Section 2.03 Acceptance of Mortgage Loans by Indenture Trustee. (a) The Indenture Trustee acknowledges receipt of, subject to the exceptions the related Custodian notes pursuant to the procedures described below, the documents (or certified copies thereof) referred to in Section 2.1(b) of the Mortgage Loan Purchase Agreement with respect to the Mortgage Loans, and the Custodians hold and will continue to hold those documents and any amendments, replacements or supplements thereto and all other assets of the Trust Estate as Indenture Trustee (or on behalf of the Indenture Trustee, as applicable) in trust for the use and benefit of all present and future Holders of the Bonds. No later than 45 days after the Closing Date with respect to the Mortgage Loans, (or, with respect to any Eligible Substitute Mortgage Loan, within 5 days after the receipt by the related Custodian thereof and, with respect to any documents received beyond 45 days after the Closing Date, promptly thereafter), the related Custodian agrees, for the benefit of the Bondholders, to review each Mortgage File delivered to it and to execute and deliver, or cause to be executed and delivered, to the Seller and the Master Servicer an Initial Certification in the form annexed hereto as Exhibit G. In conducting such review, the related Custodian will ascertain whether all required documents described in Section 2.1(b) of the Mortgage Loan Purchase Agreement, with respect to the Mortgage Loans, have been executed and received and whether those documents relate, determined on the basis of the Mortgagor name, original principal balance and loan number, to the Mortgage Loans it has received, as identified in Exhibit B to this Indenture, as supplemented (provided, however, that with respect to those documents described in subclause (b)(vii) of such section, the Indenture Trustee’s obligations shall extend only to documents actually delivered pursuant to such subclause). In performing any such review, the related Custodian may conclusively rely on the purported due execution and genuineness of any such document and on the purported genuineness of any signature thereon. If a Custodian finds any document constituting part of the Mortgage File not to have been executed or received, or to be unrelated to the Mortgage Loans identified in Exhibit B to this Indenture or to appear to be defective on its face, the related Custodian shall promptly notify the Seller of such finding and the Seller’s obligation to cure such defect or repurchase or substitute for the related Mortgage Loan. To the extent that a Custodian has not received a Mortgage File with

respect to any of the Mortgage Loans by the Closing Date, the Indenture Trustee shall not require the deposit of cash into the Payment Account or any other account to cover the amount of that Mortgage Loan and shall solely treat such Mortgage Loan as if it were in breach of a representation or warranty; provided that the aggregate Stated Principal Balance of such Mortgage Loans does not exceed 1% of the Cut-off Date Balance.

(b) No later than 180 days after the Closing Date, (with respect to the Mortgage Loans), the related Custodian will review, for the benefit of the Bondholders, the Mortgage Files and will execute and deliver or cause to be executed and delivered to the Seller, a Final Certification in the form annexed hereto as Exhibit H. In conducting such review, the related Custodian will ascertain whether an original of each document described in subclauses (b)(ii)-(iv) of Section 2.1 of the Mortgage Loan Purchase Agreement with respect to the Mortgage Loans, required to be recorded has been returned from the recording office with evidence of recording thereon or a certified copy has been obtained from the recording office. If the related Custodian finds any document constituting part of the Mortgage File has not been received, or to be unrelated, determined on the basis of the Mortgagor name, original principal balance and loan number, to the Mortgage Loans identified in Exhibit B to this Indenture or to appear defective on its face, the related Custodian shall promptly notify the Seller.

(c) Upon deposit of the Repurchase Price in the Payment Account, the related Custodian shall release to the Seller the related Mortgage File and the Indenture Trustee shall execute and deliver all instruments of transfer or assignment, without recourse, furnished to it by the Seller as are necessary to vest in the Seller title to and rights under the related Mortgage Loan. Such purchase shall be deemed to have occurred on the date on which certification of the deposit of the Repurchase Price in the Payment Account was received by the Indenture Trustee. The related Custodian shall amend the applicable Mortgage Loan Schedule to reflect such repurchase and shall promptly notify the Master Servicer and the Rating Agencies of such amendment.

Section 2.04 Acceptance of Derivative Contracts and Special Certificate Cap Contract by Indenture Trustee. The Indenture Trustee acknowledges receipt of the Derivative Contracts and the Special Certificate Cap Contract and declares that it holds and will continue to hold these documents and any amendments, replacements or supplements thereto and all other assets of the Trust Estate as Indenture Trustee in trust for the use and benefit of all present and future Holders of the Bonds. The Indenture Trustee shall enforce the Derivative Contracts and the Special Certificate Cap Contract in accordance with their terms. The Issuer hereby directs the Indenture Trustee to execute, not in its individual capacity, but solely as Indenture Trustee on behalf of the Trust, and deliver the Derivative Contracts and the Special Certificate Cap Contract.

The Issuer hereby initially appoints the Indenture Trustee to serve as its agent for the foregoing purposes. If at any time the Issuer shall fail to maintain any such office or agency or shall fail to furnish the Indenture Trustee with the address thereof, such surrenders may be made at the office of the Indenture Trustee located at c/o DTC Transfer Services, 55 Water Street, Jeanette Park Entrance, New York, New York 10041, and notices and demands may be made or served at the Corporate Trust Office, and the Issuer hereby appoints the Indenture Trustee as its agent to receive all such surrenders, notices and demands.

Section 3.03 Money for Payments To Be Held in Trust; Paying Agent. (a) As provided in Section 3.01, all payments of amounts due and payable with respect to any Bonds that are to be made from amounts withdrawn from the Payment Account pursuant to Section 3.01 shall be made on behalf of the Issuer by the Indenture Trustee or by the Paying Agent, and no amounts so withdrawn from the Payment Account for payments of Bonds shall be paid over to the Issuer except as provided in this Section 3.03. The Issuer hereby appoints the Indenture Trustee as its Paying Agent.

