THIS POOLING AND SERVICING AGREEMENT, dated as of June 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 (the “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 any amounts in respect of waived Prepayment Charges paid by the Servicer to the Class P Certificates 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 and Class L Certificates, will represent ownership of one or more regular interests in the Master REMIC for purposes of the REMIC Provisions. The Class A-R represents 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. 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 Certificates pursuant to Section 3.20(b) will be treated as paid directly by the Servicer to the Class P 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 or by or through the Grantor Trust described in 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 Assumed Balance of Loan Group 1)	(1)	(2)	1
B-1 (0.1% of the Assumed Balance of Loan Group 1)	(1)	(2)	1
C-1 (Excess of Loan Group 1)	(1)	(2)	1
A-2 (0.9% of the Assumed Balance of Loan Group 2)	(1)	(2)	2
B-2 (0.1% of the Assumed Balance of Loan Group 2)	(1)	(2)	2
C-2 (Excess of Loan Group 2)	(1)	(2)	2
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 Assumed Balance of its corresponding Loan Group. Each Class B Interest will have a principal balance initially equal to 0.1% of the the Assumed Balance 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-1 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 Interests will not bear interest. The Class 1-P Interests will be entitled to 100% of any Prepayment Charges paid on the Mortgage Loans.

(4) The Weighted Average Adjusted Net Mortgage Rate of the Mortgage Loans in Loan Group 1.

(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 and Class 1-$100 Interests equal to the principal balances of the Class P and Class A-R Certificates, respectively, for such Distribution Date.

(3) If 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 Assumed Balance and 0.1% of the Assumed Balance; 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 Assumed Balance. 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 Mortgage Loans in 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
Class 2-1-A-1	(1)	Variable(2)	Class 1-A-1, 1-A-2

Class 2-B-6	(1)	Variable(4)	Class B-6
Class 2-P	$100	(5)	Class P
Class R-2	(8)	(6)	N/A

(1)	On each Distribution Date, Realized Losses and payments of principal will be allocated to each REMIC 2 Regular Interest in the same amounts as they are allocated to their Corresponding Class of Certificates.

(2)	These Interests will bear interest during each Accrual Period for any Distribution Date at a per annum rate equal to the Weighted Average Adjusted Net Mortgage Rate of the Group 1 Mortgage Loans as of that Distribution Date.

(3)	These Interests will bear interest during each Accrual Period for any Distribution Date at a per annum rate equal to the Weighted Average Adjusted Net Mortgage Rate of the Group 2 Mortgage Loans as of that Distribution Date.

(4)	The Pass-Through Rate for each such Class for each Interest Accrual Period for any Distribution Date will be a per annum rate equal to the Calculation Rate.

(5)	The Class 2-P Interests will not bear interest. The Class 2-P Interests will be entitled to 100% of any Prepayment Charges paid on the Class P Certificates.

(6)	The Class R-2 Interest is the sole class of residual interest in REMIC 2. It has no principal balance and pays no principal or interest.

(1)

The Pass-Through Rate for this Class of 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. The Pass-Through Rate for this Class of Certificates for the Interest Accrual Period related to the first Distribution Date is 6.27487% per annum.

(2)

The Pass-Through Rate for the Class 2-A-1 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 minus the Pass-Through Rate of the Class 2-A-X Certificates. The Pass-Through Rate for the Class 2-A-1 Certificates for the Interest Accrual Period related to the first Distribution Date is 6.00393% per annum.

(3)	This Class of Certificates will be Notional Amount Certificates, will have no Class Certificate Balance, will pay no principal and will be entitled to distributions of interest on its Notional Amount.

(4)	The Pass-Through Rate for the Class 2-A-X Certificates for the Interest Accrual Period related to any Distribution Date (x) up to and including the Distribution Date in June 2017, will equal 0.48000% per annum, and (y) any Distribution Date thereafter, will equal 0.00%.

(5)	Minimum denomination is based on the Notional Amount of the Class.

(6)

The Pass-Through Rate for each Class of Subordinated Certificates for the 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 6.40842% per annum. For federal income tax purposes, the Pass-Through Rate for each Class of Subordinated Certificates will be the Calculation Rate.

(7)

The Class P Certificates will not be entitled to any interest, but will be entitled to 100% of any Prepayment Charges collected on the Mortgage Loans. All amounts in respect of waived Prepayment Charges paid by the Servicer to the Class P Certificates pursuant to Section 3.20(b) will be treated as paid directly by the Servicer to the Class P Certificates and not as paid by or through any REMIC created under this Agreement. The Class P 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 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.

(a) The Seller, concurrently with the execution and delivery of this Agreement, hereby transfers to the Depositor, without recourse, all the interest of the Seller in each Mortgage Loan, including all interest and principal received or receivable by the Seller on each Mortgage Loan after the Cut-off Date and all interest and principal payments on each Mortgage Loan received before the Cut-off Date for installments of interest and principal due after the Cut-off Date but not including payments of principal and interest due by the Cut-off Date. By the Closing Date, the Seller shall deliver to the Depositor or, at the Depositor’s direction, to the Trustee or other designee of the Depositor, the Mortgage File for each Mortgage Loan listed in the Mortgage Loan Schedule (except that, in the case of Mortgage Loans that are Delay Delivery Mortgage Loans, such delivery may take place within five Business Days of the Closing Date) as of the Closing Date. The delivery of the Mortgage Files shall be made against payment by the Depositor of the purchase price, previously agreed to by the Seller and Depositor, for the Mortgage Loans. With respect to any Mortgage Loan that does not have a first payment date on or before the Due Date in the month of the first Distribution Date, the Seller shall deposit into the Distribution Account on the first Distribution Account Deposit Date an amount equal to one month’s interest at the related Adjusted Mortgage Rate on the Cut-off Date Principal Balance of such Mortgage Loan. Also on the Closing Date the Depositor shall deposit $100 into the Certificate Account for the benefit of the Class P Certificates.

(b) The Depositor, concurrently with the execution and delivery of this Agreement, hereby transfers to the Trustee for the benefit of the Certificateholders, without recourse, all the interest of the Depositor in the Trust Fund, together with the Depositor’s right to require the Seller to cure any breach of a representation or warranty made in this Agreement by the Seller or to repurchase or substitute for any affected Mortgage Loan in accordance with this Agreement.

(c) In connection with the transfer and assignment of each Mortgage Loan, the Depositor has delivered (or, in the case of the Delay Delivery Mortgage Loans, will deliver to the Trustee within the time periods specified in the definition of Delay Delivery Mortgage Loans), for the benefit of the Certificateholders the following documents or instruments with respect to each Mortgage Loan so assigned:

(i) The original Mortgage Note, endorsed by manual or facsimile signature in blank in the following form: “Pay to the order of _______________ ______________without recourse,” with all intervening endorsements showing a complete chain of endorsement from the originator to the Person endorsing the Mortgage Note (each endorsement being sufficient to transfer all interest of the party so endorsing, as noteholder or assignee thereof, in that Mortgage Note) or a lost note affidavit for any Lost Mortgage Note from the Seller stating that the original Mortgage Note was lost or destroyed, together with a copy of the Mortgage Note.

(ii) Except as provided below and for each Mortgage Loan that is not a MERS Mortgage Loan, the original recorded Mortgage or a copy of such Mortgage certified by the Seller as being a true and complete copy of the Mortgage (or, in the case of a Mortgage for which the related Mortgaged Property is located in the Commonwealth of Puerto Rico, a true copy of the Mortgage certified as such by the applicable notary) and in the case of each MERS Mortgage Loan, the original Mortgage, noting the presence of the MIN of the Mortgage Loans and either language indicating that the Mortgage Loan is a MOM Loan if the Mortgage Loan is a MOM Loan or if the Mortgage Loan was not a MOM Loan at origination, the original Mortgage and the assignment thereof to MERS, with evidence of recording indicated thereon, or a copy of the Mortgage certified by the public recording office in which such Mortgage has been recorded;

(iii) In the case of a Mortgage Loan that is not a MERS Mortgage Loan, a duly executed assignment of the Mortgage (which may be included in a blanket assignment or assignments), together with, except as provided below, all interim recorded assignments of the mortgage (each assignment, when duly and validly completed, to be in recordable form and sufficient to effect the assignment of and transfer to its assignee of the Mortgage to which the assignment relates). If the related Mortgage has not been returned from the applicable public recording office, the assignment of the Mortgage may exclude the information to be provided by the recording office. The assignment of Mortgage need not be delivered in the case of a Mortgage for which the related Mortgage Property is located in the Commonwealth of Puerto Rico.

(iv) The original or copies of each assumption, modification, written assurance, or substitution agreement.

(v) Except as provided below, the original or duplicate original lender’s title policy and all its riders.

(vi) The originals of the following documents for each Cooperative Loan:

(A)	the Co-op Shares, together with a stock power in blank;

(B)	the executed Security Agreement;

(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 hereof 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.

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.

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.

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. 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.

(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 seriously delinquent or defaulted Mortgage Loan, 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 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, except as provided in the immediately succeeding sentence, 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. With respect to no more than 5% of the Mortgage Loans (measured by aggregate Cut-off Date Principal Balance of the Mortgage Loans), the Servicer may extend the maturity of a Mortgage Loan past the date on which the final payment is due on the latest maturing Mortgage Loan as of the Cut-off Date, but in no event more than one year past such date. In the event of any such arrangement, the Servicer shall make Advances on the related Mortgage Loan in accordance with Section 4.01 during the scheduled period in accordance with the amortization schedule of the Mortgage Loan without modification thereof because of the arrangements. 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 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. 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) 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 not later than 30 days and not more than 45 days prior to any change of this Agreement.

(h) 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 and the Distribution 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.

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. 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 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 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 3.20 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 Certificates, 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 in the Prepayment Charge Schedule (including the attached prepayment charge summary) 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 Certificates 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 3.21 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.

Section 4.02 Priorities of Distribution.

(e) Notwithstanding the priority and allocation contained in Section 4.02(a)(4), if, with respect to any Class of Subordinated Certificates, on any Distribution Date the sum of the related Class Subordination Percentages of such Class and of all Classes of Subordinated Certificates that have a higher numerical Class designation than such Class (the “Applicable Credit Support Percentage”) is less than the Original Applicable Credit Support Percentage for such Class, no distribution of Principal Prepayments on the Mortgage Loans will be made to any such Classes (the “Restricted Classes”) and the amount of such Principal Prepayments otherwise distributable to the Restricted Classes shall be distributed to the Classes of Subordinated Certificates having lower numerical Class designations than such Class, pro rata, based on their respective Class Certificate Balances immediately prior to such Distribution Date and shall be distributed in the sequential order set forth in Section 4.02(a)(4). Notwithstanding the foregoing, the Class of Subordinated Certificates then outstanding with the lowest numerical class designation shall not be a Restricted Class.

(f) If the amount of a Realized Loss on a Mortgage Loan in a Loan Group has been reduced by application of Subsequent Recoveries with respect to such Mortgage Loan, the amount of such Subsequent Recoveries will be applied sequentially, in the order of payment priority, to increase the Class Certificate Balance of each related Class of Certificates to which Realized Losses have been allocated, but in each case by not more than the amount of Realized Losses previously allocated to that Class of Certificates pursuant to Section 4.05. Holders of such Certificates will not be entitled to any payment in respect of the Class Optimal Interest Distribution Amount on the amount of such increases for any Interest Accrual Period preceding the Distribution Date on which such increase occurs. Any such increases shall be applied to the Certificate Balance of each Certificate of such Class in accordance with its respective Percentage Interest.

Section 4.03 Cross-Collateralization; Adjustments to Available Funds

(a) [Reserved].

(b) If on any Distribution Date the Class Certificate Balance of the Senior Certificates in a Loan Group is greater than the aggregate Stated Principal Balance of the Mortgage Loans in such Loan Group (each, an “Undercollateralized Group”), then the Trustee shall reduce the Available Funds of the other Loan Group(s) that are not undercollateralized (each, an “Overcollateralized Group”), as follows:

(i) to add to the Available Funds of the Undercollateralized Group an amount equal to the lesser of (a) one month’s interest on the Transfer Payment Received of the Undercollateralized Group at the Weighted Average Adjusted Net Mortgage Rate applicable to the Undercollateralized Group and (b) Available Funds of the Overcollateralized Group(s) remaining after making distributions to the Certificates of the Overcollateralized Group(s) on such Distribution Date pursuant to Section 4.02; and

(ii) to the Senior Certificates of the Undercollateralized Group, to the extent of the principal portion of Available Funds of the Overcollateralized Group(s) remaining after making distributions to the Senior Certificates of the Overcollateralized Group(s) on such Distribution Date pursuant to Section 4.02, until the Class Certificate Balance of the Senior Certificates of such Undercollateralized Group equals the aggregate Stated Principal Balance of the Mortgage Loans in the related Loan Group.

