        This is a Series   Supplement,   dated as of August   1, 2006 (the   "Series
Supplement"), to the Standard Terms of Pooling and Servicing Agreement, dated as
of March 1, 2006 and attached as Exhibit Four hereto (the "Standard   Terms" and,
together with this Series Supplement,   the "Pooling and Servicing   Agreement" or
"Agreement"),   among RESIDENTIAL   ACCREDIT LOANS, 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 DEUTSCHE BANK TRUST COMPANY AMERICAS,   as
Trustee and   supplemental   interest   trust trustee   (together with its permitted
successors   and assigns,   the "Trustee"   and the   "Supplemental   Interest   Trust
Trustee"), respectively.

                             PRELIMINARY STATEMENT:

        The   Company    intends   to   sell   mortgage    asset-backed    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 Mortgage Loans.

        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.   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 this Series Supplement.

                                     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 Supplemental   Interest Trust Account, the
Swap Agreement and the SB-AM 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 Class R-I Certificates will not bear interest or have a Certificate
Principal   Balance.   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.
