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in Section 3.01, all payments of amounts due and payable with respect to any Notes that are to be made from amounts withdrawn from the Payment Account pursuant to Section 3.01 shall be made on behalf of the Issuer by the Indenture Trustee or by the Paying Agent, and no amounts so withdrawn from the Payment Account for payments of Notes shall be paid over to the Issuer except as provided in this Section 3.03. The Issuer hereby appoints the Indenture Trustee to act as initial Paying Agent hereunder.

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 Notes 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 written 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 Notes;

(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;

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

(vi) deliver to the Indenture Trustee a copy of the Servicing Certificate prepared with respect to each Payment Date by the Servicer pursuant to Section 4.01 of the Servicing Agreement.

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 Note 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 upon receipt by the Indenture Trustee or any Paying Agent (as applicable) of an Issuer Request containing instructions to do so; and the Holder of such Note 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 payment, shall at the expense and direction of the Issuer cause to be published once, in an Authorized Newspaper, 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 paid 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 payment (including, but not limited to, mailing notice of such payment to Noteholders whose Notes 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 Noteholder).

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 Notes, the Loans and each other instrument or agreement included in the Trust Estate.

If the rate does not appear on that page or any other page as may replace that page on that service, or if the service is no longer offered, any other service for displaying LIBOR or comparable rates as may be selected by the Indenture Trustee after consultation with the Servicer, the rate will be the reference bank rate.

The Reference Bank Rate will be determined on the basis of the rates at which deposits in the U.S. Dollars are offered by the reference banks, which shall be three major banks that are engaged in transactions in the London interbank market, selected by the Indenture Trustee after consultation with the Servicer. The Reference Bank Rate will be determined as of 11:00 A.M., London time, on the LIBOR Rate Adjustment Date on the basis of rates offered by the Reference Banks to prime banks in the London interbank market for a period of one month in amounts approximately equal to the aggregate Class Principal Balance of the Class A, Class 1M-1, Class 2M and Class 2B-1 Notes. The Indenture Trustee will request the principal London office of each of the Reference Banks to provide a quotation of its rate. If at least two quotations are provided, the rate will be the arithmetic mean of the quotations. If on that date fewer than two quotations are provided as requested, the rate will be the arithmetic mean of the rates quoted by one or more major banks in New York City, selected by the Indenture Trustee after consultation with the Servicer, as of 11:00 A.M., New York City time, on that date for loans in U.S. Dollars to leading European banks for a period of one month in amounts approximately equal to the aggregate Class Principal Balance of the Class A, Class 1M-1, Class 2M and Class 2B-1 Notes. If no quotations can be obtained, the rate will be LIBOR for the prior Payment Date; provided however, if, under the priorities listed previously in this paragraph, LIBOR for a Payment Date would be based on LIBOR for the previous Payment Date for the third consecutive Payment Date, the Indenture Trustee after consultation with the Servicer shall select an alternative comparable index over which the Indenture Trustee has no control, used for determining one-month Eurodollar lending rates that is calculated and published or otherwise made available by an independent party.

The establishment of LIBOR by the Indenture Trustee and the Indenture Trustee’s subsequent calculation of the Note Interest Rate applicable to the Class A, Class 1M-1, Class 2M and Class 2B-1 Notes for the relevant Accrual Period, in the absence of manifest error, will be final and binding.

Section 3.28. Liquidation on Final Maturity Date. On the Final Maturity Date, if the Securities are not paid in full on or prior to the Final Maturity Date, the Indenture Trustee shall take full account of the assets and liabilities of the Issuer, shall liquidate the assets, in a commercially reasonable manner and on commercially reasonable terms, as promptly as is consistent with obtaining the fair value thereof and in accordance with Section 5.15, and shall apply and distribute the proceeds therefrom in the order of priority described in Section 3.05(b), (c), (d) and (e).

Section 3.29. No Recourse. Upon the occurrence of an Event of Default under the Notes, this Indenture or the other Basic Documents, Noteholders shall have recourse only to the Collateral and all proceeds thereof, as and to the extent provided herein, and no recourse shall be had by such Noteholders against the Issuer or its other assets or properties.

Section 3.30. Additional Representations. The Issuer hereby represents and warrants to the Indenture Trustee that as of the Closing Date:

(a) This Indenture creates a valid and continuing security interest (as defined in the applicable UCC) in the Mortgage Notes in favor of the Indenture Trustee, which security interest is prior to all other Liens (except as expressly permitted otherwise in this Indenture), and is enforceable as such as against creditors of and purchasers from the Issuer.

(b) The Mortgage Notes constitute “instruments” within the meaning of the applicable UCC.

(d) The original executed copy of each Mortgage Note (except for any Mortgage Note with respect to which a Lost Note Affidavit has been delivered to the Custodian) has been delivered to the Custodian.

(e) The Issuer has received a written acknowledgment from the Custodian that the Custodian is acting solely as agent of the Indenture Trustee.

(f) Other than the security interest granted to the Indenture Trustee pursuant to this Indenture, the Issuer has not pledged, assigned, sold, granted a security interest in, or otherwise conveyed any of the Mortgage Notes. The Issuer has not authorized the filing of and is not aware of any financing statements against the Issuer that include a description of collateral covering the Mortgage Notes other than any financing statement relating to the security interest granted to the Indenture Trustee hereunder or any security interest that has been terminated. The Issuer is not aware of any judgment or tax lien filings against the Issuer.

(g) None of the Mortgage Notes has any marks or notations indicating that they have been pledged, assigned or otherwise conveyed to any Person other than the Indenture Trustee, except for (i) any endorsements that are part of a complete chain of endorsements from the originator of the Mortgage Note to the Indenture Trustee, and (ii) any marks or notations pertaining to Liens that have been terminated or released.

ARTICLE IV

THE NOTES; SATISFACTION AND DISCHARGE OF INDENTURE

Section 4.01. The Notes. The Book-Entry Notes shall be registered in the name of a nominee designated by the Depository. Beneficial Owners will hold security entitlements to the Book-Entry Notes through the book-entry facilities of the Depository in minimum Initial Note Balances 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 Book-Entry Notes) deal with the Depository as the authorized representative of the Beneficial Owners with respect to the Book-Entry Notes for the purposes of exercising the rights of Holders of Book-Entry Notes hereunder. Except as provided in the next succeeding paragraph of this Section 4.01, the rights of Beneficial Owners with respect to the Book-Entry Notes shall be limited to those established by law and agreements between such Beneficial Owners and the Depository and Depository Participants. Except as provided in Section 4.08, Beneficial Owners shall not be entitled to definitive certificates for the Book-Entry Notes as to which they are the Beneficial Owners. Requests and directions from, and votes of, the Depository as Holder of the Book-Entry Notes shall not be deemed inconsistent if they are made with respect to different Beneficial Owners. The Indenture Trustee may establish a reasonable record date in connection with solicitations of consents from or voting by Holders of the Book-Entry Notes and give notice to the Depository of such record date. Without the consent of the Issuer and the Indenture Trustee, no Book-Entry Note may be transferred by the Depository except to a successor Depository that agrees to hold such Book-Entry Note for the account of the Beneficial Owners.

In the event the Depository Trust Company resigns or is removed as Depository, the Indenture Trustee with the approval of the 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 Book-Entry Notes to which it has a security entitlement in the manner prescribed in Section 4.08.

The Notes 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 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 Notes; Appointment of Certificate Registrar. The Issuer shall cause to be kept at the Indenture Trustee’s Corporate Trust Office a Note Register in which, subject to such reasonable regulations as it may prescribe, the Note Registrar shall provide for the registration of Notes and of transfers and exchanges of Notes as herein provided.

Each purchaser of a Note (other than a Class 1B-1, Class 1B-2 and SB Note), by its acceptance of the Note, shall be deemed to have represented that the acquisition of such Note by the purchaser does not constitute or give rise to a prohibited transaction under Section 406 of ERISA or Section 4975 of the Code, for which no statutory, regulatory or administrative exemption is available.

