The Shareholder Agreement provides further that, until the final

owned by him or any of his affiliates or associates to be voted
in accordance with the recommendation of the Companys Board of
Directors with respect to election and removal of directors,
certain routine matters and any other proposal to be submitted to
the Companys shareholders with respect to any extraordinary
transaction providing for the acquisition of all of the Companys
outstanding common stock. The Shareholder Agreement requires that
Mr. Foss not, and that Mr. Foss cause his affiliates and
associates not to, tender or exchange any of the Companys common
stock in connection with any tender or exchange offer for all of
the Companys outstanding common stock unless the Companys Board
of Directors has publicly recommended the acceptance of such
offer and has not publicly withdrawn or changed such
recommendation. The Shareholder Agreement requires that Mr. Foss
not solicit Company employees for employment and that he
terminate his direct and indirect financial support for certain
automobile dealerships and any other companies engaged in
automobile lease financing or indirect retail auto financing. The
Shareholder Agreement also includes a mutual non-disparagement
provision, a release by the Company of claims against Mr. Foss
relating to his ownership, operation or control of certain
automobile dealerships or other companies engaged in automobile
lease financing or indirect retail auto financing and a release
by Mr. Foss of claims against the Company relating to such
ownership, operation or control or to Mr. Fosss resignation from
the Companys Board of Directors or from his position as the
Companys Chairman of the Board. The releases are subject to
termination by the Company under certain circumstances.

Mr. Foss has advised the Company that, as of January 3, 2017, he
beneficially owned 3,914,492 shares of the Companys common stock.

Fosss sons nephew, beneficially owned 2,022,243 shares of the
Companys common stock as of December 31, 2016. In the normal
course of the Companys business, dealers owned or controlled by
Mr. Foss or a member of Mr. Fosss immediate family assign
consumer loans to the Company under the Companys portfolio and
purchase programs on the same terms as those applicable to the
Companys loan assignments from non-affiliated dealers.
