            THIS POOLING AND SERVICING AGREEMENT, dated as of February 1, 2006,
among SECURITIZED ASSET BACKED RECEIVABLES LLC, a Delaware limited liability
company, as depositor (the "Depositor"), WELLS FARGO BANK, NATIONAL ASSOCIATION,
a national banking association, as servicer (the "Servicer"), WMC MORTGAGE

                              W I T N E S S E T H:

            In consideration of the mutual agreements herein contained, the
parties hereto agree as follows:

                              PRELIMINARY STATEMENT

            The Trustee shall elect that four segregated asset pools within the
Trust Fund (exclusive of (i) the Prepayment Charges, (ii) the Interest Rate Swap
Agreement and the Cap Agreements, (iii) the Swap Account, (iv) the Excess
Reserve Fund Account, and (v) the right of the LIBOR Certificates to receive
Upper Tier Carry Forward Amounts and, without duplication, Basis Risk Carry
Forward Amounts and the obligation to pay Class IO Shortfalls) be treated for
federal income tax purposes as comprising four REMICs (each, a "Trust REMIC" or,
in the alternative, Pooling Tier REMIC-1, Pooling Tier REMIC-2, the Lower Tier
REMIC and the Upper Tier REMIC, respectively). Each Class of Certificates (other
than the Class P and Class R Certificates), other than the right of each Class
of LIBOR Certificates to receive Upper Tier Carry Forward Amounts and, without
duplication, Basis Risk Carry Forward Amounts and the obligation to pay Class IO
Shortfalls and the right of the Class X Certificates to receive payments from
the Interest Rate Swap Agreement, the Cap Agreements and the Class IO
Shortfalls, represents ownership of a regular interest in the Upper Tier REMIC
for purposes of the REMIC Provisions. The Class R Certificates represent
ownership of the sole class of residual interest in each of Pooling Tier
REMIC-1, Pooling Tier REMIC-2, the Lower Tier REMIC and the Upper Tier REMIC for
purposes of the REMIC Provisions. The Startup Day for each REMIC described
herein is the Closing Date. The latest possible maturity date for each regular
interest is the latest date referenced in Section 2.06.

            The Upper Tier REMIC shall hold as assets the several classes of
uncertificated Lower Tier REMIC Regular Interests, set out below. The Lower Tier
REMIC shall hold as assets the several classes of uncertificated Pooling Tier
REMIC-2 Regular Interests. Pooling Tier REMIC-2 shall hold as assets the several
classes of uncertificated Pooling Tier REMIC-1 Regular Interests. Pooling Tier
REMIC-1 shall hold as assets the assets of the Trust Fund (exclusive of (i) the
Prepayment Premiums, (ii) the Interest Rate Swap Agreement and the Cap
Agreements, (iii) the Swap Account, (iv) the Excess Reserve Fund Account, and
(v) the right of the LIBOR Certificates to receive Upper Tier Carry Forward
Amounts and, without duplication, Basis Risk Carry Forward Amounts and the
obligation to pay Class IO Shortfalls).

            For federal income tax purposes, the Class P Certificates represent
beneficial ownership of the Prepayment Charges, each Class of LIBOR Certificates
represents beneficial ownership of a regular interest in the Upper Tier REMIC
and the right to receive Upper-Tier Carry Forward Amounts and, without
duplication, Basis Risk Carry Forward Amounts, and the Class X Certificates
represent beneficial ownership of two regular interests in the Upper Tier REMIC
and the right to receive payments from the Class IO Shortfalls, the Excess
Reserve Fund Account, the Swap Account, the Interest Rate Swap Agreement and the
Cap Agreements, which portions of the Trust Fund shall be treated as a grantor
trust.

                              Pooling Tier REMIC-1

            Pooling Tier REMIC-1 shall issue the following interests in Pooling
Tier REMIC-1, and each such interest, other than the Class PT1-R Interest, is
hereby designated as a regular interest in the Pooling Tier REMIC-1. Pooling
Tier REMIC-1 Interests with an "I" in their designation shall relate to the
Group I Mortgage Loans and Pooling Tier REMIC-1 Interests with a "II" in their
designation shall relate to the Group II Mortgage Loans. Pooling Tier REMIC-1
shall also issue the Class PT1-R Interest, which shall be represented by the
Class R Certificates. The Class PT1-R Interest is hereby designated as the sole
class of residual interest in Pooling Tier REMIC-1.

