PRELIMINARY STATEMENT:

The Depositor intends to sell pass-through certificates to be issued hereunder in multiple classes, which in the aggregate will evidence the entire beneficial ownership interest of the Trust Fund created hereunder. The Trust Fund will consist of a segregated pool of assets comprised of the Mortgage Loans and certain other related assets subject to this Agreement.

REMIC I

As provided herein, the Trustee will elect to treat the segregated pool of assets consisting of the Mortgage Loans and certain other related assets subject to this Agreement (other than the Reserve Fund and, for the avoidance of doubt, the Supplemental Interest Trust and the Swap Agreement) as a REMIC for federal income tax purposes, and such segregated pool of assets will be designated as “REMIC I”. The Class R-I Interest will be the sole class of “residual interests” in REMIC I for purposes of the REMIC Provisions (as defined herein). The following table irrevocably sets forth the designation, the REMIC I Remittance Rate, the initial Uncertificated Balance and, for purposes of satisfying Treasury regulation Section 1.860G-1(a)(4)(iii), the “latest possible maturity date” for each of the REMIC I Regular Interests (as defined herein). None of the REMIC I Regular Interests will be certificated.

(a) Upon discovery or receipt of notice (i) of any materially defective document in a Mortgage File or that a document is missing from a Mortgage File, other than a defective or missing document with respect to the Mortgage Loans listed on Schedule A to the Mortgage Loan Purchase Agreement, or (ii) of a breach by the Seller of any representation, warranty or covenant under the Mortgage Loan Purchase Agreement in respect of any Mortgage Loan that materially and adversely affects the value of such Mortgage Loan or the interest therein of the Certificateholders, which notice shall be provided in accordance with Section 9.02(a)(viii), the Trustee shall promptly notify the Seller and the related Servicer of such defect, missing document or breach and request that the Seller deliver such missing document, cure such defect or breach within sixty (60) days from the date the Seller was notified of such missing document, defect or breach, and if the Seller does not deliver such missing document or cure such defect or breach in all material respects during such period, the Trustee shall enforce the obligations of the Seller under the Mortgage Loan Purchase Agreement to repurchase such Mortgage Loan from REMIC I at the Purchase Price within ninety (90) days after the date on which the Seller was notified of such missing document, defect or breach, if and to the extent that the Seller is obligated to do so under the Mortgage Loan Purchase Agreement. The Purchase Price for the repurchased Mortgage Loan shall be remitted to the related Servicer for deposit in the related Collection Account or the Custodial Account, as applicable, and the Trustee, upon receipt of written certification from the related Servicer of such deposit, shall release or cause the applicable Custodian (upon receipt of a request for release in the form attached to the related Custodial Agreement) to release to the Seller the related Mortgage File 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 furnish to it and as shall be necessary to vest in the Seller any Mortgage Loan released pursuant hereto, and the Trustee shall not have any further responsibility with regard to such Mortgage File. In lieu of repurchasing any such Mortgage Loan as provided above, if so provided in the Mortgage Loan Purchase Agreement, the Seller may cause such Mortgage Loan to be removed from REMIC I (in which case it shall become a Deleted Mortgage Loan) and substitute one or more Qualified Substitute Mortgage Loans in the manner and subject to the limitations set forth in Section 2.03(b) of this Agreement. It is understood and agreed that the obligation of the Seller to cure or to repurchase (or to substitute for) any Mortgage Loan as to which a document is missing, a material defect in a constituent document exists or as to which such a breach has occurred and is continuing shall constitute the sole remedy respecting such omission, defect or breach available to the Trustee and the Certificateholders.

In addition, promptly upon the earlier of discovery by a Servicer or receipt of notice by a Servicer of the breach of the representation or covenant of the Seller set forth in Section 5(xiv) of the Mortgage Loan Purchase Agreement which materially and adversely affects the interests of the Holders of the M-5, Class B-1 or Class CE-1 Certificates in any Prepayment Charge, such Servicer shall promptly notify the Seller and the Trustee of such breach. The Trustee shall enforce the obligations of the Seller under

the Mortgage Loan Purchase Agreement to remedy such breach to the extent and in the manner set forth in the Mortgage Loan Purchase Agreement.

(b) Any substitution of Qualified Substitute Mortgage Loans for Deleted Mortgage Loans made pursuant to Section 2.03(a) of this Agreement must be effected prior to the date which is two years after the Startup Day for REMIC I.

As to any Deleted Mortgage Loan for which the Seller substitutes a Qualified Substitute Mortgage Loan or Loans, such substitution shall be effected by the Seller delivering to the Trustee or the applicable Custodian on behalf of the Trustee, for such Qualified Substitute Mortgage Loan or Loans, the Mortgage Note, the Mortgage, the Assignment to the Trustee, and such other documents and agreements, with all necessary endorsements thereon, as are required by Section 2 of the Custodial Agreements, as applicable, together with an Officers’ Certificate providing that each such Qualified Substitute Mortgage Loan satisfies the definition thereof and specifying the Substitution Shortfall Amount (as described below), if any, in connection with such substitution. The applicable Custodian on behalf of the Trustee shall acknowledge receipt of such Qualified Substitute Mortgage Loan or Loans and, within ten (10) Business Days thereafter, review such documents and deliver to the Depositor, the Trustee and the related Servicer, with respect to such Qualified Substitute Mortgage Loan or Loans, an initial certification pursuant to the related Custodial Agreement, with any applicable exceptions noted thereon. Within one year of the date of substitution, the applicable Custodian on behalf of the Trustee shall deliver to the Depositor, the Trustee and the related Servicer a final certification pursuant to the related Custodial Agreement with respect to such Qualified Substitute Mortgage Loan or Loans, with any applicable exceptions noted thereon. Monthly Payments due with respect to Qualified Substitute Mortgage Loans in the month of substitution are not part of REMIC I and will be retained by the Seller. For the month of substitution, distributions to Certificateholders will reflect the Monthly Payment due on such Deleted Mortgage 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 Mortgage Loan. The Depositor shall give or cause to be given written notice to the Certificateholders that such substitution has taken place, shall amend the Mortgage Loan Schedule to reflect the removal of such Deleted Mortgage Loan from the terms of this Agreement and the substitution of the Qualified Substitute Mortgage Loan or Loans and shall deliver a copy of such amended Mortgage Loan Schedule to the Trustee and the related Servicer. Upon such substitution, such Qualified Substitute Mortgage Loan or Loans shall constitute part of the Trust Fund and shall be subject in all respects to the terms of this Agreement and 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 Qualified Substitute Mortgage Loans for one or more Deleted Mortgage Loans, the related Servicer will determine the amount (the “Substitution Shortfall Amount”), if any, by which the aggregate Purchase Price of all such Deleted Mortgage Loans exceeds the aggregate of, as to each such Qualified Substitute Mortgage Loan, the Scheduled Principal Balance thereof as of the date of substitution, together with one month’s interest on such

Scheduled Principal Balance at the applicable Net Mortgage Rate, plus all outstanding P&I Advances and Servicing Advances (including Nonrecoverable P&I Advances and Nonrecoverable Servicing Advances) related thereto. On the date of such substitution, the Seller will deliver or cause to be delivered to the related Servicer for deposit in the related Collection Account or the Custodial Account an amount equal to the Substitution Shortfall Amount, if any, and the Trustee or the applicable Custodian on behalf of the Trustee, upon receipt of the related Qualified Substitute Mortgage Loan or Loans, upon receipt of a request for release in the form attached to the related Custodial Agreement and certification by the related Servicer of such deposit, 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 Mortgage Loan released pursuant hereto.

In addition, the Seller shall obtain at its own expense and deliver to the Trustee an Opinion of Counsel to the effect that such substitution will not cause (a) any federal tax to be imposed on any Trust 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 Trust REMIC to fail to qualify as a REMIC at any time that any Certificate is outstanding.

(c) Upon discovery by the Depositor, the Seller, a Servicer or the Trustee that any Mortgage Loan does not constitute a “qualified mortgage” within the meaning of Section 860G(a)(3) of the Code, the party discovering such fact shall within two (2) Business Days give written notice thereof to the other parties. In connection therewith, the Seller shall repurchase or substitute one or more Qualified Substitute Mortgage Loans for the affected Mortgage Loan within ninety (90) days of the earlier of discovery or receipt of such notice with respect to such affected Mortgage Loan. Such repurchase or substitution shall be made by (i) the Seller if the affected Mortgage 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 Mortgage Loan’s status as a non-qualified mortgage does not result from a breach of a representation or warranty. Any such repurchase or substitution shall be made in the same manner as set forth in Section 2.03(a) of this Agreement. The Trustee shall reconvey to the Seller the Mortgage Loan to be released pursuant hereto in the same manner, and on the same terms and conditions, as it would a Mortgage Loan repurchased for breach of a representation or warranty.

(d) With respect to a breach of the representations made pursuant to Section 5(xiv) of the Mortgage Loan Purchase Agreement that materially and adversely affects the value of such Mortgage Loan or the interest therein of the Certificateholders, the Seller shall be required to take the actions set forth in this Section 2.03 of this Agreement.

(e) Within ninety (90) days of the earlier of discovery by Ocwen or Xxxxx Fargo or receipt of notice by Ocwen or Xxxxx Fargo of the breach of any

representation, warranty or covenant of Ocwen or Xxxxx Fargo, as applicable, set forth in Section 2.05 of this Agreement, which materially and adversely affects the interests of the Certificateholders in any Mortgage Loan or Prepayment Charge, Ocwen or Xxxxx Fargo, as applicable, shall cure such breach in all material respects.

ARTICLE III

ADMINISTRATION AND SERVICING OF THE OCWEN MORTGAGE LOANS

AND XXXXX FARGO MORTGAGE LOANS; ACCOUNTS

SECTION 3.01

Ocwen and Xxxxx Fargo to Act as a Servicer.

The obligations of each of Ocwen and Xxxxx Fargo hereunder to service and administer the Mortgage Loans shall be limited to the Ocwen Mortgage Loans and the Xxxxx Fargo Mortgage Loans, respectively, and with respect to the duties and obligations of each Servicer references herein to the related Mortgage Loans shall be limited to the Ocwen Mortgage Loans (and the related proceeds thereof and related REO Properties) in the case of Ocwen, and the Xxxxx Fargo Mortgage Loans (and the related proceeds thereof and related REO Properties) in the case of Xxxxx Fargo, and in no event shall either Servicer have any responsibility or liability with respect to any Mortgage Loans serviced by the other Servicer hereunder. In addition, from and after the Closing Date, the WAMU Mortgage Loans will be serviced and administered by WAMU pursuant to the Servicing Agreement, and neither Ocwen nor Xxxxx Fargo will have any responsibility to service or administer such Mortgage Loans or have any other obligation with respect to such Mortgage Loans (including reporting or remitting funds to the Master Servicer). Except as otherwise expressly stated herein, references in this Article III to “Servicer” shall refer to Ocwen or Xxxxx Fargo, as the case may be, and any successor thereto as a Servicer.

From and after the Closing Date with respect to the Ocwen Mortgage Loans and the Xxxxx Fargo Mortgage Loans, Ocwen and Xxxxx Fargo shall service and administer the related Mortgage Loans on behalf of the Trust Fund and in the best interests of and for the benefit of the Certificateholders (as determined by the related Servicer in its reasonable judgment) in accordance with the terms of this Agreement and the respective Mortgage Loans and all applicable law and regulations and, to the extent consistent with such terms, in the same manner in which it services and administers similar mortgage loans for its own portfolio, giving due consideration to customary and usual standards of practice of prudent mortgage lenders and loan servicers administering similar mortgage loans but without regard to:

(i) any relationship that the related Servicer or any Affiliate of the related Servicer may have with the related Mortgagor;

(ii) the ownership of any Certificate by the related Servicer or any Affiliate of the related Servicer;

(iii) the related Servicer’s obligation to make P&I Advances or Servicing Advances; or

(iv) the related Servicer’s right to receive compensation for its services hereunder.

To the extent consistent with the foregoing, the related Servicer shall also seek to maximize the timely and complete recovery of principal and interest on the Mortgage Notes with respect to the related Mortgage Loans and shall waive (or permit a Sub-Servicer to waive) a Prepayment Charge only under the following circumstances: (i) such waiver is standard and customary in servicing similar Mortgage Loans and such waiver is related to a default or reasonably foreseeable default and would, in the reasonable judgment of the related Servicer, maximize recovery of total proceeds taking into account the value of such Prepayment Charge and the related Mortgage Loan and, if such waiver is made in connection with a refinancing of the related Mortgage Loan, such refinancing is related to a default or a reasonably foreseeable default, (ii) such Prepayment Charge is unenforceable in accordance with applicable law or the collection of such related Prepayment Charge would otherwise violate applicable law or (iii) the collection of such Prepayment Charge would be considered “predatory” pursuant to written guidance published or issued by any applicable federal, state or local regulatory authority acting in its official capacity and having jurisdiction over such matters. Notwithstanding any provision in this Agreement to the contrary, in the event the Prepayment Charge payable under the terms of the Mortgage Note is less than the amount of the Prepayment Charge set forth in the Prepayment Charge Schedule or other information provided to the related Servicer, the related Servicer shall not have any liability or obligation with respect to such difference, and in addition shall not have any liability or obligation to pay the amount of any uncollected Prepayment Charge if the failure to collect such amount is the direct result of inaccurate or incomplete information on the Prepayment Charge Schedule.

Subject only to the above-described servicing standards (the “Accepted Servicing Practices”) and the terms of this Agreement and of the respective Mortgage Loans, the related Servicer shall have full power and authority, to do or cause to be done any and all things in connection with such servicing and administration which it may deem necessary or desirable with the goal of maximizing proceeds of the Mortgage Loan. Without limiting the generality of the foregoing, the related Servicer in its own name is hereby authorized and empowered by the Trustee when the related Servicer believes it appropriate in its best judgment, to execute and deliver, on behalf of the Trust Fund, the Certificateholders and the Trustee or any of them, and upon written notice to the Trustee, any and all instruments of satisfaction or cancellation, or of partial or full release or discharge or subordination, and all other comparable instruments, with respect to the Mortgage Loans and the Mortgaged Properties and to institute foreclosure proceedings or obtain a deed-in-lieu of foreclosure so as to convert the ownership of such properties, and to hold or cause to be held title to such properties, on behalf of the Trustee, for the benefit of the Trust Fund and the Certificateholders. The related Servicer shall service and administer the Mortgage Loans in accordance with applicable state and federal law and shall provide to the Mortgagors any reports required to be provided to them thereby. The related Servicer shall also comply in the performance of this Agreement with all reasonable rules and requirements of each insurer under any standard hazard insurance policy. Subject to Section 3.14 of this Agreement, the Trustee shall execute, at the written request of a Servicer, and furnish to the related Servicer a power of attorney in the form of Exhibit D hereto and other documents necessary or appropriate to enable the related Servicer to carry out its servicing and administrative duties hereunder or under the

Servicing Agreement, as applicable, and furnished to the Trustee by the related Servicer, and the Trustee shall not be liable for the actions of the related Servicer under such powers of attorney and shall be indemnified by the related Servicer for any cost, liability or expense incurred by the Trustee in connection with the related Servicer’s use or misuse of any such power of attorney.

In accordance with Accepted Servicing Practices, the related Servicer shall make or cause to be made Servicing Advances as necessary for the purpose of effecting the payment of taxes and assessments on the Mortgaged Properties, which Servicing Advances shall be reimbursable in the first instance from related collections from the related Mortgagors pursuant to Section 3.07 of this Agreement, and further as provided in Section 3.09 of this Agreement; provided, however, the related Servicer shall only make such Servicing Advance if the related Mortgagor has not made such payment and if the failure to make such Servicing Advance would result in the loss of the related Mortgaged Property due to a tax sale or foreclosure as result of a tax lien. Any cost incurred by the related Servicer in effecting the payment of taxes and assessments on a Mortgaged Property shall not, for the purpose of calculating the Scheduled Principal Balance of such Mortgage Loan or distributions to Certificateholders, be added to the unpaid principal balance of the related Mortgage Loan, notwithstanding that the terms of such Mortgage Loan so permit.

The parties to this Agreement acknowledge that Servicing Advances shall be reimbursable pursuant to Section 3.09 of this Agreement, and agree that no Servicing Advance shall be rejected or disallowed by any party unless it has been shown that such Servicing Advance was not made in accordance with the terms of this Agreement. Notwithstanding the foregoing, the parties hereto understand and agree that, with respect to any Mortgage Loan (1) the Master Servicer shall not approve the reimbursement of any Servicing Advance made with respect to such Mortgage Loan prior to the Cut-off Date (each, a “Pre-Cut-off Date Advance”) unless and until it has received a Servicing Advance Schedule listing the amount of Pre-Cut-off Date Advances made in respect of such Mortgage Loan from (a) the related Servicer with respect to any Mortgage Loans that were transferred to such Servicer prior to the Cut-off Date and/or (b) the Depositor with respect to any Mortgage Loans that were transferred to the related Servicer after the Cut-off Date, as applicable, (2) the aggregate Pre-Cut-off Date Advances reimbursable hereunder with respect to such Mortgage Loan shall not exceed the amount of Pre-Cut-off Date Advances for such Mortgage Loan shown on the Servicing Advance Schedule delivered to the Master Servicer, (3) the Depositor shall be deemed to have agreed with and approved the Pre-Cut-off Date Advances shown on any Servicing Advance Schedule furnished to the Master Servicer and (4) the Master Servicer will have no liability to the Depositor, any Servicer or any other Person, including any Certificateholder, for approving reimbursement of related Pre-Cut-off Date Advances so long as the aggregate amount of such advances reimbursed hereunder does not exceed of the amount of Pre-Cut-off Date Advances for such Mortgage Loan shown on the Servicing Advance Schedule.

Notwithstanding anything in this Agreement to the contrary, the related Servicer may not make any future advances with respect to a Mortgage Loan and the

related Servicer shall not permit any modification with respect to any Mortgage Loan serviced by such Servicer that would change the Mortgage Rate, reduce or increase the principal balance (except for reductions resulting from actual payments of principal) or change the final maturity date on such related Mortgage Loan (unless, as provided in Section 3.06 of this Agreement, the related Mortgagor is in default with respect to the related Mortgage Loan or such default is, in the judgment of the related Servicer, reasonably foreseeable) or any modification, waiver or amendment of any term of any Mortgage Loan that would both (A) effect an exchange or reissuance of such Mortgage Loan under Section 1001 of the Code (or final, temporary or proposed Treasury regulations promulgated thereunder) and (B) cause any Trust REMIC created hereunder to fail to qualify as a REMIC under the Code or the imposition of any tax on “prohibited transactions” or “contributions after the startup date” under the REMIC Provisions.

In the event that the Mortgage Loan Documents relating to any Mortgage Loan contain provisions requiring the related Mortgagor to arbitrate disputes (at the option of the Trustee, on behalf of the Trust), the Trustee hereby authorizes the related Servicer to waive the Trustee’s right or option to arbitrate disputes and to send written notice of such waiver to the Mortgagor, although the Mortgagor may still require arbitration at its option.

SECTION 3.02 Sub-Servicing Agreement Between Each Servicer and Sub-Servicers.

Each Servicer may arrange for the subservicing of any Mortgage Loan by a Sub-Servicer pursuant to a Sub-Servicing Agreement; provided that such sub-servicing arrangement and the terms of the related Sub-Servicing Agreement must provide for the servicing of such Mortgage Loans in a manner consistent with the servicing arrangements contemplated hereunder. Each Sub-Servicer shall be (i) authorized to transact business in the state or states where the related Mortgaged Properties it is to service are situated, if and to the extent required by applicable law to enable the Sub-Servicer to perform its obligations hereunder and under the Sub-Servicing Agreement and (ii) a Xxxxxxx Mac or Xxxxxx Mae approved mortgage servicer. Notwithstanding the provisions of any Sub-Servicing Agreement, any of the provisions of this Agreement relating to agreements or arrangements between the related Servicer or a Sub-Servicer or reference to actions taken through the related Servicer or otherwise, the related Servicer shall remain obligated and liable to the Depositor, the Trustee and the Certificateholders for the servicing and administration of the Mortgage Loans in accordance with the provisions of this Agreement without diminution of such obligation or liability by virtue of such Sub-Servicing Agreement or arrangements or by virtue of indemnification from the Sub-Servicer and to the same extent and under the same terms and conditions as if the related Servicer alone were servicing and administering the Mortgage Loans. Every Sub-Servicing Agreement entered into by the related Servicer shall contain a provision giving the successor Servicer the option to terminate such agreement in the event a successor Servicer is appointed. All actions of each Sub-Servicer performed pursuant to the related Sub-Servicing Agreement shall be performed as an agent of the related Servicer with the same force and effect as if performed directly by the related Servicer.

For purposes of this Agreement, the related Servicer shall be deemed to have received any collections, recoveries or payments with respect to the Mortgage Loans that are received by a Sub-Servicer regardless of whether such payments are remitted by the Sub-Servicer to such Servicer.

SECTION 3.03

Successor Sub-Servicers.

Any Sub-Servicing Agreement shall provide that the related Servicer shall be entitled to terminate any Sub-Servicing Agreement and to either itself directly service the related Mortgage Loans or enter into a Sub-Servicing Agreement with a successor Sub-Servicer which qualifies under Section 3.02 of this Agreement. Any Sub-Servicing Agreement shall include the provision that such agreement may be immediately terminated by any successor to the Servicer (which may be the Trustee or the Master Servicer) without fee, in accordance with the terms of this Agreement, in the event that the related Servicer (or any successor to such Servicer) shall, for any reason, no longer be the related Servicer of the Mortgage Loans (including termination due to a Servicer Event of Default).

SECTION 3.04 No Contractual Relationship Between Sub-Servicer, Trustee or the Certificateholders.

Any Sub-Servicing Agreement and any other transactions or services relating to the Mortgage Loans involving a Sub-Servicer shall be deemed to be between the Sub-Servicer and the related Servicer alone, and the Master Servicer, the Trustee and the Certificateholders shall not be deemed parties thereto and shall have no claims, rights, obligations, duties or liabilities with respect to any Sub-Servicer except as set forth in Section 3.05 of this Agreement.

SECTION 3.05 Assumption or Termination of Sub-Servicing Agreement by Successor Servicer.

