Item 1. Business

General

  Mannatech, Incorporated, a Texas corporation, develops and sells proprietary
nutritional supplements and topical products through a network marketing
system. We sell our products in the United States, Canada, Australia and the
United Kingdom through a network of approximately 269,000 active associates as
of March 9, 2000 compared to approximately 237,000 active associates as of
February 28, 1999. An "active" associate is one who has purchased products
within the last 12 months. We plan to expand into Japan in the summer of 2000,
while continuing to assess the potential and risks of expansion into other
foreign markets.

  Since beginning operations in November 1993, we have achieved year-to-year
growth in net sales, from approximately $8.4 million in 1994 to approximately
$179.7 million in 1999. The net increase is primarily due to our introduction
of new products and expansion into other geographical markets through three of
our wholly-owned subsidiaries, which are currently operating. The subsidiaries
are as follows:

  .  Mannatech Australia Pty Limited was formed in April 1998 and began
     operations in Australia on October 1, 1998 as a limited service
     provider.

  .  Mannatech Ltd. was formed in April 1999 and began operations in the
     United Kingdom on November 15, 1999 as a limited service provider.

  .  Internet Health Group, Inc., a Texas corporation, was formed in May 1999
     and began operations on December 20, 1999 marketing its proprietary
     products, specially developed nutritional supplements and sports
     nutrition products over the Internet, through its website at
     www.clickwell.com.

  On February 12, 1999, we completed our initial public offering. In the
initial public offering, we and certain selling shareholders sold an aggregate
of 3,056,016 shares of our common stock, par value $0.0001 per share, at a
price of $8.00 per share. Of the total number of shares sold in the initial
public offering, 1,500,000 were sold by Mannatech yielding net proceeds to
Mannatech of approximately $9.2 million. The remaining 1,556,016 shares of
common stock were sold by certain shareholders of Mannatech. The net proceeds
to the selling shareholders were approximately $12.0 million. Since the
initial public offering, our common stock has traded on the Nasdaq National
Market under the symbol "MTEX."

  We are principally engaged in a single business segment, the development and
distribution of nutritional supplements and topical products. Information for
each of our most recent three fiscal years, with respect to the amounts of
revenues from sales, operating profit and identifiable assets of this segment
is set forth under Item 6 of this report on page 20.

  We pursue a two-fold business strategy:

  .  to develop a proprietary line of nutritional supplements having both
     health benefits and mass appeal to a general population demanding non-
     toxic healthcare alternatives; and

  .  to provide an appealing framework for persons interested in our products
     to establish a direct sales business.

  To date, we have focused our development efforts primarily in the area of
carbohydrate technology, creating a proprietary ingredient, Ambrotose(R)
complex, which combines certain naturally occurring sugars required to support
optimal cell-to-cell communication. We have also focused on developing
products based on scientific advances in the emerging field of phytochemistry.
This field has identified certain naturally occurring components of various
plants, known as "phytochemicals," which, while not essential to sustain life,
are believed fundamental for optimal health.


                                       1


  Ambrotose(R) complex is the cornerstone of our proprietary product lines.
These products are designed to support various systems and functions of the
human body, including:

  .  the cell-to-cell communication system;

  .  the immune system;

  .  the endocrine system;

  .  the intestinal system; and

  .  the dermal system.

  We also market products designed to aid in sports performance and
nutritional support.

  Our products are marketed exclusively through a network marketing system. We
believe that the network marketing system is well-suited to our products,
which emphasize health and nutrition, because network marketing allows in-
person product education not available through traditional marketing
techniques. The network marketing system appeals to a broad cross-section of
people, particularly those seeking to supplement family income, start a home-
based business or pursue employment opportunities other than conventional,
full-time employment.

  Our principal executive offices are located at 600 S. Royal Lane, Suite 200,
Coppell, Texas 75019, our telephone number is (972) 471-7400 and our website
address is www.mannatech-inc.com. Unless the context otherwise requires, the
term "Company," "our" or "we," as used in this report shall mean Mannatech,
Incorporated and its subsidiaries, collectively.

Industry Overview

  The nutritional supplements industry includes manufacturers and distributors
of products that are generally intended to enhance the body's performance and
well being. Nutritional supplements include:

  .  vitamins;

  .  minerals;

  .  dietary supplements;

  .  herbs;

  .  botanicals; and

  .  compounds derived from the above.

  The nutritional supplements industry has experienced substantial growth
since the adoption of the Dietary Supplement Health and Education Act of 1994.
This act has allowed vendors of dietary supplements to educate consumers
regarding the effects of certain ingredients. According to the Nutrition
Business Journal Annual Industry Overview, 1997 dietary supplement sales in
the United States increased by 13% over 1996 and totaled approximately $12.6
billion. With respect to the United Kingdom, the October/November 1998
Nutrition Business Journal noted that 1997 European dietary supplement sales
were approximately $11.9 billion, of which 12% was derived from sales in the
nutrition industry. Further, with respect to our planned expansion into Japan,
the October/November 1998 Nutrition Business Journal noted that Japanese
dietary supplements sales were approximately $6.4 billion in 1997, of which
54% was derived from sales in the nutrition industry. We believe the growth in
the nutritional supplement market is driven by several factors, including:

  .  the general public's heightened awareness and understanding of the
     connection between diet and health;

  .  the aging population, particularly the baby-boomer generation, which is
     more likely to consume nutritional supplements;

                                       2


  .  product introductions in response to new scientific research; and

  .  a nationwide trend toward preventive medicine.

  Nutritional supplements are sold primarily through:

  .  mass market retailers, including mass merchandisers, drug stores,
     supermarkets and discount stores;

  .  health food stores;

  .  mail order companies; and

  .  direct sales organizations.

  In the past decade, direct selling has grown as a means to distribute
products due to advancements in technology and communications. Network
marketing is a type of direct selling that has also grown significantly in
recent years. According to the "Survey of Attitudes toward Direct Selling,"
prepared by Wirthlin Worldwide, food, nutrition and wellness products are
among the three categories experiencing the greatest gains in the direct
selling industry since 1976. According to this survey, approximately 50% of
the American public have purchased products or services from a direct selling
company at some point in their lifetime. In addition, approximately 40% of
adult Americans have expressed an interest in direct selling as a method of
buying products and services. Further and estimated 23% of those who have
never purchased products and services from direct selling companies are
interested in direct selling. We believe we are positioned to capitalize on
the trends of growth in direct sales and demand for nutritional supplement
products.

Operating Strengths

  We attribute much of our success to our two-fold business strategy, which
is:

  .  to develop a line of nutritional supplements having both health benefits
     and mass appeal to the increasing number of people who are becoming more
     health conscious; and

  .  to provide an opportunity for people interested in our products to
     establish a direct sales business.

  We believe this business strategy will enable us to continue our growth by
capitalizing on the following strengths:

  Proprietary Products. We offer an innovative line of products based upon our
proprietary, patent-pending research. We believe that the discovery and
development of products containing certain carbohydrates necessary to optimum
health represents an expanding business opportunity for us. We recognized the
nutritional need for the eight known monosaccharides in supporting optimal
health and developed and filed a patent application on a compound containing
these monosaccharides called Ambrotose(R) complex. We believe that maintaining
a proprietary line of products containing this compound is important for two
reasons: (A) it is a marketing factor that differentiates us from our
competitors; and (B) the limited availability helps to drive demand and
enables premium pricing.

  Research and Development. We believe that our experienced personnel and
research and development facilities built in 1998 will allow us to develop and
market additional new proprietary products. Our research and development
efforts are led by two scientists with an aggregate of over 35 years of
experience designing products based on carbohydrate technology. Our
technologically advanced laboratory is equipped with gas and liquid
chromatographs and mass spectrometers, which will be used to:

  .  maintain quality standards;

  .  support our research and development commitment in the area of new
     herbal complexes; and

  .  support our development of both new and existing products.


                                       3


  To complement our in-house staff and facilities, we have sought, and will
continue to seek, strategic alliances with several large manufacturers of
nutritional supplements. These companies work with us to create, develop and
manufacture our proprietary products. We also work with other smaller
companies to identify and develop new innovative products.

  Associate Support Philosophy. We are committed to providing the highest
level of support services to our associates. We believe that we meet the needs
of, and build loyalty with, our associates through our highly personalized and
responsive customer service. We sponsor four to six associate events
throughout the year to provide education and motivation for thousands of
associates. These events offer information, aid in business development and
are a venue for associates to interact with our leading distributors and
researchers.

  Flexible Operating Strategy. Flexibility is a key part of our existing and
ongoing success. We outsource our production and form strategic alliances to
minimize capital expenditure where practicable. We believe we can enter
international markets in an efficient and cost-effective manner by using the
expertise and resources of our strategic allies in the areas of distribution
and logistics, call center operations, product registration and export
requirements. Information technology also plays an essential role in our
operating expansion into new markets. By developing this operating strategy,
we believe we can reduce the operational problems typically encountered by
network marketing companies.

  Experience and Depth of our Management Team. Our management team consists of
experienced individuals drawn from a variety of backgrounds and having
expertise in various fields, including:

  .  product research and development;

  .  marketing;

  .  direct sales;

  .  legal and compliance;

  .  information technology; and

  .  product distribution.

  All principal managers have substantial business experience, most with
larger businesses. These managers are able to bring the perspective of
traditional business to our network marketing system. Our management team's
goal is to provide a sound, systematic and reliable framework within which
each associate can fit his or her personal style of conducting business.

Growth Strategy

  Our primary growth strategy is to:

  .  increase associate product sales;

  .  continue to expand operations in existing markets;

  .  expand into newly identified markets; and

  .  continue to evaluate expansion into additional foreign markets.

  We believe that our future growth will be based on the following factors:

  Introduce New Products. Since our inception, we have and currently intend to
continue to introduce new products each year. We expect each new product to
contain one or more proprietary components and to complement existing
products.

  Attract and Retain New Associates and Enhance Associate Productivity. Since
we began operations, we have enjoyed significant growth in the number of
associates by focusing on our operating strengths and creating

                                       4


a business climate that recognizes associates for their achievements. We plan
to continue to introduce new associate achievement levels in part to encourage
greater retention, motivation and productivity. In addition, we will continue
to modify our associate events and recognition programs to encourage retention
and growth in the number of associates. No one associate accounts for more
than 10% of our total sales.

  Enter New Markets. We believe that potential for growth exists in
international markets based upon our experience over the past year and reports
from our competitors. In April 1996, we began selling to associates in Canada.
In October 1998, we opened our Australian headquarters in St. Leonards,
Australia. In November 1999, we opened our United Kingdom headquarters in
Basingstoke, Hampshire. We are also planning to open our Japanese headquarters
in Tokyo, Japan during the summer of 2000. We will continue to research the
potential of other foreign markets. By employing our flexible operating
strategy in the international sector, we believe we will be able to enter new
markets in a cost-effective and efficient manner. We will base our decision to
expand into new markets on (A) size of the market, (B) anticipated demand and
(C) ease of entry.

Products and Product Development

  We market a line of quality, proprietary products, including twenty-six
different nutritional products and three topical products. We believe our
focused product line contributes to efficient distribution and inventory
management. We also offer a variety of sales aids, including enrollment and
renewal packs, brochures, videotapes and even develop a personalized website
for our associates. These sales aids accounted for approximately 24.7%, 18.9%
and 17.6% of our net sales in 1997, 1998 and 1999, respectively.

  We believe that the discovery and use of certain carbohydrates offers
significant potential for nutritional benefits. Healthy bodies, comprised of
many sophisticated components working together, must have an accurate internal
communication to function at an optimal level. In its most basic form, this
communication occurs at the cellular level and is referred to by molecular
biologists as cell-to-cell communication. To maintain a healthy body, cells
must "talk" to other cells. Scientists have learned that certain molecules
found on the surface of all cells, called "glycoproteins,' play an essential
role in all cell-to-cell communication. The name "glycoprotein" is derived
from the molecules' composition: sugar, known as "glyco," and protein. The
body's need for these carbohydrates is important because up to 85% of
glycoproteins are composed of specific monosaccharides that we believe are
necessary to support optimal health.

  Harper's Biochemistry, a leading biochemistry reference source, lists eight
monosaccharides commonly found in human glycoproteins, which are important to
the healthy functioning of cell-to-cell communications in the human body.
These monosaccharides are:

  .  fucose;

  .  galactose;

  .  glucose;

  .  mannose;

  .  N-acetylgalactosamine;

  .  N-acetylglucosamine;

  .  N-acetylneuraminic acid; and

  .  xylose.

  From the universe of approximately 200 monosaccharides found in nature, our
proprietary ingredient, Ambrotose(R) complex, is designed to provide
monosaccharides, which are necessary for optimal cell-to-cell communication.

  Our overall product strategy is to develop proprietary nutritional
supplements that capitalize on existing and emerging scientific knowledge and
the growing worldwide interest in alternative healthcare and optimal health.

                                       5


We focus on bringing new proprietary and, where possible, patentable products
to market that can be developed into new product lines, while expanding our
existing product lines. We incurred research and development costs related to
specific clinical studies, quality assurance programs and new product
development of approximately $381,000, $391,000 and $438,000 in 1997, 1998 and
1999, respectively. We also incurred research and development costs related to
designing new products, enhancing existing products, Food and Drug
Administration compliance studies, general supplies, internal salaries and
consulting fees of approximately $3,008,000, $3,365,000 and $3,623,000 in
1997, 1998 and 1999, respectively.

