(iv) commercial paper and demand notes (having original maturities of not more than 365 days) of any corporation incorporated under the laws of the United States or any state thereof which on the date of acquisition has been rated by each Rating Agency in its highest short-term rating available; provided that such commercial paper shall have a remaining maturity of not more than 30 days;

Additional Balances shall be included in the related Principal Balance transferred to the Trust pursuant to this Section 2.01 and therefore will be part of the corpus of the Trust.

The Seller, the Depositor and the Trust agree to take or cause to be taken such actions (including without limitation the filing of the UCC-1 financing statements in the States of California, in the case of the Seller, and the State of Delaware, in the case of the Depositor (which shall have been filed on or before the Closing Date) describing the Cut-off Date Principal Balances and Additional Balances related to the Mortgage Loans, and naming the Seller as debtor and the Depositor as secured party, in the case of the Seller, and naming the Depositor as debtor and the Trust as secured party, in the case of the Depositor, and any amendments to such UCC-1 financing statements required to reflect a change in the name or corporate structure of the Seller, the Depositor, or the Trust, as the case may be, or the filing of any additional financing statement due to the change in the jurisdiction of formation of the Seller, the Depositor or the Trust, as the case may be, within 30 days of any event necessitating such filing) as are necessary to perfect and protect the Depositor’s interest in the case of the Seller and the Trust and the Insurer’s interest in the case of the Depositor, in each case describing Cut-off Date Principal Balance and the Additional Balances related to the Mortgage Loans, the remainder of the trust estate and the proceeds thereof. In addition, the Servicer agrees to file continuation statements with respect to such UCC-1 financing statements as required and as long as this Agreement remains outstanding with such authorization and information as may be necessary to make such filing to be provided by the applicable parties.

In the event any loss is suffered by the Insurer or the Indenture Trustee, on behalf of the Trust, in respect of any Mortgage Loan, as a result of a failure by the Seller or the Depositor to file the UCC-1 financing statements when required to perfect or maintain the perfection of the Indenture Trustee’s security interest hereunder and afford it first priority, the Seller shall, on the Business Day next preceding the Payment Date in the month following the Collection Period during which such loss occurred, purchase such Mortgage Loan.

(d) Prior to the last day of each Collection Period preceding the commencement of the Rapid Amortization Period, the Holder of the Class L Certificate shall purchase the Additional Balance Advance Amount for the related Payment Date, if any, and the Seller shall deliver to the Indenture Trustee and the Holder of the Class L Certificates two Business Days prior to the following Servicer Remittance Date an Advance Notice including the aggregate amount of the expected Additional Balance Advance Amount for that date. Upon receipt of such notice and in any event no later than two Business Days prior to the following Payment Date, the Holder of the Class L Certificate shall make an advance to the Trust in the amount specified in such Advance Notice by depositing such amount into the Reserve Account. The Indenture Trustee shall cause such amount to be remitted to the Seller on such following Payment Date. In addition, on and after the first day of the Collection Period in which the commencement of the Rapid Amortization Period occurs, the Holder of the Class L Certificate shall purchase Additional Balances that are transferred to the Trust (as such Additional Balances are conveyed and in the amounts specified by the Servicer) by depositing into the Reserve Account the amount of the Draws relating to such Additional Balances, which amount shall be disbursed by the Indenture Trustee to the Seller. The Class Principal Balance of the Class L Certificates will be increased by the amount of any such purchased Additional Balance Advance Amounts or Additional Balances, as applicable, as described in Section 2.01(c) above.

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 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.

The Indenture Trustee shall determine whether such documents are executed and endorsed, but shall be under no duty or obligation to inspect, review or examine any such documents, instruments, certificates or other papers to determine that the same are valid, binding, legally effective, properly endorsed, genuine, enforceable or appropriate for the represented purpose or that they have actually been recorded or are in recordable form or that they are other than what they purport to be on their face. The Indenture Trustee shall not have any responsibility for verifying the genuineness or the legal effectiveness of or authority for any signatures of or on behalf of any party or endorser.

(h) If in the course of the review described in paragraph (g) above the Indenture Trustee discovers any document or documents constituting a part of a Mortgage File that is missing, does not appear regular on its face (i.e., is mutilated, damaged, defaced, torn or otherwise physically altered) or appears to be unrelated to the Mortgage Loans identified in the Mortgage Loan Schedule, as applicable (each, a “Material Defect”), the Indenture Trustee, upon discovering such Material Defect shall promptly identify the Mortgage Loan to which such Material Defect relates in the Interim Certification delivered to each of the Depositor and the Servicer and give notice thereof to the Seller.

(i) Within 180 days following the Closing Date, the Indenture Trustee shall deliver to the Depositor, the Servicer and the Insurer a final certification (the “Final Certification”) substantially in the form attached as Exhibit L evidencing the completeness of the Mortgage Files in its possession or control, with any exceptions noted thereto.

(j) Nothing in this Agreement shall be construed to constitute an assumption by the Trust Estate, the Indenture Trustee, the Administrator, any Custodian or the Noteholders of any unsatisfied duty, claim or other liability on any Mortgage Loan or to any Mortgagor. 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.

(k) 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(g) through (i).

(l) (i) Upon the occurrence of a Recordation Event, the Indenture Trustee shall within 90 days of such Recordation Event submit, at the expense of the Seller, 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 Servicer may provide to the Indenture Trustee and the Insurer an Opinion of Counsel in a form reasonably acceptable to the Owner Trustee, 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 Owner Trustee, the Indenture Trustee or the Securityholders in the related Mortgage. In the event that any such Assignment of Mortgage is lost or returned unrecorded because of a defect therein, the Indenture Trustee shall promptly prepare, at the expense of the Seller, a substitute Assignment of Mortgage or cure such defect, as the case may be, and thereafter the Indenture Trustee shall, at the expense of the Seller, submit each such Assignment of Mortgage for recording.

