This Pooling And Servicing Agreement, dated as of December 1, 2007, among IndyMac MBS, Inc., a Delaware corporation, as depositor (the “Depositor”), IndyMac Bank, F.S.B. (“IndyMac”), a federal savings bank, as seller (in that capacity, the “Seller”) and as servicer (in that capacity, the “Servicer”), and Deutsche Bank National Trust Company, a national banking association, as trustee (in that capacity, the “Trustee”), and as supplemental interest trustee (in that capacity, the “Supplemental Interest Trustee”).

W i t n e s s e t h T h a t

In consideration of the mutual agreements set forth in this Agreement, the parties agree as follows:

P r e l i m i n a r y S t a t e m e n t

The Depositor is the owner of the Trust Fund that is hereby conveyed to the Trustee in return for the Certificates. As provided in this Agreement, the Trustee shall elect that the Trust Fund (exclusive of the Supplemental Interest Trust, the Swap Contract, the Swap Account and any amounts in respect of waived Prepayment Charges paid by the Servicer to the Class P-1 and Class P-2 Certificates, as applicable, pursuant to Section 3.20(b) and any amounts in respect of waived Late Payment Fees paid by the Servicer to the Class L Certificates pursuant to Section 3.21(b)) be treated for federal income tax purposes as comprising three real estate mortgage investment conduits (each, a “REMIC” or, in the alternative, “REMIC 1,” “REMIC 2” and the “Master REMIC”). Each Certificate, other than the Class A-R Certificate, and the uncertificated Class IO Interest retained by Deutsche Bank Securities Inc. will represent ownership of one or more regular interests in the Master REMIC for purposes of the REMIC Provisions. The Class A-R Certificates represent ownership of the sole class of residual interest in each REMIC created under this Agreement. The Master REMIC will hold as assets the several classes of uncertificated REMIC 2 Interests (other than the Class R-2 Interest). REMIC 2 will hold as assets the several classes of uncertificated REMIC 1 Interests (other than the Class R-1 Interest). REMIC 1 will hold as assets all property of the Trust Fund other than the Supplemental Interest Trust, the Swap Contract and the Swap Account. Each REMIC 2 Interest (other than the Class R-2 Interest) is hereby designated as a regular interest in REMIC 2. Each REMIC 1 Interest (other than the Class R-1 Interest) is hereby designated as a regular interest in REMIC 1.

The latest possible maturity date of all REMIC regular interests created in this Agreement shall be the Latest Possible Maturity Date. All amounts in respect of waived Prepayment Charges paid by the Servicer to the Class P-1 and Class P-2 Certificates pursuant to Section 3.20(b) will be treated as paid directly by the Servicer to the Class P-1 and Class P-2 Certificates and not as paid by or through any REMIC created under this Agreement. All amounts in respect of waived Late Payment Fees paid by the Servicer to the Class L Certificates will be treated as paid directly by the Servicer to the Class L Certificates pursuant to Section 3.21(b) and not as paid by or through any REMIC created under this Agreement.

REMIC 1

The REMIC 1 Regular Interests will have the initial principal balance, Pass-Through Rates and corresponding Loan Groups as set forth in the following table:

REMIC 1 Interests	Initial Principal Balance or Notional Amount	Pass-Through Rate	Corresponding Loan Group
A-1 (0.9% of the Subordinated Portion of Loan Group 1)	(1)	(2)	1
B-1 (0.1% of the Subordinated Portion of Loan Group 1)	(1)	(2)	1
C-1 (Excess of Loan Group 1)	(1)	(2)	1
A-2 (0.9% of the Subordinated Portion of Loan Group 2)	(1)	(2)	2
B-2 (0.1% of the Subordinated Portion of Loan Group 2)	(1)	(2)	2
C-2 (Excess of Loan Group 2)	(1)	(2)	2
A-3 (0.9% of the Subordinated Portion of Loan Group 3)	(1)	(2)	3
B-3 (0.1% of the Subordinated Portion of Loan Group 3)	(1)	(2)	3
C-3 (Excess of Loan Group 3)	(1)	(2)	3
1-P	$100	(3)	N/A
1-$100	$100	(4)	N/A
R-1	(5)	(5)	N/A

_______________

(1) Each Class A Interest will have a principal balance initially equal to 0.9% of the Subordinated Portion of its corresponding Loan Group. Each Class B Interest will have a principal balance initially equal to 0.1% of the the Subordinated Portion of its corresponding Loan Group. The initial principal balance of each Class C Interest will equal the excess of the initial aggregate principal balance of its corresponding Loan Group over the initial aggregate principal balances of the Class A and Class B Interests (and of the Class 1-$100 Interest, in the case of the Class C-3 Interest) corresponding to such Loan Group.

(2) The Weighted Average Adjusted Net Mortgage Rate of the Mortgage Loans in the corresponding Loan Group.

(3) The Class 1-P-1 and Class 1-P-2 Interests will not bear interest. The Class 1-P-1 Interests will be entitled to 100% of any Hard Prepayment Charges paid on the Mortgage Loans. The Class 1-P-2 Interests will be entitled to 100% of any Soft Prepayment Charges paid on the Mortgage Loans.

(4) The Weighted Average Adjusted Net Mortgage Rate of the Mortgage Loans in Loan Group 3.

(5) The Class R-1 Interest is the sole class of residual interest in REMIC 1. It has no principal balance and pays no principal or interest.

On each Distribution Date, the Available Funds shall be distributed with respect to the REMIC 1 Interests in the following manner:

(1) Interest is to be distributed with respect to each REMIC 1 Interest according to the formulas described above;

(2) Principal Amounts and Realized Losses will be allocated to make the balances of the Class 1-P-1, Class 1-P-2 and Class 1-$100 Interests equal to the principal balances of the Class P-1, Class P-2 and Class A-R Certificates, respectively, for such Distribution Date.

(3) If a Cross-Over Situation does not exist with respect to any Class of Interests, then Principal Amounts and Realized Losses arising with respect to each Loan Group will be allocated: first to cause the Loan Group’s corresponding Class A and Class B Interests to equal, respectively, 0.9% of the Subordinated Portion and 0.1% of the Subordinated Portion; and second to the Loan Group’s corresponding Class C Interest;

(4) If a Cross-Over Situation exists with respect to the Class A and Class B Interests then:

(a) if the Calculation Rate in respect of the outstanding Class A and Class B Interests is less than the Subordinate Pass-Through Rate, Principal Relocation Payments will be made proportionately to the outstanding Class A Interests prior to any other distributions of principal from each such Loan Group; and

(b) if the Calculation Rate in respect of the outstanding Class A and Class B Interests is greater than the Subordinate Pass-Through Rate, Principal Relocation Payments will be made proportionately to the outstanding Class B Interests prior to any other distributions of principal from each such Loan Group.

In case of either (a) or (b), Principal Relocation Payments will be made so as to cause the Calculation Rate in respect of the outstanding Class A and Class B Interests to equal the Subordinate Pass-Through Rate. With respect to each Loan Group, if (and to the extent that) the sum of (a) the principal payments comprising the Principal Amount received during the Due Period and (b) the Realized Losses on the Mortgage Loans in that Loan Group, are insufficient to make the necessary reductions of principal on the Class A and Class B Interests, then interest will be added to the Loan Group’s other REMIC 1 Interests that are not receiving Principal Relocation Payments, in proportion to their principal balances.

(c) Unless otherwise required to achieve the Calculation Rate, the outstanding aggregate Class A and Class B Interests for all Loan Groups will not be reduced below 1% of the excess of (i) the aggregate Stated Principal Balances of the Mortgage Loans as of the end of any Due Period (reduced by any Principal Prepayments received after the Due Period that are to be distributed on the Distribution Date related to the Due Period)over (ii) the Certificate Balance of the Senior Certificates (excluding the Class A-R Certificates) for all Certificate Groups as of the related Distribution Date (after taking into account distributions of principal on such Distribution Date).

If (and to the extent that) the limitation in paragraph (c) prevents the distribution of principal to the Class A and Class B Interests of a Loan Group, and if the Loan Group’s Class C Interest has already been reduced to zero, then the excess principal from that Loan Group will be paid to the Class C Interests of the other Loan Group, the aggregate Class A and Class B Interests of which are less than 1% of the Subordinated Portion. If the Mortgage Loans in the Loan Group of the Class C Interest that receives such payment has a Weighted Average Adjusted Net Mortgage Rate below the Weighted Average Adjusted Net Mortgage Rate of the Loan Group making the payment, then the payment will be treated by the REMIC 1 as a Realized Loss. Conversely, if the Loan Group of the Class C Interest that receives such payment has a Weighted Average Adjusted Net Mortgage Rate above the Weighted Average Adjusted Net Mortgage Rate of the Loan Group making the payment, then the payment will be treated by the REMIC 1 as a reimbursement for prior Realized Losses.

REMIC 2

The REMIC 2 Regular Interests will have the initial principal balance, Pass-Through Rates and corresponding Loan Groups as set forth in the following table:

REMIC 2 Interests	Initial Principal Balance	Pass-Through Rate	Corresponding Class of Certificates or Component

(1)

The Pass-Through Rate for the Class A-1 Certificates for the Interest Accrual Period related to each Distribution Date will equal the lesser of (x) LIBOR plus the related Pass-Through Margin and (y) the Net Rate Cap; provided that, so long as the Swap Contract remains in effect, the Net Rate Cap will not apply to the Pass-Through Rate of the Class A-1 Certificates. Solely for federal income tax purposes, the Pass-Through Rate for the Class A-1 Certificates will be calculated without reference to the foregoing proviso and by calculating the Net Rate Cap without reference to any Swap Termination Payments. The Pass-Through Rate for this Class of Certificates for the Interest Accrual Period related to the first Distribution Date is 5.5650% per annum.

(2)

The Pass-Through Rate for the Class 1-A-2 Certificates for the Interest Accrual Period related to each Distribution Date will equal the Weighted Average Adjusted Net Mortgage Rate of the Group 1 Mortgage Loans for that Distribution Date. The Pass-Through Rate for the Class 1-A-2 Certificates for the Interest Accrual Period related to the first Distribution Date is 6.4993% per annum.

(3)

The Pass-Through Rate for the Class 2-A-2 Certificates for the Interest Accrual Period related to each Distribution Date will equal the Weighted Average Adjusted Net Mortgage Rate of the Group 2 Mortgage Loans for that Distribution Date. The Pass-Through Rate for the Class 2-A-2 Certificates for the Interest Accrual Period related to the first Distribution Date is 6.5645% per annum.

(4)

The Pass-Through Rate for the Class 3-A-2 Certificates for the Interest Accrual Period related to each Distribution Date will equal the Weighted Average Adjusted Net Mortgage Rate of the Group 3 Mortgage Loans for that Distribution Date. The Pass-Through Rate for the Class 3-A-2 Certificates for the Interest Accrual Period related to the first Distribution Date is 6.2236% per annum.

(5)

The Pass-Through Rate for each Class of Subordinated Certificates for each Interest Accrual Period for any Distribution Date will be a per annum rate equal to the Subordinate Pass-Through Rate. The Pass-Through Rate for the Subordinated Certificates for the Interest Accrual Period related to the first Distribution Date is 6.3747% per annum. For federal income tax purposes, the Pass-Through Rate for each Class of Subordinated Certificates will be the Calculation Rate.

(6)	The Class P-1 Certificates will not be entitled to any interest, but will be entitled to 100% of any Hard Prepayment Charges collected on the Mortgage Loans. The Class P-1 Certificates are issuable as a single certificate.

(7)	The Class P-2 Certificates will not be entitled to any interest, but will be entitled to 100% of any Soft Prepayment Charges paid on the Mortgage Loans. The Class P-2 Certificates are issuable as a single certificate.

