In the event that any such original document is required pursuant to the terms of this Section 2.01 to be a part of a Mortgage File, such document shall be delivered promptly to the Trustee. Any such original document delivered to or held by the Depositor that is not required pursuant to the terms of this Section to be a part of a Mortgage File, shall be delivered promptly to the Master Servicer. SECTION 2.02. Acceptance of REMIC I by Trustee. The Trustee acknowledges receipt, subject to the provisions of Section 2.01 and subject to any exceptions noted on the exception report described in the next paragraph below, the documents referred to in Section 2.01 (other than such documents described in Section 2.01(v)) above and all other assets included in the definition of "REMIC I" under clauses (i), (iii), (iv) and (v) (to the extent of amounts deposited into the Distribution Account) and declares that it holds and will hold such documents and the other documents delivered to it constituting a Mortgage File, and that it holds or will hold all such assets and such other assets included in the definition of "REMIC I" in trust for the exclusive use and benefit of all present and future Certificateholders. The Trustee agrees to execute and deliver to the Depositor and the NIMS Insurer on or prior to the Closing Date an acknowledgment of receipt of the original Mortgage Note (with any exceptions noted), substantially in the form attached as Exhibit C-3 hereto. The Trustee agrees, for the benefit of the Certificateholders and the NIMS Insurer, to review each Mortgage File and, within 45 days of the Closing Date, to certify in substantially the form attached hereto as Exhibit C-1 that, as to each Mortgage Loan listed in the Mortgage Loan Schedule (other than any Mortgage Loan paid in full or any Mortgage Loan specifically identified in the exception report annexed thereto as not being covered by such certification), (i) all documents constituting part of such Mortgage File (other than such documents described in Section 2.01(v)) required to be delivered to it pursuant to this Agreement are in its possession, (ii) such documents have been reviewed by the Trustee and appear regular on their face and relate to such Mortgage Loan and (iii) based on the Trustee's examination and only as to the foregoing, the information set forth in the Mortgage Loan Schedule that corresponds to items (1), (2), (3), (12), (15) and (18) of the -51- definition of "Mortgage Loan Schedule" accurately reflects information set forth in the Mortgage File. It is herein acknowledged that, in conducting such review, the Trustee is under no duty or obligation (i) to inspect, review or examine any such documents, instruments, certificates or other papers to determine whether they are genuine, enforceable, or appropriate for the represented purpose or whether they have actually been recorded or that they are other than what they purport to be on their face or (ii) to determine whether any Mortgage File should include any of the documents specified in clause (v) of Section 2.01. Prior to the first anniversary date of this Agreement the Trustee shall deliver to the Depositor, the NIMS Insurer and the Master Servicer a final certification in the form annexed hereto as Exhibit C-2 evidencing the completeness of the Mortgage Files, with any applicable exceptions noted thereon, and the Master Servicer shall forward a copy thereof to any Sub-Servicer. If in the process of reviewing the Mortgage Files and making or preparing, as the case may be, the certifications referred to above, the Trustee finds any document or documents constituting a part of a Mortgage File to be missing or defective in any material respect, at the conclusion of its review the Trustee shall so notify the Depositor, the NIMS Insurer and the Master Servicer. In addition, upon the discovery by the Depositor, the NIMS Insurer, the Master Servicer or the Trustee of a breach of any of the representations and warranties made by the Originator or the Seller in the Mortgage Loan Purchase Agreement in respect of any Mortgage Loan which materially adversely affects such Mortgage Loan or the interests of the related Certificateholders in such Mortgage Loan, the party discovering such breach shall give prompt written notice to the other parties. The Trustee shall, at the written request and expense of any Certificateholder, provide a written report to such Certificateholder of all Mortgage Files released to the Master Servicer for servicing purposes. The Depositor and the Trustee intend that the assignment and transfer herein contemplated constitute a sale of the Mortgage Loans, the related Mortgage Notes and the related documents, conveying good title thereto free and clear of any liens and encumbrances, from the Depositor to the Trustee in trust for the benefit of the Certificateholders and that such property not be part of the Depositor's estate or property of the Depositor in the event of any insolvency by the Depositor. In the event that such conveyance is deemed to be, or to be made as security for, a loan, the parties intend that the Depositor shall be deemed to have granted and does hereby grant to the Trustee a first priority perfected security interest in all of the Depositor's right, title and interest in and to the Mortgage Loans, the related Mortgage Notes and the related documents, and that this Agreement shall constitute a security agreement under applicable law. SECTION 2.03. Repurchase or Substitution of Mortgage Loans by the Originator or the Seller. (a) Upon discovery or receipt of notice of any materially defective document in, or that a document is missing from, a Mortgage File or of the breach by the Originator or the Seller of any representation, warranty or covenant under the Mortgage Loan Purchase Agreement (including any representation, warranty or covenant regarding the Prepayment Charge Schedule) in -52- respect of any Mortgage Loan that materially adversely affects the value of such Mortgage Loan or the interest therein of the Certificateholders, the Trustee shall promptly notify the Originator, the NIMS Insurer, the Seller and the Master Servicer of such defect, missing document or breach and request that the Originator or the Seller, as applicable, deliver such missing document or cure such defect or breach within 90 days from the date the Originator or the Seller, as applicable, was notified of such missing document, defect or breach, and if the Originator or the Seller, as applicable, does not deliver such missing document or cure such defect or breach in all material respects during such period, the Master Servicer, to the extent it is not the Originator, the Seller or an Affiliate of the Seller, and otherwise the Trustee, in accordance with Section 3.02(b), shall enforce the obligations of the Originator or the Seller, as applicable, under the Mortgage Loan Purchase Agreement to repurchase such Mortgage Loan from REMIC I at the Purchase Price within 90 days after the date on which the Originator or the Seller, as applicable, was notified (subject to Section 2.03(c)) of such missing document, defect or breach, if and to the extent that the Originator or the Seller, as applicable, is obligated to do so under the Mortgage Loan Purchase Agreement. The Purchase Price for the repurchased Mortgage Loan shall be remitted to the Master Servicer for deposit in the Collection Account and the Trustee, upon receipt of written certification from the Master Servicer of such deposit, shall release to the Originator or the Seller, as applicable, the related Mortgage File and the Trustee shall execute and deliver such instruments of transfer or assignment, in each case without recourse, as the Originator or the Seller, as applicable, shall furnish to it and as shall be necessary to vest in the Originator or the Seller, as applicable, any Mortgage Loan released pursuant hereto. The Trustee shall not have any further responsibility with regard to such Mortgage File. In lieu of repurchasing any such Mortgage Loan as provided above, if so provided in the Mortgage Loan Purchase Agreement, the Originator or the Seller, as applicable, may cause such Mortgage Loan to be removed from REMIC I (in which case it shall become a Deleted Mortgage Loan) and substitute one or more Qualified Substitute Mortgage Loans in the manner and subject to the limitations set forth in Section 2.03(b). It is understood and agreed that the obligation of the Originator or the Seller, as applicable, to cure or to repurchase (or to substitute for) any Mortgage Loan as to which a document is missing, a material defect in a constituent document exists or as to which such a breach has occurred and is continuing shall constitute the sole remedy respecting such omission, defect or breach available to the Trustee and the Certificateholders. (b) Any substitution of Qualified Substitute Mortgage Loans for Deleted Mortgage Loans made pursuant to Section 2.03(a) must be effected prior to the date which is two years after the Startup Day for REMIC I. As to any Deleted Mortgage Loan for which the Originator or the Seller, as applicable, substitutes a Qualified Substitute Mortgage Loan or Loans, such substitution shall be effected by the Originator or the Seller, as applicable, delivering to the Trustee, for such Qualified Substitute Mortgage Loan or Loans, the Mortgage Note, the Mortgage, the Assignment to the Trustee, and such other documents and agreements, with all necessary endorsements thereon, as are required by Section 2.01, together with an Officers' Certificate providing that each such Qualified Substitute Mortgage Loan satisfies the definition thereof and specifying the Substitution Adjustment Amount (as described below), if any, in connection with such substitution. The Trustee shall acknowledge receipt for such Qualified Substitute Mortgage Loan or Loans and, within ten Business Days thereafter, review such documents as specified in Section 2.02 and deliver to the Depositor, the NIMS Insurer and the Master Servicer, with respect to such Qualified Substitute Mortgage Loan -53- or Loans, a certification substantially in the form attached hereto as Exhibit C-1, with any applicable exceptions noted thereon. Within one year of the date of substitution, the Trustee shall deliver to the Depositor, the NIMS Insurer and the Master Servicer a certification substantially in the form of Exhibit C-2 hereto with respect to such Qualified Substitute Mortgage Loan or Loans, with any applicable exceptions noted thereon. Monthly Payments due with respect to Qualified Substitute Mortgage Loans in the month of substitution are not part of REMIC I and will be retained by the Originator or the Seller, as applicable,. For the month of substitution, distributions to Certificateholders will reflect the Monthly Payment due on such Deleted Mortgage Loan on or before the Due Date in the month of substitution, and the Originator or the Seller, as applicable, shall thereafter be entitled to retain all amounts subsequently received in respect of such Deleted Mortgage Loan. The Depositor shall give or cause to be given written notice to the Certificateholders and the NIMS Insurer that such substitution has taken place, shall amend the Mortgage Loan Schedule to reflect the removal of such Deleted Mortgage Loan from the terms of this Agreement and the substitution of the Qualified Substitute Mortgage Loan or Loans and shall deliver a copy of such amended Mortgage Loan Schedule to the Trustee and the NIMS Insurer. Upon such substitution, such Qualified Substitute Mortgage Loan or Loans shall constitute part of the Mortgage Pool and shall be subject in all respects to the terms of this Agreement and the Mortgage Loan Purchase Agreement, including, all applicable representations and warranties thereof included in the Mortgage Loan Purchase Agreement. For any month in which the Originator or the Seller, as applicable, substitutes one or more Qualified Substitute Mortgage Loans for one or more Deleted Mortgage Loans, the Master Servicer will determine the amount (the "Substitution Adjustment Amount"), if any, by which the aggregate Purchase Price of all such Deleted Mortgage Loans exceeds the aggregate of, as to each such Qualified Substitute Mortgage Loan, the Principal Balance thereof as of the date of substitution, together with one month's interest on such Principal Balance at the applicable Net Mortgage Rate, plus all outstanding Advances and Servicing Advances (including Nonrecoverable Advances and Nonrecoverable Servicing Advances) related thereto. On the date of such substitution, the Originator or the Seller, as applicable, will deliver or cause to be delivered to the Master Servicer for deposit in the Collection Account an amount equal to the Substitution Adjustment Amount, if any, and the Trustee, upon receipt of the related Qualified Substitute Mortgage Loan or Loans and certification by the Master Servicer of such deposit, shall release to the Originator or the Seller, as applicable, the related Mortgage File or Files and the Trustee shall execute and deliver such instruments of transfer or assignment, in each case without recourse, the Originator or the Seller, as applicable, shall deliver to it and as shall be necessary to vest therein any Deleted Mortgage Loan released pursuant hereto. In addition, the Originator or the Seller, as applicable, shall obtain at its own expense and deliver to the Trustee and the NIMS Insurer an Opinion of Counsel to the effect that such substitution will not cause (a) any federal tax to be imposed on any Trust REMIC, including without limitation, any federal tax imposed on "prohibited transactions" under Section 860F(a)(1) of the Code or on "contributions after the startup date" under Section 860G(d)(1) of the Code, or (b) any Trust REMIC to fail to qualify as a REMIC at any time that any Certificate is outstanding. (c) Upon discovery by the Depositor, the NIMS Insurer, the Originator, the Seller, the Master Servicer or the Trustee that any Mortgage Loan does not constitute a "qualified mortgage" within the meaning of Section 860G(a)(3) of the Code, the party discovering such fact -54- shall within two Business Days give written notice thereof to the other parties. In connection therewith, the Originator, the Seller or the Depositor shall repurchase or, subject to the limitations set forth in Section 2.03(b), substitute one or more Qualified Substitute Mortgage Loans for the affected Mortgage Loan within 90 days of the earlier of discovery or receipt of such notice with respect to such affected Mortgage Loan. Such repurchase or substitution shall be made by (i) the Originator or the Seller, as the case may be, if the affected Mortgage Loan's status as a non-qualified mortgage is or results from a breach of any representation, warranty or covenant made by the Originator or the Seller, as the case may be, under the Mortgage Loan Purchase Agreement, or (ii) the Depositor, if the affected Mortgage Loan's status as a non-qualified mortgage is a breach of no representation or warranty. Any such repurchase or substitution shall be made in the same manner as set forth in Section 2.03(a). The Trustee shall reconvey to the Depositor, the Originator or the Seller, as the case may be, the Mortgage Loan to be released pursuant hereto in the same manner, and on the same terms and conditions, as it would a Mortgage Loan repurchased for breach of a representation or warranty.

