This Pooling and Servicing Agreement is dated as of February 1, 2007 (the “Agreement”), among GREENWICH CAPITAL ACCEPTANCE, INC., a Delaware corporation, as depositor (the “Depositor”), GREENWICH CAPITAL FINANCIAL PRODUCTS, INC., a New York corporation, as seller (the “Seller”), XXXXX 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”), XXXXXXX FIXED INCOME SERVICES INC., as credit risk manager (the “Credit Risk Manager”) and DEUTSCHE BANK NATIONAL TRUST COMPANY, a national banking association, as trustee and custodian (the “Trustee”).

PRELIMINARY STATEMENT:

Through this Agreement, the Depositor intends to cause the issuance and sale of the DSLA Mortgage Loan Trust Mortgage Loan Pass-Through Certificates, Series 2007-AR1 (the “Certificates”) representing in the aggregate the entire beneficial ownership of the Trust Fund, 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. The Certificates will consist of sixteen classes of certificates, designated as (i) the Class 1A-1A Certificates, (ii) the Class 2A-1A Certificates, (iii) the Class 2A-1B Certificates, (iv) the Class 2A-1C Certificates, (v) the Class 2A-2C Certificates, (vi) the Class M-1 Certificates, (vii) the Class M-2 Certificates, (viii) Class M-3 Certificates, (ix) the Class M-4 Certificates, (x) the Class M-5 Certificates, (xi) the Class M-6 Certificates, (xii) the Class M-7 Certificates, (xiii) the Class M-8 Certificates, (xiv) the Class M-9 Certificates, (xv) the Class C Certificates, (xvi) the Class P Certificates and (xvii) the Class R Certificates.

For federal income tax purposes, the Trust Fund (exclusive of the assets held in the Prefunding Account, the Capitalized Interest Account, the Basis Risk Reserve Fund, the Basis Risk Cap Agreement, the Basis Risk Cap Account, the Basis Risk Cap Replacement Receipts Account, the Yield Maintenance Trust, the Yield Maintenance Trust Account, the Yield Maintenance Account, the Yield Maintenance Agreement, the Collateral Account, the Final Maturity Reserve Trust and the Final Maturity Reserve Account (the “Excluded Trust Property”)) comprises three REMICs in a tiered REMIC structure: the “Lower-Tier REMIC,” the “Middle-Tier REMIC,” and the “Upper-Tier REMIC.” Each Certificate, other than the Class R Certificates, shall represent ownership of a regular interest in the Upper-Tier REMIC, as described herein. The LIBOR Certificates also represent the right to receive (i) payments in respect of the Final Maturity Reserve Account, (ii) payments in respect of Basis Risk Shortfalls from the Basis Risk Reserve Fund as provided in Section 5.07, (iii) payments in respect of Basis Risk Shortfalls from the Yield Maintenance Account as provided in Section 5.01(h), and (iv) payments in respect of Basis Risk Shortfalls from the Basis Risk Cap Account as provided in Section 5.12. The owners of the Class C Certificates beneficially own the Basis Risk Reserve Fund, the Basis Risk Cap Account, the Final Maturity Reserve Account, the Final Maturity Reserve Trust, the Yield Maintenance Trust Account, and the Yield Maintenance Account. The Class R Certificate represents the sole class of residual interest in the Upper-Tier REMIC, as well as the sole residual interest in each of the Lower-Tier REMIC and the Middle-Tier REMIC.

The Lower-Tier REMIC will hold as its assets all of the assets constituting the Trust Fund (exclusive of the Excluded Trust Property) and will issue five uncertificated interests, four of which shall be the “Lower-Tier Regular Interests” and one residual interest (the “LT-R Interest”), which will represent the sole class of residual interest in the Lower-Tier REMIC.

The Middle-Tier REMIC will hold as its assets all of the Lower-Tier Regular Interests and shall issue 19 uncertificated interests, 18 of which shall be the “Middle-Tier Regular Interests” and one residual interest (the “MT-R Interest”), which will represent the sole class of residual interest in the Middle-Tier REMIC.

The Upper-Tier REMIC will hold as its assets all of the Middle-Tier Regular Interests and shall issue the Certificates.

For purposes of the REMIC Provisions, the startup day for each REMIC created hereby is the Closing Date. All REMIC regular and residual interests created hereby will be retired on or before the Latest Possible Maturity Date.

Lower-Tier REMIC

The following table sets forth (or describes) the designation, interest rate, and initial principal balance of each Lower-Tier Regular Interest and the LT-R Interest:

Designation	Interest Rate	Initial Principal Balance
LT-Initial	(1)	(6)
LT-Subsequent	(2)	(7)
LT-C	(3)	(3)
LT-I	(4)	(4)
LT-R	(5)	(5)

(1)

The interest rate with respect to the first three Distribution Dates (and the related Accrual Period) for the LT- Initial Lower-Tier Regular Interests is a per annum rate equal to the weighted average of the Net Loan Rates of the Initial Mortgage Loans as of the first day of the related Due Period. The interest rate for any subsequent Distribution Date (and the related Accrual Period) is the Net WAC.

