The Trustee or the Securities Administrator may conclusively rely upon a certificate of the Depositor, the Seller or the Master Servicer in determining whether a Certificate is held by an Affiliate thereof. All references herein to “Holders” or “Certificateholders” shall reflect the rights of Certificate Owners as they may indirectly exercise such rights through the Depository and participating members thereof, except as otherwise specified herein; provided, however, that the Trustee or the Securities Administrator shall be required to recognize as a “Holder” or “Certificateholder” only the Person in whose name a Certificate is registered in the Certificate Register.

For the month of substitution, distributions to Certificateholders shall reflect the Monthly Payment due on such Deleted Loan on or before the Due Date in the month of substitution, and the Seller shall thereafter be entitled to retain all amounts subsequently received in respect of such Deleted Loan. The Depositor shall give or cause to be given written notice to the Certificateholders that such substitution has taken place, shall amend the Loan Schedule to reflect the removal of such Deleted Loan from the terms of this Agreement and the substitution of the Substitute Loan or Loans and shall deliver a copy of such amended Loan Schedule to the Trustee and the Master Servicer. Upon such substitution, such Substitute Loan or Loans shall constitute part of the Trust Fund and shall be subject in all respects to the terms of this Agreement and the Mortgage Loan Purchase Agreement including all applicable representations and warranties thereof included herein or in the Mortgage Loan Purchase Agreement.

For any month in which the Seller substitutes one or more Substitute Loans for one or more Deleted Loans, the Master Servicer shall determine the amount (the “Substitution Shortfall Amount”), if any, by which the aggregate Purchase Price of all such Deleted Loans exceeds the aggregate of, as to each such Substitute Loan, the Scheduled Principal Balance thereof as of the Due Date in the month of substitution, together with one month’s interest on such Scheduled Principal Balance at the applicable Net Mortgage Rate, plus all outstanding Advances and Servicing Advances (including Nonrecoverable Advances) related thereto. On the date of such substitution, the Seller shall deliver or cause to be delivered to the Securities Administrator for deposit in the Distribution Account an amount equal to the Substitution Shortfall Amount, if any, and the Trustee or the Custodian on behalf of the Trustee, upon receipt of the related Substitute Loan or Loans and certification by the Securities Administrator of such deposit and receipt by the Custodian of a properly completed request for release for such Loan in the form of Exhibit 3 to the Custodial Agreement, shall release to the Seller the related Mortgage File or Files and the Trustee shall execute and deliver such instruments of transfer or assignment, in each case without recourse, representation or warranty, as the Seller shall deliver to it and as shall be necessary to vest therein any Deleted Loan released pursuant hereto.

In addition, the Seller shall obtain at its own expense and deliver to the Trustee, the Securities Administrator and the Depositor an Opinion of Counsel to the effect that such substitution will not cause (a) any federal tax to be imposed on any REMIC, including without limitation, any federal tax imposed on “prohibited transactions” under Section 860F(a)(1) of the Code or on “contributions after the startup date” under Section 860G(d)(1) of the Code, or (b) any REMIC to fail to qualify as a REMIC at any time that any Certificate is outstanding.

(c) Upon discovery by the Depositor, the Seller, the Master Servicer or the Trustee that any 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 (2) Business Days give written notice thereof to the other parties. In connection therewith, the Seller shall repurchase or substitute one or more Substitute Loans for the affected Loan within ninety (90)

days of the earlier of discovery or receipt of such notice with respect to such affected Loan. Such repurchase or substitution shall be made by (i) the Seller, if the affected Loan’s status as a non-qualified mortgage is or results from a breach of any representation, warranty or covenant made by the Seller under the Mortgage Loan Purchase Agreement or (ii) the Depositor, if the affected Loan’s status as a non-qualified mortgage does not result from a breach of representation or warranty. Any such repurchase or substitution shall be made in the same manner as set forth in Section 2.3(a). The Trustee shall reconvey to the Seller or the Depositor the Loan to be released pursuant hereto in the same manner, and on the same terms and conditions, as it would a Loan repurchased for breach of a representation or warranty.

(d) Within ninety (90) days of the earlier of discovery by the Master Servicer or receipt of notice by the Master Servicer of the breach of any representation, warranty or covenant of the Master Servicer set forth in Section 2.5 which materially and adversely affects the interests of the related Certificateholders in any Loan or Prepayment Charge, the Master Servicer shall cure such breach in all material respects.

Section 2.4 Authentication and Delivery of Certificates; Designation of Certificates as REMIC Regular and Residual Interests.

(a) The Trustee acknowledges the transfer to the extent provided herein and assignment to it of the Trust Fund and, concurrently with such transfer and assignment, has caused the Securities Administrator to execute and authenticate and has delivered to or upon the order of the Depositor, in exchange for the Trust Fund, Certificates evidencing the entire ownership of the Trust Fund.

(b) This Agreement shall be construed so as to carry out the intention of the parties that each of REMIC I, REMIC II and REMIC III be treated as a REMIC at all times prior to the date on which the Trust Fund is terminated. The “regular interests” (within the meaning of Section 860G(a)(1) of the Code) in REMIC III shall consist of the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-6, Class A-7, Class A-X2, Class P, Class M, Class B-1, Class B-2, Class B-3, Class B-4 and Class B-5 Certificates and the Class A-X1A-1 Component and Class A-X1A-2 Component (each component beneficially owned by the Class A-X1A Certificates) and the Class A-X1B-1 Component, Class A-X1B-2 Component, Class A-X1B-3 Component, Class A-X1B-4 Component, Class A-X1B-5 Component, Class A-X1B-6 Component and Class A-X1B-7 Component (each component beneficially owned by the Class A-X1B Certificates). The “residual interest” (within the meaning of Section 860G(a)(2) of the Code) in REMIC III shall consist of Component R-3. The “regular interests” (within the meaning of Section 860G(a)(1) of the Code) of REMIC II shall consist of the REMIC II Regular Interests. The “residual interest” (within the meaning of Section 860(G)(a)(2) of the Code) of REMIC II shall consist of Component R-2. The “regular interests” (within the meaning of Section 860G(a)(1) of the Code) of REMIC I shall consist of the REMIC I Regular Interests. The “residual interest” (within the meaning of Section 860(G)(a)(2) of the Code) of REMIC I shall consist of Component R-1.

ARTICLE III

ADMINISTRATION AND SERVICING OF THE LOANS; ACCOUNTS

Section 3.1 Master Servicer. The Master Servicer shall supervise, monitor and oversee the obligation of the Servicers to service and administer their respective Loans in accordance with the terms of the applicable Servicing Agreement and shall have full power and authority to do any and all things which it may deem necessary or desirable in connection with such master servicing and administration. In performing its obligations hereunder, the Master Servicer shall act in a manner consistent with Accepted Master Servicing Practices. Furthermore, the Master Servicer shall oversee and consult with each Servicer as necessary from time-to-time to carry out the Master Servicer’s obligations hereunder, shall receive, review and evaluate all reports, information and other data provided to the Master Servicer by each Servicer and shall cause each Servicer to perform and observe the covenants, obligations and conditions to be performed or observed by such Servicer under the applicable Servicing Agreement. The Master Servicer shall independently and separately monitor each Servicer’s servicing activities with respect to each related Loan, reconcile the results of such monitoring with such information provided in the previous sentence on a monthly basis and coordinate corrective adjustments to the Servicers’ and Master Servicer’s records, and based on such reconciled and corrected information, prepare the statements specified in Section 4.6 and any other information and statements required to be provided by the Master Servicer hereunder. The Master Servicer shall reconcile the results of its Loan monitoring with the actual remittances of the Servicers to the Distribution Account pursuant to the applicable Servicing Agreements.

Notwithstanding anything in this Agreement or any Servicing Agreement to the contrary, the Master Servicer shall not have any duty or obligation to enforce any Credit Risk Management Agreement that a Servicer is a party to (a “Servicer Credit Risk Management Agreement”) or to supervise, monitor or oversee the activities of the Credit Risk Manager under any such Servicer Credit Risk Management Agreement with respect to any action taken or not taken by the applicable Servicer pursuant to a recommendation of the Credit Risk Manager.

The Trustee shall furnish the Servicers and the Master Servicer with any limited powers of attorney and other documents in form as provided to it necessary or appropriate to enable the Servicers and the Master Servicer to service or master service and administer the related Loans and REO Property. The Trustee shall have no responsibility for any action of the Master Servicer or any Servicer pursuant to any such limited power of attorney and shall be indemnified by the Master Servicer or such Servicer for any cost, liability or expense arising from the misuse thereof by the Master Servicer or such Servicer.

The Trustee, the Custodian and the Securities Administrator shall provide access to the records and documentation in possession of the Trustee, the Custodian or the Securities Administrator regarding the related Loans and REO Property and the servicing thereof to the Certificateholders, the FDIC, and the supervisory agents and examiners of the FDIC, such access being afforded only upon reasonable prior written request and during normal business hours at the office of the Trustee, the Custodian or the Securities Administrator; provided, however, that, unless otherwise required by law, none of the Trustee, the Custodian or the Securities Administrator shall be required to provide access to such records and documentation if the provision thereof would violate the legal right to privacy of any Mortgagor. The Trustee, the

Custodian and the Securities Administrator shall allow representatives of the above entities to photocopy any of the records and documentation and shall provide equipment for that purpose at a charge that covers the Trustee’s, the Custodian’s or the Securities Administrator’s actual costs.

The Trustee shall execute and deliver to the related Servicer or the Master Servicer upon request any court pleadings, requests for trustee’s sale or other documents necessary or desirable and, in each case, provided to the Trustee by such Servicer or Master Servicer to (i) the foreclosure or trustee’s sale with respect to a Mortgaged Property, (ii) any legal action brought to obtain judgment against any Mortgagor on the Mortgage Note or any other Loan Document, (iii) obtain a deficiency judgment against the Mortgagor, or (iv) enforce any other rights or remedies provided by the Mortgage Note or any other Loan Document or otherwise available at law or equity.

Section 3.2 REMIC-Related Covenants. For as long as each REMIC shall exist, the Trustee and the Securities Administrator shall treat each REMIC as a REMIC, and the Trustee and the Securities Administrator shall comply with any directions of the Seller, the related Servicer or the Master 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 Loans or of any investment of deposits in an Account unless such sale is as a result of a repurchase of the Loans pursuant to this Agreement or the Trustee has received an Opinion of Counsel stating that such sale will not result in an Adverse REMIC Event as defined in Section 10.1(f) hereof prepared at the expense of the Trust Fund, and (b) other than with respect to a substitution pursuant to the Mortgage Loan Purchase Agreement, the Assignment Agreements or Section 2.3 of this Agreement, as applicable, accept any contribution to any REMIC after the Startup Day without receipt of an Opinion of Counsel stating that such contribution will not result in an Adverse REMIC Event as defined in Section 10.1(f) hereof.

Section 3.3 Monitoring of Servicers. (a) The Master Servicer shall be responsible for monitoring the compliance by each Servicer with its duties under the related Servicing Agreement. In the review of each Servicer’s activities, the Master Servicer may rely upon an officer’s certificate of any Servicer with regard to such Servicer’s compliance with the terms of its Servicing Agreement. In the event that the Master Servicer, in its judgment, determines that a Servicer should be terminated in accordance with its Servicing Agreement, or that a notice should be sent pursuant to such Servicing Agreement with respect to the occurrence of an event that, unless cured, would constitute grounds for such termination, the Master Servicer shall notify the Seller and the Trustee thereof and the Master Servicer shall issue such notice or take such other action as it deems appropriate.

