provided, however, that as to any Mortgage Loan, if as evidenced by an Opinion of Counsel delivered to and in form and substance satisfactory to the Indenture Trustee, the Insurer, and the Rating Agencies (x) an optical image or other representation of the related document specified in clause (b)(ii)(C) above is enforceable in the relevant jurisdictions to the same extent as the original of such document and (y) such optical image or other representation does not impair the ability of an owner of such Mortgage Loan to transfer or perfect its interest in such Mortgage Loan, such optical image or other representation may be delivered as required in clause (b)(ii).

     The Seller and the Depositor each hereby confirms to the Indenture Trustee and the Insurer that it has made the appropriate entries in its general accounting records, to indicate that such Mortgage Loans have been sold to the Depositor by the Seller, and sold by the Depositor to the Depositor, and sold by the Depositor to the Indenture Trustee, acting on behalf of the Trust. The Servicer hereby confirms to the Indenture Trustee and the Insurer that it has clearly and unambiguously made appropriate entries in its general accounting records indicating that such Mortgage Loans constitute part of the Trust and are serviced by it on behalf of the Trust in accordance with the terms hereof.

     The Seller shall deliver to the Indenture Trustee, as initial custodian and bailee for the benefit of the Trust, the documents and instruments listed above in this clause (b).

     The Assignments of Mortgage will be held by the Indenture Trustee, subject to the conditions provided in the immediately preceding paragraph.

     The Seller, at its expense shall within 90 days of its delivery of the Mortgage Notes and the Related Documents to the Indenture Trustee, submit to the appropriate recording offices Assignments of Mortgage to the Indenture Trustee on behalf of the Trust, which may be blanket assignments if permitted by applicable law, for the Mortgage Loans. In lieu of recording any such Assignments of Mortgage, the Seller, at its expense, may provide to the Indenture Trustee and the Insurer, an Opinion of Counsel in a form reasonably acceptable to the Indenture Trustee and the Insurer, to the effect that recordation of an Assignment of Mortgage in the state where the related Mortgaged Property is located is not necessary to protect the interests of the Indenture Trustee or the Class A Noteholders in the related Mortgage on or within 90 days after the Closing Date. In the event that any such Assignment of Mortgage is lost or returned unrecorded because of a defect therein, the Seller, at its own expense, shall promptly prepare a substitute Assignment of Mortgage or cure such defect, as the case may be, and thereafter the Seller shall be required to submit each such Assignment of Mortgage for recording. Any failure of the Seller to comply with this Section shall result in the obligation of the Seller to purchase such Mortgage Loans pursuant to the provisions of Section 2.04 or substitute for the related Mortgage Loans pursuant to the provisions of Section 2.05.

     (c) It is the express intent of the parties hereto that the conveyance of the Mortgage Loans and the other property described above by the Depositor to the Trust, as provided in this Agreement be, and be construed as, a sale of all of the Depositor’s right, title and interest in the Mortgage Loans and the other property described above by the Depositor to the Trust. It is, further, not the intention of the parties that such conveyance be deemed a pledge of the Mortgage Loans and the other property described above by the Depositor to the Trust to secure a debt or other obligation of the Depositor. However, in the event that, notwithstanding the intent of the parties, the Mortgage Loans and the other property described above are held to be property of the Depositor, or if for any reason this Agreement is held or deemed to create a security interest in the Mortgage Loans and the other property described above, then, (x) this Agreement shall also be deemed to be a security agreement within the meaning of Articles 8 and 9 of the UCC; and (y) the Depositor hereby grants to the Trust a security interest in and to all of the Depositor’s right, title, and interest, whether now owned or hereafter acquired, in and to the Conveyed Assets.

     The possession by the Indenture Trustee or its designee, of Mortgage Files, including the Mortgage Notes and the Mortgages and such other goods, letters of credit, advices of credit, instruments, money, documents, chattel paper (tangible and electronic) or certificated securities in accordance with the terms of this Agreement shall be deemed to be “possession by the secured party,” or possession by a purchaser or a person designated by him or her, for purposes of perfecting the security interest pursuant to the UCC (including, without limitation, Sections 9-313, 8-313 or 8-321 thereof); and notifications to persons holding such property, and acknowledgments, receipts or confirmations from persons holding such property, shall be deemed to be notifications to, or acknowledgments, receipts or confirmations from, securities intermediaries, bailees or agents of, or persons holding for, the Indenture Trustee or its designee, as applicable, for the purpose of perfecting such security interest under applicable law. The Seller, the Servicer and the Depositor shall, to the extent consistent with this Agreement, take such actions as may be necessary to ensure that, if this Agreement were deemed to create a security interest in the Mortgage Loans and the proceeds thereof, such security interest would be

deemed to be a perfected security interest of first priority under applicable law and will be maintained as such throughout the term of the Agreement. In connection herewith, the Trust shall have all of the rights and remedies of a secured party and creditor under the UCC. Notwithstanding the foregoing, in taking such actions as may be necessary to ensure that, if this Agreement were deemed to create a security interest in the Mortgage Loans and the proceeds thereof, such security interest would be deemed to be a perfected security interest of first priority under applicable law, and maintaining such throughout the term of this Agreement.

     (d) The Indenture Trustee agrees, for the benefit of the Class A Noteholders and the Insurer, within 60 days after the delivery called for in Section 2.01(b)(ii), to review the Mortgage Notes in the case of 2.01(b)(ii)(x) and the Related Documents in the case of 2.01(b)(ii)(y) to ascertain that all documents required to be delivered, solely with respect to Section 2.01(b)(ii)(A)-(E), on such delivery date have been executed and received, and that such documents related to the Mortgage Loans identified on the Mortgage Loan Schedule and that the Assignments of Mortgage have been endorsed as set forth in Section 2.01(b)(ii)(B), and in so doing the Indenture Trustee may rely on the purported due execution and genuineness of any signature thereon. The Indenture Trustee shall be under no duty or obligation to inspect, review or examine any such documents, instruments, certificates or other papers to determine that they are genuine, enforceable, recordable or appropriate for the represented purpose or that they are other than what they purport to be on their face. If within the related 60-day period the Indenture Trustee finds any document constituting a part of a Mortgage File required to be reviewed by it not to have been executed or received (except that the Indenture Trustee will have no responsibility to determine if any title, opinion, binder, policy, legal and vesting document or review meets the requirements of Section 2.01(b)(ii)(D) or the requirements of Section 2.01(b)(ii)(F)) or to be unrelated to the Mortgage Loans identified in said Mortgage Loan Schedule, the Indenture Trustee shall notify the Seller, the Depositor, the Servicer and the Insurer in accordance with the second paragraph of this Section 2.01(d), and the Seller shall have a period of 90 days after such notice within which to correct or cure any such defect; provided, however, that if such defect shall not have been corrected or cured within such 90-day period due primarily to the failure of the related office of real property or other records to return any document constituting a part of a Mortgage File, the Seller shall so notify the Indenture Trustee and the Insurer in writing and the period during which such defect may be corrected or cured shall be extended until such time as any such documents are returned from such related office (in no event, however, will such period extend beyond one (1) year from the date of discovery of such defect); provided, further, that prior to any such extension the Seller shall deliver to the Indenture Trustee a true copy of such document certified by or on behalf of the Seller to be a true and correct copy, the original of which has been transmitted for recordation.

     On or prior to the end of the 60-day period described in the first sentence of this Section 2.01(d), the Indenture Trustee shall deliver to the Seller, the Depositor, the Servicer and the Insurer, an initial certification signed by a Responsible Officer of the Indenture Trustee in the form attached as Exhibit K hereto, and for a period of 90 days thereafter, exception reports every 30 days, in a form acceptable to the Seller and the Indenture Trustee, to the effect that the Indenture Trustee has reviewed the Mortgage Files pursuant to this Section and has determined that all documents required to be reviewed by it (except that the Indenture Trustee will have no responsibility to determine if any title, opinion, binder, policy, legal and vesting document or

review meets the requirements of Section 2.01(b)(ii)(D) or the requirements of Section 2.01(b)(ii)(F)) have been executed and received by the Indenture Trustee, subject to any exceptions identified in such certification. Promptly at the end of the 90-day period described in this paragraph, the Indenture Trustee shall deliver to the Seller, the Depositor, the Servicer and the Insurer, a final certification in the form attached as Exhibit L hereto, as to any remaining document deficiencies.

     (e) The Indenture Trustee shall have no responsibility for reviewing any Mortgage File except as expressly provided in this Section 2.01. In reviewing any Mortgage File pursuant to this Section, the Indenture Trustee shall have no responsibility for determining whether any document is valid and binding, whether the text of any assignment or endorsement is in proper or recordable form (except, if not assigned to the Indenture Trustee or endorsed in blank, to determine if the Indenture Trustee is the assignee or endorsee), whether any document has been recorded in accordance with the requirements of any applicable jurisdiction, or whether a blanket assignment is permitted in any applicable jurisdiction, whether any Person executing any document is authorized to do so or whether any signature thereon is genuine, but shall only be required to determine whether a document has been executed, that it appears regular on its face and is related to such Mortgage Loan, and, upon the return of such document from the county recorder’s office in accordance with this section, that it purports to be recorded.

     (f) The Indenture Trustee shall have the right to appoint a custodian to act on its behalf with respect to its obligations under Section 2.01(d) and (e).

     Section 2.02        Acceptance by Indenture Trustee.

     (a) The Indenture Trustee hereby acknowledges the issuance of the Note Policy by the Insurer for the benefit of the Class A Noteholders and the sale and assignment of the Mortgage Loans, and, subject to the review provided for in Section 2.01, and declares that, when delivered to the Indenture Trustee in accordance with Section 2.01(b), the Indenture Trustee will hold the documents constituting the Mortgage Files and that all amounts received by it under the Indenture in trust, upon the terms herein set forth, for the use and benefit of all present and future Class A Noteholders and the Insurer.

     (b) If the Seller is given notice under Section 2.01(d) and if the Seller does not correct or cure the omission or defect within the 90-day period specified in Section 2.01(d), the Seller shall purchase the Mortgage Loan from the Trust or substitute an Eligible Substitute Mortgage Loan, as provided in Section 2.05, for such Mortgage Loan. Any such purchase by the Seller shall be at the Purchase Price and in each case shall be accomplished in the manner set forth in Section 2.04. It is understood and agreed that the obligation of the Seller to purchase any Mortgage Loan or substitute an Eligible Substitute Mortgage Loan for such Mortgage Loan as to which a material defect in or omission of a constituent document exists shall constitute the sole remedy against the Seller respecting such defect or omission available to the Insurer, the Class A Noteholders, the Indenture Trustee or the Certificateholders.

     The Servicer, promptly following the transfer of (i) a Defective Mortgage Loan from or (ii) an Eligible Substitute Mortgage Loan to the Indenture Trustee pursuant to this Section and Section 2.05, as the case may be, shall amend the Mortgage Loan Schedule and make appropriate

entries in its general account records to reflect such transfer and the addition of any Eligible Substitute Mortgage Loan, if applicable.

Upon discovery by the Seller, the Depositor, the Servicer, the Owner Trustee, the Insurer or the Indenture Trustee (in the case of the Indenture Trustee, upon a Responsible Officer of the Indenture Trustee obtaining actual knowledge) of a breach of any of the foregoing representations and warranties, without regard to any limitation set forth therein concerning the knowledge of the Seller as to the facts stated therein, which materially and adversely affects the value of the related Mortgage Loan or the interests of the Trust, the Class A Noteholders or the Insurer in the related Mortgage Loan, the party discovering such breach shall give prompt written notice to the other parties and the Insurer.

The Purchase Price and any Substitution Adjustments for the purchased Mortgage Loan shall be remitted to the Servicer for deposit in the Collection Account on the Determination Date immediately following such 90-day period, as certified by the Seller to the Indenture Trustee; provided that the Servicer shall remit to the Indenture Trustee, who shall then remit to the Insurer, the portion of the amount, if any, of the Purchase Price referred to in clause (iv) of the definition thereof to the extent such amount is incurred by or imposed on the Insurer. It is understood and agreed that the obligation of the Seller to purchase any Mortgage Loan or substitute an Eligible Substitute Mortgage Loan for such Mortgage Loan as to which a material defect in or omission of a constituent document exists shall constitute the sole remedy against the Seller respecting such defect or omission available to the Insurer, the Class A Noteholders, the Indenture Trustee or the Certificateholders.

     Section 2.05 Substitution of Mortgage Loans.

     (a) On a Determination Date which is on or before the date on which the Seller would otherwise be required to repurchase a Mortgage Loan under Section 2.02 or 2.04, the Seller may deliver to the Trust one or more Eligible Substitute Mortgage Loans in substitution for any one or more of the Defective Mortgage Loans which the Seller would otherwise be required to repurchase pursuant to Sections 2.02 or 2.04. In connection with any such substitution, the Seller shall calculate the Substitution Adjustment, if any, and shall deposit such amount to the Collection Account by 12:00 p.m. New York City time on the third Business Day prior to the Payment Date in the month succeeding the calendar month in which the related cure period expired.

     (b) The Seller shall notify the Servicer, the Insurer and the Indenture Trustee in writing not less than five Business Days before the related Determination Date which is on or before the date on which the Seller would otherwise be required to repurchase such Mortgage Loan pursuant to Section 2.02 or 2.04 of its intention to effect a substitution under this Section 2.05.

Upon receipt of the foregoing, the Indenture Trustee shall release such Defective Mortgage Loan to the Trust and the Trust shall release such Defective Mortgage Loans to the Seller without recourse, representation or warranty.

     (c) Concurrently with the satisfaction of the conditions set forth in Sections 2.05(a) above and the transfer of such Eligible Substitute Mortgage Loans to the Indenture Trustee pursuant to Section 2.05(a), Exhibit A to this Agreement shall be deemed to be amended to exclude all Mortgage Loans being replaced by such Eligible Substitute Mortgage Loans and to

include the information set forth on the Supplemental Mortgage Loan Schedule with respect to such Eligible Substitute Mortgage Loans, and all references in this Agreement to Mortgage Loans shall include such Eligible Substitute Mortgage Loans and be deemed to be made on or after the related substitution date, as the case may be, as to such Eligible Substitute Mortgage Loans.

