        This is a Series   Supplement,   dated as of December 1, 2005 (the "Series
Supplement"), to the Standard Terms of Pooling and Servicing Agreement, dated as
of May 1, 2005 and   attached as Exhibit Four hereto (the   "Standard   Terms" and,
together with this Series Supplement,   the "Pooling and Servicing   Agreement" or
"Agreement"),   among   RESIDENTIAL   FUNDING   MORTGAGE   SECURITIES I, INC., as the
company   (together with its permitted   successors and assigns,   the   "Company"),
RESIDENTIAL FUNDING CORPORATION, as master servicer (together with its permitted
successors   and   assigns,   the   "Master   Servicer"),    and   U.S.   BANK   NATIONAL
ASSOCIATION, as Trustee (together with its permitted successors and assigns, the
"Trustee").

                              PRELIMINARY STATEMENT

        The   Company    intends   to   sell   Mortgage    Pass-Through    Certificates
(collectively, the "Certificates"),   to be issued hereunder in multiple classes,
which in the aggregate will evidence the entire beneficial ownership interest in
the   Trust   Fund.   As   provided   herein,   the REMIC   Administrator   will make an
election   to   treat   the   entire   segregated   pool of   assets   described   in the
definition of Trust Fund, and subject to this Agreement   (including the Mortgage
Loans but excluding the Initial Monthly Payment Fund), as a real estate mortgage
investment   conduit   (the   "REMIC")   for federal   income tax   purposes   and such
segregated   pool of assets will be designated   as "REMIC I." The   Uncertificated
REMIC Regular I Interests   will be "regular   interests" in REMIC I and the Class
R-I Certificates   will be the sole class of "residual   interests" in REMIC I for
purposes of the REMIC   Provisions   (as defined   herein).   A   segregated   pool of
assets   consisting   of the   Uncertificated   REMIC I   Regular   Interests   will be
designated as "REMIC II," and the REMIC Administrator will make a separate REMIC
election   with   respect   thereto.    The   Class   A-1    Certificates,    Class   A-2
Certificates,    Class   A-3   Certificates,   Class   A-4   Certificates,   Class   A-5
Certificates,    Class   A-6   Certificates,   Class   A-7   Certificates,   Class   A-8
Certificates,   Class A-9   Certificates,   Class   A-10   Certificates,   Class   A-11
Certificates,   the Class A-12   Certificates,   Class A-P Certificates,   Class M-1
Certificates,    Class   M-2   Certificates,   Class   M-3   Certificates,   Class   B-1
Certificates,    Class   B-2    Certificates,    Class   B-3    Certificates   and   the
Uncertificated REMIC II Regular Interests Z will be "regular interests" in REMIC
II and   the   Class   R-II   Certificates   will   be the   sole   class   of   "residual
interests"   therein   for   purposes   of   the   REMIC   Provisions.   The   Class   A-V
Certificates   will   represent the entire   beneficial   ownership   interest in the
Uncertificated REMIC I Regular Interests Z.

        The terms and provisions of the Standard   Terms are hereby   incorporated
by reference herein as though set forth in full herein. If any term or provision
contained   herein shall   conflict   with or be   inconsistent   with any   provision
contained   in the   Standard   Terms,   the terms   and   provisions   of this   Series
Supplement   shall govern.   Any   cross-reference   to a section of the Pooling and
Servicing   Agreement,   to the extent the terms of the Standard   Terms and Series
Supplement conflict with respect to that section,   shall be a cross-reference to
the   related   section   of the   Series   Supplement.   All   capitalized   terms   not
otherwise   defined   herein   shall have the   meanings   set forth in the   Standard
Terms. The Pooling and Servicing   Agreement shall be dated as of the date of the
Series Supplement.

                outstanding   with a Certificate   Principal   Balance   greater than
               zero:

                      (a) in the case of the Class of   Subordinate   Certificates
               then   outstanding   with the Highest Priority and each other Class
                of   Subordinate   Certificates   for which the   related   Prepayment

               Balances   immediately   prior   to such   date of (1) the   Class   of
               Subordinate    Certificates   then   outstanding   with   the   Highest
               Priority and (2) all other   Classes of   Subordinate   Certificates
               for which the respective   Prepayment   Distribution   Triggers have
               been satisfied; and

