Mannatech Declares Dividend

COPPELL, Texas--(Business Wire)--
Mannatech, Incorporated (NASDAQ: MTEX) announced that its Board of
Directors declared a quarterly cash dividend on Tuesday, August 26,
2008 of $0.02 per share of common stock payable on Monday, September
29, 2008, to shareholders of record at the close of business on
Wednesday, September 10, 2008. The dividend is a reduction of $0.07
per share from the dividend paid in the second quarter 2008.

Wayne Badovinus, president and CEO of Mannatech, said, "This marks
the 18th dividend declared by our board since 2004. Reflecting our
lower quarterly sales and recruiting, we believe it is financially
prudent to adjust our dividend downward. Strong liquidity is an
important factor in our on-going turnaround efforts and this action
will make an important contribution. We believe in the quality of our
products and the future of our company, and we remain committed to
returning value to our shareholders."
