Ambient Deployment Update
April 30, 2009

Fostering a long relationship with Duke Energy, Ambient Corporation is continuing the support of deployments and pending programs for Duke Energy’s smart grid projects. Ambient’s X2000 communications node, the first to offer cellular connectivity to Duke, is already successfully deployed in Cincinnati, Ohio to cover approximately 50,000 electrical customers and 42,000 gas customers. The Company’s newest communications node, the X-3000, certified for use on Verizon Wireless’ network through their open development program, is deployed in Charlotte, N.C. to initially cover approximately 6,000 electrical customers. The Ambient X-3000 node provides reliable and secure data communications for any IP-based smart grid application such as:

* Advanced metering infrastructure (AMI) - Energy management
* Real-time pricing
* Demand side management (DSM)
* Direct load control
* System monitoring

A robust communications network is the keystone to a modernized electricity distribution grid, which allows for efficient collection, analysis and management of energy data to promote more reliable, affordable and environmentally friendly operations.
