Boothroyd Dewhurst Sells Corporate License for DFMA Software to Plug Power Inc.; Expanded use of Design for Manufacture and Assembly software will help standardize the company's practices in product cost analysis.

WAKEFIELD, R.I. -- Boothroyd Dewhurst, Inc., developers of Design for Manufacture and Assembly (DFMA(R)) software, today announced that Plug Power Inc., headquartered in Latham, N.Y. (NASDAQ: PLUG), has purchased a corporate license for DFMA software.

DFMA software helps engineering supply chains identify the major cost drivers associated with manufacturing and assembling parts and supports the development of innovative designs that are economical to produce. Plug Power, a leader in providing clean, reliable on-site energy, will use the software to improve the manufacturability of its fuel cell products and to obtain estimates of product costs early in the design cycle.

"We evaluated a number of cost-estimating packages over an 18-month period and decided to expand our use of Boothroyd Dewhurst DFMA software," says Joe Mueller, Advanced Manufacturing Engineering Manager for Plug Power. "We expect that implementing a standardized DFMA process across the company will help our engineering team reduce product part counts and manufacturing assembly time and provide us with a cost-estimating reference tool during negotiations with our suppliers."

Plug Power presently uses DFMA software for its GenCore(R) and GenSys(R) product lines. Companywide rollout of the software is expected to be complete mid-2006.

About DFMA(R) Software

DFMA consists of complementary Design for Assembly (DFA) and Design for Manufacture (DFM) software. Engineers use DFA software to reduce the cost of a product by consolidating parts into elegant and multifunctional designs. DFM Concurrent Costing software then helps engineers quickly judge the cost of producing the individual components of the new design. Used together, DFM and DFA software give engineers an early cost profile of product designs, providing a basis for planning and decision making. When performed in the earliest stages of concept design, DFMA analysis has the potential to dramatically reduce manufacturing and other product life-cycle costs before they are locked in. DFMA software operates in Microsoft(R) Windows 98, Windows 2000, and Windows XP.
