                         CONVEYANCE OF MORTGAGE LOANS

      Section 2.01. Creation and Declaration of Trust Estate; Conveyance of

      (a) Mortgage Loans. As of the Closing Date, in consideration of the
Issuer's delivery of the Notes and the Ownership Certificate to the Depositor
or its designee, and concurrently with the execution and delivery of this
Agreement, the Depositor does hereby transfer, assign, set over, deposit with
and otherwise convey to the Issuer, without recourse, subject to Section 3.01,
in trust, all the right, title and interest of the Depositor in and to the
Mortgage Loans. Such conveyance includes, without limitation, the right to all

Loans on and after the Cut-off Date (other than payments of principal and
interest due on or before such date), and all such payments due after such
date but received prior to such date and intended by the related Mortgagors to

<PAGE>

      Concurrently with the execution and delivery of this Agreement, the
Depositor does hereby assign to the Issuer all of its rights and interest
under the Mortgage Loan Purchase Agreement but without delegation of any of
its obligations thereunder. The Issuer hereby accepts such assignment, and
shall be entitled to exercise all the rights of the Depositor under the
Mortgage Loan Purchase Agreement as if, for such purpose, it were the
Depositor. Upon the issuance of the Notes, ownership in the Trust Estate shall
be vested in the Issuer, subject to the lien created by the Indenture in favor
of the Indenture Trustee, for the benefit of the Noteholders. The foregoing
sale, transfer, assignment, set-over, deposit and conveyance does not and is
not intended to result in creation or assumption by the Indenture 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
except as specifically set forth herein.

      The Depositor further agrees to cause ________________________ to assign
all of its right, title and interest in and to the interest rate corridor
transaction evidenced by each Confirmation to the Issuer, and all such right,
title and interest shall be deemed to have been assigned by
________________________ to the Depositor and by the Depositor to the Issuer.

      (b) Subject to the execution and delivery of the related Subsequent
Transfer Agreement as provided by Section 2.01(d) and the terms and conditions
of this Agreement, the Depositor sells, transfers, assigns, sets over and
otherwise conveys to the Issuer, without recourse, on each Subsequent Transfer
Date, all the right, title and interest of the Depositor in and to the related
Subsequent Mortgage Loans, including all interest and principal received and
receivable by the Depositor on or with respect to such Subsequent Mortgage
Loans after the related Subsequent Cut-off Date (to the extent not applied in
computing the Cut-off Date Principal Balance thereof) or deposited into the
Collection Account by the Master Servicer on behalf of such Seller as part of
any related Subsequent Deposit as provided in this Agreement, other than
principal due on such Subsequent Mortgage Loans on or prior to the related
Subsequent Cut-off Date and interest accruing prior to the related Subsequent
Cut-off Date.

      Immediately upon the conveyance of the Subsequent Mortgage Loans
referred to in the preceding paragraph, the Depositor sells, transfers,
assigns, sets over and otherwise conveys to the Trustee for benefit of the
Noteholders and the [Class AF-5B] Insurer, without recourse, all right title
and interest in the Subsequent Mortgage Loans.

      (c) The Depositor has entered into this Agreement in consideration for
the purchase of the Mortgage Loans by the Issuer and has agreed to take the
actions specified herein.

      (d) On any Business Day during the Funding Period designated by the

complete, execute and deliver a Subsequent Transfer Agreement. After the
execution and delivery of such Subsequent Transfer Agreement, on the
Subsequent Transfer Date, the Trust Administrator shall set aside in the
Pre-Funding Account an amount equal to the related Subsequent Transfer Date
Purchase Amount.

      (e) The transfer of Subsequent Mortgage Loans on the Subsequent Transfer
Date is subject to the satisfaction of each of the following conditions:

                                      50
<PAGE>

            (1) the Trust Administrator and the Underwriters will be provided
      Opinions of Counsel addressed to the Rating Agencies as with respect to
      the sale of the Subsequent Mortgage Loans conveyed on such Subsequent
      Transfer Date (such opinions being substantially similar to the opinions
      delivered on the Closing Date to the Rating Agencies with respect to the
      sale of the Initial Mortgage Loans on the Closing Date), to be delivered
      as provided in Section 2.01(f);

            (2) the execution and delivery of such Subsequent Transfer
      Agreement or conveyance of the related Subsequent Mortgage Loans does
      not result in a reduction or withdrawal of the any ratings assigned to
      the Notes by the Ratings Agencies (without regard to the [Class AF-5B]
      Policy, in the case of the [Class AF-5B] Notes);

            (3) the Depositor shall deliver to the Trust Administrator an
      Officer's Certificate confirming the satisfaction of each of the
      conditions set forth in this Section 2.01(e) required to be satisfied by
      such Subsequent Transfer Date;

            (4) each Subsequent Mortgage Loan conveyed on such Subsequent
      Transfer Date satisfies the representations and warranties applicable to
      it under this Agreement, provided, however, that with respect to a
      breach of a representation and warranty with respect to a Subsequent
      Mortgage Loan set forth in this clause (4), the obligation under this
      Agreement of the applicable Seller, to cure, repurchase or replace such
      Subsequent Mortgage Loan shall constitute the sole remedy against such
      Seller respecting such breach available to Noteholders, the Depositor or
      the Trust Administrator;

            (5) the Subsequent Mortgage Loans conveyed on such Subsequent
      Transfer Date were selected in a manner reasonably believed not to be
      adverse to the interests of the Noteholders;

            (6) no Subsequent Mortgage Loan conveyed on such Subsequent
      Transfer Date was [30] or more days delinquent;

            (7) following the conveyance of the Subsequent Mortgage Loans on
      such Subsequent Transfer Date, the characteristics of each Pool will not
      vary by more than the amount specified below (other than the percentage
      of Mortgage Loans secured by Mortgaged Properties located in the State
      of California, which will not exceed [50]% of the Mortgage Pool and the
      percentage of mortgage loans in the Credit Grade Categories of "C" or
      below, which will not exceed [10]% of the Mortgage Loans in each Pool)
      from the characteristics listed below; provided that for the purpose of
      making such calculations, the characteristics for any Initial Mortgage
      Loan made will be taken as of the Initial Cut-off Date and the
      characteristics for any Subsequent Mortgage Loans will be taken as of
      the Subsequent Cut-off Date; and

            (8) none of the Sellers or the Depositor is insolvent and neither
      of the Sellers nor the Depositor will be rendered insolvent by the

      (g) In connection with such transfer and assignment, the Depositor does
hereby deliver to, and deposit with, or cause to be delivered to and deposited

      recording but has not been returned from the applicable public recording
      office, has been lost or is not otherwise available, a copy of such

      abstract of title;

            (vii) the original or copies of each assumption, modification,
      written assurance or substitution agreement, if any, or as to any such
      agreement which cannot be delivered prior to the Closing Date because of
      a delay caused by the public recording office where such assumption,
      modification or substitution agreement has been delivered for
      recordation, a photocopy of such assumption, modification or
      substitution agreement, pending delivery of the original thereof,

to the Indenture Trustee, for the benefit of the Noteholders, of the Mortgage
Notes and the Mortgages.

      (h) Assignments of Mortgage with respect to each Non-MERS Mortgage Loan
shall be recorded; provided, however, that such Assignments need not be
recorded if, on or prior to the Closing Date, the Seller delivers an Opinion
of Counsel (which must be Independent counsel) acceptable to the Rating
Agencies, to the effect that recording in such states is not required to
protect the Indenture Trustee's interest in the related Non-MERS Mortgage
Loans.

      (i) In instances where a Title Insurance Policy is required to be
delivered to the Indenture Trustee or the Custodian on behalf of the Indenture
Trustee under clause (b)(vi) above and is not so delivered, the Seller will
provide a copy of such Title Insurance Policy to the Indenture Trustee, or to
the Custodian on behalf of the Indenture Trustee, as promptly as practicable
after the execution and delivery hereof, but in any case within [180] days of

delivering the above documents, herewith delivers to the Indenture Trustee, or
to the Custodian on behalf of the Indenture Trustee, an Officer's Certificate
which shall include a statement to the effect that all amounts received in
connection with such prepayment that are required to be deposited in the
Collection Account pursuant to Section 5.07 have been so deposited. All

      Section 2.02. Acceptance of Trust Estate; Review of Documentation.

      (a) Subject to the provisions of Section 2.01, the Issuer acknowledges
receipt of the assets transferred by the Depositor of the assets included in
the Trust Estate and has directed that the documents referred to in Section
2.01 and all other assets included in the definition of "Trust Estate" be
delivered to the Indenture Trustee (or the Custodian) on its behalf.

      The Indenture Trustee, by execution and delivery hereof, acknowledges
receipt by it or by the applicable Custodian on its behalf of the Mortgage
Files pertaining to the Mortgage Loans listed on the Mortgage Loan Schedule,
subject to review thereof by the Indenture Trustee, or by the Custodian on
behalf of the Indenture Trustee, under this Section 2.02. The Indenture
Trustee, or the Custodian on behalf of the Indenture Trustee, will execute and
deliver to the Depositor, the Master Servicer, the Servicer (and the Indenture
Trustee if delivered by the Custodian) on the Closing Date an Initial
Certification in the form annexed hereto as Exhibit A-1 (or in the form
annexed to the Custodial Agreement as Exhibit B-1, as applicable).

      (b) Within [45] days after the Closing Date with respect to the Initial
Mortgage Loans and within [90] days after the Subsequent Transfer Date with
respect to the Subsequent Mortgage Loans, the Indenture Trustee or the
Custodian on behalf of the Indenture Trustee, will, for the benefit of
Noteholders, review each Mortgage File to ascertain that all required
documents set forth in Section 2.01 have been received and appear on their
face to contain the requisite signatures by or on behalf of the respective
parties thereto, and shall deliver to the Depositor, the Master Servicer and
the Servicer (and the Indenture Trustee if delivered by the Custodian) an
Interim Certification in the form annexed hereto as Exhibit A-2 (or in the
form annexed to the Custodial Agreement as Exhibit B-2, as applicable) to the
effect that, as to each Mortgage Loan listed in the Mortgage Loan Schedule
(other than any Mortgage Loan prepaid in full or any specifically identified
in such certification as not covered by such certification), (i) all of the
applicable documents specified in Section 2.01(b) are in its possession and
(ii) such documents have been reviewed by it and appear to relate to such
Mortgage Loan. The Indenture Trustee, or the Custodian on behalf of the
Indenture Trustee, shall determine whether such documents are executed and
endorsed, but shall be under no duty or obligation to inspect, review or
examine any such documents, instruments, certificates or other papers to
determine that the same are valid, binding, legally effective, properly
endorsed, genuine, enforceable or appropriate for the represented purpose or
that they have actually been recorded or are in recordable form or that they
are other than what they purport to be on their face. Neither the Indenture
Trustee nor the Custodian shall have any responsibility for verifying the
genuineness or the legal effectiveness of or authority for any signatures of
or on behalf of any party or endorser or for the perfection or priority of any
document.

      (c) If in the course of the review described in paragraph (b) above the
Indenture Trustee or the Custodian discovers any document or documents
constituting a part of a Mortgage File that is missing, does not appear
regular on its face (i.e., is mutilated, damaged, defaced, torn or otherwise
physically altered) or appears to be unrelated to the Mortgage Loans
identified in the Mortgage Loan Schedule, as applicable (each, a "Material
Defect"), the Indenture Trustee, or the Custodian on behalf of the Indenture
Trustee, discovering such Material Defect shall identify the Mortgage Loan to
which such Material Defect relates in the Interim Certification delivered to
the Depositor and the Master Servicer. Within [90] days of its receipt of such
notice, the Seller

                                      55
<PAGE>

shall be required to cure such Material Defect (and, in such event, the Seller
shall provide the Indenture Trustee with an Officer's Certificate confirming
that such cure has been effected). If the Seller does not so cure such
Material Defect, if a loss has been incurred with respect to such Mortgage
Loan that would, if such Mortgage Loan were not purchased from the Trust
Estate, constitute a Realized Loss, and such loss is attributable to the
failure of the Seller to cure such Material Defect, the Seller shall
repurchase the related Mortgage Loan from the Trust Estate at the Purchase
Price. A loss shall be deemed to be attributable to the failure of the Seller
to cure a Material Defect if, as determined by the Seller acting in good
faith, absent such Material Defect, such loss would not have been incurred.
The Seller may, in lieu of repurchasing a Mortgage Loan pursuant to this
Section 2.02, substitute for such Mortgage Loan a Qualifying Substitute
Mortgage Loan subject to the provisions of Section 3.03. The failure of the
Indenture Trustee or the Custodian to deliver the Interim Certification within
[45] days after the Closing Date or [90] days after the Subsequent transfer
Date shall not affect or relieve the Seller of its obligation to repurchase
any Mortgage Loan pursuant to this Section 2.02 or any other Section of this
Agreement requiring the repurchase of Mortgage Loans from the Trust Estate.

      (d) Within [180] days following the Closing Date with respect to the
Initial Mortgage Loans and within [180] days following the Subsequent Transfer
Date with respect to the Subsequent Mortgage Loans, the Indenture Trustee, or
the Custodian, shall deliver to the Depositor, the Master Servicer and the
Servicer (and the Indenture Trustee if delivered by the Custodian) a Final
Certification substantially in the form attached as Exhibit A-3 (or in the
form annexed to the Custodial Agreement as Exhibit B-3, as applicable)
evidencing the completeness of the Mortgage Files in its possession or
control, with any exceptions noted thereto.

      (e) Nothing in this Agreement shall be construed to constitute an
assumption by the Trust Estate, the Indenture Trustee, the Custodian or the
Noteholders of any unsatisfied duty, claim or other liability on any Mortgage
Loan or to any Mortgagor.

      (f) Notwithstanding anything to the contrary contained herein, each of
the parties hereto acknowledges that the Custodian shall perform the
applicable review of the Mortgage Loans and respective certifications thereof
as provided in the Custodial Agreement.

      (g) Upon execution of this Agreement, the Depositor hereby delivers to
the Indenture Trustee and the Indenture Trustee acknowledges a receipt of the
Mortgage Loan Purchase Agreement.

      (h) For purposes of the determinations required to be made by the
Indenture Trustee or the Custodian pursuant to paragraphs (a) through (d) of
this Section 2.02, the Indenture Trustee or the Custodian, as applicable,
shall be entitled to conclusively rely upon the diskette, tape or other
electronic media provided by or on behalf of the Seller with respect to the
Mortgage Loans as to whether (i) any guarantee was executed in connection with
any Mortgage Loan, (ii) any assumption, modification or substitution agreement
was executed in connection with any Mortgage Loan, (iii) primary mortgage
guaranty insurance is required with respect to any Mortgage Loan or (iv) any
security agreement or equivalent instrument was executed in connection with
any Mortgage Loan.

      Section 2.03. Grant Clause.

                                      56
<PAGE>

      (a) It is intended that the conveyance by the Depositor to the Issuer of
the Mortgage Loans, as provided for in Section 2.01, be construed as a sale by
the Depositor to the Issuer of the Mortgage Loans and other assets in the
Trust Estate for the benefit of the Noteholders. Further, it is not intended
that any such conveyance be deemed to be a pledge of the Mortgage Loans by the
Depositor to the Issuer to secure a debt or other obligation of the Depositor.
However, in the event that the Mortgage Loans are held to be property of the
Depositor or if for any reason this Agreement is held or deemed to create a
security interest in the Mortgage Loans and other assets in the Trust Estate,
then it is intended that (a) this Agreement shall also be deemed to be a
security agreement within the meaning of Articles 8 and 9 of the New York UCC
(or the Relevant UCC if not the New York UCC); (b) the conveyances provided
for in Section 2.01 shall be deemed to be (1) a grant by the Depositor to the
Issuer of a security interest in all of the Depositor's right (including the
power to convey title thereto), title and interest, whether now owned or
hereafter acquired, in and to (A) the Mortgage Loans, including the Mortgage
Notes, the Mortgages, any related insurance policies and all other documents
in the related Mortgage Files, (B) all amounts payable pursuant to the
Mortgage Loans in accordance with the terms thereof and (C) any and all
general intangibles consisting of, arising from or relating to any of the
foregoing, and all proceeds of the conversion, voluntary or involuntary, of
the foregoing into cash, instruments, securities or other property, including
without limitation all Liquidation Proceeds, all Insurance Proceeds, all
amounts from time to time held or invested in the Collection Account, whether
in the form of cash, instruments, securities or other property and (2) an
assignment by the Depositor to the Issuer of any security interest in any and
all of the Depositor's right (including the power to convey title thereto),
title and interest, whether now owned or hereafter acquired, in and to the
property described in the foregoing clauses (1)(A) through (C); (c) the
possession by the Indenture Trustee or any other agent of the Issuer of
Mortgage Notes, and such other items of property as constitute instruments,
money, negotiable documents or chattel paper shall be deemed to be "possession
by the secured party," or possession by a purchaser or a person designated by
such secured party, for purposes of perfecting the security interest pursuant
to the New York UCC and any other Relevant UCC (including, without limitation,
Section 9-313, 8-313 or 8-321 thereof); and (d) notifications to persons
holding such property, and acknowledgments, receipts or confirmations from
persons holding such property, shall be deemed notifications to, or
acknowledgments, receipts or confirmations from, financial intermediaries,
bailees or agents (as applicable) of the Issuer for the purpose of perfecting
such security interest under applicable law.

      (b) The Depositor and, at the Depositor's direction, the Issuer shall,
to the extent consistent with this Agreement, take such reasonable actions as
may be necessary to ensure that, if this Agreement were deemed to create a
security interest in the Mortgage Loans and the other property of the Trust
Estate, 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 this Agreement. Without limiting the generality of the
foregoing, the Depositor shall prepare and file any UCC financing statements
that are necessary to perfect the Indenture Trustee's security interest in or
lien on the Mortgage Loans, as evidenced by an Officer's Certificate of the
Depositor, and furnish a copy of each such filed financing statement to the
Trust Administrator. The Trust Administrator shall prepare and file, at the
expense of the Issuer, all filings necessary to maintain the effectiveness of
any original filings necessary under the Relevant UCC to perfect the Indenture
Trustee's security interest in or lien on the Mortgage Loans, including
without limitation (x) continuation statements, and (y) to the extent that a
Responsible Officer of the

                                      57
<PAGE>

Trust Administrator has received written notice of such change or transfer,
such other statements as may be occasioned by (1) any change of name of the
Seller, the Depositor or the Issuer, (2) any change of location of the place
of business or the chief executive office of the Seller or the Depositor or
(3) any transfer of any interest of the Seller or the Depositor in any
Mortgage Loan.

      Neither the Depositor nor the Issuer shall organize under the law of any
jurisdiction other than the State under which each is organized as of the
Closing Date (whether changing its jurisdiction of organization or organizing
under an additional jurisdiction) without giving [30] days' prior written
notice of such action to its immediate and mediate transferee, including the
Indenture Trustee. Before effecting such change, each of the Depositor or the
Issuer proposing to change its jurisdiction of organization shall prepare and
file in the appropriate filing office any financing statements or other
statements necessary to continue the perfection of the interests of its
immediate and mediate transferees, including the Indenture Trustee, in the
Mortgage Loans. In connection with the transactions contemplated by this
Agreement and the Indenture, each of the Depositor and the Issuer authorizes
its immediate or mediate transferee to file in any filing office any initial
financing statements, any amendments to financing statements, any continuation
statements, or any other statements or filings described in this Section
2.03(b).

      (c) The Depositor shall not take any action inconsistent with the sale
by the Depositor of all of its right, title and interest in and to the Trust
Estate and shall indicate or shall cause to be indicated in its records and
records held on its behalf that ownership of each Mortgage Loan and the other
property of the Issuer is held by the Issuer. In addition, the Depositor shall
respond to any inquiries from third parties with respect to ownership of a
Mortgage Loan or any other property of the Trust Estate by stating that it is
not the owner of such Mortgage Loan and that ownership of such Mortgage Loan
or other property of the Trust Estate is held by the Issuer on behalf of the
Noteholders.

      Section 2.04. Option to Contribute Derivative Instrument.

      At any time on or after the Closing Date, the Seller shall have the
right to contribute to, and deposit into, the Trust a derivative contract or
comparable instrument (a "Derivative Instrument"). The Derivative Instrument
may have a notional amount in excess of the sum of the beneficial interests in
the Trust. Any such instrument shall constitute a fully prepaid agreement. The
Trust Administrator shall have no tax reporting duties with respect to any
such Derivative Instrument.

                                 ARTICLE III

                        REPRESENTATIONS AND WARRANTIES

      Section 3.01. Representations and Warranties of the Depositor and the
Seller.

      (a) The Depositor hereby represents and warrants to the Issuer, the
Indenture Trustee for the benefit of Noteholders, the Trust Administrator, the
Master Servicer, the Seller and the Servicer as of the Closing Date or such
other date as is specified, that:

            (i) This Agreement constitutes a legal, valid and binding
      obligation of the Depositor, enforceable against the Depositor in

<PAGE>

      enforceability may be limited by applicable bankruptcy, insolvency,
      reorganization, moratorium or other similar laws now or hereafter in
      effect affecting the enforcement of creditors' rights in general and
      except as such enforceability may be limited by general principles of
      equity (whether considered in a proceeding at law or in equity);

            (ii) Immediately prior to the transfer by the Depositor to the
      Trust Estate of each Mortgage Loan, the Depositor had good and equitable
      title to each Mortgage Loan (insofar as such title was conveyed to it by
      the Seller) subject to no prior lien, claim, participation interest,
      mortgage, security interest, pledge, charge or other encumbrance or
      other interest of any nature;

            (iii) As of the Closing Date, the Depositor has transferred all
      right, title and interest in the Initial Mortgage Loans to the Trust
      Estate;

            (iv) As of the Subsequent Transfer Date, the Depositor has
      transferred all right, title and interest in the Subsequent Mortgage
      Loans to the Trust Estate

      Trust Estate with any intent to hinder, delay or defraud any of its
      creditors;

            (vi) The Depositor has been duly organized and is validly existing
      as a corporation in good standing under the laws of the State of
      Delaware, with full power and authority to own its assets and conduct

      (b) The Seller hereby represents and warrants to the Issuer, the

      existing and in good standing under the laws of the _____________, and
      has the corporate power to own its assets and to transact the business
      in which it is currently engaged. The Seller is duly qualified to do
      business as a foreign corporation and is in good standing in each
      jurisdiction in which the character of the business transacted by it or
      any properties owned or leased by it requires such qualification and in
      which the failure so to qualify would have a material adverse effect on
      the business, properties, assets, or condition (financial or other) of
      the Seller;

            (ii) the Seller has the corporate power and authority to make,
      execute, deliver and perform this Agreement and all of the transactions
      contemplated under the Agreement, and has taken all necessary corporate

      Agreement. When executed and delivered, this Agreement will constitute
      the legal, valid and binding obligation of the Seller enforceable in
      accordance with its terms, except as enforcement of such terms may be
      limited by bankruptcy, insolvency or similar laws affecting the
      enforcement of creditors' rights generally and by the availability of
      equitable remedies;

            (iii) the Seller is not required to obtain the consent of any
      other party or any consent, license, approval or authorization from, or
      registration or declaration with, any

                                      59
<PAGE>

      governmental authority, bureau or agency in connection with the
      execution, delivery, performance, validity or enforceability of this
      Agreement, except for such consent, license, approval or authorization,
      or registration or declaration, as shall have been obtained or filed, as
      the case may be, prior to the Closing Date;

            (iv) the execution, delivery and performance of this Agreement by
      the Seller will not violate any provision of any existing law or
      regulation or any order or decree of any court applicable to the Seller
      or any provision of the articles of incorporation or bylaws of the
      Seller, or constitute a material breach of any mortgage, indenture,
      contract or other agreement to which the Seller is a party or by which
      the Seller may be bound;

            (v) no litigation or administrative proceeding of or before any
      court, tribunal or governmental body is currently pending, or to the
      knowledge of the Seller threatened, against the Seller or any of its
      properties or with respect to this Agreement which in the opinion of the
      Seller has a reasonable likelihood of resulting in a material adverse
      effect on the transactions contemplated by this Agreement; and

            (vi) [the Seller has been organized in conformity with the
      requirements for qualification as a REIT; the Seller has filed an
      election to be treated as a REIT for federal income tax purposes; and
      the Seller currently qualifies as, and it proposes to operate in a
      manner that will enable it to continue to qualify as, a REIT.]

      (c) The Seller hereby represents and warrants to the Issuer, the
Indenture Trustee for the benefit of Noteholders, the Trust Administrator, the
Master Servicer and the Depositor as of the Closing Date with respect to the
Initial Mortgage Loans and the Subsequent Transfer Date with respect to the
Subsequent Transfer Date or such other date as is specified, with respect to
the Mortgage Loans, the representations and warranties set forth in Schedule
II of the Mortgage Loan Purchase Agreement.

      (d) 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 subsection (c) above or the Mortgage Loan Purchase Agreement, the
only right or remedy of the Indenture Trustee or any Certificateholder
hereunder shall be their rights to enforce the obligations of the Seller under
any applicable representation or warranty made by it. The Indenture Trustee on
behalf of the Issuer 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 3.01(a)(ii))
under any circumstances.

      Section 3.02. Discovery of Breach. It is understood and agreed that the
representations and warranties (i) of the Depositor set forth in Section
3.01(a), (ii) of the Seller set forth in Section 3.01(b) and (c) and (iii) of
the Servicer pursuant to Section 4.05 of this Agreement, shall each survive
delivery of the Mortgage Files and the Assignment of Mortgage of each Mortgage
Loan to the Indenture Trustee and shall continue throughout the term of this
Agreement. With respect to the representations and warranties which are made
to the best of the Seller's knowledge, if it is discovered by the Depositor,
the Seller, the Trust Administrator, the Indenture Trustee, the Master
Servicer, the Underwriters or the Servicer that the substance of such
representation and warranty is inaccurate and such inaccuracy materially and
adversely affects

                                      60
<PAGE>

the value of the Mortgage Loans or the interests of the Noteholders or the
Indenture Trustee therein, notwithstanding such Seller's lack of knowledge
with respect to the substance of such representation or warranty, remedies for
breach will apply to such inaccuracy. Any breach of the representation and
warranty set forth in clauses (g), (ss), (tt) and (vv) of Schedule II of the
Mortgage Loan Purchase Agreement shall be deemed to materially and adversely
affect the interest of the Trust in that Mortgage Loan, notwithstanding the
Seller's lack of knowledge with respect to the substance of such
representation and warranty. Upon discovery by any of the Depositor, the
Master Servicer, the Trust Administrator or the Indenture Trustee of a breach
of any of such representations and warranties made by the Seller that
adversely and materially affects the value of the related Mortgage Loan, the
party discovering such breach shall give prompt written notice to the other
parties. Within [60] days of the discovery by the Seller of a breach of any
representation or warranty given to the Indenture Trustee by the Seller or the
Seller's receipt of written notice of such a breach, 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 Indenture Trustee at
the Purchase Price or (c) substitute a Qualifying Substitute Mortgage Loan for
the affected Mortgage Loan.

      Section 3.03. Repurchase, Purchase or Substitution of Mortgage Loans.

      (a) With respect to any Mortgage Loan repurchased by the Seller pursuant
to Section 3.02(b) of this Agreement, the principal portion of the funds in
respect of such repurchase of a Mortgage Loan will be considered a Principal
Prepayment and the Purchase Price shall be deposited in the Collection
Account. Upon receipt by the Trust Administrator of the full amount of the
Purchase Price for a Deleted Mortgage Loan and notification thereof has been
made to the Indenture Trustee, or upon receipt of notification from the
Custodian that it had received the Mortgage File for a Qualifying Substitute
Mortgage Loan substituted for a Deleted Mortgage Loan (and any applicable
Substitution Amount), the Indenture Trustee 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 and the Indenture, which instruments
shall be prepared by the Servicer and the Indenture Trustee shall have no
further responsibility with respect to the Mortgage File relating to such
Deleted Mortgage Loan.

      (b) With respect to each Qualifying Substitute Mortgage Loan to be
delivered to the Indenture Trustee (or its custodian) in exchange for a
Deleted Mortgage Loan: (i) the Depositor or the Seller, as applicable, must
deliver to the Indenture Trustee (or a Custodian) the Mortgage File for the
Qualifying Substitute Mortgage Loan containing the documents set forth in
Section 2.01(b) along with a written certification certifying as to the
delivery of such Mortgage File and containing the granting language set forth
in Section 2.01(a); and (ii) the Seller and the Depositor will be deemed to
have made, with respect to such Qualifying Substitute Mortgage Loan, each of
the representations and warranties made by it with respect to the related
Deleted Mortgage Loan. As soon as practicable after the delivery of any
Qualifying Substitute Mortgage Loan hereunder, the Indenture Trustee, at the
expense of the Depositor and at the direction and with the cooperation of the
Servicer shall (i) with respect to a Qualifying Substitute Mortgage Loan that
is

                                      61
<PAGE>

a Non-MERS Mortgage Loan, cause the Assignment of Mortgage to be recorded by
the Servicer if required pursuant to Section 2.01(c), or (ii) with respect to
a Qualifying Substitute Mortgage Loan that is a MERS Mortgage Loan, cause to
be taken such actions as are necessary to cause the Indenture Trustee (on
behalf of the Issuer) to be clearly identified as the owner of each such
Mortgage Loan on the records of MERS if required pursuant to Section 2.01(c).

                                  ARTICLE IV

                      ADMINISTRATION AND SERVICING OF THE
                        MORTGAGE LOANS BY THE SERVICER

      Section 4.01. Seller's Engagement of Servicer to Perform Servicing
Responsibilities.

      (a) Contract for Servicing; Possession of Servicing Files. The Seller,
as the owner of the servicing rights, by execution and delivery of this
Agreement, does hereby contract with the Servicer for the servicing of the
Mortgage Loans for the benefit of the Issuer and the Indenture Trustee. The
Servicer shall maintain a Servicing File with respect to each Mortgage Loan in
order to service such Mortgage Loans pursuant to this Agreement and each
Servicing File delivered to the Servicer shall be held in trust by the
Servicer for the benefit of the Issuer and the Indenture Trustee; provided,
however, that the Servicer shall not have any liability for any Servicing
Files (or portions thereof) not delivered by the Seller. The Servicer's
possession of any portion of the Mortgage Loan documents shall be at the will
of the Indenture Trustee for the sole purpose of facilitating servicing of the
related Mortgage Loan pursuant to this Agreement, and such retention and
possession by the Servicer shall be in a custodial capacity only. The
ownership of each Mortgage Note, Mortgage, and the contents of the Servicing
File shall be vested in the Indenture Trustee and the ownership of all records
and documents with respect to the related Mortgage Loan prepared by or which
come into the possession of the Servicer shall immediately vest in the
Indenture Trustee and shall be retained and maintained, in trust, by the
Servicer at the will of the Indenture Trustee in such custodial capacity only.
The Servicing File retained by the Servicer pursuant to this Agreement shall
be identified in accordance with the Servicer's file tracking system to
reflect the ownership of the related Mortgage Loan by the Indenture Trustee.
The Servicer shall release from its custody the contents of any Servicing File
retained by it only in accordance with this Agreement.

