ARTICLE IV

The Notes; Satisfaction and Discharge of Indenture

Section 4.01.The Notes. The Notes shall be registered in the name of a nominee designated by the Depository. Beneficial Owners will hold interests in the Notes through the book-entry facilities of the Depository in minimum initial Principal Balances of $1,000 and integral multiples of $1,000 in excess thereof.

The Indenture Trustee may for all purposes (including the making of payments due on the Notes) deal with the Depository as the authorized representative of the Beneficial Owners with respect to the Notes for the purposes of exercising the rights of Holders of Notes hereunder. 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, 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 Indenture Trustee 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 Indenture Trustee, 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 Indenture Trustee with the approval of the Issuing Entity 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 Note Registrar and delivered by the Indenture Trustee to or upon the order of the Issuing Entity.

Section 4.02.Registration of and Limitations on Transfer and Exchange of Notes; Appointment of Certificate Registrar. The Issuing Entity shall cause to be kept at its Corporate Trust Office a Note Register in which, subject to such reasonable regulations as it may prescribe, the Note Registrar 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, the Indenture Trustee shall execute and the Note Registrar shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes in authorized initial Security Balances evidencing the same aggregate Percentage Interests.

Subject to the foregoing, at the option of the Noteholders, Notes may be exchanged for other Notes of like tenor or, in each case in authorized initial Principal Balances evidencing the same aggregate Percentage Interests upon surrender of the Notes to be exchanged at the Corporate Trust Office of the Note Registrar. Whenever any Notes are so surrendered for exchange, the Indenture Trustee shall execute and the Note Registrar shall authenticate and deliver the Notes which the Noteholder making the exchange is entitled to receive. Each Note presented or sur rendered for registration of transfer or exchange shall (if so required by the Note Registrar) be duly endorsed by, or be accompanied by a written instrument of transfer in form reasonably satisfactory to the Note Registrar 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.

No service charge shall be made for any registration of transfer or exchange of Notes, but the Note Registrar 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.

All Notes surrendered for registration of transfer and exchange shall be cancelled by the Note Registrar and delivered to the Indenture Trustee for subsequent destruction without liability on the part of either.

The Issuing Entity hereby appoints ______________________________ as Certificate Registrar to keep at its Corporate Trust Office a Certificate Register pursuant to Section 3.09 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 3.05 of the Trust Agreement. __________________________________ hereby accepts such appointment.

Section 4.03.Mutilated, Destroyed, Lost or Stolen Notes. If (i) any mutilated Note is surrendered to the Indenture Trustee, or the Indenture Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Note, and (ii) there is delivered to the Indenture Trustee such security or indemnity as may be required by it to hold the Issuing Entity and the Indenture Trustee harmless, then, in the absence of notice to the Issuing Entity, the Note Registrar or the Indenture Trustee 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 Indenture Trustee shall authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Note, a replacement Note of the same Class; 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 Indenture Trustee 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 or the Indenture Trustee 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 Indenture Trustee) 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 and any agent of the Issuing Entity or the Indenture Trustee 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 neither the Issuing Entity, the Indenture Trustee nor any agent of the Issuing Entity or the Indenture Trustee shall be affected by notice to the contrary.

Section 4.05.Cancellation.

The Issuing Entity may at any time deliver to the Indenture Trustee 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 Indenture Trustee. 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 Indenture Trustee 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 Indenture Trustee.

Section 4.06.Book-Entry Notes. The 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. Such 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. 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 Note Registrar and the Indenture Trustee 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 Owners of 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 Security Balances of the Notes, the Depository shall be deemed to represent such percentage 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 Indenture Trustee.

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 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 Administrator advises the Indenture Trustee in writing that the Depository is no longer willing or able to properly discharge its responsibilities with respect to the Notes and the Administrator is unable to locate a qualified successor, (ii) the Administrator at its option advises the Indenture Trustee in writing that it elects to terminate the book-entry system through the Depository or (iii) after the occurrence of an Event of Default, Owners of Notes representing beneficial interests aggregating at least a majority of the Security Balances of the Notes advise the Depository in writing that the continuation of a book-entry system through the Depository is no longer in the best interests of the Beneficial Owners, then the Depository shall notify all Beneficial Owners and the Indenture Trustee of the occurrence of any such event and of the availability of Definitive Notes to Beneficial Owners requesting the same. Upon surrender to the Indenture Trustee of the typewritten Notes representing the Book-Entry Notes by the Depository, accompanied by registration instructions, the Issuing Entity shall execute and the Indenture Trustee shall authenticate the Definitive Notes in accordance with the instructions of the Depository. None of the Issuing Entity, the Note Registrar or the Indenture Trustee 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 Indenture Trustee shall recognize the Holders of the Definitive Notes as Noteholders.

