            THIS POOLING AND SERVICING AGREEMENT, dated as of March 1, 2006,
among MORGAN STANLEY CAPITAL I INC., a Delaware corporation, as depositor (the
"Depositor"), WELLS FARGO BANK, NATIONAL ASSOCIATION, a national banking
association, as servicer ("the Servicer"), NC CAPITAL CORPORATION, a California
corporation, as responsible party (the "Responsible Party"), and DEUTSCHE BANK
NATIONAL TRUST COMPANY, a national banking association, as trustee (the
"Trustee").

                             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 Premiums, (ii) the Swap Assets,
(iii) the Excess Reserve Fund Account, and (iv) the right of the LIBOR
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 LIBOR
Certificates (other than the right of each Class of LIBOR 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 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 LIBOR 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 LIBOR 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, 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

      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

      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

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

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.

(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-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.

(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 $44,733,872 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.

      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, Basis Risk CarryForward
      Amounts and, without duplication, Upper-Tier CarryForward Amounts. For
      federal income tax purposes, the Trustee 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 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.

(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 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 Trustee 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.
