The Seller has entered into this Agreement in consideration for the purchase of the Mortgage Loans by the Depositor 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 any such transfer and assignment, the Depositor has delivered to or caused to be delivered to, and deposited with, the Custodian 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 "JPMorgan Chase Bank, as Trustee for certificateholders of Bear Stearns Asset Backed Securities Trust 2005-SD1, Asset Backed Certificates, Series 2005-SD1, without recourse", or (B) in the case of a Mortgage Loan registered on the MERS(R) 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 registered on the MERS(R) System, 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, in recordable form, with respect to each Mortgage Loan in the name of "JPMorgan Chase Bank, as Trustee for certificateholders of Bear Stearns Asset Backed Securities Trust 2005-SD1, Asset Backed Certificates, Series 2005-SD1" or in blank, (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 35 (vi) originals or copies of all available assumption, modification or substitution agreements, if any; provided, however, that the assignment of the Mortgage to the Trustee will not be required to be submitted for recording with respect to any Mortgage Loan: (a) if the Trustee and the Custodian shall have received an Opinion of Counsel addressed to the Trustee stating that in such counsel's opinion, the recordation of the assignment to the Trustee of the Mortgage securing a particular Mortgage Note is not necessary to transfer to the assignee thereof all the benefits and security provided by the Mortgage as against the related assignor or any creditor of such assignor, and the Mortgage will continue to secure the Mortgage Note to the same extent as if the Mortgage Note and Mortgage had not been assigned and delivered, (b) such recordation is not required by the Rating Agencies or (c) if MERS is identified on the Mortgage or on a properly recorded assignment of the Mortgage as the mortgagee of record solely as nominee for the Seller and its successors and assigns; and provided, further, however, that in lieu of the foregoing, the Depositor may deliver, or cause to be delivered, 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, or cause to be delivered, a true copy thereof with a certification by the applicable Servicer 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 J, the Depositor may deliver, or cause to be delivered, a lost note affidavit (or a blanket lost note affidavit covering some or all of the Mortgage Loans in Exhibit J) and a copy of the original note, if available;

In the case of the documents referred to in clause (x) above, the Depositor shall deliver, or cause to be delivered, such documents to the 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. In the event that the Seller, the Depositor or the Master Servicer gives written notice to the Trustee (a) that recording of the assignment of the Mortgage to the Trustee is required to protect the right, title and interest of the Trustee on behalf of the Certificateholders in and to any Mortgage Loan, (b) a court recharacterizes the sale of the Mortgage Loans as a financing, or (c) as a result of any change in or amendment to the laws of a State in which recording was not effected or any applicable political subdivision thereof, or any change in official position regarding application or interpretation of such laws, including a holding by a court of competent jurisdiction, such recording is so required, the Seller shall submit or cause to be submitted for recording as specified above or, should the Seller fail to perform such obligations, the Trustee shall cause each such previously unrecorded assignment to be submitted for recording as specified above at the expense of the Trust pursuant to Section 9.05. In the event a Mortgage File is released to the Master Servicer or a Servicer as a result of 36 the Master Servicer's or a Servicer's having completed a Request for Release, the Trustee shall, if not so completed, complete, or cause the Custodian to complete, the assignment of the related Mortgage in the manner specified in clause (iii) above. In connection with the assignment of any Mortgage Loans registered on the MERS(R) System, the Seller further agrees that it will cause, at the Seller's own expense, within 30 days after the Closing Date, the MERS(R) 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, (b) the code in the field "Pool Field" which identifies the series of the Certificates issued in connection with such Mortgage Loans and (c) a code that provides the Custodian with access to such Mortgage Loans. The Seller further agrees that it will not, and will not permit 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. Since the mortgage loans permitted to be purchased pursuant to this Agreement are limited to (i) the Mortgage Loans purchased hereunder on the Closing Date and (ii) any Replacement Mortgage Loans purchased hereafter pursuant to the provisions of this Agreement, and the Seller has made the representations and warranties contained herein with respect to all such Mortgage Loans, including, a representation and warranty contained in Section 2.03(b)(vii)(S) of this Agreement, that, as of the Closing Date or date of substitution, as applicable, no Mortgage Loan is a "High-Cost Home Loan" as defined in the New Jersey Home Ownership Security Act of 2002 (the "New Jersey Act"), a "High-Cost Home Loan" as defined in the New Mexico Home Loan Protection Act (the "New Mexico Act"), a "High Cost Home Mortgage Loan" under the Massachusetts Predatory Home Loan Practices Act of 2004 (the "Massachusetts Act") or a "High-Cost Home Loan" under the Indiana High Cost Home Loan Law of 2005 (the "Indiana Act"), it is agreed and understood by the Depositor, the Seller and the Trustee that it is not intended that any mortgage loan be purchased hereunder that is a "High-Cost Home Loan" as defined in the New Jersey Act, a "High-Cost Home Loan" as defined in the New Mexico Act, a "High Cost Home Mortgage Loan" as defined in the Massachusetts Act or a "High-Cost Home Loan" as defined in the Indiana Act. Section 2.02. Acceptance of the Mortgage Loans. (a) The Trustee acknowledges receipt based on receipt by the Custodian of, subject to the further review and the exceptions the Custodian notes pursuant to the procedures described below, the documents (or certified copies thereof) delivered to the Custodian pursuant to Section 2.01 and declares that it holds and will continue to hold directly or through the Custodian those documents and any amendments, replacements or supplements thereto and all other assets of the Trust Fund delivered to the Custodian on its behalf in trust for the use and benefit of all present and future Holders of the Certificates. On the Closing Date, the Custodian will deliver an initial certification in the form annexed as Exhibit One to the Custodial Agreement 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 in lieu thereof. No later than 90 days after the Closing Date, the Custodian agrees pursuant to the Custodial Agreement, for the benefit of the Certificateholders, to review each Mortgage File delivered to it and to execute and deliver, or cause to be executed and delivered, to the Seller and to the Trustee an interim certification substantially in the form annexed as Exhibit Two to the Custodial Agreement. In conducting such review, the Custodian on behalf of the Trustee will ascertain whether all required documents have been executed and received and whether those documents relate, determined on the basis of the Mortgagor 37 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 clauses (iv) and (vi) of the fourth paragraph of Section 2.01, such obligations shall extend only to documents actually delivered pursuant to such clauses). In performing any such review, the Custodian on behalf of the Trustee and in accordance with the Custodial Agreement 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 Custodian 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 Custodian shall include such information in the exception report attached to such interim certification. 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 and the Custodian an Opinion of Counsel, addressed to the Trustee and the Custodian, at the Seller's expense, to the effect that such defect does not materially or adversely affect the interests of Certificateholders in such Mortgage Loan within 90 days from the date of notice from the Custodian 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 Custodian 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 Custodian on behalf of the Trustee and in accordance with the Custodial Agreement 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 to the Trustee, a final certification substantially in the form annexed as Exhibit Three to the Custodial Agreement. In conducting such review, the Custodian will ascertain whether each document required to be recorded has been returned from the recording office with evidence of recording thereon and the Custodian 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 clauses (iv) and (vi) of the fourth paragraph of Section 2.01, such obligations shall extend only to documents actually delivered pursuant to such clauses). If the Custodian 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 Custodian 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 and the Custodian an Opinion of Counsel, addressed to the Trustee and the Custodian, at the Seller's expense, to the effect that such defect does not materially or adversely affect the interests of Certificateholders in such Mortgage Loan within 90 days from the date of notice from the Custodian 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 Custodian, 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 38 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 Trustee for deposit in the Distribution 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 Distribution Account and receipt of a Request for Release, the Trustee will release or notify the Custodian which, upon receipt of such notice from the Trustee, shall 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 Distribution Account was made or if the Custodian is then acting, the date on which notice of the deposit of the Purchase Price into the Distribution Account was received by the Custodian from the Trustee. 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 remedy respecting such defect available to the Certificateholders or to the Trustee on their behalf. (d) The Seller shall deliver to the Trustee or upon its direction to the Custodian, and the Trustee agrees to accept or to cause the Custodian to accept, the Mortgage Note and other documents constituting the Mortgage File with respect to any Replacement Mortgage Loan, which 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. (e) Until all amounts distributable in respect of the Certificates have been distributed in full and the Master Servicer has otherwise fulfilled its respective obligations under this Agreement, the Trustee, or the Custodian acting on its behalf, shall retain possession and custody of each Mortgage File in accordance with and subject to the terms and conditions of this Agreement.

