PRELIMINARY STATEMENT:
 
         
The Company intends to sell mortgage asset-backed pass-through
certificates (collectively,
  
the "Certificates"),
  
to be issued
hereunder in multiple classes, which in the aggregate will evidence
the entire beneficial ownership interest in the Mortgage Loans.
 
         
The terms and

Terms are hereby
  
incorporated
  
by
  
reference
  
herein as though set forth in full
herein.
  
If any term or

herein
  
shall
  
conflict
  
with or be
  
inconsistent
  
with any
  
provision
  
contained in the
Standard Terms, the terms and provisions of this Series
  
Supplement shall govern.
  
All capitalized

defined herein
shall have the meanings set forth in the Standard
  
Terms.
  
The Pooling and

REMIC I
 
         
As provided herein,
  
the REMIC
  
Administrator
  
will make an election to treat the segregated pool of assets
  
consisting of the
Mortgage Loans and certain other related

conduit (a "REMIC") for federal
  
income tax
  
purposes,
  
and such
  
segregated
  
pool of assets will be
designated as "REMIC I." The Class R-I
  
Certificates
  
will represent the sole Class of "residual
  
interests" in REMIC I for purposes of
the REMIC

for each REMIC I Regular
  
Interest
  
shall be the Maturity
  
Date.
  
None of the REMIC I Regular
  
Interests
  
will be
certificated.
 
                                           
Uncertificated

Amounts:
  
For any

amounts by which the
  
Uncertificated
  
Principal
Balances of REMIC II-A
  
Regular
  
Interests Y-1 and Y-2,
  
respectively,
  
will be reduced on such
  
distribution date by the allocation of
Realized Losses and the distribution of principal, determined as
follows:
 
         
First for each of Loan Group I and Loan Group II
  
determine the Group I Net WAC Rate and Group II Net WAC Rate,
  
respectively,
for distributions of interest that will be made on the next
succeeding
  
Distribution
  
Date (the "Group Interest Rate").
  
The REMIC II-A
Principal
  
Reduction
  
Amount for each of the REMIC II-A Y Regular
  
Interests will be determined
  
pursuant to the "Generic
  
solution for
the REMIC II-A Y Regular
  
Interests" set forth below (the "Generic
  
Solution") by making the following
  
identifications
  
among the Loan
Groups and their related REMIC II-A Y Regular Interests and REMIC
II-A Z Regular Interests:
 
                  
A.
       
Determine
  
which
  
Loan
  
Group has the lower Net WAC Rate.
  
That
  
Loan
  
Group
  
will be
  
identified
  
with Loan
Group AA and the REMIC II-A Y Regular
  
Interests and
  
REMIC II-A Z Regular
  
Interests
  
related to that Loan Group will be
  
respectively
identified
  
with the
  
REMIC II-A
  
YAA and
  
REMIC II-A
  
ZAA
  
Regular
  
Interests.
  
The Group
  
Interest
  
Rate for that Loan
  
Group will be
identified
  
with J%. If the two Loan Groups have the same Group
  
Interest
  
Rate pick one for this purpose,
  
subject to the
  
restriction
that each Loan Group may be picked only once in the course of any
such selections pursuant to paragraphs A and B of this definition.
 
                  
B.
       
Determine
  
which
  
Loan Group has the higher
  
Net WAC Rate.
  
That Loan
  
Group
  
will be
  
identified
  
with Loan
Group BB
  
and the 
 
REMIC II-A
  
Y Regular
  
Interests
  
and
  
REMIC II-A
  
Z Regular
  
Interests
  
related to that Group will be
  
respectively
identified
  
with the
  
REMIC II-A
  
YBB and
  
REMIC II-A
  
ZBB
  
Regular
  
Interests.
  
The Group
  
Interest
  
Rate for that Loan
  
Group will be
identified
  
with K%. If the two Loan Groups have the same Group
  
Interest
  
Rate the Loan Group not
  
selected
  
pursuant to
  
paragraph A,
above, will be selected for purposes of this paragraph B.
 
