Conveyance of Trust Fund.

Pursuant to the Mortgage Loan Purchase Agreement, the Seller sold, transferred, assigned, set over and otherwise conveyed to the Depositor, without recourse, all the right, title and interest of the Seller in and to the assets in the Trust Fund.

The Seller has entered into this Agreement in consideration for the purchase of the Mortgage Loans by the Depositor pursuant to the Mortgage Loan Purchase Agreement and has agreed to take the actions specified herein.

The Depositor, concurrently with the execution and delivery hereof, hereby sells, transfers, assigns, sets over and otherwise conveys to the Trustee for the use and benefit of the Certificateholders, without recourse, all the right, title and interest of the Depositor in and to the Trust Fund.

In connection with such sale, the Depositor has delivered to, and deposited with, the Trustee or the Custodian, as its agent, the following documents or instruments with respect to each Mortgage Loan so assigned: (i) the original Mortgage Note, including any riders thereto, endorsed without recourse (A) to the order of “U.S. Bank National Association, as Trustee for certificateholders of Bear Stearns Asset Backed Securities I LLC, Asset Backed Certificates, Series 2005-AC4,” or (B) in the case of a loan registered on the MERS system, in blank, and in each case showing to the extent available to the Seller an unbroken chain of endorsements from the original payee thereof to the Person endorsing it to the Trustee, (ii) the original Mortgage and, if the related Mortgage Loan is a MOM Loan, noting the presence of the MIN and language indicating that such Mortgage Loan is a MOM Loan, which shall have been recorded (or if the original is not available, a copy), with evidence of such recording indicated thereon (or if clause (x) in the proviso below applies, shall be in recordable form), (iii) unless the Mortgage Loan is a MOM Loan, the assignment (either an original or a copy, which may be in the form of a blanket assignment if permitted in the jurisdiction in which the Mortgaged Property is located) to the Trustee of the Mortgage with respect to each Mortgage Loan in the name of “U.S. Bank National Association, as Trustee for certificateholders of Bear Stearns Asset Backed Securities I LLC, Asset Backed Certificates, Series 2005-AC4,” which shall have been recorded (or if clause (x) in the proviso below applies, shall be in recordable form) (iv) an original or a copy of all intervening assignments of the Mortgage, if any, to the extent available to the Seller, with evidence of recording thereon, (v) the original policy of title insurance or mortgagee’s certificate of title insurance or commitment or binder for title insurance, if available, or a copy thereof, or, in the event that such original title insurance policy is unavailable, a photocopy thereof, or in lieu thereof, a current lien search on the related Mortgaged Property and (vi) originals or copies of all available assumption, modification or substitution agreements, if any; provided, however, that in lieu of the foregoing, the Seller may deliver the following documents, under the circumstances set forth below: (x) if any Mortgage, assignment thereof to the Trustee or intervening assignments thereof have been delivered or are being delivered to recording offices for recording and have not been returned in time to permit their delivery as specified above, the Depositor may

deliver a true copy thereof with a certification by the Seller or the title company issuing the commitment for title insurance, on the face of such copy, substantially as follows: “Certified to be a true and correct copy of the original, which has been transmitted for recording” and (y) in lieu of the Mortgage Notes relating to the Mortgage Loans identified in the list set forth in Exhibit I, the Depositor may deliver a lost note affidavit and indemnity and a copy of the original note, if available; and provided, further, however, that in the case of Mortgage Loans which have been prepaid in full after the Cut-off Date and prior to the Closing Date, the Depositor, in lieu of delivering the above documents, may deliver to the Trustee and its Custodian a certification of a Servicing Officer to such effect and in such case shall deposit all amounts paid in respect of such Mortgage Loans, in the Master Servicer Collection Account or in the Distribution Account on the Closing Date. In the case of the documents referred to in clause (x) above, the Depositor shall deliver such documents to the Trustee or its Custodian promptly after they are received. The Seller shall cause, at its expense, the Mortgage and intervening assignments, if any, and to the extent required in accordance with the foregoing, the assignment of the Mortgage to the Trustee to be submitted for recording promptly after the Closing Date; provided that the Seller need not cause to be recorded any assignment (a) in any jurisdiction under the laws of which, as evidenced by an Opinion of Counsel addressed to the Trustee delivered by the Seller to the Trustee and the Rating Agencies, the recordation of such assignment is not necessary to protect the Trustee’s interest in the related Mortgage Loan or (b) if MERS is identified on the Mortgage or on a properly recorded assignment of the Mortgage as mortgagee of record solely as nominee for Seller and its successors and assigns. In the event that the Seller, the Depositor or the Master Servicer gives written notice to the Trustee that a court has recharacterized the sale of the Mortgage Loans as a financing, the Seller shall submit or cause to be submitted for recording as specified above or, should the Seller fail to perform such obligations, the Master Servicer shall cause each such previously unrecorded assignment to be submitted for recording as specified above at the expense of the Trust. In the event a Mortgage File is released to the Company or the Servicer as a result of such Person having completed a Request for Release, the Custodian shall, if not so completed, complete the assignment of the related Mortgage in the manner specified in clause (iii) above.

In connection with the assignment of any Mortgage Loan registered on the MERS® System, the Seller further agrees that it will cause, at the Seller’s own expense, within 30 days after the Closing Date, the MERS® System to indicate that such Mortgage Loans have been assigned by the Seller to the Depositor and by the Depositor to the Trustee in accordance with this Agreement for the benefit of the Certificateholders by including (or deleting, in the case of Mortgage Loans which are repurchased in accordance with this Agreement) in such computer files (a) the code in the field which identifies the specific Trustee and (b) the code in the field “Pool Field” which identifies the series of the Certificates issued in connection with such Mortgage Loans. The Seller further agrees that it will not, and will not permit the Company, any Servicer or the Master Servicer to, and the Master Servicer agrees that it will not, alter the codes referenced in this paragraph with respect to any Mortgage Loan during the term of this Agreement unless and until such Mortgage Loan is repurchased in accordance with the terms of this Agreement or the Mortgage Loan Purchase Agreement.

Section 2.02

Acceptance of the Mortgage Loans.

(a) Based on the Initial Certification received by it from the Custodian, the Trustee acknowledges receipt of, subject to the further review and exceptions reported by the

Custodian pursuant to the procedures described below, the documents (or certified copies thereof) delivered to the Trustee or the Custodian on its behalf pursuant to Section 2.01 and declares that it holds and will continue to hold directly or through a custodian those documents and any amendments, replacements or supplements thereto and all other assets of the Trust Fund delivered to it in trust for the use and benefit of all present and future Holders of the Certificates. On the Closing Date, the Trustee or the Custodian on its behalf will deliver an Initial Certification confirming whether or not it has received the Mortgage File for each Mortgage Loan, but without review of such Mortgage File, except to the extent necessary to confirm whether such Mortgage File contains the original Mortgage Note or a lost note affidavit and indemnity in lieu thereof. No later than 90 days after the Closing Date, the Trustee or the Custodian on its behalf shall, for the benefit of the Certificateholders, review each Mortgage File delivered to it and execute and deliver to the Seller and, if reviewed by the Custodian, the Trustee, an Interim Certification. In conducting such review, the Trustee or the Custodian on its behalf will ascertain whether all required documents have been executed and received and whether those documents relate, determined on the basis of the Mortgagor name, original principal balance and loan number, to the Mortgage Loans identified in Exhibit B to this Agreement, as supplemented (provided, however, that with respect to those documents described in subclauses (iv) and (vi) of Section 2.01, such obligations shall extend only to documents actually delivered pursuant to such subclauses). In performing any such review, the Trustee and the Custodian may conclusively rely on the purported due execution and genuineness of any such document and on the purported genuineness of any signature thereon. If the Trustee or the Custodian on its behalf finds any document constituting part of the Mortgage File not to have been executed or received, or to be unrelated to the Mortgage Loans identified in Exhibit B or to appear to be defective on its face, the Trustee or the Custodian on its behalf shall include such information in the exception report. The Seller shall correct or cure any such defect or, if prior to the end of the second anniversary of the Closing Date, the Seller may substitute for the related Mortgage Loan a Replacement Mortgage Loan, which substitution shall be accomplished in the manner and subject to the conditions set forth in Section 2.03 or shall deliver to the Trustee an Opinion of Counsel addressed to the Trustee to the effect that such defect does not materially or adversely affect the interests of the Certificateholders in such Mortgage Loan within 60 days from the date of notice from the Trustee of the defect and if the Seller fails to correct or cure the defect or deliver such opinion within such period, the Seller will, subject to Section 2.03, within 90 days from the notification of the Trustee purchase such Mortgage Loan at the Purchase Price; provided, however, that if such defect relates solely to the inability of the Seller to deliver the Mortgage, assignment thereof to the Trustee, or intervening assignments thereof with evidence of recording thereon because such documents have been submitted for recording and have not been returned by the applicable jurisdiction, the Seller shall not be required to purchase such Mortgage Loan if the Seller delivers such documents promptly upon receipt, but in no event later than 360 days after the Closing Date.

(b) No later than 180 days after the Closing Date, the Trustee or the Custodian on its behalf will review, for the benefit of the Certificateholders, the Mortgage Files and will execute and deliver or cause to be executed and delivered to the Seller and, if reviewed by the Custodian, the Trustee, a Final Certification. In conducting such review, the Trustee or the Custodian on its behalf will ascertain whether each document required to be recorded has been returned from the recording office with evidence of recording thereon and the Trustee or the Custodian on its behalf has received either an original or a copy thereof, as required in Section

2.01 (provided, however, that with respect to those documents described in subclauses (iv) and (vi) of Section 2.01, such obligations shall extend only to documents actually delivered pursuant to such subclauses). If the Trustee or the Custodian on its behalf finds any document with respect to a Mortgage Loan has not been received, or to be unrelated, determined on the basis of the Mortgagor name, original principal balance and loan number, to the Mortgage Loans identified in Exhibit B or to appear defective on its face, the Trustee or the Custodian on its behalf shall note such defect in the exception report attached to the Final Certification and shall promptly notify the Seller. The Seller shall correct or cure any such defect or, if prior to the end of the second anniversary of the Closing Date, the Seller may substitute for the related Mortgage Loan a Replacement Mortgage Loan, which substitution shall be accomplished in the manner and subject to the conditions set forth in Section 2.03 or shall deliver to the Trustee an Opinion of Counsel addressed to the Trustee to the effect that such defect does not materially or adversely affect the interests of Certificateholders in such Mortgage Loan within 60 days from the date of notice from the Trustee of the defect and if the Seller is unable within such period to correct or cure such defect, or to substitute the related Mortgage Loan with a Replacement Mortgage Loan or to deliver such opinion, the Seller shall, subject to Section 2.03, within 90 days from the notification of the Trustee, purchase such Mortgage Loan at the Purchase Price; provided, however, that if such defect relates solely to the inability of the Seller to deliver the Mortgage, assignment thereof to the Trustee or intervening assignments thereof with evidence of recording thereon, because such documents have not been returned by the applicable jurisdiction, the Seller shall not be required to purchase such Mortgage Loan, if the Seller delivers such documents promptly upon receipt, but in no event later than 360 days after the Closing Date.

(c) In the event that a Mortgage Loan is purchased by the Seller in accordance with Subsections 2.02(a) or (b) above or Section 2.03, the Seller shall remit the applicable Purchase Price to the Master Servicer for deposit in the Master Servicer Collection Account and shall provide written notice to the Trustee detailing the components of the Purchase Price, signed by a Servicing Officer. Upon deposit of the Purchase Price in the Master Servicer Collection Account and upon receipt of a Request for Release with respect to such Mortgage Loan, the Trustee or the Custodian will release to the Seller the related Mortgage File and the Trustee shall execute and deliver all instruments of transfer or assignment, without recourse, representation or warranty furnished to it by the Seller, as are necessary to vest in the Seller title to and rights under the Mortgage Loan. Such purchase shall be deemed to have occurred on the date on which the deposit into the Master Servicer Collection Account was made. The Trustee shall promptly notify the Rating Agencies of such repurchase. The obligation of the Seller to cure, repurchase or substitute for any Mortgage Loan as to which a defect in a constituent document exists shall be the sole remedies respecting such defect available to the Certificateholders or to the Trustee on their behalf.

(d) The Seller shall deliver to the Trustee or the Custodian on its behalf, and Trustee agrees to accept the Mortgage Note and other documents constituting the Mortgage File with respect to any Replacement Mortgage Loan, which the Trustee or the Custodian will review as provided in Subsections 2.02(a) and 2.02(b), provided, that the Closing Date referred to therein shall instead be the date of delivery of the Mortgage File with respect to each Replacement Mortgage Loan.

The Seller hereby covenants with respect to the representations and warranties set forth in Section 7 of the Mortgage Loan Purchase Agreement, that within 90 days of the discovery of a breach of any representation or warranty set forth therein that materially and adversely affects the interests of the Certificateholders in any Mortgage Loan, it shall cure such breach in all material respects and, if such breach is not so cured, (i) if such 90-day period expires prior to the second anniversary of the Closing Date, remove such Mortgage Loan (a “Deleted Mortgage Loan”) from the Trust Fund and substitute in its place a Replacement Mortgage Loan, in the manner and subject to the conditions set forth in this Section; or (ii) repurchase the affected Mortgage Loan or Mortgage Loans from the Trustee at the Purchase Price in the manner set forth below; provided that any such substitution pursuant to (i) above or repurchase pursuant to (ii) above shall not be effected prior to the delivery to the Trustee of an Opinion of Counsel if required by Section 2.05 hereof and any such substitution pursuant to (i) above shall not be effected prior to the additional delivery to the Trustee of a Request for Release. The Seller shall promptly reimburse the Master Servicer and the Trustee for any expenses reasonably incurred by the

Master Servicer or the Trustee in respect of enforcing the remedies for such breach. To enable the Securities Administrator to amend the Mortgage Loan Schedule, the Seller shall, unless it cures such breach in a timely fashion pursuant to this Section 2.03, promptly notify the Securities Administrator whether it intends either to repurchase, or to substitute for, the Mortgage Loan affected by such breach. With respect to the representations and warranties in Section 7 of the Mortgage Loan Purchase Agreement that are made to the best of the Seller’s knowledge, if it is discovered by any of the Depositor, the Master Servicer, the Seller, the Securities Administrator or the Trustee that the substance of such representation and warranty is inaccurate and such inaccuracy materially and adversely affects the value of the related Mortgage Loan, notwithstanding the Seller’s lack of knowledge with respect to the substance of such representation or warranty, the Seller shall nevertheless be required to cure, substitute for or repurchase the affected Mortgage Loan in accordance with the foregoing.

With respect to any Replacement Mortgage Loan or Loans, the Seller shall deliver to the Trustee (or the Custodian on its behalf) for the benefit of the Certificateholders such documents and agreements as are required by Section 2.01. No substitution will be made in any calendar month after the Determination Date for such month. Scheduled Payments due with respect to Replacement Mortgage Loans in the Due Period related to the Distribution Date on which such proceeds are to be distributed shall not be part of the Trust Fund and will be retained by the Seller. For the month of substitution, distributions to Certificateholders will include the Scheduled Payment due on any Deleted Mortgage Loan for the related Due Period and thereafter the Seller shall be entitled to retain all amounts received in respect of such Deleted Mortgage Loan. The Securities Administrator shall amend the Mortgage Loan Schedule for the benefit of the Certificateholders to reflect the removal of such Deleted Mortgage Loan and the substitution of the Replacement Mortgage Loan or Loans and the Securities Administrator shall deliver the amended Mortgage Loan Schedule to the Trustee and the Custodian. Upon such substitution, the Replacement Mortgage Loan or Loans shall be subject to the terms of this Agreement in all respects, and the Seller shall be deemed to have made with respect to such Replacement Mortgage Loan or Loans, as of the date of substitution, the representations and warranties set forth in Section 7 of the Mortgage Loan Purchase Agreement with respect to such Mortgage Loan. Upon any such substitution and the deposit into the Master Servicer Collection Account of the amount required to be deposited therein in connection with such substitution as described in the following paragraph and receipt by the Trustee of a Request for Release for such Mortgage Loan, the Trustee or the Custodian shall release to the Seller the Mortgage File relating to such Deleted Mortgage Loan and held for the benefit of the Certificateholders and the Trustee shall execute and deliver at the Seller’s direction such instruments of transfer or assignment as have been prepared by the Seller, in each case without recourse, representation or warranty as shall be necessary to vest in the Seller, or its respective designee, title to the Trustee’s interest in any Deleted Mortgage Loan substituted for pursuant to this Section 2.03.

For any month in which the Seller substitutes one or more Replacement Mortgage Loans for a Deleted Mortgage Loan, the Master Servicer will determine the amount (if any) by which the aggregate principal balance of all the Replacement Mortgage Loans as of the date of substitution is less than the Stated Principal Balance (after application of the principal portion of the Scheduled Payment due in the month of substitution) of such Deleted Mortgage Loan. An amount equal to the aggregate of such deficiencies, described in the preceding sentence for any Distribution Date (such amount, the “Substitution Adjustment Amount”) shall be deposited into

the Master Servicer Collection Account, by the Seller delivering such Replacement Mortgage Loan on the Determination Date for the Distribution Date relating to the Prepayment Period during which the related Mortgage Loan became required to be purchased or replaced hereunder.

In the event that the Seller shall have repurchased a Mortgage Loan, the Purchase Price therefor shall be deposited into the Master Servicer Collection Account maintained by the Master Servicer, on the Determination Date for the Distribution Date in the month following the month during which the Seller became obligated to repurchase or replace such Mortgage Loan and upon such deposit of the Purchase Price, the delivery of an Opinion of Counsel if required by Section 2.05 and the receipt of a Request for Release, the Trustee or the Custodian shall release the related Mortgage File held for the benefit of the Certificateholders to the Seller, and the Trustee shall execute and deliver at such Person’s direction the related instruments of transfer or assignment prepared by the Seller, in each case without recourse, representation or warranty as shall be necessary to transfer title from the Trustee for the benefit of the Certificateholders and transfer the Trustee’s interest to the Seller to any Mortgage Loan purchased pursuant to this Section 2.03. It is understood and agreed that the obligation under this Agreement of the Seller to cure, repurchase or replace any Mortgage Loan as to which a breach has occurred and is continuing shall constitute the sole remedies against the Seller respecting such breach available to Certificateholders, the Depositor or the Trustee.

(e) The representations and warranties set forth in Section 2.03 hereof shall survive delivery of the respective Mortgage Loans and Mortgage Files to the Trustee or the Custodian for the benefit of the Certificateholders.

Section 2.04

Representations and Warranties of the Depositor.

The Depositor hereby represents and warrants to the Master Servicer, the Securities Administrator and the Trustee as follows, as of the date hereof and as of the Closing Date:

(i) The Depositor is duly organized and is validly existing as limited liability company in good standing under the laws of the State of Delaware and has full power and authority necessary to own or hold its properties and to conduct its business as now conducted by it and to enter into and perform its obligations under this Agreement.

(ii) The Depositor has the full power and authority to execute, deliver and perform, and to enter into and consummate the transactions contemplated by, this Agreement and has duly authorized, by all necessary action on its part, the execution, delivery and performance of this Agreement; and this Agreement, assuming the due authorization, execution and delivery hereof by the other parties hereto, constitutes a legal, valid and binding obligation of the Depositor, enforceable against the Depositor in accordance with its terms, subject, as to enforceability, to (i) bankruptcy, insolvency, reorganization, moratorium and other similar laws affecting creditors’ rights generally and (ii) general principles of equity, regardless of whether enforcement is sought in a proceeding in equity or at law.

(iii) The execution and delivery of this Agreement by the Depositor, the consummation of the transactions contemplated by this Agreement, and the fulfillment of or compliance with the terms hereof are in the ordinary course of business of the

Depositor and will not (A) result in a material breach of any term or provision of the organizational documents of the Depositor or (B) materially conflict with, result in a material breach, violation or acceleration of, or result in a material default under, the terms of any other material agreement or instrument to which the Depositor is a party or by which it may be bound or (C) constitute a material violation of any statute, order or regulation applicable to the Depositor of any court, regulatory body, administrative agency or governmental body having jurisdiction over the Depositor; and the Depositor is not in breach or violation of any material indenture or other material agreement or instrument, or in violation of any statute, order or regulation of any court, regulatory body, administrative agency or governmental body having jurisdiction over it which breach or violation may materially impair the Depositor’s ability to perform or meet any of its obligations under this Agreement.

(iv) No litigation is pending, or, to the best of the Depositor’s knowledge, threatened, against the Depositor that would materially and adversely affect the execution, delivery or enforceability of this Agreement or the ability of the Depositor to perform its obligations under this Agreement in accordance with the terms hereof.

(v) No consent, approval, authorization or order of any court or governmental agency or body is required for the execution, delivery and performance by the Depositor of, or compliance by the Depositor with, this Agreement or the consummation of the transactions contemplated hereby, or if any such consent, approval, authorization or order is required, the Depositor has obtained the same.

The Depositor hereby represents and warrants to the Trustee as of the Closing Date, following the transfer of the Mortgage Loans to it by the Seller, the Depositor had good title to the Mortgage Loans and the related Mortgage Notes were subject to no offsets, claims, defenses or counterclaims.

It is understood and agreed that the representations and warranties set forth in the immediately preceding paragraph shall survive delivery of the Mortgage Files to the Trustee or the Custodian for the benefit of the Certificateholders. Upon discovery by the Depositor or the Trustee of a breach of such representations and warranties, the party discovering such breach shall give prompt written notice to the others and to each Rating Agency.

Section 2.05 Delivery of Opinion of Counsel in Connection with Substitutions and Repurchases.

(a) Notwithstanding any contrary provision of this Agreement, with respect to any Mortgage Loan that is not in default or as to which default is not imminent, no repurchase or substitution pursuant to Sections 2.02 or 2.03 shall be made unless the Seller delivers to the Trustee and Securities Administrator an Opinion of Counsel, addressed to the Trustee and Securities Administrator, to the effect that such repurchase or substitution would not (i) result in the imposition of the tax on “prohibited transactions” of REMIC I or REMIC II or contributions after the Closing Date, as defined in Sections 860F(a)(2) and 860G(d) of the Code, respectively or (ii) cause any of REMIC I or REMIC II to fail to qualify as a REMIC at any time that any Certificates are outstanding. Any Mortgage Loan as to which repurchase or substitution was delayed pursuant to this paragraph shall be repurchased or the substitution therefor shall occur

(subject to compliance with Sections 2.02 or 2.03) upon the earlier of (a) the occurrence of a default or imminent default with respect to such Mortgage Loan and (b) receipt by the Trustee of an Opinion of Counsel addressed to the Trustee to the effect that such repurchase or substitution, as applicable, will not result in the events described in clause (i) or clause (ii) of the preceding sentence.

(b) Upon discovery by the Depositor, the Seller, the Custodian or the Master Servicer 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 promptly (and in any event within 5 Business Days of discovery) give written notice thereof to the other parties and the Trustee. In connection therewith, the Trustee, or the Custodian on its behalf, shall require the Seller, at the Seller’s option, to either (i) substitute, if the conditions in Section 2.03(c) with respect to substitutions are satisfied, a Replacement Mortgage Loan for the affected Mortgage Loan, or (ii) repurchase the affected Mortgage Loan within 90 days of such discovery in the same manner as it would a Mortgage Loan for a breach of representation or warranty contained in Section 2.03. The Trustee, or the Custodian on its behalf, shall reconvey to the Seller the Mortgage Loan to be released pursuant hereto (and the Custodian shall deliver the related Mortgage File) 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 contained in Section 2.03.

Section 2.06

Countersignature and Delivery of Certificates.

(a) The Trustee acknowledges the sale, transfer and assignment to it of the Trust Fund and, concurrently with such transfer and assignment, the Securities Administrator has executed, countersigned and delivered, to or upon the order of the Depositor, the Certificates in authorized denominations evidencing the entire ownership of the Trust Fund. The Trustee agrees to hold the Trust Fund and exercise the rights referred to above for the benefit of all present and future Holders of the Certificates and to perform the duties set forth in this Agreement in accordance with its terms.

(b) The Depositor, concurrently with the execution and delivery hereof, does hereby transfer, assign, set over and otherwise convey in trust to the Trustee without recourse all the right, title and interest of the Depositor in and to the REMIC I Regular Interests and the other assets of REMIC II for the benefit of the holders of the REMIC II Certificates. The Trustee acknowledges receipt of the REMIC I Regular Interests (which are uncertificated) and the other assets of REMIC II and declares that it holds and will hold the same in trust for the exclusive use and benefit of the holders of the REMIC II Certificates.

ARTICLE III

ADMINISTRATION AND SERVICING OF EMC MORTGAGE LOANS BY COMPANY

Section 3.01

The Company.

The Company shall service and administer the EMC Mortgage Loans in accordance with customary and usual standards of practice of prudent mortgage loan servicers in the respective states in which the related Mortgaged Properties are located. In connection with such servicing and administration, the Company shall have full power and authority, acting alone and/or through subservicers as provided in Section 3.03, to do or cause to be done any and all things that it may deem necessary or desirable in connection with such servicing and administration, including but not limited to, the power and authority, subject to the terms hereof (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 related Mortgaged Property and assumptions of the Mortgage Notes and related Mortgages (but only in the manner provided herein), (iii) to collect any Insurance Proceeds and other Liquidation Proceeds, and (iv) subject to Section 3.09, to effectuate foreclosure or other conversion of the ownership of the Mortgaged Property securing any EMC Mortgage Loan; provided that the Company shall take no action that is inconsistent with or prejudices the interests of the Trust Fund or the Certificateholders in any EMC Mortgage Loan or the rights and interests of the Depositor and the Trustee under this Agreement.