No transfer, sale, pledge or other disposition of a Class 1B-1, Class 1B-2 or Class SB Note shall be made unless such transfer, sale, pledge or other disposition is exempt from the registration requirements of the Securities Act of 1933, as amended (the “1933 Act”), and any applicable state securities laws or is made in accordance with said Act and laws. Except as otherwise provided in this Section 4.02, in the event that a transfer of a Class 1B-1, Class 1B-2 or Class SB Note is to be made, (i) unless the Depositor directs the Indenture Trustee otherwise, the Indenture Trustee shall require a written Opinion of Counsel acceptable to and in form and substance satisfactory to the Indenture Trustee, the Issuer and the Depositor that such transfer may be made pursuant to an exemption, describing the applicable exemption and the basis therefor, from said Act and laws or is being made pursuant to said Act and laws, which Opinion of Counsel shall not be an expense of the Indenture Trustee, the Trust Estate, the Depositor, the Issuer or the Servicer, and (ii) the Indenture Trustee shall require the transferee to execute a representation letter, substantially in the form of Exhibit D hereto, and the Indenture Trustee shall require the transferor to execute a representation letter, substantially in the form of Exhibit E hereto, each acceptable to and in form and substance satisfactory to the Depositor, the Issuer and the Indenture Trustee certifying to the Depositor, the Issuer and the Indenture Trustee the facts surrounding such transfer, which representation letters shall not be an expense of the Indenture Trustee, the Trust Estate, the Depositor, the Issuer or the Servicer. In lieu of the requirements set forth in the preceding sentence, transfers of Class 1B-1, Class 1B-2 or Class SB Notes may be made in accordance with this Section 4.02 if the prospective transferee of such a Certificate provides the Indenture Trustee, the Depositor and the Issuer with an investment letter substantially in the form of Exhibit F attached hereto, which investment letter shall not be an expense of the Indenture Trustee, the Issuer, the Trust Estate, the Depositor or the Servicer, and which investment letter states that, among other things, such transferee (i) is a “qualified institutional buyer” as defined under Rule 144A, acting for its own account or the accounts of other “qualified institutional buyers” as defined under Rule 144A, and (ii) is aware that the proposed transferor intends to rely on the exemption from registration requirements under the 1933 Act provided by Rule 144A. The Holder of a Class 1B-1, Class 1B-2 or Class SB Note desiring to effect any transfer, sale, pledge or other disposition shall, and does hereby agree to, indemnify the Indenture Trustee, the Depositor, the Servicer, the Issuer and the Note Registrar against any liability that may result if the transfer, sale, pledge or other disposition is not so exempt or is not made in accordance with such federal and state laws and this Indenture. In the case of any Class 1B-1, Class 1B-2 or Class SB Note presented for registration in the name of any Person, either (i) the Indenture Trustee shall require an Opinion of Counsel acceptable to and in form and substance satisfactory to the Indenture Trustee, the Depositor and the Issuer to the effect that the purchase or holding of such Class 1B-1, Class 1B-2 or Class SB Note is permissible under applicable law, will not constitute or result in any non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code (or comparable provisions of any subsequent enactments), and will not subject the Indenture Trustee, the Issuer, the Depositor or the Servicer to any obligation or liability (including obligations or liabilities under ERISA or Section 4975 of the Code) in addition to those undertaken in this Indenture or the Servicing Agreement, which Opinion of Counsel shall not be an expense of the Indenture Trustee, the Issuer, the Depositor or the Servicer, or (ii) the prospective transferee shall be required to provide the Indenture Trustee, the Depositor and the Servicer with a certification to the effect set forth in Exhibit F, which the Indenture Trustee may rely upon without further inquiry or investigation, in order to establish that such transferee or the Person in whose name

such registration is requested is not an employee benefit plan or other plan or arrangement subject to the prohibited transaction provisions of ERISA or Section 4975 of the Code, or any Person (including an insurance company investing its general accounts, an investment manager, a named fiduciary or a trustee of any such plan) who is using “plan assets” of any such plan to effect such acquisition (each of the foregoing, a “Plan Investor”).

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

Subject to the foregoing, at the option of the Noteholders, Notes may be exchanged for other Notes of the same Class and of like tenor, in authorized initial Note Balances evidencing the same aggregate Percentage Interests upon surrender of the Notes to be exchanged at the Corporate Trust Office of the Note Registrar. Whenever any Notes are so surrendered for exchange, the Indenture Trustee shall execute and the Note Registrar shall authenticate and deliver the Notes which the Noteholder making the exchange is entitled to receive. Each Note presented or surrendered for registration of transfer or exchange shall (if so required by the Note Registrar) be duly endorsed by, or be accompanied by a written instrument of transfer in form reasonably satisfactory to the Note Registrar duly executed by, the Holder thereof or such Holder’s attorney duly authorized in writing with such signature guaranteed by an “eligible guarantor institution” meeting the requirements of the Note Registrar, which requirements include membership or participation in the Securities Transfer Agent’s Medallion Program (“STAMP”) or such other “signature guarantee program” as may be determined by the Note Registrar in addition to, or in substitution for, STAMP, all in accordance with the Securities Exchange Act of 1934, as amended. Notes delivered upon any such transfer or exchange will evidence the same obligations, and will be entitled to the same rights and privileges, as the Notes surrendered.

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

All Notes surrendered for registration of transfer and exchange shall be canceled by the Note Registrar and delivered to the Indenture Trustee for subsequent destruction.

The Issuer hereby appoints the Indenture Trustee as Certificate Registrar to keep at its Corporate Trust Office a Certificate Register pursuant to Section 3.05 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 3.09 of the Trust Agreement. The Indenture Trustee hereby accepts such appointment.

Section 4.03. Mutilated, Destroyed, Lost or Stolen Notes. If (i) any mutilated Note is surrendered to the Indenture Trustee, or the Indenture Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Note, and (ii) in the case of a destroyed, lost or stolen note, 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 Note Registrar or the Indenture Trustee that such Note has been acquired by a protected 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 Note, a replacement Note of the same Class; provided, however, that if any such destroyed, lost or stolen Note, but not a mutilated Note, shall have become or within seven days shall be due and payable, instead of issuing a replacement Note, the Issuer may pay such destroyed, lost or stolen Note when so due or payable without surrender thereof. If, after the delivery of such replacement Note or payment of a destroyed, lost or stolen Note pursuant to the proviso to the preceding sentence, a protected purchaser of the original Note in lieu of which such replacement Note was issued presents for payment such original Note, the Issuer and the Indenture Trustee shall be entitled to recover such replacement Note (or such payment) from the Person to whom it was delivered or any Person taking such replacement Note from such Person to whom such replacement Note was delivered or any assignee of such Person, except a protected 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 Note under this Section 4.03, the Issuer may require the payment by the Holder of such Note of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other reasonable expenses (including the fees and expenses of the Indenture Trustee) connected therewith.

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

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

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

Section 4.05. Cancellation. All Notes surrendered for payment, registration of transfer, exchange or redemption shall, if surrendered to any Person other than the Indenture Trustee, be delivered to the Indenture Trustee and shall be promptly canceled by the Indenture Trustee. The Issuer may at any time deliver to the Indenture Trustee for cancellation any Notes previously authenticated and delivered hereunder which the Issuer may have acquired in any manner

whatsoever, and all Notes so delivered shall be promptly canceled by the Indenture Trustee. No Notes shall be authenticated in lieu of or in exchange for any Notes canceled as provided in this Section 4.05, except as expressly permitted by this Indenture. All canceled Notes may be held or disposed of by the Indenture Trustee in accordance with its standard retention or disposal policy as in effect at the time unless the 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 Notes have not been previously disposed of by the Indenture Trustee.

Section 4.06. Book-Entry Notes. The Notes, upon original issuance, will be issued in the form of typewritten Notes constituting the Book-Entry Notes, to be delivered to The Depository Trust Company, the initial Depository, by, or on behalf of, the Issuer. The Notes shall initially be registered on the Note Register in the name of Cede & Co., the nominee of the initial Depository, and no Beneficial Owner will receive a Definitive Note representing such Beneficial Owner’s security entitlement to such Book-Entry Note, except as provided in Section 4.08. Unless and until definitive, fully registered Notes (the “Definitive Notes”) have been issued to Beneficial Owners pursuant to Section 4.08:

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

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

(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 Beneficial Owners and the Depository and/or the Depository Participants. Unless and until Definitive Notes are issued pursuant to Section 4.08, the initial Depository will make book-entry transfers among the Depository Participants and receive and transmit payments of principal of and interest on the Notes to such Depository Participants; and

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

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

Section 4.08. Definitive Notes. If (i) the Issuer determines that the Depository is no longer willing or able to properly discharge its responsibilities with respect to the Notes and the Indenture Trustee is unable to locate a qualified successor, (ii) the Issuer elects to terminate the book-entry system through the Depository or (iii) after the occurrence of an Event of Default, Holders of the Notes representing security entitlements to at least a majority of the Note Balances of the Notes advise the Depository (with a copy to the Indenture Trustee) in writing that the continuation of a book-entry system through the Depository is no longer in the best interests of the Beneficial Owners, then the Depository shall notify all Beneficial Owners and the Indenture Trustee of the occurrence of any such event and of the availability of Definitive Notes to Beneficial Owners. Upon surrender to the Indenture Trustee of the typewritten Notes constituting the Book-Entry Notes by the Depository, accompanied by registration instructions, the Issuer shall execute and the Indenture Trustee shall authenticate the Definitive Notes in accordance with the instructions of the Depository. None of the Issuer, the Note Registrar or the Indenture Trustee shall be liable for any delay in delivery of such instructions and may conclusively rely on, and shall be protected in relying on, such instructions. Upon the issuance of Definitive Notes, the Indenture Trustee shall recognize the Holders of the Definitive Notes as Noteholders.

