                  This Pooling and Servicing Agreement is dated as of January 1,

the Trust Fund created hereunder. The Certificates will consist of eighteen
classes of certificates, designated as (i) the Class A-1A Certificates, (ii) the
Class A-1B Certificates, (iii) the Class A-2 Certificates, (iv) the Class A-3
Certificates, (v) the Class A-4 Certificates, (vi) the Class M-1 Certificates,
(vii) the Class M-2 Certificates, (viii) the Class M-3 Certificates, (ix) the

                  As provided herein, the Trustee will make an election to treat

Agreement (but exclusive of the Pre-Funding Accounts, the Net WAC Rate Carryover
Reserve Account, the Master Servicer Prepayment Charge Payment Amounts and the
Cap Contracts) as a real estate investment conduit (a "REMIC") for federal
income tax purposes, and such segregated pool of assets will be designated as

guarantee certain payments of notes issued pursuant to an Indenture and (ii) any
series of notes issued pursuant to one or more Indentures remain outstanding or
the NIMS Insurer is owed amounts in respect of its guarantee of payment on such

(except pursuant to Section 11.01 in the case of clause (ii) below) so long as
(i) the NIMS Insurer has not undertaken to guarantee certain payments of notes
issued pursuant to the Indenture or (ii) any default has occurred and is
continuing under the insurance policy issued by the NIMS Insurer with respect to
such notes.

                          CONVEYANCE OF MORTGAGE LOANS;
                        ORIGINAL ISSUANCE OF CERTIFICATES

                  SECTION 2.01.     Conveyance of Mortgage Loans.

                  The Depositor, concurrently with the execution and delivery
hereof, does hereby transfer, assign, set over and otherwise convey in trust to
the Trustee without recourse for the 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 (i) each Mortgage Loan
identified on the Mortgage Loan Schedule, including the related Cut-off Date
Principal Balance, all interest accruing thereon on and after the Cut-off Date
and all collections in respect of interest and principal due after the Cut-off
Date; (ii) property which secured each such Mortgage Loan and which has been
acquired by foreclosure or deed in lieu of foreclosure; (iii) its interest in
any insurance policies (including the PMI Policy) in respect of the Mortgage
Loans; (iv) the rights of the Depositor under the Mortgage Loan Purchase
Agreement, (v) all other assets included or to be included in the Trust Fund,
(vi) [reserved] and (vii) all proceeds of any of the foregoing. Such assignment
includes all interest and principal due and collected by the Depositor or the
Master Servicer after the Cut-off Date with respect to the Mortgage Loans.

                  In connection with such transfer and assignment, the
Depositor, does hereby deliver to, and deposit with the Trustee, or its
designated agent (the "Custodian"), the following documents or instruments with
respect to each Initial Mortgage Loan so transferred and assigned and the
Originator, on behalf of the Depositor, shall, in accordance with Section 2.08,
deliver or caused to be delivered to the Trustee with respect to each Subsequent
Mortgage Loan, the following documents or instruments (a "Mortgage File") with
respect to each Mortgage Loan so transferred and assigned:

                  (i)      the original Mortgage Note, endorsed either (A) in
         blank, in which case the Trustee shall cause the endorsement to be
         completed or (B) in the following form: "Pay to the order of Wells
         Fargo Bank, N.A., as Trustee, without recourse", or with respect to any
         lost Mortgage Note, an original Lost Note Affidavit stating that the
         original mortgage note was lost, misplaced or destroyed, together with
         a copy of the related mortgage note; PROVIDED, HOWEVER, that such
         substitutions of Lost Note Affidavits for original Mortgage Notes may
         occur only with respect to Mortgage Loans, the aggregate Cut-off Date
         Principal Balance or Subsequent Cut-off Date Principal Balance, as
         applicable, of which is less than or equal to 1.00% of the Pool Balance
         as of the Cut-off Date or Subsequent Cut-off Date, as applicable;

                  (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. The Mortgage shall be
         assigned either (A) in blank or (B) to "Wells Fargo Bank, N.A., as
         Trustee, without recourse";


                                       56
<PAGE>


                  (iv)     an original of any intervening assignment of Mortgage
         showing a complete chain of assignments;

                  (v)      the original or a certified copy of lender's title
         insurance policy; and

                  (vi)     the original or copies of each assumption,
         modification, written assurance or substitution agreement, if any.

                  The Trustee agrees to execute and deliver (or cause the
Custodian to execute and deliver) to the Depositor and the NIMS Insurer on or
prior to the Closing Date an acknowledgment of receipt of the original Mortgage
Note (with any exceptions noted), substantially in the form attached as Exhibit
F-3 hereto.

                  If any of the documents referred to in Section 2.01(ii), (iii)
or (iv) above has as of the Closing Date (or Subsequent Transfer Date, with
respect to Subsequent Mortgage Loans) 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 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 or the Custodian no
later than the Closing Date (or Subsequent Closing Date, with respect to
Subsequent Mortgage Loans), of a copy of each such document certified by the
Master Servicer, in its capacity as 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 Master Servicer, in its capacity as Originator,
delivery to the Trustee or the Custodian, 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. If the
original lender's title insurance policy, or a certified copy thereof, was not
delivered pursuant to Section 2.01(v) above, the Master Servicer, in its
capacity as Originator, shall deliver or cause to be delivered to the Trustee or
the Custodian, the original or a copy of a written commitment or interim binder
or preliminary report of title issued by the title insurance or escrow company
or an original attorney's opinion of title, with the original or a certified
copy thereof to be delivered to the Trustee or the Custodian, promptly upon
receipt thereof. The Master Servicer or the Depositor shall deliver or cause to
be delivered to the Trustee or the Custodian promptly upon receipt thereof any
other 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.

                  Upon discovery or receipt of notice of any materially
defective document in, or that a document is missing from, a Mortgage File, the
Master Servicer, in its capacity as Originator, shall have 120 days to cure such
defect or deliver such missing document to the Trustee or the Custodian. If the
Originator does not cure such defect or deliver such missing document within
such time period, the Master Servicer, in its capacity as Originator, shall
either repurchase or substitute for such Mortgage Loan in accordance with
Section 2.03.

                  The Depositor (at the expense of the Master Servicer, in its
capacity as Originator) shall cause the Assignments which were delivered in
blank to be completed and shall cause all Assignments referred to in Section
2.01(iii) hereof and, to the extent necessary, in Section 2.01(iv) hereof to be
recorded. The Depositor shall be required to deliver such


                                       57
<PAGE>


Assignments for recording within 90 days of the Closing Date (or Subsequent
Transfer Date, with respect to a Subsequent Mortgage Loan). Notwithstanding the
foregoing, however, for administrative convenience and facilitation of servicing
and to reduce closing costs, the Assignments of Mortgage shall not be required
to be submitted for recording (except with respect to any Mortgage Loan located
in Maryland) unless the Trustee and the Depositor receive notice that such
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, each
Assignment shall be submitted for recording by the Depositor in the manner
described above, at no expense to the Trust Fund or 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 Master Servicer Event
of Termination, (iii) the occurrence of a bankruptcy, insolvency or foreclosure
relating to the Master Servicer, (iv) the occurrence of a servicing transfer as
described in Section 7.02 hereof, (v) if the Originator is not the Master
Servicer and with respect to any one Assignment the occurrence of a bankruptcy,
insolvency or foreclosure relating to the Mortgagor under the related Mortgage,
(vi) any Mortgage Loan that is 90 days or more Delinquent and such recordation
would be necessary to facilitate conversion of the Mortgaged Property in
accordance with Section 3.16 and (vii) reasonable direction by the NIMS Insurer.
Upon (a) receipt of written notice from the Trustee that recording of the
Assignments is required pursuant to one or more of the conditions (excluding (v)
and (vi) above) set forth in the preceding sentence or (b) upon the occurrence
of condition (v) or (vi) in the preceding sentence, the Depositor shall be
required to deliver such Assignments for recording as provided above, promptly
and in any event within 30 days following receipt of such notice.
Notwithstanding the foregoing, if the Originator fails to pay the cost of
recording the Assignments, such expense will be paid by the Trustee and the
Trustee shall be reimbursed for such expenses by the Trust. To the extent not
previously delivered to the Trustee by the Depositor, the Depositor shall
furnish the Trustee, or its designated agent, with a copy of each Assignment
submitted for recording. In the event that any such Assignment is lost or
returned unrecorded because of a defect therein, the Depositor shall promptly
have a substitute Assignment prepared or have such defect cured, as the case may
be, and thereafter cause each such Assignment to be duly recorded.

                  The Depositor herewith delivers to the Trustee an executed
copy of each Mortgage Loan Purchase Agreement and the PMI Policy.

                  The Master Servicer shall forward to the Custodian original
documents evidencing an assumption, modification, consolidation or extension of
any Mortgage Loan entered into in accordance with this Agreement within two
weeks of their execution; provided, however, that the Master Servicer shall
provide the Custodian with a certified true copy of any such document submitted
for recordation within two weeks of its execution, and shall provide the
original of any document submitted for recordation or a copy of such document
certified by the appropriate public recording office to be a true and complete
copy of the original within 365 days of its submission for recordation. In the
event that the Master Servicer cannot provide a copy of such document certified
by the public recording office within such 365 day period, an Officers'
Certificate of the Master Servicer which shall (A) identify the recorded
document, (B) state that the recorded document has not been delivered to the
Custodian due solely to a delay caused by the public recording office, (C) state
the amount of time generally required by the applicable recording office to
record and return a document submitted for recordation, if known and (D) specify
the date the applicable recorded document is expected to be delivered to the
Custodian, and, upon receipt of a copy of such document certified by the public
recording office,


                                       58
<PAGE>


the Master Servicer shall immediately deliver such document to the Custodian. In
the event the appropriate public recording office will not certify as to the
accuracy of such document, the Master Servicer shall deliver a copy of such
document certified by an officer of the Master Servicer to be a true and
complete copy of the original to the Custodian.

                  The parties hereto understand and agree that it is not
intended that any mortgage loan be included in the Trust that is a "High-Cost
Home Loan" as defined by the HOEPA or any other applicable predatory or abusive
lending laws.

                  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 Certificates. The Seller, the
Depositor, the Master Servicer and the Holders of the 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 2.02.     Acceptance by Trustee.

                  Subject to the provisions of Section 2.01 and subject to the
review described below and any exceptions noted on the exception report
described in the next paragraph below, the Trustee acknowledges receipt of the
documents referred to in Section 2.01 above and all other assets included in the
definition of "Trust Fund" 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 "Trust Fund" 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, or that it has reviewed pursuant to Section 2.01 (or to cause the
Custodian to review or that it has caused the Custodian to have reviewed) each
Mortgage File on or prior to the Closing Date, with respect to each Initial
Mortgage Loan or the Subsequent Transfer Date, with respect to each Subsequent
Mortgage Loan (or, with respect to any document delivered after the Startup Day,
within 45 days of receipt and with respect to any Qualified Substitute Mortgage,
within 45 days after the assignment thereof). The Trustee further agrees, for
the benefit of the Certificateholders, to certify to the Depositor, the Master
Servicer and the NIMS Insurer in substantially the form attached hereto as
Exhibit F-1, within 45 days after the Closing Date, with respect to each Initial
Mortgage Loan and the Subsequent Transfer Date, with respect to each Subsequent
Mortgage Loan (or, with respect to any document delivered after the Startup Day,
within 45 days of receipt and with respect to any Qualified Substitute Mortgage,
within 45 days after the assignment thereof) 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 required
to be delivered to it pursuant Section 2.01 of this Agreement are in its
possession, (ii) such documents have been reviewed by it and have not been
mutilated, damaged or torn 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 (1) and (2) of the Mortgage
Loan Schedule accurately reflects information set forth in the Mortgage File. It
is herein acknowledged that, in conducting such review, the Trustee (or the
Custodian, as applicable) is under no duty or obligation to inspect, review or
examine any such documents, instruments,


                                       59
<PAGE>


certificates or other papers to determine that they are genuine, enforceable, or
appropriate for the represented purpose or that they have actually been recorded
or that they are other than what they purport to be on their face.

                  Prior to the first anniversary date of this Agreement the
Trustee shall deliver (or cause the Custodian to deliver) to the Depositor, the
Master Servicer and the NIMS Insurer a final certification in the form annexed
hereto as Exhibit F-2 evidencing the completeness of the Mortgage Files, with
any applicable exceptions noted thereon.

                  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 (or the Custodian, as applicable) 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 Originator the Depositor, the NIMS Insurer and the Master Servicer. In
addition, upon the discovery by the Originator, the Depositor, the NIMS Insurer
or the Master Servicer (or upon receipt by the Trustee of written notification
of such breach) of a breach of any of the representations and warranties made by
the Originator in the Mortgage Loan Purchase Agreement in respect of any
Mortgage Loan which materially adversely affects such Mortgage Loan or the
interests of the related Certificateholders in such Mortgage Loan, the party
discovering such breach shall give prompt written notice to the other parties to
this Agreement.

                  The Depositor and the Trustee intend that the assignment and
transfer herein contemplated constitute 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 Originator.

                  (a)      Upon discovery or receipt of written notice of any
materially defective document in, or that a document is missing from, a Mortgage
File or of the breach by the Originator of any representation, warranty or
covenant under the Mortgage Loan Purchase Agreement in respect of any Mortgage
Loan which materially adversely affects the value of such Mortgage Loan or the
interest therein of the Certificateholders, the Trustee shall promptly notify
the Originator, the NIMS Insurer and the Master Servicer of such defect, missing
document or breach and request that the Originator deliver such missing document
or cure such defect or breach within 120 days from the date the Originator was
notified of such missing document, defect or breach, and if the Originator does
not deliver such missing document or cure such defect or breach in all material
respects during such period, the Trustee shall enforce the Originator's
obligation under the Mortgage Loan Purchase Agreement and cause the Originator
to repurchase such Mortgage Loan from the Trust Fund at the Purchase Price on or
prior to the Determination Date following the expiration of such 120 day period
(subject to Section 2.03(e)).


                                       60
<PAGE>


The Purchase Price for the repurchased Mortgage Loan shall be deposited in the
Collection Account, and the Trustee, upon receipt of written certification from
the Master Servicer of such deposit, shall release to the Originator the related
Mortgage File and shall execute and deliver such instruments of transfer or
assignment, in each case without recourse, as the Originator shall furnish to it
and as shall be necessary to vest in the Originator any Mortgage Loan released
pursuant hereto and the Trustee shall have no further responsibility with regard
to such Mortgage File (it being understood that the Trustee shall have no
responsibility for determining the sufficiency of such assignment for its
intended purpose). In lieu of repurchasing any such Mortgage Loan as provided
above, the Originator may cause such Mortgage Loan to be removed from the Trust
Fund (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(d). It is understood and agreed that the
obligation of the Originator 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 against the Originator respecting
such omission, defect or breach available to the Trustee on behalf of the
Certificateholders.

                  (b)      Within 90 days of the earlier of discovery by the
Depositor or receipt of notice by the Depositor of the breach of any
representation, warranty or covenant of the Depositor set forth in Section 2.06
which materially and adversely affects the interests of the Certificateholders
in any Mortgage Loan, the Depositor shall cure such breach in all material
respects.

                  (c)      Within 90 days of the earlier of discovery by the
Master Servicer or receipt of notice by the Master Servicer of the breach of any
representation, warranty or covenant of the Master Servicer set forth in Section
2.05 which materially and adversely affects the interests of the
Certificateholders in any Mortgage Loan, the Master Servicer shall cure such
breach in all material respects.

                  (d)      Any substitution of Qualified Substitute Mortgage
Loans for Deleted Mortgage Loans made pursuant to Section 2.03(a) must be
effected prior to the last Business Day that is within two years after the
Closing Date. As to any Deleted Mortgage Loan for which the Originator
substitutes a Qualified Substitute Mortgage Loan or Loans, such substitution
shall be effected by the Originator delivering to the Trustee, for such
Qualified Substitute Mortgage Loan or Loans, the Mortgage Note, the Mortgage and
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 Adjustment
(as described below), if any, in connection with such substitution. 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 Master Servicer and the NIMS
Insurer, with respect to such Qualified Substitute Mortgage Loan or Loans, a
certification substantially in the form attached hereto as Exhibit F-1, with any
applicable exceptions noted thereon. Within one year of the date of
substitution, the Trustee shall deliver to the Master Servicer and the NIMS
Insurer a certification substantially in the form of Exhibit F-2 hereto 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 the Trust
Fund and will be


                                       61
<PAGE>


retained by the Originator. For the month of substitution, distributions to
Certificateholders will reflect the collections and recoveries in respect of
such Deleted Mortgage Loan in the Due Period preceding the month of substitution
and the Originator shall thereafter be entitled to retain all amounts
subsequently received in respect of such Deleted Mortgage Loan. The Originator
shall give or cause to be given written notice to the Certificateholders and the
NIMS Insurer that such substitution has taken place, shall amend the Mortgage
Loan Schedule to reflect the removal of such Deleted Mortgage Loan from the
terms of this Agreement and the substitution of the Qualified Substitute
Mortgage Loan or Loans and shall deliver a copy of such amended Mortgage Loan
Schedule to the NIMS Insurer and the Trustee. Upon such substitution by the
Originator, 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 as of the date of substitution.

                  For any month in which the Originator substitutes one or more
Qualified Substitute Mortgage Loans for one or more Deleted Mortgage Loans, the
Master Servicer will determine the amount (the "Substitution Adjustment"), if
any, by which the aggregate Purchase Price of all such Deleted Mortgage Loans
exceeds the aggregate, as to each such Qualified Substitute Mortgage Loan, of
the principal balance thereof as of the date of substitution, together with one
month's interest on such principal balance at the applicable Net Mortgage Rate.
On the date of such substitution, the Originator will deliver or cause to be
delivered to the Master Servicer for deposit in the Collection Account an amount
equal to the Substitution Adjustment, if any, and the Trustee, upon receipt of
the related Qualified Substitute Mortgage Loan or Loans and certification by the
Master Servicer of such deposit, shall release to the Originator the related
Mortgage File or Files and shall execute and deliver such instruments of
transfer or assignment, in each case without recourse, as the Originator shall
deliver to it and as shall be necessary to vest therein any Deleted Mortgage
Loan released pursuant hereto.

                  In addition, the Originator shall obtain at its own expense
and deliver to the Trustee and the NIMS Insurer an Opinion of Counsel to the
effect that such substitution will not cause (a) any federal tax to be imposed
on the Trust Fund, including without limitation, any federal tax imposed on
"prohibited transactions" under Section 860F(a)(l) of the Code or on
"contributions after the startup date" under Section 860G(d)(l) of the Code or
(b) any REMIC to fail to qualify as a REMIC at any time that any Certificate is
outstanding. If such Opinion of Counsel can not be delivered, then such
substitution may only be effected at such time as the required Opinion of
Counsel can be given.

                  Upon discovery by the Originator, the Master Servicer, the
NIMS Insurer 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 Originator or the
Depositor, as the case may be, shall repurchase or, subject to the limitations
set forth in Section 2.03(d), 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 (i) by the Originator 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 Originator under
the Mortgage Loan Purchase Agreement or (ii) the Depositor, if the affected
Mortgage Loan's status as a non-


                                       62
<PAGE>


qualified mortgage is a breach of any representation or warranty of the
Depositor set forth in Section 2.06, or if its 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),
if made by the Originator, or Section 2.03(b), if made by the Depositor. The
Trustee shall reconvey to the Depositor or the Originator, as the case may be,
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.     Intentionally Omitted.

                  SECTION 2.05.     Representations, Warranties and Covenants of
                                    the Master Servicer.

                  The Master Servicer hereby represents, warrants and covenants
to the Trustee, for the benefit of each of the Trustee and the
Certificateholders and to the Depositor that as of the Closing Date or as of
such date specifically provided herein:

                  (i)      The Master 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 Master Servicer or to ensure the
         enforceability or validity of each Mortgage Loan; the Master 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 Master 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 Master 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 Master Servicer to
         make this Agreement valid and binding upon the Master 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 Master
         Servicer and will not result in the breach of any term or provision of
         the charter or by-laws of the Master 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 Master Servicer or its property is subject, or result in the
         violation of any law, rule, regulation, order, judgment or decree to
         which the Master Servicer or its property is subject;

                  (iii)    The execution and delivery of this Agreement by the
         Master 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;


                                       63
<PAGE>


                  (iv)     This Agreement, and all documents and instruments
         contemplated hereby which are executed and delivered by the Master
         Servicer, constitute and will constitute valid, legal and binding
         obligations of the Master 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)      [Reserved];

                  (vi)     The Master 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 Master 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 Master Servicer that might prohibit or materially and
         adversely affect the performance by such Master 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 Master Servicer to carry on its business substantially as now
         conducted, or (C) may result in any material liability on the part of
         the Master 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 Master Servicer contemplated
         herein, or (E) would otherwise be likely to impair materially the
         ability of the Master Servicer to perform under the terms of this
         Agreement;

                  (viii)   Neither this Agreement nor any information,
         certificate of an officer, statement furnished in writing or report
         delivered to the Trustee by the Master Servicer in connection with the
         transactions contemplated hereby contains any untrue statement of a
         material fact;

                  (ix)     The Master Servicer covenants that its computer and
         other systems used in servicing the Mortgage Loans operate in a manner
         such that the Master Servicer can service the Mortgage Loans in
         accordance with the terms of this Agreement;

                  (x)      The information set forth in the Prepayment Charge
         Schedule (including the Prepayment Charge Summary attached thereto) is
         complete, true and correct in all material respects on the date or
         dates when such information is furnished and each Prepayment Charge is
         permissible and enforceable in accordance with its terms (except to the
         extent that the enforceability thereof may be limited by bankruptcy,
         insolvency, moratorium, receivership and other similar laws affecting
         creditor's rights generally or the collectibility thereof may be
         limited due to acceleration in connection with a foreclosure) under
         applicable federal, state and local law;

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

                  (xii)    The Master Servicer has accurately and fully
         reported, and will continue to accurately and fully report, its
         borrower credit files to each of the credit repositories in a timely
         manner.

                  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 NIMS Insurer, the Master Servicer, the Originator 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,
Prepayment Charge 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 Master Servicer, the
Originator, the NIMS Insurer and the Trustee. Notwithstanding the foregoing,
within 90 days of the earlier of discovery by the Master Servicer or receipt of
notice by the Master Servicer of the breach of the representation or covenant of
the Master Servicer (in its capacity as Originator) set forth in Sections
2.05(x) or 2.05(xi) above which materially and adversely affects the interests
of the Holders of the Class P Certificates in any Prepayment Charge, the Master
Servicer shall remedy such breach as follows: (a) if the representation made by
the Master Servicer (in its capacity as Originator) in Section 2.05(x) above is
breached and a Principal Prepayment has occurred in the applicable Prepayment
Period or if a change of law subsequent to the Closing Date limits the
enforceability of a Prepayment Charge (other than in the circumstances provided
in Section 2.05(x) above), the Master Servicer (in its capacity as Originator)
must pay the amount of the scheduled Prepayment Charge, for the benefit of the
Holders of the Class P Certificates, by depositing such amount into the
Collection Account, net of any amount previously collected by the Master
Servicer and paid by the Master Servicer, for the benefit of the Holders of the
Class P Certificates, in respect of such Prepayment Charge; and (b) if any of
the covenants made by the Master Servicer in Section 2.05(xi) above is breached,
the Master Servicer must 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 Collection Account. The foregoing shall not, however, limit any
remedies available to the Certificateholders, the Depositor or the Trustee on
behalf of the Certificateholders, pursuant to the Mortgage Loan Purchase
Agreement signed by the Master Servicer in its capacity as Originator,
respecting a breach of the representations, warranties and covenants of the
Master Servicer in its capacity as Originator contained in the Mortgage Loan
Purchase Agreement.

                  SECTION 2.06.     Representations and Warranties of the
                                    Depositor.

                  The Depositor represents and warrants to the Trust and the
Trustee on behalf of the Certificateholders as follows:

                  (i)      This Agreement constitutes a legal, valid and binding
         obligation of the Depositor, enforceable against the Depositor in
         accordance with its terms, except as enforceability may be limited by
         applicable bankruptcy, insolvency, reorganization, moratorium or other
         similar laws now or hereafter in effect affecting the enforcement of
         creditors' rights in general and except as such enforceability may be
         limited by general principles of equity (whether considered in a
         proceeding at law or in equity);

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


                                       65
<PAGE>


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

                  (iv)     The Depositor has not transferred the Mortgage Loans
         to the Trustee on behalf of the Trust with any intent to hinder, delay
         or defraud any of its creditors;

                  (v)      The Depositor has been duly incorporated and is
         validly existing as a corporation in good standing under the laws of
         Delaware, with full corporate power and authority to own its assets and
         conduct its business as presently being conducted;

                  (vi)     The Depositor is not in violation of its articles of
         incorporation or by-laws or in default in the performance or observance
         of any material obligation, agreement, covenant or condition contained
         in any contract, indenture, mortgage, loan agreement, note, lease or
         other instrument to which the Depositor is a party or by which it or
         its properties may be bound, which default might result in any material
         adverse changes in the financial condition, earnings, affairs or
         business of the Depositor or which might materially and adversely
         affect the properties or assets, taken as a whole, of the Depositor;

                  (vii)    The execution, delivery and performance of this
         Agreement by the Depositor, and the consummation of the transactions
         contemplated thereby, do not and will not result in a material breach
         or violation of any of the terms or provisions of, or, to the knowledge
         of the Depositor, constitute a default under, any indenture, mortgage,
         deed of trust, loan agreement or other agreement or instrument to which
         the Depositor is a party or by which the Depositor is bound or to which
         any of the property or assets of the Depositor is subject, nor will
         such actions result in any violation of the provisions of the articles
         of incorporation or by-laws of the Depositor or, to the best of the
         Depositor's knowledge without independent investigation, any statute or
         any order, rule or regulation of any court or governmental agency or
         body having jurisdiction over the Depositor or any of its properties or
         assets (except for such conflicts, breaches, violations and defaults as
         would not have a material adverse effect on the ability of the
         Depositor to perform its obligations under this Agreement);

                  (viii)   To the best of the Depositor's knowledge without any
         independent investigation, no consent, approval, authorization, order,
         registration or qualification of or with any court or governmental
         agency or body of the United States or any other jurisdiction is
         required for the issuance of the Certificates, or the consummation by
         the Depositor of the other transactions contemplated by this Agreement,
         except such consents, approvals, authorizations, registrations or
         qualifications as (a) may be required under State securities or Blue
         Sky laws, (b) have been previously obtained or (c) the failure of which
         to obtain would not have a material adverse effect on the performance
         by the Depositor of its obligations under, or the validity or
         enforceability of, this Agreement; and

                  (ix)     There are no actions, proceedings or investigations
         pending before or, to the Depositor's knowledge, threatened by any
         court, administrative agency or other tribunal to which the Depositor
         is a party or of which any of its properties is the subject: (a) which
         if determined adversely to the Depositor would have a material adverse
         effect


                                       66
<PAGE>


         on the business, results of operations or financial condition of the
         Depositor; (b) asserting the invalidity of this Agreement or the
         Certificates; (c) seeking to prevent the issuance of the Certificates
         or the consummation by the Depositor of any of the transactions
         contemplated by this Agreement, as the case may be; or (d) which might
         materially and adversely affect the performance by the Depositor of its
         obligations under, or the validity or enforceability of, this
         Agreement.

                  SECTION 2.07.     Issuance of Certificates.

                  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
Sections 2.01 and 2.02, together with the assignment to it of all other assets
included in the Trust Fund, 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 Certificates in authorized denominations. The interests
evidenced by the Certificates, constitute the entire beneficial ownership
interest in the Trust Fund.

                  SECTION 2.08.     Conveyance of the Subsequent Mortgage Loans.

                  (a)      Subject to the conditions set forth in paragraph (b)
below in consideration of the Trustee's delivery on the Subsequent Transfer
Dates to or upon the order of the Depositor of all or a portion of the balance
of funds in the Pre-Funding Accounts, the Depositor shall on any Subsequent
Transfer Date sell, transfer, assign, set over and convey without recourse to
the Trust Fund but subject to the other terms and provisions of this Agreement
all of the right, title and interest of the Depositor in and to (i) the
Subsequent Mortgage Loans identified on the Mortgage Loan Schedule attached to
the related Subsequent Transfer Instrument delivered by the Depositor on such
Subsequent Transfer Date, (ii) all interest accruing thereon on and after the
Subsequent Cut-off Date and all collections in respect of interest and principal
due after the Subsequent Cut-off Date and (iii) all items with respect to such
Subsequent Mortgage Loans to be delivered pursuant to Section 2.01 and the other
items in the related Mortgage Files; PROVIDED, HOWEVER, that the Depositor
reserves and retains all right, title and interest in and to principal received
and interest accruing on the Subsequent Mortgage Loans prior to the related
Subsequent Cut-off Date. The transfer to the Trustee for deposit in the Mortgage
Pool by the Depositor of the Subsequent Mortgage Loans identified on the
Mortgage Loan Schedule shall be absolute and is intended by the Depositor, the
Master Servicer, the Trustee and the Certificateholders to constitute and to be
treated as a sale of the Subsequent Mortgage Loans by the Depositor to the Trust
Fund. The related Mortgage File for each Subsequent Mortgage Loan shall be
delivered to the Trustee at least three Business Days prior to the related
Subsequent Transfer Date.

                  The purchase price paid by the Trustee from amounts released
from the Group I Pre-Funding Account or the Group II Pre-Funding Account, as
applicable, shall be one-hundred percent (100%) of the aggregate Stated
Principal Balance of the related Subsequent Mortgage Loans so transferred (as
identified on the Mortgage Loan Schedule provided by the Depositor). This
Agreement shall constitute a fixed-price purchase contract in accordance with
Section 860G(a)(3)(A)(ii) of the Code.

property and rights related thereto as described in paragraph (a) above, and the
Trustee shall release funds from the Group I Pre-Funding Account or the Group II
Pre-Funding Account, as applicable, only upon the satisfaction of each of the

                  (vi)     the Depositor shall not have selected the Subsequent

                  (x)      the Depositor shall have received the consent of the

                          ADMINISTRATION AND SERVICING
                              OF THE MORTGAGE LOANS

                  SECTION 3.01.     Master Servicer to Act as Master Servicer.

                  The Master Servicer shall service and administer the Mortgage
Loans on behalf of the Trust and in the best interests of and for the benefit of
the Certificateholders (as determined by the Master Servicer in its reasonable
judgment) in accordance with the terms of this Agreement and the 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, giving
due consideration to customary and usual standards of practice of mortgage
lenders and loan servicers administering similar mortgage loans but without
regard to:

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

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

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

                  (D)      the Master 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 Master
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 and (ii)
either (A) such waiver relates to a default or a reasonably foreseeable default
and would, in the reasonable judgement of the Master Servicer, maximize recovery
of total proceeds taking into account the value of such Prepayment Charge and
the related Mortgage Loan or (B) such waiver is made in connection with a
refinancing of the related Mortgage Loan unrelated to a default or a reasonably
foreseeable default where (x) the related Mortgagor has stated to the Master
Servicer or an applicable Sub-Servicer an intention to refinance the related
Mortgage Loan and (y) the Master Servicer has concluded in its reasonable
judgement that the waiver of such Prepayment Charge would induce such mortgagor
to refinance with the Master Servicer; provided, however, that the Master
Servicer shall waive no more than 5.00% of the Prepayment Charges (by number of
Prepayment Charges) set forth on the Prepayment Charge Schedule in accordance
with clause (ii)(B) above. If a Prepayment Charge is waived as permitted by
meeting the standards described in clauses (i) and (ii)(B) above, then the
Master Servicer is 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 Collection Account together with and at the time that the amount
prepaid on the related Mortgage Loan is required to be deposited into the
Collection Account. Notwithstanding any other provisions of this Agreement, any
payments


                                       73
<PAGE>


made by the Master Servicer in respect of any waived Prepayment Charges pursuant
to clauses (i) and (ii)(B) 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 Mortgage Loans, the Master 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 Master Servicer in its own
name or in the name of a Sub-Servicer is hereby authorized and empowered by the
Trustee when the Master Servicer believes it appropriate in its best judgment in
accordance with the servicing standards set forth above, to execute and deliver,
on behalf of the Certificateholders and the Trustee, and upon 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 Master 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 Master 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,
within 15 days of the Closing Date, the Trustee shall execute, at the written
request of the Master Servicer, and furnish to the Master Servicer and any
Sub-Servicer any special or limited powers of attorney for each county in which
a Mortgaged Property is located and other documents necessary or appropriate to
enable the Master Servicer or any Sub-Servicer to carry out their servicing and
administrative duties hereunder; PROVIDED, such limited powers of attorney or
other documents shall be prepared by the Master Servicer and submitted to the
Trustee for execution. The Trustee shall not be liable for the actions of the
Master 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 Master Servicer shall advance or cause
to be advanced funds as necessary for the purpose of effecting the payment of
taxes and assessments on the Mortgaged Properties, which advances shall be
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 Master Servicer or by Sub-Servicers in effecting
the 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 Master Servicer may not make any future advances with respect to a Mortgage
Loan (except as provided in Section 4.04) and the Master 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 Master 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


                                       74
<PAGE>


any REMIC created hereunder 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.

