The Seller shall pay from its own funds, without any right of reimbursement therefor, the amount of any costs, liabilities and expenses incurred by the Trust Estate by reason of the failure of the Seller to cause to be delivered to the Trustee within one (1) year following the Closing Date any original Mortgage or assignment of a Mortgage (except with respect to any Mortgage recorded in the name of MERS) not delivered to the Trustee on the Closing Date. In lieu of recording an assignment of any Mortgage the Seller may, to the extent set forth in the applicable Servicing Agreement, deliver or cause to be delivered to the Trustee the assignment of the Mortgage Loan from the Seller to the Trustee in a form suitable for recordation, if (i) with respect to a particular state the Trustee has received an Opinion of Counsel acceptable to it that such recording is not required to make the assignment effective against the parties to the Mortgage or subsequent purchasers or encumbrancers of the Mortgaged Property or (ii) the Seller has been advised by each Rating Agency that non-recordation in a state will not result in a reduction of the rating assigned by that Rating Agency at the time of the initial issuance of the Certificates. In the event that the Master Servicer receives notice that recording is required to protect the right, title and interest of the Trustee in and to any such Mortgage Loan for which recordation of an assignment has not previously been required, the Master Servicer shall promptly notify the Trustee and the Trustee shall within five Business Days (or such other reasonable period of time mutually agreed upon by the Master Servicer and the Trustee) of its receipt of such notice deliver each previously unrecorded assignment to the related Servicer for recordation. SECTION 2.02 ACCEPTANCE BY TRUSTEE. The Trustee, acknowledges receipt of the Mortgage Notes, the Mortgages, the assignments (unless the related Mortgage has been registered in the name of MERS or its designee) and other documents required to be delivered on the Closing Date pursuant to Section 2.01 above and declares that it holds and will hold such documents and the other documents constituting a part of the Owner Mortgage Loan Files delivered to it in trust, upon the trusts herein set forth, for the use and benefit of all present and future Certificateholders. The Trustee agrees, for the benefit of Certificateholders, to review each Owner Mortgage Loan File within 45 days after execution of this Agreement in order to ascertain that all required documents set forth in Section 2.01 have been executed and received and appear regular on their face, and that such documents relate to the Mortgage Loans identified in the Mortgage Loan Schedule, and in so doing the Trustee may rely on the purported due execution and genuineness of any such document and on the purported genuineness of any signature thereon. If within such 45 day period the Trustee finds any document constituting a part of an Owner Mortgage Loan File not to have been executed or received or to be unrelated to the Mortgage Loans identified in the Mortgage Loan Schedule or not to appear regular on its face, the Trustee shall promptly (and in no event more than 30 days after the discovery of such defect) notify the Seller, which shall have a period of 60 days after the date of such notice within which to correct or cure any such defect. The Seller hereby covenants and agrees that, if any material defect is not so corrected or cured, the Seller will, not later than 60 days after the Trustee's notice to it referred to above respecting such defect, either (i) repurchase the related Mortgage Loan or any property acquired in respect thereof from the Trust Estate at a price equal to (a) 100% of the unpaid principal balance of such Mortgage Loan plus (b) accrued interest at the Mortgage Interest Rate, less any Fixed Retained Yield, through the last day of the month in which such repurchase takes place or (ii) if within two years of the Startup Day, or such other period permitted by the REMIC Provisions, substitute for any Mortgage Loan to which such material defect relates, a new mortgage loan (a "Substitute Mortgage Loan") having such characteristics so that the representations and warranties of the Seller set forth in Section 2.03(b) hereof (other than Section 2.03(b)(i)) would not have been incorrect had such Substitute Mortgage Loan originally been a Mortgage Loan. In no event shall any Substitute Mortgage Loan have an unpaid principal balance, as of the date of substitution, greater than the Scheduled Principal Balance (reduced by the scheduled payment of principal due on the Due Date in the month of substitution) of the Mortgage Loan for which it is substituted. In addition, such Substitute Mortgage Loan shall have a Loan-to-Value Ratio less than or equal to and a Mortgage Interest Rate equal to that of the Mortgage Loan for which it is substituted. In the case of a repurchased Mortgage Loan or property, the purchase price shall be deposited by the Seller in the Certificate Account maintained by the Master Servicer pursuant to Section 3.01. In the case of a Substitute Mortgage Loan, the Owner Mortgage Loan File relating thereto shall be delivered to the Trustee and the Substitution Principal Amount, together with (i) interest on such Substitution Principal Amount at the applicable Net Mortgage Interest Rate to the following Due Date of such Mortgage Loan which is being substituted for and (ii) an amount equal to the aggregate amount of unreimbursed Periodic Advances in respect of interest previously made by the Servicer, the Master Servicer or the Trustee with respect to such Mortgage Loan, shall be deposited in the Certificate Account. The Monthly Payment on the Substitute Mortgage Loan for the Due Date in the month of substitution shall not be part of the Trust Estate. Upon receipt by the Trustee of written notification of any such deposit signed by an officer of the Seller, or the new Owner Mortgage Loan File, as the case may be, the Trustee shall release to the Seller the related Owner Mortgage Loan File and shall execute and deliver such instrument of transfer or assignment (or, in the case of a Mortgage Loan registered in the name of MERS or its designee, the Master Servicer shall take all necessary action to reflect such assignment on the records of MERS), in each case without recourse, as shall be necessary to vest in the Seller legal and beneficial ownership of such substituted or repurchased Mortgage Loan or property. It is understood and agreed that the obligation of the Seller to substitute a new Mortgage Loan for or repurchase any Mortgage Loan or property as to which such a material defect in a constituent document exists shall constitute the sole remedy respecting such defect available to the Certificateholders or the Trustee on behalf of the Certificateholders. The failure of the Trustee to give any notice contemplated herein within forty-five (45) days after the execution of this Agreement shall not affect or relieve the Seller's obligation to repurchase any Mortgage Loan pursuant to this Section 2.02. The Trustee may, concurrently with the execution and delivery hereof or at any time thereafter, enter into a Custodial Agreement substantially in the form of Exhibit E hereto pursuant to which the Trustee appoints a Custodian to hold the Mortgage Notes, the Mortgages, the assignments and other documents related to the Mortgage Loans received by the Trustee, in trust for the benefit of all present and future Certificateholders, which may provide, among other things, that the Custodian shall conduct the review of such documents required under the first paragraph of this Section 2.02.

It is understood and agreed that the obligation of the Seller to repurchase or substitute for any Mortgage Loan or property as to which such a breach has occurred and is continuing shall constitute the sole remedy respecting such breach available to Certificateholders or the Trustee on behalf of Certificateholders, and such obligation shall survive until termination of the Trust Estate hereunder. SECTION 2.04 EXECUTION AND DELIVERY OF CERTIFICATES.

Any amounts deposited in the Certificate Account prior to the Distribution Date shall be invested for the account of the Master Servicer and any investment income thereon shall be additional compensation to the Master Servicer for services rendered under this Agreement. The amount of any losses incurred in respect of any such investments shall be deposited in the Certificate Account by the Master Servicer out of its own funds immediately as realized.

(b) The Master Servicer shall keep and maintain separate accounting, on a Mortgage Loan by Mortgage Loan basis, for the purpose of justifying any payment to and withdrawal from the Certificate Account. SECTION 3.03 ADVANCES BY MASTER SERVICER AND TRUSTEE. (a) In the event an Other Servicer fails to make any required Periodic Advances of principal and interest on a Mortgage Loan as required by the related Other Servicing Agreement prior to the Distribution Date occurring in the month during which such Periodic Advance is due, the Master Servicer shall make Periodic Advances to the extent provided hereby. In addition, if under the terms of an Other Servicing Agreement, the applicable Servicer is not required to make Periodic Advances on a Mortgage Loan or REO Mortgage Loan through the liquidation of such Mortgage Loan or REO Mortgage Loan, the Master Servicer to the extent provided hereby shall make the Periodic Advances thereon during the period the Servicer is not obligated to do so. In the event WFHM fails to make any required Periodic Advances of principal and interest on a Mortgage Loan as required by the WFHM Servicing Agreement prior to the Distribution Date occurring in the month during which such Periodic Advance is due, the Trustee shall, to the extent required by Section 8.15, make such Periodic Advance to the extent provided hereby, provided that the Trustee has previously received the certificate of the Master Servicer described in the following sentence. The Master Servicer shall certify to the Trustee with respect to any such Distribution Date (i) the amount of Periodic Advances required of WFHM or such Other Servicer, as the case may be, (ii) the amount actually advanced by WFHM or such Other Servicer, (iii) the amount that the Trustee or Master Servicer is required to advance hereunder, including any amount the Master Servicer is required to advance pursuant to the second sentence of this Section 3.03(a), and (iv) whether the Master Servicer has determined that it reasonably believes that such Periodic Advance is a Nonrecoverable Advance. Amounts advanced by the Trustee or Master Servicer shall be deposited in the Certificate Account on the related Distribution Date. Notwithstanding the foregoing, neither the Master Servicer nor the Trustee will be obligated to make a Periodic Advance that it reasonably believes to be a Nonrecoverable Advance. The Trustee may conclusively rely for any determination to be made by it hereunder upon the determination of the Master Servicer as set forth in its certificate. (b) To the extent an Other Servicer fails to make an advance on account of the taxes or insurance premiums with respect to a Mortgage Loan required pursuant to the related Other Servicing Agreement, the Master Servicer shall, if the Master Servicer knows of such failure of the Servicer, advance such funds and take such steps as are necessary to pay such taxes or insurance premiums. To the extent WFHM fails to make an advance on account of the taxes or insurance premiums with respect to a Mortgage Loan required pursuant to the WFHM Servicing Agreement, the Master Servicer shall, if the Master Servicer knows of such failure of WFHM, certify to the Trustee that such failure has occurred. Upon receipt of such certification, the Trustee shall advance such funds and take such steps as are necessary to pay such taxes or insurance premiums. (c) The Master Servicer and the Trustee shall each be entitled to be reimbursed from the Certificate Account for any Periodic Advance made by it under Section 3.03(a) to the extent described in Section 3.02(a)(i) and (a)(ii). The Master Servicer and the Trustee shall be entitled to be reimbursed pursuant to Section 3.02(a)(v) for any advance by it pursuant to Section 3.03(b). The Master Servicer shall diligently pursue restoration of such amount to the Certificate Account from the related Servicer. The Master Servicer shall, to the extent it has not already done so, upon the request of the Trustee, withdraw from the Certificate Account and remit to the Trustee any amounts to which the Trustee is entitled as reimbursement pursuant to Section 3.02 (a)(i), (ii) and (v). (d) Except as provided in Section 3.03(a) and (b), neither the Master Servicer nor the Trustee shall be required to pay or advance any amount which any Servicer was required, but failed, to deposit in the Certificate Account. SECTION 3.04 TRUSTEE TO COOPERATE; RELEASE OF OWNER MORTGAGE LOAN FILES. Upon the receipt by the Master Servicer of a Request for Release in connection with the deposit by a Servicer into the Certificate Account of the proceeds from a Liquidated Loan or of a Prepayment in Full, the Master Servicer shall confirm to the Trustee that all amounts required to be remitted to the Certificate Account in connection with such Mortgage Loan have been so deposited, and shall deliver such Request for Release to the Trustee. The Trustee shall, within five Business Days of its receipt of such a Request for Release, release the related Owner Mortgage Loan File to the Master Servicer or such Servicer, as requested by the Master Servicer. No expenses incurred in connection with any instrument of satisfaction or deed of reconveyance shall be chargeable to the Certificate Account. From time to time and as appropriate for the servicing or foreclosure of any Mortgage Loan, including but not limited to, collection under any insurance policies, or to effect a partial release of any Mortgaged Property from the lien of the Mortgage, the Servicer of such Mortgage Loan shall deliver to the Master Servicer a Request for Release. Upon the Master Servicer's receipt of any such Request for Release, the Master Servicer shall promptly forward such request to the Trustee and the Trustee shall, within five Business Days, release the related Owner Mortgage Loan File to the Master Servicer or such Servicer, as requested by the Master Servicer. Any such Request for Release shall obligate the Master Servicer or such Servicer, as the case may be, to return each and every document previously requested from the Owner Mortgage Loan File to the Trustee by the twenty-first day following the release thereof, unless (i) the Mortgage Loan has been liquidated and the Liquidation Proceeds relating to the Mortgage Loan have been deposited in the Certificate Account or (ii) the Owner Mortgage Loan File or such document has been delivered to an attorney, or to a public trustee or other public official as required by law, for purposes of initiating or pursuing legal action or other proceedings for the foreclosure of the Mortgaged Property either judicially or non-judicially, and the Master Servicer has delivered to the Trustee a certificate of the Master Servicer or such Servicer certifying as to the name and address of the Person to which such Owner Mortgage Loan File or such document was delivered and the purpose or purposes of such delivery. Upon receipt of an Officer's Certificate of the Master Servicer or such Servicer stating that such Mortgage Loan was liquidated and that all amounts received or to be received in connection with such liquidation which are required to be deposited into the Certificate Account have been so deposited, or that such Mortgage Loan has become an REO Mortgage Loan, the Request for Release shall be released by the Trustee to the Master Servicer or such Servicer, as appropriate. Upon written certification of the Master Servicer or the Servicer pursuant to clause (ii) of the preceding paragraph, the Trustee shall execute and deliver to the Master Servicer or such Servicer, as directed by the Master Servicer, court pleadings, requests for trustee's sale or other documents necessary to the foreclosure or trustee's sale in respect of a Mortgaged Property or to any legal action brought to obtain judgment against any Mortgagor on the Mortgage Note or Mortgage or to obtain a deficiency judgment, or to enforce any other remedies or rights provided by the Mortgage Note or Mortgage or otherwise available at law or in equity. Each such certification shall include a request that such pleadings or documents be executed by the Trustee and a statement as to the reason such documents or pleadings are required and that the execution and delivery thereof by the Trustee will not invalidate or otherwise affect the lien of the Mortgage, except for the termination of such a lien upon completion of the foreclosure proceeding or trustee's sale. SECTION 3.05 REPORTS TO THE TRUSTEE; ANNUAL COMPLIANCE STATEMENTS. (a) Not later than 15 days after each Distribution Date, the Master Servicer shall deliver to the Trustee a statement setting forth the status of the Certificate Account as of the close of business on such Distribution Date stating that all distributions required to be made by the Master Servicer under this Agreement have been made (or, if any required distribution has not been made by the Master Servicer, specifying the nature and status thereof) and showing, for the period covered by such statement, the aggregate amount of deposits into and withdrawals from such account for each category of deposit and withdrawal specified in Sections 3.01 and 3.02. Such statement may be in the form of the then current Fannie Mae monthly accounting report for its Guaranteed Mortgage Pass-Through Program with appropriate additions and changes, and shall also include information as to the aggregate unpaid principal balance of all of the Mortgage Loans as of the close of business as of the last day of the calendar month immediately preceding such Distribution Date. Copies of such statement shall be provided by the Trustee to any Certificateholder upon written request, provided such statement is delivered, or caused to be delivered, by the Master Servicer to the Trustee. (b) The Master Servicer shall deliver to the Trustee on or before April 30 of each year, a certificate signed by an officer of the Master Servicer, certifying that (i) such officer has reviewed the activities of the Master Servicer during the preceding calendar year or portion thereof and its performance under this agreement and (ii) to the best of such officer's knowledge, based on such review, the Master Servicer has performed and fulfilled its duties, responsibilities and obligations under this agreement in all material respects throughout such year, or, if there has been a default in the fulfillment of any such duties, responsibilities or obligations, specifying each such default known to such officer and the nature and status thereof, and, (iii) (A) the Master Servicer has received from each Servicer any financial statements, officer's certificates, accountant's statements or other information required to be provided to the Master Servicer pursuant to the related Servicing Agreement and (B) to the best of such officer's knowledge, based on a review of the information provided to the Master Servicer by each Servicer as described in (iii)(A) above, each Servicer has performed and fulfilled its duties, responsibilities and obligations under the related Servicing Agreement in all material respects throughout such year, or, if there has been a default in the fulfillment of any such duties, responsibilities or obligations, specifying each such default known to such officer and the nature and status