FPCG’s advisory clients are the owners of 727,454 shares of the Common Stock representing approximately 1.85% of the outstanding shares of Common Stock.

Johnson, Jr. (the “Principal Shareholders”) each own in excess of 10% of the outstanding Common Stock of FRI and are the principal shareholders of FRI.