(B) No Mortgage Loan is delinquent 61 or more days; and the Seller has not advanced funds, or induced, solicited or knowingly received any advance of funds from a party other than the owner of the Mortgaged Property subject to the Mortgage, directly or indirectly, for the payment of any amount required under any Mortgage Loan. 41 (C) Except with respect to taxes, insurance and other amounts previously advanced by a Servicer with respect to any Mortgage Loan, to the best of Seller's knowledge, there are no delinquent taxes, water charges, sewer rents, assessments, insurance premiums, leasehold payments, including assessments payable in future installments, or other outstanding charges affecting the related Mortgaged Property. (D) The terms of the Mortgage Note and the Mortgage have not been impaired, waived, altered or modified in any respect, except by written instruments which in the case of the Mortgage Loans are in the Mortgage File and have been or will be recorded, if necessary to protect the interests of the Trustee, and which have been or will be delivered to the Trustee, all in accordance with this Agreement. The substance of any such waiver, alteration or modification has been approved by the title insurer, to the extent required by the related policy. No Mortgagor has been released, in whole or in part, except in connection with an assumption agreement approved by the title insurer, to the extent required by the policy, and which assumption agreement in the case of the Mortgage Loans is part of the Mortgage File. (E) The Mortgage Note and the Mortgage are not subject to any right of rescission, set-off, counterclaim or defense, including the defense of usury, nor will the operation of any of the terms of the Mortgage Note and the Mortgage, or the exercise of any right thereunder, render the Mortgage unenforceable, in whole or in part, or subject to any right of rescission, set-off, counterclaim or defense, including the defense of usury and no such right of rescission, set-off, counterclaim or defense has been asserted with respect thereto. (F) All buildings upon, or comprising part of, the Mortgaged Property are insured by an insurer acceptable to Fannie Mae and Freddie Mac against loss by fire, hazards of extended coverage and such other hazards as are customary in the area where the Mortgaged Property is located, and such insurer is licensed to do business in the state where the Mortgaged Property is located. All such insurance policies contain a standard mortgagee clause naming the Originator, its successors and assigns as mortgagee and Seller has received no notice that all premiums thereon have not been paid. If upon origination of the Mortgage Loan, the Mortgaged Property was, or was subsequently deemed to be, in an area identified in the Federal Register by the Federal Emergency Management Agency as having special flood hazards (and such flood insurance has been made available), which require under applicable law that a flood insurance policy meeting the requirements of the current guidelines of the Federal Insurance Administration (or any successor thereto) be obtained, such flood insurance policy is in effect which policy is with a generally acceptable carrier in an amount representing coverage not less than the least of (A) the Stated Principal Balance of the related Mortgage Loan (together with, in the case of a Mortgage Loan that is not a first priority lien, the outstanding principal balance of all related liens that are prior to the applicable lien of such Mortgage Loan), (B) the minimum amount required to compensate for damage or loss on a replacement cost basis, or (C) the maximum amount of insurance that is available under the Flood Disaster Protection Act of 1973. The Mortgage obligates the Mortgagor thereunder to maintain all such insurance at Mortgagor's cost and expense and, on the Mortgagor's failure to do so, authorizes the holder of the Mortgage to maintain such insurance at Mortgagor's cost and expense and to obtain reimbursement therefor from the Mortgagor. (G) None of the Mortgage Loans are (a) Mortgage Loans subject to 12 CFR Part 226.31, 12 CFR Part 226.32 or 226.34 of Regulation Z, the regulation implementing TILA, which implements the Home Ownership and Equity Protection Act of 1994, as amended, (b) classified and/or defined, as a "high cost", "threshold", "predatory" or "covered" loan (or a similarly classified loan using different terminology under a law imposing additional legal liability for mortgage loans having high interest rates, points and/or fees) under any other applicable state, federal or local law including, but not limited to, the States of New York, North Carolina, Arkansas, Kentucky, New Mexico, Illinois and 42 Oklahoma, (c) Mortgage Loans governed by the Georgia Fair Lending Act, if such Mortgage Loan was originated on or after October 1, 2002 through May 6, 2003 or (d) Mortgage Loans subject to the New Jersey Home Ownership Security Act of 2002 (the "New Jersey Act"), unless such Mortgage Loan is a (1) "Home Loan" as defined in the New Jersey Act that is a first lien Mortgage Loan, which is not a "High Cost Home Loan" as defined in the New Jersey Act or (2) "Covered Home Loan" as defined in the New Jersey Act that is a first lien purchase money Mortgage Loan, which is not a High Cost Home Loan under the New Jersey Act. In addition to and notwithstanding anything to the contrary herein, no Mortgage Loan for which the Mortgaged Property is located in New Jersey is a Home Loan as defined in the Act that was made, arranged, or assigned by a person selling either a manufactured home or home improvements to the Mortgaged Property or was made by an originator to whom the Mortgagor was referred by any such seller. Each Mortgage Loan at the time it was made otherwise complied in all material respects with any and all requirements of any federal, state or local law including, but not limited to, all predatory lending laws, usury, truth in lending, real estate settlement procedures (including the Real Estate Settlement Procedures Act of 1974, as amended, consumer credit protection, equal credit opportunity or disclosure laws applicable to such Mortgage Loan. (H) The Mortgage has not been satisfied, canceled, subordinated, or rescinded, in whole or in part, and the Mortgaged Property has not been released from the lien of the Mortgage, in whole or in part, nor has any instrument been executed that would effect any such release, cancellation, subordination or rescission. (I) The Mortgage is a valid, existing and enforceable first lien on the Mortgaged Property, including all improvements on the Mortgaged Property, if any, subject only to (1) the lien of current real property taxes and assessments not yet due and payable, (2) covenants, conditions and restrictions, rights of way, easements and other matters of the public record as of the date of recording being acceptable to mortgage lending institutions generally and specifically referred to in the lender's title insurance policy delivered to the Originator of the Mortgage Loan and which do not adversely affect the Appraised Value of the Mortgaged Property, (3) if applicable, in the case of a Mortgage that is a second priority lien, the first lien on the Mortgaged Property identified in the related Mortgage File, and (4) other matters to which like properties are commonly subject which do not materially interfere with the benefits of the security intended to be provided by the Mortgage. The Seller has full right to sell and assign the Mortgage to the Depositor. None of the Mortgages related to the Mortgage Loans is a second lien. (J) The Mortgage Note and the related Mortgage are genuine and each is the legal, valid and binding obligation of the maker thereof, enforceable in accordance with its terms, except as the enforceability thereof may be limited by bankruptcy, insolvency or reorganization or general principles of equity. (K) All parties to the Mortgage Note and the Mortgage had the legal capacity to enter into the Mortgage Loan transaction and to execute and deliver the Mortgage Note and the Mortgage, and the Mortgage Note and the Mortgage have been duly and properly executed by such parties. (L) The proceeds of the Mortgage Loan have been fully disbursed and there is no requirement for future advances thereunder and any and all requirements as to completion of any on-site or off-site improvement and as to disbursements of any escrow funds therefor have been complied with. All costs, fees and expenses incurred in making or closing the Mortgage Loan and the recording of the Mortgage were paid, and the Mortgagor is not entitled to any refund of any amounts paid or due under the Mortgage Note or Mortgage. (M) Immediately prior to the conveyance of the Mortgage Loans by the Seller to the Depositor hereunder, the Seller was the sole owner and holder of the Mortgage Loan and either serviced 43 the Mortgage Loan itself or the Mortgage Loan was being serviced pursuant to a Servicing Agreement with the Servicer indicated on the Mortgage Loan Schedule; the related Originator or the Seller or the applicable Servicer was the custodian of the related escrow account, if applicable; the Mortgage Loan had neither been assigned nor pledged, and the Seller had good and marketable title thereto, and had full right to transfer and sell the Mortgage Loan and the related servicing rights to the Depositor free and clear of any encumbrance, equity, lien, pledge, charge, claim or security interest subject to the applicable Servicing Agreement, if any, and had full right and authority subject to no interest or participation of, or agreement with, any other party, to sell and assign the Mortgage Loan and the related servicing rights to the Depositor pursuant to the terms of this Agreement. (N) All parties which have had any interest in the Mortgage, whether as mortgagee, assignee, pledgee or otherwise, are (or, during the period in which they held and disposed of such interest, were) (1) in compliance with any and all applicable licensing requirements of the laws of the state wherein the Mortgaged Property is located, and (2) organized under the laws of such state, qualified to do business in such state, a federal savings and loan association or national bank having principal offices in such state or not deemed to be doing business in such state under applicable law. (0) The Mortgage Loan is covered by an ALTA lender's title insurance policy or equivalent form acceptable to the Department of Housing and Urban Development, or any successor thereto, and qualified to do business in the jurisdiction where the Mortgaged Property is located, insuring (subject to the exceptions contained in clause (I) above) the Seller (as assignee), its successors and assigns as to the first or, if applicable, more junior priority lien of the Mortgage in the original principal amount of the Mortgage Loan and against any loss by reason of the invalidity or unenforceability of the lien resulting from the provisions of the Mortgage Note and/or Mortgage providing for adjustment in the Mortgage Rate and monthly payment. Additionally, such lender's title insurance policy affirmatively insures ingress and egress, and against encroachments by or upon the Mortgaged Property or any interest therein. With respect to each Mortgage Loan, the Seller (as assignee) is the sole insured of such lender's title insurance policy, and such lender's title insurance policy is in full force and effect. No claims have been made under such lender's title insurance policy, and no prior holder of the related Mortgage, including the Seller in the case of a Mortgage Loan, has done, by act or omission, anything which would impair the coverage of such lender's title insurance policy. (P) Except as provided in clause (B), immediately prior to the Cut-off Date, there was no default, breach, violation or event of acceleration existing under the Mortgage or the Mortgage Note and there was no event which, with the passage of time or with notice and the expiration of any grace or cure period, would constitute a default, breach, violation or event of acceleration, and the Seller has not waived any default, breach, violation or event of acceleration. (Q) There are no mechanics' or similar liens or claims which have been filed for work, labor or material (and no rights are outstanding that under law could give rise to such lien) affecting the related Mortgaged Property which are or may be liens prior to or equal with, the lien of the related Mortgage. (R) All improvements which were considered in any appraisal which was used in determining the Appraised Value of the related Mortgaged Property lay wholly within the boundaries and building restriction lines of the Mortgaged Property, and no improvements on adjoining properties encroach upon the Mortgaged Property. (S) No Mortgage Loan is a "High Cost Home Loan" as defined in the New Jersey Home Ownership Security Act of 2002, a "High Cost Home Loan" as defined in the New Mexico Home Loan Protection Act, a "High Cost Home Mortgage Loan" as defined in the Massachusetts Predatory 44 Home Loan Practices Act of 2004 or a "High-Cost Home Loan" as defined in the Indiana High Cost Home Loan Law of 2005. (T) The origination, servicing and collection practices with respect to each Mortgage Note and Mortgage including, the establishment, maintenance and servicing of the escrow accounts and escrow payments, if any, since origination, have been conducted in all respects in accordance with the terms of Mortgage Note and in compliance with all applicable laws and regulations and, unless otherwise required by law or Fannie Mae/Freddie Mac standard, in accordance with the proper, prudent and customary practices in the mortgage origination and servicing business. With respect to the escrow accounts and escrow payments, if any, and a Mortgage Loan all such payments are in the possession or under the control of the Seller (including pursuant to a Servicing Agreement) and there exists no deficiencies in connection therewith for which customary arrangements for repayment thereof have not been made. All Mortgage Rate adjustments have been made in strict compliance with state and federal law and the terms of the related Mortgage Note. Any interest required to be paid pursuant to state and local law has been properly paid and credited. (U) The Mortgaged Property is free of material damage and waste and there is no proceeding pending for the total or partial condemnation thereof. (V) The Mortgage contains customary and enforceable provisions to render the rights and remedies of the holder thereof adequate for the realization against the Mortgaged Property of the benefits of the security intended to be provided thereby, including, (1) in the case of a Mortgage designated as a deed of trust, by trustee's sale, and (2) otherwise by judicial foreclosure. There is no other exemption available to the Mortgagor which would interfere with the right to sell the Mortgaged Property at a trustee's sale or the right to foreclose the Mortgage. The Mortgagor has not notified the Seller and the Seller has no knowledge of any relief requested or allowed to the Mortgagor under the Relief Act. (W) The Mortgage Note is not and has not been secured by any collateral except the lien of the applicable Mortgage. (X) [Reserved]. (Y) In the event the Mortgage constitutes a deed of trust, a trustee, duly qualified under applicable law to serve as such, has been properly designated and currently so serves and is named in the Mortgage, and no fees or expenses are or will become payable by the Certificateholders to the trustee under the deed of trust, except in connection with a trustee's sale after default by the Mortgagor. (Z) No Mortgage Loan contains a permanent or temporary "buydown" provision. The Mortgage Loan is not a graduated payment mortgage loan and the Mortgage Loan does not have a shared appreciation or other contingent interest feature. (AA) The Mortgagor has received all disclosure materials required by applicable law with respect to the making of the Mortgage Loan. The Seller has maintained or caused to be maintained all such statements in the Mortgage File. (BB) No Mortgage Loan was made in connection with the construction or rehabilitation of a Mortgaged Property. (CC) To the best of Seller's knowledge, the Mortgaged Property is lawfully occupied under applicable law and all inspections, licenses and certificates required to be made or issued with respect to all occupied portions of the Mortgaged Property and, with respect to the use and occupancy of 45 the same, including but not limited to certificates of occupancy, have been made or obtained from the appropriate authorities. (DD) The assignment of Mortgage with respect to a Mortgage Loan (other than a Mortgage Loan registered on the MERS(R) system) is in recordable form and is acceptable for recording under the laws of the jurisdiction in which the Mortgaged Property is located. (EE) Any future advances made to the Mortgagor prior to the Cut-off Date have been consolidated with the outstanding principal amount secured by the Mortgage, and the secured principal amount, as consolidated, bears a single interest rate and single repayment term. The lien of the Mortgage securing the consolidated principal amount is expressly insured as having first priority, by a title insurance policy, an endorsement to the policy insuring the mortgagee's consolidated interest or by other title evidence acceptable to Fannie Mae and Freddie Mac. The consolidated principal amount does not exceed the original principal amount of the Mortgage Loan. (FF) With respect to any Mortgage Loan that bears, or will upon conversion from a fixed rate bear, interest at an adjustable rate, on each Interest Adjustment Date, the Mortgage Rate has been adjusted to equal the respective Index plus the respective Gross Margin (subject to standard rounding conventions), subject to the Periodic Rate Cap, the Maximum Lifetime Mortgage Rate and the Minimum Lifetime Mortgage Rate, if any, as set forth in the related Mortgage Note. (GG) Without exception in either Group, the Mortgaged Property consists of a single parcel of real property with or without a detached single family residence erected thereon, or an individual condominium unit, or a cooperative, or a 2-4 family dwelling, or an individual unit in a planned unit development as defined by Fannie Mae or a manufactured dwelling which conforms with Fannie Mae and Freddie Mac requirements regarding such dwellings, or a townhouse, each structure of which is permanently affixed to the Mortgaged Property, and is legally classified as real estate. (HH) [Reserved]. (II) 85.83% of the Group II Mortgage Loans (by Cut-off Date Principal Balance) are Hybrid Mortgage Loans in their fixed rate period. None of the Mortgage Loans contain a provision allowing the Mortgagor to convert an adjustable rate Mortgage Loan to a fixed rate Mortgage Loan. The principal and interest due on each Mortgage Loan is calculated pursuant to the standard amortization method (30/360 day interest accrual). 0.03% and 0% of the Mortgage Loans (by cut-off Date Principal Balance) in Group I and Group II, respectively, are Simple Interest Loans. (JJ) Each Mortgage Loan at the time of origination was underwritten in general in accordance with guidelines not inconsistent with the guidelines set forth in the Prospectus Supplement and generally accepted prime or sub-prime credit underwriting guidelines. (KK) No error, omission, misrepresentation, fraud or similar occurrence with respect to a Mortgage Loan has taken place on the part of the Seller or the related Originator. (LL) None of the Mortgage Loans is a "High Cost Loan" or "Covered Loan" as defined in the current Standard & Poor's LEVELS(R) Glossary which is now Version 5.6 Revised, Appendix E. (MM) No more than 0% and 11.15% of the Mortgage Loans, by Cut-off Date Principal Balance, in Group I and Group II, respectively, provided for negative amortization. 46 (c) Upon discovery by any of the parties hereto of a breach of a representation or warranty set forth in Section 2.03(b)(vii) that materially and adversely affects the interests of the Certificateholders in any Mortgage Loan, the party discovering such breach shall give prompt written notice thereof to the other parties. The Seller hereby covenants with respect to the representations and warranties set forth in Section 2.03(b)(vii), 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 Master Servicer 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 Master Servicer 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 2.03(b)(vii) 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 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, except with respect to any Simple Interest Loans, distributions to Certificateholders will include the Scheduled Payment due on any Deleted Mortgage Loan for the related Due Period (and with respect to any Simple Interest Loans, payments of principal actually received during such Due Period) and thereafter the Seller shall be entitled to retain all amounts received in respect of such Deleted Mortgage Loan. The Master Servicer 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 Master Servicer 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 2.03(b)(vii) with respect to such Mortgage Loan. Upon any such substitution and the deposit to the Master Servicer Collection Account, of the amount required to be deposited therein in connection with such substitution as described in the following paragraph, the Trustee shall release to the Seller the Mortgage File relating to such Deleted Mortgage Loan and held for the benefit of the Certificateholders and 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. 47 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, except the actual payment received with respect to any Simple Interest Loans) 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 in the Master Servicer Collection Account pursuant to Section 3.08 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 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 remedy against the Seller respecting such breach available to Certificateholders, the Depositor or the Trustee. (d) The representations and warranties set forth in Section 2.03 hereof shall survive delivery of the respective Mortgage Files to the Trustee for the benefit of the Certificateholders. Section 2.03(A) Assignment of Interests in the Servicing Agreements. To the extent not provided for in the related Assumption Agreements, the Seller hereby assigns to the Depositor who concurrently with the execution and delivery of this Agreement assigns to the Trustee, on behalf of the Certificateholders, all of their respective right, title and interest in the Servicing Agreements and, if applicable, the Assumption Agreements, including but not limited to the Seller's rights pursuant to the Servicing Agreements (noting that the Seller has retained the right in the event of breach of the representations, warranties and covenants, if any, with respect to the Mortgage Loans of WFB under the related Servicing Agreement to enforce the provisions thereof and to seek all or any available remedies); provided that the Seller shall retain the right to terminate WFB without cause as set forth in Section 11.02 of the related Servicing Agreement. 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 a 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. 48 (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 certificate of formation or limited liability company agreement 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 free and clear of all liens, claims and encumbrances, 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 Custodian on behalf of the Trustee to the Trustee. 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. 