For the twelve months of fiscal 2008, net income from continuing operations was $495,000, or $0.10 per basic and diluted share, compared to net income of $1.6 million, or $0.32 per basic and diluted share for fiscal 2007.

The net loss from discontinued operations was $152,000, or $0.03 per basic and diluted share, in the quarter ended September 30, 2008 compared to a net loss of $411,000, or $0.08 per basic and diluted share, in the same period last year. This resulted in a net loss from all operations in the fourth quarter of $1.1 million, or $0.22 per basic and diluted share, compared to a net loss in the same quarter of the prior fiscal year of $203,000, or $0.04 per basic and diluted share.