To the extent consistent with the foregoing, the Master Servicer (a) shall seek the timely and complete recovery of principal and interest on the Mortgage Notes and (b) shall waive (or permit a Sub-Servicer to waive) a Prepayment Charge only under the following circumstances: (i) such waiver is standard and customary in servicing similar Mortgage Loans and (ii) either (A) such waiver relates to a default or a reasonably foreseeable default and would, in the reasonable judgment of the Master Servicer, maximize recovery of total proceeds taking into account the value of such Prepayment Charge and the related Mortgage Loan or (B) such waiver is made in connection with a refinancing of the related Mortgage Loan unrelated to a default or a reasonably foreseeable default where (x) the related mortgagor has stated to the Master Servicer or an applicable Sub- Servicer an intention to refinance the related Mortgage Loan and (y) the Master Servicer has concluded in its reasonable judgement that the waiver of such Prepayment Charge would induce such mortgagor to refinance with the Master Servicer; provided, however, that the Master Servicer shall waive no more than 5.00% of the Prepayment Charges (by number of Prepayment Charges) set forth on the Prepayment Charge Schedule in accordance with clause (ii)(B) above. If a Prepayment Charge is waived as permitted by meeting the standards described in clauses (i) and (ii)(B) above, then the Master Servicer is required to pay the amount of such waived Prepayment Charge, for the benefit of the Holders of the Class P Certificates, by depositing such amount into the Collection Account together with and at the time that the amount prepaid on the related Mortgage Loan is required to be deposited into the Collection Account. Notwithstanding any other provisions -59- of this Agreement, any payments made by the Master Servicer in respect of any waived Prepayment Charges pursuant to clauses (i) and (ii)(B) above shall be deemed to be paid outside of the Trust Fund. Subject only to the above-described servicing standards and the terms of this Agreement and of the Mortgage Loans, the Master Servicer shall have full power and authority, acting alone or through Sub-Servicers as provided in Section 3.02, to do or cause to be done any and all things in connection with such servicing and administration which it may deem necessary or desirable. Without limiting the generality of the foregoing, the Master Servicer in its own name or in the name of a Sub-Servicer is hereby authorized and empowered by the Trustee when the Master Servicer believes it appropriate in its best judgment in accordance with the servicing standards set forth above, to execute and deliver, on behalf of the Certificateholders and the Trustee, and upon notice to the Trustee, 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 the Mortgaged Properties and to institute foreclosure proceedings or obtain a deed-in-lieu of foreclosure so as to convert the ownership of such properties, and to hold or cause to be held title to such properties, on behalf of the Trustee and Certificateholders. The Master Servicer shall service and administer the Mortgage Loans in accordance with applicable state and federal law and shall provide to the Mortgagors any reports required to be provided to them thereby. The Master Servicer shall also comply in the performance of this Agreement with all reasonable rules and requirements of each insurer under any standard hazard insurance policy. Subject to Section 3.17, within 15 days of the Closing Date, the Trustee shall execute, at the written request of the Master Servicer, and furnish to the Master Servicer and any Sub-Servicer any special or limited powers of attorney for each county in which a Mortgaged Property is located and other documents necessary or appropriate to enable the Master Servicer or any Sub-Servicer to carry out their servicing and administrative duties hereunder; provided, such limited powers of attorney or other documents shall be prepared by the Master Servicer and submitted to the Trustee for execution. The Trustee shall not be liable for the actions of the Master Servicer or any Sub-Servicers under such powers of attorney. Subject to Section 3.09 hereof, in accordance with the standards of the preceding paragraph, the Master Servicer shall advance or cause to be advanced funds as necessary for the purpose of effecting the timely payment of taxes and assessments on the Mortgaged Properties, which advances shall be Servicing Advances reimbursable in the first instance from related collections from the Mortgagors pursuant to Section 3.09, and further as provided in Section 3.11. Any cost incurred by the Master Servicer or by Sub-Servicers in effecting the timely payment of taxes and assessments on a Mortgaged Property shall not, for the purpose of calculating distributions to Certificateholders, be added to the unpaid Principal Balance of the related Mortgage Loan, notwithstanding that the terms of such Mortgage Loan so permit. Notwithstanding anything in this Agreement to the contrary, the Master Servicer may not make any future advances with respect to a Mortgage Loan (except as provided in Section 4.03) and the Master Servicer shall not (i) permit any modification with respect to any Mortgage Loan that would change the Mortgage Rate, reduce or increase the Principal Balance (except for reductions resulting from actual payments of principal) or change the final maturity date on such Mortgage Loan (unless, as provided in Section 3.07, the Mortgagor is in default with respect to the Mortgage Loan or such default is, in the judgment of the Master Servicer, reasonably foreseeable) or (ii) permit any modification, waiver or amendment of any term of any Mortgage Loan that would both (A) effect an exchange or reissuance of such Mortgage Loan under Section 1001 of the Code (or -60- Treasury regulations promulgated thereunder) and (B) cause any REMIC created hereunder to fail to qualify as a REMIC under the Code or the imposition of any tax on "prohibited transactions" or "contributions after the startup date" under the REMIC Provisions. SECTION 3.02. Sub-Servicing Agreements Between Master Servicer and Sub-Servicers. (a) The Master Servicer may enter into Sub-Servicing Agreements with Sub- Servicers for the servicing and administration of the Mortgage Loans; provided, however, that (i) such agreements would not result in a withdrawal or a downgrading by any Rating Agency of the rating on any Class of Certificates and (ii) the NIMS Insurer shall have consented to such Sub- Servicing Agreement. The Trustee is hereby authorized to acknowledge, at the request of the Master Servicer, any Sub-Servicing Agreement that meets the requirements applicable to Sub-Servicing Agreements set forth in this Agreement and that is otherwise permitted under this Agreement. Each Sub-Servicer shall be (i) authorized to transact business in the state or states where the related Mortgaged Properties it is to service are situated, if and to the extent required by applicable law to enable the Sub-Servicer to perform its obligations hereunder and under the Sub- Servicing Agreement and (ii) a Freddie Mac or Fannie Mae approved mortgage servicer. Each Sub- Servicing Agreement must impose on the Sub-Servicer requirements conforming to the provisions set forth in Section 3.08 and provide for servicing of the Mortgage Loans consistent with the terms of this Agreement. The Master Servicer will examine each Sub-Servicing Agreement and will be familiar with the terms thereof. The terms of any Sub-Servicing Agreement will not be inconsistent with any of the provisions of this Agreement. The Master Servicer and the Sub-Servicers may enter into and make amendments to the Sub-Servicing Agreements or enter into different forms of Sub- Servicing Agreements; provided, however, that any such amendments or different forms shall be consistent with and not violate the provisions of this Agreement, and that no such amendment or different form shall be made or entered into which could be reasonably expected to be materially adverse to the interests of the Certificateholders without the consent of the Holders of Certificates entitled to at least 66% of the Voting Rights; provided, further, that the consent of the Holders of Certificates entitled to at least 66% of the Voting Rights shall not be required (i) to cure any ambiguity or defect in a Sub-Servicing Agreement, (ii) to correct, modify or supplement any provisions of a Sub-Servicing Agreement, or (iii) to make any other provisions with respect to matters or questions arising under a Sub-Servicing Agreement, which, in each case, shall not be inconsistent with the provisions of this Agreement. Any variation without the consent of the Holders of Certificates entitled to at least 66% of the Voting Rights from the provisions set forth in Section 3.08 relating to insurance or priority requirements of Sub-Servicing Accounts, or credits and charges to the Sub-Servicing Accounts or the timing and amount of remittances by the Sub-Servicers to the Master Servicer, are conclusively deemed to be inconsistent with this Agreement and therefore prohibited. The Master Servicer shall deliver to the NIMS Insurer and the Trustee copies of all Sub- Servicing Agreements, and any amendments or modifications thereof, promptly upon the Master Servicer's execution and delivery of such instruments. (b) As part of its servicing activities hereunder, the Master Servicer, for the benefit of the Trustee and the Certificateholders, shall enforce the obligations of each Sub-Servicer under the related Sub-Servicing Agreement and of the Originator and the Seller under the Mortgage -61- Loan Purchase Agreement, including, without limitation, any obligation to make advances in respect of delinquent payments as required by a Sub-Servicing Agreement, or to purchase a Mortgage Loan on account of missing or defective documentation or on account of a breach of a representation, warranty or covenant, as described in Section 2.03(a). Such enforcement, including, without limitation, the legal prosecution of claims, termination of Sub-Servicing Agreements, and the pursuit of other appropriate remedies, shall be in such form and carried out to such an extent and at such time as the Master Servicer, in its good faith business judgment, would require were it the owner of the related Mortgage Loans. The Master Servicer shall pay the costs of such enforcement at its own expense, and shall be reimbursed therefor only (i) from a general recovery resulting from such enforcement, 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. Enforcement of the Mortgage Loan Purchase Agreement against the Originator or the Seller shall be effected by the Master Servicer to the extent it is not the Originator, and otherwise by the Trustee in accordance with the foregoing provisions of this paragraph. SECTION 3.03. Successor Sub-Servicers. The Master Servicer, with the consent of the NIMS Insurer, shall be entitled to terminate any Sub-Servicing Agreement and the rights and obligations of any Sub-Servicer pursuant to any Sub-Servicing Agreement in accordance with the terms and conditions of such Sub-Servicing Agreement. In the event of termination of any Sub-Servicer, all servicing obligations of such Sub- Servicer shall be assumed simultaneously by the Master Servicer without any act or deed on the part of such Sub-Servicer or the Master Servicer, and the Master Servicer either shall service directly the related Mortgage Loans or shall enter into a Sub-Servicing Agreement with a successor Sub-Servicer which qualifies under Section 3.02. Any Sub-Servicing Agreement shall include the provision that such agreement may be immediately terminated by the Trustee (if the Trustee is acting as Master Servicer) without fee, in accordance with the terms of this Agreement, in the event that the Master Servicer (or the Trustee, if such party is then acting as Master Servicer) shall, for any reason, no longer be the Master Servicer (including termination due to a Master Servicer Event of Termination). SECTION 3.04. Liability of the Master Servicer. Notwithstanding any Sub-Servicing Agreement or the provisions of this Agreement relating to agreements or arrangements between the Master Servicer and a Sub-Servicer or reference to actions taken through a Sub-Servicer or otherwise, the Master Servicer shall remain obligated and primarily liable to the Trustee and the Certificateholders for the servicing and administering of the Mortgage Loans in accordance with the provisions of Section 3.01 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 Master Servicer alone were servicing and administering the Mortgage Loans. The Master Servicer shall be entitled to enter into any agreement with a Sub-Servicer for indemnification of the Master Servicer by such Sub-Servicer and nothing contained in this Agreement shall be deemed to limit or modify such indemnification. -62- SECTION 3.05. No Contractual Relationship Between Sub-Servicers and the NIMS Insurer, the Trustee or Certificateholders. Any Sub-Servicing Agreement that may be entered into and any transactions or services relating to the Mortgage Loans involving a Sub-Servicer in its capacity as such shall be deemed to be between the Sub-Servicer and the Master Servicer alone, and the NIMS Insurer, the Trustee or Certificateholders shall not be deemed parties thereto and shall have no claims, rights, obligations, duties or liabilities with respect to the Sub-Servicer except as set forth in Section 3.06. The Master Servicer shall be solely liable for all fees owed by it to any Sub-Servicer, irrespective of whether the Master Servicer's compensation pursuant to this Agreement is sufficient to pay such fees. SECTION 3.06. Assumption or Termination of Sub-Servicing Agreements by Trustee. In the event the Master Servicer shall for any reason no longer be the servicer (including by reason of the occurrence of a Master Servicer Event of Termination), the Trustee shall thereupon assume all of the rights and obligations of the Master Servicer under each Sub-Servicing Agreement that the Master Servicer may have entered into, unless the Trustee elects to terminate any Sub-Servicing Agreement in accordance with its terms as provided in Section 3.03. Upon such assumption, the Trustee (or the successor servicer appointed pursuant to Section 7.02) shall be deemed, subject to Section 3.03, to have assumed all of the departing Master Servicer's interest therein and to have replaced the departing Master Servicer as a party to each Sub-Servicing Agreement to the same extent as if each Sub-Servicing Agreement had been assigned to the assuming party, except that (i) the departing Master Servicer shall not thereby be relieved of any liability or obligations under any Sub-Servicing Agreement that arose before it ceased to be the Master Servicer and (ii) neither the Trustee nor any successor Master Servicer shall be deemed to have assumed any liability or obligation of the Master Servicer that arose before it ceased to be the Master Servicer. The Master Servicer at its expense shall, upon request of Trustee, deliver to the assuming party all documents and records relating to each Sub-Servicing Agreement and the Mortgage Loans then being serviced and an accounting of amounts collected and held by or on behalf of it, and otherwise use its best efforts to effect the orderly and efficient transfer of the Sub- Servicing Agreements to the assuming party. All Servicing Transfer Costs shall be paid by the predecessor Master Servicer upon presentation of reasonable documentation of such costs, and if such predecessor Master Servicer defaults in its obligation to pay such costs, such costs shall be paid by the successor Master Servicer or the Trustee (in which case the successor Master Servicer or the Trustee, as applicable, shall be entitled to reimbursement therefor from the assets of the Trust Fund). SECTION 3.07. Collection of Certain Mortgage Loan Payments. The Master Servicer shall make reasonable efforts to collect all payments called for under the terms and provisions of the Mortgage Loans, and shall, to the extent such procedures shall be consistent with this Agreement and the terms and provisions of any applicable insurance policies, follow such collection procedures as it would follow with respect to mortgage loans comparable to -63- the Mortgage Loans and held for its own account. Consistent with the foregoing, the Master Servicer may in its discretion (i) waive any late payment charge or, if applicable, any penalty interest, or (ii) extend the due dates for the Monthly Payments due on a Mortgage Note for a period of not greater than 180 days; provided, however, that any extension pursuant to clause (ii) above shall not affect the amortization schedule of any Mortgage Loan for purposes of any computation hereunder, except as provided below; provided further that the NIMS Insurer's prior written consent shall be required for any modification, waiver or amendment if the amendment if the aggregate number of outstanding Mortgage Loans which have been modified, waived or amended exceeds 5% of the number of Mortgage Loans as of the Cut-off Date. In the event of any such arrangement pursuant to clause (ii) above, the Master Servicer shall make timely advances on such Mortgage Loan during such extension pursuant to Section 4.03 and in accordance with the amortization schedule of such Mortgage Loan without modification thereof by reason of such arrangement. Notwithstanding the foregoing, in the event that any Mortgage Loan is in default or, in the judgment of the Master Servicer, such default is reasonably foreseeable, the Master Servicer, consistent with the standards set forth in Section 3.01, may also waive, modify or vary any term of such Mortgage Loan (including modifications that would change the Mortgage Rate, forgive the payment of principal or interest or extend the final maturity date of such Mortgage Loan), accept payment from the related Mortgagor of an amount less than the Stated Principal Balance in final satisfaction of such Mortgage Loan, or consent to the postponement of strict compliance with any such term or otherwise grant indulgence to any Mortgagor (any and all such waivers, modifications, variances, forgiveness of principal or interest, postponements, or indulgences collectively referred to herein as "forbearance"), provided, however, that in no event shall the Master Servicer grant any such forbearance (other than as permitted by the second sentence of this Section) with respect to any one Mortgage Loan more than once in any 12 month period or more than three times over the life of such Mortgage Loan, and provided, further, that in determining which course of action permitted by this sentence it shall pursue, the Master Servicer shall adhere to the Loss Mitigation Procedures. The Master Servicer's analysis supporting any forbearance and the conclusion that any forbearance meets the standards of Section 3.01 and the Loss Mitigation Procedures shall be reflected in writing in the Mortgage File. SECTION 3.08. Sub-Servicing Accounts. In those cases where a Sub-Servicer is servicing a Mortgage Loan pursuant to a Sub- Servicing Agreement, the Sub-Servicer will be required to establish and maintain one or more accounts (collectively, the "Sub-Servicing Account"). The Sub-Servicing Account shall be an Eligible Account and shall comply with all requirements of this Agreement relating to the Collection Account. The Sub-Servicer shall deposit in the clearing account in which it customarily deposits payments and collections on mortgage loans in connection with its mortgage loan servicing activities on a daily basis, and in no event more than one Business Day after the Sub-Servicer's receipt thereof, all proceeds of Mortgage Loans received by the Sub-Servicer less its servicing compensation to the extent permitted by the Sub-Servicing Agreement, and shall thereafter deposit such amounts in the Sub-Servicing Account, in no event more than two Business Days after the receipt of such amounts. The Sub-Servicer shall thereafter deposit such proceeds in the Collection Account or remit such proceeds to the Master Servicer for deposit in the Collection Account not later than two Business Days after the deposit of such amounts in the Sub-Servicing Account. For purposes of this Agreement, the Master Servicer shall be deemed to have received payments on the Mortgage Loans -64- when the Sub-Servicer receives such payments. SECTION 3.09. Collection of Taxes, Assessments and Similar Items; Servicing Accounts. The Master Servicer shall establish and maintain, or cause to be established and maintained, one or more accounts (the "Servicing Accounts"), into which all Escrow Payments shall be deposited and retained. Servicing Accounts shall be Eligible Accounts. The Master Servicer shall deposit in the clearing account in which it customarily deposits payments and collections on mortgage loans in connection with its mortgage loan servicing activities on a daily basis, and in no event more than one Business Day after the Master Servicer's receipt thereof, all Escrow Payments collected on account of the Mortgage Loans and shall thereafter deposit such Escrow Payments in the Servicing Accounts, in no event more than two Business Days after the receipt of such Escrow Payments, all Escrow Payments collected on account of the Mortgage Loans for the purpose of effecting the timely payment of any such items as required under the terms of this Agreement. Withdrawals of amounts from a Servicing Account may be made only to (i) effect payment of taxes, assessments, hazard insurance premiums, and comparable items in a manner and at a time that assures that the lien priority of the Mortgage is not jeopardized (or, with respect to the payment of taxes, in a manner and at a time that avoids the loss of the Mortgaged Property due to a tax sale or the foreclosure as a result of a tax lien); (ii) reimburse the Master Servicer (or a Sub-Servicer to the extent provided in the related Sub-Servicing Agreement) out of related collections for any Servicing Advances made pursuant to Section 3.01 (with respect to taxes and assessments) and Section 3.14 (with respect to hazard insurance); (iii) refund to Mortgagors any sums as may be determined to be overages; (iv) pay interest, if required and as described below, to Mortgagors on balances in the Servicing Account; or (v) clear and terminate the Servicing Account at the termination of the Master Servicer's obligations and responsibilities in respect of the Mortgage Loans under this Agreement in accordance with Article IX. In the event the Master Servicer shall deposit in a Servicing Account any amount not required to be deposited therein, it may at any time withdraw such amount from such Servicing Account, any provision herein to the contrary notwithstanding. The Master Servicer will be responsible for the administration of the Servicing Accounts and will be obligated to make Servicing Advances to such accounts when and as necessary to avoid the lapse of insurance coverage on the Mortgaged Property, or which the Master Servicer knows, or in the exercise of the required standard of care of the Master Servicer hereunder should know, is necessary to avoid the loss of the Mortgaged Property due to a tax sale or the foreclosure as a result of a tax lien. If any such payment has not been made and the Master Servicer receives notice of a tax lien with respect to the Mortgage being imposed, the Master Servicer will, within 10 business days of such notice, advance or cause to be advanced funds necessary to discharge such lien on the Mortgaged Property. As part of its servicing duties, the Master Servicer or Sub-Servicers shall pay to the Mortgagors interest on funds in the Servicing Accounts, to the extent required by law and, to the extent that interest earned on funds in the Servicing Accounts is insufficient, to pay such interest from its or their own funds, without any reimbursement therefor. The Master Servicer may pay to itself any excess interest on funds in the Servicing Accounts, to the extent such action is in conformity with the Servicing Standard, is permitted by law and such amounts are not required to be paid to Mortgagors or used for any of the other purposes set forth above. SECTION 3.10. Collection Account and Distribution Account. -65- (a) On behalf of the Trust Fund, the Master Servicer shall establish and maintain, or cause to be established and maintained, one or more accounts (such account or accounts, the "Collection Account"), held in trust for the benefit of the Trustee and the Certificateholders. On behalf of the Trust Fund, the Master Servicer shall deposit or cause to be deposited in the clearing account in which it customarily deposits payments and collections on mortgage loans in connection with its mortgage loan servicing activities on a daily basis, and in no event more than one Business Day after the Master Servicer's receipt thereof, and shall thereafter deposit in the Collection Account, in no event more than two Business Days after the Master Servicer's receipt thereof, as and when received or as otherwise required hereunder, the following payments and collections received or made by it subsequent to the Cut-off Date (other than in respect of principal or interest on the Mortgage Loans due on or before the Cut-off Date) or payments (other than Principal Prepayments) received by it on or prior to the Cut-off Date, but allocable to a Due Period subsequent thereto: (i) all payments on account of principal, including Principal Prepayments (but not Prepayment Charges), on the Mortgage Loans; (ii) all payments on account of interest (net of the related Servicing Fee) on each Mortgage Loan; (iii) all Insurance Proceeds, Liquidation Proceeds and condemnation proceeds (other than proceeds collected in respect of any particular REO Property and amounts paid in connection with a purchase of Mortgage Loans and REO Properties pursuant to Section 9.01); (iv) any amounts required to be deposited pursuant to Section 3.12 in connection with any losses realized on Permitted Investments with respect to funds held in the Collection Account; (v) any amounts required to be deposited by the Master Servicer pursuant to the second paragraph of Section 3.14(a) in respect of any blanket policy deductibles; (vi) all proceeds of any Mortgage Loan repurchased or purchased in accordance with Section 2.03 or Section 9.01; (vii) all amounts required to be deposited in connection with Substitution Adjustments pursuant to Section 2.03; (viii) all Prepayment Charges collected by the Master Servicer and any Master Servicer Prepayment Charge Payment Amounts in connection with the Principal Prepayment of any of the Mortgage Loans; and (ix) without duplication, all payments of claims under the PMI Policy. The foregoing requirements for deposit in the Collection Account shall be exclusive, it being understood and agreed that, without limiting the generality of the foregoing, payments in -66- the nature of Servicing Fees, late payment charges, assumption fees, insufficient funds charges and ancillary income (other than Prepayment Charges) need not be deposited by the Master Servicer in the Collection Account and may be retained by the Master Servicer as additional compensation. In the event the Master Servicer shall deposit in the Collection Account any amount not required to be deposited therein, it may at any time withdraw such amount from the Collection Account, any provision herein to the contrary notwithstanding. (b) On behalf of the Trust Fund, the Trustee shall establish and maintain one or more accounts (such account or accounts, the "Distribution Account"), held in trust for the benefit of the Trustee and the Certificateholders. On behalf of the Trust Fund, the Master Servicer shall deliver to the Trustee in immediately available funds for deposit in the Distribution Account on or before 1:00 p.m. New York time (i) on the Master Servicer Remittance Date, that portion of the Available Funds (calculated without regard to the references in the definition thereof to amounts that may be withdrawn from the Distribution Account) for the related Distribution Date then on deposit in the Collection Account, the amount of all Prepayment Charges collected during the applicable Prepayment Period by the Master Servicer and Master Servicer Prepayment Charge Payment Amounts in connection with the Principal Prepayment of any of the Mortgage Loans then on deposit in the Collection Account and the amount of any funds reimbursable to an Advancing Person pursuant to Section 3.29, and (ii) on each Business Day as of the commencement of which the balance on deposit in the Collection Account exceeds $75,000 following any withdrawals pursuant to the next succeeding sentence, the amount of such excess, but only if the Collection Account constitutes an Eligible Account solely pursuant to clause (ii) of the definition of "Eligible Account." If the balance on deposit in the Collection Account exceeds $75,000 as of the commencement of business on any Business Day and the Collection Account constitutes an Eligible Account solely pursuant to clause (ii) of the definition of "Eligible Account," the Master Servicer shall, on or before 1:00 p.m. New York time on such Business Day, withdraw from the Collection Account any and all amounts payable or reimbursable to the Master Servicer, the Trustee, the Originator or any Sub- Servicer pursuant to Section 3.11 and shall pay such amounts to the Persons entitled thereto. (c) Funds in the Collection Account and the Distribution Account may be invested in Permitted Investments in accordance with the provisions set forth in Section 3.12. The Master Servicer shall give notice to the NIMS Insurer and the Trustee of the location of the Collection Account maintained by it when established and prior to any change thereof. The Trustee shall give notice to the NIMS Insurer, the Master Servicer and the Depositor of the location of the Distribution Account when established and prior to any change thereof. (d) Funds held in the Collection Account at any time may be delivered by the Master Servicer to the Trustee for deposit in an account (which may be the Distribution Account and must satisfy the standards for the Distribution Account as set forth in the definition thereof) and for all purposes of this Agreement shall be deemed to be a part of the Collection Account; provided, however, that the Trustee shall have the sole authority to withdraw any funds held pursuant to this subsection (d). In the event the Master Servicer shall deliver to the Trustee for deposit in the Distribution Account any amount not required to be deposited therein, it may at any time request that the Trustee withdraw such amount from the Distribution Account and remit to it any such amount, any provision herein to the contrary notwithstanding. In addition, the Master Servicer, with respect -67- to items (i) through (iv) below, shall deliver to the Trustee from time to time for deposit, and the Trustee, with respect to items (i) through (iv) below, shall so deposit, in the Distribution Account: (i) any Advances, as required pursuant to Section 4.03; (ii) any amounts required to be deposited pursuant to Section 3.23(d) or (f) in connection with any REO Property; (iii) any amounts to be paid in connection with a purchase of Mortgage Loans and REO Properties pursuant to Section 9.01; (iv) any Compensating Interest to be deposited pursuant to Section 3.24 in connection with any Prepayment Interest Shortfall; and (v) any amounts required to be paid to the Trustee pursuant to the Agreement, including, but not limited to Section 3.06 and Section 7.02. (e) The Master Servicer shall deposit in the Collection Account any amounts required to be deposited pursuant to Section 3.12(b) in connection with losses realized on Permitted Investments with respect to funds held in the Collection Account. SECTION 3.11. Withdrawals from the Collection Account and Distribution Account. (a) The Master Servicer shall, from time to time, make withdrawals from the Collection Account for any of the following purposes or as described in Section 4.03: (i) to remit to the Trustee for deposit in the Distribution Account the amounts required to be so remitted pursuant to Section 3.10(b) or permitted to be so remitted pursuant to the first sentence of Section 3.10(d); (ii) subject to Section 3.16(d), to reimburse the Master Servicer for (a) any unreimbursed Advances to the extent of amounts received which represent Late Collections (net of the related Servicing Fees) of Monthly Payments, Liquidation Proceeds and Insurance Proceeds on Mortgage Loans with respect to which such Advances were made in accordance with the provisions of Section 4.03; or (b) any unreimbursed Advances with respect to the final liquidation of a Mortgage Loan that are Nonrecoverable Advances, but only to the extent that Late Collections, Liquidation Proceeds and Insurance Proceeds received with respect to such Mortgage Loan are insufficient to reimburse the Master Servicer for such unreimbursed Advances; (iii) subject to Section 3.16(d), to pay the Master Servicer or any Sub-Servicer (a) any unpaid Servicing Fees, (b) any unreimbursed Servicing Advances with respect to each Mortgage Loan, but only to the extent of any Late Collections, Liquidation Proceeds, Insurance Proceeds and condemnation proceeds received with respect to such Mortgage Loan, and (c) any Servicing Advances with respect to the final liquidation of a Mortgage -68- Loan that are Nonrecoverable Advances, but only to the extent that Late Collections, Liquidation Proceeds and Insurance Proceeds received with respect to such Mortgage Loan are insufficient to reimburse the Master Servicer or any Sub-Servicer for Servicing Advances; (iv) to pay to the Master Servicer as servicing compensation (in addition to the Servicing Fee) on the Master Servicer Remittance Date any interest or investment income earned on funds deposited in the Collection Account; (v) to pay to the Originator, with respect to each Mortgage Loan that has previously been purchased or replaced pursuant to Section 2.03 or Section 3.16(c) all amounts received thereon subsequent to the date of purchase or substitution, as the case may be; (vi) to reimburse the Master Servicer for any Advance or Servicing Advance previously made which the Master Servicer has determined to be a Nonrecoverable Advance in accordance with the provisions of Section 4.03; (vii) to pay, or to reimburse the Master Servicer for Servicing Advances in respect of, expenses incurred in connection with any Mortgage Loan pursuant to Section 3.16(b); (viii) to reimburse the Master Servicer for expenses incurred by or reimbursable to the Master Servicer pursuant to Section 6.03; (ix) to reimburse the NIMS Insurer, the Master Servicer (if the Master Servicer is not an Affiliate of the Originator) or the Trustee, as the case may be, for enforcement expenses reasonably incurred in respect of the breach or defect giving rise to the purchase obligation under Section 2.03 of this Agreement that were included in the Purchase Price of the Mortgage Loan, including any expenses arising out of the enforcement of the purchase obligation; (x) to pay itself any Prepayment Interest Excess; and (xi) to clear and terminate the Collection Account pursuant to Section 9.01. The foregoing requirements for withdrawal from the Collection Account shall be exclusive. In the event the Master Servicer shall deposit in the Collection Account any amount not required to be deposited therein, it may at any time withdraw such amount from the Collection Account, any provision herein to the contrary notwithstanding. The Master Servicer shall keep and maintain separate accounting, on a Mortgage Loan by Mortgage Loan basis, for the purpose of justifying any withdrawal from the Collection Account, to the extent held by or on behalf of it, pursuant to subclauses (ii), (iii), (iv), (v), (vi), (vii) and (viii) above. The Master Servicer shall provide written notification to the NIMS Insurer and the Trustee, on or prior to the next succeeding Master Servicer Remittance Date, upon making any withdrawals from the Collection Account pursuant to subclause (vi) above; provided that an -69- Officers' Certificate in the form described under Section 4.03(d) shall suffice for such written notification to the Trustee in respect hereof. (b) The Trustee shall, from time to time, make withdrawals from the Distribution Account, for any of the following purposes, without priority: (i) to make distributions in accordance with Section 4.01; (ii) to pay itself the Trustee Fee and any Extraordinary Trust Fund Expenses pursuant to Section 8.05; (iii) to pay any amounts in respect of taxes pursuant to Section 10.01(g); (iv) to clear and terminate the Distribution Account pursuant to Section 9.01; (v) to pay any amounts required to be paid to the Trustee pursuant to this Agreement, including but not limited to funds required to be paid pursuant to Section 3.06 and Section 7.02; (vi) to pay to the Trustee, any interest or investment income earned on funds deposited in the Distribution Account; (vii) to pay to an Advancing Person reimbursements for Advances and/or Servicing Advances pursuant to Section 3.29; and (viii) to pay the PMI Insurer the PMI Insurer Fee. SECTION 3.12. Investment of Funds in the Collection Account and the Distribution Account. (a) The Master Servicer may direct any depository institution maintaining the Collection Account and any REO Account to invest the funds on deposit in such accounts, and the Trustee may invest the funds on deposit in the Distribution Account (each such account, for the purposes of this Section 3.12 an "Investment Account"). All investments pursuant to this Section 3.12 shall be in one or more Permitted Investments bearing interest or sold at a discount, and maturing, unless payable on demand, (i) no later than the Business Day immediately preceding the date on which such funds are required to be withdrawn from such account pursuant to this Agreement, if a Person other than the Trustee is the obligor thereon or if such investment is managed or advised by a Person other than the Trustee or an Affiliate of the Trustee, and (ii) no later than the date on which such funds are required to be withdrawn from such account pursuant to this Agreement, if the Trustee is the obligor thereon or if such investment is managed or advised by the Trustee or any Affiliate. All such Permitted Investments shall be held to maturity, unless payable on demand. Any investment of funds in an Investment Account shall be made in the name of the Trustee (in its capacity as such), or in the name of a nominee of the Trustee. The Trustee shall be entitled to sole possession (except with respect to investment direction of funds held in the Collection Account or any REO Account and any income and gain realized thereon) over each such -70- investment, and any certificate or other instrument evidencing any such investment shall be delivered directly to the Trustee or its agent, together with any document of transfer necessary to transfer title to such investment to the Trustee or its nominee. In the event amounts on deposit in an Investment Account are at any time invested in a Permitted Investment payable on demand, the Trustee shall: (x) consistent with any notice required to be given thereunder, demand that payment thereon be made on the last day such Permitted Investment may otherwise mature hereunder in an amount equal to the lesser of (1) all amounts then payable thereunder and (2) the amount required to be withdrawn on such date; and (y) demand payment of all amounts due thereunder promptly upon determination by a Responsible Officer of the Trustee that such Permitted Investment would not constitute a Permitted Investment in respect of funds thereafter on deposit in the Investment Account. (b) All income and gain realized from the investment of funds deposited in the Collection Account and any REO Account held by or on behalf of the Master Servicer shall be for the benefit of the Master Servicer and shall be subject to its withdrawal in accordance with Section 3.11 or Section 3.23, as applicable. The Master Servicer shall deposit in the Collection Account or any REO Account, as applicable, the amount of any loss of principal incurred in respect of any such Permitted Investment made with funds in such account immediately upon realization of such loss. (c) All income and gain realized from the investment of funds deposited in the Distribution Account shall be for the benefit of the Trustee. The Trustee shall deposit in the Distribution Account the amount of any loss of principal incurred in respect of any such Permitted Investment made with funds in such accounts immediately upon realization of such loss. (d) Except as otherwise expressly provided in this Agreement, if any default occurs in the making of a payment due under any Permitted Investment, or if a default occurs in any other performance required under any Permitted Investment, the Trustee may and, subject to Section 8.01 and Section 8.02(a)(v), upon the request of the NIMS Insurer or the Holders of Certificates representing more than 50% of the Voting Rights allocated to any Class of Certificates, shall take such action as may be appropriate to enforce such payment or performance, including the institution and prosecution of appropriate proceedings. SECTION 3.13. [Reserved]. SECTION 3.14. Maintenance of Hazard Insurance and Errors and Omissions and Fidelity Coverage. (a) The Master Servicer shall cause to be maintained for each Mortgage Loan hazard insurance with extended coverage on the Mortgaged Property in an amount which is at least equal to the lesser of (i) the current Principal Balance of such Mortgage Loan and (ii) the amount necessary to fully compensate for any damage or loss to the improvements that are a part of such property on a replacement cost basis, in each case in an amount not less than such amount as is necessary to avoid the application of any coinsurance clause contained in the related hazard insurance policy. The Master Servicer shall also cause to be maintained hazard insurance with -71- extended coverage on each REO Property in an amount which is at least equal to the lesser of (i) the maximum insurable value of the improvements which are a part of such property and (ii) the outstanding Principal Balance of the related Mortgage Loan at the time it became an REO Property. The Master Servicer will comply in the performance of this Agreement with all reasonable rules and requirements of each insurer under any such hazard policies. Any amounts to be collected by the Master Servicer under any such policies (other than amounts to be applied to the restoration or repair of the property subject to the related Mortgage or amounts to be released to the Mortgagor in accordance with the procedures that the Master Servicer would follow in servicing loans held for its own account, subject to the terms and conditions of the related Mortgage and Mortgage Note) shall be deposited in the Collection Account, subject to withdrawal pursuant to Section 3.11, if received in respect of a Mortgage Loan, or in the REO Account, subject to withdrawal pursuant to Section 3.23, if received in respect of an REO Property. Any cost incurred by the Master Servicer in maintaining any such insurance shall not, for the purpose of calculating distributions to Certificateholders, be added to the unpaid Principal Balance of the related Mortgage Loan, notwithstanding that the terms of such Mortgage Loan so permit. It is understood and agreed that no earthquake or other additional insurance is to be required of any Mortgagor other than pursuant to such applicable laws and regulations as shall at any time be in force and as shall require such additional insurance. If the Mortgaged Property or REO Property is at any time in an area identified in the Federal Register by the Federal Emergency Management Agency as having special flood hazards and flood insurance has been made available, the Master Servicer will cause to be maintained a flood insurance policy in respect thereof. Such flood insurance shall be in an amount equal to the lesser of (i) the unpaid Principal Balance of the related Mortgage Loan and (ii) the maximum amount of such insurance available for the related Mortgaged Property under the national flood insurance program (assuming that the area in which such Mortgaged Property is located is participating in such program). In the event that the Master Servicer shall obtain and maintain a blanket policy with an insurer having a General Policy Rating of B:III or better in Best's Key Rating Guide (or such other rating that is comparable to such rating) insuring against hazard losses on all of the Mortgage Loans, it shall conclusively be deemed to have satisfied its obligations as set forth in the first two sentences of this Section 3.14, it being understood and agreed that such policy may contain a deductible clause, in which case the Master Servicer shall, in the event that there shall not have been maintained on the related Mortgaged Property or REO Property a policy complying with the first two sentences of this Section 3.14, and there shall have been one or more losses which would have been covered by such policy, deposit to the Collection Account from its own funds the amount not otherwise payable under the blanket policy because of such deductible clause. In connection with its activities as administrator and servicer of the Mortgage Loans, the Master Servicer agrees to prepare and present, on behalf of itself, the Trustee and Certificateholders, claims under any such blanket policy in a timely fashion in accordance with the terms of such policy. (b) The Master Servicer shall keep in force during the term of this Agreement a policy or policies of insurance covering errors and omissions for failure in the performance of the Master Servicer's obligations under this Agreement, which policy or policies shall be in such form and amount that would meet the requirements of Fannie Mae or Freddie Mac if it were the purchaser of the Mortgage Loans, unless the Master Servicer has obtained a waiver of such requirements from Fannie Mae or Freddie Mac. The Master Servicer shall provide the Trustee and the NIMS Insurer, -72- upon request, with copies of such insurance policies and fidelity bond. The Master Servicer shall also maintain a fidelity bond in the form and amount that would meet the requirements of Fannie Mae or Freddie Mac, unless the Master Servicer has obtained a waiver of such requirements from Fannie Mae or Freddie Mac. The Master Servicer shall be deemed to have complied with this provision if an Affiliate of the Master Servicer has such errors and omissions and fidelity bond coverage and, by the terms of such insurance policy or fidelity bond, the coverage afforded thereunder extends to the Master Servicer. Any such errors and omissions policy and fidelity bond shall by its terms not be cancelable without thirty days' prior written notice to the Trustee and the NIMS Insurer. The Master Servicer shall also cause each Sub-Servicer to maintain a policy of insurance covering errors and omissions and a fidelity bond which would meet such requirements. SECTION 3.15. Enforcement of Due-On-Sale Clauses; Assumption Agreements. The Master Servicer will, to the extent it has knowledge of any conveyance or prospective conveyance of any Mortgaged Property by any Mortgagor (whether by absolute conveyance or by contract of sale, and whether or not the Mortgagor remains or is to remain liable under the Mortgage Note and/or the Mortgage), exercise its rights to accelerate the maturity of such Mortgage Loan under the "due-on-sale" clause, if any, applicable thereto; provided, however, that the Master Servicer shall not be required to take such action if in its sole business judgment the Master Servicer believes it is not in the best interests of the Trust Fund and shall not exercise any such rights if prohibited by law from doing so. If the Master Servicer reasonably believes it is unable under applicable law to enforce such "due-on-sale" clause, or if any of the other conditions set forth in the proviso to the preceding sentence apply, the Master Servicer will enter into an assumption and modification agreement from or with the person to whom such property has been conveyed or is proposed to be conveyed, pursuant to which such person becomes liable under the Mortgage Note and, to the extent permitted by applicable state law, the Mortgagor remains liable thereon. The Master Servicer is also authorized to enter into a substitution of liability agreement with such person, pursuant to which the original Mortgagor is released from liability and such person is substituted as the Mortgagor and becomes liable under the Mortgage Note, provided that no such substitution shall be effective unless such person satisfies the underwriting criteria of the Master Servicer and has a credit risk rating at least equal to that of the original Mortgagor. In connection with any assumption or substitution, the Master Servicer shall apply such underwriting standards and follow such practices and procedures as shall be normal and usual in its general mortgage servicing activities and as it applies to other mortgage loans owned solely by it. The Master Servicer shall not take or enter into any assumption and modification agreement, however, unless (to the extent practicable in the circumstances) it shall have received confirmation, in writing, of the continued effectiveness of any applicable hazard insurance policy. Any fee collected by the Master Servicer in respect of an assumption, modification or substitution of liability agreement