About ESI

ESI is a leading manufacturer of patented and proprietary solutions for
environments where understanding the presence, movement, and/or amount of water
are important. Major market sectors include: agriculture, golf and turf,
scientific research, civil engineering, mining, environmental monitoring and
crude oil production. ESI soil moisture sensing solutions have been successfully
introduced into more than 40 countries to enable customers to optimize their
operations by monitoring the presence and movement of water, managing irrigation
systems, and monitoring the integrity of landfill covers. In addition, ESI's
FloPoint(TM) instrument has been deployed in the oil industry to measure the
volumetric presence of water pumped during crude oil extraction ("water cut")
for characterization and optimization of the process. ESI differentiates itself
by translating the best technology and science available into practical, easy to
use solutions. Irrigation managers, reservoir engineers, and scientists have
adopted ESI's products for their accuracy, ease of use, repeatability, and
ability to operate in challenging environments. ESI is publicly traded on the