thereof. Copies of such officers' certificate shall be provided by the Trustee to any Certificateholder upon written request provided such certificate is delivered, or caused to be delivered, by the Master Servicer to the Trustee. SECTION 3.06 TITLE, MANAGEMENT AND DISPOSITION OF ANY REO MORTGAGE LOAN. The Master Servicer shall ensure that each REO Mortgage Loan is administered by the related Servicer at all times so that it qualifies as "foreclosure property" under the REMIC Provisions and that it does not earn any "net income from foreclosure property" which is subject to tax under the REMIC Provisions. In the event that a Servicer is unable to dispose of any REO Mortgage Loan within the period mandated by each of the Servicing Agreements, the Master Servicer shall monitor such Servicer to verify that such REO Mortgage Loan is auctioned to the highest bidder within the period so specified. In the event of any such sale of a REO Mortgage Loan, the Trustee shall, at the written request of the Master Servicer and upon being supported with appropriate forms therefor, within five Business Days of the deposit by the Master Servicer of the proceeds of such sale or auction into the Certificate Account, release or cause to be released to the entity identified by the Master Servicer the related Owner Mortgage Loan File and Servicer Mortgage Loan File and shall execute and deliver such instruments of transfer or assignment, in each case without recourse, as shall be necessary to vest in the auction purchaser title to the REO Mortgage Loan and the Trustee shall have no further responsibility with regard to such Owner Mortgage Loan File or Servicer Mortgage Loan File. Neither the Trustee, the Master Servicer nor any Servicer, acting on behalf of the Trust Estate, shall provide financing from the Trust Estate to any purchaser of an REO Mortgage Loan. SECTION 3.07 AMENDMENTS TO SERVICING AGREEMENTS, MODIFICATION OF STANDARD PROVISIONS. (a) Subject to the prior written consent of the Trustee pursuant to Section 3.07(b), the Master Servicer from time to time may, to the extent permitted by the applicable Servicing Agreement, make such modifications and amendments to such Servicing Agreement as the Master Servicer deems necessary or appropriate to confirm or carry out more fully the intent and purpose of such Servicing Agreement and the duties, responsibilities and obligations to be performed by the Servicer thereunder. Such modifications may only be made if they are consistent with the REMIC Provisions, as evidenced by an Opinion of Counsel. Prior to the issuance of any modification or amendment, the Master Servicer shall deliver to the Trustee such Opinion of Counsel and an Officer's Certificate setting forth (i) the provision that is to be modified or amended, (ii) the modification or amendment that the Master Servicer desires to issue and (iii) the reason or reasons for such proposed amendment or modification. (b) The Trustee shall consent to any amendment or supplement to a Servicing Agreement proposed by the Master Servicer pursuant to Section 3.07(a), which consent and amendment shall not require the consent of any Certificateholder if it is (i) for the purpose of curing any mistake or ambiguity or to further effect or protect the rights of the Certificateholders or (ii) for any other purpose, provided such amendment or supplement for such other purpose cannot reasonably be expected to adversely affect Certificateholders. The lack of reasonable expectation of an adverse effect on Certificateholders may be established through the delivery to the Trustee of (i) an Opinion of Counsel to such effect or (ii) written notification from each Rating Agency to the effect that such amendment or supplement will not result in reduction of the current rating assigned by that Rating Agency to the Certificates. Notwithstanding the two immediately preceding sentences, the Trustee may, in its discretion, decline to enter into or consent to any such supplement or amendment if its own rights, duties or immunities shall be adversely affected. (c) (i) Notwithstanding anything to the contrary in this Section 3.07, the Master Servicer from time to time may, without the consent of any Certificateholder, or the Trustee, enter into an amendment (A) to an Other Servicing Agreement for the purpose of (i) eliminating or reducing Month End Interest and (ii) providing for the remittance of Full Unscheduled Principal Receipts by the applicable Servicer to the Master Servicer not later than the 24th day of each month (or if such day is not a Business Day, on the previous Business Day) or (B) to the WFHM Servicing Agreement for the purpose of changing the applicable Remittance Date to the 18th day of each month (or if such day is not a Business Day, on the previous Business Day). (ii) The Master Servicer may direct WFHM to enter into an amendment to the WFHM Servicing Agreement for the purposes described in Sections 3.07(c)(i)(B) and 10.01(b)(iii). SECTION 3.08 OVERSIGHT OF SERVICING. The Master Servicer shall supervise, monitor and oversee the servicing of the Mortgage Loans by each Servicer and the performance by each Servicer of all services, duties, responsibilities and obligations (including the obligation to maintain an Errors and Omissions Policy and Fidelity Bond) that are to be observed or performed by the Servicer under its respective Servicing Agreement. In performing its obligations hereunder, the Master Servicer shall act in a manner consistent with Accepted Master Servicing Practices and with the Trustee's and the Certificateholders' reliance on the Master Servicer, and in a manner consistent with the terms and provisions of any insurance policy required to be maintained by the Master Servicer or any Servicer pursuant to this Agreement or any Servicing Agreement. The Master Servicer acknowledges that prior to taking certain actions required to service the Mortgage Loans, each Servicing Agreement provides that the Servicer thereunder must notify, consult with, obtain the consent of or otherwise follow the instructions of the Master Servicer. The Master Servicer is also given authority to waive compliance by a Servicer with certain provisions of its Servicing Agreement. In each such instance, the Master Servicer shall promptly instruct such Servicer or otherwise respond to such Servicer's request. In no event will the Master Servicer instruct such Servicer to take any action, give any consent to action by such Servicer or waive compliance by such Servicer with any provision of such Servicer's Servicing Agreement if any resulting action or failure to act would be inconsistent with the requirements of the Rating Agencies that rated the Certificates or would otherwise have an adverse effect on the Certificateholders. Any such action or failure to act shall be deemed to have an adverse effect on the Certificateholders if such action or failure to act either results in (i) the downgrading of the rating assigned by any Rating Agency to the Certificates, (ii) the loss by the Trust Estate of REMIC status for federal income tax purposes or (iii) the imposition of any Prohibited Transaction Tax or any federal taxes on the REMIC or the Trust Estate. The Master Servicer shall have full power and authority in its sole discretion to take any action with respect to the Trust Estate as may be necessary or advisable to avoid the circumstances specified including clause (ii) or (iii) of the preceding sentence. For the purposes of determining whether any modification of a Mortgage Loan shall be permitted by the Master Servicer, such modification shall be construed as a substitution of the modified Mortgage Loan for the Mortgage Loan originally deposited in the Trust Estate if it would be a "significant modification" within the meaning of Section 1.860G-2(b) of the regulations of the U.S. Department of the Treasury. No modification shall be approved unless (i) the modified Mortgage Loan would qualify as a Substitute Mortgage Loan under Section 2.02 and (ii) with respect to any modification that occurs more than three months after the Closing Date and is not the result of a default or a reasonably foreseeable default under the Mortgage Loan, there is delivered to the Trustee an Opinion of Counsel (at the expense of the party seeking to modify the Mortgage Loan) to the effect that such modification would not be treated as giving rise to a new debt instrument for federal income tax purposes as described in the preceding sentence; provided, however, that no such Opinion of Counsel need be delivered if the sole purpose of the modification is to reduce the Monthly Payment on a Mortgage Loan as a result of a Curtailment such that the Mortgage Loan is fully amortized by its original maturity date. During the term of this Agreement, the Master Servicer shall consult fully with each Servicer as may be necessary from time to time to perform and carry out the Master Servicer's obligations hereunder and otherwise exercise reasonable efforts to encourage such Servicer to perform and observe the covenants, obligations and conditions to be performed or observed by it under its Servicing Agreement. The relationship of the Master Servicer to the Trustee under this Agreement is intended by the parties to be that of an independent contractor and not that of a joint venturer, partner or agent. The Master Servicer shall administer the Trust Estate on behalf of the Trustee and shall have full power and authority, acting alone or (subject to Section 6.06) through one or more subcontractors, to do any and all things in connection with such administration which it may deem necessary or desirable. Upon the execution and delivery of this Agreement, and from time to time as may be required thereafter, the Trustee shall furnish the Master Servicer or its subcontractors with any powers of attorney and such other documents as may be necessary or appropriate to enable the Master Servicer to carry out its administrative duties hereunder. The Seller shall have a limited option to repurchase any defaulted Mortgage Loan or REO Mortgage Loan during the following time periods: (i) beginning on the first day of the second month following the month in which the Master Servicer has reported that a Servicer has initiated foreclosure proceedings with respect to such a defaulted Mortgage Loan, with such repurchase option expiring on the last day of such second following month; (ii) beginning on the first day of the second month following the month in which the Master Servicer has reported that such defaulted Mortgage Loan has become an REO Mortgage Loan, with such repurchase option expiring on the last day of such second following month; and (iii) beginning on the day on which a Servicer accepts a contractual commitment by a third party to purchase the Mortgaged Property related to the defaulted Mortgage Loan or REO Mortgage Loan, with such repurchase option expiring on the earlier of the last day of the month in which such contractual commitment was accepted by the Servicer or the day immediately prior to the day on which the closing occurs with respect to such third party purchase of the Mortgaged Property related to the defaulted Mortgage Loan or REO Mortgage Loan. The Seller shall be entitled to repurchase at its option any Mortgage Loan in the Trust Estate which, pursuant to paragraph 5(b) of the Mortgage Loan Purchase Agreement, WFHM requests the Seller to repurchase and to sell to WFHM to facilitate the exercise of WFHM's rights against the originator or a prior holder of such Mortgage Loan. The purchase price for any Mortgage Loan repurchased pursuant to this paragraph shall be 100% of the unpaid principal balance of such Mortgage Loan plus accrued interest thereon at the Mortgage Interest Rate for such Mortgage Loan, through the last day of the month in which such repurchase occurs. Upon the receipt of such purchase price, the Master Servicer shall provide to the Trustee the certification required by Section 3.04 and the Trustee and the Custodian, if any, shall promptly release to the Seller the Owner Mortgage Loan File relating to the Mortgage Loan being repurchased. In the event that (i) the Master Servicer determines at any time that, notwithstanding the representations and warranties set forth in Section 2.03(b), any Mortgage Loan is not a "qualified mortgage" within the meaning of Section 860G of the Code and (ii) the Master Servicer is unable to enforce the obligation of the Seller to purchase such Mortgage Loan pursuant to Section 2.02 within two months of such determination, the Master Servicer shall cause such Mortgage Loan to be auctioned to the highest bidder and sold out of the Trust Estate no later than the date 90 days after such determination. In the event of any such sale of a Mortgage Loan, the Trustee shall, at the written request of the Master Servicer and upon being supported with appropriate forms therefor, within five Business Days of the deposit by the Master Servicer of the proceeds of such auction into the Certificate Account, release or cause to be released to the entity identified by the Master Servicer the related Owner Mortgage Loan File and Servicer Mortgage Loan File and shall execute and deliver such instruments of transfer or assignment, in each case without recourse, as shall be necessary to vest in the auction purchaser title to the Mortgage Loan and the Trustee shall have no further responsibility with regard to such Owner Mortgage Loan File or Servicer Mortgage Loan File. Neither the Trustee, the Master Servicer nor any Servicer, acting on behalf of the Trustee, shall provide financing from the Trust Estate to any purchaser of a Mortgage Loan. The Master Servicer, on behalf of the Trustee, shall, pursuant to the Servicing Agreements, object to the foreclosure upon, or other related conversion of the ownership of, any Mortgaged Property by the related Servicer if (i) the Master Servicer believes such Mortgaged Property may be contaminated with or affected by hazardous wastes or hazardous substances or (ii) such Servicer does not agree to administer such Mortgaged Property, once the related Mortgage Loan becomes an REO Mortgage Loan, in a manner which would not result in a federal tax being imposed upon the Trust Estate or the REMIC. The Master Servicer may enter into a special servicing agreement with an unaffiliated holder of 100% Percentage Interest of a Class of Class B Certificates or a holder of a class of securities representing interests in the Class B Certificates and/or other subordinated mortgage pass-through certificates, such agreement to be substantially in the form of Exhibit M hereto or subject to each Rating Agency's acknowledgement that the ratings of the Certificates in effect immediately prior to the entering into of such agreement would not be qualified, downgraded or withdrawn and the Certificates would not be placed on credit review status (except for possible upgrading) as a result of such agreement. Any such agreement may contain provisions whereby such holder may instruct the Master Servicer to instruct a Servicer to the extent provided in the applicable Servicing Agreement to commence or delay foreclosure proceedings with respect to delinquent Mortgage Loans and will contain provisions for the deposit of cash by the holder that would be available for distribution to Certificateholders if Liquidation Proceeds are less than they otherwise may have been had the Servicer acted in accordance with its normal procedures. SECTION 3.09 TERMINATION AND SUBSTITUTION OF SERVICING AGREEMENTS. Upon the occurrence of any event for which a Servicer may be terminated pursuant to its Servicing Agreement, the Master Servicer shall promptly deliver to the Seller and the Trustee an Officer's Certificate certifying that an event has occurred which may justify termination of such Servicing Agreement, describing the circumstances surrounding such event and recommending what action should be taken by the Trustee with respect to such Servicer. If the Master Servicer recommends that such Servicing Agreement be terminated, the Master Servicer's certification must state that the breach is material and not merely technical in nature. Upon written direction of the Master Servicer, based upon such certification, the Trustee shall promptly terminate such Servicing Agreement. Notwithstanding the foregoing, in the event that (i) WFHM fails to make any advance, as a consequence of which the Trustee is obligated to make an advance pursuant to Section 3.03 and (ii) the Trustee provides WFHM written notice of the failure to make such advance and such failure shall continue unremedied for a period of 15 days after receipt of such notice, the Trustee shall terminate the WFHM Servicing Agreement without the recommendation of the Master Servicer. The Master Servicer shall indemnify the Trustee and hold it harmless from and against any and all claims, liabilities, costs and expenses (including, without limitation, reasonable attorneys' fees) arising out of, or assessed against the Trustee in connection with termination of such Servicing Agreement at the direction of the Master Servicer. If the Trustee terminates such Servicing Agreement, the Trustee may enter into a substitute Servicing Agreement with the Master Servicer or, at the Master Servicer's nomination, with another mortgage loan service company acceptable to the Trustee, the Master Servicer and each Rating Agency under which the Master Servicer or such substitute servicer, as the case may be, shall assume, satisfy, perform and carry out all liabilities, duties, responsibilities and obligations that are to be, or otherwise were to have been, satisfied, performed and carried out by such Servicer under such terminated Servicing Agreement. Until such time as the Trustee enters into a substitute servicing agreement with respect to the Mortgage Loans previously serviced by such Servicer, the Master Servicer shall assume, satisfy, perform and carry out all obligations which otherwise were to have been satisfied, performed and carried out by such Servicer under its terminated Servicing Agreement. However, in no event shall the Master Servicer be deemed to have assumed the obligations of a Servicer to advance payments of principal and interest on a delinquent Mortgage Loan in excess of the Master Servicer's independent Periodic Advance obligation under Section 3.03 of this Agreement. As compensation for the Master Servicer of any servicing obligations fulfilled or assumed by the Master Servicer, the Master Servicer shall be entitled to any servicing compensation to which a Servicer would have been entitled if the Servicing Agreement with such Servicer had not been terminated. SECTION 3.10 APPLICATION OF NET LIQUIDATION PROCEEDS. For all purposes under this agreement, Net Liquidation Proceeds received from a Servicer shall be allocated first to accrued and unpaid interest on the related Mortgage Loan and then to the unpaid principal balance thereof. SECTION 3.11 ACT REPORTS. The Master Servicer shall, on behalf of the Seller, make all filings required to be made by the Seller with respect to the Class A Certificates and the Class B-1, Class B-2 and Class B-3 Certificates pursuant to the Securities Exchange Act of 1934, as amended.

Notwithstanding the foregoing, after the Principal Balance of any Class (other than the Class A-R Certificate) has been reduced to zero, such Class will be entitled to no further distributions of principal or interest (including, without limitation, any Unpaid Interest Shortfalls). With respect to any Distribution Date, the amount of the Principal Adjustment, if any, attributable to any Class B Certificates will be allocated to the Classes of Class A Certificates (other than the Class A-PO Certificates) and any Class of Class B Certificates with a lower numerical designation pro rata based on their outstanding Principal Balances.

