Ambient Closes $2.5 Million Private Placement

Enabling Smart Grid Efficiencies Remains Company’s Focus for 2008

Boston, MA, January 16, 2008 - Ambient Corporation (OTCBB: ABTG), a leader in power line communications technologies and platforms, today announced that it has closed on a private placement of $2.5 million in principal amount of its newly issued 8% Senior Secured three-year Convertible Note from the institutional investor in Ambient’s 2007 fundings.

The Company issued the secured Note, which requires no repayment of principal until the October 2010 maturity date, to Vicis Capital Master Fund LLC. Interest on the Note does not begin accruing until July 2008; with the first quarterly interest payment due in September 2008. This latest investment increases the total investment by Vicis to $12.5MM.

Ambient has used portions of proceeds from previous closings to successfully pay down the remainder of its debt incurred from a funding entered into in 2006. In eliminating the remainder of its short-term debt, Ambient’s next repayment of principal debt is not required until the October 2010 maturity date referenced above.

John J. Joyce, President and CEO of Ambient, commented, “Having the support of an investor who shares and supports our long-term commercial vision is essential for Ambient’s success. Ambient is on track to continue with our initiatives, and reach important milestones we have set for the next phase of our growth.”