  We introduced the following new products in 1999:

  .  Bulk Ambrotose in a 75-gram canister;

  .  A new flavor of the MannaBAR(TM), vanilla-coated yogurt apple crunch.
     Like the other MannaBARs, this bar still contains the equivalent of the
     recommended minimum daily supply of Ambrotose(R) complex, Phyt.Aloe(R)
     and Plus; and

  .  GlycoLEAN(TM) Lean Body System, a complete lifestyle system for fighting
     fat composed of five unique products to help achieve and manage weight.
     The five products are GlycoLEAN(TM) Accelerator, GlycoLEAN(TM) Catalyst,
     GlycoLEAN(TM) Fiber Full, GlycoLEAN(TM) Manager and GlycoSLIM(TM) Drink
     mix (three flavors--chocolate, vanilla or strawberry).

  In addition, we plan to release additional products as new nutritional
compounds or areas of consumer demand are identified. All new products are
expected to contain our proprietary components. Our product launches typically
occur at our corporate events. We will base our selection of products
developed on:

  .  the marketability and proprietary nature of the product;

                                       6


  .  regulatory considerations;

  .  the availability of ingredients; and

  .  the existence of data supporting claims of functionality.

  To support, validate and monitor the proprietary nature of our products, our
research and development department conducts appropriate research both before
and after product launches and continuously throughout the year by taking
samples directly from shipments received from our manufacturers.

  The following chart indicates the year we introduced our products:

Product Distribution System

  Overview. The foundation of our sales philosophy and distribution system is
network marketing. We believe network marketing systems is an effective
vehicle to distribute our products for the following reasons:

  .  it is easier to explain the benefits of our products in a person-to-
     person, educational setting;

  .  it is more direct and personal than television and print advertisements;

  .  direct sales allow potential consumers to actually test our products;

  .  there is greater impact on the consumer from associate and consumer
     testimonials;

  .  it assists in building a base of potential consumers for additional
     products;

  .  associates can provide higher levels of customer service and attention
     by following up on sales to ensure proper product usage and customer
     satisfaction; and

  .  associates' contact with customers generates repeat purchases.

  We encourage, but do not require, associates to use our products, nor do we
require a person to be an associate in order to purchase our products. We
believe our network marketing system is particularly attractive to prospective
associates for the following reasons:

  .  the potential for supplemental income;

  .  no requirement to purchase inventory;

  .  no need to collect money from customers;

  .  very little paperwork involved in our sales process; and

  .  a flexible work schedule.

                                       7


  We suggest associates enroll new associates with whom the associates have
relationships; family members; friends; business associates; neighbors; or
otherwise. We believe that associates will be more likely to remain with us if
they are enrolled by someone with whom they have an ongoing relationship.

  Associates pay for products prior to shipment. We carry no accounts
receivable from our associates, except for minor amounts owed to us for check
returns or other exceptions. Associates generally pay for products by credit
card; however, a small portion of orders are paid in cash or with money orders
and checks. Associates may automatically order products on a continuous basis
and receive a discount. Automatic orders accounted for approximately 36.9%,
44.9% and 47.1% of net sales for the years ended December 31, 1997, 1998 and
1999, respectively.

  Advances in communications, including telecommunications and the Internet,
and the increasing use of videotape players, fax machines and personal
computers have enhanced the effectiveness of direct selling as a distribution
channel in the past decade. We produce high-quality video and audio tapes for
use in product education, demonstrations and sponsoring sessions. In March
2000, we substantially completed our science-based website,
www.GlycoScience.com that allows users to search for science-based information
about various nutritional supplements, some of which are found in our
products. We believe that these sales aids play an important role in the
success of associate efforts. We are committed to using current and future
technological advances to enhance the effectiveness of the direct selling
efforts of our associates.

  Associate Development. We believe the key contributing factors to our long-
term growth and success are the recruitment of new associates and retention of
existing associates. We are active in the development of associates, including
in the areas of recruitment, support, motivation and compensation.

  We primarily rely on existing associates to enroll new associates. The
enrollment of new associates creates multiple levels in the network marketing
structure. These new associates are referred to as "downline" or "sponsored"
associates. Associates can purchase products directly from us at wholesale
prices and can sponsor other associates in order to build a network of
associates and product users.

  We also rely heavily on existing associates to train new associates. Our
Master Associate training course, an advanced training program for associates,
was developed using both the expertise of experienced corporate trainers and
the experience of seasoned associates. While we provide brochures, magazines
and other sales materials, advanced training is specially designed to provide
systematic and uniform training to associates about us and our products,
compensation plan, and methods of doing business.

  The needs of our associates are a priority and we believe that providing a
high level of support for our associates' efforts has been and will continue
to be important to our success. We provide a large number of support services
tailored to the needs of our associates, including:

  .  motivational meetings;

  .  educational and informative conference calls;

  .  automated fax services;

  .  an efficient ordering and distribution system;

  .  personalized customer service via telephone, Internet and e-mail;

  .  24-hour, seven days per week access to information through touch-tone
     phones and the Internet;

  .  a liberal product return policy;

  .  a current database of each associates' downline information;

  .  business development materials that we believe will increase product
     sales and recruitment; and

  .  an innovative website database, www.GlycoScience.com that was
     substantially completed in March 2000 and designed to provide a user
     with the ability to search and provide science-based information about
     nutritional supplements, some of which are included in our products.

                                       8


  We currently recognize associate performance with four levels of associate
leadership achievement:

  .  Regional;

  .  National;

  .  Executive; and

  .  Presidential.

  The level of associate leadership is based upon the associates' downline
growth and commissionable sales. Commissionable sales are sales of products
with assigned product point volume. Generally, sales aids are not assigned any
product point volume. Each leadership level provides the opportunity for
compensation, excluding the generation bonus discussed below, ranging from 15%
of commissionable sales at the Regional director level to 9% of commissionable
sales at the Presidential level. In addition, associates are eligible for a
"generation bonus," which is an additional achievement level specially
designed to motivate sales and downline growth. The additional achievement
levels are available to the associates once the associate has achieved
Presidential leadership status. The associate can then achieve four levels of
Presidential status:

  .  Bronze;

  .  Silver;

  .  Gold; and

  .  Platinum.

  Each of these achievement levels provides associates with the opportunity
for additional compensation. We intend to continue to expand our program for
associate recognition as necessary in the future to reward increased levels of
performance and to further motivate our associates.

  Associate Compensation. Our plan combines the aspects of two widely used
multilevel marketing compensation plan concepts. Our plan pays commissions
based on (A) a percentage of the associate's commissionable sales; and (B) the
attainment of certain associate leadership levels. These elements of our
compensation plan are similar to other multilevel marketing compensation
plans. In addition, our associates, at their discretion, determine their
resale price of products purchased from us at the wholesale price. Our
compensation plan pays the associate as follows:

  .  A bonus or commission for qualified associates ranging in amounts from
     $20.00 to $180.00 earned based on downline growth and commissionable
     product sales.

  .  Associates who have completed advanced training and are at the all star
     level can receive $25.00 for each eligible associate they train.

  .  Bonuses or commissions ranging in amounts from $10.00 to $200.00 are
     also earned on products included in starter or renewal packs sold.

  .  The "fast start" bonus, ranging in amount from $100.00 to $500.00, is
     paid if a new associate obtains Regional or National level within three
     months of initially signing up as an associate.

  .  The "car incentive" bonus, ranging in amounts from $200.00 up to
     $700.00, is paid to associates, who have achieved certain sales levels
     and who have increased their product sales by 10% from the previous
     year's sales volume.

  .  Various other bonus programs were also introduced during the year
     allowing, among other things, our associates to earn various trips
     including trips to our newly-opened international corporate offices.

  Our compensation plan attempts to compensate both associates in the early
stages of building their business as well as associates with more established
organizations by rewarding associates for breadth as well as depth in their
downline organizations.

                                       9


  Based upon our knowledge of other industry-related network marketing
compensation plans, we believe that our compensation plan is among the most
financially rewarding plans offered in the industry. Historically, commissions
as a percentage of net sales have been 41.0%, 40.4% and 40.9% for 1997, 1998
and 1999, respectively.

  We do not employ the compensation plan described above outside of the United
States and Canada. In the international sector, we use a similar plan with
regard to commissionable product sales, but each plan is tailored to fit the
laws and considerations governing compensation of associates in each country.
We have integrated our international compensation plan across all markets in
which our products are, or will be, sold, thereby allowing associates to
receive commissions for global product sales, rather than merely local product
sales. We refer to this as our "global seamless downline structure" and we
hope it will continue to allow our associates to build global networks by
creating downlines in our expanding international markets. Associates will not
be required to establish new downlines or requalify for higher levels of
commissions within each new country in which they begin to operate. Our
international compensation plan is designed to pay approximately the same
percentage compensation as in the United States and Canada. We believe our
international compensation plan has and will continue to stimulate both
product sales and the development of width and breadth in downline
organizations.

  Management of Associates. We take an active role in the management of our
associates. Many multilevel marketing companies encounter difficulties with
regulatory authorities due to lack of oversight of associate activities. Any
oversight process is complicated because our associates are independent
contractors and not legally employees of Mannatech. However, we seek to
restrict the statements and conduct of associates regarding our business by
contractually binding associates to abide by our associate policies and
procedures. Each associate receives a copy of the policies and procedures that
must be followed in order to maintain the associate's status with us.
Associates are expressly forbidden from making any representation as to the
possible earnings of any associate, other than through statements of Mannatech
indicating the range of actual earnings by all associates. We also monitor
associate websites for content on a regular and continuing basis. In March
1999, we introduced Mannapages(TM), a personal Internet website program
established for our associates, whereby for a $49.00 fee, we produce an
Internet website for the associate. Mannapages(TM) assists us not only in
monitoring associate websites on a regular basis, but also helps to increase
associates' sales efforts. We currently anticipate that we will replace all
associate websites with Mannapages(TM) by the end of 2000.

  We have established, and enforced as much as possible, a compliance program
for disciplining associates who do not comply with our policies and
procedures. We have developed formal steps for proceeding if a complaint is
filed against an associate. Our primary goal is to educate the associate to
ensure that he or she understands the policy or procedure in question and will
follow all of our policies and procedures in the future. Also, our compliance
and legal departments, in cooperation with other departments, regularly
evaluate associate conduct and the need for new and revised policy making. We
believe our compliance program reflects positively on us, helps in the
maintenance of associate ethics and aids in our recruiting activities.

  Product Return Policy. Our product return policy provides that retail
customers may return the unused portion of any product to the selling
associate and receive a full cash refund. Any associate who provides a refund
to a customer is reimbursed with product by us if they provide proper
documentation and ship us the remainder of the product. Our product return
policy for associates is to refund 90% of the wholesale cost for any returned,
unopened, restockable products and any up-to-date corporate literature that is
in good, usable condition. Historically, product returns have not been
significant. Returns as a percentage of net sales were 1.5%, 1.7% and 1.0% in
1997, 1998 and 1999, respectively.

Information Technology and Systems

  We believe that maintaining sophisticated and reliable transaction
processing systems is essential to our long-term success. Our systems are
designed to:

  .  reduce the time required to supply an associate or customer with our
     products;

  .  provide detailed and customized billing information;

                                      10


  .  respond quickly to associate needs and information requests;

  .  provide detailed and accurate information concerning qualification and
     downline activity;

  .  provide detailed reports of commissions paid to the associate;

  .  support our customer service department; and

  .  monitor, analyze and report financial and operating trends.

  During 2000, we expect to spend approximately $8.6 million on information
technology operations and development activities, of which approximately, $3.6
million will be for capital expenditures. These expenditures relate to
providing new technology advances to continue to meet the above needs and
expand transaction-processing systems to accommodate our expected
international growth. We believe that our significant investment in software,
hardware and personnel will enable us to:

  .  respond rapidly to our business needs for information technology
     assessment and development;

  .  manage international growth and our seamless downline structure; and

  .  reduce expenses as a percentage of net sales.

  Our suppliers of computer hardware are Dell Computer Corporation, Hewlett-
Packard Company, Compaq Computer Corporation, and Digital Equipment
Corporation. Digital Equipment Corporation's hardware systems are linked to
provide a high level of availability for critical business applications. We
believe the global presence of these suppliers will be an important factor in
supporting our continuing expansion plans.

  Our financial software was upgraded at the end of 1996 with the acquisition
of a sophisticated financial system capable of operating on several platforms.
We also purchased a report writing system, which interfaces with our financial
systems. In the summer of 1999, we upgraded our current financial software to
a Microsoft Windows-based platform. These systems, used together, enable us to
track and analyze financial information and operations, as well as create and
produce custom reports.

Production and Distribution

  All of our products are manufactured by outside contractors, providing us
with the production capacity necessary to respond to fluctuations in sales and
limiting our investment in capital equipment. We believe that we currently
have in place the manufacturers necessary to meet our inventory requirements
over the next several years, including continuing expansion into foreign
markets. Nonetheless, we continue to identify new quality-driven manufacturers
to supply the products necessary for our success. We also seek to save money
by periodically reviewing pricing considerations and by requiring competitive
bids from various manufacturers meeting our quality and performance
requirements.

