Thereafter, the Depositor shall deliver or cause to be delivered to the Trustee such Mortgage, Assignments of Mortgage, or assumption, consolidation or modification agreement, as the case may be, with evidence of recording indicated thereon upon receipt thereof from the public recording office. With respect to any Non-MERS Mortgage Loans which are not Co-op Loans, and as to which the related Mortgaged Property is located in Florida, the Servicer shall cause to be recorded in the appropriate public recording office for real property records each Assignment of Mortgage referred to in this Section 2.01 as soon as practicable. With respect to any Non-MERS Mortgage Loans which are not Co-op Loans as to which the related Mortgaged Property is located outside of Florida, the Servicer shall not be obligated to cause to be recorded the Assignment of Mortgage referred to in this Section 2.01. With respect to Co-op Loans as to which the related dwelling unit is located in Florida, the Servicer shall cause to be filed in the appropriate filing office the Form UCC-3 referred to in this Section 2.01 as soon as practicable. With respect to any Co-op Loans as to which the related dwelling unit is located outside Florida, the Servicer shall not be obligated to cause to be filed the Form UCC-3 referred to in this Section 2.01. While each such Assignment of Mortgage or Form UCC-3 is being recorded or filed, as applicable, the Servicer shall deliver to the Trustee a photocopy of such document. If any such Assignment of Mortgage or Form UCC-3 is returned unrecorded or unfiled to the Servicer because of any defect therein, the Servicer shall cause such defect to be cured and such document to be recorded or filed in accordance with this paragraph. The Depositor shall deliver or cause to be delivered each such original recorded or filed Assignment of Mortgage and intermediate assignment or Form UCC-3 to the Trustee within 270 days of the Closing Date or shall deliver to the Trustee on or before such date an Officer's Certificate stating that such document has been delivered to the appropriate public recording or filing office for recording or filing, but has not been returned solely because of a delay caused by such recording or filing office. In any event, the Depositor shall use all reasonable efforts to cause each such document with evidence of recording or filing thereon to be delivered to the Trustee within 300 days of the Closing Date. With respect to each MERS Mortgage Loan, the Trustee, at the expense of the Depositor and at the direction and with the cooperation of the Servicer, shall cause to be taken such actions as are necessary to cause the Trustee to be clearly identified as the owner of each such Mortgage Loan on the records of MERS for purposes of the system of recording transfers of beneficial ownership of mortgages maintained by MERS. The ownership of each Mortgage Note, the Mortgage and the contents of the related Mortgage File is vested in the Trustee. Neither the Depositor nor the Servicer shall take any action inconsistent with such ownership and shall not claim any ownership interest therein. The Depositor and the Servicer shall respond to any third party inquiries with respect to ownership of the Mortgage Loans by stating that such ownership is held by the Trustee on behalf of the Certificateholders. Mortgage documents relating to the Mortgage Loans not delivered to the Trustee are and shall be held in trust by the Servicer or any Sub-Servicer, for the benefit of the Trustee as the trustee thereof, and the Servicer's or such Sub-Servicer's possession of the contents of each Mortgage File so retained is for the sole purpose of servicing the related Mortgage Loan, and such retention and possession by the Servicer or such Sub-Servicer is in a custodial capacity only. The Depositor agrees to take no action inconsistent with the Trustee's ownership 39 of the Mortgage Loans, to promptly indicate to all inquiring parties that the Mortgage Loans have been sold and to claim no ownership interest in the Mortgage Loans. Each Mortgage File and the mortgage documents relating to the Mortgage Loans contain proprietary business information of the Servicer and its customers. The Trustee and the Depositor agree that they will not use such information for business purposes without the express written consent of the Servicer and that all such information shall be kept strictly confidential. It is the intention of this Agreement that the conveyance of the Depositor's right, title and interest in and to the Trust Fund pursuant to this Agreement shall constitute a purchase and sale and not a loan. If a conveyance of Mortgage Loans from the Seller to the Depositor is characterized as a pledge and not a sale, then the Depositor shall be deemed to have transferred to the Trustee all of the Depositor's right, title and interest in, to and under the obligations of the Seller deemed to be secured by said pledge; and it is the intention of this Agreement that the Depositor shall also be deemed to have granted to the Trustee a first priority security interest in all of the Depositor's right, title, and interest in, to and under the obligations of the Seller to the Depositor deemed to be secured by said pledge and that the Trustee shall be deemed to be an independent custodian for purposes of perfection of the security interest granted to the Depositor. If the conveyance of the Mortgage Loans from the Depositor to the Trustee is characterized as a pledge, it is the intention of this Agreement that this Agreement shall constitute a security agreement under applicable law, and that the Depositor shall be deemed to have granted to the Trustee a first priority security interest in all of the Depositor's right, title and interest in, to and under the Mortgage Loans, all payments of principal of or interest on such Mortgage Loans, all other rights relating to and payments made in respect of the Trust Fund, and all proceeds of any thereof. If the trust created by this Agreement terminates prior to the satisfaction of the claims of any Person in any Certificates, the security interest created hereby shall continue in full force and effect and the Trustee shall be deemed to be the collateral agent for the benefit of such Person. In addition to the conveyance made in the first paragraph of this Section 2.01, the Depositor does hereby convey, assign and set over to the Trustee all of its right, title and interest in that portion of the Trust Fund described in items (ii), (iii), (iv) and (v) of the definition thereof and further assigns to the Trustee for the benefit of the Certificateholders those representations and warranties of the Seller contained in the Sale Agreement and described in Section 3.01 hereof and the benefit of the repurchase obligations of the Seller described in Sections 2.02 and 3.01 hereof and the obligations of the Seller contained in the Sale Agreement to take, at the request of the Depositor or the Trustee, all action on its part which is reasonably necessary to ensure the enforceability of a Mortgage Loan. The parties hereto agree and understand that it is not intended that any mortgage loan be included in the Trust that is any of (i) a "High-Cost Home Loan" as defined in the New Jersey Home Ownership Act effective November 27, 2003, (ii) a "High-Cost Home Loan" as defined in the New Mexico Home Loan Protection Act effective January 1, 2004, (iii) a "High-Cost Home Mortgage Loan" as defined in the Massachusetts Predatory Home Loan Practices Act effective November 7, 2004 or (iv) a "High-Cost Home Loan" as defined by the Indiana High Cost Home Loan Law effective January 1, 2005. Section 2.02 Acceptance by Trustee. Except as set forth in the Exception Report delivered contemporaneously herewith (the "Exception Report"), the Trustee acknowledges receipt by the Custodian on the Trustee's behalf of the Mortgage Note for each Mortgage Loan and delivery of a Mortgage File (but does not acknowledge receipt of all documents required to be included in such Mortgage File) with respect to each Mortgage Loan and declares that the Custodian holds and will hold on the Trustee's behalf such documents and any other documents constituting a part of the Mortgage Files delivered to it in trust for the use and benefit of all present and future Certificateholders. The Depositor will cause the Seller to repurchase any Mortgage Loans to which an exception was taken in the Exception 40 Report unless such exception is cured to the satisfaction of the Trustee within 45 Business Days of the Closing Date. The Trustee may accept delivery of such Mortgage Files by the Custodian on its behalf. The Custodian will deliver a copy of the Exception Report to the Depositor and the Trustee The Custodian, on the Trustee's behalf, agrees, for the benefit of Certificateholders, to review each Mortgage File delivered to it within 270 days after the Closing Date to ascertain that all documents required by Section 2.01 have been executed and received, and that such documents relate to the Mortgage Loans identified in Exhibit A that have been conveyed to it. If the Custodian on the Trustee's behalf finds any document or documents constituting a part of a Mortgage File to be missing or defective (that is, mutilated, damaged, defaced or unexecuted) in any material respect, the Custodian on the Trustee's behalf shall promptly (and in any event within no more than five Business Days) after such finding so notify the Servicer, the Seller, the Trustee and the Depositor. In addition, the Custodian on the Trustee's behalf shall also notify the Servicer, the Seller, the Trustee and the Depositor, if (a) in examining the Mortgage Files, the documentation shows on its face (i) any adverse claim, lien or encumbrance, (ii) that any Mortgage Note was overdue or had been dishonored, (iii) any evidence on the face of any Mortgage Note or Mortgage of any security interest or other right or interest therein, or (iv) any defense against or claim to the Mortgage Note by any party or (b) the original Mortgage with evidence of recording thereon with respect to a Mortgage Loan is not received within 270 days of the Closing Date; provided, however, that if the Depositor cannot deliver the original Mortgage with evidence of recording thereon because of a delay caused by the public recording office where such Mortgage has been delivered for recordation, the Depositor shall deliver or cause to be delivered to the Custodian and the Trustee written notice stating that such Mortgage has been delivered to the appropriate public recording officer for recordation and thereafter the Depositor shall deliver or cause to be delivered such Mortgage with evidence of recording thereon upon receipt thereof from the public recording office. The Depositor shall request that the Seller correct or cure such omission, defect or other irregularity, or substitute a Mortgage Loan pursuant to the provisions of Section 3.03, within 60 days from the date the Seller was notified of such omission or defect and, if the Seller does not correct or cure such omission or defect within such period, that the Seller purchase such Mortgage Loan from the Trustee within 90 days from the date the Depositor notified the Seller and the Trustee of such omission, defect or other irregularity at the Purchase Price of such Mortgage Loan. The Purchase Price for any Mortgage Loan purchased pursuant to this Section 2.02 shall be paid to the Servicer and deposited by the Servicer in the Collection Account promptly upon receipt, and, upon receipt by the Trustee of written notification of such deposit signed by a Servicing Officer, the Trustee shall promptly release to the Seller the related Mortgage File and the Trustee shall execute and deliver such instruments of transfer or assignment, without recourse, as shall be necessary to vest in the Seller or its designee, as the case may be, any Mortgage Loan released pursuant hereto, and the Trustee shall have no further responsibility with regard to such Mortgage Loan. It is understood and agreed that the obligation of the Seller to purchase, cure or substitute any Mortgage Loan as to which a material defect in or omission of a constituent document exists shall constitute the sole remedy respecting such defect or omission available to the Trustee on behalf of Certificateholders. The Trustee shall be under no duty or obligation to inspect, review and examine such documents, instruments, certificates or other papers to determine that they are genuine, enforceable or appropriate to the represented purpose, or that they have actually been recorded, or that they are other than what they purport to be on their face. The Trustee shall keep confidential the name of each Mortgagor and shall not solicit any such Mortgagor for the purpose of refinancing the related Mortgage Loan. Within 280 days of the Closing Date, the Trustee based solely on information provided to it by the Custodian shall deliver to the Depositor and the Servicer the Trustee's Certification, substantially in the form of Exhibit G attached hereto, setting forth the status of the Mortgage Files as of such date. 41 Section 2.03 Trust Fund; Authentication of Certificates. The Trustee acknowledges and accepts the assignment to it of the Trust Fund created pursuant to this Agreement in trust for the use and benefit of all present and future Certificateholders.

Section 2.04 REMIC Elections. (a) The Depositor hereby instructs and authorizes the Paying Agent to make appropriate elections to treat the Trust Fund as comprising two REMICs (the Lower-Tier REMIC and the Upper-Tier REMIC). This Agreement shall be construed so as to carry out the intention of the parties that each REMIC created hereunder be treated as a REMIC at all times prior to the date on which the Trust Fund is terminated. The Closing Date is hereby designated as the "startup day" of each REMIC created hereunder within the meaning of Section 860G(a)(9) of the Code. The Lower-Tier REMIC shall hold as assets all property of the Trust Fund other than (i) the Lower-Tier REMIC Interests and (ii) the Yield Maintenance Agreement and the Reserve Fund. Each of the Lower-Tier REMIC Regular Interests is hereby designated a "regular interest" (within the meaning of Section 860G(a)(1) of the Code) in the Lower-Tier REMIC. The Upper-Tier REMIC shall hold as assets the several classes of uncertificated Lower-Tier REMIC Regular Interests. Each of the Upper-Tier REMIC Regular Interests is hereby designated as a "regular interest" (within the meaning of Section 860G(a)(1) of the Code) in the Upper-Tier REMIC. The Class LT-R Interest is hereby designated as the sole residual interest (within the meaning of Section 860G(a)(2) of the Code) in the Lower-Tier REMIC. The Residual Interest is hereby designated as the sole residual interest (within the meaning of Section 860G(a)(2) of the Code) in the Upper-Tier REMIC. The Class A-R Certificate evidences ownership of the Class LT-R Interest and the Residual Interest. All interests described in this Section 2.04(a) shall be designated as such on the Startup Day. 42 LOWER-TIER REMIC The following table specifies the class designation, interest rate, initial principal amount and Classes of corresponding certificates for each class of Lower-Tier REMIC Interest:

---------- (1) The Class LT-R Interest shall represent the sole class of residual interest in the Lower-Tier REMIC. The Class LT-R Interest will not have a principal amount or an interest rate. The Class LT-R Interest shall be represented by the Class A-R Certificate. (2) The initial principal amount of each of these interests shall be equal to the Original Certificate Principal Balance the Class of corresponding Certificates (computed as if no Exchangeable Certificates existed and by disregarding the notional amount of any class of "interest-only" certificates). (3) The Class LTA-X Interest is an interest only interest, has no principal balance, is not entitled to payments of principal and will bear interest on its notional amount. The notional amount of the Class LTA-X Interest shall equal the Class A-X Notional Amount. Principal and interest (disregarding payments in respect of Basis Risk Shortfall Carryover Amounts) shall be payable to, and shortfalls, losses, prepayments and increases in principal amount are allocable to, the Lower-Tier REMIC Regular Interests as such amounts are payable and allocable to the corresponding certificates under this Agreement (computed as if no Exchangeable Certificates existed and by excluding Section 6.01(I)(a)(v) hereof). 43 (b) Solely for the purposes of Section 1.860G-1(a)(4)(iii) of the Treasury Regulations, the "latest possible maturity date" of each "regular interest" in each REMIC created hereunder is the Distribution Date immediately following the latest scheduled maturity of any Mortgage Loan. (c) The "tax matters person" with respect to each REMIC created hereunder for purposes of the REMIC Provisions shall be the beneficial owner of the Class A-R Certificate having the largest Percentage Interest of such Class; provided, however, that such largest beneficial owner and, to the extent relevant, each other Holder of a Class A-R Certificate, by its acceptance thereof, irrevocably appoints the Servicer as its agent and attorney-in-fact to act as "tax matters person" with respect to each REMIC created hereunder for purposes of the REMIC provisions. (d) It is intended that each REMIC created hereunder shall constitute, and that the affairs of the Trust Fund shall be conducted so as to qualify each REMIC created hereunder as, a "real estate mortgage investment conduit" as defined in and in accordance with the REMIC Provisions. In furtherance of such intention, the Servicer covenants and agrees that it shall act as agent (and the Servicer is hereby appointed to act as agent) on behalf of the Trust Fund, each REMIC created hereunder and the Holder of the Class A-R Certificate and that in such capacity it shall: (i) prepare and file, or cause to be prepared and filed, in a timely manner, a U.S. Real Estate Mortgage Investment Conduit Income Tax Return (Form 1066) for each REMIC created hereunder 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 REMIC created hereunder, using the calendar year as the taxable year and the accrual method of accounting, 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 shall 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; (ii) within thirty days of the Closing Date, shall furnish or cause to be furnished to the Internal Revenue Service, on Form 8811 or as otherwise may be required by the Code, the name, title, address, and telephone number of the person that the Holders of the Certificates may contact for tax information relating thereto (and the Servicer shall act as the representative of the Trust Fund for this purpose), together with such additional information as may be required by such Form, and shall update such information at the time or times in the manner required by the Code; (iii) make or cause to be made an election, on behalf of each REMIC created hereunder, to be treated as a REMIC, and make the appropriate designations, if applicable, in accordance with this Section 2.04 on the federal tax return of each REMIC hereunder for its first taxable year (and, if necessary, under applicable state law); (iv) 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 or reports, or furnish or cause to be furnished by telephone, mail, publication or other appropriate method such information, 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; (v) provide information necessary for the computation of tax imposed on the transfer of the Class A-R Certificate to a Disqualified Organization, or an agent (including a broker, 44 nominee or other middleman) of a Disqualified Organization, or a pass-through entity in which a Disqualified Organization 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); (vi) ensure that federal, state or local income tax or information returns shall be signed by the Trustee or such other Person as may be required to sign such returns by the Code or state or local laws, regulations or rules; and (vii) maintain such records relating to each REMIC created hereunder as may be required by the Code and as may be necessary to prepare the foregoing returns, schedules, statements or information. (e) Pursuant to Section 6.02(b), the Servicer, with the consent of the Trustee, hereby appoints the Global Corporate Trust MBS Group of The Bank of New York Trust Company, N.A. to perform the duties enumerated in (d) above. (f) It is intended that the rights of each Class of the Class A-4 Certificates to receive payments in respect of Basis Risk Shortfall Carryover Amounts shall be treated as a right in interest rate cap contracts and such shall be accounted for as property held separate and apart from the regular interests in the Upper-Tier REMIC held by the Holders of the Class A-4 Certificates. This provision is intended to satisfy the requirements of Treasury Regulations Section 1.860G-2(i) for the treatment of property rights coupled with REMIC interests to be separately respected and shall be interpreted consistently with such regulation. Section 2.05 Permitted Activities of Trust. The Trust is created for the object and purpose of engaging in the Permitted Activities. Section 2.06 Qualifying Special Purpose Entity. For purposes of SFAS 140, the parties hereto intend that the Trust shall be treated as a "qualifying special purpose entity" as such term is used in SFAS 140 and any successor rule thereto and its power and authority as stated in Section 2.05 of this Agreement shall be limited in accordance with paragraph 35 thereof. [END OF ARTICLE II] ARTICLE III REPRESENTATIONS AND WARRANTIES OF THE DEPOSITOR AND THE SERVICER; REPURCHASE OF MORTGAGE LOANS Section 3.01 Representations and Warranties of the Depositor with respect to the Mortgage Loans. The Depositor hereby represents and warrants to the Trustee for the benefit of the Certificateholders that on or before the Closing Date it has entered into the Sale Agreement with the Seller, that the Seller has made the following representations and warranties with respect to each Mortgage Loan in the Sale Agreement as of the Closing Date, which representations and warranties run to and are for the benefit of the Depositor and the Trustee for the benefit of the Certificateholders, and as to which the Depositor has assigned to the Trustee for the benefit of the Certificateholders, pursuant to Section 2.01 hereof, the right to cause the Seller to repurchase a Mortgage Loan as to which there has occurred an uncured breach of representations and warranties in accordance with the provisions of the Sale Agreement. 