner of the Class R Certificate;
provided, however, that the Holder of a Class R Certificate, by its acceptance
thereof, irrevocably appoints the Trustee as its agent and attorney-in-fact to
act as "tax matters person" with respect to each such REMIC for purposes of the
REMIC Provisions. If there is more than one beneficial owner of the Class R
Certificate, the "tax matters person" shall be the Person with the greatest
percentage interest in the Class R Certificate and, if there is more than one
such Person, shall be determined under Treasury regulation Section 1.860F-4(d)
and Treasury regulation Section 301.6231(a)(7)-1.

      (d) It is intended that the rights of the Class A-1A Certificates, Class
A-1B Certificates, Class A-2A Certificates, Class A-2B Certificates, Class A-2C
Certificates, Class R Certificate, Class M-1 Certificates, Class M-2
Certificates, Class M-3 Certificates, Class B-1 Certificates, Class B-2
Certificates and Class B-3 Certificates to receive payments of Excess Interest
shall be treated as a right in interest rate cap contracts written by the Class
C Certificateholders in favor of the holders of the Class A-1A Certificates,
Class A-1B Certificates, Class A-2A Certificates, Class A-2B Certificates, Class
A-2C Certificates, Class R Certificate, Class M-1 Certificates, Class M-2
Certificates, Class M-3 Certificates, Class B-1 Certificates, Class B-2
Certificates and Class B-3 Certificates, and such shall be accounted for as
property held separate and apart from the regular interests in the Upper Tier
REMIC held by the holders of the Class A-1A Certificates, Class A-1B
Certificates, Class A-2A Certificates, Class A-2B Certificates, Class A-2C
Certificates, Class M-1 Certificates, Class M-2 Certificates, Class M-3
Certificates, Class B-1 Certificates, Class B-2 Certificates and Class B-3
Certificates and the residual interest in the Upper Tier REMIC held by the
holder of the Class R Certificate. This provision is intended to satisfy the
requirements of Treasury Regulations Section 1.860G-2(i) for the treatment of
property rights coupled with REMIC interests to be separately respected and
shall be interpreted consistently with such regulation. On each Distribution
Date, to the extent that any of the Class A-1A Certificates, Class A-1B
Certificates, Class A-2A Certificates, Class A-2B Certificates, Class A-2C
Certificates, Class R Certificate, Class M-1 Certificates, Class M-2
Certificates, Class M-3 Certificates, Class B-1 Certificates, Class B-2
Certificates and Class B-3 Certificates receive payments in respect of Excess
Interest, such amounts will be treated as distributed by the Upper Tier REMIC to
the Class C Certificates pro rata in payment of the amounts specified in Section
4.04(f) and then paid to the relevant Class of Certificates pursuant to the
related interest cap agreement.

      (e) The parties intend that the portion of the Trust Fund consisting of
the Uncertificated Class C Interest, the Cap Contract Account, the Cap Contracts
and the obligation of the holders of the Class C Certificates to pay amounts in
respect of Excess Interest to the holders of the Class A-1A Certificates, Class
A-1B Certificates, Class A-2A Certificates, Class A-2B Certificates, Class A-2C
Certificates, Class R Certificate, Class M-1 Certificates, Class M-2
Certificates, Class M-3 Certificates, Class B-1 Certificates, Class B-2
Certificates and Class B-3 Certificates shall be treated as a "grantor trust"
under the Code, for the benefit of the holders of the Class C Certificates, and
the provisions hereof shall be interpreted consistently with this intention. In
furtherance of such intention, the Trustee shall (i) furnish or cause to be
furnished to the holders of the Class C Certificates information regarding their
allocable share, if any, of the income with respect to such grantor trust, (ii)
file or cause to be filed with the Internal Revenue Service Form 1041 (together
with any necessary attachments) and such other forms as may be applicable and
(iii) comply with such information reporting obligations with respect to

                                       55
<PAGE>

payments from such grantor trust to the holders of Class A-1A Certificates,
Class A-1B Certificates, Class A-2A Certificates, Class A-2B Certificates, Class
A-2C Certificates, Class R Certificate, Class M-1 Certificates, Class M-2
Certificates, Class M-3 Certificates, Class B-1 Certificates, Class B-2
Certificates, Class B-3 Certificates and Class C Certificates as may be
applicable under the Code.

      (f) The parties intend that the portion of the Trust Fund consisting of
the right to receive the payments distributable to the Class P Certificates
pursuant to Section 4.04(b)(i) hereof shall be treated as a "grantor trust"
under the Code, for the benefit of the holders of the Class P Certificates, and
the provisions hereof shall be interpreted consistently with this intention. In
furtherance of such intention, the Trustee shall (i) furnish or cause to be
furnished to the holders of the Class P Certificates information regarding their
allocable share of the income with respect to such grantor trust and (ii) file
or cause to be filed with the Internal Revenue Service Form 1041 (together with
any necessary attachments) and such other forms as may be applicable.

      (g) The parties intend that the portion of the Trust Fund consisting of
the Class R Certificate and the right of the Class C Certificates to receive the
amounts described in Section 9.01(f) hereof shall be treated as a "grantor
trust" under the Code, for the benefit of the holders of the Class R
Certificates and the Class C Certificates, and the provisions hereof shall be
interpreted consistent with this intention. In furtherance of this intention,
the Trustee shall (i) furnish or cause to be furnished to the holders of the
Class R Certificate and the Class C Certificates information regarding their
allocable share of the income with respect to such grantor trust, (ii) file or
cause to be filed with the Internal Revenue Service Form 1041 (together with any
necessary attachments) and such other forms as may be applicable and (iii)
comply with such information reporting obligations with respect to payments from
such grantor trust as may be applicable under the Code.

      All payments of principal and interest at the Net Mortgage Rate on each of
the Mortgage Loans (other than payments distributable to the Class P
Certificates pursuant to Section 4.04(b)(i) hereof) received from the Mortgage
Loans shall be paid to the Lower Tier REMIC Regular Interests until the
principal balance of all such interests have been reduced to zero and any losses
allocated to such interests have been reimbursed. Any excess amounts shall be
distributed to the Class LTR Interest. On each Distribution Date, payments and
losses shall be allocated among the Lower Tier REMIC Regular Interests so that
(i) each of the Lower Tier REMIC I Marker Interests shall have a principal
balance equal to 25% of the principal balance of the Corresponding Certificates,
(ii) the Class LTIX Interest has a principal balance equal to the excess of (x)
50% of the remaining principal balance of the Mortgage Loans over (y) the
aggregate principal balance of the Lower Tier REMIC I Marker Interests (if
necessary to reflect an increase in overcollateralization, accrued and unpaid
interest on the Class LTIX interest may be added to its principal amount to
achieve this result) and (iii) the aggregate principal amount of the Class
LTII1A Interest, Class LTII1B Interest, Class LTII2A Interest, Class LTII2B
Interest and the Class LTIIX Interest shall equal 50% of the remaining principal
balance of the Mortgage loans. Distributions and losses allocated to the Lower
Tier REMIC Regular Interests described in clause (iii) of the preceding sentence
will be allocated among such Lower Tier REMIC Regular Interests in the following
manner: (x) distributions shall be deemed made to such Lower Tier REMIC Regular
Interests first, so as to keep the principal balance of the each such Lower Tier
REMIC Regular Interest with "B" at the end of its designation equal to 0.05% of
the aggregate scheduled principal balance of the Mortgage Loans in the related
Mortgage Group; second, to such Lower Tier REMIC Regular Interests with "A" at
the end of its designation so that the uncertificated principal balance of each
such Lower Tier REMIC Regular Interest is equal to 0.05% of the excess of (I)
the aggregate scheduled principal balance of the Mortgage Loans in the related
Mortgage Group over (II) the aggregate principal balance of Certificate Group
One, in the case of Group One, or Certificate Group Two, in the case of Group
Two (except that if 0.05% of any such excess is greater than the principal
amount of the related Lower Tier REMIC

                                       56
<PAGE>

II Marker Interest with "A" at the end of its designation, the least amount of
principal shall be distributed to each Lower Tier REMIC II Marker Interest with
"A" at the end of its designation such that the Lower Tier REMIC Subordinated
Balance Ratio is maintained) and finally, any remaining distributions of
principal to the Class LTIIX Interest and (y) losses shall be allocated among
the Lower Tier REMIC Regular Interests described in clause (iii) of the
preceding sentence in the following manner: (x) losses shall be deemed allocated
to such Lower Tier REMIC Regular Interests first, so as to keep the principal
balance of the each such Lower Tier REMIC Regular Interest with "B" at the end
of its designation equal to 0.05% of the aggregate scheduled principal balance
of the Mortgage Loans in the related Mortgage Group; second, to such Lower Tier
REMIC Regular Interests with "A" at the end of its designation so that the
uncertificated principal balance of each such Lower Tier REMIC Regular Interest
is equal to 0.05% of the excess of (I) the aggregate scheduled principal balance
of the Mortgage Loans in the related Mortgage Group over (II) the aggregate
principal balance of Certificate Group One, in the case of Group One, or
Certificate Group Two, in the case of Group Two (except that if 0.05% of any
such excess is greater than the principal amount of the related Lower Tier REMIC
II Marker Interest with "A" at the end of its designation, the least amount of
losses shall be allocated to each Lower REMIC II Marker Interest with "A" at the
end of its designation such that the Lower Tier REMIC Subordinated Balance Ratio
is maintained) and finally, any remaining losses to the Class LTIIX Interest.
Notwithstanding the preceding two sentences, however, losses not allocated to
any Class of Certificates will not be allocated to any REMIC 1 Regular
Interests. All computations with respect to the Lower Tier REMIC Regular
Interests shall be taken out to ten decimal places.

      Any available funds remaining in the Lower Tier REMIC on a Distribution
Date after distributions to the Lower Tier REMIC Regular Interests shall be
distributed to the Class R Certificates in respect of the Class LTR Interest.

      If on any Distribution Date the Certificate Principal Balance of any Class
of Certificates is increased pursuant to the last sentence of the definition of
"Certificate Principal Balance", then there shall be an equivalent increase in
the principal amounts of the Lower Tier REMIC Regular Interests, with such
increase allocated (before the making of distributions and the allocation of
losses on the Lower Tier REMIC Regular Interests on such Distribution Date)
among the Lower Tier REMIC Regular Interests so that, to the greatest extent
possible, (i) each of the Lower Tier REMIC I Marker Interests has a principal
balance equal to 25% of the principal balance of the Corresponding Certificates,
(ii) the Class LTIX Interest has a principal balance equal to the excess of (x)
50% of the remaining principal balance of the Mortgage Loans over (y) the
aggregate principal balance of the Lower Tier REMIC I Marker Interests and (iii)
the aggregate principal amount of the Lower Tier REMIC II Marker Interests and
the Class LTIIX Interest shall equal 50% of the remaining principal balance of
the Mortgage Loans. Allocations in connection with clause (iii) shall be made so
that, to the greatest extent possible, (a) the principal balance of each Lower
Tier REMIC II Marker Interest with "B" at the end of its designation equals
0.05% of the aggregate scheduled principal balance of the Mortgage Loans in
related Mortgage Group, (b) the principal balance of each Lower Tier REMIC II
Marker Interest with "A" at the end of its designation equals 0.05% of the
excess of (x) the aggregate scheduled principal balance of the Mortgage Loans in
related Mortgage Group over (y) the aggregate principal balance of Certificate
Group One in the case of the Class LTII1A Interest, or Certificate Group Two in
the case of the Class LTII2A Interest and (c) any remaining allocations are made
to the Class LTIIX Interest.

      For purposes of this Section 2.07, (i) the Class LTII1A Interest and Class
LTII1B Interest shall be related to Group One, and (ii) the Class LTII2A
Interest and Class LTII2B Interest shall be related to Group Two.

      In the event that any REMIC provided for herein fails to qualify as a
REMIC, loses its status as a REMIC, or incurs federal, state or local taxes as a
result of a prohibited transaction or prohibited contribution under the REMIC
Provisions due to the negligent performance by the Servicer of its duties

                                       57
<PAGE>

and obligations set forth herein, the Servicer shall indemnify the NIM Insurer,
the Trustee and the Trust Fund against any and all Losses resulting from such
negligence; provided, however, that the Servicer shall not be liable for any
such Losses attributable to the action or inaction of the Trustee, the Depositor
or the Holder of the Class R Certificate, as applicable, nor for any such Losses
resulting from misinformation provided by the Holder of the Class R Certificate
on which the Servicer has relied. The foregoing shall not be deemed to limit or
restrict the rights and remedies of the Holder of the Class R Certificate now or
hereafter existing at law or in equity. Notwithstanding the foregoing, however,
in no event shall the Servicer have any liability (1) for any action or omission
that is taken in accordance with and in compliance with the express terms of, or
which is expressly permitted by the terms of, this Agreement, (2) for any Losses
other than arising out of a negligent performance by the Servicer of its duties
and obligations set forth herein, and (3) for any special or consequential
damages to Certificateholders (in addition to payment of principal and interest
on the Certificates).

      In the event that any REMIC provided for herein fails to qualify as a
REMIC, loses its status as a REMIC, or incurs federal, state or local taxes as a
result of a prohibited transaction or prohibited contribution under the REMIC
Provisions due to the negligent performance by the Trustee of its duties and
obligations set forth herein, the Trustee shall indemnify the NIM Insurer and
the Trust Fund against any and all Losses resulting from such negligence;
provided, however, that the Trustee shall not be liable for any such Losses
attributable to the action or inaction of the Servicer, the Depositor or the
Holder of the Class R Certificate, as applicable, nor for any such Losses
resulting from misinformation provided by the Holder of the Class R Certificate
on which the Trustee has relied. The foregoing shall not be deemed to limit or
restrict the rights and remedies of the Holder of the Class R Certificate now or
hereafter existing at law or in equity. Notwithstanding the foregoing, however,
in no event shall the Trustee have any liability (1) for any action or omission
that is taken in accordance with and in compliance with the express terms of, or
which is expressly permitted by the terms of, this Agreement, (2) for any Losses
other than arising out of a negligent performance by the Trustee of its duties
and obligations set forth herein, and (3) for any special or consequential
damages to Certificateholders (in addition to payment of principal and interest
on the Certificates).

      SECTION 2.08. Covenants of the Servicer.

      The Servicer hereby covenants to each of the other parties to this
Agreement as follows:

      (a) the Servicer shall comply in the performance of its obligations under
this Agreement with all reasonable rules and requirements of the insurer under
each Required Insurance Policy;

      (b) no written information, certificate of an officer, statement furnished
in writing or written report delivered to the Depositor, the Trustee or the NIM
Insurer, any affiliate of the Depositor, the Trustee or the NIM Insurer and
prepared by the Servicer pursuant to this Agreement will be inaccurate in any
material respect, provided, however, that the Servicer shall not be responsible
for inaccurate information provided to it by third parties.

      SECTION 2.09. [RESERVED].

      SECTION 2.10. [RESERVED].

      SECTION 2.11. Permitted Activities of the Trust Fund. The Trust Fund is
created for the object and purpose of engaging in the Permitted Activities. In
furtherance of the foregoing, the Trustee is hereby authorized and directed to
execute and deliver, on behalf of the Trust Fund, the Cap Contracts, and to
execute and deliver on behalf of the Trust Fund, and to perform the duties and
obligations of the Trustee under an insurance and indemnity agreement with a NIM
Insurer and any other agreement or

                                       58
<PAGE>

instrument related thereto, in each case in such form as the Depositor shall
direct or shall approve, the execution and delivery of any such agreement by the
Depositor to be conclusive evidence of its approval thereof.

      SECTION 2.12. Qualification Special Purpose Entity. For purposes of SFAS
140, the parties hereto intend that the Trust Fund shall be treated as a
"qualifying special purpose entity" as such term is used in SFAS 140 and any
successor rule thereto and its power and authority as stated in Section 2.11 of
this Agreement shall be limited in accordance with paragraph 35 of SFAS 140.

                                  ARTICLE III
                 ADMINISTRATION AND SERVICING OF MORTGAGE LOANS

      SECTION 3.01. Servicer to Service Mortgage Loans.

      For and on behalf of the Certificateholders, the Servicer shall service
and administer the Mortgage Loans in accordance with Accepted Servicing
Practices. In connection with such servicing and administration, the Servicer
shall have full power and authority, acting alone and/or through subservicers as
provided in Section 3.02 hereof, to do or cause to be done any and all things
that it may deem necessary or desirable in connection with such servicing and
administration, including but not limited to, the power and authority, subject
to the terms hereof (i) to execute and deliver, on behalf of the
Certificateholders and the Trustee, customary consents or waivers and other
instruments and documents, (ii) to consent to transfers of any Mortgaged
Property and assumptions of the Mortgage Notes and related Mortgages (but only
in the manner provided in this Agreement), (iii) to collect any Insurance
Proceeds and other Liquidation Proceeds and (iv) subject to Section 3.12(a), to
effectuate foreclosure or other conversion of the ownership of the Mortgaged
Property securing any Mortgage Loan; provided that, subject to Section 6.03, the
Servicer shall not take any action that is inconsistent with or prejudices the
interests of the Trust Fund or the Certificateholders in any Mortgage Loan
serviced by it under this Agreement or the rights and interests of the other
parties to this Agreement except as otherwise required by this Agreement or by
law. The Servicer shall represent and protect the interest of the Trust Fund in
the same manner as it currently protects its own interest in mortgage loans in
its own portfolio in any claim, proceeding or litigation regarding a Mortgage
Loan, but in any case not in any manner that is a lesser standard than that
provided in the first sentence of this Section 3.01. The Servicer shall not make
or permit any modification, waiver or amendment of any term of any Mortgage Loan
which would cause any of the REMICs provided for herein to fail to qualify as a
REMIC or result in the imposition of any tax under Section 860G(a) or 860G(d) of
the Code. Without limiting the generality of the foregoing, the Servicer, in its
own name or in the name of the Depositor and the Trustee, is hereby authorized
and empowered by the Depositor and the Trustee, when the Servicer believes it
appropriate in its reasonable judgment, to execute and deliver, on behalf of the
Trustee, the Depositor, the Certificateholders or any of them, any and all
instruments of satisfaction or cancellation, or of partial or full release or
discharge and all other comparable instruments, with respect to the Mortgage
Loans, and with respect to the Mortgaged Properties held for the benefit of the
Certificateholders. The Servicer shall prepare and deliver to the Depositor
and/or the Trustee such documents requiring execution and delivery by any or all
of them as are necessary or appropriate to enable the Servicer to service and
administer the Mortgage Loans. If reasonably required by the Servicer, the
Trustee shall furnish the Servicer with a power of attorney in the form attached
hereto as Exhibit J and execute such other documents delivered to it by the
Servicer that are necessary or appropriate to enable the Servicer to carry out
its servicing and administrative duties under this Agreement. Upon receipt of
such documents, the Depositor and/or the Trustee shall execute such documents
and deliver them to the Servicer. The Trustee shall have no liability with
respect to any misuse of such power of attorney and shall be indemnified by the
Servicer for any costs, liabilities or expenses incurred by the Trustee in
connection therewith.

                                       59
<PAGE>

      In accordance with the standards of the preceding paragraph, the Servicer
shall advance or cause to be advanced funds as necessary for the purpose of
effecting the payment of taxes and assessments on the Mortgaged Properties,
which advances shall be reimbursable in the first instance from related
collections from the Mortgagors pursuant to Section 3.06, and further as
provided in Section 3.08. To the extent that a Mortgage does not provide for
escrow payments, (i) the Servicer shall determine whether any such payments are
made by the Mortgagor in a manner and at a time that is necessary to avoid the
loss of the Mortgaged Property due to a tax sale or the foreclosure as a result
of a tax lien and (ii) the Servicer shall ensure that all insurance required to
be maintained on the Mortgaged Property pursuant to this Agreement is
maintained. If any such payment has not been made and the Servicer receives
notice of a tax lien with respect to the Mortgage Loan being imposed, the
Servicer will, to the extent required to avoid loss of the Mortgaged Property,
advance or cause to be advanced funds necessary to discharge such lien on the
Mortgaged Property. All costs incurred by the Servicer, if any, in effecting the
timely payments of taxes and assessments on the Mortgaged Properties and related
insurance premiums shall not, for the purpose of calculating monthly
distributions to the Certificateholders, be added to the Stated Principal
Balance under the related Mortgage Loans, notwithstanding that the terms of such
Mortgage Loans so permit.

      The Servicer shall deliver a list of Servicing Officers and specimen
signatures to the Trustee by the Closing Date.

      The Servicer will transmit full-file credit reporting data for each
Mortgage Loan pursuant to Fannie Mae Guide Announcement 97-02 and that for each
Mortgage Loan, the Servicer agrees that it shall report one of the following
statuses each month as follows: current, delinquent (30-, 60-, 90-days, etc.),
foreclosed or charged-off.

      The Servicer shall have at least 30 days' notice of the appointment of a
NIM Insurer prior to being required to deliver any notices pursuant to this
Agreement to such NIM Insurer.

      SECTION 3.02. Servicing and Subservicing; Enforcement of the Obligations
of Servicer.

      (a) The Servicer may arrange for the subservicing of any Mortgage Loan by
a subservicer, which may be an affiliate (each, a "subservicer") pursuant to a
subservicing agreement (each, a "Subservicing Agreement"); provided, however,
that (i) such subservicing arrangement and the terms of the related subservicing
agreement must provide for the servicing of such Mortgage Loans in a manner
consistent with the servicing arrangements contemplated hereunder, (ii) that
such agreement would not result in a withdrawal or downgrading by any Rating
Agency of the ratings of any Certificates or any of the NIM Notes evidenced by a
letter to that effect delivered by each Rating Agency to the Depositor and the
NIM Insurer and (iii) the NIM Insurer shall have consented to such subservicing
agreement which consent shall not unreasonably be withheld. Notwithstanding the
provisions of any subservicing agreement, any of the provisions of this
Agreement relating to agreements or arrangements between the Servicer and a
subservicer or reference to actions taken through a subservicer or otherwise,
the Servicer shall remain obligated and liable to the Depositor, the Trustee and
the Certificateholders for the servicing and administration of the Mortgage
Loans in accordance with the provisions of this Agreement without diminution of
such obligation or liability by virtue of such subservicing agreements or
arrangements or by virtue of indemnification from the subservicer and to the
same extent and under the same terms and conditions as if the Servicer alone
were servicing and administering the Mortgage Loans. Every subservicing
agreement entered into by the Servicer shall contain a provision giving any
successor servicer the option to terminate such agreement with the consent of
the NIM Insurer in the event a successor servicer is appointed. All actions of
the each subservicer performed pursuant to the related subservicing agreement
shall be performed as an agent of the Servicer with the same force and effect as
if

                                       60
<PAGE>

performed directly by the Servicer. The Servicer shall deliver to the NIM
Insurer and the Trustee copies of all subservicing agreements.

      (b) For purposes of this Agreement, the Servicer shall be deemed to have
received any collections, recoveries or payments with respect to the Mortgage
Loans that are received by a subservicer regardless of whether such payments are
remitted by the subservicer to the Servicer.

      SECTION 3.03. Rights of the Depositor and the Trustee in Respect of the
Servicer.

      Neither the Trustee nor the Depositor shall have any responsibility or
liability for any action or failure to act by the Servicer, and neither of them
is obligated to supervise the performance of the Servicer hereunder or
otherwise.

      SECTION 3.04. Trustee to Act as Servicer.

      In the event that the Servicer shall for any reason no longer be the
Servicer hereunder (including by reason of an Event of Default), the Trustee or
its designee shall, within a period of time not to exceed ninety (90) days from
the date of notice of termination or resignation, thereupon assume all of the
rights and obligations of the Servicer hereunder arising thereafter except that
the Trustee shall not be (i) liable for losses of the Servicer pursuant to
Section 3.10 hereof or any acts or omissions of such predecessor Servicer
hereunder, (ii) obligated to make Advances or Servicing Advances if it is
prohibited from doing so by applicable law, (iii) obligated to effectuate
repurchases or substitutions of Mortgage Loans hereunder, including pursuant to
Section 2.02 or 2.03 hereof, (iv) responsible for any expenses of the Servicer
pursuant to Section 2.03 or (v) deemed to have made any representations and
warranties hereunder, including pursuant to Section 2.04 or the first paragraph
of Section 6.02 hereof; provided, however that the Trustee (subject to clause
(ii) above) or its designee, in its capacity as the successor servicer, shall
immediately assume the terminated or resigning Servicer's obligation to make
Advances and Servicing Advances. No such termination shall affect any obligation
of the Servicer to pay amounts owed under this Agreement and to perform its
duties under this Agreement until its successor assumes all of its rights and
obligations hereunder. If the Servicer shall for any reason no longer be the
Servicer (including by reason of any Event of Default), the Trustee (or any
other successor servicer) may, at its option, succeed to any rights and
obligations of the Servicer under any subservicing agreement in accordance with
the terms thereof; provided, however, that the Trustee (or any other successor
servicer) shall not incur any liability or have any obligations in its capacity
as servicer under a subservicing agreement arising prior to the date of such
succession unless it expressly elects to assume such obligations of the Servicer
thereunder; and the Servicer shall not thereby be relieved of any liability or
obligations under the subservicing agreement arising prior to the date of such
succession. To the extent any costs or expenses, including without limitation
Servicing Transfer Costs incurred by the Trustee in connection with this Section
3.04 are not paid by the Servicer pursuant to this Agreement within 30 days of
the date of the Trustee's invoice therefor, such amounts shall be payable out of
the Certificate Account; provided that the terminated Servicer shall reimburse
the Trust Fund for any such expense incurred by the Trust Fund upon receipt of a
reasonably detailed invoice evidencing such expenses. If the Trustee is
unwilling or unable to act as servicer, or if the NIM Insurer so directs the
Trustee, the Trustee shall seek to appoint a successor servicer that is eligible
in accordance with the criteria specified this Agreement and reasonably
acceptable to the NIM Insurer.

      The Servicer shall, upon request of the Trustee, but at the expense of the
Servicer, deliver to the assuming party all documents and records relating to
each subservicing agreement and the Mortgage Loans then being serviced and
otherwise use its best efforts to effect the orderly and efficient transfer of
the subservicing agreement to the assuming party.

