                  THIS POOLING AND SERVICING AGREEMENT, dated as of April 1,
2006, among MORGAN STANLEY CAPITAL I INC., a Delaware corporation, as depositor
(the "Depositor"), WELLS FARGO BANK, NATIONAL ASSOCIATION, a national banking
association ("Wells Fargo"), as securities administrator (in such capacity, the
"Securities Administrator") and as a servicer and a custodian, JPMORGAN CHASE
BANK, NATIONAL ASSOCIATION, a national banking association, as a servicer
("JPMorgan"), HOMEQ SERVICING CORPORATION, a New Jersey corporation, as a
servicer ("HomEq" and, together with Wells Fargo in its capacity as servicer and
JPMorgan, the "Servicers"), WMC MORTGAGE CORP., a California corporation, as a
responsible party ("WMC"), DECISION ONE MORTGAGE COMPANY, LLC, as a responsible
party ("Decision One"), DEUTSCHE BANK NATIONAL TRUST COMPANY, a national banking
association, as trustee (the "Trustee") and LASALLE BANK NATIONAL ASSOCIATION,
as a custodian ("LaSalle" and, together with Wells Fargo in its capacity as
custodian, the "Custodians").

                              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 Securities Administrator, on behalf of the Trustee, shall
elect that four segregated asset pools within the Trust Fund (exclusive of (i)
the Prepayment Premiums, (ii) the Swap Assets, (iii) the Excess Reserve Fund
Account, and (iv) the right of the Offered Certificates to receive Upper-Tier
CarryForward Amounts including, but without duplication, Basis Risk CarryForward
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). The Class X Interest, Class IO Interest
and each Class of Offered Certificates (other than the right of each Class of
Offered Certificates to receive Upper-Tier CarryForward Amounts including, but
without duplication, Basis Risk CarryForward Amounts and the obligation to pay
Class IO Shortfalls) represents ownership of a regular interest in a REMIC for
purposes of the REMIC Provisions. The Class R Certificates represent ownership
of the sole class of residual interest in each Trust REMIC for purposes of the
REMIC Provisions. The Startup Day for each Trust REMIC described herein is the
Closing Date. The latest possible maturity date for each regular interest is the
latest date referenced in Section 2.05. The Upper-Tier REMIC shall hold as
assets the several classes of uncertificated Lower-Tier 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 Swap Assets,
(iii) the Excess Reserve Fund Account, and (iv) the right of the Offered
Certificates to receive Upper-Tier CarryForward Amounts including, but without
duplication, Basis Risk CarryForward Amounts and the obligation to pay Class IO
Shortfalls).

                   For federal income tax purposes, each Class of Offered
Certificates represents a beneficial ownership of a regular interest in the
Upper-Tier REMIC, the right to receive Upper-Tier CarryForward Amounts
(including, but without duplication, Basis Risk CarryForward Amounts), and the
obligation to pay Class IO Shortfalls; the Class X Certificates represent
beneficial ownership of the Class X Interest, the Class IO Interest, the
Interest Rate Swap Agreement, the Swap Account, the Excess Reserve Fund Account
and the right to receive Class IO Shortfalls, subject to the obligation to pay
Upper-Tier CarryForward Amounts (including, but without duplication, Basis Risk
CarryForward Amounts); and the Class P Certificates represent beneficial
ownership of the Prepayment Premiums, 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
Loan Group I and Pooling Tier REMIC-1 Interests with a "II" in their designation
shall relate to Loan Group II. Pooling-Tier REMIC-1 shall also issue the Class
PT1-R Interest, which is hereby designated as the sole class of residual
interest in Pooling-Tier REMIC-1. The Class PT1-R Interest shall be represented
by the Class R Certificates, shall not have a principal balance and shall have
no interest rate.

(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 Loan Group I 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 Loan Group I 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 Loan Group I and having a "B" in
     their class designation.

(4)   Each Pooling-Tier REMIC-2 IO 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-2 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 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 Loan Group II 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 Loan Group II 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 from the related Loan Group 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
shall be allocated to the then outstanding Pooling-Tier REMIC-2 Regular
Interests (other than the Pooling-Tier REMIC-2 IO Interests) relating to Loan
Group II 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 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 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).

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

(5)   This Lower-Tier Regular Interest is an interest-only interest and does not
     have a Lower-Tier 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.

(6)   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.