(1)    For any Distribution Date (and the related Interest Accrual Period), this
      Pooling-Tier REMIC-2 Regular Interest shall bear interest at a per annum
      rate (its "Pooling-Tier REMIC-2 Interest Rate") equal to the Pooling-Tier
      REMIC-1 Loan Group I WAC Rate.

(2)    For any Distribution Date (and the related Interest Accrual Period), this
      Pooling-Tier REMIC-2 Regular Interest shall bear interest at a per annum
      rate (its "Pooling-Tier REMIC-2 Interest Rate") equal to the weighted
      average of the Pooling-Tier REMIC-1 Interest Rates on the Pooling-Tier
      REMIC-1 Regular Interests relating to the Group I Mortgage Loans and
      having an "A" in their class designation, provided that, on each
      Distribution Date on which interest is distributable on the Corresponding
      Pooling-Tier REMIC-2 IO Interest, this Pooling-Tier REMIC-2 Regular
      Interest shall bear interest at a per annum rate equal to Swap LIBOR
      subject to a maximum rate equal to the weighted average of the
      Pooling-Tier REMIC-1 Interest Rates on the Pooling-Tier REMIC-1 Regular
       Interests relating to the Group I Mortgage Loans and having an "A" in
      their class designation.

(3)    For any Distribution Date (and the related Interest Accrual Period), this
      Pooling-Tier REMIC-2 Regular Interest shall bear interest at a per annum
      rate (its "Pooling-Tier REMIC-2 Interest Rate") equal to the weighted
      average of the Pooling-Tier REMIC-1 Interest Rates on the Pooling-Tier
      REMIC-1 Regular Interests relating to the Group I Mortgage Loans and
      having a "B" in their class designation.

(4)    Each Pooling-Tier REMIC-2 IO Interest is an interest-only interest and
      does not have a principal balance but has a notional balance
      ("Pooling-Tier REMIC-2 IO Notional Balance") equal to the Pooling-Tier
       REMIC-1 Principal Amount of the Corresponding Pooling-Tier REMIC-1 Regular
      Interest. From the Closing Date through and including the Corresponding
      Actual Crossover Distribution Date, each Pooling-Tier REMIC-2 IO Interest
      shall be entitled to receive interest that accrues on the Corresponding
      Pooling-Tier REMIC-1 Regular Interest at a rate equal to the excess, if
      any, of (i) the Pooling-Tier REMIC-1 Interest Rate for the Corresponding
      Pooling-Tier REMIC-1 Regular Interest over (ii) Swap LIBOR. After the
      related Corresponding Actual Crossover Distribution Date, the Pooling-Tier
      REMIC-2 IO Interest shall not accrue interest.

(5)    For any Distribution Date (and the related Interest Accrual Period), this
      Pooling-Tier REMIC-2 Regular Interest shall bear interest at a per annum
      rate (its "Pooling-Tier REMIC-2 Interest Rate") equal to the Pooling-Tier
      REMIC-1 Loan Group II WAC Rate.

(6)    For any Distribution Date (and the related Interest Accrual Period), this
      Pooling-Tier REMIC-2 Regular Interest shall bear interest at a per annum
      rate (its "Pooling-Tier REMIC-2 Interest Rate") equal to the weighted
      average of the Pooling-Tier REMIC-1 Interest Rates on the Pooling-Tier
      REMIC-1 Regular Interests relating to the Group II Mortgage Loans and
      having an "A" in their class designation, provided that, on each
      Distribution Date on which interest is distributable on the Corresponding
      Pooling-Tier REMIC-2 IO Interest, this Pooling-Tier REMIC-2 Regular
      Interest shall bear interest at a per annum rate equal to Swap LIBOR
      subject to a maximum rate equal to the weighted average of the
      Pooling-Tier REMIC-1 Interest Rates on the Pooling-Tier REMIC-1 Regular
      Interests relating to the Group II Mortgage Loans and having an "A" in
      their class designation.