The portion of the payment received by the Undercollateralized Group allocable to principal is referred to as a “Transfer Payment Received.” The portion of the payment made by the Overcollateralized Group allocable to principal is referred to as a “Transfer Payment Made.”

Section 4.04 [Reserved].

Section 4.05 Allocation of Realized Losses.

(a) On or prior to each Determination Date, the Trustee shall determine the total amount of Realized Losses, including Excess Losses, with respect to each related Distribution Date.

Realized Losses with respect to any Distribution Date shall be allocated as follows:

(i) [reserved]; and

(A) any Realized Loss (other than any Excess Loss) on the Mortgage Loans in a Loan Group shall be allocated first to the Subordinated Certificates in reverse order of their respective numerical Class designations (beginning with the Class of Subordinated Certificates then outstanding with the highest numerical Class designation) until the respective Class Certificate Balance of each such Class is reduced to zero, and second to the Classes of Senior Certificates of the related Senior Certificate Group (other than the Notional Amount Certificates) as follows: (x) any Realized Losses, other than Excess Losses, on the Group 1 Mortgage Loans will be allocated, sequentially, to the Class 1-A-2 and the Class 1-A-1 Certificates, in that order, until their respective Class Certificate Balances are reduced to zero; (y) any Realized Losses, other than Excess Losses, on the Group 2 Mortgage Loans will be allocated to the Class 2-A-1 Certificates, until its Class Certificate Balance is reduced to zero.

(B) On each Distribution Date, Excess Losses on the Mortgage Loans in a Loan Group shall be allocated pro rata among the Classes of Senior Certificates of the related Senior Certificate Group and the Subordinated Certificates as follows: (i) in the case of the Senior Certificates, the Senior Percentage of such Excess Losses shall be allocated among the Classes of Senior Certificates in the related Senior Certificate Group (other than the Notional Amount Certificates), pro rata, on the basis of their respective Class Certificate Balances immediately prior to the related Distribution Date and (ii) in the case of the Subordinated Certificates, the Subordinated Percentage of such Excess Loss shall be allocated among the Classes of Subordinated Certificates, pro rata, based on each Class’ share of the Assumed Balance of the related Loan Group immediately prior to the related Distribution Date; provided, however, on any Distribution Date after a Senior Termination Date for a Senior Certificate Group, such Excess Losses on the Mortgage Loans in the related Loan Group shall be allocated to the Senior Certificates (other than the Notional Amount Certificates) and the Subordinated Certificates on the basis of their respective Class Certificate Balances immediately prior to such Distribution Date; provided further, however, on any Distribution Date on and after the Senior Credit Support Depletion Date, any Excess Loss shall be allocated, pro rata, among the Classes of Senior Certificates (other than the Notional Amount Certificates) based on their respective Class Certificate Balances immediately prior to the related Distribution Date.

(b) The Class Certificate Balance of the Class of Subordinated Certificates then outstanding with the highest numerical Class designation shall be reduced on each Distribution Date by the amount, if any, by which the aggregate Class Certificate Balance of all outstanding Classes of Certificates (after giving effect to the distribution of principal and the allocation of Realized Losses on such Distribution Date) exceeds the aggregate Stated Principal Balance of the Mortgage Loans as of the Due Date in the month of such Distribution Date (after giving effect to Principal Prepayments in the Prepayment Period related to such Due Date).

(c) Any Realized Loss allocated to a Class of Certificates or any reduction in the Class Certificate Balance of a Class of Certificates pursuant to Section 4.05(a) or (b) shall be allocated among the Certificates of such Class in proportion to their respective Certificate Balances.

(d) Any allocation of Realized Losses to a Certificate or any reduction in the Certificate Balance of a Certificate pursuant to Section 4.05(a) or (b) shall be accomplished by reducing the Certificate Balance thereof immediately following the distributions made on the related Distribution Date in accordance with the definition of Certificate Balance.

ARTICLE FIVE

THE CERTIFICATES

Section 5.01 The Certificates.

The Certificates shall be substantially in the forms attached hereto as exhibits. The Certificates shall be issuable in registered form, in the minimum denominations, integral multiples in excess thereof (except that one Certificate in each Class may be issued in a different amount which must exceed the applicable minimum denomination) and aggregate denominations per Class set forth in the Preliminary Statement.

Subject to Section 9.02 respecting the final distribution on the Certificates, on each Distribution Date the Trustee shall make distributions to each Certificateholder of record on the preceding Record Date either (x) by wire transfer in immediately available funds to the account of such holder at a bank or other entity having appropriate facilities therefor, if such Holder has so notified the Trustee at least five Business Days before the related Record Date or (y) by check mailed by first class mail to such Certificateholder at the address of such holder appearing in the Certificate Register.

The Trustee shall execute the Certificates by the manual or facsimile signature of an authorized officer. Certificates bearing the manual or facsimile signatures of individuals who were, at the time such signatures were affixed, authorized to sign on behalf of the Trustee shall bind the Trustee, notwithstanding that such individuals or any of them have ceased to be so authorized before the countersignature and delivery of any such Certificates or did not hold such offices at the date of such Certificate. No Certificate shall be entitled to any benefit under this Agreement, or be valid for any purpose, unless countersigned by the Trustee by manual signature, and such countersignature upon any Certificate shall be conclusive evidence, and the only evidence, that such Certificate has been duly executed and delivered hereunder. All Certificates shall be dated the date of their countersignature. On the Closing Date, the Trustee shall countersign the Certificates to be issued at the direction of the Depositor, or any affiliate thereof.

The Depositor shall provide the Trustee, on a continuous basis with an adequate inventory of Certificates to facilitate transfers.

Section 5.02 Certificate Register; Registration of Transfer and Exchange of Certificates.

(a) The Trustee shall maintain, in accordance with Section 5.06, a Certificate Register for the Trust Fund in which, subject to subsections (b) and (c) below and to such reasonable regulations as it may prescribe, the Trustee shall provide for the registration of Certificates and of transfers and exchanges of Certificates as herein provided. Upon surrender for registration of transfer of any Certificate, the Trustee shall execute and deliver, in the name of the designated transferee or transferees, one or more new Certificates of the same Class and aggregate Percentage Interest.

At the option of a Certificateholder, Certificates may be exchanged for other Certificates of the same Class in authorized denominations and evidencing the same aggregate Percentage Interest upon surrender of the Certificates to be exchanged at the office or agency of the Trustee. Whenever any Certificates are so surrendered for exchange, the Trustee shall execute, authenticate, and deliver the Certificates that the Certificateholder making the exchange is entitled to receive. A written instrument of transfer in form satisfactory to the Trustee duly executed by the holder of a Certificate or his attorney duly authorized in writing shall accompany every Certificate presented or surrendered for registration of transfer or exchange.

No service charge to the Certificateholders shall be made for any registration of transfer or exchange of Certificates, but payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any transfer or exchange of Certificates may be required.

All Certificates surrendered for registration of transfer or exchange shall be cancelled and subsequently destroyed by the Trustee in accordance with the Trustee’s customary procedures.

(b) No transfer of a Private Certificate shall be made unless such transfer is made pursuant to an effective registration statement under the Securities Act and any applicable state securities laws or is exempt from the registration requirements under the Securities Act and such state securities laws. If a transfer is to be made in reliance on an exemption from the Securities Act and such state securities laws, to assure compliance with the Securities Act and such state securities laws, the Certificateholder desiring to effect such transfer and such Certificateholder’s prospective transferee shall each certify to the Trustee in writing the facts surrounding the transfer in substantially the form set forth in Exhibit J (the “Transferor Certificate”) and deliver to the Trustee either (i) a letter in substantially the form of either Exhibit K (the “Investment Letter”) or Exhibit L (the “Rule 144A Letter”) or (ii) at the expense of the transferor, an Opinion of Counsel that the transfer may be made without registration under the Securities Act. The Depositor shall provide to any Holder of a Private Certificate and any prospective transferee designated by that Holder, information regarding the related Certificates and the Mortgage Loans and any other information necessary to satisfy the condition to eligibility in Rule 144A(d)(4) for transfer of the Certificate without registration thereof under the Securities Act pursuant to the registration exemption provided by Rule 144A. The Trustee and the Servicer shall cooperate with the Depositor in providing the Rule 144A information referenced in the preceding sentence, including providing to the Depositor such information regarding the Certificates, the Mortgage Loans, and other matters regarding the Trust Fund as the Depositor reasonably requests to meet its obligation under the preceding sentence. Each Holder of a Private Certificate desiring to effect a transfer shall, and does hereby agree to, indemnify the Trustee, the Depositor, the Seller, and the Servicer against any liability that may result if the transfer is not so exempt or is not made in accordance with such federal and state laws.

No transfer of an ERISA-Restricted Certificate shall be made unless the Trustee shall have received either (i) a representation from the transferee of such Certificate acceptable to and in form and substance satisfactory to the Trustee (if the Certificate is a Private Certificate, the requirement is satisfied only by the Trustee’s receipt of a representation letter from the transferee substantially in the form of Exhibit K or Exhibit L, and if the Certificate is a Residual Certificate, the requirement is satisfied only by the Trustee’s receipt of a representation letter from the transferee substantially in the form of Exhibit I), to the effect that (x) the transferee is not an employee benefit plan or arrangement subject to section 406 of ERISA or a plan subject to section 4975 of the Code, or a person acting on behalf of any such plan or arrangement or using the assets of any such plan or arrangement to effect the transfer, or (y) if the ERISA-Restricted Certificate has been the subject of an ERISA-Qualifying Underwriting, a representation that the transferee is an insurance company that is purchasing such Certificate with funds contained in an “insurance company general account” (as such term is defined in Section V(e) of Prohibited Transaction Class Exemption 95-60 (“PTCE 95-60”) and that the purchase and holding of such Certificate satisfies the requirements for exemptive relief under Sections I and III of PTCE 95-60, or (ii) in the case of any ERISA-Restricted Certificate presented for registration in the name of an employee benefit plan subject to ERISA, or a plan or arrangement subject to section 4975 of the Code (or comparable provisions of any subsequent enactments), or a trustee of any such plan or any other person acting on behalf of any such plan or arrangement or using such plan’s or arrangement’s assets, an Opinion of Counsel satisfactory to the Trustee, which Opinion of Counsel shall not be an expense of the Trustee, the Servicer or the Trust Fund, addressed to the Trustee and the Servicer, to the effect that the purchase and holding of such ERISA-Restricted Certificate will not result in a non-exempt prohibited transaction under ERISA or section 4975 of the Code and will not subject the Trustee or the Servicer to any obligation in addition to those expressly undertaken in this Agreement or to any liability. For purposes of the preceding sentence, with respect to an ERISA-Restricted Certificate that is not a Residual Certificate, if the appropriate representation letter or Opinion of Counsel referred to in the preceding sentence is not furnished, the representation in clause (i) above, shall be deemed to have been made to the Trustee by the transferee’s (including an initial acquirer’s) acceptance of the ERISA-Restricted Certificates. If the representation is violated, or any attempt is made to transfer to a plan or arrangement subject to section 406 of ERISA or a plan subject to section 4975 of the Code, or a person acting on behalf of any such plan or arrangement or using the assets of any such plan or arrangement, without the Opinion of Counsel described above, the attempted transfer or acquisition shall be void.

To the extent permitted under applicable law (including ERISA), the Trustee shall be under no liability to any Person for any registration of transfer of any ERISA-Restricted Certificate that is in fact not permitted by this Section 5.02(b) or for making any payments due on such Certificate to the Holder thereof or taking any other action with respect to such Holder under this Agreement so long as the transfer was registered by the Trustee in accordance with the foregoing requirements.

(c) Each Person who has or who acquires any Ownership Interest in a Residual Certificate shall be deemed by the acceptance or acquisition of such Ownership Interest to have agreed to be bound by the following provisions, and the rights of each Person acquiring any Ownership Interest in a Residual Certificate are expressly subject to the following provisions:

(i) Each Person holding or acquiring any Ownership Interest in a Residual Certificate shall be a Permitted Transferee and shall promptly notify the Trustee of any change or impending change in its status as a Permitted Transferee.