Section 4.09. Tax Treatment. The Issuer has entered into this Indenture, and the Notes will be issued, with the intention that, for federal, state and local income, single business and franchise tax purposes, the Notes will be treated as indebtedness for purposes of such taxes and in addition, for federal tax purposes, the Group 2 Notes will qualify as regular interests in a REMIC as defined in the Code. The Issuer, by entering into this Indenture, and each Noteholder, by its acceptance of its Note (and each Beneficial Owner by its acceptance of an interest in the applicable Book-Entry Note), agree to treat the Notes for federal, state and local income, single business and franchise tax purposes as indebtedness for purposes of such taxes and in addition, for the Group 2 Notes, as regular interests in a REMIC as defined in the Code.

Section 4.10. Satisfaction and Discharge of Indenture. This Indenture shall cease to be of further effect with respect to the Notes except as to (i) rights of registration of transfer and exchange, (ii) substitution of mutilated, destroyed, lost or stolen Notes, (iii) rights of Noteholders to receive payments of principal thereof and interest thereon, (iv) Sections 3.03, 3.04, 3.06, 3.09, 3.13, 3.15, 3.16 and the last paragraph of Section 4.02, (v) the rights, obligations and immunities of the Indenture Trustee hereunder (including the rights of the Indenture Trustee under Section 6.07 and the obligations of the Indenture Trustee under Section 4.11) and (vi) the rights of Noteholders as beneficiaries hereof with respect to the property so deposited with the Indenture Trustee payable to all or any of them, and the Indenture Trustee, on demand of and at the expense of the Issuer, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture with respect to the Notes, when:

(A) either

(1) each Class of Notes theretofore authenticated and delivered (other than (i) Notes that have been destroyed, lost or stolen and that have been replaced or paid as provided in Section 4.03 and (ii) Notes for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Issuer and thereafter repaid to the

Issuer or discharged from such trust, as provided in Section 3.03) have been delivered to the Indenture Trustee for cancellation; or

(2) each Class of Notes not theretofore delivered to the Indenture Trustee for cancellation:

a.	have become due and payable,
b.	will become due and payable within one year, or
c.	have been declared immediately due and payable pursuant to Section 5.02.

and the Issuer, in the case of a. or b. above, has irrevocably deposited or caused to be irrevocably deposited with the Indenture Trustee cash or direct obligations of or obligations guaranteed by the United States of America (which will mature prior to the date such amounts are payable), in trust for such purpose, in an amount sufficient to pay and discharge the entire indebtedness on such Notes then outstanding not theretofore delivered to the Indenture Trustee for cancellation when due on the Final Scheduled Payment Date;

(B) the Issuer has paid or caused to be paid all other sums payable hereunder by the Issuer (including amounts payable to the Indenture Trustee); and

(C) the Issuer has delivered to the Indenture Trustee an Officer’s Certificate and an Opinion of Counsel, each meeting the applicable requirements of Section 10.01, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have been complied with and, if the Opinion of Counsel relates to a deposit made in connection with Section 4.10(A)(2)b. above, such opinion shall further be to the effect that such deposit will not have any material adverse tax consequences to the Issuer, any Noteholders or any Certificateholders.

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 Notes and this Indenture, to the payment, either directly or through any Paying Agent or Certificate Paying Agent, as the Indenture Trustee may determine, to the Securityholders, of all sums due and to become due thereon for principal and interest; 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 Notes, all monies then held by any Person other than the Indenture Trustee under the provisions of this Indenture with respect to such Notes 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 Paying Agent shall be released from all further liability with respect to such monies.

Section 4.13. Temporary Notes. Pending the preparation of any Definitive Notes, the Issuer may execute and upon its written direction, the Indenture Trustee may authenticate and make available for delivery, temporary Notes that are printed, lithographed, typewritten, photocopied or otherwise produced, in any denomination, substantially of the tenor of the Definitive Notes in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Notes may determine, as evidenced by their execution of such Notes.

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

ARTICLE V

DEFAULT AND REMEDIES

Section 5.01. Events of Default. The Issuer shall deliver to the Indenture Trustee, within five days after learning of the occurrence any event which with the giving of notice and the lapse of time would become an Event of Default under clause (iii) of the definition of “Event of Default” written notice in the form of an Officer’s Certificate of its status and what action the Issuer is taking or proposes to take with respect thereto.

Section 5.02. Acceleration of Maturity; Rescission and Annulment. If an Event of Default should occur and be continuing, then and in every such case the Indenture Trustee may, and upon the request of the Holders of Notes representing not less than a majority of the Voting Rights of all Notes, the Indenture Trustee shall, declare the Notes to be immediately due and payable, by a notice in writing to the Issuer (and to the Indenture Trustee if given by Noteholders), and upon any such declaration the unpaid principal amount of each Class of Notes, together with accrued and unpaid interest thereon through the date of acceleration, shall become immediately due and payable.

At any time after such declaration of acceleration of maturity with respect to an Event of Default has been made and before a judgment or decree for payment of the money due has been obtained by the Indenture Trustee as hereinafter in this Article V provided, the Holders of Notes representing a majority of the Voting Rights of all Notes, by written notice to the Issuer and the Indenture Trustee may in writing 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 Notes and all other amounts that would then be due hereunder or upon the Notes if the Event of Default giving rise to such acceleration had not occurred; and

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

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

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

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

(a) The Issuer covenants that if a default occurs in the payment of (i) any interest on any Note when the same becomes due and payable, and such default continues for a period of five days, or (ii) the principal of or any installment of the principal of any Note when the same becomes due and payable, the Issuer shall, upon demand of the Indenture Trustee, pay to it, for the benefit of the Noteholders, the whole amount then due and payable on the Notes for principal and interest, with interest upon the overdue principal, and in addition thereto such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses and disbursements 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 10.17 hereof may institute a Proceeding for the collection of the sums so due and unpaid, and may prosecute such Proceeding to judgment or final decree, and may enforce the same against the Issuer or other obligor upon the Notes and collect in the manner provided by law out of the property of the Issuer or other obligor upon the Notes, wherever situated, the monies adjudged or decreed to be payable.

(c) If an Event of Default occurs and is continuing, the Indenture Trustee subject to the provisions of Section 10.17 hereof may, as more particularly provided in Section 5.04, in its discretion, proceed to protect and enforce its rights and the rights of the Noteholders, by such appropriate Proceedings as the Indenture Trustee shall deem most effective to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy or legal or equitable right vested in the Indenture Trustee by this Indenture or by law.

(d) In case there shall be pending, relative to the Issuer or any other obligor upon the Notes or any Person having or claiming an ownership interest in the Trust Estate, Proceedings under Title 11 of the United States Code or any other applicable federal or state bankruptcy, insolvency or other similar law, or in case a receiver, assignee or trustee in bankruptcy or

reorganization, liquidator, sequestrator or similar official shall have been appointed for or taken possession of the 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 Notes, or to the creditors or property of the Issuer or such other obligor, the Indenture Trustee, irrespective of whether the principal of any Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Indenture Trustee shall have made any demand pursuant to the provisions of this Section, shall be entitled and empowered, by intervention in such Proceedings or otherwise:

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

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

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

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

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

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

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

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

Section 5.04. Remedies; Priorities.

(a) If an Event of Default shall have occurred and be continuing, the Indenture Trustee subject to the provisions of Section 10.17 hereof may do one or more of the following (subject to Section 5.05):

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

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

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

(iv) refrain from selling the Trust Estate (unless otherwise directed by a majority of Noteholders) and continue to apply all amounts received thereon to payments on the Notes in accordance with Section 3.05; and

(v) 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 must sell or otherwise liquidate the Trust Estate following an Event of Default, if (i) the Holders of the Notes representing not less than a majority of the Voting Rights of all of the Notes direct the Indenture Trustee to sell or otherwise liquidate the Trust Estate or (ii) the Indenture Trustee determines that the Loans will not continue to provide sufficient funds for (A) the payment of expenses under this Indenture and (B) the payment of principal of and interest on the Notes as they would have become due if the Notes had not been declared due and payable. In determining such sufficiency or insufficiency with respect to clause (A) and (B), the Indenture Trustee may, but need not, obtain and rely upon an opinion of an Independent investment banking or accounting firm of national reputation as to the feasibility of such proposed action and as to the sufficiency of the Trust Estate for such purpose.

Notwithstanding the foregoing, so long as a Servicing Default has not occurred, any Sale of the Trust Estate shall be made subject to the continued servicing of the Loans by the Servicer as provided in the Servicing Agreement.

Section 5.05. Optional Preservation of the Trust Estate. If the Notes have been declared to be due and payable under Section 5.02 following an Event of Default and such declaration and its consequences have not been rescinded and annulled, the Indenture Trustee shall, unless otherwise directed to by a majority of the Voting Rights of the Notes, elect to take and maintain possession of the Trust Estate. It is the desire of the parties hereto and the Noteholders that there be at all times sufficient funds for the payment of principal of and interest on the Notes and other obligations of the Issuer.

Section 5.06. Limitation of Suits. No Noteholder shall have any right to institute any Proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless and subject to the provisions of Section 10.17 hereof:

(i) such Noteholder 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 Voting Rights of the Notes have made written request to the Indenture Trustee to institute such Proceeding in respect of such Event of Default in its own name as Indenture Trustee hereunder;

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

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

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

It is understood and intended that no one or more Noteholders 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 Noteholder or to obtain or to seek to obtain priority or preference over any other Noteholder or to enforce any right under this Indenture, except in the manner herein provided.