(b) The Master Servicer, for the benefit of the Trustee and the Certificateholders, shall enforce the obligations of each Servicer under the related Servicing Agreement, and shall, in the event that a Servicer fails to perform its obligations in accordance with the related Servicing Agreement, subject to the preceding paragraph, terminate the rights and obligations of such Servicer thereunder and act as servicer of the related Loans or to cause the Trustee to enter in to a new Servicing Agreement with a successor servicer selected by the Master Servicer; provided, however, it is understood and acknowledged by the parties hereto that there will be a period of transition (not to exceed ninety (90) days) before the actual servicing functions can be fully transferred to such successor servicer. Such enforcement, including,

without limitation, the legal prosecution of claims, termination of Servicing Agreements and the pursuit of other appropriate remedies, shall be in such form and carried out to such an extent and at such time as the Master Servicer, in its good faith business judgment, would require were it the owner of the related Loans. The Master Servicer shall pay the costs of such enforcement at its own expense, provided that the Master Servicer shall not be required to prosecute or defend any legal action except to the extent that the Master Servicer shall have received indemnity reasonably acceptable to it for its costs and expenses in pursuing such action.

(c) To the extent that the costs and expenses of the Master Servicer related to any termination of an a Servicer, appointment of a successor servicer or the transfer and assumption of servicing by the Master Servicer with respect to any Servicing Agreement (including, without limitation, (i) all legal costs and expenses and all due diligence costs and expenses associated with an evaluation of the potential termination of the related Servicer as a result of an event of default by such Servicer and (ii) all costs and expenses associated with the complete transfer of servicing, including all servicing files and all servicing data and the completion, correction or manipulation of such servicing data as may be required by the successor servicer to correct any errors or insufficiencies in the servicing data or otherwise to enable the successor servicer to service the Loans in accordance with the related Servicing Agreement) are not fully and timely reimbursed by the terminated Servicer, the Master Servicer shall be entitled to reimbursement of such costs and expenses from the Distribution Account.

(d) The Master Servicer shall require each Servicer to comply with the remittance requirements and other obligations set forth in the related Servicing Agreement.

(e) If the Master Servicer acts as Servicer, it shall not assume liability for the representations and warranties of the Servicer, if any, that it replaces.

Section 3.4 Fidelity Bond. The Master Servicer, at its expense, shall maintain in effect a blanket fidelity bond and an errors and omissions insurance policy that would meet the requirements of Xxxxxx Xxx or Xxxxxxx Mac, affording coverage with respect to all directors, officers, employees and other Persons acting on such Master Servicer’s behalf, and covering errors and omissions in the performance of the Master Servicer’s obligations hereunder. The errors and omissions insurance policy and the fidelity bond shall be in such form and amount generally acceptable for entities serving as master servicers or trustees. Any such errors and omissions policy and fidelity bond may not be cancelable without thirty (30) days’ prior written notice to the Trustee.

Section 3.5 Power to Act; Procedures. The Master Servicer shall master service the Loans and shall have full power and authority, subject to the REMIC Provisions and the provisions of Article X hereof, to do any and all things that it may deem necessary or desirable in connection with the master servicing and administration of the Loans, including but not limited to the power and authority (i) to execute and deliver, on behalf of the Certificateholders and the Trustee, customary consents or waivers and other instruments and documents, (ii) to consent to transfers of any Mortgaged Property and assumptions of the Mortgage Notes and related Mortgages, (iii) to collect any Insurance Proceeds and Liquidation Proceeds, and (iv) to effectuate foreclosure or other conversion of the ownership of the Mortgaged Property securing any Loan, in each case, in accordance with the provisions of this

Agreement and the related Servicing Agreement, as applicable; provided, however, that the Master Servicer shall not (and, consistent with its responsibilities under Section 3.3, shall not permit any Servicer to) knowingly or intentionally take any action, or fail to take (or fail to cause to be taken) any action reasonably within its control and the scope of duties more specifically set forth herein, that, under the REMIC Provisions, if taken or not taken, as the case may be, would cause any REMIC to fail to qualify as a REMIC or result in the imposition of a tax upon the Trust Fund (including but not limited to the tax on prohibited transactions as defined in Section 860F(a)(2) of the Code and the tax on contributions to a REMIC set forth in Section 860G(d) of the Code) unless the Master Servicer has received an Opinion of Counsel (but not at the expense of the Master Servicer) to the effect that the contemplated action will not cause any REMIC to fail to qualify as a REMIC or result in the imposition of a tax upon any REMIC. The Trustee shall furnish the Master Servicer, upon written request from a Servicing Officer, with any powers of attorney empowering the Master Servicer or the related Servicer to execute and deliver instruments of satisfaction or cancellation, or of partial or full release or discharge, and to foreclose upon or otherwise liquidate Mortgaged Property, and to appeal, prosecute or defend in any court action relating to the Loans or the Mortgaged Property, in accordance with the applicable Servicing Agreement and this Agreement, and the Trustee shall execute and deliver such other documents, as the Master Servicer or the related Servicer may request, to enable the Master Servicer to master service and administer the Loans and carry out its duties hereunder, in each case in accordance with Accepted Master Servicing Practices (and the Trustee shall have no liability for the misuse of any such powers of attorney by the Master Servicer or any Servicer and shall be indemnified by the Master Servicer or such Servicer for any costs, liabilities or expenses incurred by the Trustee in connection with such misuse). If the Master Servicer or the Trustee has been advised that it is likely that the laws of the state in which action is to be taken prohibit such action if taken in the name of the Trustee or that the Trustee would be adversely affected under the “doing business” or tax laws of such state if such action is taken in its name, the Master Servicer shall join with the Trustee in the appointment of a co-trustee pursuant to Section 8.10 hereof. In the performance of its duties hereunder, the Master Servicer shall be an independent contractor and shall not, except in those instances where it is taking action authorized pursuant to this Agreement to be taken by it in the name of the Trustee, be deemed to be the agent of the Trustee.

Section 3.6 Due-on-Sale Clauses; Assumption Agreements. To the extent provided in the applicable Servicing Agreement and to the extent Loans contain enforceable due-on-sale clauses, the Master Servicer shall cause the Servicers to enforce such clauses in accordance with the applicable Servicing Agreement. If applicable law prohibits the enforcement of a due-on-sale clause or such clause is otherwise not enforced in accordance with the applicable Servicing Agreement, and, as a consequence, a Loan is assumed, the original Mortgagor may be released from liability in accordance with the applicable Servicing Agreement.

Section 3.7

Release of Mortgage Files.

(a) Upon becoming aware of Payoff with respect to any Loan, or the receipt by any 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 applicable Servicer will (or if the applicable Servicer does not, the Master Servicer may), if required under

the applicable Servicing Agreement, promptly furnish to the Custodian, on behalf of the Trustee, two copies of a request for release substantially in the form attached to the Custodial Agreement, and 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 Protected Account maintained by the applicable Servicer pursuant to its Servicing Agreement have been or will be so deposited) and shall request that the Custodian, on behalf of the Trustee, deliver to the applicable Servicer the related Mortgage File. Upon receipt of such certification and request, the Custodian, on behalf of the Trustee, shall promptly release the related Mortgage File to the applicable Servicer and the Trustee and Custodian shall have no further responsibility with regard to such Mortgage File. Upon any such Payoff, each Servicer is authorized to give, as agent for the Trustee, as the mortgagee under the Mortgage that secured the 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 Distribution Account.

(b) From time to time and as appropriate for the servicing or foreclosure of any Loan and in accordance with the applicable Servicing Agreement, the Trustee shall execute such documents as shall be prepared and furnished to the Trustee by a Servicer or the Master Servicer (in form reasonably acceptable to the Trustee) and as are necessary to the prosecution of any such proceedings. The Custodian, on behalf of the Trustee, shall, upon the request of a Servicer or the Master Servicer, and delivery to the Custodian, on behalf of the Trustee, of two copies of a request for release signed by a Servicing Officer substantially in the form attached to the Custodial Agreement (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 related Servicer or the Master Servicer, as applicable. Such request for release shall obligate the related Servicer or the Master Servicer to return the Mortgage File to the Custodian on behalf of the Trustee, when the need therefor by such Servicer or the Master Servicer no longer exists unless the 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, on behalf of the Trustee, to such Servicer or the Master Servicer.

Section 3.8 Documents, Records and Funds in Possession of Master Servicer To Be Held for Trustee.

Section 3.28

Prepayment Penalty Verification.

On or prior to each Servicer Remittance Date, each Servicer shall, to the extent provided in the respective Servicing Agreement, provide in an electronic format acceptable to the Master Servicer the data necessary for the Master Servicer to perform its verification duties agreed to by the Master Servicer and the Depositor. The Master Servicer or a third party reasonably acceptable to the Master Servicer and the Depositor (the “Verification Agent”) will perform such verification duties and will use its best efforts to issue its findings in a report (the “Verification Report”) delivered to the Master Servicer and the Depositor within ten (10) Business Days following the related Distribution Date; provided, however, that if the Verification Agent is unable to issue the Verification Report within ten (10) Business Days following the Distribution Date, the Verification Agent may issue and deliver to the Master Servicer and the Depositor the Verification Report upon the completion of its verification duties. The Master Servicer shall forward the Verification Report to the respective Servicer and shall notify such Servicer if the Master Servicer has determined that such Servicer did not deliver the appropriate Prepayment Charges to the Master Servicer in accordance with the respective Servicing Agreement. Such written notification from the Master Servicer shall include the loan number, prepayment penalty code and prepayment penalty amount as calculated by the Master Servicer or the Verification Agent, as applicable, of each Loan for which there is a discrepancy. If the respective Servicer agrees with the verified amounts, such Servicer shall adjust the immediately succeeding Remittance Report and the amount remitted to the Master Servicer with respect to prepayments accordingly. If the respective Servicer disagrees with the determination of the Master Servicer, such Servicer shall, within five (5) Business Days of its receipt of the Verification Report, notify the Master Servicer of such disagreement and provide the Master Servicer with detailed information to support such Servicer’s position. The respective Servicer and the Master Servicer shall cooperate to resolve any discrepancy on or prior to the immediately succeeding Servicer Remittance Date, and such Servicer will indicate the effect of such resolution on the related Remittance Report and shall adjust the amount remitted with respect to prepayments on such Servicer Remittance Date accordingly.

During such time as the respective Servicer and the Master Servicer are resolving discrepancies with respect to the Prepayment Charges, no payments in respect of any disputed Prepayment Charges will be remitted to the Distribution Account and the Master Servicer shall not be obligated to remit such payments, unless otherwise required pursuant to Section 7.1 hereof. In connection with such duties, the Master Servicer shall be able to rely solely on the information provided to it by the respective Servicer in accordance with this Section. The Master Servicer shall not be responsible for verifying the accuracy of any of the information provided to it by the respective Servicer or for performing the Master Servicer’s duties under this Section 3.28 with respect to a Servicer if such Servicer is unable or unwilling to provide the required data to the Master Servicer or is not required to provide such information to the Master Servicer.

(4)

fourth, from the Available Distribution Amount remaining after payments pursuant to clauses (1) through (3) above, to the Reserve Fund and then from the Reserve Fund, concurrently to the Senior Certificates (other than the Class A-X1A, Class A-X1B, Class A-X2 and Class R Certificates) on a pro rata basis based on the Certificate Principal Balance of each such Class, the related Net WAC Rate Carryover Amount payable to each such Class for such Distribution Date;

(5)

On each Distribution Date, all amounts representing Prepayment Charges in respect of the Loans received during the related Prepayment Period will be withdrawn from the Distribution Account and distributed to the Class P Certificates and shall not be available for distribution to the holders of any other Class of Certificates. The payment of such Prepayment Charges shall not reduce the Certificate Principal Balance of the Class P Certificates.

