      This Pooling and Servicing Agreement is dated and effective as of March
1, 2006, among STANWICH ASSET ACCEPTANCE COMPANY, L.L.C., a Delaware limited
liability company, as Depositor, OPTION ONE MORTGAGE CORPORATION, a California
corporation, as Servicer, and WELLS FARGO BANK, N.A., a national banking
association, as Trustee.

                             PRELIMINARY STATEMENT:

      The Depositor intends to sell pass-through certificates to be issued
hereunder in multiple classes, which in the aggregate will evidence the entire
beneficial ownership interest in each REMIC (as defined herein) created
hereunder. The Trust Fund (as defined herein) will consist of a segregated pool
of assets comprised of the Mortgage Loans and certain other related assets
subject to this Agreement.

                                     REMIC I

      As provided herein, the Trustee will elect to treat the segregated pool of
assets consisting of the Mortgage Loans and certain other related assets (other
than any Servicer Prepayment Charge Payment Amounts, the Net WAC Rate Carryover
Reserve Account and the Cap Contracts) subject to this Agreement as a REMIC for
federal income tax purposes, and such segregated pool of assets will be
designated as "REMIC I." The Class R-I Interest will be the sole class of
"residual interests" in REMIC I for purposes of the REMIC Provisions (as defined
herein). The following table irrevocably sets forth the designation, the REMIC I
Remittance Rate, the initial Uncertificated Balance and, for purposes of
satisfying Treasury regulation Section 1.860G-1(a)(4)(iii), the "latest possible
maturity date" for each of the REMIC I Regular Interests (as defined herein).
None of the REMIC I Regular Interests will be certificated.

____________________
(1)   For purposes of Section 1.860G-1(a)(4)(iii) of the Treasury regulations,
      the Distribution Date immediately following the maturity date for the
      Mortgage Loans with the latest maturity date has been designated as the
      "latest possible maturity date" for each Class of Certificates.

(2)   Calculated in accordance with the definition of "Pass-Through Rate"
      herein.

(3)   The Class CE Certificates will be comprised of two REMIC II Regular
      Interests, a principal only regular interest designated REMIC II Regular
      Interest CE-PO and an interest only regular interest designated REMIC II
      Regular Interest CE-IO, each of which will be entitled to distributions as
      set forth herein.

(4)   The Class CE Certificates will accrue interest at its variable
      Pass-Through Rate on the Notional Amount of the Class CE-IO outstanding
      from time to time which notional amount shall equal the aggregate
      Uncertificated Balance of the REMIC I Regular Interests. The Class CE
      Certificates will not accrue interest on its Certificate Principal
      Balance.

(5)   The Class P Certificates will not accrue interest.

      As of the Cut-off Date, the Mortgage Loans had an aggregate Stated
Principal Balance equal to $1,015,025,383.08.

      In consideration of the mutual agreements herein contained, the Depositor,
the Servicer and the Trustee agree as follows:

                                        3

                                    ARTICLE I

specified, all calculations described herein shall be made on the basis of a
360-day year consisting of twelve 30-day months.

      SECTION 1.02 Allocation of Certain Interest Shortfalls. For purposes of
calculating the amount of Accrued Certificate Interest and the amount of the

on, and to the extent of, one month's interest at the then applicable
Pass-Through Rate on the Notional Amount of the Class CE Certificates and,
thereafter, among the Class A Certificates and the Mezzanine Certificates on a
pro rata basis based on, and to the extent of, one month's interest at the then
applicable respective Pass-Through Rate on the respective Certificate Principal
Balance of each such Certificate and (2) the aggregate amount of any Realized
Losses incurred for any Distribution Date shall be allocated to the Class CE
Certificates based on, and to the extent of, one month's interest at the then
applicable Pass-Through Rate on the Notional Amount of the Class CE
Certificates.

                                   ARTICLE II

                          CONVEYANCE OF MORTGAGE LOANS;
                        ORIGINAL ISSUANCE OF CERTIFICATES

      SECTION 2.01 Conveyance of the Mortgage Loans. On the Closing Date, the
Depositor will transfer, assign, set over and otherwise convey to the Trustee
without recourse, for the

                                        4

benefit of the Certificateholders, all the right, title and interest of the
Depositor, including any security interest therein for the benefit of the
Depositor, in and to the Mortgage Loans identified on the Mortgage Loan
Schedule, the rights of the Depositor under the Mortgage Loan Purchase
Agreement, and all other assets included or to be included in REMIC I. Such
assignment includes all interest and principal received by the Depositor or the
Servicer on or with respect to the Mortgage Loans (other than payments of
principal and interest due on such Mortgage Loans on or before the Cut-off
Date). The Depositor herewith delivers to the Trustee an executed copy of the
Mortgage Loan Purchase Agreement.

      In connection with such transfer and assignment, the Depositor shall
deliver to and deposit with the Trustee the following documents or instruments
with respect to each Mortgage Loan so transferred and assigned (in each case, a
"Mortgage File"):

            (i)     the original Mortgage Note, endorsed in blank or in the
      following form "Pay to the order of Wells Fargo Bank, N.A., as Trustee
      under the applicable agreement, without recourse," with all prior and
      intervening endorsements showing a complete chain of endorsement from the
      originator to the Person so endorsing to the Trustee;

            (ii)    the original Mortgage with evidence of recording thereon,
      and the original recorded power of attorney, if the Mortgage was executed
      pursuant to a power of attorney, with evidence of recording thereon;

            (iii)   an original Assignment in blank;

            (iv)    the original recorded Assignment or Assignments showing a
      complete chain of assignment from the originator to the Person assigning
      the Mortgage to the Trustee as contemplated by the immediately preceding
      clause (iii);

            (v)     the original or copies of each assumption, modification,
      consolidation or extension agreements, if any; and

            (vi)    the original or a copy of the original lender's title
      insurance policy or, if the original title policy has not been issued, the
      irrevocable commitment to issue the same.

      With respect to a maximum of approximately 2.0% of the Original Mortgage
Loans by outstanding Stated Principal Balance of the Original Mortgage Loans as
of the Cut-off Date, if any original Mortgage Note referred to in Section
2.01(i) above cannot be located, the obligations of the Depositor to deliver
such documents shall be deemed to be satisfied upon delivery to the Trustee of a
photocopy of such Mortgage Note, if available, with a lost note affidavit
substantially in the form of Exhibit H attached hereto. If any of the original
Mortgage Notes for which a lost note affidavit was delivered to the Trustee is
subsequently located, such original Mortgage Note shall be delivered to the
Trustee within three Business Days.

      If any of the documents referred to in Sections 2.01(ii), (iii) or (iv)
above has, as of the Closing Date, been submitted for recording but either (x)
has not been returned from the applicable public recording office or (y) has
been lost or such public recording office has

                                        5

retained the original of such document, the obligations of the Depositor to
deliver such documents shall be deemed to be satisfied upon (1) delivery to the
Trustee of a copy of each such document certified by the Originator in the case
of (x) above or the applicable public recording office in the case of (y) above
to be a true and complete copy of the original that was submitted for recording
and (2) if such copy is certified by the Originator, delivery to the Trustee,
promptly upon receipt thereof of either the original or a copy of such document
certified by the applicable public recording office to be a true and complete
copy of the original. Notice shall be provided to the Trustee and the Rating
Agencies by the Depositor if delivery pursuant to clause (2) above will be made
more than 180 days after the Closing Date. If the original lender's title
insurance policy was not delivered pursuant to Section 2.01(vi) above, the
Depositor shall deliver or cause to be delivered to the Trustee, promptly after
receipt thereof, the original lender's title insurance policy. The Depositor
shall deliver or cause to be delivered to the Trustee promptly upon receipt
thereof any other original documents constituting a part of a Mortgage File
received with respect to any Mortgage Loan, including, but not limited to, any
original documents evidencing an assumption or modification of any Mortgage
Loan.

      The Trustee shall enforce the obligations of the Seller under the Mortgage
Loan Purchase Agreement to promptly (within sixty Business Days following the
later of the Closing Date and the date of receipt by the Trustee of the
recording information for a Mortgage, but in no event later than ninety days
following the Closing Date) submit or cause to be submitted for recording, at
the expense of the Responsible Party and at no expense to the Trust Fund, the
Trustee or the Depositor, in the appropriate public office for real property
records, each Assignment referred to in Sections 2.01(iii) and (iv) above and
the Depositor shall execute each original Assignment or cause each original
Assignment to be executed in the following form: "Wells Fargo Bank, N.A., as
Trustee under the applicable agreement." In the event that any such Assignment
is lost or returned unrecorded because of a defect therein, the Seller shall
promptly prepare or cause to be prepared (at the expense of the Responsible
Party) a substitute Assignment or cure or cause to be cured such defect, as the
case may be, and thereafter cause each such Assignment to be duly recorded. If
the Responsible Party is unable to pay the cost of recording the Assignments,
such expense will be paid by the Trustee and shall be reimbursable to the
Trustee as an Extraordinary Trust Fund Expense. Notwithstanding the foregoing,
the Trustee shall not be responsible for determining whether any Assignment
delivered by the Depositor hereunder is in recordable form.

      Notwithstanding the foregoing, however, for administrative convenience and
facilitation of servicing and to reduce closing costs, the Assignments shall not
be required to be submitted for recording (except with respect to any Mortgage
Loan located in Maryland) unless the Trustee or the Depositor receives written
notice that failure to record would result in a withdrawal or a downgrading by
any Rating Agency of the rating on any Class of Certificates; provided, however,
the Trustee shall enforce the obligations of the Seller under the Mortgage Loan
Purchase Agreement to submit or cause to be submitted each Assignment for
recording in the manner described above, at no expense to the Trust Fund or the
Trustee, upon the earliest to occur of: (i) reasonable direction by Holders of
Certificates entitled to at least 25% of the Voting Rights, (ii) the occurrence
of a Servicer Event of Default, (iii) the occurrence of a bankruptcy, insolvency
or foreclosure relating to the Servicer, (iv) the occurrence of a servicing
transfer as described in Section 7.02 hereof, (v) with respect to any one
Assignment, the occurrence of a

                                        6

bankruptcy, insolvency or foreclosure relating to the Mortgagor under the
related Mortgage and (vi) any Mortgage Loan that is 90 days or more delinquent.
Upon receipt of written notice by the Trustee from the Servicer that recording
of the Assignments is required pursuant to one or more of the conditions set
forth in the preceding sentence, the Depositor shall be required to deliver such
Assignments or shall cause such Assignments to be delivered within 30 days
following receipt of such notice.

      All original documents relating to the Mortgage Loans that are not
delivered to the Trustee are and shall be held by or on behalf of the Seller,
the Depositor or the Servicer, as the case may be, in trust for the benefit of
the Trustee on behalf of the Certificateholders. In the event that any such
original document is required pursuant to the terms of this Section 2.01 to be a
part of a Mortgage File, such document shall be delivered promptly to the
Trustee. Any such original document delivered to or held by the Depositor that
is not required pursuant to the terms of this Section to be a part of a Mortgage
File, shall be delivered promptly to the Servicer.

      The parties hereto understand and agree that it is not intended that any
Mortgage Loans be included in the Trust that are (a) "high cost" loans under the
Home Ownership and Equity Protection Act of 1994 or (b) "high cost,"
"threshold," "covered" or "predatory" loans under any other applicable federal,
state or local law (including without limitation any regulation or ordinance)
(or a similarly classified loan using different terminology under a law imposing
heightened regulatory scrutiny or additional legal liability for residential
mortgage loans having high interest rates, points and/or fees).

      SECTION 2.02 Acceptance of REMIC I by Trustee. The Trustee acknowledges
receipt subject to the provisions of Section 2.01 above and subject to any
exceptions noted on the exception report described in the next paragraph below,
of the documents referred to in Section 2.01 (other than such documents
described in Section 2.01(v)) and all other assets included in the definition of
"REMIC I" under clauses (i), (iii), (iv) and (v) (to the extent of amounts
attributable thereto deposited into the Certificate Account) and declares that
it holds and will hold such documents and the other documents delivered to it
constituting a Mortgage File, and that it holds or will hold all such assets and
such other assets included in the definition of "REMIC I" in trust for the
exclusive use and benefit of all present and future Certificateholders.

      The Trustee agrees, for the benefit of the Certificateholders, to review
each Mortgage File on or before the Closing Date, and to certify in
substantially the form attached hereto as Exhibit C-1 that, as to each Mortgage
Loan listed in the Mortgage Loan Schedule (other than any Mortgage Loan paid in
full or any Mortgage Loan specifically identified in the exception report
annexed thereto as not being covered by such certification), (i) all documents
constituting part of such Mortgage File (other than such documents described in
Section 2.01(v)) required to be delivered to it pursuant to this Agreement are
in its possession, (ii) such documents have been reviewed by it and appear
regular on their face and relate to such Mortgage Loan and (iii) based on its
examination and only as to the foregoing, the information set forth in the
Mortgage Loan Schedule that corresponds to items (i), (iii), (xii), (xiii) and
(xvi) of the definition of "Mortgage Loan Schedule" accurately reflects
information set forth in the Mortgage File. It is herein acknowledged that, in
conducting such review, the Trustee was under no duty or obligation (i) to
inspect, review or examine any such documents, instruments, certificates or
other papers to

                                        7

determine whether they are genuine, enforceable, valid, legally binding,
effective or appropriate for the represented purpose or whether they have
actually been recorded or are in recordable form or that they are other than
what they purport to be on their face, (ii) to determine whether any Mortgage
File should include any of the documents specified in clause (v) of Section 2.01
or (iii) to determine the perfection or priority of any security interest in any
such documents or instruments. Notwithstanding the foregoing, in conducting the
review described in this Section 2.02, the Trustee shall not be responsible for
determining (i) if an Assignment is sufficient under the laws of the
jurisdiction wherein the related Mortgaged Property is located to reflect of
record the sale of the Mortgage or (ii) if a Mortgage creates a first or second
lien on, or first or second priority security interest in, a Mortgaged Property.

      Prior to the first anniversary date of this Agreement, the Trustee shall
deliver to the Depositor, the Trustee and the Servicer a final certification in
the form annexed hereto as Exhibit C-2 evidencing the completeness of the
Mortgage Files, with any applicable exceptions noted thereon, and the Servicer
shall forward a copy thereof to any Sub-Servicer.

      If in the process of reviewing the Mortgage Files and making or preparing,
as the case may be, the certifications referred to above, the Trustee, finds any
document or documents constituting a part of a Mortgage File to be missing or
defective in any material respect, at the conclusion of its review the Trustee
shall so notify the Depositor and the Servicer. In addition, upon the discovery
by the Depositor, the Servicer or the Trustee of a breach of any of the
representations and warranties made by either the Responsible Party or the
Seller in the related Mortgage Loan Purchase Agreement in respect of any
Mortgage Loan which materially adversely affects such Mortgage Loan or the
interests of the Certificateholders in such Mortgage Loan, the party discovering
such breach shall give prompt written notice to the other parties.

      The Trustee shall, at the written request and expense of any
Certificateholder, provide a written report to the Trustee for forwarding to
such Certificateholder of all Mortgage Files released to the Servicer for
servicing purposes.

      The Depositor and the Trustee intend that the assignment and transfer
herein contemplated is absolute and constitutes a sale of the Mortgage Loans,
the related Mortgage Notes and the related documents, conveying good title
thereto free and clear of any liens and encumbrances, from the Depositor to the
Trustee in trust for the benefit of the Certificateholders and that such
property not be part of the Depositor's estate or property of the Depositor in
the event of any insolvency by the Depositor. In the event that such conveyance
is deemed to be, or to be made as security for, a loan, the parties intend that
the Depositor shall be deemed to have granted and does hereby grant to the
Trustee a first priority perfected security interest in all of the Depositor's
right, title and interest in and to the Mortgage Loans, the related Mortgage
Notes and the related documents, and that this Agreement shall constitute a
security agreement under applicable law.

      SECTION 2.03 Repurchase or Substitution of Mortgage Loans by the
Responsible Party and the Seller. (a) Upon discovery or receipt of notice of any
materially defective document in, or that a document is missing from, a Mortgage
File or of the breach by the Responsible Party or the Seller of any
representation, warranty or covenant under the Mortgage Loan Purchase

                                        8

Agreement in respect of any Mortgage Loan that materially adversely affects the
value of such Mortgage Loan or the interest therein of the Certificateholders,
the Trustee shall promptly notify the Seller, the Responsible Party and the
Servicer of such defect, missing document or breach and request that the
Responsible Party or the Seller, as applicable, deliver such missing document or
cure such defect or breach within 60 days from the date the Responsible Party or
the Seller, as applicable, was notified of such missing document, defect or
breach, and if the Responsible Party or the Seller, as applicable, does not
deliver such missing document or cure such defect or breach in all material
respects during such period, the Trustee shall enforce the obligations of the
Responsible Party or the Seller, as applicable, under the Mortgage Loan Purchase
Agreement to repurchase such Mortgage Loan from REMIC I at the Purchase Price
within 90 days after the date on which the Responsible Party or the Seller, as
applicable, was notified (subject to Section 2.03(c)) of such missing document,
defect or breach, if and to the extent that the Responsible Party or the Seller,
as applicable, is obligated to do so under the Mortgage Loan Purchase Agreement.
The Purchase Price for the repurchased Mortgage Loan shall be remitted to the
Servicer for deposit in the Custodial Account and the Trustee, upon receipt of
written certification from the Servicer of such deposit, shall release to the
Responsible Party or the Seller, as applicable, the related Mortgage File and
the Trustee shall execute and deliver such instruments of transfer or
assignment, in each case without recourse, as the Responsible Party or the
Seller, as applicable, shall furnish to it and as shall be necessary to vest in
the Responsible Party or the Seller, as applicable, any Mortgage Loan released
pursuant hereto. The Trustee shall not have any further responsibility with
regard to such Mortgage File. In lieu of repurchasing any such Mortgage Loan as
provided above, if so provided in the Mortgage Loan Purchase Agreement, the
Responsible Party or the Seller, as applicable, may cause such Mortgage Loan to
be removed from REMIC I (in which case it shall become a Deleted Mortgage Loan)
and substitute one or more Qualified Substitute Mortgage Loans in the manner and
subject to the limitations set forth in Section 2.03(b); provided, however, the
Responsible Party may not substitute a Qualified Substitute Mortgage Loan for
any Deleted Mortgage Loan that violates any predatory or abusive lending law. It
is understood and agreed that the obligation of the Responsible Party or the
Seller, as applicable, to cure or to repurchase (or to substitute for) any
Mortgage Loan as to which a document is missing, a material defect in a
constituent document exists or as to which such a breach has occurred and is
continuing shall constitute the sole remedy respecting such omission, defect or
breach available to the Trustee and the Certificateholders.

      (b)   Any substitution of Qualified Substitute Mortgage Loans for Deleted
Mortgage Loans made pursuant to Section 2.03(a) must be effected prior to the
date which is two years after the Startup Day for REMIC I.

      As to any Deleted Mortgage Loan for which the Responsible Party or the
Seller, as applicable, substitutes a Qualified Substitute Mortgage Loan or
Loans, such substitution shall be effected by the Responsible Party or the
Seller, as applicable, delivering to the Trustee, for such Qualified Substitute
Mortgage Loan or Loans, the Mortgage Note, the Mortgage, the Assignment to the
Trustee, and such other documents and agreements, with all necessary
endorsements thereon, as are required by Section 2.01, together with an
Officers' Certificate providing that each such Qualified Substitute Mortgage
Loan satisfies the definition thereof and specifying the Substitution Shortfall
Amount (as described below), if any, in connection with such substitution.

                                        9

The Trustee shall acknowledge receipt for such Qualified Substitute Mortgage
Loan or Loans and, within ten Business Days thereafter, shall review such
documents as specified in Section 2.02 and deliver to the Depositor and the
Servicer, with respect to such Qualified Substitute Mortgage Loan or Loans, a
certification substantially in the form attached hereto as Exhibit C-1, with any
applicable exceptions noted thereon. Within one year of the date of
substitution, the Trustee shall deliver to the Depositor and the Servicer a
certification substantially in the form of Exhibit C-2 with respect to such
Qualified Substitute Mortgage Loan or Loans, with any applicable exceptions
noted thereon. Monthly Payments due with respect to Qualified Substitute
Mortgage Loans in the month of substitution are not part of REMIC I and will be
retained by the Responsible Party or the Seller, as applicable. For the month of
substitution, distributions to Certificateholders will reflect the Monthly
Payment due on such Deleted Mortgage Loan on or before the Due Date in the month
of substitution, and the Responsible Party or the Seller, as applicable, shall
thereafter be entitled to retain all amounts subsequently received in respect of
such Deleted Mortgage Loan. The Depositor shall give or cause to be given
written notice to the Certificateholders that such substitution has taken place,
shall amend the Mortgage Loan Schedule to reflect the removal of such Deleted
Mortgage Loan from the terms of this Agreement and the substitution of the
Qualified Substitute Mortgage Loan or Loans and shall deliver a copy of such
amended Mortgage Loan Schedule to the Trustee. Upon such substitution, such
Qualified Substitute Mortgage Loan or Loans shall constitute part of the
Mortgage Pool and shall be subject in all respects to the terms of this
Agreement and the Mortgage Loan Purchase Agreement, including, all applicable
representations and warranties thereof included in the Mortgage Loan Purchase
Agreement.

      For any month in which the Responsible Party or the Seller, as applicable,
substitutes one or more Qualified Substitute Mortgage Loans for one or more
Deleted Mortgage Loans, the Servicer will determine the amount (the
"Substitution Shortfall Amount"), if any, by which the aggregate Purchase Price
of all such Deleted Mortgage Loans exceeds the aggregate of, as to each such
Qualified Substitute Mortgage Loan, the Stated Principal Balance thereof as of
the date of substitution, together with one month's interest on such Stated
Principal Balance at the applicable Expense Adjusted Mortgage Rate, plus all
outstanding Advances and Servicing Advances (including Nonrecoverable Advances
and Nonrecoverable Servicing Advances) related thereto. On the date of such
substitution, the Responsible Party or the Seller, as applicable, will deliver
or cause to be delivered to the Servicer for deposit in the Custodial Account an
amount equal to the Substitution Shortfall Amount, if any, and upon receipt of
the related Qualified Substitute Mortgage Loan or Loans and certification by the
Servicer of such deposit, release to the Responsible Party or the Seller, as
applicable, the related Mortgage File or Files and the Trustee shall execute and
deliver such instruments of transfer or assignment, in each case without
recourse, the Responsible Party or the Seller, as applicable, shall deliver to
it and as shall be necessary to vest therein any Deleted Mortgage Loan released
pursuant hereto.

      In addition, the Responsible Party or the Seller, as applicable, shall
obtain at its own expense and deliver to the Trustee an Opinion of Counsel to
the effect that such substitution will not cause (a) any federal tax to be
imposed on any Trust REMIC, including without limitation, any federal tax
imposed on "prohibited transactions" under Section 860F(a)(1) of the Code or on
"contributions after the startup date" under Section 860G(d)(1) of the Code, or
(b) any Trust REMIC to fail to qualify as a REMIC at any time that any
Certificate is outstanding.

                                       10

      (c)   Upon discovery by the Depositor, the Servicer or the Trustee that
any Mortgage Loan does not constitute a "qualified mortgage" within the meaning
of Section 860G(a)(3) of the Code, the party discovering such fact shall within
two Business Days give written notice thereof to the other parties. In
connection therewith, the Responsible Party shall repurchase or, subject to the
limitations set forth in Section 2.03(b), substitute one or more Qualified
Substitute Mortgage Loans for the affected Mortgage Loan within 90 days of the
earlier of discovery or receipt of such notice with respect to such affected
Mortgage Loan. Such repurchase or substitution shall be made by (i) the
Responsible Party or the Seller, as the case may be, if the affected Mortgage
Loan's status as a non-qualified mortgage is or results from a breach of any
representation, warranty or covenant made by the Responsible Party or the
Seller, as the case may be, under the Mortgage Loan Purchase Agreement, or (ii)
the Depositor, if the affected Mortgage Loan's status as a non-qualified
mortgage is a breach of no representation or warranty. Any such repurchase or
substitution shall be made in the same manner as set forth in Section 2.03(a).
The Trustee shall reconvey to the Responsible Party the Mortgage Loan to be
released pursuant hereto in the same manner, and on the same terms and
conditions, as it would a Mortgage Loan repurchased for breach of a
representation or warranty.

      SECTION 2.04  [Reserved].

      SECTION 2.05 Representations, Warranties and Covenants of the Servicer.
The Servicer hereby represents, warrants and covenants to the Trustee, for the
benefit of the Certificateholders and to the Depositor that as of the Closing
Date or as of such date specifically provided herein:

            (i)     The Servicer is 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 and
      is licensed, qualified and in good standing in the states where the
      Mortgaged Property is located if the laws of such state require licensing
      or qualification in order to conduct business of the type conducted by the
      Servicer or to ensure the enforceability or validity of each Mortgage
      Loan; the Servicer has the 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, subject to applicable bankruptcy,
      insolvency, reorganization, moratorium or other similar laws affecting the
      enforcement of creditors' 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)    The consummation of the transactions contemplated by this
      Agreement are in the ordinary course of business of the Servicer and will
      not result in the breach of any term or provision of the charter or
      by-laws of the Servicer or result in the breach of any term or provision
      of, or conflict with or constitute a default under or result in the
      acceleration of any obligation under, any agreement, indenture or loan or
      credit agreement or other instrument to which the Servicer or its property
      is subject, or result in

                                       11

      the violation of any law, rule, regulation, order, judgment or decree to
      which the Servicer or its property is subject;

            (iii)   The execution and delivery of this Agreement by the Servicer
      and the performance and compliance with its obligations and covenants
      hereunder do not require the consent or approval of any governmental
      authority or, if such consent or approval is required, it has been
      obtained;

            (iv)    This Agreement, and all documents and instruments
      contemplated hereby which are executed and delivered by the Servicer,
      constitute and will constitute valid, legal and binding obligations of the
      Servicer, enforceable in accordance with their respective terms, except as
      the enforcement thereof may be limited by applicable bankruptcy laws and
      general principles of equity;

            (v)     The Servicer is not in violation of, and the execution and
      delivery of this Agreement by the Servicer and its performance and
      compliance with the terms of this Agreement will not constitute a
      violation with respect to, any order or decree of any court or any order
      or regulation of any federal, state, municipal or governmental agency
      having jurisdiction over the Servicer or its assets, which violation will
      likely have consequences that would materially and adversely affect the
      condition (financial or otherwise) or the operation of the Servicer or its
      assets or will likely have consequences that would materially and
      adversely affect the performance of its obligations and duties hereunder
      or result in the creation or imposition of any lien, charge or encumbrance
      that would have an adverse effect upon any of its properties pursuant to
      the terms of any mortgage, contract, deed of trust or other instrument, or
      impair the ability of the Trustee to realize on the Mortgage Loans, impair
      the value of the Mortgage Loans, or impair the ability of the Trustee to
      realize the full amount of any insurance benefits accruing pursuant to
      this Agreement;

            (vi)    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;

            (vii)   There is no action, suit, proceeding or investigation
      pending or, to its knowledge, threatened against the Servicer that, either
      individually or in the aggregate, (A) may result in any change in the
      business, operations, financial condition, properties or assets of the
      Servicer that might prohibit or materially and adversely affect the
      performance by such Servicer of its obligations under, or validity or
      enforceability of, this Agreement, or (B) may result in any material
      impairment of the right or ability of the Servicer to carry on its
      business substantially as now conducted, or (C) may result in any material
      liability on the part of the Servicer, or (D) would draw into question the
      validity or enforceability of this Agreement or of any action taken or to
      be taken in connection with the obligations of the Servicer contemplated
      herein, or (E) would otherwise be likely to impair materially the ability
      of the Servicer to perform under the terms of this Agreement;

                                       12

            (viii)  Neither this Agreement nor any information, certificate of
      an officer, statement furnished in writing or report delivered to the
      Trustee by the Servicer in connection with the transactions contemplated
      hereby contains any untrue statement of a material fact or omits a
      material fact necessary to make the information, certificate, statement or
      report not misleading;

            (ix)    The Servicer will not waive any Prepayment Charge unless it
      is waived in accordance with the standard set forth in Section 3.01;

            (x)     The Servicer has accurately and fully reported, and will
      continue to accurately and fully report, in accordance with the Fair
      Credit Reporting Act and its implementing regulations, accurate and
      complete information (e.g., favorable and unfavorable) on its borrower
      credit files to Equifax, Experian and Trans Union Credit Information
      Company (three of the credit repositories), on a monthly basis;

            (xi)    The Servicer is an approved servicer for FHLMC in good
      standing and is a HUD approved mortgagee pursuant to Section 203 of the
      National Housing Act. No event has occurred, including but not limited to
      a change in insurance coverage, which would make the Servicer unable to
      comply with FHLMC or HUD eligibility requirements or which would require
      notification to FHLMC or HUD. The Servicer has the facilities, procedures,
      and experienced personnel necessary for the sound servicing of mortgage
      loans of the same type as the Mortgage Loans. The Servicer is duly
      qualified, licensed, registered and otherwise authorized under all
      applicable federal, state and local laws, and regulations, if applicable,
      meets the minimum capital requirements set forth by HUD, the OTS, the OCC
      or the FDIC, if applicable, and is in good standing to enforce, originate,
      sell mortgage loans to, and service mortgage loans in each jurisdiction
      wherein the Mortgaged Properties are located;

            (xii)   The Servicer acknowledges and agrees that the Servicing Fee,
      represents reasonable compensation for performing such services and that
      the entire Servicing Fee shall be treated by the Servicer, for accounting
      and tax purposes, as compensation for the servicing and administration of
      the Mortgage Loans pursuant to this Agreement; and

            (xiii)  The Servicer has complied with all applicable anti-money
      laundering laws and regulations, including, without limitation, the USA
      PATRIOT Act of 2001.

      It is understood and agreed that the representations, warranties and
covenants set forth in this Section 2.05 shall survive delivery of the Mortgage
Files to the Trustee and shall inure to the benefit of the Trustee, the
Depositor and the Certificateholders. Upon discovery by any of the Depositor,
the Servicer or the Trustee of a breach of any of the foregoing representations,
warranties and covenants which materially and adversely affects the value of any
Mortgage Loan or the interests therein of the Certificateholders, the party
discovering such breach shall give prompt written notice (but in no event later
than two Business Days following such discovery) to the Trustee. Subject to
Section 7.01, unless such breach shall not be susceptible of cure within 90
days, the obligation of the Servicer set forth in this Section 2.05 to cure
breaches shall constitute the sole remedy against the Servicer available to the
Certificateholders, the Depositor

                                       13

and the Trustee on behalf of the Certificateholders respecting a breach of the
representations, warranties and covenants contained in this Section 2.05.
Notwithstanding the foregoing, within 90 days of the earlier of discovery by the
Servicer or receipt of notice by the Servicer of the breach of the
representation or covenant of the Servicer set forth in Section 2.05(ix) above,
which breach materially and adversely affects the interests of the Holders of
the Class P Certificates in any Prepayment Charge, the Servicer shall pay the
amount of such waived Prepayment Charge, for the benefit of the Holders of the
Class P Certificates, by depositing such amount into the Custodial Account.

      SECTION 2.06 Issuance of the REMIC I Regular Interests and the Class R-I
Interest. The Trustee acknowledges the assignment to it of the Mortgage Loans
and the delivery to it of the Mortgage Files, subject to the provisions of
Section 2.01 and Section 2.02, together with the assignment to it of all other
assets included in REMIC I, the receipt of which is hereby acknowledged.
Concurrently with such assignment and delivery and in exchange therefor, the
Trustee, pursuant to the written request of the Depositor executed by an officer
of the Depositor, has executed, authenticated and delivered to or upon the order
of the Depositor, the Class R Certificates (in respect of the Class R-I
Interest) in authorized denominations. The interests evidenced by the Class R-I
Interest, together with the REMIC I Regular Interests, constitute the entire
beneficial ownership interest in REMIC I. The rights of the Class R-I Interest
and REMIC II (as holder of the REMIC I Regular Interest) to receive
distributions from the proceeds of REMIC I in respect of the Class R-I Interest
and the REMIC I Regular Interests, and all ownership interests evidenced or
constituted by the Class R-I Interest and the REMIC I Regular Interests, shall
be as set forth in this Agreement.

      SECTION 2.07 Conveyance of the REMIC I Regular Interests; Acceptance of
REMIC II by the Trustee. The Depositor, concurrently with the execution and
delivery hereof, does hereby transfer, assign, set over and otherwise convey to
the Trustee, without recourse all the right, title and interest of the Depositor
in and to the REMIC I Regular Interests for the benefit of the Class R-II
Interest and REMIC II (as holder of the REMIC I Regular Interests). The Trustee
acknowledges receipt of the REMIC I Regular Interests and declares that it holds
and will hold the same in trust for the exclusive use and benefit of all present
and future holders of the Class R-II Interest and REMIC II (as holder of the
REMIC I Regular Interests). The rights of the holders of the Class R-II Interest
and REMIC II (as holder of the REMIC I Regular Interests) to receive
distributions from the proceeds of REMIC II in respect of the Class R-II
Interest and REMIC II Regular Interests, respectively, and all ownership
interests evidenced or constituted by the Class R-II Interest and the REMIC II
Regular Interests, shall be as set forth in this Agreement.

      SECTION 2.08 Issuance of Class R Certificates. The Trustee acknowledges
the assignment to it of the REMIC Regular Interests and, concurrently therewith
and in exchange therefor, pursuant to the written request of the Depositor
executed by an officer of the Depositor, the Trustee has executed, authenticated
and delivered to or upon the order of the Depositor, the Class R Certificates in
authorized denominations.

                                   ARTICLE III

                                       14

                          ADMINISTRATION AND SERVICING
                              OF THE MORTGAGE LOANS

      SECTION 3.01 Servicer to Act as Servicer. The Servicer shall service and
administer the Mortgage Loans on behalf of the Trust Fund and in the best
interests of and for the benefit of the Certificateholders (as determined by the
Servicer in its reasonable judgment) in accordance with all applicable laws and
the terms of this Agreement and the respective Mortgage Loans and, to the extent
consistent with such terms, in the same manner in which it services and
administers similar mortgage loans for its own portfolio, and in accordance with
customary and usual standards of practice of mortgage lenders and loan servicers
administering similar mortgage loans but without regard to:

            (i)     any relationship that the Servicer, any Sub-Servicer or any
      Affiliate of the Servicer or any Sub-Servicer may have with the related
      Mortgagor;

            (ii)    the ownership or non-ownership of any Certificate by the
      Servicer or any Affiliate of the Servicer;

            (iii)   the Servicer's obligation to make Advances or Servicing
      Advances; or

            (iv)    the Servicer's or any Sub-Servicer's right to receive
      compensation for its services hereunder or with respect to any particular
      transaction.

      To the extent consistent with the foregoing, the Servicer (a) shall seek
the timely and complete recovery of principal and interest on the Mortgage Notes
and (b) shall waive (or permit a Sub-Servicer to waive) a Prepayment Charge only
under the following circumstances: (i) such waiver is standard and customary in
servicing similar Mortgage Loans, relates to a default or a reasonably
foreseeable default and would, in the reasonable judgment of the Servicer,
maximize recovery of total proceeds taking into account the value of such
Prepayment Charge and the related Mortgage Loan or (ii) such Prepayment Charge
is unenforceable in accordance with applicable law or the collection of such
related Prepayment Charge would otherwise violate applicable law. If a
Prepayment Charge is waived as permitted by meeting the standards described in
clause (ii) above, then the Servicer (in its capacity as Originator) shall be
required to pay the amount of such waived Prepayment Charge, for the benefit of
the Holders of the Class P Certificates, by depositing such amount into the
Custodial Account together with and at the time that the amount prepaid on the
related Mortgage Loan is required to be deposited into the Custodial Account.
Notwithstanding any other provisions of this Agreement, any payments made by the
Servicer in respect of any waived Prepayment Charges pursuant to clause (ii)
above shall be deemed to be paid outside of the Trust Fund.

      Subject only to the above-described servicing standards and the terms of
this Agreement and of the respective Mortgage Loans, the Servicer shall have
full power and authority, acting alone or through Sub-Servicers as provided in
Section 3.02, to do or cause to be done any and all things in connection with
such servicing and administration which it may deem necessary or desirable.
Without limiting the generality of the foregoing, the Servicer in its own name
or in the name of a Sub-Servicer is hereby authorized and empowered by the
Trustee when the Servicer

                                       15

believes it appropriate in its best judgment, for the benefit of the
Certificateholders, in accordance with the servicing standards set forth above,
to execute and deliver, on behalf of the Trust Fund, the Certificateholders and
the Trustee or any of them, and upon written notice to the Trustee, 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 the Mortgaged Properties and to institute foreclosure proceedings or
obtain a deed-in-lieu of foreclosure so as to convert the ownership of such
properties, and to hold or cause to be held title to such properties, on behalf
of the Trustee and Certificateholders. The Servicer shall service and administer
the Mortgage Loans in accordance with applicable state and federal law and shall
provide to the Mortgagors any reports required to be provided to them thereby.
The Servicer shall also comply in the performance of this Agreement with all
reasonable rules and requirements of each insurer under any standard hazard
insurance policy. Subject to Section 3.17, the Trustee shall execute, at the
written request of the Servicer, and furnish to the Servicer and any
Sub-Servicer any special or limited powers of attorney and other documents
necessary or appropriate to enable the Servicer or any Sub-Servicer to carry out
their servicing and administrative duties hereunder and the Trustee shall not be
liable for the actions of the Servicer or any Sub-Servicers under such powers of
attorney.

      Subject to Section 3.09 hereof, in accordance with the standards of the
preceding paragraph, the Servicer shall advance or cause to be advanced funds as
necessary for the purpose of effecting the timely payment of taxes and
assessments on the Mortgaged Properties, which advances shall be Servicing
Advances reimbursable in the first instance from related collections from the
Mortgagors pursuant to Section 3.09, and further as provided in Section 3.11.
Any cost incurred by the Servicer or by Sub-Servicers in effecting the timely
payment of taxes and assessments on a Mortgaged Property shall not, for the
purpose of calculating distributions to Certificateholders, be added to the
unpaid principal balance of the related Mortgage Loan, notwithstanding that the
terms of such Mortgage Loan so permit.

      Notwithstanding anything in this Agreement to the contrary, the Servicer
may not make any future advances with respect to a Mortgage Loan (except as
provided in Section 4.03) and the Servicer shall not (i) permit any modification
with respect to any Mortgage Loan that would change the Mortgage Rate, reduce or
increase the principal balance (except for reductions resulting from actual
payments of principal) or change the final maturity date on such Mortgage Loan
(unless, as provided in Section 3.07, the Mortgagor is in default with respect
to the Mortgage Loan or such default is, in the judgment of the Servicer,
reasonably foreseeable) or (ii) permit any modification, waiver or amendment of
any term of any Mortgage Loan that would both (A) effect an exchange or
reissuance of such Mortgage Loan under Section 1001 of the Code (or Treasury
regulations promulgated thereunder) and (B) cause any Trust REMIC to fail to
qualify as a REMIC under the Code or the imposition of any tax on "prohibited
transactions" or "contributions after the startup date" under the REMIC
Provisions.

      The Servicer may delegate its responsibilities under this Agreement;
provided, however, that no such delegation shall release the Servicer from the
responsibilities or liabilities arising under this Agreement.

                                       16

      SECTION 3.02 Sub-Servicing Agreements Between Servicer and Sub-Servicers.
(a)Subject to Section 14.01(d), the Servicer may enter into Sub-Servicing
Agreements with Sub-Servicers for the servicing and administration of the
Mortgage Loans; provided, however, that such agreements would not result in a
withdrawal or a downgrading by any Rating Agency of the rating on any Class of
Certificates. The Trustee is hereby authorized to acknowledge, at the request of
the Servicer, any Sub-Servicing Agreement that, based on an Officers'
Certificate of the Servicer delivered to the Trustee (upon which the Trustee can
conclusively rely), meets the requirements applicable to Sub-Servicing
Agreements set forth in this Agreement and that is otherwise permitted under
this Agreement.

      Each Sub-Servicer shall be (i) authorized to transact business in the
state or states where the related Mortgaged Properties it is to service are
situated, if and to the extent required by applicable law to enable the
Sub-Servicer to perform its obligations hereunder and under the Sub-Servicing
Agreement and (ii) a Freddie Mac or Fannie Mae approved mortgage servicer. Each
Sub-Servicing Agreement must impose on the Sub-Servicer requirements conforming
to the provisions set forth in Section 3.08 and provide for servicing of the
Mortgage Loans consistent with the terms of this Agreement. The Servicer will
examine each Sub-Servicing Agreement and will be familiar with the terms
thereof. The terms of any Sub-Servicing Agreement will not be inconsistent with
any of the provisions of this Agreement. The Servicer and the Sub-Servicers may
enter into and make amendments to the Sub-Servicing Agreements or enter into
different forms of Sub-Servicing Agreements; provided, however, that any such
amendments or different forms shall be consistent with and not violate the
provisions of this Agreement, and that no such amendment or different form shall
be made or entered into which could be reasonably expected to be materially
adverse to the interests of the Certificateholders without the consent of the
Holders of Certificates entitled to at least 66% of the Voting Rights; provided,
further, that the consent of the Holders of Certificates entitled to at least
66% of the Voting Rights shall not be required (i) to cure any ambiguity or
defect in a Sub-Servicing Agreement, (ii) to correct, modify or supplement any
provisions of a Sub-Servicing Agreement, or (iii) to make any other provisions
with respect to matters or questions arising under a Sub-Servicing Agreement,
which, in each case, shall not be inconsistent with the provisions of this
Agreement. Any variation without the consent of the Holders of Certificates
entitled to at least 66% of the Voting Rights from the provisions set forth in
Section 3.08 relating to insurance or priority requirements of Sub-Servicing
Accounts, or credits and charges to the Sub-Servicing Accounts or the timing and
amount of remittances by the Sub-Servicers to the Servicer, are conclusively
deemed to be inconsistent with this Agreement and therefore prohibited. The
Servicer shall deliver to the Trustee, upon its request, copies of all
Sub-Servicing Agreements, and any amendments or modifications thereof, promptly
upon the Servicer's execution and delivery of such instruments.

      (b)   As part of its servicing activities hereunder, the Servicer, for the
benefit of the Trustee and the Certificateholders, shall enforce the obligations
of each Sub-Servicer under the related Sub-Servicing Agreement, including,
without limitation, any obligation of a Sub-Servicer to make advances in respect
of delinquent payments as required by a Sub-Servicing Agreement, or to purchase
a Mortgage Loan on account of missing or defective documentation or on account
of a breach of a representation, warranty or covenant, as described in Section
2.03(a). Such enforcement, including, without limitation, the legal prosecution
of claims, termination of Sub-

                                       17

Servicing Agreements, 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 Servicer, in
its good faith business judgment, would require were it the owner of the related
Mortgage Loans. The Servicer shall pay the costs of enforcing the obligations of
a Sub-Servicer at its own expense, and shall be reimbursed therefor only (i)
from a general recovery resulting from such enforcement, to the extent, if any,
that such recovery exceeds all amounts due in respect of the related Mortgage
Loans, or (ii) from a specific recovery of costs, expenses or attorneys' fees
against the party against whom such enforcement is directed.