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

Section 5.07. Unconditional Rights of Noteholders to Receive Principal and Interest. Notwithstanding any other provisions in this Indenture each Noteholders shall have the right, which is absolute and unconditional, to receive payment of the principal of, and interest, on such Note on or after the respective due dates thereof expressed in such Note or in this Indenture and

to institute suit for the enforcement of any such payment, and such right shall not be impaired without the consent of such Holder.

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

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

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

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

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

(ii) subject to the express terms of Section 5.04, any direction to the Indenture Trustee to sell or liquidate the Trust Estate shall be by Holders of Notes representing not less than a majority of the Voting Rights of Notes;

(iii) if the conditions set forth in Section 5.05 have been satisfied and the Indenture Trustee is required to retain the Trust Estate pursuant to such Section, then any direction to the Indenture Trustee by Holders of Notes representing less than a majority of the Voting Rights of Notes to sell or liquidate the Trust Estate shall be of no force and effect; and

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

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

Section 5.12. Waiver of Past Defaults. Prior to the declaration of the acceleration of the maturity of the Notes as provided in Section 5.02, the Holders of Notes of not less than a majority of the Voting Rights of the Notes may waive any past Event of Default and its consequences except an Event of Default (a) with respect to payment of principal of or interest on any of the Notes or (b) in respect of a covenant or provision hereof which cannot be modified or amended without the consent of each Noteholder. In the case of any such waiver, the Issuer, the Indenture Trustee and the Noteholders 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 Noteholder by such Noteholder’s acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Indenture Trustee for any action taken, suffered or omitted by it as Indenture Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section 5.13 shall not apply to (a) any suit instituted by the Indenture Trustee, (b) any suit instituted by any Noteholder, or group of Noteholders, in each case holding in the aggregate more than 10% of the Voting Rights of the Notes or (c) any suit instituted by any Noteholder for the enforcement of the payment of principal of or interest on any Note on or after the respective due dates expressed in such Note and in this Indenture.

Section 5.14. Waiver of Stay or Extension Laws. The 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 is expressly subject to the provisions of Section 5.05 and this Section 5.15. The power to effect any such Sale shall not be exhausted by any one or more Sales as to any portion of the Trust Estate remaining unsold, but shall continue unimpaired until

the entire Trust Estate shall have been sold or all amounts payable on the Notes and under this Indenture 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) all Noteholders consent to or direct the Indenture Trustee to make, such Sale, or

(2) the proceeds of such Sale would be not less than the entire amount which would be payable to the Noteholders under the Notes and the Certificateholder under the Certificate, in full payment thereof in accordance with Section 5.02, on the Payment Date next succeeding the date of 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 Securityholders have otherwise consented or directed the Indenture Trustee, the Indenture Trustee will not sell at any public Sale 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.

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

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

(2) the Indenture Trustee may bid for and acquire the property offered for Sale in connection with any Sale thereof, and, subject to any requirements of, and to the extent permitted by, applicable law in connection therewith, may purchase all or any portion of the Trust Estate in a private sale, and, in lieu of paying cash therefor, may make settlement for the purchase price by crediting the gross Sale price against the sum of (A) the amount which would be distributable to the Securityholders as a result of such Sale in accordance with Section 5.04(b) on the Payment Date next succeeding the date of such Sale and (B) the expenses of the Sale and of any Proceedings in connection therewith which are reimbursable to it, without being required to produce the Notes in order to complete any such Sale or in order for the net Sale price to be credited against such Notes, and any property so acquired by the Indenture Trustee shall be held and dealt with by it in accordance with the provisions of this Indenture;

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

(4) the Indenture Trustee is hereby irrevocably appointed the agent and attorney-in-fact of the 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

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

Section 5.16. Action on Notes. The Indenture Trustee’s right to seek and recover judgment on the Notes or under this Indenture shall not be affected by the seeking, obtaining or application of any other relief under or with respect to this Indenture. Neither the lien of this Indenture nor any rights or remedies of the Indenture Trustee or the Noteholders shall be impaired by the recovery of any judgment by the Indenture Trustee against the 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).

ARTICLE VI

THE INDENTURE TRUSTEE

Section 6.01. Duties of Indenture Trustee.

(a) If an Event of Default has occurred and is continuing, the Indenture Trustee shall exercise the rights and powers vested in it by this Indenture and use the same degree of care and skill in their exercise as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs.

(b)	Except during the continuance of an Event of Default:

(i) the Indenture Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture and no implied covenants or obligations shall be read into this Indenture against the Indenture Trustee; and

(ii) in the absence of bad faith on its part, the Indenture Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Indenture Trustee and conforming to the requirements of this Indenture; however, the Indenture Trustee shall examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture.

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

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

(ii) the Indenture Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer unless it is proved that the Indenture Trustee was negligent in ascertaining the pertinent facts; and

(iii) the Indenture Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 5.11 which it is entitled to receive under any of the Basic Documents.

(e) Money held in trust by the Indenture Trustee need not be segregated from other funds except to the extent required by law or the terms of this Indenture or the Trust Agreement.

(f) No provision of this Indenture shall require the Indenture Trustee to expend or risk its own funds or otherwise incur financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers, if it shall have reasonable grounds to

believe that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

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

(h) The Indenture Trustee hereby accepts appointment as Certificate Paying Agent under the Trust Agreement and agrees to be bound by the provisions of the Trust Agreement relating to the Certificate Paying Agent.

Section 6.02. Rights of Indenture Trustee.

(a) The Indenture Trustee may rely on any document believed by it to be genuine and to have been signed or presented by the proper person. The Indenture Trustee need not investigate any fact or matter stated in the document.

(b) Before the Indenture Trustee acts or refrains from acting, it may require an Officer’s Certificate or an Opinion of Counsel. The Indenture Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on an Officer’s Certificate or Opinion of Counsel.

(d) The Indenture Trustee shall not be liable for any action it takes or omits to take in good faith which it believes to be authorized or within its rights or powers; provided, however, that the Indenture Trustee’s conduct does not constitute willful misconduct, negligence or bad faith.

(e) The Indenture Trustee may consult with counsel, and the advice or opinion of counsel with respect to legal matters relating to this Indenture and the Notes shall be full and complete authorization and protection from liability in respect to any action taken, omitted or suffered by it hereunder in good faith and in accordance with the advice or opinion of such counsel.

Section 6.03. Individual Rights of Indenture Trustee. The Indenture Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuer or its Affiliates with the same rights it would have if it were not Indenture Trustee. Any Note 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.

Section 6.04. Indenture Trustee’s Disclaimer. The Indenture Trustee shall not be (i) responsible for and makes no representation as to the validity or adequacy of this Indenture, the Trust Agreement or the Notes, (ii) accountable for the Issuer’s use of the proceeds from the

Notes or (iii) responsible for any statement of the Issuer or any other Person in the Indenture, the Trust Agreement or in any document issued in connection with the sale of the Notes or in the Notes other than the Indenture Trustee’s certificate of authentication.

Section 6.05. Notice of Event of Default. The Indenture Trustee shall mail to each Noteholder notice of an Event of Default of which a Responsible Officer of the Indenture Trustee has actual knowledge within the later of 90 days after it occurs and 90 days after such Responsible Officer’s knowledge thereof. Except in the case of an Event of Default in payment of principal of or interest on any Note, the Indenture Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of Noteholders.

Section 6.06. Reports by Indenture Trustee to Holders. The Indenture Trustee shall deliver to each Noteholder such information with respect to the Notes as may be required to enable such holder to prepare its federal and state income tax returns including without limitation Form 1099, to the extent such form is required by law. In addition, upon the Issuer’s written request, the Indenture Trustee shall promptly furnish information reasonably requested by the Issuer with respect to the Notes that is reasonably available to the Indenture Trustee to enable the Issuer to perform its federal and state income tax reporting obligations.

Section 6.07. Compensation and Indemnity. The Indenture Trustee, as compensation for its activities hereunder, shall be entitled to withdraw from the Payment Account on each Payment Date prior to making distributions pursuant to Section 3.05 the Trustee Fee for such Payment Date. The Indenture Trustee shall be indemnified by the Seller in accordance with Section 4(b) of the Administration Agreement, and all amounts owing to the Indenture Trustee hereunder in excess of such amount shall be paid solely as provided in Section 3.05 hereof (subject to the priorities set forth therein). 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 Trustee Additional Expenses, in addition to the compensation for its services. 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 reasonable 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. 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. No termination of the Indenture Trustee without cause will be effective unless the costs and expenses of such Indenture Trustee have been reimbursed to the Indenture Trustee in connection with such removal. The Indenture Trustee may resign at any time by so notifying the Issuer. The Holders of a majority of Note Balances of the Notes 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;
(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. In addition, the Indenture Trustee will resign to avoid being directly or indirectly controlled by the Issuer.

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.

