The return directions for the original Mortgage should indicate, when recorded, mail to the related Seller; 38 (v) the originals of all assumption, modification, consolidation or extension agreements, (or, if an original of any of these documents has not been returned from the recording office, a copy thereof certified by or on behalf of the applicable Seller, the original to be delivered to such Seller forthwith after return from such recording office) with evidence of recording thereon, if any; (vi) the original Assignment of Mortgage as appropriate, in recordable form, for each Mortgage Loan assigned in blank; (vii) the originals of any intervening recorded Assignments of Mortgage, showing a complete chain of assignment from origination to the related Seller, including warehousing assignments, with evidence of recording thereon (or, if an original intervening Assignment of Mortgage has not been returned from the recording office, a copy thereof certified by or on behalf of the applicable Seller, the original to be delivered to the Trustee forthwith after return from such recording office); and (viii) the original mortgage title insurance policy (or in appropriate jurisdictions, attorney's opinion of title and abstract of title). In the event a Seller delivers to the Trustee certified copies of any document or instrument set forth in 2.01(b) because of a delay caused by the public recording office in returning any recorded document, such Seller shall deliver to the Trustee, within 60 days of the Closing Date, an Officer's Certificate which shall (i) identify the recorded document, (ii) state that the recorded document has not been delivered to the Trustee due solely to a delay caused by the public recording office, and (iii) state the amount of time generally required by the applicable recording office to record and return a document submitted for recordation. In the event that in connection with any Mortgage Loan the Depositor cannot deliver (a) the original recorded Mortgage, (b) all interim recorded assignments or (c) the lender's title policy (together with all riders thereto) satisfying the requirements set forth above, concurrently with the execution and delivery hereof because such document or documents have not been returned from the applicable public recording office in the case of clause (a) or (b) above, or because the title policy has not been delivered to the applicable Seller or the Depositor by the applicable title insurer in the case of clause (c) above, the Depositor shall promptly deliver to the Trustee, in the case of clause (a) or (b) above, such original Mortgage or such interim assignment, as the case may be, with evidence of recording indicated thereon upon receipt thereof from the public recording office, or a copy thereof, certified, if appropriate, by the relevant recording office. As promptly as practicable subsequent to such transfer and assignment, and in any event, within thirty (30) days thereafter, the Trustee (at the expense of the Depositor) shall (i) affix the Trustee's name to each Assignment of Mortgage, as the assignee thereof, (ii) cause such assignment to be in proper form for recording in the appropriate public office for real property records within thirty (30) days after receipt thereof and (iii) cause to be delivered for recording in the appropriate public office for real property records the assignments of the Mortgages to the Trustee, except that, with respect to any assignment of a Mortgage as to which the Trustee has not received the information required to prepare such assignment in 39 recordable form, the Trustee's obligation to do so and to deliver the same for such recording shall be as soon as practicable after receipt of such information and in any event within thirty (30) days after the receipt thereof, and the Trustee need not cause to be recorded any assignment which relates to a Mortgage Loan in any jurisdiction under the laws of which, as evidenced by an Opinion of Counsel delivered by the applicable Seller (at such Seller's expense) to the Trustee, acceptable to the Rating Agencies, the recordation of such assignment is not necessary to protect the Trustee's and the Certificateholders' interest in the related Mortgage Loan. If any original Mortgage Note referred to in Section 2.01(b)(i) above cannot be located, the obligations of the Depositor to deliver such documents shall be deemed to be satisfied upon delivery to the Trustee of a photocopy of such Mortgage Note, if available, with a lost note affidavit and indemnity. If any of the original Mortgage Notes for which a lost note affidavit and indemnity was delivered to the Trustee is subsequently located, such original Mortgage Note shall be delivered to the Trustee within three Business Days. (c) The Trustee is authorized to appoint any bank or trust company approved by the Depositor as Custodian of the documents or instruments referred to in this Section 2.01, and to enter into a Custodial Agreement for such purpose and any documents delivered thereunder shall be delivered to the Custodian and any Officer's Certificates delivered with respect thereto shall be delivered to the Trustee and the Custodian. The Trustee is also authorized and directed to enter into the Terms Agreement. (d) It is the express intent of the parties to this Agreement that the conveyance of the Mortgage Loans by the Depositor to the Trustee as provided in this Section 2.01 be, and be construed as, a sale of the Mortgage Loans by the Depositor to the Trustee. It is, further, not the intention of the parties to this Agreement that such conveyance be deemed a pledge of the Mortgage Loans by the Depositor to the Trustee to secure a debt or other obligation of the Depositor. However, in the event that, notwithstanding the intent of the parties to this Agreement, the Mortgage Loans are held to be the property of the Depositor, or if for any other reason this Agreement is held or deemed to create a security interest in the Mortgage Loans then (a) 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; (b) the conveyance provided for in this Section 2.01 shall be deemed to be a grant by the Depositor to the Trustee for the benefit of the Certificateholders of a security interest in all of the Depositor'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 Certificate Account, whether in the form of cash, instruments, securities or other property; (c) the possession by the Trustee or any Custodian of such items of property and such other items of property as constitute instruments, money, negotiable documents or chattel paper shall be deemed to be "in possession by the secured party" for purposes of perfecting the security interest pursuant to Section 9-305 of the New York Uniform Commercial Code; and (d) 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 Trustee for the benefit of the Certificateholders for the purpose of perfecting such security interest under 40 applicable law (except that nothing in this clause (d) shall cause any person to be deemed to be an agent of the Trustee for any purpose other than for perfection of such security interests unless, and then only to the extent, expressly appointed and authorized by the Trustee in writing). The Depositor and the Trustee, upon directions from the Depositor, shall, to the extent consistent with this Agreement, take such actions as may be necessary to ensure that, if this Agreement were deemed to create a security interest in the 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. SECTION 2.02 Acceptance by the Trustee. (a) The Trustee acknowledges receipt of the documents identified in the Initial Certification in the form annexed hereto as Exhibit I and declares that it holds and will hold such documents and the other documents delivered to it constituting the Mortgage Files, and that it holds or will hold such other assets as are included in the Trust Fund, in trust for the exclusive use and benefit of all present and future Certificateholders. The Trustee acknowledges that its Custodian will maintain possession of the Mortgage Notes in the State of Texas, unless otherwise permitted by the Rating Agencies. The Trustee agrees to execute and deliver on the Closing Date to the Depositor, each Seller and Servicer an Initial Certification in the form annexed hereto as Exhibit I with any applicable exception noted on an attachment thereto. Based on its review and examination, and only as to the documents identified in such Initial Certification, the Trustee acknowledges that such documents appear regular on their face and relate to such Mortgage Loan. The Trustee shall be under no duty or obligation to inspect, review or examine said documents, instruments, certificates or other papers to determine that the same are genuine, enforceable or appropriate for the represented purpose or that they have actually been recorded in the real estate records or that they are other than what they purport to be on their face. Not later than 90 days after the Closing Date, the Trustee shall deliver to the Depositor, each Seller and Servicer a Final Certification in the form annexed hereto as Exhibit J, with any applicable exceptions noted on an attachment thereto. If, in the course of such review, the Trustee finds any document constituting a part of a Mortgage File which does not meet the requirements of Section 2.01, the Trustee shall list such as an exception on an attachment to the Final Certification; provided, however, that the Trustee shall not make any determination as to whether (i) any endorsement is sufficient to transfer all right, title and interest of the party so endorsing, as noteholder or assignee thereof, in and to that Mortgage Note or (ii) any assignment is in recordable form or is sufficient to effect the assignment of and transfer to the assignee thereof under the mortgage to which the assignment relates. The related Seller shall promptly correct or cure such defect within 90 days from the date it was so notified of such defect and, if such Seller does not correct or cure such defect within such period, such Seller shall either (a) substitute for the related Mortgage Loan a Qualified Substitute Mortgage Loan, which substitution shall be accomplished in the manner and subject to the conditions set forth in Section 2.03, or (b) purchase such Mortgage Loan from the 41 Trustee within 90 days from the date such Seller was notified of such defect in writing at the Purchase Price of such Mortgage Loan; or such longer period not to exceed 720 days from the Closing Date if the substitution or repurchase of a Mortgage Loan pursuant to this provision is required by reason of a delay in delivery of any documents by the appropriate recording office; provided, however, that a Seller shall have no liability for recording any Assignment of Mortgage in favor of the Trustee or for the Trustee's failure to record such Assignment of Mortgage, and provided, further, that no Seller shall be obligated to repurchase or cure any Mortgage Loan solely as a result of the Trustee's failure to record such Assignment of Mortgage. The Trustee shall deliver written notice to each Rating Agency within 270 days from the Closing Date indicating each Mortgage (a) which has not been returned by the appropriate recording office or (b) as to which there is a dispute as to location or status of such Mortgage. Such notice shall be delivered every 90 days thereafter until the related Mortgage Loan is returned to the Trustee. Any such substitution pursuant to (a) above or purchase pursuant to (b) above shall not be effected prior to the delivery to the Trustee of the Opinion of Counsel required by Section 2.05 hereof, if any, and any substitution pursuant to (a) above shall not be effected prior to the additional delivery to the Trustee of a Request for Release substantially in the form of Exhibit K. No substitution is permitted to be made in any calendar month after the Determination Date for such month. The Purchase Price for any such Mortgage Loan shall be deposited by the applicable Seller in the Certificate Account on the date of repurchase and, upon receipt of such deposit and certification with respect thereto in the form of Exhibit K hereto, the Trustee shall release the related Mortgage File to such Seller and shall execute and deliver at such entity's request such instruments of transfer or assignment prepared by such entity, in each case without recourse, as shall be necessary to vest in such entity, or a designee, the Trustee's interest in any Mortgage Loan released pursuant hereto. (b) It is understood and agreed that the obligation of each Seller to cure, substitute for or to repurchase any Mortgage Loan which does not meet the requirements of Section 2.01 shall constitute the sole remedy respecting such defect available to the Trustee, the Depositor and any Certificateholder against such Seller. SECTION 2.03 Representations and Warranties of the Sellers and Servicers. (a) Each of DLJMC, in its capacity as Seller, ABN AMRO, in its capacity as Servicer and Seller, WMMSC, in its capacity as Servicer, and Vesta, in its capacity as Servicer and Special Servicer, hereby makes the representations and warranties applicable to it set forth in Schedule IIA, IIB, IIC or IID, as applicable hereto, and by this reference incorporated herein, to the Depositor and the Trustee, as of the Closing Date, or if so specified therein, as of the Cut-off Date or such other date as may be specified. (b) Each of DLJMC and ABN AMRO, in their capacities as Sellers, hereby makes the representations and warranties set forth in Schedule IIIA and IIIB as applicable hereto applicable to the DLJ Loans and the ABN AMRO Loans, respectively, and by this reference incorporated herein, to the Depositor and the Trustee, as of the Closing Date, or if so specified therein, as of the Cut-off Date or such other date as may be specified. 42 (c) Upon discovery by any of the parties hereto of a breach of a representation or warranty made pursuant to Section 2.03(b) that materially and adversely affects the interests of the Certificateholders in any Mortgage Loan, the party discovering such breach shall give prompt notice thereof to the other parties. Each Seller hereby covenants that within 90 days of the earlier of its discovery or its receipt of written notice from any party of a breach of any representation or warranty made by it pursuant to Section 2.03(b) which materially and adversely affects the interests of the Certificateholders in any Mortgage Loan sold by such Seller to the Trust, it shall cure such breach in all material respects, and if such breach is not so cured, shall, (i) if such 90-day period expires prior to the second anniversary of the Closing Date, remove such Mortgage Loan (a "Deleted Mortgage Loan") from the Trust Fund and substitute in its place a Qualified Substitute Mortgage Loan, in the manner and subject to the conditions set forth in this Section; or (ii) repurchase the affected Mortgage Loan or Mortgage Loans from the Trustee at the Purchase Price in the manner set forth below; provided, however, that any such substitution pursuant to (i) above shall not be effected prior to the delivery to the Trustee of the Opinion of Counsel required by Section 2.05 hereof, if any, and any such substitution pursuant to (i) above shall not be effected prior to the additional delivery to the Trustee of a Request for Release substantially in the form of Exhibit K relating to the Deleted Mortgage Loan and the Mortgage File for any such Qualified Substitute Mortgage Loan. The related Seller shall promptly reimburse the Trustee for any actual out-of-pocket expenses reasonably incurred by the Trustee in respect of enforcing the remedies for such breach. With respect to any representation and warranties described in this Section which are made to the best of a Seller's knowledge if it is discovered by either the Depositor, any Seller, any Servicer or the Trustee that the substance of such representation and warranty is inaccurate and such inaccuracy materially and adversely affects the value of the related Mortgage Loan or the interests of the Certificateholders therein, notwithstanding such Seller's lack of knowledge with respect to the substance of such representation or warranty, such inaccuracy shall be deemed a breach of the applicable representation or warranty. With respect to any Qualified Substitute Mortgage Loan or Loans, the applicable Seller shall deliver to the Trustee for the benefit of the Certificateholders the Mortgage Note, the Mortgage, the related assignment of the Mortgage, and such other documents and agreements as are required by Section 2.01(b), with the Mortgage Note endorsed and the Mortgage assigned as required by Section 2.01. No substitution is permitted to be made in any calendar month after the Determination Date for such month. Scheduled Payments due with respect to Qualified Substitute Mortgage Loans in the month of substitution shall not be part of the Trust Fund and will be retained by the applicable Seller on the next succeeding Distribution Date. For the month of substitution, distributions to Certificateholders will include the monthly payment due on any Deleted Mortgage Loan for such month and thereafter such Seller shall be entitled to retain all amounts received in respect of such Deleted Mortgage Loan. The applicable Seller shall amend the Mortgage Loan Schedule for the benefit of the Certificateholders to reflect the removal of such Deleted Mortgage Loan and the substitution of the Qualified Substitute Mortgage Loan or Loans and such Seller shall deliver the amended Mortgage Loan Schedule to the Trustee and the Servicers. Upon such substitution, the Qualified Substitute Mortgage Loan or Loans shall be subject to the terms of this Agreement in all respects, and the applicable Seller shall be deemed to have made with respect to such Qualified Substitute Mortgage Loan or Loans, as of the date of substitution, the representations and warranties made pursuant to Section 2.03(b) with respect to such Mortgage Loan. Upon any such substitution and the deposit to the Certificate Account of 43 the amount required to be deposited therein in connection with such substitution as described in the following paragraph, the Trustee shall release the Mortgage File held for the benefit of the Certificateholders relating to such Deleted Mortgage Loan to the applicable Seller and shall execute and deliver at such Seller's direction such instruments of transfer or assignment prepared by such Seller, in each case without recourse, representation or warranty as shall be necessary to vest title in such Seller, or its designee, the Trustee's interest in any Deleted Mortgage Loan substituted for pursuant to this Section 2.03. For any month in which a Seller substitutes one or more Qualified Substitute Mortgage Loans for one or more Deleted Mortgage Loans, the applicable Servicer shall determine the amount (if any) by which the aggregate principal balance of all such Qualified Substitute Mortgage Loans (based on information provided by the substituting party) as of the date of substitution is less than the aggregate Stated Principal Balance of all such Deleted Mortgage Loans (after application of the scheduled principal portion of the monthly payments due in the month of substitution). The amount of such shortage (the "Substitution Adjustment Amount") plus an amount equal to the aggregate of any unreimbursed Advances with respect to such Deleted Mortgage Loans shall be deposited in the Collection Account by the related Seller on the date of substitution. In the event that a Seller shall have repurchased a Mortgage Loan, the Purchase Price therefor shall be deposited in the Certificate Account on or before the Business Day immediately preceding the Distribution Date in the month following the month during which such Seller became obligated hereunder to repurchase or replace such Mortgage Loan and upon such deposit of the Purchase Price, the delivery of the Opinion of Counsel if required by Section 2.05 and receipt of a Request for Release in the form of Exhibit K hereto, the Trustee shall release the related Mortgage File held for the benefit of the Certificateholders to such Person, and the Trustee shall execute and deliver at such Person's direction such instruments of transfer or assignment prepared by such Person, in each case without recourse, representation or warranty as shall be necessary to transfer title from the Trustee. It is understood and agreed that the obligation under this Agreement of any Person to cure, repurchase or substitute any Mortgage Loan as to which a breach has occurred and is continuing shall constitute the sole remedy against such Persons respecting such breach available to Certificateholders, the Depositor or the Trustee on their behalf. The representations and warranties made pursuant to this Section 2.03 shall survive delivery of the respective Mortgage Files to the Trustee for the benefit of the Certificateholders. SECTION 2.04 Representations and Warranties of the Depositor as to the Mortgage Loans. The Depositor hereby represents and warrants to the Trustee with respect to the Mortgage Loans that, as of the Closing Date, assuming good title has been conveyed to the Depositor, the Depositor had good title to the Mortgage Loans and Mortgage Notes, and did not encumber the Mortgage Loans during its period of ownership thereof, other than as contemplated by the Agreement. 44 It is understood and agreed that the representations and warranties set forth in this Section 2.04 shall survive delivery of the Mortgage Files to the Trustee. SECTION 2.05 Delivery of Opinion of Counsel in Connection with Substitutions. Notwithstanding any contrary provision of this Agreement, no substitution pursuant to Section 2.02 or 2.03 shall be made more than 90 days after the Closing Date unless the applicable Seller delivers to the Trustee an Opinion of Counsel, which Opinion of Counsel shall not be at the expense of either the Trustee or the Trust Fund, addressed to the Trustee, to the effect that such substitution will not (i) result in the imposition of the tax on "prohibited transactions" on the Trust Fund or contributions after the Startup Date, as defined in Sections 860F(a)(2) and 860G(d) of the Code, respectively, or (ii) cause the REMIC hereunder to fail to qualify as a REMIC at any time that any Certificates are outstanding. SECTION 2.06 Issuance of Certificates. The Trustee acknowledges the assignment to it of the Mortgage Loans together with the assignment to it of all other assets included in the Trust Fund, receipt of which is hereby acknowledged. Concurrently with such assignment and delivery and in exchange therefor, the Trustee, pursuant to the written request of the Depositor executed by an officer of the Depositor, has executed the Certificates and caused them to be authenticated and delivered to or upon the order of the Depositor in authorized denominations which evidence ownership of the Trust Fund. The rights of the Holders of such Certificates to receive distributions from the Trust Fund and all ownership interests of the Holders of the Certificates in such distributions shall be as set forth in this Agreement. SECTION 2.07 REMIC Provisions. (a) The Depositor hereby elects and authorizes the Trustee to treat the Trust Fund as a REMIC under the Code and, if necessary, under applicable state law. Such election will be made on Form 1066 or other appropriate federal tax or information return (including Form 8811) or any appropriate state return (x) for the taxable year ending on the last day of the calendar year in which the Certificates are issued and (y) for the taxable year ending on the last day of the calendar year in which Certificates are first sold to a third party. The Closing Date is hereby designated as the "startup day" of the REMIC within the meaning of Section 860G(a)(9) of the Code. The "regular interests" (within the meaning of Section 860G of the Code) in the REMIC shall consist of the Regular Certificates and the "Class AR Certificates shall represent the beneficial ownership of the "residual interest" in each REMIC. The Depositor and the Trustee shall not permit the creation of any "interests" (within the meaning of Section 860G of the Code) in the REMIC other than the Certificates. (b) The Trustee on behalf of the Holders of the Class AR Certificates, shall act as agent for the Class AR Certificateholder as the "tax matters person" (within the meaning of the REMIC Provisions) for the REMIC, in the manner provided under Treasury regulations section 1.860F-4(d) and temporary Treasury regulations section 301.6231(a)(7)-1T. By its acceptance of a Class AR Certificate, each Holder thereof shall have agreed to such appointment and shall have 45 consented to the appointment of the Trustee as its agent to act on behalf of each REMIC pursuant to the specific duties outlined herein. (c) A Holder of the Class AR Certificates, by the purchase of such Certificates, shall be deemed to have agreed to timely pay, upon demand by the Trustee, the amount of any minimum California state franchise taxes due with respect to the REMIC under Sections 23151(a) and 23153(a) of the California Revenue and Taxation Code. Notwithstanding the foregoing, the Trustee shall be authorized to retain the amount of such tax from amounts otherwise distributable to such Holder in the event such Holder does not promptly pay such amount upon demand by the Trustee. In the event that any other federal, state or local tax is imposed, including without limitation taxes imposed on a "prohibited transaction" of a REMIC as defined in Section 860F of the Code, such tax shall be charged against amounts otherwise available for distribution to the applicable Holder of a Class AR Certificate and then against amounts otherwise available for distribution to the Holders of Regular Certificates in accordance with the provisions set forth in Section 4.01. The Trustee shall promptly deposit in the Certificate Account any amount of "prohibited transaction" tax that results from a breach of the Trustee's duties under this Agreement. The Servicer shall promptly deposit in the Certificate Account any amount of "prohibited transaction" tax that results from a breach of the Servicer's duties under this Agreement. (d) The Trustee shall act as attorney-in-fact and as agent on behalf of the tax matters person of the REMIC and in such capacity the Trustee shall: (i) prepare, sign and file, or cause to be prepared, signed and filed, federal and state tax returns using a calendar year as the taxable year for the REMIC when and as required by the REMIC Provisions and other applicable federal income tax laws as the direct representative of the REMIC in compliance with the Code and shall provide copies of such returns as required by the Code; (ii) make an election, on behalf of the REMIC, to be treated as a REMIC on the federal tax return of such REMIC for its first taxable year, in accordance with the REMIC Provisions; and (iii) prepare and forward, or cause to be prepared and forwarded, to the Certificateholders and to any governmental taxing authority all information reports as and when required to be provided to them in accordance with the REMIC Provisions. The expenses of preparing and filing such returns shall be borne by the Trustee. The Depositor and Servicer shall provide on a prompt and timely basis to the Trustee or its designee such information with respect to the REMIC as is in their possession and reasonably required or requested by the Trustee to enable it to perform its obligations under this subsection. In its capacity as attorney-in-fact and as agent on behalf of the tax matters person, the Trustee shall also: (A) act on behalf of the REMIC in relation to any tax matter or controversy involving the Trust Fund, (B) represent the Trust Fund in any administrative or judicial proceeding relating to an examination or audit by any governmental taxing authority with respect thereto and (C) cause to be paid solely from the sources provided herein the amount of any taxes imposed on the REMIC when and as the same shall be due and payable (but such obligation shall not prevent the Trustee or any other appropriate Person from contesting any such tax in appropriate proceedings and shall not prevent the Trustee from withholding payment of such tax, if permitted by law, pending the outcome of such proceedings). (e) The Trustee shall (i) provide to any transferor of a Class AR Certificate such information as is necessary for the application of any tax relating to the transfer of a Class AR 46 Certificate to any Person who is not a permitted transferee, (ii) forward 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 and (iii) to the Internal Revenue Service the name, title, address and telephone number of the person who will serve as the representative of the REMIC. (f) The Trustee, the Depositor and the Holder of the Class AR Certificates shall take any action or cause the Trust Fund to take any action necessary to create or maintain the status of the REMIC as a REMIC under the REMIC Provisions and shall assist each other as necessary to create or maintain such status. Neither the Trustee nor the Holder of the Class AR Certificates shall take any action, cause the Trust Fund to take any action or fail to take (or fail to cause the Trust Fund to take) any action that, under the REMIC Provisions, if taken or not taken, as the case may be, could (i) endanger the status of the REMIC as a REMIC or (ii) result in the imposition of a tax upon a REMIC (including, but not limited to, the tax on prohibited transactions as defined in Code Section 860F(a)(2) and the tax on prohibited contributions set forth in Section 860G(d) of the Code) (either such event, an "Adverse REMIC Event") unless the Trustee has received an Opinion of Counsel (at the expense of the party seeking to take such action) to the effect that the contemplated action will not endanger such status or result in the imposition of such a tax. The Trustee shall not take or fail to take any action (whether or not authorized hereunder) as to which a Servicer or Depositor 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. In addition, prior to taking any action with respect to a REMIC or its assets, or causing the REMIC created hereunder to take any action, which is not expressly permitted under the terms of this Agreement, the Trustee will consult with the Servicers and Depositor or their designees, in writing, with respect to whether such action could cause an Adverse REMIC Event to occur with respect to the REMIC created hereunder and the Trustee shall not take any such action or cause the REMIC to take any such action as to which any Servicer or Depositor has advised it in writing that an Adverse REMIC Event could occur. In addition, prior to taking any action with respect to the REMIC created hereunder or the assets therein, or causing the REMIC created hereunder to take any action, which is not expressly permitted under the terms of this Agreement, the Holder of the Class AR Certificates will consult with the Trustee or its designee, in writing, with respect to whether such action could cause an Adverse REMIC Event to occur with respect to the REMIC created hereunder, and no such Person shall take any action or cause the Trust Fund to take any such action as to which the Trustee has advised it in writing that an Adverse REMIC Event could occur. The Trustee may consult with counsel to make such written advice, and the cost of same shall be borne by the party seeking to take action not permitted by this Agreement. At all times as may be required by the Code, the Trustee will to the extent within its control and the scope of its duties more specifically set forth herein, maintain substantially all of the assets of the REMIC as "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. 