Without limiting the generality of the foregoing, the Company, in its own name or in the name of the Trust, the Depositor or the Trustee, is hereby authorized and empowered by the Trust, the Depositor and the Trustee, when the Company believes it appropriate in its reasonable judgment, to execute and deliver, on behalf of the Trustee, the Depositor, the Certificateholders or any of them, any and all instruments of satisfaction or cancellation, or of partial or full release or discharge and all other comparable instruments, with respect to the EMC Mortgage Loans, and with respect to the related Mortgaged Properties held for the benefit of the Certificateholders. The Company shall prepare and deliver to the Depositor and/or the Trustee such documents requiring execution and delivery by any or all of them as are necessary or appropriate to enable the Company to service and administer the EMC Mortgage Loans. Upon receipt of such documents, the Depositor and/or the Trustee shall execute such documents and deliver them to the Company.

In accordance with the standards of the first paragraph of this Section 3.01, the Company shall advance or cause to be advanced funds as necessary for the purpose of effecting the payment of taxes and assessments on the Mortgaged Properties relating to the EMC Mortgage Loans, which advances shall be reimbursable in the first instance from related collections from the Mortgagors pursuant to Section 5.04, and further as provided in Section 5.02. All costs incurred by the Company, if any, in effecting the timely payments of taxes and assessments on the Mortgaged Properties relating to the EMC Mortgage Loans and related insurance premiums shall not, for the purpose of calculating monthly distributions to the Certificateholders, be added to the Stated Principal Balance under the related EMC Mortgage Loans, notwithstanding that the terms of such Mortgage Loans so permit.

Section 3.02

Due-on-Sale Clauses; Assumption Agreements.

(a) Except as otherwise provided in this Section 3.02, when any property subject to a Mortgage has been or is about to be conveyed by the Mortgagor, the Company shall to the extent that it has knowledge of such conveyance, enforce any due-on-sale clause contained in any Mortgage Note or Mortgage, to the extent permitted under applicable law and governmental regulations, but only to the extent that such enforcement will not adversely affect or jeopardize coverage under any Required Insurance Policy. Notwithstanding the foregoing, the Company is not required to exercise such rights with respect to an EMC Mortgage Loan if the Person to whom the related Mortgaged Property has been conveyed or is proposed to be conveyed satisfies the terms and conditions contained in the Mortgage Note and Mortgage related thereto and the consent of the mortgagee under such Mortgage Note or Mortgage is not otherwise so required under such Mortgage Note or Mortgage as a condition to such transfer. In the event that the Company is prohibited by law from enforcing any such due-on-sale clause, or if coverage under any Required Insurance Policy would be adversely affected, or if nonenforcement is otherwise permitted hereunder, the Company is authorized, subject to Section 3.02(b), to take or enter into an assumption and modification agreement from or with the person to whom such property has been or is about to be conveyed, pursuant to which such person becomes liable under the Mortgage Note and, unless prohibited by applicable state law, the Mortgagor remains liable thereon, provided that the Mortgage Loan shall continue to be covered (if so covered before the Company enters such agreement) by the applicable Required Insurance Policies. The Company, subject to Section 3.02(b), is also authorized with the prior approval of the insurers under any Required Insurance Policies 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 Mortgagor and becomes liable under the Mortgage Note. Notwithstanding the foregoing, the Company shall not be deemed to be in default under this Section 3.02(a) by reason of any transfer or assumption that the Company reasonably believes it is restricted by law from preventing.

(b) Subject to the Company’s duty to enforce any due-on-sale clause to the extent set forth in Section 3.02(a), in any case in which a Mortgaged Property has been conveyed to a Person by a Mortgagor, and such Person is to enter into an assumption agreement or modification agreement or supplement to the Mortgage Note or Mortgage that requires the signature of the Trustee, or if an instrument of release signed by the Trustee is required releasing the Mortgagor from liability on the related EMC Mortgage Loan, the Company shall prepare and deliver or cause to be prepared and delivered to the Trustee for signature and shall direct, in writing, the Trustee to execute the assumption agreement with the Person to whom the Mortgaged Property is to be conveyed and such modification agreement or supplement to the Mortgage Note or Mortgage or other instruments as are reasonable or necessary to carry out the terms of the Mortgage Note or Mortgage or otherwise to comply with any applicable laws regarding assumptions or the transfer of the Mortgaged Property to such Person. In connection with any such assumption, no material term of the Mortgage Note (including, but not limited to, the Mortgage Rate, the amount of the Scheduled Payment and any other term affecting the amount or timing of payment on the EMC Mortgage Loan) may be changed. In addition, the substitute Mortgagor and the Mortgaged Property must be acceptable to the Company in accordance with its servicing standards as then in effect. The Company shall notify the Trustee that any such substitution or assumption agreement has been completed by forwarding to the

Trustee the original of such substitution or assumption agreement, which in the case of the original 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. Any fee collected by the Company for entering into an assumption or substitution of liability agreement will be retained by the Company as additional servicing compensation.

Section 3.03

Subservicers.

The Company shall perform all of its servicing responsibilities hereunder or may cause a subservicer to perform any such servicing responsibilities on its behalf, but the use by the Company of a subservicer shall not release the Company from any of its obligations hereunder and the Company shall remain responsible hereunder for all acts and omissions of each subservicer as fully as if such acts and omissions were those of the Company. The Company shall pay all fees of each subservicer from its own funds, and a subservicer’s fee shall not exceed the Servicing Fee payable to the Company hereunder.

At the cost and expense of the Company, without any right of reimbursement from its Protected Account, the Company shall be entitled to terminate the rights and responsibilities of a subservicer and arrange for any servicing responsibilities to be performed by a successor subservicer; provided, however, that nothing contained herein shall be deemed to prevent or prohibit the Company, at the Company’s option, from electing to service the related EMC Mortgage Loans itself. In the event that the Company’s responsibilities and duties under this Agreement are terminated pursuant to Section 9.03, the Company shall at its own cost and expense terminate the rights and responsibilities of each subservicer effective as of the date of termination of the Company. The Company shall pay all fees, expenses or penalties necessary in order to terminate the rights and responsibilities of each subservicer from the Company’s own funds without reimbursement from the Trust Fund.

Notwithstanding the foregoing, the Company shall not be relieved of its obligations hereunder and shall be obligated to the same extent and under the same terms and conditions as if it alone were servicing and administering the EMC Mortgage Loans. The Company shall be entitled to enter into an agreement with a subservicer for indemnification of the Company by the subservicer and nothing contained in this Agreement shall be deemed to limit or modify such indemnification.

Any subservicing agreement and any other transactions or services relating to the EMC Mortgage Loans involving a subservicer shall be deemed to be between such subservicer and the Company alone, and neither the Master Servicer nor the Trustee shall have any obligations, duties or liabilities with respect to such subservicer including any obligation, duty or liability of either the Master Servicer or the Trustee to pay such subservicer’s fees and expenses. For purposes of remittances to the Master Servicer pursuant to this Agreement, the Company shall be deemed to have received a payment on an EMC Mortgage Loan when a subservicer has received such payment.

Section 3.04 Documents, Records and Funds in Possession of Company To Be Held for Trustee.

Notwithstanding any other provisions of this Agreement, the Company shall transmit to the Trustee as required by this Agreement all documents and instruments in respect of an EMC Mortgage Loan coming into the possession of the Company from time to time and shall account fully to the Trustee for any funds received by the Company or that otherwise are collected by the Company as Liquidation Proceeds or Insurance Proceeds in respect of any such Mortgage Loan. All Mortgage Files and funds collected or held by, or under the control of, the Company in respect of any EMC Mortgage Loans, whether from the collection of principal and interest payments or from Liquidation Proceeds, including but not limited to, any funds on deposit in the Protected Account maintained by the Company, shall be held by the Company for and on behalf of the Trustee and shall be and remain the sole and exclusive property of the Trustee, subject to the applicable provisions of this Agreement. The Company also agrees that it shall not create, incur or subject any Mortgage File or any funds that are deposited in the Protected Account maintained by the Company or the Master Servicer Collection Account or in any Escrow Account, or any funds that otherwise are or may become due or payable to the Trustee for the benefit of the Certificateholders, to any claim, lien, security interest, judgment, levy, writ of attachment or other encumbrance, or assert by legal action or otherwise any claim or right of set off against any Mortgage File or any funds collected on, or in connection with, an EMC Mortgage Loan, except, however, that the Company shall be entitled to set off against and deduct from any such funds any amounts that are properly due and payable to the Company under this Agreement.

Section 3.05

Maintenance of Hazard Insurance.

The Company shall cause to be maintained, for each EMC Mortgage Loan, hazard insurance on buildings upon, or comprising part of, the Mortgaged Property against loss by fire, hazards of extended coverage and such other hazards as are customary in the area where the related Mortgaged Property is located with an insurer which is licensed to do business in the state where the related Mortgaged Property is located. Each such policy of standard hazard insurance shall contain, or have an accompanying endorsement that contains, a standard mortgagee clause. The Company shall also cause flood insurance to be maintained on property acquired upon foreclosure or deed in lieu of foreclosure of any EMC Mortgage Loan, to the extent described below. Pursuant to Section 5.01, any amounts collected by the Company under any such policies (other than the amounts to be applied to the restoration or repair of the related Mortgaged Property or property thus acquired or amounts released to the Mortgagor in accordance with the Company’s normal servicing procedures) shall be deposited in the Protected Account maintained by the Company. Any cost incurred by the Company in maintaining any such insurance shall not, for the purpose of calculating monthly distributions to the Certificateholders or remittances to the Trustee (or Securities Administrator on its behalf) for their benefit, be added to the principal balance of the Mortgage Loan, notwithstanding that the terms of the EMC Mortgage Loan so permit. Such costs shall be recoverable by the Company out of late payments by the related Mortgagor or out of Liquidation Proceeds to the extent permitted by Section 5.02. It is understood and agreed that no earthquake or other additional insurance is to be required of any Mortgagor or maintained on property acquired in respect of a Mortgage 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 is located at the time of origination of the related

EMC Mortgage Loan in a federally designated special flood hazard area and such area is participating in the national flood insurance program, the Company shall cause flood insurance to be maintained with respect to such EMC Mortgage Loan. Such flood insurance shall be in an amount equal to the least of (i) the Stated Principal Balance of the related EMC Mortgage Loan, (ii) minimum amount required to compensate for damage or loss on a replacement cost basis or (iii) the maximum amount of such insurance available for the related Mortgaged Property under the Flood Disaster Protection Act of 1973, as amended.

In the event that the Company shall obtain and maintain a blanket policy insuring against hazard losses on all of the EMC Mortgage Loans, it shall conclusively be deemed to have satisfied its obligations as set forth in the first sentence of this Section 3.05, it being understood and agreed that such policy may contain a deductible clause on terms substantially equivalent to those commercially available and maintained by comparable servicers. If such policy contains a deductible clause, the Company shall, in the event that there shall not have been maintained on the related Mortgaged Property a policy complying with the first sentence of this Section 3.05, and there shall have been a loss that would have been covered by such policy, deposit in the Protected Account maintained by the Company the amount not otherwise payable under the blanket policy because of such deductible clause. Such deposit shall be from the Company’s own funds without reimbursement therefor. In connection with its activities as administrator and servicer of the EMC Mortgage Loans, the Company agrees to present, on behalf of itself, the Depositor and the Trustee for the benefit of the Certificateholders, claims under any such blanket policy.

Section 3.06

Presentment of Claims and Collection of Proceeds.

The Company shall prepare and present on behalf of the Trustee and the Certificateholders all claims under the Insurance Policies relating to the EMC Mortgage Loans and take such actions (including the negotiation, settlement, compromise or enforcement of the insured’s claim) as shall be necessary to realize recovery under such Insurance Policies. Any proceeds disbursed to the Company in respect of such Insurance Policies shall be promptly deposited in the Protected Account maintained by the Company 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 EMC Mortgage Loan to the insurer under any applicable Insurance Policy need not be so deposited (or remitted).

Section 3.07

Maintenance of the Primary Mortgage Insurance Policies.

(a) The Company 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 Company would have been covered thereunder. The Company shall use its best efforts to keep in force and effect (to the extent that the EMC Mortgage Loan requires the Mortgagor to maintain such insurance), Primary Mortgage Insurance applicable to each EMC Mortgage Loan. The Company 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.

(b) The Company agrees to present on behalf of the Trustee and the Certificateholders, claims to the insurer under any Primary Mortgage Insurance Policies relating

to the EMC Mortgage Loans and, in this regard, to take such reasonable action as shall be necessary to permit recovery under any Primary Mortgage Insurance Policies respecting defaulted EMC Mortgage Loans. Pursuant to Section 5.01, any amounts collected by the Company under any Primary Mortgage Insurance Policies shall be deposited in the Protected Account maintained by the Company, subject to withdrawal pursuant to Section 5.02 hereof.

Section 3.08

Fidelity Bond, Errors and Omissions Insurance.

The Company shall maintain, at its own expense, a blanket fidelity bond and an errors and omissions insurance policy, with broad coverage with responsible companies on all officers, employees or other persons acting in any capacity with regard to the EMC Mortgage Loans and who handle funds, money, documents and papers relating to the EMC Mortgage Loans. The fidelity bond and errors and omissions insurance shall be in the form of the Mortgage Banker’s Blanket Bond and shall protect and insure the Company against losses, including forgery, theft, embezzlement, fraud, errors and omissions and negligent acts of such persons. Such fidelity bond shall also protect and insure the Company against losses in connection with the failure to maintain any insurance policies required pursuant to this Agreement and the release or satisfaction of an EMC Mortgage Loan which is not in accordance with Accepted Servicing Practices. No provision of this Section 3.08 requiring the fidelity bond and errors and omissions insurance shall diminish or relieve the Company from its duties and obligations as set forth in this Agreement. The minimum coverage under any such bond and insurance policy shall be at least equal to the corresponding amounts required by Accepted Servicing Practices. The Company shall deliver to the Master Servicer a certificate from the surety and the insurer as to the existence of the fidelity bond and errors and omissions insurance policy and shall obtain a statement from the surety and the insurer that such fidelity bond or insurance policy shall in no event be terminated or materially modified without thirty days prior written notice to the Master Servicer and the Trustee. The Company shall notify the Master Servicer and the Trustee within five business days of receipt of notice that such fidelity bond or insurance policy will be, or has been, materially modified or terminated. The Trustee for the benefit of the Certificateholders must be named as loss payees on the fidelity bond and as additional insured on the errors and omissions policy.

Section 3.09

Realization Upon Defaulted Mortgage Loans; Determination of Excess Liquidation Proceeds and Realized Losses; Repurchases of Certain Mortgage Loans.

(a) The Company shall use reasonable efforts to foreclose upon or otherwise comparably convert the ownership of properties securing such of the EMC Mortgage Loans as come into and continue in default and as to which no satisfactory arrangements can be made for collection of delinquent payments. In connection with such foreclosure or other conversion, the Company shall follow such practices and procedures as it shall deem necessary or advisable and as shall be normal and usual in its general mortgage servicing activities and the requirements of the insurer under any Required Insurance Policy; provided that the Company shall not be required to expend its own funds in connection with any foreclosure or towards the restoration of any property unless it shall determine (i) that such restoration and/or foreclosure will increase the proceeds of liquidation of the EMC Mortgage Loan after reimbursement to itself of such expenses and (ii) that such expenses will be recoverable to it through Insurance Proceeds or Liquidation Proceeds (respecting which it shall have priority for purposes of withdrawals from

the Protected Account maintained by the Company pursuant to Section 5.02). If the Company reasonably believes that Liquidation Proceeds with respect to any such EMC Mortgage Loan would not be increased as a result of such foreclosure or other action, such EMC Mortgage Loan will be charged-off and will become a Liquidated Loan. The Company will give notice of any such charge-off to the Trustee and the Securities Administrator. The Company shall be responsible for all other costs and expenses incurred by it in any such proceedings; provided that such costs and expenses shall be Servicing Advances and that it shall be entitled to reimbursement thereof from the proceeds of liquidation of the related Mortgaged Property, as contemplated in Section 5.02. If the Company has knowledge that a Mortgaged Property that the Company is contemplating acquiring in foreclosure or by deed- in-lieu of foreclosure is located within a one-mile radius of any site with environmental or hazardous waste risks known to the Company, the Company will, prior to acquiring the related Mortgaged Property, consider such risks and only take action in accordance with its established environmental review procedures.

With respect to any REO Property relating to an EMC Mortgage Loan, the deed or certificate of sale shall be taken in the name of the Trustee for the benefit of the Certificateholders (or the Trustee’s nominee on behalf of the Certificateholders). The Trustee’s name shall be placed on the title to such REO Property solely as the Trustee hereunder and not in its individual capacity. The Company shall ensure that the title to such REO Property references this Agreement and the Trustee’s capacity hereunder. Pursuant to its efforts to sell such REO Property, the Company shall either itself or through an agent selected by the Company protect and conserve such REO Property in the same manner and to such extent as is customary in the locality where such REO Property is located and may, incident to its conservation and protection of the interests of the Certificateholders, rent the same, or any part thereof, as the Company deems to be in the best interest of the Company and the Certificateholders for the period prior to the sale of such REO Property. The Company shall prepare for and deliver to the Trustee and the Securities Administrator a statement with respect to each such REO Property that has been rented showing the aggregate rental income received and all expenses incurred in connection with the management and maintenance of such REO Property at such times as is necessary to enable the Trustee to comply with the reporting requirements of the REMIC Provisions. The net monthly rental income, if any, from such REO Property shall be deposited in the Protected Account maintained by the Company no later than the close of business on each Determination Date. The Company shall perform the tax reporting and withholding related to foreclosures, abandonments and cancellation of indebtedness income as specified by Sections 1445, 6050J and 6050P of the Code by preparing and filing such tax and information returns, as may be required.

In the event that the Trust Fund acquires any Mortgaged Property as aforesaid or otherwise in connection with a default or imminent default on an EMC Mortgage Loan, the Company shall dispose of such Mortgaged Property prior to three years after its acquisition by the Trust Fund or, at the expense of the Trust Fund, request more than 60 days prior to the day on which such three-year period would otherwise expire, an extension of the three-year grace period unless the Trustee shall have been supplied with an Opinion of Counsel addressed to the Trustee (such opinion not to be an expense of the Trustee) to the effect that the holding by the Trust Fund of such Mortgaged Property subsequent to such three-year period will not result in the imposition of taxes on “prohibited transactions” of REMIC I or REMIC II as defined in Section 860F of the Code or cause either REMIC I or REMIC II 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). Notwithstanding any other provision of this Agreement, no Mortgaged Property acquired by the Trust Fund shall be rented (or allowed to continue to be rented) or otherwise used for the production of income by or on behalf of the Trust Fund in such a manner or pursuant to any terms that would (i) cause such Mortgaged Property to fail to qualify as “foreclosure property” within the meaning of Section 860G(a)(8) of the Code or (ii) subject any of REMIC I or REMIC II to the imposition of any federal, state or local income taxes on the income earned from such Mortgaged Property under Section 860G(c) of the Code or otherwise, unless the Company has agreed to indemnify and hold harmless the Trust Fund with respect to the imposition of any such taxes.

The decision of the Company to foreclose on a defaulted EMC Mortgage Loan shall be subject to a determination by the Company that the proceeds of such foreclosure would exceed the costs and expenses of bringing such a proceeding. The income earned from the management of any Mortgaged Properties acquired through foreclosure or other judicial proceeding, net of reimbursement to the Company for expenses incurred (including any property or other taxes) in connection with such management and net of unreimbursed Servicing Fees, Advances, Servicing Advances and any management fee paid or to be paid with respect to the management of such Mortgaged Property, shall be applied to the payment of principal of, and interest on, the related defaulted EMC Mortgage Loans (with interest accruing as though such Mortgage Loans were still current) and all such income shall be deemed, for all purposes in the Agreement, to be payments on account of principal and interest on the related Mortgage Notes and shall be deposited into the Protected Account maintained by the Company. To the extent the income received during a Prepayment Period is in excess of the amount attributable to amortizing principal and accrued interest at the related Mortgage Rate on the related EMC Mortgage Loan, such excess shall be considered to be a partial Principal Prepayment for all purposes hereof.

The Liquidation Proceeds from any liquidation of an EMC Mortgage Loan, net of any payment to the Company as provided above, shall be deposited in the Protected Account maintained by the Company on the next succeeding Determination Date following receipt thereof for distribution on the related Distribution Date, except that any Excess Liquidation Proceeds shall be retained by the Company as additional servicing compensation.

The proceeds of any Liquidated Loan, as well as any recovery resulting from a partial collection of Liquidation Proceeds or any income from an REO Property, will be applied in the following order of priority: first, to reimburse the Company for any related unreimbursed Servicing Advances and Servicing Fees, pursuant to Section 5.02 or this Section 3.09; second, to reimburse the Company for any unreimbursed Advances, pursuant to Section 5.02 or this Section 3.09; third, to accrued and unpaid interest (to the extent no Advance has been made for such amount) on the EMC Mortgage Loan or related REO Property, at the Net Mortgage Rate to the first day of the month in which such amounts are required to be distributed; and fourth, as a recovery of principal of the EMC Mortgage Loan.

(b) On each Determination Date, the Company shall determine the respective aggregate amounts of Excess Liquidation Proceeds and Realized Losses, if any, for the related Prepayment Period.

(c) The Company has no intent to foreclose on any EMC Mortgage Loan based on the delinquency characteristics as of the Closing Date; provided, that the foregoing

does not prevent the Company from initiating foreclosure proceedings on any date hereafter if the facts and circumstances of such EMC Mortgage Loans including delinquency characteristics in the Company’s discretion so warrant such action.

Section 3.10

Servicing Compensation.

As compensation for its activities hereunder, the Company shall be entitled to retain or withdraw from its Protected Account out of each payment of interest on an EMC Mortgage Loan included in the Trust Fund an amount equal to the Servicing Fee.

Additional servicing compensation in the form of any Excess Liquidation Proceeds, assumption fees, late payment charges, all Prepayment Interest Excess on any EMC Mortgage Loan, all income and gain net of any losses realized from Permitted Investments with respect to funds in or credited to the Protected Account maintained by the Company shall be retained by the Company to the extent not required to be deposited in the Protected Account maintained by the Company pursuant to Section 5.02. The Company shall be required to pay all expenses incurred by it in connection with its servicing activities hereunder (including payment of any premiums for hazard insurance, as required by Section 3.05 and maintenance of the other forms of insurance coverage required by Section 3.07) and shall not be entitled to reimbursement therefor except as specifically provided in Section 5.02.

EMC will be entitled to retain any Prepayment Interest Excess pursuant to Section 5.07(e).

Section 3.11

REO Property.

(a) In the event the Trust Fund acquires ownership of any REO Property in respect of any related EMC Mortgage Loan, the deed or certificate of sale shall be issued to the Trustee, or to its nominee, on behalf of the related Certificateholders. The Company shall sell any such REO Property as expeditiously as possible and in accordance with the provisions of this Agreement. Pursuant to its efforts to sell such REO Property, the Company shall protect and conserve such REO Property in the manner and to the extent required herein, in accordance with the REMIC Provisions.

(b) The Company shall deposit all funds collected and received in connection with the operation of any REO Property in respect of any EMC Mortgage Loan into the Protected Account maintained by the Company.

(c) The Company, upon the final disposition of any REO Property in respect of any EMC Mortgage Loan, shall be entitled to reimbursement for any related unreimbursed Advances, unreimbursed Servicing Advances or Servicing Fees from Liquidation Proceeds received in connection with the final disposition of such REO Property; provided, that any such unreimbursed Advances or Servicing Fees as well as any unpaid Servicing Fees may be reimbursed or paid, as the case may be, prior to final disposition, out of any net rental income or other net amounts derived from such REO Property.

Section 3.12

Liquidation Reports.

Upon the foreclosure of any Mortgaged Property relating to an EMC Mortgage Loan or the acquisition thereof by the Trust Fund pursuant to a deed-in-lieu of foreclosure, the Company shall submit a liquidation report to the Master Servicer containing such information as shall be mutually acceptable to the Company and the Master Servicer with respect to such Mortgaged Property.

If the indemnification provided for herein is unavailable or insufficient to hold harmless the Master Servicer, then the Company agrees that it shall contribute to the amount paid or payable by the Master Servicer as a result of the losses, claims, damages or liabilities of the Master Servicer in such proportion as is appropriate to reflect the relative fault of the Master Servicer on the one hand and the Company on the other in connection with a breach of the Company’s obligations under this Section 3.13(b).