                  SECTION 3.02.     Sub-Servicing Agreements Between Master
                                    Servicer and Sub-Servicers.

                  (a)      The Master Servicer may enter into Sub-Servicing
Agreements with Sub-Servicers for the servicing and administration of the
Mortgage Loans; PROVIDED, HOWEVER, that (i) such agreements would not result in
a withdrawal or a downgrading by any Rating Agency of the rating on any Class of
Certificates and (ii) the NIMS Insurer shall have consented to such
Sub-Servicing Agreement. The Trustee is hereby authorized to acknowledge, at the
request of the Master Servicer, any Sub-Servicing Agreement that 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 Master 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 Master 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 Master Servicer, are conclusively deemed to be inconsistent
with this Agreement and therefore prohibited. The Master Servicer shall deliver
to the NIMS Insurer and the Trustee copies of all Sub-Servicing Agreements, and
any amendments or modifications thereof, promptly upon the Master Servicer's
execution and delivery of such instruments.

                  (b)      As part of its servicing activities hereunder, the
Master Servicer, for the benefit of the Trustee and the Certificateholders,
shall enforce the obligations of each Sub-Servicer under the related
Sub-Servicing Agreement and of the Originator under the Mortgage


                                       75
<PAGE>


Loan Purchase Agreement, including, without limitation, any obligation 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-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 Master Servicer, in
its good faith business judgment, would require were it the owner of the related
Mortgage Loans. The Master Servicer shall pay the costs of such enforcement at
its own expense, and shall be reimbursed therefor 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. Enforcement of the Mortgage
Loan Purchase Agreement against the Originator shall be effected by the Master
Servicer to the extent it is not the Originator, and otherwise by the Trustee in
accordance with the foregoing provisions of this paragraph.

                  SECTION 3.03.     Successor Sub-Servicers.

                  The Master Servicer, with the consent of the NIMS Insurer,
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 Master Servicer without any
act or deed on the part of such Sub-Servicer or the Master Servicer, and the
Master 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 Master Servicer or the
Trustee (if the Trustee is acting as Master Servicer) without fee, in accordance
with the terms of this Agreement, in the event that the Master Servicer (or the
Trustee, if such party is then acting as Master Servicer) shall, for any reason,
no longer be the Master Servicer (including termination due to a Master Servicer
Event of Termination).

                  SECTION 3.04.     Liability of the Master Servicer.

                  Notwithstanding any Sub-Servicing Agreement or the provisions
of this Agreement relating to agreements or arrangements between the Master
Servicer and a Sub-Servicer or reference to actions taken through a Sub-Servicer
or otherwise, the Master 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 Master
Servicer alone were servicing and administering the Mortgage Loans. The Master
Servicer shall be entitled to enter into any agreement with a Sub-Servicer for
indemnification of the Master 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 and the NIMS Insurer, the
                                    Trustee or Certificateholders.

                  Any Sub-Servicing Agreement that may be entered into and any
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
Master Servicer alone, and the NIMS Insurer, the Trustee or 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 Master Servicer shall be solely liable for all
fees owed by it to any Sub-Servicer, irrespective of whether the Master
Servicer's compensation pursuant to this Agreement is sufficient to pay such
fees.

                  SECTION 3.06.     Assumption or Termination of Sub-Servicing
                                    Agreements by Trustee.

                  In the event the Master Servicer shall for any reason no
longer be the servicer (including by reason of the occurrence of a Master
Servicer Event of Termination), the Trustee shall thereupon assume all of the
rights and obligations of the Master Servicer under each Sub-Servicing Agreement
that the Master Servicer may have entered into, unless the Trustee elects to
terminate any Sub-Servicing Agreement in accordance with its terms as provided
in Section 3.03. Upon such assumption, the Trustee (or the successor servicer
appointed pursuant to Section 7.02) shall be deemed, subject to Section 3.03, to
have assumed all of the departing Master Servicer's interest therein and to have
replaced the departing Master 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 departing Master Servicer
shall not thereby be relieved of any liability or obligations under any
Sub-Servicing Agreement that arose before it ceased to be the Master Servicer
and (ii) neither the Trustee nor any successor Master Servicer shall be deemed
to have assumed any liability or obligation of the Master Servicer that arose
before it ceased to be the Master Servicer.

                  The Master Servicer at its expense shall, upon request of
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 the
Sub-Servicing Agreements to the assuming party. All Servicing Transfer Costs
shall be paid by the predecessor Master Servicer upon presentation of reasonable
documentation of such costs, and if such predecessor Master Servicer defaults in
its obligation to pay such costs, such costs shall be paid by the successor
Master Servicer or the Trustee (in which case the successor Master Servicer or
the Trustee, as applicable, shall be entitled to reimbursement therefor from the
assets of the Trust).

                  SECTION 3.07.     Collection of Certain Mortgage Loan
                                    Payments.

                  The Master 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


                                       77

with the foregoing, the Master 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 Master Servicer shall
make timely Advances on such Mortgage Loan during such extension pursuant to
Section 4.04 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 Master Servicer, such default is
reasonably foreseeable, the Master Servicer, consistent with the standards set
forth in Section 3.01, may also waive, modify or vary any term of such Mortgage
Loan (including modifications that would change the Mortgage Rate, forgive the
payment of principal or interest, capitalize the interest portion of 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, 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 Master 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, PROVIDED, FURTHER,
that in determining which course of action permitted by this sentence it shall
pursue, the Master Servicer shall adhere to the Loss Mitigation Procedures and
PROVIDED, FURTHER, that the NIMS Insurer's prior written consent shall be
required for any modification, waiver or amendment if the aggregate number of
outstanding Mortgage Loans which have been modified, waived or amended exceeds
5% of the number of Mortgage Loans as of the Cut-off Date and any Subsequent
Cut-off Date. The Master Servicer's analysis supporting any forbearance and the
conclusion that any forbearance meets the standards of Section 3.01 and the Loss
Mitigation Procedures 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 Collection
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 Collection Account or remit such
proceeds to the Master Servicer for deposit in the Collection Account not later
than two Business Days after the deposit of such


                                       78
<PAGE>


amounts in the Sub-Servicing Account. For purposes of this Agreement, the Master
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 Master Servicer shall establish and maintain, or cause to
be established and maintained, one or more accounts (the "Servicing Accounts"),
into which all Escrow Payments shall be deposited and retained. Servicing
Accounts shall be Eligible Accounts. The Master 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 Master
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 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 Master Servicer (or a Sub-Servicer to the extent
provided in the related Sub-Servicing Agreement) out of related collections for
any Servicing 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 to
the Master Servicer or, 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 Master Servicer's obligations and
responsibilities in respect of the Mortgage Loans under this Agreement in
accordance with Article X. In the event the Master 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 Master 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 Master Servicer knows, or in
the exercise of the required standard of care of the Master 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 Master Servicer receives notice of a tax lien with respect
to the Mortgage being imposed, the Master 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 Master
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
Master 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.     Collection Account and Distribution Account.

                  (a)      On behalf of the Trust Fund, the Master Servicer
shall establish and maintain, or cause to be established and maintained, one or
more accounts (such account or accounts, the "Collection Account"), held in
trust for the benefit of the Trustee and the Certificateholders. On behalf of
the Trust Fund, the Master 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 Master
Servicer's receipt thereof, and shall thereafter deposit in the Collection
Account, in no event more than two Business Days after the Master 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 or Subsequent Cut-off Date, as applicable, (other than in respect
of principal or interest on the Mortgage Loans due on or before the Cut-off Date
or Subsequent Cut-off Date, as applicable) or payments (other than Principal
Prepayments) received by it on or prior to the Cut-off Date or Subsequent
Cut-off Date, as applicable, 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;

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

                  (iii)    all Insurance Proceeds, Liquidation Proceeds,
         Subsequent Recoveries and condemnation 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 10.01);

                  (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 Collection Account;

                  (v)      any amounts required to be deposited by the Master
         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 or Section 10.01;

                  (vii)    all amounts required to be deposited in connection
         with Substitution Adjustments pursuant to Section 2.03;

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

                  (ix)     without duplication, all payments of claims under the
         PMI Policy.

                  The foregoing requirements for deposit in the Collection
Account shall be exclusive, it being understood and agreed that, without
limiting the generality of the foregoing,


                                       80
<PAGE>


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 Master Servicer in the Collection Account and may
be retained by the Master Servicer as additional compensation. In the event the
Master Servicer shall deposit in the Collection Account any amount not required
to be deposited therein, it may at any time withdraw such amount from the
Collection 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
"Distribution Account"), held in trust for the benefit of the Trustee and the
Certificateholders. On behalf of the Trust Fund, the Master Servicer shall
deliver to the Trustee in immediately available funds for deposit in the
Distribution Account on or before 1:00 p.m. New York time (i) on the Master
Servicer Remittance Date, that portion of the Available Funds (calculated
without regard to the references in the definition thereof to amounts that may
be withdrawn from the Distribution Account) for the related Distribution Date
then on deposit in the Collection Account, the amount of all Prepayment Charges
collected during the applicable Prepayment Period by the Master Servicer and
Master Servicer Prepayment Charge Payment Amounts in connection with the
Principal Prepayment of any of the Mortgage Loans then on deposit in the
Collection Account and the amount of any funds reimbursable to an Advancing
Person pursuant to Section 3.29, and (ii) on each Business Day as of the
commencement of which the balance on deposit in the Collection Account exceeds
$75,000 following any withdrawals pursuant to the next succeeding sentence, the
amount of such excess, but only if the Collection Account constitutes an
Eligible Account solely pursuant to clause (ii) of the definition of "Eligible
Account." If the balance on deposit in the Collection Account exceeds $75,000 as
of the commencement of business on any Business Day and the Collection Account
constitutes an Eligible Account solely pursuant to clause (ii) of the definition
of "Eligible Account," the Master Servicer shall, on or before 1:00 p.m. New
York time on such Business Day, withdraw from the Collection Account any and all
amounts payable or reimbursable to the Master Servicer, the Trustee, the
Originator or any Sub-Servicer pursuant to Section 3.11 and shall pay such
amounts to the Persons entitled thereto.

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

                  (d)      Funds held in the Collection Account at any time may
be delivered by the Master Servicer to the Trustee for deposit in an account
(which may be the Distribution Account and must satisfy the standards for the
Distribution Account as set forth in the definition thereof) and for all
purposes of this Agreement shall be deemed to be a part of the Collection
Account; PROVIDED, HOWEVER, that the Trustee shall have the sole authority to
withdraw any funds held pursuant to this subsection (d). In the event the Master
Servicer shall deliver to the Trustee for deposit in the Distribution Account
any amount not required to be deposited therein, it may at any time request that
the Trustee withdraw such amount from the Distribution Account and remit to it
any such amount, any provision herein to the contrary notwithstanding. In
addition, the Master Servicer, with respect to items (i) through (iv) below,
shall deliver to the Trustee from


                                       81
<PAGE>


time to time for deposit, and the Trustee, with respect to items (i) through
(iv) below, shall so deposit, in the Distribution Account:

                  (i)      any Advances, as required pursuant to Section 4.04;

                  (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 10.01;

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

                  (v)      any amounts required to be paid to the Trustee
         pursuant to the Agreement, including, but not limited to Section 3.06
         and Section 7.02.

                  (e)      [Reserved].

                  (f)      The Master Servicer shall deposit in the Collection
Account any amounts required to be deposited pursuant to Section 3.12(b) in
connection with losses realized on Permitted Investments with respect to funds
held in the Collection Account.

                  SECTION 3.11.     Withdrawals from the Collection Account and
                                    Distribution Account.

                  (a)      The Master Servicer shall, from time to time, make
withdrawals from the Collection Account for any of the following purposes or as
described in Section 4.04:

                  (i)      to remit to the Trustee for deposit in the
         Distribution 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 Master
         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 or Liquidation Proceeds and Insurance
         Proceeds on Mortgage Loans with respect to which such Advances were
         made in accordance with the provisions of Section 4.04; (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, including, Liquidation Proceeds and Insurance
         Proceeds received with respect to such Mortgage Loan are insufficient
         to reimburse the Master Servicer for such unreimbursed Advances; or (c)
         subject to Section 4.04(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 Master
         Servicer or any Sub-Servicer (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, including,


                                       82
<PAGE>


         Liquidation Proceeds, Insurance Proceeds and condemnation proceeds
         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, including, Liquidation Proceeds and Insurance Proceeds
         received with respect to such Mortgage Loan are insufficient to
         reimburse the Master Servicer or any Sub-Servicer for Servicing
         Advances;

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

                  (v)      to pay to the Originator, 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 Master Servicer for any Advance or
         Servicing Advance previously made which the Master Servicer has
         determined to be a Nonrecoverable Advance in accordance with the
         provisions of Section 4.04;

                  (vii)    to pay, or to reimburse the Master 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 Master Servicer for expenses
         incurred by or reimbursable to the Master Servicer pursuant to Section
         6.03;

                  (ix)     to reimburse the NIMS Insurer, the Master Servicer
         (if the Master 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 any Prepayment Interest Excess; and

                  (xi)     to clear and terminate the Collection Account
         pursuant to Section 10.01.

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

                  The Master Servicer shall keep and maintain separate
accounting, on a Mortgage Loan by Mortgage Loan basis, for the purpose of
justifying any withdrawal from the Collection Account, to the extent held by or
on behalf of it, pursuant to subclauses (ii), (iii), (v), (vi), (ix) and (x)
above. The Master Servicer shall provide written notification to the NIMS
Insurer and the Trustee, on or prior to the next succeeding Master Servicer
Remittance Date, upon making any withdrawals from the Collection Account
pursuant to subclause (vi) above; PROVIDED that an


                                       83
<PAGE>


Officers' Certificate in the form described under Section 4.04(d) shall suffice
for such written notification to the Trustee in respect hereof.

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

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

                  (ii)     to pay itself the Trustee Fee and any other amounts
         owed to it pursuant to Section 8.05;

                  (iii)    to pay any amounts in respect of taxes pursuant to
         Section 9.01(g);

                  (iv)     to clear and terminate the Distribution Account
         pursuant to Section 10.01;

                  (v)      to pay any amounts required to be paid to the Trustee
         pursuant to this Agreement, including but not limited to funds required
         to be paid pursuant to Section 3.06 and Section 7.02;

                  (vi)     to pay to the Trustee, any interest or investment
         income earned on funds deposited in the Distribution Account;

                  (vii)    to pay to an Advancing Person reimbursements for
         Advances and/or Servicing Advances pursuant to Section 3.29; and

                  (viii)   to pay the PMI Insurer the PMI Premium.

                  SECTION 3.12.     Investment of Funds in the Collection
                                    Account and the Distribution Account.

                  (a)      The Master Servicer may direct any depository
institution maintaining the Collection Account to invest the funds on deposit in
such accounts, and the Trustee may invest the funds on deposit in the
Distribution Account (each such account, for the purposes of this Section 3.12
an "Investment Account"). All investments pursuant to this Section 3.12 shall be
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 or if such investment is managed or advised by a Person
other than the Trustee or an Affiliate of the Trustee, 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 or if such
investment is managed or advised by the Trustee or any Affiliate. 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 (in its capacity as such), or in the name of a nominee of the Trustee.
The Trustee shall be entitled to sole possession (except with respect to
investment direction of funds held in the Collection 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


                                       84
<PAGE>


Account are at any time invested in a Permitted Investment payable on demand,
the Trustee 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 Collection Account and any REO Account held by or on
behalf of the Master Servicer shall be for the benefit of the Master Servicer
and shall be subject to its withdrawal in accordance with Section 3.11 or
Section 3.23, as applicable. The Master Servicer shall deposit in the Collection
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
account immediately upon realization of such loss.

                  (c)      All income and gain realized from the investment of
funds deposited in the Distribution Account shall be for the benefit of the
Trustee. The Trustee shall deposit in the Distribution Account 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.

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

                  SECTION 3.13.     [Reserved].

                  SECTION 3.14.     Maintenance of Hazard Insurance and Errors
                                    and Omissions and Fidelity Coverage.

                  (a)      The Master Servicer shall cause to be maintained for
each Mortgage Loan hazard insurance with extended coverage on the Mortgaged
Property in an amount which is at least equal to the lesser of (i) the current
Principal Balance of such Mortgage Loan and (ii) 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 Master Servicer shall also
cause to be maintained hazard insurance


                                       85
<PAGE>


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 Master 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 Master 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 Master 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 Collection 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 Master 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 Master 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 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 Master Servicer shall obtain and
maintain a blanket policy with an insurer having a General Policy Rating of
B:III 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
Master 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 Collection 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 Master 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 Master 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 Master 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, unless the Master Servicer has obtained a
waiver of such requirements from Fannie Mae or Freddie Mac. The Master Servicer
shall provide the Trustee


                                       86
<PAGE>


and the NIMS Insurer, upon request, with copies of such insurance policies and
fidelity bond. The Master Servicer shall also maintain a fidelity bond in the
form and amount that would meet the requirements of Fannie Mae or Freddie Mac,
unless the Master Servicer has obtained a waiver of such requirements from
Fannie Mae or Freddie Mac. The Master Servicer shall be deemed to have complied
with this provision if an Affiliate of the Master 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 Master
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
and the NIMS Insurer. The Master 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 Master 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 Master Servicer shall not be required to take such action if
in its sole business judgment the Master 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 Master 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
Master 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 Master 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 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 Master Servicer and has a credit risk rating at least equal to
that of the original Mortgagor. In connection with any assumption or
substitution, the Master Servicer shall apply such 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 Master 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 Master Servicer in respect of an assumption, modification or substitution of
liability agreement shall be retained by the Master 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 Master 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


                                       87
<PAGE>


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 Master 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 Master 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 Master Servicer shall use its best efforts, in as
practical a time frame as possible and consistent with Servicing Standard, 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 Master 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 Master Servicer as contemplated in Section 3.11 and Section 3.23. The
foregoing is subject to the provision that, in any case in which a Mortgaged
Property shall have suffered damage from an Uninsured Cause, the Master 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 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 Master 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 Master Servicer shall not, on behalf of the
Trustee, 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 Master Servicer has
also previously determined, based on its reasonable judgment and a report
prepared by a 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,


                                       88
<PAGE>


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.

                  Notwithstanding the foregoing, if such environmental audit
reveals, or if the Master Servicer has actual knowledge or notice, that such
Mortgaged Property contains such wastes or substances, the Master Servicer shall
not foreclose or accept a deed in lieu of foreclosure without the prior written
consent of the NIMS Insurer.

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

                  If the Master 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 Master 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
Master Servicer pursuant to this Section 3.16(b) shall constitute Servicing
Advances, subject to Section 4.04(d). The cost of any such compliance,
containment, cleanup or remediation shall be advanced by the Master Servicer,
subject to the Master Servicer's right to be reimbursed therefor from the
Collection Account as provided in Section 3.11(a)(iii) and (a)(vii), such right
of reimbursement being prior to the rights of Certificateholders to receive any
amount in the Collection Account received in respect of the affected Mortgage
Loan or other Mortgage Loans.

                  (c)      (i) The NIMS Insurer may, at its option, purchase a
Mortgage Loan which has become 90 or more days delinquent or for which the
Master Servicer has accepted a deed in lieu of foreclosure. Prior to purchase
pursuant to this Section 3.16(c)(i), the Master Servicer shall be required to
continue to make Advances pursuant to Section 4.04. The NIMS Insurer shall not
use any procedure in selecting Mortgage Loans to be repurchased which is
materially adverse to the interests of the Certificateholders. The NIMS Insurer
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)(i) shall be accomplished by remittance to the Master
Servicer for deposit in the Collection Account of the amount of the Purchase
Price. The Trustee shall immediately effectuate the conveyance of such
delinquent Mortgage Loan to the NIMS Insurer to the extent necessary, including
the prompt delivery of all documentation to the NIMS Insurer.

                  (ii)     If the Master Servicer Optional Purchase Delinquency
         Trigger has been met, the Master Servicer may, at its option, purchase
         a Mortgage Loan which has become 90 or more days delinquent or for
         which the Master Servicer has accepted a deed in lieu of foreclosure.
         Prior to purchase pursuant to this Section 3.16(c)(ii), the Master
         Servicer shall be required to continue to make Advances pursuant to
         Section 4.04. The Master


                                       89
<PAGE>


         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)(ii) shall be
         accomplished by deposit in the Collection Account of the amount of the
         Purchase Price. The Trustee shall immediately effectuate the conveyance
         of such delinquent Mortgage Loan to the Master Servicer to the extent
         necessary, including the prompt delivery of all documentation to the
         Master Servicer.

                  Notwithstanding the foregoing: (A) the Master Servicer shall
have the option to purchase pursuant to this Section 3.16(c)(ii) only such
delinquent Mortgage Loans having an aggregate Stated Principal Balance such
that, if such delinquent Mortgage Loans were not in the Trust, the Master
Servicer Optional Purchase Delinquency Trigger would not be met; (B) if the
Master Servicer purchases any delinquent Mortgage Loans pursuant to this Section
3.16(c)(ii), 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; (C) if the Master Servicer purchases some but not all Mortgage Loans
that are delinquent any given number of days, it must purchase Mortgage Loans
having the same delinquency status in the order of lowest Stated Principal
Balance to highest Stated Principal Balance; (D) the Master Servicer may at any
time relinquish its rights to purchase delinquent Mortgage Loans pursuant to
this Section 3.16(C)(ii) in writing delivered to the Trustee, and from and after
the taking of such action by the Master Servicer, the provisions of this Section
3.16(c)(ii) shall no longer be of any force or effect.

                  (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 condemnation proceeds,
in respect of any Mortgage Loan, will be applied in the following order of
priority: FIRST, to unpaid Servicing Fees; SECOND, to reimburse the Master
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 Master 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 the
receipt by the Master Servicer of a notification that payment in full shall be
escrowed in a manner customary for such purposes, the Master Servicer shall
deliver to the Trustee, in written (with two executed copies) or electronic
format, a Request for Release in the form of Exhibit E (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 Collection Account pursuant to Section 3.10 have been or will be so
deposited) signed by a Servicing Officer (or in a mutually agreeable electronic
format that will, in lieu of a signature on its face, originate from 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 and send by overnight mail, at the expense of the Master Servicer, the
related Mortgage File to the Master Servicer. The Trustee agrees to indemnify
the Master Servicer, out of its own funds, for any loss, liability or expense
(other than special, indirect, punitive or consequential damages which will not
be paid


                                       90
<PAGE>


by the Trustee) incurred by the Master Servicer as a proximate result of the
Trustee's breach of its obligations pursuant to this Section 3.17. No expenses
incurred in connection with any instrument of satisfaction or deed of
reconveyance shall be chargeable to the Collection Account or the Distribution
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 Master Servicer and
delivery to the Trustee, in written (with two executed copies) or electronic
format, of a Request for Release in the form of Exhibit E signed by a Servicing
Officer (or in a mutually agreeable electronic format that will, in lieu of a
signature on its face, originate from a Servicing Officer), release the related
Mortgage File to the Master Servicer within three Business Days, and the Trustee
shall, at the direction of the Master Servicer, execute such documents as shall
be necessary to the prosecution of any such proceedings. Such Request for
Release shall obligate the Master Servicer to return each and every document
previously requested from the Mortgage File to the Trustee when the need
therefor by the Master Servicer no longer exists, unless the Mortgage Loan has
been liquidated and the Liquidation Proceeds relating to the Mortgage Loan have
been deposited in the Collection Account or 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 Master 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 Master 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 Request for Release, in
written (with two executed copies) or electronic format, from 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 Collection Account have been so deposited, or that such
Mortgage Loan has become an REO Property, such Mortgage Loan shall be released
by the Trustee to the Master Servicer or its designee.

                  (c)      Upon written certification of a Servicing Officer,
the Trustee shall execute and deliver to the Master Servicer or the
Sub-Servicer, as the case may be, copies of, 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 Master Servicer
hereunder, the Master 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,


                                       91
<PAGE>


the Master Servicer shall be entitled to recover unpaid Servicing Fees out of
Insurance Proceeds, Liquidation Proceeds or condemnation proceeds 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 Section 3.29, 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 Master Servicer's responsibilities and obligations under this Agreement;
PROVIDED, HOWEVER, that the Master 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 (other than Prepayment Charges) shall be retained by the Master
Servicer only to the extent such fees or charges are received by the Master
Servicer. The Master Servicer shall also be entitled pursuant to Section
3.11(a)(iv) to withdraw from the Collection 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 Master 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 and servicing compensation
of each Sub-Servicer) and shall not be entitled to reimbursement therefor except
as specifically provided herein.

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

                  SECTION 3.19.     Reports to the Trustee; Collection Account
                                    Statements.

                  Not later than twenty days after each Distribution Date, the
Master Servicer shall forward to the NIMS Insurer and, upon request, to the
Trustee and the Depositor the most current available bank statement for the
Collection 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 Master Servicer to
the Trustee.

                  SECTION 3.20.     Statement as to Compliance.

                  The Master Servicer will deliver to the Trustee, the NIMS
Insurer and the Depositor not later than March 10th, commencing in 2006, an
Officers' Certificate substantially in the form of Exhibit S attached hereto
stating, as to each signatory thereof, that (i) a review of the activities of
the Master Servicer during the preceding calendar year and of performance under
this Agreement has been made under such officers' supervision and (ii) to the
best of such officers' knowledge, based on such review, the Master Servicer has
fulfilled all of its obligations under this Agreement throughout such calendar
year, or, if there has been a default in the fulfillment of any such obligation,
specifying each such default known to such officer and the nature and status
thereof. Copies of any 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 Master Servicer to the
Trustee.

                  SECTION 3.21.     Independent Public Accountants' Servicing
                                    Report.

                  Not later than March 10th, commencing in 2006, the Master
Servicer, at its expense, shall cause a nationally recognized firm of
independent certified public accountants to furnish to the Master Servicer a
report stating that (i) it has obtained a letter of representation regarding
certain matters from the management of the Master Servicer which includes an
assertion that the Master Servicer has complied with certain minimum residential
mortgage loan servicing standards, identified in the Uniform Single Attestation
Program for Mortgage Bankers established by the Mortgage Bankers Association of
America, with respect to the servicing of residential mortgage loans during the
most recently completed calendar year and (ii) on the basis of an examination
conducted by such firm in accordance with standards established by the American
Institute of Certified Public Accountants, such representation is fairly stated
in all material respects, subject to such exceptions and other qualifications
that may be appropriate. In rendering its report such firm may rely, as to
matters relating to the direct servicing of residential mortgage loans by
Sub-Servicers, upon comparable reports of firms of independent certified public
accountants rendered on the basis of examinations conducted in accordance with
the same standards (rendered within one year of such report) with respect to
those Sub-Servicers. Immediately upon receipt of such report, the Master
Servicer shall furnish a copy of such report to the Trustee, the NIMS Insurer
and each Rating Agency. Copies of such statement shall be provided by the
Trustee to any Certificateholder upon request at the Master Servicer's expense,
provided that such statement is delivered by the Master Servicer to the Trustee.

                  SECTION 3.22.     Access to Certain Documentation; Filing of
                                    Reports by Trustee.

                  (a)      The Master 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 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 Master Servicer designated by it. In
addition, access to the documentation regarding the Mortgage Loans will be
provided to any Certificateholder or Certificate Owner, the Trustee, the NIMS
Insurer and to any Person identified to the Master Servicer as a prospective
transferee of a Certificate, upon reasonable request during normal business
hours at the offices of the Master Servicer designated by it at the expense of
the Person requesting such access.

                  (b)      The Trustee shall reasonably cooperate with the
Depositor in connection with satisfying the reporting requirements under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"). The Trustee
shall prepare on behalf of the Trust any Forms 8-K and 10-K customary for
similar securities as required by the Exchange Act and the Rules and Regulations
of the Securities and Exchange Commission thereunder, and the Depositor shall
sign and the Trustee shall file (via the Securities and Exchange Commission's
Electronic Data Gathering and Retrieval System) such forms on behalf of the
Depositor. The Depositor hereby grants to the Trustee a limited power of
attorney to execute any Form 8-K and file each such document on behalf of the
Depositor. Such power of attorney shall continue until the earlier of (i)
receipt by the Trustee from the Depositor of written termination of such power
of attorney and (ii) the termination of the Trust. Notwithstanding anything
herein to the contrary, the Depositor,


                                       93
<PAGE>


and not the Trustee, shall be responsible for executing each Form 10-K filed on
behalf of the Trust.

                  (c)      Each Form 8-K shall be filed by the Trustee within 15
days after each Distribution Date, with a copy of the statement to the
Certificateholders for such Distribution Date as an exhibit thereto. Prior to
March 30th of each year, commencing in 2005 (or such earlier date as may be
required by the Exchange Act and the Rules and Regulations of the Securities and
Exchange Commission), the Trustee shall file a Form 10-K, in substance as
required by applicable law or applicable Securities and Exchange Commission
staff's interpretations. Such Form 10-K shall include as exhibits the Master
Servicer's annual statement of compliance described under Section 3.20 and the
accountant's report described under Section 3.21, in each case to the extent
they have been timely delivered to the Trustee. If they are not so timely
delivered, the Trustee shall file an amended Form 10-K including such documents
as exhibits reasonably promptly after they are delivered to the Trustee. The
Trustee shall have no liability with respect to any failure to properly prepare
or file such periodic reports resulting from or relating to the Trustee's
inability or failure to obtain any information not resulting from its own
negligence or willful misconduct. The Form 10-K shall also include a
certification in the form attached hereto as Exhibit R-1 (the "Certification"),
which shall be signed by the senior officer of the Depositor in charge of
securitization.

                  The Trustee shall subject to the provisions of Sections 8.01
and 8.02 hereof, indemnify and hold harmless the Depositor and its officers,
directors and Affiliates from and against any losses, damages, penalties, fines,
forfeitures, reasonable and necessary legal fees and related costs, judgments
and other costs and expenses arising out of or based upon third party claims
relating to information included in any Form 10-K provided by the Trustee other
than any losses, damages, penalties, fines, forfeitures, reasonable and
necessary legal fees and related costs arising out of third party claims
relating to information contained in the Certification, the Master Servicer's
annual statement of compliance described under Section 3.20 and the accountant's
report described under Section 3.21 which are included in such Form 10-K.

                  (d)      In addition, the Trustee shall sign a certification
(in the form attached hereto as Exhibit R-2) for the benefit of the Depositor
and its officers, directors and Affiliates regarding certain aspects of items 1
through 3 of the Certification (provided, however, that the Trustee shall not
undertake an analysis of the accountant's report attached as an exhibit to the
Form 10-K). The Trustee's certification shall be delivered to the Depositor by
no later than March 18th of each year (or if such day is not a Business Day, the
immediately preceding Business Day) and the Depositor shall deliver the
Certification to the Trustee for filing no later than March 20th of each year
(or if such day is not a Business Day, the immediately preceding Business Day).

