Boston-Power(R) Fuels Next Stage of Growth With One of the Largest Portable Power Venture Investments

WESTBOROUGH, MA--(Marketwire - January 3, 2008) - Boston-Power, Inc.®, a rapidly growing provider of first-to-market portable power solutions, today announced $45 million in new funding. The Series C round was led by Oak Investment Partners and included existing blue-chip investors Venrock Associates, Granite Global Ventures and Gabriel Venture Partners.

With $8.4 billion in committed capital, Oak Investment Partners is one of the world's leading venture capital firms. As part of its investment, Oak Investment Partners Managing Partner Bandel Carano has joined Boston-Power's board of directors. To date, Boston-Power has raised more than $68 million in funding.

Boston-Power will use the new capital to scale business development, marketing, research and development, and manufacturing operations to meet strong global demand for Sonata -- the company's next-generation Lithium-ion battery technology. Sonata initially targets notebook computers. Eventually, the company's products could be used to power an extensive range of end-applications -- from consumer electronics devices to hybrid electric vehicles.

Boston-Power also announced today a manufacturing partnership with GP Batteries. (See press release: "Boston-Power Selects GP Batteries to Expand Manufacturing of Next-Generation Sonata Notebook Computer Battery.") GP Batteries is the number one battery manufacturer in Asia outside Japan and the tenth largest battery manufacturer in the world.

"The Lithium-ion battery industry is undergoing a major technology advance -- one that will provide substantially better safety, dramatically improved cycle life and extremely fast recharge," said Oak Investment Partners Managing Partner Bandel Carano. "Boston-Power is leading this next generation. Initially delivering breakthrough performance for laptop computers, the company's technology promises to be equally compelling for a range of other applications, including hybrid and all-electric vehicles."

"Now that we're shipping product, our success is largely driven by our ability to implement well on a fast-growing, multibillion dollar market opportunity," said Boston-Power Founder and CEO Dr. Christina Lampe-Onnerud. "Oak's keen insights and proven ability to guide companies to success make them an excellent addition to our team."

Unprecedented Demand for Notebook Computer Batteries

Demand for safe, high-performance, environmentally responsible Lithium-ion notebook computer batteries is substantial. IDC reported 37 percent growth worldwide in portable PC shipments in the third quarter of 2007, the fastest in more than a decade. This exceeded growth in desktop PCs by 33 percent in the same quarter. Moreover, Gartner reported that third quarter notebook computer shipments surpassed desktop PC shipments, at 52 percent.

Sonata redefines the portable power space by establishing new benchmarks in safety, cycle life, performance and environmental sustainability. Initially targeting notebook computers, Sonata delivers the longest cycle life ever available from any Lithium-ion battery. That translates to longer and more usable power -- like-new performance for three years versus current batteries that start to fade in three to six months. Sonata's "drop-in" design enables it to be used with existing notebook computers -- requiring no design changes on the part of notebook computer original equipment manufacturers (OEMs) such as HP.

Boston-Power's Technology: Establishing a New Benchmark in Portable Power

Boston-Power's patent-pending, whole-system approach means its technology can be applied to a vast range of end-applications. As a result, total cost of ownership benefits inherent in its notebook computer batteries prove increasingly impressive in cases where even greater power is required.

Complementing best-in-class performance, the unmatched safety benefits available from Boston-Power's technology apply whether used in notebook computers and consumer electronics devices or other applications such as hybrid electric vehicles (HEVs). With existing notebook computer batteries containing roughly the same power as hand grenades -- and HEV batteries representing far greater than that -- Boston-Power's proactive, preventative safety features overcome the issues challenging current Lithium-ion batteries.

Leadership Team Ready for Rapid Growth

On related matters, Boston-Power welcomes two executives to its management team. Declan Shalvey has assumed the role of chief operating officer. He brings to his new position more than 20 years of experience in operations, manufacturing, supply chain management, customer service, and contract and price negotiation for start-ups and multinationals throughout the U.S., Asia and Europe. Robert Andersen has joined as chief financial officer, following 30 years of executive-level financial leadership with companies that include Raytheon Corporation, United Technologies Corporation, Digital Equipment and Idera Pharmaceuticals. Additionally, Granite Global Ventures Managing Partner Scott Bonham now fills the board seat previously held by fellow GGV Managing Partner Thomas Ng.