Such Form 10-K shall include as exhibits, the annual statement of compliance described under Section 3.10 of the Servicing Agreement and the annual servicing report described under Section 3.11 of the Servicing Agreement, to the extent such reports have been timely delivered to the Indenture Trustee. If they are not so timely delivered, the Indenture Trustee shall file an amended Form 10-K including such documents as exhibits promptly after they are delivered to the Indenture Trustee. The Indenture Trustee shall have no liability with respect to (a) any failure to properly or timely prepare or file such periodic reports resulting from or relating to the Indenture Trustee’s inability or failure to obtain any information not resulting from its own negligence, willful misconduct or bad faith, or (b) any inaccuracy in such periodic reports resulting from incorrect information provided to the Indenture Trustee by the Servicer. The Form 10-K shall also include a certification in the form attached hereto as Exhibit B (the “Depositor Certification”), which shall be signed by the senior officer of the Depositor in charge of securitization and furnished to the Indenture Trustee at least 5 Business Days prior to the date on which the Form 10-K is required to be filed.

If the indemnification provided for herein is unavailable or insufficient to hold harmless such Persons, then the Indenture Trustee shall contribute to the amount paid or payable by such Persons as a result of the losses, claims, damages or liabilities of such Persons in such proportion as is appropriate to reflect the relative fault of the Depositor on the one hand and the Indenture Trustee on the other. The Indenture Trustee acknowledges that the Depositor is relying on the Indenture Trustee’s performance of its

obligations under this Section 6.16 in order to perform its obligations under Section 6.16(b) above.

(d) If the Commission issues additional interpretative guidance or promulgates additional rules or regulations, or if other changes in applicable law occur, that would require the reporting arrangements, or the allocation of responsibilities with respect thereto, described in this Section 6.16, to be conducted differently than as described, the Depositor and the Indenture Trustee will reasonably cooperate to amend the provisions of this Section 6.16 in order to comply with such amended reporting requirements and such amendment of this Section 6.16. Any such amendment shall be made in accordance with Section 9.01 without the consent of the Certificateholders, and may result in a change in the reports filed by the Indenture Trustee on behalf of the Issuer under the Exchange Act. Notwithstanding the foregoing, the Depositor and the Indenture Trustee shall not be obligated to enter into any amendment pursuant to this Section 6.12 that adversely affects its obligations and immunities under this Indenture.

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

(b) (i) Prior to the deposit of any Collateral or other property or securities with the Indenture Trustee that is to be made the basis for the release of any property or securities subject to the lien of this Indenture, the 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 of such deposit) to the Issuer of the Collateral or other property or securities to be so deposited.

(ii) Whenever the Issuer is required to furnish to the Indenture Trustee an Officer’s Certificate certifying or stating the opinion of any signatory thereof as to the matters described in clause (i) above, the Issuer shall also deliver to the Indenture Trustee an Independent Certificate as to the same matters, if the fair value to the Issuer 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 Note Balances of the Notes, but such a certificate need not be furnished with respect to any securities so deposited, if the fair value thereof to the Issuer as set forth in the related Officer’s Certificate is less than $25,000 or less than one percent of the Note Balances of the Notes.

(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 of such release) of the property or securities proposed to be released and stating that in the opinion of such person the proposed release will not impair the security under this Indenture in contravention of the provisions hereof.

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

permitted or required by the Basic Documents, so long as the Issuer shall deliver to the Indenture Trustee every six months, commencing January 1, 2006, an Officer’s Certificate of the Issuer stating that all the dispositions of Collateral described in clauses (A) or (B) above that occurred during the preceding six calendar months were in the ordinary course of the Issuer’s business and that the proceeds thereof were applied in accordance with the Basic Documents.

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

Any certificate or opinion of an Authorized Officer of the 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 such officer’s 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, the Depositor or the Issuer, stating that the information with respect to such factual matters is in the possession of the Seller, the Depositor 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 Noteholders.

(a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Noteholders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Noteholders in person or by agents duly appointed in writing; and except as herein otherwise expressly provided such action shall become effective when such instrument or instruments are delivered to the Indenture Trustee, and, where it is hereby expressly required, to the Issuer. Such

instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act of Noteholders” signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and (subject to Section 6.01) conclusive in favor of the Indenture Trustee and the Issuer, if made in the manner provided in this Section 10.03.

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

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

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

Section 10.04.

Notices, etc., to Indenture Trustee, Issuer and Rating Agencies.

(a) Any request, demand, authorization, direction, notice, consent, waiver or Act of Noteholders or other documents provided or permitted by this Indenture shall be in writing and if such request, demand, authorization, direction, notice, consent, waiver or Act of Noteholders is to be made upon, given or furnished to or filed with:

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

(ii) the Issuer by the Indenture Trustee or by any Noteholder, it shall be sufficient for every purpose hereunder if in writing and mailed first-class, postage prepaid to the Issuer addressed to: Irwin Whole Loan Home Equity Trust 2005-B, in care of the Owner Trustee, as set forth in the Trust Agreement, 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 Noteholders to the Indenture Trustee.

Notices required to be given to the Rating Agencies by the Issuer or the Indenture Trustee shall be in writing, personally delivered or mailed by certified mail, return receipt requested, to (i) in the case of Moody’s, at the following address: Moody’s Investors Service, Inc., ABS Monitoring Department, 99 Church Street, New York, New York 10007, Attention: Residential Mortgage Surveillance Group and (ii) in the case of Standard & Poor’s, at the following address: Standard & Poor’s, 26 Broadway, 15th Floor, New York, New York 10004, Attention: Asset Backed Surveillance Department; or as to each of the foregoing, at such other address as shall be designated by written notice to the other parties.

Section 10.05. Notices to Noteholders; Waiver. Where this Indenture provides for notice to Noteholders of any event, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class, postage prepaid to each Noteholder

affected by such event, at such Person’s address as it appears on the Note Register, not later than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice. In any case where notice to Noteholders is given by mail, neither the failure to mail such notice nor any defect in any notice so mailed to any particular Noteholder shall affect the sufficiency of such notice with respect to other Noteholders, and any notice that is mailed in the manner herein provided shall conclusively be presumed to have been duly given regardless of whether such notice is in fact actually received.

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

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

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

Section 10.06. Alternate Payment and Notice Provisions. Notwithstanding any provision of this Indenture or any of the Notes to the contrary, the Issuer may enter into any agreement with any Noteholder providing for a method of payment, or notice by the Indenture Trustee to such Noteholder, that is different from the methods provided for in this Indenture for such payments or notices. The Issuer shall furnish to the Indenture Trustee a copy of each such agreement and the Indenture Trustee shall cause payments to be made and notices to be given in accordance with such agreements.

Section 10.07. Conflict with Trust Indenture Act. If any provision hereof limits, qualifies or conflicts with another provision hereof that is required to be included in this Indenture by any of the provisions of the Trust Indenture Act, such required provision shall control.

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

Section 10.09. Successors and Assigns. All covenants and agreements in this Indenture and the Notes by the 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 10.10. Separability. In case any provision in this Indenture or in the Notes shall be invalid, illegal or unenforceable, the validity, legality, and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

Section 10.11. Benefits of Indenture. Nothing in this Indenture or in the Notes, express or implied, shall give to any Person, other than the parties hereto and their successors hereunder, and the Noteholders and any other party secured hereunder, and any other Person with an ownership interest in any part of the Trust Estate, any benefit or any legal or equitable right, remedy or claim under this Indenture.

Section 10.12. Legal Holidays. In any case where the date on which any payment is due shall not be a Business Day, then (notwithstanding any other provision of the Notes or this Indenture) payment need not be made on such date, but may be made on the next succeeding Business Day with the same force and effect as if made on the date on which nominally due, and no interest shall accrue for the period from and after any such nominal date.

Section 10.13. GOVERNING LAW. THIS INDENTURE SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REFERENCE TO ITS CONFLICT OF LAW PROVISIONS, AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

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

Section 10.15. Recording of Indenture. If this Indenture is subject to recording in any appropriate public recording offices, such recording is to be effected by the Issuer and at its expense accompanied by an Opinion of Counsel (which may be counsel to the Indenture Trustee or any other counsel reasonably acceptable to the Indenture Trustee) to the effect that such recording is necessary either for the protection of the Noteholders or any other Person secured hereunder or for the enforcement of any right or remedy granted to the Indenture Trustee under this Indenture.

Section 10.16. 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 Notes or under this Indenture or any certificate or other writing delivered in connection herewith or therewith, against (i) the Indenture Trustee or the Owner Trustee in its individual capacity, (ii) any owner of a beneficial interest in the 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). 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 10.17. No Petition. The Indenture Trustee, by entering into this Indenture, and each Noteholder, by accepting a Note, hereby covenant and agree that they will not at any time prior to the day one year and one day after the date this Indenture terminates 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 Notes, this Indenture or any of the Basic Documents.

Section 10.18. Optional Termination.