(d) (i) For purposes of determining whether the Classes of Class B Certificates are eligible to receive distributions of principal with respect to any Distribution Date, the following tests shall apply: (A) if the Current Class B-1 Fractional Interest is less than the Original Class B-1 Fractional Interest and the Class B-1 Principal Balance is greater than zero, the Class B-2, Class B-3, Class B-4, Class B-5 and Class B-6 Certificates shall not be eligible to receive distributions of principal; or (B) if the Current Class B-2 Fractional Interest is less than the Original Class B-2 Fractional Interest and the Class B-2 Principal Balance is greater than zero, the Class B-3, Class B-4, Class B-5 and Class B-6 Certificates shall not be eligible to receive distributions of principal; or (C) if the Current Class B-3 Fractional Interest is less than the Original Class B-3 Fractional Interest and the Class B-3 Principal Balance is greater than zero, the Class B-4, Class B-5 and Class B-6 Certificates shall not be eligible to receive distributions of principal; or (D) if the Current Class B-4 Fractional Interest is less than the Original Class B-4 Fractional Interest and the Class B-4 Principal Balance is greater than zero, the Class B-5 and Class B-6 Certificates shall not be eligible to receive distributions of principal; or (E) if the Current Class B-5 Fractional Interest is less than the Original Class B-5 Fractional Interest and the Class B-5 Principal Balance is greater than zero, the Class B-6 Certificates shall not be eligible to receive distributions of principal. (ii) Notwithstanding the foregoing, if on any Distribution Date the aggregate distributions to Holders of the Classes of Class B Certificates entitled to receive distributions of principal would reduce the Principal Balances of the Classes of Class B Certificates entitled to receive distributions of principal below zero, first the Class B Prepayment Percentage of any affected Class of Class B Certificates for such Distribution Date beginning with the affected Class with the lowest numerical Class designation and then, if necessary, the Class B Percentage of such Class of the Class B Certificates for such Distribution Date shall be reduced to the respective percentages necessary to bring the Principal Balance of such Class of Class B Certificates to zero. The Class B Prepayment Percentages and the Class B Percentages of the remaining Classes of Class B Certificates will be recomputed substituting for the Subordinated Prepayment Percentage and Subordinated Percentage in such computations the difference between (A) the Subordinated Prepayment Percentage or Subordinated Percentage, as the case may be, and (B) the percentages determined in accordance with the preceding sentence necessary to bring the Principal Balances of the affected Classes of Class B Certificates to zero; provided, however, that if the Principal Balances of all the Classes of Class B Certificates eligible to receive distributions of principal shall be reduced to zero on such Distribution Date, the Class B Prepayment Percentage and the Class B Percentage of the Class of Class B Certificates with the lowest numerical Class designation which would otherwise be ineligible to receive distributions of principal in accordance with this Section shall equal the remainder of the Subordinated Prepayment Percentage for such Distribution Date minus the sum of the Class B Prepayment Percentages of the Classes of Class B Certificates having lower numerical Class designations, if any, and the remainder of the Subordinated Percentage for such Distribution Date minus the sum of the Class B Percentages of the Classes of Class B Certificates having lower numerical Class designations, if any, respectively. Any entitlement of any Class of Class B Certificates to principal payments solely pursuant to this clause (ii) shall not cause such Class to be regarded as being eligible to receive principal distributions for the purpose of applying the definition of its Class B Percentage or Class B Prepayment Percentage. (e) On each Distribution Date other than the Final Distribution Date (if such Final Distribution Date is in connection with a purchase of the assets of the Trust Estate by the Seller), the Paying Agent shall, on behalf of the Master Servicer, from funds remitted to it by the Master Servicer, distribute to each Certificateholder of record on the preceding Record Date (other than as provided in Section 9.01 respecting the final distribution to Certificateholders or in the last paragraph of this Section 4.01(e) respecting the final distribution in respect of any Class) either in immediately available funds by wire transfer to the account of such Certificateholder at a bank or other entity having appropriate facilities therefor, if such Certificateholder holds Certificates having a Denomination at least equal to that specified in Section 11.23, and has so notified the Master Servicer or, if applicable, the Paying Agent at least seven Business Days prior to the Distribution Date or, if such Holder holds Certificates having, in the aggregate, a Denomination less than the requisite minimum Denomination or if such Holder holds the Class A-R Certificate or has not so notified the Paying Agent, by check mailed to such Holder at the address of such Holder appearing in the Certificate Register, such Holder's share of the Class A Distribution Amount with respect to each Class of Class A Certificates and the Class B Distribution Amount with respect to each Class of Class B Certificates. In the event that, on any Distribution Date prior to the Final Distribution Date, the Principal Balance of any Class of Class A Certificates (other than the Class A-R Certificate) or the Principal Balance of any Class of Class B Certificates would be reduced to zero, the Master Servicer shall, as soon as practicable after the Determination Date relating to such Distribution Date, send a notice to the Trustee. The Trustee will then send a notice to each Certificateholder of such Class with a copy to the Certificate Registrar, specifying that the final distribution with respect to such Class will be made on such Distribution Date only upon the presentation and surrender of such Certificateholder's Certificates at the office or agency of the Trustee therein specified; provided, however, that the failure to give such notice will not entitle a Certificateholder to any interest beyond the interest payable with respect to such Distribution Date in accordance with Section 4.01(a). (f) The Paying Agent (or if no Paying Agent is appointed by the Master Servicer, the Master Servicer) shall withhold or cause to be withheld such amounts as may be required by the Code (giving full effect to any exemptions from withholding and related certifications required to be furnished by Certificateholders and any reductions to withholding by virtue of any bilateral tax treaties and any applicable certification required to be furnished by Certificateholders with respect thereto) from distributions to be made to Persons other than U.S. Persons ("Non-U.S. Persons"). Amounts withheld pursuant to this Section 4.01(f) shall be treated as having been distributed to the related Certificateholder for all purposes of this Agreement. For the purposes of this paragraph, a "U.S. Person" is a citizen or resident of the United States, a corporation or partnership (unless, in the case of a partnership, Treasury regulations are adopted that provide otherwise) created or organized in or under the laws of the United States, any state thereof or the District of Columbia, including an entity treated as a corporation or partnership for federal income tax purposes, an estate whose income is subject to United States federal income tax regardless of its source, or a trust if a court within the United States is able to exercise primary supervision over the administration of such trust, and one or more such U.S. Persons have the authority to control all substantial decisions of such trust (or, to the extent provided in applicable Treasury regulations, certain trusts in existence on August 20, 1996 which are eligible to elect to be treated as U.S. Persons). SECTION 4.02 ALLOCATION OF REALIZED LOSSES. (a) With respect to any Distribution Date, the principal portion of Realized Losses (other than Debt Service Reductions, Excess Special Hazard Losses, Excess Fraud Losses and Excess Bankruptcy Losses) will be allocated as follows: first, to the Class B-6 Certificates until the Class B-6 Principal Balance has been reduced to zero; second, to the Class B-5 Certificates until the Class B-5 Principal Balance has been reduced to zero; third, to the Class B-4 Certificates until the Class B-4 Principal Balance has been reduced to zero; fourth, to the Class B-3 Certificates until the Class B-3 Principal Balance has been reduced to zero; fifth, to the Class B-2 Certificates until the Class B-2 Principal Balance has been reduced to zero; sixth, to the Class B-1 Certificates until the Class B-1 Principal Balance has been reduced to zero; and seventh, concurrently, to the Class A Certificates (other than the Class A-PO Certificates) and Class A-PO Certificates, pro rata, based on the Non-PO Fraction and the PO Fraction, respectively. This allocation of Realized Losses will be effected through the reduction of the applicable Class's Principal Balance. (b) With respect to any Distribution Date, the principal portion of Excess Special Hazard Losses, Excess Fraud Losses and Excess Bankruptcy Losses occurring with respect to any Mortgage Loan allocable to the Class A-PO Certificates will equal the product of the amount of any such principal loss and the PO Fraction for such Mortgage Loan. The principal portion of any Excess Special Hazard Losses, Excess Fraud Losses and Excess Bankruptcy Losses remaining after allocation to the Class A-PO Certificates in accordance with the preceding sentence shall be allocated pro rata among the Class A Certificates (other than the Class A-PO Certificates) and Class B Certificates based on the Class A Non-PO Principal Balance and the Class B Principal Balance, respectively. Any such loss allocated to the Class A Certificates shall be allocated on the subsequent Determination Date to the outstanding Classes of Class A Certificates (other than the Class A-PO Certificates) in accordance with the Class A Loss Percentages as of such Determination Date. Any such loss allocated to the Class B Certificates shall be allocated pro rata among the outstanding Classes of Class B Certificates based on their Principal Balances. (c) Any Realized Losses allocated to a Class of Class A Certificates or Class B Certificates pursuant to Section 4.02(a) or Section 4.02(b) shall be allocated among the Certificates of such Class based on their Percentage Interests. (d) [Intentionally Left Blank] (e) The interest portion of Excess Special Hazard Losses, Excess Fraud Losses and Excess Bankruptcy Losses shall be allocated between (i) the Class A Certificates and (ii) the Class B Certificates, pro rata based on the Class A Interest Accrual Amount and the Class B Interest Accrual Amount for the related Distribution Date, without regard to any reduction pursuant to this sentence. Any such loss allocated to the Class A Certificates shall be allocated among the outstanding Classes of Class A Certificates based on each Class's Class A Interest Percentage. Any such loss allocated to the Class B Certificates will be allocated among the outstanding Classes of Class B Certificates based on their Class B Interest Percentages. In addition, after the Class B Principal Balance has been reduced to zero, the interest portion of Realized Losses (other than Excess Special Hazard Losses, Excess Fraud Losses and Excess Bankruptcy Losses) will be allocated among the outstanding Classes of Class A Certificates based on their Class A Interest Percentages. (f) Realized Losses allocated in accordance with this Section 4.02 will be allocated as follows: (i) Liquidated Loan Losses on Liquidated Loans for which the Liquidation Proceeds were received during, and Bankruptcy Losses incurred in a period corresponding to, an Unscheduled Principal Receipt Period for Full Unscheduled Principal Receipts that is a Mid-Month Receipt Period will be allocated on the Determination Date in the month following the month in which such Mid-Month Receipt Period ended and (ii) Liquidated Loan Losses on Liquidated Loans for which the Liquidation Proceeds were received during, and Bankruptcy Losses incurred in a period corresponding to, an Unscheduled Principal Receipt Period for Full Unscheduled Principal Receipts that is a Prior Month Receipt Period will be allocated on the Determination Date in the second month following the month which is such Prior Month Receipt Period. SECTION 4.03 PAYING AGENT. (a) The Master Servicer hereby appoints the Trustee as initial Paying Agent to make distributions to Certificateholders and to forward to Certificateholders the periodic statements and the annual statements required by Section 4.04 as agent of the Master Servicer. The Master Servicer may, at any time, remove or replace the Paying Agent. The Master Servicer shall cause any Paying Agent that is not the Trustee to execute and deliver to the Trustee an instrument in which such Paying Agent agrees with the Trustee that such Paying Agent shall: (i) hold all amounts remitted to it by the Master Servicer for distribution to Certificateholders in trust for the benefit of Certificateholders until such amounts are distributed to Certificateholders or otherwise disposed of as herein provided; (ii) give the Trustee notice of any default by the Master Servicer in remitting any required amount; and (iii) at any time during the continuance of any such default, upon the written request of the Trustee, forthwith pay to the Trustee all amounts held in trust by such Paying Agent. (b) The Paying Agent shall establish and maintain a Payment Account, which shall be a separate trust account and an Eligible Account, in which the Master Servicer shall cause to be deposited from funds in the Certificate Account or, to the extent required hereunder, from its own funds (i) at or before 10:00 a.m., New York time, on the Business Day preceding each Distribution Date, by wire transfer of immediately available funds, any Periodic Advance for such Distribution Date, pursuant to Section 3.03 and (ii) at or before 10:00 a.m., New York time, on the Business Day preceding each Distribution Date, by wire transfer of immediately available funds, an amount equal to the Pool Distribution Amount. The Master Servicer may cause the Paying Agent to invest the funds in the Payment Account. Any such investment shall be in Eligible Investments, which shall mature not later than the Business Day preceding the related Distribution Date (unless the Eligible Investments are obligations of the Trustee, in which case such Eligible Investments shall mature not later than the Distribution Date), and shall not be sold or disposed of prior to maturity. All income and gain realized from any such investment shall be for the benefit of the Master Servicer and shall be subject to its withdrawal or order from time to time. The amount of any losses incurred in respect of any such investments shall be deposited in the Payment Account by the Master Servicer out of its own funds immediately as realized. The Paying Agent may withdraw from the Payment Account any amount deposited in the Payment Account that was not required to be deposited therein and may clear and terminate the Payment Account pursuant to Section 9.01.

and shall deliver a copy of each type of statement to the Trustee, who shall provide copies thereof to Persons making written request therefor at the Corporate Trust Office. In the case of information furnished with respect to a Class of Class A Certificates pursuant to clauses (i) and (ii) above and with respect to a Class of Class B Certificates pursuant to clauses (iii) and (iv) above, the amounts shall be expressed as a dollar amount per Class A or Class B Certificate (other than the Class A-R Certificate) with a $1,000 Denomination, and as a dollar amount per Class A-R Certificate with a $100 Denomination. Within a reasonable period of time after the end of each calendar year, the Master Servicer shall furnish or cause to be furnished to each Person who at any time during the calendar year was the Holder of a Certificate a statement containing the information set forth in clauses (i) and (ii)(a) above in the case of a Class A Certificateholder and the information set forth in clauses (iii) and (iv)(a) above in the case of a Class B Certificateholder aggregated for such calendar year or applicable portion thereof during which such Person was a Certificateholder. Such obligation of the Master Servicer shall be deemed to have been satisfied to the extent that substantially comparable information shall be provided by the Master Servicer pursuant to any requirements of the Code from time to time in force. Prior to the close of business on the third Business Day preceding each Distribution Date, the Master Servicer shall furnish a statement to the Trustee, any Paying Agent and the Seller (the information in such statement to be made available to Certificateholders by the Master Servicer on written request) setting forth the Class A Distribution Amount with respect to each Class of Class A Certificates and the Class B Distribution Amount with respect to each Class of Class B Certificates. The determination by the Master Servicer of such amounts shall, in the absence of obvious error, be presumptively deemed to be correct for all purposes hereunder and the Trustee and the Paying Agent shall be protected in relying upon the same without any independent check or verification. In addition to the reports required pursuant to this Section 4.04, the Master Servicer shall make available upon request to each Holder and each proposed transferee of a Class B-4, Class B-5 or Class B-6 Certificate such additional information, if any, as may be required to permit the proposed transfer to be effected pursuant to Rule 144A. SECTION 4.05 REPORTS TO MORTGAGORS AND THE INTERNAL REVENUE SERVICE. The Master Servicer shall, in each year beginning after the Cut-Off Date, make the reports of foreclosures and abandonments of any Mortgaged Property as required by Code Section 6050J. In order to facilitate this reporting process, the Master Servicer shall request that each Servicer, on or before January 15th of each year, shall provide to the Internal Revenue Service, with copies to the Master Servicer, reports relating to each instance occurring during the previous calendar year in which such Servicer (i) on behalf of the Trustee acquires an interest in a Mortgaged Property through foreclosure or other comparable conversion in full or partial satisfaction of a Mortgage Loan serviced by such Servicer, or (ii) knows or has reason to know that a Mortgaged Property has been abandoned. Reports from the Servicers shall be in form and substance sufficient to meet the reporting requirements imposed by Code Section 6050J. In addition, each Servicer shall provide the Master Servicer with sufficient information to allow the Master Servicer to, for each year ending after the Cut-Off Date, provide, or cause to be provided, to the Internal Revenue Service and the Mortgagors such information as is required under Code Sections 6050H (regarding payment of interest) and 6050P (regarding cancellation of indebtedness). SECTION 4.06 CALCULATION OF AMOUNTS; BINDING EFFECT OF INTERPRETATIONS AND ACTIONS OF MASTER SERVICER. The Master Servicer will compute the amount of all distributions to be made on the Certificates and all losses to be allocated to the Certificates. In the event that the Master Servicer concludes that any ambiguity or uncertainty exists in any provisions of this Agreement relating to distributions to be made on the Certificates, the allocation of losses to the Certificates or otherwise, the interpretation of such provisions and any actions taken by the Master Servicer in good faith to implement such interpretation shall be binding upon Certificateholders. ARTICLE V THE CERTIFICATES SECTION 5.01 THE CERTIFICATES. (a) The Class A and Class B Certificates shall be issued only in minimum Denominations of a Single Certificate and, except for the Class A-R Certificate, integral multiples of $1,000 in excess thereof (except, if necessary, for one Certificate of each Class (other than the Class A-R Certificate) that evidences one Single Certificate plus such additional principal portion as is required in order for all Certificates of such Class to equal the aggregate Original Principal Balance of such Class), and shall be substantially in the respective forms set forth as Exhibits A-1, A-2, A-3, A-4, A-5, A-6, A-PO, A-R, B-1, B-2, B-3, B-4, B-5, B-6 and C (reverse side of Certificates) hereto. On original issue the Certificates shall be executed and delivered by the Trustee to or upon the order of the Seller upon receipt by the Trustee or the Custodian of the documents specified in Section 2.01. The aggregate principal portion evidenced by the Class A and Class B Certificates shall be the sum of the amounts specifically set forth in the respective Certificates. The Certificates shall be executed by manual or facsimile signature on behalf of the Trustee by any Responsible Officer thereof. Certificates bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Trustee shall bind the Trustee notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Certificates or did not hold such offices at the date of such Certificates. No Certificate shall be entitled to any benefit under this Agreement, or be valid for any purpose, unless manually countersigned by a Responsible Officer of the Trustee, or unless there appears on such Certificate a certificate of authentication executed by the Authenticating Agent by manual signature, and such countersignature or certificate upon a 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. Until such time as Definitive Certificates are issued pursuant to Section 5.07, each Book-Entry Certificate shall bear the following legend: "Unless this certificate is presented by an authorized representative of [the Clearing Agency] to the Seller or its agent for registration of transfer, exchange or payment, and any certificate issued is registered in the name of [the Clearing Agency] or such other name as requested by an authorized