The
Sponsor and the Servicer



The
sponsor is subject to various pending and potential legal and regulatory proceedings in the ordinary course of business, including litigation,
arbitration, claims, investigations, examinations, subpoenas and enforcement proceedings. Some litigation against the sponsor could take
the form of class actions. The outcomes of these proceedings are inherently uncertain, and thus the sponsor cannot confidently predict
how or when these proceedings will be resolved. An adverse outcome in one or more of these proceedings could result in substantial damages,
settlements, fines, penalties, diminished income or reputational harm to the sponsor, and could materially and adversely affect the interest
of the noteholders or the servicer’s ability to perform its duties under the transaction documents.