               Section 4.02 of this Series Supplement (determined without regard
               to   the   proviso   to the   definition   of   "Subordinate   Principal
               Distribution   Amount") would result in a distribution   in respect
               of principal of any Class or Classes of Subordinate   Certificates
               in an amount   greater than the   remaining   Certificate   Principal
                Balance thereof (any such class, a "Maturing   Class"),   then: (a)
               the   Prepayment   Distribution   Percentage of each Maturing   Class
               shall be   reduced to a level   that,   when   applied   as   described
               above, would exactly reduce the Certificate   Principal Balance of
               such Class to zero; (b) the Prepayment Distribution Percentage of
               each other Class of Subordinate   Certificates   (any such Class, a
               "Non-Maturing   Class") shall be   recalculated   in accordance with
               the   provisions in paragraph   (ii) above,   as if the   Certificate
               Principal Balance of each Maturing Class had been reduced to zero
               (such percentage as recalculated, the "Recalculated Percentage");

               aggregate   percentage,   shall be allocated among the Non-Maturing
               Classes    in    proportion    to   their    respective    Recalculated

               for   purposes   of   such    Distribution    Date,    the    Prepayment
               Distribution Percentage of each Non-Maturing Class shall be equal
               to the sum of (1) the Prepayment Distribution Percentage thereof,
               calculated in accordance   with the   provisions in paragraph   (ii)
               above as if the   Certificate   Principal   Balance of each Maturing
                Class   had not   been   reduced   to   zero,   plus   (2)   the   related

Section 1.02    Use of Words and Phrases.

        "Herein," "hereby," "hereunder," "hereof," "hereinbefore," "hereinafter"
and other   equivalent   words refer to the Pooling and   Servicing   Agreement as a
whole. All references herein to Articles, Sections or Subsections shall mean the
corresponding   Articles,   Sections and   Subsections in the Pooling and Servicing
Agreement.   The   definitions   set forth herein include both the singular and the
plural.

Section 1.03    Determination of LIBOR.

        LIBOR   applicable to the   calculation of the   Pass-Through   Rates on the
Adjustable   Rate   Certificates,   if any, for any Interest   Accrual Period (other
than the initial   Interest Accrual Period) will be determined on each LIBOR Rate
Adjustment Date.

        On each LIBOR Rate Adjustment Date (other than for the initial   Interest
Accrual   Period),   LIBOR   shall be   established   by the   Trustee   and, as to any
Interest Accrual Period,   will equal the rate for one month United States dollar
deposits that appears on the Telerate Screen Page 3750 as of 11:00 a.m.,   London
time, on the LIBOR Rate Adjustment   Date.   "Telerate Screen Page 3750" means the
display   designated as page 3750 on the Telerate   Service (or such other page as
may   replace   page 3750 on that   service for the   purpose of   displaying   London
interbank   offered   rates of major   banks).   If the rate does not appear on such
page (or any other   page as may   replace   that page on that   service,   or if the
service is no longer offered,   LIBOR shall be so established by use of any other
service   for   displaying   LIBOR or   comparable   rates as may be   selected by the
Trustee   after   consultation   with the   Master   Servicer),   the rate will be the
Reference Bank Rate.   The "Reference   Bank Rate" will be determined on the basis
of the rates at which   deposits in U.S.   Dollars   are   offered by the   reference
banks (which shall be any three major banks that are engaged in   transactions in
the London interbank market, selected by the Trustee after consultation with the
Master   Servicer) as of 11:00 a.m.,   London time,   on the LIBOR Rate   Adjustment
Date to prime banks in the London   interbank market for a period of one month in
amounts   approximately equal to the aggregate   Certificate   Principal Balance of
the Adjustable Rate Certificates then outstanding.   The Trustee will request the
principal London office of each of the reference banks to provide a quotation of
its rate. If at least two such   quotations   are   provided,   the rate will be the
arithmetic   mean of the quotations   rounded up to the next multiple of 1/16%. If
on such date fewer than two quotations are provided as requested,   the rate will
be the   arithmetic   mean of the rates   quoted by one or more major   banks in New
York City,   selected by the Trustee after consultation with the Master Servicer,
as of 11:00 a.m., New York City time, on such date for loans in U.S.   Dollars to
leading European banks for a period of one month in amounts   approximately equal
to   the   aggregate    Certificate    Principal   Balance   of   the   Adjustable   Rate
Certificates then outstanding.   If no such quotations can be obtained,   the rate
will be LIBOR for the prior Distribution Date, or in the case of the first LIBOR
Rate Adjustment Date, 4.16%; provided,   however, if, under the priorities listed
previously in this   paragraph,   LIBOR for a Distribution   Date would be based on
LIBOR for the previous Distribution Date for the third consecutive   Distribution
Date, the Trustee, after consultation with the Master Servicer,   shall select an
alternative   comparable   index over which the Trustee   has no control,   used for
determining   one-month Eurodollar lending rates that is calculated and published
or otherwise made available by an independent party.