In connection with the assumption of the responsibilities, duties and liabilities and of the authority, power and rights of the related Servicer hereunder by a successor Servicer (which may be the Trustee or the Master Servicer) pursuant to Section 8.02 of this Agreement, it is understood and agreed that the related Servicer’s rights and obligations under any Sub-Servicing Agreement then in force between the related Servicer and a Sub-Servicer shall be assumed simultaneously by such successor Servicer without act or deed on the part of such successor Servicer; provided, however, that any successor Servicer may terminate the Sub-Servicer.

The related Servicer shall, upon the reasonable request of the Master Servicer, but at its own expense, deliver to the assuming party documents and records relating to each Sub-Servicing Agreement and an accounting of amounts collected and held by it and otherwise use its best efforts to effect the orderly and efficient transfer of the Sub-Servicing Agreement to the assuming party.

The Servicing Fee payable to any such successor Servicer shall be payable from payments received on the Mortgage Loans in the amount and in the manner set forth in this Agreement.

SECTION 3.06

Collection of Certain Mortgage Loan Payments.

Each Servicer shall make reasonable efforts to collect all payments called for under the terms and provisions of the related Mortgage Loans, and shall, to the extent such procedures shall be consistent with this Agreement and Accepted Servicing Practices, follow such collection procedures as it would follow with respect to mortgage loans comparable to the Mortgage Loans and held for its own account. Consistent with the foregoing, each Servicer may in its discretion (i) waive any late payment charge or, if applicable, penalty interest or (ii) extend the due dates for the Monthly Payments due on a Mortgage Note for a period of not greater than one-hundred and eighty (180) days; provided that any extension pursuant to this clause shall not affect the amortization schedule of any Mortgage Loan for purposes of any computation hereunder. Notwithstanding the foregoing, in the event that any Mortgage Loan is in default or, in the judgment of the related Servicer, such default is reasonably foreseeable, the related Servicer, consistent with Accepted Servicing Practices may waive, modify or vary any term of such Mortgage Loan (including modifications that change the Mortgage Rate, forgive the payment of principal or interest or extend the final maturity date of such Mortgage Loan), accept payment from the related Mortgagor of an amount less than the Scheduled Principal Balance in final satisfaction of such Mortgage Loan, or consent to the postponement of strict compliance with any such term or otherwise grant indulgence to any Mortgagor if in the related Servicer’s determination such waiver, modification, postponement or indulgence is not materially adverse to the interests of the Certificateholders (taking into account any estimated Realized Loss that might result absent such action).

SECTION 3.07 Collection of Taxes, Assessments and Similar Items; Servicing Accounts.

To the extent the terms of a Mortgage provide for Escrow Payments, the related Servicer shall establish and maintain one or more accounts (the “Servicing Accounts”), into which all collections from the related Mortgagors (or related advances from Sub-Servicers) for the payment of taxes, assessments, fire, flood, and hazard insurance premiums, and comparable items for the account of the Mortgagors (“Escrow Payments”) shall be deposited and retained. Servicing Accounts shall be Eligible Accounts. The related Servicer shall deposit in the clearing account in which it customarily deposits payments and collections on mortgage loans in connection with its mortgage loan servicing activities on a daily basis, and in no event more than one Business Day after the related Servicer’s receipt thereof, all Escrow Payments collected on account of the related Mortgage Loans and shall thereafter deposit such Escrow Payments in the Servicing Accounts, in no event later than the second Business Day after the deposit of good funds into the clearing account, and retain therein, all Escrow Payments collected on account of the Mortgage Loans, for the purpose of effecting the timely payment of any such items as required under the terms of this Agreement.

Withdrawals of amounts from a Servicing Account may be made only to (i) effect timely payment of taxes, assessments, fire, flood, and hazard insurance premiums, and comparable items; (ii) reimburse itself out of related collections for any Servicing Advances made prior to the Cut-off Date by the Seller or the related Servicer to the extent not previously reimbursed or following the Cut-off Date by the related Servicer pursuant to Section 3.01 of this Agreement (with respect to taxes and assessments) and Section 3.11 of this Agreement (with respect to fire, flood and hazard insurance); (iii) refund to Mortgagors any sums as may be determined to be overages; (iv) pay interest, if required and as described below, to Mortgagors on balances in the Servicing Account; or (v) clear and terminate the Servicing Account at the termination of the related Servicer’s obligations and responsibilities in respect of the related Mortgage Loans under this Agreement in accordance with Article X. As part of its servicing duties, the related Servicer shall pay to the Mortgagors interest on funds in Servicing Accounts, to the extent required by law and, to the extent that interest earned on funds in the Servicing Accounts is insufficient, to pay such interest from its or their own funds, without any reimbursement therefor. Notwithstanding the foregoing, the Servicers shall not be obligated to collect Escrow Payments if the related Mortgage Loan does not require such payments, but the related Servicer shall nevertheless be obligated to make Servicing Advances as provided in Section 3.01 and Section 3.11 of this Agreement. In the event a Servicer shall deposit in the Servicing Accounts any amount not required to be deposited therein, it may at any time withdraw such amount from the related Servicing Accounts, any provision to the contrary notwithstanding.

To the extent that a Mortgage does not provide for Escrow Payments, the related Servicer (i) shall determine whether any such payments are made by the Mortgagor in a manner and at a time that is necessary to avoid the loss of the Mortgaged Property due to a tax sale or the foreclosure as a result of a tax lien and (ii) shall ensure that all insurance required to be maintained on the Mortgaged Property pursuant to this Agreement is maintained. If any such payment has not been made and the related Servicer receives notice of a tax lien with respect to the Mortgage Loan being imposed, the related Servicer shall, promptly and to the extent required to avoid loss of the Mortgaged Property, advance or cause to be advanced funds necessary to discharge such lien on the Mortgaged Property unless the related Servicer determines the advance to be nonrecoverable. Each Servicer assumes full responsibility for the payment of all such bills and shall effect payments of all such bills irrespective of the Mortgagor’s faithful performance in the payment of same or the making of the Escrow Payments and shall make Servicing Advances to effect such payments subject to its determination of recoverability.

SECTION 3.08 Collection Account, Simple Interest Excess Sub-Account and Distribution Account.

(a) On behalf of the Trust Fund, each Servicer shall establish and maintain one or more “Collection Accounts”, held in trust for the benefit of the Trustee and the Certificateholders. On behalf of the Trust Fund, each Servicer shall deposit or cause to be deposited in the clearing account in which it customarily deposits payments and collections on mortgage loans in connection with its mortgage loan servicing

activities on a daily basis, and in no event more than one (1) Business Day after such Servicer’s receipt thereof, and shall thereafter deposit in the related Collection Account, in no event later than two (2) Business Days after the deposit of good funds into the clearing account, as and when received or as otherwise required hereunder, the following payments and collections received or made by it on or subsequent to the Cut-off Date:

(i) all payments on account of principal, including Principal Prepayments, on the related Mortgage Loans;

(ii) all payments on account of interest (net of the related Servicing Fee and any Prepayment Interest Excess) on each related Mortgage Loan;

(iii) all Insurance Proceeds and Liquidation Proceeds (other than proceeds collected in respect of any particular REO Property) and all Subsequent Recoveries with respect to the related Mortgage Loans;

(iv) any amounts required to be deposited by the related Servicer pursuant to Section 3.10 of this Agreement in connection with any losses realized on Permitted Investments with respect to funds held in the related Collection Account;

(v) any amounts required to be deposited by the related Servicer pursuant to the second paragraph of Section 3.11(a) of this Agreement in respect of any blanket policy deductibles;

(vi) any Purchase Price or Substitution Shortfall Amount delivered to the related Servicer and all proceeds (net of amounts payable or reimbursable to the related Servicer, the Master Servicer, the Trustee, the Custodians or the Securities Administrator) of the related Mortgage Loans purchased in accordance with Section 2.03, Section 3.13 or Section 10.01 of this Agreement; and

(vii) any Prepayment Charges collected by the related Servicer in connection with the Principal Prepayment of any of the related Mortgage Loans or amounts required to be deposited by the related Servicer in connection with a breach of its obligations under Section 2.05 of this Agreement.

The foregoing requirements for deposit in the related Collection Account shall be exclusive, it being understood and agreed that, without limiting the generality of the foregoing, payments in the nature of late payment charges, assumption fees or other similar fees need not be deposited by the related Servicer in the related Collection Account and may be retained by the related Servicer as additional servicing compensation. In the event a Servicer shall deposit in the related Collection Account any amount not required to be deposited therein, it may at any time withdraw such amount from such Collection Account, any provision herein to the contrary notwithstanding.

(b) Except as set forth below, no later than the Closing Date, each Servicer servicing Simple Interest Mortgage Loans shall establish and maintain a sub-account of the Collection Account titled “[Servicer’s name], Simple Interest Excess Sub-Account in trust for the Holders of ACE Securities Corp., Home Equity Loan Trust, Series 2005-SD3, Asset Backed Pass-Through Certificates”. The related Servicer shall, on each Determination Date transfer from the Collection Account to the Simple Interest Excess Sub-Account all Net Simple Interest Excess, if any, pursuant to Section 3.09(a)(xi) of this Agreement, and shall maintain a record of all such deposits. In lieu of establishing a Simple Interest Excess Sub-Account, each Servicer may maintain any Net Simple Interest Excess in the Collection Account and maintain a separate accounting therefor.

The related Servicer shall withdraw amounts on deposit in the Simple Interest Excess Sub-Account or in the related Collection Account (in respect of any Net Simple Interest Excess) on each Determination Date for deposit to the Distribution Account in an amount equal to the lesser of (i) the amount on deposit therein, and (ii) the Net Simple Interest Shortfall for such Distribution Date.

The related Servicer shall remit to the Securities Administrator which shall thereupon distribute to the Class CE-1 Certificateholder, based on the information provided to it by the Servicer, the amount of any Net Simple Interest Excess remaining in the Simple Interest Excess Sub-Account or in the related Collection Account, as applicable, on the Distribution Date each year occurring in December, commencing in December 2006. Such distributions shall be deemed to be made on a first-in, first-out basis. In addition, the related Servicer shall clear and terminate the Simple Interest Excess Sub-Account, if any, upon the termination of this Agreement and retain any funds remaining therein.

(c) On behalf of the Trust Fund, the Securities Administrator shall establish and maintain one or more accounts (such account or accounts, the “Distribution Account”), held in trust for the benefit of the Trustee, the Trust Fund and the Certificateholders. On behalf of the Trust Fund, WAMU shall deliver funds to the Securities Administrator for deposit in the Distribution Account as specified in the Servicing Agreement, and Ocwen and Xxxxx Fargo shall deliver to the Securities Administrator in immediately available funds for deposit in the Distribution Account on or before 12:00 noon New York time on the Servicer Remittance Date, that portion of the Available Distribution Amount (calculated without regard to the references in clause (2) of the definition thereof to amounts that may be withdrawn from the Distribution Account) for the related Distribution Date then on deposit in the related Collection Account and the amount of all Prepayment Charges collected by Ocwen or Xxxxx Fargo in connection with the Principal Prepayment of any of the related Mortgage Loans then on deposit in the related Collection Account and the amount of any funds reimbursable to an Advance Financing Person pursuant to Section 3.25 of this Agreement. If the balance on deposit in a Collection Account exceeds $100,000 as of the commencement of business on any Business Day and the Collection Account constitutes an Eligible Account solely pursuant to clause (ii) of the definition of “Eligible Account,” the related Servicer shall, on or before 5:00 p.m. New York time on such Business Day, withdraw

from the related Collection Account any and all amounts payable or reimbursable to the Depositor, such Servicer, the Trustee, the Master Servicer, the Securities Administrator or the Seller pursuant to Section 3.09 of this Agreement and shall pay such amounts to the Persons entitled thereto or shall establish a separate Collection Account (which shall also be an Eligible Account) and withdraw from the existing Collection Account the amount on deposit therein in excess of $100,000 and deposit such excess in the newly created Collection Account.

With respect to any remittance received by the Securities Administrator after the Servicer Remittance Date on which such payment was due, the Securities Administrator shall send written notice thereof to the related Servicer. The related Servicer shall pay to the Securities Administrator interest on any such late payment by such Servicer at an annual rate equal to Prime Rate (as defined in The Wall Street Journal) plus one percentage point, but in no event greater than the maximum amount permitted by applicable law. Such interest shall be paid by the related Servicer to the Securities Administrator on the date such late payment is made and shall cover the period commencing with the day following the Servicer Remittance Date and ending with the Business Day on which such payment is made, both inclusive. The payment by the related Servicer of any such interest, or the failure of the Securities Administrator to notify the related Servicer of such interest, shall not be deemed an extension of time for payment or a waiver of any Event of Default by the related Servicer.

(d) Funds in each Collection Account in each Simple Interest Excess Sub-Account and funds in the Distribution Account may be invested in Permitted Investments in accordance with the provisions set forth in Section 3.10 of this Agreement. The related Servicer shall give notice to the Trustee, the Securities Administrator and the Master Servicer of the location of the Collection Account maintained by it when established and prior to any change thereof. The Securities Administrator shall give notice to the Servicers and the Depositor of the location of the Distribution Account when established and prior to any change thereof.

(e) Funds held in a Collection Account at any time may be delivered by the related Servicer in immediately available funds to the Securities Administrator for deposit in the Distribution Account. In the event a Servicer shall deliver to the Securities Administrator for deposit in the Distribution Account any amount not required to be deposited therein, it may at any time request that the Securities Administrator withdraw such amount from the Distribution Account and remit to it any such amount, any provision herein to the contrary notwithstanding. In no event shall the Securities Administrator incur liability as a result of withdrawals from the Distribution Account at the direction of a Servicer in accordance with the immediately preceding sentence. In addition, each Servicer shall deliver to the Securities Administrator no later than the Servicer Remittance Date the amounts set forth in clauses (i) through (iv) below:

(i) any P&I Advances, as required pursuant to Section 5.03 of this Agreement;

(ii) any amounts required to be deposited pursuant to Section 3.21(d) or 3.21(f) of this Agreement in connection with any REO Property;

(iii) any amounts to be paid in connection with a purchase of Mortgage Loans and REO Properties pursuant to Section 10.01 of this Agreement; and

(iv) any amounts required to be deposited pursuant to Section 3.22 of this Agreement in connection with any Prepayment Interest Shortfalls.

(vi)

to reimburse itself (including any successor Servicer) for

(A) any P&I Advance or Servicing Advance previously made by it, which the related Servicer has determined to be a Nonrecoverable P&I Advance or a Nonrecoverable Servicing Advance in accordance with the provisions of Section 5.03 of this Agreement; provided however, that a Servicer shall not be entitled to reimbursement for any Servicing Advance made prior to the Cut-off Date if such Servicer determines that such Servicing Advance constitutes a Nonrecoverable Servicing Advance;

(B) any unpaid Servicing Fees to the extent not recoverable from Liquidation Proceeds, Insurance Proceeds or other amounts received with respect to the related Mortgage Loan under Section 3.08(iii) of this Agreement; or

Each Servicer shall keep and maintain separate accounting, on a Mortgage Loan by Mortgage Loan basis, for the purpose of justifying any withdrawal from the related Collection Account, to the extent held by or on behalf of it, pursuant to subclauses (ii), (iii), (v), (vi), (vii), (viii), (ix), (x) and (xi) above.

SECTION 3.10

Investment of Funds in the Investment Accounts.

(a) Each Servicer may direct, by means of written directions (which may be standing directions), any depository institution maintaining the related Collection

Account or Simple Interest Excess Sub-Account to invest the funds in such Collection Account or Simple Interest Excess Sub-Account (for purposes of this Section 3.10, an “Investment Account”) in one or more Permitted Investments bearing interest or sold at a discount, and maturing, unless payable on demand, (i) no later than the Business Day immediately preceding the date on which such funds are required to be withdrawn from such account pursuant to this Agreement, if a Person other than the Securities Administrator is the obligor thereon, and (ii) no later than the date on which such funds are required to be withdrawn from such account pursuant to this Agreement, if the Securities Administrator is the obligor on such Permitted Investment. Amounts in the Distribution Account may be invested in Permitted Investments as directed in writing by the Master Servicer and maturing, unless payable on demand, (i) no later than the Business Day immediately preceding the date on which such funds are required to be withdrawn from such account pursuant to this Agreement, if a Person other than the Securities Administrator is the obligor thereon, and (ii) no later than the date on which such funds are required to be withdrawn from such account pursuant to this Agreement, if the Securities Administrator is the obligor thereon. All such Permitted Investments shall be held to maturity, unless payable on demand. Any investment of funds shall be made in the name of the Trustee (in its capacity as such) or in the name of a nominee of the Trustee. The Securities Administrator shall be entitled to sole possession over each such investment in the Distribution Account and, subject to subsection (b) below, the income thereon, and any certificate or other instrument evidencing any such investment shall be delivered directly to the Securities Administrator or its agent, together with any document of transfer necessary to transfer title to such investment to the Trustee or its nominee. In the event amounts on deposit in a Collection Account are at any time invested in a Permitted Investment payable on demand, the party with investment discretion over such Investment Account shall:

(x) consistent with any notice required to be given thereunder, demand that payment thereon be made on the last day such Permitted Investment may otherwise mature hereunder in an amount equal to the lesser of (1) all amounts then payable thereunder and (2) the amount required to be withdrawn on such date; and

(y) demand payment of all amounts due thereunder promptly upon receipt by such party of written notice from the related Servicer that such Permitted Investment would not constitute a Permitted Investment in respect of funds thereafter on deposit in the Investment Account.

(b) All income and gain realized from the investment of funds deposited in the related Collection Account or Simple Interest Excess Sub-Account shall be for the benefit of the related Servicer and shall be subject to its withdrawal in accordance with Section 3.09 of this Agreement. Each Servicer shall deposit in the related Collection Account or Simple Interest Excess Sub-Account the amount of any loss incurred in respect of any such Permitted Investment made with funds in such account immediately upon realization of such loss. All earnings and gain realized from the investment of funds deposited in the Distribution Account shall be for the benefit of the Master Servicer. The Master Servicer shall remit from its own funds for deposit into

the Distribution Account the amount of any loss incurred on Permitted Investments in the Distribution Account.

(c) Except as otherwise expressly provided in this Agreement, if any default occurs in the making of a payment due under any Permitted Investment, or if a default occurs in any other performance required under any Permitted Investment, the Trustee may and, subject to Section 9.01 and Section 9.02(a)(v) of this Agreement, shall, at the written direction of the related Servicer, take such action as may be appropriate to enforce such payment or performance, including the institution and prosecution of appropriate proceedings.

(d) The Trustee, the Master Servicer or their respective Affiliates are permitted to receive additional compensation that could be deemed to be in the Trustee’s or the Master Servicer’s economic self-interest for (i) serving as investment adviser, administrator, shareholder servicing agent, custodian or sub-custodian with respect to certain of the Permitted Investments, (ii) using Affiliates to effect transactions in certain Permitted Investments and (iii) effecting transactions in certain Permitted Investments. Such compensation shall not be considered an amount that is reimbursable or payable to the Trustee or the Master Servicer pursuant to Section 3.09 or Section 3.10 of this Agreement or otherwise payable in respect of Extraordinary Trust Fund Expenses. Such additional compensation shall not be an expense of the Trust Fund.

SECTION 3.11 Maintenance of Hazard Insurance, Errors and Omissions and Fidelity Coverage and Primary Mortgage Insurance.

(a) The terms of each Mortgage Note require the related Mortgagor to maintain fire, flood and hazard insurance policies. To the extent such policies are not maintained, the related Servicer shall cause to be maintained for each Mortgaged Property related to a Mortgage Loan serviced by such Servicer fire and hazard insurance with extended coverage as is customary in the area where the Mortgaged Property is located in an amount which is at least equal to the lesser of the current principal balance of such Mortgage Loan and the amount necessary to compensate fully for any damage or loss to the improvements which are a part of such property on a replacement cost basis, in each case in an amount not less than such amount as is necessary to avoid the application of any coinsurance clause contained in the related hazard insurance policy. Each Servicer shall also cause to be maintained fire and hazard insurance on each REO Property with extended coverage as is customary in the area where the Mortgaged Property is located in an amount which is at least equal to the lesser of (i) the maximum insurable value of the improvements which are a part of such property and (ii) the outstanding principal balance of the related Mortgage Loan at the time it became an REO Property. Each Servicer will comply in the performance of this Agreement with all reasonable rules and requirements of each insurer under any such hazard policies. Any amounts to be collected by the related Servicer under any such policies (other than amounts to be applied to the restoration or repair of the property subject to the related Mortgage or amounts to be released to the Mortgagor in accordance with Accepted Servicing Practices, subject to the terms and conditions of the related Mortgage and Mortgage Note) shall be deposited in the related Collection Account, subject to withdrawal pursuant to Section 3.09 of this

Agreement, if received in respect of a Mortgage Loan, or in the REO Account, subject to withdrawal pursuant to Section 3.21 of this Agreement, if received in respect of an REO Property. Any cost incurred by a Servicer in maintaining any such insurance shall not, for the purpose of calculating distributions to Certificateholders, be added to the unpaid principal balance of the related Mortgage Loan, notwithstanding that the terms of such Mortgage Loan so permit. It is understood and agreed that no earthquake or other additional insurance is to be required of any Mortgagor other than pursuant to such applicable laws and regulations as shall at any time be in force and as shall require such additional insurance. If the Mortgaged Property or REO Property is at any time in an area identified in the Federal Register by the Federal Emergency Management Agency as having special flood hazards, the related Servicer will cause to be maintained a flood insurance policy in respect thereof. Such flood insurance shall be in an amount equal to the lesser of (i) the unpaid principal balance of the related Mortgage Loan and (ii) the maximum amount of such insurance available for the related Mortgaged Property under the national flood insurance program (assuming that the area in which such Mortgaged Property is located is participating in such program).

In the event that a Servicer shall obtain and maintain a blanket policy with an insurer having a General Policy Rating of B:VI or better in Best’s Key Rating Guide or otherwise acceptable to Xxxxxx Xxx or Xxxxxxx Mac insuring against hazard losses on all of the Mortgage Loans, it shall conclusively be deemed to have satisfied its obligations to cause fire and hazard insurance to be maintained on the Mortgaged Properties, it being understood and agreed that such policy may contain a deductible clause, in which case the related Servicer shall, in the event that there shall not have been maintained on the related Mortgaged Property or REO Property a policy complying with the first two sentences of this Section 3.11, and there shall have been one or more losses which would have been covered by such policy, deposit to the related Collection Account from its own funds the amount not otherwise payable under the blanket policy because of such deductible clause. In connection with its activities as administrator and servicer of the Mortgage Loans, the related Servicer agrees to prepare and present, on behalf of itself, the Trustee, the Trust Fund and the Certificateholders, claims under any such blanket policy in a timely fashion in accordance with the terms of such policy.

