knowledge,
  
with the exception of one Mortgage Loan
  
representing 0.1% of the Mortgage Loans, if
         
a Mortgage Loan is secured by a Mortgaged
  
Property with a Loan-to-Value
  
Ratio at origination in excess of 80%, such Mortgage
         
Loan is the subject of a Primary
  
Insurance Policy that insures that (a) at least 30% of the Stated
  
Principal
  
Balance of the
         
Mortgage Loan at origination
  
if the
  
Loan-to-Value
  
Ratio is between
  
95.00% and 90.01%,
  
(b) at least 25% of such balance if
         
the
  
Loan-to-Value
  
Ratio is between
  
90.00% and 85.01%,
  
and (c) at least 12% of such balance if the
  
Loan-to-Value
  
Ratio is
         
between 85.00% and 80.01%.
  
To the best of the Company's
  
knowledge,
  
each such Primary
  
Insurance Policy is in full force and
         
effect and the Trustee is entitled to the benefits thereunder;
 
(v)
      
The issuers of the Primary Insurance Policies are insurance
companies whose claims-paying
  
abilities are currently
  
acceptable
         
to each Rating Agency;
 
(vi)
     
No more than 33.8%,
  
43.3%,
  
and 40.8% of the cut-off date
  
principal
  
balance of the Group I Loans,
  
Group II Loans and Group
         
III Loans,
  
respectively,
  
are located in California.
  
No more than 12.6% and 14.4% of the cut-off date
  
principal
  
balance of
         
the Group I Loans and the Group III Loans, respectively, are
located in Virginia;
 
(vii)
    
The improvements
  
upon the Mortgaged
  
Properties are insured against loss by fire and other hazards as
required by the Program
         
Guide,
  
including
  
flood
  
insurance if required
  
under the National
  
Flood
  
Insurance
  
Act of 1968,
  
as amended.
  
The Mortgage
         
requires the Mortgagor to maintain such casualty insurance at the
Mortgagor's
  
expense,
  
and on the Mortgagor's
  
failure to do
         
so,
  
authorizes
  
the holder of the
  
Mortgage to obtain and maintain
  
such
  
insurance
  
at the
  
Mortgagor's
  
expense and to seek
         
reimbursement therefor from the Mortgagor;
 
(viii)
   
Immediately
  
prior to the
  
assignment
  
of the Mortgage
  
Loans to the Trustee,
  
the Company 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 such
  
assignment
  
validly
  
transfers
  
ownership of the Mortgage Loans to the Trustee
         
free and clear of any pledge, lien, encumbrance or security
interest;
 
(ix)
     
No more than 30.8%,
  
47.0%,
  
and 33.7% of the Group I Loans,
  
Group II Loans and Group III Loans,
  
respectively,
  
by aggregate
         
Stated Principal Balance as of the Cut-off Date, were underwritten
under a reduced loan documentation program;
 
(x)
      
Each
  
Mortgagor
  
represented in its loan
  
application
  
with respect to the related
  
Mortgage Loan that the Mortgaged
  
Property
         
would be
  
owner-occupied
  
and
  
therefore
  
would not be an investor
  
property as of the date of
  
origination
  
of such
  
Mortgage
         
Loan.
  
No Mortgagor is a corporation or a partnership;
 
(xi)
     
None of the Group I Loans, Group II Loans or Group III Loans as of
the Cut-off Date are Buydown Mortgage Loans;
 
(xii)
    
Each Mortgage Loan constitutes a qualified mortgage under
  
Section 860G(a)(3)(A)
  
of the Code and Treasury Regulations Section
         
1.860G-2(a)(1);
 
(xiii)
   
A policy of title
  
insurance
  
was
  
effective as of the closing of each
  
Mortgage
  
Loan and is valid and binding and remains in
         
full force and effect,
  
unless the Mortgaged
  
Properties
  
are located in the State of Iowa and an attorney's
  
certificate
  
has
         
been provided as described in the Program Guide;
 
(xiv)
    
No Mortgage Loan is a Cooperative Loan;
 
(xv)
     
With respect to each Mortgage Loan
  
originated
  
under a "streamlined"
  