      SECTION 3.03 Successor Sub-Servicers. 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. 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 which qualifies under Section 3.02.

      Any Sub-Servicing Agreement shall include the provision that such
agreement may be immediately terminated by the Trustee (if the Trustee is acting
as Servicer) without fee, in accordance with the terms of this Agreement, in the
event that the Servicer (or the Trustee, if it is then acting as Servicer)
shall, for any reason, no longer be the Servicer (including termination due to a
Servicer Event of Default).

      SECTION 3.04 Liability of the Servicer. Notwithstanding any Sub-Servicing
Agreement or the provisions of this Agreement relating to agreements or
arrangements between the Servicer and a Sub-Servicer or reference to actions
taken through a Sub-Servicer or otherwise, the Servicer shall remain obligated
and primarily liable to the Trustee and the Certificateholders for the servicing
and administering of the Mortgage Loans in accordance with the provisions of
Section 3.01 without diminution of such obligation or liability by virtue of
such Sub-Servicing Agreements or arrangements or by virtue of indemnification
from the Sub-Servicer and to the same extent and under the same terms and
conditions as if the Servicer alone were servicing and administering the
Mortgage Loans. The Servicer shall be entitled to enter into any agreement with
a Sub-Servicer for indemnification of the Servicer by such Sub-Servicer and
nothing contained in this Agreement shall be deemed to limit or modify such
indemnification.

      SECTION 3.05 No Contractual Relationship Between Sub-Servicers, the
Trustee or the Certificateholders. Any Sub-Servicing Agreement that may be
entered into and any other transactions or services relating to the Mortgage
Loans involving a Sub-Servicer in its capacity as such shall be deemed to be
between the Sub-Servicer and the Servicer alone, and the Trustee and the
Certificateholders shall not be deemed parties thereto and shall have no claims,
rights, obligations, duties or liabilities with respect to the Sub-Servicer
except as set forth in Section 3.06. The Servicer shall be solely liable for all
fees owed by it to any Sub-Servicer, irrespective of whether the Servicer's
compensation pursuant to this Agreement is sufficient to pay such fees.

                                       18

The foregoing provision shall not in any way limit a Sub-Servicer's obligation
to cure an omission or defect.

      SECTION 3.06 Assumption or Termination of Sub-Servicing Agreements by the
Trustee. In the event the Servicer shall for any reason no longer be the
Servicer (including by reason of the occurrence of a Servicer Event of Default),
the Trustee, its designee or other successor Servicer shall thereupon assume all
of the rights and obligations of the Servicer under each Sub-Servicing Agreement
that the Servicer may have entered into, unless the Trustee, such designee or
other successor Servicer elects to terminate any Sub-Servicing Agreement in
accordance with its terms as provided in Section 3.03. Upon such assumption, the
Trustee, its designee or the successor Servicer for the Trustee appointed
pursuant to Section 7.02 shall be deemed, subject to Section 3.03, to have
assumed all of the Servicer's interest therein and to have replaced the Servicer
as a party to each Sub-Servicing Agreement to the same extent as if each
Sub-Servicing Agreement had been assigned to the assuming party, except that (i)
the Servicer shall not thereby be relieved of any liability or obligations under
any Sub-Servicing Agreement that arose before it ceased to be the Servicer and
(ii) none of the Trustee, its designee or any successor Servicer shall be deemed
to have assumed any liability or obligation of the Servicer that arose before it
ceased to be the Servicer.

      The Servicer at its expense shall, upon request of the Trustee, deliver to
the assuming party all documents and records relating to each Sub-Servicing
Agreement and the Mortgage Loans then being serviced and an accounting of
amounts collected and held by or on behalf of it, and otherwise use its best
efforts to effect the orderly and efficient transfer of each Sub-Servicing
Agreement to the assuming party.

      The Servicing Fee payable to the Trustee as successor Servicer or other
successor Servicer shall be payable from payments received on the Mortgage Loans
in the amount and in the manner set forth in this Agreement.

      SECTION 3.07 Collection of Certain Mortgage Loan Payments. The Servicer
shall make reasonable efforts to collect all payments called for under the terms
and provisions of the Mortgage Loans, and shall, to the extent such procedures
shall be consistent with this Agreement and the terms and provisions of any
applicable insurance policies, follow such collection procedures as it would
follow with respect to mortgage loans comparable to the Mortgage Loans and held
for its own account. Consistent with the foregoing, the Servicer may in its
discretion (i) waive any late payment charge or, if applicable, any penalty
interest, or (ii) extend the due dates for the Monthly Payments due on a
Mortgage Note for a period of not greater than 180 days; provided, however, that
any extension pursuant to clause (ii) above shall not affect the amortization
schedule of any Mortgage Loan for purposes of any computation hereunder, except
as provided below. In the event of any such arrangement pursuant to clause (ii)
above, the Servicer shall make timely advances on such Mortgage Loan during such
extension pursuant to Section 4.03 and in accordance with the amortization
schedule of such Mortgage Loan without modification thereof by reason of such
arrangement. Notwithstanding the foregoing, in the event that any Mortgage Loan
is in default or, in the judgment of the Servicer, such default is reasonably
foreseeable, the Servicer, consistent with the standards set forth in Section
3.01, may also waive, modify or vary any term of such Mortgage Loan (including
modifications that would

                                       19

change the Mortgage Rate, forgive the payment of principal or interest,
capitalize past due Monthly Payments and outstanding Servicing Advances or
extend the final maturity date of such Mortgage Loan), accept payment from the
related Mortgagor of an amount less than the Stated Principal Balance in final
satisfaction of such Mortgage Loan (such payment, a "Short Pay-off"), or consent
to the postponement of strict compliance with any such term or otherwise grant
indulgence to any Mortgagor (any and all such waivers, modifications, variances,
forgiveness of principal or interest, postponements, or indulgences collectively
referred to herein as "forbearance"), provided, however, that in no event shall
the Servicer grant any such forbearance (other than as permitted by the second
sentence of this Section) with respect to any one Mortgage Loan more than once
in any 12 month period or more than three times over the life of such Mortgage
Loan. The Servicer's analysis supporting any forbearance and the conclusion that
any forbearance meets the standards of Section 3.01 shall be reflected in
writing in the Mortgage File.

      SECTION 3.08 Sub-Servicing Accounts. In those cases where a Sub-Servicer
is servicing a Mortgage Loan pursuant to a Sub-Servicing Agreement, the
Sub-Servicer will be required to establish and maintain one or more accounts
(collectively, the "Sub-Servicing Account"). The Sub-Servicing Account shall be
an Eligible Account and shall comply with all requirements of this Agreement
relating to the Custodial Account. The Sub-Servicer shall deposit in the
clearing account in which it customarily deposits payments and collections on
mortgage loans in connection with its mortgage loan servicing activities on a
daily basis, and in no event more than one Business Day after the Sub-Servicer's
receipt thereof, all proceeds of Mortgage Loans received by the Sub-Servicer
less its servicing compensation to the extent permitted by the Sub-Servicing
Agreement, and shall thereafter deposit such amounts in the Sub-Servicing
Account, in no event more than two Business Days after the receipt of such
amounts. The Sub-Servicer shall thereafter deposit such proceeds in the
Custodial Account or remit such proceeds to the Servicer for deposit in the
Custodial Account not later than two Business Days after the deposit of such
amounts in the Sub-Servicing Account. For purposes of this Agreement, the
Servicer shall be deemed to have received payments on the Mortgage Loans when
the Sub-Servicer receives such payments.

      SECTION 3.09 Collection of Taxes, Assessments and Similar Items; Servicing
Accounts. The Servicer shall establish and maintain, or cause to be established
and maintained, one or more accounts (the "Servicing Accounts"), into which all
collections from the Mortgagors (or related advances from Sub-Servicers) for the
payment of taxes, assessments, hazard insurance premiums and comparable items
for the account of the Mortgagors ("Escrow Payments") shall be deposited and
retained. Servicing Accounts shall be Eligible Accounts. The Servicer shall
deposit in the clearing account in which it customarily deposits payments and
collections on mortgage loans in connection with its mortgage loan servicing
activities on a daily basis, and in no event more than one Business Day after
the Servicer's receipt thereof, all Escrow Payments collected on account of the
Mortgage Loans and shall thereafter deposit such Escrow Payments in the
Servicing Accounts, in no event more than two Business Days after the receipt of
such Escrow Payments, all Escrow Payments collected on account of the Mortgage
Loans for the purpose of effecting the timely payment of any such items as
required under the terms of this Agreement. Withdrawals of amounts from a
Servicing Account may be made only to (i) effect payment of taxes, assessments,
hazard insurance premiums, and comparable items in a manner

                                       20

and at a time that assures that the lien priority of the Mortgage is not
jeopardized (or, with respect to the payment of taxes, in a manner and at a time
that avoids the loss of the Mortgaged Property due to a tax sale or the
foreclosure as a result of a tax lien); (ii) reimburse the Servicer (or a
Sub-Servicer to the extent provided in the related Sub-Servicing Agreement) out
of related collections for any advances made pursuant to Section 3.01 (with
respect to taxes and assessments) and Section 3.14 (with respect to hazard
insurance); (iii) refund to Mortgagors any sums as may be determined to be
overages; (iv) pay interest, if required and as described below, to Mortgagors
on balances in the Servicing Account; or (v) clear and terminate the Servicing
Account at the termination of the Servicer's obligations and responsibilities in
respect of the Mortgage Loans under this Agreement in accordance with Article
IX. In the event the Servicer shall deposit in a Servicing Account any amount
not required to be deposited therein, it may at any time withdraw such amount
from such Servicing Account, any provision herein to the contrary
notwithstanding. The Servicer will be responsible for the administration of the
Servicing Accounts and will be obligated to make Servicing Advances to such
accounts when and as necessary to avoid the lapse of insurance coverage on the
Mortgaged Property, or which the Servicer knows, or in the exercise of the
required standard of care of the Servicer hereunder 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 that jeopardizes the lien of the Mortgage Loan,
the Servicer will, within 10 business days of such notice, advance or cause to
be advanced funds necessary to discharge such lien on the Mortgaged Property. As
part of its servicing duties, the Servicer or Sub-Servicers shall pay to the
Mortgagors interest on funds in the Servicing Accounts, to the extent required
by law and, to the extent that interest earned on funds in the Servicing
Accounts is insufficient, to pay such interest from its or their own funds,
without any reimbursement therefor. The Servicer may pay to itself any excess
interest on funds in the Servicing Accounts, to the extent such action is in
conformity with the Servicing Standard, is permitted by law and such amounts are
not required to be paid to Mortgagors or used for any of the other purposes set
forth above.

      SECTION 3.10 Custodial Account and Certificate Account. (a) On behalf of
the Trust Fund, the Servicer shall establish and maintain, or cause to be
established and maintained, one or more accounts (such account or accounts, the
"Custodial Account"), held in trust for the benefit of the Trustee and the
Certificateholders. On behalf of the Trust Fund, the Servicer shall deposit or
cause to be deposited in the clearing account in which it customarily deposits
payments and collections on mortgage loans in connection with its mortgage loan
servicing activities on a daily basis, and in no event more than one Business
Day after the Servicer's receipt thereof, and shall thereafter deposit in the
Custodial Account, in no event more than two Business Days after the Servicer's
receipt thereof, as and when received or as otherwise required hereunder, the
following payments and collections received or made by it subsequent to the
Cut-off Date (other than in respect of principal or interest on the related
Mortgage Loans due on or before the Cut-off Date), or payments (other than
Principal Prepayments) received by it on or prior to the Cut-off Date but
allocable to a Due Period subsequent thereto:

            (i)     all payments on account of principal, including Principal
      Prepayments (but not Prepayment Charges), on the Mortgage Loans;

                                       21

            (ii)    all payments on account of interest (net of the related
      Servicing Fee) on each Mortgage Loan;

            (iii)   all Insurance Proceeds, Liquidation Proceeds (other than
      proceeds collected in respect of any particular REO Property and amounts
      paid in connection with a purchase of Mortgage Loans and REO Properties
      pursuant to Section 9.01) and Subsequent Recoveries;

            (iv)    any amounts required to be deposited pursuant to Section
      3.12 in connection with any losses realized on Permitted Investments with
      respect to funds held in the Custodial Account;

            (v)     any amounts required to be deposited by the Servicer
      pursuant to the second paragraph of Section 3.14(a) in respect of any
      blanket policy deductibles;

            (vi)    all proceeds of any Mortgage Loan repurchased or purchased
      in accordance with Section 2.03, Section 3.16 or Section 9.01;

            (vii)   all amounts required to be deposited in connection with
      shortfalls in principal amount of Qualified Substitute Mortgage Loans
      pursuant to Section 2.03; and

            (viii)  all Prepayment Charges collected by the Servicer and any
      Servicer Prepayment Charge Payment Amounts in connection with the
      Principal Prepayment of any of the Mortgage Loans.

      The foregoing requirements for deposit in the Custodial Account shall be
exclusive, it being understood and agreed that, without limiting the generality
of the foregoing, payments in the nature of Servicing Fees, late payment
charges, assumption fees, insufficient funds charges and ancillary income (other
than Prepayment Charges) need not be deposited by the Servicer in the Custodial
Account and may be retained by the Servicer as additional compensation. In the
event the Servicer shall deposit in the Custodial Account any amount not
required to be deposited therein, it may at any time withdraw such amount from
the Custodial Account, any provision herein to the contrary notwithstanding.

      (b)   On behalf of the Trust Fund, the Trustee shall establish and
maintain one or more accounts (such account or accounts, the "Certificate
Account"), held in trust for the benefit of the Trustee, the Trust Fund and the
Certificateholders. On behalf of the Trust Fund, the Servicer shall deliver to
the Trustee in immediately available funds for deposit in the Certificate
Account by 1:00 p.m. New York time (i) on the Servicer Remittance Date, that
portion of the Available Distribution Amount (calculated without regard to the
references in clause (2) of the definition thereof to amounts that may be
withdrawn from the Certificate Account) for the related Distribution Date then
on deposit in the Custodial Account and the amount of all Prepayment Charges
collected during the applicable Prepayment Period by the Servicer and Servicer
Prepayment Charge Payment Amounts in connection with the Principal Prepayment of
any of the Mortgage Loans then on deposit in the Custodial Account and the
amount of any funds reimbursable to an Advancing Person pursuant to Section 3.26
and (ii) on each Business Day as of the commencement of which the balance on
deposit in the Custodial Account exceeds $75,000

                                       22

following any withdrawals pursuant to the next succeeding sentence, the amount
of such excess, but only if the Custodial Account constitutes an Eligible
Account solely pursuant to clause (ii) of the definition of "Eligible Account."
If the balance on deposit in the Custodial Account exceeds $75,000 as of the
commencement of business on any Business Day and the Custodial Account
constitutes an Eligible Account solely pursuant to clause (ii) of the definition
of "Eligible Account," the Servicer shall, on or before 1:00 p.m. New York time
on such Business Day, withdraw from the Custodial Account any and all amounts
payable or reimbursable to the Depositor, the Servicer, the Trustee, the
Responsible Party, the Seller or any Sub-Servicer pursuant to Section 3.11 and
shall pay such amounts to the Persons entitled thereto.

      (c)   Funds in the Custodial Account and the Certificate Account may be
invested in Permitted Investments in accordance with the provisions set forth in
Section 3.12. The Servicer shall give notice to the Trustee of the location of
the Custodial Account maintained by it when established and prior to any change
thereof. The Trustee shall give notice to the Servicer and the Depositor of the
location of the Certificate Account when established and prior to any change
thereof.

      (d)   Funds held in the Custodial Account at any time may be delivered by
the Servicer to the Trustee for deposit in an account (which may be the
Certificate Account and must satisfy the standards for the Certificate Account
as set forth in the definition thereof) and for all purposes of this Agreement
shall be deemed to be a part of the Custodial Account (and in such event, the
Servicer shall provide the Trustee with written instructions regarding the
investment of such funds); provided, however, that the Trustee shall have the
sole authority to withdraw any funds held pursuant to this subsection (d). In
the event the Servicer shall deliver to the Trustee for deposit in the
Certificate Account any amount not required to be deposited therein, it may at
any time request in writing that the Trustee withdraw such amount from the
Certificate Account and remit to it any such amount, any provision herein to the
contrary notwithstanding. In no event shall the Trustee incur liability as a
result of withdrawals from the Certificate Account at the direction of the
Servicer in accordance with the immediately preceding sentence. In addition, the
Servicer shall deliver to the Trustee from time to time for deposit, and the
Trustee shall so deposit, in the Certificate Account:

            (i)     any Advances, as required pursuant to Section 4.03;

            (ii)    any amounts required to be deposited pursuant to Section
      3.23(d) or (f) in connection with any REO Property;

            (iii)   any amounts to be paid in connection with a purchase of
      Mortgage Loans and REO Properties pursuant to Section 9.01; and

            (iv)    any Compensating Interest required to be deposited pursuant
      to Section 3.24 in connection with any Prepayment Interest Shortfall.

      (e)   The Servicer shall deposit in the Custodial Account any amounts
required to be deposited pursuant to Section 3.12(b) in connection with losses
realized on Permitted

                                       23

Investments with respect to funds held in the Custodial Account (and the
Certificate Account to the extent that funds therein are deemed to be part of
the Custodial Account).

      SECTION 3.11 Withdrawals from the Custodial Account and Certificate
Account. (a) The Servicer shall, from time to time, make withdrawals from the
Custodial Account for any of the following purposes or as described in Section
4.03:

            (i)     to remit to the Trustee for deposit in the Certificate
      Account the amounts required to be so remitted pursuant to Section 3.10(b)
      or permitted to be so remitted pursuant to the first sentence of Section
      3.10(d);

            (ii)    subject to Section 3.16(d), to reimburse the Servicer for
      (a) any unreimbursed Advances to the extent of amounts received which
      represent Late Collections (net of the related Servicing Fees) of Monthly
      Payments, Liquidation Proceeds and Insurance Proceeds on Mortgage Loans
      with respect to which such Advances were made in accordance with the
      provisions of Section 4.03; (b) any unreimbursed Advances with respect to
      the final liquidation of a Mortgage Loan that are Nonrecoverable Advances,
      but only to the extent that Late Collections, Liquidation Proceeds and
      Insurance Proceeds received with respect to such Mortgage Loan are
      insufficient to reimburse the Servicer for such unreimbursed Advances; or
      (c) subject to Section 4.03(b), any unreimbursed Advances to the extent of
      funds held in the Collection Account for future distribution that were not
      included in Available Funds for the preceding Distribution Date;

            (iii)   subject to Section 3.16(d), to pay the Servicer or any
      Sub-Servicer, as applicable, (a) any unpaid Servicing Fees, (b) any
      unreimbursed Servicing Advances with respect to each Mortgage Loan, but
      only to the extent of any Late Collections, Liquidation Proceeds,
      Insurance Proceeds and Subsequent Recoveries received with respect to such
      Mortgage Loan, and (c) any Servicing Advances with respect to the final
      liquidation of a Mortgage Loan that are Nonrecoverable Advances, but only
      to the extent that Late Collections, Liquidation Proceeds and Insurance
      Proceeds received with respect to such Mortgage Loan are insufficient to
      reimburse the Servicer or any Sub-Servicer for Servicing Advances;

            (iv)    to pay to the Servicer as servicing compensation (in
      addition to the Servicing Fee) on the Servicer Remittance Date any
      interest or investment income earned on funds deposited in the Custodial
      Account;

            (v)     to pay to the Servicer, the Depositor, the Responsible Party
      or the Seller, as the case may be, with respect to each Mortgage Loan that
      has previously been purchased or replaced pursuant to Section 2.03 or
      Section 3.16(c) all amounts received thereon subsequent to the date of
      purchase or substitution, as the case may be;

            (vi)    to reimburse the Servicer for any Advance or Servicing
      Advance previously made which the Servicer has determined to be a
      Nonrecoverable Advance in accordance with the provisions of Section 4.03;

                                       24

            (vii)   to pay, or to reimburse the Servicer for Servicing Advances
      in respect of, expenses incurred in connection with any Mortgage Loan
      pursuant to Section 3.16(b);

            (viii)  to reimburse the Servicer or the Depositor for expenses
      incurred by or reimbursable to the Servicer or the Depositor, as the case
      may be, pursuant to Section 3.02(b) and Section 6.03;

            (ix)    to reimburse the Servicer (if the Servicer is not an
      Affiliate of the Originator) or the Trustee, as the case may be, for
      enforcement expenses reasonably incurred in respect of the breach or
      defect giving rise to the purchase obligation under Section 2.03 of this
      Agreement that were included in the Purchase Price of the Mortgage Loan,
      including any expenses arising out of the enforcement of the purchase
      obligation;

            (x)     to pay itself and Prepayment Interest Excess; and

            (xi)    to clear and terminate the Custodial Account pursuant to
      Section 9.01.

      The foregoing requirements for withdrawal from the Custodial Account shall
be exclusive. In the event the Servicer shall deposit in the Custodial Account
any amount not required to be deposited therein, it may at any time withdraw
such amount from the Custodial Account, any provision herein to the contrary
notwithstanding.

      The Servicer shall keep and maintain separate accounting, on a Mortgage
Loan by Mortgage Loan basis, for the purpose of justifying any withdrawal from
the Custodial Account, to the extent held by or on behalf of it, pursuant to
subclauses (ii), (iii), (iv), (v), (vi), (vii) and (viii) above. The Servicer
shall provide written notification to the Trustee, on or prior to the next
succeeding Servicer Remittance Date, upon making any withdrawals from the
Custodial Account pursuant to subclause (vi) above; provided that an Officers'
Certificate in the form described under Section 4.03(d) shall suffice for such
written notification to the Trustee in respect of subclause (vi) hereof.

      (b)   The Trustee shall, from time to time, make withdrawals from the
Certificate Account, for any of the following purposes, without priority:

            (i)     to make distributions to Certificateholders in accordance
      with Section 4.01;

            (ii)    to pay to itself amounts to which it is entitled pursuant to
      Section 8.05 or for Extraordinary Trust Fund Expenses;

            (iii)   to reimburse itself pursuant to Section 7.02;

            (iv)    to pay any amounts in respect of taxes pursuant to Section
      10.01(g)(iii);

            (v)     to pay to an Advancing Person reimbursements for Advances
      and/or Servicing Advances pursuant to Section 3.26; and

                                       25

            (vi)    to clear and terminate the Certificate Account pursuant to
      Section 9.01.

      SECTION 3.12 Investment of Funds in the Custodial Account and the
Certificate Account. (a) The Servicer may direct any depository institution
maintaining the Custodial Account and any REO Account to invest the funds on
deposit in such accounts (each such account, for the purposes of this Section
3.12 an "Investment Account") in one or more Permitted Investments bearing
interest or sold at a discount, and maturing, unless payable on demand, (i) no
later than the Business Day immediately preceding the date on which such funds
are required to be withdrawn from such account pursuant to this Agreement, if a
Person other than the Trustee is the obligor thereon, and (ii) no later than the
date on which such funds are required to be withdrawn from such account pursuant
to this Agreement, if the Trustee is the obligor thereon. Amounts in the
Certificate Account shall be held uninvested. All such Permitted Investments
shall be held to maturity, unless payable on demand. Any investment of funds in
an Investment Account shall be made in the name of the Trustee for the benefit
of the Certificateholders. The Trustee shall be entitled to sole possession
(except with respect to investment direction of funds held in the Custodial
Account or any REO Account and any income and gain realized thereon) over each
such investment, and any certificate or other instrument evidencing any such
investment shall be delivered directly to the Trustee or its agent, together
with any document of transfer necessary to transfer title to such investment to
the Trustee or its nominee. In the event amounts on deposit in an Investment
Account are at any time invested in a Permitted Investment payable on demand,
the party with investment discretion over such Investment Account shall:

            (x)     consistent with any notice required to be given thereunder,
      demand that payment thereon be made on the last day such Permitted
      Investment may otherwise mature hereunder in an amount equal to the lesser
      of (1) all amounts then payable thereunder and (2) the amount required to
      be withdrawn on such date; and

            (y)     demand payment of all amounts due thereunder promptly upon
      determination by a Responsible Officer of the Trustee that such Permitted
      Investment would not constitute a Permitted Investment in respect of funds
      thereafter on deposit in the Investment Account.

      (b)   All income and gain realized from the investment of funds deposited
in the Custodial Account and any REO Account held by or on behalf of the
Servicer, shall be for the benefit of the Servicer and shall be subject to its
withdrawal in accordance with Section 3.11 or Section 3.23, as applicable. The
Servicer shall deposit in the Custodial Account or any REO Account, as
applicable, the amount of any loss of principal incurred in respect of any such
Permitted Investment made with funds in such accounts immediately upon
realization of such loss.

      (c)   Except as otherwise expressly provided in this Agreement, if any
default occurs in the making of a payment due under any Permitted Investment, or
if a default occurs in any other performance required under any Permitted
Investment (of which a Responsible Officer of the Trustee obtains actual
knowledge), the Trustee may and, subject to Section 8.01 and Section 8.02(v),
upon the request of the Holders of Certificates representing more than 50% of
the

                                       26

Voting Rights allocated to any Class of Certificates, shall take such action as
may be appropriate to enforce such payment or performance, including the
institution and prosecution of appropriate proceedings.

      (d)   The Trustee or its Affiliates are permitted to receive additional
compensation that could be deemed to be in the Trustee's economic self-interest
for (i) serving as investment adviser, administrator, shareholder servicing
agent, custodian or sub-custodian with respect to certain of the Permitted
Investments and (ii) effecting or using Affiliates to effect transactions in
certain Permitted Investments. Such compensation shall not be considered an
amount that is reimbursable or payable to the Trustee pursuant to Section 3.11
or 3.12 or otherwise payable in respect of Extraordinary Trust Fund Expenses.

      SECTION 3.13 [Reserved].

      SECTION 3.14 Maintenance of Hazard Insurance and Errors and Omissions and
Fidelity Coverage. (a) The Servicer shall cause to be maintained for each
Mortgage Loan hazard insurance with extended coverage on the related Mortgaged
Property in an amount which is at least equal to the lesser of the current
principal balance of such Mortgage Loan and the amount necessary to fully
compensate for any damage or loss to the improvements that are a part of such
property on a replacement cost basis, in each case in an amount not less than
such amount as is necessary to avoid the application of any coinsurance clause
contained in the related hazard insurance policy. The Servicer shall also cause
to be maintained fire insurance with extended coverage on each REO Property in
an amount which is at least equal to the lesser of (i) the maximum insurable
value of the improvements which are a part of such property and (ii) the
outstanding principal balance of the related Mortgage Loan at the time it became
an REO Property. The Servicer will comply in the performance of this Agreement
with all reasonable rules and requirements of each insurer under any such hazard
policies. Any amounts to be collected by the Servicer under any such policies
(other than amounts to be applied to the restoration or repair of the property
subject to the related Mortgage or amounts to be released to the Mortgagor in
accordance with the procedures that the Servicer would follow in servicing loans
held for its own account, subject to the terms and conditions of the related
Mortgage and Mortgage Note) shall be deposited in the Custodial Account, subject
to withdrawal pursuant to Section 3.11, if received in respect of a Mortgage
Loan, or in the REO Account, subject to withdrawal pursuant to Section 3.23, if
received in respect of an REO Property. Any cost incurred by the Servicer in
maintaining any such insurance shall not, for the purpose of calculating
distributions to Certificateholders, be added to the unpaid principal balance of
the related Mortgage Loan, notwithstanding that the terms of such Mortgage Loan
so permit. It is understood and agreed that no earthquake or other additional
insurance is to be required of any Mortgagor other than pursuant to such
applicable laws and regulations as shall at any time be in force and as shall
require such additional insurance. If the Mortgaged Property or REO Property is
at any time in an area identified in the Federal Register by the Federal
Emergency Management Agency as having special flood hazards and flood insurance
has been made available, the Servicer will cause to be maintained a flood
insurance policy in respect thereof. Such flood insurance shall be in an amount
equal to the lesser of (i) the unpaid principal balance of the related Mortgage
Loan and (ii) the maximum amount of such insurance available for the

                                       27

related Mortgaged Property under the national flood insurance program (assuming
that the area in which such Mortgaged Property is located is participating in
such program).

      In the event that the Servicer shall obtain and maintain a blanket policy
with an insurer having a General Policy Rating of A:X or better in Best's Key
Rating Guide (or such other rating that is comparable to such rating) insuring
against hazard losses on all of the Mortgage Loans, it shall conclusively be
deemed to have satisfied its obligations as set forth in the first two sentences
of this Section 3.14, it being understood and agreed that such policy may
contain a deductible clause, in which case the Servicer shall, in the event that
there shall not have been maintained on the related Mortgaged Property or REO
Property a policy complying with the first two sentences of this Section 3.14,
and there shall have been one or more losses which would have been covered by
such policy, deposit to the Custodial Account from its own funds the amount not
otherwise payable under the blanket policy because of such deductible clause. In
connection with its activities as administrator and servicer of the Mortgage
Loans, the Servicer agrees to prepare and present, on behalf of itself, the
Trustee and Certificateholders, claims under any such blanket policy in a timely
fashion in accordance with the terms of such policy.

      (b)   The Servicer shall keep in force during the term of this Agreement a
policy or policies of insurance covering errors and omissions for failure in the
performance of the Servicer's obligations under this Agreement, which policy or
policies shall be in such form and amount that would meet the requirements of
Fannie Mae or Freddie Mac if it were the purchaser of the Mortgage Loans. The
Servicer shall also maintain a fidelity bond in the form and amount that would
meet the requirements of Fannie Mae or Freddie Mac. The Servicer shall be deemed
to have complied with this provision if an Affiliate of the Servicer has such
errors and omissions and fidelity bond coverage and, by the terms of such
insurance policy or fidelity bond, the coverage afforded thereunder extends to
the Servicer. Any such errors and omissions policy and fidelity bond shall by
its terms not be cancelable without thirty days prior written notice to the
Trustee. The Servicer shall also cause each Sub-Servicer to maintain a policy of
insurance covering errors and omissions and a fidelity bond which would meet
such requirements.

      SECTION 3.15 Enforcement of Due-On-Sale Clauses; Assumption Agreements.
The Servicer will, to the extent it has knowledge of any conveyance or
prospective conveyance of any Mortgaged Property by any Mortgagor (whether by
absolute conveyance or by contract of sale, and whether or not the Mortgagor
remains or is to remain liable under the Mortgage Note and/or the Mortgage),
exercise its rights to accelerate the maturity of such Mortgage Loan under the
"due-on-sale" clause, if any, applicable thereto; provided, however, that the
Servicer shall not be required to take such action if in its sole business
judgment the Servicer believes it is not in the best interests of the Trust Fund
and shall not exercise any 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, or if any of the other conditions set forth in the
proviso to the preceding sentence apply, the Servicer will enter into an
assumption and modification agreement from or with the person to whom such
property has been conveyed or is proposed to be conveyed, pursuant to which such
person becomes liable under the Mortgage Note and, to the extent permitted by
applicable state law, the Mortgagor remains liable thereon. The Servicer is also
authorized to enter into a substitution of liability agreement with such person,
pursuant to which the original Mortgagor is released from liability and such
person is substituted as the

                                       28

Mortgagor and becomes liable under the Mortgage Note, provided that no such
substitution shall be effective unless such person satisfies the underwriting
criteria of the Originator and has a credit risk rating at least equal to that
of the original Mortgagor. In connection with any assumption or substitution,
the Servicer shall apply the Originator's underwriting standards and follow such
practices and procedures as shall be normal and usual in its general mortgage
servicing activities and as it applies to other mortgage loans owned solely by
it. The Servicer shall not take or enter into any assumption and modification
agreement, however, unless (to the extent practicable in the circumstances) it
shall have received confirmation, in writing, of the continued effectiveness of
any applicable hazard insurance policy. Any fee collected by the Servicer in
respect of an assumption, modification or substitution of liability agreement
shall be retained by the Servicer as additional servicing compensation. In
connection with any such assumption, no material term of the Mortgage Note
(including but not limited to the related Mortgage Rate and the amount of the
Monthly Payment) may be amended or modified, except as otherwise required
pursuant to the terms thereof. The Servicer shall notify the Trustee that any
such substitution, modification or assumption agreement has been completed by
forwarding to the Trustee the executed original of such substitution,
modification or assumption agreement, which document shall be added to the
related Mortgage File and shall, for all purposes, be considered a part of such
Mortgage File to the same extent as all other documents and instruments
constituting a part thereof.

      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 by the terms of the Mortgage Note or any
assumption which the Servicer may be restricted by law from preventing, for any
reason whatever. For purposes of this Section 3.15, the term "assumption" is
deemed to also include a sale (of the Mortgaged Property) subject to the
Mortgage that is not accompanied by an assumption or substitution of liability
agreement.

      SECTION 3.16 Realization Upon Defaulted Mortgage Loans. (a) The Servicer
shall exercise its discretion, consistent with customary servicing procedures
and the terms of this Agreement, with respect to the enforcement and servicing
of defaulted Mortgage Loans in such manner as will maximize the receipt of
principal and interest with respect thereto, including, but not limited to, the
modification of such Mortgage Loan, or foreclosure upon the related Mortgaged
Property and disposition thereof.

      In furtherance of the foregoing, the Servicer shall use its best efforts,
consistent with Accepted Servicing Practices, to foreclose upon or otherwise
comparably convert the ownership of properties securing such of the Mortgage
Loans as come into and continue in default and as to which no satisfactory
arrangements can be made for collection of delinquent payments pursuant to
Section 3.07. The Servicer shall be responsible for all costs and expenses
incurred by it in any such proceedings; provided, however, that such costs and
expenses will be recoverable as Servicing Advances by the Servicer as
contemplated in Section 3.11 and Section 3.23. The foregoing is subject to the
provision that, in any case in which Mortgaged Property shall have suffered
damage from an Uninsured Cause, the Servicer shall not be required to expend its
own funds toward the restoration of such property unless it shall determine in
its discretion that such

                                       29

restoration will increase the proceeds of liquidation of the related Mortgage
Loan after reimbursement to itself for such expenses.

      (b)   Notwithstanding the foregoing provisions of this Section 3.16 or any
other provision of this Agreement, with respect to any Mortgage Loan as to which
the Servicer has received actual notice of, or has actual knowledge of, the
presence of any toxic or hazardous substance on the related Mortgaged Property,
the Servicer shall not, on behalf of the Trust Fund either (i) obtain title to
such Mortgaged Property as a result of or in lieu of foreclosure or otherwise,
or (ii) otherwise acquire possession of, or take any other action with respect
to, such Mortgaged Property, if, as a result of any such action, the Trustee,
the Trust Fund or the Certificateholders would be considered to hold title to,
to be a "mortgagee-in-possession" of, or to be an "owner" or "operator" of such
Mortgaged Property within the meaning of the Comprehensive Environmental
Response, Compensation and Liability Act of 1980, as amended from time to time,
or any comparable law, unless the Servicer has also previously determined, based
on its reasonable judgment and a report prepared by an Independent Person who
regularly conducts environmental audits using customary industry standards,
that:

            (1)     such Mortgaged Property is in compliance with applicable
      environmental laws or, if not, that it would be in the best economic
      interest of the Trust Fund to take such actions as are necessary to bring
      the Mortgaged Property into compliance therewith; and

            (2)     there are no circumstances present at such Mortgaged
      Property relating to the use, management or disposal of any hazardous
      substances, hazardous materials, hazardous wastes, or petroleum-based
      materials for which investigation, testing, monitoring, containment,
      clean-up or remediation could be required under any federal, state or
      local law or regulation, or that if any such materials are present for
      which such action could be required, that it would be in the best economic
      interest of the Trust Fund to take such actions with respect to the
      affected Mortgaged Property.

      The cost of the environmental audit report contemplated by this Section
3.16 shall be advanced by the Servicer, subject to the Servicer's right to be
reimbursed therefor from the Custodial Account as provided in Section
3.11(a)(ix), such right of reimbursement being prior to the rights of
Certificateholders to receive any amount in the Custodial Account received in
respect of the affected Mortgage Loan or other Mortgage Loans.

      If the Servicer determines, as described above, that it is in the best
economic interest of the Trust Fund to take such actions as are necessary to
bring any such Mortgaged Property into compliance with applicable environmental
laws, or to take such action with respect to the containment, clean-up or
remediation of hazardous substances, hazardous materials, hazardous wastes or
petroleum-based materials affecting any such Mortgaged Property, then the
Servicer shall take such action as it deems to be in the best economic interest
of the Trust Fund; provided that any amounts disbursed by the Servicer pursuant
to this Section 3.16(b) shall constitute Servicing Advances, subject to Section
4.03(d). The cost of any such compliance, containment, cleanup or remediation
shall be advanced by the Servicer, subject to the Servicer's right to be
reimbursed therefor from the Custodial Account as provided in Section
3.11(a)(iii) and (a)(ix),

                                       30

such right of reimbursement being prior to the rights of Certificateholders to
receive any amount in the Custodial Account received in respect of the affected
Mortgage Loan or other Mortgage Loans.

      (c)   The Servicer may, at its option, purchase a Mortgage Loan which has
become 90 or more days delinquent or for which the Servicer has accepted a deed
in lieu of foreclosure. Prior to purchase pursuant to this Section 3.16(c), the
Servicer shall be required to continue to make Advances pursuant to Section
4.03. The Servicer shall purchase such delinquent Mortgage Loan at a price equal
to the Purchase Price of such Mortgage Loan. Any such purchase of a Mortgage
Loan pursuant to this Section 3.16(c) shall be accomplished by deposit in the
Custodial Account of the amount of the Purchase Price. The Trustee shall
immediately effectuate the conveyance of such delinquent Mortgage Loan to the
Servicer to the extent necessary, including the prompt delivery of all
documentation to the Servicer. Notwithstanding the foregoing if the Servicer
purchases any delinquent Mortgage Loans pursuant to this Section 3.16(c), it
must purchase Mortgage Loans that are delinquent the greatest number of days
before it may purchase any that are delinquent any fewer number of days.

      (d)   Proceeds received in connection with any Final Recovery
Determination, as well as any recovery resulting from a partial collection of
Insurance Proceeds, Liquidation Proceeds or Subsequent Recoveries, in respect of
any Mortgage Loan, will be applied in the following order of priority: first, to
unpaid Servicing Fees; second, to reimburse the Servicer or any Sub-Servicer for
any related unreimbursed Servicing Advances pursuant to Section 3.11(a)(iii) and
Advances pursuant to Section 3.11(a)(ii); third, to accrued and unpaid interest
on the Mortgage Loan, to the date of the Final Recovery Determination, or to the
Due Date prior to the Distribution Date on which such amounts are to be
distributed if not in connection with a Final Recovery Determination; and
fourth, as a recovery of principal of the Mortgage Loan. The portion of the
recovery so allocated to unpaid Servicing Fees shall be reimbursed to the
Servicer or any Sub-Servicer pursuant to Section 3.11(a)(iii).

      SECTION 3.17 Trustee to Cooperate; Release of Mortgage Files. (a) Upon the
payment in full of any Mortgage Loan, or upon the receipt by the Servicer of a
notification that payment in full shall be escrowed in a manner customary for
such purposes, the Servicer shall immediately notify or cause to be notified the
Trustee by a certification in the form of Exhibit E or such form mutually agreed
upon by the Servicer and the Trustee (which certification shall include a
statement to the effect that all amounts received or to be received in
connection with such payment which are required to be deposited in the Custodial
Account pursuant to Section 3.10 have been or will be so deposited) of a
Servicing Officer and shall request delivery to it of the Mortgage File. Upon
receipt of such certification and request, the Trustee shall, within three
Business Days, release the related Mortgage File to the Servicer at no cost to
the Trustee or the Trust Fund. No expenses incurred in connection with any
instrument of satisfaction or deed of reconveyance shall be chargeable to the
Custodial Account or the Certificate Account.

      (b)   From time to time and as appropriate for the servicing or
foreclosure of any Mortgage Loan, including, for this purpose, collection under
any insurance policy relating to the Mortgage Loans, the Trustee shall, upon any
request made by or on behalf of the Servicer and delivery to the Trustee of a
Request for Release in the form of Exhibit E or such form mutually

                                       31

agreed upon by the Servicer and the Trustee, release the related Mortgage File
to the Servicer within three Business Days, and the Trustee shall, at the
direction of the Servicer, execute such documents as shall be necessary to the
prosecution of any such proceedings. Such Request for Release shall obligate the
Servicer to return each and every document previously requested from the
Mortgage File to the Trustee when the need therefor by the Servicer no longer
exists, unless (i) the Mortgage Loan has been liquidated and the Liquidation
Proceeds relating to the Mortgage Loan have been deposited in the Custodial
Account or (ii) the Mortgage File or such document has been delivered to an
attorney, or to a public trustee or other public official as required by law,
for purposes of initiating or pursuing legal action or other proceedings for the
foreclosure of the Mortgaged Property either judicially or non-judicially, and
the Servicer has delivered, or caused to be delivered, to the Trustee an
additional Request for Release certifying as to such liquidation or action or
proceedings. Upon the request of the Trustee, the Servicer shall provide notice
to the Trustee of the name and address of the Person to which such Mortgage File
or such document was delivered and the purpose or purposes of such delivery.
Upon receipt of a certificate of a Servicing Officer stating that such Mortgage
Loan was liquidated and that all amounts received or to be received in
connection with such liquidation that are required to be deposited into the
Custodial Account have been so deposited, or that such Mortgage Loan has become
an REO Property, any outstanding Requests for Release with respect to such
Mortgage Loan shall be released by the Trustee to the Servicer or its designee.

      (c)   Upon written certification of a Servicing Officer, the Trustee shall
execute and deliver to the Servicer or the Sub-Servicer, as the case may be, any
court pleadings, requests for trustee's sale or other documents necessary to the
foreclosure or trustee's sale in respect of a Mortgaged Property or to any legal
action brought to obtain judgment against any Mortgagor on the Mortgage Note or
Mortgage or to obtain a deficiency judgment, or to enforce any other remedies or
rights provided by the Mortgage Note or Mortgage or otherwise available at law
or in equity. Each such certification shall include a request that such
pleadings or documents be executed by the Trustee and a statement as to the
reason such documents or pleadings are required and that the execution and
delivery thereof by the Trustee will not invalidate or otherwise affect the lien
of the Mortgage, except for the termination of such a lien upon completion of
the foreclosure or trustee's sale.

      SECTION 3.18 Servicing Compensation. As compensation for the activities of
the Servicer hereunder, the Servicer shall be entitled to the Servicing Fee with
respect to each Mortgage Loan payable solely from payments of interest in
respect of such Mortgage Loan, subject to Section 3.24. In addition, the
Servicer shall be entitled to recover unpaid Servicing Fees out of Insurance
Proceeds, Liquidation Proceeds or Subsequent Recoveries to the extent permitted
by Section 3.11(a)(iii) and out of amounts derived from the operation and sale
of an REO Property to the extent permitted by Section 3.23. Except as provided
in Sections 3.26, the right to receive the Servicing Fee may not be transferred
in whole or in part except in connection with the transfer of all of the
Servicer's responsibilities and obligations under this Agreement; provided,
however, that the Servicer may pay from the Servicing Fee any amounts due to a
Sub-Servicer pursuant to a Sub-Servicing Agreement entered into under Section
3.02.