49 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, with a copy to the Custodian, an Opinion of Counsel, addressed to the Trustee, 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 either 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, with a copy to the Custodian, 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 Master Servicer, the Custodian or the Trustee that any Mortgage Loan does not constitute a "qualified mortgage" within the meaning of section 860G(a)(3) of the Code, the party discovering such fact shall promptly (and in any event within 5 Business Days of discovery) give written notice thereof to the other parties. In connection therewith, the Trustee 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 shall reconvey to the Seller the Mortgage Loan to be released pursuant hereto in the same manner, and on the same terms and conditions, as it would a Mortgage Loan repurchased for breach of a representation or warranty contained in Section 2.03. Section 2.06. Authentication and Delivery of Certificates. The Trustee acknowledges the transfer and assignment to it of the Trust Fund and, concurrently with such transfer and assignment, has executed, authenticated 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, to the end that the interests of the Holders of the Certificates may be adequately and effectively protected. Section 2.07. Covenants of the Master Servicer and the EMC Servicer. The Master Servicer covenants to the Depositor, the Securities Administrator and the Trustee, and the EMC Servicer covenants to the Master Servicer, as follows: (a) it shall comply in the performance of its obligations under this Agreement; (b) no written information, certificate of an officer, statement furnished in writing (other than annual compliance certificates and annual accountants' reports of the Servicers delivered by the Master Servicer pursuant to Section 3.18) or written report prepared by the Master Servicer or the EMC Servicer, as applicable, pursuant to this Agreement and delivered, the case of the Master Servicer, to the Securities Administrator, the Depositor, any affiliate of the 50 Depositor or the Trustee or, in the case of the EMC Servicer, to the Master Servicer, will contain any untrue statement of a material fact or omit to state a material fact necessary to make the information, certificate, statement or report not misleading; and (c) it shall (in the case of the Master Servicer, only in its capacity as successor servicer pursuant to a Servicing Agreement) accurately and fully provide information regarding payment performance of the Mortgagors to the nationally recognized credit repositories, to the extent such reporting remains customary and prudent in the servicing of mortgage loans similar to the Mortgage Loans. Nothing in this Section shall derogate from the obligation of the Master Servicer or the EMC Servicer to observe any applicable law prohibiting disclosure of information regarding the Mortgagors and the failure of the Master Servicer or the EMC Servicer to provide access as provided in this Section as a result of such obligation shall not constitute a breach of this Section. Section 2.08. Lost Mortgage Notes Indemnity With respect to each Mortgage Loan for which the Seller has delivered a lost note affidavit in lieu of an original Mortgage Note, the Seller does hereby agree to defend, indemnify, and hold harmless the Trust Fund and the Trustee, from and against any and all losses or damages, together with all reasonable costs, charges and expenses (whether or not a lawsuit is filed), incurred as a result of (i) the inability to enforce the related Mortgage Note according to its terms, (ii) any claim, demand, suit, cause of action or proceeding by a third party arising out of a Servicer's, the Master Servicer's or the Trustee's inability to enforce the related Mortgage Note according to its terms due to the lack of an original Mortgage Note, or (iii) the inability to receive any related Insurance Proceeds, Liquidation Proceeds or other amounts due to the lack of an original Mortgage Note. Upon demand from a Servicer, the Master Servicer or the Trustee, the Seller shall deposit all amounts constituting lost principal with respect to such Mortgage Loan into the Master Servicer Collection Account to be treated as a Principal Prepayment, and reimburse such Servicer, the Master Servicer or the Trustee, as applicable, for all costs and expenses incurred in connection with such lost Mortgage Note. 51 ARTICLE III. ADMINISTRATION AND MASTER SERVICING OF MORTGAGE LOANS Section 3.01. The Master Servicer. The Master Servicer shall supervise, monitor and oversee the obligation of the Servicers to service and administer their respective Mortgage Loans in accordance with the terms of the applicable Servicing Agreement and shall have full power and authority to do any and all things which it may deem necessary or desirable in connection with such master servicing and administration. In performing its obligations hereunder, the Master Servicer shall act in a manner consistent with Accepted Master Servicing Practices. Furthermore, the Master Servicer shall oversee and consult with each such Servicer as necessary from time-to-time to carry out the Master Servicer's obligations hereunder, shall receive and review all reports, information and other data provided to the Master Servicer by each such Servicer and shall cause each such Servicer to perform and observe the covenants, obligations and conditions to be performed or observed by such Servicer under the applicable Servicing Agreement. The Master Servicer shall independently and separately monitor each such 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 such Servicers' and the Master Servicer's records, and based on such reconciled and corrected information, prepare the statements specified in Section 5.04(c) 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 each such Servicer to its Protected Account pursuant to the applicable Servicing Agreement. Section 3.02. REMIC-Related Covenants. For as long as each REMIC shall exist, the Trustee shall act in accordance herewith to assure continuing treatment of such REMIC as a REMIC, and the Trustee shall comply with any directions of the Seller, the Depositor, any Servicer or the Master Servicer to assure such continuing treatment. In particular, the Trustee shall not (a) sell or permit the sale of all or any portion of the 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 and prepared at the expense of the Trust Fund; and (b) other than with respect to a substitution pursuant to a Servicing Agreement or Section 2.04 of this Agreement, as applicable, accept any contribution to any REMIC after the Startup Day without receipt of a REMIC Opinion addressed to the Trustee. Section 3.03. Monitoring of Servicers. (a) The Master Servicer shall be responsible for reporting to the Securities Administrator, the Depositor and the Seller the compliance by each Servicer with its duties under the related Servicing Agreement. In the review of each such Servicer's activities, the Master Servicer may rely upon an officer's certificate of such Servicer with regard to such Servicer's compliance with the terms of its Servicing Agreement. In the event that the Master Servicer, in its judgment, determines that any such Servicer should be terminated in accordance with its Servicing Agreement, or that a notice should be sent pursuant to such Servicing Agreement with respect to the occurrence of an event that, unless cured, would constitute grounds for such termination, the Master Servicer shall notify the Seller, the Depositor, the EMC Servicer and the Trustee thereof and the Master Servicer shall issue such notice or take such other action as it deems appropriate. 52 (b) Subject to the preceding paragraph, the Master Servicer, on behalf of the Trustee and the Certificateholders, shall enforce the obligations of each Servicer under the related Servicing Agreement, and, in the event that any such Servicer fails to perform its obligations in accordance with the related Servicing Agreement, then either the EMC Servicer (if such defaulting Servicer is WFB) or the Master Servicer (if such defaulting Servicer is any Servicer other than WFB), shall terminate the rights and obligations of the defaulting Servicer thereunder and act as successor servicer of the related Mortgage Loans or cause the Trustee to enter into a new Servicing Agreement with a successor servicer selected by either the EMC Servicer (if the defaulting Servicer is WFB) or by the Master Servicer (if the defaulting Servicer is any Servicer other than WFB) (which new Servicing Agreement shall, in any case, have terms generally in accordance with the terms of the terminated Servicing Agreement); 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 Servicing Agreements and the pursuit of other appropriate remedies, shall be in such form and carried out to such an extent and at such time as the Master Servicer, in its good faith business judgment, would require were it the owner of the related Mortgage Loans. Except as contemplated by subsection (c) below, the Master Servicer shall pay the costs of such enforcement at its own expense, provided that the Master Servicer shall not be required to prosecute or defend any legal action except to the extent that the Master Servicer shall have received reasonable indemnity for its costs and expenses in pursuing such action. Without limiting the generality of the foregoing, WFB shall reimburse the EMC Servicer for all Termination Costs associated with a termination of WFB as Servicer. To the extent that any Termination Costs with respect to WFB are not fully and timely reimbursed by WFB, the EMC Servicer shall be entitled to reimbursement of such Termination Costs from its Protected Account. (c) The EMC Servicer shall reimburse the Master Servicer for the costs and expenses of the Master Servicer related to the termination of the EMC Servicer, appointment of a successor servicer or the transfer and assumption of servicing by the Master Servicer with respect to 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 EMC Servicer as a result of an event of default by such Servicer and (ii) all costs and expenses associated with the complete transfer of servicing, including all servicing files and all servicing data and the completion, correction or manipulation of such servicing data as may be required by the successor servicer to correct any errors or insufficiencies in the servicing data or otherwise to enable the successor servicer to service the Mortgage Loans in accordance with the related Servicing Agreement. To the extent that any Termination Costs with respect to the EMC Servicer or any other terminated servicer pursuant to the related Servicing Agreement are not fully and timely reimbursed by the EMC Servicer or such other terminated Servicer, as applicable, the Master Servicer shall be entitled to reimbursement of such Termination Costs from the Master Servicer Collection Account. (d) The Master Servicer shall require each Servicer to comply with the remittance requirements and other obligations set forth in the related Servicing Agreement, including any related Assumption Agreement. The Master Servicer shall enforce the obligation of each Servicer pursuant to the related Servicing Agreement to provide it with the annual officer's certificate of compliance and annual independent accountants' servicing reports, as well as back-up certifications to each Master Servicer Certification pursuant to Section 3.18. (e) If the Master Servicer or the EMC Servicer assumes the servicing with respect to any of the Mortgage Loans, it will not assume liability for the representations and warranties of any Servicer that it replaces. 53 Section 3.04. Successor Master Servicer and Subservicing Agreements. In the event that, pursuant to Section 8.01 hereof, the Trustee or any other Person shall become Successor Master Servicer, such Successor Master Servicer may, at its option, succeed to any rights and obligations of the predecessor Master Servicer under any subservicing agreement in accordance with the terms thereof; provided that such Successor Master Servicer shall not incur any liability or have any obligations in its capacity as servicer under a subservicing agreement arising prior to the date of such succession unless it expressly elects to succeed to the rights and obligations of the predecessor Master Servicer thereunder; and the predecessor Master Servicer shall not thereby be relieved of any liability or obligations under the subservicing agreement arising prior to the date of such succession. Such predecessor Master Servicer shall, upon request of the Trustee, but at the expense of such predecessor Master Servicer, deliver to the assuming party all documents and records relating to each subservicing agreement and the Mortgage Loans then being serviced thereunder and an accounting of amounts collected held by it and otherwise use its best efforts to effect the orderly and efficient transfer of the subservicing agreement to the assuming party. Section 3.05. 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 X hereof, to do any and all things that it may deem necessary or desirable in connection with the master servicing and administration of such 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 the related Servicing Agreement, including any related Assumption Agreement. The Trustee shall furnish the Master Servicer, upon written request from a Servicing Officer, with any powers of attorney empowering it or any 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 applicable Servicing Agreement and this Agreement, and the Trustee shall execute and deliver such other documents, as the Master Servicer may request, to enable it 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 the use or misuse of any such powers of attorney by the Master Servicer or any 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 9.11 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. The Trustee and the Securities Administrator shall each execute and deliver to 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 related Mortgage; (iii) obtain a deficiency judgment against the Mortgagor; or (iv) enforce any other rights or remedies provided by the Mortgage Note or related Mortgage or otherwise available at law or equity. 54 Section 3.06. Due-on-Sale Clauses; Assumption Agreements. To the extent provided in the applicable Servicing Agreement, for any Mortgage Loans that contain enforceable due-on-sale clauses, the Master Servicer shall cause the related Servicer to enforce such clauses in accordance with the applicable Servicing Agreement. If applicable law prohibits the enforcement of a due-on-sale clause or such clause is otherwise not enforced in accordance with such applicable Servicing Agreement, and, as a consequence, a Mortgage Loan is assumed, the original Mortgagor may be released from liability in accordance with the applicable Servicing Agreement. Section 3.07. Release of Mortgage Files. (a) Upon becoming aware of the payment in full of any Mortgage Loan, or the receipt by the Master Servicer or any Servicer of a notification that payment in full has been escrowed in a manner customary for such purposes for payment to Certificateholders on the next Distribution Date, such Servicer will, or if it does not, the Master Servicer may, if required under the applicable Servicing Agreement, promptly furnish to the Custodian on behalf of the Trustee two copies of a certification substantially in the form of Exhibit H 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 Master Servicer (as successor servicer) or the applicable Servicer pursuant to its Servicing Agreement have been or will be so deposited or escrowed) and shall request that the Custodian on behalf of the Trustee deliver to the Master Servicer or the applicable Servicer, as appropriate, 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 Master Servicer or the applicable Servicer, as appropriate, and neither the Custodian nor the Trustee shall have any further responsibility with regard to such Mortgage File. Upon any such payment in full, the Master Servicer and each Servicer is authorized, to give, as agent for the Trustee, as the mortgagee under the Mortgage that secured the Mortgage Loan, an instrument of satisfaction (or assignment of mortgage without recourse) regarding the Mortgaged Property subject to the Mortgage, which instrument of satisfaction or assignment, as the case may be, shall be delivered to the Person or Persons entitled thereto against receipt therefor of such payment, it being understood and agreed that no expenses incurred in connection with such instrument of satisfaction or assignment, as the case may be, shall be chargeable to the Protected Account. (b) From time to time and as appropriate for the servicing or foreclosure of any Mortgage Loan and in accordance with the applicable Servicing Agreement, the Trustee shall execute such documents as shall be prepared and furnished to the Trustee by a Servicer or the Master Servicer (in form reasonably acceptable to the Trustee) and as are necessary to the prosecution of any such proceedings. The Custodian on behalf of the Trustee shall, upon the request of a Servicer or the Master Servicer, and delivery to the Custodian on behalf of the Trustee, of two copies of a request for release signed by a Servicing Officer substantially in the form of Exhibit H (or in a mutually agreeable electronic format which will, in lieu of a signature on its face, originate from a Servicing Officer), release the related Mortgage File held in its possession or control to the Servicer or the Master Servicer, as applicable. Such trust receipt shall obligate the Servicer or the Master Servicer to return the Mortgage File to the Custodian on behalf of the Trustee, when the need therefor by the Servicer or the Master Servicer no longer exists unless the Mortgage Loan shall be liquidated, in which case, upon receipt of a certificate of a Servicing Officer similar to that hereinabove specified, the Mortgage File shall be released by the Custodian on behalf of the Trustee, to the Servicer or the Master Servicer. 55 Section 3.08. Documents, Records and Funds in Possession of the Master Servicer To Be Held for Trustee. (a) The Master Servicer and each Servicer (to the extent required by the related Servicing Agreement) shall transmit to the Trustee or Custodian such documents and instruments coming into the possession of the Master Servicer or such Servicer from time to time as are required by the terms hereof, or in the case of the Servicers, in accordance with the applicable Servicing Agreement, to be delivered to the Trustee or the Custodian. Any funds received by the Master Servicer or a Servicer in respect of any Mortgage Loan or which otherwise are collected by the Master Servicer or a 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, in the case of the Master Servicer, the Master Servicer's right to retain or withdraw from the Master Servicer Collection Account the Master Servicing Fee and other amounts provided in this Agreement and to the right of each Servicer to retain its Servicing Fee and other amounts as provided in the applicable Servicing Agreement. The Master Servicer shall, and, to the extent provided in the applicable Servicing Agreement, shall cause each Servicer to, provide access to information and documentation regarding the Mortgage Loans to the Trustee, the Securities Administrator and their respective 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 and each 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 applicable Servicing Agreement. Section 3.09. Maintenance of Hazard Insurance. (a) For each Mortgage Loan, the Master Servicer shall enforce any obligation of a Servicer under the related Servicing Agreement to maintain or cause to be maintained hazard insurance in accordance with the provisions of the related Servicing Agreement. (b) Pursuant to Section 4.01, any amounts collected by the Master Servicer, or by any Servicer, 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 the applicable Servicing Agreement) shall be deposited into the Master Servicer Collection Account, subject to withdrawal pursuant to Section 4.03. Any cost incurred by the Master Servicer or any such 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 or such Servicer pursuant to Section 4.03. 56 Section 3.10. Presentment of Claims and Collection of Proceeds. The Master Servicer shall (to the extent provided in the applicable Servicing Agreement) cause the related 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 Insurance Policies. Any proceeds disbursed to the Master Servicer (or disbursed to a Servicer and remitted to the Master Servicer) in respect of such Insurance Policies 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 3.11. Maintenance of the Primary Mortgage Insurance Policies. (a) The Master Servicer shall not take, or permit any Servicer, to the extent such action is prohibited under the applicable 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 or such Servicer, would have been covered thereunder. The Master Servicer shall use its best efforts to cause each such Servicer (to the extent required under 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 in accordance with the provisions of the related Servicing Agreement. The Master Servicer shall not, and shall not permit any Servicer, to the extent required under 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 the related Servicing Agreement. (b) The Master Servicer agrees to present, or to cause each Servicer to the extent required under 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. Pursuant to Section 4.01, any amounts collected by the Master Servicer or any such Servicer under any Primary Mortgage Insurance Policies shall be deposited in the Master Servicer Collection Account, subject to withdrawal pursuant to Section 4.03. Section 3.12. Custodian to Retain Possession of Certain Insurance Policies and Documents. The Custodian shall, on behalf of the Trustee, retain possession and custody of the originals (to the extent available) of any Primary Mortgage Insurance Policies, or certificate of insurance if applicable, and any certificates of renewal as to the foregoing as may be issued from time to time. Until all amounts distributable in respect of the Certificates have been distributed in full and the Master Servicer otherwise has fulfilled its obligations under this Agreement, the Custodian, on behalf of the Trustee, shall also retain possession and custody of each Mortgage File in accordance with and subject to the terms and conditions of this Agreement and the Custodial Agreement. The Master Servicer shall promptly deliver or cause to be delivered to the Custodian, on behalf of the Trustee, upon the execution or receipt thereof the originals of any Primary Mortgage Insurance Policies, any certificates of renewal, and such other documents or instruments that constitute portions of the Mortgage File that come into the possession of the Master Servicer from time to time. 57 Section 3.13. Realization Upon Defaulted Mortgage Loans. The Master Servicer shall cause each Servicer to the extent required under the related Servicing Agreement, to foreclose upon, repossess or otherwise comparably convert the ownership of Mortgaged Properties securing such of the Mortgage Loans as come into and continue in default and as to which no satisfactory arrangements can be made for collection of delinquent payments, all in accordance with the terms of the applicable Servicing Agreement, including any related Assumption Agreement. Section 3.14. Compensation for the Servicers and the Master Servicer. Servicing compensation in the form of any prepayment charges and penalties, assumption fees, tax service fees, fees for statement of account payoff or late payment charges collected by any Servicer shall be retained by such Servicer and shall not be deposited in the Master Servicer Collection Account. In accordance with Sections 4.02(b) and 4.03, the Master Servicer shall be entitled to pay itself the Master Servicing Fee in respect of remittances from Servicers prior to deposit in the Master Servicer Collection Account or to withdraw such portion of the Master Servicing Fee from the Master Servicer Collection Account. The Master Servicer shall be required to pay all expenses incurred by it in connection with its activities hereunder and shall not be entitled to reimbursement therefor except as specifically provided in this Agreement. Pursuant to Article IV, all income and gain realized from any investment of funds in the Distribution Account and the Master Servicer Collection Account shall be for the benefit of the Master Servicer. Section 3.15. REO Property. (a) In the event the Trust Fund acquires ownership of any REO Property in respect of any related 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 Master Servicer shall, to the extent provided in the applicable Servicing Agreement, cause the applicable Servicer to sell any REO Property as expeditiously as possible and in accordance with the provisions of this Agreement and the related Servicing Agreement. Pursuant to its efforts to sell such REO Property, the Master Servicer shall cause such applicable Servicer to protect and conserve such REO Property in the manner and to the extent required by the applicable Servicing Agreement, subject to the REMIC Provisions. (b) The Master Servicer shall, to the extent required by the related Servicing Agreement, cause the applicable Servicer to deposit all funds collected and received in connection with the operation of any REO Property into the related Protected Account. (c) The Master Servicer and such applicable Servicer, upon the final disposition of any REO Property, 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 3.16. Annual Officer's Certificate as to Compliance. (a) The Master Servicer shall deliver to the Depositor, the Trustee and the Rating Agencies by March 1, 2006, and by March 1 of each year thereafter, in each case for the immediately preceding calendar year, an Officer's Certificate, certifying that with respect to the period ending on such calendar year end: (i) such Servicing Officer has reviewed the activities of the Master Servicer during the preceding calendar year or portion thereof and its performance under this Agreement, (ii) to the best of 58 such Servicing Officer's knowledge, based on such review, the Master Servicer has performed and fulfilled its duties, responsibilities and obligations under this Agreement in all material respects throughout such year, or, if there has been a default in the fulfillment of any such duties, responsibilities or obligations, specifying each such default known to such Servicing Officer and the nature and status thereof and (iii) nothing has come to the attention of such Servicing Officer to lead such Servicing Officer to believe that any Servicer has failed to perform any of its duties, responsibilities and obligations under its Servicing Agreement in all material respects throughout such year, or, if there has been a material default in the performance or fulfillment of any such duties, responsibilities or obligations, specifying each such default known to such Servicing Officer and the nature and status thereof. (b) Copies of such statements shall be provided by the Trustee to any Certificateholder upon request at the Master Servicer's expense, provided that such statement shall have been delivered to the Trustee. Section 3.17. Annual Independent Accountant's Servicing Report. If the Master Servicer has, during the course of any calendar year, directly serviced any of the Mortgage Loans, the Master Servicer, at its expense, shall cause a nationally recognized firm of independent certified public accountants to furnish a statement to the Trustee, the Rating Agencies and the Seller by March 1, 2006, and by March 1 of each year thereafter, in each case for the immediately preceding calendar year, to the effect that, with respect to the most recently ended calendar year, such firm has examined certain records and documents relating to the Master Servicer's performance of its servicing obligations under this Agreement and pooling and servicing and trust agreements in material respects similar to this Agreement and to each other and that, on the basis of such examination conducted substantially in compliance with the audit program for mortgages serviced for Freddie Mac or the Uniform Single Attestation Program for Mortgage Bankers, such firm is of the opinion that the Master Servicer's activities have been conducted in compliance with this Agreement, or that such examination has disclosed no material items of noncompliance except for (i) such exceptions as such firm believes to be immaterial, (ii) such other exceptions as are set forth in such statement and (iii) such exceptions that the Uniform Single Attestation Program for Mortgage Bankers or the Audit Program for Mortgages Serviced by Freddie Mac requires it to report. Copies of such statements shall be provided to any Certificateholder, upon request, by the Master Servicer, or by the Trustee at the expense of the Master Servicer if the Master Servicer shall fail to provide such copies. If any such report discloses exceptions that are material, the Master Servicer shall advise the Trustee whether such exceptions have been or are susceptible of cure, and will take prompt action to do so.