                                       61
<PAGE>

      In the event that the Servicer shall for any reason no longer be the
Servicer hereunder (including by reason of any Event of Default),
notwithstanding anything to the contrary above, the Trustee and the Depositor
hereby agree that within 10 Business Days or delivery to the Trustee by the
Servicing Rights Pledgee of a letter signed by the Servicer whereby the Servicer
shall resign as Servicer under this Agreement, the Servicing Rights Pledgee or
its designee shall be appointed as successor servicer (provided that at the time
of such appointment the Servicing Rights Pledgee or such designee meets the
requirements of a successor servicer set forth above) and the Servicing Rights
Pledgee agrees to be subject to the terms of this Agreement.

      SECTION 3.05. Collection of Mortgage Loan Payments; Collection Account;
Certificate Account.

      (a) The Servicer shall make reasonable efforts in accordance with Accepted
Servicing Practices to collect all payments called for under the terms and
provisions of the Mortgage Loans to the extent such procedures shall be
consistent with this Agreement and the terms and provisions of any related
Required Insurance Policy. Consistent with the foregoing and subject to Section
3.01 hereof, the Servicer may in its discretion (i) waive any late payment
charge or, if applicable, any penalty interest, or (ii) extend the due dates for
payments due on a Mortgage Note for a period not greater than 180 days;
provided, however, that any extension pursuant to clause (ii) above shall not
affect the amortization schedule of any Mortgage Loan for purposes of any
computation hereunder, except as provided below; provided, further, that the NIM
Insurer's prior written consent shall be required for any modification, waiver
or amendment since the Cutoff Date if the aggregate number of outstanding
Mortgage Loans which have been modified, waived or amended exceeds 5% of the
number of Mortgage Loans as of the Cut-Off Date. In the event of any such
arrangement pursuant to clause (ii) above, subject to Section 4.01, the Servicer
shall make any Advances on the related Mortgage Loan during the scheduled period
in accordance with the amortization schedule of such Mortgage Loan without
modification thereof by reason of such arrangements. Notwithstanding the
foregoing, in the event that any Mortgage Loan is in default or, in the judgment
of the Servicer, such default is reasonably foreseeable, the Servicer,
consistent with the standards set forth in Section 3.01, may also waive, modify
or vary any term of such Mortgage Loan (including modifications that would
change the Mortgage Rate, forgive the payment of principal or interest or extend
the final maturity date of such Mortgage Loan), accept payment from the related
Mortgagor of an amount less than the Stated Principal Balance in final
satisfaction of such Mortgage Loan, or consent to the postponement of strict
compliance with any such term or otherwise grant indulgence to any Mortgagor
(any and all such waivers, modifications, variances, forgiveness of principal or
interest, postponements, or indulgences collectively referred to herein as
"forbearance"), provided, however, that in no event shall the Servicer grant any
such forbearance (other than as permitted by the second sentence of this
Section) with respect to any one Mortgage Loan more than once in any 12 month
period or more than three times over the life of such Mortgage Loan, and
provided, further, that in determining which course of action permitted by this
sentence it shall pursue, the Servicer shall adhere to the standards of Section
3.01. The Servicer's analysis supporting any forbearance and the conclusion that
any forbearance meets the standards of Section 3.01 shall be reflected in
writing in the Mortgage File.

      (b) The Servicer will not waive any prepayment penalty or portion thereof
unless, (i) the enforceability thereof shall have been limited by bankruptcy,
insolvency, moratorium, receivership and other similar laws relating to
creditors' rights generally or is otherwise prohibited by law, or (ii) the
collectability thereof shall have been limited due to acceleration in connection
with a foreclosure or other involuntary payment, or (iii) the prepayment of the
Mortgage Loan is made in connection with the voluntary sale of the related
Mortgaged Property, or (iv) in the Servicer's reasonable judgment as described
in Section 3.01 hereof, (x) such waiver relates to a default or a reasonably
foreseeable default, (y) such waiver would maximize recovery of total proceeds
taking into account the value of such prepayment penalty and related Mortgage
Loan and (z) doing so is standard and customary in servicing

                                       62
<PAGE>

similar Mortgage Loans (including any waiver of a prepayment penalty in
connection with a refinancing of a Mortgage Loan that is related to a default or
a reasonably foreseeable default), or (iv) if sufficient information is not made
available to enable it to collect the prepayment penalty. Except as provided in
the preceding sentence, in no event will the Servicer waive a prepayment penalty
in connection with a refinancing of a Mortgage Loan that is not related to a
default or a reasonably foreseeable default. If the Servicer waives or does not
collect all or a portion of a prepayment penalty relating to a Principal
Prepayment in full or in part due to any action or omission of the Servicer,
other than as provided above, the Servicer shall deposit the amount of such
prepayment penalty (or such portion thereof as had been waived for deposit) into
the Collection Account for distribution in accordance with the terms of this
Agreement.

      (c) The Servicer shall not be required to institute or join in litigation
with respect to collection of any payment (whether under a Mortgage, Mortgage
Note or otherwise or against any public or governmental authority with respect
to a taking or condemnation) if it reasonably believes that enforcing the
provision of the Mortgage or other instrument pursuant to which such payment is
required is prohibited by applicable law.

      (d) The Servicer shall establish and initially maintain, on behalf of the
Trustee for the benefit of the Certificateholders, the Collection Account. The
Servicer shall deposit into the Collection Account daily, within two Business
Days of receipt thereof, in immediately available funds, the following payments
and collections received or made by it on and after the Cut-Off Date with
respect to the Mortgage Loans:

            (i) all payments on account of principal, including Principal
      Prepayments, on the Mortgage Loans, other than principal due on the
      Mortgage Loans on or prior to the Cut-off Date;

            (ii) all payments on account of interest on the Mortgage Loans net
      of the related Servicing Fee permitted under Section 3.15, other than
      interest due on the Mortgage Loans on or prior to the Cut-off Date;

            (iii) all Liquidation Proceeds, other than proceeds to be applied to
      the restoration or repair of the Mortgaged Property or released to the
      Mortgagor in accordance with the Servicer's normal servicing procedures;

            (iv) all Compensating Interest;

            (v) any amount required to be deposited by the Servicer pursuant to
      Section 3.05(g) in connection with any losses on Permitted Investments;

            (vi) any amounts required to be deposited by the Servicer pursuant
      to Section 3.10 hereof;

            (vii) the Purchase Price and any Substitution Adjustment Amount;

            (viii) all Advances made by the Servicer pursuant to Section 4.01;

            (ix) all prepayment penalties; and

            (x) any other amounts required to be deposited hereunder.

                                       63
<PAGE>

      The foregoing requirements for remittance by the Servicer into the
Collection Account shall be exclusive, it being understood and agreed that,
without limiting the generality of the foregoing, late payment charges,
insufficient funds charges and payments in the nature of assumption fees (i.e.
fees related to the assumption of a Mortgage Loan upon the purchase of the
related Mortgaged Property) and other similar ancillary fees (other than
prepayment penalties) if collected, need not be remitted by the Servicer. In the
event that the Servicer shall remit any amount not required to be remitted and
not otherwise subject to withdrawal pursuant to Section 3.08 hereof, it may at
any time withdraw or direct the Trustee, or such other institution maintaining
the Collection Account, to withdraw such amount from the Collection Account, any
provision herein to the contrary notwithstanding. The Servicer shall maintain
adequate records with respect to all withdrawals made pursuant to this Section.
All funds deposited in the Collection Account shall be held in trust for the
Certificateholders until withdrawn in accordance with Section 3.08. In no event
shall the Trustee incur liability for withdrawals from the Collection Account at
the direction of the Servicer.

      (e) [RESERVED].

      (f) The Trustee shall establish and maintain, on behalf of the
Certificateholders, the Certificate Account. The Trustee shall, promptly upon
receipt, deposit or cause to be deposited in the Certificate Account and retain
therein the following:

            (i) the aggregate amount withdrawn by the Servicer from the
      Collection Account and required to be deposited in the Certificate
      Account;

            (ii) any amount required to be deposited by the Trustee pursuant to
      Section 3.05(g) in connection with any losses on Permitted Investments;
      and

            (iii) the Auction Termination Amount or Clean Up Call Price payable
      pursuant to Section 9.01.

      Any amounts received by the Trustee prior to 1:00 p.m. New York City time
(or such earlier deadline for investment in the Permitted Investments designated
by the Trustee) which are required to be deposited in the Certificate Account by
the Servicer shall be invested in Permitted Investments on the Business Day on
which they were received. The foregoing requirements for remittance by the
Servicer and deposit by the Servicer into the Certificate Account shall be
exclusive. In the event that the Servicer shall remit any amount not required to
be remitted and not otherwise subject to withdrawal pursuant to Section 3.08
hereof, it may at any time withdraw such amount from the Certificate Account,
any provision herein to the contrary notwithstanding. All funds deposited in the
Certificate Account shall be held by the Trustee in trust for the
Certificateholders until disbursed in accordance with this Agreement or
withdrawn in accordance with Section 3.08. In no event shall the Trustee incur
liability for withdrawals from the Certificate Account at the direction of the
Servicer.

      (g) Each institution that maintains the Collection Account or the
Certificate Account shall invest the funds in each such account, as directed by
the Servicer or the Trustee, as applicable, in writing, in Permitted
Investments, which shall mature not later than (i) in the case of the Collection
Account the Business Day preceding the related Servicer Remittance Date (except
that if such Permitted Investment is an obligation of the institution that
maintains such Collection Account or is otherwise immediately available, then
such Permitted Investment shall mature not later than the Servicer Remittance
Date) and (ii) in the case of the Certificate Account, the Business Day
immediately preceding the first Distribution Date that follows the date of such
investment (except that if such Permitted Investment is an obligation of the
institution that maintains such Certificate Account or a fund for which such
institution serves as custodian or is otherwise immediately available, then such
Permitted Investment shall mature not later

                                       64
<PAGE>

than such Distribution Date) and, in each case, shall not be sold or disposed of
prior to its maturity. All such Permitted Investments shall be made in the name
of the Servicer or the Trustee, as applicable, for the benefit of the
Certificateholders. All income and gain net of any losses realized from amounts
on deposit in the Collection Account shall be for the benefit of the Servicer as
servicing compensation and shall be remitted to it monthly as provided herein.
The amount of any losses incurred in the Collection Account in respect of any
such investments shall be deposited by the Servicer in the Collection Account
out of the Servicer's own funds immediately as realized. All income and gain net
of any losses realized from amounts on deposit in the Certificate Account shall
be for the benefit of the Trustee and shall be remitted to or withdrawn by it
monthly as provided herein. The amount of any losses incurred in the Certificate
Account in respect of any such investments shall be deposited by the Trustee, in
the Certificate Account out of the Trustee's own funds immediately as realized.

      SECTION 3.06. Collection of Taxes, Assessments and Similar Items; Escrow
Accounts.

      To the extent required by the related Mortgage Note, the Servicer shall
establish and maintain one or more accounts (each, an "Escrow Account") and
deposit and retain therein all collections from the Mortgagors (or advances by
the Servicer) for the payment of taxes, assessments, hazard insurance premiums
or comparable items for the account of the Mortgagors. Nothing herein shall
require the Servicer to compel a Mortgagor to establish an Escrow Account in
violation of applicable law.

      Withdrawals of amounts so collected from the Escrow Accounts may be made
only to effect timely payment of taxes, assessments, hazard insurance premiums,
condominium or PUD association dues, or comparable items, to reimburse the
Servicer out of related collections for any payments made pursuant to Sections
3.01 hereof (with respect to taxes and assessments and insurance premiums) and
3.10 hereof (with respect to hazard insurance), to refund to any Mortgagors any
sums as may be determined to be overages, to pay interest, if required by law or
the terms of the related Mortgage or Mortgage Note, to Mortgagors on balances in
the Escrow Account or to clear and terminate the Escrow Account at the
termination of this Agreement in accordance with Section 9.01 hereof. The Escrow
Accounts shall not be a part of the Trust Fund.

      SECTION 3.07. Access to Certain Documentation and Information Regarding
the Mortgage Loans.

      Upon reasonable advance notice in writing if required by federal
regulation, the Servicer will provide to each Certificateholder that is a
savings and loan association, bank or insurance company certain reports and
reasonable access to information and documentation regarding the Mortgage Loans
sufficient to permit such Certificateholder to comply with applicable
regulations of the OTS or other regulatory authorities with respect to
investment in the Certificates; provided, that the Servicer shall be entitled to
be reimbursed by each such Certificateholder for actual expenses incurred by the
Servicer in providing such reports and access.

      SECTION 3.08. Permitted Withdrawals from the Collection Account and
Certificate Account.

      (a) The Servicer may from time to time, make withdrawals from the
Collection Account for the following purposes:

            (i) to pay to the Servicer (to the extent not previously paid to or
      withheld by the Servicer), as servicing compensation in accordance with
      Section 3.15, that portion of any payment of interest that equals the
      Servicing Fee for the period with respect to which such interest payment
      was made, and, as additional servicing compensation, those other amounts
      set forth in Section 3.15;

                                       65
<PAGE>

            (ii) to reimburse the Servicer for Advances and Servicing Advances
      (to the extent such Servicing Advances would constitute "unanticipated
      expenses" within the meaning of Treasury Regulation Section
      1.860G-1(b)(3)(ii) if paid by one of the REMICs provided for herein)
      occurring after the Cut-off Date made by it with respect to the Mortgage
      Loans, such right of reimbursement pursuant to this subclause (ii) being
      limited to amounts received on particular Mortgage Loan(s) (including, for
      this purpose, Condemnation Proceeds, Insurance Proceeds or Liquidation
      Proceeds) that represent late recoveries of payments of principal and/or
      interest on such particular Mortgage Loan(s) in respect of which any such
      Advance was made;

            (iii) to reimburse the Servicer for any Non-Recoverable Advance
      previously made and, to the extent that such Non-Recoverable Servicing
      Advances would constitute "unanticipated expenses" within the meaning of
      Treasury Regulation Section 1.860G-1(b)(3)(ii) if paid by one of the
      REMICs provided for herein, any Non-Recoverable Servicing Advance;

            (iv) to pay to the Servicer earnings on or investment income with
      respect to funds in or credited to the Collection Account;

            (v) to reimburse the Servicer from Insurance Proceeds for Insured
      Expenses covered by the related Insurance Policy;

            (vi) pay the Servicer any unpaid Servicing Fees and to reimburse it
      for any unreimbursed Servicing Advances, the Servicer's right to
      reimbursement of Servicing Advances pursuant to this subclause (vi) with
      respect to any Mortgage Loan being limited to amounts received on
      particular Mortgage Loan(s) (including, for this purpose, Liquidation
      Proceeds and purchase and repurchase proceeds and including any Subsequent
      Recoveries related to any liquidated Mortgage Loan) that represent late
      recoveries of the payments for which such advances were made pursuant to
      Section 3.01 or Section 3.06;

            (vii) to pay to the Depositor or the Servicer, as applicable, with
      respect to each Mortgage Loan or property acquired in respect thereof that
      has been purchased pursuant to Section 2.02, 2.03 or 3.12, all amounts
      received thereon and not taken into account in determining the related
      Stated Principal Balance of such repurchased Mortgage Loan;

            (viii) to reimburse the Servicer or the Depositor for expenses
      incurred by any of them in connection with the Mortgage Loans or
      Certificates and reimbursable pursuant to Section 3.25 or Section 6.03
      hereof;

            (ix) to reimburse the Trustee for enforcement expenses reasonably
      incurred in respect of a breach of defect giving rise to the purchase
      obligation in Section 2.03 that were incurred in the Purchase Price of the
      Mortgage Loans including any expenses arising out of the enforcement of
      the purchase obligation; provided that any such expenses will be
      reimbursable under this subclause (ix) only to the that such expenses
      would constitute "unanticipated expenses" within the meaning of Treasury
      Regulation Section 1.860G-1(b)(3)(ii) if paid by one of the REMICs
      provided for herein;

            (x) to withdraw pursuant to Section 3.05 any amount deposited in the
      Collection Account and not required to be deposited therein;

            (xi) to clear and terminate the Collection Account upon termination
      of this Agreement pursuant to Section 9.01 hereof; and

                                       66
<PAGE>

            (xii) to reimburse itself for Advances or Servicing Advances from
      amounts in the Collection Account held for future distributions that were
      not included in Available Funds for the preceding Distribution Date. An
      amount equal to the amount withdrawn from the Collection Account pursuant
      to this subclause (xii) shall be deposited in the Collection Account by
      the Servicer on the next succeeding Distribution Date that funds are to be
      distributed to Certificateholders.

      In addition, no later than 1:00 p.m. Eastern Time on the Servicer
Remittance Date, the Servicer shall cause to be withdrawn from the Collection
Account the Interest Funds and the Principal Funds, to the extent on deposit,
and such amount shall be deposited in the Certificate Account.

      The Servicer shall keep and maintain separate accounting, on a Mortgage
Loan by Mortgage Loan basis, for the purpose of justifying any withdrawal from
the Collection Account.

      The Servicer shall provide written notification to the Trustee and the NIM
Insurer on or prior to the next succeeding Servicer Remittance Date upon making
any withdrawals from the Collection Account pursuant to subclauses (iii) and
(viii) above.

      In the event of any failure by the Servicer to remit to the Trustee for
deposit into the Certificate Account any amounts (including any P&I Advance)
required to be so remitted by the Servicer on the Servicer Remittance Date, the
Servicer shall pay to the Trustee, for its own account, interest on such amounts
at the "prime rate" (as specified in the New York edition of the Wall Street
Journal) until such failure is remedied.

      (b) The Trustee shall withdraw funds from the Certificate Account for
distribution to the Certificateholders in the manner specified in this Agreement
(and to withhold from the amounts so withdrawn, the amount of any taxes that it
is authorized to retain pursuant to this Agreement). In addition, the Trustee
may from time to time make withdrawals from the Certificate Account for the
following purposes:

            (i) to withdraw any amount deposited in the Certificate Account and
      not required to be deposited therein;

            (ii) to pay the Trustee any indemnification amounts owed it and to
      clear and terminate the Certificate Account upon termination of the
      Agreement pursuant to Section 9.01 hereof (including paying all amounts
      necessary to the Trustee or the Servicer in connection with any such
      termination);

            (iii) to reimburse the Trustee for expenses incurred by the Trustee
      and reimbursable pursuant to Section 8.06 hereof; and

            (iv) to pay to the Trustee earnings on or investment income with
      respect to funds in or credited to the Certificate Account.

      SECTION 3.09. [RESERVED].

      SECTION 3.10. Maintenance of Hazard Insurance.

      The Servicer shall cause to be maintained, for each Mortgage Loan, hazard
insurance with extended coverage in an amount that is at least equal to the
lesser of (i) the replacement value of the improvements that are part of such
Mortgaged Property, or (ii) the greater of (a) the outstanding principal

                                       67
<PAGE>

balance of the Mortgage Loan and (b) an amount such that the proceeds of such
policy shall be sufficient to prevent the related Mortgagor and/or mortgagee
from becoming a co-insurer or (iii) the amount required under applicable HUD/FHA
regulations. Each such policy of standard hazard insurance shall contain, or
have an accompanying endorsement that contains, a standard mortgagee clause. The
Servicer shall also cause flood insurance to be maintained on property acquired
upon foreclosure or deed in lieu of foreclosure of any Mortgage Loan, to the
extent required under the standards described below. Pursuant to Section 3.05
hereof, any amounts collected by the Servicer under any such policies (other
than the amounts to be applied to the restoration or repair of the related
Mortgaged Property or property thus acquired or amounts released to the
Mortgagor in accordance with the Servicer's normal servicing procedures) shall
be deposited in the Collection Account. Any cost incurred by the Servicer in
maintaining any such insurance shall not, for the purpose of calculating monthly
distributions to the Certificateholders or remittances to the Trustee for their
benefit, be added to the principal balance of the Mortgage Loan, notwithstanding
that the terms of the Mortgage Loan so permit. Such costs shall be recoverable
by the Servicer out of late payments by the related Mortgagor or out of
Liquidation Proceeds to the extent and as otherwise permitted by Section 3.08
hereof. It is understood and agreed that no earthquake or other additional
insurance is to be required of any Mortgagor or maintained on property acquired
in respect of a Mortgage other than pursuant to such applicable laws and
regulations as shall at any time be in force and as shall require such
additional insurance. If the Mortgaged Property is located at the time of
origination of the Mortgage Loan in a federally designated special flood hazard
area and such area is participating in the national flood insurance program, the
Servicer shall cause flood insurance to be maintained with respect to such
Mortgage Loan. Such flood insurance shall be in an amount equal to the lesser of
(i) the original principal balance of the related Mortgage Loan, (ii) the
replacement value of the improvements that are part of such Mortgaged Property,
or (iii) the maximum amount of such insurance available for the related
Mortgaged Property under the Flood Disaster Protection Act of 1973, as amended.

      In the event that the Servicer shall obtain and maintain a blanket policy
insuring against hazard losses on all of the Mortgage Loans, it shall
conclusively be deemed to have satisfied its obligations as set forth in the
first sentence of this Section 3.10, it being understood and agreed that such
policy may contain a deductible clause on terms substantially equivalent to
those commercially available and maintained by comparable servicers. If such
policy contains a deductible clause, the Servicer shall, in the event that there
shall not have been maintained on the related Mortgaged Property a policy
complying with the first sentence of this Section 3.10, and there shall have
been a loss that would have been covered by such policy, deposit in the
Collection Account the amount not otherwise payable under the blanket policy
because of such deductible clause. In connection with its activities as servicer
of the Mortgage Loans, the Servicer agrees to present, on behalf of itself, the
Depositor and the Trustee for the benefit of the Certificateholders, claims
under any such blanket policy.

      SECTION 3.11. Enforcement of Due-On-Sale Clauses; Assumption Agreements.

      (a) Except as otherwise provided in this Section 3.11(a), when any
property subject to a Mortgage has been or is about to be conveyed by the
Mortgagor, the Servicer shall to the extent that it has knowledge of such
conveyance or prospective conveyance, enforce any due-on-sale clause contained
in any Mortgage Note or Mortgage, but only to the extent that such enforcement
will not adversely affect or jeopardize coverage under any Required Insurance
Policy; provided, however, that the Servicer shall not exercise any such right
if the due-on-sale clause, in the reasonable belief of the Servicer, is not
enforceable under applicable law. An opinion of counsel, which shall be
reimbursable as a Servicing Advance, delivered to the Trustee and the Depositor
to the foregoing shall conclusively establish the reasonableness of such belief
to the extent permitted under applicable law. Notwithstanding the foregoing, the
Servicer is not required to exercise such rights with respect to a Mortgage Loan
if the Person to whom the related Mortgaged Property has been conveyed or is
proposed to be conveyed

                                       68
<PAGE>

satisfies the terms and conditions contained in the Mortgage Note and Mortgage
related thereto and the consent of the mortgagee under such Mortgage Note or
Mortgage is not otherwise so required under such Mortgage Note or Mortgage as a
condition to such transfer. In the event that the Servicer is prohibited by law
from enforcing any such due-on-sale clause, or if coverage under any Required
Insurance Policy would be adversely affected, or if nonenforcement is otherwise
permitted hereunder, the Servicer is authorized, subject to Section 3.11(b), to
take or enter into an assumption and modification agreement from or with the
Person to whom such property has been or is about to be conveyed, pursuant to
which such Person becomes liable under the Mortgage Note and, unless prohibited
by applicable state law, the Mortgagor remains liable thereon, provided that the
Mortgage Loan shall continue to be covered (if so covered before the Servicer
enters such agreement) by the applicable Required Insurance Policies. The
Servicer, subject to Section 3.11(b), is also authorized with the prior approval
of the insurers under any Required Insurance Policies to enter into a
substitution of liability agreement with such Person, pursuant to which the
original Mortgagor is released from liability and such Person is substituted as
Mortgagor and becomes liable under the Mortgage Note. Notwithstanding the
foregoing, the Servicer shall not be deemed to be in default under this Section
3.11(a) by reason of any transfer or assumption that the Servicer reasonably
believes it is restricted by law from preventing.

      (b) Subject to the Servicer's duty to enforce any due-on-sale clause to
the extent set forth in Section 3.11(a) hereof, in any case in which a Mortgaged
Property has been conveyed to a Person by a Mortgagor, and such Person is to
enter into an assumption agreement or modification agreement or supplement to
the Mortgage Note or Mortgage that requires the signature of the Trustee, or if
an instrument of release signed by the Trustee is required releasing the
Mortgagor from liability on the Mortgage Loan, the Servicer shall prepare and
deliver or cause to be prepared and delivered to the Trustee for signature and
shall direct, in writing, the Trustee to execute the assumption agreement with
the Person to whom the Mortgaged Property is to be conveyed and such
modification agreement or supplement to the Mortgage Note or Mortgage or other
instruments as are reasonable or necessary to carry out the terms of the
Mortgage Note or Mortgage or otherwise to comply with any applicable laws
regarding assumptions or the transfer of the Mortgaged Property to such Person.
In connection with any such assumption, no material term of the Mortgage Note
(including, but not limited to, the Mortgage Rate, the amount of the Scheduled
Payment, the Maximum Rate, the Minimum Rate, the Gross Margin, the Periodic Rate
Cap, the Adjustment Date, any prepayment penalty and any other term affecting
the amount or timing of payment on the Mortgage Loan) may be changed. The
Servicer shall notify the Trustee and the NIM Insurer that any such substitution
or assumption agreement has been completed by forwarding to the Trustee (with a
copy to the NIM Insurer) the original of such substitution or assumption
agreement, which in the case of the original shall be added to the related
Mortgage File and shall, for all purposes, be considered a part of such Mortgage
File to the same extent as all other documents and instruments constituting a
part thereof. Any fee collected by the Servicer for entering into an assumption
or substitution of liability agreement will be retained by the Servicer as
additional servicing compensation.

      SECTION 3.12. Realization Upon Defaulted Mortgage Loans; Determination of
Excess Proceeds.