(7)    For any Distribution Date (and the related Interest Accrual Period), this
      Pooling-Tier REMIC-2 Regular Interest shall bear interest at a per annum
      rate (its "Pooling-Tier REMIC-2 Interest Rate") equal to the weighted
      average of the Pooling-Tier REMIC-1 Interest Rates on the Pooling-Tier
      REMIC-1 Regular Interests relating to the Group II Mortgage Loans and
      having a "B" in their class designation.

(8)    The Class PT2-R Interest shall not have a principal balance and shall not
      bear interest.

            On each Distribution Date, the interest distributable in respect of
the Mortgage Loans for such Distribution Date shall be distributed to the
Pooling-Tier REMIC-2 Regular Interests at the Pooling-Tier REMIC-2 Interest
Rates shown above.

            On each Distribution Date, Realized Losses, Subsequent Recoveries
and payments of principal in respect of the Group I Mortgage Loans shall be
allocated to the then outstanding Pooling-Tier REMIC-2 Regular Interests (other
than the Pooling-Tier REMIC-2 IO Interests) relating to the Group I Mortgage
Loans with the lowest numerical denomination until the Pooling-Tier REMIC-2
Principal Amount of such interest is reduced to zero, provided that, for
Pooling-Tier REMIC-2 Regular Interests relating to the Group I Mortgage Loans
with the same numerical denomination, such Realized Losses, Subsequent
Recoveries and payments of principal shall be allocated pro rata between such
Pooling-Tier REMIC-2 Regular Interests, until the Pooling-Tier REMIC-2 Principal
Amount of such interests is reduced to zero.

            On each Distribution Date, Realized Losses, Subsequent Recoveries
and payments of principal in respect of the Group II Mortgage Loans to the
outstanding Pooling-Tier REMIC-2 Regular Interests (other than the Pooling-Tier
REMIC-2 IO Interests) relating to the Group II Mortgage Loans with the lowest
numerical denomination until the Pooling-Tier REMIC-2 Principal Amount of such
interest is reduced to zero, provided that, for Pooling-Tier REMIC-2 Regular
Interests relating to the Group II Mortgage Loans with the same numerical
denomination, such Realized Losses, Subsequent Recoveries and payments of
principal shall be allocated pro rata between such Pooling-Tier REMIC-2 Regular
Interests until the Pooling-Tier REMIC-2 Principal Amount of such interests is
reduced to zero.

                                Lower Tier REMIC

             The Lower-Tier REMIC shall issue the following interests, and each
such interest, other than the Class LT-R Interest, is hereby designated as a
regular interest in the Lower-Tier REMIC. The Class LT-R Interest is hereby
designated as the sole class of residual interest in the Lower-Tier REMIC and
shall be represented by the Class R Certificates.

------------------------

(1)    The interest rate with respect to any Distribution Date for these
      interests is a per annum variable rate equal to the Lower Tier REMIC WAC
      Cap.

(2)    The interest rate with respect to any Distribution Date for the Class
      LT-Group I Interest is a per annum variable rate (expressed as a
      percentage rounded to eight decimal places) equal to the weighted average
      of the pooling-Tier REMIC-2 Interest Rates of the Pooling-Tier REMIC-2
      Regular Interests (other than the Pooling-Tier REMIC-2 IO Interests)
      relating to the Group I Mortgage Loans.

(3)    The interest rate with respect to any Distribution Date for the Class
      LT-Group II Interest is a per annum variable rate (expressed as a
       percentage rounded to eight decimal places) equal to the weighted average
      of the Pooling-Tier REMIC-2 Interest Rates of the Pooling-Tier REMIC-2
      Regular Interests (other than the Pooling-Tier REMIC-2 IO Interests)
      relating to the Group II Mortgage Loans.

(4)    This Lower-Tier Regular Interest is an interest-only interest and does not
      have a Lower-Tier REMIC Principal Amount. On each Distribution Date, this
      Lower-Tier Regular Interest shall be entitled to receive all interest
      distributable on the Pooling-Tier REMIC-2 IO Interests.

(5)    The Class LT-R Interest is the sole class of residual interest in the
      Lower Tier REMIC and it does not have a principal amount or an interest
      rate.

(6)    For all Distribution Dates, the Lower Tier Principal Amount of these Lower
      Tier REMIC Regular Interests shall be rounded to eight decimal places.

