(b) No Accrued Note Interest will be payable with respect to any Class of Notes after the Payment Date on which the Note Principal Balance or Notional Amount of such Note has been reduced to zero.

(c) Each distribution with respect to a Book-Entry Note shall be paid to the Depository, as Holder thereof, and the Depository shall be responsible for crediting the amount of such distribution to the accounts of its Depository Participants in accordance with its normal procedures. Each Depository Participant shall be responsible for disbursing such distribution to the Note Owners that it represents and to each indirect participating brokerage firm (a “brokerage firm” or “indirect participating firm”) for which it acts as agent. Each brokerage firm shall be responsible for disbursing funds to the Note Owners that it represents. None of the Securities Administrator, the Depositor or the Master Servicer shall have any responsibility therefor.

(d) On each Payment Date, the Securities Administrator shall deposit in the Certificate Payment Account all amounts it received pursuant to this Section 3.03 for the purpose of distributing such funds to the Certificateholders. The Securities Administrator shall make distributions to the Certificateholders under the Trust Agreement as directed by the Securities Administrator hereunder.

(e) Any installment of interest or principal, if any, payable on any Note that is punctually paid or duly provided for by the Issuing Entity on the applicable Payment Date shall, if such Holder shall have so requested at least five Business Days prior to the related Record Date, be paid to each Holder of record on the preceding Record Date, by wire transfer to an account specified in writing by such Holder as of the preceding Record Date or in all other cases or if no such instructions have been delivered to the Securities Administrator, by check to such Noteholder mailed to such Holder’s address as it appears in the Note Register in the amount required to be distributed to such Holder on such Payment Date pursuant to such Holder’s Notes; provided, however, that the Securities Administrator shall not pay to such Holders any amount required to be withheld from a payment to such Holder by the Code.

(f) Net Interest Shortfalls on the Mortgage Loans in a Loan Group will be allocated among the holders of each Class of Subordinate Notes and Class X Notes, on a pro rata basis, in proportion to the respective amounts of Accrued Note Interest for that Payment Date that would have been allocated thereto in the absence of such Net Interest Shortfalls for such Payment Date. In addition, the amount of any Net Interest Shortfalls with respect to the Mortgage Loans in a Loan Group will constitute unpaid Accrued Note Interest and will be distributable to holders of the related Classes of Notes entitled to such amounts on subsequent Payment Dates, to the extent of the Available Funds for such Loan Group remaining after current interest payments. Any such

amounts so carried forward will not bear interest. Any Net Interest Shortfalls will not be offset by a reduction in the servicing compensation of the Servicers or the Master Servicer or otherwise, except to the limited extent with respect to certain Prepayment Interest Shortfalls.

(g) The Note Principal Balance of each Note shall be due and payable in full on the Final Scheduled Payment Date for such Note as provided in the forms of Note set forth in Exhibits A-1, A-2 and A-3 to this Indenture. All principal payments on the Notes shall be made to the Noteholders entitled thereto in accordance with the Percentage Interests represented by such Notes. Upon notice to the Securities Administrator by the Issuing Entity, the Securities Administrator shall notify the Person in whose name a Note is registered at the close of business on the Record Date preceding the Final Scheduled Payment Date or other final Payment Date (including any final Payment Date resulting from any redemption pursuant to Section 8.06 hereof). Such notice shall to the extent practicable be mailed no later than five Business Days prior to such Final Scheduled Payment Date or other final Payment Date and shall specify that payment of the principal amount and any interest due with respect to such Note at the Final Scheduled Payment Date or other final Payment Date will be payable only upon presentation and surrender of such Note and shall specify the place where such Note may be presented and surrendered for such final payment. No interest shall accrue on the Notes on or after the Final Scheduled Payment Date or any such other final Payment Date.

(h) On any Payment Date on which there is an Undercollateralized Group, the priority and manner of distributions for the Notes described above shall be supplemented as follows:

(A) amounts then on deposit in the Reserve Fund shall be distributed as principal to the Senior Notes of any Undercollateralized Group on such Payment Date, on a pro rata basis, to the extent of the Undercollateralized Amount for such Undercollateralized Group on such Payment Date (provided that, if there are multiple Undercollateralized Groups on such Payment Date, amounts then on deposit in the Reserve Fund shall first be allocated to each such Undercollateralized Group in proportion to the Undercollateralized Amount for each such Undercollateralization Group on such Payment Date);

(B) any amounts from Available Funds otherwise distributable as principal on the Subordinate Notes, as described in Section 3.03(V)(B) of this Indenture, in reverse order of priority set forth in Section 3.03(V)(B), shall be distributed (i) first, as principal to the Senior Notes of any Undercollateralized Group, on a pro rata basis, to the extent of the remaining Undercollateralized Amount for such Undercollateralized Group on such Payment Date after the distribution in clause (A) above (provided that, if there are multiple Undercollateralized Groups on such Payment Date, such amounts from Available Funds shall first be allocated to each such Undercollateralized Group in proportion to the remaining Undercollateralized Amount for each such Undercollateralization Group on such Payment Date after the distribution in clause (A) above) and (ii) second, to the Subordinate Notes in the same manner and priority set forth in Section 3.03(V)(B); and

(C) in the event that the Note Principal Balances of the Subordinate Notes have been reduced to zero prior to such Payment Date, any amounts from Available Funds related to any Overcollateralized Group for such Payment Date shall be distributed as principal to the Offered Notes of any Undercollateralized Group, on a pro rata basis, to the extent of the remaining Undercollateralized Amount for such Undercollateralized Group on such Payment Date after the distribution in clause (A) above (provided that, if there are multiple Undercollateralized Groups on such Payment Date, such amounts from Available Funds shall first be allocated to each such Undercollateralized Group in proportion to the remaining Undercollateralized Amount for each such Undercollateralization Group on such Payment Date after the distribution in clause (A) above).

If, on any Payment Date, (i) the aggregate Note Principal Balance of the Senior Notes related to a Loan Group has been reduced to zero, (ii) the Note Principal Balances of the Subordinate Notes have not been reduced to zero, and (iii) either (a) the weighted average of the Subordinate Percentages of the Subordinate Certificates on such Payment Date is less than two times the initial weighted average of the Subordinate Percentages of the Subordinate Notes, or (b) the aggregate Scheduled Principal Balance of the Mortgage Loans Delinquent 60 days or more (including for this purpose any such Mortgage Loans in foreclosure and bankruptcy and Mortgage Loans with respect to which the related Mortgaged Property has been acquired by the Issuing Entity), averaged over the last six months, as a percentage of the aggregate Note Principal Balance of the Subordinate Notes equals or exceeds 50%, then any amounts from Available Funds related to such retired Senior Notes otherwise distributable in respect of principal under clauses (ii), (iii), (iv) and (v) of the definition of Subordinate Optimal Principal Amount on each Class of Subordinate Notes, in reverse order of payment priority set forth in Section 3.03(V)(B), shall be deposited into the Reserve Fund for application on future Payment Dates to make principal payments on any outstanding Senior Notes related to an Undercollateralized Group as described in this Section 3.03(h). If any amounts remain in the Reserve Fund after the Note Principal Balances of all of the Senior Notes have been reduced to zero, such amounts shall be allocated to the Subordinate Notes in the same manner and priorities as set forth in Section 3.03(V)(B) of this Indenture; provided, however, if after making such payments, the aggregate Note Principal Balance of the Subordinate Notes exceeds the aggregate Scheduled Principal Balance of the Mortgage Loans as of the related Due Date, the Note Principal Balances of the Subordinate Notes will be reduced, on a pro rata basis, by the amount of such excess in reverse order of payment priority set forth in Section 3.03(V)(B).

Section 3.04 Reserve Fund. On or before the Closing Date, the Securities Administrator shall establish a Reserve Fund on behalf of the Holders of the Notes. The Reserve Fund shall be entitled “Reserve Fund, Wells Fargo Bank, N.A. as Securities Administrator for the benefit of holders of Bear Stearns Arm Trust 2007-2, Mortgage-Backed Notes, Series 2007-2”. The Securities Administrator shall deposit in the Reserve Fund the Available Funds described in Section 3.03(h) that are related to a group of retired Senior Notes and may otherwise be distributable in respect of principal on the Subordinate Notes pursuant to such Section 3.03(h) on each relevant Payment Date. On each Payment Date, the Securities Administrator shall remit amounts then on deposit in the Reserve Fund to the Holders of the Senior Notes of any Undercollateralized Group in the manner and priorities set forth in clause (A) of Section 3.03(h) hereof, or if no Senior Notes remain outstanding, to the Holders of the Subordinate Notes in the manner and priorities set forth at the end of such Section 3.03(h).

(a) With respect to that portion of the Collateral described in clauses (a) through (c) of the definition of Trust Estate, the Issuing Entity represents to the Indenture Trustee that:

(i) This Indenture creates a valid and continuing security interest (as defined in the applicable UCC) in the Collateral in favor of the Indenture Trustee, which security interest is prior to all other liens, and is enforceable as such as against creditors of and purchasers from the Issuing Entity.

(ii) The Collateral constitutes “deposit accounts,” “instruments” or “certificated securities,” as applicable within the meaning of the applicable UCC.

(iii) The Issuing Entity owns and has good and marketable title to the Collateral, free and clear of any lien, claim or encumbrance of any Person.

(iv) The Issuing Entity has caused or will have caused, within ten days of the Closing Date, the filing of all appropriate financing statements in the proper filing office in the appropriate jurisdictions under applicable law in order to perfect the security interest in the Collateral granted to the Indenture Trustee hereunder.

(v) Other than the security interest granted to the Indenture Trustee pursuant to this Indenture, or the conveyances that the Issuing Entity would be required to make following a TMP Trigger Event, the Issuing Entity has not pledged, assigned, sold, granted a security interest in, or otherwise conveyed any of the Collateral. The Issuing Entity has not authorized the filing of and

is not aware of any financing statements against the Issuing Entity that include a description of collateral covering the Collateral other than any financing statement relating to the security interest granted to the Indenture Trustee hereunder or that has been terminated.

(vi) The Collateral is not in the name of any Person other than the Issuing Entity or the Indenture Trustee. The Issuing Entity has in its possession all original copies of the security certificates that constitute or evidence the Collateral.

(vii) The foregoing representations may not be waived and shall survive the issuance of the Notes.

Section 3.24 Allocation of Realized Losses. (a) On or prior to each Payment Date, the Master Servicer shall determine, based solely on information provided to it by the Servicer the amount of any Realized Loss in respect of each Mortgage Loan that occurred during the immediately preceding calendar month.

(b) With respect to any Notes (other than the Class X Notes) on any Payment Date, the principal portion of each Realized Loss on a Mortgage Loan shall be allocated as follows:

first, to the Class B-6 Notes until the Note Principal Balance thereof has been reduced to zero;

second, to the Class B-5 Notes until the Note Principal Balance thereof has been reduced to zero;

third, to the Class B-4 Notes until the Note Principal Balance thereof has been reduced to zero;

fourth, to the Class B-3 Notes until the Note Principal Balance thereof has been reduced to zero;

fifth, to the Class B-2 Notes until the Note Principal Balance thereof has been reduced to zero;

sixth, to the Class B-1 Notes until the Note Principal Balance thereof has been reduced to zero;

seventh, to the extent that such Realized Losses related to the Group I Mortgage Loans exceed amounts on deposit in the Reserve Fund, to the Class I-A-2 Notes, and then, to the Class I-A-1 Notes, in each case until its Note Principal Balance has been reduced to zero; to the extent that such Realized Losses related to the Group II Mortgage Loans exceed amounts on deposit in

the Reserve Fund, to the Class II-A-2 Notes, and then, to the Class II-A-1 Notes, in each case until its Note Principal Balance has been reduced to zero; to the extent that such Realized Losses related to the Group III Mortgage Loans exceed amounts on deposit in the Reserve Fund, to the Class III-A-2 Notes, and then, to the Class III-A-1 Notes, in each case until its Note Principal Balance has been reduced to zero; and to the extent that such Realized Losses related to the Group IV Mortgage Loans exceed amounts on deposit in the Reserve Fund, to the Class IV-A-2 Notes, and then, to the Class IV-A-1 Notes, in each case until its Note Principal Balance has been reduced to zero.

(c) Notwithstanding the foregoing clause (b), no such allocation of any Realized Loss shall be made on a Payment Date to any Class or Classes of Senior Notes to the extent that such allocation would result in the reduction of the aggregate Note Principal Balance of all of the related Classes of Notes as of such Payment Date, after giving effect to all distributions and prior allocations of Realized Losses on such date, to an amount less than the aggregate Scheduled Principal Balance of the related Mortgage Loans as of the related Due Date (such limitation, the “Loss Allocation Limitation”).

(d) The principal portion of any Realized Losses allocated to a Class of Notes shall be allocated among the Notes of such Class (other than the Class X Notes) in proportion to their respective Note Principal Balances. Any allocation of Realized Losses shall be accomplished by reducing the Note Principal Balance of the Notes on the related Payment Date.

(e) Realized Losses shall be allocated on the Payment Date in the month following the month in which such loss was incurred and, in the case of the principal portion thereof, after giving effect to distributions made on such Payment Date.

(f) On each Payment Date, the Securities Administrator shall determine the Subordinate Writedown Amount. Any such Subordinate Writedown Amount shall effect a corresponding reduction in the Note Principal Balance of (i) with respect to the Subordinate Writedown Amount, if prior to the Cross-Over Date, the Class B-6, Class B-5, Class B-4, Class B-3, Class B-2 and Class B-1 Notes, in that order, and (ii) from and after the Cross-Over Date, to the Senior Notes, in accordance with priorities set forth in clause (b) above, in each case, on such Payment Date after giving effect to distributions made on such Payment Date.