representative of [the Clearing Agency] and any payment is made to [the Clearing Agency], any transfer, pledge or other use hereof for value or otherwise by or to any person is wrongful since the registered owner hereof, [the Clearing Agency], has an interest herein." (b) Upon original issuance, the Book-Entry Certificates shall be issued in the form of one or more typewritten certificates, to be delivered to The Depository Trust Company, the initial Clearing Agency, by, or on behalf of, the Seller or to, and deposited with the Certificate Custodian, on behalf of The Depository Trust Company, if directed to do so pursuant instructions from The Depository Trust Company. Such Certificates shall initially be registered in the Certificate Register in the name of the nominee of the initial Clearing Agency, and no Beneficial Owner will receive a definitive certificate representing such Beneficial Owner's interest in the Book-Entry Certificates, except as provided in Section 5.07. Unless and until definitive, fully registered certificates ("Definitive Certificates") have been issued to Beneficial Owners pursuant to Section 5.07: (i) the provisions of this Section 5.01(b) shall be in full force and effect; (ii) the Seller, the Master Servicer, the Certificate Registrar and the Trustee may deal with the Clearing Agency for all purposes (including the making of distributions on the Book-Entry Certificates and the taking of actions by the Holders of Book-Entry Certificates) as the authorized representative of the Beneficial Owners; (iii) to the extent that the provisions of this Section 5.01(b) conflict with any other provisions of this Agreement, the provisions of this Section 5.01(b) shall control; (iv) the rights of Beneficial Owners shall be exercised only through the Clearing Agency and shall be limited to those established by law, the rules, regulations and procedures of the Clearing Agency and agreements between such Beneficial Owners and the Clearing Agency and/or the Clearing Agency Participants, and all references in this Agreement to actions by Certificateholders shall, with respect to the Book-Entry Certificates, refer to actions taken by the Clearing Agency upon instructions from the Clearing Agency Participants, and all references in this Agreement to distributions, notices, reports and statements to Certificateholders shall, with respect to the Book-Entry Certificates, refer to distributions, notices, reports and statements to the Clearing Agency or its nominee, as registered holder of the Book-Entry Certificates, as the case may be, for distribution to Beneficial Owners in accordance with the procedures of the Clearing Agency; and (v) the initial Clearing Agency will make book-entry transfers among the Clearing Agency Participants and receive and transmit distributions of principal and interest on the Certificates to the Clearing Agency Participants, for distribution by such Clearing Agency Participants to the Beneficial Owners or their nominees. For purposes of any provision of this Agreement requiring or permitting actions with the consent of, or at the direction of, Holders of Book-Entry Certificates evidencing specified Voting Interests, such direction or consent shall be given by Beneficial Owners having the requisite Voting Interests, acting through the Clearing Agency. Unless and until Definitive Certificates have been issued to Beneficial Owners pursuant to Section 5.07, copies of the reports or statements referred to in Section 4.04 shall be available to Beneficial Owners upon written request to the Trustee at the Corporate Trust Office. SECTION 5.02 REGISTRATION OF CERTIFICATES. (a) The Trustee shall cause to be kept at one of the offices or agencies to be maintained in accordance with the provisions of Section 5.06 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. The Trustee shall act as, or shall appoint, a Certificate Registrar for the purpose of registering Certificates and transfers and exchanges of Certificates as herein provided. Upon surrender for registration of transfer of any Certificate at any office or agency maintained for such purpose pursuant to Section 5.06 (and subject to the provisions of this Section 5.02) the Trustee shall execute, and shall date, authenticate (or cause the Authenticating Agent to authenticate) and deliver, in the name of the designated transferee or transferees, one or more new Certificates of a like aggregate principal portion or Percentage Interest and of the same Class. At the option of the Certificateholders, Certificates may be exchanged for other Certificates of authorized Denominations of a like aggregate principal portion or Percentage Interest and of the same Class upon surrender of the Certificates to be exchanged at any such office or agency. Whenever any Certificates are so surrendered for exchange, the Trustee shall execute, and shall date, authenticate (or cause the Authenticating Agent to authenticate) and deliver, the Certificates which the Certificateholder making the exchange is entitled to receive. Every Certificate presented or surrendered for transfer or exchange shall (if so required by the Certificate Registrar or the Trustee) be duly endorsed by, or be accompanied by a written instrument of transfer in form satisfactory to the Certificate Registrar, duly executed by the Holder thereof or his attorney duly authorized in writing. No service charge shall be made for any transfer or exchange of Certificates, but the Trustee or the Certificate Registrar may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any transfer or exchange of Certificates. All Certificates surrendered for transfer and exchange shall be canceled by the Certificate Registrar, the Trustee or the Authenticating Agent in accordance with their standard procedures. (b) No transfer of a Class B-4, Class B-5 or Class B-6 Certificate shall be made unless the registration requirements of the Securities Act of 1933, as amended, and any applicable State securities laws are complied with, or such transfer is exempt from the registration requirements under said Act and laws. In the event that a transfer is to be made in reliance upon an exemption from said Act or laws, (i) unless such transfer is made in reliance on Rule 144A, the Trustee or the Seller may, if such transfer is to be made within three years after the later of (i) the date of the initial sale of Certificates or (ii) the last date on which the Seller or any affiliate thereof was a Holder of the Certificates proposed to be transferred, require a Class B-4, Class B-5 or Class B-6 Certificateholder to deliver a written Opinion of Counsel acceptable to and in form and substance satisfactory to the Trustee and the Seller, to the effect that such transfer may be made pursuant to an exemption, describing the applicable exemption and the basis therefor, from said Act and laws or is being made pursuant to said Act and laws, which Opinion of Counsel shall not be an expense of the Trustee, the Seller or the Master Servicer, and (ii) the Trustee shall require the transferee (other than an affiliate of the Seller on the Closing Date) to execute an investment letter in the form of Exhibit J hereto certifying to the Seller and the Trustee the facts surrounding such transfer, which investment letter shall not be an expense of the Trustee, the Seller or the Master Servicer. The Holder of a Class B-4, Class B-5 or Class B-6 Certificate desiring to effect such transfer shall, and does hereby agree to, indemnify the Trustee, the Seller, the Master Servicer and any Paying Agent acting on behalf of the Trustee 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. Neither the Seller nor the Trustee is under an obligation to register the Class B-4, Class B-5 or Class B-6 Certificates under said Act or any other securities law. (c) No transfer of a Class B-4, Class B-5 or Class B-6 Certificate shall be made unless the Trustee and the Seller shall have received (i) a representation letter from the transferee in the form of Exhibit J hereto, to the effect that either (a) such transferee is not an employee benefit plan or other retirement arrangement subject to Title I of ERISA or Code Section 4975, or a governmental plan, as defined in Section 3(32) of ERISA, subject to any federal, state or local law ("Similar Law") which is to a material extent similar to the foregoing provisions of ERISA or the Code (collectively, a "Plan") and is not a person acting on behalf of or using the assets of any such Plan, which representation letter shall not be an expense of the Trustee, the Seller or the Master Servicer or (b) if such transferee is an insurance company, (A) the source of funds used to purchase the Class B-4, Class B-5 or Class B-6 Certificate is an "insurance company general account" (as such term is defined in Section V(e) of Prohibited Transaction Class Exemption 95-60 ("PTE 95-60"), 60 Fed. Reg. 35925 (July 12, 1995)), (B) there is no Plan with respect to which the amount of such general account's reserves and liabilities for the contract(s) held by or on behalf of such Plan and all other Plans maintained by the same employer (or affiliate thereof as defined in Section V(a)(1) of PTE 95-60) or by the same employee organization exceeds 10% of the total of all reserves and liabilities of such general account (as such amounts are determined under Section I(a) of PTE 95-60) at the date of acquisition and (C) the purchase and holding of such Class B-4, Class B-5 or Class B-6 Certificate are covered by Sections I and III of PTE 95-60 or (ii) in the case of any such Class B-4, Class B-5 or Class B-6 Certificate presented for registration in the name of a Plan, or a trustee of any such Plan, (A) an Opinion of Counsel satisfactory to the Trustee and the Seller to the effect that the purchase or holding of such Class B-4, Class B-5 or Class B-6 Certificate will not result in the assets of the Trust Estate being deemed to be "plan assets" and subject to the prohibited transaction provisions of ERISA, the Code or Similar Law and will not subject the Trustee, the Seller or the Master Servicer to any obligation in addition to those undertaken in this Agreement, which Opinion of Counsel shall not be an expense of the Trustee, the Seller or the Master Servicer and (B) such other opinions of counsel, officer's certificates and agreements as the Seller or the Master Servicer may require in connection with such transfer, which opinions of counsel, officers' certificates and agreements shall not be an expense of the Trustee, the Seller or the Master Servicer. The Class B-4, Class B-5 and Class B-6 Certificates shall bear a legend referring to the foregoing restrictions contained in this paragraph. (d) No legal or beneficial interest in all or any portion of the Class A-R Certificate may be transferred directly or indirectly to a "disqualified organization" within the meaning of Code Section 860E(e)(5) or an agent of a disqualified organization (including a broker, nominee, or middleman), to a Plan or a Person acting on behalf of or investing the assets of a Plan (such Plan or Person, an "ERISA Prohibited Holder") or to an individual, corporation, partnership or other person unless such transferee (i) is not a Non-U.S. Person or (ii) is a Non-U.S. Person that holds the Class A-R Certificate in connection with the conduct of a trade or business within the United States and has furnished the transferor and the Trustee with an effective Internal Revenue Service Form 4224 or (iii) is a Non-U.S. Person that has delivered to both the transferor and the Trustee an opinion of a nationally recognized tax counsel to the effect that the transfer of the Class A-R Certificate to it is in accordance with the requirements of the Code and the regulations promulgated thereunder and that such transfer of the Class A-R Certificate will not be disregarded for federal income tax purposes (any such person who is not covered by clauses (i), (ii) or (iii) above being referred to herein as a "Non-permitted Foreign Holder"), and any such purported transfer shall be void and have no effect. The Trustee shall not execute, and shall not authenticate (or cause the Authenticating Agent to authenticate) and deliver, a new Class A-R Certificate in connection with any such transfer to a disqualified organization or agent thereof (including a broker, nominee or middleman), an ERISA Prohibited Holder or a Non-permitted Foreign Holder, and neither the Certificate Registrar nor the Trustee shall accept a surrender for transfer or registration of transfer, or register the transfer of, the Class A-R Certificate, unless the transferor shall have provided to the Trustee an affidavit, substantially in the form attached as Exhibit H hereto, signed by the transferee, to the effect that the transferee is not such a disqualified organization, an agent (including a broker, nominee, or middleman) for any entity as to which the transferee has not received a substantially similar affidavit, an ERISA Prohibited Holder or a Non-permitted Foreign Holder, which affidavit shall contain the consent of the transferee to any such amendments of this Agreement as may be required to further effectuate the foregoing restrictions on transfer of the Class A-R Certificate to disqualified organizations, ERISA Prohibited Holders or Non-permitted Foreign Holders. Such affidavit shall also contain the statement of the transferee that (i) the transferee has historically paid its debts as they have come due and intends to do so in the future, (ii) the transferee understands that it may incur liabilities in excess of cash flows generated by the residual interest, (iii) the transferee intends to pay taxes associated with holding the residual interest as they become due and (iv) the transferee will not transfer the Class A-R Certificate to any Person who does not provide an affidavit substantially in the form attached as Exhibit H hereto. The affidavit described in the preceding paragraph, if not executed in connection with the initial issuance of the Class A-R Certificate, shall be accompanied by a written statement in the form attached as Exhibit I hereto, signed by the transferor, to the effect that as of the time of the transfer, the transferor has no actual knowledge that the transferee is a disqualified organization, ERISA Prohibited Holder or Non-permitted Foreign Holder, and has no knowledge or reason to know that the statements made by the transferee with respect to clauses (i) and (iii) of the last sentence of the preceding paragraph are not true. The Class A-R Certificate shall bear a legend referring to the foregoing restrictions contained in this paragraph and the preceding paragraph. Upon notice to the Master Servicer that any legal or beneficial interest in any portion of the Class A-R Certificate has been transferred, directly or indirectly, to a disqualified organization or agent thereof (including a broker, nominee, or middleman) in contravention of the foregoing restrictions, (i) such transferee shall be deemed to hold the Class A-R Certificate in constructive trust for the last transferor who was not a disqualified organization or agent thereof, and such transferor shall be restored as the owner of such Class A-R Certificate as completely as if such transfer had never occurred, provided that the Master Servicer may, but is not required to, recover any distributions made to such transferee with respect to the Class A-R Certificate, and (ii) the Master Servicer agrees to furnish to the Internal Revenue Service and to any transferor of the Class A-R Certificate or such agent (within 60 days of the request therefor by the transferor or agent) such information necessary to the application of Code Section 860E(e) as may be required by the Code, including but not limited to the present value of the total anticipated excess inclusions with respect to the Class A-R Certificate (or portion thereof) for periods after such transfer. At the election of the Master Servicer, the cost to the Master Servicer of computing and furnishing such information may be charged to the transferor or such agent referred to above; however, the Master Servicer shall in no event be excused from furnishing such information. SECTION 5.03 MUTILATED, DESTROYED, LOST OR STOLEN CERTIFICATES. If (i) any mutilated Certificate is surrendered to the Trustee or the Authenticating Agent, or the Trustee or the Authenticating Agent receives evidence to its satisfaction of the destruction, loss or theft of any Certificate, and (ii) there is delivered to the Trustee or the Authenticating Agent such security or indemnity as may be required by them to hold each of them harmless, then, in the absence of notice to the Trustee or the Authenticating Agent that such Certificate has been acquired by a bona fide purchaser, the Trustee shall execute and authenticate (or cause the Authenticating Agent to 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 principal portion or Percentage Interest and of the same Class. Upon the issuance of any new Certificate under this Section, the Trustee or the Certificate Registrar 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 expense (including the fees and expenses of the Trustee or the Authenticating Agent) in connection therewith. Any duplicate Certificate issued pursuant to this Section shall constitute complete and indefeasible evidence of ownership in the Trust Estate, as if originally issued, whether or not the lost, stolen, or destroyed Certificate shall be found at any time. SECTION 5.04 PERSONS DEEMED OWNERS. Prior to the due presentation of a Certificate for registration of transfer, the Seller, the Master Servicer, the Trustee, the Certificate Registrar and any agent of the Seller, the Master Servicer, the Trustee or the Certificate Registrar may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions pursuant to Section 4.01, and for all other purposes whatsoever, and neither the Seller, the Master Servicer, the Trustee, the Certificate Registrar nor any agent of the Seller, the Master Servicer, the Trustee or the Certificate Registrar shall be affected by notice to the contrary. SECTION 5.05 ACCESS TO LIST OF CERTIFICATEHOLDERS' NAMES AND ADDRESSES. (a) If the Trustee is not acting as Certificate Registrar, the Certificate Registrar shall furnish or cause to be furnished to the Trustee, within 15 days after receipt by the Certificate Registrar of a request by the Trustee in writing, a list, in such form as the Trustee may reasonably require, of the names and addresses of the Certificateholders of each Class as of the most recent Record Date. (b) If five or more Certificateholders (hereinafter referred to as "applicants") apply in writing to the Trustee, and such application states that the applicants desire to communicate with other Certificateholders with respect to their rights under this Agreement or under the Certificates and is accompanied by a copy of the communication which such applicants propose to transmit, then the Trustee shall, within five Business Days following the receipt of such application, afford such applicants access during normal business hours to the most recent list of Certificateholders held by the Trustee. If such a list is as of the date more than 90 days prior to the date of receipt of such applicants' request and the Trustee is not the Certificate Registrar, the Trustee shall promptly request from the Certificate Registrar a current list as provided in paragraph (a) hereof, and shall afford such applicants access to such list promptly upon receipt. (c) Every Certificateholder, by receiving and holding a Certificate, agrees with the Seller, the Master Servicer, the Certificate Registrar and the Trustee that neither the Seller, the Master Servicer, the Certificate Registrar nor the Trustee shall be held accountable by reason of the disclosure of any such information as to the names, addresses and Percentage Interests of the Certificateholders hereunder, regardless of the source from which such information was delivered. SECTION 5.06 MAINTENANCE OF OFFICE OR AGENCY. The Trustee will maintain, at its expense, an office or agency where Certificates may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Certificate Registrar in respect of the Certificates and this Agreement may be served. The Trustee initially designates the Corporate Trust Office and the principal corporate trust office of the Authenticating Agent, if any, as its offices and agencies for said purposes. SECTION 5.07 DEFINITIVE CERTIFICATES. If (i)(A) the Master Servicer advises the Trustee in writing that the Clearing Agency is no longer willing or able properly to discharge its responsibilities as depository with respect to the Book-Entry Certificates, and (B) the Master Servicer is unable to locate a qualified successor, (ii) the Master Servicer, at its option, advises the Trustee in writing that it elects to terminate the book-entry system through the Clearing Agency or (iii) after the occurrence of dismissal or resignation of the Master Servicer, Beneficial Owners representing aggregate Voting Interests of not less than 51% of the aggregate Voting Interests of each outstanding Class of Book-Entry Certificates advise the Trustee through the Clearing Agency and Clearing Agency Participants in writing that the continuation of a book-entry system through the Clearing Agency is no longer in the best interests of the Beneficial Owners, the Trustee shall notify the Beneficial Owners, through the Clearing Agency, of the occurrence of any such event and of the availability of Definitive Certificates to Beneficial Owners requesting the same. Upon surrender to the Trustee by the Clearing Agency of the Certificates held of record by its nominee, accompanied by reregistration instructions and directions to execute and authenticate new Certificates from the Master Servicer, the Trustee shall execute and authenticate Definitive Certificates for delivery at its Corporate Trust Office. The Master Servicer shall arrange for, and will bear all costs of, the printing and issuance of such Definitive Certificates. Neither the Seller, the Master Servicer nor the Trustee shall be liable for any delay in delivery of such instructions by the Clearing Agency and may conclusively rely on, and shall be protected in relying on, such instructions. SECTION 5.08 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 Beneficial Owners pursuant to Section 5.07, the Trustee shall give all such notices and communications specified herein to be given to Holders