CARLISLE, IA--(Marketwire - August 25, 2009) - GreenMan Technologies, Inc. (OTCBB: GMTI) today announced its subsidiary, National Playground Compliance Group ("NPCG"), has entered into an exclusive business development agreement with the Oklahoma State School Boards Association ("OSSBA").

Lyle Jensen, GreenMan's Chief Executive Officer stated, "Our agreement with OSSBA is our fifth exclusive state school board endorsement agreement, adding to our existing exclusive agreements in California, Iowa, Minnesota and Missouri. Our goal as we enter fiscal 2010 is to add several new 'warm weather' states which should allow us to mitigate some of the seasonality we experience during the colder months of the year."

Tim Mahoney, NPCG's President, stated, "With the recent re-authorization of the Americans with Disabilities ('ADA') Act, school boards are embracing NPCG's compliance program and offerings in anticipation of expanded funding for special education and a continued strong commitment to build new facilities with green technology. NPCG's role will be to assist state schools, school board associations, parent groups and state's Department of Education with their playground regulation, product and compliance requirements. We look forward to a successful partnership with OSSBA and assisting Oklahoma schools in deploying safe, accessible and green playgrounds for their school children."

"We are excited to partner with NPCG for this program," added Dr. Jeff Mills, OSSBA's Executive Director. "The OSSBA will work exclusively with NPCG to help school districts improve safety, accessibility and fitness opportunities for our children and we expect this partnership will be a valuable asset for our schools." Dr. Mills added, "OSSBA and NPCG will formally launch the 'Oklahoma Playground Compliance Program' at OSSBA's annual state wide conference and exposition, August 28-30, 2009 at the Cox Center in Oklahoma City."