Within 15 days after each Distribution Date, the Securities Administrator shall, in accordance with industry standards, file with the Commission via the Electronic Data Gathering and Retrieval System ("EDGAR"), a Form 8-K with a copy of the statement to the Trustee. Prior to January 30 in each year, the Securities Administrator shall, in accordance with industry standards and only if instructed by the Depositor, file a Form 15 Suspension Notice with respect to the Trust Fund, if applicable. Prior to (i) March 15, 2006 and (ii) unless and until a Form 15 Suspension Notice shall have been filed, prior to March 15 of each year thereafter, the Master Servicer shall provide the Securities Administrator with a Master Servicer Certification, together with a copy of the annual independent accountant's servicing report and annual statement of compliance of each Servicer, in each case, required to be delivered pursuant to its Servicing Agreement, and, if applicable, the annual independent accountant's servicing report and annual statement of compliance to be delivered by the Master Servicer pursuant to Sections 3.16 and 3.17.

Such assignment shall be an assignment outright and not for security. The EMC Servicer shall thereupon own such Mortgage Loan, and all security and documents, free of any further obligation to the Trustee or the Certificateholders with respect thereto. Notwithstanding the foregoing, any such optional right of repurchase by the EMC Servicer hereunder with respect to a delinquent Mortgage Loan shall, if unexercised, terminate on the earlier of (i) the date on which such delinquency has been cured or (ii) the last Business Day of such Fiscal Quarter immediately following the date on which such Mortgage Loan became 91 days delinquent, provided however, that such optional right of repurchase shall be reinstated if (a) in the case of clause (i), the related Mortgage Loan shall thereafter again have become 91 or more days delinquent and (b) in the case of clause (ii), such delinquency shall have been subsequently cured and the related Mortgage Loan shall thereafter again become 91 or more days delinquent in any subsequent Fiscal Quarter.

Holders of such Certificates will not be entitled to any payment in respect of Current Interest on the amount of such increases for an Interest Accrual Period preceding the Distribution Date on which such increase occurs. Section 5.05. Monthly Statements to Certificateholders.

To the extent timely received from the Securities Administrator, the Trustee will also make monthly statements available each month to Certificateholders and the Yield Maintenance Provider via the Trustee's internet website. The trustee's internet website will initially be located at www.jpmorgan.com/sfr. Assistance in using the Trustee's website service can be obtained by calling the Trustee's customer service desk at (877) 722-1095. Parties that are unable to use the above distribution options are entitled to have a paper copy mailed to them via first class mail by calling the 76 Securities Administrator's customer service desk and indicating such. The Securities Administrator may change the way monthly statements are distributed in order to make such distributions more convenient or more accessible to the above parties. (b) The Securities Administrator's responsibility for making the above information available to the Certificateholders is limited to the availability, timeliness and accuracy of the information derived from the Master Servicer and the EMC Servicer. The Securities Administrator will make available a copy of each statement provided pursuant to this Section 5.05 to each Rating Agency. (c) Within a reasonable period of time after the end of each calendar year, the Securities Administrator will prepare and the Trustee will provide to the EMC Servicer, and upon request to each Person who at any time during the calendar year was a Certificateholder, a statement containing the information set forth in clauses (a)(i) and (a)(ii) of this Section 5.05 aggregated for such calendar year or applicable portion thereof during which such Person was a Certificateholder. Such obligation of the Trustee shall be deemed to have been satisfied to the extent that substantially comparable information shall be provided by the Trustee pursuant to any requirements of the Code as from time to time in effect. (d) Upon filing with the Internal Revenue Service, the Securities Administrator shall furnish to the Holders of the Residual Certificates the applicable Form 1066 and each applicable Form 1066Q and shall respond promptly to written requests made not more frequently than quarterly by any Holder of a Residual Certificate with respect to the following matters: (i) The original projected principal and interest cash flows on the Closing Date on each Class of regular and residual interests created hereunder and on the Mortgage Loans, based on the Prepayment Assumption; (ii) The projected remaining principal and interest cash flows as of the end of any calendar quarter with respect to each Class of regular and residual interests created hereunder and the Mortgage Loans, based on the Prepayment Assumption; (iii) The applicable Prepayment Assumption and any interest rate assumptions used in determining the projected principal and interest cash flows described above; (iv) The original issue discount (or, in the case of the Mortgage Loans, market discount) or premium accrued or amortized through the end of such calendar quarter with respect to each Class of regular or residual interests created hereunder and to the Mortgage Loans, together with each constant yield to maturity used in computing the same; (v) The treatment of losses realized with respect to the Mortgage Loans or the regular interests created hereunder, including the timing and amount of any cancellation of indebtedness income of a REMIC with respect to such regular interests or bad debt deductions claimed with respect to the Mortgage Loans; (vi) The amount and timing of any non-interest expenses of a REMIC; and (vii) Any taxes (including penalties and interest) imposed on the REMIC, including, without limitation, taxes on "prohibited transactions," "contributions" or "net income from foreclosure property" or state or local income or franchise taxes. The information pursuant to clauses (i), (ii), (iii) and (iv) above shall be provided by the Depositor pursuant to Section 9.12. 77 Section 5.06. REMIC Designations and Allocations. (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 Master Servicer Collection Account, the Distribution Account, any REO Property, and any proceeds of the foregoing. (b) REMIC I will be evidenced by (x) the Class I-A-1, Class I-A-2, Class I-A-3, Class I-M-1, Class I-M-2, Class I-M-3, Class I-M-4, Class I-M-5, Class I-M-6, Class I-B, Class II-A, Class II-M-1, Class II-M-2, Class II-M-3 and Class II-B (the "REMIC I Regular Interests"), which are hereby designated as the "regular interests" in REMIC I and will be uncertificated and non-transferable and (y) the Class R-1 Certificate, which is hereby designated as the single "residual interest" in REMIC I (the REMIC I Regular Interests, together with the Class R-1 Certificate, the "REMIC I Certificates"). The REMIC I Regular Interests shall be recorded on the records of REMIC I as being issued to and held by the Trustee on behalf of REMIC II. Principal shall be payable to, and shortfalls, losses and prepayments are allocable to, the REMIC I Regular Interests as such amounts are payable and allocable to the Certificates with the corresponding designations. The REMIC I Certificates will have the following designations, initial principal balances, pass-through rates and allocations of interest:

_______________ (1) The pass-through rate on this REMIC I Regular Interest shall at any time of determination equal the weighted average of the Net Mortgage Rates of the Mortgage Loans of the related Group. However, the Pass-Through Rate due on the first Distribution Date will be a fixed rate equal to the weighted average of the Net Mortgage Rates of the Mortgage Loans of the related Group. (2) Except as provided in note (3) below, interest will be allocated among the Class I-A-1, Class I-A-2, Class I-A-3, Class I-M-1, Class I-M-2, Class I-M-3, Class I-M-4, Class I-M-5, Class I-M-6 and Class I-B, Class II- 78 A, Class II-M-1, Class II-M-2, Class II-M-3 and Class II-B REMIC I Certificates in the same proportion as interest is payable on the Certificates with the corresponding designations. (3) Any interest with respect to these REMIC I Regular Interests in excess of the weighted average coupon of the REMIC I Regular Interests of the same related Group, where each such REMIC I Regular Interests is first subject to a cap and floor equal to the Pass-Through Rate of the Certificate with the corresponding designation will be allocated to the Class B-IO Certificates of the corresponding related Group. In addition, an amount equal to the Initial Overcollateralization Amount with respect to each Group shall be allocated to the corresponding Class B-IO Certificates on the first Distribution Date. However, the Class B-IO Certificates shall be subordinated to the extent provided in Section 5.04. (4) On each Distribution Date, amounts, if any, remaining in REMIC I after payments of interest and principal, as designated above, will be distributed to the Class R-1 Certificate. (c) The Adjustable Rate Certificates (exclusive of any rights such Certificates may have to receive, and payments of, Basis Risk Shortfall Carry Forward Amounts and Yield Maintenance Amounts) and the Class B-IO Certificates (exclusive of any rights or obligations associated with these Certificates in connection with the treatment of the Holders of such Certificates as the owners, for federal income tax purposes, of the Yield Maintenance Account and the payments of Basis Risk Shortfall Carry Forward Amounts, as described in Section 5.06(e) below) are hereby designated as "regular interests" with respect to REMIC II (the "REMIC II Regular Interests") and the Class R-2 Certificate is hereby designated as the single "residual interest" with respect to REMIC II. On each Distribution Date, amounts, if any, remaining in REMIC II after payments of interest and principal as designated herein shall be distributed to the Class R-2 Certificate. The terms of the REMIC II Regular Interests are set out in Section 6.01. (d) For federal income tax purposes, each of REMIC I and REMIC II shall have a tax year that is a calendar year and shall report income on an accrual basis. (e) Payments of Basis Risk Shortfall Carry Forward Amounts and Yield Maintenance Payments shall be deemed to be made to the holders of the Class B-IO Certificate of the related Group with respect to which such payments were made, who will be the owners of such amounts (on a pro rata basis based upon their Percentage Interest in such Class) for federal income tax purposes. The Class I-B-IO Certificateholders will be considered to pay such amounts to the Class I-A-1, Class I-A-2, Class I-A-3, Class I-M-1, Class I-M-2, Class I-M-3, Class I-M-4, Class I-M-5, Class I-M-6 and Class I-B, and the Class II-B-IO Certificateholders will be considered to pay such amounts to the Class II-A, Class II-M-1, Class II-M-2, Class II-M-3 and Class II-B Certificates, as and to the extent appropriate, pursuant to a notional principal contract. Section 5.07. Supplemental Interest Reserve Fund; WAC Excess. (a) On the Closing Date, the holders of the Class B-IO Certificates will deposit, or cause to be deposited, into the Supplemental Interest Reserve Fund, $10,000. On each Distribution Date as to which there is WAC Excess to the extent not paid under Section 5.04(a), the Trustee has been directed to, and shall therefore, deposit into the Supplemental Interest Reserve Fund an amount equal to the WAC Excess to the extent of the Class I-B-IO Distribution Amount or Class II-B-IO Distribution Amount, as applicable, which is payable pursuant to Section 5.04(a). If no WAC Excess is payable on a Distribution Date, the Trustee shall deposit into the Supplemental Interest Reserve Fund on behalf of the Class B-IO Certificateholders an amount such that when added to other amounts already on deposit in the fund, the aggregate amount on deposit therein is equal to $10,000. For federal and state income tax purposes, the Class B-IO Certificateholders will be deemed to be the owners of the Supplemental Interest Reserve Fund and all amounts deposited into the Supplemental Interest Reserve Fund (other than the 79 initial $10,000 deposit) shall be treated as amounts distributed by the REMIC II with respect to the Class B-IO Distribution Amount and Class II-B-IO Distribution Amount. Amounts held in the Supplemental Interest Reserve Fund and not distributable to the Adjustable Rate Certificateholders on any Distribution Date will be invested by the Trustee in investments designated by the Class B-IO Certificateholders having maturities on or prior to the next succeeding Distribution Date on which such amounts will be distributable to the Adjustable Rate Certificateholders. Upon the termination of the Trust, or the payment in full of the Adjustable Rate Certificates, all amounts remaining on deposit in the Supplemental Interest Reserve Fund will be released from the lien of the Trust and distributed to the Class B-IO Certificateholders or their designees, pro rata. The Supplemental Interest Reserve Fund will be part of the Trust but not part of any REMIC created hereunder and any payments to the Adjustable Rate Certificates of WAC Excess will not be payments with respect to a "regular interest" in a REMIC within the meaning of Code Section 860G(a)(1). (b) The Trustee shall treat the Supplemental Interest Reserve Fund as an outside reserve fund within the meaning of Treasury Regulation Section 1.860G-2(h) that is owned by the Class B-IO Certificateholders and that is not an asset of any REMIC. The Trustee shall treat the rights of the Adjustable Rate Certificateholders to receive payments from the Supplemental Interest Reserve Fund as rights in an interest rate cap contract written by the Class B-IO Certificateholders in favor of the Adjustable Rate Certificateholders. Thus, each Adjustable Rate Certificate shall be treated as representing not only ownership of a regular interest in REMIC II, but also ownership of an interest in an interest rate cap contract. (c) Notwithstanding the priority and sources of payments set forth in Section 5.04(a) hereof or otherwise, the Trustee shall account for all distributions on the Certificates as set forth in this section. In no event shall any payments provided for in this section be treated as payments with respect to a "regular interest" in a REMIC within the meaning of Code Section 860G(a)(1) and shall be treated as an asset held separate and apart from any REMIC created under this Agreement in accordance with Treasury regulation section 1.860G-2(i). 80 ARTICLE VI.

