Through its subsidiaries, Careal is primarily engaged in a wholesale and retail distributorship in Switzerland for foreign automobiles and parts and in a real estate business in Switzerland.  Mr. Haefner is Chairman of Careal and Ms. Bucher-Haefner is director of the board of Careal.  BigPoint is a holding company for certain of Mr. Haefner’s investments. Mr. Haefner is the sole director of BigPoint and BigPoint has no officers. The principal place of business of each of Careal, Martin Haefner, BigPoint and Ms. Bucher- Haefner is Utoquai 49, 8022 Zurich, Switzerland.

The information required by this Item with respect to the directors and officers of Careal is furnished in Schedule A and incorporated by reference.

On November 26, 2015 Careal transferred 37,050,000 shares of Common Stock to BigPoint, a company wholly owned by Mr. Haefner, to repurchase shares of Careal held by BigPoint. The transfer was in connection with the Company’s repurchase of shares of Common Stock from Careal on November 20, 2015.  Carael used the cash proceeds from such repurchase, plus additional cash, to repurchase shares of Careal owned by Ms. Bucher-Haefner.  These actions allow Mr. Haefner and Ms. Bucher-Haefner to maintain their respective 50% ownership interest in Careal.