  We currently acquire our ingredients solely from superior suppliers of such
ingredients. We have also identified dependable alternative sources for all of
our ingredients except Manapol(R) and arabinogalactan, which are components of
Ambrotose(R) complex. With these alternative sources, we could produce or
replace these ingredients if we cannot purchase ingredients from our current
suppliers. In January 2000, we signed a new supply agreement with our
exclusive supplier of Manapol(R). The supply agreement will require us to buy
a minimum monthly volume at an agreed-upon price through August 2002. We
eventually plan to bring the blending of all proprietary formulas in-house,
further protecting the confidential nature and quality standards of our
proprietary formulations.

  In January 1998, our Texas distribution operation relocated to our $1.3
million, 75,000 square foot leased warehouse facility in Coppell, Texas. The
facility includes an automated system capable of processing 18,000 orders per
day. This system has enhanced our productivity and supported sales volume
growth. The distribution facility contains a warehouse, distribution offices
and an ingredient mixing area that is currently not being

                                      11


utilized. We also have contract distribution facilities in Canada, Australia,
the United Kingdom and Roanoke, Texas. For further information on these
contract facilities see "Properties" on page 17.

Government Regulations

  To regulation of our direct selling activities, we are also controlled by a
large number of laws, governmental regulations, administrative determinations,
court decisions and similar legal requirements at the federal, state and local
levels in both our United States and foreign markets. These regulations
address, among other things:

  .  our network marketing system;

  .  transfer pricing and similar regulations affecting the amount of foreign
     taxes and customs duties we pay;

  .  taxation of associates, requiring us to collect taxes and maintain
     appropriate records;

  .  how we make, package, label, distribute, import, sell and store our
     products;

  .  what we put in our products;

  .  what we claim our products do for the human body;

  .  how we advertise; and

  .  the degree in which we are liable for associates' claims about our
     products.

  Products. The following governmental agencies regulate some aspect of our
business or our products:

  .  the Food and Drug Administration;

  .  the Federal Trade Commission;

  .  the Consumer Product Safety Commission;

  .  the Department of Agriculture;

  .  the Environmental Protection Agency;

  .  the Postal Service; and

  .  various agencies of the states, localities and foreign countries in
     which our products are manufactured, distributed and sold.

  The Food and Drug Administration regulates the formulation, manufacture,
packaging, storage, labeling, promotion, distribution and sale of the foods,
dietary supplements and over-the-counter drugs distributed by us. Food and
Drug Administration regulations require both our suppliers and us to meet good
manufacturing practice regulations for the preparation, packing and storage of
our products. The Food and Drug Administration has published a Notice of
Advanced Rule Making for good manufacturing practices for dietary supplements.
The Food and Drug Administration has also issued a final rule on January 6,
2000. The rule is called "Statements made for Dietary Supplements Concerning
the Effect of the Product on the Structure or Function of the Body." We
believe this final rule will not adversely effect us as we believe we are
already in compliance with this rule.

  The Dietary Supplement Health and Education Act of 1994 revised the
provisions of the Federal Food, Drug and Cosmetic Act concerning the
composition and labeling of dietary supplements. We believe this act is
generally favorable to the dietary supplement industry. The legislation
creates a new class, by statute, of "dietary supplements." This new class
includes vitamins, minerals, herbs, amino acids and other dietary substances
for human use to supplement the diet. This legislation grandfathers, with
certain limitations, dietary ingredients that were on the market before
October 15, 1994. A dietary supplement, which contains a dietary ingredient
that was not on the market before October 15, 1994, must provide evidence
establishing that the supplement is reasonably

                                      12


expected to be safe. Manufacturers of dietary supplements which make a
"statement of nutritional support," thereby describing certain types of
product performance characteristics, must:

  .  have evidence that the statement is truthful and not misleading;

  .  make a disclaimer in the statement itself; and

  .  notify the Food and Drug Administration of the statement no later than
     30 days after the statement is first made.

  The majority of the products that we market are classified as dietary
supplements under the Federal Food, Drug and Cosmetic Act. In September 1997,
the Food and Drug Administration issued regulations governing the labeling and
marketing of dietary supplement products. These regulations cover:

  .  the identification of dietary supplements and their nutrition and
     ingredient labeling;

  .  the wording used for claims about nutrients, health claims and
     statements of nutritional support;

  .  labeling requirements for dietary supplements for which "high potency"
     and "anti-oxidant" claims are made;

  .  notification procedures for statements on dietary supplements; and

  .  premarket notification procedures for new dietary ingredients in dietary
     supplements.

  The notification procedures became effective in October 1997. The new
labeling requirements became effective on March 23, 1999; however, we had
already revised our product labels as necessary to reflect the new
requirements. We believe we comply with these requirements. In addition, we
are required to continue our ongoing program of providing evidence for our
product performance claims, and notify the Food and Drug Administration of
certain types of performance claims made for our products. Our substantiation
program involves compiling and reviewing the scientific literature pertinent
to the ingredients contained in our products.

  In certain markets, including the United States, claims made with respect to
dietary supplements, personal care or any of our other products may change the
regulatory status of our products. For example, in the United States, the Food
and Drug Administration could possibly take the position that claims made for
some of our products make those products new drugs requiring preliminary
approval. The Food and Drug Administration could also place those products
within the scope of a Food and Drug Administration over-the-counter drug
monograph. Over-the-counter monographs dictate permissible ingredients,
appropriate labeling language and require the marketer or supplier of the
products to register and file annual drug listing information with the Food
and Drug Administration. Emprizone(R) is the only product we sell that is
labeled as an over-the-counter monograph drug. If the Food and Drug
Administration asserts that our product claims cause them to be considered new
drugs or fall within the scope of over-the-counter monographs, we would be
required to either file a new drug application, comply with the applicable
monographs or change the claims made in connection with our products.

  Additionally, dietary supplements are subject to the Nutrition, Labeling and
Education Act, which regulates health claims, ingredient labeling and nutrient
content claims characterizing the level of a nutrient in a product. This act
prohibits the use of any health claim for dietary supplements unless the
health claim is supported by significant scientific agreement and is pre-
approved by the Food and Drug Administration.

  We may be required to obtain an approval, license or certification from a
foreign country's ministry of health or comparable agency prior to entering a
new foreign market. We work with local authorities in order to obtain the
requisite approvals, license or certification before entering a foreign
market. The approval process generally requires us to present each of our
products and product ingredients to appropriate regulators and, in some
instances, arrange for testing of our products by local technicians for
ingredient analysis. Such approvals may be conditioned on reformulation of our
products or may be unavailable with respect to certain of our products or

                                      13


certain ingredients contained in our products. We must also comply with
product labeling and packaging regulations that are different from country to
country. In markets where a formal approval license or certification is not
required, we will rely upon the advice of local counsel, in each country, to
help us ensure we comply with the law.

  The Federal Trade Commission regulates the marketing practices and
advertising of all our products. In the past several years, the Federal Trade
Commission instituted enforcement actions against several dietary supplement
companies for false and misleading marketing practices and advertising of
certain products. These enforcement actions have resulted in consent decrees
and monetary payments by the companies involved. The Federal Trade Commission
has increased its review of the use of the type of testimonials we use in our
business. The Federal Trade Commission requires reasonable evidence proving
product claims at the time that such claims are first made. The failure to
have this evidence when product claims are first made violates the Federal
Trade Commission Act. Although the Federal Trade Commission has never
threatened an enforcement action against us for the advertising of our
products, there can be no assurance that the Federal Trade Commission will not
question our advertising or other operations in the future.

  We cannot predict the content of any future laws, regulations,
interpretations or applications. We also cannot predict the future impact of
the different governmental regulations; however, any or all of such
requirements could be a burden and costly, to us. Future regulations could,
however:

  .  require us to change the way we conduct business;

  .  require us to change the contents of our products;

  .  make us keep additional records;

  .  make us increase the available documentation of the properties of our
     products; or

  .  make us increase or use different labeling and scientific proof of
     product ingredients, safety or usefulness.

  Network Marketing System. Our network marketing system, which includes our
compensation plan, is controlled by a number of federal and state statutes and
regulations, and is administered by the Federal Trade Commission and various
state authorities. The legal requirements controlling network marketing
organizations are in part directed to make certain that product sales are
ultimately made to consumers. In addition, achievement within these
organizations must be based on sales of products rather than compensation from
the recruitment of additional associates, investments in the organizations or
other non-retail sales related criteria. For instance, various markets limit
how much associates may earn from commission on sales of associates who were
not directly sponsored by the associate. We have and will continue to obtain
regulatory approval of our network marketing system in jurisdictions that
require such approval. If regulatory approval is not required, we will rely on
the advice of counsel to ensure our regulatory compliance.

  We signed a consent decree in February 1997 as a result of negotiation with
the Attorney General of the State of Michigan where we agreed to monitor
product purchases by our associates in Michigan. The purpose of the monitoring
is to identify and correct any instances of coerced sales. To continue
monitoring we also conduct random audits, of associates in Michigan, for
evidence of stockpiling. To date, we have found no evidence of coerced sales
or stockpiling by our associates in Michigan. Further, our associate policies
and procedures are designed to provide no incentive or reward to an associate
for engaging in such activities. Recently, we were contacted by the Michigan
Attorney General's office and asked to provide data maintained under the
consent decree, because of the contents contained in the Associates' self-
generated literature. We were also asked to tell them what measures we are
taking to address the associate's conduct, and what measures we would
implement in order to prevent future associate conduct in violation of the
consent decree. We believe we have complied with this request.

  In Canada, our network marketing system is regulated by both national and
provincial law. Under Canada's Federal Competition Act, we must make sure that
any representations relating to associate compensation made

                                      14


to prospective associates constitute fair, reasonable and timely disclosure
and that they meet other legal requirements of the Federal Competition Act.
Our compensation plan has been reviewed and a positive opinion was received
from the appropriate Canadian authorities. All Canadian provinces and
territories other than Ontario have legislation requiring that we register or
license as a direct seller within that province. Licensing is designed to
maintain the standards of the direct selling industry and to protect the
consumer. Some provinces require that both Mannatech and our associates be
licensed. We believe we hold the required provincial or territorial direct
sellers' licenses.

  In Australia, our network marketing system is subject to both federal and
state regulation. Our compensation plan in Australia is designed to meet state
requirements and the requirements of Australia's Trade Practices Act. Our
business and trade practices and our associates are regulated by state law and
the Trade Practices Act. Claims and representations relating to our products
are regulated by both the Trade Practices Act and Australia's Therapeutic
Goods Act.

  In the United Kingdom, our network marketing system is subject to national
regulations. Our compensation plan in the United Kingdom is designed to meet
national requirements, the requirements of the Fair Trading Act of 1973 and
the Trading Schemes Regulations 1997. Our business and trade practices and our
associates are regulated by the Direct Selling Association Code of Business
Conduct and the U.K. Codes of Advertising and Sales Promotion. Claims and
representations relating to our products are regulated by the Trading
Standards Office.

  Other Regulations. We are also subject to a variety of other regulations in
various foreign markets, including:

  .  social security assessments and taxes;

  .  value added taxes;

  .  goods and services taxes;

  .  sales taxes;

  .  customs duties;

  .  employee/independent contractor regulations;

  .  employment and severance pay requirements;

  .  import/export regulations; and

  .  antitrust laws.

  For example, in many markets we are restricted in the amounts and types of
rules and termination criteria that we can contractually impose on our
associates. If we do not comply with these restrictions, we may be required to
pay social security or other tax or tax-type assessments on behalf of our
associates and we may incur severance obligations to terminate the associate.
In some countries, we may be subject to such taxes or payment requirements in
any event.

  In some countries, including the United States, we may also be governed by
regulations concerning the activities of our associates. In some countries, we
are, or regulators may find that we are responsible for our associates'
conduct. Regulators may request or require that we take steps to make certain
that our associates comply with these regulations. The types of conduct
governed by regulations include, in part:

  .  claims made about our products;

  .  promises or claims of income by us or our associates; and

  .  sales of products in markets where the products have not been approved,
     licensed or legally allowed for sale.

                                      15


  In some markets, including the United States, improper product claims by our
associates could cause our products to be reviewed or re-reviewed by
regulatory authorities. This kind of review could result in our products being
classified or placed into another category with stricter regulations or
requiring labeling changes.

  Compliance Procedures. To comply with the many regulations that apply to our
business, we have developed formal compliance measures, including our
associate disciplinary procedures and internal policies for compliance with
Food and Drug Administration and Federal Trade Commission rules and
regulations.

  We conduct research into applicable foreign laws and regulations before
entering any new international market. We also continue to research laws
governing associate conduct and revise or alter our business system,
compensation plans, associate requirements and other materials and programs as
required by laws and regulations in each market. We attempt to educate
associates about acceptable business conduct in each market through our
policies, procedures, manuals, seminars and other training materials and
programs. We are able to perform only limited monitoring procedures to make
certain that our associates comply with existing policies, procedures and
regulations, and that they do not distribute our products in countries where
we have not commenced operations. We cannot promise that all our associates
comply with all existing policies, procedures and regulations.

Competition

  The nutritional supplements industry is large and intensely competitive. We
compete directly with companies that manufacture and market nutritional
products in each of our product lines, including:

  .  Rexall Showcase International;

  .  Rexall Sundown, Inc.;

  .  Solgar Vitamin and Herb Company, Inc.;

  .  Nu Skin Enterprises, Inc.;

  .  Twinlab Corporation; and

  .  Weider Nutrition International, Inc.

