Greenstone Appoints Sheppard Global as Its Exclusive Agent in the Aviation Industry

NEW YORK, NY--(Marketwire - November 1, 2007) - Greenstone Holdings, Inc. (PINKSHEETS: GSHN) announced today that the Company signed an agency agreement with Sheppard Global Ltd. (Sheppard), an international consultancy and technology commercialization company based in Seattle, Washington. Sheppard Global will be representing Greenstone with respect to marketing its metal corrosion sealer, Permeate™ HS-100, to companies in the aviation industry, which management believes will benefit from the cost savings of this new technology.

Mr. Miller Adams, Chief Executive Officer of Sheppard Global and former Director and Vice President in the Phantom Works central Research and development unit of the Boeing Company, stated, "The aviation industry spends substantial amounts of money addressing corrosion control issues. In fact, a government-sponsored study cited by the General Accounting Office estimated the costs of corrosion for military systems and infrastructure at about $20 billion annually. We believe Greenstone Holdings has developed solutions that will prove to be beneficial in various corrosion prevention applications and we are looking forward to introducing this new technology to the aviation industry."

Sal Miwa, Chief Executive Officer of Greenstone Holdings and MIT Master degree Aerospace engineer, said, "Not only am I very happy to be able to get back to my old field but I am also pleased to be able to tap the exclusive network of international relationships of the fine Sheppard Global team."