(ii) With respect to each MERS Mortgage Loan, the Servicer shall, at the expense of the Depositor, take such actions as are necessary to cause the Indenture Trustee to be clearly identified as the owner of each such Mortgage Loan on the records of MERS for purposes of the system of recording transfers of beneficial ownership of mortgages maintained by MERS.

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 Noteholders, the Indenture Trustee or the Certificateholders.

The Servicer, promptly following the transfer of (i) a Mortgage Loan with a Material Defect 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.

(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, provided that no substitution pursuant to Section 2.02 or 2.04 shall be made more than two years after the Closing Date unless the Seller delivers to the Indenture Trustee and the Insurer (so long as the Notes are Outstanding or any Reimbursement Amounts remain due and owing to the Insurer) an Opinion of Counsel, which Opinion of Counsel shall not be at the expense of either the Indenture Trustee or the Trust Fund, addressed to the Indenture Trustee and the Insurer (so long as the Notes are Outstanding or any Reimbursement Amounts remain due and owing to the Insurer), to the effect that such substitution will not (i) result in the imposition of the tax on “prohibited transactions” on the Trust Fund or contributions after the Startup Date, as defined in Sections 860F(a)(2) and 860G(D) of the Code, respectively, or (ii) cause any REMIC created under the Trust Agreement to fail to qualify as a REMIC at any time that any Notes are outstanding. A substitution pursuant to Section 2.02 or 2.04 that is made within two years after the Closing Date to replace a “defective obligation” within the meaning of Section 860G(a)(4) of the Code shall not require the Seller to deliver to the Indenture Trustee an Opinion of Counsel. 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. On such Determination Date (the “Substitution Date”), the Seller shall deliver to the Insurer, the Servicer, the Depositor and the Indenture Trustee (1) a list of the Eligible Substitute Mortgage Loans to be substituted for the Defective Mortgage Loans, (2) a list of the Defective Mortgage Loans to be substituted for by such Eligible Substitute Mortgage Loans, (3) if such substitution is more than two years after the Closing Date, an Opinion of Counsel that the substitution of the Eligible Substitute Mortgage Loans will not (A) result in the imposition of the tax on “prohibited transactions” on the Trust or (B) cause any REMIC created under the Trust Agreement to fail to qualify as a REMIC at any time the Notes are outstanding, (4) an Officer’s Certificate (A) stating that no Event of Servicer Termination shall have occurred and be continuing, (B) stating that all conditions precedent to such substitution specified in subsection (a) have been satisfied and attaching as an exhibit a supplemental Mortgage Loan schedule (the “Supplemental Mortgage Loan Schedule”) setting forth the same type of information as appears on the Mortgage Loan Schedule and representing as to the accuracy thereof and (C) confirming that the representations

and warranties contained in Section 2.04 are true and correct in all material respects with respect to the Eligible Substitute Mortgage Loans on and as of such Determination Date, provided that remedies for the inaccuracy of such representations are limited as set forth in Sections 2.02, 2.04 and this Section 2.05 and (5) a certificate stating that cash in the amount of the related Substitution Adjustment, if any, has been deposited to the Collection Account; 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 Substitution Adjustment referred to in clause (d) of the definition thereof to the extent such amount is incurred by the Insurer. 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 Collection 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 Collection 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 Collection 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 Noteholders, the Certificateholders or the Insurer.

Section 2.06 Tax Treatment. The Trust shall be treated as comprising two segregated accounts each of which will be a real estate mortgage investment conduit (each a “REMIC” or, in the alternative, the “Lower Tier REMIC” and the “Upper Tier REMIC”); each of the Notes and the Class B Certificates shall represent ownership of a regular interest in the Upper Tier

REMIC; the Class L Certificate shall represent the sole class of residual interest in the Lower Tier REMIC; and the Class R Certificate represents ownership of the sole class of residual interest in the Upper Tier REMIC.

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 Card Management Corporation and First Data Resources, Inc. and any other institution which (i) is in compliance with the laws of each state necessary to

enable it to perform its obligations under such Subservicing Agreement, and (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 Noteholders and the Certificateholders 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 Servicer 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 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 Noteholder and each Certificateholder, 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 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)(ix), 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)(ix); 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) Except as is set forth in the following sentence, the Servicer may not modify any Mortgage Loan unless that Mortgage Loan is in default or if default is reasonably foreseeable, and if the Servicer has determined the modification of that Mortgage Loan to be in the best interests of the Noteholders and the Insurer. In addition, the Servicer may modify a Mortgage Loan that is not in default and default is not reasonably foreseeable if it has delivered to the Indenture Trustee and the Insurer (so long as the Notes are Outstanding or any Reimbursement Amounts remain due and owing to the Insurer) an Opinion of Counsel to the effect that such modification would not cause any REMIC created under the Trust Agreement to fail to qualify as a REMIC or result in the imposition of any prohibited transaction tax; provided it complies with accepted servicing practices of prudent mortgage loan servicers and no rate modification is greater than 0.25% per annum on any Mortgage Loan, and provided that the modification does not materially and adversely affect the interests of the Noteholders, the Certificateholders or the Insurer (taking into account the aggregate effect of all previous modifications to date).

The Servicer’s ability to permit or effect servicing modifications contemplated by this clause (h) of Section 3.01 shall be subject to the following limitations:

(i) Any amounts added to the credit limit of a Mortgage Loan will be required to be fully amortized over the remaining term, or the extended term, of the Mortgage Loan.