Section 3.14

The Company at its expense shall cause a firm of independent public accountants which is a member of the American Institute of Certified Public Accountants to furnish not later than March 1, 2006 and not later than March 1 of each year thereafter a statement, in a form

ARTICLE IV

ADMINISTRATION AND MASTER SERVICING OF MORTGAGE LOANS BY MASTER SERVICER

Section 4.01 Master Servicer. The Master Servicer shall, beginning on the Closing Date, supervise, monitor and oversee the obligation of the Company and the related Servicer to service and administer their respective Mortgage Loans in accordance with the terms of this Agreement and the related Servicing Agreement and shall have full power and authority to do any and all things which it may deem necessary or desirable in connection with such master servicing and administration. In performing its obligations hereunder, the Master Servicer shall act in a manner consistent with Accepted Master Servicing Practices. Furthermore, the Master Servicer shall oversee and consult with the Company and the related Servicer as necessary from time-to-time to carry out the Master Servicer’s obligations hereunder, shall receive, review and evaluate all reports, information and other data provided to the Master Servicer by the Company and the related Servicer and shall cause the Company and related Servicer to perform and observe the covenants, obligations and conditions to be performed or observed by such Person under this Agreement and the related Servicing Agreement. The Master Servicer shall independently and separately monitor the Company and the related Servicer’s servicing activities with respect to each related Mortgage Loan, reconcile the results of such monitoring with such information provided in the previous sentence on a monthly basis and coordinate corrective adjustments to the Company’s, the related Servicer’s and Master Servicer’s records, and based on such reconciled and corrected information, the Master Servicer shall provide such information to the Securities Administrator as shall be necessary in order for it to prepare the statements specified in Section 6.06 and any other information and statements required hereunder. The Master Servicer shall reconcile the results of its Mortgage Loan monitoring with the actual remittances of the Company and each Servicer pursuant to this Agreement and the related Servicing Agreement.

The Trustee shall furnish the Company, the Servicers and the Master Servicer with any powers of attorney and other documents in form as provided to it necessary or appropriate to enable the Company, the Servicer and the Master Servicer to service and administer the related Mortgage Loans and REO Property.

The Trustee or the Custodian on its behalf and the Securities Administrator shall provide access to the records and documentation in possession of the Trustee or the Custodian on its behalf or the Securities Administrator regarding the related Mortgage Loans and REO Property and the servicing thereof to the Certificateholders, the FDIC, and the supervisory agents and examiners of the FDIC, such access being afforded only upon reasonable prior written request and during normal business hours at the office of the Trustee, the Custodian or the Securities Administrator; provided, however, that, unless otherwise required by law, neither the Trustee, the Custodian nor the Securities Administrator shall be required to provide access to such records and documentation if the provision thereof would violate the legal right to privacy of any Mortgagor. The Trustee, the Custodian and the Securities Administrator shall allow representatives of the above entities to photocopy any of the records and documentation and shall provide equipment for that purpose at a charge that covers the Trustee’s, the Custodian’s or the Securities Administrator’s actual costs.

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

Section 4.02 REMIC-Related Covenants. For as long as each REMIC shall exist, the Trustee and the Securities Administrator shall act in accordance herewith to assure continuing treatment of such REMIC as a REMIC, and the Trustee and the Securities Administrator shall comply with any directions of the Seller, the Company, the Servicers or the Master Servicer to assure such continuing treatment. In particular, the Trustee shall not (a) sell or permit the sale of all or any portion of the Mortgage Loans or of any investment of deposits in an Account unless such sale is as a result of a repurchase of the Mortgage Loans pursuant to this Agreement or the Trustee has received a REMIC Opinion addressed to the Trustee prepared at the expense of the Trust Fund; and (b) other than with respect to a substitution pursuant to the Mortgage Loan Purchase Agreement or Section 2.03 of this Agreement, as applicable, accept any contribution to any REMIC after the Startup Day without receipt of a REMIC Opinion.

Section 4.03 Monitoring of Company and Servicer. (a) The Master Servicer shall be responsible for reporting to the Trustee and the Seller the compliance by the Company and the related Servicer with its duties under this Agreement and the related Servicing Agreement. In the review of the Company’s and the related Servicer’s activities, the Master Servicer may rely upon an Officer’s Certificate of the Company and the related Servicer with regard to such Person’s compliance with the terms of this Agreement or the related Servicing Agreement. In the event that the Master Servicer, in its judgment, determines that the Company or the related Servicer should be terminated in accordance with this Agreement or the related Servicing Agreement, or that a notice should be sent pursuant to this Agreement or the related Servicing Agreement with respect to the occurrence of an event that, unless cured, would constitute grounds for such termination, the Master Servicer shall notify the Seller and the Trustee thereof and the Master Servicer shall issue such notice or take such other action as it deems appropriate.

(b) The Master Servicer, for the benefit of the Trustee and the Certificateholders, shall enforce the obligations of the Company under this Agreement and the related Servicer under the related Servicing Agreement, and shall, in the event that the Company or the related Servicer fails to perform its obligations in accordance with this Agreement or the related Servicing Agreement, subject to the preceding paragraph, terminate the rights and obligations of such Person thereunder and act as servicer of the related Mortgage Loans or to cause the Trustee to enter into a new Servicing Agreement with a successor Servicer selected by the Master Servicer; provided, however, it is understood and acknowledged by the parties hereto that there will be a period of transition (not to exceed 90 days) before the actual servicing functions can be fully transferred to such successor Servicer. Such enforcement, including, without limitation, the legal prosecution of claims, termination of the related Servicing Agreement 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. The Master Servicer shall pay the costs of such enforcement at its own expense, subject to its right of reimbursement pursuant

to the provisions of this Agreement or the related Servicing Agreement, provided that the Master Servicer shall not be required to prosecute or defend any legal action except to the extent that the Master Servicer shall have received reasonable indemnity for its costs and expenses in pursuing such action.

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

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

(e) If the Master Servicer acts as a servicer, it will not assume liability for the representations and warranties of the Company or the related Servicer, if any, that it replaces.

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 errors and omissions insurance policy and the fidelity bond shall be in such form and amount generally acceptable for entities serving as master servicers or trustees.

Section 4.05 Power to Act; Procedures. 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 hereof, 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 and the related Servicing Agreement, as applicable; provided, however, that the Master Servicer shall not (and, consistent with its responsibilities under

Section 4.03, shall not permit the Company or the related Servicer to) knowingly or intentionally take any action, or fail to take (or fail to cause to be taken) any action reasonably within its control and the scope of duties more specifically set forth herein, that, under the REMIC Provisions, if taken or not taken, as the case may be, may cause REMIC I or REMIC II 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 or REMIC II to fail to qualify as a REMIC or result in the imposition of a tax upon REMIC I or REMIC II, as the case may be. The Trustee shall furnish the Master Servicer, upon written request from a Servicing Officer, with any powers of attorney empowering the Master Servicer, the Company or the related Servicer to execute and deliver instruments of satisfaction or cancellation, or of partial or full release or discharge, and to foreclose upon or otherwise liquidate Mortgaged Property, and to appeal, prosecute or defend in any court action relating to the Mortgage Loans or the Mortgaged Property, in accordance with the related Servicing Agreement and this Agreement, and the Trustee shall execute and deliver such other documents, as the Master Servicer may request, to enable the Master Servicer to master service and administer the 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 misuse of any such powers of attorney by the Master Servicer, the Company or the related Servicer). 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 10.11 hereof. In the performance of its duties hereunder, the Master Servicer shall be an independent contractor and shall not, except in those instances where it is taking action 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 provided in this Agreement or the related Servicing Agreement, to the extent Mortgage Loans contain enforceable due-on-sale clauses, the Master Servicer shall cause the Company and the related Servicer to enforce such clauses in accordance with this Agreement or the related 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 related 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 related Servicing Agreement.

Section 4.07 Release of Mortgage Files. (a) Upon becoming aware of the payment in full of any Mortgage Loan, or the receipt by the Company or the related 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 Company or the related Servicer will, if required under the related Servicing Agreement (or if the Company or the related Servicer does not, the Master Servicer may), promptly furnish to the Custodian, on behalf of the Trustee, two copies of a certification substantially in the form of Exhibit G hereto signed by a Servicing Officer or in a mutually agreeable electronic format which will, in lieu of a signature on its face, originate from a Servicing Officer (which certification shall include a statement to the effect that

all amounts received in connection with such payment that are required to be deposited in the Protected Account maintained by the Company or the Servicer pursuant to Article V or by the related Servicer pursuant to the related Servicing Agreement have been or will be so deposited) and shall request that the Custodian, on behalf of the Trustee, deliver to the Company or the related Servicer the related Mortgage File. Upon receipt of such certification and request, the Custodian, on behalf of the Trustee, shall promptly release the related Mortgage File to the Company or the related Servicer and the Trustee and Custodian shall have no further responsibility with regard to such Mortgage File. Upon any such payment in full, the Company or 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, representation or warranty) 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 Protected Account.

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

Section 4.08 Documents, Records and Funds in Possession of Master Servicer, Company and Servicer To Be Held for Trustee.

(a) The Master Servicer shall transmit and the Company or the related Servicer (to the extent required by this Agreement or the related Servicing Agreement) shall transmit to the Trustee or Custodian such documents and instruments coming into the possession of such Person from time to time as are required by the terms hereof, or in the case of the related Servicer, the related Servicing Agreement, to be delivered to the Trustee or Custodian. Any funds received by the Master Servicer, the Company or by the related Servicer in respect of any Mortgage Loan or which otherwise are collected by the Master Servicer, the Company or by the related Servicer as Liquidation Proceeds or Insurance Proceeds in respect of any Mortgage Loan shall be held for the benefit of the Trustee and the Certificateholders subject to the Master Servicer’s right to retain or withdraw from the Master Servicer Collection Account, the Master Servicing Compensation and other amounts provided in this Agreement, and to the right of the

Company and the related Servicer to retain its Servicing Fee and other amounts as provided in this Agreement or the related Servicing Agreement. The Master Servicer shall, and (to the extent provided in this Agreement or the related Servicing Agreement) shall cause the Company and the related Servicer to, provide access to information and documentation regarding the Mortgage Loans to the Trustee, its agents and accountants at any time upon reasonable request and during normal business hours, and to Certificateholders that are savings and loan associations, banks or insurance companies, the Office of Thrift Supervision, the FDIC and the supervisory agents and examiners of such Office and Corporation or examiners of any other federal or state banking or insurance regulatory authority if so required by applicable regulations of the 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.

(b) All Mortgage Files and funds collected or held by, or under the control of, the Master Servicer, in respect of any Mortgage Loans, whether from the collection of principal and interest payments or from Liquidation Proceeds or Insurance Proceeds, shall be held by the Master Servicer for and on behalf of the Trustee and the Certificateholders and shall be and remain the sole and exclusive property of the Trustee; provided, however, that the Master Servicer, the Company and the related Servicer shall be entitled to setoff against, and deduct from, any such funds any amounts that are properly due and payable to the Master Servicer or such Servicer under this Agreement or the related Servicing Agreement.

Section 4.09

Standard Hazard Insurance and Flood Insurance Policies.

(a) For each Mortgage Loan, the Master Servicer shall enforce any obligation of the Company and the related Servicer under this Agreement or the related Servicing Agreement to maintain or cause to be maintained standard fire and casualty insurance and, where applicable, flood insurance, all in accordance with the provisions of this Agreement or the related Servicing Agreement. It is understood and agreed that such insurance shall be with insurers meeting the eligibility requirements set forth in this Agreement and the related Servicing Agreement and that no earthquake or other additional insurance is to be required of any Mortgagor or to be maintained on property acquired in respect of a defaulted loan, other than pursuant to such applicable laws and regulations as shall at any time be in force and as shall require such additional insurance.

(b) Pursuant to Sections 5.01, 5.04 and 5.05 any amounts collected by the Company, the Servicers or the Master Servicer, or by the Company or the Servicers, under any insurance policies (other than amounts to be applied to the restoration or repair of the property subject to the related Mortgage or released to the Mortgagor in accordance with this Agreement or the Servicing Agreements) shall be deposited by the Company in its Protected Account or by the related Servicer or the Master Servicer into the Master Servicer Collection Account, subject to withdrawal pursuant to Sections 5.02, 5.04, 5.05 and 5.07, as applicable. Any cost incurred by the Master Servicer, the Company or the related Servicer in maintaining any such insurance if the Mortgagor defaults in its obligation to do so shall be added to the amount owing under the Mortgage Loan where the terms of the Mortgage Loan so permit; provided, however, that the addition of any such cost shall not be taken into account for purposes of calculating the

distributions to be made to Certificateholders and shall be recoverable by the Master Servicer, the Company or the related Servicer pursuant to Sections 5.02, 5.04, 5.05 and 5.07, as applicable.

Section 4.10

Presentment of Claims and Collection of Proceeds.

The Master Servicer shall (to the extent provided in this Agreement and the related Servicing Agreement) cause the Company or the Servicer to, prepare and present on behalf of the Trustee and the Certificateholders all claims under the Insurance Policies and take such actions (including the negotiation, settlement, compromise or enforcement of the insured’s claim) as shall be necessary to realize recovery under such policies. Any proceeds disbursed to the Master Servicer (or disbursed to the Company or the related Servicer and remitted to the Master Servicer) in respect of such policies, bonds or contracts shall be promptly deposited in the Master Servicer Collection 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 4.11

Maintenance of the Primary Mortgage Insurance Policies.

(a) The Master Servicer shall not take, or permit the Company or the related Servicer (to the extent such action is prohibited under this Agreement or the related Servicing Agreement) to 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 Master Servicer, the Company or the related Servicer, would have been covered thereunder. The Master Servicer shall use its best reasonable efforts to cause the Company and the related Servicer (to the extent required under this Agreement and the related Servicing Agreement) 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 (including any LPMI Policy) in accordance with the provisions of this Agreement and the related Servicing Agreement, as applicable. The Master Servicer shall not, and shall not permit the Company or the related Servicer (to the extent required under this Agreement or the related Servicing Agreement) to, cancel or refuse to renew any such 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 and the related Servicing Agreement, as applicable.

(b) The Master Servicer agrees to cause the Company and the related Servicer (to the extent required under this Agreement and the related Servicing Agreement) 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.

Section 4.20

Optional Purchase of Certain Mortgage Loans.

With respect to any Mortgage Loans which as of the first day of a Fiscal Quarter is delinquent in payment by 90 days or more or is an REO Property, EMC shall have the right to purchase any Mortgage Loan from the Trust which becomes 90 days or more delinquent or becomes an REO Property at a price equal to the Repurchase Price; provided however (i) that such Mortgage Loan is still 90 days or more delinquent or is an REO Property as of the date of such purchase and (ii) this purchase option, if not theretofore exercised, shall terminate on the date prior to the last day of the related Fiscal Quarter. This purchase option, if not exercised, shall not be thereafter reinstated unless the delinquency is cured and the Mortgage Loan thereafter again becomes 90 days or more delinquent or becomes an REO Property, in which case the option shall again become exercisable as of the first day of the related Fiscal Quarter.

In addition, EMC shall, at its option, purchase any Mortgage Loan from the Trust if the first Due Date for such Mortgage Loan is subsequent to the Cut-off Date and the initial Monthly Payment is not made within thirty (30) days of such Due Date. Such purchase shall be made at a price equal to the Repurchase Price.

If at any time EMC remits to the Master Servicer a payment for deposit in the Master Servicer Collection Account covering the amount of the Repurchase Price for such a Mortgage Loan, and EMC provides to the Trustee a certification signed by a Servicing Officer stating that the amount of such payment has been deposited in the Master Servicer Collection Account, then the Trustee shall execute the assignment of such Mortgage Loan prepared and delivered to the

Trustee, at the request of EMC, without recourse, representation or warranty, to EMC which shall succeed to all the Trustee’s right, title and interest in and to such Mortgage Loan, and all security and documents relative thereto. Such assignment shall be an assignment outright and not for security. EMC will thereupon own such Mortgage, and all such security and documents, free of any further obligation to the Trustee or the Certificateholders with respect thereto.

ARTICLE V

ACCOUNTS

Section 5.01

Collection of Mortgage Loan Payments; Protected Account.

(a) The Company shall make reasonable efforts in accordance with customary and usual standards of practice of prudent mortgage lenders in the respective states in which the Mortgaged Properties related to the EMC Mortgage Loans are located to collect all payments called for under the terms and provisions of the EMC Mortgage Loans to the extent such procedures shall be consistent with this Agreement and the terms and provisions of any related Required Insurance Policy. Consistent with the foregoing, the Company may in its discretion (i) waive any late payment charge and (ii) extend the due dates for payments due on a Mortgage Note related to an EMC Mortgage Loan for a period not greater than 125 days. In the event of any such arrangement, the Company shall make Advances on the related EMC Mortgage Loan during the scheduled period in accordance with the amortization schedule of such EMC Mortgage Loan without modification thereof by reason of such arrangements, and shall be entitled to reimbursement therefor in accordance with Section 6.01. The Company shall not be required to institute or join in litigation with respect to collection of any payment (whether under a Mortgage, Mortgage Note or otherwise or against any public or governmental authority with respect to a taking or condemnation) if it reasonably believes that enforcing the provision of the Mortgage or other instrument pursuant to which such payment is required is prohibited by applicable law. In addition, if (x) an EMC Mortgage Loan is in default or default is imminent or (y) the Company delivers to the Trustee a certification addressed to the Trustee, based on the advice of counsel or certified public accountants, in either case, that have a national reputation with respect to taxation of REMICs, that a modification of such EMC Mortgage Loan will not result in the imposition of taxes on or disqualify any of REMIC I or REMIC II, the Company may, (A) amend the related Mortgage Note to reduce the Mortgage Rate applicable thereto, provided that such reduced Mortgage Rate shall in no event be lower than 5.00% with respect to any EMC Mortgage Loan and (B) amend any Mortgage Note related to an EMC Mortgage Loan to extend the maturity thereof.

In accordance with the standards of the first paragraph of Section 3.01, the Company shall not waive (or permit a sub-servicer to waive) any Prepayment Charge related to an EMC Mortgage Loan unless: (i) the enforceability thereof shall have been limited by bankruptcy, insolvency, moratorium, receivership and other similar laws relating to creditors’ rights generally, (ii) the enforcement thereof is illegal, or any local, state or federal agency has threatened legal action if the prepayment penalty is enforced, (iii) the collectability thereof shall have been limited due to acceleration in connection with a foreclosure or other involuntary payment or (iv) such waiver is standard and customary in servicing similar Mortgage Loans and relates to a default or a reasonably foreseeable default and would, in the reasonable judgment of the Company, maximize recovery of total proceeds taking into account the value of such Prepayment Charge and the related EMC Mortgage Loan. If a Prepayment Charge is waived, but does not meet the standards described above, then the Company is required to pay the amount of such waived Prepayment Charge, for the benefit of the Class P Certificates, by remitting such amount to the Master Servicer by the Remittance Date.

(b) The Company shall establish and maintain a Protected Account (which shall at all times be an Eligible Account) with a depository institution in the name of the Company for the benefit of the Trustee on behalf of the Certificateholders and designated “U.S. Bank National Association, in trust for registered Holders of Bear Stearns Asset Backed Securities I LLC, Asset-Backed Certificates Series 2005-AC4”. The Company shall deposit or cause to be deposited into the Protected Account on a daily basis within one Business Day of receipt, except as otherwise specifically provided herein, the following payments and collections remitted by subservicers or received by it in respect of the EMC Mortgage Loans subsequent to the Cut-off Date (other than in respect of principal and interest due on the EMC Mortgage Loans on or before the Cut-off Date) and the following amounts required to be deposited hereunder:

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

(ii) all payments on account of interest on the EMC Mortgage Loans net of the related Servicing Fee permitted under Section 3.10 and LPMI Fees, if any;

(iii) all Liquidation Proceeds and Insurance Proceeds with respect to any EMC Mortgage Loans, other than proceeds to be applied to the restoration or repair of the Mortgaged Property or released to the Mortgagor in accordance with the Company’s normal servicing procedures;

(iv) any amount required to be deposited by the Company pursuant to Section 5.01(c) in connection with any losses on Permitted Investments;

(v) any amounts required to be deposited by the Company pursuant to Section 3.05;

(vi)	any Prepayment Charges collected on the EMC Mortgage Loans; and
(vii)	any other amounts required to be deposited hereunder.

The foregoing requirements for remittance by the Company into the Protected 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 or assumption fees, if collected, need not be remitted by the Company. In the event that the Company shall remit any amount not required to be remitted and not otherwise subject to withdrawal pursuant to Section 5.02, it may at any time withdraw or direct the institution maintaining the Protected Account, to withdraw such amount from the Protected Account, any provision herein to the contrary notwithstanding. Such withdrawal or direction may be accomplished by delivering written notice thereof to the institution maintaining the Protected Account, that describes the amounts deposited in error in the Protected Account. The Company shall maintain adequate records with respect to all withdrawals made pursuant to this Section. All funds deposited in the Protected Account shall be held in trust for the Certificateholders until withdrawn in accordance with Section 5.02.

(c) The institution that maintains the Protected Account shall invest the funds in the Protected Account, in the manner directed by the Company, in Permitted Investments which shall mature not later than the Remittance Date and shall not be sold or disposed of prior

to its maturity. All such Permitted Investments shall be made in the name of the Trustee, for the benefit of the Certificateholders. All income and gain net of any losses realized from any such investment shall be for the benefit of the Company as servicing compensation and shall be remitted to it monthly as provided herein. The amount of any losses incurred in the Protected Account in respect of any such investments shall be deposited by the Company into the Protected Account, out of the Company’s own funds.

(d) The Company shall give at least 30 days advance notice to the Trustee, the Seller, the Master Servicer, each Rating Agency and the Depositor of any proposed change of location of the Protected Account prior to any change thereof.

Section 5.02

Permitted Withdrawals From the Protected Account.

(a) The Company may from time to time make withdrawals from the Protected Account for the following purposes:

(i) to pay itself (to the extent not previously paid to or withheld by the Company), as servicing compensation in accordance with Section 3.10, that portion of any payment of interest that equals the Servicing Fee for the period with respect to which such interest payment was made, and, as additional servicing compensation, those other amounts set forth in Section 3.10;

(ii) to reimburse the Company for Advances made by it with respect to the Mortgage Loans, provided, however, that the Company’s right of reimbursement pursuant to this subclause (ii) shall be limited to amounts received on particular EMC Mortgage Loan(s) (including, for this purpose, Liquidation Proceeds and Insurance Proceeds) that represent late recoveries of payments of principal and/or interest on such particular EMC Mortgage Loan(s) in respect of which any such Advance was made;

(iii) to reimburse the Company for any previously made portion of a Servicing Advance or an Advance made by the Company that, in the good faith judgment of the Company, will not be ultimately recoverable by it from the related Mortgagor, any related Liquidation Proceeds, Insurance Proceeds or otherwise (a “Nonrecoverable Advance”), to the extent not reimbursed pursuant to clause (ii) or clause (v);

(iv) to reimburse the Company from Insurance Proceeds for Insured Expenses covered by the related Insurance Policy;

(v) to pay the Company any unpaid Servicing Fees and to reimburse it for any unreimbursed Servicing Advances, provided, however, that the Company’s right to reimbursement for Servicing Advances pursuant to this subclause (v) with respect to any EMC Mortgage Loan shall be limited to amounts received on particular EMC Mortgage Loan(s) (including, for this purpose, Liquidation Proceeds, Insurance Proceeds and purchase and repurchase proceeds) that represent late recoveries of the payments for which such Servicing Advances were made;

(vi) to pay to the Seller, the Depositor or itself, as applicable, with respect to each EMC Mortgage Loan or property acquired in respect thereof that has been

purchased pursuant to Section 2.02, 2.03 or 4.20 of this Agreement, all amounts received thereon and not taken into account in determining the related Stated Principal Balance of such repurchased EMC Mortgage Loan;

(vii) to pay any expenses recoverable by the Company pursuant to Section 8.04 of this Agreement;

(viii) to withdraw pursuant to Section 5.01 any amount deposited in the Protected Account and not required to be deposited therein; and

(ix) to clear and terminate the Protected Account upon termination of this Agreement pursuant to Section 11.01 hereof.

In addition, no later than 1:00 p.m. Eastern time on the Remittance Date, the Company shall withdraw from the Protected Account and remit to the Master Servicer the amount required to be withdrawn therefrom pursuant to Section 5.05 hereof. With respect to any remittance received by the Master Servicer from EMC after the date on which such remittance was due, EMC shall pay to the Master Servicer interest on any such late remittance at an annual rate equal to the prime rate announced to be in effect from time to time as published as the average rate in The Wall Street Journal (Northeast Edition), plus two percentage points, but in no event greater than the maximum amount permitted by applicable law. Such interest shall be deposited in EMC’s Protected Account by EMC on the date such late payment is made and shall cover the period commencing with the day following the date on which such remittance was due and ending with the Business Day on which such remittance is made, both inclusive. Such interest shall be remitted along with the distribution payable on the next succeeding Remittance Date. The payment by EMC of any such interest shall not be deemed an extension of time for payment or a waiver of any Event of Default with respect to EMC.

The Company shall keep and maintain separate accounting, on a Mortgage Loan by Mortgage Loan basis, for the purpose of justifying any withdrawal from the Protected Account pursuant to subclauses (i), (ii), (iv), (v) and (vi) above. Prior to making any withdrawal from the Protected Account pursuant to subclause (iii), the Company shall deliver to the Trustee an Officer’s Certificate of a Servicing Officer indicating the amount of any previous Advance or Servicing Advance determined by the Company to be a Nonrecoverable Advance and identifying the related EMC Mortgage Loan(s), and their respective portions of such Nonrecoverable Advance.

With respect to each month, such loan accounting reports shall contain the following:

(including a separate breakdown of any Principal Prepayment, including the amount of any Prepayment Interest Shortfall);

With respect to each EMC Mortgage Loan, to the extent required by the related Mortgage Note, the Company shall establish and maintain one or more accounts (each, an “Escrow Account”) and deposit and retain therein all collections from the Mortgagors (or advances by the Company) for the payment of taxes, assessments, hazard insurance premiums or comparable items for the account of the Mortgagors. Nothing herein shall require the Company to compel a Mortgagor to establish an Escrow Account in violation of applicable law.

Withdrawals of amounts so collected from the Escrow Accounts may be made only to effect timely payment of taxes, assessments, hazard insurance premiums, condominium or PUD association dues, or comparable items, to reimburse the Company out of related collections for any payments made with respect to each EMC Mortgage Loan pursuant to Section 3.01 (with respect to taxes and assessments and insurance premiums) and Section 3.05 (with respect to hazard insurance), to refund to any Mortgagors for any EMC Mortgage Loans any sums as may be determined to be overages, to pay interest, if required by law or the terms of the related Mortgage or Mortgage Note, to such Mortgagors on balances in the Escrow Account or to clear and terminate the Escrow Account at the termination of this Agreement in accordance with Section 11.01 thereof. The Escrow Account shall not be a part of the Trust Fund.

Section 5.05 Servicer Protected Accounts. (a) The Master Servicer shall enforce the obligation of the Company and the Servicers to establish and maintain a Protected Account in accordance with this Agreement and the Servicing Agreements, with records to be kept with

respect thereto on a Mortgage Loan by Mortgage Loan basis, into which accounts shall be deposited within one Business Day (or as of such other time specified in the Servicing Agreements) of receipt all collections of principal and interest on any Mortgage Loan and with respect to any REO Property received by the Company or the related Servicer, including Principal Prepayments, Insurance Proceeds, Liquidation Proceeds, and advances made from the Company’s or such Servicer’s own funds (less servicing compensation as permitted by this Agreement or the related Servicing Agreement) and all other amounts to be deposited in the Protected Accounts. Each of the Company and the Servicers are hereby authorized to make withdrawals from and deposits to the related Protected Account for purposes required or permitted by this Agreement.

ARTICLE VI

DISTRIBUTIONS AND ADVANCES

Section 6.01

Advances.

(a) The Company shall make an Advance with respect to any EMC Mortgage Loan and deposit such Advance in the Master Servicer Collection Account no later than 1:00 p.m. Eastern time on the Remittance Date in immediately available funds. The Master Servicer shall cause the related Servicer to remit any such Advance required pursuant to the terms of the related Servicing Agreement. The Company or the related Servicer, as applicable, shall be obligated to make any such Advance only to the extent that such advance would not be a Nonrecoverable Advance. If the Company or the related Servicer shall have determined that it has made a Nonrecoverable Advance or that a proposed Advance or a lesser portion of such Advance would constitute a Nonrecoverable Advance, the Company or the related Servicer, as the case may be, shall deliver (i) to the Securities Administrator for the benefit of the Certificateholders funds constituting the remaining portion of such Advance, if applicable, and (ii) to the Depositor, the Master Servicer, each Rating Agency and the Trustee an Officer’s Certificate setting forth the basis for such determination.

In lieu of making all or a portion of such Advance from its own funds, the Company may (i) cause to be made an appropriate entry in its records relating to the Protected Account that any Amounts Held for Future Distribution has been used by the Company in discharge of its obligation to make any such Advance and (ii) transfer such funds from the Protected Account to the Distribution Account. Any funds so applied and transferred shall be replaced by the Company by deposit in the Distribution Account, no later than the close of business on the Remittance Date immediately preceding the Distribution Date on which such funds are required to be distributed pursuant to this Agreement.

The Company shall be entitled to be reimbursed from the Protected Account for all Advances of its own funds made pursuant to this Section as provided in Section 5.02. The obligation to make Advances with respect to any EMC Mortgage Loan shall continue until such EMC Mortgage Loan is paid in full or the related Mortgaged Property or related REO Property has been liquidated or until the purchase or repurchase thereof (or substitution therefor) from the Trust Fund pursuant to any applicable provision of this Agreement, except as otherwise provided in this Section 6.01.

(b) If the Scheduled Payment on a Mortgage Loan that was due on a related Due Date and is delinquent other than as a result of application of the Relief Act and for which the Company or the related Servicer was required to make an Advance pursuant to this Agreement or the related Servicing Agreement exceeds the amount deposited in the Master Servicer Collection Account which will be used for an Advance with respect to such Mortgage Loan, the Master Servicer will deposit in the Master Servicer Collection Account not later than the Distribution Account Deposit Date immediately preceding the related Distribution Date an amount equal to such deficiency, net of the Master Servicing Fee and the Servicing Fee for such Mortgage Loan except to the extent the Master Servicer determines any such Advance to be nonrecoverable from Liquidation Proceeds, Insurance Proceeds or future payments on the Mortgage Loan for which such Advance was made. Subject to the foregoing, the Master Servicer

shall continue to make such Advances through the date that the Company or the related Servicer is required to do so under this Agreement or the related Servicing Agreement, as applicable. If applicable, on the Distribution Account Deposit Date, the Master Servicer shall present an Officer’s Certificate to the Trustee (i) stating that the Master Servicer elects not to make an Advance in a stated amount and (ii) detailing the reason it deems the advance to be nonrecoverable.

Subject to and in accordance with the provisions of Article IX hereof, in the event the Master Servicer fails to make such Advance, then the Trustee, as Successor Master Servicer, shall be obligated to make such Advance, subject to the provisions of this Section 6.01.

Section 6.02

Compensating Interest Payments.

(a) In the event that there is a Prepayment Interest Shortfall arising from a voluntary Principal Prepayment in part or in full by the Mortgagor with respect to any EMC Mortgage Loan, the Company shall, to the extent of the Servicing Fee for such Distribution Date, deposit into the Master Servicer Collection Account, as a reduction of the Servicing Fee for such Distribution Date, no later than the close of business on the Remittance Date immediately preceding such Distribution Date, an amount equal to the Prepayment Interest Shortfall; and in case of such deposit, the Company shall not be entitled to any recovery or reimbursement from the Depositor, the Trustee, the Seller, the Master Servicer, the Securities Administrator, the Trust Fund or the Certificateholders.

(b) The Master Servicer shall cause each Servicer under the related Servicing Agreement to remit any required Compensating Interest Payments to the Master Servicer Collection Account on the Remittance Date.

(c) The Master Servicer shall be required to remit the amount of any such Prepayment Interest Shortfalls, to the extent of the Master Servicing Compensation for such Distribution Date, in the event the Company or the related Servicer is required to make such payment but fails to do so.

Section 6.03

In addition, notwithstanding the foregoing, on any Distribution Date after the Distribution Date on which the Certificate Principal Balance of a Class of Offered Certificates has been reduced to zero, that Class of Offered Certificates will be retired and will no longer be entitled to distributions, including distributions in respect of Unpaid Interest Shortfalls or Net WAC Rate Carryover Amounts.

(b) On each Distribution Date, all amounts representing Prepayment Charges in respect of the Mortgage Loans received during the related Prepayment Period and deposited in the Distribution Account will be withdrawn from the Distribution Account and distributed by the Securities Administrator in accordance with the Remittance Report to the Class P Certificates and shall not be available for distribution to the Holders of any other Class of Certificates. The payment of such Prepayment Charges shall not reduce the Certificate Principal Balance of the Class P Certificates.

(c) Subject to Section 11.02 hereof respecting the final distribution, on each Distribution Date the Securities Administrator shall make distributions to each Certificateholder of record on the preceding Record Date either by wire transfer in immediately available funds to the account of such Holder at a bank or other entity having appropriate facilities therefor, if (i) such Holder has so notified the Securities Administrator at least 5 Business Days prior to the related Record Date and (ii) such Holder shall hold Regular Certificates with aggregate principal denominations of not less than $1,000,000 or evidencing a Percentage Interest aggregating 10%

or more with respect to such Class or, if not, by check mailed by first class mail to such Certificateholder at the address of such Holder appearing in the Certificate Register. Notwithstanding the foregoing, but subject to Section 11.02 hereof respecting the final distribution, distributions with respect to Certificates registered in the name of a Depository shall be made to such Depository in immediately available funds.

(d) On or before 5:00 p.m. Eastern time on the fifth Business Day immediately preceding each Distribution Date, the Master Servicer shall deliver a report to the Securities Administrator in the form of a computer readable magnetic tape (or by such other means as the Master Servicer and the Securities Administrator may agree from time to time) containing such data and information, as agreed to by the Master Servicer and the Securities Administrator such as to permit the Securities Administrator to prepare the Monthly Statement to Certificateholders and to direct the Securities Administrator in writing to make the required distributions for the related Distribution Date (the “Remittance Report”). The Securities Administrator shall deliver a Remittance Report to the Trustee on or before 5:00 p.m. Eastern time on the Business Day immediately preceding each Distribution Date.

Section 6.05

Allocation of Realized Losses.

(a) On or prior to each Determination Date, the Master Servicer shall determine the amount of any Realized Loss in respect of each Mortgage Loan that occurred during the immediately preceding calendar month.

(b) The interest portion of Realized Losses shall be allocated to the Certificates (other than the Class P Certificates) as described in Section 1.02 hereof.

(c) The principal portion of all Realized Losses on the Mortgage Loans shall be allocated on each Distribution Date as follows: first, to Net Monthly Excess Cashflow as part of the payment of the Extra Principal Distribution Amount, second, in reduction of the Overcollateralization Amount, until reduced to zero; third, to the Class B-4 Certificates, until the Certificate Principal Balance thereof has been reduced to zero; fourth, to the Class B-3 Certificates, until the Certificate Principal Balance thereof has been reduced to zero; fifth, to the Class B-2 Certificates, until the Certificate Principal Balance thereof has been reduced to zero; sixth, to the Class B-1 Certificates, until the Certificate Principal Balance thereof has been reduced to zero; seventh, to the Class M-3 Certificates, until the Certificate Principal Balance thereof has been reduced to zero; eighth, to the Class M-2 Certificates, until the Certificate Principal Balance thereof has been reduced to zero; and ninth, to the Class M-1 Certificates, until the Certificate Principal Balance thereof has been reduced to zero. All such 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 the principal portion of Realized Losses to a Subordinate 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 the Class C Certificates shall be made

by reducing the amount otherwise payable in respect thereof pursuant to Section 6.04(a) clause third. No allocations of any Realized Losses shall be made to the Certificate Principal Balances of the Senior Certificates or the Class P Certificates.

All such 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.

Notwithstanding the foregoing, no such allocation of any Realized Loss shall be made on a Distribution Date to any Class of Subordinate Certificates to the extent that such allocation would result in the reduction of the aggregate Certificate Principal Balance of all the Certificates (other than the Class P Certificates) as of such Distribution Date, after giving effect to all distributions and prior allocations of Realized Losses on the Mortgage Loans on such date, to an amount less than the aggregate Stated Principal Balance of all of the Mortgage Loans as of the first day of the month of such Distribution Date (such limitation, the “Loss Allocation Limitation”). In addition in no event will the Certificate Principal Balance of any Subordinate Certificate be reduced more than once in respect of any particular amount both (i) allocable to such Certificate in respect of Realized Losses and (ii) payable as principal to the Holder of such Certificate from Remaining Excess Spread.

In addition, in the event that the Master Servicer receives any Subsequent Recoveries from the Company or the related Servicer, the Master Servicer shall deposit such funds into the Master Servicer Collection Account pursuant to Section 5.06. 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 of Subordinate 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 Subordinate Certificates pursuant to this Section 6.05 and not previously reimbursed to such Class of Subordinate Certificates with Net Monthly Excess Cashflow pursuant to clause third of Section 6.04(a); provided, however, to the extent that no reductions to a Certificate Principal Balance of any Class of Subordinate Certificates currently exists as the result of a prior allocation of a Realized Loss, such Subsequent Recoveries will be applied as Excess Spread. The amount of any remaining Subsequent Recoveries will be applied to sequentially increase the Certificate Principal Balance of the Subordinate Certificates, beginning with the Class of Subordinate Certificates with the next highest payment priority, up to the amount of such Realized Losses previously allocated to such Class of Subordinate Certificates pursuant to this Section 6.05 and not previously reimbursed to such Class of Subordinate Certificates with Net Monthly Excess Cashflow pursuant to clause third of Section 6.04(a). 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 Subordinate Certificate of such Class in accordance with its respective Percentage Interest.

(d) All Realized Losses on the Mortgage Loans shall be allocated on each Distribution Date to the following REMIC I Regular Interests in the specified percentages, as follows: first, to Uncertificated Accrued Interest payable to the REMIC I Regular Interest AA and REMIC I Regular Interest ZZ up to an aggregate amount equal to the REMIC I Interest Loss Allocation Amount, 98% and 2%, respectively; second, to the Uncertificated Principal Balances

of the REMIC I Regular Interest AA and REMIC I Regular Interest ZZ up to an aggregate amount equal to the REMIC I Principal Loss Allocation Amount, 98% and 2%, respectively; third, to the Uncertificated Principal Balances of REMIC I Regular Interest AA, REMIC I Regular Interest B-4 and REMIC I Regular Interest ZZ, 98%, 1% and 1%, respectively, until the Uncertificated Principal Balance of REMIC I Regular Interest B-4 has been reduced to zero; fourth, to the Uncertificated Principal Balances of REMIC I Regular Interest AA, REMIC I Regular Interest B-3 and REMIC I Regular Interest ZZ, 98%, 1% and 1%, respectively, until the Uncertificated Principal Balance of REMIC I Regular Interest B-3 has been reduced to zero; fifth, to the Uncertificated Principal Balances of REMIC I Regular Interest AA, REMIC I Regular Interest B-2 and REMIC I Regular Interest ZZ, 98%, 1% and 1%, respectively, until the Uncertificated Principal Balance of REMIC I Regular Interest B-2 has been reduced to zero; sixth, to the Uncertificated Principal Balances of REMIC I Regular Interest AA, REMIC I Regular Interest B-1 and REMIC I Regular Interest ZZ, 98%, 1% and 1%, respectively, until the Uncertificated Principal Balance of REMIC I Regular Interest B-1 has been reduced to zero; seventh, to the Uncertificated Principal Balances of REMIC I Regular Interest AA, REMIC I Regular Interest M-3 and REMIC I Regular Interest ZZ, 98%, 1% and 1%, respectively, until the Uncertificated Principal Balance of REMIC I Regular Interest M-3 has been reduced to zero; eighth, to the Uncertificated Principal Balances of REMIC I Regular Interest AA, REMIC I Regular Interest M-2 and REMIC I Regular Interest ZZ, 98%, 1% and 1%, respectively, until the Uncertificated Principal Balance of REMIC I Regular Interest M-2 has been reduced to zero; and ninth, to the Uncertificated Principal Balances of REMIC I Regular Interest AA, REMIC I Regular Interest M-1 and REMIC I Regular Interest ZZ, 98%, 1% and 1%, respectively, until the Uncertificated Principal Balance of REMIC I Regular Interest M-1 has been reduced to zero.

Section 6.07

REMIC Designations and REMIC I Distributions.

(a) The Trustee shall elect that each of REMIC I and REMIC II shall be treated as a REMIC under Section 860D of the Code. Any inconsistencies or ambiguities in this Agreement or in the administration of this Agreement shall be resolved in a manner that preserves the validity of such REMIC elections. The assets of REMIC I shall include the Mortgage Loans and all interest owing in respect of and principal due thereon, the Distribution Account, the Master Servicer Collection Account, the Protected Accounts maintained by the Company and the Servicers, any REO Property, any proceeds of the foregoing and any other assets subject to this Agreement (other than the Net WAC Reserve Fund). The REMIC I Regular Interests shall constitute the assets of REMIC II.

(b) On each Distribution Date, the Available Funds, in the following order of priority and in accordance with the Remittance Report, shall be deemed distributed by REMIC I to REMIC II on account of the REMIC I Regular Interests or withdrawn from the Distribution Account and distributed to the Holders of the Class R-1 Certificates, as the case may be:

(i) first, to the holders of REMIC I Regular Interest AA, REMIC Regular Interest A, REMIC I Regular Interest M-1, REMIC I Regular Interest M-2, REMIC I Regular Interest M-3, REMIC I Regular Interest B-1, REMIC I Regular Interest B-2, REMIC I Regular Interest B-3, REMIC I Regular Interest B-4 and REMIC I Regular Interest ZZ, pro rata, in an amount equal to (A) the Uncertificated Accrued Interest for each such REMIC I Regular Interest for such Distribution Date, plus (B) any amounts in respect thereof remaining unpaid from previous Distribution Dates. Amounts payable as Uncertificated Accrued Interest in respect of REMIC I Regular Interest ZZ shall be reduced and deferred when the REMIC I Overcollateralization Amount is less than the REMIC I Overcollateralization Target Amount by the lesser of (x) the amount of such difference and (y) the REMIC I Regular Interest ZZ Maximum Interest Deferral Amount, and such amount will be payable to the holders of REMIC I Regular Interest A, REMIC I Regular Interest M-1, REMIC I Regular Interest M-2, REMIC I Regular Interest M-3, REMIC I Regular Interest B-1, REMIC I Regular Interest B-2, REMIC I Regular Interest B-3 and REMIC I Regular Interest B-4 in the same proportion as the Overcollateralization Increase Amount is allocated to the Corresponding Certificates, respectively, and the Uncertificated Principal Balance of REMIC I Regular Interest ZZ shall be increased by such amount;

(ii) second, to the holders of REMIC I Regular Interests, in an amount equal to the remainder of the Available Funds for such Distribution Date after the distributions made pursuant to clause (i) above, allocated as follows:

(A) 98.00% of such remainder to the holders of REMIC I Regular Interest AA, until the Uncertificated Principal Balance of such REMIC I Regular Interest is reduced to zero;

(B) 2.00% of such remainder, first, to the holders of REMIC I Regular Interest A, REMIC I Regular Interest M-1, REMIC I Regular Interest M-2, REMIC I Regular Interest M-3, REMIC I Regular Interest B-1, REMIC I Regular Interest B-2, REMIC I Regular Interest B-3 and REMIC I Regular Interest B-4, in an aggregate amount equal to 1.00% of and in the same proportion as principal payments are allocated to the Corresponding Certificates, until the Uncertificated Principal Balances of such REMIC I Regular Interests are reduced to zero, and second, to the holders of REMIC I Regular Interest ZZ, such remainder, until the Uncertificated Principal Balance of such REMIC I Regular Interest is reduced to zero; then

(c) On each Distribution Date, all amounts representing Prepayment Charges deemed distributed in respect of Class P Certificates shall be deemed distributed in respect of REMIC I Regular Interest P, provided that such amounts shall not reduce the Uncertificated Principal Balance of REMIC I Regular Interest P. On the Distribution Date in June 2010, $100 shall be deemed distributed in respect of REMIC I Regular Interest P in reduction of the Uncertificated Principal Balance thereof.

Section 6.08

Net WAC Reserve Fund.

(a) The Securities Administrator shall establish a Net WAC Reserve Fund on behalf of the holders of the Offered Certificates. The Net WAC Reserve Fund must be an Eligible Account. The Net WAC Reserve Fund shall be entitled “Net WAC Reserve Fund, U.S. Bank National Association as Trustee for the benefit of Holders of Bear Stearns Asset Backed Securities I LLC, Asset-Backed Certificates, Series 2005-AC4, Class A, Class M-1, Class M-2, Class M-3, Class B-1, Class B-2, Class B-3 and Class B-4”. On the Closing Date, the Depositor will deposit, or cause to be deposited, into the Net WAC Reserve Fund $5,000. On each Distribution Date as to which there is a Net WAC Rate Carryover Amount payable to any Class of Certificates, the Securities Administrator shall, in accordance with the Remittance Report for such Distribution Date, deposit the amounts pursuant to paragraphs 9 through 16 of clause third of Section 6.04(a) into the Net WAC Reserve Fund, and the Securities Administrator has been directed by the Class C Certificateholder to distribute such amounts to the Holders of the Offered Certificates in the amounts and priorities set forth in clause third of Section 6.04(a).

(b) The Net WAC Reserve Fund is an “outside reserve fund” within the meaning of Treasury Regulation Section 1.860G-2(h) and shall be an asset of the Trust Fund but not an asset of any REMIC. The Trustee on behalf of the Trust shall be the nominal owner of the Net WAC Reserve Fund. The Class C Certificateholders shall be the beneficial owners of the Net WAC Reserve Fund, subject to the power of the Securities Administrator to transfer amounts under Section 6.04(a). Amounts in the Net WAC Reserve Fund shall be held either uninvested in a trust or deposit account of the Securities Administrator with no liability for interest or other compensation thereof or, at the direction of the Majority Class C Certificateholder, be invested in

Permitted Investments that mature no later than the Business Day prior to the next succeeding Distribution Date. All net income and gain from such investments shall be distributed to the Majority Class C Certificateholder not as a distribution in respect of any interest in any REMIC on such Distribution Date. All amounts earned on amounts on deposit in the Net WAC Reserve Fund shall be taxable to the Majority Class C Certificateholder. Any losses on such investments shall be deposited in the Net WAC Reserve Fund by the Majority Class C Certificateholder out of its own funds immediately as realized. In the event that the Majority Class C Certificateholder shall fail to provide investment instructions to the Securities Administrator, the amounts on deposit in the Net WAC Reserve Fund shall be held uninvested.

(c) For federal tax return and information reporting, the right of the Holders of the Offered Certificates to receive payments from the Net WAC Reserve Fund in respect of any Net WAC Rate Carryover Amount shall be assigned a value of zero.

Section 6.09 Class P Certificate Account. The Securities Administrator shall establish and maintain with itself a separate, segregated trust account titled “Bear Stearns Asset-Backed Securities I Trust 2005-AC4 Class P Certificate Account”. On the Closing Date, the Depositor will deposit, or cause to be deposited, in the Class P Certificate Account $100.00. The amount on deposit in the Class P Certificate Account shall be held uninvested. On the June 2010 Distribution Date, the Securities Administrator shall withdraw the amount on deposit in the Class P Certificate Account and remit such amount to the Holders of the Class P Certificates in reduction of the Certificate Principal Balance thereof.

The Certificates shall be executed by manual or facsimile signature on behalf of the Securities Administrator by an authorized officer. Certificates bearing the manual or facsimile signatures of individuals who were, at the time when such signatures were affixed, authorized to sign on behalf of the Securities Administrator shall bind the Securities Administrator, notwithstanding that such individuals or any of them have ceased to be so authorized prior to the authentication and delivery of such Certificates or did not hold such offices at the date of such authentication and delivery. No Certificate shall be entitled to any benefit under this Agreement, or be valid for any purpose, unless there appears on such Certificate the countersignature of the Securities Administrator by manual signature, and such countersignature upon any Certificate shall be conclusive evidence, and the only evidence, that such Certificate has been duly countersigned and delivered hereunder. All Certificates shall be dated the date of their countersignature. On the Closing Date, the Securities Administrator shall authenticate the Certificates to be issued at the written direction of the Depositor, or any affiliate thereof.

The Depositor shall provide, or cause to be provided, to the Securities Administrator on a continuous basis, an adequate inventory of Certificates to facilitate transfers.

Section 7.02 Certificate Register; Registration of Transfer and Exchange of Certificates.

(a) The Securities Administrator shall maintain, or cause to be maintained in accordance with the provisions of Section 7.09 hereof, a Certificate Register for the Trust Fund in which, subject to the provisions of Subsections (b) and (c) below and 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. Upon surrender for registration of Transfer of any Certificate, the Securities Administrator shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates of the same Class and of like aggregate Percentage Interest.

At the option of a Certificateholder, Certificates may be exchanged for other Certificates of the same Class in authorized denominations and evidencing the same aggregate Percentage Interest upon surrender of the Certificates to be exchanged at the office or agency of the Securities Administrator. Whenever any Certificates are so surrendered for exchange, the Securities Administrator shall execute, authenticate, and deliver the Certificates that the Certificateholder making the exchange is entitled to receive. Every Certificate presented or surrendered for registration of Transfer or exchange shall be accompanied by a written instrument of Transfer in form satisfactory to the Securities Administrator duly executed by the Holder thereof or his attorney duly authorized in writing.

No service charge to the Certificateholders shall be made for any registration of Transfer or exchange of Certificates, but 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 may be required.

All Certificates surrendered for registration of Transfer or exchange shall be canceled and subsequently destroyed by the Securities Administrator in accordance with the Securities Administrator’s customary procedures.

(b) No Transfer of a Private Certificate shall be made unless such Transfer is made pursuant to an effective registration statement under the Securities Act and any applicable state securities laws or is exempt from the registration requirements under the Securities Act and such state securities laws. In the event that a Transfer is to be made in reliance upon an exemption from the Securities Act and such laws, in order to assure compliance with the Securities Act and such laws, the Certificateholder desiring to effect such Transfer and such Certificateholder’s prospective transferee shall each certify to the Securities Administrator in writing the facts surrounding the Transfer in substantially the forms set forth in Exhibit D (the “Transferor Certificate”) and (x) deliver a letter in substantially the form of either Exhibit E (the “Investment Letter”) or Exhibit F (the “Rule 144A Letter”) or (y) there shall be delivered to the Securities Administrator an Opinion of Counsel addressed to the Securities Administrator that such Transfer may be made pursuant to an exemption from the Securities Act, which Opinion of Counsel shall not be an expense of the Depositor, the Seller, the Master Servicer, the Securities Administrator or the Trustee. The Depositor shall provide to any Holder of a Private Certificate and any prospective transferee designated by any such Holder, information regarding the related Certificates and the Mortgage Loans and such other information as shall be necessary to satisfy the condition to eligibility set forth in Rule 144A(d)(4) for Transfer of any such Certificate

without registration thereof under the Securities Act pursuant to the registration exemption provided by Rule 144A. The Securities Administrator and the Master Servicer shall cooperate with the Depositor in providing the Rule 144A information referenced in the preceding sentence, including providing to the Depositor such information regarding the Certificates, the Mortgage Loans and other matters regarding the Trust Fund as the Depositor shall reasonably request to meet its obligation under the preceding sentence. Each Holder of a Private Certificate desiring to effect such Transfer shall, and does hereby agree to, indemnify the Trustee, the Depositor, the Seller, the Securities Administrator and the Master Servicer against any liability that may result if the Transfer is not so exempt or is not made in accordance with such federal and state laws.

No Transfer of an ERISA Restricted Certificate shall be made unless either (i) the Master Servicer and the Securities Administrator shall have received a representation from the transferee of such Certificate acceptable to and in form and substance satisfactory to the Master Servicer and the Securities Administrator, to the effect that such transferee is not an employee benefit plan subject to Section 406 of ERISA and/or a plan subject to Section 4975 of the Code, or a Person acting on behalf of any such plan or using the assets of any such plan, or (ii) in the case of any such ERISA Restricted Certificate presented for registration in the name of an employee benefit plan subject to ERISA, or a plan subject to Section 4975 of the Code (or comparable provisions of any subsequent enactments), or a trustee of any such plan or any other person acting on behalf of any such plan, the Securities Administrator shall have received an Opinion of Counsel for the benefit of the Trustee, the Master Servicer and the Securities Administrator and on which they may rely, satisfactory to the Securities Administrator, to the effect that the purchase and holding of such ERISA Restricted Certificate is permissible under applicable law, will not constitute or result in the assets of the Trust being deemed to be “plan assets” under ERISA or the Code, will not result in any prohibited transactions under ERISA or Section 4975 of the Code and will not subject the Trustee, the Master Servicer, the Depositor or the Securities Administrator to any obligation in addition to those expressly undertaken in this Agreement, which Opinion of Counsel shall not be an expense of the Trustee, the Master Servicer, the Depositor or the Securities Administrator. Notwithstanding anything else to the contrary herein, any purported transfer of an ERISA Restricted Certificate to or on behalf of an employee benefit plan subject to Section 406 of ERISA and/or a plan subject to Section 4975 of the Code without the delivery of the Opinion of Counsel as described above shall be void and of no effect; provided that the restriction set forth in this sentence shall not be applicable if there has been delivered to the Securities Administrator an Opinion of Counsel meeting the requirements of clause (ii) of the first sentence of this paragraph. None of the Trustee, the Securities Administrator or the Master Servicer shall be required to monitor, determine or inquire as to compliance with the transfer restrictions with respect to any ERISA Restricted Certificate that is a Book-Entry Certificate, and none of the Trustee, the Securities Administrator or the Master Servicer shall have any liability for transfers of any such Book-Entry Certificates made through the book-entry facilities of any Depository or between or among participants of the Depository or Certificate Owners made in violation of the transfer restrictions set forth herein. None of the Trustee, the Securities Administrator or the Master Servicer shall be under any liability to any Person for any registration of transfer of any ERISA Restricted Certificate that is in fact not permitted by this Section 7.02(b) or for making any payments due on such Certificate to the Holder thereof or taking any other action with respect to such Holder under the provisions of this Agreement. The Trustee and the Securities Administrator shall each be entitled, but not obligated, to recover from any Holder of any ERISA Restricted Certificate that was in fact an

employee benefit plan subject to Section 406 of ERISA or a plan subject to Section 4975 of the Code or a Person acting on behalf of any such plan at the time it became a Holder or, at such subsequent time as it became such a plan or Person acting on behalf of such a plan, all payments made on such ERISA Restricted Certificate at and after either such time. Any such payments so recovered by the Trustee or the Securities Administrator shall be paid and delivered by the Trustee or the Securities Administrator to the last preceding Holder of such Certificate that is not such a plan or Person acting on behalf of a plan.

Each beneficial owner of a Subordinate Certificate or any interest therein shall be deemed to have represented, by virtue of its acquisition or holding of that certificate or interest therein, that either (i) it is not a Plan or investing with “Plan Assets”, (ii) it has acquired and is holding such certificate in reliance on the Exemption, and that it understands that there are certain conditions to the availability of the Exemption, including that the certificate must be rated, at the time of purchase, not lower than “BBB-“(or its equivalent) by S&P, Fitch Ratings or Moody’s, and the certificate is so rated or (iii) (1) it is an insurance company, (2) the source of funds used to acquire or hold the certificate or interest therein is an “insurance company general account,” as such term is defined in Prohibited Transaction Class Exemption (“PTCE”) 95-60, and (3) the conditions in Sections I and III of PTCE 95-60 have been satisfied.

(c) 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 the rights of each Person acquiring any Ownership Interest in a Residual Certificate are expressly subject to the following provisions:

(i) Each Person holding or acquiring any Ownership Interest in a Residual Certificate shall be a Permitted Transferee and shall promptly notify the Securities Administrator of any change or impending change in its status as a Permitted Transferee.

(ii) No Ownership Interest in a Residual Certificate may be registered on the Closing Date or thereafter transferred, and the Securities Administrator shall not register the Transfer of any Residual Certificate unless, in addition to the certificates required to be delivered to the Securities Administrator under subparagraph (b) above, the Securities Administrator shall have been furnished with an affidavit (a “Transfer Affidavit”) of the initial owner or the proposed transferee in the form attached hereto as Exhibit C.

(iii) Each Person holding or acquiring any Ownership Interest in a Residual Certificate shall agree (A) to obtain a Transfer Affidavit from any other Person to whom such Person attempts to Transfer its Ownership Interest in a Residual Certificate, (B) to obtain a Transfer Affidavit from any Person for whom such Person is acting as nominee, trustee or agent in connection with any Transfer of a Residual Certificate and (C) not to Transfer its Ownership Interest in a Residual Certificate or to cause the Transfer of an Ownership Interest in a Residual Certificate to any other Person if it has actual knowledge that such Person is not a Permitted Transferee.

(iv) Any attempted or purported Transfer of any Ownership Interest in a Residual Certificate in violation of the provisions of this Section 7.02(c) shall be absolutely null and void and shall vest no rights in the purported Transferee. If any

purported transferee shall become a Holder of a Residual Certificate in violation of the provisions of this Section 7.02(c), then the last preceding Permitted Transferee shall be restored to all rights as Holder thereof retroactive to the date of registration of Transfer of such Residual Certificate. The Trustee and 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 Section 7.02(b) and this Section 7.02(c) or for making any payments due on such Certificate to the Holder thereof or taking any other action with respect to such Holder under the provisions of this Agreement so long as the Transfer was registered after receipt of the related Transfer Affidavit. The Trustee and the Securities Administrator shall be entitled but not obligated to recover from any Holder of a Residual Certificate that was in fact not a Permitted Transferee at the time it became a Holder or, at such subsequent time as it became other than a Permitted Transferee, all payments made on such Residual Certificate at and after either such time. Any such payments so recovered by the Securities Administrator shall be paid and delivered by the Trustee to the last preceding Permitted Transferee of such Certificate.

(v) The Master Servicer shall make available within 60 days of written request from the Securities Administrator, all information necessary to compute any tax imposed under Section 860E(e) of the Code as a result of a Transfer of an Ownership Interest in a Residual Certificate to any Holder who is not a Permitted Transferee.

The restrictions on Transfers of a Residual Certificate set forth in this Section 7.02(c) shall cease to apply (and the applicable portions of the legend on a Residual Certificate may be deleted) with respect to Transfers occurring after delivery to the Securities Administrator of an Opinion of Counsel addressed to the Securities Administrator, which Opinion of Counsel shall not be an expense of the Trustee, the Securities Administrator, the Seller or the Master Servicer to the effect that the elimination of such restrictions will not cause REMIC I and/or REMIC II, as applicable, to fail to qualify as a REMIC at any time that the Certificates are outstanding or result in the imposition of any tax on the Trust Fund, a Certificateholder or another Person. Each Person holding or acquiring any ownership Interest in a Residual Certificate hereby consents to any amendment of this Agreement that, based on an Opinion of Counsel addressed to the Securities Administrator and furnished to the Securities Administrator, is reasonably necessary (a) to ensure that the record ownership of, or any beneficial interest in, a Residual Certificate is not transferred, directly or indirectly, to a Person that is not a Permitted Transferee and (b) to provide for a means to compel the Transfer of a Residual Certificate that is held by a Person that is not a Permitted Transferee to a Holder that is a Permitted Transferee.

(d) The preparation and delivery of all certificates and opinions referred to above in this Section 7.02 shall not be an expense of the Trust Fund, the Trustee, the Depositor, the Seller, the Securities Administrator or the Master Servicer.

Section 7.03

Mutilated, Destroyed, Lost or Stolen Certificates.

If (a) 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 (b) there is delivered to the Securities Administrator and the Securities Administrator such security or indemnity as may be required by them to save each of them harmless, then, in the absence of notice to the Securities Administrator

that such Certificate has been acquired by a bona fide 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 like Class, tenor and Percentage Interest. In connection with the issuance of any new Certificate under this Section 7.03, 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 7.03 shall constitute complete and indefeasible evidence of ownership in the Trust Fund, as if originally issued, whether or not the lost, stolen or destroyed Certificate shall be found at any time. All Certificates surrendered to the Securities Administrator under the terms of this Section 7.03 shall be canceled and destroyed by the Securities Administrator in accordance with its standard procedures without liability on its part.

Section 7.04

Persons Deemed Owners.

The Securities Administrator, the Trustee and any agent of the Securities Administrator or the Trustee may treat the person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in this Agreement and for all other purposes whatsoever, and neither the Securities Administrator, the Trustee nor any agent of the Securities Administrator or the Trustee shall be affected by any notice to the contrary.

Section 7.05

Access to List of Certificateholders’ Names and Addresses.

If three or more Certificateholders (a) request such information in writing from the Securities Administrator, (b) state that such Certificateholders desire to communicate with other Certificateholders with respect to their rights under this Agreement or under the Certificates, and (c) provide a copy of the communication that such Certificateholders propose to transmit or if the Depositor or the Master Servicer shall request such information in writing from the Securities Administrator, then the Securities Administrator shall, within ten Business Days after the receipt of such request, provide the Depositor, the Master Servicer or such Certificateholders at such recipients’ expense the most recent list of the Certificateholders of the Trust Fund held by the Securities Administrator, if any. The Depositor and every Certificateholder, by receiving and holding a Certificate, agree that the Securities Administrator shall not be held accountable by reason of the disclosure of any such information as to the list of the Certificateholders hereunder, regardless of the source from which such information was derived.

Section 7.06

Book-Entry Certificates.

The Regular Certificates, upon original issuance, shall be issued in the form of one or more typewritten Certificates representing the Book-Entry Certificates, to be delivered to the Depository by or on behalf of the Depositor. Such Certificates shall initially be registered on the Certificate Register in the name of the Depository or its nominee, and no Certificate Owner of such Certificates will receive a definitive certificate representing such Certificate Owner’s interest in such Certificates, except as provided in Section 7.08. Unless and until definitive, fully registered Certificates (“Definitive Certificates”) have been issued to the Certificate Owners of such Certificates pursuant to Section 7.08:

(a)	the provisions of this Section shall be in full force and effect;

(b) the Depositor, the Securities Administrator and the Trustee may deal with the Depository and the Depository Participants for all purposes (including the making of distributions) as the authorized representative of the respective Certificate Owners of such Certificates;

(c) registration of the Book-Entry Certificates may not be transferred by the Securities Administrator except to another Depository;

(d) the rights of the respective Certificate Owners of such Certificates shall be exercised only through the Depository and the Depository Participants and shall be limited to those established by law and agreements between the Owners of such Certificates and the Depository and/or the Depository Participants. Pursuant to the Depository Agreement, unless and until Definitive Certificates are issued pursuant to Section 7.08, the Depository will make book-entry transfers among the Depository Participants and receive and transmit distributions of principal and interest on the related Certificates to such Depository Participants;

(e) the Depository may collect its usual and customary fees, charges and expenses from its Depository Participants;

(f) the Securities Administrator may rely and shall be fully protected in relying upon information furnished by the Depository with respect to its Depository Participants; and

(g) to the extent that the provisions of this Section conflict with any other provisions of this Agreement, the provisions of this Section shall control.

For purposes of any provision of this Agreement requiring or permitting actions with the consent of, or at the direction of, Certificateholders evidencing a specified percentage of the aggregate unpaid principal amount of any Class of Certificates, such direction or consent may be given by Certificate Owners (acting through the Depository and the Depository Participants) owning Book-Entry Certificates evidencing the requisite percentage of principal amount of such Class of Certificates.

Section 7.07

Notices to Depository.

Whenever any notice or other communication is required to be given to Certificateholders of a Class with respect to which Book-Entry Certificates have been issued, unless and until Definitive Certificates shall have been issued to the related Certificate Owners, the Securities Administrator shall give all such notices and communications to the Depository.

Section 7.08

Definitive Certificates.

If, after Book-Entry Certificates have been issued with respect to any Certificates, (a) the Depositor or the Depository advises the Securities Administrator that the Depository is no longer willing or able to discharge properly its responsibilities under the Depository Agreement with respect to such Certificates and the Depositor is unable to locate a qualified successor, (b) the Depositor, at its sole option, advises the Securities Administrator that it elects to terminate the

book-entry system with respect to such Certificates through the Depository or (c) after the occurrence and continuation of an Event of Default, Certificate Owners of such Book-Entry Certificates having not less than 51% of the Voting Rights evidenced by any Class of Book-Entry Certificates advise the Securities Administrator and the Depository in writing through the Depository Participants that the continuation of a book-entry system with respect to Certificates of such Class through the Depository (or its successor) is no longer in the best interests of the Certificate Owners of such Class, then the Securities Administrator shall notify all Certificate Owners of such Certificates, through the Depository, of the occurrence of any such event and of the availability of Definitive Certificates to applicable Certificate Owners requesting the same. The Depositor shall provide the Securities Administrator with an adequate inventory of certificates to facilitate the issuance and transfer of Definitive Certificates. Upon surrender to the Securities Administrator of any such Certificates by the Depository, accompanied by registration instructions from the Depository for registration, the Securities Administrator shall countersign and deliver such Definitive Certificates. Neither the Depositor nor the Securities Administrator shall be liable for any delay in delivery of such instructions and each may conclusively rely on, and shall be protected in relying on, such instructions. Upon the issuance of such 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 such Definitive Certificates as Certificateholders hereunder.

Section 7.09

Maintenance of Office or Agency.

The Securities Administrator will maintain or cause to be maintained at its expense an office or offices or agency or agencies at Wells Fargo Bank, National Association, Sixth Street and Marquette Avenue, Minneapolis, Minnesota 55479 where Certificates may be surrendered for registration of transfer or exchange.

(b) Any Person into which the Depositor, the Company or the Master Servicer may be merged or consolidated, or any corporation resulting from any merger or consolidation to which the Depositor, the Company or the Master Servicer shall be a party, or any Person succeeding to the business of the Depositor, the Company or the Master Servicer, shall be the successor of the Depositor, the Company or the Master Servicer hereunder, without the execution or filing of any paper or further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding.

Section 8.03 Indemnification of the Trustee, the Master Servicer and the Securities Administrator.

(a) The Master Servicer agrees to indemnify the Indemnified Persons for, and to hold them harmless against, any loss, liability or expense (including reasonable legal fees and disbursements of counsel) incurred on their part that may be sustained in connection with, arising out of, or relating to, any claim or legal action (including any pending or threatened claim or legal action) relating to this Agreement, including the powers of attorney delivered pursuant to Sections 4.01 and 4.05 hereof, the Assignment Agreements, the Custodial Agreement or the Certificates (i) related to the Master Servicer’s failure to perform its duties in compliance with this Agreement (except as any such loss, liability or expense shall be otherwise reimbursable pursuant to this Agreement) or (ii) incurred by reason of the Master Servicer’s willful misfeasance, bad faith or gross negligence in the performance of duties hereunder or by reason of reckless disregard of obligations and duties hereunder, provided, in each case, that with respect to any such claim or legal action (or pending or threatened claim or legal action), the Trustee shall have given the Master Servicer and the Seller written notice thereof promptly after the Trustee shall have with respect to such claim or legal action knowledge thereof; provided, however that the failure to give such notice shall not relieve the Master Servicer of its indemnification obligations hereunder. This indemnity shall survive the resignation or removal of the Trustee, Master Servicer or the Securities Administrator and the termination of this Agreement.

(b) The Company agrees to indemnify the Indemnified Persons and to hold them harmless from and against any and all claims, losses, damages, penalties, fines, forfeitures, legal fees and related costs, judgments, and any other costs, fees and expenses that the Indemnified Persons may sustain in any way related to the failure of the Company to perform in any way its duties and service the EMC Mortgage Loans in strict compliance with the terms of this Agreement and for breach of any representation or warranty of the Company contained herein. The Company shall immediately notify the Master Servicer and the Trustee if a claim is made by a third party with respect to this Agreement or the EMC Mortgage Loans, assume (with the consent of the Master Servicer and the Trustee and with counsel reasonably satisfactory to the Master Servicer and the Trustee) the defense of any such claim and pay all expenses in connection therewith, including counsel fees, and promptly pay, discharge and satisfy any judgment or decree which may be entered against it or any Indemnified Person in respect of such claim but failure to so notify the Company shall not limit its obligations hereunder. The Company agrees that it will not enter into any settlement of any such claim without the consent of the Indemnified Persons unless such settlement includes an unconditional release of such Indemnified Persons from all liability that is the subject matter of such claim. The provisions of this Section 8.03(b) shall survive termination of this Agreement.

(c) The Seller will indemnify any Indemnified Person for any loss, liability or expense of any Indemnified Person not otherwise paid or covered pursuant to Subsections (a) or (b) above.

Section 8.04 Limitations on Liability of the Depositor, the Company, the Master Servicer and Others. Subject to the obligation of the Seller, the Company and the Master Servicer to indemnify the Indemnified Persons pursuant to Section 8.03:

(a) Neither the Depositor, the Company, the Master Servicer nor any of the directors, officers, employees or agents of the Depositor, the Company and the Master Servicer shall be under any liability to the Indemnified Persons, the Trust Fund or the Certificateholders for taking any action or for refraining from taking any action in good faith pursuant to this Agreement, or for errors in judgment; provided, however, that this provision shall not protect the Depositor, the Company, the Master Servicer or any such Person against any breach of warranties or representations made herein or any liability which would otherwise be imposed by reason of such Person’s willful misfeasance, bad faith or gross negligence in the performance of duties or by reason of reckless disregard of obligations and duties hereunder.

(b) The Depositor, the Company, the Master Servicer and any director, officer, employee or agent of the Depositor, the Company and the Master Servicer 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.

(c) The Depositor, the Company, the Master Servicer the Securities Administrator, the Trustee, the Custodian and any director, officer, employee or agent of the Depositor, the Company, the Master Servicer, the Securities Administrator, the Trustee or the Custodian shall be indemnified by the Trust and held harmless thereby against any loss, liability or expense (including reasonable legal fees and disbursements of counsel) incurred on their part that may be sustained in connection with, arising out of, or related to, any claim or legal action (including any pending or threatened claim or legal action) relating to this Agreement, the

Assignment Agreements, the Custodial Agreement, the Certificates or the Servicing Agreements (except with respect to the Master Servicer only, to the extent that the Master Servicer is indemnified by the Company under this Agreement or by the related Servicer under the related Servicing Agreement), other than (i) any such loss, liability or expense related to the Company’s or the Master Servicer’s failure to perform its respective duties in compliance with this Agreement (except as any such loss, liability or expense shall be otherwise reimbursable pursuant to this Agreement), or to the Custodian’s failure to perform its duties under the Custodial Agreement, or (ii) any such loss, liability or expense incurred by reason of the Company’s, the Master Servicer’s or the Custodian’s willful misfeasance, bad faith or gross negligence in the performance of duties hereunder or under the Custodial Agreement, as applicable, or by reason of reckless disregard of obligations and duties hereunder or under the Custodial Agreement, as applicable.

(d) Neither the Depositor, the Company nor the Master Servicer shall be under any obligation to appear in, prosecute or defend any legal action that is not incidental to its duties under this Agreement and that in its opinion may involve it in any expense or liability; provided, however, the Master Servicer may in its discretion, with the consent of the Trustee (which consent shall not be unreasonably withheld), undertake any such action which it may deem necessary or desirable with respect to this Agreement and the rights and duties of the parties hereto and the interests of the Certificateholders hereunder. In such event, the legal expenses and costs of such action and any liability resulting therefrom shall be expenses, costs and liabilities of the Trust Fund, and the Master Servicer shall be entitled to be reimbursed therefor out of the Master Servicer Collection Account as provided by Section 5.05. Nothing in this Subsection 8.04(d) shall affect the Master Servicer’s obligation to supervise, or to take such actions as are necessary to ensure, the servicing and administration of the Mortgage Loans pursuant to Subsection 4.01(a).

(e) In taking or recommending any course of action pursuant to this Agreement, unless specifically required to do so pursuant to this Agreement, the Master Servicer shall not be required to investigate or make recommendations concerning potential liabilities which the Trust might incur as a result of such course of action by reason of the condition of the Mortgaged Properties but shall give notice to the Trustee if it has notice of such potential liabilities.

(f) The Master Servicer shall not be liable for any acts or omissions of the Company or the Servicers, except as otherwise expressly provided herein.

Section 8.05 Master Servicer and Company Not to Resign. (a) Except as provided in Section 8.07, the Master Servicer shall not resign from the obligations and duties hereby imposed on it except (i) with the prior written consent of the Trustee (which consent shall not be unreasonably withheld) or (ii) upon a determination that any such duties hereunder are no longer permissible under applicable law and such impermissibility cannot be cured. Any such determination permitting the resignation of the Master Servicer shall be evidenced by an Opinion of Counsel to such effect, addressed to and delivered to, the Trustee. No such resignation by the Master Servicer shall become effective until EMC or the Trustee or a successor to the Master Servicer reasonably satisfactory to the Trustee shall have assumed the responsibilities and obligations of the Master Servicer in accordance with Section 9.02 hereof. The Trustee shall notify the Rating Agencies of the resignation of the Master Servicer.

(b) The Company shall not resign from the obligations and duties hereby imposed on it except (i) upon the assignment of its servicing duties with respect to all or a portion of the EMC Mortgage Loans to an institution that is a Fannie Mae and Freddie Mac approved seller/servicer in good standing that has a net worth of not less than $10,000,000 and with the prior written consent of the Master Servicer (which consent shall not be unreasonably withheld) or (ii) upon the determination that its duties hereunder are no longer permissible under applicable law and such incapacity cannot be cured by the Company. Any determination permitting the resignation of the Company shall be evidenced by an Opinion of Counsel to such effect addressed to and delivered, to the Master Servicer and the Trustee which Opinion of Counsel shall be in form and substance acceptable to the Master Servicer and the Trustee. No appointment of a successor to the Company shall be effective hereunder unless (a) the Rating Agencies have confirmed in writing that such appointment will not result in a downgrade, qualification or withdrawal of the then current ratings assigned to the Certificates, (b) such successor shall have represented that it is meets the eligibility criteria set forth in clause (i) above and (c) such successor has agreed to assume the obligations of the Company hereunder to the extent of the EMC Mortgage Loans to be serviced by such successor. The Company shall provide a copy of the written confirmation of the Rating Agencies and the agreement executed by such successor to the Master Servicer and the Trustee. No such resignation shall become effective until a Qualified Successor or the Master Servicer shall have assumed the Company’s responsibilities and obligations hereunder. The Company shall notify the Master Servicer, the Trustee and the Rating Agencies of the resignation of the Company or the assignment of all or a portion of its servicing duties hereunder in accordance with this Section 8.05.

Section 8.06 Successor Master Servicer. In connection with the appointment of any successor Master Servicer or the assumption of the duties of the Master Servicer, EMC or the Trustee may make such arrangements for the compensation of such successor master servicer out of payments on the Mortgage Loans as EMC or the Trustee and such successor master servicer shall agree. If the successor master servicer does not agree that such market value is a fair price, such successor master servicer shall obtain two quotations of market value from third parties actively engaged in the servicing of single-family mortgage loans. In no event shall the compensation of any successor master servicer exceed that permitted the Master Servicer without the consent of all of the Certificateholders.

Section 8.07 Sale and Assignment of Master Servicing. The Master Servicer may sell and assign its rights and delegate its duties and obligations in its entirety as Master Servicer under this Agreement and EMC may terminate the Master Servicer without cause and select a new Master Servicer; provided, however, that: (i) the purchaser or transferee accepting such assignment and delegation (a) shall be a Person which (or an Affiliate thereof the primary business of which is the servicing of conventional residential mortgage loans) shall be qualified to service mortgage loans for Fannie Mae or Freddie Mac; (b) shall have a net worth of not less than $10,000,000 (unless otherwise approved by each Rating Agency pursuant to clause (ii) below); (c) shall be reasonably satisfactory to the Trustee (as evidenced in a writing signed by the Trustee); and (d) 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; (iii) the Master Servicer assigning and selling the master servicing shall deliver to the Trustee an Officer’s Certificate and an Opinion of Counsel addressed to the Trustee, 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; and (iv) in the event the Master Servicer is terminated without cause by EMC, EMC shall pay, from its own funds and without any right of reimbursement, the terminated Master Servicer a termination fee equal to 0.25% of the aggregate Stated Principal Balance of the Mortgage Loans at the time the master servicing of the Mortgage Loans is transferred to the successor Master Servicer. No such assignment or delegation shall affect any liability of the Master Servicer arising prior to the effective date thereof.

DEFAULT; TERMINATION OF MASTER SERVICER;

TERMINATION OF COMPANY

Section 9.01

Events of Default.

“Event of Default,” wherever used herein, means any one of the following events:

(i) any failure by the Master Servicer to remit to the Securities Administrator any amounts received or collected by the Master Servicer in respect of the Mortgage Loans and required to be remitted by it hereunder or any Advance required to be made by it pursuant to this Agreement, which failure shall continue unremedied for one Business Day after the date on which written notice of such failure shall have been given to the Master Servicer by the Trustee or the Depositor, or to the Trustee and the Master Servicer by the Holders of Certificates evidencing not less than 25% of the Voting Rights evidenced by the Certificates; or

(ii) any failure by the Master Servicer 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 any breach of a representation or warranty by the Master Servicer, which failure or breach shall continue unremedied for a period of 60 days after the date on which written notice of such failure shall have been given to Master Servicer by the Trustee or the Depositor, or to the Trustee and the Master Servicer by the Holders of Certificates evidencing not less than 25% of the Voting Rights evidenced by the Certificates; or

(iii) a decree or order of a court or agency or supervisory authority having jurisdiction in the premises for the appointment of a receiver or liquidator in any insolvency, readjustment of debt, marshalling of assets and liabilities or similar proceedings, or for the winding-up or liquidation of its affairs, shall have been entered against the Master Servicer and such decree or order shall have remained in force undischarged or unstayed for a period of 60 consecutive days; or

(iv) the Master Servicer shall consent to the appointment of a receiver or liquidator in any insolvency, readjustment of debt, marshalling of assets and liabilities or similar proceedings of or relating to the Master Servicer or all or substantially all of the property of the Master Servicer; or

(v) the Master Servicer shall admit in writing its inability to pay its debts generally as they become due, file a petition to take advantage of, or commence a voluntary case under, any applicable insolvency or reorganization statute, make an assignment for the benefit of its creditors, or voluntarily suspend payment of its obligations; or

(vi) the Master Servicer assigns or delegates its duties or rights under this Agreement in contravention of the provisions permitting such assignment or delegation under Sections 8.05 or 8.07.

If an Event of Default shall occur, then, and in each and every such case, so long as such Event of Default shall not have been remedied, the Trustee may, and at the direction of the Holders of Certificates evidencing not less than 25% of the Voting Rights evidenced by the Certificates, the Trustee shall, by notice in writing to the Master Servicer, with a copy to the Rating Agencies, and with the consent of the Company, may terminate all of the rights and obligations (but not the liabilities) of the Master Servicer (and the Securities Administrator if the Master Servicer and the Securities Administrator are the same entity) under this Agreement and in and to the Mortgage Loans and the proceeds thereof, other than its rights as a Certificateholder hereunder. On or after the receipt by the Master Servicer of such written notice, all authority and power of the Master Servicer (and, if applicable, the Securities Administrator) hereunder, whether with respect to the Mortgage Loans or otherwise, shall pass to and be vested in the Trustee, or any successor appointed pursuant to Section 9.02 (a “Successor Master Servicer” and, if applicable, “Successor Securities Administrator”). Such Successor Master Servicer shall thereupon if such Successor Master Servicer is a successor to the Master Servicer, make any Advance required by Article VI, subject, in the case of the Trustee, to Section 9.02. The Trustee is hereby authorized and empowered to execute and deliver, on behalf of the terminated Master Servicer and, if applicable, the terminated Securities Administrator, as attorney- in-fact or otherwise, any and all documents and other instruments, and to do or accomplish all other acts or things necessary or appropriate to effect the purposes of such notice of termination, whether to complete the transfer and endorsement or assignment of any Mortgage Loans and related documents, or otherwise. Unless expressly provided in such written notice, no such termination shall affect any obligation of the Master Servicer to pay amounts owed pursuant to Article VIII or Article X. The Master Servicer and, if applicable, the Securities Administrator agrees to cooperate with the Trustee in effecting the termination of the Master Servicer’s and, if applicable, the Securities Administrator’s responsibilities and rights hereunder, including, without limitation, the transfer to the applicable Successor Master Servicer of all cash amounts which shall at the time be credited to the Master Servicer Collection Account maintained pursuant to Section 5.06, or thereafter be received with respect to the applicable Mortgage Loans. The Trustee shall promptly notify the Rating Agencies of the occurrence of an Event of Default known to the Trustee.

Notwithstanding any termination of the activities of the Master Servicer hereunder, the Master Servicer shall be entitled to receive, out of any late collection of a Scheduled Payment on a Mortgage Loan that was due prior to the notice terminating the Master Servicer’s rights and obligations as Master Servicer hereunder and received after such notice, that portion thereof to which the Master Servicer would have been entitled pursuant to Sections 5.05 and to receive any other amounts payable to the Master Servicer hereunder the entitlement to which arose prior to the termination of its activities hereunder.

Section 9.02

Trustee to Act; Appointment of Successor.

On and after the time the Master Servicer receives a notice of termination pursuant to Section 9.01 hereof the Trustee shall automatically become the successor to the Master Servicer with respect to the transactions set forth or provided for herein and after a transition period (not to exceed 90 days), shall be subject to all the responsibilities, duties and liabilities relating thereto placed on the Master Servicer by the terms and provisions hereof; provided, however, that the Company shall have the right to either (a) immediately assume the duties of the Master Servicer or (b) select a successor Master Servicer; provided, further, however that, pursuant to

Article VI hereof, the Trustee in its capacity as successor Master Servicer shall be responsible for making any Advances required to be made by the Master Servicer immediately upon the termination of the Master Servicer and any such Advance shall be made on the Distribution Date on which such Advance was required to be made by the predecessor Master Servicer. Effective on the date of such notice of termination, as compensation therefor, the Trustee shall be entitled to all compensation, reimbursement of expenses and indemnifications that the Master Servicer would have been entitled to if it had continued to act hereunder, provided, however, that the Trustee shall not be (i) liable for any acts or omissions of the Master Servicer, (ii) obligated to make Advances if it is prohibited from doing so under applicable law, (iii) responsible for expenses of the Master Servicer pursuant to Section 2.03 or (iv) obligated to deposit losses on any Permitted Investment directed by the Master Servicer. Notwithstanding the foregoing, the Trustee may, if it shall be unwilling to so act, or shall, if it is prohibited by applicable law from making Advances pursuant to Article VI or if it is otherwise unable to so act, appoint, or petition a court of competent jurisdiction to appoint, any established mortgage loan servicing institution the appointment of which does not adversely affect the then current rating of the Certificates by each Rating Agency as the successor to the Master Servicer hereunder in the assumption of all or any part of the responsibilities, duties or liabilities of the Master Servicer hereunder. Any Successor Master Servicer shall (i) be an institution that is a Fannie Mae and Freddie Mac approved seller/servicer in good standing, that has a net worth of at least $15,000,000 and (ii) be willing to act as successor servicer of any Mortgage Loans under this Agreement or the related Servicing Agreement with respect to which the Company or the original Servicer has been terminated as servicer, and shall have executed and delivered to the Depositor and the Trustee an agreement accepting such delegation and assignment, that contains an assumption by such Person of the rights, powers, duties, responsibilities, obligations and liabilities of the Master Servicer (other than any liabilities of the Master Servicer hereof incurred prior to termination of the Master Servicer under Section 9.01 or as otherwise set forth herein), with like effect as if originally named as a party to this Agreement, provided that each Rating Agency shall have acknowledged in writing that its rating of the Certificates in effect immediately prior to such assignment and delegation will not be qualified or reduced as a result of such assignment and delegation. If the Trustee assumes the duties and responsibilities of the Master Servicer in accordance with this Section 9.02, the Trustee shall not resign as Master Servicer until a Successor Master Servicer has been appointed and has accepted such appointment. Pending appointment of a successor to the Master Servicer hereunder, the Trustee, unless the Trustee is prohibited by law from so acting, shall, subject to Section 4.04 hereof, act in such capacity as hereinabove provided. In connection with such appointment and assumption, the Trustee may make such arrangements for the compensation of such successor out of payments on Mortgage Loans or otherwise as it and such successor shall agree; provided that no such compensation unless agreed to by the Certificateholders shall be in excess of that permitted the Master Servicer hereunder. The Trustee and such successor shall take such action, consistent with this Agreement, as shall be necessary to effectuate any such succession. Neither the Trustee nor any other Successor Master Servicer shall be deemed to be in default hereunder by reason of any failure to make, or any delay in making, any distribution hereunder or any portion thereof or any failure to perform, or any delay in performing, any duties or responsibilities hereunder, in either case caused by the failure of the Master Servicer and the Securities Administrator to deliver or provide, or any delay in delivering or providing, any cash, information, documents or records to it.

The costs and expenses of the Trustee in connection with the termination of the Master Servicer, appointment of a Successor Master Servicer and, if applicable, any transfer of servicing, including, without limitation, all costs and 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 Trustee to correct any errors or insufficiencies in the servicing data or otherwise to enable the Trustee or the Successor Master Servicer to service the related Mortgage Loans properly and effectively, to the extent not paid by the terminated Master Servicer, shall be payable to the Trustee pursuant to Section 10.05. Any successor to the Master Servicer as successor servicer under any Subservicing Agreement shall give notice to the applicable Mortgagors of such change of servicer and shall, during the term of its service as successor servicer maintain in force the policy or policies that the Master Servicer is required to maintain pursuant to Section 4.04.

Section 9.03

Notification to Certificateholders.

(a) Upon any termination of or appointment of a successor to the Master Servicer, the Trustee shall give prompt written notice thereof to Certificateholders and to each Rating Agency.

(b) Within 60 days after the occurrence of any Event of Default, the Trustee shall transmit by mail to all Certificateholders notice of each such Event of Default hereunder actually known to a Responsible Officer of the Trustee, unless such Event of Default shall have been cured or waived.

Section 9.04

Waiver of Defaults.

The Trustee shall transmit by mail to all Certificateholders, within 60 days after the occurrence of any Event of Default actually known to a Responsible Officer of the Trustee, unless such Event of Default shall have been cured, notice of each such Event of Default hereunder known to the Trustee. The Holders of Certificates evidencing not less than 51% of the Voting Rights may, on behalf of all Certificateholders, waive any default by the Master Servicer in the performance of its obligations hereunder and the consequences thereof, except a default in the making of or the causing to be made of any required distribution on the Certificates. Upon any such waiver of a past default, such default shall be deemed to cease to exist, and any Event of Default arising therefrom shall be deemed to have been timely remedied for every purpose of this Agreement. No such waiver shall extend to any subsequent or other default or impair any right consequent thereon except to the extent expressly so waived. The Trustee shall give notice of any such waiver to the Rating Agencies.

Section 9.05

Company Default.

In case one or more of the following events of default by the Company (each, a “Company Default”) shall occur and be continuing, that is to say:

(i) any failure by the Company to remit to the Master Servicer any payment required to be made under the terms of this Agreement on any Remittance Date; or

(ii)	failure on the part of the Company duly to observe or perform in any

material respect any other of the covenants or agreements (other than Sections 3.13 or 3.14) on the part of the Company set forth in this Agreement, the breach of which has a material adverse effect and which continue unremedied for a period of sixty days (except that such number of days shall be fifteen in the case of a failure to pay any premium for any insurance policy required to be maintained under this Agreement and such failure shall be deemed to have a material adverse effect) after the date on which written notice of such failure, requiring the same to be remedied, shall have been given to the Company by the Master Servicer; or

(iii) a decree or order of a court or agency or supervisory authority having jurisdiction for the appointment of a conservator or receiver or liquidator in any insolvency, bankruptcy, readjustment of debt, marshaling of assets and liabilities or similar proceedings, or for the winding-up or liquidation of its affairs, shall have been entered against the Company and such decree or order shall have remained in force undischarged or unstayed for a period of sixty days; or

(iv) the Company shall consent to the appointment of a conservator or receiver or liquidator in any insolvency, bankruptcy, readjustment of debt, marshaling of assets and liabilities or similar proceedings of or relating to the Company or of or relating to all or substantially all of its property; or

(v) the Company shall admit in writing its inability to pay its debts generally as they become due, file a petition to take advantage of any applicable insolvency or reorganization statute, make an assignment for the benefit of its creditors, or voluntarily suspend payment of its obligations; or

(vi) the Company attempts to assign its right to servicing compensation hereunder or the Company attempts to sell or otherwise dispose of all or substantially all of its property or assets or to assign this Agreement or the servicing responsibilities hereunder or to delegate its duties hereunder or any portion thereof except as otherwise permitted herein; or

(vii) the Company ceases to be qualified to transact business in any jurisdiction where it is currently so qualified, but only to the extent such non-qualification materially and adversely affects the Company’s ability to perform its obligations hereunder;

(viii) failure by the Company to duly perform, within the required time period, its obligations under Section 3.13 or Section 3.14 which failure continues unremedied for a period of fifteen (15) days after the date on which written notice of such failure, requiring the same to be remedied, shall have been given to the Company by the Master Servicer.

then, and in each and every such case, so long as a Company Default shall not have been remedied, the Master Servicer, by notice in writing to the Company may, in addition to whatever rights the Master Servicer and the Trustee on behalf of the Certificateholders may have under Section 8.03 and at law or equity to damages, including injunctive relief and specific performance, terminate all the rights and obligations of the Company under this Agreement and in and to the EMC Mortgage Loans and the proceeds thereof without compensating the Company for the same. On or after the receipt by the Company of such written notice, all authority and power of Company under this Agreement, whether with respect to the EMC Mortgage Loans or otherwise, shall pass to and be vested in the Master Servicer. Upon written request from the

Master Servicer, the Company shall prepare, execute and deliver, any and all documents and other instruments, place in the Master Servicer’s possession all Mortgage Files relating to the EMC Mortgage Loans, and 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 EMC Mortgage Loans and related documents, or otherwise, at the Company’s sole expense. The Company agrees to cooperate with the Master Servicer in effecting the termination of the Company’s responsibilities and rights hereunder, including, without limitation, the transfer to such successor for administration by it of all cash amounts which shall at the time be credited by the Company to its Protected Account or Escrow Account or thereafter received with respect to the EMC Mortgage Loans or any related REO Property.

Section 9.06

Waiver of Company Defaults.

The Master Servicer, with the consent of the Trustee, may waive only by written notice any default by the Company in the performance of its obligations hereunder and its consequences. Upon any such waiver of a past default, such default shall cease to exist, and any Company Default arising therefrom shall be deemed to have been remedied for every purpose of this Agreement. No such waiver shall extend to any subsequent or other default or impair any right consequent thereon except to the extent expressly so waived in writing.

(i) Prior to the occurrence of an Event of Default, and after the curing or waiver of all such 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 and the Securities Administrator 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 their respective 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

(ii) Neither the Trustee nor the Securities Administrator shall be liable in its individual capacity 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;

(iv) The Trustee shall not be required to take notice or be deemed to have notice or knowledge of any default or Event of Default unless a Responsible Officer of the Trustee shall have actual knowledge thereof. In the absence of such notice, the Trustee may conclusively assume there is no such default or Event of Default;

(v) The Trustee shall not in any way be liable by reason of any insufficiency in any Account held by or in the name of Trustee unless it is determined by a court of competent jurisdiction in a non-appealable judgment that the Trustee’s gross negligence or willful misconduct was the primary cause of such insufficiency (except to the extent that the Trustee is obligor and has defaulted thereon);

(vi) Anything in this Agreement to the contrary notwithstanding, in no event shall the Trustee or the Securities Administrator be liable for special, indirect or consequential loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Trustee or the Securities Administrator, respectively, has been advised of the likelihood of such loss or damage and regardless of the form of action; and

(vii) None of the Securities Administrator, the Master Servicer, the Seller, the Depositor or the Trustee shall be responsible for the acts or omissions of the other, it being understood that this Agreement shall not be construed to render them partners, joint venturers or agents of one another.

Neither the Trustee nor the Securities Administrator shall be required to expend or risk its own funds or otherwise incur financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if there is reasonable ground for believing that the repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it, and none of the provisions contained in this Agreement shall in any event require the Trustee or the Securities Administrator to perform, or be responsible for the manner of performance of, any of the obligations of the Master Servicer or the Company hereunder or any Servicer under the related Servicing Agreement.

(e) All funds received by the Securities Administrator and required to be deposited in the Distribution Account pursuant to this Agreement will be promptly so deposited by the Securities Administrator.

(i) The Trustee and the Securities Administrator may rely and shall be protected in acting or refraining from acting in reliance on any resolution or certificate of the Seller, the Company, the Master Servicer or the related Servicer, any certificates of auditors or any other certificate, statement, instrument, opinion, report, notice, request, consent, order, appraisal, bond or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties;

(ii) The Trustee and the Securities Administrator may consult with counsel and any advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection with respect to any action taken or suffered or omitted by it hereunder in good faith and in accordance with such advice or Opinion of Counsel;

(iii) Neither the Trustee nor the Securities Administrator shall be under any obligation to exercise any of the trusts or powers vested in it by this Agreement, other than its obligation to give notices pursuant to this Agreement, or to institute, conduct or defend any litigation hereunder or in relation hereto at the request, order or direction of any of the Certificateholders pursuant to the provisions of this Agreement, unless such Certificateholders shall have offered to the Trustee or the Securities Administrator, as applicable, reasonable security or indemnity against the costs, expenses and liabilities which may be incurred therein or thereby. Nothing contained herein shall, however, relieve the Trustee of the obligation, upon the occurrence of an Event of Default of which a Responsible Officer of the Trustee has actual knowledge (which has not been cured or waived), to exercise such of the rights and powers vested in it by this Agreement, and to use the same degree of care and skill in their exercise, as a prudent person would exercise under the circumstances in the conduct of his own affairs;

(iv) Prior to the occurrence of an Event of Default hereunder and after the curing or waiver of all Events of Default which may have occurred with respect to the Trustee and at all times with respect to the Securities Administrator, neither the Trustee nor the Securities Administrator shall be liable in its individual capacity for any action taken, suffered or omitted by it in good faith and believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Agreement;

(v) Neither the Trustee nor the Securities Administrator shall be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, approval, bond or other paper or document, unless requested in writing to do so by Holders of Certificates evidencing not less than 25% of the aggregate Voting Rights of the Certificates and provided that the payment within a reasonable time to the Trustee or the Securities Administrator, as applicable, of the costs, expenses or liabilities likely to be incurred by it

in the making of such investigation is, in the opinion of the Trustee or the Securities Administrator, as applicable, reasonably assured to the Trustee or the Securities Administrator, as applicable, by the security afforded to it by the terms of this Agreement. The Trustee or the Securities Administrator may require reasonable indemnity against such expense or liability as a condition to taking any such action. The reasonable expense of every such examination shall be paid by the Certificateholders requesting the investigation;

(vi) The Trustee and the Securities Administrator may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or through Affiliates, agents or attorneys; provided, however, that the Trustee may not appoint any paying agent other than the Securities Administrator to perform any paying agent functions under this Agreement without the express written consent of the Master Servicer, which consent will not be unreasonably withheld. Neither the Trustee nor the Securities Administrator shall be liable or responsible for the misconduct or negligence of any of the Trustee’s or the Securities Administrator’s agents or attorneys or paying agent appointed hereunder by the Trustee or the Securities Administrator with due care and, when required, with the consent of the Master Servicer;

(vii) Should the Trustee or the Securities Administrator deem the nature of any action required on its part to be unclear, the Trustee or the Securities Administrator, respectively, may require prior to such action that it be provided by the Depositor with reasonable further instructions; the right of the Trustee or the Securities Administrator to perform any discretionary act enumerated in this Agreement shall not be construed as a duty, and neither the Trustee nor the Securities Administrator shall be accountable for other than its negligence or willful misconduct in the performance of any such act;

(viii) Neither the Trustee nor the Securities Administrator shall be required to give any bond or surety with respect to the execution of the trust created hereby or the powers granted hereunder, except as provided in Subsection 10.07; and

(ix) Neither the Trustee nor the Securities Administrator shall have any duty to conduct any affirmative investigation as to the occurrence of any condition requiring the repurchase of any Mortgage Loan by any Person pursuant to this Agreement, or the eligibility of any Mortgage Loan for purposes of this Agreement.

Section 10.03 Trustee and Securities Administrator Not Liable for Certificates or Mortgage Loans.

The recitals contained herein and in the Certificates (other than the signature and countersignature of the Trustee on the Certificates) shall be taken as the statements of the Depositor, and neither the Trustee nor the Securities Administrator shall have any responsibility for their correctness. Neither the Trustee nor the Securities Administrator makes any representation as to the validity or sufficiency of the Certificates (other than the signature and countersignature of the Trustee on the Certificates) or of any Mortgage Loan except as expressly provided in Sections 2.02 and 2.06 hereof; provided, however, that the foregoing shall not relieve the Trustee, or the Custodian on its behalf, of the obligation to review the Mortgage Files pursuant to Section 2.02 of this Agreement. The Trustee’s signature and countersignature (or

countersignature of its agent) on the Certificates shall be solely in its capacity as Trustee and shall not constitute the Certificates an obligation of the Trustee in any other capacity. Neither the Trustee or the Securities Administrator shall be accountable for the use or application by the Depositor of any of the Certificates or of the proceeds of such Certificates, or for the use or application of any funds paid to the Depositor with respect to the Mortgage Loans. Subject to Section 2.06, neither the Trustee nor the Securities Administrator shall be responsible for the legality or validity of this Agreement or any document or instrument relating to this Agreement, the validity of the execution of this Agreement or of any supplement hereto or instrument of further assurance, or the validity, priority, perfection or sufficiency of the security for the Certificates issued hereunder or intended to be issued hereunder. Neither the Trustee nor the Securities Administrator shall at any time have any responsibility or liability for or with respect to the legality, validity and enforceability of any Mortgage or any Mortgage Loan, or the perfection and priority of any Mortgage or the maintenance of any such perfection and priority, or for or with respect to the sufficiency of the Trust Fund or its ability to generate the payments to be distributed to Certificateholders, under this Agreement. Neither the Trustee nor the Securities Administrator shall have any responsibility for filing any financing or continuation statement in any public office at any time or to otherwise perfect or maintain the perfection of any security interest or lien granted to it hereunder or to record this Agreement.

Section 10.04

Trustee and Securities Administrator May Own Certificates.

Each of the Trustee and the Securities Administrator in its individual capacity or in any capacity other than as Trustee or Securities Administrator hereunder may become the owner or pledgee of any Certificates with the same rights it would have if it were not the Trustee or the Securities Administrator, as applicable, and may otherwise deal with the parties hereto.

Section 10.05

Trustee’s and Securities Administrator’s Fees and Expenses.

The fees and expenses of the Trustee and the Securities Administrator shall be paid in accordance with a side letter agreement with the Master Servicer and at the expense of the Master Servicer. In addition, the Trustee and the Securities Administrator will be entitled to recover from the Master Servicer Collection Account pursuant to Section 5.07 all reasonable out-of-pocket expenses, disbursements and advances and the expenses of the Trustee and the Securities Administrator, respectively, in connection with any Event of Default, any breach of this Agreement or any claim or legal action (including any pending or threatened claim or legal action) incurred or made by the Trustee or the Securities Administrator, respectively, in the administration of the trusts hereunder (including the reasonable compensation, expenses and disbursements of its counsel) except any such expense, disbursement or advance as may arise from its negligence or intentional misconduct or which is the responsibility of the Certificateholders or the Trust Fund hereunder. If funds in the Master Servicer Collection Account are insufficient therefor, the Trustee and the Securities Administrator shall recover such expenses, disbursements or advances from the Depositor and the Depositor hereby agrees to pay such expenses, disbursements or advances upon demand. Such compensation and reimbursement obligation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust.

Section 10.06

Eligibility Requirements for Trustee and Securities Administrator.

The Trustee and any successor Trustee and the Securities Administrator and any successor Securities Administrator shall during the entire duration of this Agreement be a state bank or trust company or a national banking association organized and doing business under the laws of a state or the United States of America, authorized under such laws to exercise corporate trust powers, having a combined capital and surplus and undivided profits of at least $40,000,000 or, in the case of a successor Trustee, $50,000,000, subject to supervision or examination by federal or state authority and, in the case of the Trustee, rated “BBB” or higher by Fitch, Inc. Ratings with respect to their long-term rating and rated “BBB” or higher by Standard & Poor’s and “Baa2” or higher by Moody’s with respect to any outstanding long-term unsecured unsubordinated debt, and, in the case of a successor Trustee or successor Securities Administrator other than pursuant to Section 10.10, rated in one of the two highest long-term debt categories of, or otherwise acceptable to, each of the Rating Agencies. The Trustee shall not be an Affiliate of the Master Servicer. If the Trustee publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section 10.06 the combined capital and surplus of such corporation shall be deemed to be its total equity capital (combined capital and surplus) as set forth in its most recent report of condition so published. In case at any time the Trustee or the Securities Administrator, as applicable, shall cease to be eligible in accordance with the provisions of this Section 10.06, the Trustee or the Securities Administrator shall resign immediately in the manner and with the effect specified in Section 10.08.

Section 10.07

The Trustee and the Securities Administrator, at their own expense, shall at all times maintain and keep in full force and effect: (i) fidelity insurance, (ii) theft of documents insurance and (iii) forgery insurance (which may be collectively satisfied by a “Financial Institution Bond” and/or a “Bankers’ Blanket Bond”). All such insurance shall be in amounts, with standard coverage and subject to deductibles, as are customary for insurance typically maintained by banks or their affiliates which act as custodians for investor-owned mortgage pools. A certificate of an officer of the Trustee or the Securities Administrator as to the Trustee’s or the Securities Administrator’s, respectively, compliance with this Section 10.07 shall be furnished to any Certificateholder upon reasonable written request.

Section 10.08

Resignation and Removal of Trustee and Securities Administrator.

The Trustee and the Securities Administrator may at any time resign (including, in the case of the Securities Administrator, in connection with the resignation or termination of the Master Servicer) and be discharged from the Trust hereby created by giving written notice thereof to the Depositor, the Seller, the Securities Administrator (or the Trustee, if the Securities Administrator resigns) and the Master Servicer, with a copy to the Rating Agencies. Upon receiving such notice of resignation, the Depositor shall promptly appoint a successor trustee or successor securities administrator, as applicable, by written instrument, in triplicate, one copy of which instrument shall be delivered to each of the resigning trustee or securities administrator, as applicable, and the successor trustee or securities administrator, as applicable. If no successor trustee or successor securities administrator shall have been so appointed and have accepted appointment within 30 days after the giving of such notice of resignation, the resigning Trustee

or Securities Administrator may petition any court of competent jurisdiction for the appointment of a successor trustee or securities administrator.

If at any time (i) the Trustee or the Securities Administrator shall cease to be eligible in accordance with the provisions of Section 10.06 hereof and shall fail to resign after written request thereto by the Depositor, (ii) the Trustee or the Securities Administrator shall become incapable of acting, or shall be adjudged as bankrupt or insolvent, or a receiver of the Trustee or the Securities Administrator or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or the Securities Administrator or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, or (iii)(A) a tax is imposed with respect to the Trust Fund by any state in which the Trustee or the Securities Administrator or the Trust Fund is located, (B) the imposition of such tax would be avoided by the appointment of a different trustee or securities administrator and (C) the Trustee or the Securities Administrator, as applicable fails to indemnify the Trust Fund against such tax, then the Depositor or the Master Servicer may remove the Trustee or the Securities Administrator, as applicable, and appoint a successor trustee or successor securities administrator, as applicable, by written instrument, in multiple copies, a copy of which instrument shall be delivered to the Trustee, the Securities Administrator, each Master Servicer and the successor trustee or successor securities administrator, as applicable.

The Holders evidencing at least 51% of the Voting Rights of each Class of Certificates may at any time remove the Trustee or Securities Administrator and appoint a successor trustee or securities administrator by written instrument or instruments, in multiple copies, signed by such Holders or their attorneys-in-fact duly authorized, one complete set of which instruments shall be delivered by the successor trustee or successor securities administrator to each of the Master Servicer, the Trustee or Securities Administrator so removed and the successor trustee or securities administrator so appointed. Notice of any removal of the Trustee or Securities Administrator shall be given to each Rating Agency by the Trustee or successor trustee.

Any resignation or removal of the Trustee or Securities Administrator and appointment of a successor trustee or securities administrator pursuant to any of the provisions of this Section 10.08 shall become effective upon acceptance of appointment by the successor trustee or securities administrator as provided in Section 10.09 hereof.

Section 10.09

Successor Trustee or Securities Administrator.

Any successor trustee or securities administrator appointed as provided in Section 10.08 hereof shall execute, acknowledge and deliver to the Depositor and to its predecessor trustee or predecessor securities administrator, as applicable, and the Master Servicer an instrument accepting such appointment hereunder and thereupon the resignation or removal of the predecessor trustee or securities administrator shall become effective and such successor trustee or securities administrator, without any further act, deed or conveyance, shall become fully vested with all the rights, powers, duties and obligations of its predecessor hereunder, with the like effect as if originally named as trustee or securities administrator herein.

No successor trustee or securities administrator shall accept appointment as provided in this Section 10.09 unless at the time of such acceptance such successor trustee or securities

administrator shall be eligible under the provisions of Section 10.07 hereof and its appointment shall not adversely affect the then current rating of the Certificates.

Upon acceptance of appointment by a successor trustee or securities administrator as provided in this Section 10.09, the successor trustee or securities administrator shall mail notice of the succession of such trustee or securities administrator hereunder to all Holders of Certificates. If the successor trustee or securities administrator fails to mail such notice within ten days after acceptance of appointment, the Depositor shall cause such notice to be mailed at the expense of the Trust Fund.

Section 10.10

Merger or Consolidation of Trustee or Securities Administrator.

Any corporation, state bank or national banking association into which the Trustee or the Securities Administrator may be merged or converted or with which it may be consolidated or any corporation, state bank or national banking association resulting from any merger, conversion or consolidation to which the Trustee or the Securities Administrator shall be a party, or any corporation, state bank or national banking association succeeding to substantially all of the corporate trust business of the Trustee or of the business of the Securities Administrator, shall be the successor of the Trustee or the Securities Administrator hereunder, provided that such corporation shall be eligible under the provisions of Section 10.06 hereof without the execution or filing of any paper or further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding.

Section 10.11

Appointment of Co-Trustee or Separate Trustee.

Notwithstanding any other provisions of this Agreement, at any time, for the purpose of meeting any legal requirements of any jurisdiction in which any part of the Trust Fund or property securing any Mortgage Note may at the time be located, the Master Servicer and the Trustee acting jointly shall have the power and shall execute and deliver all instruments to appoint one or more Persons approved by the Trustee to act as co-trustee or co-trustees jointly with the Trustee, or separate trustee or separate trustees, of all or any part of the Trust Fund, and to vest in such Person or Persons, in such capacity and for the benefit of the Certificateholders, such title to the Trust Fund or any part thereof, whichever is applicable, and, subject to the other provisions of this Section 10.11, such powers, duties, obligations, rights and trusts as the Master Servicer and the Trustee may consider necessary or desirable. If the Master Servicer shall not have joined in such appointment within 15 days after the receipt by it of a request to do so, or in the case an Event of Default shall have occurred and be continuing, the Trustee alone shall have the power to make such appointment. No co-trustee or separate trustee hereunder shall be required to meet the terms of eligibility as a successor trustee under Section 10.06 and no notice to Certificateholders of the appointment of any co-trustee or separate trustee shall be required under Section 10.09.

Every separate trustee and co-trustee shall, to the extent permitted by law, be appointed and act subject to the following provisions and conditions:

(i) All rights, powers, duties and obligations conferred or imposed upon the Trustee, except for the obligation of the Trustee under this Agreement to advance funds on behalf of the Master Servicer, shall be conferred or imposed upon and exercised or

performed by the Trustee and such separate trustee or co-trustee jointly (it being understood that such separate trustee or co-trustee is not authorized to act separately without the Trustee joining in such act), except to the extent that under any law of any jurisdiction in which any particular act or acts are to be performed (whether a Trustee hereunder or as a Successor Master Servicer hereunder), the Trustee shall be incompetent or unqualified to perform such act or acts, in which event such rights, powers, duties and obligations (including the holding of title to the Trust Fund or any portion thereof in any such jurisdiction) shall be exercised and performed singly by such separate trustee or co-trustee, but solely at the direction of the Trustee;

(ii) No trustee hereunder shall be held personally liable by reason of any act or omission of any other trustee hereunder; and

(iii) The Trustee may at any time accept the resignation of or remove any separate trustee or co-trustee.

Any notice, request or other writing given to the Trustee shall be deemed to have been given to each of the then separate trustees and co-trustees, as effectively as if given to each of them. Every instrument appointing any separate trustee or co-trustee shall refer to this Agreement and the conditions of this Article X. Each separate trustee and co-trustee, upon its acceptance of the trusts conferred, shall be vested with the estates or property specified in its instrument of appointment, either jointly with the Trustee or separately, as may be provided therein, subject to all the provisions of this Agreement, specifically including every provision of this Agreement relating to the conduct of, affecting the liability of, or affording protection to, the Trustee. Every such instrument shall be filed with the Trustee and a copy thereof given to the Master Servicer and the Depositor.

Any separate trustee or co-trustee may, at any time, constitute the Trustee its agent or attorney-in-fact, with full power and authority, to the extent not prohibited by law, to do any lawful act under or in respect of this Agreement on its behalf and in its name. If any separate trustee or co- trustee shall die, become incapable of acting, resign or be removed, all of its estates, properties, rights, remedies and trusts shall vest in and be exercised by the Trustee, to the extent permitted by law, without the appointment of a new or successor trustee.

Section 10.12

Tax Matters.

It is intended that the Trust Fund shall constitute, and that the affairs of the Trust Fund shall be conducted so that each REMIC formed hereunder qualifies as, a “real estate mortgage investment conduit” as defined in and in accordance with the REMIC Provisions. In furtherance of such intention, the Securities Administrator covenants and agrees that it shall act as agent for so long as it is also Master Servicer (and the Securities Administrator is hereby appointed to act as agent) on behalf of the Trust Fund. The Trustee and/or the Securities Administrator, as agent on behalf of the Trust Fund, shall do or refrain from doing, as applicable, the following: (a) the Securities Administrator shall prepare and file, or cause to be prepared and filed, in a timely manner, U.S. Real Estate Mortgage Investment Conduit Income Tax Returns (Form 1066 or any successor form adopted by the Internal Revenue Service) and prepare and file or cause to be prepared and filed with the Internal Revenue Service and applicable state or local tax authorities income tax or information returns for each taxable year with respect to each such REMIC

containing such information and at the times and in the manner as may be required by the Code or state or local tax laws, regulations, or rules, and furnish or cause to be furnished to Certificateholders the schedules, statements or information at such times and in such manner as may be required thereby; (b) 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 that is or becomes a taxable entity, and within thirty days of the Closing Date, furnish or cause to be furnished to the Internal Revenue Service, on Form 8811 or as otherwise may be required by the Code, the name, title, address, and telephone number of the person that the Holders of the Certificates may contact for tax information relating thereto, together with such additional information as may be required by such form, and update such information at the time or times in the manner required by the Code for the Trust Fund; (c) the Trustee shall make or cause to be made elections, on behalf of each REMIC formed hereunder to be treated as a REMIC on the federal tax return of such REMIC for its first taxable year (and, if necessary, under applicable state law); (d) the Securities Administrator shall prepare and forward, or cause to be prepared and forwarded, to the Certificateholders and to the Internal Revenue Service and, if necessary, state tax authorities, all information returns and reports as and when required to be provided to them in accordance with the REMIC Provisions, including without limitation, the calculation of any original issue discount using the Prepayment Assumption; (e) the Securities Administrator shall provide information necessary for the computation of tax imposed on the transfer of a Residual Certificate to a Person that is not a Permitted Transferee, or an agent (including a broker, nominee or other middleman) of a Person that is not a Permitted Transferee, or a pass-through entity in which a Person that is not a Permitted Transferee is the record holder of an interest (the reasonable cost of computing and furnishing such information may be charged to the Person liable for such tax); (f) each of the Securities Administrator and the Trustee shall, to the extent under its control, conduct the affairs of the Trust Fund at all times that any Certificates are outstanding so as to maintain the status of each REMIC formed hereunder as a REMIC under the REMIC Provisions; (g) neither the Trustee nor the Securities Administrator shall knowingly or intentionally take any action or omit to take any action that would cause the termination of the REMIC status of any REMIC formed hereunder; (h) the Trustee shall pay, from the sources specified in the penultimate paragraph of this Section 10.12, as directed by the Securities Administrator in its Remittance Report, the amount of any federal, state and local taxes, including prohibited transaction taxes as described below, imposed on any REMIC formed hereunder prior to the termination of the Trust Fund when and as the same shall be due and payable (but such obligation shall not prevent the Trustee, the Securities Administrator at the written request of the Trustee, or any other appropriate Person from contesting any such tax in appropriate proceedings and shall not prevent the Securities Administrator from withholding payment of such tax, if permitted by law, pending the outcome of such proceedings); (i) the Trustee shall sign or cause to be signed federal, state or local income tax or information returns or any other document prepared by the Securities Administrator pursuant to this Section 10.12 requiring a signature thereon by the Trustee; (j) the Securities Administrator shall maintain records relating to each REMIC formed hereunder including but not limited to the income, expenses, assets and liabilities of each such REMIC and adjusted basis of the Trust Fund property determined at such intervals as may be required by the Code, as may be necessary to prepare the foregoing returns, schedules, statements or information; (k) the Securities Administrator shall, for federal income tax purposes, maintain books and records with respect to the REMICs on a calendar year and on an accrual basis; (l) neither the Trustee nor the Master Servicer shall enter into any arrangement not otherwise

provided for in this Agreement by which the REMICs will receive a fee or other compensation for services nor permit the REMICs 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; and (m) as and when necessary and appropriate, the Trustee, or at the written request of the Trustee, the Securities Administrator, shall represent the Trust Fund in any administrative or judicial proceedings relating to an examination or audit by any governmental taxing authority, request an administrative adjustment as to any taxable year of any REMIC formed hereunder, enter into settlement agreements with any governmental taxing agency, extend any statute of limitations relating to any tax item of the Trust Fund, and otherwise act on behalf of each REMIC formed hereunder in relation to any tax matter involving any such REMIC.

In order to enable each of the Trustee and the Securities Administrator to perform its duties as set forth herein, the Depositor shall provide, or cause to be provided, to the Trustee or the Securities Administrator within 10 days after the Closing Date all information or data that the Trustee or the Securities Administrator requests in writing and determines to be relevant for tax purposes to the valuations and offering prices of the Certificates, including, without limitation, the price, yield, Prepayment Assumption and projected cash flows of the Certificates and the Mortgage Loans. Thereafter, the Depositor shall provide to the Trustee or the Securities Administrator promptly upon written request therefor, any such additional information or data that the Trustee or the Securities Administrator may, from time to time, request in order to enable the Trustee or the Securities Administrator to perform its duties as set forth herein. The Depositor hereby indemnifies each of Trustee and the Securities Administrator for any losses, liabilities, damages, claims or expenses of the Trustee or the Securities Administrator arising from any errors or miscalculations of the Trustee or the Securities Administrator, as applicable, that result from any failure of the Depositor to provide, or to cause to be provided, accurate information or data to the Trustee or the Securities Administrator, as applicable, on a timely basis.

In the event that any tax is imposed on “prohibited transactions” of any of REMIC I or REMIC II as defined in Section 860F(a)(2) of the Code, on the “net income from foreclosure property” of the Trust Fund as defined in Section 860G(c) of the Code, on any contribution to any of REMIC I or REMIC II after the Startup Day pursuant to Section 860G(d) of the Code, or any other tax is imposed, including, without limitation, any federal, state or local tax or minimum tax imposed upon any of REMIC I or REMIC II, and is not paid as otherwise provided for herein, such tax shall be paid by (i) the Trustee or the Securities Administrator, if any such other tax arises out of or results from a breach by the Trustee or the Securities Administrator, respectively, of any of its obligations under this Agreement, (ii) any party hereto (other than the Trustee or the Securities Administrator) to the extent any such other tax arises out of or results from a breach by such other party of any of its obligations under this Agreement or (iii) in all other cases, or in the event that any liable party hereto fails to honor its obligations under the preceding clauses (i) or (ii), any such tax will be paid first with amounts otherwise to be distributed to the Class R Certificateholders, and second with amounts otherwise to be distributed to the following other Certificates in the following order of priority: first, to the Class B-4 Certificates, second, to the Class B-3 Certificates, third, to the Class B-2 Certificates, fourth, to the Class B-1 Certificates, fifth, to the Class M-3 Certificates, sixth, to the Class M-2

Certificates, seventh, to the Class M-1 Certificates, and eighth, to the Class A Certificates, based on the amounts to be distributed.

Notwithstanding anything to the contrary contained herein, to the extent that such tax is payable by the Holder of any Certificates, the Securities Administrator is hereby authorized to retain on any Distribution Date, from the Holders of the Class R Certificates (and, if necessary, second, from the Holders of the other Certificates in the priority specified in the preceding sentence), funds otherwise distributable to such Holders in an amount sufficient to pay such tax. The Securities Administrator shall include in its Remittance Report instructions as to distributions to such parties taking into account the priorities described in the second preceding sentence. The Securities Administrator, on written request by the Trustee, agrees to promptly notify in writing the party liable for any such tax of the amount thereof and the due date for the payment thereof.

The Trustee and the Securities Administrator each agree that, in the event it should obtain any information necessary for the other party to perform its obligations pursuant to this Section 10.12, it will promptly notify and provide such information to such other party. Notwithstanding anything in this Agreement to the contrary, the Trustee agrees that, in the event that the Trustee obtains actual knowledge that the Securities Administrator has breached any of its obligations pursuant to this Section 10.12, the Trustee shall perform such obligations on its behalf to the extent that the Trustee possesses all documents necessary to so perform and receives reasonable compensation therefor, provided, however, that the Trustee shall not be liable for any losses resulting from any such breach.

Any such notice shall specify (a) the Distribution Date upon which final distribution on the Certificates will be made upon presentation and surrender of Certificates at the office therein designated, (b) the amount of such final distribution, (c) the location of the office or agency at which such presentation and surrender must be made and (d) that the Record Date otherwise applicable to such Distribution Date is not applicable, distributions being made only upon presentation and surrender of the Certificates at the office therein specified. The Securities Administrator will give such notice to each Rating Agency at the time such notice is given to Certificateholders.

In the event such notice is given, the Master Servicer shall cause all funds in the Master Servicer Collection Account to be remitted to the Securities Administrator for deposit in the Distribution Account on the Business Day prior to the applicable Distribution Date in an amount equal to the final distribution in respect of the Certificates. Upon such final deposit with respect to the Trust Fund and the receipt by the Trustee of a Request for Release therefor, the Trustee or the Custodian shall promptly release to the Master Servicer, as applicable the Mortgage Files for the Mortgage Loans and the Trustee shall execute and deliver any documents prepared and delivered to it which are necessary to transfer any REO Property.

Upon presentation and surrender of the Certificates, the Securities Administrator shall cause to be distributed to Certificateholders of each Class in accordance with the Remittance Report the amounts allocable to such Certificates held in the Distribution Account in the order and priority set forth in Section 6.04 hereof on the final Distribution Date and in proportion to their respective Percentage Interests.

In the event that any affected Certificateholders shall not surrender Certificates for cancellation within six months after the date specified in the above mentioned written notice, the Securities Administrator shall give a second written notice to the remaining Certificateholders to surrender their Certificates for cancellation and receive the final distribution with respect thereto. If within six months after the second notice all the applicable Certificates shall not have been surrendered for cancellation, the Securities Administrator may take appropriate steps, or may appoint an agent to take appropriate steps, to contact the remaining Certificateholders concerning surrender of their Certificates, and the cost thereof shall be paid out of the funds and other assets that remain a part of the Trust Fund. If within one year after the second notice all Certificates shall not have been surrendered for cancellation, the Class R Certificateholders shall be entitled to all unclaimed funds and other assets of the Trust Fund that remain subject hereto.

Section 11.03

Additional Termination Requirements.

(a) Upon exercise by the Majority Class C Certificateholder of its purchase option as provided in Section 11.01, the Trust Fund shall be terminated in accordance with the following additional requirements, unless each of the Trustee and the Securities Administrator have been supplied with an Opinion of Counsel addressed to the Trustee, at the expense of the Majority Class C Certificateholder, to the effect that the failure of the Trust Fund to comply with the requirements of this Section 11.03 will not (i) result in the imposition of taxes on “prohibited transactions” of a REMIC, or (ii) cause a REMIC to fail to qualify as a REMIC at any time that any Certificates are outstanding:

(1) The Majority Class C Certificateholder shall establish a 90-day liquidation period and notify the Trustee and Securities Administrator thereof, and the Securities Administrator shall in turn specify the first day of such period in a statement attached to the tax return for each of REMIC I and REMIC II pursuant to Treasury Regulation Section 1.860F-1. The Majority Class C Certificateholder shall satisfy all the requirements of a qualified liquidation under Section 860F of the Code and any regulations thereunder, as evidenced by an Opinion of Counsel addressed to the Trustee obtained at the expense of the Majority Class C Certificateholder;

(2) During such 90-day liquidation period, and at or prior to the time of making the final payment on the Certificates, the Securities Administrator, as agent of the Trustee, shall sell all of the assets of REMIC I for cash;

(3) At the time of the making of the final payment on the Certificates, the Securities Administrator, as agent for the Trustee, shall distribute or credit, or cause to be distributed or credited, to the Holders of the Residual Certificates all cash on hand (other than cash retained to meet claims), and REMIC I shall terminate at that time;

(4) By their acceptance of the Certificates, the Holders thereof hereby authorize the adoption of a 90-day liquidation period for REMIC I and REMIC II, which authorization shall be binding upon all successor Certificateholders; and

(5) The Securities Administrator, as agent for each REMIC, hereby agrees to adopt and sign such a plan of complete liquidation upon the written request of the Majority Class C Certificateholder, and the receipt of the Opinion of Counsel referred to in Section 11.03(a)(1), and to take such other action in connection therewith as may be reasonably requested by the Majority Class C Certificateholder.

ARTICLE XII

MISCELLANEOUS PROVISIONS

Section 12.01

Amendment.

This Agreement may be amended from time to time by parties hereto, without the consent of any of the Certificateholders to cure any ambiguity, to correct or supplement any provisions herein (including to give effect to the expectations of investors), to change the manner in which the Master Servicer Collection Account maintained by the Master Servicer or the Protected Account maintained by the Company is maintained or to make such other provisions with respect to matters or questions arising under this Agreement as shall not be inconsistent with any other provisions herein if such action shall not, as evidenced by an Opinion of Counsel addressed to the Trustee, adversely affect in any material respect the interests of any Certificateholder; provided that any such amendment shall be deemed not to adversely affect in any material respect the interests of the Certificateholders and no such Opinion of Counsel shall be required if the Person requesting such amendment obtains a letter from each Rating Agency stating that such amendment would not result in the downgrading or withdrawal of the respective ratings then assigned to the Certificates.

Notwithstanding the foregoing, without the consent of the Certificateholders, the parties hereto may at any time and from time to time amend this Agreement to modify, eliminate or add to any of its provisions to such extent as shall be necessary or appropriate to maintain the qualification of each of REMIC I and REMIC II as a REMIC under the Code or to avoid or minimize the risk of the imposition of any tax on any of REMIC I or REMIC II pursuant to the Code that would be a claim against any of REMIC I or REMIC II at any time prior to the final redemption of the Certificates, provided that the Trustee has been provided an Opinion of Counsel addressed to the Trustee, which opinion shall be an expense of the party requesting such opinion but in any case shall not be an expense of the Trustee, the Securities Administrator or the Trust Fund, to the effect that such action is necessary or appropriate to maintain such qualification or to avoid or minimize the risk of the imposition of such a tax.

This Agreement may also be amended from time to time by the parties hereto and the Holders of each Class of Certificates affected thereby evidencing over 50% of the Voting Rights of such Class or Classes for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Agreement or of modifying in any manner the rights of the Holders of Certificates; provided that no such amendment shall (i) reduce in any manner the amount of, or delay the timing of, payments required to be distributed on any Certificate without the consent of the Holder of such Certificate, (ii) cause any of REMIC I or REMIC II to cease to qualify as a REMIC or (iii) reduce the aforesaid percentages of Certificates of each Class the Holders of which are required to consent to any such amendment without the consent of the Holders of all Certificates of such Class then outstanding.

Notwithstanding any contrary provision of this Agreement, the Trustee shall not consent to any amendment to this Agreement unless it shall have first received an Opinion of Counsel addressed to the Trustee , which opinion shall be an expense of the party requesting such amendment but in any case shall not be an expense of the Trustee or the Securities Administrator, to the effect that such amendment will not (other than an amendment pursuant to

clause (ii) of, and in accordance with, the preceding paragraph) cause the imposition of any tax on REMIC I, REMIC II or the Certificateholders or cause REMIC I or REMIC II to cease to qualify as a REMIC at any time that any Certificates are outstanding. Further, nothing in this Agreement shall require the Trustee to enter into an amendment without receiving an Opinion of Counsel, satisfactory to the Trustee (i) that such amendment is permitted and is not prohibited by this Agreement and (ii) that all requirements for amending this Agreement (including any consent of the applicable Certificateholders) have been complied with.