            Each Lower Tier REMIC Regular Interest is hereby designated as a
regular interest in the Lower Tier REMIC. The Class LT-A-1A, Class LT-A-1B,
Class LT-A-2A, Class LT-A-2B, Class LT-A-2C, Class LT-M-1, Class LT-M-2, Class
LT-M-3, Class LT-B-1, Class LT-B-2, Class LT-B-3 and Class LT-B-4 Interests are
hereby designated the LT Accretion Directed Classes (the "LT Accretion Directed
Classes").

            On each Distribution Date, 25% of the increase in the Subordinated
Amount shall be payable as a reduction of the Lower Tier REMIC Principal Amount
of the LT Accretion Directed Classes (each such Class will be reduced by an
amount equal to 25% of any increase in the Subordinated Amount that is
attributable to a reduction in the Class Certificate Balance of its
Corresponding Class) and shall be accrued and added to the Lower Tier REMIC
Principal Amount of the Class LT-Accrual Interest. On each Distribution Date,
the increase in the Lower Tier REMIC Principal Amount of the Class LT-Accrual
Interest may not exceed interest accruals for such Distribution Date for the
Class LT-Accrual Interest. All payments of scheduled principal and prepayments
of principal generated by the Mortgage Loans and all Subsequent Recoveries
allocable to principal shall be allocated (i) 25% to the Class LT-Accrual
Interest, (ii) 25% to the LT Accretion Directed Classes (such principal payments
and Subsequent Recoveries shall be allocated among such LT Accretion Directed
Classes in an amount equal to 25% of the principal amounts and Subsequent
Recoveries allocated to their respective Corresponding Classes), until paid in
full and (iii) 50% to Class LT-Group I(SUB) Interest, Class LT-Group I Interest,
Class LT-Group II(SUB) Interest, Class LT-Group II Interest and Class LT-XX
Interest (and further allocated among these Lower Tier REMIC Regular Interests
in the manner described in the next sentence). As among the Class LT-Group
I(SUB) Interest, Class LT-Group I Interest, Class LT-Group II(SUB) Interest,
Class LT-Group II Interest and Class LT-XX Interest, all payments of scheduled
principal and prepayments of principal generated by the Mortgage Loans and
Subsequent Recoveries referred to in clause (iii) of the previous sentence shall
be allocated (i) first, to the Class LT-Group I(SUB) Interest, and Class
LT-Group II(SUB) Interest, each from the related Loan Group, so that their
respective Lower Tier REMIC Principal Amount (computed to at least eight decimal
places) is equal to 0.01% of the related Group Subordinate Amount (except that
if any such amount is a larger number than in the preceding distribution period,
the least amount of principal shall be distributed to the Class LT-Group I(SUB)
Interest and Class LT-Group II(SUB) Interest, as applicable, such that the Lower
Tier REMIC Subordinated Balance Ratio is maintained); (ii) second, to the Class
LT-Group I Interest and the Class LT-Group II Interest 0.01% of the principal
collected in respect of the related Loan Group; and (iii) third, any remaining
amounts of principal shall be distributed to the Class LT-XX Interest.
Notwithstanding the above, principal payments allocated to the Class X Interest
that result in the reduction in the Subordinated Amount shall be allocated (i)
50% to the Class LT-Accrual Interest (until paid in full) and (ii) 50% to the
Class LT-Group I(SUB) Interest, the Class LT-Group II(SUB) Interest, the Class
LT-Group I Interest, the Class LT-Group II Interest and the Class LT-XX Interest
(and allocated among these Lower Tier REMIC Regular Interests in a manner
similar to that described in the immediately preceding sentence).

            Reductions to Lower Tier REMIC Principal Amounts as a result of
Realized Losses and increases in Lower Tier REMIC Principal Amounts as a result
of Subsequent Recoveries shall be applied so that after all distributions have
been made on each Distribution Date (i) the Lower Tier REMIC Principal Amount of
each LT Accretion Directed Class is equal to 25% of the Class Certificate
Balance of its Corresponding Class, (ii) the Class LT-Accrual Interest is equal
to 25% of the aggregate Stated Principal Balance of the Mortgage Loans plus 25%
of the Subordinated Amount, (iii) the Class LT-Group I(SUB) Interest is equal to
0.01% of the Group Subordinate Amount of the Group I Mortgage Loans, (iv) the
Class LT-Group II(SUB) Interest is equal to 0.01% of the Group Subordinate
Amount of the Group II Mortgage Loans, (v) the Class LT-Group I Interest is
equal to 0.01% of the aggregate Stated Principal Balance of the Group I Mortgage
Loans, (vi) the Class LT-Group II Interest is equal to 0.01% of the aggregate
Stated Principal Balance of the Group II Mortgage Loans and (vii) the remainder
shall be applied to the Class LT-XX Interest.

