COPPELL, Texas -- January 9, 2014

Mannatech, Incorporated  (NASDAQ: MTEX), the founder of the M5M^SM (Mission 5
Million^SM) social entrepreneurial movement, the pioneer of glycobiology and
the leading innovator of naturally-sourced supplements based on Real Food
Technology^® solutions, is proud to share that Direct Selling News magazine
has featured CEO and Chief Science Officer, Dr. Robert Sinnott, in its Top
Desk section of its January issue. The article is titled “The Science of
Business.”

Over his tenure at Mannatech, Dr. Sinnott has applied much of his formal
training in the sciences, combined with his career experiences in industry and
government, to develop and manage the company’s innovative product line. As
CEO, he has applied many of these scientific disciplines in many other areas
of the business as well. As quoted in the article, Dr. Sinnott says that,
ideally, good business leaders and good scientists both possess creativity,
intuition, innovation and the ability toanalyze data and spot trends.

In the article, he looks at business from a scientifically objective
viewpoint, discussing how many scientific concepts apply well to the direct
selling business model.

Dr. Sinnott shares numerous comparisons in the article such as how today’s
businesses are comprised of highly specialized areas, similar to the structure
of a cell. He also connects psychological and environmental factors in
business to factors that govern natural selection in the wild. Additionally,
he observes how the principles of money flow in economics are similar to how
energy flows in thermodynamics.

Another concept he touches on is synergy. Dr. Sinnott believes that
sustainable situations are completely possible where the business, customers
and society can benefit through properly structured relationships, as is
demonstrated by Mannatech's business model of social entrepreneurship.

“Mannatech has done very well working the fertile ground where science and
business converge,” said Dr. Sinnott. This is manifested in the company’s
large patent portfolio of flagship products, in its Mission 5 Million (M5M)
program and in the launch of its revolutionary Ūth™ Skin Rejuvenation Crème
last year. In fact, he says, “Direct selling and network marketing business
models are particularly rich with potential synergies just waiting to be
tapped.”

Direct Selling News Magazine has been serving the direct selling and network
marketing executive since 2004. The full article can be found here.
