The Certificate has been validly issued, subject to applicable bankruptcy, insolvency, reorganization and similar laws affecting creditors' rights generally and subject to general principles of equity (regardless of whether enforcement is sought in a proceeding at law or in equity). 2. Each series of Notes will be validly issued and binding obligations of the Issuer, fully paid and non-assessable, subject to applicable bankruptcy, insolvency, reorganization and similar laws affecting creditors' rights generally and subject to general principles of equity (regardless of whether enforcement is sought in a proceeding in equity or at law). In addition, we have assumed that (i) the Pooling and Servicing Agreement, the Series 2002-CC Supplement and the Indenture have been duly authorized by all necessary action by the parties thereto and have been duly executed and delivered by the parties thereto, (ii) the Certificate has been duly executed, authenticated and delivered as described in the Registration Statement, (iii) a Series Indenture Supplement for a series of Notes will have been duly authorized by all necessary action by the parties thereto and will have been duly executed and delivered by the parties thereto, (iv) the Notes issued pursuant to the Indenture and the Series Indenture Supplement will have been duly executed, authenticated and delivered and paid for as described in the prospectus supplement and (v) the Indenture, the Series Indenture Supplement and the related Notes, as applicable, and the Pooling and Servicing Agreement, the Series 2002-CC Supplement and the Certificate, as applicable, have been or will be executed and delivered in substantially the form filed as exhibits to the Registration Statement with such changes acceptable to us, and that such Notes will be sold as described in the Registration Statement.
