        such assignment, Assignor or its designee will receive from the Assignee in immediately

        Trustee and, except with respect to any MERS Mortgage Loan,  delivered an assignment of
        mortgage in recordable form to the Trustee or its agent.

               5.     The  Assignor  warrants  and  represents  to, and  covenants  with,  the
Assignee that:

a.      Assignor is a limited  partnership  duly formed and validly existing under the laws of
the  State  of New  York  with  full  power  and  authority  to enter  into  and  perform  its
obligations under the Sale and Servicing Agreement and this Agreement;

b.      This  Agreement has been duly executed and  delivered by Assignor,  and,  assuming due
authorization,  execution  and delivery by each of the other  parties  hereto,  constitutes  a
legal,  valid and binding  agreement of Assignor,  enforceable  against it in accordance  with
its terms, subject to bankruptcy,  insolvency,  reorganization,  moratorium,  or other similar
laws affecting  creditors' rights generally and to general  principles of equity regardless of
whether enforcement is sought in a proceeding in equity or at law;

c.      The  execution,  delivery  and  performance  by  Assignor  of this  Agreement  and the
consummation of the  transactions  contemplated  hereby do not require the consent or approval
of,  the  giving of notice to, the  registration  with,  or the taking of any other  action in
respect of, any state, federal or other governmental  authority or agency,  except such as has
been obtained, given, effected or taken prior to the date thereof;

d.      The  execution  and  delivery  of this  Agreement  have  been duly  authorized  by all
necessary  corporate  action on the part of Assignor;  neither the  execution  and delivery by
Assignor of this  Agreement,  nor the  consummation  by Assignor  of the  transactions  herein
contemplated,  nor  compliance by Assignor with the provisions  hereof,  will conflict with or
result in a breach of, or constitute a default  under,  any of the provisions of the governing
documents of Assignor or any law,  governmental  rule or regulation or any material  judgment,
decree or order  binding on Assignor or any of its  properties,  or any of the  provisions  of
any  material  indenture,  mortgage,  deed of trust,  contract  or other  instrument  to which
Assignor is a party or by which it is bound;

e.      There are no actions,  suits or proceedings  pending or, to the knowledge of Assignor,
threatened,  before or by any court,  administrative  agency,  arbitrator or governmental body
(A)  with  respect  to any of the  transactions  contemplated  by this  Agreement  or (B) with
respect to any other matter that in the judgment of Assignor will be  determined  adversely to
Assignor  and will if  determined  adversely  to  Assignor  materially  adversely  affect  its
ability to perform its obligations under this Agreement;

f.      Immediately  prior to the assignment of the Mortgage  Loans to the Assignee,  Assignor
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 Assignor that would materially  adversely affect the  enforceability  of any Mortgage
Loan or the interests therein of the Assignee;

g.      The  Assignor  has not  received  notice of,  and has no  knowledge  of, any  offsets,
counterclaims  or other  defenses  available  to the Assignee  with  respect to the  Servicing
Agreement or the Mortgage Loans;

h.      Assignor has not waived or agreed to any waiver  under,  or agreed to any amendment or
other  modification  of, the Servicing  Agreement  (except for any amendments or modifications
with  respect  to the  Mortgage  Loans  set forth in the  Assignment,  as  applicable)  or the
Mortgage Loans,  including without limitation the transfer of the servicing  obligations under
the Servicing  Agreement.  Assignor has no knowledge  of, and has not received  notice of, any
waivers  under  or  amendments  or  other   modifications  of  or  assignments  of  rights  or
obligations under the Servicing Agreement or the Mortgage Loans;

i.      Neither  the  Assignor  nor  anyone  acting on its behalf  has  offered,  transferred,
pledged,  sold,  or otherwise  disposed of the Mortgage  Loans or any interest in the Mortgage
Loans to, or solicited any offer to buy or accept a transfer,  pledge or other  disposition of
the Mortgage  Loans or any interest in the Mortgage  Loans from,  or otherwise  approached  or
negotiated  with respect to the Mortgage  Loans,  any interest in the Mortgage Loans with, any
Person in any manner, or made any general  solicitation by means of general  advertising or in
any other  manner,  or taken any other action which would  constitute  a  distribution  of the
Mortgage Loans under the Securities Act of 1933 (the  "Securities  Act") or which would render
the  disposition  of the  Mortgage  Loans a violation  of Section 5 of the  Securities  Act or
require registration pursuant thereto;

