Greenstone Appoints an Applicator Distributor

NEW YORK, NY--(Marketwire - November 13, 2007) - Greenstone Holdings, Inc. (PINKSHEETS: GSHN) announced today that the Company recently signed a memorandum of understanding ("MOU") with En-Viroguard Inc. of Sweetwater, Tennessee to distribute Greenstone's chemical product, GreenShield™. En-Viroguard, in the interim, has begun marketing GreenShield through its first applicator, Green Team, while the parties finalize the details of a formal agreement. Since GreenShield protects wood material from moisture and water damage, which is especially important to the construction of log homes, En-Viroguard has begun its efforts by focusing on the log home market; selling GreenShield to applicators who spray the product on customers' homes that are still under construction. According to the Log Home Living Institute, there are approximately 500,000 existing log homes and 27,000 new log homes being built every year.

To date, Green Team has sprayed two log homes, achieving very favorable results. The cost, including labor, to the home owner for a GreenShield application has been $.90 per square foot of surface area being treated. A typical size, 2,000 square foot log home, was treated with GreenShield, applied to the exterior walls and decks, for approximately $5,500. The application required 14 gallons of GreenShield.

John Fulcher, Chief Executive Officer of Green Team, said, "My father and I have been in the log home building business for many years, but we have never seen any protective chemical really work like GreenShield. It is so easy to apply and effective. We love it. The homeowner who witnessed the application loved it which is even more important."

Robert Rhyne, Chief Executive Officer of En-Viroguard, said, "After looking at Green Team's results, I am extremely confident that we can quickly expand an applicator network across our territory from Florida to Michigan."