(g) The interest portion of any Realized Losses with respect to the Mortgage Loans occurring on or prior to the Cross-Over Date will be borne sequentially to the Class B-6, Class B-5, Class B-4, Class B-3, Class B-2, Class B-1 and Class X Notes, in that order.

(i) In addition, in the event that the Securities Administrator receives any Subsequent Recoveries from the Servicer or Master Servicer, the Securities Administrator shall deposit such funds into the Payment Account pursuant to Section 4.02 of the Sale and Servicing Agreement. If, after taking into account such Subsequent Recoveries, the amount of a Realized Loss is reduced, the amount of such Subsequent Recoveries will be applied to increase the Note Principal Balance of the Notes with the highest payment priority to which Realized Losses have been allocated, but not by more than the amount of Realized Losses previously allocated to that Class or Classes of Notes pursuant to this Section 3.24. The amount of any Subsequent Recoveries following the application set forth in the immediately preceding sentence will be applied to sequentially increase the Note Principal Balance of the Notes, beginning with the Class of Notes with the next highest payment priority, up to the amount of such Realized Losses previously allocated to such Class or Classes of Notes pursuant to this Section 3.24. Holders of such Notes will not be entitled to any payments in respect of Accrued Note Interest on the amount of such increases for any Interest Accrual Period preceding the Payment Date on which such increase occurs. Any such increases shall be applied to the Note Principal Balance of the Notes of such Class in accordance with its respective Percentage Interest.

Except as provided in the next succeeding paragraph of this Section 4.01, the rights of Beneficial Owners with respect to the Notes shall be limited to those established by law and agreements between such Beneficial Owners and the Depository and Depository Participants. Except as provided in Section 4.08 hereof, Beneficial Owners shall not be entitled to definitive certificates for the Notes as to which they are the Beneficial Owners. Requests and directions from, and votes of, the Depository as Holder of the Notes shall not be deemed inconsistent if they are made with respect to different Beneficial Owners. The Securities Administrator may establish a reasonable record date in connection with solicitations of consents from or voting by Noteholders and give notice to the Depository of such record date. Without the consent of the Issuing Entity and the Securities Administrator, no Note may be transferred by the Depository except to a successor Depository that agrees to hold such Note for the account of the Beneficial Owners.

In the event the Depository Trust Company resigns or is removed as Depository, the Depositor may appoint a successor Depository. If no successor Depository has been appointed within 30 days of the effective date of the Depository’s resignation or removal, each Beneficial Owner shall be entitled to certificates representing the Notes it beneficially owns in the manner prescribed in Section 4.08.

The Notes shall, on original issue, be executed on behalf of the Issuing Entity by the Owner Trustee, not in its individual capacity but solely as Owner Trustee, authenticated by the Securities Administrator and delivered by the Securities Administrator to or upon the order of the Issuing Entity.

Section 4.02 Registration of and Limitations on Transfer and Exchange of Notes; Appointment of Securities Administrator to Act as Note Registrar and Certificate Registrar. The Issuing Entity shall cause to be kept at the Corporate Trust Office of the Securities Administrator a Note Register in which, subject to such reasonable regulations as it may prescribe, the Securities Administrator shall provide for the registration of Notes and of transfers and exchanges of Notes as herein provided.

Subject to the restrictions and limitations set forth below, upon surrender for registration of transfer of any Note at the Corporate Trust Office of the Securities Administrator, the Issuing Entity shall execute and the Securities Administrator shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes in authorized initial Note Principal Balances evidencing the same Class and aggregate Percentage Interests.

No transfer, sale, pledge or other disposition of any Privately Offered Note or interest therein shall be made unless that transfer, sale, pledge or other disposition is exempt from the registration and/or qualification requirements of the Securities Act and any applicable state securities laws, or is otherwise made in accordance with the Securities Act and such state securities laws. If a transfer of any Privately Offered Note is to be made without registration under the Securities Act (other than in connection with the initial issuance thereof or a transfer thereof to the Depositor or one of its Affiliates), then the Securities Administrator shall refuse to register such transfer unless (i) it receives (and upon receipt, may conclusively rely upon) a certificate substantially in the form attached as Exhibit C hereto (provided, however, that in the case of the Book-Entry Notes, the Noteholder and the Noteholder’s prospective transferee will be deemed to have made the representations set forth in such certification) or (ii) (a) it receives a written Opinion of Counsel acceptable to and in form and substance satisfactory to the Securities Administrator and the Indenture Trustee that such transfer may be made pursuant to an exemption, describing the applicable exemption and the basis therefor, from the Securities Act and any applicable state securities laws or is being made pursuant to the Securities Act and any applicable state securities laws, which Opinion of Counsel shall not be an expense of the Indenture Trustee, the Owner Trustee, the Depositor, the Seller, the Master Servicer, any Servicer or the Securities Administrator and (b) the transferee executes a representation letter, substantially in the form of Exhibit D attached hereto, and transferor executes a representation letter, substantially in the form of Exhibit E hereto, each acceptable to and in form and substance satisfactory to the Securities Administrator and the Indenture Trustee certifying the facts surrounding such transfer, which representation letters shall not be an expense of the Indenture Trustee, the Owner Trustee, the Depositor, the Seller, the Master Servicer, any Servicer or the Securities Administrator. None of the Issuing Entity, the Depositor, the Indenture Trustee or the Securities Administrator is obligated to register or qualify any Notes under the Securities Act or any other securities law or to take any action not otherwise required under this Indenture to permit the transfer of any Note or interest therein without registration or qualification. Any Noteholder desiring to effect a transfer of Notes or interests therein shall, and does hereby agree to, indemnify the Issuing Entity, the Depositor, the Owner Trustee, the Indenture Trustee and the Securities Administrator 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 or in accordance with any restrictions on transfer set forth in this Indenture. Notwithstanding the foregoing, the provisions of this paragraph shall not apply to the initial transfer of the Notes by the Depositor or any Affiliate thereof.

No transfer, sale, pledge or other disposition of any Privately Offered Notes shall be made, and the Securities Administrator shall refuse to register any such transfer, sale, pledge or other disposition, unless and until the proposed transferor shall have delivered to the Owner Trustee, the Securities Administrator and the Indenture Trustee a certificate substantially in the form of Exhibit F hereto

certifying (i) that, following such transfer, the proposed transferee will either be (a) a Single Owner or (b) a Proportionate Owner, or (ii) that such transfer, either (A) will not cause a TMP Trigger Event or (B) will cause a TMP Trigger Event, in each case, as evidenced by an opinion of nationally recognized tax counsel addressed and provided to the Securities Administrator, the Owner Trustee and the Indenture Trustee (at the expense of the proposed transferor or proposed transferee), and in the case of clause (ii)(B), the REMIC Conversion associated with such TMP Trigger Event (and all conditions precedent thereto, including the contribution to the Issuing Entity or provisions for payment to various parties of certain additional funds by such proposed transferor or proposed transferee pursuant to clauses (iii) and (iv) of Section 11.01(a)) shall have been consummated. Notwithstanding the foregoing, any Privately Offered Notes may be pledged to secure indebtedness and may be the subject of repurchase agreements treated by the Issuing Entity as secured indebtedness for federal income tax purposes, provided that, for the avoidance of doubt, none of the Privately Offered Notes may be transferred by the related lender or repurchase agreement counterparty under any such indebtedness or repurchase agreement upon a default under such indebtedness or repurchase agreement, as applicable, except in accordance with the foregoing. The provisions of this paragraph shall not apply to the initial transfer of the Privately Offered Notes to the Depositor (or an affiliate thereof).

Subject to the foregoing and Section 4.08, Notes may be exchanged for other Notes of like tenor and in authorized initial Note Principal Balances evidencing the same Class and aggregate Percentage Interests upon surrender of the Notes to be exchanged at the Corporate Trust Office of the Securities Administrator. Whenever any Notes are so surrendered for exchange, the Issuing Entity shall execute and the Securities Administrator shall authenticate and deliver the Notes which the Noteholder making the exchange such Noteholder is entitled to receive. Each Note presented or surrendered for registration of transfer or exchange shall (if so required by the Securities Administrator) be duly endorsed by, or be accompanied by a written instrument of transfer in form reasonably satisfactory to the Securities Administrator duly executed by the Holder thereof or his attorney duly authorized in writing with such signature guaranteed by a commercial bank or trust company located or having a correspondent located in the city of New York. Notes delivered upon any such transfer or exchange will evidence the same obligations, and will be entitled to the same rights and privileges, as the Notes surrendered.

Subject to the foregoing and Section 4.08, in connection with a REMIC Conversion, each Noteholder shall surrender all of its Notes to the Securities Administrator in exchange for REMIC Class A Notes pursuant to Section 8.06 of like tenor and in authorized initial note principal balances evidencing the same class designation and aggregate percentage interests upon surrender of the Notes to be exchanged at the Corporate Trust Office of the Securities Administrator. Whenever any Notes are so surrendered for exchange, the Issuing Entity shall execute and the Securities Administrator shall authenticate and deliver the REMIC Class A Notes which the Noteholder making the exchange is entitled to receive. Each Note presented or surrendered for registration of transfer or exchange shall (if so required by the Securities Administrator) be duly endorsed by, or be accompanied by a written instrument of transfer in form reasonably satisfactory to the Securities Administrator, the Holder thereof or his attorney duly authorized in writing with such

signature guaranteed by a commercial bank or trust company located or having a correspondent located in the city of New York. Notes delivered upon any such transfer or exchange will evidence the same obligations in substance, and will be entitled to the same rights and privileges in substance, as the Notes surrendered.

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

The Issuing Entity hereby appoints the Securities Administrator as (i) certificate registrar to keep at its Corporate Trust Office a Certificate Register pursuant to Section 3.08 of the Trust Agreement in which, subject to such reasonable regulations as it may prescribe, the Certificate Registrar shall provide for the registration of Certificates and of transfers and exchanges thereof pursuant to Section 3.03 of the Trust Agreement and (ii) Note Registrar under this Indenture. The Securities Administrator hereby accepts such appointments.

No Person shall become a Holder of Privately Offered Notes until it establishes its non-foreign status by submitting to the Securities Administrator an IRS Form W-9 and the Certificate of Non-Foreign Status set forth in Exhibit G hereto.

Section 4.03 Mutilated, Destroyed, Lost or Stolen Notes. If (i) any mutilated Note is surrendered to the Securities Administrator, or the Securities Administrator receives evidence to its satisfaction of the destruction, loss or theft of any Note, and (ii) there is delivered to the Securities Administrator such security or indemnity as may be required by it to hold the Issuing Entity, the Indenture Trustee and the Securities Administrator harmless, then, in the absence of notice to the Issuing Entity or the Securities Administrator that such Note has been acquired by a bona fide purchaser, and provided that the requirements of Section 8-405 of the UCC are met, the Issuing Entity shall execute, and upon its request the Securities Administrator shall authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Note, a replacement Note; provided, however, that if any such destroyed, lost or stolen Note, but not a mutilated Note, shall have become or within seven days shall be due and payable, instead of issuing a replacement Note, the Issuing Entity may pay such destroyed, lost or stolen Note when so due or payable without surrender thereof. If, after the delivery of such replacement Note or payment of a destroyed, lost or stolen Note pursuant to the proviso to the preceding sentence, a bona fide purchaser of the original Note in lieu of which such replacement Note was issued presents for payment such original Note, the Issuing Entity and the Securities Administrator shall be entitled to recover such replacement Note (or such payment) from the Person to whom it was delivered or any Person taking such replacement Note from such Person to whom such replacement Note was delivered or any assignee of such Person, except a bona fide purchaser, and shall be entitled to recover upon the security or indemnity provided therefor to the extent of any loss, damage, cost or expense incurred by the Issuing Entity, the Indenture Trustee or the Securities Administrator in connection therewith.

Upon the issuance of any replacement Note under this Section 4.03, the Issuing Entity may require the payment by the Holder of such Note of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other reasonable expenses (including the fees and expenses of the Securities Administrator) connected therewith.

Every replacement Note issued pursuant to this Section 4.03 in replacement of any mutilated, destroyed, lost or stolen Note shall constitute an original additional contractual obligation of the Issuing Entity, whether or not the mutilated, destroyed, lost or stolen Note shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Notes duly issued hereunder.

The provisions of this Section 4.03 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes.

Section 4.04 Persons Deemed Owners. Prior to due presentment for registration of transfer of any Note, the Issuing Entity, the Indenture Trustee, the Securities Administrator and any agent of the Issuing Entity or the Securities Administrator may treat the Person in whose name any Note is registered (as of the day of determination) as the owner of such Note for the purpose of receiving payments of principal of and interest, if any, on such Note and for all other purposes whatsoever, whether or not such Note be overdue, and none of the Issuing Entity, the Indenture Trustee, the Securities Administrator or any agent of the Issuing Entity, the Securities Administrator or the Indenture Trustee shall be affected by notice to the contrary.

Section 4.05 Cancellation. All Notes surrendered for payment, registration of transfer, exchange or redemption shall, if surrendered to any Person other than the Securities Administrator, be delivered to the Securities Administrator and shall be promptly cancelled by the Securities Administrator. The Issuing Entity may at any time deliver to the Securities Administrator for cancellation any Notes previously authenticated and delivered hereunder which the Issuing Entity may have acquired in any manner whatsoever, and all Notes so delivered shall be promptly cancelled by the Securities Administrator. No Notes shall be authenticated in lieu of or in exchange for any Notes cancelled as provided in this Section 4.05, except as expressly permitted by this Indenture. All cancelled Notes may be held or disposed of by the Securities Administrator in accordance with its standard retention or disposal policy as in effect at the time unless the Issuing Entity shall direct by an Issuer Request that they be destroyed or returned to it; provided, however, that such Issuer Request is timely and the Notes have not been previously disposed of by the Securities Administrator.