(8)

The Class L Certificates will not bear interest but will be entitled to 100% of any Late Payment Fees collected on the Mortgage Loans. For federal income tax purposes, the Trustee will treat Late Payment Fees as beneficially owned by the Holder of the Class L Certificates and shall treat such portion of the Trust Fund as an interest in a “trust” within the meaning of Treasury regulations section 301.7701-4(a) (the “Grantor Trust”). The Class L Certificates are issuable as a single certificate.

The Master REMIC will issue an uncertificated Class IO Interest that will be retained by Deutsche Bank Securities Inc. The Class IO Interest will: (i) be designated a regular interest in the Master REMIC, (ii) have a notional balance on each Distribution Date equal to the sum of the principal balances of the Class 2-1-A-1, Class 2-2-A-1 and Class 2-3-A-1 Interests for such Distribution Date and (iii) have a Pass-Through Rate, for the Interest Accrual Period for any Distribution Date, equal to the excess, if any, of the Net Rate Cap in respect of the Class A-1 Certificates, excluding for purposes of this calculation any reference to Swap Termination Payments, over the Pass-Through Rate for the Class A-1 Certificates, as adjusted for federal income tax purposes in Note (1) to the “Master REMIC” chart, for such Interest Accrual Period.

The foregoing REMIC structure is intended to cause all of the cash from the Mortgage Loans to flow through to the Master REMIC as cash flow on a REMIC regular interest, without creating any shortfall—actual or potential (other than for credit losses) to any REMIC regular interest.

For any purpose for which the Pass-Through Rates is calculated, the interest rate on the Mortgage Loans shall be appropriately adjusted to account for the difference between the monthly day count convention of the Mortgage Loans and the monthly day count convention of the regular interests issued by each of the REMICs. For purposes of calculating the Pass-Through Rates for each of the interests issued by REMIC 1 and the Master REMIC such rates shall be adjusted to equal a monthly day count convention based on a 30 day month for each Due Period and a 360-day year so that the Mortgage Loans and all regular interests will be using the same monthly day count convention.

Section 1.02 Rules of Construction.

Except as otherwise expressly provided in this Agreement or unless the context clearly requires otherwise

(a) References to designated articles, sections, subsections, exhibits, and other subdivisions of this Agreement, such as “Section 6.12 (a),” refer to the designated article, section, subsection, exhibit, or other subdivision of this Agreement as a whole and to all subdivisions of the designated article, section, subsection, exhibit, or other subdivision. The words “herein,” “hereof,” “hereto,” “hereunder,” and other words of similar import refer to this Agreement as a whole and not to any particular article, section, exhibit, or other subdivision of this Agreement.

(b) Any term that relates to a document or a statute, rule, or regulation includes any amendments, modifications, supplements, or any other changes that may have occurred since the document, statute, rule, or regulation came into being, including changes that occur after the date of this Agreement.

(c) Any party may execute any of the requirements under this Agreement either directly or through others, and the right to cause something to be done rather than doing it directly shall be implicit in every requirement under this Agreement. Unless a provision is restricted as to time or limited as to frequency, all provisions under this Agreement are implicitly available and things may happen from time to time.

(d) The term “including” and all its variations mean “including but not limited to.” Except when used in conjunction with the word “either,” the word “or” is always used inclusively (for example, the phrase “A or B” means “A or B or both,” not “either A or B but not both”).

(e) A reference to “a [thing]” or “any [of a thing]” does not imply the existence or occurrence of the thing referred to even though not followed by “if any,” and “any [of a thing]” is any of it. A reference to the plural of anything as to which there could be either one or more than one does not imply the existence of more than one (for instance, the phrase “the obligors on a note” means “the obligor or obligors on a note”). “Until [something occurs]” does not imply that it must occur, and will not be modified by the word “unless.” The word “due” and the word “payable” are each used in the sense that the stated time for payment has passed. The word “accrued” is used in its accounting sense, i.e., an amount paid is no longer accrued. In the calculation of amounts of things, differences and sums may generally result in negative numbers, but when the calculation of the excess of one thing over another results in zero

or a negative number, the calculation is disregarded and an “excess” does not exist. Portions of things may be expressed as fractions or percentages interchangeably.

(f) All accounting terms used in an accounting context and not otherwise defined, and accounting terms partly defined in this Agreement, to the extent not completely defined, shall be construed in accordance with generally accepted accounting principles. To the extent that the definitions of accounting terms in this Agreement are inconsistent with their meanings under generally accepted accounting principles, the definitions contained in this Agreement shall control. Capitalized terms used in this Agreement without definition that are defined in the Uniform Commercial Code are used in this Agreement as defined in the Uniform Commercial Code.

(g) In the computation of a period of time from a specified date to a later specified date or an open-ended period, the words “from” and “beginning” mean “from and including,” the word “after” means “from but excluding,” the words “to” and “until” mean “to but excluding,” and the word “through” means “to and including.” Likewise, in setting deadlines or other periods, “by” means “by.” The words “preceding,” “following,” and words of similar import, mean immediately preceding or following. References to a month or a year refer to calendar months and calendar years.

(h) Any reference to the enforceability of any agreement against a party means that it is enforceable, subject as to enforcement against the party, to applicable bankruptcy, insolvency, reorganization, and other similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles.

(C)	the executed Proprietary Lease;

(D)	the executed Recognition Agreement;

(E)	the executed UCC-1 financing statement that has been filed in all places required to perfect the Seller’s interest in the Co-op Shares and the Proprietary Lease with evidence of recording on it; and

(F)	executed UCC-3 financing statements or other appropriate UCC financing statements required by state law, evidencing a complete and unbroken line from the mortgagee to the Trustee with evidence of recording thereon (or in a form suitable for recordation).

In addition, in connection with the assignment of any MERS Mortgage Loan, the Seller agrees that it will cause, at the Seller’s expense, the MERS® System to indicate that the Mortgage Loans sold by the Seller to the Depositor have been assigned by the Seller to the Trustee in accordance with this Agreement for the benefit of the Certificateholders by including (or deleting, in the case of Mortgage Loans that are repurchased in accordance with this Agreement) in such computer files the information required by the MERS® System to identify the series of the Certificates issued in connection with such Mortgage Loans. The Seller further agrees that it will not, and will not permit the Servicer to, and the Servicer agrees that it will not, alter the information referenced in this paragraph with respect to any Mortgage Loan sold by the Seller to the Depositor during the term of this Agreement unless and until such Mortgage Loan is repurchased in accordance with the terms of this Agreement.

In the event that in connection with any Mortgage Loan that is not a MERS Mortgage Loan the Depositor cannot deliver (a) the original recorded Mortgage, (b) all interim recorded assignments or (c) the lender’s title policy (together with all riders thereto) satisfying the requirements of clause (ii), (iii) or (v) above, respectively, concurrently with the execution and delivery of this Agreement because such document or documents have not been returned from the applicable public recording office in the case of clause (ii) or (iii) above, or because the title policy has not been delivered to either the Servicer or the Depositor by the applicable title insurer in the case of clause (v) above, then the Depositor shall promptly deliver to the Trustee, in the case of clause (ii) or (iii) above, the original Mortgage or the interim assignment, as the case may be, with evidence of recording indicated on when it is received from the public recording office, or a copy of it, certified, if appropriate, by the relevant recording office and in the case of clause (v) above, the original or a copy of a written commitment or interim binder or preliminary report of title issued by the title insurance or escrow company, with the original or duplicate copy thereof to be delivered to the Trustee upon receipt thereof. The delivery of the original Mortgage Loan and each interim assignment or a copy of them, certified, if appropriate, by the relevant recording office, shall not be made later than one year following the Closing Date, or, in the case of clause (v) above, later than 120 days following the Closing Date. If the Depositor is unable to deliver each Mortgage by that date and each interim assignment because any documents have not been returned by the appropriate recording office, or, in the case of each interim assignment, because the related Mortgage has not been returned by the appropriate recording office, the Depositor shall deliver the documents to the Trustee as promptly as possible upon their receipt and, in any event, within 720 days following the Closing Date.

The Depositor shall forward to the Trustee (a) from time to time additional original documents evidencing an assumption or modification of a Mortgage Loan and (b) any other documents required to be delivered by the Depositor or the Servicer to the Trustee. If the original Mortgage is not delivered and in connection with the payment in full of the related Mortgage Loan the public recording office requires the presentation of a “lost instruments affidavit and indemnity” or any equivalent document, because only a copy of the Mortgage can be delivered with the instrument of satisfaction or reconveyance, the Servicer shall execute and deliver the required document to the public recording office. If a public recording office retains the original recorded Mortgage or if a Mortgage is lost after recordation in a public recording office, the Seller shall deliver to the Trustee a copy of the Mortgage certified by the public recording office to be a true and complete copy of the original recorded Mortgage.

As promptly as practicable after any transfer of a Mortgage Loan under this Agreement, and in any event within thirty days after the transfer, the Trustee shall (i) affix the Trustee’s name to each assignment of Mortgage, as its assignee, and (ii) cause to be delivered for recording in the appropriate public office for real property records the assignments of the Mortgages to the Trustee, except that, if the Trustee has not received the information required to deliver any assignment of a Mortgage for recording, the Trustee shall deliver it as soon as practicable after receipt of the needed information and in any event within thirty days.

If any Mortgage Loans have been prepaid in full as of the Closing Date, the Depositor, in lieu of delivering the above documents to the Trustee, will deposit in the Certificate Account the portion of the prepayment that is required to be deposited in the Certificate Account pursuant to Section 3.06.

Notwithstanding anything to the contrary in this Agreement, within five Business Days after the Closing Date, the Seller shall either

(x) deliver to the Trustee the Mortgage File as required pursuant to this Section 2.01 for each Delay Delivery Mortgage Loan or

(y) (A) repurchase the Delay Delivery Mortgage Loan or (B) substitute the Substitute Mortgage Loan for a Delay Delivery Mortgage Loan, which repurchase or substitution shall be accomplished in the manner and subject to the conditions in Section 2.03 (treating each such Delay Delivery Mortgage Loan as a Deleted Mortgage Loan for purposes of such Section 2.03);

provided, however, that if the Seller fails to deliver a Mortgage File for any Delay Delivery Mortgage Loan within the period specified herein, the Seller shall use its best reasonable efforts to effect a substitution, rather than a repurchase of, such Deleted Mortgage Loan and provided further that the cure period provided for in Section 2.02 or in Section 2.03 shall not apply to the initial delivery of the Mortgage File for such Delay Delivery Mortgage Loan, but rather the Seller shall have five (5) Business Days to cure such failure to deliver. At the end of such period, the Trustee shall send a Delay Delivery Certification for the Delay Delivery Mortgage Loans delivered during such period in accordance with the provisions of Section 2.02.

(d) Notwithstanding the foregoing, however, the assignments of Mortgage shall not be required to be submitted for recording (except with respect to any Mortgage Loan secured by Mortgaged Property located in Maryland) unless such failure to record would, as certified to the Trustee in writing by the Servicer, result in a withdrawal or a downgrading by any Rating Agency of the rating on any Class of Certificates; provided, however, that each assignment of Mortgage shall be submitted for recording by the Seller (at the direction of the Servicer) in the manner described above, at no expense to the Trust Fund or the Trustee, upon the earliest to occur of: (i) reasonable direction by the Holders of Certificates entitled to at least 25% of the Voting Rights, (ii) the occurrence of a bankruptcy, insolvency or foreclosure relating to the Seller, (iii) the occurrence of a servicing transfer as described in Section 7.02 and (iv) if the Seller is not the Servicer and with respect to any one assignment or Mortgage, the occurrence of a bankruptcy, insolvency or foreclosure relating to the Mortgagor under the related Mortgage. Notwithstanding the foregoing, if the Seller is unable to pay the cost of recording the assignments of Mortgage, such expense shall be paid by the Trustee and shall be reimbursable out of the Distribution Account.