45 (a) The information set forth in the Mortgage Loan Schedule is complete, true and correct in all material respects; (b) With respect to a Mortgage Loan which is not a Co-op Loan, the Mortgage creates a first lien or a first priority ownership interest in an estate in fee simple in real property securing the related Mortgage Note. With respect to a Co-op Loan, the related Mortgage is a valid, enforceable and subsisting first security interest on the related cooperative shares securing the related Mortgage Note, subject only to (a) liens of the related residential cooperative housing corporation for unpaid assessments representing the Mortgagor's pro rata share of the related residential cooperative housing corporation's payments for its blanket mortgage, current and future real property taxes, insurance premiums, maintenance fees and other assessments to which like collateral is commonly subject and (b) other matters to which like collateral is commonly subject which do not materially interfere with the benefits of the security intended to be provided by the related security agreement. There are no liens against or security interest in the cooperative shares relating to each Co-op Loan (except for unpaid maintenance, assessments and other amounts owed to the related cooperative which individually or in the aggregate will not have a material adverse effect on such Co-op Loan), which have priority over the Trustee's security interest in such cooperative shares; (c) All payments due prior to the Cut-off Date for such Mortgage Loan have been made as of the Closing Date, the Mortgage Loan is not delinquent in payment more than 30 days and has not been dishonored; to the best of the Seller's knowledge, there are no material defaults under the terms of the Mortgage Loan; 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 (or, with respect to a Co-op Loan, the related Mortgagor), directly or indirectly, for the payment of any amount required by the Mortgage Loan; there has been no more than one delinquency in excess of 30 days during the preceding twelve-month period; (d) To the best of the Seller's knowledge, all taxes, governmental assessments, insurance premiums, water, sewer and municipal charges, leasehold payments or ground rents which previously became due and owing have been paid, or escrow funds have been established in an amount sufficient to pay for every such escrowed item which remains unpaid and which has been assessed but is not yet due and payable; (e) The terms of the Mortgage Note and the Mortgage have not been impaired, waived, altered or modified in any respect, except by written instruments. No Mortgagor has been released, in whole or in part, from the terms thereof except in connection with an assumption agreement and which assumption agreement is part of the Mortgage File and the terms of which are reflected in the Mortgage Loan Schedule; (f) The Mortgage Note and the Mortgage are not subject to any right of rescission, set-off, counterclaim or defense, including, without limitation, the defense of usury, nor will the operation of any of the terms of the Mortgage Note or Mortgage, or the exercise of any right thereunder, render the Mortgage Note or 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, and the Mortgagor was not a debtor in any state or federal bankruptcy or insolvency proceeding at the time the Mortgage Loan was originated; (g) With respect to a Mortgage Loan which is not a Co-op Loan, all buildings or other customarily insured improvements upon the Mortgaged Property are insured by an insurer acceptable under the FNMA Guides against loss by fire, hazards of extended coverage and such other hazards as are provided for in the FNMA Guides or by FHLMC. All such standard hazard policies are in full force and 46 effect and on the date of origination contained a standard mortgagee clause naming the Seller and its successors in interest and assigns as loss payee and such clause is still in effect and all premiums due thereon have been paid. If required by the Flood Disaster Protection Act of 1973, as amended, the Mortgaged Property is covered by a flood insurance policy meeting the requirements of the current guidelines of the Federal Insurance Administration which policy conforms to FNMA and FHLMC requirements. The Mortgage obligates the Mortgagor thereunder to maintain all such insurance at the 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 the Mortgagor's cost and expense and to seek reimbursement therefor from the Mortgagor; (h) Any and all requirements of any federal, state or local laws and all applicable predatory and abusive lending laws, including, without limitation, usury, truth-in-lending, real estate settlement procedures, consumer credit protection, equal credit opportunity or disclosure laws applicable to the Mortgage Loan have been complied with in all material respects; (i) The Mortgage has not been satisfied, canceled or subordinated, in whole or in part, or rescinded, 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; (j) With respect to a Mortgage Loan which is not a Co-op Loan, the Mortgage is a valid, subsisting, enforceable and perfected first lien on the Mortgaged Property, including, all buildings on the Mortgaged Property. The Mortgage and the Mortgage Note do not contain any evidence of any security interest or other interest or right thereto. Such lien is free and clear of all adverse claims, liens and encumbrances having priority over the first lien of the Mortgage subject only to (1) the lien of non-delinquent 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 which are acceptable to mortgage lending institutions generally and either (A) which are referred to or otherwise considered in the appraisal made for the originator of the Mortgage Loan, or (B) which do not adversely affect the Appraised Value of the Mortgaged Property as set forth in such appraisal, and (3) 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 or the use, enjoyment, value or marketability of the related Mortgaged Property. Any security agreement, chattel mortgage or equivalent document related to and delivered in connection with the Mortgage Loan establishes and creates a valid, subsisting, enforceable and perfected first lien and first priority security interest on the property described therein, and the Depositor has the full right to sell and assign the same to the Trustee for the benefit of the Certificateholders; (k) The Mortgage Note and the related Mortgage are original and genuine and each is the legal, valid and binding obligation of the maker thereof, enforceable in all respects in accordance with its terms subject to bankruptcy, insolvency and other laws of general application affecting the rights of creditors and the Depositor has taken all action necessary to transfer such rights of enforceability to the Trustee for the benefit of the Certificateholders. All parties to the Mortgage Note and the Mortgage had the legal capacity to enter into the Mortgage Loan and to execute and deliver the Mortgage Note and the Mortgage. The Mortgage Note and the Mortgage have been duly and property executed by such parties. 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 improvements and as to disbursements of any escrow funds therefor have been complied with; (l) The Seller is the sole owner and holder of the Mortgage Loan and the indebtedness evidenced by the Mortgage Note, except for the Assignments of Mortgage which have been sent for 47 recording, and upon recordation the Seller will be the owner of record of the Mortgage and the indebtedness evidenced by the Mortgage Note, and upon the sale of the Mortgage Loan to the Trust for the benefit of the Certificateholders, the Seller will retain the Mortgage File or any part thereof with respect thereto not delivered to the Trust for the benefit of the Certificateholders or its designee in trust only for the purpose of servicing and supervising the servicing of the Mortgage Loan. Immediately prior to the transfer and assignment to the Trust for the benefit of the Certificateholders, the Mortgage Loan, including the Mortgage Note and the Mortgage, were not subject to an assignment or pledge, and the Depositor had good and marketable title to and was the sole owner thereof and had full right to transfer and sell the Mortgage Loan to the Trustee for the benefit of the Certificateholders free and clear of any encumbrance, equity, lien, pledge, charge, claim or security interest and has the full right and authority subject to no interest or participation of, or agreement with, any other party, to sell and assign the Mortgage Loan pursuant to this Agreement and following the sale of the Mortgage Loan, the Trustee for the benefit of the Certificateholders will own such Mortgage Loan free and clear of any encumbrance, equity, participation interest, lien, pledge, charge, claim or security interest; (m) With respect to a Mortgage Loan which is not a Co-op Loan, the Mortgage Loan is covered by an ALTA lender's title insurance policy or other generally acceptable form of policy or insurance acceptable to FNMA or FHLMC, issued by a title insurer acceptable to FNMA or FHLMC and qualified to do business in the jurisdiction where the Mortgaged Property is located, insuring (subject to the exceptions contained in (j) (1), (2) and (3) above) the Seller, its successors and assigns, as to the first priority lien of the Mortgage in the original principal amount of the Mortgage Loan. Such lender's title insurance policy insures ingress and egress by or upon the Mortgaged Property or any interest therein. Where required by state law or regulation, the Mortgagor has been given the opportunity to choose the carrier of the required mortgage title insurance. The Seller, its successors and assigns, are the sole insureds of such lender's title insurance policy, and such lender's title insurance policy is in full force and effect and will be in full force and effect upon the consummation of the transactions contemplated by this Agreement. No claims have been made under such lender's title insurance policy, and no prior holder of the related Mortgage, including the Seller, has done, by act or omission, anything which would impair the coverage of such lender's title insurance policy; (n) There is no default, breach, violation or event of acceleration existent, under the Mortgage or the related Mortgage Note and 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 permitting acceleration; and neither the Seller nor any prior mortgagee has waived any default, breach, violation or event permitting acceleration; (o) 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 liens) affecting the related Mortgaged Property (or the related residential dwelling unit in the Underlying Mortgage Property, in the case of a Co-op Loan) which are or may be liens prior to or equal to the lien of the related Mortgage; (p) With respect to a Mortgage Loan which is not a Co-op Loan, all improvements subject to the Mortgage which were considered in determining the Appraised Value of the Mortgaged Property lie wholly within the boundaries and building restriction lines of the Mortgaged Property (and wholly within the project with respect to a condominium unit) and no improvements on adjoining properties encroach upon the Mortgaged Property except those which are insured against by the title insurance policy referred to in clause (m) above and all improvements on the property comply with all applicable zoning and subdivision laws and ordinances; the Mortgaged Property is lawfully occupied under applicable law; (q) The Mortgage Loan complies in all material respects with all the terms, conditions and requirements of the Seller's underwriting standards in effect at the time of origination of such Mortgage 48 Loan. The Mortgage Notes and Mortgages (exclusive of any riders) are on forms generally acceptable to FNMA or FHLMC. Monthly Payments under the Mortgage Note are due and payable on the first day of each month. The Mortgage contains the usual and enforceable provisions of the originator at the time of origination for the acceleration of the payment of the unpaid principal amount of the Mortgage Loan if the related Mortgaged Property is sold without the prior consent of the mortgagee thereunder; (r) The Mortgaged Property (or Underlying Mortgaged Property, in the case of a Co-op Loan), is not subject to any material damage by waste, fire, earthquake, windstorm, flood or other casualty. To the best of the Seller's knowledge, at origination of the Mortgage Loan there was, and there currently is, no proceeding pending for the total or partial condemnation of the Mortgaged Property (or Underlying Mortgaged Property, in the case of a Co-op Loan); (s) The related Mortgage contains customary and enforceable provisions such as to render the rights and remedies of the holder thereof adequate for the realization against the Mortgaged Property of the benefits of the security provided thereby, including, (l) 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 homestead or 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 subject to applicable federal and state laws and judicial precedent with respect to bankruptcy and right of redemption or similar law; (t) If the Mortgage constitutes a deed of trust, a trustee, authorized and duly qualified if required under applicable law to act as such, has been properly designated and currently so serves and is named in the Mortgage, and no fees or expenses, except as may be required by local law, are or will become payable by the Purchaser to the trustee under the deed of trust, except in connection with a trustee's sale or attempted sale after default by the Mortgagor; (u) The Mortgage File contains an appraisal or a recertification document (in the case of a Mortgage Loan originated under CHF's Streamlined Refinance Program) of the related Mortgaged Property (or the related residential dwelling unit in the Underlying Mortgaged Property, in the case of a Co-op Loan), signed prior to the final approval of the mortgage loan application by an appraiser approved by the Seller who had no interest, direct or indirect, in the Mortgaged Property (or Underlying Mortgaged Property, in the case of a Co-op Loan), or in any loan made on the security thereof, and whose compensation is not affected by the approval or disapproval of the Mortgage Loan. The appraisal is in a form acceptable to FNMA or FHLMC; (v) 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) (A) in substantial compliance with any and all applicable licensing requirements of the laws of the state wherein the Mortgaged Property (or Underlying Mortgaged Property, in the case of a Co-op Loan), is located, and (B) (1) organized under the laws of such state, or (2) qualified to do business in such state, or (3) federal savings and loan associations or national banks or a Federal Home Loan Bank or savings bank having principal offices in such state, or (4) not doing business in such state; (w) The related Mortgage Note is not and has not been secured by any collateral except the lien of the corresponding Mortgage and the security interest of any applicable security interest of any applicable agreement or chattel mortgage referred to above and such collateral does not serve as security for any other obligation; (x) The Mortgagor has received all disclosure materials required by applicable law with respect to the making of such mortgage loans; 49 (y) The Mortgage Loan does not contain "graduated payment" features; (z) The Mortgagor is not in bankruptcy and, to the best of the Seller's knowledge, the Mortgagor is not insolvent; (aa) The Mortgage Loans are fixed rate mortgage loans. Each Mortgage Loan has an original term to maturity of not more than thirty (30) years with interest payable in arrears on the first day of each month. No Mortgage Loan contains terms or provisions which would result in negative amortization; (bb) Each Mortgage Note, each Mortgage, each Assignment of Mortgage and any other documents required pursuant to this Agreement to be delivered to the Trustee on behalf of the Certificateholders or its designee, or its assignee for each Mortgage Loan, have been, on or before the Closing Date, delivered to the Trustee on behalf of the Certificateholders or its designee, or its assignee; (cc) All escrow payments have been collected in full compliance with state and federal law and the provisions of the related Mortgage Note and Mortgage. As to any Mortgage Loan that is the subject of an escrow, escrow of funds is not prohibited by applicable law and has been established in an amount sufficient to pay for every escrowed item that remains unpaid and has been assessed but is not yet due and payable. No escrow deposits or other charges or payments due under the Mortgage Note have been capitalized under any Mortgage or the related Mortgage Note. Any interest required to be paid pursuant to state, federal and local law has been properly paid and credited; (dd) [Reserved]; (ee) In the event that at origination the Mortgage Loan has a Loan-to-Value Ratio greater than 80%, the excess of the principal balance of the Mortgage Loan over 75% of the Appraised Value of the Mortgaged Property, with respect to a refinanced Mortgage Loan, or the lesser of the Appraised Value or the purchase price of the Mortgaged Property (or Underlying Mortgaged Property, in the case of a Co-op Loan), with respect to a purchase money Mortgage Loan, is and will be insured as to payment defaults by a Primary Insurance Policy issued by a Qualified Insurer, except where the primary mortgage insurance was (i) impermissible at origination at applicable law, in which case such Mortgage Loan was originated in accordance with applicable law, (ii) cancelled at the request of the Mortgagor pursuant to the cancellation requirements of FNMA, FHLMC, state law or, as applicable the Home Owner and Equity Protection Act of 1994, as amended, or (iii) automatically terminated in accordance with the termination requirements of FNMA, FHLMC, state law or, as applicable the Home Owner and Equity Protection Act of 1994, as amended. All provisions of such Primary Insurance Policy have been and are being complied with, such policy is in full force and effect, and all premiums due thereunder have been paid. No action, inaction, or event has occurred and no state of facts exists that has, or will result in the exclusion from, denial of, or defense to coverage. Any Mortgage Loan subject to a Primary Insurance Policy obligates the Mortgagor thereunder to maintain the Primary Insurance Policy and to pay all premiums and charges in connection therewith. The Mortgage Rate for the Mortgage Loan as set forth on the Mortgage Loan Schedule is net of any such insurance premium; (ff) The Assignment of Mortgage is in recordable form and is acceptable for recording (or, in the case of a Co-op Loan, is in a form acceptable for filing) under the laws of the jurisdiction in which the Mortgaged Property (or underlying Mortgaged Property, in the case of a Co-op Loan) is located; (gg) As to Mortgage Loans that are not secured by an interest in a leasehold estate, the Mortgaged Property (or Underlying Mortgaged Property, in the case of a Co-op Loan), is located in the state identified in the Mortgage Loan Schedule and consists of a single parcel of real property with a detached single family residence erected thereon, or a two-to four-family dwelling, or an individual 50 condominium unit in a condominium project, or a dwelling unit in a residential cooperative housing corporation or an individual unit in an attached planned unit development or a detached planned unit development, provided, however, that no residence or dwelling is a single parcel of real property with a mobile home thereon.

The Mortgage Note is payable on the first day of each month in equal monthly installments of principal and interest, with interest calculated and payable in arrears, sufficient to amortize the Mortgage Loan fully by the stated maturity date, over an original term of not more than thirty years from commencement of amortization; (oo) As of the Closing Date, the Mortgage Loan is a "qualified mortgage" within the meaning of Section 860G(a)(3) of the Code (without regard to Treasury Regulations Section 1.860G-2(f) or any similar rule that provides that a defective obligation is a qualified mortgage for a temporary period); 51 (pp) With respect to a Mortgage Loan that is a Co-op Loan, the stock that is pledged as security for the Mortgage Loan is held by a Person as a tenant-stockholder (as defined in Section 216 of the Code) in a cooperative housing corporation (as defined in Section 216 of the Code); (qq) As of the Closing Date, the Mortgage Loan is not the subject of pending or final foreclosure proceedings and the Seller would not, based on the delinquency status of the Mortgage Loan, institute foreclosure proceedings with respect to the Mortgage Loan prior to the next scheduled payment for the Mortgage Loan; (rr) As of the Closing Date, the Mortgage Loan does not provide for interest other than at either (i) a single fixed rate in effect throughout the term of the Mortgage Loan or (ii) a "variable rate" (within the meaning of Treasury Regulation Section 1.860G-1(a)(3)) in effect throughout the term of the Mortgage Loan; (ss) No Mortgage Loan is a "covered loan" within the meaning of the Georgia Fair Lending Act of 2002, as amended; (tt) None of the Mortgage Loans are (a) covered by the Home Ownership and Equity Protection Act of 1994 or (b) classified as a "high cost" loan or similarly classified using different terminology under any federal, state or local law imposing heightened regulatory scrutiny or additional legal liability for residential mortgage loans having high interest rates, points and/or fees such as predatory lending laws; None of the Mortgage Loans are "high cost" loans as defined by the applicable federal, state or local predatory and abusive lending laws nor is any Mortgage Loan a "High Cost Loan" or "Covered Loan," as applicable (as such terms are defined in the current Standard & Poor's LEVELS(R) Glossary which is now version 5.6 revised, appendix E) and no Mortgage Loan originated on or after October 1, 2002 through March 6, 2003 is governed by the Georgia Fair Lending Act of 2002, as amended; and (uu) As to each Mortgage Loan that is secured by an interest in a leasehold estate, (i) the use of a leasehold estate for residential properties is an accepted practice in the area where the related Mortgaged Property is located, (ii) residential property consisting of leasehold estates is marketable in the area where the related Mortgaged Property is located, (iii) the related lease has been recorded in the applicable land records, (iv) the lease is valid and in good standing and is not subject to any prior lien by which the lease could be terminated or subject to any charge or penalty, and (v) the remaining term of the lease does not terminate less than five years after the maturity date of such Mortgage Loan. Upon discovery by any of the Depositor, the Servicer or the Trustee of a breach of any of the foregoing representations and warranties which materially and adversely affects the value of a Mortgage Loan or the interest of the Certificateholders (or which materially and adversely affects the interests of the Certificateholders in the related Mortgage Loan in the case of a representation and warranty relating to a particular Mortgage Loan), the party discovering such breach shall give prompt written notice to the other parties and to the Seller, which notice shall specify the date of discovery. Pursuant to the Sale Agreement, the Seller shall within 90 days from the earlier of (i) the date of receipt of notice of such breach or (ii) the date the Seller otherwise discovers such breach, cure such breach, substitute a Mortgage Loan pursuant to the provisions of Section 3.03 or, if the breach relates to a particular Mortgage Loan, purchase such Mortgage Loan from the Trustee at the Purchase Price.

It is understood and agreed that the obligation of the Seller to cure, substitute or purchase any Mortgage Loan as to which such a breach has occurred shall constitute the sole remedy respecting such breach available to Certificateholders or the Trustee on behalf of Certificateholder. Section 3.02 Representations and Warranties of the Servicer. The Servicer represents and warrants to, and covenants with, the Trustee for the benefit of the Certificateholders that as of the Closing Date: (a) The Servicer is a limited liability company duly chartered and validly existing in good standing under the laws of the State of Delaware, and the Servicer is duly qualified or registered as a foreign corporation in good standing in each jurisdiction in which the ownership or lease or its properties or the conduct of its business requires such qualification; (b) The execution and delivery of this Agreement by the Servicer and its performance and compliance with the terms of this Agreement will not violate the Servicer's certificate of formation or by-laws or constitute a default (or an event which, with notice or lapse of time, or both, would constitute a default) under, or result in the breach of, any material contract, agreement or other instrument to which the Servicer is a party or which may be applicable to the Servicer or any of its assets; (c) This Agreement, assuming due authorization, execution and delivery by the Trustee and the Depositor, constitutes a valid, legal and binding obligation of the Servicer, enforceable against it in accordance with the terms hereof subject to applicable bankruptcy, insolvency, reorganization, moratorium and other laws affecting the enforcement of creditors' rights generally and to general principles of equity, regardless of whether such enforcement is considered in a proceeding in equity or at law; (d) The Servicer is not in default with respect to any order or decree of any court or any order, regulation or demand of any federal, state, municipal or governmental agency, which default might have consequences that would materially and adversely affect the condition (financial or other) or operations of the Servicer or its properties or might have consequences that would affect its performance hereunder; and (e) No litigation is pending or, to the best of the Servicer's knowledge, threatened against the Servicer which would prohibit its entering into this Agreement or performing its obligations under this Agreement.

Section 3.03 Option to Substitute. If the Seller is required to repurchase any Mortgage Loan pursuant to Section 2.02 or 3.01, the Seller may, at its option, within two years from the Closing Date, remove such defective Mortgage Loan from the terms of this Agreement and substitute another mortgage loan for such defective Mortgage Loan, in lieu of repurchasing such defective Mortgage Loan. Any substitute Mortgage Loan shall (a) have a Principal Balance at the time of substitution not in excess of the Principal Balance of the removed Mortgage Loan (the amount of any difference, plus one month's interest thereon at the Mortgage Rate borne by the removed Mortgage Loan, being paid by the Seller and deemed to be a Principal Prepayment to be deposited by the Servicer in the Collection Account), (b) have a Mortgage Rate not less than, and not more than one percentage point greater than, the Mortgage Rate of the removed Mortgage Loan (provided, however, that if the Mortgage Rate on the substitute Mortgage Loan exceeds the Mortgage Rate on the removed Mortgage Loan, the amount of that excess interest (the 53 "Substitute Excess Interest") shall be payable to the Class A-R Certificate), (c) have a remaining term to stated maturity not later than, and not more than one year less than, the remaining term to stated maturity of the removed Mortgage Loan, (d) be, in the reasonable determination of the Servicer, of the same type, quality and character (including location of the Mortgaged Property (or underlying Mortgaged Property, in the case of a Co-op Loan)) as the removed Mortgage Loan as if the breach had not occurred, (e) have a Loan-to-Value Ratio at origination no greater than that of the removed Mortgage Loan and (f) be, in the reasonable determination of the Seller, in material compliance with the representations and warranties contained in the Sale Agreement and described in Section 3.01, as of the date of substitution. The Seller shall amend the Mortgage Loan Schedule to reflect the withdrawal of the removed Mortgage Loan from this Agreement and the substitution of such substitute Mortgage Loan therefor and shall send a copy of such amended Mortgage Loan Schedule to the Servicer and the Trustee. The Sale Agreements provide that upon such amendment the Seller shall be deemed to have made as to such substitute Mortgage Loan the representations and warranties set forth in Section 3.01 as of the date of such substitution, which shall be continuing as long as any Certificate shall be outstanding or this Agreement has not been terminated, and the remedies for breach of any such representation or warranty shall be as set forth in Section 3.01.

In the event of such a substitution, accrued interest on the substitute Mortgage Loan for the month in which the substitution occurs and any Principal Prepayments made thereon during such month shall be the property of the Trust Fund, and accrued interest for such month on the Mortgage Loan for which the substitution is made and any Principal Prepayments made thereon during such month shall be the property of the Seller. The principal payment on a substitute Mortgage Loan due on the Due Date in the month of substitution shall be the property of the Seller, and the principal payment on the Mortgage Loan for which the substitution is made due on such date shall be the property of the Trust Fund.

