NEWS RELEASE

COPPELL, Texas, Apr 15, 2011 (BUSINESS WIRE) --

Mannatech, Incorporated (NASDAQ: MTEX) has received information regarding the status of Marlin Ray Robbins' shares of the Company's common stock pledged by him. Marlin Ray Robbins is a member of the Mannatech Board of Directors.

In 2005, Mr. Robbins pledged 1.4 million of his shares of Mannatech common stock to Triangle Equities, which has since been placed in receivership along with related entities, as a result of an action filed by the U.S. Securities and Exchange Commission (SEC). The SEC and the receiver allege Triangle Equities was part of a fraudulent stock-based loan scheme in which it would fraudulently liquidate stock pledged by borrowers such as Mr. Robbins. In a related matter, Triangle Equities Director Michael Spillan was recently indicted for securities violations as a result of such loan program.

Given a recent court filing by the receiver proposing to resolve the outstanding claims of the borrowers, including Mr. Robbins, against Triangle Equities, it appears unlikely that Triangle Equities still holds the shares or that Mr. Robbins will regain possession of the shares which were pledged to Triangle Equities. The allegations of the receiver will be heard by the court in the receivership on June 28, 2011.

"Mr. Robbins continues as a significant Mannatech shareholder, to act as a great spokesperson for Mannatech, build his Mannatech business, and act as a mentor to all independent Associates," said Co-CEO and Chief Financial Officer Steve Fenstermacher. "His dedication to our company, social entrepreneurship and integrative health will be instrumental to Mannatech's current business as well as our continuing expansion into new markets, along with his leadership for all independent Associates intent upon making a difference in our world."