                  Each Lower-Tier 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-A-2d, Class LT-M-1, Class LT-M-2, Class LT-M-3,
Class LT-M-4, Class LT-M-5, Class LT-M-6, 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, 50% of the increase in the
Subordinated Amount shall be payable as a reduction of the Lower-Tier Principal
Amount of the LT-Accretion Directed Classes (each such Class will be reduced by
an amount equal to 50% 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 Principal
Amount of the Class LT-Accrual Interest. On each Distribution Date, the increase
in the Lower-Tier Principal Amount of the Class LT-Accrual Interest shall not
exceed interest accruals for such Distribution Date for the Class LT-Accrual
Interest. In the event that: (i) 50% of the increase in the Subordinated Amount
exceeds (ii) interest accruals on the Class LT-Accrual Interest for such
Distribution Date, the excess for such Distribution Date (accumulated with all
such excesses for all prior Distribution Dates) will be added to any increase in
the Subordinated Amount for purposes of determining the amount of interest
accrual on the Class LT-Accrual Interest payable as principal on the
LT-Accretion Directed Classes on the next Distribution Date pursuant to the
first sentence of this paragraph. 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) 50% to the Class
LT-Accrual Interest, the Class LT-Group I Interest and Class LT-Group II
Interest (and further allocated among these Lower-Tier Regular Interests in the
manner described below) and (ii) 50% 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 50% of the principal amounts
and Subsequent Recoveries allocated to their respective Corresponding Classes),
until paid in full. Notwithstanding the above, principal payments allocated to
the Class X Interest that result in the reduction in the Subordinated Amount
shall be allocated to the Class LT-Accrual Interest (until paid in full).
Realized Losses shall be applied so that after all distributions have been made
on each Distribution Date (i) the Lower-Tier Principal Amount of each of the
LT-Accretion Directed Classes is equal to 50% of the Class Certificate Balance
of their Corresponding Class, and (ii) the Class LT-Accrual Interest, the Class
LT-Group I Interest and the Class LT-Group II Interest (and further allocated
among these Lower-Tier Regular Interests in the manner described below) is equal
to 50% of the aggregate Stated Principal Balance of the Mortgage Loans plus 50%
of the Subordinated Amount. Any increase in the Class Certificate Balance of a
Class of Offered Certificates as a result of a Subsequent Recovery shall
increase the Lower-Tier Principal Amount of the Corresponding Lower-Tier Regular
Interest by 50% of such increase, and the remaining 50% of such increase shall
increase the Lower-Tier Principal Amount of the Class LT-Accrual Interest, the
Class LT-Group I Interest and the Class LT-Group II Interest (such increase
shall be further allocated among such Lower-Tier Regular Interests in the manner
described below). As among the Class LT-Accrual Interest, the Class LT-Group I
Interest and the Class LT-Group II Interest, all payments of scheduled principal
and prepayments of principal generated by the Mortgage Loans, all Subsequent
Recoveries and all Realized Losses, allocable to such Lower-Tier Regular
Interests and all increases in the Lower-Tier Principal Amount of such
Lower-Tier Regular Interests as a result of Subsequent Recoveries shall be
allocated (i) to the Class LT-Group I Interest and the Class LT-Group II
Interest, each from the related Loan Group so that their respective Lower-Tier
Principal Amounts (computed to at least eight decimal places) are equal to
0.001% of the aggregate Stated Principal Balance of the Mortgage Loans in the
related Loan Group and (ii) the remainder to the Class LT-Accrual Interest.

                                Upper-Tier REMIC

                  The Upper-Tier REMIC shall issue the following 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 least of (i) the Pass-Through Rate
     (determined without regard to the Loan Group I Cap or WAC Cap) for the
     Corresponding Class of Certificates, (ii) the Lower-Tier Interest Rate for
     the Class LT-Group I Interest (the "Upper-Tier REMIC Loan Group I Rate")
     and (ii) the Upper-Tier REMIC WAC Rate.

(2)   For any Distribution Date (and the related Interest Accrual Period) this
     interest shall bear interest at the least of (i) the Pass-Through Rate
     (determined without regard to the Loan Group II Cap or WAC Cap) for the
     Corresponding Class of Certificates, (ii) the Lower-Tier Interest Rate for
     the Class LT-Group II Interest (the "Upper-Tier REMIC Loan Group II Rate")
     and (ii) the Upper-Tier REMIC WAC 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 WAC Cap) for the Corresponding Class of
     Certificates and (ii) the Upper-Tier REMIC WAC 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 $79,340,639 but
     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 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
     Upper-Tier REMIC WAC Rate over the product of (i) 2 and (ii) the weighted
     average of the Lower-Tier Interest Rates of the Lower-Tier REMIC Interests
     (other than the Class LT-IO Interest), where the Lower-Tier Interest Rate
      on each of the Class LT-Accrual Interest, Class LT-Group I Interest and
     Class LT-Group II 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.

(6)   The Class M-1, Class M-2, Class M-3, Class M-4, Class M-5, Class M-6, Class
     B-1, Class B-2 and Class B-3 Interests will bear interest during each
     Interest Accrual Period at a per annum rate equal to (a) on or prior to the
     Optional Termination Date, the lesser of (i) LIBOR plus the applicable
     Pass-Through Margin, and (ii) the WAC Cap or (b) after the Optional
     Termination Date, the lesser of (i) LIBOR plus the applicable Pass-Through
     Margin, and (ii) the WAC Cap.

(7)   The Class X Certificates will represent beneficial ownership of the Class X
     Interest, the Class IO Interest, the Interest Rate Swap Agreement, the
     right to Class IO Shortfalls and amounts in the Excess Reserve Fund Account
     and the Swap Account, subject to the obligation to make payments from the
     Excess Reserve Fund Account in respect of Basis Risk CarryForward Amounts
     and amounts in the Swap Account subject to the obligation to make Net Swap
     Payments, Swap Termination Payments and Basis Risk CarryForward Amounts
     and, without duplication, Upper Tier Carryforward Amounts. For federal
     income tax purposes, the Securities Administrator will treat a Class X
     Certificateholder's obligation to make payments from the Excess Reserve
     Fund Account or the Swap Account as payments made pursuant to an interest
     rate cap contract written by the Class X Certificateholders in favor of
     each Class of Offered Certificates. Such rights of the Class X
     Certificateholders and Offered 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.

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

(9)   Each of these Certificates will represent not only the ownership of the
     Corresponding Class of Upper-Tier Regular Interest but also the right to
     receive payments from the Excess Reserve Fund Account and the Swap Account
     in respect of any Basis Risk CarryForward Amounts and, without duplication,
     Upper Tier CarryForward 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 Offered 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 Offered 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 Certificateholder's right to receive
     payments from the Excess Reserve Fund Account or the 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. The minimum denomination for the
Class P and the Class X Certificates will each be a 1% Percentage Interest in
such Class. The Class R Certificate will represent a 100% Percentage Interest in
such Class.

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