Mortgage Loan program
  
(through which no new or updated
         
appraisals
  
of
  
Mortgaged
  
Properties
  
are
  
obtained in
  
connection
  
with the
  
refinancing
  
thereof),
  
the related
  
Seller has
         
represented
  
that either (a) the value of the related
  
Mortgaged
  
Property as of the date the Mortgage Loan was originated was
         
not less than the
  
appraised
  
value of such property at the time of
  
origination
  
of the
  
refinanced
  
Mortgage Loan or (b) the
         
Loan-to-Value 
 
Ratio of the Mortgage Loan as of the date of
  
origination
  
of the Mortgage Loan
  
generally
  
meets the Company's
         
underwriting guidelines;
 
(xvi)
    
Interest on each Mortgage Loan is calculated on the basis of a
360-day year consisting of twelve 30-day months;
 
(xvii)
   
None of the Mortgage Loans contains in the related Mortgage File a
Destroyed Mortgage Note; and
 
(xviii)
  
None of the Mortgage Loans are Pledged Asset Loans or Additional
Collateral Loans.
 
It is understood and agreed that the
  
representations
  
and warranties set forth in this
  
Section 2.03(b)
  
shall survive delivery of the
respective Custodial Files to the Trustee or any Custodian.
 
         
Upon
  
discovery
  
by any of the
  
Company,
  
the
  
Master
  
Servicer,
  
the
  
Trustee
  
or any
  
Custodian
  
of a
  
breach
  
of any of the
representations
  
and
  
warranties
  
set forth in this
  
Section 2.03(b)
  
that
  
materially
  
and
  
adversely
  
affects
  
the
  
interests
  
of the
Certificateholders
  
in any Mortgage Loan, the party
  
discovering such breach shall give prompt written notice to the
other parties (any
Custodian being so obligated under a Custodial Agreement);
  
provided,
  
however, that in the event of a breach of the representation and
warranty set forth in Section
  
2.03(b)(xii),
  
the party
  
discovering
  
such breach shall give such notice within five days of discovery.
Within 90 days of its
  
discovery
  
or its receipt of notice of breach,
  
the Company
  
shall
  
either (i) cure such breach in all
  
material
respects or (ii) purchase
  
such
  
Mortgage
  
Loan from the Trust Fund at the Purchase
  
Price and in the manner set forth in Section 2.02;
provided that the Company shall have the option to substitute a
Qualified
  
Substitute
  
Mortgage Loan or Loans for such Mortgage Loan if
such
  
substitution
  
occurs
  
within two years
  
following
  
the Closing
  
Date;
  
provided
  
that if the
  
omission or defect
  
would cause the
Mortgage Loan to be other than a "qualified
  
mortgage" as defined in Section
  
860G(a)(3) of the Code, any such cure or repurchase
  
must
occur within 90 days from the date such breach was discovered.
  
Any such
  
substitution
  
shall be effected by the Company under the same
terms and
  
conditions as provided in Section 2.04 for
  
substitutions
  
by
  
Residential
  
Funding.
  
It is
  
understood
  
and agreed that the
obligation
  
of the
  
Company to cure such breach or to so purchase 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
  
Certificateholders
  
or the Trustee
on behalf of the
  
Certificateholders.
  
Notwithstanding
  
the
  
foregoing,
  
the Company shall not be required to cure breaches or purchase
or
  
substitute
  
for Mortgage
  
Loans as provided in this Section
  
2.03(b) if the substance of the breach of a
  
representation
  
set forth
above also constitutes fraud in the origination of the Mortgage
Loan.
 
Section 2.04
      
Representations and Warranties of Sellers.
 
         
The
  
Company,
  
as assignee of
  
Residential
  
Funding
  
under the
  
Assignment
  
Agreement,
  
hereby
  
assigns to the Trustee for the
benefit of
  
Certificateholders
  
all of its right, title and interest in respect of the Assignment
Agreement and each Seller's Agreement
(to the
  
extent
  
assigned
  
to the
  
Company
  
pursuant
  
to the
  
Assignment
  
Agreement)
  
applicable
  
to a
  
Mortgage
  
Loan.
  