shall be retained by the Master Servicer as additional servicing compensation. In connection with any such assumption, no material term of the Mortgage Note (including but not limited to the related Mortgage Rate and the amount of the Monthly Payment) may be amended or modified, except as otherwise required pursuant to the terms thereof. The Master Servicer shall notify the Trustee that any such substitution, modification or assumption agreement has been completed by forwarding to the Trustee the executed original of such substitution, modification or assumption agreement, which document -73- shall be added to the related Mortgage File and shall, for all purposes, be considered a part of such Mortgage File to the same extent as all other documents and instruments constituting a part thereof. Notwithstanding the foregoing paragraph or any other provision of this Agreement, the Master Servicer shall not be deemed to be in default, breach or any other violation of its obligations hereunder by reason of any assumption of a Mortgage Loan by operation of law or by the terms of the Mortgage Note or any assumption which the Master Servicer may be restricted by law from preventing, for any reason whatever. For purposes of this Section 3.15, the term "assumption" is deemed to also include a sale (of the Mortgaged Property) subject to the Mortgage that is not accompanied by an assumption or substitution of liability agreement. SECTION 3.16. Realization Upon Defaulted Mortgage Loans. (a) The Master Servicer shall use its best efforts, in as practical a time frame as possible and consistent with Servicing Standard, to foreclose upon or otherwise comparably convert the ownership of properties securing such of the Mortgage Loans (including, if such is the action to be taken that results from adherence to the Loss Mitigation Procedures, selling any such Mortgage Loans other than converting the ownership of the related properties as provided in Section 3.16(e) below) as come into and continue in default and as to which no satisfactory arrangements can be made for collection of delinquent payments pursuant to Section 3.07. The Master Servicer shall be responsible for all costs and expenses incurred by it in any such proceedings; provided, however, that such costs and expenses will be recoverable as Servicing Advances by the Master Servicer as contemplated in Section 3.11 and Section 3.23. The foregoing is subject to the provision that, in any case in which a Mortgaged Property shall have suffered damage from an Uninsured Cause, the Master Servicer shall not be required to expend its own funds toward the restoration of such property unless it shall determine in its discretion that such restoration will increase the proceeds of liquidation of the related Mortgage Loan after reimbursement to itself for such expenses. (b) Notwithstanding the foregoing provisions of this Section 3.16 or any other provision of this Agreement, with respect to any Mortgage Loan as to which the Master Servicer has received actual notice of, or has actual knowledge of, the presence of any toxic or hazardous substance on the related Mortgaged Property, the Master Servicer shall not, on behalf of the Trustee, either (i) obtain title to such Mortgaged Property as a result of or in lieu of foreclosure or otherwise, or (ii) otherwise acquire possession of, or take any other action with respect to, such Mortgaged Property, if, as a result of any such action, the Trustee, the Trust Fund or the Certificateholders would be considered to hold title to, to be a "mortgagee-in-possession" of, or to be an "owner" or "operator" of such Mortgaged Property within the meaning of the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended from time to time, or any comparable law, unless the Master Servicer has also previously determined, based on its reasonable judgment and a report prepared by a Person who regularly conducts environmental audits using customary industry standards, that: (1) such Mortgaged Property is in compliance with applicable environmental laws or, if not, that it would be in the best economic interest of the Trust Fund to take such actions as are necessary to bring the Mortgaged Property into compliance therewith; and -74- (2) there are no circumstances present at such Mortgaged Property relating to the use, management or disposal of any hazardous substances, hazardous materials, hazardous wastes, or petroleum-based materials for which investigation, testing, monitoring, containment, clean-up or remediation could be required under any federal, state or local law or regulation, or that if any such materials are present for which such action could be required, that it would be in the best economic interest of the Trust Fund to take such actions with respect to the affected Mortgaged Property. Notwithstanding the foregoing, if such environmental audit reveals, or if the Master Servicer has actual knowledge or notice, that such Mortgaged Property contains such wastes or substances, the Master Servicer shall not foreclose or accept a deed in lieu of foreclosure without the prior written consent of the NIMS Insurer. The cost of the environmental audit report contemplated by this Section 3.16 shall be advanced by the Master Servicer, subject to the Master Servicer's right to be reimbursed therefor from the Collection Account as provided in Section 3.11(a)(vii), such right of reimbursement being prior to the rights of Certificateholders to receive any amount in the Collection Account received in respect of the affected Mortgage Loan or other Mortgage Loans. If the Master Servicer determines, as described above, that it is in the best economic interest of the Trust Fund to take such actions as are necessary to bring any such Mortgaged Property into compliance with applicable environmental laws, or to take such action with respect to the containment, clean-up or remediation of hazardous substances, hazardous materials, hazardous wastes or petroleum-based materials affecting any such Mortgaged Property, then the Master Servicer shall take such action as it deems to be in the best economic interest of the Trust Fund; provided that any amounts disbursed by the Master Servicer pursuant to this Section 3.16(b) shall constitute Servicing Advances, subject to Section 4.03(d). The cost of any such compliance, containment, cleanup or remediation shall be advanced by the Master Servicer, subject to the Master Servicer's right to be reimbursed therefor from the Collection Account as provided in Section 3.11(a)(iii) and (a)(vii), such right of reimbursement being prior to the rights of Certificateholders to receive any amount in the Collection Account received in respect of the affected Mortgage Loan or other Mortgage Loans. (c)(i) The NIMS Insurer may, at its option, purchase a Mortgage Loan which has become 90 or more days delinquent or for which the Master Servicer has accepted a deed in lieu of foreclosure. Prior to purchase pursuant to this Section 3.16(c)(i), the Master Servicer shall be required to continue to make Advances pursuant to Section 4.03. The NIMS Insurer shall not use any procedure in selecting Mortgage Loans to be repurchased which is materially adverse to the interests of the Certificateholders. The NIMS Insurer shall purchase such delinquent Mortgage Loan at a price equal to the Purchase Price of such Mortgage Loan. Any such purchase of a Mortgage Loan pursuant to this Section 3.16(c)(i) shall be accomplished by remittance to the Master Servicer for deposit in the Collection Account of the amount of the Purchase Price. The Trustee shall immediately effectuate the conveyance of such delinquent Mortgage Loan to the NIMS Insurer to the extent necessary to vest in the NIMS Insurer title to such Mortgage Loan, including the prompt delivery of all documentation to the NIMS Insurer. -75- (ii) If the Master Servicer Optional Purchase Delinquency Trigger has been met, the Master Servicer may, at its option, purchase a Mortgage Loan which has become 90 or more days delinquent or for which the Master Servicer has accepted a deed in lieu of foreclosure. Prior to purchase pursuant to this Section 3.16(c)(ii), the Master Servicer shall be required to continue to make Advances pursuant to Section 4.03. The Master Servicer shall purchase such delinquent Mortgage Loan at a price equal to the Purchase Price of such Mortgage Loan. Any such purchase of a Mortgage Loan pursuant to this Section 3.16(c)(ii) shall be accomplished by deposit in the Collection Account of the amount of the Purchase Price. The Trustee shall immediately effectuate the conveyance of such delinquent Mortgage Loan to the Master Servicer to the extent necessary, including the prompt delivery of all documentation to the Master Servicer. Notwithstanding the foregoing: (A) the Master Servicer shall have the option to purchase pursuant to this Section 3.16(c)(ii) only such delinquent Mortgage Loans having an aggregate Principal Balance such that, if such delinquent Mortgage Loans were not in the Trust, the Master Servicer Optional Purchase Delinquency Trigger would not be met; (B) if the Master Servicer purchases any delinquent Mortgage Loans pursuant to this Section 3.16(c)(ii), it must purchase Mortgage Loans that are delinquent the greatest number of days before it may purchase any that are delinquent any fewer number of days; (C) if the Master Servicer purchases some but not all Mortgage Loans that are delinquent any given number of days, it must purchase Mortgage Loans having the same delinquency status in the order of lowest Principal Balance to highest Principal Balance; (D) the Master Servicer may at any time relinquish its rights to purchase delinquent Mortgage Loans pursuant to this Section 3.16(c)(ii) in writing delivered to the Trustee, and from and after the taking of such action by the Master Servicer, the provisions of this Section 3.16(c)(ii) shall no longer be of any force or effect. (d) Proceeds received in connection with any Final Recovery Determination, as well as any recovery resulting from a partial collection of Insurance Proceeds, Liquidation Proceeds or condemnation proceeds, in respect of any Mortgage Loan, will be applied in the following order of priority: first, to unpaid Servicing Fees; second, to reimburse the Master Servicer or any Sub- Servicer for any related unreimbursed Servicing Advances pursuant to Section 3.11(a)(iii) and Advances pursuant to Section 3.11(a)(ii); third, to accrued and unpaid interest on the Mortgage Loan, to the date of the Final Recovery Determination, or to the Due Date prior to the Distribution Date on which such amounts are to be distributed if not in connection with a Final Recovery Determination; and fourth, as a recovery of principal of the Mortgage Loan. The portion of the recovery so allocated to unpaid Servicing Fees shall be reimbursed to the Master Servicer or any Sub-Servicer pursuant to Section 3.11(a)(iii). SECTION 3.17. Trustee to Cooperate; Release of Mortgage Files. (a) Upon the payment in full of any Mortgage Loan, or the receipt by the Master Servicer of a notification that payment in full shall be escrowed in a manner customary for such purposes, the Master Servicer shall deliver to the Trustee, in written (with two executed copies) or electronic format, a Request for Release in the form of Exhibit E (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 3.10 have been or will be so deposited) signed by a Servicing Officer (or in a mutually agreeable electronic format that -76- will, in lieu of a signature on its face, originate from a Servicing Officer) and shall request delivery to it of the Mortgage File. Upon receipt of such certification and request, the Trustee shall, within three Business Days, release and send by overnight mail, at the expense of the Master Servicer, the related Mortgage File to the Master Servicer. The Trustee agrees to indemnify the Master Servicer, out of its own funds, for any loss, liability or expense (other than special, indirect, punitive or consequential damages which will not be paid by the Trustee) incurred by the Master Servicer as a proximate result of the Trustee's breach of its obligations pursuant to this Section 3.17. No expenses incurred in connection with any instrument of satisfaction or deed of reconveyance shall be chargeable to the Collection Account or the Distribution Account. (b) From time to time and as appropriate for the servicing or foreclosure of any Mortgage Loan, including, for this purpose, collection under any insurance policy relating to the Mortgage Loans, the Trustee shall, upon any request made by or on behalf of the Master Servicer and delivery to the Trustee, in written (with two executed copies) or electronic format, of a Request for Release in the form of Exhibit E signed by a Servicing Officer (or in a mutually agreeable electronic format that will, in lieu of a signature on its face, originate from a Servicing Officer), release the related Mortgage File to the Master Servicer within three Business Days, and the Trustee shall, at the direction of the Master Servicer, execute such documents as shall be necessary to the prosecution of any such proceedings. Such Request for Release shall obligate the Master Servicer to return each and every document previously requested from the Mortgage File to the Trustee when the need therefor by the Master Servicer no longer exists, unless the Mortgage Loan has been liquidated and the Liquidation Proceeds relating to the Mortgage Loan have been deposited in the Collection Account or the Mortgage File or such document 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 either judicially or non- judicially, and the Master Servicer has delivered, or caused to be delivered, to the Trustee an additional Request for Release certifying as to such liquidation or action or proceedings. Upon the request of the Trustee, the Master Servicer shall provide notice to the Trustee of the name and address of the Person to which such Mortgage File or such document was delivered and the purpose or purposes of such delivery. Upon receipt of a Request for Release, in written (with two executed copies) or electronic format, from a Servicing Officer stating that such Mortgage Loan was liquidated and that all amounts received or to be received in connection with such liquidation that are required to be deposited into the Collection Account have been so deposited, or that such Mortgage Loan has become an REO Property, such Mortgage Loan shall be released by the Trustee to the Master Servicer or its designee. (c) Upon written certification of a Servicing Officer, the Trustee shall execute and deliver to the Master Servicer or the Sub-Servicer, as the case may be, copies of, any court pleadings, requests for trustee's sale or other documents necessary to the foreclosure or trustee's sale in respect of a Mortgaged Property or to any legal action brought to obtain judgment against any Mortgagor on the Mortgage Note or Mortgage or to obtain a deficiency judgment, or to enforce any other remedies or rights provided by the Mortgage Note or Mortgage or otherwise available at law or in equity. Each such certification shall include a request that such pleadings or documents be executed by the Trustee and a statement as to the reason such documents or pleadings are required and that the execution and delivery thereof by the Trustee will not invalidate or otherwise affect the lien of -77- the Mortgage, except for the termination of such a lien upon completion of the foreclosure or trustee's sale. SECTION 3.18. Servicing Compensation. As compensation for the activities of the Master Servicer hereunder, the Master Servicer shall be entitled to the Servicing Fee with respect to each Mortgage Loan payable solely from payments of interest in respect of such Mortgage Loan, subject to Section 3.24. In addition, the Master Servicer shall be entitled to recover unpaid Servicing Fees out of Insurance Proceeds, Liquidation Proceeds or condemnation proceeds to the extent permitted by Section 3.11(a)(iii) and out of amounts derived from the operation and sale of an REO Property to the extent permitted by Section 3.23. Except as provided in Section 3.29, the right to receive the Servicing Fee may not be transferred in whole or in part except in connection with the transfer of all of the Master Servicer's responsibilities and obligations under this Agreement; provided, however, that the Master Servicer may pay from the Servicing Fee any amounts due to a Sub-Servicer pursuant to a Sub-Servicing Agreement entered into under Section 3.02. Additional servicing compensation in the form of assumption fees, late payment charges, insufficient funds charges, ancillary income or otherwise (other than Prepayment Charges) shall be retained by the Master Servicer only to the extent such fees or charges are received by the Master Servicer. The Master Servicer shall also be entitled pursuant to Section 3.11(a)(iv) to withdraw from the Collection Account and pursuant to Section 3.23(b) to withdraw from any REO Account, as additional servicing compensation, interest or other income earned on deposits therein, subject to Section 3.12 and Section 3.24. The Master Servicer shall be required to pay all expenses incurred by it in connection with its servicing activities hereunder (including premiums for the insurance required by Section 3.14, to the extent such premiums are not paid by the related Mortgagors or by a Sub-Servicer and servicing compensation of each Sub-Servicer) and shall not be entitled to reimbursement therefor except as specifically provided herein. The Master Servicer shall be entitled to any Prepayment Interest Excess, which it may withdraw from the Collection Account pursuant to Section 3.11(a)(ix). SECTION 3.19. Reports to the Trustee; Collection Account Statements. Not later than twenty days after each Distribution Date, the Master Servicer shall forward to the Trustee, the NIMS Insurer and the Depositor the most current available bank statement for the Collection Account. Copies of such statement shall be provided by the Trustee to any Certificateholder and to any Person identified to the Trustee as a prospective transferee of a Certificate, upon request at the expense of the requesting party, provided such statement is delivered by the Master Servicer to the Trustee. SECTION 3.20. Statement as to Compliance. The Master Servicer will deliver to the Trustee, the NIMS Insurer and the Depositor not later than February 28th of each calendar year, commencing in 2003, an Officers' Certificate stating, as to each signatory thereof, that (i) a review of the activities of the Master Servicer during -78- the preceding year and of performance under this Agreement has been made under such officers' supervision and (ii) to the best of such officers' knowledge, based on such review, the Master Servicer has fulfilled all of its obligations under this Agreement throughout such year, or, if there has been a default in the fulfillment of any such obligation, specifying each such default known to such officer and the nature and status thereof. Copies of any such statement shall be provided by the Trustee to any Certificateholder and to any Person identified to the Trustee as a prospective transferee of a Certificate, upon request at the expense of the requesting party, provided such statement is delivered by the Master Servicer to the Trustee. SECTION 3.21. Independent Public Accountants' Servicing Report. Not later than February 28th of each calendar year, commencing in 2003, the Master Servicer, at its expense, shall cause a nationally recognized firm of independent certified public accountants to furnish to the Master Servicer a report stating that (i) it has obtained a letter of representation regarding certain matters from the management of the Master Servicer which includes an assertion that the Master Servicer has complied with certain minimum residential mortgage loan servicing standards, identified in the Uniform Single Attestation Program for Mortgage Bankers established by the Mortgage Bankers Association of America, with respect to the servicing of residential mortgage loans during the most recently completed fiscal year and (ii) on the basis of an examination conducted by such firm in accordance with standards established by the American Institute of Certified Public Accountants, such representation is fairly stated in all material respects, subject to such exceptions and other qualifications that may be appropriate. In rendering its report such firm may rely, as to matters relating to the direct servicing of residential mortgage loans by Sub-Servicers, upon comparable reports of firms of independent certified public accountants rendered on the basis of examinations conducted in accordance with the same standards (rendered within one year of such report) with respect to those Sub-Servicers. Immediately upon receipt of such report, the Master Servicer shall furnish a copy of such report to the Trustee, the NIMS Insurer and each Rating Agency. Copies of such statement shall be provided by the Trustee to any Certificateholder upon request at the Master Servicer's expense, provided that such statement is delivered by the Master Servicer to the Trustee. SECTION 3.22. Access to Certain Documentation. The Master Servicer shall provide to the Office of Thrift Supervision, the FDIC, and any other federal or state banking or insurance regulatory authority that may exercise authority over any Certificateholder, access to the documentation regarding the Mortgage Loans required by applicable laws and regulations. Such access shall be afforded without charge, but only upon reasonable request and during normal business hours at the offices of the Master Servicer designated by it. In addition, access to the documentation regarding the Mortgage Loans will be provided to any Certificateholder, the Trustee, the NIMS Insurer and to any Person identified to the Master Servicer as a prospective transferee of a Certificate, upon reasonable request during normal business hours at the offices of the Master Servicer designated by it at the expense of the Person requesting such access. -79- SECTION 3.23. Title, Management and Disposition of REO Property. (a) The deed or certificate of sale of any REO Property shall be taken in the name of the Trustee, or its nominee, in trust for the benefit of the Certificateholders. The Master Servicer, on behalf of REMIC I, shall sell any REO Property as soon as practical and in any event no later than the end of the third full taxable year after the taxable year in which such REMIC acquires ownership of such REO Property for purposes of Section 860G(a)(8) of the Code or request from the Internal Revenue Service, no later than 60 days before the day on which the three-year grace period would otherwise expire, an extension of such three-year period, unless the Master Servicer shall have delivered to the Trustee and the NIMS Insurer an Opinion of Counsel acceptable to the NIMS Insurer and addressed to the Trustee, the NIMS Insurer and the Depositor, to the effect that the holding by the REMIC of such REO Property subsequent to three years after its acquisition will not result in the imposition on the REMIC of taxes on "prohibited transactions" thereof, as defined in Section 860F of the Code, or cause any of the REMICs created hereunder to fail to qualify as a REMIC under Federal law at any time that any Certificates are outstanding. The Master Servicer shall manage, conserve, protect and operate each REO Property for the Certificateholders solely for the purpose of its prompt disposition and sale in a manner which does not cause such REO Property to fail to qualify as "foreclosure property" within the meaning of Section 860G(a)(8) of the Code or result in the receipt by any of the REMICs created hereunder of any "income from non-permitted assets" within the meaning of Section 860F(a)(2)(B) of the Code, or any "net income from foreclosure property" which is subject to taxation under the REMIC Provisions. (b) The Master Servicer shall separately account for all funds collected and received in connection with the operation of any REO Property and shall establish and maintain, or cause to be established and maintained, with respect to REO Properties an account held in trust for the Trustee for the benefit of the Certificateholders (the "REO Account"), which shall be an Eligible Account. The Master Servicer shall be permitted to allow the Collection Account to serve as the REO Account, subject to separate ledgers for each REO Property. The Master Servicer shall be entitled to retain or withdraw any interest income paid on funds deposited in the REO Account. (c) The Master Servicer shall have full power and authority, subject only to the specific requirements and prohibitions of this Agreement, to do any and all things in connection with any REO Property as are consistent with the manner in which the Master Servicer manages and operates similar property owned by the Master Servicer or any of its Affiliates, all on such terms and for such period (subject to the requirement of prompt disposition set forth in Section 3.23(a)) as the Master Servicer deems to be in the best interests of Certificateholders. In connection therewith, the Master Servicer shall deposit, or cause to be deposited in the clearing account in which it customarily deposits payments and collections on mortgage loans in connection with its mortgage loan servicing activities on a daily basis, and in no event more than one Business Day after the Master Servicer's receipt thereof, and shall thereafter deposit in the REO Account, in no event more than two Business Days after the Master Servicer's receipt thereof, all revenues received by it with respect to an REO Property and shall withdraw therefrom funds necessary for the proper operation, management and maintenance of such REO Property including, without limitation: (i) all insurance premiums due and payable in respect of such REO Property; -80- (ii) all real estate taxes and assessments in respect of such REO Property that may result in the imposition of a lien thereon; and (iii) all costs and expenses necessary to maintain such REO Property. To the extent that amounts on deposit in the REO Account with respect to an REO Property are insufficient for the purposes set forth in clauses (i) through (iii) above with respect to such REO Property, the Master Servicer shall advance from its own funds such amount as is necessary for such purposes if, but only if, the Master Servicer would make such advances if the Master Servicer owned the REO Property and if in the Master Servicer's judgment, the payment of such amounts will be recoverable from the rental or sale of the REO Property. Notwithstanding the foregoing, neither the Master Servicer nor the Trustee shall: (A) authorize the Trust Fund to enter into, renew or extend any New Lease with respect to any REO Property, if the New Lease by its terms will give rise to any income that does not constitute Rents from Real Property; (B) authorize any amount to be received or accrued under any New Lease other than amounts that will constitute Rents from Real Property; (C) authorize any construction on any REO Property, other than the completion of a building or other improvement thereon, and then only if more than ten percent of the construction of such building or other improvement was completed before default on the related Mortgage Loan became imminent, all within the meaning of Section 856(e)(4)(B) of the Code; or (D) authorize any Person to Directly Operate any REO Property on any date more than 90 days after its date of acquisition by the Trust Fund; unless, in any such case, the Master Servicer has obtained an Opinion of Counsel, provided to the Trustee and the NIMS Insurer, to the effect that such action will not cause such REO Property to fail to qualify as "foreclosure property" within the meaning of Section 860G(a)(8) of the Code at any time that it is held by the REMIC, in which case the Master Servicer may take such actions as are specified in such Opinion of Counsel. The Master Servicer may contract with any Independent Contractor for the operation and management of any REO Property, provided that: (1) the terms and conditions of any such contract shall not be inconsistent herewith; (2) any such contract shall require, or shall be administered to require, that the Independent Contractor pay all costs and expenses incurred in connection with the operation and management of such REO Property, including those listed above and remit all related revenues (net of such costs and expenses) to the Master Servicer as soon as practicable, but -81- in no event later than thirty days following the receipt thereof by such Independent Contractor; (3) none of the provisions of this Section 3.23(c) relating to any such contract or to actions taken through any such Independent Contractor shall be deemed to relieve the Master Servicer of any of its duties and obligations to the Trustee on behalf of the Certificateholders with respect to the operation and management of any such REO Property; and (4) the Master Servicer shall be obligated with respect thereto to the same extent as if it alone were performing all duties and obligations in connection with the operation and management of such REO Property. The Master Servicer shall be entitled to enter into any agreement with any Independent Contractor performing services for it related to its duties and obligations hereunder for indemnification of the Master Servicer by such Independent Contractor, and nothing in this Agreement shall be deemed to limit or modify such indemnification. The Master Servicer shall be solely liable for all fees owed by it to any such Independent Contractor, irrespective of whether the Master Servicer's compensation pursuant to Section 3.18 is sufficient to pay such fees; provided, however, that to the extent that any payments made by such Independent Contractor would constitute Servicing Advances if made by the Master Servicer, such amounts shall be reimbursable as Servicing Advances made by the Master Servicer. (d) In addition to the withdrawals permitted under Section 3.23(c), the Master Servicer may from time to time make withdrawals from the REO Account for any REO Property: (i) to pay itself or any Sub-Servicer unpaid Servicing Fees in respect of the related Mortgage Loan; and (ii) to reimburse itself or any Sub-Servicer for unreimbursed Servicing Advances and Advances made in respect of such REO Property or the related Mortgage Loan. On the Master Servicer Remittance Date, the Master Servicer shall withdraw from each REO Account maintained by it and deposit into the Distribution Account in accordance with Section 3.10(d)(ii), for distribution on the related Distribution Date in accordance with Section 4.01, the income from the related REO Property received during the prior calendar month, net of any withdrawals made pursuant to Section 3.23(c) or this Section 3.23(d). (e) Subject to the time constraints set forth in Section 3.23(a), each REO Disposition shall be carried out by the Master Servicer in a manner, at such price and upon such terms and conditions as shall be in conformity with the requirements of the Loss Mitigation Procedures and as shall be normal and usual in its Servicing Standard. (f) The proceeds from the REO Disposition, net of any amount required by law to be remitted to the Mortgagor under the related Mortgage Loan and net of any payment or reimbursement to the Master Servicer or any Sub-Servicer as provided above, shall be deposited in the Distribution Account in accordance with Section 3.10(d)(ii) on the Master Servicer Remittance Date in the month following the receipt thereof for distribution on the related Distribution Date in accordance with Section 4.01. Any REO Disposition shall be for cash only (unless changes in the REMIC Provisions made subsequent to the Startup Day allow a sale for other consideration). -82- (g) The Master Servicer shall file information returns with respect to the receipt of mortgage interest received in a trade or business, reports of foreclosures and abandonments of any Mortgaged Property and cancellation of indebtedness income with respect to any Mortgaged Property as required by Sections 6050H, 6050J and 6050P of the Code, respectively. Such reports shall be in form and substance sufficient to meet the reporting requirements imposed by such Sections 6050H, 6050J and 6050P of the Code. SECTION 3.24. Obligations of the Master Servicer in Respect of Prepayment Interest Shortfalls. Not later than 1:00 p.m. New York time on each Master Servicer Remittance Date, the Master Servicer shall remit to the Distribution Account an amount ("Compensating Interest") equal to the lesser of (A) the aggregate of the Prepayment Interest Shortfalls for the related Distribution Date and (B) its aggregate Servicing Fee received in the related Due Period, any interest or investment income earned on funds deposited in the Collection Account and any Prepayment Interest Excess earned during the related Prepayment Period. The Master Servicer shall not have the right to reimbursement for any amounts remitted to the Trustee in respect of Compensating Interest. Such amounts so remitted shall be included in the Available Funds and distributed therewith on the next Distribution Date. The Master Servicer shall not be obligated to pay Compensating Interest with respect to Relief Act Interest Shortfalls. SECTION 3.25. [Reserved] SECTION 3.26. Obligations of the Master Servicer in Respect of Mortgage Rates and Monthly Payments. In the event that a shortfall in any collection on or liability with respect to the Mortgage Loans in the aggregate results from or is attributable to adjustments to Mortgage Rates, Monthly Payments or Stated Principal Balances that were made by the Master Servicer in a manner not consistent with the terms of the related Mortgage Note and this Agreement, the Master Servicer, upon discovery or receipt of notice thereof, immediately shall deposit in the Collection Account from its own funds the amount of any such shortfall and shall indemnify and hold harmless the Trust Fund, the Trustee, the Depositor and any successor servicer in respect of any such liability. Such indemnities shall survive the termination or discharge of this Agreement. Notwithstanding the foregoing, this Section 3.26 shall not limit the ability of the Master Servicer to seek recovery of any such amounts from the related Mortgagor under the terms of the related Mortgage Note, as permitted by law. SECTION 3.27. Solicitations. From and after the Closing Date, the Master Servicer agrees that it will not take any action or permit or cause any action to be taken by any of its agents and Affiliates, or by any independent contractors or independent mortgage brokerage companies on the Master Servicer's behalf, to personally, by telephone, mail or electronic mail, solicit the Mortgagor under any Mortgage Loan for the purpose of refinancing such Mortgage Loan; provided, that the Master Servicer may solicit any Mortgagor for whom the Master Servicer has received a request for -83- verification of mortgage, a request for demand for payoff, a mortgagor initiated written or verbal communication indicating a desire to prepay the related Mortgage Loan, another mortgage company has pulled a credit report on the mortgagor or the mortgagor initiates a title search; provided further, it is understood and agreed that promotions undertaken by the Master Servicer or any of its Affiliates which (i) concern optional insurance products or other additional products or (ii) are directed to the general public at large, including, without limitation, mass mailings based on commercially acquired mailing lists, newspaper, radio and television advertisements shall not constitute solicitation under this Section, nor is the Master Servicer prohibited from responding to unsolicited requests or inquiries made by a Mortgagor or an agent of a Mortgagor. Furthermore, the Master Servicer shall be permitted to include in its monthly statements to borrowers or otherwise, statements regarding the availability of the Master Servicer's counseling services with respect to refinancing mortgage loans. SECTION 3.28. Net WAC Rate Carryover Reserve Account. No later than the Closing Date, the Trustee shall establish and maintain with itself a separate, segregated trust account titled, "Net WAC Rate Carryover Reserve Account, Wells Fargo Bank Minnesota, National Association, as Trustee, in trust for the registered holders of MASTR Asset Backed Securities Trust 2002-OPT1, Mortgage Pass-Through Certificates." On the Closing Date, the Depositor will deposit, or cause to be deposited, into the Net WAC Rate Carryover Reserve Account $1,000. In addition, the amount deposited in the Net WAC Rate Carryover Reserve Account shall be increased by any payments received by the Trustee under the Cap Contract and deposited into the Net WAC Rate Carryover Reserve Account for the benefit of the Class A-2 Certificates. On each Distribution Date as to which there is a Net WAC Rate Carryover Amount payable to the Class A Certificates and/or the Mezzanine Certificates, the Trustee has been directed by the Class CE Certificateholders to, and therefore will, deposit into the Net WAC Rate Carryover Reserve Account the amounts described in Section 4.01(a)(4)(xv), rather than distributing such amounts to the Class CE Certificateholders. On each such Distribution Date, the Trustee shall hold all such amounts for the benefit of the Holders of the Class A Certificates and the Mezzanine Certificates, and will distribute such amounts to the Holders of the Class A Certificates and/or the Mezzanine Certificates in the amounts and priorities set forth in Section 4.01(d). If no Net WAC Rate Carryover Amounts are payable on a Distribution Date, the Trustee shall deposit into the Net WAC Rate Carryover Reserve Account on behalf of the Class CE Certificateholders, from amounts otherwise distributable to the Class CE Certificateholders, an amount such that when added to other amounts already on deposit in the Net WAC Rate Carryover Reserve Account, the aggregate amount on deposit therein is equal to $1,000. For federal and state income tax purposes, the Class CE Certificateholders will be deemed to be the owners of the Net WAC Rate Carryover Reserve Account and all amounts deposited into the Net WAC Rate Carryover Reserve Account (other than the initial deposit therein of $1,000) shall be treated as amounts distributed by REMIC II to the Holders of the Class CE Certificates. Upon the termination of the Trust Fund, or the payment in full of the Class A Certificates and the Mezzanine Certificates, all amounts remaining on deposit in the Net WAC Rate Carryover Reserve Account will be released by the Trust Fund and distributed to the Class CE -84- Certificateholders or their designees. The Net WAC Rate Carryover Reserve Account will be part of the Trust Fund but not part of any REMIC and any payments to the Holders of the Class A Certificates or the Mezzanine Certificates of Net WAC Rate Carryover Amounts will not be payments with respect to a "regular interest" in a REMIC within the meaning of Code Section 860(G)(a)(1). By accepting a Class CE Certificate, each Class CE Certificateholder hereby agrees to direct the Trustee, and the Trustee hereby is directed, to deposit into the Net WAC Rate Carryover Reserve Account the amounts described above on each Distribution Date as to which there is any Net WAC Rate Carryover Amount rather than distributing such amounts to the Class CE Certificateholders. By accepting a Class CE Certificate, each Class CE Certificateholder further agrees that such direction is given for good and valuable consideration, the receipt and sufficiency of which is acknowledged by such acceptance. At the direction of the Holders of a majority in Percentage Interest in the Class CE Certificates, the Trustee shall direct any depository institution maintaining the Net WAC Rate Carryover Reserve Account to invest the funds in such account in one or more Permitted Investments bearing interest or sold at a discount, and maturing, unless payable on demand, (i) no later than the Business Day immediately preceding the date on which such funds are required to be withdrawn from such account pursuant to this Agreement, if a Person other than the Trustee or an Affiliate manages or advises such investment, and (ii) no later than the date on which such funds are required to be withdrawn from such account pursuant to this Agreement, if the Trustee or an Affiliate manages or advises such investment. If no investment direction of the Holders of a majority in Percentage Interest in the Class CE Certificates with respect to the Net WAC Rate Carryover Reserve Account is received by the Trustee, the Trustee shall invest the funds in such account in Permitted Investments managed by the Trustee or an Affiliate of the kind described in clause (vi) of the definition of Permitted Investments. All income and gain earned upon such investment shall be deposited into the Net WAC Rate Carryover Reserve Account. For federal tax return and information reporting, the right of the Class A Certificateholders and the Mezzanine Certificateholders to receive payments from the Net WAC Rate Carryover Reserve Account in respect of any Net Wac Rate Carryover Amount shall be assigned a value of zero. SECTION 3.29. Advance Facility. (a) The Master Servicer and/or the Trustee on behalf of the Trust Fund, in either case, with the consent of the NIMS Insurer, is hereby authorized to enter into a facility with any Person which provides that such Person (an "Advancing Person") may fund Advances and/or Servicing Advances under this Agreement, although no such facility shall reduce or otherwise affect the Master Servicer's obligation to fund such Advances and/or Servicing Advances. To the extent that an Advancing Person makes all or a portion of any Advance or any Servicing Advance and provides the Trustee with notice acknowledged by the Servicer that such Advancing Person is entitled to reimbursement, such Advancing Person shall be entitled to receive reimbursement pursuant to this Agreement for such amount to the extent provided in Section 3.29(b). Such notice from the Advancing Person must specify the amount of the reimbursement and must specify which -85- Section of this Agreement permits the applicable Advance or Servicing Advance to be reimbursed. The Trustee shall be entitled to rely without independent investigation on the Advancing Person's statement with respect to the amount of any reimbursement pursuant to this Section 3.29 and with respect to the Advancing Person's statement with respect to the Section of this Agreement that permits the applicable Advance or Servicing Advance to be reimbursed. An Advancing Person whose obligations are limited to the making of Advances and/or Servicing Advances shall not be required to meet the qualifications of a Master Servicer or a Sub-Servicer pursuant to Section 6.06 hereof and will not be deemed to be a Sub-Servicer under this Agreement. If the terms of a facility proposed to be entered into with an Advancing Person by the Trust Fund would not materially and adversely affect the interests of any Certificateholder, then the NIMS Insurer shall not withhold its consent to the Trust Fund's entering such facility. (b) If an advancing facility is entered into, then the Master Servicer shall not be permitted to reimburse itself therefor under Section 3.11(ii), Section 3.11(iii), Section 3.11(v), Section 3.11(vi) Section 3.11(vii) and Section 4.04(b) prior to the remittance to the Trust Fund, but instead the Master Servicer shall include such amounts in the applicable remittance to the Trustee made pursuant to Section 3.10(a). The Trustee is hereby authorized to pay to the Advancing Person, reimbursements for Advances and Servicing Advances from the Distribution Account to the same extent the Master Servicer would have been permitted to reimburse itself for such Advances and/or Servicing Advances in accordance with Section 3.11(ii), Section 3.11(iii), Section 3.11(v), Section 3.11(vi), Section 3.11(vii) or Section 4.04(b), as the case may be, had the Master Servicer itself funded such Advance or Servicing Advance. The Trustee is hereby authorized to pay directly to the Advancing Person such portion of the Servicing Fee as the parties to any advancing facility agree. (c) All Advances and Servicing Advances made pursuant to the terms of this Agreement shall be deemed made and shall be reimbursed on a "first in-first out" (FIFO) basis. SECTION 3.30. PMI Policy; Claims Under the PMI Policy. Notwithstanding anything to the contrary elsewhere in this Article III, the Master Servicer shall not agree to any modification or assumption of a PMI Mortgage Loan or take any other action with respect to a PMI Mortgage Loan that could result in denial of coverage under the PMI Policy. The Master Servicer shall notify the PMI Insurer that the Trustee, on behalf of the Certificateholders, is the Insured, as that term is defined in the PMI Policy, of each PMI Mortgage Loan. The Master Servicer shall, on behalf of the Trustee, prepare and file on a timely basis with the PMI Insurer, with a copy to the Trustee, all claims which may be made under the PMI Policy with respect to the PMI Mortgage Loans. Consistent with all rights and obligations hereunder, the Master Servicer shall take all actions required under the PMI Policy as a condition to the payment of any such claim. Any amount received from the PMI Insurer with respect to any such PMI Mortgage Loan shall be deposited by the Master Servicer, no later than two Business Days following receipt thereof, into the Collection Account. SECTION 3.31. Excess Net WAC Rate Reserve Account. No later than the Closing Date, the Trustee shall establish and maintain with itself a separate, segregated trust account titled, "Excess Net WAC Rate Reserve Account, Wells Fargo -86- Bank Minnesota, National Association, as Trustee, in trust for the registered holders of MASTR Asset Backed Securities Trust 2002-OPT1, Mortgage Pass-Through Certificates." On each Distribution Date as to which there is an Excess Group Net WAC Rate Amount payable on the Class A Certificates or the Class CE Certificates, the Trustee has been directed by the Class A Certificateholders to, and therefore shall, deposit into the Excess Net WAC Rate Reserve Account, the Excess Group Net WAC Rate Amount, rather than distributing such amounts to the applicable Class A Certificateholders. On each such Distribution Date, the Trustee shall hold all such amounts for the benefit of the Holders of the applicable Class A Certificates or the Class CE Certificates, and shall distribute such amounts to the Holders of the applicable Class A Certificates and/or the Class CE Certificates to the extent of the Excess Group Net WAC Rate Amount. For federal and state income tax purposes, the Class CE Certificateholders will be deemed to be the owners of the Excess Net WAC Rate Reserve Account and all amounts deposited into the Excess Net WAC Rate Reserve Account shall be treated as amounts distributed by REMIC II to the Holders of the Class CE Certificates. Upon the termination of the Trust Fund, or the payment in full of the Class A Certificates, all amounts remaining on deposit in the Excess Net WAC Rate Reserve Account shall be released by the Trust Fund and distributed to the Class CE Certificateholders or their designees. The Excess Net WAC Rate Reserve Account shall be part of the Trust Fund but not part of any Trust REMIC and any payments to the Holders of the Class A Certificates or the Class CE Certificates of Excess Group Net WAC Rate Amount will not be payments with respect to a "regular interest" in a REMIC within the meaning of Code Section 860(G)(a)(1). By accepting a Class A Certificate, such Certificateholders hereby agree to direct the Trustee, and the Trustee hereby is directed, to deposit into the Excess Net WAC Rate Reserve Account the amounts described above on each Distribution Date as to which there is any Excess Pool Net WAC Rate Amount rather than distributing such amounts to the Class A Certificateholders, as applicable. By accepting a Class A Certificate, each such Certificateholder further agrees that such direction is given for good and valuable consideration, the receipt and sufficiency of which is acknowledged by such acceptance. Amounts on deposit in the Excess Net WAC Rate Reserve Account will remain uninvested. For federal tax return and information reporting, the right of the Class A Certificateholders and the Class CE Certificates to receive payments from the Excess Net WAC Rate Reserve Account in respect of any Excess Group Net WAC Rate Amount shall be assigned a value of zero. -87- ARTICLE IV PAYMENTS TO CERTIFICATEHOLDERS SECTION 4.01. Distributions. (a)(1) On each Distribution Date, the following amounts, in the following order of priority, shall be distributed by REMIC I to REMIC II on account of the REMIC I Regular Interests or withdrawn from the Distribution Account and distributed to the holders of the Class R Certificates (in respect of the Class R-I Interest), as the case may be: (i) to the Holders of REMIC I Regular Interest I-LTAA, REMIC I Regular Interest I-LTA1, REMIC I Regular Interest I-LTA2, REMIC I Regular Interest I-LTM1, REMIC I Regular Interest I-LTM2, REMIC Regular Interest I-LTM3, REMIC Regular Interest I-LTM4, REMIC I Regular Interest I-LTM5, REMIC I Regular Interest I-LTM6, REMIC I Regular Interest I-LTZZ and REMIC I Regular Interest I-LTP, PRO RATA, in an amount equal to (A) the Uncertificated Interest for each such REMIC I Regular Interest for such Distribution Date, plus (B) any amounts in respect thereof remaining unpaid from previous Distribution Dates.