     (d) As to any Eligible Substitute Mortgage Loan or Loans, the Seller shall cause to be delivered to the Indenture Trustee with respect to such Eligible Substitute Mortgage Loan or Loans such documents and agreements as are required to be held by the Indenture Trustee in accordance with Section 2.01. For any Due Period during which the Seller purchases one or more Defective Mortgage Loans, the Servicer shall determine the amount that shall be deposited by the Seller in the Collection Account at the time of substitution. Any amounts received in respect of the Eligible Substitute Mortgage Loan during the Due Period in which the circumstances giving rise to such substitution occur shall not be a part of the Trust and shall not be deposited by the Servicer in the Collection Account. All amounts received by the Servicer during the Due Period in which the circumstances giving rise to such substitution occur in respect of any Defective Mortgage Loan so removed by the Indenture Trustee shall be deposited by the Servicer in the Collection Account. Upon such substitution, the Eligible Substitute Mortgage Loan shall be subject to the terms of this Agreement in all respects, and the Seller shall be deemed to have made with respect to such Eligible Substitute Mortgage Loan, as of the date of substitution, the covenants, representations and warranties set forth in Section 2.04. The procedures applied by the Seller in selecting each Eligible Substitute Mortgage Loan shall not be materially adverse to the interests of the Indenture Trustee, the Class A Noteholders, the Certificateholders or the Insurer.

     Section 2.06 Tax Treatment. It is the intention of the parties hereto and the Class A Noteholders that the Class A Notes will be indebtedness for federal, state and local income and franchise tax purposes and for purposes of any other tax imposed on or measured by income. The terms of this Agreement shall be interpreted to further the intent of the parties hereto. The parties hereto and each Class A Noteholder (or Class A Note Owner) by acceptance of its Class A Note (or, in the case of a Class A Note Owner, by virtue of such Class A Note Owner’s acquisition of a beneficial interest therein) agrees to treat the Class A Note (or beneficial interest therein), for purposes of federal, state and local income or franchise taxes and any other tax imposed on or measured by income, as indebtedness secured by the Trust Estate and to report the transactions contemplated by this Agreement on all applicable tax returns in a manner consistent with such treatment. Each Class A Noteholder agrees that it will cause any Class A Note Owner acquiring an interest in a Class A Note through it to comply with this Agreement as to treatment of the Class A Notes as indebtedness for federal, state and local income and franchise tax purposes and for purposes of any other tax imposed on or measured by income.

ARTICLE III.

ADMINISTRATION AND SERVICING OF MORTGAGE LOANS

     Section 3.01 The Servicer.

     (a) The Servicer, as independent contract servicer, shall service and administer the Mortgage Loans in accordance with Accepted Servicing Practices and shall have full power and authority, acting alone, to do any and all things in connection with such servicing and administration which the Servicer may deem necessary or desirable and consistent with the terms of this Agreement. The Servicer may enter into Subservicing Agreements for any servicing and administration of Mortgage Loans with any institution which (i) is in compliance with the laws of each state necessary to enable it to perform its obligations under such Subservicing Agreement, (ii) (x) has been designated an approved Seller-Servicer by Freddie Mac or Fannie Mae for first and second mortgage loans or (y) is an affiliate of the Servicer or (z) is otherwise approved by the Insurer. The Servicer shall give written notice to the Insurer and the Indenture Trustee prior to the appointment of any Subservicer. Any such Subservicing Agreement shall be consistent with and not violate the provisions of this Agreement and shall be in form and substance acceptable to the Insurer. The Servicer shall be entitled to terminate any Subservicing Agreement in accordance with the terms and conditions of such Subservicing Agreement and either itself directly service the related Mortgage Loans or enter into a Subservicing Agreement with a successor subservicer which qualifies hereunder.

     (b) Notwithstanding any Subservicing Agreement or any of the provisions of this Agreement relating to agreements or arrangements between the Servicer and a Subservicer or reference to actions taken through a Subservicer or otherwise, the Servicer shall remain obligated and primarily liable for the servicing and administering of the Mortgage Loans in accordance with the provisions of this Agreement without diminution of such obligation or liability by virtue of such Subservicing Agreements or arrangements or by virtue of indemnification from the Subservicer and to the same extent and under the same terms and conditions as if the Servicer alone were servicing and administering the Mortgage Loans. For purposes of this Agreement, the Servicer shall be deemed to have received payments on Mortgage Loans when the Subservicer has received such payments. The Servicer shall be entitled to enter into any agreement with a Subservicer for indemnification of the Servicer by such Subservicer, and nothing contained in this Agreement shall be deemed to limit or modify such indemnification.

     (c) Any Subservicing Agreement that may be entered into and any transactions or services relating to the Mortgage Loans involving a Subservicer in its capacity as such and not as an originator shall be deemed to be between the Subservicer and the Servicer alone, and the Depositor, the Owner Trustee, the Indenture Trustee, the Class A Noteholders, the Certificateholders and the Transferor in respect of the Transferor Interest shall not be deemed parties thereto and shall have no claims, rights, obligations, duties or liabilities with respect to the Subservicer except as set forth in Section 3.01(d) herein. The Servicer shall be solely liable for all fees owed by it to any Subservicer irrespective of whether the Servicer’s compensation pursuant to this Agreement is sufficient to pay such fees.

     (d) In the event the Servicer shall for any reason no longer be the Servicer (including by reason of an Event of Servicing Termination), the Indenture Trustee or its designee approved by the Insurer or a successor Servicer under Section 7.02(a) shall thereupon assume all of the rights and obligations of the Servicer under each Subservicing Agreement that the Servicer may have entered into, unless the Indenture Trustee or designee approved by the Insurer or any successor Servicer elects to terminate any Subservicing Agreement (except with respect to Subservicing Agreements that only allow for termination of the related Subservicer for cause or require a termination fee for termination without cause) in accordance with the terms of such Subservicing Agreement. The Indenture Trustee shall not be responsible for any termination fees under any Subservicing Agreement. In no event shall any Subservicing Agreement require the Insurer or the Indenture Trustee as Successor Servicer to pay compensation to a Subservicer or order the termination of such Subservicer. Any fee payable or expense incurred in connection with such a termination will be payable by the outgoing Servicer. If the Indenture Trustee does not terminate a Subservicing Agreement, the Indenture Trustee, its designee or a successor Servicer shall be deemed to have assumed all of the Servicer’s interest therein and to have replaced the Servicer as a party to each Subservicing Agreement to the same extent as if the Subservicing Agreements had been assigned to the assuming party, except that the Servicer shall not thereby be relieved of any liability or obligations under the Subservicing Agreements with regard to events that occurred prior to the date the Servicer ceased to be the Servicer hereunder. The Servicer, at its expense and without right of reimbursement therefor, shall, upon the request of the Indenture Trustee, deliver to the assuming party all documents and records relating to each Subservicing Agreement and the Mortgage Loans then being serviced and an accounting of amounts collected and held by it and otherwise use its best efforts to effect the orderly and efficient transfer of the Subservicing Agreements to the assuming party.

     (e) No costs incurred by the Servicer or any Subservicer in respect of Servicing Advances shall, for the purposes of payments to the Class A Noteholders and distributions to the Certificateholders, be added to the amount owing under the related Mortgage Loan. Without limiting the generality of the foregoing, the Servicer shall continue, and is hereby authorized and empowered to execute and deliver on behalf of the Trust, each Class A Noteholder and each holder of the Transferor Interest, all instruments of satisfaction or cancellation, or of partial or full release, discharge and all other comparable instruments with respect to the Mortgage Loans and with respect to the Mortgaged Properties. If reasonably required by the Servicer and requested in writing, the Indenture Trustee shall furnish the Servicer and, if directed by a Servicing Officer, any Subservicer with any powers of attorney and other documents reasonably necessary or appropriate to enable the Servicer and any such Subservicer to carry out its servicing and administrative duties under this Agreement.

     (f) On and after such time as the Indenture Trustee receives the resignation of, or notice of the removal of, the Servicer from its rights and obligations under this Agreement, and with respect to resignation pursuant to Section 6.04 herein, after receipt by the Indenture Trustee and the Insurer of the Opinion of Counsel required pursuant to Section 6.04, the Indenture Trustee, if it so elects, and with the consent of the Insurer, shall assume all of the rights and obligations of the Servicer, subject to Section 7.02 herein. The Servicer shall at its expense, deliver to the Indenture Trustee, all documents and records relating to the Mortgage Loans and an accounting of amounts collected and held by the Servicer and otherwise use its best efforts to effect the orderly and efficient transfer of servicing rights and obligations to the assuming party.

     The defaulting Servicer agrees to cooperate with the Indenture Trustee and any successor servicer in effecting the termination of the defaulting Servicer’s responsibilities and rights hereunder as Servicer including, without limitation, notifying each Subservicer of the assignment of the servicing function and providing the Indenture Trustee or its designee all documents and records in electronic or other form reasonably requested by it to enable the Indenture Trustee or its designee to assume the defaulting Servicer’s functions hereunder and the transfer to the Indenture Trustee for administration by it of all amounts which shall at the time be or should have been deposited by the defaulting Servicer in the Collection Account maintained by such defaulting Servicer and any other account or fund maintained with respect to the Class A Notes or thereafter received with respect to the Mortgage Loans. The Servicer being terminated (unless such Servicer is the Indenture Trustee, in which case the initial Servicer) shall bear all costs of a servicing transfer, including but not limited to those of the Indenture Trustee reasonably allocable to specific employees and overhead, legal fees and expenses, accounting and financial consulting fees and expenses, and costs of amending the Transaction Documents, if necessary.

     The Indenture Trustee shall be entitled to be reimbursed from the Servicer (or by the Trust pursuant to Section 5.01(a)(I)(xi), if the Servicer is unable to fulfill its obligations hereunder) for all costs associated with the transfer of servicing from the predecessor Servicer, including, without limitation, any costs or expenses associated with the complete transfer of all servicing data and the completion, correction or manipulation of such servicing data as may be reasonably required by the Indenture Trustee to correct any errors or insufficiencies in the servicing data or otherwise to enable the Indenture Trustee or other successor Servicer to service the Mortgage Loans properly and effectively. If the terminated Servicer does not pay such reimbursement within thirty (30) days of its receipt of an invoice therefore, such reimbursement shall be an expense of the Indenture Trustee pursuant to Section 5.01(a)(I)(xi); provided that the terminated Servicer unless the terminated Servicer is the Indenture Trustee shall reimburse the Trust for any such expense incurred by the Trust.

     (g) The Servicer shall deliver a list of Servicing Officers to the Indenture Trustee and the Insurer on or before the Closing Date and shall revise such list from time to time, as appropriate, and shall deliver all revisions promptly to the Indenture Trustee and the Insurer.

     (h) Consistent with the terms of this Agreement and with respect to HELOCs, the Servicer may consent to the placing of a lien senior to that of the Mortgage on the related Mortgaged Property; provided,

     (i) the Combined Loan-to-Value Ratio, which may be based on a new appraisal, of the related HELOC immediately following the modification is not greater than the Combined Loan-to-Value Ratio of such HELOC as of the date such HELOC was originated; or

     (ii) in the case of any such action that would result in an increase in the Combined Loan-to-Value Ratio over the Combined Loan-to-Value Ratio as of the date such HELOC was originated, the aggregate number of HELOCs with respect to which a

new senior lien is consented to by the Servicer does not exceed 5% of number of HELOCs as of the Cut-Off Date or 30% of the aggregate Principal Balance of the HELOCs as of such date, and the Combined Loan-to-Value Ratio after giving effect to the modification does not exceed 100%.

     The Servicer may also, without approval from the Rating Agencies, Indenture Trustee, or the Insurer, increase the Credit Limit on a Mortgage Loan if such increase is consistent with the Servicer’s underwriting policies and a new Appraised Value is obtained and the Combined Loan-to-Value Ratio of the Mortgage Loan after giving effect to the increase is less than or equal to the Combined Loan-to-Value Ratio of the Mortgage Loan as of the Cut-Off Date. In addition, the Servicer may increase the Credit Limits on up to 10% of the number of Mortgage Loans as of the Cut-Off Date if the increase in the Credit Limit of any single Mortgage Loan does not cause the Combined Loan-to-Value Ratio of such Mortgage Loan to exceed 100%. Notwithstanding anything in this Agreement to the contrary, with respect to a Residential Lot Loan, the Servicer may not make any future advances (except as provided in Section 3.07(c)) and the Servicer shall not (i) permit any modification with respect to any Residential Lot Loan that would change the Loan Rate, reduce, forgive or increase the Stated Principal Balance (except for reductions resulting from actual distributions of principal) or change the final maturity date on such Residential Lot Loan (unless, as provided in Section 3.02(a), the Mortgagor is in default with respect to the Mortgage Loan or such default is, in the judgment of the Servicer, reasonably foreseeable).

     (i) Furthermore, the Servicer, without prior approval from the Rating Agencies, Indenture Trustee or the Insurer, may solicit Mortgagors for a reduction in Margins, provided that the cumulative impact of any such Margin reductions shall not result in the reduction of the weighted average Margin of the Mortgage Loans as of the Cut-Off Date by more than 25 basis points taking into account any prior reductions. In addition, the Servicer may agree to or solicit Mortgagors to change any other terms of the related Mortgage Loans if the changes (i) do not materially and adversely affect the interests of the Class A Noteholders, the Certificateholders, or the Insurer and (ii) are consistent with Accepted Servicing Practices as evidenced by a certificate signed by a Servicing Officer delivered to the Indenture Trustee and the Insurer.

     (j) In no event shall the Servicer modify the maturity of any Mortgage Loan to a maturity that is later than the Final Payment Date. Nothing in this Agreement shall limit the right of the Servicer to solicit mortgagors with respect to new loans (including mortgage loans) that are not Mortgage Loans.

     Section 3.02 Collection of Certain Mortgage Loan Payments.