47 (g) In the event that any tax is imposed on "prohibited transactions" of the REMIC, as defined in Section 860F(a)(2) of the Code, on "net income from foreclosure property" of such REMIC, as defined in Section 860G(c) of the Code, on any contributions to the 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 a Servicer, if such tax arises out of or results from a breach by such Servicer of any of its obligations under this Agreement or if such Servicer has in its sole discretion determined to indemnify the Trust Fund against such tax, (ii) to the Trustee, if such tax arises out of or results from a breach by the Trustee of any of its obligations under this Article II, or (iii) otherwise against amounts on deposit in the Collection Account as provided by Section 3.09 and on the Distribution Date(s) following such reimbursement the aggregate of such taxes shall be allocated in reduction of the Interest Distribution Amount on each Class entitled thereto in the same manner as if such taxes constituted a Prepayment Interest Shortfall. (h) The Trustee shall, for federal income tax purposes, maintain books and records with respect to the REMIC on a calendar year and on an accrual basis or as otherwise may be required by the REMIC Provisions. (i) Following the Startup Day, no Servicer nor the Trustee shall accept any contributions of assets to the REMIC created hereunder unless (subject to 2.07(f)) such Servicer and the Trustee shall have received an Opinion of Counsel (at the expense of the party seeking to make such contribution) to the effect that the inclusion of such assets in the REMIC will not cause that REMIC to fail to qualify as a REMIC at any time that any Certificates are outstanding, or subject the REMIC to any tax under the REMIC Provisions or other applicable provisions of federal, state and local law or ordinances. (j) No Servicer nor the Trustee shall (subject to Section 2.07(f)) enter into any arrangement by which the REMIC will receive a fee or other compensation for services nor permit the REMIC to receive any income from assets other than "qualified mortgages" as defined in Section 860G(a)(3) of the Code or "permitted investments" as defined in Section 860G(a)(5) of the Code. (k) Within 30 days after the Closing Date, the Trustee shall prepare and file with the Internal Revenue Service Form 8811, "Information Return for Real Estate Mortgage Investment Conduits (REMIC) and Issuers of Collateralized Debt Obligations" for the REMIC. (l) Neither the Trustee nor any Servicer shall sell, dispose of or substitute for any of the Mortgage Loans (except in connection with (i) the default, imminent default or 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 the REMIC created hereunder, (iii) the termination of the REMIC created hereunder pursuant to Article X of this Agreement or (iv) a purchase of Mortgage Loans pursuant to Article II or III of this Agreement) nor acquire any assets for the REMIC, nor sell or dispose of any investments in the Collection Account or the Certificate Account for gain nor accept any contributions to the REMIC after the Closing Date (a) unless it has received an Opinion of Counsel that such sale, disposition, substitution or acquisition will not affect adversely the status of the REMIC created hereunder as a REMIC or 48 (b) unless such Servicer has determined in its sole discretion to indemnify the Trust Fund against such tax. (m) In order to enable the Trustee to perform its duties as set forth herein, the Depositor shall provide, or cause to be provided to the Trustee, within ten days after the Closing Date, all information or data that the Trustee determines to be relevant for tax purposes to the valuations and offering prices of the Certificates, including, without limitation, the price, yield, prepayment assumption and projected cash flows of the Certificates and the Mortgage Loans and the Trustee shall be entitled to rely upon any and all such information and data in the performance of its duties set forth herein. Thereafter, each Servicer shall provide, promptly upon request therefor, any such additional information or data that the Trustee may from time to time reasonably request in order to enable the Trustee to perform its duties as set forth herein and the Trustee shall be entitled to rely upon any and all such information and data in the performance of its duties set forth herein. DLJMC shall indemnify the Trustee and hold it harmless for any loss, liability, damage, claim or expense of the Trustee, pursuant to, and in accordance with, Section 9.05 of this Agreement, arising from any failure of the Depositor to provide, or cause to be provided, accurate information or data to the Trustee on a timely basis. The indemnification provisions hereunder shall survive the termination of this Agreement and shall extend to any co-trustee appointed pursuant to this Agreement. SECTION 2.08 Covenants of each Servicer. Each Servicer hereby covenants to the Depositor and the Trustee as follows: (a) Such Servicer shall comply in the performance of its obligations under this Agreement with all reasonable rules and requirements of the insurer under each Primary Insurance Policy; and (b) No written information, certificate of an officer, statement furnished in writing or written report delivered to the Depositor, any affiliate of the Depositor or the Trustee and prepared by such Servicer pursuant to this Agreement will contain any untrue statement of a material fact. 49 ARTICLE III ADMINISTRATION AND SERVICING OF MORTGAGE LOANS SECTION 3.01 Servicers to Service Mortgage Loans. For and on behalf of the Certificateholders, each Servicer shall service and administer the Mortgage Loans in accordance with the terms of this Agreement and with Accepted Servicing Practices. The obligations of each of ABN AMRO, Vesta and WMMSC hereunder to service and administer the Mortgage Loans shall be limited to the ABN AMRO Serviced Mortgage Loans, the Vesta Serviced Mortgage Loans and the WMMSC Serviced Mortgage Loans, respectively; and with respect to the duties and obligations of each Servicer, references herein to related "Mortgage Loans" shall be limited to the WMMSC Serviced Mortgage Loans (and the related proceeds thereof and related REO Properties), in the case of WMMSC, the ABN AMRO Serviced Mortgage Loans (and the related proceeds thereof and related REO Properties) in the case of ABN AMRO, and the Vesta Serviced Mortgage Loans (and the related proceeds thereof and related REO Properties) in the case of Vesta; and in no event shall any Servicer have any responsibility or liability with respect to any of the other Mortgage Loans. In connection with such servicing and administration, each Servicer shall have full power and authority, acting alone and/or through Subservicers as provided in Section 3.02 hereof, to do or cause to be done any and all things that it may deem necessary or desirable in connection with such servicing and administration, including but not limited to, the power and authority, subject to the terms hereof (i) to execute and deliver, on behalf of the Certificateholders and the Trustee, customary consents or waivers and other instruments and documents, (ii) to consent to transfers of any Mortgaged Property and assumptions of the Mortgage Notes and related Mortgages (but only in the manner provided in this Agreement), (iii) to collect any Insurance Proceeds and other Liquidation Proceeds, and (iv) to effectuate foreclosure or other conversion of the ownership of the Mortgaged Property securing any Mortgage Loan; provided that a Servicer shall not take any action that is inconsistent with or prejudices the interests of the Trust Fund or the Certificateholders in any Mortgage Loan or the rights and interests of the Depositor, the Trustee or the Certificateholders under this Agreement. Each Servicer shall represent and protect the interests of the Trust Fund in the same manner as it protects its own interests in mortgage loans in its own portfolio in any claim, proceeding or litigation regarding a Mortgage Loan, and shall not make or permit any modification, waiver or amendment of any Mortgage Loan which would cause the REMIC created hereunder to fail to qualify as a REMIC or result in the imposition of any tax under Section 860F(a) or Section 860G(d) of the Code. Without limiting the generality of the foregoing, each Servicer, in its own name or in the name of the Depositor and the Trustee, is hereby authorized and empowered by the Depositor and the Trustee, when such Servicer believes it appropriate in its reasonable judgment, to execute and deliver, on behalf of the Trustee, the Depositor, the Certificateholders or any of them, any and all instruments of satisfaction or cancellation, or of partial or full release or discharge and all other comparable instruments, with respect to the Mortgage Loans, and with respect to the Mortgaged Properties held for the benefit of the Certificateholders. Each Servicer shall prepare and deliver to the Depositor and/or the Trustee such documents requiring execution and delivery by either or both of them as are necessary or appropriate to enable such Servicer to service and administer the Mortgage Loans to the extent 50 that such Servicer is not permitted to execute and deliver such documents pursuant to the preceding sentence. Upon receipt of such documents, the Depositor and/or the Trustee shall execute such documents and deliver them to such Servicer. In accordance with the standards of the preceding paragraph and unless determined in good faith to be a Nonrecoverable Advance, each Servicer shall advance or cause to be advanced funds as necessary for the purpose of effecting the payment of taxes and assessments on the Mortgaged Properties, which advances shall be reimbursable in the first instance from related collections from the Mortgagors pursuant to Section 3.06, and further as provided in Section 3.08. The costs incurred by a Servicer, if any, in effecting the timely payments of taxes and assessments on the Mortgaged Properties and related insurance premiums shall not, for the purpose of calculating monthly distributions to the Certificateholders, be added to the Stated Principal Balances of the related Mortgage Loans, notwithstanding that the terms of such Mortgage Loans so permit. Each Servicer hereby acknowledges that, to the extent such Servicer has previously serviced some or all of the Mortgage Loans pursuant to another servicing agreement, the provisions contained in this Agreement shall supersede the provisions contained in such other servicing agreement from and after the Closing Date. SECTION 3.02 Subservicing; Enforcement of the Obligations of Subservicers. (a) The Mortgage Loans may be subserviced by a Subservicer on behalf of the related Servicer in accordance with the servicing provisions of this Agreement, provided that the Subservicer is a FNMA-approved lender or a FHLMC seller/servicer in good standing. A Servicer may perform any of its servicing responsibilities hereunder or may cause the Subservicer to perform any such servicing responsibilities on its behalf, but the use by such Servicer of the Subservicer shall not release such Servicer from any of its obligations hereunder and such Servicer shall remain responsible hereunder for all acts and omissions of the Subservicer as fully as if such acts and omissions were those of such Servicer. Each Servicer shall pay all fees and expenses of any Subservicer engaged by such Servicer from its own funds. Notwithstanding the foregoing, each Servicer shall be entitled to outsource one or more separate servicing functions to a Person (each, an "Outsourcer") that does not meet the eligibility requirements for a Subservicer, so long as such outsourcing does not constitute the delegation of such Servicer's obligation to perform all or substantially all of the servicing of the related Mortgage Loans to such Outsourcer. In such event, the use by a Servicer of any such Outsourcer shall not release the related Servicer from any of its obligations hereunder and such Servicer shall remain responsible hereunder for all acts and omissions of such Outsourcer as fully as if such acts and omissions were those of such Servicer, and such Servicer shall pay all fees and expenses of the Outsourcer from such Servicer's own funds. (b) At the cost and expense of a Servicer, without any right of reimbursement from the Depositor, Trustee, or the applicable Collection Account, such Servicer shall be entitled to terminate the rights and responsibilities of its Subservicer and arrange for any servicing responsibilities to be performed by a successor Subservicer meeting the requirements set forth in 51 Section 3.02(a), provided, however, that nothing contained herein shall be deemed to prevent or prohibit such Servicer, at such Servicer's option, from electing to service the related Mortgage Loans itself. In the event that a Servicer's responsibilities and duties under this Agreement are terminated pursuant to Section 8.01, and if requested to do so by the Trustee, such Servicer shall at its own cost and expense terminate the rights and responsibilities of its Subservicer as soon as is reasonably possible. Each Servicer shall pay all fees, expenses or penalties necessary in order to terminate the rights and responsibilities of its Subservicer from such Servicer's own funds without any right of reimbursement from the Depositor, Trustee, or the applicable Collection Account. (c) Notwithstanding any of the provisions of this Agreement relating to agreements or arrangements between a Servicer and its Subservicer, a Servicer and its Outsourcer, or any reference herein to actions taken through the Subservicer, the Outsourcer, or otherwise, no Servicer shall be relieved of its obligations to the Depositor, Trustee or Certificateholders and shall be obligated to the same extent and under the same terms and conditions as if it alone were servicing and administering the related Mortgage Loans. Each Servicer shall be entitled to enter into an agreement with its Subservicer and Outsourcer for indemnification of such Servicer or Outsourcer, as applicable, by such Subservicer and nothing contained in this Agreement shall be deemed to limit or modify such indemnification. For purposes of this Agreement, a Servicer shall be deemed to have received any collections, recoveries or payments with respect to the related Mortgage Loans that are received by a related Subservicer regardless of whether such payments are remitted by the Subservicer to such Servicer. Any Subservicing Agreement and any other transactions or services relating to the Mortgage Loans involving a Subservicer shall be deemed to be between the Subservicer, and the related Servicer alone, and the Depositor, the Trustee and the other Servicers shall have no obligations, duties or liabilities with respect to a Subservicer including no obligation, duty or liability of the Depositor, Trustee or other Servicers to pay a Subservicer's fees and expenses. SECTION 3.03 Notification of Adjustments. With respect to each Mortgage Loan, the related Servicer shall adjust the Mortgage Rate on the related Adjustment Date in compliance with the requirements of applicable law and the related Mortgage and Mortgage Note. The related Servicer shall execute and deliver any and all necessary notices required under applicable law and the terms of the related Mortgage Note and Mortgage regarding the Mortgage Rate adjustments. Upon the discovery by the related Servicer or the receipt of notice from the Trustee that such Servicer has failed to adjust a Mortgage Rate in accordance with the terms of the related Mortgage Note, that Servicer shall immediately deposit in the Certificate Account from its own funds the amount of any interest loss or deferral caused the Trustee thereby. SECTION 3.04 Trustee to Act as Servicer. In the event that any Servicer shall for any reason no longer be a Servicer hereunder (including by reason of an Event of Default), the Trustee or its successor shall 52 thereupon assume all of the rights and obligations of such Servicer hereunder arising thereafter (except that the Trustee shall not be (i) liable for losses of such Servicer pursuant to Section 3.09 hereof or any acts or omissions of the related predecessor Servicer hereunder, (ii) obligated to make Advances if it is prohibited from doing so by applicable law, (iii) obligated to effectuate repurchases or substitutions of Mortgage Loans hereunder including, but not limited to, repurchases or substitutions of Mortgage Loans pursuant to Section 2.02 or 2.03 hereof or (iv) deemed to have made any representations and warranties of such Servicer hereunder). Any such assumption shall be subject to Section 8.02 hereof. Each Servicer shall, upon request of the Trustee, but at the expense of such Servicer, deliver to the assuming party all documents and records relating to each Subservicing Agreement or substitute Subservicing Agreement and the Mortgage Loans then being serviced thereunder and hereunder by such Servicer and an accounting of amounts collected or held by it and otherwise use its best efforts to effect the orderly and efficient transfer of the substitute Subservicing Agreement to the assuming party. SECTION 3.05 Collection of Mortgage Loans; Collection Accounts; Certificate Account. (a) Continuously from the date hereof until the principal and interest on all Mortgage Loans have been paid in full or such Mortgage Loans have become Liquidated Mortgage Loans, each Servicer shall proceed in accordance with the customary and usual standards of practice of prudent mortgage loan servicers to collect all payments due under each of the related Mortgage Loans when the same shall become due and payable to the extent consistent with this Agreement and the terms and provisions of any related Primary Insurance Policy and shall take special care with respect to Mortgage Loans for which a Servicer collects escrow payments in ascertaining and estimating Escrow Payments and all other charges that will become due and payable with respect to the Mortgage Loans and the Mortgaged Properties, to the end that the installments payable by the Mortgagors will be sufficient to pay such charges as and when they become due and payable. Consistent with the foregoing, each Servicer may in its discretion (i) waive any late payment charge or any prepayment charge or penalty interest in connection with the prepayment of a Mortgage Loan and (ii) extend the due dates for payments due on a Mortgage Note for a period not greater than 180 days; provided, however, that such Servicer cannot extend the maturity of any such Mortgage Loan past the date on which the final payment is due on the latest maturing Mortgage Loan as of the Cut-off Date. In the event of any such arrangement, the related Servicer shall make Advances on the related Mortgage Loan in accordance with the provisions of Section 5.01 during the scheduled period in accordance with the amortization schedule of such Mortgage Loan without modification thereof by reason of such arrangements. No Servicer shall be required to institute or join in litigation with respect to collection of any payment (whether under a Mortgage, Mortgage Note or otherwise or against any public or governmental authority with respect to a taking or condemnation) if it reasonably believes that enforcing the provision of the Mortgage or other instrument pursuant to which such payment is required is prohibited by applicable law. (b) Each Servicer shall segregate and hold all funds collected and received pursuant to a Mortgage Loan separate and apart from any of its own funds and general assets and shall establish and maintain one or more Collection Accounts, in the form of time deposit or 53 demand accounts, titled "[Servicer's name], in trust for the Holders of Credit Suisse First Boston Mortgage Securities Corp., Mortgage-Backed Pass-Through Certificates, Series 2001-AR19" or, if established and maintained by a Subservicer on behalf of a Servicer, "[Subservicer's name], in trust for [Servicer's name]" or "[Subservicer's name], as agent, trustee and/or bailee of principal and interest custodial account for [Servicer's name], its successors and assigns, for various owners of interest in [Servicer's name] mortgage-backed pools." Each Collection Account shall be an Eligible Account acceptable to the Depositor and Trustee. Notwithstanding the foregoing, one of the Collection Accounts established by WMMSC shall be an Investment Account. Funds deposited in a Collection Account may be drawn on by the applicable Servicer in accordance with Section 3.08. (c) Each Servicer shall deposit in the applicable Collection Account on a daily basis, unless otherwise indicated, and retain therein, the following collections remitted by Subservicers or payments received by such Servicer and payments made by such Servicer subsequent to the Cut-off Date, other than payments of principal and interest due on or before the Cut-off Date: (i) all payments on account of principal on the related Mortgage Loans, including all Principal Prepayments; (ii) all payments on account of interest on the related Mortgage Loans adjusted to the per annum rate equal to the Mortgage Rate reduced by the related Servicing Fee Rate; (iii) all Liquidation Proceeds on the related Mortgage Loans; (iv) all Insurance Proceeds on the related Mortgage Loans including amounts required to be deposited pursuant to Section 3.09 (other than proceeds to be held in the Escrow Account and applied to the restoration or repair of the Mortgaged Property or released to the Mortgagor in accordance with Section 3.09); (v) all Advances made by such Servicer pursuant to Section 5.01; (vi) no later than the withdrawal from the Collection Account pursuant to Section 3.08(a)(viii) each month, the applicable amount of Compensating Interest for such Servicer for the related Prepayment Period. The aggregate of such deposits shall be made from such Servicer's own funds, without reimbursement therefor, up to a maximum amount per month equal to the Compensating Interest Payment, if any, for the Mortgage Loans serviced by that Servicer and Distribution Date. (vii) any amounts required to be deposited by such Servicer in respect of net monthly income from REO Property pursuant to Section 3.11; and (viii) any other amounts required to be deposited hereunder. The foregoing requirements for deposit into each Collection Account shall be exclusive, it being understood and agreed that, without limiting the generality of the foregoing, Ancillary Income need not be deposited by such Servicer into such Collection Account. In 54 addition, notwithstanding the provisions of this Section 3.05, each Servicer may deduct from amounts received by it, prior to deposit to the applicable Collection Account, any portion of any Scheduled Payment representing the applicable Servicing Fee. In the event that a Servicer shall remit any amount not required to be remitted, it may at any time withdraw or direct the institution maintaining the related Collection Account to withdraw such amount from such Collection Account, any provision herein to the contrary notwithstanding. Such withdrawal or direction may be accomplished by delivering written notice thereof to the Trustee or such other institution maintaining such Collection Account which describes the amounts deposited in error in such Collection Account. Each Servicer shall maintain adequate records with respect to all withdrawals made by it pursuant to this Section. All funds deposited in a Collection Account shall be held in trust for the Certificateholders until withdrawn in accordance with Section 3.08(a). (d) On or prior to the Closing Date, the Trustee shall establish and maintain, on behalf of the Certificateholders, the Certificate Account. The Trustee shall, promptly upon receipt, deposit in the Certificate Account and retain therein the following: (i) the aggregate amount remitted by the Servicers to the Trustee pursuant to Section 3.08(a)(viii); (ii) any amount deposited by the Trustee pursuant to Section 3.05(e) in connection with any losses on Eligible Investments; and (iii) any other amounts deposited hereunder which are required to be deposited in the Certificate Account. In the event that a Servicer shall remit to the Trustee any amount not required to be remitted, it may at any time direct the Trustee to withdraw such amount from the Certificate Account, any provision herein to the contrary notwithstanding. Such direction may be accomplished by delivering an Officer's Certificate to the Trustee which describes the amounts deposited in error in the Certificate Account. All funds deposited in the Certificate Account shall be held by the Trustee in trust for the Certificateholders until disbursed in accordance with this Agreement or withdrawn in accordance with Section 3.08(b). In no event shall the Trustee incur liability for withdrawals from the Certificate Account at the direction of a Servicer. (e) Each institution at which a Collection Account or the Certificate Account is maintained shall either hold such funds on deposit uninvested or shall invest the funds therein as directed in writing by the related Servicer or the Trustee, respectively, in Eligible Investments, which shall mature not later than (i) in the case of a Collection Account, the Servicer Remittance Date and (ii) in the case of the Certificate Account, the Business Day immediately preceding the