Section 4.12.Subrogation and Cooperation. (a) The Issuing Entity and the Indenture Trustee acknowledge that (i) to the extent the Credit Enhancer makes payments under the Credit Enhancement Instrument on account of principal of or interest on the Notes, the Credit Enhancer will be fully subrogated to the rights of such Holders to receive such principal and interest from the Issuing Entity, and (ii) the Credit Enhancer shall be paid such principal and interest but only from the sources and in the manner provided herein and in the Insurance Agreement for the payment of such principal and interest.

Pending the preparation of any Definitive Notes, the Issuing Entity may execute and upon its written direction, the Indenture Trustee 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 office or agency of the Indenture Trustee, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Notes, the Issuing Entity shall execute and the Indenture Trustee shall authenticate and make available for delivery, in exchange therefor, Definitive Notes of authorized denominations and of like tenor 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.

ARTICLE V

Default and Remedies

Section 5.01.Events of Default. “Event of Default,” wherever used herein, shall have the meaning provided in Article I; provided, however, that no Event of Default will occur under clause (i) or clause (ii) of the definition of “Event of Default” if the Issuing Entity fails to make payments of principal of and interest on the Notes so long as the Credit Enhancer makes payments sufficient therefore under the Credit Enhancement Instrument.

The Issuing Entity shall deliver to the Indenture Trustee and the Credit Enhancer, within five days after learning of the occurrence of an Event of 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 (iii) of the definition of “Event of Default”, its status and what action the Issuing Entity is taking or proposes to take with respect thereto.

Section 5.02.Acceleration of Maturity; Rescission and Annulment. If an Event of Default should occur and be continuing or if the Master Servicer shall purchase all of the Mortgage Loans pursuant to Section 8.08 of the Servicing Agreement, then and in every such case the Indenture Trustee or the Holders of Notes representing not less than a majority of the Security Balances of all 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 given by Noteholders), and upon any such declaration the unpaid principal amount of such Class of Notes, together with accrued and unpaid interest thereon through the date of acceleration, shall become immediately due and payable. Unless the prior written consent of the Credit Enhancer shall have been obtained by the Indenture Trustee, the Payment Date upon which such accelerated payment is due and payable shall not be a Payment Date under the Credit Enhancement Instrument and the Indenture Trustee shall not be authorized under Section 3.29 to make a draw therefor.

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, the Holders of Notes representing a majority of the Security Balances of all Notes, by written notice to the Issuing Entity and the Indenture Trustee, may 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 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 upon the Notes if the Event of Default giving rise to such acceleration had not occurred; and

(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 Issue shall, upon demand of the Indenture Trustee, pay to it, for the benefit of the Holders of Notes and of the Credit Enhancer, the whole amount then due and payable on the Notes for principal and interest, with interest 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 10.17 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 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 10.17 hereof may, as more particularly provided in Section 5.04, in its discretion, proceed to protect and enforce its rights and the rights of the Noteholders and the Credit Enhancer, by such appropriate Proceedings as the Indenture Trustee shall deem most effective 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, 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 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 Indenture Trustee, 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 except as a result of negligence or bad faith.

(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 Note holder 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.

(g)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, the Indenture Trustee subject to the provisions of Section 10.17 hereof may do one or more of the following (subject to Section 5.05):

(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, and all amounts payable under the Insurance Agreement, 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, the Holders of the Notes and the Credit Enhancer; 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 Principal Balances of the Notes and the Credit Enhancer, which consent will not be unreasonably withheld, (B) the proceeds of such sale or liquidation distributable to Holders are sufficient to discharge in full all amounts then due and unpaid upon the Notes for principal and interest and to reimburse the Credit Enhancer for any amounts drawn under the Credit Enhancement Instrument and any other amounts due the Credit Enhancer under the Insurance Agreement 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 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 Credit Enhancer, which consent will not be unreasonably withheld, and of the Holders of a majority of the aggregate Principal Balances of the Notes. 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 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 fore going, so long as an Event of Servicer Termination has not occurred, any Sale of the Trust Estate shall be made subject to the continued Servicing of the Mortgage Loans by the Master Servicer as provided in the Servicing Agreement.

