Spartech Expects to Cut Over $1 Million in Energy Costs With World Energy Solutions

ST. LOUIS, MO and WORCESTER, MA, May 22 (Marketwire)
--
World Energy Solutions, Inc. (NASDAQ: XWES), a fast-growing energy
management services firm, today announced it has won a new three year
energy management contract with Spartech Corporation (NYSE: SEH), a
leading producer of plastic sheet, compounds and packaging solutions. The
contract encompasses a broad swath of sustainability and transactional
services intended to help Spartech lower its energy commodity costs,
reduce energy consumption, and maximize available grid and utility
incentives, such as demand response and efficiency rebates.

In the first three months of the engagement, World Energy has leveraged
its deep energy-market expertise and extensive supplier network to
successfully procure electricity and renewable energy for Spartech
facilities in Maryland, New York, Ohio and Texas. These online
procurements, executed after careful analysis of the Spartech portfolio
and in accordance with an Opportunity Assessment developed by World
Energy on the Company's behalf, are expected to deliver over $1 million
in savings over Spartech's prior contracts.

"World Energy's approach to energy management represents a big
improvement for us, and the results are speaking for themselves," said
Victoria Holt, President & CEO of Spartech Corporation. "Not only has
World Energy delivered a plan for seven-figure savings to our
organization -- and begun executing upon it in short order -- but it has
done so in some markets where we had been told limited opportunities
existed. We are benefitting from World Energy's process and market
expertise, their ability to create liquidity and transact in multiple
geographies, and the transparent manner in which they operate.

"Spartech is committed to its Vision of becoming the leading supplier of
sustainable plastic solutions by minimizing our impact upon the
environment by reducing material consumption, adopting cleaner processes
and pursuing more efficient use of energy. World Energy serves as a good
partner in this important endeavor, helping us move closer to realizing
this Vision."

Added Richard Domaleski, CEO of World Energy Solutions: "By keeping our
focus on delivering value to our customers, we have established an
unmatched track record that resonates from the C-suite of the Fortune 100
to the owners and operators of small and mid-sized businesses. There is
so much more that companies can be getting from energy management, but
they need to be working with the right provider, one who has their best
interests in mind and the skill to get the most from the market on their
behalf. We appreciate the opportunity to collaborate with Spartech to
meet their energy management and sustainability goals, while driving down
their total cost of energy."

Throughout 2012, World Energy will be rolling out bill-payment services
for Spartech, conducting efficiency work, and executing additional
electricity and natural gas procurements across the country. For more