     (a) The Servicer shall make reasonable efforts to collect all payments called for under the terms and provisions of the Mortgage Loans and shall, to the extent such procedures shall be consistent with this Agreement, follow such collection procedures as it follows with respect to mortgage loans in its servicing portfolio comparable to the Mortgage Loans. Consistent with the foregoing, and without limiting the generality of the foregoing, the Servicer may in its discretion (i) waive any prepayment penalty or late payment charge or any assumption fees or other fees which may be collected in the ordinary course of servicing such Mortgage Loan, (ii) arrange with a Mortgagor a schedule for the payment of principal and interest due and unpaid; provided that

such arrangement is consistent with the Servicer’s policies with respect to the mortgage loans it owns or services; provided, further, that notwithstanding such arrangement such Mortgage Loans will be included in the monthly information delivered by the Servicer to the Indenture Trustee and the Insurer pursuant to Section 5.03 herein or (iii) solely with respect to a Residential Lot Loan, extend the due dates for the Monthly Payments due on the related Mortgage Note for a period of not greater than 180 days; provided, however, that any extension pursuant to clause (iii) shall not affect the amortization schedule of such Residential Lot Loan for purposes of any computation hereunder, except as provided below. In the event of any arrangement pursuant to clause (iii) of this Section 3.01(a), the Servicer shall make timely advances on such Residential Lot Loan during such extension pursuant to Section 3.02(a) and in accordance with the amortization schedule of such Residential Lot Loan without modification thereof by reason of such arrangement. Notwithstanding the foregoing, in the event that any Residential Lot Loan is in default or, in the judgment of the Servicer, such default is reasonably foreseeable, the Servicer, consistent with the standards set forth in Section 3.01, may also waive, modify or vary any term of such Mortgage Loan (including modifications that would change the Loan Rate, forgive the payment of principal or interest or extend the final maturity date of such Residential Lot Loan), accept payment from the related Mortgagor of an amount less than the Stated Principal Balance in final satisfaction of such Residential Lot Loan, or consent to the postponement of strict compliance with any such term or otherwise grant indulgence to any Mortgagor (any and all such waivers, modifications, variances, forgiveness of principal or interest, postponements or indulgences collectively referred to herein as “forbearance”); provided, however, (i) the Servicer shall determine that such forbearance is not materially adverse to the interests of the Class A Noteholders (taking into account any estimated loss that might result absent such action) and is expected to minimize the loss on such Residential Lot Loan, (ii) the Servicer shall not initiate any new lending to such Mortgagor through the Trust Fund and (iii) in no event shall the Servicer grant any such forbearance (other than specifically provided under this Section 3.01(a)) with respect to any one Residential Lot Loan more than once in any twelve (12) month period or more than three times over the life of such Residential Lot Loan. The Servicer’s analysis supporting any forbearance and the conclusion of any forbearance meets the standards of Section 3.01 shall be reflected in writing in the Mortgage File.

     (b) The Servicer may agree to a modification of any Residential Lot Loan (a “Modified Residential Lot Loan”) at the request of the related Mortgagor if (i) the modification is in lieu of a refinancing and the Loan Rate on the Modified Residential Lot Loan, as modified, is approximately a prevailing market rate for newly-originated Residential Lot Loans having similar terms and (ii) the Servicer purchases the Modified Residential Lot Loan from the Trust Fund as described below. Effective immediately after the deposit of the Purchase Price by the Servicer, all interest of the Indenture Trustee in the Modified Residential Lot Loan shall automatically be deemed transferred and assigned to the Servicer and all benefits and burdens of ownership thereof, including the right to accrued interest thereon from the date of the deposit of the Purchase Price and the risk of default thereon, shall pass to the Servicer. The Servicer shall promptly deliver to the Indenture Trustee a certification of a Servicing Officer to the effect that all requirements of this Section 3.07(c) have been satisfied with respect to the Modified Residential Lot Loan. The Servicer shall deposit the Purchase Price for any Modified Residential Lot Loan in the Collection Account pursuant to Section 3.07(c) within one Business

Day after the purchase of the Modified Residential Lot Loan. Upon receipt by the Indenture Trustee of written notification of any such deposit signed by a Servicing Officer, the Indenture Trustee shall release to the Servicer the related Mortgage File and shall execute and deliver such instruments of transfer or assignment, in each case without recourse, as shall be necessary to vest in the Servicer any Modified Residential Lot Loan previously transferred and assigned pursuant hereto.

     (c) The Servicer shall establish and maintain an Eligible Account (the “Collection Account”) entitled “IndyMac Bank, F.S.B., in trust for the registered holders of IndyMac Residential Asset-Backed Trust, Series 2004-LH1, Class A Note, the Class B Certificates, the Class O Certificates and the Transferor Certificates, as their interests may appear, Collection Account.” The Servicer shall notify the Indenture Trustee of the Eligible Institution with which the Collection Account is maintained. The Servicer shall, on the Closing Date, deposit any amounts representing payments on and any collections in respect of the Mortgage Loans received after the Cut-Off Date and prior to the Closing Date (and, with respect to Residential Lot Loans, all payments in respect of such Residential Lot Loan allocable to the period after the Cut-off Date and prior to the Closing Date), and thereafter, subject to Section 3.02(d), deposit within two Business Days following receipt or advance thereof, the following payments and collections received or made by it (without duplication) to the Collection Account:

     (i) all payments received or advanced by the Servicer after the Cut-Off Date on account of principal on the Mortgage Loans, including Principal Prepayments;

     (ii) all payments, net of related servicing fees, received or advanced by the Servicer after the Cut-Off Date on account of interest on the Mortgage Loans;

     (iii) all Net Recoveries;

     (iv) any Advances, as required pursuant to Section 3.19;

     (v) any amounts required to be deposited pursuant to Section 3.07 in connection with any REO Property;

     (vi) any amounts to be paid in connection with a purchase of Mortgage Loans and REO Properties pursuant to Section 10.01;

     (vii) any Compensating Interest to be deposited pursuant to Section 3.20 in connection with any Prepayment Interest Shortfall;

     (viii) any amounts required to be deposited pursuant to Section 5.08(e) in connection with any losses realized on investments with respect to funds held in the Collection Account, the Reinvestment Account and the Revolving Period Funding Account;

     (ix) the Purchase Price of any Mortgage Loan and the amount of any Substitution Adjustment paid by a Seller during the related Due Period pursuant to Sections 2.02, 2.04 and 2.09;

     (x) all Released Mortgaged Property Proceeds; and

     (xi) [Reserved];

     (xii) any amount required to be deposited therein pursuant to Sections 3.02(d) and 5.08(e) herein;

     The foregoing requirements respecting deposits to the Collection Account are exclusive, it being understood that, without limiting the generality of the foregoing, the Servicer need not deposit in the Collection Account amounts representing fees (including annual fees, assumption fees, modification fees, insufficient funds charges and other ancillary income) or late charge penalties payable by Mortgagors or amounts received by the Servicer for the accounts of Mortgagors for application toward the payment of taxes, insurance premiums, assessments and similar items.

     (d) All funds in the Collection Account shall be held (i) uninvested or (ii) invested pursuant to Section 5.08. Any investment earnings on funds held in the Collection Account shall be for the account of the Servicer and may be withdrawn from the Collection Account by the Servicer at any time. Any investment losses on funds held in the Collection Account through the second day preceding the day on which such funds are to be deposited in the Payment Account shall be for such account of the Servicer and promptly (and in no event later than the next Payment Date) upon the realization of such loss shall be deposited by the Servicer to the Collection Account. Any references herein to amounts on deposit in the Collection Account shall refer to amounts net of such investment earnings.

     (e) Notwithstanding anything contained in Section 3.02(b) to the contrary, the Servicer shall be permitted to remit the collections that would otherwise be required to be deposited on a daily basis pursuant to Section 3.02(b), net of any amount permitted to be withdrawn pursuant to Section 3.03(ii) through (vi) hereof, to the Collection Account in immediately available funds no later than 12:00 p.m. New York City time on the Servicer Remittance Date but only for so long as no Deposit Event shall have occurred and be continuing.

     (f) During the period that the Servicer is permitted to remit collections as contemplated by the preceding paragraph 3.02(d), the Servicer shall establish and maintain for the Trust a Mortgage Loan payment record on which the payments and collections in respect of the Mortgage Loans for each of the categories specified in Section 3.02(b) shall be recorded and on which each of the categories of withdrawal specified in Section 3.03 shall be recorded and the Servicer shall notify the Indenture Trustee and the Insurer in writing as promptly as practicable (but in any event not later than the Determination Date for the next Payment Date) of the amounts so recorded for each of the categories specified in such Section that are to be included in Interest Collections and Principal Collections for the related Payment Date and of the amounts so recorded which will constitute a part of Interest Collections and Principal Collections for the Payment Date after the immediately following Payment Date.

     (g) If (i) the written notification called for by the preceding paragraph is not received by the Determination Date for the next Payment Date or (ii) such notification indicates that Interest Collections and Principal Collections for such Payment Date are less than the

Guaranteed Principal Payment Amount and the Class A Interest Payment Amount for such Payment Date or (iii) the Servicer shall fail to make the deposit pursuant to Section 3.02(d), the Indenture Trustee shall immediately notify the Seller, the Depositor and the Insurer.

     Section 3.03 Withdrawals from the Collection Account. The Servicer shall withdraw or cause to be withdrawn funds from the Collection Account for the stated purposes in the following order of priority:

     (i) to reimburse the Servicer for any accrued and unpaid Servicing Fees and, with respect to Residential Lot Loans, to reimburse the Servicer for (a) any unreimbursed Advances to the extent of amounts received which represent Late Collections (net of the related Servicing Fees) of Monthly Payments, Liquidation Proceeds and Insurance Proceeds on Residential Lot Loans with respect to which such Advances were made in accordance with the provisions of Section 3.19(b) or (b) any unreimbursed Advances with respect to the final liquidation of a Residential Lot Loan that are Nonrecoverable Advances, but only to the extent that Late Collections, Liquidation Proceeds, Subsequent Recoveries and Insurance Proceeds received with respect to such Residential Lot Loan are insufficient to reimburse the Servicer for such unreimbursed Advances;

     (ii) on each Servicer Remittance Date, to transfer the following amounts to the Indenture Trustee for deposit in the Payment Account:

     (A) the portion of the Interest Collections and Principal Collections for the related Due Period then in the Collection Account;

     (B) any Advances, as required pursuant to Section 3.19;

     (C) any amounts required to be deposited pursuant to Section 3.07 in connection with any REO Property;

     (D) any amounts to be paid in connection with a purchase of Mortgage Loans and REO Properties pursuant to Section 10.01;

     (E) any Compensating Interest to be deposited pursuant to Section 3.20 in connection with any Prepayment Interest Shortfall;

     (iii) to withdraw any amount received from a Mortgagor that is recoverable and sought to be recovered as a voidable preference by a trustee in bankruptcy pursuant to the United States Bankruptcy Code in accordance with a final, nonappealable order of a court having competent jurisdiction;

     (iv) to make investments in accordance with Section 5.08 and to pay to the Servicer interest earned in respect of such investments or on funds deposited in the Collection Account;

     (v) to pay the Servicer as servicing compensation (in addition to the Servicing Fee) on the Servicer Remittance Date any interest or investment income earned on funds deposited in the Collection Account;

     (vi) to withdraw any funds deposited in the Collection Account that were not required to be deposited therein or were deposited therein in error and to pay such funds to the appropriate Person;

     (vii) to pay the Servicer the servicing compensation for the related Due Period that it is entitled to receive pursuant to Section 3.09 herein to the extent not retained or distributed pursuant to Section 3.02(b) hereof;

     (viii) to reimburse the Servicer for any Advance or Servicing Advance previously made which the Servicer has determined to be a Nonrecoverable Advance;

     (ix) to pay itself any Prepayment Interest Excess;

     (x) to withdraw funds necessary for the conservation and disposition of REO Property pursuant to Section 3.07 to the extent not advanced by the Servicer; and

     (xi) to clear and terminate the Collection Account upon the termination of this Agreement and to pay any amounts remaining therein to the Transferor.

     Prior to making any withdrawal from the Collection Account pursuant to subclause (vii), the Servicer shall have delivered to the Indenture Trustee and the Insurer a certificate of a Servicing Officer indicating the amount of any previous Advance or Servicing Advance determined by the Servicer to be a Nonrecoverable Advance and identifying the related Mortgage Loans(s), and their respective portions of such Nonrecoverable Advance.

     Section 3.04 Maintenance of Hazard Insurance; Property Protection Expenses. The Servicer verifies the existence at the origination of each HELOC fire and hazard insurance naming the Servicer or its designee as loss payee thereunder providing extended coverage in an amount which is at least equal to the lesser of (i) the maximum insurable value of the improvements securing such HELOC from time to time, (ii) the combined principal balance owing on such HELOC and any mortgage loan senior to such HELOC and (iii) the minimum amount required to compensate for damage or loss on a replacement cost basis. The Servicer shall also maintain on property acquired upon foreclosure, or by deed in lieu of foreclosure, fire and hazard insurance with extended coverage in an amount which is at least equal to the lesser of (i) the maximum insurable value from time to time of the improvements which are a part of such property, (ii) the combined principal balance owing on such HELOC and any mortgage loan senior to such HELOC at the time of such foreclosure, or deed in lieu of foreclosure plus accrued interest and the good-faith estimate of the Servicer of related Servicing Advances to be incurred in connection therewith. Amounts collected by the Servicer under any such policies shall be deposited in the Collection Account to the extent called for by Section 3.02. In cases in which any Mortgaged Property is located in an area identified in a federally designated flood area, the hazard insurance to be maintained for the related HELOC shall include flood insurance to the extent such flood insurance is available and the Servicer has determined such insurance to be necessary in accordance with Accepted Servicing Practices of prudent lending institutions. All such flood insurance shall be in amounts not less than the lesser of (A) the amount in clause (i) above, (B) the amount in clause (ii) above and (C) the maximum amount of insurance available under the National Flood Insurance Reform Act of 1994, as amended. The Servicer shall be

under no obligation to require that any Mortgagor maintain earthquake or other additional insurance and shall be under no obligation itself to maintain any such additional insurance on property acquired in respect of a HELOC, other than pursuant to such applicable laws and regulations as shall at any time be in force and as shall require such additional insurance.