(ii) No Ownership Interest in a Residual Certificate may be registered on the Closing Date or thereafter transferred, and the Trustee shall not register the Transfer of any Residual Certificate unless, in addition to the certificates required to be delivered to the Trustee under subparagraph (b) above, the Trustee shall have been furnished with an affidavit (a “Transfer Affidavit”) of the initial owner or the proposed transferee in the form of Exhibit I.

(iii) Each Person holding or acquiring any Ownership Interest in a Residual Certificate shall agree (A) to obtain a Transfer Affidavit from any other Person to whom such Person attempts to Transfer its Ownership Interest in a Residual Certificate, (B) to obtain a Transfer Affidavit from any Person for whom such Person is acting as nominee, trustee or agent in connection with any Transfer of a Residual Certificate and (C) not to Transfer its Ownership Interest in a Residual Certificate or to cause the Transfer of an Ownership Interest in a Residual Certificate to any other Person if it has actual knowledge that such Person is not a Permitted Transferee.

(iv) Any attempted or purported Transfer of any Ownership Interest in a Residual Certificate in violation of this Section 5.02(c) shall be absolutely null and void and shall vest no rights in the purported Transferee. If any purported transferee shall become a Holder of a Residual Certificate in violation of this Section 5.02(c), then the last preceding Permitted Transferee shall be restored to all rights as Holder thereof retroactive to the date of registration of Transfer of such Residual Certificate. The Trustee shall be under no liability to any Person for any registration of Transfer of a Residual Certificate that is in fact not permitted by Section 5.02(b) and this Section 5.02(c) or for making any payments due on such Certificate to the Holder thereof or taking any other action with respect to such Holder under this Agreement so long as the Transfer was registered after receipt of the related Transfer Affidavit, Transferor Certificate and either the Rule 144A Letter or the Investment Letter. The Trustee shall be entitled but not obligated to recover from any Holder of a Residual Certificate that was in fact not a Permitted Transferee at the time it became a Holder or, at such subsequent time as it became other than a Permitted Transferee, all payments made on such Residual Certificate at and after either such time. Any such payments so recovered by the Trustee shall be paid and delivered by the Trustee to the last preceding Permitted Transferee of such Certificate.

(v) The Depositor shall use its best efforts to make available, upon receipt of written request from the Trustee, all information necessary to compute any tax imposed under section 860E(e) of the Code as a result of a Transfer of an Ownership Interest in a Residual Certificate to any Holder who is not a Permitted Transferee.

The restrictions on Transfers of a Residual Certificate set forth in this Section 5.02(c) shall cease to apply (and the applicable portions of the legend on a Residual Certificate may be deleted) with respect to Transfers occurring after delivery to the Trustee of an Opinion of Counsel, which Opinion of Counsel shall not be an expense of the Trust Fund, the Trustee, the Seller or the Servicer, to the effect that the elimination of such restrictions will not cause any REMIC created under this Agreement to fail to qualify as a REMIC at any time that the Certificates are outstanding or result in the imposition of any tax on the Trust Fund, a Certificateholder or another Person. Each Person holding or acquiring any Ownership Interest in a Residual Certificate hereby consents to any amendment of this Agreement which, based on an Opinion of Counsel furnished to the Trustee, is reasonably necessary (a) to ensure that the record ownership of, or any beneficial interest in, a Residual Certificate is not transferred, directly or indirectly, to a Person that is not a Permitted Transferee and (b) to provide for a means to compel the Transfer of a Residual Certificate which is held by a Person that is not a Permitted Transferee to a Holder that is a Permitted Transferee.

(d) The preparation and delivery of all certificates and opinions referred to above in this Section 5.02 in connection with transfer shall be at the expense of the parties to such transfers.

(e) Except as provided below, the Book-Entry Certificates shall at all times remain registered in the name of the Depository or its nominee and at all times: (i) registration of the Certificates may not be transferred by the Trustee except to another Depository; (ii) the Depository shall maintain book-entry records with respect to the Certificate Owners and with respect to ownership and transfers of such Book-Entry Certificates; (iii) ownership and transfers of registration of the Book-Entry Certificates on the books of the Depository shall be governed by applicable rules established by the Depository; (iv) the Depository may collect its usual and customary fees, charges and expenses from its Depository Participants; (v) the Trustee shall deal with the Depository, Depository Participants and Indirect Participants as representatives of the Certificate Owners of the Book-Entry Certificates for purposes of exercising the rights of holders under this Agreement, and requests and directions for and votes of such representatives shall not be deemed to be inconsistent if they are made with respect to different Certificate Owners; and (vi) the Trustee may rely and shall be fully protected in relying upon information furnished by the Depository with respect to its Depository Participants and furnished by the Depository Participants with respect to Indirect Participants and persons shown on the books of such Indirect Participants as direct or indirect Certificate Owners.

All transfers by Certificate Owners of Book-Entry Certificates shall be made in accordance with the procedures established by the Depository Participant or brokerage firm representing the Certificate Owner. Each Depository Participant shall only transfer Book-Entry Certificates of Certificate Owners it represents or of brokerage firms for which it acts as agent in accordance with the Depository’s normal procedures.

If (x) (i) the Depository or the Depositor advises the Trustee in writing that the Depository is no longer willing or able to properly discharge its responsibilities as Depository, and (ii) the Trustee or the Depositor is unable to locate a qualified successor or (y) after the occurrence of an Event of Default, Certificate Owners representing at least 51% of the Certificate Balance of the Book-Entry Certificates together advise the Trustee and the Depository through the Depository Participants in writing that the continuation of a book-entry system through the Depository is no longer in the best interests of the Certificate Owners, the Trustee shall notify all Certificate Owners, through the Depository, of the occurrence of any such event and of the availability of definitive, fully-registered Certificates (the “Definitive Certificates”) to Certificate Owners requesting the same. Upon surrender to the Trustee of the related Class of Certificates by the Depository, accompanied by the instructions from the Depository for registration, the Trustee shall issue the Definitive Certificates. Neither the Servicer, the Depositor nor the Trustee shall be liable for any delay in delivery of such instruction and each may conclusively rely on, and shall be protected in relying on, such instructions. The Servicer shall provide the Trustee with an adequate inventory of certificates to facilitate the issuance and transfer of Definitive Certificates. Upon the issuance of Definitive Certificates all references herein to obligations imposed upon or to be performed by the Depository shall be deemed to be imposed upon and performed by the Trustee, to the extent applicable with respect to such Definitive Certificates and the Trustee shall recognize the Holders of the Definitive Certificates as Certificateholders hereunder; provided that the Trustee shall not by virtue of its assumption of such obligations become liable to any party for any act or failure to act of the Depository.

Section 5.03 Mutilated, Destroyed, Lost or Stolen Certificates.

If (a) any mutilated Certificate is surrendered to the Trustee, or (b) the Trustee receives evidence to its satisfaction of the destruction, loss, or theft of any Certificate and the Servicer and the Trustee receive the security or indemnity required by them to hold each of them harmless, then, in the absence of notice to the Trustee that the Certificate has been acquired by a Protected Purchaser, and if the requirements of Section 8-406 of the UCC are met and subject to Section 8-405 of the UCC, the Trustee shall execute, countersign, and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost, or stolen Certificate, a new Certificate of like Class, tenor, and Percentage Interest. In connection with the issuance of any new Certificate under this Section 5.03, the Trustee may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith. Any replacement Certificate issued pursuant to this Section 5.03 shall constitute complete and indefeasible evidence of ownership, as if originally issued, whether or not the lost, stolen, or destroyed Certificate is found at any time.

Section 5.04 Persons Deemed Owners.

The Servicer, the Trustee, and any agent of the Servicer or the Trustee may treat the Person in whose name any Certificate is registered as the owner of such Certificate for the purpose of receiving distributions as provided in this Agreement and for all other purposes whatsoever, and neither the Servicer, the Trustee nor any agent of the Servicer or the Trustee shall be affected by any notice to the contrary.

Section 5.05 Access to List of Certificateholders’ Names and Addresses.

If three or more Certificateholders and/or Certificate Owners (a) request such information in writing from the Trustee, (b) state that such Certificateholders and/or Certificate Owners desire to communicate with other Certificateholders and/or Certificate Owners with respect to their rights under this Agreement or under the Certificates, and (c) provide a copy of the communication which such Certificateholders and/or Certificate Owners propose to transmit, or if the Depositor or Servicer shall request such information in writing from the Trustee, then the Trustee shall, within ten Business Days after the receipt of such request, provide the Depositor, the Servicer or such Certificateholders and/or Certificate Owners at such recipients’ expense the most recent list of the Certificateholders of such Trust Fund held by the Trustee. The Depositor and every Certificateholder and/or Certificate Owner, by receiving and holding a Certificate, agree that the Trustee shall not be held accountable because of the disclosure of any such information as to the list of the Certificateholders hereunder, regardless of the source from which such information was derived.

Section 5.06 Maintenance of Office or Agency.

The Certificate Registrar will maintain at its expense an office or offices or agency or agencies in the United States located at DB Services Tennessee, 000 Xxxxxxxxx Xxxx Xx., Xxxxxxxxx, XX 00000-0000, Attention: Transfer Unit, where Certificates may be surrendered for registration of transfer or exchange. The Certificate Registrar will give prompt written notice to the Certificateholders and to the Trustee (if other than the Certificate Registrar) of any change in such location of any such office or agency.

Any Person into which the Depositor or the Servicer may be merged or consolidated, or any Person resulting from any merger or consolidation to which the Depositor or the Servicer shall be a party, or any person succeeding to the business of the Depositor or the Servicer, shall be the successor of the Depositor or the Servicer, as the case may be, hereunder, without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding; provided, however, that the successor or surviving Person to the Servicer shall be qualified to sell mortgage loans to, and to service mortgage loans on behalf of, FNMA or FHLMC.

As a condition to the effectiveness of any merger or consolidation, at least 15 calendar days prior to the effective date of any merger or consolidation of the Servicer, the Servicer shall provide (x) written notice to the Depositor of any successor pursuant to this Section and (y) in writing and in form and substance reasonably satisfactory to the Depositor, all information reasonably requested by the Depositor in order to comply with its reporting obligation under Item 6.02 of Form 8-K with respect to a replacement Servicer.

None of the Depositor, the Seller, the Servicer or any of the directors, officers, employees or agents of the Depositor, the Seller or the Servicer shall be under any liability to the Certificateholders for any action taken or for refraining from the taking of any action in good faith pursuant to this Agreement, or for errors in judgment; provided, however, that this provision shall not protect the Depositor, the Seller, the Servicer or any such Person against any breach of representations or warranties made by it herein or protect the Depositor, the Seller, the Servicer or any such Person from any liability which would otherwise be imposed by reasons of willful misfeasance, bad faith or gross negligence in the performance of duties or because of reckless disregard of obligations and duties hereunder.

Any such determination under clause (b) permitting the resignation of the Servicer shall be evidenced by an Opinion of Counsel to such effect delivered to the Trustee. No such resignation shall become effective until the Trustee or a successor servicer shall have assumed the Servicer’s responsibilities, duties, liabilities and obligations under this Agreement and the Depositor shall have received the information described in the following sentence. As a condition to the effectiveness of any such resignation, at least 15 calendar days prior to the effective date of such resignation, the Servicer shall provide (x) written notice to the Depositor of any successor pursuant to this Section and (y) in writing and in form and substance reasonably satisfactory to the Depositor, all information reasonably requested by the Depositor in order to comply with its reporting obligation under Item 6.02 of Form 8-K with respect to the resignation of the Servicer.

ARTICLE SEVEN

DEFAULT

Section 7.01 Events of Default.

“Event of Default,” wherever used in this Agreement, means any one of the following events:

(a) any failure by the Servicer to deposit in the Certificate Account or remit to the Trustee any payment required to be made by it under this Agreement, which failure continues unremedied for five days after the date on which written notice of the failure has been given to the Servicer by the Trustee or the Depositor or to the Servicer and the Trustee by the Holders of Certificates of any Class evidencing not less than 25% of the aggregate Percentage Interests of the Class; or

(b) any failure by the Servicer to observe or perform in any material respect any other of the covenants or agreements on the part of the Servicer contained in this Agreement (except with respect to a failure related to a Limited Exchange Act Reporting Obligation), which failure materially affects the rights of Certificateholders and continues unremedied for a period of 60 days after the date on which written notice of such failure shall have been given to the Servicer by the Trustee or the Depositor, or to the Servicer and the Trustee by the Holders of Certificates of any Class evidencing not less than 25% of the Percentage Interests of the Class; provided that the sixty-day cure period shall not apply to the initial delivery of the Mortgage File for Delay Delivery Mortgage Loans nor the failure to repurchase or substitute in lieu thereof; or

(c) a decree or order of a court or agency or supervisory authority having jurisdiction in the premises for the appointment of a receiver, conservator or liquidator in any insolvency, readjustment of debt, marshalling of assets and liabilities or similar proceedings, or for the winding-up or liquidation of its affairs, shall have been entered against the Servicer and such decree or order shall have remained in force undischarged or unstayed for a period of 60 consecutive days; or

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

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

(f) the Servicer shall fail (i) to make an Advance on the Servicer Advance Date or (ii) to reimburse in full the Trustee within two days of the Servicer Advance Date for any Advance made by the Trustee pursuant to Section 4.01(b).