The Class I-B-IO Certificates will be entitled to receive certain distributions as provided for in Section 5.04.

(17) Initially $4,103,414 and thereafter the aggregate Stated Principal Balance of the Group II Mortgage Loans as of the last day of the related Due Period. The Class II-B-IO Certificates will be entitled to receive certain distributions as provided for in Section 5.04. Other than for federal income tax purposes, the Class II-B-IO Distribution Amount may be deemed to be interest on the notional principal balance of the Class II-B-IO Certificates. 82 The Certificates shall be executed by manual or facsimile signature on behalf of the Trustee 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 Trustee shall bind the Trustee, 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 authentication of the Trustee by manual signature, and such authentication upon any Certificate shall be conclusive evidence, and the only evidence, that such Certificate has been duly authenticated and delivered hereunder. All Certificates shall be dated the date of their authentication. On the Closing Date, the Trustee 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 Trustee on a continuous basis, an adequate inventory of Certificates to facilitate transfers. Section 6.02. Certificate Register; Registration of Transfer and Exchange of Certificates. (a) The Trustee shall maintain, or cause to be maintained in accordance with the provisions of Section 6.09 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 Trustee 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 Trustee 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 Trustee. Whenever any Certificates are so surrendered for exchange, the Trustee 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 Trustee 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 Trustee in accordance with the Trustee's customary procedures. (b) No Transfer of a Class I-B Certificate or a Class B-IO 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 Trustee and the Securities Administrator in writing the facts surrounding the Transfer in substantially the forms set forth in Exhibit E (the "Transferor Certificate") and (x) deliver a letter in substantially the form of either Exhibit F (the "Investment Letter") or Exhibit G (the "Rule 144A Letter") or (y) there shall be delivered to the Trustee and the Securities 83 Administrator an Opinion of Counsel addressed to the Trustee and 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, any Servicer, the Master Servicer, the Securities Administrator or the Trustee. The Depositor shall provide to any Holder of a Class I-B Certificates or a Class B-IO 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 Trustee, 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 Class I-B Certicates or a Class B-IO 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 the Trustee, the Master Servicer and the Securities Administrator shall have received either (i) a representation from the transferee of such Certificate acceptable to and in form and substance satisfactory to the Trustee 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 ("Plan"), or a Person, directly or indirectly, acting on behalf of any such Plan, or (ii) in the case of any such ERISA Restricted Certificate presented for registration in the name of a Plan, or a trustee of any Plan or any other person, directly or indirectly, acting on behalf of any such Plan, a representation satisfactory to the Trustee and the Securities Administrator to the effect that neither the purchase or holding of such ERISA Restricted Certificate nor the servicing, management and operation of the Trust Fund will result in any prohibited transactions under ERISA or Section 4975 of the Code which will not be covered under Prohibited Transactions Class Exemption ("PTCE") 84-14, PTCE 90-1, PTCE 91-38, PTCE 95-60, PTCE 96-23 or some other applicable exemption and will not subject the Trustee, the Securities Administrator, any Servicer, the Master Servicer or the Depositor to any fiduciary duties under ERISA in addition to those expressly undertaken in this Agreement, which in the case of a Book-Entry Certificate shall be deemed to have been represented by the Transferee. Notwithstanding anything else to the contrary herein, any purported transfer of an ERISA Restricted Certificate to or on behalf of any Plan without satisfying the above conditions shall be void and of no effect. 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 6.02(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 be entitled, but not obligated, to recover from any Holder of any ERISA Restricted Certificate that was in fact a Plan or a Person, directly or indirectly, acting on behalf of any Plan at the time it became a Holder or, at such subsequent time as it became a Plan or Person acting on behalf of 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 a Plan or Person acting on behalf of a Plan. 84 (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 which shall always be issued as a physical certificate and not as a Book-Entry Certificate shall be a Permitted Transferee and shall promptly notify the Trustee 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 Trustee shall not register the Transfer of any Residual Certificate unless, in addition to the certificates required to be delivered to the Trustee under subparagraph (b) above, the Trustee 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 D. (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 6.02(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 6.02(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 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 6.02(b) and this Section 6.02(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 and Transferor Certificate. The Trustee 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 Trustee 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 Trustee, 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 6.02(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 Trustee of an Opinion of Counsel addressed to the 85 Trustee, which Opinion of Counsel shall not be an expense of the Trustee, the Securities Administrator, the Seller, any Servicer or the Master Servicer to the effect that the elimination of such restrictions will not cause the 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 furnished to the Trustee, 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 6.02 shall not be an expense of the Trust Fund, the Trustee, the Depositor, the Seller, the Securities Administrator, the Master Servicer or any Servicer. Section 6.03. Mutilated, Destroyed, Lost or Stolen Certificates. If (a) any mutilated Certificate is surrendered to the Trustee, or the Trustee 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 Master Servicer, the Securities Administrator and the Trustee such security or indemnity as may be required by them to save each of them harmless, then, in the absence of notice to the Trustee that such Certificate has been acquired by a bona fide purchaser, the Trustee 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 6.03, the Trustee 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 Trustee) connected therewith. Any replacement Certificate issued pursuant to this Section 6.03 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 Trustee under the terms of this Section 6.03 shall be canceled and destroyed by the Trustee in accordance with its standard procedures without liability on its part. Section 6.04. 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 6.05. Access to List of Certificateholders' Names and Addresses. If three or more Certificateholders (a) request such information in writing from the Trustee, (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 Trustee, then the Trustee 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 Trustee, if any. The Depositor and every Certificateholder, by receiving and holding a 86 Certificate, agree that the Trustee 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 6.06. Book-Entry Certificates. The Regular Certificates (other than the Class I-B Certificates and the Class B-IO 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 or its agent 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 6.08. Unless and until definitive, fully registered Certificates ("Definitive Certificates") have been issued to the Certificate Owners of such Certificates pursuant to Section 6.08: (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 Trustee 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 6.08, 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 Trustee 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 6.07. 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 87 Certificates shall have been issued to the related Certificate Owners, the Trustee shall give all such notices and communications to the Depository. Section 6.08. Definitive Certificates. If, after Book-Entry Certificates have been issued with respect to any Certificates, (a) the Depositor or the Depository advises the Trustee 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 or (b) 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 Trustee 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 Trustee 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 Trustee with an adequate inventory of certificates to facilitate the issuance and transfer of Definitive Certificates. Upon surrender to the Trustee of any such Certificates by the Depository, accompanied by registration instructions from the Depository for registration, the Trustee shall authenticate and deliver such Definitive Certificates. Neither the Depositor nor the Trustee 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 Trustee, to the extent applicable with respect to such Definitive Certificates and the Trustee shall recognize the Holders of such Definitive Certificates as Certificateholders hereunder. Section 6.09. Maintenance of Office or Agency. The Trustee will maintain or cause to be maintained at its expense an office or offices or agency or agencies in New York City or at the Corporate Trust Office (if not in New York City) where Certificates may be surrendered for registration of transfer or exchange. The Trustee initially designates its Corporate Trust Office in Dallas, Texas, as the office for such purposes. The Trustee will give prompt written notice to the Certificateholders of any change in such location of any such office or agency. 88 ARTICLE VII.

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, (i) in the case of the Master Servicer, 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 92 each Rating Agency) and (ii) in the case of the EMC Servicer, the Master Servicer may, by notice in writing to the EMC Servicer (with a copy to each Rating Agency), terminate all of the rights and obligations of the Master Servicer or the EMC Servicer, as applicable, 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 hereunder, whether with respect to the Mortgage Loans or otherwise, shall pass to and be vested in the EMC Servicer, as successor Master Servicer or, if the EMC Servicer is unable or unwilling to act as such successor Master Servicer, the Trustee, or any successor appointed pursuant to Section 8.02 (a "Successor Master Servicer"). Such Successor Master Servicer shall thereupon make any Advance described in Section 5.01 hereof and payments of Compensating Interest pursuant to Section 5.02 hereof, subject, in the case of the Trustee, to Section 8.02. The Trustee is hereby authorized and empowered to execute and deliver, on behalf of the terminated Master Servicer, as attorney-in-fact or otherwise, any and all documents and other instruments, and to do or accomplish all other acts or things necessary or appropriate to effect the purposes of such notice of termination, whether to complete the transfer and endorsement 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 IX. The Master Servicer and the EMC Servicer each agree to cooperate with the Trustee, and, in the case of the EMC Servicer, the Master Servicer, in effecting the termination of the Master Servicer's or the EMC Servicer's responsibilities and rights hereunder (including Exhibit K), including, without limitation, the transfer to the applicable Successor Master Servicer or the Master Servicer, as applicable, of all cash amounts which shall at the time be credited to the Master Servicer Collection Account or the Protected Account maintained pursuant to Section 1.05 of Exhibit K, as applicable, 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 with respect to the Master Servicer actually known to a Responsible Officer of the Trustee. Notwithstanding any termination of the activities of the Master Servicer or the EMC Servicer hereunder, the Master Servicer or the EMC 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 or EMC Servicer's rights and obligations as Master Servicer or Servicer hereunder, as applicable, and received after such notice, that portion thereof to which the Master Servicer or the EMC Service would have been entitled pursuant to Sections 4.03 and 4.05 or Exhibit K, as applicable, and to receive any other amounts payable to the Master Servicer or the EMC Servicer hereunder the entitlement to which arose prior to the termination of its activities hereunder. Section 8.02. Trustee to Act; Appointment of Successor. On and after the time the Master Servicer receives a notice of termination pursuant to Section 8.01 hereof (unless, the EMC Servicer becomes Successor Master Servicer as specified in Section 8.01) 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 and applicable law including, if applicable, the obligation to make Advances pursuant to Section 5.01 hereof, and payments of Compensating Interest pursuant to Section 5.02 hereof, except as otherwise provided herein. Effective on the date of such notice of termination, as compensation therefor, the Trustee shall be entitled to all fees, costs and expenses relating to the Mortgage Loans 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 losses pursuant to Section 3.09 or Section 4.02(c) or as a result of any acts or omissions of the Master Servicer, (ii) obligated to make 93 Advances if it is prohibited from doing so under applicable law, (iii) obligated to effectuate any repurchases or substitutions of Mortgage Loans hereunder, including pursuant to Section 2.02 or 2.03 hereof, (iv) responsible for expenses of the Master Servicer pursuant to Section 2.03 or (v) deemed to have made any representations and warranties hereunder, including pursuant to Section 2.03. 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 Section 5.01 hereof, 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 any Servicing Agreement with respect to which 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 8.01 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 8.02, 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 3.04 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 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 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 and the Successor Master Servicer 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 and the Successor Master Servicer pursuant to Section 9.05. Any successor to the Master Servicer as successor servicer under any Servicing 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 7.06. 94 Section 8.03. 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 with respect to the Master Servicer, 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. 95 ARTICLE IX. CONCERNING THE TRUSTEE AND THE SECURITIES ADMINISTRATOR Section 9.01. Duties of Trustee and Securities Administrator. (a) The Trustee, prior to the occurrence of an Event of Default and after the curing or waiver of all Events of Default which may have occurred, and the Securities Administrator each undertake to perform such duties and only such duties as are specifically set forth in this Agreement as duties of the Trustee and the Securities Administrator, respectively.