Such distributions shall not be applied to reduce the Certificate Principal Balance of the Class P Certificates. (c) All distributions made with respect to each Class of Certificates on each Distribution Date shall be allocated PRO RATA among the outstanding Certificates in such Class based on their respective Percentage Interests. Distributions in respect of each Class of Certificates on each Distribution Date will be made to the Holders of the respective Class of record on the related Record Date (except as otherwise provided in Section 4.01(e) or Section 9.01 respecting the final distribution on such Class), based on the aggregate Percentage Interest represented by their respective Certificates, and shall be made by wire transfer of immediately available funds to the account of any such Holder at a bank or other entity having appropriate facilities therefor, if such Holder shall have so notified the Trustee in writing at least five Business Days prior to the Record Date immediately prior to such Distribution Date and is the registered owner of Certificates having an initial aggregate Certificate Principal Balance or Notional Amount that is in excess of the lesser of (i) $5,000,000 or (ii) two-thirds of the initial Certificate Principal Balance or Notional Amount of such Class of Certificates, or otherwise by check mailed by first class mail to the address of such Holder appearing in the Certificate Register.

Each distribution with respect to a Book-Entry Certificate shall be paid to the Depository, as Holder thereof, and the Depository shall be responsible for crediting the amount of such distribution to the accounts of its Depository Participants in accordance with its normal procedures. Each Depository Participant shall be responsible for disbursing such distribution to the Certificate Owners that it represents and to each indirect participating brokerage firm (a "brokerage firm" or "indirect participating firm") for which it acts as agent. Each brokerage firm shall be responsible for disbursing funds to the Certificate Owners that it represents. None of the Trustee, the Depositor or the Master Servicer shall have any responsibility therefor except as otherwise provided by this Agreement or applicable law. (d) The rights of the Certificateholders to receive distributions in respect of the Certificates, and all interests of the Certificateholders in such distributions, shall be as set forth in this Agreement. None of the Holders of any Class of Certificates, the Trustee or the Master Servicer shall in any way be responsible or liable to the Holders of any other Class of Certificates in respect of amounts properly previously distributed on the Certificates. -95- (e) Except as otherwise provided in Section 9.01, whenever the Trustee expects that the final distribution with respect to any Class of Certificates will be made on the next Distribution Date, the Trustee shall, no later than three (3) days before the related Distribution Date, mail to each Holder on such date of such Class of Certificates a notice to the effect that: (i) the Trustee expects that the final distribution with respect to such Class of Certificates will be made on such Distribution Date but only upon presentation and surrender of such Certificates at the office of the Trustee therein specified, and (ii) no interest shall accrue on such Certificates from and after the end of the related Accrual Period. Any funds not distributed to any Holder or Holders of Certificates of such Class on such Distribution Date because of the failure of such Holder or Holders to tender their Certificates shall, on such date, be set aside and held in trust by the Trustee and credited to the account of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to this Section 4.01(e) shall not have been surrendered for cancellation within six months after the time specified in such notice, the Trustee shall mail a second notice to the remaining non-tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Trustee shall, directly or through an agent, mail a final notice to the remaining non-tendering Certificateholders concerning surrender of their Certificates but shall continue to hold any remaining funds for the benefit of non-tendering Certificateholders. The costs and expenses of maintaining the funds in trust and of contacting such Certificateholders shall be paid out of the assets remaining in the Trust Fund. If within one year after the final notice any such Certificates shall not have been surrendered for cancellation, the Trustee shall pay to UBS Warburg LLC all such amounts, and all rights of non-tendering Certificateholders in or to such amounts shall thereupon cease. No interest shall accrue or be payable to any Certificateholder on any amount held in trust by the Trustee as a result of such Certificateholder's failure to surrender its Certificate(s) for final payment thereof in accordance with this Section 4.01(e). Any such amounts held in trust by the Trustee shall be held in an Eligible Account and the Trustee may direct any depository institution maintaining such account to invest the funds in one or more Permitted Investments. All income and gain realized from the investment of funds deposited in such accounts held in trust by the Trustee shall be for the benefit of the Trustee; provided, however, that the Trustee shall deposit in such account the amount of any loss of principal incurred in respect of any such Permitted Investment made with funds in such accounts immediately upon the realization of such loss. (f) Notwithstanding anything to the contrary herein, (i) in no event shall the Certificate Principal Balance of a Class A Certificate or a Mezzanine Certificate be reduced more than once in respect of any particular amount both (a) allocated to such Certificate in respect of Realized Losses pursuant to Section 4.04 and (b) distributed to the Holder of such Certificate in reduction of the Certificate Principal Balance thereof pursuant to this Section 4.01 from Net Monthly Excess Cashflow and (ii) in no event shall the Uncertificated Balance of a REMIC I Regular Interest be reduced more than once in respect of any particular amount both (a) allocated to such REMIC I Regular Interest in respect of Realized Losses pursuant to Section 4.04 and (b) distributed on such -96- REMIC I Regular Interest in reduction of the Uncertificated Balance thereof pursuant to this Section 4.01.

The Trustee shall not be responsible to recompute, recalculate or verify any information provided to it by the Master Servicer. -100- (b) The amount of Advances to be made by the Master Servicer for any Distribution Date shall equal, subject to Section 4.03(d), the sum of (i) the aggregate amount of Monthly Payments (with each interest portion thereof net of the related Servicing Fee), due on the related Due Date in respect of the Mortgage Loans, which Monthly Payments were delinquent as of the close of business on the related Determination Date and (ii) with respect to each REO Property, which REO Property was acquired during or prior to the related Prepayment Period and as to which REO Property an REO Disposition did not occur during the related Prepayment Period, an amount equal to the excess, if any, of the REO Imputed Interest on such REO Property for the most recently ended calendar month, over the net income from such REO Property transferred to the Distribution Account pursuant to Section 3.23 for distribution on such Distribution Date. For purposes of the preceding sentence, the Monthly Payment on each Balloon Mortgage Loan with a delinquent Balloon Payment is equal to the assumed monthly payment that would have been due on the related Due Date based on the original principal amortization schedule for the such Balloon Mortgage Loan. By 1:00 p.m. New York time on the Master Servicer Remittance Date, the Master Servicer shall remit in immediately available funds to the Trustee for deposit in the Distribution Account an amount equal to the aggregate amount of Advances, if any, to be made in respect of the Mortgage Loans and REO Properties for the related Distribution Date either (i) from its own funds or (ii) from the Collection Account, to the extent of funds held therein for future distribution (in which case it will cause to be made an appropriate entry in the records of Collection Account that amounts held for future distribution have been, as permitted by this Section 4.03, used by the Master Servicer in discharge of any such Advance) or (iii) in the form of any combination of (i) and (ii) aggregating the total amount of Advances to be made by the Master Servicer with respect to the Mortgage Loans and REO Properties. Any amounts held for future distribution and so used shall be appropriately reflected in the Master Servicer's records and replaced by the Master Servicer by deposit in the Collection Account on or before any future Master Servicer Remittance Date to the extent that the Available Funds for the related Distribution Date (determined without regard to Advances to be made on the Master Servicer Remittance Date) shall be less than the total amount that would be distributed to the Certificateholders pursuant to Section 4.01 on such Distribution Date if such amounts held for future distributions had not been so used to make Advances. The Trustee will provide notice to the Master Servicer and the NIMS Insurer by telecopy by the close of business on the third Business Day prior to the Distribution Date in the event that the amount remitted by the Master Servicer to the Trustee on such date is less than the Advances required to be made by the Master Servicer for the related Distribution Date. (c) The obligation of the Master Servicer to make such Advances is mandatory, notwithstanding any other provision of this Agreement but subject to (d) below, and, with respect to any Mortgage Loan or REO Property, shall continue until a Final Recovery Determination in connection therewith or the removal thereof from the Trust Fund pursuant to any applicable provision of this Agreement, except as otherwise provided in this Section. (d) Notwithstanding anything herein to the contrary, no Advance or Servicing Advance shall be required to be made hereunder by the Master Servicer if such Advance or Servicing Advance would, if made, constitute a Nonrecoverable Advance or Nonrecoverable Servicing Advance, respectively. The determination by the Master Servicer that it has made a Nonrecoverable Advance or a Nonrecoverable Servicing Advance or that any proposed Advance or Servicing -101- Advance, if made, would constitute a Nonrecoverable Advance or Nonrecoverable Servicing Advance, respectively, shall be evidenced by an Officers' Certificate of the Master Servicer delivered to the Depositor, the NIMS Insurer and the Trustee. SECTION 4.04. Allocation of Realized Losses. (a) Prior to each Determination Date, the Master Servicer shall determine as to each Mortgage Loan and REO Property: (i) the total amount of Realized Losses, if any, incurred in connection with any Final Recovery Determinations made during the related Prepayment Period; and (ii) the respective portions of such Realized Losses allocable to interest and allocable to principal. Prior to each Determination Date, the Master Servicer shall also determine as to each Mortgage Loan: (i) the total amount of Realized Losses, if any, incurred in connection with any Deficient Valuations made during the related Prepayment Period; and (ii) the total amount of Realized Losses, if any, incurred in connection with Debt Service Reductions in respect of Monthly Payments due during the related Due Period. The information described in the preceding sentence that is to be supplied by the Master Servicer shall be evidenced by an Officers' Certificate delivered to the Trustee by the Master Servicer prior to the Determination Date immediately following the end of the Prepayment Period during which any such Realized Loss was incurred. (b) All Realized Losses on the Mortgage Loans shall be allocated by the Trustee on each Distribution Date as follows: first, to Net Monthly Excess Cashflow; second, to the Class CE Certificates, until the Certificate Principal Balance thereof has been reduced to zero; third, to the Class M-6 Certificates, until the Certificate Principal Balance thereof has been reduced to zero; fourth, to the Class M-5 Certificates, until the Certificate Principal Balance thereof has been reduced to zero; fifth, to the Class M-4 Certificates, until the Certificate Principal Balance thereof has been reduced to zero; sixth, to the Class M-3 Certificates, until the Certificate Principal Balance thereof has been reduced to zero; seventh, to the Class M-2 Certificates, until the Certificate Principal Balance thereof has been reduced to zero; and eighth, to the Class M-1 Certificates, until the Certificate Principal Balance thereof has been reduced to zero. All Realized Losses to be allocated to the Certificate Principal Balances of all Classes on any Distribution Date shall be so allocated after the actual distributions to be made on such date as provided above. All references above to the Certificate Principal Balance of any Class of Certificates shall be to the Certificate Principal Balance of such Class immediately prior to the relevant Distribution Date, before reduction thereof by any Realized Losses, in each case to be allocated to such Class of Certificates, on such Distribution Date. Any allocation of Realized Losses to a Mezzanine Certificate on any Distribution Date shall be made by reducing the Certificate Principal Balance thereof by the amount so allocated; any allocation of Realized Losses to a Class CE Certificate shall be made by reducing the amount otherwise payable in respect thereof pursuant to Section 4.01(d)(xv). No allocations of any Realized Losses shall be made to the Certificate Principal Balances of the Class A Certificates or the Class P Certificates. As used herein, an allocation of a Realized Loss on a "PRO RATA basis" among two or more specified Classes of Certificates means an allocation on a PRO RATA basis, among the various Classes so specified, to each such Class of Certificates on the basis of their then outstanding Certificate Principal Balances prior to giving effect to distributions to be made on such Distribution -102- 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. (c) All Realized Losses on the Mortgage Loans shall be allocated by the Trustee on each Distribution Date to the following REMIC I Regular Interests in the specified percentages, as follows: first, to Uncertificated Interest payable to the REMIC I Regular Interest I-LTAA and REMIC I Regular Interest I-LTZZ up to an aggregate amount equal to the REMIC I Interest Loss Allocation Amount, 98% and 2%, respectively; second, to the Uncertificated Balances of REMIC I Regular Interest I-LTAA and REMIC I Regular Interest I-LTZZ up to an aggregate amount equal to the REMIC I Principal Loss Allocation Amount, 98% and 2%, respectively; third, to the Uncertificated Balances of REMIC I Regular Interest I-LTAA, REMIC I Regular Interest I-LTM6 and REMIC I Regular Interest I-LTZZ, 98%, 1% and 1%, respectively, until the Uncertificated Balance of REMIC I Regular Interest I-LTM6 has been reduced to zero; fourth to the Uncertificated Balances of REMIC I Regular Interest I-LTAA, REMIC I Regular Interest I-LTM5 and REMIC I Regular Interest I-LTZZ, 98%, 1% and 1%, respectively, until the Uncertificated Balance of REMIC I Regular Interest I-LTM5 has been reduced to zero; fifth to the Uncertificated Balances of REMIC I Regular Interest I-LTAA, REMIC I Regular Interest I-LTM4 and REMIC I Regular Interest I-LTZZ, 98%, 1% and 1%, respectively, until the Uncertificated Balance of REMIC I Regular Interest I-LTM4 has been reduced to zero; sixth to the Uncertificated Balances of REMIC I Regular Interest I-LTAA, REMIC I Regular Interest I-LTM3 and REMIC I Regular Interest I-LTZZ, 98%, 1% and 1%, respectively, until the Uncertificated Balance of REMIC I Regular Interest I-LTM3 has been reduced to zero; seventh to the Uncertificated Balances of REMIC I Regular Interest I-LTAA, REMIC I Regular Interest I-LTM2 and REMIC I Regular Interest I-LTZZ, 98%, 1% and 1%, respectively, until the Uncertificated Balance of REMIC I Regular Interest I-LTM2 has been reduced to zero; and eighth, to the Uncertificated Balances of REMIC I Regular Interest I-LTAA, REMIC I Regular Interest I-LTM1 and REMIC I Regular Interest I-LTZZ, 98%, 1% and 1%, respectively, until the Uncertificated Balance of REMIC I Regular Interest I-LTM1 has been reduced to zero.