(e) The Seller agrees to treat the transfer of the Mortgage Loans to the Depositor as a sale for all tax, accounting, and regulatory purposes.

(f) The Trust Fund does not intend to acquire or hold any Mortgage Loan that would violate the representations made by the Seller set forth in clause (27) of Schedule III.

Section 2.02 Acceptance by the Trustee of the Mortgage Loans.

The Trustee acknowledges receipt of the documents identified in the Initial Certification in the form of Exhibit G-1, and declares that it holds and will hold such documents and the other documents delivered to it constituting the Mortgage Files for the Mortgage Loans, and that it holds or will hold such other assets as are included in the Trust Fund, in trust for the exclusive use and benefit of all present and future Certificateholders.

The Trustee acknowledges that it will maintain possession of the related Mortgage Notes in the State of California, unless otherwise permitted by the Rating Agencies. The Trustee agrees to execute and deliver on the Closing Date to the Depositor, the Servicer and the Seller an Initial Certification in the form of Exhibit G-1. Based on its review and examination, and only as to the documents identified in such Initial Certification, the Trustee acknowledges that such documents appear regular on their face and relate to such Mortgage Loans. The Trustee shall be under no duty or obligation to inspect, review or examine said documents, instruments, certificates or other papers to determine that the same are genuine,

enforceable or appropriate for the represented purpose or that they have actually been recorded in the real estate records or that they are other than what they purport to be on their face.

By the thirtieth day after the Closing Date (or if that day is not a Business Day, the succeeding Business Day), the Trustee shall deliver to the Depositor, the Servicer, and the Seller a Delay Delivery Certification with respect to the Mortgage Loans substantially in the form of Exhibit G-2, with any applicable exceptions noted thereon.

By the ninetieth day after the Closing Date (or if that day is not a Business Day, the succeeding Business Day), the Trustee shall deliver to the Depositor, the Servicer and the Seller a Final Certification with respect to the Mortgage Loans in the form of Exhibit H, with any applicable exceptions noted thereon.

If, in the course of its review, the Trustee finds any document constituting a part of a Mortgage File that does not meet the requirements of Section 2.01, the Trustee shall list such as an exception in the Final Certification. The Trustee shall not make any determination as to whether (i) any endorsement is sufficient to transfer all interest of the party so endorsing, as noteholder or assignee thereof, in that Mortgage Note or (ii) any assignment is in recordable form or is sufficient to effect the assignment of and transfer to the assignee thereof under the mortgage to which the assignment relates. The Seller shall promptly correct any defect that materially and adversely affects the interests of the Certificateholders within 90 days from the date it was so notified of the defect and, if the Seller does not correct the defect within that period, the Seller shall either (a) substitute for the related Mortgage Loan a Substitute Mortgage Loan, which substitution shall be accomplished in the pursuant Section 2.03, or (b) purchase the Mortgage Loan at its Purchase Price from the Trustee within 90 days from the date the Seller was notified of the defect in writing.

Any substitution pursuant to clause (a) above or purchase pursuant to clause (b) above shall not be effected before the delivery to the Trustee of the Opinion of Counsel, if required by Section 2.05, and any substitution pursuant to clause (a) above shall not be effected before the additional delivery to the Trustee of a Request for Release substantially in the form of Exhibit N. No substitution is permitted to be made in any calendar month after the Determination Date for the month.

If a substitution or purchase of a Mortgage Loan pursuant to this provision is required because of a delay in delivery of any documents by the appropriate recording office, or there is a dispute between either the Servicer or the Seller and the Trustee over the location or status of the recorded document, then the substitution or purchase shall occur within 720 days from the Closing Date. In no other case may a substitution or purchase occur more than 540 days from the Closing Date.

The Purchase Price for any Mortgage Loan shall be deposited by the Seller in the Certificate Account by the Distribution Account Deposit Date for the Distribution Date in the month following the month of repurchase and, upon receipt of the deposit and certification with respect thereto in the form of Exhibit N, the Trustee shall release the related Mortgage File to the Seller and shall execute and deliver at the Seller’s request any instruments of transfer or assignment prepared by the Seller, in each case without recourse, necessary to vest in the Seller, or a designee, the Trustee’s interest in any Mortgage Loan released pursuant hereto.

If pursuant to the foregoing provisions the Seller repurchases a Mortgage Loan that is a MERS Mortgage Loan, the Servicer shall either (i) cause MERS to execute and deliver an assignment of the Mortgage in recordable form to transfer the Mortgage from MERS to the Seller and shall cause such Mortgage to be removed from registration on the MERS® System in accordance with MERS’ rules and

regulations or (ii) cause MERS to designate on the MERS® System the Seller as the beneficial holder of such Mortgage Loan.

The Trustee shall retain possession and custody of each Mortgage File in accordance with and subject to the terms and conditions set forth herein. The Servicer shall promptly deliver to the Trustee, upon the execution or receipt thereof, the originals of any other documents or instruments constituting the Mortgage File that come into the possession of the Servicer from time to time.

The obligation of the Seller to substitute for or to purchase any Mortgage Loan that does not meet the requirements of Section 2.01 shall constitute the sole remedy respecting the defect available to the Trustee, the Depositor, and any Certificateholder against the Seller.

Section 2.03 Representations, Warranties, and Covenants of the Seller and the Servicer.

(a) IndyMac, in its capacities as Seller and Servicer, makes the representations and warranties in Schedule II, and by this reference incorporated in this Agreement, to the Depositor and the Trustee, as of the Closing Date.

(b) The Seller, in its capacity as Seller, makes the representations and warranties in Schedule III, and by this reference incorporated in this Agreement, to the Depositor and the Trustee, as of the Closing Date, or if so specified in Schedule III, as of the Cut-off Date.

(c) Upon discovery by any of the parties hereto of a breach of a representation or warranty made pursuant to Section 2.03(b) that materially and adversely affects the interests of the Certificateholders in any Mortgage Loan, the party discovering such breach shall give prompt notice thereof to the other parties. Any breach of representations and warranties under clauses (27) and (32) of Schedule III shall be deemed to materially and adversely affect the interests of the Certificateholders in the affected Mortgage Loans. The Seller covenants that within 90 days of the earlier of its discovery or its receipt of written notice from any party of a breach of any representation or warranty made pursuant to Section 2.03(b) which materially and adversely affects the interests of the Certificateholders in any Mortgage Loan, it shall cure such breach in all material respects, and if such breach is not so cured, shall, (i) if the 90-day period expires before the second anniversary of the Closing Date, remove the Mortgage Loan (a “Deleted Mortgage Loan”) from the Trust Fund and substitute in its place a Substitute Mortgage Loan, in accordance with this Section 2.03; or (ii) repurchase the affected Mortgage Loan or Mortgage Loans from the Trustee at the Purchase Price in the manner set forth below. Any substitution pursuant to (i) above shall not be effected before the delivery to the Trustee of the Opinion of Counsel, if required by Section 2.05, and a Request for Release substantially in the form of Exhibit N, and the Mortgage File for any Substitute Mortgage Loan. The Seller shall promptly reimburse the Servicer and the Trustee for any expenses reasonably incurred by the Servicer or the Trustee in respect of enforcing the remedies for the breach.

With respect to any Substitute Mortgage Loan or Loans, the Seller shall deliver to the Trustee for the benefit of the Certificateholders the Mortgage Note, the Mortgage, the related assignment of the Mortgage, and such other documents and agreements as are required by Section 2.01, with the Mortgage Note endorsed and the Mortgage assigned as required by Section 2.01. No substitution is permitted to be made in any calendar month after the Determination Date for such month. Scheduled Payments due with respect to Substitute Mortgage Loans in the month of substitution shall not be part of the Trust Fund and will be retained by the Seller on the next succeeding Distribution Date. For the month of substitution, distributions to Certificateholders will include the monthly payment due on any Deleted Mortgage Loan for such month and thereafter the Seller shall be entitled to retain all amounts received in respect of such Deleted Mortgage Loan.

The Servicer shall amend the Mortgage Loan Schedule for the benefit of the Certificateholders to reflect the removal of the Deleted Mortgage Loan and the substitution of the Substitute Mortgage Loans and the Servicer shall deliver the amended Mortgage Loan Schedule to the Trustee. Upon the substitution, the Substitute Mortgage Loans shall be subject to this Agreement in all respects, and the Seller shall be deemed to have made with respect to the Substitute Mortgage Loans, as of the date of substitution, the representations and warranties made pursuant to Section 2.03(b) with respect to the Mortgage Loan. Upon any substitution and the deposit to the Certificate Account of the amount required to be deposited therein in connection with the substitution as described in the following paragraph, the Trustee shall release the Mortgage File held for the benefit of the Certificateholders relating to the Deleted Mortgage Loan to the Seller and shall execute and deliver at the Seller’s direction such instruments of transfer or assignment prepared by the Seller, in each case without recourse, as shall be necessary to vest title in the Seller, or its designee, the Trustee’s interest in any Deleted Mortgage Loan substituted for pursuant to this Section 2.03.

For any month in which the Seller substitutes one or more Substitute Mortgage Loans for one or more Deleted Mortgage Loans, the Servicer will determine the amount (if any) by which the aggregate principal balance of all such Substitute Mortgage Loans as of the date of substitution is less than the aggregate Stated Principal Balance of all such Deleted Mortgage Loans (after application of the scheduled principal portion of the monthly payments due in the month of substitution). The amount of such shortage (the “Substitution Adjustment Amount”) plus, if the Seller is not the Servicer, an amount equal to the aggregate of any unreimbursed Advances and Servicer Advances with respect to such Deleted Mortgage Loans shall be deposited into the Certificate Account by the Seller by the Distribution Account Deposit Date for the Distribution Date in the month succeeding the calendar month during which the related Mortgage Loan became required to be purchased or replaced hereunder. If the Seller repurchases a Mortgage Loan, the Purchase Price therefor shall be deposited in the Certificate Account pursuant to Section 3.06 by the Distribution Account Deposit Date for the Distribution Date in the month following the month during which the Seller became obligated hereunder to repurchase or replace the Mortgage Loan and upon such deposit of the Purchase Price and receipt of a Request for Release in the form of Exhibit N, the Trustee shall release the related Mortgage File held for the benefit of the Certificateholders to such Person, and the Trustee shall execute and deliver at such Person’s direction such instruments of transfer or assignment prepared by such Person, in each case without recourse, as shall be necessary to transfer title from the Trustee. The obligation under this Agreement of any Person to cure, repurchase, or replace any Mortgage Loan as to which a breach has occurred and is continuing shall constitute the sole remedy against the Person respecting the breach available to Certificateholders, the Depositor, or the Trustee on their behalf.

The representations and warranties made pursuant to this Section 2.03 shall survive delivery of the respective Mortgage Files to the Trustee for the benefit of the Certificateholders and shall not be waived by the Depositor.

The Seller assigns to the Depositor and the Depositor assigns to the Trustee all rights the Seller might have under contracts with third parties relating to early payment defaults on the Mortgage Loans (“EPD Rights”) and the Servicer assumes any related duties as part of its servicing obligations. Consistent with the Servicing Standard, the Servicer shall attempt to enforce the EPD Rights. If the Servicer’s enforcement of the EPD Rights obligates the Servicer to sell a Mortgage Loan to a third party, the Servicer shall repurchase the Mortgage Loan at the Purchase Price and sell the Mortgage Loan to the third party, provided however, in no case shall the Servicer be obligated to repurchase a Mortgage Loan on account of EPD Rights unless and until the Servicer shall have previously received repurchase payment from a third party. The Servicer shall deposit into the Certificate Account all amounts received in connection with the enforcement of EPD Rights, not exceeding the Purchase Price, with respect to any Mortgage Loan. Any amounts received by the Servicer with respect a Mortgage Loan in excess of the

Purchase Price shall be retained by the Servicer as additional servicing compensation. The Trustee, upon receipt of certification from the Servicer of the deposit of the Purchase Price in connection with a repurchase of a Mortgage Loan and a Request for File Release from the Servicer, shall release or cause to be released to the purchaser of such Mortgage Loan the related Mortgage File and shall execute and deliver such instruments of transfer or assignment prepared by the purchaser of such Mortgage Loan, in each case without recourse, as shall be necessary to vest in the purchaser of such Mortgage Loan any Mortgage Loan released pursuant hereto and the purchaser of such Mortgage Loan shall succeed to all the Trustee’s right, title and interest in and to such Mortgage Loan and all security and documents related thereto. Such assignment shall be an assignment outright and not for security. The purchaser of such Mortgage Loan shall thereupon own such Mortgage Loan, and all security and documents, free of any further obligation to the Trustee or the Certificateholders with respect thereto.