The Issuer will cause each Paying Agent other than the Indenture Trustee to execute and deliver to the Indenture Trustee an instrument in which such Paying Agent shall agree with the Indenture Trustee (and if the Indenture Trustee acts as Paying Agent it hereby so agrees), subject to the provisions of this Section 3.03, that such Paying Agent will:

(i) hold all sums held by it for the payment of amounts due with respect to the Bonds in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided and pay such sums to such Persons as herein provided;

(ii) give the Indenture Trustee notice of any default by the Issuer of which it has actual knowledge in the making of any payment required to be made with respect to the Bonds;

(iii) at any time during the continuance of any such default, upon the written request of the Indenture Trustee, forthwith pay to the Indenture Trustee all sums so held in trust by such Paying Agent;

(iv) immediately resign as Paying Agent and forthwith pay to the Indenture Trustee all sums held by it in trust for the payment of Bonds if at any time it ceases to meet the standards required to be met by a Paying Agent at the time of its appointment;

(v) comply with all requirements of the Code with respect to the withholding from any payments made by it on any Bonds of any applicable withholding taxes imposed thereon and with respect to any applicable reporting requirements in connection therewith; and

(vi) not commence a bankruptcy proceeding against the Issuer in connection with this Indenture.

The Issuer may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, by Issuer Request direct any Paying Agent to pay to the Indenture Trustee all sums held in trust by such Paying Agent, such sums to be held by the Indenture Trustee upon the same trusts as those upon which the sums were held by such Paying Agent; and upon such payment by any Paying Agent to the Indenture Trustee, such Paying Agent shall be released from all further liability with respect to such money.

Subject to applicable laws with respect to escheat of funds, any money held by the Indenture Trustee or any Paying Agent in trust for the payment of any amount due with respect to any Bond and remaining unclaimed for one year after such amount has become due and payable shall be discharged from such trust and be paid to the Issuer on Issuer Request; and the Holder of such Bond shall thereafter, as an unsecured general creditor, look only to the Issuer for payment thereof (but only to the extent of the amounts so paid to the Issuer), and all liability of the Indenture Trustee or such Paying Agent with respect to such trust money shall thereupon cease; provided, however, that the Indenture Trustee or such Paying Agent, before being required to make any such repayment, shall at the expense and direction of the Issuer cause to be published once, in an Authorized Newspaper published in the English language, notice that such money remains unclaimed and that, after a date specified therein which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then remaining will be repaid to the Issuer. The Indenture Trustee may also adopt and employ, at the expense and direction of the Issuer, any other reasonable means of notification of such repayment (including, but not limited to, mailing notice of such repayment to Holders whose Bonds have been called but have not been surrendered for redemption or whose right to or interest in monies due and payable but not claimed is determinable from the records of the Indenture Trustee or of any Paying Agent, at the last address of record for each such Bondholder).

Section 3.04 Existence. The Issuer will keep in full effect its existence, rights and franchises as a statutory trust under the laws of the State of Delaware (unless it becomes, or any successor Issuer hereunder is or becomes, organized under the laws of any other state or of the United States of America, in which case the Issuer will keep in full effect its existence, rights and franchises under the laws of such other jurisdiction) and will obtain and preserve its qualification

to do business in each jurisdiction in which such qualification is or shall be necessary to protect the validity and enforceability of this Indenture, the Bonds, the Mortgage Loans and each other instrument or agreement included in the Trust Estate.

Section 3.05 Payment of Principal and Interest. (a) On each Payment Date from amounts on deposit in the Payment Account in accordance with Section 8.02 hereof, the Indenture Trustee shall pay to the Persons specified below, to the extent provided therein, the Available Funds, the Class 1-A-1B Derivative Payment and the Guaranteed Amount for such Payment Date.

ARTICLE IV

The Bonds; Satisfaction and Discharge of Indenture

Section 4.01 The Bonds. Each Class of Bonds shall be registered in the name of a nominee designated by the Depository. Beneficial Owners will hold interests in the Bonds through the book-entry facilities of the Depository in minimum initial Bond Principal Balances or Notional Amounts of $25,000 and integral multiples of $1 in excess thereof.

The Indenture Trustee may for all purposes (including the making of payments due on the Bonds) deal with the Depository as the authorized representative of the Beneficial Owners with respect to the Bonds for the purposes of exercising the rights of Holders of the Bonds hereunder. Except as provided in the next succeeding paragraph of this Section 4.01, the rights of Beneficial Owners with respect to the Bonds shall be limited to those established by law and agreements between such Beneficial Owners and the Depository and Depository Participants. Except as provided in Section 4.08 hereof, Beneficial Owners shall not be entitled to definitive certificates for the Bonds as to which they are the Beneficial Owners. Requests and directions from, and votes of, the Depository as Holder of the Bonds 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 Bondholders and give notice to the Depository of such record date. Without the consent of the Issuer and the Indenture Trustee, no Bond may be transferred by the Depository except to a successor Depository that agrees to hold such Bond 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 Issuer 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 Bonds it beneficially owns in the manner prescribed in Section 4.08.

The Bonds shall, on original issue, be executed on behalf of the Issuer by the Owner Trustee, not in its individual capacity but solely as Owner Trustee, authenticated by the Indenture Trustee and delivered by the Indenture Trustee to or upon the order of the Issuer.

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

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

Subject to the foregoing, at the option of the Bondholders, Bonds may be exchanged for other Bonds of like tenor and in authorized initial Bond Principal Balances evidencing the same Class and aggregate Percentage Interests upon surrender of the Bonds to be exchanged at the Corporate Trust Office of the Bond Registrar. Whenever any Bonds are so surrendered for exchange, the Issuer shall execute and the Indenture Trustee shall authenticate and deliver the Bonds which the Bondholder making the exchange is entitled to receive. Each Bond presented or surrendered for registration of transfer or exchange shall (if so required by the Bond Registrar) be duly endorsed by, or be accompanied by a written instrument of transfer in form reasonably satisfactory to the Bond 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. Bonds delivered upon any such transfer or exchange will evidence the same obligations, and will be entitled to the same rights and privileges, as the Bonds surrendered.