(b) Upon surrender for registration of transfer of any Certificate at any office or agency of the Trustee, or if a Paying Agent has been appointed hereunder pursuant to Section 4.05, the Paying Agent maintained for such purpose, the Depositor shall execute and the Trustee or if an Authenticating Agent is appointed under Section 4.06, the Authenticating Agent shall authenticate and deliver, in the name of the designated transferee or transferees, a Certificate of a like Class and aggregate Percentage Interest and dated the date of authentication by the Authenticating Agent. (c) No transfer of a Class B-3, Class B-4 or Class B-5 Certificate shall be made unless such transfer is made pursuant to an effective registration statement or otherwise in accordance with the requirements under the Securities Act. If such a transfer is to be made in reliance upon an exemption from said Act, (i) the Depositor may require (except with respect to the initial transfer of a Class B-3, Class B-4 or Class B-5 Certificate from J.P. Morgan Securities Inc. and except if the transferee executes a certificate substantially in the form of Exhibit H hereto) a written opinion of independent counsel acceptable to and in form and substance reasonably satisfactory to the Depositor and the Trustee that such transfer may be made pursuant to an exemption, describing the applicable exemption and the basis therefor, from said Act and laws or is being made pursuant to said Act and laws, which opinion of counsel shall not be an expense of the Trust Fund, the Trustee, the Depositor or the Servicer, and (ii) the Depositor shall require the transferee to execute a certification substantially in the form of Exhibit H or Exhibit I. (d) (i) No transfer of an ERISA Restricted Certificate or a Class A-R Certificate shall be made unless the prospective transferee provides the Depositor and the Trustee with (I) a representation as set forth in Exhibit K for Class A-R Certificates or in Exhibit M for ERISA Restricted Certificates to the effect that such transferee is not an employee benefit plan subject to Title I of ERISA, a plan subject to Section 4975 of the Code or a plan or arrangement subject to any provisions under any federal, state, local, non-U.S. or other laws or regulations that are substantively similar to the foregoing provisions of ERISA or the Code ("Similar Law") (collectively, a "Plan"), and is not directly or indirectly acquiring the Certificate for, on behalf of or with any assets of any such Plan, or (II) solely in the case of an ERISA Restricted Certificate, (A) if the Certificate has been the subject of an ERISA-Qualifying Underwriting, a 57 representation as set forth in Exhibit M that such transferee is an insurance company that is acquiring the ERISA-Restricted Certificate with assets contained in an "insurance company general account," as defined in Section V(E) of Prohibited Transaction Class Exemption ("PTCE") 95-60, and the acquisition and holding of the Certificate are covered and exempt under Sections I and III of PTCE 95-60, or (B) solely in the case of a Definitive Certificate, an Opinion of Counsel reasonably satisfactory to the Depositor and the Trustee to the effect that the acquisition and holding of such Certificate will not constitute or result in a nonexempt prohibited transaction under ERISA or the Code, or a violation of Similar Law, and will not subject the Depositor, the Servicer or the Trustee to any obligation in addition to those expressly undertaken in this Agreement, which Opinion of Counsel shall not be an expense of the Depositor, the Servicer or the Trustee. (ii) Except in the case of a Definitive Certificate, the representations set forth in paragraph (i) of this Subsection 4.02(d), other than subparagraph (i)(II)(B), shall be deemed to have been made to the Depositor and the Trustee by the transferee's acceptance of an ERISA Restricted Certificate or a Class A-R Certificate (or the acceptance by a Certificate Owner of the beneficial interest in any Class of ERISA Restricted Certificates or a Class A-R Certificate). Notwithstanding any other provision herein to the contrary, any purported transfer of an ERISA Restricted Certificate or a Class A-R Certificate to or on behalf of a Plan without the delivery to the Depositor of a representation or an Opinion of Counsel reasonably satisfactory to the Depositor and the Trustee as described above shall be void and of no effect. None of the Depositor, the Servicer or the Trustee shall be under any liability to any Person for any registration or transfer of any ERISA Restricted Certificate or Class A-R Certificate that is in fact not permitted by this Section 4.02(d) nor shall the Paying Agent be under any liability 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 in accordance with the foregoing requirements. The Depositor, Servicer, Paying Agent and/or Trustee shall be entitled, but not obligated, to recover from any Holder of any ERISA Restricted Certificate or Class A-R Certificate that was in fact a Plan and that held such Certificate in violation of this Section 4.02(d) all payments made on such ERISA Restricted Certificate or Class A-R Certificate at and after the time it commenced such holding. Any such payments so recovered shall be paid and delivered to the last preceding Holder of such Certificate that is not a Plan. (e) At the option of a Certificateholder, a Certificate may be exchanged for another Certificate or Certificates of authorized denominations of a like Class, upon surrender of the Certificate to be exchanged at any office or agency of the Trustee, or if a Paying Agent has been appointed under Section 4.05, the Paying Agent, maintained for such purpose. Whenever the Certificate is so surrendered for exchange, the Depositor shall execute and the Authenticating Agent shall authenticate and deliver, the Certificate which the Certificateholder making the exchange is entitled to receive. Every Certificate presented or surrendered for transfer or exchange shall (if so required by the Authenticating Agent) be duly endorsed by, or be accompanied by a written instrument of transfer in the form satisfactory to the Authenticating Agent duly executed by, the Holder thereof or his attorney duly authorized in writing. (f) No service charge shall be made to the Holder for any transfer or exchange of a Certificate, but the Servicer may require payment by the Certificateholders of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any transfer or exchange of such Certificate. (g) All Certificates surrendered for transfer or exchange shall be destroyed by the Trustee or if a Paying Agent has been appointed under Section 4.05, the Paying Agent, in accordance with the Trustee's or, if a Paying Agent has been appointed under Section 4.05, the Paying Agent's, standard procedures. 58 (h) [Reserved]. (i) A Disqualified Organization is prohibited from acquiring beneficial ownership of a Class A-R Certificate. Notwithstanding anything to the contrary contained herein, (i) unless and until the Servicer and the Trustee shall have received an Opinion of Counsel, satisfactory to it in form and substance, to the effect that the absence of the conditions contained in this Section 4.02(i) would not result in the imposition of federal tax upon any REMIC created hereunder or cause any REMIC created hereunder to fail to qualify as a REMIC, no transfer, sale or other disposition of the Class A-R Certificate (including for purposes of this section any beneficial interest therein) may be made without the express written consent of the Certificate Registrar or, if no Certificate Registrar is appointed, the Trustee, which consent is to be granted by the Certificate Registrar or, if no Certificate Registrar is appointed, the Trustee only upon compliance with the requirements of this Section and (ii) no transfer, sale or other disposition of the Class A-R Certificate (or any beneficial interest therein) may be made to a Person who is not a U.S. Person unless such Person furnishes the transferor, the Certificate Registrar and the Trustee, with a duly completed and effective Form W-8ECI (or any successor thereto) or an Opinion of Counsel to the effect that such transfer is in accordance with the requirements of the Code and that the transfer will not be disregarded for federal income tax purposes. As a condition to granting its consent to a transfer of a Class A-R Certificate, the Certificate Registrar or, if no Certificate Registrar is appointed, the Trustee, shall require the proposed transferee of such Certificate (including, in the case of the initial issuance of the Class A-R Certificate, the initial Holder thereof) to execute a letter and affidavit substantially in the form attached hereto as Exhibit K and shall require the proposed transferor (other than in the case of the transfer to the initial Holder) of such Certificate to execute a letter substantially in the form attached hereto as Exhibit K-1. In the absence of a contrary instruction from the transferor of such Certificate, declaration (11) in the affidavit in Exhibit K may be left blank. If the transferor requests by written notice to the Certificate Registrar or, if no Certificate Registrar is appointed, the Trustee, prior to the date of the proposed transfer that one of the two other forms of declaration (11) of such affidavit be used, then the Certificate Registrar or, if no Certificate Registrar is appointed, the Trustee, shall require that such form of declaration (11) be included in such affidavit. As a condition to the granting of the consent referred to in this Section 4.02(i), prior to the transfer, sale, pledge, hypothecation or other disposition of the Class A-R Certificate or any interest therein, the Certificate Registrar or, if no Certificate Registrar is appointed, the Trustee shall require that (1) the proposed transferee deliver to the Trustee or Certificate Registrar, as applicable, its taxpayer identification number and state, under penalties of perjury that such number is the social security or employer identification number, as the case may be, of the transferee or provide an affidavit under penalties of perjury stating that as of the date of such transfer such transferee is not and has no intention of becoming a Disqualified Organization; (2) the proposed transferee deliver to the Trustee or Certificate Registrar, as applicable, an affidavit stating (i) that such transferee is not acquiring such Class A-R Certificate as an agent, broker, nominee, or middleman for a Disqualified Organization, (ii) if the Class A-R Certificate is a "non-economic residual interest" within the meaning of Treas. Reg. Section 1.860E-1(c)(2), (X) that no purpose of the acquisition of the Class A-R Certificate is to avoid or impede the assessment or collection of tax, (Y) that such transferee has historically paid its debts as they came due and will continue to pay its debts as they come due, and (Z) that such transferee represents that it understands that, as the holder of the non-economic residual interest, the transferee may incur tax liabilities in excess of any cash flows generated by the interest and that the transferee intends to pay taxes associated with holding the residual interest, and (iii) unless the Certificate Registrar or, if no Certificate Registrar is appointed, the Trustee consents to the transfer of the Class A-R Certificate to a Person who is not a U.S. Person and who has furnished either a duly completed and effective Form W-8ECI (or any successor thereto) or an Opinion of Counsel to the effect that the transfer will not be disregarded for federal income tax purposes, that it is a U.S. Person; (3) if so requested by the transferor in written notice provided to the Certificate Registrar or, if no Certificate Registrar is appointed, the Trustee, prior to the date of the proposed transfer, 59 the proposed transferee deliver to the Trustee or Certificate Registrar, as applicable, an affidavit that includes a declaration made in the form of declaration (11) in the affidavit set forth in Exhibit K requested by the transferor; and (4) the transferor deliver to the Certificate Registrar or, if no Certificate Registrar is appointed, the Trustee a written certification that as of the date of such transfer it has no knowledge and no reason to know that the affirmations described in clauses (1), (2) and (3) were false. The Certificate Registrar or, if no Certificate Registrar is appointed, the Trustee shall not grant the consent referred to in this Section 4.02(i) if it has actual knowledge that any statement made in the affidavit issued pursuant to the preceding sentence is not true. Notwithstanding any purported transfer, sale or other disposition of the Class A-R Certificate to a Disqualified Organization or in violation of the provisions of this Section 4.02(i), such transfer, sale or other disposition shall be deemed to be of no legal force or effect whatsoever and such Disqualified Organization shall not be deemed to be a Class A-R Certificateholder for any purpose hereunder, including, but not limited to, the receipt of distributions on such Class A-R Certificate. If any purported transfer shall be in violation of the provisions of this Section 4.02(i) then the prior Holder of the Class A-R Certificate shall, upon discovery that the transfer of such Class A-R Certificate was not in fact permitted by this Section 4.02(i), be restored to all rights and obligations as a Holder thereof retroactive to the date of the purported transfer of such Class A-R Certificate. The Trustee, the Servicer and the Certificate Registrar shall be under no liability to any Person for any registration or transfer of a Class A-R Certificate that is not permitted by this Section 4.02(i) or for making payments due on such Class A-R Certificate to the purported Holder thereof or taking any other action with respect to such purported Holder under the provisions of this Agreement so long as the transfer was not registered under the written certification of the Certificate Registrar or, if no Certificate Registrar is appointed, the Trustee as described in this Section 4.02(i). The prior Holder shall be entitled to recover from any purported Holder of a Class A-R Certificate that was in fact not a permitted purported transferee under this Section 4.02(i) at the time it became a purported Holder all payments made to such purported Holder on such Class A-R Certificate; provided that the Servicer shall not be responsible for such recovery. Each Class A-R Certificateholder, by the acceptance of the Class A-R Certificate, shall be deemed for all purposes to have consented to the provisions of this Section 4.02(i) and to any amendment to this Agreement deemed necessary by counsel of the Trustee or the Servicer to ensure that the Class A-R Certificate is not transferred to a Disqualified Organization and that any transfer of such Class A-R Certificate will not cause the imposition of a tax upon any REMIC created hereunder or cause any REMIC created hereunder to fail to qualify as a REMIC. The restrictions on transfer of the Class A-R Certificate will cease to apply and be void upon receipt by the Certificate Registrar or, if no Certificate Registrar is appointed, the Trustee of an Opinion of Counsel to the effect that such restrictions on transfer are no longer necessary to avoid the risk of material federal taxation to any REMIC created hereunder or prevent any REMIC created hereunder from qualifying as a REMIC. (j) The Servicer shall make available upon written request to each Holder and each proposed transferee of a Class B-3, Class B-4 or Class B-5 Certificate such information as may be required to permit the proposed transfer to be effected pursuant to Rule 144A under the Securities Act. Section 4.03 Mutilated, Destroyed, Lost or Stolen Certificates. If (a) any mutilated Certificate is surrendered to the Trustee or, if a Paying Agent has been appointed under Section 4.05, the Paying Agent, or the Trustee or, if a Paying Agent has been appointed under Section 4.05, the Paying Agent, receives evidence to its satisfaction of the destruction, loss or theft of any Certificate, and (b) there is delivered to the Trustee or, if a Paying Agent has been appointed under Section 4.05, the Paying Agent, such security or indemnity as may be required by it to save it harmless, then, in the absence of notice to the Trustee or, if a Paying Agent has been appointed under Section 4.05, the Paying Agent, that such Certificate has been acquired by a bona fide purchaser, the Trustee or, if a Paying Agent has been appointed under Section 4.05, the Paying Agent, shall authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new Certificate of like tenor and Class. Upon the issuance of any new Certificate under this Section, the Trustee or, if a Paying Agent has been 60 appointed under Section 4.05, the Paying Agent, may require of the Certificateholder 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 connected therewith. Any replacement Certificate of any Class issued pursuant to this Section shall constitute complete and indefeasible evidence of ownership of the Percentage Interest in the distributions to which the Certificateholders of such Class are entitled, as if originally issued, whether or not the mutilated, destroyed, lost or stolen Certificate shall be found at any time, and such mutilated, destroyed, lost or stolen Certificate shall be of no force or effect under this Agreement, to the extent permitted by law. Section 4.04 Persons Deemed Owners. Prior to due presentation of a Certificate of any Class for registration of transfer, the Depositor, the Servicer, the Paying Agent and the Trustee may treat the Person in whose name any Certificate is registered on the Record Date as the owner of such Certificate and the Percentage Interest in the distributions to which the Certificateholders of such Class are entitled on the relevant date as the Holder of such Certificate and the Percentage Interest represented by such Certificate for the purpose of receiving remittances pursuant to Section 6.01 and for all other purposes whatsoever, and neither the Depositor, the Servicer, the Paying Agent nor the Trustee shall be affected by notice to the contrary. Section 4.05 Appointment of Paying Agent and Certificate Registrar; Certificate Account. The Trustee shall appoint a Paying Agent and a Certificate Registrar (the "Certificate Registrar") hereunder, provided such Paying Agent and such Certificate Registrar shall not be the Depositor, any Seller, or an Affiliate of the Depositor or any Seller. No later than two Business Days prior to each Distribution Date, the Servicer shall deposit or cause to be deposited with the Paying Agent from funds on deposit in the Collection Account a sum up to the Available Distribution Amount, such sum to be held in trust for the benefit of Certificateholders in a segregated account (the "Certificate Account") which shall be an Eligible Account in the name of "The Bank of New York Trust Company, N.A., as Trustee, in trust for and for the benefit of the Certificateholders of Multi-Class Mortgage Pass-Through Certificates, Chase Mortgage Finance Corporation, Series 2007-S4 - Certificate Account". The Paying Agent shall establish such Certificate Account with a commercial bank, a savings bank or a savings and loan association. The Paying Agent may invest moneys in the Certificate Account in Eligible Investments, which shall mature not later than a date sufficient to make payment on the Distribution Date next following the date of such investment and shall not be sold or disposed of prior to maturity. All income and gain realized from any such investment shall be for the benefit of the Paying Agent as additional compensation and shall be subject to its withdrawal or order from time to time. The amount of any losses incurred in respect of any such investments (to the extent not offset by income from other such investments) shall be deposited in the Certificate Account by the Paying Agent out of its own funds immediately as realized. The Servicer shall cause the Paying Agent to perform each of the obligations of the Paying Agent set forth herein and shall be liable to the Trustee and the Certificateholders for failure of the Paying Agent to perform such obligations. So long as the Paying Agent is a party other than the Trustee, the Trustee shall have no liability in connection with the performance or failure of performance of the Paying Agent. The Trustee designates The Bank of New York Trust Company, N.A. as the initial Paying Agent and initial Certificate Registrar. Only the Trustee may remove the Paying Agent and Certificate Registrar and may do so at will, provided that the Trustee gives 20 days' prior written notice of such removal to the Paying Agent and Certificate Registrar and the Rating Agencies. The Paying Agent will hold all sums held by it for the payment to Certificateholders in trust for the benefit of the Certificateholders entitled thereto until such sums shall be paid to such Certificateholders. Section 4.06 Authenticating Agents. 61 (a) The Trustee may appoint one or more Authenticating Agents (each, an "Authenticating Agent") which shall be authorized to act on behalf of the Trustee in authenticating the Certificates. Wherever reference is made in this Agreement to the authentication of Certificates by the Trustee or the Trustee's certificate of authentication, such reference shall be deemed to include authentication on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent must be an entity organized and doing business under the laws of the United States of America or of any state, having a combined capital and surplus of at least $15,000,000, authorized under such laws to do a trust business and subject to supervision or examination by federal or state authorities. So long as the Authenticating Agent is a party other than the Trustee, the Trustee shall have no liability in connection with the performance or failure of performance of the Authenticating Agent. The Trustee hereby appoints the Paying Agent as the initial Authenticating Agent. (b) Any Person into which any Authenticating Agent may be merged or converted or with which it may be consolidated, or any Person resulting from any merger, conversion or consolidation to which any Authenticating Agent shall be a party, or any Person succeeding to the corporate agency business of any Authenticating Agent, shall continue to be the Authenticating Agent without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent. (c) Any Authenticating Agent may at any time resign by giving at least 30 days' advance written notice of resignation to the Trustee and the Depositor. The Trustee may at any time terminate the agency of any Authenticating Agent by giving written notice of termination to such Authenticating Agent and the Depositor. Upon receiving a notice of resignation or upon such a termination, or in case at any time any Authenticating Agent shall cease to be eligible in accordance within the provisions of this Section 4.06, the Trustee may appoint a successor Authenticating Agent, shall give written notice of such appointment to the Depositor and shall mail notice of such appointment to all Holders of Certificates. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers, duties and responsibilities of its predecessor hereunder, with like effect as if originally named as Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section 4.06. No Authenticating Agent shall have responsibility or liability for any action taken by it as such at the direction of the Trustee. Each of the Authenticating Agent, Certificate Registrar and Paying Agent shall be afforded the same rights, protections and indemnities as the Trustee as set forth under Article VIII hereunder. [END OF ARTICLE IV] ARTICLE V ADMINISTRATION AND SERVICING OF MORTGAGE LOANS Section 5.01 Servicer to Service Mortgage Loans. The Servicer shall service and administer the Mortgage Loans and shall have full power and authority, acting alone or through Sub-Servicers as provided in Section 5.02, to do any and all things which it may deem necessary or desirable in connection with such servicing and administration, all in accordance with Accepted Servicing Practices. Without limiting the generality of the foregoing, the Servicer in its own name or in the name of a Sub-Servicer shall, pursuant to a power of attorney granted hereby by the Trustee for such purposes, when the Servicer or the Sub-Servicer, as the case may be, believes it appropriate in its best judgment, to execute and deliver, on behalf of the Certificateholders and the Trustee 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 Mortgage Loans and with respect to the related Mortgaged Properties; provided, 62 however, that subject to the provisions of this paragraph, the Servicer may allow a modification with respect to a Mortgage Loan if the Servicer would take such action in the ordinary course of its business if it were the owner of the Mortgage Loan. The Servicer will indemnify the Trustee for any misuse of such power of attorney provided hereunder. The Servicer may agree to a modification of any Mortgage Loan (the "Relevant Mortgage Loan") upon the request of the related Mortgagor, provided that (i) the modification is in lieu of a refinancing and the Mortgage Rate on the Relevant Mortgage Loan, as modified, is approximately a prevailing market rate of newly-originated mortgage loans having similar terms and (ii) the Servicer purchases the Relevant Mortgage Loan from the Trust Fund as described below. Effective immediately after such modification, and, in any event, on the same Business Day on which the modification occurs, all right, title and interest of the Trustee in and to the Modified Mortgage Loan shall automatically be deemed transferred and assigned to the Servicer and all benefits and burdens of ownership thereof, including without limitation the right to accrued interest thereon from and including the date of modification and the risk of default thereon, shall pass to the Servicer. To confirm such transfer and assignment, the Servicer, as servicer hereunder, as soon as practicable shall execute an instrument of assignment of the Modified Mortgage Loan without recourse in customary form to the Servicer in its individual capacity. The Servicer shall deposit the Purchase Price for any Modified Mortgage Loan in the Collection Account pursuant to Section 5.08. Upon receipt by the Trustee of written notification of any such deposit signed by a Servicing Officer, the Trustee shall release to the Servicer the related Mortgage File and shall execute and deliver such instruments of transfer or assignment, in each case without recourse, as shall be necessary more fully to vest in the Servicer any Modified Mortgage Loan previously transferred and assigned pursuant thereto. Notwithstanding anything herein to the contrary, the Servicer shall not make or permit any modification of a Mortgage Loan that would cause any REMIC Pool to fail to qualify as a REMIC for federal income tax purposes or that would result in the imposition of any material tax under Section 860F(a) or Section 860G(d) of the Code. Notwithstanding anything to the contrary contained in this Agreement, the Servicer may also agree to any modification, waiver or amendment of a Mortgage Loan that is in default or with respect to which default is reasonably foreseeable, provided that, in the sole judgment of the