Representations and Warranties – Mortgage Loans

This Pooling and Servicing Agreement is dated as of July 1, 2005 (the “Agreement”), among GREENWICH CAPITAL ACCEPTANCE, INC., a Delaware corporation, as depositor (the “Depositor”), GREENWICH CAPITAL FINANCIAL PRODUCTS, INC., a Delaware corporation, as seller (the “Seller”), WELLS FARGO BANK, N.A., a national banking association, as master servicer (in such capacity, the “Master Servicer”) and as securities administrator (in such capacity, the “Securities Administrator”) and DEUTSCHE BANK NATIONAL TRUST COMPANY, a national banking association, as trustee (the “Trustee”).

PRELIMINARY STATEMENT:

Through this Agreement, the Depositor intends to cause the issuance and sale of the DSLA Mortgage Loan Trust 2005-AR5 DSLA Mortgage Pass-Through Certificates, Series 2005-AR5 (the “Certificates”) representing in the aggregate the entire beneficial ownership of the Trust, the primary assets of which are the Mortgage Loans (as defined below).

The Depositor intends to sell the Certificates to be issued hereunder in multiple classes, which in the aggregate will evidence the entire beneficial ownership interest in the Trust Fund created hereunder. The Certificates will consist of sixteen classes of certificates, designated as (i) the Class 1-A1A Certificates, (ii) the Class 1-A1B Certificates, (iii) the Class 2-A1A Certificates, (iv) the Class 2-A1B Certificates, (v) the Class X-1 Certificates, (vi) the Class X-2 Certificates, (vii) the Class PO Certificates (viii) the Class A-R Certificate, (ix) the Class B-1 Certificates, (x) the Class B-2 Certificates, (xi) the Class B-3 Certificates, (xii) the Class B-4 Certificates, (xiii) the Class B-5 Certificates, (xiv) the Class B-6 Certificates, (xv) the Class B-7 Certificates and (xvi) the Class A-R-II Certificate. As provided herein, the Trustee shall elect that the Trust Fund (exclusive of the assets held in the Basis Risk Reserve Fund, the Yield Maintenance Account, and the Yield Maintenance Agreements) be treated for federal income tax purposes as comprising three real estate mortgage investment conduits (each, a “REMIC” or, in the alternative, the “Lower-Tier REMIC,” the “Middle-Tier REMIC,” and the “Upper-Tier REMIC”). Each Certificate, other than the Class A-R and Class A-R-II Certificates, shall represent ownership of a regular interest in the Upper-Tier REMIC, as described herein. In addition, the Class 1-A1A, Class 1-A1B, Class 2-A1A, Class 2-A1B, Class B-1, Class B-2, Class B-3, Class B-4, Class B-5, Class B-6, and Class B-7 Certificates represent the right to receive payments in respect of Basis Risk Shortfalls. The Class X-2 Certificates, in addition to representing beneficial ownership of REMIC regular interests, also represent beneficial ownership of the Basis Risk Reserve Fund and the Yield Maintenance Account. The Class A-R Certificate represents the ownership of the sole residual interest in each of the Middle-Tier REMIC and the Upper-Tier REMIC. The Class A-R-II Certificate represents ownership of the sole class of residual interest in the Lower-Tier REMIC.

The Lower-Tier REMIC shall hold as assets all property of the Trust Fund other than the assets held in the Basis Risk Reserve Fund, the Yield Maintenance Account, the Yield Maintenance Agreements, and the interests in any REMIC formed hereby. The Middle-Tier REMIC shall hold as assets the uncertificated Lower-Tier Interests in the Lower-Tier REMIC, other than the Class LT-R Interest, and each such Lower-Tier Interest is hereby designated as a regular interest in the Lower-Tier REMIC. The Upper-Tier REMIC shall hold as assets the uncertificated Middle-Tier Interests in the Middle-Tier REMIC, other than the Class MT-R Interest, and each such Middle-Tier Interest is hereby designated as a regular interest in the Middle-Tier REMIC.

(1)

The interest rate with respect to any Distribution Date (and the related Accrual Period) for each of these Lower-Tier Interests is a per annum rate equal to the Net WAC for Loan Group 1.

(2)

The interest rate with respect to any Distribution Date (and the related Accrual Period) for each of these Lower-Tier Interests is a per annum rate equal to the Net WAC for Loan Group 2.

(3)

The Class LT-R Interest is the sole class of residual interest in the Lower-Tier REMIC. It does not have a principal balance or an interest rate.