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

First: to the Indenture Trustee for amounts due under Section 6.07;

Second: to each Class of Noteholders for amounts due and unpaid on the related Class Notes for interest and to each Noteholder of such Class in each case, ratably, without preference or priority of any kind, according to the amounts due and payable on such Class of Notes for interest from amounts available in the Trust Estate for such Noteholders;

Third: to Holders of each Class of Notes for amounts due and unpaid on the related Class of Notes for principal, from amounts available in the Trust Estate for such Noteholders, and to each Noteholder of such Class in each case ratably, without preference or priority of any kind, according to the amounts due and payable on such Class of Notes for principal, until the Security Balances of each Class of Notes is reduced to zero;

Fourth: to the Issuing Entity for amounts required to be distributed to the Certificateholders in respect of interest and principal pursuant to the Trust Agreement;

Fifth: To the payment of all amounts due and owing to the Credit Enhancer under the Insurance Agreement;

Sixth: to the Issuing Entity for amounts due under Article VIII of the Trust Agreement; and

Seventh: to the payment of the remainder, if any to the Issuing Entity or any other person legally entitled thereto.

The Indenture Trustee 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 Indenture Trustee 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, but need not, 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 including payment to the Credit Enhancer, 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. 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 provisions of Section 10.17 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 Security Balances of the Notes have made 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, 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 Security 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.

In the event the Indenture Trustee shall receive conflicting or inconsistent requests and indemnity from two or more groups of Holders of Notes, each representing less than a majority of the Security Balances of the Notes, the Indenture Trustee in its sole discretion may determine what action, if any, shall be taken, 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.

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 Security 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)subject to the express terms of Section 5.04, 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 Security Balances of Notes;

(iii)if the conditions set forth in Section 5.05 have been satisfied and the Indenture Trustee elects to retain the Trust Estate pursuant to such Section, then any direction to the Indenture Trustee by Holders of Notes representing less than 100% of the Security Balances of Notes to sell or liquidate the Trust Estate shall be of no force and effect; and

(iv)the Indenture Trustee may take any other action deemed proper by the Indenture Trustee that is not inconsistent with such direction.

Notwithstanding the rights of Noteholders set forth in this Section, subject to Section 6.01, the Indenture Trustee need not take any action that it determines might involve it in liability or might materially adversely affect the rights of any Noteholders not consenting to such action.

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, the Holders of Notes of not less than a majority of the Security Balances of the 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 or (c) the waiver of which would mate rially and adversely affect the interests of the Credit Enhancer or modify its obligation under the Credit Enhancement Instrument. 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 by such Holder’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 Security 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 is expressly subject to the provisions of Section 5.05 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 and under the Insurance Agreement 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 and the Credit Enhancer 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 and the Credit Enhancer in respect of amounts drawn under the Credit Enhancement Instrument and any other amounts due the Credit Enhancer under the Insurance Agreement, in full payment thereof in accordance with Section 5.02, on the Payment Date next succeeding the date of such Sale, or

(3)the Indenture Trustee determines, in its sole discretion, that the conditions for retention of the Trust Estate set forth in Section 5.05 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), and the Credit Enhancer consents to such Sale, which consent will not be unreasonably withheld and the Holders representing at least 66-2/3% of the Security Balances of the Notes consent to such Sale.

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)Unless the Holders and the Credit Enhancer 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 shall bid an amount at least $1.00 more than the highest other bid.

(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 with the consent of the Credit Enhancer 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 and amounts owing to the Credit Enhancer as a result of such Sale in accordance with Section 5.04(b) 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 transferring its interest in any portion of the Trust Estate in connection with a Sale thereof;

(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; and

(5)no purchaser or transferee at such a Sale shall be bound to ascertain the Indenture Trustee’s authority, inquire into the satisfaction of any conditions precedent or see to the application of any monies.

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 shall be applied in accordance with Section 5.04(b).

Section 5.17.Performance and Enforcement of Certain Obligations. (a) Promptly following a request from the Indenture Trustee to do so and at the Administrator’s expense, the Issuing Entity in its capacity as holder of the Mortgage Loans, shall take all such lawful action as the Indenture Trustee may request to cause the Issuing Entity to compel or secure the performance and observance by the Sponsor and the Master Servicer, as applicable, of each of their obligations to the Issuing Entity under or in connection with the Mortgage Loan Purchase Agreement and the Servicing Agreement, and to exercise any and all rights, remedies, powers and privileges lawfully available to the Issuing Entity under or in connection with the Mortgage Loan Purchase Agreement and the Servicing Agreement to the extent and in the manner directed by the Indenture Trustee, as pledgee of the Mortgage Loans, including the transmission of notices of default on the part of the Sponsor or the Master Servicer thereunder and the institution of legal or administrative actions or proceedings to compel or secure performance by the Sponsor or the Master Servicer of each of their obligations under the Mortgage Loan Purchase Agreement and the Servicing Agreement.