Section 2.04 Representations and Warranties of the Depositor as to the Mortgage Loans.

The Depositor represents and warrants to the Trustee with respect to each Mortgage Loan as of the date of this Agreement or such other date set forth in this Agreement that as of the Closing Date, and following the transfer of the Mortgage Loans to it by the Seller, the Depositor had good title to the Mortgage Loans and the Mortgage Notes were subject to no offsets, defenses, or counterclaims.

The representations and warranties in this Section 2.04 shall survive delivery of the Mortgage Files to the Trustee. Upon discovery by the Depositor or the Trustee of any breach of any of the representations and warranties in this Section that materially and adversely affects the interest of the Certificateholders, the party discovering the breach shall give prompt written notice to the others and to each Rating Agency.

Section 2.05 Delivery of Opinion of Counsel in Connection with Substitutions.

(a) Notwithstanding any contrary provision of this Agreement, no substitution pursuant to Section 2.02 or 2.03 shall be made more than 90 days after the Closing Date unless the Seller delivers to the Trustee an Opinion of Counsel, which Opinion of Counsel shall not be at the expense of either the Trustee or the Trust Fund, addressed to the Trustee, to the effect that such substitution will not (i) result in the imposition of the tax on “prohibited transactions” on the Trust Fund or contributions after the Startup Date, as defined in sections 860F(a)(2) and 860G(d) of the Code, respectively or (ii) cause any REMIC created under this Agreement to fail to qualify as a REMIC at any time that any Certificates are outstanding.

(b) Upon discovery by the Depositor, the Seller, the Servicer or the Trustee that any Mortgage Loan does not constitute a “qualified mortgage” within the meaning of section 860G(a)(3) of the Code, the party discovering such fact shall promptly (and in any event within five Business Days of discovery) give written notice thereof to the other parties. In connection therewith, the Trustee shall require the Seller, at the Seller’s option, to either (i) substitute, if the conditions in Section 2.03(c) with respect to substitutions are satisfied, a Substitute Mortgage Loan for the affected Mortgage Loan, or (ii) repurchase the affected Mortgage Loan within 90 days of such discovery in the same manner as it would a Mortgage Loan for a breach of representation or warranty made pursuant to Section 2.03. The Trustee shall reconvey to the Seller the Mortgage Loan to be released pursuant hereto in the same manner, and on the same terms and conditions, as it would a Mortgage Loan repurchased for breach of a representation or warranty contained in Section 2.03.

Section 2.06 Execution and Delivery of Certificates.

The Trustee acknowledges the transfer and assignment to it of the Trust Fund and, concurrently with such transfer and assignment, has executed and delivered to or upon the order of the Depositor, the Certificates in authorized denominations evidencing directly or indirectly the entire ownership of the Trust Fund. The Trustee agrees to hold the Trust Fund and exercise the rights referred to above for the benefit of all present and future Holders of the Certificates.

Section 2.07 REMIC Matters.

The Preliminary Statement sets forth the designations and “latest possible maturity date” for federal income tax purposes of all interests created under this Agreement. The “Startup Day” for purposes of the REMIC Provisions shall be the Closing Date. Each REMIC’s fiscal year shall be the calendar year.

ARTICLE THREE

Administration and Servicing of Mortgage Loans

Section 3.01 Servicer to Service Mortgage Loans.

For and on behalf of the Certificateholders, the Servicer shall service and administer the Mortgage Loans in accordance with this Agreement and the Servicing Standard.

The Servicer shall not make or permit any modification, waiver, or amendment of any term of any Mortgage Loan that would cause any REMIC created under this Agreement to fail to qualify as a REMIC or result in the imposition of any tax under section 860F(a) or section 860G(d) of the Code.

Without limiting the generality of the foregoing, the Servicer, in its own name or in the name of the Depositor and the Trustee, is hereby authorized and empowered by the Depositor and the Trustee, when the Servicer believes it appropriate in its reasonable judgment, to execute and deliver, on behalf of the Trustee, the Depositor, the Certificateholders, or any of them, any instruments of satisfaction or cancellation, or of partial or full release or discharge, and all other comparable instruments, with respect to the Mortgage Loans, and with respect to the Mortgaged Properties held for the benefit of the Certificateholders. The Servicer shall prepare and deliver to the Depositor or the Trustee any documents requiring execution and delivery by either or both of them appropriate to enable the Servicer to service and administer the Mortgage Loans to the extent that the Servicer is not permitted to execute and deliver such documents pursuant to the preceding sentence. Upon receipt of the documents, the Depositor or the Trustee shall execute the documents and deliver them to the Servicer.

The Servicer further is authorized and empowered by the Trustee, on behalf of the Certificateholders and the Trustee, in its own name, when the Servicer believes it appropriate in its best judgment to register any Mortgage Loan on the MERS® System, or cause the removal from the registration of any Mortgage Loan on the MERS® System, to execute and deliver, on behalf of the Trustee and the Certificateholders or any of them, any and all instruments of assignment and other comparable instruments with respect to such assignment or re-recording of a Mortgage in the name of MERS, solely as nominee for the Trustee and its successors and assigns.

In accordance with and to the extent of the Servicing Standard, the Servicer shall advance funds necessary to effect the payment of taxes and assessments on the Mortgaged Properties, which advances shall be reimbursable in the first instance from related collections from the Mortgagors pursuant to Section 3.07, and further as provided in Section 3.09. Except in connection with a Loan Modification that results in a Capitalized Advance, the costs incurred by the Servicer in effecting the timely payments of taxes and assessments on the Mortgaged Properties and related insurance premiums shall not, for the purpose of calculating monthly distributions to the Certificateholders, be added to the Stated Principal Balances of the related Mortgage Loans, notwithstanding that the Mortgage Loans so permit.

Nothing in this Agreement to the contrary shall limit the Servicer from undertaking any legal action that it may deem appropriate with respect to the Mortgage Loans including, without limitation, any rights or causes of action arising out of the origination of the Mortgage Loans.

Section 3.02 [Reserved].

Section 3.03 Rights of the Depositor and the Trustee in Respect of the Servicer.

The Depositor may, but is not obligated to, enforce the obligations of the Servicer under this Agreement and may, but is not obligated to, perform, or cause a designee to perform, any defaulted obligation of the Servicer under this Agreement and in connection with any such defaulted obligation to exercise the related rights of the Servicer under this Agreement; provided that the Servicer shall not be relieved of any of its obligations under this Agreement by virtue of such performance by the Depositor or its designee. Neither the Trustee nor the Depositor shall have any responsibility or liability for any action or failure to act by the Servicer nor shall the Trustee or the Depositor be obligated to supervise the performance of the Servicer under this Agreement or otherwise.

Section 3.04 [Reserved].

Section 3.05 Trustee to Act as Servicer.

If the Servicer for any reason is no longer the Servicer under this Agreement (including because of the occurrence or existence of an Event of Default or termination by the Depositor), the Trustee or its successor shall assume all of the rights and obligations of the Servicer under this Agreement arising thereafter (except that the Trustee shall not be

(i) liable for losses of the Servicer pursuant to Section 3.10 or any acts or omissions of the predecessor Servicer hereunder,

(ii) obligated to make Advances if it is prohibited from doing so by applicable law,

(iii) obligated to effectuate repurchases or substitutions of Mortgage Loans hereunder, including repurchases or substitutions pursuant to Section 2.02 or 2.03,

(iv) responsible for expenses of the Servicer pursuant to Section 2.03, or

(v) deemed to have made any representations and warranties of the Servicer hereunder). Any assumption shall be subject to Section 7.02.

Notwithstanding anything else in this Agreement to the contrary, in no event shall the Trustee be liable for any servicing fee or for any differential in the amount of the Servicing Fee paid under this Agreement and the amount necessary to induce any successor Servicer to act as successor Servicer under this Agreement and the transactions provided for in this Agreement.

Section 3.06 Collection of Mortgage Loan Payments; Certificate Account; Distribution Account; Swap Account; Collateral Account.

(a) In accordance with and to the extent of the Servicing Standard, the Servicer shall make reasonable efforts in accordance with the customary and usual standards of practice of prudent mortgage servicers to collect all payments called for under the Mortgage Loans to the extent the procedures are consistent with this Agreement and any related Required Insurance Policy. Consistent with the foregoing, the Servicer may in its discretion (i) subject to Section 3.21, waive any Late Payment Fee or, subject to Section 3.20, waive any Prepayment Charge in connection with the prepayment of a Mortgage Loan and (ii) extend the due dates for payments due on a Delinquent Mortgage Loan for a period not greater than 125 days. In connection with a Mortgage Loan that is in default, or with respect to which default is

reasonably foreseeable, the Servicer may, consistent with the Servicing Standard, waive, modify or vary any term of that Mortgage Loan (including modifications that change the Mortgage Rate, forgive the payment of principal or interest or extend the final maturity date of that Mortgage Loan ), accept payment from the related Mortgagor of an amount less than the Stated Principal Balance in final satisfaction of that Mortgage Loan, or consent to the postponement of strict compliance with any such term or otherwise grant indulgence to any Mortgagor if in the Servicer’s determination such waiver, modification, postponement or indulgence (such a waiver, modification, postponement or indulgence, a “Preemptive Loan Modification”) is not materially adverse to the interests of the Certificateholders (taking into account any estimated loss that might result absent such action) and is expected to minimize the loss on such Mortgage Loan; provided, however, the Servicer shall not initiate new lending to such Mortgagor through the Trust and cannot extend the maturity of any Mortgage Loan past the date on which the final payment is due on the latest maturing Mortgage Loan as of the Cut-off Date. The Servicer shall not be required to institute or join in litigation with respect to collection of any payment (whether under a Mortgage, Mortgage Note, or otherwise or against any public or governmental authority with respect to a taking or condemnation) if it reasonably believes that enforcing the provision of the Mortgage or other instrument pursuant to which the payment is required is prohibited by applicable law. The Servicer shall not have the discretion to sell any Delinquent or defaulted Mortgage Loan.

(b) [Reserved].

(d) The Servicer shall establish and maintain a Certificate Account into which the Servicer shall deposit within two Business Days of receipt or as otherwise specified in this Agreement, the following payments and collections received by it in respect of Mortgage Loans after the Cut-off Date (other than in respect of principal and interest due on the Mortgage Loans by the Cut-off Date) and the following amounts required to be deposited hereunder:

(i) all payments on account of principal on the Mortgage Loans, including Principal Prepayments;

(ii) all payments on account of interest on the Mortgage Loans, net of the Prepayment Interest Excess and of the Servicing Fee;

(iii) all Insurance Proceeds, Subsequent Recoveries and Liquidation Proceeds, other than proceeds to be applied to the restoration or repair of the Mortgaged Property or released to the Mortgagor in accordance with the Servicer’s normal servicing procedures;

(iv) any amount required to be deposited by the Servicer pursuant to Section 3.06(f) in connection with any losses on Permitted Investments;

(v) any amounts required to be deposited by the Servicer pursuant to Sections 3.10 and 3.12;

(vi) all Purchase Prices from the Servicer or Seller and all Substitution Adjustment Amounts;

(vii) all Advances made by the Servicer pursuant to Section 4.01;

(viii) any other amounts required to be deposited under this Agreement;

(ix) all Late Payment Fees collected by the Servicer; and

(x) all Prepayment Charges collected and amounts payable by the Servicer for the waiver of such amounts.