Insofar as the
Assignment
  
Agreement or the Company's
  
rights under such Seller's
  
Agreement
  
relate to the
  
representations
  
and
  
warranties
  
made by
Residential
  
Funding or the related
  
Seller in respect of such Mortgage
  
Loan and any remedies
  
provided
  
thereunder
  
for any breach of
such
  
representations
  
and warranties,
  
such right,
  
title and interest may be enforced by the Master Servicer on behalf
of the Trustee
and the
  
Certificateholders.
  
Upon the discovery by the Company,
  
the Master Servicer,
  
the Trustee or any Custodian of a breach of any
of the
  
representations
  
and warranties
  
made in a Seller's
  
Agreement that have been assigned to the Trustee
  
pursuant to this Section
2.04 or of a breach of any of the
  
representations
  
and warranties made in the Assignment
  
Agreement (which, for purposes hereof,
  
will
be deemed to include
  
any other
  
cause
  
giving
  
rise to a
  
repurchase
  
obligation
  
under the
  
Assignment
  
Agreement)
  
in respect of any
Mortgage
  
Loan which
  
materially
  
and adversely
  
affects the
  
interests of the
  
Certificateholders
  
in such
  
Mortgage
  
Loan,
  
the party
discovering
  
such breach shall give prompt
  
written
  
notice to the other parties (any
  
Custodian
  
being so obligated
  
under a Custodial
Agreement).
  
The Master
  
Servicer shall promptly notify the related Seller or Residential
  
Funding,
  
as the case may be, of such breach
and request that such Seller or Residential
  
Funding,
  
as the case may be, either (i) cure such breach in all material
  
respects within
90 days from the date the Master
  
Servicer was notified of such breach or (ii)
  
purchase
  
such Mortgage Loan from the Trust Fund at the
Purchase
  
Price and in the manner set forth in Section
  
2.02;
  
provided
  
that in the case of a breach
  
under the
  
Assignment
  
Agreement
Residential
  
Funding shall have the option to substitute a Qualified
  
Substitute
  
Mortgage Loan or Loans for such Mortgage Loan if such
substitution
  
occurs
  
within two years
  
following
  
the Closing
  
Date;
  
provided
  
that if the breach would cause the Mortgage Loan to be
other than a "qualified
  
mortgage" as defined in Section
  
860G(a)(3) of the Code, any such cure,
  
repurchase or substitution must occur
within
  
90 days
  
from the date the
  
breach
  
was
  
discovered.
  
If the
  
breach
  
of
  
representation
  
and
  
warranty
  
that
  
gave rise to the
obligation to repurchase or substitute a Mortgage Loan pursuant to
Section 4 of the
  
Assignment
  
Agreement was the
  
representation
  
and
warranty set forth in clause (xii) of Section 4 thereof, 
 
then the Master
  
Servicer shall request that
  
Residential
  
Funding 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.
  
In the event that Residential
  
Funding
elects to
  
substitute
  
a Qualified
  
Substitute
  
Mortgage
  
Loan or Loans for a Deleted
  
Mortgage
  
Loan
  
pursuant to this
  
Section
  
2.04,
Residential Funding shall deliver to the Trustee for the benefit of
the
  
Certificateholders
  
with respect to such Qualified
  
Substitute
Mortgage 
 
Loan or Loans,
  
the original
  
Mortgage
  
Note,
  
the Mortgage,
  
an
  
Assignment
  
of the Mortgage in recordable
  
form if required
pursuant to Section 2.01, and such other documents and agreements
as are required by
  
Section 2.01,
  
with the Mortgage Note endorsed as
required by Section 2.01. No
  
substitution
  
will be made in any calendar
  
month after the
  
Determination
  
Date for such month.
  