(b)If an Event of Default has occurred and is continuing, the Indenture Trustee, as pledgee of the Mortgage Loans, subject to the rights of the Credit Enhancer under the Servicing Agreement may, and at the direction (which direction shall be in writing or by telephone (confirmed in writing promptly thereafter)) of the Holders of 66-2/3% of the Security Balances of the Notes shall, exercise all rights, remedies, powers, privileges and claims of the Issuing Entity against the Sponsor or the Master Servicer under or in connection with the Mortgage Loan Purchase Agreement and the Servicing Agreement, including the right or power to take any action to compel or secure performance or observance by the Sponsor or the Master Servicer, as the case may be, of each of their obligations to the Issuing Entity thereunder and to give any consent, request, notice, direction, approval, extension or waiver under the Mortgage Loan Purchase Agreement and the Servicing Agreement, as the case may be, and any right of the Issuing Entity to take such action shall not be suspended.

ARTICLE VI

The Indenture Trustee

Section 6.01.Duties of Indenture Trustee.

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

(ii)the Indenture Trustee 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 was negligent in ascertaining the pertinent facts; and

(f)No provision of this Indenture shall require the Indenture Trustee 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 adequate indemnity against such risk or liability is not reasonably assured to it.

Section 6.04.Indenture Trustee’s Disclaimer. The Indenture Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Notes, 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 Indenture Trustee’s certificate of authentication.

Section 6.07.Compensation and Indemnity. The Issuing Entity shall or shall cause the Administrator to pay to the Indenture Trustee on each Payment Date reasonable compensation for its services.

The Indenture Trustee shall notify the Issuing Entity and the Administrator promptly of any claim for which it may seek indemnity. Failure by the Indenture Trustee to so notify the Issuing Entity and the Administrator shall not relieve the Issuing Entity or the Administrator of its obligations hereunder. The Issuing Entity shall or shall cause the Administrator to defend any such claim, and the Indenture Trustee may have separate counsel and the Issuing Entity shall or shall cause the Administrator to pay the fees and expenses of such counsel. Neither the Issuing Entity nor the Administrator need reimburse any expense or indemnify against any loss, liability or expense incurred by the Indenture Trustee through the Indenture Trustee’s own willful misconduct, negligence or bad faith.

The Issuing Entity’s payment obligations to the Indenture Trustee pursuant to this Section 6.07 shall survive the discharge of this Indenture. When the Indenture Trustee incurs expenses after the occurrence of an Event of Default specified in Section 5.01(iv) or (v) 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.

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

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

(iv)the Indenture Trustee otherwise becomes incapable of acting.

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

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

Supplemental Indentures

Section 9.01.Supplemental Indentures Without Consent of Noteholders. (a) Without the consent of the Holders of any Notes but with the consent of the Credit Enhancer and prior notice to the Rating Agencies and the Credit Enhancer, the Issuing Entity and the Indenture Trustee, when authorized by an Issuer Request, at any time and from time to time, may enter into one or more indentures supplemental hereto (which shall conform to the provisions of the Trust Indenture Act as in force at the date of the execution thereof), in form satisfactory to the Indenture Trustee, 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;

(ii)to evidence the succession, in compliance with the applicable provisions hereof, of another person to the Issuing Entity, and the assumption by any such successor of the covenants of the Issuing Entity herein and in the Notes contained;

(vii)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; or

(viii)to modify, eliminate or add to the provisions of this Indenture to such extent as shall be necessary to effect the qualification of this Indenture under the TIA or under any similar federal statute hereafter enacted and to add to this Indenture such other provisions as may be expressly required by the TIA;

provided, however, that no such indenture supplements shall be entered into unless the Indenture Trustee shall have received an Opinion of Counsel that entering into such indenture supplement will not have any material adverse tax consequences to the Noteholders.

The Indenture Trustee is 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 and the Indenture Trustee, when authorized by an Issuer Request, may, also without the consent of any of the Holders of the Notes but with the consent of the Credit Enhancer and prior notice to the Rating Agencies and the Credit Enhancer, 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 shall not, as evidenced by an Opinion of Counsel, (i) adversely affect in any material respect the interests of any Noteholder or (ii) cause the Issuing Entity to be subject to an entity level tax.

Section 9.02.Supplemental Indentures With Consent of Noteholders. The Issuing Entity and the Indenture Trustee, when authorized by an Issuer Request, also may, with prior notice to the Rating Agencies and, with the written consent of the Credit Enhancer and with the consent of the Holders of not less than a majority of the Security Balances of each Class of Notes affected thereby, by Act of such Holders delivered to the Issuing Entity 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 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 Security Balances of the 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”;

(v)modify any provision of this Section 9.02 except to increase any percentage specified herein or to provide that certain additional provisions of this Indenture or the Basic Documents cannot be modified or waived without the consent of the Holder of each Note affected thereby;

(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, cause the Issuing Entity to be subject to an entity level tax.