  Nutritional supplements are offered for sale in a wide-variety of ways.
While we believe that consumers appreciate the convenience of ordering
products from home through a sales person or the Internet, the buying habits
of many consumers who have purchase products through traditional retail
methods are difficult to change. The number of our products in each product
category is also relatively small compared to the wide variety of products
offered by many other nutritional product companies.

  We also compete for new associates with other retail, multilevel marketing
and direct selling companies in the nutritional supplements industry. Many of
our competitors and other direct selling organizations have longer operating
histories, are better known and have greater financial resources. These
competitors include:

  .  Amway Corporation;

  .  Nu Skin Enterprises, Inc.;

  .  Body Wise International, Inc.;

  .  ENVION International;

  .  Herbalife International, Inc.;

  .  Enrich International;

  .  Rexall Showcase International;

  .  Rexall Sundown, Inc.;

  .  Forever Living Products, Inc.; and

  .  Melaleuca, Inc.

                                      16


  We compete for new associates by stressing the ease of our delivery system,
the superiority of our compensation plans and our proprietary and quality
products. We believe that many more direct selling organizations will enter
the market as the number of direct sellers expands over the next several
years. Because the pool of individuals interested in direct selling is limited
in each market, the potential pool of associates for our products is reduced
when other network marketing companies successfully recruit these people into
their businesses.

Employees

  As of December 31, 1999, we employed 310 people in the United States, 16 of
whom occupy executive positions; 14 people in Australia; 12 people in the
United Kingdom and 1 person in Japan. This number does not include our
associates, who are independent contractors and not employees of Mannatech.
Our employees are not unionized and we believe we have a good relationship
with our employees.

Item 2. Properties

  We lease property at several locations for our headquarters and distribution
facilities, including:



                                                                  Expiration

  Our United States distribution facility is capable of filling 18,000 orders
per day and is currently operating at 34% of its full capacity. We also have
several contract distribution center operations. We believe all of these
leased facilities are adequate for our current operations in the immediate
future. Our contract distribution center operations are as follows:



                                                               Orders   Current

Item 3. Legal Proceedings

  In October 1997, we filed an objection to the issuance of a registered
trademark being issued to IntraCell Nutrition, Inc., which had filed a
trademark application for the name, "Manna." In our objection, we state that,
among other things, "Manna" is a general descriptive term often applied to
nutritional products, and is for that reason not entitled to trademark
protection. Discovery was completed in this case and briefs were filed. The
case is now pending an oral hearing before the Trademark Trial and Appeal
Board of the United States Patent and Trademark Office. We believe that we
have a substantial likelihood of prevailing in our objection to the granting
of the tradename.

  In March 1998, Johnnie Hill d/b/a Taylor Enterprises, one of our associates,
filed a lawsuit in the 44th Judicial District Court, Dallas County, Texas,
alleging that we breached the contract with Mr. Hill as an associate. Mr. Hill
further alleged that we committed fraud, conversion, conspiracy and that we
failed to properly account

                                      17


for the payments owed to him. In May 1998, the suit was ordered into
arbitration by the District Court. In March 1999, Mr. Hill filed an
arbitration claim with the American Arbitration Association in Dallas, Texas,
alleging that we breached our contract with him, interfered with his business
relationships, did not pay him money owed to him, committed fraud and damaged
him in the amount of $5.0 million. We filed a counterclaim against Mr. Hill
for $79,750, which is the alleged amount fraudulently diverted and that
asserted the alleged damages by Mr. Hill were artificially inflated and not
related to the actual performance of Mr. Hill's associate position. In
December 1999, the American Arbitration Association issued an award of
arbitrators, which resulted in an estimated credit to us of approximately
$6,000. Subsequently, Mr. Hill asked for reconsideration by the arbitrators,
which was denied by the arbitration panel.

  On August 20, 1999, we initiated a legal action in the United States
District Court for the Northern District of Texas against Dr. Daryl See
alleging among other things, that he misled Mannatech when he claimed that one
of his studies, which Mannatech used to illustrate the positive effects of our
products, had been funded by the National Institutes of Health and conducted
under auspices of the University of California-Irvine.

Item 4. Submission of Matters to a Vote of Security Holders

  On October 20, 1999, shareholders controlling 74.5% of the voting stock of
Mannatech, acting by written consent, amended our Bylaws in order to:

  .  allow our shareholders to set the size of the board; however, the board
     of directors must have a minimum of three directors;

  .  revise the procedures for call, notice and administration of board
     meetings;

  .  revise the duties of the Chairman of the Board to include presiding over
     and determining the order of business at board meetings;

  .  revise the procedures for amending certain Bylaws provisions adopted by
     our shareholders;

  .  allow special meetings of the board to be called by the President, or by
     any two other directors acting together; however, 24-hour notice must be
     given for these meetings, which notice may, under some circumstances be
     waived; and

  .  provide that only board members may attend board meetings and that
     directors are not allowed to have personal legal counsel present, unless
     allowed by a majority vote of the directors.

  In the written consent, the shareholders also approved the expansion of the
board from five to seven members and elected Mr. James M. Doyle, Jr., as a
Class III director with his term expiring in 2002. This information was filed
November 3, 1999, on a preliminary information statement on Form Pre 14C (file
No. 000-24657) reporting the shareholder consent with the Commission.

  On November 19, 1999, the board appointed Mr. Anthony E. Canale to replace
and complete the term of Mr. Patrick D. Cobb, a Class I director whose term
expires in 2000 and had resigned from the board. The board also elected Mr.
Terry L. Persinger, as a Class III director whose term will expire in 2002.

                                      18


                                    PART II

Item 5. Market for Registrant's Common Equity and Related Shareholder Matters

  Market for our Common Stock. On February 12, 1999, we completed our initial
public offering and on February 16, 1999, our common stock began trading on
the Nasdaq National Market under the symbol "MTEX." As of March 24, 2000 the
total number of outstanding shares of our common stock was 24,939,293 and the
closing price on such date was $4.688. Pricing information prior to February
16, 1999 is not available, because our common stock was not publicly traded
prior to that date. Set forth below are the high and low closing sales prices
of our common stock as reported on the Nasdaq National Market for each quarter
of the fiscal year ended December 31, 1999:



                                                                 High     Low
                                                                ------- -------
                                                                  
First Quarter (from February 16, 1999)......................... $31 3/4 $10 1/2
Second Quarter................................................. $23 7/8 $10 1/8
Third Quarter.................................................. $13 5/8 $6 9/16
Fourth Quarter................................................. $ 8 7/8 $ 4 5/8


  Holders. As of March 24, 2000, there were approximately 5,218 shareholders
of record of our common stock.

  Dividends. Our shareholders received dividends totaling approximately
$9,936,882 and $1,326,104 in 1998 and 1999, respectively. We do not intend to
pay any dividends in 2000; however, our board of directors intends, from time-
to-time, to reevaluate this policy based on our consolidated results of
operations, financial condition, cash requirements and other factors deemed
relevant. Any future payments of dividends will be subject the discretion of
our board of directors and subject to certain limitations under the Texas
Business Corporation Act.

  Sales of Unregistered Securities.

  None.

  Uses of Proceeds from Registered Securities. On February 12, 1999, we
completed our initial public offering. In the initial public offering, we and
certain shareholders sold an aggregate of 3,056,016 shares of our common
stock, par value $0.0001 per share, at a price of $8.00 per share. None of
such payments were direct or indirect payments to directors, officers,
affiliates or 10% beneficial owners of Mannatech. No underwriter was involved
in the initial public offering.

  Of the total number of shares sold in the initial public offering, 1,556,016
shares of common stock were sold by certain shareholders of Mannatech at a
price of $8.00 per share, yielding gross proceeds, of $12,448,128. The net
proceeds to the selling shareholders were $11,950,203, after deducting the
placement agent's fee of approximately $497,925.

  The remaining 1,500,000 shares sold in the initial public offering were sold
by Mannatech at a price of $8.00 per share, yielding gross proceeds to
Mannatech of $12 million. The net proceeds were $9,240,958, after deducting:

  .  deferred offering costs of approximately $1,963,431;

  .  legal, accounting, printing and other costs of approximately $406,385;
     and

  .  the placement agent's fee of $389,226, net of reimbursement of $90,774
     in expenses by the placement agent.

                                      19


  We intend to use our net proceeds of $9.2 million as follows:

  .  $6,265,858 of the net proceeds is intended to fund our international
     expansion. As of December 31, 1999, we had used $4,445,200 of these
     proceeds to pay for our expansion to Australia, the United Kingdom, and
     begin our expansion into Japan. We have $1,820,658 of the net proceeds
     remaining for future international expansion.

  .  $2,975,100 of the net proceeds was used, as planned, to fund our current
     working capital needs.

Item 7. Management's Discussion and Analysis of Financial Condition and
Results of Operations

  You should read the following discussion and analysis of our financial
condition and results of operations in conjunction with the Consolidated
Financial Statements and related notes in Item 14 of this report, beginning on
page F-1. Unless we state otherwise, all financial information presented
below, throughout this report and in the Consolidated Financial Statements and
related notes includes Mannatech and all of our subsidiaries on a consolidated
basis.

Overview

  Since beginning operations in November 1993, we have achieved year-to-year
growth in overall net sales. Our growth is mainly attributable to (A) our
introduction of new products; (B) growth in the number of associates; and (C)
expansion into new international markets. In the future, as we expand into
additional international markets, we expect international operations to
account for an increasing percentage of our consolidated net sales. As a
result, in 1998 and 1999, which marked the beginning of our expansion
internationally, our growth rate in net sales generated in the United States
began to shrink as compared to prior years and in 1999, for the first time,
Canadian net sales actually decreased slightly in both sales dollars and as a
percentage of net sales. However, the growth rate of net sales generated in
Australia increased and continues to exceed our expectations. Furthermore, in
November 1999, we opened our United Kingdom operation. We expect these trends
to continue as we continue to expand internationally. We have also noticed
similar trends from some of our competitors, who have expanded
internationally. Net sales (in millions and as a percentage of consolidated
net sales) by country for the three years ended December 31, 1999 were as
follows:



                                     United                             United
   Year                              States      Canada    Australia   Kingdom
   ----                           ------------ ----------- ---------- ----------
                                                    
   1997.......................... $127.9 84.9% $22.7 15.1% $ --  -- % $ --  -- %
   1998.......................... $135.9 82.5% $26.8 16.1% $ 2.2 1.4% $ --  -- %
   1999.......................... $137.9 76.7% $25.7 14.3% $15.8 8.8% $ 0.3 0.2%


  The basic earnings per share of $0.45 for the year ended December 31, 1999
remained the same for the year ended December 31, 1998. This was due to the
following: (A) an increase in sales; offset by (B) the increase in start up
expenses relating to our continued international expansion; (C) expenses
related to some of our new compensation programs for our associates; (D) the
$750,000 buyout of a contract with Ray Robbins, who is an associate and
shareholder; and (E) expenses related to our secondary offering in August
1999. The secondary offering registered shares of our common stock, for sale
by certain existing shareholders. We expect our earnings trend to soften in
the first half of 2000 as we expect to incur significant start up costs
associated with launching our Japanese operations; scheduled for the summer of
2000. However like our competitors have seen and reported, we foresee the
Japanese market potential as exceptional.

  Our revenues are primarily from sales of our products and our associate
starter and renewal packs, which include some combination of our products and
promotional materials. The purchase of a starter or renewal pack allows the
associate to purchase products at wholesale prices. If the associate purchases
a pack with a wholesale price of $300 or higher, the associate also receives a
$50 credit toward admission to one of our corporate events. Our packs sold to
associates contain various combinations of our products and promotional
materials. We offer a comparable associate starter pack in each country in
which we do business; however, each country has different regulatory
guidelines which must be followed and therefore not all types of packs are
offered in all countries. All pack prices stated in this report are translated
into United States currency.

  Each of our starter packs sold, contain 0 to 30 different combinations of
our various nutritional and topical products sold and 10 to 250 different
combinations of our various promotional materials sold. On average, the total
wholesale value of the nutritional and topical products contained in each pack
is between 60% and 70% of the packs wholesale value. On average, the total
promotional materials value contained in each kit is between

                                      21


30% and 40% of the packs wholesale value. The average wholesale selling price
and total wholesale value of our starter packs sold to our associates are
follows:

  .  In the United States and Canada associates purchase starter packs as
     follows:

    (1)  Prior to June 1998, the starter packs could be purchased at
         $49.00, $229.00, $339.00, $568.00 and $1,000.00 levels. The
         average wholesale values of the contents of our starter packs was
         approximately $16.12, $44.62, $322.81, $817.32 and $1,138.83,
         respectively.

    (2)  Beginning in June 1998, starter packs could be purchased at
         $29.00, $49.00, $289.00, $664.00 and $1,000.00 levels. The average
         wholesale values of the contents of our starter packs were
         approximately $16.12, $44.62, $322.81, $817.32 and $1,138.83,
         respectively. Beginning in April 1999, the average wholesale
         values of the contents of our starter packs is approximately
         $15.05, $43.25, $319.50, $814.95 and $1,153.95.

  .  In Australia, only one associate starter pack is available, is priced at
     approximately $29.00, and has an approximate wholesale value of $19.06.

