        RFC and the  Company  agree  that the sale of each  Pledged  Asset  Loan

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. Nonetheless,  (a) this Agreement is intended to be and hereby
is 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 and (ii) with respect to each Mortgage Loan other
than a Cooperative 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 state of  formation,  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.
               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 a de minimis  portion of the Class R-I,  Class R-II and Class
R-III  Certificates as part of the  consideration  payable to RFC by the Company
pursuant to this Agreement.

respecting which such information is furnished;
               (b) Each Mortgage Loan with a Loan-to-Value  Ratio at origination
in excess of 80% will be insured by a Primary Insurance Policy covering at least

knowledge,  each such Primary  Insurance  Policy is in full force and effect and
the Trustee is entitled to the benefits thereunder;
               (c) Each Primary  Insurance  Policy insures the named insured and
its successors and assigns, and the issuer of the Primary Insurance Policy is an
insurance  company whose  claims-paying  ability is currently  acceptable to the

               (d) Immediately  prior to the assignment of the Mortgage Loans to
the  Company,  RFC had good title to, and was the sole owner of,  each  Mortgage
Loan free and clear of any pledge, lien, encumbrance or security interest (other
than rights to servicing and related  compensation  and, with respect to certain
Mortgage  Loans,  the monthly  payment due on the first Due Date  following  the
Cut-off  Date),  and no action  has been taken or failed to be taken by RFC that

               (f) Subject to clause (e) above as respects delinquencies,  there
is no default,  breach,  violation or event of  acceleration  existing under any
Mortgage Note or Mortgage and no event which,  with notice and expiration of any
grace or cure period, would constitute a default,  breach, violation or event of
acceleration,  and no such default,  breach,  violation or event of acceleration
has been waived by the Seller or by any other entity  involved in originating or
servicing a Mortgage Loan;
               (g) There is no  delinquent  tax or  assessment  lien against any
Mortgaged Property;
               (h) No Mortgagor has any right of offset, defense or counterclaim

clause (aa) below;
               (j) Each Mortgaged  Property is free of damage and in good repair
and no notice of condemnation  has been given with respect thereto and RFC knows
of nothing involving any Mortgaged Property that could reasonably be expected to

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

which  render the rights and  remedies  of the holder  adequate  to realize  the
benefits of the security  against the Mortgaged  Property,  including (i) in the

foreclosure,   if  available  under  applicable  law,  and  (iii)  otherwise  by

right to foreclosure,  subject in each case to applicable federal and state laws
and judicial precedents with respect to bankruptcy and right of redemption;
               (m) With  respect  to each  Mortgage  that is a deed of trust,  a
trustee duly qualified under  applicable law to serve as such is properly named,
designated  and serving,  and except in connection  with a trustee's  sale after

lien  mortgage  loans,  with a negative  amortization  feature  having  terms to
maturity of not more than 40 years from the date of origination or  modification
with monthly  payments due, with respect to a majority of the Mortgage Loans, on

leasehold estates is readily  marketable;  the lease is recorded and no party is
in any way in breach of any  provision of such lease;  the  leasehold is in full
force and effect and is not  subject to any prior lien or  encumbrance  by which
the leasehold  could be terminated or subject to any charge or penalty;  and the
remaining  term of the lease does not  terminate  less than ten years  after the
maturity date of such Mortgage Loan;
               (p) Each Assigned Contract relating to each Pledged Asset Loan is
a valid,  binding and legally  enforceable  obligation  of the parties  thereto,
enforceable  in accordance  with their terms,  except as limited by  bankruptcy,
insolvency  or  other  similar  laws  affecting  generally  the  enforcement  of
creditor's rights;

interest  as owner of each  Pledged  Asset  Loan in and to each of the  Assigned

Person;

confirmed  the transfer to the  Trustee,  as assignee of the  Depositor,  of the
Mortgage on the MERS(R) System;
               (t) No  instrument  of  release or waiver  has been  executed  in
connection with the Mortgage Loans, and no Mortgagor has been released, in whole
or in part from its obligations in connection with a Mortgage Loan;
               (u) With respect to each Mortgage  Loan,  either (i) the Mortgage
Loan is  assumable  pursuant  to the  terms of the  Mortgage  Note,  or (ii) the