      (b) Books and Records. All rights arising out of the Mortgage Loans
shall be vested in the Indenture Trustee, subject to the Servicer's rights to
service and administer the Mortgage Loans hereunder in accordance with the
terms of this Agreement. All funds received on or in connection with a
Mortgage Loan, other than the Master Servicing Fee, the Servicing Fee and
other compensation and reimbursement to which the Servicer and the Master
Servicer are entitled as set forth herein, including but not limited to
Section 4.04(c), Section 5.07(e) and Section 5.21 shall be received and held
by them in trust for the benefit of the Indenture Trustee pursuant to the
terms of this Agreement.

            The Servicer shall forward to the Custodian original documents
evidencing an assumption, modification, consolidation or extension of any
Mortgage Loan entered into in accordance with Section 4.02(a) within one week
of their execution; provided, however, that the Servicer shall provide the
Custodian with a Servicer certified true copy of any such document

                                      62
<PAGE>

submitted for recordation within one week of its execution, and shall provide
the original of any document submitted for recordation or a copy of such
document certified by the appropriate public recording office to be a true and
complete copy of the original within [120] days of its submission for
recordation.

      Section 4.02. Servicing of the Mortgage Loans.

      (a) Servicer to Service. The Servicer, acting directly or through one or
more sub-servicers as provided in Section 4.09 shall service and administer
the Mortgage Loans from and after the Closing Date and, except where prior
consent or approval of the Master Servicer is required under this Agreement,
shall have full power and authority, acting alone, to do any and all things in
connection with such servicing and administration which the Servicer may deem
necessary or desirable, consistent with the terms of this Agreement and with
the Servicing Standard.

            Consistent with the terms of this Agreement, the Servicer may
waive, modify or vary any term of any Mortgage Loan or consent to the
postponement of strict compliance with any such term or in any manner grant
indulgence to any Mortgagor, including (i) waiving any late payment charge and
(ii) extending the due dates for payments due on a Mortgage Note for a period
not greater than [120] days; provided, however, that the maturity of any
Mortgage Loan shall not be extended past the date on which the final payment
is due on the latest maturing Mortgage Loan as of the Cut-off Date. Such
waiver, modification, postponement or indulgence may be made if in the
Servicer's reasonable and prudent determination such waiver, modification,
postponement or indulgence is not materially adverse to the interests of the
Issuer, the Indenture Trustee and the Noteholders; provided, however, that
unless the Servicer has obtained the prior written consent of the Master
Servicer, the Servicer shall not permit any modification with respect to any
Mortgage Loan that would change the Mortgage Rate, defer or forgive the
payment of principal or interest, reduce or increase the outstanding principal
balance (except for actual payments of principal) or change the final maturity
date on such Mortgage Loan, other than as provided in clauses (i) and (ii) of
the immediately preceding sentence. In the event of any such modification
which permits the deferral of interest or principal payments on any Mortgage
Loan, the Servicer shall, on the Business Day immediately preceding the
Servicer Remittance Date in any month in which any such principal or interest
payment has been deferred, make an Advance in accordance with Section 4.03(c)
in an amount equal to the difference between (a) such month's principal and
one month's interest at the Mortgage Loan Remittance Rate on the unpaid
principal balance of such Mortgage Loan and (b) the amount paid by the
Mortgagor. The Servicer shall be entitled to reimbursement for such advances
to the same extent as for all other Advances made pursuant to Section 4.03.
Without limiting the generality of the foregoing, the Servicer shall continue,
and is hereby authorized and empowered, to execute and deliver on behalf of
itself, the Issuer and the Indenture Trustee, all instruments of satisfaction
or cancellation, or of partial or full release, discharge and all other
comparable instruments, with respect to the Mortgage Loans and with respect to
the Mortgaged Properties. The Indenture Trustee shall execute and deliver to
the Servicer powers of attorney (on the standard form used by the Indenture
Trustee) and other documents, furnished to it by the Servicer and reasonably
satisfactory to the Indenture Trustee, necessary or appropriate to enable the
Servicer to carry out its servicing and administrative duties under this
Agreement; provided that the Indenture Trustee shall not be liable for the
actions of the Servicer under any such

                                      63
<PAGE>

powers of attorney. Promptly after the execution of any assumption,
modification, consolidation or extension of any Mortgage Loan, the Servicer
shall forward to the Master Servicer copies of any documents evidencing such
assumption, modification, consolidation or extension.

            In servicing and administering the Mortgage Loans, the Servicer
shall adhere to the Servicing Standard. Notwithstanding the appointment of any
sub-servicer pursuant to Section 4.09, the Servicer shall remain liable for
the performance of all of the servicing obligations and responsibilities under
this Agreement.

      (b) Servicer Discretion. In managing the liquidation of defaulted
Mortgage Loans, the Servicer will have sole discretion, subject to the terms
of this Agreement, to sell defaulted Mortgage Loans; provided, however, that
the Servicer shall not take any action that is inconsistent with or prejudices
the interests of the Noteholders in any Mortgage Loan or the rights and
interests of the Depositor, the Indenture Trustee and the Noteholders under
this Agreement.

      (c) Collection and Liquidation of Mortgage Loans. Continuously from the
Closing Date, until the date each Mortgage Loan ceases to be subject to this
Agreement, the Servicer shall proceed diligently to collect all payments due
under each of the Mortgage Loans when the same shall become due and payable
and shall take special care in ascertaining and estimating Escrow Payments and
all other charges that will become due and payable with respect to the
Mortgage Loans and each related Mortgaged Property, to the end that the
installments payable by the Mortgagors will be sufficient to pay such charges
as and when they become due and payable.

            The Servicer shall use its best efforts, consistent with the
Servicing Standard to foreclose upon or otherwise comparably convert the
ownership of such Mortgaged Properties as come into and continue in default
and as to which no satisfactory arrangements can be made for collection of
delinquent payments pursuant to Section 4.02(a). The Servicer shall use its
best efforts to realize upon defaulted Mortgage Loans in such a manner as will
maximize the receipt of principal and interest by the Trust, taking into
account, among other things, the timing of foreclosure proceedings. The
foregoing is subject to the provisions that, in any case in which Mortgaged
Property shall have suffered damage, the Servicer shall not be required to
expend its own funds toward the restoration of such property unless it shall
determine in its discretion (i) that such restoration will increase the
proceeds of liquidation of the related Mortgage Loan to the Issuer after
reimbursement to itself for such expenses, and (ii) that such expenses will be
recoverable by the Servicer through Insurance Proceeds or Liquidation Proceeds
from the related Mortgaged Property. In the event that any payment due under
any Mortgage Loan and not otherwise postponed, deferred or waived pursuant to
Section 4.02 is not paid when the same becomes due and payable, or in the
event the Mortgagor fails to perform any other covenant or obligation under
the Mortgage Loan and such failure continues beyond any applicable grace
period, the Servicer shall take such action as (1) shall be consistent with
the Servicing Standard and (2) the Servicer shall determine prudently to be in
the best interest of the Issuer, the Indenture Trustee and the Noteholders. In
the event that any payment due under any Mortgage Loan is not otherwise
postponed, deferred or waived pursuant to Section 4.02(a) and remains
delinquent for a period of [105] days or any other default continues for a
period of [105] days beyond the expiration of any grace or cure period, the
Servicer shall commence foreclosure

                                      64

proceedings. The Servicer shall notify the Master Servicer in writing of the
commencement of foreclosure proceedings on a monthly basis no later than the
[fifth] Business Day of each month (which notification may be included within
the monthly reports submitted to the Master Servicer under Section 4.03(b)
this Agreement). In such connection, the Servicer shall be responsible for all
costs and expenses incurred by it in any such proceedings; provided, however,
that it shall be entitled to reimbursement thereof from the related Mortgaged
Property, as contemplated in Sections 4.02(e) and 4.02(p) or as otherwise
provided in Section 4.02(e)(4).

            Notwithstanding the generality of the preceding paragraph, the
Servicer shall take such actions generally in accordance with the Servicer's
established default timeline and in accordance with the Servicing Standard
with respect to each Mortgage Loan and Mortgagor for which there is a
delinquency until such time as the related Mortgagor is current with all
payments due under the Mortgage Loan.

      (d) Establishment of and Deposits to Custodial Account.

            (i) The Servicer shall segregate and hold all funds collected and
      received pursuant to the Mortgage Loans separate and apart from any of
      its own funds and general assets and shall initially establish and
      maintain one or more Custodial Accounts, in the form of time deposit or
      demand accounts, each of which accounts shall be titled "_________________
      in trust for ____________________________________, as Indenture Trustee,
      for ______ Mortgage Investment Trust 200_-__ Mortgage Backed Notes,
      Series 200_-__" and referred to herein as a "Custodial Account." Each
      Custodial Account shall be an Eligible Account. Any funds deposited in
      the Custodial Account may be invested in Eligible Investments subject to
      the provisions of Section 4.02(j) hereof. Funds deposited in the
      Custodial Account may be drawn on by the Servicer in accordance with
      Section 4.02(e) hereof. The creation of any Custodial Account shall be
      evidenced by a letter agreement in the form of Exhibit E hereto. A copy
      of such certification or letter agreement shall be furnished to the
      Indenture Trustee, the Master Servicer and, upon request, to any
      subsequent owner of the Mortgage Loans. The Servicer shall deposit or
      cause to be deposited into the Custodial Account, no later than the
      Business Day following the Closing Date, any amounts received with
      respect to the Mortgage Loans representing Scheduled Payments on the
      Mortgage Loans due after the Cut-off Date and unscheduled payments
      received on or after the Cut-off Date and on or before the Closing Date.

            (ii) The Servicer shall deposit in the Custodial Account on a
      daily basis, but not more than [two] Business Days after receipt by the
      Servicer and retain therein, the following collections received by the
      Servicer and payments made by the Servicer after the related Cut-off
      Date (other than scheduled payments of principal and interest due on or
      before the related Cut-off Date), as applicable:

                        (1) all payments on account of principal on the
                  Mortgage Loans, including all Principal Prepayments and all
                  Prepayment Premiums;

                                      65
<PAGE>

                        (2) all payments on account of interest on the
                  Mortgage Loans adjusted to the Mortgage Loan Remittance
                  Rate;

                        (3) all Liquidation Proceeds (net of Liquidation
                  Expenses);

                        (4) all Insurance Proceeds including amounts required
                  to be deposited pursuant to Section 4.02(k) (other than
                  proceeds to be held in the Escrow Account and applied to the
                  restoration and repair of the Mortgaged Property or released
                  to the Mortgagor in accordance with Section 4.02(k));

                        (5) all Condemnation Proceeds that are not applied to
                  the restoration or repair of the Mortgaged Property or
                  released to the Mortgagor in accordance with Section
                  4.02(o);

                        (6) with respect to each Principal Prepayment in full
                  or in part, the Prepayment Interest Shortfall Amount, if
                  any, for the month of payment. Such deposit shall be made
                  from the Servicer's own funds, without reimbursement
                  therefor, up to a maximum amount per month in the aggregate
                  of the Servicing Fee, actually received for such month for
                  the Mortgage Loans;

                        (7) all Advances made by the Servicer pursuant to
                  Section 4.03(c);

                        (8) any amounts received from the Seller, the
                  Depositor or any other person giving representations and
                  warranties with respect to the Mortgage Loans, in connection
                  with the repurchase of any Mortgage Loan;

                        (9) any amounts required to be deposited by the
                  Servicer pursuant to Section 4.02(k) in connection with the
                  deductible clause in any blanket hazard insurance policy;

                        (10) any amounts received with respect to or related
                  to any REO Property or REO Disposition Proceeds pursuant to
                  Section 4.02(p); and

                        (11) any other amounts required to be deposited in the
                  Custodial Account pursuant to this Agreement.

            The foregoing requirements for deposit into the Custodial Account
      shall be exclusive, it being understood and agreed that, without
      limiting the generality of the foregoing, payments in the nature of the
      Servicing Fee, Prepayment Interest Excess Amounts and Ancillary Income
      need not be deposited by the Servicer into the Custodial Account. Any
      interest paid on funds deposited in the Custodial Account by the
      depository institution maintaining such account shall accrue to the
      benefit of the Servicer

                                      66
<PAGE>

      and the Servicer shall be entitled to retain and withdraw such interest
      from the Custodial Account pursuant to Section 4.02(e). Additionally,
      any other benefit derived from the Custodial Account associated with the
      receipt, disbursement and accumulation of principal, interest, taxes,
      hazard insurance, mortgage insurance, etc. shall accrue to the Servicer.

            (iii) The Servicer agrees that it shall not create, incur or
      subject any Mortgage Loans, or any funds that are deposited in any
      Custodial Account or Escrow Account, or any funds that otherwise are or
      may become due or payable to or for the benefit of the Indenture
      Trustee, to any claim, lien, security interest, judgment, levy, writ of
      attachment or other encumbrance, nor assert by legal action or otherwise
      any claim or right of setoff against any Mortgage Loan or any funds
      collected on, or in connection with, a Mortgage Loan.

            (iv) The Servicer shall be responsible for reviewing and
      reconciling each Custodial Account and Escrow Account in accordance with
      industry standards of prudent residential mortgage loan servicers, and
      shall act promptly to resolve any discrepancies in any such account. The
      Servicer shall be responsible and liable for all expenses incurred by
      the other parties hereto resulting from, and all consequences for, the
      Servicer's failure to properly and promptly reconcile each such account.

      (e) Permitted Withdrawals from Custodial Account.

      The Servicer shall, from time to time, withdraw funds from the Custodial
Account for the following purposes:

                        (1) to make payments to the Master Servicer in the
                  amounts and in the manner provided for in Section 4.03(a);

                        (2) in the event the Servicer has elected not to
                  retain the Servicing Fee out of any Mortgagor payments on
                  account of interest or other recovery of interest with
                  respect to a particular Mortgage Loan (including late
                  collections of interest on such Mortgage Loan, or interest
                  portions of Insurance Proceeds, Liquidation Proceeds or
                  Condemnation Proceeds) prior to the deposit of such
                  Mortgagor payment or recovery into the Custodial Account, to
                  pay to itself the related Servicing Fee from all such
                  Mortgagor payments on account of interest or other such
                  recovery for interest with respect to that Mortgage Loan;

                        (3) to reimburse itself for unreimbursed Advances and
                  Servicing Advances, the Servicer's right to reimburse itself
                  pursuant to this subclause (3) with respect to any Mortgage
                  Loan being limited to related Liquidation Proceeds (net of
                  Liquidation Expenses), Condemnation Proceeds, Insurance
                  Proceeds, REO Disposition Proceeds and other amounts
                  received in respect of

                                      67
<PAGE>

                  the related REO Property, and such other amounts as may be
                  collected by the Servicer from the Mortgagor or otherwise
                  relating to such Mortgage Loan, it being understood that, in
                  the case of any such reimbursement, the Servicer's right
                  thereto shall be prior to the rights of the Noteholders;

                        (4) to reimburse itself for any previously
                  unreimbursed Advances or Servicing Advances that it
                  determines are Nonrecoverable Advances, it being understood,
                  in the case of each such reimbursement, that the Servicer's
                  right thereto shall be prior to the rights of the
                  Noteholders;

                        (5) to pay itself investment earnings on funds
                  deposited in the Custodial Account;

                        (6) to transfer funds to another Eligible Account in
                  accordance with Section 4.02(j) hereof;

                        (7) to invest funds in certain Eligible Investments in
                  accordance with Section 4.02(d)(i) and Section 4.02(j)
                  hereof;

                        (8) to withdraw funds deposited in error;

                        (9) to clear and terminate the Custodial Account upon
                  the termination of this Agreement; and

                        (10) to pay itself any Prepayment Interest Excess
                  Amount.

      (f) Establishment of and Deposits to Escrow Account. The Servicer shall
segregate and hold all funds collected and received pursuant to a Mortgage
Loan constituting Escrow Payments separate and apart from any of its own funds
and general assets and shall establish and maintain one or more Escrow
Accounts, in the form of time deposit or demand accounts, titled
"_________________________ in trust for ____________________________________,
as Indenture Trustee, for ______ Mortgage Investment Trust 200_-__." The
Escrow Accounts shall be established with an Eligible Institution. Nothing
herein shall require the Servicer to compel a Mortgagor to establish an Escrow
Account in violation of applicable law. Funds deposited in the Escrow Account
may be drawn on by the Servicer in accordance with Section 4.02(g). The
creation of any Escrow Account shall be evidenced by a letter agreement in the
form of Exhibit F hereto. A copy of such certification or letter agreement
shall be furnished to the Master Servicer.

            The Servicer shall deposit in the Escrow Account or Accounts on a
daily basis, and retain therein:

            (i) all Escrow Payments collected on account of the Mortgage
      Loans, for the purpose of effecting timely payment of any such items as
      required under the terms of this Agreement; and

                                      68
<PAGE>

            (ii) all amounts representing Insurance Proceeds or Condemnation
      Proceeds which are to be applied to the restoration or repair of any
      Mortgaged Property.

            The Servicer shall make withdrawals from the Escrow Account only
to effect such payments as are required under this Agreement, as set forth in
Section 4.02(g). The Servicer shall be entitled to retain any interest
earnings paid on funds deposited in the Escrow Account by the depository
institution, other than interest on escrowed funds required by law to be paid
to the Mortgagor. To the extent required by law, the Servicer shall pay
interest on escrowed funds to the Mortgagor notwithstanding that the Escrow
Account may be non-interest bearing or the interest earnings paid thereon are
insufficient for such purposes.

      (g) Permitted Withdrawals from Escrow Account. Withdrawals from the
Escrow Account or Accounts may be made by the Servicer only:

            (i) to effect timely payments of ground rents, taxes, assessments,
      water rates, mortgage insurance premiums, condominium charges, fire and
      hazard insurance premiums or other items constituting Escrow Payments
      for the related Mortgage;

            (ii) to reimburse the Servicer for any Servicing Advance of an
      Escrow Payment made by the Servicer with respect to a related Mortgage
      Loan, but only from amounts received on the related Mortgage Loan which
      represent late collections of Escrow Payments thereunder;

            (iii) to refund to any Mortgagor any funds found to be in excess
      of the amounts required to be escrowed under the terms of the related
      Mortgage Loan;

            (iv) to the extent permitted by applicable law, for transfer to
      the Custodial Account and application to reduce the principal balance of
      the Mortgage Loan in accordance with the terms of the related Mortgage
      and Mortgage Note;

            (v) for application to restoration or repair of the Mortgaged
      Property in accordance with Section 4.02(o);

            (vi) to pay to the Servicer, or any Mortgagor to the extent
      required by law, any interest paid on the funds deposited in the Escrow
      Account; and

            (vii) to clear and terminate the Escrow Account on the termination
      of this Agreement.

            The Servicer will be responsible for the administration of the
Escrow Accounts and will be obligated to make Servicing Advances to the Escrow
Account in respect of its obligations under this 4.02(g), reimbursable from
the Escrow Accounts or Custodial Account to the extent not collected from the
related Mortgagor, anything to the contrary notwithstanding, when and as
necessary to avoid the lapse of insurance coverage on the Mortgaged Property,
or which the Servicer knows, or in servicing the Mortgage Loans in accordance
with the Servicing Standard should know, 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. If any such payment has not been made and the Servicer receives notice
of a tax lien with respect to the Mortgage being imposed, the Servicer

                                      69
<PAGE>

will advance or cause to be advanced funds (which will constitute a Servicing
Advance) necessary to discharge such lien on the Mortgaged Property in order
to prevent loss of title to the Mortgaged Property.

      (h) Notification of Adjustments. With respect to each Mortgage Loan, the
Servicer shall adjust the Mortgage Rate on the related interest rate
adjustment date and shall adjust the Scheduled Payment on the related mortgage
payment adjustment date, if applicable, in compliance with the requirements of
applicable law and the related Mortgage and Mortgage Note. The Servicer shall
execute and deliver any and all necessary notices required under applicable
law and the terms of the related Mortgage Note and Mortgage regarding the
Mortgage Rate and Scheduled Payment adjustments. The Servicer shall promptly,
upon written request therefor, deliver to the Master Servicer such
notifications and any additional applicable data regarding such adjustments
and the methods used to calculate and implement such adjustments. Upon the
discovery by the Servicer or the receipt of notice from the Master Servicer
that the Servicer has failed to adjust a Mortgage Rate or Scheduled Payment in
accordance with the terms of the related Mortgage Note, the Servicer shall
immediately deposit in the Custodial Account from its own funds the amount of
any interest loss or deferral caused the Seller thereby.

      (i) Payment of Taxes, Insurance and Other Charges.

            (i) With respect to each Mortgage Loan which provides for Escrow
      Payments, the Servicer shall maintain accurate records reflecting the
      status of ground rents, taxes, assessments, water rates, sewer rents,
      and other charges which are or may become a lien upon the Mortgaged
      Property and the status of fire and hazard insurance coverage and shall
      obtain, from time to time, all bills for the payment of such charges
      (including renewal premiums) ("Property Charges") and shall effect
      payment thereof prior to the applicable penalty or termination date,
      employing for such purpose deposits of the Mortgagor in the Escrow
      Account which shall have been estimated and accumulated by the Servicer
      in amounts sufficient for such purposes, as allowed under the terms of
      the Mortgage. The Servicer shall effect timely payment of all such
      charges (which will constitute Servicing Advances) irrespective of each
      Mortgagor's faithful performance in the payment of the same or the
      making of the Escrow Payments if necessary to avoid a lien or loss on
      the Mortgaged Property.

            (ii) To the extent that a Mortgage does not provide for Escrow
      Payments, the Servicer shall make Servicing Advances from its own funds
      to effect payment of all Property Charges upon receipt of notice of any
      failure to pay on the part of the Mortgagor, or at such other time as
      the Servicer determines to be in the best interest of the Trust;
      provided, that in any event the Servicer shall pay such charges on or
      before any date by which payment is necessary to preserve the lien
      status of the Mortgage. The Servicer shall pay any late fee or penalty
      (which will constitute Servicing Advances) which is payable due to any
      delay in payment of any Property Charge and necessary to avoid a lien on
      or loss on Mortgage Property.

      (j) Protection of Accounts. The Servicer may transfer the Custodial
Account or the Escrow Account to a different Eligible Institution from time to
time. Such transfer shall be made only upon obtaining the consent of the
Master Servicer, which consent shall not be withheld

                                      70
<PAGE>

unreasonably, and the Servicer shall give notice to the Master Servicer and
the Indenture Trustee of any change in the location of the Custodial Account.

            The Servicer shall bear any expenses, losses or damages sustained
by the Master Servicer or the Indenture Trustee if the Custodial Account
and/or the Escrow Account are not Eligible Accounts.

            Amounts on deposit in the Custodial Account may be invested at the
option of the Servicer, but only in Eligible Investments. Any such Eligible
Investment with respect to the Custodial Account shall mature no later than
[two] Business Days prior to the Servicer Remittance Date in each month;
provided, however, that if such Eligible Investment is an obligation of an
Eligible Institution (other than the Servicer) that maintains the Custodial
Account, then such Eligible Investment may mature on the related Servicer
Remittance Date. Any such Eligible Investment shall be made in the name of the
Servicer in trust for the benefit of the Indenture Trustee. All income on or
gain realized from any such Eligible Investment shall be for the benefit of
the Servicer and may be withdrawn at any time by the Servicer. Any losses
incurred in respect of any such investment shall be deposited in the Custodial
Account by the Servicer out of its own funds immediately as realized. If, at
any time, the amount on deposit in the Custodial Account exceeds the amount of
the applicable FDIC insurance, such excess above the amount of the applicable
FDIC insurance shall be invested in Eligible Investments.

      (k) Maintenance of Hazard Insurance. The Servicer shall cause to be
maintained for each Mortgage Loan hazard insurance such that all buildings
upon the related Mortgaged Property are insured by a generally acceptable
insurer acceptable under the Servicing Standard against loss by fire, hazards
of extended coverage and such other hazards as are customary in the area where
the Mortgaged Property is located, in an amount which is at least equal to the
lesser of (i) the replacement value of the improvements securing such Mortgage
Loan and (ii) the greater of (a) the outstanding principal balance of the
Mortgage Loan plus accrued interest thereon and the good faith estimate of the
Servicer of the related Liquidation Expenses to be incurred in connection
therewith and (b) an amount such that the proceeds thereof shall be sufficient
to prevent the Mortgagor or the loss payee from becoming a co-insurer. The
Servicer shall be under no obligation to require any Mortgagor to obtain
earthquake or other additional insurance and shall be under no obligation
itself to maintain any such additional insurance on property acquired in
respect of a Mortgage Loan, other than pursuant to such applicable laws and
regulations as shall at any time be in force and as shall require such
additional insurance.

            If upon origination of the Mortgage Loan the related Mortgaged
Property was located in an area identified in the Federal Register by the
Flood Emergency Management Agency as having special flood hazards (and such
flood insurance has been made available), a flood insurance policy meeting the
requirements of the current guidelines of the Federal Insurance Administration
shall be in effect with a generally acceptable insurance carrier acceptable
under the Servicing Standard in an amount representing coverage equal to the
lesser of (i) the minimum amount required, under the terms of coverage, to
compensate for any damage or loss on a replacement cost basis (or the unpaid
balance of the mortgage if replacement cost coverage is not available for the
type of building insured) and (ii) the maximum amount of insurance which is
available under the Flood Disaster Protection Act of 1973, as amended. If at
any time during the term of the Mortgage Loan, the Servicer determines in
accordance with

                                      71
<PAGE>

applicable law and pursuant to the Servicing Standard that a Mortgaged
Property is located in a special flood hazard area and is not covered by flood
insurance or is covered in an amount less than the amount required by the
Flood Disaster Protection Act of 1973, as amended, the Servicer shall notify
the related Mortgagor that the Mortgagor must obtain such flood insurance
coverage, and if said Mortgagor fails to obtain the required flood insurance
coverage within [thirty] days after such notification, the Servicer shall
immediately force place the required flood insurance on the Mortgagor's
behalf.

            The Servicer shall cause to be maintained on each Mortgaged
Property such other or additional insurance as may be required pursuant to
such applicable laws and regulations as shall at any time be in force and as
shall require such additional insurance, or pursuant to the requirements of
any private mortgage guaranty insurer, or as may be required to conform with
the Servicing Standard.

            In the event that the Master Servicer or the Servicer shall
determine that the Mortgaged Property should be insured against loss or damage
by hazards and risks not covered by the insurance required to be maintained by
the Mortgagor pursuant to the terms of the Mortgage, the Servicer shall
communicate and consult with the Mortgagor with respect to the need for such
insurance and bring to the Mortgagor's attention the desirability of
protection of the Mortgaged Property.

            All policies required hereunder shall name the Servicer as loss
payee and shall be endorsed with standard or union mortgagee clauses, without
contribution, which shall provide for at least [30] days' prior written notice
of any cancellation, reduction in amount or material change in coverage.

            The Servicer shall not interfere with the Mortgagor's freedom of
choice in selecting either his insurance carrier or agent; provided, however,
that the Servicer shall not accept any such insurance policies from insurance
companies unless such companies are generally acceptable under the Servicing
Standard. The Servicer shall determine that such policies provide sufficient
risk coverage and amounts, that they insure the property owner, and that they
properly describe the property address. The Servicer shall notify the
Mortgagor of the expiration of any such insurance and, prior to force placing
any insurance, will permit the Mortgagor a grace period (not to exceed [60]
days) to obtain renewal coverage.

            Pursuant to Section 4.02(d), any amounts collected by the Servicer
under any such policies (other than amounts to be deposited in the Escrow
Account and applied to the restoration or repair of the related Mortgaged
Property, or property acquired in liquidation of the Mortgage Loan, or to be
released to the Mortgagor, in accordance with the Servicer's normal servicing
procedures) shall be deposited in the Custodial Account subject to withdrawal
pursuant to Section 4.02(e).

      (l) Maintenance of Mortgage Impairment Insurance. In the event that the
Servicer shall obtain and maintain a blanket policy insuring against losses
arising from fire and hazards covered under extended coverage on all of the
Mortgage Loans, then, to the extent such policy provides coverage in an amount
equal to the amount required pursuant to Section 4.02(k) and otherwise
complies with all other requirements of Section 4.02(k), it shall conclusively
be

                                      72
<PAGE>

deemed to have satisfied its obligations as set forth in Section 4.02(k). Any
amounts collected by the Servicer under any such policy relating to a Mortgage
Loan shall be deposited in the Custodial Account subject to withdrawal
pursuant to Section 4.02(e). Such policy may contain a deductible clause, in
which case, in the event that there shall not have been maintained on the
related Mortgaged Property a policy complying with Section 4.02(k), and there
shall have been a loss which would have been covered by such policy, the
Servicer shall deposit in the Custodial Account at the time of such loss the
amount not otherwise payable under the blanket policy because of such
deductible clause, such amount to deposited from the Servicer's funds, without
reimbursement therefor. Upon request of the Master Servicer or the Indenture
Trustee, the Servicer shall cause to be delivered to such person a certified
true copy of such policy and a statement from the insurer thereunder that such
policy shall in no event be terminated or materially modified without [30]
days' prior written notice to the Master Servicer and the Indenture Trustee.

      (m) Maintenance of Fidelity Bond and Errors and Omissions Insurance. The
Servicer shall maintain with responsible companies, at its own expense, a
blanket Fidelity Bond and an Errors and Omissions Insurance Policy, with broad
coverage on all officers, employees or other persons acting in any capacity
requiring such persons to handle funds, money, documents or papers relating to
the Mortgage Loans ("Servicer Employees"). Any such Fidelity Bond and Errors
and Omissions Insurance Policy shall be in the form of the Mortgage Banker's
Blanket Bond and shall protect and insure the Servicer against losses,
including forgery, theft, embezzlement, fraud, errors and omissions and
negligent acts of such Servicer Employees. Such Fidelity Bond and Errors and
Omissions Insurance Policy also shall protect and insure the Servicer against
losses in connection with the release or satisfaction of a Mortgage Loan
without having obtained payment in full of the indebtedness secured thereby.
No provision of this Section 4.02(m) requiring such Fidelity Bond and Errors
and Omissions Insurance Policy shall diminish or relieve the Servicer from its
duties and obligations as set forth in this Agreement. The minimum coverage
under any such bond and insurance policy shall be at least equal to the
coverage amounts which are acceptable for the Servicer as determined by Fannie
Mae and Freddie Mac. Upon the request of the Master Servicer or the Indenture
Trustee, the Servicer shall cause to be delivered to such party a certified
true copy of such fidelity bond and insurance policy and a statement from the
surety and the insurer that such fidelity bond and insurance policy shall in
no event be terminated or materially modified without [30] days' prior written
notice to the Master Servicer and the Indenture Trustee.