If an Event of Default described in clauses (a) through (f) of this Section 7.01 occurs, then, and in each and every such case, so long as such Event of Default shall not have been remedied, the Trustee may, or at the direction of the Holders of Certificates of any Class evidencing not less than 66 2/3% of the Percentage Interests of the Class, the Trustee shall by notice in writing to the Servicer (with a copy to each Rating Agency), terminate all of the rights and obligations of the Servicer under this Agreement and in the Mortgage Loans and the proceeds thereof, other than its rights as a Certificateholder hereunder. In addition, if during the period that the Depositor is required to file Exchange Act Reports with respect to the Trust Fund, the Servicer shall fail to observe or perform any of the obligations that constitute a Limited Exchange Act Reporting Obligation or the obligations set forth in Section 3.17(a) or Section 11.07(a)(i) and (ii), and such failure continues for the lesser of 10 calendar days or such period in which the applicable Exchange Act Report can be filed timely (without taking into account any extensions), so long as such failure shall not have been remedied, the Trustee shall, but only at the direction of the Depositor, terminate all of the rights and obligations of the Servicer under this Agreement and in and to the Mortgage Loans and the proceeds thereof, other than its rights as a Certificateholder hereunder. The Depositor shall not be entitled to terminate the rights and obligations of the Servicer if a failure of the Servicer to identify a Subcontractor “participating in the servicing function” within the meaning of Item 1122 of Regulation AB was attributable solely to the role or functions of such Subcontractor with respect to mortgage loans other than the Mortgage Loans.

On and after the receipt by the Servicer of such written notice, all authority and power of the Servicer hereunder, whether with respect to the Mortgage Loans or otherwise, shall pass to and be vested in the Trustee. The Trustee shall make any Advance that the Servicer failed to make subject to Section 3.05, whether or not the obligations of the Servicer have been terminated pursuant to this Section. The Trustee is hereby authorized and empowered to execute and deliver, on behalf of the Servicer, as attorney-in-fact or otherwise, any documents and other instruments, and to do or accomplish all other acts or things necessary or appropriate to effect the purposes of such notice of termination, whether to complete the transfer and endorsement or assignment of the Mortgage Loans and related documents, or otherwise. Unless expressly provided in such written notice, no such termination shall affect any obligation of the Servicer to pay amounts owed pursuant to Article VIII. The Servicer agrees to cooperate with the Trustee in effecting the termination of the Servicer’s responsibilities and rights hereunder, including the transfer to the Trustee of all cash amounts which shall at the time be credited to the Certificate Account, or thereafter be received with respect to the Mortgage Loans. If the Servicer fails to make any Advance required under Section 4.01 of this Agreement, thereby triggering an Event of Default described in clause (f) of this Section 7.01, the Trustee shall make such Advance on that Distribution Date.

Notwithstanding any termination of the activities of the Servicer under this Agreement, the Servicer shall be entitled to receive, out of any late collection of a Scheduled Payment on a Mortgage Loan which was due before the notice terminating such Servicer’s rights and obligations as Servicer hereunder and received after such notice, that portion thereof to which such Servicer would have been entitled pursuant to Sections 3.09(a)(i) through (viii), and any other amounts payable to such Servicer hereunder the entitlement to which arose before the termination of its activities hereunder.

If the Servicer is terminated, the Trustee shall provide the Depositor in writing and in form and substance reasonably satisfactory to the Depositor, all information reasonably requested by the Depositor in order to comply with its reporting obligation under Item 6.02 of Form 8-K with respect to a successor servicer in the event the Trustee should succeed to the duties of the Servicer as set forth herein.

Section 7.02 Trustee to Act; Appointment of Successor.

On and after the time the Servicer receives a notice of termination pursuant to Section 7.01, the Trustee shall, subject to and to the extent provided in Section 3.05, be the successor to the Servicer in its capacity as servicer under this Agreement and the transactions set forth or provided for herein and shall be subject to all the responsibilities, duties and liabilities relating thereto placed on the Servicer by the terms hereof and applicable law including the obligation to make Advances pursuant to Section 4.01. As compensation therefor, the Trustee shall be entitled to all funds relating to the Mortgage Loans that the Servicer would have been entitled to charge to the Certificate Account or Distribution Account if the Servicer had continued to act hereunder, including, if the Servicer was receiving the Servicing Fee, the Servicing Fee. Notwithstanding the foregoing, if the Trustee has become the successor to the Servicer in accordance with Section 7.01, the Trustee may, if it shall be unwilling to so act, or shall, if it is prohibited by applicable law from making Advances pursuant to Section 4.01 or if it is otherwise unable to so act, appoint, or petition a court of competent jurisdiction to appoint, any established mortgage loan servicing institution the appointment of which does not adversely affect the then current rating of the Certificates by each Rating Agency, as the successor to the Servicer hereunder in the assumption of all or any part of the responsibilities, duties or liabilities of the Servicer hereunder. Any successor to the Servicer shall be an institution which is a FNMA and FHLMC approved seller/servicer in good standing, which has a net worth of at least $15,000,000, which is willing to service the Mortgage Loans and which executes and delivers to the Depositor and the Trustee an agreement accepting such delegation and assignment, containing an assumption by such Person of the rights, powers, duties, responsibilities, obligations and liabilities of the Servicer (other than liabilities of the Servicer under Section 6.03 incurred before termination of the Servicer under Section 7.01), with like effect as if originally named as a party to this Agreement; provided that each Rating Agency acknowledges that its rating of the Certificates in effect immediately before such assignment and delegation will not be qualified or reduced as a result of such assignment and delegation. Pending appointment of a successor to the Servicer hereunder, the Trustee shall act in such capacity as provided above, subject to section 3.03 and unless prohibited by law. In connection with such appointment and assumption, the Trustee may make such arrangements for the compensation of such successor out of payments on Mortgage Loans as it and such successor shall agree; provided, however, that in no case shall the rate of such compensation exceed the Servicing Fee Rate. The Trustee and such successor shall take such action, consistent with this Agreement, as shall be necessary to effectuate any such succession. Neither the Trustee nor any other successor servicer shall be deemed to be in default hereunder because of any failure to make, or any delay in making, any distribution hereunder or any portion thereof or any failure to perform, or any delay in performing, any duties or responsibilities hereunder, in either case caused by the failure of the Servicer to deliver or provide, or any delay in delivering or providing, any cash, information, documents or records to it.

In connection with the termination or resignation of the Servicer hereunder, either (i) the successor Servicer, including the Trustee if the Trustee is acting as successor Servicer, shall represent and warrant that it is a member of MERS in good standing and shall agree to comply in all material respects with the rules and procedures of MERS in connection with the servicing of the Mortgage Loans that are registered with MERS, or (ii) the predecessor Servicer shall cooperate with the successor Servicer either (x) in causing MERS to execute and deliver an assignment of Mortgage in recordable form to transfer the Mortgage from MERS to the Trustee and to execute and deliver such other notices, documents and other instruments as may be necessary or desirable to effect a transfer of such Mortgage Loan or servicing of such Mortgage Loan on the MERS® System to the successor Servicer or (y) in causing MERS to designate on the MERS® System the successor Servicer as the servicer of such Mortgage Loan. The predecessor Servicer shall file or cause to be filed any such assignment in the appropriate recording office. The successor Servicer shall cause such assignment to be delivered to the Trustee promptly upon receipt of the original with evidence of recording thereon or a copy certified by the public recording office in which such assignment was recorded.

Any successor to the Servicer as servicer shall give notice to the Mortgagors of such change of servicer and shall, during the term of its service as servicer, maintain in force the policy or policies that the Servicer is required to maintain pursuant to this Agreement.

Section 7.03 Notification to Certificateholders.

(a) Upon any termination of or appointment of a successor to the Servicer, the Trustee shall give prompt written notice thereof to Certificateholders and to each Rating Agency.

(b) Within 60 days after the occurrence of any Event of Default, the Trustee shall transmit by mail to all Certificateholders and each Rating Agency notice of each such Event of Default hereunder known to the Trustee, unless such Event of Default shall have been cured or waived.

ARTICLE EIGHT

CONCERNING THE TRUSTEE

Section 8.01 Duties of the Trustee.

The Trustee, before the occurrence of an Event of Default and after the curing of all Events of Default that may have occurred, shall undertake to perform such duties and only such duties as are specifically set forth in this Agreement. In case an Event of Default has occurred and remains uncured, the Trustee shall exercise such of the rights and powers vested in it by this Agreement, and use the same degree of care and skill in their exercise as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs.

The Trustee, upon receipt of all resolutions, certificates, statements, opinions, reports, documents, orders or other instruments furnished to the Trustee that are specifically required to be furnished pursuant to any provision of this Agreement shall examine them to determine whether they are in the form required by this Agreement. The Trustee shall not be responsible for the accuracy or content of any such resolution, certificate, statement, opinion, report, document, order, or other instrument.

No provision of this Agreement shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act or its own willful misconduct; provided, however, that, unless an Event of Default known to the Trustee has occurred and is continuing,

(a) the duties and obligations of the Trustee shall be determined solely by the express provisions of this Agreement, the Trustee shall not be liable except for the performance of the duties and obligations specifically set forth in this Agreement, no implied covenants or obligations shall be read into this Agreement against the Trustee, and the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of this Agreement which it believed in good faith to be genuine and to have been duly executed by the proper authorities respecting any matters arising hereunder;

(b) the Trustee shall not be liable for an error of judgment made in good faith by a Responsible Officer or Responsible Officers of the Trustee, unless it is finally proven that the Trustee was negligent in ascertaining the pertinent facts; and

(c) the Trustee shall not be liable with respect to any action taken, suffered, or omitted to be taken by it in good faith in accordance with the direction of Holders of Certificates evidencing not less than 25% of the Voting Rights of Certificates relating to the time, method, and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee under this Agreement. As long as any Voting Rights are held by parties other than the Seller, its Affiliates, or its agents, Voting Rights of Certificates held by the Seller, its Affiliates or its agents as the Seller shall certify to the Trustee upon any entity obtaining such ownership, will be excluded from participating in such voting arrangements, and excluded from determining the 25% threshold.

Section 8.02 Certain Matters Affecting the Trustee.

Except as otherwise provided in Section 8.01:

(a) the Trustee may request and rely upon and shall be protected in acting or refraining from acting upon any resolution, Officer’s Certificate, certificate of auditors or any other certificate, statement, instrument, opinion, report, notice, request, consent, order, appraisal, bond or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties and the Trustee shall have no responsibility to ascertain or confirm the genuineness of any signature of any such party or parties;

(b) the Trustee may consult with counsel, financial advisers or accountants and the advice of any such counsel, financial advisers or accountants and any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken or suffered or omitted by it hereunder in good faith and in accordance with such Opinion of Counsel;

(e) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents, accountants or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agents, accountants or attorneys appointed with due care by it hereunder;

(f) the Trustee shall not be required to risk or expend its own funds or otherwise incur any financial liability in the performance of any of its duties or in the exercise of any of its rights or powers hereunder if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not assured to it;

(g) the Trustee shall not be liable for any loss on any investment of funds pursuant to this Agreement (other than as issuer of the investment security);

(h) the Trustee shall not be deemed to have knowledge of an Event of Default until a Responsible Officer of the Trustee shall have received written notice thereof;

(i) the Trustee shall be under no obligation to exercise any of the trusts, rights or powers vested in it by this Agreement or to institute, conduct or defend any litigation hereunder or in relation hereto at the request, order or direction of any of the Certificateholders, pursuant to this Agreement, unless such Certificateholders shall have offered to the Trustee reasonable security or indemnity satisfactory to the Trustee against the costs, expenses and liabilities which may be incurred therein or thereby;

(j) the Trustee or its Affiliates are permitted to receive additional compensation that could be deemed to be in the Trustee’s economic self-interest for (i) serving as investment adviser, administrator, shareholder servicing agent, custodian or sub-custodian with respect to certain of the Permitted Investments, (ii) using Affiliates to effect transactions in certain Permitted Investments and (iii) effecting transactions in certain Permitted Investments. The Trustee does not guarantee the performance of any Permitted Investment; and

(k) the Trustee shall not knowingly take any action that would cause the Trust Fund to fail to qualify as a qualifying special purpose entity.