(2)	The interest rate with respect to the first three Distribution Dates (and the related Accrual Period) for the LT-Subsequent Lower-Tier Regular Interest is 0.00%, and for every Distribution Date (and related Accrual Period) thereafter is the Net WAC.

(3)

The LT-C Interest is an interest only interest that does not have a principal balance. For the first three Distribution Dates only it shall have a notional balance equal to the aggregate of the Stated Principal Balances, if any, of the Subsequent Mortgage Loans as of the first day of the related Due Period. For the first three Distribution Dates only, it shall be entitled to interest, if any, accrued on the Subsequent Mortgage Loans for the related Due Period at their Net Loan Rates, but only to the extent the interest so accrued is included in Available Funds for either Loan Group for such first Distribution Date. For each Distribution Date after the first three Distribution Dates, the notional balance of the LT-C Interest shall be zero and it shall not be entitled to any distributions.

(4)

The LT-I Interest is an interest only interest that does not have a principal balance but has a notional amount as of any Distribution Date equal to the aggregate of the principal balances of the Mortgage Loans as of the first day of the related Due Period. For any Distribution Date before the Distribution Date in February 2017, it shall bear interest for the related Due Period at a fixed rate of 0.00%, and for each Distribution Date commencing on the Distribution Date in February 2017 and on each Distribution Date thereafter until the Final Maturity Reserve Termination Date, it shall bear interest for the related Due Period at a fixed rate equal to the Final Maturity Reserve Rate.

(5)

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

(6)

The initial principal balance for the LT-Initial Interest shall be equal to the aggregate Stated Principal Balance of the Initial Mortgage Loans as of the Cut-off Date.

(7)

The initial principal balance for the LT-Subsequent Interest shall be equal to the Prefunded Amount.

On each Distribution Date, Available Funds for both Loan Groups shall be distributed among the Lower-Tier Regular Interests and the LT-R Interest in the following order of priority:

(1) First, as interest on the Lower-Tier Regular Interests at the interest rates described above;

(2) Second, to the LT-Initial Interest, in reduction of its principal balance, an amount necessary to cause its principal balance to equal the aggregate of the Stated Principal Balances of the Initial Mortgage Loans as of the close of the related Due Period;

(2) Third, to the LT-Subsequent Interest, in reduction of its principal balance, an amount necessary to reduce its principal balance to zero; and

(3) Finally, to the LT-R Interest, any remaining amounts.

If on any Distribution Date, Realized Losses have been sustained in the related Prepayment Period, and after taking into account distributions on such Distribution Date, the aggregate principal balance of the LT-Initial and LT-Subsequent Interests exceed the Pool Collateral Balance for such Distribution Date, Realized Losses, to the extent of such excess, shall be allocated between the LT-Initial and LT-Subsequent Interests in the same manner in which principal distributions a made on such Lower-Tier Regular Interests.

On each Distribution Date, Net Deferred Interest shall be allocated between the LT-Initial and LT-Subsequent Interests in the same manner in which principal distributions are made on such Lower-Tier Regular Interests.

On each Distribution Date, Prepayment Penalty Amounts on the Initial Mortgage Loans shall be paid in respect of the LT-Initial Interest and any Prepayment Penalty Amounts on the Subsequent Mortgage Loans shall be paid in respect of the LT-Subsequent Interests.

Middle-Tier REMIC

The following table sets forth (or describes) the designation, interest rate, and initial principal balance of each Middle-Tier Regular Interest and the MT-R Interest:

MT-R	(4)	(4)	N/A

(1)

The interest rate with respect to any Distribution Date (and the related Accrual Period) for each of these Middle-Tier Regular Interests is a per annum rate equal to the weighted average of the interest rates on the LT-Initial and LT-Subsequent Lower-Tier Regular Interests, weighted based on their relative principal balances as of the first day of the related Accrual Period.

(2)	The MT-I Interest is an interest only interest that does not have a principal balance. For any Distribution Date, it is entitled to all amounts distributed in respect of the LT-I Interest on such Distribution Date.

(3)	The MT-C Interest is an interest only interest that does not have a principal balance. For any Distribution Date, it is entitled to all amounts distributed in respect of the LT-C Interest on such Distribution Date.

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

(5)	Each of these Middle-Tier Regular Interests shall have an initial principal balance equal to one-half of the Original Class Principal Balance of its Corresponding Class of Certificates.

(6)	The MT-Q Interest shall have an initial principal balance equal to the excess of (i) the Pool Collateral Balance as of the Cut-off Date, over (ii) the aggregate initial class principal amount of each remaining Middle-Tier Regular Interest.