Monthly
Payments due with respect to Qualified
  
Substitute
  
Mortgage Loans in the month of substitution shall not be part of
the Trust Fund and
will be
  
retained
  
by the
  
Master
  
Servicer
  
and
  
remitted
  
by the
  
Master
  
Servicer
  
to
  
Residential
  
Funding
  
on the next
  
succeeding
Distribution
  
Date. For the month of substitution,
  
distributions to the
  
Certificateholders
  
will include the Monthly Payment due on a
Deleted
  
Mortgage Loan for such month and thereafter
  
Residential
  
Funding shall be entitled to retain all amounts
  
received in respect
of such Deleted
  
Mortgage Loan. The Master
  
Servicer shall amend or cause to be amended the Mortgage Loan
Schedule,
  
for the benefit of
the
  
Certificateholders
  
to reflect the removal of such Deleted Mortgage Loan and the
substitution of the Qualified Substitute Mortgage
Loan or Loans and the Master Servicer shall deliver the amended
Mortgage Loan Schedule,
  
to the Trustee.
  
Upon such
  
substitution,
  
the
Qualified Substitute Mortgage Loan or Loans shall be subject to the
terms of this Agreement and the related
  
Subservicing
  
Agreement in
all
  
respects,
  
the related
  
Seller shall be deemed to have made the
  
representations
  
and
  
warranties
  
with
  
respect to the
  
Qualified
Substitute Mortgage Loan contained in the related Seller's
Agreement as of the date of substitution,
  
insofar as Residential
  
Funding's
rights in respect of such
  
representations
  
and warranties are assigned to the Company
  
pursuant to the Assignment
  
Agreement,
  
and the
Company and the Master
  
Servicer shall be deemed to have made with respect to any Qualified
  
Substitute
  
Mortgage Loan or Loans,
  
as of
the date of substitution,
  
the covenants,
  
representations and warranties set forth in this Section 2.04, in
Section 2.03 hereof and in
Section 4 of the
  
Assignment
  
Agreement,
  
and the Master
  
Servicer
  
shall be obligated to repurchase
  
or
  
substitute
  
for any Qualified
Substitute
  
Mortgage Loan as to which a Repurchase
  
Event (as defined in the Assignment
  
Agreement) has occurred
  
pursuant to Section 4
of the Assignment Agreement.
 
         
In connection
  
with the
  
substitution
  
of one or more Qualified
  
Substitute
  
Mortgage
  
Loans for one or more Deleted
  
Mortgage
Loans,
  
the Master
  
Servicer
  
will
  
determine
  
the
  
amount
  
(if any) by which the
  
aggregate
  
principal
  
balance of all such
  
Qualified
Substitute
  
Mortgage
  
Loans as of the date of
  
substitution
  
is less than the aggregate
  
Stated
  
Principal
  
Balance of all such Deleted
Mortgage Loans (in each case after
  
application of the principal
  
portion of the Monthly Payments due in the month of substitution
that
are to be distributed to the
  
Certificateholders
  
in the month of substitution).
  
Residential
  
Funding shall deposit the amount of such
shortfall into the Custodial Account on the day of substitution,
  
without any reimbursement
  
therefor.
  
Residential
  
Funding shall give
notice in writing to the Trustee of such event,
  
which notice shall be
  
accompanied by an Officers'
  
Certificate as to the
  
calculation
of such
  
shortfall
  
and
  
(subject to Section
  
10.01(f))
  
by an Opinion of Counsel to the effect that such
  
substitution
  
will not cause
(a) any
  
federal
  
tax to be
  
imposed
  
on the Trust
  
Fund,
  
including
  
without
  
limitation,
  
any
  
federal
  
tax
  
imposed
  
on
  
"prohibited
transactions"
  
under Section
  
860F(a)(1) of the Code or on "contributions
  
after the startup date" under Section 860G(d)(1) of the Code
or (b) any portion of any REMIC to fail to qualify as such at any
time that any Certificate is outstanding.
 
         
It is
  
understood
  
and agreed
  
that the
  
obligation
  
of the Seller or
  
Residential
  
Funding,
  
as the case may be, to cure such
breach or
  
purchase
  
(or in the case of
  
Residential
  
Funding
  
to
  
substitute
  
for) such
  
Mortgage
  
Loan as to which
  
such a breach has
occurred and is continuing and to make any additional
  
payments required under the Assignment
  
Agreement in connection with a breach of
the
  
representation
  
and
  
warranty
  
in clause
  
(xii) of Section 4 thereof
  
shall
  
constitute
  
the sole
  
remedy
  
respecting
  
such breach
available to the
  
Certificateholders
  
or the Trustee on behalf of
  
Certificateholders.
  