(b) Each Servicer shall keep in force during the term of this Agreement a policy or policies of insurance covering errors and omissions for failure in the performance of its respective obligations under this Agreement, which policy or policies shall be in such form and amount that would meet the requirements of Xxxxxx Mae or Xxxxxxx Mac if it were the purchaser of the Mortgage Loans, unless the related Servicer has obtained a waiver of such requirements from Xxxxxx Mae or Xxxxxxx Mac. Each Servicer shall also maintain a fidelity bond in the form and amount that would meet the requirements of Xxxxxx Mae or Xxxxxxx Mac, unless the related Servicer has obtained a waiver of such requirements from Xxxxxx Mae or Xxxxxxx Mac. A Servicer shall be deemed to have complied with this provision if an Affiliate of such Servicer, has such errors and omissions and fidelity bond coverage and, by the terms of such insurance policy or fidelity bond, the coverage afforded thereunder extends to such Servicer. Any such errors and omissions policy and fidelity bond shall by its terms not be cancelable without thirty days’ prior written notice to the Trustee.

(c) The Servicers shall not take any action that would result in noncoverage under any applicable primary mortgage insurance policy of any loss which, but for the actions of the related Servicer would have been covered thereunder. Each Servicer shall use its best efforts to keep in force and effect any applicable primary mortgage insurance policy and, to the extent that the related Mortgage Loan requires the Mortgagor to maintain such insurance, any other primary mortgage insurance applicable to any Mortgage Loan. Except as required by applicable law or the related Mortgage Loan Documents, the Servicers shall not cancel or refuse to renew any such primary mortgage insurance policy that is in effect at the date of the initial issuance of the related Mortgage Note and is required to be kept in force hereunder.

Each Servicer agrees to present on behalf of the Trustee and the Certificateholders claims to the applicable insurer under any primary mortgage insurance policies and, in this regard, to take such reasonable action as shall be necessary to permit recovery under any primary mortgage insurance policies respecting defaulted Mortgage Loans. Pursuant to Section 3.08 of this Agreement, any amounts collected by a Servicer under any primary mortgage insurance policies shall be deposited in the related Collection Account, subject to withdrawal pursuant to Section 3.09 of this Agreement. Notwithstanding any provision to the contrary, a Servicer shall not have any responsibility with respect to a primary mortgage insurance policy unless such Servicer has been made aware of such policy, as reflected on the Mortgage Loan Schedule or otherwise and have been provided with adequate information to administer such policy.

SECTION 3.12 Enforcement of Due-on-Sale Clauses; Assumption Agreements.

Each Servicer shall, to the extent it has knowledge of any conveyance of any Mortgaged Property by any related Mortgagor (whether by absolute conveyance or by contract of sale, and whether or not the Mortgagor remains or is to remain liable under the Mortgage Note and/or the Mortgage), exercise its rights to accelerate the maturity of such Mortgage Loan under the “due-on-sale” clause, if any, applicable thereto; provided, however, that the related Servicer shall not exercise any such rights if prohibited by law from doing so. If a Servicer reasonably believes that it is unable under applicable law to enforce such “due-on-sale” clause, or if any of the other conditions set forth in the proviso to the preceding sentence apply, the related Servicer shall make reasonable efforts to enter into an assumption and modification agreement from or with the person to whom such property has been conveyed or is proposed to be conveyed, pursuant to which such person becomes liable under the Mortgage Note and, to the extent permitted by applicable state law, the Mortgagor remains liable thereon. The related Servicer is also authorized to enter into a substitution of liability agreement with such person, pursuant to which the original Mortgagor is released from liability and such person is substituted as the Mortgagor and becomes liable under the Mortgage Note, provided that no such substitution shall be effective unless such person satisfies the then current underwriting criteria of the related Servicer for mortgage loans similar to the Mortgage Loans. In connection with any assumption or substitution, the related Servicer shall apply such underwriting standards and follow such practices and procedures as shall be normal and usual in its general mortgage servicing activities and as it applies to other mortgage loans

owned solely by it. The related Servicer shall not take or enter into any assumption and modification agreement, however, unless (to the extent practicable in the circumstances) it shall have received confirmation, in writing, of the continued effectiveness of any applicable hazard insurance policy. Any fee collected by the related Servicer in respect of an assumption or substitution of liability agreement will be retained by such Servicer as additional servicing compensation. In connection with any such assumption, no material term of the Mortgage Note (including but not limited to the related Mortgage Rate and the amount of the Monthly Payment) may be amended or modified, except as otherwise required pursuant to the terms thereof. The related Servicer shall notify the Trustee (or the applicable Custodian) that any such substitution or assumption agreement has been completed by forwarding to the Trustee (or the applicable Custodian) the executed original of such substitution or assumption agreement, which document shall be added to the related Mortgage File and shall, for all purposes, be considered a part of such Mortgage File to the same extent as all other documents and instruments constituting a part thereof.

Notwithstanding the foregoing paragraph or any other provision of this Agreement, the related Servicer shall not be deemed to be in default, breach or any other violation of its obligations hereunder by reason of any assumption of a Mortgage Loan by operation of law or by the terms of the Mortgage Note or any assumption which the related Servicer may be restricted by law from preventing, for any reason whatever. For purposes of this Section 3.12, the term “assumption” is deemed to also include a sale (of the Mortgaged Property) subject to the Mortgage that is not accompanied by an assumption or substitution of liability agreement.

SECTION 3.13

Realization Upon Defaulted Mortgage Loans.

(a) Each Servicer shall use its best efforts, consistent with Accepted Servicing Practices, to foreclose upon or otherwise comparably convert the ownership of properties securing such of the Mortgage Loans as come into and continue in default and as to which no satisfactory arrangements can be made for collection of delinquent payments pursuant to Section 3.06 of this Agreement. Each Servicer shall be responsible for all costs and expenses incurred by it in any such proceedings; provided, however, that such costs and expenses will be recoverable as Servicing Advances by the related Servicer as contemplated in Section 3.09 and Section 3.21 of this Agreement. The foregoing is subject to the provision that, in any case in which a Mortgaged Property shall have suffered damage from an Uninsured Cause, the related Servicer shall not be required to expend its own funds toward the restoration of such property unless it shall determine in its discretion that such restoration will increase the proceeds of liquidation of the related Mortgage Loan after reimbursement to itself for such expenses.

(b) Notwithstanding the foregoing provisions of this Section 3.13 or any other provision of this Agreement, with respect to any Mortgage Loan as to which a Servicer has received actual notice of, or has actual knowledge of, the presence of any toxic or hazardous substance on the related Mortgaged Property, such Servicer shall not, on behalf of the Trust Fund, either (i) obtain title to such Mortgaged Property as a result of or in lieu of foreclosure or otherwise, or (ii) otherwise acquire possession of, or take

any other action with respect to, such Mortgaged Property, if, as a result of any such action, the Trust Fund, the Trustee or the Certificateholders would be considered to hold title to, to be a “mortgagee-in-possession” of, or to be an “owner” or “operator” of such Mortgaged Property within the meaning of the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended from time to time, or any comparable law, unless such Servicer has also previously determined, based on its reasonable judgment and a prudent report prepared by an Independent Person who regularly conducts environmental audits using customary industry standards, that:

(1) such Mortgaged Property is in compliance with applicable environmental laws or, if not, that it would be in the best economic interest of the Trust Fund to take such actions as are necessary to bring the Mortgaged Property into compliance therewith; and

(2) there are no circumstances present at such Mortgaged Property relating to the use, management or disposal of any hazardous substances, hazardous materials, hazardous wastes or petroleum-based materials for which investigation, testing, monitoring, containment, clean-up or remediation could be required under any federal, state or local law or regulation, or that if any such materials are present for which such action could be required, that it would be in the best economic interest of the Trust Fund to take such actions with respect to the affected Mortgaged Property.

The cost of the environmental audit report contemplated by this Section 3.13 shall be advanced by the related Servicer, subject to such Servicer’s right to be reimbursed therefor from the related Collection Account as provided in Section 3.09(a)(ix) of this Agreement, such right of reimbursement being prior to the rights of Certificateholders to receive any amount in the related Collection Account received in respect of the affected Mortgage Loan or other Mortgage Loans.

If the related Servicer determines, as described above, that it is in the best economic interest of the Trust Fund to take such actions as are necessary to bring any such Mortgaged Property into compliance with applicable environmental laws, or to take such action with respect to the containment, clean-up or remediation of hazardous substances, hazardous materials, hazardous wastes, or petroleum-based materials affecting any such Mortgaged Property, then such Servicer shall take such action as it deems to be in the best economic interest of the Trust Fund. The cost of any such compliance, containment, cleanup or remediation shall be advanced by the related Servicer, subject to such Servicer’s right to be reimbursed therefor from the Collection Account as provided in Section 3.09(a)(iii) or Section 3.09(a)(ix) of this Agreement, such right of reimbursement being prior to the rights of Certificateholders to receive any amount in the related Collection Account received in respect of the affected Mortgage Loan or other Mortgage Loans.

(c) The Class CE-1 Certificateholder shall have the right to purchase from REMIC I any Mortgage Loan which was not delinquent as of the Closing Date but

which becomes delinquent in payment by 90 days or more and, in the event that the Class CE-1 Certificateholder fails to exercise such option, Ocwen shall have the right to purchase from REMIC I any such Mortgage Loan that is an Ocwen Mortgage Loan and which Ocwen determines in good faith will otherwise become subject to foreclosure proceedings (evidence of such determination to be delivered in writing to the Trustee, in form and substance satisfactory to Ocwen and the Trustee prior to purchase). The Purchase Price for any Mortgage Loan purchased pursuant to this clause (c) shall be (i) remitted to the Securities Administrator for deposit into the Distribution Account with respect to a purchase by the Class CE-1 Certificateholder or (ii) deposited in the related Collection Account with respect to a purchase by Ocwen, and the Trustee, upon receipt of written certification from the Securities Administrator or Ocwen, as applicable, of such deposit, shall release or cause to be released to the Class CE-1 Certificateholder or Ocwen, as applicable, the related Mortgage File and the Trustee shall execute and deliver such instruments of transfer or assignment, in each case without recourse, representation or warranty, as the Class CE-1 Certificateholder or Ocwen, as applicable, shall furnish and as shall be necessary to vest in the Class CE-1 Certificateholder or Ocwen, as applicable, title to any Mortgage Loan released pursuant hereto.

(d) Proceeds received in connection with any Final Recovery Determination, as well as any recovery resulting from a partial collection of Insurance Proceeds or Liquidation Proceeds, in respect of any Mortgage Loan, will be applied in the following order of priority: first, to reimburse the related Servicer for any related unreimbursed Servicing Advances and P&I Advances, pursuant to Section 3.09(a)(ii) or Section 3.09(a)(iii) of this Agreement; second, to accrued and unpaid interest on the Mortgage Loan, to the date of the Final Recovery Determination, or to the Due Date prior to the Distribution Date on which such amounts are to be distributed if not in connection with a Final Recovery Determination; and third, as a recovery of principal of the Mortgage Loan. If the amount of the recovery so allocated to interest is less than the full amount of accrued and unpaid interest due on such Mortgage Loan, the amount of such recovery will be allocated by the related Servicer as follows: first, to unpaid Servicing Fees; and second, to the balance of the interest then due and owing. The portion of the recovery so allocated to unpaid Servicing Fees shall be reimbursed to the related Servicer pursuant to Section 3.09(a)(iii) of this Agreement. The portion of the recovery allocated to interest (net of unpaid Servicing Fees) and the portion of the recovery allocated to principal of the Mortgage Loan shall be applied as follows: first, to reimburse the related Servicer for any related xxxxxxxxxxxx X&X Advances or Servicing Advances in accordance with Section 3.09(a)(ii) and Section 3.09(a)(iii) of this Agreement and any other amounts reimbursable to such Servicer pursuant to Section 3.09 of this Agreement, and second, as part of the amounts to be transferred to the Distribution Account in accordance with Section 3.08(c) of this Agreement.

(e) Notwithstanding the foregoing provisions of this Section 3.13 or any other provision of this Agreement, neither Ocwen nor Xxxxx Fargo shall acquire title to a Mortgaged Property related to a Foreclosure Restricted Mortgage Loan if acquiring title to such Mortgaged Property would cause the adjusted basis (for federal income tax purposes) of the Mortgaged Properties in respect of Foreclosure Restricted Mortgage Loans that are currently owned by REMIC I after foreclosure (along with any other assets

owned by REMIC I other than “qualified mortgages” and “permitted investments” within the meaning of Section 860G of the Internal Revenue Code) to exceed 0.75% of the adjusted basis of the assets in REMIC I. Instead, such Servicer shall dispose of the Foreclosure Restricted Mortgage Loan for cash in a foreclosure sale. In addition, if such Servicer determines that, following a distribution on any Distribution Date, the adjusted basis of the REO Properties relating to such Foreclosure Restricted Mortgage Loans (along with any other assets owned by REMIC I other than “qualified mortgages” and “permitted investments” within the meaning of Section 860G of the Internal Revenue Code) exceeds 1.0% of the adjusted basis of the assets of REMIC I immediately after the Distribution Date, then prior to the next Distribution Date, such Servicer shall dispose of enough of such REO Properties for cash, so that the adjusted basis of such REO Properties relating to Foreclosure Restricted Mortgage Loans (along with any other assets owned by REMIC I other than “qualified mortgages” and “permitted investments” within the meaning of Section 860G of the Internal Revenue Code) will be less than 1.0% of the adjusted basis of the assets of REMIC I. In either event, such Servicer is permitted to acquire (for its own account and not on behalf of the Trust Fund) the REO Property at the foreclosure sale for an amount not less than the greater of: (i) the highest amount bid by any other person at the foreclosure sale, or (ii) the estimated fair market value of the REO Property, as determined by such Servicer in good faith. These restrictions will be lifted with respect to a Foreclosure Restricted Mortgage Loan if such Mortgage Loan becomes current for three consecutive Monthly Payments.

SECTION 3.14

Trustee to Cooperate; Release of Mortgage Files.

(a) Upon becoming aware of the payment in full of any Mortgage Loan, or the receipt by a 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 related Servicer will promptly furnish to the applicable Custodian, on behalf of the Trustee, two copies of a request for release substantially in the form attached to the related Custodial Agreement 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 related Collection Account have been or will be so deposited) and shall request that such Custodian, on behalf of the Trustee, deliver to the related Servicer the related Mortgage File. Upon receipt of such certification and request, the applicable Custodian, on behalf of the Trustee, shall within five (5) Business Days release the related Mortgage File to the related Servicer and the Trustee and the applicable Custodian shall have no further responsibility with regard to such Mortgage File. Upon any such payment in full, the related Servicer is authorized, to give, as agent for the Trustee, as the mortgagee under the Mortgage that secured the Mortgage Loan, an instrument of satisfaction (or assignment of mortgage without recourse) regarding the Mortgaged Property subject to the Mortgage, which instrument of satisfaction or assignment, as the case may be, shall be delivered to the Person or Persons entitled thereto against receipt therefor of such payment, it being understood and agreed that no expenses incurred in connection with such instrument of satisfaction or assignment, as the case may be, shall be chargeable to the related Collection Account.

(b) From time to time and as appropriate for the servicing or foreclosure of any Mortgage Loan, the Trustee shall execute such documents as shall be prepared and furnished to the Trustee by the related Servicer (in form reasonably acceptable to the Trustee) and as are necessary to the prosecution of any such proceedings. The applicable Custodian, on behalf of the Trustee, shall, upon the request of the related Servicer, and delivery to the applicable Custodian of two copies of a request for release signed by a Servicing Officer substantially in the form attached to the related 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 within five (5) Business Days the related Mortgage File held in its possession or control to the related Servicer. Such trust receipt shall obligate the related Servicer to return the Mortgage File to the applicable Custodian on behalf of the Trustee, when the need therefor by such Servicer no longer exists unless the Mortgage Loan shall be liquidated, in which case, upon receipt of a certificate of a Servicing Officer similar to that hereinabove specified, the Mortgage File shall be released by the applicable Custodian, on behalf of the Trustee, to the related Servicer.

Notwithstanding the foregoing, in connection with a Principal Prepayment in full of any Mortgage Loan, the Master Servicer may request release of the related Mortgage File from the applicable Custodian, in accordance with the provisions of the related Custodial Agreement, in the event the related Servicer fails to do so.

Upon written certification of a Servicing Officer, the Trustee shall execute and deliver to the related Servicer, any court pleadings, requests for trustee’s sale or other documents prepared and delivered to the Trustee and reasonably acceptable to it and necessary to the foreclosure or trustee’s sale in respect of a Mortgaged Property or to any legal action brought to obtain judgment against any Mortgagor on the Mortgage Note or Mortgage or to obtain a deficiency judgment, or to enforce any other remedies or rights provided by the Mortgage Note or Mortgage or otherwise available at law or in equity. Each such certification shall include a request that such pleadings or documents be executed by the Trustee and a statement as to the reason such documents or pleadings are required and that the execution and delivery thereof by the Trustee will not invalidate or otherwise affect the lien of the Mortgage, except for the termination of such a lien upon completion of the foreclosure or trustee’s sale. So long as no Servicer Event of Default shall have occurred and be continuing, the related Servicer shall have the right to execute any and all such court pleadings, requests and other documents as attorney-in-fact for, and on behalf of the Trustee. Notwithstanding the preceding sentence, the Trustee shall in no way be liable or responsible for the willful malfeasance of the Servicer, or for any wrongful or negligent actions taken by the Servicer, while the Servicer is acting in its capacity as attorney-in-fact for and on behalf of the Trustee.

SECTION 3.15

Servicing Compensation.

As compensation for its activities hereunder, Xxxxx Fargo shall be entitled to the Servicing Fee calculated at the Xxxxx Fargo Servicing Fee Rate and Ocwen shall be entitled to a Servicing Fee calculated at the Ocwen Servicing Fee Rate with respect to each Mortgage Loan serviced by such Servicer payable solely from payments of interest

in respect of such Mortgage Loan, subject to Section 3.22 of this Agreement. In addition, the related Servicer shall be entitled to recover unpaid Servicing Fees out of Insurance Proceeds or Liquidation Proceeds to the extent permitted by Section 3.09(a)(iii) of this Agreement and out of amounts derived from the operation and sale of an REO Property to the extent permitted by Section 3.21 of this Agreement. Subject to Section 3.25 of this Agreement, the right to receive the Servicing Fee may not be transferred in whole or in part except in connection with the transfer of all of the related Servicer’s responsibilities and obligations under this Agreement to the extent permitted herein.

Additional servicing compensation in the form of assumption fees, late payment charges, customary real estate referral fees and other miscellaneous fees (other than Prepayment Charges), and ancillary income shall be retained by the related Servicer only to the extent such fees or charges are received by such Servicer. Each Servicer shall also be entitled pursuant to Section 3.09(a)(iv) of this Agreement to withdraw from the related Collection Account and pursuant to Section 3.21(b) of this Agreement to withdraw from any REO Account, as additional servicing compensation, interest or other income earned on deposits therein, subject to Section 3.10 of this Agreement. In addition, each Servicer shall be entitled to retain or withdraw from the related Collection Account, pursuant to Section 3.09(a)(x) of this Agreement, any Prepayment Interest Excess with respect to the Mortgage Loans serviced by it as additional servicing compensation. Each Servicer shall be required to pay all expenses incurred by it in connection with its servicing activities hereunder and shall not be entitled to reimbursement therefor except as specifically provided herein.

SECTION 3.16

The Master Servicer shall forward the statement provided by Xxxxx Fargo pursuant to the preceding sentence to the Securities Administrator, the Trustee and the Depositor, upon request, within a reasonable time after its receipt of such statement from Xxxxx Fargo. Copies of such statement and any similar statements provided by the Servicers shall be provided by the Securities Administrator to any Certificateholder and to any Person identified to the Securities Administrator as a prospective transferee of a Certificate, upon request at the expense of the requesting party, provided such statement is delivered by the related Servicer to the Securities Administrator.

SECTION 3.17

Statement as to Compliance.

Not later than March 15th of each calendar year commencing in 2006, each Servicer shall deliver to the Master Servicer and with respect to Ocwen, to the Trustee and the Depositor, an Officers’ Certificate in a form acceptable for filing with the Securities and Exchange Commission as an exhibit to Form 10-K or other required form (upon which the Master Servicer can conclusively rely in connection with its obligations under Section 5.06 of this Agreement) stating, as to each signatory thereof, that (i) a review of the activities of such Servicer during the preceding year and of performance under this Agreement has been made under such officers’ supervision and (ii) to the best of such officer’s knowledge, based on such review, such Servicer has fulfilled all of its obligations in all material respects under this Agreement throughout such year, or, if there has been a default in the fulfillment of any such material obligation, specifying each such default known to such officer and the nature and status thereof. The Master Servicer shall forward the statement provided by Xxxxx Fargo pursuant to the preceding sentence to the Trustee and the Depositor, upon request, within a reasonable time after its receipt of such statement from Xxxxx Fargo. Copies of any such statement shall be provided by the Trustee to any Certificateholder, upon request at the expense of the requesting party, provided such statement is delivered by the related Servicer to the Trustee.

SECTION 3.18

Independent Public Accountants’ Servicing Report.

Not later than March 15th of each calendar year commencing in 2006, each Servicer, at its expense, shall cause a nationally recognized firm of independent certified public accountants to furnish to such Servicer a report in a form acceptable for filing with the Securities and Exchange Commission as an exhibit to Form 10-K or other required form stating that (i) it has obtained a letter of representation regarding certain matters from the management of such Servicer which includes an assertion that such Servicer has complied with certain minimum residential mortgage loan servicing standards, identified in the Uniform Single Attestation Program for Mortgage Bankers established by the Mortgage Bankers Association of America, with respect to the servicing of residential mortgage loans during the most recently completed fiscal year and (ii) on the basis of an examination conducted by such firm in accordance with standards established by the American Institute of Certified Public Accountants, such representation is fairly stated and such firm has determined that such Servicer has complied in all material respects, subject to such exceptions and other qualifications that may be appropriate. Immediately upon receipt of such report, such Servicer shall furnish a copy of such report to the Master Servicer and with respect to Ocwen to the Trustee and each Rating Agency. The Master Servicer shall forward the statement provided by Xxxxx Fargo pursuant to the preceding sentence to the Trustee and each Rating Agency, upon request, within a reasonable time after its receipt of such statement from Xxxxx Fargo. Copies of such statement shall be provided by the Trustee to any Certificateholder upon request at the related Servicer’s expense, provided that such statement is delivered by the related Servicer to the Trustee.

