         Section 2.1       Sale of Mortgage Loans.

                  (a) WG Trust 2003,  by the execution and delivery of this  Agreement,  does hereby sell,  assign,

                  (b) In  connection  with the  conveyance  by  WG Trust  2003 of the  Mortgage  Loans,  the Seller

all of the Mortgage  Loans sold by the Seller  specifying  for each Mortgage  Loan (i) its account  number and (ii)
its Cut-Off Date Principal  Balance.  The Mortgage Loan Schedule  indicating such  information  with respect to the
Mortgage  Loans shall be marked as Exhibit 1 to this Agreement and is hereby  incorporated  into and made a part of
this Agreement.

                  (c) In connection  with the conveyance by WG Trust 2003 of the Mortgage Loans,  GMACM shall,  (A)
with respect to each  Mortgage  Loan,  on behalf of the Purchaser  deliver to, and deposit with the  Custodian,  at
least five (5) Business Days before the Closing  Date,  the original  Mortgage  Note  endorsed or assigned  without
recourse in blank (which  endorsement  shall contain  either an original  signature or a facsimile  signature of an
authorized  officer of GMACM),  or, with respect to any Mortgage  Loan as to which the original  Mortgage  Note has
been  permanently  lost or  destroyed  and has not been  replaced,  a Lost  Note  Affidavit,  and any  modification
agreement  or  amendment  to such  Mortgage  Note and (B)  except as  provided  in clause  (A) with  respect to the
Mortgage Notes, deliver the Mortgage Files to the Servicer.

         Within the time  period for the review of each  Mortgage  Note set forth in Section  2.2 of the  Custodial
Agreement,  if a material defect in any Mortgage Note is discovered  which may materially and adversely  affect the
value of the related  Mortgage Loan, or the interests of the Indenture  Trustee (as pledgee of the Mortgage Loans),
the Noteholders,  the  Certificateholders  in such Mortgage Loan, including GMACM's failure to deliver the Mortgage
Note to the  Custodian on behalf of the Indenture  Trustee,  GMACM shall cure such defect,  repurchase  the related
Mortgage Loan at the Repurchase  Price or substitute an Eligible  Substitute  Loan therefor upon the same terms and
conditions  set forth in Section 3.1 hereof for  breaches of  representations  and  warranties  as to the  Mortgage
Loans,  provided that the Seller shall have the option to substitute an Eligible  Substitute Loan or Loans for such
Mortgage Loan only if such  substitution  occurs within two years  following the Closing Date. If a material defect
in any of the  documents  in the  Mortgage  File  held by the  Servicer  is  discovered  which may  materially  and

the Mortgage Loans), the Noteholders,  the  Certificateholders  in such Mortgage Loan, including GMACM's failure to
deliver  such  documents  to the  Servicer  on behalf of the  Indenture  Trustee,  GMACM  shall  cure such  defect,
repurchase the related  Mortgage Loan at the Repurchase  Price or substitute an Eligible  Substitute  Loan therefor
upon the same terms and conditions set forth in Section 3.1 hereof for breaches of  representations  and warranties
as to the Mortgage  Loans,  provided  that the Seller shall have the option to  substitute  an Eligible  Substitute
Loan or Loans for such Mortgage Loan only if such substitution occurs within two years following the Closing Date.

         Upon sale of the Mortgage  Loans,  the  ownership of each  Mortgage  Note,  each related  Mortgage and the
contents  of the  related  Mortgage  File shall be vested in the  Purchaser  and the  ownership  of all records and
documents  with respect to the Mortgage  Loans that are prepared by or that come into the  possession of the Seller
or by the Servicer under the Servicing  Agreement shall  immediately  vest in the Purchaser,  and shall be promptly
delivered to the Servicer and retained  and  maintained  in trust by 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.  The
Seller's records will accurately reflect the sale of each Mortgage 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.

                  (d) The parties  hereto intend that the  transactions  set forth herein  constitute a sale by the
Seller to the  Purchaser  of each of the Seller'  right,  title and  interest in and to their  respective  Mortgage
Loans and other  property as and to the extent  described  above.  In the event the  transactions  set forth herein
are deemed not to be a sale,  the Seller hereby grants to the Purchaser a security  interest in all of the Seller's

shall and hereby does  constitute a security  agreement  under  applicable  law. The Seller agrees to take or cause
to be taken such actions and to execute such documents,  including the filing of any  continuation  statements with
respect  to the UCC-1  financing  statements  filed with  respect to the  Mortgage  Loans by the  Purchaser  on the
Closing Date, and any  amendments  thereto  required to reflect a change in the name or corporate  structure of the
Seller or the filing of any additional  UCC-1  financing  statements  due to the change in the principal  office or
jurisdiction  of  incorporation  of the Seller,  as are  necessary to perfect and protect the  Purchaser's  and its
assignees'  interests  in  each  Mortgage  Loan  and the  proceeds  thereof.  The  Servicer  shall  file  any  such
continuation statements on a timely basis.

