NxtPhase To Be Acquired by Beacon Power

VANCOUVER, BC (Apr 25, 2005) – NxtPhase T&D Corporation, a leading provider of digital relays, recorders, and fiber optic solutions for the electric power industry, today announced that it will be acquired by Beacon Power Corporation (Nasdaq: BCON).

NxtPhase will operate as a subsidiary of Beacon Power and will continue to market its relay and recorder and optical sensor product lines under the well-established NxtPhase brand name. Beacon Power is a publicly traded Massachusetts-based company that designs sustainable energy storage and power conversion solutions, including megawatt-level utility grade flywheel-based energy storage systems for frequency regulation and voltage support.

NxtPhase CEO, Andrea Johnston commented, "NxtPhase is moving from being a venture-funded firm to become part of a public company, giving investors an opportunity to be part of a broader company with an array of solutions focused on grid stability and improvement. For our customers, there is added confidence in doing business with a more diversified company with improved capital market access."
"Our customers and OEM partners will not feel any impact from the new ownership arrangement," remarked Tim Leyshock, NxtPhase VP Sales & Marketing. "Over the long term they will benefit from the strength of a larger company focused on their needs as they make improvements to the transmission infrastructure."

The acquisition agreement between Beacon Power and NxtPhase results from introductions made by Perseus, L.L.C. Perseus, NxtPhase and Beacon Power are affiliates of one another. At closing, Beacon will acquire NxtPhase for approximately 15.7 million new common shares of Beacon (subject to adjustment as described in the agreement). Also, immediately after closing, Beacon will grant restricted stock units covering approximately 2.7 million new common shares of Beacon to the NxtPhase employees. As of April 22, 2005, the closing bid price of Beacon Power shares on Nasdaq was $0.84 per share. The acquisition is subject to approval from shareholders and regulatory authorities.

As Beacon Power and NxtPhase proceed with approvals, Perseus has committed to fund NxtPhase with an additional $US 1.5 million of equity financing to ensure stable uninterrupted operations for the company.