SECTION 3.19

Annual Certification.

(a) Each Servicer shall deliver to the Master Servicer, on or before March 15th of each calendar year beginning in 2006 (or, if any such day is not a Business Day, the immediately preceding Business Day) or such alternative date reasonably specified by the Master Servicer which shall occur not later than 15 days prior to the date any Form 10-K is required to be filed with the Commission in connection with the transactions contemplated by this Agreement, a certification in the form attached hereto as Exhibit C. Such certification shall be signed by the senior officer in charge of servicing of the related Servicer. In addition, each Servicer shall provide such other information with respect to the Mortgage Loans and the servicing and administration thereof within the control of such Servicer which shall be required to enable the Master Servicer to comply with the reporting requirements of the Securities and Exchange Act of 1934, as amended, pursuant to Section 5.06 hereof.

(b) The related Servicer shall indemnify and hold harmless the Master Servicer, the Securities Administrator, the Trustee, the Depositor and their respective officers, directors, agents and affiliates from and against any losses, damages, penalties, fines, forfeitures, reasonable legal fees and related costs, judgments and other costs and expenses arising out of or based upon a breach by such Servicer or any of its officers, directors, agents or affiliates of its obligations under this Section 3.19 or such Servicer’s negligence, bad faith or willful misconduct in connection therewith. Such indemnity shall survive the termination or resignation of the parties hereto or the termination of this Agreement. If the indemnification provided for herein is unavailable or insufficient to hold harmless the Master Servicer, the Securities Administrator, the Trustee and the Depositor, then the related Servicer agrees that it shall contribute to the amount paid or payable by the Master Servicer, the Securities Administrator, the Trustee and the Depositor as a result of the losses, claims, damages or liabilities of the Master Servicer, the Securities Administrator, the Trustee and the Depositor in such proportion as is appropriate to reflect the relative fault of the Master Servicer, the Securities Administrator, the Trustee and the Depositor on the one hand and the related Servicer on the other in connection with a breach of such Servicer’s obligations under this Section 3.19.

SECTION 3.20

Access to Certain Documentation.

Each Servicer shall provide to the Office of Thrift Supervision, the FDIC, and any other federal or state banking or insurance regulatory authority that may exercise authority over any Certificate Owner, access to the documentation regarding the Mortgage Loans required by applicable laws and regulations. Such access shall be afforded without charge, but only upon reasonable request and during normal business hours at the offices of the related Servicer designated by it. Nothing in this Section 3.20 shall limit the obligation of the related Servicer to comply with any applicable law prohibiting disclosure of information regarding the Mortgagors and the failure of such Servicer to provide access as provided in this Section as a result of such obligation shall not constitute a breach of this Section. Nothing in this Section 3.20 shall require any Servicer to collect, create, collate or otherwise generate any information that it does not

generate in its usual course of business. The Servicers shall not be required to make copies of or ship documents to any Person unless provisions have been made for the reimbursement of the costs thereof.

SECTION 3.21 Title, Management and Disposition of REO Property.

(a) The deed or certificate of sale of any REO Property shall be taken in the name of the Trustee, or its nominee, on behalf of the Trust Fund and for the benefit of the Certificateholders. The related Servicer, on behalf of REMIC I, shall either sell any REO Property by the close of the third calendar year following the calendar year in which REMIC I acquires ownership of such REO Property for purposes of Section 860G(a)(8) of the Code or request from the Internal Revenue Service, no later than sixty (60) days before the day on which the three-year grace period would otherwise expire an extension of the three-year grace period, unless such Servicer had delivered to the Trustee an Opinion of Counsel, addressed to the Trustee and the Depositor, to the effect that the holding by REMIC I of such REO Property subsequent to three years after its acquisition will not result in the imposition on any Trust REMIC created hereunder of taxes on “prohibited transactions” thereof, as defined in Section 860F of the Code, or cause any Trust REMIC hereunder to fail to qualify as a REMIC under Federal law at any time that any Certificates are outstanding. Each Servicer shall manage, conserve, protect and operate each REO Property for the Certificateholders solely for the purpose of its prompt disposition and sale in a manner which does not cause such REO Property to fail to qualify as “foreclosure property” within the meaning of Section 860G(a)(8) of the Code or result in the receipt by any Trust REMIC created hereunder of any “income from non-permitted assets” within the meaning of Section 860F(a)(2)(B) of the Code, or any “net income from foreclosure property” which is subject to taxation under the REMIC Provisions.

(b) Each Servicer shall segregate and hold all funds collected and received in connection with the operation of any REO Property separate and apart from its own funds and general assets and shall establish and maintain with respect to REO Properties an account held in trust for the Trustee, on behalf of the Trust Fund and for the benefit of the Certificateholders (the “REO Account”), which shall be an Eligible Account. The related Servicer shall be permitted to allow the related Collection Account to serve as the REO Account, subject to the maintenance of separate ledgers for each REO Property. The related Servicer shall be entitled to retain or withdraw any interest income paid on funds deposited in the REO Account.

(c) Each Servicer shall have full power and authority, subject only to the specific requirements and prohibitions of this Agreement, to do any and all things in connection with any REO Property as are consistent with the manner in which such Servicer manages and operates similar property owned by it or any of its Affiliates, all on such terms and for such period as such Servicer deems to be in the best interests of Certificateholders. In connection therewith, the related Servicer shall deposit, or cause to be deposited in the clearing account in which it customarily deposits payments and collections on mortgage loans in connection with its mortgage loan servicing activities on

a daily basis, and in no event more than one Business Day after such Servicer’s receipt thereof, and shall thereafter deposit in the REO Account, in no event more than two Business Days after the deposit of good funds into the clearing account, all revenues received by it with respect to an REO Property and shall withdraw therefrom funds necessary for the proper operation, management and maintenance of such REO Property including, without limitation:

(i) all insurance premiums due and payable in respect of such REO Property;

(ii) all real estate taxes and assessments in respect of such REO Property that may result in the imposition of a lien thereon; and

(iii) all costs and expenses necessary to maintain such REO Property.

To the extent that amounts on deposit in the REO Account with respect to an REO Property are insufficient for the purposes set forth in clauses (i) through (iii) above with respect to such REO Property, the related Servicer shall advance from its own funds such amount as is necessary for such purposes if, but only if, such Servicer would make such advances if such Servicer owned the REO Property and if in such Servicer’s judgment, the payment of such amounts will be recoverable from the rental or sale of the REO Property.

Subject to compliance with applicable laws and regulations as shall at any time be in force, and notwithstanding the foregoing, the related Servicer, on behalf of the Trust Fund, shall not:

(i) enter into, renew or extend any New Lease with respect to any REO Property, if the New Lease by its terms will give rise to any income that does not constitute Rents from Real Property;

(ii) permit any amount to be received or accrued under any New Lease other than amounts that will constitute Rents from Real Property;

(iii) authorize or permit any construction on any REO Property, other than the completion of a building or other improvement thereon, and then only if more than ten percent of the construction of such building or other improvement was completed before default on the related Mortgage Loan became imminent, all within the meaning of Section 856(e)(4)(B) of the Code; or

(iv) allow any Person to Directly Operate any REO Property on any date more than ninety (90) days after its date of acquisition by the Trust Fund;

unless, in any such case, the related Servicer has obtained an Opinion of Counsel, provided to such Servicer and the Trustee, to the effect that such action will not cause such REO Property to fail to qualify as “foreclosure property” within the meaning of

Section 860G(a)(8) of the Code at any time that it is held by REMIC I, in which case such Servicer may take such actions as are specified in such Opinion of Counsel.

Each Servicer may contract with any Independent Contractor for the operation and management of any REO Property, provided that:

(i) the terms and conditions of any such contract shall not be inconsistent herewith;

(ii) any such contract shall require, or shall be administered to require, that the Independent Contractor pay all costs and expenses incurred in connection with the operation and management of such REO Property, including those listed above and remit all related revenues (net of such costs and expenses) to such Servicer as soon as practicable, but in no event later than thirty days following the receipt thereof by such Independent Contractor;

(iii) none of the provisions of this Section 3.21(c) relating to any such contract or to actions taken through any such Independent Contractor shall be deemed to relieve the Servicer of any of its duties and obligations to the Trustee on behalf of the Trust Fund and for the benefit of the Certificateholders with respect to the operation and management of any such REO Property; and

(iv) Such Servicer shall be obligated with respect thereto to the same extent as if it alone were performing all duties and obligations in connection with the operation and management of such REO Property.

Each Servicer shall be entitled to enter into any agreement with any Independent Contractor performing services for it related to its duties and obligations hereunder for indemnification of such Servicer by such Independent Contractor, and nothing in this Agreement shall be deemed to limit or modify such indemnification. The related Servicer shall be solely liable for all fees owed by it to any such Independent Contractor, irrespective of whether such Servicer’s compensation pursuant to Section 3.15 of this Agreement is sufficient to pay such fees. Any such agreement shall include a provision that such agreement may be immediately terminated by the Trustee or any other successor Servicer (including the Master Servicer) without fee, in the event the related Servicer shall for any reason, no longer be the Servicer of the Mortgage Loans (including termination due to a Servicer Event of Default).

(d) In addition to the withdrawals permitted under Section 3.21(c) of this Agreement, each Servicer may from time to time make withdrawals from the related REO Account for any REO Property: (i) to pay itself unpaid Servicing Fees in respect of the related Mortgage Loan; and (ii) to reimburse itself or any Sub-Servicer for unreimbursed Servicing Advances and Advances made in respect of such REO Property or the related Mortgage Loan. On the Servicer Remittance Date, the related Servicer shall withdraw from each REO Account maintained by it and deposit into the Distribution Account in accordance with Section 3.08(e)(ii) of this Agreement, for distribution on the related Distribution Date in accordance with Section 5.01 of this Agreement, the income

from the related REO Property received during the prior calendar month, net of any withdrawals made pursuant to Section 3.21(c) of this Agreement or this Section 3.21(d).

(e) Subject to the time constraints set forth in Section 3.21(a) of this Agreement, each REO Disposition shall be carried out by the related Servicer at such price and upon such terms and conditions as such Servicer shall deem necessary or advisable, as shall be normal and usual in accordance with Accepted Servicing Practices.

(f) The proceeds from the REO Disposition, net of any amount required by law to be remitted to the Mortgagor under the related Mortgage Loan and net of any payment or reimbursement to the related Servicer as provided above, shall be deposited in the Distribution Account in accordance with Section 3.08(e)(ii) of this Agreement on the Servicer Remittance Date in the month following the receipt thereof for distribution on the related Distribution Date in accordance with Section 5.01 of this Agreement. Any REO Disposition shall be for cash only (unless changes in the REMIC Provisions made subsequent to the Startup Day allow a sale for other consideration).

(g) Each Servicer shall file information returns (and shall provide a certification of a Servicing Officer to the Master Servicer that such filings have been made) with respect to the receipt of mortgage interest received in a trade or business, reports of foreclosures and abandonments of any Mortgaged Property and cancellation of indebtedness income with respect to any Mortgaged Property as required by Sections 6050H, 6050J and 6050P of the Code, respectively. Such reports shall be in form and substance sufficient to meet the reporting requirements imposed by such Sections 6050H, 6050J and 6050P of the Code.

SECTION 3.22 Obligations of Each Servicer in Respect of Prepayment Interest Shortfalls; Relief Act Interest Shortfalls.

Each Servicer shall deliver to the Securities Administrator for deposit into the Distribution Account on or before 12:00 noon New York time on the Servicer Remittance Date from its own funds an amount equal to the lesser of (i) the aggregate amount of the Prepayment Interest Shortfalls attributable to Principal Prepayments in full on the Mortgage Loans for the related Distribution Date resulting solely from voluntary Principal Prepayments received by the related Servicer during the portion of the Prepayment Period occurring from (i) with respect to Xxxxx Fargo, the 14^th day of the month preceding the month in which the related Distribution Date occurs and ending on the last day of the month preceding the month in which the related Distribution Date occurs and (ii) with respect to Ocwen, the 16^th day of the month preceding the month in which the related Distribution Date occurs and ending on the last day of the month preceding the month in which the related Distribution Date occurs and (ii) the aggregate amount of the related Servicing Fees payable to the related Servicer on such Distribution Date with respect to the related Mortgage Loans. The Servicers shall not have the right to reimbursement for any amounts remitted to the Securities Administrator in respect of this Section 3.22. The Servicers shall not be obligated to pay the amounts set forth in this Section 3.22 with respect to shortfalls resulting from the application of the Relief Act.

SECTION 3.23 Obligations of Each Servicer in Respect of Mortgage Rates and Monthly Payments.

In the event that a shortfall in any collection on or liability with respect to any Mortgage Loan results from or is attributable to adjustments to Mortgage Rates, Monthly Payments or Scheduled Principal Balances that were made by the related Servicer in a manner not consistent with the terms of the related Mortgage Note and this Agreement, such Servicer, upon discovery or receipt of notice thereof, immediately shall deliver to the Securities Administrator for deposit in the Distribution Account from its own funds the amount of any such shortfall and shall indemnify and hold harmless the Trust Fund, the Trustee, the Securities Administrator, the Master Servicer, the Depositor and any successor Servicer in respect of any such liability. Such indemnities shall survive the termination or discharge of this Agreement. Notwithstanding the foregoing, this Section 3.23 shall not limit the ability of the related Servicer to seek recovery of any such amounts from the related Mortgagor under the terms of the related Mortgage Note and Mortgage, to the extent permitted by applicable law.

SECTION 3.24

Reserve Fund.

(a) No later than the Closing Date, the Securities Administrator shall establish and maintain a separate, segregated trust account entitled, “Reserve Fund, Xxxxx Fargo Bank, National Association, in trust for the registered holders of ACE Securities Corp. Home Equity Loan Trust, Series 2005-SD3, Asset Backed Pass-Through Certificates.” On the Closing Date, the Depositor will deposit, or cause to be deposited, into the Reserve Fund $1,000.

(b) On each Distribution Date, the Securities Administrator shall deposit into the Reserve Fund the amounts described in clause sixth of Section 5.01(b)(5) of this Agreement, rather than distributing such amounts to the Class CE-1 Certificateholders, and in clause seventh of Section 5.01(b)(5) of this Agreement. On each such Distribution Date, the Securities Administrator shall hold all such amounts for the benefit of the Holders of the Class A, Mezzanine and Class B-1 Certificates and will distribute such amounts to the Holders of the Class A, Mezzanine and Class B-1 Certificates, in the amounts and priorities set forth in Section 5.01(b) of this Agreement. If no Net WAC Rate Carryover Amounts are payable on a Distribution Date, the Securities Administrator shall deposit, into the Reserve Fund on behalf of the Class CE-1 Certificateholders, from amounts otherwise distributable to the Class CE-1 Certificateholders, an amount such that when added to other amounts already on deposit in the Reserve Fund, the aggregate amount on deposit therein is equal to $1,000.

(c) For federal and state income tax purposes, the Class CE-1 Certificateholders will be deemed to be the owners of the Reserve Fund and all amounts deposited into the Reserve Fund (other than the initial deposit therein of $1,000 and any amounts paid to the Reserve Fund shall be treated as amounts distributed by REMIC II to the Holders of the Class CE-1 Certificates. Upon the termination of the Trust Fund, or the payment in full of the Class A, Mezzanine and Class B-1 Certificates, all amounts remaining on deposit in the Reserve Fund will be released by the Trust Fund and

distributed to the Class CE-1 Certificateholders or their designees. The Reserve Fund will be part of the Trust Fund but not part of any REMIC and any payments to the Holders of the Class A, Mezzanine or Class B-1 Certificates of Net WAC Rate Carryover Amounts will not be payments with respect to a “regular interest” in a REMIC within the meaning of Code Section 860(G)(a)(1).

(d) By accepting a Class CE-1 Certificate, each Class CE-1 Certificateholder hereby agrees that the Securities Administrator will deposit into the Reserve Fund the amounts described above on each Distribution Date rather than distributing such amounts to the Class CE-1 Certificateholders. By accepting a Class CE-1 Certificate, each Class CE-1 Certificateholder further agrees that its agreement to such action by the Securities Administrator is given for good and valuable consideration, the receipt and sufficiency of which is acknowledged by such acceptance.

(e) At the direction of the Holders of a majority in Percentage Interest in the Class CE-1 Certificates, the Securities Administrator shall direct any depository institution maintaining the Reserve Fund to invest the funds in such account in one or more Permitted Investments bearing interest or sold at a discount, and maturing, unless payable on demand, (i) no later than the Business Day immediately preceding the date on which such funds are required to be withdrawn from such account pursuant to this Agreement, if a Person other than the Securities Administrator or an Affiliate manages or advises such investment, and (ii) no later than the date on which such funds are required to be withdrawn from such account pursuant to this Agreement, if the Securities Administrator or an Affiliate manages or advises such investment. All income and gain earned upon such investment shall be deposited into the Reserve Fund. In no event shall the Securities Administrator be liable for any investments made pursuant to this clause (e). If the Holders of a majority in Percentage Interest in the Class CE-1 Certificates fail to provide investment instructions, funds on deposit in the Reserve Fund shall be held uninvested by the Securities Administrator without liability for interest or compensation.

(f) For federal tax return and information reporting, the right of the Class A Certificateholders, the Mezzanine Certificateholders and the Class B-1 Certificateholders to receive payments from the Reserve Fund in respect of any Net WAC Rate Carryover Amount shall be assigned a value of $125,758 with respect to the Certificates covered by the Swap Agreement.

SECTION 3.25

Advance Facility.

(a) Notwithstanding anything to the contrary contained herein, (i) each Servicer is hereby authorized to enter into an advance facility (“Advance Facility”) but no more than two Advance Facilities without the prior written consent of the Trustee, which consent shall not be unreasonably withheld, under which (A) such Servicer sells, assigns or pledges to an advancing person (an “Advance Financing Person”) its rights under this Agreement to be reimbursed for any P&I Advances or Servicing Advances and/or (B) an Advance Financing Person agrees to finance some or all P&I Advances or Servicing Advances required to be made by such Servicer pursuant to this Agreement and (ii) each Servicer is hereby authorized to assign its rights to the Servicing Fee (which

rights shall terminate upon the resignation, termination or removal of such Servicer pursuant to the terms of this Agreement); it being understood that neither the Trust Fund nor any party hereto shall have a right or claim (including without limitation any right of offset) to any amounts for reimbursement of P&I Advances or Servicing Advances so assigned or to the portion of the Servicing Fee so assigned. Subject to the provisions of the first sentence of this Section 3.25(a), no consent of the Depositor, Trustee, Master Servicer, Certificateholders or any other party is required before the related Servicer may enter into an Advance Facility, but such Servicer shall provide notice to the Depositor, Master Servicer and the Trustee of the existence of any such Advance Facility promptly upon the consummation thereof stating (a) the identity of the Advance Financing Person and (b) the identity of any Person (“Servicer’s Assignee”) who has the right to receive amounts in reimbursement of previously xxxxxxxxxxxx X&X Advances or Servicing Advances. Notwithstanding the existence of any Advance Facility under which an advancing person agrees to finance P&I Advances and/or Servicing Advances on the related Servicer’s behalf, such Servicer shall remain obligated pursuant to this Agreement to make P&I Advances and Servicing Advances pursuant to and as required by this Agreement, and shall not be relieved of such obligations by virtue of such Advance Facility.

(b) Reimbursement amounts (“Advance Reimbursement Amounts”) shall consist solely of amounts in respect of P&I Advances and/or Servicing Advances made with respect to the Mortgage Loans for which the related Servicer would be permitted to reimburse itself in accordance with this Agreement, assuming such Servicer had made the related P&I Advance(s) and/or Servicing Advance(s).

(c) Each Servicer shall maintain and provide to any successor Servicer (with, upon request, a copy to the Trustee) a detailed accounting on a loan-by-loan basis as to amounts advanced by, pledged or assigned to, and reimbursed to any advancing person. The successor Servicer shall be entitled to rely on any such information provided by the predecessor Servicer, and the successor Servicer shall not be liable for any errors in such information.

(d) Reimbursement amounts distributed with respect to each Mortgage Loan shall be allocated to outstanding xxxxxxxxxxxx X&X Advances or Servicing Advances (as the case may be) made with respect to that Mortgage Loan on a “first-in, first out” (FIFO) basis. The documentation establishing any Advance Facility shall require the related Servicer to provide to the related advancing person or its designee loan-by-loan information with respect to each such reimbursement amount distributed to such advancing person or Advance Facility trustee on each Distribution Date, to enable the advancing person or Advance Facility trustee to make the FIFO allocation of each such reimbursement amount with respect to each Mortgage Loan. The related Servicer shall remain entitled to be reimbursed by the advancing person or Advance Facility trustee for all P&I Advances and Servicing Advances funded by the related Servicer to the extent the related rights to be reimbursed therefor have not been sold, assigned or pledged to an advancing person.

(e) Any amendment to this Section 3.25 or to any other provision of this Agreement that may be necessary or appropriate to effect the terms of an Advance Facility as described generally in this Section 3.25, including amendments to add provisions relating to a successor Servicer, may be entered into by the Trustee, the Depositor and the related Servicer without the consent of any Certificateholder, notwithstanding anything to the contrary in this Agreement, provided, that the Trustee has been provided an Opinion of Counsel that such amendment is authorized hereunder and has no material adverse effect on the Certificateholders, which opinion shall be an expense of the party requesting such opinion but in any case shall not be an expense of the Trustee or the Trust Fund; provided, further, that the amendment shall not be deemed to adversely affect in any material respect the interests of the Certificateholders if the Person requesting the amendment obtains a letter from each Rating Agency (instead of obtaining an Opinion of Counsel to such effect) stating that the amendment would not result in the downgrading or withdrawal of the respective ratings then assigned to the Certificates; it being understood and agreed that any such rating letter in and of itself will not represent a determination as to the materiality of any such amendment and will represent a determination only as to the credit issues affecting any such rating. Prior to entering into an Advance Facility, the related Servicer shall notify the lender under such facility in writing that: (a) the P&I Advances and/or Servicing Advances financed by and/or pledged to the lender are obligations owed to such Servicer on a non-recourse basis payable only from the cash flows and proceeds received under this Agreement for reimbursement of P&I Advances and/or Servicing Advances only to the extent provided herein, and neither the Master Servicer, the Securities Administrator, the Trustee nor the Trust are otherwise obligated or liable to repay any P&I Advances and/or Servicing Advances financed by the lender; (b) such Servicer will be responsible for remitting to the lender the applicable amounts collected by it as Servicing Fees and as reimbursement for P&I Advances and/or Servicing Advances funded by the lender, as applicable, subject to the restrictions and priorities created in this Agreement; and (c) neither the Master Servicer, the Securities Administrator nor the Trustee shall have any responsibility to calculate any amount payable under an Advance Facility or to track or monitor the administration of the financing arrangement between such Servicer and the lender or the payment of any amount under an Advance Facility.