On the Distribution Date in September 2010, the Securities Administrator shall make a payment of principal to the Class P Certificates in reduction of the Certificate Principal Balance thereof from amounts on deposit in a sub-account of the Distribution Account

established and maintained by the Securities Administrator, on behalf of the Trustee, for the exclusive benefit of the Class P Certificateholders.

Section 4.2

Allocation Realized Losses.

(a) Prior to each Distribution Date, the Master Servicer, based solely on the information provided by the related Servicer, shall determine the amount of Realized Losses, if any, with respect to each Loan.

(b) Realized Losses, other than Excess Losses, shall be allocated as follows: (i) for losses allocable to principal, (a) first, sequentially, to the Class B-5, Class B-4, Class B-3, Class B-2, Class B-1 and Class M Certificates, in that order, until the Certificate Principal Balance of each such Class been reduced to zero and (b) second, concurrently to the Senior Certificates (other than the Class A-X1A, Class A-X1B and Class A-X2 Certificates), on a pro rata basis based on the Certificate Principal Balance of each such Class, until the Certificate Principal Balance of each such Class has been reduced to zero; provided, that the pro rata portion of any such Realized Loss allocable to the Class A-6 Certificates will be allocated first to the Class A-7 Certificates, until the Certificate Principal Balance of the Class A-7 Certificates has been reduced to zero, and (ii) for losses allocable to interest, (a) first, sequentially, to the Class B-5, Class B-4, Class B-3, Class B-2, Class B-1 and Class M Certificates, in that order, in reduction of accrued but unpaid interest thereon until the amount of interest accrued on such Certificate on such Distribution Date has been reduced to zero, and then in reduction of the Certificate Principal Balance of such Certificate until the Certificate Principal Balance thereof has been reduced to zero, and (b) second, to the Senior Certificates, by Pro Rata Allocation, in reduction of accrued but unpaid interest thereon until the amount of interest accrued on such Certificate has been reduced to zero and then with respect to the Senior Certificates (other than the Class A-X1A, Class A-X1B and Class A-X2 Certificates), in reduction of the Certificate Principal Balance of each such Certificate until the aggregate of the Certificate Principal Balances thereof have been reduced to zero; provided that the Pro Rata Allocation of any such Realized Loss allocable to the Class A-6 Certificates will be allocated first to the Class A-7 Certificates, until the Certificate Principal Balance of the Class A-7 Certificates has been reduced to zero. In addition, to the extent the related Servicer receives Subsequent Recoveries with respect to any defaulted Loan, the amount of the Realized Loss with respect to that defaulted Loan will be reduced to the extent such Subsequent Recoveries are applied to reduce the Certificate Principal Balance of any Class of Certificates on any Distribution Date. In the event that a Servicer receives any Subsequent Recoveries, such Subsequent Recoveries shall be distributed as part of the Available Distribution Amount, in accordance with the priorities in Section 4.1, and the Certificate Principal Balance of each Class of Subordinate Certificates that has been reduced by the allocation of a Realized Loss to such Certificate shall be increased, in order of seniority, by the amount of such Subsequent Recoveries. Holders of such Certificates are not entitled to any payment in respect of current interest on the amount of such increases for any Interest Accrual Period preceding the Distribution Date on which such increase occurs.

(c) Excess Losses with respect to the Loans will be allocated to the outstanding Class or Classes of Senior Certificates (other than the Class A-X1A, Class A-X1B and Class A-X2 Certificates) and to the Subordinate Certificates by Pro Rata Allocation; provided, that the pro rata portion of any such Realized Loss allocable to the Class A-6

Certificates will be allocated first to the Class A-7 Certificates until the Certificate Principal Balance of the Class A-7 Certificates has been reduced to zero.

(d) On each Distribution Date, if the aggregate Certificate Principal Balance of the Senior Certificates (other than the Class A-X1A, Class A-X1B and Class A-X2 Certificates) and Subordinate Certificates exceeds the aggregate Principal Balance of the Loans (after giving effect to distributions of principal and the allocation and reimbursement of all losses on the Certificates on such Distribution Date), such excess will be deemed a principal loss and will be allocated to the Subordinate Certificates in reverse order of seniority until the Certificate Principal Balance of each such Class has been reduced to zero. If the Certificate Principal Balance of each Subordinate Certificate has been reduced to zero and the aggregate Certificate Principal Balance of the Senior Certificates (other than the Class A-X1A, Class A-X1B and Class A-X2 Certificates) exceeds the aggregate Principal Balance of the Loans (after giving effect to distributions of principal and the allocation and reimbursement of all losses on the Certificates on such Distribution Date), such excess will be deemed a principal loss and, will be allocated to the Senior Certificates (other than the Class A-X1A, Class A-X1B and Class A-X2 Certificates) by Pro Rata Allocation, until the Certificate Principal Balance of each such Class has been reduced to zero; provided, that the Pro Rata Allocation of such loss allocable to the Class A-6 Certificates will be allocated first to the Class A-7 Certificates until the Certificate Principal Balance of the Class A-7 Certificates has been reduced to zero.

(e) Realized Losses from the Loans shall be applied after all distributions have been made on each Distribution Date, to the following REMIC I Regular Interests: first, to REMIC I Regular Interest LT-1 until the Uncertificated Principal Balance thereof has been reduced to zero, then to REMIC I Regular Interest LT-PF until the Uncertificated Principal Balance thereof has been reduced to zero, however, with respect to the first Distribution Date, Realized Losses relating to the Initial Loans shall be allocated to REMIC I Regular Interest LT-1 and Realized Losses relating to the Subsequent Loans shall be allocated to REMIC I Regular Interest LT-PF until the Uncertificated Principal Balance thereof has been reduced to zero.

Realized Losses from the Loans shall be applied after all distributions have been made on each Distribution Date, to each REMIC II Regular Interest in the same manner and priority as Realized Losses are allocated to the Corresponding Certificates.

Section 4.3

Reduction of Certificate Principal Balances on the Certificates.

(a) All reductions in the Certificate Principal Balance of a Certificate effected by distributions of principal or allocations of Realized Losses with respect to the related Loans made on any Distribution Date shall be binding upon all Holders of such Certificate and of any Certificate issued upon the registration of transfer or exchange therefor or in lieu thereof, whether or not such distribution is noted on such Certificate. Holders of such Certificates will not be entitled to any payment in respect of current interest on the amount of such increases for any Interest Accrual Period preceding the Distribution Date on which such increase occurs.

(b) The final distribution of principal of each Certificate (and the final distribution with respect to the Residual Certificates upon termination of the Trust Fund) shall be payable in the manner provided above only upon presentation and surrender thereof on or after

the Distribution Date therefor at the office or agency of the Securities Administrator specified in the notice delivered pursuant to Section 4.6 or Section 9.1.

(c) Whenever, on the basis of Curtailments, Payoffs and Monthly Payments on the Loans and related Insurance Proceeds and Liquidation Proceeds received and expected to be received during the applicable Prepayment Period, the Securities Administrator believes that the entire remaining unpaid aggregate Certificate Principal Balance of any Class of Certificates shall become distributable on the next Distribution Date, the Securities Administrator shall, no later than the Determination Date of the month of such Distribution Date, mail or cause to be mailed to each Person in whose name a Certificate to be so retired is registered at the close of business on the Record Date, to the Underwriter and to each Rating Agency a notice to the effect that:

(i) it is expected that funds sufficient to make such final distribution shall be available in the Distribution Account on such Distribution Date, and

(ii) if such funds are available, (A) such final distribution shall be payable on such Distribution Date, but only upon presentation and surrender of such Certificate at the office or agency of the Securities Administrator maintained for such purpose (the address of which shall be set forth in such notice), and (B) no interest shall accrue on such Certificate after such Distribution Date.

Section 4.4

Compliance with Withholding Requirements.

Notwithstanding any other provision of this Agreement, the Trustee and the Securities Administrator shall comply with all federal withholding requirements respecting payments to Certificateholders of interest or original issue discount that the Trustee and the Securities Administrator reasonably believe are applicable under the Code. The consent of Certificateholders shall not be required for such withholding. In the event the Securities Administrator does withhold any amount from interest or original issue discount payments or advances thereof to any Certificateholder pursuant to federal withholding requirements, the Securities Administrator shall indicate the amount withheld to such Certificateholders.

Section 4.5

Distributions on the Uncertificated REMIC Regular Interests.

Distributions of principal from the Loans shall be deemed to be made to the REMIC I Regular Interests, first, to REMIC I Regular Interest LT-1 until the Uncertificated Principal Balance of such REMIC I Regular Interest is reduced to zero; second, to REMIC I Regular Interest LT-PF, until the Uncertificated Principal Balance of such REMIC I Regular Interest is reduced to zero, however, with respect to the first Distribution Date, distributions of principal relating to the Initial Loans shall be allocated to REMIC I Regular Interest LT-1 and distributions of principal relating to the Subsequent Loans shall be allocated to REMIC I Regular Interest LT-PF. Interest shall be payable to each REMIC I Regular Interest at the related Uncertificated REMIC I Pass-Through Rate on each such REMIC I Regular Interest’s Uncertificated Principal Balance. Any remaining amount to the Class R Certificates (with respect to Component R-1).

On the Distribution Date immediately following the expiration of the latest Prepayment Charge term as identified on the Prepayment Charge Schedule, $100 shall be deemed distributed in respect of REMIC I Regular Interest LT-P in reduction of the Uncertificated Principal Balance thereof.

Distributions of principal from the Loans shall be deemed to be made to REMIC II Regular Interest MT-A1, REMIC II Regular Interest MT-A2, REMIC II Regular Interest MT-A3, REMIC II Regular Interest MT-A4, REMIC II Regular Interest MT-A5, REMIC II Regular Interest MT-A6, REMIC II Regular Xxxxxxxx XX-X0, REMIC II Regular Interest MT-R, REMIC II Regular Interest MT-P, REMIC II Regular Interest MT-M, REMIC II Regular Interest MT-B1, REMIC II Regular Interest MT-B2, REMIC II Regular Interest MT-B3, REMIC II Regular Interest MT-B4 and REMIC II Regular Interest MT-B5 in the same manner and priority as such distributions are made to the Corresponding Certificates. Interest shall be payable to each REMIC II Regular Interest at the related Uncertificated REMIC II Pass-Through Rate on each such REMIC II Regular Interest’s Uncertificated Principal Balance. Any remaining amount to the Class R Certificates (with respect to Component R-2).

In the case of information furnished pursuant to subclause (i) above, the amounts shall be expressed as a dollar amount per single Certificate of the relevant Class.

Within a reasonable period of time after the end of each calendar year, the Securities Administrator shall furnish to each Person who at any time during the calendar year was a Holder of a Regular Interest Certificate a statement containing the information set forth in subclause (i) above, aggregated for such calendar year or applicable portion thereof during which such person was a Certificateholder. Such obligation of the Securities Administrator shall be deemed to have been satisfied to the extent that substantially comparable information shall be provided by the Securities Administrator pursuant to any requirements of the Code as from time to time are in force.

Within a reasonable period of time after the end of each calendar year, the Securities Administrator shall furnish to each Person who at any time during the calendar year was a Holder of a Class R Certificate a statement setting forth the amount, if any, actually distributed with respect to the Class R Certificates aggregated for such calendar year or applicable portion thereof during which such Person was a Certificateholder.

The Securities Administrator shall, upon request, furnish to each Certificateholder, during the term of this Agreement, such periodic, special, or other reports or information, whether or not provided for herein, as shall be reasonable with respect to the Certificateholder, as applicable, or otherwise with respect to the purposes of this Agreement, all such reports or information to be provided at the expense of the Certificateholder, in accordance with such reasonable and explicit instructions and directions as the Certificateholder may provide.