(ii) The final maturity of any Mortgage Loan may not be extended beyond the third Payment Date prior to the Final Scheduled Payment Date.

(iii) The aggregate current principal balance of all Mortgage Loans subject to modifications can be no more than 3.5% of the aggregate principal balance of the Mortgage Loans as of the Cut-off Date, but this limit may be increased from time to time with the consent of the Insurer.

(iv) The Servicer covenants and agrees to indemnify the Trust Fund against any liability for any taxes (including prohibited transaction taxes) and any related interest, additions, and penalties imposed on the Trust Fund established hereunder as a result of any modification of a Mortgage Loan effected pursuant to this Section 3.01.

(v) With respect to any Mortgage Loan that is modified to increase the Credit Limit thereof resulting in a higher Combined Loan-to-Value Ratio, (i) the aggregate Principal Balance of all Mortgage Loans so modified shall not exceed 10% of the Cut-off Date Principal Balance, and (ii) the increased Combined Loan-to-Value Ratio for any Mortgage Loan so modified may not exceed 100%; provided, in any case, the limitation set forth in clause (iii) above has been satisfied in connection with any such modification.

(vi) The aggregate current principal balance of all Mortgage Loans that can have a Margin decrease applied to them can be no more than 10% of the aggregate principal balance of the Mortgage Loans as of the Cut-off Date.

(i) If the Mortgage relating to a Mortgage Loan was not subject to a Senior Lien on the Cut-off Date, then the Servicer may not consent to the placing of a lien senior to that of the Mortgage on the related Mortgaged Property. If the Mortgage relating to a Mortgage Loan was subject to a Senior Lien on the Cut-off Date, then the Servicer may consent to the refinancing of such prior Senior Lien after obtaining an appraisal of the Mortgaged Property provided that such refinancing (i) either (x) does not result in the Combined Loan-to-Value Ratio of such Mortgage Loan exceeding the Combined Loan-to-Value Ratio of such Mortgage Loan prior to such refinancing; or (y) does not result in the Combined Loan-to-Value Ratio of such Mortgage Loan exceeding the Combined Loan-to Value Ratio that would have permitted such Mortgage Loan to remain in the same pricing category in connection with the Servicer’s underwriting criteria; and (ii) does not result in the Combined Loan-to-Value Ratio of such Mortgage Loan exceeding 100%.

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) subject to Section 3.13, waive any Early Termination Fee 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.

(b) The Servicer shall establish and maintain an Eligible Account (the “Collection Account”) entitled “Deutsche Bank National Trust Company, in trust for the registered holders of IndyMac Home Equity Mortgage Loan Asset-Backed Trust, Series 2006-H4.” 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 (excluding scheduled interest payments due on or prior to the Cut-off Date) and prior to the Closing Date, and thereafter, subject to Section 3.02(c), deposit within two Business Days following receipt thereof, the following payments and collections received or made by it (without duplication) to the Collection Account:

(i) all payments received by the Servicer after the Cut-off Date on account of principal on the Mortgage Loans;

(ii) all payments, net of related Servicing Fees, received by the Servicer after the Cut-off Date on account of interest on the Mortgage Loans;

(iii) all Insurance Proceeds and Liquidation Proceeds;

(iv) all Net Recoveries;

(v) all Early Termination Fees;

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

(vii) the Purchase Price of any Mortgage Loan and the amount of any Substitution Adjustment paid by a Seller during the related Collection Period pursuant to Sections 2.02, 2.04 and 2.05;

(viii) all Released Mortgaged Property Proceeds; and

(ix) any amount required to be deposited therein pursuant to Section 3.02(c) 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.

(c) The Servicer shall use its best efforts to cause the institution maintaining the Collection Account to invest only the Interest Collections on deposit in the Collection Account attributable to the Mortgage Loans in Eligible Investments which shall mature not later than the Servicer Remittance Date next following the date of such investment and which shall not be sold or disposed of prior to their maturities. All income and gain realized from any such investment shall be for the benefit of the Servicer as additional servicing compensation and shall be subject to its withdrawal or order from time to time. The amount of any losses incurred in respect of any such investments attributable to the investment of amounts in respect of the Mortgage Loans shall be deposited in the Collection Account by the Servicer out of its own funds immediately as realized without any right of reimbursement.

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;

(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 Collection Period then in the Collection Account;

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

(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 11 U.S.C. 101 et seq., as amended in accordance with a final, nonappealable order of a court having competent jurisdiction;

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

(v) 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, including collections received on any Defective Mortgage Loan that has been repurchased by the Seller pursuant to Section 2.04 or substituted for by the Seller pursuant to Section 2.05 that should be paid to the Seller pursuant to Article II;

(vi) to pay the Servicer the servicing compensation for the related Collection Period that it is entitled to receive pursuant to Section 3.09 herein;

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

(viii) 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

(ix) to clear and terminate the Collection Account upon the termination of this Agreement.

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 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 Mortgage Loan 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 Mortgage Loan from time to time, (ii) the combined principal balance owing on such Mortgage Loan and any mortgage loan senior to such Mortgage Loan 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 Mortgage Loan and any mortgage loan senior to such Mortgage Loan 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 Mortgage Loan 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 Mortgage Loan, 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.

If such insurance policy contains a deductible clause, the Servicer shall, in the event that there shall not have been maintained on the related Mortgage Property an insurance policy comply with this Section, and there shall have been a loss that would have been covered by such insurance policy, deposit into the Collection Account the amount not otherwise payable under such insurance policy because of such deductible clause.