If the Master Servicer is Residential 
 
Funding,
then the Trustee
  
shall also have the right to give the
  
notification
  
and require the
  
purchase or
  
substitution
  
provided
  
for in the
second
  
preceding
  
paragraph
  
in the
  
event of such a breach
  
of a
  
representation
  
or
  
warranty
  
made by
  
Residential
  
Funding
  
in the
Assignment
  
Agreement.
  
In connection
  
with the purchase of or
  
substitution
  
for any such Mortgage Loan by
  
Residential
  
Funding,
  
the
Trustee shall assign to Residential
  
Funding all of the Trustee's
  
right,
  
title and interest in respect of the Seller's
  
Agreement and
the Assignment Agreement applicable to such Mortgage Loan.

(a)
      
The Master
  
Servicer
  
may
  
continue
  
in effect
  
Subservicing
  
Agreements
  
entered
  
into by
  
Residential
  
Funding
  
and
Subservicers prior to the execution and delivery of this Agreement,
  
and may enter into new Subservicing
  
Agreements with Subservicers,
for the servicing and
  
administration
  
of all or some of the Mortgage Loans.
  
Each
  
Subservicer
  
shall be either (i) an institution the
accounts of which are insured by the FDIC or (ii)
  
another
  
entity that engages in the business of
  
originating
  
or servicing
  
mortgage
loans,
  
and in either case shall be authorized to transact
  
business in the state or states in which the related
  
Mortgaged
  
Properties
it is to service are situated,
  
if and to the extent
  
required by applicable law to enable the
  
Subservicer to perform its
  
obligations
hereunder
  
and under the
  
Subservicing
  
Agreement,
  
and in either
  
case shall be a Freddie
  
Mac,
  
Fannie Mae or HUD
  
approved
  
mortgage
servicer.
  
In addition,
  
any
  
Subservicer of a Mortgage Loan insured by the FHA must be an
FHA-approved
  
servicer,
  
and any Subservicer
of a Mortgage Loan
  
guaranteed
  
by the VA must be a
  
VA-approved
  
servicer.
  
Each
  
Subservicer
  
of a Mortgage Loan shall be entitled to
receive and retain, as provided in the related
  
Subservicing
  
Agreement and in Section 3.07, the related Subservicing Fee from
payments
of interest
  
received on such Mortgage Loan after payment of all amounts
  
required to be remitted to the Master
  
Servicer in respect of
such Mortgage Loan.
  
For any Mortgage Loan that is a
  
Nonsubserviced
  
Mortgage
  
Loan, the Master
  
Servicer shall be entitled to receive
and retain an amount equal to the
  
Subservicing Fee from payments of interest.
  
Unless the context
  
otherwise
  
requires,
  
references in
this Agreement to actions taken or to be taken by the Master
  
Servicer in servicing the Mortgage
  
Loans include
  
actions taken or to be
taken by a Subservicer
  
on behalf of the Master
  
Servicer.
  
Each
  
Subservicing
  
Agreement will be upon such terms and conditions as are
generally
  
required by,
  
permitted by or consistent
  
with the Program
  
Guide and are not
  
inconsistent
  
with this
  
Agreement and as the
Master
  
Servicer and the
  
Subservicer
  
have agreed;
  
provided that, the
  
Subservicing
  
Agreement
  
between the Master Servicer and Wells
Fargo,
  
if any,
  
will be upon such terms and
  
conditions
  
as are
  
consistent
  
with this
  
Agreement
  
and as the Master
  
Servicer and the
Subservicer have agreed,
  
which may not be consistent with the Program Guide.
  
With the approval of the Master Servicer,
  
a Subservicer
may delegate its
  
servicing
  
obligations
  
to
  
third-party
  
servicers,
  
but such
  
Subservicer
  
will remain
  
obligated
  
under the related
Subservicing
  
Agreement.
  
