or by GMACM in its capacity as Servicer under the Servicing  Agreement shall  immediately vest

documents  in  possession  of WG Trust and retained  and  maintained  in trust by GMACM as the
Servicer  (except for the Mortgage  Notes,  which shall be retained by the  Custodian)  at the
will  of  the  Purchaser,  in  such  custodial  capacity  only.  Each  Seller's  records  will
accurately reflect the sale of each Home Loan sold by it to the Purchaser.

        The Purchaser hereby  acknowledges its acceptance of all right,  title and interest to
the property conveyed to it pursuant to this Section 2.1.

(f)     The parties hereto intend that the transactions set forth herein  constitute a sale by
the Sellers to the  Purchaser  of each of the  Sellers'  right,  title and  interest in and to

event the  transactions  set forth  herein  are deemed not to be a sale,  each  Seller  hereby

interest  in,  to and  under  all  accounts,  chattel  papers,  general  intangibles,  payment
intangibles,   contract  rights,  certificates  of  deposit,  deposit  accounts,  instruments,
documents,  letters of credit, money, advices of credit,  investment property, goods and other
property  consisting of,  arising under or related to the Home Loans and such other  property,

does  constitute a security  agreement  under  applicable  law.  Each Seller agrees to take or
cause to be taken such actions and to execute such  documents,  including  without  limitation
the filing of any  continuation  statements  with  respect to the UCC-1  financing  statements
filed  with  respect  to the  Home  Loans  by the  Purchaser  on the  Closing  Date,  and  any
amendments  thereto  required to reflect a change in the name or  corporate  structure of such
Seller or the filing of any  additional  UCC-1  financing  statements due to the change in the
principal  office or  jurisdiction  of  incorporation  of such  Seller,  as are  necessary  to
perfect and protect the  Purchaser's  and its  assignees'  interests in each Home Loan and the
proceeds  thereof.  The  Servicer  shall  file any such  continuation  statements  on a timely
basis.

(g)     In connection  with the  assignment  of any Home Loan  registered on the MERS(R)System,
GMACM  further  agrees that it will  cause,  at GMACM's own  expense,  as soon as  practicable
after the Closing  Date,  the MERS(R)System to indicate that such Home Loans have been assigned
by GMACM to the Indenture  Trustee in accordance  with this  Agreement or the Trust  Agreement
for the  benefit of the  Noteholders  by  including  (or  deleting,  in the case of Home Loans
which are  repurchased  in accordance  with this  Agreement)  in such  computer  files (a) the
specific code which  identifies  the  Indenture  Trustee as the assignee of such Home Loan and

as  applicable,  of a  breach  of such  Seller's  or  GMACM's  respective  representations  or
warranties  in  paragraphs (a)  or  (c)  above  that  materially  and  adversely  affects  the
interests of the  Securityholders  or the Credit  Enhancer,  as applicable,  in any Home Loan,

notice of such breach,  either  (i) cure  such breach in all material  respects or (ii) to the
extent  that  such  breach  is with  respect  to a Home  Loan or a  Related  Document,  either
(A) repurchase  such Home Loan from the Issuer at the Repurchase Price, or (B) substitute  one
or more Eligible  Substitute  Loans for such Home Loan, in each case in the manner and subject
to the conditions and limitations set forth below.