Servicer, such modification, waiver or amendment is reasonably designed to produce a greater recovery with respect to the Mortgage Loan on a present value basis than would liquidation of the Mortgage Loan. The Servicer shall furnish to the Trustee for execution and redelivery to the Servicer or, at the request of the Servicer, a Sub-Servicer, such documents necessary or appropriate to enable the Servicer to service and administer the Mortgage Loans and the Trustee shall not be responsible for the Servicer's application thereof. The Servicer agrees to remain eligible as either a FNMA or FHLMC seller/servicer, or both, for so long as it is Servicer. All Servicing Advances made by the Servicer in effecting the timely payment of taxes, insurance and assessments on the properties subject to the Mortgage Loans shall not, for the purpose of calculating monthly distributions to Certificateholders, be added to the amount owing under the related Mortgage Loans, notwithstanding that the terms of such Mortgage Loan so permit, and such Servicing Advances shall be recoverable by the Servicer to the extent permitted by Sections 5.09 and 5.23. Section 5.02 Sub-Servicing Agreements Between Servicer and Sub-Servicers; Enforcement of Sub-Servicer's Obligations. (a) The Servicer may enter into Sub-Servicing Agreements with Sub-Servicers for the servicing and administration of all or part of the Mortgage Loans. References in this Agreement to actions taken or to be taken by the Servicer in servicing the Mortgage Loans serviced by it include actions taken or to be taken by a Sub-Servicer on behalf of the Servicer. Each Sub-Servicing Agreement will be upon such terms and conditions as are not inconsistent with this Agreement and as the Servicer 63 and the Sub-Servicer have agreed. The Servicer hereby agrees to notify the Trustee in writing promptly upon the appointment of any Sub-Servicer. For purposes of this Agreement, the receipt by the Sub-Servicer of any amount with respect to a Mortgage Loan (other than amounts representing servicing compensation or reimbursement for an advance) shall be treated as the receipt by the Servicer of such amount. The Sub-Servicer shall deposit all such funds in an Eligible Account. (b) As part of its servicing activities hereunder, the Servicer, for the benefit of the Trustee and the Certificateholders, shall enforce the obligations of each Sub-Servicer under the related Sub-Servicing Agreement. Such enforcement, including, without limitation, the legal prosecution of claims, termination of Sub-Servicing Agreements as appropriate, and the pursuit of other remedies, shall be in such form and carried out to such an extent and at such time as the Servicer, in its good faith business judgment, would require were it the owner of the related Mortgage Loans. The Servicer shall pay the costs of such enforcement at its own expense but shall be reimbursed therefor only (i) from a general recovery resulting from such enforcement only to the extent, if any, that such recovery exceeds all amounts due in respect of the related Mortgage Loans or (ii) from a specific recovery of costs, expenses or attorneys' fees against the party against whom such enforcement is directed. (c) The Servicer shall not permit a Sub-Servicer to perform any servicing responsibilities hereunder with respect to the Mortgage Loans unless that Sub-Servicer first agrees in writing with the Servicer to deliver an Assessment of Compliance and an Accountant's Attestation in such manner and at such times that permits the Servicer to comply with Section 5.25 of this Agreement. Section 5.03 Successor Sub-Servicers. The Servicer shall be entitled to terminate any Sub-Servicing Agreement that may exist in accordance with the terms and conditions of such Sub-Servicing Agreement and without any limitation by virtue of this Agreement. Section 5.04 Liability of the Servicer. Notwithstanding any Sub-Servicing Agreement, any of the provisions of this Agreement relating to agreements or arrangements between the Servicer and a Sub-Servicer or reference to actions taken through a Sub-Servicer or otherwise, the Servicer shall remain obligated and liable to the Trustee and Certificateholders for the servicing and administering of the Mortgage Loans in accordance with the provisions of this Agreement without diminution of such obligation or liability by virtue of such Sub-Servicing Agreements or arrangements or by virtue of indemnification from the Sub-Servicer and to the same extent and under the same terms and conditions as if the Servicer alone were servicing and administering the Mortgage Loans. The Servicer shall be entitled to enter into any agreement with a Sub-Servicer for indemnification of the Servicer and nothing contained in this Agreement shall be deemed to limit or modify such indemnification. Section 5.05 No Contractual Relationship Between Sub-Servicer and Trustee or Certificateholders. Any Sub-Servicing Agreement that may be entered into and any other transactions or services relating to the Mortgage Loans involving a Sub-Servicer in its capacity as such and not as an originator shall be deemed to be between the Sub-Servicer and the Servicer alone, and the Trustee and Certificateholders shall not be deemed parties thereto and shall have no claims, rights, obligations, duties or liabilities with respect to the Sub-Servicer. Section 5.06 Termination of Sub-Servicing Agreement. If the Servicer shall for any reason no longer be the Servicer hereunder (including by reason of any Event of Default), the Servicer shall thereupon terminate each Sub-Servicing Agreement that may have been entered into, and the Trustee, its designee or the successor servicer and the Trustee shall not be deemed to have assumed any of the Servicer's interest therein or to have replaced the Servicer as a party to any such Sub-Servicing Agreement. 64 Section 5.07 Collection of Mortgage Loan Payments. Continuously from the date hereof until the principal and interest on all Mortgage Loans are paid in full, the Servicer will proceed diligently to collect all payments due under each of the Mortgage Loans when the same shall become due and payable; provided, however, that the Servicer may elect, to the extent consistent with Accepted Servicing Practices, to waive any late payment charge and shall, to the extent such procedures shall be consistent with this Agreement, follow such collection procedures as it follows with respect to conventional mortgage loans held in its own portfolio. Any such arrangements shall not diminish or otherwise affect the Servicer's obligation to make Advances pursuant to Section 6.03. Section 5.08 Establishment of Collection Account; Deposit in Collection Account. With respect to all of the Mortgage Loans, the Servicer shall segregate and hold all funds collected and received pursuant to a Mortgage Loan separate and apart from any of its own funds and general assets and shall establish and maintain one or more Collection Accounts for the benefit of the Certificateholders (collectively, the "Collection Account") which are Eligible Accounts, in the form of a trust account, in the name of "The Bank of New York Trust Company, N.A., as Trustee, in trust for and for the benefit of the Certificateholders of Multi-Class Mortgage Pass-Through Certificates, Chase Home Finance LLC as subservicer for JPMorgan Chase Bank, N.A. as Servicer, Chase Mortgage Finance Corporation, Series 2007-S4 - Collection Account." Such Collection Account shall be established with a commercial bank, a savings bank or a savings and loan association. The Servicer may invest, or cause the institution maintaining the Collection Account to invest, moneys in the Collection Account in Eligible Investments, which shall mature not later than two Business Days preceding the Distribution Date next following the date of such investment and shall not be sold or disposed of prior to its maturity. All income and gain realized from any such investment shall be for the benefit of the Servicer as additional compensation and shall be subject to its withdrawal or order from time to time. The amount of any losses incurred in respect of any such investments (to the extent not offset by income from other such investments) shall be deposited in the Collection Account by the Servicer out of its own funds immediately as realized; provided, however, that if the Trustee becomes the Servicer, the Trustee shall not be required to deposit the amount of any loss incurred prior to it becoming the Servicer. The Servicer shall deposit or cause to be deposited in the Collection Account on a daily basis (and not later than the second Business Day following receipt), and retain therein: (i) All payments which were received after the Cut-off Date on account of principal of the Mortgage Loans (other than the principal portion of Monthly Payments due on or before the Cut-off Date), and all Principal Prepayments collected on or after the Cut-off Date; (ii) All payments which were received after the Cut-off Date on account of interest on the Mortgage Loans (net of the Servicing Fee)(other than the interest portion of Monthly Payments due on or before the Cut-off Date); (iii) Any Subsequent Recovery or Net Liquidation Proceeds; (iv) All Insurance Proceeds received by the Servicer under any title, hazard or other insurance policy, including amounts required to be deposited pursuant to Sections 5.16 and 5.20, other than proceeds to be held in the Escrow Account or applied to the restoration or repair of the Mortgaged Property (or Underlying Mortgaged Property, in the case of a Co-op Loan) or released to the Mortgagor in accordance with the Servicer's normal servicing procedures or otherwise applied or held as required by applicable law; 65 (v) All awards or settlements in respect of condemnation proceedings affecting any Mortgaged Property (or Underlying Mortgaged Property, in the case of a Co-op Loan), which are not released to the Mortgagor in accordance with the Servicer's normal servicing procedures; (vi) All Repurchase Proceeds; (vii) All Advances made by the Servicer pursuant to Section 6.03; (viii) All amounts representing revenues under the insurance provided pursuant to Section 5.19 to the extent of any losses borne by any Certificateholder; (ix) All revenues from any Mortgaged Property (or Underlying Mortgaged Property in the case of a Co-op Loan) acquired by the Servicer by foreclosure or deed in lieu of foreclosure net of any Servicing Advances with respect to such Mortgaged Property (or Underlying Mortgaged Property in the case of a Co-op Loan); and (x) Any other amounts required to be deposited therein pursuant to this Agreement. The Servicer shall maintain accounting records on a Mortgage Loan by Mortgage Loan basis with respect to the Collection Account. The Servicer shall give notice to the Trustee, any Paying Agent, the Depositor and each Rating Agency of any change in the location of the Collection Account, prior to the use thereof. Notwithstanding anything to the contrary herein, no Monthly Payment or any portion thereof shall be permitted to remain in the Collection Account for more than 12 months. Any Monthly Payment or any portion thereof that has remained in the Collection Account for 12 months shall be deemed a Principal Prepayment and distributed to Certificateholders pursuant to the provisions of this Agreement on the Distribution Date immediately following the end of such 12 month period. Section 5.09 Permitted Withdrawals from the Collection Account. The Servicer may, from time to time, withdraw funds from the Collection Account for the following purposes: (a) to reimburse itself for Advances made pursuant to Section 6.03 (including amounts to reimburse the related Sub-Servicer for advances made pursuant to the applicable Sub-Servicing Agreement), the Servicer's and the related Sub-Servicer's right to receive reimbursement pursuant to this subclause (i) being limited to amounts received on particular Mortgage Loans which represent Late Collections (net of the Servicing Fees) with respect to those particular Mortgage Loans; (b) to pay itself the Servicing Fee; (c) to reimburse itself for unreimbursed Servicing Advances, or to pay the related Sub-Servicer any unreimbursed Servicing Advances, the Servicer's right to receive reimbursement or make payments to the Sub-Servicer pursuant to this subclause (c) with respect to any Mortgage Loan being limited to related Liquidation Proceeds, Insurance Proceeds, Subsequent Recoveries and condemnation awards; (d) to reimburse itself (or the related Sub-Servicer) or the Depositor for expenses incurred by and recoverable by or reimbursable to it pursuant to Section 5.01 or 5.16; (e) to reimburse itself (or the related Sub-Servicer) for any Nonrecoverable Advances; (f) to pay to itself (or the related Sub-Servicer) income earned on the investment of funds deposited in the Collection Account; 66 (g) to make deposits into the Certificate Account in the amounts and in the manner provided for herein; (h) to make payments to itself or others pursuant to any provision of this Agreement, and to clear and terminate the Collection Account upon the termination of this Agreement; and (i) to withdraw amounts deposited in error. Section 5.10 Establishment of Escrow Account; Deposits in Escrow Account. With respect to those Mortgage Loans on which the Servicer or any Sub-Servicer collects Escrow Payments, if any, the Servicer shall, and shall cause any Sub-Servicer to, segregate and hold all funds collected and received pursuant to each such Mortgage Loan which constitute Escrow Payments separate and apart from any of its own funds and general assets and shall establish and maintain one or more Escrow Accounts, in the form of trust accounts. Such Escrow Accounts shall be established with a commercial bank, a mutual savings bank or a savings and loan association the deposits of which are insured by the FDIC in a manner which shall provide maximum available insurance thereunder, and which may be drawn on by the Servicer. The Servicer shall, if requested by the Trustee, give notice to the Trustee of the location of any Escrow Account. Nothing in this paragraph shall be deemed to require the Servicer to collect Escrow Payments in the absence of a provision in the related Mortgage requiring such collection. The Servicer shall deposit, or cause to be deposited, in any Escrow Account or Accounts on a daily basis, and retain therein, (i) all Escrow Payments collected on account of any Mortgage Loans serviced by the Servicer, for the purpose of effecting timely payment of any such items as required under the terms of this Agreement and (ii) all amounts representing proceeds of any hazard insurance policy which are to be applied to the restoration or repair of any Mortgaged Property (or Underlying Mortgaged Property, in the case of a Co-op Loan). The Servicer shall make withdrawals therefrom only to effect such payments as are required under this Agreement, and for such other purposes as are set forth in Section 5.11. The Servicer shall be entitled to retain any interest paid on funds deposited in the Escrow Account by the depository institution other than interest on escrowed funds required by law to be paid to the related Mortgagor and, to the extent required by law, the Servicer shall pay interest on escrowed funds to the related Mortgagor notwithstanding that the Escrow Account is non-interest-bearing or that interest paid thereon is insufficient for such purposes. Section 5.11 Permitted Withdrawals from Escrow Account. Withdrawals from any Escrow Account or Accounts may be made by a Servicer only (i) to effect timely payments of ground rents, taxes, assessments, water rates, Standard Hazard Policy premiums, or other items constituting Escrow Payments for the related Mortgage, (ii) to reimburse the Servicer for any Servicing Advance made by the Servicer, with respect to a related Mortgage Loan but only from amounts received on the related Mortgage Loan which represent late payments or collections of Escrow Payments thereunder, (iii) to refund to any Mortgagor any funds found to be in excess of the amounts required under the terms of the related Mortgage Loan or under applicable law, (iv) for application to restoration or repair of the property subject to the related Mortgage, (v) to pay to the Servicer, or to the Mortgagor to the extent required by law, any interest paid on the funds deposited in the Escrow Account, (vi) to clear and terminate the Escrow Account on the termination of this Agreement or (vii) to withdraw amounts deposited in error. Section 5.12 Payment of Taxes, Insurance and Other Charges. With respect to each Mortgage Loan, the Servicer shall maintain, or cause to be maintained, accurate records reflecting any delinquencies or nonpayments with regard to taxes, assessments and Standard Hazard Policy premiums. The Servicer assumes full responsibility for ensuring the payment of all such bills and shall effect payments of all such bills irrespective of each Mortgagor's faithful performance in the payment of same or the making of the Escrow Payments and shall make advances from its own funds to effect such payments. 67 Section 5.13 Transfer of Accounts. The Servicer may transfer the Collection Account or Escrow Account to an Eligible Account maintained with a different depository institution from time to time and shall notify the Trustee and the Paying Agent of any such transfer. Section 5.14 [Reserved]. Section 5.15 Maintenance of the Primary Insurance Policies. The Servicer shall not take, or permit any related Sub-Servicer to take, any action which would result in non-coverage under any applicable Primary Insurance Policy of any loss which, but for the actions of the Servicer or Sub-Servicer, would have been covered thereunder. Except as otherwise required by applicable law, to the extent coverage is available and until the Loan-to-Value Ratio of the related Mortgage Loan is reduced to 80%, the Servicer shall keep or cause to be kept in full force and effect each such Primary Insurance Policy in an amount equal to the amount by which the unpaid principal balance of the related Mortgage Loan exceeds 75% of the value (as described in the definition of Loan-to-Value Ratio) of the related Mortgaged Property (or Underlying Mortgaged Property, in the case of a Co-op Loan). The Servicer shall not cancel or refuse to renew any such Primary Insurance Policy or consent to any related Sub-Servicer canceling or refusing to renew any such Primary Insurance Policy applicable to a Mortgage Loan subserviced by it, that is in effect at the date of the initial issuance of the Certificates and is required to be kept in force hereunder unless the replacement Primary Insurance Policy for such canceled or non-renewed policy is maintained with an insurer whose claims-paying ability is rated at least as high as the original insurer or is acceptable to each Rating Agency as confirmed in writing by each such Rating Agency, unless otherwise required by law. Section 5.16 Maintenance of Standard Hazard Policies. (a) The Servicer shall cause to be maintained for each Mortgage Loan (other than a Co-op Loan) a Standard Hazard Policy with extended coverage as is prudent in the area where the Mortgaged Property is located in an amount which is equal to the greater of (i) the lesser of (A) 100% of the maximum insurable value of the improvements securing such Mortgage Loan or (B) the principal balance owing on such Mortgage Loan, or (ii) such amount required to prevent the Mortgagor or mortgagee from becoming a co-insurer. If the Mortgaged Property is in an area identified at the time of origination in the Federal Register by the Federal Emergency Management Agency as having special flood hazards (and such flood insurance has been made available) the Servicer will cause to be maintained a flood insurance policy meeting the requirements of the current guidelines of the Federal Insurance Administration with a generally acceptable insurance carrier, in an amount representing coverage not less than the least of (i) the outstanding Principal Balance of the Mortgage Loan, (ii) the full insurable value or (iii) the maximum amount of insurance which is available under the Flood Disaster Protection Act of 1973, as amended. The Servicer shall also maintain on property acquired upon foreclosure, or by deed in lieu of foreclosure, of any Mortgage Loan, fire and hazard insurance with extended coverage in an amount which is not less than the lesser of (i) the outstanding Principal Balance of the Mortgage Loan or (ii) the maximum insurable value of the improvements which are a part of such property, liability insurance, and, to the extent available, flood insurance in an amount as provided above. Any amounts collected by the Servicer under any such policies (other than amounts to be applied to the restoration or repair of the property subject to the related Mortgage or property acquired in liquidation of the Mortgage Loan, or released to the Mortgagor in accordance with the Servicer's normal servicing procedures) shall be deposited, subject to applicable law, in the Collection Account. It is understood and agreed that no earthquake or other additional insurance need be required by the Servicer of any Mortgagor or maintained on property acquired in respect of a Mortgage Loan, other than pursuant to such applicable laws and regulations as shall at any time be in force and as shall require such additional insurance. All such Standard Hazard Policies and other policies shall be endorsed with standard mortgagee clauses with loss payable to the Servicer or its designee. Any such Standard Hazard Policies or other policies may be in the form of 68 blanket policies; provided, however, that in the event of any claim arising in connection with a hazard loss the Servicer shall be obligated, in the case of blanket insurance policies, to deposit in the Collection Account any amount not payable under such blanket policy because of a deductible clause in such policy and not otherwise payable under an individual policy. The Servicer shall not interfere with the Mortgagor's freedom of choice in selecting either his insurance carrier or agent; provided, however, that the Servicer shall not accept any such insurance policies from insurance companies unless such companies are acceptable insurers in the discretion of the Servicer. (b) Any cost incurred by the Servicer in maintaining any of the foregoing insurance shall not, for the purpose of calculating monthly distributions to Certificateholders, be added to the amount owing under the Mortgage Loan, notwithstanding that the terms of the Mortgage Loan so permit. Such costs (other than the costs of maintaining a blanket hazard insurance policy not attributable to a specific Mortgaged Property) shall be recoverable by the Servicer from the Mortgagor or out of Insurance Proceeds, Subsequent Recoveries or Liquidation Proceeds or to the extent permitted by Section 5.09. Section 5.17 [Reserved]. Section 5.18 [Reserved]. Section 5.19 Fidelity Bond and Errors and Omissions Insurance. The 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 on behalf of the Servicer in any capacity with regard to the Mortgage Loans to handle funds, money, documents and papers relating to the Mortgage Loans. Any such fidelity bond and errors and omissions insurance shall protect and insure the Servicer against losses, including forgery, theft, embezzlement, fraud, errors and omissions and negligent acts of such persons and shall be maintained at a level acceptable to FNMA. No provision of this Section 5.19 requiring such fidelity bond and errors and omissions insurance shall diminish or relieve the Servicer from its duties and obligations as set forth in this Agreement. Upon request of the Trustee, the Servicer shall cause to be delivered to the Trustee a certification evidencing coverage under such fidelity bond and insurance policy. Promptly upon receipt of any notice from the surety or the insurer that such fidelity bond or insurance policy has been terminated or modified in a materially adverse manner, the Servicer shall notify the Trustee and each Rating Agency of any such termination or modification. Section 5.20 Collections under Insurance Policies; Enforcement of Due-On-Sale Clauses; Assumption Agreements. (a) In connection with its activities as administrator and servicer of the Mortgage Loans, the Servicer agrees to present, on behalf of itself, the Trustee and the Certificateholders, claims to the insurer under any Standard Hazard Policies and, in this regard, to take such reasonable action as shall be necessary to permit recovery under any insurance policies. Pursuant to Section 5.08, the Servicer shall deposit Insurance Proceeds in the Collection Account. (b) When any Mortgaged Property (or stock allocated to a dwelling unit, in the case of a Co-op Loan) is conveyed by the Mortgagor, the Servicer shall enforce any due-on-sale clause contained in any Mortgage Note or Mortgage, to the extent permitted by such Mortgage Note or Mortgage, applicable law and governmental regulations. Subject to the foregoing, the Servicer is authorized to take or enter into an assumption or substitution agreement from or with the Person to whom such property has been or is about to be conveyed. In connection with such assumption or substitution, the Servicer shall apply such underwriting standards and follow such practices and procedures as shall be normal and usual and as it applies to mortgage loans owned solely by it. 69 Notwithstanding the foregoing paragraph or any other provision of this Agreement, the Servicer shall not be deemed to be in default, breach or any other violation of its obligations hereunder by reason of any conveyance by the Mortgagor of the Mortgaged Property (or stock allocated to a dwelling unit, in the case of a Co-op Loan) or any assumption of a Mortgage Loan by operation of law which the Servicer in good faith determines it may be restricted by law from preventing, for any reason whatsoever. (c) Subject to the Servicer's duty to enforce any due-on-sale clause to the effect set forth in Section 5.20(b), in any case in which a Mortgaged Property (or stock allocated to a dwelling unit, in the case of a Co-op Loan) is to be 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, the Servicer shall so notify the Trustee by forwarding to the Trustee the original copy of such assumption or substitution agreement, which copy shall be added by the Trustee 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. In connection with any such assumption, modification agreement or substitution agreement, the interest rate of the related Mortgage Note shall not be changed, the principal amount of the Mortgage Note shall not be increased or decreased and the maturity of the Mortgage Note shall not be extended, nor shall it be shortened by more than one year. Any fee collected by the Servicer for entering into an assumption or substitution of liability agreement with respect to such Mortgage Loan shall be retained by the Servicer as additional servicing compensation. Section 5.21 Income and Realization from Defaulted Mortgage Loans. The Servicer, on behalf of the Trustee, shall foreclose upon or otherwise comparably convert the ownership of Mortgaged Properties (or stock allocated to a dwelling unit, in the case of a Co-op Loan) securing such of the Mortgage Loans as come into and continue in default and as to which no satisfactory arrangements can be