of Book-Entry Certificates to the Clearing Agency. ARTICLE VI THE SELLER AND THE MASTER SERVICER SECTION 6.01 LIABILITY OF THE SELLER AND THE MASTER SERVICER. The Seller and the Master Servicer shall each be liable in accordance herewith only to the extent of the obligations specifically imposed by this Agreement and undertaken hereunder by the Seller and the Master Servicer. SECTION 6.02 MERGER OR CONSOLIDATION OF THE SELLER OR THE MASTER SERVICER. Subject to the following paragraph, the Seller and the Master Servicer each will keep in full effect its existence, rights and franchises as a corporation under the laws of the jurisdiction of its incorporation, and will obtain and preserve its qualification to do business as a foreign corporation in each jurisdiction in which such qualification is or shall be necessary to protect the validity and enforceability of this Agreement, the Certificates or any of the Mortgage Loans and to perform its respective duties under this Agreement. The Seller or the Master Servicer may be merged or consolidated with or into any Person, or transfer all or substantially all of its assets to any Person, in which case any Person resulting from any merger or consolidation to which the Seller or Master Servicer shall be a party, or any Person succeeding to the business of the Seller or Master Servicer, shall be the successor of the Seller or Master Servicer hereunder, without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding; provided, however, that, in the case of the Master Servicer, any such successor or resulting Person shall be qualified to service mortgage loans for Fannie Mae or Freddie Mac. SECTION 6.03 LIMITATION ON LIABILITY OF THE SELLER, THE MASTER SERVICER AND OTHERS. Neither the Seller nor the Master Servicer nor any subcontractor nor any of the partners, directors, officers, employees or agents of any of them shall be under any liability to the Trust Estate or the Certificateholders and all such Persons shall be held harmless 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 any such Person against any breach of warranties or representations made herein or against any liability which would otherwise be imposed by reason 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 Seller, the Master Servicer, any subcontractor, and any partner, director, officer, employee or agent of any of them shall be entitled to indemnification by the Trust Estate and will be held harmless against any loss, liability or expense incurred in connection with the performance of its duties and obligations and any legal action relating to this Agreement or the Certificates, including, without limitation, any legal action against the Trustee in its capacity as Trustee hereunder, other than any loss, liability or expense (including, without limitation, expenses payable by the Master Servicer under Section 8.06) incurred by reason of willful misfeasance, bad faith or gross negligence in the performance of his or its duties hereunder or by reason of reckless disregard of his or its obligations and duties hereunder. The Seller, the Master Servicer and any of the directors, officers, employees or agents of either may rely in good faith on any document of any kind which, prima facie, is properly executed and submitted by any Person respecting any matters arising hereunder. Neither the Seller nor the Master Servicer shall be under any obligation to appear in, prosecute or defend any legal action unless such action is related to its respective duties under this Agreement and which in its opinion does not involve it in any expense or liability; provided, however, that the Seller or the Master Servicer may in its discretion undertake any such action which it may deem necessary or desirable with respect to this Agreement and the rights and duties of the parties hereto and the interests of the Certificateholders hereunder if the Certificateholders offer to the Seller or the Master Servicer, as the case may be, reasonable security or indemnity against the costs, expenses and liabilities which may be incurred therein or thereby. In such event, the legal expenses and costs of such action and any liability resulting therefrom shall be expenses, costs and liabilities of the Trust Estate, and the Seller or the Master Servicer shall be entitled to be reimbursed therefor out of the Certificate Account, and such amounts shall, on the following Distribution Date or Distribution Dates, be allocated in reduction of distributions on the Class A Certificates and Class B Certificates in the same manner as Realized Losses are allocated pursuant to Section 4.02(a). SECTION 6.04 RESIGNATION OF THE MASTER SERVICER. The Master Servicer shall not resign from the obligations and duties hereby imposed on it except upon determination that its duties hereunder are no longer permissible under applicable law or are in material conflict by reason of applicable law with any other activities carried on by it. Any such determination permitting the resignation of the Master Servicer shall be evidenced by an Opinion of Counsel to such effect delivered to the Trustee. No such resignation shall become effective until the Trustee or a successor servicer shall have assumed the Master Servicer's responsibilities, duties, liabilities and obligations hereunder. SECTION 6.05 COMPENSATION TO THE MASTER SERVICER. The Master Servicer shall be entitled to receive a monthly fee equal to the Master Servicing Fee, as compensation for services rendered by the Master Servicer under this Agreement. The Master Servicer also will be entitled to any late reporting fees paid by a Servicer pursuant to its Servicing Agreement, any investment income on funds on deposit in the Certificate Account and any Liquidation Profits to which a Servicer is not entitled under its Servicing Agreement. SECTION 6.06 ASSIGNMENT OR DELEGATION OF DUTIES BY MASTER SERVICER. The Master Servicer shall not assign or transfer any of its rights, benefits or privileges under this Agreement to any other Person, or delegate to or subcontract with, or authorize or appoint any other Person to perform any of the duties, covenants or obligations to be performed by the Master Servicer without the prior written consent of the Trustee, and any agreement, instrument or act purporting to effect any such assignment, transfer, delegation or appointment shall be void. Notwithstanding the foregoing, the Master Servicer shall have the right without the prior written consent of the Trustee (i) to assign its rights and delegate its duties and obligations hereunder; provided, however, that (a) the purchaser or transferee accepting such assignment or delegation is qualified to service mortgage loans for Fannie Mae or Freddie Mac, is satisfactory to the Trustee, in the exercise of its reasonable judgment, and executes and delivers to the Trustee an agreement, in form and substance reasonably satisfactory to the Trustee, which contains an assumption by such purchaser or transferee of the due and punctual performance and observance of each covenant and condition to be performed or observed by the Master Servicer hereunder from and after the date of such agreement; and (b) each applicable Rating Agency's rating of any Certificates in effect immediately prior to such assignment, sale or transfer is not reasonably likely to be qualified, downgraded or withdrawn as a result of such assignment, sale or transfer and the Certificates are not reasonably likely to be placed on credit review status by any such Rating Agency; and (ii) to delegate to, subcontract with, authorize, or appoint an affiliate of the Master Servicer to perform and carry out any duties, covenants or obligations to be performed and carried out by the Master Servicer under this Agreement and hereby agrees so to delegate, subcontract, authorize or appoint to an affiliate of the Master Servicer any duties, covenants or obligations to be performed and carried out by the Master Servicer to the extent that such duties, covenants or obligations are to be performed in any state or states in which the Master Servicer is not authorized to do business as a foreign corporation but in which the affiliate is so authorized. In no case, however, shall any permitted assignment and delegation relieve the Master Servicer of any liability to the Trustee or the Seller under this Agreement, incurred by it prior to the time that the conditions contained in clause (i) above are met. SECTION 6.07 INDEMNIFICATION OF TRUSTEE AND SELLER BY MASTER SERVICER. The Master Servicer shall indemnify and hold harmless the Trustee and the Seller and any director, officer or agent thereof against any loss, liability or expense, including reasonable attorney's fees, arising out of, in connection with or incurred by reason of willful misfeasance, bad faith or negligence in the performance of duties of the Master Servicer under this Agreement or by reason of reckless disregard of its obligations and duties under this Agreement. Any payment pursuant to this Section made by the Master Servicer to the Trustee or the Seller shall be from such entity's own funds, without reimbursement therefor. The provisions of this Section 6.07 shall survive the termination of this Agreement. ARTICLE VII DEFAULT SECTION 7.01 EVENTS OF DEFAULT. In case one or more of the following Events of Default by the Master Servicer shall occur and be continuing, that is to say: (i) any failure by the Master Servicer (a) to remit any funds to the Paying Agent as required by Section 4.03 or (b) to distribute or cause to be distributed to Certificateholders any payment required to be made by the Master Servicer under the terms of this Agreement which, in either case, continues unremedied for a period of three business days after the date upon which written notice of such failure, requiring the same to be remedied, shall have been given to the Master Servicer by the Trustee or to the Master Servicer and the Trustee by the holders of Certificates evidencing in the aggregate not less than 25% of the aggregate Voting Interest represented by all Certificates; (ii) any failure on the part of the Master Servicer duly to observe or perform in any material respect any other of the covenants or agreements on the part of the Master Servicer in the Certificates or in this Agreement which continues unremedied for a period of 60 days after the date on which written notice of such failure, requiring the same to be remedied, shall have been given to the Master Servicer by the Trustee, or to the Master Servicer and the Trustee by the holders of Certificates evidencing in the aggregate not less than 25% of the aggregate Voting Interest represented by all Certificates; (iii) a decree or order of a court or agency or supervisory authority having jurisdiction in the premises for the appointment of a trustee, conservator, receiver or liquidator in any bankruptcy, insolvency, readjustment of debt, marshaling of assets and liabilities or similar proceedings, or for the winding-up or liquidation of its affairs, shall have been entered against the Master Servicer and such decree or order shall have remained in force undischarged and unstayed for a period of 60 days; (iv) the Master Servicer shall consent to the appointment of a trustee, conservator, receiver or liquidator or liquidating committee in any bankruptcy, insolvency, readjustment of debt, marshaling of assets and liabilities, voluntary liquidation or similar proceedings of or relating to the Master Servicer, or of or relating to all or substantially all of its property; (v) the Master Servicer shall admit in writing its inability to pay its debts generally as they become due, file a petition to take advantage of any applicable insolvency, bankruptcy or reorganization statute, make an assignment for the benefit of its creditors or voluntarily suspend payment of its obligations; (vi) the Master Servicer shall be dissolved, or shall dispose of all or substantially all of its assets; or consolidate with or merge into another entity or shall permit another entity to consolidate or merge into it, such that the resulting entity does not meet the criteria for a successor servicer, as specified in Section 6.02 hereof; or (vii) the Master Servicer and any subservicer appointed by it becomes ineligible to service for both Fannie Mae and Freddie Mac, which ineligibility continues unremedied for a period of 90 days. then, and in each and every such case, subject to applicable law, so long as an Event of Default shall not have been remedied, either the Trustee or the holders of Certificates evidencing in the aggregate not less than 66 2/3% of the aggregate Voting Interest represented by all Certificates, by notice in writing to the Master Servicer (and to the Trustee if given by the Certificateholders) may terminate all of the rights and obligations of the Master Servicer under this Agreement and in and to the Mortgage Loans, but without prejudice to any rights which the Master Servicer may have to the aggregate Master Servicing Fees due prior to the date of transfer of the Master Servicer's responsibilities hereunder, reimbursement of expenses to the extent permitted by this Agreement, Periodic Advances and other advances of its own funds. Upon receipt by the Master Servicer of such written notice, all authority and power of the Master Servicer under this Agreement, whether with respect to the Certificates or the Mortgage Loans or otherwise, shall pass to and be vested in the Trustee pursuant to and under this Section, subject to the provisions of Section 7.05; and, without limitation, the Trustee is hereby authorized and empowered to execute and deliver, on behalf of the Master Servicer, as attorney-in-fact or otherwise, any and all documents and other instruments, and to do or accomplish all other acts or things necessary or appropriate to effect the purposes of such notice of termination, whether to complete the transfer and endorsement or assignment of the Mortgage Loans and related documents or otherwise. The Master Servicer agrees to cooperate with the Trustee in effecting the termination of the Master Servicer's responsibilities and rights hereunder and shall promptly provide the Trustee all documents and records reasonably requested by it to enable it to assume the Master Servicer's functions hereunder and shall promptly also transfer to the Trustee all amounts which then have been or should have been deposited in the Certificate Account by the Master Servicer or which are thereafter received by the Master Servicer with respect to the Mortgage Loans. SECTION 7.02 OTHER REMEDIES OF TRUSTEE. During the continuance of any Event of Default, so long as such Event of Default shall not have been remedied, the Trustee, in addition to the rights specified in Section 7.01, shall have the right, in its own name as trustee of an express trust, to take all actions now or hereafter existing at law, in equity or by statute to enforce its rights and remedies and to protect the interests, and enforce the rights and remedies, of the Certificateholders (including the institution and prosecution of all judicial, administrative and other proceedings and the filing of proofs of claim and debt in connection therewith). Except as otherwise expressly provided in this Agreement, no remedy provided for by this Agreement shall be exclusive of any other remedy, and each and every remedy shall be cumulative and in addition to any other remedy and no delay or omission to exercise any right or remedy shall impair any such right or remedy or shall be deemed to be a waiver of any Event of Default. SECTION 7.03 DIRECTIONS BY CERTIFICATEHOLDERS AND DUTIES OF TRUSTEE DURING EVENT OF DEFAULT. During the continuance of any Event of Default, Holders of Certificates evidencing in the aggregate not less than 25% of the aggregate Voting Interest represented by all Certificates may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Agreement; provided, however, that the Trustee shall be under no obligation to pursue any such remedy, or to exercise any of the rights or powers vested in it by this agreement (including, without limitation, (i) the conducting or defending of any administrative action or litigation hereunder or in relation hereto and (ii) the terminating of the Master Servicer from its rights and duties as servicer hereunder) at the request, order or direction of any of the Certificateholders, unless such Certificateholders shall have offered to the Trustee reasonable security or indemnity against the cost, expenses and liabilities which may be incurred therein or thereby and, provided further, that, subject to the provisions of Section 8.01, the Trustee shall have the right to decline to follow any such direction if the Trustee, in accordance with an Opinion of Counsel, determines that the action or proceeding so directed may not lawfully be taken or if the Trustee in good faith determines that the action or proceeding so directed would involve it in personal liability or be unjustly prejudicial to the nonassenting Certificateholders. SECTION 7.04 ACTION UPON CERTAIN FAILURES OF THE MASTER SERVICER AND UPON EVENT OF DEFAULT. In the event that the Trustee shall have knowledge of any failure of the Master Servicer specified in Section 7.01(i) or (ii) which would become an Event of Default upon the Master Servicer's failure to remedy the same after notice, the Trustee may, but need not if the Trustee deems it not in the Certificateholders' best interest, give notice thereof to the Master Servicer. For all purposes of this Agreement, in the absence of actual knowledge by a corporate trust officer of the Trustee, the Trustee shall not be deemed to have knowledge of any failure of the Master Servicer as specified in Section 7.01(i) and (ii) or any Event of Default unless notified thereof in writing by the Master Servicer or by a Certificateholder. SECTION 7.05 TRUSTEE TO ACT; APPOINTMENT OF SUCCESSOR. When the Master Servicer receives notice of termination pursuant to Section 7.01 or the Trustee receives the resignation of the Master Servicer evidenced by an Opinion of Counsel pursuant to Section 6.04, the Trustee shall be the successor in all respects to the Master Servicer in its capacity as master servicer under this Agreement and the transactions set forth or provided for herein and shall have the rights and powers and be subject to all the responsibilities, duties and liabilities relating thereto placed on the Master Servicer by the terms and provisions hereof and in its capacity as such successor shall have the same limitation of liability herein granted to the Master Servicer. In the event that the Trustee is succeeding to the Master Servicer as the Master Servicer, as compensation therefor, the Trustee shall be entitled to receive monthly such portion of the Master Servicing Fee, together with such other servicing compensation as is agreed to at such time by the Trustee and the Master Servicer, but in no event more than 25% thereof until the date of final cessation of the Master Servicer's servicing activities hereunder. Notwithstanding the above, the Trustee may, if it shall be unwilling to so act, or shall, if it is unable to so act or to obtain a qualifying bid as described below, appoint, or petition a court of competent jurisdiction to appoint, any housing and home finance institution, bank or mortgage servicing institution having a net worth of not less than $10,000,000 and meeting such other standards for a successor servicer as are set forth herein, as the successor to the Master Servicer hereunder in the assumption of all or any part of the responsibilities, duties or liabilities of the Master Servicer hereunder; provided, however, that until such a successor master servicer is appointed and has assumed the responsibilities, duties and liabilities of the Master Servicer hereunder, the Trustee shall continue as the successor to the Master Servicer as provided above. The compensation of any successor master servicer so appointed shall not exceed the compensation specified in Section 6.05 hereof. In the event the Trustee is required to solicit bids as provided above, the Trustee shall solicit, by public announcement, bids from housing and home finance institutions, banks and mortgage servicing institutions meeting the qualifications set forth in the preceding sentence for the purchase of the master servicing functions. Such public announcement shall specify that the successor master servicer shall be entitled to the full amount of the Master Servicing Fee as compensation together with the other servicing compensation in the form of late reporting fees or otherwise as provided in Section 6.05. Within 30 days after any such public announcement, the Trustee shall negotiate and effect the sale, transfer and assignment of the master servicing rights and responsibilities hereunder to the qualified party submitting the highest qualifying bid. The Trustee shall deduct all costs and expenses of any public announcement and of any sale, transfer and assignment of the servicing rights and responsibilities hereunder from any sum received by the Trustee from the successor to the Master Servicer in respect of such sale, transfer and assignment. After such deductions, the remainder of such sum shall be paid by the Trustee to the Master Servicer at the time of such sale, transfer and assignment to the Master Servicer's successor. The Trustee and such successor shall take such action, consistent with this Agreement, as shall be necessary to effectuate any such succession. The Master Servicer agrees to cooperate with the Trustee and any successor servicer in effecting the termination of the Master Servicer's servicing responsibilities and rights hereunder and shall promptly provide the Trustee or such successor master servicer, as applicable, all documents and records reasonably requested by it to enable it to assume the Master Servicer's function hereunder and shall promptly also transfer to the Trustee or such successor master servicer, as applicable, all amounts which then have been or should have been deposited in the Certificate Account by the Master Servicer or which are thereafter received by the Master Servicer with respect to the Mortgage Loans. Neither the Trustee nor any other successor master servicer shall be deemed to be in default hereunder by reason of any failure to make, or any delay in making, any distribution hereunder or any portion thereof caused by (i) the failure of the Master Servicer to deliver, or any delay in