      Additional servicing compensation in the form of assumption fees, late
payment charges, insufficient funds charges, ancillary income or otherwise
(subject to Section 3.24 and other than

                                       32

Prepayment Charges) shall be retained by the Servicer only to the extent such
fees or charges are received by the Servicer. The Servicer shall also be
entitled pursuant to Section 3.11(a)(iv) to withdraw from the Custodial Account
and pursuant to Section 3.23(b) to withdraw from any REO Account, as additional
servicing compensation, interest or other income earned on deposits therein,
subject to Section 3.12 and Section 3.24. The Servicer shall be required to pay
all expenses incurred by it in connection with its servicing activities
hereunder (including premiums for the insurance required by Section 3.14, to the
extent such premiums are not paid by the related Mortgagors or by a
Sub-Servicer, servicing compensation of each Sub-Servicer, and to the extent
provided herein in Section 8.05, the expenses of the Trustee) and shall not be
entitled to reimbursement therefor except as specifically provided herein.

      The Servicer shall be entitled to any Prepayment Interest Excess, which it
may withdraw from the Custodial Account pursuant to Section 3.11(a)(x).

      SECTION 3.19 Reports to the Trustee and Others; Custodial Account
Statements. Not later than twenty days after each Distribution Date, the
Servicer shall forward to the Trustee (upon the Trustee's request) and the
Depositor the most current available bank statement for the Custodial Account.
Copies of such statement shall be provided by the Trustee to any
Certificateholder and to any Person identified to the Trustee as a prospective
transferee of a Certificate, upon request at the expense of the requesting
party, provided such statement is delivered by the Servicer to the Trustee.

      SECTION 3.20 [Reserved].

      SECTION 3.21 [Reserved].

      SECTION 3.22 Access to Certain Documentation. The Servicer shall provide
to the Office of Thrift Supervision, the FDIC, and any other federal or state
banking or insurance regulatory authority that may exercise authority over any
Certificateholder or Certificate Owner, access to the documentation in the
Servicer's possession regarding the Mortgage Loans required by applicable laws
and regulations. Such access shall be afforded without charge, but only upon
reasonable request and during normal business hours at the offices of the
Servicer designated by it. In addition, access to the documentation in the
Servicer's possession regarding the Mortgage Loans will be provided to any
Certificateholder or Certificate Owner, the Trustee and to any Person identified
to the Servicer as a prospective transferee of a Certificate; provided, however,
that providing access to such Person will not violate any applicable laws, upon
reasonable request during normal business hours at the offices of the Servicer
designated by it at the expense of the Person requesting such access.

      SECTION 3.23 Title, Management and Disposition of REO Property. (a) The
deed or certificate of sale of any REO Property shall be taken in the name of
the Trustee, or its nominee, on behalf of the Trust Fund and for the benefit of
the Certificateholders. The Servicer, on behalf of REMIC I, shall either sell
any REO Property prior to the end of the third taxable year after REMIC I
acquires ownership of such REO Property for purposes of Section 860G(a)(8) of
the Code or request from the Internal Revenue Service, no later than 60 days
before the day on which the three-year grace period would otherwise expire, an
extension of the three-year grace

                                       33

period, unless the Servicer shall have delivered to the Trustee an Opinion of
Counsel, addressed to the Trustee and the Depositor, to the effect that the
holding by REMIC I of such REO Property subsequent to three years after its
acquisition will not result in the imposition on any Trust REMIC of taxes on
"prohibited transactions" thereof, as defined in Section 860F of the Code, or
cause any Trust REMIC to fail to qualify as a REMIC under Federal law at any
time that any Certificates are outstanding. The Servicer shall manage, conserve,
protect and operate each REO Property for the Certificateholders solely for the
purpose of its prompt disposition and sale in a manner which does not cause such
REO Property to fail to qualify as "foreclosure property" within the meaning of
Section 860G(a)(8) of the Code or result in the receipt by any Trust REMIC of
any "income from non-permitted assets" within the meaning of Section
860F(a)(2)(B) of the Code, or any "net income from foreclosure property" which
is subject to taxation under the REMIC Provisions.

      (b)   The Servicer shall segregate and hold all funds collected and
received in connection with the operation of any REO Property separate and apart
from its own funds and general assets and shall establish and maintain, or cause
to be established and maintained, with respect to REO Properties, an account
held in trust for the Trustee for the benefit of the Certificateholders (the
"REO Account"), which shall be an Eligible Account. The Servicer shall be
permitted to allow the Custodial Account to serve as the REO Account, subject to
separate ledgers for each REO Property. The Servicer shall be entitled to retain
or withdraw any interest income paid on funds deposited in the REO Account.

      (c)   The Servicer shall have the sole discretion to determine whether an
immediate sale of an REO Property or continued management of such REO Property
is in the best interests of the Certificateholders. In furtherance of the
foregoing, the Servicer shall have full power and authority, subject only to the
specific requirements and prohibitions of this Agreement, to do any and all
things in connection with any REO Property as are consistent with the manner in
which the Servicer manages and operates similar property owned by the Servicer
or any of its Affiliates, all on such terms and for such period as the Servicer
deems to be in the best interests of Certificateholders. In connection
therewith, the Servicer shall deposit, or cause to be deposited in the clearing
account in which it customarily deposits payments and collections on mortgage
loans in connection with its mortgage loan servicing activities on a daily
basis, and in no event more than one Business Day after the Servicer's receipt
thereof, and shall thereafter deposit in the REO Account, in no event more than
two Business Days after the Servicer's receipt thereof, all revenues received by
it with respect to an REO Property and shall withdraw therefrom funds necessary
for the proper operation, management and maintenance of such REO Property
including, without limitation:

            (i)     all insurance premiums due and payable in respect of such
      REO Property;

            (ii)    all real estate taxes and assessments in respect of such REO
      Property that may result in the imposition of a lien thereon; and

            (iii)   all costs and expenses necessary to maintain such REO
      Property.

                                       34

      To the extent that amounts on deposit in the REO Account with respect to
an REO Property are insufficient for the purposes set forth in clauses (i)
through (iii) above with respect to such REO Property, the Servicer shall
advance from its own funds such amount as is necessary for such purposes if, but
only if, the Servicer would make such advances if the Servicer owned the REO
Property and if in the Servicer's judgment, the payment of such amounts will be
recoverable from the rental or sale of the REO Property.

      Notwithstanding the foregoing, the Servicer shall not and the Trustee
shall not knowingly authorize the Servicer to:

            (i)     authorize the Trust Fund to enter into, renew or extend any
      New Lease with respect to any REO Property, if the New Lease by its terms
      will give rise to any income that does not constitute Rents from Real
      Property;

            (ii)    authorize any amount to be received or accrued under any New
      Lease other than amounts that will constitute Rents from Real Property;

            (iii)   authorize any construction on any REO Property, other than
      the completion of a building or other improvement thereon, and then only
      if more than ten percent of the construction of such building or other
      improvement was completed before default on the related Mortgage Loan
      became imminent, all within the meaning of Section 856(e)(4)(B) of the
      Code; or

            (iv)    authorize any Person to Directly Operate any REO Property on
      any date more than 90 days after its date of acquisition by the Trust
      Fund;

unless, in any such case, the Servicer has obtained an Opinion of Counsel,
provided to the Servicer and the Trustee, to the effect that such action will
not cause such REO Property to fail to qualify as "foreclosure property" within
the meaning of Section 860G(a)(8) of the Code at any time that it is held by
REMIC I, in which case the Servicer may take such actions as are specified in
such Opinion of Counsel.

      The Servicer may contract with any Independent Contractor for the
operation and management of any REO Property, provided that:

            (i)     the terms and conditions of any such contract shall not be
      inconsistent herewith;

            (ii)    any such contract shall require, or shall be administered to
      require, that the Independent Contractor pay all costs and expenses
      incurred in connection with the operation and management of such REO
      Property, including those listed above and remit all related revenues (net
      of such costs and expenses) to the Servicer as soon as practicable, but in
      no event later than thirty days following the receipt thereof by such
      Independent Contractor;

            (iii)   none of the provisions of this Section 3.23(c) relating to
      any such contract or to actions taken through any such Independent
      Contractor shall be deemed to relieve

                                       35

      the Servicer of any of its duties and obligations to the Trustee on behalf
      of the Certificateholders with respect to the operation and management of
      any such REO Property; and

            (iv)   the Servicer shall be obligated with respect thereto to the
      same extent as if it alone were performing all duties and obligations in
      connection with the operation and management of such REO Property.

      The Servicer shall be entitled to enter into any agreement with any
Independent Contractor performing services for it related to its duties and
obligations hereunder for indemnification of the Servicer by such Independent
Contractor, and nothing in this Agreement shall be deemed to limit or modify
such indemnification. The Servicer shall be solely liable for all fees owed by
it to any such Independent Contractor, irrespective of whether the Servicer's
compensation pursuant to Section 3.18 is sufficient to pay such fees; provided,
however, that to the extent that any payments made by such Independent
Contractor would constitute Servicing Advances if made by the Servicer, such
amounts shall be reimbursable as Servicing Advances made by the Servicer.

      (d)   In addition to the withdrawals permitted under Section 3.23(c), the
Servicer may from time to time make withdrawals from the REO Account for any REO
Property: (i) to pay itself or any Sub-Servicer unpaid Servicing Fees in respect
of the related Mortgage Loan; and (ii) to reimburse itself or any Sub-Servicer
for unreimbursed Servicing Advances and Advances made in respect of such REO
Property or the related Mortgage Loan. On the Servicer Remittance Date, the
Servicer shall withdraw from each REO Account maintained by it and deposit into
the Certificate Account in accordance with Section 3.10(d)(ii), for distribution
on the related Distribution Date in accordance with Section 4.01, the income
from the related REO Property received during the prior calendar month, net of
any withdrawals made pursuant to Section 3.23(c) or this Section 3.23(d).

      (e)   Subject to the time constraints set forth in Section 3.23(a), each
REO Disposition shall be carried out by the Servicer at such price and upon such
terms and conditions as the Servicer shall deem necessary or advisable, as shall
be normal and usual in its Accepted Servicing Practices.

      (f)   The proceeds from the REO Disposition, net of any amount required by
law to be remitted to the Mortgagor under the related Mortgage Loan and net of
any payment or reimbursement to the Servicer or any Sub-Servicer as provided
above, shall be deposited in the Certificate Account in accordance with Section
3.10(d)(ii) on the Servicer Remittance Date in the month following the receipt
thereof for distribution on the related Distribution Date in accordance with
Section 4.01. Any REO Disposition shall be for cash only (unless changes in the
REMIC Provisions made subsequent to the Startup Day allow a sale for other
consideration).

      (g)   The Servicer shall file information returns with respect to the
receipt of mortgage interest received in a trade or business, reports of
foreclosures and abandonments of any Mortgaged Property and cancellation of
indebtedness income with respect to any Mortgaged Property as required by
Sections 6050H, 6050J and 6050P of the Code, respectively. Such

                                       36

reports shall be in form and substance sufficient to meet the reporting
requirements imposed by such Sections 6050H, 6050J and 6050P of the Code.

      SECTION 3.24 Obligations of the Servicer in Respect of Prepayment Interest
Shortfalls. Not later than 1:00 p.m. New York time on each Servicer Remittance
Date, the Servicer shall remit to the Distribution Account an amount
("Compensating Interest") equal to the lesser of (A) the aggregate of the
Prepayment Interest Shortfalls for the related Distribution Date resulting from
Principal Prepayment in full or in part during the related Due Period and (B)
its aggregate Servicing Fee received in the related Due Period and any interest
or investment income earned on funds deposited in the Custodial Account and any
Prepayment Interest Excess earned during the related Prepayment Period. The
Servicer shall not have the right to reimbursement for any amounts remitted to
the Trustee in respect of Compensating Interest. Such amounts so remitted shall
be included in the Available Distribution Amount and distributed therewith on
the next Distribution Date. The Servicer shall not be obligated to pay
Compensating Interest with respect to Relief Act Interest Shortfall.

      SECTION 3.25 Obligations of the Servicer in Respect of Mortgage Rates and
Monthly Payments. In the event that a shortfall in any collection on or
liability with respect to any Mortgage Loan results from or is attributable to
adjustments to Mortgage Rates, Monthly Payments or Stated Principal Balances
that were made by the Servicer in a manner not consistent with the terms of the
related Mortgage Note applicable laws, regulations and rulings and this
Agreement, the Servicer, upon discovery or receipt of notice thereof, shall
immediately deliver to the Trustee for deposit in the Certificate Account from
its own funds the amount of any such shortfall and shall indemnify and hold
harmless the Trust Fund, the Trustee, the Depositor and any successor Servicer
in respect of any such liability. Such indemnities shall survive the termination
or discharge of this Agreement. Notwithstanding the foregoing, this Section 3.25
shall not limit the ability of the Servicer to seek recovery of any such amounts
from the related Mortgagor under the terms of the related Mortgage Note, as
permitted by law.

      SECTION 3.26 Advance Facility. (a) The Servicer is hereby authorized to
enter into a financing or other facility (any such arrangement an "Advance
Facility") with any Person which provides that such Person (an "Advancing
Person") may fund Advances and/or Servicing Advances to the Trust Fund under
this Agreement, although no such facility shall reduce or otherwise affect the
Servicer's obligation to fund such Advances and/or Servicing Advances. If the
Servicer enters into such an Advance Facility pursuant to this Section 3.26,
upon reasonable request of the Advancing Person, the Trustee shall execute a
letter of acknowledgment, confirming its receipt of notice of the existence of
such Advance Facility. To the extent that an Advancing Person funds any Advance
or any Servicing Advance and the Servicer provides the Trustee with an Officers'
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 3.26(b). Such
Officers' Certificate must specify the amount of the reimbursement, the Section
of this Agreement that permits the applicable Advance or Servicing Advance to be
reimbursed and the section(s) of the Advance Facility that entitle the Advancing
Person to request reimbursement from the Trustee, rather than the Servicer or
proof of an Event of Default under the Advance Facility. The Trustee shall have
no duty or liability with respect to any calculation of any reimbursement to be
paid to an Advancing Person

                                       37

and shall be entitled to rely without independent investigation on the Advancing
Person's notice provided pursuant to this Section 3.26. The Trustee shall have
no responsibility to track or monitor the administration of the Advance
Facility. An Advancing Person whose obligations hereunder are limited to the
funding of Advances and/or Servicing Advances shall not be required to meet the
qualifications of the Servicer or a Sub-Servicer pursuant to Section 3.02 hereof
and will not be deemed to be a Sub-Servicer under this Agreement.

      (b)   If an advancing facility is entered into, then the Servicer shall
not be permitted to reimburse itself therefor under Section 3.11(a)(ii), Section
3.11(a)(iii) and Section 3.11(a)(vi) prior to the remittance to the Trust Fund,
but instead the Servicer shall remit such amounts in accordance with the
documentation establishing the Advance Facility to such Advancing Person or to a
trustee, agent or custodian (an "Advance Facility Trustee") designated by such
Advancing Person. The Trustee is hereby authorized to pay to the Advancing
Person, reimbursements for Advances and Servicing Advances from the Certificate
Account to the same extent the Servicer would have been permitted to reimburse
itself for such Advances and/or Servicing Advances in accordance with Section
3.11(a)(ii), Section 3.11(a)(iii) and Section 3.11(a)(vi), as the case may be,
had the Servicer itself funded such Advance or Servicing Advance. The Trustee is
hereby authorized to pay directly to the Advancing Person such portion of the
Servicing Fee as the parties to any advancing facility agree in writing.

      (c)   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.

      (d)   Any amendment to this Section 3.26 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 3.26, including amendments to
add provisions relating to a successor Servicer, may be entered into by the
Trustee and the Servicer without the consent of any Certificateholder,
notwithstanding anything to the contrary in this Agreement; provided, however,
such amendment shall otherwise comply with Section 13.01 hereof. All costs and
expenses (including attorneys' fees) of each party hereto related to such
amendment shall be borne by the Servicer without reimbursement from the Trust
Fund.

      SECTION 3.27 Net WAC Rate Carryover Reserve Account. (a) No later than the
Closing Date, the Trustee shall establish and maintain with itself, a separate,
segregated trust account (the "Net WAC Rate Carryover Reserve Account") titled,
"Net WAC Rate Carryover Reserve Account, Wells Fargo Bank, N.A., as Trustee, in
trust for the registered holders of Carrington Mortgage Loan Trust, Series
2006-OPT1, Asset Backed Pass-Through Certificates." On the Business Day prior to
each Distribution Date, the Trustee will deposit any amounts received under the
Cap Contracts into the Net WAC Carryover Reserve Account. All amounts deposited
in the Net WAC Rate Carryover Reserve Account shall be distributed to the
Holders of the Class A Certificates and the Mezzanine Certificates in the manner
set forth in Section 4.01(a)(4).

      (b)   On each Distribution Date as to which there is a Net WAC Rate
Carryover Amount payable to the Class A Certificates or the Mezzanine
Certificates, the Trustee has been directed by the Class CE Certificateholders
to, and therefore will, deposit into the Net WAC Rate

                                       38

Carryover Reserve Account the amounts described in Section 4.01(a)(4), rather
than distributing such amounts to the Class CE Certificateholders. On each such
Distribution Date, the Trustee shall hold all such amounts for the benefit of
the Holders of the Class A Certificates and the Mezzanine Certificates, and will
distribute such amounts to the Holders of the Class A Certificates and the
Mezzanine Certificates in the amounts and priorities set forth in Section
4.01(a)(4).

      (c)   For federal and state income tax purposes, the Class CE
Certificateholders will be deemed to be the owners of the Net WAC Rate Carryover
Reserve Account and amounts deposited into the Net WAC Rate Carryover Reserve
Account (other than amounts paid on the Cap Contracts) shall be treated as
amounts distributed by REMIC II to the Holders of the Class CE Certificates.
Upon the termination of the Trust Fund, or the payment in full of the Class A
Certificates and the Mezzanine Certificates, all amounts remaining on deposit in
the Net WAC Rate Carryover Reserve Account will be released by the Trust Fund
and distributed to the Class CE Certificateholders or their designees. The Net
WAC Rate Carryover Reserve Account will be part of the Trust Fund but not part
of any REMIC and any payments to the Holders of the Class A Certificates or the
Mezzanine Certificates of Net WAC Rate Carryover Amounts will not be payments
with respect to a "regular interest" in a REMIC within the meaning of Code
Section 860(G)(a)(1).

      (d)   By accepting a Class CE Certificate, each Class CE Certificateholder
hereby agrees to direct the Trustee, and the Trustee hereby is directed, to
deposit into the Net WAC Rate Carryover Reserve Account the amounts described
above on each Distribution Date as to which there is any Net WAC Rate Carryover
Amount rather than distributing such amounts to the Class CE Certificateholders.
By accepting a Class CE Certificate, each Class CE Certificateholder further
agrees that such direction is given for good and valuable consideration, the
receipt and sufficiency of which is acknowledged by such acceptance.

      (e)   Amounts on deposit in the Net WAC Rate Carryover Reserve Account
shall remain uninvested.

      (f)   For federal tax return and information reporting, the right of the
Holders of the Class A Certificates and the Mezzanine Certificates to receive
payments from the Net WAC Rate Carryover Reserve Account in respect of any Net
WAC Rate Carryover Amount each shall be assigned a de minimis value.

      SECTION 3.28 Solicitations. From and after the Closing Date, the Servicer
agrees that it will not take any action or permit or cause any action to be
taken by any of its agents and Affiliates, or by any independent contractors or
independent mortgage brokerage companies on the Servicer's behalf, to
personally, by telephone, mail or electronic mail, solicit the Mortgagor under
any Mortgage Loan for the purpose of refinancing such Mortgage Loan; provided,
that the Servicer may solicit any Mortgagor for whom the Servicer has received a
request for verification of mortgage, a request for demand for payoff, a
mortgagor initiated written or verbal communication indicating a desire to
prepay the related Mortgage Loan, another mortgage company has pulled a credit
report on the mortgagor or the mortgagor initiates a title search; provided
further, it is understood and agreed that promotions undertaken by the Servicer
or any

                                       39

of its Affiliates which (i) concern optional insurance products or other
additional products or (ii) are directed to the general public at large,
including, without limitation, mass mailings based on commercially acquired
mailing lists, newspaper, radio and television advertisements shall not
constitute solicitation under this Section, nor is the Servicer prohibited from
responding to unsolicited requests or inquiries made by a Mortgagor or an agent
of a Mortgagor. Furthermore, the Servicer shall be permitted to include in its
monthly statements to borrowers or otherwise, statements regarding the
availability of the Servicer's counseling services with respect to refinancing
mortgage loans.

            increased by such amount;

                    (ii)  second, to the Holders of REMIC I Regular Interests,

            allocated as follows:

                    Regular Interest I-LTAA, until the Uncertificated Balance of

      undistributed Net WAC Rate Carryover Amount, but only to the extent of
      amounts remaining under the Mezzanine Cap Contract; and

            (E)     to the Class A Certificates and Mezzanine Certificates from
      Net Monthly Excess Cash Flow, any related unpaid Net WAC Carryover Amount
      (after taking into account distributions pursuant to (A) through (D)
      above), distributed in the following order of priority: (i) to the Class A
      Certificates, on a pro rata basis based first on the outstanding
      certificate principal balance immediately prior to the Distribution Date,
      and second on such remaining undistributed Net WAC Carryover Amount, (ii)
      sequentially to the Mezzanine Certificates any such remaining
      undistributed Net WAC Carryover Amount for each class.

      (b)   On each Distribution Date, the Trustee shall withdraw any amounts
then on deposit in the Certificate Account that represent Prepayment Charges
collected by the Servicer, during the related Prepayment Period in connection
with the Principal Prepayment of any of the Mortgage Loans or any Servicer
Prepayment Charge Payment Amount and shall distribute such amounts to the
Holders of the Class P Certificates. Such distributions shall not be applied to
reduce the Certificate Principal Balance of the Class P Certificates.

      Following the foregoing distributions, an amount equal to the amount of
Subsequent Recoveries shall be applied to increase the Certificate Principal
Balance of the Class of

                                       44

Certificates with the Highest Priority up to the extent of such Realized Losses
previously allocated to that Class of Certificates pursuant to Section 4.04. An
amount equal to the amount of any remaining Subsequent Recoveries shall be
applied to increase the Certificate Principal Balance of the Class of
Certificates with the next Highest Priority, up to the amount of such Realized
Losses previously allocated to that Class of Certificates pursuant to Section
4.04. Holders of such Certificates will not be entitled to any distribution in
respect of interest on the amount of such increases for any Interest Accrual
Period preceding the Distribution Date on which such increase occurs. Any such
increases shall be applied to the Certificate Principal Balance of each
Certificate of such Class in accordance with its respective Percentage Interest.

      (c)   All distributions made with respect to each Class of Certificates on
each Distribution Date shall be allocated pro rata among the outstanding
Certificates in such Class based on their respective Percentage Interests.
Payments in respect of each Class of Certificates on each Distribution Date
shall be made to the Holders of the respective Class of record on the related
Record Date (except as otherwise provided in Section 4.01(e) or Section 9.01
respecting the final distribution on such Class), based on the aggregate
Percentage Interest represented by their respective Certificates, and shall be
made by wire transfer of immediately available funds to the account of any such
Holder at a bank or other entity having appropriate facilities therefor, if such
Holder shall (i) own Certificates having denominations aggregating at least
$1,000,000 and (ii) have so notified the Trustee in writing at least five
Business Days prior to the Record Date immediately prior to such Distribution
Date, or otherwise by check mailed by first class mail to the address of such
Holder appearing in the Certificate Register. The final distribution on each
Certificate shall be made in like manner, but only upon presentment and
surrender of such Certificate at the office of the Trustee maintained for such
purpose pursuant to Section 8.12 or such other location specified in the notice
to Certificateholders of such final distribution.

      Each distribution with respect to a Book-Entry Certificate shall be paid
to the Depository, as Holder thereof, and the Depository shall be responsible
for crediting the amount of such distribution to the accounts of its Depository
Participants in accordance with its normal procedures. Each Depository
Participant shall be responsible for disbursing such distribution to the
Certificate Owners that it represents and to each indirect participating
brokerage firm (a "brokerage firm" or "indirect participating firm") for which
it acts as agent. Each brokerage firm shall be responsible for disbursing funds
to the Certificate Owners that it represents. None of the Trustee, the Depositor
or the Servicer shall have any responsibility therefor except as otherwise
provided by this Agreement or applicable law.

      (d)   The rights of the Certificateholders to receive distributions in
respect of the Certificates, and all interests of the Certificateholders in such
distributions, shall be as set forth in this Agreement. None of the Holders of
any Class of Certificates, the Trustee or the Servicer shall in any way be
responsible or liable to the Holders of any other Class of Certificates in
respect of amounts properly previously distributed on the Certificates.

      (e)   Except as otherwise provided in Section 9.01, whenever the Trustee
expects that the final distribution with respect to any Class of Certificates
will be made on the next Distribution Date, the Trustee shall, no later than
three (3) days before the related Distribution

                                       45

Date (to the extent that an accurate Remittance Report is received in a timely
manner by the Trustee), mail to each Holder on such date of such Class of
Certificates a notice to the effect that:

                    (i)   the Trustee expects that the final distribution with
            respect to such Class of Certificates will be made on such
            Distribution Date but only upon presentation and surrender of such
            Certificates at the office of the Trustee therein specified, and

                    (ii)  no interest shall accrue on such Certificates from and
            after the end of the related Interest Accrual Period.

      Any funds not distributed to any Holder or Holders of Certificates of such
Class on such Distribution Date because of the failure of such Holder or Holders
to tender their Certificates shall, on such date, be set aside and held in trust
by the Trustee and credited to the account of the appropriate non-tendering
Holder or Holders. If any Certificates as to which notice has been given
pursuant to this Section 4.01(e) shall not have been surrendered for
cancellation within six months after the time specified in such notice, the
Trustee shall mail a second notice to the remaining non-tendering
Certificateholders to surrender their Certificates for cancellation in order to
receive the final distribution with respect thereto. If within one year after
the second notice all such Certificates shall not have been surrendered for
cancellation, the Trustee shall, directly or through an agent, mail a final
notice to the remaining non-tendering Certificateholders concerning surrender of
their Certificates and shall continue to hold any remaining funds for the
benefit of non-tendering Certificateholders. The costs and expenses of
maintaining the funds in trust and of contacting such Certificateholders shall
be paid out of the assets held in trust for such Certificateholders. If within
one year after the final notice any such Certificates shall not have been
surrendered for cancellation, the Trustee shall pay to Bear, Stearns & Co. Inc.,
as representative for the underwriters, in accordance with its wiring
instructions, all such amounts, and all rights of non-tendering
Certificateholders in or to such amounts shall thereupon cease. No interest
shall accrue or be payable to any Certificateholder on any amount held in trust
by the Trustee as a result of such Certificateholder's failure to surrender its
Certificate(s) for final payment thereof in accordance with this Section
4.01(e). Any such amounts held in trust by the Trustee shall be held in an
Eligible Account and shall be held uninvested.

      (f)   Notwithstanding anything to the contrary herein, (i) in no event
shall the Certificate Principal Balance of a Class A Certificate or a Mezzanine
Certificate be reduced more than once in respect of any particular amount
allocated to such Certificate in respect of Realized Losses pursuant to Section
4.04 and (ii) in no event shall the Uncertificated Balance of a REMIC I Regular
Interest be reduced more than once in respect of any particular amount both (a)
allocated to such REMIC I Regular Interest in respect of Realized Losses
pursuant to Section 4.04 and (b) distributed on such REMIC I Regular Interest in
reduction of the Uncertificated Balance thereof pursuant to this Section 4.01.

      SECTION 4.03 Remittance Reports; Advances. (a) On the third Business Day
following each Determination Date but in no event later than the 20th day of
each month (or if such 20th day is not a Business Day, the preceding Business

(or by such other means as the Servicer and the Trustee may agree from time to
time) a Remittance Report with respect to the related Distribution Date. On the
same date, the Servicer shall electronically transmit to the Trustee (in a
format acceptable to the Trustee), a data file containing the information set
forth in such Remittance Report (including but not limited to the date elements
specified in Schedule 4 hereto or in such form mutually agreed upon by the

respect of the related Distribution Date, the aggregate amount of Advances
outstanding after giving effect to such Advances, and the aggregate amount of
Nonrecoverable Advances in respect of such Distribution Date and (ii) such other
information with respect to the Mortgage Loans as the Trustee may reasonably
require to perform the calculations necessary to make the distributions
contemplated by Section 4.01 and to prepare the statements to Certificateholders
contemplated by Section 4.02. The Trustee shall not be responsible to recompute,
recalculate or verify any information provided to it by the Servicer.

      (b)   The amount of Advances to be made by the Servicer for any
Distribution Date shall equal, subject to Section 4.03(d), the sum of, (i) the
aggregate amount of Monthly Payments (with each interest portion thereof net of
the related Servicing Fee), due on the related Due Date in respect of the
Mortgage Loans, which Monthly Payments were delinquent as of the close of
business on the related Determination Date and (ii) with respect to each REO
Property,

                                       50

which REO Property was acquired during or prior to the related Prepayment Period
and as to which REO Property an REO Disposition did not occur during the related
Prepayment Period, an amount equal to the excess, if any, of the REO Imputed
Interest on such REO Property for the most recently ended calendar month, over
the net income from such REO Property transferred to the Certificate Account
pursuant to Section 3.23 for distribution on such Distribution Date.

      By 1:00 p.m. New York time on the Servicer Remittance Date, the Servicer
shall remit in immediately available funds to the Trustee for deposit in the
Certificate Account an amount equal to the aggregate amount of Advances, if any,
to be made in respect of the Mortgage Loans and REO Properties for the related
Distribution Date either (i) from its own funds or (ii) from the Custodial
Account, to the extent of funds held therein for future distribution (in which
case it will cause to be made an appropriate entry in the records of the
Custodial Account that amounts held for future distribution have been, as
permitted by this Section 4.03, used by the Servicer in discharge of any such
Advance) or (iii) in the form of any combination of (i) and (ii) aggregating the
total amount of Advances to be made by the Servicer with respect to the Mortgage
Loans and REO Properties. Any amounts held for future distribution and so used
or withdrawn by the Servicer as permitted in Section 3.11(a)(ii) shall be
appropriately reflected in the Servicer's records and replaced by the Servicer
by deposit in the Custodial Account on or before any future Servicer Remittance
Date to the extent that the Available Distribution Amount for the related
Distribution Date (determined without regard to Advances to be made on the
Servicer Remittance Date) shall be less than the total amount that would be
distributed to the Classes of Certificateholders pursuant to Section 4.01 on
such Distribution Date if such amounts held for future distributions had not
been so used to make Advances. The Trustee will provide notice to the Servicer
by telecopy by the close of business on the Business Day prior to the
Distribution Date in the event that the amount remitted by the Servicer to the
Trustee on such date is less than the amount required to be remitted by the
Servicer as set forth in the Remittance Report for the related Distribution
Date.

      (c)   The obligation of the Servicer to make such Advances is mandatory,
notwithstanding any other provision of this Agreement but subject to (d) below,
and, with respect to any Mortgage Loan or REO Property, shall continue until a
Final Recovery Determination in connection therewith or the removal thereof from
the Trust Fund pursuant to any applicable provision of this Agreement, except as
otherwise provided in this Section.

      (d)   Notwithstanding anything herein to the contrary, no Advance or
Servicing Advance shall be required to be made hereunder by the Servicer if such
Advance or Servicing Advance would, if made, constitute a Nonrecoverable Advance
or Nonrecoverable Servicing Advance, respectively. The determination by the
Servicer that it has made a Nonrecoverable Advance or a Nonrecoverable Servicing
Advance or that any proposed Advance or Servicing Advance, if made, would
constitute a Nonrecoverable Advance or Nonrecoverable Servicing Advance,
respectively, shall be evidenced by a certification of a Servicing Officer
delivered to the Depositor and the Trustee.

      SECTION 4.04 Allocation of Realized Losses. (a) Prior to each
Determination Date, the Servicer shall determine as to each Mortgage Loan and
REO Property: (i) the total amount of Realized Losses, if any, incurred in
connection with any Final Recovery Determinations made

                                       51

during the related Prepayment Period; (ii) whether and the extent to which such
Realized Losses constituted Bankruptcy Losses; and (iii) the respective portions
of such Realized Losses allocable to interest and allocable to principal. Prior
to each Determination Date, the Servicer shall also determine as to each
Mortgage Loan: (i) the total amount of Realized Losses, if any, incurred in
connection with any Deficient Valuations made during the related Prepayment
Period; and (ii) the total amount of Realized Losses, if any, incurred in
connection with Debt Service Reductions in respect of Monthly Payments due
during the related Due Period. The information described in the two preceding
sentences that is to be supplied by the Servicer shall be evidenced by an
Officers' Certificate delivered to the Trustee by the Servicer prior to the
Determination Date immediately following the end of (i) in the case of
Bankruptcy Losses allocable to interest, the Due Period during which any such
Realized Loss was incurred, and (ii) in the case of all other Realized Losses,
the Prepayment Period during which any such Realized Loss was incurred.

      (b)   All Realized Losses on the Mortgage Loans shall be allocated or
covered by the Trustee on each Distribution Date as follows: first, to the
Accrued Certificate Interest for the Class CE Certificates for the related
Interest Accrual Period; second, to the Class CE Certificates, until the
Certificate Principal Balance thereof has been reduced to zero; third, to the
Class M-10 Certificates, until the Certificate Principal Balance thereof has
been reduced to zero; fourth, to the Class M-9 Certificates, until the
Certificate Principal Balance thereof has been reduced to zero; fifth, to the
Class M-8 Certificates, until the Certificate Principal Balance thereof has been
reduced to zero; sixth, to the Class M-7 Certificates until the Certificate
Principal Balance thereof has been reduced to zero; seventh, to the Class M-6
Certificates until the Certificate Principal Balance thereof has been reduced to
zero; eighth, to the Class M-5 Certificates until the Certificate Principal

until the Certificate Principal Balance thereof has been reduced to zero; tenth,
to the Class M-3 Certificates until the Certificate Principal Balance thereof
has been reduced to zero; eleventh, to the Class M-2 Certificates, until the
Certificate Principal Balance thereof has been reduced to zero; twelfth, to the
Class M-1 Certificates, until the Certificate Principal Balance thereof has been
reduced to zero; and thirteenth, concurrently, to the Class A-1 Certificates,
Class A-2 Certificates, Class A-3 Certificates and Class A-4 Certificates on a
pro rata basis based on the Certificate Principal Balance of each such Class of
Certificates, until their respective Certificate Principal Balances have been
reduced to zero.

      All Realized Losses to be allocated to the Certificate Principal Balances
of all Classes on any Distribution Date shall be so allocated after the actual
distributions to be made on such date as provided above. All references above to
the Certificate Principal Balance of any Class of Certificates shall be to the
Certificate Principal Balance of such Class immediately prior to the relevant
Distribution Date, before reduction thereof by any Realized Losses, in each case
to be allocated to such Class of Certificates, on such Distribution Date.

      Any allocation of Realized Losses to a Class A Certificate or Mezzanine
Certificate on any Distribution Date shall be made by reducing the Certificate
Principal Balance thereof by the amount so allocated and any allocation of
Realized Losses to a Class CE Certificates shall be made by reducing the amount
otherwise payable in respect thereof pursuant to Section

                                       52

4.01(a)(4)(vi). No allocations of any Realized Losses shall be made to the
Certificate Principal Balances of the Class P Certificates.

      As used herein, an allocation of a Realized Loss on a "pro rata basis"
among two or more specified Classes of Certificates means an allocation on a pro
rata basis, among the various Classes so specified, to each such Class of
Certificates on the basis of their then outstanding Certificate Principal
Balances prior to giving effect to distributions to be made on such Distribution
Date. All Realized Losses and all other losses allocated to a Class of
Certificates hereunder will be allocated among the Certificates of such Class in
proportion to the Percentage Interests evidenced thereby.

      (c)   All Realized Losses on the Mortgage Loans shall be allocated by the
Trustee on each Distribution Date to the following REMIC I Regular Interests in
the specified percentages, as follows: first, to Uncertificated Interest payable

an aggregate amount equal to the REMIC I Interest Loss Allocation Amount, 98%
and 2%, respectively; second, to the Uncertificated Balances of the REMIC I
Regular Interest I-LTAA and REMIC I Regular Interest I-LTZZ up to an aggregate
amount equal to the REMIC I Principal Loss Allocation Amount, 98% and 2%,
respectively; third, to the Uncertificated Balances of REMIC I Regular Interest
I-LTAA, REMIC I Regular Interest I-LTM10 and REMIC I Regular Interest I-LTZZ,
98%, 1% and 1%, respectively, until the Uncertificated Balance of REMIC I
Regular Interest I-LTM10 has been reduced to zero; fourth, to the Uncertificated
Balances of REMIC I Regular Interest I-LTAA, REMIC I Regular Interest I-LTM9 and
REMIC I Regular Interest I-LTZZ, 98%, 1% and 1%, respectively, until the
Uncertificated Balance of REMIC I Regular Interest I-LTM9 has been reduced to

      SECTION 4.05 Compliance with Withholding Requirements. Notwithstanding any
other provision of this Agreement, the Trustee shall comply with all federal
withholding requirements respecting payments to Certificateholders of interest
or original issue discount that the Trustee reasonably believes are applicable
under the Code. The consent of Certificateholders shall not be required for such
withholding. In the event the Trustee does withhold any amount from interest or
original issue discount payments or advances thereof to any Certificateholder
pursuant to federal withholding requirements, the Trustee shall indicate the
amount withheld to such Certificateholders.

      SECTION 4.06 Exchange Commission; Additional Information. (a)
Notwithstanding anything herein to the contrary, the Depositor, and not the
Trustee, shall be responsible for executing each Form 10-K filed on behalf of
the Trust.

      Within 15 days after each Distribution Date, the Trustee shall, in
accordance with applicable law, prepare and file with the Commission via the
Electronic Data Gathering and Retrieval System ("EDGAR"), any Form 10-D (or
other comparable Form containing the same or comparable information or other
information mutually agreed upon), in the form and substance as required by the
Exchange Act, with a copy of the statement to the Certificateholders for such
Distribution Date as an exhibit thereto. Any necessary disclosure in addition to
the statement to the Certificateholders that is required to be included on Form
10-D ("Additional Form 10-D Disclosure") shall, pursuant to the paragraph
immediately below, be reported by the Seller, the Depositor, the Trustee, the
Trust, any servicer under Item 1108(a)(3) of Regulation AB, any originator under
Item 1110(b) of Regulation AB, any other party contemplated by Items 1100(d)(1),
1112(b), Item 1114(b)(2) or 115(b) of Regulation AB as identified to the Trustee
by the Depositor (together the "Reporting Parties"), any party so required under
and directed and approved by the Depositor, and the Trustee will have no duty or
liability for any failure hereunder to determine or prepare any Additional Form
10-D Disclosure absent such reporting, direction and approval.

      For so long as the Trust is subject to the reporting requirements of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), within 5
calendar days after the related Distribution Date, (i) the Reporting Parties
shall be required to provide to the Trustee and the Depositor, to the extent
known, in EDGAR-compatible form, or in such other form as otherwise agreed upon
by the Trustee and the Depositor and such party, the form and substance of the
Additional Form 10-D Disclosure applicable to such party, and (ii) the Depositor
will approve, as to form and substance, or disapprove, as the case may be, the
inclusion of the Additional Form 10-D Disclosure on Form 10-D. The Trustee has
no duty under this Agreement to monitor or enforce the performance by the
Reporting Parties of their duties under this paragraph or proactively solicit or
procure from such parties any Additional Form 10-D

                                       54

Disclosure information. The Depositor will be responsible for any reasonable
fees and expenses assessed or incurred by the Trustee in connection with
including any Additional Form 10-D Disclosure on Form 10-D pursuant to this
paragraph.

      After preparing the Form 10-D, the Trustee shall forward electronically a
draft copy of the Form 10-D to the Depositor for review. No later than 2
Business Days prior to the 15th calendar day after the related Distribution
Date, a senior officer of the Depositor shall sign the Form 10-D and return an
electronic or fax copy of such signed Form 10-D (with an original executed hard
copy to follow by overnight mail) to the Trustee. If a Form 10-D cannot be filed
on time or if a previously filed Form 10-D needs to be amended, the Trustee will
follow the procedures set forth in the second paragraph of Section 4.06(d).
Promptly (but no later than 1 Business Day) after filing with the Commission,
the Trustee will make available on its internet website a final executed copy of
each Form 10-D. The signing party at the Depositor can be contacted as described
in Section 13.05 hereto. The parties to this Agreement acknowledge that the
performance by the Trustee of its duties under this Section 4.06(a) related to
the timely preparation and filing of Form 10-D is contingent upon such parties
strictly observing all applicable deadlines in the performance of their duties
under this Section 4.06(a). The Trustee shall have no liability for any loss,
expense, damage, claim arising out of or with respect to any failure to properly
prepare and/or timely file such Form 10-D, where such failure results from the
Trustee's inability or failure to receive, on a timely basis, any information
from any other party hereto needed to prepare, arrange for execution or file
such Form 10-D, not resulting from its own negligence, bad faith or willful
misconduct.

      (b)   Within 90 days after the end of each fiscal year of the Trust or
such earlier date as may be required by the Exchange Act (the "10-K Filing
Deadline") (it being understood that the fiscal year for the Trust ends on
December 31st of each year), commencing in March 2007, the Trustee shall prepare
and file on behalf of the Trust a Form 10-K, in form and substance as required
by the Exchange Act. Each such Form 10-K shall include the following items, in
each case to the extent they have been delivered to the Trustee within the
applicable time frames set forth in this Agreement, (i) an annual compliance
statement for the Servicer and each Additional Servicer, as described under
Section 12.04, (ii)(A) the annual reports on assessment of compliance with
servicing criteria for the Servicer, each Additional Servicer and the Trustee,
as described under Sections 11.04 and 12.05, and (B) if the Servicer's, each
Additional Servicer's or the Trustee's report on assessment of compliance with
servicing criteria described under Sections 11.04 and 12.05 identifies any
material instance of noncompliance, disclosure identifying such instance of
noncompliance, or if the Servicer's, each Additional Servicer's or the Trustee's
report on assessment of compliance with servicing criteria described under
Sections 11.04 and 12.05 is not included as an exhibit to such Form 10-K,
disclosure that such report is not included and an explanation why such report
is not included, (iii)(A) the registered public accounting firm attestation
report for the Servicer, each Additional Servicer and the Trustee, as described
under Sections 11.04 and 12.05, and (B) if any registered public accounting firm
attestation report described under Sections 11.04 and 12.05 identifies any
material instance of noncompliance, disclosure identifying such instance of
noncompliance, or if any such registered public accounting firm attestation
report is not included as an exhibit to such Form 10-K, disclosure that such
report is not included and an explanation why such report is not included, and
(iv) a backup Sarbanes-Oxley certificate ("Backup Sarbanes Certification") as
described in

                                       55

Section 12.05 and substantially in the form of Exhibit I-1 hereto. In addition,
the Trustee shall sign a certification (in the form attached hereto as Exhibit
I-2) for the benefit of the Depositor and its officers, directors and Affiliates
regarding certain aspects of the Servicer's Backup Sarbanes Certification (the
"Trustee Certification") (provided, however, that the Trustee shall not
undertake an analysis of the accountant's report attached as an exhibit to Form
10-K). Any necessary disclosure that is required to be included on Form 10-K
("Additional Form 10-K Disclosure") shall, pursuant to the paragraph immediately
below, be reported by the Reporting Parties and directed and approved by the
Depositor, and the Trustee will have no duty or liability for any failure
hereunder to determine or prepare any Additional Form 10-K Disclosure absent
such reporting, direction and approval.