made for collection of delinquent payments pursuant to Section 5.07, shall manage, conserve, protect and operate such Mortgaged Properties (or stock allocated to a dwelling unit, in the case of a Co-op Loan) for the purposes of their prompt disposition and sale, and shall dispose of such Mortgaged Properties (or stock allocated to a dwelling unit, in the case of a Co-op Loan) on such terms and conditions as it deems in the best interests of the Certificateholders. The Servicer shall sell such property prior to the close of the third calendar year beginning after the year in which such foreclosure or conversion occurs or such longer period as would not prevent such Mortgaged Property (or stock allocated to a dwelling unit, in the case of a Co-op Loan) from constituting "foreclosure property" within the meaning of Section 860G(a)(8) of the Code. The Servicer will ensure that no Mortgaged Property shall be held, rented or otherwise used in such a manner or pursuant to any terms that would (i) cause such Mortgaged Property to fail to qualify as "foreclosure property" within the meaning of Section 860G(a)(8) of the Code or (ii) subject any REMIC Pool to the imposition of any federal income taxes on the income earned on such Mortgaged Property, including any taxes imposed by reason of Section 860F or 860G(c) of the Code. In connection with such activities, the Servicer shall follow such practices and procedures as it shall deem necessary or advisable, as shall be normal and usual in its general mortgage servicing activities, including its management of foreclosed properties for a temporary period as contemplated herein. The foregoing is subject to the provisions of Section 5.28 of this Agreement and to the proviso that the Servicer shall not be required to expend its own funds in connection with any management, foreclosure or towards the restoration of any property unless it shall determine that such management, restoration or foreclosure will increase any Subsequent Recoveries or Liquidation Proceeds of the Mortgage Loan to Certificateholders after reimbursement to itself for such expenses (respecting which it shall have priority for purposes of withdrawals from the Collection Account pursuant to Section 5.09). The Servicer shall be permitted to earn income with respect to any Mortgaged Properties (or stock allocated to a dwelling unit, in the case of a Co-op Loan), provided such income does not constitute "net income from foreclosure property" within the meaning of Section 860G(c) of the Code. The income earned from the management of such Mortgaged Properties (or stock allocated to a dwelling unit, in the case of a Co-op Loan), net of reimbursement to the Servicer for expenses (including any taxes) incurred in connection with such 70 management, shall be applied to the payment of principal of and interest on the related defaulted Mortgage Loans (with interest accruing and principal amortizing as though such Mortgage Loans were still current) and all such income shall be deemed, for all purposes in this Agreement, to be payments on account of principal and interest on the related Mortgage Notes and shall be deposited into the Collection Account. To the extent the income received is in excess of the amount attributable to amortizing principal and accrued interest at the Net Mortgage Rate on the related Mortgage Loan, such excess shall be deposited in the Collection Account. The Servicer shall take into account the existence of any hazardous substances, hazardous wastes or solid wastes, as such terms are defined in the Comprehensive Environmental Response Compensation and Liability Act, as amended, the Resources Conservation and Recovery Act of 1976, as amended, or other federal, state or local environmental legislation, on a Mortgaged Property (or Underlying Mortgaged Property, in the case of a Co-op Loan) in determining whether to foreclose upon or otherwise comparably convert the ownership of such property. To the extent that the Servicer has actual knowledge of any such substance or waste, it shall consult with the Trustee regarding the appropriate course of action. The Servicer shall not institute foreclosure actions with respect to a property containing substance or waste as described above if it reasonably believes that such action would not be consistent with its servicing standards, and in no event shall the Servicer manage, operate or take any other action with respect thereto which the Servicer in good faith believes will result in "clean-up" or other liability under applicable law. The net income from the rental or sale of a REO Property shall be deposited in the Collection Account within two (2) Business Days after receipt thereof by the Servicer. The Servicer may enter into a special servicing agreement with an unaffiliated holder of 100% Percentage Interest of the Class of Class B Certificates then outstanding having the highest numerical class designation or a holder of a class of securities representing interests in such Class B Certificate and/or other subordinate mortgage pass-through certificates, such agreement to be (i) substantially in the form of Exhibit J hereto or (ii) subject to each Rating Agency's acknowledgment that the ratings of the Certificates in effect immediately prior to the entering into of such agreement would not be qualified, downgraded or withdrawn and the Certificates would not be placed on credit review status (except for possible upgrading) as a result of such agreement. Any such agreement may contain provisions whereby such holder may instruct the Servicer to commence or delay foreclosure proceedings with respect to delinquent Mortgage Loans and will contain provisions for the deposit of cash by the holder that would be available for distribution to Certificateholders if Liquidation Proceeds are less than they otherwise may have been had the Servicer acted in accordance with its normal procedures. Section 5.22 Trustee to Cooperate; Release of Mortgage Files. (a) Upon becoming aware of the payment in full of any Mortgage Loan, or upon the receipt by the Servicer of a notification that payment in full will be made in a manner customary for such purposes, the Servicer shall immediately notify the Custodian with a copy to the Trustee by a certification (which certification shall include a statement to the effect that all amounts received or to be received in connection with such payment which are required to be deposited in the Collection Account pursuant to Section 5.08 have been or will be so deposited) of a Servicing Officer and shall request delivery to it of the Mortgage File. Upon receipt of such certification and request, within five Business Days the Custodian on behalf of the Trustee shall release the related Mortgage File to the Servicer and the Trustee will execute and deliver to the Servicer the request for reconveyance, deed of reconveyance or release or satisfaction of mortgage or such other instruments releasing the lien of the Mortgage as have been provided by the Servicer to the Trustee, together with the Mortgage Note with written evidence of cancellation thereon, and the Trustee shall have no further responsibility with respect to said Mortgage File. Upon any such payment in full, or the receipt of such notification, the Servicer is authorized to procure from the Trustee under the deed of trust which secured the Mortgage Note, if any, a deed of full 71 reconveyance covering the property encumbered by such deed of trust, which assignment of deed of trust, except as otherwise provided by any applicable law, shall be recorded by the Servicer in the appropriate land records in the jurisdiction in which the assignment of deed of trust is recorded, or, as the case may be, to procure from the Trustee an instrument of satisfaction or, if the Mortgagor so requests, an assignment without recourse, which deed of reconveyance, instrument of satisfaction or assignment shall be delivered by the Servicer to the Person or Persons entitled thereto. No expenses incurred in connection with any instrument of satisfaction or deed of reconveyance shall be chargeable to the Collection Account or to the Trustee. (b) From time to time as is appropriate for the servicing or foreclosure of any Mortgage Loan, the Servicer shall deliver to the Custodian a certificate of a Servicing Officer requesting that possession of the Mortgage File be released to the Servicer and certifying as to the reason for such release and that such release will not invalidate any insurance coverage provided in respect of the Mortgage Loan under any of the insurance policies required by this Agreement. With such certificate, the Servicer shall require that the Custodian on behalf of the Trustee release the Mortgage File, and, within five Business Days, the Custodian shall deliver the Mortgage File or any document therein to the Servicer. The Servicer shall cause each Mortgage File so released to be returned to the Custodian on behalf of the Trustee when the need therefor by the Servicer no longer exists, unless (i) the Mortgage Loan has been liquidated and the Net Liquidation Proceeds relating to the Mortgage Loan have been deposited in the Collection Account or (ii) the Mortgage File has been delivered to an attorney, or to a public trustee or other public official as required by law, for purposes of initiating or pursuing legal action or other proceedings for the foreclosure of the Mortgaged Property (or stock allocated to a dwelling unit, in the case of a Co-op Loan) either judicially or non-judicially, and the Servicer has delivered to the Custodian on behalf of the Trustee a certificate of a Servicing Officer in the form of Exhibit L hereto certifying as to the name and address of the Person to which such Mortgage File was delivered and the purpose or purposes of such delivery. (c) Upon written request of the Servicer, the Trustee shall execute and deliver to the Servicer any court pleadings, requests for trustee's sale or other documents prepared by and delivered by the Servicer to the Trustee necessary to the foreclosure or trustee's sale in respect of a Mortgaged Property (or stock allocated to a dwelling unit, in the case of a Co-op Loan) or to any legal action brought to obtain judgment against any Mortgagor on the Mortgage Note or Mortgage or to obtain a deficiency judgment, or to enforce any other remedies or rights provided by the Mortgage Note or Mortgage or otherwise available at law or in equity. Together with such documents or pleadings, the Servicer shall deliver to the Trustee a certificate of a Servicing Officer requesting that such pleadings or documents be executed by the Trustee and certifying as to the reason such documents or pleadings are required and that the execution and delivery thereof by the Trustee will not invalidate any insurance coverage under the insurance policies required under this Agreement or invalidate or otherwise affect the lien of the Mortgage, except for the termination of such a lien upon completion of the foreclosure or trustee's sale. The Trustee may rely on such certificate without further inquiry. (d) The Servicer may provide an electronic transmission for release of documents under this Section 5.22 in a form agreed to in advance of initial transmission by both the Servicer and the Custodian, which form shall contain information readable without intervention by Custodian's data processing operations computer hardware and software staff, and arranged in a record layout to be specified by Custodian (a "Paperless Release Request"). The Servicer agrees to maintain and control access to electronic signature information and assumes liability for any unauthorized use thereof, except for any unauthorized use thereof by the Custodian and, provided that, the Servicer shall have no liability arising from the form of transmission if the Servicer complies with the Custodian's standards set forth in the next paragraph of this Section 5.22(d). The Servicer also agrees to maintain accurate records of electronic transactions related to the custodial files. The Servicer hereby authorizes the Custodian to automatically 72 append the electronic signature of an authorized representative to the applicable request for release of documents and agrees and acknowledges that by appending such authorized representative's electronic signature, the Custodian shall be entitled to rely thereon. For purposes of this Agreement the term "electronic signature" means an electronic identifier intended by the person using it to have the same force and effect as the use of a manual signature. The Servicer agrees in advance to comply with all Custodian data encryption, security and record layout standards in connection with any Paperless Release Request as may be amended from time to time upon notice from Custodian to the Servicer. The Custodian reserves the right to restrict or suspend the Servicer's access to the Custodian's computer systems for maintenance or repairs or for any other reason in the Custodian's sole discretion, provided however that the Custodian shall promptly provide the Servicer with notice of such restriction or suspension. Notwithstanding the foregoing, the Servicer is authorized to transmit and the Custodian is authorized to accept signed facsimile copies of the requests for document release described in this Section 5.22. Section 5.23 Servicing and Other Compensation. The Servicer, as compensation for its activities hereunder, shall be entitled to receive, on or prior to each Distribution Date, the amounts provided for as the Servicing Fee and as reimbursement for Nonrecoverable Advances, Servicing Advances and reimbursement for Advances, all as specified by Section 5.09. The amount of compensation or reimbursement provided for shall be accounted for on a Mortgage Loan-by-Mortgage Loan basis. Additional servicing compensation in the form of assumption fees, prepayment fees and late payment charges shall be retained by the Servicer, to the extent permitted by applicable law. The Servicer shall be required to pay all expenses incurred by it in connection with its servicing activities hereunder (including the fees, expenses and indemnities of the Trustee and any Sub-Servicer) and shall not be entitled to reimbursement therefor except as specifically provided in Sections 5.09 and 5.21. Section 5.24 1934 Act Reports. (a) As set forth on Schedule X hereto, for so long as the Trust is subject to the Exchange Act reporting requirements, no later than the end of business on the 2nd Business Day after the occurrence of an event requiring disclosure on Form 8-K (a "reportable event") (i) the Depositor, the Seller, the Trustee and the Paying Agent shall notify the Servicer of any item reportable on a Form 8-K of which each such party has knowledge (unless such item is specific to the Servicer, in which case the Servicer will be deemed to have notice) and (ii) shall deliver to the Servicer at least two Business Days prior to the filing deadline for such Form 8-K, all information, data, and exhibits (unless such information, data, and exhibits are specific to the Servicer) required to be provided or filed with such Form 8-K.

Section 5.28 REMIC-Related Covenants. For as long as the Trust Fund shall exist, the Servicer, the Paying Agent and the Trustee shall act in accordance herewith to assure continuing treatment of each REMIC created hereunder as a REMIC. In particular: (a) The Servicer shall not create, or permit the creation of, any "interests" in any REMIC created hereunder within the meaning of Section 860G(a) of the Code other than the "regular interests" in 77 each such REMIC designated as such in Section 2.04(a) and the "residual interest" in each such REMIC designated as such in Section 2.04(a); (b) As of all times as may be required by the Code, the Servicer will ensure that substantially all of the assets of each REMIC created hereunder will consist of "qualified mortgages" as defined in Section 860G(a)(3) of the Code and "permitted investments" as defined in Section 860G(a)(5) of the Code. The Paying Agent will maintain records that are sufficient to indicate the compliance of each REMIC created hereunder with applicable requirements of the Code (and applicable Proposed, Temporary or final Treasury Regulations) relating to the assets held by such REMIC. Further, the Servicer shall not permit and the Trustee shall not accept the transfer or substitution of any Mortgage Loan other than pursuant to Section 3.03, 5.01 or 5.21 of this Agreement, and the Servicer shall, in any case, not permit substitution unless the Servicer and the Trustee have received an Opinion of Counsel, which will not be an expense of any REMIC created hereunder, that such transfer or substitution would not adversely affect the REMIC status of any REMIC created hereunder or would not otherwise be prohibited by this Agreement; (c) The Servicer shall ensure that no REMIC created hereunder receives a fee or other compensation for services and that no REMIC created hereunder receives any income from assets other than "qualified mortgages" within the meaning of Section 860G(a)(3) of the Code or "permitted investments" within the meaning of Section 860G(a)(5) of the Code, and shall take whatever action it deems necessary to avoid any material tax imposed by the Code on any REMIC created hereunder; (d) None of the Depositor, the Servicer, the Paying Agent or the Trustee shall sell or permit the sale of all or any portion of the Mortgage Loans or of any Eligible Investment unless such sale is as a result of a repurchase of the Mortgage Loans pursuant to this Agreement or the Trustee has received an Opinion of Counsel, which will not be an expense of any REMIC created hereunder or the Trustee, to the effect that such sale (i) is pursuant to a "qualified liquidation" as defined in Section 860F(a)(4) of the Code and as described in Section 11.01 hereof, or (ii) would not be treated as a "prohibited transaction" within the meaning of Section 860F(a)(2) of the Code that results in the realization of a material amount of gain or loss for federal income tax purposes; (e) The Trustee shall not accept any contribution to any REMIC created hereunder after the Startup Day without an Opinion of Counsel (which shall not be an expense of the Trustee) that such contribution is included within the exceptions provided in Section 860G(d)(2) of the Code and, therefore, will not be subject to the tax imposed by Section 860G(d)(1) of the Code; and (f) Notwithstanding anything to the contrary in this Agreement, the Servicer and the Trustee, at the direction of the Servicer, shall take any other action or refuse to take any action otherwise required (including adjusting the Purchase Price for any Mortgage Loan) where the Servicer deems such action or inaction reasonably necessary to ensure the REMIC status of each REMIC created hereunder under the Code and applicable regulations or to avoid the imposition of any material tax liability on any REMIC created hereunder that will affect amounts distributable to the Certificateholders. (g) In the event that any applicable federal, state or local tax, including interest, penalties or assessments, additional amounts or additions to tax, is imposed on any REMIC created hereunder, such tax shall be treated in the same manner as a Realized Loss and shall be charged against amounts otherwise distributable to the Holders of the Certificates, except as provided in the last sentence of this Section 5.28 (g). The Trustee or, if a Paying Agent has been appointed under Section 4.05, the Paying Agent shall withdraw from the Collection Account sufficient funds to pay or provide for the payment of, and to actually pay, such tax as is estimated to be legally owed by (but such authorization shall not prevent the Trustee or, if a Paying Agent has been appointed under Section 4.05, the Paying Agent from contesting, at 78 the expense of the Trust Fund (other than as a consequence of a breach of its obligations under this Agreement), any such tax in appropriate proceedings, and withholding payment of such tax, if permitted by law, pending the outcome of such proceedings). The Trustee or, if a Paying Agent has been appointed under Section 4.05, the Paying Agent is hereby authorized to and shall segregate, into a separate non-interest bearing account, the net income from any "prohibited transaction" under Code Section 860F(a), the amount of any taxable contribution to any REMIC created hereunder after the Startup Day that is subject to tax under Code Section 860G(d), and 35% of any estimated "net income from foreclosure property" under Section 860G(c) and use such income or amount, to the extent necessary, to pay such tax. To the extent that any such tax is paid to the Internal Revenue Service or applicable state or local tax authorities, the Trustee or a Paying Agent has been appointed under Section 4.05, the Paying Agent shall retain an equal amount from future amounts otherwise distributable to the Holder of the Class A-R Certificate and shall distribute such retained amounts to the Holders of the other Classes of Certificates, to the extent they remain outstanding, until they are fully reimbursed for any amount of such taxes previously charged to the then Holder of the Class A-R Certificate. Neither the Trustee nor the Servicer shall be responsible for any taxes imposed on any REMIC created hereunder except to the extent such taxes arise as a consequence of a breach of their respective obligations under this Agreement. The Trustee shall not be liable hereunder for any taxes imposed on any REMIC hereunder as the result of any direction taken hereunder from the Servicer or any action of the Servicer or Paying Agent hereunder. Section 5.29 Reserve Fund; Yield Maintenance Agreement. (a) On the Closing Date, the Paying Agent shall establish an account (the "Reserve Fund"), which shall be an Eligible Account. The Reserve Fund shall be entitled "Reserve Fund, The Bank of New York Trust Company, N.A., as Trustee for the benefit of the Holders of the Chase Mortage Finance Trust 2007-S4 LIBOR Certificates." On each Distribution Date, the Paying Agent is hereby directed to, and shall therefore, deposit into the Reserve Fund all amounts received under the Yield Maintenance Agreement. For federal and state income tax purposes, the LIBOR Certificateholders will be deemed to be the owners of the related portion of the Reserve Fund and all amounts deposited into the Reserve Fund and shall be taxable on any income earned thereon. The Reserve Fund shall not be an asset of any REMIC. Amounts held in the Reserve Fund shall remain uninvested. The Reserve Fund will be part of the Trust Fund but not part of any REMIC and any payments to the LIBOR Certificates of Basis Risk Shortfall Carryover Amounts with respect to the LIBOR Certificates will not be payments with respect to a "regular interest" in a REMIC within the meaning of Code Section 860G(a)(1). (b) The Depositor hereby directs the Paying Agent, to execute and deliver on behalf of the Trust the Yield Maintenance Agreement and authorizes the Paying Agent to perform its obligations thereunder on behalf of the Trust in accordance with the terms of the Yield Maintenance Agreement. The Yield Maintenance Agreement will provide for the payment of Basis Risk Shortfall Carryover Amounts for one Class of LIBOR Certificates to the extent provided in this Section 5.29(b). On or before the Closing Date, the Paying Agent shall enter into the Yield Maintenance Agreement on behalf of the Trust, with the Counterparty. The Yield Maintenance Agreement shall be part of the Trust Fund but not part of any REMIC. On each Distribution Date, the Paying Agent shall distribute amounts received under the Class A-4 Yield Maintenance Agreement on deposit in the Reserve Fund to the Class A-4 Certificates, up to the Basis Risk Shortfall Carryover Amount for the Class A-4 Certificates. (c) [Reserved.] (d) The Seller, the Depositor and the Certificateholders by acceptance of their Certificates acknowledge and agree that the Paying Agent shall execute, deliver and perform its obligations under the 79 Yield Maintenance Agreement and shall do so solely in its capacity as Paying Agent of the Trust Fund and not in its individual capacity. The Paying Agent is hereby directed to represent and warrant to the Counterparty under the Yield Maintenance Agreement that the beneficial owner for United States federal income tax purposes of payments made under the Yield Maintenance Agreement is a "U.S. person" (as that term is used in section 1.1441-4(a)(3)(ii) of United States Treasury Regulations (the "Regulations")) for United States federal income tax purposes. Every provision of this Agreement relating to the conduct of, affecting the liability of or affording protection to the Paying Agent shall apply to the Paying Agent's execution of the Yield Maintenance Agreement and the performance of its duties and satisfaction of its obligations thereunder. (e) On the 20th calendar day of each month, the Paying Agent shall calculate the Class A-4 Maximum Yield Maintenance Agreement Amount and notify the Counterparty of such amount. On each Distribution Date, the "Class A-4 Maximum Yield Maintenance Agreement Amount" shall be an amount equal to the lesser of: (i) the product of: (A) the excess, if any, of LIBOR (as calculated under the Class A-4 Yield Maintenance Agreement subject to the Rate Cap Ceiling) over the related Cap Strike Rate for that Distribution Date; (B) the related Class A-4 Scheduled Notional Amount for that Distribution Date; and (C) a fraction, the numerator of which is 30 and the denominator of which is 360; and (ii) the related Basis Risk Shortfall Carryover Amount related to the Class A-4 Certificates. (f) If on any Distribution Date the Paying Agent has received any excess amounts from the Yield Maintenance Agreement, such excess amounts shall be returned to the Counterparty via the wiring instructions set forth in the Yield Maintenance Agreement.

All distributions made to Certificateholders shall be based on the Percentage Interest of the Class represented by their respective Certificates, and shall be made either by transfer in immediately available funds to the account of such Holder at a bank or other financial or depository institution having appropriate facilities therefor, if such Holder has so notified the Trustee or, if a Paying Agent has been appointed under Section 4.05, the Paying Agent, in writing at least 10 Business Days prior to the first Distribution Date for which distribution by wire transfer is to be made and such Holder's Certificates of such Class in the aggregate evidence an original denomination of not less than $5,000,000 or such Holder holds a 100% Percentage Interest of such Class or, if not, by check mailed to the address of the Person entitled thereto as it appears on the Certificate Register, except that the final distribution in retirement of the Certificates will be made only upon presentation and surrender of the Certificates at the office specified in the final Distribution Notice. If on any Determination Date, the Servicer determines that there are no Mortgage Loans outstanding and no other funds or assets in the Trust Fund other than the funds in the Certificate Account, the Trustee or if a Paying Agent has been appointed under Section 4.05, the Paying Agent shall promptly send the final distribution notice to each Certificateholder specifying the manner in which the final distribution will be made.