Section 4.06 Book-Entry Notes. The Class I-A-1, Class I-A-2, Class II-A-1, Class II-A-2, Class III-A-1, Class III-A-2, Class IV-A-1 and Class IV-A-2 Notes, upon original issuance, will be issued in the form of typewritten Notes representing the Book-Entry Notes, to be delivered to The Depository Trust Company, the initial Depository, by, or on behalf of, the Issuing Entity. The Notes shall initially be registered on the Note Register in the name of Cede & Co., the nominee of the initial Depository, and no Beneficial Owner will receive a Definitive Note representing such Beneficial Owner’s interest in such Note, except as provided in Section 4.08. With respect to such Notes, unless and until definitive, fully registered Notes (the “Definitive Notes”) have been issued to Beneficial Owners pursuant to Section 4.08:

(i) the provisions of this Section 4.06 shall be in full force and effect;

(ii) the Indenture Trustee and the Securities Administrator shall be entitled to deal with the Depository for all purposes of this Indenture (including the payment of principal of and interest on the Notes and the giving of instructions or directions hereunder) as the sole holder of the Notes, and shall have no obligation to the Beneficial Owners of the Notes;

(iii) to the extent that the provisions of this Section 4.06 conflict with any other provisions of this Indenture, the provisions of this Section 4.06 shall control;

(iv) the rights of Beneficial Owners shall be exercised only through the Depository and shall be limited to those established by law and agreements between such Owners of Notes and the Depository and/or the Depository Participants. Unless and until Definitive Notes are issued pursuant to Section 4.08, the initial Depository will make book-entry transfers among the Depository Participants and receive and transmit payments of principal of and interest on the Notes to such Depository Participants; and

(v) whenever this Indenture requires or permits actions to be taken based upon instructions or directions of Holders of Notes evidencing a specified percentage of the Note Principal Balances of the Notes, the Depository shall be deemed to represent such percentage with respect to the Notes only to the extent that it has received instructions to such effect from Beneficial Owners and/or Depository Participants owning or representing, respectively, such required percentage of the beneficial interest in the Notes and has delivered such instructions to the Securities Administrator and the Indenture Trustee.

None of the Depositor, the Issuing Entity, the Master Servicer, the Seller, the Securities Administrator, the Indenture Trustee and the Owner Trustee shall have any liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in the Book-Entry Notes or for maintaining, supervising or reviewing any records relating to beneficial ownership interests or transfers thereof.

The Class X, Class B-1, Class B-2, Class B-3, Class B-4, Class B-5 and Class B-6 Notes will be registered in full definitive form.

Section 4.07 Notices to Depository. Whenever a notice or other communication to the Note Holders is required under this Indenture, unless and until Definitive Notes shall have been issued to Beneficial Owners pursuant to Section 4.08, the Indenture Trustee or Securities Administrator, as applicable, shall give all such notices and communications specified herein to be given to Holders of the Notes to the Depository, and shall have no obligation to the Beneficial Owners.

Section 4.08 Definitive Notes. If (i) the Depositor advises the Securities Administrator in writing that the Depository is no longer willing or able to properly discharge its responsibilities with respect to the Book-Entry Notes and the Depositor is unable to locate a qualified successor within 30 days or (ii) the Depositor, at its option (with the consent of the Securities Administrator, such consent not to be unreasonably withheld) elects to terminate the book-entry system through the Depository, then the Securities Administrator shall request that the Depository notify all Beneficial Owners of the occurrence of any such event and of the availability of Definitive Notes to Beneficial Owners requesting the same. Upon surrender to the Securities Administrator of the typewritten Notes representing the Book-Entry Notes by the Depository, accompanied by registration instructions, the Issuing Entity shall execute and the Securities Administrator shall authenticate the Definitive Notes in accordance with the instructions of the

Depository. None of the Issuing Entity, the Securities Administrator shall be liable for any delay in delivery of such instructions and may conclusively rely on, and shall be protected in relying on, such instructions. Upon the issuance of Definitive Notes, the Securities Administrator shall recognize the Holders of the Definitive Notes as Noteholders.

In addition, if an Event of Default has occurred and is continuing, each Note Owner materially adversely affected thereby may at its option request a Definitive Note evidencing such Noteholder’s interest in the related Class of Notes. In order to make such request, such Noteholder shall, subject to the rules and procedures of the Depository, provide the Depository or the related Depository Participant with directions for the Securities Administrator to exchange or cause the exchange of the Noteholder’s interest in such Class of Notes for an equivalent interest in fully registered definitive form. Upon receipt by the Securities Administrator of instructions from the Depository directing the Securities Administrator to effect such exchange (such instructions to contain information regarding the Class of Notes and the Note Principal Balance being exchanged, the Depository Participant account to be debited with the decrease, the registered holder of and delivery instructions for the Definitive Note, and any other information reasonably required by the Securities Administrator), (i) the Securities Administrator shall instruct the Depository to reduce the related Depository Participant’s account by the aggregate Note Principal Balance of the Definitive Note, (ii) the Securities Administrator shall execute, authenticate and deliver, in accordance with the registration and delivery instructions provided by the Depository, a Definitive Note evidencing such Noteholder’s interest in such Class of Notes and (iii) the Issuing Entity shall execute and the Securities Administrator shall authenticate a new Book-Entry Note reflecting the reduction in the Note Principal Balance of such Class of Notes by the amount of the Definitive Notes.

Section 4.09 Tax Treatment. The Issuing Entity has entered into this Indenture, and the Class I-A-1, Class I-A-2, Class II-A-1, Class II-A-2, Class III-A-1, Class III-A-2, Class IV-A-1 and Class IV-A-2 Notes shall be issued with the intention that, for federal, state and local income, single business and franchise tax purposes, such Classes of Notes will qualify as indebtedness. The Issuing Entity and the Securities Administrator (in accordance with Section 6.07 hereof), by entering into this Indenture, and each Class I-A-1, Class I-A-2, Class II-A-1, Class II-A-2, Class III-A-1, Class III-A-2, Class IV-A-1 and Class IV-A-2 Noteholder, by its acceptance of its Note (and each Beneficial Owner by its acceptance of an interest in the applicable Book-Entry Note), agree to treat such Classes of Notes for federal, state and local income, single business and franchise tax purposes as indebtedness.

This Indenture shall cease to be of further effect with respect to the Notes except as to (i) rights of registration of transfer and exchange, (ii) substitution of mutilated, destroyed, lost or stolen Notes, (iii) rights of Noteholders to receive payments of principal thereof and interest thereon, (iv) Sections 3.03, 3.04, 3.06, 3.09, 3.17, 3.19 and 3.20, (v) the rights, obligations and immunities of the Indenture Trustee and Securities Administrator hereunder (including the rights of the Securities Administrator under Section 6.08 and the obligations of the Securities Administrator under Section 4.11), and (vi) the rights of Noteholders as beneficiaries hereof with respect to the property so deposited with the Securities Administrator payable to all or any of them, and the Indenture Trustee, on demand of and at the expense of the Issuing Entity, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture with respect to the Notes and shall release and deliver, or cause the related Custodian to deliver, the Collateral to or upon the order of the Issuing Entity, when

(A) Any of the following occur:

(1) all Notes theretofore authenticated and delivered (other than (i) Notes that have been destroyed, lost or stolen and that have been replaced or paid as provided in Section 4.03 hereof and (ii) Notes for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Issuing Entity and thereafter repaid to the Issuing Entity or discharged from such trust, as provided in Section 3.03) have been delivered to the Securities Administrator for cancellation;

(2) all Notes not theretofore delivered to the Securities Administrator for cancellation

have become due and payable,

will become due and payable at the Final Scheduled Payment Date within one year, or

(C) the Issuing Entity has delivered to the Indenture Trustee an Officer’s Certificate and an Opinion of Counsel, each meeting the applicable requirements of Section 10.01 hereof, each stating that all conditions precedent herein provided for

relating to the satisfaction and discharge of this Indenture have been complied with and, if the Opinion of Counsel relates to a deposit made in connection with Section 4.10(A)(2)b. above, such opinion shall further be to the effect that such deposit will constitute an “in-substance defeasance” within the meaning of Revenue Ruling 85-42, 1985-1 C.B. 36, and in accordance therewith, the Issuing Entity will be the owner of the assets deposited in trust for federal income tax purposes.

Section 4.11 Application of Trust Money. All monies deposited with the Securities Administrator pursuant to Section 4.10 hereof shall be held in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any paying agent or the certificate paying agent as designee of the Issuing Entity, as the Securities Administrator may determine, to the Holders of Securities, of all sums due and to become due thereon for principal and interest or otherwise; but such monies need not be segregated from other funds except to the extent required herein or required by law.

Section 4.12 [Reserved].

Section 4.13 Repayment of Monies Held by Securities Administrator. In connection with the satisfaction and discharge of this Indenture with respect to the Notes, all monies then held by any Person other than the Securities Administrator under the provisions of this Indenture with respect to such Notes shall, upon demand of the Issuing Entity, be paid to the Securities Administrator to be held and applied according to Section 3.03 and thereupon such Person shall be released from all further liability with respect to such monies.

Section 4.14 Temporary Notes. Pending the preparation of any Definitive Notes, the Issuing Entity may execute and upon its written direction, the Securities Administrator may authenticate and make available for delivery, temporary Notes that are printed, lithographed, typewritten, photocopied or otherwise produced, in any denomination, substantially of the tenor of the Definitive Notes in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Notes may determine, as evidenced by their execution of such Notes.

If temporary Notes are issued, the Issuing Entity will cause Definitive Notes to be prepared without unreasonable delay. After the preparation of the Definitive Notes, the temporary Notes shall be exchangeable for Definitive Notes upon surrender of the temporary Notes at the Corporate Trust Office of the Securities Administrator, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Notes, the Issuing Entity shall execute and the Securities Administrator shall authenticate and make available for delivery, in exchange therefor, Definitive Notes of authorized denominations and of like tenor, class and aggregate principal amount. Until so exchanged, such temporary Notes shall in all respects be entitled to the same benefits under this Indenture as Definitive Notes.

Section 4.15 ERISA Treatment.

No Note may be sold or transferred to a Person unless such Person certifies in the form of Exhibit E to this Agreement (which in the case of the Book-Entry Notes, such Person will be deemed to have made the representations contained in such certificates, respectively), which certification the Securities Administrator may rely upon without further inquiry or investigation, that:

(i) Such Person is neither (A) an employee benefit plan or other retirement arrangement, including individual retirement accounts and annuities, Keogh plans and collective investment funds and separate accounts in which such plans, accounts or arrangements are invested, including, without limitation, insurance company general accounts, that is subject to ERISA or Section 4975 of the Code (each, a “Plan”), nor (B) any Person who is directly or indirectly purchasing such Note or interest therein on behalf of, as named fiduciary of, as trustee of, or with “Plan Assets” (as defined under the DOL Regulation at 29 C.F.R. Section 2510.3-101) of a Plan;

(ii) Except in the case of a Class X Note or Class B Note (A) such Person is a Plan or a Person purchasing such Note with Plan Assets and represents that, as of the date of the transfer, the Notes are rated investment grade or better, (B) such Person believes that the Notes are properly treated as indebtedness without substantial equity features for purposes of the DOL Regulations, and agrees to so treat the Notes, and (C) the acquisition and holding of the Note will not give rise to a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code; or

(iii) Such Person has provided the Securities Administrator with an Opinion of Counsel, which Opinion of Counsel will not be at the expense of the Trust Estate, the Depositor, the Issuing Entity, the Owner Trustee, the Indenture Trustee or the Securities Administrator, which establishes to the satisfaction of the Securities Administrator that the purchase, holding and transfer of such Note or interest therein is permissible under applicable law, will not constitute or result in a non-exempt prohibited transaction under ERISA or Section 4975 of the Code and will not subject the Issuing Entity, the Owner Trustee, the Indenture Trustee, the Securities Administrator, the Depositor or the Indenture Trustee to any obligation in addition to those undertaken in the Indenture.

Notwithstanding the foregoing, neither an Opinion of Counsel nor a certification will be required in connection with the initial transfer of any such Note by the Depositor to an Affiliate of the Depositor (in which case, the Depositor or any Affiliate thereof shall be deemed to have represented that such Affiliate is not a Plan or any Person investing “plan assets” of any Plan) and the Securities Administrator shall be entitled to conclusively rely upon a representation (which, upon the request of the Securities Administrator, shall be a written representation) from the Depositor of the status of such transferee as an Affiliate of the Depositor.

ARTICLE V

DEFAULT AND REMEDIES

Section 5.01 Events of Default. The Issuing Entity shall deliver to the Indenture Trustee, within five days after learning of the occurrence of a Default, written notice in the form of an Officer’s Certificate of any event which with the giving of notice and the lapse of time would become an Event of Default under clause (ii), (iii) or (iv) of the definition of “Event of Default”, its status and what action the Issuing Entity is taking or proposes to take with respect thereto. The Indenture Trustee shall not be deemed to have knowledge of any Default or Event of Default unless a Responsible Officer has actual knowledge thereof or unless written notice of such Default or Event of Default is received by a Responsible Officer and such notice references the Notes, the Trust Estate or this Indenture.