delivering, cash, documents or records to it, or (ii) restrictions imposed by any regulatory authority having jurisdiction over the Master Servicer. Notwithstanding anything to the contrary contained in Section 7.01 above or this Section 7.05, the Master Servicer shall retain all of its rights and responsibilities hereunder, and no successor (including the Trustee) shall succeed thereto, if the assumption thereof by such successor would cause the rating assigned to any Certificates to be revoked, downgraded or placed on credit review status (other than for possible upgrading) by any Rating Agency and the retention thereof by the Master Servicer would avert such revocation, downgrading or review. SECTION 7.06 NOTIFICATION TO CERTIFICATEHOLDERS. Upon any termination of the Master Servicer or appointment of a successor master servicer, in each case as provided herein, the Trustee shall give prompt written notice thereof to Certificateholders at their respective addresses appearing in the Certificate Register. The Trustee shall also, within 45 days after the occurrence of any Event of Default known to the Trustee, give written notice thereof to Certificateholders at their respective addresses appearing in the Certificate Register, unless such Event of Default shall have been cured or waived within said 45 day period. ARTICLE VIII CONCERNING THE TRUSTEE SECTION 8.01 DUTIES OF TRUSTEE. The Trustee, prior to the occurrence of an Event of Default and after the curing of all Events of Default which may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Agreement. In case an Event of Default has occurred (which has not been cured), the Trustee, subject to the provisions of Sections 7.01, 7.03, 7.04 and 7.05, shall exercise such of the rights and powers vested in it by this Agreement, and use the same degree of care and skill in its exercise as a prudent investor would exercise or use under the circumstances in the conduct of such investor's own affairs. The Trustee, upon receipt of all resolutions, certificates, statements, opinions, reports, documents, orders or other instruments furnished to the Trustee, which are specifically required to be furnished pursuant to any provision of this Agreement, shall examine them to determine whether they are in the form required by this Agreement; provided, however, that the Trustee shall not be responsible for the accuracy or content of any certificate, statement, instrument, report, notice or other document furnished by the Master Servicer or the Servicers pursuant to Articles III, IV and IX. No provision of this Agreement shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act or its own willful misconduct; provided, however, that: (i) Prior to the occurrence of an Event of Default and after the curing of all such Events of Default which may have occurred, the duties and obligations of the Trustee shall be determined solely by the express provisions of this Agreement, the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Agreement, no implied covenants or obligations shall be read into this Agreement against the Trustee and, in the absence of bad faith on the part of the Trustee, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee, and conforming to the requirements of this Agreement; (ii) The Trustee shall not be personally liable with respect to any action taken, suffered or omitted to be taken by it in good faith in accordance with the direction of holders of Certificates which evidence in the aggregate not less than 25% of the Voting Interest represented by all Certificates relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Agreement; and (iii) The Trustee shall not be liable for any error of judgment made in good faith by any of its Responsible Officers, unless it shall be proved that the Trustee or such Responsible Officer, as the case may be, was negligent in ascertaining the pertinent facts. None of the provisions contained in this Agreement shall require the Trustee to expend or risk its own funds or otherwise incur personal financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers if there is reasonable ground for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it. SECTION 8.02 CERTAIN MATTERS AFFECTING THE TRUSTEE. Except as otherwise provided in Section 8.01: (i) The Trustee may request and rely and shall be protected in acting or refraining from acting upon any resolution, Officers' Certificate, certificate of auditors or any other certificate, statement, instrument, opinion, report, notice, request, consent, order, appraisal, bond or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties and the manner of obtaining consents and evidencing the authorization of the execution thereof shall be subject to such reasonable regulations as the Trustee may prescribe; (ii) The Trustee may consult with counsel, and any written advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken or suffered or omitted by it hereunder in good faith and in accordance with such advice or Opinion of Counsel; (iii) The Trustee shall not be personally liable for any action taken, suffered or omitted by it in good faith and believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Agreement; (iv) Subject to Section 7.04, the Trustee shall not be accountable, shall have no liability and makes no representation as to any acts or omissions hereunder of the Master Servicer until such time as the Trustee may be required to act as Master Servicer pursuant to Section 7.05 and thereupon only for the acts or omissions of the Trustee as successor Master Servicer; and (v) 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. SECTION 8.03 TRUSTEE NOT REQUIRED TO MAKE INVESTIGATION. Prior to the occurrence of an Event of Default hereunder and after the curing of all Events of Default which may have occurred, the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, appraisal, bond, Mortgage, Mortgage Note or other paper or document (provided the same appears regular on its face), unless requested in writing to do so by holders of Certificates evidencing in the aggregate not less than 51% of the Voting Interest represented by all 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 so proceeding. The reasonable expense of every such investigation shall be paid by the Master Servicer or, if paid by the Trustee shall be repaid by the Master Servicer upon demand. SECTION 8.04 TRUSTEE NOT LIABLE FOR CERTIFICATES OR MORTGAGE LOANS. The recitals contained herein and in the Certificates (other than the certificate of authentication on the Certificates) shall be taken as the statements of the Seller, and the Trustee assumes no responsibility as to the correctness of the same. The Trustee makes no representation for the correctness of the same. The Trustee makes no representation as to the validity or sufficiency of this Agreement or of the Certificates or of any Mortgage Loan or related document. Subject to Section 2.04, the Trustee shall not be accountable for the use or application by the Seller of any of the Certificates or of the proceeds of such Certificates, or for the use or application of any funds paid to the Master Servicer in respect of the Mortgage Loans deposited into the Certificate Account by the Master Servicer or, in its capacity as trustee, for investment of any such amounts. SECTION 8.05 TRUSTEE MAY OWN CERTIFICATES. The Trustee, and any agent thereof, in its individual or any other capacity, may become the owner or pledgee of Certificates with the same rights it would have if it were not Trustee or such agent and may transact banking and/or trust business with the Seller, the Master Servicer or their Affiliates. SECTION 8.06 THE MASTER SERVICER TO PAY FEES AND EXPENSES. The Master Servicer covenants and agrees to pay to the Trustee from time to time, from its own funds, and the Trustee shall be entitled to receive, reasonable compensation (which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust) for all services rendered by it in the execution of the trusts hereby created and in the exercise and performance of any of the powers and duties hereunder of the Trustee and, except as otherwise agreed by the Master Servicer and the Trustee, the Master Servicer will pay or reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by it in accordance with any of the provisions of this Agreement (including the reasonable compensation and the expenses and disbursements of its counsel and of all persons not regularly in its employ) except any such expense, disbursement, or advance as may arise from its negligence or bad faith. The Trustee shall have no right of reimbursement from the Trust Estate for any such expenses, disbursements and advances not paid or reimbursed to it by the Master Servicer. SECTION 8.07 ELIGIBILITY REQUIREMENTS. The Trustee hereunder shall at all times (i) be a corporation or association having its principal office in a state and city acceptable to the Seller, 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 a combined capital and surplus of at least $50,000,000, or shall be a member of a bank holding system, the aggregate combined capital and surplus of which is at least $50,000,000, provided that its separate capital and surplus shall at all times be at least the amount specified in Section 310(a)(2) of the Trust Indenture Act of 1939, (ii) be subject to supervision or examination by federal or state authority and (iii) have a credit rating or be otherwise acceptable to the Rating Agencies such that neither of the Rating Agencies would reduce their respective then current ratings of the Certificates (or have provided such security from time to time as is sufficient to avoid such reduction) as evidenced in writing by each Rating Agency. 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 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, the Trustee shall resign immediately in the manner and with the effect specified in Section 8.08. SECTION 8.08 RESIGNATION AND REMOVAL. The Trustee may at any time resign and be discharged from the trust hereby created by giving written notice of resignation to the Master Servicer, such resignation to be effective upon the appointment of a successor trustee. Upon receiving such notice of resignation, the Master Servicer shall promptly appoint a successor trustee by written instrument, in duplicate, one copy of which instrument shall be delivered to the resigning entity and one copy to its successor. If no successor trustee shall have been appointed and have accepted appointment within 30 days after the giving of such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor trustee. If at any time the Trustee shall cease to be eligible in accordance with the provisions of Section 8.07 and shall fail to resign after written request for its resignation by the Master Servicer, or if at any time the Trustee shall become incapable of acting, or an order for relief shall have been entered in any bankruptcy or insolvency proceeding with respect to such entity, or a receiver of such entity or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of the property or affairs of the Trustee for the purpose of rehabilitation, conversion or liquidation, or the Master Servicer shall deem it necessary in order to change the situs of the Trust Estate for state tax reasons, then the Master Servicer shall remove the Trustee and appoint a successor trustee by written instrument, in duplicate, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee. The Holders of Certificates evidencing in the aggregate not less than 51% of the Voting Interests represented by all Certificates (except that any Certificate registered in the name of the Seller, the Master Servicer or any affiliate thereof will not be taken into account in determining whether the requisite Voting Interests has been obtained) may at any time remove the Trustee and appoint a successor by written instrument or instruments, in triplicate, signed by such holders or their attorneys-in-fact duly authorized, one complete set of which instruments shall be delivered to the Master Servicer, one complete set of which shall be delivered to the entity or entities so removed and one complete set of which shall be delivered to the successor so appointed. Any resignation or removal of the Trustee and appointment of a successor pursuant to any of the provisions of this Section shall become effective upon acceptance of appointment by the successor as provided in Section 8.09. SECTION 8.09 SUCCESSOR. Any successor trustee appointed as provided in Section 8.08 shall execute, acknowledge and deliver to the Master Servicer 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, without any further act, deed or reconveyance, shall become fully vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as trustee herein. The predecessor trustee shall deliver to its successor all Owner Mortgage Loan Files and related documents and statements held by it hereunder (other than any Owner Mortgage Loan Files at the time held by a Custodian, which Custodian shall become the agent of any successor trustee hereunder), and the Seller, the Master Servicer and the predecessor entity 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 shall accept appointment as provided in this Section unless at the time of such acceptance such successor shall be eligible under the provisions of Section 8.07 Upon acceptance of appointment by a successor as provided in this Section, the Master Servicer shall mail notice of the succession of such trustee hereunder to all Holders of Certificates at their addresses as shown in the Certificate Register. If the Master Servicer fails to mail such notice within ten days after acceptance of the successor trustee, the successor trustee shall cause such notice to be mailed at the expense of the Master Servicer. SECTION 8.10 MERGER OR CONSOLIDATION. Any Person into which the Trustee may be merged or converted or with which it may be consolidated, to which it may sell or transfer its corporate trust business and assets as a whole or substantially as a whole or any Person resulting from any merger, sale, transfer, conversion or consolidation to which the Trustee shall be a party, or any Person succeeding to the business of such entity, shall be the successor of the Trustee hereunder; provided, however, that (i) such Person shall be eligible under the provisions of Section 8.07, 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, and (ii) the Trustee shall deliver an Opinion of Counsel to the Seller and the Master Servicer to the effect that such merger, consolidation, sale or transfer will not subject the REMIC to federal, state or local tax or cause the REMIC to fail to qualify as a REMIC, which Opinion of Counsel shall be at the sole expense of the Trustee. SECTION 8.11 AUTHENTICATING AGENT. The Trustee may appoint an Authenticating Agent, which shall be authorized to act on behalf of the Trustee in authenticating Certificates. Wherever reference is made in this Agreement to the authentication of Certificates by the Trustee or the Trustee's countersignature, such reference shall be deemed to include authentication on behalf of the Trustee by the Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by the Authenticating Agent. The Authenticating Agent must be acceptable to the Seller and the Master Servicer and must be a corporation organized and doing business under the laws of the United States of America or of any state, having a principal office and place of business in a state and city acceptable to the Seller and the Master Servicer, having a combined capital and surplus of at least $15,000,000, authorized under such laws to do a trust business and subject to supervision or examination by federal or state authorities. Any corporation into which the Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Authenticating Agent shall be a party, or any corporation succeeding to the corporate agency business of the Authenticating Agent, shall be the Authenticating Agent without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent. The Authenticating Agent may at any time resign by giving at least 30 days' advance written notice of resignation to the Trustee, the Seller and the Master Servicer. The Trustee may at any time terminate the agency of the Authenticating Agent by giving written notice thereof to the Authenticating Agent, the Seller and the Master Servicer. Upon receiving a notice of resignation or upon such a termination, or in case at any time the Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section 8.11, the Trustee promptly shall appoint a successor Authenticating Agent, which shall be acceptable to the Master Servicer, and shall give written notice of such appointment to the Seller, and shall mail notice of such appointment to all Certificateholders. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers, duties and responsibilities of its predecessor hereunder, with like effect as if originally named as Authenticating Agent herein. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section 8.11. The Authenticating Agent shall have no responsibility or liability for any action taken by it as such at the direction of the Trustee. Any reasonable compensation paid to the Authenticating Agent shall be a reimbursable expense under Section 8.06. SECTION 8.12 SEPARATE TRUSTEES AND CO-TRUSTEES. The Trustee shall have the power from time to time to appoint one or more persons or corporations to act either as co-trustees jointly with the Trustee, or as separate trustees, for the purpose of holding title to, foreclosing or otherwise taking action with respect to any Mortgage Loan outside the state where the Trustee has its principal place of business, where such separate trustee or co-trustee is necessary or advisable (or the Trustee is advised by the Master Servicer that such separate trustee or co-trustee is necessary or advisable) under the laws of any state in which a Mortgaged Property is located or for the purpose of otherwise conforming to any legal requirement, restriction or condition in any state in which a Mortgaged Property is located or in any state in which any portion of the Trust Estate is located. The Master Servicer shall advise the Trustee when, in its good faith opinion, a separate trustee or co-trustee is necessary or advisable as aforesaid. The separate trustees or co-trustees so appointed shall be trustees for the benefit of all of the Certificateholders and shall have such powers, rights and remedies as shall be specified in the instrument of appointment; provided, however, that no such appointment shall, or shall be deemed to, constitute the appointee an agent of the Trustee. The Seller and the Master Servicer shall join in any such appointment, but such joining shall not be necessary for the effectiveness of such appointment. Every separate trustee and co-trustee shall, to the extent permitted by law, be appointed and act subject to the following provisions and conditions: (i) all powers, duties, obligations and rights conferred upon the Trustee, in respect of the receipt, custody and payment of moneys shall be exercised solely by the Trustee; (ii) all other rights, powers, duties and obligations conferred or imposed upon the Trustee shall be conferred or imposed upon and exercised or performed by the Trustee and such separate trustee or co-trustee jointly, except to the extent that under any law of any jurisdiction in which any particular act or acts are to be performed (whether as Trustee hereunder or as successor to the Master Servicer hereunder) the Trustee shall be incompetent or unqualified to perform such act or acts, in which event such rights, powers, duties and obligations (including the holding of title to the Trust Estate or any portion thereof in any such jurisdiction) shall be exercised and performed by such separate trustee or co-trustee; (iii) no separate trustee or co-trustee hereunder shall be personally liable by reason of any act or omission of any other separate trustee or co-trustee hereunder; and (iv) the Trustee may at any time accept the resignation of or remove any separate trustee or co-trustee so appointed by it, if such resignation or removal does not violate the other terms of this Agreement. 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, co-trustee, or custodian shall refer to this Agreement and the conditions of this Article. 