Schedule I

Mortgage Loan Schedule

This Pooling Agreement is dated as of April 1, 2006 (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”) and U.S. BANK NATIONAL ASSOCIATION, a national banking association, as trustee (the “Trustee”).

PRELIMINARY STATEMENT:

Through this Agreement, the Depositor intends to cause the issuance and sale of the HarborView Mortgage Loan Trust 2006-4 Mortgage Loan Pass-Through Certificates, Series 2006-4 (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 thirty classes of certificates, designated as (i) the Class 1-A1A Certificates, (ii) the Class 1-A1B Certificates, (iii) the Class 1-A2A Certificates, (iv) the Class 1-A2B Certificates, (v) the Class 2-A1A Certificates, (vi) the Class 2-A1B Certificates, (vii) the Class 2-A1C Certificates, (viii) the Class 3-A1A Certificates, (ix) the Class 3-A1B Certificates, (x) the Class 3-A1C Certificates, (xi) the Class X-1 Certificates, (xii) the Class X-3A Certificates, (xiii) the Class X-B Certificates, (xiv) the Class PO-1 Certificates, (xv) the Class PO-3A Certificates, (xvi) the Class PO-B Certificates, (xvii) the Class A-R Certificates, (xviii) the Class B-1 Certificates, (xix) the Class B-2 Certificates, (xx) the Class B-3 Certificates, (xxi) the Class B-4 Certificates, (xxii) the Class B-5 Certificates, (xxiii) the Class B-6 Certificates, (xxiv) the Class B-7 Certificates, (xxv) the Class B-8 Certificates, (xxvi) the Class B-9 Certificates, (xxvii) the Class B-10 Certificates, (xxviii) the Class B-11 Certificates, (xxix) the Class B-12 Certificates and (xxx) the Class A-R-II Certificates.

As provided herein, the Trustee shall elect that the Trust Fund (exclusive of the assets held in the Basis Risk Reserve Fund) 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 LIBOR Certificates represent the right to receive payments in respect of Basis Risk Shortfalls from the Basis Risk Reserve Fund as provided in Section 5.07. The owners of the Class X-1, Class X-3A and Class X-B Certificates beneficially own the Basis Risk Reserve Fund. The Class A-R-II Certificate represents ownership of the sole class of residual interest in the Lower-Tier REMIC, and the Class A-R Certificates represent ownership of the sole class of residual interest in the Middle-Tier and the Upper-Tier REMICs.

The Lower-Tier REMIC shall hold as assets all property of the Trust Fund, other than the Basis Risk Reserve Fund and the Lower-Tier REMIC Interests and the Middle-Tier REMIC Interests. The Middle-Tier REMIC shall hold as assets the uncertificated Lower-Tier Interests, other than the Class LT-R Interest. Each such Lower-Tier Interest is hereby designated as a REMIC regular interest. The Upper-Tier REMIC shall hold as assets the uncertificated Middle-Tier Interests, other than the Class MT-R Interest. Each such Middle-Tier Interest is hereby designated as a REMIC regular interest.

the principal balance of the LT-Group 3 Interest equals the excess of (I) the Pool Collateral Balance for Loan Group 3 as of for the immediately succeeding Distribution Date, over (II) the principal balance of the LT-Group 3 SCA Interest for such Distribution Date, after taking into account distributions pursuant to priority (i) above for such Distribution Date;

(iii)

(iv)

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

On any Distribution Date, after all distributions of Available Funds, Realized Losses shall be allocated among the Lower-Tier Interests in the same order of priority in which principal is distributed among such Lower-Tier Interests pursuant to priorities (i) and (ii) above.

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 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 on behalf of the Certificateholders.

(b)

Upon discovery or receipt of written notice 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 2.08 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 on behalf of the Trustee) shall promptly notify the Seller of such breach and request that the Seller cure such breach within 90 days from the date that the Seller was notified of such breach, and if the Seller does not cure such 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 Servicing 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 Originator’s or Seller’s obligation to repurchase such Mortgage Loan arises. Upon receipt of the related deposit in the Distribution Account, the Trustee shall cause the Custodian to release to the Originator or Seller, as applicable, the related Mortgage File and shall execute and deliver such instruments of transfer or assignment, in each case without recourse, representation or warranty, as the Originator or Seller, as applicable, shall furnish to it and as shall be necessary to vest in the Originator or Seller, 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 Custodian shall have no responsibility for determining the sufficiency of such assignment for its intended purpose).

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 the 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 a breach of a representation, warranty or covenant as described in this Section 2.03(d) and its obligation to indemnify the Trust Fund with respect to any such breach.

(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 Servicer to take), at the expense of the Seller (with the cooperation of the Depositor and the Trustee), 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. As 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 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. 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 Trustee 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, 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 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 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 applicable 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 Mortgage Loans:

It is understood and agreed that the representations and warranties 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.

It is understood and agreed that the obligations of the Seller set forth in Section 2.03(b) 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 or anti-abusive lending laws, indemnify for) a related Mortgage Loan pursuant to the Mortgage Loan Purchase Agreement constitute the sole remedies available to the Certificateholders or to the Trustee on their behalf respecting a breach of the representations and warranties incorporated in this Section 2.04.

ARTICLE III

ADMINISTRATION OF THE MORTGAGE LOANS

SECTION 3.01. Servicing of the Mortgage Loans.

The Servicer will service the Mortgage Loans pursuant to the terms of the Servicing Agreement. The Trustee shall enforce the provisions of the Servicing Agreement in respect of the Servicer (including any reference to any obligation of the Servicer in this Agreement that is incorporated into or by which the Servicer is bound under the Servicing Agreement).

SECTION 3.02. REMIC-Related Covenants.

For as long as any REMIC created hereunder shall exist, the Trustee shall act in accordance herewith to assure continuing treatment of such REMIC as a REMIC, and the Trustee shall comply with any directions of the Depositor or the Servicer to assure such continuing treatment. In particular, the Trustee shall not (a) sell or permit the sale of all or any portion of the Mortgage Loans or of any investment of deposits in an Account unless such sale is as a result of a repurchase of the Mortgage Loans pursuant to this Agreement or the Servicing Agreement or the Trustee has received a REMIC Opinion prepared at the expense of the Trust; and (b) other than with respect to a substitution pursuant to the Mortgage Loan Purchase Agreement or Section 2.03 or 2.04 of this Agreement or as otherwise provided in this Agreement or the Servicing Agreement, as applicable, accept any contribution to any REMIC after the Startup Day without receipt of a REMIC Opinion.

SECTION 3.03. Release of Mortgage Files.

(a)

Upon becoming aware of the payment in full of any Mortgage Loan, or the receipt by the Servicer of a notification that payment in full has been escrowed in a manner customary for such purposes for payment to Certificateholders on the next Distribution Date, the Servicer will, if required under the Servicing Agreement, promptly furnish to the Custodian, on behalf of the Trustee, two copies of a certification substantially in the form of Exhibit F hereto signed by a Servicing Officer or in a mutually agreeable electronic format which will, in lieu of a signature on its face, originate from a Servicing Officer (which certification shall include a statement to the effect that all amounts received in connection with such payment that are required to be deposited in the Servicing Account maintained by the Servicer the Servicing Agreement have been or will be so deposited) and shall request that the Trustee or the Custodian on behalf of the Trustee deliver to the Servicer the related Mortgage File. Upon receipt of such certification and request, the Trustee shall cause the Custodian to promptly release the related Mortgage File to the Servicer and the Trustee and the Custodian shall have no further responsibility with regard to such Mortgage File. Upon any such payment in full, the Servicer is authorized, to give, as agent for the Trustee, as the mortgagee under the Mortgage that secured the Mortgage Loan, an instrument of satisfaction (or assignment of mortgage without recourse) regarding the Mortgaged Property subject to the Mortgage, which instrument of satisfaction or assignment, as the case may be, shall be delivered to the Person or Persons entitled thereto against receipt therefor of such payment, it being understood and agreed that no expenses incurred in connection with such instrument of satisfaction or assignment, as the case may be, shall be chargeable to the Servicing Account.

(b)

From time to time and as appropriate for the servicing or foreclosure of any Mortgage Loan and in accordance with the Servicing Agreement, the Trustee shall execute such documents as shall be prepared and furnished to the Trustee by the Servicer (in form reasonably acceptable to the Trustee) and as are necessary to the prosecution of any such proceedings. The Trustee shall cause the Custodian, upon the request of the Servicer, and upon delivery to the Trustee (or the Custodian, on behalf of the Trustee) of two copies of a request for release signed by a Servicing Officer substantially in the form of Exhibit F (or in a mutually agreeable electronic format which will, in lieu of a signature on its face, originate from a Servicing Officer), release the related Mortgage File held in its possession or control to the Servicer. Such trust receipt shall obligate the Servicer to return the Mortgage File to the Custodian when the need therefor by the Servicer no longer exists unless the Mortgage Loan shall be liquidated, in which case, upon receipt of a certificate of a Servicing Officer similar to that hereinabove specified, the Mortgage File shall be released by the Custodian, to the Servicer.

SECTION 3.04. [Reserved].

Such amount shall be allocated among the other Loan Groups, pro rata based on aggregate Class Principal Balance of the related Senior Certificates, and paid to the Senior Certificates in such Group or Groups in the same priority as such Certificates would receive other distributions of principal pursuant to Section 5.01(a).

(ii)

On any Distribution Date on which the Senior Certificates and Principal-Only Component related to a Loan Group constitute an Undercollateralized Group, all amounts otherwise distributable as Available Funds on the Subordinate Certificates, in reverse order of priority (or, following the Senior Credit Support Depletion Date, such other amounts described in the immediately following sentence), will be distributed as principal to the Senior Certificates and Principal-Only Component of such Undercollateralized Group pursuant to Section 5.01(a), first, up to the sum of the Accrued Interest Amount and the Principal Deficiency Amount for the related Undercollateralized Group (such distribution, an “Undercollateralization Distribution”) and second, to pay to the Subordinate Certificates and the Class A-R Certificate in the same order and priority as provided in Section 5.01(a)(vi).