Section 5.02 Acceleration of Maturity; Rescission and Annulment. If an Event of Default should occur and be continuing, then and in every such case the Indenture Trustee at the written direction of the Holders of Notes representing not less than a majority of the aggregate Note Principal Balance of the Notes may declare the Notes to be immediately due and payable, by a notice in writing to the Issuing Entity (and to the Indenture Trustee if such notice is given by Noteholders), and upon any such declaration the unpaid Note Principal Balance of the Notes, together with accrued and unpaid interest thereon through the date of acceleration, shall become immediately due and payable.

At any time after such declaration of acceleration of maturity with respect to an Event of Default has been made and before a judgment or decree for payment of the money due has been obtained by the Indenture Trustee as hereinafter in this Article V provided, Holders of the Notes representing not less than a majority of the aggregate Note Principal Balance of each Class of Notes, by written notice to the Issuing Entity and the Indenture Trustee, may, subject to Section 5.12, waive the related Event of Default and rescind and annul such declaration and its consequences if:

(i) the Issuing Entity has paid or deposited with the Indenture Trustee or Securities Administrator a sum sufficient to pay:

(A) all payments of principal of and interest on the Notes and all other amounts that would then be due hereunder or under the Notes if the Event of Default giving rise to such acceleration had not occurred;

(B) all sums paid or advanced by the Indenture Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Indenture Trustee and its agents and counsel; and

(ii) all Events of Default, other than the nonpayment of the principal of the Notes that has become due solely by such acceleration, have been cured or waived as provided in Section 5.12.

No such rescission shall affect any subsequent default or impair any right consequent thereto.

Section 5.03 Collection of Indebtedness and Suits for Enforcement by Indenture Trustee.

(a) The Issuing Entity covenants that if (i) default is made in the payment of any interest on any Note when the same becomes due and payable, and such default continues for a period of five days, or (ii) default is made in the payment of the principal of or any installment of the principal of any Note when the same becomes due and payable, the Issuing Entity shall, upon demand of the Indenture Trustee, acting at the direction of the Holders of a majority of the aggregate Note Principal Balances of the Notes, pay to the Securities Administrator, for the benefit of the Holders of Notes, the whole amount then due and payable on the Notes for principal and interest, with interest at the applicable Note Interest Rate upon the overdue principal, and in addition thereto such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Indenture Trustee and its agents and counsel.

(b) In case the Issuing Entity shall fail forthwith to pay such amounts upon such demand, the Indenture Trustee, in its own name and as trustee of an express trust, subject to the provisions of Section 10.15 hereof, may institute a Proceeding for the collection of the sums so due and unpaid, and may prosecute such Proceeding to judgment or final decree, and may enforce the same against the Issuing Entity or other obligor upon the Notes and collect in the manner provided by law out of the property of the Issuing Entity or other obligor upon the Notes, wherever situated, the monies adjudged or decreed to be payable.

(c) If an Event of Default occurs and is continuing, the Indenture Trustee, subject to the provisions of Section 10.15 hereof, may, as more particularly provided in Section 5.04 hereof, in its discretion, proceed to protect and enforce its rights and the rights of the Noteholders by such appropriate Proceedings as directed in writing by the Holders of a majority of the aggregate Note Principal Balances of each Class of Notes, to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy or legal or equitable right vested in the Indenture Trustee by this Indenture or by law.

(d) In case there shall be pending, relative to the Issuing Entity or any other obligor upon the Notes or any Person having or claiming an ownership interest in the Trust Estate, Proceedings under Title 11 of the United States Code or any other applicable federal or state bankruptcy, insolvency or other similar law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or similar official shall have been appointed for or taken possession of the Issuing Entity or its property or such other obligor or Person, or in case of any other comparable judicial Proceedings relative to the Issuing Entity or other obligor upon the Notes, or to the creditors or property of the Issuing Entity or such other obligor, the Indenture Trustee, as directed in writing by the Holders of a majority of the aggregate Note Principal Balances of each Class of Notes, irrespective of whether the principal of any Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Indenture Trustee shall have made any demand pursuant to the provisions of this Section, shall be entitled and empowered, by intervention in such Proceedings or otherwise:

(i) to file and prove a claim or claims for the whole amount of principal and interest owing and unpaid in respect of the Notes and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Indenture Trustee (including any claim for reasonable compensation to the Indenture Trustee and each predecessor Indenture Trustee, and their respective agents, attorneys and counsel, and for reimbursement of all expenses and liabilities incurred, and all advances made, by the Indenture Trustee and each predecessor Indenture Trustee, except as a result of negligence, willful misconduct or bad faith) and of the Noteholders allowed in such Proceedings;

(ii) unless prohibited by applicable law and regulations, to vote on behalf of the Holders of Notes in any election of a trustee, a standby trustee or Person performing similar functions in any such Proceedings;

(iii) to collect and receive any monies or other property payable or deliverable on any such claims and to distribute all amounts received with respect to the claims of the Noteholders and of the Indenture Trustee on their behalf, and

(iv) to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Indenture Trustee or the Holders of Notes allowed in any judicial proceedings relative to the Issuing Entity, its creditors and its property;

and any trustee, receiver, liquidator, custodian or other similar official in any such Proceeding is hereby authorized by each of such Noteholders to make payments to the Securities Administrator, and, in the event that the Indenture Trustee shall consent to the making of payments directly to such Noteholders, to pay to the Indenture Trustee such amounts as shall be sufficient to cover reasonable compensation to the Indenture Trustee, each predecessor Indenture Trustee and their respective agents, attorneys and counsel, and all other expenses and liabilities incurred, and all advances made, by the Indenture Trustee and each predecessor Indenture Trustee.

(e) Nothing herein contained shall be deemed to authorize the Indenture Trustee to authorize or consent to or vote for or accept or adopt on behalf of any Noteholder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof or to authorize the Indenture Trustee to vote in respect of the claim of any Noteholder in any such proceeding except, as aforesaid, to vote for the election of a trustee in bankruptcy or similar Person.

(f) All rights of action and of asserting claims under this Indenture, or under any of the Notes, may be enforced by the Indenture Trustee without the possession of any of the Notes or the production thereof in any trial or other Proceedings relative thereto, and any such action or proceedings instituted by the Indenture Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment, subject to the payment of the expenses, disbursements and compensation of the Indenture Trustee, each predecessor Indenture Trustee and their respective agents and attorneys, shall be for the ratable benefit of the Holders of the Notes, subject to Section 5.05 hereof.

In any Proceedings brought by the Indenture Trustee (and also any Proceedings involving the interpretation of any provision of this Indenture to which the Indenture Trustee shall be a party), the Indenture Trustee shall be held to represent all the Holders of the Notes, and it shall not be necessary to make any Noteholder a party to any such Proceedings.

Section 5.04 Remedies; Priorities. (a) If an Event of Default shall have occurred and be continuing and if an acceleration has been declared and not rescinded pursuant to Section 5.02 hereof, the Indenture Trustee, subject to the provisions of Section 10.15 hereof, may, and shall, at the written direction of the Holders of a majority of the aggregate Note Principal Balances of the Notes, do one or more of the following (subject to Section 5.05 hereof):

(i) institute Proceedings in its own name and as trustee of an express trust for the collection of all amounts then payable on the Notes or under this Indenture with respect thereto, whether by declaration or otherwise, enforce any judgment obtained, and collect from the Issuing Entity and any other obligor upon such Notes monies adjudged due;

(ii) institute Proceedings from time to time for the complete or partial foreclosure of this Indenture with respect to the Trust Estate;

(iii) exercise any remedies of a secured party under the UCC and take any other appropriate action to protect and enforce the rights and remedies of the Indenture Trustee and the Holders of the Notes; and

(iv) sell the Trust Estate or any portion thereof or rights or interest therein, at one or more public or private sales called and conducted in any manner permitted by law;

provided, however, that the Indenture Trustee may not sell or otherwise liquidate the Trust Estate following an Event of Default, unless (A) the Indenture Trustee obtains the consent of the Holders of 100% of the aggregate Note Principal Balance of the Notes then outstanding, (B) the proceeds of such sale or liquidation distributable to the Holders of the Notes are sufficient to discharge in full all amounts then due and unpaid upon such Notes for principal and interest or (C) the Indenture Trustee determines that the Mortgage Loans will not continue to provide sufficient funds for the payment of principal of and interest on the applicable Notes as they would have become due if the Notes had not been declared due and payable, and the Indenture Trustee obtains the consent of the Holders of 66 2/3% of the aggregate Note Principal Balance of each Class of Notes then outstanding, voting separately. In determining such sufficiency or insufficiency with respect to clause (B) and (C), the Indenture Trustee may, but need not, obtain and rely upon an opinion (obtained at the expense of the Trust) of an Independent investment banking or accounting firm of national reputation as to the feasibility of such proposed action and as to the sufficiency of the Trust Estate for such purpose. Notwithstanding the foregoing, any Sale of the Trust Estate shall be made subject to the continued servicing of the Mortgage Loans by the Servicer (other than any Servicer as to which an Event of Servicer Termination has occurred and is continuing) as provided in the Sale and Servicing Agreement.

(b) If the Indenture Trustee or the Securities Administrator collects any money or property pursuant to this Article V, the Securities Administrator shall pay out the money or property in the following order:

FIRST: to the Indenture Trustee, the Securities Administrator, Master Servicer, the Owner Trustee, the Custodians and the Servicers for amounts due and not previously paid pursuant to the Indenture and the other Basic Documents,

SECOND: to the Noteholders, in the manner and priority set forth under Section 3.03 of this Agreement, and

THIRD: to the Securities Administrator for distribution to the holders of the Certificates.

The Securities Administrator may fix a record date and Payment Date for any payment to Noteholders pursuant to this Section 5.04. At least 15 days before such record date, the Securities Administrator shall mail to each Noteholder a notice that states the record date, the Payment Date and the amount to be paid.

Section 5.05 Optional Preservation of the Trust Estate. If the Notes have been declared to be due and payable under Section 5.02 following an Event of Default and such declaration and its consequences have not been rescinded and annulled, the Indenture Trustee may elect to take and maintain possession of the Trust Estate. It is the desire of the parties hereto and the Noteholders that there be at all times sufficient funds for the payment of principal of and interest on the Notes and other obligations of the Issuing Entity, and the Indenture Trustee shall take such desire into account when determining whether or not to take and maintain possession of the Trust Estate. In determining whether to take and maintain possession of the Trust Estate, the Indenture Trustee may, but need not, obtain and rely upon an opinion of an Independent investment banking or accounting firm of national reputation as to the feasibility of such proposed action and as to the sufficiency of the Trust Estate for such purpose.

Section 5.06 Limitation of Suits. So long as the Majority Certificateholder owns 100% of the Securities, no Holder of any Note shall have any right to institute any Proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder. No Holder of any Note shall have any right to institute any Proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless and subject to the foregoing and the provisions of Section 10.15 hereof:

(i) such Holder has previously given written notice to the Indenture Trustee of a continuing Event of Default;

(ii) the Holders of not less than 25% of the aggregate Note Principal Balance of the Notes have made a written request to the Indenture Trustee to institute such Proceeding in respect of such Event of Default in its own name as Indenture Trustee hereunder;

(iii) such Holder or Holders have offered to the Indenture Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in complying with such request;

(iv) the Indenture Trustee, for 60 days after its receipt of such notice of request and offer of indemnity, has failed to institute such Proceedings; and

(v) no direction inconsistent with such written request has been given to the Indenture Trustee during such 60-day period by the Holders of a majority of the Note Principal Balances of the Notes.

It is understood and intended that no one or more Holders of Notes shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other Holders of Notes or to obtain or to seek to obtain priority or preference over any other Holders or to enforce any right under this Indenture, except in the manner herein provided.

No Holder of any Note shall have any right to institute any Proceeding, judicial or otherwise with respect to a TMP Trigger Event, with respect to the meeting of the conditions for a REMIC Conversion or with respect to a REMIC Conversion.

Subject to the last paragraph of Section 5.11 herein, in the event the Indenture Trustee shall receive conflicting or inconsistent requests and indemnity from two or more Holders of Notes, each representing less than a majority of the Note Principal Balances of the Notes, the Indenture Trustee shall take such action as requested by the Holders representing the highest amount (in the aggregate) of the Note Principal Balances, notwithstanding any other provisions of this Indenture.

Section 5.07 Unconditional Rights of Noteholders To Receive Principal and Interest. Notwithstanding any other provisions in this Indenture, the Holder of any Note shall have the right, which is absolute and unconditional, to receive payment of the principal of and interest, if any, on such Note on or after the respective due dates thereof expressed in such Note or in this Indenture and to institute suit for the enforcement of any such payment, and such right shall not be impaired without the consent of such Holder. Notwithstanding the foregoing, in the event of a REMIC Conversion, Holders of Notes shall receive in a mandatory exchange for such Notes, the corresponding classes of REMIC Class A Notes and REMIC Privately Offered Certificates, as further described in Section 8.06 hereof, whose principal and interest entitlements shall not be determined by this Indenture but rather by the provisions of the REMIC Class A Indenture and Pooling and Servicing Agreement, as applicable.

Section 5.08 Restoration of Rights and Remedies. If the Indenture Trustee or any Noteholder has instituted any Proceeding to enforce any right or remedy under this Indenture and such Proceeding has been discontinued or abandoned for any reason or has been determined adversely to the Indenture Trustee or to such Noteholder, then and in every such case the Issuing Entity, the Indenture Trustee and the Noteholders shall, subject to any determination in such Proceeding, be restored severally and respectively to their former positions hereunder, and thereafter all rights and remedies of the Indenture Trustee and the Noteholders shall continue as though no such Proceeding had been instituted.