In addition, with respect to any Mortgage Loan that is subject to a buydown agreement, on each Due Date for the Mortgage Loan, in addition to the monthly payment remitted by the Mortgagor, the Servicer shall cause funds to be deposited into the Certificate Account in an amount required to cause an amount of interest to be paid with respect to the Mortgage Loan equal to the amount of interest that has accrued on the Mortgage Loan from the preceding Due Date at the Mortgage Rate net of the Servicing Fee Rate on that date.

The foregoing requirements for remittance by the Servicer to the Certificate Account shall be exclusive, it being understood and agreed that, without limiting the generality of the foregoing, payments in the nature of assumption fees, if collected, need not be remitted by the Servicer. If the Servicer remits any amount not required to be remitted, it may at any time withdraw that amount from the Certificate Account, any provision in this Agreement to the contrary notwithstanding. The withdrawal or direction may be accomplished by delivering written notice of it to the Trustee or any other institution maintaining the Certificate Account that describes the amounts deposited in error in the Certificate Account. The Servicer shall maintain adequate records with respect to all withdrawals made pursuant to this Section 3.06. All funds deposited in the Certificate Account shall be held in trust for the Certificateholders until withdrawn in accordance with Section 3.09.

(e) The Trustee shall establish and maintain the Distribution Account on behalf of the Certificateholders, which shall be a segregated, non-interest bearing account. The Trustee shall, promptly upon receipt, deposit in the Distribution Account and retain in the Distribution Account the following:

(i) the aggregate amount remitted by the Servicer to the Trustee pursuant to Section 3.09(a);

(ii) any amount deposited by the Servicer pursuant to Section 3.06(f) in connection with any losses on Permitted Investments; and

(iii) any other amounts deposited under this Agreement that are required to be deposited in the Distribution Account.

If the Servicer remits any amount not required to be remitted, it may at any time direct the Trustee in writing to withdraw that amount from the Distribution Account, any provision in this Agreement to the contrary notwithstanding. The direction may be accomplished by delivering an Officer’s Certificate to the Trustee that describes the amounts deposited in error in the Distribution Account. All funds deposited in the Distribution Account shall be held by the Trustee in trust for the Certificateholders until disbursed in accordance with this Agreement or withdrawn in accordance with Section 3.09. In no event shall the Trustee incur liability for withdrawals from the Distribution Account at the direction of the Servicer.

(f) Each institution at which the Certificate Account is maintained shall invest the funds in such account as directed in writing by the Servicer in Permitted Investments, which shall mature not later than the second Business Day preceding the related Distribution Account Deposit Date (except that if the Permitted Investment is an obligation of the institution that maintains the account, then the Permitted Investment shall mature not later than the Business Day preceding the Distribution Account Deposit Date) and which shall not be sold or disposed of before its maturity. The funds in the Distribution Account shall

remain uninvested. All such Permitted Investments shall be made in the name of the Trustee, for the benefit of the Certificateholders. All income realized from any such investment of funds on deposit in the Certificate Account shall be for the benefit of the Servicer as servicing compensation and shall be remitted to it monthly as provided in this Agreement. The amount of any realized losses on Permitted Investments in the Certificate Account shall promptly be deposited by the Servicer in the Certificate Account. The Trustee shall not be liable for the amount of any loss incurred in respect of any investment or lack of investment of funds held in the Certificate Account and made in accordance with this Section 3.06.

(g) (i) On the Closing Date, the Supplemental Interest Trustee shall establish and maintain in its name, in trust for the benefit of the Holders of the LIBOR Certificates, the Swap Account. The Swap Account shall be a non-interest bearing Eligible Account, and funds on deposit in the account shall be held separate and apart from, and shall not be commingled with, any other moneys, including without limitation, other moneys held by the Trustee pursuant to this Agreement.

(ii) The Supplemental Interest Trustee shall deposit in the Swap Account all amounts received from the Swap Counterparty for any Distribution Date. If the Supplemental Interest Trustee deposits into the Swap Account any amount not required to be deposited in that account, it may at any time withdraw such amount from the Swap Account, any provision in this Agreement to the contrary notwithstanding. Funds in the Swap Account shall be held uninvested.

(iii) Funds on deposit in the Swap Account shall be distributed in the amounts and in the order described under Section 4.02(d).

(iv) On each Distribution Date, the Trustee shall make the deposits to the Swap Account pursuant to Section 4.02(a) and (b).

(h) (i) Upon the execution of an ISDA Credit Support Annex, the Supplemental Interest Trustee shall establish and maintain in its name, in trust for the benefit of the Holders of the LIBOR Certificates, the Collateral Account.

(ii) The Supplemental Interest Trustee shall deposit in the Collateral Account any collateral (whether in the form of cash, securities or any other eligible investments) pledged by the Swap Counterparty under the ISDA Credit Support Annex. If the Supplemental Interest Trustee deposits into the Collateral Account any amount not required to be deposited in that account, it may at any time withdraw such amount from the Collateral Account, any provision in this Agreement to the contrary notwithstanding. Funds in the Collateral Account shall be invested in permitted investments defined in the ISDA Credit Support Annex. The Supplemental Interest Trustee shall not be liable for any loss of investment of funds made pursuant to the ISDA Credit Support Annex.

(iii) Funds on deposit in the Collateral Account shall be applied in accordance with the terms of the related ISDA Credit Support Annex.

(i) The Servicer shall give notice to the Trustee, the Seller, each Rating Agency and the Depositor of any proposed change of the location of the Certificate Account not later than 30 days and not more than 45 days prior to any change of this Agreement. The Trustee shall give notice to the Servicer, the Seller, each Rating Agency and the Depositor of any proposed change of the location of the Distribution Account, Swap Account or Collateral Account not later than 30 days and not more than 45 days prior to any change of this Agreement.

(j) Upon a downgrade in the rating of an institution at which an Eligible Account is held below the required ratings set forth in the definition of Eligible Account, within 30 days of such downgrade, such account will be transferred to an account meeting the requirements of the definition of Eligible Account; provided, however, that this transfer requirement may be waived by the applicable Rating Agency.

Section 3.07 Collection of Taxes, Assessments and Similar Items; Escrow Accounts.

(a) To the extent required by the related Mortgage Note and not violative of current law, the Servicer shall establish and maintain one or more accounts (each, an “Escrow Account”) and deposit and retain therein all collections from the Mortgagors (or advances) for the payment of taxes, assessments, hazard insurance premiums or comparable items for the account of the Mortgagors. Nothing herein shall require the Servicer to compel a Mortgagor to establish an Escrow Account in violation of applicable law.

(b) Withdrawals of amounts so collected from the Escrow Accounts may be made only to effect timely payment of taxes, assessments, hazard insurance premiums, condominium or PUD association dues, or comparable items, to reimburse (without duplication) the Servicer out of related collections for any payments made pursuant to Section 3.01 (with respect to taxes and assessments and insurance premiums) and Section 3.10 (with respect to hazard insurance), to refund to any Mortgagors any sums determined to be overages, to pay interest, if required by law or the related Mortgage or Mortgage Note, to Mortgagors on balances in the Escrow Account or to clear and terminate the Escrow Account at the termination of this Agreement in accordance with Section 9.01. The Escrow Accounts shall not be a part of the Trust Fund.

(c) The Servicer shall advance any payments referred to in Section 3.07(a) that are not timely paid by the Mortgagors or advanced by the Servicer on the date when the tax, premium or other cost for which such payment is intended is due, but the Servicer shall be required so to advance only to the extent that such advances, in the good faith judgment of the Servicer, will be recoverable by the Servicer out of Insurance Proceeds, Liquidation Proceeds or otherwise.

Section 3.08 Access to Certain Documentation and Information Regarding the Mortgage Loans.

The Servicer shall afford the Depositor and the Trustee reasonable access to all records and documentation regarding the Mortgage Loans and all accounts, insurance information and other matters relating to this Agreement, such access being afforded without charge, but only upon reasonable request and during normal business hours at the office designated by the Servicer.

Upon reasonable advance notice in writing, the Servicer will provide to each Certificateholder or Certificate Owner that is a savings and loan association, bank, or insurance company certain reports and reasonable access to information and documentation regarding the Mortgage Loans sufficient to permit the Certificateholder or Certificate Owner to comply with applicable regulations of the OTS or other regulatory authorities with respect to investment in the Certificates. The Servicer shall be entitled to be reimbursed by each such Certificateholder or Certificate Owner for actual expenses incurred by the Servicer in providing the reports and access.

Section 3.09 Permitted Withdrawals from the Certificate Account, the Distribution Account and the Swap Account.

(a) The Servicer may (and, in the case of clause (ix) below, shall) from time to time make withdrawals from the Certificate Account for the following purposes:

(i) to pay to the Servicer (to the extent not previously retained) the servicing compensation to which it is entitled pursuant to Section 3.15, and to pay to the Servicer, as additional servicing compensation, earnings on or investment income with respect to funds in or credited to the Certificate Account;

(ii) to reimburse the Servicer or successor Servicer for the unreimbursed Advances made by it, such right of reimbursement pursuant to this subclause (ii) being limited to amounts received on the Mortgage Loans in respect of which the Advance was made;

(iii) to reimburse the Servicer or successor Servicer for any Nonrecoverable Advance previously made by it;

(iv) to reimburse the Servicer for Insured Expenses from the related Insurance Proceeds;

(v) to reimburse the Servicer for (a) unreimbursed Servicing Advances, the Servicer’s right to reimbursement pursuant to this clause (a) with respect to any Mortgage Loan being limited to amounts received on the Mortgage Loans that represent late recoveries of the payments for which the advances were made pursuant to Section 3.01 or Section 3.07, (b) unreimbursed Servicing Advances made in respect of a Mortgage Loan for which such Servicing Advances are not recoverable from the Mortgagor and (c) for unpaid Servicing Fees as provided in Section 3.12;

(vi) to pay to the purchaser, with respect to each Mortgage Loan or property acquired in respect of such Mortgage Loan that has been purchased pursuant to Section 2.02, 2.03, or 3.12, all amounts received thereon after the date of such purchase;

(vii) to reimburse the Seller, the Servicer, or the Depositor for expenses incurred by any of them and reimbursable pursuant to Section 6.03;

(viii) to withdraw any amount deposited in the Certificate Account and not required to be deposited in the Certificate Account;

(ix) by the Distribution Account Deposit Date, to withdraw (1) the Available Funds and the Trustee Fee for the Distribution Date, to the extent on deposit, and (2) the Prepayment Charges on deposit, and remit such amount to the Trustee for deposit in the Distribution Account; and

(x) to clear and terminate the Certificate Account upon termination of this Agreement pursuant to Section 9.01.

The Servicer shall keep and maintain separate accounting, on a Mortgage Loan by Mortgage Loan basis, to justify any withdrawal from the Certificate Account pursuant to subclauses (i), (ii), (iv), (v), and (vi). Before making any withdrawal from the Certificate Account pursuant to subclause (iii), the Servicer shall deliver to the Trustee an Officer’s Certificate of a Servicing Officer indicating the amount of any previous Advance determined by the Servicer to be a Nonrecoverable Advance and identifying the related Mortgage Loans and their respective portions of the Nonrecoverable Advance.

In addition to the amounts remitted to the Trustee by the Servicer from the Certificate Account, by the Distribution Account Deposit Date, the Servicer shall remit all Late Payment Fees assessable and not waived pursuant to Section 3.21(a) to the Trustee for deposit in the Distribution Account.