     Section 3.05 Maintenance of Mortgage Impairment Insurance Policy. In the event that the Servicer shall obtain and maintain a blanket insurance policy consistent with Accepted Servicing Practices, insuring against fire and hazards of extended coverage on all of the Mortgage Loans, then, to the extent such insurance policy names the Servicer or its designee as loss payee and provides coverage in an amount equal to the aggregate unpaid principal balance on the Mortgage Loans without coinsurance, and otherwise complies with the requirements of Section 3.04, the Servicer shall be deemed conclusively to have satisfied its obligations with respect to fire and hazard insurance coverage under Section 3.04. Upon the request of the Insurer or the Indenture Trustee, the Servicer shall cause to be delivered to the Insurer or the Indenture Trustee, as the case may be, a certified true copy of such insurance policy. In connection with its activities as administrator and servicer of the Mortgage Loans, the Servicer agrees to prepare and present, on behalf of itself, the Indenture Trustee, the Insurer and the Trust, claims under any such insurance policy in a timely fashion in accordance with the terms of such insurance policy.

     Section 3.06 Maintenance of Fidelity Bond and Errors and Omissions Insurance. The Servicer shall maintain with responsible companies, at its own expense, a blanket fidelity bond (“Fidelity Bond”) and an errors and omissions insurance policy (“Errors and Omissions Insurance Policy”), with broad coverage on all officers, employees or other persons acting in any capacity requiring such persons to handle funds, money, documents or papers relating to the related Mortgage Loans (“Servicer Employees”). Any such Fidelity Bond and Errors and Omissions Insurance Policy shall be in the form of the Mortgage Banker’s Blanket Bond and shall protect and insure the Servicer against losses, including forgery, theft, embezzlement, fraud, errors and omissions and negligent acts of the Servicer Employees. Such Fidelity Bond and Errors and Omissions Insurance Policy also shall protect and insure the Servicer against losses in connection with the release or satisfaction of a related Mortgage Loan without having obtained payment in full of the indebtedness secured thereby. No provision of this Section 3.06 requiring such Fidelity Bond and Errors and Omissions Insurance Policy shall diminish or relieve the Servicer from its duties and obligations as set forth in this Agreement. The minimum coverage under any such bond and insurance policy shall be at least equal to the corresponding amounts required by Fannie Mae. Upon the request of the Indenture Trustee or the Insurer, the Servicer shall cause to be delivered to the Indenture Trustee or the Insurer a certificate of insurance of the insurer and the surety including a statement from the surety.

     Section 3.07 Management of and Realization upon Defaulted Mortgage Loans.

     (a) Management of REO Property. The Servicer shall manage, conserve, protect and operate each REO Property for the Trust solely for the purpose of its prudent and prompt disposition and sale. The Servicer shall, either itself or through an agent selected by the Servicer, manage, conserve, protect and operate the REO Property in the same manner that it manages, conserves, protects and operates other foreclosed property for its own account, and in the same manner that similar property in the same locality as the REO Property is managed. The Servicer shall attempt to sell the same (and may temporarily rent the same) on such terms and conditions as the Servicer deems to be in the best interest of the Insurer, the Class A Noteholders and the Trust.

     The Servicer shall cause to be deposited, within the time period specified in Section 3.02(b) or 3.02(d), as applicable, in the Collection Account, all revenues net of Servicing Advances (and in the case of Residential Lot Loans, net of Advances) received with respect to the related REO Property and shall retain, or cause to be withdrawn therefrom, funds necessary for the proper operation, management and maintenance of the REO Property and the fees of any managing agent acting on behalf of the Servicer.

     The disposition of REO Property shall be carried out by the Servicer for cash at such price, and upon such terms and conditions, as the Servicer deems to be in the best interest of the Class A Noteholders, the Trust and the Insurer and, as soon as practicable thereafter, the expenses of such sale shall be paid. The cash proceeds of the sale of the REO Property shall be promptly deposited in the Collection Account, pursuant to Section 3.02(b) or 3.02(d), as applicable, net of any related unreimbursed Servicing Advances and Advances (without duplication of amounts paid pursuant to Section 3.03(vii)), payable to the Servicer in accordance with Section 3.03, for payment in accordance with Section 5.01 herein.

     (b) Realization Upon Defaulted Mortgage Loans. The Servicer shall foreclose upon or otherwise comparably convert to ownership Mortgaged Properties securing such of the Mortgage Loans as come into and continue in default when no satisfactory arrangements can be made for collection of delinquent payments pursuant to Section 3.01, subject to the provisions contained in the second succeeding paragraph of this Section 3.07 and only if the Servicer determines that there is sufficient equity in the related Mortgaged Property to justify such foreclosure. In connection with foreclosure or other conversion, the Servicer will follow Accepted Servicing Practices, including the practice that the Servicer will not be required to expend its own funds in connection with foreclosure or other conversion, correction of default on a related senior mortgage loan or restoration of any Mortgaged Property unless, in its sole judgment, foreclosure, correction or restoration will increase net liquidation proceeds and that, in the event that the related Mortgaged Property shall have suffered damage from an Uninsured Cause, the Servicer shall not be required to expend its own funds toward the restoration of such Mortgaged Property unless it shall determine in its discretion that such restoration will increase the proceeds of liquidation of the Mortgage Loan after reimbursement to itself for such expenses.

     In the event that title to any Mortgaged Property is acquired in foreclosure or by deed in lieu of foreclosure, the deed or certificate of sale shall be issued to the Indenture Trustee or its nominee on behalf of the Trust and the Insurer.

     If the Servicer has actual knowledge that a Mortgaged Property which the Servicer is contemplating acquiring in foreclosure or by deed in lieu of foreclosure is located within 1 mile of any site with environmental or hazardous waste risks, the Servicer will notify the Insurer prior to acquiring the Mortgaged Property and shall not take any action without prior written approval of the Insurer.

     Section 3.08 Indenture Trustee to Cooperate. Upon the payment in full of any Mortgage Loan, the Servicer is authorized to execute, pursuant to the authorization contained in Section 3.01(e), if the related Assignment of Mortgage has been recorded, an instrument of satisfaction regarding the related Mortgage, which instrument of satisfaction shall be recorded by the Servicer if required by applicable law and be delivered to the Person entitled thereto. It is understood and agreed that no expenses incurred in connection with such instrument of satisfaction or transfer shall be reimbursed from amounts deposited in the Collection Account. If the Indenture Trustee is holding any portion of the Mortgage Files, from time to time and as appropriate for the servicing or foreclosure of any Mortgage Loan, the Indenture Trustee shall, upon request of the Servicer and delivery to the Indenture Trustee of a request for release, in the form attached hereto as Exhibit J, signed by a Servicing Officer, release the related portion of the Mortgage File to the Servicer, and the Indenture Trustee shall execute such documents, at the expense of and in the forms provided by the Servicer, as shall be necessary for the prosecution of any such proceedings or the taking of other servicing actions. Such Request for Release shall obligate the Servicer to return the portion of the Mortgage File released to it to the Indenture Trustee when the need therefor by the Servicer no longer exists unless the Mortgage Loan shall be liquidated, in which case, upon receipt of a certificate of a Servicing Officer similar to that hereinabove specified (including a certification that the Servicer has deposited the proceeds of such liquidated Mortgage Loan in the Collection Account), a copy of the Request for Release shall be released by the Indenture Trustee to the Servicer.

     In order to facilitate the foreclosure of the Mortgage securing any Mortgage Loan that is in default following recordation of the related Assignment of Mortgage in accordance with the provisions hereof, the Indenture Trustee shall, if so requested in writing by the Servicer execute an appropriate assignment in the form provided to the Trust and the Indenture Trustee by the Servicer to assign such Mortgage Loan for the purpose of collection to the Servicer (any such assignment shall unambiguously indicate that the assignment is for the purpose of collection only) and, upon such assignment, such assignee for collection will thereupon bring all required actions in its own name and otherwise enforce the terms of the Mortgage Loan and deposit or credit the Net Recoveries received with respect thereto in the Collection Account. In the event that all delinquent payments due under any such Mortgage Loan are paid by the Mortgagor and any other defaults are cured then the assignee for collection shall promptly reassign such Mortgage Loan to the Indenture Trustee and return it to the place where the related Mortgage File was being maintained.

     Section 3.09 Servicing Compensation; Payment of Certain Expenses by Servicer. The Servicer shall be entitled to retain the Servicing Fee in accordance with Section 3.02 as compensation for its services in connection with servicing the Mortgage Loans. Moreover, additional servicing compensation in the form of late payment charges or other receipts not considered interest or principal payments under the Mortgage Notes, Foreclosure Profits and, subject to Section 3.02(b) above (except as noted in Section 5.08(d) below), investment income on the Collection Account or the Reinvestment Account shall be retained by the Servicer. The Servicer shall be required to pay all expenses incurred by it in connection with its activities hereunder (including payment of all other fees and expenses not expressly stated hereunder to be for the account of the Trust) and shall not be entitled to reimbursement therefor except as specifically provided herein. In addition, the Servicer shall be entitled to any Prepayment Interest Excess, which it may withdraw from the Collection Account pursuant to Section 3.03(x).

     Section 3.10 Annual Statement as to Compliance.

     (a) Not later than March 1st of each calendar year (or, if such day is not a Business Day, the immediately preceding Business Day), commencing in 2005, the Servicer shall deliver to the Depositor, the Rating Agencies, the Insurer and the Indenture Trustee an Officer’s Certificate in the form of Exhibit C, stating, as to the signer thereof, that (i) a review of the activities of the Servicer during the preceding calendar year (or such shorter period in the event of the first year following the Closing Date) and of the performance of the Servicer under this Agreement has been made under such officer’s supervision, and (ii) to the best of such officer’s knowledge, based on such review, the Servicer has fulfilled all its obligations under this Agreement throughout such year, or, if there has been a material default in the fulfillment of any such obligation, specifying each such material default known to such officer and the nature and status thereof and the action being taken by the Servicer to cure such material default.

     (b) The Servicer shall deliver to the Indenture Trustee, the Insurer, the Seller, the Depositor and each of the Rating Agencies, promptly after having obtained knowledge thereof, but in no event later than five Business Days thereafter, written notice by means of an Officer’s Certificate of any event which, with the giving of notice or the lapse of time or both, would become an Event of Servicing Termination.

     Section 3.11 Annual Servicing Report.

     (a) Not later than March 1st of each calendar year (or, if such day is not a Business Day, the immediately preceding Business Day), commencing in 2006, the Servicer, at its expense, shall cause a firm of independent public accountants (who may also render other services to the Servicer or the Seller) reasonably acceptable to the Insurer to furnish a statement to the Insurer, the Depositor, the Indenture Trustee, the Trust and the Rating Agencies to the effect that such firm has examined certain documents and records relating to the servicing of the Mortgage Loans under this Sale and Servicing Agreement or of mortgage loans and sale and servicing agreements substantially the same as this Agreement (the statement to include a list of such sale and servicing agreements covered by it) and that, on the basis of its examination conducted substantially in compliance with the Audit Guide for Audits of HUD Approved Nonsupervised Mortgagees, the Uniform Single Attestation Program for Mortgage Bankers, or the Audit Program for Mortgages serviced for Fannie Mae or Freddie Mac, such servicing has been conducted in compliance with this Agreement, except for any significant exceptions or errors in records that, in the opinion of the accounting firm, the Audit Guide for Audits of HUD Approved Nonsupervised Mortgagees, the Uniform Single Attestation Program for Mortgage Bankers, or the Audit Program for Mortgages serviced by Fannie Mae and Freddie Mac requires it to report. In rendering the statement, the accounting firm may rely, as to matters relating to direct servicing of Mortgage Loans by the subservicers, upon comparable statements for examinations conducted substantially in compliance with Audit Guide for Audits of HUD Approved Nonsupervised Mortgagees, the Uniform Single Attestation Program for Mortgage Bankers, or the Audit Program for Mortgages serviced for Fannie Mae or Freddie Mac (rendered within one year of the statement) of independent public accountants with respect to the related subservicer. The certification required by this Section 3.11(a) may be replaced by any similar certification using standards other than those identified herein which are now or in the future in use by servicers of comparable assets or which otherwise comply with any rule, regulation, “no action” letter or similar guidance promulgated by the Commission, with the consent of the Insurer and the Depositor.

     (b) In the event such firm requires the Indenture Trustee or the Trust to agree to the procedures performed by such firm, the Servicer shall direct the Indenture Trustee or the Trust in writing to so agree; it being understood and agreed that the Indenture Trustee will deliver such letter of agreement in conclusive reliance upon the direction of the Servicer, and the Indenture Trustee will make no independent inquiry or investigation as to, and shall have no obligation or liability in respect of, the sufficiency, validity or correctness of such procedures.

     Section 3.12 Access to Certain Documentation and Information Regarding the Mortgage Loans. The Servicer shall provide to the Indenture Trustee, the Insurer, Class A Noteholders that are federally insured savings and loan associations, the Office of Thrift Supervision, the FDIC and the supervisory agents and examiners of the Office of Thrift Supervision access to the documentation regarding the Mortgage Loans required by applicable regulations of the Office of Thrift Supervision and the FDIC, such access being afforded without charge but only upon reasonable request and during normal business hours at the offices of the Servicer. Nothing in this Section 3.12 shall derogate from the obligation of the Servicer to observe any applicable law prohibiting disclosure of information regarding the Mortgagors and the failure of the Servicer to provide access as provided in this Section 3.12 as a result of such obligation shall not constitute a breach of this Section 3.12; provided that the Servicer makes reasonable efforts to provide such information without violation of law.

     Section 3.13 [Reserved].

     Section 3.14 Certification of the Servicer.

