"Duke is pleased to expand our relationship with Ambient through the execution
of this agreement. Ambient's two-way communication node advances our vision
of building a smart grid intelligent network that supports the integration of
numerous devices on the grid," said Todd Arnold, Duke Energy's SVP of Smart
Grid and Customer Systems.

The contract calls for Ambient to provide its X-series communications node as
the central communications technology to transmit data from residential and
commercial smart meters, and other applications back to the utility's network
operations center. This communications node allows for the efficient
collection, analysis and management of energy demand through collected usage
data to promote more reliable, affordable and environmentally friendly
operations.

"This contract continues a strong collaboration with Duke Energy from early
smart grid development projects begun in 2005," said John J. Joyce, President
and CEO of Ambient Corporation. "We are pleased to work with Duke Energy to
provide a key component of its communications platform, helping to achieve its
vision for a smart grid network."

Duke Energy, one of the largest electric power companies in the United States,
has committed to building smart grid deployments over the next five years
throughout its service regions, and recently received regulatory approval for
an approximate 700,000 electric smart meter deployment in Ohio. The company
also has plans for smart grid initiatives in Indiana, the Carolinas and
Kentucky. (See Duke Energy's http://smartenergynewsroom.com).