  .  In the United Kingdom, starter packs can be purchased at approximately
     $29.00, $49.00 and $289.00 with an average wholesale value of
     approximately $15.26, $103.17 and $380.00, respectively.

  Associates who do not renew their associate status may continue to purchase
our products at the wholesale price and resell the products; however, they
would not earn commissions under our compensation plan. Associates can renew
their status each year by either:

  (1)  renewing as a preferred customer and continue to sponsor new
       associates;

  (2)  purchase a renewal pack; or

  (3)  earn enough personal points volume from commissionable product sales
       to automatically renew their associate status for one year.

  The average selling price of the renewal packs sold to associates are as
follows:

  .  In the United States and Canada:

    (1)  Prior to June 1998, renewal packs could be purchased at $49.00,
         $229.00 or $568.00 levels.

    (2)  Beginning in June 1998, renewal packs can be purchased at $29.00,
         $200.00 or $350.00, levels.

  .  In Australia, renewal packs can be purchased at approximately $29.00,
     $200.00 and $350.00 levels.

  Associates are also eligible to purchase upgrade packs. Upgrade packs are
accounted for as renewal packs, as they renew an associate's membership for
one year from the time of upgrade. Upgrade packs are sold to associates as
follows:

  .  In the United States and Canada:

    (1)  Prior to June 1998, associates could purchase upgrade packs at
         approximately $229.00, $339.00, $568.00 and $1,000.00 levels.

    (2)  Beginning in June 1998, upgrade packs can be purchased at $289.00,
         $375.00, $664.00 and $1,000.00 levels.

  .  Beginning in April 1999, Australian associates can purchase upgrade
     packs at $49.00, $289.00, $375.00 and $664.00 levels.

  .  In the United Kingdom, upgrade packs can be purchased at $289.00,
     $375.00 and $664.00 levels.

  We generally recognize revenues when products or promotional materials are
shipped. Our revenues are based primarily on the wholesale prices of the
products sold. We defer revenue received from the sale of

                                      22


promotional packs to the extent that it is greater than the wholesale value of
the individual items included in such packs. Revenues from promotional packs
are allocated between products and events admission based on the proportionate
fair value of these items. Allocated event revenues are also deferred. All
deferred revenue is amortized over a 12-month period. Total deferred revenue
was approximately $809,000, $662,000 and $845,000 at December 31, 1997, 1998
and 1999, respectively.

  Associates are compensated by commissions, which are our most significant
expense. Commissions are paid to associates based on the following:

  .  their placement and position within our compensation plan;

  .  volume of direct commissionable sales; and

  .  number of new enrolled associates.

  In October 1998, we revised portions of our compensation plan to perfect our
global seamless downline compensation concept and ensure compliance with
common international standards for paying commissions. The commission pool, as
a whole, remains unchanged and we do not intend for commissions, under our
revised compensation plan, to materially exceed 42% of commissionable net
sales.

  Our United States federal statutory tax rate was 34% for 1997 and 35%
beginning in 1998. We pay taxes in Australia at a statutory tax rate of 36%
and in the United Kingdom at 31%. We expect to pay taxes in Japan at a
statutory tax rate of 54%. We also pay taxes in various state jurisdictions at
an approximate average statutory tax rate of 3%. As our international
expansion continues, a portion of our income will be subject to taxation in
the countries in which we operate. We may receive foreign tax credits that
would reduce the amount of United States taxes we owe, based upon the amount
of foreign taxes paid. We may not be able to use all of such foreign tax
credits in the United States. The use of the foreign tax credits is based upon
the proportionate amount of net sales in each country. Because many of the
countries that we may expand to during 2000 and beyond have maximum statutory
tax rates higher than the United States tax rate, we could pay a higher
overall effective tax rate on our consolidated operations.

Year ended December 31, 1999 compared with the year ended December 31, 1998

  Net Sales. Net sales increased 9.0% to $179.7 million in 1999 from $164.9
million in 1998. This increase was primarily composed of the following:

  .  A $7.8 million increase from the sale of several new products introduced
     during 1999 and from existing products that were not available for sale
     in other countries in 1998. Also contributing to the increase was the
     opening of our United Kingdom operation in November 1999 and the opening
     of our Australian operations in October 1998.

  .  A $4.5 million increase in existing product sales resulting from an
     increase in the volume of products sold and having operations in
     Australia open for the entire fiscal 1999.

  .  An increase of $2.6 million from associate pack sales. Of this $2.6
     million increase, approximately $1.5 million resulted from an increase
     in the number and a change in the mix of associate packs sold to new
     associates. The additional increase of $1.1 million resulted from an
     increase in associate renewal packs sold. The increase in the number of
     packs sold is a result of our international expansion and the hiring of
     a marketing firm to concentrate on our associate renewal program. We
     will continue to explore new strategies to further the increase in
     associate pack sales and renewal pack sales.

  Cost of Sales. Cost of sales increased 7.3% to $29.1 million in 1999 from
$27.1 million in 1998. As a percentage of net sales, cost of sales decreased
to 16.2% for 1999 from 16.5% in 1998. The decrease in cost of

                                      24


sales as a percentage of net sales was primarily due to changes in the product
mix and the volume of finished goods sold. The dollar amount increase was
primarily due to:

  .  a net increase related to the increased volume and the product mix of
     finished goods sold;

  .  the recording of $160,000 for recovery of inventory in 1998 which had
     been written off in December 1997; and

  .  a write-off of approximately $600,000 for other product changes.

  Commissions. Commissions consist of payments to associates for sales
activity and downline growth. Commissions increased 10.4% to $73.6 million in
1999 from $66.7 million in 1998. As a percentage of net sales, commissions
increased to 40.9% in 1999 from 40.4% in 1998. The increase was the direct
result of the following:

  .  an increase in the number of associate packs sold;

  .  the introduction of new incentive programs for associates, including the
     fast start program;

  .  the start up of operations in Australia in October 1998; and

  .  the start up of operations in the United Kingdom in November 1999.

  Gross Profit. Gross profit increased 8.3% to $77.0 million in 1999 from
$71.1 million in 1998. As a percentage of net sales, gross profit decreased to
42.9% in 1999 from 43.1% in 1998. These changes were primarily attributable to
the factors described above.

  Selling and Administrative Expenses. Selling and administrative expenses
consist of human resource expenses, including wages, bonuses and marketing
expenses, and are a mixture of both fixed and variable expenses. Selling and
administrative expenses increased 9.4% to $34.9 million in 1999 from $31.9
million in 1998. As a percentage of net sales, selling and administrative
expenses increased to 19.4% in 1999 from 19.3% in 1998. The dollar amount of
the increase was due primarily to sales increases, which increased freight
costs by $900,000, and a $2.3 million increase in wages and contract labor
expenses resulting from pay raises and an increase in personnel for the
Australian and United Kingdom operations.

  Other Operating Costs. Other operating costs include utilities,
depreciation, travel, office supplies and printing expenses. Other operating
costs increased 16.7% to $26.1 million in 1999 from $22.4 million in 1998. As
a percentage of net sales, other operating costs increased to 14.5% in 1999
from 13.6% in 1998. The dollar amount increase was primarily due to the
following:

  .  a $750,000 charge for the cancellation of the remaining incentive
     contract with Ray Robbins, as described in the notes to the Consolidated
     Financial Statements; in Item 14 of this report beginning on page F-1;

  .  $1.7 million for consulting services related to our international
     expansion;

  .  $350,000 for settlement of various lawsuits;

  .  $225,000 incurred related to our secondary offering for certain existing
     shareholders; and

  .  $200,000 for additional research and development costs related to our
     recently opened laboratory facility.

  Write-off of Deferred Offering Costs. During August 1998, we withdrew our
original underwritten institutional/retail offering and recorded a one-time
charge of approximately $847,000. In September 1998, we began the direct
initial public offering, which was not underwritten and was completed on
February 12, 1999.

  Interest Income. Interest income increased 677.7% to $713,000 in 1999 from
$92,000 in 1998. As a percentage of net sales, interest income increased to
0.4% in 1999 from 0.1% in 1998. The increase was primarily due to the receipt
of the initial public offering net proceeds, which we invested in interest
bearing accounts and certain investments.

                                      25


  Interest Expense. Interest expense increased 200.0% to $150,000 in 1999 from
$53,000 in 1998. As a percentage of net sales, interest expense increased to
0.1% in 1999 from 0.0% in 1998. The increase was due primarily to the signing
two lease agreements with a bank, to purchase various equipment for our
warehouse and laboratory facility.

  Other Expense, Net. Other expense consists of penalties related to tax
payments for payroll, income and sales and miscellaneous nonoperating items.
Other expense decreased (61.9%) to $114,000 in 1999 from $299,000 in 1998. As
a percentage of net sales, other expense decreased to 0.1% in 1999 from 0.3%
in 1998. For the year ended December 31, 1999, other expense consisted
primarily of certain federal tax penalties. For the year ended December 31,
1998, other expense consisted primarily of the write-off of abandoned fixed
assets of $250,000.

  Income Tax Expense. Income tax expense remained at $5.7 million for both
1999 and 1998; however, our effective tax rate decreased to 34.7% in 1999 from
36.4% in 1998. Our effective tax rate decreased primarily as a result of the
establishment of a Foreign Sales Corporation and an overall increase in
international sales, which are not subject to state income taxes averaging 3%.

  Net Income. Net income increased 7.3% to $10.8 million in 1999 from $10.1
million in 1998. As a percentage of net sales, net income decreased to 6.0% in
1999 from 6.1% in 1998. The dollar amount of the increase was due to net sales
increasing by 9% offset by expenses incurred related to our international
expansion and cancellation of the remaining incentive compensation contract
for $750,000.

Year ended December 31, 1998 compared with the year ended December 31, 1997

  Net Sales. Net sales increased 9.5% to $164.9 million in 1998 from $150.6
million in 1997. This increase was primarily composed of the following:

  .  A $10.8 million increase from the sale of several new products
     introduced during 1998 and from existing products that were not
     available for sale during the first nine months of 1997. Also
     contributing to the increase was the opening of our Australian operation
     in October 1998.

  .  An increase of $10.8 million in existing product sales. This increase
     resulted solely from increases in the volume of products sold.

  .  A decrease of ($7.3 million) due to an overall decrease in associate
     pack sales. A decrease of approximately ($8.6 million) in associate pack
     sales related to the enrollment of new associates, which was partially
     offset by a $1.3 million increase in renewal packs sold to associates.
     Associate pack sales decreased due to a delay in introducing the new
     associate packs until May 1998. In addition, we believe the slowdown was
     caused by associates focusing on the pre-opening activities in
     Australia, resulting in a temporary decrease in domestic recruiting and
     pack sales.

  Cost of Sales. Cost of sales increased 9.7% to $27.1 million in 1998 from
$24.7 million in 1997. As a percentage of net sales, cost of sales increased
to 16.5% for 1998 from 16.4% in 1997. The increase in cost of sales was due to
a $2.7 million increase in net sales of finished goods and a slight increase
in the price of raw materials due to using a new vendor. These increases were
partially offset by a ($200,000) decrease in freight due to a change in
vendors and a ($100,000) decrease in normal costs of spoilage and shrinkage of
inventory.

  Commissions. Commissions consist of payments to associates for sales
activity and downline growth. Commissions increased 8.1% to $66.7 million in
1998 from $61.7 million in 1997. As a percentage of net sales, commissions
decreased to 40.4% in 1998 from 41.0% in 1997. The slight decrease as a
percentage of net sales was the direct result of a decrease in the number of
associate packs sold and of our operations beginning in Australia.

  Gross Profit. Gross profit increased 10.9% to $71.1 million in 1998 from
$64.2 million in 1997. As a percentage of net sales, gross profit increased to
43.1% in 1998 from 42.6% in 1997. These changes resulted from the factors
described above.

                                      26


  Selling and Administrative Expenses. Selling and administrative expenses
consist of human resource expenses, including wages, bonuses and marketing
expenses, and are a mixture of both fixed and variable expenses. Selling and
administrative expenses increased 14.5% to $31.9 million in 1998 from $27.8
million in 1997. As a percentage of net sales, selling and administrative
expenses increased to 19.3% in 1998 from 18.5% in 1997. The dollar amount
increase was a result of increased labor costs due to sales volume increases,
$1.0 million spent on our first large-scale national associate meeting and
$400,000 related to the opening of our Australian operations.

  Other Operating Costs. Other operating costs include utilities,
depreciation, travel, office supplies and printing expenses. Other operating
costs increased 15.2% to $22.4 million in 1998 from $19.4 million in 1997. As
a percentage of net sales, other operating costs increased to 13.6% in 1998
from 12.9% in 1997. The dollar amount increase was primarily due to the
following:

  .  $1.5 million in additional expenses related to our expansion into
     Australia and research into the potential expansion into other
     international markets;

  .  $1.0 million increase in depreciation expense; and

  .  $500,000 increase in rent, repair and maintenance due to the addition of
     our new laboratory and the relocation of our Texas distribution center.

  Cancellation of Incentive Compensation Agreements. Cancellation of incentive
compensation agreements consists of a one-time charge in 1997 totaling
approximately $2.2 million. This charge resulted from the exchange of shares
of our common stock for the cancellation of certain incentive compensation
agreements.

  Write-off of Deferred Offering Costs. During August 1998, we withdrew our
original underwritten institutional/retail offering and expensed $847,000
related to the offering, which included printing, legal, accounting and
roadshow costs. In September 1998, we began the direct initial public
offering, which was not underwritten and was completed on February 12, 1999.