Each Depository Participant shall be responsible for disbursing such distribution to the Certificate Owners that it represents and to each indirect participating brokerage firm (a “brokerage firm” or “indirect participating firm”) for which it acts as agent. Each brokerage firm shall be responsible for disbursing funds to the Certificate Owners that it represents. All such credits and disbursements with respect to a Book-Entry Certificate are to be made by the Depository and the Depository Participants in accordance with the provisions of the Certificates. None of the Trustee, the Depositor or the Seller shall have any responsibility therefor.

SECTION 5.02. Allocation of Net Deferred Interest.

On each Distribution Date, any amount of Net Deferred Interest allocable to a Class of Certificates (other than the Interest-Only Certificates) on such Distribution Date will be added as principal to the outstanding Class Principal Balance of such Class of Certificates.

SECTION 5.03. Allocation of Realized Losses.

SECTION 5.07. Basis Risk Reserve Fund.

(a)

On the Closing Date, the Trustee shall establish and maintain in its name, in trust for the benefit of the holders of the LIBOR Certificates, a Basis Risk Reserve Fund, into which the Depositor shall deposit $740,000, which amount is intended to cover the amount of Basis Risk Shortfalls, if any, on the first, second and third Distribution Dates. On the third Distribution Date after the Closing Date, any interest accrued on such initial deposit and any amounts remaining from such initial deposit will be distributed to the Seller.

The Basis Risk Reserve Fund will be comprised of three subaccounts: the “Basis Risk Reserve Fund X-1 Subaccount,” the “Basis Risk Reserve Fund X-3A Subaccount” and the “Basis Risk Reserve Fund X-B Subaccount” (each, a “Subaccount”). The Basis Risk Reserve Fund X-1 Subaccount will be held in trust by the Trustee on behalf of the holders of the Class 1-A1A, Class 1-A1B, Class 1-A2A, Class 1-A2B, Class 2-A1A, Class 2-A1B and Class 2-A1C Certificates.

The Basis Risk Reserve Fund X-B Subaccount will be held in trust by the Trustee on behalf of the holders of the Subordinate Certificates. The Basis Risk Reserve Fund shall be an Eligible Account, and funds on deposit therein shall be held separate and apart from, and shall not be commingled with, any other moneys, including, without limitation, other moneys of the Trustee held pursuant to this Agreement. The Basis Risk Reserve Fund shall not be an asset of any REMIC established hereby.

(b)

On each Distribution Date, (i) Monthly Interest Distributable Amounts that would otherwise be distributable with respect to the Class X-1 Certificates shall instead be deposited in the Basis Risk Reserve Fund X-1 Subaccount to the extent of the X-1 Required Reserve Fund Deposit, (ii) Monthly Interest Distributable Amounts that would otherwise be distributable with respect to the Class X-3A Certificates shall instead be deposited in the Basis Risk Reserve Fund X-3A Subaccount to the extent of the X-3 Required Reserve Fund Deposit and (iii) Monthly Interest Distributable Amounts that would otherwise be distributable with respect to the Class X-B Certificates shall instead be deposited in the Basis Risk Reserve Fund X-B Subaccount to the extent of the X-B Required Reserve Fund Deposit.

(c)

On any Distribution Date for which a Basis Risk Shortfall exists with respect to the Class 1-A1A, Class 1-A1B, Class 1-A2A, Class 1-A2B, Class 2-A1A, Class 2-A1B, Class 2-A1C, Class 3-A1A, Class 3-A1B, Class 3-A1C and Subordinate Certificates, the Trustee, shall withdraw from the related Subaccount of the Basis Risk Reserve Fund the amount of any remaining Basis Risk Shortfall for such Classes of Certificates and distribute the amount withdrawn pursuant to Section 5.01(a)(v). If on any Distribution Date the amount on deposit in the Basis Risk Reserve Fund is not sufficient to make a full distribution of the Basis Risk Shortfall, the Trustee shall distribute such amount to such Classes of Certificates on a pro rata basis based on the amount of Basis Risk Shortfall due each such Class.

On any Distribution Date for which a Basis Risk Shortfall exists with respect to the Class B-1, Class B-2, Class B-3, Class B-4, Class B-5, Class B-6, Class B-7, Class B-8, Class B-9, Class B-10, Class B-11 and Class B-12 Certificates, the Trustee shall distribute pursuant to Section 5.01(a)(vii) the lesser of any amounts remaining on deposit in the Basis Risk Reserve Fund X-B Subaccount and such Basis Risk Shortfall to the Class B-1, Class B-2, Class B-3, Class B-4, Class B-5, Class B-6, Class B-7, Class B-8, Class B-9, Class B-10, Class B-11 and Class B-12 Certificates, sequentially, in that order.

Funds remaining in the applicable Subaccount of the Basis Risk Reserve Fund on any Distribution Date after funding the payment of Basis Risk Shortfalls for such Distribution Date will be remitted to the Interest-Only Certificates, up to the amount of the X-1 Required Reserve Fund Deposit, X-3A Required Reserve Fund Deposit or X-B Required Reserve Fund Deposit, as applicable.

(d)

Funds in the Basis Risk Reserve Fund shall be invested in Permitted Investments. The Holders of the Class X-1 Certificates shall direct the Trustee in writing as to the investment of amounts in the Basis Risk Reserve Fund X-1 Subaccount; the Holders of the X-3A Certificates shall direct the Trustee in writing as to the investment of amounts in the Basis Risk Reserve Fund X-3A Subaccount; and the Holders of the X-B Certificates shall direct the Trustee in writing as to the investment of amounts in the Basis Risk Reserve Fund X-B Subaccount. Any earnings on amounts in the various Subaccounts of the Basis Risk Reserve Fund shall be for the benefit of the Interest-Only Certificates related to the particular subaccount. The Interest-Only Certificates shall evidence ownership of the Basis Risk Reserve Fund for federal income tax purposes and the Holders thereof shall direct the Trustee, in writing, as to investment of amounts on deposit therein. The Class X-1, Class X-3A and Class X-B Certificateholder(s) shall be liable for any losses incurred on such investments. In the absence of written instructions from the Class X-1, Class X-3A and Class X-B Certificateholder(s) as to investment of funds on deposit in the Basis Risk Reserve Fund, such funds shall be invested in money market funds as specified by the Depositor and as described in clause (vi) of the definition of Permitted Investments in Article I. For all federal income tax purposes, amounts transferred by the Upper-Tier REMIC to the Basis Risk Reserve Fund shall be treated as amounts distributed by the Upper-Tier REMIC to the Class X-1, Class X-3A and Class X-B Certificateholders. Moreover, for federal income tax purposes, the Holders of the Class X-1 Certificates shall be considered to be the owners of the Basis Risk Reserve Fund X-1 Subaccount; the Holders of the Class X-3A Certificates shall be considered to be the owners of the Basis Risk Reserve Fund X-3A Subaccount; and the Holders of the Class X-B Certificates shall be considered to be the owners of the Basis Risk Reserve Fund X-B Subaccount.

(e)

Except as expressly provided hereunder, the Trustee shall have no obligation to invest cash held in the Basis Risk Reserve Fund in the absence of timely and specific written investment direction from the Depositor. In no event shall the Trustee be liable for the selection of investments or for investment losses incurred thereon. The Trustee shall have no liability in respect of losses incurred as a result of the liquidation of any investment prior to its stated maturity or the failure of the Depositor to provide timely written investment direction.

(f)

The Trustee or its Affiliates are permitted to receive additional compensation that could be deemed to be in the Trustee’s economic self interest for (i) serving as investment advisor, administrator, shareholder servicing agent, custodian or sub-custodian with respect to certain Permitted Investments, (ii) using Affiliates to effect transactions in certain Permitted Investments and (iii) effecting transactions in certain Permitted Investments. The Trustee does not guarantee the performance of any Permitted Investment.

(g) Upon termination of the Trust Fund any amounts remaining in the Basis Risk Reserve Fund shall be distributed to the Class X-1 Certificateholders.

SECTION 5.08. Recoveries.

(a)

With respect to any Class of Certificates or Principal-Only Component to which a Realized Loss has been allocated (including any such Class or Principal-Only Component for which the related Class Principal Balance or Component Principal Balance has been reduced to zero), the Class Principal Balance or Component Principal Balance of such Class or Component, as applicable, will be increased, up to the amount of related Recoveries for such Distribution Date as follows:

(i)

first, the Class Principal Balance of each Class of Senior Certificates or Component Principal Balance of the Principal-Only Component related to the Loan Group from which the Recovery was collected, will be increased pro rata, based on Realized Losses borne by such Class or Component up to the lesser of (i) (x) the excess amount by which Net Realized Losses previously borne by such Class or Component over (y) the amount of payments received under the Certificate Insurance Policy (that remain unreimbursed) with respect to such Realized Losses and (ii) Recoveries for such Distribution Date, and

(ii)

second, the Class Principal Balance of each Class of Subordinate Certificates will be increased in order of seniority, up to the amount by which Net Realized Losses previously allocated to each such Class exceeds the amount of Recoveries for such Distribution Date previously distributed to such Class.

(b)

Any increase to the Class Principal Balance of a Class of Certificates or Component Principal Balance of a Principal-Only Component shall increase the Certificate Principal Balance of each Certificate of the related Class or the Component Principal Balance of each PO Component pro rata in accordance with each Percentage Interest.

To the extent that the Certificate Insurer has made a payment in respect of Realized Losses and such amount has not previously been reimbursed pursuant to Section 5.01(a)(iv), the Certificate Insurer will be subrogated to the rights of the Holders of the Insured Certificates and will be entitled to the amount of any such Realized Losses paid by it to the Insured Certificates that remains unreimbursed prior to any Recoveries being allocated to the Holders of the Insured Certificates.

