5. The second, third and fourth paragraphs of Section 7.01 are hereby amended and restated as follows:

The Trustee shall deliver the written notice to the Servicer of the Event of Default set forth in clause (i) above on any Servicer Remittance Date on which the Servicer fails to make any deposit or payment required pursuant to this Agreement (including but not limited to Advances to the extent required under Section 4.01). Upon termination of the Servicer pursuant to an Event of Default under clause (i) above and assumption of the duties of Servicer by the Trustee, the Back-Up Servicer or other successor servicer appointed pursuant to this Section 7.01 and Section 7.02, such successor servicer shall make any related deposit or payment required pursuant to this Agreement (including but not limited to Advances to the extent required herein) no later than the Distribution Date related to such Servicer Remittance Date. In the event that the Servicer cures any Event of Default under clause (i) above by late deposit or payment of any amount required pursuant to this Agreement and the Trustee, Back-Up Servicer or other successor servicer shall have previously made any or all of such deposit or payment on behalf of the Servicer or in its capacity as successor to such Servicer, the Servicer shall be obligated to reimburse the Trustee, Back-Up Servicer or other successor servicer for the amount of any such deposit or payment plus interest on such amount from the date of deposit or payment by the Trustee, Back-Up Servicer or other successor servicer through the date of reimbursement by the Servicer calculated at a rate equal the prime rate as then published in The Wall Street Journal plus 2.0% per annum. Other than an Event of Default resulting from a failure of the Servicer to make any required Advance, or an Event of Default set forth in clause (v) above, if an Event of Default shall occur and a Responsible Officer of the Trustee has knowledge thereof, then, and in each and every such case, so long as such Event of Default shall not have been remedied, the Trustee, or, solely with respect to an Event of Default set forth in clauses (iv), (x), (xi) or (xii) above, the Depositor, after consulting the Trustee, may, or at the direction of the Holders of Certificates evidencing not less than 51% of the Voting Rights evidenced by the Certificates, the Trustee shall by notice in writing to the Servicer (with a copy to each Rating Agency), terminate all of the rights and obligations of the Servicer under this Agreement and in and to the related Mortgage Loans and the proceeds thereof (other than its rights as a Certificateholder hereunder). With respect to any Event of Default set forth in clauses (iv), (x), (xi), or (xii) above, upon any termination of the Servicer pursuant to this paragraph, DLJMC, in accordance with Section 6.04(b) irrespective of ownership of the related servicing rights, shall appoint the Back-Up Servicer or another successor servicer to become successor servicer; provided that, all obligations and duties of Back-Up Servicer hereunder shall immediately terminate upon appointment of another successor servicer. Any such servicing transfer as a result of any such Event of Default set forth in clauses (iv), (x), (xi) or (xii) shall be accomplished within 60 days from the date the Servicer receives notice of termination (during which time Fairbanks shall continue to be obligated to perform the duties of, and be entitled to the rights and protections provided to, a servicer under this Agreement). In the event Fairbanks is terminated as a result of an Event of Default set forth in clauses (iv), (x), (xi) or (xii) and, at the time of termination, is the owner of the servicing rights for all or a portion of the Fairbanks Mortgage Loans, DLJMC shall purchase those rights at a price determined in accordance with the Schedule. In the event Fairbanks is terminated as a result of an Event of Default set forth in clauses (iv)(b) or (x), the Seller shall reimburse Fairbanks for all unreimbursed Advances and Servicing Advances made by Fairbanks on the date the servicing is transferred to the successor servicer hereunder and the Seller shall be entitled to reimbursement by the successor servicer of any such amounts as and to the extent such amounts are received by the successor servicer under the terms of this Agreement. If an Event of Default results from the failure of the Servicer to make a required Advance or an Event of Default set forth in clause (v) occurs, the Trustee shall, by notice in writing to the Servicer, Back-Up Servicer and the Depositor (with a copy to each Rating Agency), terminate all of the rights and obligations of the Servicer under this Agreement and in and to the related Mortgage Loans and the proceeds thereof, other than its rights as a Certificateholder hereunder. Upon receipt by the Servicer of such written notice of termination, all authority and power of the Servicer under this Agreement, whether with respect to the related Mortgage Loans or otherwise, shall pass to and be vested in (i) the Trustee or its nominee, or, (ii) if Fairbanks is the terminated Servicer, the Back-Up Servicer or its affiliate, or other successor servicer appointed by DLJMC, if DLJMC is the owner of the servicing rights for the related Mortgage Loans or in the case of an Event of Default under clauses (iv), (x), (xi) or (xii) above, in each case subject to Section 7.02; provided, however, that in the case of the assumption of duties as successor servicer by the Back-Up Servicer, the Back-Up Servicer shall not be required to assume such duties as successor servicer until the completion of the transition of servicing from Fairbanks, which transition shall be completed within 60 days of Fairbanks's termination as Servicer during which time Fairbanks shall continue to be obligated to perform the duties of, and be entitled to the rights and protections provided to a servicer under this Agreement. Upon written request from the Trustee, Back-Up Servicer or DLJMC, as applicable, the Servicer shall prepare, execute and deliver to the successor entity designated by the Trustee, the Back-Up Servicer or DLJMC, as applicable, any and all documents and other instruments, place in such successor's possession all related Mortgage Files, and do or cause to be done all other reasonable and customary acts or things necessary or appropriate to effect the purposes of such notice of termination, including but not limited to the transfer and endorsement or assignment of the related Mortgage Loans and related documents, at the Servicer's sole expense or at the expense of DLJMC if the Servicer fails to cover such expenses. In addition, DLJMC, to the extent not reimbursed by the Servicer, shall reimburse the Back-Up Servicer for all of the Back-Up Servicer's reasonable and customary costs and expenses associated with (i) any due diligence, audit or review of the Servicer's servicing operations pursuant to Section 11.01(c) other than the initial due diligence audit and/or review or (ii) any termination of the Servicer, appointment of a successor servicer or the transfer or assumption of servicing upon termination of the Servicer, including but not limited to all costs and expenses (including legal expenses) associated with an evaluation of the potential termination of the Servicer, all costs and expenses associated with the complete transfer of servicing, including the transfer of all servicing files and all servicing data as may be required by the successor servicer to correct any errors or insufficiencies in the servicing data or otherwise to enable the successor servicer to service the Mortgage Loans in accordance with the Agreement; provided, however that in no event shall DLJMC be required to cover any expenses of the Back-Up Servicer incurred in connection with the transfer of servicing to the Back-Up Servicer upon termination of the Servicer in excess of $300,000 in any calendar year, provided that any amounts not reimbursed to the Back-Up Servicer in any calendar year due to application of the $300,000 annual limit shall be reimbursed in subsequent calendar years, subject to the same annual limit. The Servicer shall cooperate with the Trustee and such successor in effecting the termination of the Servicer's responsibilities and rights hereunder, including without limitation, the transfer to such successor for administration by it of all cash amounts which shall at the time be credited by the Servicer to a related Collection Account or Escrow Account or thereafter received with respect to the related Mortgage Loans. The Trustee, Back-Up Servicer or other successor servicer, as applicable, shall thereupon make any Advance to the extent required pursuant to Section 4.01 and subject to the Trustee, Back-Up Servicer or such other successor's determination that such Advance would not constitute a Nonrecoverable Advance or unless prohibited by applicable law. The Trustee, Back-Up Servicer or other successor servicer, as applicable, is hereby authorized and empowered to execute and deliver, on behalf of the 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 related Mortgage Loans and related documents, or otherwise.