In order to comply with laws, rules, regulations and executive orders in effect from time to time applicable to banking institutions, including those relating to the funding of terrorist activities and money laundering ("Applicable Law"), the Trustee is required to obtain, verify and record certain information relating to individuals and entities which maintain a business relationship with the Trustee. Accordingly, each of the parties agrees to provide to the Trustee upon its request from time to time such identifying information and documentation as may be available for such party in order to enable the Trustee to comply with Applicable Law.

Section 8.03 Trustee Not Liable for Certificates or Mortgage Loans.

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

Except as provided in Section 2.01(c), the Trustee shall have no responsibility for filing or recording any financing or continuation statement in any public office at any time or to otherwise perfect or maintain the perfection of any security interest or lien granted to it hereunder (unless the Trustee shall have become the successor Servicer). The Trustee makes no representations as to the validity or sufficiency of this Agreement or of the Certificates or of any Mortgage Loan or related document or of MERS or the MERS® System other than with respect to the Trustee’s execution and counter-signature of the Certificates.

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

Section 8.04 Trustee May Own Certificates.

The Trustee in its individual or any other capacity may become the owner or pledgee of Certificates with the same rights as it would have if it were not the Trustee.

Section 8.05 Trustee’s Fees and Expenses.

As compensation for its activities under this Agreement, on each Distribution Date the Trustee may withdraw from the Distribution Account the Trustee Fee for that Distribution Date. The Trustee and any director, officer, employee, or agent of the Trustee shall be indemnified by the Servicer against any loss, liability, or expense (including reasonable attorney’s fees) resulting from any error in any tax or information return prepared by the Servicer or incurred in connection with any claim or legal action relating to (a) this Agreement, (b) the Certificates, or (c) the performance of any of the Trustee’s duties under this Agreement, other than any loss, liability or expense incurred because of willful misfeasance, bad faith or negligence in the performance of any of the Trustee’s duties hereunder or incurred by reason of any action of the Trustee taken at the direction of the Certificateholders under this Agreement. This indemnity shall survive the termination of this Agreement or the resignation or removal of the Trustee under this Agreement. Without limiting the foregoing, except as otherwise agreed upon in writing by the Depositor and the Trustee, and except for any expense, disbursement, or advance arising from the Trustee’s negligence, bad faith, or willful misconduct, the Servicer shall pay or reimburse the Trustee, for all reasonable expenses, disbursements, and advances incurred or made by the Trustee in accordance with this Agreement with respect to

(A) the reasonable compensation, expenses, and disbursements of its counsel not associated with the closing of the issuance of the Certificates, and

(B) the reasonable compensation, expenses, and disbursements of any accountant, engineer, or appraiser that is not regularly employed by the Trustee, to the extent that the Trustee must engage them to perform services under this Agreement.

Section 8.06 Eligibility Requirements for the Trustee.

The Trustee hereunder shall at all times be a corporation or association organized and doing business under the laws of a state or the United States of America, authorized under such laws to exercise corporate trust powers, having a combined capital and surplus of at least $50,000,000, subject to supervision or examination by federal or state authority and with a credit rating which would not cause either of the Rating Agencies to reduce their respective then current ratings of the Certificates (or having provided such security from time to time as is sufficient to avoid such reduction) as evidenced in writing by each Rating Agency. If such corporation or association publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section 8.06 the combined capital and surplus of such corporation or association shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. In case at any time the Trustee shall cease to be eligible in accordance with this Section 8.06, the Trustee shall resign immediately in the manner and with the effect specified in Section 8.07. The entity serving as Trustee may have normal banking and trust relationships with the Depositor and its affiliates or the Servicer and its affiliates; provided, however, that such entity cannot be an affiliate of the Seller, the Depositor or the Servicer other than the Trustee in its role as successor to the Servicer.

Section 8.07 Resignation and Removal of the Trustee.

The Trustee may at any time resign and be discharged from the trusts hereby created by giving written notice of resignation to the Depositor, the Servicer, and each Rating Agency not less than 60 days before the date specified in such notice, when, subject to Section 8.08, such resignation is to take effect, and acceptance by a successor trustee in accordance with Section 8.08 meeting the qualifications set forth in Section 8.06. If no successor trustee meeting such qualifications shall have been so appointed and have accepted appointment within 30 days after the giving of such notice or resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor trustee.

As a condition to the effectiveness of any such resignation, at least 15 calendar days prior to the effective date of such resignation, the Trustee shall provide (x) written notice to the Depositor of any successor pursuant to this Section and (y) in writing and in form and substance reasonably satisfactory to the Depositor, all information reasonably requested by the Depositor in order to comply with its reporting obligation under Item 6.02 of Form 8-K with respect to the resignation of the Trustee.

If at any time (i) the Trustee shall cease to be eligible in accordance with Section 8.06 and shall fail to resign after written request thereto by the Depositor, (ii) the Trustee shall become incapable of acting, or shall be adjudged as bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, (iii)(A) a tax is imposed with respect to the Trust Fund by any state in which the Trustee or the Trust Fund is located and (B) the imposition of such tax would be avoided by the appointment of a different trustee, or (iv) during the period which the Depositor is required to file Exchange Act Reports with respect to the Trust Fund, the Trustee fails to comply with its obligations under the last sentence of Section 7.01, the preceding paragraph, Section 8.09 or Article 11 and such failure is not remedied within the lesser of 10 calendar days or such period in which the applicable Exchange Act Report can be filed timely (without taking into account any extensions), then, in the case of clauses (i) through (iii), then the Depositor or the Servicer, or in the case of clause (iv), the Depositor, may remove the Trustee and appoint a successor trustee by written instrument, in triplicate, one copy of which shall be delivered to the Trustee, one copy to the Servicer and one copy to the successor trustee.

The Holders of Certificates entitled to at least 51% of the Voting Rights may at any time remove the Trustee and appoint a successor trustee by written instrument or instruments, in triplicate, signed by such Holders or their attorneys-in-fact duly authorized, one complete set of which shall be delivered by the successor Trustee to the Servicer, one complete set to the Trustee so removed, one complete set to the successor so appointed and one complete set to the Depositor, together with a written description of the basis for such removal. As long as any Voting Rights are held by parties other than the Seller, its Affiliates, or its agents, Voting Rights of Certificates held by the Seller, its Affiliates or its agents as the Seller shall certify to the Trustee upon any such entity obtaining such ownership will be excluded from participating in such voting arrangements, and excluded from determining the 51% threshold. The successor trustee shall notify each Rating Agency of any removal of the Trustee.

Any resignation or removal of the Trustee and appointment of a successor trustee pursuant to this Section 8.07 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 8.08.

Section 8.08 Successor Trustee.

Any successor trustee appointed as provided in Section 8.07 shall execute, acknowledge and deliver to the Depositor and to its predecessor trustee and the Servicer an instrument accepting such appointment hereunder and thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become fully vested with all the rights, powers, duties and obligations of its predecessor hereunder, with the like effect as if originally named as trustee herein. The Depositor, the Servicer and the predecessor trustee shall execute and deliver such instruments and do such other things as may reasonably be required for more fully and certainly vesting and confirming in the successor trustee all such rights, powers, duties, and obligations.

No successor trustee shall accept appointment as provided in this Section 8.08 unless, at the time of its acceptance, the successor trustee is eligible under Section 8.06 and its appointment does not adversely affect the then current rating of the Certificates and has provided to the Depositor in writing and in form and substance reasonably satisfactory to the Depositor, all information reasonably requested by the Depositor in order to comply with its reporting obligation under Item 6.02 of Form 8-K with respect to a replacement Trustee.

Upon acceptance of appointment by a successor trustee as provided in this Section 8.08, the Depositor shall mail notice of the succession of such trustee hereunder to all Holders of Certificates. If the Depositor fails to mail such notice within 10 days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be mailed at the expense of the Depositor.

Section 8.09 Merger or Consolidation of the Trustee.

Any corporation into which the Trustee may be merged or converted or with which it may be consolidated or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to the business of the Trustee, shall be the successor of the Trustee hereunder, provided that such corporation shall be eligible under Section 8.06 without the execution or filing of any paper or further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding.

As a condition to the effectiveness of any merger or consolidation, at least 15 calendar days prior to the effective date of any merger or consolidation of the Trustee, the Trustee shall provide (x) written notice to the Depositor of any successor pursuant to this Section and (y) in writing and in form and substance reasonably satisfactory to the Depositor, all information reasonably requested by the Depositor in order to comply with its reporting obligation under Item 6.02 of Form 8-K with respect to a replacement Trustee.

Section 8.10 Appointment of Co-Trustee or Separate Trustee.

Notwithstanding any other provisions of this Agreement, at any time, for the purpose of meeting any legal requirements of any jurisdiction in which any part of the Trust Fund or property securing any Mortgage Note may at the time be located, the Servicer and the Trustee acting jointly shall have the power and shall execute and deliver all instruments to appoint one or more Persons approved by the Trustee to act as co-trustee or co-trustees jointly with the Trustee, or separate trustee or separate trustees, of all or any part of the Trust Fund, and to vest in such Person or Persons, in such capacity and for the benefit of the Certificateholders, such title to the Trust Fund or any part thereof, whichever is applicable, and, subject to the other provisions of this Section 8.10, such powers, duties, obligations, rights and trusts as the Servicer and the Trustee may consider appropriate. If the Servicer shall not have joined in such appointment within 15 days after the receipt by it of a request to do so, or in the case an Event of Default shall have occurred and be continuing, the Trustee alone shall have the power to make such appointment. No co-trustee or separate trustee hereunder shall be required to meet the terms of eligibility as a successor trustee under Section 8.06 and no notice to Certificateholders of the appointment of any co-trustee or separate trustee shall be required under Section 8.08.

Every separate trustee and co-trustee shall, to the extent permitted by law, be appointed and act subject to the following provisions and conditions:

(a) To the extent necessary to effectuate the purposes of this Section 8.10, all rights, powers, duties and obligations conferred or imposed upon the Trustee, except for the obligation of the Trustee under this Agreement to advance funds on behalf of the Servicer, shall be conferred or imposed upon and exercised or performed by the Trustee and such separate trustee or co-trustee jointly (it being understood that such separate trustee or co-trustee is not authorized to act separately without the Trustee joining in such act), except to the extent that under any law of any jurisdiction in which any particular act or acts are to be performed (whether as Trustee hereunder or as successor to the Servicer hereunder), the Trustee shall be incompetent or unqualified to perform such act or acts, in which event such rights, powers, duties and obligations (including the holding of title to the applicable Trust Fund or any portion thereof in any such jurisdiction) shall be exercised and performed singly by such separate trustee or co-trustee, but solely at the direction of the Trustee;

(b) No trustee hereunder shall be held personally liable because of any act or omission of any other trustee hereunder and such appointment shall not, and shall not be deemed to, constitute any such separate trustee or co-trustee as agent of the Trustee;

(d) The Servicer, and not the Trustee, shall be liable for the payment of reasonable compensation, reimbursement and indemnification to any such separate trustee or co-trustee.

Any notice, request or other writing given to the Trustee shall be deemed to have been given to each of the separate trustees and co-trustees, when and as effectively as if given to each of them. Every instrument appointing any separate trustee or co-trustee shall refer to this Agreement and the conditions of this Article VIII. Each separate trustee and co-trustee, upon its acceptance of the trusts conferred, shall be vested with the estates or property specified in its instrument of appointment, either jointly with the Trustee or separately, as may be provided therein, subject to all the provisions of this Agreement, specifically including every provision of this Agreement relating to the conduct of, affecting the liability of, or affording protection to, the Trustee. Every such instrument shall be filed with the Trustee and a copy thereof given to the Servicer and the Depositor.

Any separate trustee or co-trustee may, at any time, constitute the Trustee its agent or attorney-in-fact, with full power and authority, to the extent not prohibited by law, to do any lawful act under or in respect of this Agreement on its behalf and in its name. If any separate trustee or co-trustee shall die, become incapable of acting, resign or be removed, all of its estates, properties, rights, remedies and trusts shall vest in and be exercised by the Trustee, to the extent permitted by law, without the appointment of a new or successor trustee.

