Greenman Technologies Announces Name Change

The following is an announcement from , which is based in Lynnfield:

GreenMan Technologies, Inc. (otcqb:GMTI) is pleased to announce that effective August 1, 2012 the Company has changed its name to "American Power Group Corporation." Effective tomorrow, Tuesday August 7, 2012, the Company's common shares will begin trading on the OTCQB under its new ticker symbol "APGI." The name change is a reflection of the Company's refined and enhanced business strategy which began with its acquisition of American Power Group, Inc. (APG) in 2009 and its focus on providing a cost-effective patented Turbocharged Natural Gas(TM) conversion technology for aftermarket vehicular and stationary diesel engines and diesel generators. The shareholders of the Company approved the name change at the annual meeting held July 23, 2012.

Mr. Lyle Jensen, GreenMan's President and Chief Executive Officer, commented, "With our acquisition of American Power Group in July 2009, we shifted our Company focus to the commercialization and marketing of our patented dual fuel technology. Since 2009, we've made great progress both internationally and domestically to increase the use of our dual fuel solution for vehicular and stationary applications and our Company is now one hundred percent dedicated to capitalizing on the growing demand for dual fuel options in the marketplace. With the growth of the APG brand, we thought it made sense to align the corporate name and operations, to enhance our market presence and customer recognition with the goal of continuing to build value for our shareholders."

All future business activity will be undertaken using the new name.