Section 5.09 Rights and Remedies Cumulative. No right or remedy herein conferred upon or reserved to the Indenture Trustee or to the Noteholders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

Section 5.10 Delay or Omission Not a Waiver. No delay or omission of the Indenture Trustee or any Holder of any Note to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article V or by law to the Indenture Trustee or to the Noteholders may be exercised from time to time, and as often as may be deemed expedient, by the Indenture Trustee or by the Noteholders, as the case may be.

Section 5.11 Control By Noteholders. The Holders of a majority of the aggregate Note Principal Balances of Notes shall have the right to direct the time, method and place of conducting any Proceeding for any remedy available to the Indenture Trustee with respect to the Notes or exercising any trust or power conferred on the Indenture Trustee; provided that:

(i) such direction shall not be in conflict with any rule of law or with this Indenture;

(ii) any direction to the Indenture Trustee to sell or liquidate the Trust Estate shall be by Holders of Notes representing not less than 100% of the aggregate Note Principal Balance of the Notes or the Holders of 66 2/3% of the aggregate Note Principal Balance of each Class of Notes then outstanding, voting separately as set forth in Section 5.04(a) hereof; and

(iii) the Indenture Trustee may take any other action deemed proper by the Indenture Trustee that is not inconsistent with such direction of the Holders of Notes representing a majority of the Note Principal Balances of the Notes.

Notwithstanding the rights of Noteholders set forth in this Section 5.11 the Indenture Trustee need not take any action that it determines might involve it in liability.

Section 5.12 Waiver of Past Defaults. Prior to the declaration of the acceleration of the maturity of the Notes as provided in Section 5.02 hereof, the Holders of Notes representing not less than a majority of the aggregate Note Principal Balance of each Class of Notes may waive any past Event of Default and its consequences except an Event of Default (a) with respect to payment of principal of or interest on any of the Notes, or (b) in respect of a covenant or provision hereof which cannot be modified or amended without the consent of the Holder of each Note. In the case of any such waiver, the Issuing Entity, the Indenture Trustee and the Holders of the Notes shall be restored to their former positions and rights hereunder, respectively, but no such waiver shall extend to any subsequent or other Event of Default or impair any right consequent thereto.

Upon any such waiver, any Event of Default arising therefrom shall be deemed to have been cured and not to have occurred for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Event of Default or impair any right consequent thereto.

Section 5.13 Undertaking for Costs. All parties to this Indenture agree, and each Holder of any Note and each Beneficial Owner of any interest therein by such Holder’s or Beneficial Owner’s acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the

Indenture Trustee for any action taken, suffered or omitted by it as Indenture Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section 5.13 shall not apply to (a) any suit instituted by the Indenture Trustee, (b) any suit instituted by any Noteholder, or group of Noteholders, in each case holding in the aggregate more than 10% of the Note Principal Balances of the Notes or (c) any suit instituted by any Noteholder for the enforcement of the payment of principal of or interest on any Note on or after the respective due dates expressed in such Note and in this Indenture.

Section 5.14 Waiver of Stay or Extension Laws. The Issuing Entity covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead or in any manner whatsoever, claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and the Issuing Entity (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it shall not hinder, delay or impede the execution of any power herein granted to the Indenture Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

Section 5.15 Sale of Trust Estate. (a) The power to effect any sale or other disposition (a “Sale”) of any portion of the Trust Estate pursuant to Section 5.04 hereof is expressly subject to the provisions of Sections 5.05 and 5.11(ii) hereof and this Section 5.15. The power to effect any such Sale shall not be exhausted by any one or more Sales as to any portion of the Trust Estate remaining unsold, but shall continue unimpaired until the entire Trust Estate shall have been sold or all amounts payable on the Notes and under this Indenture shall have been paid. The Indenture Trustee may from time to time postpone any public Sale by public announcement made at the time and place of such Sale. The Indenture Trustee hereby expressly waives its right to any amount fixed by law as compensation for any Sale.

(b) The Indenture Trustee shall not in any private Sale sell the Trust Estate, or any portion thereof, unless

(1) the Holders of all Notes consent to or direct the Indenture Trustee to make, such Sale, or

(2) the proceeds of such Sale would be not less than the entire amount which would be payable to the Noteholders under the Notes, in full payment thereof in accordance with Section 5.02 hereof, on the Payment Date next succeeding the date of such Sale, or

(3) the Indenture Trustee determines that the conditions for retention of the Trust Estate set forth in Section 5.05 hereof cannot be satisfied (in making any such determination, the Indenture Trustee may rely upon an opinion of an Independent investment banking firm obtained and delivered as provided in Section 5.05 hereof), and the Holders of Notes representing at least 100% of the Note Principal Balances of the Notes consent to such Sale; or

(4) such Sale occurs following notice of a TMP Trigger Event in accordance with the terms and conditions described in Section 11.01 of this Indenture.

The purchase by the Indenture Trustee of all or any portion of the Trust Estate at a private Sale shall not be deemed a Sale or other disposition thereof for purposes of this Section 5.15(b).

(c) Subject to this Section 5.15, unless the Holders representing at least 100% of the aggregate Note Principal Balance of the Notes or the Holders of 66 2/3% of the aggregate Note Principal Balance of each Class of Notes then outstanding, voting separately as set forth in Section 5.04(a) hereof, have otherwise consented or directed the Indenture Trustee, at any public Sale of all or any portion of the Trust Estate at which a minimum bid equal to or greater than the amount described in paragraph (2) of subsection (b) of this Section 5.15 has not been established by the Indenture Trustee and no Person bids an amount equal to or greater than such amount, the Indenture Trustee, as trustee for the benefit of the Holders of the Notes, shall bid an amount (which shall include the Indenture Trustee’s right, in its capacity as Indenture Trustee, to credit bid) at least $1.00 more than the highest other bid in order to preserve the Trust Estate on behalf of the Noteholders.

(d) In connection with a Sale of all or any portion of the Trust Estate,

(1) any Holder or Holders of Notes may bid for and purchase the property offered for sale, and upon compliance with the terms of sale may hold, retain and possess and dispose of such property, without further accountability, and may, in paying the purchase money therefor, deliver any Notes or claims for interest thereon in lieu of cash up to the amount which shall, upon distribution of the net proceeds of such sale, be payable thereon, and such Notes, in case the amounts so payable thereon shall be less than the amount due thereon, shall be returned to the Holders thereof after being appropriately stamped to show such partial payment;

(2) the Indenture Trustee may bid for and acquire the property offered for Sale in connection with any Sale thereof, and, subject to any requirements of, and to the extent permitted by, applicable law in connection therewith, may purchase all or any portion of the Trust Estate in a private sale, and, in lieu of paying cash therefor, may make settlement for the purchase price by crediting the gross Sale price against the sum of (A) the amount which would be distributable to the Holders of the Notes and Holders of Certificates on the Payment Date next succeeding the date of such Sale and (B) the expenses of the Sale and of any Proceedings in connection therewith which are reimbursable to it, without being required to produce the Notes in order to complete any such Sale or in order for the net Sale price to be credited against such Notes, and any property so acquired by the Indenture Trustee shall be held and dealt with by it in accordance with the provisions of this Indenture;

(3) the Indenture Trustee shall execute and deliver an appropriate instrument of conveyance, prepared by the Issuing Entity and satisfactory to the Indenture Trustee, transferring its interest in any portion of the Trust Estate in connection with a Sale thereof; and

(4) the Indenture Trustee is hereby irrevocably appointed the agent and attorney-in-fact of the Issuing Entity to transfer and convey its interest in any portion of the Trust Estate in connection with a Sale thereof, and to take all action necessary to effect such Sale.

(e) So long as the Majority Certificateholder owns 100% of the Securities, the Majority Certificateholder shall not consent to any Sale of the Trust Estate as set forth herein other than a Sale following a TMP Trigger Event.

Section 5.16 Action on Notes. The Indenture Trustee’s right to seek and recover judgment on the Notes or under this Indenture shall not be affected by the seeking, obtaining or application of any other relief under or with respect to this Indenture. Neither the lien of this Indenture nor any rights or remedies of the Indenture Trustee or the Noteholders shall be impaired by the recovery of any judgment by the Indenture Trustee against the Issuing Entity or by the levy of any execution under such judgment upon any portion of the Trust Estate or upon any of the assets of the Issuing Entity. Any money or property collected by the Indenture Trustee or the Securities Administrator shall be applied by the Securities Administrator in accordance with Section 5.04(b) hereof.

ARTICLE VI

THE INDENTURE TRUSTEE AND THE SECURITIES ADMINISTRATOR

Section 6.01 Duties of Indenture Trustee and Securities Administrator. (a) If an Event of Default has occurred and is continuing, the Indenture Trustee shall exercise the rights and powers vested in it by this Indenture 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.

(b) Except during the continuance of an Event of Default of which the Indenture Trustee has actual knowledge or has received written notice, in the case of the Indenture Trustee and, at any time, in the case of the Securities Administrator:

(i) the Indenture Trustee and the Securities Administrator undertakes to perform such duties and only such duties as are specifically set forth in this Indenture and the other Basic Documents to which it is a party and no implied covenants or obligations shall be read into this Indenture and the other Basic Documents against the Indenture Trustee or the Securities Administrator; and

(ii) in the absence of bad faith on its part, the Indenture Trustee and the Securities Administrator may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates, reports, documents, Issuer Requests or other instruments or opinions furnished to each of the Indenture Trustee and the Securities Administrator and conforming to the requirements of this Indenture or the other Basic Documents; however, the Indenture Trustee and the Securities Administrator shall examine the certificates, reports, documents, Issuer Requests or other instruments and opinions to determine whether or not they conform on their face to the requirements of this Indenture.

(c) The Indenture Trustee and the Securities Administrator may not be relieved from liability for each of its own negligent action, its own negligent failure to act or its own willful misconduct, except that:

(i) this paragraph does not limit the effect of paragraph (b) of this Section 6.01;

(ii) neither the Indenture Trustee nor the Securities Administrator shall not be liable for any error of judgment made in good faith by a Responsible Officer unless it is proved that the Indenture Trustee or the Securities Administrator, as applicable, was negligent in ascertaining the pertinent facts; and

(f) No provision of this Indenture shall require the Indenture Trustee or the Securities Administrator to expend or risk its own funds or otherwise incur financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers, if it shall have reasonable grounds to believe that repayment of such funds or indemnity satisfactory to it against such risk or liability is not reasonably assured to it.

(g) Every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Indenture Trustee shall be subject to the provisions of this Section.

(h) The Indenture Trustee shall not be deemed to have notice or knowledge of any Default or Event of Default unless a Responsible Officer of the Indenture Trustee has actual knowledge thereof or unless written notice of any such event that is in fact an Event of Default or Default is received by the Indenture Trustee at its Corporate Trust Office and such notice references the Notes or Certificates generally, the Issuing Entity, the Trust Estate or this Indenture.

(i) The Securities Administrator (i) may not be an originator, Master Servicer, Servicer, the Depositor or an affiliate of the Depositor unless the Securities Administrator is a bank or trust company organized under the laws of the United States or any state thereof, (ii) must be authorized to exercise corporate trust powers under the laws of its jurisdiction of organization, and (iii) must be rated at least “A/F1” by Fitch, if Fitch is a Rating Agency, or the equivalent rating by S&P or Moody’s. If no successor Securities Administrator shall have been appointed and shall have accepted appointment within 60 days after the Securities Administrator ceases to be the Securities Administrator pursuant to Section 6.09, then the Indenture Trustee when acting as Securities Administrator shall perform the duties of the Securities Administrator pursuant to this Agreement. The Indenture Trustee shall be entitled to all compensation, reimbursement of expenses and indemnifications that the Securities Administrator would have been entitled to if it had continued to act hereunder, provided, however, that the Indenture Trustee shall not be (i) liable for any acts or omissions of the Securities Administrator, or (ii) responsible for expenses of the Securities Administrator. The Indenture Trustee shall notify the Rating Agencies of any change of Securities Administrator.

Section 6.02 Rights of Indenture Trustee and Securities Administrator.

The Indenture Trustee and the Securities Administrator need not investigate any fact or matter stated in the document.

(b) Before the Indenture Trustee or the Securities Administrator acts or refrains from acting, it may require an Officer’s Certificate or an Opinion of Counsel. Neither the Indenture Trustee nor the Securities Administrator shall be liable for any action it takes or omits to take in good faith in reliance on and in accordance with an Officer’s Certificate or Opinion of Counsel.

(e) For the limited purpose of effecting any action to be undertaken by each of the Indenture Trustee and the Securities Administrator, but not specifically as a duty of the Indenture Trustee or the Securities Administrator in the Indenture, each of the Indenture Trustee and the Securities Administrator may execute any of the trusts or powers hereunder or perform any duties hereunder, either directly or by or through agents, attorneys, custodians or nominees appointed with due care, and shall not be responsible for any willful misconduct or negligence on the part of any agent, attorney, custodian or nominee so appointed.

(f) The Securities Administrator or its Affiliates are permitted to receive additional compensation that could be deemed to be in the Securities Administrator’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. Such compensation shall not be considered an amount that is reimbursable or payable to the Securities Administrator (i) as part of the compensation hereunder or (ii) out of Available Funds.

(g) Anything in this Indenture to the contrary notwithstanding, in no event shall the Indenture Trustee or the Securities Administrator be liable for special, indirect or consequential loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Indenture Trustee or the Securities Administrator has been advised of the likelihood of such loss or damage and regardless of the form of action.

(h) None of the Securities Administrator, the Issuing Entity or the Indenture Trustee shall be responsible for the acts or omissions of the other, it being understood that this Indenture shall not be construed to render them partners, joint venturers or agents of one another.