(b) The Trustee shall withdraw funds from the Distribution Account for distributions to Certificateholders in the manner specified in this Agreement (and to withhold from the amounts so withdrawn the amount of any taxes that it is authorized to withhold pursuant to the third paragraph of Section 8.11). In addition, the Trustee may from time to time make withdrawals from the Distribution Account for the following purposes:

(i) to pay to itself the Trustee Fee for the related Distribution Date;

(ii) to withdraw and return to the Servicer any amount deposited in the Distribution Account and not required to be deposited therein; and

(iii) to clear and terminate the Distribution Account upon termination of the Agreement pursuant to Section 9.01.

(c) On each Distribution Date, the Trustee shall make withdrawals from the Swap Account in the manner specified in Section 3.06 (and to withhold from the amounts so withdrawn the amount of any taxes that it is authorized to retain pursuant to the third paragraph of Section 8.11). In addition, the Trustee may from time to time make withdrawals from the Swap Account for the following purposes:

(i) to withdraw any amount deposited in the Swap Account and not required to be deposited therein; and

(ii) to clear and terminate the Swap Account upon the earlier of (x) the Swap Contract Termination Date and (y) the termination of this Agreement pursuant to Section 9.01.

Section 3.10 Maintenance of Hazard Insurance; Maintenance of Primary Insurance Policies.

(a) The Servicer shall maintain, for each Mortgage Loan, hazard insurance with extended coverage in an amount that is at least equal to the lesser of

(i) the maximum insurable value of the improvements securing the Mortgage Loan and

(ii) the greater of (y) the outstanding principal balance of the Mortgage Loan and (z) an amount such that the proceeds of the policy are sufficient to prevent the Mortgagor or the mortgagee from becoming a co-insurer.

Each policy of standard hazard insurance shall contain, or have an accompanying endorsement that contains, a standard mortgagee clause. Any amounts collected under the policies (other than the amounts to be applied to the restoration or repair of the related Mortgaged Property or amounts released to the Mortgagor in accordance with the Servicer’s normal servicing procedures) shall be deposited in the Certificate Account. Any cost incurred in maintaining any insurance shall not, for the purpose of calculating monthly distributions to the Certificateholders or remittances to the Trustee for their benefit, be added to the principal balance of the Mortgage Loan, notwithstanding that the Mortgage Loan so permits unless such costs are part of a Capitalized Advance. Such costs shall be recoverable by the Servicer out of late payments (other than Late Payment Fees) by the related Mortgagor or out of Liquidation Proceeds to the extent permitted by Section 3.09. No earthquake or other additional insurance is to be required of any Mortgagor or maintained on property acquired in respect of a Mortgage other than pursuant to any applicable laws and regulations in force that require additional insurance. If the Mortgaged Property is located at the time of origination of the Mortgage Loan in a federally designated special flood hazard area and the area is participating in the national flood insurance program,

the Servicer shall maintain flood insurance for the Mortgage Loan. The flood insurance shall be in an amount equal to the least of (i) the original principal balance of the related Mortgage Loan, (ii) the replacement value of the improvements that are part of the Mortgaged Property, and (iii) the maximum amount of flood insurance available for the related Mortgaged Property under the national flood insurance program.

If the Servicer obtains and maintains a blanket policy insuring against hazard losses on all of the Mortgage Loans, it shall have satisfied its obligations in the first sentence of this Section 3.10. The policy may contain a deductible clause on terms substantially equivalent to those commercially available and maintained by comparable servicers. If the policy contains a deductible clause and a policy complying with the first sentence of this Section 3.10 has not been maintained on the related Mortgaged Property, and if a loss that would have been covered by the required policy occurs, the Servicer shall deposit in the Certificate Account, without any right of reimbursement, the amount not otherwise payable under the blanket policy because of the deductible clause. In connection with its activities as Servicer of the Mortgage Loans, the Servicer agrees to present, on behalf of itself, the Depositor, and the Trustee for the benefit of the Certificateholders, claims under any blanket policy.

(b) The Servicer shall not take any action that would result in non-coverage under any applicable Primary Insurance Policy of any loss that, but for the actions of the Servicer, would have been covered thereunder. The Servicer shall not cancel or refuse to renew any Primary Insurance Policy that is in effect at the date of the initial issuance of the Certificates and is required to be kept in force hereunder unless the replacement Primary Insurance Policy for the canceled or non-renewed policy is maintained with a Qualified Insurer. The Servicer need not maintain any Primary Insurance Policy if maintaining the Primary Insurance Policy is prohibited by applicable law. The Servicer agrees, to the extent permitted by applicable law, to effect the timely payment of the premiums on each Primary Insurance Policy, and any costs not otherwise recoverable shall be recoverable by the Servicer from the related liquidation proceeds.

In connection with its activities as Servicer of the Mortgage Loans, the Servicer agrees to present, on behalf of itself, the Trustee and the Certificateholders, claims to the insurer under any Primary Insurance Policies and, in this regard, to take any reasonable action in accordance with the Servicing Standard necessary to permit recovery under any Primary Insurance Policies respecting defaulted Mortgage Loans. Any amounts collected by the Servicer under any Primary Insurance Policies shall be deposited in the Certificate Account.

Section 3.11 Enforcement of Due-On-Sale Clauses; Assumption Agreements.

(a) Except as otherwise provided in this Section 3.11, when any property subject to a Mortgage has been conveyed by the Mortgagor, the Servicer shall to the extent that it has knowledge of the conveyance and in accordance with the Servicing Standard, enforce any due-on-sale clause contained in any Mortgage Note or Mortgage, to the extent permitted under applicable law and governmental regulations, but only to the extent that enforcement will not adversely affect or jeopardize coverage under any Required Insurance Policy. Notwithstanding the foregoing, the Servicer is not required to exercise these rights with respect to a Mortgage Loan if the Person to whom the related Mortgaged Property has been conveyed or is proposed to be conveyed satisfies the conditions contained in the Mortgage Note and Mortgage related thereto and the consent of the mortgagee under the Mortgage Note or Mortgage is not otherwise so required under the Mortgage Note or Mortgage as a condition to the transfer.

If (i) the Servicer is prohibited by law from enforcing any due-on-sale clause, (ii) coverage under any Required Insurance Policy would be adversely affected, (iii) the Mortgage Note does not include a due-on-sale clause, or (iv) nonenforcement is otherwise permitted hereunder, the Servicer is authorized, subject to Section 3.11(b), to take or enter into an assumption and modification agreement from or with

the person to whom the property has been or is about to be conveyed, pursuant to which the person becomes liable under the Mortgage Note and, unless prohibited by applicable state law, the Mortgagor remains liable thereon. The Mortgage Loan must continue to be covered (if so covered before the Servicer enters into the agreement) by the applicable Required Insurance Policies.

The Servicer, subject to Section 3.11(b), is also authorized with the prior approval of the insurers under any Required Insurance Policies to enter into a substitution of liability agreement with the Person, pursuant to which the original Mortgagor is released from liability and the Person is substituted as Mortgagor and becomes liable under the Mortgage Note. Notwithstanding the foregoing, the Servicer shall not be deemed to be in default under this Section 3.11 because of any transfer or assumption that the Servicer reasonably believes it is restricted by law from preventing, for any reason whatsoever.

(b) Subject to the Servicer’s duty to enforce any due-on-sale clause to the extent set forth in Section 3.11(a), in any case in which a Mortgaged Property has been conveyed to a Person by a Mortgagor, and the Person is to enter into an assumption agreement or modification agreement or supplement to the Mortgage Note or Mortgage that requires the signature of the Trustee, or if an instrument of release signed by the Trustee is required releasing the Mortgagor from liability on the Mortgage Loan, the Servicer shall prepare and deliver to the Trustee for signature and shall direct the Trustee, in writing, to execute the assumption agreement with the Person to whom the Mortgaged Property is to be conveyed, and the modification agreement or supplement to the Mortgage Note or Mortgage or other instruments appropriate to carry out the terms of the Mortgage Note or Mortgage or otherwise to comply with any applicable laws regarding assumptions or the transfer of the Mortgaged Property to the Person. In connection with any such assumption, no material term of the Mortgage Note may be changed.

In addition, the substitute Mortgagor and the Mortgaged Property must be acceptable to the Servicer in accordance with its underwriting standards as then in effect. Together with each substitution, assumption, or other agreement or instrument delivered to the Trustee for execution by it, the Servicer shall deliver an Officer’s Certificate signed by a Servicing Officer stating that the requirements of this subsection have been met in connection with such Officer’s Certificate. The Servicer shall notify the Trustee that any substitution or assumption agreement has been completed by forwarding to the Trustee the original of the substitution or assumption agreement, which in the case of the original shall be added to the related Mortgage File and shall, for all purposes, be considered a part of the Mortgage File to the same extent as all other documents and instruments constituting a part of the Mortgage File. The Servicer will retain any fee collected by it for entering into an assumption or substitution of liability agreement as additional servicing compensation.

Section 3.12 Realization Upon Defaulted Mortgage Loans.

The Servicer shall use reasonable efforts in accordance with the Servicing Standard to foreclose on or otherwise comparably convert the ownership of assets securing such of the Mortgage Loans as come into and continue in default and as to which no satisfactory arrangements can be made for collection of delinquent payments. In connection with the foreclosure or other conversion, the Servicer shall follow the Servicing Standard and shall follow the requirements of the insurer under any Required Insurance Policy. The Servicer shall not be required to expend its own funds in connection with any foreclosure or towards the restoration of any property unless it determines (i) that the restoration or foreclosure will increase the proceeds of liquidation of the Mortgage Loan after reimbursement to itself of restoration expenses and (ii) that restoration expenses will be recoverable to it through Liquidation Proceeds (respecting which it shall have priority for purposes of withdrawals from the Certificate Account). The Servicer shall be responsible for all other costs and expenses incurred by it in any foreclosure proceedings. The Servicer is entitled to reimbursement of such costs and expenses from the liquidation proceeds with respect to the related Mortgaged Property, as provided in the definition of Liquidation

Proceeds. If the Servicer has knowledge that a Mortgaged Property that the Servicer is contemplating acquiring in foreclosure or by deed in lieu of foreclosure is located within a one mile radius of any site listed in the Expenditure Plan for the Hazardous Substance Clean Up Bond Act of 1984 or other site with environmental or hazardous waste risks known to the Servicer, the Servicer will, before acquiring the Mortgaged Property, consider the risks and only take action in accordance with its established environmental review procedures.

With respect to any REO Property, the deed or certificate of sale shall be taken in the name of the Trustee for the benefit of the Certificateholders, or its nominee, on behalf of the Certificateholders. The Trustee’s name shall be placed on the title to the REO Property solely as the Trustee hereunder and not in its individual capacity. The Servicer shall ensure that the title to the REO Property references the Pooling and Servicing Agreement and the Trustee’s capacity hereunder. Pursuant to its efforts to sell the REO Property, the Servicer shall either itself or through an agent selected by the Servicer protect and conserve the REO Property in accordance with the Servicing Standard.

The Servicer shall perform the tax reporting and withholding required by sections 1445 and 6050J of the Code with respect to foreclosures and abandonments, the tax reporting required by section 6050H of the Code with respect to the receipt of mortgage interest from individuals and, if required by section 6050P of the Code with respect to the cancellation of indebtedness by certain financial entities, by preparing any required tax and information returns, in the form required.

If the Trust Fund acquires any Mortgaged Property as aforesaid or otherwise in connection with a default or imminent default on a Mortgage Loan, the REO Property shall only be held temporarily, shall be actively marketed for sale, and the Servicer shall dispose of the Mortgaged Property as soon as practicable, and in any case before the end of the third calendar year following the calendar year in which the Trust Fund acquires the property. Notwithstanding any other provision of this Agreement, no Mortgaged Property acquired by the Trust Fund shall be rented (or allowed to continue to be rented) or otherwise used for the production of income by or on behalf of the Trust Fund.