Compliance with Withholding Requirements Notwithstanding any other provision of this Agreement, the Trustee shall comply with all federal withholding requirements respecting payments to Certificateholders of interest or original issue discount that the Trustee reasonably believes are applicable under the Code. The consent of Certificateholders shall not be required for such withholding. In the event the Trustee does withhold any amount from interest or original issue discount payments or advances thereof to any Certificateholder pursuant to federal withholding requirements, the Trustee shall indicate the amount withheld to such Certificateholders. SECTION 4.06. Exchange Commission; Additional Information. (a) The Trustee and the Master Servicer shall reasonably cooperate with the Depositor in connection with satisfying the reporting requirements of the Trust Fund under the Exchange Act. The Trustee shall prepare and sign on behalf of the Trust Fund any Forms 8-K and 10-K customary for similar securities as required by the Exchange Act and the Rules and Regulations of the Commission thereunder, and the Trustee shall file (via the Securities and -103- Exchange Commission's Electronic Data Gathering and Retrieval System) such forms on behalf of the Trust Fund. The parties hereto agree that the Trustee shall have the authority to execute any Form 8-K or Form 10-K and file each such document on behalf of the Trust Fund. (b) Each Form 8-K shall be filed by the Trustee within 15 days after each Distribution Date with a copy of the Monthly Statement for such Distribution Date as an exhibit thereto. Prior to March 30th of each year (or such earlier date as may be required by the Exchange Act and the Rules and Regulations of the Commission), the Trustee shall file a Form 10-K, in substance as required by applicable law or applicable Commission staff's interpretations. Such Form 10-K shall include as exhibits the Master Servicer's annual statement of compliance described under Section 3.20 and the accountant's report described under Section 3.21, in each case to the extent they have been timely delivered to the Trustee. If they are not so timely delivered, the Trustee shall file an amended Form 10-K including such documents as exhibits reasonably promptly after they are delivered to the Trustee. The Trustee shall have no liability with respect to any failure to properly prepare or file such periodic reports resulting from or relating to (a) the Trustee's inability or failure to obtain any information not resulting from its own negligence or willful misconduct or (b) any inaccuracy in such periodic reports resulting from incorrect information provided to the Trustee by the Master Servicer in a Remittance Report or otherwise. The Form 10-K shall also include a certification in the form attached hereto as Exhibit J-1 (the "Certification"), which shall be signed by the Master Servicer. (c) In addition, the Trustee shall sign a certification (in the form attached hereto as Exhibit J-2) for the benefit of the Master Servicer and its officers, directors and Affiliates regarding certain aspects of the Certification (provided, however, that the Trustee shall not undertake an analysis of the accountant's report attached as an exhibit to the Form 10-K). In addition, (i) the Trustee shall, subject to the provisions of Sections 8.01 and 8.02, indemnify and hold harmless the Depositor and the Master Servicer and their respective officers, directors and Affiliates from and against any losses, damages, penalties, fines, forfeitures, reasonable and necessary legal fees and related costs, judgments and other costs and expenses arising out of or based upon a breach of the Trustee's obligations under this Section 4.06(b) or the Trustee's negligence, bad faith or willful misconduct in connection therewith, and (ii) the Master Servicer shall indemnify and hold harmless the Depositor, the Trustee and their respective officers, directors and Affiliates from and against any losses, damages, penalties, fines, forfeitures, reasonable and necessary legal fees and related costs, judgments and other costs and expenses arising out of or based upon a breach of the Master Servicer's obligations under this Section 4.06(b) or the Master Servicer's negligence, bad faith or willful misconduct in connection therewith. If the indemnification provided for herein is unavailable or insufficient to hold harmless the Depositor or the Master Servicer, then (i) the Trustee agrees that it shall contribute to the amount paid or payable by the Depositor or the Master Servicer, as applicable, as a result of the losses, claims, damages or liabilities of the Depositor or the Master Servicer, as applicable, in such proportion as is appropriate to reflect the relative fault of the or the Depositor or the Master Servicer, as applicable, on the one hand and the Trustee on the other in connection with a breach of the Trustee's obligations under this Section 4.06(b) or the Trustee's negligence, bad faith or willful misconduct in connection therewith and (ii) the Master Servicer agrees that it shall contribute to the amount paid or payable by the Depositor or the Trustee, as applicable, as a result of the losses, claims, damages or liabilities of the -104- Depositor or the Trustee, as applicable, in such proportion as is appropriate to reflect the relative fault of the Depositor or the Trustee, as applicable, on the one hand and the Master Servicer on the other in connection with a breach of the Master Servicer's obligations under this Section 4.06(b) or the Master Servicer's negligence, bad faith or willful misconduct in connection therewith. Notwithstanding any other provision in this Agreement to the contrary, the Master Servicer shall not have any responsibility or liability to any party relating to the certification or information prepared, certified or distributed by the Trustee or any other party other than the Master Servicer unless such information was derived from erroneous or incomplete information required to be provided by the Master Servicer under this Agreement. (d) Upon any filing with the Commission pursuant to this Section 4.06(b), the Trustee shall promptly deliver to the Depositor a copy of any executed report, statement or information. (e) Prior to January 30 of the first year in which the Trustee is able to do so under applicable law, the Trustee shall file a Form 15 Suspension Notification with respect to the Trust Fund. -105- ARTICLE V THE CERTIFICATES SECTION 5.01. The Certificates. (a) The Certificates in the aggregate will represent the entire beneficial ownership interest in the Mortgage Loans and all other assets included in REMIC I. The Certificates will be substantially in the forms annexed hereto as Exhibits A-1 through A-12. The Certificates of each Class will be issuable in registered form only, in denominations of authorized Percentage Interests as described in the definition thereof. Each Certificate will share ratably in all rights of the related Class. Upon original issue, the Certificates shall be executed by the Trustee and authenticated and delivered by the Trustee to or upon the order of the Depositor. The Certificates shall be executed by manual or facsimile signature on behalf of the Trustee by an authorized signatory. Certificates bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Trustee shall bind the Trustee notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Certificates or did not hold such offices at the date of such Certificates. No Certificate shall be entitled to any benefit under this Agreement or be valid for any purpose, unless there appears on such Certificate a certificate of authentication substantially in the form provided herein executed by the Trustee by manual signature, and such certificate of authentication shall be conclusive evidence, and the only evidence, that such Certificate has been duly authenticated and delivered hereunder. All Certificates shall be dated the date of their authentication. (b) The Class A Certificates and the Mezzanine Certificates shall initially be issued as one or more Certificates held by the Book-Entry Custodian or, if appointed to hold such Certificates as provided below, the Depository and registered in the name of the Depository or its nominee and, except as provided below, registration of such Certificates may not be transferred by the Trustee except to another Depository that agrees to hold such Certificates for the respective Certificate Owners with Ownership Interests therein. The Certificate Owners shall hold their respective Ownership Interests in and to such Certificates through the book-entry facilities of the Depository and, except as provided below, shall not be entitled to definitive, fully registered Certificates ("Definitive Certificates") in respect of such Ownership Interests. All transfers by Certificate Owners of their respective Ownership Interests in the Book-Entry Certificates shall be made in accordance with the procedures established by the Depository Participant or brokerage firm representing such Certificate Owner. Each Depository Participant shall only transfer the Ownership Interests in the Book-Entry Certificates of Certificate Owners it represents or of brokerage firms for which it acts as agent in accordance with the Depository's normal procedures. The Trustee is hereby initially appointed as the Book-Entry Custodian and hereby agrees to act as such in accordance herewith and in accordance with the agreement that it has with the Depository authorizing it to act as such. The Book-Entry Custodian may, and, if it is no longer qualified to act as such, the Book- Entry Custodian shall, appoint, by a written instrument delivered to the Depositor, the Master Servicer and the Trustee, any other transfer agent (including the Depository or any successor -106- Depository) to act as Book-Entry Custodian under such conditions as the predecessor Book-Entry Custodian and the Depository or any successor Depository may prescribe, provided that the predecessor Book-Entry Custodian shall not be relieved of any of its duties or responsibilities by reason of any such appointment of other than the Depository. If the Trustee resigns or is removed in accordance with the terms hereof, the Trustee, the successor trustee or, if it so elects, the Depository shall immediately succeed to its predecessor's duties as Book-Entry Custodian. The Depositor shall have the right to inspect, and to obtain copies of, any Certificates held as Book-Entry Certificates by the Book-Entry Custodian. The Trustee, the Master Servicer and the Depositor may for all purposes (including the making of payments due on the Book-Entry Certificates) deal with the Depository as the authorized representative of the Certificate Owners with respect to the Book-Entry Certificates for the purposes of exercising the rights of Certificateholders hereunder. The rights of Certificate Owners with respect to the Book-Entry Certificates shall be limited to those established by law and agreements between such Certificate Owners and the Depository Participants and brokerage firms representing such Certificate Owners. Multiple requests and directions from, and votes of, the Depository as Holder of the Book-Entry Certificates with respect to any particular matter shall not be deemed inconsistent if they are made with respect to different Certificate Owners. The Trustee may establish a reasonable record date in connection with solicitations of consents from or voting by Certificateholders and shall give notice to the Depository of such record date. If (i)(A) the Depositor advises the Trustee in writing that the Depository is no longer willing or able to properly discharge its responsibilities as Depository, and (B) the Depositor is unable to locate a qualified successor, (ii) the Depositor at its option advises the Trustee in writing that it elects to terminate the book-entry system through the Depository or (iii) after the occurrence of a Master Servicer Event of Default, Certificate Owners representing in the aggregate not less than 51% of the Ownership Interests of the Book-Entry Certificates advise the Trustee through the Depository, in writing, that the continuation of a book-entry system through the Depository is no longer in the best interests of the Certificate Owners, the Trustee shall notify all Certificate Owners, through the Depository, of the occurrence of any such event and of the availability of Definitive Certificates to Certificate Owners requesting the same. Upon surrender to the Trustee of the Book- Entry Certificates by the Book-Entry Custodian or the Depository, as applicable, accompanied by registration instructions from the Depository for registration of transfer, the Trustee shall cause the Definitive Certificates to be issued. Such Definitive Certificates will be issued in minimum denominations of $50,000, except that any beneficial ownership that was represented by a Book- Entry Certificate in an amount less than $50,000 immediately prior to the issuance of a Definitive Certificate shall be issued in a minimum denomination equal to the amount represented by such Book-Entry Certificate. None of the Depositor, the Master Servicer, the Trustee shall be liable for any delay in the delivery of such instructions and may conclusively rely on, and shall be protected in relying on, such instructions. Upon the issuance of Definitive Certificates all references herein to obligations imposed upon or to be performed by the Depository shall be deemed to be imposed upon and performed by the Trustee, to the extent applicable with respect to such Definitive Certificates, and the Trustee shall recognize the Holders of the Definitive Certificates as Certificateholders hereunder. -107- SECTION 5.02. Registration of Transfer and Exchange of Certificates. (a) The Trustee shall cause to be kept at one of the offices or agencies to be appointed by the Trustee in accordance with the provisions of Section 8.11, a Certificate Register for the Certificates in which, subject to such reasonable regulations as it may prescribe, the Trustee shall provide for the registration of Certificates and of transfers and exchanges of Certificates as herein provided. (b) No transfer of any Class CE Certificate, Class P Certificate or Residual Certificate shall be made unless that transfer is made pursuant to an effective registration statement under the Securities Act of 1933, as amended (the "1933 Act"), and effective registration or qualification under applicable state securities laws, or is made in a transaction that does not require such registration or qualification. In the event that such a transfer of a Class CE Certificate, Class P Certificate or Residual Certificate is to be made without registration or qualification (other than in connection with the initial transfer of any such Certificate by the Depositor to an affiliate of the Depositor), the Trustee shall require receipt of: (i) if such transfer is purportedly being made in reliance upon Rule 144A under the 1933 Act, written certifications from the Certificateholder desiring to effect the transfer and from such Certificateholder's prospective transferee, substantially in the forms attached hereto as Exhibit F-1; and (ii) in all other cases, an Opinion of Counsel satisfactory to it that such transfer may be made without such registration or qualification (which Opinion of Counsel shall not be an expense of the Trust Fund or of the Depositor, the Trustee, the Master Servicer in its capacity as such or any Sub-Servicer), together with copies of the written certification(s) of the Certificateholder desiring to effect the transfer and/or such Certificateholder's prospective transferee upon which such Opinion of Counsel is based, if any. None of the Depositor, the Master Servicer or the Trustee is obligated to register or qualify any such Certificates under the 1933 Act or any other securities laws or to take any action not otherwise required under this Agreement to permit the transfer of such Certificates without registration or qualification. Any Certificateholder desiring to effect the transfer of any such Certificate shall, and does hereby agree to, indemnify the Trustee, the Depositor and the Master Servicer against any liability that may result if the transfer is not so exempt or is not made in accordance with such federal and state laws. (c) No transfer of a Class CE Certificate, Class P Certificate or Residual Certificate or any interest therein shall be made to any Plan subject to ERISA or Section 4975 of the Code, any Person acting, directly or indirectly, on behalf of any such Plan or any Person acquiring such Certificates with "Plan Assets" of a Plan within the meaning of the Department of Labor regulation promulgated at 29 C. F. R. ss. 2510.3-101 ("Plan Assets"), as certified by such transferee in the form of Exhibit G, unless the Depositor, the Trustee and the Master Servicer are provided with an Opinion of Counsel which establishes to the satisfaction of the Depositor, the Trustee and the Master Servicer that the purchase of such Certificates is permissible under applicable law, will not constitute or result in any prohibited transaction under ERISA or Section 4975 of the Code and will not subject the Depositor, the Master Servicer, the NIMS Insurer, the Trustee or the Trust Fund to any obligation or liability (including obligations or liabilities under ERISA or Section 4975 of the Code) in addition to those undertaken in this Agreement, which Opinion of Counsel shall not be an expense of the Depositor, the Master Servicer, the Trustee or the Trust Fund. Neither an Opinion of Counsel nor any certification will be required in connection with the initial transfer of any such Certificate by the Depositor to an affiliate of the Depositor (in which case, the Depositor or any -108- affiliate thereof shall have deemed to have represented that such affiliate is not a Plan or a Person investing Plan Assets) and the Trustee shall be entitled to conclusively rely upon a representation (which, upon the request of the Trustee, shall be a written representation) from the Depositor of the status of such transferee as an affiliate of the Depositor. Each beneficial owner of a Mezzanine Certificates or any interest therein shall be deemed to have represented, by virtue of its acquisition or holding of that certificate or interest therein, that either (i) it is not a Plan investor, (ii) it has acquired and is holding such Mezzanine Certificates in reliance on the Underwriters' Exemption, and that it understands that there are certain conditions to the availability of the Underwriters' Exemption, including that the Mezzanine Certificates must be rated, at the time of purchase, not lower than" BBB-" (or its equivalent) by Fitch, Moody's or S&P or (iii) (1) it is an insurance company, (2) the source of funds used to acquire or hold the certificate or interest therein is an "insurance company general account," as such term is defined in PTCE 95-60, and (3) the conditions in Sections I and III of PTCE 95-60 have been satisfied. If any Class CE Certificate, Class P Certificate or Residual Certificate or any interest therein is acquired or held in violation of the provisions of the preceding paragraph, the next preceding permitted beneficial owner will be treated as the beneficial owner of that Certificate retroactive to the date of transfer to the purported beneficial owner. Any purported beneficial owner whose acquisition or holding of any such Certificate or interest therein was effected in violation of the provisions of the preceding paragraph shall indemnify and hold harmless the Depositor, the Master Servicer, the NIMS Insurer, the Trustee and the Trust Fund from and against any and all liabilities, claims, costs or expenses incurred by those parties as a result of that acquisition or holding. (d)(i) Each Person who has or who acquires any Ownership Interest in a Residual Certificate shall be deemed by the acceptance or acquisition of such Ownership Interest to have agreed to be bound by the following provisions and to have irrevocably authorized the Trustee or its designee under clause (iii)(A) below to deliver payments to a Person other than such Person and to negotiate the terms of any mandatory sale under clause (iii)(B) below and to execute all instruments of Transfer and to do all other things necessary in connection with any such sale. The rights of each Person acquiring any Ownership Interest in a Residual Certificate are expressly subject to the following provisions: (A) Each Person holding or acquiring any Ownership Interest in a Residual Certificate shall be a Permitted Transferee and shall promptly notify the Trustee of any change or impending change in its status as a Permitted Transferee. (B) In connection with any proposed Transfer of any Ownership Interest in a Residual Certificate, the Trustee shall require delivery to it, and shall not register the Transfer of any Residual Certificate until its receipt of, an affidavit and agreement (a "Transfer Affidavit and Agreement," in the form attached hereto as Exhibit F-2) from the proposed Transferee, in form and substance satisfactory to the Trustee, representing and warranting, among other things, that such Transferee is a Permitted Transferee, that it is not acquiring its Ownership Interest in the Residual Certificate that is the subject of the proposed -109- Transfer as a nominee, trustee or agent for any Person that is not a Permitted Transferee, that for so long as it retains its Ownership Interest in a Residual Certificate, it will endeavor to remain a Permitted Transferee, and that it has reviewed the provisions of this Section 5.02(d) and agrees to be bound by them. (C) Notwithstanding the delivery of a Transfer Affidavit and Agreement by a proposed Transferee under clause (B) above, if a Responsible Officer of the Trustee who is assigned to this transaction has actual knowledge that the proposed Transferee is not a Permitted Transferee, no Transfer of an Ownership Interest in a Residual Certificate to such proposed Transferee shall be effected. (D) Each Person holding or acquiring any Ownership Interest in a Residual Certificate shall agree (x) to require a Transfer Affidavit and Agreement in the form attached hereto as Exhibit F-2 from any other Person to whom such Person attempts to transfer its Ownership Interest in a Residual Certificate and (y) not to transfer its Ownership Interest unless it provides a Transferor Affidavit (in the form attached hereto as Exhibit F-2) to the Trustee stating that, among other things, it has no actual knowledge that such other Person is not a Permitted Transferee. (E) Each Person holding or acquiring an Ownership Interest in a Residual Certificate, by purchasing an Ownership Interest in such Certificate, agrees to give the Trustee written notice that it is a "pass-through interest holder" within the meaning of temporary Treasury regulation Section 1.67-3T(a)(2)(i)(A) immediately upon acquiring an Ownership Interest in a Residual Certificate, if it is, or is holding an Ownership Interest in a Residual Certificate on behalf of, a "pass-through interest holder." (ii) The Trustee will register the Transfer of any Residual Certificate only if it shall have received the Transfer Affidavit and Agreement and all of such other documents as shall have been reasonably required by the Trustee as a condition to such registration. In addition, no Transfer of a Residual Certificate shall be made unless the Trustee shall have received a representation letter from the Transferee of such Certificate to the effect that such Transferee is a Permitted Transferee. (iii)(A) If any purported Transferee shall become a Holder of a Residual Certificate in violation of the provisions of this Section 5.02(d), then the last preceding Permitted Transferee shall be restored, to the extent permitted by law, to all rights as holder thereof retroactive to the date of registration of such Transfer of such Residual Certificate. The Trustee shall be under no liability to any Person for any registration of Transfer of a Residual Certificate that is in fact not permitted by this Section 5.02(d) or for making any payments due on such Certificate to the holder thereof or for taking any other action with respect to such holder under the provisions of this Agreement. (B) If any purported Transferee shall become a holder of a Residual Certificate in violation of the restrictions in this Section 5.02(d) and to the extent that the retroactive restoration of the rights of the holder of such Residual Certificate as described in clause (iii)(A) above shall be invalid, illegal or unenforceable, then the Trustee shall have the right, -110- without notice to the holder or any prior holder of such Residual Certificate, to sell such Residual Certificate to a purchaser selected by the Trustee on such terms as the Trustee may choose. Such purported Transferee shall promptly endorse and deliver each Residual Certificate in accordance with the instructions of the Trustee. Such purchaser may be the Trustee itself or any Affiliate of the Trustee. The proceeds of such sale, net of the commissions (which may include commissions payable to the Trustee or its Affiliates), expenses and taxes due, if any, will be remitted by the Trustee to such purported Transferee. The terms and conditions of any sale under this clause (iii)(B) shall be determined in the sole discretion of the Trustee, and the Trustee shall not be liable to any Person having an Ownership Interest in a Residual Certificate as a result of its exercise of such discretion. (iv) The Trustee shall make available to the Internal Revenue Service and those Persons specified by the REMIC Provisions all information necessary to compute any tax imposed (A) as a result of the Transfer of an Ownership Interest in a Residual Certificate to any Person who is a Disqualified Organization, including the information described in Treasury regulations sections 1.860D-1(b)(5) and 1.860E-2(a)(5) with respect to the "excess inclusions" of such Residual Certificate and (B) as a result of any regulated investment company, real estate investment trust, common Trust, partnership, trust, estate or organization described in Section 1381 of the Code that holds an Ownership Interest in a Residual Certificate having as among its record holders at any time any Person which is a Disqualified Organization. Reasonable compensation for providing such information may be accepted by the Trustee. (v) The provisions of this Section 5.02(d) set forth prior to this subsection (v) may be modified, added to or eliminated, provided that there shall have been delivered to the Trustee and the NIMS Insurer at the expense of the party seeking to modify, add to or eliminate any such provision the following: (A) written notification from each Rating Agency to the effect that the modification, addition to or elimination of such provisions will not cause such Rating Agency to downgrade its then-current ratings of any Class of Certificates; and (B) an Opinion of Counsel, in form and substance satisfactory to the Trustee and the NIMS Insurer, to the effect that such modification of, addition to or elimination of such provisions will not cause any Trust REMIC to cease to qualify as a REMIC and will not cause any Trust REMIC to be subject to an entity-level tax caused by the Transfer of any Residual Certificate to a Person that is not a Permitted Transferee or a Person other than the prospective transferee to be subject to a REMIC-tax caused by the Transfer of a Residual Certificate to a Person that is not a Permitted Transferee. The Trustee shall forward to the NIMS Insurer a copy of the items delivered to it pursuant to (A) and (B) above. (e) Subject to the preceding subsections, upon surrender for registration of transfer of any Certificate at any office or agency of the Trustee maintained for such purpose pursuant to Section 8.11, the Trustee shall execute, authenticate and deliver, in the name of the -111- designated Transferee or Transferees, one or more new Certificates of the same Class of a like aggregate Percentage Interest. (f) At the option of the Holder thereof, any Certificate may be exchanged for other Certificates of the same Class with authorized denominations and a like aggregate Percentage Interest, upon surrender of such Certificate to be exchanged at any office or agency of the Trustee maintained for such purpose pursuant to Section 8.11. Whenever any Certificates are so surrendered for exchange, the Trustee shall execute, authenticate and deliver, the Certificates which the Certificateholder making the exchange is entitled to receive. Every Certificate presented or surrendered for transfer or exchange shall (if so required by the Trustee) be duly endorsed by, or be accompanied by a written instrument of transfer in the form satisfactory to the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing. (g) No service charge to the Certificateholders shall be made for any transfer or exchange of Certificates, but the Trustee may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any transfer or exchange of Certificates. (h) All Certificates surrendered for transfer and exchange shall be canceled and destroyed by the Trustee in accordance with its customary procedures. SECTION 5.03. Mutilated, Destroyed, Lost or Stolen Certificates. If (i) any mutilated Certificate is surrendered to the Trustee, or the Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Certificate, and (ii) there is delivered to the Trustee and the NIMS Insurer such security or indemnity as may be required by it to save it harmless, then, in the absence of actual knowledge by the Trustee that such Certificate has been acquired by a bona fide purchaser or the Trustee shall execute, authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new Certificate of the same Class and of like denomination and Percentage Interest. Upon the issuance of any new Certificate under this Section, the Trustee may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith. Any replacement Certificate issued pursuant to this Section shall constitute complete and indefeasible evidence of ownership in the applicable REMIC created hereunder, as if originally issued, whether or not the lost, stolen or destroyed Certificate shall be found at any time. SECTION 5.04. Persons Deemed Owners. The Depositor, the Master Servicer, the NIMS Insurer, the Trustee and any agent of any of them may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions pursuant to Section 4.01 and for all other purposes whatsoever, and none of the Depositor, the Master Servicer, the NIMS Insurer, the Trustee or any agent of any of them shall be affected by notice to the contrary.

Liability of the Depositor and the Master Servicer. The Depositor and the Master Servicer each shall be liable in accordance herewith only to the extent of the obligations specifically imposed by this Agreement upon them in their respective capacities as Depositor and Master Servicer and undertaken hereunder by the Depositor and the Master Servicer herein. SECTION 6.02. Merger or Consolidation of the Depositor or the Master Servicer. Subject to the following paragraph, the Depositor will keep in full effect its existence, rights and franchises as a corporation under the laws of the jurisdiction of its incorporation. Subject to the following paragraph, the Master Servicer will keep in full effect its existence, rights and franchises as a corporation under the laws of the jurisdiction of its incorporation. The Depositor and the Master Servicer each 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 respective duties under this Agreement. The Depositor or the Master Servicer may be merged or consolidated with or into any Person, or transfer all or substantially all of its assets to any Person, in which case any Person resulting from any merger or consolidation to which the Depositor or the Master Servicer shall be a party, or any Person succeeding to the business of the Depositor or the Master Servicer, shall be the successor of the Depositor or the Master Servicer, as the case may be, hereunder, without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding; provided, however, that the successor or surviving Person to the Master Servicer shall be qualified to service mortgage loans on behalf of Fannie Mae or Freddie Mac; and provided further that the Rating Agencies' ratings of the Class A Certificates, the Class S Certificates and the Mezzanine Certificates in effect immediately prior to such merger or consolidation will not be qualified, reduced or withdrawn as a result thereof (as evidenced by a letter to such effect from the Rating Agencies).

The Master Servicer shall immediately notify the NIMS Insurer and each Certificateholder if a claim is made that may result -114- in such claims, losses, penalties, fines, forfeitures, legal fees or related costs, judgments, or any other costs, fees and expenses, and the Master Servicer shall assume (with the consent of the Trustee) the defense of any such claim and pay all expenses in connection therewith, including reasonable counsel fees, and promptly pay, discharge and satisfy any judgment or decree which may be entered against the NIMS Insurer and/or the Certificateholder in respect of such claim.