and (xxiv) any material changes in the solicitation, credit-granting, underwriting, origination, acquisition or pool selection criteria or procedures, as applicable, used to originate, acquire or select the new pool assets. The Paying Agent's responsibility for sending the above information to the Certificateholders is limited to the availability, timeliness and accuracy of the information derived from the Servicer which shall be provided as required in this Section 6.02(a). Upon reasonable advance notice in writing if required by federal regulation, the Servicer will provide to each Certificateholder which is a savings and loan association, bank or insurance company certain reports and access during business hours to information and documentation regarding the Mortgage Loans sufficient to permit such Certificateholder to comply with applicable regulations of regulatory authorities with respect to investment in the Certificates; provided, that the Servicer shall be entitled to be reimbursed by each such Certificateholder for the Servicer's actual expenses incurred in providing such reports and access. (b) The Servicer shall cause to be prepared, and the Servicer or the Trustee, as required by applicable law, shall file, any and all tax returns, information statements or other filings required to be delivered to Certificateholders and any governmental taxing authority pursuant to any applicable law with respect to the Trust Fund and the transactions contemplated hereby (the Servicer or the Trustee may, at its option but with the consent of the other, which consent shall not be unreasonably withheld, appoint an organization which regularly engages in the preparation and filing of such documents on a continuous basis for profit and which represents itself to be expert in such matters) and the Servicer shall maintain a record of the information necessary for the application of Section 860E(e) of the Code and shall make such information available as required by Section 860D(a)(6) of the Code; provided, however, that the Servicer shall notify the Trustee of the Trustee's obligation to make any such filings and that any fees of the organization appointed as provided above shall be paid by the Servicer; and provided further that if an organization is employed, as described above, to prepare and file any such filings, neither the Trustee nor the Servicer shall be liable for any errors by such organization. Section 6.03 Advances by the Servicer. If, on any Determination Date, the Servicer determines that any Monthly Payments due on the immediately preceding Due Date have not been received, the Servicer shall, unless it determines in its sole discretion that such amounts will not be recoverable from Late Collections, Liquidation Proceeds or otherwise, make an Advance on or before two Business Days prior to the related Distribution Date in an amount equal to the amount of such delinquent Monthly Payments, after adjustment of any delinquent interest payment for the Servicing Fee. For purposes of this Section 6.03, the delinquent Monthly Payments referred to in the preceding sentence shall be deemed to include an amount equal to the Monthly Payments that would have been due on Mortgage Loans which have been foreclosed or otherwise terminated and in connection with which the Servicer acquired and continues to own the Mortgaged Properties on behalf of the Certificateholders. If the Servicer makes an Advance, it shall on or prior to two Business Days prior to such Distribution Date either (i) deposit in the Collection Account an amount equal to such Advance, (ii) cause to be made an 87 appropriate entry in the records of the Collection Account that funds in such account being held for future distribution or withdrawal have been, as permitted by this Section 6.03, used by the Servicer to make such Advance or (iii) make Advances in the form of any combination of clauses (i) and (ii) aggregating the amount of such Advance. Any funds being held in the Collection Account for future distribution to Certificateholders and so used pursuant to clause (ii) or (iii) above shall be replaced by the Servicer from its own funds by deposit into the Collection Account on or before any subsequent Distribution Date to the extent that funds in the Collection Account on such Distribution Date shall be less than the amount of payments required to be made to Certificateholders on such Distribution Date. Any such Advance shall be included with the distribution to the Certificateholders on the related Distribution Date. If the Servicer determines not to make a Nonrecoverable Advance, it shall on the related Determination Date furnish to the Trustee, any co-trustee, the Paying Agent and each Rating Agency notice of such determination. The Servicer shall be entitled to be reimbursed from the Collection Account for all Advances and Nonrecoverable Advances as provided in Section 5.09. Section 6.04 Allocation of Realized Losses. (a) Prior to each Determination Date, the Servicer shall determine (i) the total amount of Realized Losses, if any, incurred during the related Principal Prepayment Period; (ii) whether and to what extent such Realized Losses constitute Excess Losses; and (iii) the respective portions of such Realized Losses allocable to interest and to principal. (b) The principal portion of any Realized Losses, other than Excess Losses, shall be allocated as follows: first, to the Class B-5 Certificates until the Outstanding Certificate Principal Balance of the Class B-5 Certificates has been reduced to zero; second, to the Class B-4 Certificates until the Outstanding Certificate Principal Balance of the Class B-4 Certificates has been reduced to zero; third, to Class B-3 Certificates until the Outstanding Certificate Principal Balance of the Class B-3 Certificates has been reduced to zero; fourth, to the Class B-2 Certificates until the Outstanding Certificate Principal Balance of the Class B-2 Certificates has been reduced to zero; fifth, to the Class B-1 Certificates until the Outstanding Certificate Principal Balance of the Class B-1 Certificates has been reduced to zero; sixth, to the Class M Certificates until the Outstanding Certificate Principal Balance of the Class M Certificates has been reduced to zero; and seventh, to the Non-PO Class A Certificates on a pro rata basis until the Outstanding Certifciate Principal Balance of the Non-PO Class A Certificates has been reduced to zero; provided, however, that if a Realized Loss occurs with respect to a Discount Mortgage Loan (a) the amount of such Realized Loss equal to the product of (i) the amount of such Realized Loss and (ii) the PO Percentage with respect to such Discount Mortgage Loan will be allocated to Class A-P Certificates and (b) the remainder of such Realized Loss will be allocated as described above; provided further, however, that so long as the Outstanding Certificate Principal Balance of the Class A-3 Certificates is greater than zero, any Realized Losses (other than Excess Losses) that would otherwise be allocated to the Class A-2 Certificates will instead be allocated to the Class A-3 Certificates; provided further, however, that, that so long as the Outstanding Certificate Principal Balance of the Class A-9 Certificates is greater than zero, (A) any Realized Losses (other than Excess Losses) that would otherwise be allocated to the Class A-4 Certificates will instead be allocated to the Class A-9 Certificates, but only in an amount up to the product of (x) the Outstanding Certificate Principal Balance of the Class A-9 Certificates (after reduction of such Outstanding Certificate Principal Balance after giving effect to the pro rata application of Realized Losses directly to the Class A-9 Certificates) and (y) 60.61%, (B) any Realized Losses (other than Excess Losses) that would otherwise be allocated to the Class A-8 Certificates will instead be allocated to the Class A-9 Certificates, but only in an amount up to the product of (x) the Outstanding Certificate Principal Balance of the Class A-9 Certificates (after reduction of such Outstanding Certificate Principal Balance after giving effect to the pro rata application of Realized Losses directly to the Class A-9 Certificates) and (y) 2.36% and (C) any Realized Losses (other than Excess Losses) that would otherwise be allocated to the Class A-12 Certificates will instead be allocated to the Class A-9 88 Certificates, but only in an amount up to the product of (x) the Outstanding Certificate Principal Balance of the Class A-9 Certificates (after reduction of such Outstanding Certificate Principal Balance after giving effect to the pro rata application of Realized Losses directly to the Class A-6 Certificates) and (y) 37.03%. The principal portion of any Excess Losses shall be allocated among all Classes of Certificates on a pro rata basis; provided, however, that the applicable PO Percentage of any Excess Losses on the Discount Mortgage Loans shall be allocated to Class A-P Certificates. (c) As used herein, an allocation of a Realized Loss on a "pro rata basis" among two or more specified Classes of Certificates means an allocation on a pro rata basis, among the various Classes so specified, to each such Class of Certificates on the basis of their Outstanding Certificate Principal Balances (or, in the case of the Class A-6 and Class A-7 Certificates, the lesser of (i) the Original Certificate Principal Balance of such Class of Certificates and (ii) the Outstanding Certificate Principal Balance of such Class of Certificates) prior to giving effect to distributions to be made on such Distribution Date. All Realized Losses and all other losses allocated to a Class of Certificates hereunder will be allocated among the Certificates of such Class in proportion to the Percentage Interests evidenced thereby. (d) In the event that a recovery is made with respect to any Realized Loss, the amount of such recovery shall be treated as a Principal Prepayment and deposited into the Collection Account and distributed on the applicable Distribution Date. Section 6.05 Compensating Interest; Allocation of Certain Interest Shortfalls. (a) Upon a Principal Prepayment of a Mortgage Loan, the Servicer shall deposit into the Collection Account from its own funds, as a reduction of its servicing compensation hereunder, an amount, if any, by which the amount of the interest that would otherwise accrue with respect to such Mortgage Loan from the date of prepayment to the Due Date in the related Due Period at the Net Mortgage Rate exceeds the amount of the interest (adjusted to the Net Mortgage Rate) collected from the Mortgagor with respect to such period (such amount, "Compensating Interest"); provided, however, that with respect to any Distribution Date, the Servicer's obligation to deposit any such amount is limited to an amount equal to the product of (i) one-twelfth of 0.125% and (ii) the aggregate Scheduled Principal Balance of the Mortgage Loans with respect to such Distribution Date. (b) On any Distribution Date, the excess, if any, of (X) Compensating Interest with respect to such Distribution Date over (Y) the amount deposited in the Collection Account pursuant to (a) above for such Distribution Date shall equal the "Compensating Interest Shortfall" with respect to such Distribution Date. On any Distribution Date, the Compensating Interest Shortfall shall be allocated pro rata among the outstanding Classes of Class A, Class M and Class B Certificates based on the amount of interest (disregarding any Basis Risk Shortfall Carryover Amount) to which each such Class would otherwise be paid on such Distribution Date had there been no such Compensating Interest Shortfall. (c) On any Distribution Date, the interest portion of any Realized Losses ("Realized Loss Interest Shortfall") (other than the interest portion of Excess Losses) shall be allocated to the Class of Subordinated Certificates then outstanding having the highest numerical class designation (for this purpose, the Class M Certificates shall be deemed to have a lower numerical class designation than each Class of Class B Certificates) or, if no Class of Subordinated Certificates is then outstanding, to the Class A Certificates (other than the Class A-P Certificates) pro rata among the outstanding Classes of Class A Certificates (other than the Class A-P Certificates) based on the amount of interest (disregarding any Basis Risk Shortfall Carryover Amount) to which each such Class would otherwise be entitled (or in the case of the Class A-6 and Class A-7 Certificates, added to the Outstanding Certificate Principal Balance of such Class, prior to the Class A-6 Accretion Termination Date and Class A-7 Accretion Termination 89 Date, as applicable) on such Distribution Date had there been no such Realized Loss Interest Shortfall. On any Distribution Date, the interest portion of any Excess Losses shall be allocated pro rata among the outstanding Classes of Certificates based upon the amount of interest (disregarding any Basis Risk Shortfall Carryover Amount) to which each such Class would otherwise be entitled (or in the case of the Class A-6 and Class A-7 Certificates, added to the Outstanding Certificate Principal Balance of such Class, prior to the Class A-6 Accretion Termination Date and Class A-7 Accretion Termination Date, as applicable) on such Distribution Date had there been no such Excess Losses allocable to interest; provided, however, that so long as the Outstanding Certificate Principal Balance of the Class A-3 Certificates is greater than zero, the interest portion of any Excess Losses that would otherwise be allocated to the Class A-2 Certificates in accordance with this Section 6.05(c) will instead be allocated to the Class A-3 Certificates; provided further, however, that so long as the Outstanding Certificate Principal Balance of the Class A-9 Certificates is greater than zero, (A) the interest portion of any Excess Losses that would otherwise be allocated to the Class A-4 Certificates in accordance with this Section 6.05(c) will instead be allocated to the Class A-9 Certificates, but only in an amount up to the product of (x) the Outstanding Certificate Principal Balance of the Class A-9 Certificates (after reduction of such Outstanding Certificate Principal Balance after giving effect to the pro rata application of Realized Losses directly to the Class A-9 Certificates) and (y) 60.61%, (B) the interest portion of any Excess Losses that would otherwise be allocated to the Class A-8 Certificates in accordance with this Section 6.05(c) will instead be allocated to the Class A-9 Certificates, but only in an amount up to the product of (x) the Outstanding Certificate Principal Balance of the Class A-9 Certificates (after reduction of such Outstanding Certificate Principal Balance after giving effect to the pro rata application of Realized Losses directly to the Class A-9 Certificates) and (y) 2.36% and (C) the interest portion of any Excess Losses that would otherwise be allocated to the Class A-12 Certificates in accordance with this Section 6.05(c) will instead be allocated to the Class A-9 Certificates, but only in an amount up to the product of (x) the Outstanding Certificate Principal Balance of the Class A-9 Certificates (after reduction of such Outstanding Certificate Principal Balance after giving effect to the pro rata application of Realized Losses directly to the Class A-9 Certificates) and (y) 37.03%. (d) Any interest shortfall resulting from the Relief Act shall be allocated pro rata among the outstanding Classes of Certificates based upon the amount of interest (disregarding any Basis Risk Shortfall Carryover Amount) to which each such Class would otherwise be paid on such Distribution Date. Section 6.06 Subordination. The rights of the Class B Certificateholders to receive distributions in respect of the Class B Certificates on any Distribution Date shall be subordinated to the rights of the Class A and Class M Certificateholders to receive distributions in respect of the Class A and Class M Certificates. The rights of the Class M Certificateholders to receive distributions in respect of the Class M Certificates on any Distribution Date shall be subordinated to the rights of the Class A Certificateholders to receive distributions in respect of the Class A Certificates, respectively. The rights of the Class B-1 Certificateholders to receive distributions in respect of the Class B-1 Certificates on any Distribution Date shall be subordinate to the rights of the Class A and Class M Certificateholders to receive distributions in respect of such Class A and Class M Certificates. Each Class of Class B Certificates (other than the Class B-1 Certificates) is subordinated to the Class A Certificates, the Class M Certificates and each Class of Class B Certificates having a lower numerical class designation than such Class of Class B Certificates. The rights of the Servicer, as servicer, to receive funds from the Collection Account, pursuant to Section 5.09, on account of the Servicing Fee (except as provided in Section 6.05) in respect of each Mortgage Loan, assumption fees, late payment charges and other mortgagor charges, reimbursement of Advances and expenses or otherwise, shall not be subordinated to the rights of the Class A, Class M or Class B Certificateholders. Amounts held by the Servicer or the Paying Agent for future distribution to the Class M or Class B Certificateholders, including, without limitation, in the Collection Account, shall not be distributed in respect of the Class M or Class B Certificates except in 90 accordance with the terms of this Agreement. The Class B Certificateholders are deemed to have granted a security interest in such amounts to the Class A and Class M Certificateholders to secure the rights of the Class A and Class M Certificateholders to receive distributions in priority over the Class B Certificateholders. The Class M Certificateholders are deemed to have granted a security interest in such amounts to the Class A Certificateholders to secure the rights of the Class A Certificateholders to receive distributions in priority over the Class A Certificateholders. Section 6.07 Determination of LIBOR. The meaning of LIBOR applicable to the calculation of the Certificate Rates on the Class A-4 and Class A-5 Certificates for any Interest Accrual Period (other than the initial Interest Accrual Period) will be determined by the Servicer on each Rate Adjustment Date as follows: For any Interest Accrual Period other than the first Interest Accrual Period, "LIBOR" means, with respect to a Yield Maintenance Agreement Remittance Date, the rate determined by the Counterparty to be (i) the per annum rate for deposits in U.S. dollars for a period of one month which appears on the Reuters Page LIBOR01 as of 11:00 a.m., London time, on the day that is two London Business Days prior to the first day of the Interest Accrual Period relating to such Yield Maintenance Agreement Remittance Date (rounded upwards, if necessary, to the nearest 1/100,000 of 1%); (ii) if such rate does not appear on the Reuters Page LIBOR01, LIBOR shall be the arithmetic mean (rounded as aforesaid) of the offered quotations obtained by the Counterparty from the Reference Banks for deposits in U.S. dollars to leading banks in the London interbank market as of approximately 11:00 a.m., London time, on the day that is two London Business Days prior to the first day of the Interest Accrual Period relating to such Yield Maintenance Agreement Remittance Date; or (iii) if fewer than two Reference Banks provide the Counterparty with such quotations, LIBOR shall be the rate per annum which the Counterparty determines to be the arithmetic mean (rounded as aforesaid) of the offered quotations which leading banks in New York City selected by the Counterparty are quoting in the New York interbank market on the first day of the Interest Accrual Period relating to such Yield Maintenance Agreement Remittance Date for deposits in U.S. dollars to the Reference Banks or, if fewer than two such quotations are available, to leading European and Canadian banks. The establishment of LIBOR by the Counterparty on any Rate Adjustment Date and the Servicer's subsequent calculation of the Certificate Rates applicable to the Class A-4 and Class A-5 Certificates for the relevant Interest Accrual Period, in the absence of manifest error, will be final and binding. [END OF ARTICLE VI] ARTICLE VII REPORTS TO BE PREPARED BY THE SERVICER Section 7.01 Servicer Shall Provide Information as Reasonably Required. The Servicer shall furnish to the Trustee or, if a Paying Agent has been appointed pursuant to Section 4.05, the Paying Agent, during the term of this Agreement, such periodic, special, or other reports or information, whether or not provided for herein, as shall be necessary, reasonable, or appropriate in respect to the Trustee or, if a Paying Agent has been appointed pursuant to Section 4.05, the Paying Agent, or otherwise in respect to the purposes of this Agreement, all such reports or information to be as provided by and in accordance with such applicable instructions and directions as the Trustee or, if a Paying Agent has been appointed pursuant to Section 4.05, the Paying Agent may reasonably require. 91 Section 7.02 Federal Information Returns and Reports to Certificateholders. (a) For federal income tax purposes, the taxable year of each REMIC Pool shall be a calendar year and the Servicer shall maintain or cause the maintenance of the books of each REMIC Pool on the accrual method of accounting. (b) The Servicer or anyone acting on its behalf pursuant to Section 2.04(g) shall prepare and file or cause to be filed with the Internal Revenue Service federal tax or information returns with respect to the Trust Fund, each REMIC Pool and the Certificates containing such information and at the times and in the manner as may be required by the Code or applicable Treasury regulations, and shall furnish to each Certificateholder at any time during the calendar year for which such returns or reports are made such statements or information at the times and in the manner as may be required thereby. Without limitation on any other requirement of this Section 7.02, the Servicer shall make available the information necessary for the application of Section 860E(e) of the Code within 60 days of such request. With respect to the Class A-R Certificate, the Servicer shall provide such information or cause such information to be provided to (i) the Internal Revenue Service, (ii) the transferor of a Class A-R Certificate to a Disqualified Organization and (iii) a Pass-Thru Entity that holds a Class A-R Certificate with one or more record holders that are Disqualified Organizations. The Servicer also shall provide or cause to be provided promptly the above described computation and information relating to the tax on transfers to Disqualified Organizations or holdings by Pass-Thru Entities within sixty (60) days after becoming aware of the transfer to a Disqualified Organization or Pass-Thru Entity with one or more Disqualified Organization owners, as the case may be. In addition, except as may be provided in Treasury Regulations, any Person holding an interest in a Pass-Thru Entity as a nominee for another will, with respect to such interest, be treated as a Pass-Thru Entity. In connection with the foregoing, the Servicer shall provide the name, address and telephone number of the person who can be contacted to obtain information required to be reported to the holders of regular interests in any REMIC created hereunder (the "REMIC Reporting Agent") as required by IRS Form 8811. The Trustee hereby designates the Servicer to serve as the REMIC Reporting Agent. The Servicer shall indicate the elections to treat each of the REMIC Pools as a REMIC (which elections shall apply to the taxable period ending December 31, 2007 and each calendar year thereafter) in such manner as the Code or applicable Treasury regulations may prescribe. The Trustee shall sign all tax and information returns filed pursuant to this Section 7.02 and any other returns as may be required by the Code, and in doing so shall rely entirely upon, and shall have no liability for information provided by, or calculations provided by, the Servicer. The Servicer is hereby designated as the agent of the Holder of the Class A-R Certificate who shall be the "tax matters person" (within the meaning of Treas. Reg. Section 1.860F-4(d)) for each REMIC Pool. Any Holder of a Class A-R Certificate will by acceptance thereof so appoint the Servicer as agent and attorney-in-fact for the purpose of acting as tax matters person. In the event that the Code or applicable Treasury regulations prohibit the Trustee from signing tax or information returns or other statements, or the Servicer from acting as tax matters person (as an agent or otherwise), the Trustee or the Servicer, as the case may be, shall take whatever action that in its sole good faith judgment is necessary for the proper filing of such information returns or for the provision of a tax matters person, including designation of the Holder of a Class A-R Certificate to sign such returns or act as tax matters person. Each Holder of a Class A-R Certificate shall be bound by this Section 7.02 by virtue of its acceptance of a Class A-R Certificate. [END OF ARTICLE VII] ARTICLE VIII THE DEPOSITOR AND THE SERVICER 92 Section 8.01 Indemnification; Third Party Claims. The Servicer agrees to indemnify the Depositor and the Trustee and hold the Depositor and the Trustee, their officers, directors, employees and agents harmless against any and all claims, losses, penalties, fines, forfeitures, legal fees and related costs, judgments, and any other costs, fees and expenses that the Depositor or the Trustee, or their officers, directors, employees or agents may sustain in any way related to failure of the Servicer to perform its duties and service the Mortgage Loans in compliance with the terms of this Agreement; provided that no such indemnification shall be required with respect to acts of a prior Servicer. The Servicer shall immediately notify the Depositor and the Trustee if a claim is made by a third party with respect to this Agreement or the Mortgage Loans, assume (with the consent of the Depositor and the Trustee) the defense of any such claim and pay all expenses in connection therewith, including counsel fees, and promptly pay, discharge and satisfy any judgment or decree which may be entered against it, the Depositor or the Trustee, their officers, directors, employees or agents in respect of such claim. This right to indemnification shall survive the termination of this Agreement. Section 8.02 Merger or Consolidation of the Depositor or the Servicer. The Depositor and the Servicer will each keep in full effect its existence, rights and franchises as a corporation, and will obtain and preserve its qualification to do business as a foreign corporation in each jurisdiction in which such qualification is or shall be necessary to protect the validity and enforceability of this Agreement, the Certificates or any of the Mortgage Loans and to perform its duties under this Agreement. The Servicer will not sell all or substantially all of its assets without the prior written consent of the Depositor and the Trustee which shall not be unreasonably withheld or delayed. Any Person into which the Depositor or the Servicer may be merged or consolidated, or to whom the Depositor or the Servicer has sold substantially all of its assets, or any corporation resulting from any merger, conversion or consolidation to which the Depositor or the Servicer shall be a party, or any Person succeeding to the business of the Depositor or the Servicer, shall be the successor of the Depositor or the Servicer hereunder, without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding; provided, however, that the successor or surviving Person to the Servicer shall satisfy the requirements of Section 8.05 with respect to the qualifications of a successor to the Servicer. Notwithstanding anything else in this Section 8.02 and Section 8.04 to the contrary, the Servicer may assign its rights and delegate its duties and obligations under this Agreement; provided that the Person accepting such assignment or delegation shall be a Person which is qualified to service mortgage loans on behalf of FNMA or FHLMC, is approved in advance in writing by the Trustee and the Depositor, is willing to service the Mortgage Loans and executes and delivers to the Depositor and the Trustee an agreement, in form and substance reasonably satisfactory to the Depositor and the Trustee, which contains an assumption by such Person of the due and punctual performance and observance of each covenant and condition to be performed or observed by the Servicer under this Agreement; provided further that each Rating Agency's rating of any of the Classes of Certificates that have been rated in effect immediately prior to such assignment and delegation will not be qualified or reduced or withdrawn as a result of such assignment and delegation. In the case of any such assignment and delegation, the Servicer shall be released from its obligations as Servicer under this Agreement, except that the Servicer shall remain liable for all liabilities and obligations incurred by it as Servicer hereunder prior to the satisfaction of the conditions to such assignment and delegation set forth in the next preceding sentence. Section 8.03 Limitation on Liability of the Depositor, the Servicer, the Trustee and Others. Neither the Depositor, the Servicer nor any of the directors, officers, employees or agents of the Depositor or the Servicer shall be under any liability to the Trustee or the Certificateholders for any action taken, or for refraining from the taking of any action, in good faith pursuant to this Agreement, or for errors in judgment; provided, however, that this provision shall not protect the Depositor or the Servicer against 93 any breach of warranties or representations made herein, or failure to perform its obligations in strict compliance with this Agreement, or any liability which would otherwise be imposed by reason of any breach of the terms and conditions of this Agreement. The Depositor, the Servicer, the Trustee, and any director, officer, employee or agent of the Depositor, the Servicer or the Trustee may rely in good faith on any document of any kind prima