The Master Servicer and a Subservicer
  
may enter into amendments
  
thereto or a different form of Subservicing
Agreement,
  
and the form referred to or included in the Program
  
Guide is merely
  
provided for
  
information
  
and shall not be deemed to
limit in any
  
respect the
  
discretion
  
of the Master
  
Servicer to modify or enter into
  
different
  
Subservicing
  
Agreements;
  
provided,
however,
  
that any such
  
amendments or different forms shall be consistent with and not
violate the provisions of either this Agreement
or the Program Guide in a manner which would
  
materially
  
and adversely
  
affect the
  
interests of the
  
Certificateholders.
  
The Program
Guide and any other
  
Subservicing
  
Agreement entered into between the Master Servicer and any
Subservicer shall require the Subservicer
to accurately and fully report its borrower credit files to each of
the Credit Repositories in a timely manner.

Certificate
  
Interest on any Class of
  
Certificates
results from an interest rate reduction in connection with a
Servicing
  
Modification,
  
or (2) such unpaid Accrued Certificate
  
Interest
was
  
attributable
  
to
  
interest
  
shortfalls
  
relating

failure of the Master
  
Servicer
  
to make any
  
required
  
Advance,

For any

Amount,
  
in
  
reduction
  
of
  
the
  
Certificate
  
Principal

of
  
such
Undercollateralized

until such Certificate
  
Principal Balance equals the aggregate Stated Principal Balance of
the
Mortgage Loans in the related Loan Group and (ii) an amount equal
to one month's
  
interest at the
  
Pass-Through
  
Rate for such Class or
Classes of the Undercollateralized
  
Certificate Group on the related
  
Undercollateralized
  
Amount will be distributed from that portion
of the Available
  
Distribution
  
Amount for any
  
non-related
  
Loan Groups that would be otherwise
  
allocable to the Class M Certificates
and Class B Certificates,
  
in the following priority:
  
first to pay any unpaid interest on such
  
Undercollateralized
  
Certificate Group
and then to pay principal
  
thereon in the priorities set forth in Section
  
4.02(b).
  
If there exists more than one
  
Undercollateralized
Certificate
  
Group on a Distribution
  
Date,
  
amounts
  
distributable
  
to such
  
Undercollateralized
  
Certificate
  
Groups
  
pursuant to the
preceding
  
sentence will be allocated
  
between such
  
Undercollateralized
  
Certificate
  
Groups,
  
pro rata,
  
based upon their
  
respective
Undercollateralized Amounts.
 
(e)
      
After reduction of the Certificate
  
Principal Balances of the Senior
  
Certificates in a Certificate Group to zero but prior to
the Credit
  
Support
  
Depletion
  
Date,
  
such Class or Classes of Senior
  
Certificates
  
will be entitled to no further
  
distributions
  
of
principal thereon and the related Available
  
Distribution
  
Amount will be paid (subject to Section 4.02(c) above) solely to
the holders
of the Subordinate Certificates, in each case as described herein.
 
(f)
      
On or after the occurrence of the Credit Support
  
Depletion
  
Date, all priorities
  
relating to
  
distributions
  
as described in
clause (b) above in respect of principal among the various classes
of Senior
  
Certificates will be disregarded,
  
and (i) the applicable
Senior
  
Principal
  
Distribution
  
Amount
  
will be
  
distributed
  
to the
  
remaining
  
Classes of related
  
Senior
  
Certificates
  
pro rata in
accordance with their respective
  
outstanding
  
Certificate
  
Principal
  
Balances,
  
and (ii) the amounts set forth in Section

will be distributed as set forth therein.
 
(g)
      
In addition to the foregoing

Subsequent
  
Recoveries,
  
the Master
  
Servicer shall deposit
such funds into the Custodial
  
Account
  
pursuant to Section
  
3.07(b)(iii).
  