      (a) The Servicer shall use reasonable efforts consistent with the
servicing standard set forth in Section 3.01 to foreclose upon or otherwise
comparably convert the ownership of properties securing such of the Mortgage
Loans as come into and continue in default and as to which no satisfactory
arrangements can be made for collection of Delinquent payments. In connection
with such foreclosure or other conversion, the Servicer shall follow such
practices and procedures as it shall deem necessary or advisable and as shall be
normal and usual in its general mortgage servicing activities and the
requirements of the insurer under any Required Insurance Policy; provided,
however, that the Servicer shall not be required to expend its own funds in
connection with the restoration of any property that shall have suffered damage
due to an uninsured cause unless it shall determine (i) that such restoration
will

                                       69
<PAGE>

increase the proceeds of liquidation of the Mortgage Loan after reimbursement to
itself of such expenses and (ii) that such expenses will be recoverable to it
through Liquidation Proceeds (respecting which it shall have priority for
purposes of withdrawals from the Collection Account pursuant to Section 3.08
hereof). The Servicer shall be responsible for all other costs and expenses
incurred by it in any such proceedings; provided, however, that it shall be
entitled to reimbursement thereof from the proceeds of liquidation of the
related Mortgaged Property, as contemplated in Section 3.08 hereof. If the
Servicer has knowledge that a Mortgaged Property that the Servicer is
contemplating acquiring in foreclosure or by deed-in-lieu of foreclosure is
located within a one-mile radius of any site with environmental or hazardous
waste risks known to the Servicer, the Servicer will, prior to acquiring the
Mortgaged Property, consider such risks and only take action in accordance with
Accepted Servicing Practices.

      With respect to any REO Property, the deed or certificate of sale shall be
taken in the name of the Trustee or its nominee. Pursuant to its efforts to sell
such REO Property, the Servicer shall either itself or through an agent selected
by the Servicer protect and conserve such REO Property in the same manner and to
such extent as is customary in the locality where such REO Property is located
and may, incident to its conservation and protection of the interests of the
Certificateholders, rent the same, or any part thereof, as the Servicer deems to
be in the best interest of the Servicer and the Certificateholders for the
period prior to the sale of such REO Property. The Servicer or an affiliate may
receive usual and customary real estate referral fees for real estate brokers in
connection with the listing and disposition of REO Property. The Servicer shall
prepare a statement with respect to each REO Property that has been rented
showing the aggregate rental income received and all expenses incurred in
connection with the management and maintenance of such REO Property at such
times as is necessary to enable the Servicer to comply with the reporting
requirements of the REMIC Provisions. The net monthly rental income, if any,
from such REO Property shall be deposited in the Collection Account no later
than the close of business on each Determination Date. The Servicer shall
perform the tax reporting and withholding related to foreclosures, abandonments
and cancellation of indebtedness income as specified by Sections 1445, 6050J and
6050P of the Code by preparing and filing such tax and information returns, as
may be required.

      In the event that the Trust Fund acquires any Mortgaged Property as
aforesaid or otherwise in connection with a default or imminent default on a
Mortgage Loan, the Servicer shall dispose of such Mortgaged Property prior to
the expiration of three years from the end of the year of its acquisition by the
Trust Fund or, at the expense of the Trust Fund, obtain more than 60 days prior
to the day on which such three-year period would otherwise expire, an extension
of the three-year grace period unless the Trustee and the NIM Insurer shall have
been supplied with an Opinion of Counsel addressed to the Trustee and the NIM
Insurer (such Opinion of Counsel not to be an expense of the Trustee or the NIM
Insurer) to the effect that the holding by the Trust Fund of such Mortgaged
Property subsequent to such three-year period will not result in the imposition
of taxes on "prohibited transactions" of the Trust Fund or any of the REMICs
provided for herein as defined in section 860F of the Code or cause any of the
REMICs provided for herein to fail to qualify as a REMIC at any time that any
Certificates are outstanding, in which case the Trust Fund may continue to hold
such Mortgaged Property (subject to any conditions contained in such Opinion of
Counsel). Notwithstanding any other provision of this Agreement, no Mortgaged
Property acquired by the Trust Fund shall be held, rented (or allowed to
continue to be rented) or otherwise used for the production of income by or on
behalf of the Trust Fund in such a manner or pursuant to any terms that would
(i) cause such Mortgaged Property to fail to qualify as "foreclosure property"
within the meaning of section 860G(a)(8) of the Code or (ii) subject the Trust
Fund or any REMIC provided for herein to the imposition of any federal, state or
local income taxes on the income earned from such Mortgaged Property under
section 860G(c) of the Code or otherwise, unless the Servicer or the Depositor
has agreed to indemnify and hold harmless the Trust Fund with respect to the
imposition of any such taxes.

                                       70
<PAGE>

      The decision of the Servicer to foreclose on a defaulted Mortgage Loan
shall be subject to a determination by the Servicer that the proceeds of such
foreclosure would exceed the costs and expenses of bringing such a proceeding.
The income earned from the management of any Mortgaged Properties acquired
through foreclosure or other judicial proceeding, net of reimbursement to the
Servicer for expenses incurred (including any property or other taxes) in
connection with such management and net of unreimbursed Servicing Fees,
Advances, Servicing Advances and any management fee paid or to be paid with
respect to the management of such Mortgaged Property, shall be applied to the
payment of principal of, and interest on, the related defaulted Mortgage Loans
(with interest accruing as though such Mortgage Loans were still current) and
all such income shall be deemed, for all purposes in this Agreement, to be
payments on account of principal and interest on the related Mortgage Notes and
shall be deposited into the Collection Account. To the extent the income
received during a Prepayment Period is in excess of the amount attributable to
amortizing principal and accrued interest at the related Mortgage Rate on the
related Mortgage Loan, such excess shall be considered to be a partial Principal
Prepayment for all purposes hereof.

      The Liquidation Proceeds from any liquidation of a Mortgage Loan, net of
any payment to the Servicer as provided above, shall be deposited in the
Collection Account on the next succeeding Determination Date following receipt
thereof for distribution on the related Distribution Date.

      The proceeds of any Liquidated Loan, as well as any recovery resulting
from a partial collection of Liquidation Proceeds or any income from an REO
Property, will be applied in the following order of priority: first, to
reimburse the Servicer for any related unreimbursed Servicing Advances and
Servicing Fees, pursuant to Section 3.08(a)(vi) or this Section 3.12; second, to
reimburse the Servicer for any unreimbursed Advances, pursuant to Section
3.08(a)(ii) or this Section 3.12; third, to any prepayment penalties and then to
accrued and unpaid interest (to the extent no Advance has been made for such
amount) on the Mortgage Loan or related REO Property, at the Net Mortgage Rate
to the Due Date occurring in the month in which such amounts are required to be
distributed; and fourth, as a recovery of principal of the Mortgage Loan.

      (b) On each Determination Date, the Servicer shall determine the
respective aggregate amounts of Excess Proceeds, if any, that occurred in the
related Prepayment Period.

      (c) The Servicer, in its sole discretion, shall have the right to elect
(by written notice sent to the Trustee) to purchase for its own account from the
Trust Fund any Mortgage Loan that is 91 days or more Delinquent or REO Property
for which the Servicer has accepted a deed-in-lieu of foreclosure at a price
equal to the Purchase Price. The Purchase Price for any Mortgage Loan or REO
Property purchased hereunder shall be delivered to the Trustee for deposit in
the Collection Account and the Trustee, upon receipt of such deposit and a
Request for Release from the Depositor in the form of Exhibit I hereto, shall
release or cause to be released to the Servicer the related Mortgage File and
shall execute and deliver such instruments of transfer or assignment prepared by
the Servicer, in each case without recourse, representation or warranty, as
shall be necessary to vest in the Servicer any Mortgage Loan or REO Property
released pursuant hereto and the Servicer shall succeed to all the Trustee'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 Servicer shall thereupon own such Mortgage Loan or REO
Property, and all security and documents, free of any further obligation to the
Trustee or the Certificateholders with respect thereto. The Servicer shall not
use any procedure in selecting Mortgage Loans to be repurchased which is
materially adverse to the interests of the Certificateholders.

      In the event that the Servicer is acting as the servicer and the Servicer
(or an affiliate of the Servicer) is the owner of more than 50% of the Class of
Certificates which is then currently in a first loss position and such party is
deemed to be the "Primary Beneficiary" as defined in FIN 40, the provisions of

                                       71
<PAGE>

the preceding paragraph shall not apply and the Servicer (or an affiliate of the
Servicer), in its sole discretion, shall have the right to elect to purchase for
its own account from the Trust Fund any Mortgage Loan that is 120 days or more
Delinquent or REO Property for which the Servicer has accepted a deed-in-lieu of
foreclosure, during the period commencing on the first day of the calendar
quarter succeeding the calendar quarter in which the Initial Delinquency Date
(as defined below) occurred with respect to such Mortgage Loan and ending on the
last Business Day of such calendar quarter. If the Servicer (or an affiliate of
the Servicer) does not exercise its purchase right with respect to a Mortgage
Loan during the period specified in the preceding sentence, such Mortgage Loan
shall thereafter again become eligible for purchase pursuant to the preceding
sentence only after the Mortgage Loan ceases to be 120 days or more Delinquent
and thereafter becomes 120 days Delinquent again. The "Initial Delinquency Date"
of a Mortgage Loan shall mean the date on which the Mortgage Loan first became
120 days Delinquent. Prior to repurchase pursuant to this Section 3.12, the
Servicer shall be required to continue to make monthly advances pursuant to
Section 4.01. The Servicer shall not use any procedure in selecting Mortgage
Loans to be repurchased which is materially adverse to the interests of the
Certificateholders. The Servicer purchase any Mortgage Loan or REO Property
pursuant to this paragraph at a price equal to the Purchase Price. The Purchase
Price for any Mortgage Loan or REO Property purchased hereunder shall be
delivered to the Trustee for deposit in the Collection Account and the Trustee,
upon receipt of such deposit and a Request for Release from the Depositor in the
form of Exhibit I hereto, shall release or cause to be released to the Servicer
the related Mortgage File and shall execute and deliver such instruments of
transfer or assignment prepared by the Servicer, in each case without recourse,
representation or warranty, as shall be necessary to vest in the Servicer any
Mortgage Loan or REO Property released pursuant hereto and the Servicer shall
succeed to all the Trustee's right, title and interest in and to such Mortgage
Loan and all security and documents related thereto. The provisions in this
paragraph shall only apply if Litton Loan Servicing LP is the servicer.

      (d) The Servicer may write-off any second lien Mortgage Loan that has been
Delinquent for a period of 180 days or more, provided that the Servicer has
certified in a certificate of an officer of the Servicer delivered to the
Depositor and the Trustee that it does not believe that there is a reasonable
likelihood that any further net proceeds will be received or recovered with
respect to such Mortgage Loan.

      SECTION 3.13. Trustee to Cooperate; Release of Mortgage Files.

      Upon the payment in full of any Mortgage Loan, or the receipt by the
Servicer of a notification that payment in full will be escrowed in a manner
customary for such purposes, the Servicer will promptly notify the Trustee or
its designee by delivering a Request for Release substantially in the form of
Exhibit I. Upon receipt of such request, the Trustee or its designee shall
promptly release the related Mortgage File to the Servicer, and the Trustee or
its designee shall at the Servicer's written direction execute and deliver to
the Servicer the request for reconveyance, deed of reconveyance or release or
satisfaction of mortgage or such instrument releasing the lien of the Mortgage
in each case provided by the Servicer, together with the Mortgage Note with
written evidence of cancellation thereon. No expenses incurred in connection
with any instrument of satisfaction or deed of reconveyance shall be chargeable
to the Collection Account, the Certificate Account or the related subservicing
account. From time to time and as shall be appropriate for the servicing or
foreclosure of any Mortgage Loan, including for such purpose, collection under
any policy of flood insurance, any fidelity bond or errors or omissions policy,
or for the purposes of effecting a partial release of any Mortgaged Property
from the lien of the Mortgage or the making of any corrections to the Mortgage
Note or the Mortgage or any of the other documents included in the Mortgage
File, the Trustee or its designee shall, upon delivery to the Trustee or its
designee of a Request for Release in the form of Exhibit I signed by a Servicing
Officer, release the Mortgage File to the Servicer. Subject to the further
limitations set forth below, the Servicer shall cause the Mortgage File or
documents so released to be returned to the Trustee or its designee when the
need

                                       72
<PAGE>

therefor by the Servicer no longer exists, unless the Mortgage Loan is
liquidated and the proceeds thereof are deposited in the Collection Account, in
which case the Trustee or its designee shall deliver the Request for Release to
the Servicer.

      Each Request for Release may be delivered to the Trustee or its designee
(i) via mail or courier, (ii) via facsimile or (iii) by such other means,
including, without limitation, electronic or computer readable medium, as the
Servicer and the Trustee or its designee shall mutually agree. The Trustee or
its designee shall promptly release the related Mortgage File(s) within five (5)
Business Days of receipt of a properly completed Request for Release pursuant to
clauses (i), (ii) or (iii) above. Receipt of a properly completed Request for
Release shall be authorization to the Trustee or its designee to release such
Mortgage Files, provided the Trustee or its designee has determined that such
Request for Release has been executed, with respect to clauses (i) or (ii)
above, or approved, with respect to clause (iii) above, by an authorized
Servicing Officer of the Servicer, and so long as the Trustee or its designee
complies with its duties and obligations under the agreement. If the Trustee or
its designee is unable to release the Mortgage Files within the period
previously specified, the Trustee or its designee shall immediately notify the
Servicer indicating the reason for such delay. If the Servicer is required to
pay penalties or damages due to the Trustee or its designee's negligent failure
to release the related Mortgage File or the Trustee or its designee's negligent
failure to execute and release documents in a timely manner, the Trustee or its
designee, shall be liable for such penalties or damages directly caused by it
and shall have no liability for penalties or damages attributable to the
Servicer's actions or inactions.

      If the Servicer at any time seeks to initiate a foreclosure proceeding in
respect of any Mortgaged Property as authorized by this Agreement, the Servicer
shall deliver or cause to be delivered to the Trustee or its designee, for
signature, as appropriate, any court pleadings, requests for trustee's sale or
other documents necessary to effectuate such foreclosure or any legal action
brought to obtain judgment against the Mortgagor on the Mortgage Note or the
Mortgage or to obtain a deficiency judgment or to enforce any other remedies or
rights provided by the Mortgage Note or the Mortgage or otherwise available at
law or in equity. Notwithstanding the foregoing, the Servicer shall cause
possession of any Mortgage File or of the documents therein that shall have been
released by the Trustee or its designee to be returned to the Trustee promptly
after possession thereof shall have been released by the Trustee or its designee
unless (i) the Mortgage Loan has been liquidated and the Liquidation Proceeds
relating to the Mortgage Loan have been deposited in the Collection Account, and
the Servicer shall have delivered to the Trustee or its designee a Request for
Release in the form of Exhibit I or (ii) the Mortgage File or document shall
have been delivered to an attorney or to a public trustee or other public
official as required by law for purposes of initiating or pursuing legal action
or other proceedings for the foreclosure of the Mortgaged Property and the
Servicer shall have delivered to the Trustee or its designee an Officer's
Certificate of a Servicing Officer certifying as to the name and address of the
Person to which the Mortgage File or the documents therein were delivered and
the purpose or purposes of such delivery.

      SECTION 3.14. Documents Records and Funds in Possession of Servicer to be
Held for the Trustee.

      All Mortgage Files and funds collected or held by, or under the control
of, the Servicer in respect of any Mortgage Loans, whether from the collection
of principal and interest payments or from Liquidation Proceeds, including but
not limited to, any funds on deposit in the Collection Account, shall be held by
the Servicer for and on behalf of the Trustee and shall be and remain the sole
and exclusive property of the Trustee, subject to the applicable provisions of
this Agreement. The Servicer also agrees that it shall not create, incur or
subject any Mortgage File or any funds that are deposited in the Collection
Account or Certificate Account or in any Escrow Account, or any funds that
otherwise are or may become due or payable to the Trustee for the benefit of the
Certificateholders, to any claim, lien, security interest, judgment, levy, writ
of attachment or other encumbrance, or assert by legal action or otherwise any
claim

                                       73

or right of set off against any Mortgage File or any funds collected on, or in

entitled to set off against and deduct from any such funds any amounts that are
properly due and payable to the Servicer under this Agreement.

      SECTION 3.15. Servicing Compensation.

      As compensation for its activities hereunder, the Servicer shall be
entitled to retain or withdraw from the Collection Account out of each payment
of interest on a Mortgage Loan included in the Trust Fund an amount equal to
interest at the applicable Servicing Fee Rate on the Stated Principal Balance of
the related Mortgage Loan as of the immediately preceding Distribution Date.

      Additional servicing compensation in the form of any Excess Proceeds, late
payment fees, customary real estate referral fees, assumption fees (i.e. fees
related to the assumption of a Mortgage Loan upon the purchase of the related
Mortgaged Property) and similar fees payable by the Mortgagor, and all income
and gain net of any losses realized from Permitted Investments in the Collection
Account shall be retained by the Servicer to the extent not required to be

with its servicing activities hereunder (including payment of any premiums for
hazard insurance, as required by Section 3.10 hereof and maintenance of the
other forms of insurance coverage required by Section 3.10 hereof) and shall not
be entitled to reimbursement therefor except as specifically provided in
Sections 3.08 and 3.12 hereof.

      SECTION 3.16. Access to Certain Documentation.

      The Servicer shall provide to the OTS and the FDIC and to comparable
regulatory authorities supervising Holders of the Certificates and the examiners
and supervisory agents of the OTS, the FDIC and such other authorities, access
to the documentation regarding the Mortgage Loans required by applicable
regulations of the OTS and the FDIC. Such access shall be afforded without
charge, but only upon reasonable and prior written request and during normal
business hours at the offices of the Servicer designated by it provided, that
the Servicer shall be entitled to be reimbursed by each such Certificateholder
for actual expenses incurred by the Servicer in providing such reports and
access. Nothing in this Section shall limit the obligation of the Servicer to
observe any applicable law prohibiting disclosure of information regarding the
Mortgagors and the failure of the Servicer to provide access as provided in this
Section as a result of such obligation shall not constitute a breach of this
Section.

      SECTION 3.17. Annual Statement as to Compliance.

the Trustee and the NIM insurer on or before March 15 beginning in 2005 or such

of in order to remain in compliance with the Section 302 Requirements, an
Officer's Certificate stating, as to each signatory thereof, that (i) a review

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 forward a copy of each such statement

accountants (who may also render other services to the Servicer or any Affiliate
thereof) that is a member of the American Institute of Certified Public
Accountants to furnish a USAP Report to the Trustee, the NIM Insurer and the

pursuant to the Indenture remain outstanding or the NIM Insurer is owed amounts
in respect of its guarantee of payment on such notes.

      SECTION 3.20. Periodic Filings.

      (a) Promptly upon receipt of (i) any report of the independent public
accountants required pursuant to Section 3.18, and (ii) the Officer's

Servicer's performance of its obligations under this Agreement, the Trustee
shall include such report and such certificate as part of the Form 10-K required
to be filed pursuant to the terms of this Agreement.

      (b) The Trustee shall prepare for filing, and execute (other than the Form
10-Ks and the Certification), on behalf of the Trust Fund, and file with the
Securities and Exchange Commission, (i) within 15 days after each Distribution

Requirements, and (iii) any and all reports, statements and information
respecting the Trust Fund and/or the Certificates required to be filed on behalf
of the Trust Fund under the Exchange Act executed by the Trustee. The
Certification shall be executed by a senior officer of the Depositor. Upon such
filing with the Securities and Exchange Commission, the Trustee shall promptly
deliver to the Depositor a copy of any such executed report, statement or

as it is able to do so pursuant to applicable law. The Depositor hereby grants
to the Trustee a limited power of attorney to execute (other than the Form 10-Ks
and the Certification) and file each such document on behalf of the Depositor.
Such power of attorney shall continue until either the earlier of (i) receipt by
the Trustee from the Depositor of written termination of such power of attorney
and (ii) the termination of the Trust Fund. The Depositor agrees to promptly
furnish to the Trustee, from time to time upon request, such further
information, reports, and financial statements within its control related to
this Agreement and the Mortgage Loans as the Trustee reasonably deems
appropriate to prepare and file all necessary reports with the Commission. The
Trustee shall have no responsibility to file any items other than those
specified in this section.

      (c) [RESERVED].

                                       75
<PAGE>

      (d) The obligations set forth in paragraphs (a) through (c) of this
Section shall only apply with respect to periods for which the Trustee is
obligated to file Form 8-Ks and 10-Ks pursuant to paragraph (b) of this Section.
In the event a Form 15 is properly filed pursuant to paragraph (b) of this
Section, there shall be no further obligations under paragraphs (a) through (c)
of this Section commencing with the fiscal year in which the Form 15 is filed
(other than the obligations in paragraphs (a) and (b) of this Section to be
performed in such fiscal year that relate back to the prior fiscal year).

      SECTION 3.21. Annual Certificate by Trustee.

      (a) Within 15 days prior to the date on which a Form 10-K is to be filed
with a Certification by the Depositor, an officer of the Trustee shall execute
and deliver an Officer's Certificate, signed by a Responsible Officer of the
Trustee or any officer to whom that officer reports, to the Depositor for the
benefit of such Depositor and its officers, directors and affiliates, certifying
as to the matters described in the Officer's Certificate attached hereto as
Exhibit K.

      (b) The Trustee shall indemnify and hold harmless the Depositor and its
officers, directors, agents and affiliates from and against any losses, damages,
penalties, fines, forfeitures, reasonable legal fees and related costs,
judgments and other costs and expenses arising out of or based upon a breach by
the Trustee or any of its officers, directors, agents or affiliates of its
obligations under this Section 3.21 any material misstatement or omission in the
Officer's Certificate required under this Section or the negligence, bad faith
or willful misconduct of the Trustee in connection therewith. If the
indemnification provided for herein is unavailable or insufficient to hold
harmless the Depositor, then the Trustee agrees that it shall contribute to the
amount paid or payable by the Depositor as a result of the losses, claims,
damages or liabilities of the Depositor in such proportion as is appropriate to
reflect the relative fault of the Trustee on the one had and the Depositor on
the other in connection with a breach of the Trustee's obligations under this
Section 3.21, any material misstatement or omission in the Officer's Certificate
required under this Section or the Trustee's negligence, bad faith or willful
misconduct in connection therewith.

      SECTION 3.22. Annual Certificate by Servicer.

      (a) By February 28 beginning in 2005 or such other date specified in a
written notice within 15 days prior to the date on which a Form 8-K is required
to be filed with a Certification by the Depositor, the Servicer shall execute
and deliver an Officer's Certificate in the form of Exhibit L attached hereto,
signed by the senior officer in charge of servicing of the Servicer or any
officer to whom that officer reports, to the Trustee, the NIM Insurer and
Depositor for the benefit of the Trustee and Depositor and their respective

            (i) The Servicer has reviewed the information required to be
      delivered to the Trustee pursuant to the Pooling and Servicing Agreement
      (the "Servicing Information").

            (ii) Based on the Servicer's knowledge, the information in the
      Annual Statement of Compliance and the Servicing Information does not
      contain any untrue statement of a material fact or omit to state a
      material fact necessary to make any such reports, certificates or other
      information, in light of the circumstances under which such statements
      were made, not misleading as of the last day of the period covered by the
      Annual Statement of Compliance;

            (iii) Based on the Servicer's knowledge, the Servicing Information
      required to be provided to the Trustee by the Servicer under this
      Agreement has been provided to the Trustee; and

                                       76
<PAGE>

            (iv) Based upon the review required under this Agreement, and except
      as disclosed in the Annual Statement of Compliance, the Annual Independent
      Certified Public Accountant's Servicing Report and all servicing reports,
      officer's certificates and other information relating to the servicing of
      the Mortgage Loans submitted to the Trustee by the Servicer, the Servicer
      has, as of the last day of the period covered by the Annual Statement of
      Compliance fulfilled its obligations under this Agreement.

      (b) The Servicer shall indemnify and hold harmless the Depositor and their
respective officers, directors, agents and affiliates from and against (i) any
losses, damages, penalties, fines, forfeitures, reasonable legal fees and
related costs, judgments and other costs and expenses arising out of or based

a material fact or omits or omitted to state a material fact necessary to make
the statements made, in light of the circumstances under which such statements
were made, not misleading or (iii) the negligence, bad faith or willful
misconduct of the Servicer in connection therewith. If the indemnification
provided for herein is unavailable or insufficient to hold harmless the
Depositor, then the Servicer agrees that it shall contribute to the amount paid

damages or liabilities of the Depositor in such proportion as is appropriate to
reflect the relative fault of the Depositor on the one hand and the Servicer on
the other in connection with a breach of the Servicer's obligations under this
Section 3.22, any alleged material misstatement or omission in the Officer's
Certificate required under this Section or the Servicer's negligence, bad faith
or willful misconduct in connection therewith.

            (iv) original principal balance;

            (v) prepayment penalty amount due;

            (vii) reason why full prepayment penalty amount was not collected,
      if applicable.

                                       77
<PAGE>

      SECTION 3.24. Statements to Trustee. Not later than the tenth calendar day
of each month, the Servicer shall furnish to the Trustee and the NIM Insurer an
electronic file providing loan level accounting data for the period ending on
the last Business Day of the preceding month in the format mutually agreed upon
between the Servicer and the Trustee, including but not limited to information
described in Section 4.05(a).

      SECTION 3.25. Indemnification.