(a) The Holders of a majority of the Class CE-2 Certificates shall have the right, but not the obligation, to purchase from the Issuer all of the assets of the Trust Estate relating to the Group 1 Notes at a price equal to the Group 1 Termination Price on or after the first Payment Date on which an Group 1 Optional Termination is permitted and the right, but not the obligation, to purchase from the Issuer all of the assets of the Trust Estate relating to the Group 2 Notes at a price equal to the Group 2 Termination Price on or after the first Payment Date on which an Group 2 Optional Termination is permitted, in each case, as described in Section 10.18(c) below.

(b) If the Holders of a majority of the Class CE-2 Certificates do not exercise their option pursuant to Section 10.18(a) above on any Payment Date on which an Group 1 Optional Termination or Group 2 Optional Termination, as applicable, is permitted as described in Section 10.18(c) below, then the Servicer shall have the right, but not the obligation, to purchase from the Issuer all of the assets of the Trust Estate relating to the Group 1 Notes or the Group 2 Notes, as applicable, at a price equal to the Group 1 Termination Price or Group 2 Termination Price, as applicable; provided, however that the Servicer shall not be allowed to exercise such option unless the Group 1 Termination Price or Group 2 Termination Price, as applicable equals or exceeds the sum of (a) the aggregate Class Principal Balance of the Group 1 Notes or Group 2 Notes, as applicable, immediately prior to the Payment Date on which such purchase occurs, (b) the aggregate of any Group 1 Applied Loss Amounts on the Group 1 Notes or Group 2 Applied Loss Amounts on the Group 2 Notes, in each case, remaining unpaid immediately prior to the Payment Date on which such purchase occurs, (c) the aggregate of the Current Interest on the Group 1 Notes or Group 2 Notes, as applicable, for the Payment Date on which such purchase occurs, (d) the aggregate of any Carryforward Interest on the Group 1 Notes or Group 2 Notes, as applicable, for the Payment Date on which such purchase occurs and (e) any unpaid amounts owed to the Indenture Trustee or the Owner Trustee.

(c) The right of the Holders of a majority of the Class CE-2 Certificates or the Servicer, as applicable, to purchase the assets of the Issuer related to the Group 1 Notes or the Group 2 Notes, as applicable, pursuant to Section 10.18(a) or (b) above on any Payment Date is conditioned upon the Aggregate Loan Balance (after applying payments received in the related Collection Period) for the related Loan Group as of such Payment Date being less than ten percent of the Aggregate Loan Balance for such Loan Group as of the Cut-off Date. If such right is exercised, the Holders of a majority of the Class CE-2 Certificates or the Servicer, as applicable, shall deposit the applicable Group 1 Termination Price or Group 2 Termination Price, as applicable, with the Indenture Trustee pursuant to Section 4.10 hereof and, upon the receipt of such deposit, the Indenture Trustee or Custodian shall release to the designee appointed by the

Holders of a majority of the Class CE-2 Certificates or the Servicer, as applicable, the files pertaining to the Loans being purchased. The Holders of a majority of the Class CE-2 Certificates or the Servicer, as applicable, at their expense, shall prepare and deliver to the Indenture Trustee for execution, at the time the related Loans are to be released to the Holders of a majority of the Class CE-2 Certificates or the Servicer, as applicable, appropriate documents assigning each such Loan from the Indenture Trustee and the Issuer to the Holders of a majority of the Class CE-2 Certificates or the Servicer, as applicable. If the Group 1 Termination Price or Group 2 Termination Price, as applicable, is pursuant to Section 10.18(a) above, the Holders of a majority of the Class CE-2 Certificates shall give the Indenture Trustee and the Servicer not less than fifteen Business Days’ prior written notice of the Payment Date on which the Holders of a majority of the Class CE-2 Certificates anticipates that the final distribution will be made to the related Securityholders. If the Holders of a majority of the Class CE-2 Certificates do not give such notice with respect to any Payment Date, then if the Servicer exercises its Group 1 Termination Price or Group 2 Termination Price, as applicable, pursuant to Section 10.18(b) above, the Servicer shall give the Indenture Trustee no more than fourteen and not less than seven Business Days’ prior written notice of the Payment Date on which the Servicer anticipates that the final distribution will be made to the related Securityholders. Notice of any termination, specifying the anticipated Final Scheduled Payment Date or other Payment Date (which shall be a date that would otherwise be a Payment Date) upon which the Noteholders may surrender their Notes and/or the Certificateholders may surrender their Certificates to the Indenture Trustee (if so required by the terms hereof) for payment of the final distribution and cancellation, shall be given promptly by the Indenture Trustee specifying: (i) the anticipated Final Scheduled Payment Date or other Payment Date upon which final payment of the Notes and/or Certificates is anticipated to be made upon presentation and surrender of Notes and/or Certificates at the office or agency of the Indenture Trustee therein designated; and (ii) the amount of any such final payment, if known. Notwithstanding the foregoing, none of the Depositor, the Seller or any Affiliate of either the Depositor or the Seller shall have any right to purchase from the Issuer all of the assets of the Trust Estate pursuant to this Section, regardless of such entity’s ownership of the Certificates.

Section 10.19. Inspection. The Issuer agrees that, 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 and shall cause its representatives to hold in confidence all such information except to the extent disclosure may be required by law (and all reasonable applications for confidential treatment are unavailing) and except to the extent that the Indenture Trustee may reasonably determine that such disclosure is consistent with its obligations hereunder.

Section 10.20. Limitation of Liability of Owner Trustee. Notwithstanding anything to the contrary herein, this Indenture has been executed and delivered by Wilmington Trust Company, not individually or personally, but solely as Owner Trustee of Irwin Whole Loan Home Equity Trust 2005-B, in the exercise of the powers and authority conferred and vested in it, (a) each of the representations, undertakings and agreements herein made on the part of the Issuer is made

and intended not as personal representations, undertakings and agreements by Wilmington Trust Company, but is made and intended for the purpose for binding only the Issuer, (b) nothing herein contained shall be construed as creating any liability on Wilmington Trust Company, individually or personally, to perform any covenant either expressed or implied contained herein, all such liability, if any, being expressly waived by the parties hereto and by any Person claiming by, through or under the parties hereto and (c) under no circumstances shall Wilmington Trust Company be personally liable for the payment of any indebtedness or expenses of the Issuer or be liable for the breach or failure of any obligation, representation, warranty or covenant made or undertaken by the Issuer under this Indenture or any other related documents.

ARTICLE XI

REMIC PROVISIONS

Section 11.01. REMIC Provisions.

(a) The REMIC Administrator shall make an election to treat the Loans in Loan Group 2 and the proceeds of the Loans in Loan Group 2 and the proceeds on deposit in the Payment Account as two REMICs under the Code and, if necessary, under applicable state law, in accordance with Section 2.06 of the Trust Agreement, designated as REMIC I and REMIC II. Such election will be made on Form 1066 or other appropriate federal tax or information return (including Form 8811) or any appropriate state return for the taxable year ending on the last day of the calendar year in which the Securities are issued. For the purposes of the REMIC elections in respect of that portion of the Trust Estate, the REMIC I Regular Interests will be designated as the “regular interests” and Component I of the Class 2A-R Certificates will be the sole class of “residual interests” in REMIC I. For the purposes of the REMIC elections in respect of that portion of the Trust Estate, the REMIC II Regular Interests will be designated as the “regular interests” and Component II of the Class 2A-R Certificates will be the sole class of “residual interests” in REMIC II. The REMIC Administrator and the Trustee shall not permit the creation of any “interests” (within the meaning of Section 860G of the Code) in each REMIC elected in respect of the Trust Fund other than the “regular interests” and “residual interests” so designated.

(b) The Closing Date is hereby designated as the “Startup Day” of each of REMIC I and REMIC II, as designated in clause (a) above, within the meaning of Section 860G(a)(9) of the Code.

(c) The Indenture Trustee shall act on behalf of the “tax matters person” (within the meaning of the REMIC Provisions) for each REMIC created hereunder, in the manner provided under Treasury regulations section 1.860F 4(d) and temporary Treasury regulations section 301.6231(a)(7)1T.

(d) The REMIC Administrator shall (i) prepare, sign and file, or cause to be prepared, signed and filed, federal and state tax returns using a calendar year as the taxable year for each REMIC created hereunder when and as required by the REMIC Provisions and other applicable federal income tax laws as the direct representative of each such REMIC in compliance with the Code and shall provide copies of such returns as required by the Code; (ii) make an election, on behalf of each REMIC created hereunder, to be treated as a REMIC on the federal tax return of

such REMIC for its first taxable year, in accordance with the REMIC Provisions; and (iii) prepare and forward, or cause to be prepared and forwarded, to the Noteholders and to any governmental taxing authority all information reports as and when required to be provided to them in accordance with the REMIC Provisions and, otherwise, shall, shall deliver such tax returns in a timely manner to the Owner Trustee, if the Owner Trustee is required to sign such returns in accordance with Section 5.03 of the Trust Agreement, and shall sign (if the Owner Trustee is not so required) and file such tax returns in a timely manner. The expenses of preparing such returns shall be borne by the REMIC Administrator without any right of reimbursement therefor. The REMIC Administrator agrees to indemnify and hold harmless the Owner Trustee with respect to any tax or liability arising from the Owner Trustee’s signing of

Tax Returns that contain errors or omissions. The Servicer shall promptly provide the REMIC Administrator with such information as the REMIC Administrator may from time to time request for the purpose of enabling the REMIC Administrator to prepare Tax Returns.

