         I.       RFC has entered into contracts ("Seller  Contracts") with various  seller/servicers,  pursuant to
which such seller/servicers sell to RFC mortgage loans.

         II.      The Company wishes to purchase from RFC certain  Mortgage Loans (as hereinafter  defined) sold to
RFC pursuant to the Seller Contracts.

         III.     The  Company,  RFC, as master  servicer  and U.S.  Bank  National  Association,  as trustee  (the
"Trustee"),  are entering  into a Series  Supplement,  dated as of July 1, 2006 (the "Series  Supplement"),  to the
Standard Terms of Pooling and Servicing  Agreement,  dated as of June 1, 2006 (together with the Series Supplement,
the "Pooling and  Servicing  Agreement"),  pursuant to which the Company  proposes to issue  Mortgage  Pass-Through
Certificates,  Series 2006-S6 (the  "Certificates")  consisting of classes  designated as the Class A-1, Class A-2,
Class A-3, Class A-4, Class A-5,  Class A-6, Class A-7, Class A-8, Class A-9, Class A-10,  Class A-11,  Class A-12,

         IV.      In connection with the purchase of the Mortgage  Loans,  the Company will assign to RFC the Class

         V.       In connection with the purchase of the Mortgage Loans and the issuance of the  Certificates,  RFC
wishes to make certain  representations  and  warranties  to the Company and to assign  certain of its rights under
the Seller  Contracts to the  Company,  and the Company  wishes to assume  certain of RFC's  obligations  under the
Seller Contracts.

         VI.      The  Company  and RFC intend that the  conveyance  by RFC to the Company of all its right,  title
and interest in and to the Mortgage Loans pursuant to this Agreement  shall  constitute a purchase and sale and not
a loan.

         NOW  THEREFORE,  in  consideration  of the  recitals  and the  mutual  promises  herein and other good and
valuable consideration, the parties agree as follows:

Section 1.          All capitalized  terms used but not defined herein shall have the meanings  assigned thereto in
the Pooling and Servicing Agreement.

Section 2.          Concurrently  with the  execution  and  delivery  hereof,  RFC hereby  assigns  to the  Company
without  recourse all of its right,  title and interest in and to the Mortgage  Loans,  including  all interest and
principal,  and with  respect  to the Sharia  Mortgage  Loans,  all  amounts  in  respect  of profit  payments  and
acquisition  payments,  received on or with respect to the Mortgage  Loans after July 1, 2006 (other than  payments
of  principal  and  interest,  and with  respect to the Sharia  Mortgage  Loans,  all  amounts in respect of profit
payments and acquisition  payments,  due on the Mortgage Loans in July 2006). In  consideration of such assignment,
RFC  or  its  designee  will  receive  from  the  Company  in  immediately  available  funds  an  amount  equal  to
$570,408,085.04  plus the Class A-P  Certificates,  the Class A-V  Certificates  and a de  minimis  portion  of the
Retained  Certificates.  In connection with such assignment and at the Company's  direction,  RFC has in respect of
each  Mortgage Loan endorsed the related  Mortgage  Note (other than any Destroyed  Mortgage  Note) to the order of
the Trustee and delivered an assignment of mortgage or security  instrument,  as applicable,  in recordable form to
the  Trustee  or its  agent.  A  "Destroyed  Mortgage  Note"  means a  Mortgage  Note the  original  of  which  was
permanently lost or destroyed.