No service charge shall be made for any registration of transfer or exchange of Bonds, but the Bond 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 Bonds.

The Issuer hereby appoints the Indenture Trustee as (i) 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 and (ii) Bond Registrar under this Indenture. The Indenture Trustee hereby accepts such appointments.

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

Upon the issuance of any replacement Bond under this Section 4.03, the Issuer may require the payment by the Holder of such Bond 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 Bond issued pursuant to this Section 4.03 in replacement of any mutilated, destroyed, lost or stolen Bond shall constitute an original additional contractual obligation of the Issuer, whether or not the mutilated, destroyed, lost or stolen Bond 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 Bonds 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 Bonds.

Section 4.04 Persons Deemed Owners. Prior to due presentment for registration of transfer of any Bond, the Issuer, the Indenture Trustee, the Paying Agent and any agent of the Issuer or the Indenture Trustee may treat the Person in whose name any Bond is registered (as of the day of determination) as the owner of such Bond for the purpose of receiving payments of principal of and interest, if any, on such Bond and for all other purposes whatsoever, whether or not such Bond be overdue, and neither the Issuer, the Indenture Trustee, the Paying Agent nor any agent of the Issuer or the Indenture Trustee shall be affected by notice to the contrary.

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

Section 4.06 Book-Entry Bonds. The Bonds, upon original issuance, will be issued in the form of typewritten Bonds representing the Book-Entry Bonds, to be delivered to The Depository Trust Company, the initial Depository, by, or on behalf of, the Issuer. The Bonds shall initially be registered on the Bond Register in the name of Cede & Co., the nominee of the initial Depository, and no Beneficial Owner will receive a Definitive Bond representing such Beneficial Owner’s interest in such Bond, except as provided in Section 4.08. With respect to such Bonds, unless and until definitive, fully registered Bonds (the “Definitive Bonds”) 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 Bond Registrar, the Paying Agent 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 Bonds and the giving of instructions or directions hereunder) as the sole Holder of the Bonds, and shall have no obligation to the Beneficial Owners of the Bonds;

(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 Bonds and the Depository and/or the Depository Participants. Unless and until Definitive Bonds 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 Bonds to such Depository Participants; and

(v) whenever this Indenture requires or permits actions to be taken based upon instructions or directions of Holders of Bonds evidencing a specified percentage of the Bond Principal Balances of the Bonds, the Depository shall be deemed to represent such percentage with respect to the Bonds 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 Bonds and has delivered such instructions to the Indenture Trustee.

Section 4.07 Notices to Depository. Whenever a notice or other communication to the Bondholders is required under this Indenture, unless and until Definitive Bonds 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 Bonds to the Depository, and shall have no obligation to the Beneficial Owners.

Section 4.08 Definitive Bonds. If (i) the Indenture Trustee determines that the Depository is no longer willing or able to properly discharge its responsibilities with respect to the Bonds and the Indenture Trustee is unable to locate a qualified successor, (ii) the Indenture Trustee elects to terminate the book-entry system through the Depository or (iii) after the occurrence of an Event of Default, Beneficial Owners of Bonds representing beneficial interests aggregating at least a majority of the Bond Principal Balances of the Bonds 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 Bonds to Beneficial Owners requesting the same. Upon surrender to the Indenture Trustee of the typewritten Bonds representing the Book-Entry Bonds by the Depository, accompanied by registration instructions, the Issuer shall execute and the Indenture Trustee shall authenticate the Definitive Bonds in accordance with the instructions of the Depository. None of the Issuer, the Bond 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 Bonds, the Indenture Trustee shall recognize the Holders of the Definitive Bonds as Bondholders.

Section 4.09 Tax Treatment. The Issuer has entered into this Indenture, and the Bonds will be issued with the intention that, for federal, state and local income, single business and franchise tax purposes, the Bonds will qualify as indebtedness. The Issuer and the Indenture Trustee (in accordance with Section 6.06 hereof), by entering into this Indenture, and each Bondholder, by its acceptance of its Bond (and each Beneficial Owner by its acceptance of an interest in the applicable Book-Entry Bond), agree to treat the Bonds for federal, state and local income, single business and franchise tax purposes as indebtedness.

Section 4.10 Satisfaction and Discharge of Indenture.

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

Section 4.12 Repayment of Monies Held by Paying Agent. In connection with the satisfaction and discharge of this Indenture with respect to the Bonds, all monies then held by any Person other than the Indenture Trustee under the provisions of this Indenture with respect to such Bonds shall, upon demand of the Issuer, be paid to the Indenture Trustee to be held and applied according to Section 3.05 and thereupon such Person shall be released from all further liability with respect to such monies.

After the preparation of the Definitive Bonds, the temporary Bonds shall be exchangeable for Definitive Bonds upon surrender of the temporary Bonds at the office of the Indenture Trustee’s agent located at DTC Transfer Services, located at 55 Water Street, Jeanette Park Entrance, New York, New York 10041, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Bonds, the Issuer shall execute and the

Indenture Trustee shall authenticate and make available for delivery, in exchange therefor, Definitive Bonds of authorized denominations and of like tenor, class and aggregate principal amount.

ARTICLE V

Default and Remedies

Section 5.01 Events of Default. The Issuer shall deliver to the Indenture Trustee, 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) or (iv) of the definition of “Event of Default”, its status and what action the Issuer is taking or proposes to take with respect thereto. The Indenture Trustee shall not be deemed to have knowledge of any Event of Default unless a Responsible Officer has actual knowledge thereof or unless written notice of such Event of Default is received by a Responsible Officer and such notice references the Bonds, the Trust Estate or this Indenture.