The Indenture Trustee may in its discretion determine whether or not any Notes would be affected by any supplemental indenture and any such determination shall be conclusive upon the Holders of all Notes, whether theretofore or thereafter authenticated and delivered hereunder. The Indenture Trustee shall not be liable for any such determination made in good faith.

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 and the Indenture Trustee of any supplemental indenture pursuant to this Section 9.02, the Indenture Trustee 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 Indenture Trustee 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 shall be entitled to receive, and subject to Sections 6.01 and 6.02, shall be fully protected in relying upon, an Opinion of Counsel stating that the execution of such supplemental indenture is authorized or permitted by this Indenture. The Indenture Trustee may, but shall not be obligated to, enter into any such supplemental indenture that affects the Indenture Trustee’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 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.

Section 9.06.Reference in Notes to Supplemental Indentures. Notes authenticated and delivered after the execution of any supplemental indenture pursuant to this Article IX may, and if required by the Indenture Trustee shall, bear a notation in form approved by the Indenture Trustee as to any matter provided for in such supplemental indenture. If the Issuing Entity or the Indenture Trustee shall so determine, new Notes so modified as to conform, in the opinion of the Indenture Trustee and the Issuing Entity, to any such supplemental indenture may be prepared and executed by the Issuing Entity and authenticated and delivered by the Indenture Trustee in exchange for Outstanding Notes.

ARTICLE X

Section 10.01.Compliance Certificates and Opinions, Etc. (a) Upon any application or request by the Issuing Entity to the Indenture Trustee to take any action under any provision of this Indenture, the Issuing Entity shall furnish to the Indenture Trustee and to the Credit Enhancer (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;

(5) if the Signer 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 of such deposit) to the Issuing Entity of the Collateral or other property or securities to be so deposited.

(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 as to the same matters, if the fair value to the Issuing Entity of the securities to be so deposited and of all other such securities made the basis of any such withdrawal or release since the commencement of the then-current fiscal year of the Issuing Entity, as set forth in the certificates delivered pursuant to clause (i) above and this clause (ii), is 10% or more of the Security Balances of the Notes, but such a certificate need not be furnished with respect to any securities so deposited, if the fair value thereof to the Issuing Entity as set forth in the related Officer’s Certificate is less than $25,000 or less than one percent of the Security Balances of the Notes.

(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 of 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, other than property as contemplated by clause (v) below 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 Security 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 Security Balances of the Notes.

(v)Notwithstanding any provision of this Indenture, the Issuing Entity may, without compliance with the requirements of the other provisions of this Section 10.01, (A) collect, sell or otherwise dispose of the Mortgage Loans as and to the extent permitted or required by the Basic Documents or (B) make cash payments out of the Payment Account as and to the extent permitted or required by the Basic Documents [, so long as the Issuing Entity shall deliver to the Indenture Trustee every six months, commencing _____________, an Officer’s Certificate of the Issuing Entity stating that all the dispositions of Collateral described in clauses (A) or (B) above that occurred during the preceding six calendar months were in the ordinary course of the Issuing Entity’s business and that the proceeds thereof were applied in accordance with the Basic Documents].

Section 10.02.Form of Documents Delivered to Indenture Trustee. 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 Sponsor, the Issuing Entity or the Administrator, stating that the information with respect to such factual matters is in the possession of the Sponsor, the Issuing Entity or the Administrator, 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) conclusive in favor of the Indenture Trustee and the Issuing Entity, if made in the manner provided in this Section 10.03.

(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.

(c)The ownership of Notes shall be proved by the Note Registrar.

(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 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, Credit Enhancer and Rating Agencies. Any request, demand, authorization, direction, notice, consent, waiver or Act of Note holders 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 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, or

(ii)the Issuing Entity by the Indenture Trustee or by any Noteholder shall be sufficient for every purpose hereunder if in writing and mailed first-class, postage prepaid to the Issuing Entity addressed to: ISAC MBN Trust Series 200_ - ______, in care of [Name of Owner Trustee] _________________, __________, ______________, Attention of _________________________________________ with a copy to the Administrator at ________________ Attention: __________ __________________________, or at any other address previously furnished in writing to the Indenture Trustee by the Issuing Entity or the Administrator. The Issuing Entity shall promptly transmit any notice received by it from the Noteholders to the Indenture Trustee, or

(iii)the Credit Enhancer by the Issuing Entity, the Indenture Trustee or by any Noteholders shall be sufficient for every purpose hereunder to in writing and mailed, first-class postage pre-paid, or personally delivered or telecopied to: [Name of Credit Enhancer], ________________, ________, _______________, Attention: _________________, ___________________________, Telephone ______________. Telecopier ______________. The Credit Enhancer shall promptly transmit any notice received by it from the Issuing Entity, the Indenture Trustee or the Noteholders to the Issuing Entity or Indenture Trustee, as the case may be.

