Award Recognizes 100 Private Companies in North America That Drive the
                         Technology Industry's Future

    HAYWARD, Calif., May 12 /PRNewswire/ -- Dust Networks,
(http://www.dustnetworks.com), the leading provider of enterprise-class, low-power
wireless mesh networking systems, today announced that it has been named one
of the Red Herring 100 Private Companies of North America.
    "We're honored to receive this award from Red Herring -- it is a great
recognition of the impact Dust Networks' wireless mesh networking products are
having on the market," said Joy Weiss, President and CEO of Dust Networks.
    "Five years after the dot-com bubble burst, innovation and
entrepreneurship are thriving. The companies on this list are proof," said Red
Herring editor-in-chief Joel Dreyfuss.
    Dust Networks' low-power wireless mesh networking systems are optimized to
easily and reliably collect data about physical assets and environments
-- whether on factory floors, around building perimeters, in energy monitoring
systems, or in a host of other areas.  These completely wireless systems open
up opportunities for companies to increase visibility into business operations
and decisions, improve control and manageability of critical building or plant
systems, and drive cost savings around using resources more intelligently or
efficiently.  From a building owner looking to reduce energy costs to a plant
manager developing a proactive maintenance schedule, wireless sensor networks
are driving a host of enterprise monitoring and control applications.
    Red Herring's lists of private companies are an important part of the
magazine's tradition of identifying new and innovative technology companies
and entrepreneurs. Companies like Google and eBay were spotted in their early
days by Red Herring editors as those that would change the way we live and
work.
    Red Herring's editorial staff rigorously evaluated more than 900 private
companies through a careful analysis of financial data and subjective
criteria, including quality of management, execution of strategy, and
dedication to research and development.  Red Herring 100 companies will be
presenting their business model and strategy at the Red Herring Spring
conference.  Red Herring Spring will take place May 17-19 at the Monterey
Plaza Hotel in Monterey, California.
    Dust Networks' Joy Weiss, President & CEO, will be at Red Herring Spring
participating on a panel on "Emerging Technologies" and delivering a
presentation on the applications of wireless sensor networks.  For more