j.      Each  Mortgaged  Property  is free of  damage  and in good  repair  and no  notice  of
condemnation  has been given with  respect to any  pending or  threatened  proceeding  for the
total or partial  condemnation  of the Mortgaged  Property,  and the Assignor knows of nothing
involving any Mortgaged  Property  that could  reasonably be expected to materially  adversely
affect the value or marketability of any Mortgaged Property;

k.      Except  for the  sale to the  Assignee,  Assignor  has not  assigned  or  pledged  any
Mortgage Note or the related Mortgage or any interest or participation therein;

l.      Assignor  has not  satisfied,  canceled,  or  subordinated  in whole  or in  part,  or
rescinded  the Mortgage,  and Assignor has not released the  Mortgaged  Property from the lien
of the  Mortgage,  in whole or in part,  nor has Assignor  executed an  instrument  that would
effect  any  such  release,  cancellation,  subordination,  or  rescission.  Assignor  has not
released  any  Mortgagor,  in  whole or in  part,  except  in  connection  with an  assumption
agreement  or other  agreement  approved by the related  federal  insurer,  to the extent such
approval was required; and

m.      None of the  Mortgage  Loans were 30 or more days  delinquent  in payment of principal
and interest as of as of January 1, 2007;

n.      Subject to clause (m) 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  was waived by Assignee or by any other  entity  involved in  originating  or
servicing a Mortgage Loan;

o.      There is no delinquent tax or assessment lien against any Mortgaged Property;

p.      There are no  mechanics'  liens or claims for work,  labor or material  affecting  any
Mortgaged  Property  which  are or may be a lien  prior  to,  or equal  with,  the lien of the
related  Mortgage,  except  such liens  that are  insured  or  indemnified  against by a title
insurance policy;

q.      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; and

r.      Assignor  shall  indemnify  the  Assignee  and  hold it  harmless  against  any  loss,
liability  or expense  incurred in  connection  with any claim,  demand,  defense or assertion
based on or grounded  upon or  resulting  from,  a breach of the  Assignor's  representations,
warranties and covenants set forth in this Assignment and Assumption Agreement

        No representation  and warranty by Assignor  hereunder  constitutes a waiver of any of
the rights of Assignor with respect to the  representations  and  warranties of Assignee under
the Servicing Agreement.

        6.     The Assignee warrants and represents to, and covenants with, the Assignor that:

a.      The  Assignee  agrees  to be  bound,  as  Owner  by all of the  terms,  covenants  and
conditions  of the Mortgage  Loans and the  Custodial  Agreement  with respect to the Mortgage
Loans and from and after the date  hereof,  the  Assignee  assumes  for the benefit of each of
the Assignor  and the Assignee all of the  Assignor's  obligations  as Owner  thereunder  with
respect to the Mortgage Loans;

b.      The  Assignee  is either  (i) not an  employee  benefit  plan that is  subject  to the
Employee  Retirement  Income  Security Act of 1974, as amended  ("ERISA"),  or Section 4975 of
the Internal  Revenue Code of 1986 (the "Code") (a "Plan") and not a Person  acting,  directly
or  indirectly,  on behalf of or  investing  with  "plan  assets"  of any such Plan or (ii) an
employee  benefit plan that is subject to ERISA and the  assignment  contemplated  herein does
not constitute and will not result in a non-exempt  prohibited  transaction  under Section 406
of ERISA or Section 4975 of the Code; and

c.      The Assignee  shall  indemnify  the  Assignor  and hold it harmless  against any loss,
liability  or expense  incurred in  connection  with any claim,  demand,  defense or assertion
based on or grounded  upon or  resulting  from,  a breach of the  Assignee's  representations,
warranties and covenants set forth in this Assignment and Assumption Agreement.
