2. Company Description Legal Status and Business Activities: PSW-Energiesysteme GmbH was founded on 13 th December 2007 in Celle, Germany. The areas of business are the development, production and sales of environmentally friendly and highly efficient decentral energy systems of the following types; small wind energy, co- generation systems and heat pumps. Various engineering services are also offered. PSW employs 10 members of staff in all areas of the business. Four additional temporary staff are employed in production. The production of nearly all components and assemblies for the entire EN-Drive® 2000 small wind turbine and its accessories is carried out in-house at PSW (quota of approx. 80%). In comparison to competitor manufacturers, this leads to a very high added-value of these PSW products. Founding Partners: Dr. Hartwig Schwieger, Celle, Germany John Piper B.Sc. Ag.

Market Sector / Products Heat and Power Generation for Private Customers private homes and properties Heat and Power Generation for the Commercial Sector farms and gricultural businesses hotels, restaurants, etc. manufacturing companies trading firms and service providers PSW Product Range EN-Drive® small wind turbines (sector: wind energy ) EN-Maxx® heat pump systems (sector: efficient heating) EN-Power® micro co-generation (sector: combined heating and power generation) 6

7. Innovation and New Design Concepts EN-Drive® Small Wind Turbine Multifunctional Use of Wind Power: The mechanical power of the rotor is transmitted to the bottom of the tower where the rotational energy can be used for many different purposes: electricity generation – on-grid electricity generation – off-grid (export business) heating using wind power and an electrical heat pump heating using wind power and a mechanically driven heat pump (in base of tower) various customer uses: water pumping, compressed air, mechanical drives, etc. Electricity Generation: On-grid electricity generation (for own-consumption and feeding into the grid) 7

8. EN-Drive® 2000 Series Small Wind Turbine The EN-Drive® small wind turbine is a highly efficient, multifunctional turbine which provides environmentally friendly energy and an alternative drive-system for different customer needs: Environmentally friendly electricity production for own-consumption (and feeding into the grid) and independance from future price increases for electricity Multiple international patent applications to protect PSWs interlectual rights CE-conforming product including state of the art engineering and design High quality Made in Germany product reasures customers of reliability and a safe investment Simple installation due to inteligent design and ready-for-use on delivery concept Fast and easy installation and maintenance with easy to use hydraulic raising system 8