Distribution Date and, in each case, shall not be sold or disposed of prior to its maturity. All income and gain net of any losses realized from any such balances or investment of funds on deposit in a Collection Account shall be for the benefit of the related Servicer as servicing compensation and shall be remitted to it monthly as provided herein. The amount of any realized losses in a Collection Account incurred in any such account in respect of any such investments shall promptly be deposited by the related Servicer in the related Collection Account. The Trustee in its fiduciary capacity shall not be liable for the amount of any loss incurred in respect 55 of any investment or lack of investment of funds held in a Collection Account and made in accordance with this Section 3.05. All income and gain net of any losses realized from any such investment of funds on deposit in the Certificate Account shall be for the benefit of the Trustee as compensation and shall be remitted to it monthly as provided herein. The amount of any realized losses in the Certificate Account incurred in any such account in respect of any such investments shall promptly be deposited by the Trustee in the Certificate Account. (f) Each Servicer shall give notice to the Trustee, each related Seller, each Rating Agency, and the Depositor of any proposed change of the location of the related Collection Account prior to any change thereof. The Trustee shall give notice to each Servicer, each Seller, each Rating Agency and the Depositor of any proposed change of the location of the Certificate Account prior to any change thereof. SECTION 3.06 Establishment of and Deposits to Escrow Accounts; Permitted Withdrawals from Escrow Accounts; Payments of Taxes, Insurance and Other Charges. (a) To the extent required by the related Mortgage Note and not violative of applicable law, the applicable Servicer shall segregate and hold all funds collected and received pursuant to a Mortgage Loan constituting Escrow Payments separate and apart from any of its own funds and general assets and shall establish and maintain one or more Escrow Accounts, in the form of time deposit or demand accounts, titled, "[Servicer's Name] in trust for Credit Suisse First Boston Mortgage Securities Corp., Mortgage-Backed Pass-Through Certificates, Series 2001-AR19", or, if established and maintained by a Subservicer on behalf of a Servicer, "[Subservicer's name], in trust for [Servicer's name]" or "[Subservicer's name], as agent, trustee and/or bailee of taxes and insurance custodial account for [Servicer's name], its successors and assigns, for various owners of interest in [Servicer's name] mortgage-backed pools. The Escrow Accounts shall be Eligible Accounts. Funds deposited in the Escrow Account may be drawn on by the related Servicer in accordance with Section 3.06(d). Except with respect to WMMSC, the creation of any Escrow Account shall be evidenced by a certification in the form of Exhibit P-1 hereto, in the case of an account established with a Servicer, or by a letter agreement in the form of Exhibit P-2 hereto, in the case of an account held by a depository other than a Servicer. A copy of such certification shall be furnished to the Depositor and Trustee. (b) Each Servicer shall deposit in its Escrow Account or Accounts on a daily basis within one Business Day of receipt and retain therein: (i) all Escrow Payments collected on account of the related Mortgage Loans, for the purpose of effecting timely payment of any such items as required under the terms of this Agreement; and (ii) all amounts representing Insurance Proceeds which are to be applied to the restoration or repair of any Mortgaged Property. (c) Each Servicer shall make withdrawals from the Escrow Account only to effect such payments as are required under this Agreement, as set forth in Section 3.06(d). Each Servicer shall be entitled to retain any interest paid on funds deposited in the related Escrow 56 Account by the depository institution, other than interest on escrowed funds required by law to be paid to the Mortgagor. To the extent required by law, the applicable Servicer shall pay interest on escrowed funds to the Mortgagor notwithstanding that the Escrow Account may be non-interest bearing or that interest paid thereon is insufficient for such purposes. (d) Withdrawals from the Escrow Account or Accounts may be made by the related Servicer only: (i) to effect timely payments of ground rents, taxes, assessments, water rates, mortgage insurance premiums, condominium charges, fire and hazard insurance premiums or other items constituting Escrow Payments for the related Mortgage; (ii) to reimburse such Servicer for any Servicing Advances made by such Servicer with respect to a related Mortgage Loan, but only from amounts received on the related Mortgage Loan which represent late collections of Escrow Payments thereunder and other charges and expenses recoverable from the Mortgagor in accordance with the terms of the related Mortgage Note thereunder; (iii) to refund to any Mortgagor any funds found to be in excess of the amounts required under the terms of the related Mortgage Loan; (iv) for transfer to the related Collection Account to reduce the principal balance of the related Mortgage Loan in accordance with the terms of the related Mortgage and Mortgage Note; (v) for application to restore or repair of the related Mortgaged Property in accordance with the procedures outlined in Section 3.09(e); (vi) to pay to such Servicer, or any Mortgagor to the extent required by law, any interest paid on the funds deposited in such Escrow Account; and (vii) to clear and terminate such Escrow Account on the termination of this Agreement. (e) With respect to each Mortgage Loan, the applicable Servicer shall maintain accurate records reflecting the status of ground rents and taxes and any other item which may become a lien senior to the lien of the related Mortgage and the status of Primary Insurance Policy premiums, and fire and hazard insurance coverage and shall obtain, from time to time, all bills for the payment of such charges (including renewal premiums) and shall effect or cause to be effected payment thereof prior to the applicable penalty or termination date. SECTION 3.07 Access to Certain Documentation and Information Regarding the Mortgage Loans; Inspections. (a) Each Servicer shall afford the Depositor and the Trustee reasonable access to all records and documentation regarding the Mortgage Loans and all accounts, insurance information and other matters relating to this Agreement, such access being afforded without 57 charge, but only upon reasonable written request and during normal business hours at the office designated by such Servicer. In addition, the Servicer shall provide to the Special Servicer reasonable access to all records and documentation regarding the Mortgage Loans serviced by it that become Special Serviced Mortgage Loans. (b) Each Servicer shall inspect the related Mortgaged Properties as often as deemed necessary by such Servicer in such Servicer's sole discretion, to assure itself that the value of such Mortgaged Property is being preserved. In addition, if any Mortgage Loan is more than 60 days delinquent, the applicable Servicer shall conduct subsequent inspections in accordance with Accepted Servicing Practices or as may be required by the primary mortgage guaranty insurer. Each Servicer shall keep a written or electronic report of each such inspection. SECTION 3.08 Permitted Withdrawals from the Collection Accounts and Certificate Account. (a) Each Servicer may from time to time make withdrawals from the related Collection Account for the following purposes: (i) to pay to such Servicer (to the extent not previously retained by such Servicer) the servicing compensation to which it is entitled pursuant to Section 3.14, and to pay to such Servicer, as additional servicing compensation, earnings on or investment income with respect to funds in or credited to such Collection Account; (ii) to reimburse such Servicer for unreimbursed Advances made by it, such right of reimbursement pursuant to this subclause (ii) being limited to amounts received on the Mortgage Loan(s) in respect of which any such Advance was made (including without limitation, late recoveries of payments, Liquidation Proceeds and Insurance Proceeds to the extent received by such Servicer); (iii) to reimburse such Servicer for any Nonrecoverable Advance previously made or any amount expended pursuant to Section 3.11(a); (iv) to reimburse such Servicer for (A) unreimbursed Servicing Advances, such Servicer's right to reimbursement pursuant to this clause (A) with respect to any Mortgage Loan being limited to amounts received on such Mortgage Loan which represent late payments of principal and/or interest (including, without limitation, Liquidation Proceeds and Insurance Proceeds with respect to such Mortgage Loan) respecting which any such advance was made and (B) for unpaid Servicing Fees as provided in Section 3.11 hereof; (v) to pay to the purchaser, with respect to each Mortgage Loan or property acquired in respect thereof that has been purchased pursuant to Section 2.02, 2.03 or 3.11, all amounts received thereon after the date of such purchase; (vi) to make any payments required to be made pursuant to Section 2.07(g); 58 (vii) to withdraw any amount deposited in such Collection Account and not required to be deposited therein; (viii) on the Servicer Remittance Date, to withdraw an amount equal to the portion of the Interest Remittance Amount and the Principal Remittance Amount applicable to the Mortgage Loans serviced by such Servicer or portion thereof for such Distribution Date and remit such amount to the Trustee for deposit in the Certificate Account; and (ix) to clear and terminate such Collection Account upon termination of this Agreement pursuant to Section 10.01 hereof. Each Servicer shall keep and maintain separate accounting, on a Mortgage Loan by Mortgage Loan basis, for the purpose of justifying any withdrawal from the related Collection Account pursuant to such subclauses (i), (ii), (iv) and (v). Prior to making any withdrawal from a Collection Account pursuant to subclause (iii), the related Servicer shall deliver to the Trustee a certificate of a Servicing Officer indicating the amount of any previous Advance determined by such Servicer to be a Nonrecoverable Advance and identifying the related Mortgage Loans(s), and their respective portions of such Nonrecoverable Advance. (b) The Trustee shall withdraw funds from the Certificate Account for distributions to Certificateholders, and MGIC, in the manner specified in this Agreement (and to withhold from the amounts so withdrawn, the amount of any taxes that it is authorized to withhold pursuant to Section 2.07). In addition, the Trustee may from time to time make withdrawals from the Certificate Account for the following purposes: (i) to pay to itself the Trustee Fee and any investment income earned from balances in the Certificate Account prior to distributions to Certificateholders; (ii) to withdraw and return to the applicable Servicer for deposit to the applicable Collection Account any amount deposited in the Certificate Account and not required to be deposited therein; and (iii) to clear and terminate the Certificate Account upon termination of the Agreement pursuant to Section 10.01 hereof. SECTION 3.09 Maintenance of Hazard Insurance; Mortgage Impairment Insurance and Primary Insurance Policy; Claims; Restoration of Mortgaged Property. (a) Each Servicer shall cause to be maintained for each Mortgage Loan hazard insurance such that all buildings and improvements upon the Mortgaged Property are insured by a generally acceptable insurer rated either: "V" or better in the current Best's Key Rating Guide ("Best's") or acceptable to FNMA or FHLMC against loss by fire, hazards of extended coverage and such other hazards as are customary in the area where the Mortgaged Property is located, in an amount which is at least equal to the lesser of (i) the replacement value of the improvements securing such Mortgage Loan and (ii) the greater of (A) the outstanding principal balance of the 59 Mortgage Loan and (B) an amount such that the proceeds of such policy shall be sufficient to prevent the Mortgagor and/or the mortgagee from becoming a co-insurer. If upon origination of the Mortgage Loan, the related Mortgaged Property was located in an area identified in the Federal Register by the Flood Emergency Management Agency as having special flood hazards (and such flood insurance has been made available), the related Servicer shall cause a flood insurance policy to be maintained with respect to such Mortgage Loan. Such policy shall meet the requirements of the current guidelines of the Federal Insurance Administration and be in an amount representing coverage equal to the lesser of (i) the minimum amount required, under the terms of coverage, to compensate for any damage or loss on a replacement cost basis (or the unpaid principal balance of the mortgage if replacement cost coverage is not available for the type of building insured) and (ii) the maximum amount of insurance which is available under the Flood Disaster Protection Act of 1973, as amended. If a Mortgage is secured by a unit in a condominium project, the related Servicer shall verify that the coverage required of the owner's association, including hazard, flood, liability, and fidelity coverage, is being maintained in accordance with the requirements of the Servicer for mortgage loans that it services on its own account. Each Servicer shall cause to be maintained on each Mortgaged Property such other additional special hazard insurance as may be required pursuant to such applicable laws and regulations as shall at any time be in force and as shall require such additional insurance, or pursuant to the requirements of any Primary Insurance Policy insurer, or as may be required to conform with Accepted Servicing Practices to the extent permitted by the Mortgage Note, the Mortgage or applicable law; provided, however, that the Servicer shall not be required to bear the cost of such insurance. All policies required hereunder shall name the related Servicer as loss payee and shall be endorsed with standard or union mortgagee clauses, without contribution, which shall provide for prior written notice of any cancellation, reduction in amount or material change in coverage. A Servicer shall not interfere with the Mortgagor's freedom of choice at the origination of such Mortgage Loan in selecting either his insurance carrier or agent, provided, however, that such Servicer shall not accept any such insurance policies from insurance companies unless such companies are rated: B:III or better in Best's or acceptable to FNMA or FHLMC and are licensed to do business in the jurisdiction in which the Mortgaged Property is located. The related Servicer shall determine that such policies provide sufficient risk coverage and amounts, that they insure the property owner, and that they properly describe the property address. Pursuant to Section 3.05, any amounts collected by a Servicer under any such policies (other than amounts to be deposited in the related Escrow Account and applied to the restoration or repair of the related Mortgaged Property, or property acquired in liquidation of the Mortgage Loan, or to be released to the Mortgagor, in accordance with such Servicer's normal servicing procedures) shall be deposited in the related Collection Account (subject to withdrawal pursuant to Section 3.08(a)). 60 Any cost incurred by a Servicer in maintaining any such insurance shall not, for the purpose of calculating monthly distributions to the Certificateholders or remittances to the Trustee for their benefit, be added to the principal balance of the Mortgage Loan, notwithstanding that the terms of the Mortgage Loan so permit. Such costs shall constitute a Servicing Advance and will be reimbursable to the Servicer to the extent permitted by Section 3.08 hereof. It is understood and agreed that no earthquake or other additional insurance is to be required of any Mortgagor or maintained on property acquired in respect of a Mortgage other than pursuant to such applicable laws and regulations as shall at any time be in force and as shall require such additional insurance. (b) In the event that a Servicer shall obtain and maintain a blanket policy insuring against losses arising from fire and hazards covered under extended coverage on all of the related Mortgage Loans, then, to the extent such policy provides coverage in an amount equal to the amount required pursuant to Section 3.09(a) and otherwise complies with all other requirements of Section 3.09(a), it shall conclusively be deemed to have satisfied its obligations as set forth in Section 3.09(a). Any amounts collected by a Servicer under any such policy relating to a Mortgage Loan shall be deposited in the related Collection Account subject to withdrawal pursuant to Section 3.08(a). Such policy may contain a deductible clause, in which case, in the event that there shall not have been maintained on the related Mortgaged Property a policy complying with Section 3.09(a), and there shall have been a loss which would have been covered by such policy, the related Servicer shall deposit in the related Collection Account at the time of such loss the amount not otherwise payable under the blanket policy because of such deductible clause, such amount to be deposited from such Servicer's funds, without reimbursement therefor. Upon request of the Trustee, a Servicer shall cause to be delivered to the Trustee a certified true copy of such policy and a statement from the insurer thereunder that such policy shall in no event be terminated or materially modified without 30 days' prior written notice to the Trustee. In connection with its activities as Servicer of the related Mortgage Loans, such Servicer agrees to present, on behalf of itself, the Depositor, and the Trustee for the benefit of the Certificateholders, claims under any such blanket policy. (c) Subject to applicable law, with respect to each Mortgage Loan with a Loan-to-Value Ratio in excess of 80% which the applicable Seller represented to be covered by a Primary Insurance Policy as of the Cut-off Date, the related Servicer shall, without any cost to the Depositor or Trustee, maintain or cause the Mortgagor to maintain in full force and effect a Primary Insurance Policy insuring that portion of the Mortgage Loan in excess of 75% of value, and shall pay or shall cause the Mortgagor to pay, the premium thereon on a timely basis, until the loan-to-value ratio of such Mortgage Loan is reduced to 80%, based on either (i) a current appraisal of the Mortgaged Property or (ii) the appraisal of the Mortgaged Property obtained at the time the Mortgage Loan was originated. In the event that such Primary Insurance Policy shall be terminated, the related Servicer shall obtain from another Qualified Insurer a comparable replacement policy, with a total coverage equal to the remaining coverage of such terminated Primary Insurance Policy. If the insurer shall cease to be a Qualified Insurer, the related Servicer shall determine whether recoveries under the Primary Insurance Policy are jeopardized for reasons related to the financial condition of such insurer, it being understood that such Servicer shall in no event have any responsibility or liability for any failure to recover under the Primary Insurance Policy for such reason. If the related Servicer determines that recoveries are so jeopardized, it shall notify the Mortgagor, if required, and obtain from another Qualified Insurer 61 a replacement insurance policy. The related Servicer shall not take any action which would result in noncoverage under any applicable Primary Insurance Policy of any loss which, but for the actions of such Servicer would have been covered thereunder. In connection with any assumption or substitution agreement entered into or to be entered into pursuant to Section 3.10, each Servicer shall promptly notify the insurer under the related Primary Insurance Policy, if any, of such assumption or substitution of liability in accordance with the terms of such Primary Insurance Policy and shall take all actions which may be required by such insurer as a condition to the continuation of coverage under such Primary Insurance Policy provided that such required actions are in compliance with all applicable law. If such Primary Insurance Policy is terminated as a result of such assumption or substitution of liability, the related Servicer shall obtain a replacement Primary Insurance Policy as provided above; provided that under applicable law and the terms of the related Mortgage Note and Mortgage the cost of such policy may be charged to the successor Mortgagor. With respect to the MGIC Mortgage Loans, the MGIC Policy shall be maintained by the Trustee for the life of such Mortgage Loans, unless otherwise prohibited by law. The applicable Servicer shall submit all claims required to be made under the MGIC Policy in a timely fashion and shall otherwise comply with the terms of the MGIC Policy. Each Servicer shall deposit all amounts received under the MGIC Policy into the Collection Account. The MGIC Fee shall be paid by the Trustee from amounts withdrawn from the Certificate Account in accordance with Section 4.01. With respect to Mortgage Loans which are not MGIC Mortgage Loans, the applicable Servicer agrees to effect timely payment of the premiums on each Primary Insurance Policy, and such payments shall constitute Servicing Advances reimbursable to such Servicer pursuant to Section 3.08. (d) In connection with its activities as servicer, each Servicer agrees to prepare and present, on behalf of itself, the Depositor, the Trustee and the Certificateholders, claims to the insurer under any Primary Insurance Policy in a timely fashion in accordance with the terms of such Primary Insurance Policy and, in this regard, to take such reasonable action as shall be necessary to permit recovery under any Primary Insurance Policy respecting defaulted Mortgage Loans. Pursuant to Section 3.05, any amounts collected by a Servicer under any Primary Insurance Policy shall be deposited in the related Collection Account, subject to withdrawal pursuant to Section 3.08. (e) A Servicer need not obtain the approval of the Trustee prior to releasing any Insurance Proceeds to the Mortgagor to be applied to the restoration or repair of the Mortgaged Property if such release is in accordance with Accepted Servicing Practices. At a minimum, each Servicer shall comply with the following conditions in connection with any such release of Insurance Proceeds: (i) such Servicer shall receive satisfactory independent verification of completion of repairs and issuance of any required approvals with respect thereto; 62 (ii) such Servicer shall take all steps necessary to preserve the priority of the lien of the Mortgage, including, but not limited to requiring waivers with respect to mechanics' and materialmen's liens; and (iii) pending repairs or restoration, such Servicer shall place the Insurance Proceeds in the related Escrow Account. (f) If the Trustee is named as an additional loss payee, the related Servicer is hereby empowered to endorse any loss draft issued in respect of such a claim in the name of the Trustee. SECTION 3.10 Enforcement of Due-on-Sale Clauses; Assumption Agreements. (a) Each Servicer shall use its best efforts to enforce any "due-on-sale" provision contained in any related Mortgage or Mortgage Note and to deny assumption by the person to whom the Mortgaged Property has been or is about to be sold whether by absolute conveyance or by contract of sale, and whether or not the Mortgagor remains liable on the Mortgage and the Mortgage Note. When the Mortgaged Property has been conveyed by the Mortgagor, the related Servicer shall, to the extent it has knowledge of such conveyance, exercise its rights to accelerate the maturity of such Mortgage Loan under the "due-on-sale" clause applicable thereto, provided, however, that such Servicer shall not exercise such rights if prohibited by law from doing so or if the exercise of such rights would impair or threaten to impair any recovery under the related Primary Insurance Policy, if any. (b) If a Servicer reasonably believes it is unable under applicable law to enforce such "due-on-sale" clause, such Servicer shall enter into (i) an assumption and modification agreement with the person to whom such property has been conveyed, pursuant to which such person becomes liable under the Mortgage Note and the original Mortgagor remains liable thereon or (ii) in the event such Servicer is unable under applicable law to require that the original Mortgagor remain liable under the Mortgage Note, a substitution of liability agreement with the purchaser of the Mortgaged Property pursuant to which the original Mortgagor is released from liability and the purchaser of the Mortgaged Property is substituted as Mortgagor and becomes liable under the Mortgage Note. Notwithstanding the foregoing, a Servicer shall not be deemed to be in default under this Section by reason of any transfer or assumption which such Servicer reasonably believes it is restricted by law from preventing, for any reason whatsoever. In connection with any such assumption, no material term of the Mortgage Note, including without limitation, the Mortgage Rate borne by the related Mortgage Note, the term of the Mortgage Loan or the outstanding principal amount of the Mortgage Loan shall be changed. (c) To the extent that any Mortgage Loan is assumable, the related Servicer shall inquire diligently into the creditworthiness of the proposed transferee, and shall use the underwriting criteria for approving the credit of the proposed transferee which are used by FNMA with respect to underwriting mortgage loans of the same type as the Mortgage Loans. If the credit of the proposed transferee does not meet such underwriting criteria, the related Servicer diligently shall, to the extent permitted by the Mortgage or the Mortgage Note and by applicable law, accelerate the maturity of the Mortgage Loan. 63 (d) Subject to each Servicer's duty to enforce any due-on-sale clause to the extent set forth in this Section 3.10, in any case in which a Mortgaged Property has been conveyed to a Person by a Mortgagor, and such Person is to enter into an assumption agreement or modification agreement or supplement to the Mortgage Note or Mortgage that requires the signature of the Trustee, or if an instrument of release signed by the Trustee is required releasing the Mortgagor from liability on the Mortgage Loan, such Servicer shall prepare and deliver or cause to be prepared and delivered to the Trustee for signature and shall direct, in writing, the Trustee to execute the assumption agreement with the Person to whom the Mortgaged Property is to be conveyed and such modification agreement or supplement to the Mortgage Note or Mortgage or other instruments as are reasonable or necessary to carry out the terms of the Mortgage Note or Mortgage or otherwise to comply with any applicable laws regarding assumptions or the transfer of the Mortgaged Property to such Person. In connection with any such assumption, no material term of the Mortgage Note may be changed. Together with each such substitution, assumption or other agreement or instrument delivered to the Trustee for execution by it, the related Servicer shall deliver an Officer's Certificate signed by a Servicing Officer stating that the requirements of this subsection have been met in connection therewith. The related Servicer shall notify the Trustee that any such substitution or assumption agreement has been completed by forwarding to the Trustee the original of such substitution or assumption agreement, which in the case of the original shall be added to the related Mortgage File and shall, for all purposes, be considered a part of such Mortgage File to the same extent as all other documents and instruments constituting a part thereof. Any fee collected by a Servicer for entering into an assumption or substitution of liability agreement will be retained by such Servicer as additional servicing compensation. SECTION 3.11 Realization Upon Defaulted Mortgage Loans; Repurchase of Certain Mortgage Loans. (a) Each Servicer shall use reasonable efforts to foreclose upon or otherwise comparably convert the ownership of properties securing such of the related Mortgage Loans as come into and continue in default and as to which no satisfactory arrangements can be made for collection of delinquent payments. In connection with such foreclosure or other conversion, each Servicer shall take such action as (i) such Servicer would take under similar circumstances with respect to a similar mortgage loan held for its own account for investment, (ii) shall be consistent with Accepted Servicing Practices, (iii) such Servicer shall determine consistently with Accepted Servicing Practices to be in the best interest of the Trustee and Certificateholders, and (iv) is consistent with the requirements of the insurer under any Required Insurance Policy; provided, however, that such Servicer shall not be required to expend its own funds in connection with any foreclosure or towards the restoration of any property unless it shall determine (i) that such restoration and/or foreclosure will increase the proceeds of liquidation of the related Mortgage Loan after reimbursement to itself of such expenses and (ii) that such expenses will be recoverable to it through Liquidation Proceeds (respecting which it shall have priority for purposes of withdrawals from the related Collection Account). The related Servicer shall be responsible for all other costs and expenses incurred by it in any such proceedings; provided, however, that it shall be entitled to reimbursement thereof from the Liquidation Proceeds with respect to the related Mortgaged Property, as provided in the definition of Liquidation Proceeds and as provided in Section 3.08(a)(iv)(A). 64 Notwithstanding anything to the contrary contained in this Agreement, in connection with a foreclosure or acceptance of a deed in lieu of foreclosure, in the event the related Servicer has reasonable cause to believe that a Mortgaged Property is contaminated by hazardous or toxic substances or wastes, or if the Trustee otherwise requests, an environmental inspection or review of such Mortgaged Property conducted by a qualified inspector shall be arranged for by such Servicer. Upon completion of the inspection, the related Servicer shall promptly provide the Trustee with a written report of environmental inspection. In the event the environmental inspection report indicates that the Mortgaged Property is contaminated by hazardous or toxic substances or wastes, the related Servicer shall not proceed with foreclosure or acceptance of a deed in lieu of foreclosure if the estimated costs of the environmental clean up, as estimated in the environmental inspection report, together with the Servicing Advances and Advances made by such Servicer and the estimated costs of foreclosure or acceptance of a deed in lieu of foreclosure exceeds the estimated value of the Mortgaged Property. If however, the aggregate of such clean up and foreclosure costs, Advances and Servicing Advances are less than or equal to the estimated value of the Mortgaged Property, then the related Servicer may, in its reasonable judgment and in accordance with Accepted Servicing Practices, choose to proceed with foreclosure or acceptance of a deed in lieu of foreclosure and such Servicer shall be reimbursed for all reasonable costs associated with such foreclosure or acceptance of a deed in lieu of foreclosure and any related environmental clean up costs, as applicable, from the related Liquidation Proceeds, or if the Liquidation Proceeds are insufficient to fully reimburse such Servicer, such Servicer shall be entitled to be reimbursed from amounts in the related Collection Account pursuant to Section 3.08(a) hereof. In the event the related Servicer does not proceed with foreclosure or acceptance of a deed in lieu of foreclosure pursuant to the first sentence of this paragraph, such Servicer shall be reimbursed for all Advances and Servicing Advances made with respect to the related Mortgaged Property from the related Collection Account pursuant to Section 3.08(a) hereof, and such Servicer shall have no further obligation to service such Mortgage Loan under the provisions of this Agreement. (b) With respect to any REO Property, the deed or certificate of sale shall be taken in the name of the Trustee for the benefit of the Certificateholders, or its nominee, on behalf of the Certificateholders. If the deed or certificate of sale is taken in the name of the Trustee, the Trustee's name shall be placed on the title to such REO Property solely as the Trustee hereunder and not in its individual capacity. The related Servicer shall ensure that the title to such REO Property references this Agreement and the Trustee's capacity hereunder. Pursuant to its efforts to sell such REO Property, the related Servicer shall in accordance with Accepted Servicing Practices manage, conserve, protect and operate each REO Property for the purpose of its prompt disposition and sale. The related Servicer, either itself or through an agent selected by such Servicer, shall manage, conserve, protect and operate the REO Property in the same manner that it manages, conserves, protects and operates other foreclosed property for its own account, and in the same manner that similar property in the same locality as the REO Property is managed. Upon request, the related Servicer shall furnish to the Trustee on or before each Distribution Date a statement with respect to any REO Property covering the operation of such REO Property for the previous calendar month and such Servicer's efforts in connection with the sale of such REO Property and any rental of such REO Property incidental to the sale thereof for the previous calendar month. That statement shall be accompanied by such other information as the Trustee shall reasonably request and which is necessary to enable the Trustee 65 to comply with the reporting requirements of the REMIC Provisions. The net monthly rental income, if any, from such REO Property shall be deposited in the related Collection Account no later than the close of business on each Determination Date. The related Servicer shall perform the tax reporting and withholding required by Sections 1445 and 6050J of the Code with respect to foreclosures and abandonments, the tax reporting required by Section 6050H of the Code with respect to the receipt of mortgage interest from individuals and any tax reporting required by Section 6050P of the Code with respect to the cancellation of indebtedness by certain financial entities, by preparing such tax and information returns as may be required, in the form required, and delivering the same to the Trustee for filing. To the extent consistent with Accepted Servicing Practices, the related Servicer shall also maintain on each REO Property fire and hazard insurance with extended coverage in an amount which is equal to the outstanding principal balance of the related Mortgage Loan (as reduced by any amount applied as a reduction of principal at the time of acquisition of the REO Property), liability insurance and, to the extent required and available under the Flood Disaster Protection Act of 1973, as amended, flood insurance in the amount required above. (c) In the event that the Trust Fund acquires any Mortgaged Property as aforesaid or otherwise in connection with a default or imminent default on a Mortgage Loan, the related Servicer shall dispose of such Mortgaged Property prior to three years after the end of the calendar year of its acquisition by the Trust Fund unless (i) the Trustee shall have been supplied with an Opinion of Counsel to the effect that the holding by the Trust Fund of such Mortgaged Property subsequent to such three-year period will not result in the imposition of taxes on "prohibited transactions" of the REMIC hereunder as defined in section 860F of the Code or cause the REMIC hereunder to fail to qualify as a REMIC at any time that any Certificates are outstanding, in which case the Trust Fund may continue to hold such Mortgaged Property (subject to any conditions contained in such Opinion of Counsel) or (ii) the applicable Servicer shall have applied for, prior to the expiration of such three-year period, an extension of such three-year period in the manner contemplated by Section 856(e)(3) of the Code, in which case the three-year period shall be extended by the applicable extension period. Notwithstanding any other provision of this Agreement, no Mortgaged Property acquired by the Trust Fund shall be rented (or allowed to continue to be rented) or otherwise used for the production of income by or on behalf of the Trust Fund in such a manner or pursuant to any terms that would (i) cause such Mortgaged Property to fail to qualify as "foreclosure property" within the meaning of section 860G(a)(8) of the Code or (ii) subject the REMIC hereunder to the imposition of any federal, state or local income taxes on the income earned from such Mortgaged Property under Section 860G(c) of the Code or otherwise, unless the related Servicer has agreed to indemnify and hold harmless the Trust Fund with respect to the imposition of any such taxes. In the event of a default on a Mortgage Loan one or more of whose obligor is not a United States Person, as that term is defined in Section 7701(a)(30) of the Code, in connection with any foreclosure or acquisition of a deed in lieu of foreclosure (together, "foreclosure") in respect of such Mortgage Loan, the related Servicer will cause compliance with the provisions of Treasury Regulation Section 1.1445-2(d)(3) (or any successor thereto) necessary to assure that no withholding tax obligation arises with respect to the proceeds of such foreclosure except to the extent, if any, that proceeds of such foreclosure are required to be remitted to the obligors on such Mortgage Loan. 66 (d) The decision of a Servicer to foreclose on a defaulted Mortgage Loan shall be subject to a determination by such Servicer that the proceeds of such foreclosure would exceed the costs and expenses of bringing such a proceeding. The income earned from the management of any REO Properties, net of reimbursement to such Servicer for all expenses incurred (including but not limited to any property or other taxes) in connection with such management and net of applicable accrued and unpaid Servicing Fees, and unreimbursed Advances and Servicing Advances, shall be applied to the payment of principal of and interest on the related defaulted Mortgage Loans (with interest accruing as though such Mortgage Loans were still current) and all such income shall be deemed, for all purposes in this Agreement, to be payments on account of principal and interest on the related Mortgage Notes and shall be deposited into the related Collection Account. To the extent the net income received during any calendar month is in excess of the amount attributable to amortizing principal and accrued interest at the related Mortgage Rate on the related Mortgage Loan for such calendar month, such excess shall be considered to be a partial prepayment of principal of the related Mortgage Loan. (e) The proceeds from any liquidation of a Mortgage Loan, as well as any income from an REO Property, will be applied in the following order of priority: first, to reimburse the related Servicer for any related unreimbursed Servicing Advances and Servicing Fees; second, to reimburse such Servicer for any unreimbursed Advances; third, to reimburse the related Collection Account for any Nonrecoverable Advances (or portions thereof) that were previously withdrawn by such Servicer pursuant to Section 3.08(a)(iii) that related to such Mortgage Loan; fourth, to accrued and unpaid interest (to the extent no Advance has been made for such amount or any such Advance has been reimbursed) on the Mortgage Loan or related REO Property, at the per annum rate equal to the related Mortgage Rate reduced by the related Servicing Fee Rate and the MGIC Fee Rate, if applicable, to the Due Date occurring in the month in which such amounts are required to be distributed; and fifth, as a recovery of principal of the Mortgage Loan. Excess Proceeds, if any, from the liquidation of a Liquidated Mortgage Loan will be retained by the related Servicer as additional servicing compensation pursuant to Section 3.14. (f) Each Servicer of the Mortgage Loans may (but is not obligated to) enter into a special servicing agreement with an unaffiliated holder of a 100% Percentage Interest of the most junior class of Subordinate Certificates, subject to each Rating Agency's acknowledgment that the Ratings of the Certificates in effect immediately prior to the entering into such agreement would not be qualified, downgraded or withdrawn and the Certificates would not be placed on credit review status (except for possible upgrading) as a result of such agreement. Any such agreement may contain provisions whereby such Holder may (i) instruct the related Servicer to commence or delay foreclosure proceedings with respect to delinquent Mortgage Loans and will contain provisions for the deposit of cash with such Servicer by the Holder that would be available for distribution to Certificateholders if Liquidation Proceeds are less than they otherwise may have been had such Servicer acted in accordance with its normal procedures, (ii) purchase delinquent Mortgage Loans from the Trust Fund immediately prior to the commencement of foreclosure proceedings at a price equal to the aggregate outstanding Principal Balance of such Mortgage Loans plus accrued interest thereon at the applicable Mortgage Rate through the last day of the month in which such Mortgage Loan is purchased, and/or (iii) assume all of the servicing rights and obligations with respect to delinquent Mortgage Loans so long as such Holder (A) meets the requirements for a Subservicer set forth in Section 3.02(a), and (B) will service such Mortgage Loans in accordance with this Agreement. 67 (g) Vesta, at its option, may (but is not obligated to) purchase from the Trust Fund, (a) any Mortgage Loan that is delinquent in payment 90 or more days or (b) any related Mortgage Loan with respect to which there has been initiated legal action or other proceedings for the foreclosure of the related Mortgaged Property either judicially or non-judicially. Any such purchase shall be made by Vesta with its own funds at a price equal to the Purchase Price for such Mortgage Loan. SECTION 3.12 Trustee to Cooperate; Release of Mortgage Files. Upon the payment in full of any Mortgage Loan, or the receipt by a Servicer of a notification that payment in full will be escrowed in a manner customary for such purposes, such Servicer will immediately notify the Trustee or the Custodian on its behalf by delivering, or causing to be delivered a "Request for Release" substantially in the form of Exhibit K. Upon receipt of such request, the Trustee shall within three Business Days release the related Mortgage File to the related Servicer, and the Trustee shall within three Business Days of such Servicer's direction execute and deliver to such Servicer the request for reconveyance, deed of reconveyance or release or satisfaction of mortgage or such instrument releasing the lien of the Mortgage in each case provided by such Servicer, together with the Mortgage Note with written evidence of cancellation thereon. Expenses incurred in connection with any instrument of satisfaction or deed of reconveyance shall be chargeable to the related Mortgagor. From time to time and as shall be appropriate for the servicing or foreclosure of any Mortgage Loan, including for such purpose, collection under any policy of flood insurance, any fidelity bond or errors or omissions policy, or for the purposes of effecting a partial release of any Mortgaged Property from the lien of the Mortgage or the making of any corrections to the Mortgage Note or the Mortgage or any of the other documents included in the Mortgage File, the Trustee or the Custodian on its behalf shall, within three Business Days of delivery to the Trustee of a Request for Release in the form of Exhibit K signed by a Servicing Officer, release the Mortgage File to the related Servicer. Subject to the further limitations set forth below, the related Servicer shall cause the Mortgage File or documents so released to be returned to the Trustee or the Custodian on its behalf when the need therefor by such Servicer no longer exists, unless the Mortgage Loan is liquidated and the proceeds thereof are deposited in the related Collection Account, in which case such Servicer shall deliver to the Trustee a Request for Release in the form of Exhibit K, signed by a Servicing Officer. If a Servicer at any time seeks to initiate a foreclosure proceeding in respect of any Mortgaged Property as authorized by this Agreement, such Servicer shall deliver or cause to be delivered to the Trustee or the Custodian on its behalf, for signature, as appropriate, any court pleadings, requests for trustee's sale or other documents necessary to effectuate such foreclosure or any legal action brought to obtain judgment against the Mortgagor on the Mortgage Note or the Mortgage or to obtain a deficiency judgment or to enforce any other remedies or rights provided by the Mortgage Note or the Mortgage or otherwise available at law or in equity. SECTION 3.13 Documents, Records and Funds in Possession of a Servicer to be Held for the Trustee. Notwithstanding any other provisions of this Agreement, each Servicer shall transmit to the Trustee as required by this Agreement all documents and instruments in respect of 68 a Mortgage Loan coming into the possession of the related Servicer from time to time required to be delivered to the Trustee pursuant to the terms hereof and shall account fully to the Trustee for any funds received by such Servicer or which otherwise are collected by such Servicer as Liquidation Proceeds or Insurance Proceeds in respect of any Mortgage Loan. All Mortgage Files and funds collected or held by, or under the control of, a Servicer in respect of any Mortgage Loans, whether from the collection of principal and interest payments or from Liquidation Proceeds, including but not limited to, any funds on deposit in a Collection Account, shall be held by the related Servicer for and on behalf of the Trustee and shall be and remain the sole and exclusive property of the Trustee, subject to the applicable provisions of this Agreement. Each Servicer also agrees that it shall not create, incur or subject any Mortgage File or any funds that are deposited in the related Collection Account, Certificate Account or any related Escrow Account, or any funds that otherwise are or may become due or payable to the Trustee for the benefit of the Certificateholders, to any claim, lien, security interest, judgment, levy, writ of attachment or other encumbrance, or assert by legal action or otherwise any claim or right of setoff against any Mortgage File or any funds collected on, or in connection with, a Mortgage Loan, except, however, that such Servicer shall be entitled to set off against and deduct from any such funds any amounts that are properly due and payable to such Servicer under this Agreement. SECTION 3.14 Servicing Fee. (a) As compensation for its services hereunder, each Servicer shall be entitled to withdraw from the applicable Collection Account or to retain from interest payments on the related Mortgage Loans the amount of its Servicing Fee for each Mortgage Loan serviced by it, less any amounts in respect of its Servicing Fee payable by such Servicer pursuant to Section 3.05(c)(vi). The Servicing Fee is limited to, and payable solely from, the interest portion of such Scheduled Payments collected by the related Servicer or as otherwise provided in Section 3.08(a). In connection with the servicing of any Special Serviced Mortgage Loan, the Special Servicer shall receive the Servicing Fee for each such Mortgage Loan as its compensation. (b) Additional servicing compensation in the form of Ancillary Income shall be retained by the related Servicer. Each Servicer shall be required to pay all expenses incurred by it in connection with its servicing activities hereunder (including the payment of any expenses incurred in connection with any Subservicing Agreement entered into pursuant to Section 3.02 and the payment of any premiums for insurance required pursuant to Section 3.18) and shall not be entitled to reimbursement thereof except as specifically provided for in this Agreement. SECTION 3.15 Access to Certain Documentation. Each Servicer shall provide to the OTS and the FDIC and to comparable regulatory authorities supervising Holders of Subordinate Certificates and the examiners and supervisory agents of the OTS, the FDIC and such other authorities, access to the documentation regarding the related Mortgage Loans required by applicable regulations of the OTS and the FDIC. Such access shall be afforded without charge, but only upon reasonable and prior written request and during normal business hours at the offices designated by such Servicer. Nothing in this Section shall limit the obligation of any Servicer to observe any applicable law prohibiting 69 disclosure of information regarding the Mortgagors and the failure of such Servicer to provide access as provided in this Section as a result of such obligation shall not constitute a breach of this Section. Nothing in this Section 3.15 shall require any Servicer to collect, create, collate or otherwise generate any information that it does not generate in its usual course of business. SECTION 3.16 Annual Statement as to Compliance. Each Servicer shall deliver to the Depositor, the Rating Agencies, and the Trustee on or before 120 days after the end of such Servicer's fiscal year, commencing in its 2002 fiscal year, an Officer's Certificate stating, as to the signer thereof, that (i) a review of the activities of such Servicer during the preceding calendar year and of the performance of such Servicer under this Agreement has been made under such officer's supervision, and (ii) to the best of such officer's knowledge, based on such review, such Servicer has fulfilled all 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 and the action being taken by such Servicer to cure such default. SECTION 3.17 Annual Independent Public Accountants' Servicing Statement; Financial Statements. On or before 120 days after the end of each Servicer's fiscal year, commencing in its 2002 fiscal year, each Servicer at its expense shall cause a nationally or regionally recognized firm of independent public accountants (who may also render other services to such Servicer, any Seller or any affiliate thereof) which is a member of the American Institute of Certified Public Accountants to furnish a statement to the Trustee, and the Depositor to the effect that (i) with respect to each Servicer other than WMMSC, such firm has examined certain documents and records relating to the servicing of mortgage loans which such Servicer is servicing, including the related Mortgage Loans, and that, on the basis of such examination, conducted substantially in compliance with the Uniform Single Attestation Program for Mortgage Bankers or the Audit Guide for HUD Approved Title II Approved Mortgagees and Loan Correspondent Programs, nothing has come to their attention which would indicate that such servicing has not been conducted in compliance with Accepted Servicing Practices, except for (a) such exceptions as such firm shall believe to be immaterial, and (b) such other exceptions as shall be set forth in such statement and (ii) with respect to WMMSC as servicer of the WMMSC Serviced Loans, in connection with the firm's examination of the financial statements as of the previous December 31 of WMMSC's parent corporation (which shall include a limited examination of WMMSC's financial statements), nothing came to their attention that indicated that WMMSC was not in compliance with the terms of this Agreement, except for (a) such exceptions as such firm believes to be immaterial, and (b) such other exceptions as are set forth in such statement. In rendering such statement, such firm may rely, as to matters relating to direct servicing of mortgage loans by Subservicers, upon comparable statements for examinations conducted substantially in compliance with the Uniform Single Attestation Program for Mortgage Bankers or the Audit Guide for HUD Approved Title II Approved Mortgagees and Loan Correspondent Programs (rendered within one year of such statement) of independent public accountants with respect to the related Subservicer. Copies of such statement shall be provided by the Trustee to any Certificateholder upon request at the related Servicer's expense, provided such statement is delivered by such Servicer to the Trustee. 70 SECTION 3.18 Maintenance of Fidelity Bond and Errors and Omissions Insurance. Each Servicer shall maintain with responsible companies, at its own expense, a blanket Fidelity Bond and an Errors and Omissions Insurance Policy, with broad coverage on all officers, employees or other persons acting in any capacity requiring such persons to handle funds, money, documents or papers relating to the related Mortgage Loans ("Servicer Employees"). Any such Fidelity Bond and Errors and Omissions Insurance Policy shall be in the form of the Mortgage Banker's Blanket Bond and shall protect and insure the related Servicer against losses, including forgery, theft, embezzlement, fraud, errors and omissions and negligent acts of such Servicer Employees. Such Fidelity Bond and Errors and Omissions Insurance Policy also shall protect and insure each Servicer against losses in connection with the release or satisfaction of a related Mortgage Loan without having obtained payment in full of the indebtedness secured thereby. No provision of this Section 3.18 requiring such Fidelity Bond and Errors and Omissions Insurance Policy shall diminish or relieve a Servicer from its duties and obligations as set forth in this Agreement. The minimum coverage under any such bond and insurance policy shall be at least equal to the corresponding amounts required by FNMA. Upon the request of the Trustee, the related Servicer shall cause to be delivered to the Trustee a certificate of insurance of the insurer and the surety including a statement from the surety and the insurer that such fidelity bond and insurance policy shall in no event be terminated or materially modified without 30 days' prior written notice to the Trustee. SECTION 3.19 Special Serviced Mortgage Loans. If directed by the Special Servicer and solely at the Special Servicer's option, a Servicer, other than ABN AMRO or WMMSC, shall transfer the servicing of any Mortgage Loan 90 days or more delinquent to the Special Servicer. The Special Servicer shall thereupon assume all of the rights and obligations of such Servicer hereunder arising thereafter and the predecessor servicer shall have no further responsibility with respect to such Mortgage Loan (except that the Special Servicer shall not be (i) liable for losses of such Servicer pursuant to Section 3.09 hereof or for any acts or omissions of the related predecessor Servicer hereunder prior to the servicing transfer date, (ii) obligated to effectuate repurchases or substitutions of Mortgage Loans hereunder including, but not limited to, repurchases or substitutions of Mortgage Loans pursuant to Section 2.02 or 2.03 hereof or (iii) deemed to have made any representations and warranties of such predecessor Servicer hereunder). Upon the transfer of the servicing of any such Mortgage Loan to the Special Servicer, the Special Servicer shall be entitled to the Servicing Fee and other compensation accruing after the servicing transfer date with respect to such Mortgage Loans pursuant to Section 3.14. In connection with the transfer of the servicing of any Mortgage Loan to the Special Servicer, the applicable Servicer shall, at such Servicer's expense, deliver to the Special Servicer all documents and records relating to such Mortgage Loans and an accounting of amounts collected or held by it and otherwise use its best efforts to effect the orderly and efficient transfer of the servicing to the Special Servicer. On the servicing transfer date, the Special Servicer shall reimburse the predecessor servicer for all unreimbursed Advances, Servicing Advances and Servicing Fees relating to the Mortgage Loans for which the servicing is being transferred. The Special Servicer shall be entitled to be reimbursed for all such Advances, 71 Servicing Advances and Servicing Fees paid by the Special Servicer to the predecessor servicer pursuant to Section 3.08. In addition, the Special Servicer shall amend the Mortgage Loan Schedule to reflect that such Mortgage Loans are Special Serviced Mortgage Loans. 72 ARTICLE IV PAYMENTS AND STATEMENTS TO CERTIFICATEHOLDERS SECTION 4.01 Priorities of Distribution.

SECTION 4.02 Allocation of Losses. (a) Realized Losses on the Mortgage Loans in each of Loan Group I, Loan Group II, Loan Group III and Loan Group IV with respect to any Distribution Date shall be determined by the Trustee and allocated by the Trustee to the Classes of Certificates as follows: (i) any Realized Loss shall be allocated first, to the Group C-B Certificates in decreasing order of their numerical Class designations (beginning with the Class C-B-6 Certificates), until the respective Class Principal Balance of each such Class is reduced to zero, and second, to the Senior Certificates of such Certificate Group, pro rata, on the basis of their respective Class Principal Balances; provided, however, such losses on Loan Group I, Loan Group II, Loan Group III and Loan Group IV will only be allocated to the related Senior Certificates for such Loan Group; and (ii) On each Distribution Date, Excess Losses and Extraordinary Losses for Mortgage Loans in Loan Group I, Loan Group II, Loan Group III and Loan Group IV will be allocated pro rata among all Classes of Senior Certificates and the Subordinate Certificates, in each case, relating to Loan Group I, Loan Group II, Loan Group III and Loan Group IV, based on their respective Class Principal Balances. (b) On each Distribution Date, if the aggregate Class Principal Balance of all Group I Certificates, Group II Certificates, Group III Certificates and Group IV Certificates exceeds the aggregate Stated Principal Balance of the Mortgage Loans in Loan Group I, Loan Group II, Loan Group III and Loan Group IV (after giving effect to distributions of principal and the allocation of all losses to such Certificates on such Distribution Date), such excess will be deemed by the Trustee to be a principal loss and will be allocated by the Trustee to the most junior Class of Subordinate Certificates then outstanding. (c) Any Realized Loss allocated to a Class of Certificates or any reduction in the Class Principal Balance of a Class of Certificates pursuant to Section 4.02(b) shall be allocated by the Trustee among the Certificates of such Class in proportion to their respective Certificate Balances. (d) Any allocation by the Trustee of Realized Losses to a Certificate or any reduction in the Certificate Balance of a Certificate pursuant to Section 4.02(b) shall be 77 accomplished by reducing the Certificate Balance thereof, immediately following the distributions made on the related Distribution Date in accordance with the definition of "Certificate Balance." SECTION 4.03 Reserved. SECTION 4.04 Monthly Statements to Certificateholders.

Persons that are unable to use the above website are entitled to have a paper copy mailed to them via first class mail by written notice to the Trustee addressed to the Corporate Trust Office. The Trustee shall have the right to change the way the reports referred to in this Section are distributed in order to make such distribution more convenient and/or more accessible to the above parties and to the Certificateholders. The Trustee shall provide timely and adequate notification to all above parties and to the Certificateholders regarding any such change. The Trustee may fully rely upon and shall have no liability with respect to information provided by any Servicer. (b) Upon request, within a reasonable period of time after the end of each calendar year, the Trustee shall cause to be furnished to each Person who at any time during the calendar year was a Certificateholder, a statement containing the information set forth in clauses (a)(i), (a)(ii) and (a)(vi) of this Section 4.04 aggregated for such calendar year or applicable portion thereof during which such Person was a Certificateholder.

Notwithstanding the foregoing, nothing in this Section 4.05 shall require any Servicer to collect, create, collate or otherwise generate any information that it does not generate in its usual course of business. SECTION 4.06 Cross-Collateralization; Adjustments to Available Funds (a) On each Distribution Date prior to the Credit Support Depletion Date, but after the date on which the aggregate Class Principal Balance of Senior Certificates of a Certificate Group has been reduced to zero, the Trustee shall distribute the principal portion of Available Distribution Amount on the Mortgage Loans relating to such Senior Certificates that will have been paid in full, to the holders of the Senior Certificates of the other Certificate Groups, pro rata, based on Class Principal Balances, provided, however, that the Trustee shall not make such distribution on such Distribution Date if (a) the Subordinate Pool Percentage for such Distribution Date is greater than or equal to 200% of such Subordinate Pool Percentage as of the Closing Date and (b) the average outstanding principal balance of the Mortgage Loans in each Loan Group delinquent 60 days or more over the last six months, as a percentage of the related Group C-B Component Balance, is less than 50%. (b) If on any Distribution Date the Class Principal Balance of Senior Certificates in a Certificate Group is greater than the aggregate Stated Principal Balance of the Mortgage Loans in the related Loan Group (the "Undercollateralized Group"), then the Trustee shall reduce the Available Distribution Amount of the other Loan Groups that are not undercollateralized (the "Overcollateralized Groups"), as follows: (1) to add to the Available Distribution Amount of each Undercollateralized Group an amount equal to the lesser of (a) one month's interest on the Principal Transfer Amount of each Undercollateralized Group at the Pass-Through Rate applicable to the Undercollateralized Group(s) and (b) Available Distribution Amount of the Overcollateralized Group(s) remaining after making distributions to the Certificates of the Overcollateralized Group(s) on such Distribution Date pursuant to Section 4.01; and (2) to the Senior Certificates of each Undercollateralized Group, to the extent of the principal portion of Available Distribution Amount of the Overcollateralized Group(s) remaining after making distributions to the Senior Certificates of the Overcollateralized Group(s) on such Distribution Date pursuant to Section 4.01, until the Class Principal Balance of the Senior Certificates of such 80 Undercollateralized Group(s) equals the aggregate Stated Principal Balance of the Mortgage Loans in the related Loan Group(s), any shortfall of such Available Distribution Amount to be allocated among such Undercollateralized Group(s), pro rata, based upon the respective Principal Transfer Amounts. (b) If more than one Overcollateralized Group exists on any Distribution Date, reductions in the Available Funds of such groups to make the payments required to be made pursuant to Section 4.06(b) on such Distribution Date shall be made pro rata, based on the amount of payments required to be made to the Undercollateralized Group(s). 81 ARTICLE V ADVANCES BY A SERVICER SECTION 5.01 Advances by a Servicer. Each Servicer shall deposit in the Collection Account an amount equal to all Scheduled Payments (with interest at the Mortgage Rate less the Servicing Fee Rate) which were due on the related Mortgage Loans during the applicable Collection Period and which were delinquent at the close of business on the immediately preceding Determination Date; provided, however, that with respect to any Balloon Loan that is delinquent on its maturity date, the related Servicer will not be required to advance the related balloon payment but will be required to continue to make advances in accordance with this Section 5.01 with respect to such Balloon Loan in an amount equal to an assumed scheduled payment that would otherwise be due based on the original amortization schedule for that Mortgage Loan plus one month's interest on the outstanding principal balance at the applicable Mortgage Rate less the applicable Servicing Fee Rate. Each Servicer's obligation to make such Advances as to any related Mortgage Loan will continue through the last Scheduled Payment due prior to the payment in full of such Mortgage Loan, or through the date that the related Mortgaged Property has, in the judgment of such Servicer, been completely liquidated. Each Servicer shall be obligated to make Advances in accordance with the provisions of this Agreement; provided, however, that such obligation with respect to any related Mortgage Loan shall cease if a Servicer determines, in its reasonable opinion, that Advances with respect to such Mortgage Loan are Nonrecoverable Advances. In the event that such Servicer determines that any such advances are Nonrecoverable Advances, such Servicer shall provide the Trustee with a certificate signed by a Servicing Officer evidencing such determination. If an Advance is required to be made hereunder, the related Servicer shall no later than the Servicer Remittance Date immediately preceding the Distribution Date immediately following the related Determination Date either (i) deposit in the Collection Account from its own funds an amount equal to such Advance, (ii) cause to be made an appropriate entry in the records of the Collection Account that funds in such account being held for future distribution or withdrawal have been, as permitted by this Section 5.01, used by such Servicer to make such Advance or (iii) make Advances in the form of any combination of clauses (i) and (ii) aggregating the amount of such Advance. Any such funds being held in a Collection Account for future distribution and so used shall be replaced by such Servicer from its own funds by deposit in such Collection Account on or before any future Distribution Date in which such funds would be due. 82 ARTICLE VI THE CERTIFICATES SECTION 6.01 The Certificates. The Certificates shall be in substantially the forms set forth in Exhibits A, B and C hereto, with such appropriate insertions, omissions, substitutions and other variations as are required or permitted by this Agreement or as may in the reasonable judgment of the Trustee or the Depositor be necessary, appropriate or convenient to comply, or facilitate compliance, with applicable laws, and may have such letters, numbers or other marks of identification and such legends or endorsements placed thereon as may be required to comply with the rules of any securities exchange on which any of the Certificates may be listed, or as may, consistently herewith, be determined by the officers executing such Certificates, as evidenced by their execution thereof. The definitive Certificates shall be printed, typewritten, lithographed or engraved or produced by any combination of these methods or may be produced in any other manner permitted by the rules of any securities exchange on which any of the Certificates may be listed, all as determined by the officers executing such Certificates, as evidenced by their execution thereof. The Certificates shall be issuable in registered form, in the minimum denominations, integral multiples in excess thereof (except that one Certificate in each Class may be issued in a different amount which must be in excess of the applicable minimum denomination) and aggregate denominations per Class set forth in the Preliminary Statement. The Certificates shall be executed by manual or facsimile signature on behalf of the Trustee by a Responsible Officer. Certificates bearing the manual or facsimile signatures of individuals who were, at the time when such signatures were affixed, authorized to sign on behalf of the Trustee shall bind the Trustee, notwithstanding that such individuals or any of them have ceased to be so authorized prior to the authentication and delivery of such Certificates or did not hold such offices at the date of such Certificate. 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 executed by the Trustee by manual signature, and such certificate of authentication upon any Certificate shall be conclusive evidence, and the only evidence, that such Certificate has been duly authenticated and delivered hereunder. All Certificates shall be dated the date of their authentication. SECTION 6.02 Registration of Transfer and Exchange of Certificates. (a) The Trustee shall maintain, or cause to be maintained, a Certificate Register 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. Upon surrender for registration of transfer of any Certificate, the Trustee shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Certificates in like aggregate interest and of the same Class. 83 (b) At the option of a Certificateholder, Certificates may be exchanged for other Certificates of authorized denominations and the same aggregate interest in the Trust Fund and of the same Class, upon surrender of the Certificates to be exchanged at the office or agency of the Trustee set forth in Section 6.06. 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 registration of transfer or exchange shall be accompanied by a written instrument of transfer in form satisfactory to the Trustee duly executed by the Holder thereof or his attorney duly authorized in writing. (c) No service charge to the Certificateholders shall be made for any registration of transfer or exchange of Certificates, but payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any transfer or exchange of Certificates may be required. (d) All Certificates surrendered for registration of transfer and exchange shall be canceled and subsequently destroyed by the Trustee in accordance with the Trustee's customary procedures. (e) No transfer of any Private Certificate shall be made unless that transfer is made pursuant to an effective registration statement under the 1933 Act and effective registration or qualification under applicable state securities laws, or is made in a transaction which does not require such registration or qualification. Except in connection with any transfer of a Private Certificate by the Depositor to any affiliate, in the event that a transfer is to be made in reliance upon an exemption from the 1933 Act and such laws, in order to assure compliance with the 1933 Act and such laws, the Certificateholder desiring to effect such transfer and such Certificateholder's prospective transferee shall each certify to the Trustee in writing the facts surrounding the transfer in substantially the form set forth in Exhibit L (the "Transferor Certificate") and (i) deliver a letter in substantially the form of either Exhibit M-1 (the "Investment Letter") or Exhibit M-2 (the "Rule 144A Letter") or (ii) there shall be delivered to the Trustee at the expense of the transferor an Opinion of Counsel that such transfer may be made pursuant to an exemption from the 1933 Act. The Depositor shall provide to any Holder of a Private Certificate and any prospective transferee designated by any such Holder, information regarding the related Certificates and the Mortgage Loans and such other information as shall be necessary to satisfy the condition to eligibility set forth in Rule 144A(d)(4) for transfer of any such Certificate without registration thereof under the 1933 Act pursuant to the registration exemption provided by Rule 144A. The Trustee shall cooperate with the Depositor in providing the Rule 144A information referenced in the preceding sentence, including providing to the Depositor such information regarding the Certificates, the Mortgage Loans and other matters regarding the Trust Fund in the Trustee's possession and as the Depositor shall reasonably request to meet its obligation under the preceding sentence. Each Holder of a Private Certificate desiring to effect such transfer shall, and does hereby agree to, indemnify the Trustee, the Depositor, each Seller and each 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. (f) No transfer of an ERISA-Restricted Certificate shall be made to any employee benefit or other plan that is subject to the Employee Retirement Income Security Act of 1974, as 84 amended ("ERISA"), or Section 4975 of the Code, to a trustee or other person acting on behalf of any such plan, or to any other person using "plan assets" to effect such acquisition, unless the prospective transferee of a Certificate provides the Trustee with (i) in the case of an ERISA-Restricted Certificate that has been the subject of an ERISA-Qualifying Underwriting, a certification as set forth in item (d) of Exhibit M-1 or M-2 or item 15 of Exhibit N and in the case of any other ERISA-Restricted Certificate, a certification as set forth in item d(i) of Exhibit M-1 or M-2 or item 15 of Exhibit N; or (ii) an Opinion of Counsel which establishes to the reasonable satisfaction of the Depositor and the Trustee that the purchase and holding of an ERISA-Restricted Certificate by, on behalf of or with "plan assets" of such plan is permissible under applicable local law, would not constitute or result in a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code, and would not subject the Depositor, the Trustee or the Servicer to any obligation or liability (including liabilities under ERISA or Section 4975 of the Code) in addition to those undertaken in this Agreement or any other liability. The Trustee shall require that, where applicable, such prospective transferee certify to the Trustee in writing the facts establishing that such transferee is not such a plan and is not acting on behalf of or using "plan assets" of any such plan to effect such acquisition. (g) Additional restrictions on transfers of the Class AR Certificates to Disqualified Organizations are set forth below: (i) Each Person who has or who acquires any ownership interest in a Class AR 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 Class AR Certificate are expressly subject to the following provisions: (A) Each Person holding or acquiring any ownership interest in a Class AR Certificate shall be other than a Disqualified Organization and shall promptly notify the Trustee of any change or impending change in its status as other than a Disqualified Organization. (B) In connection with any proposed transfer of any ownership interest in a Class AR Certificate to a U.S. Person, the Trustee shall require delivery to it, and shall not register the transfer of a Class AR Certificate until its receipt of (1) an affidavit and agreement (a "Transferee Affidavit and Agreement" attached hereto as Exhibit N) from the proposed transferee, in form and substance satisfactory to the Trustee, representing and warranting, among other things, that it is not a non-U.S. Person, that such transferee is other than a Disqualified Organization, that it is not acquiring its ownership interest in a Class AR Certificate that is the subject of the proposed Transfer as a nominee, trustee or agent for any Person who is a Disqualified Organization, that for so long as it retains its ownership interest in a Class AR Certificate, it will endeavor to remain other than a Disqualified Organization, and that it has reviewed the provisions of 85 this Section 6.02(g) and agrees to be bound by them, and (2) a certificate, attached hereto as Exhibit O, from the Holder wishing to transfer a Class AR Certificate, in form and substance satisfactory to the Trustee, representing and warranting, among other things, that no purpose of the proposed transfer is to allow such Holder to impede the assessment or collection of tax. (C) Notwithstanding the delivery of a Transferee Affidavit and Agreement by a proposed transferee under clause (B) above, if the Trustee has actual knowledge that the proposed transferee is a Disqualified Organization, no transfer of an ownership interest in a Class AR Certificate to such proposed transferee shall be effected. (D) Each Person holding or acquiring any ownership interest in a Class AR Certificate agrees, by holding or acquiring such ownership interest, to require a Transferee Affidavit and Agreement from the other Person to whom such Person attempts to transfer its ownership interest and to provide a certificate to the Trustee in the form attached hereto as Exhibit O. (ii) The Trustee shall register the transfer of any Class AR Certificate only if it shall have received the Transferee Affidavit and Agreement, a certificate of the Holder requesting such transfer in the form attached hereto as Exhibit O and all of such other documents as shall have been reasonably required by the Trustee as a condition to such registration. (iii) (A) If any Disqualified Organization shall become a Holder of a Class AR Certificate, then the last preceding Holder that was not a Disqualified Organization shall be restored, to the extent permitted by law, to all rights and obligations as Holder thereof retroactive to the date of registration of such transfer of such Class AR Certificate. If any non-U.S. Person shall become a Holder of a Class AR Certificate, then the last preceding Holder that is a U.S. Person shall be restored, to the extent permitted by law, to all rights and obligations as Holder thereof retroactive to the date of registration of the transfer to such non-U.S. Person of such Class AR Certificate. If a transfer of a Class AR Certificate is disregarded pursuant to the provisions of Treasury Regulations Section 1.860E-1 or Section 1.860G-3, then the last preceding Holder that was not a Disqualified Organization shall be restored, to the extent permitted by law, to all rights and obligations as Holder thereof retroactive to the date of registration of such transfer of such Class AR Certificate. The Trustee shall be under no liability to any Person for any registration of transfer of a Class AR Certificate that is in fact not permitted by this Section 6.02(g) 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 of a Class AR Certificate shall become a Holder of a Class AR Certificate in violation of the restrictions in this Section 6.02(g) and to the extent that the retroactive restoration of the rights of the Holder of such Class AR Certificate as described in clause (iii)(A) above shall be invalid, illegal or unenforceable, then the Depositor shall have the right, without 86 notice to the Holder or any prior Holder of such Class AR Certificate, to sell such Class AR Certificate to a purchaser selected by the Depositor on such terms as the Depositor may choose. Such purported transferee shall promptly endorse and deliver a Class AR Certificate in accordance with the instructions of the Depositor. Such purchaser may be the Depositor itself or any affiliate of the Depositor. The proceeds of such sale, net of the commissions (which may include commissions payable to the Depositor or its affiliates), expenses and taxes due, if any, shall be remitted by the Depositor 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 Depositor, and the Depositor shall not be liable to any Person having an ownership interest or a purported ownership interest in a Class AR Certificate as a result of its exercise of such discretion. (iv) Each Servicer, on behalf of the Trustee, shall make available, upon written request from the Trustee, all information reasonably available to it that is necessary to compute any tax imposed (A) as a result of the transfer of an ownership interest in a Class AR Certificate to any Person who is not other than a Disqualified Organization, including the information regarding "excess inclusions" of such Residual Certificate required to be provided to the Internal Revenue Service and certain Persons as described in Treasury Regulation Section 1.860D-1(b)(5), and (B) as a result of any regulated investment company, real estate investment trust, common trust fund, partnership, trust, estate or organizations described in Section 1381 of the Code having as among its record holders at any time any Person who is not other than a Disqualified Organization. Reasonable compensation for providing such information may be required by the Servicer from such Person. (v) The provisions of this Section 6.02(g) set forth prior to this Section (v) may be modified, added to or eliminated by the Depositor, provided that there shall have been delivered to the Trustee 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 rating of the Certificates; and (B) a certificate of the Depositor stating that the Depositor has received an Opinion of Counsel, in form and substance satisfactory to the Depositor, to the effect that such modification, addition to or elimination of such provisions will not cause the Trust Fund to cease to qualify as a REMIC and will not create a risk that (i) the Trust Fund may be subject to an entity-level tax caused by the transfer of a Class AR Certificate to a Person which is a Disqualified Organization or (2) a Certificateholder or another Person will be subject to a REMIC-related tax caused by the transfer of applicable Class AR Certificate to a Person which is a Disqualified Organization. 87 (vi) The following legend shall appear on each Class AR Certificate: ANY RESALE, TRANSFER OR OTHER DISPOSITION OF THIS CERTIFICATE MAY BE MADE ONLY IF THE PROPOSED TRANSFEREE PROVIDES A TRANSFER AFFIDAVIT TO THE TRUSTEE THAT (1) SUCH TRANSFEREE IS NOT (A) THE UNITED STATES, ANY STATE OR POLITICAL SUBDIVISION THEREOF, ANY FOREIGN GOVERNMENT, ANY INTERNATIONAL ORGANIZATION, OR ANY AGENCY OR INSTRUMENTALITY OF ANY OF THE FOREGOING, (B) ANY ORGANIZATION (OTHER THAN A COOPERATIVE DESCRIBED IN SECTION 521 OF THE CODE) WHICH IS EXEMPT FROM THE TAX IMPOSED BY CHAPTER 1 OF THE CODE UNLESS SUCH ORGANIZATION IS SUBJECT TO THE TAX IMPOSED BY SECTION 511 OF THE CODE, (C) ANY ORGANIZATION DESCRIBED IN SECTION 1381(a)(2)(C) OF THE CODE (ANY SUCH PERSON DESCRIBED IN THE FOREGOING CLAUSES (A), (B), OR (C) BEING HEREINAFTER REFERRED TO AS A "DISQUALIFIED ORGANIZATION"), OR (D) AN AGENT OF A DISQUALIFIED ORGANIZATION AND (2) NO PURPOSE OF SUCH TRANSFER IS TO ENABLE THE TRANSFEROR TO IMPEDE THE ASSESSMENT OR COLLECTION OF TAX. SUCH AFFIDAVIT SHALL INCLUDE CERTAIN REPRESENTATIONS AS TO THE FINANCIAL CONDITION OF THE PROPOSED TRANSFEREE. NOTWITHSTANDING THE REGISTRATION IN THE CERTIFICATE REGISTER OF ANY TRANSFER, SALE OR OTHER DISPOSITION OF THIS CLASS AR CERTIFICATE TO A DISQUALIFIED ORGANIZATION OR AN AGENT 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 HEREUNDER, INCLUDING, BUT NOT LIMITED TO, THE RECEIPT OF DISTRIBUTIONS ON THIS CERTIFICATE. EACH HOLDER OF THE CLASS AR CERTIFICATE BY ACCEPTANCE OF THIS CERTIFICATE SHALL BE DEEMED TO HAVE CONSENTED TO THE PROVISIONS OF THIS PARAGRAPH. (h) The Trustee shall have no liability to the Trust Fund arising from a transfer of any such Certificate in reliance upon a certification, ruling or Opinion of Counsel described in this Section 6.02; provided, however, that the Trustee shall not register the transfer of any Class AR Certificate if it has actual knowledge that the proposed transferee does not meet the qualifications of a permitted Holder of a Class AR Certificate as set forth in this Section 6.02. SECTION 6.03 Mutilated, Destroyed, Lost or Stolen Certificates. If (a) any mutilated Certificate is surrendered to the Trustee, or the Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Certificate and (b) there is delivered to each Servicer and the Trustee such security or indemnity as may be required by them to save each of them harmless, then, in the absence of notice to the Trustee that such Certificate has been acquired by a bona fide purchaser, the Trustee shall execute, 88 authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new Certificate of like tenor and interest in the Trust Fund. In connection with the issuance of any new Certificate under this Section 6.03, the Trustee may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith. Any replacement Certificate issued pursuant to this Section 6.03 shall constitute complete and indefeasible evidence of ownership in the Trust Fund, as if originally issued, whether or not the lost, stolen or destroyed Certificate shall be found at any time. SECTION 6.04 Persons Deemed Owners. Prior to due presentation of a Certificate for registration of transfer, each Servicer, the Trustee, and any agent of any Servicer or the Trustee may treat the person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in this Agreement and for all other purposes whatsoever, and none of the Servicers, the Trustee, nor any agent of a Servicer or the Trustee shall be affected by any notice to the contrary. SECTION 6.05 Access to List of Certificateholders' Names and Adresses. (a) If three or more Certificateholders (i) request in writing from the Trustee a list of the names and addresses of Certificateholders, (ii) state that such Certificateholders desire to communicate with other Certificateholders with respect to their rights under this Agreement or under the Certificates and (iii) provide a copy of the communication which such Certificateholders propose to transmit, then the Trustee shall, within ten Business Days after the receipt of such request, afford such Certificateholders access during normal business hours to a current list of the Certificateholders. The expense of providing any such information requested by a Certificateholder shall be borne by the Certificateholders requesting such information and shall not be borne by the Trustee. Every Certificateholder, by receiving and holding a Certificate, agrees that the Trustee shall not be held accountable by reason of the disclosure of any such information as to the list of the Certificateholders hereunder, regardless of the source from which such information was derived. (b) Each Servicer, so long as it is a servicer hereunder, the Sellers and the Depositor shall have unlimited access to a list of the names and addresses of the Certificateholders which list shall be provided by the Trustee promptly upon request. SECTION 6.06 Maintenance of Office or Agency. The Trustee will maintain or cause to be maintained at its expense an office or offices or agency or agencies in New York City where Certificates may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Trustee in respect of the Certificates and this Agreement may be served. The Trustee initially designates the Corporate Trust Office as its office for such purpose. The Trustee will give prompt written notice to the Certificateholders of any change in the location of any such office or agency. 89 SECTION 6.07 Book-Entry Certificates. Notwithstanding the foregoing, the Book-Entry Certificates, upon original issuance, shall be issued in the form of one or more typewritten Certificates representing the Book-Entry Certificates, to be delivered to DTC, the initial Clearing Agency, by, or on behalf of, the Depositor. The Book-Entry Certificates shall initially be registered on the Certificate Register in the name of Cede & Co., the nominee of DTC, as the initial Clearing Agency, and no Beneficial Holder will receive a definitive certificate representing such Beneficial Holder's interest in the Certificates, except as provided in Section 6.09. Unless and until definitive, fully registered Certificates ("Definitive Certificates") have been issued to the Beneficial Holders pursuant to Section 6.09: (a) the provisions of this Section 6.07 shall be in full force and effect with respect to the Book-Entry Certificates; (b) the Depositor and the Trustee may deal with the Clearing Agency for all purposes with respect to the Book-Entry Certificates (including the making of distributions on such Certificates) as the sole Holder of such Certificates; (c) to the extent that the provisions of this Section 6.07 conflict with any other provisions of this Agreement, the provisions of this Section 6.07 shall control; and (d) the rights of the Beneficial Holders of the Book-Entry Certificates shall be exercised only through the Clearing Agency and the Participants and shall be limited to those established by law and agreements between such Beneficial Holders and the Clearing Agency and/or the Participants. Pursuant to the Depository Agreement, unless and until Definitive Certificates are issued pursuant to Section 6.09, the initial Clearing Agency will make book-entry transfers among the Participants and receive and transmit distributions of principal and interest on the related Book-Entry Certificates to such Participants. For purposes of any provision of this Agreement requiring or permitting actions with the consent of, or at the direction of, Holders of the Book-Entry Certificates evidencing a specified percentage of the aggregate unpaid principal amount of such Certificates, such direction or consent may be given by the Clearing Agency at the direction of Beneficial Holders owning such Certificates evidencing the requisite percentage of principal amount of such Certificates. The Clearing Agency may take conflicting actions with respect to the Book-Entry Certificates to the extent that such actions are taken on behalf of the Beneficial Holders. SECTION 6.08 Notices to Clearing Agency. Whenever notice or other communication to the Holders of Book-Entry Certificates is required under this Agreement, unless and until Definitive Certificates shall have been issued to the related Certificateholders pursuant to Section 6.09, the Trustee shall give all such notices and communications specified herein to be given to Holders of the Book-Entry Certificates to the Clearing Agency which shall give such notices and communications to the related Participants in accordance with its applicable rules, regulations and procedures. 90 SECTION 6.09 Definitive Certificates. If (a) the Depositor advises the Trustee in writing that the Clearing Agency is no longer willing or able to properly discharge its responsibilities under the Depository Agreement with respect to the Certificates and the Depositor is unable to locate a qualified successor, (b) the Depositor, at its option, advises the Trustee in writing that it elects to terminate the book-entry system with respect to the Book-Entry Certificates through the Clearing Agency or (c) after the occurrence of an Event of Default, Holders of Book-Entry Certificates evidencing not less than 66K% of the aggregate Class Principal Balance of the Book-Entry Certificates advise the Trustee in writing that the continuation of a book-entry system with respect to the such Certificates through the Clearing Agency is no longer in the best interests of the Holders of such Certificates with respect to the Book-Entry Certificates, the Trustee shall notify all Holders of such Certificates of the occurrence of any such event and the availability of Definitive Certificates. Upon surrender to the Trustee of such Certificates by the Clearing Agency, accompanied by registration instructions from the Clearing Agency for registration, the Trustee shall authenticate and deliver the Definitive Certificates. Neither the Depositor nor the Trustee shall be liable for any delay in 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 Clearing Agency 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 Definitive Certificates as Certificateholders hereunder. 91 ARTICLE VII THE DEPOSITOR, THE SELLERS, THE SERVICERS AND THE SPECIAL SERVICER SECTION 7.01 Liabilities of the Sellers, the Depositor, the Servicers and the Special Servicer. The Depositor, the Special Servicer, any Seller and any Servicer shall each be liable in accordance herewith only to the extent of the obligations specifically and respectively imposed upon and undertaken by them herein. SECTION 7.02 Merger or Consolidation of the Depositor, the Sellers, the Servicers or the Special Servicer. Subject to the immediately succeeding paragraph, the Depositor, the Special Servicer, any Seller and any Servicer will each do or cause to be done all things necessary to preserve and keep in full force and effect its existence, rights and franchises (charter and statutory) and will each 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, or any of the Mortgage Loans and to perform its respective duties under this Agreement. Any Person into which the Depositor, the Special Servicer, any Seller or any Servicer may be merged or consolidated, or any Person resulting from any merger or consolidation to which the Depositor, the Special Servicer, any Seller or any Servicer shall be a party, or any Person succeeding to the business of the Depositor, the Special Servicer, any Seller or any Servicer, shall be the successor of the Depositor, the Special Servicer, such Seller or such 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 any such Servicer shall be qualified to sell mortgage loans to, and to service mortgage loans on behalf of, FNMA or FHLMC. Notwithstanding anything else in this Section 7.02 or in Section 7.04 hereof to the contrary, a Servicer may assign its rights and delegate its duties and obligations under this Agreement; provided, however, that such Servicer gives the Depositor and the Trustee notice of such assignment; and provided further, that such purchaser or transferee accepting such assignment and delegation shall be an institution that is a FNMA and FHLMC approved seller/servicer in good standing, which has a net worth of at least $15,000,000, and which is willing to service the Mortgage Loans and executes and delivers to the Depositor and the Trustee an agreement accepting such delegation and assignment, which contains an assumption by such Person of the rights, powers, duties, responsibilities, obligations and liabilities of such Servicer, with like effect as if originally named as a party to this Agreement; and provided further, that each of the Rating Agencies acknowledge that its rating of the Certificates in effect immediately prior to such assignment will not be qualified or reduced as a result of such assignment and delegation. In the case of any such assignment and delegation, such Servicer shall be released from its obligations under this Agreement (except as provided above), except that the Servicer 92 shall remain liable for all liabilities and obligations incurred by it as Servicer hereunder prior to the satisfaction of the conditions to such assignment and delegation set forth in the preceding sentence. SECTION 7.03 Limitation on Liability of the Depositor, the Sellers, the Servicers, the Special Servicer and Others. Neither the Depositor, the Special Servicer, any Servicer, any Seller nor any of the directors, officers, employees or agents of the Depositor, the Special Servicer, any Servicer or any Seller shall be under any liability to the Certificateholders for any action taken or for refraining from the taking of any action in good faith pursuant to this Agreement, or for errors in judgment; provided, however, that this provision shall not protect the Depositor, the Special Servicer, any Servicer or any Seller against any breach of representations or warranties made by it herein or protect the Depositor, the Special Servicer, any Servicer or any Seller or any such director, officer, employee or agent from any liability which would otherwise be imposed by reasons of willful misfeasance, bad faith or gross negligence in the performance of duties or by reason of reckless disregard of obligations and duties hereunder. The Depositor, the Special Servicer, any Servicer, any Seller and any director, officer, employee or agent of the Depositor, the Special Servicer, any Servicer or any Seller may rely in good faith on any document of any kind prima facie properly executed and submitted by any Person respecting any matters arising hereunder. The Depositor, the Special Servicer, any Servicer, any Seller and any director, officer, employee or agent of the Depositor, the Special Servicer, any Servicer or any Seller shall be indemnified by the Trust Fund and held harmless against any loss, liability or expense incurred in connection with any legal action relating to this Agreement or the Certificates, other than 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. None of the Depositor, the Special Servicer, any Servicer or any Seller shall be under any obligation to appear in, prosecute or defend any legal action that is not incidental to their respective duties hereunder and which in its opinion may involve it in any expense or liability; provided, however, that the Depositor, the Special Servicer , any Servicer or any Seller may in its discretion undertake any such action that it may deem necessary or desirable in respect of this Agreement and the rights and duties of the parties hereto and interests of the Trustee and the Certificateholders hereunder. SECTION 7.04 Servicer and Special Servicer Not to Resign; Transfer of Servicing. (a) A Servicer or Special Servicer shall not resign from the obligations and duties hereby imposed on it except (i) upon appointment of a successor servicer or special servicer and receipt by the Trustee of a letter from each Rating Agency that such a resignation and appointment will not result in a downgrading of the rating of any of the Certificates related to the applicable Mortgage Loans, or (ii) upon determination that its duties hereunder are no longer permissible under applicable law. Any such determination under clause (ii) permitting the resignation of a Servicer or Special Servicer shall be evidenced by an Opinion of Counsel to such effect delivered to the Trustee. No such resignation shall become effective until the successor servicer shall have assumed such Servicer's or Special Servicer's responsibilities, duties, liabilities and obligations hereunder in accordance with Section 8.02 hereof. 93 (b) Notwithstanding the foregoing, DLJ Mortgage Capital, Inc. or its transferee shall be entitled to request that a Servicer, other than WMMSC, or the Special Servicer, resign and appoint a successor servicer or special servicer; provided that such entity delivers to the Trustee the letter required in Section 7.04(a)(i) above. SECTION 7.05 Sellers, Servicers and Special Servicer May Own Certificates. Each of the Sellers, Servicers and Special Servicer in its individual or any other capacity may become the owner or pledgee of Certificates with the same rights as it would have if it were not a Seller, Servicer or Special Servicer. 94 ARTICLE VIII DEFAULT SECTION 8.01 Events of Default. "Event of Default", wherever used herein, and as to each Servicer, means any one of the following events (whatever reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body): (a) any failure by the Servicer to remit to the Certificate Account or to the Trustee any payment other than an Advance required to be made by the Servicer under the terms of this Agreement, which failure shall continue unremedied for a period of one Business Day after the date upon which written notice of such failure shall have been given to the Servicer by the Trustee or the Depositor or to the Servicer and the Trustee by the Holders of Certificates having not less than 25% of the Voting Rights evidenced by the Certificates; or (b) any failure by the Servicer to observe or perform in any material respect any other of the covenants or agreements on the part of the Servicer contained in this Agreement (except as set forth in (c) and (g) below) which failure (i) materially affects the rights of the Certificateholders and (ii) shall continue unremedied for a period of 60 days after the date on which written notice of such failure shall have been given to the Servicer by the Trustee or the Depositor, or to the Servicer and the Trustee by the Holders of Certificates evidencing not less than 25% of the Voting Rights evidenced by the Certificates; or (c) if a representation or warranty set forth in Section 2.03 hereof made solely in its capacity as a Servicer shall prove to be materially incorrect as of the time made in any respect that materially and adversely affects interests of the Certificateholders, and the circumstances or condition in respect of which such representation or warranty was incorrect shall not have been eliminated or cured within 90 days after the date on which written notice thereof shall have been given to the Servicer and Sellers by the Trustee for the benefit of the Certificateholders or by the Depositor; or (d) a decree or order of a court or agency or supervisory authority having jurisdiction in the premises for the appointment of a conservator or receiver or liquidator in any insolvency, readjustment of debt, marshalling of assets and liabilities or similar proceedings, or for the winding-up or liquidation of its affairs, shall have been entered against the Servicer and such decree or order shall have remained in force undischarged or unstayed for a period of 60 days; or (e) the Servicer shall consent to the appointment of a conservator or receiver or liquidator in any insolvency, readjustment of debt, marshalling of assets and liabilities or similar proceedings of or relating to the Servicer or all or substantially all of the property of the Servicer; or 95 (f) the Servicer shall admit in writing its inability to pay its debts generally as they become due, file a petition to take advantage of, or commence a voluntary case under, any applicable insolvency or reorganization statute, make an assignment for the benefit of its creditors, or voluntarily suspend payment of its obligations; or (g) any failure of the Servicer to make any Advance in the manner and at the time required to be made from its own funds pursuant to this Agreement and after receipt of notice from the Trustee pursuant to Section 5.01, which failure continues unremedied after 5 p.m., New York City time, on the Business Day immediately following the Servicer's receipt of such notice. If an Event of Default due to the actions or inaction of a Servicer described in clauses (a) through (f) of this Section shall occur, then, and in each and every such case, so long as such Event of Default shall not have been remedied, the Trustee shall at the direction of the Holders of Certificates evidencing not less than 25% of the Voting Rights evidenced by the Certificates, by notice in writing to such Servicer (with a copy to the Rating Agencies), terminate all of the rights and obligations of such Servicer under this Agreement (other than rights to reimbursement for Advances and Servicing Advances previously made, as provided in Section 3.08). If an Event of Default described in clause (g) shall occur, the Trustee shall, prior to the next Distribution Date, terminate the rights and obligations of the applicable Servicer hereunder and succeed to the rights and obligations of such Servicer hereunder pursuant to Section 8.02, including the obligation to make Advances on such succeeding Distribution Date pursuant to the terms hereof. No Event of Default with respect to a Servicer shall affect the rights or duties of any other Servicer, or constitute an Event of Default as to any other Servicer. SECTION 8.02 Trustee to Act; Appointment of Successor. On and after the time a Servicer receives a notice of termination pursuant to Section 8.01 hereof or resigns pursuant to Section 7.04 hereof, subject to the provisions of Section 3.04 hereof, the Trustee shall be the successor in all respects to such Servicer in its capacity as servicer under this Agreement and with respect to the transactions set forth or provided for herein and shall be subject to all the responsibilities, duties and liabilities relating thereto placed on such Servicer by the terms and provisions hereof. As compensation therefor, the Trustee shall be entitled to all funds relating to the Mortgage Loans that the related Servicer would have been entitled to charge to the related Collection Account if such Servicer had continued to act hereunder (except that the terminated or resigning Servicer shall retain the right to be reimbursed for advances (including, without limitation, Advances and Servicing Advances) theretofore made by the Servicer with respect to which it would be entitled to be reimbursed as provided in Section 3.08 if it had not been so terminated or resigned as Servicer). Notwithstanding the foregoing, if the Trustee has become the successor to a Servicer in accordance with this Section 8.02, the Trustee may, if it shall be unwilling to so act, or shall, if it is unable to so act (exclusive of the obligations with respect to Advances), appoint, or petition a court of competent jurisdiction to appoint, any established mortgage loan servicing institution, the appointment of which does not adversely affect the then current rating of the Certificates, as the successor to a Servicer hereunder in the assumption of all or any part of the responsibilities, duties or liabilities of such Servicer. Pending appointment of a successor to a Servicer 96 hereunder, the Trustee, unless the Trustee is prohibited by law from so acting, shall act in such capacity as provided herein. In connection with such appointment and assumption, the Trustee may make such arrangements for the compensation of such successor out of payments on Mortgage Loans as it and such successor shall agree; provided, however, that no such compensation shall be in excess of that permitted the related Servicer hereunder. The Trustee and such successor shall take such action, consistent with this Agreement, as shall be necessary to effectuate any such succession. Neither the Trustee nor any other successor servicer shall be deemed to be in default hereunder by reason of any failure to make, or any delay in making, any distribution hereunder or any portion thereof caused by the failure of the applicable Servicer to deliver, or any delay in delivering, cash, documents or records to it. A Servicer that has been terminated shall, at the request of the Trustee but at the expense of such Servicer, deliver to the assuming party all documents and records relating to each Sub-Servicing Agreement and the related Mortgage Loans and an accounting of amounts collected and held by it and otherwise use commercially reasonable efforts to effect the orderly and efficient transfer of each Sub-Servicing Agreement, but only to the extent of the Mortgage Loans serviced thereunder, to the assuming party. Each Servicer shall cooperate with the Trustee and any successor servicer in effecting the termination of the terminated Servicer's responsibilities and rights hereunder, including without limitation, the transfer to such successor for administration by it of all cash amounts which shall at the time be credited by such Servicer to the applicable Collection Account or thereafter received with respect to the Mortgage Loans. Neither the Trustee nor any other successor servicer shall be deemed to be in default hereunder by reason of any failure to make, or any delay in making, any distribution hereunder or any portion thereof caused by (a) the failure of any Servicer to (i) deliver, or any delay in delivering, cash, documents or records to it, (ii) cooperate as required by this Agreement, or (iii) deliver the applicable documents and records relating to Mortgage Loans to the Trustee as required by this Agreement, or (b) restrictions imposed by any regulatory authority having jurisdiction over the related Servicer. Any successor to a Servicer as servicer shall during the term of its service as servicer maintain in force the policy or policies that such Servicer is required to maintain pursuant to Section 3.09(b) hereof. SECTION 8.03 Notification to Certificateholders. (a) Upon any termination or appointment of a successor to any Servicer, the Trustee shall give prompt written notice thereof to the Sellers, and the Certificateholders at their respective addresses appearing in the Certificate Register and to the Rating Agencies. (b) Within two Business Days after the occurrence of any Event of Default, the Trustee shall transmit by mail to the Sellers and all Certificateholders, and the Rating Agencies notice of each such Event of Default hereunder known to the Trustee, unless such Event of Default shall have been cured or waived. 97 SECTION 8.04 Waiver of Events of Default. The Holders representing at least 66% of the Voting Rights of Certificates affected by a default or Event of Default hereunder may waive any default or Event of Default; provided, however, that (a) a default or Event of Default under clause (g) of Section 8.01 may be waived, only by all of the Holders of Certificates affected by such default or Event of Default and (b) no waiver pursuant to this Section 8.04 shall affect the Holders of Certificates in the manner set forth in Section 11.01(b)(i), (ii) or (iii). Upon any such waiver of a default or Event of Default by the Holders representing the requisite percentage of Voting Rights of Certificates affected by such default or Event of Default, such default or Event of Default shall cease to exist and shall be deemed to have been cured and remedied for every purpose hereunder. No such waiver shall extend to any subsequent or other default or Event of Default or impair any right consequent thereon except to the extent expressly so waived. 98 ARTICLE IX CONCERNING THE TRUSTEE SECTION 9.01 Duties of Trustee. The Trustee, prior to the occurrence of an Event of Default and after the curing or waiver of all Events of Default that may have occurred, undertakes with respect to the Trust Fund to perform such duties and only such duties as are specifically set forth in this Agreement. In case an Event of Default has occurred and remains uncured, 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 set forth 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 the Trustee that 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. The Trustee shall have no duty to recompute, recalculate or verify the accuracy of any resolution, certificate, statement, opinion, report, document, order or other instrument so furnished to the Trustee. 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, its negligent failure to perform its obligations in compliance with this Agreement, or any liability which would be imposed by reason of its willful misfeasance or bad faith; provided, however, that: (a) prior to the occurrence of an Event of Default, and after the curing or of all such Events of Default that may have occurred, the duties and obligations of the Trustee shall be determined solely by the express provisions of this Agreement, the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Agreement, no implied covenants or obligations shall be read into this Agreement against the Trustee and the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of this Agreement which it reasonably believed in good faith to be genuine and to have been duly executed by the proper authorities respecting any matters arising hereunder; (b) the Trustee shall not be liable for an error of judgment made in good faith by a Responsible Officer or Responsible Officers of the Trustee, unless the Trustee was negligent in ascertaining or investigating the pertinent facts; (c) the Trustee shall not be liable with respect to any action taken, suffered or omitted to be taken by it in good faith in accordance with the direction of the Holders of Certificates evidencing not less than 25% of the Voting Rights allocated to each Class of Certificates relating to the time, method and place of conducting any 99 proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Agreement; and (d) no provision of this Agreement shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it. Except with respect to an Event of Default described in clause (a) of Section 8.01, the Trustee shall not be deemed to have knowledge of any Event of Default or event which, with notice or lapse of time, or both, would become an Event of Default, unless a Responsible Officer of the Trustee shall have received written notice thereof from a Servicer, the Depositor, or a Certificateholder, or a Responsible Officer of the Trustee has actual notice thereof, and in the absence of such notice no provision hereof requiring the taking of any action or the assumption of any duties or responsibility by the Trustee following the occurrence of any Event of Default or event which, with notice or lapse of time or both, would become an Event of Default, shall be effective as to the Trustee. The Trustee shall have no duty hereunder with respect to any complaint, claim, demand, notice or other document it may receive or which may be alleged to have been delivered to or served upon it by the parties as a consequence of the assignment of any Mortgage Loan hereunder; provided, however, that the Trustee shall use its best efforts to remit to the Servicer upon receipt of any such complaint, claim, demand, notice or other document (i) which is delivered to the Corporate Trust Office of the Trustee, (ii) of which a Responsible Officer has actual knowledge, and (iii) which contains information sufficient to permit the Trustee to make a determination that the real property to which such document relates is a Mortgaged Property. SECTION 9.02 Certain Matters Affecting the Trustee. (a) Except as otherwise provided in Section 9.01: (i) the Trustee may request and rely upon and shall be protected in acting or refraining from acting upon any resolution, Officer's Certificate, certificate of auditors, Servicing Officers or any other certificate, statement, instrument, opinion, report, notice, request, consent, order, appraisal, bond or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties; (ii) the Trustee may consult with counsel, financial advisors or accountants and any advice of such Persons or Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken or suffered or omitted by it hereunder in good faith and in accordance with such advice or Opinion of Counsel; (iii) the Trustee shall be under no obligation to exercise any of the trusts or powers vested in it by this Agreement or to institute, conduct or defend any litigation hereunder or in relation hereto at the request, order or direction of any of the Certificateholders pursuant to the provisions of this Agreement, unless such Certificateholders shall have offered to the Trustee reasonable security or indemnity 100 against the costs, expenses and liabilities which may be incurred therein or thereby; nothing contained herein shall, however, relieve the Trustee of the obligation, upon the occurrence of an Event of Default (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 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 an Event of Default hereunder and after the curing or waiver of all Events of Default that 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 so to do by Holders of Certificates evidencing not less than 25% of the Voting Rights allocated to each Class of Certificates; provided, however, that if the payment within a reasonable time to the Trustee of the costs, expenses or liabilities likely to be incurred by it in the making of such investigation is, in the opinion of the Trustee, not reasonably assured to the Trustee by the security afforded to it by the terms of this Agreement, the Trustee may require reasonable indemnity against such expense or liability as a condition to taking any such action; the reasonable expense of every such investigation shall be paid by the applicable Servicer in the event that such investigation relates to an Event of Default by such Servicer, if an Event of Default by such Servicer shall have occurred and is continuing, and otherwise by the Certificateholders requesting the investigation; (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 the Trustee shall not be responsible for any misconduct or negligence on the part of any such agent or attorney appointed with due care; (vii) the Trustee shall not be required to expend its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such liability is not assured to it; and (viii) the Trustee shall not be liable for any loss on any investment of funds pursuant to this Agreement except as provided in Section 3.05(e). (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. 101 SECTION 9.03 Trustee Not Liable for Certificates or Mortgage Loans. The recitals contained herein shall be taken as the statements of the Depositor or a Servicer, as the case may be, and the Trustee assumes no responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Agreement, the Certificates or of any Mortgage Loan or related document. The Trustee shall not be accountable for the use or application by the Depositor, the Sellers or the Servicers of any funds paid to the Depositor or any Servicer in respect of the Mortgage Loans or deposited in or withdrawn from a Collection Account, an Escrow Account or the Certificate Account by the Depositor, the Sellers or the Servicers. SECTION 9.04 Trustee May Own Certificates. The Trustee in its individual or any other capacity may become the owner or pledgee of Certificates with the same rights as it would have if it were not the Trustee. SECTION 9.05 Trustee's Fees and Expenses. (a) The Trustee shall pay to itself on each Distribution Date from amounts on deposit in the Certificate Account, an amount equal to the Trustee Fee in accordance with Section 4.01(A), and shall be entitled to withdraw from the Certificate Account on each Distribution Date prior to making distributions pursuant to Section 4.01 any investment income or other benefit derived from balances in the Certificate Account for such Distribution Date pursuant to Section 3.08(b). Subject to the limitations set forth in Section 9.05(b), the Trustee and any director, officer, employee or agent of the Trustee shall be indemnified by DLJMC and held harmless against any loss, liability or expense (including reasonable attorney's fees and expenses) (i) incurred in connection with any claim or legal action relating to (a) this Agreement, (b) the Certificates, (c) the Custodial Agreement, (d) the Terms Agreement or (e) the performance of any of the Trustee's duties hereunder, other than any loss, liability or expense incurred by reason of willful misfeasance, bad faith or negligence in the performance of any of the Trustee's duties hereunder or incurred by reason of any action of the Trustee taken at the direction of the Certificateholders and (ii) resulting from any error in any tax return prepared by a Servicer. Such indemnity shall survive the termination of this Agreement or the resignation or removal of the Trustee hereunder. Without limiting the foregoing, DLJMC covenants and agrees, except as otherwise agreed upon in writing by DLJMC and the Trustee and subject to the limitation set forth in this Section 9.05(b), and except for any such expense, disbursement or advance as may arise from the Trustee's negligence, bad faith or willful misconduct, to pay or reimburse the Trustee, for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any of the provisions of this Agreement with respect to: (A) the reasonable compensation and the expenses and disbursements of its counsel not associated with the closing of the issuance of the Certificates, (B) the reasonable compensation, expenses and disbursements of any accountant, engineer or appraiser that is not regularly employed by the Trustee, to the extent that the Trustee must engage such persons to perform acts or services hereunder, (C) printing and engraving expenses in connection with preparing any Definitive Certificates and (D) any other reasonable expenses incurred other than in the ordinary course of its business by the Trustee in connection with its duties hereunder.