On each Distribution Date, Available Funds shall be distributed in payment of principal on the Lower-Tier Regular Interests as follows:

concurrently to the XX-0X-0X, XX-0X-0X, XX-0X-0X, XX-0X-0X, XX-0X-0X, XX-X-0, MT-M-2, MT-M-3, MT-M-4, MT-M-5, MT-M-6, MT-M-7, MT-M-8, MT-M-9 and MT-P Interests until the principal balance of each such Middle-Tier Regular Interest equals 50% of the Class Principal Balance of the Corresponding Class of Certificates immediately after such Distribution Date;

to the MT-Q Interest until its principal balance equals the excess, if any, of (I) the Pool Collateral Balance immediately after such Distribution Date over (II) the aggregate of the principal balances of the Middle-Tier Regular Interests (other than the MT-Q , MT-C, and the MT-I Interests) after taking into account distributions on such Distribution Date under priority (a) above; and

c.	finally, to the Middle-Tier Regular Interests, as distributions of interest at the interest rates shown in the table above.

On each Distribution Date, after taking into account principal distributions under priorities (a) and (b) above, Realized Losses attributable to principal and any Net Deferred Interest shall each be allocated among the Middle-Tier Regular Interests in the same manner that principal is distributed among such Middle-Tier Regular Interests.

On each Distribution Date, Prepayment Penalty Amounts shall be distributed to the MT-P Interest.

Upper-Tier REMIC

The following table sets forth (or describes) the Class designation, Pass-Through Rate and Original Class Principal Balance for each Class of Certificates, each of which, except for the Class R Certificates, is hereby designated as representing ownership of a REMIC regular interest in the Upper-Tier REMIC for purposes of the REMIC Provisions.

Class	Original Class Principal Balance or Class Notional Balance			Pass-Through Rate

(1)

Calculated pursuant to the definition of “Pass-Through Rate.” For purposes of the REMIC Provisions, for the first Distribution Date only, interest accrued on any Class of LIBOR Certificates at a Pass-Through Rate in excess of the Middle-Tier Net WAC Cap shall be deemed to have been paid from the Basis Risk Reserve Fund, the Yield Maintenance Account, or the Basis Risk Cap Account.

(2)

The Class C Certificates shall have an initial principal balance of $3,994,62116.. The Class C Certificates also comprise a notional component having a notional amount that at all times will equal the aggregate of the principal balances of the Middle-Tier Regular Interests (i.e., the Pool Collateral Balance). For each Distribution Date (and the related Accrual Period), the notional component shall bear interest at a rate equal to the excess of (a) the weighted average of the interest rates on the Middle-Tier Regular Interests (other than the MT-I and MT-C Interests), weighted on the basis of the principal balance of each such Middle-Tier Regular Interest, over (b) the Adjusted Middle-Tier WAC. For any Distribution Date, interest that accrues on the notional component of the Class C Certificates shall be deferred to the extent of any increase in the Overcollateralized Amount on such date. Such deferred interest shall not itself bear interest. In addition to the rights set forth above, the Class C Certificates shall also evidence ownership of the MT-I and MT-C Interests in the Middle-Tier REMIC.

(3)	The Class P Certificates shall not bear interest at a stated rate. The Class P Certificates shall have an initial Class Principal Balance of $100.00. Prepayment Penalty Amounts paid with respect to the Mortgage Loans shall be distributed to the Class P Certificates.

(4)

The Class R Certificates represent the sole class of residual interest in the Upper-Tier REMIC and do not have a principal balance or a pass-through rate. In addition, the Class R Certificates represent ownership of the LT-R Interest in the Lower-Tier REMIC and the MT-R Interest in the Middle-Tier REMIC.

ARTICLE I

DEFINITIONS; DECLARATION OF TRUST

SECTION 1.01. Defined Terms.

Whenever used in this Agreement or in the Preliminary Statement, the following words and phrases, unless the context otherwise requires, shall have the meanings specified in this Article. All calculations of interest described herein shall be made on the basis of an assumed 360-day year consisting of twelve 30-day months unless otherwise indicated in this Agreement.

“Acceptable Successor Servicer”: A FHLMC- or FNMA-approved servicer that is (i) reasonably acceptable to the Master Servicer and (ii) acceptable to each Rating Agency, as evidenced by a letter from each such Rating Agency delivered to the Master Servicer and the Trustee that such entity’s acting as a successor servicer will not result in a qualification, withdrawal or downgrade of the then-current rating of any of the Certificates (without regard to the Certificate Insurance Policy).

“Accepted Master Servicing Practices”: With respect to any Mortgage Loan, as applicable, either (x) those customary mortgage servicing practices of prudent mortgage servicing institutions that master service mortgage loans of the same type and quality as such Mortgage Loan in the jurisdiction where the related Mortgaged Property is located, to the extent applicable to the Trustee (as successor Master Servicer) or the Master Servicer (except in its capacity as successor to the Servicer), or (y) as provided in the Servicing Agreement, to the extent applicable to the Servicers, but in no event below the standard set forth in clause (x).

