        This   Pooling and   Servicing   Agreement,   effective   as of July 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 national

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   Hedge   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

Date. None of the REMIC I Regular Interests will be certificated.

(1) The Class A and Class M Certificates   will   represent   ownership of REMIC II

Regular   Interests   together   with   certain   rights to   payments to be made from

amounts received under the 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 and   Class   M

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 Cap 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 and Class M   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 Agreement 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:

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

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 and

Class M   Certificates   for any   Distribution   Date   shall also be reduced by any

interest   shortfalls   resulting from the failure of the Hedge Agreement Provider

to make the required   Hedge Payment for such   Distribution   Date,   with all such

reductions   allocated to the Class A Certificates   and Class M Certificates on a

pro rata basis,   based on the portion of the 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.

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 to the extent not covered by Compensating   Interest pursuant

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

(vii). 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.

 

        Adjustment   Date:   With respect to each   adjustable-rate   Mortgage Loan,

each date set forth in the related   Mortgage   Note on which an adjustment to the

interest rate on such Mortgage Loan becomes effective.

        For purposes of the succeeding formulas the following symbols shall have

the meanings set forth below:

 

        Y1 = the aggregate principal balance of the REMIC I Regular Interest LT1

after distributions on the prior Distribution Date.

distributions on the prior Distribution Date.

 

        Y4 = the   principal   balance of the REMIC I Regular   Interest   LT4 after

distributions on the prior Distribution Date (note: Y3 = Y4).

        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,

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

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

on the Class SB Certificates for prior Distribution Dates).

 

        R0 = the Net WAC Cap Rate (stated as a monthly rate) after giving effect

to amounts   distributed and Realized Losses allocated on the prior   Distribution

Date.

than the Class SB Certificates, of the product for each Class of (i) the monthly

interest   rate (as limited by the REMIC Net WAC Rate,   if   applicable)   for such

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:
