Odyne Corp. Receives Purchase Order from DUECO to Install Propulsion System for Plug-In Hybrid Aeria

The drive system that Odyne is developing for Dueco is designed to minimize fuel use and emissions in a typical aerial truck mission; these vehicles are generally dispatched to a work area and then spend several stationary hours at a site while repair or installation tasks are completed.

Hauppauge, New York - May 30, 2007 - Odyne Corporation (OTCBB:ODYC), a leading developer of advanced plug-in hybrid electric vehicle (PHEV) technology for trucks and buses, today announced that DUECO, Inc., has issued a purchase order to Odyne for installation of Odyne's propulsion technology into an aerial lift truck which will be displayed at the International Construction and Utility Equipment Exposition (ICUEE) on October 16 - 18 in Louisville, Kentucky. Odyne and DUECO had entered into an exclusive agreement earlier this month whereby DUECO and Odyne will develop and install proprietary plug-in hybrid electric vehicle propulsion systems optimized for aerial lift truck applications.

The ICUEE exposition is one of the largest tradeshows in the country and attracts approximately 17,000 industry professionals. The event is unique in that attendees can test the equipment on display, an important part of the decision-making process. There are also over 40 educational sessions at the show where participants can gain insight on the latest developments in the industry.

Odyne's plug-in technology provides much of the energy that is used to operate the truck loads during stationary operation from the power grid. The drive system that Odyne is developing for Dueco is designed to minimize fuel use and emissions in a typical aerial truck mission; these vehicles are generally dispatched to a work area and then spend several stationary hours at a site while repair or installation tasks are completed. In a conventionally powered aerial truck, the engine is idling during this stationary period to provide power for the aerial lift, power tools, lights and other auxiliary loads that are required by the work crew. The Odyne system will provide the fuel efficiency and emission enhancements typical of a hybrid vehicle while the truck is traveling to and from the work site and will allow the engine to be shut off during most of the stationary operation. This results in fuel savings, noise and emission reductions during the work period.

Roger M. Slotkin, CEO of Odyne Corporation, commented, "It's been less than a month since we established a relationship with DUECO and we are excited about installing our propulsion technology into their TL50M material handling bucket truck that will be displayed at the exposition. This affords us the opportunity to feature our technology to a very large audience with an appreciation and need for the solutions Odyne can provide."

Thomas Dalum, CEO of DUECO, stated, "The ICUEE is the perfect forum to feature Odyne's technology on a large scale. By letting the public know that we can offer this cost-effective and environmentally beneficial propulsion system in our vehicles is a win-win situation for both Odyne and DUECO. It is with great anticipation that we await our first vehicle equipped with this technology and we are confident that receptivity to our display vehicle at the show will be very favorable."