Promptly after the execution of any amendment to this Agreement requiring the consent of Certificateholders, the Trustee shall furnish written notification of the substance of such amendment to each Certificateholder and each Rating Agency.

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

Section 12.02

Recordation of Agreement; Counterparts.

To the extent permitted by applicable law, this Agreement is subject to recordation in all appropriate public offices for real property records in all of the counties or other comparable jurisdictions in which any or all of the Mortgaged Properties are situated, and in any other appropriate public recording office or elsewhere. The Master Servicer shall effect such recordation at the Trust’s expense upon the request in writing of a Certificateholder, but only if such direction is accompanied by an Opinion of Counsel (provided at the expense of the Certificateholder requesting recordation) to the effect that such recordation would materially and beneficially affect the interests of the Certificateholders or is required by law.

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

Section 12.03

Governing Law.

THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE SUBSTANTIVE LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED IN THE STATE OF NEW YORK AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HERETO AND THE CERTIFICATEHOLDERS SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS WITHOUT REGARD TO THE CONFLICTS OF LAWS PRINCIPLES THEREOF (OTHER THAN SECTION 5-1401 OF THE GENERAL OBLIGATIONS LAWS).

Section 12.04

Intention of Parties.

It is the express intent of the parties hereto that the conveyance of the Mortgage Notes, Mortgages, assignments of Mortgages, title insurance policies and any modifications, extensions and/or assumption agreements and private mortgage insurance policies relating to the Mortgage Loans by the Seller to the Depositor, and by the Depositor to the Trustee be, and be construed as, an absolute sale thereof to the Depositor or the Trustee, as applicable. It is, further, not the intention of the parties that such conveyance be deemed a pledge thereof by the Seller to the Depositor, or by the Depositor to the Trustee. However, in the event that, notwithstanding the intent of the parties, such assets are held to be the property of the Seller or the Depositor, as applicable, or if for any other reason the Mortgage Loan Purchase Agreement or this Agreement is held or deemed to create a security interest in such assets, then (i) the Mortgage Loan Purchase Agreement and this Agreement shall each be deemed to be a security agreement within the meaning of the Uniform Commercial Code of the State of New York and (ii) the conveyance provided for in the Mortgage Loan Purchase Agreement from the Seller to the Depositor, and the conveyance provided for in this Agreement from the Depositor to the Trustee, shall be deemed to be an assignment and a grant by the Seller or the Depositor, as applicable, for the benefit of the Certificateholders, of a security interest in all of the assets that constitute the Trust Fund, whether now owned or hereafter acquired.

The Depositor for the benefit of the Certificateholders shall, to the extent consistent with this Agreement, take such actions as may be necessary to ensure that, if this Agreement were deemed to create a security interest in the assets of the Trust Fund, such security interest would be deemed to be a perfected security interest of first priority under applicable law and will be maintained as such throughout the term of the Agreement.

Section 12.05

(ii)	The occurrence of any Event of Default that has not been cured;

(iii) The resignation or termination of the Master Servicer, the Securities Administrator or the Trustee and the appointment of any successor;

case of the Depositor, Bear Stearns Asset Backed Securities I LLC, 383 Madison Avenue, New York, New York 10179, Attention: Chief Counsel; (ii) in the case of the Seller or the Company, EMC Mortgage Corporation, 909 Hidden Ridge Drive, Irving, Texas 75038, Attention: Ralene Ruyle or such other address as may be hereafter furnished to the other parties hereto by the Master Servicer in writing; (iv) in the case of the Trustee, at each Corporate Trust Office or such other address as the Trustee may hereafter furnish to the other parties hereto; (v) in the case of the Master Servicer or the Securities Administrator, P.

Any notice required or permitted to be mailed to a Certificateholder, unless otherwise provided herein, shall be given by first-class mail, postage prepaid, at the address of such Certificateholder as shown in the Certificate Register; any notice so mailed within the time prescribed in this Agreement shall be conclusively presumed to have been duly given, whether or not the Certificateholder receives such notice.

Section 12.06

Severability of Provisions.

If any one or more of the covenants, agreements, provisions or terms of this Agreement shall be for any reason whatsoever held invalid, then such covenants, agreements, provisions or terms shall be deemed severable from the remaining covenants, agreements, provisions or terms of this Agreement and shall in no way affect the validity or enforceability of the other provisions of this Agreement or of the Certificates or the rights of the Holders thereof.

Section 12.07

Assignment.

Notwithstanding anything to the contrary contained herein, except as provided pursuant to Section 8.02, this Agreement may not be assigned by the Master Servicer, the Seller or the Depositor.

Section 12.08

Limitation on Rights of Certificateholders.

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

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

No Certificateholder shall have any right by virtue or by availing itself of any provisions of this Agreement to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Agreement, unless such Holder previously shall have given to the Trustee or the Securities Administrator, as appropriate, a written notice of an Event of Default and of the continuance thereof, as hereinbefore provided, the Holders of Certificates evidencing not less than 25% of the Voting Rights evidenced by the Certificates shall also have made written request to the Trustee or the Securities Administrator, as appropriate to institute such action, suit or proceeding in its own name as Trustee or the Securities Administrator, as appropriate, hereunder and shall have offered to the Trustee or the Securities Administrator, as appropriate, such reasonable indemnity as it may require against the costs, expenses, and liabilities to be incurred therein or thereby, and the Trustee or the Securities Administrator, as appropriate, for 60 days after its receipt of such notice, request and offer of indemnity shall have neglected or refused to institute any such action, suit or proceeding; it being understood and intended, and being expressly covenanted by each Certificateholder with every other Certificateholder and the Trustee, that no one or more Holders of Certificates shall have any right in any manner whatever by virtue or by availing itself or themselves of any provisions of this Agreement to affect, disturb or prejudice the rights of the Holders of any other of the Certificates, or to obtain or seek to obtain priority over or preference to any other such Holder or to enforce any right under this Agreement, except in the manner herein provided and for the common benefit of all Certificateholders. For the protection and enforcement of the provisions of this Section 12.08, each and every Certificateholder, the Trustee or the Securities Administrator shall be entitled to such relief as can be given either at law or in equity.

Section 12.09 Inspection and Audit Rights. The Master Servicer agrees that, on reasonable prior notice, it will permit any representative of the Depositor or the Trustee during the Master Servicer’s normal business hours, to examine all the books of account, records, reports and other papers of the Master Servicer relating to the Mortgage Loans, to make copies and extracts therefrom, to cause such books to be audited by independent certified public accountants selected by the Depositor or the Trustee and to discuss its affairs, finances and accounts relating to such Mortgage Loans with its officers, employees and independent public accountants (and by this provision the Master Servicer hereby authorizes such accountants to discuss with such representative such affairs, finances and accounts), all at such reasonable times and as often as may be reasonably requested. Any out-of-pocket expense incident to the exercise by the Depositor or the Trustee of any right under this Section 12.09 shall be borne by the party requesting such inspection, subject to such party’s right to reimbursement hereunder (in the case of the Trustee, pursuant to Section 10.05 hereof).

ASSET-BACKED CERTIFICATE

SERIES 2005-AC4

evidencing a fractional undivided interest in the distributions allocable to the Class A Certificates with respect to a Trust Fund consisting primarily of a pool of conventional one- to four-family fixed interest rate mortgage loans sold by BEAR STEARNS ASSET BACKED SECURITIES I LLC.

This Certificate is payable solely from the assets of the Trust Fund, and does not represent an obligation of or interest in Bear Stearns Asset Backed Securities I LLC, the Master Servicer, the Trustee or the Securities Administrator referred to below or any of their affiliates or any other person. Neither this Certificate nor the underlying Mortgage Loans are guaranteed or insured by any governmental entity or by Bear Stearns Asset Backed Securities I LLC, the Master Servicer, the Trustee or the Securities Administrator or any of their affiliates or any other person. None of Bear Stearns Asset Backed Securities I LLC, the Master Servicer or any of their affiliates will have any obligation with respect to any certificate or other obligation secured by or payable from payments on the Certificates.

Association will act as master servicer of the Mortgage Loans (the “Master Servicer,” which term includes any successors thereto under the Agreement referred to below). The Trust Fund was created pursuant to the Pooling and Servicing Agreement, dated as of the Cut-off Date specified above (the “Agreement”), among BSABS I, as depositor (the “Depositor”), EMC Mortgage Corporation as seller and company, Wells Fargo Bank, National Association, as Master Servicer and securities administrator (the “Securities Administrator”) and U.S. Bank National Association, as trustee (the “Trustee”), a summary of certain of the pertinent provisions of which is set forth hereafter. To the extent not defined herein, capitalized terms used herein shall have the meaning ascribed to them in the Agreement. This Certificate is issued under and is subject to the terms, provisions and conditions of the Agreement, to which Agreement the Holder of this Certificate by virtue of its acceptance hereof assents and by which such Holder is bound.

Interest on this Certificate will accrue during the month prior to the month in which a Distribution Date (as hereinafter defined) occurs on the Certificate Principal Balance hereof at a per annum rate equal to the Pass-Through Rate set forth above. The Trustee will distribute on the 25th day of each month, or, if such 25th day is not a Business Day, the immediately following Business Day (each, a “Distribution Date”), commencing on the First Distribution Date specified above, to the Person in whose name this Certificate is registered at the close of business on the last day (or if such last day is not a Business Day, the Business Day immediately preceding such last day) of the calendar month immediately preceding the month in which the Distribution Date occurs, an amount equal to the product of the Percentage Interest evidenced by this Certificate and the amount (of interest and principal, if any) required to be distributed to the Holders of Certificates of the same Class as this Certificate. The Assumed Final Distribution Date is the Distribution Date in the month following the latest scheduled maturity date of any Mortgage Loan and is not likely to be the date on which the Certificate Principal Balance of this Class of Certificates will be reduced to zero.

Distributions on this Certificate will be made by the Trustee by check mailed to the address of the Person entitled thereto as such name and address shall appear on the Certificate Register or, if such Person so requests by notifying the Trustee in writing as specified in the Agreement. Notwithstanding the above, the final distribution on this Certificate will be made after due notice by the Trustee of the pendency of such distribution and only upon presentation and surrender of this Certificate at the office or agency appointed by the Trustee for that purpose and designated in such notice. The initial Certificate Principal Balance of this Certificate is set forth above. The Certificate Principal Balance hereof will be reduced to the extent of distributions allocable to principal hereon.

This Certificate is one of a duly authorized issue of Certificates designated as set forth on the face hereof (the “Certificates”). The Certificates, in the aggregate, evidence the entire beneficial ownership interest in the Trust Fund formed pursuant to the Agreement.

The Certificateholder, by its acceptance of this Certificate, agrees that it will look solely to the Trust Fund for payment hereunder and that the Trustee is not liable to the Certificateholders for any amount payable under this Certificate or the Agreement or, except as expressly provided in the Agreement, subject to any liability under the Agreement.

This Certificate does not purport to summarize the Agreement and reference is made to the Agreement for the interests, rights and limitations of rights, benefits, obligations and duties evidenced hereby, and the rights, duties and immunities of the Trustee.

The Agreement permits, with certain exceptions therein provided, the amendment thereof and the modification of the rights and obligations of the Depositor and the rights of the Certificateholders under the Agreement from time to time by the parties thereto with the consent of the Holders of the Class or Classes of Certificates affected thereby evidencing over 50% of the Voting Rights of such Class or Classes. Any such consent by the Holder of this Certificate shall be conclusive and binding on such Holder and upon all future Holders of this Certificate and of any Certificate issued upon the transfer hereof or in lieu hereof whether or not notation of such consent is made upon this Certificate. The Agreement also permits the amendment thereof, in certain limited circumstances, without the consent of the Holders of any of the Certificates.

As provided in the Agreement and subject to certain limitations therein set forth, the transfer of this Certificate is registrable with the Trustee upon surrender of this Certificate for registration of transfer at the offices or agencies maintained by the Trustee for such purposes, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Trustee duly executed by the Holder hereof or such Holder’s attorney duly authorized in writing, and thereupon one or more new Certificates in authorized denominations representing a like aggregate Percentage Interest will be issued to the designated transferee.

The Certificates are issuable only as registered Certificates without coupons in the Classes and denominations specified in the Agreement. As provided in the Agreement and subject to certain limitations therein set forth, this Certificate is exchangeable for one or more new Certificates evidencing the same Class and in the same aggregate Percentage Interest, as requested by the Holder surrendering the same.

No service charge will be made to the Certificateholders for any such registration of transfer, but the Trustee may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. The Depositor, the Master Servicer, the Trustee and any agent of any of them may treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and none of Depositor, the Master Servicer, the Trustee or any such agent shall be affected by notice to the contrary.

The obligations created by the Agreement and the Trust Fund created thereby (other than the obligations to make payments to Certificateholders with respect to the termination of the Agreement) shall terminate upon the earlier of (i) the later of (A) the maturity or other liquidation (or Advance with respect thereto) of the last Mortgage Loan remaining in the Trust Fund and disposition of all property acquired upon foreclosure or deed in lieu of foreclosure of any Mortgage Loan and (B) the remittance of all funds due under the Agreement, or (ii) the optional repurchase by the party named in the Agreement of all the Mortgage Loans and other assets of the Trust Fund in accordance with the terms of the Agreement. Such optional repurchase may be made only on or after the earlier of (i) the first Distribution Date on which the aggregate Stated Principal Balance of the Mortgage Loans is less than or equal to 20% of the aggregate Stated Principal Balance of the Mortgage Loans as of the Cut-off Date and (ii) the Distribution Date in June 2015. The exercise of such right will effect the early retirement of the

Certificates. In no event, however, will the Trust Fund created by the Agreement continue beyond the expiration of 21 years after the death of certain persons identified in the Agreement.

Unless this Certificate has been countersigned by an authorized signatory of the Trustee 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 Trustee has caused this Certificate to be duly executed.

evidencing a fractional undivided interest in the distributions allocable to the Class M-[1][2][3] Certificates with respect to a Trust Fund consisting primarily of a pool of conventional one- to four-family fixed interest rate mortgage loans sold by BEAR STEARNS ASSET BACKED SECURITIES I LLC.

This certifies that Cede & Co. is the registered owner of the Percentage Interest evidenced hereby in the beneficial ownership interest of Certificates of the same Class as this Certificate in a trust (the “Trust Fund”) generally consisting of conventional first lien, fixed rate mortgage loans secured by one- to four- family residences (collectively, the “Mortgage Loans”) sold by Bear Stearns Asset Backed Securities I LLC (“BSABS I”). The Mortgage Loans were sold by EMC Mortgage Corporation (“EMC”) to BSABS I. Wells Fargo Bank, National Association will act as master servicer of the Mortgage Loans (the “Master Servicer,” which term includes any successors thereto under the Agreement referred to below). The Trust Fund was created pursuant to the Pooling and Servicing Agreement dated as of the Cut-off Date

specified above (the “Agreement”), among BSABS I, as depositor (the “Depositor”), EMC Mortgage Corporation as seller and company, Wells Fargo Bank, National Association, as Master Servicer and securities administrator (the “Securities Administrator”) and U.S. Bank National Association, as trustee (the “Trustee”), a summary of certain of the pertinent provisions of which is set forth hereafter. To the extent not defined herein, capitalized terms used herein shall have the meaning ascribed to them in the Agreement. This Certificate is issued under and is subject to the terms, provisions and conditions of the Agreement, to which Agreement the Holder of this Certificate by virtue of its acceptance hereof assents and by which such Holder is bound.

Interest on this Certificate will accrue from and including the 25^th day of the calendar month preceding the month in which a Distribution Date (as hereinafter defined) occurs to and including the 24^th day of the calendar month in which that Distribution Date occurs on the Certificate Principal Balance hereof at a per annum rate equal to the Pass-Through Rate set forth above. The Trustee will distribute on the 25th day of each month, or, if such 25th day is not a Business Day, the immediately following Business Day (each, a “Distribution Date”), commencing on the First Distribution Date specified above, to the Person in whose name this Certificate is registered at the close of business on the Business Day immediately preceding such Distribution Date, an amount equal to the product of the Percentage Interest evidenced by this Certificate and the amount (of interest and principal, if any) required to be distributed to the Holders of Certificates of the same Class as this Certificate. The Assumed Final Distribution Date is the Distribution Date in the month following the latest scheduled maturity date of any Mortgage Loan and is not likely to be the date on which the Certificate Principal Balance of this Class of Certificates will be reduced to zero.

Each beneficial owner of a Certificate or any interest therein shall be deemed to have represented, by virtue of its acquisition or holding of that certificate or interest therein, that either (i) it is not a Plan or investing with “Plan Assets”, (ii) it has acquired and is holding such certificate in reliance on the Exemption, and that it understands that there are certain conditions to the availability of the Exemption, including that the certificate must be rated, at the time of purchase, not lower than “BBB-“ (or its equivalent) by S&P, Fitch Ratings or Moody’s, and the certificate is so rated or (iii) (1) it is an insurance company, (2) the source of funds used to acquire or hold the certificate or interest therein is an “insurance company general account,” as such term is defined in Prohibited Transaction Class Exemption (“PTCE”) 95-60, and (3) the conditions in Sections I and III of PTCE 95-60 have been satisfied.

No service charge will be made to the Certificateholders for any such registration of transfer, but the Trustee may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. The Depositor, the Master Servicer, the Trustee and any agent of any of them may treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and none of the Depositor, the Master Servicer, the Trustee or any such agent shall be affected by notice to the contrary.

any Mortgage Loan and (B) the remittance of all funds due under the Agreement, or (ii) the optional repurchase by the party named in the Agreement of all the Mortgage Loans and other assets of the Trust Fund in accordance with the terms of the Agreement. Such optional repurchase may be made only on or after the earlier of (i) the first Distribution Date on which the aggregate Stated Principal Balance of the Mortgage Loans is less than or equal to 20% of the aggregate Stated Principal Balance of the Mortgage Loans as of the Cut-off Date and (ii) the Distribution Date in June 2015. The exercise of such right will effect the early retirement of the Certificates. In no event, however, will the Trust Fund created by the Agreement continue beyond the expiration of 21 years after the death of certain persons identified in the Agreement.

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

unless subsequently registered under the Act and any applicable state securities or “Blue Sky” laws or an exemption from the registration requirements of the Act and any applicable state securities or “Blue Sky” laws is available;

WITNESSETH THAT:

WHEREAS, the Depositor, the Seller, the Master Servicer and the Trustee have entered into a Pooling and Servicing Agreement, dated as of June 1, 2005, relating to the issuance of Bear Stearns Asset Backed Securities I Trust 2005-AC4, Asset-Backed Certificates, Series 2005-AC4 (as in effect on the date of this Agreement, the “Original Pooling and Servicing Agreement,” and as amended and supplemented from time to time, the “Pooling and Servicing Agreement”); and

WHEREAS, the Custodian has agreed to act as agent for the Trustee for the purposes of receiving and holding certain documents and other instruments delivered by the Depositor, the Seller or the Master Servicer under the Pooling and Servicing Agreement and the Servicers under their respective Servicing Agreements, all upon the terms and conditions and subject to the limitations hereinafter set forth;

NOW, THEREFORE, in consideration of the premises and the mutual covenants and agreements hereinafter set forth, the Trustee, the Depositor, the Seller, the Master Servicer and the Custodian hereby agree as follows:

ARTICLE I

DEFINITIONS

Capitalized terms used in this Agreement and not defined herein shall have the meanings assigned in the Original Pooling and Servicing Agreement, unless otherwise required by the context herein.

ARTICLE II

CUSTODY OF MORTGAGE DOCUMENTS

Section 2.1 Custodian to Act as Agent: Acceptance of Mortgage Files. The Custodian, as the duly appointed custodial agent of the Trustee for these purposes, acknowledges (subject to any exceptions noted in the Initial Certification referred to in Section 2.3(a) receipt of the Mortgage Files relating to the Mortgage Loans identified on the schedule attached hereto (the “Mortgage Files”) and declares that it holds and will hold such Mortgage Files as agent for the Trustee, in trust, for the use and benefit of all present and future Certificateholders.

Section 2.2 Recordation of Assignments. If any Mortgage File includes one or more assignments of Mortgage that have not been recorded pursuant to the provisions of Section 2.01 of the Pooling and Servicing Agreement and the related Mortgage Loan is not a MOM Loan or the related Mortgaged Properties are located in jurisdictions specifically excluded by the Opinion of Counsel delivered to the Trustee pursuant to Section 2.01 of the Pooling and Servicing Agreement, each such assignment shall be delivered by the Custodian to the Seller for the purpose of recording it in the appropriate public office for real property records, and the Seller, at no expense to the Custodian, shall promptly cause to be recorded in the appropriate public office for real property records each such assignment of Mortgage and, upon receipt thereof from such public office, shall return each such assignment of Mortgage to the Custodian.

Section 2.3

Review of Mortgage Files.

(a) On or prior to the Closing Date, in accordance with Section 2.02 of the Pooling and Servicing Agreement, the Custodian shall deliver to the Seller and the Trustee an Initial Certification in the form annexed hereto as Exhibit One evidencing receipt (subject to any exceptions noted therein) of a Mortgage File for each of the Mortgage Loans listed on the Schedule attached hereto (the “Mortgage Loan Schedule”).

(b) Within 90 days of the Closing Date, the Custodian agrees, for the benefit of Certificateholders, to review, in accordance with the provisions of Section 2.02 of the Pooling and Servicing Agreement, each such document, and shall deliver to the Seller and the Trustee an Interim Certification in the form annexed hereto as Exhibit Two to the effect that all such documents have been executed and received and that such documents relate to the Mortgage Loans identified on the Mortgage Loan Schedule, except for any exceptions listed on Schedule A attached to such Interim Certification. The Custodian shall be under no duty or obligation to inspect, review or examine said documents, instruments, certificates or other papers to determine that the same are genuine, enforceable, or appropriate for the represented purpose or that they have actually been recorded or that they are other than what they purport to be on their face.

(c) Not later than 180 days after the Closing Date, the Custodian shall review the Mortgage Files as provided in Section 2.02 of the Pooling and Servicing Agreement and deliver to the Seller and the Trustee a Final Certification in the form annexed hereto as Exhibit Three evidencing the completeness of the Mortgage Files.

(d) In reviewing the Mortgage Files as provided herein and in the Pooling and Servicing Agreement, the Custodian shall make no representation as to and shall not be

responsible to verify (i) the validity, legality, enforceability, due authorization, recordability, sufficiency or genuineness of any of the documents included in any Mortgage File or (ii) the collectibility, insurability, effectiveness or suitability of any of the documents in any Mortgage File.

Upon receipt of written request from the Trustee, the Custodian shall as soon as practicable supply the Trustee with a list of all of the documents relating to the Mortgage Loans missing from the Mortgage Files.

Section 2.4 Notification of Breaches of Representations and Warranties. Upon discovery by the Custodian of a breach of any representation or warranty made by the Depositor as set forth in the Pooling and Servicing Agreement with respect to a Mortgage Loan relating to a Mortgage File, the Custodian shall give prompt written notice to the Depositor, the related Servicer and the Trustee.

Section 2.5 Custodian to Cooperate: Release of Mortgage Files. Upon receipt of written notice from the Trustee that the Seller has repurchased a Mortgage Loan pursuant to Article II of the Pooling and Servicing Agreement, and a request for release (a “Request for Release”) confirming that the purchase price therefore has been deposited in the Master Servicer Collection Account or the Distribution Account, then the Custodian agrees to promptly release to the Seller the related Mortgage File.

Upon the Custodian’s receipt of a Request for Release substantially in the form of Exhibit G to the Pooling and Servicing Agreement signed by a Servicing Officer of a Servicer, stating that it has received payment in full of a Mortgage Loan or that payment in full will be escrowed in a manner customary for such purposes, the Custodian agrees promptly to release to the Servicer, the related Mortgage File. The Depositor shall deliver to the Custodian and the Custodian agrees to review in accordance with the provisions of their Agreement the Mortgage Note and other documents constituting the Mortgage File with respect to any Replacement Mortgage Loan.

From time to time as is appropriate for the servicing or foreclosure of any Mortgage Loan, including, for this purpose, collection under any Primary Insurance Policy or LPMI Policy, the Company or the related Servicer, as applicable, shall deliver to the Custodian a Request for Release signed by a Servicing Officer requesting that possession of all of the Mortgage File be released to the Company or the related Servicer, as applicable, and certifying as to the reason for such release and that such release will not invalidate any insurance coverage provided in respect of the Mortgage Loan under any of the Insurance Policies.

Section 3.4 Custodian May Resign; Trustee May Remove Custodian. The Custodian may resign from the obligations and duties hereby imposed upon it as such obligations and duties relate to its acting as Custodian of the Mortgage Loans.

Any resignation or removal of the Custodian and appointment of a successor Custodian pursuant to any of the provisions of this Section 3.4 shall become effective upon acceptance of appointment by the successor Custodian.

Custodian 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.