        The   establishment   of LIBOR by the Trustee on any LIBOR Rate Adjustment
Date and the Master Servicer's subsequent   calculation of the Pass-Through Rates
applicable to each of the Adjustable Rate Certificates for the relevant Interest
Accrual Period, in the absence of manifest error, will be final and binding.

        Promptly   following each LIBOR Rate   Adjustment   Date, the Trustee shall
supply the Master   Servicer   with the results of its   determination   of LIBOR on
such date.   Furthermore,   the Trustee   will supply to any   Certificateholder   so
requesting by telephone the   Pass-Through   Rates on each of the Adjustable   Rate
Certificates   for the current and the   immediately   preceding   Interest   Accrual
Period.

        and   interest   as of the Cut-off   Date and no Mortgage   Loan has been so
        Delinquent   more than once in the   12-month   period prior to the Cut-off
        Date;

(ii)     The   information   set forth in Exhibit One hereto   with   respect to each
        Mortgage   Loan or the   Mortgage   Loans,   as the case may be, is true and

(iv)     To the best of the Company's knowledge, if a Mortgage Loan is secured by

        95.00% and 90.01%, (b) at least 25% of such balance if the Loan-to-Value
        Ratio is between 90.00% and 85.01%, and (c) at least 12% of such balance

        whose   claims-paying   abilities are currently   acceptable to each Rating
        Agency;

        maintain   such   insurance   at   the   Mortgagor's    expense   and   to   seek
        reimbursement therefor from the Mortgagor;

        related    Mortgage    Loan    that   the    Mortgaged    Property    would   be
        owner-occupied and therefore would not be an investor property as of the
        date of origination of such Mortgage Loan. No Mortgagor is a corporation
        or a partnership;

(xi)     None of the Mortgage Loans is a Buydown Mortgage Loan;

(xii)    Each   Mortgage   Loan   constitutes   a qualified   mortgage   under   Section

        1.860G-2(a)(1);

(xiii)   A policy of title   insurance   was   effective   as of the   closing of each
        Mortgage   Loan and is valid and   binding   and   remains in full force and
        effect, unless the Mortgaged Properties are located in the State of Iowa
        and an   attorney's   certificate   has been   provided as   described in the
        Program Guide;

        thereof),   the related Seller has represented   that either (a) the value
        of the related   Mortgaged   Property as of the date the Mortgage Loan was

        Loan-to-Value   Ratio of the Mortgage Loan as of the date of   origination
        of   the   Mortgage   Loan   generally   meets   the   Company's    underwriting
        guidelines;

(xvi)    Interest on each   Mortgage   Loan is calculated on the basis of a 360-day
        year consisting of twelve 30-day months;

(xvii)   None of the   Mortgage   Loans   contains   in the related   Mortgage   File a
        Destroyed Mortgage Note; and

(xviii) None of the   Mortgage   Loans   are   Pledged   Asset   Loans   or   Additional

It is understood and agreed that the representations and warranties set forth in
this Section 2.03(b) shall survive delivery of the respective   Mortgage Files to
the Trustee or any Custodian.

        Upon discovery by any of the Company, the Master Servicer,   the Trustee,
or any Custodian of a breach of any of the   representations   and   warranties set
forth   in this   Section   2.03(b)   that   materially   and   adversely   affects   the
interests of the   Certificateholders in any Mortgage Loan, the party discovering
such breach shall give prompt written notice to the other parties (any Custodian
being so obligated under a Custodial Agreement);   provided, however, that in the
event of a breach   of the   representation   and   warranty   set   forth in   Section
2.03(b)(xii),   the party   discovering   such breach shall give such notice within
five days of discovery. Within 90 days of its discovery or its receipt of notice
of   breach,   the   Company   shall   either   (i) cure such   breach in all   material
respects or (ii) purchase such Mortgage Loan from the Trust Fund at the Purchase
Price and in the manner set forth in Section   2.02;   provided   that the   Company
shall have the option to   substitute   a Qualified   Substitute   Mortgage   Loan or
Loans   for such   Mortgage   Loan if such   substitution   occurs   within   two years
following the Closing Date;   provided that if the omission or defect would cause
the Mortgage Loan to be other than a "qualified   mortgage" as defined in Section
860G(a)(3) of the Code,   any such cure or   repurchase   must occur within 90 days
from the date   such   breach   was   discovered.   Any   such   substitution   shall be
effected   by the   Company   under the same terms and   conditions   as   provided in
Section 2.04 for   substitutions   by   Residential   Funding.   It is understood and
agreed that the   obligation of the Company to cure such breach or to so purchase
or   substitute   for any Mortgage Loan as to which such a breach has occurred and
is continuing shall constitute the sole remedy   respecting such breach available
to the   Certificateholders   or the Trustee on behalf of the   Certificateholders.
Notwithstanding   the   foregoing,   the   Company   shall   not be   required   to cure
breaches   or   purchase   or   substitute   for   Mortgage   Loans as provided in this
Section   2.03(b) if the   substance of the breach of a   representation   set forth
above also constitutes fraud in the origination of the Mortgage Loan.