“Account”: The Distribution Account, the Yield Maintenance Trust Account, the Yield Maintenance Account, the Final Maturity Reserve Account, the Basis Risk Reserve Fund, the Servicing Account, the Prefunding Account, the Capitalized Interest Account or the Policy Account, as the context requires.

“Accrual Period”: With respect to each Distribution Date and the LIBOR Certificates, the period beginning on the immediately preceding Distribution Date (or the Closing Date, in the case of the first Distribution Date) and ending on the day immediately preceding such Distribution Date. Interest for such Classes of LIBOR Certificates will be calculated based upon a 360-day year and the actual number of days in each Accrual Period. With respect to any Distribution Date, the Class C Certificates and each Lower-Tier Regular Interest and each Middle-Tier Regular Interest, the calendar month preceding such Distribution Date. Interest for the Class C Certificates and each Lower-Tier Regular Interest and each Middle-Tier Regular Interest will be calculated based on a 360-day year and assuming each month has 30 days.

“Additional Disclosure Notification”: As defined in Section 3.19(a).

“Additional Form 10-D Disclosure”: As defined in Section 3.19(a).

“Additional Form 10-K Disclosure”: As defined in Section 3.19(b).

SECTION 2.02. Acceptance by Trustee.

The Trustee hereby accepts its appointment as Custodian hereunder and acknowledges the receipt, subject to the provisions of Section 2.01 and subject to the review described below and any exceptions noted on the exception report described in the next paragraph below, of the documents referred to in Section 2.01 above and all other assets included in the definition of “Trust Fund” and declares that, in its capacity as Custodian, it holds and will hold such documents and the other documents delivered to it constituting a Mortgage File, and that it holds or will hold all such assets and such other assets included in the definition of “Trust Fund” in trust for the exclusive use and benefit of all present and future Certificateholders and the Certificate Insurer.

The Trustee (or the Custodian on its behalf) further agrees, for the benefit of the Certificateholders and the Certificate Insurer, to review each Mortgage File delivered to it and to certify and deliver to the Depositor, the Seller, any NIMS Insurer and each Rating Agency an interim certification in substantially the form attached hereto as Exhibit G-2, within 90 days after the Closing Date (or, with respect to any document delivered after the Startup Day, within 45 days of receipt and with respect to any Qualified Substitute Mortgage, within five Business Days after the assignment thereof) that, as to each Mortgage Loan listed in the Mortgage Loan Schedule (other than any Mortgage Loan paid in full or any Mortgage Loan specifically identified in the exception report annexed thereto as not being covered by such certification), (i) all documents required to be delivered by it pursuant to Section 2.01 of this Agreement are in its possession, (ii) such documents have been reviewed by it and have not been mutilated, damaged or torn and relate to such Mortgage Loan and (iii) based on its examination and only as to the foregoing, the information set forth in the Mortgage Loan Schedule that corresponds to items (i), (ii) and (xv) of the Mortgage Loan Schedule accurately reflects information set forth in the Mortgage File. It is herein acknowledged that, in conducting such review, the Trustee and the Custodian on its behalf are under no duty or obligation to inspect, review or examine any such documents, instruments, certificates or other papers to determine that they are genuine, enforceable, or appropriate for the represented purpose or that they have actually been recorded or that they are other than what they purport to be on their face.

No later than 180 days after the Closing Date, the Trustee (or the Custodian on its behalf) shall deliver to the Depositor, any NIMS Insurer and the Seller a final certification in the form annexed hereto as Exhibit G-3 evidencing the completeness of the Mortgage Files, with any applicable exceptions noted thereon.

If, in the process of reviewing the Mortgage Files and making or preparing, as the case may be, the certifications referred to above, the Trustee finds any document or documents constituting a part of a Mortgage File to be missing or not conforming to the requirements set forth herein, at the conclusion of its review the Trustee (or the Custodian as its designated agent) shall promptly notify the Certificate Insurer, the Seller and the Depositor. In addition, upon the discovery by the Seller or the Depositor (or upon receipt by the Trustee of written notification of such breach) of a breach of any of the representations and warranties made by the Seller in the Mortgage Loan Purchase Agreement in respect of any Mortgage Loan that materially adversely affects such Mortgage Loan or the interests of the related Certificateholders or the Certificate Insurer in such Mortgage Loan, the party discovering such breach shall give prompt written notice to the other parties to this Agreement.

The Depositor and the Trustee intend that the assignment and transfer herein contemplated constitute a sale of the Mortgage Loans, the related Mortgage Notes and the related documents, conveying good title thereto free and clear of any liens and encumbrances, from the Depositor to the Trustee and that such property not be part of the Depositor’s estate or property of the Depositor in the event of any insolvency by the Depositor. In the event that such conveyance is deemed to be, or to be made as security for, a loan, the parties intend that the Depositor shall be deemed to have granted and does hereby grant to the Trustee a first priority perfected security interest in all of the Depositor’s right, title and interest in and to the Mortgage Loans, the related Mortgage Notes and the related documents, and that this Agreement shall constitute a security agreement under applicable law.

