February 2, 2010

Stuart, Florida – Feb 2, 2010 – Calnetix Power Solutions (“CPS”), a premier manufacturer of green, energy efficient waste heat recovery systems for renewable and distributed energy markets, today announced it has sold its TA100 microturbine product line to Capstone Turbine Corporation (Nasdaq: CPST).

Capstone and CPS also entered into a three-year Original Equipment Manufacturer agreement under which CPS will supply its new, innovative, 125kW waste heat recovery generator system. In exchange for certain minimum purchase requirements, Capstone will have exclusive rights to sell the zero emission waste heat generator for all microturbine applications and for applications below 500kW where the source of heat is the exhaust of a reciprocating engine used in a landfill application.

Under the purchase agreement, CPS sold substantially all of the rights and assets related to the manufacture and sale of its TA100 100kW microturbine generator. Under a separate agreement CPS and Capstone also entered into a manufacturing sub-contract arrangement under which CPS will continue to manufacture the TA100 turbines for Capstone from existing CPS TA100 backlog and select new orders received.

“CPS is extremely pleased to enter this long term strategic relationship with Capstone and to move from a competitive relationship to a collaborative one. By doing so we will leverage the combined companies microturbine and waste heat recovery technologies,” stated Brad Garner President of CPS. “The ability for both companies to work together to grow top line revenue without either adding significant additional operating costs should improve the profitability of both companies,” added Garner. “CPS is looking forward to leveraging the existing Capstone worldwide distribution channel and well known brand to quickly grow the market acceptance of our new waste heat recovery generator.”

“The CPS TA100 microturbine is most similar to the Capstone product design when compared to other products in the industry and the 100kW rating fits nicely between our 65kW and 200kW product offerings,” stated Darren Jamison, Capstone’s President and Chief Executive Officer. “By acquiring the CPS TA100 product we not only strengthen Capstone’s suite of microturbine products but also add approximately 24 more distributors and business partners bringing Capstone’s total number of distributors and partners to over 90 worldwide,” added Jamison.
