Delinquency
  
Test Violation:
  
If on any
  
Distribution
  
Date, the percentage
  
obtained by dividing
(x) the aggregate
  
outstanding principal balance of the mortgage loans that are 60
days or more Delinquent
or are in bankruptcy or
  
foreclosure
  
or are REO
  
Properties
  
by (y) the aggregate
  
Outstanding
  
Principal
Balance of the Mortgage
  
Loans, in each case, as of the last day of the previous
  
calendar month,
  
exceeds
(i) prior to the
  
Distribution
  
Date in November

27.72% of the Credit
  
Enhancement
  
Percentage and
(ii) on or after the Distribution Date in November 2012, 34.65%.
 
         
Delinquent:

"Delinquent"
  
if any payment due thereon is not made pursuant to
the terms of such
  
Mortgage
  
Loan by the close of business on the day such payment is scheduled
to be due.
A Mortgage
  
Loan is "30 days
  
delinquent"
  
if such payment has not been
  
received by the close of business
on the last
  
day of the
  
month
  
immediately
  
succeeding
  
the
  
month in which
  
such
  
payment
  
was due.
  
For
example,
  
a
  
Mortgage
  
Loan with a
  
payment
  
due on
  
December
  
1 that
  
remained
  
unpaid as of the close of
business on January 31 would then be
  
considered
  
to be 30 to 59 days
  
delinquent.
  
Similarly for "60 days
delinquent," "90 days delinquent" and so on.

described
  
above, at no expense to the Trust or the Trustee or the

Section 2.02.
     
Acceptance
  
of
  
Mortgage
  
Loans by
  
Trustee.
  
(a) The Trustee (on behalf of the
Trust)
  
acknowledges
  
the sale,
  
transfer
  
and
  
assignment
  
of the Trust Fund to it by the
  
Depositor
  
and
receipt of,
  
subject to further
  
review and the
  
exceptions
  
which may be noted pursuant to the procedures
described below,
  
and declares that it holds, the documents (or certified copies
thereof)
  
delivered to it
or the
  
Custodian,
  
as its agent,
  
pursuant to
  
Section 2.01,
  
and declares
  
that it will continue to hold
those
  
documents
  
and any
  
amendments,
  
replacements
  
or
  
supplements
  
thereto and all other assets of the
Trust Fund
  
delivered to it as Trustee in trust for the use and benefit of all
present and future
  
Holders
of the
  
Certificates.
  
On the Closing
  
Date,
  
with
  
respect to the Mortgage
  
Loans,
  
the
  
Custodian
  
shall
acknowledge
  
with
  
respect to each
  
Mortgage
  
Loan by
  
delivery
  
to the
  
Depositor
  
and the
  
Trustee of an
Initial
  
Certification
  
receipt of the Mortgage File, but without review of such Mortgage
File,
  
except to
the extent
  
necessary to confirm that such Mortgage
  
File contains the related
  
Mortgage Note or lost note
affidavit.
  
No later than 90 days after the
  
Closing
  
Date (or with
  
respect
  
to any
  
Substitute
  
Mortgage
Loan,
  
within five (5) Business Days after the receipt by the Trustee or
Custodian
  
thereof),
  
the Trustee
agrees, for the benefit of the
  
Certificateholders
  
and the Certificate
  
Insurer, to review or cause to be
reviewed by the Custodian on its behalf (under the Custodial
  
Agreement),
  
each Mortgage File delivered to
it and to execute and deliver,
  
or cause to be executed and
  
delivered,
  
to the
  
Depositor and the Trustee
an Interim
  
Certification.
  
In conducting
  
such review,
  
the Trustee or Custodian will
  
ascertain
  
whether
all required documents have been executed and received,
  
and based on the Mortgage Loan Schedule,
  
whether
those documents
  
relate,
  
determined on the basis of the Mortgagor name,
  
original
  
principal
  
balance and
loan number,
  
to the Mortgage
  
Loans it has received,
  
as identified
  
in the Mortgage
  
Loan
  
Schedule.
  
In
performing
  
any such review,
  
the Trustee or the Custodian,
  
as its agent,
  
may
  
conclusively
  
rely on the
purported due
  
execution and
  
genuineness
  
of any such
  
document and on the purported
  
genuineness
  
of any
signature thereon.
  
If the Trustee or the Custodian,
  
as its agent,
  
finds any document
  
constituting part
of the Mortgage
  
File has not been executed or received,
  
or to be
  
unrelated,
  
determined on the basis of
the Mortgagor
  
name,
  
original
  
principal 
 
balance and loan number,
  
to the Mortgage
  
Loans
  
identified in
Exhibit B,
  
or to appear
  
defective on its face (a "Material
  
Defect"),
  
the Trustee or the Custodian,
  
as
its agent,
  
shall promptly
  
notify the Sponsor.
  
