An arbitration panel on Thursday awarded $860,000 to two former Thomas Kinkade Signature Gallery owners who accused the self-proclaimed "Painter of Light" and his company, Media Arts Group Inc., of fraudulently inducing them to invest in the business — and then ruining them financially. While not singling out Kinkade in its finding of fraud, the panel ruled that the Morgan Hill, Calif.-based company and one of its executives, Richard F. Barnett, "failed to disclose material information" that would have dissuaded Karen Hazlewood and Jeffrey Spinello from investing $122,000 to open the first of their two Virginia galleries in 1999.
