Business Editors

FAIRFIELD, N.J.--(BUSINESS WIRE)--Jan. 29, 2002

Joshua Tree Construction (OTCBB:JSHT) ("Joshua Tree" or the "Company") announces that American Health and Diet Centers, Inc. ("AHDC") dba The Nutritionary ("Nutritionary"), has launched a recently updated website that offers state-of-the-art browsing features, consumer health information, a complete catalog of products and easy ordering through its shopping cart program.

The website resides at www.nutritionary.com.

Joshua Tree has entered into a Letter of Intent to acquire American Health and Diet Centers, Inc. ("AHDC") dba "Vitamin Healthcenters," dba "The Nutritionary." The Company plans to change its name to reflect its new acquisition and change its trading symbol at a later date.

AHDC is a multi-channel marketer of high quality nutraceuticals and natural health product solutions. The Company has developed a low-cost retail store concept that is the core foundation of the model. AHDC gains significant market advantage by selling from high exposure, mall-based, staffed retail locations and small in-line stores. The Company has the ability to increase customer conversion by offering a supplement selection based on specific health solutions. The health solutions address weight loss, energy, sports nutrition, anti-aging and many other areas of concern. The Company offers a direct shipment program that enables customers to order via telephone, Internet or mail. The business model allows for a high margin retail health center that offers consumers convenient multi-channel access to quality products, backed by highly trained personal nutritional counselors. AHDC also developed state-of-the-art point of sale programs and has achieved a superior customer service track record.

Consumers and potential franchisees can now visit the site and find store locations, learn about each health and dietary supplement, join a mailing list for product specials and upcoming newsletters, find out how they can become store franchisees, "Shop the Nutritionary" and locate store locations.

"Our updated website represents a giant step in how consumers can now look for health information including health and dietary supplements," said Nutritionary Chief Operating Officer Marty Reynolds. "It has been shown that 55 million people or 60 percent of the Internet population have used the web to shop. Currently, sales of natural health products on the Internet are experiencing a 72.2 percent growth rate according to the Nutrition Business Journal.

"We have made the Nutritionary site very user friendly and easy to navigate. And what is most important, it allows the website visitor to research our products, make an informed decision and simply and quickly order the products they wish," Reynolds added.

AHDC dba Nutritionary is a multi-channel marketer of high quality nutraceuticals and natural health product solutions. It offers a supplement selection based on specific health solutions.

Because it is a multi-channel marketer, Nutritionary is able to offer a direct shipment program that enables customers to order via telephone, Internet or mail, in addition to its 22 retail stores. The "shop-at-home" concept has been found to augment and even enhance sales that were once only common with face-to-face storefronts.
