Mannatech to Defend Lawsuits

Mannatech, Inc. (NASDAQ: MTEX) learned yesterday that three additional securities lawsuits have been filed against the Company and some of its officers seeking class action status. The Company has reviewed the allegations in the lawsuits and believes they are without merit. Unfortunately, these types of repetitive lawsuits (seeking class action status) are common in today's litigious society and many reputable companies have successfully defended against similar litigation. The Company believes these new suits are similar to another suit that made essentially the same allegations that was filed in New Mexico earlier this year. That litigation was disclosed in the Company's Form 10Q filed on August 9, 2005, for the period ended June 30, 2005. At that time the Company commented that the initial litigation was also without merit and said it would mount a strong defense.

The Company has retained experienced securities litigation counsel to defend itself and its officers and plans to fight the cases vigorously. The Company believes that litigation is inherently unpredictable; however when faced with several lawsuits making similar allegations, the courts frequently consolidate such cases. It should also be noted that a court must certify the purported class action status for a case to proceed as a class action lawsuit and that the courts have not made such a decision in any of these cases.