The decision of the Servicer to foreclose on a defaulted Mortgage Loan shall be subject to a determination by the Servicer that the proceeds of the foreclosure would exceed the costs and expenses of bringing a foreclosure proceeding. The proceeds received from the maintenance of any REO Properties, net of reimbursement to the Servicer for costs incurred (including any property or other taxes) in connection with maintenance of the REO Properties and net of unreimbursed Servicing Fees, Advances, and Servicing Advances, shall be applied to the payment of principal of and interest on the related defaulted Mortgage Loans (with interest accruing as though the Mortgage Loans were still current and adjustments, if applicable, to the Mortgage Rate were being made in accordance with the Mortgage Note) and all such proceeds shall be deemed, for all purposes in this Agreement, to be payments on account of principal and interest on the related Mortgage Notes and shall be deposited into the Certificate Account. To the extent the net proceeds received during any calendar month exceeds the amount attributable to amortizing principal and accrued interest at the related Mortgage Rate on the related Mortgage Loan for the calendar month, the excess shall be considered to be a partial prepayment of principal of the related Mortgage Loan.

The proceeds from any liquidation of a Mortgage Loan, as well as any proceeds from an REO Property, will be applied in the following order of priority: first, to reimburse the Servicer for any related unreimbursed Servicing Advances or Servicing Fees or for any related unreimbursed Advances, as applicable; second, to reimburse the Servicer, as applicable, and to reimburse the Certificate Account for any Nonrecoverable Advances (or portions thereof) that were previously withdrawn by the Servicer pursuant to Section 3.09(a)(iii) that related to the Mortgage Loan; third, to accrued and unpaid interest (to the extent no Advance has been made for such amount or any such Advance has been reimbursed) on the

Mortgage Loan or related REO Property, at the Adjusted Net Mortgage Rate to the Due Date occurring in the month in which such amounts are required to be distributed; and fourth, as a recovery of principal of the Mortgage Loan. The Servicer will retain any Excess Proceeds from the liquidation of a Liquidated Mortgage Loan as additional servicing compensation pursuant to Section 3.15.

The Servicer may agree to a modification of any Mortgage Loan at the request of the related Mortgagor if (i) the modification is in lieu of a refinancing and (ii) the Servicer purchases that Mortgage Loan from the Trust Fund as described below. Upon the agreement of the Servicer to modify a Mortgage Loan in accordance with the preceding sentence, the Servicer shall purchase that Mortgage Loan and all interest of the Trustee in that Mortgage Loan shall automatically be deemed transferred and assigned to the Servicer and all benefits and burdens of ownership thereof, including the right to accrued interest thereon from the date of purchase and the risk of default thereon, shall pass to the Servicer. The Servicer shall promptly deliver to the Trustee a certification of a Servicing Officer to the effect that all requirements of this paragraph have been satisfied with respect to a Mortgage Loan to be repurchased pursuant to this paragraph.

The Servicer shall deposit the Purchase Price for any Mortgage Loan repurchased pursuant to Section 3.12 in the Certificate Account pursuant to Section 3.06 within one Business Day after the purchase of the Mortgage Loan. Upon receipt by the Trustee of written notification of any such deposit signed by a Servicing Officer, the Trustee shall release to the Servicer the related Mortgage File and shall execute and deliver such instruments of transfer or assignment, in each case without recourse, as shall be necessary to vest in the Servicer any Mortgage Loan previously transferred and assigned pursuant hereto. The Servicer covenants and agrees to indemnify the Trust Fund against any liability for any “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, or any purchase of a Mortgage Loan by the Servicer in connection with a modification (but such obligation shall not prevent the Servicer or any other appropriate Person from contesting any such tax in appropriate proceedings and shall not prevent the Servicer from withholding payment of such tax, if permitted by law, pending the outcome of such proceedings). The Servicer shall have no right of reimbursement for any amount paid pursuant to the foregoing indemnification, except to the extent that the amount of any tax, interest, and penalties, together with interest thereon, is refunded to the Trust Fund.

Section 3.13 Trustee to Cooperate; Release of Mortgage Files.

Upon the payment in full of any Mortgage Loan, or the receipt by the Servicer of a notification that payment in full will be escrowed in a manner customary for such purposes, the Servicer will immediately notify the Trustee by delivering a Request for Release substantially in the form of Exhibit N. Upon receipt of the request, the Trustee shall promptly release the related Mortgage File to the Servicer, and the Trustee shall at the Servicer’s direction execute and deliver to the Servicer the request for reconveyance, deed of reconveyance, or release or satisfaction of mortgage or such instrument releasing the lien of the Mortgage in each case provided by the Servicer, together with the Mortgage Note with written evidence of cancellation thereon. The Servicer is authorized to cause the removal from the registration on the MERS System of such Mortgage and to execute and deliver, on behalf of the Trustee and the Certificateholders or any of them, any and all instruments of satisfaction or cancellation or of partial or full release. Expenses incurred in connection with any instrument of satisfaction or deed of reconveyance shall be chargeable to the related Mortgagor.

From time to time and as shall be appropriate for the servicing or foreclosure of any Mortgage Loan, including for such purpose collection under any policy of flood insurance, any fidelity bond or errors or omissions policy, or for the purposes of effecting a partial release of any Mortgaged Property from the lien of the Mortgage or the making of any corrections to the Mortgage Note or the Mortgage or

any of the other documents included in the Mortgage File, the Trustee shall, upon delivery to the Trustee of a Request for Release in the form of Exhibit M signed by a Servicing Officer, release the Mortgage File to the Servicer or its designee. Subject to the further limitations set forth below, the Servicer shall cause the Mortgage File or documents so released to be returned to the Trustee when the need therefor by the Servicer no longer exists, unless the Mortgage Loan is liquidated and the proceeds thereof are deposited in the Certificate Account, in which case the Servicer shall deliver to the Trustee a Request for Release in the form of Exhibit N, signed by a Servicing Officer.

If the Servicer at any time seeks to initiate a foreclosure proceeding in respect of any Mortgaged Property as authorized by this Agreement, the Servicer shall deliver to the Trustee, for signature, as appropriate, any court pleadings, requests for trustee’s sale, or other documents necessary to effectuate such foreclosure or any legal action brought to obtain judgment against the Mortgagor on the Mortgage Note or the Mortgage or to obtain a deficiency judgment or to enforce any other remedies or rights provided by the Mortgage Note or the Mortgage or otherwise available at law or in equity.

Section 3.14 Documents, Records and Funds in Possession of the Servicer to be Held for the Trustee.

The Servicer shall account fully to the Trustee for any funds it receives or otherwise collects as Liquidation Proceeds or Insurance Proceeds in respect of any Mortgage Loan. All Mortgage Files and funds collected or held by, or under the control of, the Servicer in respect of any Mortgage Loans, whether from the collection of principal and interest payments or from Liquidation Proceeds, including any funds on deposit in the Certificate Account, shall be held by the Servicer for and on behalf of the Trustee and shall be and remain the sole and exclusive property of the Trustee, subject to the applicable provisions of this Agreement. The Servicer also agrees that it shall not create, incur or subject any Mortgage File or any funds that are deposited in the Certificate Account, Distribution Account, or any Escrow Account, or any funds that otherwise are or may become due or payable to the Trustee for the benefit of the Certificateholders, to any claim, lien, security interest, judgment, levy, writ of attachment, or other encumbrance, or assert by legal action or otherwise any claim or right of setoff against any Mortgage File or any funds collected on, or in connection with, a Mortgage Loan, except, however, that the Servicer shall be entitled to set off against and deduct from any such funds any amounts that are properly due and payable to the Servicer under this Agreement.

Section 3.15 Servicing Compensation.

The Servicer may retain or withdraw (as and to the extent provided in this Agreement) from the Certificate Account the Servicing Fee for each Mortgage Loan for the related Distribution Date. If the Servicer directly services a Mortgage Loan, the Servicer may retain the Servicing Fee for its own account as compensation for performing services. Notwithstanding the foregoing, the Servicing Fee payable to the Servicer shall be reduced by the lesser of the aggregate of the Prepayment Interest Shortfalls with respect to the Distribution Date and the aggregate Compensating Interest for the Distribution Date.

Additional servicing compensation in the form of Excess Proceeds, Prepayment Interest Excess, assumption fees and all income net of any losses realized from Permitted Investments shall be retained by the Servicer to the extent not required to be deposited in the Certificate Account pursuant to Section 3.06. The Servicer shall be required to pay all expenses incurred by it in connection with its servicing activities hereunder (including the payment of any premiums for hazard insurance, and any Primary Insurance Policy and maintenance of the other forms of insurance coverage required by this Agreement) and shall not be entitled to reimbursement therefor except as specifically provided in this Agreement.

Section 3.16 Access to Certain Documentation.

The Servicer shall provide to the OTS and the FDIC and to comparable regulatory authorities supervising Holders of Certificates and Certificate Owners and the examiners and supervisory agents of the OTS, the FDIC, and such other authorities, access to the documentation regarding the Mortgage Loans required by applicable regulations of the OTS and the FDIC. Access shall be afforded without charge, but only upon reasonable prior written request and during normal business hours at the offices designated by the Servicer. Nothing in this Section 3.16 shall limit 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 3.16 as a result of such obligation shall not constitute a breach of this Section 3.16.

Section 3.17 Annual Statement as to Compliance.

(a) By March 15 of each year, commencing with 2008, the Servicer shall deliver to the Trustee via electronic mail (XXXXX.Xxxxxxxxxxxxx@xx.xxx) and the Depositor an Officer’s Certificate signed by two Servicing Officers stating, as to each signer thereof, that (i) a review of the activities of the Servicer during the preceding calendar year (or applicable portion thereof) and of the performance of the Servicer under this Agreement has been made under such officer’s supervision, and (ii) to the best of such officer’s knowledge, based on the review, the Servicer has fulfilled all its obligations under this Agreement, in all material respects throughout the year (or applicable portion thereof), or, if there has been a failure to fulfill any obligation in any material respect, specifying each failure known to the officer and the nature and status thereof.

(b) [Reserved].

(c) Copies of such statement shall be provided by the Trustee to any Certificateholder or Certificate Owner upon request at the Servicer’s expense, provided such statement is delivered by the Servicer to the Trustee.

Section 3.18 Errors and Omissions Insurance; Fidelity Bonds.

The Servicer shall obtain and maintain in force (a) policies of insurance covering errors and omissions in the performance of its obligations as Servicer hereunder and (b) a fidelity bond covering its officers, employees, and agents. Each policy and bond shall, together, comply with the requirements from time to time of FNMA or FHLMC for persons performing servicing for mortgage loans purchased by FNMA or FHLMC. If any policy or bond ceases to be in effect, the Servicer shall obtain a comparable replacement policy or bond from an insurer or issuer meeting the above requirements as of the date of the replacement.

Section 3.19 The Swap Contract.

The Depositor shall cause the Supplemental Interest Trustee, on behalf of the Supplemental Interest Trust, to enter into the Swap Contract. The Supplemental Interest Trustee’s rights to receive certain proceeds of the Swap Contract shall not be an asset of the Trust Fund or of any REMIC. The Supplemental Interest Trustee shall deposit any amounts received from time to time from the Swap Counterparty into the Swap Account.

The Supplemental Interest Trustee shall (i) be subject to a standard of care and (ii) be entitled to all of the rights, privileges, immunities and indemnities, in each case identical to that of the Trustee under Article Eight of this Agreement.