facie properly executed and submitted by any Person respecting any matters arising hereunder. Neither the Depositor, the Servicer nor the Trustee shall be under any obligation to appear in, prosecute or defend any legal action which is not incidental to its respective duties to service the Mortgage Loans in accordance with this Agreement and which in its opinion may cause it to incur any expenses or liability; provided, however, that the Depositor, the Servicer or the Trustee may in its discretion (and, in the case of the Depositor or the Servicer, with the consent of the Trustee, which consent shall not be unreasonably withheld) undertake any such action which it may deem necessary or desirable with respect to this Agreement and the rights and duties of the parties hereto. In such event, the legal expenses and costs of such action and any liability resulting therefrom shall be expenses, costs and liabilities payable from the Collection Account and the Depositor, the Servicer or the Trustee shall be entitled to be reimbursed therefor out of the Collection Account as provided by Section 5.09; provided that no such right of reimbursement shall exist with respect to the Servicer when such claim relates to the failure of the Servicer to service the Mortgage Loans in strict compliance with the terms of this Agreement or to a breach of a representation or warranty made by the Servicer hereunder. Section 8.04 Depositor and Servicer Not to Resign. Except as described in Section 8.02, neither the Depositor nor the Servicer shall assign this Agreement or resign from the obligations and duties hereby imposed on it except by mutual consent of the Depositor, the Servicer and all of the Certificateholders unless the determination is made that its duties hereunder are no longer permissible under applicable law and such incapacity cannot be cured by the Depositor or the Servicer. Any such determination permitting the resignation of the Depositor or the Servicer shall be evidenced by an opinion of independent counsel to such effect delivered to the Trustee which opinion of counsel shall be in form and substance acceptable to the Trustee. Upon any such assignment or resignation, the Depositor or the Servicer, as appropriate, shall send notice to all Certificateholders of the effect of such assignment or resignation upon the then current rating of the Class of Certificates by each Rating Agency whose rating on such Class is then in effect. No such resignation shall become effective until a successor shall have assumed the Depositor's or the Servicer's responsibilities and obligations hereunder in the manner provided in Section 8.05. Any purported assignment or resignation which does not comply with the requirements of this Section shall be of no effect. Section 8.05 Successor to the Servicer. In connection with the termination of the Servicer's responsibilities and duties under this Agreement pursuant to Section 8.04 or 9.01, the Trustee shall succeed to and assume all of the Servicer's responsibilities, rights, duties and obligations as Servicer (but not in any other capacity) under this Agreement (except that the Trustee shall not be obligated to make Advances if prohibited by applicable law nor to effectuate repurchases or substitutions of Mortgage Loans pursuant to Section 2.02 and except that the Trustee makes no representations and warranties pursuant to Sections 3.01 and 3.02). Prior to the termination of the Servicer's responsibilities, duties and liabilities under this Agreement, the Trustee may appoint a successor having a net worth of not less than $15,000,000 and which is a FNMA or FHLMC approved seller/servicer in good standing and which shall succeed to all rights and assume all of the responsibilities, duties and liabilities of the Servicer under this Agreement, except as aforesaid, if the Trustee receives a letter from each Rating Agency that such appointment would not result in a reduction or withdrawal of the current rating of any Class of Certificates that is rated by a Rating Agency. Any co-trustee appointed pursuant to Section 10.10 for purposes of this Section 8.05 shall have an obligation to make Advances pursuant to Section 6.03 during such time as the Trustee is the Servicer, which obligation shall be joint and several with that of the Trustee as Servicer. If the Trustee has become the successor to the Servicer in accordance with this Section or Section 9.03, then notwithstanding the above, the Trustee may, if it shall be unwilling to so act, 94 or shall, if it is unable to so act, appoint, or petition a court of competent jurisdiction to appoint, any established housing and home finance institution having a net worth of not less than $15,000,000 and which is a FNMA or FHLMC approved seller/servicer in good standing as the successor to the Servicer hereunder in the assumption of all of the responsibilities, duties or liabilities of the Servicer hereunder. In connection with any such appointment and assumption, the Trustee may make such arrangements for the compensation of such successor out of payments on Mortgage Loans as it and such successor shall agree or such court shall determine; provided, however, that no such compensation shall be in excess of that permitted under this Agreement without the consent of all of the Certificateholders. If the Trustee is acting as Servicer, the Trustee shall be entitled to all compensation of the Servicer hereunder, and all such compensation due to the Trustee as Servicer shall be in addition to all compensation it is entitled to as Trustee under this Agreement. If the Servicer's duties, responsibilities and liabilities under this Agreement should be terminated pursuant to Section 8.02, 8.04 or 9.01, the Servicer shall discharge such duties and responsibilities during the period from the date it acquires knowledge of such termination until the effective date thereof with the same degree of diligence and prudence which it is obligated to exercise under this Agreement, and shall take no action whatsoever that might impair or prejudice the rights or financial condition of its successor or the Trust Fund. The resignation or removal of the Servicer pursuant to Section 8.02, 8.04 or 9.01 shall not become effective until a successor shall be appointed pursuant to this Section and shall in no event relieve the Servicer of liability for breach of the representations and warranties made pursuant to Section 3.02. Any successor appointed as provided herein shall execute, acknowledge and deliver to the Servicer and to the Trustee an instrument accepting such appointment, whereupon such successor shall become fully vested with all the rights, powers, duties, responsibilities, obligations and liabilities of the Servicer, with like effect as if originally named as a party to this Agreement and the Certificates. Any termination or resignation of the Servicer or this Agreement pursuant to Section 8.02, 8.04, 9.01 or 11.01 shall not affect any claims that the Trustee may have against the Servicer for events or actions taken or not taken by the Servicer arising prior to any such termination or resignation. The Servicer shall timely deliver to the successor the funds that were, or were required to be, in the Collection Account and the Escrow Account, if any, and all Mortgage Files and related documents, statements and recordkeeping held by it hereunder and the Servicer shall account for all funds and shall execute and deliver such instruments and do such other things as may reasonably be required to more fully and definitely vest and confirm in the successor all such rights, powers, duties, responsibilities, obligations and liabilities of the Servicer. Upon a successor's acceptance of appointment as such, the Servicer shall notify, in writing, the Trustee, the Certificateholders and each Rating Agency of such appointment. Section 8.06 Maintenance of Ratings. The Servicer shall cooperate with the Depositor and take any action that may be reasonably necessary to maintain the current rating or ratings on the Certificates. [END OF ARTICLE VIII] ARTICLE IX DEFAULT Section 9.01 Events of Default. If one or more of the following Events of Default shall occur and be continuing, that is to say: 95 (a) any failure by the Servicer to remit any payment required to be made or distributed under the terms of this Agreement which continues unremedied for a period of three (3) Business Days after the date upon which written notice of such failure, requiring the same to be remedied, shall have been given to the Servicer by the Trustee, the Paying Agent or the Depositor or to the Servicer, the Trustee, the Paying Agent and the Depositor by the Holders of Certificates of any Class evidencing, as to such Class, Percentage Interests aggregating not less than 25%; or (b) a breach by the Servicer in a material respect of any representation or warranty set forth in Section 3.02, or failure on the part of the Servicer duly to observe or perform in any material respect any other of the covenants or agreements on the part of the Servicer set forth in this Agreement, which continues unremedied for a period of 60 days after the date on which written notice of such breach or failure, requiring the same to be remedied, shall have been given to the Servicer by the Trustee or the Depositor or to the Servicer, the Trustee and the Depositor by the Holders of Certificates of any Class evidencing, as to such Class, Percentage Interests aggregating not less than 25%; or (c) the Servicer shall notify the Trustee and any Paying Agent appointed pursuant to Section 4.05 in writing that it is unable to make an Advance required to be made in accordance with Section 6.03; or; (d) a decree or order of a court or agency or supervisory authority having jurisdiction for the appointment of a conservator or receiver or liquidator in any insolvency, readjustment of debt, marshalling of assets and liabilities or similar proceedings, or for the winding-up or liquidation of its affairs, shall have been entered against the Servicer and such decree or order shall have remained in force undischarged or unstayed for a period of 60 days; or (e) the Servicer shall consent to the appointment of a conservator or receiver or liquidator in any insolvency, readjustment of debt, marshalling of assets and liabilities or similar proceedings of or relating to the Servicer or of or relating to all or substantially all of the Servicer's property; or (f) the Servicer shall admit in writing its inability to pay its debts generally as they become due, file a petition to take advantage of any applicable insolvency or reorganization statute, make an assignment for the benefit of its creditors, or voluntarily suspend payment of its obligations; then, and in each and every such case, so long as an Event of Default shall not have been remedied, upon receiving notice or knowledge of such event, the Trustee shall notify the Certificateholders and each Rating Agency of such Event of Default. The Trustee may, upon receipt of such notice or knowledge, and at the written direction of the Holders of Certificates evidencing Percentage Interests aggregating more than 50%, shall, by notice in writing to the Servicer, terminate all the rights and obligations of the Servicer under this Agreement and in and to the Mortgage Loans and the proceeds thereof. On or after the receipt by the Servicer of such written notice, all authority and power of the Servicer under this Agreement, whether with respect to the Mortgage Loans or otherwise, shall pass to and be vested in the successor appointed pursuant to Section 8.05. Upon written request from the Trustee, the Servicer shall prepare, execute and deliver, any and all documents and other instruments, place in such successor's possession all Mortgage Files, and do or accomplish all other acts or things necessary or appropriate to effect the purposes of such notice of termination, whether to complete the transfer and endorsement or assignment of the Mortgage Loans and related documents, or otherwise, at the Servicer's sole expense. The Servicer agrees to cooperate with the Trustee and any co-trustee in effecting the termination of the Servicer's responsibilities and rights hereunder, including, without limitation, the transfer to such successor for administration by it of all cash amounts which shall at the time be credited or should have been credited by the Servicer to the Collection Account or Escrow Account or thereafter received with respect to the Mortgage Loans. The Trustee will have no obligation to take any action or institute, 96 conduct or defend any litigation under this Agreement at the request, order or direction of any of the Holders of Certificates unless such Certificateholders have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities which the Trustee may incur. The Paying Agent shall provide information regarding the Certificateholders available to the Paying Agent in order to allow the Trustee to comply with the provisions above. Section 9.02 Waiver of Defaults. The Trustee may waive any default by the Servicer in the performance of its obligations hereunder and its consequences, except that a default in the making of any required distribution on any of the Certificates may only be waived by the Holders of a majority of the Percentage Interests of the affected Certificateholders. Upon any such waiver of a past default, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been remedied for every purpose of this Agreement. No such waiver shall extend to any subsequent or other default or impair any right consequent thereon except to the extent expressly so waived. Section 9.03 Trustee to Act; Appointment of Successor. On and after the time the Servicer receives a notice of termination pursuant to Section 9.01, the Trustee or a successor servicer appointed by it shall be the successor in all respects to the Servicer to the extent provided in Section 8.05. Section 9.04 Notification to Certificateholders and the Rating Agencies. (a) Upon any such termination pursuant to Section 9.01, the Trustee shall give prompt written notice thereof to Certificateholders at their respective addresses appearing in the Certificate Register and to each Rating Agency. (b) Within sixty (60) days of a Responsible Officer of the Trustee having received written notice of the occurrence of any Event of Default, the Trustee shall transmit by mail to all Holders of Certificates notice of each such Event of Default hereunder known to the Trustee, unless such Event of Default shall have been cured or waived. (c) The Paying Agent shall provide information regarding the Certificateholders available to the Paying Agent in order to allow the Trustee to comply with the provisions above. [END OF ARTICLE IX] ARTICLE X CONCERNING THE TRUSTEE Section 10.01 Duties of Trustee. The Trustee, prior to the occurrence of an Event of Default and after the curing of all Events of Default which may have occurred, undertakes to, and is empowered to, perform such duties and only such duties as are specifically set forth in this Agreement. Any permissive right of the Trustee as enumerated in this Agreement shall not be construed as a duty; provided that in case an Event of Default has occurred (which has not been cured), the Trustee shall exercise such of the rights and powers vested in it by this Agreement, and use the same degree of care and skill in their exercise as a prudent man would exercise or use under the circumstances in the conduct of such man's own affairs. No provision of this Agreement shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act or its own willful misconduct; provided, however, that: 97 (i) Prior to the occurrence of an Event of Default, and after the curing of all such Events of Default which may have occurred, the duties and obligations of the Trustee shall be determined solely by the express provisions of this Agreement, the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Agreement, no implied covenants or obligations shall be read into this Agreement against the Trustee and, in the absence of bad faith on the part of the Trustee, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of this Agreement; (ii) The Trustee shall not be liable for an error of judgment made in good faith by a Responsible Officer or Responsible Officers of the Trustee, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts; and (iii) The Trustee shall not be liable with respect to any action taken, suffered or omitted to be taken by it in good faith in accordance with the direction of Certificateholders of any Class holding Certificates which evidence, as to such Class, Percentage Interests aggregating not less than 25% as to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Agreement. (iv) The Trustee shall execute the Letter of Representations, a form of which is attached hereto as Exhibit P, on behalf of the Depositor. Section 10.02 Certain Matters Affecting the Trustee. Except as otherwise provided in Section 10.01: (a) The Trustee may rely upon and shall be protected in acting or refraining from acting upon any resolution, Officers' Certificate, certificate 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; (b) The Trustee may consult with counsel, and any advice or Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken or suffered or omitted by it hereunder in good faith and in accordance with such advice or Opinion of Counsel; (c) The Trustee shall be under no obligation to exercise any of the trusts or powers vested in it by 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 reasonable security or indemnity against the costs, expenses and liabilities which may be incurred therein or thereby; (d) Neither the Trustee nor any of its directors, officers, employees or agents shall be personally liable for any action taken, suffered or omitted by it in good faith and believed by it or any of them to be authorized or within the discretion or rights or powers conferred upon the Trustee by this Agreement; (e) Prior to the occurrence of an Event of Default hereunder and after the curing of all Events of Default which may have occurred, the Trustee shall not 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 98 Holders of Certificates of any Class evidencing, as to such Class, Percentage Interests aggregating not less than 25% (in the case of conflicting requests by two or more 25% or greater Percentage Interests, the Trustee shall act in accordance with the first such request); provided, however, that if the payment within a reasonable time to the Trustee 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, not reasonably assured to the Trustee by the security afforded to it by the terms of this Agreement, the Trustee may require reasonable indemnity against such expense or liability as a condition to such proceeding. The reasonable expense of every such examination shall be paid by the Servicer, if an Event of Default shall have occurred and is continuing, and otherwise by the Certificateholder requesting the investigation; (f) The Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents, subcontractors or attorneys; and (g) Nothing in this Agreement shall be construed to require the Trustee (except as might otherwise be required in its capacity as successor Servicer) to expend its own funds. Section 10.03 Trustee Not Liable for Certificates or Mortgage Loans. The recitals contained herein shall be taken as the statements of the Depositor or the Servicer, as the case may be, and the Trustee assumes no responsibility for their correctness. The Trustee makes no representations or warranties as to the validity or sufficiency of this Agreement or of the Certificates, of any Mortgage Loan or related document or the Trust Estate. The Trustee shall not be accountable for the use or application by the Depositor or the Servicer 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 or the Servicer in respect of the Mortgage Loans or deposited in or withdrawn from the Collection Account by the Depositor or the Servicer or the Certificate Account by the Paying Agent. The Trustee shall have no responsibility for the timeliness or the amount of payments made by the Paying Agent to the Certificateholders. Section 10.04 Trustee May Own Certificates. The Trustee in its individual or any other capacity may become the owner or pledgee of Certificates with the same rights it would have if it were not Trustee. Section 10.05 Fees and Expenses. The Paying Agent, from moneys received from the Servicer, covenants and agrees to pay to the Trustee and its agents a monthly fee (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust) equal to the product of (a) the aggregate Principal Balance of the Mortgage Loans as of the Determination Date in the preceding month and (b) one-twelfth of 0.000010, and the Servicer will pay or reimburse the Trustee, or its agents upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee or its agents in accordance with any of the provisions of this Agreement (including the reasonable compensation and the expenses and disbursements of its counsel and of all persons not regularly in its employ, and the expenses incurred by the Trustee in connection with the appointment of an office or agency pursuant to Section 10.11) and the Servicer shall indemnify and hold harmless the Trustee its officers, directors, employees and agents from and against any and all claims, liabilities, losses or expenses (including but not limited to reasonable attorneys fees) incurred in connection with the administration of this Trust and the performance of its duties hereunder provided that the Servicer shall not be required to reimburse any such expense or indemnify against any such loss or liability incurred by the Trustee through the Trustee's own negligence or bad faith. Notwithstanding anything to the contrary in this Agreement, this Section shall survive the termination of this Agreement. Section 10.06 Eligibility Requirements for Trustee. The Trustee hereunder shall at all times be an entity having its principal office in a state and city acceptable to the Depositor and organized and doing business under the laws of such state or the United States of America, authorized under such laws to 99 exercise corporate trust powers, having a combined capital and surplus of at least $50,000,000 and subject to supervision or examination by federal or state authority. The Trustee shall not be an Affiliate of either Seller or the Depositor. If such entity publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. In case at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, the Trustee shall resign immediately in the manner and with the effect specified in Section 10.07. Section 10.07 Resignation and Removal of the Trustee. The Trustee, and any co-trustee may at any time resign and be discharged from the trusts hereby created by giving written notice thereof to the Depositor, the Servicer and each Rating Agency. Upon receiving such notice of resignation, the Depositor shall promptly appoint a successor trustee or co-trustee by written instrument, in duplicate, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor trustee; provided that such appointment does not result in a reduction or withdrawal of the rating of any of the Classes of Certificates that have been rated. If no successor trustee shall have been so appointed and have accepted appointment within thirty (30) days after the giving of such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor trustee. If at any time, the Trustee shall cease to be eligible in accordance with the provisions of Section 10.06 and shall fail to resign after written request therefor by the Depositor, or if at any time the Trustee shall become incapable of acting, or shall be adjudged bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, then the Depositor may remove the Trustee and appoint a successor trustee by written instrument, in duplicate, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee. The Holders of Certificates evidencing in the aggregate more than 50% of Percentage Interest may at any time remove the Trustee and appoint a successor trustee by written instrument or instruments, in triplicate, signed by such Holders or their attorneys-in-fact duly authorized, one complete set of which instruments shall be delivered to the Depositor, one complete set to the Trustee so removed and one complete set to the successor so appointed. Any resignation or removal of the Trustee or any resignation of any co-trustee and appointment of a successor trustee or co-trustee pursuant to any of the provisions of this Section shall become effective upon acceptance of appointment by the successor trustee as provided in Section 10.08, or upon acceptance of appointment by a co-trustee, as applicable, unless with respect to a co-trustee, the Trustee receives written notice from each Rating Agency that the failure to appoint a successor co-trustee would not result in a withdrawal or reduction of the rating of any of the Classes of Certificates that have been rated, in which case the resignation of any co-trustee shall be effective upon receipt of such written notice. Any co-trustee may not be removed unless the Depositor and the Trustee each receive written notice from each Rating Agency that such removal would not result in a withdrawal or reduction of the rating of any of the Classes of Certificates that have been rated, in which case the removal of any co-trustee shall be effective upon receipt of such written notice. Section 10.08 Successor Trustee. Any successor trustee appointed as provided in Section 10.07 shall execute, acknowledge and deliver to the Depositor and to its predecessor trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor trustee shall become effective, and such successor trustee shall become effective and such successor 100 trustee, without any further act, deed or conveyance, shall become fully vested with all the rights, powers, duties and obligations of its predecessor hereunder, with the like effect as if originally named as trustee herein. The predecessor trustee shall deliver to the successor trustee all Mortgage Files and related documents and statements held by it hereunder, and the Depositor, the Servicer and the predecessor trustee shall execute and deliver such instruments and do such other things as may reasonably be required for more fully and certainly vesting and confirming in the successor trustee all such rights, powers, duties and obligations. No successor trustee shall accept appointment as provided in this Section unless at the time of such acceptance such successor trustee shall be eligible under the provisions of Section 10.06. Prior to the appointment of any successor trustee becoming effective, the Depositor shall have received from each Rating Agency written confirmation that such appointment would not result in a reduction of the rating of the Class A or Class M Certificates. Upon acceptance of appointment by a successor trustee as provided in this Section, the Servicer shall mail notice of the succession of such trustee hereunder to all Holders of Certificates at their addresses as shown in the Certificate Register, to the Servicer, any Sub-Servicer and to each Rating Agency. If the Depositor fails to mail such notice within ten (10) days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be mailed at the expense of the Depositor. Section 10.09 Merger or Consolidation of Trustee. Any entity into which the Trustee may be merged or converted or with which it may be consolidated or any entity resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any entity succeeding to the business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be eligible under the provisions of Section 10.06, without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding. Section 10.10 Appointment of Co-Trustee or Separate Trustee. 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 the same may at the time be located, the Depositor and the Trustee acting jointly shall have the power and shall execute and deliver all instruments to appoint one or more Persons approved by the Trustee to act as co-trustee or co-trustees, jointly with the Trustee, of any part of the Trust Fund, and to vest in such Person or Persons, in such capacity, such title to the Trust Fund, or any part thereof, and, subject to the other provisions of this Section 10.10, such powers, duties, obligations, rights and trusts as the Depositor and the Trustee may consider necessary or desirable. If the Depositor shall not have joined in such appointment within fifteen (15) days after the receipt by it of a request so to do, or in case an Event of Default shall have occurred and be continuing, the Trustee alone shall have the power to make such appointment. No co-trustee or separate trustee hereunder shall be required to meet the terms of eligibility as a successor trustee under Section 10.06, hereunder, and no notice to Holders of Certificates of the appointment of co-trustee(s) or separate trustee(s) shall be required under Section 10.08 hereof. In the case of any appointment of a co-trustee or separate trustee pursuant to this Section 10.10, all rights, powers, duties and obligations conferred or imposed upon the Trustee shall be conferred or imposed upon and exercised or performed by the Trustee and such separate trustee or co-trustee jointly and severally, 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 successor to the 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 by such separate trustee or co-trustee at the direction of the Trustee. 101 Every instrument appointing any separate trustee or co-trustee shall refer to this Agreement and the conditions of this Article X. Each separate trustee and co-trustee, upon its acceptance of the trusts conferred, shall be vested with the estates or property specified in its instrument of appointment, either jointly with the Trustee or separately, as may be provided therein, subject to all the provisions of this Agreement, specifically including every provision of this Agreement relating to the conduct of, affecting the liability of, or affording protection to, the Trustee. Every such instrument shall be filed with the Trustee. 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. Section 10.11 Appointment of Office or Agency. The Trustee may appoint an office or agency in The City of New York where Certificates may be surrendered for registration of transfer or exchange.