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 may contain a deductible clause on terms substantially equivalent to those commercially available and maintained by comparable servicers. 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. In the event the Trust acquires ownership of any REO Property in respect of any Mortgage Loan, the deed or certificate of sale shall be issued to the Indenture Trustee, or to its nominee, on behalf of the Securityholders. The Servicer shall use its reasonable best efforts to sell, any REO Property as expeditiously as possible and in accordance with the provisions of this Agreement, as applicable, but in all events within the time period, and subject to the conditions set forth in Section 5.09 and prior to the close of the third taxable year after its acquisition by the Trust unless the Indenture Trustee and (so long as any Notes are Outstanding or any Reimbursement Amounts remain due and owing to the Insurer and no Insurer Default has occurred and is continuing) the Insurer shall have been supplied with an Opinion of Counsel to the effect that the holding by the Trust of such REO Property subsequent to such three-year period will not result in the imposition of taxes on “prohibited transactions” of any REMIC created under the Trust Agreement as defined in section 860F of the Code or cause any REMIC created hereunder to fail to qualify as a REMIC at any time that any Notes or Certificates are Outstanding, in which case the Trust may continue to hold such REO Property (subject to any conditions contained in such Opinion of Counsel and the other requirements of this Section 3.07(a)). Pursuant to its efforts to sell such REO Property, the Servicer shall protect and conserve, such REO Property in the manner and to such extent required by this Agreement, subject to Section 5.09 hereof. The decision of the Servicer to foreclose, or to continue the foreclosure process, on a defaulted Mortgage Loan shall be subject to a determination by the Servicer that the related Mortgaged Property will not fail to qualify as “foreclosure property” within meaning of Section 860G(a)(8) of the Code and that the proceeds of such foreclosure would more likely than not exceed the costs and expenses of bringing such a proceeding and liquidating the REO Property expected to be obtained through such foreclosure. Notwithstanding any other provision of this Agreement, no Mortgaged Property acquired by the Trust shall be rented (or allowed to continue to be rented) or otherwise used for the production of income by or on behalf of the Trust in such a manner or pursuant to any terms that would (i) cause such Mortgaged Property to fail to qualify as “foreclosure property” within the meaning of Section 860G(a)(8) of the Code or (ii) subject any REMIC created under the Trust Agreement to the imposition of any federal, state or local income taxes on the income earned from such Mortgaged Property, unless the Servicer has agreed to in demnify and hold harmless the Trust and the Trust Estate with respect to the imposition of any such taxes..

The Servicer shall cause to be deposited, within the time period specified in Section 3.02(b), as applicable, in the Collection Account, all revenues net of Servicing 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 Noteholders, the Certificateholders, 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), as applicable, net of any related unreimbursed Servicing Advances (without duplication of amounts paid pursuant to Section 3.03(vi)), 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 (on behalf of the Indenture Trustee pursuant to the authorization contained in Section 3.01(f) 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 I, 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 and Foreclosure Profits 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.

Section 3.10 Annual Statement as to Compliance. The Servicer shall deliver to the Indenture Trustee (via electronic mail to ***@***), the Depositor, the Insurer (so long as the Notes are Outstanding or any Reimbursement Amounts remain due and

owing to the Insurer) and the Rating Agencies on or before March 15 of each year, commencing in 2007, unless and until a Form 15 Suspension Notice shall have been filed an officer’s certificate, an officer’s certificate in the form of Exhibit C hereof, certifying that with respect to the period ending December 31st of the prior year: (i) the Servicer or such Servicing Officer, as applicable, has reviewed the activities of the Servicer during the preceding calendar year or portion thereof and its performance under this Agreement and (ii) to the best of the Servicer’s or such Servicing Officer’s knowledge, as applicable based on such review, the Servicer has performed and fulfilled its duties, responsibilities and obligations under this Agreement in all material respects throughout such year, or, if there has been a default in the fulfillment of any such duties, responsibilities or obligations, specifying each such default known to such Servicing Officer and the nature and status thereof. Copies of any such statement shall be provided by the Indenture Trustee to any Noteholder and to any Person identified to the Indenture Trustee as a prospective transferee of a Note, upon request at the expense of the requesting party, provided such statement is delivered by the Servicer to the Indenture Trustee. In addition to the foregoing, the Servicer will, to the extent reasonable, give any other servicing information required by the Commission pursuant to applicable law. The Servicer shall indemnify and hold harmless the Depositor and its officers, directors and Affiliates from and against any actual losses, damages, penalties, fines, forfeitures, reasonable and necessary legal fees and related costs, judgments and other costs and expenses that such Person may sustain based upon a breach of the Servicer’s obligations under this Section 3.10.

Section 3.11 Assessment of Compliance and Attestation Report.

The Servicer shall service and administer the Mortgage Loans in accordance with all requirements of the Servicing Criteria applicable to the Servicer (as set forth in Exhibit P hereto). Pursuant to Rules 13a-18 and 15d-18 of the Exchange Act and Item 1122 of Regulation AB, the Servicer, unless a Form 15 Suspension Notice shall have been filed, shall deliver to the Indenture Trustee and the Insurer (so long as the Notes are Outstanding or any Reimbursement Amounts remain due and owing to the Insurer), via electronic mail to ***@***, on or before March 15th of each calendar year beginning in 2007, a report regarding the Servicer’s assessment of compliance (an “Assessment of Compliance”) with the Servicing Criteria during the preceding calendar year. The Assessment of Compliance must be reasonably satisfactory to the Indenture Trustee, and as set forth in Regulation AB, the Assessment of Compliance must contain the following:

(a) A statement by such officer of its responsibility for assessing compliance with the Servicing Criteria applicable to the Servicer;

(b) A statement by such officer that such officer used the Servicing Criteria, and which will also be attached to the Assessment of Compliance, to assess compliance with the Servicing Criteria applicable to the Servicer;

(c) An assessment by such officer of the Servicer’s compliance with the applicable Servicing Criteria for the period consisting of the preceding calendar year, including disclosure of any material instance of noncompliance with respect thereto during such period,

which assessment shall be based on the activities it performs with respect to asset-backed securities transactions taken as a whole involving the Servicer, that are backed by the same asset type as the Mortgage Loans;

(d) A statement that a registered public accounting firm has issued an attestation report on the Servicer’s Assessment of Compliance for the period consisting of the preceding calendar year; and

(e) A statement as to which of the Servicing Criteria, if any, are not applicable to the Servicer, which statement shall be based on the activities it performs with respect to asset-backed securities transactions taken as a whole involving the Servicer, that are backed by the same asset type as the Mortgage Loans.

