NEWS FLASH: One of the greatest resources in the world is trees. They provide beauty and play a vital role in the type of air we breathe. Preserving the wood and other materials we use serves an important purpose as they can be used for years to come. The technology used by Greenstone helps in cost reductions, increases operational efficiencies and helps pave the way for improvements in future product quality improvements. GSHG has emerged as a specialist in building maintenance products and wood treatments.

On February 7th, Greenstone Holdings introduced its chemical product GreenShield™ to the industry, and potential customers at the International Business Show ("IBS") to more than 100,000 building professionals in Orlando, Florida.

Investment Highlights

--  The company was incorporated in Florida in 2000. Now headquartered in
    New York City, Greenstone is continuing to develop high-margin proprietary
    technologies and services
--  GSHG offers a building protection sealer called GreenShield™ BMP
    that protects against mold, termites, moisture, rot, decay, and fire.
Greenstone Holdings has emerged as a new chemical company focused on creating and commercializing products for the building and construction industry with a full range of solutions, including protection from environmental elements such as moisture, water, and even fire. Greenstone's technology is based on its proprietary green technology which is a unique chemical theory developed by leading experts in the field of polymer science. Also called macromolecular science, it is the subfield of materials science concerned with polymers. This technology transforms any material with voids such as wood, paper, and concrete into a composite material. This technology has revolutionized the way we think about products that protect against environmental elements. Greenstone's products are suitable to use with all materials and can be used confidently, knowing that they are safe for the installer, the customer and the general environment. Greenstone's main product, GreenShield™, is a chemical treatment method to protect homes and other buildings from the elements.

Greenstone Holdings is dedicated to continuous improvement of its products and uses the most advanced chemicals that have been tested by various independent parties, including the University of Mississippi for almost 4 years. We believe this company will continue to increase market share in an expanding market. On water damage alone, over $30B is spent annually in the US.

Key Points

Greenstone Holdings is a pioneer in the latest advances in material preservation technology. Because of this, their customers have new, more advanced technologies and a broader portfolio of products with proven performance to meet their needs. Chemicals used to extend the life and usefulness of wood products affects everyone. Durability of woods in homes and buildings is a major concern to every homeowner and builder. Properly treated wood can have 5 to 10 times the service life of untreated wood. This extension of life saves so much money and helps keep us in balance with nature by not cutting down so many trees. The demand for chemically treated wood, paper and concrete will grow from both increasing use on pretreated materials as well as from newly treated materials. Industry analysts forecast that the demand for chemical treatments will increase by at least 50% by 2010. Greenstone offers investors diversification, and now with a host of customized products that we believe will lead to more stable earnings patterns, higher overall profits. The key to investing in this sector, in our opinion, is either diversity or specialization. This company appears to have both, and that is in the company's favor as well as its shareholders.

For patient investors, we think GSHG offers attractive long-term growth potential and share price appreciation. We have established an intermediate-term price target of $0.45, based on today's current share price of $0.12. If this target price can be achieved, and so much relies on the company effectively carrying out its business plan, investors could enjoy a tremendous return. The strength of GSHG is its management team, whose track record is increasing sales. Development of its mission statement and the values of these individuals should spark solid growth, steady improvement on its existing product base and increasing shareholder value. There is little doubt that this is a rapidly growing sector.