ARTICLE VI

Each Certificate shall, on original issue, be authenticated by the Certificate Registrar upon the order of the Depositor. No Certificate shall be entitled to any benefit under this Agreement or be valid for any purpose, unless such Certificate shall have been manually authenticated by the Certificate Registrar substantially in the form provided for herein, and such authentication upon any Certificate shall be conclusive evidence, and the only evidence, that such Certificate has been duly authenticated and delivered hereunder. All Certificates shall be dated the date of their authentication. At any time and from time to time after the execution and delivery of this Agreement, the Depositor may deliver Certificates executed by the Trustee to the Certificate Registrar for authentication and the Certificate Registrar shall authenticate and deliver such Certificates as provided in this Agreement and not otherwise.

The aggregate principal amounts of the Restricted Global Securities or Regulation S Global Securities, as applicable, may from time to time be increased or decreased by adjustments made on the records of the Certificate Registrar and DTC or its nominee, as the case may be, as hereinafter provided.

SECTION 6.02. Registration of Transfer and Exchange of Certificates.

(a)

The Certificate Registrar shall cause to be kept a Certificate Register in which, subject to such reasonable regulations as it may prescribe, the Certificate Registrar shall provide for the registration of Certificates and of transfers and exchanges of Certificates as herein provided. The Trustee is hereby appointed, and the Trustee hereby accepts its appointment as, initial Certificate Registrar, for the purpose of registering Certificates and transfers and exchanges of Certificates as herein provided.

Upon surrender for registration of transfer of any Certificate at the Corporate Trust Office of the Certificate Registrar maintained for such purpose pursuant to the foregoing paragraph, the Trustee on behalf of the Trust shall execute, and the Certificate Registrar shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates of the same aggregate Percentage Interest.

At the option of the Certificateholders, Certificates may be exchanged for other Certificates in authorized denominations and the same aggregate Percentage Interests, upon surrender of the Certificates to be exchanged at any such office or agency. Whenever any Certificates are so surrendered for exchange, the Trustee shall execute on behalf of the Trust, and the Certificate Registrar shall authenticate and deliver the Certificates which the Certificateholder making the exchange is entitled to receive. Every Certificate presented or surrendered for registration of transfer or exchange shall (if so required by the Certificate Registrar) be duly endorsed by, or be accompanied by a written instrument of transfer satisfactory to the Certificate Registrar duly executed by, the Holder thereof or his attorney duly authorized in writing.

(b)

Except as provided in paragraph (c) or (d) below, the Book-Entry Certificates shall at all times remain registered in the name of the Depository or its nominee and at all times: (i) registration of such Certificates may not be transferred by the Trustee or the Certificate Registrar except to another Depository; (ii) the Depository shall maintain book-entry records with respect to the Certificate Owners and with respect to ownership and transfers of such Certificates; (iii) ownership and transfers of registration of such Certificates on the books of the Depository shall be governed by applicable rules established by the Depository; (iv) the Depository may collect its usual and customary fees, charges and expenses from its Depository Participants; (v) the Certificate Registrar and the Trustee shall for all purposes deal with the Depository as representative of the Certificate Owners of the Certificates for purposes of exercising the rights of Holders under this Agreement, and requests and directions for and votes of such representative shall not be deemed to be inconsistent if they are made with respect to different Certificate Owners; (vi) the Trustee and the Certificate Registrar may rely and shall be fully protected in relying upon information furnished by the Depository with respect to its Depository Participants and furnished by the Depository Participants with respect to indirect participating firms and Persons shown on the books of such indirect participating firms as direct or indirect Certificate Owners; and (vii) the direct participants of the Depository shall have no rights under this Agreement under or with respect to any of the Certificates held on their behalf by the Depository, and the Depository may be treated by the Trustee, the Certificate Registrar and their respective agents, employees, officers and directors as the absolute owner of the Certificates for all purposes whatsoever.

All transfers by Certificate Owners of Book-Entry Certificates shall be made in accordance with the procedures established by the Depository Participant or brokerage firm representing such Certificate Owners. Each Depository Participant shall only transfer Book-Entry Certificates of Certificate Owners that it represents or of brokerage firms for which it acts as agent in accordance with the Depository’s normal procedures. The parties hereto are hereby authorized to execute one or more Letter of Representations with the Depository or take such other action as may be necessary or desirable to register a Book-Entry Certificate to the Depository. In the event of any conflict between the terms of any such Letter of Representation and this Agreement, the terms of this Agreement shall control.

(c)

If (x) the Depository or the Depositor advises the Certificate Registrar in writing that the Depository is no longer willing or able to discharge properly its responsibilities as Depository and (y) the Certificate Registrar or the Depositor is unable to locate a qualified successor, upon surrender to the Certificate Registrar of the Book-Entry Certificates by the Depository, accompanied by registration instructions from the Depository for registration, the Trustee shall at the Seller’s expense execute on behalf of the Trust and authenticate definitive, fully registered certificates (the “Definitive Certificates”). Neither the Depositor nor the Certificate Registrar shall be liable for any delay in delivery of such instructions and may conclusively rely on, and shall be protected in relying on, such instructions. Upon the issuance of Definitive Certificates, the Trustee, the Certificate Registrar and the Depositor shall recognize the Holders of the Definitive Certificates as Certificateholders hereunder.

(d)

No transfer, sale, pledge or other disposition of any Private Certificate, other than a Private Certificate sold in an offshore transaction in reliance on Regulation S, shall be made unless such disposition is exempt from the registration requirements of the Securities Act, and any applicable state securities laws or is made in accordance with the Securities Act and laws. Any Private Certificates sold to an “accredited investor” under Rule 501(a)(1), (2), (3) or (7) under the Securities Act shall be issued only in the form of one or more Definitive Certificates and the records of the Certificate Registrar and DTC or its nominee shall be adjusted to reflect the transfer of such Definitive Certificates. In the event of any transfer of any Private Certificate in the form of a Definitive Certificate, (i) the transferee shall certify (A) such transfer is made to a Qualified Institutional Buyer in reliance upon Rule 144A (as evidenced by an investment letter delivered to the Certificate Registrar, in substantially the form attached hereto as Exhibit J-2) under the Securities Act, or (B) such transfer is made to an “accredited investor” under Rule 501(c)(1), (2), (3) or (7) under the Securities Act (as evidenced by an investment letter delivered to the Certificate Registrar, in substantially the form attached hereto as Exhibit J-1, and, if so required by the Certificate Registrar and the Depositor, a written Opinion of Counsel (which may be in-house counsel) acceptable to and in form and substance reasonably satisfactory to the Certificate Registrar and the Depositor, delivered to the Certificate Registrar and the Depositor stating that such transfer may be made pursuant to an exemption, including a description of the applicable exemption and the basis therefor, from the Securities Act or is being made pursuant to the Securities Act, which Opinion of Counsel shall not be an expense of the Trust, the Trustee, the Certificate Registrar or the Depositor) or (ii) the Certificate Registrar shall require the transferor to execute a transferor certificate and the transferee to execute an investment letter acceptable to and in form and substance reasonably satisfactory to the Depositor and the Certificate Registrar certifying to the Depositor and the Certificate Registrar the facts surrounding such transfer, which investment letter shall not be an expense of the Trust, the Trustee, the Certificate Registrar or the Depositor. Each Holder of a Private Certificate desiring to effect such transfer shall, and does hereby agree to, indemnify the Trustee, the Certificate Registrar, the Seller and the Depositor against any liability that may result if the transfer is not so exempt or is not made in accordance with such federal and state laws.

In the case of a Private Certificate that is a Book-Entry Certificate, for purposes of the preceding paragraph, the representations set forth in the investment letter in clause (i) shall be deemed to have been made to the Certificate Registrar by the transferee’s acceptance of such Private Certificate that is also a Book-Entry Certificate (or the acceptance by a Certificate Owner of the beneficial interest in such Certificate).

If any Certificate Owner that is required under this Section 6.02(d) to transfer its Class B-10, Class B-11 or Class B-12 Certificates that are Book-Entry Certificates in the form of Definitive Certificates, (i) notifies the Trustee of such transfer or exchange and (ii) transfers such Book-Entry Certificates to the Trustee, in its capacity as such, through the book-entry facilities of the Depository, then the Trustee, on behalf of the Trust, shall decrease the balance of such Book-Entry Certificates, or the Trustee shall use reasonable efforts to cause the surrender to the Certificate Registrar of such Book-Entry Certificates by the Depository, and thereupon, the Trustee shall execute, authenticate and deliver to such Certificate Owner or its designee one or more Definitive Certificates in authorized denominations and with a like aggregate Certificate Principal Balance.

Subject to the provisions of this Section 6.02(d) governing registration of transfer and exchange Class B-10, Class B-11 or Class B-12 Certificates (i) held as Definitive Certificates may be transferred in the form of Book-Entry Certificates in reliance on Rule 144A (to one or more Qualified Institutional Buyers) or Regulation S under the Securities Act that are acquiring such Definitive Certificates, their own accounts for or for the accounts of other Qualified Institutional Buyers and (ii) held as Definitive Certificates by a Qualified Institutional Buyer or an investor under Regulation S for its own account or for the account of another Qualified Institutional Buyer or Regulation S investor may be exchanged for Book-Entry Certificates, in each case upon surrender of such Certificates for registration of transfer or exchange at the offices of the Trustee maintained for such purpose. Whenever any such Certificates are so surrendered for transfer or exchange, either the Trustee shall increase the balance of the related Book-Entry Certificates or the Trustee shall execute, authenticate and deliver the Book-Entry Certificates for which such Certificates were transferred or exchanged, as necessary and appropriate. No Holder of any such Definitive Certificates other than a Qualified Institutional Buyer or a Regulation S investor holding such Certificates for its own account or for the account of another Qualified Institutional Buyer or Regulation S investor may exchange such Certificates for Book-Entry Certificates. Further, any Certificate Owner of such Book-Entry Certificates other than any such Qualified Institutional Buyers or Regulation S investors shall notify the Trustee of its status as such and shall transfer such Book-Entry Certificate to the Trustee, through the book-entry facilities of the Depository, whereupon, and also upon surrender to the Trustee of such Book-Entry Certificates by the Depository, (which surrender the Trustee shall use reasonable efforts to cause to occur), the Trustee shall execute, authenticate and deliver to such Certificate Owner or such Certificate Owner’s nominee one or more Definitive Certificates in authorized denominations and with a like aggregate Certificate Principal Balance.