Neither the Depositor, the NIMS Insurer nor the Master Servicer shall be under any obligation to appear in, prosecute or defend any legal action unless such action is related to its respective duties under this Agreement and, in its opinion, does not involve it in any expense or liability; provided, however, that each of the Depositor, the NIMS Insurer and the Master Servicer may in its discretion undertake any such action which it may deem necessary or desirable with respect to this Agreement and the rights and duties of the parties hereto and the interests of the Certificateholders hereunder. In such event, unless the Depositor or the Master Servicer acts without the consent of Holders of Certificates entitled to at least 51% of the Voting Rights, the legal expenses and costs of such action and any liability resulting therefrom (except any loss, liability or expense incurred by reason of willful misfeasance, bad faith or gross negligence in the performance of duties hereunder or by reason of reckless disregard of obligations and duties hereunder) shall be expenses, costs and liabilities of the Trust Fund, and the Depositor, the NIMS Insurer and the Master Servicer shall be entitled to be reimbursed therefor from the Collection Account as and to the extent provided in Section 3.11, any such right of reimbursement being prior to the rights of the Certificateholders to receive any amount in the Collection Account. -115- SECTION 6.04. Limitation on Resignation of the Master Servicer. The Master Servicer shall not resign from the obligations and duties hereby imposed on it except upon determination that its duties hereunder are no longer permissible under applicable law. Any such determination pursuant to the preceding sentence permitting the resignation of the Master Servicer shall be evidenced by an Opinion of Counsel to such effect obtained at the expense of the Master Servicer and delivered to the Trustee and the NIMS Insurer. No resignation of the Master Servicer shall become effective until the Trustee or a successor servicer acceptable to the NIMS Insurer shall have assumed the Master Servicer's responsibilities, duties, liabilities (other than those liabilities arising prior to the appointment of such successor) and obligations under this Agreement. Any such resignation shall not relieve the Master Servicer of responsibility for any of the obligations specified in Sections 7.01 and 7.02 as obligations that survive the resignation or termination of the Master Servicer. Except as expressly provided herein, the Master Servicer shall not assign or transfer any of its rights, benefits or privileges hereunder to any other Person, or delegate to or subcontract with, or authorize or appoint any other Person to perform any of the duties, covenants or obligations to be performed by the Master Servicer hereunder. The foregoing prohibition on assignment shall not prohibit the Master Servicer from designating a Sub-Servicer as payee of any indemnification amount payable to the Master Servicer hereunder; provided, however, that as provided in Section 3.06 hereof, no Sub-Servicer shall be a third-party beneficiary hereunder and the parties hereto shall not be required to recognize any Sub-Servicer as an indemnitee under this Agreement. If, pursuant to any provision hereof, the duties of the Master Servicer are transferred to a successor master servicer, the entire amount of the Servicing Fee and other compensation payable to the Master Servicer pursuant hereto shall thereafter be payable to such successor master servicer. SECTION 6.05. Rights of the Depositor in Respect of the Master Servicer. The Master Servicer shall afford (and any Sub-Servicing Agreement shall provide that each Sub-Servicer shall afford) the Depositor, the NIMS Insurer and the Trustee, upon reasonable notice, during normal business hours, access to all records maintained by the Master Servicer (and any such Sub-Servicer) in respect of the Master Servicer's rights and obligations hereunder and access to officers of the Master Servicer (and those of any such Sub-Servicer) responsible for such obligations. Upon request, the Master Servicer shall furnish to the Depositor, the NIMS Insurer and the Trustee its (and any such Sub-Servicer's) most recent financial statements and such other information relating to the Master Servicer's capacity to perform its obligations under this Agreement as it possesses (and that any such Sub-Servicer possesses). To the extent such information is not otherwise available to the public, the Depositor, the NIMS Insurer and the Trustee shall not disseminate any information obtained pursuant to the preceding two sentences without the Master Servicer's written consent, except as required pursuant to this Agreement or to the extent that it is appropriate to do so (i) in working with legal counsel, auditors, taxing authorities or other governmental agencies or (ii) pursuant to any law, rule, regulation, order, judgment, writ, injunction or decree of any court or governmental authority having jurisdiction over the Depositor and the Trustee or the Trust Fund, and in any case, the Depositor, the NIMS Insurer or the Trustee as the case may be, shall use its best efforts to assure the confidentiality of any such disseminated non-public information. The Depositor may, but is not obligated to, enforce the obligations of the -116- Master Servicer under this Agreement and may, but is not obligated to, perform, or cause a designee to perform, any defaulted obligation of the Master Servicer under this Agreement or exercise the rights of the Master Servicer under this Agreement; provided that the Master Servicer shall not be relieved of any of its obligations under this Agreement by virtue of such performance by the Depositor or its designee. The Depositor shall not have any responsibility or liability for any action or failure to act by the Master Servicer and is not obligated to supervise the performance of the Master Servicer under this Agreement or otherwise. -117- ARTICLE VII DEFAULT SECTION 7.01. Master Servicer Events of Default. (a) "Master Servicer Event of Default," wherever used herein, means any one of the following events: (i) any failure by the Master Servicer to remit to the Trustee for distribution to the Certificateholders any payment (other than an Advance required to be made from its own funds on any Master Servicer Remittance Date pursuant to Section 4.03) required to be made under the terms of the Certificates and this Agreement which continues unremedied for a period of one Business Day after the date upon which written notice of such failure, requiring the same to be remedied, shall have been given to the Master Servicer by the Depositor or the Trustee (in which case notice shall be provided by telecopy), or to the Master Servicer, the Depositor and the Trustee by the NIMS Insurer or the Holders of Certificates entitled to at least 25% of the Voting Rights; or (ii) any failure on the part of the Master Servicer duly to observe or perform in any material respect any other of the covenants or agreements on the part of the Master Servicer contained in this Agreement, or the breach by the Master Servicer of any representation and warranty contained in Section 2.05, which continues unremedied for a period of 30 days (or if such failure or breach cannot be remedied within 30 days, then such remedy shall have been commenced within 30 days and diligently pursued thereafter; provided, however, that in no event shall such failure or breach be allowed to exist for a period of greater than 90 days) after the earlier of (i) the date on which written notice of such failure, requiring the same to be remedied, shall have been given to the Master Servicer by the Depositor, the Trustee or to the Master Servicer, the Depositor and the Trustee by the NIMS Insurer or the Holders of Certificates entitled to at least 25% of the Voting Rights and (ii) actual knowledge of such failure by a Servicing Officer of the Master Servicer; or (iii) a decree or order of a court or agency or supervisory authority having jurisdiction in the premises in an involuntary case under any present or future federal or state bankruptcy, insolvency or similar law or the appointment of a conservator or receiver or liquidator in any insolvency, readjustment of debt, marshalling of assets and liabilities or similar proceeding, or for the winding-up or liquidation of its affairs, shall have been entered against the Master Servicer and such decree or order shall have remained in force undischarged or unstayed for a period of 90 days; or (iv) the Master 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 it or of or relating to all or substantially all of its property; or -118- (v) the Master Servicer shall admit in writing its inability to pay its debts generally as they become due, file a petition to take advantage of any applicable insolvency or reorganization statute, make an assignment for the benefit of its creditors, or voluntarily suspend payment of its obligations; or (vi) any failure by the Master Servicer of the Delinquency Master Servicer Termination Trigger; or (vii) any failure of the Master Servicer to make any Advance on any Master Servicer Remittance Date required to be made from its own funds pursuant to Section 4.03 which continues unremedied until 5:00 p.m. New York time on such Master Servicer Remittance Date. If a Master Servicer Event of Default described in clauses (i) through (vi) of this Section shall occur, then, and in each and every such case, so long as such Master Servicer Event of Default shall not have been remedied, the Depositor or the Trustee may, and at the written direction of the Holders of Certificates entitled to at least 51% of Voting Rights or the NIMS Insurer, the Trustee shall, by notice in writing to the Master Servicer (and to the Depositor if given by the Trustee or to the Trustee if given by the Depositor), terminate all of the rights and obligations of the Master Servicer in its capacity as Master Servicer under this Agreement, to the extent permitted by law, and in and to the Mortgage Loans and the proceeds thereof. If a Master Servicer Event of Default described in clause (vii) hereof shall occur, the Trustee shall, by notice in writing to the Master Servicer, the Depositor and the NIMS Insurer, terminate all of the rights and obligations of the Master Servicer in its capacity as Master Servicer under this Agreement and in and to the Mortgage Loans and the proceeds thereof. On or after the receipt by the Master Servicer of such written notice, all authority and power of the Master Servicer under this Agreement, whether with respect to the Certificates (other than as a Holder of any Certificate) or the Mortgage Loans or otherwise, shall pass to and be vested in the Trustee pursuant to and under this Section, and, without limitation, the Trustee is hereby authorized and empowered, as attorney-in-fact or otherwise, to execute and deliver, on behalf of and at the expense of the Master Servicer, any and all documents and other instruments and to do or accomplish all other acts or things necessary or appropriate to effect the purposes of such notice of termination, whether to complete the transfer and endorsement or assignment of the Mortgage Loans and related documents, or otherwise. The Master Servicer agrees to promptly (and in any event no later than ten Business Days subsequent to such notice) provide the Trustee with all documents and records requested by it to enable it to assume the Master Servicer's functions under this Agreement, and to cooperate with the Trustee in effecting the termination of the Master Servicer's responsibilities and rights under this Agreement, including, without limitation, the transfer within one Business Day to the Trustee for administration by it of all cash amounts which at the time shall be or should have been credited by the Master Servicer to the Collection Account held by or on behalf of the Master Servicer, the Distribution Account or any REO Account or Servicing Account held by or on behalf of the Master Servicer or thereafter be received with respect to the Mortgage Loans or any REO Property serviced by the Master Servicer (provided, however, that the Master Servicer shall continue to be entitled to receive all amounts accrued or owing to it under this Agreement on or prior to the date of such termination, whether in respect of Advances or otherwise, and shall continue to be entitled to the benefits of Section 6.03, notwithstanding any such termination, with respect to events occurring prior to such termination). -119- For purposes of this Section 7.01, the Trustee shall not be deemed to have knowledge of a Master Servicer Event of Default unless a Responsible Officer of the Trustee assigned to and working in the Trustee's Corporate Trust Office has actual knowledge thereof or unless written notice of any event which is in fact such a Master Servicer Event of Default is received by the Trustee and such notice references the Certificates, the Trust Fund or this Agreement. SECTION 7.02. Trustee to Act; Appointment of Successor. (a)(1) Within 90 days of the time the Master Servicer (and the Trustee, if notice is sent by the Holders of Certificates entitled to at least 51% of Voting Rights or the NIMS Insurer) receives a notice of termination, the Trustee (or such other successor Master Servicer as is acceptable to the NIMS Insurer) shall be the successor in all respects to the Master Servicer in its capacity as Master Servicer under this Agreement and the transactions set forth or provided for herein, and all the responsibilities, duties and liabilities relating thereto and arising thereafter shall be assumed by the Trustee (except for any representations or warranties of the Master Servicer under this Agreement, the responsibilities, duties and liabilities contained in Section 2.05 (other than with respect to Section 2.05(x)) and the obligation to deposit amounts in respect of losses pursuant to Section 3.12) by the terms and provisions hereof; provided, however, the Trustee shall immediately assume the Master Servicer's obligations to make Advances pursuant to Section 4.03; provided, further, however, that if the Trustee is prohibited by law or regulation from obligating itself to make advances regarding delinquent mortgage loans, then the Trustee shall not be obligated to make Advances pursuant to Section 4.03; and provided further, that any failure to perform such duties or responsibilities caused by the Master Servicer's failure to provide information required by Section 7.01 shall not be considered a default by the Trustee as successor to the Master Servicer hereunder. It is understood and acknowledged by the parties hereto that there will be a period of transition (not to exceed 90 days) before the transition of servicing obligations is fully effective. As compensation therefor, the Trustee shall be entitled to the Servicing Fee and all funds relating to the Mortgage Loans to which the Master Servicer would have been entitled if it had continued to act hereunder. Notwithstanding the above and subject to Section 7.02(a)(2) below, the Trustee if it shall be unwilling to so act, or shall, if it is unable to so act or if it is prohibited by law from making advances regarding delinquent mortgage loans or if the Holders of Certificates entitled to at least 51% of the Voting Rights or the NIMS Insurer so request in writing to the Trustee, promptly appoint or petition a court of competent jurisdiction to appoint, an established mortgage loan servicing institution acceptable to each Rating Agency and the NIMS Insurer and having a net worth of not less than $15,000,000, as the successor to the Master Servicer under this Agreement in the assumption of all or any part of the responsibilities, duties or liabilities of the Master Servicer under this Agreement. Pending appointment of a successor to the Master Servicer hereunder, unless the Trustee is prohibited by law from so acting, the Trustee shall act in such capacity as hereinabove provided. In connection with such appointment and assumption, the successor shall be entitled to receive compensation out of payments on Mortgage Loans in an amount equal to the compensation which the Master Servicer would otherwise have received pursuant to Section 3.18 (or such other compensation as the Trustee and such successor shall agree, not to exceed the Servicing Fee). The appointment of a successor Master Servicer shall not affect any liability of the predecessor Master Servicer which may have arisen under this Agreement prior to its termination as Master Servicer to -120- pay any deductible under an insurance policy pursuant to Section 3.14 or to indemnify the NIMS Insurer pursuant to Section 6.03), nor shall any successor Master Servicer be liable for any acts or omissions of the predecessor Master Servicer or for any breach by such Master Servicer of any of its representations or warranties contained herein or in any related document or agreement. The Trustee and such successor shall take such action, consistent with this Agreement, as shall be necessary to effectuate any such succession. All Servicing Transfer Costs shall be paid by the predecessor Master Servicer upon presentation of reasonable documentation of such costs, and if such predecessor Master Servicer defaults in its obligation to pay such costs, such costs shall be paid by the successor Master Servicer or the Trustee (in which case the successor Master Servicer or the Trustee, as applicable, shall be entitled to reimbursement therefor from the assets of the Trust Fund pursuant to Section 3.11(b)). (2) No appointment of a successor to the Master Servicer under this Agreement shall be effective until the assumption by the successor of all of the Master Servicer's responsibilities, duties and liabilities hereunder. In connection with such appointment and assumption described herein, the Trustee may make such arrangements for the compensation of such successor out of payments on Mortgage Loans as it and such successor shall agree; provided, however, that no such compensation shall be in excess of that permitted the Master Servicer as such hereunder. The Depositor, the Trustee and such successor shall take such action, consistent with this Agreement, as shall be necessary to effectuate any such succession. Pending appointment of a successor to the Master Servicer under this Agreement or the Trustee shall act in such capacity as hereinabove provided. Any successor to the Master Servicer, including the Trustee, shall during the term of its service as servicer continue to service and administer the Mortgage Loans for the benefit of Certificateholders, and maintain in force a policy or policies of insurance covering errors and omissions in the performance of its obligations as Master Servicer hereunder and a Fidelity Bond in respect of its officers, employees and agents to the same extent as the Master Servicer is so required pursuant to Section 3.14. (b) [Reserved] SECTION 7.03. Notification to Certificateholders. (a) Upon any termination of the Master Servicer pursuant to Section 7.01 above or any appointment of a successor to the Master Servicer pursuant to Section 7.02 above, the Trustee shall give prompt written notice thereof to Certificateholders and the NIMS Insurer at their respective addresses appearing in the Certificate Register. (b) Not later than the later of 60 days after the occurrence of any event, which constitutes or which, with notice or lapse of time or both, would constitute a Master Servicer Event of Default or five days after a Responsible Officer of the Trustee becomes aware of the occurrence of such an event, the Trustee shall transmit by mail to the NIMS Insurer and to all Holders of Certificates notice of each such occurrence, unless such default or Master Servicer Event of Default shall have been cured or waived. -121- SECTION 7.04. Waiver of Master Servicer Events of Default. The Holders representing at least 66% of the Voting Rights (with the consent of the NIMS Insurer) evidenced by all Classes of Certificates affected by any default or Master Servicer Event of Default hereunder may waive such default or Master Servicer Event of Default; provided, however, that a default or Master Servicer Event of Default under clause (i) or (vii) of Section 7.01 may be waived only by all of the Holders of the Regular Certificates (with the consent of the NIMS Insurer). Upon any such waiver of a default or Master Servicer Event of Default, such default or Master Servicer Event of Default shall cease to exist and shall be deemed to have been remedied for every purpose hereunder. No such waiver shall extend to any subsequent or other default or Master Servicer Event of Default or impair any right consequent thereon except to the extent expressly so waived. Notice of any such waiver shall be given by the Trustee to the Rating Agencies and the NIMS Insurer. SECTION 7.05. Survivability of Master Servicer Liabilities. Notwithstanding anything herein to the contrary, upon termination of the Master Servicer hereunder, any liabilities of the Master Servicer which accrued prior to such termination shall survive such termination. -122- ARTICLE VIII CONCERNING THE TRUSTEE SECTION 8.01. Duties of Trustee The Trustee prior to the occurrence of a Master Servicer Event of Default and after the curing of all Master Servicer Events of Default which may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Agreement. During a Master Servicer Event of Default, the Trustee shall exercise such of the rights and powers vested in it by this Agreement, and use the same degree of care and skill in their exercise as a prudent person would exercise or use under the circumstances in the conduct of such person's own affairs. Any permissive right of the Trustee enumerated in this Agreement shall not be construed as a duty. The Trustee upon receipt of all resolutions, certificates, statements, opinions, reports, documents, orders or other instruments furnished to it, which are specifically required to be furnished pursuant to any provision of this Agreement, shall examine them to determine whether they conform to the requirements of this Agreement. If any such instrument is found not to conform to the requirements of this Agreement in a material manner, it shall take such action as it deems appropriate to have the instrument corrected, and if the instrument is not corrected to its satisfaction, it will provide notice thereof to the Certificateholders and the NIMS Insurer. 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 misconduct; provided, however, that: (i) Prior to the occurrence of a Master Servicer Event of Default, and after the curing of all such Master Servicer 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 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 that conform to the requirements of this Agreement; (ii) The Trustee shall not be personally liable for an error of judgment made in good faith by a Responsible Officer or Responsible Officers of it unless it shall be proved that it was negligent in ascertaining the pertinent facts; and (iii) The Trustee shall not be personally liable with respect to any action taken, suffered or omitted to be taken by it in good faith in accordance with the direction of the NIMS Insurer or the Holders of Certificates entitled to at least 25% of the Voting Rights relating to the time, method and place of conducting any proceeding for any remedy available to it or exercising any trust or power conferred upon it under this Agreement. -123- SECTION 8.02. Certain Matters Affecting the Trustee (a) Except as otherwise provided in Section 8.01: (i) The Trustee may request and 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 reasonably believed by it to be genuine and to have been signed or presented by the proper party or parties; (ii) The Trustee may consult with counsel and any 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 Opinion of Counsel; (iii) The Trustee shall not be under any 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 or the NIMS Insurer, pursuant to the provisions of this Agreement, unless such Certificateholders or the NIMS Insurer, as applicable, shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities which may be incurred therein or thereby; nothing contained herein shall, however, relieve the Trustee of the obligation, upon the occurrence of a Master Servicer Event of Default (which has not been cured or waived), to exercise such of the rights and powers vested in it by this Agreement, and to use the same degree of care and skill in their exercise as a prudent person would exercise or use under the circumstances in the conduct of such person's own affairs; (iv) The Trustee shall not be personally liable for any action taken, suffered or omitted by it in good faith and believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Agreement; (v) Prior to the occurrence of a Master Servicer Event of Default hereunder and after the curing of all Master Servicer 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 the NIMS Insurer or the Holders of Certificates entitled to at least 25% of the Voting Rights; 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 such Certificateholders, the Trustee may require reasonable indemnity against such expense, or liability from such Certificateholders or the NIMS Insurer, as applicable, as a condition to taking any such action; (vi) The Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys; and -124- (vii) The Trustee shall not be personally liable for any loss resulting from the investment of funds held in the Collection Account at the direction of the Master Servicer pursuant to Section 3.12. (b) All rights of action under this Agreement or under any of the Certificates, enforceable by the Trustee, may be enforced by it without the possession of any of the Certificates, or the production thereof at the trial or other proceeding relating thereto, and any such suit, action or proceeding instituted by the Trustee shall be brought in its name for the benefit of all the Holders of such Certificates, subject to the provisions of this Agreement. (c) The Trustee is hereby directed by the Depositor to execute and deliver the Cap Contract on behalf of the Trust Fund in the form presented to it by the Depositor. SECTION 8.03. Trustee not Liable for Certificates or Mortgage Loans. The recitals contained herein and in the Certificates (other than the signature of the Trustee, the authentication of the Trustee on the Certificates, the acknowledgments of the Trustee contained in Article II and the representations and warranties of the Trustee in Section 8.12) shall be taken as the statements of the Depositor and the Trustee shall not assume any responsibility for their correctness. The Trustee shall not make any representations or warranties as to the validity or sufficiency of this Agreement (other than as specifically set forth in Section 8.12) or of the Certificates (other than the signature of the Trustee, and authentication of the Trustee on the Certificates) or of any Mortgage Loan or related document. The Trustee shall not be accountable for the use or application by the Depositor of any of the Certificates or of the proceeds of such Certificates, or for the use or application of any funds paid to the Depositor or the Master Servicer in respect of the Mortgage Loans or deposited in or withdrawn from the Collection Account by the Master Servicer, other than any funds held by or on behalf of the Trustee in accordance with Section 3.10. SECTION 8.04. Trustee May Own Certificates. The Trustee in its individual capacity or any other capacity may become the owner or pledgee of Certificates with the same rights it would have if it were not the Trustee. SECTION 8.05. Trustee's Fees and Expenses. The Trustee shall be entitled to withdraw from the Distribution Account, pursuant to Section 3.11(b), on each Distribution Date and pay to itself the Trustee Fee. The Trustee and any director, officer, employee or agent of the Trustee, shall be indemnified by the Trust Fund and held harmless against any loss, liability or expense (not including expenses, disbursements and advances incurred or made by the Trustee including the compensation and the expenses and disbursements of its agents and counsel, in the ordinary course of the Trustee's performance in accordance with the provisions of this Agreement) incurred by the Trustee arising out of or in connection with the acceptance or administration of its obligations and duties under this Agreement, other than any loss, liability or expense (i) resulting from any breach of the Master Servicer's obligations in connection with this Agreement, (ii) that constitutes a specific liability of the Trustee pursuant to Section -125- 10.01(g) or (iii) any loss, liability or expense incurred by reason of willful misfeasance, bad faith or negligence in the performance of duties hereunder or by reason of reckless disregard of obligations and duties hereunder as a result of a breach of the Trustee's obligations under Article X hereof. The Master Servicer agrees to indemnify the Trustee, from, and hold it harmless against, any loss, liability or expense arising in respect of any breach by the Master Servicer of its obligations in connection with this Agreement. Such indemnity shall survive the termination or discharge of this Agreement and the resignation or removal of the Trustee. Any payment hereunder made by the Master Servicer to the Trustee shall be from the Master Servicer's own funds, without reimbursement from REMIC I therefor. SECTION 8.06. Eligibility Requirements for Trustee The Trustee hereunder shall at all times be a corporation or an association (other than the Depositor, the Originator, the Seller, the Master Servicer or any Affiliate of the foregoing) organized and doing business under the laws of any state or the United States of America, authorized under such laws to exercise corporate trust powers, having a combined capital and surplus of at least $50,000,000 (or a member of a bank holding company whose capital and surplus is at least $50,000,000) and subject to supervision or examination by federal or state authority. If such corporation or association publishes reports of conditions 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 or association shall be deemed to be its combined capital and surplus as set forth in its most recent report of conditions 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 8.07. SECTION 8.07. Resignation and Removal of the Trustee The Trustee may at any time resign and be discharged from the trust hereby created by giving written notice thereof to the Depositor, the NIMS Insurer, the Master Servicer and to the Certificateholders. Upon receiving such notice of resignation, the Depositor shall promptly appoint a successor trustee acceptable to the NIMS Insurer by written instrument, in duplicate, which instrument shall be delivered to the resigning Trustee and to the successor trustee. A copy of such instrument shall be delivered to the Certificateholders, the Trustee and the Master Servicer by the Depositor. If no successor trustee shall have been so appointed and have accepted appointment within 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 8.06 and shall fail to resign after written request therefor by the Depositor or the NIMS Insurer, 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 or the NIMS Insurer may remove the and appoint a successor trustee acceptable to the NIMS Insurer by written instrument, in duplicate, which instrument shall be delivered to the Trustee so removed and to the successor trustee. A copy -126- of such instrument shall be delivered to the Certificateholders, the Trustee and the Master Servicer by the Depositor. The Holders of Certificates entitled to at least 51% of the Voting Rights (or the NIMS Insurer upon failure of the Trustee to perform its obligations hereunder) may at any time remove the Trustee and appoint a successor trustee acceptable to the NIMS Insurer 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. A copy of such instrument shall be delivered to the Certificateholders and the Master Servicer by the Depositor. Any resignation or removal of the Trustee and appointment of a successor trustee, pursuant to any of the provisions of this Section shall not become effective until acceptance of appointment by the successor trustee as provided in Section 8.08. Notwithstanding the foregoing, in the event the Trustee is unable to continue to perform its obligations pursuant to the terms of this Agreement prior to the appointment of a successor, the Trustee shall be obligated to perform such obligations until a new trustee is appointed. Such performance shall be without prejudice to any claim by a party hereto or beneficiary hereof resulting from the Trustee's breach of its obligations hereunder. SECTION 8.08. Successor Trustee Any successor trustee appointed as provided in Section 8.07 shall execute, acknowledge and deliver to the Depositor, the NIMS Insurer and 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, 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 to the extent held by it hereunder, as well as all moneys, held by it hereunder, and the Depositor 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 8.06 and the appointment of such successor trustee shall not result in a downgrading of any Class of Certificates by any Rating Agency, as evidenced by a letter from each Rating Agency. Upon acceptance of appointment by a successor trustee, as provided in this Section, the Depositor shall mail notice of the succession of such trustee hereunder to all Holders of Certificates at their addresses as shown in the Certificate Register. If the Depositor fails to mail such notice within 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 8.09. Merger or Consolidation of Trustee. -127- Any corporation or association into which either the Trustee may be merged or converted or with which it may be consolidated or any corporation or association resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation or association succeeding to the business of the Trustee shall be the successor of the Trustee hereunder, provided such corporation or association shall be eligible under the provisions of Section 8.06, 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 8.10. Appointment of Co-Trustee or Separate Trustee. Notwithstanding any other provisions hereof, at any time, for the purpose of meeting any legal requirements of any jurisdiction in which any part of REMIC I or property securing the same may at the time be located, the Trustee shall have the power and shall execute and deliver all instruments to appoint one or more Persons approved by the Trustee and the NIMS Insurer to act as co-trustee or co-trustees, jointly with the Trustee, or separate trustee or separate trustees, of all or any part of REMIC I, and to vest in such Person or Persons, in such capacity, such title to REMIC I, or any part thereof, and, subject to the other provisions of this Section 8.10, such powers, duties, obligations, rights and trusts as the Trustee may consider necessary or desirable. Any such co-trustee or separate trustee shall be subject to the written approval of the NIMS Insurer. If the NIMS Insurer shall not have joined in such appointment within 15 days after the receipt by it of a request to do so, 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 8.06 hereunder and no notice to Holders of Certificates of the appointment of co-trustee(s) or separate trustee(s) shall be required under Section 8.08 hereof. In the case of any appointment of a co-trustee or separate trustee pursuant to this Section 8.10 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, except to the extent that under any law of any jurisdiction in which any particular act or acts are to be performed by the Trustee (whether as Trustee hereunder or as successor to a defaulting Master Servicer hereunder), the Trustee shall be incompetent or unqualified to perform such act or acts, in which event such rights, powers, duties and obligations (including the holding of title to REMIC I 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. Any notice, request or other writing given to the Trustee shall be deemed to have been given to each of the then separate trustees and co-trustees, as effectively as if given to each of them. Every instrument appointing any separate trustee or co-trustee shall refer to this Agreement and the conditions of this Article VIII. Each separate trustee and co-trustee, upon its acceptance of the trust conferred, shall be vested with the estates or property specified in its instrument of appointment, either jointly with the Trustee, or separately, as may be provided therein, subject to all the provisions of this Agreement, specifically including every provision of this Agreement relating to the conduct of, affecting the liability of, or affording protection to, the Trustee. Every such instrument shall be filed with the Trustee and a copy thereof given to the NIMS Insurer. -128- Any separate trustee or co-trustee may, at any time, constitute the Trustee, its agent or attorney-in-fact, with full power and authority, to the extent not prohibited by law, to do any lawful act under or in respect of this Agreement on its behalf and in its name. If any separate trustee or co-trustee shall die, become incapable of acting, resign or be removed, all of its estates, properties, rights, remedies and trusts shall vest in and be exercised by the Trustee, to the extent permitted by law, without the appointment of a new or successor trustee or co-trustee. SECTION 8.11. Appointment of Office or Agency. The Trustee will appoint an office or agency in the City of Minneapolis, Minnesota where the Certificates may be surrendered for registration of transfer or exchange, and presented for final distribution, and where notices and demands to or upon the Trustee in respect of the Certificates and this Agreement may be served.