  Interest Income. Interest income increased 10.8% to $92,000 in 1998 from
$83,000 in 1997. As a percentage of net sales, interest income increased to
0.1% in 1998 from 0.0% in 1997. The slight increase was the result of
converting accounts receivable from a related party to interest bearing notes
receivable due from shareholders.

  Interest Expense. Interest expense increased 354.5% to $53,000 in 1998 from
$11,000 in 1997. As a percentage of net sales, interest expense remained at
0.0% in 1998 and in 1997, respectively. The dollar amount of the increase was
the result of paying interest on various capital leases.

  Other Expense, Net. Other expense consists of royalties from vendors and
miscellaneous nonoperating expenses. Other expense increased 931.0% to
$299,000 in 1998 from $29,000 in 1997. As a percentage of net sales, other
expense increased to 0.3% in 1998 from 0.0% in 1997. The 1998 increase in
expense was primarily due to the write-off of abandoned fixed assets of
$250,000.

  Income Tax Expense. Income tax expense increased 38.8% to $5.7 million in
1998 from $4.2 million in 1997. Our effective tax rate increased to 36.4% in
1998 from 28.0% in 1997. The increase in our effective tax rate was primarily
the result of reorganizing our corporate structure, effective as of June 1,
1997. Prior to that date, the income from partnerships related to Mannatech
was subject to income tax only at the individual partners' level.

  Net Income. Net income decreased (5.3%) to $10.1 million in 1998 from $10.6
million in 1997. As a percentage of net sales, net income decreased to 6.1% in
1998 from 7.0% in 1997. The decrease was due to the increase in net sales
offset by a one-time charge of approximately $847,000 for the canceled initial
public offering, costs incurred in connection with the international
expansion, income tax expense and the other factors described above.

Seasonality and Selected Quarterly Statements of Income

  We believe the impact of seasonality on our results of operations is
minimal. Historically, the first quarter has been slower each year and this
trend has continued in 2000. This trend may change as we continue to expand
internationally and international markets become a more significant part of
our business. We may experience variations on our quarterly results of
operations in response to, among other things:

  .  a concentration on opening new international markets;

  .  the timing of the introduction of new products;

  .  the recruiting and retention of associates;

  .  the general overall economic outlook;

  .  the general industry and network marketing industry conditions; and

  .  the consumer perception of our products and overall operations.

  As a result of these and other factors, our quarterly results could vary
significantly in the future. Period-to-period comparisons should not be relied
upon as an indication of future performance since we can give no assurances
that the revenue growth rate in new markets will follow our historical
pattern. The market price of our common stock could be adversely affected by
the above factors.

(1) In September 1998, we recorded a charge of approximately $941,000 for the
    write-off of various deferred offering costs. In December 1998, we
    recovered $94,000 of these costs.
(2) During the fourth quarter of 1998, we began operations in Australia and
    incurred approximately $1.0 million in start-up costs. In addition, we
    expensed $500,000 for ongoing modification costs associated with our
    internally developed software.
(3) For the second quarter of 1999, income before income taxes has been
    reduced by a $750,000 charge for the cancellation of an incentive
    contract, $400,000 for consulting services related to our international
    expansion, $200,000 for settlement of a lawsuit and $100,000 for
    additional research and development costs related to the opening of our
    laboratory facility.
(4) For the third quarter of 1999, income before income taxes has been reduced
    by $225,000 related to the secondary offering of registering shares of our
    common stock for sale by certain shareholders.
(5) For the fourth quarter of 1999, income before income taxes has been
    reduced by $1.0 million related to the start up expenses for operations in
    the United Kingdom and Japan.
(6) Computed on the basis described in Note 1 in the notes to the Consolidated
    Financial Statements.

  The following table sets forth certain unaudited quarterly results of
operations expressed as a percentage of net sales for each of the eight
quarters ending with the year ended December 31, 1999.

Liquidity and Capital Resources

  In February 1999, we received approximately $9.2 million in net proceeds
from the sale of our common stock in our initial public offering. In the
initial public offering, some of our existing shareholders sold 1,556,016

                                      29


shares and we sold 1,500,000 shares of our common stock, at $8.00 per share.
We planned to use approximately $6.3 million of our proceeds from the initial
public offering for international expansion, primarily for product
registration, initial inventory requirements and similar items and have
expended approximately $4.4 million on these items as of December 31, 1999.
The remaining $2.9 million was used to fund working capital and for general
corporate purposes. In February 1999, we also received $641,271 from the
exercise of 475,015 outstanding warrants at $1.35 per share. During 1999, we
also received $785,600 from the exercise of 563,774 stock options at a price
per share ranging from $1.35 to $2.00 per share.

  Our primary capital requirement is to fund working capital to support our
growth. In the past, we financed our operations mostly through cash flows from
operating activities and capital leases. As a result of our expenditures on
the facilities, equipment and personnel necessary to support our growth and
international expansion, we had a working capital deficiency of $12.4 million
as of December 31, 1998 compared to working capital of $11.7 million at
December 31, 1999. In 1998, we invested approximately $6.1 million, in the
relocation of our distribution center to Coppell, Texas, the completion of our
new laboratory facility and beginning operations in Australia. In 1999, we
invested approximately $600,000, in our expansion into the United Kingdom.
These projects were funded primarily through operating cash flow and capital
leases in 1998 and from operating cash flow in 1999.

  We paid approximately $9.9 million and $1.3 million in dividends to our
shareholders in 1998 and 1999, respectively. In 1998, current liabilities
increased due to an increase in payables, income taxes and inventory
purchases. The increase was primarily related to increased sales volume in
1998, the costs of the initial public offering, our expansion into Australia
and research into future planned expansion into other international markets.
In 1999, our current liabilities decreased due to our using the net proceeds
of the initial public offering to reduce accounts payable and accrued
expenses, an increase in net sales and a reduction in income taxes due to the
income tax benefit related to the exercise of warrants and stock options.

  In March and August 1998, we entered into two capital leases with principal
amounts of $631,000 and $841,000, respectively. These capital leases bear
interest at 9.3%, are collateralized by the leased assets and are payable in
thirty-six monthly installments. In July 1998, we entered into a thirty-six
month, unsecured note payable with a finance company to finance our three-year
product liability insurance premium. The initial principal amount of this note
was $435,670, the interest rate is 8.0% and monthly installments are due
through December 2000.

  Net cash provided by operating activities was $19.8 million, $18.1 million
and $4.8 million in 1997, 1998 and 1999, respectively. Throughout these years,
increases in net sales were partially offset by increases in inventory and
other expenses related to our international expansion and a decrease in income
tax payable of approximately $3.5 million from the tax benefit related to the
exercise of warrants and options. In 2000, we expect to spend up to an
estimated $2.0 million for start-up costs and between $1.0 and $2.0 million
for initial inventory for our planned expansion into Japan in the summer of
2000.

  Net cash (used in) investing activities was ($8.9 million), ($4.4 million)
and ($4.6 million) in 1997, 1998 and 1999, respectively. In 1997 these
activities consisted primarily of purchases of equipment and build-out of
leased facilities in connection with our relocation to our new headquarters
facility. In 1998, these activities consisted of the relocation of our Texas
distribution center, the build-out of our research and development facility
and the development and implementation of our proprietary software program. In
1999, these activities consisted primarily of purchases of computer hardware,
internal development of computer software and furnishings for our Australian
and United Kingdom headquarters and investing the net proceeds from the
initial public offering into investments offset by the repayment of the notes
receivable due from certain shareholders to us of approximately $974,000. We
believe the new facilities and software program should be sufficient for our
immediate needs. However, in 2000 we intend to spend up to an estimated $3.8
million for translation of our software into other languages, additional
purchases of equipment and build-out of leased facilities for our planned
international expansion into Japan in the summer of 2000.

                                      30


  Net cash provided by (used in) financing activities totaled ($11.9 million),
($12.9 million) and $10.6 million in 1997, 1998 and 1999, respectively. In
1997, we made distributions to the partners of the partnerships of $4.1
million. Following the reorganization, we paid dividends on a monthly basis to
our shareholders in the amount of $0.02-$0.06 per share and paid dividends
each month until the completion of the initial public offering on February 12,
1999. Our board of directors intends, from time-to-time, to reevaluate this
policy after considering relevant factors, including the level of our net
income and alternative uses of retained earnings. In February 1999, the gross
initial public offering proceeds of approximately $12.0 million were received
and during 1999, proceeds of $785,000 were received from the exercise of stock
options offset by the repayment of capital leases and note payable of
approximately $800,000.

  Our existing capital resources, including cash provided by operating
activities, bank borrowings together with the proceeds from the initial public
offering and suspension of dividend payments to shareholders, should be
adequate to fund our operations for at least the next 12 months. We have no
present commitments or agreements with respect to any acquisitions or
purchases of manufacturing facilities or new technologies. Changes could occur
that would consume available capital resources faster than anticipated. Our
capital requirements depend on numerous factors, including:

  .  the timing and pace of our entry into international markets;

  .  growth in the number of associates; and

  .  our research and development efforts.

  If our existing capital resources, together with the net proceeds of the
initial public offering, are insufficient to meet our capital requirements, we
will be required to raise additional funds. We cannot be sure that additional
funding, if necessary, will be available on favorable terms, if at all.

Year 2000

  Prior to January 1, 2000, there was a great deal of concern regarding the
ability of computers to adequately distinguish 21st century dates from 20th
century dates due to the two-digit date fields used by many computer systems
and software programs. This inability to distinguish whether "00" means 1900
or 2000, may have resulted in failures or the creation of erroneous results.
Most reports to date, however, are that computer systems are functioning
normally and the compliance and remediation work accomplished leading up to
2000 was effective and prevented such problems.

  We believe that our current versions of software products licensed from
third parties, are Year 2000 compliant. However, some of our suppliers may be
running earlier versions of software products that may not be Year 2000
compliant. We have evaluated the Year 2000 readiness of our vendors and third
parties and found no system failures. Furthermore, we currently are unaware of
any material operational issues or costs associated with preparing and
maintaining our computer and technology systems for the Year 2000. However, we
still may experience material unanticipated problems and costs caused by
undetected errors or defects, which could seriously harm our business.

  Our total cost associated with Year 2000 identification, remediation and
testing was approximately $100,000 and was funded through operating cash
flows. None of our applications failed to perform on January 1, 2000; however,
computer experts have warned that there may still be residual consequences of
the change in centuries. If we experience any application failures in 2000, it
could result in a decrease in sales of our products or an increase in the
allocation of resources to address the problem with the Year 2000. If this
should occur, we would have to resort to temporary manual processing, which is
not expected to have a material adverse impact on our short-term operations.

Impact of Inflation

  We believe that inflation historically has not had a material impact on our
operations or profitability. In 1998, we expanded into Australia and in 1999,
into the United Kingdom. We plan to expand into Japan in the

                                      31


summer of 2000. Revenues and expenses in foreign markets are currently
translated using historical and weighted-average currency exchange rates;
therefore a weakening United States dollar should have a positive impact
whereas a strengthening United States dollar should have a negative impact on
translations of our foreign operations. The planned expansion into Japan may
not proceed as planned if there is a further economic downturn or fluctuation
in Asian currencies. We intend to proceed cautiously with the Japanese
expansion in order to help minimize any material impact on our operations or
profitability.

Subsequent Event

  On February 29, 2000, a class action lawsuit was filed of record in District
Court, County of Boulder, Colorado; naming Mannatech and three other companies
as co-defendants. The other defendants were involved in certain health benefit
programs offered to our Associates. The suit alleged the defendants were
marketing and selling illegal health insurance policies, committed fraud and
failure to pay benefits under such policies, which caused economic loss to the
plaintiffs and others. The suit seeks a trial by jury and an unspecified
amount of damages. Mannatech believes it has valid defense and that the
allegations are completely without merit. We intend to vigorously defend our
position. Nevertheless, an adverse resolution to this matter could have a
material adverse effect on our business, results of operations, financial
condition and liquidity.

Recent Financial Accounting Standards Board Statements

  In June 1998, the Financial Accounting Standards Board issued Financial
Accounting Standard No. 133, "Accounting for Derivative, Instruments and
Hedging Activities." This statement establishes accounting and reporting
standards for derivative financial instruments, including certain derivative
financial instruments imbedded in other contracts and for hedging activities.
In June 1999, the Financial Accounting Standards Board issued Financial
Accounting Standard No. 137, which defers the effective date of Financial
Accounting Standard No. 133 to fiscal years beginning after June 15, 2000. As
we do not have any derivative financial instruments, this pronouncement is not
expected to impact us.

Forward-Looking Statements

  Some of our statements under "Business," "Properties," "Legal Proceedings,"
"Management's Discussion and Analysis of Financial Condition and Results of
Operations," "Quantitative and Qualitative Disclosures about Market Risk" and
the Notes to Consolidated Financial Statements and elsewhere in this report
constitute "forward-looking statements" within the meaning of Section 21E of
the Securities Exchange Act of 1934 that are subject to certain events, risk
and uncertainties that may be outside our control. These forward-looking
statements include statements of:

  .  management's plans and objectives for our future operations and future
     economic performance;

  .  our capital budget and future capital requirements;

  .  meeting our future capital needs;

  .  realization of our deferred tax assets;

  .  the level of future expenditures; and

  .  the outcome of regulatory and litigation matters, and the assumptions
     described in this report underlying such forward-looking statements.