None of the Depositor, the Seller, the Certificate Registrar or the Trustee is obligated to register or qualify the Private Certificates under the Securities Act or any other securities laws or to take any action not otherwise required under this Agreement to permit the transfer of such Certificates without registration or qualification. Any Certificateholder desiring to effect the transfer of a Private Certificate shall, and does hereby agree to, indemnify the Trustee, the Seller, the Depositor and the Certificate Registrar against any liability that may result if the transfer is not so exempt or is not made in accordance with such federal and state laws.

No transfer of an ERISA-Restricted Certificate in the form of a Definitive Certificate shall be made unless the Certificate Registrar shall have received either (i) a representation from the transferee of such Certificate, acceptable to and in form and substance satisfactory to the Certificate Registrar and the Depositor (such requirement is satisfied only by the Certificate Registrar’s receipt of a representation letter from the transferee substantially in the form of Exhibit I-1 or I-2, as applicable, hereto), to the effect that such transferee is not an employee benefit plan subject to Section 406 of ERISA or a plan or arrangement subject to Section 4975 of the Code, nor a person acting on behalf of any such plan or arrangement nor using the assets of any such plan or arrangement to effect such transfer or (ii) if such Certificate has been the subject of an ERISA-Qualifying Underwriting, and the purchaser is an insurance company, a representation that the purchaser is an insurance company which is purchasing such Certificates with funds contained in an “insurance company general account” (as such term is defined in Section V(e) of Prohibited Transaction Class Exemption 95-60 (“PTCE 95-60”) and that the purchase and holding of such Certificates are covered under Sections I and III of PTCE 95-60 or (iii) an Opinion of Counsel satisfactory to the Certificate Registrar, which Opinion of Counsel shall not be an expense of the Trustee, the Certificate Registrar, the Servicer, the Depositor or the Trust, addressed to the Certificate Registrar, to the effect that the purchase and holding of such ERISA-Restricted Certificate in the form of a Definitive Certificate will not result in a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code and will not subject the Trustee, the Certificate Registrar, the Servicer, or the Depositor to any obligation in addition to those expressly undertaken in this Agreement or to any liability. Notwithstanding anything else to the contrary herein, any purported transfer of an ERISA-Restricted Certificate in the form of a Definitive Certificate to an employee benefit plan subject to ERISA or Section 4975 of the Code without the delivery to the Certificate Registrar of an Opinion of Counsel satisfactory to the Certificate Registrar as described above shall be void and of no effect.

In the case of an ERISA-Restricted Certificate that is a Book-Entry Certificate, for purposes of clauses (i) or (ii) of the first sentence of the preceding paragraph, such representations shall be deemed to have been made to the Certificate Registrar by the transferee’s acceptance of such ERISA-Restricted Certificate that is also a Book-Entry Certificate (or the acceptance by a Certificate Owner of the beneficial interest in such Certificate).

To the extent permitted under applicable law (including, but not limited to, ERISA), none of the Trustee, the Certificate Registrar or the Depositor shall have any liability to any Person for any registration of transfer of any ERISA-Restricted Certificate that is in fact not permitted by this Section 6.02(d) so long as the transfer was registered by the Certificate Registrar in accordance with the foregoing requirements. In addition, none of the Trustee, the Certificate Registrar or the Depositor shall be required to monitor, determine or inquire as to compliance with the transfer restrictions with respect to any ERISA-Restricted Certificate in the form of a Book-Entry Certificate, and none of the Trustee, the Certificate Registrar or the Depositor shall have any liability for transfers of Book-Entry Certificates or any interests therein made in violation of the restrictions on transfer described in the Prospectus Supplement and this Agreement.

Each Person who has or who acquires any Ownership Interest in a Residual Certificate shall be deemed by the acceptance or acquisition of such Ownership Interest to have agreed to be bound by the following provisions and to have irrevocably appointed the Depositor or its designee as its attorney-in-fact to negotiate the terms of any mandatory sale under clause (v) below and to execute all instruments of transfer and to do all other things necessary in connection with any such sale, and the rights of each Person acquiring any Ownership Interest in a Residual Certificate are expressly subject to the following provisions:

(i)

Each Person holding or acquiring any Ownership Interest in a Residual Certificate shall be a Permitted Transferee who acquires such Ownership Interest in a Residual Certificate for its own account and not in the capacity as trustee, nominee or agent for another Person and shall promptly notify the Certificate Registrar and the Trustee of any change or impending change in its status as such a Permitted Transferee.

(ii)

No Ownership Interest in a Residual Certificate may be registered on the Closing Date and no Ownership Interest in a Residual Certificate may thereafter be transferred, and the Certificate Registrar shall not register the Transfer of a Residual Certificate unless, in addition to the certificates required to be delivered under subsection (d) above, the Trustee and the Certificate Registrar shall have been furnished with an affidavit (“Transfer Affidavit”) of the initial owner of such Residual Certificate or proposed transferee of a Residual Certificate in the form attached hereto as Exhibit L.

(iii)

In connection with any proposed transfer of any Ownership Interest in a Residual Certificate, the Trustee and the Certificate Registrar shall as a condition to registration of the transfer, require delivery to them of a Transferor Certificate in the form of Exhibit K hereto from the proposed transferor to the effect that the transferor (a) has no knowledge the proposed Transferee is not a Permitted Transferee acquiring an Ownership Interest in such Residual Certificate for its own account and not in a capacity as trustee, nominee, or agent for another Person, and (b) has not undertaken the proposed transfer in whole or in part to impede the assessment or collection of tax.

(iv)

Any attempted or purported Transfer of any Ownership Interest in a Residual Certificate in violation of the provisions of this Section shall be absolutely null and void and shall vest no rights in the purported transferee. If any purported transferee shall, in violation of the provisions of this Section, become a Holder of such Residual Certificate, then the prior Holder of such Residual Certificate that is a Permitted Transferee shall, upon discovery that the registration of Transfer of such Residual Certificate was not in fact permitted by this Section, be restored to all rights as Holder thereof retroactive to the date of registration of transfer of such Residual Certificate. None of the Trustee, the Certificate Registrar or the Depositor shall have any liability to any Person for any registration of Transfer of a Residual Certificate that is in fact not permitted by this Section so long as the Trustee and the Certificate Registrar received the documents specified in clause (iii). The Certificate Registrar shall be entitled to recover from any Holder of such Residual Certificate that was in fact not a Permitted Transferee at the time such distributions were made all distributions made on such Residual Certificate. Any such distributions so recovered by the Certificate Registrar shall be distributed and delivered by the Certificate Registrar to the last Holder of such Residual Certificate that is a Permitted Transferee.

(v)

If any Person other than a Permitted Transferee acquires any Ownership Interest in a Residual Certificate in violation of the restrictions in this Section, then the Trustee shall have the right but not the obligation, without notice to the Holder of such Residual Certificate or any other Person having an Ownership Interest therein, to notify the Depositor to arrange for the sale of such Residual Certificate. The proceeds of such sale, net of commissions (which may include commissions payable to the Depositor or its affiliates in connection with such sale), expenses and taxes due, if any, will be remitted by the Certificate Registrar to the previous Holder of such Residual Certificate that is a Permitted Transferee, except that in the event that the Certificate Registrar determines that the Holder of such Residual Certificate may be liable for any amount due under this Section or any other provisions of this Agreement, the Certificate Registrar may withhold a corresponding amount from such remittance as security for such claim. The terms and conditions of any sale under this clause (v) shall be determined in the sole discretion of the Trustee and the Certificate Registrar and they shall not be liable to any Person having an Ownership Interest in such Residual Certificate as a result of its exercise of such discretion.

(vi)

If any Person other than a Permitted Transferee acquires any Ownership Interest in a Residual Certificate in violation of the restrictions in this Section, then the Trustee upon receipt of reasonable compensation will provide to the Internal Revenue Service, and to the persons specified in Sections 860E(e)(3) and (6) of the Code, information needed to compute the tax imposed under Section 860E(e)(5) of the Code on transfers of residual interests to disqualified organizations.

The foregoing provisions of this Section shall cease to apply to transfers occurring on or after the date on which there shall have been delivered to the Certificate Registrar and the Servicer, in form and substance satisfactory to the Certificate Registrar, (i) written notification from each Rating Agency that the removal of the restrictions on Transfer set forth in this Section will not cause such Rating Agency to downgrade its ratings of the Certificates (determined in the case of the Insured Certificates, without giving effect to the Certificate Insurance Policy) and (ii) an Opinion of Counsel to the effect that such removal will not cause the REMIC created hereunder to fail to qualify as a REMIC.

(f)

Notwithstanding any provision to the contrary herein, so long as a Restricted Global Security or Regulation S Global Security, as applicable, representing the Certificates remains outstanding and is held by or on behalf of the Depository, transfers of a Restricted Global Security or Regulation S Global Security, as applicable, representing the Certificates, in whole or in part, shall only be made in accordance with Section 6.01 and this Section 6.02(f).

(i)

Subject to clauses (ii) and (iii) of this Section 6.02(f), transfers of a Restricted Global Security or Regulation S Global Security, as applicable, representing the Certificates shall be limited to transfers of such a Restricted Global Security or Regulation S Global Security, as applicable, in whole, but not in part, to nominees of the Depository or to a successor of the Depository or such successor’s nominee.

(ii)

Restricted Global Security to Regulation S Global Security. If a holder of a beneficial interest in a Restricted Global Security deposited with or on behalf of the Depository wishes at any time to exchange its interest in such Restricted Global Security for an interest in a Regulation S Global Security, or to transfer its interest in such Restricted Global Security to a Person who wishes to take delivery thereof in the form of an interest in a Regulation S Global Security, such holder, provided such holder is not a U.S. Person, may, subject to the rules and procedures of the Depository, exchange or cause the exchange of such interest for an equivalent beneficial interest in the Regulation S Global Security.