        Upon  discovery  by either  Seller or GMACM or upon  notice  from the  Purchaser,  the
Credit  Enhancer,  the  Issuer,  GMACM,  the  Owner  Trustee,  the  Indenture  Trustee  or the
Custodian,  as applicable,  of a breach of a Seller's or GMACM's representations or warranties
in paragraphs  (b) or (d) above,  with respect to any Home Loan,  or upon the  occurrence of a
Repurchase   Event,   that   materially   and   adversely   affects  the   interests   of  the
Securityholders,  the Credit  Enhancer  or the  Purchaser  in such Home Loan  (notice of which
shall be given to the  Purchaser  by the  respective  Seller or  GMACM,  if it  discovers  the
same),  notwithstanding  such  Seller's  or  GMACM's  lack of  knowledge  with  respect to the
substance  of such  representation  and  warranty,  such Seller or GMACM,  as the case may be,
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)
repurchase  such Home Loan from the Issuer at the Repurchase  Price, or (ii) substitute one or
more Eligible  Substitute  Loans for such Home Loan, in each case in the manner and subject to
the conditions set forth below.  The  Repurchase  Price for any such Home Loan  repurchased by
such Seller or GMACM shall be deposited  or caused to be  deposited  by the Servicer  into the
Custodial  Account.  Any  purchase  of a Home  Loan  due to a  Repurchase  Event  shall be the
obligation of GMACM.

        In  furtherance  of  the  foregoing,  if  GMACM  or the  Seller  that  repurchases  or
substitutes  a Home Loan is not a member of MERS and the Mortgage is  registered  on the MERS(R)
System,  GMACM,  at its own expense and without any right of  reimbursement,  shall cause MERS
to execute and  deliver an  assignment  of the  Mortgage in  recordable  form to transfer  the
Mortgage  from MERS to GMACM or the Seller and shall cause such  Mortgage  to be removed  from
registration on the MERS(R)System in accordance with MERS' rules and regulations.

        In the event that either Seller elects to  substitute an Eligible  Substitute  Loan or
Loans for a Deleted  Loan  pursuant to this  Section  3.1,  such Seller  shall  deliver to the
Custodian on behalf of the Issuer,  with respect to such  Eligible  Substitute  Loan or Loans,
the original  Mortgage Note endorsed as required under the  definition of "Mortgage  File" and
shall  deliver the other  documents  required to be part of the Mortgage File to the Servicer.
No  substitution  will be made in any  calendar  month after the  Determination  Date for such
month.  Monthly  Payments  due with  respect  to  Eligible  Substitute  Loans in the  month of
substitution  shall not be part of the Trust  Estate and will be retained by the  Servicer and
remitted by the Servicer to such Seller on the next succeeding  Payment Date,  provided that a
payment  equal to the  applicable  Monthly  Payment  for such month in respect of the  Deleted
Loan has been  received by the Issuer.  For the month of  substitution,  distributions  to the
Note Payment  Account  pursuant to the Servicing  Agreement  will include the Monthly  Payment
due on a Deleted  Loan for such month and  thereafter  such Seller shall be entitled to retain
all amounts  received in respect of such Deleted  Loan.  The Servicer  shall amend or cause to
be  amended  the Home Loan  Schedule  to reflect  the  removal  of such  Deleted  Loan and the
substitution  of the  Eligible  Substitute  Loan or Loans and the Servicer  shall  deliver the
amended  Home Loan  Schedule  to the Owner  Trustee,  the  Indenture  Trustee  and the  Credit
Enhancer.  Upon such substitution,  the Eligible  Substitute Loan or Loans shall be subject to
the terms of this  Agreement  and the  Servicing  Agreement  in all  respects,  GMACM shall be
deemed  to  have  made  the  representations  and  warranties  with  respect  to the  Eligible
Substitute  Loan  contained  herein set forth in Section  3.1(b)  (other than clauses  (xiii),
(xiv), (xxi),  (xxiv),  (xxv)(B),  (xxvi),  (xxvii) and (xxxii) thereof and other than clauses
(iii) and (ix)  thereof in the case of Eligible  Substitute  Loans  substituted  by WG Trust),
and,  if the  Seller is WG Trust,  WG Trust  shall be deemed to have made the  representations
and  warranties  set forth in  Section 3.1(d),  in each case, as of the date of  substitution,
and the related  Seller shall be deemed to have made a  representation  and warranty that each
Home Loan so substituted is an Eligible  Substitute  Loan as of the date of  substitution.  In
addition,  GMACM shall be obligated to repurchase or  substitute  for any Eligible  Substitute
Loan as to which a Repurchase  Event has occurred as provided  herein.  In connection with the
substitution  of one or more  Eligible  Substitute  Loans for one or more Deleted  Loans,  the
Servicer shall determine the amount (such amount,  a  "Substitution  Adjustment  Amount"),  if
any, by which the  aggregate  principal  balance of all such Eligible  Substitute  Loans as of
the date of  substitution  is less than the  aggregate  principal  balance of all such Deleted
Loans (after  application  of the principal  portion of the Monthly  Payments due in the month
of  substitution  that are to be  distributed  to the Note  Payment  Account  in the  month of
substitution).  Such Seller  shall  deposit the amount of such  shortfall  into the  Custodial
Account on the date of  substitution,  without  any  reimbursement  therefor.  Notwithstanding
the  forgoing,  with  respect  to any Home Loan for which a breach of  Section 3.1(b)(xv)  has
occurred,  no substitutions will be allowed unless GMACM or WG Trust pays to the Servicer,  an
amount  sufficient to indemnify the Trust Fund,  Purchaser,  Issuing  Entity,  Credit Enhancer
and Indenture Trustee against any losses, damages, penalties,  fines, forfeitures,  reasonable
and  necessary  legal  fees and  related  costs,  judgments,  and  other  costs  and  expenses
resulting  from any  claim,  demand,  defense  or  assertion  based on or  grounded  upon,  or
resulting from, a breach such representation.