                  (e) In  connection  with the  assignment  of any Mortgage  Loan  registered  on the MERS® System,
GMACM further agrees that it will cause,  at GMACM's own expense,  as soon as  practicable  after the Closing Date,
the MERS®  System to  indicate  that such  Mortgage  Loan has 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 Mortgage 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 Mortgage Loan and (b)
the series  specific code in the field "Pool Field" which  identifies  the series of the Notes issued in connection
with the Mortgage  Loans.  GMACM agrees that it will not alter the codes  referenced in this paragraph with respect
to any Mortgage  Loan during the term of this  Agreement  unless and until such  Mortgage  Loan is  repurchased  in
accordance with the terms of this Agreement.

Issuer, the Owner Trustee,  the Indenture Trustee or the Custodian,  as applicable,  of a breach of the Seller's or
GMACM's  respective  representations  or warranties in paragraphs (a) or (d)(I) above that materially and adversely
affects the  interests  of the  Securityholders,  in any Mortgage  Loan,  the Seller  shall,  within 90 days of its
discovery  or its receipt of 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 Mortgage  Loan or a Related  Document,  either (A)  repurchase
such Mortgage Loan from the Issuer at the  Repurchase  Price,  or (B)  substitute  one or more Eligible  Substitute
Loans for such Mortgage Loan, in each case in the manner and subject to the conditions  and  limitations  set forth
below.

         Upon  discovery  by the  Seller or the  Servicer  or upon  notice  from the  Purchaser,  the  Issuer,  the
Servicer,  the Owner Trustee,  the Indenture Trustee or the Custodian,  as applicable,  of a breach of the Seller's
or GMACM's  representations  or  warranties in paragraphs  (b) or (d)(II)  above  (including,  for the avoidance of
doubt,  material damage to the physical property caused by the wildfires in Southern  California in connection with
paragraph  (b)(xviii)  above),  with respect to any Mortgage  Loan, or upon the  occurrence of a Repurchase  Event,
that materially and adversely affects the interests of the  Securityholders  or the Purchaser in such Mortgage Loan
(notice  of which  shall be given to the  Purchaser  by the  Seller or the  Servicer,  if it  discovers  the same),
notwithstanding  the  Seller's or GMACM's lack of knowledge  with respect to the  substance of such  representation
and  warranty,  GMACM or the Seller  shall,  as  applicable,  within 90 days after the earlier of its  discovery or
receipt of notice  thereof,  or, if such breach has the effect of making the Mortgage  Loan fail to be a "qualified
mortgage"  within the meaning of Section  860G of the Internal  Revenue  Code,  within 90 days after the  discovery
thereof by either the Seller, the Servicer,  the Issuer, the Owner Trustee,  the Indenture Trustee or the Purchaser
either cure such breach or Repurchase  Event in all material  respects or either (i) repurchase  such Mortgage Loan
from the  Issuer at the  Repurchase  Price,  or (ii)  substitute  one or more  Eligible  Substitute  Loans for such
Mortgage Loan, in each case in the manner and subject to the  conditions set forth below,  provided that the Seller
shall have the option to  substitute  an  Eligible  Substitute  Loan or Loans for such  Mortgage  Loan only if such
substitution  occurs within two years  following the Closing Date. The Repurchase  Price for any such Mortgage Loan
repurchased  by the  Seller  shall be  deposited  or caused to be  deposited  by the  Servicer  into the  Custodial
Account.  Any purchase of a Mortgage Loan due to a Repurchase Event shall be the obligation of the Seller.

         In furtherance  of the foregoing,  if the Seller is not a member of MERS and the Mortgage is registered on
the MERS®  System,  the Seller,  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 the
Seller and shall cause such Mortgage to be removed from  registration  on the MERS® System in accordance with MERS'
rules and regulations.

