        This Pooling and Servicing   Agreement,   effective as of January 1, 2005,

among RESIDENTIAL ASSET SECURITIES CORPORATION,   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 U.S. BANK NATIONAL ASSOCIATION,   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

thirteen   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   Hedge   Agreements)   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) The Class A, Class M and Class B Certificates   will   represent   ownership of

    REMIC II Regular   Interests   together with certain   rights to payments to be

    made from amounts   received under the related Hedge   Agreement which will be

    deemed   made for   federal   income   tax   purposes   outside of REMIC II by the

    holder of the Class SB Certificates as the owner of the Hedge Agreement.

(2) The REMIC II 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 the lesser of (i) LIBOR plus the   applicable   Margin and

    (ii) the REMIC Net WAC Rate and the provisions for the payment of Basis Risk

    Shortfalls herein, which payments will not be part of the entitlement of the

    REMIC II 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 II Regular   Interest is entitled and

    from amounts received under the Hedge Agreement, which will not be a part of

    their ownership of the REMIC II 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 represent   ownership of two REMIC II Regular Interests,   a

    principal only regular   interest   designated REMIC II Regular Interest SB-PO

    and an interest only regular   interest   designated REMIC II Regular Interest

    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 Hedge

    Agreements   shall be outside   and apart   from its rights   under the REMIC II

    Regular Interests SB-IO and SB-PO.

 

In consideration of the mutual agreements herein contained,   the Depositor,   the

Master Servicer and the Trustee agree as follows:

Section 1.01.   Definitions.

 

        Whenever used in this Agreement, the following words and phrases, unless

the   context   otherwise   requires,   shall have the   meanings   specified   in this

Article.

 

        Accrued Certificate Interest: With respect to each Distribution Date and

each   Class   of   Class   A   Certificates,    Class   M   Certificates   and   Class   B

Certificates, interest accrued during the related Interest Accrual Period on the

Certificate   Principal   Balance thereof   immediately   prior to such Distribution

Date at the related Pass-Through Rate for that Distribution Date.

 

        The amount of Accrued Certificate Interest on each Class of Certificates

shall be reduced by the amount of Prepayment   Interest Shortfalls on the related

Mortgage   Loans   during the prior   calendar   month to the extent not   covered by

Compensating   Interest pursuant to Section 3.16, and by Relief Act Shortfalls on

the related   Mortgage Loans during the related Due Period.   All such   reductions

with respect to the Mortgage Loans will be allocated   among the   Certificates in

proportion   to the   amounts   of   Accrued   Certificate   Interest   payable on such

Certificates on such Distribution Date absent such reductions.

 

        Accrued Certificate Interest on each Class of Class A Certificates, each

Class of Class M Certificates   and the Class B Certificates for any Distribution

Date shall also be reduced by any interest shortfalls resulting from the failure

of the Hedge Agreements   Provider to make the related required Hedge Payment for

such   Distribution   Date,   with all such   reductions on the Class A Certificates

allocated to the Class A Certificates on a pro rata basis,   based on the portion

of the Class A Hedge   Payment   each   such   Class was   entitled   to,   but did not

receive,   on such   Distribution   Date,   and all such   reductions   on the Class M

Certificates and Class B Certificates   allocated to the Class M Certificates and

Class   B   Certificates   on a pro   rata   basis,   based   on   the   portion   of   the

Subordinate   Hedge Payment each such Class was entitled to, but did not receive,

on such Distribution Date.

 

        Accrued Certificate   Interest for any Distribution Date shall further be

reduced by the   interest   portion of Realized   Losses   allocated to any Class of

Certificates pursuant to Section 4.05.

 

        Accrued Certificate Interest shall accrue on the basis of a 360-day year

and the actual number of days in the related Interest Accrual Period.

 

        With respect to each   Distribution   Date and the Class SB   Certificates,

interest   accrued   during the preceding   Interest   Accrual Period at the related

Pass-Through   Rate on the   Notional   Amount as specified   in the   definition   of

Pass-Through   Rate,   immediately prior to such Distribution Date, reduced by any

interest   shortfalls   with respect to the Mortgage Loans,   including   Prepayment

Interest Shortfalls to the extent not covered by Compensating   Interest pursuant

to Section 3.16 or by Excess Cash Flow pursuant to Section   4.02(c)(v) and (vi).

Accrued   Certificate   Interest on the Class SB Certificates   shall accrue on the

basis of a 360-day   year and the actual   number of days in the related   Interest

Accrual Period.

 

        Adjusted   Mortgage Rate:   With respect to any Mortgage Loan and any date

of determination, the Mortgage Rate borne by the related Mortgage Note, less the

rate at which the related Subservicing Fee accrues.

Master Servicer, pursuant to Section 4.04.

 

        Affiliate:   With respect to any Person,   any other   Person   controlling,

        P0 = the aggregate   principal   balance of the REMIC I Regular   Interests

LT1, LT2, LT3 and LT4 after   distributions and the allocation of Realized Losses

on the prior Distribution Date.

 

        P1 = the aggregate   principal   balance of the REMIC I Regular   Interests

LT1, LT2, LT3 and LT4 after   distributions and the allocation of Realized Losses

to be made on such Distribution Date.

 

        AP = P0 - P1 = the aggregate of the REMIC I Regular   Interests LT1, LT2,

LT3 and LT4 Principal Reduction Amounts.

 

              =the aggregate of the principal   portions of Realized Losses to be

allocated to, and the principal distributions to be made on, the Certificates on

such Distribution   Date (including   distributions of accrued and unpaid interest

on the Class SB Certificates for prior Distribution Dates).

to amounts   distributed and Realized Losses allocated on the prior   Distribution

Date.

 

                                       31

<PAGE>

 

        R1 = the Net WAC Cap Rate (stated as a monthly rate) after giving effect

to   amounts   to be   distributed   and   Realized   Losses to be   allocated   on such

Distribution Date.

 

        a = (Y2 + Y3)/P0.   The initial value of a on the Closing Date for use on

the first Distribution Date shall be 0.0001.

Distribution Date and (ii) the aggregate   Certificate Principal Balance for such

Class after   distributions   and the allocation of Realized   Losses to be made on

such Distribution Date and (B) R1*P1.

 

         Then, based on the foregoing definitions:

 

        AY1 =   AP - AY2 - AY3 - AY4;

 

        AY2 =   (a/2){( a0R1 - a1R0)/R0R1};

 

        AY3 =   aAP - AY2; and

 

        AY4 =   AY3.

 

   if both AY2 and AY3, as so determined, are non-negative numbers.   Otherwise:

 

        (1) If AY2, as so determined, is negative, then

 

        AY2 = 0;

 

        AY3 = a{a1R0P0 - a0R1P1}/{a1R0};

 

        AY4 = AY3; and

 

        AY1 = AP - AY2 - AY3 - AY4.

 

        (2) If AY3, as so determined, is negative, then
