            THIS POOLING AND SERVICING AGREEMENT, dated as of November 1, 2006,
among SECURITIZED ASSET BACKED RECEIVABLES LLC, a Delaware limited liability
company, as depositor (the "Depositor"), BARCLAYS CAPITAL REAL ESTATE INC.,
D/B/A HOMEQ SERVICING, a Delaware corporation, as servicer (the "Servicer"),
FREMONT INVESTMENT & LOAN, a California industrial bank, as responsible party
(the "Responsible Party"), DEUTSCHE BANK NATIONAL TRUST COMPANY, a national
banking association, as trustee (the "Trustee") and WELLS FARGO BANK, NATIONAL
ASSOCIATION, a national banking association, as custodian (the "Custodian").

                              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 Agreement, (iii) the Supplemental Interest Account, (iv)
the Excess Reserve Fund Account, and (v) the right of the LIBOR Certificates to
receive Basis Risk Carry Forward Amounts and, without duplication, Upper-Tier
Carry Forward Amounts, subject to 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 Certificates and the Residual
Certificates), other than the right of each Class of LIBOR Certificates to
receive Basis Risk Carry Forward Amounts and, without duplication, Upper-Tier
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 Agreement and the right to receive Class IO Shortfalls,
represents ownership of a regular interest in the Upper-Tier REMIC for purposes
of the REMIC Provisions. The Class R-I Certificates represent ownership of the
sole class of residual interest in Pooling Tier REMIC-1 for purposes of the
REMIC Provisions. The Class R-II Certificates represent ownership of the sole
class of residual interest in each of Pooling Tier REMIC-2, the Lower-Tier REMIC
and the Upper-Tier REMIC for purposes of the REMIC Provisions. The Startup Day
for each Trust REMIC 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
Agreement, (iii) the Supplemental Interest Account, (iv) the Excess Reserve Fund
Account, (v) the Cap Agreement and (vi) the right of the LIBOR Certificates to
receive Basis Risk Carry Forward Amounts and, without duplication, Upper-Tier
Carry Forward Amounts, subject to 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 Basis Risk Carry Forward Amounts and, without
duplication, Upper-Tier Carry Forward Amounts, subject to the obligation to pay
Class IO Shortfalls, and the Class X Certificates represent beneficial ownership
of two regular interests in the Upper-Tier REMIC, the Excess Reserve Fund
Account, the Supplemental Interest Account, the Interest Rate Swap Agreement,
the Cap Agreement and the right to receive Class IO Shortfalls, 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 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 R-I Certificates. The Class PT1-R Interest is hereby
designated as the sole class of residual interest in Pooling Tier REMIC-1.

(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

      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.

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

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 (including,
for the first Distribution Date only, the portion of the Closing Date Deposit
Amount allocable to 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 or interests, as the case may be, is reduced to zero, provided that,
for Pooling Tier REMIC-2 Regular Interests 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 (including,
for the first Distribution Date only, the portion of the Closing Date Deposit
Amount allocable to the Group II Mortgage Loans) shall be allocated 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.

      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-1, 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-M-4,
Class LT-M-5, Class LT-B-1, Class LT-B-2 and Class LT-B-3 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 (including, for the first
Distribution Date only, the Closing Date Deposit Amount) 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-II
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 Pool 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 Supplemental
      Interest Account.

(5)    The Class X Interest has an initial principal balance of $22,151,634 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 Rate 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.

(1)    The Class A-1 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 I Loan Cap.

(2)    The Class A-2A, Class A-2B and 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.

(3)    The Class M-1, Class M-2, Class M-3, Class M-4, Class M-5, Class B-1,
      Class B-2 and Class B-3 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.

(4)    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 Agreement, the Interest Rate Swap Agreement, amounts
      in the Supplemental Interest Account, subject to the obligation to pay Net
      Swap Payments to the Swap Provider and Basis Risk Carry Forward Amounts
      and, without duplication, Upper-Tier Carry Forward Amounts to the LIBOR
      Certificates. For federal income tax purposes, the Trustee will treat a
      Class X Certificateholder's obligation to make payments to the LIBOR
      Certificates of Basis Risk Carry Forward Amounts from the Excess Reserve
      Fund Account and the Supplemental Interest Account and, without
      duplication, Upper-Tier Carry Forward Amounts from the Supplemental
      Interest Account and the right to receive Class IO Shortfalls as payments
      made pursuant to a notional principal contract between the Class X
      Certificateholders and the holder 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.

(5)    The Class R-I Certificates do not have a principal balance or an interest
      rate. The Class R-I Certificates represent the residual interest in
      Pooling Tier REMIC-1.

(6)    The Class R-II Certificates do not have a principal balance or an interest
      rate. The Class R-II Certificates represent ownership of the Class PT2-R
      Interest, the Class LT-R Interest and the Class UT-R Interest.

(7)    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
      Supplemental Interest Account in respect of any Basis Risk Carry Forward
      Amounts and, without duplication, from the Supplemental Interest 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 Supplemental
      Interest 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 Corresponding Class of
       Certificates on such Distribution Date shall be treated as having been
      paid to the Supplemental Interest Account, all pursuant to, and as further
      provided in Section 8.13. For federal income tax purposes, the Trustee
      will treat a LIBOR Certificateholder's right to receive payments from the
      Excess Reserve Fund Account and Supplemental Interest Account subject to
      the obligation to pay Class IO Shortfalls as payments made pursuant to a
      notional principal contract between the Class X Certificateholders and
      each Class of LIBOR Certificates.

            The minimum denomination for each Class of Certificates, other than
the Class P and Class X Certificates and the Residual 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 Residual
Certificates shall be 100% Percentage Interest in such Class.

            It is expected that each Class of Certificates will receive its
final distribution on or prior to the applicable Final Scheduled Distribution
Date.