The Trustee (or the Custodian on its behalf) shall execute and deliver to the Depositor on or prior to each Subsequent Transfer Date an acknowledgment of receipt of the original Mortgage Note (with any exceptions noted), substantially in the form attached as Exhibit G-1 hereto.

The Trustee (or the Custodian on its behalf) shall, for the benefit of the Certificateholders, review each Mortgage File delivered to it for the Subsequent Mortgage Loans and to certify and deliver to the Depositor, the Seller and the Rating Agency an interim certification in substantially the form attached hereto as Exhibit G-2, within 45 days after each Subsequent Transfer Date that, as to each Subsequent Mortgage Loan listed in the Mortgage Loan Schedule (other than any Subsequent Mortgage Loan paid in full or any Subsequent Mortgage Loan specifically identified in the exception report annexed thereto as not being covered by such certification), (i) all documents required to be delivered to it pursuant to Section 2.01 of this Agreement are in its possession, (ii) such documents have been reviewed by it and have not been mutilated, damaged or torn and relate to such Subsequent Mortgage Loan and (iii) based on its examination and only as to the foregoing, the information set forth in the Mortgage Loan Schedule that corresponds to items (i), (ii) and (iii) of the Mortgage Loan Schedule accurately reflects information set forth in the Mortgage File. It is herein acknowledged that, in conducting such review, the Trustee and the Custodian on its behalf are under no duty or obligation to inspect, review or examine any such documents, instruments, certificates or other papers to determine that they are genuine, enforceable, or appropriate for the represented purpose or that they have actually been recorded or that they are other than what they purport to be on their face.

No later than 90 days after each Subsequent Transfer Date, the Trustee or the Custodian on behalf of the Trustee shall deliver to the Depositor and the Seller a final certification in the form annexed hereto as Exhibit G-3 (or a substantially similar form) evidencing the completeness of the Mortgage Files, with any applicable exceptions noted thereon.

If, in the course of such review of the Mortgage Files relating to the Subsequent Mortgage Loans, the Custodian finds any document constituting a part of a Mortgage File which does not meet the requirements of Section 2.01(b), the Trustee shall cause the Custodian to list such as an exception in the Final Certification; provided, however, that the Trustee shall not make any determination as to whether (i) any endorsement is sufficient to transfer all right, title and interest of the party so endorsing, as noteholder or assignee thereof, in and to that Mortgage Note or (ii) any assignment is in recordable form or is sufficient to effect the assignment of and transfer to the assignee thereof under the mortgage to which the assignment relates. The Seller or Originator, as applicable, shall cure any such defect or repurchase or substitute for any such Mortgage Loan in accordance with this Section 2.02.

SECTION 2.03. Repurchase or Substitution of Mortgage Loans by the Originator and the Seller.

(a) Upon its discovery or receipt of written notice of any materially defective document in, or that a document is missing from, a Mortgage File or of the breach by the Originator of any representation, warranty or covenant under the Purchase Agreement in respect of any Mortgage Loan which materially adversely affects the value of that Mortgage Loan or the interest therein of the Certificateholders or the Certificate Insurer, the Trustee shall promptly notify the Originator of such defect, missing document or breach and request that the Originator deliver such missing document or cure such defect or breach within 90 days from the date that the Originator was notified of such missing document, defect or breach, and if the Originator does not deliver such missing document or cure such defect or breach in all material respects during such period, the Trustee shall enforce the Originator’s obligation under the Purchase Agreement and cause the Originator to repurchase that Mortgage Loan from the Trust Fund at the Repurchase Price (as defined in the Purchase Agreement) on or prior to the Determination Date following the expiration of such 90 day period. It is understood and agreed that the obligation of the related Originator to cure or to repurchase or to substitute for (or, with respect to any costs and damages incurred by the Trust Fund in connection with any violation of any anti-predatory or anti-abusive lending laws, indemnify for) any Mortgage Loan as to which a document is missing, a material defect in a constituent document exists or as to which such a breach has occurred and is continuing shall constitute the sole remedy against the Originator respecting such omission, defect or breach available to the Trustee or any NIMS Insurer on behalf of the Certificateholders.