(i) Neither the Indenture Trustee nor the Securities Administrator shall be required to expend or risk its own funds or otherwise incur financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if there is reasonable ground for believing that the repayment of such funds or indemnity reasonably satisfactory to it against such risk or liability is not reasonably assured to it, and none of the provisions contained in this Indenture shall in any event require the Indenture Trustee or the Securities Administrator to perform, or be responsible for the manner of performance of, any of the obligations of the Master Servicer under the Wells Fargo Servicing Agreement, except during such time, if any, as the Indenture Trustee shall be the successor to, and be vested with the rights, duties, powers and privileges of, the Master Servicer in accordance with the terms of the Wells Fargo Servicing Agreement.

(j) Except for those actions that the Indenture Trustee or the Securities Administrator are required to take hereunder, neither the Indenture Trustee nor the Securities Administrator shall have any obligation or liability to take any action or to refrain from taking any action hereunder in the absence of written direction as provided hereunder.

(k) Neither the Indenture Trustee nor the Securities Administrator shall be under any obligation to exercise any of the trusts or powers vested in it by this Indenture, other than its obligation to give notices pursuant to this Indenture, or to institute, conduct or defend any litigation hereunder or in relation hereto at the request, order or direction of any of the Noteholders pursuant to the provisions of this Indenture, unless such Noteholders shall have offered to the Indenture Trustee or the Securities Administrator, as applicable, reasonable security or indemnity against the costs, expenses and liabilities which may be incurred therein or thereby. Nothing contained herein shall, however, relieve the Indenture Trustee of the obligation, upon the occurrence of an Event of Default of which a Responsible Officer of the Indenture Trustee has actual knowledge (which has not been cured or waived), to exercise such of the rights and powers vested in it by this Indenture and to use the same degree of care and skill in their exercise as a prudent person would exercise under the circumstances in the conduct of his own affairs.

(l) Neither the Indenture Trustee nor the Securities Administrator shall be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, approval, bond or other paper or document, unless requested in writing to do so by Holders of Notes representing not less than 25% of the Note Principal Balance of the Notes and provided that the payment within a reasonable time to the Indenture Trustee or the Securities Administrator, as applicable, of the costs, expenses or liabilities likely to be incurred by it in the making of such investigation is, in the opinion of the Indenture Trustee or the Securities Administrator, as applicable, reasonably assured to the Indenture Trustee by the security afforded to it by the terms of this Indenture. The Indenture Trustee or the Securities Administrator may require reasonable indemnity against such expense or liability as a condition to taking any such action. The reasonable expense of every such examination shall be paid by the Noteholders requesting the investigation.

(m) Should the Indenture Trustee or the Securities Administrator deem the nature of any action required on its part to be unclear, the Indenture Trustee or the Securities Administrator, respectively, may require prior to such action that it be provided by the Depositor with reasonable further instructions.

(n) The right of the Indenture Trustee or the Securities Administrator to perform any discretionary act enumerated in this Indenture shall not be construed as a duty, and neither the Indenture Trustee nor the Securities Administrator shall be accountable for other than its negligence or willful misconduct in the performance of any such act.

(o) Neither the Indenture Trustee nor the Securities Administrator shall be required to give any bond or surety with respect to the execution of the trust created hereby or the powers granted hereunder.

(p) Neither the Indenture Trustee nor the Securities Administrator shall have any duty to conduct any affirmative investigation as to the occurrence of any condition requiring the repurchase of any Mortgage Loan by the Seller pursuant to this Indenture or the Mortgage Loan Purchase Agreement, as applicable, or the eligibility of any Mortgage Loan for purposes of this Indenture.

(q) The Indenture Trustee shall not be deemed to have notice or actual knowledge of any Default or Event of Default unless actually known to a Responsible Officer of the Indenture Trustee or written notice thereof (making reference to this Indenture or the Notes) is received by the Indenture Trustee at the Corporate Trust Office.

Section 6.03 Individual Rights of Indenture Trustee. The Indenture Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuing Entity or its Affiliates with the same rights it would have if it were not Indenture Trustee, subject to the requirements of the Trust Indenture Act. Any note registrar, co-registrar or co-paying agent may do the same with like rights. However, the Indenture Trustee must comply with Section 6.12 hereof.

Section 6.04 [Reserved].

Section 6.05 Indenture Trustee’s and Securities Administrator’s Disclaimer. Neither the Indenture Trustee nor the Securities Administrator shall be responsible for and makes no representation as to the validity or adequacy of this Indenture, the Notes or any other Basic Document, it shall not be accountable for the Issuing Entity’s use of the proceeds from the Notes, and it shall not be responsible for any statement of the Issuing Entity in the Indenture or in any document issued in connection with the sale of the Notes or in the Notes other than the Securities Administrator’s certificate of authentication.

Section 6.06 Notice of Event of Default. Subject to Section 5.01, the Indenture Trustee shall promptly mail to each Noteholder notice of the Event of Default after it is known to a Responsible Officer of the Indenture Trustee, unless such Event of Default shall have been waived or cured. Except in the case of an Event of Default in payment of principal of or interest on any Note, the Indenture Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the best interests of Noteholders.

Section 6.07 Reports to Holders and Tax Administration.

The Securities Administrator shall deliver to each Noteholder such information as may be required by the Internal Revenue Service or by federal or state law or rules or regulations to enable such holder to prepare its federal and state income tax returns.

The Securities Administrator shall prepare and file (or cause to be prepared and filed), on behalf of the Owner Trustee, all tax returns (if any) and information reports and tax elections and such annual or other reports of the Issuing Entity as are necessary for preparation of tax returns and information reports, each as provided in Section 5.03 of the Trust Agreement, including without limitation Form 1099. All tax returns and information reports shall be signed by the Owner Trustee, or to the extent permitted by law, the Securities Administrator, as provided in Section 5.03 of the Trust Agreement.

Section 6.08 Compensation. An annual fee shall be paid to the Indenture Trustee by the Master Servicer pursuant to a separate agreement between the Indenture Trustee and the Master Servicer. The fee of the Securities Administrator will also be paid by the Master Servicer. In addition, the Indenture Trustee and the Securities Administrator will each be entitled to recover from the Payment Account pursuant to Section 4.03 of the Sale and Servicing Agreement all reasonable out-of-pocket expenses, disbursements and advances and the expenses of the Indenture Trustee and the Securities Administrator, respectively, in connection with any breach of this Indenture or any claim or legal action (including any pending or threatened claim or legal action) or otherwise incurred or made by the Indenture Trustee or the Securities Administrator, respectively, in the administration of the trusts hereunder (including the reasonable compensation, expenses and disbursements of its counsel) except any such expense, disbursement or advance as may arise from its own negligence or intentional misconduct or which is the responsibility of the Noteholders as provided herein. Such compensation and reimbursement obligation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust. Additionally, each of the Indenture Trustee and the Securities Administrator (including in their individual capacity) and any director, officer, employee or agent of the Indenture Trustee or the Securities Administrator shall be indemnified by the Trust and held harmless against any loss, liability or expense (including reasonable attorney’s fees and expenses) incurred in the administration of this Indenture (other than its ordinary out of pocket expenses incurred hereunder) or in connection with any claim or legal action relating to (a) the Basic Documents or (b) the Notes, other than any loss, liability or expense incurred by reason of its own negligence or intentional misconduct, or which is the responsibility of the Noteholders as provided herein.

The Issuing Entity’s payment obligations to the Indenture Trustee and Securities Administrator pursuant to this Section 6.08 shall survive the discharge of this Indenture and the termination or resignation of the Indenture Trustee or Securities Administrator. When the Indenture Trustee or the Securities Administrator incurs expenses after the occurrence of an Event of Default with respect to the Issuing Entity, the expenses are intended to constitute expenses of administration under Title 11 of the United States Code or any other applicable federal or state bankruptcy, insolvency or similar law.

Section 6.09 Replacement of Indenture Trustee and the Securities Administrator. No resignation or removal of the Indenture Trustee or the Securities Administrator and no appointment of a successor Indenture Trustee or a successor Securities Administrator shall become effective until the acceptance of appointment by the successor Indenture Trustee pursuant to this Section 6.09. The Indenture Trustee or the Securities Administrator may resign at any time by so notifying the Issuing Entity. In the event that the Indenture Trustee determines that a conflict of interest exists between the Holders of the Class A Notes and the Holders of any Class of Subordinate Notes, then the Indenture Trustee shall be entitled to resign as the indenture trustee for all Classes of Notes other than the Class A Notes. In such event the Holders of a majority of Note Principal Balances of all of the Subordinate Notes shall designate a separate indenture trustee to represent their interests hereunder. Holders of a majority of Note Principal Balances of each Class of Notes may remove the Indenture Trustee by so notifying the Indenture Trustee and may appoint a successor Indenture Trustee. The Issuing Entity shall remove the Indenture Trustee or the Securities Administrator, as applicable, if:

(i) the Indenture Trustee or the Securities Administrator fails to comply with or qualify pursuant to the provisions of Section 6.12 hereof;

(ii) the Indenture Trustee or the Securities Administrator is adjudged a bankrupt or insolvent;

(iii) a receiver or other public officer takes charge of the Indenture Trustee or the Securities Administrator or its property;

(iv) the Indenture Trustee or the Securities Administrator otherwise becomes incapable of acting; or

(v) the Master Servicer is terminated pursuant to Section 5.01 of the Wells Fargo Servicing Agreement.

If the Indenture Trustee or the Securities Administrator resigns or is removed or if a vacancy exists in the office of the Indenture Trustee or the Securities Administrator for any reason (the Indenture Trustee or the Securities Administrator in such event being referred to herein as the retiring Indenture Trustee or the retiring Securities Administrator ), the Issuing Entity shall promptly appoint a successor Indenture Trustee or successor Securities Administrator.

Each of a successor Indenture Trustee or successor Securities Administrator shall deliver a written acceptance of its appointment to the retiring Indenture Trustee or the retiring Securities Administrator, as applicable, and to the Issuing Entity. Thereupon, the resignation or removal of the retiring Indenture Trustee or the retiring Securities Administrator shall become effective, and the successor Indenture Trustee or successor Securities Administrator shall have all the rights, powers and duties of the Indenture Trustee or the Securities Administrator, as applicable, under this Indenture. The successor Indenture Trustee or successor Securities Administrator shall each mail a notice of its succession to Noteholders. The retiring Indenture Trustee or the retiring Securities Administrator shall promptly transfer all property held by it as Indenture Trustee or Securities Administrator, as applicable, to the successor Indenture Trustee or successor Securities Administrator.

If a successor Indenture Trustee or successor Securities Administrator does not take office within 60 days after the retiring Indenture Trustee or the retiring Securities Administrator, as applicable, resigns or is removed, the retiring Indenture Trustee or the retiring Securities Administrator, the Issuing Entity or the Holders of a majority of Note Principal Balances of the Notes may petition any court of competent jurisdiction for the appointment of a successor Indenture Trustee or successor Securities Administrator.

Notwithstanding the replacement of the Indenture Trustee or the Securities Administrator pursuant to this Section, the Issuing Entity’s obligations under Section 6.07 shall continue for the benefit of the retiring Indenture Trustee or the retiring Securities Administrator.

Section 6.10 Successor Indenture Trustee and Securities Administrator by Merger. If the Indenture Trustee or the Securities Administrator consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business or assets to, another corporation or banking association, the resulting, surviving or transferee corporation, without any further act, shall be the successor Indenture Trustee or successor Securities Administrator, as applicable; provided, that such corporation or banking association shall be otherwise qualified and eligible under Section 6.12 hereof. The Indenture Trustee and the Securities Administrator shall provide the Rating Agencies and the Issuing Entity with prior written notice, and the Noteholders with prompt written notice, of any such transaction.

If at the time such successor or successors by merger, conversion or consolidation to the Securities Administrator shall succeed to the trusts created by this Indenture and any of the Notes shall have been authenticated but not delivered, any such successor to the Securities Administrator may adopt the certificate of authentication of any predecessor securities administrator and deliver such Notes so authenticated; and if at that time any of the Notes shall not have been authenticated, any successor to the Securities Administrator may authenticate such Notes either in the name of any predecessor hereunder or in the name of the successor to the Securities Administrator.

Section 6.11 Appointment of Co-Indenture Trustee or Separate Indenture Trustee. (a) Notwithstanding any other provisions of this Indenture, at any time, for the purpose of meeting any legal requirement of any jurisdiction in which any part of the Trust Estate may at the time be located, the Indenture Trustee shall have the power and may execute and deliver all instruments to appoint one or more Persons to act as a co-trustee or co-trustees, or separate trustee or separate trustees, of all or any part of the Trust Estate, and to vest in such Person or Persons, in such capacity and for the benefit of the Noteholders, such title to the Trust Estate, or any part hereof, and, subject to the other provisions of this Section, such powers, duties, obligations, rights and trusts as the Indenture Trustee may consider necessary or desirable. No co-trustee or separate trustee hereunder shall be required to meet the terms of eligibility as a successor trustee under Section 6.12 hereof.

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

(i) all rights, powers, duties and obligations conferred or imposed upon the Indenture Trustee shall be conferred or imposed upon and exercised or performed by the Indenture 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 Indenture 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 the Indenture 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 Trust Estate 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 Indenture Trustee;

(ii) no trustee hereunder shall be personally liable by reason of any act or omission of any other trustee hereunder; and

(iii) the Indenture Trustee may at any time accept the resignation of or remove any separate trustee or co-trustee.