      For so long as the Trust is subject to the reporting requirements of the
Exchange Act, no later than March 10 (with a 5 calendar day cure period),
commencing in March 2007 (i) the Reporting Parties shall be required to provide
to the Trustee and the Depositor, to the extent known, in EDGAR-compatible form,
or in such other form as otherwise agreed upon by the Trustee and the Depositor
and such party, the form and substance of the Additional Form 10-K Disclosure
applicable to such party, and (ii) the Depositor will approve, as to form and
substance, or disapprove, as the case may be, the inclusion of the Additional
Form 10-K Disclosure on Form 10-K. The Trustee has no duty under this Agreement
to monitor or enforce the performance by the Reporting Parties of their duties
under this paragraph or proactively solicit or procure from such parties any
Additional Form 10-K Disclosure information. The Depositor will be responsible
for any reasonable fees and expenses assessed or incurred by the Trustee in
connection with including any Additional Form 10-K Disclosure on Form 10-K
pursuant to this paragraph.

      After preparing the Form 10-K, the Trustee shall forward electronically a
draft copy of the Form 10-K to the Depositor for review. No later than end of
business New York City time on the 4th Business Day prior to the 10-K Filing
Deadline, a senior officer of the Depositor shall sign the Form 10-K and related
Sarbanes Certification (as defined below) to be filed with the SEC, and return
an electronic or fax copy of such signed Form 10-K (with an original executed
hard copy to follow by overnight mail) to the Trustee. If a Form 10-K cannot be
filed on time or if a previously filed Form 10-K needs to be amended, the
Trustee will follow the procedures set forth in the second paragraph of Section
406(d). Promptly (but no later than 1 Business Day) after filing with the
Commission, the Trustee will make available on its internet website a final
executed copy of each Form 10-K. The signing party at the Depositor can be
contacted as described in Section 13.05. The parties to this Agreement
acknowledge that the performance by the Trustee of its duties under this Section
4.06(b) related to the timely preparation and filing of Form 10-K is contingent
upon such parties (and any Additional Servicer or Servicing Function
Participant) strictly observing all applicable deadlines in the performance of
their duties under this Section 4.06, Sections 11.04 and 12.05 and Section
12.04. The Trustee shall have no liability for any loss, expense, damage, claim
arising out of or with respect to any failure to properly prepare and/or timely
file such Form 10-K, where such failure results from the Trustee's inability or
failure to receive, on a timely basis, any information from any other party
hereto needed to prepare, arrange for execution or file such Form 10-K, not
resulting from its own negligence, bad faith or willful misconduct.

                                       56

      (c)   Within four (4) Business Days after the occurrence of an event
requiring disclosure on Form 8-K (each such event, a "Reportable Event"), and if
requested by the Depositor and to the extent it receives the Form 8-K Disclosure
Information described below, the Trustee shall prepare and file on behalf of the
Trust any Form 8-K, as required by the Exchange Act, provided that the Depositor
shall file the initial Form 8-K in connection with the issuance of the
Certificates. Any disclosure or information related to a Reportable Event or
that is otherwise required to be included on Form 8-K ("Form 8-K Disclosure
Information") shall, pursuant to the paragraph immediately below, be reported by
the Reporting Parties and directed and approved by the Depositor, and the
Trustee will have no duty or liability for any failure hereunder to determine or
prepare any Form 8-K Disclosure Information absent such reporting, direction and
approval.

      For so long as the Trust is subject to the reporting requirements of the
Exchange Act, no later than end of business on the 2nd Business Day after the
occurrence of a Reportable Event (i) the Reporting Parties hereto shall be
required to provide to the Trustee and the Depositor, to the extent known, in
EDGAR-compatible form, or in such other form as otherwise agreed upon by the
Trustee and the Depositor and such party, the form and substance of the Form 8-K
Disclosure Information applicable to such party, and (ii) the Depositor will
approve, as to form and substance, or disapprove, as the case may be, the
inclusion of the Form 8-K Disclosure Information on Form 8-K. The Trustee has no
duty under this Agreement to monitor or enforce the performance by the Reporting
Parties of their duties under this paragraph or proactively solicit or procure
from such parties any Form 8-K Disclosure Information. The Depositor will be
responsible for any reasonable fees and expenses assessed or incurred by the
Trustee in connection with including any Form 8-K Disclosure Information on Form
8-K pursuant to this paragraph.

      After preparing the Form 8-K, the Trustee shall forward electronically a
draft copy of the Form 8-K to the Depositor and the Servicer, if applicable, for
review. No later than Noon New York City time on the 4th Business Day after the
Reportable Event, a senior officer of the Depositor shall sign the Form 8-K and
return an electronic or fax copy of such signed Form 8-K (with an original
executed hard copy to follow by overnight mail) to the Trustee. If a Form 8-K
cannot be filed on time or if a previously filed Form 8-K needs to be amended,
the Trustee will follow the procedures set forth in the second paragraph of
Section 406(d). Promptly (but no later than 1 Business Day) after filing with
the Commission, the Trustee will, make available on its internet website a final
executed copy of each Form 8-K. The signing party at the Trustee can be
contacted as described in Section 13.05. The parties to this Agreement
acknowledge that the performance by the Trustee of its duties under this Section
4.06(c) related to the timely preparation and filing of Form 8-K is contingent
upon such parties strictly observing all applicable deadlines in the performance
of their duties under this Section 4.06(c). The Trustee shall have no liability
for any loss, expense, damage, claim arising out of or with respect to any
failure to properly prepare and/or timely file such Form 8-K, where such failure
results from the Trustee's inability or failure to receive, on a timely basis,
any information from any other party hereto needed to prepare, arrange for
execution or file such Form 8-K, not resulting from its own negligence, bad
faith or willful misconduct.

                                       57

      (d)   On or prior to January 30 of the first year in which the Trustee is
able to do so under applicable law, the Trustee shall prepare and file a Form 15
Suspension Notification relating to the automatic suspension of reporting in
respect of the Trust under the Exchange Act.

      In the event that the Trustee is unable to timely file with the Commission
all or any required portion of any Form 8-K, 10-D or 10-K required to be filed
by this Agreement because required disclosure information was either not
delivered to it or delivered to it after the delivery deadlines set forth in
this Agreement or for any other reason, the Trustee will promptly notify the
Depositor and the Servicer of such inability to make a timely filing with the
Commission. In the case of Form 10-D and 10-K, the Depositor, Servicer and
Trustee will cooperate to prepare and file a Form 12b-25 and a 10-DA and 10-KA
as applicable, pursuant to Rule 12b-25 of the Exchange Act. In the case of Form
8-K, the Trustee will, upon receipt of all required Form 8-K Disclosure
Information and upon the approval and direction of the Depositor, include such
disclosure information on the next succeeding Form 10-D to be filed for the
Trust. In the event that any previously filed Form 8-K, 10-D or 10-K needs to be
amended, the Trustee will notify the Depositor and the Servicer and such parties
agree to cooperate to prepare any necessary 8-KA, 10-DA or 10-KA. Any Form 15,
Form 12b-25 or any amendment to Form 8-K or 10-K shall be signed by a senior
officer of the Trustee and any amendment to Form 10-D shall be signed by a
senior officer of the Depositor. The Depositor and Servicer acknowledge that the
performance by the Trustee of its duties under this Section 4.06(d) related to
the timely preparation and filing of Form 15, a Form 12b-25 or any amendment to
Form 8-K, 10-D or 10-K is contingent upon the Servicer and the Depositor
performing their duties under this Section. The Trustee shall have no liability
for any loss, expense, damage, claim arising out of or with respect to any
failure to properly prepare and/or timely file any such Form 15, Form 12b-25 or
any amendments to Forms 8-K, 10-D or 10-K, where such failure results from the
Trustee's inability or failure to receive, on a timely basis, any information
from any other party hereto needed to prepare, arrange for execution or file
such Form 15, Form 12b-25 or any amendments to Forms 8-K, 10-D or 10-K, not
resulting from its own negligence, bad faith or willful misconduct.

      The Trustee shall have no responsibility to file any items other than
those specified in this Section 4.06; provided, however, the Trustee and the
Servicer will cooperate with the Depositor in connection with any additional
filings with respect to the Trust Fund as the Depositor deems necessary under
the Exchange Act.

                                   ARTICLE V

                                THE CERTIFICATES

      SECTION 5.01 The Certificates. (a) The Certificates in the aggregate will
represent the entire beneficial ownership interest in the Mortgage Loans and all
other assets included in REMIC I.

      The Certificates will be substantially in the forms annexed hereto as
Exhibits A-1 and A-17. The Certificates of each Class will be issuable in
registered form only, in denominations of

                                       58

authorized Percentage Interests as described in the definition thereof. Each
Certificate will share ratably in all rights of the related Class.

      Upon original issue, the Certificates shall be executed, authenticated and
delivered by the Trustee to or upon the written order of the Depositor. The
Certificates shall be executed by manual or facsimile signature on behalf of the
Trustee by an authorized signatory. Certificates bearing the manual or facsimile
signatures of individuals who were at any time the proper officers of the
Trustee shall bind the Trustee notwithstanding that such individuals or any of
them have ceased to hold such offices prior to the authentication and delivery
of such Certificates or did not hold such offices at the date of such
Certificates. No Certificate shall be entitled to any benefit under this
Agreement or be valid for any purpose, unless there appears on such Certificate
a certificate of authentication substantially in the form provided herein
executed by the Trustee by manual signature, and such certificate of
authentication shall be conclusive evidence, and the only evidence, that such
Certificate has been duly authenticated and delivered hereunder. All
Certificates shall be dated the date of their authentication.

      (b)   The Class A Certificates and the Mezzanine Certificates shall
initially be issued as one or more Certificates held by the Book-Entry Custodian
or, if appointed to hold such Certificates as provided below, the Depository and
registered in the name of the Depository or its nominee and, except as provided
below, registration of such Certificates may not be transferred by the Trustee
except to another Depository that agrees to hold such Certificates for the
respective Certificate Owners with Ownership Interests therein. The Certificate
Owners shall hold their respective Ownership Interests in and to such
Certificates through the book-entry facilities of the Depository and, except as
provided below, shall not be entitled to definitive, fully registered
Certificates ("Definitive Certificates") in respect of such Ownership Interests.
All transfers by Certificate Owners of their respective Ownership Interests in
the Book-Entry Certificates shall be made in accordance with the procedures
established by the Depository Participant or brokerage firm representing such
Certificate Owner. Each Depository Participant shall only transfer the Ownership
Interests in the Book-Entry Certificates of Certificate Owners it represents or
of brokerage firms for which it acts as agent in accordance with the
Depository's normal procedures. The Trustee is hereby initially appointed as the
Book-Entry Custodian and hereby agrees to act as such in accordance herewith and
in accordance with the agreement that it has with the Depository authorizing it
to act as such. The Book-Entry Custodian may, and, if it is no longer qualified
to act as such, the Book-Entry Custodian shall, appoint, by a written instrument
delivered to the Depositor, the Servicer, the Trustee and, if the Trustee is not
the Book-Entry Custodian, the Trustee, any other transfer agent (including the
Depository or any successor Depository) to act as Book-Entry Custodian under
such conditions as the predecessor Book-Entry Custodian and the Depository or
any successor Depository may prescribe, provided that the predecessor Book-Entry
Custodian shall not be relieved of any of its duties or responsibilities by
reason of any such appointment of other than the Depository. If the Trustee
resigns or is removed in accordance with the terms hereof, the successor Trustee
or, if it so elects, the Depository shall immediately succeed to its
predecessor's duties as Book-Entry Custodian. The Depositor shall have the right
to inspect, and to obtain copies of, any Certificates held as Book-Entry
Certificates by the Book-Entry Custodian.

                                       59

      The Trustee, the Servicer and the Depositor may for all purposes
(including the making of payments due on the respective Classes of Book-Entry
Certificates) deal with the Depository as the authorized representative of the
Certificate Owners with respect to the respective Classes of Book-Entry
Certificates for the purposes of exercising the rights of Certificateholders
hereunder. The rights of Certificate Owners with respect to the respective
Classes of Book-Entry Certificates shall be limited to those established by law
and agreements between such Certificate Owners and the Depository Participants
and brokerage firms representing such Certificate Owners. Multiple requests and
directions from, and votes of, the Depository as Holder of any Class of
Book-Entry Certificates with respect to any particular matter shall not be
deemed inconsistent if they are made with respect to different Certificate
Owners. The Trustee may establish a reasonable record date in connection with
solicitations of consents from or voting by Certificateholders and shall give
notice to the Depository of such record date.

      If (i)(A) the Depositor advises the Trustee in writing that the Depository
is no longer willing or able to properly discharge its responsibilities as
Depository, and (B) the Depositor is unable to locate a qualified successor or
(ii) after the occurrence of a Servicer Event of Default, Certificate Owners
representing in the aggregate not less than 66% of the Ownership Interests of
the Book-Entry Certificates advise the Trustee through the Depository, in
writing, that the continuation of a book-entry system through the Depository is
no longer in the best interests of the Certificate Owners, the Trustee shall
notify all Certificate Owners, through the Depository, of the occurrence of any
such event and of the availability of Definitive Certificates to Certificate
Owners requesting the same. Upon surrender to the Trustee of the Book-Entry
Certificates by the Book-Entry Custodian or the Depository, as applicable,
accompanied by registration instructions from the Depository for registration of
transfer, the Trustee shall cause the Definitive Certificates to be issued. Such
Definitive Certificates will be issued in minimum denominations of $25,000,
except that any beneficial ownership that was represented by a Book-Entry
Certificate in an amount less than $25,000 immediately prior to the issuance of
a Definitive Certificate shall be issued in a minimum denomination equal to the
amount represented by such Book-Entry Certificate. None of the Depositor, the
Servicer or the Trustee shall be liable for any delay in the delivery of such
instructions and may conclusively rely on, and shall be protected in relying on,
such instructions. Upon the issuance of Definitive Certificates all references
herein to obligations imposed upon or to be performed by the Depository shall be
deemed to be imposed upon and performed by the Trustee, to the extent applicable
with respect to such Definitive Certificates, and the Trustee shall recognize
the Holders of the Definitive Certificates as Certificateholders hereunder.

      SECTION 5.02 Registration of Transfer and Exchange of Certificates. (a)
The Trustee shall cause to be kept at one of the offices or agencies to be
appointed by the Trustee in accordance with the provisions of Section 8.11, a
Certificate Register for the Certificates in which, subject to such reasonable
regulations as it may prescribe, the Trustee shall provide for the registration
of Certificates and of transfers and exchanges of Certificates as herein
provided.

      (b)   No transfer of any Class M-10 Certificate, Class CE Certificate,
Class P Certificate or Residual Certificate (the "Private Certificates") shall
be made unless that transfer is made pursuant to an effective registration
statement under the Securities Act of 1933, as amended (the "1933 Act"), and
effective registration or qualification under applicable state

                                       60

securities laws, or is made in a transaction that does not require such
registration or qualification. In the event that such a transfer of a Private
Certificate is to be made without registration or qualification (other than in
connection with (i) the initial transfer of any such Certificate by the
Depositor to an Affiliate of the Depositor, (ii) the transfer of any such Class
CE or Class P Certificate to the issuer under the Indenture or the indenture
trustee under the Indenture or (iii) a transfer of any such Class CE or Class P
Certificate from the issuer under the Indenture or the indenture trustee under
the Indenture to the Depositor or an Affiliate of the Depositor), the Trustee
shall require receipt of: (i) if such transfer is purportedly being made in
reliance upon Rule 144A under the 1933 Act, written certifications from the
Certificateholder desiring to effect the transfer and from such
Certificateholder's prospective transferee, substantially in the forms attached
hereto as Exhibit F-1; and (ii) in all other cases, an Opinion of Counsel
satisfactory to it that such transfer may be made without such registration
(which Opinion of Counsel shall not be an expense of the Trust Fund or of the
Depositor, the Trustee, the Servicer in its capacity as such or any
Sub-Servicer), together with copies of the written certification(s) of the
Certificateholder desiring to effect the transfer and/or such
Certificateholder's prospective transferee upon which such Opinion of Counsel is
based, if any. None of the Depositor or the Trustee is obligated to register or
qualify any such Certificates under the 1933 Act or any other securities laws or
to take any action not otherwise required under this Agreement to permit the
transfer of such Certificates without registration or qualification. Any
Certificateholder desiring to effect the transfer of any such Certificate shall,
and does hereby agree to, indemnify the Trustee, the Depositor and the Servicer
against any liability that may result if the transfer is not so exempt or is not
made in accordance with such federal and state laws.

      Notwithstanding the foregoing, in the event of any such transfer of any
Ownership Interest in any Private Certificate that is a Book-Entry Certificate,
except with respect to the initial transfer of any such Ownership Interest by
the Depositor, such transfer shall be required to be made in reliance upon Rule
144A under the 1933 Act, and the transferee will be deemed to have made each of
the transferee representations and warranties set forth Exhibit F-1 hereto in
respect of such interest as if it was evidenced by a Definitive Certificate. The
Certificate Owner of any such Ownership Interest in any such Book-Entry
Certificate desiring to effect such transfer shall, and does hereby agree to,
indemnify the Trustee and the Depositor against any liability that may result if
the transfer is not so exempt or is not made in accordance with such federal and
state laws.

      Notwithstanding the foregoing, no certification or Opinion of Counsel
described in this Section 5.02(b) will be required in connection with the
transfer, on the Closing Date, of any Class R Certificate by the Depositor to an
"accredited investor" within the meaning of Rule 501(d) of the 1933 Act.

      (c)   (i)     No transfer of a Private Certificate (other than a Class
M-10 Certificate) or any interest therein shall be made to any Plan, any Person

acquiring such Private Certificates with "plan assets" of a Plan (within the
meaning of the Department of Labor regulation promulgated at 29 C. F. R. ss.
2510.3-101 ("Plan Assets")), as certified by such transferee in the form of
Exhibit G, unless the Trustee is provided with an Opinion of Counsel acceptable
to and in form and substance satisfactory to the Depositor, the Trustee and the
Servicer to the effect that the purchase and holding of such

                                       61

Private Certificates is permissible under applicable law, will not constitute or
result in any non-exempt prohibited transaction under Section 406 of ERISA or
Section 4975 of the Code (or comparable provisions of any subsequent enactments)
and will not subject the Depositor, the Servicer, the Trustee or the Trust Fund
to any obligation or liability (including obligations or liabilities under ERISA
or Section 4975 of the Code) in addition to those undertaken in this Agreement,
which Opinion of Counsel shall not be an expense of the Depositor, the Servicer,
the Trustee or the Trust Fund.

      (ii)  In the case of a Class A Certificate, Class M-1 Certificate, Class
M-2 Certificate, Class M-3 Certificate, Class M-4 Certificate, Class M-5
Certificate, Class M-6 Certificate, Class M-7 Certificate, Class M-8
Certificate, Class M-9 Certificate or Class M-10 Certificate, each beneficial
owner of such a Certificate or any interest therein shall be deemed to have
represented, by virtue of its acquisition or holding of such Certificate or any
interest therein, that either (A) it is not a Plan or a Plan investor, (B) it
has acquired and is holding such Certificate in reliance on the Underwriters'
Exemption, and that it understands that there are certain conditions to the
availability of the Underwriters' Exemption, including that such Certificate
must be rated, at the time of purchase, not lower than "BBB-" (or its
equivalent) by Fitch, S&P or Moody's and the Certificates are so rated, that it
is an accredited investor as defined in Rule 501(a)(1) of Regulation D of the
Securities Act of 1933, as amended, and that it will obtain a representation
from any transferee that such transferee is an accredited investor, or (C)(1) it
is an insurance company, (2) the source of funds used to acquire or hold such
Certificate or any interest therein is an "insurance company general account,"
as such term is defined in Prohibited Transaction Class Exemption ("PTCE")
95-60, and (3) the conditions in Sections I and III of PTCE 95-60 have been
satisfied.

      (iii) Neither a certification nor an Opinion of Counsel shall be required
in connection with (A) the initial transfer of any such Certificate by the
Depositor to an Affiliate of the Depositor, (B) the transfer of any such
Certificate to the issuer under the Indenture or the indenture trustee under the
Indenture or (C) a transfer of any such Certificate from the issuer under the
Indenture or the indenture trustee under the Indenture to the Depositor or an
Affiliate of the Depositor (in which case such transferee shall be deemed to
have represented that it is not purchasing with Plan Assets) and the Trustee
shall be entitled to conclusively rely upon a representation (which, upon the
request of the Trustee, shall be a written representation) from the Depositor of
the status of such transferee as an affiliate of the Depositor.

      (iv)  If any Certificate or any interest therein is acquired or held in
violation of the provisions of this Section 5.02(c), the next preceding
permitted beneficial owner will be treated as the beneficial owner of that
Certificate retroactive to the date of transfer to the purported beneficial
owner. Any purported beneficial owner whose acquisition or holding of any such
Certificate or any interest therein was effected in violation of the provisions
of this Section 5.02(c) shall indemnify and hold harmless the Depositor, the
Servicer, the Trustee and the Trust Fund from and against any and all
liabilities, claims, costs or expenses incurred by those parties as a result of
that acquisition or holding.

      (d)   (i) Each Person who has or who acquires any Ownership Interest in a
Residual Certificate shall be deemed by the acceptance or acquisition of such
Ownership Interest to have

                                       62

agreed to be bound by the following provisions and to have irrevocably
authorized the Trustee or its designee under clause (iii)(A) below to deliver
payments to a Person other than such Person and to negotiate the terms of any
mandatory sale under clause (iii)(B) below and to execute all instruments of
Transfer and to do all other things necessary in connection with any such sale.
The rights of each Person acquiring any Ownership Interest in a Residual
Certificate are expressly subject to the following provisions:

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

            (B)     In connection with any proposed Transfer of any Ownership
      Interest in a Residual Certificate, the Trustee shall require delivery to
      it, and shall not register the Transfer of any Residual Certificate until
      its receipt of, an affidavit and agreement (a "Transfer Affidavit and
      Agreement," in the form attached hereto as Exhibit F-2) from the proposed
      Transferee, in form and substance satisfactory to the Trustee,
      representing and warranting, among other things, that such Transferee is a
      Permitted Transferee, that it is not acquiring its Ownership Interest in
      the Residual Certificate that is the subject of the proposed Transfer as a
      nominee, trustee or agent for any Person that is not a Permitted
      Transferee, that for so long as it retains its Ownership Interest in a
      Residual Certificate, it will endeavor to remain a Permitted Transferee,
      and that it has reviewed the provisions of this Section 5.02(d) and agrees
      to be bound by them.

            (C)     Notwithstanding the delivery of a Transfer Affidavit and
      Agreement by a proposed Transferee under clause (B) above, if a
      Responsible Officer of the Trustee who is assigned to this transaction has
      actual knowledge that the proposed Transferee is not a Permitted
      Transferee, no Transfer of an Ownership Interest in a Residual Certificate
      to such proposed Transferee shall be effected.

            (D)     Each Person holding or acquiring any Ownership Interest in a
      Residual Certificate shall agree (x) to require a Transfer Affidavit and
      Agreement in the form attached hereto as Exhibit F-2 from any other Person
      to whom such Person attempts to transfer its Ownership Interest in a
      Residual Certificate and (y) not to transfer its Ownership Interest unless
      it provides a Transferor Affidavit (in the form attached hereto as Exhibit
      F-2) to the Trustee stating that, among other things, it has no actual
      knowledge that such other Person is not a Permitted Transferee.

            (E)     Each Person holding or acquiring an Ownership Interest in a
      Residual Certificate, by purchasing an Ownership Interest in such
      Certificate, agrees to give the Trustee written notice that it is a
      "pass-through interest holder" within the meaning of temporary Treasury
      regulation Section 1.67-3T(a)(2)(i)(A) immediately upon acquiring an
      Ownership Interest in a Residual Certificate, if it is, or is holding an
      Ownership Interest in a Residual Certificate on behalf of, a "pass-through
      interest holder."

            (ii)    The Trustee will register the Transfer of any Residual
      Certificate only if it shall have received the Transfer Affidavit and
      Agreement and all of such other

                                       63

      documents as shall have been reasonably required by the Trustee as a
      condition to such registration. In addition, no Transfer of a Residual
      Certificate shall be made unless the Trustee shall have received a
      representation letter from the Transferee of such Certificate to the
      effect that such Transferee is a Permitted Transferee.

            (iii)   (A)  If any purported Transferee shall become a Holder of a
      Residual Certificate in violation of the provisions of this Section
      5.02(d), then the last preceding Permitted Transferee shall be restored,
      to the extent permitted by law, to all rights as holder thereof
      retroactive to the date of registration of such Transfer of such Residual
      Certificate. The Trustee shall be under no liability to any Person for any
      registration of Transfer of a Residual Certificate that is in fact not
      permitted by this Section 5.02(d) or for making any payments due on such
      Certificate to the holder thereof or for taking any other action with
      respect to such holder under the provisions of this Agreement.

            (B)     If any purported Transferee shall become a holder of a
      Residual Certificate in violation of the restrictions in this Section
      5.02(d) and to the extent that the retroactive restoration of the rights
      of the holder of such Residual Certificate as described in clause (iii)(A)
      above shall be invalid, illegal or unenforceable, then the Trustee shall
      have the right, but not the obligation, without notice to the holder or
      any prior holder of such Residual Certificate, to sell such Residual
      Certificate to a purchaser selected by the Trustee on such terms as the
      Trustee may choose. Such purported Transferee shall promptly endorse and
      deliver each Residual Certificate in accordance with the instructions of
      the Trustee. Such purchaser may be the Trustee itself or any Affiliate of
      the Trustee. The proceeds of such sale, net of the commissions (which may
      include commissions payable to the Trustee or its Affiliates), expenses
      and taxes due, if any, will be remitted by the Trustee to such purported
      Transferee. The terms and conditions of any sale under this clause
      (iii)(B) shall be determined in the sole discretion of the Trustee, and
      the Trustee shall not be liable to any Person having an Ownership Interest
      in a Residual Certificate as a result of its exercise of such discretion.

            (iv)    The Trustee shall make available to the Internal Revenue
      Service and those Persons specified by the REMIC Provisions all
      information necessary to compute any tax imposed (A) as a result of the
      Transfer of an Ownership Interest in a Residual Certificate to any Person
      who is a Disqualified Organization, including the information described in
      Treasury regulations sections 1.860D-1(b)(5) and 1.860E-2(a)(5) with
      respect to the "excess inclusions" of such Residual Certificate and (B) as
      a result of any regulated investment company, real estate investment
      trust, common trust fund, partnership, trust estate or organization
      described in Section 1381 of the Code that holds an Ownership Interest in
      a Residual Certificate having as among its record holders at any time any
      Person which is a Disqualified Organization. Reasonable compensation for
      providing such information may be accepted by the Trustee.

            (v)     The provisions of this Section 5.02(d) set forth prior to
      this subsection (v) may be modified, added to or eliminated, provided that
      there shall have been delivered to the Trustee at the expense of the party
      seeking to modify, add to or eliminate any such provision the following:

                                       64

            (A)     written notification from each Rating Agency to the effect
      that the modification, addition to or elimination of such provisions will
      not cause such Rating Agency to downgrade its then-current ratings of any
      Class of Certificates; and

            (B)     an Opinion of Counsel, in form and substance satisfactory
      to the Trustee, to the effect that such modification of, addition to or
      elimination of such provisions will not cause any Trust REMIC to cease to
      qualify as a REMIC and will not cause any Trust REMIC to be subject to an
      entity-level tax caused by the Transfer of any Residual Certificate to a
      Person that is not a Permitted Transferee or a Person other than the
      prospective transferee to be subject to a REMIC-tax caused by the Transfer
      of a Residual Certificate to a Person that is not a Permitted Transferee.

      (e)   Subject to the preceding subsections, upon surrender for
registration of transfer of any Certificate at any office or agency of the
Trustee maintained for such purpose pursuant to Section 8.12, the Trustee shall
execute, authenticate and deliver, in the name of the designated Transferee or
Transferees, one or more new Certificates of the same Class of a like aggregate
Percentage Interest.

      (f)   At the option of the Holder thereof, any Certificate may be
exchanged for other Certificates of the same Class with authorized denominations
and a like aggregate Percentage Interest, upon surrender of such Certificate to
be exchanged at any office or agency of the Trustee maintained for such purpose
pursuant to Section 8.12. Whenever any Certificates are so surrendered for
exchange, the Trustee shall execute, authenticate and deliver, the Certificates
which the Certificateholder making the exchange is entitled to receive. Every
Certificate presented or surrendered for transfer or exchange shall (if so
required by the Trustee) be duly endorsed by, or be accompanied by a written
instrument of transfer in the form satisfactory to the Trustee duly executed by,
the Holder thereof or his attorney duly authorized in writing. In addition, with
respect to each Class R Certificate, the Holder thereof may exchange, in the
manner described above, such Class R Certificate for two separate Certificates,
each representing such Holder's respective Percentage Interest in the Class R-I
Interest and the Class R-II Interest, respectively, in each case that was
evidenced by the Class R Certificate being exchanged.

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

      (h)   All Certificates surrendered for transfer and exchange shall be
canceled and destroyed by the Trustee in accordance with its customary
procedures.

      SECTION 5.03 Mutilated, Destroyed, Lost or Stolen Certificates. If (i) any
mutilated Certificate is surrendered to the Trustee, or the Trustee receives
evidence to its satisfaction of the destruction, loss or theft of any
Certificate, and (ii) there is delivered to the Trustee such security or
indemnity as may be required by it to save it harmless, then, in the absence of
actual knowledge by the Trustee that such Certificate has been acquired by a
bona fide purchaser, the Trustee shall execute, authenticate and deliver in
exchange for or in lieu of any such mutilated,

                                       65

destroyed, lost or stolen Certificate, a new Certificate of the same Class and
of like denomination and Percentage Interest but bearing a number not
contemporaneously outstanding. Upon the issuance of any new Certificate under
this Section, the Trustee may require the payment of a sum sufficient to cover
any tax or other governmental charge that may be imposed in relation thereto and
any other expenses (including the fees and expenses of the Trustee) connected
therewith. Any replacement Certificate issued pursuant to this Section shall
constitute complete and indefeasible evidence of ownership in the applicable
REMIC created hereunder, as if originally issued, whether or not the lost,
stolen or destroyed Certificate shall be found at any time.

      SECTION 5.04 Persons Deemed Owners. Prior to due presentation of a
Certificate for registration of transfer, the Depositor, the Servicer, the
Trustee and any agent of any of them may treat the Person in whose name any
Certificate is registered as the owner of such Certificate for the purpose of
receiving distributions pursuant to Section 4.01 and for all other purposes
whatsoever, and none of the Depositor, the Servicer, the Trustee or any agent of
any of them shall be affected by notice to the contrary.

      SECTION 5.05 Certain Available Information. On or prior to the date of the
first sale of any Private Certificate to an Independent third party, the
Depositor shall provide to the Trustee a copy of any private placement
memorandum or other disclosure document used by the Depositor in connection with
the offer and sale of such Certificates. In addition, if any such private
placement memorandum or disclosure document is revised, amended or supplemented
at any time following the delivery thereof to the Trustee, the Depositor
promptly shall inform the Trustee of such event and shall deliver to the Trustee
a copy of the private placement memorandum or disclosure document, as revised,
amended or supplemented. The Trustee shall maintain at its Corporate Trust
Office and shall make available free of charge during normal business hours for
review by any Holder of a Certificate, a Certificate Owner or any Person
identified to the Trustee as a prospective transferee of a Certificate,
originals or copies of the following items: (i) in the case of a Holder, a
Certificate Owner or prospective transferee of a Private Certificate, the
related private placement memorandum or other disclosure document relating to
such Class of Certificates, in the form most recently provided to the Trustee;
and (ii) in all cases, (A) this Agreement and any amendments hereof entered into
pursuant to Section 13.01, (B) all monthly statements required to be delivered
to Certificateholders of the relevant Class pursuant to Section 4.02 since the
Closing Date, and all other notices, reports, statements and written
communications delivered to the Certificateholders of the relevant Class
pursuant to this Agreement since the Closing Date, (C) all certifications
delivered by a Responsible Officer of the Trustee since the Closing Date
pursuant to Section 10.01(h), (D) any and all Officers' Certificates delivered
to the Trustee by the Servicer since the Closing Date to evidence the Servicer's
determination that any Advance or Servicing Advance was, or if made, would be a
Nonrecoverable Advance or Nonrecoverable Servicing Advance, respectively, and
(E) any and all Officers' Certificates delivered to the Trustee by the Servicer
since the Closing Date pursuant to Section 4.04(a). Copies and mailing of any
and all of the foregoing items will be available from the Trustee upon request
at the expense of the Person requesting the same.

                                       66

                                   ARTICLE VI

                         THE DEPOSITOR AND THE SERVICER

      SECTION 6.01 Respective Liabilities of the Depositor and the Servicer. The
Depositor and the Servicer each shall be liable in accordance herewith only to
the extent of the obligations specifically imposed by this Agreement upon them
in their respective capacities as Depositor and Servicer and undertaken
hereunder by the Depositor and the Servicer herein.

      SECTION 6.02 Merger or Consolidation of the Depositor or the Servicer.
Subject to the following paragraph, the Depositor will keep in full effect its
existence, rights and franchises as a corporation under the laws of the
jurisdiction of its incorporation. Subject to the following paragraph, the
Servicer will keep in full effect its existence, rights and franchises as a
corporation under the laws of the jurisdiction of its incorporation. The
Depositor and the Servicer each will 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, the Certificates or any of the Mortgage Loans
and to perform its respective duties under this Agreement.

      The Depositor or the Servicer may be merged or consolidated with or into
any Person, or transfer all or substantially all of its assets to any Person, in
which case any Person resulting from any merger or consolidation to which the
Depositor or the Servicer shall be a party, or any Person succeeding to the
business of the Depositor or the Servicer, shall be the successor of the
Depositor or the Servicer, as the case may be, hereunder, without the execution
or filing of any paper or any further act on the part of any of the parties
hereto, anything herein to the contrary notwithstanding; provided, however, that
the successor or surviving Person to the Servicer shall be qualified to service
mortgage loans on behalf of Fannie Mae or Freddie Mac; and provided further that
the Rating Agencies' ratings of the Class A Certificates and the Mezzanine
Certificates in effect immediately prior to such merger or consolidation will
not be qualified, reduced or withdrawn as a result thereof (as evidenced by a
letter to such effect from the Rating Agencies).

      SECTION 6.03 Limitation on Liability of the Depositor, the Servicer and
Others. (a) The Servicer (except the Trustee if it is required to succeed the
Servicer hereunder) indemnifies and holds the each Certificateholder harmless
against any and all claims, losses, penalties, fines, forfeitures, reasonable
legal fees and related costs, judgments, and any other costs, fees and expenses
that any Certificateholder may sustain in any way related to the failure of the
Servicer to perform its duties and service the Mortgage Loans in compliance with
the terms of this Agreement. The Servicer shall immediately notify the Trustee
for further notice to each Certificateholder if a claim is made that may result
in such claims, losses, penalties, fines, forfeitures, legal fees or related
costs, judgments, or any other costs, fees and expenses, and the Servicer 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
Certificateholder in respect of such claim. The provisions of this Section 6.03
shall survive the termination of this Agreement and the payment of the
outstanding Certificates.

                                       67

      (b)   None of the Depositor, the Servicer or any of the directors,
officers, employees or agents of the Depositor or the Servicer shall be under
any liability to the Trustee, Trust Fund or the Certificateholders for any
action taken or for refraining from the taking of any action in good faith
pursuant to this Agreement, or for errors in judgment; provided, however, that
this provision shall not protect the Depositor, the Servicer or any such person
against any breach of warranties, representations or covenants made herein, or
against any specific liability imposed on the Servicer pursuant hereto, or
against any liability which would otherwise be imposed by reason of willful
misfeasance, bad faith or negligence in the performance of duties or by reason
of reckless disregard of obligations and duties hereunder. The Depositor, the
Servicer and any director, officer, employee or agent of the Depositor or the
Servicer may rely in good faith on any document of any kind which, prima facie,
is properly executed and submitted by any Person respecting any matters arising
hereunder. The Depositor, the Servicer and any director, officer, employee or
agent of the Depositor or the Servicer shall be indemnified by the Trust Fund
and held harmless against any loss, liability or expense (including reasonable
legal fees and disbursements of counsel) incurred on their part that may be
sustained in connection with, arising out of, or related to, any claim or legal
action (including any pending or threatened claim or legal action) relating to
this Agreement or the Certificates, other than any loss, liability or expense
relating to any specific Mortgage Loan or Mortgage Loans (except as any such
loss, liability or expense shall be otherwise reimbursable pursuant to this
Agreement) or any loss, liability or expense incurred by reason of willful
misfeasance, bad faith or negligence in the performance of duties hereunder or
by reason of reckless disregard of obligations and duties hereunder. Neither the
Depositor nor the Servicer shall be under any obligation to appear in, prosecute
or defend any legal action that is not incidental to its duties under this
Agreement and that in its opinion may involve it in any expense or liability;
provided, however, that the Depositor or the Servicer may in its discretion
undertake any such action which 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 Certificateholders hereunder. In such event, the legal expenses
and costs of such action and any liability resulting therefrom shall be
expenses, costs and liabilities of the Trust Fund, and the Depositor or the
Servicer shall be entitled to be reimbursed therefor from the Custodial Account
as and to the extent provided in Section 3.11, any such right of reimbursement
being prior to the rights of the Certificateholders to receive any amount in the
Custodial Account. Nothing in this Subsection 6.03(a) shall affect the
Servicer's obligation to supervise, or to take such actions as are necessary to
ensure, the servicing and administration of the Mortgage Loans pursuant to
Subsection 3.01(a).

      SECTION 6.04 Limitation on Resignation of the Servicer. (a) Subject to the
provisions of Section 7.01 and Section 6.02, the Servicer shall not resign from
the obligations and duties hereby imposed on it except (i) upon determination
that the performance of its obligations or 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 or its subsidiaries or
Affiliates, the other activities of the Servicer so causing such a conflict
being of a type and nature carried on by the Servicer or its subsidiaries or
Affiliates at the date of this Agreement or (ii) upon satisfaction of the
following conditions: (a) the Servicer has proposed a successor servicer to the
Trustee in writing and such proposed successor servicer is reasonably acceptable
to the Depositor and the Trustee and (b) each Rating Agency shall have delivered
a letter to the Trustee prior to the appointment of the successor servicer
stating that the proposed appointment of such

                                       68

successor servicer as Servicer hereunder will not result in the reduction or
withdrawal of the then current rating of the Certificates; provided, however,
that no such resignation by the Servicer shall become effective until such
successor servicer or, in the case of (i) above, the Trustee shall have assumed
the Servicer's responsibilities and obligations hereunder or the Trustee shall
have designated, a successor servicer in accordance with Section 7.02. Any such
resignation shall not relieve the Servicer of responsibility for any of the
obligations specified in Sections 7.01 and 7.02 as obligations that survive the
resignation or termination of the Servicer. Any such determination permitting
the resignation of the Servicer pursuant to clause (i) above shall be evidenced
by an Opinion of Counsel to such effect delivered to the Trustee.

      (b)   Except as expressly provided herein, the Servicer shall not assign
or transfer any of its rights, 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 Servicer hereunder. The foregoing prohibition on assignment shall not
prohibit the Servicer from designating a Sub-Servicer as payee of any
indemnification amount payable to the Servicer hereunder; provided, however,
that as provided in Section 3.06 hereof, no Sub-Servicer shall be a third-party
beneficiary hereunder and the parties hereto shall not be required to recognize
any Sub-Servicer as an indemnitee under this Agreement.

      SECTION 6.05 Rights of the Depositor in Respect of the Servicer. The
Servicer shall afford (and any Sub-Servicing Agreement shall provide that each
Sub-Servicer shall afford) the Depositor and the Trustee, upon reasonable
notice, during normal business hours, access to all records maintained by the
Servicer (and any such Sub-Servicer) in respect of the Servicer's rights and
obligations hereunder and access to officers of the Servicer (and those of any
such Sub-Servicer) responsible for such obligations. Upon request, the Servicer
shall furnish to the Depositor and the Trustee its (and any such Sub-Servicer's)
most recent financial statements and such other information relating to the
Servicer's capacity to perform its obligations under this Agreement as it
possesses (and that any such Sub-Servicer possesses). To the extent such
information is not otherwise available to the public, the Depositor and the
Trustee shall not disseminate any information obtained pursuant to the preceding
two sentences without the Servicer's written consent, except as required
pursuant to this Agreement or to the extent that it is appropriate to do so (i)
in working with legal counsel, auditors, taxing authorities or other
governmental agencies, (ii) pursuant to any law, rule, regulation, order,
judgment, writ, injunction or decree of any court or governmental authority
having jurisdiction over the Depositor and the Trustee or the Trust Fund, and in
any case, the Depositor or the Trustee, (iii) disclosure of any and all
information that is or becomes publicly known, or information obtained by the
Trustee from sources other than the Depositor or the Servicer, (iv) disclosure
as required pursuant to this Agreement or (v) disclosure of any and all
information(A) in any preliminary or final offering circular, registration
statement or contract or other document pertaining to the transactions
contemplated by the Agreement approved in advance by the Depositor or the
Servicer or (B) to any affiliate, independent or internal auditor, agent,
employee or attorney of the Trustee having a need to know the same, provided
that the Trustee advises such recipient of the confidential nature of the
information being disclosed, shall use its best efforts to assure the
confidentiality of any such disseminated non-public information. The Depositor
may, but is not obligated to, enforce the obligations of the Servicer under this
Agreement and may, but is not obligated to, perform, or cause a designee to
perform, any defaulted obligation of the Servicer

                                       69

under this Agreement or exercise the rights of the Servicer under this
Agreement; provided that the Servicer shall not be relieved of any of its
obligations under this Agreement by virtue of such performance by the Depositor
or its designee. The Depositor shall not have any responsibility or liability
for any action or failure to act by the Servicer and is not obligated to
supervise the performance of the Servicer under this Agreement or otherwise.