(iii)

Regulation S Global Security to Restricted Global Security. If a holder of a beneficial interest in a Regulation S Global Security deposited with or on behalf of the Depository wishes at any time to transfer its interest in such Regulation S Global Security to a Person who wishes to take delivery thereof in the form of an interest in a Restricted Global Security, such holder may, subject to the rules and procedures of the Depository, exchange or cause the exchange of such interest for an equivalent beneficial interest in a Restricted Global Security. Upon receipt by the Trustee, as Certificate Registrar, of (A) instructions from the Depository directing the Trustee, as Certificate Registrar, to cause to be credited a beneficial interest in a Restricted Global Security in an amount equal to the beneficial interest in such Regulation S Global Security to be exchanged but not less than the minimum denomination applicable to such Certificateholder’s Certificates held through a Restricted Global Security, to be exchanged, such instructions to contain information regarding the participant account with the Depository to be credited with such increase, and (B) a certificate in the form of Exhibit N-2 hereto given by the holder of such beneficial interest and stating, among other things, that the Person transferring such interest in such Regulation S Global Security reasonably believes that the Person acquiring such interest in a Restricted Global Security is a qualified institutional buyer within the meaning of Rule 144A, is obtaining such beneficial interest in a transaction meeting the requirements of Rule 144A and in accordance with any applicable securities laws of any State of the United States or any other jurisdiction, then the Trustee, as Certificate Registrar, will reduce the principal amount of the Regulation S Global Security and increase the principal amount of the Restricted Global Security by the aggregate principal amount of the beneficial interest in the Regulation S Global Security to be transferred and the Trustee, as Certificate Registrar, shall instruct the Depository, concurrently with such reduction, to credit or cause to be credited to the account of the Person specified in such instructions a beneficial interest in the Restricted Global Security equal to the reduction in the principal amount of the Regulation S Global Security.

(iv)

Other Exchanges. In the event that a Restricted Global Security or Regulation S Global Security, as applicable, is exchanged for Certificates in definitive registered form without interest coupons, such Certificates may be exchanged for one another only in accordance with such procedures as are substantially consistent with the provisions above (including certification requirements intended to insure that such transfers comply with Rule 144A or are to non-U.S. Persons, or otherwise comply with Regulation S under the Securities Act, as the case may be, and as may be from time to time adopted by the Depositor and the Trustee.

(v)

Restrictions on U.S. Transfers. Transfers of interests in the Regulation S Global Security to U.S. persons (as defined in Regulation S) shall be limited to transfers made pursuant to the provisions of Section 6.02(f)(iii).

(g)

No service charge shall be made for any registration of transfer or exchange of Certificates of any Class, but the Certificate Registrar may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any transfer or exchange of Certificates.

All Certificates surrendered for registration of transfer or exchange shall be cancelled by the Certificate Registrar and disposed of pursuant to its standard procedures.

SECTION 6.03. Mutilated, Destroyed, Lost or Stolen Certificates.

If (i) any mutilated Certificate is surrendered to the Trustee or the Certificate Registrar or the Trustee or the Certificate Registrar receives evidence to its satisfaction of the destruction, loss or theft of any Certificate and (ii) there is delivered to the Trustee and the Depositor (and with respect to the Insured Certificates, the Certificate Insurer) such security or indemnity as may be required by them to save each of them harmless, then, in the absence of notice to the Trustee, the Depositor or the Certificate Registrar (and, with respect to the Insured Certificates, the Certificate Insurer) that such Certificate has been acquired by a bona fide purchaser, the Trustee shall execute on behalf of the Trust and the Certificate Registrar shall authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new Certificate of like tenor and Percentage Interest.

ARTICLE VII

DEFAULT

SECTION 7.01. Events of Default.

If an Event of Default described in a Servicing Agreement shall occur and be continuing, then, and in each and every such case, so long as an Event of Default shall not have been remedied within the applicable grace period, the Trustee may, and at the written direction of the Holders of Certificates evidencing Voting Rights aggregating not less than 51%, shall, by notice then given in writing to the Servicer, terminate all of the rights and obligations of the Servicer as servicer under this Agreement. Any such notice to the Servicer shall also be given to the Rating Agencies, the Depositor, the Certificate Insurer and the Seller. The Trustee, upon a Responsible Officer having actual knowledge of such default, shall deliver a written notice to the Servicer of the Event of Default on any Servicer Remittance Date on which the Servicer fails to make any deposit or payment required pursuant to the Servicing Agreement (including but not limited to Advances to the extent required pursuant to the Servicing Agreement). Pursuant to the Servicing Agreement, on or after the receipt by the Servicer (and by the Trustee if such notice is given by the Certificate Insurer or the Holders) of such written notice, all authority and power of the Servicer under the Servicing Agreement, with respect to the Mortgage Loans or otherwise, shall pass to and be vested in the Trustee and the Trustee is hereby authorized and empowered to execute and deliver, on behalf of the Servicer, as attorney-in-fact or otherwise, any and all documents and other instruments, and to do or accomplish all other acts or things necessary or appropriate to effect the purposes of such notice of termination, whether to complete the transfer and endorsement of each Mortgage Loan and related documents or otherwise.

SECTION 7.02. Trustee to Act.

(a)

From and after the date the Servicer (and the Trustee, if notice is sent by the Certificate Insurer or the Holders) receives a notice of termination pursuant to Section 7.01, the Trustee immediately shall be the successor in all respects to the Servicer in its capacity as servicer under the Servicing Agreement and the transactions set forth or provided for herein and shall be subject to all the responsibilities, duties and liabilities relating thereto placed on the Servicer by the terms and provisions hereof arising on and after its succession, including the immediate obligation to make Advances. As compensation therefor, the Trustee shall be entitled to such compensation as the Servicer would have been entitled to under the Servicing Agreement if no such notice of termination had been given. Notwithstanding the above, (i) if the Trustee is unwilling to act as successor Servicer or (ii) if the Trustee is legally unable so to act, the Trustee shall appoint or petition a court of competent jurisdiction to appoint, any established housing and home finance institution, bank or other mortgage loan or home equity loan servicer having a net worth of not less than $15,000,000 as the successor to the Servicer under the Servicing Agreement in the assumption of all or any part of the responsibilities, duties or liabilities of the Servicer under the Servicing Agreement; provided, that the appointment of any such successor Servicer shall not result in the qualification, reduction or withdrawal of the ratings assigned to the Certificates by each Rating Agency as evidenced by a letter to such effect from such Rating Agency. Pending appointment of a successor to the Servicer under the Servicing Agreement, unless the Trustee is prohibited by law from so acting, the Trustee shall act in such capacity as hereinabove provided. In connection with such appointment and assumption, the successor shall be entitled to receive compensation out of payments on Mortgage Loans in an amount equal to the compensation which the Servicer would otherwise have received hereunder. Except with respect to the making of Advances the defaulting Servicer was required to make but did not make, the successor Servicer, including the Trustee in such capacity, shall not be liable for any acts or omissions of the predecessor Servicer or for any breach by such Servicer of any of its representations or warranties made by it in the Servicing Agreement or in any related document or agreement. The Trustee and such successor shall take such action, consistent with this Agreement, as shall be necessary to effectuate any such succession.

(b)

Any successor, including the Trustee, to the Servicer under the Servicing Agreement shall during the term of its service as Servicer continue to service and administer the Mortgage Loans for the benefit of Certificateholders and the Certificate Insurer pursuant to the terms and conditions of the Servicing Agreement, and maintain in force a policy or policies of insurance covering errors and omissions in the performance of its obligations as Servicer under the Servicing Agreement.

(c)

Notwithstanding anything else herein to the contrary, in no event shall the Trustee be liable for any servicing fee or for any differential in the amount of the servicing fee paid hereunder and the amount necessary to induce any successor Servicer to act as successor Servicer under this Agreement and the transactions set forth or provided for herein.

(d)

The Trustee shall be entitled to be reimbursed by the Trust Fund (pursuant to Section 4.03(a)(xii)), in the event that the Servicer does not reimburse the Trustee under the Servicing Agreement, for all costs associated with the transfer of servicing from the predecessor Servicer, including, without limitation, any costs or expenses associated with the termination of the predecessor Servicer, the appointment of a successor servicer, the complete transfer of all servicing data and the completion, correction or manipulation of such servicing data as may be required by the Trustee or any successor servicer to correct any errors or insufficiencies in the servicing data or otherwise to enable the Trustee or successor servicer to service the Mortgage Loans property and effectively.

SECTION 7.03. Waiver of Event of Default.

The Majority Certificateholders may, on behalf of all Certificateholders, by notice in writing to the Trustee, direct the Trustee to waive any events permitting removal of the Servicer under this Agreement, provided, however, that the Majority Certificateholders may not waive an event that results in a failure to make any required distribution on a Certificate without the consent of the Holder of such Certificate. Upon any waiver of an Event of Default, such event shall cease to exist and any Event of Default arising therefrom shall be deemed to have been remedied for every purpose of this Agreement. No such waiver shall extend to any subsequent or other event or impair any right consequent thereto except to the extent expressly so waived. Notice of any such waiver shall be given by the Trustee to the Rating Agencies and the Certificate Insurer.

SECTION 7.04. Notification to Certificateholders.

(a)

Upon any termination or appointment of a successor to the Servicer pursuant to this Article VII, the Trustee shall give prompt written notice thereof to the Certificate Insurer, the Certificateholders and each Rating Agency.

(b)

No later than 60 days after the occurrence of any event which constitutes or which, with notice or a lapse of time or both, would constitute an Event of Default of which a Responsible Officer of the Trustee becomes aware of the occurrence of such an event, the Trustee shall transmit by mail to the Certificate Insurer and all Certificateholders notice of such occurrence unless such Event of Default shall have been waived or cured.

ARTICLE VIII

THE TRUSTEE

SECTION 8.01. Duties of the Trustee

(a)

The Trustee, prior to the occurrence of an Event of Default and after the curing or waiver of all Events of Default which may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Agreement. If an Event of Default has occurred (which has not been cured or waived) of which a Responsible Officer has actual knowledge, the Trustee shall exercise such of the rights and powers vested in it by this Agreement, and use the same degree of care and skill in their exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs.