     (a) The Servicer, the Depositor and the Indenture Trustee shall reasonably cooperate in connection with the Trust’s satisfying the reporting requirements under the Exchange Act. The Indenture Trustee shall prepare and the Servicer shall execute on behalf of the Issuer any Forms 8-K and 10-K (together, the “Forms”) customary for similar securities as required by the Exchange Act and the rules and regulations promulgated thereunder; provided that the Depositor shall prepare, execute and file the Form 8-Ks related to the filing of the Transaction Documents and the financial statements of the Note Insurer. The Servicer hereby grants to the Indenture Trustee a limited power of attorney to execute and file each such Form 8-K but only to the extent no accompanying certification is required to be filed on behalf of the Servicer. Such power of attorney shall continue until either the earlier of (i) receipt by the Indenture Trustee from the Servicer of written termination of such power of attorney and (ii) the termination of the Trust. The Indenture Trustee shall cause to be filed (via the Commission’s Electronic Data Gathering and Retrieval System) any such Forms on behalf of the Issuer. Prior to January 31st of the first year in which such filing is permitted under applicable law, the Indenture Trustee shall prepare and file a Form 15D Suspension Notification with respect to the Trust. Each of the Seller, the Servicer and the Depositor agrees to promptly furnish to the Indenture Trustee, from time to time upon request, such further information, reports, and financial statements within its control related to this Agreement and the Mortgage Loans as the Indenture Trustee reasonably deems appropriate to prepare and file all necessary reports with the Commission.

     (b) So long as a Form 15D Suspension Notification with respect to the Trust has not previously been filed, each Form 8-K shall be filed by the Indenture Trustee within 15 days after each Payment Date, with a copy of the Statement to Class A Noteholders for such Payment Date as an exhibit thereto. Upon request by the Servicer, the Indenture Trustee will forward any Form 8-Ks to be filed by the Indenture Trustee, to the Servicer for review no later than 5 Business Days following a Distribution Date and the Servicer will provide any comments on such Form 8-Ks no later than 7 Business Days following a Distribution Date. So long as a Form 15D Suspension Notification with respect to the Issuer has not previously been filed (except with respect to the calendar year in which such Form 15D is filed), prior to March 31st of each year (or such earlier date as may be required by the Exchange Act and the rules and regulations of the Commission), the Indenture Trustee shall file a Form 10-K, in substance as required by applicable law or applicable Commission staff’s interpretations. Such Form 10-K shall include as exhibits the Servicer’s annual statement of compliance described under Section 3.10 and an annual report from the independent public accountants as to compliance by the Servicer with particular servicing standards, in each case to the extent they have been timely delivered to the Indenture Trustee. If they are not so timely delivered, the Indenture Trustee shall file an amended Form 10-K including such documents as exhibits reasonably promptly after they are delivered to the Indenture Trustee. The Indenture Trustee shall have no liability with respect to any failure to properly prepare or file such periodic reports resulting from or relating to the Indenture Trustee’s inability or failure to obtain any information not resulting from its own negligence or willful misconduct. The Form 10-K shall also include the certification in the form set forth in Section 3.14(c) below (the “Certification”), which shall be signed by the senior officer of the Servicer in charge of securitization. The Indenture Trustee shall prepare and deliver each Form 10-K to the Servicer for execution no later than March 20th (or if such day is not a Business Day, the immediately preceding Business Day) of each year. The Servicer shall return the executed Form 10-K to the Indenture Trustee for filing no later than March 25th (or if such day is not a Business Day, the immediately preceding Business Day) of each year.

     (c) On or prior to (i) March 25, 2005 and (ii) unless and until a Form 15D Suspension Notification shall have been filed, on or prior to March 1 of each year thereafter, the Servicer shall provide the Indenture Trustee with the Certification. Unless the Commission issues written guidance or otherwise informs the Seller, the Depositor, the Trust, the Indenture Trustee or the Servicer in writing that the approach set forth below is not permissible, the parties agree that the Certification included in the Trust’s Form 10-K shall be in the following form:

Certification

       I,                     , certify that

     In giving the certifications above, I have reasonably relied on information provided to me by the following unaffiliated party: Deutsche Bank National Trust Company, as Indenture Trustee.

     Notwithstanding that the Certification is to be signed by the senior officer in charge of servicing of the Servicer, a Responsible Officer of the Indenture Trustee shall sign a certification, in the form attached hereto as Exhibit I (the “Indenture Trustee Certification”), for the benefit of the Servicer and its officers, directors and Affiliates (provided, however, that the Indenture Trustee shall not undertake an analysis of the accountant’s report attached as an exhibit to the Form 10-K). The form of certification attached as Exhibit I hereto is subject to revision so as to conform to any amendments made to the Sarbanes-Oxley Act of 2002 or to any rules and regulations promulgated thereto. Each such certification shall be delivered to the Servicer, no later than March 20th of each year (or if such day is not a Business Day, the immediately preceding Business Day). In the event that prior to the filing date of the Form 10-K in March of each year, the Indenture Trustee or the Depositor has actual knowledge of information material to the Certification, that party shall promptly notify the Servicer and each of the other parties signing the certifications.

     (d) The Indenture Trustee shall have no responsibility to file any items other than those specified in this Section 3.14; provided, however, the Indenture Trustee shall cooperate (but shall not be obligated to execute except by virtue of a power of attorney and as mutually agreed) with the Servicer in connection with any additional filings with respect to the Issuer as

the Servicer deems necessary under the Exchange Act. Copies of all reports filed by the Indenture Trustee under the Exchange Act shall be sent to the Servicer and the Depositor. Fees and expenses incurred by the Indenture Trustee in connection with this Section 3.14 shall not be reimbursable from the Trust.

     (e) The Seller, the Depositor, the Servicer and the Indenture Trustee agree to use their good faith efforts to cooperate in complying with the requirements of this section.

     (f) The Servicer covenants and agrees to indemnify the Depositor and the Indenture Trustee and their officers, directors, employees and agents from, and hold them harmless against, any and all losses, liabilities, damages, claims or expenses incurred in connection with or relating to a breach of the Servicer’s obligations under this Section 3.14. If the indemnification provided for herein is unavailable or insufficient to hold harmless the Depositor and the Indenture Trustee, then the Servicer, in connection with or relating to a breach of the Servicer’s obligations under this Section 3.14, agrees that it shall contribute to the amount paid or payable by the Depositor and the Indenture Trustee as a result of the losses, liabilities, damages, claims or expenses of the Depositor and the Indenture Trustee in such proportion as is appropriate to reflect the relative fault and the relative benefit of the Servicer on the one hand and the Depositor and the Indenture Trustee on the other.

     (g) The Indenture Trustee shall indemnify and hold harmless the Servicer and the Depositor, their respective officers and directors from and against any and all losses, claims, expenses, damages or liabilities, as and when such losses, claims, expenses, damages or liabilities are incurred, insofar as such losses, claims, expenses, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement of any material fact contained in the Indenture Trustee Certification.

     Section 3.15 Reports of Foreclosures and Abandonments of Mortgaged Properties, Returns Relating to Mortgage Interest Received from Individuals and Returns Relating to Cancellation of Indebtedness. The Servicer shall, beginning in 2005, make annual reports of foreclosures and abandonments of any Mortgaged Property. The Servicer shall file or cause to be filed reports relating to each instance occurring during the previous calendar year in which the Servicer (i) on behalf of the Trust acquires an interest in any Mortgaged Property through foreclosure or other comparable conversion in full or partial satisfaction of a Mortgage Loan or (ii) knows or has reason to know that any Mortgaged Property has been abandoned. The reports shall be in form and substance sufficient to meet the reporting requirements imposed by Sections 6050J, 6050H and 6050P of the Code.

     Section 3.16 Assumption Agreements. When a Mortgaged Property has been or is about to be conveyed by the Mortgagor, the Servicer shall, to the extent it has knowledge of such conveyance or prospective conveyance, exercise its right to accelerate the maturity of the related Mortgage Loan under any “due-on-sale” clause contained in the related Mortgage or Mortgage Note; provided, however, that the Servicer shall not exercise any such right if the “due-on-sale” clause, in the reasonable belief of the Servicer, is not enforceable under applicable law. In such event, the Servicer shall enter into an assumption and modification agreement with the person to whom such property has been or is about to be conveyed, pursuant to which such person shall become liable under the Mortgage Note and, unless prohibited by applicable law, the Mortgagor

shall remain liable thereon. The Servicer, in accordance with accepted mortgage loan servicing standards for mortgage loans similar to the Mortgage Loans, is also authorized to enter into a substitution of liability whereby such person is substituted as mortgagor and becomes liable under the Mortgage Note. The Servicer shall notify the Indenture Trustee and the Insurer in writing that any such substitution or assumption agreement has been completed, and add such agreement to the related Mortgage File and shall, for all purposes, be considered a part of such Mortgage File to the same extent as all other documents and instruments constituting a part thereof. In connection with any assumption or substitution agreement entered into pursuant to this Section 3.16, the Servicer shall not change the Loan Rate or the Monthly Payment, defer or forgive the payment of principal or interest, reduce the outstanding principal amount or extend the final maturity date on such Mortgage Loan.

     Notwithstanding the foregoing paragraph or any other provision of this Agreement, the Servicer shall not be deemed to be in default, breach or any other violation of its obligations hereunder by reason of any assumption of a Mortgage Loan by operation of law or any assumption which the Servicer may be restricted by law from preventing, for any reason whatsoever.

     Section 3.17 Payment of Taxes, Insurance and Other Charges. With respect to each Mortgage Loan, the Servicer shall not be required to maintain records relating to payment of taxes.

     Section 3.18 Escrow Payments and Servicing Account. The Servicer shall, with respect to its servicing of Residential Lot Loans, establish and maintain, or cause to be established and maintained, one or more accounts (the “Servicing Accounts”), into which all Escrow Payments received by Servicer in respect of such Residential Lot Loans shall be deposited and retained. Servicing Accounts shall be Eligible Accounts. The Servicer shall deposit in the clearing account in which it customarily deposits payments and collections on residential lot loans in connection with its residential lot loan servicing activities on a daily basis, and in no event more than one business Day after Servicer’s receipt thereof, all Escrow Payments collected on account of Residential Lot Loans and shall thereafter deposit such Escrow Payments in the Servicing Accounts, in no event more than two Business Days after the receipt of such Escrow Payments, all Escrow Payments collected on account of the Residential Lot Loans for the purpose of effecting the timely payment of any such items as required under the terms of this Agreement. Withdrawals of amounts from a Servicing Account may be made only to (i) effect payment of taxes, assessments and comparable items in a manner and at a time that assures that the lien priority of the Mortgage is not jeopardized (or, with respect to the payment of taxes, in a manner and at a time that avoids the loss of the Mortgaged Property due to a tax sale or the foreclosure as a result of a tax lien); (ii) reimburse the Servicer (or a Sub-Servicer to the extent provided in the related Sub-Servicing Agreement) out of related collections for any Servicing Advances made pursuant to Section 3.01 (with respect to taxes and assessments); (iii) refund to Mortgagors any sums as may be determined to be overages; (iv) pay interest, if required and as described below, to Mortgagors on balances in the Servicing Account; (v) to pay the Servicer excess interest on funds in the Servicing Accounts to the extent permitted as provided below; or (vi) clear and terminate the Servicing Account at the termination of the Servicer’s obligations and responsibilities in respect of the Residential Lot Loans. In the event the Servicer shall deposit in a Servicing Account any amount not required to be deposited

therein, it may at any time withdraw such amount from such Servicing Account, any provision herein to the contrary notwithstanding. The Servicer will be responsible for the administration of the Servicing Accounts and will be obligated to make Servicing Advances to such accounts when and as necessary to avoid the lapse of insurance coverage on the Mortgaged Property, or which the Servicer knows, or in the exercise of the required standard of care of the Servicer hereunder should know, is necessary to avoid the loss of the Mortgaged Property due to a tax sale or the foreclosure as a result of a tax lien. If any such payment has not been made and the Servicer receives notice of a tax lien with respect to the Mortgage being imposed, the Servicer will, within 10 Business Days of such notice, advance or cause to be advanced funds necessary to discharge such lien on the Mortgaged Property. As part of its servicing duties, the Servicer or the Sub-Servicers shall pay to the Mortgagors interest on funds in the Servicing Accounts, to the extent required by law and, to the extent that interest earned on funds in the Servicing Accounts is insufficient to pay such interest from its or their own funds, without any reimbursement therefor. The Servicer may pay to itself any excess interest on funds in the Servicing Accounts, to the extent such action is in conformity with the Accepted Servicing Practices, is permitted by law and such amounts are not required to be paid to Mortgagors or used for any of the other purposes set forth above.

     Section 3.19 Remittance Reports; Advances.

     (a) Remittance Report. By each Determination Date, the Servicer shall provide to the Indenture Trustee and the Insurer in electronic form the information needed to determine the payments to be made pursuant to Section 5.01 and any other information on which the Servicer and the Indenture Trustee mutually agree. On or before the fifth Business Day following the end of each Prepayment Period (but in no event later than the third Business Day prior to the related Payment Date), the Servicer shall deliver to the Indenture Trustee and the Insurer (which delivery may be by electronic data transmission) a report in substantially the form agreed to by the Servicer and the Indenture Trustee (the “Remittance Report”). The Indenture Trustee shall not be responsible to recompute, recalculate or verify any information provided to it by the Servicer.

     (b) Advances. With respect to Residential Lot Loans, the amount of Advances to be made by the Servicer for any Payment Date shall equal, subject to Section 3.19(d), the sum of (i) the aggregate amount of Monthly Payments (net of the related Servicing Fee), due during the related Due Period in respect of the Mortgage Loans, which Monthly Payments were delinquent on a contractual basis as of the close of business on the related Determination Date and (ii) with respect to each REO Property relating to a Residential Lot Loan, which REO Property was acquired during or prior to the related Due Period and as to which REO Property and REO Disposition did not occur during the related Due Period, an amount equal to the excess, if any, of the REO Imputed Interest on such REO Property for the most recently ended calendar month, over the net income from such REO Property transferred to the Payment Account pursuant to Section 3.07 for payment on such Payment Date. On or before 3:00 p.m. New York time on the Servicer Remittance Date, the Servicer shall remit in immediately available funds to the Indenture Trustee for deposit in the Payment Account an amount equal to the aggregate amount of Advances, if any, to be made in respect of the Mortgage Loans and REO Properties for the related Payment Date either (i) from its own funds or (ii) from the Collection Account, to the extent of funds held therein for future payment (in which case it will cause to be made an

appropriate entry in the records of Collection Account that amounts held for future payment have been, as permitted by this Section 3.19, used by the Servicer in discharge of any such Advance) or (iii) in the form of any combination of (i) and (ii) aggregating the total amount of Advances to be made by the Servicer with respect to the Mortgage Loans and REO Properties. Any amounts held for future payment used by the Servicer to make an Advance as permitted in the preceding sentence shall be appropriately reflected in the Servicer’s records and replaced by the Servicer by deposit in the Collection Account on or before any future Servicer Remittance Date to the extent that the Available Funds for the related Payment Date (determined without regard to Advances to be made on the Servicer Remittance Date) shall be less than the total amount that would be paid to the Class A Noteholders pursuant to Section 5.01 on such Payment Date if such amounts held for future payments had not been so used to make Advances. The Indenture Trustee will provide notice to the Servicer by telecopy by the close of business on any Servicer Remittance Date in the event that the amount remitted by the Servicer to the Indenture Trustee on such date is less than the Advances required to be made by the Servicer for the related Payment Date, as set forth in the related Remittance Report.