         RFC and the Company agree that the sale of each Pledged Asset Loan  pursuant to this  Agreement  will also
constitute  the  assignment,  sale,  setting-over,  transfer and conveyance to the Company,  without  recourse (but
subject  to  RFC's  covenants,  representations  and  warranties  specifically  provided  herein),  of all of RFC's
obligations  and all of RFC's  right,  title and  interest  in, to and under,  whether now  existing  or  hereafter
acquired  as  owner  of  such  Pledged  Asset  Loan  with  respect  to any  and  all  money,  securities,  security
entitlements,  accounts,  general  intangibles,  payment  intangibles,  instruments,  documents,  deposit accounts,
certificates of deposit,  commodities contracts,  and other investment property and other property of whatever kind
or description  consisting of,  arising from or related to,  (i) the Credit Support Pledge  Agreement,  the Funding
and Pledge  Agreement  among the Mortgagor or other Person  pledging the related  Pledged Assets (the  "Customer"),
Combined  Collateral LLC and National  Financial  Services  Corporation,  and the Additional  Collateral  Agreement
between GMAC Mortgage  Corporation and the Customer  (collectively,  the "Assigned  Contracts"),  (ii) all  rights,
powers  and  remedies  of RFC as  owner  of such  Pledged  Asset  Loan  under or in  connection  with the  Assigned
Contracts,  whether  arising  under the terms of such  Assigned  Contracts,  by  statute,  at law or in equity,  or
otherwise  arising  out of any  default  by the  Mortgagor  under or in  connection  with the  Assigned  Contracts,
including  all rights to exercise  any election or option or to make any  decision or  determination  or to give or
receive any notice, consent,  approval or waiver thereunder,  (iii) the Pledged Amounts and all money,  securities,
security  entitlements,  accounts,  general  intangibles,  payment  intangibles,  instruments,  documents,  deposit
accounts,  certificates of deposit,  commodities  contracts,  and other  investment  property and other property of
whatever kind or description and, all cash and non-cash proceeds of the sale,  exchange,  or redemption of, and all
stock or conversion rights, rights to subscribe,  liquidation dividends or preferences,  stock dividends, rights to
interest,  dividends,  earnings,  income, rents, issues, profits,  interest payments or other distributions of cash
or other  property  that  secures a Pledged  Asset  Loan,  (iv) all  documents,  books and records  concerning  the
foregoing  (including all computer  programs,  tapes,  disks and related items containing any such information) and
(v) all insurance  proceeds  (including  proceeds from the Federal Deposit Insurance  Corporation or the Securities
Investor  Protection  Corporation or any other insurance  company) of any of the foregoing or replacements  thereof
or substitutions therefor,  proceeds of proceeds and the conversion,  voluntary or involuntary, of any thereof. The
foregoing  transfer,  sale,  assignment  and  conveyance  does not  constitute and is not intended to result in the
creation,  or an assumption by the Company,  of any  obligation of RFC, or any other Person in connection  with the
Pledged Assets or under any agreement or instrument  relating  thereto,  including any obligation to the Mortgagor,
other than as owner of the Pledged Asset Loan.

         The  Company  and RFC  intend  that the  conveyance  by RFC to the  Company  of all its  right,  title and
interest in and to the Mortgage  Loans  pursuant to this  Section 2  shall be, and be  construed  as, a sale of the
Mortgage Loans by RFC to the Company.  It is,  further,  not intended that such conveyance be deemed to be a pledge
of the Mortgage  Loans by RFC to the Company to secure a debt or other  obligation  of RFC.  However,  in the event
that the  Mortgage  Loans are held to be property of RFC, or if for any reason this  Agreement is held or deemed to
create a security interest in the Mortgage Loans,  then it is intended that (a) this  Agreement shall be a security
agreement  within the  meaning  of  Articles 8  and 9 of the  Minnesota  Uniform  Commercial  Code and the  Uniform
Commercial Code of any other  applicable  jurisdiction;  (b) the  conveyance  provided for in this Section shall be
deemed to be, and hereby is, a grant by RFC to the  Company of a security  interest  in all of RFC's  right,  title
and  interest,  whether  now  owned or  hereafter  acquired,  in and to any and all  general  intangibles,  payment
intangibles,  accounts, chattel paper, instruments,  documents,  money, deposit accounts,  certificates of deposit,
goods,  letters of credit,  advices of credit and  investment  property  consisting of, arising from or relating to
any of the following:  (A) the Mortgage Loans,  including  (i) with  respect to each Cooperative  Loan, the related
Mortgage Note,  Security  Agreement,  Assignment of Proprietary Lease,  Cooperative Stock Certificate,  Cooperative
Lease,  any insurance  policies and all other  documents in the related  Mortgage  File,  (ii) with respect to each
Sharia  Mortgage Loan, the related Sharia  Mortgage Loan Security  Instrument,  Sharia  Mortgage Loan  Co-Ownership
Agreement,  Obligation to Pay, Assignment  Agreement and Amendment of Security  Instrument,  any insurance policies
and all other  documents in the related  Mortgage  File and  (iii) with  respect to each Mortgage Loan other than a
Cooperative  Loan or a Sharia Mortgage Loan, the related  Mortgage Note, the Mortgage,  any insurance  policies and
all other  documents in the related  Mortgage  File,  (B) all  monies due or to become due pursuant to the Mortgage
Loans in accordance  with the terms thereof and (C) all  proceeds of the conversion,  voluntary or involuntary,  of
the foregoing into cash, instruments,  securities or other property,  including without limitation all amounts from
time to time held or invested in the  Certificate  Account or the Custodial  Account,  whether in the form of cash,
instruments,  securities or other property;  (c) the possession by the Trustee, the Custodian or any other agent of
the  Trustee  of  Mortgage  Notes or such  other  items of  property  as  constitute  instruments,  money,  payment
intangibles,  negotiable  documents,  goods,  deposit  accounts,  letters of credit,  advices of credit  investment
property or chattel paper shall be deemed to be possession  by the secured  party,  or possession by a purchaser or
a person  designated  by such secured  party,  for purposes of  perfecting  the security  interest  pursuant to the
Minnesota  Uniform  Commercial  Code  and  the  Uniform  Commercial  Code  of  any  other  applicable  jurisdiction
(including,  without  limitation,  Sections  8-106,  9-313 and 9-106  thereof);  and  (d) notifications  to persons
holding such property,  and  acknowledgments,  receipts or confirmations from persons holding such property,  shall
be deemed notifications to, or acknowledgments receipts or confirmations from, securities  intermediaries,  bailees
or agents of, or persons  holding for (as  applicable)  the Trustee for the  purpose of  perfecting  such  security
interest under  applicable  law. RFC shall,  to the extent  consistent  with this  Agreement,  take such reasonable
actions as may be necessary to ensure that, if this  Agreement  were  determined  to create a security  interest in
the Mortgage  Loans and the other  property  described  above,  such security  interest would be determined to be a
perfected  security  interest of first priority under  applicable law and will be maintained as such throughout the
term of this  Agreement.  Without  limiting the generality of the  foregoing,  RFC shall prepare and deliver to the
Company not less than 15 days prior to any filing  date,  and the Company  shall file,  or shall cause to be filed,
at the expense of RFC, all filings  necessary  to maintain the  effectiveness  of any  original  filings  necessary
under the Uniform  Commercial Code as in effect in any jurisdiction to perfect the Company's  security  interest in
or lien on the Mortgage  Loans,  including  without  limitation  (x) continuation  statements,  and (y) such  other
statements  as may be  occasioned by (1) any  change of name of RFC or the Company,  (2) any  change of location of
the place of business  or the chief  executive  office of RFC or,  (3) any  transfer of any  interest of RFC in any
Mortgage Loan.