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

At any time after such declaration of acceleration of maturity with respect to an Event of Default has been made and before a judgment or decree for payment of the money due has been obtained by the Indenture Trustee as hereinafter in this Article V provided, the Holders of the Bonds representing not less than a majority of the aggregate Bond Principal Balance of the Bonds (other than the Class 1-A-IO Bonds) and not less than a majority of the aggregate Notional Amount of the Class 1-A-IO Bonds, by written notice to the Issuer and the Indenture Trustee, may waive the related Event of Default and rescind and annul such declaration and its consequences if

(i) the Issuer has paid or deposited with the Indenture Trustee a sum sufficient to pay:

(A)	all payments of principal of and interest on the Bonds and all other amounts that would then be due hereunder or upon the Bonds if the Event of Default giving rise to such acceleration had not occurred;
(B)	all sums paid or advanced by the Indenture Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Indenture Trustee and its agents and counsel; and
(C)	all amounts owed to the Derivative Contract Counterparties;

(ii) all Events of Default, other than the nonpayment of the principal of the Bonds 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 Issuer covenants that if (i) default is made in the payment of any interest on any Bond 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 Bond when the same becomes due and payable, the Issuer shall, upon demand of the Indenture Trustee, at the direction of the Holders of a majority of the aggregate Bond Principal Balances of the Bonds, pay to the Indenture Trustee, for the benefit of the Holders of Bonds, the whole amount then due and payable on the Bonds for principal and interest, with interest at the applicable Bond Interest Rate upon the overdue principal, and in addition thereto such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Indenture Trustee and its agents and counsel.

(b) In case the Issuer 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 10.16 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 Issuer or other obligor upon the Bonds and collect in the manner provided by law out of the property of the Issuer or other obligor the Bonds, 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 10.16 hereof may, as more particularly provided in Section 5.04 hereof, in its discretion, proceed to protect and enforce its rights and the rights of the Bondholders, by such appropriate Proceedings, as directed in writing by the Holders of a majority of the aggregate Bond Principal Balances of the Bonds, 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 Issuer or any other obligor upon the Bonds 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 Issuer or its property or such other obligor or Person, or in case of any other comparable judicial Proceedings relative to the Issuer or other obligor upon the Bonds, or to the creditors or property of the Issuer or such other obligor, the Indenture Trustee, as directed in writing by the Holders of a majority of the aggregate Bond Principal Balances of the Bonds,

irrespective of whether the principal of any Bonds 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 Bonds 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 Bondholders allowed in such Proceedings;

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

(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 Bondholder any plan of reorganization, arrangement, adjustment or composition affecting the Bonds or the rights of any Holder thereof or to authorize the Indenture Trustee to vote in respect of the claim of any Bondholder 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 Bonds, may be enforced by the Indenture Trustee without the possession of any of the Bonds 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 Bonds, subject to Section 5.05 hereof.

(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 Bonds, and it shall not be necessary to make any Bondholder a party to any such Proceedings.

Section 5.04 Remedies; Priorities. (a) If an Event of Default shall have occurred and be continuing and if an acceleration has been declared and not rescinded pursuant to Section 5.02 hereof, the Indenture Trustee subject to the provisions of Section 10.16 hereof may, and shall, at the written direction of the Holders of a majority of the aggregate Bond Principal Balances of the Bonds, do one or more of the following (subject to Section 5.05 hereof):

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

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

(iii) exercise any remedies of a secured party under the UCC and take any other appropriate action to protect and enforce the rights and remedies of the Indenture Trustee and the Holders of the Bonds; 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 Bond Principal Balance of the Bonds and 50% of the aggregate Notional Amount of the Class 1-A-IO Bonds, (B) the proceeds of such sale or liquidation distributable to the Holders of the Bonds are sufficient to discharge in full all amounts then due and unpaid upon such Bonds for principal and interest or (C) the Indenture Trustee determines that the Mortgage Loans will not continue to provide sufficient funds for the payment of principal of and interest on the applicable Bonds as they would have become due if the Bonds had not been declared due and payable, and the Indenture Trustee obtains the consent of the Holders of a majority of the aggregate Bond Principal Balance of the Bonds and a majority of the aggregate Notional Amount of the Class 1-A-IO Bonds. In determining such sufficiency or insufficiency with respect to clause (B) and (C), the Indenture Trustee may, but need not, obtain and rely upon an opinion (obtained at the expense of the Trust) of an Independent investment banking or accounting firm of national reputation as to the feasibility of such proposed action and as to the sufficiency of the Trust Estate for such purpose. Notwithstanding the foregoing, 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.

If the Bonds have been declared to be due and payable under Section 5.02 following an Event of Default and such declaration and its consequences have not been rescinded and annulled, the Indenture Trustee may elect to take and maintain possession of the Trust Estate. It is the desire of the parties hereto and the Bondholders that there be at all times sufficient funds for the payment of principal of and interest on the Bonds and other obligations of the Issuer 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 Bondholder of any Bond 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 10.16 hereof,

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

(ii) the Holders of not less than 25% of the aggregate Bond Principal Balances of the Bonds (for which purpose the Class 1-A-IO Bonds will be deemed to have an aggregate Bond Principal Balance equal to 5% of the aggregate Bond Principal Balance of the other Classes of Bonds) have made a written request to the Indenture Trustee to institute such Proceeding in respect of such Event of Default in its own name as Indenture Trustee hereunder;

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

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

(v) no direction inconsistent with such written request has been given to the Indenture Trustee during such 60-day period by the Holders of a majority of the Bond Principal Balances of the Bonds and a majority of the aggregate Notional Amount of the Class 1-A-IO Bonds.

It is understood and intended that no one or more Holders of Bonds 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 Bonds 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.