      (n) Inspections. The Servicer shall inspect the Mortgaged Property as
often as deemed necessary by the Servicer to assure itself that the value of
the Mortgaged Property is being preserved. In addition, the Servicer shall
inspect the Mortgaged Property and/or take such other actions as may be
necessary or appropriate in accordance with the Servicing Standard or as may
be required by the primary mortgage guaranty insurer. The Servicer shall keep
a written report of each such inspection.

      (o) Restoration of Mortgaged Property. The Servicer need not obtain the
approval of the Master Servicer or the Indenture Trustee prior to releasing
any Insurance Proceeds or Condemnation Proceeds to the Mortgagor to be applied
to the restoration or repair of the Mortgaged Property if such release is in
accordance with the Servicing Standard. At a minimum,

                                      73
<PAGE>

the Servicer shall comply with the following conditions in connection with any
such release of Insurance Proceeds or Condemnation Proceeds:

            (i) the Servicer shall receive satisfactory independent
      verification of completion of repairs and issuance of any required
      approvals with respect thereto;

            (ii) the Servicer shall take all steps necessary to preserve the
      priority of the lien of the Mortgage, including, but not limited to
      requiring waivers with respect to mechanics' and materialmen's liens;
      and

            (iii) pending repairs or restoration, the Servicer shall place the
      Insurance Proceeds or Condemnation Proceeds in the Escrow Account.

      (p) Title, Management and Disposition of REO Property. In the event that
title to any Mortgaged Property is acquired in foreclosure or by deed in lieu
of foreclosure, the deed or certificate of sale shall be taken in the name of
the Indenture Trustee or its nominee (which shall include the Servicer) in
trust for the benefit of the Noteholders, or in the event the Indenture
Trustee is not authorized or permitted to hold title to real property in the
state where the REO Property is located, or would be adversely affected under
the "doing business" or tax laws of such state by so holding title, the deed
or certificate of sale shall be taken in the name of such Person or Persons as
shall be consistent with an Opinion of Counsel obtained by the Servicer (with
a copy delivered to the Indenture Trustee) from any attorney duly licensed to
practice law in the state where the REO Property is located. The Person or
Persons holding such title other than the Indenture Trustee shall acknowledge
in writing that such title is being held as nominee for the Indenture Trustee.

            The Servicer shall manage, conserve, protect and operate each REO
Property for the Indenture Trustee solely for the purpose of its prompt
disposition and sale. The Servicer, either itself or through an agent selected
by the Servicer, shall manage, conserve, protect and operate the REO Property
in the same manner that it manages, conserves, protects and operates other
foreclosed property for its own account, and in the same manner that similar
property in the same locality as the REO Property is managed. The Servicer
shall attempt to sell the same (and may temporarily rent the same for a period
not greater than one year, except as otherwise provided below) on such terms
and conditions as the Servicer deems to be in the best interest of the Issuer,
the Indenture Trustee and the Noteholders.

            If the Servicer hereafter becomes aware that a Mortgaged Property
is an Environmental Problem Property, the Servicer will notify the Master
Servicer of the existence of the Environmental Problem Property. Additionally,
the Servicer shall set forth in such notice a description of such problem, a
recommendation to the Master Servicer relating to the proposed action
regarding the Environmental Problem Property, and the Servicer shall carry out
the recommendation set forth in such notice. Notwithstanding the foregoing,
the Servicer shall obtain the Master Servicer's prior written consent to any
expenditures proposed to remediate Environmental Problem Properties or to
defend any claims associated with Environmental Problem Properties if such
expenses, in the aggregate, are expected to exceed $[100,000]. Failure to
provide written notice of disapproval of the expenditure within [five]
Business Days of receipt of such request for prepaid expenditures shall be
deemed an approval of such

                                      74
<PAGE>

expenditure. If the Servicer has received reliable instructions to the effect
that a Mortgaged Property is an Environmental Problem Property (e.g., Servicer
obtains a broker's price opinion which reveals the potential for such
problem), the Servicer will not accept a deed-in-lieu of foreclosure upon any
such Mortgaged Property without first obtaining a preliminary environmental
investigation for that Mortgaged Property.

            The Servicer shall also maintain on each REO Property fire and
hazard insurance with extended coverage in amount which is at least equal to
the maximum insurable value of the improvements which are a part of such
property and, to the extent required and available under the Flood Disaster
Protection Act of 1973, as amended, flood insurance in the amount required
above, which may be in the form of a blanket policy. Any amounts collected by
the Servicer under any such policy relating to a Mortgage Loan shall be
deposited in the Custodial Account subject to withdrawal pursuant to Section
4.02(e). Such policy may contain a deductible clause, in which case, in the
event that there shall not have been maintained on the related Mortgaged
Property a policy complying with Section 4.02(k), and there shall have been a
loss which would have been covered by such policy, the Servicer shall deposit
in the Custodial Account at the time of such loss the amount not otherwise
payable under the blanket policy because of such deductible clause, such
amount to deposited from the Servicer's funds, without reimbursement therefor.

            The proceeds of sale of the REO Property shall be promptly
deposited in the Custodial Account. As soon as practical thereafter the
expenses of such sale shall be paid and the Servicer shall reimburse itself
pursuant to Section 4.02(e) for any related unreimbursed Servicing Advances,
unpaid Servicing Fees and unreimbursed advances made pursuant to this Section
or Section 4.03.

            The Servicer shall make Servicing Advances of all funds necessary
for the proper operation, management and maintenance of the REO Property,
including the cost of maintaining any hazard insurance pursuant to Section
4.02(k), such advances to be reimbursed from the disposition or liquidation
proceeds of the REO Property or pursuant to Section 4.02(e)(4). The Servicer
shall make monthly remittances on each Servicer Remittance Date to the Master
Servicer of the net cash flow from the REO Property (which shall equal the
revenues from such REO Property net of the expenses described in this Section
4.02(p) and of any reserves reasonably required from time to time to be
maintained to satisfy anticipated liabilities for such expenses).

      (q) Real Estate Owned Reports. Together with the statement furnished
pursuant to Section 4.03(b), the Servicer shall furnish to the Master Servicer
on or before the [18th] calendar day in each month a statement with respect to
any REO Property covering the operation of such REO Property for the previous
month and the Servicer's efforts in connection with the sale of such REO
Property and any rental of such REO Property incidental to the sale thereof
for the previous month. That statement shall be accompanied by such other
information as the Master Servicer shall reasonably request.

      (r) Liquidation Reports. Upon the foreclosure sale of any Mortgaged
Property or the acquisition thereof by the Indenture Trustee pursuant to a
deed in lieu of foreclosure, the Servicer

                                      75
<PAGE>

shall submit to the Indenture Trustee and the Master Servicer a monthly
liquidation report with respect to such Mortgaged Property.

      (s) Reports of Foreclosures and Abandonments of Mortgaged Property.
Following the foreclosure sale or abandonment of any Mortgaged Property, the
Servicer shall report such foreclosure or abandonment as required pursuant to
Section 6050J of the Code.

      (t) Prepayment Premiums. The Servicer or any designee of the Servicer
shall not waive any Prepayment Premium with respect to any Mortgage Loan that
contains a Prepayment Premium and that prepays during the term of the premium.
If the Servicer or its designee fails to collect the Prepayment Premium upon
any prepayment of any Mortgage Loan that contains a Prepayment Premium, the
Servicer shall pay to the Master Servicer or the Trust Administrator at such
time (by deposit to the Custodial Account) an amount equal to amount of the
Prepayment Premium that was not collected. Notwithstanding the above, the
Servicer or its designee may waive a Prepayment Premium without paying the
Issuer the amount of the Prepayment Premium if (i) the Mortgage Loan is in
default (defined as [61] days or more delinquent) and such waiver would
maximize recovery of total proceeds taking into account the value of such
Prepayment Premium and the related Mortgage Loan or (ii) if the prepayment is
not a result of a refinancing by the Servicer or any of its affiliates and the
Mortgage Loan is foreseen to be in default and such waiver would maximize
recovery of total proceeds taking into account the value of such Prepayment
Premium and the related Mortgage Loan or (iii) the collection of the
Prepayment Premium would be in violation of applicable federal, state or local
laws or would be deemed "predatory" thereunder.

      (u) Compliance with Safeguarding Customer Information Requirements. The
Servicer has implemented and will maintain security measures designed to meet
the objectives of the Interagency Guidelines Establishing Standards for
Safeguarding Customer Information published in final form on February 1, 2001,
66 Fed. Reg. 8616, and the rules promulgated thereunder, as amended from time
to time (the "Guidelines").

      (v) Presentment of Claims and Collection of Proceeds. The Servicer shall
prepare and present on behalf of the Indenture Trustee and the Noteholders all
claims under the Insurance Policies with respect to the Mortgage Loans, and
take such actions (including the negotiation, settlement, compromise or
enforcement of the insured's claim) as shall be necessary to realize recovery
under such policies. Any proceeds disbursed to the Servicer in respect of such
policies or bonds shall be promptly deposited in the Custodial Account upon
receipt, except that any amounts realized that are to be applied to the repair
or restoration of the related Mortgaged Property as a condition requisite to
the presentation of claims on the related Mortgage Loan to the insurer under
any applicable Insurance Policy need not be so deposited (or remitted).

      (w) Purchase of Defaulted Mortgage Loans. The Servicer, in its sole
discretion, shall have the right to elect (by written notice sent to the
Indenture Trustee and the Trust Administrator) to purchase for its own account
from the Trust Estate any Mortgage Loan that is [90] days or more Delinquent
at a price equal to the Purchase Price; provided, however, that the Servicer
may only exercise this right on or after the last day of the calendar month in
which such Mortgage Loan became [90] days Delinquent (such month, the
"Eligible Purchase Month"); provided further, that any such Mortgage Loan
which becomes current but thereafter becomes

                                      76
<PAGE>

Delinquent may only be purchased by the Servicer pursuant to this Section
4.02(w) in any ensuing Eligible Purchase Month. The principal portion of the
funds in respect of such purchase of a Mortgage Loan will be considered a
Principal Prepayment and the Purchase Price shall be deposited in the
Collection Account. Upon receipt by the Trust Administrator of the full amount
of the Purchase Price for such Mortgage Loan and notification thereof has been
made to the Indenture Trustee, the Indenture Trustee shall release or cause to
be released and reassign to the Servicer the related Mortgage File for such
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 such Mortgage Loan released pursuant hereto, free and clear of all
security interests, liens and other encumbrances created by this Agreement and
the Indenture, which instruments shall be prepared by the Servicer and the
Indenture Trustee shall have no further responsibility with respect to the
Mortgage File relating to such [90] days Delinquent Mortgage Loan purchased by
the Seller.

      Section 4.03. Payments To the Master Servicer.

      (a) Remittances. On each Servicer Remittance Date, the Servicer shall
remit on a scheduled/scheduled basis by wire transfer of immediately available
funds to the Master Servicer (a) all amounts deposited in the Custodial
Account as of the close of business on the last day of the related Collection
Period (net of charges against or withdrawals from the Custodial Account
pursuant to Section 4.02(e)), plus (b) all Advances, if any, which the
Servicer is obligated to make pursuant to Section 4.03(c), minus (c) any
amounts attributable to Principal Prepayments, Liquidation Proceeds, Insurance
Proceeds, Condemnation Proceeds or REO Disposition Proceeds received after the
applicable Prepayment Period, which amounts shall be remitted on the following
Servicer Remittance Date, together with any Compensating Interest required to
be deposited in the Custodial Account in accordance with Section
4.02(d)(ii)(6) and Section 4.04(c), and minus (d) any amounts attributable to
Scheduled Payments collected but due on a Due Date or Due Dates subsequent to
the first day of the month in which such Servicer Remittance Date occurs,
which amounts shall be remitted on the Servicer Remittance Date next
succeeding the Due Date related to such Scheduled Payment.

            With respect to any remittance received by the Master Servicer
after the Servicer Remittance Date on which such remittance was due as
provided above, the Servicer shall pay to the Master Servicer interest on any
such late remittance at an annual rate equal to the Prime Rate, adjusted as of
the date of each change, plus three percentage points, but in no event greater
than the maximum amount permitted by applicable law. Such interest shall be
deposited in the Custodial Account by the Servicer on the date such late
remittance is made and shall cover the period commencing with the day
following such Servicer Remittance Date and ending with the Business Day on
which such remittance is made, both inclusive. The payment by the Servicer of
any such interest shall not be deemed an extension of time for payment or a
waiver of any Servicer Event of Default by the Servicer.

            All remittances required to be made to the Master Servicer shall
be made to the following wire account or to such other account as may be
specified by the Master Servicer from time to time:

                                      77
<PAGE>

            ____________________

            Account Name:  ___________________
            Account Number:  __________
            Reference:  ____________________

      (b) Statements to Master Servicer and Trust Administrator. On the [18th]
day of each calendar month (or, if such [18th] day is not a Business Day, then
no later than noon (Eastern Time) on the immediately preceding Business Day),
the Servicer shall furnish to the Master Servicer (i) a monthly remittance
advice in the format set forth in Exhibit G-1 hereto (including the
information in Exhibit G-1A), a monthly defaulted loan report in the format
set forth in Exhibit G-2 hereto (or in such other format mutually agreed to
between the Servicer and the Master Servicer) and, with respect to each
Mortgage Loan with respect to which a Realized Loss occurred during the
immediately preceding calendar month, a realized loss report in the format set
forth in Exhibit G-3 hereto (or in such other format mutually agreed to
between the Servicer and the Master Servicer), in each case relating to the
period ending on the last day of the preceding calendar month and (ii) all
such information required pursuant to clause (i) above on a magnetic tape or
other similar media reasonably acceptable to the Master Servicer. No later
than [two] Business Days after the end of each Prepayment Period, the Servicer
shall furnish to the Master Servicer a monthly report containing such
information regarding prepayments of Mortgage Loans during such Prepayment
Period and in a format as mutually agreed to between the Servicer and the
Master Servicer.

            Such monthly remittance advice shall also be accompanied by a
supplemental report provided to the Master Servicer and the Seller which
includes on an aggregate basis for the previous calendar month (i) the amount
of any insurance claims filed, (ii) the amount of any claim payments made and
(iii) the amount of claims denied or curtailed. The Master Servicer will
convert such data into a format acceptable to the Trust Administrator and
provide monthly reports to the Trust Administrator pursuant to the Trust
Agreement.

            In addition, not more than [75] days after the end of each
calendar year, commencing December 31, 200_, the Servicer shall provide (as
such information becomes reasonably available to the Servicer) to the Master
Servicer and the Trust Administrator such information concerning the Mortgage
Loans and annual remittances to the Master Servicer therefrom as is necessary
for the Trust Administrator to prepare the reports required by Section
5.09(c). Such obligation of the Servicer shall be deemed to have been
satisfied to the extent that substantially comparable information shall be
provided by the Servicer to the Master Servicer and the Trust Administrator
pursuant to any requirements of the Code as from time to time are in force.
The Servicer shall also provide to the Trust Administrator such information as
may be requested by it and required for the completion of any tax reporting
responsibility of the Trust Administrator within such reasonable time frame as
shall enable the Trust Administrator to timely file each Schedule Q (or other
applicable tax report or return) required to be filed by it.

      (c) Advances by Servicer. On the Business Day immediately preceding each
Servicer Remittance Date, the Servicer shall deposit in the Custodial Account
from its own funds or from amounts held for future payment, or a combination
of both, an amount equal to all

                                      78
<PAGE>

Advances for the related Servicer Remittance Date. Any amounts held for future
payment and so used shall be replaced by the Servicer by deposit in the
Custodial Account on or before any future Servicer Remittance Date if funds in
the Custodial Account on such Servicer Remittance Date shall be less than
remittances to the Master Servicer required to be made on such Servicer
Remittance Date. The Servicer shall keep appropriate records of such amounts
and will provide such records to the Master Servicer upon request.

            The Servicer's obligation to make such Advances as to any Mortgage
Loan will continue through the last Scheduled Payment due prior to the payment
in full of the Mortgage Loan, or through the last Remittance Date prior to the
Remittance Date for the payment of all Liquidation Proceeds and other payments
or recoveries (including Insurance Proceeds and Condemnation Proceeds) with
respect to the related Mortgage Loan.

      (d) Due Dates Other Than the First of the Month. Mortgage Loans having
Due Dates other than the first day of a month shall be accounted for as
described in this Section 4.03(d). Any Scheduled Payment due on a day other
than the first day of each month shall be considered due on the first day of
the month following the month in which that payment is due as if such payment
were due on the first day of that month. For example, a Scheduled Payment due
on August 15 shall be considered to be due on September 1. Any Scheduled
Payment due and collected on a Mortgage Loan after the Cut-off Date shall be
deposited in the Custodial Account. For Mortgage Loans with Due Dates on the
first day of a month, deposits to the Custodial Account begin with the
Scheduled Payment due on the first of the month following the Cut-off Date.

      (e) Credit Reporting. For each Mortgage Loan, in accordance with its
current servicing practices, the Servicer will accurately and fully report its
underlying borrower credit files to each of the following credit repositories
or their successors: Equifax Credit Information Services, Inc., Trans Union,
LLC and Experian Information Solution, Inc., on a monthly basis in a timely
manner.

      Section 4.04. General Servicing Procedures.

      (a) Transfers of Mortgaged Property. The Servicer shall use its best
efforts to enforce any "due-on-sale" provision contained in any Mortgage or
Mortgage Note and to deny assumption by the person to whom the Mortgaged
Property has been or is about to be sold whether by absolute conveyance or by
contract of sale, and whether or not the Mortgagor remains liable on the
Mortgage and the Mortgage Note. When the Mortgaged Property has been conveyed
by the Mortgagor, the Servicer shall, to the extent it has knowledge of such
conveyance, exercise its rights to accelerate the maturity of such Mortgage
Loan under the "due-on-sale" clause applicable thereto; provided, however,
that the Servicer shall not exercise such rights if prohibited by law from
doing so.

            If the Servicer reasonably believes it is unable under applicable
law to enforce such "due-on-sale" clause, the Servicer shall enter into (i) an
assumption and modification agreement with the person to whom such property
has been conveyed pursuant to which such person becomes liable under the
Mortgage Note and the original Mortgagor remains liable thereon or (ii) in the
event the Servicer is unable under applicable law to require that the original

                                      79
<PAGE>

Mortgagor remain liable under the Mortgage Note and the Servicer has the prior
consent of the primary mortgage guaranty insurer, a substitution of liability
agreement with the seller of the Mortgaged Property pursuant to which the
original Mortgagor is released from liability and the buyer of the Mortgaged
Property is substituted as Mortgagor and becomes liable under the Mortgage
Note. In connection with any such assumption, neither the Mortgage Rate borne
by the related Mortgage Note, the timing of principal or interest payments on
the Mortgage Loan, the term of the Mortgage Loan nor the outstanding principal
amount of the Mortgage Loan shall be changed.

            To the extent that any Mortgage Loan is assumable, the Servicer
shall inquire diligently into the creditworthiness of the proposed transferee,
and shall use the underwriting criteria for approving the credit of the
proposed transferee which are used by the Servicer, its affiliates or Fannie
Mae with respect to underwriting mortgage loans of the same type as the
Mortgage Loans. If the credit of the proposed transferee does not meet such
underwriting criteria, the Servicer diligently shall, to the extent permitted
by the Mortgage or the Mortgage Note and by applicable law, accelerate the
maturity of the Mortgage Loan.

            Notwithstanding the foregoing paragraph or any other provision of
this Agreement, the Servicer shall not be deemed to be in default, breach or
any other violation of its obligations hereunder by reason of any assumption
of a Mortgage Loan by operation of law or any assumption which the Servicer
may be restricted by law from preventing, for any reason whatsoever.

      (b) Satisfaction of Mortgages and 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 shall notify the Master Servicer in the monthly
remittance advice as provided in Section 4.03(b), and may request the release
of any Mortgage Loan Documents from the Custodian in accordance with the
Custodial Agreement.

            If the Servicer satisfies or releases a Mortgage without first
having obtained payment in full of the indebtedness secured by the Mortgage,
the Servicer shall deposit into the Custodial Account the entire outstanding
principal balance, plus all accrued interest on such Mortgage Loan, on the day
preceding the Servicer Remittance Date in the month following the date of such
release. The Servicer shall maintain the Fidelity Bond and Errors and
Omissions Insurance Policy as provided for in Section 4.02(m) insuring the
Servicer against any loss it may sustain with respect to any Mortgage Loan not
satisfied in accordance with the procedures set forth herein.

      (c) Servicing Compensation. As consideration for servicing the Mortgage
Loans subject to this Agreement, the Servicer shall be paid in the aggregate
the relevant Servicing Fee for each Mortgage Loan remaining subject to this
Agreement during any month or part thereof. Such Servicing Fee shall be
payable monthly and retained by the Servicer, or as otherwise provided in
Section 4.02(e)(2). The obligation of the Issuer to pay the Servicing Fee is
limited to, and the Servicing Fee is payable from, the interest portion
(including recoveries with respect to interest from Liquidation Proceeds) of
such Scheduled Payment collected by the Servicer, or as otherwise provided in
Section 4.02(e)(2). Additional servicing compensation in the form of

                                      80
<PAGE>

Ancillary Income shall be retained by the Servicer and is not required to be
deposited in the Custodial Account.

            The Servicer shall be required to pay all expenses incurred by it
in connection with its servicing activities hereunder and shall not be
entitled to reimbursement thereof except as specifically provided for herein.

            The Servicing Fee payable to or retained by the Servicer with
respect to any Collection Period shall be reduced by the aggregate Prepayment
Interest Shortfall Amount for the related Prepayment Period required to be
deposited in the Custodial Account and remitted to the Master Servicer on the
related Servicer Remittance Date. The Servicer shall be obligated to remit to
the Master Servicer on each Servicer Remittance Date the aggregate Prepayment
Interest Shortfall Amount, only up to an amount equal to in the aggregate the
Servicing Fee the Servicer is entitled to receive for such Collection Period.

      (d) [Reserved]

      (e) Annual Compliance Certifications.

            (i) No later than March 15 of each calendar year, commencing with
      the year 200_, the Servicer shall, and shall cause each Subservicer to,
      at its own expense, deliver to the Depositor, the Seller, the Master
      Servicer, the Indenture Trustee and the Trust Administrator a servicer's
      certificate stating, as to each signer thereof, that (i) a review of the
      activities of such Person during such preceding fiscal year (or
      applicable portion thereof) and of performance of such Person under this
      Agreement, or in the case of a Subservicer the applicable Subservicing
      Agreement or primary servicing agreement, has been made under such
      officers' supervision, and (ii) to the best of such officers' knowledge,
      based on such review, such Person has fulfilled all its obligations
      under this Agreement, or in the case of a Subservicer the applicable
      Subservicing Agreement or primary servicing agreement, in all material
      respects throughout such year (or applicable portion thereof), or, if
      there has been a failure to fulfill any such obligation in any material
      respect, specifying each such default known to such officers and the
      nature and status thereof including the steps being taken by the
      Servicer or Subservicer to remedy such default.

            (ii) The Servicer shall indemnify and hold harmless the Issuer,
      the Depositor, the Indenture Trustee, the Owner Trustee, the Trust
      Administrator and the Master Servicer and their respective 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 Servicer or any of its officers, directors, agents or
      affiliates of its obligations under this Section 4.04(e) for 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 any of the foregoing
      parties, then the Servicer agrees that it shall contribute to the amount
      paid or payable by the indemnified party or parties as a result of the
      losses, claims, damages or liabilities of the indemnified party or
      parties in such proportion as is appropriate to reflect the relative
      fault of the indemnified party or

                                      81
<PAGE>

      parties on the one hand and the Servicer on the other in connection with
      a breach of the Servicer's obligations under this Section 4.04(e) or the
      Servicer's negligence, bad faith or willful misconduct in connection
      therewith.

      (f) Inspection. The Servicer shall provide the Indenture Trustee and the
Master Servicer, upon [five] Business Days' advance notice, during normal
business hours, access to all records maintained by the Servicer in respect of
its rights and obligations hereunder and reasonable access to officers of the
Servicer responsible for such obligations. Upon request, the Servicer shall
furnish to the Indenture Trustee and the Master Servicer its most recent
publicly available financial statements and such other information relating to
its capacity to perform its obligations under this Agreement. Notwithstanding
anything to the contrary in this Section 4.04, nothing in this Agreement 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 4.04(f) as a result of
such obligation shall not constitute a breach of this Section 4.04(f).

      Section 4.05. Representations, Warranties and Agreements.

      (a) Representations, Warranties and Agreements of the Servicer. The
Servicer, as a condition to the consummation of the transactions contemplated
hereby, hereby makes the following representations and warranties to the
Master Servicer, the Depositor, the Seller and the Indenture Trustee and the
Trust Administrator, as of the Closing Date:

            (i) Due Organization and Authority. The Servicer is a corporation
      duly organized, validly existing and in good standing under the laws of
      the jurisdiction of its formation and has all licenses necessary to
      carry on its business as now being conducted; the Servicer has the full
      corporate power and authority to execute and deliver this Agreement and
      to perform in accordance herewith; the execution, delivery and
      performance of this Agreement (including all instruments of transfer to
      be delivered pursuant to this Agreement) by the Servicer and the
      consummation of the transactions contemplated hereby have been duly and
      validly authorized; this Agreement evidences the valid, binding and
      enforceable obligation of the Servicer (except to the extent bankruptcy,
      insolvency, reorganization, fraudulent conveyance or similar laws affect
      the enforcement of creditor's rights generally) and all requisite
      corporate action has been taken by the Servicer to make this Agreement
      valid and binding upon the Servicer in accordance with its terms;

            (ii) Ordinary Course of Business. The consummation of the
      transactions contemplated by this Agreement are in the ordinary course
      of business of the Servicer;

            (iii) No Conflicts. Neither the execution and delivery of this
      Agreement, the acquisition of the servicing responsibilities by the
      Servicer or the transactions contemplated hereby, nor the fulfillment of
      or compliance with the terms and conditions of this Agreement, will (a)
      conflict with or result in a breach of any of the terms, conditions or
      provisions of the Servicer's charter or by-laws or any legal restriction
      or constitute a default under any of the foregoing, (b) materially
      conflict with, result in a material breach, violation or acceleration
      of, or result in a material default under, the

                                      82
<PAGE>

      terms of any other agreement or instrument to which the Servicer is a
      party or by which it may be bound, (c) result in a material violation of
      any law, rule, regulation, order, judgment or decree to which the
      Servicer or its property is subject or (d) materially impair the ability
      of the Servicer to act as Servicer hereunder with respect to the
      Mortgage Loans;

            (iv) Ability to Perform. The Servicer does not believe, nor does
      it have any reason or cause to believe, that it cannot perform each and
      every covenant contained in this Agreement;

            (v) No Litigation Pending. There is no action, suit, proceeding or
      investigation pending or, to the Servicer's knowledge, threatened
      against the Servicer which, either in any one instance or in the
      aggregate, may result in any material adverse change in the business,
      operations, financial condition, properties or assets of the Servicer,
      or in any material impairment of the right or ability of the Servicer to
      carry on its business substantially as now conducted, or in any material
      liability on the part of the Servicer, or which would draw into question
      the validity of this Agreement or of any action taken or to be taken in
      connection with the obligations of the Servicer contemplated herein, or
      which would be likely to impair materially the ability of the Servicer
      to perform under the terms of this Agreement;

            (vi) No Consent Required. 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 if required, such approval has been
      obtained prior to the Closing Date;

            (vii) No Default. The Servicer is not in default, and no event or
      condition exists that after the giving of notice or lapse of time or
      both, would constitute an event of default under any material mortgage,
      indenture, contract, agreement, judgment, or other undertaking, to which
      the Servicer is a party or which purports to be binding upon it or upon
      any of its assets, which default could impair materially the ability of
      the Servicer to perform under the terms of this Agreement;

            (viii) Ability to Service. The Servicer is an FHA Approved
      Mortgagee in good standing to service mortgages, and has not been
      suspended as a mortgagee or servicer by the FHA and has the facilities,
      procedures and experienced personnel necessary for the sound servicing
      of mortgage loans of the same type as the Mortgage Loans. No event has
      occurred, including but not limited to a change in insurance coverage,
      which would make the Servicer unable to comply with HUD, FHA eligibility
      requirements or which would require notification to any of HUD or FHA;

            (ix) No Untrue Information. Neither this Agreement nor any
      statement, report or other document furnished or to be furnished
      pursuant to this Agreement or in connection with the transactions
      contemplated hereby contains any untrue statement of a material fact or
      omits to state a material fact necessary to make the statements
      contained therein not misleading; and

                                      83
<PAGE>

            (x) No Commissions to Third Parties. The Servicer has not dealt
      with any broker or agent or anyone else who might be entitled to a fee
      or commission in connection with this transaction other than the Seller.

      (b) Remedies for Breach of Representations and Warranties of the
Servicer. It is understood and agreed that the representations and warranties
set forth in Sections 4.05(a) shall survive the engagement of the Servicer to
perform the servicing responsibilities as of the Closing Date hereunder and
the delivery of the Servicing Files to the Servicer and shall inure to the
benefit of the Master Servicer and the Indenture Trustee. Upon discovery by
the Servicer, the Master Servicer or the Indenture Trustee of a breach of any
of the foregoing representations and warranties which materially and adversely
affects the ability of the Servicer to perform its duties and obligations
under this Agreement or otherwise materially and adversely affects the value
of the Mortgage Loans, the Mortgaged Property or the priority of the security
interest on such Mortgaged Property or the interests of the Master Servicer or
the Indenture Trustee, the party discovering such breach shall give prompt
written notice to the other parties.