The Trustee, upon receipt of all resolutions, certificates, statements, opinions, reports, documents, orders or other instruments furnished to the Trustee, which are specifically required to be furnished pursuant to any provision of this Agreement, shall examine them to determine whether they conform to the requirements of this Agreement; provided, however, that the Trustee will not be responsible for the accuracy or content of any such resolutions, certificates, statements, opinions, reports, documents or other instruments. If any such instrument is found not to conform to the requirements of this Agreement in a material manner, the Trustee shall take such action as it deems appropriate to have the instrument corrected.

On each Distribution Date, the Trustee, shall make monthly distributions and the final distribution to the Certificateholders from funds in the Distribution Account as provided in Sections 5.01 and 10.01 herein.

No provision of this Agreement shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act or its own willful misconduct; provided, however, that:

(i)

prior to the occurrence of an Event of Default, and after the curing of all such Events of Default which may have occurred, the duties and obligations of the Trustee shall be determined solely by the express provisions of this Agreement, the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Agreement, no implied covenants or obligations shall be read into this Agreement against the Trustee and, in the absence of bad faith on the part of the Trustee, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of this Agreement;

(ii)

the Trustee shall not be liable for an error of judgment made in good faith by a Responsible Officer of the Trustee unless it shall be proved that the Trustee was negligent in ascertaining or investigating the facts related thereto;

(iii)

the Trustee shall not be personally liable with respect to any action taken, suffered or omitted to be taken by it in good faith in accordance with the consent or at the direction of Holders of Certificates as provided herein relating to the time, method and place of conducting any remedy pursuant to this Agreement, or exercising or omitting to exercise any trust or power conferred upon the Trustee under this Agreement;

the Trustee shall not be responsible for any act or omission of the Servicer (except in its capacity as successor servicer to the extent provided in Section 7.02(a)), the Depositor, the Seller or the Custodian, or any successor Custodian; and

(v)

the Trustee shall not be charged with knowledge of any Event of Default unless a Responsible Officer of the Trustee at the Corporate Trust Office obtains actual knowledge of such failure or the Trustee receives written notice at the Corporate Trust Office of such Event of Default.

The Trustee shall not be required to expend or risk its own funds or otherwise incur financial or other liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if there is reasonable ground for believing that the repayment of such funds or indemnity satisfactory to it against such risk or liability is not assured to it, and none of the provisions contained in this Agreement shall in any event require the Trustee to perform, or be responsible for the manner of performance of, any of the obligations of the Servicer under the Servicing Agreement, except during such time, if any, as the Trustee shall be the successor to, and be vested with the rights, duties, powers and privileges of, the Servicer in accordance with the terms of the Servicing Agreement.

(b)

On or prior to the Closing Date, the Trustee shall deliver to the Sponsor and the Depositor a certification in the form of Exhibit R attached hereto specifying the items it will address in its assessment of compliance with the servicing criteria under this Section 8.01. On or before March 1 of each calendar year, beginning with March 1, 2007 (but in no event later than March 15th) unless and until a Form 15 Suspension Notice has been filed by the Trustee, the Trustee shall deliver to the Sponsor and the Depositor a report regarding its assessment of compliance with the servicing criteria that it has identified in its certification in the form of Exhibit R, as of and for the period ending the end of the fiscal year ending no later than December 31 of the year prior to the year of delivery of the report, with respect to asset-backed security transactions taken as a whole in which the Trustee is performing any activities that address any of the servicing criteria identified by it in such certification and that are backed by the same asset type backing such asset-backed securities. Each such report shall include (a) a statement of the party’s responsibility for assessing compliance with the servicing criteria applicable to such party, (b) a statement that such party used the criteria identified in Item 1122(d) of Regulation AB (§ 229.1122(d)) to assess compliance with the applicable servicing criteria, (c) disclosure of any material instance of noncompliance identified by such party and (d) a statement that a registered public accounting firm has issued an attestation report on such party’s assessment of compliance with the applicable servicing criteria, which report shall be delivered by the Trustee as provided in section 8.01(c).

(c)

On or before March 1st of each calendar year, beginning with March 1, 2007 (but in no event later than March 15th) unless and until a Form 15 Suspension Notice has been filed by the Trustee, the Trustee shall, at its own expense, cause a firm of independent public accountants (who may also render other services to Trustee), which is a member of the American Institute of Certified Public Accountants, to furnish to the Sponsor and the Depositor a report to the effect that such firm that attests to, and reports on, the assessment made by such asserting party pursuant to Section 8.01(b) above, which report shall be made in accordance with standards for attestation engagements issued or adopted by the Public Company Accounting Oversight Board.

On or before March 1 of each year, the Depositor shall distribute the information on Exhibit S to the Trustee.

(f)

Each of the parties hereto acknowledges and agrees that the purpose of this Section 8.01(b)-(e) is to facilitate compliance by the Seller and the Depositor with the provisions of Regulation AB, as such may be amended or clarified from time to time. Therefore, each of the parties agrees that the parties’ obligations hereunder will be supplemented and modified as necessary to be consistent with any such amendments, interpretive advice or guidance, convention or consensus among active participants in the asset-backed securities markets, advice of counsel, or otherwise in respect of the requirements of Regulation AB and the parties shall comply, to the extent practicable from a timing and information systems perspective, with requests made by the Seller or the Depositor for delivery of additional or different information as the Sponsor or the Depositor may determine in good faith is necessary to comply with the provisions of Regulation AB.

The Trustee’s obligation to provide assessments of compliance and attestations under this Section 8.01 shall terminate upon the filing of a Form 15 suspension notice on behalf of the Trust Fund. Notwithstanding the foregoing, after the occurrence of such event, and provided the Depositor is not otherwise provided with such reports or copies of such reports, the Trustee shall be obligated to provide a copy of such reports, by March 15 of each year, to the Depositor.

If such entity publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section 8.06, the combined capital and surplus of such entity shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. The principal office of the Trustee (other than the initial Trustee) shall be in a state with respect to which an Opinion of Counsel has been delivered to such Trustee at the time such Trustee is appointed Trustee to the effect that the Trust will not be a taxable entity under the laws of such state. In case at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section 8.06, the Trustee shall resign immediately in the manner and with the effect specified in Section 8.07 hereof.

SECTION 8.07. Resignation or Removal of Trustee

The Trustee (including the Trustee as Certificate Registrar) may at any time resign and be discharged from the trust hereby created by giving written notice thereof to the Trustee, the Depositor, the Seller, the Certificate Insurer and the Rating Agencies. Upon receiving such notice of resignation of the Trustee, the Depositor shall promptly appoint a successor Trustee that meets the requirements in Section 8.06 by written instrument, in duplicate, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor Trustee. If no successor Trustee shall have been so appointed and having accepted appointment within 30 days after the giving of such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor Trustee.

If at any time the Trustee (a) shall cease to be eligible in accordance with the provisions of Section 8.06 hereof, (b) shall be legally unable to act, or shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, (c) shall fail to deliver to the Depositor and the Sponsor the information, attestations or reports required pursuant to Section 8.01(b) through (d) hereto or (d) shall fail to file any Form 10-D, Form 8-K or Form 10-K when due pursuant to Section 3.05 hereof (other than that arising from the Trustee’s inability or failure to obtain or receive, on a timely basis, any information from any other party needed to prepare, arrange for execution or file such Form 10-D, Form 8-K or Form 10-K, as applicable, not resulting from its own negligence, bad faith or willful misconduct), then the Depositor may immediately remove the Trustee. If the Depositor removes the Trustee under the authority of the immediately preceding sentence, the Depositor shall promptly appoint a successor Trustee that meets the requirements of Section 8.06, by written instrument, in triplicate, one copy of which instrument shall be delivered to the Trustee so removed, and one copy to the successor Trustee and one copy to the Certificate Insurer.

The Majority Certificateholders may at any time remove the Trustee by written instrument or instruments delivered to the Depositor and the Trustee; the Depositor or the Trustee shall thereupon use its best efforts to appoint a successor Trustee in accordance with this Section.

Any resignation or removal of the Trustee and appointment of a successor Trustee pursuant to any of the provisions of this Section 8.07 shall not become effective until acceptance of appointment by the successor Trustee as provided in Section 8.08 hereof. As long as the Certificate Insurance Policy is in effect, the Trustee will send a written notice to the Certificate Insurer of any such resignation, removal or appointment.

SECTION 8.08. Successor Trustee

Any successor Trustee appointed as provided in Section 8.07 hereof shall execute, acknowledge and deliver to the Depositor and the Seller and to its predecessor Trustee (i) an instrument accepting such appointment hereunder and (ii) the certification required pursuant to the first sentence of Section 8.02(b) hereof, and thereupon the resignation or removal of the predecessor Trustee shall become effective, and such successor Trustee without any further act, deed or conveyance, shall become fully vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as Trustee. The Depositor, the Seller, and the predecessor Trustee shall execute and deliver such instruments and do such other things as may reasonably be required for fully and certainly vesting and confirming in the successor Trustee, as applicable, all such rights, powers, duties and obligations.

Upon acceptance of appointment by a successor Trustee as provided in this Section 8.08, the successor Trustee shall mail notice of such appointment hereunder to all Holders of Certificates at their addresses as shown in the Certificate Register, to the Certificate Insurer and to each Rating Agency.

SECTION 8.09. Merger or Consolidation of Trustee

Any entity into which the Trustee may be merged or converted or with which it may be consolidated, or any entity resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any entity succeeding to all or substantially all of the business of the Trustee shall be the successor of the Trustee hereunder, provided such entity shall be eligible under the provisions of Section 8.06 and 8.08 hereof, without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding.

SECTION 8.10. Appointment of Co-Trustee or Separate Trustee.