Notices required to be given to the Rating Agencies by the Issuing Entity, the Indenture Trustee or the Owner Trustee shall be in writing, personally delivered or mailed by certified mail, return receipt requested, to (i) in the case of [Moody’s], at the following address: [Moody’s Investors Service, Inc., ABS Monitoring Department, 99 Church Street, New York, New York 10007] and (ii) in the case of [Standard & Poor’s], at the following address: [Standard & Poor’s Ratings Group, 26 Broadway (15th Floor), New York, New York 10004, Attention of Asset Backed Surveillance Department]; 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 in writing and mailed, first-class, postage prepaid to each Noteholder affected by such event, at such Person’s 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.Alternate Payment and Notice Provisions. Notwithstanding any provision of this Indenture or any of the Notes to the contrary, the Issuing Entity may enter into any agreement with any Holder of a Note providing for a method of payment, or notice by the Indenture Trustee or any Administrator to such Holder, that is different from the methods provided for in this Indenture for such payments or notices. The Issuing Entity shall furnish to the Indenture Trustee a copy of each such agreement and the Indenture Trustee shall cause payments to be made and notices to be given in accordance with such agreements.

Section 10.07.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 §§ 10 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 10.08.Effect of Headings. The Article and Section headings herein are for convenience only and shall not affect the construction hereof.

Section 10.09.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 10.10.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 10.11.Benefits of Indenture. The Credit Enhancer and its successors and assigns shall be a third-party beneficiary to the provisions of this Indenture. Nothing in this Indenture or in the Notes, express or implied, shall give to any Person, other than the parties hereto and their successors hereunder, and the Noteholders, and any other party secured hereunder, and any other Person with an ownership interest in any part of the Trust Estate, any benefit or any legal or equitable right, remedy or claim under this Indenture.

Section 10.12.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 10.13.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, AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

Section 10.14.Counterparts. This Indenture may be executed in any number of counterparts, each of which so executed shall be deemed to be an original, but all such counterparts shall together constitute but one and the same instrument.

Section 10.15.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 (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 10.16.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 Indenture Trustee 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 Indenture Trustee or the Owner Trustee in its individual capacity, any holder of a beneficial interest in the Issuing Entity, 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 10.17.No Petition. The Indenture Trustee, by entering into this Indenture, and each Noteholder, by accepting a Note, hereby covenant and agree that they will not at any time 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.

Section 10.18.Inspection. The Issuing Entity agrees that, on reasonable prior notice, it shall permit any representative of the Indenture Trustee, 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 and 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 may reasonably determine that such disclosure is consistent with its obligations hereunder.

Section 10.19.Authority of the Administrator. Each of the parties to this Indenture acknowledges that the Issuing Entity and the Owner Trustee have each appointed the Administrator to act as its agent to perform the duties and obligations of the Issuing Entity hereunder. Unless otherwise instructed by the Issuing Entity or the Owner Trustee, copies of all notices, requests, demands and other documents to be delivered to the Issuing Entity or the Owner Trustee pursuant to the terms hereof shall be delivered to the Administrator.

The Issuing Entity shall not be liable upon the indebtedness evidenced by the Bonds except to the extent of amounts available from the Trust Estate which constitutes security for the payment of the Bonds. The assets included in the Trust Estate will be the sole source of payments on the Class [_]-A-[_] Bonds, and each Holder hereof, by its acceptance of this Bond, agrees that (i) such Bond will be limited in right of payment to amounts available from the Trust Estate as provided in the Indenture and (ii) such Holder shall have no recourse to the Issuing Entity, the Owner Trustee, the Indenture Trustee, Impac Secured Assets Corp., Impac Mortgage Holdings, Inc., the Master Servicer or any of their respective affiliates, or to the assets of any of the foregoing entities, except the assets of the Issuing Entity pledged to secure the Class [_]-A-[_] Bonds pursuant to the Indenture and the rights conveyed to the Issuing Entity under the Indenture.

The failure to pay any Unpaid Interest Shortfall at any time when funds are not available to make such payment as provided in the Indenture shall not constitute an Event of Default under the Indenture.

