            THIS POOLING AND SERVICING AGREEMENT, dated as of August 1, 2005,

among MORGAN STANLEY ABS CAPITAL I INC., a Delaware corporation (the

"Depositor"), COUNTRYWIDE HOME LOANS SERVICING LP, a Texas limited partnership

("Countrywide"), HOMEQ SERVICING CORPORATION, a New Jersey corporation ("HomEq",

and together with Countrywide, the "Servicers"), WMC MORTGAGE CORP., a

California corporation ("WMC"), ACCREDITED HOME LENDERS, INC., a California

corporation ("Accredited"), DECISION ONE MORTGAGE COMPANY LLC, a California

limited liability company ("Decision One"), WELLS FARGO BANK, NATIONAL

ASSOCIATION, a national banking association, as trustee (in such capacity, the

"Trustee") and custodian (in such capacity, "Wells Fargo"), LASALLE BANK

NATIONAL ASSOCIATION, a national banking association, as custodian ("LaSalle"),

and DEUTSCHE BANK NATIONAL TRUST COMPANY, a national banking association, as

custodian ("Deutsche Bank" and, together with Wells Fargo and LaSalle, 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 Trustee shall elect that four segregated asset pools within the

Trust Fund (exclusive of (i) the Prepayment Premiums, (ii) the Interest Rate

Swap Agreement, (iii) the Swap Account, (iv) the Excess Reserve Fund Account,

and (v) 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 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 Certificate 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 Interest Rate Swap Agreement, (iii) the Swap

Account, (iv) the Excess Reserve Fund Account, and (v) 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)    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-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 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 $32,790,501 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

      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

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.

      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 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