(b) Upon discovery or receipt of written notice that a document does not comply with the requirements of Section 2.01 hereof, or that a document is missing from, a Mortgage File or of the breach by the Seller of any representation, warranty or covenant under the Mortgage Loan Purchase Agreement or in Section 2.04 or Section 2.07 hereof in respect of any Mortgage Loan which materially adversely affects the value of that Mortgage Loan or the interest therein of the Certificateholders or the Certificate Insurer, the Trustee (or the Custodian as its designated agent) shall promptly notify the Seller of such noncompliance, missing document or breach and request that the Seller deliver such missing document or cure such noncompliance or breach within 90 days from the date that the Seller was notified of such missing document, noncompliance or breach, and if the Seller does not deliver such missing document or cure such noncompliance or breach in all material respects during such period, the Trustee shall enforce the Seller’s obligation under the Mortgage Loan Purchase Agreement and cause the Seller to repurchase that Mortgage Loan from the Trust Fund at the Purchase Price on or prior to the Determination Date following the expiration of such 90 day period (subject to Section 2.03(e) below); provided, however, that, in connection with any such breach that could not reasonably have been cured within such 90 day period, if the Seller shall have commenced to cure such breach within such 90 day period, the Seller shall be permitted to proceed thereafter diligently and expeditiously to cure the same within the additional period provided under the Mortgage Loan Purchase Agreement; and, provided further, that, in the case of the breach of any representation, warranty or covenant made by the Seller in Section 2.04 hereof, the Seller shall be obligated to cure such breach or purchase the affected Mortgage Loans for the Purchase Price or, if the Mortgage Loan or the related Mortgaged Property acquired with respect thereto has been sold, then the Seller shall pay, in lieu of the Purchase Price, any excess of the Purchase Price over the Net Liquidation Proceeds received upon such sale.

(c) The Purchase Price or Repurchase Price (as defined in the Purchase Agreement) for a Mortgage Loan purchased or repurchased under this Section 2.03 or such other amount due shall be deposited in the Distribution Account on or prior to the next Determination Date after the Seller’s or the Originator’s obligation to repurchase such Mortgage Loan arises. The Trustee, upon receipt of written certification from the Seller or the Originator of the related deposit in the Distribution Account, shall cause the Custodian to release to the Seller or the Originator, as applicable, the related Mortgage File and shall execute and deliver such instruments of transfer or assignment, in each case without recourse, as the Seller or the Originator, as applicable, shall furnish to it and as shall be necessary to vest in the Seller or the Originator, as applicable, any Mortgage Loan released pursuant hereto and the Trustee and the Custodian shall have no further responsibility with regard to such Mortgage File (it being understood that the Trustee and the Custodian shall have no responsibility for determining the sufficiency of such assignment for its intended purpose). In lieu of repurchasing any such Mortgage Loan as provided above, the Seller may cause such Mortgage Loan to be removed from the Trust Fund (in which case it shall become a Deleted Mortgage Loan) and substitute one or more Qualified Substitute Mortgage Loans in the manner and subject to the limitations set forth in Section 2.03(e) below. It is understood and agreed that the obligation of the Seller to cure or to repurchase or to substitute for (or, with respect to any costs and damages incurred by the Trust Fund in connection with any violation of any anti-predatory or anti-abusive lending laws, indemnify for) any Mortgage Loan as to which a document is missing, a material defect in a constituent document exists or as to which such a breach has occurred and is continuing shall constitute the sole remedy against the Seller respecting such omission, defect or breach available to the Trustee on behalf of the Certificateholders

(d) Notwithstanding anything to the contrary set forth above, with respect to any breach by the Seller of a representation or warranty made by the Seller herein or in the Mortgage Loan Purchase Agreement that materially and adversely affects the value of a Mortgage Loan or the Mortgage Loans or the interest therein of the Certificateholders or the Certificate Insurer, if the Seller would not be in breach of such representation or warranty but for a breach by an Originator of a representation and warranty made by the Originator in the Servicing Agreement, then the Originator thereunder, in the manner and to the extent set forth therein, and not the Seller, shall be required to remedy such breach. In addition to such repurchase or substitution obligation, the Seller shall indemnify the Trust Fund and hold it harmless against any losses, damages, penalties, fines, forfeitures, reasonable and necessary legal fees and related costs, judgments, and other costs and expenses resulting from any claim, demand, defense or assertion based on or grounded upon, or resulting from, a breach of the Seller’s representations and warranties contained in Section 2.04.

The Trustee shall enforce the obligations of the Seller under the Mortgage Loan Purchase Agreement including, without limitation, any obligation of the Seller to purchase a Mortgage Loan on account of missing or defective documentation or on account of a breach of a representation, warranty or covenant as described in this Section 2.03(c).

(e) If pursuant to the provisions of Section 2.03(b), the Seller repurchases or otherwise removes from the Trust Fund a Mortgage Loan that is a MERS Mortgage Loan, the Seller shall take (or shall cause the applicable Servicer to take), at the expense of the Seller (with the cooperation of the Depositor, the Trustee and the Master Servicer), such actions as are necessary either (i) cause MERS to execute and deliver an Assignment of Mortgage in recordable form to transfer the Mortgage from MERS to the Seller and shall cause such Mortgage to be removed from registration on the MERS® System in accordance with MERS’ rules and regulations or (ii) cause MERS to designate on the MERS® System the Seller or its designee as the beneficial holder of such Mortgage Loan.