The Holder of this Bond or Beneficial Owner of any interest herein is deemed to represent that either (1) it is not acquiring the Bond with Plan Assets or (2) (A) the acquisition, holding and transfer of a Bond will not give rise to a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code as a result of the Issuing Entity, the Sponsor, the Depositor, the Underwriters, the Owner Trustee, the Indenture Trustee, the Master Servicer, any Subservicer, any other servicer, any administrator, any provider of credit support, any owner of the Certificates, or any of their Affiliates being a “Party in Interest” (within the meaning of ERISA) or Disqualified Person (within the meaning of the Code) with respect to such Holder or Beneficial Owner that is a Plan and (B) the Bonds are rated investment grade or better and such person believes that the Bonds are properly treated as indebtedness without substantial equity features for purposes of the DOL Regulations, and agrees to so treat the Bonds.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Bond may be registered on the Bond Register of the Issuing Entity. Upon surrender for registration of transfer of, or presentation of a written instrument of transfer for, this Bond at the office or agency designated by the Issuing Entity pursuant to the Indenture, accompanied by proper instruments of assignment in form satisfactory to the Indenture Trustee, one or more new Bonds of any authorized denominations and of a like aggregate initial [Bond Principal Balance][Notional Amount], will be issued to the designated transferee or transferees.

The Indenture also contains provisions permitting the Holders of Bonds representing specified percentages of the aggregate Bond Principal Balance of the Bonds on behalf of the Holders of all the Bonds, to waive any past Default under the Indenture and its consequences. Any such waiver by the Holder, at the time of the giving thereof, of this Bond (or any one or more predecessor Bonds) shall bind the Holder of every Bond issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof, whether or not notation of such consent or waiver is made upon such Bond. The Indenture also permits the Issuing Entity and the Indenture Trustee to amend or waive certain terms and conditions set forth in the Indenture without the consent of the Holders of the Bonds issued thereunder.

Initially, the Bonds will be registered in the name of Cede & Co. as nominee of DTC, acting in its capacity as the Depository for the Bonds.

All payments made by the Issuing Entity with respect to this Bond shall be equal to this Bond’s pro rata share of the aggregate payments on all Class [_]-B Bonds as described above, and shall be applied as between interest and principal as provided in the Indenture.

All principal and interest accrued on the Bonds, if not previously paid, will become finally due and payable at the Final Scheduled Payment Date.

The Group [1][2] Bonds are subject to redemption in whole, but not in part, by the Majority Certificateholder, on or after the earlier of (i) the Payment Date on which the aggregate Stated Principal Balance of the Group [1][2] Loans as of the end of the related Due Period is less than or equal to __% of the sum of the aggregate Stated Principal Balance of the Group [1][2] Loans as of the Cut-off Date, and (ii) the Payment Date occurring in _________ 20__.

The Issuing Entity shall not be liable upon the indebtedness evidenced by the Bonds except to the extent of amounts available from the Trust Estate which constitutes security for the payment of the Bonds. The assets included in the Trust Estate will be the sole source of payments on the Class [_]-B Bonds, and each Holder hereof, by its acceptance of this Bond, agrees that (i) such Bond will be limited in right of payment to amounts available from the Trust Estate as provided in the Indenture and (ii) such Holder shall have no recourse to the Issuing Entity, the Owner Trustee, the Indenture Trustee, Impac Secured Assets Corp., Impac Mortgage Holdings, Inc., the Master Servicer or any of their respective affiliates, or to the assets of any of the foregoing entities, except the assets of the Issuing Entity pledged to secure the Class [_]-B Bonds pursuant to the Indenture and the rights conveyed to the Issuing Entity under the Indenture.

Any payment of principal or interest payable on this Bond which is punctually paid on the applicable Payment Date shall be paid to the Person in whose name such Bond is registered at the close of business on the Record Date for such Payment Date by check mailed to such Person’s address as it appears in the Bond Register on such Record Date, except for the final installment of principal and interest payable with respect to such Bond, which shall be payable as provided below. Notwithstanding the foregoing, upon written request with appropriate instructions by the Holder of this Bond delivered to the Indenture Trustee at least five Business Days prior to the Record Date, any payment of principal or interest, other than the final installment of principal or interest, shall be made by wire transfer to an account in the United States designated by such Holder. All reductions in the principal amount of a Bond (or one or more predecessor Bonds) effected by payments of principal made on any Payment Date shall be binding upon all Holders of this Bond and of any bond issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof, whether or not such payment is noted on such Bond. The final payment of this Bond shall be payable upon presentation and surrender thereof on or after the Payment Date thereof at the Corporate Trust Office or the office or agency of the Issuing Entity maintained by it for such purpose pursuant to Section 3.02 of the Indenture.

Subject to the foregoing provisions, each Bond delivered under the Indenture, upon registration of transfer of or in exchange for or in lieu of any other Bond shall carry the right to unpaid principal and interest that were carried by such other Bond.