The Trustee hereby represents and warrants to the Master Servicer and the Depositor, as of the Closing Date, that: (i) It is a national banking association duly organized, validly existing and in good standing under the laws of the United States of America. (ii) The execution and delivery of this Agreement by it, and the performance and compliance with the terms of this Agreement by it, will not violate its articles of association or bylaws 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 agreement or other instrument to which it is a party or which is applicable to it or any of its assets. (iii) It has the full power and authority to enter into and consummate all transactions contemplated by this Agreement, has duly authorized the execution, delivery and performance of this Agreement, and has duly executed and delivered this Agreement. (iv) This Agreement, assuming due authorization, execution and delivery by the other parties hereto, constitutes a valid, legal and binding obligation of it, enforceable against it in accordance with the terms hereof, subject to (A) applicable bankruptcy, insolvency, receivership, reorganization, moratorium and other laws affecting the enforcement of creditors'rights generally, and (B) general principles of equity, regardless of whether such enforcement is considered in a proceeding in equity or at law. (v) It is not in violation of, and its execution and delivery of this Agreement and its performance and compliance with the terms of this Agreement will not constitute a violation of, any law, any order or decree of any court or arbiter, or any order, regulation or demand of any federal, state or local governmental or regulatory authority, which violation, in its good faith and reasonable judgment, is likely to affect materially and adversely either the ability of it to perform its obligations under this Agreement or its financial condition. -129- (vi) No litigation is pending or, to the best of its knowledge, threatened against it, which would prohibit it from entering into this Agreement or, in its good faith reasonable judgment, is likely to materially and adversely affect either the ability of it to perform its obligations under this Agreement or its financial condition. -130- ARTICLE IX TERMINATION SECTION 9.01. Termination Upon Repurchase or Liquidation of All Mortgage Loans. (a) Subject to Section 9.02, the respective obligations and responsibilities under this Agreement of the Depositor, the Master Servicer and the Trustee (other than the obligations of the Master Servicer to the Trustee pursuant to Section 8.05 and of the Master Servicer to make remittances to the Trustee and the Trustee to make payments in respect of the REMIC I Regular Interests and the Classes of Certificates as hereinafter set forth) shall terminate upon payment to the Certificateholders and the deposit of all amounts held by or on behalf of the Trustee and required hereunder to be so paid or deposited on the Distribution Date coinciding with or following the earlier to occur of (i) the purchase by the Terminator (as defined below) of all Mortgage Loans and each REO Property remaining in REMIC I and (ii) the final payment or other liquidation (or any advance with respect thereto) of the last Mortgage Loan or REO Property remaining in REMIC I; 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, living on the date hereof. Subject to Section 3.10 hereof, the purchase by the Terminator of all Mortgage Loans and each REO Property remaining in REMIC I shall be at a price (the "Termination Price") equal to the aggregate fair market value of all of the assets of REMIC I (as determined by the Terminator and the Trustee, as of the close of business on the third Business Day next preceding the date upon which notice of any such termination is furnished to Certificateholders pursuant to the third paragraph of this Section 9.01) plus accrued and unpaid interest thereon at the weighted average of the Mortgage Rates through the end of the Due Period preceding the final Distribution Date plus unreimbursed Servicing Advances, Advances, any unpaid Servicing Fees allocable to such Mortgage Loans and REO Properties, any accrued and unpaid Net WAC Rate Carryover Amount (the "Termination Price"); provided, however, such option may only be exercised if (i) the Termination Price is sufficient to pay all interest accrued on, as well as amounts necessary to retire the principal balance of, each class of notes issued pursuant to the Indenture and any remaining amounts owed to the NIMS Insurer on the date such option is exercised and (ii) the fair market value of the Mortgage Loans and REO Properties described above is at least equal to the Principal Balance of the Mortgage Loans (after giving effect to scheduled payments of principal due during the related Due Period, to the extent received or advanced, and unscheduled collections of principal received during the related Prepayment Period) and the appraised value of the REO Properties. (b) The majority holder of the Class CE Certificates (so long as such holder is not an affiliate of the Seller) or if such majority holder fails to exercise such right, the Master Servicer (or if the Master Servicer fails to exercise such right, the NIMS Insurer) shall have the right (the party exercising such right, the "Terminator"), to purchase all of the Mortgage Loans and each REO Property remaining in REMIC I pursuant to clause (i) of the preceding paragraph no later than the Determination Date in the month immediately preceding the Distribution Date on which the Certificates will be retired; provided, however, that the Terminator may elect to purchase all of the Mortgage Loans and each REO Property remaining in REMIC I pursuant to clause (i) above only -131- if the aggregate Stated Principal Balance of the Mortgage Loans and each REO Property remaining in the Trust Fund at the time of such election is reduced to less than 10% of the aggregate Stated Principal Balance of the Mortgage Loans as of the Cut-off Date. By acceptance of the Residual Certificates, the Holder of the Residual Certificates agrees, in connection with any termination hereunder, to assign and transfer any amounts in excess of par, and to the extent received in respect of such termination, to pay any such amounts to the Holders of the Class CE Certificates. (c) Notice of the liquidation of the Certificates shall be given promptly by the Trustee by letter to Certificateholders and the NIMS Insurer mailed (a) in the event such notice is given in connection with the purchase of the Mortgage Loans and each REO Property by the Terminator, not earlier than the 10th day and not later than the 20th day of the month next preceding the month of the final distribution on the Certificates or (b) otherwise during the month of such final distribution on or before the Determination Date in such month, in each case specifying (i) the Distribution Date upon which the Trust Fund will terminate and the final payment in respect of the REMIC I Regular Interests and the Certificates will be made upon presentation and surrender of the related Certificates at the office of the Trustee therein designated, (ii) the amount of any such final payment, (iii) that no interest shall accrue in respect of the REMIC I Regular Interests or the Certificates from and after the Accrual Period relating to the final Distribution Date therefor and (iv) that the Record Date otherwise applicable to such Distribution Date is not applicable, payments being made only upon presentation and surrender of the Certificates at the office of the Trustee. In the event such notice is given in connection with the purchase of all of the Mortgage Loans and each REO Property remaining in REMIC I by the Terminator, the Terminator shall deliver to the Trustee for deposit in the Distribution Account not later than the last Business Day of the month next preceding the month of the final distribution on the Certificates an amount in immediately available funds equal to the Termination Price. The Trustee shall remit to the Master Servicer from such funds deposited in the Distribution Account (i) any amounts which the Master Servicer would be permitted to withdraw and retain from the Collection Account pursuant to Section 3.11 and (ii) any other amounts otherwise payable by the Trustee to the Master Servicer from amounts on deposit in the Distribution Account pursuant to the terms of this Agreement, in each case prior to making any final distributions pursuant to Section 10.01(d) below. Upon certification to the Trustee by the Terminator of the making of such final deposit, the Trustee shall promptly release to the Terminator the Mortgage Files for the remaining Mortgage Loans, and the Trustee shall execute all assignments, endorsements and other instruments necessary to effectuate such transfer. (d) Upon presentation of the Certificates by the Certificateholders on the final Distribution Date, the Trustee shall distribute to each Certificateholder so presenting and surrendering its Certificates the amount otherwise distributable on such Distribution Date in accordance with Section 4.01 in respect of the Certificates so presented and surrendered. Any funds not distributed to any Holder or Holders of Certificates being retired on such Distribution Date because of the failure of such Holder or Holders to tender their Certificates shall, on such date, be set aside and held in trust and credited to the account of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given pursuant to this Section 9.01 shall not have been surrendered for cancellation within six months after the time specified in such notice, the Trustee shall mail a second notice to the remaining non-tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for -132- cancellation, the Trustee shall, directly or through an agent, mail a final notice to the remaining non-tendering Certificateholders concerning surrender of their Certificates. The costs and expenses of maintaining the funds in trust and of contacting such Certificateholders shall be paid out of the assets remaining in the Trust Fund. If within one year after the final notice any such Certificates shall not have been surrendered for cancellation, the Trustee shall pay to UBS Warburg LLC all such amounts, and all rights of non-tendering Certificateholders in or to such amounts shall thereupon cease. No interest shall accrue or be payable to any Certificateholder on any amount held in trust by the Trustee as a result of such Certificateholder's failure to surrender its Certificate(s) for final payment thereof in accordance with this Section 9.01. Any such amounts held in trust by the Trustee shall be held in an Eligible Account and the Trustee may direct any depository institution maintaining such account to invest the funds in one or more Permitted Investments. All income and gain realized from the investment of funds deposited in such accounts held in trust by the Trustee shall be for the benefit of the Trustee; provided, however, that the Trustee shall deposit in such account the amount of any loss of principal incurred in respect of any such Permitted Investment made with funds in such accounts immediately upon the realization of such loss. Immediately following the deposit of funds in trust hereunder in respect of the Certificates, the Trust Fund shall terminate. SECTION 9.02. Additional Termination Requirements. (a) In the event that the Terminator purchases all the Mortgage Loans and each REO Property or the final payment on or other liquidation of the last Mortgage Loan or REO Property remaining in REMIC I pursuant to Section 9.01, the Trust Fund shall be terminated in accordance with the following additional requirements: (i) The Trustee shall specify the first day in the 90-day liquidation period in a statement attached to each Trust REMIC's final Tax Return pursuant to Treasury regulation Section 1.860F-1 and shall satisfy all requirements of a qualified liquidation under Section 860F of the Code and any regulations thereunder, as evidenced by an Opinion of Counsel obtained at the expense of the Terminator; (ii) During such 90-day liquidation period and, at or prior to the time of making of the final payment on the Certificates, the Trustee shall sell all of the assets of REMIC I to the Terminator for cash; and (iii) At the time of the making of the final payment on the Certificates, the Trustee shall distribute or credit, or cause to be distributed or credited, to the Holders of the Residual Certificates all cash on hand in the Trust Fund (other than cash retained to meet claims), and the Trust Fund shall terminate at that time. (b) At the expense of the requesting Terminator, the Depositor shall prepare or cause to be prepared the documentation required in connection with the adoption of a plan of liquidation of each Trust REMIC pursuant to this Section 9.02. -133- (c) By their acceptance of Certificates, the Holders thereof hereby agree to authorize the Trustee to specify the 90-day liquidation period for each Trust REMIC, which authorization shall be binding upon all successor Certificateholders. -134- ARTICLE X REMIC PROVISIONS SECTION 10.01. REMIC Administration. (a) The Trustee shall elect to treat each Trust REMIC as a REMIC under the Code and, if necessary, under applicable state law. Each such election will be made by the Trustee on Form 1066 or other appropriate federal tax or information return or any appropriate state return for the taxable year ending on the last day of the calendar year in which the Certificates are issued. For the purposes of the REMIC election in respect of REMIC I, the REMIC I Regular Interests shall be designated as the Regular Interests in REMIC I and the Class R-I Interest shall be designated as the Residual Interest in REMIC I. The Class A Certificates, the Mezzanine Certificates, the Class CE Certificates and the Class P Certificates shall be designated as the Regular Interests in REMIC II and the Class R-II Interest shall be designated as the Residual Interest in REMIC II. The Trustee shall not permit the creation of any "interests" in any Trust REMIC (within the meaning of Section 860G of the Code) other than the REMIC I Regular Interests and the interests represented by the Certificates. (b) The Closing Date is hereby designated as the "Startup Day" of each Trust REMIC within the meaning of Section 860G(a)(9) of the Code. (c) The Trustee shall be reimbursed for any and all expenses relating to any tax audit of the Trust Fund (including, but not limited to, any professional fees or any administrative or judicial proceedings with respect to any Trust REMIC that involve the Internal Revenue Service or state tax authorities), including the expense of obtaining any tax related Opinion of Counsel except as specified herein. The Trustee, as agent for each Trust REMIC's tax matters person shall (i) act on behalf of the Trust Fund in relation to any tax matter or controversy involving any Trust REMIC and (ii) represent the Trust Fund in any administrative or judicial proceeding relating to an examination or audit by any governmental taxing authority with respect thereto. The holder of the largest Percentage Interest of the Residual Certificates shall be designated, in the manner provided under Treasury regulations section 1.860F-4(d) and Treasury regulations section 301.6231(a)(7)-1, as the tax matters person of the related REMIC created hereunder. By their acceptance thereof, the holder of the largest Percentage Interest of the Residual Certificates hereby agrees to irrevocably appoint the Trustee or an Affiliate as its agent to perform all of the duties of the tax matters person for the Trust Fund. (d) The Trustee shall prepare, sign and file all of the Tax Returns (including Form 8811, which must be filed within 30 days following the Closing Date) in respect of each Trust REMIC. The expenses of preparing and filing such returns shall be borne by the Trustee without any right of reimbursement therefor. (e) The Trustee shall perform on behalf of each Trust REMIC all reporting and other tax compliance duties that are the responsibility of such REMIC under the Code, the REMIC Provisions or other compliance guidance issued by the Internal Revenue Service or any state or local taxing authority. Among its other duties, as required by the Code, the REMIC Provisions or other -135- such compliance guidance, the Trustee shall provide (i) to any Transferor of a Residual Certificate such information as is necessary for the application of any tax relating to the transfer of a Residual Certificate to any Person who is not a Permitted Transferee, (ii) to the Certificateholders such information or reports as are required by the Code or the REMIC Provisions including reports relating to interest, original issue discount and market discount or premium (using the Prepayment Assumption as required) and (iii) to the Internal Revenue Service the name, title, address and telephone number of the person who will serve as the representative of each Trust REMIC. The Depositor shall provide or cause to be provided to the Trustee, within ten (10) days after the Closing Date, all information or data that the Trustee reasonably determines to be relevant for tax purposes as to the valuations and issue prices of the Certificates, including, without limitation, the price, yield, prepayment assumption and projected cash flow of the Certificates. (f) The Trustee shall take such action and shall cause each Trust REMIC to take such action as shall be necessary to create or maintain the status thereof as a REMIC under the REMIC Provisions. The Trustee shall not take any action or cause the Trust Fund to take any action or fail to take (or fail to cause to be taken) any action that, under the REMIC Provisions, if taken or not taken, as the case may be, could (i) endanger the status of any Trust REMIC as a REMIC or (ii) result in the imposition of a tax upon the Trust Fund (including but not limited to the tax on prohibited transactions as defined in Section 860F(a)(2) of the Code and the tax on contributions to a REMIC set forth in Section 860G(d) of the Code) (either such event, an "Adverse REMIC Event") unless the Trustee and the NIMS Insurer has received an Opinion of Counsel, addressed to the Trustee (at the expense of the party seeking to take such action but in no event at the expense of the Trustee) to the effect that the contemplated action will not, with respect to any Trust REMIC, endanger such status or result in the imposition of such a tax, nor shall the Master Servicer take or fail to take any action (whether or not authorized hereunder) as to which the Trustee and the NIMS Insurer has advised it in writing that it has received an Opinion of Counsel to the effect that an Adverse REMIC Event could occur with respect to such action; provided that the Master Servicer may conclusively rely on such Opinion of Counsel and shall incur no liability for its action or failure to act in accordance with such Opinion of Counsel. In addition, prior to taking any action with respect to any Trust REMIC or the respective assets of each, or causing any Trust REMIC to take any action, which is not contemplated under the terms of this Agreement, the Master Servicer will consult with the Trustee, the NIMS Insurer or its designee, in writing, with respect to whether such action could cause an Adverse REMIC Event to occur with respect to any Trust REMIC and the Master Servicer shall not take any such action or cause any Trust REMIC to take any such action as to which the Trustee or the NIMS Insurer has advised it in writing that an Adverse REMIC Event could occur; provided that the Master Servicer may conclusively rely on such writing and shall incur no liability for its action or failure to act in accordance with such writing. The Trustee or the NIMS Insurer may consult with counsel to make such written advice, and the cost of same shall be borne by the party seeking to take the action not permitted by this Agreement, but in no event shall such cost be an expense of the Trustee. At all times as may be required by the Code, the Trustee will ensure that substantially all of the assets of REMIC I 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, to the extent such obligations are within the Trustee's control and not otherwise inconsistent with the terms of this Agreement. -136- (g) In the event that any tax is imposed on "prohibited transactions" of any REMIC created hereunder as defined in Section 860F(a)(2) of the Code, on the "net income from foreclosure property" of such REMIC as defined in Section 860G(c) of the Code, on any contributions to any such REMIC after the Startup Day therefor pursuant to Section 860G(d) of the Code, or any other tax is imposed by the Code or any applicable provisions of state or local tax laws, such tax shall be charged (i) to the Trustee pursuant to Section 10.03 hereof, if such tax arises out of or results from a breach by the Trustee of any of its obligations under this Article X, (ii) to the Master Servicer pursuant to Section 10.03 hereof, if such tax arises out of or results from a breach by the Master Servicer of any of its obligations under Article III or this Article X, or (iii) against amounts on deposit in the Distribution Account and shall be paid by withdrawal therefrom. (h) On or before April 15th of each calendar year, commencing April 15, 2003, the Trustee shall deliver to each Rating Agency and the NIMS Insurer an Officer's Certificate of the Trustee stating the Trustee's compliance with this Article X (without regard to any action taken by any party other than the Trustee). (i) The Trustee shall, for federal income tax purposes, maintain books and records with respect to each Trust REMIC on a calendar year and on an accrual basis. (j) Following the Startup Day, neither the Master Servicer nor the Trustee shall accept any contributions of assets to any Trust REMIC other than in connection with any Qualified Substitute Mortgage Loan delivered in accordance with Section 2.03 unless it shall have received an Opinion of Counsel to the effect that the inclusion of such assets in the Trust Fund will not cause the related REMIC to fail to qualify as a REMIC at any time that any Certificates are outstanding or subject such REMIC to any tax under the REMIC Provisions or other applicable provisions of federal, state and local law or ordinances. (k) Neither the Trustee nor the Master Servicer shall enter into any arrangement by which any Trust REMIC will receive a fee or other compensation for services nor permit either REMIC to receive any income from assets other than "qualified mortgages" as defined in Section 860G(a)(3) of the Code or "permitted investments" as defined in Section 860G(a)(5) of the Code. SECTION 10.02. Prohibited Transactions and Activities. None of the Depositor, the Master Servicer or the Trustee shall sell, dispose of or substitute for any of the Mortgage Loans (except in connection with (i) the foreclosure of a Mortgage Loan, including but not limited to, the acquisition or sale of a Mortgaged Property acquired by deed in lieu of foreclosure, (ii) the bankruptcy of REMIC I, (iii) the termination of REMIC I pursuant to Article IX of this Agreement, (iv) a substitution pursuant to Article II of this Agreement or (v) a purchase of Mortgage Loans pursuant to Article II or III of this Agreement), nor acquire any assets for any Trust REMIC (other than REO Property acquired in respect of a defaulted Mortgage Loan), nor sell or dispose of any investments in the Collection Account or the Distribution Account for gain, nor accept any contributions to any Trust REMIC after the Closing Date (other than a Qualified Substitute Mortgage Loan delivered in accordance with Section 2.03), unless it has received an Opinion of Counsel, addressed to the Trustee and the NIMS Insurer (at the expense of the party seeking to cause such sale, disposition, substitution, acquisition or contribution but in no event at -137- the expense of the Trustee) that such sale, disposition, substitution, acquisition or contribution will not (a) affect adversely the status of any Trust REMIC as a REMIC or (b) cause any Trust REMIC to be subject to a tax on "prohibited transactions" or "contributions" pursuant to the REMIC Provisions. SECTION 10.03. Master Servicer and Trustee Indemnification. (a) In the event that any Trust REMIC fails to qualify as a REMIC, loses its status as a REMIC, or incurs federal, state or local taxes as a result of a prohibited transaction or prohibited contribution under the REMIC Provisions due to (i) the negligent performance by the Trustee of its duties and obligations set forth herein or (ii) any state, local or franchise taxes imposed upon the Trust Fund as a result of the location of the Trustee or any co-trustee, the Trustee shall indemnify the NIMS Insurer and the Trust Fund against any and all Losses resulting from such negligence, including, without limitation, any reasonable attorneys' fees imposed on or incurred as a result of a breach of the Trustee's or any co-trustee's covenants; provided, however, that the Trustee shall not be liable for any such Losses attributable to the action or inaction of the Master Servicer, the Depositor or the Holder of such Residual Certificate, as applicable, nor for any such Losses resulting from misinformation provided by the Holder of such Residual Certificate on which the Trustee has relied. The foregoing shall not be deemed to limit or restrict the rights and remedies of the Holder of such Residual Certificate now or hereafter existing at law or in equity. Notwithstanding the foregoing, however, in no event shall the Trustee have any liability (1) for any action or omission that is taken in accordance with and in compliance with the express terms of, or which is expressly permitted by the terms of, this Agreement, (2) for any Losses other than arising out of a negligent performance by the Trustee of its duties and obligations set forth herein, and (3) for any special or consequential damages to Certificateholders (in addition to payment of principal and interest on the Certificates). (b) In the event that any Trust REMIC fails to qualify as a REMIC, loses its status as a REMIC, or incurs federal, state or local taxes as a result of a prohibited transaction or prohibited contribution under the REMIC Provisions due to (i) the negligent performance by the Master Servicer of its duties and obligations set forth herein or (ii) any state, local or franchise taxes imposed upon the Trust Fund as a result of the location of the Master Servicer or any sub-servicer, the Master Servicer shall indemnify the NIMS Insurer, the Trustee and the Trust Fund against any and all losses, claims, damages, liabilities or expenses ("Losses") resulting from such negligence, including, without limitation, any reasonable attorneys' fees imposed on or incurred as a result of a breach of the Master Servicer's or any sub-servicer's covenants; provided, however, that the Master Servicer shall not be liable for any such Losses attributable to the action or inaction of the Trustee, the Depositor or the Holder of such Residual Certificate, as applicable, nor for any such Losses resulting from misinformation provided by the Holder of such Residual Certificate on which the Master Servicer has relied. The foregoing shall not be deemed to limit or restrict the rights and remedies of the Holder of such Residual Certificate now or hereafter existing at law or in equity. Notwithstanding the foregoing, however, in no event shall the Master Servicer have any liability (1) for any action or omission that is taken in accordance with and in compliance with the express terms of, or which is expressly permitted by the terms of, this Agreement, (2) for any Losses other than arising out of a negligent performance by the Master Servicer of its duties and obligations set forth -138- herein, and (3) for any special or consequential damages to Certificateholders (in addition to payment of principal and interest on the Certificates). ARTICLE XI MISCELLANEOUS PROVISIONS SECTION 11.01. Amendment. This Agreement may be amended from time to time by the Depositor, the Master Servicer and the Trustee with the consent of the NIMS Insurer and without the consent of any of the Certificateholders, (i) to cure any ambiguity or defect, (ii) to correct, modify or supplement any provisions herein (including to give effect to the expectations of Certificateholders), or (iii) to make any other provisions with respect to matters or questions arising under this Agreement which shall not be inconsistent with the provisions of this Agreement, provided that such action shall not adversely affect in any material respect the interests of any Certificateholder as evidenced by either (i) an Opinion of Counsel delivered to the Master Servicer, the Trustee and the NIMS Insurer or (ii) confirmation from the Rating Agencies, delivered to the Master Servicer, the Trustee and the NIMS Insurer, that such amendment will not result in the reduction or withdrawal of the rating of any outstanding Class of Certificates. No amendment shall be deemed to adversely affect in any material respect the interests of any Certificateholder who shall have consented thereto, and no Opinion of Counsel shall be required to address the effect of any such amendment on any such consenting Certificateholder. This Agreement may also be amended from time to time by the Depositor, the Master Servicer, the NIMS Insurer and the Trustee with the consent of the NIMS Insurer and the Holders of Certificates entitled to at least 66% of the Voting Rights for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Agreement or of modifying in any manner the rights of the Holders of Certificates; provided, however, that no such amendment shall (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) adversely affect in any material respect the interests of the Holders of any Class of Certificates (as evidenced by either (i) an Opinion of Counsel delivered to the Trustee and the NIMS Insurer or (ii) confirmation from the Rating Agencies, delivered to the Master Servicer, the Trustee and the NIMS Insurer, that such action will not result in the reduction or withdrawal of the rating of any outstanding Class of Certificates) in a manner, other than as described in (i), or (iii) modify the consents required by the immediately preceding clauses (i) and (ii) without the consent of the Holders of all Certificates then outstanding. Notwithstanding any other provision of this Agreement, for purposes of the giving or withholding of consents pursuant to this Section 11.01, Certificates registered in the name of the Depositor or the Master Servicer or any Affiliate thereof shall be entitled to Voting Rights with respect to matters affecting such Certificates. Notwithstanding any contrary provision of this Agreement, neither the Trustee nor the NIMS Insurer shall consent to any amendment to this Agreement unless it shall have first received an Opinion of Counsel satisfactory to the NIMS Insurer to the effect that such amendment will not result in the imposition of any tax on any Trust REMIC pursuant to the REMIC Provisions -139- or cause any Trust REMIC to fail to qualify as a REMIC at any time that any Certificates are outstanding. Promptly after the execution of any such amendment the Trustee shall furnish a copy of such amendment to each Certificateholder and the NIMS Insurer. It shall not be necessary for the consent of Certificateholders under this Section 11.01 to approve the particular form of any proposed amendment, but it shall be sufficient if such consent shall approve the substance thereof. The manner of obtaining such consents and of evidencing the authorization of the execution thereof by Certificateholders shall be subject to such reasonable regulations as the Trustee may prescribe. The cost of any Opinion of Counsel to be delivered pursuant to this Section 11.01 shall be borne by the Person seeking the related amendment, but in no event shall such Opinion of Counsel be an expense of the Trustee. The Trustee may, but shall not be obligated to enter into any amendment pursuant to this Section that affects its rights, duties and immunities under this Agreement or otherwise. SECTION 11.02. Recordation of Agreement; Counterparts. To the extent permitted by applicable law, this Agreement is subject to recordation in all appropriate public offices for real property records in all the counties or other comparable jurisdictions in which any or all of the properties subject to the Mortgages are situated, and in any other appropriate public recording office or elsewhere, such recordation to be effected by the Master Servicer at the expense of the Certificateholders, but only upon direction of the Trustee accompanied by an Opinion of Counsel to the effect that such recordation materially and beneficially affects the interests of the Certificateholders.