                                Upper-Tier REMIC

            The Upper Tier REMIC shall issue the following classes of Upper Tier
REMIC Regular Interests and each such interest, other than the Class UT-R
Interest, is hereby designated as a regular interest in the Upper Tier REMIC.
The Class UT-R Interest is hereby designated as the sole class of residual
interests in the Upper Tier REMIC and shall be represented by the Class R
Certificates.

(1)    For any Distribution Date (and the related Interest Accrual Period), this
      interest shall bear interest at the lesser of (i) the Pass-Through Rate
      (determined without regard to the Group I Loan Cap) for the Corresponding
      Class of Certificates and (ii) the Lower-Tier Interest Rate for the Class
      LT-Group I Interest (the "Upper-Tier REMIC Loan Group I Rate").

(2)    For any Distribution Date (and the related Interest Accrual Period), this
      interest shall bear interest at the lesser of (i) the Pass-Through Rate
      (determined without regard to the Group II Loan Cap) for the Corresponding
      Class of Certificates and (ii) the Lower-Tier Interest Rate for the Class
      LT-Group II Interest (the "Upper-Tier REMIC Loan Group II Rate").

(3)    For any Distribution Date (and the related Interest Accrual Period), this
      interest shall bear interest at the lesser of (i) the Pass-Through Rate
      (determined without regard to the applicable WAC Cap) for the
      Corresponding Class of Certificates and (ii) the Upper-Tier REMIC Pool Cap
      Rate.

(4)    This interest is an interest-only interest and does not have a principal
      balance. On each Distribution Date, the Class IO Interest shall be
      entitled to receive all interest distributable on the Class LT-IO
      Interest. This interest shall be beneficially owned by the holders of the
       Class X Certificates and shall be held as an asset of the Swap Account.

(5)    The Class X Interest has an initial principal balance of $19,848,085 but
      it will not accrue interest on such balance but will accrue interest on a
      notional principal balance. As of any Distribution Date, the Class X
      Interest shall have a notional principal balance equal to the aggregate of
      the Lower Tier Principal Amounts of the Lower Tier REMIC Regular Interests
      (other than the Class LT-IO Interest) as of the first day of the related
      Interest Accrual Period. With respect to any Interest Accrual Period, the
      Class X Interest shall bear interest at a rate equal to the excess, if
      any, of the Lower Tier REMIC WAC Cap over the product of (i) 2 and (ii)
      the weighted average Lower Tier REMIC Interest Rate of the Lower Tier
      REMIC Regular Interests (other than Class LT-Group I(SUB), Class LT-Group
      I, Class LT-Group II(SUB), Class LT-Group II, Class LT-XX and Class LT-IO
       Interests), where the Lower Tier REMIC Interest Rate on the Class
      LT-Accrual Interest is subject to a cap equal to zero and each
      LT-Accretion Directed Class is subject to a cap equal to the Upper Tier
      Interest Rate on its Corresponding Class of Upper Tier Regular Interest.
      With respect to any Distribution Date, interest that so accrues on the
      notional principal balance of the Class X Interest shall be deferred in an
      amount equal to any increase in the Subordinated Amount on such
      Distribution Date. Such deferred interest shall not itself bear interest.

(6)    The Class UT-R Interest does not have an interest rate or a principal
      balance.

            On each Distribution Date, interest distributable in respect of the
Lower-Tier Interests for such Distribution Date shall be deemed to be
distributed on the interests in the Upper-Tier REMIC at the rates shown above,
provided that the Class IO Interest shall be entitled to receive interest before
any other interest in the Upper-Tier REMIC.

            On each Distribution Date, all Realized Losses, Subsequent
Recoveries and all payments of principal shall be allocated to the Upper-Tier
Interests until the outstanding principal balance of each such interest equals
the outstanding Class Certificate Balance of the Corresponding Class of
Certificates as of such Distribution Date.