     (c) The obligation of the Servicer to make such Advances is mandatory, notwithstanding any other provision of this Agreement but subject to (d) below, and, with respect to any Mortgage Loan, shall continue until a Final Recovery Determination in connection therewith or the removal thereof from the Trust Fund pursuant to any applicable provisions of this Agreement, except as otherwise provided in this Section.

     (d) Notwithstanding anything herein to the contrary, no Advance or Servicing Advance shall be required to be made hereunder by the Servicer if such Advance or Servicing Advance would, if made, constitute a Nonrecoverable Advance. The determination by the Servicer that it has made a Nonrecoverable Advance or that any proposed Advance or Servicing Advance, if made, would constitute a Nonrecoverable Advance, shall be evidenced by an Officer’s Certificate of the Servicer delivered to the Depositor, the Indenture Trustee and the Insurer.

     Section 3.20 Obligations of the Servicer in Respect of Prepayment Interest Shortfalls.

     Not later than 3:00 p.m. New York time on each Servicer Remittance Date, the Servicer shall remit from its own funds to the Payment Account an amount (“Compensating Interest”) equal to the lesser of (A) the aggregate of the Prepayment Interest Shortfalls for the related Payment Date and (B) one-half of its aggregate Servicing Fee received in the related Due Period and any Prepayment Interest Excess collected by the Servicer during the related Prepayment Period. The Servicer shall not have the right to reimbursement for any amounts remitted to the Trustee in respect of Compensating Interest. Such amounts so remitted shall be included in the Interest Collections and distributed therewith on the next Payment Date. The Servicer shall not be obligated to pay any compensating amounts with respect to Relief Act Interest Shortfalls.

     Section 3.21 Allocation of Realized Losses.

     (a) For each Payment Date, the Servicer shall calculate the amount of Realized Losses on the Mortgage Loans that occurred during the preceding Prepayment Period, and shall include such calculation in its Remittance Report.

     (b) All Realized Losses on the Mortgage Loans allocated to any of the Class B Certificates and the Class O Certificates shall be allocated by the Indenture Trustee on each Payment Date as follows: first, to the Class O Certificates, to the extent of any amount distributable to the Class O Certificates pursuant to Section 5.01(a)I.(xvii), second, to the Class O Principal Distribution Amount, third, to the Class B-2 Interest Distribution Amount, fourth, to the Class B-1 Interest Distribution Amount, fifth, to the Class O Certificates, until the Class O Certificate Principal Balance has been reduced to zero, sixth, to the Class B-2 Principal Distribution Amount and seventh, to the Class B-1 Principal Distribution Amount.

ARTICLE IV.

INSURER

     Section 4.01 Claims upon the Note Policy.

     (a) As soon as possible, and in no event later than 12:00 noon New York City time on the second Business Day immediately preceding the Payment Date, the Indenture Trustee shall furnish the Insurer and the Servicer with a completed notice in the form set forth as Exhibit A to the Note Policy (the “Notice for Payment”) in the event that the Insured Amount for such Payment Date is an amount greater than zero. The Notice for Payment shall specify the amount of the Insured Amount and shall constitute a claim for an Insured Amount pursuant to the Note Policy. Upon receipt of an Insured Amount on behalf of the Holders of the Class A Notes under the Note Policy, the Indenture Trustee shall deposit such Insured Amount in the Payment Account and shall distribute such Insured Amount pursuant to Section 5.01 (a)I(iv) or II(ii), as the case may be (provided that any amount paid under clause (a) of the definition of “Class A Principal Distribution Amount” in the Note Policy shall be paid to the Class A Noteholders as a payment of principal).

     (b) The Indenture Trustee shall keep a complete and accurate record of the amount of interest and principal paid from moneys received under the Note Policy. The Insurer shall have the right to inspect such records at reasonable times during normal business hours of the Indenture Trustee upon four Business Days’ prior written notice to the Indenture Trustee.

     (c) If a payment to the Class A Noteholders which is guaranteed pursuant to the Note Policy is voided (a “Preference Event”) under any applicable bankruptcy, insolvency, receivership or similar law in an insolvency proceeding (as such term is used in the Note Policy), and, as a result of such a Preference Event, the Indenture Trustee is required to return such voided payment, or any portion of such voided payment, made in respect of the Class A Notes (an “Preference Amount”), the Indenture Trustee shall furnish to the Insurer (i) a certified copy of a final non-appealable order of a court or other body exercising jurisdiction in such insolvency proceeding to the effect that the Indenture Trustee, or Holder, as applicable, is required to return any such payment or portion thereof during the term of the Note Policy because such payment was voided as a preferential transfer or otherwise rescinded or required to be restored by the Indenture Trustee or Holder (the “Final Order”), (ii) an Opinion of Counsel satisfactory to the Insurer that such order is final and not subject to any stay, (iii) an assignment, in form and substance satisfactory to the Insurer, duly executed and delivered by the Indenture Trustee or Holder, irrevocably assigning to the Insurer all rights and claims of the Indenture Trustee and/or such Holder relating to or arising under this Agreement against the estate of the Indenture Trustee or otherwise with respect to such Preference Amount, (iv) appropriate instruments in form satisfactory to the Insurer to effect the appointment of the Insurer as agent for the Indenture Trustee and such Holder in any legal proceeding relating to such Preference Amount and (v) a Notice for Payment appropriately completed and executed by the Indenture Trustee. Such payment shall be disbursed to the receiver, conservator, debtor-in-possession or trustee in bankruptcy named in the Final Order and not to the Indenture Trustee directly (unless a Class A Noteholder has previously paid such amount to the receiver, conservator, debtor-in-possession or trustee in bankruptcy named in the Final Order in which case such payment shall be disbursed to

the Indenture Trustee for payment to such Class A Noteholder upon delivery of (a) the items referred to in clauses (i), (ii), (iii), (iv) and (v) above and (b) evidence satisfactory to the Insurer that payment has been made to such court or receiver, conservator, debtor-in-possession or trustee in bankruptcy named in the Final Order). The Indenture Trustee is not permitted to make a claim on the Trust or on any Class A Noteholder for payments made to any Class A Noteholder which are characterized as preference payments by any bankruptcy court having jurisdiction over any bankrupt Mortgagor unless ordered to do so by such bankruptcy court.

     (d) Any amounts received by the Indenture Trustee pursuant to the Note Policy in respect of the Class A Notes shall be deposited to the Payment Account.

     Section 4.02 Effect of Payments by the Insurer; Subrogation. Anything herein to the contrary notwithstanding, any payment with respect to principal of or interest on any of the Class A Notes which are made with moneys received pursuant to the terms of the Note Policy shall not be considered payment of such Class A Notes, as applicable, from the Trust and shall not result in the payment of or the provision for the payment of the principal of or interest on such Class A Notes, as applicable, within the meaning of Section 5.01 herein. The Seller, the Depositor, the Servicer and the Indenture Trustee acknowledge, and each Holder by its acceptance of a Class A Note agrees, that without the need for any further action on the part of the Insurer, the Seller, the Depositor, the Servicer, the Indenture Trustee or the Certificate Registrar (a) to the extent the Insurer makes payments, directly or indirectly, on account of principal of or interest on any Class A Notes to the Holders of such Class A Notes, the Insurer will be fully subrogated to the rights of such Holders to receive such principal and interest, as applicable, from the Trust and (b) the Insurer shall be paid such principal and interest but only from the sources and in the manner provided herein and in the Insurance Agreement for the payment of such principal and interest.

     The Indenture Trustee and the Servicer shall cooperate in all respects with any reasonable request by the Insurer for action to preserve or enforce the Insurer’s rights or interests under this Agreement without limiting the rights or affecting the interests of the Holders of the Class A Notes as otherwise set forth herein.

     Section 4.03 Replacement Note Policy. In the event of a default by the Insurer under the Note Policy or if the financial strength of the Insurer, within the two-year period commencing on the Closing Date, is not rated at least “AA-” by Standard & Poor’s and “Aa3” by Moody’s (in each case, a “Replacement Event”), the Seller may, in accordance with and upon satisfaction of the conditions set forth in the Note Policy and the Insurance and Indemnity Agreement, the payment in full of all amounts owed to the Insurer, and the receipt of a statement in writing from each Rating Agency stating that the substitution referred to below would not result in the downgrading or withdrawal of the respective ratings then assigned to the Class A Notes (without regard to the Note Policy), but shall not be required to, substitute a new insurance policy or insurance policies for the existing Note Policy, or may arrange for any other form of credit enhancement; provided, however, that in each case the Class A Notes shall be rated no lower than the rating assigned by each Rating Agency to the Class A Notes immediately prior to such Replacement Event. It shall be a condition to substitution of any new credit enhancement that there be delivered to the Indenture Trustee (i) a legal opinion, acceptable in form and substance to the Indenture Trustee, from counsel to the provider of such new credit enhancement with respect to the enforceability thereof and such other matters as the Indenture Trustee may require and (ii) an Opinion of Counsel to the effect that such substitution would not have a materially adverse tax effect on the Class A Noteholders or the Trust. Upon receipt of the items referred to above and the taking of physical possession of the new credit enhancement, the Indenture Trustee shall, within five Business Days following receipt of such items and such taking of physical possession, deliver the replaced Note Policy to the Insurer.

     (b) Distributions on the Transferor Interest. On each Payment Date, the Indenture Trustee shall pay the following amounts, from Transferor Interest Collections, in the following order of priority:

     Amounts of principal shall be distributed to the Transferor in accordance with Section 5.01(a)(II)(vi) above.

     In the event that any withholding tax is imposed on the Trust’s payment (or allocations of income) to the Transferor under this Section 5.01(a), such tax shall reduce the amount otherwise distributable to the Transferor. The Indenture Trustee is hereby authorized and directed to retain from amounts otherwise distributable to the Transferor sufficient funds for the payment of any tax that is legally owed by the Trust (but such authorization shall not prevent the Indenture Trustee from contesting any such tax in appropriate proceedings, and withholding payment of such tax, if permitted by law, pending the outcome of such proceedings). The amount of any

withholding tax imposed with respect to the Transferor shall be treated as cash distributed to the Transferor at the time it is withheld by the Trust and remitted to the appropriate taxing authority. If there is a possibility that withholding tax is payable with respect to a payment (such as a payment to a non-U.S. person), the Indenture Trustee may in its sole discretion withhold such amounts in accordance with this paragraph. In the event that the Transferor wishes to apply for a refund of any such withholding tax, the Indenture Trustee shall reasonably cooperate with the Transferor in making such claim so long as the Transferor agrees to reimburse the Indenture Trustee for any out-of-pocket expenses incurred.

     (c) Method of Distribution. The Indenture Trustee shall make payments and distributions in respect of a Payment Date to the Class A Noteholders and the Certificateholders of record on the related Record Date (other than as provided in Section 8.01 respecting the final payment) by check or money order mailed to such Class A Noteholders and Certificateholders at the address appearing in the Note Register and the Certificate Register, respectively, or upon written request by a Class A Noteholder or Certificateholder, as applicable, delivered to the Indenture Trustee at least five Business Days prior to such Record Date, by wire transfer, or by such other means of payment as such Class A Noteholder or Certificateholder and the Indenture Trustee shall agree. Distributions among Class A Noteholders and the Certificateholders shall be made in proportion to the Percentage Interests evidenced by the Class A Notes held by such Class A Noteholder and the Percentage Interests evidenced by the Certificates held by such Certificateholders.

     (d) Payments on Book-Entry Notes. Each payment with respect to a Book-Entry Note shall be paid to the Depository, which shall credit the amount of such payment to the accounts of its Depository Participants in accordance with its normal procedures. Each Depository Participant shall be responsible for disbursing such payment to the Class A Notes that it represents and to each indirect participating brokerage firm (a “brokerage firm” or “indirect participating firm”) for which it acts as agent. Each brokerage firm shall be responsible for disbursing funds to the Class A Note Owners that it represents. All such credits and disbursements with respect to a Book-Entry Note are to be made by the Depository and the Depository Participants in accordance with the provisions of the Class A Notes. None of the Indenture Trustee, the Note Registrar, the Seller, the Insurer, the Trust or the Servicer shall have any responsibility therefor except as otherwise provided by applicable law.

     (e) [Reserved.]

     (f) Allocation of Investor Charge-Off Amounts. On each Payment Date, the Indenture Trustee shall determine the total of the Investor Charge-Off Amounts for such Payment Date. The Investor Charge-Off Amounts for any Payment Date shall be applied by reducing first, to the Class O Certificates, to the extent of any amount distributable to the Class O Certificates pursuant to Section 5.01(a)I.(xvii), second, to the Class O Principal Distribution Amount, third, to the Class B-2 Interest Distribution Amount, fourth, to the Class B-1 Interest Distribution Amount, fifth, to the Class O Certificates, until the Class O Certificate Principal Balance has been reduced to zero, sixth, to the Class B-2 Principal Distribution Amount and seventh, to the Class B-1 Principal Distribution Amount. Any Investor Charge-Off Amount allocated to a Class of Certificates shall be allocated among such Certificates of such Class in proportion to their respective Percentage Interests.