  Actual results and developments could differ materially from those expressed
in or implied by such statements due to a number of factors, including,
without limitation:

  .  those described in the context of such forward-looking statements;

  .  future product development and manufacturing costs;

                                      32


  .  timely development and acceptance of new products;

  .  the entrance into new countries and markets;

  .  the impact of competitive products and pricing;

  .  the political and economic climate in which we conduct operations; and

  .  the risk factors described from time to time in other documents and
     reports filed with the Securities and Exchange Commission.

  In some cases, forward-looking statements are identified by terminology such
as "may," "will," "should," "could," "expects," "plans," "intends,"
"anticipates," "believes," "estimates," "approximates," "predicts,"
"potential" or "continue" or the negative of such terms and other comparable
terminology.

  Although we believe that the expectations reflected in the forward-looking
statements are reasonable, we cannot guarantee future results, levels of
activity, performance or achievements. Moreover, neither we nor anyone else
assumes responsibility for the accuracy and completeness of such statements.
We are under no duty to update any of the forward-looking statements after the
date of this report.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

  We do not engage in trading market risk sensitive instruments and do not
purchase as investments, as hedges, or for purposes "other than trading,"
instruments that are likely to expose us to certain types of market risk,
including interest rate, commodity price or equity price risk. We do have
investments but there has been no material change in our exposure to interest
rate risk on our investments. We have not issued any debt instruments, entered
into any forward or futures contracts, purchased any options or entered into
any swaps.

  We also are exposed to certain other market risks, including changes in
currency exchange rates as measured against the United States dollar. The
value of the United States dollar affects our financial results. Changes in
exchange rates may positively or negatively affect our sales (as expressed in
United States dollars), gross margins, operating expenses and retained
earnings. When the United States dollar increases against currencies in which
we sell products or a weakening exchange rate against currencies in which we
incur costs, our net sales or costs may be adversely affected. We have
established policies, procedures, and internal processes governing the
management of market risk and the use of any financial instruments to manage
our exposure to such risks. The sensitivity of earnings and cash flows to
variability in currency exchange rate is assessed by applying an appropriate
range of potential rate fluctuations to our assets, obligations and projected
transactions denominated in foreign currency. Based upon our overall currency
rate exposure at December 31, 1999, we do not believe that its exposure to
exchange rate fluctuations will have a material impact on our consolidated
financial position or consolidated results of operations. All statements other
than historical information incorporated in this Item 7A are forward-looking
statements. The actual impact of future market changes could differ materially
due to, among other things, factors discussed in this report.

   Class II.................................    2001    Fioretti, Sullivan
   Class III................................    2002    Barker, Persinger, Doyle


Committees of the Board of Directors

  Our board of directors has three committees each composed solely of two of
our independent directors, Messrs. Barker and Sullivan. The committees and
their function are as follows:

  .  The audit committee is charged with reviewing our annual audit and
     meeting with our independent accountants to review our internal controls
     and financial management practices;

  .  The compensation committee is responsible for establishing salaries,
     bonuses and other compensation for our executive officers.

  .  The option committee has the authority to determine the terms and
     conditions of each option to be issued under our stock option plans and
     the responsibility for administration of each such plan.

  In addition, the Company also maintains an executive operating committee
comprised of seven executive officers. The executive operating committee has
the authority to make specific recommendations and render advice to the board
of directors on various matters regarding operations. The eight members
include the President, Chief Executive Officer and all of our Executive and
Senior Vice Presidents.

Director Compensation

  Messrs. Barker and Sullivan, two of our three independent directors, each
receives an annual fee of $30,000 for serving on our board of directors. In
addition, our directors are reimbursed for their reasonable out-of-pocket
expenses, in connection with their travel to and attendance at meetings of our
board of directors or its committees. On October 19, 1999, we granted 50,000
stock options to Mr. Barker at an exercise price of $7.69 per share, which was
the approximate fair value of our common stock on that date.

Section 16(a) Beneficial Ownership Reporting Compliance

  Section 16(a) of the Exchange Act requires our directors and executive
officers, and persons who own more than 10% of our common stock, to file with
the Commission initial reports of ownership and reports of changes in
ownership of our common stock and other equity securities. Such persons are
required by the Commission's regulations to furnish us with copies of all
Section 16(a) reports they file. Prior to our initial public offering, our
directors, executive officers and persons who own more than 10% of our common
stock were not subject to the requirements of the Exchange Act.

  Based solely upon a review of the copies of such reports or written
representations that no other reports were required, we believe that during
the fiscal year ended December 31, 1999 our executive officers, directors and
greater than 10% beneficial owners complied with all applicable Section 16(a)
filing requirements, except for the following:

                                      37


  .  Stephen D. Fenstermacher, Donald W. Herndon, Gwendolyn J. Pennington,
     Terry L. Persinger, Eileen M. Vennum and Brad G. Wayment, all of whom
     are our executive officers did not timely file their initial report on
     Form 3.

  .  Steven A. Barker, Ph.D., one of our directors and Jeffrey P. Bourgoyne,
     Stephen D. Fenstermacher and Eileen M. Vennum, all of whom are our
     executive officers did not timely file Form 4's required as a result of
     being granted stock options.

  .  Mr. William C. Fioretti, 10% beneficial owner of our common stock, did
     not timely file Form 4's on seven different occasions relating to the
     sale of his shares.

  .  Peter E. Hammer, one of our executive officers, did not timely file a
     Form 4 on two occasions relating to sale of his shares.

  .  Donald W. Herndon, executive officer, did not timely report on a Form 4
     on two occasions relating to the sale of his shares.

  We have begun to send monthly reporting reminders to each of our executive
officers and 10% beneficial owners to assist in their Section 16(a) reporting
requirements.

Executive Employment Agreements

  We have employment agreements with each of Charles E. Fioretti, Patrick D.
Cobb, Anthony E. Canale, Bill H. McAnalley and Deanne Varner. These agreements
expire in September 2003 but will extend automatically for one additional year
unless both parties agree to terminate the contract before the end of any
term. In addition, in November 1999, we entered into an employment agreement
with Terry L. Persinger, which expires in November 2002. All of these
agreements provide for a current base salary, bonus compensation based upon
the management bonus plan formula the right to receive stock options and
certain confidentiality and non-compete clauses. If we terminate any of these
employment agreements for any reason other than reasons specified in the
agreements, the officer is entitled to receive an amount equal to the sum of
all salary and bonus that would have been paid during the remainder of their
employment agreement.

Management Bonus Plan

  Executive officers and some other members of corporate management are
eligible to receive bonuses in addition to their base salaries. Our
compensation committee is responsible for reviewing and approving bonuses for
these officers.

Compensation Committee Interlocks and Insider Participation

  In February 1999, after the completion of our initial public offering, our
board of directors established the compensation committee. The compensation
committee is responsible for decisions regarding compensation of our executive
officers. The compensation committee is composed solely of two of our three
independent directors, Messrs. Barker and Sullivan. None of the members of the
compensation committee has ever been an officer or employee of Mannatech.

Executive Compensation Report of the Board of Directors

  The compensation committee was formed in February 1999. Prior to February
1999, our board of directors performed the functions of the compensation
committee.

  This Executive Compensation Report discusses our executive compensation
policies and the basis for the compensation paid to our executive officers,
including the Chief Executive Officer, Charles E. Fioretti, during the fiscal
year ended December 31, 1999.

                                      40


  Compensation Policy. Our policy with respect to executive compensation has
been designed to:

  .  Adequately and fairly compensate executive officers in relation to their
     responsibilities, capabilities and contributions to Mannatech and in a
     manner that is commensurate with compensation paid by companies of
     comparable size or within our industry; and

  .  Reward our executive officers for the achievement of short-term
     operating goals and for the enhancement of our long-term value.

  Components of compensation. The primary components of compensation paid to
our executive officers and the relationship of such components of compensation
to our performance are discussed below:

  (a) Base Salary. As the compensation committee was not formed until
      February 1999, the fiscal year ended December 31, 1999 base salaries
      were reviewed and approved by our board of directors. At the beginning
      of each new fiscal year the compensation committee reviews the base
      salaries of the executive officers to ensure the salaries are based
      correctly upon a number of factors. These factors include our
      performance (to the extent such performance can fairly be attributed or
      related to each executive officer's performance), as well as the nature
      of each executive officer's responsibilities, capabilities, loyalties
      and contributions. The compensation committee believes that base
      salaries for our executive officers have been reasonable in relation to
      our size and performance in comparison with the compensation paid by
      similarly sized companies or companies within the same industry.

  (b) Bonus. Our executive officers are eligible to participate in our
      Management Bonus Plan. The bonus plan is based upon the attainment of
      certain financial goals including general performance of Mannatech and
      to a reasonable degree, our performance in accordance with a projected
      budget. The bonuses for the fiscal year ended December 31, 1999 were
      reviewed and approved by the compensation committee and paid by January
      15, 2000. Subsequent bonuses paid to the executive officers will be
      reviewed and approved by the compensation committee and paid no less
      than annually. During the fiscal year ended December 31, 1999, our
      Chief Executive Officer, Charles E. Fioretti, was awarded an additional
      bonus of $56,536 for his efforts with respect to the completion of our
      initial public offering.

  (c) Other Annual Compensation. We maintain certain other plans and
      arrangements for the benefit of our executive officers and other
      management, including participation in the 401(k) plan, use of a
      company vehicle and health, life, automobile and long term disability
      insurance. During the last quarter of 1999, the compensation committee
      approved a new policy where by all employees at the Vice President
      level and above were awarded monthly car allowances of $500.00. In
      addition, the Chief Executive Officer, Chief Operating Officer's, Chief
      Financial Officer, Chief Scientific Officer, President, General Counsel
      and Chief Executive Officer of our subsidiaries were awarded the use of
      a vehicle leased by Mannatech. In 1999, the Chief Executive Officer
      elected not to use a vehicle leased by Mannatech. We believe these
      benefits are reasonable in relation to the executive compensation
      practices of other similarly sized companies or companies within the
      same industry.

  (d) Long-term Compensation. We maintain stock option plans to reward
      certain members of management for the attainment of certain goals or
      events. The stock option grants are reviewed and approved by our
      compensation committee. We believe these long-term compensation
      arrangements are reasonable in relation to the executive compensation
      practices of other similarly sized companies or companies within the
      same industry.

1999 Chief Executive Officer Compensation

  As previously described, the compensation committee considered several
factors in determining the Chief Executive Officer's compensation package,
with the primary factor being our performance and the competitive compensation
paid to other executive officers of comparable size companies of companies
within the same industry. Specific actions taken by the compensation committee
regarding Mr. Fioretti's 1999 compensation are summarized below:

  (a) Base Salary. As with our other executive officers, Mr. Fioretti's 1999
      salary was based on a number of factors. These factors include our
      performance, overall consolidated financial results, as well as the

                                      41


     nature of his responsibilities, capabilities, loyalties and
     contributions to Mannatech. For fiscal year 1999, Mr. Fioretti's salary
     remained at $600,000.

  (b) Bonus. Our Chief Executive Officer is allowed to participate in our
      Management Bonus Plan. Our bonus plan is based upon the attainment of
      certain financial goals. The board of directors approved a $56,536
      bonus to Mr. Fioretti in February 1999, prior to the formation of the
      compensation committee. The bonus was awarded in recognition of Mr.
      Fioretti's efforts relating to the successful completion of our initial
      public offering. In addition, Mr. Fioretti was paid $101,981 pursuant
      to the Management Bonus Plan.

  (c) Other Annual Compensation. All of our other executive officers may
      participate in our 401(k) plan, but the Chief Executive officer has
      elected not to participate at this time. In 1999, the compensation
      committee elected to bonus two remaining company-owned vehicles having
      a combined value of $112,595 to the Chief Executive Officer in lieu of
      a cash bonus. Mr. Fioretti has elected not to be furnished a vehicle
      leased by Mannatech at this time. Mr. Fioretti is also provided with
      health, life, automobile and long-term disability insurance coverage.

  $1 Million Pay Deductibility Cap. Under Section 162(m) of the Internal
Revenue Code, public companies are precluded from receiving a tax deduction on
compensation paid to executive officers in excess of $1 million, unless the
compensation is excluded from the $1 million limit as a result of being
classified as performance-based. At this time, none of our executive officers'
cash compensation levels exceed the $1 million pay limit. We do not anticipate
exceeding this limit in the near future. Nonetheless, the compensation
committee intends to periodically review its executive pay plans in light of
this regulation.

  Conclusion. The compensation committee believes the concepts discussed above
further the stockholders' interests and that officer compensation encourages
responsible management of Mannatech. The compensation committee regularly
considers the effect of executive compensation on shareholder interests. These
factors, reports of the executive operating committee and discussions with and
information compiled by various independent consultants retained by us will be
used in determining executive officer compensation.

(1) The compensation committee was formed on February 10, 1999; prior to that
    time, the board of directors approved compensation. The board of directors
    consisted of Messr. Charles E. Fioretti, Samuel L. Caster, Patrick D.
    Cobb, Chris T. Sullivan and Steven A. Barker Ph.D.