      The Servicer shall indemnify the Seller, the Trust Fund, Trustee, the
Depositor and the NIM Insurer and hold each of them harmless against any and all
claims, losses, damages, penalties, fines, forfeitures, reasonable and necessary
legal fees and related costs, judgments, and any other costs, fees and expenses
that any of such parties may sustain in any way related to the failure of the
Servicer to perform its duties and service the Mortgage Loans in compliance with
the terms of this Agreement. The Servicer immediately shall notify the Seller,
the Trustee, the Depositor and the NIM Insurer or any other relevant party if a
claim is made by a third party with respect to this Agreement or the Mortgage
Loans, assume (with the prior written consent of the indemnified party, which
consent shall not be unreasonably withheld or delayed) the defense of any such
claim and pay all expenses in connection therewith, including counsel fees, and
promptly pay, discharge and satisfy any judgment or decree which may be entered
against it or any of such parties in respect of such claim. The Servicer shall
follow any written instructions received from the Trustee and the NIM Insurer in
connection with such claim. The Servicer shall provide the Trustee, the
Depositor and the NIM Insurer with a written report of all expenses and advances
incurred by the Servicer pursuant to this Section 3.25, and the Servicer from
the assets of the Trust Fund in the Collection Account promptly shall reimburse
itself for all amounts advanced by it pursuant to the preceding sentence except
when the claim in any way relates to the failure of the Servicer to service and
administer the Mortgage Loans in material compliance with the terms of this
Agreement or the gross negligence, bad faith or willful misconduct of the
Servicer. The provisions of this paragraph shall survive the termination of this
Agreement and the payment of the outstanding Certificates.

      SECTION 3.26. Nonsolicitation.

      For as long as the Servicer services the Mortgage Loans, the Servicer
covenants that it will not, and that it will ensure that its affiliates and
agents, will not, directly solicit or provide information for any other party to
solicit for prepayment or refinancing of any of the Mortgage Loans by the
related Mortgagors. It is understood that the promotions undertaken by the
Servicer which are directed to the general public at large, or certain segments
thereof, shall not constitute solicitation as that term is used in this Section
3.26.

      SECTION 3.27. Existing Servicing Agreement.

      The Servicer acknowledges the transfer on the Closing Date of the
servicing of the Mortgage Loans from the Existing Servicing Agreement to this
Agreement pursuant to Section 10.01 of the Existing Servicing Agreement.

                                   ARTICLE IV
                                  DISTRIBUTIONS

      SECTION 4.01. Advances.

      Subject to the conditions of this Article IV, the Servicer, as required
below, shall make an Advance and deposit such Advance in the Collection Account.
Each such Advance shall be remitted to the Collection Account no later than 1:00
p.m. New York City time on the Servicer Advance Date in

                                       78
<PAGE>

immediately available funds. The Servicer shall be obligated to make any such
Advance only to the extent that such advance would not be a Non-Recoverable
Advance. If the Servicer shall have determined that it has made a
Non-Recoverable Advance or that a proposed Advance or a lesser portion of such
Advance would constitute a Non-Recoverable Advance, the Servicer shall deliver
(i) to the Trustee for the benefit of the Certificateholders funds constituting
the remaining portion of such Advance, if applicable, and (ii) to the Depositor,
the NIM Insurer, each Rating Agency and the Trustee an Officer's Certificate
setting forth the basis for such determination. The Servicer may, in its sole
discretion, make an Advance with respect to the principal portion of the final
Scheduled Payment on a Balloon Loan, but the Servicer is under no obligation to
do so; provided, however, that nothing in this sentence shall affect the
Servicer's obligation under this Section 4.01 to Advance the interest portion of
the final Scheduled Payment with respect to a Balloon Loan as if such Balloon
Loan were a fully amortizing Mortgage Loan. If a Mortgagor does not pay its
final Scheduled Payment on a Balloon Loan when due, the Servicer shall Advance
(unless it determines in its good faith judgment that such amounts would
constitute a Non Recoverable Advance) a full month of interest (net of the
Servicing Fee) on the Stated Principal Balance thereof each month until its
Stated Principal Balance is reduced to zero.

      In lieu of making all or a portion of such Advance from its own funds, the
Servicer may (i) cause to be made an appropriate entry in its records relating
to the Collection Account that any amount held for future distribution has been
used by the Servicer in discharge of its obligation to make any such Advance and
(ii) transfer such funds from the Collection Account to the Certificate Account.
In addition, the Servicer shall have the right to reimburse itself for any such
Advance from amounts held from time to time in the Collection Account to the
extent such amounts are not then required to be distributed. Any funds so
applied and transferred pursuant to the previous two sentences shall be replaced
by the Servicer by deposit in the Collection Account no later than the close of
business on the Servicer Advance Date on which such funds are required to be
distributed pursuant to this Agreement. The Servicer shall be entitled to be
reimbursed from the Collection Account for all Advances of its own funds made
pursuant to this Section as provided in Section 3.08. The obligation to make
Advances with respect to any Mortgage Loan shall continue until such Mortgage
Loan is paid in full or the related Mortgaged Property or related REO Property
has been liquidated or until the purchase or repurchase thereof (or substitution
therefor) from the Trust Fund pursuant to any applicable provision of this
Agreement, except as otherwise provided in this Section 4.01.

      SECTION 4.02. Reduction of Servicing Compensation in Connection with
Prepayment Interest Shortfalls.

      In the event that any Mortgage Loan is the subject of a Prepayment
Interest Shortfall, the Servicer shall, from amounts in respect of the Servicing
Fee for such Distribution Date, deposit into the Collection Account, as a
reduction of the Servicing Fee for such Distribution Date, no later than the
Servicer Advance Date immediately preceding such Distribution Date, an amount up
to the Prepayment Interest Shortfall; provided that the amount so deposited with
respect to any Distribution Date shall be limited to the product of (x)
one-twelfth of 0.30% and (y) the aggregate Stated Principal Balance of the
Mortgage Loans. In case of such deposit, the Servicer shall not be entitled to
any recovery or reimbursement from the Depositor, the Trustee, the Trust Fund or
the Certificateholders. With respect to any Distribution Date, to the extent
that the Prepayment Interest Shortfall exceeds Compensating Interest (such
excess, a "Non-Supported Interest Shortfall"), such Non-Supported Interest
Shortfall shall reduce the Current Interest with respect to each Class of
Certificates, pro rata based upon the amount of interest each such Class would
otherwise be entitled to receive on such Distribution Date. Notwithstanding the
foregoing, there shall be no reduction of the Servicing Fee in connection with
Prepayment Interest Shortfalls related to the Relief Act and the Servicer shall
not be obligated to pay Compensating Interest with respect to Prepayment
Interest Shortfalls related to the Relief Act.

<PAGE>

      SECTION 4.03. Distributions on the REMIC Interests.

      On each Distribution Date, amounts on deposit in the Certificate Account
shall be treated for federal income tax purposes as applied to distributions on
the interests in the Lower Tier REMIC in an amount sufficient to make the
distributions on the respective Certificates on such Distribution Date in
accordance with the provisions of Section 4.04.

      SECTION 4.04. Distributions.

      (a) [RESERVED].

      (b) On each Distribution Date, the Trustee shall make the following
            distributions from the Certificate Account of an amount equal to the
            Interest Funds in the following order of priority:

            (i) to the Class P Certificates, any prepayment penalties collected
      on the Mortgage Loans and (A) any amounts paid by the Seller or the
      Servicer in respect of prepayment charges pursuant to this Agreement or
      (B) any amounts received in respect of any indemnification paid as a
      result of a prepayment charge being unenforceable in breach of the
      representations and warranties set forth in the Sale Agreement received
      during the related Prepayment Period;

            (ii) to each Class of the Class R and Class A Certificates, the
      Current Interest and any Interest Carry Forward Amount with respect to
      each such Class; provided, however, if such amount is not sufficient to
      make a full distribution of the Current Interest and any Interest Carry
      Forward Amount to each of the Class R and Class A Certificates, such
      amount will be distributed pro rata among each Class of the Class R and
      Class A Certificates based on the ratio of (x) the Current Interest and
      Interest Carry Forward Amount for such Class to (y) the total amount of
      Current Interest and any Interest Carry Forward Amount for the Class R and
      Class A Certificates in the aggregate;

            (iii) to the Class M-1 Certificates, the Current Interest and any
      Interest Carry Forward Amount for such class;

            (iv) to the Class M-2 Certificates, the Current Interest and any
      Interest Carry Forward Amount for such class;

            (v) to the Class M-3 Certificates, the Current Interest and any
      Interest Carry Forward Amount for such class;

            (vi) to the Class B-1 Certificates, the Current Interest and any
      Interest Carry Forward Amount for such class;

            (vii) to the Class B-2 Certificates, the Current Interest and any
      Interest Carry Forward Amount for such class;

            (viii) to the Class B-3 Certificates, the Current Interest and any
      Interest Carry Forward Amount for such class; and

            (ix) any remainder pursuant to Section 4.04(e) hereof.

      On each Distribution Date, subject to the proviso in (ii) above, Interest
Funds received on the Group One Mortgage Loans will be deemed to be distributed
to the Class R and Class A-1 Certificates

                                       80
<PAGE>

and Interest Funds received on the Group Two Mortgage Loans will be deemed to be
distributed to the Class A-2 Certificates, in each case, until the related
Current Interest and Interest Carry Forward Amount of each such class of
Certificates for such Distribution Date has been paid in full. Thereafter,
Interest Funds not required for such distributions are available to be applied
to if necessary, to the class or classes of Certificates that are not related to
such group of Mortgage Loans.

      (c) All amounts representing prepayment charges in respect of the Mortgage
Loans, and amounts paid by the Servicer in respect of prepayment charges
pursuant to this Agreement will be distributed by the Trustee to the Holders of
the Class P Certificates pursuant to Section 4.04(b).

      (d) On each Distribution Date, the Trustee shall make the following
distributions from the Certificate Account of an amount equal to the Principal
Distribution Amount in the following order of priority, and each such
distribution shall be made only after all distributions pursuant to Section
4.04(b) above shall have been made until such amount shall have been fully
distributed for such Distribution Date:

            (i) to the Class A and Class R Certificates, the Class A Principal
      Distribution Amount shall be distributed as follows:

                  (a) the Group One Principal Distribution Amount shall be
                  distributed as follows: (I) if a Class A-1 Trigger Event has
                  occurred, the Group One Principal Distribution Amount shall be
                  distributed sequentially to the Class R, Class A-1A and Class
                  A-1B Certificates, until the Certificate Principal Balance of
                  each such Class has been reduced to zero and (II) if no Class
                  A-1 Trigger Event has occurred, the Group One Principal
                  Distribution Amount will be distributed as follows: first, to
                  the Class R Certificate until its Certificate Principal
                  Balance has been reduced to zero, and second, pro rata to the
                  Class A-1A and Class A-1B Certificates, based on their
                  relative Certificate Principal Balances, until the Certificate
                  Principal Balance of each such Class has been reduced to zero;
                  and

                  (b) the Group Two Principal Distribution Amount will be
                  distributed sequentially to the Class A-2A, Class A-2B and
                  Class A-2C Certificates until the Certificate Principal
                  Balance of each such Class has been reduced to zero; provided,
                  however, that on and after the Distribution Date on which the

                  Certificate Principal Balances have been reduced to zero, with
                  the exception that if a Class A-2A Accelerated Amortization
                  Event is also in effect, principal distributions to the Class
                  A-2A, Class A-2B and Class A-2C Certificates will be made
                  first, to the Class A-2A Certificates, until their Certificate

                  between the Class A-2B and Class A-2C Certificates, until

      (i) Subject to Section 9.02 hereof respecting the final distribution, on
each Distribution Date the Trustee shall make distributions to each
Certificateholder of record on the preceding Record Date either by wire transfer
in immediately available funds to the account of such holder at a bank or other
entity having appropriate facilities therefor, if such Holder has so notified
the Trustee at least five (5) Business Days prior to the related Record Date or,
if not, by check mailed by first class mail to such Certificateholder at the
address of such holder appearing in the Certificate Register. Notwithstanding
the foregoing, but subject to Section 9.02 hereof respecting the final
distribution, distributions with respect to Certificates registered in the name
of a Depository shall be made to such Depository in immediately available funds.

      (j) The Trustee is hereby directed by the Depositor to execute the Cap
Contracts on behalf of the Trust Fund in the form presented to it by the
Depositor and shall have no responsibility for the contents of such Cap
Contract, including, without limitation, the representations and warranties
contained therein. Any funds payable by the Trustee under the Cap Contracts at
closing shall be paid by the Depositor. Notwithstanding anything to the contrary
contained herein or in the Cap Contract, the Trustee shall not be required to
make any payments to the counterparty under the Cap Contract. Any payments
received under the terms of the related Cap Contract will be available to pay
the holders of the related Offered Certificates up to the amount of any Floating
Rate Certificate Carryovers remaining after all other

                                       83
<PAGE>

distributions required under this Section 4.04 are made on such Distribution
Date, other than Floating Rate Certificate Carryovers attributable to the fact
that Applied Realized Loss Amounts are not allocated to the Class A and Class R
Certificates. Any amounts received under the terms of any Cap Contract on a
Distribution Date that are not used to pay such Floating Rate Certificate
Carryovers will be distributed to the holders of the Class C Certificates.
Payments in respect of such Floating Rate Certificate Carryovers from proceeds
of a Cap Contract shall be paid to the related Classes of Offered Certificates,
pro rata based upon such Floating Rate Certificate Carryovers for each such
class of Offered Certificates.

            (i) The Trustee shall establish and maintain, for the benefit of the
      Trust Fund and the Certificateholders, the Cap Contract Account. On or
      prior to the related Cap Contract Termination Date, amounts, if any,
      received by the Trustee for the benefit of the Trust Fund in respect of
      the related Cap Contract shall be deposited by the Trustee into the Cap
      Contract Account and will be used to pay Floating Rate Certificate
      Carryovers on the related Offered Certificates. With respect to any
      Distribution Date on or prior to the related Cap Contract Termination
      Date, the amount, if any, payable by the Cap Contract Counterparty under
      the related Cap Contract will equal the product of (i) the excess of (x)
      One-Month LIBOR (as determined by the Cap Contract Counterparty and
      subject to a cap equal to the rate with respect to such Distribution Date
      as shown under the heading "1ML Upper Collar" in the schedule to the
      related Cap Contract), over (y) the rate with respect to such Distribution
      Date as shown under the heading "1ML Lower Collar" in the schedule to the
      related Cap Contract, (ii) an amount equal to the related Cap Contract
      Notional Balance and (iii) the number of days in such Accrual Period,
      divided by 360. If a payment is made to the Trust Fund under a Cap
      Contract and the Trustee is required to distribute excess amounts to the
      holders of the Class C Certificates as described above, the Trustee shall
      send a notice on the Business Day prior to the related Distribution Date,
      stating the amount received on the related Cap Contract, the amounts paid
      with respect to Floating Rate Certificate Carryovers and the amount due to
      the holders of the Class C Certificates. Such notice shall be sent by the
      Trustee via facsimile to the holders of the Class C Certificates.

            (ii) Amounts on deposit in the Cap Contract Account will remain
      uninvested pending distribution to Certificateholders.

            (iii) Each Cap Contract is scheduled to remain in effect until the
      related Cap Contract Termination Date and will be subject to early
      termination only in limited circumstances. Such circumstances include
      certain insolvency or bankruptcy events in relation to the Cap Contract
      Counterparty (after a grace period of three Local Business Days, as
      defined in the related Cap Contract, after notice of such failure is
      received by the Cap Contract Counterparty) to make a payment due under the
      related Cap Contract, the failure by the Cap Contract Counterparty (after
      a cure period of 20 days after notice of such failure is received) to
      perform any other agreement made by it under the related Cap Contract, the
      termination of the Trust Fund and the related Cap Contract becoming
      illegal or subject to certain kinds of taxation.

      (k) In accordance with this Agreement, the Servicer shall prepare and
deliver a report (the "Remittance Report") to the Trustee and the NIM Insurer in
the form of a computer readable magnetic tape (or by such other means as the
Servicer, the Trustee and the NIM Insurer may agree from time to time)
containing such data and information such as to permit the Trustee to prepare
the Monthly Statement to Certificateholders and make the required distributions
for the related Distribution Date.

      (l) The Trustee shall promptly notify the NIM Insurer of any proceeding or
the institution of any action, of which a Responsible Officer of the Trustee has
actual knowledge, seeking the avoidance as a preferential transfer under
applicable bankruptcy, insolvency, receivership or similar law (a "Preference

                                       84
<PAGE>

Claim") of any distribution made with respect to the Class C Certificates or the
Class P Certificates. Each Holder of the Class C Certificates or the Class P
Certificates, by its purchase of such Certificates and the Trustee hereby agree
that the NIM Insurer may at any time during the continuation of any proceeding
relating to a Preference Claim direct all matters relating to such Preference
Claim, including, without limitation, (i) the direction of any appeal of any
order relating to such Preference Claim and (ii) the posting of any surety,
supersedes or performance bond pending any such appeal. In addition and without
limitation of the foregoing, the NIM Insurer shall be subrogated to the rights
of the Trustee and each Holder of the Class C Certificates and the Class P
Certificates in the conduct of any such Preference Claim, including, without
limitation, all rights of any party to an adversary proceeding action with
respect to any court order issued in connection with any such Preference Claim;
provided, however, that the NIM Insurer will not have any rights with respect to
any Preference Claim set forth in this paragraph unless the indenture trustee
with respect to the NIM Notes or the holder of any NIM Notes has been required
to relinquish a distribution made on the Class C Certificates, the Class P
Certificates or the NIM Notes, as applicable, and the NIM Insurer made a payment
in respect of such relinquished amount.

(1)   The Class C Certificates shall not have a minimum dollar denominations as
      the Certificate Principal Balance thereof shall vary over time as
      described herein. The initial Overcollateralization Amount is $2,280.24.

(2)   The Class P Certificates shall not have minimum dollar denominations or
      Certificate Principal Balance and shall be issued in a minimum percentage
      interest of 25%.

      The Certificates shall be executed by manual or facsimile signature on
behalf of the Trustee by an authorized officer. Certificates bearing the manual
or facsimile signatures of individuals who were, at the time when such
signatures were affixed, authorized to sign on behalf of the Trustee shall bind
the Trust Fund, notwithstanding that such individuals or any of them have ceased
to be so authorized prior to the authentication and delivery of such
Certificates or did not hold such offices at the date of such authentication and
delivery. No Certificate shall be entitled to any benefit under this Agreement,
or be valid for any purpose, unless there appears on such Certificate a
certificate of authentication substantially in the form set forth as attached
hereto executed by the Trustee by manual signature, and such certificate

                                       88
<PAGE>

of authentication upon any Certificate shall be conclusive evidence, and the
only evidence, that such Certificate has been duly authenticated and delivered
hereunder. All Certificates shall be dated the date of their authentication. On
the Closing Date, the Trustee shall authenticate the Certificates to be issued
at the written direction of the Depositor, or any Affiliate thereof.

      SECTION 5.02. Certificate Register; Registration of Transfer and Exchange
of Certificates.

      (a) The Trustee shall maintain, or cause to be maintained in accordance
with the provisions of Section 5.09 hereof, a Certificate Register for the Trust
Fund in which, subject to the provisions of subsections (b) and (c) below and to
such reasonable regulations as it may prescribe, the Trustee shall provide for
the registration of Certificates and of Transfers and exchanges of Certificates
as herein provided. Upon surrender for registration of Transfer of any
Certificate, the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Certificates of the same
Class and of like aggregate Percentage Interest.

      At the option of a Certificateholder, Certificates may be exchanged for
other Certificates of the same Class in authorized denominations and evidencing
the same aggregate Percentage Interest upon surrender of the Certificates to be
exchanged at the office or agency of a Trustee. Whenever any Certificates are so
surrendered for exchange, the Trustee shall execute and the Trustee shall
authenticate and deliver the Certificates that the Certificateholder making the
exchange is entitled to receive. Every Certificate presented or surrendered for
registration of Transfer or exchange shall be accompanied by a written
instrument of Transfer in form satisfactory to a Trustee duly executed by the
holder thereof or his attorney duly authorized in writing.

      No service charge to the Certificateholders shall be made for any
registration of Transfer or exchange of Certificates, but payment of a sum
sufficient to cover any tax or governmental charge that may be imposed in
connection with any Transfer or exchange of Certificates may be required. All
Certificates surrendered for registration of Transfer or exchange shall be
canceled and subsequently destroyed by a Trustee in accordance with such
Trustee's customary procedures.

      (b) No Transfer of a Class C or Class P Certificate shall be made unless
such Transfer is made pursuant to an effective registration statement under the
Securities Act and any applicable state securities laws or is exempt from the
registration requirements under the Securities Act and such state securities
laws. In the event that a Transfer is to be made in reliance upon an exemption
from the Securities Act and such laws, in order to assure compliance with the
Securities Act and such laws, the Certificateholder desiring to effect such
Transfer and such Certificateholder's prospective transferee shall (except with
respect to the initial transfer of a Class C or Class P Certificate by Merrill
Lynch & Co. or, in connection with the transfer of a Class C or Class P
Certificate to the indenture trustee under an Indenture pursuant to which NIM
Notes are issued, whether or not such notes are guaranteed by the NIM Insurer)
each certify to each Trustee in writing the facts surrounding the Transfer in
substantially the forms set forth in Exhibit F (the "Transferor Certificate")
and (i) deliver a letter in substantially the form of either Exhibit G (the
"Investment Letter") or Exhibit H (the "Rule 144A Letter") or (ii) there shall
be delivered to each Trustee an Opinion of Counsel addressed to the Trustee that
such Transfer may be made pursuant to an exemption from the Securities Act,
which Opinion of Counsel shall not be an expense of the Depositor or the
Trustee. The Depositor shall provide to any Holder of a Class C or Class P
Certificate and any prospective transferee designated by any such Holder,
information regarding the related Certificates and the Mortgage Loans and such
other information as shall be necessary to satisfy the condition to eligibility
set forth in Rule 144A(d)(4) for Transfer of any such Certificate without
registration thereof under the Securities Act pursuant to the registration
exemption provided by Rule 144A. The Trustee shall cooperate with the Depositor
in providing the Rule 144A information referenced in the preceding sentence,
including providing to the Depositor such information in the possession of the

                                       89
<PAGE>

Trustee regarding the Certificates, the Mortgage Loans and other matters
regarding the Trust Fund as the Depositor shall reasonably request to meet its
obligation under the preceding sentence. Each Holder of a Class C or Class P
Certificate desiring to effect such Transfer shall, and does hereby agree to,
indemnify the Depositor and the Trustee against any liability that may result if
the Transfer is not so exempt or is not made in accordance with such federal and
state laws.

      No transfer of an ERISA Restricted Certificate that is a Class R
Certificate may be made to any Person that is an employee benefit plan subject
to Title I of ERISA, a plan subject to Section 4975 of the Code or a plan
subject to any state, local, federal, non-U.S. or other law substantively
similar to the foregoing provisions of ERISA or the Code ("Similar Law"), or to
any Person directly or indirectly acting on behalf of or using any assets of any
such plan (collectively, "Plan"). Each Person to whom a Class R Certificate is
to be transferred shall be required or deemed to represent that it is not a
Plan.

      No transfer of an ERISA-Restricted Certificate that is a Class C or Class
P Certificate shall be made to any Person unless the Trustee has received (A) a
representation that either (I) such transferee is not a Plan, or (II) if the
Certificate has been the subject of an ERISA-Qualifying Underwriting, a
representation that such transferee is an insurance company that is acquiring
the Certificate with assets of an "insurance company general account," as
defined in Section V(e) of Prohibited Transaction Class Exemption ("PTCE")
95-60, and the acquisition and holding of the Certificate are covered and exempt
under Sections I and III of PTCE 95-60, or (B) solely in the case of any such
Certificate that is a Definitive Certificate, an Opinion of Counsel satisfactory
to the Trustee, and upon which the Trustee and the NIM Insurer shall be entitled
to rely, to the effect that the acquisition and holding of such Certificate will
not constitute or result in a nonexempt prohibited transaction under ERISA or
the Code, or a violation of Similar Law, and will not subject the Trustee or the
NIM Insurer to any obligation in addition to those expressly undertaken in this
Agreement, which Opinion of Counsel shall not be an expense of the Trustee or
the NIM Insurer.

      For purposes of the two immediately preceding paragraphs of this
Subsection 5.02(b), other than clause (B) in the immediately preceding
paragraph, the representations as set forth therein shall be deemed to have been
made to the Trustee by the transferee's acceptance of an ERISA Restricted
Certificate (or the acceptance by a Certificate Owner of the beneficial interest
in any Class of ERISA Restricted Certificates). Notwithstanding any other
provision herein to the contrary, any purported transfer of an ERISA Restricted
Certificate to or on behalf of a Plan without the delivery to the Trustee of a
representation or an Opinion of Counsel satisfactory to the Trustee as described
above shall be void and of no effect. Neither the Trustee nor the NIM Insurer
shall be under any liability to any Person for any registration of transfer of
any ERISA Restricted Certificate that is in fact not permitted by this Section
5.02(b) nor shall the Trustee be under any liability for making any payments due
on such Certificate to the Holder thereof or taking any other action with
respect to such Holder under the provisions of this Agreement so long as the
transfer was registered by the Trustee in accordance with the foregoing
requirements. The Trustee and the NIM Insurer shall be entitled, but not
obligated, to recover from any Holder of any ERISA Restricted Certificate that
was in fact a Plan and that held such Certificate in violation of this Section
5.02(b) all payments made on such ERISA Restricted Certificate at and after the
time it commenced such holding. Any such payments so recovered shall be paid and
delivered to the last preceding Holder of such Certificate that is not a Plan.

      No Transfer of a Class C Certificate may be made to a person that is
either (i) not a "United States person" (as defined for purposes of Section 7701
of the Code) or (ii) a Disqualified Organization or a Person acquiring such
Certificate on behalf (as a broker, agent, nominee or otherwise) of a
Disqualified Organization. The Trustee shall not register any Transfer of a
Class C Certificate unless the Trustee shall have been furnished with a
Transferee Letter or a letter from the initial Holder of the Class C
Certificates in the form attached as Exhibit M. Any Transfer of a Class C
Certificate in violation of the provisions of

                                       90
<PAGE>

this Section 5.02(b) shall be absolutely null and void and the purported
Transferee shall acquire absolutely no rights in such Class C Certificate.

      (c) Each Person who has or who acquires any Ownership Interest in a Class
R Certificate shall be deemed by the acceptance or acquisition of such Ownership
Interest to have agreed to be bound by the following provisions, and the rights
of each Person acquiring any Ownership Interest in a Class R Certificate are
expressly subject to the following provisions:

            (i) Each Person holding or acquiring any Ownership Interest in a
      Class R Certificate shall be a Permitted Transferee and shall promptly
      notify the Trustee of any change or impending change in its status as a
      Permitted Transferee.