liabilities;
               (oo) The methodology used in underwriting the extension of credit
for each Group I Loan did not rely on the extent of the borrower's equity in the
collateral as the principal  determining  factor in approving  such extension of
credit. The methodology  employed objective criteria that related such facts as,
without limitation, the borrower's credit history, income, assets or liabilities
to the proposed  mortgage payment and, based on such  methodology,  the Mortgage
Loan's  originator  made  a  reasonable   determination  that  at  the  time  of
origination the borrower had the ability to make timely payments on the Mortgage
Loan;
               (pp) No  borrower  under a Group I Loan was  charged  "points and
fees" in an amount greater than (a) $1,000 or (b) 5% of the principal  amount of
such Group I Loan,  whichever is greater.  For purposes of this  representation,
"points and fees" (x) include  origination,  underwriting,  broker and  finder's
fees and charges  that the lender  imposed as a condition  of making the Group I
Loan, whether they are paid to the lender or a third party; and (y) exclude bona
fide discount points,  fees paid for actual services rendered in connection with
the origination of the mortgage (such as attorneys' fees, notaries fees and fees
paid for property appraisals,  credit reports,  surveys,  title examinations and
extracts,  flood  and tax  certifications,  and home  inspections);  the cost of
mortgage insurance or credit-risk price adjustments; the costs of title, hazard,
and flood  insurance  policies;  state and local transfer taxes or fees;  escrow
deposits  for the future  payment  of taxes and  insurance  premiums;  and other
miscellaneous fees and charges that, in total, do not exceed 0.25 percent of the
loan amount;
               (qq)  No  Group  I  Loan  was  originated  in  connection  with a
manufactured housing unit;
               (rr) No Group I Loan was originated more than one year before the
date of issuance of the Certificates.
               RFC shall provide written notice to GMAC Mortgage  Corporation of
the sale of each Pledged Asset Loan to the Company  hereunder and by the Company
to the Trustee under the Pooling and Servicing Agreement, and shall maintain the
Schedule of Additional  Owner  Mortgage  Loans (as defined in the Credit Support
Pledge  Agreement),  showing  the Trustee as the  Additional  Owner of each such
Pledged  Asset Loan,  all in accordance  with Section 7.1 of the Credit  Support
Pledge Agreement.
        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 RFC, if it discovers  the same,
RFC shall,  within 90 days  after the  earlier  of its  discovery  or receipt of
notice  thereof,  either cure such breach or  Repurchase  Event in all  material
respects or,  either (i)  purchase  such  Mortgage  Loan from the Trustee or the
Company,  as the case may be, at a price  equal to the  Purchase  Price for such
Mortgage Loan or (ii) substitute a Qualified  Substitute  Mortgage Loan or Loans
for such Mortgage Loan in the manner and subject to the limitations set forth in
Section  2.04  of the  Pooling  and  Servicing  Agreement.  Notwithstanding  the
foregoing,  it is  understood  by  the  parties  hereto  that  a  breach  of the
representations  and warranties made in any of clause (bb), (cc), (dd), (ee) and
(gg)  through  (rr) of this  Section 4 with  respect to any Group I Loan will be
deemed to materially  and  adversely  affect the interests of the Holders of the
Certificates in the related Mortgage Loan. If the breach of  representation  and
warranty that gave rise to the obligation to repurchase or substitute a Mortgage
Loan pursuant to this Section 4 was the representation and warranty set forth in
clause (k) 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.
               5. With respect to each  Mortgage  Loan, a first lien  repurchase
event  ("Repurchase  Event") shall have occurred if it is discovered that, as of
the date thereof, the related Mortgage was not a valid first lien on the related
Mortgaged  Property  subject  only to (i) the lien of real  property  taxes  and
assessments  not  yet  due  and  payable,   (ii)  covenants,   conditions,   and
restrictions,  rights of way, easements and other matters of public record as of
the date of recording of such Mortgage and such permissible  title exceptions as
are listed in the Program Guide and (iii) other matters to which like properties
are commonly subject which do not materially  adversely  affect the value,  use,
enjoyment or marketability of the Mortgaged Property. In addition,  with respect
to any  Mortgage  Loan as to which the  Company  delivers  to the Trustee or the
Custodian an affidavit  certifying that the original Mortgage Note has been lost
or  destroyed,  if  such  Mortgage  Loan  subsequently  is in  default  and  the
enforcement thereof or of the related Mortgage is materially  adversely affected
by the absence of the original Mortgage Note, a Repurchase Event shall be deemed
to have occurred and RFC will be obligated to repurchase or substitute  for such
Mortgage Loan in the manner set forth in Section 4 above.
               6. This  Agreement  shall  inure to the benefit of and be binding
upon the parties  hereto and their  respective  successors  and assigns,  and no
other person shall have any right or obligation hereunder.
               IN WITNESS WHEREOF, the parties have entered into this Assignment
and Assumption Agreement on the date first written above.

▇▇▇▇▇▇▇▇  ▇ - 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.
