Greenstone Products Show Initial Market Acceptance

NEW YORK, NY--(Marketwire - January 22, 2008) - Mr. Sal Miwa, CEO of Greenstone Holdings, Inc. (PINKSHEETS: GSHN), announced today that the Company's various products are receiving support in the marketplace resulting in an increase in the Company's revenues. Mr. Miwa noted that although the revenues are modest, they are nevertheless very significant because these are not trial orders, but represent actual production orders, with follow up or repeat orders from companies which have actually used GreenShield™ on the customers' properties, such as homes, decking, outside furniture, and building material such as logs and plywood. Indeed, two test orders have been received from customers, one of which has sizable potential for this year.

Mr. Miwa also reported that the response of customers concerning the quality of Greenstone's products is very, very positive, demonstrating a likelihood of more follow up orders as demand increases, in the slumping housing market. Indeed, Mr. Miwa added that Greenstone is very pleased that customers have found it important to use GreenShield, despite the recent slowdown, predicting that the Company is on track to have a consistent revenue flow, albeit limited, from very satisfied customers.