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 furnished to the Trustee. Any separate trustee, co-trustee, or custodian may, at any time, constitute the Trustee, its agent or attorney-in-fact, with full power and authority, to the extent not prohibited by law, to do any lawful act under or in respect of this Agreement on its behalf and in its name. If any separate trustee or co-trustee shall die, become incapable of acting, resign or be removed, all of its estates, properties, rights, remedies and trusts shall vest in and be exercised by the Trustee to the extent permitted by law, without the appointment of a new or successor trustee. No separate trustee or co-trustee hereunder shall be required to meet the terms of eligibility as a successor trustee under Section 8.07 hereunder and no notice to Certificateholders of the appointment thereof shall be required under Section 8.09 hereof. The Trustee agrees to instruct its co-trustees, if any, to the extent necessary to fulfill such entity's obligations hereunder. The Master Servicer shall pay the reasonable compensation of the co-trustees to the extent, and in accordance with the standards, specified in Section 8.06 hereof. SECTION 8.13 APPOINTMENT OF CUSTODIANS. The Trustee may at any time on or after the Closing Date, with the consent of the Master Servicer and the Seller, appoint one or more Custodians to hold all or a portion of the Owner Mortgage Loan Files as agent for the Trustee, by entering into a Custodial Agreement. Subject to this Article VIII, the Trustee agrees to comply with the terms of each Custodial Agreement and to enforce the terms and provisions thereof against the Custodian for the benefit of the Certificateholders. Each Custodian shall be a depository institution subject to supervision by federal or state authority, shall have a combined capital and surplus of at least $10,000,000 and shall be qualified to do business in the jurisdiction in which it holds any Owner Mortgage Loan File. Each Custodial Agreement may be amended only as provided in Section 10.01(a). SECTION 8.14 TAX MATTERS; COMPLIANCE WITH REMIC PROVISIONS. (a) Each of the Trustee and the Master Servicer covenants and agrees that it shall perform its duties hereunder in a manner consistent with the REMIC Provisions and shall not knowingly take any action or fail to take any action that would (i) affect the determination of the Trust Estate's status as a REMIC; or (ii) cause the imposition of any federal, state or local income, prohibited transaction, contribution or other tax on either the REMIC or the Trust Estate. The Master Servicer, or, in the case of any tax return or other action required by law to be performed directly by the Trustee, the Trustee, shall (i) prepare or cause to be prepared, timely cause to be signed by the Trustee and file or cause to be filed annual federal and applicable state and local income tax returns using a calendar year as the taxable year for the REMIC and the accrual method of accounting; (ii) in the first such federal tax return, make, or cause to be made, elections satisfying the requirements of the REMIC Provisions, on behalf of the Trust Estate, to treat the Trust Estate as a REMIC; (iii) prepare, execute and forward, or cause to be prepared, executed and forwarded, to the Certificateholders all information reports or tax returns required with respect to the REMIC, as and when required to be provided to the Certificateholders, and to the Internal Revenue Service and any other relevant governmental taxing authority in accordance with the REMIC Provisions and any other applicable federal, state or local laws, including without limitation information reports relating to "original issue discount" and "market discount" as defined in the Code based upon the issue prices, prepayment assumption and cash flows provided by the Seller to the Trustee and calculated on a monthly basis by using the issue prices of the Certificates; (iv) make available information necessary for the application of any tax imposed on transferors of residual interests to "disqualified organizations" (as defined in the REMIC Provisions); (v) file Form 8811 and apply for an Employee Identification Number with a Form SS-4 or any other permissible method and respond to inquiries by Certificateholders or their nominees concerning information returns, reports or tax returns; (vi) maintain (or cause to be maintained by the Servicers) such records relating to the REMIC, including but not limited to the income, expenses, individual Mortgage Loans (including REO Mortgage Loans), other assets and liabilities of the REMIC, and the fair market value and adjusted basis of the REMIC property determined at such intervals as may be required by the Code, as may be necessary to prepare the foregoing returns or information reports; (vii) exercise reasonable care not to allow the creation of any "interests" in the REMIC within the meaning of Code Section 860D(a)(2) other than the interests represented by the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-6, Class A-PO, Class A-R, Class B-1, Class B-2, Class B-3, Class B-4, Class B-5 and Class B-6 Certificates; (viii) exercise reasonable care not to allow the occurrence of any "prohibited transactions" within the meaning of Code Section 860F(a), unless the Master Servicer shall have provided an Opinion of Counsel to the Trustee that such occurrence would not (a) result in a taxable gain, (b) otherwise subject either the Trust Estate or the REMIC to tax or (c) cause the Trust Estate to fail to qualify as a REMIC; (ix) exercise reasonable care not to allow the REMIC to receive income from the performance of services or from assets not permitted under the REMIC Provisions to be held by a REMIC; (x) pay (on behalf of the REMIC) the amount of any federal income tax, including, without limitation, prohibited transaction taxes, taxes on net income from foreclosure property, and taxes on certain contributions to a REMIC after the Startup Day, imposed on the REMIC, when and as the same shall be due and payable (but such obligation shall not prevent the Master Servicer or any other appropriate Person from contesting any such tax in appropriate proceedings and shall not prevent the Master Servicer from withholding or depositing payment of such tax, if permitted by law, pending the outcome of such proceedings); and (xi) if required or permitted by the Code and applicable law, act as "tax matters person" for the REMIC within the meaning of Treasury Regulations Section 1.860F-4(d), and the Master Servicer is hereby designated as agent of the Class A-R Certificateholder for such purpose (or if the Master Servicer is not so permitted, the Holder of the Class A-R Certificate shall be the tax matters person in accordance with the REMIC Provisions). The Master Servicer shall be entitled to be reimbursed pursuant to Section 3.02 for any taxes paid by it pursuant to clause (x) of the preceding sentence, except to the extent that such taxes are imposed as a result of the bad faith, willful misfeasance or gross negligence of the Master Servicer in the performance of its obligations hereunder. The Trustee shall sign the tax returns referred to in clause (i) of the second preceding sentence. In order to enable the Master Servicer or the Trustee, as the case may be, to perform its duties as set forth above, the Seller shall provide, or cause to be provided, to the Master Servicer within ten days after the Closing Date all information or data that the Master Servicer 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 each Class of Certificates and the Mortgage Loans in the aggregate. Thereafter, the Seller shall provide to the Master Servicer or the Trustee, as the case may be, promptly upon request therefor, any such additional information or data that the Master Servicer or the Trustee, as the case may be, may from time to time request in order to enable the Master Servicer to perform its duties as set forth above. The Seller hereby indemnifies the Master Servicer or the Trustee, as the case may be, for any losses, liabilities, damages, claims or expenses of the Master Servicer or the Trustee arising from any errors or miscalculations by the Master Servicer or the Trustee pursuant to this Section that result from any failure of the Seller to provide, or to cause to be provided, accurate information or data to the Master Servicer or the Trustee, as the case may be, on a timely basis. The Master Servicer hereby indemnifies the Seller and the Trustee for any losses, liabilities, damages, claims or expenses of the Seller or the Trustee arising from the Master Servicer's willful misfeasance, bad faith or gross negligence in preparing any of the federal, state and local tax returns of the REMIC as described above. In the event that the Trustee prepares any of the federal, state and local tax returns of the REMIC as described above, the Trustee hereby indemnifies the Seller and the Master Servicer for any losses, liabilities, damages, claims or expenses of the Seller or the Master Servicer arising from the Trustee's willful misfeasance, bad faith or negligence in connection with such preparation. (b) Notwithstanding anything in this Agreement to the contrary, each of the Master Servicer and the Trustee shall pay from its own funds, without any right of reimbursement therefor, the amount of any costs, liabilities and expenses incurred by the Trust Estate (including, without limitation, any and all federal, state or local taxes, including taxes imposed on "prohibited transactions" within the meaning of the REMIC Provisions) if and to the extent that such costs, liabilities and expenses arise from a failure of the Master Servicer or the Trustee, respectively, to perform its obligations under this Section 8.14. SECTION 8.15 MONTHLY ADVANCES. In the event that WFHM fails to make a Periodic Advance required to be made pursuant to the WFHM Servicing Agreement on or before the Distribution Date, the Trustee shall make a Periodic Advance as required by Section 3.03 hereof; provided, however, the Trustee shall not be required to make such Periodic Advances if prohibited by law or if it determines that such Periodic Advance would be a Nonrecoverable Advance. With respect to those Periodic Advances which should have been made by WFHM, the Trustee shall be entitled, pursuant to Section 3.02(a)(i), (ii) or (v) hereof, to be reimbursed from the Certificate Account for Periodic Advances and Nonrecoverable Advances made by it. ARTICLE IX TERMINATION SECTION 9.01 TERMINATION UPON PURCHASE BY THE SELLER OR LIQUIDATION OF ALL MORTGAGE LOANS. Subject to Section 9.02, the respective obligations and responsibilities of the Seller, the Master Servicer and the Trustee created hereby (other than the obligation of the Trustee to make certain payments after the Final Distribution Date to Certificateholders and the obligation of the Master Servicer to send certain notices as hereinafter set forth and the tax reporting obligations under Sections 4.05 and 8.14 hereof) shall terminate upon the last action required to be taken by the Trustee on the Final Distribution Date pursuant to this Article IX following the earlier of (i) the purchase by the Seller of all Mortgage Loans and all property acquired in respect of any Mortgage Loan remaining in the Trust Estate at a price equal to the sum of (x) 100% of the unpaid principal balance of each Mortgage Loan (other than any REO Mortgage Loan) as of the Final Distribution Date, and (y) the fair market value of the Mortgaged Property related to any REO Mortgage Loan (as determined by the Master Servicer as of the close of business on the third Business Day next preceding the date upon which notice of any such termination is furnished to Certificateholders pursuant to the third paragraph of this Section 9.01), plus any accrued and unpaid interest through the last day of the month preceding the month of such purchase at the applicable Mortgage Interest Rate less any Fixed Retained Yield on each Mortgage Loan (including any REO Mortgage Loan) and (ii) the final payment or other liquidation (or any advance with respect thereto) of the last Mortgage Loan remaining in the Trust Estate (including for this purpose the discharge of any Mortgagor under a defaulted Mortgage Loan on which a Servicer is not obligated to foreclose due to environmental impairment) or the disposition of all property acquired upon foreclosure or deed in lieu of foreclosure of any Mortgage Loan; provided, however, that in no event shall the trust created hereby continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late ambassador of the United States to the Court of St. James, living on the date hereof. The right of the Seller to purchase all the assets of the Trust Estate pursuant to clause (i) of the preceding paragraph are subject to Section 9.02 and conditioned upon the Pool Scheduled Principal Balance of the Mortgage Loans as of the Final Distribution Date being less than the amount set forth in Section 11.22. In the case of any purchase by the Seller pursuant to said clause (i), the Seller shall provide to the Trustee the certification required by Section 3.04 and the Trustee and the Custodian shall, promptly following payment of the purchase price, release to the Seller the Owner Mortgage Loan Files pertaining to the Mortgage Loans being purchased. Notice of any termination, specifying the Final Distribution Date (which shall be a date that would otherwise be a Distribution Date) upon which the Certificateholders may surrender their Certificates to the Trustee for payment of the final distribution and cancellation, shall be given promptly by the Trustee by letter to Certificateholders mailed not earlier than the 15th day of the month preceding the month of such final distribution and not later than the twentieth day of the month of such final distribution specifying (A) the Final Distribution Date upon which final payment of the Certificates will be made upon presentation and surrender of Certificates at the office or agency of the Trustee therein designated, (B) the amount of any such final payment and (C) that the Record Date otherwise applicable to such Distribution Date is not applicable, payments being made (except in the case of any Class A Certificate surrendered on a prior Distribution Date pursuant to Section 4.01) only upon presentation and surrender of the Certificates at the office or agency of the Trustee therein specified. If the Seller is exercising its right to purchase, the Seller shall deposit in the Certificate Account on or before the Final Distribution Date in immediately available funds an amount equal to the purchase price for the assets of the Trust Estate computed as above provided. Failure to give notice of termination as described herein shall not entitle a Certificateholder to any interest beyond the interest payable on the Final Distribution Date. Upon presentation and surrender of the Certificates, the Trustee shall cause to be distributed to Certificateholders on the Final Distribution Date in proportion to their respective Percentage Interests an amount equal to (i) as to the Classes of Class A Certificates, the respective Principal Balance together with any related Class A Unpaid Interest Shortfall and one month's interest in an amount equal to the respective Interest Accrual Amount, (ii) as to the Classes of Class B Certificates, the respective Principal Balance together with any related Class B Unpaid Interest Shortfall and one month's interest in an amount equal to the respective Interest Accrual Amount and (iii) as to the Class A-R Certificate, the amounts, if any, which remain on deposit in the Certificate Account (other than amounts retained to meet claims) after application pursuant to clauses (i), (ii) and (iii) above and payment to the Master Servicer of any amounts it is entitled as reimbursement or otherwise hereunder. Notwithstanding the foregoing, if the price paid pursuant to clause (i) of the first paragraph of this Section 9.01, after reimbursement to the Servicers, the Master Servicer and the Trustee of any Periodic Advances, is insufficient to pay in full the amounts set forth in clauses (i), (ii) and (iii) of this paragraph, then any shortfall in the amount available for distribution to Certificateholders shall be allocated in reduction of the amounts otherwise distributable on the Final Distribution Date in the same manner as Realized Losses are allocated pursuant to Section 4.02(a) hereof. Such distribution on the Final Distribution Date shall be in lieu of the distribution otherwise required to be made on such Distribution Date in respect of each Class of Certificates. In the event that all of the Certificateholders shall not surrender their Certificates for final payment and cancellation within three months following the Final Distribution Date, the Trustee shall on such date cause all funds, if any, in the Certificate Account not distributed in final distribution to Certificateholders to be withdrawn therefrom and credited to the remaining Certificateholders by depositing such funds in a separate escrow account for the benefit of such Certificateholders. The Trustee shall give a second written notice to the remaining Certificateholders to surrender their Certificates for cancellation and receive the final distribution with respect thereto. If within three 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 on deposit in such escrow account. SECTION 9.02 ADDITIONAL TERMINATION REQUIREMENTS. In the event of a termination of the Trust Estate upon the exercise by the Seller of its purchase option as provided in Section 9.01, the Trust Estate shall be terminated in accordance with the following additional requirements, unless the Trustee has received an Opinion of Counsel to the effect that any other manner of termination (i) will constitute a "qualified liquidation" of the Trust Estate within the meaning of Code Section 860F(a)(4)(A) and (ii) will not subject the REMIC to federal tax or cause the Trust Estate to fail to qualify as a REMIC at any time that any Certificates are outstanding: (i) The notice given by the Master Servicer under Section 9.01 shall provide that such notice constitutes the adoption of a plan of complete liquidation of the REMIC as of the date of such notice (or, if earlier, the date on which the first such notice is mailed to Certificateholders). The Master Servicer shall also specify such date in a statement attached to the final tax return of the REMIC; and (ii) At or after the time of adoption of such a plan of complete liquidation and at or prior to the Final Distribution Date, the Trustee shall sell all of the assets of the Trust Estate to the Seller for cash at the purchase price specified in Section 9.01 and shall distribute such cash within 90 days of such adoption in the manner specified in Section 9.01. ARTICLE X MISCELLANEOUS PROVISIONS SECTION 10.01 AMENDMENT. (a) This Agreement or any Custodial Agreement may be amended from time to time by the Seller, the Master Servicer and the Trustee, without the consent of any of the Certificateholders, (i) to cure any ambiguity or mistake, (ii) to correct or supplement any provisions herein or therein which may be inconsistent with any other provisions herein or therein or in the related Prospectus, (iii) to modify, eliminate or add to any of its provisions to such extent as shall be necessary to maintain the qualification of the Trust Estate as a REMIC at all times that any Certificates are outstanding or to avoid or minimize the risk of the imposition of any federal tax on the Trust Estate or the REMIC pursuant to the Code that would be a claim against the Trust Estate, provided that (a) the Trustee has received an Opinion of Counsel to the effect that 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 shall not, as evidenced by such Opinion of Counsel, adversely affect in any material respect the interests of any Certificateholder, (iv) to change the timing and/or nature of deposits into the Certificate Account provided that such change shall not, as evidenced by an Opinion of Counsel, adversely affect in any material respect the interests of any Certificateholder, (v) to modify, eliminate or add to the provisions of Section 5.02 or any other provisions hereof restricting transfer of the Certificates, provided that the Master Servicer for purposes of Section 5.02 has determined in its sole discretion that any such modifications to this Agreement will neither adversely affect the rating on the Certificates nor give rise to a risk that either the Trust Estate or the REMIC or any of the Certificateholders will be subject to a tax caused by a transfer to a non-permitted transferee and (vi) to make any other provisions with respect to matters or questions arising under this Agreement or such Custodial Agreement which shall not be materially inconsistent with the provisions of this Agreement, provided that such action shall not, as evidenced by an Opinion of Counsel, adversely affect in any material respect the interests of any Certificateholder. Notwithstanding the foregoing, any amendment pursuant to clause (iv) or (vi) shall not be deemed to adversely affect in any material respect the interest of Certificateholders and no Opinion of Counsel to that effect shall be required if the person requesting the amendment instead obtains a letter from each Rating Agency stating that the amendment would not result in the downgrading or withdrawal of the respective ratings then assigned to the Certificates. This Agreement or any Custodial Agreement may also be amended from time to time by the Seller, the Master Servicer and the Trustee and the Holders of Certificates evidencing in the aggregate not less than 66-2/3% of the aggregate Voting Interests of each Class of Certificates affected thereby for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Agreement or such Custodial Agreement or of modifying in any manner the rights of the Holders of Certificates of such Class; provided, however, that no such amendment shall (i) reduce in any manner the amount of, or delay the timing of, payments received on Mortgage Loans which are required to be distributed on any Certificate without the consent of the Holder of such Certificate, (ii) adversely affect in any material respect the interest of the Holders of Certificates of any Class in a manner other than as described in clause (i) hereof without the consent of Holders of Certificates of such Class evidencing, as to such Class, Voting Interests aggregating not less than 66-2/3% or (iii) reduce the aforesaid percentage of Certificates of any Class the Holders of which are required to consent to any such amendment, without the consent of the Holders of all Certificates of such Class then outstanding. Notwithstanding any contrary provision of this Agreement, the Trustee shall not consent to any amendment to this Agreement unless it shall have first received an Opinion of Counsel to the effect that such amendment will not subject the REMIC to tax or cause the Trust Estate to fail to qualify as a REMIC at any time that any Certificates are outstanding. Promptly after the execution of any amendment requiring the consent of Certificateholders, the Trustee shall furnish written notification of the substance of such amendment to each Certificateholder. It shall not be necessary for the consent of Certificateholders under this Section 10.01(a) 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. (b) Notwithstanding any contrary provision of this Agreement, the Master Servicer may, from time to time, amend Schedule I hereto without the consent of any Certificateholder or the Trustee; provided, however, (i) that such amendment does not conflict with any provisions of the related Servicing Agreement, (ii) that the related Servicing Agreement provides for the remittance of each type of Unscheduled Principal Receipts received by such Servicer during the Applicable Unscheduled Principal Receipt Period (as so amended) related to each Distribution Date to the Master Servicer no later than the 24th day of the month in which such Distribution Date occurs and (iii) that such amendment is for the purpose of changing the Applicable Unscheduled Principal Receipt Period for all Mortgage Loans serviced by any Servicer to a Mid-Month Receipt Period with respect to Full Unscheduled Principal Receipts and to a Prior Month Receipt Period with respect to Partial Unscheduled Principal Receipts. A copy of any amendment to Schedule I pursuant to this Section 10.01(b) shall be promptly forwarded to the Trustee. SECTION 10.02 RECORDATION OF AGREEMENT.