         In the event that the Seller  elects to  substitute  an  Eligible  Substitute  Loan or Loans for a Deleted
Loan  pursuant to this  Section  3.1,  the Seller  shall  deliver to the  Custodian  on behalf of the Issuer,  with
respect to such Eligible  Substitute Loan or Loans, the original  Mortgage Note, with the 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 the
Seller on the next  succeeding  Payment  Date,  provided  that a payment at least 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  the 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 Mortgage
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  Mortgage  Loan  Schedule to the Owner  Trustee,  the  Indenture
Trustee.  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,   the  Seller  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  (viii)  (xiii),  (xxiv),  (xxv)(B),  (xxvi) and (xxvii)  thereof and other than clauses
(iii) and (ix) thereof in the case of Eligible  Substitute  Loans  substituted by WG Trust 2003);  the Seller shall
be deemed to have made the  representations  and  warranties  set forth in  Section  3.1(d)(II);  as of the date of
substitution,  and the Seller shall be deemed to have made a  representation  and warranty  that each Mortgage Loan
so substituted is an Eligible  Substitute  Loan as of the date of  substitution.  In addition,  the Seller 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).  The Seller shall  deposit the amount of such  shortfall  into the
Custodial Account on the date of substitution, without any reimbursement therefor.

         Notwithstanding  the  foregoing,  with  respect  to any  Mortgage  Loan  for  which a  breach  of  Section
3.1(b)(xv)  has  occurred,  no  substitutions  will be allowed  unless the Seller pays to the  Servicer,  an amount
sufficient  to indemnify  the Trust Fund,  Purchaser,  Issuer 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 of 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 the
Seller the related  Mortgage  Note for the Mortgage  Loan being  repurchased  or  substituted  for,  (ii) cause the
Servicer  to release to the 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,  as shall be necessary to vest in
the Seller or its respective  designee such Mortgage Loan released  pursuant  hereto and  thereafter  such Mortgage
Loan shall not be an asset of the Issuer.

         It is  understood  and agreed that the  obligation  of the Seller to cure any breach,  or to repurchase or
substitute  for any Mortgage 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 the Seller.

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

         In the event that WG Trust does not comply with its  obligations to repurchase  mortgage loans pursuant to

against all claims of third parties claiming through or under the Seller;  provided,  however, that nothing in this
Section  4.1  shall be  deemed to apply to any Liens for  municipal  or other  local  taxes and other  governmental
charges if such  taxes or  governmental  charges  shall not at the time be due and  payable or if the Seller  shall
currently be contesting the validity thereof in good faith by appropriate Proceedings.

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 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  parties  hereto  that  the
Purchaser  will be  purchasing  on the  Closing  Date,  and the Seller  will be selling on the  Closing  Date,  the
Mortgage  Loans,  rather than the  Purchaser  providing a loan to the Seller  secured by the Mortgage  Loans on the
Closing  Date.  Accordingly,  the  parties  hereto  each intend to treat this  transaction  for federal  income tax
purposes as a sale by the Seller,  and a purchase by the  Purchaser,  of the  Mortgage  Loans on the Closing  Date.
The  Purchaser and the Issuer shall each have the right to review the Mortgage  Loans and the Related  Documents to
determine  the  characteristics  of the Mortgage  Loans which will affect the federal  income tax  consequences  of
owning the Mortgage  Loans,  and the 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 the Seller under this Agreement
cannot be assigned or delegated to a third party  without the consent of the  Purchaser,  which consent shall be at
the Purchaser's sole discretion;  provided,  that the Seller may assign its obligations  hereunder to any Affiliate
of the Seller,  to any Person  succeeding  to the  business  of the Seller,  to any Person into which the Seller is
merged and to any Person  resulting from any merger,  conversion or  consolidation  to which the Seller is a party.
The parties hereto  acknowledge  that the Purchaser is acquiring the Mortgage Loans for the purpose of contributing
them to the GMACM Home Equity Loan Trust 2007-HE3.

                  (b) As an inducement to the Purchaser and the Issuer to purchase the Mortgage  Loans,  the Seller
acknowledges  and consents to (i) the  assignment by the Purchaser to the Issuer of all of the  Purchaser's  rights
against the Seller  pursuant to this Agreement  insofar as such rights relate to the Mortgage Loans  transferred to
the  Issuer  and to the  enforcement  or  exercise  of any right or remedy  against  the  Seller  pursuant  to this
Agreement by the Issuer,  (ii) the  enforcement or exercise of any right or remedy  against the 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 the Seller
following  an Event of Default  under the  Indenture.  Such  enforcement  of a right or remedy by the  Issuer,  the
Owner  Trustee 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 the  Seller  and  the
provisions of Article VI hereof shall survive the purchase of the Mortgage Loans hereunder.

         IN WITNESS  WHEREOF,  the  parties  hereto  have caused  their  names to be signed to this  Mortgage  Loan
Purchase  Agreement by their  respective  officers  thereunto  duly  authorized  as of the day and year first above
written.