Subject to the last paragraph of Section 5.11 herein, in the event the Indenture Trustee shall receive conflicting or inconsistent requests and indemnity from two or more groups of Holders of Bonds, each representing less than a majority of the Bond Principal Balances or Notional Amounts of the Bonds, 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 Bondholders To Receive Principal and Interest. Notwithstanding any other provisions in this Indenture, the Holder of any Bond shall have the right, which is absolute and unconditional, to receive payment of the interest and, with respect to all of the Bonds other than the Class 1-A-IO Bonds, principal, if any, on such Bond on or after the respective due dates thereof expressed in such Bond 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 Bondholder.

Section 5.08 Restoration of Rights and Remedies. If the Indenture Trustee or any Bondholder 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 Bondholder, then and in every such case the Issuer, the Indenture Trustee and the Bondholders 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 Bondholders 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 Bondholders 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 Bond 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 Bondholders may be exercised from time to time, and as often as may be deemed expedient, by the Indenture Trustee or by the Bondholders, as the case may be.

Section 5.11 Control By Bondholders. The Holders of a majority of the aggregate Bond Principal Balances of the Bonds (other than the Class 1-A-IO Bonds) and a majority of the aggregate Notional Amount of the Class 1-A-IO Bonds 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 Bonds or exercising any trust or power conferred on the Indenture Trustee; provided that:

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

(ii) any direction to the Indenture Trustee to sell or liquidate the Trust Estate shall be by Holders of Bonds representing not less than 100% of the Bond Principal Balances of the Bonds (for which purpose the Class 1-A-IO Bonds will be deemed to have a Bond Principal Balance equal to 5% of the aggregate Bond Principal Balance of the other Classes of Bonds); and

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

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

Section 5.12 Waiver of Past Defaults. Prior to the declaration of the acceleration of the maturity of the Bonds as provided in Section 5.02 hereof, the Holders of Bonds representing not less than a majority of the aggregate Bond Principal Balance or Notional Amounts of the Bonds 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 Bonds or (b) in respect of a covenant or provision hereof which cannot be modified or amended without the consent of the Holder of each Bond. In the case of any such waiver, the Issuer, the Indenture Trustee and the Holders of the Bonds 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 Bond and each Beneficial Owner of any interest therein by such Holder’s or Beneficial Owner’s acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Indenture Trustee for any action taken, suffered or omitted by it as

Indenture Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section 5.13 shall not apply to (a) any suit instituted by the Indenture Trustee, (b) any suit instituted by any Bondholder, or group of Bondholders, in each case holding in the aggregate more than 10% of the Bond Principal Balances of the Bonds (for which purpose the Class 1-A-IO Bonds will be deemed to have a Bond Principal Balance equal to 5% of the aggregate Bond Principal Balance of the other Classes of Bonds) or (c) any suit instituted by any Bondholder for the enforcement of the payment of principal of or interest on any Bond on or after the respective due dates expressed in such Bond and in this Indenture.

Section 5.14 Waiver of Stay or Extension Laws. The Issuer 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 Issuer (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it shall not hinder, delay or impede the execution of any power herein granted to the Indenture Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

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

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

(1) the Holders of all Bonds 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 Bondholders under the Bonds on the Payment Date next succeeding the date of such Sale, or

(3) the Indenture Trustee determines that the conditions for retention of the Trust Estate set forth in Section 5.05 hereof cannot be satisfied (in making any such determination, the Indenture Trustee may rely upon an opinion of an Independent investment banking firm obtained and delivered as provided in Section 5.05 hereof) the Holders of Bonds representing at least 100% of the Bond Principal Balances of the Bonds (for which purpose the Class 1-A-IO Bonds will be deemed to have a Bond Principal

Balance equal to 5% of the aggregate Bond Principal Balance of the other Classes of Bonds) 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 representing at least 66-2/3% of the Bond Principal Balances of the Bonds (for which purpose the Class 1-A-IO Bonds will be deemed to have a Bond Principal Balance equal to 5% of the aggregate Bond Principal Balance of the other Classes of Bonds) have otherwise consented or directed the Indenture Trustee, at any public Sale of all or any portion of the Trust Estate at which a minimum bid equal to or greater than the amount described in paragraph (2) of subsection (b) of this Section 5.15 has not been established by the Indenture Trustee and no Person bids an amount equal to or greater than such amount, the Indenture Trustee, as trustee for the benefit of the Holders of the Bonds, 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 Bonds may bid for and purchase the property offered for sale, and upon compliance with the terms of sale may hold, retain and possess and dispose of such property, without further accountability, and may, in paying the purchase money therefor, deliver any Bonds 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 Bonds, 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 Bonds and Holders of Certificates as a result of such Sale in accordance with Section 5.04(b) hereof 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 Bonds in order to complete any such Sale or in order for the net Sale price to be credited against such Bonds, and any property so acquired by the Indenture Trustee shall be held and dealt with by it in accordance with the provisions of this Indenture;

(3) the Indenture Trustee shall execute and deliver an appropriate instrument of conveyance, prepared by the Issuer and satisfactory to the Indenture Trustee, 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 Issuer 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

Section 5.16 Action on Bonds. The Indenture Trustee’s right to seek and recover judgment on the Bonds 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 Bondholders shall be impaired by the recovery of any judgment by the Indenture Trustee against the Issuer 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 Issuer. Any money or property collected by the Indenture Trustee shall be applied in accordance with Section 5.04(b) hereof.

Section 5.17 Performance and Enforcement of Certain Obligations. (a) Promptly following a request from the Indenture Trustee to do so, the Issuer in its capacity as Holder of the Mortgage Loans, shall take all such lawful action as the Indenture Trustee may request to cause the Issuer to compel or secure the performance and observance by the Seller and the Master Servicer, as applicable, of each of their obligations to the Issuer 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 Issuer 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 Seller or the Master Servicer thereunder and the institution of legal or administrative actions or proceedings to compel or secure performance by the Seller or the Master Servicer of each of their obligations under the Mortgage Loan Purchase Agreement and the Servicing Agreement.