6. Section 7.02 is hereby amended and restated as follows: Section 7.02 Trustee to Act; Appointment of Successor. On and after the time the Servicer receives a notice of termination pursuant to Section 7.01 of this Agreement, the Trustee or, if Fairbanks is the terminated Servicer, the Back-Up Servicer, or a successor servicer appointed pursuant to Section 7.01, shall, subject to and to the extent provided herein, either be the successor to the Servicer, but only in its capacity as servicer under this Agreement, and not in any other, and the transactions set forth herein or shall appoint a successor servicer, in either event such successor servicer shall be subject to all the responsibilities, duties and liabilities relating thereto placed on the Servicer by the terms and provisions hereof and applicable law including the obligation to make Advances pursuant to Section 4.01. As compensation therefor, the successor servicer shall be entitled to all funds relating to the related Mortgage Loans that the terminated Servicer would have been entitled to charge to a Collection Account, provided that the terminated Servicer shall nonetheless be entitled to payment or reimbursement as provided in Section 3.09(a) to the extent that such payment or reimbursement relates to the period prior to the completion of the transfer of servicing to a successor servicer. Notwithstanding the foregoing, if the Trustee or the Back-Up Servicer has become the successor to the Servicer in accordance with Section 7.01, the Trustee or Back-Up Servicer may, if it shall be unwilling to so act, or shall, if it is prohibited by applicable law from making Advances pursuant to 4.01 hereof, or if it is otherwise unable to so act, appoint, or petition a court of competent jurisdiction to appoint, any established mortgage loan servicing institution the appointment of which does not adversely affect the then current rating of the Certificates by each Rating Agency, as the successor to the Servicer hereunder in the assumption of all or any part of the responsibilities, duties or liabilities of the Servicer hereunder. Any successor to the Servicer shall be an institution which is a FNMA or FHLMC approved seller/servicer in good standing, which has a net worth of at least $10,000,000, which is willing to service the related Mortgage Loans and which executes and delivers to the Depositor and the Trustee an agreement accepting such delegation and assignment, containing an assumption by such Person of the rights, powers, duties, responsibilities, obligations and liabilities of the Servicer (other than liabilities of the Servicer under Section 6.03 hereof incurred prior to termination of the Servicer under Section 7.01 hereunder), with like effect as if originally named as a party to this Agreement; provided that each Rating Agency acknowledges that its rating of the Certificates in effect immediately prior to such assignment and delegation will not be qualified or reduced as a result of such assignment and delegation. Any successor servicer appointed by DLJMC shall be rated as a servicer of subprime mortgage loans as "average" (or its equivalent) or better by each Rating Agency that maintains a servicer rating system. Pending appointment of a successor to the Servicer hereunder, the Trustee, the Back-Up Servicer or other successor servicer, unless such entity is prohibited by law from so acting, shall, subject to the limitations described herein, act in such capacity as hereinabove provided. In connection with such appointment and assumption, the Trustee may make such arrangements for the compensation of such successor out of payments on the related Mortgage Loans as it and such successor shall agree; provided, however, that no such compensation shall be in excess of the sum of the Servicing Fee and the Back-Up Servicer Fee. The Trustee and such successor shall take such action, consistent with this Agreement, as shall be necessary to effectuate any such succession. Neither the Trustee, the Back-Up Servicer nor any other successor servicer shall be deemed to be in default by reason of any failure to make, or any delay in making, any distribution hereunder or any portio n thereof or any failure to perform, or any delay in performing, any duties or responsibilities hereunder, in either case caused by the failure of the terminated Servicer to deliver or provide, or any delay in delivering or providing, any cash, information, documents or records to it. Any successor to the Servicer shall give notice to the Mortgagors of such change of servicer and shall, during the term of its service as Servicer, maintain in force the policy or policies of the type that the Servicer is required to maintain pursuant to this Agreement.

The Back-Up Servicer will perform an initial on-site due diligence review of the Servicer as related to the Fairbanks Mortgage Loans within a reasonable time following the commencement of the Back-Up Servicer's duties hereunder.

Section 11.04. Limitation of Liability and Indemnification. Neither the Back-Up Servicer, nor any of its directors, officers, employees, or agents shall be under any liability for any action taken or for refraining from the taking of any action in good faith pursuant to this Pooling and Servicing Agreement or for errors in judgment and the Seller hereby indemnifies and hold harmless the Back-Up Servicer and each of its directors, officers, employees and agents, from and against any and all losses, liabilities, claims, charges, damages, fines, penalties, judgments, actions, suits, costs and expenses of any kind or nature whatsoever (including reasonable attorneys' fees and expenses and reasonable fees and expenses of experts) imposed on, incurred by, or asserted against the Back-Up Servicer or any of its directors, officers, employees, agents, or any or their respective successors or assigns, in any way relating to or arising out of this Agreement or any of the transactions contemplated herein; provided, however, that this provision shall not protect the Back-Up Servicer or any such other Person 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 disregard of obligations and duties hereunder. The Back-Up Servicer and any director, officer, employee, or agent thereof shall be entitled to rely in good faith on any document of any kind prima facie properly executed and submitted by any Person respecting any matters arising hereunder. The Seller's obligation to indemnify the Back-Up Servicer hereunder shall be limited to a cap of $100,000 for each calendar year for any loss, liability, claims, charges, damages, fines, penalties, judgments, actions, suits, costs and such other expenses incurred by the Back-Up Servicer during such calendar year; provided that any amounts not paid to Back-Up Servicer in any calendar year due to application of such cap shall be paid in subsequent calendar years, subject to the same annual cap.
