Section 11.6 Each Series Separate; Assignees of Series. It is intended by the parties hereto that Series 2005-SN1 is a separate series of the Trust as provided in Section 3806(b)(2) of the Statutory Trust Act. The debts, liabilities, obligations and expenses incurred, contracted for or otherwise existing with respect to Series 2005-SN1 or 5 the Series 2005-SN1 Lease Assets shall be enforceable against the Series 2005-SN1 Portfolio only, and not against any other Trust Assets or the Residual Trust Assets. Except to the extent required by law or specified in the Declaration of Trust or this COLT Series Supplement, the Series 2005-SN1 Lease Assets are not subject to claims, liabilities, expenses or obligations arising from or with respect to the Trust, the COLT Owner Trustee, the Residual Interest or any other Series in respect of such claim. No creditor or holder of a claim relating to assets allocated to Series 2005-SN1 shall be entitled to maintain any action against or recover any assets allocated to the Residual Interest or any other Series. Notice of this limitation on interseries liabilities shall be set forth in the certificate of trust of the Trust (whether originally or by amendment) as filed or to be filed in the Office of the Secretary of State of the State of Delaware pursuant to the Statutory Trust Act, and upon the giving of such notice in the certificate of trust, the statutory provisions of Section 3804 of the Statutory Trust Act relating to limitations on interseries liabilities (and the statutory effect under Section 3804 of setting forth such notice in the certificate of trust) shall become applicable to the Trust and each Series and the Residual Interest. Any purchaser, assignee or pledgee of an interest in Series 2005-SN1 or the COLT 2005-SN1 Certificate must, prior to or contemporaneously with the grant of any such assignment, pledge or security interest, (i) give to the Trust a no petition covenant substantially similar to that set forth in Section 8.8 of the Declaration of Trust, and (ii) execute an agreement for the benefit of each holder, assignee or pledgee from time to time of the Residual Interest or Residual Certificate and any other Series or Series Certificate, to release all claims to the assets of the Trust allocated to the Residual Interest and each other Series Portfolio and in the event that such release is not given effect, to fully subordinate all claims it may be deemed to have against the assets of the Trust allocated to the Residual Interest and each other Series Portfolio. In the event of a sale or assignment of a Series, such purchaser or assignee shall be a beneficiary of the Trust in the manner and to the extent set forth in the Series Certificate so acquired and in the applicable COLT Series Supplement. Section 11.7 Nonpetition; Release of Claims. Notwithstanding any other provision of the Declaration of Trust, this COLT Series Supplement, any other Basic Document or any other COLT 2005-SN1 Basic Document and notwithstanding any prior termination of the Declaration of Trust or this COLT Series Supplement, each Certificateholder and the COLT Owner Trustee shall not, prior to the date which is one year and one day after the termination of the Declaration of Trust with respect to the Trust, acquiesce, petition or otherwise invoke or cause the Trust to invoke the process of any Governmental Authority for the purpose of commencing or sustaining a case against the Trust 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 Trust or any substantial part of its property, or ordering the winding up or liquidation of the affairs of the Trust. Section 11.8 Tax Matters. Each of the Residual Certificateholder and the COLT Owner Trustee agree that for federal and state income tax purposes it shall not treat this COLT Series Supplement as creating or constituting a trust, partnership, association taxable as a corporation or any other type of separate entity (and will report for such purposes in a consistent manner therewith). Instead, it is 6 the intention of the parties hereto that, solely for purposes of federal income taxes, state and local income and franchise taxes, Michigan single business tax and any other taxes imposed upon, measured by or based upon gross or net income, the Trust shall be treated (i) when the Certificates are legally or beneficially owned by two or more Persons, as a partnership and (ii) when the Certificates are legally or beneficially owned by one Person, as a disregarded entity for purposes of Treasury Regulation 301.7701-3, and in each case, that the provisions of this COLT Series Supplement shall be construed in accordance with such intent. Each such party further agrees that the Trust is acting as holder of record title to the 2005-SN1 Series Portfolio, other than the Vehicles contained therein, solely for the benefit of, and as agent and nominee of, the holder of the COLT 2005-SN1 Certificate, and shall not hold itself out or act in a manner inconsistent with it acting merely as agent and nominee.

A summary of certain of the pertinent portions of the Declaration of Trust is set forth below. To the extent not otherwise defined herein, capitalized terms used herein have the meanings set forth in Part I of Exhibit I to the Declaration of Trust. This Certificate is the duly authorized certificate issued under the Declaration of Trust and the Series 2005-SN1 Supplement to the Declaration, and is designated as "Central Originating Lease Trust 2005-SN1 Certificate" (the "COLT 2005-SN1 Certificate"). This COLT 2005-SN1 Certificate is issued under and is subject to the terms, provisions and conditions of the Declaration of Trust (including the Series 2005-SN1 Supplement to the Declaration), the terms of which are incorporated herein by reference and made a part hereof, to which Declaration of Trust the holder of this COLT 2005-SN1 Certificate by virtue of the acceptance hereof assents and by which such holder is bound.

The Residual Certificate evidences an exclusive, divided interest in the Trust Assets other than Trust Assets allocated to a particular Series (each as defined in the Declaration of Trust), and each series of Series Certificates, taken together, will evidence an exclusive divided interest in a separate Series Portfolio (as defined below). The Declaration of Trust provides that, from time to time, certain of the Trust Assets will be identified and allocated on the records of the Trust into one or more separate portfolios of Trust Assets (each such portfolio, a "Series Portfolio"). The equity beneficial interest in each such Series Portfolio will constitute a separate series of equity beneficial interest" (a "Series") in the Trust. Pursuant to the Series 2005-SN1 Supplement to the Declaration, various Trust Assets (the "Series 2005-SN1 Lease Assets") were identified and allocated on the records of the Trust into a separate Series Portfolio (the "Series 2005-SN1 Portfolio"), and the equity beneficial interest in the Series 2005-SN1 Portfolio was designated as a separate Series known as the "Series 2005-SN1." The rights of the holder of this Certificate to the proceeds of the Series 2005-SN1 Lease Assets are and will be further set forth in the Declaration of Trust and the Series 2005-SN1 Supplement to the Declaration.

This Certificate is limited in right of payment to certain collections and recoveries respecting the Series 2005-SN1 Lease Assets allocated to the Series 2005-SN1 Portfolio, all to the extent and as more specifically set forth in the Declaration of Exhibit A-2 Trust.

No bankruptcy, reorganization arrangement, insolvency or liquidation proceeding or other proceedings under any federal or state bankruptcy, insolvency or similar law shall be instituted by the Trust without the consent of the COLT Owner Trustee. The COLT Owner Trustee shall not so consent unless directed to do so by all of the Certificateholders. Prior to due presentation of this Certificate for registration of a permitted transfer, the COLT Owner Trustee, the certificate registrar and any of their respective agents may treat the person or entity in whose name this Certificate is registered as the owner hereof for the purpose of receiving distributions and for all other purposes, and, except as provided for in the Declaration of Trust, neither the COLT Owner Trustee, the certificate registrar nor any such agent shall be affected by any notice to the contrary.
