(c) Without limiting the generality of the foregoing, the Trust Administrator is hereby authorized and empowered by the Owner of the COLT 2005-SN1 Secured Notes, pursuant to this Section 3.01, to execute and deliver, on behalf of all Interested Parties, or any of them, any and all instruments of satisfaction or cancellation, or of partial or full release or discharge, and all other comparable instruments, with respect to the COLT 2005-SN1 Secured Notes.

Except to the extent required by the preceding two sentences, the authority and rights granted to the Trust Administrator in this Section 3.01 shall be nonexclusive and shall not be construed to be in derogation of the retention by the Owner of a COLT 2005-SN1 Secured Note of equivalent authority and rights. SECTION 3.02 Maintenance of Security Interests in COLT 2005-SN1 Secured Notes. The Trust Administrator shall, in accordance with its customary practices, policies and procedures and at its own expense, take such steps as are necessary to maintain perfection of the security interest created by each COLT 2005-SN1 Secured Note in the Series 2005-SN1 Lease Assets and other First Step Purchased Property as set forth in Section 2.09 of the COLT Servicing Agreement.

It is understood and agreed that the obligation of the Trust Administrator to purchase any COLT 2005-SN1 Secured Note with respect to which such a breach has occurred and is continuing shall, if such obligation is fulfilled, constitute the sole remedy against the Trust Administrator for such breach available to CARI or any Interested Party. SECTION 3.05 Administration Fee; Payment of Certain Expenses by Trust Administrator. The Trust Administrator is entitled to receive the Administration Fee out of payments on the COLT 2005-SN1 Secured Notes.

GMAC makes the following representations and warranties as to the COLT 2005-SN1 Secured Notes related thereto on which CARI relies in accepting the COLT 2005-SN1 Secured Notes. Such representations and warranties speak as of the Series 2005-SN1 Closing Date, and shall survive the sale, transfer and assignment of the COLT 2005-SN1 Secured Notes and the other First Step Purchased Property to CARI and the subsequent assignment and transfer pursuant to the Further Transfer and Administration Agreements: (a) Custody of COLT 2005-SN1 Secured Notes. GMAC has instructed the Secured Note Registrar to identify the CARAT Indenture Trustee as the registered holder of the COLT 2005-SN1 Secured Notes, in each case in the Secured Note Register. (b) Terms of COLT 2005-SN1 Secured Notes. Each COLT 2005-SN1 Secured Note: (i) was issued by COLT to fund a portion of the purchase price of the related pool of Series 2005-SN1 Lease Assets, (ii) has created or shall create a valid, binding and enforceable first priority security interest in favor of GMAC or the COLT Indenture Trustee on behalf of GMAC in the Series 2005-SN1 Lease Assets, which security interest is assignable by GMAC to CARI, (iii) contains enforceable provisions to render the rights and remedies of the holder thereof adequate for realization against the collateral of the benefits of the security, (iv) shall yield interest at the rate set forth in such COLT 2005-SN1 Secured Note and (v) prior to the sale of the COLT 2005-SN1 Secured Notes to CARI under this Agreement, the COLT 2005-SN1 Secured Notes constitute "chattel paper," "payment intangibles," "promissory notes" or "certificated securities" within the meaning of the applicable UCC. (c) Binding Obligation. Each COLT 2005-SN1 Secured Note represents the genuine, legal, valid and binding payment obligation of COLT thereon, in each case enforceable by the holder thereof in accordance with its terms, except as enforceability may be limited by bankruptcy, insolvency, reorganization or similar laws affecting the enforcement of creditors' rights in general and by equity, regardless of whether such enforceability is considered in a proceeding in equity or at law. (d) COLT 2005-SN1 Secured Notes in Force. No COLT 2005-SN1 Secured Note has been satisfied, subordinated or rescinded, and the related Series 2005-SN1 Lease Assets securing each such COLT 2005-SN1 Secured Note have not been released from the Lien of the related COLT 2005-SN1 Secured Note in whole or in part. 8 (e) No Waiver or Amendment. Since the Series 2005-SN1 Closing Date, no provision of a COLT 2005-SN1 Secured Note has been waived, amended or modified in any respect. (f) No Defenses. No right of rescission, setoff, counterclaim or defense has been asserted or threatened with respect to any COLT 2005-SN1 Secured Note. (g) No Liens. To the best of GMAC's knowledge: (1) there are no liens or claims that have been filed for work, labor or materials affecting any Series 2005-SN1 Lease Assets securing any COLT 2005-SN1 Secured Note that are or may be liens prior to, or equal or coordinate with, the security interest in the Series 2005-SN1 Lease Assets granted by the COLT 2005-SN1 Secured Note and (2) no tax lien has been filed and no claim related thereto is being asserted with respect to any COLT 2005-SN1 Secured Note; no contribution failure has occurred with respect to any Pension Plan which is sufficient to give rise to a lien under Section 302(f) of ERISA with respect to any COLT 2005-SN1 Secured Note. (h) Good Title. No COLT 2005-SN1 Secured Note has been sold, transferred, assigned or pledged by GMAC to any Person other than CARI. Immediately prior to the conveyance of the COLT 2005-SN1 Secured Notes pursuant to this Agreement and the First Step Secured Notes Assignment, GMAC had good and marketable title thereto, free of any Lien. Upon execution and delivery of this Agreement by GMAC, CARI shall have all of the right, title and interest of GMAC in and to the COLT 2005-SN1 Secured Notes, the unpaid indebtedness evidenced thereby and the collateral security therefor, free of any Lien. (i) Lawful Assignment. No COLT 2005-SN1 Secured Note was issued, or is subject to the laws of, any jurisdiction the laws of which would make unlawful the sale, transfer and assignment of such COLT 2005-SN1 Secured Note under this Agreement, the Trust Sale and Administration Agreement or the CARAT Indenture, as applicable. (j) All Filings Made. All filings (including UCC filings) necessary in any jurisdiction to give CARI a first priority perfected ownership interest in the First Step Purchased Property have been made. Other than the security interest granted to CARI pursuant to this Agreement, GMAC has not pledged, assigned, sold, granted a security interest in, or otherwise conveyed any of the COLT 2005-SN1 Secured Notes; GMAC has not authorized the filing of, and is not aware of, any financing statements against GMAC that include a description of collateral covering the COLT 2005-SN1 Secured Notes other than the financing statements relating to the security interests granted to CARI under this Agreement, or any financing statement that has been terminated. GMAC is not aware of any judgment or tax lien filings against it. (k) Maturity of COLT 2005-SN1 Secured Notes. Each COLT 2005-SN1 Secured Note has a maturity date on December 15, 2009. (l) Security Interest Created. While it is the intention of GMAC and CARI that the transfer and assignment contemplated by this Agreement and the First Step Secured Notes Assignment shall constitute the sale of the COLT 2005-SN1 Secured Notes from GMAC to CARI, this Agreement creates a valid and continuing security interest (as defined in the 9 applicable UCC) in the COLT 2005-SN1 Secured Notes in favor of CARI which security interest is prior to all other Liens, and is enforceable as such as against creditors of and purchasers from GMAC. SECTION 4.02 Additional Representations and Warranties of GMAC.