            (ii) No Ownership Interest in a Class R Certificate may be
      purchased, transferred or sold, directly or indirectly, except in
      accordance with the provisions hereof. No Ownership Interest in a Class R
      Certificate may be registered on the Closing Date or thereafter
      transferred, and the Trustee shall not register the Transfer of any Class
      R Certificate unless, in addition to the certificates required to be
      delivered to the Trustee under subparagraph (b) above, the Trustee shall
      have been furnished with an affidavit (a "Transfer Affidavit") of the
      initial owner or the proposed transferee in the form attached hereto as
      Exhibit E-1 and an affidavit of the proposed transferor in the form
      attached hereto as Exhibit E-2. In the absence of a contrary instruction
      from the transferor of a Class R Certificate, declaration (11) in Appendix
      A of the Transfer Affidavit may be left blank. If the transferor requests
      by written notice to the Trustee prior to the date of the proposed
      transfer that one of the two other forms of declaration (11) in Appendix A
      of the Transfer Affidavit be used, then the requirements of this Section
      5.02(c)(ii) shall not have been satisfied unless the Transfer Affidavit
      includes such other form of declaration.

            (iii) Each Person holding or acquiring any Ownership Interest in a
      Class R Certificate shall agree (A) to obtain a Transfer Affidavit from
      any other Person to whom such Person attempts to Transfer its Ownership
      Interest in a Class R Certificate, (B) to obtain a Transfer Affidavit from
      any Person for whom such Person is acting as nominee, trustee or agent in
      connection with any Transfer of a Class R Certificate and (C) not to
      Transfer its Ownership Interest in a Class R Certificate or to cause the
      Transfer of an Ownership Interest in a Class R Certificate to any other
      Person if it has actual knowledge that such Person is not a Permitted
      Transferee. Further, no transfer, sale or other disposition of any
      Ownership Interest in a Class R Certificate may be made to a person who is
      not a U.S. Person (within the meaning of section 7701 of the Code) unless
      such person furnishes the transferor and the Trustee with a duly completed
      and effective Internal Revenue Service Form W-8ECI (or any successor
      thereto) and the Trustee consents to such transfer, sale or other
      disposition in writing.

            (iv) Any attempted or purported Transfer of any Ownership Interest
      in a Class R Certificate in violation of the provisions of this Section
      5.02(c) shall be absolutely null and void and shall vest no rights in the
      purported Transferee. If any purported transferee shall become a Holder of
      a Class R Certificate in violation of the provisions of this Section
      5.02(c), then the last preceding Permitted Transferee shall be restored to
      all rights as Holder thereof retroactive to the date of registration of
      Transfer of such Class R Certificate. The Trustee shall be under no
      liability to any Person for any registration of Transfer of a Class R
      Certificate that is in fact not permitted by Section 5.02(b) and this
      Section 5.02(c) or for making any payments due on such Certificate to the
      Holder thereof or taking any other action with respect to such Holder
      under the provisions of this Agreement so long as the Transfer was
      registered after receipt of the related Transfer Affidavit. The Trustee
      shall be entitled but not obligated to recover from any Holder of a Class
      R Certificate that was in fact not a Permitted Transferee at the time it
      became a Holder or, at such

                                       91
<PAGE>

      subsequent time as it became other than a Permitted Transferee, all
      payments made on such Class R Certificate at and after either such time.
      Any such payments so recovered by the Trustee shall be paid and delivered
      by the Trustee to the last preceding Permitted Transferee of such
      Certificate.

            (v) At the option of the Holder of the Class R Certificate, the
      Class LTR Interest, and the Residual Interest may be severed and
      represented by separate certificates; provided, however, that such
      separate certification may not occur until the NIM Insurer and the Trustee
      receive an Opinion of Counsel addressed to the Trustee to the effect that
      separate certification in the form and manner proposed would not result in
      the imposition of federal tax upon the Trust Fund or any of the REMICs
      provided for herein or cause any of the REMICs provided for herein to fail
      to qualify as a REMIC; and provided further, that the provisions of
      Sections 5.02(b) and (c) will apply to each such separate certificate as
      if the separate certificate were a Class R Certificate. If, as evidenced
      by an Opinion of Counsel, it is necessary to preserve the REMIC status of
      any of the REMICs provided for herein, the Class LTR Interest, and the
      Residual Interest shall be severed and represented by separate
      Certificates.

      The restrictions on Transfers of a Class R Certificate set forth in this
Section 5.02(c) shall cease to apply (and the applicable portions of the legend
on a Class R Certificate may be deleted) with respect to Transfers occurring
after delivery to the Trustee and the NIM Insurer of an Opinion of Counsel
addressed to the Trustee, which Opinion of Counsel shall not be an expense of
the Trustee or the Depositor, to the effect that the elimination of such
restrictions will not cause any of the REMICs provided for herein to fail to
qualify as a REMIC at any time that the Certificates are outstanding or result
in the imposition of any tax on the Trust Fund, any REMIC provided for herein, a
Certificateholder or another Person. Each Person holding or acquiring any
Ownership Interest in a Class R Certificate hereby consents to any amendment of
this Agreement that, based on an Opinion of Counsel addressed to and furnished
to the Trustee, is reasonably necessary (a) to ensure that the record ownership
of, or any beneficial interest in, a Class R Certificate is not transferred,
directly or indirectly, to a Person that is not a Permitted Transferee and (b)
to provide for a means to compel the Transfer of a Class R Certificate that is
held by a Person that is not a Permitted Transferee to a Holder that is a
Permitted Transferee.

      (d) The transferor of the Class R Certificate shall notify the Trustee in
writing upon the transfer of the Class R Certificate.

      (e) The preparation and delivery of all certificates, opinions and other
writings referred to above in this Section 5.02 shall not be an expense of the
Trust Fund, the Depositor or the Trustee.

      SECTION 5.03. Mutilated, Destroyed, Lost or Stolen Certificates.

      If (a) any mutilated Certificate is surrendered to the Trustee or the
Trustee receives evidence to its satisfaction of the destruction, loss or theft
of any Certificate and of the ownership thereof and (b) there is delivered to
the Trustee and the NIM Insurer such security or indemnity as may be required by
them to save each of them harmless, then, in the absence of notice to the
Trustee that such Certificate has been acquired by a bona fide purchaser, the
Trustee shall execute, authenticate and deliver, in exchange for or in lieu of
any such mutilated, destroyed, lost or stolen Certificate, a new Certificate of
like Class, tenor and Percentage Interest. In connection with the issuance of
any new Certificate under this Section 5.03, the Trustee may require the payment
of a sum sufficient to cover any tax or other governmental charge that may be
imposed in relation thereto and any other expenses (including the fees and
expenses of the Trustee) connected therewith. Any replacement Certificate issued
pursuant to this Section 5.03 shall constitute complete and indefeasible
evidence of ownership in the Trust Fund, as if originally issued, whether or not
the lost, stolen or destroyed Certificate shall be found at any time. All
Certificates

                                       92
<PAGE>

surrendered to the Trustee under the terms of this Section 5.03 shall be
canceled and destroyed by the Trustee in accordance with its standard procedures
without liability on its part.

      SECTION 5.04. Persons Deemed Owners.

      The NIM Insurer, the Trustee and any agent of the NIM Insurer or the
Trustee may treat the Person in whose name any Certificate is registered as the
owner of such Certificate for the purpose of receiving distributions as provided
in this Agreement and for all other purposes whatsoever, and neither the NIM
Insurer nor the Trustee, nor any agent of the NIM Insurer or the Trustee shall
be affected by any notice to the contrary.

      SECTION 5.05. Access to List of Certificateholders' Names and Addresses.

      If three or more Certificateholders (a) request such information in
writing from the Trustee, (b) state that such Certificateholders desire to
communicate with other Certificateholders with respect to their rights under
this Agreement or under the Certificates, and (c) provide a copy of the
communication that such Certificateholders propose to transmit or if the NIM
Insurer or the Depositor shall request such information in writing from the
Trustee, then the Trustee shall, within ten Business Days after the receipt of
such request, provide the NIM Insurer, the Depositor or such Certificateholders
at such recipients' expense the most recent list of the Certificateholders of
the Trust Fund held by the Trustee, if any. The Depositor and every
Certificateholder, by receiving and holding a Certificate, agree that the
Trustee shall not be held accountable by reason of the disclosure of any such
information as to the list of the Certificateholders hereunder, regardless of
the source from which such information was derived.

      SECTION 5.06. Book-Entry Certificates.

      The Regular Certificates, upon original issuance, shall be issued in the
form of one or more typewritten Certificates representing the Book-Entry
Certificates, to be delivered to the Depository by or on behalf of the
Depositor. The Book-Entry Certificates shall initially be registered on the
Certificate Register in the name of the Depository or its nominee, and no
Certificate Owner of a Book-Entry Certificate will receive a definitive
certificate representing such Certificate Owner's interest in such Certificates,
except as provided in Section 5.08. Unless and until definitive, fully
registered Certificates ("Definitive Certificates") have been issued to the
Certificate Owners of the Book-Entry Certificates pursuant to Section 5.08:

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

      (b) the Depositor, the Trustee and the NIM Insurer may deal with the
Depository and the Depository Participants for all purposes (including the
making of distributions) as the authorized representative of the respective
Certificate Owners of the Book-Entry Certificates;

      (c) registration of the Book-Entry Certificates may not be transferred by
the Trustee except to another Depository;

      (d) the rights of the respective Certificate Owners of the Book-Entry
Certificates shall be exercised only through the Depository and the Depository
Participants and shall be limited to those established by law and agreements
between the Owners of the Book-Entry Certificates and the Depository and/or the
Depository Participants. Pursuant to the Depository Agreement, unless and until
Definitive Certificates are issued pursuant to Section 5.08, the Depository will
make book-entry transfers among the Depository Participants and receive and
transmit distributions of principal and interest on the related Certificates to
such Depository Participants;

                                       93
<PAGE>

      (e) the Depository may collect its usual and customary fees, charges and
expenses from its Depository Participants;

      (f) the Trustee may rely and shall be fully protected in relying upon
information furnished by the Depository with respect to its Depository
Participants; and

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

      For purposes of any provision of this Agreement requiring or permitting
actions with the consent of, or at the direction of, Certificateholders
evidencing a specified percentage of the aggregate unpaid principal amount of
any Class of Certificates, such direction or consent may be given by Certificate
Owners (acting through the Depository and the Depository Participants) owning
Book-Entry Certificates evidencing the requisite percentage of principal amount
of such Class of Certificates.

      SECTION 5.07. Notices to Depository.

      Whenever any notice or other communication is required to be given to
Certificateholders of the Class with respect to which Book-Entry Certificates
have been issued, unless and until Definitive Certificates shall have been
issued to the related Certificate Owners and the Trustee shall give all such
notices and communications to the Depository.

      SECTION 5.08. Definitive Certificates.

      If, after Book-Entry Certificates have been issued with respect to any
Certificates, (a) the Depository or the Depositor advises the Trustee that the
Depository is no longer willing, qualified or able to discharge properly its
responsibilities under the Depository Agreement with respect to such
Certificates and the Depositor is unable to locate a qualified successor, (b)
the Depositor, at its sole option, advises the Trustee that it elects to
terminate the book-entry system with respect to such Certificates through the
Depository or (c) after the occurrence and continuation of an Event of Default,
Certificate Owners of such Book-Entry Certificates having not less than 51% of
the Voting Rights evidenced by any Class of Book-Entry Certificates advise the
Trustee and the Depository in writing through the Depository Participants that
the continuation of a book-entry system with respect to Certificates of such
Class through the Depository (or its successor) is no longer in the best
interests of the Certificate Owners of such Class, then the Trustee shall notify
all Certificate Owners of such Book-Entry Certificates and the NIM Insurer,
through the Depository, of the occurrence of any such event and of the
availability of Definitive Certificates to Certificate Owners of such Class
requesting the same. The Depositor shall provide the Trustee with an adequate
inventory of certificates to facilitate the issuance and transfer of Definitive
Certificates. Upon surrender to the Trustee of any such Certificates by the
Depository, accompanied by registration instructions from the Depository for
registration, the Trustee shall authenticate and deliver such Definitive
Certificates. Neither the Depositor nor the Trustee shall be liable for any
delay in delivery of such instructions and each may conclusively rely on, and
shall be protected in relying on, such instructions. Upon the issuance of such
Definitive Certificates, all references herein to obligations imposed upon or to
be performed by the Depository shall be deemed to be imposed upon and performed
by the Trustee, to the extent applicable with respect to such Definitive
Certificates and the Trustee shall recognize the Holders of such Definitive
Certificates as Certificateholders hereunder.

      SECTION 5.09. Maintenance of Office or Agency.

      The Trustee will maintain or cause to be maintained at its expense an
office or offices or agency or agencies where Certificates may be surrendered
for registration of transfer or exchange. The Trustee

                                       94
<PAGE>

initially designates its office at 2001 Bryan Street, 8th Floor, Dallas, Texas
75201, Attention: Institutional Trust Services/Transfer Department as offices
for such purposes. The Trustee will give prompt written notice to the
Certificateholders of any change in such location of any such office or agency.

                                   ARTICLE VI
                         THE DEPOSITOR AND THE SERVICER

      SECTION 6.01. Respective Liabilities of the Depositor and the Servicer.

      The Depositor and the Servicer shall each be liable in accordance herewith
only to the extent of the obligations specifically and respectively imposed upon
and undertaken by them herein.

      SECTION 6.02. Merger or Consolidation of the Depositor or the Servicer.

      Except as provided in the next paragraph, the Depositor and the Servicer
will each keep in full effect its existence, rights and franchises as a
corporation or banking association under the laws of the United States or under
the laws of one of the States thereof and will each obtain and preserve its
qualification to do business as a foreign corporation in each jurisdiction in
which such qualification is or shall be necessary to protect the validity and
enforceability of this Agreement, or any of the Mortgage Loans and to perform
its respective duties under this Agreement.

      Any Person into which the Depositor or Servicer may be merged or
consolidated, or any Person resulting from any merger or consolidation to which
the Depositor or Servicer shall be a party, or any Person succeeding to the
business of the Depositor or Servicer, shall be the successor of the Depositor
or Servicer, as the case may be, hereunder, without the execution or filing of
any paper or any further act on the part of any of the parties hereto, anything
herein to the contrary notwithstanding (except for the execution of an
assumption agreement where such succession is not effected by operation of law);
provided, however, that the successor or surviving Person to a Servicer shall be
qualified to sell mortgage loans to, and to service mortgage loans on behalf of,
Fannie Mae or Freddie Mac.

      SECTION 6.03. Limitation on Liability of the Depositor, the Servicer and
Others.

      None of the Depositor, the Servicer nor any of the directors, officers,
employees or agents of the Depositor or the Servicer shall be under any
liability to the Trust Fund or the Certificateholders for any action taken or
for refraining from the taking of any action in good faith pursuant to this
Agreement, or for errors in judgment; provided, however, that this provision
shall not protect the Depositor, the Servicer or any such Person against any
breach of representations or warranties made by it herein or protect the
Depositor, the Servicer or any such Person from any liability that would
otherwise be imposed by reasons of willful misfeasance, bad faith or negligence
in the performance of duties or by reason of reckless disregard of obligations
and duties hereunder. The Depositor, the Servicer and any director, officer,
employee or agent of the Depositor or the Servicer may rely in good faith on any
document of any kind prima facie properly executed and submitted by any Person
respecting any matters arising hereunder. The Depositor, the Servicer and any
director, officer, employee or agent of the Depositor or the Servicer shall be
indemnified by the Trust Fund and held harmless against any loss, liability or
expense, incurred in connection with the performance of their duties under this
agreement or incurred in connection with any audit, controversy or judicial
proceeding relating to a governmental taxing authority or any legal action
relating to this Agreement or the Certificates, other than any loss, liability
or expense incurred by reason of willful misfeasance, bad faith or negligence in
the performance of duties hereunder or by reason of reckless disregard of
obligations and duties hereunder. None of the Depositor nor the Servicer shall
be under any obligation to appear in, prosecute or defend any legal action that
is not incidental to its

                                       95
<PAGE>

respective duties hereunder and that in its opinion may involve it in any
expense or liability; provided, however, that any of the Depositor or the
Servicer may, in its discretion undertake any such action that it may deem
necessary or desirable in respect of this Agreement and the rights and duties of
the parties hereto and interests of the Servicer and the Certificateholders
hereunder. In such event, the legal expenses and costs of such action and any
liability resulting therefrom shall be, expenses, costs and liabilities of the
Trust Fund, and the Depositor and the Servicer shall be entitled to be
reimbursed therefor out of the Collection Account as provided by Section 3.08
hereof.

      SECTION 6.04. Limitation on Resignation of Servicer.

      The Servicer shall not resign from the obligations and duties hereby
imposed on it except upon determination that its duties hereunder are no longer
permissible under applicable law. Any such determination permitting the
resignation of the Servicer shall be evidenced by an Opinion of Counsel to such
effect delivered to the Trustee and the NIM Insurer. No such resignation shall
become effective until the Trustee or a successor servicer reasonably acceptable
to the Trustee and the NIM Insurer is appointed and has assumed the Servicer's
responsibilities, duties, liabilities and obligations hereunder. Any such
resignation shall not relieve the Servicer of any of the obligations specified
in Sections 7.01, 7.02 and 7.03 as obligations that survive the resignation or
termination of the Servicer.

      The Trustee, the Depositor and the NIM Insurer hereby specifically (i)
consent to the pledge and assignment by the Servicer of all the Servicer's
right, title and interest in, to and under this Agreement to the Servicing
Rights Pledgee, for the benefit of certain lenders, and (ii) provided that no
Event of Default exists, agree that upon delivery to the Trustee by the
Servicing Rights Pledgee of a letter signed by the Servicer whereby the Servicer
shall resign as Servicer under this Agreement, the Trustee shall appoint the
Servicing Rights Pledgee or its designee as successor servicer but only if such
successor servicer meets the requirements of a successor servicer under this
Agreement and agrees to be subject to the terms of this Agreement. If, pursuant
to any provision hereof, the duties of the Servicer are transferred to a
successor servicer, the entire amount of the Servicing Fee and other
compensation payable to the Servicer pursuant hereto shall thereafter be payable
to such successor servicer.

      SECTION 6.05. Errors and Omissions Insurance; Fidelity Bonds.

      The Servicer shall, for so long as it acts as servicer under this
Agreement, obtain and maintain in force (a) a policy or policies of insurance
covering errors and omissions in the performance of its obligations as servicer
hereunder, and (b) a fidelity bond in respect of its officers, employees and
agents. Each such policy and bond shall, together, meet the requirements of
Fannie Mae or Freddie Mac, unless the Servicer has obtained a waiver of such
requirements from the Seller. The Servicer shall provide the Trustee and the NIM
Insurer, upon request with reasonable notice, with copies of such policies and
fidelity bond or a certification from the insurance provider evidencing such
policies and fidelity bond. The Servicer may be deemed to have complied with
this provision if an Affiliate of the Servicer has such errors and omissions and
fidelity bond coverage and, by the terms of such insurance policy or fidelity
bond, the coverage afforded thereunder extends to the Servicer. In the event
that any such policy or bond ceases to be in effect, the Servicer shall use its
reasonable best efforts to obtain a comparable replacement policy or bond from
an insurer or issuer meeting the requirements set forth above as of the date of
such replacement. The Servicer shall ensure that any such policy or fidelity
bond shall by its terms not be cancelable without thirty days' prior written
notice to the Trustee and the NIM Insurer.

                        DEFAULT; TERMINATION OF SERVICER

      SECTION 7.01. Events of Default.

      "Event of Default," wherever used herein, means any one of the following
events:

            (i) any failure by the Servicer to make any Advance to deposit in
      the Collection Account or the Certificate Account or remit to the Trustee
      any payment (excluding a payment required to be made under Section 4.01
      hereof) required to be made under the terms of this Agreement, which
      failure shall continue unremedied for three Business Days and, with
      respect to a payment required to be made under Section 4.01 hereof, for
      one Business Day, after the date on which written notice of such failure
      shall have been given to the Servicer by the Trustee or the Depositor, or
      to the Trustee and the Servicer by the NIM Insurer or the Holders of
      Certificates evidencing not less than 50% of the Voting Rights evidenced
      by the Certificates; or

            (ii) any failure by the Servicer to observe or perform in any
      material respect any other of the covenants or agreements on the part of
      the Servicer contained in this Agreement or any representation or warranty
      shall prove to be untrue, which failure or breach shall continue
      unremedied for a period of 60 days after the date on which written notice
      of such failure shall have been given to the Servicer by the Trustee or
      the Depositor, or to the Trustee by the NIM Insurer or the Holders of
      Certificates evidencing not less than 50% of the Voting Rights evidenced
      by the Certificates; or

            (iii) a decree or order of a court or agency or supervisory
      authority having jurisdiction for the appointment of a receiver or
      liquidator in any insolvency, readjustment of debt, marshaling of assets
      and liabilities or similar proceedings, or for the winding-up or
      liquidation of its affairs, shall have been entered against the Servicer
      and such decree or order shall have remained in force undischarged or
      unstayed for a period of 60 consecutive days; or

            (iv) consent by the Servicer to the appointment of a receiver or
      liquidator in any insolvency, readjustment of debt, marshaling of assets
      and liabilities or similar proceedings of or relating to the Servicer or
      all or substantially all of the property of the Servicer; or

            (v) admission by a Servicer in writing of its inability to pay its
      debts generally as they become due, file a petition to take advantage of,
      or commence a voluntary case under, any applicable insolvency or
      reorganization statute, make an assignment for the benefit of its
      creditors, or voluntarily suspend payment of its obligations.

      If an Event of Default shall occur with respect to the Servicer, then, and
in each and every such case, so long as such Event of Default shall not have
been remedied within the applicable grace period, or solely with respect to
clause (i) above by 5:00 p.m. on the Servicer Remittance Date, the Trustee may
(with the written consent of the NIM Insurer, except after a NIM Insurer
Default), or at the direction of the NIM Insurer or the Holders of Certificates
evidencing not less than 50% of the Voting Rights evidenced by the Certificates
(with the written consent of the NIM Insurer, except after a NIM Insurer
Default), shall, by notice in writing to the Servicer (with a copy to each
Rating Agency), terminate all of the rights and obligations of the Servicer
under this Agreement and in and to the Mortgage Loans and the proceeds thereof,
other than its rights as a Certificateholder hereunder. On or after the receipt
by the Servicer of such written notice, all authority and power of the Servicer
hereunder, subject to and in accordance with Section 6.04 hereof, whether with
respect to the Mortgage Loans or otherwise, shall pass to and be vested in the
Trustee as successor servicer. To the extent the Event of Default resulted from
the

                                       97
<PAGE>

failure of the Servicer to make a required Advance, the Trustee, in its capacity
as successor servicer, shall thereupon make any Advance described in Section
4.01 hereof subject to Section 3.04 hereof. The Trustee is hereby authorized and
empowered to execute and deliver, on behalf of the Servicer, as attorney-in-fact
or otherwise, any and all documents and other instruments, and to do or
accomplish all other acts or things necessary or appropriate to effect the
purposes of such notice of termination, whether to complete the transfer and
endorsement or assignment of the Mortgage Loans and related documents, or
otherwise. Unless expressly provided in such written notice, no such termination
shall affect any obligation of the Servicer to pay amounts owed pursuant to
Article VIII. The Servicer agrees to cooperate with the Trustee in effecting the
termination of the Servicer's responsibilities and rights hereunder, including,
without limitation, the transfer to the Trustee of all cash amounts which shall
at the time be credited to the Collection Account, or thereafter be received
with respect to the Mortgage Loans. The Servicer and the Trustee shall promptly
notify the Rating Agencies of the occurrence of an Event of Default or an event
that, with notice, passage of time, other action or any combination of the
foregoing would be an Event of Default, such notice to be provided in any event
within two Business Days of such occurrence.

      Notwithstanding any termination of the activities of the Servicer
hereunder, the Servicer shall be entitled to receive, out of any late collection
of a Scheduled Payment on a Mortgage Loan that was due prior to the notice
terminating the Servicer's rights and obligations as Servicer hereunder and
received after such notice, that portion thereof to which the Servicer would
have been entitled pursuant to Sections 3.08(a)(i) through (viii), and any other
amounts payable to the Servicer hereunder the entitlement to which arose prior
to the termination of its activities hereunder. Notwithstanding anything herein
to the contrary, upon termination of the Servicer hereunder, any liabilities of
the Servicer which accrued prior to such termination shall survive such
termination.

      SECTION 7.02. Servicer Trigger Event

      A "Servicer Trigger Event," shall be deemed to have occurred on any
Distribution Date where the aggregate amount of cumulative Realized Losses
incurred since the Cut-off Date through the last day of the related Accrual
Period divided by the Pool Balance as of the Cut-off Date exceeds the applicable
percentages set forth below with respect to such Distribution Date:

<TABLE>
<CAPTION>
DISTRIBUTION DATE OCCURRING IN                      PERCENTAGE
------------------------------                      ----------
<S>                                                 <C>
November 2007 through October 2008                    4.25%
November 2008 through October 2009                    5.60%
November 2009 through October 2010                    7.50%
November 2010 and thereafter                          8.00%
</TABLE>

      Upon discovery by the Trustee that a Servicer Trigger Event has occurred,
the Trustee shall promptly (and in any event within 5 Business Days of
discovery) give written notice thereof to the Certificateholders. If a Servicer
Trigger Event shall occur, then the Holders of Certificates evidencing not less
than 51% of the Voting Rights evidenced by the Certificates (with the written
consent of the NIM Insurer, except after a NIM Insurer Default), may, by notice
in writing to the Servicer (with a copy to each Rating Agency), terminate all of
the rights and obligations of the Servicer under this Agreement and in and to
the Mortgage Loans and the proceeds thereof, other than its rights as a
Certificateholder hereunder. On or after the receipt by the Servicer of such
written notice, all authority and power of the Servicer hereunder, subject to
and in accordance with Section 6.04 hereof, whether with respect to the Mortgage
Loans or otherwise, shall pass to and be vested in the Trustee as successor
servicer. The Trustee is hereby authorized and empowered as successor servicer
to execute and deliver, on behalf of the Servicer, as attorney-in-fact or
otherwise, any and all documents and other instruments, and to do or

                                       98
<PAGE>

accomplish all other acts or things necessary or appropriate to effect the
purposes of such notice of termination, whether to complete the transfer and
endorsement or assignment of the Mortgage Loans and related documents, or
otherwise. Unless expressly provided in such written notice, no such termination
shall affect any obligation of the Servicer to pay amounts owed pursuant to
Article VIII. The Servicer agrees to cooperate with the Trustee as successor
servicer in effecting the termination of the Servicer's responsibilities and
rights hereunder, including, without limitation, the transfer to the Trustee as
successor servicer of all cash amounts which shall at the time be credited to
the Collection Account, or thereafter be received with respect to the Mortgage
Loans. The Servicer and the Trustee shall promptly notify the Rating Agencies of
the occurrence of a Servicer Trigger Event, such notice to be provided in any
event within two Business Days of such occurrence.