                  In addition, the Trustee shall indemnify and hold harmless the
Depositor and its officers, directors and Affiliates from and against any
losses, damages, penalties, fines, forfeitures, reasonable and necessary legal
fees and related costs, judgments and other costs and expenses arising out of or
based upon a breach of the Trustee's obligations under this Section 3.22(b) or
the Trustee's negligence, bad faith or willful misconduct in connection
therewith. If the indemnification provided for herein is unavailable or
insufficient to hold harmless the Depositor, then the Trustee, in connection
with a breach of the Trustee's obligations under this Section 3.22(b) or the
Trustee's negligence, bad faith or willful misconduct in connection


                                       94
<PAGE>


therewith, agrees that it shall contribute to the amount paid or payable by the
Depositor as a result of the losses, claims, damages or liabilities of the
Depositor in such proportion as is appropriate to reflect the relative fault of
the Depositor on the one hand and the Trustee on the other.

                  (e)      Upon any filing with the Securities and Exchange
Commission, the Trustee shall promptly deliver to the Depositor a copy of any
executed report, statement or information.

                  (f)      Prior to January 30 of the first year in which the
Trustee is able to do so under applicable law, the Trustee shall file a Form 15
Suspension Notification with respect to the Trust.

                  (g)      To the extent that, following the Closing Date, the
Depositor certifies that reports and certifications differing from those
required under this Section 3.22(b) comply with the reporting requirements under
the Exchange Act, the Trustee hereby agrees that it will reasonably cooperate to
amend the provisions of this Section 3.22(b) in order to comply with such
amended reporting requirements and such amendment of this Section 3.22(b). Any
such amendment may result in the reduction of the reports filed by the Depositor
under the Exchange Act. Notwithstanding the foregoing, the Trustee shall not be
obligated to enter into any amendment pursuant to this Section that adversely
affects its obligations and immunities under this Agreement.

                  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, in trust for the
benefit of the Certificateholders. The Master Servicer, on behalf of REMIC 1,
shall sell any REO Property as soon as practical and in any event no later than
the end of the third full taxable year after the taxable year in which such
REMIC 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 such three-year period, unless the Master Servicer shall have
delivered to the Trustee and the NIMS Insurer an Opinion of Counsel acceptable
to the NIMS Insurer and addressed to the Trustee, the NIMS Insurer and the
Depositor, to the effect that the holding by the REMIC of such REO Property
subsequent to three years after its acquisition will not result in the
imposition on the REMIC of taxes on "prohibited transactions" thereof, as
defined in Section 860F of the Code, or cause any of the REMICs created
hereunder to fail to qualify as a REMIC under Federal law at any time that any
Certificates are outstanding. The Master 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 of the REMICs
created hereunder 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 Master Servicer shall separately account for all
funds collected and received in connection with the operation of any REO
Property and shall establish and maintain,


                                       95
<PAGE>


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 Master Servicer
shall be permitted to allow the Collection Account to serve as the REO Account,
subject to separate ledgers for each REO Property. The Master Servicer shall be
entitled to retain or withdraw any interest income paid on funds deposited in
the REO Account.

                  (c)      The Master 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 Master Servicer manages and operates
similar property owned by the Master Servicer or any of its Affiliates, all on
such terms and for such period (subject to the requirement of prompt disposition
set forth in Section 3.23(a)) as the Master Servicer deems to be in the best
interests of Certificateholders. In connection therewith, the Master 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 Master Servicer's receipt thereof, and
shall thereafter deposit in the REO Account, in no event more than two Business
Days after the Master 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.

                  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 Master
Servicer shall advance from its own funds such amount as is necessary for such
purposes if, but only if, the Master Servicer would make such advances if the
Master Servicer owned the REO Property and if in the Master Servicer's judgment,
the payment of such amounts will be recoverable from the rental or sale of the
REO Property.

                  Notwithstanding the foregoing, neither the Master Servicer nor
the Trustee shall:

                  (A)      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;

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

                  (C)      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


                                       96
<PAGE>


         default on the related Mortgage Loan became imminent, all within the
         meaning of Section 856(e)(4)(B) of the Code; or

                  (D)      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 Master Servicer has obtained an Opinion of
Counsel, provided to the Trustee and the NIMS Insurer, 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 the REMIC, in which case the Master Servicer may take such actions
as are specified in such Opinion of Counsel.

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

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

                  (2)      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 Master
         Servicer as soon as practicable, but in no event later than thirty days
         following the receipt thereof by such Independent Contractor;

                  (3)      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 the Master 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

                  (4)      the Master 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 Master 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 Master Servicer
by such Independent Contractor, and nothing in this Agreement shall be deemed to
limit or modify such indemnification. The Master Servicer shall be solely liable
for all fees owed by it to any such Independent Contractor, irrespective of
whether the Master 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 Master Servicer, such amounts shall be reimbursable as Servicing
Advances made by the Master Servicer.

                  (d)      In addition to the withdrawals permitted under
Section 3.23(c), the Master 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


                                       97
<PAGE>


Advances and Advances made in respect of such REO Property or the related
Mortgage Loan. On the Master Servicer Remittance Date, the Master Servicer shall
withdraw from each REO Account maintained by it and deposit into the
Distribution 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 related Prepayment Period, 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 Master Servicer in a
manner, at such price and upon such terms and conditions as shall be in
conformity with the requirements of the Loss Mitigation Procedures and as shall
be normal and usual in its Servicing Standard.

                  (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 Master Servicer or
any Sub-Servicer as provided above, shall be deposited in the Distribution
Account in accordance with Section 3.10(d)(ii) on the Master 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 Master 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
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 Master Servicer in
                                    Respect of Prepayment Interest Shortfalls.

                  Not later than 1:00 p.m. New York time on each Master Servicer
Remittance Date, the Master 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 and (B) its
aggregate Servicing Fee for the related Due Period and any Prepayment Interest
Excess earned during the related Prepayment Period. The Master 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 Funds and distributed therewith on the next Distribution Date. The
Master Servicer shall not be obligated to pay Compensating Interest with respect
to Relief Act Interest Shortfalls.

                  SECTION 3.25.     [Reserved]

                  SECTION 3.26.     Obligations of the Master Servicer in
                                    Respect of Mortgage Rates and Monthly
                                    Payments.

                  In the event that a shortfall in any collection on or
liability with respect to the Mortgage Loans in the aggregate results from or is
attributable to adjustments to Mortgage


                                       98
<PAGE>


Rates, Monthly Payments or Stated Principal Balances that were made by the
Master Servicer in a manner not consistent with the terms of the related
Mortgage Note and this Agreement, the Master Servicer, upon discovery or receipt
of notice thereof, immediately shall deposit in the Collection 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 3.26
shall not limit the ability of the Master 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 3.27.     Solicitations.

                  From and after the Closing Date, the Master 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 Master 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 Master Servicer may solicit any Mortgagor for whom the Master 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
Master Servicer or any 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 Master Servicer
prohibited from responding to unsolicited requests or inquiries made by a
Mortgagor or an agent of a Mortgagor. Furthermore, the Master Servicer shall be
permitted to include in its monthly statements to borrowers or otherwise,
statements regarding the availability of the Master Servicer's counseling
services with respect to refinancing mortgage loans.

                  SECTION 3.28.     Net WAC Rate Carryover Reserve Account.

                  No later than the Closing Date, the Trustee shall establish
and maintain with itself a separate, segregated trust account titled, "Net WAC
Rate Carryover Reserve Account, Wells Fargo Bank, N.A., as Trustee, in trust for
registered Holders of Option One Mortgage Loan Trust 2005-1, Asset-Backed
Certificates, Series 2005-1." The amount deposited in the Net WAC Rate Carryover
Reserve Account will include any payments received by the Trustee under the Cap
Contracts and deposited into the Net WAC Rate Carryover Reserve Account.

                  On each Distribution Date as to which there is a Net WAC Rate
Carryover Amount payable to the Class A Certificates and/or the Mezzanine
Certificates, the Trustee has been directed by the Class C Certificateholders
to, and therefore will, deposit into the Net WAC Rate Carryover Reserve Account
the amounts described in Section 4.01(d)(iv), rather than distributing such
amounts to the Class C 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


                                       99
<PAGE>


Certificates and/or the Mezzanine Certificates in the amounts and priorities set
forth in Section 4.01(d).

                  On each Distribution Date, any amounts remaining in the Net
WAC Rate Carryover Reserve Account (representing payments received by the
Trustee under the Cap Contracts) after the payment of any Net WAC Rate Carryover
Amounts on the Class A Certificates and the Mezzanine Certificates for such
Distribution Date, shall be payable to the Trustee.

                  For federal and state income tax purposes, the Class C
Certificateholders will be deemed to be the owners of the Net WAC Rate Carryover
Reserve Account and all amounts deposited into the Net WAC Rate Carryover
Reserve Account (other than amounts received under the Cap Contracts) shall be
treated as amounts distributed by REMIC 3 to the Holder of the Class C Interest
and by REMIC 4 to the Holders of the Class C Certificates. Upon the termination
of the Trust, 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 and distributed to the
Class C Certificateholders or their designees. The Net WAC Rate Carryover
Reserve Account will be part of the Trust 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).

                  By accepting a Class C Certificate, each Class C
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 C
Certificateholders. By accepting a Class C Certificate, each Class C
Certificateholder further agrees that such direction is given for good and
valuable consideration, the receipt and sufficiency of which is acknowledged by
such acceptance.

                  At the direction of the Holders of a majority in Percentage
Interest in the Class C Certificates, the Trustee shall direct any depository
institution maintaining the Net WAC Rate Carryover Reserve Account to invest the
funds in such 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 or an Affiliate manages or advises such investment, 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 or an Affiliate manages or
advises such investment. If no investment direction of the Holders of a majority
in Percentage Interest in the Class C Certificates with respect to the Net WAC
Rate Carryover Reserve Account is received by the Trustee, the Trustee shall
invest the funds in such account in Permitted Investments managed by the Trustee
or an Affiliate of the kind described in clause (vi) of the definition of
Permitted Investments.

                  For federal tax return and information reporting, the value of
the right of the Holders of the Group I Certificates, Group II 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 shall be
$84,000, $260,000 and $304,000, respectively.

                  SECTION 3.29.     Advancing Facility.

                  (a)      The Master Servicer and/or the Trustee on behalf of
the Trust Fund, in either case, with the consent of the NIMS Insurer and the
Master Servicer in the case of the Trustee, is hereby authorized to enter into a
facility (the "Advancing 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 Master Servicer's obligation to fund such Advances and/or
Servicing Advances. If the Master Servicer enters into such an Advancing
Facility pursuant to this Section 3.29, 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 Advancing Facility. To the extent
that an Advancing Person funds any Advance or any Servicing Advance and provides
the Trustee with notice acknowledged by the Servicer 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 3.29(b). Such notice from the Advancing Person 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 Advancing Facility that entitle the Advancing Person to request
reimbursement from the Trustee, rather than the Master Servicer, and include the
Master Servicer's acknowledgment thereto or proof of an Event of Default under
the Advancing Facility. The Trustee shall have no duty or liability with respect
to any calculation of any reimbursement to be paid to an Advancing Person and
shall be entitled to rely without independent investigation on the Advancing
Person's notice provided pursuant to this Section 3.29. 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 a Master
Servicer or a Sub-Servicer pursuant to Section 6.06 hereof and will not be
deemed to be a Sub-Servicer under this Agreement. If the terms of a facility
proposed to be entered into with an Advancing Person by the Trust Fund would not
materially and adversely affect the interests of any Certificateholder, then the
NIMS Insurer shall not withhold its consent to the Trust Fund's entering such
facility.

                  (b)      If an Advancing Facility is entered into, then the
Master Servicer shall not be permitted to reimburse itself therefor under
Section 3.11(a)(ii), Section 3.11(a)(iii), Section 3.11(a)(vi), Section
3.11(a)(vii) Section 3.11(a)(viii) and Section 4.04(b) prior to the remittance
to the Trust Fund, but instead the Master Servicer shall include such amounts in
the applicable remittance to the Trustee made pursuant to Section 3.10(a). The
Trustee is hereby authorized to pay to the Advancing Person, reimbursements for
Advances and Servicing Advances from the Distribution Account to the same extent
the Master 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), Section 3.11(a)(vi), Section 3.11(a)(vii), Section
3.11(a)(viii) or Section 4.04(b), as the case may be, had the Master 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.

                  (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 3.29 or to any other
provision of this Agreement that may be necessary or appropriate to effect the
terms of an Advancing Facility as


                                      101
<PAGE>


described generally in this Section 3.29, including amendments to add provisions
relating to a successor master servicer, may be entered into by the Trustee and
the Master Servicer without the consent of any Certificateholder but with the
consent of the NIMS Insurer, notwithstanding anything to the contrary in this
Agreement.

                  SECTION 3.30.     PMI Policy; Claims Under the PMI Policy

                  Notwithstanding anything to the contrary elsewhere in this
Article III, the Master Servicer shall not agree to any modification or
assumption of a PMI Mortgage Loan or take any other action with respect to a PMI
Mortgage Loan that could result in denial of coverage under the PMI Policy. The
Master Servicer shall notify the PMI Insurer that the Trustee, on behalf of the
Trust, is the Insured, as that term is defined in the PMI Policy, of each PMI
Mortgage Loan. The Master Servicer shall, on behalf of the Trust, prepare and
file on a timely basis with the PMI Insurer, all claims which may be made under
the PMI Policy with respect to the PMI Mortgage Loans. Consistent with all
rights and obligations hereunder, the Master Servicer shall take all actions
required of the Insured under the PMI Policy (except for the calculation and the
payment of the PMI Premium with respect to funds available in the Distribution
Account). Any amount received from the PMI Insurer with respect to any such PMI
Mortgage Loan shall be deposited by the Master Servicer, no later than two
Business Days following receipt thereof, into the Collection Account.

                  The Trustee is hereby directed to execute and deliver the PMI
Letter Agreement, on behalf of the Trust, among the Trustee, the PMI Insurer and
the Master Servicer for the benefit of the Trust Fund.

         such Distribution Date; and

                  (ii)     concurrently, to the Holders of each Class of Group I

         Class, an amount equal to the excess, if any, of (x) the amount
         required to be distributed pursuant to Section 4.01(a)(I)(i) above for
         such Distribution Date over (y) the amount actually distributed
         pursuant to such section from the Group I Interest Remittance Amount.

                  (III)    On each Distribution Date, following the
distributions made pursuant to Section 4.01(a)(I) and (II) above, the sum of the
Group I Interest Remittance Amount and the Group II Interest Remittance Amount

                  (vi)     if such Distribution Date follows the Prepayment

                  (e)      METHOD OF DISTRIBUTION. The Trustee shall make
distributions in respect of a Distribution Date to each Certificateholder of
record on the related Record Date (other than as provided in Section 10.01
respecting the final distribution), in the case of Certificateholders of the
Regular Certificates, by check or money order mailed to such Certificateholder
at the address appearing in the Certificate Register, or by wire transfer.
Distributions among Certificateholders shall be made in proportion to the
Percentage Interests evidenced by the Certificates held by such
Certificateholders.

                  (f)      DISTRIBUTIONS ON BOOK-ENTRY CERTIFICATES. Each
distribution with respect to a Book-Entry Certificate shall be paid to the
Depository, which shall credit 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. All such credits and disbursements
with respect to a Book-Entry Certificate are to be made by the Depository and
the Depository Participants in accordance with the provisions of the
Certificates. None of the Trustee, the Depositor, the Master Servicer or the
Originator shall have any responsibility therefor except as otherwise provided
by applicable law.

                  (g)      SUBSEQUENT RECOVERIES. On each Distribution Date,
following all distributions on the Certificates pursuant to Section 4.01, an
amount equal to the amount of Subsequent Recoveries deposited into the
Collection Account pursuant to Section 3.10 and included in the Available Funds
for such Distribution Date will be applied to increase the Certificate Principal
Balance of the Class of Certificates with the Highest Priority up to the extent
of such Realized Losses previously allocated to that Class of Certificates
pursuant to Section 4.08. An amount equal to the amount of any remaining
Subsequent Recoveries will 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 4.08, and so on. Holders of such Certificates
will not be entitled to any distribution in respect of interest on the amount of
such increases for any 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.

                  (h)      It is the intention of all of the parties hereto that
the Class C Certificates receive all principal and interest received by the
Trust on the Mortgage Loans that is not otherwise distributable to any other
Class of Regular Certificates or REMIC Regular Interests. If the Trustee
determines that the Residual Certificates are entitled to any distributions, the
Trustee, prior to any such distribution to any Residual Certificate, shall
notify the Depositor of such impending distribution. Upon such notification, the
Depositor will request an amendment to the Pooling and Servicing Agreement to
revise such mistake in the distribution provisions. The Residual Certificate
Holders, by acceptance of their Certificates, and the Servicer(s) hereby agree
and no further consent shall be necessary, notwithstanding anything to the
contrary in Section 11.01 of the Pooling and Servicing Agreement.

above, aggregated for such calendar year or applicable portion thereof during
which such Person was a Certificateholder. Such obligation of the Trustee shall
be deemed to have been satisfied to the extent that substantially comparable

                  (c)      On each Distribution Date, the Trustee shall forward

                  SECTION 4.04.     Remittance Reports; Advances.

                  (a)      On the second Business Day following each
Determination Date but in no event later than the earlier of (i) such date which
would allow the indenture trustee to submit a claim to the NIMS Insurer under
the Indenture so as to allow a timely payment by the NIMS Insurer under the
insurance policy related to the notes insured by the NIMS Insurer and (ii) the
20th day of each month (or if such 20th day is not a Business Day, the preceding
Business Day), the Master Servicer shall deliver to the Trustee and the NIMS
Insurer by telecopy or electronic mail (or by such other means as the Master
Servicer and the Trustee may agree from time to time) a Remittance Report with
respect to the related Distribution Date. Not later than the 20th day of each
month (or if such 20th day is not a Business Day, the preceding Business Day),
the Master Servicer shall deliver or cause to be delivered to the Trustee in
addition to the information provided on the Remittance Report, such other
information reasonably available to it


                                      112
<PAGE>


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 4.03. The Trustee shall not be responsible to recompute, recalculate or
verify any information provided to it by the Master Servicer.

                  (b)      The amount of Advances to be made by the Master
Servicer for any Distribution Date shall equal, subject to Section 4.04(d), the
sum of (i) the aggregate amount of Monthly Payments (net of the related
Servicing Fee), due during the related Due Period in respect of the Mortgage
Loans, which Monthly Payments were delinquent on a contractual basis as of the
Close of Business on the related Determination Date and (ii) with respect to
each REO Property, which REO Property was acquired during or prior to the
related Due Period and as to which REO Property an REO Disposition did not occur
during the related Due 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
Distribution Account pursuant to Section 3.23 for distribution on such
Distribution Date.

                  (c)      On or before 1:00 p.m. New York time on the Master
Servicer Remittance Date, the Master Servicer shall remit in immediately
available funds to the Trustee for deposit in the Distribution 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 Collection 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 Collection Account that amounts held for
future distribution have been, as permitted by this Section 4.04, used by the
Master 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 Master Servicer with respect to the Mortgage Loans and REO Properties.
Any amounts held for future distribution used by the Master Servicer to make an
Advance as permitted in the preceding sentence or withdrawn by the Master
Servicer as permitted in Section 3.11(a)(ii) in reimbursement of Advances
previously made shall be appropriately reflected in the Master Servicer's
records and replaced by the Master Servicer by deposit in the Collection Account
on or before any future Master Servicer Remittance Date to the extent that the
Available Funds for the related Distribution Date (determined without regard to
Advances to be made on the Master 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 or reimburse for
previously made Advances. The Trustee will provide notice to the NIMS Insurer
and the Master Servicer by telecopy by the Close of Business on any Master
Servicer Remittance Date in the event that the amount remitted by the Master
Servicer to the Trustee on such date is less than the Advances required to be
made by the Master Servicer for the related Distribution Date, as set forth in
the related Remittance Report.

                  (d)      The obligation of the Master 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, shall continue
until the Mortgage Loan is paid in full or until the recovery of all Liquidation
Proceeds thereon.

<PAGE>


                  (e)      Notwithstanding anything herein to the contrary, no
Advance or Servicing Advance shall be required to be made hereunder by the
Master Servicer if such Advance or Servicing Advance would, if made, constitute
a Nonrecoverable Advance. The determination by the Master Servicer that it has
made a Nonrecoverable Advance or that any proposed Advance or Servicing Advance,
if made, would constitute a Nonrecoverable Advance, shall be evidenced by an
Officers' Certificate of the Master Servicer delivered to the NIMS Insurer, the
Depositor and the Trustee.

                  SECTION 4.05.     Pre-Funding Accounts.

Account") and "Group II Pre-Funding Account, Wells Fargo Bank, N.A., as trustee
for the registered holders of Option One Mortgage Loan Trust 2005-1,
Asset-Backed Certificates, Series 2005-1" (the "Group II Pre-Funding Account").
The Trustee shall, promptly upon receipt, deposit in the applicable Pre-Funding

                  (b)      The Trustee will invest funds deposited in the
Pre-Funding Accounts as directed by the Master Servicer in Permitted Investments
with a maturity date (i) no later than the Business Day immediately preceding

pursuant to this Agreement, if a Person other than the Trustee or an Affiliate
manages or advises such investment, (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 or an Affiliate manages or advises such investment or (iii)

Pre-Funding Account and the Group II Pre-Funding Account shall be transferred to
the Depositor or its designee, as applicable, at the following times: (i) on the
Business Day immediately preceding each Distribution Date, if a Person other
than the Trustee or an Affiliate of the Trustee manages or advises such
investment, or on each Distribution Date, if the Trustee or an Affiliate of the
Trustee manages or advises such investment, (ii) on the Business Day immediately
preceding each Subsequent Transfer Date, if a Person other than the Trustee or
an Affiliate of the Trustee manages or advises such investment, or on each
Subsequent Transfer Date, if the Trustee or an Affiliate of the Trustee manages
or advises such investment or (iii) within one Business Day of the Trustee's
receipt thereof. The Master Servicer shall deposit in the Pre-Funding Accounts
the amount of any net loss incurred in respect of any such Permitted Investment
immediately upon realization of such loss without any right of reimbursement
therefor. At no time will the Pre-Funding Accounts be assets of any REMIC
created hereunder.

                  (c)      Amounts on deposit in the Pre-Funding Accounts shall
be withdrawn by the Trustee as follows:

                  (i)      On any Subsequent Transfer Date, the Trustee shall
         withdraw from the Group I Pre-Funding Account or the Group II
         Pre-Funding Account, as applicable, an amount equal to 100% of the
         Stated Principal Balances of the Subsequent Group I Mortgage Loans or
         the Subsequent Group II Mortgage Loans, as applicable, transferred and
         assigned to the Trustee for deposit in the Mortgage Pool on such
         Subsequent Transfer Date and pay such amount to or upon the order of
         the Depositor upon satisfaction of the conditions set forth in Section
         2.08 with respect to such transfer and assignment;

                  (ii)     If the amount on deposit in the Pre-Funding Accounts
         (exclusive of investment income) has not been reduced to zero during
         the Funding Period, on the day immediately following the termination of
         the Funding Period, the Trustee shall deposit into the Distribution
         Account any amounts remaining in the Pre-Funding Accounts (exclusive of
         investment income) for distribution in accordance with the terms
         hereof;

                  (iii)    To withdraw any amount not required to be deposited
         in the Pre-Funding Accounts or deposited therein in error; and

                  (iv)     To clear and terminate the Pre-Funding Accounts upon
         the earlier to occur of (A) the Distribution Date immediately following
         the end of the Funding Period and (B) the termination of this
         Agreement, with any amounts remaining on deposit therein being paid to
         the Holders of the Certificates then entitled to distributions in
         respect of principal.

                  Withdrawals pursuant to clauses (i), (ii) and (iii) shall be
treated as contributions of cash to REMIC 1 on the date of withdrawal.

         payments that are attributable to an Overcollateralization Reduction
         Amount shall be allocated to Holders of (i) REMIC 2 Regular Interest
         LT2AA and REMIC 2 Regular Interest LT2P, in that order and (ii) REMIC 2

         Loans in the related Loan Group; second, to each REMIC 2 Regular
         Interest ending with the designation "SUB," so that the Uncertificated
         Balance of each such REMIC 2 Regular Interest is equal to 0.01% of the

         Loans in the related Loan Group over (y) the current Certificate
         Principal Balance of the Class A Certificate in the related Loan Group
         (except that if any such excess is a larger number than in the
         preceding distribution period, the least amount of principal shall be
         distributed to such REMIC 2 Regular Interests such that the REMIC 2
         Subordinated Balance Ratio is maintained); and third, any remaining
         principal to REMIC 2 Regular Interest LT2XX; and

                  (v)      Notwithstanding the distributions described in this
         Section 4.07, distribution of funds shall be made only in accordance

Period will be distributed by REMIC 2 to the Holders of REMIC 2 Regular Interest
LT2P. The payment of the foregoing amounts to the Holders of REMIC 2 Regular
Interest LT2P shall not reduce the Uncertificated Principal Balance thereof.

Distribution Date as follows: first, as provided in Section 1.03, to the
interest accrued on the Class C Certificates after the allocation thereto of
certain interest shortfalls as provided in Section 1.03; second, to the Class C
Certificates (determined for purposes of this section 4.08 as the amount by
which (A) the aggregate Uncertificated Balance of the REMIC I Regular Interests
immediately preceding such Distribution Date exceed (B) the aggregate
Certificate Principal Balances of the Class A Certificates, the Mezzanine
Certificates and the Class P Certificates immediately preceding such
Distribution Date), until the Certificate Principal Balance thereof has been
reduced to zero; third, to the Class M-9 Certificates, until the Certificate
Principal Balance thereof has been reduced to zero; fourth, to the Class M-8
Certificates, until the Certificate Principal Balance thereof has been reduced
to zero; fifth, to the Class M-7 Certificates, until the Certificate Principal

Certificate Principal Balance thereof has 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 Mezzanine Certificate
or a Class A-1B Certificate on any Distribution Date shall be made by reducing

the amount otherwise payable in respect thereof pursuant to Section 4.01(d)(xx).
No allocations of any Realized Losses shall be made to the Certificate Principal
Balances of the Class A Certificates or the Class P Certificates.

                  (b)      All Realized Losses on the Group I Mortgage Loans

Realized Losses on the Initial Group I Mortgage Loans shall be allocated to
REMIC 1 Regular Interest LT1 until the Uncertificated Principal Balance of each
such REMIC 1 Regular Interest has been reduced to zero, and all Realized Losses
on the Subsequent Group I Mortgage Loans shall be allocated to REMIC 1 Regular
Interest LT1PF until the Uncertificated Principal Balance thereof has been
reduced to zero. All Realized Losses on the Group II Mortgage Loans shall be

                  SECTION 5.01.     The Certificates.

                  Each of the Class A Certificates, the Mezzanine Certificates,
the Class P Certificates, the Class C Certificates and the Residual Certificates
shall be substantially in the forms annexed hereto as exhibits, and shall, on
original issue, be executed, authenticated and delivered by the Trustee to or
upon the order of the Depositor concurrently with the sale and assignment to the
Trustee of the Trust Fund. The Class A Certificates and the Mezzanine
Certificates shall be initially evidenced by one or more Certificates
representing a Percentage Interest with a minimum dollar denomination of $25,000
and integral dollar multiples of $1.00 in excess thereof, except that one
Certificate of each such Class of Certificates may be in a different
denomination so that the sum of the denominations of all outstanding
Certificates of such Class shall equal the Certificate Principal Balance or
Notional Amount of such Class on the Closing Date. The Class P Certificates, the
Class C Certificates and the Residual Certificates are issuable in any
Percentage Interests; PROVIDED, HOWEVER, that the sum of all such percentages
for each such Class totals 100% and no more than ten Certificates of each Class
may be issued and outstanding at any one time.

                  The Certificates shall be executed on behalf of the Trust by
manual or facsimile signature on behalf of the Trustee by a Responsible Officer.
Certificates bearing the manual or facsimile signatures of individuals who were,
at the time when such signatures were affixed, authorized to sign on behalf of
the Trustee shall bind the Trust, notwithstanding that such individuals or any
of them have ceased to be so authorized prior to the authentication and delivery
of such Certificates or did not hold such offices at the date of such
Certificate. No Certificate shall be entitled to any benefit under this
Agreement or be valid for any purpose, unless such Certificate shall have been
manually authenticated by the Trustee substantially in the form provided for
herein, and such authentication upon any Certificate shall be conclusive
evidence, and the only evidence, that such Certificate has been duly
authenticated and delivered hereunder. All Certificates shall be dated the date
of their authentication. Subject to Section 5.02(c), the Class A Certificates
and the Mezzanine Certificates shall be Book-Entry Certificates. The other
Classes of Certificates shall not be Book-Entry Certificates.

                  SECTION 5.02.     Registration of Transfer and Exchange of
                                    Certificates.

                  (a)      The Certificate Registrar shall cause to be kept at
the Corporate Trust Office a Certificate Register in which, subject to such
reasonable regulations as it may prescribe, the Certificate Registrar shall
provide for the registration of Certificates and of transfers and exchanges of
Certificates as herein provided. The Trustee shall initially serve as
Certificate Registrar for the purpose of registering Certificates and transfers
and exchanges of Certificates as herein provided.

                  Upon surrender for registration of transfer of any Certificate
at any office or agency of the Certificate Registrar maintained for such purpose
pursuant to the foregoing paragraph and, in the case of a Residual Certificate,
upon satisfaction of the conditions set forth below, the Trustee on behalf of
the Trust shall execute, authenticate and deliver, in the name of


                                      122
<PAGE>


the designated transferee or transferees, one or more new Certificates of the
same aggregate Percentage Interest.

                  At the option of the Certificateholders, Certificates may be
exchanged for other Certificates in authorized denominations and the same
aggregate Percentage Interests, upon surrender of the Certificates to be
exchanged at any such office or agency. Whenever any Certificates are so
surrendered for exchange, the Trustee shall execute on behalf of the Trust and
authenticate and deliver the Certificates which the Certificateholder making the
exchange is entitled to receive. Every Certificate presented or surrendered for
registration of transfer or exchange shall (if so required by the Trustee or the
Certificate Registrar) be duly endorsed by, or be accompanied by a written
instrument of transfer satisfactory to the Trustee and the Certificate Registrar
duly executed by, the Holder thereof or his attorney duly authorized in writing.
In addition, (i) with respect to each Class R Certificate, the holder thereof
may exchange, in the manner described above, such Class R Certificate for three
separate certificates, each representing such holder's respective Percentage
Interest in the Class R-1 Interest, the Class R-2 Interest and the Class R-3
Interest, respectively, in each case that was evidenced by the Class R
Certificate being exchanged and (ii) with respect to each Class R-X Certificate,
the holder thereof may exchange, in the manner described above, such Class R-X
Certificate for two separate certificates, each representing such holder's
respective Percentage Interest in the Class R-4 Interest and the Class R-5
Interest, respectively, in each case that was evidenced by the Class R-X
Certificate being exchanged.

                  (b)      Except as provided in paragraph (c) below, the
Book-Entry Certificates shall at all times remain registered in the name of the
Depository or its nominee and at all times: (i) registration of such
Certificates may not be transferred by the Trustee except to another Depository;
(ii) the Depository shall maintain book-entry records with respect to the
Certificate Owners and with respect to ownership and transfers of such
Certificates; (iii) ownership and transfers of registration of such Certificates
on the books of the Depository shall be governed by applicable rules established
by the Depository; (iv) the Depository may collect its usual and customary fees,
charges and expenses from its Depository Participants; (v) the Trustee shall for
all purposes deal with the Depository as representative of the Certificate
Owners of the Certificates for purposes of exercising the rights of Holders
under this Agreement, and requests and directions for and votes of such
representative shall not be deemed to be inconsistent if they are made with
respect to different Certificate Owners; (vi) the Trustee may rely and shall be
fully protected in relying upon information furnished by the Depository with
respect to its Depository Participants and furnished by the Depository
Participants with respect to indirect participating firms and Persons shown on
the books of such indirect participating firms as direct or indirect Certificate
Owners; and (vii) the direct participants of the Depository shall have no rights
under this Agreement under or with respect to any of the Certificates held on
their behalf by the Depository, and the Depository may be treated by the Trustee
and its agents, employees, officers and directors as the absolute owner of the
Certificates for all purposes whatsoever.