     With respect to any Class of Certificates to which an Investor Charge-Off Amount has been allocated (including any such Class for which the related Certificate Principal Balance has been reduced to zero), the Certificate Principal Balance of such Class will be increased up to the amount of related Recoveries for such Payment Date, first to the Class B-1 Certificates, and second, to the Class B-2 Certificates, and third, to the Class O Certificates, up to the amount of Investor Charge-Off Amounts previously allocated to reduce such Certificate Principal Balance. Any increase to the Certificate Principal Balance of a Class B Certificate or a Class O Certificate shall increase the aggregate Certificate Principal Balance of the related Class pro rata in accordance with the related Percentage Interest of each such Class.

     Section 5.02 Calculation of the Class A Note Rate and Class B Certificate Rate. With respect to the Class A Notes and the Class B Certificates, on the second LIBOR Business Day immediately preceding each Payment Date (or as of the second LIBOR Business Day prior to the Closing Date, in the case of the first Payment Date), the Indenture Trustee shall determine LIBOR for the Interest Period commencing on such Payment Date and inform the Servicer (at the facsimile number given to the Indenture Trustee in writing) of such rates. On or prior to each Payment Date, the Indenture Trustee shall determine the applicable Class A Note Rate and Class B Certificate Rate for the related Payment Date.

In the event that the Trust is required to file tax returns, the Owner Trustee, on behalf of the Trust, shall elect under Section 1278 of the

Code to include in income currently any market discount that accrues with respect to the Mortgage Loans. The Owner Trustee, on behalf of the Trust, shall prepare or shall cause to be prepared any tax returns required to be filed by the Trust and shall remit such returns to the Transferor at least five days before such returns are due to be filed. The Owner Trustee or such party required by law, shall promptly sign such returns and deliver such returns after signature to the Owner Trustee and such returns shall be filed by, or at the direction of, the Owner Trustee with the appropriate tax authorities.

     (e) Reports and computer tapes furnished by the Servicer pursuant to this Agreement shall be deemed confidential and of a proprietary nature, and shall not be copied or distributed except to the extent provided in this Agreement and to the extent required by law or to the Rating Agencies, the Depositor, the Insurer’s attorneys, reinsurers, parent, regulators, liquidity providers and auditors and to the extent the Servicer instructs the Indenture Trustee in writing to furnish information regarding the Trust or the Mortgage Loans to third-party information providers; notwithstanding anything herein to the contrary, the foregoing shall not be construed to prohibit (i) disclosure of any and all information that is or becomes publicly known, or information obtained by Indenture Trustee from sources other than the other parties hereto, (ii) disclosure of any and all information (A) if required to do so by any applicable law, rule or regulation, (B) to any government agency or regulatory body having or claiming authority to regulate or oversee any respects of Indenture Trustee’s business or that of its affiliates, (C) pursuant to any subpoena, civil investigative demand or similar demand or request of any court, regulatory authority, arbitrator or arbitration to which Indenture Trustee or any affiliate or an officer, director, employer or shareholder thereof is a party or (D) to any affiliate, independent or internal auditor, agent, employee or attorney of Indenture Trustee having a need to know the same, provided that the Indenture Trustee advises such recipient of the confidential nature of the information being disclosed or (iii) any other disclosure authorized by the Transaction Documents, the Depositor, the Seller or the Servicer. No Person entitled to receive copies of such reports or tapes or lists of Class A Noteholders shall use the information therein for the purpose of soliciting the customers of the Seller or for any other purpose except as set forth in this Agreement.

The Reinvestment Account shall be an Eligible Account. The Indenture Trustee shall deposit any amounts representing the Reinvestment Amounts in respect of payments made pursuant to Section 5.01 (a)I(v), (vi) and (viii) in the Reinvestment Account.

     Section 6.04     Servicer Not to Resign.     Subject to the provisions of Section 6.02 above, the Servicer shall not resign from the obligations and duties hereby imposed on it except (i) upon determination that the performance of its obligations or 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 or its subsidiaries or Affiliates, the other activities of the Servicer so causing such a conflict being of a type and nature carried on by the Servicer or its subsidiaries or Affiliates at the date of this Agreement or (ii) upon satisfaction of the following conditions: (a) the Servicer has proposed a successor servicer in writing and such proposed successor servicer is reasonably acceptable to the Indenture Trustee; (b) each Rating Agency shall have delivered a letter to the Indenture Trustee prior to the appointment of the successor servicer stating that the proposed appointment of such successor servicer as Servicer hereunder will not result in the reduction or withdrawal of the then current rating of the Class A Notes without regard to the Note Policy; and (c) such proposed successor servicer is reasonably acceptable to the Insurer, as evidenced by a letter to the Indenture Trustee; provided, however, that no such resignation by the Servicer shall become effective until such successor servicer or, in the case of (i) above, the Indenture Trustee shall have assumed the Servicer’s responsibilities and obligations hereunder or the Indenture Trustee shall have designated a successor servicer in accordance with Section 7.02 below. Any such resignation shall not relieve the Servicer of responsibility for any of the obligations specified in Sections 7.01 and 7.02 below as obligations that survive the resignation or termination of the Servicer. Any such determination permitting the resignation of the Servicer pursuant to clause (i) above shall be evidenced by an Opinion of Counsel to such effect delivered to the Indenture Trustee and the Insurer.

     Section 6.05     Delegation of Duties.     In the ordinary course of business, the Servicer at any time may delegate any of its duties hereunder to any Person, including any of its Affiliates, who agrees to conduct such duties in accordance with standards comparable to those set forth in Section 3.01 herein. Such delegation shall not relieve the Servicer of its liabilities and responsibilities with respect to such duties and shall not constitute a resignation within the meaning of Section 6.04 above. The Servicer shall provide the Insurer and the Indenture Trustee with written notice prior to the delegation of any of its duties to any Person other than any of the Servicer’s Affiliates or their respective successors and assigns (provided that the Servicer may retain agents and contractors in accordance with Acceptable Servicing Practices), and the Insurer

shall have consented to the appointment of any Subservicer to the extent required by Section 3.01 hereof.

     Section 6.06     Indemnification of the Trust by the Servicer.     The Servicer shall indemnify and hold harmless the Trust and the Indenture Trustee and its officers, directors, agents and employees from and against any loss, liability, expense, damage or injury suffered or sustained by reason of the Servicer’s willful misfeasance, bad faith or gross negligence in the performance of its activities in servicing or administering the Mortgage Loans pursuant to this Agreement, including, but not limited to, any judgment, award, settlement, reasonable fees of, counsel of its selection and other costs or expenses incurred in connection with the defense of any actual or threatened action, proceeding or claim related to the Servicer’s misfeasance, bad faith or gross negligence. Any such indemnification shall not be payable from the assets of the Trust. The provisions of this indemnity shall run directly to and be enforceable by an injured party subject to the limitations hereof. The provisions of this Section 6.06 shall survive termination of the Agreement or the earlier of the resignation or removal of the Indenture Trustee.

ARTICLE VII.

SERVICING TERMINATION

          Section 7.01     Events of Servicing Termination.

If any one of the following events (each, an “Events of Servicing Termination”) shall occur and be continuing:

          (i)     any failure by the Servicer to deposit in the Collection Account, the Reinvestment Account, the Payment Account or the Revolving Period Funding Account any deposit required to be made under the terms of this Agreement, which failure continues unremedied for two Business Days after the giving of written notice of any such failure to the Servicer by a Responsible Officer of the Indenture Trustee with actual knowledge thereof, or to the Servicer and the Indenture Trustee by the Insurer or the Holders of the Senior Class of Class A Notes or Certificates, as applicable, representing not less than 25% of the aggregate Class A Note Principal Balance or the Certificate Principal Balance of such Senior Class;

          (ii)     the failure by the Servicer to make any required Servicing Advance, or, except as otherwise described in subclause (vi) below, the failure by the Servicer duly to observe or perform, in any material respect, any other covenants, obligations or agreements of the Servicer as set forth in this Agreement, in each case which failure materially and adversely affects the interests of the Class A Noteholders or the Insurer and continues unremedied for a period of 30 days, after the date on which written notice of such failure, requiring the same to be remedied, shall have been given to the Servicer by the Indenture Trustee or to the Servicer and the Indenture Trustee by the Insurer or by the Holders of the Senior Class of Class A Notes or Certificates, as applicable, representing not less than 25% of the aggregate Class A Note Principal Balance or the Certificate Principal Balance of such Senior Class;

          (iii)     the entry against the Servicer of a decree or order by a court or agency or supervisory authority having jurisdiction in the premises for the appointment of a trustee, conservator, receiver or liquidator in any insolvency, conservatorship, receivership, readjustment of debt, marshalling of assets and liabilities or similar proceedings, or for the winding up or liquidation of its affairs, and the continuance of any such decree or order unstayed and in effect for a period of 60 consecutive days; or

          (iv)     the Servicer shall voluntarily go into liquidation, consent to the appointment of a conservator or receiver or liquidator or similar person in any insolvency, readjustment of debt, marshalling of assets and liabilities or similar proceedings of or relating to the Servicer or of or relating to all or substantially all of its property, or a decree or order of a court or agency or supervisory authority having jurisdiction in the premises for the appointment of a conservator, receiver, liquidator or similar person in any insolvency, readjustment of debt, marshalling of assets and liabilities or similar proceedings, or for the winding-up or liquidation of its affairs, shall have been entered against the Servicer and such decree or order shall have remained in

Notes representing not less than 51% of the Class A Note Principal Balance (with the consent of the Insurer, so long as no Insurer Default exists), by notice then given in writing to the Servicer (and to the Indenture Trustee if given by Holders of Class A Notes), terminate all of the rights and obligations of the Servicer as servicer under this Agreement. Any such notice to the Servicer shall also be given to each Rating Agency, the Depositor, the Trust, the Insurer and the Class A Noteholders. On or after the receipt by the Servicer of such written notice, all authority and power of the Servicer under this Agreement, whether with respect to the Class A Notes or the Mortgage Loans or otherwise, shall pass to and be vested in the Indenture Trustee pursuant to and under this Section 7.01; and, without limitation, the Indenture Trustee 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 of each Mortgage Loan and related documents or otherwise. The Servicer agrees to cooperate with the Indenture Trustee in effecting the termination of the responsibilities and rights of the Servicer hereunder, including, without limitation, the transfer to the Indenture Trustee for the administration by it of all cash amounts that shall at the time be held by the Servicer and to be deposited by it in the Collection Account, or that have been deposited by the Servicer in the Collection Account or thereafter received by the Servicer with respect to the Mortgage Loans. All reasonable costs and expenses (including attorneys’ fees and expenses) incurred in connection with transferring the Mortgage Files to the successor Servicer and amending this Agreement to reflect such succession as Servicer pursuant to this Section 7.01 shall be paid by the predecessor Servicer (or if the predecessor Servicer is the Indenture Trustee, the initial Servicer) upon presentation of reasonable documentation of such costs and expenses.

     Notwithstanding any termination of the Servicer hereunder, the Servicer shall be entitled to receive, on a first in-first out basis, out of any late collection of a Monthly Payment on a Mortgage Loan that was due prior to the notice terminating the Servicer’s rights and obligations as the Servicer hereunder and received after such notice, that portion of the Servicing Fee thereof or any unreimbursed Servicing Advance made by the terminated Servicer relating to such Mortgage Loan.

     In addition, upon the occurrence of any Trigger Event, as provided in the Insurance and Indemnity Agreement, and upon the direction of the Insurer in connection therewith, the Indenture Trustee shall terminate the rights and responsibilities of the Servicer hereunder and shall appoint a successor Servicer in accordance with the provisions of Section 7.02.

     Section 7.02     Indenture Trustee to Act; Appointment of Successor.

     (a)     On and after the time the Servicer receives a notice of termination pursuant to Section 7.01 or resigns pursuant to 6.04 herein, the Indenture Trustee or a previously agreed upon successor Servicer shall be the successor in all respects to the Servicer in its capacity as servicer under this Agreement and the transactions set forth or provided for herein and shall be subject to all the responsibilities, duties and liabilities relating thereto placed on the Servicer by the terms and provisions hereof. As compensation therefor, the Indenture Trustee shall be entitled to such compensation as the Servicer would have been entitled to hereunder if no such notice of termination had been given. Notwithstanding the above, (i) if the Indenture Trustee is

unwilling to act as successor Servicer, or (ii) if the Indenture Trustee is legally unable so to act, the Indenture Trustee shall appoint or petition a court of competent jurisdiction to appoint, or the Insurer can direct the Indenture Trustee to appoint or petition a court of competent jurisdiction for the appointment of, any established housing and home finance institution, bank or other mortgage loan or home equity loan servicer having a net worth of not less than $50,000,000 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; provided that any such successor Servicer shall be acceptable to the Insurer, as evidenced by the Insurer’s prior written consent (which consent shall not be unreasonably withheld); and provided, further, that the appointment of any such successor Servicer will not result in the qualification, reduction or withdrawal of the ratings assigned to the Class A Notes by the Rating Agencies. Pending appointment of a successor to the Servicer hereunder, unless the Indenture Trustee is prohibited by law from so acting, the Indenture Trustee shall act in such capacity as hereinabove provided. Notwithstanding anything herein to the contrary, in no event shall the Indenture Trustee be held liable for any Servicing Fee or for any differential in the amount necessary to induce any successor servicer to act as successor servicer under this Agreement and the transactions set forth or provided for therein. In connection with such appointment and assumption, the successor shall be entitled to receive compensation out of payments on Mortgage Loans in an amount equal to the compensation which the Servicer would otherwise have received pursuant to Section 3.09 herein (or such lesser compensation as the Indenture Trustee and such successor may agree). The appointment of a successor Servicer shall not affect any liability of the predecessor Servicer which may have arisen under this Agreement prior to its termination as Servicer to pay any deductible under any insurance policy obtained and maintained pursuant to Section 3.05 herein or to indemnify the Trust and the Indenture Trustee pursuant to Section 6.06), nor shall any successor Servicer be liable for any acts or omissions of the predecessor Servicer or for any breach by such Servicer of any of its representations or warranties contained herein or in any related document or agreement. The Indenture Trustee and such successor shall take such action, consistent with this Agreement, as shall be necessary to effectuate any such succession.