Section 4.7

Advances.

If the Monthly Payment on a Loan or a portion thereof is delinquent as of its Due Date, other than as a result of interest shortfalls due to bankruptcy proceedings or application of the Relief Act, and the related Servicer fails to make an advance of the delinquent amount pursuant to the related Servicing Agreement, the Master Servicer shall deposit in the Distribution Account, from its own funds or from amounts on deposit in the Distribution Account that are held for future distribution, not later than the Distribution Account Deposit Date immediately preceding the related Distribution Date an amount equal to such delinquency, net of the Servicing Fee and Master Servicing Fee for such Loan except to the extent the Master Servicer determines any such advance to be nonrecoverable from Liquidation Proceeds, Insurance

Proceeds, or future payments on the Loan for which such Advance was made. Any amounts held for future distribution and so used shall be appropriately reflected in the Master Servicer’s records and replaced by the Master Servicer by deposit in the Distribution Account on or before any future Distribution Account Deposit Date to the extent that related Available Distribution Amount (determined without regard to Advances to be made on the related Distribution Account Deposit Date) shall be less than the total amount that would be distributed to the related Classes of Certificateholders pursuant to Section 4.1 on such Distribution Date if such amounts held for future distributions had not been so used to make Advances. Subject to the foregoing, the Master Servicer shall continue to make such Advances through the date that the related Servicer is required to do so under its Servicing Agreement. In the event the Master Servicer elects not to make an Advance because the Master Servicer deems such Advance nonrecoverable pursuant to this Section 4.7 on the related Distribution Account Deposit Date, the Master Servicer shall present an Officer’s Certificate to the Trustee (i) stating that the Master Servicer elects not to make an Advance in a stated amount and (ii) detailing the reason it deems the advance to be nonrecoverable.

ARTICLE V

THE CERTIFICATES

Section 5.1

The Certificates.

(a) The Certificates in the aggregate will represent the entire beneficial ownership interest in the Loans and all other assets included in REMIC I.

The Certificates will be substantially in the forms annexed hereto as Exhibits A-1 through A-7. The Certificates of each Class will be issuable in registered form only, in denominations of authorized Percentage Interests as described in the definition thereof. Each Certificate will share ratably in all rights of the related Class.

Upon original issue, the Certificates shall be executed and authenticated by the Securities Administrator and delivered by the Trustee to and upon the written order of the Depositor. The Certificates shall be executed by manual or facsimile signature on behalf of the Trust by the Securities Administrator by an authorized signatory. Certificates bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Securities Administrator shall bind the Trust, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Certificates or did not hold such offices at the date of such Certificates. No Certificate shall be entitled to any benefit under this Agreement or be valid for any purpose, unless there appears on such Certificate a certificate of authentication substantially in the form provided herein executed by the Securities Administrator by manual signature, and such certificate of authentication 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.

(b) The Certificates, other than the Class R Certificates, Class P Certificates and Junior Subordinate Certificates, shall initially be issued as one or more Certificates held by the Book-Entry Custodian or, if appointed to hold such Certificates as provided below, the Depository and registered in the name of the Depository or its nominee and, except as provided below, registration of such Certificates may not be transferred by the Securities Administrator except to another Depository that agrees to hold such Certificates for the respective Certificate Owners with Ownership Interests therein. The Certificate Owners shall hold their respective Ownership Interests in and to such Certificates through the book-entry facilities of the Depository and, except as provided below, shall not be entitled to definitive, fully registered Certificates (“Definitive Certificates”) in respect of such Ownership Interests. All transfers by Certificate Owners of their respective Ownership Interests in the Book-Entry Certificates shall be made in accordance with the procedures established by the Depository Participant or brokerage firm representing such Certificate Owner. Each Depository Participant shall only transfer the Ownership Interests in the Book-Entry Certificates of Certificate Owners it represents or of brokerage firms for which it acts as agent in accordance with the Depository’s normal procedures. The Securities Administrator is hereby initially appointed as the Book-Entry Custodian and hereby agrees to act as such in accordance herewith and in accordance with the agreement that it has with the Depository authorizing it to act as such. The Book-Entry Custodian may, and, if it is no longer qualified to act as such, the Book-Entry Custodian shall, appoint, by a written instrument delivered to the Depositor, the Servicers, the Master Servicer

and, if the Trustee is not the Book-Entry Custodian, the Trustee, any other transfer agent (including the Depository or any successor Depository) to act as Book-Entry Custodian under such conditions as the predecessor Book-Entry Custodian and the Depository or any successor Depository may prescribe, provided that the predecessor Book-Entry Custodian shall not be relieved of any of its duties or responsibilities by reason of any such appointment of other than the Depository. If the Securities Administrator resigns or is removed in accordance with the terms hereof, the successor Securities Administrator or, if it so elects, the Depository shall immediately succeed to its predecessor’s duties as Book-Entry Custodian. The Depositor shall have the right to inspect, and to obtain copies of, any Certificates held as Book-Entry Certificates by the Book-Entry Custodian.

(c) Any Junior Subordinate Certificate initially offered and sold in offshore transactions in reliance on Regulation S shall be issued in the form of a temporary global certificate in definitive, fully registered form (each, a “Regulation S Temporary Global Certificate”), which shall be deposited with the Securities Administrator or an agent of the Securities Administrator as custodian for the Depository and registered in the name of Cede & Co. as nominee of the Depository for the account of designated agents holding on behalf of Euroclear or Clearstream. Beneficial interests in each Regulation S Temporary Global Certificate may be held only through Euroclear or Clearstream; provided, however, that such interests may be exchanged for interests in a Definitive Certificate in accordance with the requirements described in Section 5.2. After the expiration of the Release Date, a beneficial interest in a Regulation S Temporary Global Certificate may be exchanged for a beneficial interest in the related permanent global certificate of the same Class (each, a “Regulation S Permanent Global Certificate”), in accordance with the procedures set forth in Section 5.2. Each Regulation S Permanent Global Certificate shall be deposited with the Securities Administrator or an agent of the Securities Administrator as custodian for the Depository and registered in the name of Cede & Co. as nominee of the Depository.

(d) The Junior Subordinate Certificates and Class P Certificates offered and sold to Qualified Institutional Buyers (“QIBs”) in reliance on Rule 144A under the Securities Act (“Rule 144A”) will be issued in the form of Definitive Certificates.

(e) The Trustee, the Servicers, the Securities Administrator, the Master Servicer and the Depositor may for all purposes (including the making of payments due on the Book-Entry Certificates and Global Certificates) deal with the Depository as the authorized representative of the Certificate Owners with respect to the Book-Entry Certificates and Global Certificates for the purposes of exercising the rights of Certificateholders hereunder. The rights of Certificate Owners with respect to the Book-Entry Certificates and Global Certificates shall be limited to those established by law and agreements between such Certificate Owners and the Depository Participants and brokerage firms representing such Certificate Owners. Multiple requests and directions from, and votes of, the Depository as Holder of the Book-Entry Certificates and Global Certificates with respect to any particular matter shall not be deemed inconsistent if they are made with respect to different Certificate Owners. The Securities Administrator may establish a reasonable record date in connection with solicitations of consents from or voting by Certificateholders and shall give notice to the Depository of such record date.

If (i)(A) the Depositor advises the Securities Administrator in writing that the Depository is no longer willing or able to properly discharge its responsibilities as Depository, and (B) the Depositor is unable to locate a qualified successor, (ii) the Depositor at its option advises the Securities Administrator in writing that it elects to terminate the book-entry system through the Depository or (iii) after the occurrence of a Master Servicer Event of Default, Certificate Owners representing in the aggregate not less than 51% of the Ownership Interests of the Book-Entry Certificates advise the Securities Administrator through the Depository, in writing, that the continuation of a book-entry system through the Depository is no longer in the best interests of the Certificate Owners, the Securities Administrator shall notify all Certificate Owners, through the Depository, of the occurrence of any such event and of the availability of Definitive Certificates to Certificate Owners requesting the same. With respect to a Global Certificate, the related Certificate Owner (other than a Holder of a Regulation S Temporary Global Certificate) may request that its interest in a Global Certificate be exchanged for a Definitive Certificate. Upon surrender to the Securities Administrator of the Book-Entry Certificates by the Book-Entry Custodian or the Depository, as applicable, or the Global Certificates by the Depository accompanied by registration instructions from the Depository for registration of transfer, the Securities Administrator shall cause the Definitive Certificates to be issued. Such Definitive Certificates will be issued in minimum denominations of $10,000 except that any beneficial ownership that was represented by a Book-Entry Certificate, or a Global Certificate, as applicable in an amount less than $10,000 immediately prior to the issuance of a Definitive Certificate shall be issued in a minimum denomination equal to the amount represented by such Book-Entry Certificate or a Global Certificate, as applicable. None of the Depositor, the Servicers, the Master Servicer, the Securities Administrator or the Trustee shall be liable for any delay in the delivery of such instructions and may conclusively rely on, and shall be protected in relying on, such instructions. Upon the issuance of Definitive Certificates all references herein to obligations imposed upon or to be performed by the Depository shall be deemed to be imposed upon and performed by the Securities Administrator on behalf of the Trustee, to the extent applicable with respect to such Definitive Certificates, and the Securities Administrator on behalf of the Trustee shall recognize the Holders of the Definitive Certificates as Certificateholders hereunder.

(f) Neither the Trustee nor the Securities Administrator shall have any liability to the Trust Fund and shall be indemnified by the Trust Fund for, any cost, liability or expense incurred by them arising from a registration of a Certificate or transfer, pledge sale or other disposition of a Certificate in reliance upon a certification, Officer’s Certificate, affidavit, ruling or Opinion of Counsel described in this Article V.

Section 5.2

Registration of Transfer and Exchange of Certificates.

(a) The Securities Administrator shall cause to be kept at one of the offices or agencies to be appointed by the Securities Administrator in accordance with the provisions of Section 8.11, a Certificate Register for the Certificates in which, subject to such reasonable regulations as it may prescribe, the Securities Administrator shall provide for the registration of Certificates and of transfers and exchanges of Certificates as herein provided.

(b) No transfer of any Junior Subordinate Certificate or Class P Certificate shall be made unless that transfer is made pursuant to an effective registration statement under

the Securities Act, and effective registration or qualification under applicable state securities laws, or is made in a transaction that does not require such registration or qualification. In the event that such a transfer of a Junior Subordinate Certificate or Class P Certificate is to be made without registration or qualification (other than in connection with the initial transfer of any such Certificate by the Depositor), the Securities Administrator shall require receipt of: (i) if such transfer is purportedly being made in reliance upon Rule 144A under the Securities Act, written certifications from the Certificateholder desiring to effect the transfer and from such Certificateholder’s prospective transferee, substantially in the form attached hereto as Exhibit B-1; (ii) if such transfer is purportedly being made in reliance upon Rule 501(a) under the Securities Act, written certifications from the Certificateholder desiring to effect the transfer and from such Certificateholder’s prospective transferee, substantially in the form attached hereto as Exhibit B-2; (iii) if such transfer is purportedly being made in reliance on Regulation S, a written certification from the prospective transferee, substantially in the form attached hereto as Exhibit B-3 and (iv) in all other cases, an Opinion of Counsel satisfactory to the Securities Administrator that such transfer may be made without such registration or qualification (which Opinion of Counsel shall not be an expense of the Trust Fund or of the Depositor, the Trustee, the Master Servicer, the Securities Administrator or the Servicers), together with copies of the written certification(s) of the Certificateholder desiring to effect the transfer and/or such Certificateholder’s prospective transferee upon which such Opinion of Counsel is based, if any. Neither of the Depositor nor the Securities Administrator is obligated to register or qualify any such 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 any such Certificate shall, and does hereby agree to, indemnify the Trustee, the Depositor, the Master Servicer, the Securities Administrator and the Servicers 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.