If, after taking into account such
  
Subsequent
  
Recoveries,
the amount of a Realized
  
Loss is
  
reduced,
  
the amount of such
  
Subsequent
  
Recoveries
  
will be applied to
  
increase
  
the
  
Certificate
Principal
  
Balance of the Class of Subordinate
  
Certificates
  
with the Highest Priority to which Realized Losses,
  
have been allocated,
but not by more than the amount of Realized Losses
  
previously
  
allocated to that Class of
  
Certificates
  
pursuant to Section 4.05. The
amount of any
  
remaining
  
Subsequent
  
Recoveries
  
will be
  
applied
  
to
  
increase
  
the
  
Certificate
  
Principal
  
Balance
  
of the Class of
Certificates
  
with
  
the
  
next
  
Lower
  
Priority,
  
up to the
  
amount
  
of such
  
Realized
  
Losses
  
previously
  
allocated
  
to that
  
Class of
Certificates
  
pursuant to Section
  
4.05.
  
Any
  
remaining 
 
Subsequent
  
Recoveries
  
will in turn be applied to increase
  
the
  
Certificate
Principal
  
Balance of the Class of
  
Certificates
  
with the next Lower
  
Priority
  
up to the amount of such
  
Realized
  
Losses
  
previously
allocated to that Class of
  
Certificates 
 
pursuant to Section 4.05,
  
and so on.
  
Holders of such
  
Certificates
  
will not be entitled to
any payment in respect of Accrued
  
Certificate
  
Interest on the amount of such increases for any Interest
  
Accrual Period preceding the
Distribution
  
Date on which such increase
  
occurs.
  
Any such increases
  
shall be applied to the Certificate
  
Principal
  
Balance of each
Certificate of such Class in accordance with its respective
Percentage Interest.
 
(h)
      
Each
  
distribution
  
with respect to a Book-Entry
  
Certificate
  
shall be paid to the
  
Depository,
  
as Holder
  
thereof,
  
and the
Depository
  
shall be solely
  
responsible for crediting the amount of such
  
distribution to the accounts of its Depository
  
Participants
in accordance with its normal
  
procedures.
  
Each Depository
  
Participant
  
shall be responsible for disbursing such
  
distribution to the
Certificate
  
Owners that it represents
  
and to each indirect
  
participating
  
brokerage
  
firm (a "brokerage
  
firm") for which it acts as
agent.
  
Each
  
brokerage
  
firm shall be
  
responsible
  
for disbursing
  
funds to the
  
Certificate
  
Owners that it represents.
  
None of the
Trustee, the Certificate Registrar, the Company or the Master
Servicer shall have any responsibility therefor.
 
(i)
      
Except as otherwise
  
provided in Section 9.01, if the Master Servicer
  
anticipates that a final
  
distribution
  
with respect to
any Class of Certificates
  
will be made on a future
  
Distribution
  
Date, the Master Servicer shall, no later than 40 days prior to
such
final
  
distribution,
  
notify the Trustee and the Trustee
  
shall,
  
not earlier
  
than the 15th day and not later than the 25th day of the
month next
  
preceding
  
the month of such final
  
distribution,
  
distribute
  
or cause to be
  
distributed
  
to each Holder of such Class of
Certificates
  
a notice to the effect
  
that:
  
(i) the Trustee
  
anticipates
  
that the final
  
distribution
  
with
  
respect to such Class of
Certificates
  
will be made on such
  
Distribution
  
Date but only upon
  
presentation and surrender of such
  
Certificates at the office of
the Trustee or as otherwise
  
specified
  
therein,
  
and (ii) no interest shall accrue on such
  
Certificates from and after the end of the
prior calendar month. In the event that
  
Certificateholders
  
required to surrender
  
their
  
Certificates
  
pursuant to Section 9.01(c) do
not
  
surrender
  
their
  
Certificates
  
for final
  
cancellation,
  
the
  
Trustee
  
shall
  
cause
  
funds
  
distributable
  
with
  
respect
  
to such
Certificates
  
to be
  
withdrawn
  
from the
  
Certificate
  
Account
  
and
  
credited
  
to a separate
  
escrow
  
account
  
for the
  
benefit of such
Certificateholders as provided in Section 9.01(d).