            Within [60] days of the earlier of either discovery by or notice
to the Servicer of any breach of a representation or warranty set forth in
Section 4.05(a) which materially and adversely affects the ability of the
Servicer to perform its duties and obligations under this Agreement or
otherwise materially and adversely affects the value of the Mortgage Loans,
the Mortgaged Property or the priority of the security interest on such
Mortgaged Property, the Servicer shall use its best efforts promptly to cure
such breach in all material respects and, if such breach cannot be cured, the
Servicer shall, at the Indenture Trustee's or the Master Servicer's option,
assign its rights and obligations under this Agreement (or with respect to the
affected Mortgage Loans) to a successor servicer. Such assignment shall be
made in accordance with Sections 4.06(b) and 4.06(c).

            In addition, the Servicer shall indemnify all other parties to
this Agreement and hold each of them harmless against any losses, damages,
penalties, fines, forfeitures, reasonable and necessary legal fees and related
costs, judgments, and other costs and expenses resulting from any claim,
demand, defense or assertion based on or grounded upon, or resulting from, a
breach of the Servicer's representations and warranties contained in Section
4.05.

            Any cause of action against the Servicer relating to or arising
out of the breach of any representations and warranties made in Section
4.05(a) shall accrue upon (i) discovery of such breach by the Servicer or
notice thereof by the Master Servicer, the Depositor or the Indenture Trustee
to the Servicer, (ii) failure by the Servicer to cure such breach within the
applicable cure period, and (iii) demand upon the Servicer by the Master
Servicer or the Indenture Trustee for compliance with this Agreement.

      (c) Additional Indemnification by the Servicer. The Servicer shall
indemnify the Master Servicer, the Depositor, the Issuer, the Indenture
Trustee, the Owner Trustee, and the Trust Administrator 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 (collectively, the "Liabilities") that
the indemnified party may sustain in any way related to the failure of the
Servicer to perform its duties and service the Mortgage Loans in accordance
with the terms of this Agreement. The Servicer shall immediately

                                      84
<PAGE>

notify the Master Servicer, the Depositor, the Indenture Trustee, the Owner
Trustee and the Trust Administrator if a claim is made by a third party with
respect to this Agreement or the Mortgage Loans that may result in such
Liabilities, and the Servicer shall assume (with the prior written consent of
the indemnified party) the defense of any such claim and pay all expenses in
connection therewith, including counsel fees, promptly pay, discharge and
satisfy any judgment or decree which may be entered against it or any
indemnified party in respect of such claim and follow any written instructions
received from such indemnified party in connection with such claim. The
Servicer shall be reimbursed promptly from the Trust Fund for all amounts
advanced by it pursuant to the preceding sentence except when the claim is in
any way related to the Servicer's indemnification pursuant to this Section
4.05(c), or the failure of the Servicer to service and administer the Mortgage
Loans in accordance with the terms of this Agreement.

      Section 4.06. The Servicer.

      (a) Merger or Consolidation of the Servicer. The Servicer shall keep in
full effect its existence, rights and franchises as a corporation, and shall
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 duties under this Agreement.

            Any Person into which the Servicer may be merged or consolidated,
or any corporation resulting from any merger, conversion or consolidation to
which the Servicer shall be a party, or any Person succeeding to the business
of the Servicer, shall be the successor of the Servicer 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, provided,
however, that the successor or surviving Person shall be an institution (i)
having a net worth of not less than $[15,000,000], and (ii) which is a FHA
Approved Mortgagee in good standing.

            As a condition to the effectiveness of any merger or
consolidation, at least 15 calendar days prior to the effective date of any
merger or consolidation of the Servicer, the Servicer shall provide (x)
written notice to the Depositor and the Master Servicer of any successor
pursuant to this Section and (y) in writing and in form and substance
reasonably satisfactory to the Depositor, all information reasonably requested
by the Depositor in order to comply with its reporting obligation under Item
6.02 of Form 8-K.

      (b) Limitation on Liability of the Servicer and Others. Neither the
Servicer nor any of the directors, officers, employees or agents of the
Servicer shall be under any liability to the Master Servicer, the Depositor,
the Issuer, the Indenture Trustee or the Trust Administrator 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 Servicer or any such person against any breach
of warranties or representations made herein, or failure to perform its
obligations in strict compliance with any standard of care set forth in this
Agreement, or any liability which would otherwise be imposed by reason of any
breach of the terms and conditions of this Agreement (except to the extent
otherwise covered by Section 4.05(c)). The Servicer and any director, officer,
employee or agent of 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 Servicer shall not be under any obligation

                                      85
<PAGE>

to appear in, prosecute or defend any legal action which is not incidental to
its duties to service the Mortgage Loans in accordance with this Agreement and
which in its opinion may involve it in any expense or liability; provided,
however, that the Servicer may undertake any such action which it may deem
necessary or desirable in respect of this Agreement and the rights and duties
of the parties hereto. In such event, the Servicer shall be entitled to
reimbursement from the Trust Fund for the reasonable legal expenses and costs
of such action.

            The Servicer and any director, officer, employee or agent of the
Servicer shall be indemnified and held harmless by the Trust against any and
all Liabilities incurred in connection with any legal action relating to this
Agreement or the Notes, except to the extent such Liabilities resulted from or
arose out of the negligence, bad faith or willful misfeasance in the
performance of the Servicer's (or any director, officer, employee or agent of
the Servicer) duties hereunder or by reason of its reckless disregard of its
obligations and duties hereunder.

      (c) Limitation on Resignation and Assignment by the Servicer. This
Agreement has been entered into with the Servicer in reliance upon the
independent status of the Servicer, and the representations as to the adequacy
of its servicing facilities, plant, personnel, records and procedures,
integrity, reputation and financial standing, and the continuance thereof.
Therefore, except as expressly provided in this Section 4.06(c) and in
Sections 4.02(a) and 4.09, the Servicer shall neither assign its rights under
this Agreement or the servicing hereunder nor delegate its duties hereunder or
any portion thereof, or sell or otherwise dispose of all or substantially all
of its property or assets without, in each case, the prior written consent of
the Seller, the Master Servicer and the Trust Administrator, which consent, in
the case of an assignment of rights or delegation of duties, shall be granted
or withheld in the discretion of the Seller, the Master Servicer and the Trust
Administrator; provided, that in each case, there must be delivered to the
Seller, the Master Servicer, the Indenture Trustee and the Trust Administrator
a letter from each Rating Agency to the effect that such transfer of servicing
or sale or disposition of assets will not result in a qualification,
withdrawal or downgrade of the then-current rating of any of the Notes.

            The Servicer shall not resign from the obligations and duties
hereby imposed on it except by mutual consent of the Servicer and the Master
Servicer, or upon the determination that its duties hereunder are no longer
permissible under applicable law and such incapacity cannot be cured by the
Servicer. Any such determination permitting the resignation of the Servicer
shall be evidenced by an Opinion of Counsel to such effect delivered to the
Seller, the Master Servicer and the Indenture Trustee which Opinion of Counsel
shall be in form and substance reasonably acceptable to each of them. No such
resignation shall become effective until a successor shall have assumed the
Servicer's responsibilities and obligations hereunder in the manner provided
in Section 4.08 and the Depositor shall have received the information
described in the following sentence. As a condition to the effectiveness of
any such resignation, at least 15 calendar days prior to the effective date of
such resignation, the Servicer shall provide (x) written notice to the
Depositor of any successor pursuant to this Section and (y) in writing and in
form and substance reasonably satisfactory to the Depositor, all information
reasonably requested by the Depositor in order to comply with its reporting
obligation under Item 6.02 of Form 8-K with respect to a successor Master
Servicer.

                                      86
<PAGE>

            Without in any way limiting the generality of this Section 4.06,
in the event that the Servicer either shall assign this Agreement or the
servicing responsibilities hereunder or delegate its duties hereunder or any
portion thereof or sell or otherwise dispose of all or substantially all of
its property or assets, except to the extent permitted by and in accordance
with this Section 4.06 and in Sections 4.02(a) and 4.09, without the prior
written consent of the Seller, the Master Servicer, the Indenture Trustee and
the Trust Administrator, then such parties shall have the right to terminate
this Agreement upon notice given as set forth in Section 4.07, without any
payment of any penalty or damages and without any liability whatsoever to the
Servicer or any third party.

      (d) Successor Servicers. The provisions of Sections 4.06(a), (b), and
(c) shall apply to any successor to the Servicer hereunder.

      Section 4.07. Termination for Cause.

            Any of the following occurrences shall constitute an event of
default (each, a "Servicer Event of Default") on the part of the Servicer:

                              (1) any failure by the Servicer to remit to the
                        Master Servicer any payment required to be made under
                        the terms of this Agreement which continues unremedied
                        for a period of [two] Business Days after the date
                        upon which written notice of such failure, requiring
                        the same to be remedied, shall have been given to the
                        Servicer by the Master Servicer; or

                              (2) failure by the Servicer duly to observe or
                        perform in any material respect any other of the
                        covenants or agreements on the part of the Servicer
                        set forth in this Agreement (except with respect to a
                        failure related to a Limited Exchange Act Reporting
                        Obligation) which continues unremedied for a period of
                        [30] days after the date on which written notice of
                        such failure, requiring the same to be remedied, shall
                        have been given to the Servicer by the Master
                        Servicer; provided that the [thirty-day] cure period
                        shall not apply to the failure to comply with the
                        requirements set forth in Section 4.04(e), Section
                        4.06(a) (with respect to notice to the Depositor),
                        Section 4.06(c) (with respect to notice to the
                        Depositor) or Article XI, for which the grace period
                        shall not exceed the lesser of 10 calendar days or
                        such period in which the applicable Exchange Act
                        Report can be filed timely (without taking into
                        account any extensions); or

                              (3) failure by the Servicer to maintain its
                        license to do business or service residential mortgage
                        loans in any jurisdiction where the Mortgaged
                        Properties are located except where the failure to so
                        maintain such license does not have a material adverse
                        effect on the Servicer's ability to service the
                        Mortgage Loans; or

                                      87
<PAGE>

                              (4) a decree or order of a court or agency or
                        supervisory authority having jurisdiction for the
                        appointment of a conservator or receiver or liquidator
                        in any insolvency, readjustment of debt, including
                        bankruptcy, marshalling 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] days; or

                              (5) the Servicer shall consent to the
                        appointment of a conservator or receiver or liquidator
                        in any insolvency, readjustment of debt, marshalling
                        of assets and liabilities or similar proceedings of or
                        relating to the Servicer or of or relating to all or
                        substantially all of its property; or

                              (6) the Servicer shall admit in writing its
                        inability to pay its debts generally as they become
                        due, file a petition to take advantage of any
                        applicable insolvency, bankruptcy or reorganization
                        statute, make an assignment for the benefit of its
                        creditors, voluntarily suspend payment of its
                        obligations or cease its normal business operations
                        for [three] Business Days; or

                              (7) the Servicer ceases to be a FHA Approved
                        Mortgagee; or

                              (8) the Servicer attempts to assign the
                        servicing of the Mortgage Loans or its right to
                        servicing compensation hereunder or the Servicer or
                        attempts to assign this Agreement or the servicing
                        responsibilities hereunder or to delegate its duties
                        hereunder or any portion thereof in a manner not
                        permitted under this Agreement; or

                              (9) the net worth of the Servicer shall be less
                        than $[15,000,000]; or

                              (10) failure by the Servicer to duly perform,
                        within the required time period, its obligations under
                        Section 4.04(e) or 4.04(d) which failure continues
                        unremedied for a period of [7] days after the date on
                        which written notice of such failure, requiring the
                        same to be remedied, shall have been given to the
                        Servicer by the Master Servicer.

            In each and every such case, so long as a Servicer Event of
Default shall not have been remedied, in addition to whatsoever rights the
Master Servicer or the Indenture Trustee may have at law or equity to damages,
including injunctive relief and specific performance, the Master Servicer, by
notice in writing to the Servicer and the Depositor, may terminate all the

                                      88
<PAGE>

rights and obligations of the Servicer under this Agreement and in and to the
servicing contract established hereby and the proceeds thereof; provided that
in the event of a Servicer Event of Default related to the obligations set
forth in Section 4.04(e), Section 4.06(a) (with respect to notice to the
Depositor), Section 4.06(c) (with respect to notice to the Depositor) and
Article XI, the Servicer may only be terminated at the direction of the
Depositor.

            Upon receipt by the Servicer of such written termination notice,
all authority and power of the Servicer, under this Agreement, whether with
respect to the Mortgage Loans or otherwise, shall pass to and be vested in a
successor servicer appointed by the Master Servicer, in accordance with
Section 4.08(a). Upon written request from the Master Servicer, the Servicer
shall prepare, execute and deliver to the successor servicer any and all
documents and other instruments, place in such successor's possession all
Servicing Files, and do or cause to be done all other acts or things necessary
or appropriate to effect the purposes of such notice of termination, including
but not limited to the transfer and endorsement or assignment of the Mortgage
Loans and related documents, at the Servicer's sole expense. The Servicer
shall cooperate with the Seller, the Master Servicer, the Indenture Trustee
and such successor in effecting the termination of the Servicer's
responsibilities and rights hereunder, including without limitation, the
transfer to such successor for administration by it of all cash amounts which
shall at the time be credited by the Servicer to the Custodial Account or
Escrow Account or thereafter received with respect to the Mortgage Loans.

            By a written notice, the Master Servicer may waive any default by
the Servicer in the performance of its obligations hereunder and its
consequences. Upon any waiver of a past default, such default shall cease to
exist, and any Servicer Event of Default arising therefrom shall be deemed to
have been remedied for every purpose of this Agreement. No such waiver shall
extend to any subsequent or other default or impair any right consequent
thereon except to the extent expressly so waived.

            The Depositor shall not be entitled to terminate the rights and
obligations of the Servicer pursuant to subparagraph (2) if a failure of the
Servicer to identify a Subcontractor "participating in the servicing function"
within the meaning of Item 1122 of Regulation AB was attributable solely to
the role or functions of such Subcontractor with respect to mortgage loans
other than the Mortgage Loans.

      Section 4.08. Successor to Servicer, Miscellaneous Provisions.

      (a) Successor to the Servicer. Simultaneously with the termination of
the Servicer's responsibilities and duties under this Agreement pursuant to
Section 4.05, 4.06, or 4.07, the Master Servicer shall (i) within [90] days of
the Servicer's notice of such termination, succeed to and assume all of the
Servicer's responsibilities, rights, duties and obligations under this
Agreement, or (ii) appoint a successor having the characteristics set forth in
clauses (i) and (ii) of the second paragraph of Section 4.06(a) and which
shall succeed to all rights and assume all of the responsibilities, duties and
liabilities of the Servicer under this Agreement simultaneously with the
termination of the Servicer's responsibilities, duties and liabilities under
this Agreement. Any successor to the Servicer (other than the Master Servicer)
shall be subject to the approval of the Master Servicer and the Trust
Administrator. Any approval of a successor servicer by the Master Servicer and
the Trust Administrator, shall, if the successor servicer is not at that time
a

                                      89
<PAGE>

servicer of other Mortgage Loans for the Trust, be conditioned upon the
receipt by the Master Servicer, the Seller, the Indenture Trustee and the
Trust Administrator of a letter from each Rating Agency to the effect that
such transfer of servicing will not result in a qualification, withdrawal or
downgrade of the then-current rating of any of the Notes. At least 15 calendar
days prior to the effective date of any such appointment, (x) the Master
Servicer shall provide written notice to the Depositor of such successor
pursuant to this Section 4.08 and (y) such successor servicer shall provide to
the Depositor in writing and in form and substance reasonably satisfactory to
the Depositor, all information reasonably requested by the Depositor in order
to comply with its reporting obligation under Item 6.02 of Form 8-K with
respect to a successor servicer. In the event that the Master Servicer assumes
the duties of the Servicer as set forth herein, the Master Servicer shall
provide the Depositor in writing and in form and substance reasonably
satisfactory to the Depositor, all information reasonably requested by the
Depositor in order to comply with its reporting obligation under Item 6.02 of
Form 8-K with respect to a successor servicer. In connection with such
appointment and assumption, the Master Servicer 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 under this Agreement. In the event
that the Servicer's duties, responsibilities and liabilities under this
Agreement should be terminated pursuant to the aforementioned sections, the
Servicer shall discharge such duties and responsibilities during the period
from the date it acquires knowledge of such termination until the effective
date thereof with the same degree of diligence and prudence which it is
obligated to exercise under this Agreement (including continuing to make
Advances during such transition period pursuant to Section 4.03(c)) and shall
take no action whatsoever that might impair or prejudice the rights or
financial condition of its successor. The resignation or removal of the
Servicer pursuant to the aforementioned sections shall not become effective
until a successor shall be appointed pursuant to this Section 4.08(a) and
shall in no event relieve the Servicer of the representations and warranties
made pursuant to Sections 4.05 and the remedies available to the Master
Servicer, the Indenture Trustee and the Seller under Sections 4.08(b) and
4.05(b) and (c), it being understood and agreed that the provisions of such
Sections 4.08(b) and 4.05(b) and (c) shall be applicable to the Servicer
notwithstanding any such resignation or termination of the Servicer, or the
termination of this Agreement. Neither the Master Servicer, in its capacity as
successor servicer, nor any other successor servicer shall be responsible for
the lack of information and/or documents that it cannot otherwise obtain
through reasonable efforts.

            Within a reasonable period of time, but in no event later than
[30] days following the appointment of a successor entity, the Servicer shall
prepare, execute and deliver to the successor entity any and all documents and
other instruments, place in such successor's possession all Servicing Files,
and do or cause to be done all other acts or things necessary or appropriate
to effect the purposes of such notice of termination, including but not
limited to the transfer of any Mortgage Notes and the related documents. The
Servicer shall cooperate with the Indenture Trustee, the Master Servicer or
the Seller, as applicable, and such successor in effecting the termination of
the Servicer's responsibilities and rights hereunder and the transfer of
servicing responsibilities to the successor Servicer, including without
limitation, the transfer to such successor for administration by it of all
cash amounts which shall at the time be credited by the Servicer to the
Custodial Account or Escrow Account or thereafter received with respect to the
Mortgage Loans.

                                      90
<PAGE>

            Any successor appointed as provided herein shall execute,
acknowledge and deliver to the Indenture Trustee, the Servicer, the Master
Servicer, the Trust Administrator and the Seller an instrument (i) accepting
such appointment, wherein the successor shall make the representations and
warranties set forth in Section 4.05(a) and provide for the same remedies set
forth in such Section herein and (ii) an assumption of the due and punctual
performance and observance of each covenant and condition to be performed and
observed by the Servicer under this Agreement, whereupon such successor shall
become fully vested with all the rights, powers, duties, responsibilities,
obligations and liabilities of the Servicer, with like effect as if originally
named as a party to this Agreement. Any termination or resignation of the
Servicer or termination of this Agreement pursuant to Sections 4.05, 4.06 and
4.07 shall not affect any claims that the Seller, the Master Servicer, the
Indenture Trustee or the Trust Administrator may have against the Servicer
arising out of the Servicer's actions or failure to act prior to any such
termination or resignation.

            The Servicer shall deliver promptly to the successor servicer the
funds in the Custodial Account and Escrow Account(s) and all Mortgage Loan
documents and related documents and statements held by it hereunder and the
Servicer shall account for all funds and shall execute and deliver such
instruments and do such other things as may reasonably be required to more
fully and definitively vest in the successor all such rights, powers, duties,
responsibilities, obligations and liabilities of the Servicer.

            Upon a successor's acceptance of appointment as such, it shall
notify the Indenture Trustee, the Trust Administrator, the Seller and Master
Servicer and the Depositor of such appointment.

      (b) Costs. The Seller shall pay the legal fees and expenses of its
attorneys. Costs and expenses incurred in connection with the transfer of the
servicing responsibilities, including fees for delivering Servicing Files,
shall be paid by (i) the terminated or resigning Servicer if such termination
or resignation is a result of an occurrence of a termination event under
Section 4.05(b) or 4.07, and (ii) to the extent not paid by such Servicer, and
in all other cases, by the Trust.

      Section 4.09. Sub-Servicers and Sub-Servicing Agreements.

      (a) The Servicer may enter into sub-servicing agreements for any
servicing and administration of Mortgage Loans with any institution that is
acceptable to the Seller and that is in compliance with the laws of each state
necessary to enable it to perform its obligations under such sub-servicing
agreement. The Servicer shall give notice to the Rating Agencies and the
Master Servicer of the appointment of any sub-servicer. The Servicer shall not
enter into any sub-servicing agreement that does not provide for the servicing
of the Mortgage Loans specified therein on a basis consistent with the terms
of this Agreement or that otherwise violates the provisions of this Agreement.
The Servicer may enter into, and make amendments to, any sub-servicing
agreement or enter into different forms of sub-servicing agreements; provided,
however, that any such amendments or forms shall be consistent with and not
violate the provisions of this Agreement.

                                      91
<PAGE>

      (b) For purposes of this Agreement the Servicer shall be deemed to have
received payments on Mortgage Loans when any sub-servicer has received such
payments. With respect to the Servicer's obligations under Section 4.03(a) to
make deposits in the Custodial Account maintained by the Servicer, the
Servicer shall be deemed to have made such deposits when any sub-servicer has
made such deposits into a sub-servicing account if permitted by the related
sub-servicing agreement.

      (c) Any sub-servicing agreement and any other transactions or services
relating to the Mortgage Loans involving a sub-servicer shall be deemed to be
between the sub-servicer and the Servicer alone and the Master Servicer and
the Indenture Trustee shall not be deemed parties thereto and shall have no
claims, rights, obligations, duties or liabilities with respect to any
sub-servicer, except that the Indenture Trustee shall have such claims or
rights that arise as a result of any funds held by a sub-servicer in trust for
or on behalf of the Issuer. Notwithstanding the execution of any sub-servicing
agreement, the Servicer shall not be relieved of any liability hereunder and
shall remain obligated and liable for the servicing and administration of the
Mortgage Loans.

      (d) The Servicer shall be entitled to terminate any sub-servicing
agreement and the rights and obligations of any sub-servicer pursuant to any
sub-servicing agreement in accordance with the terms and conditions of such
sub-servicing agreement but only with the prior consent of the Seller. In the
event of termination of any sub-servicer, all servicing obligations of such
sub-servicer shall be assumed simultaneously by the Servicer without any act
or deed on the part of such sub-servicer or the Servicer, and the Servicer
either shall service directly the related Mortgage Loans or shall enter into a
sub-servicing agreement with a successor sub-servicer. The Servicer shall give
written notice to the Seller, Master Servicer and Indenture Trustee of the
termination of any sub-servicer.

      (e) Any sub-servicing agreement shall include the provision that such
agreement may be immediately terminated by the Master Servicer or the
Indenture Trustee, in accordance with the terms of this Agreement, in the
event that the Servicer shall, for any reason, no longer be the Servicer
(including termination due to a Servicer Event of Default) (i) without fee or
(ii) clearly and unambiguously states that any termination fee is the sole
responsibility of the Servicer and none of the Seller, Depositor, Master
Servicer, Indenture Trustee or the Issuer has any liability therefor,
regardless of the circumstances surrounding such termination.

      Section 4.10. Miscellaneous Servicing Provisions.

      (a) Protection of Confidential Information. The Servicer shall keep
confidential and shall not divulge to any party, without the Seller's prior
written consent, any nonpublic information pertaining to the Mortgage Loans or
any borrower thereunder, except to the extent that it is appropriate for the
Servicer to do so in working with legal counsel, special servicers, auditors,
taxing authorities or other governmental agencies.

      (b) No Personal Solicitation. For as long as the Servicer services the
Mortgage Loans, it 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 promotions

                                      92
<PAGE>

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 4.10(b).

      (c) Intention of the Parties. It is the intention of the Seller and the
Servicer that the Seller is conveying, and the Servicer is receiving, only a
contract for servicing the Mortgage Loans. Accordingly, the parties hereby
acknowledge that the Trust remains the sole and absolute owner of the Mortgage
Loans (other than the servicing rights) and all rights related thereto,
subject to the lien of the Indenture.

      Section 4.11. Advance Facility.

      (a) The Servicer is hereby authorized to enter into a facility (an
"Advance Facility") with any Person which provides that such Person (an
"Advancing Person") agrees to fund some or all of the Advances and/or
Servicing Advances required to be made by the Servicer pursuant to this
Agreement or that the Servicer may pledge or assign its rights to be
reimbursed for Advances and/or Servicing Advances, directly or indirectly, to
an Advancing Person, although no such Advance Facility shall reduce or
otherwise affect the Servicer's obligation to fund such Advances and/or
Servicing Advances. If the Servicer enters into an Advance Facility, the
Servicer and the related Advancing Person shall deliver to the Indenture
Trustee, the Master Servicer and the Trust Administrator at the respective
addresses set forth in Section 10.07 hereof a written notice (an "Advance
Facility Notice"), stating the identity of the Advancing Person. If the
Servicer enters into such an Advance Facility pursuant to this Section 4.11,
upon reasonable request of the Advancing Person, the Trust Administrator shall
execute a letter of acknowledgment prepared by the Servicer, confirming its
receipt of notice of the existence of such Advance Facility. To the extent
that an Advancing Person previously identified in the Advance Facility Notice
funds any Advance or any Servicing Advance and the Servicer provides the Trust
Administrator with an Officer's Certificate that such Advancing Person is
entitled to reimbursement, such Advancing Person shall be entitled to receive
reimbursement pursuant to this Agreement for such amount to the extent
provided in Section 4.11(c). Such Officer's Certificate must specify the
amount of the reimbursement, the remittance date, the written payment
instructions for the Advancing Person, the Section of this Agreement that
permits the applicable Advance or Servicing Advance to be reimbursed and
either the section(s) of the Advance Facility that entitle the Advancing
Person to receive reimbursement from the Trust Administrator, rather than the
Servicer, or proof of an event of default by the Servicer under the Advance
Facility entitling the Advancing Person to reimbursement from the Trust
Administrator. The Trust Administrator shall not have any duty or liability
with respect to any calculation of any reimbursement to be paid to an
Advancing Person and shall be entitled to conclusively rely without
independent investigation on the Officer's Certificate provided pursuant to
this Section 4.11. An Advancing Person whose obligations hereunder are limited
to the funding of Advances and/or Servicing Advances, or who merely receives
an assignment or pledge of the Servicer's rights to be reimbursed for Advances
and/or Servicing Advances, shall not be required to meet the qualifications of
the Servicer or any sub-servicer and will not be deemed to be a sub-servicer
under this Agreement.

      (b) None of the Depositor, the Master Servicer, the Trust Administrator
or the Indenture 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 reimbursement for Advances or

                                      93
<PAGE>

Servicing Advances, nor, as a result of the existence of any Advance Facility,
shall the Depositor, the Master Servicer, the Trust Administrator or the
Indenture Trustee have any additional responsibility to track or monitor the
administration of the Advance Facility or the reimbursement for Advances or
Servicing Advances, except, in the case of the Trust Administrator, to remit
reimbursements in accordance with payment instructions received pursuant to
Section 4.11(a). The Servicer shall indemnify the Depositor, the Master
Servicer, the Trust Administrator, the Indenture Trustee, any successor
Servicer and the Issuer for any claim, loss, liability or damage resulting
from any claim by the Advancing Person, except to the extent that such claim,
loss, liability or damage resulted from or arose out of the negligence,
recklessness or willful misconduct on the part of the Depositor, the Master
Servicer, the Trust Administrator, the Indenture Trustee, any successor
Servicer or the Issuer, as the case may be, or failure by the successor
Servicer, the Master Servicer or the Trust Administrator, as the case may be,
to remit funds as required by this Agreement or the commission of an act or
omission to act by the successor Servicer, the Master Servicer or the Trust
Administrator, as the case may be, and the passage of any applicable cure or
grace period, such that, in the case of the Master Servicer, a Master Servicer
Event of Default occurs under this Agreement, or in the case of the successor
Servicer, the Master Servicer or the Trust Administrator, such entity is
subject to termination for cause under this Agreement.

      (c) If an Advance Facility is entered into, and if the Servicer so
notifies the Trust Administrator, then the Servicer shall not seek
reimbursement for any Advance or Servicing Advance made by an Advancing Person
under Section 6.05, but instead the Servicer shall remit the amounts relating
to Advances to the Master Servicer for inclusion in the monthly remittance
made to the Trust Administrator on a Servicer Remittance Date in accordance
with this Agreement. The Trust Administrator, upon its receipt of an Officer's
Certificate in accordance with Section 4.11 hereof, shall pay to the Advancing
Person or to a trustee, agent or custodian designated in the Officer's
Certificate specified in Section 4.11(a), reimbursements for Advances and
Servicing Advances from the Collection Account to the same extent the Servicer
would have been permitted to reimburse itself from its Custodial Account for
such Advances and/or Servicing Advances in accordance with Sections 4.02(e)
and 6.05, had the Servicer itself funded such Advance or Servicing Advance.

      (d) All Advances and Servicing Advances made pursuant to the terms of
this Agreement shall be deemed made and shall be reimbursed on a "first
in-first out" (FIFO) basis, such that an advance made earlier in time with
respect to any Mortgage Loan shall be reimbursed to the Servicer who made that
advance, before reimbursement of an advance made later in time with respect to
that Mortgage Loan, and a predecessor Servicer's advances with respect to any
particular Mortgage Loan shall be reimbursed before reimbursement of a
successor Servicer's advances with respect to such Mortgage Loan.

      (e) In making its determination that any Advance or Servicing Advance
theretofore made has become a Nonrecoverable 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.

      (f) The Servicer shall maintain and provide to any successor Servicer
and, upon request, the Master Servicer, the Trust Administrator and the
Indenture Trustee a detailed

                                      94
<PAGE>

accounting on a loan-by-loan basis as to amounts advanced by, pledged or
assigned to, and reimbursed to any Advancing 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.

      (g) Any amendment to this Section 4.11 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 4.11, including
amendments to add provisions relating to a successor Servicer, may be entered
into by the parties hereto without the consent of any Noteholder, provided
that such amendment complies with Section 10.03. 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 Advancing 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 Indenture
Trustee, the Owner Trustee, the Trust Administrator, the Master Servicer and
the Issuer are not, as a result of the existence of any Advance Facility,
separately obligated or liable to repay any Advances and/or Servicing Advances
financed by the Advancing Person; (b) the Servicer will be responsible for
remitting to the Advancing Person the applicable amounts collected by it as
reimbursement for Advances and/or Servicing Advances funded by the Advancing
Person, subject to the provisions of this Agreement and except to the extent
an election is made to remit all such reimbursements to the Trust
Administrator as described in Section 4.11(c); and (c) none of the Master
Servicer, the Trust Administrator and the Indenture Trustee shall have any
responsibility to track or monitor the administration of the financing
arrangement between the Servicer and any Advancing Person.