ARTICLE III

                          ADMINISTRATION AND SERVICING

                                OF MORTGAGE LOANS

Section 3.01    Master Servicer to Act as Servicer.

(a) The Master   Servicer   shall   service and   administer   the Mortgage   Loans in
accordance   with the terms of this Agreement and the respective   Mortgage Loans,
following such procedures as it would employ in its good faith business judgment
and which are normal and usual in its general mortgage servicing activities, and
in the case of the Mortgage Loans being subserviced by Wells Fargo, if any, such
procedures that comply with applicable federal, state and local law and that are
in accordance with accepted   mortgage   servicing   practices of prudent   mortgage
lending   institutions which service loans of the same type as the Mortgage Loans
in the   jurisdiction   in which the related   Mortgaged   Property is located,   and
shall have full power and   authority,   acting alone or through   Subservicers   as
provided in Section 3.02,   to do any and all things which it may deem   necessary
or desirable in   connection   with such   servicing   and   administration.   Without
limiting the generality of the foregoing, the Master Servicer in its own name or
in the name of a Subservicer   is hereby   authorized and empowered by the Trustee
when the Master   Servicer or the   Subservicer,   as the case may be,   believes it
appropriate   in its best   judgment,   to execute   and   deliver,   on behalf of the
Certificateholders   and the Trustee or any of them,   any and all   instruments of
satisfaction or cancellation,   or of partial or full release or discharge, or of
consent to assumption or modification in connection with a proposed   conveyance,
or of   assignment   of any   Mortgage   and Mortgage   Note in   connection   with the
repurchase   of a Mortgage   Loan and all other   comparable   instruments,   or with
respect to the   modification   or   re-recording   of a Mortgage for the purpose of
correcting the Mortgage,   the subordination of the lien of the Mortgage in favor
of a public utility company or government   agency or unit with powers of eminent
domain,   the   taking   of a   deed   in   lieu   of   foreclosure,   the   commencement,
prosecution   or   completion   of   judicial   or   non-judicial    foreclosure,    the
conveyance of a Mortgaged   Property to the related   Insurer,   the acquisition of
any property   acquired by   foreclosure   or deed in lieu of   foreclosure,   or the
management,   marketing and conveyance of any property acquired by foreclosure or
deed in lieu of foreclosure   with respect to the Mortgage Loans and with respect
to the Mortgaged   Properties.   The Master   Servicer   further is   authorized   and
empowered by the Trustee, on behalf of the   Certificateholders   and the Trustee,
in its own name or in the name of the   Subservicer,   when the Master Servicer or
the   Subservicer,   as the case may be,   believes it is   appropriate   in its best
judgment to register   any   Mortgage   Loan on the   MERS(R)   System,   or cause the
removal from the   registration   of any Mortgage Loan on the MERS(R)   System,   to
execute and deliver, on behalf of the Trustee and the   Certificateholders or any
of them, any and all instruments of assignment and other comparable   instruments
with respect to such   assignment   or   re-recording   of a Mortgage in the name of
MERS,   solely as nominee for the Trustee and its   successors   and   assigns.   Any
expenses   incurred in   connection   with the actions   described in the   preceding
sentence   shall be borne by the   Master   Servicer   in   accordance   with   Section
3.16(c), with no right of reimbursement;   provided, that if, as a result of MERS
discontinuing   or becoming unable to continue   operations in connection with the
MERS System,   it becomes necessary to remove any Mortgage Loan from registration
on the MERS System and to arrange for the assignment of the related Mortgages to
the   Trustee,   then any related   expenses   shall be   reimbursable   to the Master
Servicer.   Notwithstanding the foregoing, subject to Section 3.07(a), the Master
Servicer   shall not permit any   modification   with respect to any Mortgage   Loan
that would both   constitute a sale or exchange of such   Mortgage Loan within the
meaning   of   Section   1001 of the   Code   and any   proposed,   temporary   or final
regulations   promulgated   thereunder   (other than in connection   with a proposed
conveyance   or   assumption   of such Mortgage Loan that is treated as a Principal
Prepayment   in Full   pursuant   to Section   3.13(d)   hereof)   and cause any REMIC
formed under the Series Supplement to fail to qualify as a REMIC under the Code.
The Trustee   shall   furnish the Master   Servicer with any powers of attorney and
other   documents   necessary   or   appropriate   to enable the Master   Servicer   to
service and administer the Mortgage   Loans.   The Trustee shall not be liable for
any action   taken by the Master   Servicer   or any   Subservicer   pursuant to such
powers of attorney.   In servicing and administering any Nonsubserviced   Mortgage
Loan,   the Master   Servicer   shall,   to the extent   not   inconsistent   with this
Agreement,   comply with the Program   Guide as if it were the   originator of such
Mortgage Loan and had retained the servicing   rights and   obligations in respect
thereof.   In connection with servicing and administering the Mortgage Loans, the
Master   Servicer   and any   Affiliate   of the   Master   Servicer   (i) may   perform
services such as   appraisals   and   brokerage   services that are not   customarily
provided by servicers   of mortgage   loans,   and shall be entitled to   reasonable
compensation   therefor in accordance   with Section 3.10 and (ii) may, at its own
discretion and on behalf of the Trustee,   obtain credit   information in the form
of a "credit score" from a credit repository.

