The Company narrowed its net loss during the quarter and six months ended June 30, 2003 compared to the same period in 2002, primarily due to an increase in DataPlace label placement machine and custom factory automation equipment sales, the effects of cost cutting in prior quarters, and due to increased manufacturing efficiencies in the Amistar Manufacturing Services division.