      Notwithstanding any termination of the activities of the Servicer
hereunder, the Servicer shall be entitled to receive, out of any late collection
of a Scheduled Payment on a Mortgage Loan that was due prior to the notice
terminating the Servicer's rights and obligations as Servicer hereunder and
received after such notice, that portion thereof to which the Servicer would
have been entitled pursuant to Sections 3.08(a)(i) through (viii), and any other
amounts payable to the Servicer hereunder the entitlement to which arose prior
to the termination of its activities hereunder. Notwithstanding anything herein
to the contrary, upon termination of the Servicer hereunder, any liabilities of
the Servicer which accrued prior to such termination shall survive such
termination.

      SECTION 7.03. Trustee to Act; Appointment of Successor.

      On and after the time the Servicer receives a notice of termination
pursuant to Section 7.01 or 7.02 hereof, the Trustee shall, to the extent
provided in Section 3.04, be the successor to the Servicer in its capacity as
servicer under this Agreement and the transactions set forth or provided for
herein and shall be subject to all the responsibilities, duties and liabilities
relating thereto placed on the Servicer by the terms and provisions hereof and
applicable law including the obligation to make advances pursuant to Section
4.01. As compensation therefor, subject to the last paragraph of Section 7.01 or
7.02, as applicable, the Trustee shall be entitled to all compensation and
reimbursement for costs and expenses that the Servicer would have been entitled
to hereunder if the Servicer had continued to act hereunder. Notwithstanding the
foregoing, if the Trustee has become the successor to the Servicer in accordance
with Section 7.01 or 7.02 hereof, the Trustee may, if it shall be unwilling to
so act, or shall, if it is prohibited by applicable law from making Advances
pursuant to Section 4.01 hereof or if it is otherwise unable to so act, appoint,
or petition a court of competent jurisdiction to appoint, any established
mortgage loan servicing institution the appointment of which successor shall be
approved by the NIM Insurer and which does not adversely affect the then current
rating of the Certificates by each Rating Agency as the successor to the
Servicer hereunder in the assumption of all or any part of the responsibilities,
duties or liabilities of the Servicer hereunder. Any successor servicer shall be
an institution that is acceptable to the NIM Insurer and is a Fannie Mae and
Freddie Mac approved seller/servicer in good standing, that has a net worth of
at least $15,000,000, and that is willing to service the Mortgage Loans and
executes and delivers to the Depositor and the Trustee an agreement accepting
such delegation and assignment, that contains an assumption by such Person of
the rights, powers, duties, responsibilities, obligations and liabilities of the
Servicer (other than liabilities of the Servicer under Section 6.03 hereof
incurred prior to termination of the Servicer under Section 7.01 or 7.02), with
like effect as if originally named as a party to this Agreement; and provided
further that each Rating Agency acknowledges that its rating of the Certificates
in effect immediately prior to such assignment and delegation will not be
qualified or reduced as a result of such assignment and delegation. No
appointment of a successor to the Servicer hereunder shall be effective until
the Trustee and the NIM Insurer shall have consented thereto, prior written
consent of the NIM Insurer is obtained and written notice of such proposed
appointment shall have been provided by the Trustee to each Certificateholder.
The Trustee shall not resign as servicer until a successor servicer has been
appointed and has accepted such appointment. Pending appointment of a successor
to the

                                       99
<PAGE>

Servicer hereunder, the Trustee, unless the Trustee is prohibited by law from so
acting, shall, subject to Section 3.04 hereof, act in such capacity as
hereinabove provided. In connection with such appointment and assumption, the
Trustee may make such arrangements for the compensation of such successor out of
payments on Mortgage Loans as it and such successor shall agree; provided,
however, that no such compensation shall be in excess of that permitted the
Servicer hereunder. The Trustee and such successor shall take such action,
consistent with this Agreement, as shall be necessary to effectuate any such
succession. Neither the Trustee nor any other successor servicer shall be deemed
to be in default hereunder by reason of any failure to make, or any delay in
making, any distribution hereunder or any portion thereof or any failure to
perform, or any delay in performing, any duties or responsibilities hereunder,
in either case caused by the failure of the Servicer to deliver or provide, or
any delay in delivering or providing, any cash, information, documents or
records to it.

      Any successor to the Servicer as servicer shall give notice to the
Mortgagors of such change of servicer and shall, during the term of its service
as servicer maintain in force the policy or policies that the Servicer is
required to maintain pursuant to Section 6.05.

      SECTION 7.04. Notification to Certificateholders.

      (a) Upon any termination of or appointment of a successor to the Servicer,
the Trustee shall give prompt written notice thereof to Certificateholders, the
NIM Insurer and to each Rating Agency.

      (b) Within 60 days after the occurrence of any Event of Default, the
Trustee shall transmit by mail to all Certificateholders and the NIM Insurer
notice of each such Event of Default hereunder known to the Trustee, unless such
Event of Default shall have been cured or waived.

                                  ARTICLE VIII
                             CONCERNING THE TRUSTEE

      SECTION 8.01. Duties of Trustee.

      The Trustee, prior to the occurrence of an Event of Default and after the
curing of all Events of Default that may have occurred, shall undertake to
perform such duties and only such duties as are specifically set forth in this
Agreement. In case an Event of Default has occurred and remains uncured, the
Trustee shall exercise such of the rights and powers vested in it by this
Agreement and use the same degree of care and skill in their exercise as a
prudent person would exercise or use under the circumstances in the conduct of
such person's own affairs. In case an Event of Default or other default by the
Servicer or the Depositor hereunder shall occur and be continuing, the Trustee,
shall, at the direction of the majority of the Certificateholders or the NIM
Insurer, or may, proceed to protect and enforce its rights and the rights of the
Certificateholders or the NIM Insurer under this Agreement by a suit, action or
proceeding in equity or at law or otherwise, whether for the specific
performance of any covenant or agreement contained in this agreement or in aid
of the execution of any power granted in this Agreement or for the enforcement
of any other legal, equitable or other remedy, as the Trustee, being advised by
counsel, and subject to the foregoing, shall deem most effectual to protect and
enforce any of the rights of the Trustee, the NIM Insurer and the
Certificateholders.

      The Trustee, upon receipt of all resolutions, certificates, statements,
opinions, reports, documents, orders or other instruments furnished to the
Trustee that are specifically required to be furnished pursuant to any provision
of this Agreement shall examine them to determine whether they conform on their
face, to the requirements of this Agreement. If any such instrument is found not
to conform, on its face, to the requirements of this Agreement in a material
manner, the Trustee shall notify the person providing such Agreement of such
non-conformance, and if the instrument is not corrected to the Trustee's
satisfaction,

                                      100
<PAGE>

the Trustee will provide notice thereof to the NIM Insurer and the
Certificateholders and take such further action as directed by the NIM Insurer
and the Certificateholders.

      No provision of this Agreement shall be construed to relieve the Trustee
from liability for its own negligent action, its own negligent failure to act or
its own misconduct, its negligent failure to perform its obligations in
compliance with this Agreement, or any liability that would be imposed by reason
of its willful misfeasance or bad faith; provided, however, that:

            (i) prior to the occurrence of an Event of Default, and after the
      curing of all such Events of Default that may have occurred, the duties
      and obligations of the Trustee shall be determined solely by the express
      provisions of this Agreement, the Trustee shall not be liable,
      individually or as Trustee, except for the performance of such duties and
      obligations as are specifically set forth in this Agreement, no implied
      covenants or obligations shall be read into this Agreement against the
      Trustee and the Trustee may conclusively rely, as to the truth of the
      statements and the correctness of the opinions expressed therein, upon any
      certificates or opinions furnished to the Trustee and conforming to the
      requirements of this Agreement that it reasonably believed in good faith
      to be genuine and to have been duly executed by the proper authorities
      respecting any matters arising hereunder;

            (ii) the Trustee shall not be liable, individually or as Trustee,
      for an error of judgment made in good faith by a Responsible Officer or
      Responsible Officers of the Trustee, unless the Trustee was negligent or
      acted in bad faith or with willful misfeasance;

            (iii) the Trustee shall not be liable, individually or as Trustee,
      with respect to any action taken, suffered or omitted to be taken by it in
      good faith in accordance with the direction of the NIM Insurer or the
      Holders of each Class of Certificates evidencing not less than 50% of the
      Voting Rights of such Class relating to the time, method and place of
      conducting any proceeding for any remedy available to the Trustee, or
      exercising any trust or power conferred upon the Trustee under this
      Agreement; and

            (iv) except as otherwise expressly provided in this Agreement, if
      any default occurs in the making of a payment due under any Permitted
      Investment, or if a default occurs in any other performance required under
      any Permitted Investment, the Trustee may and, subject to Section 8.01 and
      Section 8.02, upon the request of the NIM Insurer or the Holders of the
      Certificates representing more than 50% of the Voting Rights allocated to
      any Class of Certificates, shall take such action as may be appropriate to
      enforce such payment or performance, including the institution and
      prosecution of appropriate proceedings.

      The Trustee shall have no duty hereunder with respect to any complaint,
claim, demand, notice or other document it may receive or which may be alleged
to have been delivered to or served upon it by the parties as a consequence of
the assignment of any Mortgage Loan hereunder; provided, however, that the
Trustee shall promptly remit to the Servicer upon receipt any such complaint,
claim, demand, notice or other document (i) which is delivered to the Trustee,
(ii) of which a Responsible Officer has actual knowledge and (iii) which
contains information sufficient to permit the Trustee to make a determination
that the real property to which such document related to is a Mortgaged
Property.

      SECTION 8.02. Certain Matters Affecting the Trustee.

      (a) Except as otherwise provided in Section 8.01:

                                      101
<PAGE>

            (i) the Trustee may request and rely upon and shall be protected in
      acting or refraining from acting upon any resolution, Officer's
      Certificate, certificate of auditors or any other certificate, statement,
      instrument, opinion, report, notice, request, consent, order, appraisal,
      bond or other paper or document believed by it to be genuine and to have
      been signed or presented by the proper party or parties;

            (ii) the Trustee may consult with counsel of its choice and any
      advice or Opinion of Counsel shall be full and complete authorization and
      protection in respect of any action taken or suffered or omitted by it
      hereunder in good faith and in accordance with such advice or Opinion of
      Counsel;

            (iii) the Trustee shall not be liable, individually or as Trustee,
      for any action taken, suffered or omitted by it in good faith and believed
      by it to be authorized or within the discretion or rights or powers
      conferred upon it by this Agreement;

            (iv) prior to the occurrence of an Event of Default hereunder and
      after the curing of all Events of Default that may have occurred, the
      Trustee shall not be bound to make any investigation into the facts or
      matters stated in any resolution, certificate, statement, instrument,
      opinion, report, notice, request, consent, order, approval, bond or other
      paper or document, unless requested in writing so to do by the NIM Insurer
      or the Holders of each Class of Certificates evidencing not less than 50%
      of the Voting Rights of such Class;

            (v) the Trustee may execute any of the trusts or powers hereunder or
      perform any duties hereunder either directly or by or through agents,
      accountants or attorneys;

            (vi) the Trustee shall not be required to expend its own funds or
      otherwise incur any financial liability in the performance of any of its
      duties hereunder if it shall have reasonable grounds for believing that
      repayment of such funds or adequate indemnity against such liability is
      not assured to it;

            (vii) the Trustee shall not be liable, individually or as Trustee,
      for any loss on any investment of funds pursuant to this Agreement (other
      than as issuer of the investment security);

            (viii) the Trustee shall not be deemed to have knowledge of an Event
      of Default until a Responsible Officer of the Trustee shall have received
      written notice thereof,

            (ix) the Trustee shall be under no obligation to exercise any of the
      trusts or powers vested in it by this Agreement or to make any
      investigation of matters arising hereunder or to institute, conduct or
      defend any litigation hereunder or in relation hereto at the request,
      order or direction of any of the NIM Insurer or the Certificateholders,
      pursuant to the provisions of this Agreement, unless the NIM Insurer or
      such Certificateholders shall have offered to the Trustee reasonable
      security or indemnity against the costs, expenses and liabilities that may
      be incurred therein or thereby; and

            (x) if requested by the Servicer, the Trustee may appoint the
      Servicer as the trustee's attorney-in-fact in order to carry out and
      perform certain activities that are necessary or appropriate for the
      servicing and administration of the Mortgage Loans pursuant to this
      Agreement. Such appointment shall be evidenced by a power of attorney in
      such form as may be agreed to by the Trustee and the Servicer. The Trustee
      shall have no liability for any action or inaction of the Servicer in
      connection with such power of attorney and the Trustee shall be

                                      102
<PAGE>

      indemnified by the Servicer for all liabilities, costs and expenses
      incurred by the Trustee in connection with the Servicer's use or misuse of
      such powers of attorney.

      (b) All rights of action under this Agreement or under any of the
Certificates, enforceable by the Trustee, may be enforced by the Trustee without
the possession of any of the Certificates, or the production thereof at the
trial or other proceeding relating thereto, and any such suit, action or
proceeding instituted by the Trustee shall be brought in its name for the
benefit of all the Holders of the Certificates, subject to the provisions of
this Agreement.

      SECTION 8.03. Trustee Not Liable for Mortgage Loans.

      The recitals contained herein shall be taken as the statements of the
Depositor or the Servicer, as the case may be, and the Trustee assumes no
responsibility for their correctness. The Trustee makes no representations as to
the validity or sufficiency of this Agreement, of any Mortgage Loan, of any
guarantee of a NIM Insurer or related document other than with respect to the
Trustee's execution and authentication of the Certificates. The Trustee shall
not be accountable for the use or application by the Depositor or the Servicer
of any funds paid to the Depositor or the Servicer in respect of the Mortgage
Loans or deposited in or withdrawn from the Collection Account or Certificate
Account by the Depositor or the Servicer.

      SECTION 8.04. Trustee May Own Certificates.

      The Trustee in its individual or any other capacity may become the owner
or pledgee of Certificates with the same rights as it would have if it were not
the Trustee.

      SECTION 8.05. Trustee's Fees.

      The Trustee shall be entitled to earnings on or investment income with
respect to funds in or credited to the Certificate Account.

      SECTION 8.06. Indemnification of Trustee; Expenses.

      (a) The Trustee and its respective directors, officers, employees and
agents shall be entitled to indemnification from the Trust Fund for any loss,
liability or expense incurred in connection with any legal proceeding or
incurred without negligence or willful misconduct on their part, arising out of,
or in connection with, the acceptance or administration of the trusts created
hereunder or in connection with the performance of their duties hereunder,
including any applicable fees and expenses payable hereunder and the costs and
expenses of defending themselves against any claim in connection with the
exercise or performance of any of their powers or duties hereunder, provided
that:

            (i) with respect to any such claim, the Trustee shall have given the
      Depositor and the Holders written notice thereof promptly after the
      Trustee shall have knowledge thereof; provided that failure to so notify
      shall not relieve the Trust Fund of the obligation to indemnify the
      Trustee; however, any reasonable delay by the Trustee to provide written
      notice to the Depositor and the Holders promptly after the Trustee shall
      have obtained knowledge of a claim shall not relieve the Trust Fund of the
      obligation to indemnify the Trustee under this Section 8.06;

            (ii) while maintaining control over its own defense, the Trustee
      shall cooperate and consult fully with the Depositor in preparing such
      defense;

                                      103
<PAGE>

            (iii) notwithstanding anything to the contrary in this Section 8.06,
      the Trust Fund shall not be liable for settlement of any such claim by the
      Trustee entered into without the prior consent of the Depositor, which
      consent shall not be unreasonably withheld; and

            (iv) any such loss, liability or expense to be indemnified by the
      Trust Fund must constitute an "unanticipated expense" of the Trust Fund
      within the meaning of Treasury Regulations Section 1.860G-1(b)(3)(ii).

      The provisions of this Section 8.06 shall survive any termination of this
Agreement and the resignation or removal of the Trustee and shall be construed
to include, but not be limited to any loss, liability or expense under any
environmental law.

      (b) The Trustee shall be entitled to all reasonable expenses,
disbursements and advancements incurred or made by the Trustee in accordance
with this Agreement (including fees and expenses of its counsel and all persons
not regularly in its employment), except any such expenses, disbursements and
advancements that either (i) arise from its negligence, bad faith or willful
misconduct or (ii) do not constitute "unanticipated expenses" within the meaning
of Treasury Regulations Section 1.860G-1(b)(3)(ii).

      (c) The Trustee's right to indemnification and reimbursement shall be
subject to a cap of $300,000, excluding any Servicing Transfer Costs and any
auction expenses incurred by the Trustee in connection with Section 9.01(a)(i),
in the aggregate in any calendar year; provided, however, that such cap shall
apply only if NIM Notes have been issued and are outstanding and shall cease to
apply after the date on which any NIM Notes are paid in full and all amounts
which the NIM Insurer is entitled to be paid or reimbursed shall have been paid
or reimbursed. Any amounts not in excess of this cap may be withdrawn by the
Trustee from the Certificate Account at any time.

      SECTION 8.07. Eligibility Requirements for Trustee.

      The Trustee hereunder shall, at all times, be a corporation or association
organized and doing business under the laws of a state or the United States of
America, authorized under such laws to exercise corporate trust powers having a
combined capital and surplus of at least $50,000,000, subject to supervision or
examination by federal or state authority and with a credit rating that would
not cause any of the Rating Agencies to reduce their respective ratings of any
Class of Certificates below the ratings issued on the Closing Date (or having
provided such security from time to time as is sufficient to avoid such
reduction) and reasonably acceptable to the NIM Insurer. If such corporation or
association publishes reports of condition at least annually, pursuant to law or
to the requirements of the aforesaid supervising or examining authority, then
for the purposes of this Section 8.07 the combined capital and surplus of such
corporation or association 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 Trustee shall cease to be eligible in accordance with the
provisions of this Section 8.07, the Trustee shall resign immediately in the
manner and with the effect specified in Section 8.08 hereof. The corporation or
national banking association serving as Trustee may have normal banking and
trust relationships with the Depositor and the NIM Insurer and their respective
Affiliates; provided, however, that such corporation cannot be an Affiliate of
the Servicer other than the Trustee in its role as successor to the Servicer.

      SECTION 8.08. Resignation and Removal of Trustee.

      The Trustee may at any time resign and be discharged from the trusts
hereby created by (1) giving written notice of resignation to the Depositor and
the NIM Insurer and by mailing notice of resignation by first class mail,
postage prepaid, to the Certificateholders at their addresses appearing on

                                      104
<PAGE>

the Certificate Register and each Rating Agency, not less than 60 days before
the date specified in such notice when, subject to Section 8.09, such
resignation is to take effect, and (2) acceptance of appointment by a successor
trustee acceptable to the NIM Insurer in accordance with Section 8.09 and
meeting the qualifications set forth in Section 8.07. If no successor trustee
shall have been so appointed and have accepted appointment within 30 days after
the giving of such notice or resignation, the resigning Trustee may petition any
court of competent jurisdiction for the appointment of a successor trustee.

      If at any time (i) the Trustee shall cease to be eligible in accordance
with the provisions of Section 8.07 hereof and shall fail to resign after
written request thereto by the Depositor or the NIM Insurer, (ii) the Trustee
shall become incapable of acting, or shall be adjudged as bankrupt or insolvent,
or a receiver of the Trustee or of its property shall be appointed, or any
public officer shall take charge or control of the Trustee or of its property or
affairs for the purpose of rehabilitation, conservation or liquidation, or
(iii)(A) a tax is imposed with respect to the Trust Fund by any state in which
the Trustee or the Trust Fund is located, (B) the imposition of such tax would
be avoided by the appointment of a different trustee and (C) the Trustee fails
to indemnify the Trust Fund against such tax, then the Depositor or the NIM
Insurer may remove the Trustee and the Depositor with the consent of the NIM
Insurer shall promptly appoint a successor trustee by written instrument, in
triplicate, one copy of which instrument shall be delivered to the Trustee, one
copy of which shall be delivered to the Servicer and one copy of which shall be
delivered to the successor trustee.

      The Holders evidencing at least 51% of the Voting Rights of all Classes of
Certificates, with the consent of the NIM Insurer, or the NIM Insurer upon
failure of the Trustee to perform its obligations hereunder may at any time
remove the Trustee and the Depositor shall appoint a successor trustee by
written instrument or instruments, in triplicate, signed by such Holders or
their attorneys-in-fact duly authorized (or by the NIM Insurer), one complete
set of which instruments shall be delivered by the successor Trustee to the
Servicer, one complete set to the Trustee so removed and one complete set to the
successor so appointed. Notice of any removal of the Trustee shall be given to
the NIM Insurer and each Rating Agency by the Successor Trustee.

      Any resignation or removal of the Trustee and appointment of a successor
trustee pursuant to any of the provisions of this Section 8.08 shall become
effective upon acceptance of appointment by the successor trustee as provided in
Section 8.09 hereof.

      SECTION 8.09. Successor Trustee.

      Any successor trustee appointed as provided in Section 8.08 hereof shall
execute, acknowledge and deliver to the Depositor and to its predecessor
trustee, the NIM Insurer and the Servicer an instrument accepting such
appointment hereunder and thereupon the resignation or removal of the
predecessor trustee shall become effective and such successor trustee, without
any further act, deed or conveyance, shall become fully vested with all the
rights, powers, duties and obligations of its predecessor hereunder, with the
like effect as if originally named as trustee herein.

      No successor trustee shall accept appointment as provided in this Section
8.09 unless at the time of such acceptance such successor trustee shall be
eligible under the provisions of Section 8.07 hereof and its appointment shall
not adversely affect the then current rating of the Certificates.

      Upon acceptance of appointment by a successor trustee as provided in this
Section 8.09, the Depositor shall mail notice of the succession of such trustee
hereunder to all Holders of Certificates. If the Depositor fails to mail such
notice within ten days after acceptance of appointment by the successor trustee,
the successor trustee shall cause such notice to be mailed at the expense of the
Depositor.

                                      105

      SECTION 8.10. Merger or Consolidation of Trustee.

      Any corporation into which the 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 Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided that such corporation shall be eligible under the provisions of Section
8.07 hereof without the execution or filing of any paper or further act on the
part of any of the parties hereto, anything herein to the contrary
notwithstanding (except for the execution of an assumption agreement where such
succession is not effected by operation of law).

      SECTION 8.11. Appointment of Co-Trustee or Separate Trustee.

      Notwithstanding any other provisions of this Agreement, at any time, for
the purpose of meeting any legal requirements of any jurisdiction in which any
part of the Trust Fund or property securing any Mortgage Note may at the time be
located, the Servicer and the Trustee acting jointly shall have the power and
shall execute and deliver all instruments to appoint one or more Persons
approved by the Trustee and the NIM Insurer to act as co-trustee or co-trustees
jointly with the Trustee, or separate trustee or separate trustees, of all or
any part of the Trust Fund, and to vest in such Person or Persons, in such
capacity and for the benefit of the Certificateholders, such title to the Trust
Fund or any part thereof, whichever is applicable, and, subject to the other
provisions of this Section 8.11, such powers, duties, obligations, rights and
trusts as the Servicer and the Trustee may consider necessary or desirable. Any
such co-trustee or separate trustee shall be subject to the written approval of
the Servicer and the NIM Insurer. The Trustee shall not be liable for the
actions of any co-trustee appointed at the request of the Trustee provided that
such co-trustee has been appointed with due care. If the Servicer and the NIM
Insurer shall not have joined in such appointment within 15 days after the
receipt by it of a request to do so, or in the case an Event of Default shall
have occurred and be continuing, the Trustee alone shall have the power to make
such appointment. No co-trustee or separate trustee hereunder shall be required
to meet the terms of eligibility as a successor trustee under Section 8.07 and
no notice to Certificateholders of the appointment of any co-trustee or separate
trustee shall be required under Section 8.09.

      Every 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 Trustee, except for the obligation of the Trustee under this
      Agreement to advance funds on behalf of the Servicer, shall be conferred
      or imposed upon and exercised or performed by the 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 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 (whether as Trustee hereunder or as successor to the Servicer
      hereunder), the 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 Fund 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 Trustee;

            (ii) No trustee hereunder shall be held personally liable by reason
      of any act or omission of any other trustee hereunder; and

            (iii) The Trustee with the consent of the NIM Insurer may at any
      time accept the resignation of or remove any separate trustee or
      co-trustee.

                                      106
<PAGE>

      Any notice, request or other writing given to the 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 VIII. 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 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 Trustee. Every
such instrument shall be filed with the Trustee and a copy thereof given to the
Servicer, the NIM Insurer and the Depositor.

      Any separate trustee or co-trustee may, at any time, constitute the
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
Trustee, to the extent permitted by law, without the appointment of a new or
successor trustee.

      SECTION 8.12. Tax Matters.