                  All transfers by Certificate Owners of Book-Entry Certificates
shall be made in accordance with the procedures established by the Depository
Participant or brokerage firm representing such Certificate Owners. Each
Depository Participant shall only transfer Book-Entry Certificates of
Certificate Owners that it represents or of brokerage firms for which it acts as
agent in accordance with the Depository's normal procedures. The parties hereto
are hereby authorized to execute a Letter of Representations with the Depository
or take such other action as


                                      123
<PAGE>


may be necessary or desirable to register a Book-Entry Certificate to the
Depository. In the event of any conflict between the terms of any such Letter of
Representation and this Agreement, the terms of this Agreement shall control.

                  (c)      If (i)(x) the Depository or the Depositor advises the
Trustee in writing that the Depository is no longer willing or able to discharge
properly its responsibilities as Depository and (y) the Trustee or the Depositor
is unable to locate a qualified successor or (ii) after the occurrence of a
Master Servicer Event of Termination, the Certificate Owners of the Book-Entry
Certificates representing Percentage Interests of such Classes aggregating not
less than 51% advise the Trustee and Depository through the Financial
Intermediaries and the Depository Participants in writing that the continuation
of a book-entry system through the Depository to the exclusion of definitive,
fully registered certificates (the "Definitive Certificates") to Certificate
Owners is no longer in the best interests of the Certificate Owners. Upon
surrender to the Certificate Registrar of the Book-Entry Certificates by the
Depository, accompanied by registration instructions from the Depository for
registration, the Trustee shall, at the Depositor's expense, in the case of (ii)
above, or the Master Servicer's expense, in the case of (i) and (iii) above,
execute on behalf of the Trust and authenticate the Definitive Certificates.
Neither the Depositor nor the Trustee shall be liable for any delay in delivery
of such instructions and may conclusively rely on, and shall be protected in
relying on, such instructions. Upon the issuance of Definitive Certificates, the
Trustee, the Certificate Registrar, the Master Servicer, any Paying Agent and
the Depositor shall recognize the Holders of the Definitive Certificates as
Certificateholders hereunder.

                  (d)      No transfer, sale, pledge or other disposition of any
Class C Certificate, Class P Certificate or Residual Certificate shall be made
unless such disposition is exempt from the registration requirements of the
Securities Act of 1933, as amended (the "1933 Act"), and any applicable state
securities laws or is made in accordance with the 1933 Act and laws. In the
event of any such transfer (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 and the Certificate Registrar shall
each require receipt of: (I)(i) if such transfer is purportedly being made in
reliance upon Rule 144A (as evidenced by the investment letter delivered to the
Trustee, in substantially the form attached hereto as Exhibit J) under the 1933
Act 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 Depositor, the Trustee, the Master Servicer, in
its capacity as such, or the Trust Fund), 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; or (II) the Trustee shall require the transferor to
execute a transferor certificate (in substantially the form attached hereto as
Exhibit L) and the transferee to execute an investment letter (in substantially
the form attached hereto as Exhibit J) acceptable to and in form and substance
reasonably satisfactory to the Depositor and the Trustee certifying to the
Depositor and the Trustee the facts surrounding such transfer, which investment
letter shall not be an expense of the Trustee or the Depositor. The Holder of a
Class C Certificate, Class P Certificate or Residual Certificate desiring to
effect such transfer shall, and does hereby agree to, indemnify


                                      124
<PAGE>


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.

                  No transfer of a Class C Certificate, Class P Certificate or
Residual Certificate or any interest therein shall be made to any Plan subject
to ERISA or Section 4975 of the Code, any Person acting, directly or indirectly,
on behalf of any such Plan or any Person acquiring such 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 M, unless the Trustee is provided with an
Opinion of Counsel for the benefit of the Depositor, the Trustee and the Master
Servicer and upon which they may rely, which establishes to the satisfaction of
the Trustee that the purchase of such Certificates is permissible under
applicable law, will not constitute or result in any non-exempt prohibited
transaction under ERISA or Section 4975 of the Code and will not subject the
Depositor, the Master 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 Master Servicer, the
Trustee or the Trust Fund. Neither an Opinion of Counsel nor any certification
shall be required 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 Certificate to the issuer under the Indenture or the indenture
trustee under the Indenture or (iii) 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.

                  Each Transferee of a Mezzanine Certificate will be deemed to
have represented by virtue of its purchase or holding of such Certificate (or
interest therein) that either (a) such Transferee is not a Plan or purchasing
such Certificate with Plan Assets, (b) it has acquired and is holding such
Certificate in reliance on Prohibited Transaction Exemption ("PTE") 90-59, 55
Fed. Reg. 36724, as amended by PTE 2002-41, 67 Fed. Reg. 54487 (August 22, 2002)
(the "Exemption"), and that it understands that there are certain conditions to
the availability of the Exemption including that such Certificate must be rated,
at the time of purchase, not lower than "BBB-" (or its equivalent) by a Rating
Agency or (c) the following conditions are satisfied: (i) such Transferee is an
insurance company, (ii) the source of funds used to purchase or hold such
Certificate (or interest therein) is an "insurance company general account" (as
defined in U.S. Department of Labor Prohibited Transaction Class Exemption
("PTCE") 95-60, and (iii) the conditions set forth in Sections I and III of PTCE
95-60 have been satisfied.

                  If any Mezzanine Certificate, Class C Certificate, Class P
Certificate or Residual Certificate or any interest therein is acquired or held
in violation of the provisions of the two preceding paragraphs, 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 interest therein was effected in violation of the provisions of
the preceding two paragraphs shall indemnify and hold harmless the Depositor,
the Master Servicer, the NIMS Insurer, the Trustee


                                      125
<PAGE>


and the Trust from and against any and all liabilities, claims, costs or
expenses incurred by those parties as a result of that acquisition or holding.

                  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 agreed to be bound by the following provisions and to
have irrevocably appointed the Depositor or its designee as its attorney-in-fact
to negotiate the terms of any mandatory sale under clause (v) below and to
execute all instruments of transfer and to do all other things necessary in
connection with any such sale, and the rights of each Person acquiring any
Ownership Interest in a Residual Certificate are expressly subject to the
following provisions:

                  (i)      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.

                  (ii)     No Person shall acquire an Ownership Interest in a
         Residual Certificate unless such Ownership Interest is a pro rata
         undivided interest.

                  (iii)    In connection with any proposed transfer of any
         Ownership Interest in a Residual Certificate, the Trustee shall as a
         condition to registration of the transfer, require delivery to it, in
         form and substance satisfactory to it, of each of the following:

                           (A)      an affidavit in the form of Exhibit K hereto
                  from the proposed transferee to the effect that such
                  transferee is a Permitted Transferee and 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 who is not a Permitted
                  Transferee; and

                           (B)      a covenant of the proposed transferee to the
                  effect that the proposed transferee agrees to be bound by and
                  to abide by the transfer restrictions applicable to the
                  Residual Certificates.

                  (iv)     Any attempted or purported transfer of any Ownership
         Interest in a Residual Certificate in violation of the provisions of
         this Section shall be absolutely null and void and shall vest no rights
         in the purported transferee. If any purported transferee shall, in
         violation of the provisions of this Section, become a Holder of a
         Residual Certificate, then the prior Holder of such Residual
         Certificate that is a Permitted Transferee shall, upon discovery that
         the registration of transfer of such Residual Certificate was not in
         fact permitted by this Section, be restored to all rights as Holder
         thereof retroactive to the date of registration of 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 or for making any
         distributions due on such Residual Certificate to the Holder thereof or
         taking any other action with respect to such Holder under the
         provisions of this Agreement so long as the Trustee received the
         documents specified in clause (iii). The Trustee shall be entitled to
         recover from any Holder of a Residual Certificate that was in fact not
         a Permitted Transferee at the time such distributions were made all
         distributions made on such Residual Certificate. Any such distributions
         so recovered by the Trustee shall be


                                      126
<PAGE>


         distributed and delivered by the Trustee to the prior Holder of such
         Residual Certificate that is a Permitted Transferee.

                  (v)      If any Person other than a Permitted Transferee
         acquires any Ownership Interest in a Residual Certificate in violation
         of the restrictions in this Section, then the Trustee shall have the
         right but not the obligation, without notice to the Holder of such
         Residual Certificate or any other Person having an Ownership Interest
         therein, to notify the Depositor to arrange for the sale of such
         Residual Certificate. The proceeds of such sale, net of commissions
         (which may include commissions payable to the Depositor or its
         affiliates in connection with such sale), expenses and taxes due, if
         any, will be remitted by the Trustee to the previous Holder of such
         Residual Certificate that is a Permitted Transferee, except that in the
         event that the Trustee determines that the Holder of such Residual
         Certificate may be liable for any amount due under this Section or any
         other provisions of this Agreement, the Trustee may withhold a
         corresponding amount from such remittance as security for such claim.
         The terms and conditions of any sale under this clause (v) shall be
         determined in the sole discretion of the Trustee and it shall not be
         liable to any Person having an Ownership Interest in a Residual
         Certificate as a result of its exercise of such discretion.

                  (vi)     If any Person other than a Permitted Transferee
         acquires any Ownership Interest in a Residual Certificate in violation
         of the restrictions in this Section, then the Trustee upon receipt of
         reasonable compensation will provide to the Internal Revenue Service,
         and to the persons specified in Sections 860E(e)(3) and (6) of the
         Code, information needed to compute the tax imposed under Section
         860E(e)(5) of the Code on transfers of residual interests to
         disqualified organizations.

                  The foregoing provisions of this Section shall cease to apply
to transfers occurring on or after the date on which there shall have been
delivered to the Trustee and the NIMS Insurer, in form and substance
satisfactory to the Trustee and the NIMS Insurer, (i) written notification from
each Rating Agency that the removal of the restrictions on transfer set forth in
this Section will not cause such Rating Agency to downgrade its rating of the
Certificates and (ii) an Opinion of Counsel to the effect that such removal will
not cause any REMIC created hereunder to fail to qualify as a REMIC.

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

                  All Certificates surrendered for registration of transfer or
exchange shall be canceled by the Certificate Registrar and disposed of pursuant
to its standard procedures.

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

                  If (i) any mutilated Certificate is surrendered to the
Certificate Registrar or the Certificate Registrar receives evidence to its
satisfaction of the destruction, loss or theft of any Certificate and (ii) there
is delivered to the Trustee, the Depositor, the NIMS Insurer and the Certificate
Registrar such security or indemnity as may be required by them to save each of
them


                                      127
<PAGE>


harmless, then, in the absence of notice to the Trustee or the Certificate
Registrar that such Certificate has been acquired by a bona fide purchaser, the
Trustee shall execute on behalf of the Trust, authenticate and deliver, in
exchange for or in lieu of any such mutilated, destroyed, lost or stolen
Certificate, a new Certificate of like tenor and Percentage Interest. Upon the
issuance of any new Certificate under this Section, the Trustee or the
Certificate Registrar may require the payment of a sum sufficient to cover any
tax or other governmental charge that may be imposed in relation thereto and any
other expenses (including the fees and expenses of the Trustee and the
Certificate Registrar) in connection therewith. Any duplicate Certificate issued
pursuant to this Section, shall constitute complete and indefeasible evidence of
ownership in the Trust, 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.

                  The Master Servicer, the Depositor, the Trustee, the NIMS
Insurer, the Certificate Registrar, any Paying Agent and any agent of the Master
Servicer, the Depositor, the Trustee, the NIMS Insurer, the Certificate
Registrar, any Paying Agent or the Trustee may treat the Person, including a
Depository, 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 Master Servicer, the
Trust, the Trustee nor any agent of any of them shall be affected by notice to
the contrary.

                  SECTION 5.05.     Appointment of Paying Agent.

                  (a)      The Paying Agent shall make distributions to
Certificateholders from the Distribution Account pursuant to Section 4.01 and
shall report the amounts of such distributions to the Trustee. The duties of the
Paying Agent may include the obligation (i) to withdraw funds from the
Collection Account pursuant to Section 3.11(a) and for the purpose of making the
distributions referred to above and (ii) to distribute statements and provide
information to Certificateholders as required hereunder. The Paying Agent
hereunder shall at all times be an entity duly incorporated and validly existing
under the laws of the United States of America or any state thereof, authorized
under such laws to exercise corporate trust powers and subject to supervision or
examination by federal or state authorities. The Paying Agent shall initially be
the Trustee. The Trustee may appoint a successor to act as Paying Agent, which
appointment shall be reasonably satisfactory to the Depositor and the NIMS
Insurer.

                  (b)      The Trustee shall cause the Paying Agent (if other
than the Trustee) to execute and deliver to the Trustee an instrument in which
such Paying Agent shall agree with the Trustee that such Paying Agent shall hold
all sums, if any, held by it for payment to the Certificateholders in trust for
the benefit of the Certificateholders entitled thereto until such sums shall be
paid to such Certificateholders and shall agree that it shall comply with all
requirements of the Code regarding the withholding of payments in respect of
Federal income taxes due from Certificate Owners and otherwise comply with the
provisions of this Agreement applicable to it.

                                   ARTICLE VI

                      THE MASTER SERVICER AND THE DEPOSITOR

                  SECTION 6.01.     Liability of the Master Servicer and the
                                    Depositor.

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

                  SECTION 6.02.     Merger or Consolidation of, or Assumption of
                                    the Obligations of, the Master Servicer or
                                    the Depositor.

                  Any entity into which the Master Servicer or Depositor may be
merged or consolidated, or any entity resulting from any merger, conversion or
consolidation to which the Master Servicer or the Depositor shall be a party, or
any corporation succeeding to the business of the Master Servicer or the
Depositor, shall be the successor of the Master Servicer or the Depositor, 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 Master Servicer
shall satisfy all the requirements of Section 7.02 with respect to the
qualifications of a successor Master Servicer.

                  SECTION 6.03.     Limitation on Liability of the Master
                                    Servicer and Others.

                  Neither the Master Servicer or the Depositor nor any of the
directors or officers or employees or agents of the Master Servicer or the
Depositor shall be under any liability to the Trust or the Certificateholders
for any action taken or for refraining from the taking of any action by the
Master Servicer or the Depositor in good faith pursuant to this Agreement, or
for errors in judgment; PROVIDED, HOWEVER, that this provision shall not protect
the Master Servicer, the Depositor or any such Person against any liability
which would otherwise be imposed by reason of its willful misfeasance, bad faith
or negligence in the performance of duties of the Master Servicer or the
Depositor, as the case may be, or by reason of its reckless disregard of its
obligations and duties of the Master Servicer or the Depositor, as the case may
be, hereunder; PROVIDED, FURTHER, that this provision shall not be construed to
entitle the Master Servicer to indemnity in the event that amounts advanced by
the Master Servicer to retire any senior lien exceed Liquidation Proceeds (in
excess of related liquidation expenses) realized with respect to the related
Mortgage Loan. The preceding sentence shall not limit the obligations of the
Master Servicer pursuant to Section 8.05. The Master Servicer and any director
or officer or employee or agent of the Master Servicer may rely in good faith on
any document of any kind PRIMA FACIE properly executed and submitted by any
Person respecting any matters arising hereunder. The Master Servicer and the
Depositor, and any director or officer or employee or agent of the Master
Servicer or the Depositor, shall be indemnified by the Trust and held harmless
against any loss, liability or expense incurred in connection with any legal
action relating to this Agreement or the Certificates, other than any loss,
liability or expense related to any specific Mortgage Loan or Mortgage Loans
(except as any such loss, liability or expense shall be otherwise reimbursable
pursuant to this Agreement) and any loss, liability or expense incurred by
reason of its willful misfeasance, bad faith or negligence in the performance of
duties hereunder


                                      129
<PAGE>


or by reason of its reckless disregard of obligations and duties hereunder. The
Master Servicer or the Depositor may undertake any such action which it may deem
necessary or desirable in respect of this Agreement, and the rights and duties
of the parties hereto and the interests of the Certificateholders hereunder. In
such event, unless the Depositor or the Master Servicer acts without the consent
of Holders of Certificates entitled to at least 51% of the Voting Rights, the
reasonable legal expenses and costs of such action and any liability resulting
therefrom shall be expenses, costs and liabilities of the Trust and the Master
Servicer shall be entitled to be reimbursed therefor from the Collection 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
Collection Account. The Master Servicer's right to indemnity or reimbursement
pursuant to this Section shall survive any resignation or termination of the
Master Servicer pursuant to Section 6.04 or 7.01 with respect to any losses,
expenses, costs or liabilities arising prior to such resignation or termination
(or arising from events that occurred prior to such resignation or termination).
This paragraph shall apply to the Master Servicer solely in its capacity as
Master Servicer hereunder and in no other capacities. Without limiting the
foregoing, the Master Servicer shall undertake to defend any claims against the
Trust Fund, the Trustee and/or itself initiated by a Borrower or otherwise
related to the servicing of any Mortgage Loan.

                  The Master Servicer (except the Trustee if it is required to
succeed the Master Servicer hereunder) indemnifies and holds the Trustee, the
Depositor, the NIMS Insurer and 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 the
Trustee, the Depositor, the NIMS Insurer and any Certificateholder may sustain
in any way related to the failure of the Master Servicer to perform its duties
and service the Mortgage Loans in compliance with the terms of this Agreement.
The Master Servicer shall immediately notify the Trustee, the Depositor, the
NIMS Insurer and 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 Master Servicer shall
assume (with the consent of the Trustee) 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 Master Servicer, the Trustee, the Depositor, the NIMS Insurer and/or
Certificateholder in respect of such claim. The provisions of this paragraph
shall survive the termination of this Agreement and the payment of the
outstanding Certificates.

                  SECTION 6.04.     Master Servicer Not to Resign.

                  Subject to the provisions of Section 7.01 and Section 6.02,
the Master 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 Master Servicer so causing such a conflict being of a type and
nature carried on by the Master Servicer or its subsidiaries or Affiliates at
the date of this Agreement or (ii) upon satisfaction of the following
conditions: (a) the Master Servicer has proposed a successor servicer to the
Trustee and the NIMS Insurer in writing and such proposed successor servicer is
reasonably acceptable to the Trustee and the NIMS Insurer and (b) each Rating
Agency shall have delivered a letter to


                                      130
<PAGE>


the Trustee and the NIMS Insurer prior to the appointment of the successor
servicer stating that the proposed appointment of such successor servicer as
Master 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 Master Servicer shall become effective until such successor
servicer or, in the case of (i) above, the Trustee shall have assumed the Master
Servicer's responsibilities and obligations hereunder or the Trustee shall have
designated, with the consent of the NIMS Insurer, a successor servicer in
accordance with Section 7.02. Any such resignation shall not relieve the Master
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
Master Servicer. Any such determination permitting the resignation of the Master
Servicer pursuant to clause (i) above shall be evidenced by an Opinion of
Counsel to such effect delivered to the Trustee and the NIMS Insurer. Any such
determination permitting the resignation of the Master Servicer shall be
evidenced by an Opinion of Counsel to such effect delivered to the Trustee and
the NIMS Insurer.

                  SECTION 6.05.     Delegation of Duties.

                  In the ordinary course of business, the Master Servicer at any
time may delegate any of its duties hereunder to any Person, including any of
its Affiliates, who agrees to conduct such duties in accordance with standards
comparable to those set forth in Section 3.01. Such delegation shall not relieve
the Master Servicer of its liabilities and responsibilities with respect to such
duties and shall not constitute a resignation within the meaning of Section
6.04. Except as provided in Section 3.02, no such delegation is permitted that
results in the delegee subservicing any Mortgage Loans. The Master Servicer
shall provide the Trustee and the NIMS Insurer with 60 days prior written notice
prior to the delegation of any of its duties to any Person other than any of the
Master Servicer's Affiliates or their respective successors and assigns.

                  SECTION 6.06.     [Reserved].

                  SECTION 6.07.     Inspection.

                  The Master Servicer, in its capacity as Originator and Master
Servicer, shall afford the Trustee and the NIMS Insurer, upon reasonable advance
notice, during normal business hours, access to all records maintained by the
Master Servicer in respect of its rights and obligations hereunder and access to
officers of the Master Servicer responsible for such obligations. Upon request,
the Master Servicer shall furnish to the Trustee and the NIMS Insurer its most
recent publicly available financial statements and such other information
relating to its capacity to perform its obligations under this Agreement.

                  (v)      A Delinquency Master Servicer Termination Trigger has
         occurred and is continuing;

                  (b)      then, and in each and every such case, so long as a
Master Servicer Event of Termination shall not have been remedied within the
applicable grace period, (x) with respect solely to clause (i)(A) above, if such
Advance is not made by 5:00 P.M., New York time, on the Business Day immediately
following the Master Servicer Remittance Date (provided the Trustee shall give
the Master Servicer notice of such failure to advance by 5:00 P.M. New York time
on the Master Servicer Remittance Date), the Trustee shall, at the direction of
the NIMS Insurer, terminate all of the rights and obligations of the Master
Servicer under this Agreement and the Trustee, or a successor servicer appointed
in accordance with Section 7.02, shall immediately make such Advance and assume,
pursuant to Section 7.02, the duties of a successor Master Servicer, (y) in the
case of (i)(B), (ii), (iii) and (iv) above, the Trustee shall, at the written
direction of the NIMS Insurer or the Holders of each Class of Regular
Certificates evidencing Percentage Interests aggregating not less than 51%, by
notice then given in writing to the Master Servicer and to the Trustee and (z)
in the case of (v) above, the Trustee shall, at the direction of the NIMS
Insurer, by notice then given in writing to the Master Servicer and to the
Trustee, terminate all of the rights and obligations of the Master Servicer as
servicer under this Agreement. Any such notice to the Master Servicer shall also
be given to each Rating Agency, the Depositor and the Originator. On or after
the receipt by the Master Servicer (and by the Trustee if such notice is given
by the Holders) of such written notice, all authority and power of the Master
Servicer under this Agreement, whether with respect to the Certificates or the
Mortgage Loans or otherwise, shall pass to and be vested in the Trustee pursuant
to and under this Section; and, without limitation, and the Trustee is hereby
authorized and empowered to execute and deliver, on behalf of the Master
Servicer, as attorney-in-fact or otherwise, any and all documents and other
instruments, and to do or accomplish all other acts or things necessary or
appropriate to effect the purposes of such notice of termination, whether to
complete the transfer and endorsement of each Mortgage Loan and related
documents or otherwise. The Master Servicer agrees to cooperate with the Trustee
(or the applicable successor Master Servicer) in effecting the termination of
the responsibilities and rights of the Master Servicer hereunder, including,
without limitation, the delivery to the Trustee of all documents and records
requested by it to enable it to assume the Master Servicer's functions under
this Agreement within ten Business Days subsequent to such notice, the transfer
within one Business Day subsequent to such notice to the Trustee (or the
applicable successor Master Servicer) for the administration by it of all cash
amounts that shall at the time be held by the Master Servicer and to be
deposited by it in the Collection Account, the Distribution Account, any REO
Account or any Servicing Account or that have been deposited by the Master
Servicer in such accounts or thereafter received by the Master Servicer with
respect to the Mortgage Loans or any REO Property received by the Master
Servicer. All reasonable costs and expenses (including attorneys' fees) incurred
in connection with transferring the Mortgage Files to the successor Master
Servicer and amending this Agreement to reflect such succession as Master
Servicer pursuant to this Section shall be paid by the predecessor Master
Servicer (or if the predecessor Master Servicer is the Trustee, the initial
Master Servicer) upon presentation of reasonable documentation of such costs and
expenses and to the extent not paid by the Master Servicer, by the Trust.

                  (c)      In connection with any failure by the Master Servicer
to make any remittance required to be made by the Master Servicer to the
Distribution Account pursuant to this Section 7.01 on the day and by the time
such remittance is required to be made under the


                                      133
<PAGE>


terms of this Section 7.01 (without giving effect to any grace or cure period),
the Master Servicer shall pay to the Trustee for the account of the Trustee
interest at the Prime Rate on any amount not timely remitted from and including
the day such remittance was required to be made to, but not including, the day
on which such remittance was actually made.

                  SECTION 7.02.     Trustee to Act; Appointment of Successor.

                  (a)      From the time the Master Servicer (and the Trustee,
if notice is sent by the Holders) receives a notice of termination pursuant to
Section 7.01 or 6.04, the Trustee (or such other successor Master Servicer as is
approved in accordance with this Agreement) shall be the successor in all
respects to the Master Servicer in its capacity as servicer under this Agreement
and the transactions set forth or provided for herein and shall be subject to
all the responsibilities, duties and liabilities relating thereto placed on the
Master Servicer by the terms and provisions hereof arising on and after its
succession. Notwithstanding the foregoing, the parties hereto agree that the
Trustee, in its capacity as successor Master Servicer, immediately will assume
all of the obligations of the Master Servicer to make advances. Notwithstanding
the foregoing, the Trustee, in its capacity as successor Master Servicer, shall
not be responsible for the lack of information and/or documents that it cannot
obtain through reasonable efforts. It is understood and acknowledged by the
parties hereto that there will be a period of transition (not to exceed 90 days)
before the transition of servicing obligations is fully effective. As
compensation therefor, the Trustee (or such other successor Master Servicer)
shall be entitled to such compensation as the Master Servicer would have been
entitled to hereunder if no such notice of termination had been given.
Notwithstanding the above, (i) if the Trustee is unwilling to act as successor
Master Servicer or (ii) if the Trustee is legally unable so to act, the Trustee
shall appoint or petition a court of competent jurisdiction to appoint, any
established housing and home finance institution, bank or other mortgage loan or
home equity loan servicer having a net worth of not less than $50,000,000 as the
successor to the Master Servicer hereunder in the assumption of all or any part
of the responsibilities, duties or liabilities of the Master Servicer hereunder;
PROVIDED, that the appointment of any such successor Master Servicer shall be
approved by the NIMS Insurer (such approval not to be unreasonably withheld), as
evidenced by the prior written consent of the NIMS Insurer, and will not result
in the qualification, reduction or withdrawal of the ratings assigned to the
Certificates by the Rating Agencies as evidenced by a letter to such effect from
the Rating Agencies. Pending appointment of a successor to the Master Servicer
hereunder, unless the Trustee is prohibited by law from so acting, the Trustee
shall act in such capacity as hereinabove provided. In connection with such
appointment and assumption, the successor shall be entitled to receive
compensation out of payments on Mortgage Loans in an amount equal to the
compensation which the Master Servicer would otherwise have received pursuant to
Section 3.18 (or such other compensation as the Trustee and such successor shall
agree, not to exceed the Servicing Fee). The appointment of a successor Master
Servicer shall not affect any liability of the predecessor Master Servicer which
may have arisen under this Agreement prior to its termination as Master Servicer
to pay any deductible under an insurance policy pursuant to Section 3.14 or to
indemnify the Trustee or the NIMS Insurer pursuant to Section 6.03), nor shall
any successor Master Servicer be liable for any acts or omissions of the
predecessor Master Servicer or for any breach by such Master Servicer of any of
its representations or warranties contained herein or in any related document or
agreement. The Trustee and such successor shall take such action, consistent
with this Agreement, as shall be necessary to effectuate any such succession.
All Servicing Transfer Costs shall be paid by the predecessor Master Servicer
upon presentation of reasonable documentation of such costs, and if such
predecessor Master Servicer


                                      134
<PAGE>


defaults in its obligation to pay such costs, such costs shall be paid by the
successor Master Servicer or the Trustee (in which case the successor Master
Servicer or the Trustee, as applicable, shall be entitled to reimbursement
therefor from the assets of the Trust).

                  (b)      Any successor to the Master Servicer, including the
Trustee, shall during the term of its service as servicer continue to service
and administer the Mortgage Loans for the benefit of Certificateholders, and
maintain in force a policy or policies of insurance covering errors and
omissions in the performance of its obligations as Master Servicer hereunder and
a Fidelity Bond in respect of its officers, employees and agents to the same
extent as the Master Servicer is so required pursuant to Section 3.14.

                  SECTION 7.03.     Waiver of Defaults.

                  The Majority Certificateholders may, on behalf of all
Certificateholders and with the consent of the NIMS Insurer, waive any events
permitting removal of the Master Servicer as servicer pursuant to this Article
VII, PROVIDED, HOWEVER, that the Majority Certificateholders may not waive a
default in making a required distribution on a Certificate without the consent
of the Holder of such Certificate and the consent of the NIMS Insurer. Upon any
waiver of a past default, such default shall cease to exist and any Master
Servicer Event of Termination arising therefrom shall be deemed to have been
remedied for every purpose of this Agreement. No such waiver shall extend to any
subsequent or other default or impair any right consequent thereto except to the
extent expressly so waived. Notice of any such waiver shall be given by the
Trustee to the Rating Agencies and the NIMS Insurer.

                  SECTION 7.04.     Notification to Certificateholders.

                  (a)      Upon any termination or appointment of a successor to
the Master Servicer pursuant to this Article VII or Section 6.04, the Trustee
shall give prompt written notice thereof to the Certificateholders at their
respective addresses appearing in the Certificate Register, the NIMS Insurer and
each Rating Agency.

                  (b)      No later than 60 days after the occurrence of any
event which constitutes or which, with notice or a lapse of time or both, would
constitute a Master Servicer Event of Termination for five Business 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 Certificateholders and to the
NIMS Insurer notice of such occurrence unless such default or Master Servicer
Event of Termination shall have been waived or cured.

                  SECTION 7.05.     Survivability of Master Servicer
                                    Liabilities.

                  Notwithstanding anything herein to the contrary, upon
termination of the Master Servicer hereunder, any liabilities of the Master
Servicer which accrued prior to such termination shall survive such termination.

                                   THE TRUSTEE

                  SECTION 8.01.     Duties of Trustee.

                  The Trustee, prior to the occurrence of a Master Servicer
Event of Termination and after the curing of all Master Servicer Events of
Termination which may have occurred, undertakes to perform such duties and only
such duties as are specifically set forth in this Agreement. If a Master
Servicer Event of Termination has occurred (which has not been cured) of which a
Responsible Officer has knowledge, 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 man would exercise or use under the
circumstances in the conduct of his own affairs.

                  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 to the requirements of this Agreement; provided, however, that the
Trustee will not be responsible for the accuracy or content of any such
resolutions, certificates, statements, opinions, reports, documents or other
instruments. If any such instrument is found not to conform 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 the Trustee's satisfaction, the Trustee will provide notice thereof
to the Certificateholders and the NIMS Insurer.

                  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 Master Servicer Event of
         Termination, and after the curing of all such Master Servicer Events of
         Termination 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 and
         conforming 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 of the
         Trustee, unless it shall be proved that the Trustee was negligent in
         ascertaining or investigating the facts related thereto;

                  (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 NIMS Insurer or the
         Majority Certificateholders relating to the time, method and place of


                                      136
<PAGE>


         conducting any proceeding for any remedy available to the Trustee, or
         exercising or omitting to exercise any trust or power conferred upon
         the Trustee, under this Agreement; and

                  (iv)     the Trustee shall not be charged with knowledge of
         any failure by the Master Servicer to comply with the obligations of
         the Master Servicer referred to in clauses (i) and (ii) of Section
         7.01(a) unless a Responsible Officer of the Trustee at the Corporate
         Trust Office obtains actual knowledge of such failure or the Trustee
         receives written notice of such failure from the Master Servicer, the
         NIMS Insurer or the Majority Certificateholders.

                  The Trustee shall not be required to expend or risk its own
funds or otherwise incur financial liability in the performance of any of its
duties hereunder, or in the exercise of any of its rights or powers, if there is
reasonable ground for believing that the repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it, and
none of the provisions contained in this Agreement shall in any event require
the Trustee to perform, or be responsible for the manner of performance of, any
of the obligations of the Master Servicer under this Agreement, except during
such time, if any, as the Trustee shall be the successor to, and be vested with
the rights, duties, powers and privileges of, the Master Servicer in accordance
with the terms of this Agreement.

                  The Depositor hereby directs the Trustee to execute, deliver
and perform its obligations under the related Cap Contract on the Closing Date
and thereafter on behalf of the Holders of the Group I Certificates, the Group
II Certificates and the Mezzanine Certificates. The Seller, the Depositor, the
Master Servicer and the Holders of the Group I Certificates, the Group II
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 related Cap Contract and shall do so solely in
its capacity as Trustee of the Trust Fund and not in its individual capacity.

                  SECTION 8.02.     Certain Matters Affecting the Trustee.

