ITEM 1. SECURITY AND ISSUER
This Amendment No. 1 ("Amendment") relates to the common stock, par
value $0.0001 per share (the "Stock"), of Mannatech, Incorporated, a Texas
corporation (the "Company"), which has its principal executive offices at 600
South Royal Lane, Suite 200, Coppell, TX, 75019. This Amendment amends that
certain Schedule 13D filed with the Securities and Exchange Commission on
October 29, 1999 by the following persons: Samuel L. Caster, an individual
("Mr. Caster"), William C. Fioretti, an individual ("Mr. W. Fioretti"), The
Fioretti Family Partnership, Ltd., a Texas limited partnership (the "Fioretti
Partnership"), Charles E. Fioretti, an individual ("Mr. C. Fioretti"), Donald
W. Herndon, an individual ("Mr. Herndon") Harley Reginald McDaniel, Sr.,
M.D., an individual ("Dr. McDaniel"), Dick Hankins, Jr., an individual ("Mr.
Hankins"), Nancy Hankins, an individual ("Mrs. Hankins"), and Marlin Ray
Robbins, Jr., an individual ("Mr. Robbins"). Each of the persons or entities
(other than the Company) named in the previous sentence is referred to herein
individually as a "Reporting Person" and collectively as the "Reporting
Persons."
Item 4 is hereby amended to read in its entirety as follows:
ITEM 4. PURPOSE OF TRANSACTION
The Reporting Persons are filing this Amendment to report that no
Reporting Person has any current intention to act together with any other
Reporting Person for the purpose of acquiring, holding or disposing of any
Stock. Accordingly, it is the Reporting Persons' belief that no Reporting
Person is currently a member of a "group" within the meaning of Section
13(d)(3) of the Securities Exchange Act of 1934.
Depending upon the market price thereof and upon other conditions,
certain Reporting Persons may acquire additional Stock from time to time in
the open market or otherwise. In addition, depending upon market prices and
other conditions, certain Reporting Persons may dispose of some or all of
their Stock at any time and from time to time in the open market or otherwise
at prices which such Reporting Persons may determine.
Item 5 is hereby amended to read in its entirety as follows:
ITEM 5. INTEREST IN SECURITIES OF ISSUER
(a) The responses to Items 2 through 11 on the cover pages hereto

November 12, 1999).
(b) Mr. Hankins and Mrs. Hankins share voting and dispositive
power with respect to their shares of Stock reported on this Amendment. Mr.
W. Fioretti, as the general partner of the Fioretti Partnership, may be
deemed to share with the Fioretti Partnership voting

and dispositive power with respect to the Fioretti Partnership's shares of
Stock reported on this Amendment. Except as set forth in this Item 5(b),