(f) The related Servicer shall indemnify the Master Servicer, the Securities Administrator, the Trustee and the Trust Fund for any cost, liability or expense relating to the Advance Facility including, without limitation, a claim, pending or threatened, by an Advance Financing Person.

SECTION 3.26

The Servicer’s Indemnification Obligation.

Each Servicer agrees to indemnify the Trustee, the Master Servicer and the Securities Administrator, from, and hold the Trustee, Master Servicer and the Securities Administrator harmless against, any loss, liability or expense (including reasonable attorney’s fees and expenses) incurred by any such Person by reason of such Servicer’s willful misfeasance, bad faith or gross negligence in the performance of its duties under this Agreement or by reason of such Servicer’s reckless disregard of its obligations and duties under this Agreement. Such indemnity shall survive the termination or discharge

of this Agreement and the resignation or removal of the related Servicer, the Trustee, the Master Servicer and the Securities Administrator. Any payment hereunder made by the related Servicer to any such Person shall be from such Servicer’s own funds, without reimbursement from REMIC I therefor.

(a) The Master Servicer shall be responsible for monitoring the compliance by Ocwen and Xxxxx Fargo with their duties under this Agreement and WAMU with its duties under the Servicing Agreement. In the review of the related Servicer’s activities, the Master Servicer may rely upon an officer’s certificate of the related Servicer with regard to such Servicer’s compliance with the terms of this Agreement or the Servicing Agreement, as applicable. In the event that the Master Servicer, in its judgment, determines that a Servicer should be terminated in accordance with the terms hereof or the terms of the Servicing Agreement or that a notice should be sent pursuant to the terms hereof or the terms of the Servicing Agreement with respect to the occurrence of an event that, unless cured, would constitute a Servicer Event of Default, or an event of default under the Servicing Agreement, the Master Servicer shall

notify the related Servicer, 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 Ocwen under this Agreement and WAMU under the Servicing Agreement.

In the event that Xxxxx Fargo fails to perform its obligations in accordance with this Agreement the Trustee shall, subject to this Section and Article VIII, terminate the rights and obligations of Xxxxx Fargo hereunder in accordance with the provisions of Article VIII of this Agreement. In the event that WAMU fails to perform its obligations in accordance with the Servicing Agreement, the Master Servicer shall terminate the rights and obligations of such Servicer as servicer in accordance with the Servicing Agreement. Such enforcement, including, without limitation, the legal prosecution of claims 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 Mortgage Loans. Except as set forth below, the Master Servicer shall pay the costs of such enforcement at its own expense, provided that the Master Servicer and the Trustee shall not be required to prosecute or defend any legal action except to the extent that the Master Servicer or the Trustee, as applicable, shall have received reasonable indemnity for its costs and expenses in pursuing such action. To the extent that such costs and expenses are not indemnified by Ocwen, Xxxxx Fargo or WAMU hereunder or under the Servicing Agreement, then the Trustee and the Master Servicer shall be indemnified for such costs and expenses out of the Trust Fund.

(c) The Master Servicer or, in the case of Xxxxx Fargo, the Trustee, shall be entitled to be reimbursed by the related Servicer (or from amounts on deposit in the Distribution Account if the related Servicer is unable to fulfill its obligations hereunder or under the Servicing Agreement) for all reasonable out-of-pocket or third party costs associated with the transfer of servicing from the predecessor Servicer (or if the predecessor Servicer is the Master Servicer, from the related Servicer immediately preceding the Master Servicer), including without limitation, any reasonable out-of-pocket or third party costs or expenses associated with the complete transfer of all servicing data and the completion, correction or manipulation of such servicing data as may be required by the Master Servicer or, in the case of Xxxxx Fargo, the Trustee to correct any errors or insufficiencies in the servicing data or otherwise to enable a successor servicer (which may be the Master Servicer except with respect to the Xxxxx Fargo Mortgage Loans) to service the related Mortgage Loans properly and effectively, upon presentation of reasonable documentation of such costs and expenses.

(d) The Master Servicer shall require the Servicers to comply with the remittance requirements and other obligations set forth in this Agreement and the Servicing Agreement, as applicable.

SECTION 4.04

Fidelity Bond.

The Master Servicer, at its expense, shall maintain in effect a blanket fidelity bond and an errors and omissions insurance policy, 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 Master Servicer shall master service the Mortgage Loans and shall have full power and authority, subject to the REMIC Provisions and the provisions of Article XI, to do any and all things that it may deem necessary or desirable in connection with the master servicing and administration of the Mortgage 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 Mortgage Loan, in each case, in accordance with the provisions of this Agreement; provided, however, that the Master Servicer shall not (and, consistent with its responsibilities under Section 4.03, shall not permit a Servicer) 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 REMIC I, REMIC II or REMIC III 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 REMIC I, REMIC II or REMIC III to fail to qualify as a REMIC or result in the imposition of a tax upon REMIC I, REMIC II or REMIC III, as the case may be. The Trustee shall furnish the Master Servicer, upon written request from a Servicing Officer, with any powers of attorney prepared and delivered to it and reasonably acceptable to it by empowering the Master Servicer or the Servicers 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 Mortgage Loans or the Mortgaged Property, in accordance with this Agreement or the Servicing Agreement, and the Trustee shall execute and deliver such

other documents prepared and delivered to it and reasonably acceptable to it, as the Master Servicer or the related Servicer may request, to enable the Master Servicer to master service and administer the related Mortgage 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 use or misuse of any such powers of attorney or such other executed documents delivered by the Trustee pursuant to this paragraph by the Master Servicer or the Servicers and shall be indemnified by the Master Servicer or the related Servicer, as applicable, for any cost, liability or expense incurred by the Trustee in connection with such Person’s use or misuse of any such power of attorney or such other executed documents delivered by the Trustee pursuant to this paragraph). 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 9.10. 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 in the name of the Trustee, be deemed to be the agent of the Trustee.

SECTION 4.06

Due-on-Sale Clauses; Assumption Agreements.

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

SECTION 4.07 Documents, Records and Funds in Possession of Master Servicer To Be Held for Trustee.

(a) The Master Servicer shall transmit to the Trustee or the applicable Custodian such documents and instruments coming into the possession of the Master Servicer from time to time as are required by the terms hereof to be delivered to the Trustee or the applicable Custodian.

Office of Thrift Supervision or other regulatory authority, such access to be afforded without charge but only upon reasonable request in writing and during normal business hours at the offices of the Master Servicer designated by it. In fulfilling such a request the Master Servicer shall not be responsible for determining the sufficiency of such information.

Any proceeds disbursed to the Master Servicer (or disbursed to the Servicer and remitted to the Master Servicer) in respect of such policies, bonds or contracts shall be promptly deposited in the Distribution Account upon receipt, except that any amounts realized that are to be applied to the repair or restoration of the related Mortgaged Property as a condition precedent to the presentation of claims on the related Mortgage Loan to the insurer under any applicable insurance policy need not be so deposited or remitted.

SECTION 4.10 Maintenance of Primary Mortgage Insurance Policies.

(a) The Master Servicer shall not take, or permit a Servicer to take (to the extent such action is prohibited by this Agreement or the Servicing Agreement), any action that would result in noncoverage under any primary mortgage insurance policy of any loss which, but for the actions of the Master Servicer or the related Servicer, as

applicable, would have been covered thereunder. The Master Servicer shall use its best reasonable efforts to cause the Servicers to keep in force and effect (to the extent that the Mortgage Loan requires the Mortgagor to maintain such insurance), primary mortgage insurance applicable to each Mortgage Loan in accordance with the provisions of this Agreement or the Servicing Agreement. The Master Servicer shall not, and shall not permit the Servicers to, cancel or refuse to renew any primary mortgage insurance policy that is in effect at the date of the initial issuance of the Mortgage Note and is required to be kept in force hereunder except in accordance with the provisions of this Agreement or the Servicing Agreement.

(b) The Master Servicer agrees to cause the Servicers to present, on behalf of the Trustee and the Certificateholders, claims to the insurer under any primary mortgage insurance policies and, in this regard, to take such reasonable action as shall be necessary to permit recovery under any primary mortgage insurance policies respecting defaulted Mortgage Loans.

The Master Servicer shall promptly deliver or cause to be delivered to the Trustee or the applicable Custodian, upon the execution or receipt thereof the originals of any primary mortgage insurance policies, any certificates of renewal, and such other documents or instruments that constitute Mortgage Loan Documents that come into the possession of the Master Servicer from time to time.

Further, the Master Servicer shall cause the Servicers to sell any REO Property prior to three years after the end of the calendar year of its acquisition by REMIC I unless (i) the Trustee shall have been supplied by the related Servicer with an Opinion of Counsel to the effect that the holding by the Trust Fund of such REO Property subsequent to such three-year period will not result in the imposition of taxes on “prohibited transactions” of any REMIC hereunder as defined in Section 860F of the Code or cause any REMIC hereunder to fail to qualify as a REMIC at any time that any Certificates are outstanding, in which case the Trust Fund may continue to hold such Mortgaged Property (subject to any conditions contained in such Opinion of Counsel) or (ii) the related Servicer shall have applied for, prior to the expiration of such three-year period, an extension of such three-year period in the manner contemplated by Section 856(e)(3) of the Code, in which case the three-year period shall be extended by the applicable extension period. The Master Servicer shall cause the related Servicer to protect and conserve, such REO Property in the manner and to the extent required by this Agreement or the Servicing Agreement, as applicable, in accordance with the REMIC Provisions and in a manner that does not result in a tax on “net income from foreclosure property” or cause such REO Property to fail to qualify as “foreclosure property” within the meaning of Section 860G(a)(8) of the Code.

(b) Copies of such statements shall be provided to any Certificateholder upon request, by the Master Servicer or by the Trustee at the Master Servicer’s expense if the Master Servicer failed to provide such copies (unless (i) the Master Servicer shall have failed to provide the Trustee with such statement or (ii) the Trustee shall be unaware of the Master Servicer’s failure to provide such statement).

SECTION 4.16 Annual Independent Accountant’s Servicing Report.

If the Master Servicer has, during the course of any calendar year, directly serviced any of the Mortgage Loans, then the Master Servicer at its expense shall cause a nationally recognized firm of independent certified public accountants to furnish a statement to the Trustee, the Rating Agencies and the Seller on or before March 15 of each year commencing on March 15, 2006, to the effect that, with respect to the most recently ended fiscal year, such firm has examined certain records and documents relating to the Master Servicer’s performance of its servicing obligations under this Agreement and pooling and servicing and trust agreements in material respects similar to this Agreement and to each other and that, on the basis of such examination conducted substantially in compliance with the audit program for mortgages serviced for Xxxxxxx Mac or the Uniform Single Attestation Program for Mortgage Bankers, such firm is of the opinion that the Master Servicer’s activities have been conducted in compliance with this Agreement, or that such examination has disclosed no material items of noncompliance except for (i) such exceptions as such firm believes to be immaterial, (ii) such other exceptions as are set forth in such statement and (iii) such exceptions that the Uniform Single Attestation Program for Mortgage Bankers or the Audit Program for Mortgages Serviced by Xxxxxxx Mac requires it to report.

If such report discloses exceptions that are material, the Master Servicer shall advise the Trustee whether such exceptions have been or are susceptible of cure, and will take prompt action to do so.

If the related 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 its position.

Each brokerage firm shall be responsible for disbursing funds to the Certificate Owners that it represents. None of the Trustee, the Depositor, the Servicers, the Securities Administrator or the Master Servicer shall have any responsibility therefor except as otherwise provided by this Agreement or applicable law.

(h) The rights of the Certificateholders to receive distributions in respect of the Certificates, and all interests of the Certificateholders in such distributions, shall be as set forth in this Agreement.

Any funds not distributed to any Holder or Holders of Certificates of such Class 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 by the Securities Administrator 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 5.01(i) 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 but shall continue to hold any remaining funds for the benefit of non-tendering Certificateholders. The costs and expenses of maintaining the funds in trust and of contacting such Certificateholders shall be paid out of the assets remaining in such trust fund. 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) on the final Distribution Date for final payment thereof in accordance with this Section 5.01(i). Any such amounts held in trust by the Securities Administrator shall be held uninvested in an Eligible Account.

(j) Notwithstanding anything to the contrary herein, (i) in no event shall the Certificate Principal Balance of a Class A Certificate, Mezzanine Certificate or a Class B-1 Certificate be reduced more than once in respect of any particular amount both (a) allocated to such Certificate in respect of Realized Losses pursuant to Section 5.04 of this Agreement and (b) distributed to the Holder of such Certificate in reduction of the Certificate Principal Balance thereof pursuant to this Section 5.01 from Net Monthly Excess Cashflow and (ii) in no event shall the Uncertificated Balance of a REMIC Regular Interest be reduced more than once in respect of any particular amount both (a) allocated to such REMIC Regular Interest in respect of Realized Losses pursuant to Section 5.04 of this Agreement and (b) distributed on such REMIC Regular Interest in reduction of the Uncertificated Balance thereof pursuant to this Section 5.01.

SECTION 5.03

Servicer Reports; P&I Advances.

(a) On or before 12:00 noon New York time on the 18th calendar day of each month, and if the 18th calendar day is not a Business Day, the immediately following Business Day, the related Servicer shall deliver to the Master Servicer and the Securities Administrator by telecopy or electronic mail (or by such other means as such Servicer, the Master Servicer and the Securities Administrator may agree from time to time) a remittance report containing such information with respect to the related Mortgage Loans and the related Distribution Date as is reasonably available to such Servicer as the Master Servicer or the Securities Administrator may reasonably require so as to enable the Master Servicer to master service the Mortgage Loans and oversee the servicing by such Servicer and the Securities Administrator to fulfill its obligations hereunder with respect to securities and tax reporting. Any report delivered by a Servicer pursuant to this Section 5.03(a) shall include the amount collected by such Servicer in respect of Arrearages and principal due on the Mortgage Loans prior to the Cut-off Date.

(b) The amount of P&I Advances to be made by the related Servicer on any Distribution Date shall equal, subject to Section 5.03(d), (i) with respect to the Mortgage Loans other than the Simple Interest Mortgage Loans, the aggregate amount of Monthly Payments (net of the related Servicing Fees), due during the related Due Period in respect of the Mortgage Loans, which Monthly Payments were delinquent as of the close of business on the related Determination Date, (ii) with respect to the Simple Interest Mortgage Loans, thirty (30) days’ interest (net of the related Servicing Fees) on each such Simple Interest Mortgage Loan for which the Monthly Payment was due during the related Due Period which Monthly Payments were delinquent as of the close of business on the related Determination Date and (iii) with respect to each REO Property which was acquired during or prior to the related Prepayment Period and as to which an REO Disposition did not occur during the related Prepayment Period, an amount equal to the excess, if any, of the REO Imputed Interest on such REO Property for the most recently ended calendar month, over the net income from such REO Property deposited in the Collection Account pursuant to Section 3.21 of this Agreement for distribution on such Distribution Date; provided, however, no Servicer shall be required to make P&I Advances with respect to any Monthly Payments due on a Mortgage Loan prior to the Cut-off Date, any Relief Act Interest Shortfalls, or with respect to Prepayment Interest

Shortfalls in excess of its obligations under Section 3.22 of this Agreement. For purposes of the preceding sentence, the Monthly Payment on each Balloon Mortgage Loan with a delinquent Balloon Payment is equal to the assumed monthly payment that would have been due on the related Due Date based on the original principal amortization schedule for such Balloon Mortgage Loan. Notwithstanding the generality of the foregoing, for purposes of a Servicer’s determination of whether or not a P&I Advance is required to be made on a Mortgage Loan for which the Mortgagor has failed to make one or more Monthly Payments due on such Mortgage Loan on or prior to the Cut-off Date, any payment in an amount equal to a Monthly Payment received by the related Servicer during the Due Period relating to such Servicer Remittance Date shall be deemed to be the Monthly Payment due during such Due Period and the related Servicer shall not be required to make a P&I Advance with respect to such Mortgage Loan. In addition, no portion of such Monthly Payment received on such Mortgage Loan will constitute the receipt of an Arrearage with respect to such Mortgage Loan unless all Monthly Payments required to be made on such Mortgage Loan for all prior Due Periods occurring subsequent to the Cut-off Date have been received by the related Servicer.

By 12:00 noon New York time on the Servicer Remittance Date, each Servicer shall remit in immediately available funds to the Securities Administrator for deposit in the Distribution Account an amount equal to the aggregate amount of P&I Advances, if any, to be made in respect of the Mortgage Loans serviced by such Servicer for the related Distribution Date either (i) from its own funds or (ii) from the related Collection Account, to the extent of any Amounts Held For Future Distribution on deposit therein (in which case it will cause to be made an appropriate entry in the records of the related Collection Account that Amounts Held For Future Distribution have been, as permitted by this Section 5.03, used by the related Servicer in discharge of any such P&I Advance) or (iii) in the form of any combination of (i) and (ii) aggregating the total amount of P&I Advances to be made by the related Servicer with respect to the Mortgage Loans. In addition, the related Servicer shall have the right to reimburse itself for any outstanding P&I Advance made from its own funds from Amounts Held for Future Distribution. Any Amounts Held For Future Distribution used by the related Servicer to make P&I Advances or to reimburse itself for outstanding P&I Advances shall be appropriately reflected in such Servicer’s records and replaced by such Servicer by deposit in the related Collection Account no later than the close of business on the Servicer Remittance Date immediately following the Due Period or Prepayment Period for which such amounts relate. The Securities Administrator will notify the related Servicer and the Master Servicer by the close of business on the Business Day prior to the Distribution Date in the event that the amount remitted by the related Servicer to the Securities Administrator on such date is less than the P&I Advances required to be made by such Servicer for the related Distribution Date.

(c) The obligation of each Servicer to make such P&I Advances with respect to the Mortgage Loans serviced by such Servicer is mandatory, notwithstanding any other provision of this Agreement but subject to (d) below, and, with respect to any Mortgage Loan or REO Property, shall continue until a Final Recovery Determination in connection therewith or the removal thereof from the Trust Fund pursuant to any applicable provision of this Agreement, except as otherwise provided in this Section.

(d) Notwithstanding anything herein to the contrary, no P&I Advance or Servicing Advance shall be required to be made hereunder by any Servicer if such P&I Advance or Servicing Advance would, if made, constitute a Nonrecoverable P&I Advance or Nonrecoverable Servicing Advance, respectively. The determination by the related Servicer that it has made a Nonrecoverable P&I Advance or a Nonrecoverable Servicing Advance or that any proposed P&I Advance or Servicing Advance, if made, would constitute a Nonrecoverable P&I Advance or Nonrecoverable Servicing Advance, respectively, shall be evidenced by a certification of a Servicing Officer delivered to the Master Servicer.

(e) Subject to and in accordance with the provisions of Article VIII of this Agreement, in the event a Servicer fails to make any required P&I Advance, then the Master Servicer (in its capacity as successor servicer) or any other successor Servicer shall be required to make such P&I Advance on the Distribution Date on which the related Servicer was required to make such Advance, subject to its determination of recoverability. Subject to and in accordance with the provisions of Article VIII of this Agreement, in the event Xxxxx Fargo fails to make any required P&I Advance, then the Trustee or a successor servicer shall be required to make such P&I Advance on the Distribution Date on which Xxxxx Fargo was required to make such Advance, subject to its determination of recoverability. In addition, in the event that WAMU fails to make a required P&I Advance under the Servicing Agreement, the Master Servicer (in its capacity as successor Servicer) will be required to make such P&I Advance on the Distribution Date on which such Servicer was required to make such P&I Advance, subject to its determination of recoverability.

SECTION 5.04

Allocation of Realized Losses.

(a) On or before 12:00 noon New York time on the 18th calendar day of each month, and if the 18th calendar day is not a Business Day, the immediately following Business Day, the related Servicer shall determine as to each Mortgage Loan serviced by such Servicer and any related REO Property and include in the monthly remittance report provided to the Master Servicer and the Securities Administrator (substantially in the form of Schedule 4 hereto), or in the additional information provided by WAMU at the request of the Master Servicer in accordance with Section 4.20 hereto, such information as is reasonably available to the related Servicer, as the Master Servicer or the Securities Administrator may reasonably require so as to enable the Master Servicer to master service the Mortgage Loans and oversee the servicing by the related Servicer and the Securities Administrator to fulfill its obligations hereunder with respect to securities and tax reporting, which shall include, but not be limited to: (i) the total amount of Realized Losses, if any, incurred in connection with any Final Recovery Determinations made during the related Prepayment Period; and (ii) the respective portions of such Realized Losses allocable to interest and allocable to principal. Prior to each Determination Date, the Servicers shall also determine as to each Mortgage Loan: (i) the total amount of Realized Losses, if any, incurred in connection with any Deficient Valuations made during the related Prepayment Period; and (ii) the total amount of Realized Losses, if any, incurred in connection with Debt Service Reductions in respect of Monthly Payments due during the related Due Period.

(b) All Realized Losses on the Mortgage Loans allocated to any REMIC I Regular Interest pursuant to Section 5.04(c) of this Agreement shall be allocated by the Securities Administrator on each Distribution Date as follows: first, to Net Monthly Excess Cashflow; second, to the Class CE-1 Certificates and to Net Swap Payments received from the Swap Provider under the Swap Agreement for that purpose; third, to the Class B-1 Certificates, until the Certificate Principal Balance of the Class B-1 Certificates has been reduced to zero, fourth, to the Class M-5 Certificates, until the Certificate Principal Balance of the Class M-5 Certificates has been reduced to zero; fifth, to the Class M-4 Certificates, until the Certificate Principal Balance of the Class M-4 Certificates has been reduced to zero; sixth, to the Class M-3 Certificates, until the Certificate Principal Balance of the Class M-3 Certificates has been reduced to zero; seventh, to the Class M-2 Certificates, until the Certificate Principal Balance of the Class M-2 Certificates has been reduced to zero; and eighth, to the Class M-1 Certificates, until the Certificate Principal Balance of the Class M-1 Certificates has been reduced to zero. All Realized Losses to be allocated to the Certificate Principal Balances of all Classes on any Distribution Date shall be so allocated after the actual distributions to be made on such date as provided above. All references above to the Certificate Principal Balance of any Class of Certificates shall be to the Certificate Principal Balance of such Class immediately prior to the relevant Distribution Date, before reduction thereof by any Realized Losses, in each case to be allocated to such Class of Certificates, on such Distribution Date.