                  Except as otherwise provided in Section 8.01:

                  (i)      the Trustee may request and rely upon, and shall be
         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, and the manner of obtaining consents and
         of evidencing the authorization of the execution thereof by
         Certificateholders shall be subject to such reasonable regulations as
         the Trustee may prescribe;

                  (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;


                                      137
<PAGE>


                  (iii)    the Trustee shall be under no obligation to exercise
         any of the rights or powers vested in it by this Agreement, or to
         institute, conduct or defend any litigation hereunder or in relation
         hereto, at the request, order or direction of any of the
         Certificateholders or the NIMS Insurer, pursuant to the provisions of
         this Agreement, unless such Certificateholders or the NIMS Insurer, as
         applicable, shall have offered to the Trustee reasonable security or
         indemnity against the costs, expenses and liabilities which may be
         incurred therein or thereby; the right of the Trustee to perform any
         discretionary act enumerated in this Agreement shall not be construed
         as a duty, and the Trustee shall not be answerable for other than its
         negligence or willful misconduct in the performance of any such act;

                  (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 Master Servicer Event of
         Termination and after the curing of all Master Servicer Events of
         Termination 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
         documents, unless requested in writing to do so by the NIMS Insurer or
         the Majority Certificateholder; 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 the security afforded to it by the terms of this
         Agreement, the Trustee may require reasonable indemnity against such
         cost, expense or liability as a condition to such proceeding. The
         reasonable expense of every such examination shall be paid by the
         Master Servicer or the NIMS Insurer (if requested by the NIMS Insurer)
         or, if paid by the Trustee, shall be reimbursed by the Master Servicer
         or the NIMS Insurer (if requested by the NIMS Insurer) upon demand and,
         if not reimbursed by the Master Servicer or the NIMS Insurer (if
         requested by the NIMS Insurer), shall be reimbursed by the Trust.
         Nothing in this clause (v) shall derogate from the obligation of the
         Master Servicer to observe any applicable law prohibiting disclosure of
         information regarding the Mortgagors;

                  (vi)     the Trustee shall not be accountable, shall have no
         liability and makes no representation as to any acts or omissions
         hereunder of the Master Servicer until such time as the Trustee may be
         required to act as Master Servicer pursuant to Section 7.02 and
         thereupon only for the acts or omissions of the Trustee as successor
         Master Servicer;

                  (vii)    the Trustee may execute any of the trusts or powers
         hereunder or perform any duties hereunder either directly or by or
         through agents or attorneys or a custodian; and

                  (viii)   the right of the Trustee to perform any discretionary
         act enumerated in this Agreement shall not be construed as a duty, and
         the Trustee shall not be answerable for other than its negligence or
         willful misconduct in the performance of such act.

                  SECTION 8.03.     Trustee Not Liable for Certificates or
                                    Mortgage Loans.

                  The recitals contained herein and in the Certificates (other
than the authentication of the Trustee on the Certificates) shall be taken as
the statements of the Depositor, and the Trustee assumes no responsibility for
the correctness of the same. The Trustee makes no representations as to the
validity or sufficiency of this Agreement or of the Certificates (other than the
signature and authentication of the Trustee on the Certificates) or of any
Mortgage Loan or related document. The Trustee shall not be accountable for the
use or application by the Master Servicer, or for the use or application of any
funds paid to the Master Servicer in respect of the Mortgage Loans or deposited
in or withdrawn from the Collection Account by the Master Servicer. The Trustee
shall at no time have any responsibility or liability for or with respect to the
legality, validity and enforceability of any Mortgage or any Mortgage Loan, or
the perfection and priority of any Mortgage or the maintenance of any such
perfection and priority, or for or with respect to the sufficiency of the Trust
or its ability to generate the payments to be distributed to Certificateholders
under this Agreement, including, without limitation: the existence, condition
and ownership of any Mortgaged Property; the existence and enforceability of any
hazard insurance thereon (other than if the Trustee shall assume the duties of
the Master Servicer pursuant to Section 7.02); the validity of the assignment of
any Mortgage Loan to the Trustee or of any intervening assignment; the
completeness of any Mortgage Loan; the performance or enforcement of any
Mortgage Loan (other than if the Trustee shall assume the duties of the Master
Servicer pursuant to Section 7.02); the compliance by the Depositor, the
Originator, the Seller or the Master Servicer with any warranty or
representation made under this Agreement or in any related document or the
accuracy of any such warranty or representation prior to the Trustee's receipt
of notice or other discovery of any non-compliance therewith or any breach
thereof; any investment of monies by or at the direction of the Master Servicer
or any loss resulting therefrom, it being understood that the Trustee shall
remain responsible for any Trust property that it may hold in its individual
capacity; the acts or omissions of any of the Master Servicer (other than if the
Trustee shall assume the duties of the Master Servicer pursuant to Section
7.02), any Sub-Servicer or any Mortgagor; any action of the Master Servicer
(other than if the Trustee shall assume the duties of the Master Servicer
pursuant to Section 7.02), or any Sub-Servicer taken in the name of the Trustee;
the failure of the Master Servicer or any Sub-Servicer to act or perform any
duties required of it as agent of the Trustee hereunder; or any action by the
Trustee taken at the instruction of the Master Servicer (other than if the
Trustee shall assume the duties of the Master Servicer pursuant to Section
7.02); PROVIDED, HOWEVER, that the foregoing shall not relieve the Trustee of
its obligation to perform its duties under this Agreement, including, without
limitation, the Trustee's duty to review the Mortgage Files pursuant to Section
2.01. The Trustee shall have no responsibility for filing any financing or
continuation statement in any public office at any time or to otherwise perfect
or maintain the perfection of any security interest or lien granted to it
hereunder (unless the Trustee shall have become the successor Master Servicer).

                  SECTION 8.04.     Trustee May Own Certificates.

                  The Trustee in its individual or any other capacity may become
the owner or pledgee of Certificates with the same rights as it would have if it
were not Trustee and may transact any banking and trust business with the
Originator, the Master Servicer, the Depositor or their Affiliates.

                  SECTION 8.05.     Trustee Fee and Expenses.

                  (a)      The Trustee shall withdraw from the Distribution
Account on each Distribution Date and pay to itself the Trustee Fee. The Trustee
shall be reimbursed from the Trust Fund for all reasonable expenses,
disbursements and advances incurred or made by the Trustee in accordance with
any of the provisions of this Agreement (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)
up to a limit of $25,000 per calendar year except any such expense, disbursement
or advance as may arise from its negligence or bad faith or which is the
responsibility of Certificateholders or the Trustee hereunder. In addition, the
Trustee and its officers, directors, employees and agents shall be entitled to
be indemnified for, and held harmless by the Trust Fund against, any and all
losses, liabilities, damages, claims or expenses incurred in connection with any
legal action relating to this Agreement or the Certificates up to a limit of
$600,000 per calendar year, other than (i) any loss, liability or expense
incurred by reason of willful misfeasance, bad faith or negligence of the
Trustee in the performance of its duties hereunder or by reason of the Trustee's
reckless disregard of obligations and duties hereunder or (ii) resulting from a
breach of the Master Servicer's obligations and duties under this Agreement and
the Mortgage Loans (for which the Master Servicer shall indemnify pursuant to
Section 8.05(b)). This section shall survive termination of this Agreement or
the resignation or removal of any Trustee hereunder.

                  (b)      The Master Servicer agrees to indemnify the Trustee
from, and hold it harmless against, any loss, liability or expense resulting
from a breach of the Master 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 Master Servicer to the Trustee shall be from the Master Servicer's
own funds, without reimbursement from the Trust Fund therefor.

                  (c)      Any amounts payable to the Trustee, or any director,
officer, employee or agent of the Trustee in respect of the indemnification
provided by this Section 8.05, 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 Distribution Account at any time.

                  (d)      The limitations on the indemnification provided to
the Trustee set forth in Section 8.05(a) above shall remain in effect for so
long as any series of notes issued pursuant to one or more Indentures, as set
forth in Section 1.04 remain outstanding.

                  SECTION 8.06.     Eligibility Requirements for Trustee.

                  The Trustee hereunder shall at all times be an entity duly
organized and validly existing under the laws of the United States of America or
any state thereof, authorized under such laws to exercise corporate trust
powers, having a combined capital and surplus of at least $50,000,000 and a
long-term debt rating of at least "A-" and a short-term debt rating of at least
"A-1" by S&P, if rated by S&P, and subject to supervision or examination by
federal or state authority. If such entity publishes reports of condition at
least annually, pursuant to law or to the requirements of the aforesaid
supervising or examining authority, then for the purposes of this


                                      140
<PAGE>


Section 8.06, the combined capital and surplus of such entity shall be deemed to
be its combined capital and surplus as set forth in its most recent report of
condition so published. The principal office of the Trustee (other than the
initial Trustee) shall be in a state with respect to which an Opinion of Counsel
has been delivered to such Trustee and the NIMS Insurer at the time such Trustee
is appointed Trustee to the effect that the Trust will not be a taxable entity
under the laws of such state. In case at any time the Trustee shall cease to be
eligible in accordance with the provisions of this Section 8.06, the Trustee
shall resign immediately in the manner and with the effect specified in Section
8.07.

                  SECTION 8.07.     Resignation or Removal of Trustee.

                  The Trustee may at any time resign and be discharged from the
trusts hereby created by giving written notice thereof to the NIMS Insurer, the
Depositor, the Master Servicer and each Rating Agency. Upon receiving such
notice of resignation, the Depositor shall promptly appoint a successor Trustee
acceptable to the NIMS Insurer by written instrument, in duplicate, one copy of
which instrument shall be delivered to the resigning Trustee and one copy to the
successor Trustee. If no successor Trustee shall have been so appointed and
having accepted appointment within 30 days after the giving of such notice of
resignation, the resigning 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 the NIMS Insurer or if at any time
the Trustee shall be legally unable to act, or shall be adjudged a 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, the Master Servicer or the NIMS Insurer may
remove the Trustee. If the Depositor, the Master Servicer or the NIMS Insurer
removes the Trustee under the authority of the immediately preceding sentence,
the Depositor, with the consent of the NIMS Insurer, shall promptly appoint a
successor Trustee by written instrument, in duplicate, one copy of which
instrument shall be delivered to the Trustee so removed and one copy to the
successor trustee.

                  The Majority Certificateholders (or the NIMS Insurer upon the
failure of the Trustee to perform its obligations hereunder) may at any time
remove the Trustee by written instrument or instruments delivered to the Master
Servicer, the Depositor and the Trustee; the Depositor shall thereupon use its
best efforts to appoint a successor trustee acceptable to the NIMS Insurer in
accordance with this Section.

                  Any resignation or removal of the Trustee and appointment of a
successor Trustee pursuant to any of the provisions of this Section 8.07 shall
not become effective until acceptance of appointment by the successor Trustee as
provided in Section 8.08.

                  SECTION 8.08.     Successor Trustee.

                  Any successor Trustee appointed as provided in Section 8.07
shall execute, acknowledge and deliver to the NIMS Insurer, the Depositor, the
Master Servicer and to its predecessor Trustee an instrument accepting such
appointment hereunder, and thereupon the


                                      141
<PAGE>


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 like effect as if originally named as Trustee. The
Depositor, the Master Servicer and the predecessor Trustee shall execute and
deliver such instruments and do such other things as may reasonably be required
for fully and certainly vesting and confirming in the successor Trustee all such
rights, powers, duties and obligations.

                  No successor Trustee shall accept appointment as provided in
this Section 8.08 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 the Regular
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 8.08, the successor Trustee shall mail notice of the
appointment of a successor Trustee hereunder to all Holders of Certificates at
their addresses as shown in the Certificate Register and to each Rating Agency.

                  SECTION 8.09.     Merger or Consolidation of Trustee.

                  Any entity into which the Trustee may be merged or converted
or with which it may be consolidated, or any entity resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any entity
succeeding to the business of the Trustee, shall be the successor of the Trustee
hereunder, provided such entity shall be eligible under the provisions of
Section 8.06 and 8.08, 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.

                  Notwithstanding any other provisions of this Agreement, at any
time, for the purpose of meeting any legal requirements of any jurisdiction in
which any part of the Trust or any Mortgaged Property may at the time be
located, the Depositor and the Trustee acting jointly shall have the power and
shall execute and deliver all instruments to appoint one or more Persons
approved by the Trustee and the NIMS Insurer to act as co-trustee or
co-trustees, jointly with the Trustee, or separate trustee or separate trustees,
of all or any part of the Trust, and to vest in such Person or Persons, in such
capacity and for the benefit of the Certificateholders, such title to the Trust,
or any part thereof, and, subject to the other provisions of this Section 8.10,
such powers, duties, obligations, rights and trusts as the Master 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 Master Servicer and the
NIMS Insurer. If the Master Servicer and the NIMS Insurer shall not have joined
in such appointment within 15 days after the receipt by it of a request so to
do, or in the case a Master Servicer Event of Termination 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, and no
notice to Certificateholders of the appointment of any co-trustee or separate
trustee shall be required under Section 8.08. The Master Servicer shall be
responsible for the fees of any co-trustee or separate trustee appointed
hereunder.

<PAGE>


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

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

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

                  (iii)    the Master Servicer and the Trustee, acting jointly
         and with the consent of the NIMS Insurer, may at any time accept the
         resignation of or remove any separate trustee or co-trustee except that
         following the occurrence of a Master Servicer Event of Termination, the
         Trustee acting alone may accept the resignation or remove any separate
         trustee or co-trustee.

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

                  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.     Limitation of Liability.

                  The Certificates are executed by the Trustee, not in its
individual capacity but solely as Trustee of the Trust, in the exercise of the
powers and authority conferred and vested in it by this Agreement. Each of the
undertakings and agreements made on the part of the Trustee


                                      143
<PAGE>


in the Certificates is made and intended not as a personal undertaking or
agreement by the Trustee but is made and intended for the purpose of binding
only the Trust.

                  SECTION 8.12.     Trustee May Enforce Claims Without
                                    Possession of Certificates.

                  (a)      All rights of action and claims under this Agreement
or the Certificates may be prosecuted and enforced by the Trustee without the
possession of any of the Certificates or the production thereof in any
proceeding relating thereto, and such proceeding instituted by the Trustee shall
be brought in its own name or in its capacity as Trustee for the benefit of all
Holders of such Certificates, subject to the provisions of this Agreement. Any
recovery of judgment shall, after provision for the payment of the reasonable
compensation, expenses, disbursement and advances of the Trustee, its agents and
counsel, be for the ratable benefit of the Certificateholders in respect of
which such judgment has been recovered.

                  (b)      The Trustee shall afford the Seller, the Originator,
the Depositor, the Master Servicer, the NIMS Insurer and each Certificate Owner
upon reasonable notice during normal business hours, access to all records
maintained by the Trustee in respect of its duties hereunder and access to
officers of the Trustee responsible for performing such duties. Upon request,
the Trustee shall furnish the Depositor, the Master Servicer, the NIMS Insurer
and any requesting Certificate Owner with its most recent financial statements.
The Trustee shall cooperate fully with the Seller, the Originator the Master
Servicer, the Depositor and such Certificate Owner and shall make available to
the Seller, the Originator, the Master Servicer, the Depositor, the NIMS Insurer
and such Certificate Owner for review and copying such books, documents or
records as may be requested with respect to the Trustee's duties hereunder. The
Seller, the Originator, the Depositor, the Master Servicer and the Certificate
Owners shall not have any responsibility or liability for any action or failure
to act by the Trustee and are not obligated to supervise the performance of the
Trustee under this Agreement or otherwise.

                  SECTION 8.13.     Suits for Enforcement.

                  In case a Master Servicer Event of Termination or other
default by the Master Servicer or the Depositor hereunder shall occur and be
continuing, the Trustee, shall, at the direction of the Majority
Certificateholders or the NIMS Insurer, or may, proceed to protect and enforce
its rights and the rights of the Certificateholders or the NIMS Insurer under
this Agreement by a suit, action or proceeding in equity or at law or otherwise,
whether for the specific performance of any covenant or agreement contained in
this Agreement or in aid of the execution of any power granted in this Agreement
or for the enforcement of any other legal, equitable or other remedy, as the
Trustee, being advised by counsel, and subject to the foregoing, shall deem most
effectual to protect and enforce any of the rights of the Trustee, the NIMS
Insurer and the Certificateholders.

                  SECTION 8.14.     Waiver of Bond Requirement.

                  The Trustee shall be relieved of, and each Certificateholder
hereby waives, any requirement of any jurisdiction in which the Trust, or any
part thereof, may be located that the Trustee post a bond or other surety with
any court, agency or body whatsoever.

                                    Appraisal Requirement.

                  The Trustee shall be relieved of, and each Certificateholder
hereby waives, any requirement of any jurisdiction in which the Trust, or any
part thereof, may be located that the Trustee file any inventory, accounting or
appraisal of the Trust with any court, agency or body at any time or in any
manner whatsoever.

                              REMIC ADMINISTRATION

                  SECTION 9.01.     REMIC Administration.

                  (a)      REMIC elections as set forth in the Preliminary
Statement shall be made by the Trustee on Form 1066 or other appropriate federal
tax or information return for the taxable year ending on the last day of the
calendar year in which the Certificates are issued. The regular interests and
residual interest in each REMIC shall be as designated in the Preliminary
Statement.

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

                  (c)      The Master Servicer shall pay any and all tax related
expenses (not including taxes) of each REMIC, including but not limited to any
professional fees or expenses related to audits or any administrative or
judicial proceedings with respect to each REMIC that involve the Internal
Revenue Service or state tax authorities, but only to the extent that (i) such
expenses are ordinary or routine expenses, including expenses of a routine audit
but not expenses of litigation (except as described in (ii)); or (ii) such
expenses or liabilities (including taxes and penalties) are attributable to the
negligence or willful misconduct of the Master Servicer in fulfilling its duties
hereunder. The Master Servicer shall be entitled to reimbursement of expenses to
the extent provided in clause (i) above from the Collection Account.

                  (d)      The Trustee shall prepare, sign and file, all of the
REMICs' federal and state tax and information returns as the direct
representative each REMIC created hereunder. The expenses of preparing and
filing such returns shall be borne by the Trustee. The Trustee shall use the Tax
Prepayment Assumption for purposes of computing any tax reporting, including,
but not limited to, the calculation of the original issue discount.

                  (e)      The Holder of the Residual Certificate at any time
holding the largest Percentage Interest thereof shall be the "tax matters
person" as defined in the REMIC Provisions (the "Tax Matters Person") with
respect to the related REMIC and shall act as Tax Matters Person for each REMIC.
The Trustee, as agent for the Tax Matters Person, shall perform on behalf of
each 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, if required by the Code, the REMIC
Provisions, or other such guidance, the Trustee, as agent for the Tax Matters
Person, shall provide (i) to the Treasury or other governmental authority such
information as is necessary for the application of any tax relating to the
transfer of a Residual Certificate to any disqualified person or organization
and (ii) to the Certificateholders such information or reports as are required
by the Code or REMIC Provisions. The Trustee, as agent for the Tax Matters
Person, shall represent each REMIC in any administrative or judicial proceedings
relating to an examination or audit by any governmental taxing authority,
request an administrative adjustment as to any taxable year of any REMIC, enter
into settlement agreements with any government taxing agency, extend any statute
of limitations relating to any item of any


                                      146
<PAGE>


REMIC and otherwise act on behalf of any REMIC in relation to any tax matter
involving the Trust.

                  (f)      The Trustee, the Master Servicer and the Holders of
Certificates shall take any action or cause the REMIC to take any action
necessary to create or maintain the status of each REMIC as a REMIC under the
REMIC Provisions and shall assist each other as necessary to create or maintain
such status. Neither the Trustee, the Master Servicer nor the Holder of any
Residual Certificate shall take any action, cause any REMIC created hereunder 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 such REMIC as a REMIC or (ii) result in the imposition of
a tax upon such REMIC (including but not limited to the tax on prohibited
transactions as defined in Code Section 860F(a)(2) and the tax on prohibited
contributions set forth on Section 860G(d) of the Code) (either such event, an
"Adverse REMIC Event") unless the Trustee, the NIMS Insurer and the Master
Servicer have received an Opinion of Counsel (at the expense of the party
seeking to take such action) to the effect that the contemplated action will not
endanger such status or result in the imposition of such a tax. In addition,
prior to taking any action with respect to any REMIC created hereunder or the
assets therein, or causing such REMIC to take any action, which is not expressly
permitted under the terms of this Agreement, any Holder of a Residual
Certificate will consult with the Trustee, the NIMS Insurer and the Master
Servicer, or their respective designees, in writing, with respect to whether
such action could cause an Adverse REMIC Event to occur with respect to any
REMIC, and no such Person shall take any such action or cause any REMIC to take
any such action as to which the Trustee, the NIMS Insurer or the Master Servicer
has advised it in writing that an Adverse REMIC Event could occur.

                  (g)      Each Holder of a Residual Certificate shall pay when
due any and all taxes imposed on each REMIC created hereunder by federal or
state governmental authorities. To the extent that such Trust taxes are not paid
by a Residual Certificateholder, the Trustee shall pay any remaining REMIC taxes
out of current or future amounts otherwise distributable to the Holder of the
Residual Certificate in the REMICs or, if no such amounts are available, out of
other amounts held in the Distribution Account, and shall reduce amounts
otherwise payable to Holders of regular interests in the related REMIC. Subject
to the foregoing, in the event that a REMIC incurs a state or local tax,
including franchise taxes, as a result of a determination that such REMIC is
domiciled in the State of California or any other state for state tax purposes
by virtue of the location of the Master Servicer or any subservicer, the Master
Servicer agrees to pay on behalf of such REMIC when due, any and all state and
local taxes imposed as a result of such a determination, in the event that the
Holder of the related Residual Certificate fails to pay such taxes, if any, when
imposed.

                  (h)      The Trustee, as agent for the Tax Matters Person,
shall, for federal income tax purposes, maintain books and records with respect
to each REMIC created hereunder on a calendar year and on an accrual basis.

                  (i)      No additional contributions of assets shall be made
to any REMIC created hereunder, except as expressly provided in this Agreement
with respect to eligible substitute mortgage loans.

<PAGE>


                  (j)      Neither the Trustee nor the Master Servicer shall
enter into any arrangement by which any REMIC created hereunder will receive a
fee or other compensation for services.

                  (k)      On or before April 15 of each calendar year beginning
in 2005, the Master Servicer shall deliver to the NIMS Insurer, the Trustee and
each Rating Agency an Officers' Certificate stating the Master Servicer's
compliance with the provisions of this Section 9.01.

                  (l)      The Trustee will apply for an Employee Identification
Number from the Internal Revenue Service via a Form SS-4 or other acceptable
method for all tax entities and shall complete the Form 8811.

                  SECTION 9.02.     Prohibited Transactions and Activities.

                  Neither the Depositor, the Master Servicer nor the Trustee
shall sell, dispose of, or substitute for any of the Mortgage Loans, except in a
disposition pursuant to (i) the foreclosure of a Mortgage Loan, (ii) the
bankruptcy of the Trust Fund, (iii) the termination of any REMIC created
hereunder pursuant to Article X of this Agreement, (iv) a substitution pursuant
to Article II of this Agreement or (v) a repurchase of Mortgage Loans pursuant
to Article II of this Agreement, nor acquire any assets for any REMIC, nor sell
or dispose of any investments in the Distribution Account for gain, nor accept
any contributions to either REMIC after the Closing Date, unless it and the NIMS
Insurer have received an Opinion of Counsel (at the expense of the party causing
such sale, disposition, or substitution) that such disposition, acquisition,
substitution, or acceptance will not (a) affect adversely the status of any
REMIC created hereunder as a REMIC or of the interests therein other than the
Residual Certificates as the regular interests therein, (b) affect the
distribution of interest or principal on the Certificates, (c) result in the
encumbrance of the assets transferred or assigned to the Trust Fund (except
pursuant to the provisions of this Agreement) or (d) cause any REMIC created
hereunder to be subject to a tax on prohibited transactions or prohibited
contributions pursuant to the REMIC Provisions.

                  SECTION 9.03.     Indemnification with Respect to Certain
                                    Taxes and Loss of REMIC Status.

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


                                      148
<PAGE>


duties and obligations set forth herein, and (3) for any special or
consequential damages to Certificateholders (in addition to payment of principal
and interest on the Certificates).

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

                                   TERMINATION

                  SECTION 10.01.    Termination.

                  (a)      The respective obligations and responsibilities of
the Master Servicer, the Depositor and the Trustee created hereby (other than
the obligation of the Trustee to make certain payments to Certificateholders
after the final Distribution Date and the obligation of the Master Servicer to
send certain notices as hereinafter set forth) shall terminate upon notice to
the Trustee upon the earliest of (i) the Distribution Date on which the
Certificate Principal Balances of the Regular Certificates have been reduced to
zero, (ii) the final payment or other liquidation of the last Mortgage Loan in
the Trust and (iii) the optional purchase by the Master Servicer or the NIMS
Insurer of the Mortgage Loans as described below. Notwithstanding the foregoing,
in no event shall the trust created hereby continue beyond the earlier of (a)
February 2035 or (b) the expiration of 21 years from the death of the last
survivor of the descendants of Joseph P. Kennedy, the late ambassador of the
United States to the Court of St. James's, living on the date hereof.

                  The Master Servicer (or if the Master Servicer fails to
exercise such option, the NIMS Insurer) may, at its option (the party exercising
such right the "Terminator"), terminate this Agreement on any date on which the
aggregate of the Stated Principal Balances of the Mortgage Loans (after giving
effect to scheduled payments of principal due during the related Due Period, to
the extent received or advanced, and unscheduled collections of principal
received during the related Prepayment Period) on such date is equal to or less
than 10% of the sum of the aggregate Stated Principal Balances of the Initial
Mortgage Loans on the Cut-off Date and the Original Pre-Funded Amounts, by
purchasing, on the next succeeding Distribution Date, all of the outstanding
Mortgage Loans and REO Properties at a price equal to the fair market value of
the Mortgage Loans and REO Properties (as determined by the Master Servicer, if
it is the Terminator, the NIMS Insurer, if it is 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,
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
Certificateholders pursuant to Section 10.01(c)), 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, any accrued and unpaid Net WAC Rate Carryover
Amount, any previously unpaid Allocated Realized Loss Amounts (the "Termination
Price"); provided, however, such option may only be exercised if (i) 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
secured by the Class C Certificates and the Class P Certificates and issued
pursuant to the Indenture and any amounts owed to the NIMS Insurer at the time
the option is exercised, and (ii) the fair market value of the Mortgage Loans
and REO Properties determined as provided above is at least equal to the Stated
Principal Balance of the Mortgage Loans (after giving effect to scheduled
payments of principal due during the related Due Period, to the extent received
or advanced, and unscheduled collections of principal received during the
related Prepayment Period) and the appraised value of the REO Properties.
Notwithstanding the foregoing, if the condition set forth in clause (i) above is
satisfied but the condition set forth in


                                      150
<PAGE>


clause (ii) above is not satisfied, then if the Terminator is the Master
Servicer or the NIMS Insurer, such Terminator may nevertheless exercise such
option by paying a higher Termination Price equal to the Stated Principal
Balance of the Mortgage Loans (after giving effect to scheduled payments of
principal due during the related Due Period, to the extent received or advanced,
and unscheduled collections of principal received during the related Prepayment
Period) and the appraised value of the REO Properties 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, any accrued and unpaid Net WAC Rate Carryover
Amount, any previously unpaid Allocated Realized Loss Amounts, provided that the
payment of such higher Termination Price is not prohibited by any regulatory
institution under whose supervision such Terminator may be conducting its
business at such time.

                  In connection with any such purchase pursuant to the preceding
paragraph, the Master Servicer or the NIMS Insurer, as applicable, shall deposit
in the Distribution Account all amounts then on deposit in the Collection
Account, which deposit shall be deemed to have occurred immediately preceding
such purchase.

                  Any such purchase shall be accomplished by deposit into the
Distribution Account on the Determination Date before such Distribution Date of
the Termination Price.

                  (b)      Notice of any termination, specifying the
Distribution Date (which shall be a date that would otherwise be a Distribution
Date) upon which the Certificateholders may surrender their Certificates to the
Trustee for payment of the final distribution and cancellation, shall be given
promptly by the Trustee upon the Trustee receiving notice of such date from the
Master Servicer or the NIMS Insurer, by letter to the Certificateholders and the
NIMS Insurer mailed not earlier than the 15th day and not later than the 25th
day of the month next preceding the month of such final distribution specifying
(1) the Distribution Date upon which final distribution of the Certificates will
be made upon presentation and surrender of such Certificates at the office or
agency of the Trustee therein designated, (2) the amount of any such final
distribution and (3) that the Record Date otherwise applicable to such
Distribution Date is not applicable, distributions being made only upon
presentation and surrender of the Certificates at the office or agency of the
Trustee therein specified.

                  (c)      Upon presentation and surrender of the Certificates,
the Trustee shall cause to be distributed to the Holders of the Certificates on
the Distribution Date for such final distribution, in proportion to the
Percentage Interests of their respective Class and to the extent that funds are
available for such purpose, an amount equal to the amount required to be
distributed to such Holders in accordance with the provisions of Section 4.01
for such Distribution Date. By acceptance of the Residual Certificates, the
Holders of the Residual Certificates agree, in connection with any termination
hereunder, to assign and transfer any amounts in excess of the par value of the
Mortgage Loans, and to the extent received in respect of such termination, to
pay any such amounts to the Holders of the Class C Certificates.

                  (d)      In the event that all Certificateholders shall not
surrender their Certificates for final payment and cancellation on or before
such final Distribution Date, the Trustee shall promptly following such date
cause all funds in the Distribution Account not distributed in final
distribution to Certificateholders to be withdrawn therefrom and credited to the
remaining


                                      151
<PAGE>


Certificateholders by depositing such funds in a separate Servicing Account for
the benefit of such Certificateholders, and the Master Servicer (if the Master
Servicer has exercised its right to purchase the Mortgage Loans), the NIMS
Insurer (if the NIMS Insurer has exercised its right to purchase the Mortgage
Loans) or the Trustee (in any other case) shall give a second written notice to
the remaining Certificateholders, to surrender their Certificates for
cancellation and receive the final distribution with respect thereto. If within
nine months after the second notice all the Certificates shall not have been
surrendered for cancellation, the Class R Certificateholder shall be entitled to
all unclaimed funds and other assets which remain subject hereto, and the
Trustee upon transfer of such funds shall be discharged of any responsibility
for such funds, and the Certificateholders shall look to the Class R
Certificateholder for payment.

                  SECTION 10.02.    Additional Termination Requirements.

                  (a)      In the event that the Master Servicer or the NIMS
Insurer exercises its purchase option as provided in Section 10.01, each REMIC
shall be terminated in accordance with the following additional requirements,
unless the Trustee shall have been furnished with an Opinion of Counsel to the
effect that the failure of the Trust to comply with the requirements of this
Section will not (i) result in the imposition of taxes on "prohibited
transactions" of the Trust as defined in Section 860F of the Code or (ii) cause
any REMIC constituting part of the Trust Fund to fail to qualify as a REMIC at
any time that any Certificates are outstanding:

                  (i)      Within 90 days prior to the final Distribution Date,
         the Master Servicer or the NIMS Insurer shall adopt and the Trustee
         shall sign a plan of complete liquidation of each REMIC created
         hereunder meeting the requirements of a "Qualified Liquidation" under
         Section 860F of the Code and any regulations thereunder; and

                  (ii)     At or after the time of adoption of such a plan of
         complete liquidation and at or prior to the final Distribution Date,
         the Trustee shall sell all of the assets of the Trust Fund to the
         Master Servicer or the NIMS Insurer, as applicable, for cash pursuant
         to the terms of the plan of complete liquidation.

                  (b)      By their acceptance of Certificates, the Holders
thereof hereby agree to appoint the Trustee as their attorney in fact to: (i)
adopt such a plan of complete liquidation (and the Certificateholders hereby
appoint the Trustee as their attorney in fact to sign such plan) as appropriate
and (ii) to take such other action in connection therewith as may be reasonably
required to carry out such plan of complete liquidation all in accordance with
the terms hereof.

                            MISCELLANEOUS PROVISIONS

                  SECTION 11.01.    Amendment.