(d) No provision of this Agreement shall be construed to relieve the Trustee or the Securities Administrator from liability for its own negligent action, its own negligent failure to act or its own willful misconduct; provided, however, that: (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 therein, upon any certificates or opinions furnished to the Trustee or the Securities Administrator, respectively, and conforming to the requirements of this Agreement; (ii) Neither the Trustee nor the Securities Administrator shall be liable for an error of judgment made in good faith by a Responsible Officer or Responsible Officers of the Trustee or an officer or officers of the Securities Administrator, respectively, unless it shall be proved that the Trustee or the Securities Administrator, respectively, was negligent in ascertaining the pertinent facts; 96 (iii) Neither the Trustee nor the Securities Administrator shall be liable with respect to any action taken, suffered or omitted to be taken by it in good faith in accordance with the directions of the Holders of Certificates evidencing not less than 25% of the aggregate Voting Rights of the Certificates, if such action or non-action relates to the time, method and place of conducting any proceeding for any remedy available to the Trustee or the Securities Administrator, respectively, or exercising any trust or other power conferred upon the Trustee or the Securities Administrator, respectively, under this Agreement; (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 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, any Servicer, the Seller, the Depositor, the Custodian or the Trustee shall be responsible for the acts or omissions of the others, 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 hereunder or under the applicable Servicing Agreements. (e) All funds received by the Trustee and required to be deposited in the Distribution Account pursuant to this Agreement will be promptly so deposited by the Trustee. Section 9.02. Certain Matters Affecting the Trustee and the Securities Administrator. (a) Except as otherwise provided in Section 9.01: (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 or the Master Servicer or any 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; 97 (ii) The Trustee and the Securities Administrator may consult with counsel or accountants and any advice of such counsel or accountants 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 agent other than the Custodian to perform its custodial functions with respect to the Mortgage Files or 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 or delayed. 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 a custodian 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; 98 (vii) Should the Trustee or the Securities Administrator deem the nature of any action required on its part, other than a payment or transfer under Section 4.02 hereof, 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 gross 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 9.07; 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 9.03. Trustee and Securities Administrator Not Liable for Certificates or Mortgage Loans The recitals contained herein and in the Certificates (other than the signature and authentication 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 representations as to the validity or sufficiency of the Certificates (other than the signature and authentication of the Trustee on the Certificates) or with respect to any Mortgage Loan except as expressly provided in Sections 2.02 and 2.06 hereof; provided, however, that the foregoing shall not relieve the Custodian of the obligation to review the Mortgage Files pursuant to Sections 2.02 and 2.05 and the Custodial Agreement. The Trustee's signature and authentication (or authentication by 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 the provisions of 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 9.04. 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 99 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 9.05. Trustee's and Securities Administrator's Fees and Expenses. The Trustee and the Securities Administrator shall be entitled to the Trustee Fee and the Securities Administrator Fee, respectively, which shall be paid by the Master Servicer out of funds received by it hereunder in respect of the Master Servicing Fee. In addition, the Trustee and the Securities Administrator shall be indemnified and held harmless by the Trust Fund (and accordingly will be entitled to recover from the Master Servicer Collection Account pursuant to Section 4.03(b) and from comparable funds in a comparable order provided to the Trustee and held in the Distribution Account) for all liabilities, losses, costs, reasonable out-of-pocket expenses, disbursements and advances and the expenses of the Trustee and the Securities Administrator, respectively, in connection with the performance of its duties and obligations and the exercise of its rights under this Agreement, (including exercise of such party's rights under the Assumption Agreements and the Servicing Agreements), the Custodial Agreement, the Certificates, the Mortgage Loans, 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 in the administration of the trusts hereunder or the Securities Administrator, respectively, (including the reasonable compensation, expenses and disbursements of its counsel) except any such liability, loss, cost, expense, disbursement or advance as may arise from its negligence, bad faith or intentional misconduct. The Trust Fund further agrees to indemnify and hold harmless the Trustee for and against any loss, liability or expense arising out of, or in connection with, the provisions set forth in the final paragraph of Section 2.01 hereof, including without limitation, all costs, liabilities and expenses (including reasonable legal fees and expenses) of investigation and defending itself against any claim, action or proceeding, pending or threatened, relating to the provisions of such paragraph. If such funds are insufficient therefor, any such insufficiency shall be recoverable from the Depositor. 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. The indemnification set forth herein shall survive the resignation or removal of the Trustee or the Securities Administrator and the termination of this Agreement. Section 9.06. 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 S&P, "Baa2" or higher by Moody's and "BBB/F2" or higher by Fitch, 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 9.10, 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 9.06 the combined capital and surplus of such entity 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 9.06, the Trustee or the Securities Administrator shall resign immediately in the manner and with the effect specified in Section 9.08. 100 In addition, the Securities Administrator (i) may not be an Originator, Master Servicer, Servicer, the Depositor or an affiliate of the Depositor unless the Securities Administrator is in an institutional trust department of the Securities Administrator, (ii) must be authorized to exercise corporate trust powers under the laws of its jurisdiction of organization, and (iii) must be rated at least "A/F1" by Fitch, if Fitch is a Rating Agency, or the equivalent rating by S&P or Moody's. The Trustee shall notify the Rating Agencies of any change of Securities Administrator. Section 9.07. Insurance. 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 9.07 shall be furnished to any Certificateholder upon reasonable written request. Section 9.08. Resignation and Removal of Trustee and Securities Administrator. The Trustee and the Securities Administrator may at any time resign 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 9.06 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 Servicers 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, the 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 101 successor trustee or successor securities administrator to 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. In the event that the fee payable to a successor Trustee exceeds the Trustee Fee, any such excess shall be an obligation of the Trust. 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 9.08 shall become effective upon acceptance of appointment by the successor trustee or securities administrator as provided in Section 9.09 hereof. Section 9.09. Successor Trustee or Securities Administrator. Any successor trustee or securities administrator appointed as provided in Section 9.08 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 9.09 unless at the time of such acceptance such successor trustee or securities administrator shall be eligible under the provisions of Section 9.07 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 9.09, 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 9.10. 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 entity shall be eligible under the provisions of Section 9.06 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 9.11. 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 102 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 9.11, 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 9.06 and no notice to Certificateholders of the appointment of any co-trustee or separate trustee shall be required under Section 9.09. 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 as 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 IX. 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. 103 Section 9.12. Tax Matters. It is intended that each of REMIC I and REMIC II 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 (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 Forms 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) or to the IRS, and the Trustee shall forward that information to the requesting party in accordance with Treasury Regulation ss. 1.860E-2(a)(5); (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 second to last paragraph of this Section 9.12, 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 9.12 requiring a signature thereon by the Trustee; (j) the Securities Administrator shall maintain 104 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; and (k) 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, which indemnification shall survive the resignation or removal of the Trustee, the Master Servicer, the EMC Servicer or the Securities Administrator and the termination of this Agreement. In the event that any tax is imposed on "prohibited transactions" of either 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 either 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, REMIC II or the Trust Fund, 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 the Class B-IO Certificateholders (pro rata based on the amounts to be distributed), and second with amounts otherwise to be distributed to all other Certificateholders in the following order of priority: first, to the Class B Certificates of both Groups (pro rata based on amounts to be distributed), second, to the Class M Certificates of both Groups (pro rata based on amounts to be distributed) and third, to the Class A Certificates of both Groups (pro rata based on 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 Trustee 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. Following written notification to the Securities Administrator by the Trustee of any amount payable out of distributions to the 105 Certificateholders pursuant to the preceding two sentences, 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 9.12, 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 9.12, 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. 106 ARTICLE X. TERMINATION Section 10.01. Termination upon Liquidation or Repurchase of the Mortgage Loans. Subject to Section 10.03, the obligations and responsibilities of the Depositor, the Master Servicer, the EMC Servicer, the Securities Administrator, the Seller and the Trustee created hereby with respect to a Group shall terminate upon the earlier of (a) the purchase by the Depositor of all of the Mortgage Loans (and REO Properties) remaining in the Trust Fund with respect to the related Group at the price equal to the sum of (i) 100% of the Stated Principal Balance of each Mortgage Loan (other than in respect of REO Property in such Group), (ii) accrued interest thereon at the applicable Mortgage Rate, (iii) the appraised value of any REO Property in such Group (up to the Stated Principal Balance of the related Mortgage Loan), such appraisal to be conducted by an appraiser mutually agreed upon by the EMC Servicer and the Securities Administrator and (iv) unreimbursed out-of pocket costs of the related Servicer or Master Servicer, including unreimbursed servicing advances and the principal portion of any unreimbursed Advances, made on the related Mortgage Loans prior to the exercise of such repurchase right, (v) any unreimbursed costs and expenses of the Trustee and the Securities Administrator payable pursuant to Section 9.05 and (vi) any unreimbursed costs and expenses of the Custodian payable pursuant to the Custodial Agreement and (b) the later of (i) the maturity or other liquidation (or any Advance with respect thereto) of the last Mortgage Loan remaining in the Trust Fund and the disposition of all REO Property, and (ii) the distribution to Certificateholders of all amounts required to be distributed to them pursuant to this Agreement, as applicable. In no event shall the trusts created hereby continue beyond the earlier of (i) the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James's, living on the date hereof and (ii) the Latest Possible Maturity Date. The right to repurchase all Mortgage Loans and REO Properties in a Group pursuant to clause (a) above shall be conditioned upon the Stated Principal Balance of all of the Mortgage Loans in such Group, at the time of any such repurchase, aggregating, in the case of Group I, ten percent or less and, in the case of Group II, twenty percent or less, of the aggregate Cut-off Date Principal Balance of all of the Mortgage Loans in the related Group. Section 10.02. Final Distribution on the Certificates. If on any Determination Date, (i) the Master Servicer determines that there are no Outstanding Mortgage Loans and no other funds or assets in a Group other than the funds in the Master Servicer Collection Account, the Master Servicer shall direct the Securities Administrator to send a final distribution notice promptly to each related Certificateholder or (ii) the Securities Administrator determines that a Class of Certificates shall be retired after a final distribution on such Class, the Securities Administrator shall notify the Certificateholders within five (5) Business Days after such Determination Date that the final distribution in retirement of such Class of Certificates is scheduled to be made on the immediately following Distribution Date. Any final distribution made pursuant to the immediately preceding sentence will be made only upon presentation and surrender of the related Certificates at the Corporate Trust Office of the Trustee. If the Depositor elects to terminate a Group pursuant to Section 10.01, on or before the Distribution Date occurring in the month preceding the month in which notice is to be mailed to the Certificateholders, the Depositor shall notify the Securities Administrator, the Custodian, the Trustee, the Securities Administrator and the Master Servicer of the date that the Depositor intends to terminate the Group and the Depositor shall provide the EMC Servicer, the Securities Administrator, the Custodian, the Master Servicer and the Trustee with the applicable repurchase price of the Mortgage Loans and REO Properties of such Group serviced and administered by the 107 Master Servicer. The EMC Servicer shall remit the Mortgage Loan Repurchase Price to the Trustee for deposit in the Distribution Account on the Business Day immediately preceding the Distribution Date on which such Optional Termination by the EMC Servicer will be effected. Provided that timely notice has been received, the Securities Administrator shall give notice of any termination of a Group, specifying the Distribution Date on which Certificateholders may surrender their Certificates for payment of the final distribution and cancellation. To the extent reasonably practical, such notice shall be given by letter mailed not earlier than the 1st day and no later than the 15th day of the month of such final distribution and 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 Trustee 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 shall promptly release to the EMC Servicer or its designee the Mortgage Files for the Mortgage Loans, and any documents necessary to transfer any REO Property. Upon presentation and surrender of the Certificates, the Trustee shall cause to be distributed to Certificateholders of each Class, based on the applicable Remittance Report for such Distribution Date, the amounts allocable to such Certificates held in the Distribution Account in the order and priority set forth in Section 5.04 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 10.03. Additional Termination Requirements. (a) Upon exercise by the Depositor of its purchase option with respect to both Groups as provided in Section 10.01, 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, at the expense of the EMC Servicer, to the effect that the failure of the Trust Fund to comply with the requirements of this Section 10.03 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: 108 (1) The Depositor 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 each of REMIC I and REMIC II's Tax Return pursuant to Treasury Regulation Section 1.860F-1. The Depositor 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 obtained at the expense of the Depositor; (2) During such 90-day liquidation period, and at or prior to the time of making the final payment on the Certificates, the EMC Servicer, acting as agent of the Trustee, shall sell all of the assets of REMIC I and REMIC II for cash; and (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 and REMIC II shall terminate at that time. (b) By their acceptance of the Certificates, the Holders thereof hereby authorize the Depositor to specify the 90-day liquidation period for REMIC I and REMIC II, which authorization shall be binding upon all successor Certificateholders. (c) 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 Depositor, and the receipt of the Opinion of Counsel referred to in Section 10.03(a)(1) and to take such other action in connection therewith as may be reasonably requested by the Depositor. 109 ARTICLE XI. MISCELLANEOUS PROVISIONS Section 11.01. 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, or the Protected Account maintained by the EMC Servicer is maintained, to conform the terms hereof to the disclosure in the Prospectus Supplement 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 either REMIC I or REMIC II pursuant to the Code that would be a claim against either 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 amendment but in any case shall not be an expense of the Trustee or the Securities Administrator, 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 either REMIC I or REMIC II's REMIC elections to fail to qualify 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 or REMIC II or the Certificateholders or cause REMIC I or REMIC II's REMIC elections to fail to qualify 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, addressed to and satisfactory to the Trustee that (i) such 110 amendment is permitted and is not prohibited by this Agreement and 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 11.02. 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 11.03. 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 LAW WHICH THE PARTIES HERETO EXPRESSLY RELY UPON IN THE CHOICE OF SUCH LAW AS THE GOVERNING LAW HEREUNDER). Section 11.04. 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 this Agreement is held 111 or deemed to create a security interest in such assets, then (i) this Agreement shall be deemed to be a security agreement within the meaning of the Uniform Commercial Code of the State of New York, (ii) each conveyance provided for in this Agreement 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, (iii) the possession by the Trustee or the Custodian of the Mortgage Notes and such other items of property as may be perfected by possession pursuant to Section 9-313 (or comparable provision) of the applicable Uniform Commercial Code for purposes of effecting the security interest pursuant to such section of the applicable Uniform Commercial Code and other applicable law. Any assignment of the Seller and the Depositor shall also be deemed to be an assignment of any security interest created hereby. Each of the Seller and 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.

Notwithstanding anything to the contrary contained herein, except as provided pursuant to Section 7.02, this Agreement may not be assigned by the Master Servicer, the EMC Servicer, the Seller or the Depositor. Section 11.08. 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 113 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.

(a) 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 11.09 shall be borne by the party requesting such inspection, subject to any right to reimbursement of such party hereunder (in the case of the Trustee, pursuant to Section 4.05(a)(xii) hereof); all other such expenses shall be borne by the Master Servicer. (b) The Trustee and the Securities Administrator shall each provide access to the records and documentation in its possession 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 its respective office; provided, however, that, unless otherwise required by law, neither the Trustee 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 and the Securities Administrator shall each 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 its actual costs. Section 11.10. Certificates Nonassessable and Fully Paid.

Capitalized terms used, but not defined herein or in Exhibit 1 hereto, shall have the meanings ascribed to such terms in the Agreement. The Transferee has authorized the undersigned to make this affidavit on behalf of the Transferee. 2. The Transferee is, as of the date hereof, and will be, as of the date of the Transfer, a Permitted Transferee. The Transferee is acquiring its Ownership Interest in the Certificate for its own account. 3. The Transferee has been advised of, and understands that (i) a tax will be imposed on Transfers of the Certificate to Persons that are not Permitted Transferees; (ii) such tax will be imposed on the transferor, or, if such Transfer is through an agent (which includes a broker, nominee or middleman) for a Person that is not a Permitted Transferee, on the agent; and (iii) the Person otherwise liable for the tax shall be relieved of liability for the tax if the subsequent Transferee furnished to such Person an affidavit that such subsequent Transferee is a Permitted Transferee and, at the time of Transfer, such Person does not have actual knowledge that the affidavit is false. 4. The Transferee has been advised of and understands that a tax will be imposed on a "pass-through entity" holding the Certificate if at any time during the taxable year of the pass-through entity a Person that is not a Permitted Transferee is the record holder of an interest in such entity. The Transferee understands that such tax will not be imposed for any period with respect to which the record holder furnishes to the pass-through entity an affidavit that such record holder is a Permitted Transferee and the pass-through entity does not have actual knowledge that such affidavit is false. (For this purpose, a "pass-through entity" includes a regulated investment company, a real estate investment trust or common trust fund, a partnership, trust or estate, and certain cooperatives and, except as may be provided in Treasury Regulations, persons holding interests in pass-through entities as a nominee for another Person.) 5. The Transferee has reviewed the provisions of Section 6.02(c) of the Agreement (attached hereto as Exhibit 2 and incorporated herein by reference) and understands the legal consequences of the acquisition of an Ownership Interest in the Certificate including, without limitation, the restrictions on subsequent Transfers and the provisions regarding voiding the D-1 Transfer and mandatory sales. The Transferee expressly agrees to be bound by and to abide by the provisions of Section 6.02(c) of the Agreement and the restrictions noted on the face of the Certificate. The Transferee understands and agrees that any breach of any of the representations included herein shall render the Transfer to the Transferee contemplated hereby null and void. 6. The Transferee agrees to require a Transfer Affidavit from any Person to whom the Transferee attempts to Transfer its Ownership Interest in the Certificate, and in connection with any Transfer by a Person for whom the Transferee is acting as nominee, trustee or agent, and the Transferee will not Transfer its Ownership Interest or cause any Ownership Interest to be Transferred to any Person that the Transferee knows is not a Permitted Transferee. In connection with any such Transfer by the Transferee, the Transferee agrees to deliver to the Trustee a certificate substantially in the form set forth as Exhibit E to the Agreement (a "Transferor Certificate") to the effect that such Transferee has no actual knowledge that the Person to which the Transfer is to be made is not a Permitted Transferee. 7. The Transferee does not have the intention to impede the assessment or collection of any tax legally required to be paid with respect to the Class R Certificates. 8. The Transferee's taxpayer identification number is _____. 9. The Transferee is a U.S. Person as defined in Code Section 7701(a)(30). 10. The Transferee is aware that the Class R Certificate may be "noneconomic residual interests" within the meaning of Treasury regulations promulgated pursuant to the Code and that the transferor of a noneconomic residual interest will remain liable for any taxes due with respect to the income on such residual interest, unless no significant purpose of the transfer was to impede the assessment or collection of tax. In addition, as the holder of a noneconomic residual interest, the Transferee may incur tax liabilities in excess of any cash flows generated by the interest and the Transferee hereby represents that it intends to pay taxes associated with holding the residual interest as they become due. 11.

(ii) No Ownership Interest in a Residual Certificate may be registered on the Closing Date or thereafter transferred, and the Trustee shall not register the Transfer of any Residual Certificate, unless, in addition to the certificates required to be delivered to the Trustee under subparagraph (b) above, the Trustee 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 D. (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 6.02(c) shall be absolutely null and void and shall vest no rights in the purported Transferee.