         
Second,
  
apply the Generic
  
Solution
  
set forth below to
  
determine
  
the
  
REMIC II-A
  
Y
  
Principal
  
Reduction
  
Amounts for the
Distribution Date using the identifications made above.
 
         
Generic
  
Solution for the
  
REMIC II-A Y Principal
  
Reduction
  
Amounts:
  
For any
  
Distribution
  
Date,
  
the amounts by which the
Uncertificated
  
Principal
  
Balances of
  
REMIC II-A
  
YAA and
  
REMIC II-A
  
ZAA
  
Regular
  
Interests
  
respectively
  
will be reduced on such
Distribution Date by the allocation of Realized Losses and the
distribution of principal, determined as follows:
 
                  
J% and K% represent the interest rates on Loan Group AA and Loan
Group BB respectively.
  
J% <K%.

The purpose of the foregoing
  
definitional
  
provisions
  
together with the related
  
provisions
  
allocating
  
Realized Losses and
defining the REMIC II-A Y and REMIC II-A Z Principal
  
Distribution
  
Amounts is to accomplish the following goals in the following order
of priority:
 
1.
       
Making the ratio of Yk to Yj equal to (gamma) after taking account
of the
  
allocation
  
Realized
  
Losses and the
  
distributions
     
that will be made through end of the Distribution Date to which
such provisions
  
relate and assuring that the Principal
  
Reduction
     
Amount for each of the REMIC II-A
  
YAA,
  
REMIC II-A
  
YBB,
  
REMIC II-A ZAA and REMIC II-A ZBB Regular
  
Interests is greater than or
     
equal to zero for such Distribution Date;
 
2.
       
Making (i) the REMIC II-A
  
YAA Principal
  
Balance less than or equal to 0.0005 of the sum of the REMIC II-A
YAA and REMIC II-A
     
ZAA principal
  
balances and (ii) the REMIC II-A
  
YBB principal
  
balances less than or equal to 0.0005 of the sum of the REMIC II-A
     
YBB and REMIC II-A ZBB Principal
  
Balances in each case after giving effect to allocations of
Realized Losses and distributions to
     
be made through the end of the Distribution Date to which such
provisions relate; and
 
3.
       
Making
  
the
  
larger
  
of (a) the
  
fraction
  
whose
  
numerator
  
is Yk and whose
  
denominator
  
is the sum of Yk and Zk and (b) the
 
    
fraction whose
  
numerator is Yj and whose
  
denominator is the sum of Yj, and Zj as large as possible while
  
remaining less than or
     
equal to 0.0005.
 
                  
In the event of a failure of the foregoing
  
portion of the definition of REMIC II-A Y Principal
  
Reduction
  
Amount to
accomplish
  
both of goals 1 and 2 above,
  
the
  
amounts
  
thereof
  
should be
  
adjusted
  
to so as to
  
accomplish
  
such
  
goals
  
within
  
the
requirement
  
that each
  
REMIC II-A Y Principal
  
Reduction
  
Amount must be less than or equal to the sum of (a) the
  
principal
  
Realized
Losses to be
  
allocated on the related
  
Distribution
  
Date for the related Pool and (b) the
  
remainder
  
of the
  
Available
  
Distribution
Amount for the related Pool or after reduction
  
thereof by the
  
distributions to be made on such Distribution in respect of
interest on
the
  
related
  
REMIC II-A
  
Y and
  
REMIC II-A
  
Z
  
Regular
  
Interests,
  
or,
  
if both of such
  
goals
  
cannot be
  
accomplished
  
within
  
such
requirement,
  
such
  
adjustment
  
as is
  
necessary
  
shall be made to
  
accomplish
  
goal 1 within
  
such
  
requirement.
  
In the
  
event of any
conflict among the provisions of the definition of the
  
REMIC II-A Y Principal
  
Reduction
  
Amounts,
  
such conflict shall be resolved on
the basis of the goals and their priorities set forth above within
the requirement set forth in the preceding sentence.