(b)      (See Section 3.01(b) - (c) of the Standard Terms)

Section                3.02 Subservicing   Agreements   Between Master Servicer and
                      Subservicers;   Enforcement of   Subservicers'   and Sellers'
                      Obligations.

(a) The Master Servicer may continue in effect   Subservicing   Agreements entered
into by Residential Funding and Subservicers prior to the execution and delivery
of   this   Agreement,   and   may   enter   into   new   Subservicing   Agreements   with
Subservicers,   for   the   servicing   and   administration   of all or   some   of the
Mortgage Loans. Each Subservicer shall be either (i) an institution the accounts
of which are   insured by the FDIC or (ii)   another   entity   that   engages in the
business of originating or servicing mortgage loans, and in either case shall be
authorized   to   transact   business   in the state or states in which the   related
Mortgaged   Properties   it is to   service   are   situated,   if and   to the   extent
required by applicable law to enable the   Subservicer to perform its obligations
hereunder and under the   Subservicing   Agreement,   and in either case shall be a
Freddie Mac,   Fannie Mae or HUD approved   mortgage   servicer.   In addition,   any
Subservicer   of a   Mortgage   Loan   insured   by the FHA   must be an   FHA-approved
servicer,   and any Subservicer of a Mortgage Loan guaranteed by the VA must be a
VA-approved   servicer.   Each Subservicer of a Mortgage Loan shall be entitled to
receive and retain,   as provided in the related   Subservicing   Agreement   and in
Section 3.07, the related Subservicing Fee from payments of interest received on
such Mortgage   Loan after payment of all amounts   required to be remitted to the
Master   Servicer in respect of such Mortgage Loan. For any Mortgage Loan that is
a Nonsubserviced Mortgage Loan, the Master Servicer shall be entitled to receive
and retain an amount equal to the   Subservicing   Fee from   payments of interest.
Unless the context otherwise   requires,   references in this Agreement to actions
taken or to be taken by the Master   Servicer in   servicing   the   Mortgage   Loans
include   actions taken or to be taken by a   Subservicer   on behalf of the Master
Servicer.   Each Subservicing Agreement will be upon such terms and conditions as
are generally required by, permitted by or consistent with the Program Guide and
are not   inconsistent   with this   Agreement   and as the Master   Servicer and the
Subservicer have agreed;   provided that, the Subservicing   Agreement between the
Master   Servicer and Wells Fargo, if any, will be upon such terms and conditions
as are   consistent   with   this   Agreement   and as the   Master   Servicer   and the
Subservicer   have agreed,   which may not be consistent   with the Program   Guide.
With the   approval   of the Master   Servicer,   a   Subservicer   may   delegate   its
servicing obligations to third-party servicers, but such Subservicer will remain
obligated under the related   Subservicing   Agreement.   The Master Servicer and a
Subservicer   may   enter   into    amendments    thereto   or   a   different   form   of
Subservicing   Agreement,   and the form   referred   to or   included in the Program
Guide is merely provided for information and shall not be deemed to limit in any
respect the discretion of the Master   Servicer to modify or enter into different
Subservicing   Agreements;    provided,   however,   that   any   such   amendments   or
different   forms shall be   consistent   with and not violate   the   provisions   of
either this   Agreement or the Program   Guide in a manner which would   materially
and adversely affect the interests of the Certificateholders.   The Program Guide
and any other   Subservicing   Agreement   entered into between the Master Servicer
and any Subservicer shall require the Subservicer to accurately and fully report
its borrower credit files to each of the Credit Repositories in a timely manner.

