In that connection, we are generally familiar with the proceedings taken or to be taken in connection with the proposed authorization, issuance and sale of the Notes, and have examined and relied upon copies of such statutes, documents, corporate records and other instruments as we have deemed necessary or appropriate for the purposes of this opinion, including the Prospectus, the Underwriting Agreement and current drafts of the Indenture (including the form of the Notes included as an exhibit thereto), the Receivables Sale Agreement, the Sale Agreement, the Servicing Agreement, the Administration Agreement, the Asset Representations Review Agreement and the Trust Agreement. Terms used herein without definition have the meanings given to such terms in, or by reference in, the Indenture.