      LIBOR plus the applicable Pass-Through Margin and (ii) the Group I Loan
      Cap.

(2)    The Class A-2A Certificates will bear interest during each Interest
      Accrual Period at a per annum rate equal to the lesser of (i) LIBOR plus
      the applicable Pass-Through Margin and (ii) the Group II Loan Cap.

(3)    The Class A-2B Certificates will bear interest during each Interest
      Accrual Period at a per annum rate equal to the lesser of (i) LIBOR plus

(4)    The Class A-2C Certificates will bear interest during each Interest
      Accrual Period at a per annum rate equal to the lesser of (i) LIBOR plus
      the applicable Pass-Through Margin and (ii) the Group II Loan Cap.

(5)    The Class M-1, Class M-2, Class M-3, Class B-1, Class B-2, Class B-3 and
      Class B-4 Certificates will bear interest during each Interest Accrual
      Period at a per annum rate equal to the lesser of (i) LIBOR plus the
      applicable Pass-Through Margin and (ii) the Pool Cap.

(6)    The Class X Certificates will represent beneficial ownership of the Class
      X Interest, the Class IO Interest, the right to receive Class IO
      Shortfalls, the Cap Agreements, amounts in the Swap Account, subject to
      the obligation to pay Net Swap Payments and Upper Tier Carry Forward
      Amounts and, without duplication, Basis Risk Carry Forward Amounts and
      amounts in the Excess Reserve Fund Account, subject to the obligation to
      make payments from the Excess Reserve Fund Account in respect of Basis
      Risk Carry Forward Amounts. For federal income tax purposes, the
      Securities Administrator will treat a Class X Certificateholder's
      obligation to make payments of Upper Tier Carry Forward Amounts and,
      without duplication, Basis Risk Carry Forward Amounts to the LIBOR
      Certificates from the Excess Reserve Fund Account and the Swap Account to
      the LIBOR Certificateholders as payments made pursuant to an interest rate
      cap contract written by the Class X Certificateholders in favor of each
      Class of LIBOR Certificates. Such rights of the Class X Certificateholders
      and LIBOR Certificateholders shall be treated as held in a portion of the
      Trust Fund that is treated as a grantor trust under subpart E, Part I of
      subchapter J of the Code. The Class X Certificates do not have a Class
      Certificate Balance.

(7)    The Class R Certificates do not have a principal balance or an interest
      rate.

(8)    Each of these Certificates will represent not only the ownership of the
      Corresponding Class of Upper Tier REMIC Regular Interest but also the
      right to receive payments from the Excess Reserve Fund Account and Swap
      Account in respect of any Basis Risk Carry Forward Amounts and, without
      duplication, from the Swap Account in respect of Upper Tier Carry Forward
      Amounts. Each of these Certificates will also be subject to the obligation
      to pay Class IO Shortfalls as described in Section 8.13. For federal
      income tax purposes, any amount distributed on the LIBOR Certificates on
      any such Distribution Date in excess of the amount distributable on their
      Corresponding Class of Upper Tier Regular Interest on such Distribution
      Date shall be treated as having been paid from the Excess Reserve Fund
      Account or the Swap Account, as applicable, and any amount distributable
      on such Corresponding Class of Upper Tier Regular Interest on such
      Distribution Date in excess of the amount distributable on the LIBOR
      Certificates on such Distribution Date shall be treated as having been
      paid to the Swap Account, all pursuant to, and as further provided in
      Section 8.13. For federal income tax purposes, the Securities
      Administrator will treat a LIBOR Certificateholder's right to receive
      payments from the Excess Reserve Fund Account and Swap Account as payments
      made pursuant to an interest rate cap contract written by the Class X
      Certificateholders.

            The minimum denomination for each Class of Certificates, other than
the Class P, Class R and the Class X Certificates, will be $25,000 with integral
multiples of $1 in excess thereof except that one Certificate in each Class may
be issued in a different amount. The minimum denomination for each of the Class
P and Class X Certificates will be a 1% Percentage Interest in such Class, and
the minimum denomination for the Class R Certificates shall be 100% Percentage
Interest in such Class.