A holder of a beneficial interest in a Regulation S Temporary Global Certificate must provide Euroclear or Clearstream, as the case may be, with a certificate in the form of Annex A to Exhibit B-4 hereto certifying that the beneficial owner of the interest in such Global Certificate is not a U.S. Person (as defined in Regulation S), and Euroclear or Clearstream, as the case may be, must provide to the Trustee and Securities Administrator a certificate in the form of Exhibit B-4 hereto prior to (i) the payment of interest or principal with respect to such holder’s beneficial interest in the Regulation S Temporary Global Certificate and (ii) any exchange of such beneficial interest for a beneficial interest in a Regulation S Permanent Global Certificate.

(c) No transfer of a Class P Certificate or a Residual Certificate or any interest therein shall be made to any Plan subject to ERISA or Section 4975 of the Code, any Person acting, directly or indirectly, on behalf of any such Plan or any Person acquiring such Certificates with “Plan Assets” of a Plan within the meaning of the Department of Labor regulation promulgated at 29 C.F.R. § 2510.3-101 (“Plan Assets”) unless the Securities Administrator is provided with an Opinion of Counsel on which the Depositor, the Master Servicer, the Securities Administrator, the Trustee and the Servicers may rely, which establishes to the satisfaction of the Securities Administrator that the purchase of such Certificates is permissible under applicable law, will not constitute or result in any prohibited transaction under ERISA or Section 4975 of the Code and will not subject the Depositor, the Servicers, the Trustee, the Master Servicer, the Securities Administrator or the Trust Fund to any obligation or

liability (including obligations or liabilities under ERISA or Section 4975 of the Code) in addition to those undertaken in this Agreement, which Opinion of Counsel shall not be an expense of the Depositor, the Servicers, the Trustee, the Master Servicer, the Securities Administrator, the Trust Fund. An Opinion of Counsel will not be required in connection with the initial transfer of any such Certificate by the Depositor to an affiliate of the Depositor (in which case, the Depositor or any affiliate thereof shall have deemed to have represented that such affiliate is not a Plan or a Person investing Plan Assets) and the Securities Administrator shall be entitled to conclusively rely upon a representation (which, upon the request of the Securities Administrator, shall be a written representation) from the Depositor of the status of such transferee as an affiliate of the Depositor.

Each Transferee of a Class M Certificate or Class B Certificate will be deemed to have represented by virtue of its purchase or holding of such Certificate (or interest therein) that either (a) such Transferee is not a Plan or purchasing such Certificate with Plan Assets, (b) for Certificates other than Class B-3, Class B-4 or Class B-5 Certificates, it has acquired and is holding such Certificate in reliance on Prohibited Transaction Exemption (“PTE”) 94-84 or FAN 97-03E, as amended by PTE 97-34, 62 Fed. Reg. 39021 (July 21, 1997), PTE 2000-58, 65 Fed. Reg. 67765 (November 13, 2000) and PTE 2002-41, 67 Fed. Reg. 54487 (August 22, 2002) (the “Exemption”), and that it understands that there are certain conditions to the availability of the Exemption including that such Certificate must be rated, at the time of purchase, not lower than “BBB-” (or its equivalent) by a Rating Agency or (c) the following conditions are satisfied: (i) such Transferee is an insurance company, (ii) the source of funds used to purchase or hold such Certificate (or interest therein) is an “insurance company general account” (as defined in PTCE 95-60, and (iii) the conditions set forth in Sections I and III of PTCE 95-60 have been satisfied.

If any Certificate or any interest therein is acquired or held in violation of the conditions described in this Section 5.2(c), the next preceding permitted beneficial owner will be treated as the beneficial owner of that Certificate, retroactive to the date of transfer to the purported beneficial owner. Any purported beneficial owner whose acquisition or holding of any certificate or interest therein was effected in violation of the conditions described in this Section 5.2(c) shall indemnify and hold harmless the Depositor, the Trustee, the Servicers, the Master Servicer, the Securities Administrator and the Trust Fund from and against any and all liabilities, claims, costs or expenses incurred by those parties as a result of that acquisition or holding.

(d) Each Transferee of a Class R Certificate shall be deemed by the acceptance or acquisition of the related 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 Transferee of a Class R Certificate are expressly subject to the following provisions:

(i) Each such Transferee shall be a Permitted Transferee and shall promptly notify the Securities Administrator of any change or impending change in its status as a Permitted Transferee.

(ii) No Person shall acquire an Ownership Interest in a Class R Certificate unless such Ownership Interest is a pro rata undivided interest.

(iii) In connection with any proposed transfer of any Ownership Interest in a Class R Certificate, the Securities Administrator shall as a condition to registration of the transfer, require delivery to it, in form and substance satisfactory to it, of each of the following:

(A) an affidavit in the form of Exhibit C hereto from the proposed Transferee to the effect that such Transferee is a Permitted Transferee and that it is not acquiring its Ownership Interest in the Class R Certificate that is the subject of the proposed transfer as a nominee, trustee or agent for any Person who is not a Permitted Transferee; and

(B) a covenant of the proposed Transferee to the effect that the proposed Transferee agrees to be bound by and to abide by the transfer restrictions applicable to the Class R Certificates.

(iv) Any attempted or purported transfer of any Ownership Interest in a Class R 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 a Class R Certificate, then the prior Holder of such Class R Certificate that is a Permitted Transferee shall, upon discovery that the registration of transfer of such Class R 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 Class R Certificate. The Securities Administrator shall be under no liability to any Person for any registration of transfer of a Class R Certificate that is in fact not permitted by this Section or for making any distributions due on such Class R Certificate to the Holder thereof or taking any other action with respect to such Holder under the provisions of this Agreement so long as the Securities Administrator received the documents specified in clause (iii). The Securities Administrator shall be entitled to recover from any Holder of a Class R Certificate that was in fact not a Permitted Transferee at the time such distributions were made all distributions made on such Class R Certificate. Any such distributions so recovered by the Securities Administrator shall be distributed and delivered by the Securities Administrator to the prior Holder of such Class R Certificate that is a Permitted Transferee.

(v) If any Person other than a Permitted Transferee acquires any Ownership Interest in a Class R Certificate in violation of the restrictions in this Section, then the Securities Administrator shall have the right but not the obligation, without notice to the Holder of such Class R Certificate or any other Person having an Ownership Interest therein, to notify the Depositor to arrange for the sale of such Class R 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 Securities Administrator to the previous Holder of such Class R Certificate that is a Permitted Transferee, except that in the event that the Securities

Administrator determines that the Holder of such Class R Certificate may be liable for any amount due under this Section or any other provisions of this Agreement, the Securities Administrator 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 Securities Administrator and it shall not be liable to any Person having an Ownership Interest in a Class R 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 Class R Certificate in violation of the restrictions in this Section, then the Securities Administrator 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 Class R 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 Securities Administrator, in form and substance satisfactory to the Securities Administrator, (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 rating of the Certificates and (ii) an Opinion of Counsel to the effect that such removal will not cause any REMIC created hereunder to fail to qualify as a REMIC. The Holder of the Class R Certificate issued hereunder, while not a Disqualified Organization, is the Tax Matters Person.

(e) Subject to the preceding subsections, upon surrender for registration of transfer of any Certificate at any office or agency of the Securities Administrator maintained for such purpose pursuant to Section 8.11, the Securities Administrator shall execute, authenticate and deliver, in the name of the designated Transferee or Transferees, one or more new Certificates of the same Class of a like aggregate Percentage Interest.

(f) At the option of the Holder thereof, any Certificate may be exchanged for other Certificates of the same Class with Authorized Denominations and a like aggregate Percentage Interest, upon surrender of such Certificate to be exchanged at any office or agency of the Securities Administrator maintained for such purpose pursuant to Section 8.11. Whenever any Certificates are so surrendered for exchange, the Securities Administrator shall execute, authenticate and deliver, the Certificates which the Certificateholder making the exchange is entitled to receive. Every Certificate presented or surrendered for transfer or exchange shall (if so required by the Securities Administrator) be duly endorsed by, or be accompanied by a written instrument of transfer in the form satisfactory to the Securities Administrator duly executed by, the Holder thereof or his attorney duly authorized in writing.

(g) No service charge to the Certificateholders shall be made for any transfer or exchange of Certificates, but the Securities Administrator 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.

(h) All Certificates surrendered for transfer and exchange shall be canceled and destroyed by the Securities Administrator in accordance with its customary procedures.

Section 5.3

Mutilated, Destroyed, Lost or Stolen Certificates.

If (i) any mutilated Certificate is surrendered to the Securities Administrator, or the Securities Administrator receives evidence to its satisfaction of the destruction, loss or theft of any Certificate and of the ownership thereof, and (ii) there is delivered to Securities Administrator such security or indemnity as may be required by it to save it harmless, then, in the absence of actual knowledge by the Securities Administrator that such Certificate has been acquired by a protected purchaser, the Securities Administrator, shall execute, authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new Certificate of the same Class and of like denomination and Percentage Interest. Upon the issuance of any new Certificate under this Section, the Securities Administrator may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Securities Administrator) connected therewith. Any replacement Certificate issued pursuant to this Section shall constitute complete and indefeasible evidence of ownership in the applicable REMIC created hereunder, as if originally issued, whether or not the lost, stolen or destroyed Certificate shall be found at any time.

Section 5.4

Persons Deemed Owners.

The Depositor, the Servicers, the Trustee, the Master Servicer, the Securities Administrator and any agent of any of them may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions pursuant to Section 4.1 and for all other purposes whatsoever, and none of the Depositor, the Servicers, the Trustee, the Master Servicer, the Securities Administrator or any agent of any of them shall be affected by notice to the contrary.

Section 5.5

Certain Available Information.

On or prior to the date of the first sale of any Junior Subordinate Certificate or Class P Certificate to an Independent third party, the Depositor shall provide to the Securities Administrator ten copies of any private placement memorandum or other disclosure document used by the Depositor in connection with the offer and sale of such Certificate. In addition, if any such private placement memorandum or disclosure document is revised, amended or supplemented at any time following the delivery thereof to the Securities Administrator, the Depositor promptly shall inform the Securities Administrator of such event and shall deliver to the Securities Administrator ten copies of the private placement memorandum or disclosure document, as revised, amended or supplemented. The Securities Administrator shall maintain at its office as set forth in Section 11.5 hereof and shall make available free of charge during normal business hours for review by any Holder of a Certificate or any Person identified to the Securities Administrator as a prospective transferee of a Certificate, originals or copies of the following items: (i) in the case of a Holder or prospective transferee of a Junior Subordinate Certificate or Class P Certificate, the private placement memorandum or other disclosure document relating to such Class of Certificates, in the form most recently provided to the

Securities Administrator; and (ii) in all cases, (A) this Agreement and any amendments hereof entered into pursuant to Section 11.1, (B) all monthly statements required to be delivered to Certificateholders of the Junior Subordinate Certificates pursuant to Section 4.6 since the Closing Date, and all other notices, reports, statements and written communications delivered to the Certificateholders of the relevant Class pursuant to this Agreement since the Closing Date and (C) any copies of all Officers’ Certificates of the Servicers since the Closing Date delivered to the Master Servicer to evidence such Person’s determination that any Monthly Advance or Servicing Advance was, or if made, would be a Nonrecoverable Monthly Advance or Nonrecoverable Servicing Advance. Copies and mailing of any and all of the foregoing items will be available from the Securities Administrator upon request at the expense of the Person requesting the same.