(c) Any notice, request or other writing given to the Indenture Trustee shall be deemed to have been given to each of the then separate trustees and co-trustees, as effectively as if given to each of them. Every instrument appointing any separate trustee or co-trustee shall refer to this Indenture and the conditions of this Article VI. 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 Indenture Trustee or separately, as may be provided therein, subject to all the provisions of this Indenture, specifically including every provision of this Indenture relating to the conduct of, affecting the liability of, or affording protection to, the Indenture Trustee. Every such instrument shall be filed with the Indenture Trustee.

(d) Any separate trustee or co-trustee may at any time constitute the Indenture 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 Indenture 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 Indenture Trustee, to the extent permitted by law, without the appointment of a new or successor trustee.

Section 6.12 Eligibility; Disqualification. The Indenture Trustee shall at all times be an entity that meets the requirements of Section 3(c)(3) under the Investment Company Act of 1940 applicable to a trustee, and shall have a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition and it or its parent shall have a long-term debt rating of Baa3 or better by Moody’s.

Each of the Indenture Trustee and the Securities Administrator hereunder shall at all times be a corporation or an association organized and doing business under the laws of any 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 and subject to supervision or examination by federal or state authority. In case at any time the Indenture Trustee or the Securities Administrator shall cease to be eligible in accordance with the provisions of this Section, the Trustee or the Securities Administrator, as the case may be, shall resign immediately in the manner and with the effect specified in Section 6.09 hereof.

The Securities Administrator and any successor Securities Administrator (i) may not be an Originator, the Master Servicer, a subservicer, the Depositor or an affiliate of the Depositor unless the Securities Administrator is an institutional trust department, (ii) must be authorized to exercise corporate trust powers under the laws of its jurisdiction of organization, and (iii) must at all times be rated at least “A/F1” by Fitch if Fitch is a rating agency.

The Indenture Trustee shall notify the Rating Agencies of any change of Securities Administrator. Any resignation or removal of the Indenture Trustee or the Securities Administrator and appointment of a successor trustee or trust administrator, as the case may be, pursuant to any of the provisions of this Section shall not become effective until acceptance of appointment by the successor indenture trustee or securities administrator as provided in Section 6.09 hereof. Notwithstanding the foregoing, in the event the

Securities Administrator advises the Indenture Trustee that it is unable to continue to perform its obligations pursuant to the terms of this Indenture prior to the appointment of a successor, the Indenture Trustee shall be obligated to perform such obligations until a new securities administrator is appointed. Such performance shall be without prejudice to any claim by a party hereto or beneficiary hereof resulting from the Securities Administrator’s breach of its obligations hereunder. As compensation therefore, the Indenture Trustee shall be entitled to all fees the Securities Administrator would have been entitled to if it had continued to act hereunder.

Section 9.01 Supplemental Indentures Without Consent of Noteholders. (a) Without the consent of the Holders of any Notes but with prior notice to the Rating Agencies, the Issuing Entity, the Indenture Trustee and the Securities Administrator, when authorized by an Issuer Request, at any time and from time to time, may enter into one or more indentures supplemental hereto, in form satisfactory to the Indenture Trustee and the Securities Administrator, for any of the following purposes:

(i) to correct or amplify the description of any property at any time subject to the lien of this Indenture, or better to assure, convey and confirm unto the Indenture Trustee any property subject or required to be subjected to the lien of this Indenture, or to subject to the lien of this Indenture additional property;

(vii) to make any other provisions with respect to matters or questions arising under this Indenture or in any supplemental indenture; provided, that such action shall not materially and adversely affect the interests of the Holders of the Notes; provided further, that such supplemental indenture will be deemed to not materially and adversely affect the interests of the Holders of the Notes if a Rating Confirmation is received with respect to such supplemental indenture;

(viii) to evidence and provide for the acceptance of the appointment hereunder by a successor trustee with respect to the Notes and to add to or change any of the provisions of this Indenture as shall be necessary to facilitate the administration of the trusts hereunder by more than one trustee, pursuant to the requirements of Article VI hereof;

(ix) to reduce the rating requirements in clause (i) of the definition of Eligible Accounts in Appendix A to this Indenture; or

(x) to modify, eliminate or add to the provisions hereof to such extent as shall be necessary to effect, facilitate or reinforce a REMIC Conversion and all activities related thereto or required therefor;

provided, however, that no such indenture supplements shall be entered into unless the Indenture Trustee and the Securities Administrator shall have received (A) an Opinion of Counsel not at the expense of the Indenture Trustee or the Securities Administrator as to the enforceability of any such indenture supplement and to the effect that (i) such indenture supplement is permitted hereunder and such indenture supplement will not materially and adversely affect the Holders of the Notes (other than in the case of clause (viii) above) and (ii) entering into such indenture supplement will not result in a “significant modification” of the Class I-A-1, Class I-A-2, Class II-A-1, Class II-A-2, Class III-A-1, Class III-A-2, Class IV-A-1 and Class IV-A-2 Notes and any other Classes of Notes with respect to which a “will be debt” opinion has been rendered by nationally recognized tax counsel and furnished to the Securities Administrator under Treasury Regulation Section 1.1001-3 (other than in the case of clause (x) above) or adversely affect the indebtedness status of such Notes or (B) the Depositor obtains a letter from each Rating Agency stating that such supplemental indenture would not result in the downgrading or withdrawal of the respective ratings then assigned to the Notes.

The Indenture Trustee and the Securities Administrator are hereby authorized to join in the execution of any such supplemental indenture and to make any further appropriate agreements and stipulations that may be therein contained.

(b) The Issuing Entity, the Securities Administrator and the Indenture Trustee, when authorized by an Issuer Request, in the case of the Securities Administrator and the Indenture Trustee may, also without the consent of any of the Holders of the Notes and prior notice to the Rating Agencies, enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions to, or changing in any manner or eliminating any of the provisions of, this Indenture or of modifying in any manner the rights of the Holders of the Notes under this Indenture; provided, however, that such action as evidenced by an Opinion of Counsel addressed to the Indenture Trustee, the Securities Administrator and the Owner Trustee, (i) is permitted by this Indenture, (ii) shall not adversely affect in any material respect the interests of any Noteholder (in lieu of this opinion, the Depositor may obtain a letter from each Rating Agency stating that such supplemental indenture would not result in the downgrading or withdrawal of the respective ratings then assigned to the Notes) and (iii) shall not cause the Issuing Entity to be subject to an entity level tax for federal income tax purposes.

Section 9.02 Supplemental Indentures With Consent of Noteholders. The Issuing Entity, the Securities Administrator and the Indenture Trustee, when authorized by an Issuer Request in the case of the Securities Administrator and the Indenture Trustee, also may, with prior notice to the Rating Agencies and, with the consent Holders of not less than a majority of the Note Principal Balance of each Class of Notes affected thereby, by Act (as defined in Section 10.03 hereof) of such Holders delivered to the Issuing Entity, the Securities Administrator and the Indenture Trustee, enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions to, or changing in any manner or eliminating any of the provisions of, this Indenture or of modifying in any manner the rights of the Holders of the Notes under this Indenture; provided, however, that no such supplemental indenture shall, without the consent of the Holder of each Note affected thereby:

(i) change the date of payment of any installment of principal of or interest on any Note, or reduce the principal amount thereof or the interest rate thereon, change the provisions of this Indenture relating to the application of collections on, or the proceeds of the sale of, the Trust Estate and to payment of principal of or interest on the Notes, or change any place of payment where, or the coin or currency in which, any Note or the interest thereon is payable, or impair the right to institute suit for the enforcement of the provisions of this Indenture requiring the application of funds available therefor, as provided in Article V, to the payment of any such amount due on the Notes on or after the respective due dates thereof;

(ii) reduce the percentage of the Note Principal Balances of the Notes, or any Class of Notes, the consent of the Holders of which is required for any such supplemental indenture, or the consent of the Holders of which is required for any waiver of compliance with certain provisions of this Indenture or certain defaults hereunder and their consequences provided for in this Indenture;

(iii) modify or alter the provisions of the proviso to the definition of the term “Outstanding” or modify or alter the exception in the definition of the term “Holder”;

(vi) modify any of the provisions of this Indenture in such manner as to affect the calculation of the amount of any payment of interest or principal due on any Note on any Payment Date (including the calculation of any of the individual components of such calculation); or

(vii) permit the creation of any lien ranking prior to or on a parity with the lien of this Indenture with respect to any part of the Trust Estate or, except as otherwise permitted or contemplated herein, terminate the lien of this Indenture on any property at any time subject hereto or deprive the Holder of any Note of the security provided by the lien of this Indenture;

and provided, further, that such action shall not, as evidenced by an Opinion of Counsel addressed to the Indenture Trustee, the Securities Administrator and the Owner Trustee, cause the Issuing Entity to be subject to an entity level tax for federal income tax purposes.

Any such action shall not adversely affect in any material respect the interest of any Holder (other than a Holder who shall consent to such supplemental indenture) as evidenced by an Opinion of Counsel (provided by the Person requesting such supplemental indenture) delivered to the Indenture Trustee and the Securities Administrator.

It shall not be necessary for any Act of Noteholders under this Section 9.02 to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such Act shall approve the substance thereof.

Promptly after the execution by the Issuing Entity, the Securities Administrator and the Indenture Trustee of any supplemental indenture pursuant to this Section 9.02, the Securities Administrator shall mail to the Holders of the Notes to which such amendment or supplemental indenture relates a notice setting forth in general terms the substance of such supplemental indenture. Any failure of the Securities Administrator to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such supplemental indenture.

Section 9.03 Execution of Supplemental Indentures. In executing, or permitting the additional trusts created by, any supplemental indenture permitted by this Article IX or the modification thereby of the trusts created by this Indenture, the Indenture Trustee and the Securities Administrator shall be entitled to receive, and subject to Sections 6.01 and 6.02 hereof, shall be fully protected in relying upon, an Opinion of Counsel not at the expense of the Indenture Trustee or the Securities Administrator stating that the execution of such supplemental indenture is authorized or permitted by this Indenture. The Indenture Trustee and the Securities Administrator each may, but shall not be obligated to, enter into any such supplemental indenture that affects the Indenture Trustee’s or the Securities Administrator’s own rights, duties, liabilities or immunities under this Indenture or otherwise.

Section 9.04 Effect of Supplemental Indenture. Upon the execution of any supplemental indenture pursuant to the provisions hereof, this Indenture shall be and shall be deemed to be modified and amended in accordance therewith with respect to the Notes affected thereby, and the respective rights, limitations of rights, obligations, duties, liabilities and immunities under this Indenture of the Indenture Trustee, the Securities Administrator, the Issuing Entity and the Holders of the Notes shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments, and all the terms and conditions of any such supplemental indenture shall be and be deemed to be part of the terms and conditions of this Indenture for any and all purposes.

Section 9.05 Conformity with Trust Indenture Act. Every amendment of this Indenture and every supplemental indenture executed pursuant to this Article IX shall conform to the requirements of the Trust Indenture Act as then in effect so long as this Indenture shall then be qualified under the Trust Indenture Act.

MISCELLANEOUS

Section 10.01 Compliance Certificates and Opinions, etc. (a) Upon any application or request by the Issuing Entity to the Indenture Trustee or the Securities Administrator to take any action under any provision of this Indenture, the Issuing Entity shall furnish to the Indenture Trustee and the Securities Administrator (i) an Officer’s Certificate stating that all conditions precedent, if any, provided for in this Indenture relating to the proposed action have been complied with and (ii) an Opinion of Counsel stating that in the opinion of such counsel all such conditions precedent, if any, have been complied with, except that, in the case of any such application or request as to which the furnishing of such documents is specifically required by any provision of this Indenture, no additional certificate or opinion need be furnished.

Every certificate or opinion with respect to compliance with a condition or covenant provided for in this Indenture shall include:

(1) a statement that each signatory of such certificate or opinion has read or has caused to be read such covenant or condition and the definitions herein relating thereto;

(2) a brief statement as to the nature and scope of the examination or investigation upon which the statements or opinions contained in such certificate or opinion are based;

(3) a statement that, in the opinion of each such signatory, such signatory has made such examination or investigation as is necessary to enable such signatory to express an informed opinion as to whether or not such covenant or condition has been complied with;

(4) a statement as to whether, in the opinion of each such signatory, such condition or covenant has been complied with; and

(5) if the signatory of such certificate or opinion is required to be Independent, the statement required by the definition of the term “Independent”.

(b) (i) Prior to the deposit of any Collateral or other property or securities with the Indenture Trustee that is to be made the basis for the release of any property or securities subject to the lien of this Indenture, the Issuing Entity shall, in addition to any obligation imposed in Section 10.01 (a) or elsewhere in this Indenture, furnish to the Indenture Trustee an Officer’s Certificate certifying or stating the opinion of each person signing such certificate as to the fair value (within 90 days prior to such deposit) to the Issuing Entity of the Collateral or other property or securities to be so deposited and a report from a nationally recognized accounting firm verifying such value.

(ii) Whenever the Issuing Entity is required to furnish to the Indenture Trustee an Officer’s Certificate certifying or stating the opinion of any signer thereof as to the matters described in clause (i) above, the Issuing Entity shall also deliver to the Indenture Trustee an Independent Certificate from a nationally recognized accounting firm as to the same matters, if the fair

(iii) Whenever any property or securities are to be released from the lien of this Indenture, the Issuing Entity shall also furnish to the Indenture Trustee an Officer’s Certificate certifying or stating the opinion of each person signing such certificate as to the fair value (within 90 days prior to such release) of the property or securities proposed to be released and stating that in the opinion of such person the proposed release will not impair the security under this Indenture in contravention of the provisions hereof.