     (b)     Any successor, including the Indenture Trustee, to the Servicer as servicer shall during the term of its service as servicer (i) continue to service and administer the Mortgage Loans for the benefit of the Trust, and (ii) maintain in force an insurance policy or policies of insurance covering errors and omissions in the performance of its obligations as Servicer hereunder and a fidelity bond in respect of its officers, employees and agents to the same extent as the Servicer maintained as of the date hereof, as the same may have been increased from time to time. No successor servicer shall have the right to retain and commingle payments on, and collections in respect of, the Mortgage Loans with its own funds pursuant to Section 3.02(d) unless (i) consented to in writing by the Insurer and (ii) such commingling will not result in a downgrade, qualification or withdrawal of the then current ratings of the Class A Notes, without regard to the Note Policy, as evidenced in writing by each Rating Agency.

     Section 7.03     Waiver of Defaults.     While the Class A Notes are outstanding, the Insurer or the Majority Holders with the consent of the Insurer (which consent shall not be unreasonably withheld) may by written notice to the Indenture Trustee, on behalf of such Class A Noteholders, waive any events permitting removal of the Servicer as servicer pursuant to this Article VII, provided, however, that the Insurer and the Majority Holders may not waive a default in making

a required payment on a Class A Note without the consent of 100% of the Holders of such Class A Notes. Upon any waiver of a past default, such default shall cease to exist and any Event of Servicing Termination arising therefrom shall be deemed to have been remedied for every purpose of this Agreement. No such waiver shall extend to any subsequent or other default or impair any right consequent thereto except to the extent expressly so waived. Notice of any such waiver shall be given by the Indenture Trustee to the Rating Agencies.

     Once the Class A Notes are no longer outstanding, the Majority Holders may by written notice to the Indenture Trustee, on behalf of all Noteholders of such Class, waive any events permitting removal of the Servicer as servicer pursuant to this Article VII. Upon any waiver of a past default, such default shall cease to exist and any Event of Servicing Termination arising therefrom shall be deemed to have been remedied for every purpose of this Agreement. No such waiver shall extend to any subsequent or other default or impair any right consequent thereto except to the extent expressly so waived. Notice of any such waiver shall be given by the Indenture Trustee to the Rating Agencies.

     Section 7.04     Notification to Class A Noteholders.     Upon any termination or appointment of a successor to the Servicer pursuant to this Article VII or Section 6.04 above, the Indenture Trustee shall give prompt written notice thereof to the Class A Noteholders at their respective addresses appearing in the Note Register, the Insurer and each Rating Agency.

ARTICLE VIII.

TERMINATION

     Section 8.01     Termination.

     (a)     The respective obligations and responsibilities of the Seller, the Servicer, the Depositor and the Indenture Trustee created hereby (other than the obligation of the Indenture Trustee to make certain payments to Class A Noteholders and distributions to the Certificateholders after the Final Payment Date, the indemnity obligations of the Servicer and the obligation of the Servicer to send certain notices as hereinafter set forth) shall terminate upon notice to the Indenture Trustee of the later of (A) payment in full of all amounts owing to the Insurer unless the Insurer shall otherwise consent and (B) the earliest of (i) the final payment or other liquidation of the last Mortgage Loan remaining in the Trust; (ii) the optional purchase by the Servicer of the Mortgage Loans as described below and (iii) the Final Payment Date.

     (b)     The Servicer may, at its option, terminate this Agreement, with the consent of the Insurer if such termination will cause a draw on the Note Policy, on or after the Payment Date on which the Class A Note Principal Balance is less than or equal to 10% of the Original Class A Note Principal Balance by purchasing, on the next succeeding Payment Date, all of the outstanding Mortgage Loans and REO Properties at a price equal to the lesser of (i) the sum of the outstanding Pool Principal Balance, accrued and unpaid interest and thereon at the weighted average of the Loan Rates through the end of the Due Period preceding the Final Payment Date and any LIBOR Interest Carry Over Amount that remains unpaid, together with all amounts due and owing to the Insurer (the “Termination Price”) and (ii) the fair market value of the Mortgage Loans; provided that the amount paid must be sufficient (x) to pay the Termination Price and (y) to pay all amounts due on the Class A Notes (including all accrued and unpaid Class A Interest Payment Amounts, any unpaid LIBOR Interest Carryover Shortfalls, and their full Class A Note Principal Balance), and all amounts owed to the Insurer and payment of all amounts due on the Class B Certificates (including all accrued and unpaid Class B Interest Distribution Amounts and their full Class B Certificate Principal Balance).

     In connection with any such purchase pursuant to the preceding paragraph, the Servicer shall deposit in the Payment Account all amounts then on deposit in the Collection Account (less amounts permitted to be withdrawn by the Servicer pursuant to Section 3.03), which deposit shall be deemed to have occurred immediately preceding such purchase.

     Any such purchase shall be accomplished by deposit into the Payment Account on the Determination Date before such Payment Date of the Termination Price.

     (c)     Notice of any termination, specifying the Payment Date (which shall be a date that would otherwise be a Payment Date) upon which the Class A Noteholders may surrender their Class A Notes to the Indenture Trustee for payment of the final payment and cancellation, shall be given promptly by the Indenture Trustee (upon receipt of written directions from the Servicer, if the Servicer is exercising its right to purchase the Mortgage Loans, given not later than the first day of the month preceding the month of such final payment) to the Insurer and to the Servicer by letter to such parties not earlier than the 15th day and not later than the 28th day

of the month next preceding the month of such final payment specifying (i) the Payment Date upon which final payment on the Class A Notes will be made upon presentation and surrender of the Class A Notes at the office or agency of the Indenture Trustee therein designated, (ii) the amount of any such final payment and (iii) that the Record Date otherwise applicable to such Payment Date is not applicable, payments being made only upon presentation and surrender of the Class A Notes at the office or agency of the Indenture Trustee therein specified.

     (d)     Upon presentation and surrender of the Class A Notes and the Certificates, the Indenture Trustee shall cause to be paid to the Holders of the Class A Notes and the Certificates on the Payment Date for such final payment, in proportion to the Percentage Interests and to the extent that funds are available for such purpose, an amount equal to the amount required to be paid to the Class A Noteholders and the Certificateholders in the order of priority specified in and otherwise pursuant to Section 5.01 for such Payment Date. The Indenture Trustee shall cause to be distributed to the Transferor amounts, if any, pursuant to Section 5.01 and Section 5.12(d). On the final Payment Date prior to having made the payments called for above, the Indenture Trustee shall, based upon the information set forth in the Servicing Certificate and the Statement to Class A Noteholders for such Payment Date, withdraw from the Payment Account and remit to the Insurer the lesser of (x) the amount available for payment on such final Payment Date, net of any portion thereof necessary to pay the Class A Noteholders pursuant to Section 5.01(a) and any amounts owing to the Indenture Trustee in respect of the Indenture Trustee Fee and (y) the unpaid amounts due and owing to the Insurer pursuant to the Insurance Agreement.

     (e)     In the event that all of the Class A Noteholders and the Certificateholders shall not surrender their Class A Notes or Certificates for final payment and cancellation on or before such final Payment Date, the Indenture Trustee shall promptly following such date cause all funds in the Payment Account not paid or distributed in final payment to such Class A Noteholder or Certificateholders to be withdrawn therefrom and credited to the remaining Class A Noteholders or Certificateholders by depositing such funds in a separate non-interest bearing trust account (which funds shall be held uninvested) for the benefit of such Class A Noteholders or Certificateholders and the Servicer (if the Servicer has exercised its right to purchase the Mortgage Loans) or the Indenture Trustee (in any other case) shall give a second written notice to the remaining Class A Noteholders or Certificateholders to surrender their Class A Notes or Certificates for cancellation and receive the final payment with respect thereto. If within nine months after the second notice all the Class A Notes and the Certificates shall not have been surrendered for cancellation, the Transferor will be entitled to all unclaimed funds and other assets which remain subject hereto and the Indenture Trustee shall transfer such funds to the Transferor and the Class A Noteholders and the Certificateholders shall thereafter look to the Transferor for payment.

     In the event that the Transferor shall not have submitted the Transferor Certificate for cancellation within six months after the date specified in the written notice, the Indenture Trustee shall give a second written notice to the Transferor with respect thereto. If within one year after such second notice, the Indenture Trustee may take appropriate steps, or may appoint an agent to take appropriate steps, to contact the Transferor concerning the final payment, and the cost thereof shall be paid out of the funds and other assets that shall remain subject to this Agreement.

     (f)     Upon payment of all amounts owed under the Note Policy and cancellation of the Class A Notes, the Indenture Trustee shall provide the Insurer notice of cancellation of the Class A Notes and surrender the Note Policy to the Insurer.

MISCELLANEOUS PROVISIONS

Section 11.01     Amendment

     (a)     This Agreement may be amended from time to time by the Seller, the Depositor, the Servicer and the Indenture Trustee by written agreement, without the consent of any of the Class A Noteholders, but only with the consent of the Insurer to the extent that Class A Notes are outstanding or any amounts are owed to the Insurer that have not been paid (which consent shall not be unreasonably withheld) while the Class A Notes are outstanding (i) to cure any ambiguity, (ii) to correct any defective provisions or to correct or supplement any provisions herein that may be inconsistent with any other provisions herein, (iii) to add to the duties of the Servicer, (iv) to add any other provisions with respect to matters or questions arising under this Agreement or the Note Policy, as the case may be, which shall not be inconsistent with the provisions of this Agreement, (v) to add or amend any provisions of this Agreement as required by any Rating Agency or any other nationally recognized statistical rating agency in order to maintain or improve any rating of the Class A Notes (it being understood that, after obtaining the ratings in effect on the Closing Date, neither the Indenture Trustee, the Seller, the Depositor nor the Servicer is obligated to obtain, maintain or improve any such rating), or (vi) to amend the definition of Specified O/C Amount; provided however, that as evidenced by an Opinion of Counsel (at the expense of the party requesting such amendment) in each case such action shall not, (1) have any material adverse tax consequence with respect to any Class A Noteholder, any Certificateholder, the Insurer or the Trust or (2) adversely affect in any material respect the interest of any Class A Noteholder, Certificateholder or the Insurer, provided, further, that the amendment shall be deemed not to adversely affect in any material respect the interests of the Class A Noteholders or the Insurer, and no Opinion of Counsel to that effect shall be required by this clause (2) if the Person requesting the amendment obtains a letter from the Rating Agency stating that the amendment would not result in the downgrading or withdrawal of the respective ratings then assigned to the Class A Notes without regard to the Note Policy. Notwithstanding anything to the contrary in this Section 11.01(a), if at the time the parties hereto propose to enter into an amendment under this Section 11.01(a) (except an amendment to cure any ambiguity or to correct any provision of this Agreement) the Trust is required to be a Qualifying SPE (as the Seller shall notify the Indenture Trustee in writing) in order for the Seller to continue to account for the transfer of the Mortgage Loans under this Sale and Servicing Agreement as a sale under SFAS 140 and the Seller’s desire to continue to account for such transfer as a sale, then prior to the time that the parties enter into such amendment the Trust shall deliver to the Indenture Trustee an Accountant’s Opinion which states that such amendments would not “significantly change” (within the meaning of SFAS 140) the Permitted Activities of the Trust so as to cause the Trust to fail to qualify as a Qualifying SPE.

     (b)     This Agreement also may be amended from time to time by the Seller, the Servicer, the Depositor and the Indenture Trustee, with the consent of the Class A Noteholders and with the consent of the Insurer to the extent that Class A Notes are outstanding or any amounts are owed to the Insurer that have not been paid, or, if no Class A Note is outstanding at the time of such amendment, the Holders of the Senior Class of Certificates representing not less than 51% of the related Certificate Principal Balance, for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Agreement or of

modifying in any manner the rights of the Class A Noteholders, the Certificateholders or the Transferor in respect of the Transferor Interest; provided, however, that no such amendment shall (i) reduce in any manner the amount of, or delay the timing of, payments or distributions on the Class A Notes or Certificates or distributions or payments under the Note Policy which are required to be made on the Class A Notes without the consent of all Class A Noteholders or Certificateholders affected by such amendment or (ii) reduce the aforesaid percentage required to consent to any such amendment, without the consent of all Holders of the related Class of Certificates affected by such amendment then outstanding.

     Prior to the execution of any such amendments described in (a) and (b) above, the Indenture Trustee shall furnish written notification of the substance of such amendment to each Rating Agency. In addition, promptly after the execution of any such amendment made with the consent of the Class A Noteholders or the Senior Class of Certificateholders, as applicable, the Indenture Trustee shall furnish written notification of the substance of such amendment to each Certificateholder and Class A Noteholder and fully executed original counterparts of the instruments effecting such amendment to the Insurer.

     (c)     It shall not be necessary for the consent of the Class A Noteholders or the Certificateholders under this Section 11.01 to approve the particular form of any proposed amendment, but it shall be sufficient if such consent shall approve the substance thereof. The manner of obtaining such consents and of evidencing the authorization of the execution thereof by the Class A Noteholders and the Certificateholders shall be subject to such reasonable requirements as the Indenture Trustee may prescribe.

     Prior to the execution of any amendment to this Agreement, the Indenture Trustee shall be entitled to receive and conclusively rely upon an Opinion of Counsel stating that the execution of such amendment is authorized or permitted by this Agreement and all conditions precedent to the execution of such amendment have been met. The Indenture Trustee may, but shall not be obligated to, enter into any such amendment which affects the Indenture Trustee’s own rights, duties, indemnities or immunities under this Agreement.

     Section 11.02     Recordation of Agreement.     To the extent permitted by applicable law, this Agreement, or a memorandum thereof if permitted under applicable law, is subject to recordation in all appropriate public offices for real property records in all of the counties or other comparable jurisdictions in which any or all of the Mortgaged Properties are situated, and in any other appropriate public recording office or elsewhere, such recordation to be effected by the Servicer at the Servicer’s expense on direction of the Indenture Trustee acting at the direction of the Majority Holders, but only when accompanied by an opinion of counsel delivered by counsel to the Majority Holders to the effect that such recordation materially and beneficially affects the interests of the Class A Noteholders or is necessary for the administration or servicing of the Mortgage Loans.

     Section 11.03     Duration of Agreement.     This Agreement shall continue in existence and effect until terminated as herein provided.