      Servicer and its performance and compliance with the terms of this
      Agreement will not (A) violate the Master Servicer's charter or bylaws,

      to which it is subject or (C) constitute a default (or an event which,
      with notice or lapse of time, or both, would constitute a default)
      under, or result in the breach of, any material contract, agreement or
      other instrument to which the Master Servicer is a party or by which it
      is bound or to which any of its assets are subject, which violation,
      default or breach would materially and adversely affect the Master
      Servicer's ability to perform its obligations under this Agreement;

      enforcement may be limited by bankruptcy, insolvency, reorganization,
      moratorium and other laws affecting the enforcement of creditors' rights
      in general, and by general equity principles (regardless of whether such
      enforcement is considered in a proceeding in equity or at law);

            (iv) the Master Servicer is not in default with respect to any
      order or decree of any court or any order or regulation of any federal,
      state, municipal or governmental agency to the extent that any such
      default would materially and adversely affect its performance hereunder;

      Servicer's knowledge, threatened against the Master Servicer which would
      prohibit its entering into this Agreement or performing its obligations
      under this Agreement;

<PAGE>

            (x) the Master Servicer has obtained an Errors and Omissions
      Insurance Policy and a Fidelity Bond in accordance with Section 5.02
      each of which is in full force and effect, and each of which provides at
      least such coverage as is required hereunder; and

            (xi) the information about the Master Servicer under the heading
      "The Master Servicer" in the Prospectus Supplement does not include an
      untrue statement of a material fact and does not omit to state a
      material fact, with respect to the statements made, necessary in order
      to make the statements in light of the circumstances under which they
      were made not misleading.

      (b) It is understood and agreed that the representations and warranties
set forth in this Section 5.01 shall survive the execution and delivery of
this Agreement. The Master Servicer shall indemnify the Depositor, the Issuer,
the Indenture Trustee, the Owner Trustee, the Trust Administrator and the
Servicer and hold them harmless against any loss, damages, penalties, fines,
forfeitures, legal fees and related costs, judgments, and other costs and
expenses resulting from any claim, demand, defense or assertion based on or
grounded upon, or resulting from, a breach of the Master Servicer's
representations and warranties contained in this Section 5.01. It is
understood and agreed that the enforcement of the obligation of the Master
Servicer set forth in this Section to indemnify the foregoing parties as
provided in this Section constitutes the sole remedy (other than as set forth
in Section 8.01) of such parties respecting a breach of the foregoing
representations and warranties. Such indemnification shall survive any
termination of the Master Servicer as Master Servicer hereunder, and any
termination of this Agreement.

            Any cause of action against the Master Servicer relating to or
arising out of the breach of any representations and warranties made in this
Section shall accrue upon discovery of such breach by the Depositor, the
Issuer, the Indenture Trustee, the Trust Administrator or the Servicer or
notice thereof by any one of such parties to the other parties.
Notwithstanding anything in this Agreement to the contrary, the Master
Servicer shall not be liable for special, indirect or consequential losses or
damages of any kind whatsoever (including, but not limited to, lost profits).

      Section 5.02. Master Servicer Fidelity Bond and Master Servicer Errors
and Omissions Insurance Policy.

      (a) The Master Servicer, at its expense, shall maintain in effect a
Fidelity Bond and a Errors and Omissions Insurance Policy, affording coverage
with respect to all directors, officers, employees and other Persons acting on
the Master Servicer's behalf, and covering errors and omissions in the
performance of the Master Servicer's obligations hereunder. The Master
Servicer's Errors and Omissions Insurance Policy and the Master Servicer
Fidelity Bond shall be in such form and amount that would be consistent with
coverage customarily maintained by master servicers of mortgage loans similar
to the Mortgage Loans and shall by its terms not be cancelable without
[thirty] days' prior written notice to the Indenture Trustee. The Master
Servicer shall provide the Depositor and the Indenture Trustee, upon request,
with a copy of such policy and fidelity bond. The Master Servicer shall (i)
require the Servicer to maintain an Errors and Omissions Insurance Policy and
a Fidelity Bond in accordance with the provisions of Section 4.02(m) of this
Agreement, (ii) cause the Servicer to provide to the Master Servicer

                                      97
<PAGE>

certificates evidencing that such policy and bond is in effect and to furnish
to the Master Servicer any notice of cancellation, non-renewal or modification
of the policy or bond received by it, as and to the extent provided in Section
4.02(m) of the Agreement, and (iii) furnish copies of such policies and of the
certificates and notices referred to in clause (ii) to the Indenture Trustee
upon request.

      (b) The Master Servicer shall promptly report to the Indenture Trustee
and the Trust Administrator any material changes that may occur in the Master
Servicer's Fidelity Bond or the Master Servicer's Errors and Omissions
Insurance Policy and shall furnish either such party, on request, with
certificates evidencing that such bond and insurance policy are in full force
and effect. The Master Servicer shall promptly report to the Indenture Trustee
and the Trust Administrator all cases of embezzlement or fraud, if such events
involve funds relating to the Mortgage Loans. The total losses, regardless of
whether claims are filed with the applicable insurer or surety, shall be
disclosed in such reports together with the amount of such losses covered by
insurance. If a bond or insurance claim report is filed with any of such
bonding companies or insurers, the Master Servicer shall promptly furnish a
copy of such report to the Indenture Trustee and the Trust Administrator. Any
amounts relating to the Mortgage Loans collected by the Master Servicer under
any such bond or policy shall be promptly remitted by the Master Servicer to
the Trust Administrator for deposit into the Collection Account. Any amounts
relating to the Mortgage Loans collected by the Servicer under any such bond
or policy shall be remitted to the Master Servicer.

      Section 5.03. Master Servicer's Financial Statements and Related
Information. For each year this Agreement is in effect, the Master Servicer
shall deliver to the Trust Administrator, the Indenture Trustee, each Rating
Agency and the Depositor a copy of its annual unaudited financial statements
on or prior to May 31 of each year, beginning May 31, 200_. Such financial
statements shall include a balance sheet, income statement, statement of
retained earnings, statement of additional paid in capital, statement of
changes in financial position and all related notes and schedules and shall be
in comparative form, certified by a nationally recognized firm of Independent
Accountants to the effect that such statements were examined and prepared in
accordance with generally accepted accounting principles applied on a basis
consistent with that of the preceding year.

      Section 5.04. Power to Act; Procedures.

      (a) The Master Servicer shall master service the Mortgage Loans,
provided that the Master Servicer shall not take, or knowingly permit the
Servicer to take, any action that is inconsistent with or prejudices the
interests of the Issuer, the Indenture Trustee or the Noteholders in any
Mortgage Loan or the rights and interests of the Depositor, the Issuer, the
Indenture Trustee and the Noteholders under this Agreement and the Indenture.
The Master Servicer shall represent and protect the interests of the Issuer,
the Indenture Trustee and the Noteholders in the same manner as it protects
its own interests in mortgage loans in its own portfolio in any claim,
proceeding or litigation regarding a Mortgage Loan. Without limiting the
generality of the foregoing, the Master Servicer in its own name, and the
Servicer, to the extent such authority is delegated to such Servicer under
this Agreement, is hereby authorized and empowered by the Indenture Trustee
when the Master Servicer or such Servicer, as the case may be, believes it
appropriate in its best judgment and in accordance with the Servicing
Standard, to

                                      98
<PAGE>

execute and deliver, on behalf of itself and the Noteholders, the Trust
Administrator, the Indenture Trustee 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. The Indenture Trustee shall furnish
the Master Servicer, upon request, with any powers of attorney (on the
standard form used by the Indenture Trustee) empowering the Master Servicer or
the Servicer to execute and deliver instruments of satisfaction or
cancellation, or of partial or full release or discharge, and to foreclose
upon or otherwise liquidate Mortgaged Property, and to appeal, prosecute or
defend in any court action relating to the Mortgage Loans or the Mortgaged
Property, in accordance with this Agreement, and the Indenture Trustee shall
execute and deliver such other documents as the Master Servicer may request,
necessary or appropriate to enable the Master Servicer to master service the
Mortgage Loans and carry out its duties hereunder, and to allow the Servicer
to service the Mortgage Loans in each case in accordance with the Servicing
Standard (and the Indenture Trustee or the Trust Administrator shall have no
liability for misuse of any such powers of attorney by the Master Servicer or
the Servicer). If the Master Servicer or the Indenture Trustee has been
advised that it is likely that the laws of the state in which action is to be
taken prohibit such action if taken in the name of the Indenture Trustee or
that the Indenture Trustee would be adversely affected under the "doing
business" or tax laws of such state if such action is taken in its name, then
upon request of the Indenture Trustee, the Master Servicer shall join with the
Indenture Trustee in the appointment of a co-trustee pursuant to Section 6.10
of the Indenture. In no event shall the Master Servicer, without the Indenture
Trustee's written consent: (i) initiate any action, suit or proceeding solely
under the Indenture Trustee's name without indicating the Master Servicer's
representative capacity or (ii) take any action with the intent to cause, and
which actually does cause, the Indenture Trustee to be registered to do
business in any state. The Master Servicer shall indemnify the Indenture
Trustee for any and all costs, liabilities and expenses incurred by the
Indenture Trustee in connection with the negligent or willful misuse of such
powers of attorney by the Master Servicer. In the performance of its duties
hereunder, the Master Servicer shall be an independent contractor and shall
not, except in those instances where it is taking action in the name of the
Indenture Trustee, be deemed to be the agent of the Indenture Trustee.

      (b) In master servicing and administering the Mortgage Loans, the Master
Servicer shall employ procedures and exercise the same care that it
customarily employs and exercises in master servicing and administering loans
for its own account, giving due consideration to the Servicing Standard where
such practices do not conflict with this Agreement. Consistent with the
foregoing, the Master Servicer may, and may permit the Servicer to, in its
discretion (i) waive any late payment charge and (ii) extend the due dates for
payments due on a Mortgage Note for a period not greater than [120] days;
provided, however, that the maturity of any Mortgage Loan shall not be
extended past the date on which the final payment is due on the latest
maturing Mortgage Loan as of the Cut-off Date. In the event of any extension
described in clause (ii) above, the Master Servicer shall make or cause the
Servicer to make Advances on the related Mortgage Loan in accordance with the
provisions of Section 4.03 on the basis of the amortization schedule of such
Mortgage Loan without modification thereof by reason of such extension.

      Section 5.05. Enforcement of Servicer's and Master Servicer's
Obligations.

                                      99
<PAGE>

      (a) The Master Servicer shall not be required to (i) take any action
with respect to the servicing of any Mortgage Loan that the Servicer is not
required to take under this Agreement and (ii) cause the Servicer to take any
action or refrain from taking any action if this Agreement does not require
the Servicer to take such action or refrain from taking such action.

      (b) The Master Servicer, for the benefit of the Issuer, the Indenture
Trustee and the Noteholders, shall enforce the obligations of the Servicer
hereunder, and shall, in the event that the Servicer fails to perform its
obligations in accordance herewith, terminate the rights and obligations of
the Servicer hereunder and either act as servicer of the related Mortgage
Loans or cause other parties hereto to either assume the obligations of the
Servicer under this Agreement (or agree to execute and deliver a successor
servicing or sub-servicing agreement with a successor servicer). Such
enforcement, including, without limitation, the legal prosecution of claims,
termination of servicing or sub-servicing rights and the pursuit of other
appropriate remedies, shall be in such form and carried out to such an extent
and at such time as the Master Servicer, in its good faith business judgment,
would require were it the owner of the related Mortgage Loans. The Master
Servicer shall pay the costs of such enforcement at its own expense, and shall
be reimbursed therefor initially (i) from a general recovery resulting from
such enforcement only to the extent, if any, that such recovery exceeds all
amounts due in respect of the related Mortgage Loans, (ii) from a specific
recovery of costs, expenses or attorneys' fees against the party against whom
such enforcement is directed, and then, (iii) to the extent that such amounts
are insufficient to reimburse the Master Servicer for the costs of such
enforcement, from the Collection Account.

      Section 5.06. [Reserved]

      Section 5.07. Collection Account.

      (a) On the Closing Date, the Trust Administrator shall open and shall
thereafter maintain a segregated account held in trust in the name of the
Securities Intermediary (the "Collection Account"), entitled "Collection
Account, ____________________________________, as Indenture Trustee, in trust
for Holders of the ______ Mortgage Investment Trust 200_-__, Mortgage Backed
Notes, Series 200_-__." The Collection Account shall relate solely to the
Notes issued by the Issuer, and funds deposited in the Collection Account
shall not be commingled with any other monies.

      (b) The Collection Account shall be an Eligible Account. If an existing
Collection Account ceases to be an Eligible Account, the Trust Administrator
shall establish a new Collection Account that is an Eligible Account within
[10] days and transfer all funds and investment property on deposit in such
existing Collection Account into such new Collection Account.

      (c) The Trust Administrator shall give to the Master Servicer and the
Indenture Trustee prior written notice of the name and address of the
depository institution at which the Collection Account is maintained and the
account number of such Collection Account. The Trust Administrator shall take
such actions as are necessary to cause the depository institution holding the
Collection Account to hold such account in the name of the Indenture Trustee.
On each Payment Date, the entire amount on deposit in the Collection Account
relating to the

                                     100
<PAGE>

Mortgage Loans (subject to permitted withdrawals set forth in Section 5.08),
other than amounts not included in Interest Remittance Amount or Principal
Remittance Amount to be paid to Noteholders for such Payment Date, shall be
applied to make the requested payment of principal and/or interest on each
class of Notes.

      (d) The Master Servicer shall deposit or cause to be deposited in the
Collection Account on the earlier of the applicable Payment Date and [one]
Business Day following receipt thereof, the following amounts received or
payments made by the Master Servicer (other than in respect of principal of
and interest on the Mortgage Loans due on or before the Cut-off Date):

            (i) all remittances from the Custodial Account to the Master
      Servicer pursuant to Section 4.03;

            (ii) all Advances made by the Servicer or the Master Servicer
      pursuant to Section 6.05 hereof and any payment in respect of Prepayment
      Interest Shortfalls paid by the Master Servicer pursuant to Section 5.21
      hereof; and

            (iii) the Purchase Price of any Mortgage Loan repurchased by the
      Depositor or the Seller during the related Prepayment Period or any
      other Person and any Substitution Amount related to any Qualifying
      Substitute Mortgage Loan.

      (e) Funds in the Collection Account may be invested by the Trust
Administrator in Eligible Investments selected by and at the written direction
of the Trust Administrator, which shall mature not later than [one] Business
Day prior to the next Payment Date (or on the Payment Date with respect to any
Eligible Investment of the Trust Administrator or any other fund managed or
advised by it or any Affiliate) and any such Eligible Investment shall not be
sold or disposed of prior to its maturity. All such Eligible Investments shall
be made in the name of the Master Servicer in trust for the benefit of the
Indenture Trustee and the Noteholders. All income and gain realized from any
Eligible Investment shall be for the benefit of the Master Servicer and shall
be subject to its withdrawal or order from time to time, subject to Section
5.08 and shall not be part of the Trust Estate. The amount of any losses
incurred in respect of any such investments shall be deposited in such
Collection Account by the Master Servicer out of its own funds, without any
right of reimbursement therefor, immediately as realized. The foregoing
requirements for deposit in the Collection Account are exclusive, it being
understood and agreed that, without limiting the generality of the foregoing,
payments of interest on funds in the Collection Account and payments in the
nature of late payment charges, assumption fees and other incidental fees and
charges relating to the Mortgage Loans need not be deposited by the Master
Servicer in the Collection Account and may be retained by the Master Servicer
or the Servicer, as applicable, as additional servicing compensation. If the
Master Servicer deposits in the Collection Account any amount not required to
be deposited therein, it may at any time withdraw such amount from such
Collection Account.

      Section 5.08. Application of Funds in the Collection Account. The Trust
Administrator may, from time to time, make, or cause to be made, withdrawals
from the Collection Account for the following purposes:

                                     101
<PAGE>

            (i) to reimburse the Master Servicer or the Servicer, as
      applicable, for any previously unreimbursed Advances or Servicing
      Advances made by any such party, such right to reimbursement pursuant to
      this subclause (i) being limited to amounts received on or in respect of
      a particular Mortgage Loan (including, for this purpose, Liquidation
      Proceeds, Condemnation Proceeds, REO Disposition Proceeds and amounts
      representing Insurance Proceeds with respect to the property subject to
      the related Mortgage) which represent late recoveries (net of the
      applicable Servicing Fee) of payments of principal or interest
      respecting which any such Advance was made, it being understood, in the
      case of any such reimbursement, that the Master Servicer's or Servicer's
      right thereto shall be prior to the rights of the Noteholders;

            (ii) to reimburse the Master Servicer or the Servicer following a
      final liquidation of a Mortgage Loan for any previously unreimbursed
      Advances made by any such party (A) that such party determines in good

      of payments of principal or interest respecting the particular Mortgage
      Loan as to which such Advance was made or from Liquidation Proceeds,
      Condemnation Proceeds, REO Disposition Proceeds or Insurance Proceeds
      with respect to such Mortgage Loan and/or (B) to the extent that such
      unreimbursed Advances exceed the related Liquidation Proceeds or
      Insurance Proceeds, it being understood, in the case of each such
      reimbursement, that the Master Servicer's or Servicer's right thereto
      shall be prior to the rights of the Noteholders;

            (iii) to reimburse the Master Servicer or the Servicer from
      Liquidation Proceeds for Liquidation Expenses and for amounts expended
      by it pursuant to Section 4.02(o) in good faith in connection with the
      restoration of damaged property and, to the extent that Liquidation
      Proceeds after such reimbursement exceed the unpaid principal balance of
      the related Mortgage Loan, together with accrued and unpaid interest
      thereon at the applicable Mortgage Rate less the applicable Servicing
      Fee Rate and Master Servicing Fee Rate for such Mortgage Loan to the Due
      Date next succeeding the date of its receipt of such Liquidation
      Proceeds, to pay to the Master Servicer or the Servicer out of such
      excess the amount of any unpaid assumption fees, late payment charges or
      other Mortgagor charges on the related Mortgage Loan and to retain any
      excess remaining thereafter as additional servicing compensation, it
      being understood, in the case of any such reimbursement or payment, that
      such Master Servicer's or Servicer's right thereto shall be prior to the
      rights of the Noteholders;

            (iv) to pay to the Depositor or the Seller or any other Person, as
      applicable, with respect to each Mortgage Loan or REO Property acquired
      in respect thereof that has been purchased pursuant to this Agreement,
      all amounts received thereon and not paid on the date on which the
      related repurchase was effected, and to pay to the applicable party any
      Advances and Servicing Advances to the extent specified in the
      definition of Purchase Price;

            (v) to the extent not paid by the Servicer, to pay any Insurance
      Premium with respect to a Mortgage Loan;

                                     102
<PAGE>

            (vi) to pay to the Master Servicer income earned on the investment
      of funds on deposit in the Collection Account;

            (vii) on each Payment Date, to make payment to the Noteholders in
      the amounts and in the manner provided for in Section 6.02 for the
      related Payment Date (to the extent collected by the Master Servicer or
      the Servicer);

            (viii) on each Payment Date, to make payment to the Ownership
      Certificate, all Prepayment Premiums received during the immediately
      preceding Prepayment Period;

            (ix) to make payment to itself, the Master Servicer, the Servicer,
      the Indenture Trustee, the Custodian, the Owner Trustee and others

            (x) to withdraw funds deposited in error in the Collection
      Account;

            (xi) to clear and terminate the Collection Account pursuant to
      Article IX; and

            (xii) to reimburse a successor master servicer (solely in its
      capacity as successor master servicer), for any fee or advance
      occasioned by a termination of the Master Servicer, and the assumption
      of such duties by the Indenture Trustee as successor master servicer or
      a successor master servicer appointed by the Indenture Trustee pursuant
      to Section 8.01, in each case to the extent not reimbursed by the
      terminated Master Servicer, it being understood, in the case of any such
      reimbursement or payment, that the right of the Master Servicer or the
      Indenture Trustee thereto shall be prior to the rights of the
      Noteholders.

            In connection with withdrawals pursuant to subclauses (i) and (iv)
above, the Master Servicer's or the Servicer's or such other Person's
entitlement thereto is limited to collections or other recoveries on the
related Mortgage Loan. The Trust Administrator shall therefore keep and
maintain a separate accounting for each Mortgage Loan for the purpose of
justifying any withdrawal from the Collection Account it maintains pursuant to
such subclauses.

      Section 5.09. Reports to Indenture Trustee and Noteholders.

      (a) On each Payment Date, the Trust Administrator shall make available

Agencies and Noteholders via the Trust Administrator's website. The Trust
Administrator's website can be accessed at ______________. Assistance in using
the website can be obtained by calling the Trust Administrator's customer

website are entitled to have a paper copy mailed to them via first class mail
by notifying the Trust Administrator at ____________________,
________________________ (or for overnight deliveries at
_________________________), and indicating such. The Trust Administrator shall
have the right to change the way such statements are distributed in order to
make such distribution more convenient and/or more accessible to the above
parties and the Trust Administrator shall provide timely and adequate
notification to all above parties regarding any such changes.

      The foregoing information and reports shall be prepared and determined
by the Trust Administrator based solely on Mortgage Loan data provided to the
Trust Administrator by the Master Servicer (in a format agreed to by the Trust
Administrator and the Master Servicer) no later than the Payment Date. In
preparing or furnishing the foregoing information, the Trust Administrator and
the Master Servicer shall be entitled to rely conclusively on the accuracy of
the information or data regarding the Mortgage Loans and the related REO
Property that has been provided to the Master Servicer by the Servicer, and
neither the Trust Administrator nor the Master Servicer shall be obligated to
verify, recompute, reconcile or recalculate any such information or data. The
Trust Administrator, the Indenture Trustee, the Custodian and the Master
Servicer shall be entitled to conclusively rely on all of such data and
information provided to the Master Servicer and shall have no liability for
any errors in such data or information.

      (b) Upon the reasonable advance written request of any Noteholder that
is a savings and loan, bank or insurance company, which request, if received
by the Indenture Trustee shall

                                     105
<PAGE>

be forwarded promptly to the Trust Administrator, the Trust Administrator
shall provide, or cause to be provided (or, to the extent that such
information or documentation is not required to be provided by the Servicer,
shall use reasonable efforts to obtain such information and documentation from
the Servicer, and provide), to such Noteholder such reports and access to
information and documentation regarding the Mortgage Loans as such Noteholder
may reasonably deem necessary to comply with applicable regulations of the
Office of Thrift Supervision or its successor or other regulatory authorities
with respect to an investment in the Notes; provided, however, that the Trust
Administrator shall be entitled to be reimbursed by such Noteholder for actual
expenses incurred in providing such reports and access.

      (c) Within [90] days, or such shorter period as may be required by
statute or regulation, after the end of each calendar year, the Trust
Administrator shall have prepared and shall make available to each Person who
at any time during the calendar year was a Noteholder of record, and make
available to Security Owners (identified as such by the Clearing Agency) in
accordance with applicable regulations, a report summarizing the items
provided to the Noteholders pursuant to Section 5.09(a) on an annual basis as
may be required to enable such Holders to prepare their federal income tax
returns; provided, however, that this Section 5.09(c) shall not be applicable
where relevant reports or summaries are required elsewhere in this Agreement.
Such information shall include the amount of original issue discount accrued
on each Class of Notes and information regarding the expenses of the Issuer.
The Trust Administrator shall be deemed to have satisfied such requirement if
it forwards such information in any other format permitted by the Code. The
Master Servicer shall provide the Trust Administrator with such information as
is necessary for the Trust Administrator to prepare such reports.

      (d) The Trust Administrator shall furnish any other information that is
required by the Code and regulations thereunder to be made available to
Noteholders. The Master Servicer shall provide the Trust Administrator with
such information as is necessary for the Trust Administrator to prepare such
reports (and the Trust Administrator may rely solely upon such information).

      Section 5.10. Termination of Servicer; Successor Servicers.

      (a) The Master Servicer shall be entitled to terminate the rights and
obligations of the Servicer upon the occurrence of a Servicer Event of Default
as set forth in Section 4.07; provided, however, that in the event of
termination of the Servicer, the Master Servicer shall provide for the
servicing of the Mortgage Loans by a successor servicer as provided in Section
4.08.

      The parties acknowledge that notwithstanding the preceding sentence,
there may be a transition period, not to exceed [90] days, in order to effect
the transfer of servicing to a successor servicer. The Master Servicer shall
be entitled to be reimbursed by the Servicer (or by the Trust Estate, if the
Servicer is unable to fulfill its obligations hereunder) for all costs
associated with the transfer of servicing, including without limitation, any
costs or expenses associated with the complete transfer of all servicing data
and the completion, correction or manipulation of such servicing data, as may
be required by the Master Servicer to correct any

                                     106
<PAGE>

errors or insufficiencies in the servicing data or otherwise to enable the
Master Servicer to service the Mortgage Loans properly and effectively.

      (b) If the Master Servicer acts as a successor Servicer, it shall not
assume liability for the representations and warranties of the Servicer that
it replaces. The Master Servicer shall use reasonable efforts to have the
successor Servicer assume liability for the representations and warranties
made by the terminated Servicer and in the event of any such assumption by the
successor servicer, the Master Servicer may, in the exercise of its business
judgment, release the terminated Servicer from liability for such
representations and warranties.

      (c) If the Master Servicer acts as a successor Servicer, it will have no
obligation to make an Advance if it determines in its reasonable judgment that
such Advance would constitute a Nonrecoverable Advance.

      Section 5.11. Master Servicer Liable for Enforcement. The Master
Servicer shall use commercially reasonable efforts to ensure that the Mortgage
Loans are serviced in accordance with the provisions of this Agreement and
shall use commercially reasonable efforts to enforce the provisions of Article
IV for the benefit of the Noteholders. The Master Servicer shall be entitled
to enter into any agreement with any Servicer for indemnification of the
Master Servicer and nothing contained in this Agreement shall be deemed to
limit or modify such indemnification. Except as expressly set forth herein,
the Master Servicer shall have no liability for the acts or omissions of the
Servicer in the performance by such Servicer of its obligations under Article
IV.

      Section 5.12. Assumption of Master Servicing by Indenture Trustee.

      (a) In the event the Master Servicer shall for any reason no longer be
the Master Servicer (including by reason of any Master Servicer Event of
Default under Section 8.01 of this Agreement), the Indenture Trustee shall
thereupon assume all of the rights and obligations of such Master Servicer
hereunder. The Indenture Trustee, its designee or any successor master
servicer appointed by the Indenture Trustee shall be deemed to have assumed
all of the Master Servicer's interest herein, except that the Master Servicer
shall not thereby be relieved of any liability or obligations of the Master
Servicer accruing prior to its replacement as Master Servicer, and shall be
liable to the Indenture Trustee, and hereby agrees to indemnify and hold
harmless the Indenture Trustee from and against all costs, damages, expenses
and liabilities (including reasonable attorneys' fees) incurred by the
Indenture Trustee as a result of such liability or obligations of the Master
Servicer and in connection with the Indenture Trustee's assumption (but not
its performance, except to the extent that costs or liability of the Indenture
Trustee are created or increased as a result of negligent or wrongful acts or
omissions of the Master Servicer prior to its replacement as Master Servicer)
of the Master Servicer's obligations, duties or responsibilities thereunder.

      (b) The Master Servicer that has been terminated shall, upon request of
the Indenture Trustee but at the expense of such Master Servicer, deliver to
the assuming party all documents and records relating to the Mortgage Loans
and an accounting of amounts collected and held by it and otherwise use its
best efforts to effect the orderly and efficient transfer of master servicing
to the assuming party.

      Section 5.13. [Reserved]

      Section 5.14. Release of Mortgage Files.

      (a) Upon (i) becoming aware of the payment in full of any Mortgage Loan
or (ii) the receipt by the Master Servicer of a notification that payment in
full has been or will be escrowed in a manner customary for such purposes, the
Master Servicer will, or will cause the Servicer to, promptly notify the
Indenture Trustee (or the Custodian) by a certification (which certification
shall include a statement to the effect that all amounts received in
connection with such payment that are required to be deposited in the
Collection Account maintained by the Trust Administrator pursuant to Section
5.07 have been or will be so deposited) of a Servicing Officer and shall
request (on the form attached to the Custodial Agreement) the Indenture
Trustee or the Custodian, to deliver to the Servicer the related Mortgage
File. Upon receipt of such certification and request, the Indenture Trustee or
the Custodian (with the consent, and at the direction of the Indenture
Trustee), shall promptly release the related Mortgage File to the Servicer and
the Indenture Trustee shall have no further responsibility with regard to such
Mortgage File. Upon any such payment in full, the Master Servicer is
authorized, and the Servicer is authorized, to give, as agent for the
Indenture Trustee, as the mortgagee under the Mortgage that secured the
Mortgage Loan, an instrument of satisfaction (or assignment of mortgage
without recourse) regarding the Mortgaged Property subject to the Mortgage,
which instrument of satisfaction or assignment, as the case may be, shall be
delivered to the Person or Persons entitled thereto against receipt therefor
of such payment, it being understood and agreed that no expenses incurred in
connection with such instrument of satisfaction or assignment, as the case may
be, shall be chargeable to the Collection Account.

      (b) From time to time and as appropriate for the servicing or
foreclosure of any Mortgage Loan, the Indenture Trustee shall execute such
documents as shall be prepared and furnished to the Indenture Trustee by the
Master Servicer, or by the Servicer, as applicable, (in a form reasonably
acceptable to the Indenture Trustee) and as are necessary for the prosecution
of any such proceedings. The Indenture Trustee or the Custodian, shall, upon
request of the Master Servicer or of the Servicer, as applicable, and delivery
to the Indenture Trustee or the Custodian, of a trust receipt signed by a
Servicing Officer substantially in the form attached to the Custodial
Agreement, release the related Mortgage File held in its possession or control
to the Master Servicer (or the Servicer, as applicable). Such trust receipt
shall obligate the Master Servicer or the Servicer, as applicable, to return
the Mortgage File to the Indenture Trustee or the Custodian, as applicable,
when the need therefor by the Master Servicer or the Servicer, as applicable,
no longer exists unless the Mortgage Loan shall be liquidated, in which case,
upon receipt of a certificate of a Servicing Officer similar to that
hereinabove specified, the trust receipt shall be released by the Indenture
Trustee or the Custodian, as applicable, to the Master Servicer or the
Servicer as applicable.

      Section 5.15. Documents, Records and Funds in Possession of Master
Servicer To Be Held for Indenture Trustee.

