This Pooling and Servicing Agreement (this "Agreement") is dated
and
effective as of January 11, 2006, among STRUCTURED ASSET SECURITIES
CORPORATION
II, as Depositor, WACHOVIA BANK, NATIONAL ASSOCIATION, as Master
Servicer, LNR
PARTNERS, INC., as Special Servicer, and LASALLE BANK NATIONAL
ASSOCIATION, as
Trustee.
 
                             
PRELIMINARY STATEMENT:
 
            
The Depositor intends to sell the Certificates, which are to be
issued hereunder in multiple Classes and which in the aggregate
will evidence
the entire beneficial ownership interest in the Trust Fund.
 
            
As provided herein, the Trustee will elect to treat each Early
Defeasance Trust Mortgage Loan, if any, as the primary asset of a
separate REMIC
for federal income tax purposes, and each such REMIC will be
designated as a
"Loan REMIC". The Class R-LR Certificates (if issued in accordance
with Section
2.06) will represent the sole class of "residual interests" in each
and every
Loan REMIC, if any, for purposes of the REMIC Provisions under
federal income
tax law. A separate Loan REMIC Regular Interest will, on the
Closing Date, be
issued with respect to, and will thereafter relate to, each Early
Defeasance
Trust Mortgage Loan, if any, included in a Loan REMIC. Each Loan
REMIC Regular
Interest, if any, issued with respect to, and relating to, an Early
Defeasance
Trust Mortgage Loan in a Loan REMIC, shall also relate to any
successor REO
Trust Mortgage Loan with respect to such Early Defeasance Trust
Mortgage Loan.
Each Loan REMIC Regular Interest, if any, shall: (i) bear a numeric
designation
that is the same as the loan number for the related Early
Defeasance Trust
Mortgage Loan set forth on the Trust Mortgage Loan Schedule; (ii)
accrue
interest at the related per annum rate described in the definition
of "Loan
REMIC Remittance Rate"; and (iii) have an initial Uncertificated
Principal
Balance equal to the Cut-off Date Balance of the related Early
Defeasance Trust
Mortgage Loan. The Legal Final Distribution Date of each Loan REMIC
Regular
Interest, if any, is the Distribution Date immediately following
the third
anniversary of the end of the remaining amortization term (as
determined as of
the Closing Date) of the related Early Defeasance Trust Mortgage
Loan. None of
the Loan REMIC Regular Interests (if issued in accordance with
Section 2.06)
will be certificated. Notwithstanding the foregoing, however, if
the Trust Fund
does not include Early Defeasance Trust Mortgage Loans, then (i)
there will be
no Loan REMICs, (ii) neither the Class R-LR Certificates nor any
Loan REMIC
Regular Interests will be issued and (iii) the provisions of
Section 2.06(b)
will apply.
 
  
          
As provided herein, the Trustee will elect to treat the segregated
pool of assets consisting of the Trust Mortgage Loans (exclusive of
the Early
Defeasance Trust Mortgage Loans, if any, and exclusive of any
collections of
Additional Interest on the ARD Trust Mortgage Loans, if any, after
their
respective Anticipated Repayment Dates), any Loan REMIC Regular
Interests and
certain other related assets subject to this Agreement as 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 Provisions under
federal income
tax law. Two separate REMIC I Regular Interests will, on the
Closing Date, be
issued with respect to, and will thereafter relate to, each Split
Trust Mortgage
Loan, and such REMIC I Regular Interests will bear the following
alphabetic or
alphanumeric designations: (i) "ICB-A" and "ICB-B", respectively,
in the case of
the Intel Corporate Building Trust Mortgage Loan; (ii) "UH-26-A"
and "UH-26-B",
respectively, in the case of the U-Haul-26 Facilities Portfolio
Trust Mortgage
Loan; and (iii) "UH-SAC-A" and "UH-SAC-B", respectively, in the
case of the
U-Haul-SAC Portfolio Trust Mortgage Loan. In addition, a separate
REMIC I
Regular Interest will, on the Closing Date, be issued with respect
to, and will
thereafter relate to, each other Trust Mortgage Loan included in
REMIC I and
each Loan REMIC
 