Section 8.11 Tax Matters.

It is intended that the assets with respect to which one or more REMIC elections pertaining to the Trust Fund is to be made, as set forth in the Preliminary Statement, shall constitute, and that the conduct of matters relating to such assets shall be such as to qualify such assets as, a “real estate mortgage investment conduit” as defined in and in accordance with the REMIC Provisions. In furtherance of such intention, the Trustee covenants and agrees that it shall act as agent (and the Trustee is hereby appointed to act as agent) on behalf of each REMIC created under this Agreement and that in such capacity it shall:

(a) prepare and file in a timely manner, a U.S. Real Estate Mortgage Investment Conduit Income Tax Return (Form 1066 or any successor form adopted by the Internal Revenue Service) with respect to each REMIC created hereunder and prepare and file with the Internal Revenue Service and applicable state or local tax authorities income tax or information returns for each taxable year with respect to each REMIC described in the Preliminary Statement, containing such information and at the times and in the manner as may be required by the Code or state or local tax laws, regulations, or rules, and furnish to Certificateholders the schedules, statements or information at such times and in such manner as may be required thereby;

(b) within thirty days of the Closing Date, furnish to the Internal Revenue Service, on Forms 8811 or as otherwise may be required by the Code, the name, title, address, and telephone number of the person that the holders of the Certificates may contact for tax information relating thereto, together with such additional information as may be required by such Form, and update such information at the time or times in the manner required by the Code;

(c) make an election that each REMIC created under this Agreement be treated as a REMIC on the federal tax return for its first taxable year (and, if necessary, under applicable state law);

(d) prepare and forward to the Certificateholders and to the Internal Revenue Service and, if necessary, state tax authorities, all information returns and reports as and when required to be provided to them in accordance with the REMIC Provisions, including the calculations of any original issue discount and of taxable income or net loss to the holders of the residual interests in each REMIC created hereunder using the Prepayment Assumption (as defined in the Prospectus Supplement). For purposes of calculating taxable income or net loss to the holders of the residual interests in each such REMIC, the Trustee also shall assume that the indices in respect of any adjustable rate Mortgage Loans are static until the liquidation or purchase of the Mortgage Loans in accordance with Section 9.01;

(e) provide information necessary for the computation of tax imposed on the transfer of a Residual Certificate to a Person that is not a Permitted Transferee, or an agent (including a broker, nominee or other middleman) of a Person that is not a Permitted Transferee, or a pass-through entity in which a Person that is not a Permitted Transferee is the record holder of an interest (the reasonable cost of computing and furnishing such information may be charged to the Person liable for such tax);

(f) to the extent that they are under its control, conduct matters relating to such assets at all times that any Certificates are outstanding so as to maintain the status as any REMIC created under this Agreement under the REMIC Provisions;

(g) not knowingly or intentionally take any action or omit to take any action that would cause the termination of the REMIC status of any REMIC created under this Agreement;

(h) pay, from the sources specified in the third paragraph of this Section 8.11, the amount of any federal or state tax, including prohibited transaction taxes as described below, imposed on any REMIC before its termination when and as the same shall be due and payable (but such obligation shall not prevent the Trustee or any other appropriate Person from contesting any such tax in appropriate proceedings and shall not prevent the Trustee from withholding payment of such tax, if permitted by law, pending the outcome of such proceedings);

(i) ensure that federal, state or local income tax or information returns shall be signed by the Trustee or such other person as may be required to sign such returns by the Code or state or local laws, regulations or rules;

(j) maintain records relating to each REMIC created under this Agreement, including the income, expenses, assets, and liabilities thereof and the fair market value and adjusted basis of the assets determined at such intervals as may be required by the Code, as may be necessary to prepare the foregoing returns, schedules, statements or information; and

(k) as and when necessary and appropriate, represent each REMIC created under this Agreement in any administrative or judicial proceedings relating to an examination or audit by any governmental taxing authority, request an administrative adjustment as to any taxable year of such REMIC, enter into settlement agreements with any governmental taxing agency, extend any statute of limitations relating to any tax item of such REMIC, and otherwise act on behalf of such REMIC in relation to any tax matter or controversy involving it.

To enable the Trustee to perform its duties under this Agreement, the Depositor shall provide to the Trustee within ten days after the Closing Date all information or data that the Trustee requests in writing and determines to be relevant for tax purposes to the valuations and offering prices of the Certificates, including the price, yield, prepayment assumption, and projected cash flows of the Certificates and the Mortgage Loans. Thereafter, the Depositor shall provide to the Trustee promptly upon written request therefor any additional information or data that the Trustee may, from time to time, reasonably request to enable the Trustee to perform its duties under this Agreement. The Depositor hereby indemnifies the Trustee for any losses, liabilities, damages, claims, or expenses of the Trustee arising from any errors or miscalculations of the Trustee that result from any failure of the Depositor to provide, or to cause to be provided, accurate information or data to the Trustee on a timely basis.

If any tax is imposed on “prohibited transactions” (as defined in section 860F(a)(2) of the Code) of any REMIC created under this Agreement, on the “net income from foreclosure property” of any REMIC created under this Agreement as defined in section 860G(c) of the Code, on any contribution to any REMIC created under this Agreement after the Startup Day pursuant to section 860G(d) of the Code, or any other tax is imposed, including any minimum tax imposed on any REMIC created hereunder pursuant to sections 23153 and 24874 of the California Revenue and Taxation Code, if not paid as otherwise provided for herein, the tax shall be paid by (i) the Trustee, if any such other tax arises out of or results from negligence of the Trustee in the performance of any of its obligations under this Agreement, (ii) the Servicer or the Seller, in the case of any such minimum tax, if such tax arises out of or results from a breach by the Servicer or Seller of any of their obligations under this Agreement, (iii) the Seller, if any such tax arises out of or results from the Seller’s obligation to repurchase a Mortgage Loan pursuant to Section 2.02 or 2.03, or (iv) in all other cases, or if the Trustee, the Servicer, or the Seller fails to honor its obligations under the preceding clauses (i), (ii), or (iii), any such tax will be paid with amounts otherwise to be distributed to the Certificateholders, as provided in Section 3.09(b).

The Trustee shall file or cause to be filed with the Internal Revenue Service, Form 1041 or such other form as may be applicable, and shall furnish or cause to be furnished to the Holders of the Class L Certificate the Late Payment Fees that are received, in the time or times and in the manner required by the Code.

ARTICLE NINE

TERMINATION

Section 9.01 Termination upon Liquidation or Purchase of the Mortgage Loans.

Subject to Section 9.03, the obligations and responsibilities of the Depositor, the Servicer, and the Trustee created hereby shall terminate upon the earlier of

(a) the purchase by the Servicer of all Mortgage Loans (and REO Properties) at the price equal to the sum of

(i) 100% of the Stated Principal Balance of each Mortgage Loan (other than in respect of a Delinquent Mortgage Loan or REO Property) plus one month’s accrued interest thereon at the applicable Adjusted Mortgage Rate less any amounts collected by the Servicer representing principal and interest due after the related Due Date,

(ii) the lesser of (x) the appraised value of any Delinquent Mortgage Loan or REO Property as determined by the higher of two appraisals completed by two independent appraisers selected by the Servicer at the expense of the Servicer and (y) the Stated Principal Balance of each such Delinquent Mortgage Loan or Mortgage Loan related to such REO Property, in each case plus accrued and unpaid interest thereon at the applicable Adjusted Net Mortgage Rate and

(iii) any costs and damages incurred by the Trust Fund in connection with any violation by each Mortgage Loan of any predatory or abusive lending law and

(b) the later of

(i) the maturity or other liquidation (or any Advance with respect thereto) of the last Mortgage Loan and the disposition of all REO Property and

(ii) the distribution to Certificateholders of all amounts required to be distributed to them pursuant to this Agreement. In no event shall the trusts created hereby continue beyond the expiration of 21 years from the death of the survivor of the descendants of Xxxxxx X. Xxxxxxx, the late Ambassador of the United States to the Court of St. James’s, living on the date of this Agreement.

The right to purchase all Mortgage Loans and REO Properties pursuant to clause (a) above shall be conditioned upon the aggregate Stated Principal Balance of those Mortgage Loans, at the time of any such repurchase, aggregating less than ten percent (10%) of the aggregate Stated Principal Balance of the Mortgage Loans as of the Cut-off Date. The first Distribution Date on which the right to purchase all Mortgage Loans and REO Properties pursuant to clause (a) above first becomes exercisable is referred to as the “Optional Termination Date.” The Servicer shall effect any such repurchase by depositing the purchase price, as calculated above, as of the month preceding the date on which such purchase price shall be distributed to Certificateholders into the Certificate Account. With such repurchase, the Servicer shall acquire any rights or potential rights of the Certificateholders or the Trustee to causes of action against any Person relating to the Mortgage Loans or the origination of the Mortgage Loans, including, without limitation, the right to enforce any breach of a representation or warranty made at any time with respect to the Mortgage Loans.

The Grantor Trust with respect to the Late Payment Fees shall terminate automatically upon termination of the Trust Fund.

Section 9.02 Final Distribution on the Certificates.

If on any Determination Date the Servicer determines that there are no Outstanding Mortgage Loans and no other funds or assets in the Trust Fund other than the funds in the Certificate Account, the Servicer shall direct the Trustee promptly to send a final distribution notice to each Certificateholder. If the Servicer elects to terminate the Trust Fund pursuant to clause (a) of Section 9.01, no later than the 15^th day of the month preceding the month of the final Distribution Date the Servicer shall notify the Depositor and the Trustee of the date the Servicer intends to terminate the Trust Fund and of the applicable repurchase price of the Mortgage Loans and REO Properties.

Notice of any termination of the Trust Fund specifying the Distribution Date on which Certificateholders may surrender their Certificates for payment of the final distribution and cancellation shall be given promptly by the Trustee by letter to Certificateholders mailed not earlier than the 15th day and not later than the last day of the month next preceding the month of such final distribution. Any such notice shall specify (a) the Distribution Date upon which final distribution on the Certificates will be made upon presentation and surrender of Certificates at the office therein designated, (b) the amount of such final distribution, (c) the location of the office or agency at which such presentation and surrender must be made, and (d) that the Record Date otherwise applicable to the Distribution Date is not applicable, distributions being made only upon presentation and surrender of the Certificates at the office therein specified. The Servicer will give such notice to each Rating Agency at the time such notice is given to Certificateholders.

If this notice is given, the Servicer shall cause all funds in the Certificate Account to be remitted to the Trustee for deposit in the Distribution Account on the Business Day before the applicable Distribution Date in an amount equal to the final distribution in respect of the Certificates. Upon such final deposit with respect to the Trust Fund and the receipt by the Trustee of a Request for Release therefor, the Trustee shall promptly release to the Servicer the Mortgage Files for the Mortgage Loans.

Upon presentation and surrender of the Certificates, the Trustee shall cause to be distributed to the Certificateholders of each Class, in each case on the final Distribution Date and in the order set forth in Section 4.02, in proportion to their respective Percentage Interests, with respect to Certificateholders of the same Class, an amount equal to (i) as to each Class of Regular Certificates, its Certificate Balance plus for each such Class accrued interest thereon in the case of an interest-bearing Certificate and (ii) as to the Residual Certificates, any amount remaining on deposit in the Distribution Account (other than the amounts retained to meet claims) after application pursuant to clause (i) above. Notwithstanding the reduction of the Certificate Balance of any Class of Certificates to zero, such Class will be outstanding hereunder solely for the purpose of receiving distributions and for no other purpose until the termination of the respective obligations and responsibilities of the Depositor, the Servicer and the Trustee hereunder in accordance with Article Nine. The foregoing provisions are intended to distribute to each Class of Regular Certificates any accrued and unpaid interest and principal to which they are entitled based on the Pass-Through Rates and actual Class Certificate Balances set forth in the Preliminary Statement upon liquidation of the Trust Fund.

If any affected Certificateholder does not surrender its Certificates for cancellation within six months after the date specified in the above mentioned written notice, the Trustee shall give a second written notice to the remaining Certificateholders to surrender their Certificates for cancellation and receive the final distribution with respect thereto. If within six months after the second notice all the applicable Certificates shall not have been surrendered for cancellation, the Trustee may take appropriate steps, or may appoint an agent to take appropriate steps, to contact the remaining Certificateholders concerning surrender of their Certificates, and the cost thereof shall be paid out of the funds and other assets which remain a part of the Trust Fund. If within one year after the second notice all Certificates shall not have been surrendered for cancellation, then the Class A-R Certificateholders shall be entitled to all unclaimed funds and other assets of the Trust Fund which remain subject hereto.