The Trustee 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 Trustee D-5 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 Trustee, 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 6.02(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 Trustee of an Opinion of Counsel addressed to the Trustee, which Opinion of Counsel shall not be an expense of the Trustee, the Seller, or the Master Servicer to the effect that the elimination of such restrictions will not cause the 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 furnished to the Trustee, 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.

For and on behalf of the Certificateholders, the EMC Servicer 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 Mortgaged Properties are located. In connection with such servicing and administration, the EMC Servicer shall have full power and authority, acting alone and/or through subservicers as provided in Section 1.02 of this Exhibit K, 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 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 1.12(a) of this Exhibit K, to effectuate foreclosure or other conversion of the ownership of the Mortgaged Property securing any EMC Mortgage Loan; provided that the EMC Servicer 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 the Agreement. The EMC Servicer shall represent and protect the interest of the Trust Fund in the same manner as it currently protects its own interest in EMC Mortgage Loans in its own portfolio in any claim, proceeding or litigation regarding an EMC Mortgage Loan and shall not make or permit any modification, waiver or amendment of any term of any EMC Mortgage Loan which would cause the Trust Fund to fail to qualify as a REMIC or result in the imposition of any tax under the REMIC Provisions, but in any case not in any manner that is a lesser standard than that provided in the first sentence of this Section 1.01. Without limiting the generality of the foregoing, the EMC Servicer, 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 EMC Servicer 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 Mortgaged Properties held for the benefit of the Certificateholders.

In accordance with the standards of the preceding paragraph, the EMC Servicer 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, which advances shall be reimbursable in the first instance from related collections from the Mortgagors pursuant to Section 1.06 of this Exhibit K, and further as provided in Section 1.08 of this Exhibit K.