Section 3.03    Successor Subservicers. (See Section 3.03 of the Standard Terms)

Section 3.04 Liability of the Master Servicer. (See Section 3.04 of the Standard
        Terms)

Section 3.05 No   Contractual   Relationship   Between   Subservicer   and Trustee or
        Certificateholders. (See Section 3.05 of the Standard Terms)

        Account. (See Section 3.07 of the Standard Terms)

Section 3.08    Subservicing Accounts; Servicing Accounts.

(a) In those cases where a Subservicer   is servicing a Mortgage Loan pursuant to
a   Subservicing   Agreement,   the Master   Servicer   shall cause the   Subservicer,
pursuant to the   Subservicing   Agreement,   to establish and maintain one or more
Subservicing   Accounts which shall be an Eligible Account or, if such account is
not an Eligible Account, shall generally satisfy the requirements of the Program
Guide and be otherwise acceptable to the Master Servicer and each Rating Agency.
The   Subservicer   will be   required   thereby   to deposit   into the   Subservicing
Account on a daily basis,   or with respect to the Mortgage Loans   subserviced by
Wells Fargo,   if any,   within two (2) Business Days of receipt,   all proceeds of
Mortgage   Loans   received by the   Subservicer,   less its   Subservicing   Fees and
unreimbursed   advances and expenses, to the extent permitted by the Subservicing
Agreement.   If the Subservicing   Account is not an Eligible Account,   the Master
Servicer   shall be deemed to have received   such monies upon receipt   thereof by
the   Subservicer.   The   Subservicer   shall not be   required   to   deposit   in the
Subservicing Account payments or collections in the nature of prepayment charges
or late   charges or   assumption   fees.   On or before the date   specified   in the
Program   Guide,   but in no event later than the   Determination   Date, the Master
Servicer shall cause the Subservicer, pursuant to the Subservicing Agreement, to
remit to the Master Servicer for deposit in the Custodial Account all funds held
in the Subservicing   Account with respect to each Mortgage Loan serviced by such
Subservicer   that are   required   to be   remitted   to the   Master   Servicer.   The
Subservicer will also be required,   pursuant to the Subservicing   Agreement,   to
advance on such   scheduled   date of   remittance   amounts   equal to any scheduled
monthly installments of principal and interest less its Subservicing Fees on any
Mortgage   Loans for which   payment   was not   received by the   Subservicer.   This
obligation to advance with respect to each Mortgage Loan will continue up to and
including   the   first of the   month   following   the date on   which   the   related
Mortgaged   Property   is sold at a   foreclosure   sale or is acquired by the Trust
Fund by deed in lieu of foreclosure or otherwise.   All such advances received by
the Master Servicer shall be deposited promptly by it in the Custodial Account.

Section 3.09   Access to Certain   Documentation   and   Information   Regarding   the
        Mortgage Loans. (See Section 3.09 of the Standard Terms)

Section 3.10    Permitted Withdrawals from the Custodial Account.

(a)      The Master   Servicer   may,   from time to time as provided   herein,   make
        withdrawals   from the   Custodial   Account of amounts on deposit   therein
        pursuant to Section 3.07 that are attributable to the Mortgage Loans for
        the following purposes:

        or otherwise reimbursable pursuant to the terms of this Agreement,   such
        withdrawal   right   being   limited to   amounts   received   on the   related
        Mortgage Loans   (including,   for this purpose,   REO Proceeds,   Insurance
        Proceeds,   Liquidation   Proceeds   and   proceeds   from the   purchase of a
        Mortgage Loan pursuant to Section 2.02,   2.03, 2.04, 4.07 or 9.01) which
        represent (A) Late   Collections   of Monthly   Payments for which any such
        advance   was   made   in the   case of   Subservicer   Advances   or   Advances
        pursuant   to Section   4.04 and (B)   recoveries   of amounts in respect of
        which such advances were made in the case of Servicing Advances;

        by such Subservicer) out of each payment received by the Master Servicer
        on account of interest on a Mortgage   Loan as   contemplated   by Sections
        3.14 and 3.16,   an amount   equal to that   remaining   portion of any such
         payment as to interest   (but not in excess of the   Servicing Fee and the
        Subservicing Fee, if not previously retained) which, when deducted, will
        result in the remaining   amount of such interest   being   interest at the
        Net   Mortgage   Rate   (or   Modified   Net   Mortgage   Rate in the case of a
        Modified   Mortgage   Loan) on the amount   specified   in the   amortization
        schedule of the related   Mortgage Loan as the principal   balance thereof
        at the beginning of the period   respecting   which such interest was paid
        after giving effect to any previous Curtailments;

        which   the   related   Stated   Principal   Balance   or   Purchase   Price   is
        determined;

(vii)    to reimburse   itself or the related   Subservicer for any   Nonrecoverable

        Agreements;   Certain   Assignments.   (See   Section   3.13 of the   Standard
        Terms)

Section 3.14    Realization Upon Defaulted Mortgage Loans.

