GreenMan Technologies Subsidiary Receives Initial $440,000 International Order for Vehicular Dual Fuel Conversion Systems

CARLISLE, IA--(Marketwire - July 7, 2010) - GreenMan Technologies, Inc. (OTCBB: GMTI) announced that its APG International, Inc. subsidiary ("APGI") has received an order from its local distributor on behalf of Seven-Up Bottling Company PLC ("Seven-Up Bottling"), a soft drink distributor located in Nigeria, for the conversion of approximately 25% of their local delivery truck fleet. The initial order is valued at approximately $440,000 and is expected to be completed by the end of September 2010. Seven-Up Bottling has verbally indicated that upon the successful completion of this initial order they intend to place an order to convert their remaining local delivery truck fleet over a six to nine month period. The estimated value of this potential follow-on order is approximately $1.22 million.

APG's dual fuel system converts existing engines to function more efficiently and at a lower operating cost (fuel costs reduced by 25% to 35%) by seamlessly displacing 40% to 60% of the normal diesel fuel consumption with compressed natural gas ("CNG") or biomethane. In addition, the duel fuel conversion system reduces toxic emissions such as nitrogen oxide (NOX), carbon monoxide (CO) and fine particulate matter as well as enhancing the engine's operating life, since natural gas is a cleaner burning fuel source.

Lyle Jensen, GreenMan's President and Chief Executive Officer, stated, "This order is a reflection of the methodical approach we have implemented for the international market. For the near term, potential customers are requiring a 'demo' of our technology for an initial period of time in order to evaluate the benefits of our dual fuel conversion system prior to purchasing. In the case of Seven-Up Bottling, not only were immediate fuel and maintenance cost reductions realized but the converted trucks were in strong demand among the company's fleet drivers, who noted their improved acceleration and power performance characteristics."

Mr. Jensen added, "As global fleet owners look for an economical way to combat increasing diesel fuel and maintenance costs and comply with more stringent emissions standards, our dual fuel technology represents a sensible and readily available alternative. This order is a validation of the viability of APG's dual fuel technology and illustrates our ability to begin conversion of our large bid pipeline to confirmed orders."