(b) Notwithstanding anything to the contrary in this Agreement, DLJMC shall not be obligated to pay to the Trustee more than, in the aggregate, $75,000 pursuant to Section 9.05(a) hereof. SECTION 9.06 Eligibility Requirements for Trustee. The Trustee hereunder shall at all times be a corporation or association having its principal office in a state and city acceptable to the Depositor and organized and doing business under the laws of such state or the United States of America, authorized under such laws to exercise corporate trust powers, having ratings on its long-term debt obligations at the time of such appointment in at least the third highest rating category by both Moody's and S&P or such lower ratings as will not cause Moody's or S&P to lower their then-current ratings of the Class A Certificates, having a combined capital and surplus of at least $50,000,000 and subject to supervision or examination by federal or state authority. If such corporation or association publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section 9.06 the combined capital and surplus of such corporation or association shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. In case at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section 9.06, the Trustee shall resign immediately in the manner and with the effect specified in Section 9.07 hereof. SECTION 9.07 Resignation and Removal of Trustee. The Trustee may at any time resign and be discharged from the trusts hereby created by (a) giving written notice of resignation to the Depositor, the Sellers and the Servicers and by mailing notice of resignation by first class mail, postage prepaid, to the Certificateholders at their addresses appearing on the Certificate Register, and to the Rating Agencies, not less than 60 days before the date specified in such notice when, subject to Section 9.08, such resignation is to take effect, and (b) acceptance by a successor trustee in accordance with Section 9.08 meeting the qualifications set forth in Section 9.06. If at any time the Trustee shall cease to be eligible in accordance with the provisions of Section 9.06 hereof and shall fail to resign after written request thereto by the Depositor, or if at any time the Trustee shall become incapable of acting, or shall be adjudged a 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 or if the Trustee breaches any of its obligations or representations hereunder, then the Depositor may remove the Trustee and appoint a successor trustee by written instrument, in duplicate, one copy of which instrument shall be delivered to the Trustee and one copy to the successor trustee. The Trustee may also be removed at any time by the Holders of Certificates evidencing not less than 50% of the Voting Rights evidenced by the Certificates. Notice of any removal of the Trustee and acceptance of appointment by the successor trustee shall be given to the Rating Agencies by the Depositor. 103 If no successor trustee shall have been so appointed and have accepted appointment within 30 days after the giving of such notice of resignation or receipt of a notice of removal, the resigning Trustee may, at the Trust Fund's expense, petition any court of competent jurisdiction for the appointment of a successor trustee. Any resignation or removal of the Trustee and appointment of a successor trustee pursuant to any of the provisions of this Section 9.07 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 9.08 hereof. SECTION 9.08 Successor Trustee. Any successor trustee appointed as provided in Section 9.07 hereof shall execute, acknowledge and deliver to the Depositor and to its predecessor trustee an instrument accepting such appointment hereunder and thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, 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 Depositor, upon receipt of all amounts due it hereunder, 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 9.08 unless at the time of such acceptance such successor trustee shall be eligible under the provisions of Section 9.06 hereof and its acceptance shall not adversely affect the then current rating of the Certificates. Upon acceptance of appointment by a successor trustee as provided in this Section 9.08, 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 ten 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 9.09 Merger or Consolidation of Trustee. Any Person into which the Trustee may be merged or converted or with which it may be consolidated or any Person resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any Person succeeding to the business of the Trustee, shall be the successor of the Trustee hereunder, provided that such Person shall be eligible under the provisions of Section 9.06 hereof without the execution or filing of any paper or further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding. SECTION 9.10 Appointment of Co-Trustee or Separate Trustee. Notwithstanding any other provisions of this Agreement, at any time, for the purpose of meeting any legal requirements of any jurisdiction in which any part of the Trust Fund or property securing any Mortgage Note may at the time be located, the Servicers and the Trustee acting jointly shall have the power and shall execute and deliver all instruments to appoint one or more Persons approved by the Trustee to act as co-trustee or co-trustees jointly 104 with the Trustee, or separate trustee or separate trustees, of all or any part of the Trust Fund, and to vest in such Person or Persons, in such capacity and for the benefit of the applicable Certificateholders, such title to the Trust Fund, or any part thereof, and, subject to the other provisions of this Section 9.10, such powers, duties, obligations, rights and trusts as the Servicers and the Trustee may consider necessary or desirable. If the Servicers shall not have joined in such appointment within fifteen days after the receipt by it of a request to do so, or in the case an Event of Default shall have occurred and be continuing, the Trustee alone shall have the power to make such appointment. No co-trustee or separate trustee hereunder shall be required to meet the terms of eligibility as a successor trustee under Section 9.06 and no notice to Certificateholders of the appointment of any co-trustee or separate trustee shall be required under Section 9.08. Every separate trustee and co-trustee shall, to the extent permitted by law, be appointed and act subject to the following provisions and conditions: (a) all rights, powers, duties and obligations conferred or imposed upon the Trustee, except for any obligation of the Trustee under this Agreement to advance funds on behalf of the Servicer, shall be conferred or imposed upon and exercised or performed by the Trustee and such separate trustee or co-trustee jointly (it being understood that such separate trustee or co-trustee is not authorized to act separately without the Trustee joining in such act), except to the extent that under any law of any jurisdiction in which any particular act or acts are to be performed by the Trustee (whether as Trustee hereunder or as successor to the Servicer), the Trustee shall be incompetent or unqualified to perform such act or acts, in which event such rights, powers, duties and obligations (including the holding of title to the Trust Fund or any portion thereof in any such jurisdiction) shall be exercised and performed singly by such separate trustee or co-trustee, but solely at the direction of the Trustee; (b) no trustee hereunder shall be held liable by reason of any act or omission of any other trustee hereunder; and (c) the Servicers and the Trustee acting jointly may at any time accept the resignation of or remove any separate trustee or co-trustee. Any notice, request or other writing given to the Trustee shall be deemed to have been given to each of the then separate trustees and co-trustees, as effectively as if given to each of them. Every instrument appointing any separate trustee or co-trustee shall refer to this Agreement and the conditions of this Article IX. Each separate trustee and co-trustee, upon its acceptance of the trusts conferred, shall be vested with the estates or property specified in its instrument of appointment, either jointly with the Trustee or separately, as may be provided therein, subject to all the provisions of this Agreement, specifically including every provision of this Agreement relating to the conduct of, affecting the liability of, or affording protection to, the Trustee. Every such instrument shall be filed with the Trustee and a copy thereof given to the Servicers and the Depositor. Any separate trustee or co-trustee may, at any time, constitute the Trustee its agent or attorney-in-fact, with full power and authority, to the extent not prohibited by law, to do any lawful act under or in respect of this Agreement on its behalf and in its name. If any 105 separate trustee or co-trustee shall die, become incapable of acting, resign or be removed, all of its estates, properties, rights, remedies and trusts shall vest in and be exercised by the Trustee, to the extent permitted by law, without the appointment of a new or successor trustee. SECTION 9.11 Office of the Trustee. The office of the Trustee for purposes of receipt of notices and demands is the Corporate Trust Office. SECTION 9.12 Tax Return. Each Servicer, upon request, will furnish the Trustee in a timely manner with all such information in the possession of such Servicer as may be reasonably required in connection with the preparation by the Trustee of all tax and information returns of the Trust Fund, and the Trustee shall sign such returns. Each Servicer shall indemnify the Trustee for all reasonable costs, including legal fees and expenses, related to errors in such tax returns due to errors only in information provided by such Servicer. SECTION 9.13 Periodic Filings. The Trustee shall, on behalf of the Trust, cause to be filed with the Securities and Exchange Commission any periodic reports required to be filed under the provisions of the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Securities and Exchange Commission thereunder. In connection with the preparation and filing of such periodic reports, the Depositor and each Servicer shall timely provide to the Trustee all material information requested by the Trustee and reasonably available to them which is required to be included in such reports. The Trustee shall have no liability with respect to any failure to properly prepare or file such periodic reports resulting from or relating to the Trustee's inability or failure to obtain any information not resulting from its own negligence or willful misconduct. 106 ARTICLE X TERMINATION SECTION 10.01 Termination upon Liquidation or Repurchase of all Mortgage Loans. The obligations and responsibilities of the Servicers, the Special Servicer, the Sellers, the Depositor and the Trustee created hereby with respect to the Trust Fund created hereby shall terminate upon the earlier of: (a) the repurchase by WMMSC at its election, of all Mortgage Loans and all property acquired in respect of any Mortgage Loan remaining, which repurchase right WMMSC may exercise at its sole and exclusive election as of any Distribution Date (such applicable Distribution Date being herein referred to as the "Optional Termination Date") on or after the date on which the aggregate Principal Balance of the Mortgage Loans at the time of the repurchase is less than 10% of the aggregate Principal Balance of the Mortgage Loans as of the Cut-off Date; and (b) the later of (i) twelve months after the maturity of the last Mortgage Loan remaining in the Trust Fund, (ii) the liquidation (or any advance with respect thereto) of the last Mortgage Loan remaining in the Trust Fund and the disposition of all REO Property and (iii) the distribution to Certificateholders of all amounts required to be distributed to them pursuant to this Agreement. In no event shall the trust created hereby continue beyond the earlier of (1) the expiration of 21 years from the death of the last survivor of the descendants of Mr. Joseph P. Kennedy, former Ambassador of the United States to Great Britain, living on the date of execution of this Agreement or (ii) the Distribution Date in September 2031. The Mortgage Loan Purchase Price for any such Optional Termination shall be equal to the sum of (i) 100% of the Stated Principal Balance of each Mortgage Loan in the applicable Loan Groups (other than in respect of REO Property) plus accrued and unpaid interest thereon from the date to which such interest was paid or advanced at the sum of the applicable Mortgage Rate, to but not including the Due Date in the month of the final Distribution Date (or the Net Mortgage Rate with respect to any Mortgage Loan currently serviced by the entity exercising such Optional Termination) and (ii) with respect to any REO Property, the lesser of (x) the appraised value of any REO Property as determined by the higher of two appraisals completed by two independent appraisers selected by the Depositor at the expense of the Depositor and (y) the Stated Principal Balance of each Mortgage Loan in the related Loan Groups related to any REO Property, in each case and (iii) any remaining unreimbursed Advances, Servicing Advances and Servicing Fees. The Trustee shall give notice to the Rating Agencies of election to purchase the Mortgage Loans pursuant to this Section 10.01 and of the Optional Termination Date. 107 SECTION 10.02 Procedure Upon Optional Termination. (a) In case of any Optional Termination pursuant to Section 10.01, WMMSC shall, at least twenty days prior to the date notice is to be mailed to the affected Certificateholders notify the Trustee of such Optional Termination Date and of the applicable purchase price of the Mortgage Loans to be repurchased. (b) Any repurchase of the Mortgage Loans by WMMSC shall be made on an Optional Termination Date by deposit of the applicable purchase price into the Certificate Account, as applicable, before the Distribution Date on which such repurchase is effected. Upon receipt by the Trustee of an Officer's Certificate of WMMSC certifying as to the deposit of such purchase price into the Certificate Account, the Trustee and each co-trustee and separate trustee, if any, then acting as such under this Agreement, shall, upon request and at the expense of WMMSC, execute and deliver all such instruments of transfer or assignment delivered to the Trustee by WMMSC, in each case without recourse, representation or warranty as shall be reasonably requested by WMMSC, to vest title in WMMSC in the Mortgage Loans so repurchased and shall transfer or deliver to WMMSC the repurchased Mortgage Loans. Any distributions on the Mortgage Loans which have been subject to an Optional Termination received by the Trustee subsequent to (or with respect to any period subsequent to) the Optional Termination Date shall be promptly remitted by it to WMMSC. (c) Notice of the Distribution Date on which a Servicer anticipates that the final distribution shall be made as a result of such Servicer's receipt of the remaining principal and interest due on the last Mortgage Loan serviced by such Servicer, shall be given promptly by such Servicer to the Trustee and, if such servicer is the sole remaining servicer of Mortgage Loans in the related Group, by the Trustee by first class mail to Holders of the affected Certificates. Such notice shall be mailed no earlier than the 15th day and not later than the 10th day preceding the Optional Termination Date or date of final distribution, as the case may be. Such notice shall specify (i) the Distribution Date upon which final distribution on the affected Certificates will be made upon presentation and surrender of such Certificates at the office or agency therein designated, (ii) the amount of such final distribution and (iii) that the Record Date otherwise applicable to such Distribution Date is not applicable, such distribution being made only upon presentation and surrender of such Certificates at the office or agency maintained for such purposes (the address of which shall be set forth in such notice). (d) In the event that any Certificateholders shall not surrender Certificates for cancellation within six months after the date specified in the above mentioned written notice, the Trustee shall give a second written notice to the remaining such Certificateholders to surrender their Certificates for cancellation and receive the final distribution with respect thereto. If within six months after the second notice all the Certificates shall not have been surrendered for cancellation, the Trustee may take appropriate steps, or may appoint an agent to take appropriate steps, to contact the remaining Certificateholders concerning surrender of their Certificates, and the cost thereof shall be paid out of the funds and other assets which remain subject to the Trust Fund. 108 SECTION 10.03 Additional Termination Requirements. (a) In the event WMMSC exercises its purchase option pursuant to Section 10.01, the Trust Fund shall be terminated in accordance with the following additional requirements, unless the Trustee has received an Opinion of Counsel to the effect that the failure to comply with the requirements of this Section will not (i) result in the imposition of taxes on a "prohibited transaction" of the REMIC, as described in Section 860F of the Code, or (ii) cause the Trust Fund to fail to qualify as a REMIC at any time that any Certificates are outstanding: (A) within 90 days prior to the final Distribution Date set forth in the notice given by WMMSC under Section 10.02, the Holder of the Class AR Certificates shall adopt a plan of complete liquidation of the REMIC; and (B) at or after the time of adoption of any such plan of complete liquidation for the Trust Fund at or prior to the final Distribution Date, the Trustee shall sell all of the assets of the Trust Fund to the Depositor for cash; provided, however, that in the event that a calendar quarter ends after the time of adoption of such a plan of complete liquidation but prior to the final Distribution Date, the Trustee shall not sell any of the assets of the Trust Fund prior to the close of that calendar quarter. (b) By its acceptance of a Class AR Certificate, the Holder thereof hereby agrees to adopt such a plan of complete liquidation and to take such other action in connection therewith as may be reasonably required to liquidate and otherwise terminate the Trust Fund. 109 ARTICLE XI MISCELLANEOUS PROVISIONS SECTION 11.01 Amendment. (a) This Agreement may be amended from time to time by the Depositor, the Servicers, the Sellers, the Special Servicer and the Trustee, without the consent of any of the Certificateholders, (i) to cure any error or ambiguity, (ii) to correct or supplement any provisions herein that may be inconsistent with any other provisions herein or in the Prospectus Supplement, (iii) to modify, eliminate or add to any of its provisions to such extent as shall be necessary or desirable to maintain the qualification of the Trust Fund as a REMIC at all times that any Certificate is outstanding or to avoid or minimize the risk of the imposition of any tax on the Trust Fund pursuant to the Code that would be a claim against the Trust Fund, provided that the Trustee has received an Opinion of Counsel to the effect that (A) such action is necessary or desirable to maintain such qualification or to avoid or minimize the risk of the imposition of any such tax and (B) such action will not adversely affect the status of the Trust Fund as a REMIC or adversely affect in any material respect the interests of any Certificateholder, (iv) in connection with the appointment of a successor servicer, to modify, eliminate or add to any of the servicing provisions, provided the Rating Agencies confirm the rating of the Certificates; or (v) to make any other provisions with respect to matters or questions arising under this Agreement that are not materially inconsistent with the provisions of this Agreement, provided that such action shall not adversely affect in any material respect the interests of any Certificateholder or cause an Adverse REMIC Event. (b) This Agreement may be amended from time to time by the Depositor, the Sellers, the Servicers, the Special Servicer and the Trustee with the consent of the Holders of Certificates evidencing, in the aggregate, not less than 66-2/3% of the Voting Rights of all the Certificates 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 the Certificates; provided, however, that no such amendment may (i) reduce in any manner the amount of, delay the timing of or change the manner in which payments received on or with respect to Mortgage Loans are required to be distributed with respect to any Certificate without the consent of the Holder of such Certificate, (ii) adversely affect in any material respect the interests of the Holders of a Class of Certificates in a manner other than as set forth in (i) above without the consent of the Holders of Certificates evidencing not less than 66-2/3% of the Voting Rights of such Class, (iii) reduce the aforesaid percentages of Voting Rights, the holders of which are required to consent to any such amendment without the consent of 100% of the Holders of Certificates of the Class affected thereby, (iv) change the percentage of the Stated 110 Principal Balance of the Mortgage Loans specified in Section 10.01(a) relating to optional termination of the Trust Fund or (v) modify the provisions of this Section 11.01. It shall not be necessary for the consent of Certificateholders under this Section to approve the particular form of any proposed amendment, but it shall be sufficient if such consent shall approve the substance thereof. The manner of obtaining such consents and of evidencing the authorization of the execution thereof by Certificateholders shall be subject to such reasonable regulations as the Trustee may prescribe. (c) Promptly after the execution of any amendment to this Agreement, the Trustee shall furnish written notification of the substance of such amendment to each Certificateholder, and the Rating Agencies. (d) Prior to the execution of any amendment to this Agreement, the Trustee shall receive and be entitled to conclusively rely on an Opinion of Counsel (at the expense of the Person seeking such amendment) stating that the execution of such amendment is authorized and permitted by this Agreement and that such amendment will not adversely affect the status of the Trust Fund as a REMIC. The Trustee may, but shall not be obligated to, enter into any such amendment which affects the Trustee's own rights, duties or immunities under this Agreement. SECTION 11.02 Recordation of Agreement; Counterparts. (a) This Agreement (other than Schedule I) 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 Mortgaged Properties are situated, and in any other appropriate public recording office or elsewhere. Such recordation, if any, shall be effected by the related Servicer at its expense on direction of the Trustee, 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 of the Trust Fund. (b) For the purpose of facilitating the recordation of this Agreement as herein provided and for other purposes, this Agreement may be executed simultaneously in any number of counterparts, each of which counterparts shall be deemed to be an original, and such counterparts shall constitute but one and the same instrument. SECTION 11.03 Governing Law. THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE SUBSTANTIVE LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED IN THE STATE OF NEW YORK AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HERETO AND THE CERTIFICATEHOLDERS SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS. SECTION 11.04 Intention of Parties. (a) It is the express intent of the Depositor, DLJMC, ABN AMRO, the Servicers, the Special Servicer and the Trustee that the conveyance by ABN AMRO of the ABN AMRO 111 Loans and the conveyance by DLJMC to the Depositor pursuant to the Assignment and Assumption Agreement and the conveyance by the Depositor to the Trustee as provided for in Section 2.01 of each of such Sellers' and Depositor's right, title and interest in and to the Mortgage Loans be, and be construed as, an absolute sale and assignment by such Sellers to the Depositor and by the Depositor to the Trustee of the Mortgage Loans for the benefit of the Certificateholders. Further, it is not intended that any conveyance be deemed to be a pledge of the Mortgage Loans by ABN AMRO or DLJMC, as applicable, to the Depositor or by the Depositor to the Trustee to secure a debt or other obligation.