Any allocation of Realized Losses to a Mezzanine Certificate on any Distribution Date shall be made by reducing the Certificate Principal Balance thereof by the amount so allocated; any allocation of Realized Losses to a Class CE-1 Certificates shall be made by reducing the amount otherwise payable in respect thereof pursuant to clause tenth of Section

5.01(b)(5). No allocations of any Realized Losses shall be made to the Certificate Principal Balances of the Class A Certificates.

As used herein, an allocation of a Realized Loss on a “pro rata basis” among two or more specified Classes of Certificates means an allocation on a pro rata basis, among the various Classes so specified, to each such Class of Certificates on the basis of their then outstanding Certificate Principal Balances prior to giving effect to distributions to be made on such Distribution Date. All Realized Losses and all other losses allocated to a Class of Certificates hereunder will be allocated among the, Certificates of such Class in proportion to the Percentage Interests evidenced thereby.

In addition, in the event that a Servicer receives any Subsequent Recoveries, such Servicer shall deposit such funds into the related Collection Account pursuant to Section 3.08 of this Agreement or into the Custodial Account pursuant to the Servicing Agreement. If, after taking into account such Subsequent Recoveries the amount of a Realized Loss is reduced, the amount of such Subsequent Recoveries will be applied to increase the Certificate Principal Balance of the Class B-1 Certificates or Mezzanine Certificates with the highest payment priority to which Realized Losses have been allocated, but not by more than the amount of Realized Losses previously allocated to that Class of Certificates pursuant to this Section 5.04 and not previously reimbursed to such Class of Certificates with Net Monthly Excess Cashflow pursuant to clause third of Section 5.01(b)(5) of this Agreement. The amount of any remaining Subsequent Recoveries will be applied to sequentially increase the Certificate Principal Balance of the Class B-1 Certificates or Mezzanine Certificates, beginning with the Class of such Certificates with the next highest payment priority, up to the amount of such Realized Losses previously allocated to such Class of Certificates pursuant to this Section 5.04 and not previously reimbursed to such Class of Certificates with Net Monthly Excess Cashflow pursuant to clause third of Section 5.01(b)(5). 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. Any such increases shall be applied to the Certificate Principal Balance of each Class B-1 Certificate or Mezzanine Certificate of such Class in accordance with its respective Percentage Interest.

(i) All Realized Losses on the Mortgage Loans shall be allocated on each Distribution Date first, to REMIC I Regular Interest A-I until the Uncertificated Balance of such REMIC I Regular Interest has been reduced to zero and second, to REMIC I Regular Interest I-1-A through REMIC I Regular Interest I-49-B, starting with the lowest numerical denomination until such REMIC I Regular Interest has been reduced to zero, provided that, for REMIC I Regular Interests with the same numerical denomination, such Realized Losses shall be allocated pro rata between such REMIC I Regular Interests.

(ii) All Realized Losses on the Mortgage Loans shall be allocated by the Trustee, based solely on the instructions of the Securities Administrator, on each Distribution Date to the following REMIC II Regular Interests in the specified percentages, as follows: first, to Uncertificated Interest payable to the REMIC II Regular Interest AA and REMIC II Regular Interest ZZ up to an aggregate amount equal to the REMIC II Interest Loss Allocation Amount, 98.00% and 2.00%, respectively; second, to the Uncertificated Balances of the REMIC II Regular Interest AA and REMIC II Regular Interest ZZ up to an aggregate amount equal to the

REMIC II Principal Loss Allocation Amount, 98.00% and 2.00%, respectively; third, to the Uncertificated Balances of REMIC II Regular Interest AA, REMIC II Regular Interest B-1 and REMIC II Regular Interest ZZ, 98.00%, 1.00% and 1.00%, respectively, until the Uncertificated Balance of REMIC II Regular Interest B-1 has been reduced to zero; fourth, to the Uncertificated Balances of REMIC II Regular Interest AA, REMIC II Regular Interest M-5 and REMIC II Regular Interest ZZ, 98.00%, 1.00% and 1.00%, respectively, until the Uncertificated Balance of REMIC II Regular Interest M-5 has been reduced to zero; fifth, to the Uncertificated Balances of REMIC II Regular Interest AA, REMIC II Regular Interest M-4 and REMIC II Regular Interest ZZ, 98.00%, 1.00% and 1.00%, respectively, until the Uncertificated Balance of REMIC II Regular Interest M-4 has been reduced to zero; sixth, to the Uncertificated Balances of REMIC II Regular Interest AA, REMIC II Regular Interest M-3 and REMIC II Regular Interest ZZ, 98.00%, 1.00% and 1.00%, respectively, until the Uncertificated Balance of REMIC II Regular Interest M-3 has been reduced to zero; seventh, to the Uncertificated Balances of REMIC II Regular Interest AA, REMIC II Regular Interest M-2 and REMIC II Regular Interest ZZ, 98.00%, 1.00% and 1.00%, respectively, until the Uncertificated Balance of REMIC II Regular Interest M-2 has been reduced to zero; and eighth, to the Uncertificated Balances of REMIC II Regular Interest AA, REMIC II Regular Interest M-1 and REMIC II Regular Interest ZZ, 98.00%, 1.00% and 1.00%, respectively, until the Uncertificated Balance of REMIC II Regular Interest M-1 has been reduced to zero.

SECTION 5.05

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 reasonably believes 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 5.06

Reports Filed with Securities and Exchange Commission.

The Depositor shall prepare or cause to be prepared the initial current report on Form 8-K. Within fifteen (15) days after each Distribution Date, the Securities Administrator shall, in accordance with industry standards, file with the Commission via the Electronic Data Gathering and Retrieval System (“XXXXX”), a Form 8-K (or other comparable Form containing the same or comparable information or other information mutually agreed upon) with a copy of the statement to be furnished to the Certificateholders for such Distribution Date as an exhibit thereto. Prior to January 30, 2006, the Securities Administrator shall, in accordance with industry standards, file a Form 15 Suspension Notice with respect to the Trust Fund, if applicable. Prior to (i) March 20, 2006 and (ii) unless and until a Form 15 Suspension Notice shall have been filed, prior to March 20th of each year thereafter, the Master Servicer shall provide the Securities Administrator with a Master Servicer Certification, together with a copy of the annual independent accountant’s servicing report and annual statement of compliance of the Servicers to be delivered pursuant to this Agreement or the Servicing Agreement, as applicable, and, if applicable, the annual independent accountant’s servicing report and annual statement of

compliance to be delivered by the Master Servicer pursuant to Section 4.15 and Section 4.16 of this Agreement. Prior to (i) March 31, 2006 and (ii) unless and until a Form 15 Suspension Notice shall have been filed, March 31 of each year thereafter, the Securities Administrator shall file a Form 10-K, in substance conforming to industry standards, with respect to the Trust. Such Form 10-K shall include the Master Servicer Certification and other documentation provided by the Master Servicer pursuant to the second preceding sentence. The Depositor hereby grants to the Securities Administrator a limited power of attorney to execute and file each such document on behalf of the Depositor. Such power of attorney shall continue until either the earlier of (i) receipt by the Securities Administrator from the Depositor of written termination of such power of attorney and (ii) the termination of the Trust Fund. The Depositor agrees to promptly furnish to the Securities Administrator, from time to time upon request, such further information, reports and financial statements within its control related to this Agreement, the Mortgage Loans as the Securities Administrator reasonably deems appropriate to prepare and file all necessary reports with the Commission. The Securities Administrator shall have no responsibility to file any items other than those specified in this Section 5.06; provided, however, the Securities Administrator will cooperate with the Depositor in connection with any additional filings with respect to the Trust Fund as the Depositor deems necessary under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Fees and expenses incurred by the Securities Administrator in connection with this Section 5.06 shall not be reimbursable from the Trust Fund.

SECTION 5.07

Supplemental Interest Trust.

(a) On the Closing Date, the Securities Administrator shall establish and maintain in the name of the Trustee a separate account for the benefit of the holders of the Offered Certificates and Class B-1 Certificates (the “Supplemental Interest Trust”). The Supplemental Interest Trust shall be an Eligible Account, and funds on deposit therein shall be held separate and apart from, and shall not be commingled with, any other moneys, including, without limitation, other moneys of the Trustee or of the Securities Administrator held pursuant to this Agreement.

(b) On each Distribution Date, the Securities Administrator shall deposit into the Supplemental Interest Trust amounts distributable to the Swap Provider by the Supplemental Interest Trust pursuant to Section 5.01(b)(2), (3), (4) and (5) of this Agreement. On each Distribution Date, the Securities Administrator shall distribute any such amounts to the Swap Provider pursuant to the Swap Agreement, first to pay any Net Swap Payment owed to the Swap Provider for such Distribution Date, and second to pay any Swap Termination Payment owed to the Swap Provider not due to a Swap Provider Trigger Event.

(c) On each Distribution Date, the Securities Administrator shall deposit into the Supplemental Interest Trust amounts received by it from the Swap Provider and shall distribute from the Supplemental Interest Trust an amount equal to the amount of any Net Swap Payment received from the Swap Provider under the Swap Agreement in the order of priority set forth in Section 5.01(e).

(d) The Supplemental Interest Trust constitutes an “outside reserve fund” within the meaning of Treasury Regulation § 1.860G-2(h) and is not an asset of any REMIC. The Holders of the Class CE-1 Certificates shall be the beneficial owner of the Supplemental

Interest Trust, subject to the power of the Securities Administrator to transfer amounts under this Agreement. The Securities Administrator shall keep records that accurately reflect the funds on deposit in the Supplemental Interest Trust. The Securities Administrator shall, at the written direction of the majority of the Class CE-1 Certificateholders, invest amounts on deposit in the Supplemental Interest Trust in Permitted Investments. In the absence of written direction to the Securities Administrator from the majority of the Class CE-1 Certificateholders, all funds in the Supplemental Interest Trust shall remain uninvested. On each Distribution Date, the Securities Administrator shall distribute, not in respect of any REMIC, any interest earned on the Supplemental Interest Trust to the Holders of the Class CE-1 Certificates.

(e) For federal income tax purposes, amounts paid to the Supplemental Interest Trust on each Distribution Date pursuant to Section 5.01(b)(2), (3), (4) and (5) shall first be deemed paid to the Supplemental Interest Trust in respect of the Class IO Interest to the extent of the amount distributable on such Class IO Interest on such Distribution Date, and any remaining amount shall be deemed paid to the Supplemental Interest Trust in respect of a Class IO Distribution Amount. For federal income tax purposes, the Supplemental Interest Trust will be a disregarded entity.

(f) The Securities Administrator shall treat the Holders of Certificates (other than the Class CE-1, Class CE-2 and Class R Certificates) as having entered into a notional principal contract with respect to the Holders of the Class CE-1 Certificates. Pursuant to each such notional principal contract, all Holders of Certificates (other than the Class CE-1, Class CE-2 and Class R Certificates) shall be treated as having agreed to pay, on each Distribution Date, to the Holder of the Class CE-1 Certificates an aggregate amount equal to the excess, if any, of (i) the amount payable on such Distribution Date on the REMIC III Regular Interest ownership of which is represented by such Class of Certificates over (ii) the amount payable on such Class of Certificates on such Distribution Date (such excess, a “Class IO Distribution Amount”). A Class IO Distribution Amount payable from interest collections shall be allocated pro rata among such Certificates based on the amount of interest otherwise payable to such Certificates, and a Class IO Distribution Amount payable from principal collections shall be allocated to the most subordinate Class of such Certificates with an outstanding principal balance to the extent of such balance. In addition, pursuant to such notional principal contract, the Holder of the Class CE-1 Certificates shall be treated as having agreed to pay Net WAC Rate Carryover Amounts to the Holders of the Certificates (other than the Class CE-1, Class CE-2 and Class R Certificates) in accordance with the terms of this Agreement. Any payments to such Certificates from amounts deemed received in respect of this notional principal contract shall not be payments with respect to a Regular Interest in a REMIC within the meaning of Code Section 860G(a)(1). However, any payment from the Certificates (other than the Class CE-1, Class CE-2 and Class R Certificates) of a Class IO Distribution Amount shall be treated for tax purposes as having been received by the Holders of such Certificates in respect of the REMIC III Regular Interest ownership of which is represented by such Certificates, and as having been paid by such Holders to the Supplemental Interest Trust pursuant to the notional principal contract. Thus, each Certificate (other than the Class CE-2 Certificates and Class R Certificates) shall be treated as representing not only ownership of a Regular Interest in REMIC III, but also ownership of an interest in, and obligations with respect to, a notional principal contract.

(g) For federal tax return and information reporting, the right of the holders of the Offered Certificates and Class B-1 Certificates to receive payments from the Supplemental Interest Trust shall be assigned a value of $125,758.

(h) In the event that the Swap Agreement is terminated prior to the Distribution Date in December 2009, the Seller shall use reasonable efforts to appoint a successor swap provider using any Swap Termination Payments paid by the Swap Provider. If the Seller is unable to locate a qualified successor swap provider, any such Swap Termination Payments will be remitted to the Securities Administrator for payment to the holders of the Offered Certificates and Class B-1 Certificates of amounts described in Section 5.07(c).

SECTION 5.08 Tax Treatment of Swap Payments and Swap Termination Payments.

For federal income tax purposes, each holder of an Offered Certificate or a Class B-1 Certificate is deemed to own an undivided beneficial ownership interest in a REMIC regular interest and the right to receive payments from either the Reserve Fund or the Supplemental Interest Trust in respect of any Net WAC Rate Carryover Amounts or the obligation to make payments to the Supplemental Interest Trust. For federal income tax purposes, the Securities Administrator will account for payments to each Offered Certificate and Class B-1 Certificate as follows: each Offered Certificate and Class B-1 Certificate will be treated as receiving their entire payment from REMIC III (regardless of any Swap Termination Payment or obligation under the Swap Agreement) and subsequently paying their portion of any Swap Termination Payment in respect of each such Class’s obligation under the Swap Agreement. In the event that any such Class is resecuritized in a REMIC, the obligation under the Swap Agreement to pay any such Swap Termination Payment (or any shortfall in Net Swap Payment), will be made by one or more of the REMIC Regular Interests issued by the resecuritization REMIC subsequent to such REMIC Regular Interest receiving its full payment from any such Offered Certificate and Class B-1 Certificate. Resecuritization of any Offered Certificate and Class B-1 Certificate in a REMIC will be permissible only if the Securities Administrator hereunder is the trustee/securities administrator in such resecuritization.

The REMIC Regular Interest corresponding to an Offered Certificate and Class B-1 Certificate will be entitled to receive interest and principal payments at the times and in the amounts equal to those made on the certificate to which it corresponds, except that (i) the maximum interest rate of that REMIC regular interest will equal the Net WAC Pass-Through Rate computed for this purpose by limiting the Swap Notional Amount of the Swap Agreement to the aggregate Scheduled Principal Balance of the Mortgage Loans and (ii) any Swap Termination Payment will be treated as being payable solely from amounts otherwise payable to the Class CE-1 Certificates. As a result of the foregoing, the amount of distributions and taxable income on the REMIC Regular Interest corresponding to an Offered Certificate and Class B-1 Certificate may exceed the actual amount of distributions on the Offered Certificate and Class B-1 Certificate.

ARTICLE II

THE CERTIFICATES

SECTION 6.01

The Certificates.

(a) The Certificates in the aggregate will represent the entire beneficial ownership interest in the Mortgage 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-6. 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 Class A Certificates and the Mezzanine 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 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) The Class B-1, Class CE-1 and Class CE-2 Certificates 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 6.02. 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 6.02. 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.

The Class B-1 Certificates offered and sold to Qualified Institutional Buyers (“QIBs”) in reliance on Rule 144A under the Securities Act (“Rule 144A”) or institutional investors that are accredited investors within the meaning of Rule 501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act (“Institutional Accredited Investors”) will be issued in the form of Book-Entry Certificates.

(d) The Class CE-1 Certificates and Class CE-2 Certificates offered and sold to 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 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 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. The Holder of a Regulation S Permanent 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 or Regulation S Permanent Global Certificate by the Book-Entry Custodian or the Depository or the Regulation S Permanent Global Certificate by the Depository, as applicable, 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 Regulation S Permanent 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 Regulation S Permanent 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, to the extent applicable with respect to such Definitive Certificates, and the Securities Administrator shall recognize the Holders of the Definitive Certificates as Certificateholders hereunder.

SECTION 6.02

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 9.11 of this Agreement, 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 Class B-1 Certificate, Class CE-1 Certificate, Class CE-2 Certificate or Residual Certificate shall be made unless that transfer is made pursuant to an effective registration statement under the Securities Act of 1933, as amended (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 Class B-1 Certificate, Class CE-1 Certificate, Class CE-2 Certificate or Residual 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) with respect to any Class B-1, Class CE-1 or Class CE-2 Certificate, if such transfer is purportedly being made in reliance or Regulation S, a written certification from the prospective transferee, substantially in the form of Exhibit B-1 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-1 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-1 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 CE-1, Class CE-2 or 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 Servicer, 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, any Servicer, the Trustee, the Master Servicer, the Securities Administrator or 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.

For so long as the Supplemental Interest Trust is in existence, each beneficial owner of a Offered Certificate or any interest therein, shall be deemed to have represented, by virtue of its acquisition or holding of the Offered Certificate, or interest therein, that either (i) it is not a Plan or (ii)(A) it is an accredited investor within the meaning of Prohibited Transaction Exemption 2002-41, as amended from time to time (the “Exemption”), (B) the acquisition and holding of such Certificate and the separate right to receive payments from the Supplemental Interest Trust are eligible for the exemptive relief available under Prohibited Transaction Class Exemption (“PTCE”) 84-14 (for transactions by independent “qualified professional asset managers”), 91-38 (for transactions by bank collective investment funds), 90-1 (for transactions by insurance company pooled separate accounts), 95-60 (for transactions by insurance company general accounts) or 96-23 (for transactions effected by “in-house asset managers”) and (C) in the case of a Mezzanine Certificate or a Class B-1 Certificate, it is an insurance company general account that meets the requirements of Section I of PTCE 95-60.

Each Transferee of a Mezzanine Certificate or a Class B-1 Certificate or any interest therein that is acquired after the termination of the Supplemental Interest Trust shall certify or 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 or (b) 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 6.02(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 6.02(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) (i) Each Person who has or who acquires any Ownership Interest in a Residual Certificate shall be deemed by the acceptance or acquisition of such Ownership Interest to have agreed to be bound by the following provisions and to have irrevocably authorized the

Securities Administrator or its designee under clause (iii)(A) below to deliver payments to a Person other than such Person and to negotiate the terms of any mandatory sale under clause (iii)(B) below and to execute all instruments of Transfer and to do all other things necessary in connection with any such sale. The rights of each Person acquiring any Ownership Interest in a Residual Certificate are expressly subject to the following provisions:

(A) Each Person holding or acquiring any Ownership Interest in a Residual Certificate 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.

(B) In connection with any proposed Transfer of any Ownership Interest in a Residual Certificate, the Securities Administrator shall require delivery to it, and shall not register the Transfer of any Residual Certificate until its receipt of, an affidavit and agreement (a “Transfer Affidavit and Agreement,” in the form attached hereto as Exhibit B-3) from the proposed Transferee, in form and substance satisfactory to the Securities Administrator, representing and warranting, among other things, that such Transferee is a Permitted Transferee, that it is not acquiring its Ownership Interest in the Residual Certificate that is the subject of the proposed Transfer as a nominee, trustee or agent for any Person that is not a Permitted Transferee, that for so long as it retains its Ownership Interest in a Residual Certificate, it will endeavor to remain a Permitted Transferee, and that it has reviewed the provisions of this Section 6.02(d) and agrees to be bound by them.

(C) Notwithstanding the delivery of a Transfer Affidavit and Agreement by a proposed Transferee under clause (B) above, if an authorized officer of the Securities Administrator who is assigned to this transaction has actual knowledge that the proposed Transferee is not a Permitted Transferee, no Transfer of an Ownership Interest in a Residual Certificate to such proposed Transferee shall be effected.

(D) Each Person holding or acquiring any Ownership Interest in a Residual Certificate shall agree (x) to require a Transfer Affidavit and Agreement from any other Person to whom such Person attempts to transfer its Ownership Interest in a Residual Certificate and (Y) not to transfer its Ownership Interest unless it provides a Transferor Affidavit (in the form attached hereto as Exhibit B-2) to the Securities Administrator stating that, among other things, it has no actual knowledge that such other Person is not a Permitted Transferee.

(E) Each Person holding or acquiring an Ownership Interest in a Residual Certificate, by purchasing an Ownership Interest in such Certificate, agrees to give the Securities Administrator written notice that it is a “pass-through interest holder” within the meaning of temporary Treasury regulation Section 1.67-3T(a)(2)(i)(A) immediately upon acquiring an Ownership Interest in a Residual Certificate, if it is, or is holding an Ownership Interest in a Residual Certificate on behalf of, a “pass-through interest holder.”

(ii) The Securities Administrator will register the Transfer of any Residual Certificate only if it shall have received the Transfer Affidavit and Agreement and all of such other documents as shall have been reasonably required by the Securities Administrator as a condition to such registration. In addition, no Transfer of a Residual Certificate shall be made unless the Securities Administrator shall have received a representation letter from the Transferee of such Certificate to the effect that such Transferee is a Permitted Transferee.

(iii) (A) If any purported Transferee shall become a Holder of a Residual Certificate in violation of the provisions of this Section 6.02(d), then the last preceding Permitted Transferee shall be restored, to the extent permitted by law, to all rights as holder thereof retroactive to the date of registration of such Transfer of such Residual Certificate. The Securities Administrator shall be under no liability to any Person for any registration of Transfer of a Residual Certificate that is in fact not permitted by this Section 6.02(d) or for making any payments due on such Certificate to the holder thereof or for taking any other action with respect to such holder under the provisions of this Agreement.