On each Distribution Date, Available Funds for Loan Group 1 shall be allocated in the following order of priority:

(i)

to the LT-R, LT-A1 and the LT-X1-1 through LT-X1-42 Interests as principal distributions until the aggregate balance of such Lower-Tier Interests equals the Loan Group Balance for Loan Group 1 immediately prior to such Distribution Date; amounts distributable pursuant to this priority shall be distributed first to the LT-A1 Interest until its principal balance is reduced to zero, and then to each of the LT-X1-1 through LT-X1-42 Interests in ascending order of their numerical designation until the principal balance of each such Lower-Tier Interest is reduced to zero.

(ii)

to the LT-R, LT-A1 and the LT-X1-1 through LT-X1-42 Interests, interest at the interest rates described above, provided, however, to the extent there is any Net Deferred Interest on the Mortgage Loans in Loan Group 1, interest accrued on the LT-A1 and LT-X1-1 through LT-X1-42 Interests shall be deferred and such deferrals shall occur in the same order and priority in which the principal is distributed among such Lower-Tier Interests under priority (i) above.

On each Distribution Date, Available Funds for Loan Group 2 shall be allocated in the following order of priority:

(i)

to the LT-A2 and the LT-X2-1 through LT-X2-42 Interests as principal distributions until the aggregate balance of such Lower-Tier Interests equals the Loan Group Balance for Loan Group 2 immediately prior to such Distribution Date; amounts distributable pursuant to this priority shall be distributed first to the LT-A2 Interest until its principal balance is reduced to zero, and then to each of the LT-X2-1 through LT-X2-42 Interests in ascending order of their numerical designation until the principal balance of each such Lower-Tier Interest is reduced to zero.

(ii)

to the LT-A2 and the LT-X2-1 through LT-X2-42 Interests, interest at the interest rates described above, provided, however, to the extent there is any Net Deferred Interest on the Mortgage Loans in Loan Group 2, interest accrued on the LT-A2 and LT-X2-1 through LT-X2-42 Interests shall be deferred and such deferrals shall occur in the same order and priority in which the principal is distributed among such Lower-Tier Interests under priority (i) above.

Realized Losses shall be allocated among the Lower-Tier Interests in the same order and priority in which principal is distributable on the Lower-Tier Interests.

On each Distribution Date, the Securities Administrator shall be deemed to have distributed the Prepayment Penalties collected during the preceding Prepayment Period with respect to Pool 1 and Pool 2, in the case of Principal Prepayments in full, or during the related Collection Period, in the case of Principal Prepayments in part, to the Class LT-X1-42 and Class LT-X2-42 Lower Tier Interests, respectively.

__________________________

(1)

The interest rate with respect to any Distribution Date (and the related Accrual Period) for each of these Middle-Tier Interests is a per annum rate equal to the weighted average of the interest rates on the Lower-Tier Interests having an “X” in their designation, weighted on the basis of their principal balances as of the first day of the related Accrual Period, provided, however, that for any Distribution Date on which the MTX1-IO-1 or MTX1-IO-2 Interests are entitled to a portion of the interest accruals on a Lower-Tier Interest having an “X” in its designation, as described in footnotes four and five, below, such weighted average shall be computed by first reducing the interest rate on such Lower-Tier Interest by 1.00%.

(2)

(3)

The interest rate with respect to any Distribution Date (and the related Accrual Period) for each of these Middle-Tier Interests is a per annum rate equal to the weighted average of the interest rates on all of the Lower-Tier Interests, other than the LT-R Interests, weighted on the basis of their principal balances as of the first day of the related Accrual Period, provided, however, that for any Distribution Date on which the MTX1-IO-1 or MTX1-IO-2 Interests are entitled to a portion of the interest accruals on a Lower-Tier Interest having an “X” in its designation, as described in footnotes four and five, below, such weighted average shall be computed by first reducing the interest rate on such Lower-Tier Interest by 1.00%.

(4)

The MTX1-IO-1 Interest is an interest only interest that does not have a principal balance. For only those Distribution Dates listed in the first column in the table below, the MTX1-IO-1 shall be entitled to interest accrued on the Lower-Tier Interest listed in second column in the table below at a per annum rate equal to 1.00%.

The Class MT-R Interest is the sole class of residual interests in the Middle-Tier REMIC. It does not have an interest rate or a principal balance.