All such standard hazard policies are in full force and effect and on the date of origination contained a standard mortgagee clause naming DLJMC and its successors in interest and assigns as loss payee and such clause is still in effect and all premiums due thereon have been paid. If required by the Flood Disaster Protection Act of 1973, as amended, the Mortgage Loan is covered by a flood insurance policy meeting the requirements of the current guidelines of the Federal Insurance Administration which policy conforms to Fannie Mae and Freddie Mac requirements, as well as all additional requirements set forth in Section 4.10 of the related Mortgage Loan Purchase Agreement. Such policy was issued by an insurer acceptable under Fannie Mae or Freddie Mac guidelines. The Mortgage obligates the Mortgagor thereunder to maintain all such insurance at the Mortgagor's cost and expense, and upon the Mortgagor's failure to do so, authorizes the holder of the Mortgage to maintain such insurance at the Mortgagor's cost and expense and to seek reimbursement therefor from the Mortgagor. Where required by state law or regulation, the Mortgagor has been given an opportunity to choose the carrier of the required hazard insurance, provided the policy 5 is not a "master" or "blanket" hazard insurance policy covering the common facilities of a planned unit development. The hazard insurance policy is the valid and binding obligation of the Insurer, is in full force and effect and inure to the benefit of the Depositor upon the consummation of the transactions contemplated by the Agreement. DLJMC has not engaged in, and has no knowledge of the Mortgagor's or any Originator's of Prior Servicer's having engaged in, any act or omission which would impair the coverage of any such policy, the benefits of the endorsement provided for herein, or the validity and binding effect of either, including, without limitation, no unlawful fee, commission, kickback or other unlawful compensation or value of any kind has been or will be received, retained or realized by any attorney, firm, or other person or entity, and no such unlawful items have been received, retained or realized by the DLJMC; (ix) 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 or disclosure laws applicable to the Mortgage Loan have been complied with in all material respects; (x) The Mortgage has not been satisfied, canceled or subordinated, in whole or in part, or rescinded, and the Mortgaged Property has not been released from the lien of the Mortgage, in whole or in part nor has any instrument been executed that would effect any such release, cancellation, subordination or rescission. DLJMC has not waived the performance by the Mortgagor of any action, if the Mortgagor's failure to perform such action would cause the Mortgage Loan to be in default, nor has DLJMC waived any default resulting from any action or inaction by the Mortgagor; (xi) With respect to any first lien Mortgage Loan, the related Mortgage is a valid, subsisting, enforceable and perfected first lien on the Mortgaged Property and, with respect to any second lien Mortgage Loan, the related Mortgage is a valid, subsisting, enforceable and perfected second lien on the Mortgaged Property, including for Mortgage Loans that are not Co-op Loans, all buildings on the Mortgaged Property and all installations and mechanical, electrical, plumbing, heating and air conditioning systems affixed to such buildings, and all additions, alterations and replacements made at any time with respect to the foregoing securing the Mortgage Note's original principal balance. The Mortgage and the Mortgage Note do not contain any evidence of any security interest or other interest or right thereto. Such lien is free and clear of all adverse claims, liens and encumbrances having priority over the first or second lien, as applicable, of the Mortgage subject only to (1) with respect to any second lien Mortgage Loan, the related First Lien, (2) the lien of non-delinquent current real property taxes and assessments not yet due and payable, (3) covenants, conditions and restrictions, rights of way, easements and other matters of the public record as of the date of recording which are acceptable to mortgage lending institutions generally and either (A) which are referred to or otherwise considered in the appraisal made for the originator of the Mortgage Loan, or (B) which do not adversely affect the appraised value of the Mortgaged Property as set forth in such appraisal, and (4) other matters to which like properties are commonly subject which do not materially interfere with the benefits of the security intended to be provided by the Mortgage or the use, enjoyment, value or marketability of the related Mortgaged 6 Property. Any security agreement, chattel mortgage or equivalent document related to and delivered in connection with the Mortgage Loan establishes and creates (1) with respect to any first lien Mortgage Loan, a valid, subsisting, enforceable and perfected first lien and first priority security interest and (2) with respect to any second lien Mortgage Loan, a valid, subsisting, enforceable and perfected second lien and second priority security interest, in each case, on the property described therein, and DLJMC has the full right to sell and assign the same to the Depositor. (xii) The Mortgage Note and the related Mortgage are original and genuine and each is the legal, valid and binding obligation of the maker thereof, enforceable in all respects in accordance with its terms subject to bankruptcy, insolvency and other laws of general application affecting the rights of creditors and DLJMC has taken all action necessary to transfer such rights of enforceability to the depositor. All parties to the Mortgage Note and the Mortgage had the legal capacity to enter into the Mortgage Loan and to execute and deliver the Mortgage Note and the Mortgage. The Mortgage Note and the Mortgage have been duly and properly executed by such parties. No fraud, error, omission, misrepresentation, negligence or similar occurrence with respect to a Mortgage Loan has taken place on the part of DLJMC or the Mortgagor, or, on the part of any other party involved in the origination of the Mortgage Loan. Except to the extent the Mortgage Loan is subject to completion escrows which have been disclosed to and acknowledged by the Depositor and which meet the requirements of DLJMC's Underwriting Standards, and as to which a completed FNMA form 442 has been delivered to the Depositor within sixty (60) days after the Closing Date, the proceeds of the Mortgage Loan have been fully disbursed and there is no requirement for future advances thereunder, and any and all requirements as to completion of any on-site or off-site improvements and as to disbursements of any escrow funds therefor have been complied with. All costs, fees and expenses incurred in making or closing the Mortgage Loan and the recording of the Mortgage were paid or are in the process of being paid, and the Mortgagor is not entitled to any refund of any amounts paid or due under the Mortgage Note or Mortgage; (xiii) DLJMC or its affiliate is the sole owner of record and holder of the Mortgage Loan and the indebtedness evidenced by the Mortgage Note, except for the assignments of mortgage which have been sent for recording, and upon recordation the Depositor or its designee will be the owner of record of the Mortgage and the indebtedness evidenced by the Mortgage Note, and upon the sale of the Mortgage Loan to the Depositor, the Servicer will retain the Mortgage File or any part thereof with respect thereto not delivered to the Depositor or the Depositor's designee in trust only for the purpose of servicing and supervising the servicing of the Mortgage Loan. Immediately prior to the transfer and assignment to the Depositor on the Closing Date, the Mortgage Loan, including the Mortgage Note and the Mortgage, were not subject to an assignment or pledge, and DLJMC had good and marketable title to and was the sole owner thereof and had full right to transfer and sell the Mortgage Loan to the Depositor free and clear of any encumbrance, equity, lien, pledge, charge, claim or security interest and has the full right and authority subject to no interest or participation of, or agreement with, any other party, to sell and assign the Mortgage Loan pursuant to this Agreement and following the sale of the Mortgage Loan, the Depositor will own such Mortgage Loan free and clear of any encumbrance, equity, participation interest, lien, pledge, charge, claim or security 7 interest. DLJMC intends to relinquish all rights to possess, control and monitor the Mortgage Loan, except for the purposes of servicing the Mortgage Loan as set forth in this Agreement; (xiv) Each Mortgage Loan that is not a Co-op Loan is covered by an ALTA lender's title insurance policy or other generally acceptable form of policy or insurance acceptable to Fannie Mae or Freddie Mac, issued by a title insurer acceptable to Fannie Mae or Freddie Mac and qualified to do business in the jurisdiction where the Mortgaged Property is located, insuring (subject to the exceptions contained in (xi)(1), (2), (3) and (4) above) DLJMC, its successors and assigns, as to the first or second, as applicable, priority lien of the Mortgage in the original principal amount of the Mortgage Loan. Where required by applicable state law or regulation, the Mortgagor has been given the opportunity to choose the carrier of the required mortgage title insurance. DLJMC, its successors and assigns, are the sole insureds of such lender's title insurance policy, such title insurance policy has been duly and validly endorsed to the Depositor or the assignment to the Depositor of DLJMC's interest therein does not require the consent of or notification to the insurer 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 and the related Mortgage Loan Purchase Agreement. No claims have been made under such lender's title insurance policy, and no prior holder of the related Mortgage, including DLJMC, has done, by act or omission, anything which would impair the coverage of such lender's title insurance policy including without limitation, no unlawful fee, commission, kickback or other unlawful compensation or value of any kind has been or will be received, retained or realized by any attorney, firm or other person or entity, and no such unlawful items have been received, retained or realized by DLJMC; (xv) There is no default, breach, violation or event of acceleration existing under the Mortgage or the related Mortgage Note and no event which, with the passage of time or with notice and the expiration of any grace or cure period, would constitute a default, breach, violation or event permitting acceleration; and neither DLJMC nor any prior mortgagee has waived any default, breach, violation or event permitting acceleration. With respect to each second lien Mortgage Loan, (i) the First Lien is in full force and effect, (ii) there is no default, breach, violation or event of acceleration existing under such prior mortgage or the related mortgage note, (iii) 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 thereunder, and either (A) the prior mortgage contains a provision which allows or (B) applicable law requires, the mortgagee under the second lien Mortgage Loan to receive notice of, and affords such mortgagee an opportunity to cure any default by payment in full or otherwise under the prior mortgage; (xvi) There are no mechanics' or similar liens or claims which have been filed for work, labor or material (and no rights are outstanding that under law could give rise to such liens) affecting the related Mortgaged Property which are or may be liens prior to or equal to the lien of the related Mortgage; (xvii) All improvements subject to the Mortgage which were considered in determining the appraised value of the Mortgaged Property lie wholly within the boundaries and building 8 restriction lines of the Mortgaged Property (and wholly within the project with respect to a condominium unit) and no improvements on adjoining properties encroach upon the Mortgaged Property except those which are insured against by the title insurance policy referred to in clause (xiv) above and all improvements on the property comply with all applicable zoning and subdivision laws and ordinances; (xviii) The Mortgage Loan was originated by or for DLJMC. The Mortgage Loan complies with all the terms, conditions and requirements of DLJMC's Underwriting Standards in effect at the time of origination of such Mortgage Loan. The Mortgage Notes and Mortgages (exclusive of any riders) are on forms generally acceptable to Fannie Mae or Freddie Mac. DLJMC is currently selling loans to Fannie Mae and/or Freddie Mac which are the same document forms as the Mortgage Notes and Mortgages (inclusive of any riders). The Mortgage Loan bears interest at the Mortgage Interest Rate set forth in the Mortgage Loan Schedule, and Monthly Payments under the Mortgage Note are due and payable on the first day of each month. The Mortgage contains the usual and enforceable provisions of the originator at the time of origination for the acceleration of the payment of the unpaid principal amount of the Mortgage Loan if the related Mortgaged Property is sold without the prior consent of the mortgagee thereunder; (xix) The Mortgaged Property is not subject to any material damage by waste, fire, earthquake, windstorm, flood or other casualty. At origination of the Mortgage Loan there was, and there currently is, no proceeding pending for the total or partial condemnation of the Mortgaged Property. There have not been any condemnation proceedings with respect to the Mortgaged Property and there are no such proceedings scheduled to commence at a future date; (xx) The related Mortgage contains customary and enforceable provisions such as to render the rights and remedies of the holder thereof adequate for the realization against the Mortgaged Property of the benefits of the security provided thereby including, (1) in the case of a Mortgage designated as a deed of trust, by trustee's sale, and (2) otherwise by judicial foreclosure. There is no homestead or other exemption available to the Mortgagor which would interfere with the right to sell the Mortgaged Property at a trustee's sale or the right to foreclose the Mortgage subject to applicable federal and state laws and judicial precedent with respect to bankruptcy and right of redemption; (xxi) If the Mortgage constitutes a deed of trust, a trustee, authorized and duly qualified if required under applicable law to act as such, has been properly designated and currently so serves and is named in the Mortgage, and no fees or expenses, except as may be required by local law, are or will become payable by the Depositor to the trustee under the deed of trust, except in connection with a trustee's sale or attempted sale after default by the Mortgagor; (xxii) The Mortgage File contains an appraisal of the related Mortgaged Property signed prior to the final approval of the mortgage loan application by a Qualified Appraiser, approved by DLJMC who had no interest, direct or indirect, in the Mortgaged Property or in any loan made on the security thereof, and whose compensation is not affected by the approval or disapproval of the Mortgage Loan, and the appraisal and appraiser both 9 satisfy the requirements of Fannie Mae or Freddie Mac and Title XI of the Federal Institutions Reform, Recovery, and Enforcement Act of 1989 and the regulations promulgated thereunder, all as in effect on the date the Mortgage Loan was originated.

Each Mortgage Note requires a monthly payment which is sufficient to fully amortize the original principal balance over the original term thereof and to pay interest at the related Mortgage Interest Rate provided, however, in the case of a balloon Mortgage Loan, the Mortgage Loan matures at least five (5) years after the first payment date thereby requiring a final payment of the outstanding principal balance prior to the full amortization of the Mortgage Loan. No Mortgage Loan contains terms or provisions which would result in negative amortization. (xxix) Except for Mortgage Loans underwritten in accordance with the Lender Paid Mortgage Insurance Policy Program, if a Mortgage Loan has an LTV greater than 80%, the excess of the principal balance of the Mortgage Loan over 80% of the Appraised Value, with 10 respect to a Refinanced Mortgage Loan, or the lesser of the Appraised Value or the purchase price of the Mortgaged Property, with respect to a purchase money Mortgage Loan, is and will be insured as to payment defaults by a Primary Mortgage Insurance Policy issued by a Qualified Insurer. All provisions of such Primary Mortgage Insurance Policy have been and are being complied with, such policy is in full force and effect, and all premiums due thereunder have been paid. No action, inaction, or event has occurred and no state of facts exists that has, or will result in the exclusion from, denial of, or defense to coverage. Any Mortgage Loan subject to a Primary Mortgage Insurance Policy obligates the Mortgagor thereunder to maintain the Primary Mortgage Insurance Policy and to pay all premiums and charges in connection therewith. The mortgage interest rate for the Mortgage Loan as set forth on the Mortgage Loan Schedule is net of any such insurance premium; (xxx) The Assignment of Mortgage is in recordable form and is acceptable for recording under the laws of the jurisdiction in which the Mortgaged Property is located; (xxxi) As to Mortgage Loans that are not Co-op Loans and that are not secured by an interest in a leasehold estate, the Mortgaged Property is located in the state identified in the Mortgage Loan Schedule and consists of a single parcel of real property with a detached single family residence erected thereon, or a townhouse, or a two-to four-family dwelling, or an individual condominium unit in a condominium project, or an individual unit in a planned unit development or a de minimis planned unit development, provided, however, that no residence or dwelling is a single parcel of real property with a cooperative housing corporation erected thereon, or a mobile home. As of the date of origination, no portion of the Mortgaged Property was used for commercial purposes, and since the date or origination no portion of the Mortgaged Property has been used for commercial purposes except for incidental uses which are in accordance with Fannie Mae or Freddie Mac guidelines; (xxxii) Principal payments on the Mortgage Loan commenced no more than sixty (60) days after the funds were disbursed in connection with the Mortgage Loan. The Mortgage Note is payable on the first day of each month in equal monthly installments of principal and interest, with interest calculated and payable in arrears, sufficient to amortize the Mortgage Loan fully by the stated maturity date, over an original term of not more than thirty years from commencement of amortization than forty years from commencement of amortization with respect to each Adjustable Rate Mortgage Loan; provided, however, in the case of a balloon Mortgage Loan, the Mortgage Loan mature at least five (5) years after the first payment date thereby requiring a final payment of the outstanding principal balance prior to the full amortization of the Mortgage Loan; (xxxiii) Certain Mortgage Loans as specified on Schedule IA may contain a Prepayment Penalty in an amount specified in the related Mortgage Note or Mortgage.

There are no liens against or security interest in the cooperative shares relating to each Co-op Loan (except for unpaid maintenance, assessments and other amounts owed to the related cooperative which individually or in the aggregate will not have a material adverse effect on such Co-op Loan), which have priority over DLJMC's security interest in such cooperative shares; 12 (xlii) With respect to each Co-op Loan, a search for filings of financing statements has been made by a company competent to make the same, which company is acceptable to Fannie Mae and qualified to do business in the jurisdiction where the cooperative unit is located, and such search has not found anything which would materially and adversely affect the Co-op Loan; (xliii) With respect to each Co-op Loan, the related cooperative corporation that owns title to the related cooperative apartment building is a "cooperative housing corporation" within the meaning of Section 216 of the Code, and is in material compliance with applicable federal, state and local laws which, if not complied with, could have a material adverse effect on the Mortgaged Property; (xliv) With respect to each Co-op Loan, there is no prohibition against pledging the shares of the cooperative corporation or assigning the Co-op Lease; (xlv) The Mortgage Loan was originated by a mortgagee approved by the Secretary of Housing and Urban Development pursuant to sections 203 and 211 of the National Housing Act, a savings and loan association, a savings bank, a commercial bank, credit union, insurance company or similar institution which is supervised and examined by a federal or state authority; (xlvi) With respect to any ground lease to which a Mortgaged Property may be subject: (i) a true, correct and complete copy of the ground lease and all amendments, modifications and supplements thereto is included in the Mortgage File, and the Mortgagor is the owner of a valid and subsisting leasehold interest under such ground lease; (ii) such ground lease is in full force and effect, unmodified and not supplemented by any writing or otherwise except as contained in the Mortgage File; (iii) all rent, additional rent and other charges reserved therein have been fully paid to the extent payable as of the Closing Date; (iv) the Mortgagor enjoys the quiet and peaceful possession of the leasehold estate, subject to any sublease; (v) the Mortgagor is not in default under any of the terms of such ground lease, and there are no circumstances which, with the passage of time or the giving of notice, or both, would result in a default under such ground lease; (vi) the lessor under such ground lease is not in default under any of the terms or provisions of such ground lease on the part of the lessor to be observed or performed; (vii) the lessor under such ground lease has satisfied any repair or construction obligations due as of the Closing Date pursuant to the terms of such ground lease; (viii) the execution, delivery and performance of the Mortgage do not require the consent (other than those consents which have been obtained and are in full force and effect) under, and will not contravene any provision of or cause a default under, such ground lease; (ix) the ground lease term extends, or is automatically renewable, for at least five years beyond the maturity date of the related Mortgage Loan; and (x) the Depositor has the right to cure defaults on the ground lease; (xlvii) With respect to any broker fees collected and paid on any of the Mortgage Loans, all broker fees have been properly assessed to the borrower and no claims will arise as to broker fees that are double charged and for which the borrower would be entitled to reimbursement; 13 (xlviii) Each Mortgage Loan constitutes a qualified mortgage under Section 860G(a)(3)(A) of the Code and Treasury Regulations Section 1.860G-2(a)(1); (xlix) There does not exist on the related Mortgage Property any hazardous substances, hazardous wastes or solid wastes, as such terms are defined in the Comprehensive Environmental Response Compensation and Liability Act, the Resource Conservation and Recovery Act of 1976, or other federal, state or local environmental legislation; (l) No second lien Mortgage Loan has an LTV in excess of 100%.

With respect to each second lien Mortgage Loan, (i) the First Lien is in full force and effect, (ii) there is no default, breach, violation or event of acceleration existing under such prior mortgage or the related mortgage note, (iii) 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 thereunder, and either (A) the prior mortgage contains a provision which allows or (B) applicable law requires, the mortgagee under the second lien Mortgage Loan to receive notice of, and affords such mortgagee an opportunity to cure any default by payment in full or otherwise under the prior mortgage; (p) To the best of the Seller's knowledge, there are no mechanics' or similar liens or claims which have been filed for work, labor or material (and no rights are outstanding that under law could give rise to such liens) affecting the related Mortgaged Property which are or may be liens prior to or equal to the lien of the related Mortgage; (q) All improvements subject to the Mortgage which were considered in determining the appraised value of the Mortgaged Property lie wholly within the boundaries and building restriction lines of the Mortgaged Property (and wholly within the project with respect to a condominium unit) and no improvements on adjoining properties encroach upon the Mortgaged Property except those which are insured against by the title insurance policy referred to in clause (m) above and all improvements on the property comply with all applicable zoning and subdivision laws and ordinances; (r) The Mortgage Loan was originated by or for the Seller.

The Mortgage Loan bears interest at the Mortgage Interest Rate set forth in the Mortgage Loan Schedule, and Monthly Payments under the Mortgage Note are due and payable on the first day of each month.

Each Mortgage Note requires a monthly payment which is sufficient to fully amortize the original principal balance over the original term thereof and to pay interest at the related Mortgage Interest Rate; provided, however, in the case of a balloon Mortgage Loan, the Mortgage Loan matures at least five (5) years after the first payment date thereby requiring a final payment of the outstanding principal balance prior to the full amortization of the Mortgage Loan. No Mortgage Loan contains terms or provisions which would result in negative amortization. (cc) Except for Mortgage Loans underwritten in accordance with the Lender Paid Mortgage Insurance Policy Program, if a Mortgage Loan has an LTV greater than 80%, the excess of the principal balance of the Mortgage Loan over 75% of the Appraised Value, with respect to a Refinanced Mortgage Loan, or the lesser of the Appraised Value or the purchase price of the Mortgaged Property, with respect to a purchase money Mortgage Loan, is and will be insured as to payment defaults by a Primary Mortgage Insurance Policy issued by a Qualified Insurer. All provisions of such Primary Mortgage Insurance Policy have been and are being complied with, such policy is in full force and effect, and all premiums due thereunder have been paid. No action, inaction, or event has occurred and no state of facts exists that has, or will result in the exclusion from, denial of, or defense to coverage.

To the best of the Seller's knowledge, as of the date of origination, no portion of the Mortgaged Property was used for commercial purposes; (ff) Principal payments on the Mortgage Loan commenced no more than sixty (60) days after the funds were disbursed in connection with the Mortgage Loan. The Mortgage Note is payable on the first day of each month in equal monthly installments of principal and interest, with interest calculated and payable in arrears, sufficient to amortize the Mortgage Loan fully by the stated maturity date, over an original term of not more than thirty years from 22 commencement of amortization with respect to each Fixed Rate Mortgage Loan or an original term of not more than forty years from commencement of amortization with respect to each Adjustable Rate Mortgage Loan; provided, however, in the case of a balloon Mortgage Loan, the Mortgage Loan matures at least five (5) years after the first payment date thereby requiring a final payment of the outstanding principal balance prior to the full amortization of the Mortgage Loan; (gg) With respect to each Mortgage Loan that contains a Prepayment Penalty, such Prepayment Penalty is enforceable and will be enforced by the Seller, and such Prepayment Penalty is permitted pursuant to federal, state and local law.

There are no liens against or security interest in the cooperative shares relating to each Co-op Loan (except for unpaid maintenance, assessments and other amounts owed to the related cooperative which individually or in the aggregate will not have a material adverse effect on such Co-op Loan), which have priority over the Seller's security interest in such cooperative shares;