Such report at a minimum shall address each of the Servicing Criteria specified on Exhibit P hereto which are indicated as applicable to the Servicer.

On or before March 15th of each calendar year beginning in 2007, the Servicer shall furnish to the Indenture Trustee and the Insurer (so long as the Notes are Outstanding or any Reimbursement Amounts remain due and owing to the Insurer) a report (an “Attestation Report”) by a registered public accounting firm that attests to, and reports on, the Assessment of Compliance made by the Servicer, as required by Rules 13a-18 and 15d-18 of the Exchange Act and Item 1122(b) of Regulation AB, which Attestation Report must be made in accordance with standards for attestation reports issued or adopted by the Public Company Accounting Oversight Board.

The Servicer shall cause and any Subservicer, and each subcontractor determined by the Servicer to be “participating in the servicing function” within the meaning of Item 1122 of Regulation AB, to deliver to the Indenture Trustee and the Depositor an Assessment of Compliance and Attestation Report as and when provided above.

Such Assessment of Compliance, as to any Subservicer, shall at a minimum address each of the Servicing Criteria specified on Exhibit P hereto which are indicated as applicable to any “primary servicer.” Notwithstanding the foregoing, as to any subcontractor, an Assessment of Compliance is not required to be delivered unless it is required as part of a Form 10-K with respect to the Trust Fund.

If the Servicer cannot deliver any Assessment of Compliance or Attestation Report by March 15th of such year, the Indenture Trustee, at its sole option, may permit a cure period for the Servicer to deliver such Assessment of Compliance or Attestation Report, but in no event later than March 25th of such year.

Failure of the Servicer to timely comply with this Section 3.11 may be deemed an Event of Servicer Termination. The Indenture Trustee shall, with the consent of the Depositor, in addition to whatever rights the Indenture Trustee may have under this Agreement and at law or equity or to damages, including injunctive relief and specific performance, give notice to Noteholders and the Insurer (so long as the Notes are Outstanding or any Reimbursement

Amounts remain due and owing to the Insurer and no Insurer Default has occurred and is continuing) that each has ten Business Days to object. If no such objection is received, the Indenture Trustee shall immediately terminate all the rights and obligations of the Servicer under this Agreement and in and to the Mortgage Loans and the proceeds thereof without compensating the Servicer for the same. This paragraph shall supersede any other provision in this Agreement or any other agreement to the contrary.

The Indenture Trustee shall also provide an Assessment of Compliance and Attestation Report, as and when provided above, which shall at a minimum address each of the Servicing Criteria specified on Exhibit P hereto which are indicated as applicable to the “trustee.”

Section 3.12 Access to Certain Documentation and Information Regarding the Mortgage Loans. The Servicer shall provide to the Indenture Trustee, the Insurer, 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 Early Termination Fees

(a) Servicer shall not waive any part of any Early Termination Fee unless the waiver relates to a default or a reasonably foreseeable default, the collection of any Early Termination Fee would violate any relevant law or regulation or the waiving of the Early Termination Fee would otherwise benefit the Trust Fund and it is expected that the waiver would maximize recovery of total proceeds taking into account the value of the Early Termination Fee and related Mortgage Loan and doing so is standard and customary in servicing similar Mortgage Loans (including any waiver of a Early Termination Fee in connection with a refinancing of a Mortgage Loan that is related to a default or a reasonably foreseeable default). The Servicer shall not waive a Early Termination Fee in connection with a refinancing of a Mortgage Loan that is not related to a default or a reasonably foreseeable default.

(c) The Seller represents and warrants to the Depositor and the Indenture Trustee, as of the Closing Date, that the information in the Mortgage Loan Schedule (including the attached Early Termination Fee summary) is complete and accurate in all material respects at the dates as of which the information is furnished and each Early Termination Fee is permissible and enforceable in accordance with its terms under applicable state law.

(d) Upon discovery by the Seller or a Responsible Officer of the Indenture Trustee of a breach of the foregoing clause (b) that materially and adversely affects right of the Holders of

the Class L Certificate to any Early Termination Fee, the party discovering the breach shall give prompt written notice to the other parties. Within sixty (60) days of the earlier of discovery by the Servicer or receipt of notice by the Servicer of breach, the Servicer shall cure the breach in all material respects or shall pay into the Collection Account the amount of the scheduled Early Termination Fee, less any amount previously collected and paid by the Servicer into the Collection Account. If the covenant made by the Servicer in clause (a) above is breached, the Servicer must pay into the Collection Account the amount of the waived Early Termination Fee.

Section 3.14 Commission Reporting.

(a) Unless and until a Form 15 Suspension Notice shall have been filed, the Indenture Trustee shall, within 15 days after each Distribution Date and in accordance with industry standards, file with the Commission via the Electronic Data Gathering and Retrieval System (“EDGAR”), a Distribution Report on Form 10-D (the “Distribution Report”) with a copy of the statement to be furnished by the Indenture Trustee to the Noteholders for such Distribution Date and, if applicable, including the information required by each of the items set forth in Part II thereof, subject to the receipt of the information set forth in (f) below, in the case of information not required to be provided by the Indenture Trustee.