      It is intended that each of the REMICs provided for herein shall
constitute, and that the affairs of the Trust Fund shall be conducted so as to
allow each such REMIC to qualify as, a "real estate mortgage investment conduit"
as defined in and in accordance with the REMIC Provisions. It is also intended
that each of the grantor trusts provided for in Section 2.07 hereof shall
constitute, and that the affairs of Trust Fund shall be conducted so as to allow
each such grantor trust to qualify as, a grantor trust under the provisions of
Subpart E, Part I of Subchapter J of the Code. In furtherance of such intention,
the Trustee covenants and agrees that it shall act as agent (and the Trustee is
hereby appointed to act as agent) on behalf of each of the REMICs provided for
herein and that in such capacity it shall: (a) prepare and file, or cause to be
prepared and filed, in a timely manner, a U.S. Real Estate Mortgage Investment
Conduit Income Tax Return (Form 1066 or any successor form adopted by the
Internal Revenue Service) and prepare and file or cause to be prepared and filed
with the Internal Revenue Service and applicable state or local tax authorities
income tax or information returns for each taxable year with respect to each of
the REMICs and grantor trusts provided for herein, containing such information
and at the times and in the manner as may be required by the Code or state or
local tax laws, regulations, or rules, and furnish or cause to be furnished to
Certificateholders the schedules, statements or information at such times and in
such manner as may be required thereby; (b) within thirty days of the Closing
Date, furnish or cause to be furnished to the Internal Revenue Service, on Forms
8811 or as otherwise may be required by the Code, the name, title, address, and
telephone number of the person that the holders of the Certificates may contact
for tax information relating thereto, together with such additional information
as may be required by such Form, and update such information at the time or
times in the manner required by the Code for each of the REMICs provided for
herein; (c) make or cause to be made elections, on behalf of each of the REMICs
provided for herein to be treated as a REMIC on the federal tax return of such
REMICs for their first taxable years (and, if necessary, under applicable state
law); (d) prepare and forward, or cause to be prepared and forwarded, to the
Certificateholders and to the Internal Revenue Service and, if necessary, state
tax authorities, all information returns and reports as and when required to be
provided to them in accordance with the REMIC Provisions or other applicable tax
law, including without limitation, the calculation of any original issue
discount using the Prepayment Assumption; (e) provide information necessary for
the computation of tax imposed on the transfer of a Class R Certificate to a
Person that is not a Permitted Transferee, or an agent (including a broker,
nominee or other middleman) of a Person that is not a Permitted Transferee, or a
Pass-through entity in which a Person that is not a Permitted Transferee is the
record holder of an interest (the reasonable cost of computing and furnishing
such information may be charged to the Person liable for such tax); (f) to the
extent that they are under its control conduct the

                                      107
<PAGE>

affairs of each of the REMICs and grantor trusts provided for herein at all
times that any Certificates are outstanding so as to maintain the status of each
of the REMICs provided for herein as a REMIC under the REMIC Provisions and the
status of each of the grantor trusts provided for herein as a grantor trust
under Subpart E, Part I of Subchapter J of the Code; (g) not knowingly or
intentionally take any action or omit to take any action that would cause the
termination of the REMIC status of any of the REMICs provided for herein or
result in the imposition of tax upon any such REMIC; (h) not knowingly or
intentionally take any action or omit to take any action that would cause the
termination of the grantor trust status under Subpart E, Part I of Subchapter J
of the Code of any of the grantor trusts provided for herein or result in the
imposition of tax upon any such grantor trust; (i) pay, from the sources
specified in the last paragraph of this Section 8.12, the amount of any federal,
state and local taxes, including prohibited transaction taxes as described
below, imposed on each of the REMICs provided for herein prior to the
termination of the Trust Fund when and as the same shall be due and payable (but
such obligation shall not prevent the Trustee or any other appropriate Person
from contesting any such tax in appropriate proceedings and shall not prevent
the Trustee from withholding payment of such tax, if permitted by law, pending
the outcome of such proceedings); (j) sign or cause to be signed federal, state
or local income tax or information returns; (k) maintain records relating to
each of the REMICs provided for herein, including but not limited to the income,
expenses, assets and liabilities of each of the REMICs provided for herein, and
the fair market value and adjusted basis of the Trust Fund property determined
at such intervals as may be required by the Code, as may be necessary to prepare
the foregoing returns, schedules, statements or information; and (l) as and when
necessary and appropriate, represent each of the REMICs and grantor trusts
provided for herein in any administrative or judicial proceedings relating to an
examination or audit by any governmental taxing authority, request an
administrative adjustment as to any taxable year of any of the REMICs provided
for herein, enter into settlement agreements with any governmental taxing
agency, extend any statute of limitations relating to any tax item of any of the
REMICs provided for herein, and otherwise act on behalf of each of the REMICs
provided for herein in relation to any tax matter involving any of such REMICs
or any controversy involving the Trust Fund.

      In order to enable the Trustee to perform its duties as set forth herein,
the Depositor shall provide, or cause to be provided, to the Trustee within 10
days after the Closing Date all information or data that the Trustee requests in
writing and determines to be relevant for tax purposes to the valuations and
offering prices of the Certificates, including, without limitation, the price,
yield, prepayment assumption and projected cash flows of the Certificates and
the Mortgage Loans. Thereafter, the Depositor shall provide to the Trustee
promptly upon written request therefor, any such additional information or data
that the Trustee may, from time to time, request in order to enable the Trustee
to perform its duties as set forth herein. The Depositor hereby agrees to
indemnify the Trustee for any losses, liabilities, damages, claims or expenses
of the Trustee arising from any errors or miscalculations of the Trustee that
result from any failure of the Depositor to provide, or to cause to be provided,
accurate information or data to the Trustee on a timely basis.

      In the event that any tax is imposed on "prohibited transactions" of any
of the REMICs provided for herein as defined in Section 860F(a)(2) of the Code,
on the "net income from foreclosure property" of any of such REMICs as defined
in Section 860G(c) of the Code, on any contribution to the Trust Fund after the
Startup Day pursuant to Section 860G(d) of the Code, or any other tax is
imposed, if not paid as otherwise provided for herein, such tax shall be paid by
(i) the Trustee, if any such other tax arises out of or results from a breach by
the Trustee of any of its obligations under this Agreement or as a result of the
location of the Trustee, (ii) any party hereto (other than the Trustee) to the
extent any such other tax arises out of or results from a breach by such other
party of any of its obligations under this Agreement or as a result of the
location of such other party or (iii) in all other cases, or in the event that
any liable party here fails to honor its obligations under the preceding clauses
(i) or (ii), any such tax will be paid first with amounts otherwise to be
distributed to the Class R Certificateholders (pro rata) pursuant to Section
4.04, and second with amounts otherwise to be distributed to all other
Certificateholders in the following order

                                      108
<PAGE>

of priority: first, to the Class C Certificates (pro rata), second, to the Class
B-3 Certificates (pro rata), third, to the Class B-2 Certificates (pro rata),
fourth to the Class B-1 Certificates (pro rata), fifth, to the Class M-3
Certificates (pro rata), sixth, to the Class M-2 Certificates (pro rata),
seventh, to the Class M-1 Certificates (pro rata), and eighth, to the Class A
Certificates (pro rata). Notwithstanding anything to the contrary contained
herein, to the extent that such tax is payable by the Class R Certificate, the
Trustee is hereby authorized pursuant to such instruction to retain on any
Distribution Date, from the Holders of the Class R Certificate (and, if
necessary, from the Holders of all other Certificates in the priority specified
in the preceding sentence), funds otherwise distributable to such Holders in an
amount sufficient to pay such tax. The Trustee agrees to promptly notify in
writing the party liable for any such tax of the amount thereof and the due date
for the payment thereof.

      (a) Each of the Depositor and the Trustee agrees not to knowingly or
intentionally take any action or omit to take any action that would cause the
termination of the REMIC status of any of the REMICs provided for herein or
result in the imposition of a tax upon any of the REMICs provided for herein.

                                   ARTICLE IX
                                   TERMINATION

      SECTION 9.01. Termination upon Liquidation or Repurchase of all Mortgage
Loans.

      (a) Subject to Section 9.03, the obligations and responsibilities of the
Depositor, the Servicer and the Trustee created hereby with respect to the Trust
Fund shall terminate upon the earliest of (i) the successful completion of the
auction referred to in Section 9.01(b), (ii) the exercise by the NIM Insurer (or
the Servicer) of the Clean Up Call on any Distribution Date on or after the
Clean Up Call Date and (iii) the later of (x) the maturity or other liquidation
(or any Advance with respect thereto) of the last Mortgage Loan remaining in the
Trust Fund and the disposition of all REO Property and (y) the distribution to
Certificateholders of all amounts required to be distributed to them pursuant to
this Agreement, as applicable. In no event shall the trusts created hereby
continue beyond the earlier of (i) the expiration of 21 years from the death of
the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador
of the United States to the Court of St. James's, living on the date hereof and
(ii) the Latest Possible Maturity Date.

      (b)   (i) Any termination pursuant to Section 9.01(a)(i) shall be effected
by the auction by the Trustee of all of the Mortgage Loans and REO Properties
via a solicitation of bids in accordance with the auction procedures set forth
in Exhibit N. The Trustee shall accept the highest such bid, provided that such
bid equals or exceeds the amount described in the definition of "Auction
Termination Price." Any sale pursuant to such auction process must occur no
earlier than the second day of the calendar month that includes the Distribution
Date on which the proceeds of such sale will be distributed to the
Certificateholders.

            (ii) If no sale under Section 9.01(a)(i) occurs, the NIM Insurer (or
the Servicer as provided in clause (e) below) may, at its option, terminate the
Trust Fund on any Distribution Date by purchasing all of the Mortgage Loans and
REO Properties at the price equal to the Clean Up Call Price.

Notwithstanding anything to the contrary herein, the Auction Termination Amount
received by the Trustee or the Clean Up Call Price paid by the NIM Insurer or
the Servicer shall be deposited by the Trustee directly into the Certificate
Account promptly upon receipt of such amount by the Trustee. Any Clean Up Call
Price to be paid by the NIM Insurer or the Servicer shall be paid by the NIM
Insurer or the Servicer to the Trustee for deposit into the Certificate Account.

                                      109
<PAGE>

      (c) If the Trustee receives a bid meeting the conditions specified in
Section 9.01(b)(i) or there is a Clean Up Call pursuant to Section 9.01(b)(ii),
then the Trustee's written acceptance of such bid shall constitute a plan of
complete liquidation within the meaning of Section 860F of the Code, and the
Trustee shall release to the winning bidder of the auction or the purchaser
pursuant to the Clean Up Call, upon the Trustee's receipt of the Auction
Termination Price or the Clean Up Call Price and the distribution by the Trustee
of such amounts in accordance with Section 4.04 hereof, the Mortgage Files
pertaining to the Mortgage Loans being purchased and take such other actions as
the winning bidder or such purchaser may reasonably request to effect the
transfer of the Mortgage Loans to the winning bidder or such purchaser.

      In connection with any such purchase pursuant to the preceding paragraph,
the Servicer shall deposit in the Certificate Account all amounts then on
deposit in the Collection Account (less amounts permitted to be withdrawn by the
Servicer pursuant to Section 3.08), which deposit shall be deemed to have
occurred immediately preceding such purchase.

      Any purchase shall be accomplished by deposit into the Certificate Account
of the amount paid by the winning bidder if an Auction Termination has occurred
or the amount described in the definition of "Clean Up Call Price" and only
following the delivery of an Opinion of Counsel in form and substance acceptable
to the Trustee that such termination is a "Qualified Liquidation" under Section
860F of the Code.

      (d) The right of the Depositor to direct the Trustee to effect an Auction
Termination or of the NIM Insurer or the Servicer to effect a Clean Up Call
pursuant to clause (a)(i) or (a)(ii) above shall be conditioned upon the
aggregate Stated Principal Balance of the Mortgage Loans, at the time of any
such repurchase, aggregating ten percent (10%) or less of the Stated Principal
Balance of the Mortgage Loans as of the Cut-off Date.

      (e) In the event that the Trustee is unable to complete a sale at the
Auction Termination and the NIM Insurer does not exercise a Clean Up Call, the
Servicer may terminate the Trust Fund by purchasing all the Mortgage Loans, and
REO Properties at a price equal to the Clean Up Call Price on any Distribution
Date on or after the Clean Up Call Date, by exercising a Clean Up Call.

      (f) The Class R Certificateholder hereby assigns to the Class C
Certificateholders that portion of any amount received by the Class R
Certificate upon an Auction Termination or Clean Up Call of the Trust Fund that
is attributable to clause (C) of the definition of Auction Termination Price or
clause (c) of the definition of Clean Up Call Price and required to cover what
would otherwise be a shortfall in the amounts described in clause (C) of the
definition of Auction Termination Price or clause (c) of the definition of Clean
Up Call Price.

      SECTION 9.02. Final Distribution on the Certificates.

      If on any Determination Date, (i) the Trustee determines that there are no
Outstanding Mortgage Loans and no other funds or assets in the Trust Fund other
than the funds in the Collection Account, the Trustee shall send a final
distribution notice promptly to each Certificateholder and the NIM Insurer or
(ii) the Trustee determines that a Class of Certificates shall be retired after
a final distribution on such Class, the Trustee shall notify the
Certificateholders within seven (7) Business Days after such Determination Date
that the final distribution in retirement of such Class of Certificates is
scheduled to be made on the immediately following Distribution Date. Any final
distribution made pursuant to the immediately preceding sentence will be made
only upon presentation and surrender of the Certificates at the office of the
Trustee specified in such notice. If the Trustee is able to terminate the Trust
Fund pursuant to Section 9.01(a)(i), or if the NIM Insurer or the Servicer
conducts a Clean Up Call and

                                      110
<PAGE>

terminates the Trust Fund pursuant to Section 9.01(a)(ii) or 9.01(e), at least
10 days prior to the date notice is to be mailed to the affected
Certificateholders, the Trustee shall notify the Depositor and the Servicer of
the date such electing party intends to terminate the Trust Fund and of the
applicable repurchase price of the Mortgage Loans and REO Properties.

      Notice of any termination of the Trust Fund, specifying the Distribution
Date on which Certificateholders may surrender their Certificates for payment of
the final distribution and cancellation, shall be given promptly by the Trustee
by letter to Certificateholders mailed not earlier than the 10th day and no
later than the 15th day of the month immediately preceding the month of such
final distribution. Any such notice shall specify (a) the Distribution Date upon
which final distribution on the Certificates will be made upon presentation and
surrender of Certificates at the office therein designated, (b) the location of
the office or agency at which such presentation and surrender must be made, and
(c) that the Record Date otherwise applicable to such Distribution Date is not
applicable, distributions being made only upon presentation and surrender of the
Certificates at the office therein specified. The Trustee will give such notice
to the NIM Insurer and each Rating Agency at the time such notice is given to
Certificateholders.

      In the event such notice is given, the Servicer shall cause all funds in
the Collection Account to be deposited in the Certificate Account on the
Business Day prior to the applicable Distribution Date in an amount equal to the
final distribution in respect of the Certificates. Upon such final deposit with
respect to the Trust Fund and the receipt by the Trustee of a Request for
Release therefor, the Trustee shall promptly release to the Trustee or the NIM
Insurer, as applicable, the Mortgage Files for the Mortgage Loans.

      Upon presentation and surrender of the Certificates, the Trustee shall
cause to be distributed to Certificateholders of each Class the amounts
allocable to such Certificates held in the Certificate Account in the order and
priority set forth in Section 4.04 hereof on the final Distribution Date and in
proportion to their respective Percentage Interests.

      In the event that any affected Certificateholders shall not surrender
Certificates for cancellation within six months after the date specified in the
above mentioned written notice, the Trustee shall give a second written notice
to the remaining Certificateholders to surrender their Certificates for
cancellation and receive the final distribution with respect thereto. If within
six months after the second notice all the applicable Certificates shall not
have been surrendered for cancellation, the Trustee may take appropriate steps,
or may appoint an agent to take appropriate steps, to contact the remaining
Certificateholders concerning surrender of their Certificates, and the cost
thereof shall be paid out of the funds and other assets that remain a part of
the Trust Fund. If within one year after the second notice all Certificates
shall not have been surrendered for cancellation, the Class R Certificateholders
shall be entitled to all unclaimed funds and other assets of the Trust Fund that
remain subject hereto. Upon payment to the Class R Certificateholders of such
funds and assets, the Trustee shall have no further duties or obligations with
respect thereto.

      SECTION 9.03. Additional Termination Requirements.

      (a) In the event the Trustee is able to effect an Auction Termination or
the NIM Insurer or the Servicer conducts a Clean Up Call as provided in Section
9.01, the Trust Fund shall be terminated in accordance with the following
additional requirements, unless the Trustee has been supplied with an Opinion of
Counsel addressed to the Trustee, at the expense of the Trust Fund or the NIM
Insurer, as applicable, to the effect that the failure of the Trust Fund to
comply with the requirements of this Section 9.03 will not (i) result in the
imposition of taxes on "prohibited transactions" of any of the REMICs

                                      111
<PAGE>

provided for herein as defined in section 860F of the Code, or (ii) cause any of
the REMICs provided for herein to fail to qualify as a REMIC at any time that
any Certificates are outstanding:

            (i) The Depositor shall establish a 90-day liquidation period and
      notify the Trustee thereof, which shall in turn specify the first day of
      such period in a statement attached to the final tax returns of each of
      the REMICs provided for herein pursuant to Treasury Regulation Section
      1.860F-1. The Depositor shall satisfy all the requirements of a qualified
      liquidation under Section 860F of the Code and any regulations thereunder,
      as evidenced by an Opinion of Counsel obtained at the expense of the Trust
      Fund or the NIM Insurer, as applicable;

            (ii) During such 90-day liquidation period, and at or prior to the
      time of making the final payment on the Certificates, the Depositor as
      agent of the Trustee shall sell all of the assets of the Trust Fund for
      cash; and

            (iii) At the time of the making of the final payment on the
      Certificates, the Trustee shall distribute or credit, or cause to be
      distributed or credited, to the Class R Certificateholders all cash on
      hand (other than cash retained to meet outstanding claims known to the
      Trustee), and the Trust Fund shall terminate at that time, whereupon the
      Trustee shall have no further duties or obligations with respect to sums
      distributed or credited to the Class R Certificateholders.

      (b) By their acceptance of the Certificates, the Holders thereof hereby
authorize the Depositor to specify the 90-day liquidation period for the Trust
Fund, which authorization shall be binding upon all successor
Certificateholders.

      (c) The Trustee as agent for each REMIC hereby agrees to adopt and sign a
plan of complete liquidation prepared and delivered to it by the Depositor upon
the written request of the Depositor, and the receipt of Opinion of Counsel
referred to in Section 9.03(a)(i) and to take such other action in connection
therewith as may be reasonably requested by the Depositor.

                                    ARTICLE X
                            MISCELLANEOUS PROVISIONS

      SECTION 10.01. Amendment.

      This Agreement may be amended from time to time by the Depositor, the
Servicer and the Trustee, with the consent of the NIM Insurer and without the
consent of any of the Certificateholders to,

            (i) To cure any ambiguity or correct any mistake,

            (ii) To correct, modify or supplement any provision therein which
      may be inconsistent with any other provision herein,

            (iii) To add any other provisions with respect to matters or
      questions arising under this Agreement, or

            (iv) To modify, alter, amend, add to or rescind any of the terms or
      provisions contained in this Agreement, provided, however, that, in the
      case of clauses (iii) and (iv), such amendment will not, as evidenced by
      an Opinion of Counsel addressed to the Trustee to such effect, adversely
      effect in any material respect the interests of any Holder; provided,
      further, however, that such amendment will be deemed to not adversely
      affect in any material respect the interest of any Holder if the Person
      requesting such amendment obtains a letter from each Rating

                                      112
<PAGE>

      Agency stating that such amendment will not result in a reduction or
      withdrawal of its rating of any Class of the Certificates, it being
      understood and agreed that any such letter in and of itself will not
      represent a determination as to the materiality of any such amendment and
      will represent a determination only as to the credit issues affecting any
      such rating.

      Notwithstanding the foregoing, without the consent of the
Certificateholders, the Depositor, the Servicer and the Trustee may at any time
and from time to time amend this Agreement to modify, eliminate or add to any of
its provisions to such extent as shall be necessary or appropriate to maintain
the qualification of any of the REMICs provided for herein as REMICs under the
Code or to avoid or minimize the risk of the imposition of any tax on the Trust
Fund or any of the REMICs provided for herein pursuant to the Code that would be
a claim against the Trust Fund at any time prior to the final redemption of the
Certificates, provided that the Trustee and the NIM Insurer have been provided
an Opinion of Counsel addressed to the Trustee, which opinion shall be an
expense of the party requesting such amendment but in any case shall not be an
expense of the Trustee, to the effect that such action is necessary or
appropriate to maintain such qualification or to avoid or minimize the risk of
the imposition of such a tax.

      This Agreement may also be amended from time to time by the Depositor, the
Servicer, the Trustee and the Holders of the Certificates affected thereby
evidencing not less than 66 2/3% of the Voting Rights, with the consent of the
NIM Insurer, 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 Holders of Certificates; provided, however, that no
such amendment shall (i) reduce in any manner the amount of, or delay the timing
of, payments required to be distributed on any Certificate without the consent
of the Holder of such Certificate, (ii) adversely affect in any material respect
the interests of the Holders of any Class of Certificates in a manner other than
as described in (i), without the consent of the Holders of Certificates of such
Class evidencing 66 2/3% or more of the Voting Rights of such Class or (iii)
reduce the aforesaid percentages of Certificates the Holders of which are
required to consent to any such amendment without the consent of the Holders of
all such Certificates then outstanding.

      Notwithstanding any contrary provision of this Agreement, the Trustee
shall not consent to any amendment to this Agreement unless it shall have first
received an Opinion of Counsel addressed to the Trustee, which opinion shall be
an expense of the party requesting such amendment but in any case shall not be
an expense of the Trustee, to the effect that such amendment is permitted
hereunder and will not cause the imposition of any tax on the Trust Fund, any of
the REMICs provided for herein or the Certificateholders or cause any of the
REMICs provided for herein to fail to qualify as a REMIC at any time that any
Certificates are outstanding. A copy of such Opinion of Counsel shall be
provided to the NIM Insurer.

      Promptly after the execution of any amendment to this Agreement requiring
the consent of Certificateholders, the Trustee or upon the written request of
the Trustee to the Servicer, the Servicer shall furnish written notification of
the substance of such amendment to each Certificateholder, the NIM Insurer and
each Rating Agency.

      It shall not be necessary for the consent of Certificateholders under this
Section to approve the particular form of any proposed amendment, but it shall
be sufficient if such consent shall approve the substance thereof. The manner of
obtaining such consents and of evidencing the authorization of the execution
thereof by Certificateholders shall be subject to such reasonable regulations as
the Trustee may prescribe.

                                      113
<PAGE>

      Nothing in this Agreement shall require the Trustee or the Servicer to
enter into an amendment without receiving an Opinion of Counsel, satisfactory to
the Trustee or the Servicer that (i) such amendment is permitted and is not
prohibited by this Agreement and that all requirements for amending this
Agreement have been complied with; and (ii) either (A) the amendment does not
adversely affect in any material respect the interests of any Certificateholder
or (B) the conclusion set forth in the immediately preceding clause (A) is not
required to be reached pursuant to this Section 10.01.

      The Trustee may, but shall not be obligated to, enter into any supplement,
modification or waiver which affects its rights, duties or obligations
hereunder.

      SECTION 10.02. Counterparts.

      This Agreement may be executed simultaneously in any number of
counterparts, each of which counterparts shall be deemed to be an original, and
such counterparts shall constitute but one and the same instrument.

      SECTION 10.03. Governing Law.

      THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE
SUBSTANTIVE LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO
BE PERFORMED IN THE STATE OF NEW YORK AND THE OBLIGATIONS, RIGHTS AND REMEDIES
OF THE PARTIES HERETO AND THE CERTIFICATEHOLDERS SHALL BE DETERMINED IN
ACCORDANCE WITH SUCH LAWS WITHOUT REGARD TO THE CONFLICTS OF LAWS PRINCIPLES
THEREOF.

      SECTION 10.04. Intention of Parties.

      It is the express intent of the parties hereto that the conveyance of the
Mortgage Notes, Mortgages, assignments of Mortgages, title insurance policies
and any modifications, extensions and/or assumption agreements and private
mortgage insurance policies relating to the Mortgage Loans by the Depositor to
the Trustee be, and be construed as, an absolute sale thereof to the Trustee. It
is, further, not the intention of the parties that such conveyance be deemed a
pledge thereof by the Depositor to the Trustee. However, in the event that,
notwithstanding the intent of the parties, such assets are held to be the
property of the Depositor, or if for any other reason this Agreement is held or
deemed to create a security interest in such assets, then (i) this Agreement
shall be deemed to be a security agreement within the meaning of the Uniform
Commercial Code of the State of New York and (ii) the conveyance provided for in
this Agreement shall be deemed to be an assignment and a grant by the Depositor
to the Trustee, for the benefit of the Certificateholders, of a security
interest in all of the assets that constitute the Trust Fund, whether now owned
or hereafter acquired.

      The Depositor for the benefit of the Certificateholders shall, to the
extent consistent with this Agreement, take such actions as may be necessary to
ensure that, if this Agreement were deemed to create a security interest in the
assets of the Trust Fund, such security interest would be deemed to be a
perfected security interest of first priority under applicable law and will be
maintained as such throughout the term of the Agreement. The Depositor shall
arrange for filing any Uniform Commercial Code continuation statements in
connection with any security interest granted or assigned to the Trustee for the
benefit of the Certificateholders.

      Sections 2.02, 2.03 and 3.12;

      SECTION 10.06. Severability of Provisions.

      If any one or more of the covenants, agreements, provisions or terms of
this Agreement shall be for any reason whatsoever held invalid, then such

      SECTION 10.07. Assignment.

      Notwithstanding anything to the contrary contained herein, except as
provided pursuant to Section 6.02, this Agreement may not be assigned by the
Servicer without the prior written consent of the Trustee and Depositor.

      SECTION 10.08. Limitation on Rights of Certificateholders.

      The death or incapacity of any Certificateholder shall not operate to
terminate this Agreement or the Trust Fund, nor entitle such Certificateholder's
legal representative or heirs to claim an accounting or to take any action or
commence any proceeding in any court for a petition or winding up of the Trust
Fund, or otherwise affect the rights, obligations and liabilities of the parties
hereto or any of them.