The Indenture Trustee in its individual or any other capacity may become the owner or pledgee of Bonds and may otherwise deal with the Issuer or its Affiliates with the same rights it would have if it were not Indenture Trustee, subject to the requirements of the Trust Indenture Act. Any Bond Registrar, co-registrar or co-paying agent may do the same with like rights. However, the Indenture Trustee must comply with Sections 6.11 and 6.12 hereof.

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 Bonds, it shall not be accountable for the Issuer’s use of the proceeds from the Bonds, and it shall not be responsible for any statement of the Issuer in the Indenture or in any document issued in connection with the sale of the Bonds or in the Bonds other than the Indenture Trustee’s certificate of authentication.

Section 6.05 Notice of Event of Default. Subject to Section 5.01, the Indenture Trustee shall promptly mail to each Bondholder notice of the Event of Default after it is known to a Responsible Officer of the Indenture Trustee, unless such Event of Default shall have been waived or cured. Except in the case of an Event of Default in payment of principal of or interest on any Bond, the Indenture Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of Bondholders.

Section 6.06 Reports by Indenture Trustee to Bondholders and Tax Administration. The Indenture Trustee shall deliver to each Bondholder such information as may be required to enable such Holder to prepare its federal and state income tax returns.

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

Section 6.07 Compensation and Indemnity. The Issuer shall pay to the Indenture Trustee on each Payment Date reasonable compensation for its services. On each Payment Date,

the Indenture Trustee shall pay itself from amounts available therefore on deposit in the Payment Account for such Payment Date all amounts owing to the Indenture Trustee hereunder (including amounts owing from the Issuer for indemnification and otherwise) as provided in Section 3.05(d)(vi), Section 5.04(b) and Section 8.02(c) hereof and Appendix A hereto. The Indenture Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Issuer shall reimburse the Indenture Trustee for all reasonable out-of-pocket expenses incurred or made by it, including costs of collection, in addition to compensation for its services. Such expenses shall include reasonable compensation and expenses, disbursements and advances of the Indenture Trustee’s agents, counsel, accountants and experts. The Issuer shall indemnify the Indenture Trustee against any and all loss, liability or expense (including attorneys’ fees) incurred by it in connection with the administration of this Trust and the performance of its duties hereunder. The Indenture Trustee shall notify the Issuer promptly of any claim for which it may seek indemnity. Failure by the Indenture Trustee to so notify the Issuer shall not relieve the Issuer of its obligations hereunder. The Issuer shall defend any such claim, and the Indenture Trustee may have separate counsel and the Issuer shall pay the fees and expenses of such counsel. The Issuer is not obligated to 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 Issuer’s payment obligations to the Indenture Trustee pursuant to this Section 6.07 shall survive the discharge of this Indenture and the termination or resignation of the Indenture Trustee. When the Indenture Trustee incurs expenses after the occurrence of an Event of Default with respect to the Issuer, the expenses are intended to constitute expenses of administration under Title 11 of the United States Code or any other applicable federal or state bankruptcy, insolvency or similar law.

Section 6.08 Replacement of Indenture Trustee. No resignation or removal of the Indenture Trustee and no appointment of a successor Indenture Trustee shall become effective until the acceptance of appointment by the successor Indenture Trustee pursuant to this Section 6.08. The Indenture Trustee may resign at any time by so notifying the Issuer. The Holders of a majority of Bond Principal Balances of the Bonds may remove the Indenture Trustee by so notifying the Indenture Trustee and may appoint a successor Indenture Trustee. The Issuer shall remove the Indenture Trustee if:

(i)	the Indenture Trustee fails to comply with Section 6.11 hereof;
(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 the Indenture Trustee for any reason (the Indenture Trustee in such event being referred to herein as the retiring Indenture Trustee), the Issuer 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 Issuer. 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 Bondholders. The retiring Indenture Trustee shall promptly transfer all property held by it as Indenture Trustee to the successor Indenture Trustee.

If a successor Indenture Trustee does not take office within 60 days after the retiring Indenture Trustee resigns or is removed, the retiring Indenture Trustee, the Issuer or the Holders of a majority of Bond Principal Balances of the Bonds may petition any court of competent jurisdiction for the appointment of a successor Indenture Trustee.

Notwithstanding the replacement of the Indenture Trustee pursuant to this Section, the Issuer’s obligations under Section 6.07 shall continue for the benefit of the retiring Indenture Trustee.

Section 6.09 Successor Indenture Trustee by Merger. If the Indenture Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business or assets to, another corporation or banking association, the resulting, surviving or transferee corporation, without any further act, shall be the successor Indenture Trustee; provided, that such corporation or banking association shall be otherwise qualified and eligible under Section 6.11 hereof. The Indenture Trustee shall provide the Rating Agencies with prior written notice of any such transaction.

If at the time such successor or successors by merger, conversion or consolidation to the Indenture Trustee shall succeed to the trusts created by this Indenture and any of the Bonds shall have been authenticated but not delivered, any such successor to the Indenture Trustee may adopt the certificate of authentication of any predecessor trustee and deliver such Bonds so authenticated; and if at that time any of the Bonds shall not have been authenticated, any successor to the Indenture Trustee may authenticate such Bonds either in the name of any predecessor hereunder or in the name of the successor to the Indenture Trustee; and in all such cases such certificates shall have the full force which it is in the Bonds or in this Indenture provided that the certificate of the Indenture Trustee shall have.

