Item 5.  Other Events

     On June 4, 2001, Mr. Charles E. Fioretti resigned as the Chairman of the
Board and as an employee of Mannatech. Mr. Fioretti will however, continue to
serve as a director on Mannatech's Board of Directors. On June 4, 2001, the
Board of Directors accepted Mr. Fioretti's resignation and as a result,
Mannatech entered into a Separation Agreement and Full and Final Release  (the
"Separation Agreement") with Mr. Fioretti. Under the terms of the Separation
Agreement, Mannatech agreed to pay Mr. Fioretti $600,000 on June 11, 2001 and
June 4, 2002, respectively. In addition, on June 4, 2001, Mr. Fioretti will sell
50,000 shares of his common stock to Mannatech at a price of $1.45 per share,
which was the closing price on June 4, 2001. The Lock-up Agreement dated August
8, 2000 with Mr. Fioretti will continue; however, the terms of the Renewal and
Extension Promissory Note with Mr. Fioretti dated February 17, 1999 will be
modified to continue to accrue interest at 6.0%, with the remaining principal of
$127,121.47 plus accrued interest due the earlier of (i) February 17, 2011 or
(ii) thirteen days after the date in which Mr. Fioretti no longer owns at least
100,000 shares of Mannatech's common stock.