                                  ARTICLE VII

                                    DEFAULT

      SECTION 7.01 Servicer Events of Default. (a) "Servicer Event of Default,"
wherever used herein, means any one of the following events:

            (i)     any failure by the Servicer to remit to the Trustee for
      distribution to the Certificateholders any payment (other than an Advance
      required to be made from its own funds on any Servicer Remittance Date
      pursuant to Section 4.03) required to be made under the terms of the
      Certificates and this Agreement which continues unremedied for a period of
      5 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 Depositor or the Trustee (in which case notice shall be provided by
      telecopy), or to the Servicer, the Depositor and the Trustee by the
      Holders of Certificates entitled to at least 25% of the Voting Rights; or

            (ii)    any failure on the part of the Servicer duly to observe or
      perform in any material respect any other of the covenants or agreements
      on the part of the Servicer contained in this Agreement, or the breach by
      the Servicer of any representation and warranty contained in Section 2.05,
      which continues unremedied for a period of 30 days (or if such failure or
      breach cannot be remedied within 30 days, then such remedy shall have been
      commenced within 30 days and diligently pursued thereafter; provided,
      however, that in no event shall such failure or breach be allowed to exist
      for a period of greater than 90 days) or 15 days in the case of a failure
      to pay the premium for any insurance policy required to be maintained
      under this Agreement after the earlier of (i) the date on which written
      notice of such failure, requiring the same to be remedied, shall have been
      given to the Servicer by the Depositor or the Trustee, or to the Servicer,
      the Depositor and the Trustee by the Holders of Certificates entitled to
      at least 25% of the Voting Rights and (ii) actual knowledge of such
      failure by a Servicing Officer; or

            (iii)   a decree or order of a court or agency or supervisory
      authority having jurisdiction in the premises in an involuntary case under
      any present or future federal or state bankruptcy, insolvency or similar
      law or the appointment of a conservator or receiver or liquidator in any
      insolvency, readjustment of debt, marshalling of assets and liabilities or
      similar proceeding, 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 90
      days; or

                                       70

            (iv)    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 it or of or relating to all or substantially all of its
      property; or

            (v)     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 or reorganization statute, make an assignment
      for the benefit of its creditors, or voluntarily suspend payment of its
      obligations; or

            (vi)    any failure by the Servicer of the Servicer Termination
      Test; or

            (vii)   any failure of the Servicer to make any Advance on any
      Servicer Remittance Date required to be made from its own funds pursuant
      to Section 4.03 which continues unremedied until 12:00 p.m. New York time
      on the Business Day immediately following the Servicer Remittance Date.

      If a Servicer Event of Default described in clauses (i) through (vi) of
this Section shall occur, then, and in each and every such case, so long as such
Servicer Event of Default shall not have been remedied, the Trustee may, and at
the written direction of the Holders of Certificates entitled to at least 66% of
Voting Rights, the Trustee shall, by notice in writing to the Servicer and to
the Depositor, terminate all of the rights and obligations of the Servicer in
its capacity as Servicer under this Agreement, to the extent permitted by law,
in and to the Mortgage Loans and the proceeds thereof. If a Servicer Event of
Default described in clause (vii) hereof shall occur, the Trustee shall, by
notice in writing to the Servicer, terminate all of the rights and obligations
of the Servicer in its capacity as Servicer under this Agreement in and to the
Mortgage Loans and the proceeds thereof and the Trustee as successor Servicer,
or another successor servicer appointed in accordance with Section 7.02, shall
immediately make such Advance. On or after the receipt by the Servicer of such
written notice, all authority and power of the Servicer under this Agreement,
whether with respect to the Certificates (other than as a Holder of any
Certificate) or the Mortgage Loans or otherwise, shall pass to and be vested in
the Trustee pursuant to and under this Section, and, without limitation, the
Trustee is hereby authorized and empowered, as attorney-in-fact or otherwise, to
execute and deliver, on behalf of and at the expense of the Servicer, 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, provided, however, 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 the
Servicing obligations to the Trustee or other successor servicer. The Servicer
agrees promptly (and in any event no later than ten Business Days subsequent to
such notice) to provide the Trustee with all documents and records requested by
it to enable it to assume the Servicer's functions under this Agreement, and to
cooperate with the Trustee in effecting the termination of the Servicer's
responsibilities and rights under this Agreement, including, without limitation,
the transfer within one Business Day to the Trustee for administration by it of
all cash amounts which at the time shall be or should have been credited by the
Servicer to the Custodial Account held by or on behalf of the Servicer, the
Certificate

                                       71

Account or any REO Account or Servicing Account held by or on behalf of the
Servicer or thereafter be received with respect to the Mortgage Loans or any REO
Property serviced by the Servicer (provided, however, that the Servicer shall
continue to be entitled to receive all amounts accrued or owing to it under this
Agreement on or prior to the date of such termination, whether in respect of
Advances, Servicing Advances or otherwise, and shall continue to be entitled to
the benefits of Section 6.03, notwithstanding any such termination, with respect
to events occurring prior to such termination). For purposes of this Section
7.01, the Trustee shall not be deemed to have knowledge of a Servicer Event of
Default unless a Responsible Officer of the Trustee assigned to and working in
the Trustee's Corporate Trust Office has actual knowledge thereof or unless
written notice of any event which is in fact such a Servicer Event of Default is
received by the Trustee and such notice references the Certificates, the Trust
Fund or this Agreement.

      SECTION 7.02 Trustee to Act; Appointment of Successor. (a) (1) On and
after the time the Servicer receives a notice of termination in accordance with
Section 13.05 hereof, the Trustee, or such other person appointed by the Trustee
pursuant to this paragraph, shall separately assume and become the successor in
all respects to the Servicer in its capacity as Servicer under this Agreement
and the transactions set forth or provided for herein, and all the
responsibilities, duties and liabilities relating thereto and arising thereafter
shall be assumed by the Trustee (except for any representations or warranties of
the Servicer under this Agreement, the responsibilities, duties and liabilities
contained in Section 2.05 and the obligation to deposit amounts in respect of
losses pursuant to Section 3.12) by the terms and provisions hereof including,
without limitation, the Servicer's obligations to make Advances pursuant to
Section 4.03; provided, however, that if the Trustee is prohibited by law or
regulation from obligating itself to make advances regarding delinquent mortgage
loans, then the Trustee shall not be obligated to make Advances pursuant to
Section 4.03; and provided further, that any failure to perform such duties or
responsibilities caused by the Servicer's failure to provide information
required by Section 7.01 shall not be considered a default by the Trustee as
successor to the Servicer hereunder. As compensation therefor, the Trustee shall
be entitled to the Servicing Fee and all funds relating to the Mortgage Loans to
which the Servicer would have been entitled if it had continued to act
hereunder. Notwithstanding the above and subject to Section 7.02(a)(2) below,
the Trustee may, if it shall be unwilling to so act, or shall, if it is unable
to so act or if it is prohibited by law from making advances regarding
delinquent mortgage loans or if the Holders of Certificates entitled to at least
66% of the Voting Rights so request in writing to the Trustee promptly appoint
or petition a court of competent jurisdiction to appoint, a Fannie Mae or
Freddie Mac approved mortgage loan servicing institution acceptable to each
Rating Agency without qualification, withdrawal or downgrading of the ratings
then assigned to any of the Certificates and having a net worth of not less than
$10,000,000, as the successor to the Servicer under this Agreement in the
assumption of all or any part of the responsibilities, duties or liabilities of
the Servicer under this Agreement.

      All Servicing Transfer Costs shall be paid by the predecessor Servicer
upon presentation of reasonable documentation of such costs (provided, that if
the Trustee is the predecessor Servicer by reason of this Section 7.02, such
costs shall be paid by the Servicer preceding the Trustee as successor
servicer), and if such predecessor or initial Servicer, as applicable, defaults
in its obligation to pay such costs, such costs shall be paid by the successor
Servicer or the

                                       72

Trustee (in which case the successor Servicer or the Trustee, as applicable,
shall be entitled to reimbursement therefor from the assets of the Trust Fund).

            (2)     No appointment of a successor to the Servicer under this
      Agreement shall be effective until the assumption by the successor of all
      of the Servicer's responsibilities, duties and liabilities hereunder. In
      connection with such appointment and assumption described herein, the
      Trustee may make such arrangements for the compensation of such successor
      out of payments on Mortgage Loans as it and such successor shall agree;
      provided, however, that no such compensation shall be in excess of that
      permitted the Servicer as such hereunder. The Depositor, the Trustee and
      such successor shall take such action, consistent with this Agreement, as
      shall be necessary to effectuate any such succession. Pending appointment
      of a successor to the Servicer under this Agreement, the Trustee shall act
      in such capacity as hereinabove provided.

      SECTION 7.03 Notification to Certificateholders. (a) Upon any termination
of the Servicer pursuant to Section 7.01 above or any appointment of a successor
to the Servicer pursuant to Section 7.02 above, the Trustee shall give prompt
written notice thereof to Certificateholders at their respective addresses
appearing in the Certificate Register.

      (b)   Not later than the later of 60 days after the occurrence of any
event, which constitutes or which, with notice or lapse of time or both, would
constitute a Servicer Event of Default or five days after a Responsible Officer
of the Trustee becomes aware of the occurrence of such an event, the Trustee
shall transmit by mail to all Holders of Certificates notice of each such
occurrence, unless such default or Servicer Event of Default shall have been
cured or waived.

      SECTION 7.04 Waiver of Servicer Events of Default. Holders representing at
least 66% of the Voting Rights evidenced by all Classes of Certificates affected
by any default or Servicer Event of Default hereunder may waive such default or
Servicer Event of Default; provided, however, that a default or Servicer Event
of Default under clause (i) or (vii) of Section 7.01 may be waived only by all
of the Holders of the Regular Certificates. Upon any such waiver of a default or
Servicer Event of Default, such default or Servicer Event of Default shall cease
to exist and shall be deemed to have been remedied for every purpose hereunder.
No such waiver shall extend to any subsequent or other default or Servicer Event
of Default or impair any right consequent thereon except to the extent expressly
so waived.

                                  ARTICLE VIII

                             CONCERNING THE TRUSTEE

      SECTION 8.01 Duties of Trustee. (a) The Trustee, prior to the occurrence
of a Servicer Event of Default and after the curing of all Servicer Events of
Default which may have occurred, undertakes to perform such duties and only such
duties as are specifically set forth in this Agreement. During a Servicer Event
of Default (which has not been cured or waived), the Trustee shall exercise such
of the rights and powers vested in it by this Agreement, and use the same degree
of care and skill in their exercise as a prudent person would exercise or use
under

                                       73

the circumstances in the conduct of such person's own affairs. Any permissive
right of the Trustee enumerated in this Agreement shall not be construed as a
duty.

      (b)   The Trustee, upon receipt of all resolutions, certificates,
statements, opinions, reports, documents, orders or other instruments furnished
to the Trustee which are specifically required to be furnished pursuant to any
provision of this Agreement, shall examine them to determine whether they
conform on their face to the requirements of this Agreement. If any such
instrument is found not to conform on its face to the requirements of this
Agreement in a material manner, the Trustee shall take such action as it deems
appropriate to have the instrument corrected, and if the instrument is not
corrected to its satisfaction, will provide notice thereof to the
Certificateholders.

      (c)   No provision of this Agreement shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act or its own misconduct; provided, however, that:

            (i)     Prior to the occurrence of a Servicer Event of Default, and
      after the curing of all such Servicer Events of Default which may have
      occurred, the duties and obligations of the Trustee shall be determined
      solely by the express provisions of this Agreement, the Trustee shall not
      be liable except for the performance of such duties and obligations as are
      specifically set forth in this Agreement, no implied covenants or
      obligations shall be read into this Agreement against the Trustee and, in
      the absence of bad faith on the part of the Trustee, the Trustee may
      conclusively rely, as to the truth of the statements and the correctness
      of the opinions expressed therein, upon any certificates or opinions
      furnished to the Trustee that conform to the requirements of this
      Agreement;

            (ii)    The Trustee shall not be personally liable for an error of
      judgment made in good faith by a Responsible Officer or Responsible
      Officers of the Trustee unless it shall be proved that the Trustee was
      negligent in ascertaining the pertinent facts; and

            (iii)   The Trustee shall not be personally liable with respect
      to any action taken, suffered or omitted to be taken by it in good faith
      in accordance with the direction of the Holders of Certificates entitled
      to at least 25% of the Voting Rights relating to the time, method and
      place of conducting any proceeding for any remedy available to the Trustee
      or exercising any trust or power conferred upon it, under this Agreement.

      (d)   The Trustee shall timely pay, from its own funds, the amount of any
and all federal, state and local taxes imposed on the Trust Fund or its assets
or transactions including, without limitation, (A) "prohibited transaction"
penalty taxes as defined in Section 860F of the Code, if, when and as the same
shall be due and payable, (B) any tax on contributions to a Trust REMIC after
the Closing Date imposed by Section 860G(d) of the Code and (C) any tax on "net
income from foreclosure property" as defined in Section 860G(c) of the Code, but
only if such taxes arise out of a breach by the Trustee of its obligations
hereunder, which breach constitutes negligence or misconduct of the Trustee.

                                       74

      SECTION 8.02 Certain Matters Affecting the Trustee. (a) Except as
otherwise provided in Section 8.01:

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

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

            (iii)   The Trustee shall not be under any obligation to exercise
      any of the trusts or powers vested in it by this Agreement or to
      institute, conduct or defend any litigation hereunder or in relation
      hereto at the request, order or direction of any of the
      Certificateholders, pursuant to the provisions of this Agreement, unless
      such Certificateholders shall have offered to the Trustee security or
      indemnity reasonably satisfactory to it against the costs, expenses and
      liabilities which may be incurred therein or thereby; nothing contained
      herein shall, however, relieve the Trustee of the obligation, upon the
      occurrence of a Servicer Event of Default (which has not been cured or
      waived), to exercise such of the rights and powers vested in it by this
      Agreement, and to use the same degree of care and skill in their exercise
      as a prudent person would exercise or use under the circumstances in the
      conduct of such person's own affairs;

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

            (v)     Prior to the occurrence of a Servicer Event of Default
      hereunder and after the curing of all Servicer Events of Default which may
      have occurred, the Trustee shall not be bound to make any investigation
      into the facts or matters stated in any resolution, certificate,
      statement, instrument, opinion, report, notice, request, consent, order,
      approval, bond or other paper or document, unless requested in writing to
      do so by the Holders of Certificates entitled to at least 25% of the
      Voting Rights; provided, however, that if the payment within a reasonable
      time to the Trustee of the costs, expenses or liabilities likely to be
      incurred by it in the making of such investigation is, in the opinion of
      the Trustee not reasonably assured to the Trustee by such
      Certificateholders, the Trustee may require indemnity reasonably
      satisfactory to it against such expense or liability from such
      Certificateholders as a condition to taking any such action;

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

                                       75

      the Trustee shall not be responsible for any misconduct or negligence on
      the part of any agents, accountants or attorneys appointed with due care
      by it hereunder;

            (vii)   The Trustee shall have no obligation to invest and reinvest
      any cash held in the absence of timely and specific written investment
      direction from the Servicer or the Depositor. In no event shall the
      Trustee be liable for the selection of investments or for investment
      losses incurred thereon. The Trustee shall have no liability in respect of
      losses incurred as a result of the liquidation of any investment incurred
      as a result of the liquidation of any investment prior to its stated
      maturity or the failure of the Servicer or the Depositor to provide timely
      written investment direction; and

            (viii)  In order to comply with its duties under the USA Patriot Act
      of 2001, the Trustee shall obtain and verify certain information and
      documentation from the other parties to this Agreement including, but not
      limited to, each such party's name, address and other identifying
      information.

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

      SECTION 8.03 Trustee Not Liable for Certificates or Mortgage Loans. The
recitals contained herein and in the Certificates (other than the signature of
the Trustee, the authentication of the Certificate Registrar on the
Certificates, the acknowledgments of the Trustee contained in Article II and the
representations and warranties of the Trustee in Section 8.13) shall be taken as
the statements of the Depositor and the Trustee assumes no responsibility for
their correctness. The Trustee makes no representations or warranties as to the
validity or sufficiency of this Agreement (other than as specifically set forth
with respect to such party in Section 8.13) or of the Certificates (other than
the signature of the Trustee and authentication of the Certificate Registrar on
the Certificates) or of any Mortgage Loan or related document or of MERS or the
MERS(R) System. The Trustee shall not be accountable for the use or application
by the Depositor of any of the Certificates or of the proceeds of such
Certificates, or for the use or application of any funds paid to the Depositor
or the Servicer in respect of the Mortgage Loans or deposited in or withdrawn
from the Custodial Account by the Servicer, other than any funds held by or on
behalf of the Trustee in accordance with Section 3.10, subject to Section 8.01.

      SECTION 8.04 Trustee May Own Certificates. The Trustee in its individual
capacity or any other capacity may become the owner or pledgee of Certificates
with the same rights it would have if it were not Trustee.

      SECTION 8.05 Trustee's Fees and Expenses. (a) The Trustee shall withdraw
from the Certificate Account on each Distribution Date and pay to itself the
Trustee Fee. The Trustee, or any director, officer, employee or agent of the
Trustee shall be indemnified by the Trust Fund

                                       76

and held harmless against any loss, liability or expense (not including
expenses, disbursements and advances incurred or made by the Trustee including
the compensation and the expenses and disbursements of its agents and counsel,
in the ordinary course of the Trustee's performance in accordance with the
provisions of this Agreement) incurred by the Trustee in connection with any
Servicer Event of Default (not including expenses, disbursements and advances
incurred or made by the Trustee in its capacity as successor Servicer), default,
claim or legal action or any pending or threatened claim or legal action arising
out of or in connection with the acceptance or administration of its obligations
and duties under this Agreement or the Cap Contracts Agreement, other than any
loss, liability or expense (i) resulting from a breach of the Servicer's
obligations and duties under this Agreement (for which the Servicer indemnifies
pursuant to Sections 8.05(b) and 10.03(b)), (ii) for the expenses of preparing
and filing Tax Returns pursuant to Section 10.01(d) or (iii) any loss, liability
or expense incurred by reason of its willful misfeasance, bad faith or
negligence in the performance of its duties hereunder or by reason of reckless
disregard of its respective obligations and duties hereunder. Any amounts
payable to the Trustee, or any director, officer, employee or agent of the
Trustee in respect of the indemnification provided by this paragraph (a), or
pursuant to any other right of reimbursement from the Trust Fund that the
Trustee, or any director, officer, employee or agent of the Trustee, may have
hereunder in its capacity as such, may be withdrawn by the Trustee from the
Certificate Account at any time.

      (b)   The Servicer agrees to indemnify the Trustee from, and hold it
harmless against, any loss, liability or expense (including reasonable legal
fees and disbursements of counsel) resulting from a breach of the Servicer's
obligations and duties under this Agreement. Such indemnity shall survive the
termination or discharge of this Agreement and the resignation or removal of the
Trustee. Any payment hereunder made by the Servicer to the Trustee shall be from
the Servicer's own funds, without reimbursement from the Trust Fund therefor.

      The provisions of this Section 8.05 shall survive the termination of this
Agreement or the earlier resignation or removal of the Trustee.

      SECTION 8.06 Eligibility Requirements for Trustee. The Trustee hereunder
shall at all times be a corporation or an association (other than the Depositor,
the Seller, the Servicer or any Affiliate of the foregoing) organized and doing
business under the laws of any state or the United States of America, authorized
under such laws to exercise corporate trust powers, having a combined capital
and surplus of at least $50,000,000 and subject to supervision or examination by
federal or state authority. If such corporation or association publishes reports
of conditions at least annually, pursuant to law or to the requirements of the
aforesaid supervising or examining authority, then for the purposes of this
Section the combined capital and surplus of such corporation or association
shall be deemed to be its combined capital and surplus as set forth in its most
recent report of condition so published. Any successor trustee appointed
pursuant to Section 8.07 shall have a sufficient rating so as to maintain the
then-current ratings of the Certificates. In case at any time the Trustee shall
cease to be eligible in accordance with the provisions of this Section, the
Trustee shall resign immediately in the manner and with the effect specified in
Section 8.07.

                                       77

      SECTION 8.07 Resignation and Removal of the Trustee. The Trustee may at
any time resign and be discharged from the trust hereby created by giving
written notice thereof to the Depositor, the Servicer and the
Certificateholders. Upon receiving such notice of resignation of the Trustee,
the Depositor shall promptly appoint a successor trustee by written instrument,
in duplicate, one copy of which instrument shall be delivered to the resigning
Trustee and one copy to the successor trustee. A copy of such instrument shall
be delivered to the Certificateholders, the Trustee and the Servicer by the
Depositor. If no successor trustee shall have been so appointed and have
accepted appointment within 30 days after the giving of such notice of
resignation or removal, the Trustee may petition any court of competent
jurisdiction for the appointment of a successor trustee.

      If at any time the Trustee shall cease to be eligible in accordance with
the provisions of Section 8.06 and shall fail to resign after written request
therefor by the Depositor, or if at any time the Trustee shall become incapable
of acting, or shall be adjudged bankrupt or insolvent, or a receiver of the
Trustee or of its property shall be appointed, or any public officer shall take
charge or control of the Trustee or of its property or affairs for the purpose
of rehabilitation, conservation or liquidation, then the Depositor may remove
the Trustee and appoint a successor trustee by written instrument, in duplicate,
which instrument shall be delivered to the Trustee so removed and to the
successor trustee. A copy of such instrument shall be delivered to the
Certificateholders and the Servicer by the Depositor.

      The Holders of Certificates entitled to at least 66% of the Voting Rights
may at any time remove the Trustee and appoint a successor trustee by written
instrument or instruments, in triplicate, signed by such Holders or their
attorneys-in-fact duly authorized, one complete set of which instruments shall
be delivered to the Depositor, one complete set to the Trustee so removed and
one complete set to the successor so appointed. A copy of such instrument shall
be delivered to the Certificateholders and the Servicer by the Depositor.

      Any resignation or removal of the Trustee and appointment of a successor
trustee pursuant to any of the provisions of this Section shall not become
effective until acceptance of appointment by the successor trustee as provided
in Section 8.08. Any costs associated with removing and replacing the Trustee
shall be payable by the Trustee being removed or replaced if such Trustee is
being removed or replaced for cause.

      SECTION 8.08 Successor Trustee. Any successor trustee appointed as
provided in Section 8.07 shall execute, acknowledge and deliver to the Depositor
and to its predecessor trustee an instrument accepting such appointment
hereunder, and thereupon the resignation or removal of the predecessor trustee
shall become effective and such successor trustee without any further act, deed
or conveyance, shall become fully vested with all the rights, powers, duties and
obligations of its predecessor hereunder, with the like effect as if originally
named as trustee herein. The predecessor trustee shall deliver to the successor
trustee all Mortgage Files and related documents and statements, as well as all
moneys, held by it hereunder (other than any Mortgage Files at the time held by
a custodian, which custodian shall become the agent of any successor trustee
hereunder), and the Depositor and the predecessor trustee shall execute and
deliver such instruments and do such other things as may reasonably be required
for more fully

                                       78

and certainly vesting and confirming in the successor trustee all such rights,
powers, duties and obligations.

      No successor trustee shall accept appointment as provided in this Section
unless at the time of such acceptance such successor trustee shall be eligible
under the provisions of Section 8.06 and the appointment of such successor
trustee shall not result in a downgrading of any Class of Certificates by either
Rating Agency, as evidenced by a letter from each Rating Agency.

      Upon acceptance of appointment by a successor trustee as provided in this
Section, the Depositor shall mail notice of the succession of such trustee
hereunder to all Holders of Certificates at their addresses as shown in the
Certificate Register. If the Depositor fails to mail such notice within 10 days
after acceptance of appointment by the successor trustee, the successor trustee
shall cause such notice to be mailed at the expense of the Depositor.

      SECTION 8.09 Merger or Consolidation of Trustee. Any corporation or
association into which the Trustee may be merged or converted or with which it
may be consolidated or any corporation or association resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation or association succeeding to the business of the Trustee shall be
the successor of the Trustee hereunder, provided such corporation or association
shall be eligible under the provisions of Section 8.06, 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.

      SECTION 8.10 Appointment of Co-Trustee or Separate Trustee. (a)
Notwithstanding any other provisions hereof, at any time, for the purpose of
meeting any legal requirements of any jurisdiction in which any part of REMIC I
or property securing the same may at the time be located, the Servicer and the
Trustee acting jointly shall have the power and shall execute and deliver all
instruments to appoint one or more Persons approved by the Trustee to act as
co-trustee or co-trustees, jointly with the Trustee, or separate trustee or
separate trustees, of all or any part of REMIC I, and to vest in such Person or
Persons, in such capacity, such title to REMIC I, or any part thereof, and,
subject to the other provisions of this Section 8.10, such powers, duties,
obligations, rights and trusts as the Servicer and the Trustee may consider
necessary or desirable. Any such co-trustee or separate trustee shall be subject
to the written approval of the Servicer. If the Servicer shall not have joined
in such appointment within 15 days after the receipt by it of a request so to
do, or in case a Servicer Event of Default shall have occurred and be
continuing, the Trustee alone shall have the power to make such appointment. No
co-trustee or separate trustee hereunder shall be required to meet the terms of
eligibility as a successor trustee under Section 8.06 hereunder and no notice to
Holders of Certificates of the appointment of co-trustee(s) or separate
trustee(s) shall be required under Section 8.08 hereof. The Servicer shall be
responsible for the fees of any co-trustee or separate trustee appointed under
this Section 8.10.

      (b)   In the case of any appointment of a co-trustee or separate trustee
pursuant to this Section 8.10, all rights, powers, duties and obligations
conferred or imposed upon the Trustee shall be conferred or imposed upon and
exercised or performed by the Trustee and such separate trustee or co-trustee
jointly, except to the extent that under any law of any jurisdiction in which

                                       79

any particular act or acts are to be performed by the Trustee (whether as
Trustee hereunder or as successor to the Servicer hereunder), the Trustee shall
be incompetent or unqualified to perform such act or acts, in which event such
rights, powers, duties and obligations (including the holding of title to REMIC
I or any portion thereof in any such jurisdiction) shall be exercised and
performed by such separate trustee or co-trustee at the direction of the
Trustee.

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

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

      SECTION 8.11 Trustee to Execute and Cap Contract. The Depositor hereby
directs the Trustee to execute, deliver and perform its obligations under the
Cap Contracts on the Closing Date and thereafter on behalf of the Holders of the
Class A Certificates and the Mezzanine Certificates. The Depositor, the Servicer
and the Holders of the Class A Certificates and the Mezzanine Certificates by
their acceptance of such Certificates acknowledge and agree that the Trustee
shall execute, deliver and perform its obligations under the Cap Contracts and
shall do so solely in its capacity as Trustee of the Trust Fund and not in its
individual capacity.

      SECTION 8.12 Appointment of Office or Agency. The Trustee shall maintain
an office or agency in the United States where the Certificates may be
surrendered for registration of transfer or exchange, and presented for final
distribution. As of the Closing Date, the Trustee designates its Corporate Trust
Office in Minneapolis, Minnesota for such purposes. Notices and demands to or
upon the Trustee in respect of the Certificates and this Agreement may be
delivered at the Corporate Trust Office in Columbia, Maryland.

      SECTION 8.13 Representations and Warranties of the Trustee. The Trustee
hereby represents and warrants, solely as to itself, to the Servicer and the
Depositor, as of the Closing Date, that:

            (i)     It is a national banking association duly organized, validly
      existing and in good standing under the laws of the United States.

                                       80

            (ii)    The execution and delivery of this Agreement by it, and the
      performance and compliance with the terms of this Agreement by it, will
      not violate its charter or bylaws.

            (iii)   It has the full power and authority to enter into and
      consummate all transactions contemplated by this Agreement, has duly
      authorized the execution, delivery and performance of this Agreement, and
      has duly executed and delivered this Agreement.

            (iv)    This Agreement, assuming due authorization, execution and
      delivery by the other parties hereto, constitutes a valid, legal and
      binding obligation of it, enforceable against it in accordance with the
      terms hereof, subject to (A) applicable bankruptcy, insolvency,
      receivership, reorganization, moratorium and other laws affecting the
      enforcement of creditors' rights generally, and (B) general principles of
      equity, regardless of whether such enforcement is considered in a
      proceeding in equity or at law.

                                   ARTICLE IX

                                   TERMINATION

      SECTION 9.01  Termination Upon Repurchase or Liquidation of All Mortgage
Loans. (a) Subject to Section 9.02, the respective obligations and
responsibilities under this Agreement of the Depositor, the Servicer and the
Trustee (other than the obligations of the Servicer to the Trustee pursuant to
Section 8.05 and of the Servicer to make remittances to the Trustee and the
Trustee to make payments in respect of the REMIC I Regular Interests and the
Classes of Certificates as hereinafter set forth) shall terminate upon payment
to the Certificateholders and the deposit of all amounts held by or on behalf of
the Trustee and required hereunder to be so paid or deposited on the
Distribution Date coinciding with or following the earlier to occur of (i) the
purchase by the Terminator (as defined below) of all Mortgage Loans and each REO
Property remaining in REMIC I and (ii) the final payment or other liquidation
(or any advance with respect thereto) of the last Mortgage Loan or REO Property
remaining in REMIC I; provided, however, that in no event shall the trust
created hereby continue beyond the earlier of (a) the expiration of 21 years
from the death of the last survivor of the descendants of Joseph P. Kennedy, the
late ambassador of the United States to the Court of St. James, living on the
date hereof and (b) the latest possible Maturity Date. Subject to Section 3.10
hereof, the purchase by the Terminator of all Mortgage Loans and each REO
Property remaining in REMIC I shall be at a price equal to the greater of (i)
the Stated Principal Balance of the Mortgage Loans and the appraised value of
any REO Properties (such appraisal to be conducted by an Independent appraiser
mutually agreed upon by the Terminator and, to the extent that the Class A
Certificates or a Class of Mezzanine Certificates will not receive all amounts
owed to it as a result of the termination, the Trustee, in their reasonable
discretion) and (ii) the fair market value of the Mortgage Loans and the REO
Properties (as determined by the Terminator and, to the extent that the Class A
Certificates or a Class of Mezzanine Certificates will not receive all amounts
owed to it as a result of the termination, the Trustee (it being understood and
agreed that any determination by the Trustee shall be made solely in reliance on
an appraisal by an Independent appraiser as provided above)), as of the close of
business on the third Business Day next preceding the date upon which notice of
any such termination is furnished to the related

                                       81

Certificateholders pursuant to Section 9.01(c), in each case plus accrued and
unpaid interest thereon at the weighted average of the Mortgage Rates through
the end of the Due Period preceding the final Distribution Date plus
unreimbursed Servicing Advances, Advances, any unpaid Servicing Fees allocable
to such Mortgage Loans and REO Properties and any accrued and unpaid Net WAC
Rate Carryover Amounts (the "Termination Price"); provided, however, such option
may only be exercised if the Termination Price is sufficient to pay all interest
accrued on, as well as amounts necessary to retire the principal balance of,
each class of notes issued pursuant to the Indenture. If the determination of
the fair market value of the Mortgage Loans and REO Properties shall be required
to be made by the Terminator and an Independent appraiser as provided above, (A)
such appraisal shall be obtained at no expense to the Trustee and (B) the
Trustee may conclusively rely on, and shall be protected in relying on, such
appraisal.

      (b)   The majority Holder of the Class CE Certificates shall have the
right (the party exercising such right, the "Terminator") to purchase all of the
Mortgage Loans and each REO Property remaining in REMIC I pursuant to clause (i)
of the preceding paragraph in the manner set forth in Section 9.01(c) below if
the aggregate Stated Principal Balance of the Mortgage Loans and each REO
Property remaining in the Trust Fund at the time of such election is reduced to
less than 10% of the aggregate Stated Principal Balance of the Mortgage Loans as
of the Cut-off Date. By acceptance of a Residual Certificate, the Holders of the
Residual Certificates agree, in connection with any termination hereunder, to
assign and transfer any amounts in excess of par, and to the extent received in
respect of such termination, to pay any such amounts to the Holders of the Class
CE Certificates.

      (c)   Notice of the liquidation of the Certificates shall be given
promptly by the Trustee by letter to Certificateholders mailed (a) in the event
such notice is given in connection with the purchase of the Mortgage Loans and
each REO Property by the Terminator, not earlier than the 10th day and not later
than the 20th day of the month next preceding the month of the final
distribution on the related Certificates or (b) otherwise during the month of
such final distribution on or before the Determination Date in such month, in
each case specifying (i) the Distribution Date upon which the Trust Fund will
terminate and the final payment in respect of the REMIC I Regular Interests, as
applicable and the related Certificates will be made upon presentation and
surrender of the related Certificates at the office of the Trustee therein
designated, (ii) the amount of any such final payment, (iii) that no interest
shall accrue in respect of the REMIC I Regular Interests or the related
Certificates from and after the Interest Accrual Period relating to the final
Distribution Date therefor and (iv) that the Record Date otherwise applicable to
such Distribution Date is not applicable, payments being made only upon
presentation and surrender of the related Certificates at the office of the
Trustee. In the event such notice is given in connection with the purchase of
all of the Mortgage Loans and each REO Property remaining in REMIC I by the
Terminator, the Terminator shall deliver to the Trustee for deposit in the
Certificate Account, not later than the third Business Day preceding the date
for such final payment, an amount in immediately available funds equal to the
above-described purchase price. The Trustee shall remit to the Servicer from
such funds deposited in the Certificate Account (i) any amounts which the
Servicer would be permitted to withdraw and retain from the Custodial Account
pursuant to Section 3.11 and (ii) any other amounts otherwise payable by the
Trustee to the Servicer from amounts on deposit in the Certificate Account

                                       82

pursuant to the terms of this Agreement, in each case prior to making any final
distributions pursuant to Section 10.01(d) below. Upon certification to the
Trustee by the Terminator of the making of such final deposit, the Trustee shall
promptly release to the Terminator the Mortgage Files for the remaining Mortgage
Loans, and the Trustee shall execute all assignments, endorsements and other
instruments necessary to effectuate such transfer.

      Immediately following the deposit of funds in trust hereunder in respect
of the Certificates, the Trust Fund shall terminate.

      SECTION 9.02 Additional Termination Requirements. (a) In the event that
the Terminator purchases all the Mortgage Loans and each REO Property or the
final payment on or other liquidation of the last Mortgage Loan or REO Property
remaining in REMIC I pursuant to Section 9.01, the Trust Fund (or the applicable
Trust REMIC) shall be terminated in accordance with the following additional
requirements:

            (i)     The Trustee shall specify the first day in the 90-day
      liquidation period in a statement attached to each Trust REMIC's final Tax
      Return pursuant to Treasury regulation Section 1.860F-1 and shall satisfy
      all requirements of a qualified liquidation under Section 860F of the Code
      and any regulations thereunder, as evidenced by an Opinion of Counsel
      obtained at the expense of the Terminator;

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

            (iii)   At the time of the making of the final payment on the
      Certificates, the Trustee shall distribute or credit, or cause to be
      distributed or credited, to the Holders of the Residual Certificates in
      respect of the Class R-I Interest all cash on hand in the Trust Fund
      (other than cash retained to meet claims), and the Trust Fund shall
      terminate at that time.

      (b)   At the expense of the requesting Terminator (or, if the Trust Fund
is being terminated as a result of the occurrence of the event described in
clause (ii) of the first paragraph of Section 9.01, at the expense of the
Depositor without the right of reimbursement from the Trust Fund), the
Terminator shall prepare or cause to be prepared the documentation required in
connection with the adoption of a plan of liquidation of each Trust REMIC
pursuant to this Section 9.02.

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

                                       83

                                    ARTICLE X

                                REMIC PROVISIONS

      SECTION 10.01 REMIC Administration. (a) The Trustee shall elect to
treat each Trust REMIC as a REMIC under the Code and, if necessary, under
applicable state law. Each such election will be made by the Trustee on Form
1066 or other appropriate federal tax or information return or any appropriate
state return for the taxable year ending on the last day of the calendar year in
which the Certificates are issued. For the purposes of the REMIC election in
respect of REMIC I, the REMIC I Regular Interests shall be designated as the
Regular Interests in REMIC I and the Class R-I Interest shall be designated as
the sole class of Residual Interests in REMIC I. The Class A Certificates and
the Mezzanine Certificates shall be designated as the Regular Interests in REMIC
II and the Class R-II Interest shall be designated as the sole class of Residual
Interests in REMIC II. The Trustee shall not permit the creation of any
"interests" in any Trust REMIC (within the meaning of Section 860G of the Code)
other than the REMIC I Regular Interests and the interests represented by the
Certificates.

      (b)   The Closing Date is hereby designated as the "Startup Day" of each
Trust REMIC within the meaning of Section 860G(a)(9) of the Code.

      (c)   The Trustee shall be reimbursed for any and all expenses relating
to any tax audit of the Trust Fund (including, but not limited to, any
professional fees or any administrative or judicial proceedings with respect to
each Trust REMIC that involve the Internal Revenue Service or state tax
authorities), including the expense of obtaining any tax related Opinion of
Counsel required to be obtained hereunder. The Trustee, as agent for each Trust
REMIC's tax matters person shall (i) act on behalf of the Trust Fund in relation
to any tax matter or controversy involving any Trust REMIC and (ii) represent
the Trust Fund in any administrative or judicial proceeding relating to an
examination or audit by any governmental taxing authority with respect thereto.
The holder of the largest Percentage Interest of each Class of Residual
Certificates shall be designated, in the manner provided under Treasury
regulations section 1.860F-4(d) and Treasury regulations section
301.6231(a)(7)-1, as the tax matters person of the Trust REMICs created
hereunder. By their acceptance thereof, the holder of the largest Percentage
Interest of the Residual Certificates hereby agrees to irrevocably appoint the
Trustee or an Affiliate as its agent to perform all of the duties of the tax
matters person for the Trust Fund.

      (d)   The Trustee shall prepare, sign and file all of the Tax Returns
(including Form 8811, which must be filed within 30 days following the Closing
Date) in respect of each Trust REMIC created hereunder. The expenses of
preparing and filing such returns shall be borne by the Trustee without any
right of reimbursement therefor.

      (e)   The Trustee shall perform on behalf of each Trust REMIC all
reporting and other tax compliance duties that are the responsibility of such
REMIC under the Code, the REMIC Provisions or other compliance guidance issued
by the Internal Revenue Service or any state or local taxing authority. Among
its other duties, as required by the Code, the REMIC Provisions or other such
compliance guidance, the Trustee shall provide (i) to any Transferor of a
Residual Certificate such information as is necessary for the application of any
tax relating to the transfer

                                       84

of a Residual Certificate to any Person who is not a Permitted Transferee, (ii)
to the Certificateholders such information or reports as are required by the
Code or the REMIC Provisions including reports relating to interest, original
issue discount and market discount or premium (using the Prepayment Assumption
as required) and (iii) to the Internal Revenue Service the name, title, address
and telephone number of the person who will serve as the representative of each
Trust REMIC. The Depositor shall provide or cause to be provided to the Trustee,
within ten (10) days after the Closing Date, all information or data that the
Trustee reasonably determines to be relevant for tax purposes as to the
valuations and issue prices of the Certificates, including, without limitation,
the price, yield, prepayment assumption and projected cash flow of the
Certificates.

      (f)   The Trustee shall take such action and shall cause each Trust REMIC
created hereunder to take such action as shall be necessary to create or
maintain the status thereof as a REMIC under the REMIC Provisions. The Trustee
shall not take any action or cause the Trust Fund to take any action or fail to
take (or fail to cause to be taken) any action that, under the REMIC Provisions,
if taken or not taken, as the case may be, could (i) endanger the status of each
Trust REMIC as a REMIC or (ii) result in the imposition of a tax upon the Trust
Fund (including but not limited to the tax on prohibited transactions as defined
in Section 860F(a)(2) of the Code and the tax on contributions to a REMIC set
forth in Section 860G(d) of the Code) (either such event, an "Adverse REMIC
Event") unless the Trustee has received an Opinion of Counsel, addressed to the
Trustee (at the expense of the party seeking to take such action but in no event
at the expense of the Trustee) to the effect that the contemplated action will
not, with respect to any Trust REMIC, endanger such status or result in the
imposition of such a tax, nor shall the Servicer take or fail to take any action
(whether or not authorized hereunder) as to which the Trustee has advised it in
writing that it has received an Opinion of Counsel to the effect that an Adverse
REMIC Event could occur with respect to such action; provided that the Servicer
may conclusively rely on such Opinion of Counsel and shall incur no liability
for its action or failure to act in accordance with such Opinion of Counsel. In
addition, prior to taking any action with respect to any Trust REMIC or the
respective assets of each, or causing any Trust REMIC to take any action, which
is not contemplated under the terms of this Agreement, the Servicer will consult
with the Trustee or its designee, in writing, with respect to whether such
action could cause an Adverse REMIC Event to occur with respect to any Trust
REMIC and the Servicer shall not take any such action or cause any Trust REMIC
to take any such action as to which the Trustee has advised it in writing that
an Adverse REMIC Event could occur; provided that the Servicer may conclusively
rely on such writing and shall incur no liability for its action or failure to
act in accordance with such writing. The Trustee may consult with counsel to
make such written advice, and the cost of same shall be borne by the party
seeking to take the action not permitted by this Agreement, but in no event
shall such cost be an expense of the Trustee. At all times as may be required by
the Code, the Trustee will ensure that substantially all of the assets of REMIC
I will consist of "qualified mortgages" as defined in Section 860G(a)(3) of the
Code and "permitted investments" as defined in Section 860G(a)(5) of the Code,
to the extent such obligations are within the Trustee's control and not
otherwise inconsistent with the terms of this Agreement.

      (g)   In the event that any tax is imposed on "prohibited transactions"
of any Trust REMIC created hereunder as defined in Section 860F(a)(2) of the
Code, on the "net income from

                                       85

foreclosure property" of such REMIC as defined in Section 860G(c) of the Code,
on any contributions to any such REMIC after the Startup Day therefor pursuant
to Section 860G(d) of the Code, or any other tax is imposed by the Code or any
applicable provisions of state or local tax laws, such tax shall be charged (i)
to the Trustee pursuant to Section 10.03 hereof, if such tax arises out of or
results from a breach by the Trustee of any of its obligations under this
Article X, (ii) to the Servicer pursuant to Section 10.03 hereof, if such tax
arises out of or results from a breach by the Servicer of any of its obligations
under Article III or this Article X, or (iii) in all other cases, against
amounts on deposit in the Certificate Account and shall be paid by withdrawal
therefrom.

      (h)   On or before April 15 of each calendar year, commencing April 15,
2007, the Trustee shall deliver to each Rating Agency an Officer's Certificate
of the Trustee stating the Trustee's compliance with this Article X.

      (i)   The Trustee shall, for federal income tax purposes, maintain books
and records with respect to each Trust REMIC on a calendar year and on an
accrual basis.

