Our Company • Founded in 1968 by Dr. John Swartz as Lake Shore Cryotronics • World leader in measurement & control technologies. • Continual investment in research & development • Establishment of Industrial Division (Lakeshore) in 1990 by Joe Bioty • Renamed North. Star in 1997 • Became part of Danaher in May 2001 Confidential 2

The Challenge • Need by major motor manufacturer to develop reliable digital tachometer – – A device to measure the shaft velocity of electric motors. Bearingless, non-contact design Withstand rigors of heavy industry Easy to mount and maintain with minimal parts Confidential 3

The Solution – Magnetoresistive Technology • • Rugged pulse wheel, magnetically encoded High resolution Bearingless Non-contact sensing Unaffected by dirt, grease, and grime Replaces gear tooth wheels and optical disks Stands up to the rigors of heavy industry Confidential 4

Key Product Benefits • • • Magneto-resistive technology Fast installation Easy maintenance Rugged construction Resistance to contaminants Digital reliability Confidential 5