Modification,
  
Debt Service
  
Reduction,

that
occurred

Period or, in the case of a
  
Servicing
  
Modification
  
that

Losses will be allocated as set forth
  
herein after
  
distributions

As used herein,
  
an allocation of a Realized Loss on a "pro rata basis" among two or
more 
 
specified
  
Classes of
  
Certificates
means an allocation on a pro rata basis,
  
among the various
  
Classes so specified,
  
to each such Class of
  
Certificates on the basis of
their then outstanding
  
Certificate
  
Principal Balances prior to giving effect to distributions to be
made on such Distribution Date in
the
  
case of the
  
principal
  
portion
  
of a
  
Realized
  
Loss or
  
based
  
on the
  
Accrued
  
Certificate
  
Interest
  
thereon
  
payable
  
on such
Distribution
  
Date (without regard to any
  
Compensating
  
Interest for such
  
Distribution
  
Date) in the case of an interest portion of a
Realized Loss.
  
Except as provided in the following
  
sentence,
  
any allocation of the principal
  
portion of Realized
  
Losses to a Class
of
  
Certificates
  
shall be made by reducing the Certificate
  
Principal
  
Balance
  
thereof by the amount so allocated,
  
which
  
allocation
shall be deemed to have occurred on such
  
Distribution
  
Date;
  
provided that no such reduction
  
shall reduce the aggregate
  
Certificate
Principal
  
Balance of the
  
Certificates
  
below the aggregate
  
Stated
  
Principal
  
Balance of the Mortgage
  
Loans.
  
Any allocation of the
principal
  
portion of Realized
  
Losses to the
  
Subordinate
  
Certificates
  
then
  
outstanding
  
with the Lowest
  
Priority shall be made by
operation of the definition of "Certificate
  
Principal
  
Balance" and by operation of the provisions of Section 4.02(a).
  
Allocations of
the interest
  
portions of Realized
  
Losses (other than any interest rate reduction
  
resulting from a Servicing
  
Modification)
  
shall be
made in proportion to the amount of Accrued Certificate Interest
and by operation of the definition of "Accrued
  
Certificate
  
Interest"
and by operation of the
  
provisions
  
of Section
  
4.02(a).
  
Allocations
  
of the interest
  
portion of a Realized Loss
  
resulting
  
from an
interest rate reduction in connection with a Servicing
  
Modification
  
shall be made by operation of the provisions of Section
  
4.02(a).
All Realized
  
Losses and all other losses
  
allocated to a Class of Certificates
  
hereunder will be allocated among the
  
Certificates of
such Class in proportion to the Percentage Interests evidenced
thereby.

shall
  
then be deemed to be made to the

Date,
  
the least amount of Realized

shall be deemed
  
made by the
  
Trustee to itself,
  
as the holder of the
Uncertificated REMIC II Regular Interests, in accordance with the
priority set forth in subsection (f) below.
(f)
      
The amount
  
described in subsection

distributed
  
with respect to
  
Uncertificated

R-II
  
Certificates
  
in accordance with the
priority assigned to such Certificates under Section 4.02.

Uncertificated
  
REMIC I Regular
  
Interests in accordance
with the priority
  
assigned to each related Class of Certificates
  
(other than the Class R Certificates),
  
respectively,
  
under Section

(h)
      
Notwithstanding
  
the deemed
  
distributions on the
  
Uncertificated
  
REMIC I Regular Interests and the
  
Uncertificated
  
REMIC II
Regular Interests,
  
as the case may be, described in this Section 10.04,
  
distributions of funds from the Certificate
  
Account shall be
made only in accordance with Section 4.02.
 
Section 10.05

Notwithstanding any other provision of this Agreement,
  
the Trustee or any Paying Agent, as applicable,
  
shall comply with all
federal withholding
  
requirements respecting payments to Certificateholders,
  
including interest or original issue discount payments or
advances
  
thereof that the Trustee or any Paying Agent, as applicable,
  
reasonably
  
believes are applicable under the Code. The consent
of
  
Certificateholders
  
shall not be required for such withholding.
  
In the event the Trustee or any Paying Agent, as applicable,
  
does
withhold
  
any amount from

issue
  
discount
  
payments
  
or advances
  
thereof to any
  
Certificateholder
  
pursuant to
federal
  
withholding
  
requirements,
  
the
  
Trustee or any Paying
  
Agent,
  
as
  
applicable,
  
shall
  
indicate
  
the amount
  
withheld to such
Certificateholder pursuant to the terms of such requirements.