As compensation therefor, the Trustee shall be entitled to the Master Servicing Fee and all funds relating to the Loans, investment earnings on the Distribution Account and all other remuneration to which the Master Servicer would have been entitled if it had continued to act hereunder. Notwithstanding the above and subject to the immediately following paragraph, the Trustee may, if it shall be unwilling to so act, or shall, if it is unable to so act or if it is prohibited by law from making advances regarding delinquent mortgage loans or if the Holders of Certificates evidencing, in aggregate, not less than 51% of the Certificate Principal Balance of the Certificates so request in writing promptly appoint or petition a court of competent jurisdiction to appoint, an established mortgage loan servicing institution acceptable to each Rating Agency and having a net worth of not less than $15,000,000, as the successor to the Master Servicer under this Agreement in the assumption of all or any part of the responsibilities, duties or liabilities of the Master Servicer under this Agreement.

The Depositor, the Trustee and such successor shall take such action, consistent with this Agreement, as shall be necessary to effectuate any such succession. Pending appointment of a successor to the Master Servicer (and, if applicable, the Securities Administrator) under this Agreement, the Trustee shall act in such capacity as hereinabove provided. The transition costs and expenses incurred by the Trustee in connection with t50.he replacement of the Master Servicer (and, if applicable, the Securities Administrator) shall be reimbursed out of the Trust Fund.

(b) Not later than the later of sixty (60) days after the occurrence of any event, which constitutes or which, with notice or lapse of time or both, would constitute a Master

Servicer Event of Default or five (5) days after a Responsible Officer of the Trustee becomes aware of the occurrence of such an event, the Trustee shall transmit by mail to all Holders of Certificates notice of each such occurrence, unless such default or Master Servicer Event of Default shall have been cured or waived.

Section 7.4

Waiver of Master Servicer Events of Default.

The Holders evidencing, in aggregate, not less than 66-2/3% of the aggregate Percentage Interests of all Certificates affected by any default or Master Servicer Event of Default hereunder may waive such default or Master Servicer Event of Default; provided, however, a default or Master Servicer Event of Default under clause (vi) of Section 7.1 may be waived only by all of the Holders of the related Regular Interest Certificates.

No such waiver shall extend to any subsequent or other default or Master Servicer Event of Default or impair any right consequent thereon except to the extent expressly so waived.

Section 8.8

Successor Trustee or Securities Administrator.

Any successor trustee or successor securities administrator appointed as provided in Section 8.7 shall execute, acknowledge and deliver to the Depositor and its predecessor trustee or predecessor securities administrator an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee or predecessor securities administrator shall become effective and such successor trustee or successor securities administrator without any further act, deed or conveyance, shall become fully vested with all the rights, powers, duties and obligations of its predecessor hereunder, with the like effect as if originally named as trustee or securities administrator herein. The predecessor trustee or predecessor securities administrator shall deliver to the successor trustee or successor securities administrator all Loan Documents and related documents and statements to the extent held by it hereunder, as well as all moneys, held by it hereunder, and the Depositor and the predecessor trustee or predecessor securities administrator shall execute and deliver such instruments and do such other things as may reasonably be required for more fully and certainly vesting and confirming in the successor trustee or successor securities administrator all such rights, powers, duties and obligations.

No successor trustee or successor securities administrator shall accept appointment as provided in this Section unless at the time of such acceptance such successor trustee or successor securities administrator shall be eligible under the provisions of Section 8.6 and the appointment of such successor trustee or successor securities administrator shall not result in a downgrading of any Class of Certificates by any Rating Agency, as evidenced by a letter from each Rating Agency.

Section 9.1

Termination Upon Purchase or Liquidation of the Loans.

(a) Subject to Section 9.2, the respective obligations and responsibilities under this Agreement of the Depositor, the Master Servicer, the Securities Administrator and the Trustee (other than the obligations of the Master Servicer to the Securities Administrator and the Trustee pursuant to Section 8.5 and of the Master Servicer to pay Compensating Interest to the Securities Administrator and the Securities Administrator to make payments in respect of REMIC I Regular Interests or the Classes of Certificates as hereinafter set forth) shall terminate upon payment to the Certificateholders and the deposit of all amounts held by or on behalf of the Trustee and required hereunder to be so paid or deposited on the Distribution Date coinciding with or following the earlier to occur of (i) the purchase by the Master Servicer (as defined below) of all Loans and each REO Property remaining in REMIC I and (ii) the final payment or other liquidation (or any advance with respect thereto) of the last Loan or REO Property remaining in REMIC I; provided, however, that in no event shall the trust created hereby continue beyond the earlier of (a) the expiration of 21 years from the death of the last survivor of the descendants of Xxxxxx X. Xxxxxxx, the late ambassador of the United States to the Court of St. Xxxxx, living on the date hereof and (b) the Last Scheduled Distribution Date. The purchase by the Master Servicer of all Loans and each REO Property remaining in REMIC I shall be at a price (the “Termination Price”) equal to the sum of (i) the greater of (A) the aggregate Purchase Price of all the Loans included in REMIC I, plus the appraised value of each REO Property, if any, included in REMIC I, such appraisal to be conducted by an appraiser mutually agreed upon by the Master Servicer and the Trustee in their reasonable discretion and (B) the aggregate fair market value of all of the assets of REMIC I (as determined by the Master Servicer and the Trustee, 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 Certificateholders pursuant to the third paragraph of this Section 9.1) plus (ii) any amounts due the Servicers and the Master Servicer in respect of unpaid Servicing Fees, Master Servicing Compensation and outstanding Monthly Advances and Servicing Advances.

(b) The Master Servicer shall have the right to purchase all of the Loans and each REO Property remaining in REMIC I pursuant to clause (i) of the preceding paragraph no later than the Determination Date in the month immediately preceding the Distribution Date on which the Certificates will be retired; provided, however, that the Master Servicer may elect to purchase all of the Loans and each REO Property remaining in REMIC I pursuant to clause (i) above only if the aggregate Scheduled Principal Balance of the Loans and the fair market value of each REO Property remaining in the Trust Fund at the time of such election is less than or equal to 5% of the aggregate Scheduled Principal Balance of the Loans as of the Cut-Off Date plus the Original Pre-Funded Amount.

(c) Notice of the liquidation of the Certificates shall be given promptly by the Securities Administrator by letter to the Certificateholders mailed (a) in the event such notice is given in connection with the purchase of the Loans and each REO Property by the Master Servicer, not earlier than the 15th day and not later than the 25th day of the month next preceding the month of the final distribution on the Certificates or (b) otherwise during the

month of such final distribution on or before the Determination Date in such month, in each case specifying (i) the Distribution Date upon which the Trust Fund will terminate and the final payment in respect of REMIC I Regular Interests or the Certificates will be made upon presentation and surrender of the related Certificates at the office of the Securities Administrator therein designated, (ii) the amount of any such final payment, (iii) that no interest shall accrue in respect of REMIC I Regular Interests or Certificates from and after the Interest Accrual Period relating to the final Distribution Date therefor and (iv) that the Record Date otherwise applicable to such Distribution Date is not applicable, payments being made only upon presentation and surrender of the Certificates at the office of the Securities Administrator. In the event such notice is given in connection with the purchase of all of the Loans and each REO Property remaining in the REMIC I by the Master Servicer, the Master Servicer shall deliver to the Securities Administrator for deposit in the Distribution Account not later than the last Business Day of the month next preceding the month of the final distribution on the Certificates an amount in immediately available funds equal to the above-described Termination Price. The Securities Administrator shall remit (a) to the Master Servicer from such funds deposited in the Distribution Account (i) any amounts which the Master Servicer notifies it in writing that the Master Servicer would be permitted to withdraw and retain from the Distribution Account pursuant to Section 3.24 and (ii) any other amounts otherwise payable by the Securities Administrator to the Master Servicer from amounts on deposit in the Distribution Account pursuant to the terms of this Agreement and notified by the Master Servicer in writing and (b) to the Servicers, any amounts reimbursable to the Servicers pursuant to the Servicing Agreements, in each case prior to making any final distributions pursuant to Section 9.1(d) below. Upon certification to the Trustee and the Securities Administrator by a Servicing Officer of the making of such final deposit, the Trustee shall promptly release to the Master Servicer the Mortgage Files for the remaining Loans, and the Trustee shall execute all assignments, endorsements and other instruments necessary to effectuate such transfer in each case without recourse, representation or warranty.

(d) Upon presentation of the Certificates by the Certificateholders on the final Distribution Date, the Securities Administrator shall distribute to each Certificateholder so presenting and surrendering its Certificates the amount otherwise distributable on such Distribution Date in accordance with Section 4.1 in respect of the Certificates so presented and surrendered. Any funds not distributed to any Holder or Holders of Certificates being retired on such Distribution Date because of the failure of such Holder or Holders to tender their Certificates shall, on such date, be set aside and held in trust and credited to the account of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to this Section 9.1 shall not have been surrendered for cancellation within six months after the time specified in such notice, the Securities Administrator shall mail a second notice to the remaining non-tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Securities Administrator shall, directly or through an agent, mail a final notice to the remaining non-tendering Certificateholders concerning surrender of their Certificates. The costs and expenses of maintaining the funds in trust and of contacting such Certificateholders shall be paid out of the assets remaining in the trust funds. If within one year after the final notice any such Certificates shall not have been surrendered for cancellation, the Securities Administrator shall pay to the Depositor all such amounts, and all rights of non-tendering Certificateholders in or to

such amounts shall thereupon cease. No interest shall accrue or be payable to any Certificateholder on any amount held in trust by the Securities Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) for final payment thereof in accordance with this Section 9.1. Any such amounts held in trust by the Securities Administrator shall be held in an Eligible Account and the Securities Administrator may direct any depository institution maintaining such account to invest the funds in one or more Eligible Investments. All income and gain realized from the investment of funds deposited in such accounts held in trust by the Securities Administrator shall be for the benefit of the Securities Administrator; provided, however, that the Securities Administrator shall deposit in such account the amount of any loss of principal incurred in respect of any such Eligible Investment made with funds in such accounts immediately upon the realization of such loss.

Immediately following the deposit of funds in trust hereunder in respect of the Certificates, the Trust Fund shall terminate.

In addition, prior to taking any action with respect to any REMIC or the respective assets of each, or causing any REMIC to take any action, which is not contemplated under the terms of this Agreement, the Securities Administrator shall 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 REMIC, and the Securities Administrator shall not take any such action or cause any REMIC to take any

such action as to which the Trustee has advised it in writing that an Adverse REMIC Event could occur. The Trustee may consult with counsel to make such written advice, and the cost of same shall be borne by the party seeking to take the action not permitted by this Agreement, but in no event shall such cost be an expense of the Trustee.

(g) In the event that any tax is imposed on “prohibited transactions” of any REMIC created hereunder as defined in Section 860F(a)(2) of the Code, on the “net income from foreclosure property” of such REMIC as defined in Section 860G(c) of the Code, on any contributions to any such REMIC after the Startup Day therefor pursuant to Section 860G(d) of the Code, or any other tax is imposed by the Code or any applicable provisions of state or local tax laws, such tax shall be charged (i) to the Trustee pursuant to Section 10.3 hereof, if such tax arises out of or results from a breach by the Trustee of any of its obligations under this Article X, (ii) to the Securities Administrator pursuant to Section 10.3 hereof, if such tax arises out of or results from a breach by the Securities Administrator of any of its obligations under this Article X, (iii) to the Master Servicer pursuant to Section 10.3 hereof, if such tax arises out of or results from a breach by the Master Servicer of any of its obligations under Article III or under this Article X, or (iv) against amounts on deposit in the Distribution Account and shall be paid by withdrawal therefrom.

(h) The Trustee and the Securities Administrator shall, for federal income tax purposes, maintain books and records with respect to each REMIC on a calendar year and on an accrual basis.