Any such amendment may result in the reduction of the reports executed by and filed on behalf of the Depositor under the Exchange Act.

(n) Each of the parties acknowledges and agrees that the purpose of Sections 3.10, 3.11 and this Section 3.14 of this Agreement is to facilitate compliance by the Depositor with the provisions of Regulation AB.

The Servicer shall, beginning in 2007, 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, provided that pursuant to which assumption agreement, such person shall become liable under the Mortgage Note and, unless prohibited by applicable law, the Mortgagor shall remain liable thereon and, in connection with such assumption, no material term of the Mortgage Note may be changed. 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. The Servicer will ensure that payment of hazard insurance premiums and real estate taxes with respect to the Mortgage Loans are made and will make Servicing Advances with respect to required payments of hazard insurance premiums and real estate taxes to the extent necessary to

avoid the loss of a Mortgaged Property due to a tax sale or the foreclosure thereof as a result of a tax lien.

Section 3.18 Servicing Advances. Notwithstanding anything herein to the contrary, no Servicing Advance shall be required to be made hereunder by the Servicer if such 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 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 3.19 Allocation of Charge-Off Amounts.

(a) On each Payment Date, the Servicer shall calculate the amount of Charge-off Amounts for the preceding Collection Period, and shall include such calculation in its Servicing Certificate.

Section 4.01 Claims upon the Policy.

(a) As soon as possible, and in no event later than 10:00 a.m. 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 Policy (the “Notice”) in the event that the Insured Payment for such Payment Date is an amount greater than zero. The Notice shall specify the amount of the Insured Payment and shall constitute a claim for an Insured Payment pursuant to the Policy. Upon receipt of an Insured Payment on behalf of the Holders of the Notes under the Policy, the Indenture Trustee shall deposit such Insured Payment in the Payment Account and shall distribute such Insured Payment on the Payment Date or on the date of receipt by the Indenture Trustee, if received after the Payment Date, to the Noteholders as a payment of interest or principal, as the case may be.

(b) The Indenture Trustee shall keep a complete and accurate record of the amount of interest and principal paid from moneys received under the 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) Subject to the terms of the Policy, if a payment of principal or interest previously paid to a Noteholder is voided under any applicable bankruptcy, insolvency, receivership or similar law in an insolvency proceeding, and as a result, the Indenture Trustee is required to return such voided payment, or any portion of such voided payment, made in respect of the Notes, the Indenture Trustee or any Holder shall furnish to the Fiscal Agent for the Insurer (i) a certified copy of the order requiring the return of a preference payment, (ii) an opinion of counsel satisfactory to the Insurer that such order is final and not subject to appeal, (iii) an assignment in such form as is reasonably required by the Insurer, irrevocably assigning to the Insurer all rights and claims of the Holder relating to or arising under the Notes against the debtor which made such preference payment or otherwise with respect to such preference payment and (iv) appropriate instruments to effect the appointment of the Insurer as agent for such Holder in any legal proceeding related to such preference payment, such instruments being in a form satisfactory to the Insurer; provided, that if such documents are received by the Fiscal Agent for the Insurer after 12:00 p.m., New York City time, on such Business Day, they will be deemed to be received on the following Business Day. Such payments shall be disbursed to the receiver or trustee in bankruptcy named in the final order of the court exercising jurisdiction on behalf of the Holder and not to any Holder directly unless such Holder has returned principal or interest paid on the Notes to such receiver or trustee in bankruptcy, in which case such payment shall be disbursed to such Holder. The Indenture Trustee is not permitted to make a claim on the Trust or on any Noteholder for payments made to any 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 Policy in respect of the Notes shall be deposited to the Payment Account and be used solely to make a payment to the Noteholders.

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 Notes which are made with moneys received pursuant to the terms of the Policy shall not be considered payment of such 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 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 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 Notes to the Holders of such 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 Notes as otherwise set forth herein.

(i) Any failure by the Servicer to furnish to the Indenture Trustee the Mortgage Loan data sufficient to prepare the reports described in Sections 3.19 or 5.03 which continues unremedied for a period of two (2) Business Days after the date upon which written notice of such failure shall have been given to the Servicer by the Indenture Trustee or to the Servicer and the Indenture Trustee by the Insurer (so long as the Notes are Outstanding or any Reimbursement Amounts remain due and owing to the Insurer and no Insurer Default has occurred and is continuing) and, if (i) the Notes are no longer Outstanding and no amounts remain due and owing to the Insurer or (ii) an Insurer Default has occurred and is continuing, by Holders of not less than 25% of the Note Principal Amount of the Notes; or

(ii) Any failure on the part of the Servicer duly to observe or perform in any material respect any other of the covenants or agreements on the part of the Servicer contained in this Agreement which 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 Majority Securityholders or the Insurer; or

(iii) The Servicer shall consent to the appointment of a conservator or receiver or liquidator in any insolvency, readjustment of debt, marshalling of assets and liabilities, voluntary liquidation or similar proceedings of or relating to the Servicer or of or relating to all or substantially all of its property; or

(iv) The Servicer shall admit in writing its inability to pay its debts generally as they become due, file a petition to take advantage of any applicable insolvency or reorganization statute, make an assignment for the benefit of its creditors or voluntarily suspend payment of its obligations; or

(v) The Servicer shall be dissolved, or shall dispose of all or substantially all of its assets, or consolidate with or merge into another entity or shall permit another

entity to consolidate or merge into it, such that the resulting entity does not meet the criteria for a successor servicer as specified herein; or

