year's numbers are again expected to increase. A total of over 5,000

years and 2009 was no exception," said Richard Baker, senior vice president of
power for PennWell. "Our association partners, corporate sponsors and growing
number of exhibitors are instrumental in making this the premiere
all-renewable event in the world. Our host utility, NV Energy, exceeded
expectations when it came to their support and involvement."

successful launch to the utility industry at DistribuTech, we were excited to
keep the momentum going with our debut presence at Renewable Energy World 2009
in Las Vegas," said Therese Wells, Director of Marketing for Ice Energy. "The
visibility and exposure we generated there among key influencers has been
invaluable for us as we establish the importance of energy storage as a key
enabling technology for the renewable industry. We are excited to be back
again in 2010. From DistribuTech to PowerGen to Renewable Energy World,
PennWell's global energy conferences are a fundamental cornerstone of our
event strategy."

"Renewable Energy World and Power-Gen are the premier power industry trade
shows in the United States," said Chris Huntington, Vice President of Business
Development for SkyFuel. "For SkyFuel, these are the crucial venues in which
to meet the customers, suppliers and developers with whom we hope to create a
new paradigm in the power industry; one in which utility scale solar power is
no longer a marginal alternative but a mainstream option.