(e) The REMIC Administrator shall provide (i) to any Transferor of a Class 2A-R Certificate such information as is necessary for the application of any tax relating to the transfer of a Class 2A-R Certificate to any Person who is not a Permitted Transferee, (ii) to the Indenture Trustee, and the Indenture Trustee shall forward to the Noteholders and the Certificateholders, such information or reports as are required by the Code or the REMIC Provisions including reports relating to interest, original issue discount and market discount or premium (using the Prepayment Assumption) and (iii) to the Internal Revenue Service the name, title, address and telephone number of the person who will serve as the representative of each REMIC.

(f) The Servicer and the REMIC Administrator shall take such actions and shall cause each REMIC created hereunder to take such actions as are reasonably within the Servicer’s or the REMIC Administrator’s control and the scope of its duties more specifically set forth herein as shall be necessary or desirable to maintain the status of each REMIC as a REMIC under the REMIC Provisions (and the Indenture Trustee shall assist the Servicer and the REMIC Administrator, to the extent reasonably requested by the Servicer and the REMIC Administrator to do so). The Servicer and the REMIC Administrator shall not knowingly or intentionally take any action, cause the Trust Estate to take any action or fail to take (or fail to cause to be taken) any action reasonably within their respective control that, under the REMIC Provisions, if taken or not taken, as the case may be, could (i) endanger the status of any portion of any of the REMICs as a REMIC or (ii) result in the imposition of a tax upon any of the REMICs (including but not limited to the tax on prohibited transactions as defined in Section 860F(a)(2) of the Code and the tax on contributions to a REMIC set forth in Section 860G(d) of the Code) (either such event, in the absence of an Opinion of Counsel or the indemnification referred to in this sentence, an “Adverse REMIC Event”) unless the Servicer or the REMIC Administrator, as applicable, has received an Opinion of Counsel (at the expense of the party seeking to take such action or, if such party fails to pay such expense, and the Servicer or the REMIC Administrator, as applicable, determines that taking such action is in the best interest of the Trust Estate and the Noteholders and the Certificateholders, at the expense of the Trust Estate, but in no event at the expense of the Servicer, the REMIC Administrator, the Owner Trustee or the Indenture Trustee) to the effect that the contemplated action will not, with respect to each REMIC created hereunder, endanger such status or, unless the Servicer, the REMIC Administrator or both, as applicable, determine in its or their sole discretion to indemnify the Trust Estate against the imposition of such a tax, result in the imposition of such a tax. Wherever in this Agreement a contemplated action may not be taken because the timing of such action might result in the imposition of a tax on the Trust Estate, or may only be taken pursuant to an Opinion of Counsel that such action would not impose a tax on the Trust Estate, such action may nonetheless be taken provided that the indemnity given in the preceding sentence with respect to any taxes that might be imposed on the Trust Estate has been given and that all other preconditions to the taking of such action have been satisfied. The Indenture Trustee shall not take or fail to take any action (whether or not authorized hereunder) as to which the Servicer or the REMIC Administrator, as applicable, has advised it in writing that it has received an Opinion of Counsel to the effect that an Adverse REMIC Event could occur with respect to such action. In addition, prior to taking any action with respect to any of the REMICs created hereunder or any related

assets thereof, or causing any of the REMICs to take any action, which is not expressly permitted under the terms of this Agreement, the Indenture Trustee will consult with the Servicer or the REMIC Administrator, as applicable, or its designee, in writing, with respect to whether such action could cause an Adverse REMIC Event to occur with respect to any of the REMICs, and the Indenture Trustee shall not take any such action or cause either REMIC to take any such action as to which the Servicer or the REMIC Administrator, as applicable, has advised it in writing that an Adverse REMIC Event could occur. The Servicer or the REMIC Administrator, as applicable, may consult with counsel to make such written advice, and the cost of same shall be borne by the party seeking to take the action not expressly permitted by this Agreement, but in no event at the expense of the Servicer or the REMIC Administrator. At all times as may be required by the Code, the Servicer and the Indenture Trustee will to the extent within its control and the scope of its duties more specifically set forth herein, maintain substantially all of the assets of each REMIC created hereunder as “qualified mortgages” as defined in Section 860G(a)(3) of the Code and “permitted investments” as defined in Section 860G(a)(5) of the Code.

(g) In the event that any tax is imposed on “prohibited transactions” of any of the REMICs created hereunder as defined in Section 860F(a)(2) of the Code, on “net income from foreclosure property” of any of the REMICs as defined in Section 860G(c) of the Code, on any contributions to any of the REMICs after the Startup Day therefor pursuant to Section 860G(d) of the Code, or any other tax is imposed by the Code or any applicable provisions of state or local tax laws, such tax shall be charged (i) to the Servicer, if such tax arises out of or results from a breach by the Servicer of any of its obligations under this Agreement or the Servicer has in its sole discretion determined to indemnify the Trust Estate against such tax, (ii) to the Indenture Trustee, if such tax arises out of or results from a breach by the Trustee of any of its obligations under this Article XI, or (iii) otherwise against amounts on deposit in the Custodial Account and on the Payment Date(s) following such reimbursement the aggregate of such taxes shall be allocated in reduction of the accrued interest due on each Class entitled thereto on a pro rata basis.

(h) The Indenture Trustee and the Servicer shall, for federal income tax purposes, maintain books and records with respect to each REMIC created hereunder on a calendar year and on an accrual basis or as otherwise may be required by the REMIC Provisions.

(i) Following the Startup Day, neither the Servicer nor the Indenture Trustee shall accept any contributions of assets to any of the REMICs created hereunder unless (subject to Section 11.01(f)) the Servicer and the Indenture Trustee shall have received an Opinion of Counsel (at the expense of the party seeking to make such contribution) to the effect that the inclusion of such assets in such REMIC will not cause either of the REMICs to fail to qualify as a REMIC at any time that any Group 2 Notes or Class 2A-R Certificates are outstanding or subject either of the REMICs to any tax under the REMIC Provisions or other applicable provisions of federal, state and local law or ordinances.

(j) Neither the Servicer nor the Trustee shall (subject to Section 11.01(f)) enter into any arrangement by which either of the REMICs created hereunder will receive a fee or other compensation for services nor permit either of the REMICs to receive any income from assets

(k) Solely for the purposes of Section 1.860G-1(a)(4)(iii) of the Treasury Regulations, the “latest possible maturity date” by which the Certificate Principal Balance of each Class of Group 2 Notes representing a regular interest in the applicable REMIC is the Final Payment Date.

(l) Within 30 days after the Closing Date, the REMIC Administrator shall prepare and file with the Internal Revenue Service Form 8811, “Information Return for Real Estate Mortgage Investment Conduits (REMIC) and Issuers of Collateralized Debt Obligations” for each REMIC created hereunder.

(m) Neither the Depositor, the Indenture Trustee nor the Servicer shall sell, dispose of or substitute for any of the Loans (except in connection with (i) the default, imminent default or foreclosure of a Loan, including but not limited to, the acquisition or sale of a Mortgaged Property acquired by deed in lieu of foreclosure, (ii) the bankruptcy of either of the REMICs created hereunder, (iii) the termination of the applicable REMIC pursuant to Section 3.05 of the Trust Agreement or (iv) a purchase of Loans pursuant to the Purchase Agreement) nor acquire any assets for either of the REMICs, nor sell or dispose of any investments in the Custodial Account or the Payment Account for gain nor accept any contributions to either of the REMICs after the Closing Date unless it has received an Opinion of Counsel that such sale, disposition, substitution or acquisition will not (a) affect adversely the status of either of the REMICs as a REMIC or (b) unless the Servicer has determined in its sole discretion to indemnify the Trust Estate against such tax, cause either REMIC to be subject to a tax on “prohibited transactions” or “contributions” pursuant to the REMIC Provisions.

(n) The Trustee will apply for an employer identification number from the Internal Revenue Service on a Form SS-4 or any other acceptable method for all tax entities.

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.

Capitalized terms used but not defined herein are defined in Appendix A of the Indenture.

Pursuant to the terms of the Indenture, a distribution will be made on the twenty-fifth day of each month, or, if any such date is not a Business Day, then the next Business Day.(the “Payment Date”), commencing as described in the Indenture, to the Person in whose name this Note is registered at the close of business on the last day (or if such last day is not a Business Day, the Business Day immediately preceding such last day) related Accrual Period, or, in the case of the first Payment Date, June 3, 2005, from the Group [1][2] Remittance Amount in an amount equal to the product of the Percentage Interest evidenced by this Notes and the amount of interest and principal, if any required to be distributed to Holders of Class oA-[_] Notes on such Payment Date.

Interest will be computed on the basis of the actual number of days in each Accrual Period and a year assumed to consist of 360 days.