 
 
 
Regular Interest, if any, included in REMIC I. Each REMIC I Regular
Interest
issued with respect to, and relating to, a Trust Mortgage Loan in
REMIC I, shall
also relate to any successor REO Trust Mortgage Loan with respect
to such Trust
Mortgage Loan. Each REMIC I Regular Interest issued with respect
to, and
relating to, any Loan REMIC Regular Interest, shall also relate to
the Early
Defeasance Trust Mortgage Loan and any successor REO Trust Mortgage
Loan
corresponding to such Loan REMIC Regular Interest. Each REMIC I
Regular Interest
shall: (i) except as otherwise described above with respect to each
of the
respective REMIC I Regular Interests that correspond to a Split
Trust Mortgage
Loan, bear a numeric designation that is the same as the loan
number for the
related Trust Mortgage Loan set forth on the Trust Mortgage Loan
Schedule; (ii)
accrue interest at a per annum rate described in the definition of
"REMIC I
Remittance Rate"; and (iii) have an initial Uncertificated
Principal Balance
equal to (A) $23,960,022 in the case of REMIC I Regular Interest
ICB-A, (B)
$20,039,978 in the case of REMIC I Regular Interest ICB-B, (C)
$18,131,353 in
the case of REMIC I Regular Interest UH-26-A, (D) $5,457,642 in the
case of
REMIC I Regular Interest UH-26-B, (E) $12,454,665 in the case of
REMIC I Regular
Interest UH-SAC-A, (F) $1,795,920 in the case of REMIC I Regular
Interest
UH-SAC-B, and (G) the Cut-off Date Balance of the related Trust
Mortgage Loan in
the case of each other REMIC I Regular Interest. The Legal Final
Distribution
Date of each of the REMIC I Regular Interests is the Distribution
Date
immediately following the third anniversary of the end of the
remaining
amortization term (as determined as of the Closing Date) of the
related Trust
Mortgage Loan. None of the REMIC I Regular Interests will be
certificated.
 
            
As provided herein, the Trustee will elect to treat the segregated
pool of assets consisting of the REMIC I Regular Interests as a
REMIC for
federal income tax purposes, and such segregated pool of assets
will be
designated as "REMIC II". The Class R-II Certificates will
represent the sole
class of "residual interests" in REMIC II for purposes of the REMIC
Provisions
under federal income tax law. The Legal Final Distribution Date for
each REMIC
II Regular Interest is the latest Rated Final Distribution Date.
None of the
REMIC II Regular Interests will be certificated. Each REMIC II
Regular Interest
shall accrue interest at a per annum rate described in the
definition of "REMIC
II Remittance Rate". The following table sets forth the designation
and the
initial Uncertificated Principal Balance for each of the REMIC II
Regular
Interests.

As provided herein, the Trustee will elect to treat the segregated
pool of assets consisting of the REMIC II Regular Interests as a
REMIC for
federal income tax purposes, and such segregated pool of assets
will be
designated as "REMIC III". The Class R-III Certificates will
evidence the sole
class of "residual interests" in REMIC III for purposes of the
REMIC Provisions
under federal income tax law. For federal income tax purposes, each
Class of the
Regular Interest Certificates (exclusive of the Class X-CL and
Class X-CP
Certificates), each REMIC III Component of the Class X-CL
Certificates and each
REMIC III Component of the Class X-CP Certificates will be
designated as a
separate "regular interest" in REMIC III. The Legal Final
Distribution Date for
each Class of Regular Interest Certificates (exclusive of the Class
X-CL and
Class X-CP Certificates), for each REMIC III Component of the Class
X-CL
Certificates and for each REMIC III Component of the Class X-CP
Certificates is
the latest Rated Final Distribution Date. Each Class of Regular
Interest
Certificates, each REMIC III Component of the Class X-CL
Certificates and each
REMIC III Component of the Class X-CP Certificates will accrue
interest at the
per annum rate described in the definition of "Pass-Through Rate."
The following
table sets forth the Class designation and original Class Principal
Balance for
each Class of the Regular Interest Certificates.

Notwithstanding the
