A Statement from Mannatech.

COPPELL, Texas -- This week Mannatech (Nasdaq:MTEX), a global network marketing provider of nutritional products, reported its tenth consecutive quarter of volume growth with record first quarter sales up 46% from the prior year and earnings per share which were up 55%. Mannatech's high quality proprietary glyconutritional products put it at the forefront of the worldwide boom in sales of nutritional supplements in the U.S. as well as other markets where the company does business including Australia, Japan, Canada, New Zealand, the U.K. and Korea. Nutritional supplements account for sales of $19 billion in the U.S. and are growing about 7% annually, and 150 million Americans take dietary supplements each year.

The direct sales industry has proven to be one of the most dynamic forms of marketing in the world. Direct selling and network marketing comprise a $30 billion business segment in the United States alone, with more than 13 million people engaged in direct selling activities. Furthermore, according to the World Federation of Direct Selling Associations, global sales through direct selling total $92 billion fueled by the efforts of 52 million individuals involved in this type of marketing. The network marketing business model has grown dynamically in popularity and is a leading method for new small-business growth in the U.S. and around the world. Mannatech's dedicated current Associate force of 401,000 grew by more than 52% since the beginning of 2004.

Mannatech's incredible success reflects its professional management team and highly experienced Board of Directors. While it is not unusual for executives and board members of public companies to sell stock from time to time, the proxy statement submitted to the SEC in April 2005 shows that the company's Board and management continue to beneficially own 42% of the company's stock. It should be noted that several Board members have made recent investments in the stock of the company.

Investors can find complete information on insider purchases and sales of Mannatech's stock, litigation, regulatory issues and the background of its executives and board members in the company's filings with the SEC. The company believes it complies with applicable FDA and FTC regulations governing its business and takes action against sales associates who are found to have violated the company's policies concerning advertising and marketing of products. Mannatech has disclosed that it is the subject of pending litigation, although Mannatech strongly denies the allegations and will continue to vigorously defend itself.

Mannatech believes that its products and business model are sound, that its compliance efforts are strong, and that its CEO, management, and Board fully comply with firm codes of ethical conduct. Mannatech intends to continue its focused growth efforts which have resulted in volume increases and outstanding financial results as it prepares to enter new markets in Taiwan, Germany, and Denmark.