        Upon  receipt by the  Indenture  Trustee on behalf of the Issuer and the  Custodian of
written  notification,  signed by a Servicing Officer, of the deposit of such Repurchase Price
or of such  substitution of an Eligible  Substitute  Loan (together with the complete  related
Mortgage  File) and  deposit of any  applicable  Substitution  Adjustment  Amount as  provided
above,  the Custodian,  on behalf of the Indenture  Trustee,  shall (i) release to such Seller
or GMACM,  as the case may be, the related  Mortgage Note for the Home Loan being  repurchased
or  substituted  for,  (ii)  cause the  Servicer  to  release  to such  Seller  any  remaining
documents  in the  related  Mortgage  File  which  are held by the  Servicer,  and  (iii)  the
Indenture  Trustee on behalf of the Issuer  shall  execute and  deliver  such  instruments  of
transfer  or   assignment   prepared  by  the  Servicer,   in  each  case  without   recourse,
representation  or warranty  as shall be  necessary  to vest in such  Seller or GMACM,  as the
case  may be,  or its  respective  designee  such  Home  Loan  released  pursuant  hereto  and
thereafter such Home Loan shall not be an asset of the Issuer.

        It is understood  and agreed that the  obligation of each Seller and GMACM to cure any
breach,  or to  repurchase  or  substitute  for any Home  Loan as to which  such a breach  has
occurred  and  is  continuing,  shall  constitute  the  sole  remedy  respecting  such  breach
available  to the  Purchaser,  the Issuer,  the  Certificateholders  (or the Owner  Trustee on
behalf of the  Certificateholders)  and the Noteholders (or the Indenture Trustee on behalf of
the Noteholders) against such Seller and GMACM.

        It is understood and agreed that the  representations and warranties set forth in this
Section 3.1 shall  survive  delivery  of the  respective  Mortgage  Files to the Issuer or the
Custodian.

or, with respect to any of the foregoing Persons, at such other address as may hereafter be
furnished to the other foregoing Persons in writing.

Section 8.4    Severability  of Provisions.  If any one or more of the covenants,  agreements,
provisions or terms of this Agreement  shall be held invalid for any reason  whatsoever,  then
such covenants,  agreements,  provisions or terms shall be deemed severable from the remaining
covenants,  agreements,  provisions or terms of this  Agreement and shall in no way affect the
validity of enforceability of the other provisions of this Agreement.