(B) If any purported Transferee shall become a holder of a Residual Certificate in violation of the restrictions in this Section 6.02(d) and to the extent that the retroactive restoration of the rights of the holder of such Residual Certificate as described in clause (iii)(A) above shall be invalid, illegal or unenforceable, then the Securities Administrator shall have the right, without notice to the holder or any prior holder of such Residual Certificate, to sell such Residual Certificate to a purchaser selected by the Securities Administrator on such terms as the Securities Administrator may choose. Such purported Transferee shall promptly endorse and deliver each Residual Certificate in accordance with the instructions of the Securities Administrator. Such purchaser may be the Securities Administrator itself or any Affiliate of the Securities Administrator. The proceeds of such sale, net of the commissions (which may include commissions payable to the Securities Administrator or its Affiliates), expenses and taxes due, if any, will be remitted by the Securities Administrator to such purported Transferee. The terms and conditions of any sale under this clause (iii)(B) shall be determined in the sole discretion of the Securities Administrator, and the Securities Administrator shall not be liable to any Person having an Ownership Interest in a Residual Certificate as a result of its exercise of such discretion.

(iv) The Securities Administrator shall make available to the Internal Revenue Service and those Persons specified by the REMIC Provisions all information necessary to compute any tax imposed (A) as a result of the Transfer of an Ownership Interest in a Residual Certificate to any Person who is a Disqualified Organization, including the information described in Treasury regulations sections 1.860D-1(b)(5) and 1.860E-2(a)(5) with respect to the “excess inclusions” of such Residual Certificate and (B) as a result of any regulated investment company, real estate investment trust, common trust fund, partnership, trust, estate or organization described in Section 1381 of the Code that holds an Ownership Interest in a Residual Certificate having as among its

record holders at any time any Person which is a Disqualified Organization. Reasonable compensation for providing such information may be charged or collected by the Securities Administrator.

(v) The provisions of this Section 6.02(d) set forth prior to this subsection (v) may be modified, added to or eliminated, provided that there shall have been delivered to the Securities Administrator at the expense of the party seeking to modify, add to or eliminate any such provision the following:

(A) written notification from each Rating Agency to the effect that the modification, addition to or elimination of such provisions will not cause such Rating Agency to downgrade its then-current ratings of any Class of Certificates; and

(B) an Opinion of Counsel, in form and substance satisfactory to the Securities Administrator, to the effect that such modification of, addition to or elimination of such provisions will not cause any Trust REMIC to cease to qualify as a REMIC and will not cause any Trust REMIC, as the case may be, to be subject to an entity-level tax caused by the Transfer of any Residual Certificate to a Person that is not a Permitted Transferee or a Person other than the prospective transferee to be subject to a REMIC-tax caused by the Transfer of a Residual Certificate to a Person that is not a Permitted Transferee.

(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 9.11 of this Agreement, 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 9.11 of this Agreement. 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. In addition, with respect to each Class R Certificate, the holder thereof may exchange, in the manner described above, such Class R Certificate for three separate certificates, each representing such holder's respective Percentage Interest in the Class R-I Interest, the Class R-II Interest and the Class R-III Interest, respectively, in each case that was evidenced by the Class R Certificate being exchanged.

(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 6.03

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 the 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 6.04

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 5.01 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 6.05

Certain Available Information.

On or prior to the date of the first sale of any Class B-1 Certificate, Class CE-1 Certificate, Class CE-2 Certificate or Residual 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 12.05 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 Class B-1 Certificate, Class CE-1 Certificate, Class CE-2 Certificate or Residual Certificate, the related 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 12.01 of this Agreement, (B) all monthly statements required to be delivered to Certificateholders of the relevant Class pursuant to Section 5.02 of this Agreement 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 a Servicer since the Closing Date delivered to the Master Servicer to evidence such Person’s determination that any P&I Advance or Servicing Advance was, or if made, would be a Nonrecoverable P&I 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.

The Depositor, Ocwen, Xxxxx Fargo or the Master Servicer may be merged or consolidated with or into any Person, or transfer all or substantially all of its assets to any Person, in which case any Person resulting from any merger or consolidation to which the Depositor, Ocwen, Xxxxx Fargo or the Master Servicer shall be a party, or any Person succeeding to the business of the Depositor, such Servicer or the Master Servicer, shall be the successor of the Depositor, such Servicer or the Master Servicer, as the case may be, hereunder, without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding; provided, however, that any successor to Ocwen, Xxxxx Fargo or the Master Servicer shall meet the eligibility requirements set forth in clauses (i) and (iii) of the last paragraph of Section 8.02(a) or Section 7.06 of this Agreement

SECTION 7.03 Limitation on Liability of the Depositor, Ocwen, Xxxxx Fargo, the Master Servicer and Others.

None of the Depositor, Ocwen, Xxxxx Fargo, the Securities Administrator, the Master Servicer or any of the directors, officers, employees or agents of the Depositor, Ocwen, Xxxxx Fargo or the Master Servicer shall be under any liability to the Trust Fund or the Certificateholders for any action taken or for refraining from the taking of any action in good faith pursuant to this Agreement or for errors in judgment; provided, however, that this provision shall not protect the Depositor Ocwen, Xxxxx Fargo, the Securities Administrator, the Master

Servicer or any such person against any breach of warranties, representations or covenants made herein or against any specific liability imposed on any such Person pursuant hereto or against any liability which would otherwise be imposed by reason of willful misfeasance, bad faith or gross negligence in the performance of duties or by reason of reckless disregard of obligations and duties hereunder. The Depositor, Ocwen, Xxxxx Fargo, the Securities Administrator, the Master Servicer and any director, officer, employee or agent of the Depositor, Ocwen, Xxxxx Fargo, the Securities Administrator and the Master Servicer may rely in good faith on any document of any kind which, prima facie, is properly executed and submitted by any Person respecting any matters arising hereunder.

Notwithstanding the foregoing, Ocwen and Xxxxx Fargo, without the consent of the Trustee or the Master Servicer, may retain third-party contractors to perform certain servicing and loan administration functions, including without limitation hazard insurance administration, tax payment and administration, flood certification and administration, collection services and similar functions, provided, however, that the retention of such contractors by the related Servicer shall not limit the obligation of such Servicer to service the related Mortgage Loans pursuant to the terms and conditions of this Agreement. Neither Ocwen not Xxxxx Fargo shall resign from the obligations and duties hereby imposed on it except by consent of the Master Servicer or upon determination that its duties hereunder are no longer permissible under applicable law. Any such determination pursuant to the preceding sentence permitting the resignation of Ocwen or Xxxxx Fargo shall be evidenced by an Opinion of Counsel to such effect obtained at the expense of the related Servicer and delivered to the Trustee and the Rating Agencies.

(b) Except as expressly provided herein, neither Ocwen nor Xxxxx Fargo shall assign or transfer any of its rights, benefits or privileges hereunder to any other Person, or delegate to or subcontract with, or authorize or appoint any other Person to perform any of the duties, covenants or obligations to be performed by the related Servicer hereunder. The foregoing prohibition on assignment shall not prohibit the related Servicer from designating a Sub-Servicer as payee of any indemnification amount payable to the related Servicer hereunder; provided, however, that as provided in Section 3.02 of this Agreement, no Sub-Servicer shall be a third-party beneficiary hereunder and the parties hereto shall not be required to recognize any Sub-Servicer as an indemnitee under this Agreement.

SECTION 7.05

Limitation on Resignation of the Master Servicer.

The Master Servicer shall not resign from the obligations and duties hereby imposed on it except upon determination that its duties hereunder are no longer permissible under applicable law. Any such determination pursuant to the preceding sentence permitting the resignation of the Master Servicer shall be evidenced by an Opinion of Counsel to such effect obtained at the expense of the Master Servicer and delivered to the Trustee and the Rating Agencies.

SECTION 7.06

$25,000,000 (unless otherwise approved by each Rating Agency pursuant to clause (ii) below); (b) shall be reasonably satisfactory to the Trustee (as evidenced in a writing signed by the Trustee); and (c) shall execute and deliver to the Trustee an agreement, in form and substance reasonably satisfactory to the Trustee, which contains an assumption by such Person of the due and punctual performance and observance of each covenant and condition to be performed or observed by it as master servicer under this Agreement, any custodial agreement from and after the effective date of such agreement; (ii) each Rating Agency shall be given prior written notice of the identity of the proposed successor to the Master Servicer and each Rating Agency’s rating of the Certificates in effect immediately prior to such assignment, sale and delegation will not be downgraded, qualified or withdrawn as a result of such assignment, sale and delegation, as evidenced by a letter to such effect delivered to the Master Servicer and the Trustee; and (iii) the Master Servicer assigning and selling the master servicing shall deliver to the Trustee an Officer’s Certificate and an Opinion of Independent counsel, each stating that all conditions precedent to such action under this Agreement have been completed and such action is permitted by and complies with the terms of this Agreement.

SECTION 7.07 Rights of the Depositor in Respect of Ocwen, Xxxxx Fargo and the Master Servicer.

The Master Servicer, Ocwen and Xxxxx Fargo hereto shall afford (and any Sub-Servicing Agreement shall provide that each Sub-Servicer shall afford) the Depositor and the Trustee, upon reasonable notice, during normal business hours, access to all records maintained by the Master Servicer or the related Servicer (and any such Sub-Servicer) in respect of the related Servicer’s rights and obligations hereunder and access to officers of the Master Servicer or such Servicer (and those of any such Sub-Servicer) responsible for such obligations, and the Master Servicer shall have access to all such records maintained by such Servicer and any Sub-Servicers. Upon request, each of the Master Servicer and the related Servicer shall furnish to the Depositor and the Trustee its (and any such Sub-Servicer’s) most recent financial statements and such other information relating to the Master Servicer’s or such Servicer’s capacity to perform its obligations under this Agreement as it possesses (and that any such Sub-Servicer possesses). To the extent that the Master Servicer, Ocwen or Xxxxx Fargo informs the Depositor and the Trustee that such information is not otherwise available to the public, the Depositor and the Trustee shall not disseminate any information obtained pursuant to the preceding two sentences without the Master Servicer’s or the related Servicer’s written consent, except as required pursuant to this Agreement or to the extent that it is appropriate to do so (i) to its legal counsel, auditors, taxing authorities or other governmental agencies and the Certificateholders, (ii) pursuant to any law, rule, regulation, order, judgment, writ, injunction or decree of any court or governmental authority having jurisdiction over the Depositor and the Trustee or the Trust Fund, and in any case, the Depositor or the Trustee, (iii) disclosure of any and all information that is or becomes publicly known, or information obtained by the Trustee from sources other than the Depositor, the related Servicer or the Master Servicer, (iv) disclosure as required pursuant to this Agreement or (v) disclosure of any and all information (A) in any preliminary or final offering circular, registration statement or contract or other document pertaining to the transactions contemplated by the Agreement approved in advance by the Depositor, the related Servicer or the Master Servicer or (B) to any affiliate, independent or internal auditor, agent, employee or attorney of

the Trustee having a need to know the same, provided that the Trustee advises such recipient of the confidential nature of the information being disclosed, shall use its best efforts to assure the confidentiality of any such disseminated non-public information. Nothing in this Section 7.07 shall limit the obligation of Ocwen or Xxxxx Fargo to comply with any applicable law prohibiting disclosure of information regarding the Mortgagors and the failure of Ocwen or Xxxxx Fargo to provide access as provided in this Section 7.07 as a result of such obligation shall not constitute a breach of this Section. Nothing in this Section 7.07 shall require Ocwen or Xxxxx Fargo to collect, create, collate or otherwise generate any information that it does not generate in its usual course of business. Ocwen and Xxxxx Fargo shall not be required to make copies of or ship documents to any party unless provisions have been made for the reimbursement of the costs thereof. The Depositor may, but is not obligated to, enforce the obligations of the Master Servicer, Ocwen and Xxxxx Fargo under this Agreement and may, but is not obligated to, perform, or cause a designee to perform, any defaulted obligation of the Master Servicer, Ocwen or Xxxxx Fargo under this Agreement or exercise the rights of the Master Servicer, Ocwen or Xxxxx Fargo under this Agreement; provided that none of the Master Servicer, Ocwen or Xxxxx Fargo shall be relieved of any of its obligations under this Agreement by virtue of such performance by the Depositor or its designee. The Depositor shall not have any responsibility or liability for any action or failure to act by the Master Servicer, Ocwen or Xxxxx Fargo and is not obligated to supervise the performance of the Master Servicer, Ocwen or Xxxxx Fargo under this Agreement or otherwise.

Additionally, the Securities Administrator (i) may not be an originator, Master Servicer, Servicer, the Depositor or an affiliate of the Depositor unless the Securities Administrator is in an institutional trust department, (ii) must be authorized to exercise corporate trust powers under the laws of its jurisdiction of organization, and (iii) must be rated at least "A/F1" by Fitch, if Fitch is a Rating Agency, or the equivalent rating by S&P (or such rating acceptable to Fitch pursuant to a rating confirmation). If no successor securities administrator shall have been appointed and shall have accepted appointment within 60 days after Xxxxx Fargo Bank, National Association, as Securities Administrator, ceases to be the securities administrator pursuant to this Section 9.06, then the Trustee shall perform the duties of the Securities Administrator pursuant to this Agreement. The Trustee shall notify the Rating Agencies of any change of Securities Administrator. Notwithstanding the above, the Trustee may, if it shall be unwilling to so act, or shall, if it is unable to so act, promptly appoint or petition a court of competent jurisdiction to appoint, a Person that satisfies the eligibility criteria set forth herein as the Trustee under this Agreement in the assumption of all or any part of the responsibilities, duties or liabilities of the Trustee under this Agreement.

SECTION 7.09

Limitation Upon Liability of the Credit Risk Manager.

Neither the Credit Risk Manager, nor any of its directors, officers, employees, or agents shall be under any liability to the Trustee, the Certificateholders, or the Depositor for any action taken or for refraining from the taking of any action made in good faith pursuant to this Agreement, in reliance upon information provided by a Servicer and/or Master Servicer under the related Credit Risk Management Agreement, or for errors in judgment; provided, however, that this provision shall not protect the Credit Risk Manager or any such person against liability that would otherwise be imposed by reason of willful malfeasance or bad faith in its performance of its duties. The Credit Risk Manager and any director, officer, employee, or agent of the Credit Risk Manager may rely in good faith on any document of any kind prima facie properly executed and submitted by any Person respecting any matters arising hereunder or under the related Credit Risk Management Agreement, and may rely in good faith upon the accuracy of information furnished by a Servicer and/or Master Servicer pursuant to the related Credit Risk Management Agreement in the performance of its duties thereunder and hereunder. The Credit Risk Manager shall be held harmless and indemnified by the Trust Fund for any claims, costs or liability (each a “Claim”) arising out of or related in any way to the performance of its duties hereunder absent bad faith, willful misfeasance or gross negligence on the part of the Credit Risk Manager with respect to the applicable Claim and the legal expenses for any applicable Claim shall be expenses, costs and liabilities of the Trust Fund.

SECTION 7.10

Removal of the Credit Risk Manager.

So long as Deutsche Bank Securities Inc. is the Holder of the Class CE-1 Certificate it may, at its option, terminate the Credit Risk Manager if the Credit Risk Manager breaches its obligations under the Credit Risk Management Agreements in any material respect and has not cured such breach as promptly as practicable but in no event later than 30 days after receiving written notice of such breach. In the event that a party other than Deutsche Bank Securities Inc. is the Holder of the Class CE-1 Certificate, the Holder of the Class CE-1 Certificate shall not have such termination right. In addition, the Credit Risk Manager may be removed as Credit Risk Manager under both Credit Risk Management Agreements by Certificateholders holding not less than 66 2/3% of the Voting Rights in the Trust Fund, in the exercise of its or their sole discretion. Upon the termination of the Credit Risk Manager by the Certificateholders or Deutsche Bank Securities Inc. as provided above, the Certificateholders or Deutsche Bank Securities Inc., as applicable, shall provide written notice of the Credit Risk Manager’s removal to the Trustee and the Servicers. Upon receipt of such notice, the Trustee shall provide written notice to the Credit Risk Manager of its removal, which shall be effective upon receipt of such notice by the Credit Risk Manager with a copy to the Securities Administrator and the Master Servicer.

Upon the termination of the Credit Risk Manager by the Holder of the Class CE-1 Certificate as provided above, the Holder of the Class CE-1 Certificate may, at its option, appoint a successor Credit Risk Manager. If the Holder of the Class CE-1 Certificate fails to appoint a successor Credit Risk Manager, the Depositor may appoint a successor Credit Risk Manager. Upon the termination of the Credit Risk Manager by the Certificateholders as provided above, the Depositor shall appoint a successor Credit Risk Manager. Notwithstanding the foregoing, the

termination of the Credit Risk Manager pursuant to this Section shall not become effective until the appointment of a successor Credit Risk Manager.

For purposes of this Section 8.01(a), the Trustee shall not be deemed to have knowledge of a Servicer Event of Default unless a Responsible Officer of the Trustee assigned to and working in the Trustee’s Corporate Trust Office has actual knowledge thereof or unless written notice of any event which is in fact such a Servicer Event of Default is received by the Trustee at its Corporate Trust Office and such notice references the Certificates, the Trust or this Agreement. The Trustee shall promptly notify the Master Servicer and the Rating Agencies of the occurrence of a Servicer Event of Default of which it has knowledge as provided above.

The Master Servicer or other successor Servicer shall be entitled to be reimbursed by the defaulting Servicer (or from amounts on deposit in the Distribution Account if the defaulting Servicer is unable to fulfill its obligations hereunder) for all reasonable out-of-pocket or third party costs associated with the transfer of servicing from the predecessor Servicer (or if the predecessor Servicer is the Master Servicer, from the Servicer immediately preceding the Master Servicer), including without limitation, any reasonable out-of-pocket or third party costs or expenses associated with the complete transfer of all servicing data and the completion, correction or manipulation of such servicing data as may be required by the Master Servicer to correct any errors or insufficiencies in the servicing data or otherwise to enable the Master Servicer to service the Mortgage Loans properly and effectively, upon presentation of reasonable documentation of such costs and expenses.

(b) “Master Servicer Event of Default,” wherever used herein, means any one of the following events:

(i) any failure on the part of the Master Servicer duly to observe or perform in any material respect any other of the covenants or agreements on the part of the Master Servicer contained in this Agreement, or the breach by the Master Servicer of any representation and warranty contained in Section 2.04, which continues unremedied for a period of 30 days after the date on which written notice of such failure, requiring the same to be remedied, shall have been given to the Master Servicer by the Depositor or the

If a Master Servicer Event of Default shall occur, then, and in each and every such case, so long as such Master Servicer Event of Default shall not have been remedied, the Depositor or the Trustee may, and at the written direction of the Holders of Certificates entitled to at least 51% of Voting Rights, the Trustee shall, by notice in writing to the Master Servicer (and to the Depositor if given by the Trustee or to the Trustee if given by the Depositor) with a copy to each Rating Agency, terminate all of the rights and obligations of the Master Servicer in its capacity as Master Servicer under this Agreement, to the extent permitted by law, and in and to the Mortgage Loans and the proceeds thereof. On or after the receipt by the Master Servicer of such written notice, all authority and power of the Master Servicer under this Agreement, whether with respect to the Certificates (other than as a Holder of any Certificate) or the Mortgage Loans or otherwise including, without limitation, the compensation payable to the Master Servicer under this Agreement, shall pass to and be vested in the Trustee pursuant to and under this Section, and, without limitation, the Trustee is hereby authorized and empowered, as attorney-in-fact or otherwise, to execute and deliver, on behalf of and at the expense of the Master Servicer, any and all documents and other instruments and to do or accomplish all other acts or things necessary or appropriate to effect the purposes of such notice of termination, whether to complete the transfer and endorsement or assignment of the Mortgage Loans and related documents, or otherwise.

For purposes of this Section 8.01(b), the Trustee

shall not be deemed to have knowledge of a Master Servicer Event of Default unless a Responsible Officer of the Trustee assigned to and working in the Trustee’s Corporate Trust Office has actual knowledge thereof or unless written notice of any event which is in fact such a Master Servicer Event of Default is received by the Trustee and such notice references the Certificates, the Trust or this Agreement. The Trustee shall promptly notify the Rating Agencies of the occurrence of a Master Servicer Event of Default of which it has knowledge as provided above.

To the extent that the costs and expenses of the Trustee related to the termination of the Master Servicer, appointment of a successor Master Servicer or the transfer and assumption of the master servicing by the Trustee (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 Master Servicer as a result of a Master Servicer Event of Default and (ii) all costs and expenses associated with the complete transfer of the master 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 Master Servicer to correct any errors or insufficiencies in the servicing data or otherwise to enable the successor Master Servicer to master service the Mortgage Loans in accordance with this Agreement) are not fully and timely reimbursed by the terminated Master Servicer, the Trustee shall be entitled to reimbursement of such costs and expenses from the Distribution Account.

Notwithstanding the foregoing, the Trustee may, if it shall be unwilling to continue to act, or shall, if it is unable to so act, petition a court of competent jurisdiction to appoint, or appoint on its own behalf, any established housing and home finance institution servicer, master servicer, servicing or mortgage servicing institution having a net worth of not less than $25,000,000 and meeting such other standards for a successor master servicer as are set forth in this Agreement, as the successor to such Master Servicer in the assumption of all of the responsibilities, duties or liabilities of a master servicer.

SECTION 8.02

Master Servicer to Act; Appointment of Successor.