On each Distribution Date, all amounts distributable with respect to the Lower-Tier Interests shall be allocated among the Middle-Tier Interests interest, and Realized Losses shall be allocated among the Middle Tier Interests, in the following order of priority:

(iii)

First, to the MTZ and the MTY Interests in reduction of their principal balances as follows –

(a)

To the MTZ Interest the amount, if any, required to reduce its principal balance to the MTZ Target Balance for such Distribution Date;

(b)

To the MTY Interest the amount, if any, required to reduce its principal balance to the MTY Target Balance for such Distribution Date;

(c)

To the MTZ and MTY Interest in proportion to their principal balances, after taking into account distributions pursuant to priorities (a) and (b) above, until the sum of their principal balances equals 2% of the Pool Balance immediately after such Distribution Date;

(iv)

Second, concurrently to the MT1-A1A, MT1-A1B, MT2-A1A, MT2-AIB, MTB-1, MTB-2, MTB-3, MTB-4, MTB-5, MYB-6, and MTB-7 Interests until the principal balance of each such Middle-Tier Interest equals 50% of the Class Certificate Balances of the Corresponding Class or Classes of Certificates for such Middle-Tier Interests immediately after such Distribution Date;

(v)

Third, to the MTQ Interest, until its principal balance equals the excess of (a) the Pool Balance immediately after such Distribution Date over (b) the aggregate of the principal balances of the other Lower-Tier Interests after taking into account the distributions made pursuant to priorities (i) and (ii) above on such Distribution Date;

(vi)

Fourth, remaining amounts shall be applied to interest distributions on the Middle-Tier Interests at the interest rates described above, provided, however, that any Net Deferred Interest on the Mortgage Loans will be allocated among and increase the principal balances of the Middle-Tier Interests in the same order of priority in which principal is distributed among the Middle-Tier Interests pursuant to priorities (i)(c), (ii), and (iii) above.

The Class X-1 Certificates will be deemed for purposes of the distribution of interest to consist of two Components: the X-1 IO-1 Component and the X-1 IO-2 Component. The Components are not severable. The Class X-1 Certificates are not entitled to distributions of principal. For purposes of the REMIC Provisions, the Class X-1 Certificates shall be entitled on each Distribution Date to 100% of the amounts distributable on the MTX1-IO-1 and MTX1-IO-2 Interests.

(3)

For purposes of the REMIC provisions, the Class X-2 Certificates shall accrue interest on a notional balance equal to the sum of the principal balances of the Middle-Tier Interests (other than the MT-R, MTX1-IO-1, and MTX1-IO-2 Interests). For purposes of the REMIC Provisions, interest shall accrue on the Class X-2 Certificate at a rate equal to the excess, if any, of (i) the product of (a) the weighted average of the interest rates on the MTZ and MTY Interests immediately after such Distribution Date, computed for this purpose by subjecting the interest rate on the MTY Interest to a cap of 0.00%, multiplied by (b) two, over (ii) the Adjusted Middle-Tier WAC. The Class X-2 Certificates are interest-only certificates and will not be entitled to distributions of principal.

(4)

The Class PO Certificates will be deemed for purposes of the distribution of principal to consist of two components: the PO-1 Component and the PO-2 Component. The Components are not severable. For purposes of the REMIC Provisions, the Class PO Certificates shall accrue interest on a notional balance equal to the sum of the principal balances of the Middle-Tier Interests (other than the MT-R, MTX1-IO-1, and MTX1-IO-2 Interests). For purposes of the REMIC Provisions, interest shall accrue on the Class PO Certificates at a rate equal to the excess of (i) the weighted average of the interest rates for the related Accrual Period on the Middle-Tier Interests (other than the MT-R, MTX1-IO-1, and the MTXI-IO-2 Interests) over (ii) the Adjusted Middle-Tier Pay Rate. Any interest accrued on the Class PO Certificates will not be paid currently but shall increase the Component Principal Balances of the Class PO-1 and Class PO-2 Components in proportion to the amount of interest deferred on the related Loan Group.

(5)

The Class PO Certificate is a principal-only certificates and will not be entitled to distributions of interest.

(6)

Calculated pursuant to the definition of “Pass-Through Rate”, but adjusted, for purposes of the REMIC Provisions, to reflect the allocation, if any, of Subordinate Class Expense Share.

(7)

For purposes of the REMIC Provisions, the Class A-R Certificate represents the sole class of residual interest in the Upper-Tier REMIC as well as ownership of the MT-R Interests.

(8)

For purposes of the REMIC Provisions, the Class A-R-II Certificate represents ownership of the Class LT-R Interest, which is the sole class of residual interest in the Lower-Tier REMIC, and which does not have a principal balance or an interest rate.
