Description of Updated Reportable Segments

The Company’s updated reportable segments shown above and their principal activities consist of the following:

Laser Products

The Laser Products segment designs, manufactures, and markets photonics-based solutions, consisting of lasers and laser-based systems, to customers worldwide. The Laser Products segment provides the industrial, scientific, medical, packaging, aerospace and homeland security markets with applications that include cutting, welding, drilling, micro-machining, scientific research, remote sensing, surface marking, and deep engraving of metal and plastic parts. Many of the products are customized for the customer. The Laser Products segment sells these products both directly utilizing a highly technical sales force and indirectly through resellers and distributors.

Precision Motion and Technologies

The Precision Motion and Technologies segment designs, manufactures and markets air bearing spindles, encoders, precision motion devices, thermal printers, and light and color measurement systems to customers worldwide. The majority of these products are based on the segment’s core competencies in precision motion and motion control technologies. The vast majority of the segment’s product offerings are sold to original equipment manufacturers (“OEM’s”). These products are used in the electronics, aerospace, materials processing, data storage, imaging and other light industrial markets. The Precision Motion and Technologies segment sells these products both directly utilizing a highly technical sales force and indirectly through resellers and distributors.

Semiconductor Systems

The Semiconductor Systems segment designs, develops and sells production systems that process semiconductor wafers using laser beams and high precision technology. The systems manufactured by the Company’s Semiconductor Systems segment are sold to integrated device manufacturers and wafer processors. The Semiconductor Systems segment’s systems perform laser-based processing on all of the following types of semiconductors: general wafers used for logic or memory purposes, dynamic random access memory (DRAM, “Not And” or NAND) chips and high performance analog chips.