Any such consent by the Holder of this Certificate shall be conclusive and binding on such Holder and upon all future Holders of this Certificate and of any Certificate issued upon the transfer hereof or in exchange herefor or in lieu hereof whether or not notation of such consent is made upon this Certificate. The Agreement also permits the amendment thereof, in certain limited circumstances, without the consent of the Holders of any of the Certificates. As provided in the Agreement and subject to certain limitations therein set forth, the transfer of this Certificate is registrable in the Certificate Register upon surrender of this Certificate for registration of transfer at the offices or agencies appointed by the Trustee as provided in the Agreement, duly endorsed by, or accompanied by an assignment in the form below or other written instrument of transfer in form satisfactory to the Trustee duly executed by, the Holder hereof or such Holder's attorney duly authorized in writing, and thereupon one or more new Certificates of the same Class in authorized denominations evidencing the same aggregate Percentage Interest will be issued to the designated transferee or transferees. No transfer of this Certificate shall be made unless the transfer is made pursuant to an effective registration statement under the Securities Act of 1933, as amended (the "1933 Act"), and an effective registration or qualification under applicable state securities laws, or is made in a transaction that does not require such registration or qualification. In the event that such a transfer of this Certificate is to be made without registration or qualification, the Trustee shall require receipt of (i) if such transfer is purportedly being made in reliance upon Rule 144A under the 1933 Act, written certifications from the Holder of the Certificate desiring to effect the transfer, and from such Holder's prospective transferee, substantially in the forms attached to the Agreement as Exhibit F-1, and (ii) in all other cases, an Opinion of Counsel satisfactory to it that such transfer may be made without such registration or qualification (which Opinion of Counsel shall not be an expense of the Trust Fund or of the Depositor, the Trustee or the Master Servicer in their respective capacities as such), together with copies of the written certification(s) of the Holder of the Certificate desiring to effect the transfer and/or such Holder's prospective transferee upon which such Opinion of Counsel is based. Neither the Depositor nor the Trustee is obligated to register or qualify the Class of A-7-4 Certificates specified on the face hereof under the 1933 Act or any other securities law or to take any action not otherwise required under the Agreement to permit the transfer of such Certificates without registration or qualification. Any Holder desiring to effect a transfer of this Certificate shall be required to indemnify the Trustee, the Depositor and the Master Servicer against any liability that may result if the transfer is not so exempt or is not made in accordance with such federal and state laws. No transfer of this Certificate to a Plan subject to ERISA or Section 4975 of the Code, any Person acting, directly or indirectly, on behalf of any such Plan or any Person using "Plan Assets" to acquire this Certificate shall be made except in accordance with Section 5.02(c) of the Agreement. The Certificates are issuable in fully registered form only without coupons in Classes and denominations representing Percentage Interests specified in the Agreement. As provided in the Agreement and subject to certain limitations therein set forth, the Certificates are exchangeable for new Certificates of the same Class in authorized denominations evidencing the same aggregate Percentage Interest, as requested by the Holder surrendering the same. No service charge will be made for any such registration of transfer or exchange of Certificates, but the Trustee may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any transfer or exchange of Certificates. Prior to registration of any transfer, sale or other disposition of this Certificate, the proposed transferee shall provide to the Trustee (i) an affidavit to the effect that such transferee is any Person other than a Disqualified Organization or the agent (including a broker, nominee or middleman) of a Disqualified Organization, and (ii) a certificate that acknowledges that (A) the Class R Certificates have been designated as a residual interest in a REMIC, (B) it will include in its income a PRO RATA share of the net income of the Trust Fund and that such income may be an "excess inclusion," as defined in the Code, that, with certain exceptions, cannot be offset by other losses or benefits from any tax exemption, and (C) it expects to have the financial means to satisfy all of its tax obligations including those relating to holding the Class R Certificates. Notwithstanding the registration in the Certificate Register of any transfer, sale or other disposition of this Certificate to a Disqualified Organization or an agent (including a broker, nominee or middleman) of a Disqualified Organization, such registration shall be deemed to be of no legal force or effect whatsoever and such Person shall not be deemed to be a Certificateholder for any purpose, including, but not limited to, the receipt of distributions in respect of this Certificate. The Holder of this Certificate, by its acceptance hereof, shall be deemed to have consented to the provisions of Section 5.02 of the Agreement and to any amendment of the Agreement deemed necessary by counsel of the Depositor to ensure that the transfer of this Certificate to any Person other than a Permitted Transferee or any other Person will not cause the Trust Fund to cease to qualify as a REMIC or cause the imposition of a tax upon the REMIC. The Depositor, the Master Servicer, the Trustee and any agent of the Depositor, the Master Servicer or the Trustee may treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and none of the Depositor, the Master Servicer, the Trustee nor any such agent shall be affected by notice to the contrary. A-7-5 The obligations created by the Agreement and the Trust Fund created thereby shall terminate upon payment to the Certificateholders of all amounts held by the Trustee and required to be paid to them pursuant to the Agreement following the earlier of (i) the final payment or other liquidation (or any advance with respect thereto) of the last Mortgage Loan and REO Property remaining in REMIC I and (ii) the purchase by the party designated in the Agreement at a price determined as provided in the Agreement from REMIC I of all the Mortgage Loans and all property acquired in respect of such Mortgage Loans. The Agreement permits, but does not require, the party designated in the Agreement to purchase from REMIC I all the Mortgage Loans and all property acquired in respect of any Mortgage Loan at a price determined as provided in the Agreement. The exercise of such right will effect early retirement of the Certificates; however, such right to purchase is subject to the aggregate Stated Principal Balance of the Mortgage Loans at the time of purchase being less than 10% of the aggregate principal balance of the Mortgage Loans as of the Cut-off Date. The recitals contained herein shall be taken as statements of the Depositor and the Trustee assumes no responsibility for their correctness. Unless the certificate of authentication hereon has been executed by the Trustee, by manual signature, this Certificate shall not be entitled to any benefit under the Agreement or be valid for any purpose.

SECTION 6. REPRESENTATIONS AND WARRANTIES OF THE ORIGINATOR RELATING TO THE MORTGAGE LOANS. The Originator hereby represents and warrants to the Purchaser that as to each Mortgage Loan as of the Closing Date: (i) The information set forth in the Mortgage Loan Schedule is complete, true and correct; (ii) [Reserved]; (iii) Except with respect to ____% of the Group I Mortgage Loans and ____% of the Group II Mortgage Loans by outstanding principal balance of each such group, all payments required to be made up to the close of business on the Cut-off Date for such Mortgage Loan under the terms of the Mortgage Note have been made; the Originator has not advanced funds, or induced, solicited or knowingly received any advance of funds from a party other than the owner of the related Mortgaged Property, directly or indirectly, for the payment of any amount required by the Note or Mortgage; and there has been no delinquency, exclusive of any period of grace, in any payment by the Mortgagor thereunder during the last twelve months; (iv) At the time of its sale of the Mortgage Loan, there were no delinquent taxes, ground rents, water charges, sewer rents, assessments, insurance premiums, leasehold payments, including assessments payable in future installments or other outstanding charges affecting the related Mortgaged Property; (v) The terms of the Mortgage Note and the Mortgage have not been impaired, waived, altered or modified in any respect, except by written instruments, recorded in the applicable public recording office if necessary to maintain the lien priority of the Mortgage, and which have been delivered to the Purchaser; the substance of any such waiver, alteration or modification has been approved by the title insurer, to the extent required by the related policy, and is reflected on the Mortgage Loan Schedule. No instrument of waiver, alteration or modification has been executed, and no Mortgagor has been released, in whole or in part, except in connection with an assumption agreement approved by the title insurer, to the extent required by the policy, and which assumption -9- agreement has been delivered to the Purchaser and the terms of which are reflected in the Mortgage Loan Schedule; (vi) The Mortgage Note and the Mortgage are not subject to any right of rescission, set-off, counterclaim or defense, including the defense of usury, nor will the operation of any of the terms of the Mortgage Note and the Mortgage or the exercise of any right thereunder, render the Mortgage unenforceable, in whole or in part, or subject to any right of rescission, set-off, counterclaim or defense, including the defense of usury and no such right of rescission, set-off, counterclaim or defense has been asserted with respect thereto. Except with respect to ____% of the Group I Mortgage Loans and ____% of the Group II Mortgage Loans by outstanding principal balance of each such group, no Mortgagor was a debtor in any state or federal bankruptcy or insolvency proceeding at the time the Mortgage Loan was originated or as of the Closing Date; (vii) All buildings upon the Mortgaged Property are insured by an insurer acceptable to Fannie Mae against loss by fire, hazards of extended coverage and such other hazards as are customary in the area where the Mortgaged Property is located, pursuant to insurance policies conforming to the requirements of the Pooling and Servicing Agreement. All such insurance policies contain a standard mortgagee clause naming the Originator, its successors and assigns as mortgagee and all premiums thereon have been paid. If the Mortgaged Property is in an area identified on a Flood Hazard Map or Flood Insurance Rate Map issued by the Federal Emergency Management Agency as having special flood hazards (and such flood insurance has been made available) a flood insurance policy meeting the requirements of the current guidelines of the Federal Insurance Administration is in effect which policy conforms to the requirements of Fannie Mae and Freddie Mac and is insured by a qualified insurer.

No prior holder of the related Mortgage, including any related seller of the Mortgage Loan, has done, by act or omission, anything which would impair the coverage of such insurance policies; (viii) Any and all requirements of any federal, state or local law including, without limitation, usury, truth in lending, real estate settlement procedures, consumer credit protection; equal credit opportunity, fair housing or disclosure laws applicable to the origination and servicing of loans of a type similar to the Mortgage Loans have been complied with and the Originator shall maintain in its possession available for inspection, and shall deliver to the Purchaser, upon reasonable request, evidence of compliance with all such requirements; (ix) The Mortgage has not been satisfied, cancelled, subordinated or rescinded, in whole or in part, and the Mortgaged Property has not been released from the lien of the Mortgage, in whole or in part, nor has any instrument been executed that would effect any such satisfaction, cancellation, subordination, rescission or release; (x) The Mortgage is a valid, existing, enforceable and perfected first or second lien on the Mortgaged Property, including all improvements on the Mortgaged Property subject only to (a) the lien of current real property taxes and assessments not yet due and payable, (b) covenants, conditions and restrictions, rights of way, easements and other matters of the public record as of the -10- date of recording being acceptable to mortgage lending institutions generally and specifically referred to in the lender's title insurance policy delivered to the Originator and which do not adversely affect the Value of the Mortgaged Property, (c) 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 and (d) in the case of any second lien Mortgage Loan, the first lien on 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, existing and enforceable first or second lien and first or second priority security interest on the property described therein and the Originator and any related seller of the Mortgage Loan had full right to sell and assign the same to the Seller. The Mortgaged Property was not, as of the date of origination of the Mortgage Loan, subject to a mortgage, deed of trust, deed to secure debt or other security instrument creating a lien subordinate to the lien of the Mortgage; (xi) The Mortgage Note and the related Mortgage are genuine and each is the legal, valid and binding obligation of the maker thereof, enforceable in accordance with its terms; (xii) All parties to the Note and the Mortgage had legal capacity to enter into the Mortgage Loan and to execute and deliver the Mortgage Note and the Mortgage, and the Mortgage Note and the Mortgage have been duly and properly executed by such parties.

All costs, fees and expenses incurred in making or closing the Loan and the recording of the Mortgage have been paid, and the Mortgagor is not entitled to any refund of any amounts paid or due to the Mortgagee pursuant to the Mortgage Note or Mortgage; (xiv) At the time of its sale of the Mortgage Loan, the Originator was the sole legal, beneficial and equitable owner of the Mortgage Note and the Mortgage and had full right to transfer and sell the Mortgage Loan free and clear of any encumbrance, equity, lien, pledge, charge, claim or security interest; (xv) All parties which had any interest in the Mortgage Loan, whether as mortgagee, assignee or otherwise, are (or, during the period in which they held and disposed of such interest, were) in compliance with any and all applicable "doing business" and licensing requirements of the laws of the state wherein the Mortgaged Property is located; (xvi) The Mortgage Loan is covered by an ALTA lender's title insurance policy (which, in the case of an Adjustable-Rate Mortgage Loan has an adjustable rate mortgage endorsement in the form of ALTA 6.0 or 6.1) or with respect to any Mortgage Loan for which the related Mortgaged Property is located in California a CLTA lender's title insurance policy, or other generally acceptable form of policy or insurance acceptable to Fannie Mae and Freddie Mac, issued by a title insurer acceptable to Fannie Mae and Freddie Mac and qualified to do business in the -11- jurisdiction where the Mortgaged Property is located, insuring (subject to the exceptions contained in (x)(a) and (b) above) the Originator, its successors and assigns as to the first or second priority lien of the Mortgage in the original principal amount of the Mortgage Loan and, with respect to any Adjustable-Rate Mortgage Loan, against any loss by reason of the invalidity or unenforceability of the lien resulting from the provisions of the Mortgage providing for adjustment in the Mortgage Rate and Monthly Payment. Additionally, such lender's title insurance policy affirmatively insures ingress and egress to and from the Mortgaged Property, and against encroachments by or upon the Mortgaged Property or any interest therein. The Originator is the sole insured 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 Originator, has done, by act or omission, anything which would impair the coverage of such lender's title insurance policy; (xvii) There is no default, breach, violation or event of acceleration existing under the Mortgage Note or the Mortgage 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 of acceleration, and neither the Originator nor any related seller of the Mortgage Loan, has waived any default, breach, violation or event of acceleration; (xviii) There are no mechanics' or similar liens or claims which have been filed for work, labor or material (and no rights are outstanding that under law could give rise to such lien) affecting the related Mortgaged Property which are or may be liens prior to, or equal or coordinate with, the lien of the related Mortgage; (xix) All improvements which were considered in determining the Value of the related Mortgaged Property lay wholly within the boundaries and building restriction lines of the Mortgaged Property, and no improvements on adjoining properties encroach upon the Mortgaged Property unless otherwise disclosed and are affirmatively insured by the title insurance policy referred to in (xvi) above; (xx) The Mortgage Loan was originated by the Originator or by a savings and loan association, a savings bank, a commercial bank or similar banking institution which is supervised and examined by a federal or state authority, or by a mortgagee approved as such by the Secretary of HUD; (xxi) Principal payments on the Mortgage Loan shall commence (with respect to any newly originated Mortgage Loans) or commenced no more than two months after the proceeds of the Mortgage Loan were disbursed. The Mortgage Loan bears interest at the Mortgage Rate.

The Mortgage Note does not permit negative amortization; (xxii) The Mortgaged Property is free of material damage and waste and there is no proceeding pending, or to the best of the Originator's or any related seller's knowledge threatened, for the total or partial condemnation thereof; (xxiii) The Mortgage and related Mortgage Note contain 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, (a) in the case of a Mortgage designated as a deed of trust, by trustee's sale, and (b) otherwise by judicial foreclosure. Upon default by a Mortgagor on a Mortgage Loan and foreclosure on, or trustee's sale of, the Mortgaged Property pursuant to the proper procedures, the holder of the Mortgage Loan will be able to deliver good and merchantable title to the Mortgaged Property. The Mortgaged Property has not been subject to any bankruptcy proceeding or foreclosure proceeding and the Mortgagor has not filed for protection under applicable bankruptcy laws. 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.

All rights and remedies of the Purchaser under this Agreement are distinct from, and cumulative with, any other rights or remedies under this Agreement or afforded by law or equity and all such rights and remedies may be exercised concurrently, independently or successively. Notwithstanding the foregoing, if on the Closing Date, each of the conditions set forth in Section 8 hereof shall have been satisfied and the Purchaser shall not have paid or caused to be paid the Purchase Price, or any such condition shall not have been waived or satisfied and the -20- Purchaser determines not to pay or cause to be paid the Purchase Price, the Purchaser shall immediately effect the re-delivery of the Mortgage Loans, if delivery to the Purchaser has occurred, and the security interest created by this Section 12 shall be deemed to have been released. SECTION 14. NOTICES. All demands, notices and communications hereunder shall be in writing and shall be deemed to have been duly given if personally delivered to or mailed by registered mail, postage prepaid, or transmitted by fax and, receipt of which is confirmed by telephone, if to the Purchaser, addressed to the Purchaser at 1285 Avenue of the Americas, New York, New York 10019, facsimile number (212) 713-7999, Attention: Glenn McIntyre, or such other address as may hereafter be furnished to the Seller and the Originator in writing by the Purchaser; if to the Seller, addressed to the Seller at 1285 Avenue of the Americas, New York, New York 10019, facsimile number (212) 713-7999, Attention: Glenn McIntyre, or to such other address as the Seller may designate in writing to the Purchaser and the Originator; and if to the Originator, addressed to Option One Mortgage Corporation at 3 Ada, Irvine, California 92612, fax (949) 790- 7540, Attention: William O'Neill, or such other address as may hereafter be furnished to the Seller and the Purchaser in writing by the Originator.

Any part, provision, representation or warranty of this Agreement that is prohibited or unenforceable or is held to be void or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction as to any Mortgage Loan shall not invalidate or render unenforceable such provision in any other jurisdiction. To the extent permitted by applicable law, the parties hereto waive any provision of law which prohibits or renders void or unenforceable any provision hereof. SECTION 16. AGREEMENT OF PARTIES. The Originator, the Seller and the Purchaser each agree to execute and deliver such instruments and take such actions as either of the others may, from time to time, reasonably request in order to effectuate the purpose and to carry out the terms of this Agreement and the Pooling and Servicing Agreement. SECTION 17. SURVIVAL. (a) The Seller agrees that the representations, warranties and agreements made by it herein and in any certificate or other instrument delivered pursuant hereto shall be deemed to be relied upon by the Purchaser, notwithstanding any investigation heretofore or hereafter made by the Purchaser or on its behalf, and that the representations, warranties and agreements made by the Seller herein or in any such certificate or other instrument shall survive the delivery of and payment for the Mortgage Loans and shall continue in full force and effect, notwithstanding any restrictive or qualified endorsement on the Mortgage Notes and notwithstanding subsequent termination of this Agreement, the Pooling and Servicing Agreement or the Trust Fund. (b) the Originator agrees that the representations, warranties and agreements made by it herein and in any certificate or other instrument delivered pursuant hereto shall be deemed to be relied upon by the Seller and the Purchaser notwithstanding any investigation heretofore or hereafter made by the Seller or the Purchaser or on the behalf of either of them, and that the representations, warranties and agreements made by the Originator herein or in any such certificate shall continue in full force and -21- effect, notwithstanding subsequent termination of this Agreement, the Pooling and Servicing Agreement or the Trust Fund.

THIS AGREEMENT AND THE RIGHTS, DUTIES, OBLIGATIONS AND RESPONSIBILITIES OF THE PARTIES HERETO SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS (OTHER THAN THE CHOICE OF LAW PROVISIONS THEREIN) AND DECISIONS OF THE STATE OF NEW YORK. THE PARTIES HERETO INTEND THAT THE PROVISIONS OF SECTION 5-1401 OF THE NEW YORK GENERAL OBLIGATIONS LAW SHALL APPLY TO THIS AGREEMENT. SECTION 19. MISCELLANEOUS. This Agreement may be executed in two or more counterparts, each of which when so executed and delivered shall be an original, but all of which together shall constitute one and the same instrument. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and assigns. This Agreement supersedes all prior agreements and understandings relating to the subject matter hereof. Neither this Agreement nor any term hereof may be changed, waived, discharged or terminated orally, but only by an instrument in writing signed by the party against whom enforcement of the change, waiver, discharge or termination is sought. The headings in this Agreement are for purposes of reference only and shall not limit or otherwise affect the meaning hereof. It is the express intent of the parties hereto that the conveyance of the Mortgage Loans by the Seller to the Purchaser as provided in Section 4 hereof be, and be construed as, a sale of the Mortgage Loans by the Seller to the Purchaser and not as a pledge of the Mortgage Loans by the Seller to the Purchaser to secure a debt or other obligation of the Seller. However, in the event that, notwithstanding the aforementioned intent of the parties, the Mortgage Loans are held to be property of the Seller, then (a) it is the express intent of the parties that such conveyance be deemed a pledge of the Mortgage Loans by the Seller to the Purchaser to secure a debt or other obligation of the Seller and (b) (1) this Agreement shall also be deemed to be a security agreement within the meaning of Articles 8 and 9 of the New York Uniform Commercial Code; (2) the conveyance provided for in Section 4 hereof shall be deemed to be a grant by the Seller to the Purchaser of a security interest in all of the Seller's right, title and interest in and to the Mortgage Loans and all amounts payable to the holders of the Mortgage Loans in accordance with the terms thereof and all proceeds of the conversion, voluntary or involuntary, of the foregoing into cash, instruments, securities or other property, including without limitation all amounts, other than investment earnings, from time to time held or invested in the Collection Account whether in the form of cash, instruments, securities or other property; (3) the possession by the Purchaser or its agent of Mortgage Notes, the related Mortgages and such other items of property that constitute instruments, money, negotiable documents or chattel paper shall be deemed to be "possession" by the secured party for purposes of perfecting the security interest pursuant to the New York Uniform Commercial Code; and (4) notifications to persons holding such property and acknowledgments, receipts or confirmations from persons holding such property shall be deemed notifications to, or acknowledgments, receipts or confirmations from, financial intermediaries, bailees or agents (as applicable) of the Purchaser for the purpose of perfecting such security interest under applicable law. Any assignment of the interest of the Purchaser pursuant to Section 4(d) hereof shall also be deemed to be an assignment of any security interest created hereby. The Seller and the Purchaser shall, to the extent consistent with this Agreement, take such actions as may be necessary to ensure that, if this Agreement were deemed -22- to create a security interest in the Mortgage Loans, such security interest would be deemed to be a perfected security interest of first priority under applicable law and will be maintained as such throughout the term of this Agreement and the Pooling and Servicing Agreement. The NIMS Insurer, if any, shall be a third party beneficiary hereof and may enforce the terms hereof as if a party hereto. -23- IN WITNESS WHEREOF, the Originator, the Purchaser and the Seller have caused their names to be signed by their respective officers thereunto duly authorized as of the date first above written.

The Owner is aware (i) of the tax that would be imposed on transfers of the Class R Certificates to disqualified organizations under the Internal Revenue Code of 1986 that applies to all transfers of the Class R Certificates after March 31, 1988; (ii) that such tax would be on the transferor or, if such transfer is through an agent (which person includes a broker, nominee or middleman) for a non-Permitted Transferee, on the agent; (iii) that the person otherwise liable for the tax shall be relieved of liability for the tax if the transferee furnishes to such person an affidavit that the transferee is a Permitted Transferee and, at the time of transfer, such person does not have actual knowledge that the affidavit is false; and (iv) that each of the Class R Certificates may be a "noneconomic residual interest" within the meaning of proposed Treasury regulations promulgated under the Code and that the transferor of a "noneconomic residual interest" will remain liable for any taxes due with respect to the income on such residual interest, unless no significant purpose of the transfer is to impede the assessment or collection of tax. F-2-1 4. The Owner is aware of the tax imposed on a "pass-through entity" holding the Class R Certificates if, at any time during the taxable year of the pass-through entity, a non-Permitted Transferee is the record holder of an interest in such entity. (For this purpose, a "pass-through entity" includes a regulated investment company, a real estate investment trust or common trust fund, a partnership, trust or estate, and certain cooperatives.) 5. The Owner is aware that the Trustee will not register the transfer of any Class R Certificate unless the transferee, or the transferee's agent, delivers to the Trustee, among other things, an affidavit in substantially the same form as this affidavit. The Owner expressly agrees that it will not consummate any such transfer if it knows or believes that any of the representations contained in such affidavit and agreement are false. 6. The Owner consents to any additional restrictions or arrangements that shall be deemed necessary upon advice of counsel to constitute a reasonable arrangement to ensure that the Class R Certificates will only be owned, directly or indirectly, by an Owner that is a Permitted Transferee. 7. The Owner's taxpayer identification number is ______. 8. The Owner has reviewed the restrictions set forth on the face of the Class R Certificates and the provisions of Section 5.02(d) of the Pooling and Servicing Agreement under which the Class R Certificates were issued (in particular, clauses (iii)(A) and (iii)(B) of Section 5.02(d) which authorize the Trustee to deliver payments to a person other than the Owner and negotiate a mandatory sale by the Trustee in the event that the Owner holds such Certificate in violation of Section 5.02(d)); and that the Owner expressly agrees to be bound by and to comply with such restrictions and provisions. 9. The Owner is not acquiring and will not transfer the Class R Certificates in order to impede the assessment or collection of any tax. 10. The Owner anticipates that it will, so long as it holds the Class R Certificates, have sufficient assets to pay any taxes owed by the holder of such Class R Certificates, and hereby represents to and for the benefit of the person from whom it acquired the Class R Certificates that the Owner intends to pay taxes associated with holding such Class R Certificates as they become due, fully understanding that it may incur tax liabilities in excess of any cash flows generated by the Class R Certificates. 11. The Owner has no present knowledge that it may become insolvent or subject to a bankruptcy proceeding for so long as it holds the Class R Certificates. 12. The Owner has no present knowledge or expectation that it will be unable to pay any United States taxes owed by it so long as any of the Certificates remain outstanding. 13. The Owner is not acquiring the Class R Certificates with the intent to transfer the Class R Certificates to any person or entity that will not have sufficient assets to pay any taxes F-2-2 owed by the holder of such Class R Certificates, or that may become insolvent or subject to a bankruptcy proceeding, for so long as the Class R Certificates remain outstanding. 14. The Owner will, in connection with any transfer that it makes of the Class R Certificates, obtain from its transferee the representations required by Section 5.02(d) of the Pooling and Servicing Agreement under which the Class R Certificate were issued and will not consummate any such transfer if it knows, or knows facts that should lead it to believe, that any such representations are false. 15. The Owner will, in connection with any transfer that it makes of the Class R Certificates, deliver to the Trustee an affidavit, which represents and warrants that it is not transferring the Class R Certificates to impede the assessment or collection of any tax and that it has no actual knowledge that the proposed transferee: (i) has insufficient assets to pay any taxes owed by such transferee as holder of the Class R Certificates; (ii) may become insolvent or subject to a bankruptcy proceeding for so long as the Class R Certificates remains outstanding; and (iii) is not a "Permitted Transferee". 16. The Owner is a citizen or resident of the United States, a corporation, partnership or other entity created or organized in, or under the laws of, the United States or any political subdivision thereof, or an estate or trust whose income from sources without the United States may be included in gross income for United States federal income tax purposes regardless of its connection with the conduct of a trade or business within the United States. 17. The Owner of the Class R Certificate, hereby agrees that in the event that the Trust Fund created by the Pooling and Servicing Agreement is terminated pursuant to Section 9.01 thereof, the undersigned shall assign and transfer to the Holders of the Class CE Certificates (with respect to a termination of REMIC I) any amounts in excess of par received in connection with such termination. Accordingly, in the event of such termination, the Trustee is hereby authorized to withhold any such amounts in excess of par and to pay such amounts directly to the Holders of the Class CE Certificates. This agreement shall bind and be enforceable against any successor, transferee or assigned of the undersigned in the Class R Certificate. In connection with any transfer of the Class R Certificate, the Owner shall obtain an agreement substantially similar to this clause from any subsequent owner.

The Owner understands that the transfer of a Residual Certificate may not be respected for United States income tax purposes (and the Owner may continue to be liable for United States income taxes associated therewith) unless the Owner has conducted such an investigation. 6.