                  This Agreement may be amended from time to time by the
Depositor, the Master Servicer and the Trustee with the consent of the NIMS
Insurer and without the consent of the Certificateholders (i) to cure any
ambiguity, (ii) to correct or supplement any provisions herein which may be
defective or inconsistent with any other provisions herein, (iii) to amend the
provisions of Section 3.22(b) or (iv) 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 such action
shall not, as evidenced by either (a) an Opinion of Counsel delivered to the
Trustee or (b) written notice to the Depositor, the Master 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, adversely affect in any material
respect the interests of any Certificateholder. Neither an Opinion of Counsel
nor confirmation from the Rating Agencies will be required in connection with an
amendment to the provisions of Section 3.22(b). 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 or written notice
from the Rating Agencies shall be required to address the effect of any such
amendment on any such consenting Certificateholder.

                  This Agreement may also be amended from time to time by the
Depositor, the Master Servicer and the Trustee with the consent of the NIMS
Insurer and 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 Master
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 11.01, Certificates registered in the name of the Depositor or the
Master Servicer or any Affiliate thereof shall be entitled to Voting Rights with
respect to matters affecting such Certificates.

                  Notwithstanding any provision of this Agreement to the
contrary, the Trustee shall not consent to any amendment to this Agreement
unless it shall have first received an Opinion of Counsel, delivered by (and at
the expense of) the Person seeking such Amendment and satisfactory to the NIMS
Insurer, to the effect that such amendment will not result in the imposition of
a tax on any REMIC created hereunder constituting part of the Trust Fund
pursuant to the REMIC Provisions or cause any REMIC created hereunder
constituting part of the Trust to


                                      153
<PAGE>


fail to qualify as a REMIC at any time that any Certificates are outstanding and
that the amendment is being made in accordance with the terms hereof.

                  Promptly after the execution of any such amendment the Trustee
shall furnish, at the expense of the Person that requested the amendment if such
Person is the Master Servicer (but in no event at the expense of the Trustee),
otherwise at the expense of the Trust, a copy of such amendment and the Opinion
of Counsel referred to in the immediately preceding paragraph to the Master
Servicer, the NIMS Insurer and each Rating Agency.

                  It shall not be necessary for the consent of
Certificateholders under this Section 11.01 to approve the particular form of
any proposed amendment; instead 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 Trustee may, but shall not be obligated to, enter into any
amendment pursuant to this Section 11.01 that affects its rights, duties and
immunities under this Agreement or otherwise.

                  SECTION 11.02.    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 the counties or other comparable jurisdictions in which any or
all of the properties subject to the Mortgages are situated, and in any other
appropriate public recording office or elsewhere, such recordation to be
effected by the Master Servicer at the expense of the Trust, but only upon
direction of Certificateholders accompanied by an Opinion of Counsel to the
effect that such recordation materially and beneficially affects the interests
of the Certificateholders.

                  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
together constitute but one and the same instrument.

                  SECTION 11.03.    Limitation on Rights of Certificateholders.

                  The death or incapacity of any Certificateholder shall not (i)
operate to terminate this Agreement or the Trust, (ii) entitle such
Certificateholder's legal representatives or heirs to claim an accounting or to
take any action or proceeding in any court for a partition or winding up of the
Trust, or (iii) otherwise affect the rights, obligations and liabilities of the
parties hereto or any of them.

                  Except as expressly provided for herein, no Certificateholder
shall have any right to vote or in any manner otherwise control the operation
and management of the Trust, 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 person by reason of any action taken by the parties
to this Agreement pursuant to any provision hereof.


                                      154
<PAGE>


                  No Certificateholder shall have any right by virtue of any
provision 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 default
and of the continuance thereof, as hereinbefore provided, and unless also the
Holders of Certificates entitled to at least 25% of the Voting Rights shall have
made written request upon 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 15 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 is
understood and intended, and 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 of any
provision of this Agreement to affect, disturb or prejudice the rights of the
Holders of any other of such Certificates, or to obtain or seek to obtain
priority over or preference to any other such Holder, which priority or
preference is not otherwise provided for herein, or to enforce any right under
this Agreement, except in the manner herein provided and for the equal, ratable
and common benefit of all Certificateholders. For the protection and enforcement
of the provisions of this Section 11.03 each and every Certificateholder and the
Trustee shall be entitled to such relief as can be given either at law or in
equity.

                  SECTION 11.04.    Governing Law; Jurisdiction.

                  This Agreement shall be construed in accordance with the laws
of the State of New York, without regard to the conflicts of law provisions
thereof, and the obligations, rights and remedies of the parties hereunder shall
be determined in accordance with such laws. With respect to any claim arising
out of this Agreement, each party irrevocably submits to the exclusive
jurisdiction of the courts of the State of New York and the United States
District Court located in the Borough of Manhattan in The City of New York, and
each party irrevocably waives any objection which it may have at any time to the
laying of venue of any suit, action or proceeding arising out of or relating
hereto brought in any such courts, irrevocably waives any claim that any such
suit, action or proceeding brought in any such court has been brought in any
inconvenient forum and further irrevocably waives the right to object, with
respect to such claim, suit, action or proceeding brought in any such court,

such Distribution Date pursuant to the Agreement.

         Distributions on this Certificate shall be made by check or money order
mailed to the address of the person entitled thereto as it appears on the

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, but with the consent of the NIMS Insurer, if any.

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, but with the consent of the NIMS Insurer, if any.

rights, benefits, obligations and duties evidenced thereby, and the rights,
duties and immunities of the Trustee.

         Pursuant to the terms of the Agreement, a distribution will be made on

by the Depositor, the Master Servicer and the Trustee with the consent of the
NIMs Insurer, if any and of Holders of the requisite percentage of the

as specified in the Agreement. 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 therefor 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, but with the consent of the NIMS Insurer, if any.

         As provided in the Agreement and subject to certain limitations therein
set forth, the transfer of this Certificate is registrable in the Certificate
Register of the Trustee upon surrender of this Certificate for registration of
transfer at the office or agency maintained by the Trustee accompanied by a
written instrument of transfer in form satisfactory to the Trustee and the
Certificate Registrar duly executed by the holder hereof or such holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
of the same Class in authorized denominations and evidencing the same aggregate
Percentage Interest in the Trust will be issued to the designated transferee or
transferees.

         The Certificates are issuable only as registered Certificates without

exchange, but the Trustee may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

any, the Certificate Registrar, any Paying Agent and any agent of the Master
Servicer, the Depositor, the Trustee, the NIMs Insurer, if any, the Certificate
Registrar, any Paying Agent or the Trustee may treat the Person, including a
Depository, in whose name any Certificate is registered as the owner hereof for
all purposes, and none of the Master Servicer, the Trust, the Trustee nor any
agent of any of them shall be affected by notice to the contrary.

         On any Distribution Date following the date at which the remaining
aggregate Principal Balance of the Mortgage Loans is less than 10% of the sum of
the aggregate Principal Balance of the Initial Mortgage Loans as of the Cut-off
Date plus the Original Pre-Funded Amounts, the Master Servicer may purchase, in
whole, from the Trust the Mortgage Loans at a purchase price determined as
provided in the Agreement. In the event that no such optional termination
occurs, the obligations and responsibilities created by the Agreement will

Date on which the Certificate Principal Balances of the Regular Certificates
have been reduced to zero, (ii) the final payment or other liquidation of the
last Mortgage Loan in the Trust, (iii) the Distribution Date in February 2035.

         Principal in respect of this Certificate is distributable monthly as

servicer (the "Master Servicer"), and Wells Fargo Bank, N.A., a national banking
association, as Trustee (the "Trustee"). To the extent not defined herein, the

Class M-2 Certificate is issued under and is subject to the terms, provisions
and conditions of the Agreement, to which Agreement the Holder of this Class M-2
Certificate by virtue of the acceptance hereof assents and by which such Holder
is bound.

         Each Transferee of this Certificate will be deemed to have represented
by virtue of its purchase or holding of such Certificate (or interest therein)
that either (a) such Transferee is not a Plan or purchasing such Certificate
with Plan Assets, (b) it has acquired and is holding such Certificate in
reliance on the Prohibited Transaction Exemption (the "Exemption") set forth in
the Agreement and that it understands that there are certain conditions to the
availability of the Exemption including that such Certificate must be rated, at
the time of purchase, not lower than "BBB-" (or its equivalent) by a Rating
Agency or (c) the following conditions are satisfied: (i) such Transferee is an
insurance company, (ii) the source of funds used to purchase or hold such
Certificate (or interest therein) is an "insurance company general account" (as
defined in U.S. Department of Labor Prohibited Transaction Class Exemption
("PTCE") 95-60), and (iii) the conditions set forth in Sections I and III of
PTCE 95-60 have been satisfied.

         Reference is hereby made to the further provisions of this Class M-2
Certificate set forth on the reverse hereof, which further provisions shall for
all purposes have the same effect as if set forth at this place.

         This Certificate is one of a duly authorized issue of Certificates
designated as Option One Mortgage Loan Trust 2005-1, Asset-Backed Certificates,
Series 2005-1 (herein collectively called the "Certificates"), and representing
a beneficial ownership interest in the Trust created by the Agreement.

         The Certificateholder, by its acceptance of this Certificate, agrees
that it will look solely to the funds on deposit in the Distribution Account for
payment hereunder and that the Trustee is not liable to the Certificateholders
for any amount payable under this Certificate or the Agreement or, except as
expressly provided in the Agreement, subject to any liability under the
Agreement.

         This Certificate does not purport to summarize the Agreement and
reference is made to the Agreement for the interests, rights and limitations of
rights, benefits, obligations and duties evidenced thereby, and the rights,
duties and immunities of the Trustee.

         Pursuant to the terms of the Agreement, a distribution will be made on
the 25th day of each month or, if such 25th day is not a Business Day then the
first Business Day following such Distribution Date (the "Distribution Date"),
commencing on the first Distribution Date specified on the face hereof, to the
Person in whose name this Certificate is registered at the close of business on
the applicable 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 Holders of Certificates of the Class to which this Certificate belongs on
such Distribution Date pursuant to the Agreement.

         Distributions on this Certificate shall be made by check or money order
mailed to the address of the person entitled thereto as it appears on the
Certificate Register or by wire transfer or otherwise, as set forth in the
Agreement. The final distribution on each Certificate will be made in like
manner, but only upon presentment and surrender of such Certificate at the
office or agency of the Trustee specified in the notice to Certificateholders of
such final distribution.

         The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Trustee and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer and the Trustee with the consent of the
NIMs Insurer, if any and of Holders of the requisite percentage of the
Percentage Interests of each Class of Certificates affected by such amendment,
as specified in the Agreement. 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 therefor 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, but with the consent of the NIMS Insurer, if any.

         As provided in the Agreement and subject to certain limitations therein
set forth, the transfer of this Certificate is registrable in the Certificate
Register of the Trustee upon surrender of this Certificate for registration of
transfer at the office or agency maintained by the Trustee accompanied by a
written instrument of transfer in form satisfactory to the Trustee and the
Certificate Registrar duly executed by the holder hereof or such holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
of the same Class in authorized denominations and evidencing the same aggregate
Percentage Interest in the Trust will be issued to the designated transferee or
transferees.

         The Certificates are issuable only as registered Certificates without
coupons in denominations specified in the Agreement. As provided in the
Agreement and subject to certain limitations therein set forth, Certificates are
exchangeable for new Certificates of the same Class in authorized denominations
and 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, but the Trustee may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

         The Master Servicer, the Depositor, the Trustee, the NIMs Insurer, if
any, the Certificate Registrar, any Paying Agent and any agent of the Master
Servicer, the Depositor, the Trustee, the NIMs Insurer, if any, the Certificate
Registrar, any Paying Agent or the Trustee may treat the Person, including a
Depository, in whose name any Certificate is registered as the owner hereof for
all purposes, and none of the Master Servicer, the Trust, the Trustee nor any
agent of any of them shall be affected by notice to the contrary.

         On any Distribution Date following the date at which the remaining
aggregate Principal Balance of the Mortgage Loans is less than 10% of the sum of
the aggregate Principal Balance of the Initial Mortgage Loans as of the Cut-off
Date plus the Original Pre-Funded Amounts, the Master Servicer may purchase, in
whole, from the Trust the Mortgage Loans at a purchase price determined as
provided in the Agreement. In the event that no such optional termination
occurs, the obligations and responsibilities created by the Agreement will
terminate upon notice to the Trustee upon the earliest of (i) the Distribution
Date on which the Certificate Principal Balances of the Regular Certificates
have been reduced to zero, (ii) the final payment or other liquidation of the
last Mortgage Loan in the Trust, (iii) the Distribution Date in February 2035.

         Capitalized terms used herein that are defined in the Agreement shall
have the meanings ascribed to them in the Agreement, and nothing herein shall be
deemed inconsistent with that meaning.

designated as Option One Mortgage Loan Trust 2005-1, Asset-Backed Certificates,
Series 2005-1 (herein collectively called the "Certificates"), and representing

         The Certificateholder, by its acceptance of this Certificate, agrees
that it will look solely to the funds on deposit in the Distribution Account for
payment hereunder and that the Trustee is not liable to the Certificateholders
for any amount payable under this Certificate or the Agreement or, except as
expressly provided in the Agreement, subject to any liability under the
Agreement.

         This Certificate does not purport to summarize the Agreement and
reference is made to the Agreement for the interests, rights and limitations of
rights, benefits, obligations and duties evidenced thereby, and the rights,
duties and immunities of the Trustee.

         Pursuant to the terms of the Agreement, a distribution will be made on
the 25th day of each month or, if such 25th day is not a Business Day then the
first Business Day following such Distribution Date (the "Distribution Date"),
commencing on the first Distribution Date specified on the face hereof, to the
Person in whose name this Certificate is registered at the close of business on
the applicable 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 Holders of Certificates of the Class to which this Certificate belongs on
such Distribution Date pursuant to the Agreement.

         Distributions on this Certificate shall be made by check or money order
mailed to the address of the person entitled thereto as it appears on the
Certificate Register or by wire transfer or otherwise, as set forth in the
Agreement. The final distribution on each Certificate will be made in like
manner, but only upon presentment and surrender of such Certificate at the
office or agency of the Trustee specified in the notice to Certificateholders of
such final distribution.

         The Agreement permits, with certain exceptions therein provided, the

Trustee and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer and the Trustee with the consent of the
NIMs Insurer, if any and of Holders of the requisite percentage of the
Percentage Interests of each Class of Certificates affected by such amendment,
as specified in the Agreement. 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 therefor 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, but with the consent of the NIMS Insurer, if any.

         As provided in the Agreement and subject to certain limitations therein
set forth, the transfer of this Certificate is registrable in the Certificate
Register of the Trustee upon surrender of this Certificate for registration of
transfer at the office or agency maintained by the Trustee accompanied by a
written instrument of transfer in form satisfactory to the Trustee and the
Certificate Registrar duly executed by the holder hereof or such holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
of the same Class in authorized denominations and evidencing the same aggregate
Percentage Interest in the Trust will be issued to the designated transferee or
transferees.

         The Certificates are issuable only as registered Certificates without
coupons in denominations specified in the Agreement. As provided in the
Agreement and subject to certain limitations therein set forth, Certificates are
exchangeable for new Certificates of the same Class in authorized denominations
and 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, but the Trustee may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

         The Master Servicer, the Depositor, the Trustee, the NIMs Insurer, if
any, the Certificate Registrar, any Paying Agent and any agent of the Master
Servicer, the Depositor, the Trustee, the NIMs Insurer, if any, the Certificate
Registrar, any Paying Agent or the Trustee may treat the Person, including a
Depository, in whose name any Certificate is registered as the owner hereof for
all purposes, and none of the Master Servicer, the Trust, the Trustee nor any
agent of any of them shall be affected by notice to the contrary.

         On any Distribution Date following the date at which the remaining
aggregate Principal Balance of the Mortgage Loans is less than 10% of the sum of
the aggregate Principal Balance of the Initial Mortgage Loans as of the Cut-off
Date plus the Original Pre-Funded Amounts, the Master Servicer may purchase, in
whole, from the Trust the Mortgage Loans at a purchase price determined as
provided in the Agreement. In the event that no such optional termination
occurs, the obligations and responsibilities created by the Agreement will

Date on which the Certificate Principal Balances of the Regular Certificates
have been reduced to zero, (ii) the final payment or other liquidation of the
last Mortgage Loan in the Trust, (iii) the Distribution Date in February 2035.

have the meanings ascribed to them in the Agreement, and nothing herein shall be
deemed inconsistent with that meaning.

and conditions of the Agreement, to which Agreement the Holder of this Class M-4
Certificate by virtue of the acceptance hereof assents and by which such Holder
is bound.

         Each Transferee of this Certificate will be deemed to have represented
by virtue of its purchase or holding of such Certificate (or interest therein)
that either (a) such Transferee is not a Plan or purchasing such Certificate
with Plan Assets, (b) it has acquired and is holding such Certificate in
reliance on the Prohibited Transaction Exemption (the "Exemption") set forth in

availability of the Exemption including that such Certificate must be rated, at
the time of purchase, not lower than "BBB-" (or its equivalent) by a Rating
Agency or (c) the following conditions are satisfied: (i) such Transferee is an
insurance company, (ii) the source of funds used to purchase or hold such
Certificate (or interest therein) is an "insurance company general account" (as
defined in U.S. Department of Labor Prohibited Transaction Class Exemption
("PTCE") 95-60), and (iii) the conditions set forth in Sections I and III of
PTCE 95-60 have been satisfied.

         Reference is hereby made to the further provisions of this Class M-4
Certificate set forth on the reverse hereof, which further provisions shall for
all purposes have the same effect as if set forth at this place.

            OPTION ONE MORTGAGE ACCEPTANCE CORPORATION, as Depositor

         Principal in respect of this Certificate is distributable monthly as
set forth herein. Accordingly, the Certificate Principal Balance of this Class
M-5 Certificate at any time may be less than the Initial Certificate Principal
Balance set forth on the face hereof, as described herein. This Class M-5
Certificate does not evidence an obligation of, or an interest in, and is not

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

Certificate Principal Balance) in certain monthly distributions with respect to
a Trust consisting primarily of the Mortgage Loans deposited by Option One
Mortgage Acceptance Corporation (the "Depositor"). The Trust was created
pursuant to a Pooling and Servicing Agreement dated as of January 1, 2005 (the
"Agreement") among the Depositor, Option One Mortgage Corporation, as master
servicer (the "Master Servicer"), and Wells Fargo Bank, N.A., a national banking
association, as Trustee (the "Trustee"). To the extent not defined herein, the
capitalized terms used herein have the meanings assigned in the Agreement. This
Class M-5 Certificate is issued under and is subject to the terms, provisions
and conditions of the Agreement, to which Agreement the Holder of this Class M-5
Certificate by virtue of the acceptance hereof assents and by which such Holder
is bound.

         Each Transferee of this Certificate will be deemed to have represented
by virtue of its purchase or holding of such Certificate (or interest therein)
that either (a) such Transferee is not a Plan or purchasing such Certificate
with Plan Assets, (b) it has acquired and is holding such Certificate in
reliance on the Prohibited Transaction Exemption (the "Exemption") set forth in
the Agreement and that it understands that there are certain conditions to the
availability of the Exemption including that such Certificate must be rated, at
the time of purchase, not lower than "BBB-" (or its equivalent) by a Rating
Agency or (c) the following conditions are satisfied: (i) such Transferee is an
insurance company, (ii) the source of funds used to purchase or hold such
Certificate (or interest therein) is an "insurance company general account" (as
defined in U.S. Department of Labor Prohibited Transaction Class Exemption
("PTCE") 95-60), and (iii) the conditions set forth in Sections I and III of
PTCE 95-60 have been satisfied.

         Reference is hereby made to the further provisions of this Class M-5
Certificate set forth on the reverse hereof, which further provisions shall for
all purposes have the same effect as if set forth at this place.

         This Certificate is one of a duly authorized issue of Certificates
designated as Option One Mortgage Loan Trust 2005-1, Asset-Backed Certificates,
Series 2005-1 (herein collectively called the "Certificates"), and representing
a beneficial ownership interest in the Trust created by the Agreement.

         The Certificateholder, by its acceptance of this Certificate, agrees
that it will look solely to the funds on deposit in the Distribution Account for
payment hereunder and that the Trustee is not liable to the Certificateholders
for any amount payable under this Certificate or the Agreement or, except as
expressly provided in the Agreement, subject to any liability under the
Agreement.

         This Certificate does not purport to summarize the Agreement and
reference is made to the Agreement for the interests, rights and limitations of
rights, benefits, obligations and duties evidenced thereby, and the rights,
duties and immunities of the Trustee.

         Pursuant to the terms of the Agreement, a distribution will be made on
the 25th day of each month or, if such 25th day is not a Business Day then the
first Business Day following such Distribution Date (the "Distribution Date"),
commencing on the first Distribution Date specified on the face hereof, to the
Person in whose name this Certificate is registered at the close of business on
the applicable Record Date in an amount equal to the product of the Percentage

such Distribution Date pursuant to the Agreement.

         Distributions on this Certificate shall be made by check or money order
mailed to the address of the person entitled thereto as it appears on the

amendment thereof and the modification of the rights and obligations of the
Trustee and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer and the Trustee with the consent of the
NIMs Insurer, if any and of Holders of the requisite percentage of the
Percentage Interests of each Class of Certificates affected by such amendment,
as specified in the Agreement. 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 therefor 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, but with the consent of the NIMS Insurer, if any.

         As provided in the Agreement and subject to certain limitations therein
set forth, the transfer of this Certificate is registrable in the Certificate
Register of the Trustee upon surrender of this Certificate for registration of
transfer at the office or agency maintained by the Trustee accompanied by a
written instrument of transfer in form satisfactory to the Trustee and the
Certificate Registrar duly executed by the holder hereof or such holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
of the same Class in authorized denominations and evidencing the same aggregate
Percentage Interest in the Trust will be issued to the designated transferee or
transferees.

         The Certificates are issuable only as registered Certificates without
coupons in denominations specified in the Agreement. As provided in the
Agreement and subject to certain limitations therein set forth, Certificates are
exchangeable for new Certificates of the same Class in authorized denominations
and 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, but the Trustee may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

         The Master Servicer, the Depositor, the Trustee, the NIMs Insurer, if
any, the Certificate Registrar, any Paying Agent and any agent of the Master
Servicer, the Depositor, the Trustee, the NIMs Insurer, if any, the Certificate
Registrar, any Paying Agent or the Trustee may treat the Person, including a
Depository, in whose name any Certificate is registered as the owner hereof for
all purposes, and none of the Master Servicer, the Trust, the Trustee nor any
agent of any of them shall be affected by notice to the contrary.

         On any Distribution Date following the date at which the remaining
aggregate Principal Balance of the Mortgage Loans is less than 10% of the sum of
the aggregate Principal Balance of the Initial Mortgage Loans as of the Cut-off
Date plus the Original Pre-Funded Amounts, the Master Servicer may purchase, in
whole, from the Trust the Mortgage Loans at a purchase price determined as
provided in the Agreement. In the event that no such optional termination
occurs, the obligations and responsibilities created by the Agreement will
terminate upon notice to the Trustee upon the earliest of (i) the Distribution
Date on which the Certificate Principal Balances of the Regular Certificates
have been reduced to zero, (ii) the final payment or other liquidation of the
last Mortgage Loan in the Trust, (iii) the Distribution Date in February 2035.

         Capitalized terms used herein that are defined in the Agreement shall
have the meanings ascribed to them in the Agreement, and nothing herein shall be
deemed inconsistent with that meaning.

and conditions of the Agreement, to which Agreement the Holder of this Class M-7
Certificate by virtue of the acceptance hereof assents and by which such Holder
is bound.

by virtue of its purchase or holding of such Certificate (or interest therein)
that either (a) such Transferee is not a Plan or purchasing such Certificate
with Plan Assets, (b) it has acquired and is holding such Certificate in
reliance on the Prohibited Transaction Exemption (the "Exemption") set forth in

availability of the Exemption including that such Certificate must be rated, at
the time of purchase, not lower than "BBB-" (or its equivalent) by a Rating
Agency or (c) the following conditions are satisfied: (i) such Transferee is an
insurance company, (ii) the source of funds used to purchase or hold such
Certificate (or interest therein) is an "insurance company general account" (as
defined in U.S. Department of Labor Prohibited Transaction Class Exemption
("PTCE") 95-60), and (iii) the conditions set forth in Sections I and III of
PTCE 95-60 have been satisfied.

         Reference is hereby made to the further provisions of this Class M-7
Certificate set forth on the reverse hereof, which further provisions shall for

with Plan Assets, (b) it has acquired and is holding such Certificate in
reliance on the Prohibited Transaction Exemption (the "Exemption") set forth in

Agency or (c) the following conditions are satisfied: (i) such Transferee is an
insurance company, (ii) the source of funds used to purchase or hold such

("PTCE") 95-60), and (iii) the conditions set forth in Sections I and III of
PTCE 95-60 have been satisfied.

                           Asset-Backed Certificates,
                                  Series 2005-1

         This Certificate is one of a duly authorized issue of Certificates
designated as Option One Mortgage Loan Trust 2005-1, Asset-Backed Certificates,
Series 2005-1 (herein collectively called the "Certificates"), and representing
a beneficial ownership interest in the Trust created by the Agreement.

         The Certificateholder, by its acceptance of this Certificate, agrees
that it will look solely to the funds on deposit in the Distribution Account for
payment hereunder and that the Trustee is not liable to the Certificateholders
for any amount payable under this Certificate or the Agreement or, except as
expressly provided in the Agreement, subject to any liability under the
Agreement.

         This Certificate does not purport to summarize the Agreement and
reference is made to the Agreement for the interests, rights and limitations of
rights, benefits, obligations and duties evidenced thereby, and the rights,
duties and immunities of the Trustee.

         Pursuant to the terms of the Agreement, a distribution will be made on
the 25th day of each month or, if such 25th day is not a Business Day then the
first Business Day following such Distribution Date (the "Distribution Date"),
commencing on the first Distribution Date specified on the face hereof, to the
Person in whose name this Certificate is registered at the close of business on
the applicable 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 Holders of Certificates of the Class to which this Certificate belongs on
such Distribution Date pursuant to the Agreement.

         Distributions on this Certificate shall be made by check or money order
mailed to the address of the person entitled thereto as it appears on the
Certificate Register or by wire transfer or otherwise, as set forth in the
Agreement. The final distribution on each Certificate will be made in like
manner, but only upon presentment and surrender of such Certificate at the
office or agency of the Trustee specified in the notice to Certificateholders of
such final distribution.

         The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Trustee and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer and the Trustee with the consent of the
NIMs Insurer, if any and of Holders of the requisite percentage of the
Percentage Interests of each Class of Certificates affected by such amendment,
as specified in the Agreement. 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 therefor 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, but with the consent of the NIMS Insurer, if any.

         As provided in the Agreement and subject to certain limitations therein
set forth, the transfer of this Certificate is registrable in the Certificate
Register of the Trustee upon surrender of this Certificate for registration of
transfer at the office or agency maintained by the Trustee accompanied by a
written instrument of transfer in form satisfactory to the Trustee and the
Certificate Registrar duly executed by the holder hereof or such holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
of the same Class in authorized denominations and evidencing the same aggregate
Percentage Interest in the Trust will be issued to the designated transferee or
transferees.

         The Certificates are issuable only as registered Certificates without
coupons in denominations specified in the Agreement. As provided in the
Agreement and subject to certain limitations therein set forth, Certificates are
exchangeable for new Certificates of the same Class in authorized denominations
and 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, but the Trustee may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

         The Master Servicer, the Depositor, the Trustee, the NIMs Insurer, if
any, the Certificate Registrar, any Paying Agent and any agent of the Master
Servicer, the Depositor, the Trustee, the NIMs Insurer, if any, the Certificate
Registrar, any Paying Agent or the Trustee may treat the Person, including a
Depository, in whose name any Certificate is registered as the owner hereof for
all purposes, and none of the Master Servicer, the Trust, the Trustee nor any
agent of any of them shall be affected by notice to the contrary.

         On any Distribution Date following the date at which the remaining
aggregate Principal Balance of the Mortgage Loans is less than 10% of the sum of
the aggregate Principal Balance of the Initial Mortgage Loans as of the Cut-off
Date plus the Original Pre-Funded Amounts, the Master Servicer may purchase, in
whole, from the Trust the Mortgage Loans at a purchase price determined as
provided in the Agreement. In the event that no such optional termination
occurs, the obligations and responsibilities created by the Agreement will
terminate upon notice to the Trustee upon the earliest of (i) the Distribution
Date on which the Certificate Principal Balances of the Regular Certificates
have been reduced to zero, (ii) the final payment or other liquidation of the
last Mortgage Loan in the Trust, (iii) the Distribution Date in February 2035.

         Capitalized terms used herein that are defined in the Agreement shall
have the meanings ascribed to them in the Agreement, and nothing herein shall be
deemed inconsistent with that meaning.

for any amount payable under this Certificate or the Agreement or, except as

         This Certificate does not purport to summarize the Agreement and
reference is made to the Agreement for the interests, rights and limitations of
rights, benefits, obligations and duties evidenced thereby, and the rights,
duties and immunities of the Trustee.

         Pursuant to the terms of the Agreement, a distribution will be made on
the 25th day of each month or, if such 25th day is not a Business Day then the
first Business Day following such Distribution Date (the "Distribution Date"),

Person in whose name this Certificate is registered at the close of business on
the applicable Record Date in an amount equal to the product of the Percentage

such Distribution Date pursuant to the Agreement.

         Distributions on this Certificate shall be made by check or money order

         The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Trustee and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer and the Trustee with the consent of the
NIMs Insurer, if any and of Holders of the requisite percentage of the
Percentage Interests of each Class of Certificates affected by such amendment,
as specified in the Agreement. 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 therefor 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, but with the consent of the NIMS Insurer, if any.

         As provided in the Agreement and subject to certain limitations therein
set forth, the transfer of this Certificate is registrable in the Certificate
Register of the Trustee upon surrender of this Certificate for registration of
transfer at the office or agency maintained by the Trustee accompanied by a
written instrument of transfer in form satisfactory to the Trustee and the
Certificate Registrar duly executed by the holder hereof or such holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
of the same Class in authorized denominations and evidencing the same aggregate
Percentage Interest in the Trust will be issued to the designated transferee or
transferees.

         The Certificates are issuable only as registered Certificates without
coupons in denominations specified in the Agreement. As provided in the
Agreement and subject to certain limitations therein set forth, Certificates are
exchangeable for new Certificates of the same Class in authorized denominations
and 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, but the Trustee may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

         The Master Servicer, the Depositor, the Trustee, the NIMs Insurer, if
any, the Certificate Registrar, any Paying Agent and any agent of the Master
Servicer, the Depositor, the Trustee, the NIMs Insurer, if any, the Certificate
Registrar, any Paying Agent or the Trustee may treat the Person, including a
Depository, in whose name any Certificate is registered as the owner hereof for
all purposes, and none of the Master Servicer, the Trust, the Trustee nor any
agent of any of them shall be affected by notice to the contrary.

         On any Distribution Date following the date at which the remaining
aggregate Principal Balance of the Mortgage Loans is less than 10% of the sum of
the aggregate Principal Balance of the Initial Mortgage Loans as of the Cut-off
Date plus the Original Pre-Funded Amounts, the Master Servicer may purchase, in
whole, from the Trust the Mortgage Loans at a purchase price determined as
provided in the Agreement. In the event that no such optional termination
occurs, the obligations and responsibilities created by the Agreement will
terminate upon notice to the Trustee upon the earliest of (i) the Distribution
Date on which the Certificate Principal Balances of the Regular Certificates
have been reduced to zero, (ii) the final payment or other liquidation of the
last Mortgage Loan in the Trust, (iii) the Distribution Date in February 2035.

have the meanings ascribed to them in the Agreement, and nothing herein shall be

         the Certificates of the above-referenced Class with respect to the

         mortgage loans (the "Mortgage Loans")

            OPTION ONE MORTGAGE ACCEPTANCE CORPORATION, as Depositor

         Principal in respect of this Certificate is distributable monthly as
set forth herein. Accordingly, the Certificate Principal Balance of this Class C
Certificate at any time may be less than the Initial Certificate Principal
Balance set forth on the face hereof, as described herein. This Class C
Certificate does not evidence an obligation of, or an interest in, and is not
guaranteed by the Depositor, the Master Servicer, or the Trustee referred to
below or any of their respective affiliates.