         Notwithstanding  the foregoing,  (i) the Master  Servicer  shall retain all servicing  rights  (including,
without  limitation,  primary servicing and master servicing) relating to or arising out of the Mortgage Loans, and
all rights to receive  servicing fees,  servicing income and other payments made as compensation for such servicing
granted to it under the Pooling and  Servicing  Agreement  pursuant to the terms and  conditions  set forth therein
(collectively,  the "Servicing  Rights") and (ii) the  Servicing Rights are not included in the collateral in which
RFC grants a security interest pursuant to the immediately preceding paragraph.

Section 3.          Concurrently  with the  execution  and  delivery  hereof,  the  Company  hereby  assigns to RFC
without  recourse all of its right,  title and interest in and to the Class A-P and Class A-V Certificates and a de

(vii)    There is no delinquent tax or assessment lien against any Mortgaged Property;

(xi)     Each  Mortgaged  Property  is free of damage  and in good  repair and no notice of  condemnation  has been

state and federal laws, including, but not limited to, all applicable anti-predatory lending laws;

completion  of such  improvements)  have been  complied  with.  All costs,  fees and  expenses  incurred in making,

designation if the law imposes greater  restrictions or additional  legal liability for residential  mortgage loans
with high interest rates, points and/or fees;

         Upon  discovery  by RFC or upon  notice  from the  Company  or the  Trustee  of a breach of the  foregoing
representations  and  warranties  in respect of any  Mortgage  Loan which  materially  and  adversely  affects  the
interests of any holders of the  Certificates  or of the Company in such Mortgage Loan or upon the  occurrence of a
Repurchase  Event  (hereinafter  defined),  notice of which breach or  occurrence  shall be given to the Company by

that gave rise to the  obligation  to  repurchase  or substitute a Mortgage Loan pursuant to this Section 4 was the
representation  set forth in clause  (xii) or  (xxxviii)  of this  Section 4, then RFC shall pay to the Trust Fund,
concurrently  with and in addition to the  remedies  provided in the  preceding  sentence,  an amount  equal to any
liability,  penalty or expense that was actually  incurred and paid out of or on behalf of the Trust Fund, and that
directly  resulted from such breach,  or if incurred and paid by the Trust Fund thereafter,  concurrently with such
payment.

APPENDIX E - STANDARD & POOR'S PREDATORY LENDING CATEGORIES

Standard & Poor's has categorized loans governed by anti-predatory lending laws in the Jurisdictions listed below
into three categories based upon a combination of factors that include (a) the risk exposure associated with the
assignee liability and (b) the tests and thresholds set forth in those laws. Note that certain loans classified
by the relevant statute as Covered are included in Standard & Poor's High Cost Loan Category because they
included thresholds and tests that are typical of what is generally considered High Cost by the industry.

                                                                                             REVISED April 18, 2006