      (a) The Master Servicer shall transmit, or cause the Servicer to
transmit, to the Indenture Trustee such documents and instruments coming into
the possession of the Master Servicer or the Servicer from time to time as are
required by the terms hereof to be delivered to

                                     108
<PAGE>

the Indenture Trustee or the Custodian. Any funds received by the Master
Servicer or by the Servicer in respect of any Mortgage Loan or which otherwise
are collected by the Master Servicer or the Servicer as Liquidation Proceeds
or Insurance Proceeds in respect of any Mortgage Loan shall be held for the
benefit of the Indenture Trustee and the Noteholders subject to the Master
Servicer's right to retain or withdraw amounts provided in this Agreement and
to the right of the Servicer to retain its Servicing Fee and other amounts as
provided herein. The Master Servicer shall, and shall cause the Servicer to,
provide access to information and documentation regarding the Mortgage Loans
to the Indenture Trustee, their respective agents and accountants at any time
upon reasonable request and during normal business hours, and to Noteholders
that are savings and loan associations, banks or insurance companies, the
Office of Thrift Supervision, the FDIC and the supervisory agents and
examiners of such Office and Corporation or examiners of any other federal or
state banking or insurance regulatory authority if so required by applicable
regulations of the Office of Thrift Supervision or other regulatory authority,
such access to be afforded without charge but only upon reasonable request in
writing and during normal business hours at the offices of the Master Servicer
designated by it. In fulfilling such a request the Master Servicer shall not
be responsible for determining the sufficiency of such information.

      (b) All Mortgage Files and funds collected or held by, or under the
control of, the Master Servicer or the Servicer, in respect of any Mortgage
Loans, whether from the collection of principal and interest payments or from
Liquidation Proceeds or Insurance Proceeds, shall be held by the Master
Servicer or by the Servicer for and on behalf of the Indenture Trustee as the
Indenture Trustee's agent and bailee for purposes of perfecting the Indenture
Trustee's security interest therein as provided by relevant Uniform Commercial
Code or laws; provided, however, that the Master Servicer and the Servicer
shall be entitled to setoff against, and deduct from, any such funds any
amounts that are properly due and payable to the Master Servicer or the
Servicer under this Agreement and shall be authorized to remit such funds to
the Trust Administrator in accordance with this Agreement.

      (c) The Master Servicer hereby acknowledges that concurrently with the
execution of this Agreement, the Indenture Trustee shall own or, to the extent
that a court of competent jurisdiction shall deem the conveyance of the
Mortgage Loans from the Seller to the Depositor not to constitute a sale, the
Indenture Trustee shall have a security interest in the Mortgage Loans and in
all Mortgage Files representing such Mortgage Loans and in all funds and
investment property now or hereafter held by, or under the control of, the
Servicer or the Master Servicer that are collected by the Servicer or the
Master Servicer in connection with the Mortgage Loans, whether as scheduled
installments of principal and interest or as full or partial prepayments of
principal or interest or as Liquidation Proceeds or Insurance Proceeds or
otherwise, and in all proceeds of the foregoing and proceeds of proceeds (but
excluding any fee or other amounts to which the Servicer or the Master
Servicer is entitled to hereunder); and the Master Servicer agrees that so
long as the Mortgage Loans are assigned to and held by the Indenture Trustee
or the Custodian, all documents or instruments constituting part of the
Mortgage Files, and such funds relating to the Mortgage Loans which come into
the possession or custody of, or which are subject to the control of, the
Master Servicer or the Servicer shall be held by the Master Servicer or the
Servicer for and on behalf of the Indenture Trustee as the Indenture Trustee's
agent and bailee for purposes of perfecting the Indenture Trustee's security
interest therein as provided by the applicable Uniform Commercial Code or
other applicable laws.

                                     109
<PAGE>

      (d) The Master Servicer agrees that it shall not, and shall not
authorize the Servicer to, create, incur or subject any Mortgage Loans, or any
funds that are deposited in any Custodial Account, Escrow Account or the
Collection Account, or any funds that otherwise are or may become due or
payable to or for the benefit of the Indenture Trustee, to any claim, lien,
security interest, judgment, levy, writ of attachment or other encumbrance,
nor assert by legal action or otherwise any claim or right of setoff against
any Mortgage Loan or any funds collected on, or in connection with, a Mortgage
Loan.

      Section 5.16. Opinion. On or before the Closing Date, the Master
Servicer shall cause to be delivered to the Depositor, the Seller, the
Indenture Trustee, the Issuer, the Trust Administrator and the Servicer one or
more Opinions of Counsel, dated the Closing Date, in form and substance
reasonably satisfactory to the Depositor, as to the due authorization,
execution and delivery of this Agreement by the Master Servicer and the
enforceability thereof.

behalf of the Indenture Trustee) shall retain possession and custody of the
originals of the primary mortgage insurance policies or certificate of
insurance if applicable and any certificates of renewal as to the foregoing as
may be issued from time to time as contemplated by this Agreement. Until all
amounts payable in respect of the Notes have been paid in full and the Master
Servicer otherwise has fulfilled its obligations under this Agreement, the
Indenture Trustee (or the Custodian) shall also retain possession and custody
of each Mortgage File in accordance with and subject to the terms and
conditions of this Agreement. The Master Servicer shall promptly deliver or
cause the Servicer to deliver to the Indenture Trustee (or the Custodian),

equal to the lesser of (i) its master servicing compensation with respect to
such Payment Date and (ii) the amount of any Compensating Interest Payment
required to be paid by the Servicer with respect to such Payment Date pursuant
to this Agreement, but which is not paid by the Servicer on its behalf. The

      Section 5.25. [Reserved]

      Section 5.26. Merger or Consolidation. Any Person into which the Master
Servicer may be merged or consolidated, or any Person resulting from any
merger, conversion, other change in form or consolidation to which the Master
Servicer shall be a party, or any Person succeeding to the business of the
Master Servicer, shall be the successor to the Master Servicer 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;
provided, however, that the successor or resulting Person to the Master
Servicer shall be a Person that shall be qualified and approved (or that have
an Affiliate that is qualified and approved) to service mortgage loans for
Fannie Mae or FHLMC and shall have a net worth of not less than $[15,000,000].

            As a condition to the effectiveness of any merger or
consolidation, at least 15 calendar days prior to the effective date of any
merger or consolidation of the Master Servicer, the Master Servicer shall
provide (x) written notice to the Depositor of any successor pursuant to this
Section and (y) in writing and in form and substance reasonably satisfactory
to the Depositor, all information reasonably requested by the Depositor in
order to comply with its reporting obligation under Item 6.02 of Form 8-K with
respect to the resignation of the Master Servicer.

      Section 5.27. Resignation of Master Servicer. Except as otherwise
provided in Sections 5.26 and this Section 5.27 hereof, the Master Servicer
shall not resign from the obligations and duties hereby imposed on it unless
it determines that the Master Servicer's duties hereunder are no longer
permissible under applicable law or are in material conflict by reason of
applicable law with any other activities carried on by it and cannot be cured.
Any such determination permitting the resignation of the Master Servicer shall
be evidenced by an Opinion of Counsel that shall be Independent to such effect
delivered to the Indenture Trustee. No such resignation shall become effective

servicer shall have been appointed by the Indenture Trustee and until such
successor shall have assumed, the Master Servicer's responsibilities and
obligations under this Agreement and (b) the Depositor shall have received the

effective date of such resignation, the Master Servicer shall provide (x)
written notice to the Depositor of any successor pursuant to this Section and
(y) in writing and in form and substance reasonably satisfactory to the
Depositor, all information reasonably requested by the Depositor in order to

<PAGE>

benefits or privileges hereunder to any other Person, or delegate to or
subcontract with, or authorize or appoint any other Person to perform any of
the duties, covenants or obligations to be performed by the Master Servicer
hereunder, unless the Indenture Trustee and the Depositor shall have consented
to such action; provided, however, that the Master Servicer shall have the
right without the prior written consent of the Indenture Trustee or the
Depositor to delegate or assign to or subcontract with or authorize or appoint
an Affiliate of the Master Servicer to perform and carry out any duties,
covenants or obligations to be performed and carried out by the Master
Servicer hereunder. In no case, however, shall any such delegation,
subcontracting or assignment to an Affiliate of the Master Servicer relieve
the Master Servicer of any liability hereunder. Notice of such permitted
assignment shall be given promptly by the Master Servicer to the Depositor and
the Indenture Trustee. If, pursuant to any provision hereof, the duties of the
Master Servicer are transferred to a successor master servicer, the entire
amount of compensation payable to the Master Servicer pursuant hereto,
including amounts payable to or permitted to be retained or withdrawn by the
Master Servicer pursuant to Section 5.21 hereof, shall thereafter be payable
to such successor master servicer.

      Section 5.29. Limitation on Liability of the Master Servicer and Others.

      (a) The Master Servicer undertakes to perform such duties and only such
duties as are specifically set forth in this Agreement.

      (b) No provision of this Agreement shall be construed to relieve the
Master Servicer from liability for its own negligent action, its own negligent
failure to act or its own willful misconduct; provided, however, that the
duties and obligations of the Master Servicer shall be determined solely by
the express provisions of this Agreement, the Master Servicer shall not be
liable 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 Master Servicer and, in absence
of bad faith on the part of the Master Servicer, the Master Servicer 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 Master Servicer and conforming to the requirements of this Agreement.

      (c) Neither the Master Servicer nor any of the directors, officers,
employees or agents of the Master Servicer shall be under any liability to the
Indenture Trustee or the Noteholders 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 Master Servicer or any such person against any liability that would
otherwise be imposed by reason of willful misfeasance, bad faith or negligence
in its performance of its duties or by reason of reckless disregard for its
obligations and duties under this Agreement. The Master Servicer and any
director, officer, employee or agent of the Master Servicer shall be entitled
to indemnification by the Trust Estate and will be held harmless against any
loss, liability or expense incurred in connection with any legal action
relating to this Agreement, the Notes or any other Operative Agreement other
than any loss, liability or expense incurred by reason of willful misfeasance,
bad faith or negligence in the performance of his or its duties hereunder or
by reason of reckless disregard of his or its obligations and duties
hereunder. The Master Servicer and any director, officer, employee or agent of
the Master Servicer may rely in good faith on any document of any kind prima
facie properly executed and submitted by any Person respecting any

                                     113
<PAGE>

matters arising hereunder. The Master Servicer shall be under no obligation to
appear in, prosecute or defend any legal action that is not incidental to its
duties to master service the Mortgage Loans in accordance with this Agreement
and that in its opinion may involve it in any expenses or liability; provided,
however, that the Master Servicer may in its sole discretion undertake any
such action that it may deem necessary or desirable with respect to this
Agreement and the rights and duties of the parties hereto and the interests of
the Noteholders 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 Issuer and the Master Servicer shall be entitled to be
reimbursed therefor out of the Collection Account it maintains as provided by
Section 4.08.

      Section 5.30. Indemnification; Third Party Claims. The Master Servicer
agrees to indemnify the Depositor, the Issuer, the Indenture Trustee, the
Owner Trustee and the Servicer and hold them harmless against any and all
claims, losses, penalties, fines, forfeitures, legal fees and related costs,
judgments, and any other costs, liability, fees and expenses that the
Depositor, the Issuer, the Indenture Trustee, the Owner Trustee or the
Servicer may sustain as a result of the failure of the Master Servicer to
perform its duties and master service the Mortgage Loans in compliance with
the terms of this Agreement. The Depositor, the Issuer, the Indenture Trustee,
the Owner Trustee and the Servicer shall immediately notify the Master
Servicer if a claim is made by a third party with respect to this Agreement,
the Mortgage Loans entitling the Depositor, the Issuer, the Indenture Trustee,
the Owner Trustee or the Servicer to indemnification under this Section 5.30,
whereupon the Master Servicer shall assume 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 them in respect of such claim. The failure to provide such immediate
notice shall not affect the Master Servicer's obligation pursuant to this
Section 5.30 to indemnify the Depositor, the Issuer, the Indenture Trustee,
the Owner Trustee and the Servicer, except to the extent that the Master
Servicer is materially prejudiced by such failure to notify.

      Section 5.31. Alternative Index. In the event that the Servicer notifies
the Master Servicer in writing that the Index for any Mortgage Loan, as
specified in the related Mortgage Note, becomes unavailable for any reason,
the Master Servicer shall select an alternative index in accordance with the
terms of such Mortgage Note or, if such Mortgage Note does not make provision
for the selection of an alternative index in such event, the Master Servicer

      such other institution has Control;

      (c) The Securities Intermediary hereby confirms that (A) the Trust

notifies the Securities Intermediary in writing that the Issuer has been
terminated or the Indenture discharged in accordance herewith and with the
Trust Agreement or the Indenture, as applicable, and the security interest

time. The obligations of the Securities Intermediary hereunder shall continue
in effect until the security interest of the Indenture Trustee in the Trust
Account, and in such Security Entitlements, has been terminated pursuant to
the terms of this Agreement and the Indenture Trustee or the Issuer, as
applicable, has notified the Securities Intermediary of such termination in
writing; and

      (i) Notwithstanding anything else contained herein, the Depositor and

delivered or credited to it in connection with such account and all
investments thereof will be promptly credited to the applicable account.

revocable by the Indenture Trustee or by the Owner Trustee with the consent of

taken such further actions, to execute, deliver and file or cause to be

(including, without limitation, any financing statements under the Relevant
UCC or this Agreement) as may be necessary to perfect the interests created by
this Section in favor of the Issuer and the Indenture Trustee and otherwise

      the law of any jurisdiction other than the State under which each is
      organized as of the Closing Date (whether changing its jurisdiction of
      organization or organizing under an additional jurisdiction) without
      giving [30] days prior written notice of such action to its immediate
      and mediate transferee, including the Indenture Trustee. Before
      effecting such change, each of the Depositor or the Issuer proposing to
      change its jurisdiction of organization shall prepare and file in the
      appropriate filing office any financing statements or other statements
      necessary to continue the perfection of the interests of its immediate
      and mediate transferees, including the Indenture Trustee, in the Trust
      Account Property. In connection with the transactions contemplated by
      the Operative Agreements relating to the Trust Account Property, each of
      the Depositor and the Issuer authorizes its immediate or mediate
      transferee to file in any filing office any initial financing
      statements, any

      other statements or filings described in this Section 6.04.

      None of the Securities Intermediary or any director, officer, employee
or agent of the Securities Intermediary shall be under any liability to the
Indenture Trustee or the Noteholders for any action taken, or not taken, in
good faith pursuant to this Agreement, or for errors in judgment; provided,
however, that this provision shall not protect the Securities Intermediary
against any liability to the Indenture Trustee or the Noteholders which would
otherwise be imposed by reason of the Securities Intermediary's willful
misconduct, bad faith or negligence in the performance of its obligations or
duties hereunder. The Securities Intermediary and any director, officer,
employee or agent of the Securities Intermediary may rely in good faith on any
document of any kind which, prima facie, is properly executed and submitted by
any Person respecting any matters arising hereunder. The Securities
Intermediary shall be under no duty to inquire into or investigate the
validity, accuracy or content of such document. The Issuer shall indemnify the
Securities Intermediary for and hold it harmless against any loss, liability
or expense arising out of or in connection with this Agreement and carrying
out its duties hereunder, including the costs and expenses of defending itself
against any claim of liability, except in those cases where the Securities
Intermediary has been guilty of bad faith, negligence or willful misconduct.
The foregoing indemnification shall survive any termination of this Agreement

      (a) Subject to Section 4.03(c), Advances shall be made in respect of

such amount to the extent provided in Section 4.03(c) hereof. If any Servicer
fails to remit Advances required to be made under Section 4.03(c) hereof, the
Master Servicer shall itself make, or shall cause the successor Servicer to
make, such Advance on the Servicer Remittance Date immediately following such

advanced by the applicable Servicer) for deposit in the Collection Account
immediately available funds in an amount equal to such Advance. The Master
Servicer and the Servicer shall be entitled to be reimbursed from the
Collection Account, and the Servicer shall be entitled to be reimbursed from
its respective Custodial Account, for all Advances made by it as provided in

make such Advance.

      (b) In the event that the Master Servicer or Servicer fails for any
reason to make an Advance required to be made pursuant to this Section 6.05,

related Payment Date, deposit in the Collection Account an amount equal to the
excess of (a) Advances required to be made by the Master Servicer or the
Servicer that would have been deposited in such Collection Account over (b)
the amount of any Advance made by the Master Servicer or the Servicer with
respect to such Payment Date; provided, however, that the Indenture Trustee as
successor Master Servicer shall be required to

                                     134
<PAGE>

make such Advance only if it is not prohibited by law from doing so and it has
determined that such Advance would be recoverable from amounts to be received
with respect to such Mortgage Loan, including late payments, Liquidation
Proceeds, Insurance Proceeds, or otherwise. The Indenture Trustee shall be
entitled to be reimbursed from the Collection Account for Advances made by it
pursuant to this Section 6.05 as if it were the Master Servicer and shall be
entitled to receive all compensation and fees of the Master Servicer in
accordance with Section 8.01(b).

      (c) At the time of the execution hereof, and for the purposes hereof,
the Trust Administrator shall establish a special purpose trust account in the
name of the Trust Administrator for the benefit of Holders of the [Class
AF-5B] Notes (the "[Class AF-5B] Policy Payments Account") over which the
Trust Administrator shall have exclusive control and sole right of withdrawal.
The [Class AF-5B] Policy Payments Account shall be an Eligible Account. The
Trust Administrator shall deposit any amount paid under the [Class AF-5B]
Policy into the [Class AF-5B] Policy Payments Account and distribute such
amount only for the purposes of making the payments to Holders of the [Class
AF-5B] Notes, in respect of the related Deficiency Amount for which the
related claim was made under the [Class AF-5B] Policy. Such amounts shall be
allocated by the Trust Administrator to Holders of [Class AF-5B] Notes
affected by such shortfalls in the same manner as principal and interest
payments are to be allocated with respect to such Certificates pursuant to
Section 6.02. It shall not be necessary for such payments to be made by checks
or wire transfers separated from the checks or wire transfers used to make
regular payments hereunder with funds withdrawn from the Collection Account.
However, any payments made on the [Class AF-5B] Notes from funds in the [Class
AF-5B] Policy Payments Account shall be noted as provided in subsection (e)
below. Funds held in the [Class AF-5B] Policy Payments Account shall not be
invested by the Trust Administrator.

      (d) Any funds received from the [Class AF-5B] Insurer for deposit into
the [Class AF-5B] Policy Payments Account pursuant to the [Class AF-5B] Policy
in respect of a Payment Date or otherwise as a result of any claim under the
[Class AF-5B] Policy shall be applied by the Trust Administrator directly to
the payment in full (i) of the related Deficiency Amount on such Payment Date
or (ii) of other amounts payable under the [Class AF-5B] Policy. Funds
received by the Trust Administrator as a result of any claim under the [Class
AF-5B] Policy shall be used solely for payment to the Holders of the [Class
AF-5B] Notes and may not be applied for any other purpose, including, without
limitation, satisfaction of any costs, expenses or liabilities of the Trust
Administrator, the Master Servicer or the Trust Fund. Any funds remaining in
the [Class AF-5B] Policy Payments Account on the [first] Business Day after
each Payment Date shall be remitted promptly to the [Class AF-5B] Insurer in
accordance with the instructions set forth in Section 6.02.

      (e) The Trust Administrator shall keep complete and accurate records in
respect of (i) all funds remitted to it by the [Class AF-5B] Insurer and
deposited into the [Class AF-5B] Policy Payments Account and (ii) the
allocation of such funds to (A) payments of interest on and principal in
respect of any [Class AF-5B] Notes and (B) the amount of funds available to
make distributions on the [Class AF-5B] Notes pursuant to Sections 6.02. The
[Class AF-5B] Insurer shall have the right to inspect such records at
reasonable times during normal business hours upon [three] Business Days'
prior notice to the Trust Administrator.

      (f) The Trust Administrator acknowledges, and each Holder of a [Class
AF-5B] Note by its acceptance of the [Class AF-5B] Note agrees, that, without
the need for any further action on the part of the [Class AF-5B] Insurer or
the Trust Administrator, to the extent the [Class AF-5B] Insurer makes
payments, directly or indirectly, on account of principal of or interest on
any [Class AF-5B] Notes, the [Class AF-5B] Insurer will be fully subrogated to
the rights of the Holders of such [Class AF-5B] Notes to receive such
principal and interest from the Trust Fund. The Holders of the [Class AF-5B]
Notes, by acceptance of the [Class AF-5B] Notes, assign their rights as
Holders of the [Class AF-5B] Notes to the extent of the [Class AF-5B]
Insurer's interest

                                     137
<PAGE>

with respect to amounts paid under the [Class AF-5B] Policy. Anything herein
to the contrary notwithstanding, solely for purposes of determining the [Class
AF-5B] Insurer's rights, as applicable, as subrogee for payments distributable
pursuant to Section 6.02, any payment with respect to distributions to the
[Class AF-5B] Notes which is made with funds received pursuant to the terms of
the [Class AF-5B] Policy shall not be considered payment of the [Class AF-5B]
Notes from the Trust Fund and shall not result in the distribution or the
provision for the distribution in reduction of the Note Principal Amount of
the [Class AF-5B] Notes within the meaning of Article VI.

insolvency, receivership, rehabilitation or similar law (an "Insolvency
Proceeding") and (B) the making of any claim in connection with any Insolvency
Proceeding seeking the avoidance as a preferential transfer (a "Preference
Claim") of any distribution made with respect to the [Class AF-5B] Notes as to
which it has actual knowledge. Each Holder of a [Class AF-5B] Note, by its
purchase of [Class AF-5B] Notes, and the Trust Administrator hereby agrees
that the [Class AF-5B] Insurer (so long as no [Class AF-5B] Insurer Default
exists) 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 any 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 [Class AF-5B] Insurer shall be
subrogated to the rights of the Trust Administrator and each Holder of a
[Class AF-5B] Note in the conduct of any 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.

      (i) The Master Servicer shall designate a [Class AF-5B] Insurer Contact
Person who shall be available to the [Class AF-5B] Insurer to provide
reasonable access to information regarding the Mortgage Loans. The initial

Marketing.

      (j) The Trust Administrator shall surrender the [Class AF-5B] Policy to
the [Class AF-5B] Insurer for cancellation upon the reduction of the Note

      (k) For so long as there is no continuing default by the [Class AF-5B]
Insurer under its obligations under the [Class AF-5B] Policy (a "[Class AF-5B]
Insurer Default"), each Holder of a [Class AF-5B] Note agrees that the [Class
AF-5B] Insurer shall be treated by the Depositor, the Master Servicer and the
Trust Administrator as if the [Class AF-5B] Insurer were the Holder of all of
the [Class AF-5B] Notes, for the purpose (and solely for the purpose) of the
giving of any consent, the making of any direction or the exercise of any
voting or other control rights otherwise given to the Holders of the [Class
AF-5B] Notes hereunder.

7.09 deliver to the successor Trust Administrator all property and documents
of or relating to the Collateral then in the custody of the Trust
Administrator, or if this Agreement has been terminated, to the Depositor. In
the event of the resignation or removal of the Trust Administrator pursuant to
Section 7.09, the Trust Administrator shall cooperate with the Issuer and take
all reasonable steps requested to assist the Issuer in making an orderly
transfer of the duties of the Trust Administrator.

      Principal Amount of each Class of Notes affected thereby; or

            (ii) Any failure on the part of the Master Servicer duly to

                                     145
<PAGE>

      days after the date on which written notice of such failure, requiring
      the same to be remedied, shall have been given to the Master Servicer by
      the Indenture Trustee or the Trust Administrator or to the Master
      Servicer and the Indenture Trustee by the Majority Noteholders; or

            (iii) A decree or order of a court or agency or supervisory
      authority having jurisdiction for the appointment of a conservator or
      receiver or liquidator in any insolvency, readjustment of debt,
      marshalling of assets and liabilities or similar proceedings, or for the
      winding up or liquidation of its affairs, shall have been entered
      against the Master Servicer, and such decree or order shall have
      remained in force undischarged or unstayed for a period of [60] days or
      any Rating Agency reduces or withdraws or threatens to reduce or
      withdraw the rating of the Notes because of the financial condition or
      loan servicing capability of such Master Servicer; or

            (iv) The Master Servicer shall consent to the appointment of a
      conservator or receiver or liquidator in any insolvency, readjustment of
      debt, marshalling of assets and liabilities, voluntary liquidation or
      similar proceedings of or relating to the Master Servicer or of or
      relating to all or substantially all of its property; or

            (v) The Master Servicer shall admit in writing its inability to
      pay its debts generally as they become due, file a petition to take
      advantage of any applicable insolvency or reorganization statute, make
      an assignment for the benefit of its creditors or voluntarily suspend
      payment of its obligations; or

            (vi) The Master Servicer shall be dissolved, or shall dispose of
      all or substantially all of its assets, or consolidate with or merge
      into another entity or shall permit another entity to consolidate or
      merge into it, such that the resulting entity does not meet the criteria
      for a successor servicer as specified in Section 5.26 hereof; or

            (vii) If a representation or warranty set forth in Section 5.01
      hereof shall prove to be incorrect as of the time made in any respect
      that materially and adversely affects the interests of the Noteholders,
      and the circumstance or condition in respect of which such
      representation or warranty was incorrect shall not have been eliminated
      or cured within [30] days after the date on which written notice of such
      incorrect representation or warranty shall have been given to the Master
      Servicer by the Indenture Trustee or the Trust Administrator, or to the
      Master Servicer and the Indenture Trustee by the Majority Noteholders;
      or

            (viii) A sale or pledge of any of the rights of the Master
      Servicer hereunder or an assignment of this Agreement by the Master
      Servicer or a delegation of the rights or duties of the Master Servicer
      hereunder shall have occurred in any manner not otherwise permitted
      hereunder and without the prior written consent of the Indenture Trustee
      and the Majority Noteholders; or

            (ix) The Master Servicer has notice or actual knowledge that the
      Servicer at any time is not either an FHA Approved Mortgagee, and the
      Master Servicer has not terminated the rights and obligations of such
      Servicer under this Agreement and replaced

                                     146
<PAGE>

      the Servicer with an FHA Approved Mortgagee within [60] days of the date
      the Master Servicer receives such notice or acquires such actual
      knowledge; or

            (x) Any failure of the Master Servicer to remit to the Trust
      Administrator any Advance required to be made to the Trust Administrator
      for the benefit of Noteholders under the terms of this Agreement, which
      failure continues unremedied as of the close of business on the Business
      Day prior to a Payment Date.

      If a Master Servicer Event of Default described in clauses (i) through
(ix) of this Section 8.01 shall occur, then, in each and every case, subject
to applicable law, so long as any such Master Servicer Event of Default shall
not have been remedied within any period of time prescribed by this Section
8.01, the Indenture Trustee, upon obtaining actual knowledge thereof, by
notice in writing to the Master Servicer may, and shall, if so directed by the
Majority Noteholders, terminate all of the rights and obligations of the
Master Servicer hereunder and in and to the Mortgage Loans and the proceeds
thereof; provided that in the event of a Master Servicer Event of Default
related to the obligations set forth in Section 5.24(a), Section 4.08(a) (with
respect to notice to the Depositor) or Article XI, the Master Servicer may
only be terminated at the direction of the Depositor. If a Master Servicer
Event of Default described in clause (x) of this Section 8.01 shall occur,
then, in each and every case, subject to applicable law, so long as such
Master Servicer Event of Default shall not have been remedied within the time
period prescribed by clause (x) of this Section 8.01, the Indenture Trustee,
by notice in writing to the Master Servicer, shall promptly terminate all of
the rights and obligations of the Master Servicer hereunder and in and to the
Mortgage Loans and the proceeds thereof. On or after the receipt by the Master
Servicer of such written notice, all authority and power of the Master
Servicer, and only in its capacity as Master Servicer under this Agreement,
whether with respect to the Mortgage Loans or otherwise, shall pass to and be
vested in the Indenture Trustee pursuant to and under the terms of this
Agreement; and the Indenture Trustee is hereby authorized and empowered to
execute and deliver, on behalf of the defaulting Master 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. The defaulting Master Servicer agrees to cooperate
with the Indenture Trustee in effecting the termination of the defaulting
Master Servicer's responsibilities and rights hereunder as Master Servicer
including, without limitation, notifying the Servicer of the assignment of the
master servicing function and providing the Indenture Trustee or its designee
all documents and records in electronic or other form reasonably requested by
it to enable the Indenture Trustee or its designee to assume the defaulting
Master Servicer's functions hereunder and the transfer to the Indenture
Trustee for administration by it of all amounts which shall at the time be or
should have been deposited by the defaulting Master Servicer in the Collection
Account maintained by such defaulting Master Servicer and any other account or
fund maintained with respect to the Notes or thereafter received with respect
to the Mortgage Loans. The Master Servicer being terminated shall bear all
reasonable out-of-pocket costs of a master servicing transfer, including but
not limited to those of the Indenture Trustee, legal fees and expenses,
accounting and financial consulting fees and expenses, and costs of amending
the Agreement, if necessary. In addition, if during the period that the
Depositor is required to file Exchange Act Reports with respect to the Trust
Fund, the Master Servicer shall fail to observe or perform any of the
obligations that constitute a Limited Exchange Act Reporting Obligation or

                                     147
<PAGE>

the obligations set forth in Section 5.24(a), Section 4.08(a) or Section
11.01(a)(1) and (2), and such failure continues for the lesser of [10]
calendar days or such period in which the applicable Exchange Act Report can
be filed timely (without taking into account any extensions), so long as such
failure shall not have been remedied, the Trust Administrator shall, but only
at the direction of the Depositor, terminate all of the rights and obligations
of the Master Servicer under this Agreement and in and to the Mortgage Loans
and the proceeds thereof, other than its rights as a Noteholder hereunder. The
Depositor shall not be entitled to termintate the rights and obligations of
the Master Servicer if a failure of the Master Servicer to identify a
Subcontractor "participating in the servicing function" within the meaning of
Item 1122 of Regulation AB was the attributable solely to the role or
functions of such Subcontractor with respect to mortgage loans other than the
Mortgage Loans.