(a) On and after the time a Servicer receives a notice of termination, the Master Servicer or other successor Servicer as appointed by the Trustee shall be the successor in all respects to such Servicer in its capacity as a Servicer under this Agreement or the Servicing Agreement, as applicable, and the transactions set forth or provided for herein or therein, and all the responsibilities, duties and liabilities relating thereto and arising thereafter shall be assumed by the Master Servicer or such successor Servicer (except for any representations or warranties of the related Servicer under this Agreement or the Servicing Agreement, as applicable, the responsibilities, duties and liabilities contained in Section 2.03 of this Agreement and the obligation to deposit amounts in respect of losses pursuant to Section 3.10(b) of this Agreement) by the terms and provisions hereof including, without limitation, the related Servicer’s obligations to make P&I Advances pursuant to Section 5.03 of this Agreement or pursuant to the Servicing Agreement; provided that the Trustee shall be obligated to make P&I Advances in connection with the Xxxxx Fargo Mortgage Loans in the event Xxxxx Fargo is terminated as Servicer hereunder; provided, further, that if the Master Servicer or the Trustee, is prohibited by law or regulation from obligating itself to make advances regarding delinquent mortgage loans, then the Master Servicer shall not be obligated to make P&I Advances pursuant to Section 5.03

of this Agreement or pursuant to the Servicing Agreement; and provided further, that any failure to perform such duties or responsibilities caused by the related Servicer’s failure to provide information required by Section 8.01 of this Agreement or under the Servicing Agreement shall not be considered a default by the Master Servicer as successor to such Servicer hereunder; provided, however, that (1) it is understood and acknowledged by the parties hereto that there will be a period of transition (not to exceed 120 days) before the actual servicing functions can be fully transferred to the Master Servicer or any successor Servicer appointed in accordance with the following provisions and (2) any failure to perform such duties or responsibilities caused by the related Servicer’s failure to provide information required by Section 8.01 of this Agreement or under the Servicing Agreement shall not be considered a default by the Master Servicer as successor to such Servicer. As compensation therefor, the Master Servicer or the Trustee, as applicable, shall be entitled to the Servicing Fee and all funds relating to the Mortgage Loans to which the terminated Servicer would have been entitled if it had continued to act hereunder or under the Servicing Agreement. Notwithstanding the above and subject to the immediately following paragraph, the Master Servicer may, if it shall be unwilling to so act, or shall, if it is unable to so act promptly appoint or petition a court of competent jurisdiction to appoint, a Person that satisfies the eligibility criteria set forth below as the successor to the terminated Servicer under this Agreement or under the Servicing Agreement in the assumption of all or any part of the responsibilities, duties or liabilities of the related Servicer under this Agreement or under the Servicing Agreement.

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

Any successor Servicer appointed under this Agreement must (i) be an established mortgage loan servicing institution that is a Xxxxxx Mae and Xxxxxxx Mac approved seller/servicer, (ii) be approved by each Rating Agency by a written confirmation from each Rating Agency that the appointment of such successor Servicer would not result in the reduction or withdrawal of the then current ratings of any outstanding Class of Certificates, (iii) have a net worth of not less than $25,000,000 and (iv) assume all the responsibilities, duties or liabilities of the related Servicer (other than liabilities of the related Servicer hereunder incurred prior to termination of the related Servicer under Section 8.01 herein) under this Agreement as if originally named as a party to this Agreement.

(b) (1) All servicing transfer costs (including, without limitation, servicing transfer costs of the type described in Section 8.02(a) of this Agreement and incurred by the Trustee, the Master Servicer and any successor Servicer under paragraph (b)(2) below) in connection with the termination of a Servicer shall be paid by the terminated Servicer upon presentation of reasonable documentation of such costs, and if such predecessor or initial Servicer, as applicable, defaults in its obligation to pay such costs, the successor Servicer, the Master Servicer and the Trustee shall be entitled to reimbursement therefor from the assets of the Trust Fund.

(2) No appointment of a successor to a Servicer under this Agreement shall be effective until the assumption by the successor of all of such Servicer’s responsibilities, duties and liabilities hereunder. In connection with such appointment and assumption described herein, the Trustee may make such arrangements for the compensation of such successor out of payments on the related Mortgage Loans as it and such successor shall agree; provided, however, that no such compensation shall be in excess of that permitted the related Servicer as such hereunder or under the Servicing 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 a Servicer under this Agreement, the Master Servicer shall act in such capacity as hereinabove provided.

SECTION 8.03

Notification to Certificateholders.

(a) Upon any termination of a Servicer or the Master Servicer pursuant to the Servicing Agreement or Section 8.01(a) of this Agreement, as applicable, or (b) or any appointment of a successor to a Servicer or the Master Servicer pursuant to the Servicing Agreement or Section 8.02 of this Agreement, as applicable, the Trustee shall give prompt written notice thereof to the Certificateholders at the expense of the Trust Fund at their respective addresses appearing in the Certificate Register.

(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 Servicer Event of Default or 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 Servicer Event of Default or Master Servicer Event of Default shall have been cured or waived.

SECTION 8.04

Waiver of Servicer Events of Default.

The Holders representing at least 66% of the Voting Rights evidenced by all Classes of Certificates affected by any default, Servicer Event of Default or Master Servicer Event of Default hereunder may waive such default, Servicer Event of Default or Master Servicer Event of Default; provided, however, that a Servicer Event of Default under clause (i) or (vii) of Section 8.01(a) of this Agreement may be waived only by all of the Holders of the Regular Certificates. Upon any such waiver of a default, Servicer Event of Default or Master Servicer Event of Default, such default, Servicer Event of Default or Master Servicer Event of Default shall cease to exist and shall be deemed to have been remedied for every purpose hereunder. No such waiver shall extend to any subsequent or other default, Servicer Event of Default or Master Servicer Event of Default or impair any right consequent thereon except to the extent expressly so waived.

The Trustee, prior to the occurrence of a Master Servicer Event of Default and after the curing or waiver of all Master Servicer Events of Default which may have occurred, and the Securities Administrator each undertake to perform such duties and only such duties as are specifically set forth in this Agreement as duties of the Trustee and the Securities Administrator, respectively. During the continuance of a Master Servicer Event of Default, the Trustee shall exercise such of the rights and powers vested in it by this Agreement, and use the same degree of care and skill in its exercise as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs. Any permissive right of the Trustee enumerated in this Agreement shall not be construed as a duty.

Each of the Trustee and the Securities Administrator, upon receipt of all resolutions, certificates, statements, opinions, reports, documents, orders or other instruments furnished to it, which are specifically required to be furnished pursuant to any provision of this Agreement, shall examine them to determine whether they conform to the requirements of this Agreement. If any such instrument is found not to conform to the requirements of this Agreement in a material manner, the Trustee or the Securities Administrator, as the case may be, shall take such action as it deems appropriate to have the instrument corrected, and if the instrument is not corrected to its satisfaction, the Securities Administrator will provide notice to the Trustee thereof and the Trustee will provide notice to the Certificateholders.

The Trustee shall promptly remit to the related Servicer any complaint, claim, demand, notice or other document (collectively, the “Notices”) delivered to the Trustee as a consequence of the assignment of any Mortgage Loan hereunder and relating to the servicing of the Mortgage Loans; provided than any such notice (i) is delivered to the Trustee at its Corporate Trust Office, (ii) is in writing and contains information sufficient to permit the Trustee to make a determination that the real property to which such document relates is a Mortgaged Property. The Trustee shall have no duty hereunder with respect to any Notice it may receive or which may be alleged to have been delivered to or served upon it unless such Notice is delivered to it or served upon it at its Corporate Trust Office and such Notice contains the information required pursuant to clause (ii) of the preceding sentence.

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

(i) Prior to the occurrence of a Master Servicer Event of Default, and after the curing or waiver of all such Master Servicer Events of Default which may have occurred with respect to the Trustee and at all times with respect to the Securities Administrator, the duties and obligations of the Trustee shall be determined solely by the express provisions of this Agreement, neither the Trustee nor the Securities Administrator shall be liable except for the performance of such duties and obligations as are

specifically set forth in this Agreement, no implied covenants or obligations shall be read into this Agreement against the Trustee or the Securities Administrator and, in the absence of bad faith on the part of the Trustee or the Securities Administrator, respectively, the Trustee or the Securities Administrator, respectively, may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee or the Securities Administrator, respectively, that conform to the requirements of this Agreement;

(ii) Neither the Trustee nor the Securities Administrator shall be liable for an error of judgment made in good faith by a Responsible Officer or Responsible Officers of the Trustee or an officer or officers of the Securities Administrator, respectively, unless it shall be proved that the Trustee or the Securities Administrator, respectively, was negligent in ascertaining the pertinent facts; and

(iii) Neither the Trustee nor the Securities Administrator shall be liable with respect to any action taken, suffered or omitted to be taken by it in good faith in accordance with the direction of the Holders of Certificates entitled to at least 25% of the Voting Rights relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee or the Securities Administrator or exercising any trust or power conferred upon the Trustee or the Securities Administrator under this Agreement.

(viii) The Trustee shall not be deemed to have notice of any default, Master Servicer Event of Default or Servicer Event of Default unless a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a default is received by a Responsible Officer of the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Certificates and this Agreement; and

(ix) The rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to,

SECTION 11.01

(a) The Trustee shall elect to treat each Trust REMIC as a REMIC under the Code and, if necessary, under applicable state law. Each such election will be made by the Securities Administrator on Form 1066 or other appropriate federal tax or information return or any appropriate state return for the taxable year ending on the last day of the calendar year in which the Certificates are issued. For the purposes of the REMIC election in respect of REMIC I, the REMIC I Regular Interests shall be designated as the “regular interests” in REMIC I and the Class R-I Interest shall be designated as the “residual interest” in REMIC I. For the purposes of the REMIC election in respect of REMIC II, the REMIC II Regular Interests shall be designated as the “regular interests” in REMIC II and the Class R-II Interest shall be designated as the “residual interest” in REMIC II. The Class A Certificates, Mezzanine Certificates, Class B-1 Certificates, Class IO Interest, Class CE-1 Certificates and Class CE-2 Certificates (exclusive of any right to receive payments from the Reserve Fund) shall be designated as the “regular interests” in REMIC III and the Class R-III Interest shall be designated as the “residual interest” in REMIC III. The Trustee shall not permit the creation of any “interests” in each Trust REMIC (within the meaning of Section 860G of the Code) other than the REMIC I Regular Interests, REMIC II Regular Interests, Class IO Interest and the interests represented by the Certificates.

(b) The Closing Date is hereby designated as the “Startup Day” of each Trust REMIC within the meaning of Section 860G(a)(9) of the Code.

(c) The Securities Administrator shall be reimbursed for any and all expenses relating to any tax audit of the Trust Fund (including, but not limited to, any professional fees or any administrative or judicial proceedings with respect to each Trust REMIC that involve the Internal Revenue Service or state tax authorities), including the expense of obtaining any tax related Opinion of Counsel except as specified herein. The Securities Administrator, as agent for each Trust REMIC’s tax matters person shall (i) act on behalf of the Trust Fund in relation to any tax matter or controversy involving any Trust REMIC and (ii) represent the Trust Fund in any administrative or judicial proceeding relating to an examination or audit by any governmental taxing authority with respect thereto. The holder of the largest Percentage Interest of each Class of Residual Certificates shall be designated, in the manner provided under Treasury regulations section 1.860F-4(d) and Treasury regulations section 301.6231(a)(7)-1, as the tax matters person of the related REMIC created hereunder. By their acceptance thereof, the holder of the largest Percentage Interest of the Residual Certificates hereby agrees to irrevocably appoint the Securities Administrator or an Affiliate as its agent to perform all of the duties of the tax matters person for the Trust Fund.

(d) The Securities Administrator shall prepare and file and the Trustee shall sign all of the Tax Returns in respect of each REMIC created hereunder. The expenses of preparing and filing such returns shall be borne by the Securities Administrator without any right of reimbursement therefor.

(e) The Securities Administrator shall perform on behalf of each Trust REMIC all reporting and other tax compliance duties that are the responsibility of such REMIC under the Code, the REMIC Provisions or other compliance guidance issued by the Internal Revenue Service or any state or local taxing authority. Among its other duties, as required by the Code, the REMIC Provisions or other such compliance guidance, the Securities Administrator shall provide (i) to any Transferor of a Residual Certificate such information as is necessary for the application of any tax relating to the transfer of a Residual Certificate to any Person who is not a Permitted Transferee upon receipt of additional reasonable compensation, (ii) to the Certificateholders such information or reports as are required by the Code or the REMIC Provisions including reports relating to interest, original issue discount and market discount or premium (using the Prepayment Assumption as required) and (iii) to the Internal Revenue Service the name, title, address and telephone number of the person who will serve as the representative of each Trust REMIC. The Depositor shall provide or cause to be provided to the Securities Administrator, within ten (10) days after the Closing Date, all information or data that the Securities Administrator reasonably determines to be relevant for tax purposes as to the valuations and issue prices of the Certificates, including, without limitation, the price, yield, prepayment assumption and projected cash flow of the Certificates.

(f) To the extent in the control of the Trustee or the Securities Administrator, each such Person (i) shall take such action and shall cause each REMIC created hereunder to take such action as shall be necessary to create or maintain the status thereof as a REMIC under the REMIC Provisions, (ii) shall not take any action, cause the Trust Fund to take any action or fail to take (or fail to cause to be taken) any action that, under the REMIC Provisions, if taken or not taken, as the case may be, could (A) endanger the status of each Trust REMIC as a REMIC or (B) 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) (either such event, an “Adverse REMIC Event”) unless such action or inaction is permitted under this Agreement or the Trustee and the Securities Administrator have received an Opinion of Counsel, addressed to the them (at the expense of the party seeking to take such action but in no event at the expense of the Trustee or the Securities Administrator) to the effect that the contemplated action will not, with respect to any Trust REMIC, endanger such status or result in the imposition of such a tax, nor (iii) shall the Securities Administrator take or fail to take any action (whether or not authorized hereunder) as to which the Trustee has advised it in writing that it has received an Opinion of Counsel to the effect that an Adverse REMIC Event could occur with respect to such action; provided that the Securities Administrator may conclusively rely on such Opinion of Counsel and shall incur no liability for its action or failure to act in accordance with such Opinion of Counsel. In addition, prior to taking any action with respect to any Trust REMIC or the respective assets of each, or causing any Trust REMIC to take any action, which is not contemplated under the terms of this Agreement, the Securities Administrator will consult with the Trustee or its designee, in writing, with respect to whether such action could cause an Adverse REMIC Event to occur with respect to any Trust REMIC, and the Securities Administrator shall not take any such action or cause any Trust 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 home 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 11.03 of this Agreement, if such tax arises out of or results from a breach by the Trustee of any of its obligations under this Article XI, (ii) to the Securities Administrator pursuant to Section 11.03 of this Agreement, if such tax arises out of or results from a breach by the Securities Administrator of any of its obligations under this Article XI, (iii) to the Master Servicer pursuant to Section 11.03 of this Agreement, if such tax arises out of or results from a breach by the Master Servicer of any of its obligations under Article IV or under this Article XI, (iv) to the related Servicer pursuant to Section 11.03 of this Agreement, if such tax arises out of or results from a breach by a Servicer of any of its obligations under Article III or under this Article XI, or (v) in all other cases, against amounts on deposit in the Distribution Account and shall be paid by withdrawal therefrom.

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

(i) Following the Startup Day, neither the Securities Administrator nor the Trustee shall accept any contributions of assets to any Trust REMIC other than in connection with any Qualified Substitute Mortgage Loan delivered in accordance with Section 2.03 unless it shall have received an Opinion of Counsel 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 Trust REMIC will receive a fee or other compensation for services nor permit either 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. In connection with the foregoing, the Securities Administrator shall provide the name and address of the person who can be contacted to obtain information required to be reported to the holders of Regular Interests in each REMIC as required by IRS Form 8811.

SECTION 11.03

Indemnification.

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

Accordingly, the Depositor hereby grants to the Trustee, on behalf of the Trust and for the benefit of the Certificateholders, a security interest in the Mortgage 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.

This Certificate is one of a duly authorized issue of Certificates designated as Asset Backed 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 obligations created by the Agreement and the Trust Fund created thereby shall terminate upon payment to the Certificateholders of all amounts held by the Securities Administrator and required to be paid to them pursuant to the Agreement following the earlier of (i) the final payment or other liquidation (or any advance with respect thereto) of the last Mortgage Loan remaining in REMIC I and (ii) the purchase by the party designated in the Agreement at a price determined as provided in the Agreement from REMIC I 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 from REMIC I 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 properties acquired in respect thereof) at the time of purchase being less than or equal to 10% of the aggregate Scheduled Principal Balance of the Mortgage Loans as of the Cut-off Date.

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.

COUNTY OF NEW YORK	)

___________________________ being duly sworn, deposes, represents and warrants as follows:

I am a _____________________ of _______________________________ (the “Owner”) a corporation duly organized and existing under the laws of _________________________, the record owner of ACE Securities Corp. Home Equity Loan Trust, Series 2005-SD3 Asset Backed Pass-Through Certificates, Class R Certificates (the “Class R Certificates”), on behalf of whom I make this affidavit and agreement. Capitalized terms used but not defined herein have the respective meanings assigned thereto in the Pooling and Servicing Agreement pursuant to which the Class R Certificates were issued.

The Owner (i) is and will be a “Permitted Transferee” as of ____________________. ____ and (ii) is acquiring the Class R Certificates for its own account or for the account of another Owner from which it has received an affidavit in substantially the same form as this affidavit. A “Permitted Transferee” is any person other than a “disqualified organization” or a possession of the United States. For this purpose, a “disqualified organization” means the United States, any state or political subdivision thereof, any agency or instrumentality of any of the foregoing (other than an instrumentality all of the activities of which are subject to tax and, except for the Federal Home Loan Mortgage Corporation, a majority of whose board of directors is not selected by any such governmental entity) or any foreign government, international organization or any agency or instrumentality of such foreign government or organization, any real electric or telephone cooperative, or any organization (other than certain farmers’ cooperatives) that is generally exempt from federal income tax unless such organization is subject to the tax on unrelated business taxable income.

3.	The Owner is aware (i) of the tax that would be imposed on transfers of the Class R Certificates to disqualified organizations under the Internal Revenue Code of 1986 that applies to all transfers of the Class R Certificates after April 31, 1988; (ii) that such tax would be on the transferor or, if such transfer is through an agent (which person includes a broker, nominee or middleman) for a non-Permitted Transferee, on the agent; (iii) that the person otherwise liable for the tax shall be relieved of liability for the tax if the transferee furnishes to such person an affidavit that the transferee is a Permitted Transferee and, at the time of transfer, such person does not have actual knowledge that the affidavit is false; and (iv) that each of the Class R Certificates may be a “noneconomic residual interest” within the meaning of proposed Treasury regulations promulgated under the Code and that the transferor of a “noneconomic residual interest” will remain liable for any taxes due with respect to the income on such residual interest, unless no significant purpose of the transfer is to impede the assessment or collection of tax.
4.	The Owner is aware of the tax imposed on a “pass-through entity” holding the Class R Certificates if, at any time during the taxable year of the pass-through entity, a non-Permitted Transferee is the record holder of an interest in such entity. (For this purpose, a “pass-through entity” includes a regulated investment company, a real estate investment trust or common trust fund, a partnership, trust or estate, and certain cooperatives.)
5.	The Owner is aware that the Securities Administrator will not register the transfer of any Class R Certificate unless the transferee, or the transferee’s agent, delivers to the Securities Administrator, among other things, an affidavit in substantially the same form as this affidavit. The Owner expressly agrees that it will not consummate any such transfer if it knows or believes that any of the representations contained in such affidavit and agreement are false.
6.	The Owner consents to any additional restrictions or arrangements that shall be deemed necessary upon advice of counsel to constitute a reasonable arrangement to ensure that the Class R Certificates will only be owned, directly or indirectly, by an Owner that is a Permitted Transferee.
7.	The Owner’s taxpayer identification number is ________________.
8.	The Owner has reviewed the restrictions set forth on the face of the Class R Certificates and the provisions of Section 6.02(d) of the Pooling and Servicing Agreement under which the Class R Certificates were issued (in particular, clauses (iii)(A) and (iii)(B) of Section 6.02(d) which authorize the Securities Administrator to deliver payments to a person other than the Owner and negotiate a mandatory sale by the Securities Administrator in the event that the Owner holds such Certificate in violation of Section 6.02(d)); and that the Owner expressly agrees to be bound by and to comply with such restrictions and provisions.
9.	The Owner is not acquiring and will not transfer the Class R Certificates in order to impede the assessment or collection of any tax.
10.	The Owner anticipates that it will, so long as it holds the Class R Certificates, have sufficient assets to pay any taxes owed by the holder of such Class R Certificates, and hereby represents to and for the benefit of the person from whom it acquired the Class R Certificates that the Owner intends to pay taxes associated with holding such Class R Certificates as they become due, fully understanding that it may incur tax liabilities in excess of any cash flows generated by the Class R Certificates.

11.	The Owner has no present knowledge that it may become insolvent or subject to a bankruptcy proceeding for so long as it holds the Class R Certificates.
12.	The Owner has no present knowledge or expectation that it will be unable to pay any United States taxes owed by it so long as any of the Certificates remain outstanding.
13.	The Owner is not acquiring the Class R Certificates with the intent to transfer the Class R Certificates to any person or entity that will not have sufficient assets to pay any taxes owed by the holder of such Class R Certificates, or that may become insolvent or subject to a bankruptcy proceeding, for so long as the Class R Certificates remain outstanding.
14.	The Owner will, in connection with any transfer that it makes of the Class R Certificates, obtain from its transferee the representations required by Section 6.02(d) of the Pooling and Servicing Agreement under which the Class R Certificate were issued and will not consummate any such transfer if it knows, or knows facts that should lead it to believe, that any such representations are false.
15.	The Owner will, in connection with any transfer that it makes of the Class R Certificates, deliver to the Securities Administrator an affidavit, which represents and warrants that it is not transferring the Class R Certificates to impede the assessment or collection of any tax and that it has no actual knowledge that the proposed transferee: (i) has insufficient assets to pay any taxes owed by such transferee as holder of the Class R Certificates; (ii) may become insolvent or subject to a bankruptcy proceeding for so long as the Class R Certificates remains outstanding; and (iii) is not a “Permitted Transferee”.
16.	The Owner is a citizen or resident of the United States, a corporation, partnership or other entity created or organized in, or under the laws of, the United States or any political subdivision thereof, or an estate or trust whose income from sources without the United States may be included in gross income for United States federal income tax purposes regardless of its connection with the conduct of a trade or business within the United States.
17.	The Owner of the Class R Certificate, hereby agrees that in the event that the Trust Fund created by the Pooling and Servicing Agreement is terminated pursuant to Section 10.01 thereof, the undersigned shall assign and transfer to the Holders of the Class CE-1 Certificates any amounts in excess of par received in connection with such termination. Accordingly, in the event of such termination, the Securities Administrator is hereby authorized to withhold any such amounts in excess of par and to pay such amounts directly to the Holders of the Class CE-1 Certificates. This agreement shall bind and be enforceable against any successor, transferee or assigned of the undersigned in the Class R Certificate. In connection with any transfer of the Class R Certificate, the Owner shall obtain an agreement substantially similar to this clause from any subsequent owner.