      No Certificateholder shall have any right to vote (except as provided
herein) or in any manner otherwise control the operation and management of the
Trust Fund, or the obligations of the parties hereto, nor shall anything herein
set forth or contained in the terms of the Certificates be construed so as to
constitute the Certificateholders from time to time as partners or members of an
association; nor shall any Certificateholder be under any liability to any third
party by reason of any action taken by the parties to this Agreement pursuant to
any provision hereof.

      No Certificateholder shall have any right by virtue or by availing itself
of any provisions of this Agreement to institute any suit, action or proceeding
in equity or at law upon or under or with respect to this Agreement, unless such
Holder previously shall have given to the Trustee a written notice of an Event
of Default and of the continuance thereof, as hereinbefore provided, the Holders
of Certificates evidencing not less than 25% of the Voting Rights evidenced by
the Certificates shall also have made written request to the Trustee to
institute such action, suit or proceeding in its own name as Trustee hereunder
and shall have offered to the Trustee such reasonable indemnity as it may
require against the costs, expenses, and liabilities to be incurred therein or
thereby, and the Trustee, for 60 days after its receipt of such notice, request
and offer of indemnity shall have neglected or refused to institute any such
action, suit or proceeding; it being understood and intended, and being
expressly covenanted by each Certificateholder with every other
Certificateholder and the Trustee, that no one or more Holders of Certificates
shall have any right in any manner whatever by virtue or by availing itself or
themselves of any provisions of this Agreement to affect, disturb or prejudice
the rights of the Holders of any other of the Certificates and/or the NIM
Insurer, or to obtain or seek to obtain priority over or preference to any other
such Holder and/or the NIM Insurer or to enforce any right under this Agreement,
except in the manner herein provided and for the common benefit of all
Certificateholders. For the protection and enforcement of the provisions of this
Section 10.08, each and every Certificateholder and the Trustee shall be
entitled to such relief as can be given either at law or in equity.

      SECTION 10.09. Inspection and Audit Rights.

      The Servicer agrees that, on reasonable prior notice, it will permit any
representative of the NIM Insurer, the Depositor or the Trustee during the
Servicer's normal business hours, to examine all the books of account, records,
reports and other papers of the Servicer relating to the Mortgage Loans, to make
copies and extracts therefrom, to cause such books to be audited by independent
certified public accountants selected by the NIM Insurer, Depositor or the
Trustee and to discuss its affairs, finances and accounts relating to the
Mortgage Loans with its officers, employees, agents, counsel and independent
public accountants (and by this provision the Servicer hereby authorizes such
accountants to discuss with such representative such affairs, finances and
accounts), all at such reasonable times and as often as may be reasonably
requested. Any out-of-pocket expense incident to the exercise by the NIM
Insurer,

                                      116
<PAGE>

Depositor or the Trustee of any right under this Section 10.09 shall be borne by
the party requesting such inspection; all other such expenses shall be borne by
the Servicer.

      SECTION 10.10. Certificates Nonassessable and Fully Paid.

      It is the intention of the Depositor that Certificateholders shall not be
personally liable for obligations of the Trust Fund, that the interests in the
Trust Fund represented by the Certificates shall be nonassessable for any reason
whatsoever, and that the Certificates, upon due authentication thereof by the
Trustee pursuant to this Agreement, are and shall be deemed fully paid.

      SECTION 10.11. Third Party Rights.

      The NIM Insurer shall be deemed a third-party beneficiary of this
Agreement to the same extent as if it were a party hereto, and shall have the
right to enforce the provisions of this Agreement.

      SECTION 10.12. Additional Rights of the NIM Insurer.

thereto shall furnish to the NIM Insurer a copy of any notice, direction,
demand, opinion, schedule, list, certificate, report, statement, filing,
information, data or other communication provided by it or on its behalf to any
other Person pursuant to this Agreement at the same time, in the same form and
in the same manner as such communication is so provided and shall address or
cause such communication to be addressed to the NIM Insurer in addition to any
other addressee thereof. The Servicer shall cause the NIM Insurer to be an
addressee of any report furnished pursuant to this Agreement.

      (b) Wherever in this Agreement there shall be a requirement that there be
no downgrade, reduction, withdrawal or qualification of or other effect on the
rating of any Class of Certificates by any Rating Agency as of any date, there
also shall be deemed to be a requirement that there be no such effect on any
class of notes issued pursuant to the Indenture and guaranteed by the NIM
Insurer as of such date. In addition, unless there exists a continuance of any
failure by the NIM Insurer to make a required payment under the policy insuring
the NIM Notes (such event, a "NIM Insurer Default"), wherever in this Agreement
there shall be a requirement that any Person or any communication, object or
other matter be acceptable or satisfactory to or otherwise receive the consent
or other approval of any other Person (whether as a condition to the eligibility
of such Person to act in any capacity, as a condition to any circumstance or
state of affairs related to such matter, or otherwise), there also shall be
deemed to be a requirement that such Person or matter be approved in writing by
the NIM Insurer, which approval shall not be unreasonably withheld or delayed.

      SECTION 10.13. Reserved.

      SECTION 10.14. Assignment; Sales; Advance Facilities.

      (a) The Servicer is hereby authorized to enter into a financing or other
facility (any such arrangement, an "Advance Facility"), the documentation for
which complies with Section 10.14(e) below, under which (1) the Servicer assigns
or pledges its rights under this Agreement to be reimbursed for any or all
Advances and/or Servicing Advances to (i) a Person, which may be a
special-purpose bankruptcy-remote entity (an "SPV"), (ii) a Person, which may
simultaneously assign or pledge such rights to an SPV or (iii) a lender (a
"Lender"), which, in the case of any Person or SPV of the type described in
either of the preceding clauses (i) or (ii), may directly or through other
assignees and/or pledgees, assign or pledge such rights to a Person, which may
include a trustee acting on behalf of holders of debt instruments (any such
Person or any such Lender, an "Advance Financing Person"), and/or (2) an Advance
Financing

                                      117
<PAGE>

Person agrees to fund all the Advances and/or Servicing Advances required to be
made by the Servicer pursuant to this Agreement. No consent of the Trustee,
Certificateholders or any other party shall be required before the Servicer may
enter into an Advance Facility nor shall the Trustee or the Certificateholders
be a third party beneficiary of any obligation of an Advance Financing Person to
the Servicer. Notwithstanding the existence of any Advance Facility under which
an Advance Financing Person agrees to fund Advances and/or Servicing Advances,
(A) the Servicer (i) shall remain obligated pursuant to this Agreement to make
Advances and/or Servicing Advances pursuant to and as required by this Agreement
and (ii) shall not be relieved of such obligations by virtue of such Advance
Facility and (B) neither the Advance Financing Person nor any Servicer's
Assignee (as hereinafter defined) shall have any right to proceed against or
otherwise contact any Mortgagor for the purpose of collecting any payment that
may be due with respect to any related Mortgage Loan or enforcing any covenant
of such Mortgagor under the related Mortgage Loan documents.

      (b) If the Servicer enters into an Advance Facility, the Servicer and the
related Advance Financing Person shall deliver to the Trustee at the address set
forth in Section 10.05 hereof a written notice (an "Advance Facility Notice"),
stating (a) the identity of the Advance Financing Person and (b) the identity of
the Person (the "Servicer's Assignee") that will, subject to Section 10.14(c)
hereof, have the right to make withdrawals from the Collection Account pursuant
to Section 3.08(a) hereof to reimburse previously unreimbursed Advances and/or
Servicing Advances ("Advance Reimbursement Amounts"). Advance Reimbursement
Amounts (i) shall consist solely of amounts in respect of Advances and/or
Servicing Advances for which the Servicer would be permitted to reimburse itself
in accordance with Section 3.08 hereof, assuming the Servicer had made the
related Advance(s) and/or Servicing Advance(s) and (ii) shall not consist of
amounts payable to a successor servicer in accordance with Section 3.05 hereof
to the extent permitted under Section 10.14(e) below.

      (c) Notwithstanding the existence of an Advance Facility, the Servicer, on
behalf of the Advance Financing Person and the Servicer's Assignee, shall be
entitled to receive reimbursements of Advances and/or Servicing Advances in
accordance with Section 4.01 hereof, which entitlement may be terminated by the
Advance Financing Person pursuant to a written notice to the Trustee in the
manner set forth in Section 10.05 hereof. Upon receipt of such written notice,
the Servicer shall no longer be entitled to receive reimbursement for any
Advance Reimbursement Amounts and the Servicer's Assignee shall immediately have
the right to receive from the Collection Account all Advance Reimbursement
Amounts. Notwithstanding the foregoing, and for the avoidance of doubt, (i) the
Servicer and/or the Servicer's Assignee shall only be entitled to reimbursement
of Advance Reimbursement Amounts hereunder from withdrawals from the Collection
Account pursuant to Section 4.01 of this Agreement and shall not otherwise be
entitled to make withdrawals or receive amounts that shall be deposited in the
Distribution Account pursuant to Section 4.01 hereof, and (ii) none of the
Trustee or the Certificateholders shall have any right to, or otherwise be
entitled to, receive any Advance Reimbursement Amounts to which the Servicer or
Servicer's Assignee, as applicable, shall be entitled pursuant to Section 4.01
hereof. An Advance Facility may be terminated by the joint written direction of
the Servicer and the related Advance Financing Person. Written notice of such
termination shall be delivered to the Trustee in the manner set forth in Section
10.05 hereof. None of the Depositor or the Trustee shall, as a result of the
existence of any Advance Facility, have any additional duty or liability with
respect to the calculation or payment of any Advance Reimbursement Amount, nor,
as a result of the existence of any Advance Facility, shall the Depositor or the
Trustee have any additional responsibility to track or monitor the
administration of the Advance Facility or the payment of Advance Reimbursement
Amounts to the Servicer's Assignee. The Servicer shall indemnify the Depositor,
the Trustee, any successor servicer and the Trust Fund for any claim, loss,
liability or damage resulting from any claim by the related Advance Financing
Person, except to the extent that such claim, loss, liability or damage resulted
from or arose out of negligence, recklessness or willful misconduct on the part
of the Depositor, the Trustee or any successor servicer, as the case may be, or
failure by the successor servicer or the Trustee, as the case may be, to remit
funds as

                                      118
<PAGE>

required by this Agreement or the commission of an act or omission to act by the
successor servicer or the Trustee, as the case may be, and the passage of any
applicable cure or grace period, such that an Event of Default under this
Agreement occurs or such entity is subject to termination for cause under this
Agreement. The Servicer shall maintain and provide to any successor servicer
and, upon request, the Trustee a detailed accounting on a loan-by-loan basis as
to amounts advanced by, pledged or assigned to, and reimbursed to any Advance
Financing Person. The successor servicer shall be entitled to rely on any such
information provided by the predecessor Servicer, and the successor servicer
shall not be liable for any errors in such information.

      (d) [RESERVED]

      (e) As between a predecessor Servicer and its Advance Financing Person, on
the one hand, and a successor servicer and its Advance Financing Person, if any,
on the other hand, Advance Reimbursement Amounts on a loan-by-loan basis with
respect to each Mortgage Loan as to which an Advance and/or Servicing Advance
shall have been made and be outstanding shall be allocated on a "first-in, first
out" basis. In the event the Servicer's Assignee shall have received some or all
of an Advance Reimbursement Amount related to Advances and/or Servicing Advances
that were made by a Person other than such predecessor Servicer or its related
Advance Financing Person in error, then such Servicer's Assignee shall be
required to remit any portion of such Advance Reimbursement Amount to each
Person entitled to such portion of such Advance Reimbursement Amount. Without
limiting the generality of the foregoing, the Servicer shall remain entitled to
be reimbursed by the Advance Financing Person for all Advances and/or Servicing
Advances funded by the Servicer to the extent the related Advance Reimbursement
Amounts have not been assigned or pledged to such Advance Financing Person or
Servicer's Assignee.

      (f) For purposes of any Officer's Certificate of the Servicer made
pursuant to Section 4.01, any Non-Recoverable Advance or Non-Recoverable
Servicing Advance referred to therein may have been made by such Servicer or any
predecessor Servicer. In making its determination that any Advance or Servicing
Advance theretofore made has become a Non-Recoverable Advance or Non-Recoverable
Servicing Advance, the Servicer shall apply the same criteria in making such
determination regardless of whether such Advance or Servicing Advance shall have
been made by the Servicer or any predecessor Servicer.

      (g) Any amendment to this Section 10.14 or to any other provision of this
Agreement that may be necessary or appropriate to effect the terms of an Advance
Facility as described generally in this Section 10.14, including amendments to
add provisions relating to a successor servicer, may be entered into by the
Trustee, the Depositor and the Servicer without the consent of any
Certificateholder, provided such amendment complies with Section 10.01 hereof.
All reasonable costs and expenses (including attorneys' fees) of each party
hereto of any such amendment shall be borne solely by the Servicer. The parties
hereto hereby acknowledge and agree that: (a) the Advances and/or Servicing
Advances financed by and/or pledged to an Advance Financing Person under any
Advance Facility are obligations owed to the Servicer payable only from the cash
flows and proceeds received under this Agreement for reimbursement of Advances
and/or Servicing Advances only to the extent provided herein, and the Trustee
and the Trust are not, as a result of the existence of any Advance Facility,
obligated or liable to repay any Advances and/or Servicing Advances financed by
the Advance Financing Person; (b) the Servicer will be responsible for remitting
to the Advance Financing Person the applicable amounts collected by it as
reimbursement for Advances and/or Servicing Advances funded by the Advance
Financing Person, subject to the provisions of this Agreement; and (c) the
Trustee shall not have any responsibility to track or monitor the administration
of the financing arrangement between the Servicer and any Advance Financing
Person.

Class R Certificate only (a) to a transferee that (i) is not a disqualified

(2)   the Transferee's Employer Identification number is , _____________________

(3)   the Transferee is not a "disqualified organization" (as defined below),

      Residential Finance Trust, Mortgage Loan Asset-Backed Certificates, Series
      2004-BC3, Class R Certificate on behalf of a disqualified organization or
      any other entity,

(4)   unless Merrill Lynch Mortgage Investors, Inc.("MLMI") has consented to the
      transfer to the Transferee by executing the form of Consent affixed as
      Appendix B to the Transferee's Letter to which this Certificate is affixed
      as Appendix A, the Transferee is a "U.S. person" (as defined below),

(5)   that no purpose of the transfer is to avoid or impede the assessment or
      collection of tax,

(6)   the Transferee has historically paid its debts as they became due,

(7)   the Transferee intends, and believes that it will be able, to continue to

      generated by the Class R Certificate,

(9)   the Transferee intends to pay any taxes associated with holding the Class
      R Certificate as they become due,

(10)  the Transferee consents to any amendment of the Pooling and Servicing

      organization, and

(11)  IF BRACKETED, THE FOLLOWING CERTIFICATIONS ARE INAPPLICABLE [the transfer
      is not a direct or indirect transfer of the Class R Certificate to a
      foreign permanent establishment or fixed base (within the meaning of an
      applicable income tax treaty) of the Transferee, and as to each of the
      residual interests represented by the Class R Certificate, the present
      value of the anticipated tax liabilities associated with holding such
      residual interest does not exceed the sum of:

      (A)   the present value of any consideration given to the Transferee to
            acquire such residual interest;

      (B)   the present value of the expected future distributions on such
            residual interest; and

      For purposes of this declaration, (i) the Transferee is assumed to pay tax
      at a rate equal to the highest rate of tax specified in Section I l(b)(1)
      of the Code, but the tax rate specified in Section 55(b)(1)(B) of the Code
      may be used in lieu of the highest rate specified in Section 11(b)(1) of
      the Code if the Transferee has been subject to the alternative minimum tax
      under Section 55 of the Code in the preceding two years and will compute
      its taxable income in the current taxable year using the alternative
      minimum tax rate, and (ii) present values are computed using a discount
      rate equal to the Federal short-term rate prescribed by Section 1274(d) of
      the Code for the month of the transfer and the compounding period used by
      the Transferee;]

[(11) (A)   at the time of the transfer, and at the close of each of the
            Transferee's two fiscal years preceding the Transferee's fiscal year
            of transfer, the Transferee's gross assets for financial reporting
            purposes exceed $100 million and its net assets for financial
            reporting purposes exceed $10 million; and

      (B)   the Transferee is an eligible corporation as defined in Treasury

            any subsequent transfer of the Class R Certificate will be to
            another eligible corporation in a transaction that satisfies
            Treasury regulation Sections 1.860E-1(c)(4)(i), 1.860E-1(c)(4)(ii),
            1.860E-1(c)(4)(iii) and 1.860E1(c)(5) and such transfer will not be
            a direct or indirect transfer to a foreign permanent establishment
            (within the meaning of an applicable income tax treaty) of a
            domestic corporation.

For purposes of this declaration, the gross and net assets of the Transferee do
not include any obligation of any related person as defined in Treasury
regulation Section 1.860E-1(c)(6)(ii) or any other asset if a principal purpose
for holding or acquiring the other asset is to permit the Transferee to make
this declaration or to satisfy the requirements of Treasury regulation Section
1.860E-1(c)(5)(i).]

(12) The Transferee will not cause income from the Class R Certificate to be
attributable to a foreign permanent establishment or fixed base (within the
meaning of an applicable income tax treaty) of the Transferee or another U.S.
taxpayer.

            ______________________(the "Transferor") has reviewed the attached
affidavit of _______________________(the "Transferee"), and has no actual
knowledge that such affidavit is not true, and has no reason to believe that the
Transferee has the intention to impede the assessment or collection of any
federal, state or local taxes legally required to be paid with respect to the
Class R Certificate referred to in the attached affidavit. In addition, the
Transferor has conducted a reasonable investigation at the time of the transfer
and found that the Transferee had historically paid its debts as they came due
and found no significant evidence to indicate that the Transferee will not
continue to pay its debts as they become due.

set forth in the Pooling and Servicing Agreement.

      For good and valuable consideration, the receipt and sufficiency of which

covenants with, the Depositor and the Trustee that:

      1. The Purchaser understands that (a) the Certificates have not been

"Securities Act"), or the securities laws of any state, (b) neither the
Depositor nor the Trustee is required, and neither of them intends, to so
register or qualify the Certificates, (c) the Certificates cannot be resold
unless (1) they are registered and qualified under the Securities Act and the
applicable state securities laws or (ii) an exemption from registration and
qualification is available and (d) the Pooling and Servicing Agreement contains
restrictions regarding the transfer of the Certificates.

      2. The Certificates will bear a legend to the following effect:

      THIS CERTIFICATE HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,
AS AMENDED (THE "ACT"), THE INVESTMENT COMPANY ACT OF 1940, AS AMENDED (THE
"1940 ACT") OR ANY STATE SECURITIES OR "BLUE SKY" LAWS, AND MAY NOT, DIRECTLY OR
INDIRECTLY, BE SOLD OR OTHERWISE TRANSFERRED, OR OFFERED FOR SALE, UNLESS SUCH
TRANSFER IS NOT SUBJECT TO REGISTRATION UNDER THE ACT, THE 1940 ACT AND ANY

<PAGE>

SHALL HAVE RECEIVED, IN FORM AND SUBSTANCE SATISFACTORY TO THE SERVICER (A) AN
INVESTMENT LETTER FROM THE PROSPECTIVE INVESTOR; AND (B) REPRESENTATIONS FROM

TRANSFEREE IS NOT AN EMPLOYEE BENEFIT PLAN SUBJECT TO TITLE I OF ERISA, A PLAN
SUBJECT TO SECTION 4975 OF THE CODE, A PLAN SUBJECT TO ANY STATE, LOCAL,
FEDERAL, NON-U.S. OR OTHER LAW SUBSTANTIVELY SIMILAR TO THE FOREGOING PROVISIONS
OF ERISA OR THE CODE ("SIMILAR LAW"), OR A PERSON DIRECTLY OR INDIRECTLY ACTING
ON BEHALF OF OR USING ANY ASSETS OF ANY SUCH PLAN, OR (II) IF THE CERTIFICATE
HAS BEEN THE SUBJECT OF AN ERISA-QUALIFYING UNDERWRITING, THAT SUCH TRANSFEREE
IS AN INSURANCE COMPANY THAT IS ACQUIRING THE CERTIFICATE WITH ASSETS OF AN
"INSURANCE COMPANY GENERAL ACCOUNT," AS DEFINED IN SECTION V(E) OF PROHIBITED
TRANSACTION CLASS EXEMPTION ("PTCE") 95-60, AND THE ACQUISITION AND HOLDING OF

NIM INSURER SHALL BE ENTITLED TO RELY, TO THE EFFECT THAT THE ACQUISITION AND
HOLDING OF THE CERTIFICATE WILL NOT CONSTITUTE OR RESULT IN A NONEXEMPT
PROHIBITED TRANSACTION UNDER ERISA OR THE CODE, OR A VIOLATION OF SIMILAR LAW,

ADDITION TO THOSE EXPRESSLY UNDERTAKEN IN THE POOLING AND SERVICING AGREEMENT,
WHICH OPINION OF COUNSEL SHALL NOT BE AN EXPENSE OF THE TRUSTEE OR THE NIM
INSURER. IF THE CERTIFICATE IS NOT A DEFINITIVE CERTIFICATE, THE TRANSFEREE IS
DEEMED TO HAVE MADE THE REPRESENTATION IN (A)(I) OR (A)(II) ABOVE.

      3. The Purchaser is acquiring the Transferred Certificates for its own
account [FOR INVESTMENT ONLY]**/ and not with a view to or for sale or other
transfer in connection with any distribution of the Transferred Certificates in

      4. The Purchaser (a) is a substantial, sophisticated institutional

an investment and (c) is an "accredited investor" within the meaning of Rule 501
(a) promulgated pursuant to the Securities Act.

disposition or other transfer of any Certificate, any interest in any
Certificate or any other similar security from any person in any manner, (c)

would constitute a distribution of any Certificate under the Securities Act or
the Investment Company Act of 1940, as amended (the "1940 Act"), that would
render the disposition of any Certificate a violation of Section 5 of the
Securities Act or any state securities law, or that would require registration
or qualification pursuant thereto. Neither the Purchaser nor anyone acting on
its behalf has offered the Certificates for sale or made any general
solicitation by means of general advertising or in any other manner with respect
to the Certificates. The Purchaser will not sell or otherwise transfer any of
the Certificates, except in compliance with the provisions of the Pooling and
Servicing Agreement.

or (B) solely in the event the Certificate is a Definitive Certificate, herewith
delivers an Opinion of Counsel satisfactory to the Trustee, and upon which the
Trustee and NIM Insurer shall be entitled to rely, to the effect that the
acquisition and holding of the Certificate will not constitute or result in a
nonexempt prohibited transaction under ERISA or the Code, or a violation of
Similar Law, and will not subject the Trustee or the NIM Insurer to any
obligation in addition to those expressly undertaken in the Pooling and
Servicing Agreement, which Opinion of Counsel shall not be an expense of the
Trustee or the NIM Insurer.

      7. Prior to the sale or transfer by the Purchaser of any of the
Certificates, the Purchaser will obtain from any subsequent purchaser
substantially the same certifications, representations, warranties and covenants
contained in the foregoing paragraphs and in this letter or a letter
substantially in the form of Exhibit [H] to the Pooling and Servicing Agreement.

                                       G-3

      The following sets forth the auction procedures to be followed in
connection with Pooling and Servicing Agreement (the "Agreement") among Merrill
Lynch Mortgage Investors, Inc., JPMorgan Chase Bank, as trustee and Litton Loan

otherwise defined shall have the meanings described thereto in the Agreement.

1.    Upon notice to the Servicer by the Trustee of the initiation of the
      auction, the Servicer will initiate the general auction procedures
      consisting of the following: (i) prepare a general solicitation package
      along with a confidentiality agreement; (ii) derive a list of a minimum of
      three (3) bidders, each of whom shall be a nationally recognized
      participant in mortgage finance, (iii) initiate contact with all bidders,
      (iv) send a confidentiality agreement to all bidders, and (v) upon receipt
      of a signed confidentiality agreement, send bid solicitation package to
      all bidders.

2.    The general solicitation package will include (i) the Agreement; (ii) a
      copy of all monthly trustee reports or electronic access thereto; (iii) a
      form of a Mortgage Loan Purchase Agreement acceptable to the Trustee and
      Servicer (the Mortgage Loans and other property included in the Trust Fund
      will be offered and sold on an "as is, where is basis, without any
      representation or warranty, expressed or implied, of any kind and without
      recourse to, or guaranty by, the Trustee); (iv) a description of the
      minimum price as set forth in the Agreement; (v) a formal bidsheet as
      determined by the Servicer and accepted by the Trustee; (vi) a detailed
      timetable (which shall include, but not be limited to, the provisions and
      dates preliminary bids, due diligence and final bids); and (vii) a data
      tape of the Mortgage Loans as of the related Remittance Period reflecting
      substantially the same data attributes used in the Prospectus Supplement
      dated October 25, 2004.

3.    A detailed timetable will be determined approximately ten (10) days prior
      to each auction sale and shall be determined by the Servicer with the
      consent of the Trustee, which consent shall not be unreasonably withheld,
      within reasonable market conditions at the time of the auction sale.

4.    All bids will be submitted directly to the Trustee. Upon acceptance of a
      bid which meets or exceeds the conditions set forth in Section 9.01, the
      Trustee will distribute the proceeds from the auction to the holders of
      the Certificates on the next succeeding Distribution Date as set forth in
      the Agreement. In the event the Trustee receives two (2) or more bids from
      bidders above the Auction Termination Price and at equal bids (a "Tie
      Event"), the Trustee shall notify such bidders to resubmit a bid to break
      the Tie Event.

5.    Upon determination that the minimum price was not met, the Trustee shall
      cancel such auction sale and notify the Servicer, Depositor and NIM
      Insurer immediately.

6.    The Trustee, the Servicer and the Depositor may mutually agree to revise
      or supplement these provisions as necessary, provided that the purchase
      price is at all times required to be at least the Auction Termination
      Price.