Section 6.10 Appointment of Co-Indenture Trustee or Separate Indenture Trustee. (a) Notwithstanding any other provisions of this Indenture, at any time, for the purpose of meeting any legal requirement of any jurisdiction in which any part of the Trust Estate may at the time be located, the Indenture Trustee shall have the power and may execute and deliver all instruments to appoint one or more Persons to act as a co-trustee or co-trustees, or separate trustee or separate trustees, of all or any part of the Trust Estate, and to vest in such Person or Persons, in such capacity and for the benefit of the Bondholders, such title to the Trust Estate, or any part hereof, and, subject to the other provisions of this Section, such powers, duties, obligations, rights and trusts as the Indenture Trustee may consider necessary or desirable. No co-trustee or separate trustee hereunder shall be required to meet the terms of eligibility as a successor trustee under Section 6.11 hereof and no notice to the Bondholders of the appointment of any co-trustee or separate trustee shall be required under Section 6.08 hereof.

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

(i) all rights, powers, duties and obligations conferred or imposed upon the Indenture Trustee shall be conferred or imposed upon and exercised or performed by the Indenture Trustee and such separate trustee or co-trustee jointly (it being understood that such separate trustee or co-trustee is not authorized to act separately without the Indenture Trustee joining in such act), except to the extent that under any law of any jurisdiction in which any particular act or acts are to be performed the Indenture Trustee shall be incompetent or unqualified to perform such act or acts, in which event such rights, powers, duties and obligations (including the holding of title to the Trust Estate or any portion thereof in any such jurisdiction) shall be exercised and performed singly by such separate trustee or co-trustee, but solely at the direction of the Indenture Trustee;

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

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

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

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

(vii) to evidence and provide for the acceptance of the appointment hereunder by a successor trustee with respect to the Bonds and to add to or change any of the provisions of this Indenture as shall be necessary to facilitate the administration of the trusts hereunder by more than one trustee, pursuant to the requirements of Article VI hereof; 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 as to the enforceability of any such indenture supplement and to the effect that (i) such indenture supplement is permitted hereunder and (ii)

entering into such indenture supplement will not result in a “substantial modification” of the Bonds under Treasury Regulation Section 1.1001-3 or adversely affect the status of the Bonds as indebtedness for federal income tax purposes.

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 Issuer and the Indenture Trustee, when authorized by an Issuer Request, may, also without the consent of any of the Holders of the Bonds but with prior notice to the Rating Agencies, enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions to, or changing in any manner or eliminating any of the provisions of, this Indenture or of modifying in any manner the rights of the Holders of the Bonds under this Indenture; provided, however, that such action as evidenced by an Opinion of Counsel, (i) is permitted by this Indenture, and shall not (ii) adversely affect in any material respect the interests of any Bondholder or (iii) if 100% of the Certificates are not owned by IMH Assets Corp., cause the Issuer to be subject to an entity level tax for federal income tax purposes.

Section 9.02 Supplemental Indentures With Consent of Bondholders. The Issuer and the Indenture Trustee, when authorized by an Issuer Request, also may, with prior notice to the Rating Agencies and, with the consent of the Holders of not less than a majority of the Bond Principal Balance or Notional Amounts of each Class of Bonds affected thereby, by Act (as defined in Section 10.03 hereof) of such Holders delivered to the Issuer 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 Bonds under this Indenture; provided, however, that no such supplemental indenture shall, without the consent of the Holder of each Bond affected thereby:

(i) change the date of payment of any installment of principal of or interest on any Bond, 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 Bonds, or change any place of payment where, or the coin or currency in which, any Bond 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 Bonds on or after the respective due dates thereof;

(ii) reduce the percentage of the Bond Principal Balances of the Bonds, 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 “Bondholder”

(iv) reduce the percentage of the Bond Principal Balances of the Bonds required to direct the Indenture Trustee to direct the Issuer to sell or liquidate the Trust Estate pursuant to Section 5.04 hereof;

(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 Bond 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 Bond 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 Bond 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 Issuer (if 100% of the Certificates are not owned by IMH Assets Corp.) to be subject to an entity level tax.

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

No supplemental indenture adverse to the interests of the Derivative Contract Counterparties shall be entered into without the related Derivative Contract Counterparty’s written consent.

It shall not be necessary for any Act of Bondholders 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 Issuer and the Indenture Trustee of any supplemental indenture pursuant to this Section 9.02, the Indenture Trustee shall mail to the Holders of the Bonds 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 hereof, 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 Bonds affected thereby, and the respective rights, limitations of rights, obligations, duties, liabilities and immunities under this Indenture of the Indenture Trustee, the Issuer and the Holders of the Bonds 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 Bonds to Supplemental Indentures. Bonds 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 Issuer or the Indenture Trustee shall so determine, new Bonds so modified as to conform, in the opinion of the Indenture Trustee and the Issuer, to any such supplemental indenture may be prepared and executed by the Issuer and authenticated and delivered by the Indenture Trustee in exchange for Outstanding Bonds.

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

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

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

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

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

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

(6) (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 Issuer shall, in addition to any obligation imposed in Section 10.01 (a) or elsewhere in this Indenture, furnish to the Indenture Trustee an Officer’s Certificate certifying or stating the opinion of each person signing such certificate as to the fair value (within 90 days prior to such deposit) to the Issuer of the Collateral or other property or securities to be so deposited and a report from a nationally recognized accounting firm verifying such value.

(ii) Whenever the Issuer 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 Issuer shall also deliver to the Indenture Trustee an Independent Certificate from a nationally recognized accounting firm as to the same matters, if the fair value 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 Issuer, as set forth in the certificates delivered pursuant to clause (i) above and this clause (ii), is 10% or more of the Bond Principal Balances or Notional Amounts of the Bonds, but such a certificate need not be furnished with respect to any securities so deposited, 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 Bond Principal Balances or Notional Amounts of the Bonds.