If an Event of Default as defined in the Indenture shall occur and be continuing with respect to the Bonds, the Bonds may become or be declared due and payable in the manner and with the effect provided in the Indenture. If any such acceleration of maturity occurs prior to the payment of the entire unpaid Bond Principal Balance of the Bonds, the amount payable to the Holder of this Bond will be equal to the sum of the unpaid Bond Principal Balance of the Bonds, together with accrued and unpaid interest thereon as described in the Indenture. The Indenture provides that, notwithstanding the acceleration of the maturity of the Bonds, under certain circumstances specified therein, all amounts collected as proceeds of the Trust Estate securing the Bonds or otherwise shall continue to be applied to payments of principal of and interest on the Bonds as if they had not been declared due and payable.

The failure to pay any Unpaid Interest Shortfall at any time when funds are not available to make such payment as provided in the Indenture shall not constitute an Event of Default under the Indenture.

The Holder of this Bond or Beneficial Owner of any interest herein is deemed to represent that either (1) it is not acquiring the Bond with Plan Assets or (2) (A) the acquisition, holding and transfer of a Bond will not give rise to a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code as a result of the Issuing Entity, the Sponsor, the Depositor, the Underwriters, the Owner Trustee, the Indenture Trustee, the Master Servicer, any Subservicer, any other servicer, any administrator, any provider of credit support, any owner of the Certificates, or any of their Affiliates being a “Party in Interest” (within the meaning of ERISA) or Disqualified Person (within the meaning of the Code) with respect to such Holder or Beneficial Owner that is a Plan and (B) the Bonds are rated investment grade or better and such person believes that the Bonds are properly treated as indebtedness without substantial equity features for purposes of the DOL Regulations, and agrees to so treat the Bonds. Alternatively, regardless of the rating of the Bonds, such person may provide the Indenture Trustee and the Owner Trustee with an opinion of counsel, which opinion of counsel will not be at the expense of the Issuing Entity, the Sponsor, any Underwriter, the Owner Trustee, the Indenture Trustee, the Master Servicer or any successor servicer which opines that the acquisition, holding and transfer of such Bond 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 Sponsor, the Depositor, any Underwriter, the Owner Trustee, the Indenture Trustee, the Master Servicer or any successor servicer to any obligation in addition to those undertaken in the Indenture.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Bond may be registered on the Bond Register of the Issuing Entity. Upon surrender for registration of transfer of, or presentation of a written instrument of transfer for, this Bond at the office or agency designated by the Issuing Entity pursuant to the Indenture, accompanied by proper instruments of assignment in form satisfactory to the Indenture Trustee, one or more new Bonds of any authorized denominations and of a like aggregate initial Bond Principal Balance, will be issued to the designated transferee or transferees.

Prior to the due presentment for registration of transfer of this Bond, the Issuing Entity, the Indenture Trustee and any agent of the Issuing Entity or the Indenture Trustee may treat the Person in whose name this Bond is registered as the owner of such Bond (i) on the applicable Record Date for the purpose of making payments and interest of such Bond, and (ii) on any other date for all other purposes whatsoever, as the owner hereof, whether or not this Bond be overdue, and neither the Issuing Entity, the Indenture Trustee nor any such agent of the Issuing Entity or the Indenture Trustee shall be affected by notice to the contrary.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Issuing Entity and the rights of the Holders of the Bonds under the Indenture at any time by the Issuing Entity with the consent of the Holders of a majority of all Bonds at the time outstanding. The Indenture also contains provisions permitting the Holders of Bonds representing specified percentages of the aggregate Bond Principal Balance of the Bonds on behalf of the Holders of all the Bonds, to waive any past Default under the Indenture and its consequences. Any such waiver by the Holder, at the time of the giving thereof, of this Bond (or any one or more predecessor Bonds) shall bind the Holder of every Bond issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof, whether or not notation of such consent or waiver is made upon such Bond. The Indenture also permits the Issuing Entity and the Indenture Trustee to amend or waive certain terms and conditions set forth in the Indenture without the consent of the Holders of the Bonds issued thereunder.

Initially, the Bonds will be registered in the name of Cede & Co. as nominee of DTC, acting in its capacity as the Depository for the Bonds. The Bonds will be delivered by the clearing agency in denominations as provided in the Indenture and subject to certain limitations therein set forth. The Bonds are exchangeable for a like aggregate initial Bond Principal Balance of Bonds of different authorized denominations, as requested by the Holder surrendering same.

Unless the Certificate of Authentication hereon has been executed by the Indenture Trustee by manual signature, this Bond shall not be entitled to any benefit under the Indenture, or be valid or obligatory for any purpose.

AS PROVIDED IN THE INDENTURE, THIS BOND AND THE INDENTURE CREATING THIS BOND SHALL BE CONSTRUED IN ACCORDANCE WITH, AND GOVERNED BY, THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED THEREIN.