      (j)   Following the Startup Day, neither the Servicer nor the Trustee
shall accept any contributions of assets to any Trust REMIC other than in
connection with any Qualified Substitute Mortgage Loan delivered in accordance
with Section 2.03 unless it shall have received an Opinion of Counsel to the
effect that the inclusion of such assets in the Trust Fund will not cause any
Trust REMIC to fail to qualify as a REMIC at any time that any Certificates are
outstanding or subject any Trust REMIC to any tax under the REMIC Provisions or
other applicable provisions of federal, state and local law or ordinances.

      (k)   Neither the Trustee nor the Servicer shall enter into any
arrangement by which any Trust REMIC will receive a fee or other compensation
for services nor knowingly permit any Trust REMIC to receive any income from
assets other than "qualified mortgages" as defined in Section 860G(a)(3) of the
Code or "permitted investments" as defined in Section 860G(a)(5) of the Code.

      SECTION 10.02 Prohibited Transactions and Activities. None of the
Depositor, the Servicer or the Trustee shall sell, dispose of or substitute for
any of the Mortgage Loans (except in connection with (i) the foreclosure of a
Mortgage Loan, including but not limited to, the acquisition or sale of a
Mortgaged Property acquired by deed in lieu of foreclosure, (ii) the bankruptcy
of REMIC I, (iii) the termination of REMIC I pursuant to Article IX of this
Agreement, (iv) a substitution pursuant to Article II of this Agreement or (v) a
purchase of Mortgage Loans pursuant to Article II or III of this Agreement), nor
acquire any assets for any Trust REMIC (other than REO Property acquired in
respect of a defaulted Mortgage Loan), nor sell or dispose of any investments in
the Custodial Account or the Certificate Account for gain, nor accept any
contributions to any Trust REMIC after the Closing Date (other than a Qualified
Substitute Mortgage Loan delivered in accordance with Section 2.03), unless it
has received an Opinion of Counsel, addressed to the Trustee (at the expense of
the party seeking to cause such sale, disposition, substitution, acquisition or
contribution but in no event at the expense of the Trustee) that such sale,
disposition, substitution, acquisition or contribution will not (a) affect
adversely the status of any Trust REMIC as a REMIC or (b) cause any Trust REMIC
to be

                                       86

subject to a tax on "prohibited transactions" or "contributions" pursuant to the
REMIC Provisions.

      SECTION 10.03 Servicer and Trustee Indemnification. (a) The Trustee
agrees to indemnify the Trust Fund, the Depositor and the Servicer for any taxes
and costs including, without limitation, any reasonable attorneys' fees imposed
on or incurred by the Trust Fund, the Depositor or the Servicer as a result of a
breach of the Trustee's covenants set forth in this Article X.

      (b)   The Servicer agrees to indemnify the Trust Fund, the Depositor and
the Trustee for any taxes and costs including, without limitation, any
reasonable attorneys' fees imposed on or incurred by the Trust Fund, the
Depositor or the Trustee, as a result of a breach of the Servicer's covenants

                                   ARTICLE XI

                      TRUSTEE COMPLIANCE WITH REGULATION AB

      SECTION 11.01 Intent of the Parties; Reasonableness. The Seller, the
Trustee, the Depositor and the Servicer acknowledge and agree that the purpose
of Article XI of this Agreement is to facilitate compliance by the Seller and
the Depositor with the provisions of Regulation AB and related rules and
regulations of the Commission. Neither the Seller nor the Depositor shall
exercise its right to request delivery of information or other performance under
these provisions other than in good faith, or for purposes other than compliance
with the Securities Act, the Exchange Act and the rules and regulations of the
Commission thereunder. Each of the Depositor, the Seller, the Servicer and the
Trustee acknowledges that interpretations of the requirements of Regulation AB
may change over time, whether due to interpretive guidance provided by the
Commission or its staff, consensus among participants in the asset-backed
securities markets, advice of counsel, or otherwise, and agrees to comply with
requests made by the Seller or the Depositor in good faith for delivery of
information under these provisions on the basis of evolving interpretations of
Regulation AB. Each of the Servicer and the Trustee shall cooperate fully with
the Seller to deliver to the Seller (including any of its assignees or
designees) and the Depositor, any and all statements, reports, certifications,
records and any other information necessary in the good faith determination of
the Seller or the Depositor to permit the Seller or the Depositor to comply with
the provisions of Regulation AB, together with such disclosures relating to the
Servicer, the Trustee and the Mortgage Loans, or the servicing of the Mortgage
Loans, reasonably believed by the Seller or the Depositor to be necessary in
order to effect such compliance.

      SECTION 11.02 Additional Representations and Warranties of the Trustee.
For so long as the Trust is subject to the reporting requirements of the
Exchange Act, the Trustee agrees that:

      (a)   The Trustee shall be deemed to represent to the Seller and to the
Depositor, as of the date hereof and the date on which information is provided
to the Seller or the Depositor under Sections 11.01, 11.02(b) or 11.03 that,
except as disclosed in writing to the Seller or the Depositor prior to such
date: (i) it is not aware and has not received notice that any default, early

                                       87

amortization or other performance triggering event has occurred as to any other
Securitization Transaction due to any act or failure to act of the Trustee; (ii)
it has not been terminated as trustee in a securitization of mortgage loans,
(iii) there are no aspects of it's financial condition that could have a
material adverse effect on its performance of its trustee obligations under this
Agreement or any other Securitization Transaction as to which it is the trustee;
(iv) there are no material legal or governmental proceedings pending (or known
to be contemplated) against it that would be material to Certificateholders; and
(v) there are no affiliations, relationships or transactions outside the
ordinary course of business relating to the Trustee, with respect to the
Depositor or any sponsor, issuing entity, servicer, trustee, originator,
significant obligor, enhancement or support provider or other material
transaction party (as such terms are used in Regulation AB) relating to the
Securitization Transaction contemplated by the Agreement (the "Transaction
Parties").

      (b)   If so requested by the Seller or the Depositor on any date
following the date on which information is first provided to the Seller or the
Depositor under Section 11.03, the Trustee shall, within five Business Days
following such request, confirm in writing the accuracy of the representations
and warranties set forth in paragraph (a) of this Section or, if any such
representation and warranty is not accurate as of the date of such request or
such confirmation, provide reasonably adequate disclosure of the pertinent
facts, in writing, to the requesting party.

      SECTION 11.03 Information to Be Provided by the Trustee.

      (a)   For so long as the Trust is subject to the reporting requirements
of the Exchange Act, for the purpose of satisfying the Depositor's and the
Seller's reporting obligation under the Exchange Act with respect to any class
of asset-backed securities, the Trustee shall provide to the Servicer and the
Seller a written description of (A) any litigation or governmental proceedings
pending against the Trustee as of the last day of the calendar month that would
be material to Certificateholders, and (B) any affiliations or relationships (as
described in Item 1119 of Regulation AB) that develop following the Closing Date
between the Trustee and any Transaction Party of the type described in Section
11.02(a)(iv) or 11.02(a)(v) as of the last day of each calendar year. Any
descriptions required with respect to legal proceedings, as well as updates to
previously provided descriptions, under this Section 11.03 shall be given no
later than five Business Days prior to the Determination Date following the
month in which the relevant event occurs, and any notices and descriptions
required with respect to affiliations, as well as updates to previously provided
descriptions, under this Section 11.03 shall be given no later than January 31
of the calendar year following the year in which the relevant event occurs. As
of the date the Depositor or the Trustee files each Report on Form 10-D and
Report on Form 10-K with respect to the Certificates, the Trustee will be deemed
to represent that any information previously provided under this Article XI is
materially correct and does not have any material omissions unless the Trustee
has provided an update to such information.

      (b)   In addition to such information as the Trustee is obligated to
provide pursuant to other provisions of this Agreement, if so requested by the
Servicer or the Seller in its reasonable good faith determination, the Trustee
shall provide such information regarding the performance or servicing of the
Mortgage Loans as is reasonably required to facilitate preparation of
distribution reports in accordance with Item 1121 of Regulation AB.

the immediately preceding calendar year, as required under Rules 13a-18 and
15d-18 of the Exchange Act and Item 1122 of Regulation AB. Such report shall be

Trustee and delivered pursuant to the preceding paragraph. 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;

      SECTION 11.05 Indemnification; Remedies. (a) The Trustee shall
indemnify the Seller, each affiliate of the Seller, the Depositor, the Servicer,
each broker dealer acting as underwriter, placement agent or initial purchaser,
each Person who controls any of such parties (within the meaning of Section 15
of the Securities Act and Section 20 of the Exchange Act); and the respective
present and former directors, officers, employees and agents of each of the
foregoing, and shall hold each of them harmless from and against any losses,
damages, penalties, fines, forfeitures, legal fees and expenses and related
costs, judgments, and any other costs, fees and expenses that any of them may
sustain arising out of or based upon:

            (i)     (A) any untrue statement of a material fact contained or

      report of a registered public accounting firm delivered by or on behalf of
      the Trustee or any Subcontractor of the Trustee pursuant to Section
      11.04(b), or (y) any information about the Trustee provided by it pursuant
      to Section 11.01, 11.02 or 11.03 (collectively, the "Trustee
      Information"), or (B) the omission or alleged omission to state in the
      Trustee Information a material fact required to be stated in the Trustee
      Information or necessary in order to make the statements therein, in the
      light of the circumstances under which they were made, not misleading;

            (ii)    any failure by the Trustee to deliver any information,
      report, certification, accountants' letter or other material when and as
      required under this Article XI; or

      SECTION 12.05 Report on Assessment of Compliance and Attestation. (a)
The Servicer shall, using best reasonable efforts on or before March 1, but in
no event later than March 15, commencing in 2007:

            (i)     deliver to the Seller, the Trustee and the Depositor a
      report (in form and substance reasonably satisfactory to the Seller and
      the Depositor) regarding the Servicer's assessment of compliance with the
      Servicing Criteria during the immediately preceding calendar year, as
      required under Rules 13a-18 and 15d-18 of the Exchange Act and Item 1122
      of Regulation AB. Such report shall be addressed to the Seller and the
      Depositor and signed by an authorized officer of the Servicer, and shall

      substantially in the form of Exhibit J-2 hereto delivered to the Seller
      concurrently with the execution of this Agreement;

            (ii)    deliver to the Seller, the Trustee and the Depositor a
      report of a registered public accounting firm reasonably acceptable to the
      Seller and the Depositor that attests to, and reports on, the assessment
      of compliance made by the Servicer and delivered pursuant to the preceding
      paragraph. 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; immediately upon receipt of such report, the Servicer shall, at its

      Agency. Copies of such statement shall be provided by the Trustee to any
      Certificateholder upon request, provided that such statement is delivered
      by the Servicer to the Trustee;

            (iii)   cause each Sub-Servicer, and each Subcontractor determined
      by the Servicer pursuant to Section 12.06(b) to be "participating in the
      servicing function" within the meaning of Item 1122 of Regulation AB, to
      deliver to the Seller, the Trustee and the Depositor an assessment of
      compliance and accountants' attestation as and when provided in paragraphs
      (a) and (b) of this Section; and

                                       91

            (iv)    if requested by the Seller or the Depositor not later than
      March 1 of the calendar year in which such certification is to be
      delivered, deliver the Backup Sarbanes Certification to the Seller, the

      Sarbanes-Oxley Act of 2002) on behalf of an asset-backed issuer with
      respect to the transactions contemplated by this Agreement.

The Servicer acknowledges that the parties identified in clause (a)(iv) above
may rely on the certification provided by the Servicer pursuant to such clause
in signing a Backup Sarbanes Certification and filing such with the Commission.
Neither the Seller nor the Depositor will request delivery of a certification
under clause (a)(iv) above unless the Depositor is required under the Exchange
Act to file an annual report on Form 10-K with respect to an issuing entity
whose asset pool includes Mortgage Loans.

      (b)   Each assessment of compliance provided by a Sub-Servicer pursuant
to Section 12.05(a)(i) shall address each of the Servicing Criteria specified on
a certification substantially in the form of Exhibit J-2 hereto delivered to the
Seller concurrently with the execution of this Agreement or, in the case of a
Sub-Servicer subsequently appointed as such, on or prior to the date of such
appointment. An assessment of compliance provided by a Subcontractor pursuant to
Section 12.05(a)(iii) need not address any elements of the Servicing Criteria
other than those specified by the Servicer pursuant to Section 12.06.

      SECTION 12.06 Use of Sub-Servicers and Subcontractors. The Servicer
shall not hire or otherwise utilize the services of any Sub-Servicer to fulfill
any of the obligations of the Servicer as servicer under this Agreement unless
the Servicer complies with the provisions of paragraph (a) of this Section. The
Servicer shall not hire or otherwise utilize the services of any Subcontractor,
and shall not permit any Sub-Servicer to hire or otherwise utilize the services
of any Subcontractor, to fulfill any of the obligations of the Servicer as
servicer under this Agreement unless the Servicer complies with the provisions
of paragraph (b) of this Section.

      (a)   It shall not be necessary for the Servicer to seek the consent of
the Seller or the Depositor to the utilization of any Sub-Servicer. The Servicer
shall cause any Sub-Servicer used by the Servicer (or by any Sub-Servicer) for
the benefit of the Seller and the Depositor to comply with the provisions of
this Section and with Sections 12.03(b), 12.04, 12.05 and 12.07 of this
Agreement to the same extent as if such Sub-Servicer were the Servicer, and to
provide the information required with respect to such Sub-Servicer under Section
12.03(a) of this Agreement. The Servicer shall be responsible for obtaining from
each Sub-Servicer and delivering to the Seller and the Depositor any servicer
compliance statement required to be delivered by such Sub-Servicer under Section
12.04, any assessment of compliance and attestation required to be delivered by
such Sub-Servicer under Section 12.05 and any certification required to be
delivered to the Person that will be responsible for signing the Sarbanes
Certification under Section 12.05 as and when required to be delivered.

      (b)   It shall not be necessary for the Servicer to seek the consent of
the Seller or the Depositor to the utilization of any Subcontractor. The
Servicer shall promptly upon request

                                       92

provide to the Seller and the Depositor (or any designee of the Depositor, such
as a master servicer or administrator) a written description (in form and
substance satisfactory to the Seller and the Depositor) of the role and function
of each Subcontractor utilized by the Servicer or any Sub-Servicer, 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
"participating in the servicing function" within the meaning of Item 1122 of
Regulation AB, the Servicer shall cause any such Subcontractor used by the
Servicer (or by any Sub-Servicer) for the benefit of the Seller and the
Depositor to comply with the provisions of Sections 12.05 and 12.07 of this
Agreement to the same extent as if such Subcontractor were the Servicer. The
Servicer shall be responsible for obtaining from each Subcontractor and
delivering to the Seller and the Depositor any assessment of compliance and
attestation required to be delivered by such Subcontractor under Section 12.05,
in each case as and when required to be delivered.

      SECTION 12.07 Indemnification; Remedies. (a) The Servicer shall
indemnify the Trustee, the Depositor, the Seller, each affiliate of the Seller,
and each of the following parties participating in the transactions contemplated
by this Agreement: each sponsor and issuing entity; each Person responsible for
the preparation, execution or filing of any report required to be filed with the
Commission with respect to such transactions, or for execution of a
certification pursuant to Rule 13a-14(d) or Rule 15d-14(d) under the Exchange
Act with respect to such transactions; each broker dealer acting as underwriter,
placement agent or initial purchaser, each Person who controls any of such
parties or the Depositor (within the meaning of Section 15 of the Securities Act
and Section 20 of the Exchange Act); and the respective present and former
directors, officers, employees and agents of each of the foregoing and of the
Depositor, and shall hold each of them harmless from and against any losses,
damages, penalties, fines, forfeitures, legal fees and expenses and related
costs, judgments, and any other costs, fees and expenses that any of them may
sustain arising out of or based upon:

            (i)     (A) any untrue statement of a material fact contained or
      alleged to be contained in any information, report, certification,
      accountants' letter or other material provided in written or electronic
      form under this Article XII by or on behalf of the Servicer, or provided
      under this Article XII by or on behalf of any Sub-Servicer, Subcontractor
      or Third-Party Originator (collectively, the "Servicer Information"), or
      (B) the omission or alleged omission to state in the Servicer Information
      a material fact required to be stated in the Servicer Information or
      necessary in order to make the statements therein, in the light of the
      circumstances under which they were made, not misleading; provided, by way
      of clarification, that clause (B) of this paragraph shall be construed
      solely by reference to the Servicer Information and not to any other
      information communicated in connection with a sale or purchase of
      securities, without regard to whether the Servicer Information or any
      portion thereof is presented together with or separately from such other
      information; or

                                       93

            (ii)    any failure by the Servicer, any Sub-Servicer, any
      Subcontractor or any Third-Party Originator to deliver any information,
      report, certification, accountants' letter or other material when and as
      required under this Article XII, including any failure by the Servicer to
      identify pursuant to Section 12.06(b) any Subcontractor "participating in
      the servicing function" within the meaning of Item 1122 of Regulation AB.

      In the case of any failure of performance described in clause (a)(ii) of
this Section, the Servicer shall promptly reimburse the Seller, the Depositor,
as applicable, and each Person responsible for the preparation, execution or
filing of any report required to be filed with the Commission with respect to
the transactions contemplated hereunder, or for execution of a certification
pursuant to Rule 13a-14(d) or Rule 15d-14(d) under the Exchange Act with respect
to the transactions contemplated by this Agreement, for all costs reasonably
incurred by each such party in order to obtain the information, report,
certification, accountants' letter or other material not delivered as required
by the Servicer, any Sub-Servicer, any Subcontractor or any Third-Party
Originator.

      (b)   (i) Any failure by the Servicer, any Sub-Servicer, any
Subcontractor or any Third-Party Originator to deliver any information, report,
certification, accountants' letter or other material when and as required under
this Article XII, shall, except as provided in clause (ii) of this paragraph,
immediately and automatically, without notice or grace period, constitute an
Event of Default with respect to the Servicer under this Agreement and shall
entitle the Depositor, in its sole discretion, to terminate the rights and
obligations of the Servicer as servicer under this Agreement without payment
(notwithstanding anything in this Agreement to the contrary) of any compensation
to the Servicer; provided that to the extent that any provision of this
Agreement expressly provides for the survival of certain rights or obligations
following termination of the Servicer as servicer, such provision shall be given
effect.

            (ii)    Any failure by the Servicer, any Sub-Servicer or any
      Subcontractor to deliver any information, report, certification or
      accountants' letter when and as required under Section 12.04 or 12.05,
      including (except as provided below) any failure by the Servicer to
      identify pursuant to Section 12.06(b) any Subcontractor "participating in
      the servicing function" within the meaning of Item 1122 of Regulation AB,
      which continues unremedied for ten calendar days after the date on which
      such information, report, certification or accountants' letter was
      required to be delivered shall constitute an Event of Default with respect
      to the Servicer under this Agreement, and shall entitle Depositor, as
      applicable, in its sole discretion to terminate the rights and obligations
      of the Servicer as servicer under this Agreement without payment
      (notwithstanding anything in this Agreement to the contrary) of any
      compensation to the Servicer; provided that to the extent that any
      provision of this Agreement expressly provides for the survival of certain
      rights or obligations following termination of the Servicer as servicer,
      such provision shall be given effect.

            Neither the Seller nor the Depositor shall be entitled to terminate
      the rights and obligations of the Servicer pursuant to this subparagraph
      (b)(ii) if a failure of the Servicer to identify a Subcontractor
      "participating in the servicing function" within the meaning of

                                       94

      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.

            (iii)   The Servicer shall promptly reimburse the Seller (or any
      designee of the Seller, such as a master servicer) and the Depositor, as
      applicable, for all reasonable expenses incurred by the Seller (or such
      designee) or the Depositor, as such are incurred, in connection with the
      termination of the Servicer as servicer and the transfer of servicing of
      the Mortgage Loans to a successor servicer. The provisions of this
      paragraph shall not limit whatever rights the Seller or the Depositor may
      have under other provisions of this Agreement or otherwise, whether in
      equity or at law, such as an action for damages, specific performance or
      injunctive relief.

                                  ARTICLE XIII

the then-current rating or the rating assigned to such Certificates as of the
Closing Date, as evidenced by a letter from each Rating Agency to such effect,
(v) to modify, eliminate or add to any of its provisions to such extent as shall
be necessary or desirable to maintain the qualification of any Trust REMIC
created hereunder as a Trust REMIC at all times that any Certificate is
outstanding or to avoid or minimize the risk of the imposition of any tax on the
Trust Fund pursuant to the Code that would be a claim against the Trust Fund,
provided that the Trustee has received an Opinion of Counsel to the effect that
(A) such action is necessary or desirable to maintain such qualification or to
avoid or minimize the risk of the imposition of any such tax and (B) such action
will not adversely affect in any material respect the interests of any
Certificateholder, (vi) such amendment is made to conform the terms of this
Agreement to the terms described in the Prospectus dated March 8, 2006 together
with the Prospectus Supplement dated March 10, 2006, or (vii) to make any other
provisions with respect to matters or questions arising under this Agreement
which shall not be inconsistent with the provisions of this Agreement, provided
that any such action pursuant to clauses (i), (ii), (iii) or (vii), as evidenced
by either (a) an Opinion of Counsel delivered to the Trustee adversely affect in
any material respect the interests of any Certificateholder or (b) written
notice to the Depositor, the Servicer and the Trustee from the Rating Agencies
that such action will not result in the reduction or withdrawal of the rating of
any outstanding Class of Certificates with respect to which it is a Rating
Agency). No amendment shall be deemed to adversely affect in any material
respect the interests of any Certificateholder who shall have consented thereto,
and no Opinion of Counsel

                                       95

or Rating Agency confirmation shall be required to address the effect of any
such amendment on any such consenting Certificateholder. Notwithstanding the
foregoing, neither an Opinion of Counsel nor written notice to the Depositor,
the Servicer and the Trustee from the Rating Agencies will be required in
connection with an amendment to the provisions of Section 4.06.

      This Agreement may also be amended from time to time by the Depositor, the
Servicer and the Trustee with the consent of the Holders of Certificates
entitled to at least 66% of the Voting Rights for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
this Agreement or of modifying in any manner the rights of the Holders of
Certificates; provided, however, that no such amendment shall (i) reduce in any
manner the amount of, or delay the timing of, payments received on Mortgage
Loans which are required to be distributed on any Certificate without the
consent of the Holder of such Certificate, (ii) adversely affect in any material
respect the interests of the Holders of any Class of Certificates (as evidenced
by either (a) an Opinion of Counsel delivered to the Trustee or (b) written
notice to the Depositor, the Servicer and the Trustee from the Rating Agencies
that such action will not result in the reduction or withdrawal of the rating of
any outstanding Class of Certificates with respect to which it is a Rating
Agency) in a manner, other than as described in (i) or (iii) modify the consents
required by the immediately preceding clauses (i) and (ii) without the consent
of the Holders of all Certificates then outstanding. Notwithstanding any other
provision of this Agreement, for purposes of the giving or withholding of
consents pursuant to this Section 13.01, Certificates registered in the name of
the Depositor or the Servicer or any Affiliate thereof shall be entitled to
Voting Rights with respect to matters affecting such Certificates.

      Notwithstanding any contrary provision of this Agreement, the Trustee
shall not consent to any amendment to this Agreement unless it shall have first
received an Opinion of Counsel to the effect that such amendment (i) will not
result in the imposition of any tax on any Trust REMIC pursuant to the REMIC
Provisions or cause any Trust REMIC to fail to qualify as a REMIC at any time
that any Certificates are outstanding and (ii) is authorized or permitted
hereunder.

      Promptly after the execution of any such amendment the Trustee shall
furnish a copy of such amendment to each Certificateholder.

      It shall not be necessary for the consent of Certificateholders under this
Section 13.01 to approve the particular form of any proposed amendment, but it
shall be sufficient if such consent shall approve the substance thereof. The
manner of obtaining such consents and of evidencing the authorization of the
execution thereof by Certificateholders shall be subject to such reasonable
regulations as the Trustee may prescribe.

      The cost of any Opinion of Counsel to be delivered pursuant to this
Section 13.01 shall be borne by the Person seeking the related amendment, but in
no event shall such Opinion of Counsel be an expense of the Trustee.

      The Trustee may, but shall not be obligated to enter into any amendment
pursuant to this Section that affects its rights, duties and immunities under
this Agreement or otherwise.

                                       96

      SECTION 13.02 Recordation of Agreement; Counterparts. To the extent
permitted by applicable law, this Agreement is subject to recordation in all
appropriate public offices for real property records in all of the counties or
other comparable jurisdictions in which any or all of the Mortgaged Properties
are situated, and in any other appropriate public recording office or elsewhere.
The Servicer shall effect such recordation at the Trust's expense upon the
request in writing of a Certificateholder, but only if such direction is
accompanied by an Opinion of Counsel (provided at the expense of the
Certificateholder requesting recordation) to the effect that such recordation
would materially and beneficially affect the interests of the Certificateholders
or is required by law.

      For the purpose of facilitating the recordation of this Agreement as
herein provided and for other purposes, this Agreement may be executed
simultaneously in any number of counterparts, each of which counterparts shall
be deemed to be an original, and such counterparts shall constitute but one and
the same instrument.

      SECTION 13.03 Limitation on Rights of Certificateholders. The death or
incapacity of any Certificateholder shall not operate to terminate this
Agreement or the Trust Fund, nor entitle such Certificateholder's legal
representative or heirs to claim an accounting or to take any action or commence
any proceeding in any court for a petition or winding up of the Trust Fund, or
otherwise affect the rights, obligations and liabilities of the parties hereto
or any of them.

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

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

                                       97

of this Section 13.03, each and every Certificateholder, the Trustee shall be
entitled to such relief as can be given either at law or in equity.

      SECTION 13.08 Article and Section References. All article and section
references used in this Agreement, unless otherwise provided, are to articles
and sections in this Agreement.

      SECTION 13.09 Grant of Security Interest. It is the express intent of
the parties hereto that the conveyance of the Mortgage Loans by the Depositor to
the Trustee, be, and be construed as, a sale of the Mortgage Loans by the
Depositor and not a pledge of the Mortgage Loans to secure a debt or other
obligation of the Depositor. However, in the event that, notwithstanding the
aforementioned intent of the parties, the Mortgage Loans are held to be property
of the Depositor, then, (a) it is the express intent of the parties that such
conveyance be deemed a pledge of the Mortgage Loans by the Depositor to the
Trustee to secure a debt or other obligation of the Depositor and (b) (1) this
Agreement shall also be deemed to be a security agreement within the meaning of
Articles 8 and 9 of the Uniform Commercial Code as in effect from time to time
in the State of New York; (2) the conveyance provided for in Section 2.01 hereof
shall be deemed to be a grant by the Depositor to the Trustee of a security
interest in all of the Depositor's right, title and interest in and to (i) such
Mortgage Loans and all amounts payable to the holders of the Mortgage Loans in
accordance with the terms thereof and all proceeds of the conversion, voluntary
or involuntary, of the foregoing into cash, instruments, securities or other
property and Prepayment Charges related thereto as from time to time are subject
to this Agreement, together with the Mortgage Files relating thereto, and
together with all collections thereon and proceeds thereof; (ii) any REO
Property, together with all collections thereon and

                                       99

proceeds thereof; (iii) the Depositor's rights with respect to the Mortgage
Loans under all insurance policies required to be maintained pursuant to this
Agreement and any proceeds thereof; (iv) the Depositor's rights under the
Mortgage Loan Purchase Agreement (including any security interest created
thereby); (v) the Custodial Account (other than any amounts representing any
Servicer Prepayment Charge Payment Amount), the Certificate Account (other than
any amounts representing any Servicer Prepayment Charge Payment Amount) and any
REO Account, and such assets that are deposited therein from time to time and
any investments thereof, together with any and all income, proceeds and payments
with respect thereto; (vi) the Net WAC Rate Carryover Reserve Account; and (vii)
the Depositor's rights under the Cap Contracts and all payments received under
the Cap Contracts; (3) the obligations secured by such security agreement shall
be deemed to be all of the Depositor's obligations under this Agreement,
including the obligation to provide to the Certificateholders the benefits of
this Agreement relating to the Mortgage Loans and the Trust Fund; and (4)
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 Trustee for the purpose
of perfecting such security interest under applicable law. Accordingly, the
Depositor hereby grants to the Trustee a security interest in the Mortgage Loans
and all other property described in clause (2) of the preceding sentence, for
the purpose of securing to the Trustee the performance by the Depositor of the
obligations described in clause (3) of the preceding sentence. Notwithstanding
the foregoing, the parties hereto intend the conveyance pursuant to Section 2.01
to be a true, absolute and unconditional sale of the Mortgage Loans and assets
constituting the Trust Fund by the Depositor to the Trustee.

      SECTION 13.10 Intention of Parties. It is the express intent of the
parties hereto that the conveyance of the Mortgage Notes, Mortgages, assignments
of Mortgages, title insurance policies and any modifications, extensions and/or
assumption agreements and private mortgage insurance policies relating to the
Mortgage Loans by the Seller to the Depositor, and by the Depositor to the
Trustee be, and be construed as, an absolute sale thereof to the Depositor or
the Trustee, as applicable. It is, further, not the intention of the parties
that such conveyance be deemed a pledge thereof by the Seller to the Depositor,
or by the Depositor to the Trustee. However, in the event that, notwithstanding
the intent of the parties, such assets are held to be the property of the Seller
or the Depositor, as applicable, or if for any other reason the Mortgage Loan
Purchase Agreement or this Agreement is held or deemed to create a security
interest in such assets, then (i) the Mortgage Loan Purchase Agreement and this
Agreement shall each be deemed to be a security agreement within the meaning of
the Uniform Commercial Code of the State of New York and (ii) the conveyance
provided for in the Mortgage Loan Purchase Agreement from the Seller to the
Depositor, and the conveyance provided for in this Agreement from the Depositor
to the Trustee, shall be deemed to be an assignment and a grant by the Seller or
the Depositor, as applicable, for the benefit of the Certificateholders, of a
security interest in all of the assets that constitute the Trust Fund, whether
now owned or hereafter acquired.

      The Depositor for the benefit of the Certificateholders shall, to the
extent consistent with this Agreement, take such actions as may be necessary to
ensure that, if this Agreement were deemed to create a security interest in the
assets of the Trust Fund, such security interest would

                                       100

be deemed to be a perfected security interest of first priority under applicable
law and will be maintained as such throughout the term of the Agreement.

      SECTION 13.11 Assignment. Notwithstanding anything to the contrary
contained herein, except as provided pursuant to Section 6.02, this Agreement
may not be assigned by the Servicer or the Depositor.

      SECTION 13.12 Inspection and Audit Rights. The Servicer agrees that, on
reasonable prior notice, it will permit any representative of the Depositor or
the Trustee during the Servicer's normal business hours, to examine all the
books of account, records, reports and other papers of the Servicer relating to
the Mortgage Loans, to make copies and extracts therefrom, to cause such books
to be audited by independent certified public accountants selected by the
Depositor or the Trustee and to discuss its affairs, finances and accounts
relating to such Mortgage Loans with its officers, employees and independent
public accountants (and by this provision the Servicer hereby authorizes such
accountants to discuss with such representative such affairs, finances and
accounts), all at such reasonable times and as often as may be reasonably
requested. Any out-of-pocket expense incident to the exercise by the Depositor
or the Trustee of any right under this Section 13.12 shall be borne by the party
requesting such inspection, subject to such party's right to reimbursement
hereunder (in the case of the Trustee, pursuant to Section 8.05 hereof).

      SECTION 13.13 Certificates Nonassessable and Fully Paid. It is the
intention of the Depositor that Certificateholders shall not be personally
liable for obligations of the Trust Fund, that the interests in the Trust Fund
represented by the Certificates shall be nonassessable for any reason
whatsoever, and that the Certificates, upon due authentication thereof by the
Trustee pursuant to this Agreement, are and shall be deemed fully paid.

      SECTION 13.14 Perfection Representations. The Perfection Representations
shall be a part of this Agreement for all purposes.

      SECTION 13.15 Notice to Holder of Class CE Certificate. Upon actual
knowledge by a Servicing Officer of an event which constitutes a Servicer Event
of Default under Section 7.01 of this Agreement or give rise to an indemnity
claim under Sections 3.25, 8.05(b), 10.03(b) or 14.02(g) of this Agreement, such
Servicing Officer shall promptly (but in no event later than two Business Days
following such knowledge) provide written notice to the Holder of the Class CE
Certificate of such event.

                                   ARTICLE XIV

                    RIGHTS OF THE CLASS CE CERTIFICATEHOLDER

      SECTION 14.01 Reports and Notices. (a) In connection with the
performance of its duties under this Agreement relating to, among other things,
the collection of Mortgage Loans, the Servicer shall provide to the Class CE
Certificateholder the following notices and reports in a timely manner and using
the same methodology and calculations used in its standard servicing reports to
the Trustee. The Servicer shall send all such notices and reports to the Class
CE

                                       101

Certificateholder in electronic format unless otherwise specified herein or
agreed to in writing by the Class CE Certificateholder.

            (i)     The Servicer shall, within ten Business Days after each
      Distribution Date, commencing in April 2006, provide to the Class CE
      Certificateholder a report of each Mortgage Loan in the Trust Fund,
      indicating the information contained in Exhibit L for the Due Period
      relating to such Distribution Date and to the extent such information is
      reasonably available to the Servicer.

            (ii)    Within ten Business Days after each Distribution Date
      commencing in April 2006, the Servicer shall provide the Class CE
      Certificateholder with a report listing each Mortgage Loan that has
      liquidated or paid off. Such report shall specify, if applicable and to
      the extent the information is reasonably available to the Servicer: (a)
      mortgage loan number; (b) outstanding Stated Principal Balance of the
      mortgage loan upon its liquidation; (c) Realized Loss or gain; (d)
      Liquidation Proceeds; (e) payoff date; (f) Prepayment Charges collected.

            (iii)   Where applicable, the Servicer shall provide the Class CE
      Certificateholder with copies of all primary mortgage insurance claims
      filed, as well as the actual amount paid in respect of any claim. Copies
      of any primary mortgage insurance claims will be provided to the Class CE
      Certificateholder within ten Business Days of their filing with the
      mortgage insurance company.

            (iv)    The Servicer shall provide the Class CE Certificateholder
      with a copy of the monthly reporting to the Trustee, and of any notice
      submitted to the Trustee regarding a loan modification. Such notice shall
      be provided to the Class CE Certificateholder simultaneous with its
      delivery to the Trustee.

            (v)     On a monthly basis, the Servicer shall provide the Class CE
      Certificateholder with a delinquency report detailing at a minimum the
      percentages of 30-day, 60-day and 90-day delinquencies in the Servicer's
      total portfolio that move into foreclosure and the percentage of
      foreclosed loans the Servicer's total portfolio that remain in
      foreclosure.

      (b)   The Servicer shall make its servicing personnel available during
their normal business hours to respond to reasonable inquiries, either orally or
in writing by facsimile transmission, express mail, or electronic mail,
transmitted by the Class CE Certificateholder in connection with any Mortgage
Loan identified in a report under subsection 14.01(a)(i) through (iv) which has
been given to the Class CE Certificateholder; provided that the Servicer shall
only be required to provide information that is reasonably accessible to its
servicing personnel.

      (c)   If reasonably requested by the Class CE Certificateholder, the
Servicer shall make available to the Class CE Certificateholder access to the
underwriting files for defaulted Mortgage Loans, in original, photocopied or
imaged form, to the extent such files have been provided to the Servicer. The
Class CE Certificateholder agrees to protect the confidentiality of the
documents and information contained in underwriting files from all parties other
than the

                                       102

Depositor and Trustee, and agrees not to remove, mark or destroy any of the
documents contained therein.

      (d)   With respect to all Mortgage Loans which are serviced at any time
by the Servicer through a Sub-Servicer which has been approved by the Class CE
Certificateholder pursuant to the next succeeding sentence, the Servicer shall
be entitled to rely for all purposes hereunder, including for purposes of
fulfilling its reporting obligations under this Section 14.01, on the accuracy
and completeness of any information provided to it by the applicable
subservicer. The Servicer shall not allow any Mortgage Loan to be serviced by a
Sub-Servicer without the prior written consent of such Sub-Servicer by the Class
CE Certificateholder.

      (e)   The Servicer shall permit the Class CE Certificateholder to conduct
an on-site review and evaluation of the Servicer's operations as they relate to
the Mortgage Loans no more than annually, unless circumstances warrant special
review. Such review and evaluation will be conducted upon at least 30 days
written notice to the Servicer by the Class CE Certificateholder, and shall be
conducted at the Class CE Certificateholder's expense. The review is intended to
benefit the Servicer, as well as to assist the Class CE Certificateholder in
adjusting its monitoring approach to fit the default procedures in place. The
Class CE Certificateholder will conduct such review and evaluation during normal
business hours and use its best efforts to cause the least practicable
interruption to the Servicer's business. During the course of the on-site
evaluation, the Servicer will make available to the Class CE Certificateholder
access to the Servicer's policies and procedures regarding the management and
liquidation of defaulted Mortgage Loans. The written findings of such review and
evaluation will be presented to the Servicer for review and comment. Other than
a comfort letter to the Depositor summarizing the review and evaluation of the
Servicer, the Class CE Certificateholder will not divulge the written findings
of such review to any party without the prior written consent of the Servicer.

      SECTION 14.02 Class CE Certificateholder's Directions With Respect to
Defaulted Mortgage Loans. (a) All parties to this Agreement acknowledge that the
Class CE Certificateholder's advice is made in the form of directions, and that
the Class CE Certificateholder has the right to direct the Servicer in
performing its duties under this Agreement. The Servicer must accept such
advice, subject to the duties of the Servicer set forth in this Agreement.

      (b)   The Class CE Certificateholder may provide the Servicer with advice
regarding the management of specific defaulted Mortgage Loans. Such advice may
be made in writing, in the form of electronic mail. The advice provided to the
Servicer may be based on observations made in conjunction with the data provided
pursuant to the Section 14.01 of this Agreement, or in conjunction with the
Class CE Certificateholder's periodic review of the Servicer's operations. The
advice may include comparable analysis of the performance of the Mortgage Loans
in the Trust Fund with similar mortgage loans serviced by other mortgage loan
servicers. Such advice also may take the form of benchmark comparisons that
identify and interpret the Servicer's strengths and weaknesses relative to
similar, unidentified servicers in the industry.

      (c)   In all cases where the Class CE Certificateholder makes directions
to the Servicer, the Class CE Certificateholder will protect the confidentiality
of the Servicer and other servicers

                                       103

in the industry whose work is monitored by the Class CE Certificateholder. Under
no circumstances will the Class CE Certificateholder divulge any materials
confidential of the Servicer, whether a party to this Agreement or not, or the
details of any Servicer's proprietary system or approaches.

      (d)   All advice offered to the Servicer by the Class CE Certificateholder
will be kept confidential by the Class CE Certificateholder, except as disclosed
as a finding in the Class CE Certificateholder's review and evaluation of the
Servicer, as discussed in Section 13.01(e), or in reports to the Depositor.

      (e)   The Servicer's obligations under this Article XIV shall terminate
upon the termination of the Trust Fund pursuant to Section 9.01.

      (f)   Neither the Servicer nor the Class CE Certificateholder nor any of
their respective directors, officers, employees or agents shall be under any
liability for any action taken or for refraining from the taking of any action
in good faith pursuant to this Article XIV or for errors in judgment; provided,
however, that this provision shall not protect the Servicer or the Class CE
Certificateholder or any such Person against any liability which would otherwise
be imposed by reason of willful malfeasance or bad faith. The Servicer and the
Class CE Certificateholder and any director, officer, employee or agent thereof
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.

      (g)   The Servicer or the Class CE Certificateholder, as applicable,
("Indemnitor") shall indemnify, defend and hold harmless the other
("Indemnitee") and its officers, directors, agents and employees from and
against all claims, losses, expenses, fees (including attorneys' and expert
witnesses' fees), costs and judgments involving the rights and obligations of
this Article XIV that may be asserted against Indemnitee (a) that result from
the acts or omissions of the Indemnitor (including, without limitation, any
advice or directions provided pursuant to this Section 14.02), or (b) result
from third party claims of intellectual property infringement.

      (h)   The Class CE Certificateholder agrees that all information supplied
by or on behalf of the Servicer shall be used by the Class CE Certificateholder
only for the benefit of the Certificateholders of the Trust Fund.
Notwithstanding anything to the contrary in this Agreement, the Class CE
Certificateholder shall be entitled to retain all records or other information
supplied to Class CE Certificateholder pursuant to this Agreement.

                              DEFINITIONS AND USAGE

      The following rules of construction and usage shall be applicable to any
agreement or instrument that is governed by this Appendix:

      (a)   All terms defined in this Appendix shall have the defined meanings
when used in any agreement or instrument governed hereby and in any certificate
or other document made or delivered pursuant thereto unless otherwise defined
therein.

      (b)   As used herein, in any agreement or instrument governed hereby and
in any certificate or other document made or delivered pursuant thereto,
accounting terms not defined in this Appendix or in any such agreement,

them under generally accepted accounting principles as in effect on the date of
such agreement or instrument. To the extent that the definitions of accounting
terms in this Appendix or in any such agreement, instrument, certificate or

accepted accounting principles, the definitions contained in this Appendix or in
any such instrument, certificate or other document shall control.

      The words "hereof," "herein," "hereunder" and words of similar import when
used in an agreement or instrument refer to such agreement or instrument as a
whole and not to any particular provision or subdivision thereof; references in
an agreement or instrument to "Article," "Section" or another subdivision or to
an attachment are, unless the context otherwise requires, to an article, section
or subdivision of or an attachment to such agreement or instrument; and the term
"including" and its variations means "including without limitation."

      The definitions contained in this Appendix are equally applicable to both
the singular and plural forms of such terms and to the masculine as well as to
the feminine and neuter genders of such terms.

      Any agreement, instrument or statute defined or referred to below or in
any agreement or instrument that is governed by this Appendix means such

supplemented, including (in the case of agreements or instruments) by waiver or
consent and (in the case of statutes) by succession of comparable successor
statutes and includes (in the case of agreements or instruments) references to
all attachments thereto and instruments incorporated therein. References to a

exchange herefor or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain limited circumstances, without the consent of the Holders of any of the
Certificates.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices or agencies appointed by the Trustee as provided in the

shall be deemed to have represented, by virtue of its acquisition or holding of
such Certificate or any interest therein, that either (A) it is not an "employee
benefit plan" as defined in Section 3(3) of the Employee Retirement Income
Security Act of 1974, as amended ("ERISA"), that is subject to Title I of ERISA,
any "plan" as defined in Section 4975(e)(1) of the Internal Revenue Code of
1986, as amended (the "Code"), that is subject to Section 4975 of the Code or
any entity deemed to hold plan assets of any of the foregoing, (B) it has
acquired and is holding this Certificate in reliance on the underwriters'
exemption, and that it understands that there are certain conditions to the
availability of the underwriters' exemption, including that this Certificate
must be rated, at

                                      A-1-3

the time of purchase, not lower than "BBB-" (or its equivalent) by Fitch, S&P or
Moody's and the Certificate is so rated, that it is an accredited investor as
defined in Rule 501(a)(1) of Regulation D of the Securities Act of 1933, as
amended, and that it will obtain a representation from any transferee that such
transferee is an accredited investor, or (C)(1) it is an insurance company, (2)
the source of funds used to acquire or hold this Certificate or any interest
therein is an "insurance company general account," as such term is defined in
Prohibited Transaction Class Exemption ("PTCE") 95-60, and (3) the conditions in
Sections I and III of PTCE 95-60 have been satisfied.