(a) The Master   Servicer shall   foreclose upon or otherwise   comparably   convert
(which may include an REO Acquisition) 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.   Alternatively,   the Master   Servicer   may take other
actions in respect of a defaulted Mortgage Loan, which may include (i) accepting
a short sale (a payoff of the   Mortgage   Loan for an amount   less than the total
amount   contractually   owed in   order   to   facilitate   a sale   of the   Mortgaged
Property by the   Mortgagor) or permitting a short   refinancing   (a payoff of the
Mortgage   Loan for an amount less than the total   amount   contractually   owed in
order to facilitate   refinancing   transactions   by the Mortgagor not involving a
sale of the Mortgaged   Property),   (ii)   arranging for a repayment plan or (iii)
agreeing to a modification   in accordance   with Section 3.07. In connection with
such   foreclosure   or other   conversion or action,   the Master   Servicer   shall,
consistent   with Section 3.11,   follow such practices and procedures as it shall
deem   necessary   or   advisable,   as shall be   normal   and   usual in its   general
mortgage   servicing   activities   and as shall be   required or   permitted   by the
Program   Guide,   as applicable;   provided that the Master   Servicer shall not be
liable in any respect   hereunder if the Master   Servicer is acting in connection
with any such   foreclosure   or other   conversion   in a manner that is consistent
with the provisions of this Agreement.   The Master Servicer,   however, shall not
be   required   to expend   its own funds or incur   other   reimbursable   charges in
connection   with   any   foreclosure,    or   attempted   foreclosure   which   is   not
completed,   or towards the restoration of any property unless it shall determine
(i) that such   restoration   and/or   foreclosure   will   increase   the proceeds of
liquidation   of the   Mortgage   Loan to   Holders of   Certificates   of one or more
Classes after reimbursement to itself for such expenses or charges and (ii) that
such expenses or charges will be recoverable to it through Liquidation Proceeds,
Insurance Proceeds, or REO Proceeds (respecting which it shall have priority for
purposes of   withdrawals   from the Custodial   Account   pursuant to Section 3.10,
whether or not such expenses and charges are actually   recoverable   from related
Liquidation Proceeds,   Insurance Proceeds or REO Proceeds). In the event of such
a determination   by the Master Servicer   pursuant to this Section   3.14(a),   the
Master Servicer shall be entitled to   reimbursement   of such amounts pursuant to
Section 3.10.

        In addition to the   foregoing,   the Master   Servicer   shall use its best
reasonable   efforts to realize upon any   Additional   Collateral   for such of the
Additional Collateral 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; provided that the Master Servicer shall not, on behalf
of the Trustee, obtain title to any such Additional Collateral as a result of or
in lieu of the disposition   thereof or otherwise;   and provided further that (i)
the Master Servicer shall not proceed with respect to such Additional Collateral
in any manner   that would   impair the   ability to recover   against   the   related
Mortgaged   Property,   and (ii) the Master   Servicer   shall   proceed with any REO
Acquisition in a manner that preserves the ability to apply the proceeds of such
Additional   Collateral   against amounts owed under the defaulted   Mortgage Loan.
Any proceeds realized from such Additional   Collateral (other than amounts to be
released to the Mortgagor or the related guarantor in accordance with 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   and to the   terms   and   conditions   of any   security   agreement,
guarantee   agreement,   mortgage or other agreement   governing the disposition of
the proceeds of such Additional   Collateral) shall be deposited in the Custodial
Account,   subject to   withdrawal   pursuant to Section   3.10.   Any other   payment
received by the Master Servicer in respect of such Additional   Collateral   shall
be deposited in the Custodial Account subject to withdrawal   pursuant to Section
3.10.