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

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 Issuer may be based, insofar as it relates to legal matters, upon a certificate or opinion of, or representations by, counsel, unless such officer knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to the matters upon which his certificate or opinion is based are erroneous. Any such certificate of an Authorized Officer or Opinion of Counsel may be based, insofar as it relates to factual matters, upon a certificate or opinion of, or representations by, an officer or officers of the Seller or the Issuer, stating that the information with respect to such factual matters is in the possession of the Seller or the Issuer, 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 Issuer shall deliver any document as a condition of the granting of such application, or as evidence of the Issuer’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 Issuer 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 Bondholders. (a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Bondholders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Bondholders 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 Issuer. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Bondholders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and (subject to Section 6.01 hereof) conclusive in favor of the Indenture Trustee and the Issuer, if made in the manner provided in this Section 10.03 hereof.

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

(d) Any request, demand, authorization, direction, notice, consent, waiver or other action by the Holder of any Bonds shall bind the Holder of every Bond 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 Issuer in reliance thereon, whether or not notation of such action is made upon such Bond.

Section 10.04 Notices etc., to Indenture Trustee, Issuer, Seller and Rating Agencies. Any request, demand, authorization, direction, notice, consent, waiver or Act of Bondholders 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 Bondholders is to be made upon, given or furnished to or filed with:

(i) the Indenture Trustee by any Bondholder or by the Issuer 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 Bondholders to the Issuer; or

(ii) the Issuer by the Indenture Trustee or by any Bondholder shall be sufficient for every purpose hereunder if in writing and mailed first-class, postage prepaid to the Issuer addressed to: Impac CMB Trust Series 2005-4, in care of Wilmington Trust Company, Rodney Square North, 1100 North Market Street, Wilmington, Delaware ###-###-####, Attention: Corporate Trust Administration, or at any other address previously furnished in writing to the Indenture Trustee by the Issuer. The Issuer shall promptly transmit any notice received by it from the Bondholders to the Indenture Trustee; or

(iii) the Seller by the Indenture Trustee shall be sufficient for every purpose hereunder if in writing and mailed, first-class postage pre-paid, or personally delivered or telecopied to: Impac Mortgage Holdings, Inc., 1401 Dove Street, Newport Beach, California 92660, Attention: General Counsel.

Notices required to be given to the Rating Agencies by the Issuer, the Indenture Trustee or the Owner Trustee shall be in writing, mailed first-class postage pre-paid, to (i) in the case of Moody’s, at the following address: Moody’s Investors Service, Inc., Residential Mortgage 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, 55 Water Street, 41^st Floor, New York, New York 10041, 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 Bondholders; Waiver. Where this Indenture provides for notice to Bondholders 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 Bondholder affected by such event, at such Person’s address as it appears on the Bond 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 Bondholders is given by mail, neither the failure to mail such notice nor any defect in any notice so mailed to any particular Bondholder shall affect the sufficiency of such notice with respect to other Bondholders, 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 Bondholders 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 Bondholders

when such notice is required to be given pursuant to any provision of this Indenture, then any manner of giving such notice as shall be satisfactory to the Indenture Trustee shall be deemed to be a sufficient giving of such notice.

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

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

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

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

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

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

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

Section 10.11 GOVERNING LAW. THIS INDENTURE SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REFERENCE TO ITS CONFLICT OF LAW PROVISIONS, AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

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

Section 10.13 Recording of Indenture. If this Indenture is subject to recording in any appropriate public recording offices, such recording is to be effected by the Issuer and at its expense accompanied by an Opinion of Counsel at its expense (which may be counsel to the Indenture Trustee or any other counsel reasonably acceptable to the Indenture Trustee) to the

effect that such recording is necessary either for the protection of the Bondholders or any other Person secured hereunder or for the enforcement of any right or remedy granted to the Indenture Trustee under this Indenture.

Section 10.14 Issuer Obligation. No recourse may be taken, directly or indirectly, with respect to the obligations of the Issuer, the Owner Trustee or the Indenture Trustee on the Bonds 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 Issuer 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 Issuer, 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 Issuer hereunder, the Owner Trustee shall be subject to, and entitled to the benefits of, the terms and provisions of Article VI, VII and VIII of the Trust Agreement.

Section 10.15 No Petition. The Indenture Trustee, by entering into this Indenture, and each Bondholder, by accepting a Bond, hereby covenant and agree that they will not at any time prior to one year from the date of termination hereof, institute against the Depositor or the Issuer, or join in any institution against the Depositor or the Issuer 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 Bonds, this Indenture or any of the Basic Documents.

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

IN WITNESS WHEREOF, the Issuer and the Indenture Trustee have caused their names to be signed hereto by their respective officers thereunto duly authorized, all as of the day and year first above written.

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 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 Loans as of the end of the prior Due Period is less than or equal to 20% of the sum of the aggregate Stated Principal Balance of the Group 1 Loans as of the Cut-off Date, and (ii) the Payment Date occurring in April 2015. The Group 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 2 Loans as of the end of the prior Due Period is less than or equal to 20% of the aggregate Stated Principal Balance of the Group 2 Loans as of the Cut-off Date and (ii) the Payment Date occurring in April 2015.

The Issuer 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 Issuer, the Owner Trustee, the Indenture Trustee, IMH 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 Issuer pledged to secure the Class [_-A-_] Bonds pursuant to the Indenture and the rights conveyed to the Issuer 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 scheduled reductions in the [principal amount][Notional 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 Issuer 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] [on the Notional Amount] 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 Issuer, the Seller, 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 Issuer, the Seller, 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 Issuer, the Seller, 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 Issuer. 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 Issuer 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.

Prior to the due presentment for registration of transfer of this Bond, the Issuer, the Indenture Trustee and any agent of the Issuer 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 Issuer, the Indenture Trustee nor any such agent of the Issuer 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 Issuer and the rights of the Holders of the Bonds under the Indenture at any time by the Issuer 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 Issuer 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][Notional Amount] 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.

IN WITNESS WHEREOF, the Issuer has caused this instrument to be duly executed by Wilmington Trust Company, not in its individual capacity but solely as Owner Trustee.