            If this Certificate or any interest therein is acquired or held in
violation of the provisions of Section 5.02(c) of the Agreement, the next
preceding permitted beneficial owner will be treated as the beneficial owner of
this Certificate retroactive to the date of transfer to the purported beneficial
owner. Any purported beneficial owner whose acquisition or holding of any this
Certificate or any interest therein was effected in violation of the provisions
of Section 5.02(c) of the Agreement shall indemnify and hold harmless the
Depositor, the Servicer, the Trustee and the Trust Fund from and against any and
all liabilities, claims, costs or expenses incurred by those parties as a result
of that acquisition or holding.

            The Certificates are issuable in fully registered form only without
coupons in Classes and denominations representing Percentage Interests specified
in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, the Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.
No service charge will be made for any such registration of transfer or exchange
of Certificates, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection
with any transfer or exchange of Certificates.

            The Depositor, the Servicer, the Trustee and any agent of the
Depositor, the Servicer or the Trustee may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes, and none of the
Depositor, the Servicer, the Trustee nor any such agent shall be affected by
notice to the contrary.

            The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts
held by the Trustee and required to be paid to them pursuant to the Agreement
following the earlier of (i) the final payment or other liquidation (or any
advance with respect thereto) of the last Mortgage Loan and REO Property
remaining in REMIC I and (ii) the purchase by the party designated in the
Agreement at a price determined as provided in the Agreement from REMIC I of all
the Mortgage Loans and all property acquired in respect of such Mortgage Loans.
The Agreement permits, but does not require, the party designated in the
Agreement to purchase from REMIC I all the Mortgage Loans and all property
acquired in respect of any Mortgage Loan at a price determined as provided in
the Agreement. The exercise of such right will effect early retirement of the
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Loans at the time of purchase being less than
10% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-off Date.

by

                    STANWICH ASSET ACCEPTANCE COMPANY, L.L.C.

      THIS CERTIFICATE DOES NOT REPRESENT AN OBLIGATION OF OR INTEREST IN
      STANWICH ASSET ACCEPTANCE COMPANY, L.L.C., THE SERVICER, THE TRUSTEE
      OR ANY OF THEIR RESPECTIVE AFFILIATES. NEITHER THIS CERTIFICATE NOR

      INSTRUMENTALITY OF THE UNITED STATES.

            This certifies that Cede & Co. is the registered owner of a

Trustee, a summary of certain of the pertinent provisions of which is set forth
hereafter. To the extent not defined herein, the capitalized terms used herein
have the meanings assigned in the Agreement. This Certificate is issued under

which Agreement the Holder of this Certificate by virtue of the acceptance
hereof assents and by which such Holder is bound.

            Pursuant to the terms of the Agreement, distributions will be made
on the 25th day of each month or, if such 25th day is not a Business Day, the
Business Day immediately following (a "Distribution Date"), commencing on the
First Distribution Date specified above, to the Person in whose name this
Certificate is registered on the Record Date, in an amount equal to the product
of the Percentage Interest evidenced by this Certificate and the amount required
to be distributed to the Holders of Class A-2 Certificates on such Distribution
Date pursuant to the Agreement.

            All distributions to the Holder of this Certificate under the

            The Pass-Through Rate applicable to the calculation of interest
payable with respect to this Certificate on any Distribution Date shall equal a
rate per annum equal to the lesser of (i) the related Formula Rate for such
Distribution Date and (ii) the related Net WAC Pass-Through Rate for such
Distribution Date.

            This Certificate is one of a duly authorized issue of Certificates
designated as Asset Backed Pass-Through Certificates of the Series specified on
the face hereof (herein called the "Certificates") and representing a Percentage
Interest in the Class of Certificates specified on the face hereof equal to the
denomination specified on the face hereof divided by the aggregate Certificate
Principal Balance of the Class of Certificates specified on the face hereof.

            The Certificates are limited in right of payment to certain
collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Collection Account and the Distribution Account
may be made from time to time for purposes other than distributions to
Certificateholders, such purposes including reimbursement of advances made, or
certain expenses incurred, with respect to the Mortgage Loans.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Servicer, the Trustee, and the rights of the Certificateholders
under the Agreement at any time by the Depositor, the Servicer and the Trustee
with the consent of the Holders of Certificates entitled to at least 66% of the
Voting Rights. Any such consent by the Holder of this Certificate shall be
conclusive and binding on such Holder and upon all future Holders of this
Certificate and of any Certificate issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain limited circumstances, without the consent of the Holders of any of the
Certificates.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices or agencies appointed by the Trustee as provided in the
Agreement, duly endorsed by, or accompanied by an assignment in the form below
or other written instrument of transfer in form satisfactory to the Trustee duly
executed by, the Holder hereof or such Holder's attorney duly authorized in
writing, and thereupon one or more new Certificates of the same Class in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            Each beneficial owner of this Certificate or any interest therein
shall be deemed to have represented, by virtue of its acquisition or holding of
such Certificate or any interest therein, that either (A) it is not an "employee
benefit plan" as defined in Section 3(3) of the Employee Retirement Income
Security Act of 1974, as amended ("ERISA"), that is subject to Title I of ERISA,
any "plan" as defined in Section 4975(e)(1) of the Internal Revenue Code of
1986, as amended (the "Code"), that is subject to Section 4975 of the Code or
any entity deemed to hold plan assets of any of the foregoing, (B) it has
acquired and is holding this Certificate in reliance on the underwriters'
exemption, and that it understands that there are certain conditions to the
availability of the underwriters' exemption, including that this Certificate
must be rated, at

                                      A-2-3

the time of purchase, not lower than "BBB-" (or its equivalent) by Fitch, S&P or
Moody's and the Certificate is so rated, that it is an accredited investor as
defined in Rule 501(a)(1) of Regulation D of the Securities Act of 1933, as
amended, and that it will obtain a representation from any transferee that such
transferee is an accredited investor, or (C)(1) it is an insurance company, (2)
the source of funds used to acquire or hold this Certificate or any interest
therein is an "insurance company general account," as such term is defined in
Prohibited Transaction Class Exemption ("PTCE") 95-60, and (3) the conditions in
Sections I and III of PTCE 95-60 have been satisfied.

            If this Certificate or any interest therein is acquired or held in
violation of the provisions of Section 5.02(c) of the Agreement, the next
preceding permitted beneficial owner will be treated as the beneficial owner of
this Certificate retroactive to the date of transfer to the purported beneficial
owner. Any purported beneficial owner whose acquisition or holding of any this
Certificate or any interest therein was effected in violation of the provisions
of Section 5.02(c) of the Agreement shall indemnify and hold harmless the
Depositor, the Servicer, the Trustee and the Trust Fund from and against any and
all liabilities, claims, costs or expenses incurred by those parties as a result
of that acquisition or holding.

            The Certificates are issuable in fully registered form only without
coupons in Classes and denominations representing Percentage Interests specified
in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, the Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.
No service charge will be made for any such registration of transfer or exchange
of Certificates, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection
with any transfer or exchange of Certificates.

            The Depositor, the Servicer, the Trustee and any agent of the
Depositor, the Servicer or the Trustee may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes, and none of the
Depositor, the Servicer, the Trustee nor any such agent shall be affected by
notice to the contrary.

            The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts
held by the Trustee and required to be paid to them pursuant to the Agreement
following the earlier of (i) the final payment or other liquidation (or any
advance with respect thereto) of the last Mortgage Loan and REO Property
remaining in REMIC I and (ii) the purchase by the party designated in the
Agreement at a price determined as provided in the Agreement from REMIC I of all
the Mortgage Loans and all property acquired in respect of such Mortgage Loans.
The Agreement permits, but does not require, the party designated in the
Agreement to purchase from REMIC I all the Mortgage Loans and all property
acquired in respect of any Mortgage Loan at a price determined as provided in
the Agreement. The exercise of such right will effect early retirement of the
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Loans at the time of purchase being less than
10% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-off Date.

                                      A-2-4

            The recitals contained herein shall be taken as statements of the
Depositor and the Trustee assumes no responsibility for their correctness.

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

                                      A-2-5

            IN WITNESS WHEREOF, the Trustee has caused this Certificate to be
duly executed.

certain limited circumstances, without the consent of the Holders of any of the

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices or agencies appointed by the Trustee as provided in the

            Each beneficial owner of this Certificate or any interest therein
shall be deemed to have represented, by virtue of its acquisition or holding of
such Certificate or any interest therein, that either (A) it is not an "employee
benefit plan" as defined in Section 3(3) of the Employee Retirement Income
Security Act of 1974, as amended ("ERISA"), that is subject to Title I of ERISA,
any "plan" as defined in Section 4975(e)(1) of the Internal Revenue Code of
1986, as amended (the "Code"), that is subject to Section 4975 of the Code or
any entity deemed to hold plan assets of any of the foregoing, (B) it has
acquired and is holding this Certificate in reliance on the underwriters'
exemption, and that it understands that there are certain conditions to the
availability of the underwriters' exemption, including that this Certificate
must be rated, at

                                      A-3-3

the time of purchase, not lower than "BBB-" (or its equivalent) by Fitch, S&P or
Moody's and the Certificate is so rated, that it is an accredited investor as
defined in Rule 501(a)(1) of Regulation D of the Securities Act of 1933, as
amended, and that it will obtain a representation from any transferee that such
transferee is an accredited investor, or (C)(1) it is an insurance company, (2)
the source of funds used to acquire or hold this Certificate or any interest
therein is an "insurance company general account," as such term is defined in
Prohibited Transaction Class Exemption ("PTCE") 95-60, and (3) the conditions in
Sections I and III of PTCE 95-60 have been satisfied.

            If this Certificate or any interest therein is acquired or held in
violation of the provisions of Section 5.02(c) of the Agreement, the next
preceding permitted beneficial owner will be treated as the beneficial owner of
this Certificate retroactive to the date of transfer to the purported beneficial
owner. Any purported beneficial owner whose acquisition or holding of any this
Certificate or any interest therein was effected in violation of the provisions
of Section 5.02(c) of the Agreement shall indemnify and hold harmless the
Depositor, the Servicer, the Trustee and the Trust Fund from and against any and
all liabilities, claims, costs or expenses incurred by those parties as a result
of that acquisition or holding.

            The Certificates are issuable in fully registered form only without
coupons in Classes and denominations representing Percentage Interests specified
in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, the Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.
No service charge will be made for any such registration of transfer or exchange
of Certificates, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection
with any transfer or exchange of Certificates.

            The Depositor, the Servicer, the Trustee and any agent of the
Depositor, the Servicer or the Trustee may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes, and none of the
Depositor, the Servicer, the Trustee nor any such agent shall be affected by
notice to the contrary.

            The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts
held by the Trustee and required to be paid to them pursuant to the Agreement
following the earlier of (i) the final payment or other liquidation (or any
advance with respect thereto) of the last Mortgage Loan and REO Property
remaining in REMIC I and (ii) the purchase by the party designated in the
Agreement at a price determined as provided in the Agreement from REMIC I of all
the Mortgage Loans and all property acquired in respect of such Mortgage Loans.
The Agreement permits, but does not require, the party designated in the
Agreement to purchase from REMIC I all the Mortgage Loans and all property
acquired in respect of any Mortgage Loan at a price determined as provided in
the Agreement. The exercise of such right will effect early retirement of the
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Loans at the time of purchase being less than
10% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-off Date.

the Trustee, by manual signature, this Certificate shall not be entitled to any
benefit under the Agreement or be valid for any purpose.

                                      A-3-5

            IN WITNESS WHEREOF, the Trustee has caused this Certificate to be
duly executed.

by

                    STANWICH ASSET ACCEPTANCE COMPANY, L.L.C.

      THIS CERTIFICATE DOES NOT REPRESENT AN OBLIGATION OF OR INTEREST IN
      STANWICH ASSET ACCEPTANCE COMPANY, L.L.C., THE SERVICER, THE TRUSTEE
      OR ANY OF THEIR RESPECTIVE AFFILIATES. NEITHER THIS CERTIFICATE NOR
      THE UNDERLYING MORTGAGE LOANS ARE GUARANTEED BY ANY AGENCY OR
      INSTRUMENTALITY OF THE UNITED STATES.

            This certifies that Cede & Co. is the registered owner of a

by the aggregate Certificate Principal Balance of the Class M-1 Certificates as
of the Closing Date) in that certain beneficial ownership interest evidenced by

Servicing Agreement, dated as specified above (the "Agreement"), among Stanwich
Asset Acceptance Company, L.L.C. (hereinafter called the "Depositor," which term

Trustee, a summary of certain of the pertinent provisions of which is set forth
hereafter. To the extent not defined herein, the capitalized terms used herein
have the meanings assigned in the Agreement. This Certificate is issued under

which Agreement the Holder of this Certificate by virtue of the acceptance
hereof assents and by which such Holder is bound.

            Pursuant to the terms of the Agreement, distributions will be made
on the 25th day of each month or, if such 25th day is not a Business Day, the
Business Day immediately following (a "Distribution Date"), commencing on the
First Distribution Date specified above, to the Person in whose name this
Certificate is registered on the Record Date, in an amount equal to the product
of the Percentage Interest evidenced by this Certificate and the amount required
to be distributed to the Holders of Class M-1 Certificates on such Distribution
Date pursuant to the Agreement.

            All distributions to the Holder of this Certificate under the
Agreement will be made or caused to be made by the Trustee by wire transfer in
immediately available funds to the account of the Person entitled thereto if
such Person shall have so notified the Trustee in writing at least five Business

            The Pass-Through Rate applicable to the calculation of interest
payable with respect to this Certificate on any Distribution Date shall equal a
rate per annum equal to the lesser of (i) the related Formula Rate for such
Distribution Date and (ii) the related Net WAC Pass-Through Rate for such
Distribution Date.

            This Certificate is one of a duly authorized issue of Certificates
designated as Asset Backed Pass-Through Certificates of the Series specified on
the face hereof (herein called the "Certificates") and representing a Percentage
Interest in the Class of Certificates specified on the face hereof equal to the
denomination specified on the face hereof divided by the aggregate Certificate
Principal Balance of the Class of Certificates specified on the face hereof.

            The Certificates are limited in right of payment to certain
collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Collection Account and the Distribution Account
may be made from time to time for purposes other than distributions to
Certificateholders, such purposes including reimbursement of advances made, or
certain expenses incurred, with respect to the Mortgage Loans.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Servicer, the Trustee and the rights of the Certificateholders
under the Agreement at any time by the Depositor, the Servicer and the Trustee
with the consent of the Holders of Certificates entitled to at least 66% of the
Voting Rights. Any such consent by the Holder of this Certificate shall be
conclusive and binding on such Holder and upon all future Holders of this
Certificate and of any Certificate issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain limited circumstances, without the consent of the Holders of any of the
Certificates.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices or agencies appointed by the Trustee as provided in the
Agreement, duly endorsed by, or accompanied by an assignment in the form below
or other written instrument of transfer in form satisfactory to the Trustee duly
executed by, the Holder hereof or such Holder's attorney duly authorized in
writing, and thereupon one or more new Certificates of the same Class in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            Each beneficial owner of this Certificate or any interest therein
shall be deemed to have represented, by virtue of its acquisition or holding of
such Certificate or any interest therein, that either (A) it is not an "employee
benefit plan" as defined in Section 3(3) of the Employee Retirement Income
Security Act of 1974, as amended ("ERISA"), that is subject to Title I of ERISA,
any "plan" as defined in Section 4975(e)(1) of the Internal Revenue Code of
1986, as amended (the "Code"), that is subject to Section 4975 of the Code or
any entity deemed to hold plan assets of any of the foregoing, (B) it has
acquired and is holding this Certificate in reliance on the underwriters'
exemption, and that it understands that there are certain conditions to the
availability of the underwriters' exemption, including that this Certificate
must be rated, at

                                      A-5-3

the time of purchase, not lower than "BBB-" (or its equivalent) by Fitch, S&P or
Moody's and the Certificate is so rated, that it is an accredited investor as
defined in Rule 501(a)(1) of Regulation D of the Securities Act of 1933, as
amended, and that it will obtain a representation from any transferee that such
transferee is an accredited investor, or (C)(1) it is an insurance company, (2)
the source of funds used to acquire or hold this Certificate or any interest
therein is an "insurance company general account," as such term is defined in
Prohibited Transaction Class Exemption ("PTCE") 95-60, and (3) the conditions in
Sections I and III of PTCE 95-60 have been satisfied.

            If this Certificate or any interest therein is acquired or held in
violation of the provisions of Section 5.02(c) of the Agreement, the next
preceding permitted beneficial owner will be treated as the beneficial owner of
this Certificate retroactive to the date of transfer to the purported beneficial
owner. Any purported beneficial owner whose acquisition or holding of any this
Certificate or any interest therein was effected in violation of the provisions
of Section 5.02(c) of the Agreement shall indemnify and hold harmless the
Depositor, the Servicer, the Trustee and the Trust Fund from and against any and
all liabilities, claims, costs or expenses incurred by those parties as a result
of that acquisition or holding.

            The Certificates are issuable in fully registered form only without
coupons in Classes and denominations representing Percentage Interests specified
in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, the Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.
No service charge will be made for any such registration of transfer or exchange
of Certificates, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection
with any transfer or exchange of Certificates.

            The Depositor, the Servicer, the Trustee and any agent of the
Depositor, the Servicer or the Trustee may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes, and none of the
Depositor, the Servicer, the Trustee nor any such agent shall be affected by
notice to the contrary.

            The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts
held by the Trustee and required to be paid to them pursuant to the Agreement
following the earlier of (i) the final payment or other liquidation (or any
advance with respect thereto) of the last Mortgage Loan and REO Property
remaining in REMIC I and (ii) the purchase by the party designated in the
Agreement at a price determined as provided in the Agreement from REMIC I of all
the Mortgage Loans and all property acquired in respect of such Mortgage Loans.
The Agreement permits, but does not require, the party designated in the
Agreement to purchase from REMIC I all the Mortgage Loans and all property
acquired in respect of any Mortgage Loan at a price determined as provided in
the Agreement. The exercise of such right will effect early retirement of the
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Loans at the time of purchase being less than
10% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-off Date.

                                      A-5-4

            The recitals contained herein shall be taken as statements of the
Depositor and the Trustee assumes no responsibility for their correctness.

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

                                      A-5-5

            IN WITNESS WHEREOF, the Trustee has caused this Certificate to be
duly executed.

therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices or agencies appointed by the Trustee as provided in the

shall be deemed to have represented, by virtue of its acquisition or holding of
such Certificate or any interest therein, that either (A) it is not an "employee
benefit plan" as defined in Section 3(3) of the Employee Retirement Income
Security Act of 1974, as amended ("ERISA"), that is subject to Title I of ERISA,
any "plan" as defined in Section 4975(e)(1) of the Internal Revenue Code of
1986, as amended (the "Code"), that is subject to Section 4975 of the Code or
any entity deemed to hold plan assets of any of the foregoing, (B) it has
acquired and is holding this Certificate in reliance on the underwriters'
exemption, and that it understands that there are certain conditions to the
availability of the underwriters' exemption, including that this Certificate
must be rated, at

                                      A-6-3

the time of purchase, not lower than "BBB-" (or its equivalent) by Fitch, S&P or
Moody's and the Certificate is so rated, that it is an accredited investor as
defined in Rule 501(a)(1) of Regulation D of the Securities Act of 1933, as
amended, and that it will obtain a representation from any transferee that such
transferee is an accredited investor, or (C)(1) it is an insurance company, (2)
the source of funds used to acquire or hold this Certificate or any interest
therein is an "insurance company general account," as such term is defined in
Prohibited Transaction Class Exemption ("PTCE") 95-60, and (3) the conditions in
Sections I and III of PTCE 95-60 have been satisfied.

            If this Certificate or any interest therein is acquired or held in
violation of the provisions of Section 5.02(c) of the Agreement, the next
preceding permitted beneficial owner will be treated as the beneficial owner of
this Certificate retroactive to the date of transfer to the purported beneficial
owner. Any purported beneficial owner whose acquisition or holding of any this
Certificate or any interest therein was effected in violation of the provisions
of Section 5.02(c) of the Agreement shall indemnify and hold harmless the
Depositor, the Servicer, the Trustee and the Trust Fund from and against any and
all liabilities, claims, costs or expenses incurred by those parties as a result
of that acquisition or holding.

            The Certificates are issuable in fully registered form only without
coupons in Classes and denominations representing Percentage Interests specified
in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, the Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.
No service charge will be made for any such registration of transfer or exchange
of Certificates, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection
with any transfer or exchange of Certificates.

            The Depositor, the Servicer, the Trustee and any agent of the
Depositor, the Servicer or the Trustee may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes, and none of the
Depositor, the Servicer, the Trustee nor any such agent shall be affected by
notice to the contrary.

            The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts
held by the Trustee and required to be paid to them pursuant to the Agreement
following the earlier of (i) the final payment or other liquidation (or any
advance with respect thereto) of the last Mortgage Loan and REO Property
remaining in REMIC I and (ii) the purchase by the party designated in the
Agreement at a price determined as provided in the Agreement from REMIC I of all
the Mortgage Loans and all property acquired in respect of such Mortgage Loans.
The Agreement permits, but does not require, the party designated in the
Agreement to purchase from REMIC I all the Mortgage Loans and all property
acquired in respect of any Mortgage Loan at a price determined as provided in
the Agreement. The exercise of such right will effect early retirement of the
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Loans at the time of purchase being less than
10% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-off Date.

                                      A-6-4

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

                                      A-6-5

            IN WITNESS WHEREOF, the Trustee has caused this Certificate to be
duly executed.

                    STANWICH ASSET ACCEPTANCE COMPANY, L.L.C.

      THIS CERTIFICATE DOES NOT REPRESENT AN OBLIGATION OF OR INTEREST IN

Distribution Date.

            This Certificate is one of a duly authorized issue of Certificates
designated as Asset Backed Pass-Through Certificates of the Series specified on
the face hereof (herein called the "Certificates") and representing a Percentage
Interest in the Class of Certificates specified on the face hereof equal to the

Principal Balance of the Class of Certificates specified on the face hereof.

            The Certificates are limited in right of payment to certain
collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Collection Account and the Distribution Account
may be made from time to time for purposes other than distributions to
Certificateholders, such purposes including reimbursement of advances made, or
certain expenses incurred, with respect to the Mortgage Loans.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Servicer, the Trustee and the rights of the Certificateholders
under the Agreement at any time by the Depositor, the Servicer and the Trustee
with the consent of the Holders of Certificates entitled to at least 66% of the
Voting Rights. Any such consent by the Holder of this Certificate shall be
conclusive and binding on such Holder and upon all future Holders of this
Certificate and of any Certificate issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain limited circumstances, without the consent of the Holders of any of the
Certificates.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices or agencies appointed by the Trustee as provided in the
Agreement, duly endorsed by, or accompanied by an assignment in the form below
or other written instrument of transfer in form satisfactory to the Trustee duly
executed by, the Holder hereof or such Holder's attorney duly authorized in
writing, and thereupon one or more new Certificates of the same Class in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            Each beneficial owner of this Certificate or any interest therein
shall be deemed to have represented, by virtue of its acquisition or holding of
such Certificate or any interest therein, that either (A) it is not an "employee
benefit plan" as defined in Section 3(3) of the Employee Retirement Income
Security Act of 1974, as amended ("ERISA"), that is subject to Title I of ERISA,
any "plan" as defined in Section 4975(e)(1) of the Internal Revenue Code of
1986, as amended (the "Code"), that is subject to Section 4975 of the Code or
any entity deemed to hold plan assets of any of the foregoing, (B) it has
acquired and is holding this Certificate in reliance on the underwriters'
exemption, and that it understands that there are certain conditions to the
availability of the underwriters' exemption, including that this Certificate
must be rated, at

                                      A-8-3

the time of purchase, not lower than "BBB-" (or its equivalent) by Fitch, S&P or
Moody's and the Certificate is so rated, that it is an accredited investor as
defined in Rule 501(a)(1) of Regulation D of the Securities Act of 1933, as
amended, and that it will obtain a representation from any transferee that such
transferee is an accredited investor, or (C)(1) it is an insurance company, (2)
the source of funds used to acquire or hold this Certificate or any interest
therein is an "insurance company general account," as such term is defined in
Prohibited Transaction Class Exemption ("PTCE") 95-60, and (3) the conditions in
Sections I and III of PTCE 95-60 have been satisfied.

            If this Certificate or any interest therein is acquired or held in
violation of the provisions of Section 5.02(c) of the Agreement, the next
preceding permitted beneficial owner will be treated as the beneficial owner of
this Certificate retroactive to the date of transfer to the purported beneficial
owner. Any purported beneficial owner whose acquisition or holding of any this
Certificate or any interest therein was effected in violation of the provisions
of Section 5.02(c) of the Agreement shall indemnify and hold harmless the
Depositor, the Servicer, the Trustee and the Trust Fund from and against any and
all liabilities, claims, costs or expenses incurred by those parties as a result
of that acquisition or holding.

            The Certificates are issuable in fully registered form only without
coupons in Classes and denominations representing Percentage Interests specified
in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, the Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.
No service charge will be made for any such registration of transfer or exchange
of Certificates, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection
with any transfer or exchange of Certificates.

            The Depositor, the Servicer, the Trustee and any agent of the
Depositor, the Servicer or the Trustee may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes, and none of the
Depositor, the Servicer, the Trustee nor any such agent shall be affected by
notice to the contrary.

            The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts
held by the Trustee and required to be paid to them pursuant to the Agreement
following the earlier of (i) the final payment or other liquidation (or any
advance with respect thereto) of the last Mortgage Loan and REO Property
remaining in REMIC I and (ii) the purchase by the party designated in the
Agreement at a price determined as provided in the Agreement from REMIC I of all
the Mortgage Loans and all property acquired in respect of such Mortgage Loans.
The Agreement permits, but does not require, the party designated in the
Agreement to purchase from REMIC I all the Mortgage Loans and all property
acquired in respect of any Mortgage Loan at a price determined as provided in
the Agreement. The exercise of such right will effect early retirement of the
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Loans at the time of purchase being less than
10% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-off Date.

benefit under the Agreement or be valid for any purpose.

                                      A-8-5

            IN WITNESS WHEREOF, the Trustee has caused this Certificate to be
duly executed.

Certificate and of any Certificate issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain limited circumstances, without the consent of the Holders of any of the
Certificates.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices or agencies appointed by the Trustee as provided in the
Agreement, duly endorsed by, or accompanied by an assignment in the form below

executed by, the Holder hereof or such Holder's attorney duly authorized in
writing, and thereupon one or more new Certificates of the same Class in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            Each beneficial owner of this Certificate or any interest therein
shall be deemed to have represented, by virtue of its acquisition or holding of
such Certificate or any interest therein, that either (A) it is not an "employee
benefit plan" as defined in Section 3(3) of the Employee Retirement Income
Security Act of 1974, as amended ("ERISA"), that is subject to Title I of ERISA,
any "plan" as defined in Section 4975(e)(1) of the Internal Revenue Code of
1986, as amended (the "Code"), that is subject to Section 4975 of the Code or
any entity deemed to hold plan assets of any of the foregoing, (B) it has
acquired and is holding this Certificate in reliance on the underwriters'
exemption, and that it understands that there are certain conditions to the
availability of the underwriters' exemption, including that this Certificate
must be rated, at

                                      A-9-4

the time of purchase, not lower than "BBB-" (or its equivalent) by Fitch, S&P or
Moody's and the Certificate is so rated, that it is an accredited investor as
defined in Rule 501(a)(1) of Regulation D of the Securities Act of 1933, as
amended, and that it will obtain a representation from any transferee that such
transferee is an accredited investor, or (C)(1) it is an insurance company, (2)
the source of funds used to acquire or hold this Certificate or any interest
therein is an "insurance company general account," as such term is defined in
Prohibited Transaction Class Exemption ("PTCE") 95-60, and (3) the conditions in
Sections I and III of PTCE 95-60 have been satisfied.

            If this Certificate or any interest therein is acquired or held in
violation of the provisions of Section 5.02(c) of the Agreement, the next
preceding permitted beneficial owner will be treated as the beneficial owner of
this Certificate retroactive to the date of transfer to the purported beneficial
owner. Any purported beneficial owner whose acquisition or holding of any this
Certificate or any interest therein was effected in violation of the provisions
of Section 5.02(c) of the Agreement shall indemnify and hold harmless the
Depositor, the Servicer, the Trustee and the Trust Fund from and against any and
all liabilities, claims, costs or expenses incurred by those parties as a result
of that acquisition or holding.

            The Certificates are issuable in fully registered form only without
coupons in Classes and denominations representing Percentage Interests specified
in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, the Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.
No service charge will be made for any such registration of transfer or exchange
of Certificates, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection
with any transfer or exchange of Certificates.

            The Depositor, the Servicer, the Trustee and any agent of the
Depositor, the Servicer or the Trustee may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes, and none of the
Depositor, the Servicer, the Trustee nor any such agent shall be affected by
notice to the contrary.

            The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts
held by the Trustee and required to be paid to them pursuant to the Agreement
following the earlier of (i) the final payment or other liquidation (or any
advance with respect thereto) of the last Mortgage Loan and REO Property
remaining in REMIC I and (ii) the purchase by the party designated in the
Agreement at a price determined as provided in the Agreement from REMIC I of all
the Mortgage Loans and all property acquired in respect of such Mortgage Loans.
The Agreement permits, but does not require, the party designated in the
Agreement to purchase from REMIC I all the Mortgage Loans and all property
acquired in respect of any Mortgage Loan at a price determined as provided in
the Agreement. The exercise of such right will effect early retirement of the
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Loans at the time of purchase being less than
10% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-off Date.

                                      A-9-5

Depositor and the Trustee assumes no responsibility for their correctness.

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

                                      A-9-6

            IN WITNESS WHEREOF, the Trustee has caused this Certificate to be
duly executed.

transferee is an accredited investor, or (C)(1) it is an insurance company, (2)
the source of funds used to acquire or hold this Certificate or any interest
therein is an "insurance company general account," as such term is defined in
Prohibited Transaction Class Exemption ("PTCE") 95-60, and (3) the conditions in
Sections I and III of PTCE 95-60 have been satisfied.

            If this Certificate or any interest therein is acquired or held in
violation of the provisions of Section 5.02(c) of the Agreement, the next
preceding permitted beneficial owner will be treated as the beneficial owner of
this Certificate retroactive to the date of transfer to the purported beneficial
owner. Any purported beneficial owner whose acquisition or holding of any this
Certificate or any interest therein was effected in violation of the provisions
of Section 5.02(c) of the Agreement shall indemnify and hold harmless the
Depositor, the Servicer, the Trustee and the Trust Fund from and against any and
all liabilities, claims, costs or expenses incurred by those parties as a result
of that acquisition or holding.

            The Certificates are issuable in fully registered form only without
coupons in Classes and denominations representing Percentage Interests specified
in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, the Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.
No service charge will be made for any such registration of transfer or exchange
of Certificates, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection
with any transfer or exchange of Certificates.

            The Depositor, the Servicer, the Trustee and any agent of the
Depositor, the Servicer or the Trustee may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes, and none of the
Depositor, the Servicer, the Trustee nor any such agent shall be affected by
notice to the contrary.

            The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts
held by the Trustee and required to be paid to them pursuant to the Agreement
following the earlier of (i) the final payment or other liquidation (or any
advance with respect thereto) of the last Mortgage Loan and REO Property
remaining in REMIC I and (ii) the purchase by the party designated in the
Agreement at a price determined as provided in the Agreement from REMIC I of all
the Mortgage Loans and all property acquired in respect of such Mortgage Loans.
The Agreement permits, but does not require, the party designated in the
Agreement to purchase from REMIC I all the Mortgage Loans and all property
acquired in respect of any Mortgage Loan at a price determined as provided in
the Agreement. The exercise of such right will effect early retirement of the
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Loans at the time of purchase being less than
10% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-off Date.

the Trustee, by manual signature, this Certificate shall not be entitled to any
benefit under the Agreement or be valid for any purpose.

                                     A-10-6

            IN WITNESS WHEREOF, the Trustee has caused this Certificate to be
duly executed.

designated as Asset Backed Pass-Through Certificates of the Series specified on

conclusive and binding on such Holder and upon all future Holders of this
Certificate and of any Certificate issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain limited circumstances, without the consent of the Holders of any of the
Certificates.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices or agencies appointed by the Trustee as provided in the
Agreement, duly endorsed by, or accompanied by an assignment in the form below
or other written instrument of transfer in form satisfactory to the Trustee duly
executed by, the Holder hereof or such Holder's attorney duly authorized in
writing, and thereupon one or more new Certificates of the same Class in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            Each beneficial owner of this Certificate or any interest therein
shall be deemed to have represented, by virtue of its acquisition or holding of
such Certificate or any interest therein, that either (A) it is not an "employee
benefit plan" as defined in Section 3(3) of the Employee Retirement Income
Security Act of 1974, as amended ("ERISA"), that is subject to Title I of ERISA,
any "plan" as defined in Section 4975(e)(1) of the Internal Revenue Code of
1986, as amended (the "Code"), that is subject to Section 4975 of the Code or
any entity deemed to hold plan assets of any of the foregoing, (B) it has
acquired and is holding this Certificate in reliance on the underwriters'
exemption, and that it understands that there are certain conditions to the
availability of the underwriters' exemption, including that this Certificate
must be rated, at

                                     A-11-4

the time of purchase, not lower than "BBB-" (or its equivalent) by Fitch, S&P or
Moody's and the Certificate is so rated, that it is an accredited investor as
defined in Rule 501(a)(1) of Regulation D of the Securities Act of 1933, as
amended, and that it will obtain a representation from any transferee that such
transferee is an accredited investor, or (C)(1) it is an insurance company, (2)
the source of funds used to acquire or hold this Certificate or any interest
therein is an "insurance company general account," as such term is defined in
Prohibited Transaction Class Exemption ("PTCE") 95-60, and (3) the conditions in
Sections I and III of PTCE 95-60 have been satisfied.

            If this Certificate or any interest therein is acquired or held in
violation of the provisions of Section 5.02(c) of the Agreement, the next
preceding permitted beneficial owner will be treated as the beneficial owner of
this Certificate retroactive to the date of transfer to the purported beneficial
owner. Any purported beneficial owner whose acquisition or holding of any this
Certificate or any interest therein was effected in violation of the provisions
of Section 5.02(c) of the Agreement shall indemnify and hold harmless the
Depositor, the Servicer, the Trustee and the Trust Fund from and against any and
all liabilities, claims, costs or expenses incurred by those parties as a result
of that acquisition or holding.

            The Certificates are issuable in fully registered form only without
coupons in Classes and denominations representing Percentage Interests specified
in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, the Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.
No service charge will be made for any such registration of transfer or exchange
of Certificates, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection
with any transfer or exchange of Certificates.

            The Depositor, the Servicer, the Trustee and any agent of the
Depositor, the Servicer or the Trustee may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes, and none of the
Depositor, the Servicer, the Trustee nor any such agent shall be affected by
notice to the contrary.

            The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts
held by the Trustee and required to be paid to them pursuant to the Agreement
following the earlier of (i) the final payment or other liquidation (or any
advance with respect thereto) of the last Mortgage Loan and REO Property
remaining in REMIC I and (ii) the purchase by the party designated in the
Agreement at a price determined as provided in the Agreement from REMIC I of all
the Mortgage Loans and all property acquired in respect of such Mortgage Loans.
The Agreement permits, but does not require, the party designated in the
Agreement to purchase from REMIC I all the Mortgage Loans and all property
acquired in respect of any Mortgage Loan at a price determined as provided in
the Agreement. The exercise of such right will effect early retirement of the
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Loans at the time of purchase being less than
10% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-off Date.

benefit under the Agreement or be valid for any purpose.

                                     A-11-6

            IN WITNESS WHEREOF, the Trustee has caused this Certificate to be
duly executed.

hereof assents and by which such Holder is bound.

            Pursuant to the terms of the Agreement, distributions will be made

payable with respect to this Certificate on any Distribution Date shall equal a

Distribution Date.

            This Certificate is one of a duly authorized issue of Certificates
designated as Asset Backed Pass-Through Certificates of the Series specified on

Interest in the Class of Certificates specified on the face hereof equal to the

Principal Balance of the Class of Certificates specified on the face hereof.

            The Certificates are limited in right of payment to certain
collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Collection Account and the Distribution Account
may be made from time to time for purposes other than distributions to
Certificateholders, such purposes including reimbursement of advances made, or
certain expenses incurred, with respect to the Mortgage Loans.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Servicer, the Trustee and the rights of the Certificateholders
under the Agreement at any time by the Depositor, the Servicer and the Trustee

Voting Rights. Any such consent by the Holder of this Certificate shall be
conclusive and binding on such Holder and upon all future Holders of this
Certificate and of any Certificate issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain limited circumstances, without the consent of the Holders of any of the
Certificates.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices or agencies appointed by the Trustee as provided in the
Agreement, duly endorsed by, or accompanied by an assignment in the form below
or other written instrument of transfer in form satisfactory to the Trustee duly
executed by, the Holder hereof or such Holder's attorney duly authorized in
writing, and thereupon one or more new Certificates of the same Class in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            Each beneficial owner of this Certificate or any interest therein
shall be deemed to have represented, by virtue of its acquisition or holding of
such Certificate or any interest therein, that either (A) it is not an "employee
benefit plan" as defined in Section 3(3) of the Employee Retirement Income
Security Act of 1974, as amended ("ERISA"), that is subject to Title I of ERISA,
any "plan" as defined in Section 4975(e)(1) of the Internal Revenue Code of
1986, as amended (the "Code"), that is subject to Section 4975 of the Code or
any entity deemed to hold plan assets of any of the foregoing, (B) it has
acquired and is holding this Certificate in reliance on the underwriters'
exemption, and that it understands that there are certain conditions to the
availability of the underwriters' exemption, including that this Certificate
must be rated, at

                                     A-12-4

the time of purchase, not lower than "BBB-" (or its equivalent) by Fitch, S&P or
Moody's and the Certificate is so rated, that it is an accredited investor as
defined in Rule 501(a)(1) of Regulation D of the Securities Act of 1933, as
amended, and that it will obtain a representation from any transferee that such
transferee is an accredited investor, or (C)(1) it is an insurance company, (2)
the source of funds used to acquire or hold this Certificate or any interest
therein is an "insurance company general account," as such term is defined in
Prohibited Transaction Class Exemption ("PTCE") 95-60, and (3) the conditions in
Sections I and III of PTCE 95-60 have been satisfied.

            If this Certificate or any interest therein is acquired or held in
violation of the provisions of Section 5.02(c) of the Agreement, the next
preceding permitted beneficial owner will be treated as the beneficial owner of
this Certificate retroactive to the date of transfer to the purported beneficial
owner. Any purported beneficial owner whose acquisition or holding of any this
Certificate or any interest therein was effected in violation of the provisions
of Section 5.02(c) of the Agreement shall indemnify and hold harmless the
Depositor, the Servicer, the Trustee and the Trust Fund from and against any and
all liabilities, claims, costs or expenses incurred by those parties as a result
of that acquisition or holding.

            The Certificates are issuable in fully registered form only without
coupons in Classes and denominations representing Percentage Interests specified
in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, the Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.
No service charge will be made for any such registration of transfer or exchange
of Certificates, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection
with any transfer or exchange of Certificates.

            The Depositor, the Servicer, the Trustee and any agent of the
Depositor, the Servicer or the Trustee may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes, and none of the
Depositor, the Servicer, the Trustee nor any such agent shall be affected by
notice to the contrary.

            The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts
held by the Trustee and required to be paid to them pursuant to the Agreement
following the earlier of (i) the final payment or other liquidation (or any
advance with respect thereto) of the last Mortgage Loan and REO Property
remaining in REMIC I and (ii) the purchase by the party designated in the
Agreement at a price determined as provided in the Agreement from REMIC I of all
the Mortgage Loans and all property acquired in respect of such Mortgage Loans.
The Agreement permits, but does not require, the party designated in the
Agreement to purchase from REMIC I all the Mortgage Loans and all property
acquired in respect of any Mortgage Loan at a price determined as provided in
the Agreement. The exercise of such right will effect early retirement of the
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Loans at the time of purchase being less than
10% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-off Date.

                                     A-12-5

            The recitals contained herein shall be taken as statements of the
Depositor and the Trustee assumes no responsibility for their correctness.

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

                                     A-12-6

            IN WITNESS WHEREOF, the Trustee has caused this Certificate to be
duly executed.

transfer at the offices or agencies appointed by the Trustee as provided in the
Agreement, duly endorsed by, or accompanied by an assignment in the form below
or other written instrument of transfer in form satisfactory to the Trustee duly
executed by, the Holder hereof or such Holder's attorney duly authorized in
writing, and thereupon one or more new Certificates of the same Class in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            Each beneficial owner of this Certificate or any interest therein
shall be deemed to have represented, by virtue of its acquisition or holding of
such Certificate or any interest therein, that either (A) it is not an "employee
benefit plan" as defined in Section 3(3) of the Employee Retirement Income
Security Act of 1974, as amended ("ERISA"), that is subject to Title I of ERISA,
any "plan" as defined in Section 4975(e)(1) of the Internal Revenue Code of
1986, as amended (the "Code"), that is subject to Section 4975 of the Code or
any entity deemed to hold plan assets of any of the foregoing, (B) it has
acquired and is holding this Certificate in reliance on the underwriters'
exemption, and that it understands that there are certain conditions to the
availability of the underwriters' exemption, including that this Certificate
must be rated, at

                                     A-13-4

the time of purchase, not lower than "BBB-" (or its equivalent) by Fitch, S&P or
Moody's and the Certificate is so rated, that it is an accredited investor as
defined in Rule 501(a)(1) of Regulation D of the Securities Act of 1933, as
amended, and that it will obtain a representation from any transferee that such
transferee is an accredited investor, or (C)(1) it is an insurance company, (2)
the source of funds used to acquire or hold this Certificate or any interest
therein is an "insurance company general account," as such term is defined in
Prohibited Transaction Class Exemption ("PTCE") 95-60, and (3) the conditions in
Sections I and III of PTCE 95-60 have been satisfied.

            If this Certificate or any interest therein is acquired or held in
violation of the provisions of Section 5.02(c) of the Agreement, the next
preceding permitted beneficial owner will be treated as the beneficial owner of
this Certificate retroactive to the date of transfer to the purported beneficial
owner. Any purported beneficial owner whose acquisition or holding of any this
Certificate or any interest therein was effected in violation of the provisions
of Section 5.02(c) of the Agreement shall indemnify and hold harmless the
Depositor, the Servicer, the Trustee and the Trust Fund from and against any and
all liabilities, claims, costs or expenses incurred by those parties as a result
of that acquisition or holding.