         This certifies that Option One Mortgage Corporation is the registered
owner of the Percentage Interest evidenced by this Class C Certificate (obtained
by dividing the Denomination of this Class C Certificate by the Original Class
Certificate Principal Balance) in certain distributions with respect to a Trust
consisting primarily of the Mortgage Loans deposited by Option One Mortgage
Acceptance Corporation (the "Depositor"). The Trust was created pursuant to a
Pooling and Servicing Agreement dated as of January 1, 2005 (the "Agreement")
among the Depositor, Option One Mortgage Corporation, as master servicer (the
"Master Servicer"), and Wells Fargo Bank, N.A., a national banking association,
as Trustee (the "Trustee"). To the extent not defined herein, the capitalized
terms used herein have the meanings assigned in the Agreement. This Class C
Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Class C
Certificate by virtue of the acceptance hereof assents and by which such Holder
is bound.

         No transfer of a Certificate of this Class shall be made unless such
transfer is made pursuant to an effective registration statement under the Act
and any applicable state securities laws or is exempt from the registration
requirements under said Act and such laws. In the event that a transfer is to be
made in reliance upon an exemption from the Act and such laws, in order to
assure compliance with the Act and such laws, the Certificateholder desiring to
effect such transfer and such Certificateholder's prospective transferee shall
each certify to the Trustee and the Depositor in writing the facts surrounding
the transfer. In the event that such a transfer is not to be made pursuant to
Rule 144A of the Act, there shall be delivered to the Trustee and the Depositor
an Opinion of Counsel that such transfer may be made pursuant to an exemption
from the Act, which Opinion of Counsel shall not be obtained at the expense of
the Trustee or the Depositor; or there shall be delivered to the Trustee and the
Depositor a transferor certificate by the transferor and an investment letter
shall be executed by the transferee. The Holder hereof 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.

         This Certificate is one of a duly authorized issue of Certificates
designated as Option One Mortgage Loan Trust 2005-1, Asset-Backed Certificates,
Series 2005-1 (herein collectively called the "Certificates"), and representing
a beneficial ownership interest in the Trust created by the Agreement.

         The Certificateholder, by its acceptance of this Certificate, agrees
that it will look solely to the funds on deposit in the Distribution Account for
payment hereunder and that the Trustee is not liable to the Certificateholders
for any amount payable under this Certificate or the Agreement or, except as
expressly provided in the Agreement, subject to any liability under the
Agreement.

         This Certificate does not purport to summarize the Agreement and
reference is made to the Agreement for the interests, rights and limitations of
rights, benefits, obligations and duties evidenced thereby, and the rights,
duties and immunities of the Trustee.

         Pursuant to the terms of the Agreement, a distribution will be made on
the 25th day of each month or, if such 25th day is not a Business Day then the
first Business Day following such Distribution Date (the "Distribution Date"),
commencing on the first Distribution Date specified on the face hereof, to the
Person in whose name this Certificate is registered at the close of business on
the applicable 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 Holders of Certificates of the Class to which this Certificate belongs on
such Distribution Date pursuant to the Agreement.

         Distributions on this Certificate shall be made by check or money order
mailed to the address of the person entitled thereto as it appears on the
Certificate Register or by wire transfer or otherwise, as set forth in the
Agreement. The final distribution on each Certificate will be made in like
manner, but only upon presentment and surrender of such Certificate at the
office or agency of the Trustee specified in the notice to Certificateholders of
such final distribution.

         The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Trustee and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer and the Trustee with the consent of the
NIMs Insurer, if any and of Holders of the requisite percentage of the
Percentage Interests of each Class of Certificates affected by such amendment,
as specified in the Agreement. 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 therefor 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, but with the consent of the NIMS Insurer, if any.

         As provided in the Agreement and subject to certain limitations therein
set forth, the transfer of this Certificate is registrable in the Certificate
Register of the Trustee upon surrender of this Certificate for registration of
transfer at the office or agency maintained by the Trustee accompanied by a
written instrument of transfer in form satisfactory to the Trustee and the
Certificate Registrar duly executed by the holder hereof or such holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
of the same Class in authorized denominations and evidencing the same aggregate
Percentage Interest in the Trust will be issued to the designated transferee or
transferees.

         The Certificates are issuable only as registered Certificates without
coupons in denominations specified in the Agreement. As provided in the
Agreement and subject to certain limitations therein set forth, Certificates are
exchangeable for new Certificates of the same Class in authorized denominations
and 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, but the Trustee may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

         The Master Servicer, the Depositor, the Trustee, the NIMs Insurer, if
any, the Certificate Registrar, any Paying Agent and any agent of the Master
Servicer, the Depositor, the Trustee, the NIMs Insurer, if any, the Certificate
Registrar, any Paying Agent or the Trustee may treat the Person, including a
Depository, in whose name any Certificate is registered as the owner hereof for
all purposes, and none of the Master Servicer, the Trust, the Trustee nor any
agent of any of them shall be affected by notice to the contrary.

         On any Distribution Date following the date at which the remaining
aggregate Principal Balance of the Mortgage Loans is less than 10% of the sum of
the aggregate Principal Balance of the Initial Mortgage Loans as of the Cut-off
Date plus the Original Pre-Funded Amounts, the Master Servicer may purchase, in
whole, from the Trust the Mortgage Loans at a purchase price determined as
provided in the Agreement. In the event that no such optional termination
occurs, the obligations and responsibilities created by the Agreement will
terminate upon notice to the Trustee upon the earliest of (i) the Distribution
Date on which the Certificate Principal Balances of the Regular Certificates
have been reduced to zero, (ii) the final payment or other liquidation of the
last Mortgage Loan in the Trust, (iii) the Distribution Date in February 2035.

         Capitalized terms used herein that are defined in the Agreement shall
have the meanings ascribed to them in the Agreement, and nothing herein shall be
deemed inconsistent with that meaning.

         The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Trustee and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer and the Trustee with the consent of the
NIMs Insurer, if any and of Holders of the requisite percentage of the
Percentage Interests of each Class of Certificates affected by such amendment,
as specified in the Agreement. 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 therefor 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, but with the consent of the NIMS Insurer, if any.

transfer at the office or agency maintained by the Trustee accompanied by a
written instrument of transfer in form satisfactory to the Trustee and the

Depository, in whose name any Certificate is registered as the owner hereof for
all purposes, and none of the Master Servicer, the Trust, the Trustee nor any
agent of any of them shall be affected by notice to the contrary.

         On any Distribution Date following the date at which the remaining
aggregate Principal Balance of the Mortgage Loans is less than 10% of the sum of
the aggregate Principal Balance of the Initial Mortgage Loans as of the Cut-off
Date plus the Original Pre-Funded Amounts, the Master Servicer may purchase, in
whole, from the Trust the Mortgage Loans at a purchase price determined as
provided in the Agreement. In the event that no such optional termination

Date on which the Certificate Principal Balances of the Regular Certificates
have been reduced to zero, (ii) the final payment or other liquidation of the
last Mortgage Loan in the Trust, (iii) the Distribution Date in February 2035.

         evidencing the Percentage Interest in the distributions allocable to
         the Certificates of the above-referenced Class with respect to the
         Trust consisting of first and second lien, adjustable and fixed rate
         mortgage loans (the "Mortgage Loans")

            OPTION ONE MORTGAGE ACCEPTANCE CORPORATION, as Depositor

         This Certificate does not evidence an obligation of, or an interest in,
and is not guaranteed by the Depositor, the Master Servicer or the Trustee
referred to below or any of their respective affiliates.

         This certifies that Option One Mortgage Corporation is the registered
owner of the Percentage Interest evidenced by this Certificate specified above
in the interest represented by all Certificates of the Class to which this
Certificate belongs in a Trust consisting primarily of the Mortgage Loans
deposited by Option One Mortgage Acceptance Corporation (the "Depositor"). The
Trust was created pursuant to a Pooling and Servicing Agreement dated as of
January 1, 2005 (the "Agreement") among the Depositor, Option One Mortgage
Corporation, as master servicer (the "Master Servicer") and Wells Fargo Bank,
N.A., a national banking association, as trustee (the "Trustee"). 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.

         This Certificate does not have a principal balance or pass-through rate
and will be entitled to distributions only to the extent set forth in the
Agreement. In addition, any distribution of the proceeds of any remaining assets
of the Trust will be made only upon presentment and surrender of this
Certificate at the Corporate Trust Office or the office or agency maintained by
the Trustee in Minneapolis, Minnesota.

         No transfer of a Certificate of this Class shall be made unless such
transfer is made pursuant to an effective registration statement under the Act
and any applicable state securities laws or is exempt from the registration
requirements under said Act and such laws. In the event that a transfer is to be
made in reliance upon an exemption from the Act and such laws, in order to
assure compliance with the Act and such laws, the Certificateholder desiring to
effect such transfer and such Certificateholder's prospective transferee shall
each certify to the Trustee and the Depositor in writing the facts surrounding
the transfer. In the event that such a transfer is not to be made pursuant to
Rule 144A of the Act, there shall be delivered to the Trustee and the Depositor
an Opinion of Counsel that such transfer may be made pursuant to an exemption
from the Act, which Opinion of Counsel shall not be obtained at the expense of
the Trustee or the Depositor; or there shall be delivered to the Trustee and the
Depositor a transferor certificate by the transferor and an investment letter
shall be executed by the transferee. The Holder hereof desiring to effect such
transfer shall, and does hereby agree to, indemnify the Trustee and the


                                     A-17-2
<PAGE>

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.

         No transfer of this Certificate to a Plan subject to ERISA or Section
4975 of the Code, any Person acting, directly or indirectly, on behalf of any
such Plan or any person using Plan Assets to acquire this Certificate shall be
made except in accordance with Section 5.02(d) of the Agreement.

         Each Holder of this Certificate will be deemed to have agreed to be
bound by the restrictions of the Agreement, including but not limited to the
restrictions that (i) each person holding or acquiring any Ownership Interest in
this Certificate must be a Permitted Transferee, (ii) no Ownership Interest in
this Certificate may be transferred without delivery to the Trustee of (a) a
transfer affidavit of the proposed transferee and (b) a transfer certificate of
the transferor, each of such documents to be in the form described in the
Agreement, (iii) each person holding or acquiring any Ownership Interest in this
Certificate must agree to require a transfer affidavit and to deliver a transfer
certificate to the Trustee as required pursuant to the Agreement, (iv) each
person holding or acquiring an Ownership Interest in this Certificate must agree
not to transfer an Ownership Interest in this Certificate if it has actual
knowledge that the proposed transferee is not a Permitted Transferee and (v) any
attempted or purported transfer of any Ownership Interest in this Certificate in
violation of such restrictions will be absolutely null and void and will vest no
rights in the purported transferee. Pursuant to the Agreement, the Trustee will
provide the Internal Revenue Service and any pertinent persons with the
information needed to compute the tax imposed under the applicable tax laws on
transfers of residual interests to disqualified organizations, if any person
other than a Permitted Transferee acquires an Ownership Interest on a Class R
Certificate in violation of the restrictions mentioned above.

         Reference is hereby made to the further provisions of this Class R
Certificate set forth on the reverse hereof, which further provisions shall for
all purposes have the same effect as if set forth at this place.

         This Certificate shall not be entitled to any benefit under the
Agreement or be valid for any purpose unless manually countersigned by an
authorized signatory of the Trustee.

         evidencing the Percentage Interest in the distributions allocable to
         the Certificates of the above-referenced Class with respect to the
         Trust consisting of first and second lien, adjustable and fixed rate
         mortgage loans (the "Mortgage Loans")

            OPTION ONE MORTGAGE ACCEPTANCE CORPORATION, as Depositor

         This Certificate does not evidence an obligation of, or an interest in,
and is not guaranteed by the Depositor, the Master Servicer or the Trustee
referred to below or any of their respective affiliates.

         This certifies that Option One Mortgage Corporation is the registered
owner of the Percentage Interest evidenced by this Certificate specified above
in the interest represented by all Certificates of the Class to which this
Certificate belongs in a Trust consisting primarily of the Mortgage Loans
deposited by Option One Mortgage Acceptance Corporation (the "Depositor"). The
Trust was created pursuant to a Pooling and Servicing Agreement dated as of
January 1, 2005 (the "Agreement") among the Depositor, Option One Mortgage
Corporation, as master servicer (the "Master Servicer") and Wells Fargo Bank,
N.A., a national banking association, as trustee (the "Trustee"). 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.

         This Certificate does not have a principal balance or pass-through rate
and will be entitled to distributions only to the extent set forth in the
Agreement. In addition, any distribution of the proceeds of any remaining assets
of the Trust will be made only upon presentment and surrender of this
Certificate at the Corporate Trust Office or the office or agency maintained by
the Trustee in Minneapolis, Minnesota.

         No transfer of a Certificate of this Class shall be made unless such
transfer is made pursuant to an effective registration statement under the Act
and any applicable state securities laws or is exempt from the registration
requirements under said Act and such laws. In the event that a transfer is to be
made in reliance upon an exemption from the Act and such laws, in order to
assure compliance with the Act and such laws, the Certificateholder desiring to
effect such transfer and such Certificateholder's prospective transferee shall
each certify to the Trustee and the Depositor in writing the facts surrounding
the transfer. In the event that such a transfer is not to be made pursuant to
Rule 144A of the Act, there shall be delivered to the Trustee and the Depositor
an Opinion of Counsel that such transfer may be made pursuant to an exemption
from the Act, which Opinion of Counsel shall not be obtained at the expense of
the Trustee or the Depositor; or there shall be delivered to the Trustee and the
Depositor a transferor certificate by the transferor and an investment letter
shall be executed by the transferee. The Holder hereof desiring to effect such
transfer shall, and does hereby agree to, indemnify the Trustee and the

                                     A-18-2
<PAGE>

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.

         No transfer of this Certificate to a Plan subject to ERISA or Section
4975 of the Code, any Person acting, directly or indirectly, on behalf of any
such Plan or any person using Plan Assets to acquire this Certificate shall be
made except in accordance with Section 5.02(d) of the Agreement.

         Each Holder of this Certificate will be deemed to have agreed to be
bound by the restrictions of the Agreement, including but not limited to the
restrictions that (i) each person holding or acquiring any Ownership Interest in
this Certificate must be a Permitted Transferee, (ii) no Ownership Interest in
this Certificate may be transferred without delivery to the Trustee of (a) a
transfer affidavit of the proposed transferee and (b) a transfer certificate of
the transferor, each of such documents to be in the form described in the
Agreement, (iii) each person holding or acquiring any Ownership Interest in this
Certificate must agree to require a transfer affidavit and to deliver a transfer
certificate to the Trustee as required pursuant to the Agreement, (iv) each
person holding or acquiring an Ownership Interest in this Certificate must agree
not to transfer an Ownership Interest in this Certificate if it has actual
knowledge that the proposed transferee is not a Permitted Transferee and (v) any
attempted or purported transfer of any Ownership Interest in this Certificate in
violation of such restrictions will be absolutely null and void and will vest no
rights in the purported transferee. Pursuant to the Agreement, the Trustee will
provide the Internal Revenue Service and any pertinent persons with the
information needed to compute the tax imposed under the applicable tax laws on
transfers of residual interests to disqualified organizations, if any person
other than a Permitted Transferee acquires an Ownership Interest on a Class R-X
Certificate in violation of the restrictions mentioned above.

         Reference is hereby made to the further provisions of this Class R-X
Certificate set forth on the reverse hereof, which further provisions shall for
all purposes have the same effect as if set forth at this place.

         This Certificate shall not be entitled to any benefit under the
Agreement or be valid for any purpose unless manually countersigned by an
authorized signatory of the Trustee.

                           Asset-Backed Certificates,
                                  Series 2005-1

         This Certificate is one of a duly authorized issue of Certificates
designated as Option One Mortgage Loan Trust 2005-1, Asset-Backed Certificates,
Series 2005-1 (herein collectively called the "Certificates"), and representing
a beneficial ownership interest in the Trust created by the Agreement.

         The Certificateholder, by its acceptance of this Certificate, agrees
that it will look solely to the funds on deposit in the Distribution Account for
payment hereunder and that the Trustee is not liable to the Certificateholders
for any amount payable under this Certificate or the Agreement or, except as
expressly provided in the Agreement, subject to any liability under the
Agreement.

         This Certificate does not purport to summarize the Agreement and
reference is made to the Agreement for the interests, rights and limitations of
rights, benefits, obligations and duties evidenced thereby, and the rights,
duties and immunities of the Trustee.

         Pursuant to the terms of the Agreement, a distribution will be made on
the 25th day of each month or, if such 25th day is not a Business Day then the
first Business Day following such Distribution Date (the "Distribution Date"),
commencing on the first Distribution Date specified on the face hereof, to the
Person in whose name this Certificate is registered at the close of business on
the applicable 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 Holders of Certificates of the Class to which this Certificate belongs on
such Distribution Date pursuant to the Agreement.

         Distributions on this Certificate shall be made by check or money order
mailed to the address of the person entitled thereto as it appears on the
Certificate Register or by wire transfer or otherwise, as set forth in the
Agreement. The final distribution on each Certificate will be made in like
manner, but only upon presentment and surrender of such Certificate at the
office or agency of the Trustee specified in the notice to Certificateholders of
such final distribution.

         The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Trustee and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer and the Trustee with the consent of the
NIMs Insurer, if any and of Holders of the requisite percentage of the
Percentage Interests of each Class of Certificates affected by such amendment,
as specified in the Agreement. 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 therefor 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, but with the consent of the NIMS Insurer, if any.

         As provided in the Agreement and subject to certain limitations therein
set forth, the transfer of this Certificate is registrable in the Certificate
Register of the Trustee upon surrender of this Certificate for registration of
transfer at the office or agency maintained by the Trustee accompanied by a
written instrument of transfer in form satisfactory to the Trustee and the
Certificate Registrar duly executed by the holder hereof or such holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
of the same Class in authorized denominations and evidencing the same aggregate
Percentage Interest in the Trust will be issued to the designated transferee or
transferees.

         The Certificates are issuable only as registered Certificates without
coupons in denominations specified in the Agreement. As provided in the
Agreement and subject to certain limitations therein set forth, Certificates are
exchangeable for new Certificates of the same Class in authorized denominations
and 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, but the Trustee may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

         The Master Servicer, the Depositor, the Trustee, the NIMs Insurer, if
any, the Certificate Registrar, any Paying Agent and any agent of the Master
Servicer, the Depositor, the Trustee, the NIMs Insurer, if any, the Certificate
Registrar, any Paying Agent or the Trustee may treat the Person, including a
Depository, in whose name any Certificate is registered as the owner hereof for
all purposes, and none of the Master Servicer, the Trust, the Trustee nor any
agent of any of them shall be affected by notice to the contrary.

         On any Distribution Date following the date at which the remaining
aggregate Principal Balance of the Mortgage Loans is less than 10% of the sum of
the aggregate Principal Balance of the Initial Mortgage Loans as of the Cut-off
Date plus the Original Pre-Funded Amounts, the Master Servicer may purchase, in
whole, from the Trust the Mortgage Loans at a purchase price determined as
provided in the Agreement. In the event that no such optional termination
occurs, the obligations and responsibilities created by the Agreement will
terminate upon notice to the Trustee upon the earliest of (i) the Distribution
Date on which the Certificate Principal Balances of the Regular Certificates
have been reduced to zero, (ii) the final payment or other liquidation of the
last Mortgage Loan in the Trust, (iii) the Distribution Date in February 2035.

         Capitalized terms used herein that are defined in the Agreement shall
have the meanings ascribed to them in the Agreement, and nothing herein shall be
deemed inconsistent with that meaning.

                                       3
<PAGE>

defect or deliver such missing document within such time period, the Seller
shall either repurchase or substitute for such Mortgage Loan pursuant to Section
2.03 of the Pooling and Servicing Agreement.

         The Purchaser hereby acknowledges its acceptance of all right, title
and interest to the Mortgage Loans and other property, now existing and
hereafter created, conveyed to it pursuant to Section 2.01.

         The parties hereto intend that the transaction set forth herein be a
sale by the Seller to the Purchaser of all the Seller's right, title and
interest in and to the Mortgage Loans and other property described above. In the
event the transaction set forth herein is deemed not to be a sale, the Seller,
hereby grants to the Purchaser a security interest in all of the Seller's right,
title and interest in, to and under the Mortgage Loans and other property
described above, whether now existing or hereafter created, to secure all of the
Seller's obligations hereunder; and this Agreement shall constitute a security

hereof and, to the extent necessary, in Section 2.02(iv) hereof to be recorded.
The Seller shall be required to deliver such Assignments for recording within 90
days of the Closing Date. Notwithstanding the foregoing, however, for
administrative convenience and facilitation of servicing and to reduce closing
costs, the Assignments of Mortgage shall not be required to be submitted for
recording with respect to any Mortgage Loan in any jurisdiction where the Rating
Agencies do not require recordation in order to receive the ratings on the
Certificates at the time of their initial issuance; PROVIDED, HOWEVER, each
Assignment shall be submitted for recording by the Seller in the manner
described above, at no expense to the Trust Fund or Trustee, upon the earliest
to occur of: (i) reasonable direction by Holders of Certificates entitled to at
least 25% of the Voting Rights, or the NIMS Insurer, (ii) the occurrence of a
Master Servicer Event of Termination, (iii) the occurrence of a bankruptcy,
insolvency or foreclosure relating to the Master Servicer, (iv) the occurrence
of a servicing transfer as described in Section 7.02 of the Pooling and
Servicing Agreement, (v) if the Seller is not the Master Servicer and with
respect to any one Assignment the occurrence of a bankruptcy, insolvency or
foreclosure relating to the Mortgagor under the related Mortgage and (vi) any
Mortgage Loan that is 90 days or more Delinquent and such recordation would be
necessary to facilitate conversion of the Mortgaged Property as provided herein.
Upon (a) receipt of written notice from the Trustee that recording of the
Assignments is required pursuant to one or more of the conditions (excluding (v)
and (vi) above) set forth in the preceding sentence or (b) upon the occurrence
of condition (v) or (vi) in the preceding sentence, the Seller shall be required
to deliver such Assignments for recording as provided above, promptly and in any
event within 30 days following receipt of such notice. Notwithstanding the
foregoing, if the Seller fails to pay the cost of recording the Assignments,
such expense will be paid by the Trustee and the Trustee shall be reimbursed for
such expenses by the Trust. The Seller shall furnish the Trustee, or its
designated agent, with a copy of each Assignment submitted for recording. In the
event that any such Assignment is lost or returned unrecorded because of a
defect therein, the Seller shall promptly have a substitute Assignment prepared
or have such defect cured, as the case may be, and thereafter cause each such
Assignment to be duly recorded.

         The Seller shall forward to the Purchaser original documents evidencing
an assumption, modification, consolidation or extension of any Mortgage Loan
entered into in accordance with the Pooling and Servicing Agreement within two
weeks of their execution; PROVIDED, HOWEVER, that the Seller shall provide the
Purchaser with a certified true copy of any such document submitted for
recordation within two weeks of its execution, and shall provide the original of
any document submitted for recordation or a copy of such document certified by
the appropriate public recording office to be a true and complete copy of the
original within 365 days of its submission for recordation. In the event that
the Seller cannot provide a copy of such document certified by the public
recording office within such 365 day period, the Seller shall deliver to the
Purchaser, within such 365 day period, an Officer's Certificate of the Master
Servicer which shall (A) identify the recorded document, (B) state that the
recorded document has not been delivered to the Purchaser due solely to a delay
caused by the public recording office, (C) state the amount of time generally
required by the applicable recording office to record and return a document
submitted for recordation, if known, and (D) specify the date the applicable
recorded document is expected to be delivered to the Purchaser, and, upon
receipt of a copy of such document certified by the public recording office, the
Seller shall immediately deliver such document to the Purchaser. In the event
the appropriate public recording office will not certify as to the accuracy of
such document, the Seller shall deliver a copy of such document certified by an
officer of the Seller to be a true and complete copy of the original to the
Purchaser.

                  (7)      The related Mortgage is a valid and enforceable first
or second lien on the related Mortgaged Property, which Mortgaged Property is

valid and enforceable first or second lien on the Mortgaged Property;

                  (9)      As of the last calendar day of December 2004 and with
respect to any Mortgage Loan that had a payment due on or before December 1,

Mortgage Loans have been 30 or more days delinquent in the last 12 months and
none of the Mortgage Loans have been 30 or more days delinquent for two payment

                  (10)     The Seller has not advanced funds, or induced,

                  (11)     The Seller has not impaired, waived, altered or

the exercise of any right thereunder, render either the Mortgage Note or the
Mortgage unenforceable in whole or in part, or subject to any right of


                                       7
<PAGE>


rescission, set-off, counterclaim or defense, including the defense of usury,
and no such right of rescission, set-off, counterclaim or defense has been

                  (14)     To the Seller's knowledge, there is no proceeding
pending for the total or partial condemnation and no eminent domain proceedings
pending affecting any Mortgaged Property;

                  (15)     Each Mortgage Loan is covered by either (i) a
mortgage title insurance policy or other generally acceptable form of insurance
policy customary in the jurisdiction where the Mortgaged Property is located
together with an adjustable rate rider if applicable or (ii) if generally
acceptable in the jurisdiction where the Mortgaged Property is located, an
attorney's opinion of title given by an attorney licensed to practice law in the
jurisdiction where the Mortgaged Property is located. All of the Seller's rights
under such policies, opinions or other instruments shall be transferred and
assigned to Purchaser upon sale and assignment of the Mortgage Loans hereunder.
The title insurance policy has been issued by a title insurer licensed to do
business in the jurisdiction where the Mortgaged Property is located, insuring
the original lender, its successor and assigns, as to the first or second
priority lien of the Mortgage in the original principal amount of the Mortgage
Loan, subject to the exceptions contained in such policy. The Seller is the sole
insured of such mortgagee title insurance policy, and such mortgagee title
insurance policy is in full force and effect and will be in force and effect
upon the consummation of the transactions contemplated by this Agreement.
Neither the Seller nor any affiliate of the Seller has made, and the Seller has
no knowledge of, any claims under such mortgagee title insurance policy. The
Seller is not aware of any action by a prior holder and neither the Seller nor
any affiliate of the Seller has done, by act or omission, anything which could
impair the coverage or enforceability of such mortgagee title insurance policy
or the accuracy of such attorney's opinion of title;

                  (16)     There is no material default, breach, violation or
event of acceleration existing under the related Mortgage or the related
Mortgage Note and no event which, with the passage of time or with notice and
the expiration of any grace or cure period, would constitute a material default,
breach, violation or event of acceleration, other than a payment delinquency
that is for a payment due after the date specified in (i) above. Neither the
Seller nor any affiliate of the Seller has waived any default, breach, violation
or event of acceleration;

                  (17)     With respect to any Mortgage Loan which provides for
an adjustable interest rate, all rate adjustments have been performed in
accordance with the terms of the related Mortgage Note or subsequent
modifications, if any;

                  (18)     To the Seller's knowledge, there are no delinquent
taxes, ground rents, water charges, sewer rents, assessments, insurance
premiums, leasehold payments, including assessments payable in future
installments or other outstanding charges, affecting the related Mortgaged
Property;

                  (19)     No foreclosure proceedings are pending against the
Mortgaged Property and the Mortgage Loan is not subject to any pending
bankruptcy or insolvency proceeding, and to the Seller's best knowledge, no
material litigation or lawsuit relating to the Mortgage Loan is pending;


                                       8
<PAGE>


                  (20)     The Mortgage Loan obligates the mortgagor thereunder
to maintain a hazard insurance policy ("Hazard Insurance") in an amount at least
equal to the lesser of (i) the maximum insurable value of such improvements or
(ii) the principal balance of the Mortgage Loan with a standard mortgagee
clause, in either case in an amount sufficient to avoid the application of any
"co-insurance provisions," and, if it was in place at origination of the
Mortgage Loan, flood insurance, at the mortgagor's cost and expense. If the
Mortgaged Property is in an area identified in the Federal Register by the
Federal Emergency Management Agency ("FEMA") as having special flood hazards, a
flood insurance policy is in effect which met the requirements of FEMA at the
time such policy was issued. The Mortgage obligates the Mortgagor to maintain
the Hazard Insurance, and, if applicable, flood insurance policy at the
Mortgagor's cost and expense, and on the Mortgagor's failure to do so,
authorizes the holder of the Mortgage to obtain and maintain such insurance at
the Mortgagor's cost and expense, and to seek reimbursement therefor from the
Mortgagor. The Mortgaged Property is covered by Hazard Insurance;

                  (21)     The Mortgage Note is not and has not been secured by
any collateral except the lien of the corresponding Mortgage and the security
interest of any applicable security agreement or chattel mortgage;

                  (22)     The Mortgage contains an enforceable provision for
the acceleration of the payment of the unpaid principal balance of the Mortgage
Loan in the event that the Mortgaged Property is sold or transferred without the
prior written consent of the Mortgagee thereunder. The Mortgage contains
customary and enforceable provisions such as to render the rights and remedies
of the holder thereof adequate for the realization against the Mortgaged
Property of the benefits of the security provided thereby, including (i) in the
case of a Mortgage designated as a deed of trust, by trustee's sale and (ii)
otherwise by judicial foreclosure. Since the date of origination of the Mortgage
Loan, the Mortgaged Property has not been subject to any bankruptcy proceeding
or foreclosure proceeding and the Mortgagor has not filed for protection under
applicable bankruptcy laws. There is no homestead or other exemption available
to the Mortgagor that would interfere with the right to sell the Mortgaged
Property at a trustee's sale or the right to foreclose the Mortgage. In the
event the Mortgage constitutes a deed of trust, a trustee, duly qualified under
applicable law to serve as such, as been properly designated and currently so
serves and is named in the Mortgage, and no fees or expenses are or will become
payable by Purchaser to the trustee under the deed of trust, except in
connection with a trustee's sale after default by the related Mortgagor. The
Mortgagor has not notified the Seller or any affiliate of the Seller and the
Seller has no knowledge of any relief requested or allowed to the Mortgagor
under the Servicemembers Civil Relief Act;

                  (23)     Except as set forth in the appraisal which forms part
of the related Mortgage File, the Mortgaged Property, normal wear and tear
excepted, is undamaged by waste, fire, earthquake or earth movement, windstorm,
flood, tornado or other casualty so as to affect materially and adversely the
value of the Mortgaged Property as security for the Mortgage Loan or the use for
which the premises were intended;

                  (24)     To the Seller's knowledge, there was no fraud
involved in the origination of the Mortgage Loan by the mortgagee or by the
Mortgagor, any appraiser or any other party involved in the origination of the
Mortgage Loan;


                                       9
<PAGE>


                  (25)     Each Mortgage File contains an appraisal of the
Mortgaged Property indicating the appraised value at the time of origination for
such Mortgaged Property. Each appraisal has been performed in accordance with
the provisions of the Financial Institutions Reform, Recovery and Enforcement
Act of 1989;

                  (26)     To the best of the Seller's knowledge, all parties
which have had any interest in the Mortgage Loan, whether as mortgagee,
assignee, pledgee or otherwise, are (or, during the period in which they held
and disposed of such interest, were) in compliance with any and all applicable
"doing business" and licensing requirements of the laws of the state wherein the
Mortgaged Property is located;

                  (27)     No improvements on the related Mortgaged Property
(upon which value was given) encroach on adjoining properties (and in the case
of a condominium unit, such improvements are within the project with respect to
that unit), and no improvements on adjoining properties encroach upon the
Mortgaged Property unless there exists in the Mortgage File a title Policy with
endorsements which insure against losses sustained by the insured as a result of
such encroachments;

                  (28)     Each Mortgage Loan was originated or acquired by a
savings and loan association, a savings bank, a commercial bank or similar
banking institution which is supervised and examined by a federal or state
authority, or by a mortgagee approved by the Secretary of HUD. Each Mortgage
Loan was originated substantially in accordance with the Seller's underwriting
criteria, which are at least as stringent as the underwriting criteria set forth
in the Prospectus Supplement. Each Mortgage Loan is currently being serviced by
the Seller and has been serviced by the Seller since the date of origination of
such Mortgage Loan;