Section 8.5    Relationship  of  Parties.   Nothing  herein   contained  shall  be  deemed  or
construed  to  create a  partnership  or joint  venture  among  the  parties  hereto,  and the
services  of the GMACM shall be rendered  as an  independent  contractor  and not as agent for
the Purchaser.

Section 8.6    Counterparts.  This  Agreement  may be executed in any number of  counterparts,
each of which,  when so  executed,  shall be deemed to be an original  and such  counterparts,
together, shall constitute one and the same agreement.

Section 8.7    Further  Agreements.  The  parties  hereto each agree to execute and deliver to
the other  such  additional  documents,  instruments  or  agreements  as may be  necessary  or
appropriate to effectuate the purposes of this Agreement.

Section 8.8    Intention  of  the  Parties.  It is  the  intention  of  the  Sellers  and  the
Purchaser  that the Purchaser  will be purchasing on the Closing Date, and the Sellers will be
selling on the Closing Date,  the Home Loans,  rather than the  Purchaser  providing a loan to
the Sellers  secured by the Home Loans on the Closing Date.  Accordingly,  the Sellers and the
Purchaser each intend to treat this  transaction  for federal income tax purposes as a sale by
the  Sellers,  and a purchase by the  Purchaser,  of the Home Loans on the Closing  Date.  The
Purchaser  and the Issuer  shall each have the right to review the Home Loans and the  Related
Documents to  determine  the  characteristics  of the Home Loans which will affect the federal
income tax  consequences  of owning the Home Loans,  and each Seller shall  cooperate with all
reasonable requests made by the Purchaser or the Issuer in the course of such review.

Section 8.9    Successors and Assigns; Assignment of this Agreement

(a)     This  Agreement  shall  bind and inure to the  benefit  of and be  enforceable  by the
parties  hereto and their  respective  permitted  successors and assigns.  The  obligations of
each Seller under this  Agreement  cannot be assigned or  delegated  to a third party  without
the  consent  of the  Credit  Enhancer  and  the  Purchaser,  which  consent  shall  be at the
Purchaser's sole discretion;  provided,  that each Seller may assign its obligations hereunder
to any Affiliate of such Seller,  to any Person  succeeding to the business of such Seller, to
any Person  into which such  Seller is merged  and to any Person  resulting  from any  merger,
conversion or consolidation  to which such Seller is a party.  The parties hereto  acknowledge
that the  Purchaser is acquiring  the Home Loans for the purpose of  contributing  them to the
GMACM Home Loan Trust 2006-HLTV1.

(b)     As  an  inducement  to  the  Purchaser  to  purchase  the  Home  Loans,   each  Seller
acknowledges  and consents to (i) the  assignment by the Purchaser to the Issuer of all of the
Purchaser's  rights  against  each Seller  pursuant to this  Agreement  insofar as such rights
relate to the Home Loans  transferred to the Issuer and to the  enforcement or exercise of any
right or remedy  against  either  Seller  pursuant to this  Agreement by the Issuer,  (ii) the
enforcement  or  exercise  of any right or  remedy  against  either  Seller  pursuant  to this
Agreement  by or on behalf of the Issuer and  (iii) the  Issuer's  pledge of its  interest  in
this Agreement to the Indenture  Trustee and the  enforcement by the Indenture  Trustee of any
such  right  or  remedy  against  either  Seller  following  an  Event of  Default  under  the
Indenture.  Such  enforcement  of a right or remedy by the  Issuer,  the  Owner  Trustee,  the
Credit  Enhancer  or the  Indenture  Trustee,  as  applicable,  shall  have the same force and
effect as if the right or remedy  had been  enforced  or  exercised  by the  Purchaser  or the
Issuer directly.

Section 8.10   Survival.  The  representations  and warranties  made herein by each Seller and
the provisions of Article VI hereof shall survive the purchase of the Home Loans hereunder.

Section 8.11   Third  Party   Beneficiary.   The  Credit  Enhancer  shall  be  a  third  party
beneficiary  hereof and shall be entitled to enforce the  provisions of this Agreement as if a
party hereto.