A-1-2

Unless the certificate of authentication hereon has been executed by the Indenture Trustee whose name appears below by manual signature, this Note shall not be entitled to any benefit under the Indenture, or be valid or obligatory for any purpose.

This Note is one of a duly authorized issue of Notes of the Issuer, designated as its Home Equity Loan-Backed Notes, Series 2005-B, all issued under the Indenture, to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights and obligations thereunder of the Issuer, the Indenture Trustee and the Noteholders.

The entire unpaid principal amount of this Note shall be due and payable in full on the Final Scheduled Payment Date pursuant to the Indenture, to the extent not previously paid on a prior Payment Date. Notwithstanding the foregoing, if an Event of Default shall have occurred and be continuing, then the Indenture Trustee or the holders of Notes representing not less than a majority of the Voting Rights of all Notes may declare the Notes to be immediately due and payable in the manner provided in Section 5.02 of the Indenture.

Payments of interest on this Note due and payable on each Payment Date, together with the installment of principal, if any, to the extent not in full payment of this Note, shall be made by check mailed to the Person whose name appears as the Registered Holder of this Note (or one or more Predecessor Notes) on the Note Register as of the close of business on each Record Date, except that with respect to Notes registered on the Record Date in the name of the nominee of the Depository Agency (initially, such nominee to be Cede & Co.), payments will be made by wire transfer in immediately available funds to the account designated by such nominee.

No service charge will be charged for any registration of transfer or exchange of this Note, but the Note Registrar shall require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any registration of transfer or exchange of this Note.

Each Holder or Beneficial Owner of a Note, by acceptance of a Note, or, in the case of a Beneficial Owner of a Note, a security entitlement to a Note, covenants and agrees that no recourse may be taken, directly or indirectly, with respect to the obligations of the Issuer, the Owner Trustee, the Seller, the Servicer, the Depositor or the Indenture Trustee on the Notes or under the Indenture or any certificate or other writing delivered in connection 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 or employee 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.

Each Holder or Beneficial Owner of a Note, by acceptance of a Note or, in the case of a Beneficial Owner of a Note, a security entitlement to a Note, covenants and agrees by accepting the benefits of the Indenture that such Holder or Beneficial Owner of a Note will not prior to the day that is one year and one day after the date this Indenture terminates, institute against the Issuer or the Depositor, or join in any institution against the Issuer or the Depositor of, any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings under any United States federal or state bankruptcy or similar law in connection with any obligations relating to the Notes, the Indenture or the Basic Documents.

Each Holder or Beneficial Owner of this Note, by acceptance of this Note or a security entitlement thereto, represents that its acquisition of the Note does not constitute or give rise to a prohibited transaction under Section 406 of ERISA or Section 4975 of the Code, for which no statutory, regulatory or administrative exemption is available.

The Issuer has entered into the Indenture and this Note is issued with the intention that, for federal, state and local income, single business and franchise tax purposes, the Notes will qualify as indebtedness of the Issuer. Each holder of a Note, by acceptance of a Note (and each Beneficial Owner of a Note by acceptance of a security entitlement to a Note), agrees to treat the Notes for federal, state and local income, single business and franchise tax purposes as indebtedness of the Issuer.

Prior to the due presentment for registration of transfer of this Note, the Issuer, the Indenture Trustee and any agent of the Issuer or the Indenture Trustee may treat the Person in whose name this Note is registered (as of the day of determination or as of such other date as may be specified in the Indenture) as the owner hereof for all purposes, whether or not this Note

A-1-4

be overdue, and none of the Issuer, the Indenture Trustee or any such agent 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 Indenture Trustee and the rights of the holders of the Notes under the Indenture at any time by the Issuer and the Indenture Trustee with the consent of the holders of Notes representing a majority of the Voting Rights of all Notes at the time Outstanding and with prior notice to the Rating Agencies. The Indenture also contains provisions permitting the holders of Notes representing specified percentages of the Voting Rights of all Notes, on behalf of the holders of all the Notes, to waive compliance by the Issuer with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the holder of this Note (or any one of more Predecessor Notes) shall be conclusive and binding upon such holder and upon all future holders of this Note and of any Note 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 this Note. 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 Noteholders but with prior notice to the Rating Agencies.

The term “Issuer” as used in this Note includes any successor or the Issuer under the Indenture.

The Issuer is permitted by the Indenture, under certain circumstances, to merge or consolidate, subject to the rights of the Indenture Trustee and the Noteholders.

The Notes are issuable only in registered form in denominations as provided in the Indenture, subject to certain limitations therein set forth.

This Note and the 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 and thereunder shall be determined in accordance with such laws.

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair, the obligation of the Issuer, which is absolute and unconditional, to pay the principal of and interest on this Note at the times, place and rate, and in the coin or currency herein prescribed.

Anything herein to the contrary notwithstanding, except as expressly provided in the Basic Documents, none of U.S. Bank National Association, in its individual capacity, Wilmington Trust Company, in its individual capacity, any owner of a beneficial interest in the Issuer, or any of their respective partners, beneficiaries, agents, officers, directors, employees or successors or assigns shall be personally liable for, nor shall recourse be had to any of them for, the payment of principal of or interest on this Note or performance of, or omission to perform, any of the covenants, obligations or indemnifications contained in the Indenture. The holder of this Note by its acceptance hereof agrees that, except as expressly provided in the Basic Documents, in the case of an Event of Default under the Indenture, the holder shall have no

A-1-5

claim against any of the foregoing for any deficiency, loss or claim therefrom; provided, however, that nothing contained herein shall be taken to prevent recourse to, and enforcement against, the assets of the Issuer for any and all liabilities, obligations and undertakings contained in the Indenture or in this Note.

ΔY₂ =	the REMIC I Regular Interest LT2 Principal Reduction Amount.

ΔY₃ =	the REMIC I Regular Interest LT3 Principal Reduction Amount.

ΔY₄ =	the REMIC I Regular Interest LT4 Principal Reduction Amount.

P₀ =	the aggregate principal balance of the REMIC I Regular Interests LT1, LT2, LT3 and LT4 after distributions and the allocation of Realized Losses on the prior Payment Date.

Appendix A-41

P₁ =	the aggregate principal balance of the REMIC I Regular Interests LT1, LT2, LT3 and LT4 after distributions and the allocation of Realized Losses to be made on such Payment Date.

ΔP =	P₀ - P₁ = the aggregate of the REMIC I Regular Interests LT1, LT2, LT3 and LT4 Principal Reduction Amounts, which

=	the aggregate of the principal portions of Realized Losses to be allocated to, and the principal distributions to be made on, the Group 2 Notes and Group 2 Certificates on such Payment Date (including distributions of accrued and unpaid interest on the Class SB Notes for prior Payment Dates).

R₀ =	the Group 2 Maximum Interest Rate (stated as a monthly rate) after giving effect to amounts distributed and Realized Losses allocated on the prior Payment Date.

R₁ =	the Group 2 Maximum Interest Rate (stated as a monthly rate) after giving effect to amounts to be distributed and Realized Losses to be allocated on such Payment Date.

γ₀ =	the lesser of (A) the sum of (x) the sum for all Classes of Group 2 Notes, of the product for each Class of (i) the monthly interest rate (as limited by the Group 2 Maximum Interest Rate, if applicable) for such Class applicable for distributions to be made on such Payment Date and (ii) the aggregate Class Principal Balance for such Class after distributions and the allocation of Realized Losses on the prior Payment Date and (y) the sum of the amounts defined in clauses (2) and (3) of the definition of Group 2 Basis Risk Shortfall for such Payment Date and (B) R₀*P₀.

γ₁ =	the lesser of (A) the sum of (x) the sum for all Classes of Group 2 Notes, of the product for each Class of (i) the monthly interest rate (as limited by the Group 2 Maximum Interest Rate, if applicable) for such Class applicable for distributions to be made on the next succeeding Payment Date and (ii) the aggregate Class Principal Balance for such Class after distributions and the allocation of Realized Losses to be made on such Payment Date and (y) the sum of the amounts defined in clauses (2) and (3) of the definition of Group 2 Basis Risk Shortfall for such next succeeding Payment Date and (B) R₁*P₁.

Then, based on the foregoing definitions:

ΔY₁ =	ΔP - ΔY₂ - ΔY₃ - ΔY₄;
ΔY₂ =	(α/2){( γ₀R₁ - γ₁R₀)/R₀R₁};
ΔY₃ =	αΔP - ΔY₂; and
ΔY₄ =	ΔY₃.

if both ?Y₂ and ?Y₃, as so determined, are non-negative numbers. Otherwise:

Appendix A-42


ΔY₂ = 0;

ΔY₃ = α{γ₁R₀P₀ - γ₀R₁P₁}/{γ₁R₀};

ΔY₄ = ΔY₃; and

ΔY₁ = ΔP - ΔY₂ - ΔY₃ - ΔY₄.

(2) If ΔY₃, as so determined, is negative, then

ΔY₃ = 0;

ΔY₂ = α{γ₁R₀P₀ - γ₀R₁P₁}/{2R₁R₀P₁ - γ₁R₀};