(iv) Whenever the Issuing Entity is required to furnish to the Indenture Trustee an Officer’s Certificate certifying or stating the opinion of any signer thereof as to the matters described in clause (iii) above, the Issuing Entity shall also furnish to the Indenture Trustee an Independent Certificate as to the same matters if the fair value of the property or securities and of all other property or securities released from the lien of this Indenture since the commencement of the then-current calendar year, as set forth in the certificates required by clause (iii) above and this clause (iv), equals 10% or more of the Note Principal Balances of the Notes, but such certificate need not be furnished in the case of any release of property or securities if the fair value thereof as set forth in the related Officer’s Certificate is less than $25,000 or less than one percent of the then outstanding Note Principal Balances of the Notes.

Section 10.02 Form of Documents Delivered to Indenture Trustee or the Securities Administrator. In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion with respect to some matters and one or more other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents.

Any certificate or opinion of an Authorized Officer of the Issuing Entity may be based, insofar as it relates to legal matters, upon a certificate or opinion of, or representations by, counsel, unless such officer knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to the matters upon which his certificate or opinion is based are erroneous. Any such certificate of an Authorized Officer or Opinion of Counsel may be based, insofar as it relates to factual matters, upon a certificate or opinion of, or representations by, an officer or officers of the Seller or the Issuing Entity, stating that the information with respect to such factual matters is in the possession of the Seller or the Issuing Entity, unless such counsel knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to such matters are erroneous.

Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Indenture, they may, but need not, be consolidated and form one instrument.

Whenever in this Indenture, in connection with any application or certificate or report to the Indenture Trustee, it is provided that the Issuing Entity shall deliver any document as a condition of the granting of such application, or as evidence of the Issuing Entity’s compliance with any term hereof, it is intended that the truth and accuracy, at the time of the granting of such application or at the effective date of such certificate or report (as the case may be), of the facts and opinions stated in such document shall in such case be conditions precedent to the right of the Issuing Entity to have such application granted or to the sufficiency of such certificate or report. The foregoing shall not, however, be construed to affect the Indenture Trustee’s right to rely upon the truth and accuracy of any statement or opinion contained in any such document as provided in Article VI.

Section 10.03 Acts of Noteholders. (a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Noteholders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Noteholders in person or by agents duly appointed in writing; and except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Indenture Trustee, and, where it is hereby expressly required, to the Issuing Entity. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Noteholders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and (subject to Section 6.01 hereof) conclusive in favor of the Indenture Trustee and the Issuing Entity, if made in the manner provided in this Section 10.03 hereof.

(b) The fact and date of the execution by any person of any such instrument or writing may be proved in any manner that the Indenture Trustee deems sufficient.

(d) Any request, demand, authorization, direction, notice, consent, waiver or other action by the Holder of any Notes shall bind the Holder of every Note issued upon the registration thereof or in exchange therefor or in lieu thereof, in respect of anything done, omitted or suffered to be done by the Indenture Trustee, the Securities Administrator or the Issuing Entity in reliance thereon, whether or not notation of such action is made upon such Note.

Section 10.04 Notices etc., to Indenture Trustee Issuing Entity, Securities Administrator and Rating Agencies. Any request, demand, authorization, direction, notice, consent, waiver or Act of Noteholders or other documents provided or permitted by this Indenture shall be in writing and if such request, demand, authorization, direction, notice, consent, waiver or act of Noteholders is to be made upon, given or furnished to or filed with:

(i) the Indenture Trustee by any Noteholder, by the Securities Administrator or by the Issuing Entity shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing to or with the Indenture Trustee at the Corporate Trust Office. The Indenture Trustee shall promptly transmit any notice received by it from the Noteholders to the Issuing Entity;

(ii) the Securities Administrator by any Noteholder, by the Indenture Trustee or by the Issuing Entity shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing to or with the Securities Administrator at Wells Fargo Bank, N.A., P.O. Box 98, Columbia Maryland 21046 (or, in the case of overnight deliveries, 9062 Old Annapolis Road, Columbia, Maryland 21045), Attn: Bear Stearns ARM Trust 2007-2, or such other address as may hereafter be furnished to the other parties hereto in writing. The Securities Administrator shall promptly transmit any notice received by it from the Noteholders to the Issuing Entity; or

(iii) the Issuing Entity by the Indenture Trustee, the Securities Administrator or by any Noteholder shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing and mailed first-class, postage prepaid to the Issuing Entity addressed to: Bear Stearns ARM 2007-2, in care of Wilmington Trust Company, Rodney Square North 1100 North Market Street, Wilmington, Delaware ###-###-####; Attention: Corporate Trust Services, or at any other address previously furnished in writing to the Indenture Trustee by the Issuing Entity. The Issuing Entity shall promptly transmit any notice received by it from the Noteholders to the Indenture Trustee.

Notices required to be given to the Rating Agencies by the Issuing Entity, the Indenture Trustee, the Securities Administrator or the Owner Trustee shall be in writing, mailed first-class postage pre-paid: in the case of Moody’s, to Moody’s, at the following address: Moody’s Investors Service, Inc., 99 Church Street, New York, New York 10007; in the case of Fitch, One State Street Plaza - 32nd Floor, New York, New York 10004, in the case of Standard & Poor’s, 55 Water Street, 41st Floor, New York, New York 10041; or as to each of the foregoing, at such other address as shall be designated by written notice to the other parties.

Section 10.05 Notices to Noteholders; Waiver. Where this Indenture provides for notice to Noteholders of any event, such notice shall be sufficiently given (unless otherwise herein expressly provided) if made, given, furnished or filed in writing and mailed, first-class, postage prepaid to each Noteholder affected by such event, at such Person’s address as it appears on the Note Register, not later than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice. In any case where notice to Noteholders is given by mail, neither the failure to mail such notice nor any defect in any notice so mailed to any particular Noteholder shall affect the sufficiency of such notice with respect to other Noteholders, and any notice that is mailed in the manner herein provided shall conclusively be presumed to have been duly given regardless of whether such notice is in fact actually received.

Where this Indenture provides for notice in any manner, such notice may be waived in writing by any Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Noteholders shall be filed with the Indenture Trustee but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such a waiver.

In case, by reason of the suspension of regular mail service as a result of a strike, work stoppage or similar activity, it shall be impractical to mail notice of any event to Noteholders when such notice is required to be given pursuant to any provision of this Indenture, then any manner of giving such notice as shall be satisfactory to the Indenture Trustee shall be deemed to be a sufficient giving of such notice.

Where this Indenture provides for notice to the Rating Agencies, failure to give such notice shall not affect any other rights or obligations created hereunder, and shall not under any circumstance constitute an Event of Default.

Section 10.06 Conflict with Trust Indenture Act. If any provision hereof limits, qualifies or conflicts with another provision hereof that is required to be included in this Indenture by any of the provisions of the Trust Indenture Act, such required provision shall control.

The provisions of TIA §§ 310 through 317 that impose duties on any Person (including the provisions automatically deemed included herein unless expressly excluded by this Indenture) are a part of and govern this Indenture, whether or not physically contained herein.

Section 10.07 Effect of Headings. The Article and Section headings herein are for convenience only and shall not affect the construction hereof.

Section 10.08 Successors and Assigns. All covenants and agreements in this Indenture and the Notes by the Issuing Entity shall bind its successors and assigns, whether so expressed or not. All agreements of the Indenture Trustee in this Indenture shall bind its successors, co-trustees and agents.

Section 10.09 Separability. In case any provision in this Indenture or in the Notes shall be invalid, illegal or unenforceable, the validity, legality, and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

Section 10.10 Legal Holidays. In any case where the date on which any payment is due shall not be a Business Day, then (notwithstanding any other provision of the Notes or this Indenture) payment need not be made on such date, but may be made on the next succeeding Business Day with the same force and effect as if made on the date on which nominally due, and no interest shall accrue for the period from and after any such nominal date.

Section 10.11 GOVERNING LAW. THIS INDENTURE SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REFERENCE TO ITS CONFLICT OF LAW PROVISIONS (OTHER THAN SECTIONS 5-1401 AND 5-1402 OF THE NEW YORK GENERAL OBLIGATIONS LAWS, WHICH SHALL APPLY HERETO), AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

Section 10.12 Counterparts. This Indenture may be executed in any number of counterparts, each of which when so executed shall be deemed to be an original, but all such counterparts shall together constitute but one and the same instrument.

Section 10.13 Recording of Indenture. If this Indenture is subject to recording in any appropriate public recording offices, such recording is to be effected by the Issuing Entity and at its expense accompanied by an Opinion of Counsel at its expense (which may be counsel to the Indenture Trustee or any other counsel reasonably acceptable to the Indenture Trustee) to the effect that such recording is necessary either for the protection of the Noteholders or any other Person secured hereunder or for the enforcement of any right or remedy granted to the Indenture Trustee under this Indenture.

Section 10.14 Issuing Entity Obligation. No recourse may be taken, directly or indirectly, with respect to the obligations of the Issuing Entity, the Owner Trustee or the Securities Administrator on the Notes or under this Indenture or any certificate or other writing delivered in connection herewith or therewith, against (i) the Indenture Trustee or the Owner Trustee in its individual capacity, (ii) any owner of a beneficial interest in the Issuing Entity or (iii) any partner, owner, beneficiary, agent, officer, director, employee or agent of the Securities Administrator, the Owner Trustee in its individual capacity, any holder of a beneficial interest in the Issuing Entity, the Securities Administrator, the Owner Trustee or the Indenture Trustee or of any successor or assign of the Indenture Trustee or the Owner Trustee in its individual capacity, except as any such Person may have expressly agreed (it being understood that the Indenture Trustee and the Owner Trustee have no such obligations in their individual capacity) and except that any such partner, owner or beneficiary shall be fully liable, to the extent provided by applicable law, for any unpaid consideration for stock, unpaid capital contribution or failure to pay any installment or call owing to such entity. For all purposes of this Indenture, in the performance of any duties or obligations of the Issuing Entity hereunder, the Owner Trustee shall be subject to, and entitled to the benefits of, the terms and provisions of Article VI, VII and VIII of the Trust Agreement.

Section 10.15 No Petition. The Indenture Trustee and the Securities Administrator, by entering into this Indenture, each Noteholder, by accepting a Note and each Certificateholder, by accepting a Certificate, hereby covenant and agree that they will not at any time prior to one year from the date of termination hereof, institute against the Depositor or the Issuing Entity, or join in any institution against the Depositor or the Issuing Entity of, any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings, or other proceedings under any United States federal or state bankruptcy or similar law in connection with any obligations relating to the Notes, this Indenture or any of the Basic Documents; provided however, that nothing herein shall prohibit the Indenture Trustee from filing proofs of claim in any proceeding.

Section 10.16 Inspection. The Issuing Entity agrees that, at its expense, on reasonable prior notice, it shall permit any representative of the Indenture Trustee or the Securities Administrator, during the Issuing Entity’s normal business hours, to examine all the books of account, records, reports and other papers of the Issuing Entity, to make copies and extracts therefrom, to cause such books to be audited by Independent certified public accountants, and to discuss the Issuing Entity’s affairs, finances and accounts with the Issuing Entity’s officers, employees, and Independent certified public accountants, all at such reasonable times and as often as may be reasonably requested. The Indenture Trustee shall cause its representatives to hold in confidence all such information except to the extent disclosure may be required by law (and all reasonable applications for confidential treatment are unavailing) and except to the extent that the Indenture Trustee or the Securities Administrator may reasonably determine that such disclosure is consistent with its obligations hereunder.

ARTICLE XI

TMP TRIGGER EVENT AND REMIC CONVERSION

Section 11.01 Events to Occur Upon TMP Trigger Event and Prior to REMIC Conversion. (a) Upon the receipt by the Owner Trustee, the Depositor, the Securities Administrator and the Indenture Trustee of a certification substantially in the form of Exhibit F hereto in connection with a proposed transfer of any Privately Offered Notes or Certificates certifying that such transfer will cause a TMP Trigger Event, the following actions shall be promptly taken by the parties identified below in preparation for a REMIC Conversion:

(i) the Issuing Entity shall direct the Master Servicer (A) to cause the related Servicer, pursuant to the Sale and Servicing Agreement and the related Servicing Agreement, to purchase from the Issuing Entity (or with respect to the Mortgage Loans serviced by Wells Fargo but not originated by the Wells Fargo, to purchase on behalf of the Depositor, if so requested by the Depositor), or on behalf of the Issuing Entity to sell to a third party, any REO Property and other Non-REMIC-Eligible Assets at their then fair market values, and remit the proceeds used for such purchase or collected from such sale to the Master Servicer, and (B) to remit such proceeds received from the related Servicer to the Securities Administrator for deposit in the Payment Account;

(iii) the Issuing Entity shall determine the extent to which, if any, that the purchase price of the REO Properties and Non-REMIC-Eligible Assets liquidated pursuant to clause (i) above would result in the allocation of a Realized Loss to any Class of Notes, and shall require the proposed transferor or proposed transferee of the Privately Offered Notes or Certificates causing the TMP Trigger Event to, and such proposed transferor or proposed transferee hereby agrees to, contribute the amount of any such Realized Loss to the Issuing Entity;

(iv) the Issuing Entity shall require the proposed transferor of the Privately Offered Notes causing the TMP Trigger Event to, and such proposed transferor or proposed transferee hereby agrees to, make provisions for payment satisfactory to the Owner Trustee, the Securities Administrator, the Seller and the Indenture Trustee and any other relevant party for any initial or ongoing administrative expenses (including the reasonable fees and expenses of their respective counsel and other professional advisors) associated with the REMIC Conversion and any REMIC created thereby and for any taxes possibly payable as a result of the classification of the Issuing Entity for federal income tax purposes as a “taxable mortgage pool”;