The EMC Servicer shall deliver a list of Servicing Officers to the Master Servicer and the Trustee by the Closing Date. Section 7.02. Subservicing; Enforcement of the Obligations of EMC Servicer. (a) The EMC Servicer may arrange for the subservicing of any EMC Mortgage Loan by a subservicer (each, a "Subservicer") pursuant to a subservicing agreement (each, a "Subservicing Agreement"); provided that such subservicing arrangement and the terms of the related subservicing agreement must provide for the servicing of such EMC Mortgage Loans in a manner consistent with the servicing arrangements contemplated hereunder. Notwithstanding the provisions of any subservicing agreement, any of the provisions herein relating to agreements or arrangements between the EMC Servicer or a subservicer or reference to actions taken through the EMC Servicer or otherwise, the EMC Servicer shall remain obligated and liable to the Depositor, the Trust, the Trustee and the Certificateholders for the servicing and administration of the EMC Mortgage Loans in accordance with the provisions of the Agreement without diminution of such obligation or liability by virtue of such subservicing agreements or arrangements or by virtue of indemnification from the subservicer and to the same extent and under the same terms and conditions as if the EMC Servicer alone were servicing and administering the EMC Mortgage Loans, and neither the Master Servicer nor the Trustee or any other party 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 or any other party to pay such subservicer's fees and expenses. For purposes of remittance to the Master Servicer pursuant to the Agreement, the EMC Servicer shall be deemed to have received a payment on an EMC Mortgage Loan when a subservicer has received such payment. The EMC Servicer shall be entitled to enter into an agreement with a subservicer to provide for the delivery of reports and for indemnification of the EMC Servicer by the subservicer and nothing contained in the Agreement shall be deemed to limit or modify such indemnification. Every subservicing agreement entered into by the EMC Servicer shall contain a provision giving the EMC Servicer the option to terminate such agreement and at the EMC Servicer's option, service the related EMC Mortgage Loans itself pursuant to the Agreement or arrange for any servicing responsibilities to be performed pursuant to the applicable subservicing agreement by a successor subservicer. Any costs and expenses relating to such termination and K-2 transfer of servicing shall be the sole expense of the EMC Servicer, without any right to reimbursement from the Protected Account, the Master Servicer Collection Account or the Distribution Account. All actions of each subservicer performed pursuant to the related subservicing agreement shall be performed as an agent of the EMC Servicer with the same force and effect as if performed directly by the EMC Servicer. (b) For purposes of the Agreement, the EMC Servicer shall be deemed to have received any collections, recoveries or payments with respect to the EMC Mortgage Loans that are received by a subservicer regardless of whether such payments are remitted by the subservicer to the EMC Servicer. Section 7.03. Rights of the Depositor, the Master Servicer and the Trustee in Respect of the EMC Servicer. Neither the Trustee nor the Depositor nor the Master Servicer shall have any responsibility or liability for any action or failure to act by the EMC Servicer, and neither the Depositor nor the Trustee is obligated to supervise the performance of the EMC Servicer hereunder or otherwise. Section 7.04. Reserved. Section 7.05. Collection of EMC Mortgage Loan Payments; Protected Account. (a) The EMC Servicer 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 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 the Agreement and the terms and provisions of any related Required Insurance Policy. Consistent with the foregoing, the EMC Servicer may in its discretion (i) waive any late payment charge or penalty interest in connection with the prepayment of an EMC Mortgage Loan and (ii) extend the due dates for payments due on a Mortgage Note for a period not greater than 125 days. In the event of any such arrangement, the EMC Servicer shall make Advances on the related EMC Mortgage Loan (except with respect to principal on Simple Interest Loans) 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 2.01 of this Exhibit K. The EMC Servicer 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 EMC Servicer delivers to the Master Servicer and the Trustee a certification, 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 REMIC formed under the Agreement, the EMC Servicer 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 6.0% and (B) amend any Mortgage Note to extend to the maturity thereof. K-3 (b) The EMC Servicer shall establish and maintain an Eligible Account with a depositary institution in the name of the EMC Servicer for the benefit of the Trustee on behalf of the Certificateholders and designated "JPMorgan Chase Bank, N.A., in trust for registered holders of Bear Stearns Asset Backed Securities, Inc., Asset-Backed Certificates Series 2005-SD1" (the "Protected Account"). The Protected Account shall not be a part of the Trust Fund. The EMC Servicer 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 EMC Mortgage Loans subsequent to the Cut-off Date (other than in respect of principal and interest due on the EMC Mortgage Loans, other than Simple Interest 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 (other than, in the case of a Simple Interest Loan, interest paid in excess of 30 days interest) on the EMC Mortgage Loans net of the related Servicing Fee permitted under Section 1.16 of this Exhibit K; (iii) all Liquidation Proceeds, Insurance Proceeds and any Subsequent Recoveries, other than proceeds to be applied to the restoration or repair of the Mortgaged Property or released to the Mortgagor in accordance with the EMC Servicer's normal servicing procedures; (iv) [Reserved]; (v) any amount required to be deposited by the EMC Servicer pursuant to Section 1.05(d) of this Exhibit K in connection with any losses on Permitted Investments; (vi) any amounts required to be deposited by the EMC Servicer pursuant to Section 1.10 of this Exhibit K; and (vii) any other amounts required to be deposited hereunder. The foregoing requirements for remittance by the EMC Servicer 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 Prepayment Charges, late payment charges or assumption fees, if collected, need not be remitted by the EMC Servicer. In the event that the EMC Servicer shall remit any amount not required to be remitted and not otherwise subject to withdrawal pursuant to Section 1.08 of this Exhibit K, 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 EMC Servicer shall maintain adequate records with respect to all withdrawals made pursuant to K-4 this Section. All funds deposited in the Protected Account shall be held in trust for the Certificateholders until withdrawn in accordance with Section 1.08 of this Exhibit K. (c) [Reserved.] (d) The institution that maintains the Protected Account shall invest the funds in the Protected Account, in the manner directed by the EMC Servicer, in Permitted Investments which shall mature not later than the second Business Day next preceding the related Servicer Remittance Date (except that if such Permitted Investment is an obligation of the institution that maintains such Protected Account, then such Permitted Investment shall mature not later than the Business Day next preceding such Servicer 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 EMC Servicer 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 EMC Servicer into the Protected Account, out of the EMC Servicer's own funds. (e) The EMC Servicer shall give at least 30 days advance notice to the Master Servicer of any proposed change of location of the Protected Account prior to any change thereof. Section 7.06. Collection of Taxes, Assessments and Similar Items; Escrow Accounts. To the extent required by the related Mortgage Note, the EMC Servicer 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 EMC Servicer) for the payment of taxes, assessments, hazard insurance premiums or comparable items for the account of the Mortgagors. Nothing herein shall require the EMC Servicer 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 EMC Servicer out of related collections for any payments made pursuant to Section 1.01 of this Exhibit K (with respect to taxes and assessments and insurance premiums) and Section 1.10 of this Exhibit K (with respect to hazard insurance), to refund to any Mortgagors 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 Mortgagors on balances in the Escrow Account or to clear and terminate the Escrow Account at the termination of the Agreement in accordance with Section 10.01 thereof. The Escrow Account shall not be a part of the Trust Fund. K-5 Section 7.07. Access to Certain Documentation and Information Regarding the EMC Mortgage Loans. The EMC Servicer shall afford the Master Servicer, the Depositor and the Trustee reasonable access to all records and documentation regarding the EMC Mortgage Loans and all accounts, insurance policies and other matters relating to the Agreement, such access being afforded without charge, but only upon reasonable request and during normal business hours at the offices of the EMC Servicer designated by it. Section 7.08. Permitted Withdrawals from the Protected Account. (a) The EMC Servicer may from time to time make withdrawals from the Protected Account for the following purposes: (i) to pay to the EMC Servicer (to the extent not previously paid to or withheld by the EMC Servicer), as servicing compensation in accordance with Section 1.16 of this Exhibit K, 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 1.16 of this Exhibit K; (ii) to reimburse the EMC Servicer for Advances made by it with respect to the EMC Mortgage Loans, provided, however, that the EMC Servicer'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) 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 EMC Servicer for any previously made portion of a Servicing Advance or an Advance made by the EMC Servicer that, in the good faith judgment of the EMC Servicer, will not be ultimately recoverable by it from the related Mortgagor, any related Liquidation Proceeds or otherwise (a "Nonrecoverable Advance"), to the extent not reimbursed pursuant to clause (ii) or clause (v); (iv) to reimburse the EMC Servicer from Insurance Proceeds for Insured Expenses covered by the related Insurance Policy; (v) to pay the EMC Servicer any unpaid Servicing Fees and to reimburse it for any unreimbursed Servicing Advances, provided, however, that the EMC Servicer'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 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, the Master Servicer or itself, as applicable, with respect to each EMC Mortgage Loan or property acquired in K-6 respect thereof that has been purchased pursuant to Section 2.02, 2.03 or 3.20 of the 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 EMC Servicer pursuant to Sections 3.03, 7.01, 7.03, 7.04 and 9.05 of the Agreement; (viii) to withdraw pursuant to Section 1.05 of this Exhibit K 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 the Agreement pursuant to Section 10.01 thereof. (b) In addition, no later than 1:00 p.m. Central time on the Servicer Remittance Date for the EMC Servicer, the EMC Servicer shall withdraw from the Protected Account and remit to the Master Servicer the amount of Interest Funds and Principal Funds collected, to the extent on deposit, and the Master Servicer shall deposit such amount in the Master Servicer Collection Account. The EMC Servicer shall keep and maintain separate accounting, on an EMC Mortgage Loan by EMC 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 EMC Servicer shall deliver to the Master Servicer an Officer's Certificate of a Servicing Officer indicating the amount of any previous Advance or Servicing Advance determined by the EMC Servicer to be a Nonrecoverable Advance and identifying the related EMC Mortgage Loan(s), and their respective portions of such Nonrecoverable Advance. (c) [Reserved] Section 7.09. [Reserved.] Section 7.10. Maintenance of Hazard Insurance. The EMC Servicer 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 Mortgaged Property is located with an insurer which is licensed to do business in the state where the 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 EMC Servicer 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 1.05 of this Exhibit K, any amounts collected by the EMC Servicer 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 EMC Servicer's normal servicing procedures) shall be deposited in the Protected Account. Any cost incurred by the EMC Servicer in maintaining any such insurance shall not, for the purpose of calculating monthly distributions to the Certificateholders or remittances to the Trustee for their benefit, be added to the principal K-7 balance of the EMC Mortgage Loan, notwithstanding that the terms of the EMC Mortgage Loan so permit. Such costs shall be recoverable by the EMC Servicer out of late payments by the related Mortgagor or out of Liquidation Proceeds to the extent permitted by Section 1.08 of this Exhibit K. 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 EMC Mortgage Loan in a federally designated special flood hazard area and such area is participating in the national flood insurance program, the EMC Servicer 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 EMC Servicer 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 1.10, 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 EMC Servicer 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 1.10, and there shall have been a loss that would have been covered by such policy, deposit in the Protected Account the amount not otherwise payable under the blanket policy because of such deductible clause. Such deposit shall be from the EMC Servicer's own funds without reimbursement therefor. In connection with its activities as administrator and servicer of the EMC Mortgage Loans, the EMC Servicer 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 7.11. Enforcement of Due-On-Sale Clauses; Assumption Agreements. (a) Except as otherwise provided in this Section 1.11(a), when any property subject to a Mortgage has been or is about to be conveyed by the Mortgagor, the EMC Servicer 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 EMC Servicer 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 EMC Servicer 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 EMC Servicer is authorized, subject to Section 1.11(b) of this Exhibit K, 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 K-8 which such person becomes liable under the Mortgage Note and, unless prohibited by applicable state law, the Mortgagor remains liable thereon, provided that the EMC Mortgage Loan shall continue to be covered (if so covered before the EMC Servicer enters such agreement) by the applicable Required Insurance Policies. The EMC Servicer, subject to Section 1.11(b) of this Exhibit K, 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 EMC Servicer shall not be deemed to be in default under this Section 1.11(a) by reason of any transfer or assumption that the EMC Servicer reasonably believes it is restricted by law from preventing. (b) Subject to the EMC Servicer's duty to enforce any due-on-sale clause to the extent set forth in Section 1.11(a) of this Exhibit K, 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 EMC Mortgage Loan, the EMC Servicer 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 EMC Servicer in accordance with its servicing standards as then in effect. The EMC Servicer 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 EMC Servicer for entering into an assumption or substitution of liability agreement will be retained by the EMC Servicer as additional servicing compensation. Section 7.12. Realization Upon Defaulted EMC Mortgage Loans; Determination of Excess Liquidation Proceeds and Realized Losses; Repurchase of Certain EMC Mortgage Loans. (a) The EMC Servicer 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 EMC Servicer 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 K-9 the EMC Servicer 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 Liquidation Proceeds (respecting which it shall have priority for purposes of withdrawals from the Protected Account pursuant to Section 1.08 of this Exhibit K). If the EMC Servicer 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 EMC Servicer will give notice of any such charge-off to the Master Servicer, the Trustee and the Securities Administrator. The EMC Servicer 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 1.08 of this Exhibit K. If the EMC Servicer has knowledge that a Mortgaged Property that the EMC Servicer 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 EMC Servicer, the EMC Servicer will, prior to acquiring the Mortgaged Property, consider such risks and only take action in accordance with its established environmental review procedures. With respect to any REO Property, 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 EMC Servicer shall ensure that the title to such REO Property references the Agreement and the Trustee's capacity thereunder. Pursuant to its efforts to sell such REO Property, the EMC Servicer shall either itself or through an agent selected by the EMC Servicer 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 EMC Servicer deems to be in the best interest of the EMC Servicer and the Certificateholders for the period prior to the sale of such REO Property. The EMC Servicer shall prepare for and deliver to the Master Servicer, the Securities Administrator and the Trustee a statement with respect to each 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 Master Servicer, the Securities Administrator or 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 no later than the close of business on each Determination Date. The EMC Servicer 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 EMC Servicer 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 K-10 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 (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 of 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 the 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 either 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 EMC Servicer has agreed to indemnify and hold harmless the Trust Fund with respect to the imposition of any such taxes. The decision of the EMC Servicer to foreclose on a defaulted EMC Mortgage Loan shall be subject to a determination by the EMC Servicer 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 EMC Servicer 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 EMC 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. 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 EMC Servicer as provided above, shall be deposited in the Protected Account 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 EMC Servicer 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 EMC Servicer for any related unreimbursed Servicing Advances and Servicing Fees, pursuant to Section 1.08(a)(v) of this Exhibit K or this Section 1.12; second, to reimburse the EMC Servicer for any unreimbursed Advances, pursuant to Section 1.08(a)(ii) of this Exhibit K or this Section 1.12; 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 K-11 amounts are required to be distributed; and fourth, as a recovery of principal of the EMC Mortgage Loan. (b) On each Determination Date, the EMC Servicer shall determine the respective aggregate amounts of Excess Liquidation Proceeds and Realized Losses, if any, for the related Prepayment Period. (c) [Reserved]. (d) The EMC Servicer 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 EMC Servicer from initiating foreclosure proceedings on any date hereafter if the facts and circumstances of such EMC Mortgage Loans including delinquency characteristics in the EMC Servicer's discretion so warrant such action. Section 7.13. REO Property. (a) In the event the Trust Fund acquires ownership of any REO Property in respect of any 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 EMC Servicer 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 EMC Servicer shall protect and conserve such REO Property in the manner and to the extent required herein, subject to the REMIC Provisions. (b) The EMC Servicer shall deposit all funds collected and received in connection with the operation of any such REO Property into the Protected Account. (c) The EMC Servicer, upon the final disposition of any such REO Property, 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 7.14. Presentment of Claims and Collection of Proceeds. The EMC Servicer shall prepare and present on behalf of the Trustee and the Certificateholders all claims under the Insurance Policies, including the Supplemental Primary Mortgage Insurance Policy, 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 EMC Servicer in respect of such Insurance Policies shall be promptly deposited in the Protected 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. K-12 Section 7.15. Documents, Records and Funds in Possession of EMC Servicer to be Held for the Trustee. Notwithstanding any other provisions of the Agreement, the EMC Servicer shall transmit to the Custodian on behalf of the Trustee as required by the Agreement all documents and instruments in respect of an EMC Mortgage Loan coming into the possession of the EMC Servicer from time to time and shall account fully to the Trustee for any funds received by the EMC Servicer or that otherwise are collected by the EMC Servicer as Liquidation Proceeds or Insurance Proceeds in respect of any EMC Mortgage Loan. All Mortgage Files and funds collected or held by, or under the control of, the EMC Servicer 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, shall be held by the EMC Servicer 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 the Agreement. The EMC Servicer also agrees that it shall not create, incur or subject any Mortgage File or any funds that are deposited in the Protected Account 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 EMC Servicer shall be entitled to set off against and deduct from any such funds any amounts that are properly due and payable to the EMC Servicer under the Agreement. Section 7.16. Servicing Compensation. As compensation for its activities hereunder, the EMC Servicer shall be entitled to retain or withdraw from the Protected Account out of each payment of interest on an EMC Mortgage Loan included in the Trust Fund an amount equal to its Servicing Fee at the per annum rate set forth on the Mortgage Loan Schedule (the "Servicing Fee Rate") on the Stated Principal Balance of the related EMC Mortgage Loan for the period covered by such interest payment. Additional servicing compensation in the form of any Excess Liquidation Proceeds, assumption fees, late payment charges, Prepayment Charges, all income and gain net of any losses realized from Permitted Investments with respect to funds in or credited to the Protected Account shall be retained by the EMC Servicer to the extent not required to be deposited in the Protected Account pursuant to Section 1.05 or 1.12(a) of this Exhibit K, and with respect to any Due Date, any interest paid on Simple Interest Loans in excess of 30 days interest. The EMC Servicer 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 1.10 of this Exhibit K and maintenance of the other forms of insurance coverage required by Section 1.10 of this Exhibit K) and shall not be entitled to reimbursement therefor except as specifically provided in Sections 1.08 and 1.12 of this Exhibit K. Section 7.17. Access to Certain Documentation. The EMC Servicer shall provide to the OTS and the FDIC and to comparable regulatory authorities supervising Holders of the Certificates and the examiners and supervisory agents of the OTS, the FDIC and such other authorities, access to any documentation as may be held by the EMC Servicer regarding the EMC Mortgage Loans required by applicable regulations of the OTS and the FDIC. Such access shall be afforded without charge, but only upon reasonable and prior written request and during K-13 normal business hours at the offices of the EMC Servicer designated by it. Nothing in this Section shall limit the obligation of the EMC Servicer to observe any applicable law prohibiting disclosure of information regarding the Mortgagors and the failure of the EMC Servicer to provide access as provided in this Section as a result of such obligation shall not constitute a breach of this Section. Section 7.18. Maintenance of Primary Mortgage Insurance Policies. (a) The EMC Servicer 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 EMC Servicer, would have been covered thereunder. The EMC Servicer shall use its best efforts to keep in force and effect (to the extent that the Mortgage Loan requires the Mortgagor to maintain such insurance), each Primary Mortgage Insurance Policy applicable to any Mortgage Loan. The EMC Servicer 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 a Mortgage Note and is required to be kept in force hereunder. Notwithstanding the foregoing, the EMC Servicer shall not be required to keep in force any Primary Mortgage Insurance Policy beyond the period required by the Fannie Mae Servicing Guide for residential mortgage loans. (b) The EMC Servicer agrees to present, on behalf of the Trustee and the Certificateholders, claims to the insurer under any Primary Mortgage Insurance Policy and, in this regard, to take such reasonable action as shall be necessary to permit recovery under any Primary Mortgage Insurance Policy respecting defaulted Mortgage Loans. Pursuant to Section 1.08 of this Exhibit K, any amounts collected by the EMC Servicer under any Primary Mortgage Insurance Policies shall be deposited in the Protected Account, subject to withdrawal pursuant to Section 1.08 of this Exhibit K. The Trustee shall provide the EMC Servicer with any powers of attorney and or other documentation as it may request in order enable it to perform its obligations pursuant to this Section 1.18. Section 7.19. Fidelity Bond, Errors and Omissions Insurance. The EMC Servicer 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 EMC Servicer 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 EMC Servicer against losses in connection with the failure to maintain any insurance policies required pursuant to the Agreement and the release or satisfaction of an EMC Mortgage Loan which is not serviced in accordance with the requirements of Section 1.01. No provision on this Section 1.19 requiring the fidelity bond and errors and omissions insurance shall diminish or relieve the EMC Servicer from its duties and obligations as set forth in the Agreement. The minimum coverage under any such bond and insurance policy shall be at least equal to the coverage acceptable to Fannie Mae or Freddie Mac for persons performing servicing for loans purchased by Fannie Mae or Freddie Mac. The EMC Servicer 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 K-14 benefit of the Certificateholders must be named as loss payee on the fidelity bond and as additional insured on the errors and omissions policy. ARTICLE VIII. ADVANCES BY THE EMC SERVICER Section 8.01. Advances. The EMC Servicer shall make an Advance and deposit such Advance in the Protected Account. Each such Advance shall be remitted to the Master Servicer Collection Account no later than 1:00 p.m. Central time on the related Servicer Remittance Date in immediately available funds. The EMC Servicer shall be obligated to make any such Advance only to the extent that such advance would not be a Nonrecoverable Advance. If the EMC 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 EMC Servicer shall deliver to the Master Servicer (i) funds constituting the remaining portion of such Advance, if applicable, and (ii) 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 EMC Servicer may (i) cause to be made an appropriate entry in its records relating to the Protected Account that any Amount Held for Future Distributions has been used by the EMC Servicer in discharge of its obligation to make any such Advance and (ii) transfer such funds from the Protected Account to the Master Servicer Collection Account. Any funds so applied and transferred shall be replaced by the EMC Servicer by deposit in the Protected Account no later than the close of business on the Business Day immediately preceding the Servicer Remittance Date on which such funds are required to be remitted to the Master Servicer for deposit into the Master Servicer Collection Account. The EMC Servicer 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 1.08 of this Exhibit K. 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 the Agreement, except as otherwise provided in this Section 2.01. Section 8.02. Reduction of Servicing Compensation in Connection with Prepayment Interest Shortfalls. In the event that, for any Prepayment Period, there is a Prepayment Interest Shortfall arising from a voluntary Principal Prepayment in part or in full by a Mortgagor, the EMC Servicer shall, to the extent of its Servicing Fee and in reduction thereof, remit to the Master Servicer, for deposit into the Master Servicer Collection Account, no later than 1:00 p.m. Central time on the Servicer Remittance Date, an amount equal to the Prepayment Interest Shortfall; and in case of such deposit, the EMC Servicer shall not be entitled to any recovery or reimbursement from the Depositor, the Trustee, the Seller, the Securities Administrator, the Master Servicer, any other Servicer, the Trust Fund or the Certificateholders. ARTICLE IX. REPORTING REQUIREMENTS K-15 Section 9.01. Annual Officer's Certificate as to Compliance. (a) The EMC Servicer shall deliver to the Master Servicer by March 1, 2006, and by March 1 of each year thereafter, an Officer's Certificate, certifying that with respect to the most recently ended calendar year: (i) such Servicing Officer has reviewed the activities of the EMC Servicer during the preceding calendar year or portion thereof and its performance under the Agreement and (ii) to the best of such Servicing Officer's knowledge, based on such review, the EMC Servicer has performed and fulfilled its duties, responsibilities and obligations under the Agreement in all material respects throughout such year, or, if there has been a default in the fulfillment of any such duties, responsibilities or obligations, specifying each such default known to such Servicing Officer and the nature and status thereof. (b) Annual Independent Accountant's Servicing Report. The EMC Servicer, at its expense, shall cause a nationally recognized firm of independent certified public accountants to furnish a statement to the Master Servicer by March 1, 2006, and by March 1 of each year thereafter, to the effect that, with respect to the most recently ended calendar year, such firm has examined certain records and documents relating to the EMC Servicer's performance of its servicing obligations under this Agreement and pooling and servicing and trust agreements in material respects similar to this Agreement and to each other and that, on the basis of such examination conducted substantially in compliance with the audit program for mortgages serviced for Freddie Mac or the Uniform Single Attestation Program for Mortgage Bankers, such firm is of the opinion that the EMC Servicer's activities have been conducted in compliance with the Agreement, or that such examination has disclosed no material items of noncompliance except for (i) such exceptions as such firm believes to be immaterial, (ii) such other exceptions as are set forth in such statement and (iii) such exceptions that the Uniform Single Attestation Program for Mortgage Bankers or the Audit Program for Mortgages Serviced by Freddie Mac requires it to report. If any such report discloses exceptions that are material, the EMC Servicer shall advise the Master Servicer whether such exceptions have been or are susceptible of cure, and will take prompt action to do so. Any Annual Independent Public Accountant's Report furnished pursuant to this Section 3.01(b) shall be in such form as shall permit such report to be filed with the Securities and Exchange Commission as part of the Issuer's annual report on Form 10-K filed pursuant to the Securities Exchange Act of 1934, as amended, and no such Annual Independent Public Accountant's Report shall contain any language restricting, limiting or prohibiting such use of such report (c) Annual Certification. (i) The EMC Servicer will deliver to the Master Servicer, on or before March 1 of each year beginning March 1, 2006 (or, if any such day is not a Business Day, the immediately preceding Business Day), or on any alternative date specified by the Master Servicer upon thirty (30) days written request, a certification containing the information set forth in Attachment 1 to this Exhibit K. Such certification shall be signed by the senior officer in charge of servicing of the EMC Servicer. In addition, the EMC Servicer shall provide such other information with respect to the EMC Mortgage Loans and the servicing and administration thereof within the control of the EMC Servicer which shall be required to enable the Master Servicer to comply with the reporting requirements of the Securities and Exchange Act of 1934, as amended. K-16 (ii) The EMC Servicer shall indemnify and hold harmless the Master Servicer and its officers, directors, agents and affiliates from and against any losses, damages, penalties, fines, forfeitures, reasonable legal fees and related costs, judgments and other costs and expenses arising out of or based upon a breach by the EMC Servicer or any of its officers, directors, agents or affiliates of its obligations under this Section 3.01(c) or the EMC Servicer's negligence, bad faith or willful misconduct in connection therewith. If the indemnification provided for herein is unavailable or insufficient to hold harmless the Master Servicer, then the EMC Servicer 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 EMC Servicer on the other in connection with a breach of the EMC Servicer's obligations under this Section 3.01(c). Section 9.02. 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 EMC Servicer shall submit a liquidation report to the Master Servicer containing such information as shall be mutually acceptable to the EMC Servicer and the Master Servicer with respect to such Mortgaged Property. Section 9.03. Books and Records. The EMC Servicer shall be responsible for maintaining, and shall maintain, a complete set of books and records for the EMC Mortgage Loans which shall be appropriately identified in the EMC Servicer's computer system to clearly reflect the ownership of the EMC Mortgage Loans by the Trust. In particular, the EMC Servicer shall maintain in its possession, available for inspection by the Master Servicer and the Trustee and shall deliver to the Master Servicer and the Trustee upon demand, evidence of compliance with all federal, state and local laws, rules and regulations. To the extent that original documents are not required for purposes of realization of Liquidation Proceeds or Insurance Proceeds, documents maintained by the EMC Servicer may be in the form of microfilm or microfiche or such other reliable means of recreating original documents, including, but not limited to, optical imagery techniques so long as the EMC Servicer complies with the servicing requirements of Section 1.01 of this Exhibit K. The EMC Servicer shall maintain with respect to each EMC Mortgage Loan and shall make available for inspection by the Master Servicer and the Trustee the related servicing file during the time such EMC Mortgage Loan is subject to the Agreement and thereafter in accordance with applicable law. ARTICLE X. INDEMNIFICATION Section 10.01. Indemnification of the Master Servicer. (a) To the extent not covered by the provisions of Section 3.01(c)(ii) of this Exhibit K, the EMC Servicer shall indemnify and hold harmless the Master Servicer from any K-17 loss, liability or expense (except as otherwise provided herein with respect to expenses) (including reasonable legal fees and disbursements of counsel) incurred on its part that may be sustained in connection with, arising out of, or relating to enforcement of the EMC Servicer's obligations under the Agreement (i) related to the EMC Servicer's failure to perform its duties in compliance with the Agreement or (ii) incurred by reason of the EMC Servicer's willful misfeasance, bad faith or gross negligence in the performance of its duties under the Agreement or by reason of its reckless disregard of its obligations and duties under the Agreement, provided, in each case, that with respect to any such claim or legal action (or pending or threatened claim or legal action), the Master Servicer shall have given the EMC Servicer written notice thereof promptly after a Responsible Officer of the Master Servicer shall have with respect to such claim or legal action actual knowledge thereof. The Master Servicer's failure to give such notice shall not affect its right to indemnification hereunder. This indemnity shall survive the resignation or removal of the Trustee, the Master Servicer, the EMC Servicer or the Securities Administrator and the termination of the Agreement. (b) The Trust Fund will indemnify the Master Servicer for any loss, liability or expense of the Master Servicer referred to in Subsection (a) above that has not otherwise been paid by the EMC Servicer.