Notwithstanding any other provisions of this Agreement, at any time, for the purpose of meeting any legal requirements of any jurisdiction in which any part of the Trust or any Mortgaged Property may at the time be located, the Depositor and the Trustee acting jointly shall have the power, and the Trustee shall, and shall instruct the Depositor to, at the expense of the Trust Fund, execute and deliver all instruments to appoint one or more Persons approved by the Trustee to act as co-trustee or co-trustees, jointly with the Trustee, or separate trustee or separate trustees, of all or any part of the Trust, and to vest in such Person or Persons, in such capacity and for the benefit of the Certificateholders and the Certificate Insurer, such title to the Trust, or any part thereof, and, subject to the other provisions of this Section 8.10, such powers, duties, obligations, rights and trusts as the Depositor and the Trustee may consider necessary or desirable.

(ii)

no trustee hereunder shall be held personally liable by reason of any act or omission of any other trustee hereunder; and

Each separate trustee and co-trustee, upon its acceptance of the trusts conferred, shall be vested with the estates or property specified in its instrument of appointment, either jointly with the Trustee or separately, as may be provided therein, subject to all the provisions of this Agreement, specifically including every provision of this Agreement relating to the conduct of, affecting the liability of, or affording protection to, the Trustee. Every such instrument shall be filed with the Trustee and a copy thereof given to the Depositor.

Any separate trustee or co-trustee may, at any time, constitute the Trustee, its agent or attorney-in-fact, with full power and authority, to the extent not prohibited by law, to do any lawful act under or in respect of this Agreement on its behalf and in its name.

In addition, prior to taking any action with respect to any REMIC created hereunder or the assets therein, or causing any such REMIC to take any action which is not expressly permitted under the terms of this Agreement, any Holder of a Residual Certificate will consult with the Trustee, or its designee, in writing, with respect to whether such action could cause an Adverse REMIC Event to occur with respect to any such REMIC, and no such Person shall take any such action or cause any REMIC created hereunder to take any such action as to which the Trustee has advised it in writing that an Adverse REMIC Event could occur.

(g)

Each Holder of a Residual Certificate shall pay when due any and all taxes imposed on any REMIC created hereunder in which it owns the residual interest by federal or state governmental authorities.

TERMINATION

SECTION 10.01. Termination.

(a)

The respective obligations and responsibilities of the Seller, the Depositor, and the Trustee created hereby (other than the obligation of the Trustee to make certain payments to Certificateholders after the final Distribution Date and the obligation of the Servicer to send certain notices as hereinafter set forth) shall terminate upon the earliest of (i) the Distribution Date on which the Class Principal Balance of each Class of Certificates has been reduced to zero and no Certificate Insurer Reimbursement Amounts are owed to the Certificate Insurer, (ii) the final payment or other liquidation of the last Mortgage Loan, (iii) the optional purchase of the Mortgage Loans as described in the following paragraph and (iv) the Latest Possible Maturity Date.

Following the date on which the aggregate of the Stated Principal Balances of the Mortgage Loans (after giving effect to scheduled payments of principal due during the related Due Period, to the extent received or advanced, and unscheduled collections of principal received during the related Prepayment Period) on such date is equal to or less than 10% of the Cut-off Date Collateral Balance (the “Call Option Date”), the Servicer may, at its option, terminate this Agreement with regard to such Mortgage Loans by purchasing, on the next succeeding Distribution Date, all of the outstanding Mortgage Loans and related REO Properties at a price equal to (A) the greater of (i) the aggregate Stated Principal Balance of the Mortgage Loans, as applicable, (after giving effect to scheduled payments of principal due during the related Due Period, to the extent received or advanced, and unscheduled collections of principal received during the related Prepayment Period) and the appraised value of the REO Properties and (ii) the fair market value of the Mortgage Loans and REO Properties (as determined and as agreed upon by (x) the Servicer and (y) the Holders of a majority in Percentage Interest of the Class A-R-II Certificates in their good faith business judgment as of the close of business on the third Business Day next preceding the date upon which notice of any such termination is furnished to the Certificateholders pursuant to Section 10.01(b)), plus, (B) in each case, accrued and unpaid interest thereon at the weighted average of the Mortgage Rates of the Mortgage Loans through the end of the Due Period preceding the final Distribution Date, plus any unreimbursed Servicing Advances and Advances and any unpaid Servicing Fees allocable to such Mortgage Loans and REO Properties and all amounts, if any, then due and owing to the Trustee and the Certificate Insurer under this Agreement (the “Termination Price”); provided, however, such option may only be exercised if the Termination Price is sufficient to result in the payment of all interest accrued on, as well as amounts necessary to retire the Class Principal Balance of each Class of Certificates issued pursuant to this Agreement. The fair market value of the Mortgage Loans and REO Properties shall be required to be made and agreed upon by the Servicer and the Holders of a majority in Percentage Interest of the Class A-R-II Certificates as provided in (ii) above in their good faith business judgment, and such determination shall take into consideration an appraisal of the value of the Mortgage Loans and REO Properties conducted by an independent appraiser mutually agreed upon by the Servicer and the Holders of a majority in Percentage Interest of the Class A-R-II Certificates in their reasonable discretion, such appraisal to be obtained by the Holders of a majority in Percentage Interest of the Class A-R-II Certificates at their expense, and (A) such appraisal shall be obtained at no expense to the Trustee and (B) the Trustee may conclusively rely on, and shall be protected in relying on, such fair market value determination.

In connection with any such purchase pursuant to the preceding paragraph, the Servicer shall remit to the Trustee for deposit in the Distribution Account all amounts then on deposit in the Collection Account, which deposit shall be deemed to have occurred immediately preceding such purchase.

No such purchase by the Servicer will be permitted without the consent of the Certificate Insurer if a draw on the Certificate Insurance Policy will be made or if any amounts due to the Certificate Insurer would remain unreimbursed on the final Distribution Date.

(b)

Notice of any termination pursuant to the second paragraph of Section 10.01(a), specifying the Distribution Date (which shall be a date that would otherwise be a Distribution Date) upon which the Certificateholders may surrender their Certificates to the Certificate Registrar for payment of the final distribution and cancellation, shall be given promptly by the Trustee upon the Trustee receiving notice of such date from the Servicer by letter to the Certificateholders mailed not earlier than the 10th day and not later than the 19th day of the month immediately preceding the month of such final distribution specifying (1) the Distribution Date upon which final distribution of the Certificates will be made upon presentation and surrender of such Certificates at the office or agency of the Certificate Registrar therein designated, (2) the amount of any such final distribution and (3) that the Record Date otherwise applicable to such Distribution Date is not applicable, distributions being made only upon presentation and surrender of the Certificates at the office or agency of the Certificate Registrar therein specified. The Trustee shall give such notice to the Certificate Insurer and the Certificate Registrar at the time such notice is given to Holders of the Certificates. Upon any such termination, the duties of the Certificate Registrar with respect to the Certificates shall terminate and the Trustee shall terminate the Distribution Account and any other account or fund maintained with respect to the Certificates, subject to the Trustee’s obligation hereunder to hold all amounts payable to Certificateholders in trust without interest pending such payment.

(c)

Upon presentation and surrender of the Certificates, the Trustee shall cause to be distributed to the Holders of the Certificates on the Distribution Date for such final distribution, in proportion to the Percentage Interests of their respective Class and to the extent that funds are available for such purpose, an amount equal to the amount required to be distributed to such Holders in accordance with the provisions of Section 5.01 hereof for such Distribution Date.

(d)

In the event that all Certificateholders shall not surrender their Certificates for final payment and cancellation on or before such final Distribution Date, the Trustee shall promptly following such date cause all funds in the Distribution Account not distributed in final distribution to Certificateholders to be withdrawn therefrom and credited to the remaining Certificateholders by depositing such funds in a separate account for the benefit of such Certificateholders, and the Trustee shall give a second written notice to the remaining Certificateholders to surrender their Certificates for cancellation and receive the final distribution with respect thereto. If within nine months after the second notice all the Certificates shall not have been surrendered for cancellation, the Servicer shall be entitled to all unclaimed funds and other assets which remain subject hereto, and the Trustee upon transfer of such funds shall be discharged of any responsibility for such funds, and the Certificateholders shall look to the Servicer for payment.

In addition, this Agreement may be amended from time to time by Seller, the Depositor, and the Trustee with the consent of the Majority Certificateholders and the Certificate Insurer (if the proposed amendment adversely affects in any respect the rights and interest of the Certificate Insurer) for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Agreement or of modifying in any manner the rights of the Holders of Certificates; and subject, in the case of any amendment or modification to Section 5.01(a) hereof, to the consent of the Bank of New York, as Custodian; provided, however, that no such amendment or waiver shall (x) reduce in any manner the amount of, or delay the timing of, payments on the Certificates that are required to be made on any Certificate without the consent of the Holder of such Certificate, (y) adversely affect in any material respect the interests of the Holders of any Class of Certificates in a manner other than as described in clause (x) above, without the consent of the Holders of Certificates of such Class evidencing at least a 66⅔% Percentage Interest in such Class, or (z) reduce the percentage of Voting Rights required by clause (y) above without the consent of the Holders of all Certificates of such Class then outstanding. Upon approval of an amendment, a copy of such amendment shall be sent to each Rating Agency.

Notwithstanding any provision of this Agreement to the contrary, the Trustee shall not consent to any amendment to (1) this Agreement unless it shall have first received an Opinion of Counsel, delivered by and at the expense of the Person seeking such Amendment (unless such Person is the Trustee, in which case the Trustee shall be entitled to be reimbursed for such expenses by the Trust pursuant to Section 8.05 hereof), to the effect that such amendment will not result in an Adverse REMIC Event and that the amendment is being made in accordance with the terms hereof, such amendment is permitted by this Agreement and all conditions precedent, if any, have been complied with and (2) the Reconstitution Agreement unless it shall first have received the consent of the Certificate Insurer.

Promptly after the execution of any such amendment the Trustee shall furnish, at the expense of the Person that requested the amendment if such Person is the Seller (but in no event at the expense of the Trustee), otherwise at the expense of the Trust, a copy of such amendment and the Opinion of Counsel referred to in the immediately preceding paragraph to the Servicer, the Certificate Insurer and each Rating Agency.

It shall not be necessary for the consent of Certificateholders under this Section 12.01 to approve the particular form of any proposed amendment; instead it shall be sufficient if such consent shall approve the substance thereof. The manner of obtaining such consents and of evidencing the authorization of the execution thereof by Certificateholders shall be subject to such reasonable regulations as the Trustee may prescribe.