(i) Following the Startup Day, the Trustee shall not accept any contributions of assets to any REMIC other than in connection with any Substitute Loan delivered in accordance with Section 2.3 unless it shall have received an Opinion of Counsel addressed to it to the effect that the inclusion of such assets in the Trust Fund will not cause the related REMIC to fail to qualify as a REMIC at any time that any Certificates are outstanding or subject such REMIC to any tax under the REMIC Provisions or other applicable provisions of federal, state and local law or ordinances.

(j) Neither the Trustee nor the Securities Administrator shall knowingly enter into any arrangement by which any REMIC will receive a fee or other compensation for services nor permit any REMIC to receive any income from assets other than “qualified mortgages” as defined in Section 860G(a)(3) of the Code or “permitted investments” as defined in Section 860G(a)(5) of the Code.

(k) The Securities Administrator shall apply for an employer identification number with the Internal Revenue Service via a Form SS-4 or other comparable method for each REMIC.

Section 10.3

Indemnification.

(a) The Trustee agrees to be liable for any taxes and costs incurred by the Trust Fund, the Depositor, the Securities Administrator or the Master Servicer including, without limitation, any reasonable attorneys fees imposed on or incurred by the Trust Fund, the Depositor, the Securities Administrator or the Master Servicer as a result of the Trustee’s failure to perform its covenants set forth in this Article X in accordance with the standard of care of the Trustee set forth in this Agreement.

This Agreement may be amended from time to time by the Depositor, the Master Servicer, the Securities Administrator and the Trustee, without the consent of any of the Certificateholders, (a) to cure any ambiguity, to correct or supplement any provision herein which may be inconsistent with any other provision herein, or to make any other provisions with respect to matters or questions arising under this Agreement, (b) to modify, eliminate or add to any provisions to such extent as shall be necessary to maintain the qualification of the Trust Fund as three REMICs at all times that any Certificates are outstanding, provided, that such action shall not, as evidenced by an Opinion of Counsel addressed and delivered to the Trustee, adversely affect in any material respect the interests of any Certificateholder. No amendment shall be deemed to adversely affect in any material respect the interests of any Certificateholder who shall have consented thereto, and no Opinion of Counsel shall be required to address the effect of any such amendment on any such consenting Certificateholder.

This Agreement may also be amended from time to time by the Depositor, the Master Servicer, the Securities Administrator and the Trustee with the consent of the Holders of Certificates evidencing, in aggregate, not less than 66-2/3% of the Trust Fund for the purpose of adding any provisions 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; provided, however, that no such amendment shall (a) reduce in any manner the amount of, or delay the timing of, payments received on Loans which are required to be distributed in respect of any Certificate without the consent of the Holder of such Certificate; (b) adversely affect in any material respect the interest of the Holders of the Senior Certificates (other than the Class R Certificates) in a manner other than as described in (a) above without the consent of the Holders of such Senior Certificates (other than the Class R Certificates) aggregating not less than 66-2/3% of the aggregate Percentage Interest evidenced by all Senior Certificates (other than the Class R Certificates); (c) adversely affect in any material respect the interest of the Holders of the Subordinate Certificates in a manner other than as described in clause (a) above without the consent of the Holders of Subordinate Certificates aggregating not less than 66-2/3% of the aggregate Percentage Interest evidenced by all Subordinate Certificates; (d) adversely affect in any material respect the interest of the Class R Certificateholder without the consent of the Holder of the Class R Certificates; (e) change in any material respect the rights and obligations of the Master Servicer or successor Master Servicer under this Agreement without the prior written consent of such party; or (f) reduce the aforesaid percentage of the Certificates the Holders of which are required to consent to any such amendments without the consent of the Holders of all Certificates then outstanding; provided, that for the purposes of this Agreement, the Holder of the Class R Certificate shall have no right to vote at all times that any Senior Certificates (other than the Class R Certificates), or Subordinate Certificates are outstanding if such amendment relates to the modification, elimination or addition of any provision necessary to maintain the qualification of the Trust Fund as three REMICs. Without limiting the generality of the foregoing, any amendment to this Agreement required in connection with the compliance with or the clarification of any reporting obligations described in Section 3.18 hereof shall not require the consent of any Certificateholder or any Opinion of Counsel or Rating Agency confirmation.

Notwithstanding any contrary provision of this Agreement, the Trustee shall not consent to any amendment to this Agreement unless it shall have first received an Opinion of Counsel addressed to it to the effect that such amendment will not cause any of REMIC I, REMIC II or REMIC III of the Trust Fund to fail to qualify as a REMIC at any time that any REMIC Regular Interests or Regular Interest Certificates are outstanding.

As soon as practicable after the execution of any such amendment, the Trustee shall furnish written notification of the substance of such amendment to each Certificateholder and Rating Agency.

It shall not be necessary for the consent of the Certificateholders under this Section 11.1 to approve the particular form of any proposed amendment, but 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.

Prior to the execution of any amendment to this Agreement, the Trustee shall be entitled to receive and rely upon an Opinion of Counsel addressed to it stating that the execution of such amendment is authorized or permitted by this Agreement. The Trustee may, but shall not be obligated to, enter into any such amendment which affects the Trustee’s own rights, duties or immunities under this Agreement.

Section 11.2 Recordation of Agreement; Counterparts. To the extent permitted by applicable law, this Agreement (or an abstract hereof, if acceptable by the applicable recording office) 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 properties subject to the Mortgages are situated, and in any other appropriate public recording office or elsewhere, such recordation to be effected by the Depositor at the expense of the Certificateholders, but only after the Depositor has delivered to the Trustee an Opinion of Counsel to the effect that such recordation materially and beneficially affects the interests of the Certificateholders.

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 constitute but one and the same instrument.

Section 11.3 Limitation on Rights of Certificateholders. The death or incapacity of any Certificateholder shall not operate to terminate this Agreement or the Trust Fund, nor entitle such Certificateholder’s legal representatives or heirs to claim an accounting or take any action or proceeding in any court for a partition or winding up of the Trust Fund, nor otherwise affect the rights, obligations and liabilities of the parties hereto or any of them.

Except as otherwise expressly provided herein no Certificateholder, solely by virtue of its status as Certificateholder, shall have any right to vote or in any manner otherwise control the operation and management of the Trust Fund, 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, solely by virtue of its status as Certificateholder, shall have any right by virtue or by availing 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 all of the Holders of Certificates evidencing, in aggregate, not less than 25% of the Trust Fund 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 sixty (60) 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 being understood and intended, and being 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 or by availing 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, or to enforce any right under this Agreement, except in the manner herein provided and for the benefit of all Certificateholders. For the protection and enforcement of the provisions of this Section 11.3, each and every Certificateholder and the Trustee shall be entitled to such relief as can be given either at law or in equity.

Section 11.4 Governing Law. THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK (WITHOUT REGARD TO CONFLICTS OF LAWS PRINCIPLES OTHER THAN 5-1401 OF THE GENERAL OBLIGATIONS LAW), AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

Section 11.8

Article and Section References.

All article and section references used in this Agreement, unless otherwise provided, are to articles and sections in this Agreement.

Section 11.9

Grant of Security Interest.

It is the express intent of the parties hereto that the conveyance of the Loans by the Depositor to the Trustee, on behalf of the Trust Fund and for the benefit of the Certificateholders, be, and be construed as, a sale of the Loans by the Depositor and not a pledge of the Loans to secure a debt or other obligation of the Depositor. However, in the event that, notwithstanding the aforementioned intent of the parties, the Loans are held to be property of the Depositor, then, (a) it is the express intent of the parties that such conveyance be deemed a pledge of the Loans by the Depositor to the Trustee, on behalf of the Trust Fund and for the benefit of the related Certificateholders, to secure a debt or other obligation of the Depositor and (b)(1) this Agreement shall also be deemed to be a security agreement within the meaning of Articles 8 and 9 of the Uniform Commercial Code as in effect from time to time in the State of New York; (2) the conveyance provided for in Section 2.1 hereof shall be deemed to be a grant by the Depositor to the Trustee, on behalf of the Trust Fund and for the benefit of the related Certificateholders, of a security interest in all of the Depositor’s right, title and interest in and to the Loans and all amounts payable to the holders of the Loans in accordance with the terms thereof and all proceeds of the conversion, voluntary or involuntary, of the foregoing into cash, instruments, securities or other property, including without limitation all amounts in the Capitalized Interest Account and amounts, other than investment earnings, from time to time held or invested in the Distribution Account and the Pre-Funding Account, whether in the form of cash, instruments, securities or other property; (3) the obligations secured by such security agreement shall be deemed to be all of the Depositor’s obligations under this Agreement, including the obligation to provide to the Certificateholders the benefits of this Agreement relating to the Loans and the Trust Fund; and (4) notifications to persons holding such property, and acknowledgments, receipts or confirmations from persons holding such property, shall be deemed notifications to, or acknowledgments, receipts or confirmations from, financial intermediaries, bailees or agents (as applicable) of the Trustee for the purpose of perfecting such security interest under applicable law. Accordingly, the Depositor hereby grants to the Trustee, on behalf of the Trust Fund and for the benefit of the Certificateholders, a security interest in the Loans and all other property described in clause (2) of the preceding sentence, for the purpose of securing to the Trustee the performance by the Depositor of the obligations described in clause (3) of the preceding sentence. Notwithstanding the foregoing, the parties hereto intend the conveyance pursuant to Section 2.1 to be a true, absolute and unconditional sale of the Loans and assets constituting the Trust Fund by the Depositor to the Trustee, on behalf of the Trust Fund and for the benefit of the Certificateholders.

MORTGAGE PASS-THROUGH CERTIFICATE

evidencing a fractional undivided interest in the distributions allocable to the Class A-[1][2][3][4][5][6][7] Certificates with respect to a trust fund generally consisting of a pool of conventional one- to four-family fixed-rate mortgage loans (the “Mortgage Loans”) secured by one- to four- family residences, units in planned unit developments and individual condominium units (the “Trust Fund”) sold by DEUTSCHE ALT-A SECURITIES, INC.

THIS CERTIFICATE DOES NOT REPRESENT AN OBLIGATION OF OR INTEREST IN DEUTSCHE ALT-A SECURITIES, INC., THE MASTER SERVICER, THE SECURITIES ADMINISTRATOR, THE TRUSTEE, ANY SERVICER OR ANY OF THEIR RESPECTIVE AFFILIATES. NEITHER THIS CERTIFICATE NOR THE UNDERLYING MORTGAGE LOANS ARE GUARANTEED BY ANY AGENCY OR INSTRUMENTALITY OF THE UNITED STATES.

Fund was created pursuant to the Pooling and Servicing Agreement dated as of the Cut-Off Date specified above (the “Agreement”), among the Depositor, Xxxxx Fargo Bank, N.A., as Master Servicer and securities administrator (the “Securities Administrator”) and HSBC Bank USA, National Association as trustee (the “Trustee”), a summary of certain of the pertinent provisions of which is set forth hereafter. To the extent not defined herein, capitalized terms used herein shall have the meaning ascribed to them in the Agreement. 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 its acceptance hereof assents and by which such Holder is bound.

Pursuant to the terms of the Agreement, distributions will be made on the 25^th day of each month or, if such 25^th day is not a Business Day, the Business Day immediately following such 25^th day (a “Distribution Date”), commencing on the First Distribution Date specified above, to the Person in whose name this Certificate is registered at the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs (the “Record Date”), in an amount equal to the product of the Percentage Interest evidenced by this Certificate and the amount required to be distributed to the Holders of Class A-[1][2][3][4][5][6][7] Certificates on such Distribution Date pursuant to the Agreement.

