        This Pooling and Servicing Agreement,   effective as of November 1, 2005,
among RESIDENTIAL ASSET MORTGAGE PRODUCTS, INC., as the depositor (together with
its permitted   successors and assigns,   the   "Depositor"),   RESIDENTIAL   FUNDING
CORPORATION,   as master   servicer   (together   with its permitted   successors and
assigns,   the "Master   Servicer"),   and   JPMORGAN   CHASE BANK,   N.A.,   a banking
association   organized under the laws of the United States, as trustee (together
with its permitted successors and assigns, the "Trustee").


                              PRELIMINARY STATEMENT:

        The   Depositor   intends   to   sell   mortgage   asset-backed    pass-through
certificates   (collectively,   the   "Certificates"),   to be issued   hereunder   in
sixteen   classes,   which in the aggregate   will   evidence the entire   beneficial
ownership   interest in the Mortgage Loans (as defined   herein) and certain other
related assets.

                                     REMIC I

        As provided   herein,   the REMIC   Administrator   will make an election to
treat the segregated pool of assets consisting of the Mortgage Loans and certain
other   related   assets   (exclusive   of the Swap Account and the Swap   Agreement)
subject   to this   Agreement   as a real   estate   mortgage   investment   conduit (a
"REMIC") for federal   income tax purposes,   and such   segregated   pool of assets
will be designated as "REMIC I." The Class R-I   Certificates   will represent the
sole   Class   of   "residual   interests"   in   REMIC I for   purposes   of the   REMIC
Provisions (as defined herein) under federal income tax law. The following table
irrevocably   sets forth the   designation,   remittance rate (the   "Uncertificated
REMIC I Pass-Through   Rate") and initial   Uncertificated   Principal   Balance for
each of the "regular   interests"   in REMIC I (the "REMIC I Regular   Interests").
The   "latest   possible   maturity   date"   (determined    solely   for   purposes   of
satisfying   Treasury   regulation Section   1.860G-1(a)(4)(iii))   for each REMIC I
Regular   Interest   shall   be the   Maturity   Date.   None of the   REMIC I   Regular
Interests will be certificated.

(1) This   Class of   Certificates   represents   ownership   of a REMIC III   Regular
    Interest   together   with (i)   certain   rights   to   payments   to be made from
    amounts   received   under the Swap   Agreement   which will be deemed   made for
    federal income tax purposes   outside of REMIC III by the holder of the Class
    SB   Certificates   as the owner of the Swap Agreement and (ii) the obligation
    to pay the Class IO   Distribution   Amount.   Any amount   distributed   on this
    Class of   Certificates   on any   Distribution   Date in excess   of the   amount
    distributable on the related REMIC III Regular Interest on such Distribution
    Date shall be treated   for federal   income tax   purposes as having been paid
    from the Swap Account and any amount distributable on such REMIC III Regular
    Interest on such Distribution Date in excess of the amount   distributable on
    such Class of   Certificates   on such   Distribution   Date shall be treated as
    having   been   paid to the   Swap   Account,   all   pursuant   to and as   further
    provided in Section 4.08 hereof.
(2) The REMIC III Regular   Interests   ownership of which is   represented   by the
    Class A, Class M and Class B   Certificates,   will   accrue   interest at a per
    annum rate   equal to LIBOR plus the   applicable   Margin,   each   subject to a
    payment cap as described in the   definition of   "Pass-Through   Rate" and the
    provisions for the payment of Basis Risk Shortfalls   herein,   which payments
    will not be part of the   entitlement   of the   REMIC   III   Regular   Interests
    related to such Certificates.
(3) The   Class A,   Class M and Class B   Certificates   will   also   entitle   their
    holders to   certain   payments   from the Holder of the Class SB   Certificates
    from amounts to which the related REMIC III Regular Interest is entitled and
    from amounts received under the Swap Agreement,   which will not be a part of
    their ownership of the REMIC III Regular Interests.
(4) The   Class   SB   Certificates   will   accrue   interest   as   described   in   the
    definition of Accrued Certificate   Interest.   The Class SB Certificates will
    not accrue interest on their   Certificate   Principal   Balance.   The Class SB
    Certificates   will be   comprised   of two   REMIC   III   regular   interests,   a
    principal   only   regular   interest   designated   SB-PO and an   interest   only
    regular interest   designated SB-IO,   which will be entitled to distributions
    as set forth herein.   The rights of the Holder of the Class SB   Certificates
    to   payments   from the Swap   Agreement   shall be outside   and apart from its
    rights under the REMIC III Regular Interests SB-IO and SB-PO.
(5) REMIC III Regular   Interest IO will be held as an asset of the Swap   Account
    established by the Trustee.  

(6)   For federal   income tax   purposes,   REMIC III Regular   Interest IO will not
     have a   Pass-Through   Rate,   but will be   entitled   to 100% of the   amounts
     distributed on REMIC II Regular Interest LT-IO.

(7)   For federal   income tax   purposes,   REMIC III Regular   Interest IO will not
     have an Uncertificated   Principal Balance,   but will have a notional amount
     equal to the   Uncertificated   Notional Amount of REMIC II Regular   Interest
     LT-IO.

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