(vi) If a representation or warranty set forth in Section 2.03 hereof shall prove to be incorrect as of the time made in any respect that materially and adversely affects the interests of the Securityholders or the Insurer, and the circumstance or condition in respect of which such representation or warranty was incorrect shall not have been eliminated or cured within 30 days after the date on which written notice of such incorrect representation or warranty shall have been given to the Servicer by the Indenture Trustee, or to the Servicer and the Indenture Trustee by the Controlling Party; or

(vii) A sale or pledge of any of the rights of the Servicer hereunder or an assignment of this Agreement by the Servicer or a delegation of the rights or duties of the Servicer hereunder shall have occurred in any manner not otherwise permitted hereunder and without the prior written consent of the Controlling Party; or

(viii) After receipt of notice from the Indenture Trustee, any failure of the Servicer to remit to the Indenture Trustee any payment required to be made to the Indenture Trustee for the benefit of Noteholders and the Certificateholders or to the Insurer under the terms of this Agreement on any Servicer Remittance Date which failure continues unremedied for a period of two (2) Business Days after the date upon which notice of such failure shall have been given to the Servicer by the Indenture Trustee or the Insurer (so long as the Notes are Outstanding or any Reimbursement Amounts remain due and owing to the Insurer and no Insurer Default has occurred and is continuing).

If an Event of Servicer Termination described in clauses (i) through (viii) of this Section 7.01 shall occur, then, in each and every case, subject to applicable law, so long as any such Event of Servicer Termination shall not have been remedied within any period of time prescribed by this Section 7.01, the Indenture Trustee, by notice in writing to the Servicer may, with the consent of the Insurer, and shall at the direction of the Insurer (or if an Insurer Default has occurred and is continuing, at the direction of the Noteholders evidencing not less than 66-2/3% of the aggregate Note Principal Amount of the Notes), terminate all of the rights and obligations of the Servicer hereunder and in and to the Mortgage Loans and the proceeds thereof.

On or after the receipt by the Servicer of such written notice, all authority and power of the Servicer, and only in its capacity as Servicer under this Agreement, whether with respect to the Mortgage Loans or otherwise, shall pass to and be vested in the Indenture Trustee pursuant to and under the terms of this Agreement; and the Indenture Trustee is hereby authorized and empowered to execute and deliver, on behalf of the defaulting Servicer as attorney-in-fact or otherwise, any and all documents and other instruments, and to do or accomplish all other acts or things necessary or appropriate to effect the purposes of such notice of termination, whether to complete the transfer and endorsement or assignment of the Mortgage Loans and related documents or otherwise. The defaulting Servicer agrees to cooperate with the Indenture Trustee in effecting the termination of the defaulting Servicer’s responsibilities and rights hereunder as Servicer including, without limitation, notifying the Subservicers of the assignment of the master

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 Securities or thereafter received with respect to the Mortgage Loans. The Servicer being terminated 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 Agreement, if necessary.

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; provided however such right of reimbursement shall be net of any amounts owed by the terminated Servicer and required to be reimbursed pursuant to Section 3.01(f) hereof.

(b) In addition, upon the occurrence of any Insurance Agreement Event of Default, as defined herein, and upon the direction of the Insurer in connection therewith (so long as the Notes are outstanding or Reimbursement Amounts remain due and owing to the Insurer and no Insurer Default has occurred and is continuing), 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 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(c) 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 Notes, without regard to the Policy, as evidenced in writing by each Rating Agency.

Section 7.03 Waiver of Defaults. While the Notes are outstanding, the Insurer or the Majority Securityholders with the consent of the Insurer (so long as the Notes are Outstanding or any Reimbursement Amounts remain due and owing to the Insurer and no Insurer Default has occurred and is continuing) may by written notice to the Indenture Trustee, on behalf of such Noteholders, waive any events permitting removal of the Servicer as servicer pursuant to this Article VII, provided, however, that the Insurer and the Majority Securityholders may not waive a default in making a required payment on a Note without the consent of 100% of the Holders of such Notes. Upon any waiver of a past default, such default shall cease to exist and any Event of Servicer 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 Notes are no longer outstanding and no Reimbursement Amounts are then due and owing to the Insurer and no Insurer Default has occurred and is continuing, the Majority Securityholders may by written notice to the Indenture Trustee, on behalf of all Noteholders, 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 Servicer 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 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 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 the Noteholders and distributions to the Certificateholders after the Final Scheduled 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 Scheduled Payment Date.

(b) On any Payment Date on which the Note Principal Amount, prior to giving effect to payments on such date, is less than or equal to 10% of the aggregate Initial Note Principal Amount (such date, the “Optional Redemption Date”), the Servicer may, at its option, terminate this Agreement, subject to (i) the consent of the Insurer if such termination will cause a draw on the Policy and (ii) no Reimbursement Amounts remaining due to the Insurer under the Insurance Agreement, by purchasing, on such Payment Date, all of the outstanding Mortgage Loans and all other property remaining in the Trust. The purchase price will equal the Optional Redemption Price.

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 Optional Redemption 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 Noteholders may surrender their 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 25th day of the month next preceding the month of such final payment specifying (i) the Payment Date upon which final payment on the Notes will be made upon presentation and surrender of the 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 Notes at the office or agency of the Indenture Trustee therein specified.

(d) Upon presentation and surrender of the Notes and the Certificates, the Indenture Trustee shall cause to be paid to the Holders of the 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 Noteholders and the Certificateholders in the order of priority specified in and otherwise pursuant to Section 5.01 for such Payment Date. On the final Payment Date, all amounts on deposit in the Payment Account shall be applied in accordance with Sections 5.01(a) and (b).