(f) [Reserved].

(g) Any substitution of Qualified Substitute Mortgage Loans for Deleted Mortgage Loans made pursuant to Section 2.03(a) above must be effected prior to the last Business Day that is within two years after the Closing Date. With respect to any Deleted Mortgage Loan for which the Seller substitutes a Qualified Substitute Mortgage Loan or Loans, such substitution shall be effected by the Seller delivering to the Custodian on behalf of the Trustee, for such Qualified Substitute Mortgage Loan or Loans, the Mortgage Note, the Mortgage, the Assignment to the Trustee, and such other documents and agreements, with all necessary endorsements thereon, as are required by Section 2.01 hereof, together with an Officers’ Certificate stating that each such Qualified Substitute Mortgage Loan satisfies the definition thereof and specifying the Substitution Adjustment (as described below), if any, in connection with such substitution; provided, however, that, in the case of any Qualified Substitute Mortgage Loan that is a MERS Mortgage Loan, the Seller shall provide such documents and take such other action with respect to such Qualified Substitute Mortgage Loans as are required pursuant to Section 2.01 hereof. The Custodian on behalf of the Trustee shall acknowledge receipt for such Qualified Substitute Mortgage Loan or Loans and, within five Business Days thereafter, shall review such documents as specified in Section 2.02 hereof and deliver to the Servicer, with respect to such Qualified Substitute Mortgage Loan or Loans, a certification substantially in the form attached hereto as Exhibit G-2, with any exceptions noted thereon. Within 180 days of the date of substitution, the Custodian on behalf of the Trustee shall deliver to the Seller and the Master Servicer a certification substantially in the form of Exhibit G-3 hereto with respect to such Qualified Substitute Mortgage Loan or Loans, with any exceptions noted thereon. Monthly Payments due with respect to Qualified Substitute Mortgage Loans in the month of substitution are not part of the Trust Fund and will be retained by the Seller. For the month of substitution, distributions to Certificateholders will reflect the collections and recoveries in respect of such Deleted Mortgage Loan in the Due Period preceding the month of substitution and the Depositor or the Seller, as the case may be, shall thereafter be entitled to retain all amounts subsequently received in respect of such Deleted Mortgage Loan. The Seller shall give or cause to be given written notice to the Certificateholders that such substitution has taken place, shall amend the Mortgage Loan Schedule to reflect the removal of such Deleted Mortgage Loan from the terms of this Agreement and the substitution of the Qualified Substitute Mortgage Loan or Loans and shall deliver a copy of such amended Mortgage Loan Schedule to the Trustee, the Master Servicer and the Securities Administrator. Upon such substitution, such Qualified Substitute Mortgage Loan or Loans shall constitute part of the Trust Fund and shall be subject in all respects to the terms of this Agreement and, in the case of a substitution effected by the Seller, the Mortgage Loan Purchase Agreement, including, in the case of a substitution effected by the Seller all representations and warranties thereof included in the Mortgage Loan Purchase Agreement and all representations and warranties thereof set forth in Section 2.04 hereof, in each case as of the date of substitution.

For any month in which the Seller substitutes one or more Qualified Substitute Mortgage Loans for one or more Deleted Mortgage Loans, the Seller shall determine, and provide written certification to the Trustee and the Seller as to, the amount (each, a “Substitution Adjustment”), if any, by which the aggregate Purchase Price of all such Deleted Mortgage Loans exceeds the aggregate, as to each such Qualified Substitute Mortgage Loan, of the principal balance thereof as of the date of substitution, together with one month’s interest on such principal balance at the applicable Net Loan Rate. On or prior to the next Determination Date after the Seller’s obligation to repurchase the related Deleted Mortgage Loan arises, the Seller will deliver or cause to be delivered to the Securities Administrator for deposit in the Distribution Account an amount equal to the related Substitution Adjustment, if any, and the Custodian on behalf of the Trustee, upon receipt of the related Qualified Substitute Mortgage Loan or Loans and a written certification from the Seller of its remittance of the deposit to the Distribution Account, shall release to the Seller the related Mortgage File or Files and shall execute and deliver such instruments of transfer or assignment, in each case without recourse, as the Seller shall deliver to it and as shall be necessary to vest therein any Deleted Mortgage Loan released pursuant hereto.

In addition, the Seller shall obtain at its own expense and deliver to the NIMS Insurer and the Trustee an Opinion of Counsel to the effect that such substitution (either specifically or as a class of transactions) will not cause an Adverse REMIC Event. If such Opinion of Counsel cannot be delivered, then such substitution may only be effected at such time as the required Opinion of Counsel can be given.