      The Indenture Trustee shall be entitled to be reimbursed from the Master
Servicer (or by the Trust Estate, if the Master Servicer is unable to fulfill
its obligations hereunder) for all costs associated with the transfer of
servicing from the predecessor Master Servicer, including, without limitation,
any costs or expenses associated with the complete transfer of all servicing
data and the completion, correction or manipulation of such servicing data as
may be required by the Indenture Trustee to correct any errors or
insufficiencies in the servicing data or otherwise to enable the Indenture
Trustee to master service the Mortgage Loans properly and effectively. If the
terminated Master Servicer does not pay such reimbursement within [thirty]
days of its receipt of an invoice therefor, such reimbursement shall be an
expense of the Trust Estate and the Indenture Trustee shall be entitled to
withdraw such reimbursement from amounts on deposit in the Collection Account
pursuant to Section 5.08(ix); provided that the terminated Master Servicer
shall reimburse the Trust Estate for any such expense incurred by the Trust
Estate; and provided, further, that the Indenture Trustee shall take such
action, if any, as provided in the Indenture and as directed by the
Noteholders pursuant thereto with respect to pursuing any remedy against any
party obligated to make such reimbursement.

      Notwithstanding the termination of its activities as Master Servicer,
each terminated Master Servicer shall continue to be entitled to reimbursement
to the extent provided in Section 5.08 to the extent such reimbursement
relates to the period prior to such Master Servicer's termination.

      If any Master Servicer Event of Default shall occur, of which a
Responsible Officer of the Indenture Trustee has actual knowledge, the
Indenture Trustee shall promptly notify each Rating Agency and the Depositor
of the nature and extent of such Master Servicer Event of Default. The Trust
Administrator or the Master Servicer shall immediately give written notice to
the Indenture Trustee upon the Master Servicer's failure to remit Advances on
the date specified herein.

      In the event that the Indenture Trustee assumes the duties of the Master
Servicer as set forth herein, the Indenture Trustee shall provide the
Depositor in writing and in form and substance reasonably satisfactory to the
Depositor, all information reasonably requested by the Depositor in order to
comply with its reporting obligation under Item 6.02 of Form 8-K with respect
to a successor master servicer.

                                     148
<PAGE>

      (b) On and after the time the Master Servicer receives a notice of
termination from the Indenture Trustee pursuant to Section 8.01(a) or the
Indenture Trustee receives the resignation of the Master Servicer evidenced by
an Opinion of Counsel pursuant to Section 5.27, the Indenture Trustee, unless
another master servicer shall have been appointed, shall be the successor in
all respects to the Master Servicer in its capacity as such under this
Agreement and the transactions set forth or provided for herein and shall have
all the rights and powers and be subject to all the responsibilities, duties
and liabilities relating thereto and arising thereafter placed on the Master
Servicer hereunder, including the obligation to make Advances; provided,
however, that any failure to perform such duties or responsibilities caused by
the Master Servicer's failure to provide information required by this
Agreement shall not be considered a default by the Indenture Trustee
hereunder. In addition, the Indenture Trustee shall have no responsibility for
any act or omission of the Master Servicer prior to the issuance of any notice
of termination and shall have no liability relating to the representations and
warranties of the Master Servicer set forth in Section 5.01. In the Indenture
Trustee's capacity as such successor, the Indenture Trustee shall have the
same limitations on liability herein granted to the Master Servicer. As
compensation therefor, the Indenture Trustee shall be entitled to receive all
compensation payable to the Master Servicer under this Agreement.

      (c) Notwithstanding the above, the Indenture Trustee may, if it shall be
unwilling to continue to so act, or shall, if it is unable to so act, appoint,
or petition a court of competent jurisdiction to appoint, any established
housing and home finance institution servicer, master servicer, servicing or
mortgage servicing institution having a net worth of not less than
$[15,000,000] and meeting such other standards for a successor master servicer
as are set forth in this Agreement, as the successor to such Master Servicer
in the assumption of all of the responsibilities, duties or liabilities of a
master servicer, like the Master Servicer. Such successor Master Servicer may
be an Affiliate of the Indenture Trustee; provided, however, that, unless such
Affiliate meets the net worth requirements and other standards set forth
herein for a successor master servicer, the Indenture Trustee, in its
individual capacity shall agree, at the time of such designation, to be and
remain liable to the Issuer and the Indenture Trustee for such Affiliate's
actions and omissions in performing its duties hereunder. In connection with
such appointment and assumption, the Indenture Trustee may make such
arrangements for the compensation of such successor out of payments on the
Mortgage Loans as it and such successor shall agree; provided, however, that
no such compensation shall be in excess of that permitted to the Master
Servicer hereunder. The Indenture Trustee and such successor shall take such
actions, consistent with this Agreement, as shall be necessary to effectuate
any such succession and may make other arrangements with respect to the
servicing to be conducted hereunder which are not inconsistent herewith. The
Master Servicer shall cooperate with the Indenture Trustee and any successor
master servicer in effecting the termination of the Master Servicer's
responsibilities and rights hereunder including, without limitation, notifying
the Servicer of the assignment of the master servicing functions and providing
the Indenture Trustee and successor master servicer, as applicable, all
documents and records in electronic or other form reasonably requested by it
to enable it to assume the Master Servicer's functions hereunder and the
transfer to the Indenture Trustee or such successor master servicer, as
applicable, all amounts or investment property which shall at the time be or
should have been deposited by the Master Servicer in the Collection Account
and any other account or fund maintained with respect to the Notes or
thereafter be received with respect to the Mortgage Loans. Neither the
Indenture Trustee nor any other successor master servicer shall be deemed to
be in default hereunder by

                                     149
<PAGE>

reason of any failure to make, or any delay in making, any payment hereunder
or any portion thereof caused by (i) the failure of the Master Servicer to
deliver, or any delay in delivering, cash, documents or records to it, (ii)
the failure of the Master Servicer to cooperate as required by this Agreement,
(iii) the failure of the Master Servicer to deliver the Mortgage Loan data to
the Indenture Trustee as required by this Agreement or (iv) restrictions
imposed by any regulatory authority having jurisdiction over the Master
Servicer.

      As a condition to any such succession, such successor master servicer
shall provide to the Depositor in writing and in form and substance reasonably
satisfactory to the Depositor, all information reasonably requested by the
Depositor in order to comply with its reporting obligation under Item 6.02 of
Form 8-K with respect to a successor master servicer.

      Section 8.02. Additional Remedies of Indenture Trustee Upon Master
Servicer Event of Default. During the continuance of any Master Servicer Event
of Default, so long as such Master Servicer Event of Default shall not have
been remedied, the Indenture Trustee, in addition to the rights specified in
Section 8.01, shall have the right, in its own name and as trustee of an
express trust, to take all actions now or hereafter existing at law, in equity
or by statute to enforce its rights and remedies and to protect the interests,
and enforce the rights and remedies, of the Noteholders (including the
institution and prosecution of all judicial, administrative and other
proceedings and the filings of proofs of claim and debt in connection
therewith). Except as otherwise expressly provided in this Agreement, no
remedy provided for by this Agreement shall be exclusive of any other remedy,
and each and every remedy shall be cumulative and in addition to any other
remedy, and no delay or omission to exercise any right or remedy shall impair
any such right or remedy or shall be deemed to be a waiver of any Master
Servicer Event of Default.

      Section 8.03. Waiver of Defaults. The Majority Noteholders may, on
behalf of all Noteholders, waive any default or Master Servicer Event of
Default by the Master Servicer in the performance of its obligations
hereunder, except that a default in the making of any required deposit to the
Collection Account that would result in a failure of the Trust Administrator
or the Paying Agent to make any required payment of principal of or interest
on the Notes may only be waived with the consent of [100]% of the affected
Noteholders. Notwithstanding the foregoing, in the event of a Master Servicer
Event of Default related to the obligations set forth in Section 5.24, Section
4.08(a) (with respect to notice to the Depositor) and Article XI, only the
Depositor may waive such Master Servicer Event of Default. Upon any waiver of
a past default, such default shall cease to exist, and any Master Servicer
Event of Default arising therefrom shall be deemed to have been remedied for
every purpose of this Agreement. No such waiver shall extend to any subsequent
or other default or impair any right consequent thereon except to the extent
expressly so waived.

      Section 8.04. Notification to Holders. Upon termination of the Master
Servicer or appointment of a successor to the Master Servicer, in each case as
provided herein, the Indenture Trustee shall promptly mail notice thereof by
first class mail to the Noteholders at their respective addresses appearing on
the applicable Register. The Indenture Trustee shall also, within [45] days
after the occurrence of any Master Servicer Event of Default known to the
Indenture Trustee, give written notice thereof to Noteholders, unless such
Master Servicer Event

                                     150
<PAGE>

of Default shall have been cured or waived prior to the issuance of such
notice and within such [45] day period.

      Section 8.05. Directions by Noteholders and Duties of Indenture Trustee
During Master Servicer Event of Default. During the continuance of any Master
Servicer Event of Default, the Majority Noteholders may direct the time,
method and place of conducting any proceeding for any remedy available to the
Indenture Trustee, or exercising any trust or power conferred upon the
Indenture Trustee, under this Agreement; provided, however, that the Indenture
Trustee shall be under no obligation to pursue any such remedy, or to exercise
any of the trusts or powers vested in it by this Agreement (including, without
limitation, (i) the conducting or defending of any administrative action or
litigation hereunder or in relation hereto and (ii) the terminating of the
Master Servicer or any successor master servicer from its rights and duties as
master servicer hereunder) at the request, order or direction of any of the
Noteholders, unless such Noteholders shall have offered to the Indenture
Trustee security or indemnity reasonably satisfactory to it against the cost,
expenses and liabilities which may be incurred therein or thereby; and,
provided further, that, the Indenture Trustee shall have the right to decline
to follow any such direction if the Indenture Trustee, in accordance with an
Opinion of Counsel, determines that the action or proceeding so directed may
not lawfully be taken or if the Indenture Trustee in good faith determines
that the action or proceeding so directed would involve it in personal
liability for which it is not indemnified to its satisfaction or be unjustly
prejudicial to the non assenting Noteholders.

      Section 8.06. Action Upon Certain Failures of the Master Servicer and
Upon Master Servicer Event of Default. In the event that a Responsible Officer
of the Indenture Trustee or the Trust Administrator shall have actual
knowledge of any action or inaction of the Master Servicer that would become a
Master Servicer Event of Default upon the Master Servicer's failure to remedy
the same after notice, the Indenture Trustee or Trust Administrator, as
applicable, shall give notice thereof to the Master Servicer.

                                  ARTICLE IX

                                  TERMINATION

      Section 9.01. Termination. The respective obligations and
responsibilities of the Master Servicer, the Trust Administrator, the
Depositor, the Issuer, the Servicer and the Indenture Trustee created hereby
(other than obligations expressly stated to survive the termination of the
Trust) shall terminate on the day after the day on which the Notes are paid in
full (including payment pursuant to Section 9.02 below) (the "Termination
Date").

      Section 9.02. Termination Prior to Maturity Date; Optional Redemption.

      (a) On the Payment Date following the Determination Date on which the
Aggregate Collateral Balance is less than [20]% of the Aggregate Collateral
Balance as of the Cut-off Date, _____________________________ acting directly
or through one or more Affiliates, shall have the option to purchase the
Mortgage Loans, any REO Property and any other property remaining in the Trust
for a price equal to the Termination Price. The Master Servicer and the
Servicer will be reimbursed from the Termination Price for any outstanding
Advances, Servicing Advances

                                     151
<PAGE>

and unpaid Servicing Fees, Master Servicing Fees and other amounts not
previously reimbursed pursuant to the provisions of this Agreement, as
applicable, and the Trust Administrator, the Owner Trustee and the Indenture
Trustee (including in its capacity as Custodian, if applicable) shall be
reimbursed for any previously unreimbursed amounts for which they are entitled
to be reimbursed pursuant to this Agreement, the Indenture, the Custodial
Agreement (to the extent not paid by the Seller pursuant to the Custodial
Agreement) or the Trust Agreement, as applicable. If such option is exercised,
the Trust will be terminated resulting in a mandatory redemption of the Notes.
_____________________ shall deliver written notice of its intention to
exercise such option to the Issuer, the Trust Administrator, the Indenture
Trustee and the Master Servicer not less than [15] days prior to the
applicable Payment Date. If _____________________ fails to exercise such
option prior to the Stepup Date, the Note Interest Rate for each class of
Notes will be increased as set forth herein beginning on the Stepup Date and
for each Payment Date thereafter. _____________________ shall deliver written
notice of its intention to exercise such option to the Issuer, the Indenture
Trustee and the Master Servicer not less than [ten] days prior to the
applicable Payment Date.

      In connection with such purchase, _____________________ shall direct the
Servicer to remit to the Trust Administrator all amounts then on deposit in
the Custodial Account (other than amounts permitted to be withdrawn by it
pursuant to Section 4.02(e)) for deposit to the Collection Account.

      (b) In addition, if ______________________ does not exercise its
purchase option pursuant to subsection (a) of this Section 9.02, then, on the
Payment Date following the Determination Date on which the Aggregate
Collateral Balance is less than [10]% of the Aggregate Collateral Balance as
of the Cut-off Date, the Servicer acting directly or through one or more
Affiliates, shall have the option to purchase the Mortgage Loans, any REO
Property and any other property remaining in the Trust for a price equal to
the Termination Price. All conditions applying to _____________________'s
right to purchase the Mortgage Loans pursuant to paragraph (a) above shall
also apply to the Servicer's right.

      (c) Promptly following any such purchase pursuant to paragraph (a) or
(b) of this Section and receipt of an Officer's Certificate of
_____________________ or of the Servicer, as applicable, that the purchase
price has been deposited in the Collection Account, the Indenture Trustee or
the applicable Custodian shall release the Mortgage Files to the purchaser of
such Mortgage Loans pursuant to this Section 9.02, or otherwise upon its
order.

      Section 9.03. Certain Notices upon Final Payment. The Master Servicer or
the Trust Administrator, as applicable, shall give the Issuer, the Indenture
Trustee, the Owner Trustee, each Rating Agency, each Noteholder and the
Depositor at least [30] days' prior written notice of the date on which the
Trust is expected to terminate in accordance with Section 9.01, or the date on
which the Notes will be redeemed in accordance with Section 9.02. Not later
than the [fifth] Business Day in the Collection Period in which the final
payment in respect to the Notes is payable to the Noteholders, the Indenture
Trustee shall mail to the Noteholders a notice specifying the procedures with
respect to such final payment. The Trust Administrator on behalf of the
Indenture Trustee shall give a copy of such notice to each Rating Agency at
the time such notice is given to Noteholders. Following the final payment
thereon, such Notes shall become

                                     152
<PAGE>

void, no longer outstanding and no longer evidence any right or interest in
the Mortgage Loans, the Mortgage Files or any proceeds of the foregoing.

                                  ARTICLE X

                           MISCELLANEOUS PROVISIONS

      Section 10.01. Binding Nature of Agreement; Assignment. This Agreement
shall be binding upon and inure to the benefit of the parties hereto and their
respective successors and permitted assigns.

      Section 10.02. Entire Agreement. This Agreement contains the entire
agreement and understanding among the parties hereto with respect to the
subject matter hereof, and supersedes all prior agreements, understandings,
inducements and conditions, express or implied, oral or written, of any nature
whatsoever with respect to the subject matter hereof. The express terms hereof
control and supersede any course of performance and/or usage of the trade
inconsistent with any of the terms hereof.

      Section 10.03. Amendment.

      (a) This Agreement may be amended from time to time by the parties
hereto, without notice to or the consent of any of the Holders of the Notes,
(i) to cure any ambiguity, (ii) to conform the provisions of this Agreement to
the information contained in the Prospectus or to correct or supplement any
provision herein, (iii) to make any other provision with respect to matters or
questions arising under this Agreement or (iv) to add, delete, or amend any
provision in order to comply with any requirements imposed by the Code, ERISA
and their related regulations. No such amendment effected pursuant to the
preceding sentence shall, as evidenced by an Opinion of Counsel (which shall
be an expense of the party requesting such amendment and shall not be an
expense of the Trust or the Indenture Trustee), (1) affect the status of the
Notes as debt for federal income tax purposes or (2) only in the case of an
amendment effected pursuant to clause (iii) of such sentence, adversely affect
in any material respect the interests of any Holder. Prior to entering into
any amendment without the consent of Holders pursuant to this paragraph, the
Indenture Trustee may require an Opinion of Counsel (at the expense of the
party requesting such amendment) to the effect that such amendment is
permitted under this paragraph. Any such amendment shall be deemed not to
adversely affect in any material respect any Holder, if the Indenture Trustee
receives written confirmation from each Rating Agency that such amendment will
not cause such Rating Agency to reduce the then current ratings assigned to
the Notes.

      (b) This Agreement may also be amended from time to time by the parties
hereto with the consent of (i) the Holders of each Class of Notes affected
thereby evidencing Voting Interests aggregating not less than [66-2/3]% of
each such Class and (ii) the Holder of the Ownership Certificate, for the
purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of this Agreement or modifying in any manner the rights
of Noteholders; provided, however, that no such amendment may (i) reduce in
any manner the amount of, or delay the timing of, payments that are required

      a statement to that effect. The Depositor and the Master Servicer, and
      each of their respective officers and directors shall be entitled to
      rely on upon each such servicing criteria assessment.

            (2) Each of the Master Servicer, the Servicer, the Trust
      Administrator, the Custodian and the [Indenture Trustee] shall deliver
      to the Depositor and the Master Servicer a report of a registered public
      accounting firm reasonably acceptable to the Depositor that attests to,
      and reports on, the assessment of compliance made by Master Servicer,
      the Servicer, the Trust Administrator, the Custodian or the [Indenture
      Trustee], as applicable, and delivered pursuant to the preceding
      paragraphs. Such attestation shall be in accordance with Rules
      1-02(a)(3) and 2-02(g) of Regulation S-X under the Securities Act and
      the Exchange Act, including, without limitation that in the event that
      an overall opinion cannot be expressed, such registered public
      accounting firm shall state in such report why it was unable to express
      such an opinion. Such report must be available for general use and not
      contain restricted use language. To the extent any of the Servicing
      Criteria are not applicable to such Person, with respect to asset-backed
      securities transactions taken as a whole involving such Person and that
      are backed by the same asset type backing the Notes, such report shall
      include such a statement to that effect.

      accountant's attestation as and when provided in paragraphs (a) and (b)
      of this Section.

            (5) The Master Servicer, the Servicer, the Trust Administrator,
      the Custodian and the [Indenture Trustee] shall execute (and the
      Servicer and the Master Servicer shall cause each related Subservicer to
      execute, and the Master Servicer, the Servicer, the Trust Administrator,
      the Custodian and the [Indenture Trustee] shall cause each Reporting
      Subcontractor to execute) a reliance certificate to enable the
      Certification Parties to rely upon each (i) annual compliance statement
      provided pursuant to Section 5.24, (ii) annual report on assessments of
      compliance with servicing criteria provided pursuant to this Section
      11.07 and (iii) accountant's report provided pursuant to this Section
      11.07 and shall include a certification that each such annual compliance
      statement or report discloses any deficiencies or defaults described to
      the registered public accountants of such Person to enable such
      accountants to render the Notes provided for in this Section 11.07. In
      the event the Master Servicer, the Servicer, any Subservicer, the Trust
      Administrator, the Custodian or Reporting Subcontractor is terminated or
      resigns during the term of this Agreement, such Person shall provide a
      certification to the Certifying Person pursuant to this Section 11.07
      with respect to the period of time it was subject to this Agreement or
      provided services with respect to the Trust Fund, the Notes or the
      Mortgage Loans.

      (b) Each assessment of compliance provided by a Subservicer pursuant to
Section 11.07(a)(3) shall address each of the Servicing Criteria specified on
a certification substantially in the form of Exhibit J hereto delivered to the
Depositor concurrently with the execution of this Agreement or, in the case of
a Subservicer subsequently appointed as such, on or prior to the date of such
appointment. An assessment of compliance provided by a Subcontractor pursuant
to Section 11.07(a)(3) or (4) need not address any elements of the Servicing
Criteria other than those specified by the Master Servicer, the Servicer, the
Trust Administrator, the Custodian or the [Indenture Trustee], as applicable,
pursuant to Section 11.07(a)(1).

      Section 11.08. Use of Subservicers and Subcontractors.

      (a) Each of the Master Servicer and the Servicer shall cause any
Subservicer used by the Servicer (or by any Subservicer), respectively, for
the benefit of the Depositor to comply with the provisions of Section 5.24 and
Section 4.04(e), respectively, and this Article XI to the same extent as if
such Subservicer were the Servicer or the Master Servicer, as the case may be
(except with respect to the Master Servicer's duties with respect to preparing
and filing any Exchange Act Reports or as the Certifying Person). Each of the
Master Servicer and the Servicer shall be responsible for obtaining from each
related Subservicer and delivering to the Depositor any servicer compliance
statement required to be delivered by such Subservicer under Section

                                     163
<PAGE>

5.24 and Section 4.04(e), respectively, any assessment of compliance and
attestation required to be delivered by such Subservicer under Section 11.07
and any certification required to be delivered to the Certifying Person under
Section 11.05 as and when required to be delivered. As a condition to the
succession to any Subservicer as subservicer under this Agreement by any
Person (i) into which such Subservicer may be merged or consolidated, or (ii)
which may be appointed as a successor to any Subservicer, the Servicer shall
provide to the Depositor, at least 15 calendar days prior to the effective
date of such succession or appointment, (x) written notice to the Depositor of
such succession or appointment and (y) in writing and in form and substance
reasonably satisfactory to the Depositor, all information reasonably requested
by the Depositor in order to comply with its reporting obligation under Item
6.02 of Form 8-K.

      (b) It shall not be necessary for the Master Servicer, the Servicer, any
Subservicer, the Trust Administrator, the Custodian or the [Indenture Trustee]
to seek the consent of the Depositor or any other party hereto to the
utilization of any Subcontractor. The Master Servicer, the Servicer, the Trust
Administrator, the Custodian or the [Indenture Trustee], as applicable, shall
promptly upon request provide to the Depositor (or any designee of the
Depositor, such as the Servicer or administrator) a written description (in
form and substance satisfactory to the Depositor) of the role and function of
each Subcontractor utilized by such Person (or in the case of the Servicer or
the Master Servicer, any Subservicer), specifying (i) the identity of each
such Subcontractor, (ii) which (if any) of such Subcontractors are
"participating in the servicing function" within the meaning of Item 1122 of
Regulation AB, and (iii) which elements of the Servicing Criteria will be
addressed in assessments of compliance provided by each Subcontractor
identified pursuant to clause (ii) of this paragraph.

            As a condition to the utilization of any Subcontractor determined
to be a Reporting Subcontractor, the Master Servicer, the Servicer, the Trust
Administrator, the Custodian or the [Indenture Trustee], as applicable, shall
cause any such Subcontractor used by such Person (or in the case of the
Servicer or the Master Servicer, any Subservicer) for the benefit of the
Depositor to comply with the provisions of Sections 11.07 and 11.09 of this
Agreement to the same extent as if such Subcontractor were the Master
Servicer, the Servicer, the Trust Administrator, the Custodian or the
[Indenture Trustee], as applicable (except with respect to the Master
Servicer's duties with respect to preparing and filing any Exchange Act
Reports or as the Certifying Person). The Master Servicer, the Servicer, the
Trust Administrator, the Custodian or the [Indenture Trustee], as applicable,
shall be responsible for obtaining from each Subcontractor and delivering to
the Depositor and the Master Servicer, any assessment of compliance and
attestation required to be delivered by such Subcontractor under Section
11.07, in each case as and when required to be delivered.

      Section 11.09. Amendments.

            In the event the parties to this Agreement desire to further
clarify or amend any provision of this Article XI, this Agreement shall be
amended to reflect the new agreement between the parties covering matters in
this Article XI pursuant to Section 10.03, which amendment shall not require
any Opinion of Counsel or Rating Agency confirmations or the consent of any
Noteholder.

                                     164
<PAGE>

      If, during the period that the Depositor is required to file Exchange
Act Reports with respect to the Trust Fund, the Master Servicer is no longer
an Affiliate of the Depositor, the Depositor shall assume the obligations and
responsibilities of the Master Servicer in this Article XI with respect to the
preparation and filing of the Exchange Act Reports and/or acting as the
Certifying Person, if the Depositor has received indemnity from such successor
Master Servicer satisfactory to the Depositor, and such Master Servicer has
agreed to provide a Sarbanes-Oxley Certification to the Depositor
substantially in the form of Exhibit M.

         6.     Capitalized terms used herein and not defined herein shall
have the meanings assigned to them in the Sale and Servicing Agreement.

                                   AGREEMENT

         NOW THEREFORE, in consideration of the mutual promises herein made
and other good and valuable consideration, the receipt and adequacy of which
are hereby acknowledged, the parties hereto hereby agree as follows:

         1.       Purchase and Sale of Mortgage Loans.

                  (a) Concurrently with the execution and delivery hereof on
________, 200_ (the "Closing Date"), the Seller hereby sells, assigns,
transfers and otherwise conveys to the Purchaser, without recourse, all of its
right, title and interest (other than any servicing rights relating to the
Mortgage Loans) in and to the Mortgage Loans, including all interest and
principal received on or with respect to the Mortgage Loans on or after the
Cut-off Date (other than any such payments that were due on or prior to such
date) and all payments due after such date but received prior to such date and
intended by the related Mortgagors to be applied after such date, together
with all of the Seller's right, title and interest in and to any related
escrow account and all amounts from time to time credited to and the proceeds
of such account, the Seller's rights under any insurance policies related to
the Mortgage Loans and the proceeds thereof and the Seller's security interest
in any collateral pledged to secure the Mortgage Loans, including the
Mortgaged Properties.

                  (b) The Seller further agrees, at its own expense, on or
prior to the Closing Date, (i) to indicate in its books and records that the
Mortgage Loans have been sold to the Issuer, as assignee of the Purchaser and
(ii) to deliver to the Purchaser a data file in the form of Schedule I
containing a true and complete list of all such Mortgage Loans (the "Mortgage
Loan Schedule"). The Mortgage Loan Schedule shall conform to the requirements
set forth in this Agreement and to the definition of "Mortgage Loan Schedule"
in the Sale and Servicing Agreement. In connection with such transfer and
assignment of the Mortgage Loans hereunder, the Seller does hereby deliver, or
cause to be delivered, to the Purchaser (or its designee) each Mortgage File
relating to the Mortgage Loans in the manner set forth in Section 2.01 of the
Sale and Servicing Agreement. In the case of Mortgage Loans (if any) that have
been prepaid in full after the Cut-off Date and prior to the execution of this
Agreement, the Seller, in lieu of delivering the related Mortgage Files, shall
herewith deliver to the Purchaser an Officer's Certificate which shall include
a statement to the effect that all amounts received in connection with such
prepayment that are required to be deposited in the Collection Account have
been so deposited. The Seller hereby covenants not to take any action
inconsistent with the ownership interest of the Purchaser or its assignee and
any subsequent assignee or pledgee in the Mortgage Files.

                  (c) The Purchaser and the Seller intend that on the Closing
Date the conveyance by the Seller to the Purchaser of all its right, title and
interest in and to the Mortgage Loans pursuant to this Agreement shall be, and
be construed as, a sale of the Mortgage Loans, without recourse. It is,
further, not intended that such conveyance be deemed to be a pledge of the
Mortgage Loans by the Seller to the Purchaser to secure a debt or other
obligation of the

                                      2
<PAGE>

Seller. However, in the event that the Mortgage Loans are held to be property
of the Seller, or if this Agreement is held or deemed to create a security
interest in the Mortgage Loans, then it is intended that (i) this Agreement
shall also be deemed to be a security agreement within the meaning of Articles
8 and 9 of the New York Uniform Commercial Code and the Uniform Commercial
Code of any other applicable jurisdiction; (ii) the conveyances provided for
in this Section 1 shall be deemed to be a grant by the Seller to the
Purchaser, to secure payment in full of the Secured Obligations (as defined
below), of a security interest in all of the Seller's right (including the
power to convey title thereto), title and interest, whether now owned or
hereafter acquired, in and to the Mortgage Loans, including without limitation
the Mortgage Notes, the Mortgages, any related insurance policies, the
Seller's security interest in any collateral pledged to secure the Mortgage
Loans with respect to the Mortgage Loans and all other documents in the
related Mortgage Files, and all accounts, general intangibles, chattel paper,
instruments, documents, money, deposit accounts, certificates of deposit,
goods, letters of credit, advices of credit and investment property
constituting part of the assets of the Trust, arising from or relating to (A)
the Mortgage Loans (other than any servicing rights relating to the Mortgage
Loans), including with respect to each Mortgage Loan, the Mortgage Note and
related Mortgage, and all other documents in the related Mortgage Files, and
including any Qualifying Substitute Mortgage Loans; (B) pool insurance
policies, hazard insurance policies and any bankruptcy bond relating to the
foregoing, if applicable; (C) all amounts payable on or after the Cut-off Date
(other than any such payments that were due on or prior to such date) to the
holders of the Mortgage Loans in accordance with the terms thereof; (D) all
income, payments, proceeds and products of the conversion, voluntary or
involuntary, of the foregoing into cash, instruments, securities or other
property; and (E) all cash and non-cash proceeds of any of the foregoing;
(iii) the possession or control by the Indenture Trustee or any agent of the
Indenture Trustee of Mortgage Notes or such other items of property as
constitute instruments, money, documents, advices of credit, letters of
credit, goods, certificated securities or chattel paper shall be deemed to be
possession or control by the secured party, or possession or control by the
Purchaser, for purposes of perfecting the security interest pursuant to the
Uniform Commercial Code (including, without limitation, Sections 9-312 or
9-313 thereof); and (iv) notifications to persons holding such property, and
acknowledgments, receipts or confirmations from persons holding such property,
shall be deemed notifications to, or acknowledgements, receipts or
confirmations from, securities intermediaries, bailees or agents of, or
persons holding for, the Indenture Trustee, as applicable, for the purpose of
perfecting such security interest under applicable law. "Secured Obligations"
means the rights of the Purchaser under this Agreement. The Seller shall, to
the extent consistent with this Agreement, take such reasonable actions as may
be necessary to ensure that, if this Agreement were deemed to create a
security interest in the Mortgage Loans and the other property described
above, such security interest would be deemed to be a perfected security
interest of first priority under applicable law and would be maintained as
such throughout the term of this Agreement. Without limiting the generality of
the foregoing, the Seller shall prepare and deliver to the Purchaser at least
two months prior to any filing date, and the Purchaser shall file, or shall
cause to be filed, at the expense of the Seller, all filings necessary to
maintain the effectiveness of any original filings necessary under the Uniform
Commercial Code as in effect in any jurisdiction to perfect the Purchaser's
security interest in or lien on the Mortgage Loans.