All distributions to the Holder of this Certificate under the Agreement will be made or caused to be made by the Securities Administrator by wire transfer in immediately available funds to the account of the Person entitled thereto if such Person shall have so notified the Securities Administrator in writing at least five Business Days prior to the Record Date immediately prior to such Distribution Date and is the registered owner of Class A-[1][2][3][4][5][6][7] Certificates or otherwise by check mailed by first class mail to the address of the Person entitled thereto, as such name and address shall appear on the Certificate Register. Notwithstanding the above, the final distribution on this Certificate will be made after due notice by the Securities Administrator of the pendency of such distribution and only upon presentation and surrender of this Certificate at the office or agency appointed by the Securities Administrator for that purpose as provided in the Agreement.

The Pass-Through Rate with respect to the first Distribution Date is equal to [______]% per annum and with respect to any Distribution Date thereafter shall be a rate per annum equal to the lesser of (i) [______]% per annum and (ii) the Net WAC Pass-Through Rate for the related Distribution Date.

This Certificate is one of a duly authorized issue of Certificates designated as Mortgage Pass-Through Certificate of the Series specified on the face hereof (herein called the “Certificates”) and representing a Percentage Interest in the Class of Certificates specified on the face hereof equal to the denomination specified on the face hereof divided by the aggregate Certificate Principal Balance of the Class of Certificates specified on the face hereof. The Certificates, in the aggregate, evidence the entire beneficial ownership in the Trust Fund formed pursuant to the Agreement.

The Certificates are limited in right of payment to certain collections and recoveries respecting the related Mortgage Loans and certain other assets included in the Trust Fund, all as more specifically set forth herein and in the Agreement. As provided in the

Agreement, withdrawals from the Protected Accounts and the Distribution Account may be made from time to time for purposes other than distributions to Certificateholders, such purposes including reimbursement of advances made, or certain expenses incurred, with respect to the Mortgage Loans.

The Agreement permits, with certain exceptions therein provided, the amendment thereof and the modification of the rights and obligations of the Depositor, the Master Servicer, the Trustee, the Securities Administrator and the rights of the Certificateholders under the Agreement at any time by the Depositor, the Master Servicer, the Trustee and the Securities Administrator with the consent of the Holders of Certificates evidencing, in the aggregate, not less than 66-2/3% Percentage Interests of all Certificates. Any such consent by the Holder of this Certificate shall be conclusive and binding on such Holder and upon all future Holders of this Certificate and of any Certificate issued upon the transfer hereof or in exchange herefor or in lieu hereof whether or not notation of such consent is made upon this Certificate. The Agreement also permits the amendment thereof, in certain limited circumstances, without the consent of the Holders of any of the Certificates.

As provided in the Agreement and subject to certain limitations therein set forth, the transfer of this Certificate is registrable in the Certificate Register upon surrender of this Certificate for registration of transfer at the offices or agencies appointed by the Securities Administrator as provided in the Agreement, duly endorsed by, or accompanied by an assignment in the form below or other written instrument of transfer in form satisfactory to the Securities Administrator duly executed by, the Holder hereof or such Holder’s attorney duly authorized in writing, and thereupon one or more new Certificates of the same Class in authorized denominations evidencing the same aggregate Percentage Interest will be issued to the designated transferee or transferees.

No service charge will be made for any such registration of transfer or exchange of Certificates, but the Securities Administrator may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any transfer or exchange of Certificates.

The Depositor, the Master Servicer, the Trustee, the Securities Administrator and any agent of the Depositor, the Master Servicer, the Trustee or the Securities Administrator may treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and none of the Depositor, the Master Servicer, the Trustee or the Securities Administrator nor any such agent shall be affected by notice to the contrary.

(i) the final payment or other liquidation (or any advance with respect thereto) of the last Mortgage Loan remaining in the Trust Fund and (ii) the purchase by the party designated in the Agreement at a price determined as provided in the Agreement of all the Mortgage Loans and all property acquired in respect of such Mortgage Loans. The Agreement permits, but does not require, the party designated in the Agreement to purchase all the Mortgage Loans and all property acquired in respect of any Mortgage Loan at a price determined as provided in the Agreement. The exercise of such right will effect early retirement of the Certificates; however, such right to purchase is subject to the aggregate Scheduled Principal Balance of the Mortgage Loans and the fair market value of each REO Property remaining in the Trust Fund at the time of purchase being less than or equal to 5% of the aggregate Scheduled Principal Balance of the Mortgage Loans as of the Cut-Off Date plus the Original Pre-Funded Amount.

The recitals contained herein shall be taken as statements of the Depositor and neither the Trustee nor the Securities Administrator assumes any responsibility for their correctness.

Unless the certificate of authentication hereon has been executed by the Securities Administrator, by manual signature, this Certificate shall not be entitled to any benefit under the Agreement or be valid for any purpose.

IN WITNESS WHEREOF, the Securities Administrator has caused this Certificate to be duly executed.

To the extent not defined herein, capitalized terms used herein shall have the meaning ascribed to them in the Agreement. 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 its acceptance hereof assents and by which such Holder is bound.

Pursuant to the terms of the Agreement, distributions will be made on the 25^th day of each month or, if such 25^th day is not a Business Day, the Business Day immediately following such 25^th day (a “Distribution Date”), commencing on the First Distribution Date specified above, to the Person in whose name this Certificate is registered at the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs (the “Record Date”), in an amount equal to the product of the Percentage Interest evidenced by this Certificate and the amount required to be distributed to the Holders of Class R Certificates on such Distribution Date pursuant to the Agreement.

All distributions to the Holder of this Certificate under the Agreement will be made or caused to be made by the Securities Administrator by wire transfer in immediately available funds to the account of the Person entitled thereto if such Person shall have so notified the Securities Administrator in writing at least five Business Days prior to the Record Date immediately prior to such Distribution Date and is the registered owner of Class R Certificates, or otherwise by check mailed by first class mail to the address of the Person entitled thereto, as such name and address shall appear on the Certificate Register. Notwithstanding the above, the final distribution on this Certificate will be made after due notice by the Securities Administrator of the pendency of such distribution and only upon presentation and surrender of this Certificate at the office or agency appointed by the Securities Administrator for that purpose as provided in the Agreement.

The Agreement permits, with certain exceptions therein provided, the amendment thereof and the modification of the rights and obligations of the Depositor, the Master Servicer,

The Agreement also permits the amendment thereof, in certain limited circumstances, without the consent of the Holders of any of the Certificates.

Each Holder of this Certificate will be deemed to have agreed to be bound by the restrictions set forth in the Agreement to the effect that (i) each person holding or acquiring any Ownership Interest in this Certificate must be a United States Person and a Permitted Transferee, (ii) the transfer of any Ownership Interest in this Certificate will be conditioned upon the delivery to the Securities Administrator of, among other things, an affidavit to the effect that it is a United States Person and Permitted Transferee, (iii) any attempted or purported transfer of any Ownership Interest in this Certificate in violation of such restrictions will be absolutely null and void and will vest no rights in the purported transferee, and (iv) if any person other than a United States Person and a Permitted Transferee acquires any Ownership Interest in this Certificate in violation of such restrictions, then the Depositor will have the right, in its sole discretion and without notice to the Holder of this Certificate, to sell this Certificate to a purchaser selected by the Depositor, which purchaser may be the Depositor, or any affiliate of the Depositor, on such terms and conditions as the Depositor may choose.

No transfer of this Certificate to a Plan subject to ERISA or Section 4975 of the Code, any Person acting, directly or indirectly, on behalf of any such Plan or any Person using “Plan Assets” to acquire this Certificate shall be made except in accordance with Section 5.2(c) of the Agreement.

Prior to registration of any transfer, sale or other disposition of this Certificate, the proposed transferee shall provide to the Securities Administrator (i) an affidavit to the effect that such transferee is any Person other than a Disqualified Organization or the agent (including a broker, nominee or middleman) of a Disqualified Organization, and (ii) a certificate that acknowledges that (A) the Class R Certificates have been designated as representing the beneficial ownership of the residual interests in each REMIC, (B) it will include in its income a pro rata share of the net income of the Trust Fund and that such income may be an “excess inclusion,” as defined in the Code, that, with certain exceptions, cannot be offset by other losses or benefits from any tax exemption, and (C) it expects to have the financial means to satisfy all of its tax obligations including those relating to holding the Class R Certificates. Notwithstanding the registration in the Certificate Register of any transfer, sale or other disposition of this Certificate to a Disqualified Organization or an agent (including a broker, nominee or middleman) of a Disqualified Organization, such registration shall be deemed to be of no legal force or effect whatsoever and such Person shall not be deemed to be a Certificateholder for any purpose, including, but not limited to, the receipt of distributions in respect of this Certificate.

The Holder of this Certificate, by its acceptance hereof, shall be deemed to have consented to the provisions of Section 5.2(c) of the Agreement and to any amendment of the Agreement deemed necessary by counsel of the Depositor to ensure that the transfer of this Certificate to any Person other than a Permitted Transferee or any other Person will not cause any portion of the Trust Fund to cease to qualify as a REMIC or cause the imposition of a tax upon any REMIC.

Loans and the fair market value of each REO Property remaining in the Trust Fund at the time of purchase being less than or equal to 5% of the aggregate Scheduled Principal Balance of the Mortgage Loans as of the Cut-Off Date plus the Original Pre-Funded Amount.

2. In connection with purchases by the Transferee, the Transferee is a “qualified institutional buyer” as that term is defined in Rule 144A under the Securities Act of 1933 (“Rule 144A”) because (i) the Transferee owned and/or invested on a discretionary basis $________________ in securities (except for the excluded securities referred to below) as of the end of the Transferee’s most recent fiscal year (such amount being calculated in accordance with Rule 144A) and (ii) the Transferee satisfies the criteria in the category marked below.

___

___

The Transferee is an insurance company whose primary and predominant business activity is the writing of insurance or the reinsuring of risks underwritten by insurance companies and which is subject to supervision by the insurance commissioner or a similar official or agency of a State, territory or the District of Columbia.

4. For purposes of determining the aggregate amount of securities owned and/or invested on a discretionary basis by the Transferee, the Transferee used the cost of such securities to the Transferee and did not include any of the securities referred to in the preceding paragraph. Further, in determining such aggregate amount, the Transferee may have included securities owned by subsidiaries of the Transferee, but only if such subsidiaries are consolidated with the Transferee in its financial statements prepared in accordance with generally accepted accounting principles and if the investments of such subsidiaries are managed under the Transferee’s direction. However, such securities were not included if the Transferee is a majority-owned, consolidated subsidiary of another enterprise and the Transferee is not itself a reporting company under the Securities Exchange Act of 1934.

5. The Transferee acknowledges that it is familiar with Rule 144A and understands that the Transferor and other parties related to the Certificates are relying and will continue to rely on the statements made herein because one or more sales to the Transferee may be in reliance on Rule 144A.

party (including any separate account) in reliance on Rule 144A, the Transferee will only purchase for the account of a third party that at the time is a “qualified institutional buyer” within the meaning of Rule 144A. In addition, the Transferee agrees that the Transferee will not purchase securities for a third party unless the Transferee has obtained a current representation letter from such third party or taken other appropriate steps contemplated by Rule 144A to conclude that such third party independently meets the definition of “qualified institutional buyer” set forth in Rule 144A.

7. The Transferee will notify each of the parties to which this certification is made of any changes in the information and conclusions herein. Until such notice is given, the Transferee’s purchase of the Certificates will constitute a reaffirmation of this certification as of the date of such purchase. In addition, if the Transferee is a bank or savings and loan as provided above, the Transferee agrees that it will furnish to such parties updated annual financial statements promptly after they become available.