Section 9.03 Additional Termination Requirements.

(a) If the Servicer exercises its purchase option with respect to the Mortgage Loans as provided in Section 9.01, the Trust Fund shall be terminated in accordance with the following additional requirements, unless the Trustee has been supplied with an Opinion of Counsel, at the expense of the Servicer, to the effect that the failure to comply with the requirements of this Section 9.03 will not (i) result in the imposition of taxes on “prohibited transactions” on any REMIC created hereunder as defined in section 860F of the Code, 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) The Trustee shall sell all of the assets of the Trust Fund to the Servicer, and, within 90 days of such sale, shall distribute to the Certificateholders the proceeds of such sale in complete liquidation of each REMIC created under this Agreement.

(c) The Trustee shall attach a statement to the final federal income tax return for each REMIC created under this Agreement stating that pursuant to Treasury Regulation § 1.860F-1, the first day of the 90-day liquidation period for such REMIC was the date on which the Trustee sold the assets of the Trust Fund to the Servicer.

ARTICLE TEN

MISCELLANEOUS PROVISIONS

Section 10.01 Amendment.

This Agreement may be amended from time to time by the Depositor, the Servicer and the Trustee without the consent of any of the Certificateholders (i) to cure any ambiguity or mistake, (ii) to correct any defective provision in this Agreement or to supplement any provision in this Agreement which may be inconsistent with any other provision in this Agreement, (iii) to conform this Agreement to the Prospectus Supplement, (iv) to add to the duties of the Depositor, the Seller or the Servicer, (v) to modify, alter, amend, add to or rescind any of the terms or provisions contained in this Agreement to comply with any rules or regulations promulgated by the Commission from time to time, (vi) to add any other provisions with respect to matters or questions arising under this Agreement, or (vii) to modify, alter, amend, add to, or rescind any of the terms or provisions contained in this Agreement.

No action pursuant to clauses (v), (vi) or (vii) above may, as evidenced by an Opinion of Counsel (which Opinion of Counsel shall not be an expense of the Trustee or the Trust Fund), adversely affect in any material respect the interests of any Certificateholder. The amendment shall not be deemed to adversely affect in any material respect the interests of the Certificateholders if the Person requesting the amendment obtains a letter from each Rating Agency stating that the amendment would not result in the downgrading, qualification or withdrawal of the respective ratings then assigned to the Certificates. Any such letter in and of itself will not represent a determination as to the materiality of any amendment and will represent a determination only as to the credit issues affecting any rating. Each party to this Agreement agrees that it will cooperate with each other party in amending this Agreement pursuant to clause (v) above.

The Trustee, the Depositor, and the Servicer also may at any time and from time to time amend this Agreement without the consent of the Certificateholders to modify, eliminate or add to any of its provisions to the extent necessary or helpful to (i) maintain the qualification of any REMIC created under this Agreement as a REMIC under the Code, (ii) avoid or minimize the risk of the imposition of any tax on any REMIC created under this Agreement pursuant to the Code that would be a claim at any time before the final redemption of the Certificates, or (iii) comply with any other requirements of the Code, if the Trustee has been provided an Opinion of Counsel, which opinion shall be an expense of the party requesting such opinion but in any case shall not be an expense of the Trustee or the Trust Fund, to the effect that the action is necessary or helpful for one of the foregoing purposes.

This Agreement may also be amended from time to time by the Depositor, the Servicer, and the Trustee with the consent of the Holders of Certificates evidencing Percentage Interests aggregating not less than 51% of each Class of Certificates adversely affected thereby for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Agreement or of modifying in any manner the rights of the Holders of Certificates. As long as any Voting Rights are held by parties other than the Seller, its Affiliates, or its agents, as the Seller shall certify to the Trustee upon any such entity obtaining such ownership, Voting Rights of Certificates held by the Seller, its Affiliates or its agents will be excluded from participating in such voting arrangements, and excluded from determining the 51% threshold. No amendment shall

(i) reduce in any manner the amount of, or delay the timing of, payments required to be distributed on any Certificate without the consent of the Holder of such Certificate,

(ii) amend, modify, add to, rescind, or alter in any respect Section 10.13, notwithstanding any contrary provision of this Agreement, without the consent of the Holders of Certificates evidencing Percentage Interests aggregating not less than 66 2/3% (provided, however, that no Certificates held by the Seller, the Depositor or any Affiliate thereby shall be given effect for the purpose of calculating any such aggregation of Percentage Interests), or

(iii) reduce the aforesaid percentages of Certificates the Holders of which are required to consent to any such amendment, without the consent of the Holders of all such Certificates then outstanding.

Notwithstanding any contrary provision of this Agreement, the Trustee shall not consent to any amendment to this Agreement unless (i) it shall have first received an Opinion of Counsel, which opinion shall not be an expense of the Trustee or the Trust Fund, to the effect that such amendment will not cause the imposition of any tax on any REMIC created under this Agreement or the Certificateholders or cause any REMIC created hereunder to fail to qualify as a REMIC at any time that any Certificates are outstanding and (ii) because the Trust Fund is required to be a Qualifying Special Purpose Entity (as that term is defined in Statement of Financial Accounting Standards No. 140 (“SFAS 140”), in order for the Seller to continue to account for the transfer of the Mortgage Loans under this Agreement as a sale under SFAS 140, prior to the parties hereto entering into such an amendment, the Trustee shall receive an Officer’s Certificate, which shall not be an expense of the Trustee or the Trust Fund, to the effect that such amendment would not “significantly change” (within the meaning of SFAS 140) the permitted activities of the Trust Fund so as to cause the Trust Fund to fail to qualify as a Qualifying Special Purpose Entity.

Promptly after the execution of any amendment to this Agreement requiring the consent of Certificateholders, the Trustee shall furnish written notification of the substance or a copy of such amendment to each Certificateholder and each Rating Agency.

It shall not be necessary for the consent of Certificateholders under this Section 10.01 to approve the particular form of any proposed amendment, but it shall be sufficient if such consent shall approve the substance thereof. The manner of obtaining such consents and of evidencing the authorization of the execution thereof by Certificateholders shall be subject to such reasonable regulations as the Trustee may prescribe.

Nothing in this Agreement shall require the Trustee to enter into an amendment without receiving an Opinion of Counsel (which Opinion shall not be an expense of the Trustee or the Trust Fund), satisfactory to the Trustee that (i) such amendment is permitted and is not prohibited by this Agreement and that all requirements for amending this Agreement have been complied with; and (ii) either (A) the amendment does not adversely affect in any material respect the interests of any Certificateholder or (B) the conclusion set forth in the preceding clause (A) is not required to be reached pursuant to this Section 10.01.

Section 10.02 Recordation of Agreement; Counterparts.

This Agreement is subject to recordation in all appropriate public offices for real property records in all the counties or other comparable jurisdictions in which any or all of the properties subject to the Mortgages are situated, and in any other appropriate public recording office or elsewhere, such recordation to be effected by the Servicer at its expense, but only upon receipt of an Opinion of Counsel to the effect that such recordation materially and beneficially affects the interests of the Certificateholders.

100

For the purpose of facilitating the recordation of this Agreement as herein provided and for other purposes, this Agreement may be executed simultaneously in any number of counterparts, each of which counterparts shall be deemed to be an original, and such counterparts shall constitute but one and the same instrument.

Section 10.03 Governing Law.

THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE SUBSTANTIVE LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED IN THE STATE OF NEW YORK AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HERETO AND THE CERTIFICATEHOLDERS SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

Section 10.04 Intention of Parties.

It is the express intent of the parties hereto that the conveyance (i) of the Mortgage Loans by the Seller to the Depositor and (ii) of the Trust Fund by the Depositor to the Trustee each be, and be construed as, an absolute sale thereof. It is, further, not the intention of the parties that such conveyances be deemed a pledge thereof. However, if, notwithstanding the intent of the parties, the assets are held to be the property of the Seller or Depositor, as the case may be, or if for any other reason this Agreement is held or deemed to create a security interest in either such assets, then (i) this Agreement shall be deemed to be a security agreement within the meaning of the UCC and (ii) the conveyances provided for in this Agreement shall be deemed to be an assignment and a grant (i) by the Seller to the Depositor or (ii) by the Depositor to the Trustee, for the benefit of the Certificateholders, of a security interest in all of the assets transferred, whether now owned or hereafter acquired.

The Seller and the Depositor for the benefit of the Certificateholders shall, to the extent consistent with this Agreement, take such actions as may be necessary to ensure that, if this Agreement were deemed to create a security interest in the Trust Fund, such security interest would be deemed to be a perfected security interest of first priority under applicable law and will be maintained as such throughout the term of the Agreement. The Depositor shall arrange for filing any Uniform Commercial Code continuation statements in connection with any security interest granted or assigned to the Trustee for the benefit of the Certificateholders.

For the protection and enforcement of this Section 10.08, each Certificateholder and the Trustee shall be entitled to any relief that can be given either at law or in equity.

Neither the Servicer nor the Depositor will request delivery of a certification under this clause unless the Trustee is required under the Exchange Act to file an annual report on Form 10-K with respect to the Trust Fund. In the event that prior to the filing date of the Form 10-K in March of each year, the Servicer or the Depositor has actual knowledge of information material to the Xxxxxxxx-Xxxxx Certification, the Servicer or the Depositor, as the case may be, shall promptly notify the Servicer and the Trustee.

(4) Immediately before the assignment of the Mortgage Loans to the Depositor, the Seller had good title to, and was the sole owner of, each Mortgage Loan free and clear of any pledge, lien, encumbrance or security interest and had full right and authority, subject to no interest or participation of, or agreement with, any other party, to sell and assign the same pursuant to the Pooling and Servicing Agreement.

(5) As of the Closing Date, there was no delinquent tax or assessment lien against the related Mortgaged Property.

(6) There is no valid offset, defense or counterclaim to any Mortgage Note or Mortgage, including the obligation of the Mortgagor to pay the unpaid principal of or interest on such Mortgage Note.

S-IV-1

(8) No Mortgaged Property has been materially damaged by water, fire, earthquake, windstorm, flood, tornado or similar casualty (excluding casualty from the presence of hazardous wastes or hazardous substances, as to which the Seller makes no representation) so as to affect adversely the value of the related Mortgaged Property as security for the Mortgage Loan.

(9) Each Mortgage Loan at origination complied in all material respects with applicable local, state and federal laws and regulations, including usury, equal credit opportunity, real estate settlement procedures, truth-in-lending, and disclosure laws, or any noncompliance does not have a material adverse effect on the value of the related Mortgage Loan.

(10) The Seller has not modified the Mortgage in any material respect (except that a Mortgage Loan may have been modified by a written instrument which has been recorded or submitted for recordation, if necessary, to protect the interests of the Certificateholders and which has been delivered to the Trustee); satisfied, cancelled or subordinated such Mortgage in whole or in part; released the related Mortgaged Property in whole or in part from the lien of such Mortgage; or executed any instrument of release, cancellation, modification or satisfaction with respect thereto.

(11) A lender’s policy of title insurance together with a condominium endorsement and extended coverage endorsement, if applicable, in an amount at least equal to the Cut-off Date Principal Balance of each such Mortgage Loan or a commitment (binder) to issue the same was effective on the date of the origination of each Mortgage Loan and each such policy is valid and remains in full force and effect.

(12) Each Mortgage Loan was originated (within the meaning of Section 3(a)(41) of the Securities Exchange Act of 1934, as amended) by an entity that satisfied at the time of origination the requirements of Section 3(a)(41) of the Securities Exchange Act of 1934, as amended.

(13) All of the improvements which were included for the purpose of determining the Appraised Value of the Mortgaged Property lie wholly within the boundaries and building restriction lines of such property, and no improvements on adjoining properties encroach upon the Mortgaged Property, unless such failure to be wholly within such boundaries and restriction lines or such encroachment, as the case may be, does not have a material effect on the value of the Mortgaged Property.

(14) As of the date of origination of each Mortgage Loan, no improvement located on or being part of the Mortgaged Property is in violation of any applicable zoning law or regulation unless such violation would not have a material adverse effect on the value of the related Mortgaged Property. All inspections, licenses and certificates required to be made or issued with respect to all occupied portions of the Mortgaged Property and, with respect to the use and occupancy of the same, including certificates of occupancy and fire underwriting certificates, have been made or obtained from the appropriate authorities, unless the lack thereof would not have a material adverse effect on the value of the Mortgaged Property.