(e) In the event that all of the Noteholders and the Certificateholders shall not surrender their 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 Noteholder or Certificateholders to be withdrawn therefrom and credited to the remaining 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 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 Noteholders or Certificateholders to surrender their Notes or Certificates for cancellation and receive the final payment with respect thereto.

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

Section 9.01 Indenture Trustee Not Liable for the Notes or Mortgage Loans. The recitals contained herein and in the Notes shall be taken as the statements of the Servicer and the Seller, as the case may be, and the Indenture Trustee assumes no responsibility for their correctness. The Indenture Trustee makes no representations as to the validity or sufficiency of this Agreement or of the Notes or of any Mortgage Loan or related document, other than with respect to the Indenture Trustee’s execution and authentication of the Notes. The Indenture Trustee shall not be accountable for the use or application by the Servicer of any funds paid to the Servicer in respect of the Mortgage Loans or deposited in or withdrawn from the Collection Account by the Servicer.

Except as provided in Section 2.01(e) and 2.01(l), the Indenture Trustee shall have no responsibility for filing or recording any financing or continuation statement in any public office at any time or to otherwise perfect or maintain the perfection of any security interest or lien granted to it hereunder (unless the Indenture Trustee shall have become the successor Servicer).

The Indenture Trustee executes the Notes not in its individual capacity but solely as Indenture Trustee of the Trust created by this Agreement, in the exercise of the powers and authority conferred and vested in it by this Agreement. Each of the undertakings and agreements made on the part of the Indenture Trustee on behalf of the Trust in the Notes is made and intended not as a personal undertaking or agreement by the Indenture Trustee but is made and intended for the purpose of binding only the Trust.

Notwithstanding anything to the contrary herein, in connection with its activities provided for in this Agreement, the Indenture Trustee shall be entitled to the same rights, protections, immunities and indemnities afforded to it under the terms of the Indenture.

Section 9.02 Indenture Trustee May Own Notes. The Indenture Trustee in its individual or any other capacity may become the owner or pledgee of the Notes and may transact business with the Seller, the Servicer and their affiliates, with the same rights as it would have if it were not the Indenture Trustee.

Section 9.03 Indenture Trustee’s Fees and Expenses. Subject to the side letter, dated December 21, 2006, among the Indenture Trustee, the Seller and the Servicer, the Indenture Trustee Fee shall be paid to the Indenture Trustee, as compensation for its activities hereunder, pursuant to Section 5.01. The Indenture Trustee and any director, officer, employee or agent of the Indenture Trustee shall be indemnified by the Seller and held harmless against any loss, liability or expense (including reasonable attorney’s fees and expenses) incurred in connection with any claim or legal action relating to (a) this Agreement or the Insurance and Indemnity Agreement, (b) the Notes, or (c) the performance of any of the Indenture Trustee’s duties hereunder, other than any loss, liability or expense incurred by reason of willful misfeasance, bad

faith or negligence in the performance of any of the Indenture Trustee’s duties hereunder or incurred by reason of any action of the Indenture Trustee taken at the direction of the Insurer or (i) if the Notes are no longer Outstanding and no Reimbursement Amounts remain due and owing to the Insurer or (ii) an Insurer Default has occurred and is continuing, the Noteholders. Such indemnity shall survive the termination of this Agreement or the resignation or removal of the Indenture Trustee hereunder. Without limiting the foregoing, the Seller covenants and agrees, and except for any such expense, disbursement or advance as may arise from the Indenture Trustee’s negligence, bad faith or willful misconduct, to pay or reimburse the Indenture Trustee, for all reasonable expenses, disbursements and advances incurred or made by the Indenture Trustee in accordance with any of the provisions of this Agreement with respect to: (A) the reasonable compensation and the expenses and disbursements of its counsel not associated with the closing of the issuance of the Notes, (B) the reasonable compensation, expenses and disbursements of any accountant, engineer or appraiser that is not regularly employed by the Indenture Trustee, to the extent that the Indenture Trustee must engage such persons to perform acts or services hereunder, (C) printing and engraving expenses in connection with preparing any Definitive Notes and (D) any other reasonable expenses incurred other than in the ordinary course of its business by the Indenture Trustee in connection with its duties hereunder. Except as otherwise provided herein, the Indenture Trustee shall not be entitled to payment or reimbursement for any routine ongoing expenses incurred by the Indenture Trustee in the ordinary course of its duties as Indenture Trustee hereunder or for any other expenses.

Prior to entering into any amendment without the consent of

Holders pursuant to this paragraph, the Indenture Trustee may require an Opinion of Counsel which shall also be addressed to the Insurer (so long as the Notes are Outstanding or any Reimbursement Amounts remain due and owing to the Insurer) (at the expense of the party requesting such amendment) to the effect that such amendment is permitted under this paragraph. Any such amendment shall be deemed not to adversely affect in any material respect any Holder and the opinion to such effect will not be required to be given, if the Indenture Trustee receives written confirmation from each Rating Agency that such amendment will not cause such Rating Agency to reduce the then current rating assigned to the Notes without taking into account the Policy.

For purposes of this paragraph, references to “Holder” or “Holders” shall be deemed to include, in the case of Book-Entry Notes, the related Note Owners.

(c) Promptly after the execution of any such amendment, the Indenture Trustee shall furnish written notification of the substance of such amendment to each Holder, the Insurer (so long as the Notes are Outstanding or any Reimbursement Amounts remain due and owing to the Insurer and no Insurer Default has occurred and is continuing), the Depositor and to each Rating Agency.

(d) It shall not be necessary for the consent of Holders under this Section 10.01 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 Holders shall be subject to such reasonable regulations as the Indenture Trustee may prescribe.