In accordance
  
with the Mortgage Loan Purchase
  
Agreement
the Sponsor
  
shall
  
correct or cure any such defect
  
within
  
ninety (90) days from the date of notice from
the Trustee or the
  
Custodian,
  
as its agent,
  
of the defect and if the
  
Sponsor
  
fails to correct or cure
the defect
  
within such period,
  
and such defect
  
materially
  
and
  
adversely
  
affects the interests of the
Certificateholders
  
in the related
  
Mortgage
  
Loan,
  
the
  
Trustee or the
  
Custodian,
  
as its agent,
  
shall
enforce the Sponsor's
  
obligation
  
pursuant to the Mortgage Loan
  
Purchase
  
Agreement
  
within 90 days from
the Trustee's or the
  
Custodian's
  
notification,
  
to purchase such Mortgage Loan at the Repurchase
  
Price;
provided
  
that,
  
if such defect would cause the Mortgage
  
Loan to be other than a "qualified
  
mortgage" as
defined in
  
Section 860G(a)(3)(A)
  
of the Code and Treasury Regulation Section
  
1.860G-2(a)(1),
  
(2), (4),
(5), (6), (7) and (9), without reliance on the provisions of
Treasury
  
Regulation
  
Section
  
1.860G-2(a)(3)
or Treasury
  
Regulation Section
  
1.860G-2(f)(2) or any other provision that would allow a Mortgage
Loan to
be treated as a
  
"qualified
  
mortgage"
  
notwithstanding
  
its failure to meet the
  
requirements
  
of Section
860G(a)(3)(A)
  
of the Code and Treasury
  
Regulation
  
Section
  
1.860G-2(a)(1),
  
(2), (4), (5), (6), (7) and
(9),
  
any such cure or
  
repurchase
  
must occur
  
within 90 days from the date such
  
breach was
  
discovered;
provided,
  
however,
  
that if such defect
  
relates
  
solely to the
  
inability
  
of the Sponsor to deliver the
original
  
Security
  
Instrument
  
or
  
intervening
  
assignments
  
thereof,
  
or a
  
certified
  
copy
  
because the
originals of such
  
documents,
  
or a certified copy have not been returned by the applicable
  
jurisdiction,
the Sponsor shall not be required to purchase
  
such
  
Mortgage
  
Loan if the Sponsor
  
delivers such original
documents or certified
  
copy promptly upon receipt,
  
but in no event later than 360 days after the Closing
Date.
  
The foregoing
  
repurchase
  
obligation
  
shall not apply in the event that the Sponsor cannot deliver
such original or copy of any document
  
submitted for recording to the appropriate
  
recording office in the
applicable
  
jurisdiction
  
because such
  
document has not been
  
returned by such office;
  
provided that the
Sponsor
  
shall instead
  
deliver a recording
  
receipt of such
  
recording
  
office or, if such receipt is not
available,
  
a certificate
  
confirming
  
that such documents have been accepted for recording,
  
and delivery
to the Trustee or the
  
Custodian,
  
as its agent,
  
shall be effected by the Sponsor
  
within
  
thirty days of
its receipt of the original recorded document.
 
         
(b)
      
No later
  
than 180 days
  
after
  
the
  
Closing
  
Date (or with
  
respect
  
to any
  
Substitute
Mortgage Loan,
  
within five (5) Business Days after the receipt by the Trustee or
the Custodian
  
thereof),
the Trustee or the Custodian,
  
as its agent, will review,
  
for the benefit of the
  
Certificateholders
  
and
the
  
Certificate
  
Insurer,
  
the Mortgage Files delivered to it and will execute and deliver or
cause to be
executed
  
and
  
delivered
  
to the
  
Depositor
  
and the Trustee a Final
  
Certification.
  
In
  
conducting
  
such
review,
  
the Trustee or the Custodian,
  
as its agent,
  
will ascertain whether an original of each document
required to be recorded has been
  
returned from the
  
recording
  
office with evidence of recording
  
thereon
or a certified
  
copy has been obtained
  
from the recording
  
office.
  
If the Trustee or the
  
Custodian,
  
as
its agent,
  
finds a Material
  
Defect,
  
the Trustee or the Custodian,
  
as its agent,
  
shall promptly notify
the Sponsor (provided,
  
however,
  
that with respect to those documents described in Sections
  
2.01(b)(iv),
(v) and (vii),
  
the
  
Trustee's and
  
Custodian's
  
obligations
  
shall extend only to the documents
  
actually
delivered to the Trustee or the Custodian
  
pursuant to such
  
Sections).
  
In
  
accordance
  
with the Mortgage
Loan
  
Purchase
  
Agreement,
  
the Sponsor shall correct or cure any such defect within 90 days
from the date
of notice from the Trustee or the Custodian,
  
as its agent,
  
of the Material
  
Defect and if the Sponsor is
unable to cure such defect within such period,
  
and if such defect
  
materially
  
and adversely
  
affects the
interests
  
of the
  
Certificateholders
  
in the
  
related
  
Mortgage
  
Loan,
  
the
  
Trustee
  
shall
  
enforce
  
the
Sponsor's
  
obligation under the Mortgage Loan Purchase Agreement to provide a
Substitute Mortgage Loan (if
within two years of the Closing Date) or purchase such Mortgage
Loan at the
  
Repurchase
  
Price;