            The Certificates are issuable in fully registered form only without
coupons in Classes and denominations representing Percentage Interests specified
in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, the Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.
No service charge will be made for any such registration of transfer or exchange
of Certificates, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection
with any transfer or exchange of Certificates.

            The Depositor, the Servicer, the Trustee and any agent of the
Depositor, the Servicer or the Trustee may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes, and none of the
Depositor, the Servicer, the Trustee nor any such agent shall be affected by
notice to the contrary.

            The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts
held by the Trustee and required to be paid to them pursuant to the Agreement
following the earlier of (i) the final payment or other liquidation (or any
advance with respect thereto) of the last Mortgage Loan and REO Property
remaining in REMIC I and (ii) the purchase by the party designated in the
Agreement at a price determined as provided in the Agreement from REMIC I of all
the Mortgage Loans and all property acquired in respect of such Mortgage Loans.
The Agreement permits, but does not require, the party designated in the
Agreement to purchase from REMIC I all the Mortgage Loans and all property
acquired in respect of any Mortgage Loan at a price determined as provided in
the Agreement. The exercise of such right will effect early retirement of the
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Loans at the time of purchase being less than
10% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-off Date.

benefit under the Agreement or be valid for any purpose.

                                     A-13-6

            This Certificate is one of a duly authorized issue of Certificates
designated as Asset Backed Pass-Through Certificates of the Series specified on
the face hereof (herein called the "Certificates") and representing a Percentage
Interest in the Class of Certificates specified on the face hereof equal to the
denomination specified on the face hereof divided by the aggregate Certificate

collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Collection Account and the Distribution Account

Certificateholders, such purposes including reimbursement of advances made, or
certain expenses incurred, with respect to the Mortgage Loans.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Servicer, the Trustee and the rights of the Certificateholders

writing, and thereupon one or more new Certificates of the same Class in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            No transfer of this Certificate shall be made unless the transfer is
made pursuant to an effective registration statement under the Securities Act of
1933, as amended (the "1933 Act"), and an effective registration or

transaction that does not require such registration or qualification. In the
event that such a transfer of this Certificate is to be made without
registration or qualification, the Trustee shall require receipt of written
certifications from the Holder of the Certificate desiring to effect the
transfer, and from such Holder's prospective transferee, substantially in the
forms attached to the Agreement as Exhibit F-1. None of the Depositor or the
Trustee is obligated to register or qualify the Class of Certificates specified

securities law or to take any action not otherwise required under the Agreement
to permit the transfer of such Certificates without registration or
qualification. Any Holder desiring to effect a transfer of this Certificate
shall be required to indemnify the Trustee, the Depositor and the Servicer
against any liability that may result if the transfer is not so exempt or is not
made in accordance with such federal and state laws.

            Each beneficial owner of this Certificate or any interest therein
shall be deemed to have represented, by virtue of its acquisition or holding of
such Certificate or any interest therein, that either (A) it is not an "employee
benefit plan" as defined in Section 3(3) of the Employee Retirement Income
Security Act of 1974, as amended ("ERISA"), that is subject to Title I of ERISA,
any "plan" as defined in Section 4975(e)(1) of the Internal Revenue Code of
1986, as amended (the "Code"), that is subject to Section 4975 of the Code or
any entity deemed to hold plan assets of any of the foregoing, (B) it has
acquired and is holding this Certificate in reliance on the underwriters'
exemption, and that it understands that there are certain conditions to the
availability of the underwriters' exemption, including that this Certificate
must be rated, at the time of purchase, not lower than "BBB-" (or its
equivalent) by Fitch, S&P or Moody's and the Certificate is so rated, that it is
an accredited investor as defined in Rule 501(a)(1) of Regulation D of the
Securities Act of 1933, as amended, and that it will obtain a representation
from any transferee that such transferee is an accredited investor, or (C)(1) it
is an insurance company, (2) the source of funds used to acquire or hold this
Certificate or any interest therein is an "insurance company general account,"
as such term is defined in Prohibited Transaction Class Exemption ("PTCE")
95-60, and (3) the conditions in Sections I and III of PTCE 95-60 have been
satisfied.

            If this Certificate or any interest therein is acquired or held in
violation of the provisions of Section 5.02(c) of the Agreement, the next
preceding permitted beneficial owner will be treated as the beneficial owner of
this Certificate retroactive to the date of transfer to the purported beneficial
owner. Any purported beneficial owner whose acquisition or holding of any this
Certificate or any interest therein was effected in violation of the provisions
of Section 5.02(c) of the Agreement shall indemnify and hold harmless the
Depositor, the Servicer, the Trustee and the Trust Fund from and against any and
all liabilities, claims, costs or expenses incurred by those parties as a result
of that acquisition or holding.

            The Certificates are issuable in fully registered form only without
coupons in Classes and denominations representing Percentage Interests specified
in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, the Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.
No service charge will be made for any such registration of transfer or exchange
of Certificates, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection
with any transfer or exchange of Certificates.

            The Depositor, the Servicer, the Trustee and any agent of the
Depositor, the Servicer or the Trustee may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes, and none of the
Depositor, the Servicer, the Trustee nor any such agent shall be affected by
notice to the contrary.

following the earlier of (i) the final payment or other liquidation (or any
advance with respect thereto) of the last Mortgage Loan and REO Property
remaining in REMIC I and (ii) the purchase by the party designated in the

      OR ANY OF THEIR RESPECTIVE AFFILIATES. NEITHER THIS CERTIFICATE NOR

            This certifies that Wells Fargo Bank, N.A., as Indenture Trustee
under the Indenture, dated March 14, 2006, relating to the Carrington NIM Trust

entity under the Agreement), the Servicer and the Trustee, a summary of certain
of the pertinent provisions of which is set forth hereafter. To the extent not
defined herein, the capitalized terms used herein have the meanings assigned in
the Agreement. This Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of
this Certificate by virtue of the acceptance hereof assents and by which such
Holder is bound.

            Pursuant to the terms of the Agreement, distributions will be made
on the 25th day of each month or, if such 25th day is not a Business Day, the

            All distributions to the Holder of this Certificate under the
Agreement will be made or caused to be made by the Trustee by wire transfer in
immediately available funds to the account of the Person entitled thereto if
such Person shall have so notified the Trustee in writing at least five Business

entitled thereto, as such name and address shall appear on the Certificate
Register. Notwithstanding the above, the final distribution on this Certificate
will be made after due notice by the Trustee of the pendency

                                     A-15-4

of such distribution and only upon presentation and surrender of this
Certificate at the office or agency appointed by the Trustee for that purpose as
provided in the Agreement.

            This Certificate is one of a duly authorized issue of Certificates
designated as Asset Backed Pass-Through Certificates of the Series specified on
the face hereof (herein called the "Certificates") and representing a Percentage
Interest in the Class of Certificates specified on the face hereof equal to the
denomination specified on the face hereof divided by the aggregate Certificate
Principal Balance of the Class of Certificates specified on the face hereof.

            The Certificates are limited in right of payment to certain
collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Collection Account and the Distribution Account
may be made from time to time for purposes other than distributions to
Certificateholders, such purposes including reimbursement of advances made, or
certain expenses incurred, with respect to the Mortgage Loans.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Servicer, the Trustee and the rights of the Certificateholders
under the Agreement at any time by the Depositor, the Servicer and the Trustee
with the consent of the Holders of Certificates entitled to at least 66% of the
Voting Rights. Any such consent by the Holder of this Certificate shall be
conclusive and binding on such Holder and upon all future Holders of this
Certificate and of any Certificate issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain limited circumstances, without the consent of the Holders of any of the
Certificates.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices or agencies appointed by the Trustee as provided in the
Agreement, duly endorsed by, or accompanied by an assignment in the form below
or other written instrument of transfer in form satisfactory to the Trustee duly
executed by, the Holder hereof or such Holder's attorney duly authorized in
writing, and thereupon one or more new Certificates of the same Class in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            No transfer of this Certificate shall be made unless the transfer is
made pursuant to an effective registration statement under the Securities Act of
1933, as amended (the "1933 Act"), and an effective registration or
qualification under applicable state securities laws, or is made in a
transaction that does not require such registration or qualification. In the
event that such a transfer of this Certificate is to be made without
registration or qualification, the Trustee shall require receipt of (i) if such
transfer is purportedly being made in reliance upon Rule 144A under the 1933
Act, written certifications from the Holder of the Certificate desiring to
effect the transfer, and from such Holder's prospective transferee,
substantially in the forms attached to the Agreement as Exhibit F-1, and (ii) in
all other cases, an Opinion of Counsel satisfactory to it that such transfer may
be made without such registration or qualification (which Opinion of Counsel
shall not be an expense of the Trust Fund or of the Depositor, the Trustee or
the Servicer in their

                                     A-15-5

respective capacities as such), together with copies of the written
certification(s) of the Holder of the Certificate desiring to effect the
transfer and/or such Holder's prospective transferee upon which such Opinion of
Counsel is based. None of the Depositor or the Trustee is obligated to register
or qualify the Class of Certificates specified on the face hereof under the 1933
Act or any other securities law or to take any action not otherwise required
under the Agreement to permit the transfer of such Certificates without
registration or qualification. Any Holder desiring to effect a transfer of this
Certificate shall be required to indemnify the Trustee, the Depositor and the
Servicer against any liability that may result if the transfer is not so exempt
or is not made in accordance with such federal and state laws.

            No transfer of this Certificate or any interest therein shall be
made to any "employee benefit plan" as defined in Section 3(3) of the Employee
Retirement Income Security Act of 1974, as amended ("ERISA"), that is subject to
Title I of ERISA, any "plan" as defined in Section 4975(e)(1) of the Internal
Revenue Code of 1986, as amended (the "Code"), that is subject to Section 4975
of the Code or any entity deemed to hold plan assets of any of the foregoing
(each, a "Plan"), any Person acting, directly or indirectly, on behalf of any
such Plan or any Person acquiring this Certificate with "plan assets" of a Plan
(within the meaning of the Department of Labor regulation promulgated at 29 C.
F. R. ss. 2510.3-101 ("Plan Assets")), as certified by such transferee in the
form of Exhibit G to the Agreement, unless the Trustee is provided with an
Opinion of Counsel acceptable to and in form and substance satisfactory to the
Depositor, the Trustee and the Servicer to the effect that the purchase and
holding of this Certificate is permissible under applicable law, will not
constitute or result in any non-exempt prohibited transaction under Section 406
of ERISA or Section 4975 of the Code (or comparable provisions of any subsequent
enactments) and will not subject the Depositor, the Servicer, the Trustee or the
Trust Fund to any obligation or liability (including obligations or liabilities
under ERISA or Section 4975 of the Code) in addition to those undertaken in the
Agreement, which Opinion of Counsel shall not be an expense of the Depositor,
the Servicer, the Trustee or the Trust Fund.

            If this Certificate or any interest therein is acquired or held in
violation of the provisions of Section 5.02(c) of the Agreement, the next
preceding permitted beneficial owner will be treated as the beneficial owner of
this Certificate retroactive to the date of transfer to the purported beneficial
owner. Any purported beneficial owner whose acquisition or holding of any this
Certificate or any interest therein was effected in violation of the provisions
of Section 5.02(c) of the Agreement shall indemnify and hold harmless the
Depositor, the Servicer, the Trustee and the Trust Fund from and against any and
all liabilities, claims, costs or expenses incurred by those parties as a result
of that acquisition or holding.

            The Certificates are issuable in fully registered form only without
coupons in Classes and denominations representing Percentage Interests specified
in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, the Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.
No service charge will be made for any such registration of transfer or exchange
of Certificates, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection
with any transfer or exchange of Certificates.

                                     A-15-6

            The Depositor, the Servicer, the Trustee and any agent of the
Depositor, the Servicer or the Trustee may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes, and none of the
Depositor, the Servicer, the Trustee nor any such agent shall be affected by
notice to the contrary.

            The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts
held by the Trustee and required to be paid to them pursuant to the Agreement
following the earlier of (i) the final payment or other liquidation (or any
advance with respect thereto) of the last Mortgage Loan and REO Property
remaining in REMIC I and (ii) the purchase by the party designated in the
Agreement at a price determined as provided in the Agreement from REMIC I of all
the Mortgage Loans and all property acquired in respect of such Mortgage Loans.
The Agreement permits, but does not require, the party designated in the
Agreement to purchase from REMIC I all the Mortgage Loans and all property
acquired in respect of any Mortgage Loan at a price determined as provided in
the Agreement. The exercise of such right will effect early retirement of the
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Loans at the time of purchase being less than
10% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-off Date.

            The recitals contained herein shall be taken as statements of the
Depositor and the Trustee assumes no responsibility for their correctness.

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

                                     A-15-7

            IN WITNESS WHEREOF, the Trustee has caused this Certificate to be
duly executed.

                                     A-16-2

            This Certificate is one of a duly authorized issue of Certificates
designated as Asset Backed Pass-Through Certificates of the Series specified on
the face hereof (herein called the "Certificates") and representing a Percentage
Interest in the Class of Certificates specified on the face hereof equal to the
denomination specified on the face hereof divided by the aggregate Certificate
Principal Balance of the Class of Certificates specified on the face hereof.

            The Certificates are limited in right of payment to certain
collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Collection Account and the Distribution Account
may be made from time to time for purposes other than distributions to
Certificateholders, such purposes including reimbursement of advances made, or
certain expenses incurred, with respect to the Mortgage Loans.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Servicer, the Trustee and the rights of the Certificateholders
under the Agreement at any time by the Depositor, the Servicer and the Trustee
with the consent of the Holders of Certificates entitled to at least 66% of the
Voting Rights. Any such consent by the Holder of this Certificate shall be
conclusive and binding on such Holder and upon all future Holders of this
Certificate and of any Certificate issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain limited circumstances, without the consent of the Holders of any of the
Certificates.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices or agencies appointed by the Trustee as provided in the
Agreement, duly endorsed by, or accompanied by an assignment in the form below
or other written instrument of transfer in form satisfactory to the Trustee duly
executed by, the Holder hereof or such Holder's attorney duly authorized in
writing, and thereupon one or more new Certificates of the same Class in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            No transfer of this Certificate shall be made unless the transfer is
made pursuant to an effective registration statement under the Securities Act of
1933, as amended (the "1933 Act"), and an effective registration or
qualification under applicable state securities laws, or is made in a
transaction that does not require such registration or qualification. In the
event that such a transfer of this Certificate is to be made without
registration or qualification, the Trustee shall require receipt of (i) if such
transfer is purportedly being made in reliance upon Rule 144A under the 1933
Act, written certifications from the Holder of the Certificate desiring to
effect the transfer, and from such Holder's prospective transferee,
substantially in the forms attached to the Agreement as Exhibit F-1, and (ii) in
all other cases, an Opinion of Counsel satisfactory to it that such transfer may
be made without such registration or qualification (which Opinion of Counsel
shall not be an expense of the Trust Fund or of the Depositor, the Trustee or
the Servicer in their respective capacities as such), together with copies of
the written certification(s) of the Holder of the Certificate desiring to effect
the transfer and/or such Holder's prospective transferee upon which such Opinion
of Counsel is based. None of the Depositor or the Trustee is obligated to

                                     A-16-3

register or qualify the Class of Certificates specified on the face hereof under
the 1933 Act or any other securities law or to take any action not otherwise
required under the Agreement to permit the transfer of such Certificates without
registration or qualification. Any Holder desiring to effect a transfer of this
Certificate shall be required to indemnify the Trustee, the Depositor and the
Servicer against any liability that may result if the transfer is not so exempt
or is not made in accordance with such federal and state laws.

            No transfer of this Certificate or any interest therein shall be
made to any "employee benefit plan" as defined in Section 3(3) of the Employee
Retirement Income Security Act of 1974, as amended ("ERISA"), that is subject to
Title I of ERISA, any "plan" as defined in Section 4975(e)(1) of the Internal
Revenue Code of 1986, as amended (the "Code"), that is subject to Section 4975
of the Code or any entity deemed to hold plan assets of any of the foregoing
(each, a "Plan"), any Person acting, directly or indirectly, on behalf of any
such Plan or any Person acquiring this Certificate with "plan assets" of a Plan
(within the meaning of the Department of Labor regulation promulgated at 29 C.
F. R. ss. 2510.3-101 ("Plan Assets")), as certified by such transferee in the
form of Exhibit G to the Agreement, unless the Trustee is provided with an
Opinion of Counsel acceptable to and in form and substance satisfactory to the
Depositor, the Trustee and the Servicer to the effect that the purchase and
holding of this Certificate is permissible under applicable law, will not
constitute or result in any non-exempt prohibited transaction under Section 406
of ERISA or Section 4975 of the Code (or comparable provisions of any subsequent
enactments) and will not subject the Depositor, the Servicer, the Trustee or the
Trust Fund to any obligation or liability (including obligations or liabilities
under ERISA or Section 4975 of the Code) in addition to those undertaken in the
Agreement, which Opinion of Counsel shall not be an expense of the Depositor,
the Servicer, the Trustee or the Trust Fund.

            If this Certificate or any interest therein is acquired or held in
violation of the provisions of Section 5.02(c) of the Agreement, the next
preceding permitted beneficial owner will be treated as the beneficial owner of
this Certificate retroactive to the date of transfer to the purported beneficial
owner. Any purported beneficial owner whose acquisition or holding of any this
Certificate or any interest therein was effected in violation of the provisions
of Section 5.02(c) of the Agreement shall indemnify and hold harmless the
Depositor, the Servicer, the Trustee and the Trust Fund from and against any and
all liabilities, claims, costs or expenses incurred by those parties as a result
of that acquisition or holding.

            The Certificates are issuable in fully registered form only without
coupons in Classes and denominations representing Percentage Interests specified
in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, the Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.
No service charge will be made for any such registration of transfer or exchange
of Certificates, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection
with any transfer or exchange of Certificates.

            The Depositor, the Servicer, the Trustee and any agent of the
Depositor, the Servicer or the Trustee may treat the Person in whose name this
Certificate is registered as the

                                     A-16-4

owner hereof for all purposes, and none of the Depositor, the Servicer, the
Trustee nor any such agent shall be affected by notice to the contrary.

            The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts
held by the Trustee and required to be paid to them pursuant to the Agreement
following the earlier of (i) the final payment or other liquidation (or any
advance with respect thereto) of the last Mortgage Loan and REO Property
remaining in REMIC I and (ii) the purchase by the party designated in the
Agreement at a price determined as provided in the Agreement from REMIC I of all
the Mortgage Loans and all property acquired in respect of such Mortgage Loans.
The Agreement permits, but does not require, the party designated in the
Agreement to purchase from REMIC I all the Mortgage Loans and all property
acquired in respect of any Mortgage Loan at a price determined as provided in
the Agreement. The exercise of such right will effect early retirement of the
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Loans at the time of purchase being less than
10% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-off Date.

            The recitals contained herein shall be taken as statements of the
Depositor and the Trustee assumes no responsibility for their correctness.

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

                                     A-16-5

            IN WITNESS WHEREOF, the Trustee has caused this Certificate to be
duly executed.

form of Exhibit G to the Agreement, unless the Trustee is provided with an

of ERISA or Section 4975 of the Code (or comparable provisions of any subsequent
enactments) and will not subject the Depositor, the Servicer, the Trustee or the
Trust Fund to any obligation or liability (including obligations or liabilities
under ERISA or Section 4975 of the Code) in addition to those undertaken in the
Agreement, which Opinion of Counsel shall not be an expense of the Depositor,
the Servicer, the Trustee or the Trust Fund.

            If this Certificate or any interest therein is acquired or held in
violation of the provisions of Section 5.02(c) of the Agreement, the next
preceding permitted beneficial owner will be treated as the beneficial owner of
this Certificate retroactive to the date of transfer to the purported beneficial
owner. Any purported beneficial owner whose acquisition or holding of any this
Certificate or any interest therein was effected in violation of the provisions
of Section 5.02(c) of the Agreement shall indemnify and hold harmless the
Depositor, the Servicer, the Trustee and the Trust Fund from and against any and
all liabilities, claims, costs or expenses incurred by those parties as a result
of that acquisition or holding.

            The Certificates are issuable in fully registered form only without
coupons in Classes and denominations representing Percentage Interests specified
in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, the Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.
No service charge will be made for any such registration of transfer or exchange
of Certificates, but the Trustee may require payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection
with any transfer or exchange of Certificates.

            Prior to registration of any transfer, sale or other disposition of
this Certificate, the proposed transferee shall provide to the Trustee (i) an
affidavit to the effect that such transferee is any Person other than a
Disqualified Organization or the agent (including a broker, nominee or
middleman) of a Disqualified Organization, and (ii) a certificate that
acknowledges that (A) the

                                     A-17-5

Class R Certificates have been designated as a residual interest in a REMIC, (B)
it will include in its income a pro rata share of the net income of the Trust
Fund and that such income may be an "excess inclusion," as defined in the Code,
that, with certain exceptions, cannot be offset by other losses or benefits from
any tax exemption, and (C) it expects to have the financial means to satisfy all
of its tax obligations including those relating to holding the Class R
Certificates. Notwithstanding the registration in the Certificate Register of
any transfer, sale or other disposition of this Certificate to a Disqualified
Organization or an agent (including a broker, nominee or middleman) of a
Disqualified Organization, such registration shall be deemed to be of no legal
force or effect whatsoever and such Person shall not be deemed to be a
Certificateholder for any purpose, including, but not limited to, the receipt of
distributions in respect of this Certificate.

            The Holder of this Certificate, by its acceptance hereof, shall be
deemed to have consented to the provisions of Section 5.02 of the Agreement and
to any amendment of the Agreement deemed necessary by counsel of the Depositor
to ensure that the transfer of this Certificate to any Person other than a
Permitted Transferee or any other Person will not cause the Trust Fund to cease
to qualify as a REMIC or cause the imposition of a tax upon the REMIC.

            The Depositor, the Servicer, the Trustee and any agent of the
Depositor, the Servicer or the Trustee may treat the Person in whose name this
Certificate is registered as the owner hereof for all purposes, and none of the
Depositor, the Servicer, the Trustee nor any such agent shall be affected by
notice to the contrary.

            The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts
held by the Trustee and required to be paid to them pursuant to the Agreement
following the earlier of (i) the final payment or other liquidation (or any
advance with respect thereto) of the last Mortgage Loan and REO Property
remaining in REMIC I and (ii) the purchase by the party designated in the
Agreement at a price determined as provided in the Agreement from REMIC I of all
the Mortgage Loans and all property acquired in respect of such Mortgage Loans.
The Agreement permits, but does not require, the party designated in the
Agreement to purchase from REMIC I all the Mortgage Loans and all property
acquired in respect of any Mortgage Loan at a price determined as provided in
the Agreement. The exercise of such right will effect early retirement of the
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Loans at the time of purchase being less than
10% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-off Date.

            The recitals contained herein shall be taken as statements of the
Depositor and the Trustee assumes no responsibility for their correctness.

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

                                     A-17-6

            IN WITNESS WHEREOF, the Trustee has caused this Certificate to be
duly executed.

as follows:

            The Transferee is a "qualified institutional buyer" as that term is

Certificates for its own account or for the account of a qualified institutional
buyer, and understands that such Certificate may be resold, pledged or
transferred only (i) to a person reasonably believed to be a qualified
institutional buyer that purchases for its own account or for the account of a
qualified institutional buyer to whom notice is given that the resale, pledge or
transfer is being made in reliance on Rule 144A, or (ii) pursuant to another
exemption from registration under the 1933 Act.

            2.    The Transferee has been furnished with all information
regarding (a) the Certificates and distributions thereon, (b) the nature,
performance and servicing of the Mortgage Loans, (c) the Pooling and Servicing
Agreement referred to below, and (d) any credit enhancement mechanism associated
with the Certificates, that it has requested.

            All capitalized terms used but not otherwise defined herein have the

Depositor, Option One Mortgage Corporation as Servicer and Wells Fargo Bank,

                                     Name:
                                     Title:

                                      F-1-3

            QUALIFIED INSTITUTIONAL BUYER STATUS UNDER SEC RULE 144A

          [For Transferees Other Than Registered Investment Companies]

            The undersigned hereby certifies as follows to [name of Transferor]

marked below.

which is attached hereto.

      ___ SAVINGS AND LOAN. The Transferee (a) is a savings and loan

primary and predominant business activity is the writing of insurance or the
reinsuring of risks underwritten by insurance companies and which is subject to
supervision by the insurance commissioner or a similar official or agency of a
State, territory or the District of Columbia.

      ___ STATE OR LOCAL PLAN. The Transferee is a plan established and
maintained by a State, its political subdivisions, or any agency or
instrumentality of the State or its political subdivisions, for the benefit of
its employees.

      ___ ERISA PLAN. The Transferee is an employee benefit plan within the
meaning of Title I of the Employee Retirement Income Security Act of 1974.

            4.    For purposes of determining the aggregate amount of securities
owned and/or invested on a discretionary basis by the Transferee, the Transferee
used the cost of such securities to the Transferee and did not include any of
the securities referred to in the preceding paragraph. Further, in determining
such aggregate amount, the Transferee may have included securities owned by
subsidiaries of the Transferee, but only if such subsidiaries are consolidated
with the Transferee in its financial statements prepared in accordance with
generally accepted accounting principles and if the investments of such
subsidiaries are managed under the Transferee's direction. However, such
securities were not included if the Transferee is a majority-owned, consolidated
subsidiary of another enterprise and the Transferee is not itself a reporting
company under the Securities Exchange Act of 1934.

Transferee agrees that, in connection with any purchase of securities sold to
the Transferee for the account of a third party (including any separate account)
in reliance on Rule 144A, the Transferee will only purchase for the account of a
third party that at the time is a "qualified institutional buyer" within the
meaning of Rule 144A. In addition, the Transferee agrees that the Transferee
will not purchase securities for a third party unless the Transferee has
obtained a current representation letter from such third party or taken other
appropriate steps contemplated by Rule 144A to

                                     F-1-5

conclude that such third party independently meets the definition of "qualified
institutional buyer" set forth in Rule 144A.

            7.    The Transferee will notify each of the parties to which this
certification is made of any changes in the information and conclusions herein.
Until such notice is given, the Transferee's purchase of the Certificates will
constitute a reaffirmation of this certification as of the date of such
purchase. In addition, if the Transferee is a bank or savings and loan as
provided above, the Transferee agrees that it will furnish to such parties
updated annual financial statements promptly after they become available.

adviser (the "Adviser").

            2.    In connection with purchases by the Transferee, the Transferee

            3.    The term "FAMILY OF INVESTMENT COMPANIES" as used herein means
two or more registered investment companies (or series thereof) that have the
same investment adviser or investment advisers that are affiliated (by virtue of

            6.    The undersigned will notify the parties to which this
certification is made of any changes in the information and conclusions herein.

STATE OF NEW YORK      )

COUNTY OF NEW YORK     )

            __________________________, being duly sworn, deposes, represents
and warrants as follows:

            1.    I am a ______________________ of ____________________________
(the "Owner") a corporation duly organized and existing under the laws of
______________, the record owner of Carrington Mortgage Loan Trust, Series
2006-OPT1 Asset-Backed Pass-Through Certificates, Class R-I Certificates and the
Class R-II, (the "Class R Certificates"), on behalf of whom I make this
affidavit and agreement. Capitalized terms used but not defined herein have the
respective meanings assigned thereto in the Pooling and Servicing Agreement
pursuant to which the Class R Certificates were issued.

            2.    The Owner (i) is and will be a "Permitted Transferee" as of
____________, 20__ and (ii) is acquiring the Class R Certificates for its own
account or for the account of another Owner from which it has received an
affidavit in substantially the same form as this affidavit. A "Permitted
Transferee" is any person other than a "disqualified organization" or a
possession of the United States. For this purpose, a "disqualified organization"
means the United States, any state or political subdivision thereof, any agency
or instrumentality of any of the foregoing (other than an instrumentality all of
the activities of which are subject to tax and, except for the Federal Home Loan
Mortgage Corporation, a majority of whose board of directors is not selected by
any such governmental entity) or any foreign government, international
organization or any agency or instrumentality of such foreign government or
organization, any rural electric or telephone cooperative, or any organization
(other than certain farmers' cooperatives) that is generally exempt from federal
income tax unless such organization is subject to the tax on unrelated business
taxable income.

            3.    The Owner either (i) is not a Plan, any Person acting,
directly or indirectly, on behalf of any such Plan or any Person acquiring the
Class R Certificates with "plan assets" of a Plan (within the meaning of the
Department of Labor regulation promulgated at 29 C. F. R. ss. 2510.3-101), or
(ii) has provided the Trustee with an Opinion of Counsel acceptable to and in
form and substance satisfactory to the Depositor, the Trustee and the Servicer
to the effect that the purchase and holding of the Class R Certificates are
permissible under applicable law, will not constitute or result in any
non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of
the Code (or comparable provisions of any subsequent enactments) and will not
subject the Depositor, the Servicer, the Trustee or the Trust Fund to any
obligation or liability (including obligations or liabilities under ERISA or
Section 4975 of the Code) in addition to those undertaken in the Pooling and
Servicing Agreement, which Opinion of Counsel shall not be an expense of the
Depositor, the Servicer, the Trustee or the Trust Fund.

                                      F-2-1

            4.    The Owner is aware (i) of the tax that would be imposed on
transfers of the Class R Certificates to disqualified organizations under the
Internal Revenue Code of 1986 that applies to all transfers of the Class R
Certificates after March 31, 1988; (ii) that such tax would be on the transferor
or, if such transfer is through an agent (which person includes a broker,
nominee or middleman) for a non-Permitted Transferee, on the agent; (iii) that
the person otherwise liable for the tax shall be relieved of liability for the
tax if the transferee furnishes to such person an affidavit that the transferee
is a Permitted Transferee and, at the time of transfer, such person does not
have actual knowledge that the affidavit is false; and (iv) that each of the
Class R Certificates may be a "noneconomic residual interest" within the meaning
of proposed Treasury regulations promulgated under the Code and that the
transferor of a "noneconomic residual interest" will remain liable for any taxes
due with respect to the income on such residual interest, unless no significant
purpose of the transfer is to impede the assessment or collection of tax.

            5.    The Owner is aware of the tax imposed on a "pass-through
entity" holding the Class R Certificates if, at any time during the taxable year
of the pass-through entity, a non-Permitted Transferee is the record holder of
an interest in such entity. (For this purpose, a "pass-through entity" includes
a regulated investment company, a real estate investment trust or common trust
fund, a partnership, trust or estate, and certain cooperatives.)

            6.    The Owner is aware that the Trustee will not register the
transfer of any Class R Certificate unless the transferee, or the transferee's
agent, delivers to the Trustee, among other things, an affidavit in
substantially the same form as this affidavit. The Owner expressly agrees that
it will not consummate any such transfer if it knows or believes that any of the
representations contained in such affidavit and agreement are false.

            7.    The Owner consents to any additional restrictions or
arrangements that shall be deemed necessary upon advice of counsel to constitute
a reasonable arrangement to ensure that the Class R Certificates will only be
owned, directly or indirectly, by an Owner that is a Permitted Transferee.

            8.    The Owner's taxpayer identification number is _______________.

            9.    The Owner has reviewed the restrictions set forth on the face
of the Class R Certificates and the provisions of Section 5.02(d) of the Pooling
and Servicing Agreement under which the Class R Certificates were issued (in
particular, clauses (iii)(A) and (iii)(B) of Section 5.02(d) which authorize the
Trustee to deliver payments to a person other than the Owner and negotiate a
mandatory sale by the Trustee in the event that the Owner holds such Certificate
in violation of Section 5.02(d)); and that the Owner expressly agrees to be
bound by and to comply with such restrictions and provisions.

            10.   The Owner is not acquiring and will not transfer the Class R
Certificates in order to impede the assessment or collection of any tax.

            11.   The Owner anticipates that it will, so long as it holds the
Class R Certificates, have sufficient assets to pay any taxes owed by the holder
of such Class R Certificates, and hereby represents to and for the benefit of
the person from whom it acquired the

                                     F-2-2

Class R Certificates that the Owner intends to pay taxes associated with holding
such Class R Certificates as they become due, fully understanding that it may
incur tax liabilities in excess of any cash flows generated by the Class R
Certificates.

            12.   The Owner has no present knowledge that it may become
insolvent or subject to a bankruptcy proceeding for so long as it holds the
Class R Certificates.

            13.   The Owner has no present knowledge or expectation that it will
be unable to pay any United States taxes owed by it so long as any of the
Certificates remain outstanding.

            14.   The Owner is not acquiring the Class R Certificates with the
intent to transfer the Class R Certificates to any person or entity that will
not have sufficient assets to pay any taxes owed by the holder of such Class R
Certificates, or that may become insolvent or subject to a bankruptcy
proceeding, for so long as the Class R Certificates remain outstanding.

            15.   The Owner will, in connection with any transfer that it makes
of the Class R Certificates, obtain from its transferee the representations
required by Section 5.02(d) of the Pooling and Servicing Agreement under which
the Class R Certificate were issued and will not consummate any such transfer if
it knows, or knows facts that should lead it to believe, that any such
representations are false.

            16.   The Owner will, in connection with any transfer that it makes
of the Class R Certificates, deliver to the Trustee an affidavit, which
represents and warrants that it is not transferring the Class R Certificates to
impede the assessment or collection of any tax and that it has no actual
knowledge that the proposed transferee: (i) has insufficient assets to pay any
taxes owed by such transferee as holder of the Class R Certificates; (ii) may
become insolvent or subject to a bankruptcy proceeding for so long as the Class
R Certificates remains outstanding; and (iii) is not a "Permitted Transferee".

            17.   The Owner is a citizen or resident of the United States, a
corporation, partnership or other entity created or organized in, or under the
laws of, the United States or any political subdivision thereof, or an estate or
trust whose income from sources without the United States may be included in
gross income for United States federal income tax purposes regardless of its
connection with the conduct of a trade or business within the United States.

            18.   The Owner of the Class R Certificate, hereby agrees that in
the event that the Trust Fund created by the Pooling and Servicing Agreement is
terminated pursuant to Section 9.01 thereof, the undersigned shall assign and
transfer to the Holders of the Class CE Certificates (with respect to a
termination of REMIC I) any amounts in excess of par received in connection with
such termination. Accordingly, in the event of such termination, the Trustee is

            __________________________, being duly sworn, deposes, represents
and warrants as follows:

            1.    I am a ____________________ of ____________________________
(the "Owner"), a corporation duly organized and existing under the laws of
______________, on behalf of whom I make this affidavit.

            2.    The Owner is not transferring the Class R Certificates (the
"Residual Certificates") to impede the assessment or collection of any tax.

            3.    The Owner has no actual knowledge that the Person that is the
proposed transferee (the "Purchaser") of the Residual Certificates: (i) has
insufficient assets to pay any taxes owed by such proposed transferee as holder
of the Residual Certificates; (ii) may become insolvent or subject to a
bankruptcy proceeding for so long as the Residual Certificates remain
outstanding and (iii) is not a Permitted Transferee.

            4.    The Owner understands that the Purchaser has delivered to the
Trustee a transfer affidavit and agreement in the form attached to the Pooling
and Servicing Agreement as Exhibit F-2. The Owner does not know or believe that
any representation contained therein is false.

            5.    At the time of transfer, the Owner has conducted a reasonable
investigation of the financial condition of the Purchaser as contemplated by
Treasury Regulations Section 1.860E-1(c)(4)(i) and, as a result of that
investigation, the Owner has determined that the Purchaser has historically paid
its debts as they became due and has found no significant evidence to indicate
that the Purchaser will not continue to pay its debts as they become due in the
future. The Owner understands that the transfer of a Residual Certificate may
not be respected for United States income tax purposes (and the Owner may
continue to be liable for United States income taxes associated therewith)
unless the Owner has conducted such an investigation.

            6.    Capitalized terms not otherwise defined herein shall have the
meanings ascribed to them in the Pooling and Servicing Agreement.

              PERFECTION REPRESENTATIONS, WARRANTIES AND COVENANTS

      The Depositor hereby represents, warrants, and covenants as follows on the
Closing Date and on each Distribution Date thereafter:

   General

            1.    This Agreement creates a valid and continuing security
interest (as defined in the applicable Uniform Commercial Code ("UCC")) in the
Mortgage Loans in favor of the Trustee which security interest is prior to all
other liens, and is enforceable as such as against creditors of and purchasers
from the Depositor.

            2.    The Mortgage Loans constitute "general intangibles" or
"instruments" within the meaning of the applicable UCC.

            3.    The Custodial Account and all subaccounts thereof constitute
either a deposit account or a securities account.

            4.    To the extent that payments and collections received or made
with respect to the Mortgage Loans constitute securities entitlements, such
payments and collections have been and will have been credited to the Custodial
Account. The securities intermediary for the Custodial Account has agreed to
treat all assets credited to the Custodial Account as "financial assets" within
the meaning of the applicable UCC.

   Creation

            5.    The Depositor owns and has good and marketable title to the
Mortgage Loans free and clear of any lien, claim or encumbrance of any Person,
excepting only liens for taxes, assessments or similar governmental charges or
levies incurred in the ordinary course of business that are not yet due and
payable or as to which any applicable grace period shall not have expired, or
that are being contested in good faith by proper proceedings and for which
adequate reserves have been established, but only so long as foreclosure with
respect to such a lien is not imminent and the use and value of the property to
which the lien attaches is not impaired during the pendency of such proceeding.

            6.    The Depositor has received all consents and approvals to the
transfer of the Mortgage Loans hereunder to the Trustee required by the terms of
the Mortgage Loans that constitute instruments.

            7.    To the extent the Custodial Account or subaccounts thereof
constitute securities entitlements, certificated securities or uncertificated
securities, the Depositor has received all consents and approvals required to
transfer to the Trustee its interest and rights in the Custodial Account
hereunder.

                                  Schedule 3-1

   Perfection

            8.    The Depositor has caused or will have caused, within ten days
after the effective date of this Agreement, the filing of all appropriate
financing statements in the proper filing office in the appropriate
jurisdictions under applicable law in order to perfect the transfer of the
Mortgage Loans from the Depositor to the Trustee and the security interest in
the Mortgage Loans granted to the Trustee hereunder.

            9.    With respect to the Custodial Account and all subaccounts that
constitute deposit accounts, either:

            (i)   the Depositor has delivered to the Trustee a fully-executed
      agreement pursuant to which the bank maintaining the deposit accounts has
      agreed to comply with all instructions originated by the Trustee directing
      disposition of the funds in the Custodial Account without further consent
      by the Depositor; or

            (ii)  the Depositor has taken all steps necessary to cause the
      Trustee to become the account holder of the Custodial Account.

            10.   With respect to the Custodial Account or subaccounts thereof
that constitute securities accounts or securities entitlements, the Depositor
has caused or will have caused, within ten days after the effective date of this
Agreement, the filing of all appropriate financing statements in the proper
filing office in the appropriate jurisdictions under applicable law in order to
perfect the security interest in the Custodial Account granted by the Depositor
to the Trustee.

   Priority

            11.   Other than the transfer of the Mortgage Loans to the Trustee
pursuant to this Agreement, the Depositor has not pledged, assigned, sold,
granted a security interest in, or otherwise conveyed any of the Mortgage Loans.
The Depositor has not authorized the filing of, or is not aware of any financing
statements against the Depositor that include a description of collateral
covering the Mortgage Loans other than any financing statement relating to the
security interest granted to the Trustee hereunder or that has been terminated.

            12.   The Depositor is not aware of any judgment, ERISA or tax lien
filings against the Depositor.

            13.   The Trustee has in its possession all original copies of the
Mortgage Notes that constitute or evidence the Mortgage Loans. To the
Depositor's knowledge, none of the instruments that constitute or evidence the
Mortgage Loans has any marks or notations indicating that they have been
pledged, assigned or otherwise conveyed to any Person other than the Trustee or
its designee. All financing statements filed or to be filed against the
Depositor in favor of the Trustee in connection herewith describing the Mortgage
Loans contain a statement to the following effect: "A purchase of or security
interest in any collateral described in this financing statement will violate
the rights of the Trustee."

                                  Schedule 3-2

            14.   Neither the Custodial Account nor any subaccount thereof is in
the name of any person other than the Depositor or the Trustee or in the name of
its nominee. The Depositor has not consented for the securities intermediary of
the Custodial Account to comply with entitlement orders of any person other than
the Trustee or its designee.

            15.   Survival of Perfection Representations. Notwithstanding any
other provision of this Agreement or any other transaction document, the
Perfection Representations contained in this Schedule shall be continuing, and
remain in full force and effect (notwithstanding any replacement of the Servicer
or termination of the Servicer's rights to act as such) until such time as all
obligations under this Agreement have been finally and fully paid and performed.

            16.   No Waiver. The parties to this Agreement (i) shall not,
without obtaining a confirmation of the then-current rating of the Certificates
waive any of the Perfection Representations, and (ii) shall provide the Rating
Agencies with prompt written notice of any breach of the Perfection
Representations, and shall not, without obtaining a confirmation of the
then-current rating of the Certificates (as determined after any adjustment or
withdrawal of the ratings following notice of such breach) waive a breach of any
of the Perfection Representations.

            17.   Depositor to Maintain Perfection and Priority. The Depositor
covenants that, in order to evidence the interests of the Depositor and the
Trustee under this Agreement, the Depositor shall take such action, or execute
and deliver such instruments (other than effecting a Filing (as defined below),
unless such Filing is effected in accordance with this paragraph) as may be
necessary or advisable (including, without limitation, such actions as are
requested by the Trustee) to maintain and perfect, as a first priority interest,
the Trustee's security interest in the Mortgage Loans. The Depositor shall, from
time to time and within the time limits established by law, prepare and present
to the Purchaser or its designee to authorize (based in reliance on the Opinion
of Counsel hereinafter provided for) the Depositor to file, all financing
statements, amendments, continuations, initial financing statements in lieu of a
continuation statement, terminations, partial terminations, releases or partial
releases, or any other filings necessary or advisable to continue, maintain and
perfect the Trustee's security interest in the Mortgage Loans as a
first-priority interest (each a "Filing"). The Depositor shall present each such
Filing to the Trustee or its designee together with (x) an Opinion of Counsel to
the effect that such Filing is (i) consistent with the grant of the security
interest to the Trustee pursuant to Section 11.09 of this Agreement, (ii)
satisfies all requirements and conditions to such Filing in this Agreement and
(iii) satisfies the requirements for a Filing of such type under the Uniform
Commercial Code in the applicable jurisdiction (or if the Uniform Commercial
Code does not apply, the applicable statute governing the perfection of security
interests), and (y) a form of authorization for the Trustee's signature. Upon
receipt of such Opinion of Counsel and form of authorization, the Trustee shall
promptly authorize in writing the Depositor to, and the Depositor shall, effect
such Filing under the UCC without the signature of the Depositor or the Trustee
where allowed by applicable law. Notwithstanding anything else in the
transaction documents to the contrary, the Depositor shall not have any
authority to effect a Filing without obtaining written authorization from the
Trustee or its designee.