        For so long as the   Master   Servicer   is the Master   Servicer   under the
Credit Support Pledge   Agreement and any of the Mortgage Loans are Pledged Asset
Loans,   the Master   Servicer   shall   perform   its   obligations   under the Credit
Support Pledge   Agreement in accordance with such agreement and in a manner that
is in the best interests of the Certificateholders. Further, the Master Servicer
shall use its best   reasonable   efforts to realize   upon any Pledged   Assets for
such of the Pledged   Asset 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;   provided that the Master Servicer shall not,
on behalf of the Trustee, obtain title to any such Pledged Assets as a result of
or in lieu of the disposition   thereof or otherwise;   and provided   further that
(i) the Master Servicer shall not proceed with respect to such Pledged Assets in
any   manner   that would   impair the   ability   to   recover   against   the   related
Mortgaged   Property,   and (ii) the Master   Servicer   shall   proceed with any REO
Acquisition in a manner that preserves the ability to apply the proceeds of such
Pledged   Assets   against   amounts owed under the defaulted   Mortgage   Loan.   Any
proceeds realized from such Pledged Assets (other than amounts to be released to
the Mortgagor or the related   guarantor in accordance   with   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
and to the terms and conditions of any security agreement,   guarantee agreement,
mortgage or other   agreement   governing the   disposition of the proceeds of such
Pledged   Assets)   shall   be   deposited   in the   Custodial   Account,   subject   to
withdrawal   pursuant to Section 3.10.   Any other payment   received by the Master
Servicer in respect of such Pledged   Assets shall be deposited in the   Custodial
Account subject to withdrawal pursuant to Section 3.10.

        Concurrently   with the   foregoing,   the Master   Servicer   may pursue any
remedies that may be available in connection   with a breach of a   representation
and warranty with respect to any such Mortgage Loan in accordance   with Sections
2.03 and 2.04.   However,   the Master   Servicer   is not   required   to continue to
pursue both foreclosure (or similar remedies) with respect to the Mortgage Loans
and remedies in connection with a breach of a representation and warranty if the
Master Servicer determines in its reasonable   discretion that one such remedy is
more likely to result in a greater   recovery as to the Mortgage   Loan.   Upon the
occurrence of a Cash   Liquidation or REO   Disposition,   following the deposit in
the Custodial Account of all Insurance Proceeds,   Liquidation Proceeds and other
payments and recoveries   referred to in the definition of "Cash   Liquidation" or
"REO   Disposition,"   as   applicable,   upon   receipt   by the   Trustee   of written
notification of such deposit signed by a Servicing   Officer,   the Trustee or any
Custodian,   as the case may be, shall release to the Master Servicer the related
Mortgage   File and the Trustee   shall   execute and deliver such   instruments   of
transfer or   assignment   prepared by the Master   Servicer,   in each case without
recourse,   as shall be necessary to vest in the Master Servicer or its designee,
as the case may be, the related Mortgage Loan, and thereafter such Mortgage Loan
shall not be part of the Trust Fund.   Notwithstanding the foregoing or any other
provision of this   Agreement,   in the Master   Servicer's   sole   discretion   with
respect   to any   defaulted   Mortgage   Loan or REO   Property   as to either of the
following provisions, (i) a Cash Liquidation or REO Disposition may be deemed to
have occurred if substantially all amounts expected by the Master Servicer to be
received in connection with the related defaulted   Mortgage Loan or REO Property
have been   received,   and (ii) for   purposes   of   determining   the amount of any
Liquidation Proceeds,   Insurance Proceeds, REO Proceeds or any other unscheduled
collections   or the amount of any Realized   Loss,   the Master   Servicer may take
into account minimal amounts of additional   receipts   expected to be received or
any   estimated   additional   liquidation   expenses   expected   to be   incurred   in
connection with the related defaulted Mortgage Loan or REO Property.

(b) (See Section 3.14(b) - (c) of the Standard Terms)

        (d) The proceeds of any Cash Liquidation, REO Disposition or purchase or
repurchase of any Mortgage Loan pursuant to the terms of this Agreement, as well
as any recovery (other than Subsequent   Recoveries)   resulting from a collection
of Liquidation Proceeds,   Insurance Proceeds or REO Proceeds, will be applied in
the following order of priority:   first, to reimburse the Master Servicer or the
related   Subservicer in accordance with Section   3.10(a)(ii) and, in the case of
Wells Fargo as a Subservicer,   if applicable,   to reimburse such Subservicer for
any Subservicing Fees payable therefrom;   second, to the   Certificateholders   to
the extent of accrued and unpaid   interest on the Mortgage Loan, and any related
REO Imputed   Interest,   at the Net   Mortgage   Rate (or the Modified Net Mortgage
Rate in the case of a Modified   Mortgage   Loan),   to the Due Date in the related
Due   Period   prior to the   Distribution   Date on which   such   amounts   are to be
distributed;   third, to the Certificateholders as a recovery of principal on the
Mortgage Loan (or REO Property) (provided that if any such Class of Certificates
to which   such   Realized   Loss was   allocated   is no   longer   outstanding,   such
subsequent   recovery shall be distributed to the persons who were the Holders of
such Class of Certificates   when it was retired);   fourth, to all Servicing Fees
and   Subservicing   Fees   payable   therefrom   (and the   Master   Servicer   and the
Subservicer   shall have no claims for any deficiencies with respect to such fees
which result from the foregoing allocation); and fifth, to Foreclosure Profits.