                  (29)     (i) Principal payments on the Mortgage Loan commenced
no more than two months after the proceeds of the Mortgage Loan were disbursed
and (ii) each Mortgage Note is payable on the first day of each month;

                  (30)     The Mortgage Loan bears interest at the Mortgage Rate
and the Mortgage Note does not permit negative amortization. No Mortgage Loan
bearing interest at an adjustable rate permits the Mortgagor to convert the
Mortgage Loan to a fixed rate Mortgage Loan;

                  (31)     With respect to escrow deposits, if any, all such
payments are in the possession of, or under the control of, the Master Servicer
and there exist no deficiencies in connection therewith for which customary
arrangements for repayment thereof have not been made. No escrow deposits or
escrow advances or other charges or payments due the Master Servicer have been
capitalized under any Mortgage or the related Mortgage Note;

                  (32)     No Mortgage Loan contains provisions pursuant to
which scheduled payments are: (i) paid or partially paid with funds deposited in
any separate account established by the Seller, the Mortgagor, or anyone on
behalf of the Mortgagor; or (ii) paid by any source other than the Mortgagor or
contains any other similar provisions which may constitute a "buydown"
provision. The Mortgage Loan is not a graduated payment mortgage loan and the
Mortgage Loan does not have a shared appreciation or other contingent interest
feature;


                                       10
<PAGE>


                  (33)     As of the origination date of each Mortgage Loan, the
related Mortgaged Property is lawfully permitted to be occupied under applicable
law;

                  (34)     Except as disclosed in the Prospectus Supplement,
there are no proceedings or investigations pending, with respect to servicing,
collection or notification practices and with respect to origination practices,
violating any law in connection with any Mortgage Loan transferred to the
Purchaser pursuant to this Agreement, including, without limitation, usury,
truth in lending, real estate settlement procedures, consumer credit protection,
equal credit opportunity or disclosure laws. The Mortgage Loan has been serviced
in accordance with the terms of the Mortgage Note;

                  (35)     No Mortgage Loan was made in connection with (a) the

                  (b)      The Seller hereby represents and warrants to the
Purchaser, with respect to the Group I Mortgage Loans as of the Closing Date or
as of such date specifically provided herein:

                  (1)      Each Group I Mortgage Loan had a Principal Balance at
origination which conformed with Fannie Mae/Freddie Mac guidelines;

                  (2)      No borrower was encouraged or required to select a
Group I Mortgage Loan product offered by the Originator which is a higher cost
product designed for less creditworthy borrowers, unless at the time of the
Group I Mortgage Loan's origination, such borrower did not qualify taking into
account credit history and debt to income ratios for a lower cost credit product
then offered by the Originator or any affiliate of the Originator. If, at the
time of loan application, the borrower may have qualified for a lower cost
credit product then offered by any mortgage lending affiliate of the Originator,
the Originator referred the borrower's application to such affiliate for
underwriting consideration;

                  (3)      The methodology used in underwriting the extension of
credit for each Group I Mortgage Loan employs objective mathematical principles
which relate the borrower's income, assets and liabilities to the proposed
payment, in accordance with the Originator's Underwriting Guidelines, and does
not rely on the extent of the borrower's equity in the collateral as the
principal determining factor in approving such credit extension. Such
underwriting methodology confirmed that at the time of origination the borrower
had a reasonable ability to make timely payments on the Group I Mortgage Loan;

                  (4)      With respect to any Group I Mortgage Loan that
contains a provision permitting imposition of a premium upon a prepayment prior
to maturity: (i) prior to the Group I Mortgage Loan's origination, the borrower
agreed to such premium in exchange for a monetary benefit, including but not
limited to a rate or fee reduction, (ii) prior to the Group I Mortgage Loan's
origination, the borrower was offered the option of obtaining a Group I Mortgage
Loan that did not require payment of such a premium, (iii) the prepayment
premium is disclosed to the borrower in the loan documents pursuant to
applicable state and federal law, (iv) for loans originated on or after
September 1, 2004, the duration of the prepayment period shall not exceed three
(3) years from the date of the note, unless the loan was modified to reduce the
prepayment period to no more than three years from the date of the note and the
borrower was notified in


                                       13
<PAGE>


writing of such reduction in prepayment period and (v) notwithstanding any state
or federal law to the contrary, the Master Servicer shall not impose such
prepayment premium in any instance when the mortgage debt is accelerated as the
result of the borrower's default in making the loan payments;

                  (5)      No borrower was required to purchase any credit life,
disability, accident or health insurance product as a condition of obtaining the
extension of credit. No borrower obtained a prepaid single premium credit life,
disability, accident or health insurance policy in connection with the
origination of the Group I Mortgage Loan. No proceeds from any Group I Mortgage
Loan were used to purchase single premium credit insurance policies as part of
the origination of, or as a condition to closing, such Group I Mortgage Loan;

                  (6)      All points and fees related to each Group I Mortgage
Loan were disclosed in writing to the borrower in accordance with applicable
state and federal law and regulation. Except in the case of a Group I Mortgage
Loan in an original principal amount of less than $60,000 which would have
resulted in an unprofitable origination, no borrower was charged "points and
fees" (whether or not financed) in an amount greater than 5% of the principal
amount of such loan, such 5% limitation calculated in accordance with Fannie
Mae's anti-predatory lending requirements as set forth in the Fannie Mae Selling
Guide;

                  (7)      No Group I Mortgage Loan originated on or after
October 1, 2002 through March 6, 2003 is secured by a Mortgaged Property located
in the State of Georgia

                  (8)      No Mortgage Loan originated on or after March 7, 2003
is a "high cost home loan" as defined under the Georgia Fair Lending Act.

                  (9)      Each Group I Mortgage Loan is in compliance with the
anti-predatory lending eligibility for purchase requirements of the Fannie Mae
Lender Letter, LL03-00: Eligibility of Mortgages to Borrowers with Blemished
Credit Records (04/11/00) other than the requirements regarding Escrow Deposit
Accounts;

                  (10)     The Master Servicer will transmit full-file credit
reporting data for each Group I Mortgage Loan pursuant to Fannie Mae Guide
Announcement 95-19 and that for each Group I Mortgage Loan, Master Servicer
agrees it shall report one of the following statuses each month as follows: new
origination, current, delinquent (30-, 60-, 90-days, etc.), foreclosed, or
charged-off;

                  (11)     No Mortgage Loan is a "High Cost Home Loan" as
defined in New York Banking Law 6-1;

                  (12)     No Group I Mortgage Loan is a "High Cost Home Loan"
as defined in the Arkansas Home Loan Protection Act effective July 16, 2003 (Act
1340 or 2003);"

                  (13)     No Group I Mortgage Loan is a "High Cost Home Loan"
as defined in Kentucky high-cost loan statute effective June 24, 2003 (Ky. Rev.
Stat. Section 360.100);

defined in the New Jersey Home Ownership Act effective November 27, 2003
(N.J.S.A. 46; 10B-22 et seq.);

defined in the Illinois High Risk Home Loan Act effective January 1, 2004 (815
Ill. Comp. Stat. 137/1 et seq.);

                  (18)     All fees and charges (including finance charges) and
whether or not financed, assessed, collected or to be collected in connection

disclosed in writing to the borrower in accordance with applicable state and
federal law and regulation; (19) No subprime mortgage loan originated on or

and any non-subprime loans, will not impose prepayment penalties in excess of
five years;

                  (20)     With respect to each mortgage loan underlying the
security, no borrower obtained a prepaid single-premium credit-life, credit
disability, credit unemployment or credit property insurance policy in
connection with the origination of the mortgage loan;

                  (21)     With respect to any mortgage loan originated on or
after August 1, 2004 and underlying the Security, neither the related mortgage
nor the related mortgage note requires the borrower to submit to arbitration to
resolve any dispute arising out of or relating in any way to the mortgage loan
transaction;

         Section 3.03 REMEDIES FOR BREACH OF REPRESENTATIONS AND WARRANTIES. It
is understood and agreed that the representations and warranties set forth in
Sections 3.01 and 3.02 shall survive the sale of the Mortgage Loans to the
Purchaser and shall inure to the benefit of the Purchaser, notwithstanding any
restrictive or qualified endorsement on any Mortgage Note or Assignment or the
examination or lack of examination of any Mortgage File. With respect to the
representations and warranties contained herein that are made to the knowledge
or the best knowledge of the Seller or as to which the Seller has no knowledge,
if it is discovered that the substance of any such representation and warranty
is inaccurate and the inaccuracy materially and adversely affects the value of
the related Mortgage Loan, or the interest therein of the Purchaser or the
Purchaser's assignee, designee or transferee, then notwithstanding the Seller's
lack of knowledge with respect to the substance of such representation and
warranty being inaccurate at the time the representation and warranty was made,
such inaccuracy shall be deemed a breach of the applicable representation and
warranty and the Seller shall take such action described in the following
paragraphs of this Section 3.03 in respect of such Mortgage Loan. Upon discovery
by either the Seller, the Master Servicer or the Purchaser of a breach of any of
the foregoing representations and warranties that materially and adversely
affects the value of the Mortgage Loans or the interest of the Purchaser (or
which materially and adversely affects the interests of the Purchaser in the
related Mortgage Loan in the case of a representation and warranty relating to a
particular Mortgage Loan), the party discovering such breach shall give prompt
written notice to the others. It is understood by the parties hereto that a
breach of the representations and warranties made in Section 3.01(a) (45), (53),
(54) and Section 3.01 (b)(7), (8), (20), (21), (22), (23) will be deemed to
materially and adversely affect the value of the related Mortgage Loan or the
interest of the Purchaser.

         Within 120 days of the earlier of either discovery by or notice to the
Seller of any breach of a representation or warranty made by the Seller that
materially and adversely affects the value of a Mortgage Loan or the Mortgage
Loans or the interest therein of the Purchaser, the Seller shall use its best
efforts promptly to cure such breach in all material respects and, if such
breach cannot be cured, the Seller shall, at the Purchaser's option, repurchase
such Mortgage Loan at the Purchase Price. In the event that a breach shall
involve any representation or warranty set forth in Section 3.02 and such breach
cannot be cured within 120 days of the earlier of either discovery


                                       17
<PAGE>


by or notice to the Seller of such breach, all of the Mortgage Loans shall, at
the Purchaser's option, be repurchased by the Seller at the Purchase Price. The
Seller may, at the request of the Purchaser and assuming the Seller has a
Qualified Substitute Mortgage Loan, rather than repurchase a deficient Mortgage
Loan as provided above, remove such Mortgage Loan and substitute in its place a
Qualified Substitute Mortgage Loan or Loans. If the Seller does not provide a
Qualified Substitute Mortgage Loan or Loans, it shall repurchase the deficient
Mortgage Loan. Any repurchase of a Mortgage Loan(s) pursuant to the foregoing
provisions of this Section 3.03 shall occur on a date designated by the
Purchaser and shall be accomplished by deposit in accordance with Section 2.03
of the Pooling and Servicing Agreement. Any repurchase or substitution required
by this Section shall be made in a manner consistent with Section 2.03 of the
Pooling and Servicing Agreement.

         At the time of substitution or repurchase of any deficient Mortgage
Loan, the Purchaser and the Seller shall arrange for the reassignment of the
repurchased or substituted Mortgage Loan to the Seller and the delivery to the
Seller of any documents held by the Trustee relating to the deficient or
repurchased Mortgage Loan. In the event the Purchase Price is deposited in the
Collection Account, the Seller shall, simultaneously with such deposit, give
written notice to the Purchaser that such deposit has taken place. Upon such
repurchase, the Mortgage Loan Schedule shall be amended to reflect the
withdrawal of the repurchased Mortgage Loan from this Agreement.

         As to any Deleted Mortgage Loan for which the Seller substitutes a
Qualified Substitute Mortgage Loan or Loans, the Seller shall effect such
substitution by delivering to the Purchaser or its designee for such Qualified
Substitute Mortgage Loan or Loans the Mortgage Note, the Mortgage, the
Assignment and such other documents and agreements as are required by the
Pooling and Servicing Agreement, with the Mortgage Note endorsed as required
therein. The Seller shall deposit in the Collection Account the Monthly Payment
less the Servicing Fee due on such Qualified Substitute Mortgage Loan or Loans
in the month following the date of such substitution. Monthly Payments due with
respect to Qualified Substitute Mortgage Loans in the month of substitution will
be retained by the Seller. For the month of substitution, distributions to the
Purchaser will include the Monthly Payment due on such Deleted Mortgage Loan in
the month of substitution, and the Seller shall thereafter be entitled to retain
all amounts subsequently received by the Seller in respect of such Deleted
Mortgage Loan. Upon such substitution, the Qualified Substitute Mortgage Loans
shall be subject to the terms of this Agreement in all respects, and the Seller
shall be deemed to have made with respect to such Qualified Substitute Mortgage
Loan or Loans as of the date of substitution, the covenants, representations and
warranties set forth in Sections 3.01 and 3.02.

         It is understood and agreed that the representations and warranties set
forth in Section 3.01 shall survive delivery of the respective Mortgage Files to
the Trustee on behalf of the Purchaser.

         It is understood and agreed that the obligations of the Seller set
forth in Section 3.03 to cure, repurchase and substitute for a defective
Mortgage Loan and to indemnify the Purchaser as provided in Section 5.01
constitute the sole remedies of the Purchaser respecting a missing or defective
document or a breach of the representations and warranties contained in Section
3.01 or 3.02.

contesting the validity thereof in good faith by appropriate proceedings and

material fact contained in the information on any computer tape furnished to the

the Seller, its officers, directors and each person or entity who controls the
Seller, or any such person, against any and all losses, claims, damages or
liabilities, joint and several, to which the Seller or any such person or entity
may become subject, under the Securities Act or otherwise, and will reimburse
the Seller for any legal or other expenses incurred by the Seller, each officer
and director and controlling person in connection with investigating or
defending any such losses, claims, damages or liabilities insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon any untrue statement or alleged untrue statement of any
material fact contained in the Prospectus Supplement or any amendment or
supplement to the Prospectus Supplement or the omission or the alleged omission
to state therein a material fact necessary in order to make the statements in
the Prospectus Supplement or any amendment or supplement to the Prospectus
Supplement, in the light of the circumstances under which they were made, not
misleading, but only to the extent that such untrue statement or alleged untrue
statement or omission or alleged omission is not contained in the Seller
Information in the Prospectus Supplement. This indemnity agreement will be in
addition to any liability which the Purchaser may otherwise have.

                  (c)      Promptly after receipt by any indemnified party under
this Article V of notice of any claim or the commencement of any action, such
indemnified party shall, if a claim in respect thereof is to be made against any
indemnifying party under this Article V, notify the indemnifying party in
writing of the claim or the commencement of that action; PROVIDED, HOWEVER, that
the failure to notify an indemnifying party shall not relieve it from any
liability which it may have under this Article V except to the extent it has
been materially prejudiced by such failure and, provided further, that the
failure to notify any indemnifying party shall not relieve it from any liability
which it may have to any indemnified party otherwise than under this Article V.

         If any such claim or action shall be brought against an indemnified
party, and it shall notify the indemnifying party thereof, the indemnifying
party shall be entitled to participate therein and, to the extent that it
wishes, jointly with any other similarly notified indemnifying party, to assume
the defense thereof with counsel reasonably satisfactory to the indemnified
party. After notice from the indemnifying party to the indemnified party of its
election to assume the defense of such claim or action, the indemnifying party
shall not be liable to the indemnified party under this Article V for any legal
or other expenses subsequently incurred by the indemnified party in connection
with the defense thereof other than reasonable costs of investigation.

         Any indemnified party shall have the right to employ separate counsel
in any such action and to participate in the defense thereof, but the fees and
expenses of such counsel shall be at the expense of such indemnified party
unless: (i) the employment thereof has been specifically authorized by the
indemnifying party in writing; (ii) such indemnified party shall have been
advised in writing by such counsel that there may be one or more legal defenses
available to it which are different from or additional to those available to the
indemnifying party and in the reasonable judgment of such counsel it is
advisable for such indemnified party to employ


                                       20
<PAGE>


separate counsel; or (iii) the indemnifying party has failed to assume the
defense of such action and employ counsel reasonably satisfactory to the
indemnified party, in which case, if such indemnified party notifies the
indemnifying party in writing that it elects to employ separate counsel at the
expense of the indemnifying party, the indemnifying party shall not have the
right to assume the defense of such action on behalf of such indemnified party,
it being understood, however, the indemnifying party shall not, in connection
with any one such action or separate but substantially similar or related
actions in the same jurisdiction arising out of the same general allegations or
circumstances, be liable for the reasonable fees and expenses of more than one
separate firm of attorneys (in addition to local counsel) at any time for all
such indemnified parties, which firm shall be designated in writing by the
Purchaser, if the indemnified parties under this Article V consist of the
Purchaser or by the Seller, if the indemnified parties in this Article V consist
of the Seller.

         Each indemnified party, as a condition of the indemnity agreements
contained in Section 5.01 (a) and (b) hereof, shall use its best efforts to
cooperate with the indemnifying party in the defense of any such action or
claim. No indemnifying party shall be liable for any settlement of any such
action effected without its written consent (which consent shall not be
unreasonably withheld), but if settled with its written consent or if there be a
final judgment for the plaintiff in any such action, the indemnifying party
agrees to indemnify and hold harmless any indemnified party from and against any
loss or liability by reason of such settlement or judgment. Notwithstanding the
foregoing sentence, if at any time an indemnified party shall have requested an
indemnifying party to consent to a settlement of any action, the indemnifying
party agrees that it shall be liable for any settlement of any proceeding
effected without its written consent if such settlement is entered into more
than 30 days after receipt by such indemnifying party of the aforesaid request
and the indemnifying party has not previously provided the indemnified party
with written notice of its objection to such settlement. No indemnifying party
shall effect any settlement of any pending or threatened proceeding in respect
of which an indemnified party is or could have been a party and indemnity is or
could have been sought hereunder, without the written consent of such
indemnified party, unless settlement includes an unconditional release of such
indemnified party from all liability and claims that are the subject matter of
such proceeding.

                  (d)      In order to provide for just and equitable
contribution in circumstances in which the indemnity agreement provided for in
this Article is for any reason held to be unenforceable although applicable in
accordance with its terms, the Seller, on the one hand, and the Purchaser, on
the other, shall contribute to the aggregate losses, liabilities, claims,
damages and expenses of the nature contemplated by said indemnity agreement
incurred by the Seller and the Purchaser in such proportions as shall be
appropriate to reflect the relative benefits received by the Seller on the one
hand and the Purchaser on the other from the sale of the Mortgage Loans such
that the Purchaser is responsible for the lesser of (i) 0.25% thereof and (ii)
0.25% of the aggregate proceeds to the Seller from the sale of the Mortgage
Loans and the Seller shall be responsible for the balance; PROVIDED, HOWEVER,
that no person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the Securities Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation. For purposes of
this Section, each officer and director of the Purchaser and each person, if
any, who controls the Purchaser within the meaning of Section 15 of the
Securities Act shall have the same rights to contribution as the Purchaser and
each director of the Seller, each officer of the Seller,


                                       21
<PAGE>


and each person, if any, who controls the Seller within the meaning of Section
15 of the Securities Act shall have the same rights to contribution as the
Seller.

                  (e)      The Seller agrees to indemnify and to hold each of
the Purchaser, the Trustee, each of the officers and directors of each such
entity and each person or entity who controls each such entity or person and
each Certificateholder harmless against any and all claims, losses, penalties,
fines, forfeitures, legal fees and related costs, judgments, and any other
costs, fees and expenses that the Purchaser, the Trustee, or any such person or
entity and any Certificateholder may sustain in any way (i) related to the
failure of the Seller to perform its duties in compliance with the terms of this
Agreement, (ii) arising from a breach by the Seller of its representations and
warranties in Section 3.01 or 3.02 of this Agreement or (iii) related to the
origination or prior servicing of the Mortgage Loans by reason of any acts,
omissions, or alleged acts or omissions of the Seller or any servicer. The
Seller shall immediately notify the Purchaser, the Trustee and each
Certificateholder if a claim is made by a third party with respect to this
Agreement. The Seller shall assume the defense of any such claim and pay all
expenses in connection therewith, including reasonable counsel fees, and
promptly pay, discharge and satisfy any judgment or decree which may be entered
against the Purchaser, the Trustee or any such person or entity and/or any
Certificateholder in respect of such claim.

                                   ARTICLE VI.

                                   TERMINATION

         Section 6.01 TERMINATION. The respective obligations and
responsibilities of the Seller and the Purchaser created hereby shall terminate,
except for the Seller's indemnity obligations as provided herein upon the
termination of the Trust as provided in Article X of the Pooling and Servicing
Agreement.

                                  ARTICLE VII.

                            MISCELLANEOUS PROVISIONS

         Section 7.01 AMENDMENT. This Agreement may be amended from time to
time, with the consent of the NIMS Insurer, if any, by the Originator, the
Seller and the Purchaser, by written agreement signed by the Originator, the
Seller and the Purchaser.

         Section 7.02 GOVERNING LAW. This Agreement shall be governed by and
construed in accordance with the laws of the State of New York and the
obligations, rights and remedies of the parties hereunder shall be determined in
accordance with such laws.

         Section 7.03 NOTICES. All demands, notices and communications hereunder
shall be in writing and shall be deemed to have been duly given if personally
delivered at or mailed by registered mail, postage prepaid, addressed as
follows:

         if to the Seller:

                  Option One Mortgage Corporation
                  3 Ada


                                       22
<PAGE>


                  Irvine, CA 92618
                  Attention: William L. O'Neill

or such other address as may hereafter be furnished to the Purchaser in writing
by the Seller.

         if to the Purchaser:

                  Option One Mortgage Acceptance Corporation
                  3 Ada
                  Irvine, CA 92618
                  Attention: William L. O'Neill

or such other address as may hereafter be furnished to the Seller in writing by
the Purchaser.

         Section 7.04 SEVERABILITY OF PROVISIONS. If any one or more of the
covenants, agreements, provisions of terms of this Agreement shall be held
invalid for any reason whatsoever, then such covenants, agreements, provisions
or terms shall be deemed severable from the remaining covenants, agreements,
provisions or terms of this Agreement and shall in no way affect the validity of
enforceability of the other provisions of this Agreement.

         Section 7.05 COUNTERPARTS. This Agreement may be executed in one or
more counterparts and by the different parties hereto on separate counterparts,
each of which, when so executed, shall be deemed to be an original and such
counterparts, together, shall constitute one and the same agreement.

         Section 7.06 FURTHER AGREEMENTS. The Purchaser and the Seller each
agree to execute and deliver to the other such additional documents, instruments
or agreements as may be necessary or reasonable and appropriate to effectuate
the purposes of this Agreement or in connection with the issuance of any series
of Certificates representing interests in the Mortgage Loans.

         Without limiting the generality of the foregoing, as a further
inducement for the Purchaser to purchase the Mortgage Loans from the Seller, the
Seller will cooperate with the Purchaser in connection with the sale of any of
the securities representing interests in the Mortgage Loans. In that connection,
the Seller will provide to the Purchaser any and all information and appropriate
verification of information, whether through letters of its auditors and counsel
or otherwise, as the Purchaser shall reasonably request and will provide to the
Purchaser such additional representations and warranties, covenants, opinions of
counsel, letters from auditors, and certificates of public officials or officers
of the Seller as are reasonably required in connection with such transactions
and the offering of investment grade securities rated by the Rating Agencies.

         Section 7.07 INTENTION OF THE PARTIES. It is the intention of the
parties that the Purchaser is purchasing, and the Seller is selling, the
Mortgage Loans rather than pledging the Mortgage Loans to secure a loan by the
Purchaser to the Seller. Accordingly, the parties hereto each intend to treat
the transaction for federal income tax purposes and all other purposes as a sale
by the Seller, and a purchase by the Purchaser, of the Mortgage Loans. The
Purchaser will have the right to review the Mortgage Loans and the related
Mortgage Files to determine the


                                       23
<PAGE>


characteristics of the Mortgage Loans which will affect the federal income tax
consequences of owning the Mortgage Loans and the Seller will cooperate with all
reasonable requests made by the Purchaser in the course of such review.

         Section 7.08 SUCCESSORS AND ASSIGNS, ASSIGNMENT OF PURCHASE AGREEMENT.
This Agreement shall bind and inure to the benefit of and be enforceable by the
Seller, the Purchaser, the Trustee and the NIMs Insurer, if any. The NIMs
Insurer, if any, shall be a third party beneficiary hereof and may enforce the
terms hereof as if a party hereto. The obligations of the Seller under this
Agreement cannot be assigned or delegated to a third party without the consent
of the Purchaser which consent shall be at the Purchaser's sole discretion,
except that the Purchaser acknowledges and agrees that the Seller may assign its
obligations hereunder to any Person into which the Seller is merged or any
corporation resulting from any merger, conversion or consolidation to which the
Seller is a party or any Person succeeding to the business of the Seller. The
parties hereto acknowledge that the Purchaser is acquiring the Mortgage Loans
for the purpose of contributing them to a trust that will issue a series of
Certificates representing undivided interests in such Mortgage Loans. As an
inducement to the Purchaser to purchase the Mortgage Loans, the Seller
acknowledges and consents to the assignment by the Purchaser to the Trustee of
all of the Purchaser's rights against the Seller pursuant to this Agreement
insofar as such rights relate to Mortgage Loans transferred to the Trustee and
to the enforcement or exercise of any right or remedy against the Seller
pursuant to this Agreement by the Trustee. Such enforcement of a right or remedy
by the Trustee shall have the same force and effect as if the right or remedy
had been enforced or exercised by the Purchaser directly.

         Section 7.09 SURVIVAL. The representations and warranties set forth in
Sections 3.01 and 3.02 and the provisions of Article V hereof shall survive the
purchase of the Mortgage Loans hereunder.

                           ) ss..
COUNTY OF                  )

                  The undersigned, being first duly sworn, deposes and says as
follows:

                  1. The undersigned is an officer of Option One Mortgage
Corporation, the proposed Transferee of an Ownership Interest in a Residual
Certificate (the "CERTIFICATE") issued pursuant to the Pooling and Servicing
Agreement dated as of January 1, 2005 (the "AGREEMENT"), among Option One
Mortgage Acceptance Corporation, as depositor (the "DEPOSITOR"), Option One
Mortgage Corporation, as master servicer (the " MASTER SERVICER") and Wells
Fargo Bank, N.A., as trustee (the "TRUSTEE"). Capitalized terms used, but not
defined herein or in Exhibit 1 hereto, shall have the meanings ascribed to such
terms in the Agreement. The Transferee has authorized the undersigned to make
this affidavit on behalf of the Transferee for the benefit of the Depositor and
the Trustee.

                  2. The Transferee is, as of the date hereof, and will be, as
of the date of the Transfer, a Permitted Transferee. The Transferee is acquiring
its Ownership Interest in the Certificate for its own account. The Transferee
has no knowledge that any such affidavit is false.

                  3. The Transferee has been advised of, and understands that
(i) a tax will be imposed on Transfers of the Certificate to Persons that are
not Permitted Transferees; (ii) such tax will be imposed on the transferor, or,
if such Transfer is through an agent (which includes a broker, nominee or
middleman) for a Person that is not a Permitted Transferee, on the agent; and
(iii) the Person otherwise liable for the tax shall be relieved of liability for
the tax if the subsequent Transferee furnished to such Person an affidavit that
such subsequent Transferee is a Permitted Transferee and, at the time of
Transfer, such Person does not have actual knowledge that the affidavit is
false.

                  4. The Transferee has been advised of, and understands that a
tax will be imposed on a "pass-through entity" holding the Certificate if at any
time during the taxable year of the pass-through entity a Person that is not a
Permitted Transferee is the record holder of an interest in such entity. The
Transferee understands that such tax will not be imposed for any period with
respect to which the record holder furnishes to the pass-through entity an
affidavit that such record holder is a Permitted Transferee and the pass-through
entity does not have actual knowledge that such affidavit is false. (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 and, except as may be provided in Treasury Regulations,
persons holding interests in pass-through entities as a nominee for another
Person.)



                                  EXHIBIT K-1
<PAGE>

                  5. The Transferee has reviewed the provisions of Section
5.02(d) of the Agreement and understands the legal consequences of the
acquisition of an Ownership Interest in the Certificate including, without
limitation, the restrictions on subsequent Transfers and the provisions
regarding voiding the Transfer and mandatory sales. The Transferee expressly
agrees to be bound by and to abide by the provisions of Section 5.02(d) of the
Agreement and the restrictions noted on the face of the Certificate. The
Transferee understands and agrees that any breach of any of the representations
included herein shall render the Transfer to the Transferee contemplated hereby
null and void.

                  6. The Transferee agrees to require a Transfer Affidavit from
any Person to whom the Transferee attempts to Transfer its Ownership Interest in
the Certificate, and in connection with any Transfer by a Person for whom the
Transferee is acting as nominee, trustee or agent, and the Transferee will not
Transfer its Ownership Interest or cause any Ownership Interest to be
Transferred to any Person that the Transferee knows is not a Permitted
Transferee. In connection with any such Transfer by the Transferee, the
Transferee agrees to deliver to the Trustee a certificate substantially in the
form set forth as Exhibit L to the Agreement (a "TRANSFEROR CERTIFICATE") to the
effect that such Transferee has no actual knowledge that the Person to which the
Transfer is to be made is not a Permitted Transferee.

                  7. The Transferee has historically paid its debts as they have
come due, intends to pay its debts as they come due in the future, and
understands that the taxes payable with respect to the Certificate may exceed
the cash flow with respect thereto in some or all periods and intends to pay
such taxes as they become due. The Transferee does not have the intention to
impede the assessment or collection of any tax legally required to be paid with
respect to the Certificate.

                  8. The Transferee's taxpayer identification number is
33-0536622.

                  9. The Transferee is a U.S. Person as defined in Code Section
7701(a)(30).

                  10. The Transferee is aware that the Certificate may be a
"noneconomic residual interest" within the meaning of proposed Treasury
regulations promulgated pursuant to 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 was to impede the assessment or collection of tax.

                  11. The Transferee will not cause income from the Certificate
to be attributable to a foreign permanent establishment or fixed base, within
the meaning of an applicable income tax treaty, of the Transferee or any other
U.S. person.

                  12. Check one of the following:

                  |_| The present value of the anticipated tax liabilities
associated with holding the Certificate, as applicable, does not exceed the sum
of:

                  (i)      the present value of any consideration given to the
                           Transferee to acquire such Certificate;



                                  EXHIBIT K-2
<PAGE>

                  (ii)     the present value of the expected future
                           distributions on such Certificate; and

                  (iii)    the present value of the anticipated tax savings
                           associated with holding such Certificate as the
                           related REMIC generates losses.

                  For purposes of this calculation, (i) the Transferee is
assumed to pay tax at the highest rate currently specified in Section 11(b) of
the Code (but the tax rate in Section 55(b)(1)(B) of the Code may be used in
lieu of the highest rate specified in Section 11(b) of the Code if the
Transferee has been subject to the alternative minimum tax under Section 55 of
the Code in the preceding two years and will compute its taxable income in the

respect of periods included in the year covered by this annual report, of Option
One Mortgage Loan Trust 2005-1, Asset-Backed Certificates, Series 2005-1;

                  2. Based on my knowledge, the information in these reports,
taken as a whole, does not contain any untrue statement of a material fact or
omit to state a material fact necessary to make the statements made, in light of
the circumstances under which such statements were made, not misleading as of
the last day of the period covered by this annual report;

                  3. Based on my knowledge, the distribution or servicing
information required to be provided to the trustee by the master servicer under
the pooling and servicing, or similar, agreement, for inclusion in these reports
is included in these reports;

                  4. Based on my knowledge and upon the annual compliance
statement included in the report and required to be delivered to the trustee in
accordance with the terms of the pooling and servicing, or similar, agreement,
and except as disclosed in the reports, the master servicer has fulfilled its
obligations under the servicing agreement; and

                  5. The reports disclose all significant deficiencies relating
to the master servicer's compliance with the minimum servicing standards based
upon the report provided by an independent public accountant, after conducting a