(h) Upon discovery by the Seller, the Master Servicer, the Depositor or the Trustee that any Mortgage Loan does not constitute a “qualified mortgage” within the meaning of Section 860G(a)(3) of the Code, the party discovering such fact shall within two Business Days give written notice thereof to the other parties. In connection therewith, the Seller shall repurchase or, subject to the limitations set forth in Section 2.03(e), substitute one or more Qualified Substitute Mortgage Loans for the affected Mortgage Loan within 90 days of the earlier of discovery or receipt of such notice with respect to such affected Mortgage Loan. Any such repurchase or substitution shall be made in the same manner as set forth in Section 2.03(b) above, if made by the Seller. The Trustee shall reconvey to the Seller the Mortgage Loan to be released pursuant hereto in the same manner, and on the same terms and conditions, as it would a Mortgage Loan repurchased for breach of a representation or warranty.

(i) Notwithstanding the foregoing, to the extent that any fact, condition or event with respect to a Mortgage Loan constitutes a breach of both (i) a representation or warranty of the Originator under the Purchase Agreement and (ii) a representation or warranty of the Seller under this Agreement, in each case, which materially adversely affects the value of such Mortgage Loan or the interest therein of the Certificateholders or the Certificate Insurer, the Trustee shall first request that the Originator cure such breach or repurchase such Mortgage Loan and if the Originator fails to cure such breach or repurchase such Mortgage Loan within 60 days of receipt of such request from the Trustee, the Trustee shall then request that the Seller cure such breach or repurchase such Mortgage Loans.

SECTION 2.04. Representations and Warranties of the Seller with Respect to the Mortgage Loans.

The Seller hereby makes the following representations and warranties to the Trustee on behalf of the Certificateholders and the Certificate Insurer as of the Closing Date with respect to the Initial Mortgage Loans and as of the applicable Subsequent Transfer Date with respect to any Subsequent Mortgage Loan:

(i) Any and all requirements of any federal, state or local law including, without limitation, usury, truth in lending, real estate settlement procedures, predatory and abusive lending, consumer credit protection, equal credit opportunity, fair housing or disclosure laws applicable to the origination and servicing of mortgage loans of a type similar to the Mortgage Loans at origination have been complied with;

(ii) No Mortgage Loan is (a)(1) subject to the provisions of the Homeownership and Equity Protection Act of 1994 as amended (“HOEPA”) or (2) has an annual percentage rate (“APR”) or total points and fees that are equal to or exceeds the HOEPA thresholds (as defined in 12 CFR 226.32 (a)(1)(i) and (ii)), (b) a “high cost” mortgage loan, “covered” mortgage loan, “high risk home” mortgage loan, or “predatory” mortgage loan or any other comparable term, no matter how defined under any federal, state or local law, (c) subject to any comparable federal, state or local statutes or regulations, or any other statute or regulation providing for assignee liability to holders of such mortgage loans, or (d) a High Cost Loan or Covered Loan, as applicable (as such terms are defined in the then current Standard & Poor’s LEVELS® Glossary Revised, Appendix E). In addition, no Mortgage Loan originated on or after October 1, 2002, through March 6, 2003, is governed by the Georgia Fair Lending Act;

(iii) With respect to each representation and warranty with respect to any Mortgage Loan made by the Originator in the Purchase Agreement that is made as of the related Closing Date (as defined in the Purchase Agreement), to the Seller’s knowledge, no event has occurred since the related Closing Date (as defined in the Purchase Agreement) that would render such representations and warranties to be untrue in any material respect as of the Closing Date; and

(iv) Each Group 1 Mortgage Loan has an original principal balance that conforms to Xxxxxxx Mac guidelines in effect as of the Closing Date.

With respect to the representations and warranties incorporated in this Section 2.04 that are made to the best of the Seller’s knowledge or as to which the Seller has no knowledge, if it is discovered by the Depositor, the Seller, the Certificate Insurer, the Master Servicer or the Trustee that the substance of such representation and warranty is inaccurate and such inaccuracy materially and adversely affects the value of the related Mortgage Loan or the interest therein of the Certificateholders or the Certificate Insurer then, notwithstanding the Seller’s lack of knowledge with respect to the substance of such representation and warranty being inaccurate at the time the representation or warranty was made, such inaccuracy shall be deemed a breach of the applicable representation or warranty.

It is understood and agreed that the representations and warranties incorporated in this Section 2.04 shall survive delivery of the Mortgage Files to the Trustee and shall inure to the benefit of the Certificateholders and the Certificate Insurer notwithstanding any restrictive or qualified endorsement or assignment. Upon discovery by any of the Depositor, the Seller, the Certificate Insurer, the Master Servicer or the Trustee of a breach of any of the foregoing representations and warranties which materially and adversely affects the value of any Mortgage Loan or the interests therein of the Certificateholders or the Certificate Insurer, the party discovering such breach shall give prompt written notice to the other parties, and in no event later than two Business Days from the date of such discovery. It is understood and agreed that the obligations of the Seller set forth in Section 2.03(a) hereof to cure, substitute for or repurchase (or, with respect to any costs and damages incurred by the trust fund in connection with any violation of any anti-predatory