The Trustee may, but shall not be obligated to, enter into any amendment pursuant to this 12.01 Section that affects its rights, duties and immunities under this Agreement or otherwise.

SECTION 12.02. Recordation of Agreement; Counterparts.

To the extent permitted by applicable law, this Agreement is subject to recordation in all appropriate public offices for real property records in all the counties or other comparable jurisdictions in which any or all of the Mortgaged Properties are situated, and in any other appropriate public recording office or elsewhere, such recordation to be effected by the Trustee at the expense of the Trust, but only upon direction of Certificateholders accompanied by an Opinion of Counsel to the effect that such recordation materially and beneficially affects the interests of the Certificateholders and the Certificate Insurer.

For the purpose of facilitating the recordation of this Agreement as herein provided and for other purposes, this Agreement may be executed simultaneously in any number of counterparts, each of which counterparts shall be deemed to be an original, and such counterparts shall together constitute but one and the same instrument.

SECTION 12.03. Limitation on Rights of Certificateholders.

The death or incapacity of any Certificateholder shall not (i) operate to terminate this Agreement or the Trust, (ii) entitle such Certificateholder’s legal representatives or heirs to claim an accounting or to take any action or proceeding in any court for a partition or winding up of the Trust or (iii) otherwise affect the rights, obligations and liabilities of the parties hereto or any of them.

Except as expressly provided for herein, no Certificateholder shall have any right to vote or in any manner otherwise control the operation and management of the Trust, or the obligations of the parties hereto, nor shall anything herein set forth or contained in the terms of the Certificates be construed so as to constitute the Certificateholders from time to time as partners or members of an association; nor shall any Certificateholder be under any liability to any third person by reason of any action taken by the parties to this Agreement pursuant to any provision hereof.

No Certificateholder shall have any right by virtue of any provision of this Agreement to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Agreement, unless such Holder previously shall have given to the Trustee a written notice of default and of the continuance thereof, as hereinbefore provided, and unless also the Holders of Certificates entitled to at least 25% of the Voting Rights shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder and shall have offered to the Trustee such reasonable indemnity as it may require against the costs, expenses and liabilities to be incurred therein or thereby, and the Trustee for 15 days after its receipt of such notice, request and offer of indemnity, shall have neglected or refused to institute any such action, suit or proceeding. It is understood and intended, and expressly covenanted by each Certificateholder with every other Certificateholder, and the Trustee, that no one or more Holders of Certificates shall have any right in any manner whatever by virtue of any provision of this Agreement to affect, disturb or prejudice the rights of the Holders of any other of such Certificates, or to obtain or seek to obtain priority over or preference to any other such Holder, which priority or preference is not otherwise provided for herein, or to enforce any right under this Agreement, except in the manner herein provided and for the equal, ratable and common benefit of all Certificateholders. For the protection and enforcement of the provisions of this Section 12.03, each and every Certificateholder and the Trustee shall be entitled to such relief as can be given either at law or in equity.

By accepting its Insured Certificate, each Holder of an Insured Certificate agrees that, unless a Certificate Insurer Default exists and is continuing, the Certificate Insurer shall have the right to exercise all rights of the Holders of the Insured Certificates under this Agreement (other than the right to receive distributions on the Insured Certificates) without any further consent of the Holders of the Insured Certificates and the Holders of the Insured Certificates shall exercise any such rights only upon the written consent of the Certificate Insurer; provided, however, each Holder of an Insured Certificate and the Certificate Insurer will have the right to receive statements and reports hereunder. Notwithstanding the foregoing, the Certificate Insurer shall have no power without the consent of the Owner of each Insured Certificate affected thereby to: (i) reduce in any manner the amount of, or delay the timing of, distributions of principal or interest required to be made hereunder or reduce the Percentage Interest of the Holders of the Insured Certificates, the Certificate Interest Rate or the Termination Payment with respect to any of the Insured Certificates; (ii) reduce the percentage of Percentage Interests specified in Section 12.01 which are required to amend this Agreement; (iii) create or permit the creation of any lien against any part of the Trust Fund; (iv) modify any provision in any way which would permit an earlier retirement of the Insured Certificates; or (v) amend this sentence.

This Certificate is issued under and is subject to the terms, provisions and conditions of the Agreement, to which Agreement the Holder of this Certificate by virtue of the acceptance hereof assents and by which such Holder is bound.

Any distribution of the proceeds of any remaining assets of the Trust Fund will be made only upon presentment and surrender of this Certificate at the Corporate Trust Office of the Certificate Registrar or the office or agency maintained by the Certificate Registrar.

No transfer of this Certificate shall be made unless the Certificate Registrar shall have received either (i) a representation letter from the transferee of such Certificate, acceptable to and in form and substance satisfactory to the Certificate Registrar and the Depositor and in substantially the form attached to the Agreement, to the effect that such transferee is not an employee benefit or other plan or arrangement subject to Section 406 of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”) or Section 4975 of the Internal Revenue Code of 1986, as amended (the “Code”), nor a person acting on behalf or investing plan assets of any such plan or arrangement, which representation letter shall not be an expense of the Certificate Registrar or the Trustee, or (ii) a representation that the purchaser is an insurance company which is purchasing such Certificate with funds contained in an “insurance company general account” (as such term is defined in Section V(e) of Prohibited Transaction Class Exemption (“PTCE”) 95-60) and that the purchase and holding of such Certificate are covered under Sections I and III of PTCE 95-60, or (iii) an Opinion of Counsel in accordance with the provisions of the Agreement. Notwithstanding anything else to the contrary herein, any purported transfer of this Certificate to or on behalf of an employee benefit plan subject to ERISA or to the Code without the opinion of counsel satisfactory to the Certificate Registrar as described above shall be void and of no effect.

The Trustee will provide the Internal Revenue Service and any pertinent persons with the information needed to compute the tax imposed under the applicable tax laws on transfers of residual interests to disqualified organizations, if any person other than a Permitted Transferee acquires an Ownership Interest in this Certificate in violation of the restrictions mentioned above.

COUNTY OF	)

The undersigned, being first duly sworn, deposes and says as follows:

The undersigned is an officer of ______________________, the proposed Transferee of a 100% Ownership Interest in the Class [A-R], [A-R-II] Certificate (the “Certificate”) issued pursuant to the Pooling Agreement, (the “Agreement”) dated as of April 1, 2006, relating to the above-referenced Certificates, among Greenwich Capital Acceptance, Inc., as Depositor, Greenwich Capital Financial Products, Inc., as Seller, and U.S. Bank National Association, as Trustee. Capitalized terms used, but not defined herein, shall have the meanings ascribed to such terms in the Agreement. The Transferee has authorized the undersigned to make this affidavit on behalf of the Transferee.

The Transferee is, as of the date hereof, and will be, as of the date of the Transfer, a Permitted Transferee. The Transferee is acquiring its Ownership Interest for its own account and not in a capacity as trustee, nominee or agent for another party.

The Transferee has been advised of, and understands that (i) a tax will be imposed on Transfers of the Certificate to Persons that are not Permitted Transferees; (ii) such tax will be imposed on the transferor, or, if such Transfer is through an agent (which includes a broker, nominee or middleman) for a Person that is not a Permitted Transferee, on the agent; and (iii) the Person otherwise liable for the tax shall be relieved of liability for the tax if the subsequent Transferee furnished to such Person an affidavit that such subsequent Transferee is a Permitted Transferee and, at the time of Transfer, such Person does not have actual knowledge that the affidavit is false. The Transferee has provided financial statements or other financial information requested by the Transferor in connection with the transfer of the Certificate to permit the Transferor to assess the financial capability of the Transferee to pay such taxes.

The Transferee has been advised of, and understands that a tax may be imposed on a “pass-through entity” holding the Certificate if, at any time during the taxable year of the pass-through entity, a Disqualified Organization is the record holder of an interest in such entity. The Transferee understands that such tax will not be imposed for any period with respect to which the record holder furnishes to the pass-through entity an affidavit that such record holder is not a Disqualified Organization and the pass-through entity does not have actual knowledge that such affidavit is false. (For this purpose, a “pass-through entity” includes a regulated investment company, a real estate investment trust or common trust fund, a partnership, trust or estate, and certain cooperatives and, except as may be provided in Treasury Regulations, persons holding interests in pass-through entities as a nominee for another Person.)

The Transferee has reviewed the provisions of Section 6.02(e) of the Agreement and understands the legal consequences of the acquisition of an Ownership Interest in the Certificate including, without limitation, the restrictions on subsequent Transfers and the provisions regarding voiding the Transfer and mandatory sales. The Transferee expressly agrees to be bound by and to abide by the provisions of Section 6.02(e) of the Agreement and the restrictions noted on the face of the Certificate. The Transferee understands and agrees that any breach of any of the representations included herein shall render the Transfer to the Transferee contemplated hereby null and void.

The Transferee agrees to require a Transfer Affidavit from any Person to whom the Transferee attempts to Transfer its Ownership Interest in the Certificate, and the Transferee will not Transfer its Ownership Interest or cause any Ownership Interest to be Transferred to any Person that the Transferee knows is not a Permitted Transferee. In connection with any such Transfer by the Transferee, the Transferee agrees to deliver to the Trustee a certificate substantially in the form set forth as Exhibit K to the Agreement (a “Transferor Certificate”).

The Transferee does not have the intention to impede the assessment or collection of any tax legally required to be paid with respect to the Certificate.

The Transferee’s taxpayer identification number is .

The Transferee is aware that the Certificate may be a “noneconomic residual interest” within the meaning of the REMIC provisions and that the transferor of a noneconomic residual interest will remain liable for any taxes due with respect to the income on such residual interest, unless no significant purpose of the transfer was to impede the assessment or collection of tax.

IN WITNESS WHEREOF, the Transferee has caused this instrument to be executed on its behalf, pursuant to authority of its Board of Directors, by its duly authorized officer and its corporate seal to be hereunto affixed, duly attested, this day of , 20 .