[END OF ARTICLE X] 102 ARTICLE XI TERMINATION Section 11.01 Termination. The respective obligations and responsibilities of the Depositor, the Servicer (except the duty to pay the Trustee's fees and expenses and indemnification hereunder) and the Trustee shall terminate upon (i) the later of the final payment or other liquidation (or any Advance with respect thereto) of the last Mortgage Loan or the disposition of all property acquired upon foreclosure or deed in lieu of foreclosure of any Mortgage Loan and the remittance of all funds due hereunder; or (ii) at the option of the Servicer, on any Distribution Date which occurs in the month next following a Due Date on which the aggregate unpaid Principal Balance of all Outstanding Mortgage Loans is less than 10% of the aggregate unpaid Principal Balance of the Mortgage Loans on the Cut-off Date, so long as the Servicer deposits or causes to be deposited in the Collection Account during the Principal Prepayment Period related to such Distribution Date (and provides notice to the Trustee with a copy to the Paying Agent appointed pursuant to Section 4.05 of its intention to so deposit on or before 20th day of such Principal Prepayment Period) an amount equal to the Purchase Price for each Outstanding Mortgage Loan, less any unreimbursed Advances made with respect to any Mortgage Loan (which amount shall offset completely any unreimbursed Advances for which the Servicer is otherwise entitled to reimbursement), and, with respect to all property acquired in respect of any Mortgage Loan remaining in the Trust Fund, an amount equal to the fair market value of such property, as determined by an appraisal to be conducted by an appraiser selected by the Trustee, less unreimbursed Advances made with respect to any Mortgage Loan with respect to which property has been acquired; provided, however, that in no event shall the trust created hereby continue beyond 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. Notwithstanding the foregoing, a termination may be effected by the making of such optional repurchases only if the termination of the Trust Fund satisfies the requirement for a "qualified liquidation" of the Trust Fund within the meaning of Section 860F(a)(4) of the Code and the purchases of the Outstanding Mortgage Loans pursuant to this Section 11.01 will not constitute "prohibited transactions" within the meaning of Section 860F(a)(2) of the Code. Notice of any termination, specifying the Distribution Date upon which all Certificateholders may surrender their Certificates to the Trustee or, if a Paying Agent has been appointed pursuant to Section 4.05, the Paying Agent for payment and cancellation, shall be given promptly by the Trustee or, if a Paying Agent has been appointed under Section 4.05, the Paying Agent, (upon direction by the Depositor ten (10) days prior to the date such notice is to be mailed) by signed letter to Certificateholders and each Rating Agency mailed no later than the 25th day of the month preceding the month of such final distribution specifying (i) the Distribution Date upon which final payment on the Certificates will be made upon presentation and surrender of Certificates at the office or agency of the Trustee or, if a Paying Agent has been appointed under Section 4.05, the Paying Agent, therein designated and (ii) that the Record Date otherwise applicable to such Distribution Date is not applicable, payments being made only upon presentation and surrender of the Certificates at the office or agency of the Trustee or, if a Paying Agent has been appointed under Section 4.05, the Paying Agent, therein specified. The Servicer shall indicate the date of adoption of the plan of qualified liquidation in a statement attached to the final federal income tax return of each REMIC Pool. After giving such notice, the Trustee or if a Paying Agent has been appointed under Section 4.05, the Paying Agent shall not register the transfer or exchange of any Certificates. If such notice is given in connection with the Servicer's election to purchase the Outstanding Mortgage Loans, the Servicer shall deposit in the Collection Account after adoption of the plan during the applicable Principal Prepayment Period an amount equal to the purchase price as determined as provided in clause (ii) of the preceding paragraph and on the Distribution Date on which such termination is to occur, Certificateholders will be entitled to the amount of such purchase price but not amounts in excess thereof, all as provided herein. Upon presentation and surrender of the Certificates, the Trustee, or if a 103 Paying Agent has been appointed under Section 4.05, the Paying Agent shall notify the Servicer and the Servicer shall cause to be distributed to Certificateholders an amount equal to (a) the amount otherwise distributable on such Distribution Date, if not in connection with a purchase; or (b) if the Servicer elected to so purchase, the purchase price determined as provided in clause (ii) of the preceding paragraph. Following such final deposit the Trustee shall promptly release to the Servicer the Mortgage Files for the remaining Mortgage Loans, and the Trustee shall execute all assignments, endorsements and other instruments necessary to effectuate such transfer and shall have no further responsibility with regard to said Mortgage Files. If all of the Certificateholders shall not surrender their Certificates for cancellation within three (3) months after the time specified in the above-mentioned written notice, at the close of the 90 day period beginning after the written notice is given, each remaining Certificateholder will be credited with an amount that would have been otherwise distributed to such Certificateholder, and the Trustee or, if a Paying Agent has been appointed under Section 4.05, the Paying Agent, 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 three (3) months after the second notice all the Certificates shall not have been surrendered for cancellation, the Trustee or, if a Paying Agent has been appointed under Section 4.05, the Paying Agent, shall appoint an agent to take appropriate and reasonable 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 which remain in the Trust Fund hereunder. [END OF ARTICLE XI] ARTICLE XII MISCELLANEOUS PROVISIONS Section 12.01 Severability of Provisions. If any one or more of the covenants, agreements, provisions or terms of this Agreement shall be for any reason whatsoever held invalid, then such covenants, agreements, provisions or terms shall be deemed severable from the remaining covenants, agreements, provisions or terms of this Agreement and shall in no way affect the validity or enforceability of the other provisions of this Agreement. Section 12.02 Limitation on Rights of Certificateholders. The death or incapacity of any Certificateholder shall not operate to terminate this Agreement or the Trust Fund, nor entitle such Certificateholder's legal representatives or heirs to claim an accounting or to take any action or proceeding in any court for a partition or winding-up of the Trust Fund, nor otherwise affect the rights, obligations and liabilities of the parties hereto or any of them. No Certificateholder shall have any right to vote (except as expressly 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 Person by reason of any action taken by the parties to this Agreement pursuant to any provision hereof. No Certificateholder shall have any right by virtue of any provision of this Agreement to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Agreement, unless such Holder previously shall have given to the Trustee a written notice of default and of the continuance thereof, as hereinbefore provided, and the Holders of Certificates of any Class evidencing in the aggregate 104 not less than 25% of the Percentage Interests of such Class shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder (in the case of conflicting requests by two or more 25% or greater Percentage Interests, the Trustee shall act in accordance with the first such request) and shall have offered to the Trustee such reasonable indemnity as it may require against the costs, expenses and liabilities to be incurred therein or thereby, and the Trustee, for sixty (60) days after its receipt of such notice, request and offer of indemnity, shall have neglected or refused to institute any such action, suit or proceeding; it being understood and intended, and being expressly covenanted by each Certificateholder with every other Certificateholder and the Trustee, that no one or more Holders of Certificates of any Class shall have any right in any manner whatever by virtue of any provision of this Agreement to affect, disturb or prejudice the rights of the Holders of any other of such Certificates of such Class or any other Class, 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 Certificateholders of such Class or all Classes, as the case may be.

Notwithstanding anything to the contrary in this Agreement, this Agreement may be amended from time to time by the Depositor, the Servicer and the Trustee with the consent of Certificateholders evidencing not less than 66-2/3% of the interests held by parties other than the Depositor, its Affiliates or its agents, for the purposes of significantly changing the Permitted Activities of the Trust. Promptly after the execution of any such amendment 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 12.03 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 105 prescribe.

The Agreement may also be amended from time to time by the Depositor, the Servicer and the Trustee with the consent of the Holders of Certificates evidencing in the aggregate not less than 66-2/3% of the Percentage Interests of each Class of Certificates affected thereby for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no such amendment may (i) reduce in any manner the amount of, or delay the timing of, payments received on Mortgage Loans which are required to be distributed on any Certificate without the consent of the Holder of such Certificate, (ii) reduce the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment or (iii) change the percentage specified in clause (ii) of the first paragraph of Section 11.01 of the Agreement, without the consent of the Holders of all Certificates of such Class then outstanding.

In addition to the foregoing, the Company shall provide to the Purchaser such information as the Purchaser may reasonably request concerning each Mortgage Loan that is at least sixty days delinquent and each Mortgage Loan which has become real estate owned, through the final liquidation thereof; provided that the Company shall only be required to provide information that is readily accessible to its servicing personnel and is non-confidential. (a) With respect to all Mortgage Loans which are serviced at any time by the Company through a Subservicer, the Company shall be entitled to rely for all purposes hereunder, including for purposes of fulfilling its reporting obligations under this Section 2.01 on the accuracy and completeness of any information provided to it by the applicable Subservicer. Section 2.02 Purchaser's Election to Delay Foreclosure Proceedings. 1. The Purchaser directs the Company that in the event that the Company does not receive written notice of the Purchaser's election pursuant to subsection (b) below within 24 hours (exclusive of any intervening non-Business Days) of transmission of the notice provided by the Company under Section 2.01(a)(ii), subject to extension as set forth in Section 2.02(b), the Company shall proceed with the Commencement of Foreclosure in respect of such Mortgage Loan in accordance with its normal foreclosure policies without further notice to the Purchaser. Any foreclosure that has been initiated may be discontinued (i) without notice to the Purchaser, if the Mortgage Loan has been brought current or if a refinancing or prepayment occurs with respect to the Mortgage Loan (including by means of a short payoff approved by the Company) (ii) with notice to the Purchaser if the Company has reached the terms of a forbearance agreement with the borrower. In such latter case the Company may complete such J-3 forbearance agreement unless instructed otherwise by the Purchaser within one Business Day of notification. 2. In connection with any Mortgage Loan with respect to which a notice under Section 2.01(a)(ii) has been given to the Purchaser, the Purchaser may elect, for reasonable cause as determined by the Purchaser, to instruct the Company to delay the Commencement of Foreclosure until such term as the Purchaser determines that the Company may proceed with the Commencement of Foreclosure. Such election must be evidenced by written notice received within 24 hours (exclusive of any intervening non-Business Days) of transmission of the notice provided by the Company under Section 2.01(a)(ii). Such 24 hour period shall be extended for no longer than an additional four Business Days after the receipt of the information if the Purchaser requests additional information related to such foreclosure; provided, however that the Purchaser will have at least one Business Day to respond to any requested additional information. Any such additional information shall (i) not be confidential in nature and (ii) be obtainable by the Company from existing reports, certificates or statements or otherwise be readily accessible to its servicing personnel. The Purchaser agrees that it has no right to deal with the Mortgagor. If the Company's normal foreclosure policy includes acceptance of a deed-in-lieu of foreclosure or short payoff, the Purchaser will be notified and given one Business Day to respond. 3. With respect to any Mortgage Loan as to which the Purchaser has made an Election to Delay Foreclosure, the Purchaser shall obtain a Current Appraisal as soon as practicable, and shall provide the Company with a copy of such Current Appraisal. 4. Within two Business Days of making any Election to Delay Foreclosure, the Purchaser shall remit by wire transfer to the Company, for deposit in the Collateral Fund, an amount, as calculated by the Company, equal to the sum of (i) 125% of the greater of the outstanding Principal Balance of the Mortgage Loan and the value shown in the Current Appraisal referred to in subsection (c) above (or, if such Current Appraisal has not yet been obtained, the Company's estimate thereof, in which case the required deposit under this subsection shall be adjusted upon obtaining of such Current Appraisal), and (ii) three months' interest on the Mortgage Loan at the applicable Mortgage Rate. If any Election to Delay Foreclosure extends for a period in excess of three months (such excess period being referred to herein as the "Excess Period"), the Purchaser shall remit by wire transfer in advance to the Company for deposit in the Collateral Fund the amount, as calculated by the Company, equal to interest on the Mortgage Loan at the applicable Mortgage Rate for the Excess Period. The terms of this Agreement shall no longer apply to the servicing of any Mortgage Loan upon the failure of the Purchaser to deposit the above amounts relating to the Mortgage Loan within two Business Days of the Election to Delay Foreclosure. 5. With respect to any Mortgage Loan as to which the Purchaser has made an Election to Delay Foreclosure, the Company may withdraw from the Collateral Fund from time to time amounts necessary to reimburse the Company for all Advances and Liquidation Expenses thereafter made by the Company as Servicer in accordance with the Pooling and Servicing Agreement. To the extent that the amount of any such Liquidation Expense is determined by the Company based on estimated costs, and the actual costs are subsequently determined to be higher, the Company may withdraw the additional amount from the Collateral Fund. In the event that the Mortgage Loan is brought current by the Mortgagor and the foreclosure action is discontinued, the amounts so withdrawn from the Collateral Fund shall be redeposited therein as and to the extent that reimbursement therefor from amounts paid by the Mortgagor is not prohibited pursuant to the Pooling and Servicing Agreement. Except as provided in the preceding sentence, amounts withdrawn from the Collateral Fund to cover Advances and Liquidation Expenses shall not be redeposited therein or otherwise reimbursed to the Purchaser. If and when any such Mortgage Loan is brought current by the Mortgagor, all amounts remaining in the Collateral Fund in respect of such J-4 Mortgage Loan (after adjustment for all withdrawals and deposits pursuant to this subsection) shall be released to the Purchaser. 6. With respect to any Mortgage Loan as to which the Purchaser has made an Election to Delay Foreclosure, the Company shall continue to service the Mortgage Loan in accordance with its customary procedures (other than the delay in Commencement of Foreclosure as provided herein). If and when the Purchaser shall notify the Company that it believes that it is appropriate to do so, the Company shall proceed with the Commencement of Foreclosure. In any event, if the Mortgage Loan is not brought current by the Mortgagor by the time the loan becomes 6 months delinquent, the Purchaser's election shall no longer be effective and at the Purchaser's option, either (i) the Purchaser shall purchase the Mortgage Loan from the Trust Fund at a purchase price equal to the fair market value as shown on the Current Appraisal, to be paid by (x) applying any balance in the Collateral Fund to such purchase price, and (y) to the extent of any deficiency, by wire transfer of immediately available funds to the Company or Trustee; or (ii) the Company shall proceed with the Commencement of Foreclosure. 7. Upon the occurrence of a liquidation with respect to any Mortgage Loan as to which the Purchaser made an Election to Delay Foreclosure and as to which the Company proceeded with the Commencement of Foreclosure in accordance with subsection (f) above, the Company shall calculate the amount, if any, by which the value shown on the Current Appraisal obtained under subsection (c) exceeds the actual sales price obtained for the related Mortgaged Property (or stock allocated to a dwelling unit in the case of a Co-op Loan) (net of Liquidation Expenses and accrued interest related to the extended foreclosure period), and the Company shall withdraw the amount of such excess from the Collateral Fund, shall remit the same to the Trust Fund and in its capacity as Servicer shall apply such amount as additional Liquidation Proceeds pursuant to the Pooling and Servicing Agreement. After making such withdrawal, all amounts remaining in the Collateral Fund in respect of such Mortgage Loan (after adjustment for all withdrawals and deposits pursuant to subsection (e)) shall be released to the Purchaser. Section 2.03 Purchaser's Election to Commence Foreclosure Proceedings. 1. In connection with any Mortgage Loan identified in a report under Section 2.01(a)(i)(B), the Purchaser may elect, for reasonable cause as determined by the Purchaser, to instruct the Company to proceed with the Commencement of Foreclosure as soon as practicable. Such election must be evidenced by written notice received by the Company by 5:00 p.m., New York City time, on the third Business Day following the delivery of such report under Section 2.01(a)(i). 2. Within two Business Days of making any Election to Foreclose, the Purchaser shall remit to the Company, for deposit in the Collateral Fund, an amount, as calculated by the Company, equal to 125% of the current Principal Balance of the Mortgage Loan and three months' interest on the Mortgage Loan at the applicable Mortgage Rate. If and when any such Mortgage Loan is brought current by the Mortgagor, all amounts in the Collateral Fund in respect of such Mortgage Loan shall be released to the Purchaser. The terms of this Agreement shall no longer apply to the servicing of any Mortgage Loan upon the failure of the Purchaser to deposit the above amounts relating to the Mortgage Loans within two Business Days at the Election to Foreclose. 3. With respect to any Mortgage Loan as to which the Purchaser has made an Election to Foreclose, the Company shall continue to service the Mortgage Loan in accordance with its customary procedures (other than to proceed with the Commencement of Foreclosure as provided herein). In connection therewith, the Company shall have the same rights to make withdrawals for Advances and Liquidation Expenses from the Collateral Fund as are provided under Section 2.02(e), and the Company shall make reimbursements thereto to the limited extent provided under such subsection. The Company shall not be required to proceed with the Commencement of Foreclosure if (i) the same is stayed as a result of the Mortgagor's bankruptcy or is otherwise barred by applicable law, or to the extent that all J-5 legal conditions precedent thereto have not yet been complied with or (ii) the Company believes there is a breach of representation or warranties by the Company, which may result in a repurchase or substitution of such Mortgage Loan, or (iii) the Company reasonably believes the Mortgaged Property (or Underlying Mortgaged Property, in the case of a Co-op Loan) may be contaminated with or affected by hazardous wastes or hazardous substances (and the Company supplies the Purchaser with information supporting such belief). The Company will repurchase or substitute a Mortgage Loan pursuant to the preceding clause (ii) within the time period specified in the Pooling and Servicing Agreement. Any foreclosure that has been initiated may be discontinued (i) without notice to the Purchaser if the Mortgage Loan has been brought current or if a refinancing or prepayment occurs with respect to the Mortgage Loan (including by means of a short payoff approved by the Company), or (ii) with notice to the Purchaser if the Company has reached the terms of a forbearance agreement unless instructed otherwise by the Purchaser within two Business Days of notification. 4. Upon the occurrence of a liquidation with respect to any Mortgage Loan as to which the Purchaser made an Election to Foreclose and as to which the Company proceeded with the Commencement of Foreclosure in accordance with subsection (c) above, the Company shall calculate the amount, if any, by which the Principal Balance of the Mortgage Loan at the time of liquidation (plus all unreimbursed Advances and Liquidation Expenses in connection therewith other than those paid from the Collateral Fund) exceeds the actual sales price obtained for the related Mortgaged Property (or stock allocated to a dwelling unit in the case of a Co-op Loan), and the Company shall withdraw the amount of such excess from the Collateral Fund, shall remit the same to the Trust Fund and in its capacity as Servicer shall apply such amount as additional Liquidation Proceeds pursuant to the Pooling and Servicing Agreement. After making such withdrawal, all amounts remaining in the Collateral Fund (after adjustment for all withdrawals and deposits pursuant to subsection (c)) in respect of such Mortgage Loan shall be released to the Purchaser. Section 2.04 Termination. 1.