The Certificates are limited in right of payment to certain collections and recoveries respecting the Mortgage Loans, all as more specifically set forth herein and in the Agreement. In the event funds are advanced with respect to any Mortgage Loan by a Servicer, the Master Servicer or the Trustee, such advances are reimbursable to such Servicer, the Master Servicer or the Trustee to the extent provided in the Agreement, from related recoveries on such Mortgage Loan or from other cash that would have been distributable to Certificateholders. As provided in the Agreement, withdrawals from the Certificate Account created for the benefit of Certificateholders may be made by the Master Servicer from time to time for purposes other than distributions to Certificateholders, such purposes including reimbursement to a Servicer, the Master Servicer or the Trustee, as applicable, of advances made by such Servicer, the Master Servicer or the Trustee. The Agreement permits, with certain exceptions therein provided, the amendment of the Agreement and the modification of the rights and obligations of the Seller, the Master Servicer and the Trustee and the rights of the Certificateholders under the Agreement at any time by the Seller, the Master 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 Interests of each Class of Certificates affected thereby. Any such consent by the Holder of this Certificate shall be conclusive and binding on such Holder and upon all future holders of this Certificate and of any Certificate issued upon the transfer hereof or in exchange hereof or in lieu hereof whether or not notation of such consent is made upon the Certificate. The Agreement also permits the amendment thereof in certain circumstances without the consent of the Holders of any of the Certificates. As provided in the Agreement and subject to certain limitations therein set forth, the transfer of this Certificate is registrable in the Certificate Register upon surrender of this Certificate for registration of transfer at the office or agency appointed by the Trustee, duly endorsed by, or accompanied by an assignment in the form below or other written instrument of transfer in form satisfactory to the Trustee and the Certificate Registrar, duly executed by the Holder hereof or such Holder's attorney duly authorized in writing, and thereupon one or more new Certificates of authorized Denominations evidencing the same Class and aggregate Percentage Interest will be issued to the designated transferee or transferees.

As provided in the Agreement and subject to certain limitations therein set forth, Certificates are exchangeable for new Certificates of authorized Denominations evidencing the same Class and aggregate Percentage Interest, as requested by the Holder surrendering the same. No service charge will be made for any such registration of transfer or exchange, but the Trustee or the Certificate Registrar may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. The Seller, the Master Servicer, the Trustee and the Certificate Registrar, and any agent of the Seller, the Master Servicer, the Trustee or the Certificate Registrar, may treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and neither the Seller, the Master Servicer, the Trustee, the Certificate Registrar nor any such agent shall be affected by notice to the contrary.

The Agreement permits, but does not require, the Seller to purchase all remaining Mortgage Loans and all property acquired in respect of any Mortgage Loan at a price determined as provided in the Agreement. The exercise of such option will effect early retirement of the Certificates, the Seller's right to exercise such option being subject to the Pool Scheduled Principal Balance of the Mortgage Loans as of the Distribution Date upon which the proceeds of such repurchase are distributed being less than ten percent of the Cut-Off Date Aggregate Principal Balance.

(ii) Prior to the Commencement of Foreclosure in connection with any Mortgage Loan, the Company shall cause (to the extent that the Company as Master Servicer is granted such authority in the related Servicing Agreement) the Servicer to provide the Purchaser with a notice (sent by telecopier) of such proposed and imminent foreclosure, stating the loan number and the aggregate amount owing under the Mortgage Loan. Such notice may be provided to the Purchaser in the form of a copy of a referral letter from such Servicer to an attorney requesting the institution of foreclosure. (b) If requested by the Purchaser, the Company shall cause the Servicer (to the extent that the Company as Master Servicer is granted such authority in the related Servicing Agreement) to make its servicing personnel available (during their normal business hours) to respond to reasonable inquiries, by phone or in writing by facsimile, electronic, or overnight mail transmission, by the Purchaser in connection with any Mortgage Loan identified in a report under subsection (a) (i) (B), (a) (i) (C), (a) (i) (D), or (a) (ii) which has been given to the Purchaser; provided, that (1) the related Servicer shall only be required to provide information that is readily accessible to its servicing personnel and is non-confidential and (2) the related Servicer shall respond within five Business Days orally or in writing by facsimile transmission. (c) In addition to the foregoing, the Company shall cause the Servicer (to the extent that the Company as Master Servicer is granted such authority in the related Servicing Agreement) to provide to the Purchaser such information as the Purchaser may reasonably request provided, however, that such information is consistent with normal reporting practices, concerning each Mortgage Loan that is at least ninety days delinquent and each Mortgage Loan which has become real estate owned, through the final liquidation thereof; provided, that the related Servicer shall only be required to provide information that is readily accessible to its servicing personnel and is non-confidential provided, however, that the Purchaser will reimburse the Company and the related Servicer for any out of pocket expenses. Section 2.02 Purchaser's Election to Delay Foreclosure Proceedings. ----------------------------------------------------- (a) The Purchaser shall be deemed to direct the Company to direct (to the extent that the Company as Master Servicer is granted such authority in the related Servicing Agreement) the related Servicer that in the event that the Company does not receive written notice of the Purchaser's election pursuant to subsection (b) below within 24 hours (exclusive of any intervening non-Business Days) of transmission of the notice provided by the Company under Section 2.01 (a) (ii) subject to extension as set forth in Section 2.02(b), the related Servicer may proceed with the Commencement of Foreclosure in respect of such Mortgage Loan in accordance with its normal foreclosure policies without further notice to the Purchaser. Any foreclosure that has been initiated may be discontinued (i) without notice to the Purchaser if the Mortgage Loan has been brought current or if a refinancing or prepayment occurs with respect to the Mortgage Loan (including by means of a short payoff approved by the related Servicer) or (ii) if the related Servicer has reached the terms of a forbearance agreement with the borrower. In the latter case, the related Servicer may complete such forbearance agreement unless instructed otherwise by the Purchaser within two Business Days notification. (b) In connection with any Mortgage Loan with respect to which a notice under Section 2.01(a)(ii) has been given to the Purchaser, the Purchaser may elect to instruct the Company to cause, to the extent that the Company as Master Servicer is granted such authority in the related Servicing Agreement, the related Servicer to delay the Commencement of Foreclosure until such time as the Purchaser determines that the related Servicer may proceed with the Commencement of Foreclosure. Such election must be evidenced by written notice received within 24 hours (exclusive of any intervening non-Business Days) of transmission of the notice provided by the Company under Section 2.01(a)(ii). Such 24 hour period shall be extended for no longer than an additional four Business Days after the receipt of the information if the Purchaser requests additional information related to such foreclosure; provided, however, that the Purchaser will have at least one Business Day to respond to any requested additional information. Any such additional information shall be provided only to the extent it (i) is not confidential in nature and (ii) is obtainable by the related Servicer from existing reports, certificates or statements or is otherwise readily accessible to its servicing personnel. The Purchaser agrees that it has no right to deal with the mortgagor during such period. However, if such servicing activities include acceptance of a deed-in-lieu of foreclosure or short payoff, the Purchaser will be notified and given two Business Days to respond. (c) With respect to any Mortgage Loan as to which the Purchaser has made an Election to Delay Foreclosure, the Purchaser shall obtain a Current Appraisal as soon as practicable, but in no event more than 15 business days thereafter, and shall provide the Company with a copy of such Current Appraisal. (d) Within two Business Days of making any Election to Delay Foreclosure, the Purchaser shall remit by wire transfer to the Company, for deposit in the Collateral Fund, an amount, as calculated by the Company, equal to the sum of (i) 125% of the greater of the unpaid principal balance of the Mortgage Loan and the value shown in the Current Appraisal referred to in subsection (c) above (or, if such Current Appraisal has not yet been obtained, the Company's estimate thereof, in which case the required deposit under this subsection shall be adjusted upon obtaining such Current Appraisal), and (ii) three months' interest on the Mortgage Loan at the applicable Mortgage Interest Rate. If any Election to Delay Foreclosure extends for a period in excess of three months (such excess period being referred to herein as the "Excess Period"), within two Business Days the Purchaser shall remit by wire transfer in advance to the Company for deposit in the Collateral Fund the amount of each additional month's interest, as calculated by the Company, equal to interest on the Mortgage Loan at the applicable Mortgage Interest Rate for the Excess Period. The terms of this Agreement will no longer apply to the servicing of any Mortgage Loan upon the failure of the Purchaser to deposit any of the above amounts relating to the Mortgage Loan within two Business Days of the Election to Delay Foreclosure or within two Business Days of the commencement of the Excess Period subject to Section 3.01. (e) With respect to any Mortgage Loan as to which the Purchaser has made an Election to Delay Foreclosure, the Company may withdraw from the Collateral Fund from time to time amounts necessary to reimburse the related Servicer for all related Monthly Advances and Liquidation Expenses thereafter made by such Servicer in accordance with the Pooling and Servicing Agreement and the related Servicing Agreement. To the extent that the amount of any such Liquidation Expenses is determined by the Company based on estimated costs, and the actual costs are subsequently determined to be higher, the Company may withdraw the additional amount from the Collateral Fund. In the event that the Mortgage Loan is brought current by the mortgagor and the foreclosure action is discontinued, the amounts so withdrawn from the Collateral Fund shall be redeposited if and to the extent that reimbursement therefor from amounts paid by the mortgagor is not prohibited pursuant to the Pooling and Servicing Agreement or the related Servicing Agreement, applicable law or the related mortgage note. Except as provided in the preceding sentence, amounts withdrawn from the Collateral Fund to cover Monthly Advances and Liquidation Expenses shall not be redeposited therein or otherwise reimbursed to the Purchaser. If and when any such Mortgage Loan is brought current by the mortgagor, all amounts remaining in the Collateral Fund in respect of such Mortgage Loan (after adjustment for all permitted withdrawals and deposits pursuant to this subsection) shall be released to the Purchaser. (f) With respect to any Mortgage Loan as to which the Purchaser has made an Election to Delay Foreclosure, the related Servicer shall continue to service the Mortgage Loan in accordance with its customary procedures (other than the delay in Commencement of Foreclosure as provided herein). If and when the Purchaser shall notify the Company that it believes that it is appropriate to do so, the related Servicer may proceed with the Commencement of Foreclosure. In any event, if the Mortgage Loan is not brought current by the mortgagor by the time the loan becomes 6 months delinquent, the Purchaser's election shall no longer be effective and at the Purchaser's option, either (i) the Purchaser shall purchase the Mortgage Loan from the related Trust Estate at a purchase price equal to the fair market value as shown on the Current Appraisal, to be paid by (x) applying any balance in the Collateral Fund to such to such purchase price, and (y) to the extent of any deficiency, by wire transfer of immediately available funds from the Purchaser to the Company for deposit in the related Certificate Account; or (ii) the related Servicer shall proceed with the Commencement of Foreclosure. (g) Upon the occurrence of a liquidation with respect to any Mortgage Loan as to which the Purchaser made an Election to Delay Foreclosure and as to which the related Servicer proceeded with the Commencement of Foreclosure in accordance with subsection (f) above, the Company shall calculate the amount, if any, by which the value shown on the Current Appraisal obtained under subsection (c) exceeds the actual sales price obtained for the related Mortgaged Property (net of Liquidation Expenses and accrued interest related to the extended foreclosure period), and the Company shall withdraw the amount of such excess from the Collateral Fund, shall remit the same to the Trust Estate and in its capacity as Master Servicer shall apply such amount as additional Liquidation Proceeds pursuant to the Pooling and Servicing Agreement. After making such withdrawal, all amounts remaining in the Collateral Fund in respect of such Mortgage Loan (after adjustment for all permitted withdrawals and deposits pursuant to this Agreement) shall be released to the Purchaser. Section 2.03 Purchaser's Election to Commence Foreclosure Proceedings. -------------------------------------------- (a) In connection with any Mortgage Loan identified in a report under Section 2.01(a)(i)(B), the Purchaser may elect to instruct the Company to cause, to the extent that the Company as Master Servicer is granted such authority in the related Servicing Agreement, the related Servicer to proceed with the Commencement of Foreclosure as soon as practicable. Such election must be evidenced by written notice received by the Company by 5:00 p.m., New York City time, on the third Business Day following the delivery of such report under Section 2.01(a)(i). (b) Within two Business Days of making any Election to Foreclose, the Purchaser shall remit to the Company, for deposit in the Collateral Fund, an amount, as calculated by the Company, equal to 125% of the current unpaid principal balance of the Mortgage Loan and three months interest on the Mortgage Loan at the applicable Mortgage Interest Rate. If and when any such Mortgage Loan is brought current by the mortgagor, all amounts in the Collateral Fund in respect of such Mortgage Loan (after adjustment for all permitted withdrawals and deposits pursuant to this Agreement) shall be released to the Purchaser if and to the extent that reimbursement therefor from amounts paid by the mortgagor is not prohibited pursuant to the Pooling and Servicing Agreement or the related Servicing Agreement, applicable law or the related mortgage note. The terms of this Agreement will no longer apply to the servicing of any Mortgage Loan upon the failure of the Purchaser to deposit the above amounts relating to the Mortgage Loan within two Business Days of the Election to Foreclose subject to Section 3.01. (c) With respect to any Mortgage Loan as to which the Purchaser has made an Election to Foreclose, the related Servicer shall continue to service the Mortgage Loan in accordance with its customary procedures (other than Commencement of Foreclosure as provided herein). In connection therewith, the Company shall have the same rights to make withdrawals for Monthly Advances and Liquidations Expenses from the Collateral Fund as are provided under Section 2.02(e), and the Company shall make reimbursements thereto to the limited extent provided under such subsection in accordance with its customary procedures. The Company shall not be required to cause, to the extent that the Company as Master Servicer is granted such authority in the related Servicing Agreement, the related Servicer to proceed with the Commencement of Foreclosure if (i) the same is stayed as a result of the mortgagor's bankruptcy or is otherwise barred by applicable law, or to the extent that all legal conditions precedent thereto have not yet been complied with, or (ii) the Company believes there is a breach of representations or warranties by the Company, a Servicer, or a Seller, which may result in a repurchase or substitution of such Mortgage Loan, or (iii) the Company or related Servicer reasonably believes the Mortgaged Property may be contaminated with or affected by hazardous wastes or hazardous substances (and, without limiting the related Servicer's right not to proceed with the Commencement of Foreclosure, the Company supplies the Purchaser with information supporting such belief). Any foreclosure that has been initiated may be discontinued (x) without notice to the Purchaser if the Mortgage Loan has been brought current or if a refinancing or prepayment occurs with respect to the Mortgage Loan (including by means of a short payoff approved by the Purchaser) or (y) with notice to the Purchaser if the related Servicer has reached the terms of a forbearance agreement unless instructed otherwise by the Purchaser within two Business Days of such notification. Any such instruction shall be based upon a decision that such forbearance agreement is not in conformity with reasonable servicing practices. (d) Upon the occurrence of a liquidation with respect to any Mortgage Loan as to which the Purchaser made an Election to Foreclose and as to which the related Servicer proceeded with the Commencement of Foreclosure in accordance with subsection (c) above, the Company shall calculate the amount, if any, by which the unpaid principal balance of the Mortgage Loan at the time of liquidation (plus all unreimbursed interest and servicing advances and Liquidation Expenses in connection therewith other than those paid from the Collateral Fund) exceeds the actual sales price obtained for the related Mortgaged Property, and the Company shall withdraw the amount of such excess from the Collateral Fund, shall remit the same to the Trust Estate and in its capacity as Master Servicer shall apply such amount as additional Liquidation Proceeds pursuant to the Pooling and Servicing Agreement. After making such withdrawal, all amounts remaining in the Collateral Fund (after adjustment for all withdrawals and deposits pursuant to subsection (c) in respect of such Mortgage Loan shall be released to the Purchaser.

(b) Except as set forth in 2.04(a), this Agreement and the respective rights, obligations and responsibilities of the Purchaser and the Company hereunder shall terminate upon the later to occur of (i) the final liquidation of the last Mortgage Loan as to which the Purchaser made any Election to Delay Foreclosure or any Election to Foreclose and the withdrawal of all remaining amounts in the Collateral Fund as provided herein and (ii) ten Business Days' notice.

Such obligation shall constitute a general corporate obligation of the Purchaser. The failure to pay such amounts within two Business Days of such demand (except for amounts to cover interest on a Mortgage Loan pursuant to Sections 2.02(d) and 2.03 (b)), shall cause an immediate termination of the Purchaser's right to make any Election to Delay Foreclosure or Election to Foreclose and the Company's obligations under this Agreement with respect to all Mortgage Loans to which such insufficiencies relate, without the necessity of any further notice or demand on the part of the Company.