         Notwithstanding the foregoing provisions of this Section 1, (i) the
Seller, as a servicer of the Mortgage Loans, shall retain the servicing rights
(including, without limitation, primary

                                      3
<PAGE>

servicing) with respect to the Mortgage Loans, and rights to receive servicing
fees, servicing income, reimbursement for advances made in respect of such
Mortgage Loans and other payments made as compensation for such servicing
subject to the Sale and Servicing Agreement pursuant to the terms and
conditions set forth therein (collectively, the "Servicing Rights") and (ii)
the Servicing Rights are not included in the collateral in which the Seller
grants a security interest in favor of the Purchaser pursuant to the
immediately preceding paragraph, nor are the Servicing Rights included in the
assets being sold pursuant to this Agreement.

                  (d) In consideration of the sale of the Mortgage Loans from
the Seller to the Purchaser on the Closing Date, the Purchaser agrees on the
Closing Date (i) to pay to the Seller by transfer of immediately available
funds, an amount equal to $_______________, which is net of (A) an amount of
$___________ representing the current Securities and Exchange Commission
registration statement fees for the amount of Notes issued on the Closing Date
and offered publicly pursuant to the Prospectus and (B) the underwriting
discount, (ii) to deliver to the Seller the [Class B] and [Class P] Notes and
(iii) to transfer to the Seller or one of its Affiliates on the Closing Date
the Ownership Certificate (together, the "Purchase Price"). The Seller shall
pay, and be billed directly for, all expenses incurred by the Purchaser in
connection with the issuance of the Notes, including, without limitation,
upfront payments due to the Cap Counterparty in respect of the Interest Rate
Cap Agreements, printing fees incurred in connection with the prospectus
relating to the Notes, blue sky registration fees and expenses, fees and
expenses of Sidley Austin LLP, fees of the rating agencies requested to rate
the Notes, accountant's fees and expenses, Custodian fees, loan level due
diligence fees, the fees and expenses of the Indenture Trustee and the Owner
Trustee, the fees (other than any fees to which the Master Servicer is
entitled pursuant to the Sale and Servicing Agreement) and expenses of the
Master Servicer and Trust Administrator and other out-of-pocket costs, if any.

         2. Representations and Warranties.

                  (a) The Seller hereby represents and warrants to the
Purchaser that, as of the date of this Agreement:

                           (i) The Company is a ___________, duly organized
         validly existing and in good standing under the laws of the
         _______________, and has the corporate power to own its assets and to
         transact the business in which it is currently engaged. The Company
         is duly qualified to do business as a foreign corporation and is in
         good standing in each jurisdiction in which the character of the
         business transacted by it or any properties owned or leased by it
         requires such qualification and in which the failure so to qualify
         would have a material adverse effect on the business, properties,
         assets, or condition (financial or other) of the Company;

                           (ii) The Company has the corporate power and
         authority to make, execute, deliver and perform this Agreement and
         all of the transactions contemplated under this Agreement, and has
         taken all necessary corporate action to authorize the execution,
         delivery and performance of this Agreement. When executed and
         delivered, this Agreement will constitute the legal, valid and
         binding obligation of the Company enforceable in accordance with its
         terms, except as enforcement of such terms may be

                                      4
<PAGE>

         limited by bankruptcy, insolvency or similar laws affecting the
         enforcement of creditors' rights generally and by the availability of
         equitable remedies;

                           (iii) [The Company has been organized in conformity
         with the requirements for qualification as a REIT; the Company has
         filed an election to be treated as a REIT for federal income tax
         purposes; and the Company currently qualifies as, and it proposes to
         operate in a manner that will enable it to continue to qualify as, a
         REIT;]

                           (iv) The consummation of the transactions
         contemplated by this Agreement are in the ordinary course of business
         of the Company, and the transfer, assignment and conveyance of the
         Mortgage Notes and the Mortgages by the Company pursuant to this
         Agreement are not subject to the bulk transfer or any similar
         statutory provisions in effect in any applicable jurisdiction;

                           (v) Neither the execution and delivery of this
         Agreement, the sale of the Mortgage Loans to the Purchaser or the
         transactions contemplated hereby, nor the fulfillment of or
         compliance with the terms and conditions of this Agreement will
         conflict with or result in a breach of any of the terms, articles of
         incorporation or by-laws, or constitute a default or result in the
         violation of any law, rule, regulation, order, judgment or decree to
         which the Company or its property is subject, or constitute a default
         under or result in the acceleration of payment under any material
         agreement, indenture or loan or credit agreement or other material
         instrument to which the Company or its property are subject;

                           (vi) The Company does not believe, nor does it have
         any reason or cause to believe, that it cannot perform each and every
         covenant contained in this Agreement. The Company is solvent and the
         sale of the Mortgage Loans will not cause the Company to become
         insolvent. The sale of the Mortgage Loans is not undertaken to
         hinder, delay or defraud any of the Company's creditors;

                           (vii) Other than those matters which are disclosed
         in the Prospectus Supplement under the caption "Risk
         Factors--______________________," there is no action, suit,
         proceeding or investigation pending or, to the knowledge of the
         Seller, threatened against the Company which, either in any one
         instance or in the aggregate, may result in any material adverse
         change in the business, operations, financial condition, properties
         or assets of the Company, or in any material impairment of the right
         or ability of the Company to carry on its business substantially as
         now conducted, or in any material liability on the part of the
         Company, or which would draw into question the validity of this
         Agreement or the Mortgage Loans or of any action taken or to be
         contemplated herein, or which would be likely to impair materially
         the ability of the Company to perform under the terms of this
         Agreement;

                           (viii) No consent, approval, authorization or order
         of any court or governmental agency or body is required for the
         execution, delivery and performance by the Company of or compliance
         by the Company with this Agreement or the sale of the Mortgage Loans
         as evidenced by the consummation of the transactions contemplated by
         this Agreement, or if required, such approval has been obtained prior
         to the Closing Date;

                                      5
<PAGE>

                           (ix) The selection of the Mortgage Loans was not
         made in a manner so as to affect adversely the interests of the
         Purchaser;

                           (x) Neither this Agreement nor any statement,
         report or other document furnished or to be furnished pursuant to
         this Agreement or in connection with the transactions contemplated
         hereby contains any untrue statement of fact;

                           (xi) There has been no change in the business,
         operations, financial condition or assets of the Company since
         ____________, 200_, that would have a material adverse effect on its
         ability to perform its obligations under this Agreement or the Sale
         and Servicing Agreement;

                           (xii) The Company has not dealt with any broker,
         investment banker, agent or other Person (other than the
         Underwriters) that may be entitled to any commission or compensation
         in the connection with the sale of the Mortgage Loans;

                           (xiii) The consideration received by the Company
         upon the sale of the Mortgage Loans under this Agreement constitutes
         fair consideration and reasonably equivalent value of the Mortgage
         Loans; and

                           (xiv) The Company has complied with all applicable
         anti-money laundering laws and regulations (the "Anti-Money
         Laundering Laws") and has established an anti-money laundering
         compliance program as required by the Anti-Money Laundering Laws.

                  (b) The Seller hereby makes the representations and
warranties set forth in Schedule II hereto with respect to each Mortgage Loan
and by this reference incorporated herein, to the Purchaser and the Indenture
Trustee, as of the Closing Date or, if applicable, such other date as may be
specified therein. With respect to any of the representations and warranties
made in Schedule II that are made to the best of the Seller's knowledge or as
to which the Seller has no knowledge, if it is discovered by the Purchaser,
the Seller, the Issuer or the Indenture Trustee that the substance of such
representation and warranty is inaccurate and such inaccuracy materially and
adversely affects the value of the related Mortgage Loan or the interest
therein of the Noteholders then, notwithstanding the Seller's lack of
knowledge with respect to the substance of such representation and warranty
being inaccurate at the time the representation or warranty was made, such
inaccuracy shall be deemed a breach of the applicable representation or
warranty.

                  (c) The Purchaser hereby represents and warrants to the
Seller that, as of the date of this Agreement:

                           (i) it is a corporation duly organized, validly
         existing and in good standing under the laws of the State of Delaware
         and has full power and authority to enter into and perform its
         obligations under this Agreement and the Sale and Servicing
         Agreement;

                           (ii) this Agreement and the Sale and Servicing
         Agreement have been duly authorized, executed and delivered by the
         Purchaser and constitute the legal, valid

                                      6
<PAGE>

         and binding agreements of the Purchaser enforceable against the
         Purchaser in accordance with their respective terms, subject to (A)
         bankruptcy, insolvency, receivership, conservatorship,
         reorganization, moratorium or other similar laws affecting creditors'
         rights generally, (B) general principles of equity regardless of
         whether enforcement is sought in a proceeding in equity or at law,
         and (C) public policy considerations limiting the enforceability of
         provisions of this Agreement and the Sale and Servicing Agreement
         which purport to provide indemnification from penalties under
         applicable securities laws;

                           (iii) neither the execution and delivery by the
         Purchaser of this Agreement, nor the performance by the Purchaser of
         the provisions hereof, will (A) conflict with or result in a breach
         of, or constitute a default under, any of the provisions of the
         certificate of incorporation or bylaws of the Purchaser or any law,
         governmental rule or regulation or any judgment, decree or order
         binding on the Purchaser or any of its properties, or any of the
         provisions of any indenture, mortgage, deed of trust, contract or
         other instrument to which the Purchaser is a party or by which it is
         bound, or (B) result in the creation of any lien, charge, or
         encumbrance upon any of its properties pursuant to the terms of any
         such indenture, mortgage, deed of trust, contract or other
         instrument, which, in the case of either (A) or (B), would have a
         material adverse effect on its ability to perform its obligations
         hereunder or on the financial condition of the Purchaser;

                           (iv) there are no actions, suits or proceedings
         against the Purchaser pending or, to the knowledge of the Purchaser,
         threatened, or, to the knowledge of the Purchaser, investigations
         pending, before any court, administrative agency or other tribunal
         (A) asserting the invalidity of this Agreement, (B) seeking to
         prevent the consummation of any of the transactions contemplated by
         this Agreement or (C) which might materially and adversely affect the
         performance by the Purchaser of its obligations under, or the
         validity or enforceability of, this Agreement;

                           (v) the Purchaser is not in violation of its
         certificate of incorporation or bylaws or in default under any
         agreement, indenture or instrument the effect of which default would
         have a material adverse effect on the ability of the Purchaser to
         perform its obligations under this Agreement or on the financial
         condition of the Purchaser;

                           (vi) the Purchaser is not a party to, bound by or
         in breach or violation of any indenture or other agreement or order
         or regulation of any court, regulatory body, administrative agency or
         governmental body having jurisdiction over it that materially and
         adversely affects the (A) ability of the Purchaser to perform its
         obligations under this Agreement or (B) the business, operations,
         financial condition, properties or assets of the Purchaser; and

                           (vii) no consent, approval, authorization or order
         of any federal or state court or governmental agency or body is
         required for the consummation by the Purchaser of the transactions
         contemplated by the terms of this Agreement.

         3. Survival of Representations. Each of the representations and
warranties of the Seller and the Purchaser contained herein shall survive the
purchase and sale of the Mortgage Loans pursuant hereto and shall continue in
full force and effect, notwithstanding any restrictive

                                      7
<PAGE>

or qualified endorsement on the Mortgage Notes and notwithstanding subsequent
termination of this Agreement. The representations and warranties shall not be
impaired by any review and examination of documents to be delivered or held by
the Seller in respect of each Mortgage Loan or other documents evidencing or
relating to the Mortgage Loans or any failure on the part of the Purchaser or
any successor or assignee thereof to review or examine such documents.

         4. Repurchase, Purchase or Substitution of Mortgage Loans.

                  (a) Upon discovery by the Purchaser, the Seller, the Master
Servicer or any assignee, transferee or designee of the Purchaser of a
Material Defect with respect to a Mortgage Loan or a breach of any of the
representations and warranties of the Seller contained in Section 2 of this
Agreement that materially and adversely affects the value of any Mortgage Loan
or the interest therein of the Purchaser or the Purchaser's assignee,
transferee or designee, the party discovering the Material Defect or breach
shall give prompt written notice to the others. Within 90 days of the
discovery of such Material Defect or breach of any representation or warranty
given by the Seller to the Purchaser, the Seller shall either (a) cure such
Material Defect or such breach in all material respects, (b) repurchase such
Mortgage Loan or any property acquired in respect thereof from the Purchaser
for the Purchase Price (as defined in the Sale and Servicing Agreement) or (c)
within the two year period following the Closing Date, substitute a Qualifying
Substitute Mortgage Loan for the affected Mortgage Loan, in accordance with
Sections 2.02 and 3.02 of the Sale and Servicing Agreement, as applicable. If
any substitution is made for a Mortgage Loan for which there is a Material
Defect or breach of any of the representations and warranties which adversely
and materially affects the value of such Mortgage Loan and such substitute
mortgage loan is not a Qualifying Substitute Mortgage Loan, the Seller will,
in exchange for such substitute Mortgage Loan, (i) provide the applicable
Purchase Price (as defined in the Sale and Servicing Agreement) for the
affected Mortgage Loan or (ii) within two years of the Closing Date,
substitute such affected Mortgage Loan with a Qualifying Substitute Mortgage
Loan.

                  (b) It is understood and agreed that the obligations of the
Seller set forth in this Section 4 to cure, repurchase or substitute for a
defective Mortgage Loan (together with its indemnification obligations set
forth in Section 7) constitute the sole remedies of the Purchaser with respect
to a missing or defective document, Material Defect or a breach of any of the
representations or warranties of the Seller contained in Section 2.

         5. Covenants.

                  (a) The Seller hereby covenants that, except for the
transfer hereunder, the Seller will not sell, pledge, assign or transfer to
any other Person, or grant, create, incur, assume or suffer to exist any Lien
on any Mortgage Loan, or any interest therein; the Seller will notify the
Purchaser at its address specified herein and the Indenture Trustee at its
Corporate Trust Office of the existence of any Lien on any Mortgage Loan
immediately upon discovery thereof; and the Seller will defend the right,
title and interest of the Trust Estate, as assignee of the Purchaser, in, to
and under the Mortgage Loans, against all claims of third parties claiming
through or under the Seller; provided, however, that nothing in this Section
shall prevent or be deemed to prohibit the Seller from suffering to exist upon
any of the Mortgage Loans any liens for municipal or other local taxes and
other governmental charges if such taxes or governmental

                                      8
<PAGE>

charges shall not at the time be due and payable or if the Seller shall
currently be contesting the validity thereof in good faith by appropriate
proceedings and shall have set aside on its books adequate reserves with
respect thereto.

                  (b) The Seller hereby covenants to the Purchaser that at any
time when a prospectus relating to the Notes is required to be delivered
pursuant to the Securities Act, if the Seller has knowledge that there has
been a material change affecting the disclosures in the Prospectus Supplement
relating to the Seller or the Mortgage Loans or that such disclosures therein
contain any untrue fact or omit to state a material fact necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading, the Seller promptly will notify the Purchaser of such
change, untrue fact or omission and update the Prospectus Supplement at its
expense subject to the prior written consent of the Purchaser. The Seller also
agrees that, if required by applicable law, it will update the information
relating to the Seller or the Mortgage Loans in the Prospectus Supplement at
its expense, subject to the prior written consent of the Purchaser.

         6. Successors and Assigns, Additional Information.

                  (a) This Agreement shall be binding upon and inure to the
benefit of the parties hereto and their respective successors and assigns. No
party hereto may assign either this Agreement or any of its rights, interests
or obligations hereunder without the prior written approval of the other
parties hereto; provided, however, that the Purchaser may assign its rights
and interests and delegate its obligations hereunder to the Trust and the
Trust may then pledge its rights and interests to the Indenture Trustee, and
the Indenture Trustee then shall succeed to all rights and interests of the
Purchaser under this Agreement without the consent of the other party hereto.

                  (b) The Seller hereby agrees to furnish any and all
information, documents, certificates, letters or opinions with respect to the
Mortgage Loans reasonably requested by the Purchaser in order to perform any
of its obligations or satisfy any of the conditions on its part to be
performed or satisfied pursuant to the Sale and Servicing Agreement or the
Underwriting Agreement.

         7. Indemnification.

                  (a) In addition to any repurchase and cure obligations of
the Seller under this Agreement and any and all other remedies available to
the Purchaser under this Agreement, the Seller shall indemnify and hold
harmless the Purchaser against any and all losses, damages, penalties, fines,
claims, forfeitures, lawsuits, court costs, reasonable attorney's fees,
judgments, and any other costs, fees, and expenses, arising from claims made
or actions brought by any person other than the Purchaser based on or arising
from breach of any warranty, obligation, representation, or covenant contained
in or made by the Seller in writing, pursuant to this Agreement (except as set
forth in Section 2(a)(x) herein) by any agent, employee, representative or
officer of the Seller or any of its affiliates. The Seller shall assume the
defense of any such claim and pay all expenses in connection therewith,
including reasonable counsel fees, and promptly pay, discharge and satisfy any
judgment or decree which may be entered against the Purchaser or any such
person or entity in respect of such claim. It is understood and agreed that

                                      9
<PAGE>

any permitted assignee of the Purchaser (including the Indenture Trustee)
shall be a third party beneficiary of this Agreement. The indemnification
obligations of the Seller hereunder shall survive the termination of this
Agreement.

                  (b) Notwithstanding any other provision of this Agreement,
in connection with the issuance of the Notes, the Seller shall agree to such
modifications and enter into such amendments to this Agreement as may be
necessary, in the reasonable judgment of the Purchaser and its counsel, to
comply with any rules promulgated by the Securities and Exchange Commission
(the "Commission") and any interpretations thereof by the staff of the
Commission (collectively, the "SEC Rules"), with reasonable notice to the

                                  SCHEDULE II

                 MORTGAGE LOAN REPRESENTATIONS AND WARRANTIES

         The Seller hereby represents and warrants to, and covenants with, the
Purchaser that, as to each Mortgage Loan, as of the Closing Date or such other
date specifically set forth herein, and with respect to representation (a)
listed below, as of the Cut-off Date:

                  (a) [Mortgage Loans as Described. The information set forth
in the Mortgage Loan Schedule is complete, true and correct in all material
respects;

                  (b) Payments Current. All payments required to be made up to
and including the Cut-off Date for the Mortgage Loan under the terms of the
Mortgage Note have been made and credited. No payment required under the
Mortgage Loan has been delinquent for 30 days or more in the 12 months
preceding the related Closing Date;

                  (c) No Outstanding Charges. There are no defaults in
complying with the terms of the Mortgage, and all taxes, governmental
assessments, insurance premiums, water, sewer and municipal charges, leasehold
payments or ground rents which previously became due and owing have been paid,
or an escrow of funds has been established in an amount sufficient to pay for
every such item which remains unpaid and which has been assessed but is not
yet due and payable. The Seller has not advanced funds, or induced, solicited
or knowingly received any advance of funds by a party other than the
Mortgagor, directly or indirectly, for the payment of any amount required
under the Mortgage Loan, except for interest accruing from the date of the
Mortgage Note or date of disbursement of the Mortgage Loan proceeds, whichever
is earlier, to the day which precedes by one month the Due Date of the first
installment of principal and interest;

                  (d) Original Terms Unmodified. The terms of the Mortgage
Note and Mortgage have not been impaired, waived, altered or modified in any
respect, except by a written instrument which has been recorded, if necessary
to protect the interests of the Purchaser and which has been delivered to the
Purchaser. The substance of any such waiver, alteration or modification has
been approved by the issuer of any related PMI Policy and the title insurer,
to the extent required by the policy, and its terms are reflected on the
Mortgage Loan Schedule. No Mortgagor has been released, in whole or in part,
except in connection with an assumption agreement approved by the issuer of
any related PMI Policy and the title insurer, to the extent required by the
policy, and which assumption agreement is part of the Mortgage Loan File
delivered to the Purchaser and the terms of which are reflected in the
Mortgage Loan Schedule;

                  (e) No Defenses. The Mortgage Loan is not subject to any
right of rescission, set-off, counterclaim or defense, including without
limitation the defense of usury, nor will the operation of any of the terms of
the Mortgage Note or the Mortgage, or the exercise of any right thereunder,
render either the Mortgage Note or the Mortgage unenforceable, in whole or in
part, or subject to any right of rescission, set-off, counterclaim or defense,
including without limitation the defense of usury, and no such right of
rescission, set-off, counterclaim or defense has been asserted with respect
thereto;

                                     II-1
<PAGE>

                  (f) Hazard Insurance. Pursuant to the terms of the Mortgage,
all buildings or other improvements upon the Mortgaged Property are insured by
a generally acceptable insurer against loss by fire, hazards of extended
coverage and such other hazards as are customary in the area where the
Mortgaged Property is located. If upon origination of the Mortgage Loan, the
Mortgaged Property was in an area identified in the Federal Register by the
Federal Emergency Management Agency as having special flood hazards a
life-of-loan flood insurance policy meeting the requirements of the current
guidelines of the Federal Flood Insurance Administration is in effect. The
Mortgage obligates the Mortgagor thereunder to maintain the hazard insurance
policy at the Mortgagor's cost and expense, and on the Mortgagor's failure to
do so, authorizes the holder of the Mortgage to obtain and maintain such
insurance at such Mortgagor's cost and expense, and to seek reimbursement
therefor from the Mortgagor. Where required by state law or regulation, the
Mortgagor has been given an opportunity to choose the carrier of the required
hazard insurance, provided the policy is not a "master" or "blanket" hazard
insurance policy covering the common facilities of a planned unit development.
The hazard insurance policy is the valid and binding obligation of the
insurer, is in full force and effect, and will be in full force and effect and
inure to the benefit of the Purchaser upon the consummation of the
transactions contemplated by this Agreement. The Seller has not engaged in,
and has no knowledge of the Mortgagor's or any subservicer's having engaged
in, any act or omission which would impair the coverage of any such policy,
the benefits of the endorsement provided for herein, or the validity and
binding effect of either, including, without limitation, no unlawful fee,
commission, kickback or other unlawful compensation or value of any kind has
been or will be received, retained or realized by any attorney, firm or other
person or entity, and no such unlawful items have been received, retained or
realized by the Seller;

                  (g) Compliance with Applicable Laws. Each Mortgage Loan at
the time it was made complied in all material respects with applicable local,
state, and federal laws, including, but not limited to all applicable
predatory and abusive lending laws and any and all requirements of any
federal, state or local law (including, without limitation, usury,
truth-in-lending, real estate settlement procedures, consumer credit
protection, equal credit opportunity, disclosure laws, all applicable
predatory and abusive lending laws or unfair and deceptive practices laws)
applicable to the Mortgage Loan have been complied with, and the Seller shall
maintain in its possession, available for the Purchaser's inspection, and
shall deliver to the Purchaser, evidence of compliance with all such
requirements;

                  (h) No Satisfaction of Mortgage. The Mortgage has not been
satisfied, canceled, subordinated or rescinded, in whole or in part, and the
Mortgaged Property has not been released from the lien of the Mortgage, in
whole or in part, nor has any instrument been executed that would effect any
such release, cancellation, subordination or rescission;

                  (i) Location and Type of Mortgaged Property. The Mortgaged
Property is located in the state identified in the Mortgage Loan Schedule and
consists of a single parcel of real property with a detached single family
residence erected thereon, or a two- to four-family dwelling, or an individual
condominium unit in a low-rise condominium project, or an individual unit in a
planned unit development, provided, however, that no residence or dwelling is
a mobile home or a manufactured dwelling. No portion of the Mortgaged Property
is used for commercial purposes;

                                     II-2
<PAGE>

                  (j) Valid First Lien. The Mortgage is a valid, subsisting
enforceable and perfected first lien on the Mortgaged Property, including all
improvements. The lien of the Mortgage is subject only to:

                  (i) the lien of current real property taxes and assessments
         not yet due and payable;

                  (ii) covenants, conditions and restrictions, rights of way,
         easements and other matters of the public record as of the date of
         recording acceptable to mortgage lending institutions generally and
         specifically referred to in the lender's title insurance policy
         delivered to the originator of the Mortgage Loan; and

                  (iii) other matters to which like properties are commonly
         subject which do not materially interfere with the benefits of the
         security intended to be provided by the Mortgage or the use,
         enjoyment, value or marketability of the related Mortgaged Property;

Any security agreement, chattel mortgage or equivalent document related to and
delivered in connection with the Mortgage Loan establishes and creates a
valid, subsisting and enforceable first lien and first priority security
interest on the property described therein and the Seller has full right to
sell and assign the same to the Purchaser;

                  (k) Validity of Mortgage Documents. The Mortgage Note and
the Mortgage are genuine, and each is the legal, valid and binding obligation
of the maker thereof enforceable in accordance with its terms, except as the
enforceability thereof may be limited by bankruptcy, insolvency, or
reorganization or other laws relating to the rights of creditors. All parties
to the Mortgage Note and the Mortgage had legal capacity to enter into the
Mortgage Loan and to execute and deliver the Mortgage Note and the Mortgage,
and the Mortgage Note and the Mortgage have been duly and properly executed by
such parties. To the best of the Seller's knowledge, no fraud was committed in
connection with the origination of the Mortgage Loan and the Seller is not
aware of any fact that would reasonably lead the Seller to believe that any
Mortgagor committed fraud in connection with the origination of any Mortgage
Loan;

                  (l) Full Disbursement of Proceeds. The Mortgage Loan has
been closed and the proceeds of the Mortgage Loan have been fully disbursed
and there is no requirement for future advances thereunder, and any and all
requirements as to completion of any on-site or off-site improvement and as to
disbursements of any escrow funds therefor have been complied with. All costs,
fees and expenses incurred in making or closing the Mortgage Loan and the
recording of the Mortgage were paid;

                  (m) Ownership. The Seller is the sole owner of record and
holder of the Mortgage Loan (other than any servicing rights with respect to
the Mortgage Loans, which are held by _____________________). The Mortgage
Loan (other than any servicing rights with respect to the Mortgage Loans,
which are held by _____________________) and the related Mortgage Note and the
Mortgage are not assigned or pledged, and the Seller has good and marketable
title thereto, and has full right to transfer and sell the Mortgage Loan
(other than any servicing rights with respect to the Mortgage Loans, which are
held by

                                     II-3
<PAGE>

_____________________) therein to the Purchaser free and clear of any
encumbrance, equity, participation interest, lien, pledge, charge, claim or
security interest, and has full right and authority subject to no interest or
participation of, or agreement with, any other party, to sell and assign each
Mortgage Loan (other than any servicing rights with respect to the Mortgage
Loans, which are held by _____________________) pursuant to this Agreement;

                  (n) Doing Business. To the best of the Seller's knowledge,
all parties which have had any interest in the Mortgage Loan, whether as
mortgagee, assignee, pledgee or otherwise, are (or, during the period in which
they held and disposed of such interest, were) (1) in compliance with any and
all applicable licensing requirements of the laws of the state wherein the
Mortgaged Property is located, and (2) organized under the laws of such state,
or (3) qualified to do business in such state, or (4) federal savings and loan
associations or national banks having principal offices in such state, or (5)
not doing business in such state;

                  (o) LTV. The Mortgage Loan has an LTV equal to or less than
the amount set forth on the Mortgage Loan Schedule;

                  (p) Title Insurance. The Mortgage Loan is covered by an ALTA
lender's title insurance policy or other generally acceptable form of policy,
issued by a generally acceptable title insurer and qualified to do business in
the jurisdiction where the Mortgaged Property is located, insuring the Seller,
its successors and assigns, as to the first priority lien of the Mortgage in
the original principal amount of the Mortgage Loan subject only to the
exceptions contained in clauses (1), (2) and (3) of paragraph (j) of these
representations and warranties. Additionally, such lender's title insurance
policy affirmatively insures ingress and egress, and against encroachments by
or upon the Mortgaged Property or any interest therein. The Seller is the sole
insured of such lender's title insurance policy, and such lender's title
insurance policy is in full force and effect and will be in force and effect
upon the consummation of the transactions contemplated by this Agreement. No
claims have been made under such lender's title insurance policy, and no prior
holder of the Mortgage, including the Seller, has done, by act or omission,
anything which would impair the coverage of such lender's title insurance
policy;

                  (q) No Defaults. There is no default, breach, violation or
event of acceleration existing under the Mortgage or the Mortgage Note and no
event which, with the passage of time or with notice and the expiration of any
grace or cure period, would constitute a default, breach, violation or event
of acceleration, the Seller has not waived any default, breach, violation or
event of acceleration;

                  (r) No Mechanics' Liens. To the best of the Seller's
knowledge, there are no mechanics' or similar liens or claims which have been
filed for work, labor or material (and no rights are outstanding that under
the law could give rise to such liens) affecting the related Mortgaged
Property which are or may be liens prior to, or equal or coordinate with, the
lien of the related Mortgage;

                  (s) Location of Improvements; No Encroachments. To the best
of the Seller's knowledge, all improvements which were considered in
determining the Appraised Value of the Mortgaged Property lay wholly within
the boundaries and building restriction lines of the Mortgaged Property and no
improvements on adjoining properties encroach upon the Mortgaged

                                     II-4
<PAGE>

Property (except those exceptions contained in clauses (1), (2) and (3) of
paragraph (j). To the best of the Seller's knowledge, no improvement located
on or being part of the Mortgaged Property is in violation of any applicable
zoning law or regulation;

                  (t) Origination: Payment Terms. At the time the Mortgage
Loan was originated, the originator was a mortgagee approved by the Secretary
of Housing and Urban Development pursuant to Sections 203 and 211 of the
National Housing Act or a savings and loan association, a savings bank, a
commercial bank or similar banking institution which is supervised and
examined by a Federal or State authority. The Mortgage Interest Rate is the
rate adjusted on each Interest Rate Adjustment Date to equal the Index plus
the Gross Margin, rounded up or down to the nearest [0.125]%, subject to the
Periodic Rate Cap and the Lifetime Rate Cap. The Mortgage Note is payable in
substantially equal monthly installments of principal and interest, with
interest calculated and payable in arrears, sufficient to amortize the
Mortgage Loan fully by the stated maturity date, over an original term of not
more than thirty years from commencement of amortization (except with respect
to [__]% of the Mortgage Loans, which provide for payment of interest at the
related mortgage rate, but no payment of principal, for the first five years
following origination of such Mortgage Loans). No Mortgage Loan provides for
negative amortization. No Mortgage Loan is a Convertible Mortgage Loan.

                  (u) Customary Provisions. The Mortgage and related Mortgage
Note contain customary and enforceable provisions such as to render the rights
and remedies of the holder thereof adequate for the realization against the
Mortgaged Property of the benefits of the security provided thereby,
including, (i) in the case of a Mortgage designated as a deed of trust, by
trustee's sale, and (ii) otherwise by judicial foreclosure. There is no
homestead or other exemption available to the Mortgagor which would interfere
with the right to sell the Mortgaged Property at a trustee's sale or the right