A-2

(16) The proceeds of the Mortgage Loan have been fully disbursed and there is no requirement for future advances thereunder.

(17) The related Mortgage contains customary and enforceable provisions which render the rights and remedies of the holder thereof adequate for the realization against the Mortgaged Property of the benefits of the security, including, (i) in the case of a Mortgage designated as a deed of trust, by trustee’s sale, and (ii) otherwise by judicial foreclosure.

Anything to the contrary in this item (19) notwithstanding, no breach of this item (19) shall be deemed to give rise to any obligation of the Seller to repurchase or substitute for such affected Mortgage Loan or Loans so long as the Servicer maintains a blanket policy pursuant to the second paragraph of Section 3.10(a) of the Pooling and Servicing Agreement.

(20) If at the time of origination of each Mortgage Loan, the related Mortgaged Property was in an area then identified in the Federal Register by the Federal Emergency Management Agency as having special flood hazards, a flood insurance policy in a form meeting the then-current requirements of the Flood Insurance Administration is in effect with respect to the Mortgaged Property with a generally acceptable carrier.

(33) The Pooling and Servicing Agreement creates a valid and continuing “security interest” (as defined in Section 1-201(37) of the UCC) in each Mortgage Note in favor of the Trustee, which security interest is prior to all other liens and is enforceable as such against creditors of and purchasers from the Depositor. Each Mortgage Note constitutes “promissory notes” (as defined in Section 9-102(a)(65) of the UCC).

Mortgage Pass-Through Certificates, Series 200_-_

This Certificate is one of a duly authorized issue of Certificates designated as IndyMac MBS, Inc. Mortgage Pass-Through Certificates, of the Series specified on the face hereof (herein collectively called the “Certificates”), and representing a beneficial ownership interest in the Trust Fund created by the Agreement.

The Certificateholder, by its acceptance of this Certificate, agrees that it will look solely to the funds on deposit in the Distribution Account for payment hereunder and that the Trustee is not liable to the Certificateholders for any amount payable under this Certificate or the Agreement or, except as expressly provided in the Agreement, subject to any liability under the Agreement.

This Certificate does not purport to summarize the Agreement and reference is made to the Agreement for the interests, rights and limitations of rights, benefits, obligations and duties evidenced thereby, and the rights, duties and immunities of the Trustee.

Pursuant to the terms of the Agreement, a distribution will be made on the 25th day of each month or, if such 25th day is not a Business Day, the Business Day immediately following (the “Distribution Date”), commencing on the first Distribution Date specified on the face hereof, to the Person in whose name this Certificate is registered at the close of business on the applicable Record Date in an amount equal to the product of the Percentage Interest evidenced by this Certificate and the amount required to be distributed to Holders of Certificates of the Class to which this Certificate belongs on such Distribution Date pursuant to the Agreement. The Record Date applicable to each Distribution Date is the last Business Day of the month next preceding the month of such Distribution Date.

Distributions on this Certificate shall be made by wire transfer of immediately available funds to the account of the Holder hereof at a bank or other entity having appropriate facilities therefor, if such Certificateholder shall have so notified the Trustee in writing at least five Business Days prior to the Record Date and such Certificateholder shall satisfy the conditions to receive such form of payment set forth in the Agreement, or, if not, by check mailed by first class mail to the address of such Certificateholder appearing in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the Corporate Trust Office or such other location specified in the notice to Certificateholders of such final distribution.

The Agreement permits, with certain exceptions therein provided, the amendment thereof and the modification of the rights and obligations of the Trustee and the rights of the Certificateholders under the Agreement at any time by the Depositor, the Servicer and the Trustee with the consent of the Holders of Certificates affected by such amendment evidencing the requisite Percentage Interest, as provided in the Agreement. Any such consent by the Holder of this Certificate shall be conclusive and binding on such Holder and upon all future Holders of this Certificate and of any Certificate issued upon the transfer hereof or in exchange therefor or in lieu hereof whether or not notation of such consent is made upon this Certificate. The Agreement also permits the amendment thereof, in certain limited circumstances, without the consent of the Holders of any of the Certificates.

E-1

As provided in the Agreement and subject to certain limitations therein set forth, the transfer of this Certificate is registrable in the Certificate Register of the Trustee upon surrender of this Certificate for registration of transfer at the Corporate Trust Office, accompanied by a written instrument of transfer in form satisfactory to the Trustee and the Certificate Registrar duly executed by the holder hereof or such holder’s attorney duly authorized in writing, and thereupon one or more new Certificates of the same Class in authorized denominations and evidencing the same aggregate Percentage Interest in the Trust Fund will be issued to the designated transferee or transferees.

The Certificates are issuable only as registered Certificates without coupons in denominations specified in the Agreement. As provided in the Agreement and subject to certain limitations therein set forth, Certificates are exchangeable for new Certificates of the same Class in authorized denominations and evidencing the same aggregate Percentage Interest, as requested by the Holder surrendering the same.

No service charge will be made for any such registration of transfer or exchange, but the Trustee may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

The Depositor, the Servicer, the Seller and the Trustee and any agent of the Depositor or the Trustee may treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and neither the Depositor, the Trustee, nor any such agent shall be affected by any notice to the contrary.

On any Distribution Date on which the aggregate Stated Principal Balance of the Mortgage Loans in the mortgage pool is less than 10% of the Cut-off Date Pool Principal Balance, the Servicer will have the option to repurchase, in whole, from the Trust Fund all remaining Mortgage Loans in the mortgage pool and all property acquired in respect of the Mortgage Loans in the mortgage pool at a purchase price determined as provided in the Agreement. In the event that no such optional termination occurs, the obligations and responsibilities created by the Agreement will terminate upon the later of the maturity or other liquidation (or any advance with respect thereto) of the last Mortgage Loan remaining in the Trust Fund or the disposition of all property in respect thereof and the distribution to Certificateholders of all amounts required to be distributed pursuant to the Agreement. In no event, however, will the trust created by the Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants living at the date of the Agreement of a certain person named in the Agreement.

Any term used herein that is defined in the Agreement shall have the meaning assigned in the Agreement, and nothing herein shall be deemed inconsistent with that meaning.

COUNTY OF _____________	)

The undersigned, being first duly sworn, deposes and says as follows:

1. The undersigned is an officer of , the proposed Transferee of an Ownership Interest in a Class A-R Certificate (the “Certificate”) issued pursuant to the Pooling and Servicing Agreement, (the “Agreement”), relating to the above-referenced Series, by and among IndyMac MBS, Inc., as depositor (the “Depositor”), IndyMac Bank, F.S.B., as seller and servicer and Deutsche Bank National Trust Company, as Trustee. Capitalized terms used, but not defined herein or in Exhibit 1 hereto, shall have the meanings ascribed to such terms in the Agreement. The Transferee has authorized the undersigned to make this affidavit on behalf of the Transferee.

2. The Transferee is, as of the date hereof, and will be, as of the date of the Transfer, a Permitted Transferee. The Transferee is acquiring its Ownership Interest in the Certificate for its own account.

3. The Transferee has been advised of, and understands that (i) a tax will be imposed on Transfers of the Certificate to Persons that are not Permitted Transferees; (ii) such tax will be imposed on the transferor, or, if such Transfer is through an agent (which includes a broker, nominee or middleman) for a Person that is not a Permitted Transferee, on the agent; and (iii) the Person otherwise liable for the tax shall be relieved of liability for the tax if the subsequent Transferee furnished to such Person an affidavit that such subsequent Transferee is a Permitted Transferee and, at the time of Transfer, such Person does not have actual knowledge that the affidavit is false.

4. The Transferee has been advised of, and understands that a tax will be imposed on a “pass-through entity” holding the Certificate if at any time during the taxable year of the pass-through entity a Person that is not a Permitted Transferee is the record holder of an interest in such entity. The Transferee understands that such tax will not be imposed for any period with respect to which the record holder furnishes to the pass-through entity an affidavit that such record holder is a Permitted Transferee and the pass-through entity does not have actual knowledge that such affidavit is false. (For this purpose, a “pass-through entity” includes a regulated investment company, a real estate investment trust or common trust fund, a partnership, trust or estate, and certain cooperatives and, except as may be provided in Treasury Regulations, persons holding interests in pass-through entities as a nominee for another Person.)

5. The Transferee has reviewed the provisions of Section 5.02(c) of the Agreement (attached hereto as Exhibit 2 and incorporated herein by reference) and understands the legal consequences of the acquisition of an Ownership Interest in the Certificate including, without limitation, the restrictions on subsequent Transfers and the provisions regarding voiding the Transfer and mandatory sales. The Transferee expressly agrees to be bound by and to abide by the provisions of Section 5.02(c) of the Agreement and the restrictions noted on the face of the Certificate. The Transferee understands and agrees that any breach of any of the representations included herein shall render the Transfer to the Transferee contemplated hereby null and void.

In connection with any such Transfer by the Transferee, the Transferee agrees to deliver to the Trustee a certificate substantially in the form set forth as Exhibit J to the Agreement (a “Transferor Certificate”) to the effect that such Transferee has no actual knowledge that the Person to which the Transfer is to be made is not a Permitted Transferee.

11. The Transferee is not a foreign permanent establishment or fixed base (within the meaning of an applicable income tax treaty) of a U.S. taxpayer.

12. The Transferee will not transfer the Certificates, directly or indirectly, to a foreign permanent establishment or fixed base (within the meaning of an applicable income tax treaty) of the Transferee or another U.S. taxpayer.

For purposes of the preceding sentence, the gross assets and net assets of a Transferee do not include any obligation of any Related Person, as defined below, or any other asset if a principal purpose for holding or acquiring the other asset is to permit the Transferee to satisfy the conditions of this paragraph 15(a); (ii) The Transferee is an Eligible Corporation, as defined below, and hereby agrees that any subsequent transfer of the interest will be to another Eligible Corporation in a transaction that satisfies this Transfer Affidavit, including this paragraph 15(a); and (iii) The Transferee has not given the Transferor any reason to know that the Transferee will not honor the restrictions on subsequent transfers of the residual interest or that the Transferee cannot or will not pay any taxes associated with the residual interest; or

The Term “Related Person” means any person that bears a relationship to the Transferee enumerated in section 267(b) or 707(b)(1) of the Code, using "20 percent" instead of "50 percent" where it appears under the provisions; or is under common control (within the meaning of section 52(a) and (b) of the Code) with the Transferee.

15. Either (i) the Transferee is not an employee benefit plan that is subject to ERISA or a plan that is subject to Section 4975 of the Code, and the Transferee is not acting on behalf of or with plan assets of such a plan; or (ii) the Transferee is an insurance company that is investing funds contained in an “insurance company general account” (as such term is defined in Section V(e) of Prohibited Transaction Class Exemption 95-60 (“PTCE 95-60”) and the purchase and holding of the Class A-R Certificate satisfy the requirements for exemptive relief under Sections I and III of PTCE 95-60.

Section 5.02(c) of the Agreement

(ii) No Ownership Interest in a Residual Certificate may be registered on the Closing Date or thereafter transferred, and the Trustee shall not register the Transfer of any Residual Certificate unless, in addition to the certificates required to be delivered to the Trustee under subparagraph (b) above, the Trustee shall have been furnished with an affidavit (a “Transfer Affidavit”) of the initial owner or the proposed transferee in the form attached hereto as Exhibit I.

(iv) Any attempted or purported Transfer of any Ownership Interest in a Residual Certificate in violation of the provisions of this Section 5.02(c) shall be absolutely null and void and shall vest no rights in the purported Transferee. If any purported transferee shall become a Holder of a Residual Certificate in violation of the provisions of this Section 5.02(c), then the last preceding Permitted Transferee shall be restored to all rights as Holder thereof retroactive to the date of registration of Transfer of such Residual Certificate. The Trustee shall be under no liability to any Person for any registration of Transfer of a Residual Certificate that is in fact not permitted by Section 5.02(b) and this Section 5.02(c) or for making any payments due on such Certificate to the Holder thereof or taking any other action with respect to such Holder under the provisions of this Agreement so long as the Transfer was registered after receipt of the Transfer Affidavit, Transferor Certificate and either the Rule 144A Letter or the Investment Letter. The Trustee shall be entitled but not obligated to recover from any Holder of a Residual Certificate that was in fact not a Permitted Transferee at the time it became a Holder or, at such subsequent time as it became other than a Permitted Transferee, all payments made on such Residual Certificate at and after either such time. Any such payments so recovered by the Trustee shall be paid and delivered by the Trustee to the last preceding Permitted Transferee of such Certificate.
