The 2004-RN2 Revolving Note is one of the duly authorized series of Notes of the Issuer issued and to be issued from time to time pursuant to the Indenture (collectively, as to all Notes of all such series, the “Notes”).

All capitalized terms used and not otherwise defined in this Note that are defined in the Indenture shall have the meanings assigned to them in or pursuant to the Indenture.

The 2004-RN2 Revolving Note and all other Notes issued pursuant to the Indenture, except as otherwise provided thereunder, are and shall be equally and ratably secured by the Collateral pledged as security therefor as provided in the Indenture.

Each Noteholder, by acceptance of 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 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 their individual capacities, (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 their individual capacities, 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 their individual capacities, except as any such Person may have expressly agreed and except that any such partner, owner or beneficiary shall be fully liable, to the extent provided by applicable law, for any unpaid consideration for stock, unpaid capital contribution or failure to pay any installment or call owing to such entity.

Each Noteholder, by acceptance of a Note, covenants and agrees that by accepting the benefits of the Indenture such Noteholder shall not, prior to the date which is one year and one day after the termination of the Trust Agreement, acquiesce, petition or otherwise invoke or cause the Seller or the Issuer to invoke the process of any court or government authority for the purpose of commencing or sustaining a case against the Seller or the Issuer under any federal or state bankruptcy, insolvency or similar law or appointing a receiver, liquidator, assignee, trustee, custodian, sequestrator or other similar official of the Seller or the Issuer or any substantial part of its property, or ordering the winding up or liquidation of the affairs of the Seller or the Issuer.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Issuer and the rights of the Noteholders under the Indenture at any time by the Issuer with the consent of the Holders of Notes representing a majority of the Outstanding Amount of all the Notes. The Indenture also contains provisions permitting the Holders of Notes representing specified percentages of the Outstanding Amount of the 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.