Upon the Supplemental Interest Trustee obtaining actual knowledge of the rating of the Swap Counterparty falling below the relevant levels set forth in the Swap Contract (provided, however, that the Supplemental Interest Trustee shall have no obligation to conduct an independent investigation or inquiry in relation thereto), the Depositor shall instruct the Supplemental Interest Trustee in writing to enforce its rights thereunder. Such Instructions shall be specific as to mode or method of enforcement. If the Swap Counterparty appropriately elects to post collateral under the Credit Support Annex executed on the Closing Date, the Supplemental Interest Trustee shall demand payment of the Delivery Amount (as defined in the ISDA Credit Support Annex). The Supplemental Interest Trustee shall set up the Collateral Account in accordance with Section 3.06 to hold such cash or other eligible investments pledged under such ISDA Credit Support Annex. Any cash or other eligible investments pledged under an ISDA Credit Support Annex shall not be part of the Swap Account or the Distribution Account unless they are applied in accordance with such ISDA Credit Support Annex to make a payment due to the Supplemental Interest Trustee pursuant to the Swap Contract.

Upon the Supplemental Interest Trustee obtaining actual knowledge of an Event of Default (as defined in the Swap Contract) or Termination Event (as defined in the Swap Contract) for which the Supplemental Interest Trustee has the right to designate an Early Termination Date (as defined in the Swap Contract) (provided, however, that the Supplemental Interest Trustee shall have no obligation to conduct an independent investigation or inquiry in relation thereto), the Depositor shall instruct the Supplemental Interest Trustee in writing as to whether to designate an Early Termination Date; provided, however, that the Supplemental Interest Trustee shall provide written notice to each Rating Agency following the Event of Default or Termination Event. Upon the termination of the Swap Contract under the circumstances contemplated by this Section 3.19(b), the Supplemental Interest Trustee shall use its reasonable best efforts to enforce its rights as may be permitted by the terms of the Swap Contract and consistent with the terms of this Agreement.

Notwithstanding any other provision in this Agreement, in the event that the Swap Contract is terminated and the Supplemental Interest Trust enters into a replacement swap contract and the Supplemental Interest Trust is entitled to receive a payment from a replacement swap counterparty, the Supplemental Interest Trustee shall direct the replacement swap counterparty to make such payment to the Swap Account in accordance with the provisions of this paragraph. The Supplemental Interest Trustee shall pay to the Swap Counterparty the lesser of (x) the amount so received and (y) any Swap Termination Payment owed to the Swap Counterparty (to the extent not already paid by the Supplemental Interest Trust) that is being replaced immediately upon receipt of the replacement swap counterparty payment, regardless of whether the date of receipt thereof is a Distribution Date; provided that to the extent that the replacement swap counterparty payment is less than the Swap Termination Payment owed to the Swap Counterparty, any remaining amounts will be paid to the Swap Counterparty on the subsequent Distribution Date (unless the replacement swap counterparty payment is paid to the Swap Counterparty on a Distribution Date, in which case such remaining amounts will be paid on such Distribution Date) in accordance with the priority of payments described in Section 4.02 of this Agreement. For the avoidance of doubt, the parties agree that the Swap Counterparty shall have first priority to any replacement swap counterparty payment over the payment by the Supplemental Interest Trust to Certificateholders, any servicer, any custodian, the Trustee, Supplemental Interest Trustee or any other Person.

In the event that the Swap Counterparty pays any Swap Termination Payment to the Supplemental Interest Trustee, any portion of such Swap Termination Payment paid by the Swap Counterparty that is remitted to the Supplemental Interest Trustee shall be available to pay any upfront amount due to a replacement swap provider with respect to the related replacement swap contract, and thereafter for distribution in the manner described in Section 4.02(c).

The Swap Counterparty shall be an express third party beneficiary of any obligation under this Agreement that specifically affects its rights to receive any payment due to it and available to be paid to it to the extent received by the Supplemental Interest Trustee under this Agreement or to the return of collateral under this Agreement and any other express rights of the Swap Counterparty explicitly set forth under this Agreement and the Swap Contract, and for purposes of the standard of care under this Agreement, solely to the extent of the Supplemental Interest Trustee’s negligence or willful misconduct as it relates to the above described obligations owed to the Swap Counterparty by the Supplemental Interest Trustee under this Agreement.

Notwithstanding anything herein to the contrary, any responsibility of the Supplemental Interest Trustee hereunder or under the Swap Contract to make any payment to the Swap Counterparty, or receive any payment from the Swap Counterparty, as applicable, shall be subject to the receipt of timely, accurate and available information from the Servicer and the Swap Counterparty pursuant to the terms of this Agreement and Swap Contract, as applicable.

Section 3.20 Notification of Adjustments.

On each Adjustment Date, the Servicer shall make interest rate adjustments for each Mortgage Loan in compliance with the requirements of the related Mortgage and Mortgage Note and applicable regulations. The Servicer shall execute and deliver the notices required by each Mortgage and Mortgage Note and applicable regulations regarding interest rate adjustments. The Servicer also shall provide timely notification to the Trustee of all applicable data and information regarding such interest rate adjustments and the Servicer’s methods of implementing such interest rate adjustments. Upon the discovery by the Servicer or the Trustee that the Servicer has failed to adjust or has incorrectly adjusted a Mortgage Rate or a monthly payment pursuant to the terms of the related Mortgage Note and Mortgage, the Servicer shall immediately deposit in the Certificate Account from its own funds the amount of any loss caused thereby without reimbursement therefor; provided, however, the Servicer shall not be liable with respect to any interest rate adjustments made by any servicer prior to the Servicer.

Section 3.21 Prepayment Charges.

(a) The Servicer will not waive any part of any Prepayment Charge unless the waiver relates to a default or a reasonably foreseeable default, the Prepayment Charge would cause an undue hardship to the related borrower, the Mortgaged Property is sold by the Mortgagor, the collection of any Prepayment Charge would violate any relevant law or regulation or the waiving of the Prepayment Charge 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 Prepayment Charge and related Mortgage Loan and doing so is standard and customary in servicing similar Mortgage Loans (including any waiver of a Prepayment Charge in connection with a refinancing of a Mortgage Loan that is related to a default or a reasonably foreseeable default). The Servicer will not waive a Prepayment Charge in connection with a refinancing of a Mortgage Loan that is not related to a default or a reasonably foreseeable default.

(b) If a Prepayment Charge is waived other than as permitted by the prior paragraph, then the Servicer is required to pay the amount of such waived Prepayment Charge, for the benefit of the Holders of the Class P-1 or Class P-2 Certificates, as applicable, by depositing such amount into the Distribution Account from its own funds, without any right of reimbursement therefor, together with and at the time that the amount prepaid on the related Mortgage Loan is required to be deposited into the Distribution Account.

(c) The Seller represents and warrants to the Depositor and the Trustee, as of the Closing Date, that the information relating to the type of Prepayment Charges and the Prepayment Charge Period in the

Mortgage Loan Schedule is complete and accurate in all material respects at the dates as of which the information is furnished and each Prepayment Charge is permissible and enforceable in accordance with its terms under applicable state law, except as the enforceability thereof is limited due to acceleration in connection with a foreclosure or other involuntary payment.

(d) Upon discovery by the Servicer or upon actual knowledge by a Responsible Officer of the Trustee (provided, however, that the Trustee shall have no obligation to conduct an independent investigation or inquiry in relation thereto) of a breach of the foregoing clause (c) that materially and adversely affects the right of the Holders of the Class P-1 or Class P-2 Certificates, as applicable, to any Prepayment Charge, the party discovering the breach shall give prompt written notice to the other parties. Within 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 Certificate Account the amount of the Prepayment Charge that would otherwise be due from the Mortgagor, less any amount representing such Prepayment Charge previously collected and paid by the Servicer into the Certificate Account.

Section 3.22 Late Payment Fees.

(a) The Servicer shall not waive any part of any Late Payment Fee unless (i) the collection of any Late Payment Fee would violate any relevant law or regulation or (ii) the waiving of the Late Payment 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 Late Payment Fee and related Mortgage Loan and doing so is standard and customary in servicing similar Mortgage Loans (including the waiver of a Late Payment Fee in connection with a refinancing of a Mortgage Loan that is related to a default or reasonably foreseeable default).

(b) If the covenants made by the Servicer in clause (a) above is breached, the Servicer must pay into the Certificate Account prior to the Distribution Account Deposit Date following the end of the related Prepayment Period the amount of the waived Late Payment Fee.

(c) The Servicer shall remit Late Payment Fees assessable and not waived pursuant to clause (a) above in accordance with Section 3.09.

ARTICLE FOUR

Distributions and Advances by the Servicer

Section 4.01 Advances.

(a) The Servicer shall determine on or before each Servicer Advance Date whether it is required to make an Advance pursuant to the definition thereof. If the Servicer determines it is required to make an Advance, it shall, on or before the Servicer Advance Date, either (i) deposit into the Certificate Account an amount equal to the Advance or (ii) make an appropriate entry in its records relating to the Certificate Account that any Amount Held for Future Distribution has been used by the Servicer in discharge of its obligation to make any such Advance. Any funds so applied shall be replaced by the Servicer by deposit in the Certificate Account no later than the close of business on the next Servicer Advance Date. The Servicer shall be entitled to be reimbursed from the Certificate Account for all Advances of its own funds made pursuant to this Section 4.01 as provided in Section 3.09. The obligation to make Advances with respect to any Mortgage Loan shall continue if such Mortgage Loan has been foreclosed or otherwise terminated and the Mortgaged Property has not been liquidated. The Servicer shall inform the Trustee of the amount of the Advance to be made on each Servicer Advance Date no later than the second Business Day before the related Distribution Date.

(b) If the Servicer determines that it will be unable to comply with its obligation to make the Advances as and when described in the second sentence of Section 4.01(a), it shall use its best efforts to give written notice thereof to the Trustee (each such notice an “Advance Notice”; and such notice may be given by telecopy), not later than 3:00 P.M., New York time, on the Business Day immediately preceding the related Servicer Advance Date, specifying the amount that it will be unable to deposit (each such amount an “Advance Deficiency”) and certifying that such Advance Deficiency constitutes an Advance hereunder and is not a Nonrecoverable Advance. If the Trustee receives a Trustee Advance Notice on or before 3:00 P.M., New York time on a Servicer Advance Date, the Trustee is entitled to immediately terminate the Servicer under Section 7.01, and shall, not later than 3:00 P.M., New York time, on the related Distribution Date, deposit in the Distribution Account an amount equal to the Advance Deficiency identified in such Trustee Advance Notice unless it is prohibited from so doing by applicable law. Notwithstanding the foregoing, the Trustee shall not be required to make such deposit if the Trustee shall have received written notification from the Servicer that the Servicer has deposited or caused to be deposited in the Certificate Account an amount equal to such Advance Deficiency by 3:00 P.M. New York time on the related Distribution Date. If the Trustee has not terminated the Servicer, the Servicer shall reimburse the Trustee for the amount of any Advance (including interest at the Prime Rate on the day of such reimbursement published in The Wall Street Journal) on such amount, made by the Trustee pursuant to this Section 4.01(b) not later than the second day following the related Servicer Advance Date. In the event that the Servicer does not reimburse the Trustee in accordance with the requirements of the preceding sentence, the Trustee shall immediately (a) terminate all of the rights and obligations of the Servicer under this Agreement in accordance with Section 7.01 and (b) subject to the limitations set forth in Section 3.05, assume all of the rights and obligations of the Servicer hereunder.

(c) The Servicer shall, not later than the close of business on the Business Day immediately preceding each Servicer Advance Date, deliver to the Trustee a report (in form and substance reasonably satisfactory to the Trustee) that indicates (i) the Mortgage Loans with respect to which the Servicer has determined that the related Scheduled Payments should be advanced and (ii) the amount of the related Scheduled Payments. The Servicer shall deliver to the Trustee on the related Servicer Advance Date an Officer’s Certificate of a Servicing Officer indicating the amount of any proposed Advance determined by the Servicer to be a Nonrecoverable Advance.