Stock Option Plans

  The 1997 Stock Option Plan was adopted by our board of directors and
approved by our shareholders on May 14, 1997. The 1998 Incentive Stock Option
Plan was adopted by our board of directors on April 8, 1998 and amended on
September 4, 1998 to increase the number of shares reserved for issuance from
500,000 to 1,000,000 shares. Both stock option plans are intended to encourage
investment by our officers, employees, non-employee directors and consultants
in shares of our common stock so that they will have an increased interest in
and greater concern for the welfare of Mannatech.

  Options granted under either stock option plan may either be incentive stock
options or options that do not qualify for treatment as incentive stock
options under Section 422 of the Internal Revenue Code of 1986. Options
granted under the 1998 Incentive Stock Option Plan may only be granted to our
officers, directors and employees.

  Incentive stock options may be granted under our stock option plans to any
person who is one of our officers or other employees (including officers and
employees who are also directors) or any parent or subsidiaries that

                                      42


may exist in the future. The exercise price of incentive stock options must be
at least the fair market value of a share of our common stock on the date of
grant.

  The following table sets forth information regarding our stock option plans
as of March 24, 2000:

 Option Plan............  1,000,000     963,500       $7.89         291,333    36,500


  The option committee has full and final authority in its discretion, subject
to the stock option plans' provisions, to determine, among other things:

  .  the individuals to whom options shall be granted;

  .  whether the option granted shall be an incentive stock option or a non-
     qualified stock option;

  .  the number of shares of our common stock covered by each option;

  .  the time or times at which options will be granted;

  .  the option vesting schedule;

  .  the exercise price of the options;

  .  the duration of the options granted;

  .  to prescribe, amend and rescind rules and regulations relating to the
     stock option plans;

  .  accelerate or defer (with the consent of the optionee) the exercise date
     of any option; and

  .  authorize any person to execute on our behalf any instrument required to
     effectuate the grant of an option previously granted by our board of
     directors.

  The option committee consisting of two of our three independent directors,
Messr Barker and Sullivan, also has the power to decide upon and make rules
that control the stock option plans and take all other actions necessary for
the proper administration of the stock option plans. The stock option plans
may be changed or canceled by our board of directors at any time without the
approval of our shareholders, with a few exceptions. However, they may not
take action that affects options previously granted under the stock option
plans.

401(k) Plan

  On May 9, 1997, we adopted a 401(k) Pre-tax Savings Plan. All employees who
have been employed by us for at least 90 days at the beginning of a quarter
and are at least 21 years of age are eligible to participate. Employees may
contribute a maximum of 15.0% of their current compensation to the 401(k)
Plan, up to a statutorily prescribed annual limit. We will make regular
matching contributions to the 401(k) Plan in the amount of $0.25 for each
$1.00 contributed by a participating employee, up to 6.0% of a participating
employee's annual compensation, including overtime. The 401(k) Plan also
provides that Mannatech can make profit-sharing contributions to the plan each
year based upon our profit. Employee contributions and our matching
contributions are paid to a corporate trustee and invested as directed by the
participating employee. Our contribution in the 401(k) Plan vests over 5 years
or earlier if the participating employee retires at age 65, becomes disabled
or dies. Payments to participating employees may also be made in the case of a
financial hardship. Payments may be made in a lump sum. The 401(k) Plan is
intended to qualify under Section 401 of the Internal Revenue Code of 1986, so
that contributions made by employees or by us to the 401(k) Plan, and income
earned on these contributions, are not taxable to employees until withdrawn
from the 401(k) Plan.

Item 13. Certain Relationships and Related Transactions

Loans to Officers

  We orally agreed to advance certain officers money to pay the taxes caused
by the cancellation of their incentive compensation agreements. On December
31, 1997, we made loans of $162,052 to Dr. Bill H. McAnalley Ph.D., our senior
vice president of research and product development, and of $121,782 to Peter
E. Hammer, our vice president of new business and international development.
The non-interest bearing loans were collateralized by shares of our common
stock owned by these officers. The loans were repaid in February 1999 after
the officers received the proceeds from the sale of their shares of common
stock in our initial public offering.

Loans to Agritech Labs, Inc.

  During 1996 and 1997, we made cash advances to Agritech Labs, Inc. and
Agritech Technology, Ltd. totaling approximately $918,000. The Agritech
companies were owned by individual partners of which over 90% of the Agritech
companies were owned by Messrs. Charles E. Fioretti, Samuel L. Caster, Patrick
D. Cobb, who are shareholders and executive officers of Mannatech and Mr.
William C. Fioretti, who is a shareholder and former executive officer of
Mannatech. Because we were concerned about the ability of these Agritech
companies to repay the loans, each of Messrs. William C. Fioretti, Charles E.
Fioretti, Samuel L. Caster and Patrick D. Cobb agreed to pay the obligations
that these Agritech companies owed Mannatech. Each of these individuals gave
promissory notes to us totaling approximately $918,000. Each promissory note
bore interest at 6.0% per year and was payable on the earlier of the sale of
the Agritech companies or December 31, 1998. The principal amount outstanding
under the notes issued by each of Messrs. William C. Fioretti, Charles E.
Fioretti and Samuel L. Caster at December 31, 1998 was approximately $275,400
and the principal amount outstanding under the note made by Mr. Patrick D.
Cobb at December 31, 1998 was approximately $45,900. On December 31, 1998, we
renewed the notes with an extended due date of December 31, 1999. On February
17, 1999, we signed new notes with each of the shareholders. The new notes
bear interest at 6.0% per year, with the first payment due immediately and the
remainder to be paid in annual installments through February 17, 2004. As of
December 31, 1999, the principal amount outstanding under the new notes made
by each of Messrs. William C. Fioretti, Charles E. Fioretti and Samuel L.
Caster is approximately $210,000 and the principal amount outstanding under
the new note made by Mr. Patrick D. Cobb is approximately $35,000. Mr. William
C. Fioretti has not paid his annual payment due February 17, 2000 of
approximately $45,000 related to such notes receivable; however we expect
payment in full and intend to pursue the collection of such note.

Commission Agreement, Consulting Fees and Receivables from Related Parties

  In 1998 and 1999, William C. Fioretti earned approximately $121,000 and
$453,000, respectively, for commissions pursuant to an agreement with
Mannatech, which commissions were paid in 1998 and 1999. On October 20, 1998,
we paid Mr. Fioretti $250,000 for consulting services he performed for us over
the course of 1998 in sports marketing and product development issues. Mr.
Fioretti is one of our founders, a major shareholder and the cousin of Charles
E. Fioretti, our chairman of the board and chief executive officer.

  During 1997, we advanced $125,000 to Mr. William C. Fioretti's brother-in-
law, which remained unpaid at December 31, 1998. During 1999, Mr. Fioretti
guaranteed the repayment of this payable to us; however, in December 1999, we
wrote off this loan, when we determined it was not collectible and released
Mr. Fioretti from his guarantee.

  (b) Reports on Form 8-K.

  On November 3, 1999, Mannatech filed a report on Form 8-K with the
Commission disclosing under Item 5--"Other Events" that on October 20, 1999,
shareholders controlling 74.5% of the voting stock of Mannatech acting by
written consent, amended our Bylaws in order to:

  .  allow our shareholders to set the size of the board; however, the board
     of directors must have a minimum of three directors;

  .  revise the procedures for call, notice and administration of board
     meetings;

  .  revise the duties of the Chairman of the Board to include presiding over
     and determining the order of business at board meetings;

  .  revise the procedures for amending certain Bylaws provisions adopted by
     our shareholders;

                                      49


  .  allow special meetings of the board to be called by the President or by
     two other directors acting together; however, 24-hour notice must be
     given for these meetings, which notice may, under some circumstances be
     waived; and

  .  provide that only board members may attend board meetings and that
     directors are not allowed to have personal legal counsel present, unless
     allowed by a majority vote of the directors.

  In the written consent, the shareholders also approved the expansion of the
board from five to seven members and elected Mr. James M. Doyle, Jr., as a
Class III director with his term expiring in 2002. This information was filed
November 3, 1999, on a preliminary information statement on Form Pre 14C (File

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Shareholders of
Mannatech, Incorporated

  In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of income, of changes in shareholders' equity and of
cash flows present fairly, in all material respects, the financial position of
Mannatech, Incorporated and its subsidiaries at December 31, 1998 and 1999,
and the results of their operations and their cash flows for each of the three
years in the period ended December 31, 1999, in conformity with accounting
principles generally accepted in the United States. These financial statements
are the responsibility of the Company's management; our responsibility is to
express an opinion on these financial statements based on our audits. We
conducted our audits of these statements in accordance with auditing standards
generally accepted in the United States, which require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on
a test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for the
opinion expressed above.

  Mannatech, Incorporated (the "Company") was incorporated in the State of
Texas on November 4, 1993, as Emprise International, Inc. Effective October
25, 1995, the Company changed its name to Mannatech, Incorporated. The
Company, located in Coppell, Texas, develops and sells proprietary nutritional
supplements and topical products through a network marketing system. The
Company currently sells its products in the United States, Canada, Australia
and the United Kingdom. Independent associates ("Associates") purchase
products, at wholesale, for the primary purpose of selling to retail consumers
or for personal consumption. In addition, Associates earn commissions on their
downline growth and sales volume.

  On April 22, 1998, the Company formed a wholly-owned subsidiary, Mannatech
Australia Pty Limited for the purpose of conducting business in Australia. The
Australian subsidiary, located in St. Leonards, began operations on October 1,
1998.

  On December 1, 1998, the Company formed a wholly-owned subsidiary, Mannatech
Limited, for the purpose of conducting business in the Republic of Ireland.
This subsidiary is dormant pending the start-up operations in the Republic of
Ireland.

  In April 1999, the company formed a wholly-owned subsidiary, Mannatech Ltd.,
for the purpose of conducting business in the United Kingdom as a limited
service provider. The United Kingdom subsidiary is located in Basingstoke,
Hampshire and began operations on November 15, 1999.

  On May 1, 1999, the Company formed a wholly-owned subsidiary, Mannatech
Foreign Sales Corporation, under the laws of Barbados to act as a "foreign
sales corporation" as defined in the United States Internal Revenue Code.

  On May 7, 1999, the Company formed a wholly-owned subsidiary, Internet
Health Group, Inc., a Texas corporation, for marketing its proprietary
products, specially developed nutritional supplements and sports nutrition
products over the Internet. Internet Health Group, Inc. is located in Dallas,
Texas, and operates through its website, www.clickwell.com, which began
operations on December 20, 1999.

Principles of Consolidation

  The consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiaries. All significant intercompany balances and
transactions have been eliminated in consolidation.

Reorganization

  In December 1994, to achieve certain tax efficiencies and to protect certain
of the Company's proprietary rights, the Company transferred certain of its
rights and interests in intellectual property, the right to use a supplier's
trademark and it's marketing rights to two affiliated partnerships ("Royalty
Partnership" and "Marketing Partnership," respectively, or collectively the
"Partnerships"). The Marketing Partnership was owned by two affiliated
partnerships that also shared common ownership with the Company. The
respective ownership interests in the Partnerships were structured with the
intention of retaining the same economic interests among the partners as that
of the shareholders of the Company. In the case of the intellectual property
and trademark transferred to the Royalty Partnership, the Company entered into
a 17-year agreement with the Royalty Partnership to pay a royalty based on
sales volume. In the case of the Marketing Partnership, the Company paid a
commission based on a specified percentage of sales volume. At the time of
transfer, the rights and interest in intellectual property, supplier's
trademark and marketing rights had a minimal basis. During 1994, the Company
also entered into separate incentive compensation agreements with two of its
shareholders pursuant to which the

                                      F-7


                            MANNATECH, INCORPORATED

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

Company agreed to pay commissions based on specified monthly sales volumes and
increases in number of new enrolled Associates. These agreements were designed
to compensate for the differences in ownership in the Partnerships for one of
the principal shareholders and to provide compensation to a shareholder in
lieu of receiving a Partnership interest.

  On June 1, 1997, in order to simplify the Company's ownership structure and
consolidate all operating activities, the Company entered into agreements to
effect a reorganization through merging with the corporate general partners of
the Partnerships (with the Company as the surviving corporation) and
exchanging 10,000,000 shares of the Company's common stock, par value $0.0001
per share, for the entire ownership interests of the corporate general
partners and the Partnerships and issued 2,027,571 shares of its common stock
in consideration for the cancellation of certain incentive compensation
agreements with a shareholder who is an associate, a shareholder who is an
executive officer and four other employees of the Company. The net effect of
the foregoing transactions was to increase the Company's common shares
outstanding by 12,027,571 while retaining substantially the same relative
original ownership of the Company. The only ownership percentage change among
the original shareholders related to 208,024 shares granted to one shareholder
in recognition of significant contributions to the Company, which resulted in
minor dilution to the other original seven shareholders at the time of the
exchange. The fair value of these additional shares was expensed, and included
in the cancellation of incentive compensation agreements in the statement of
income. No monetary consideration changed hands and the changes were designed
to reestablish the original economic characteristics of the Company. Aside
from the new shares issued to the four employees to cancel their incentive
compensation agreements, relative ownership interests, as evidenced by
retention of economic risks and benefits, remained virtually the same. After
the exchange, the Company terminated and liquidated the Partnerships at no
gain or loss. The merger was accounted using the historical basis for each
entity, effectively combining the entities as a pooling of interests.

Use of Estimates

  In preparing consolidated financial statements in conformity with generally
accepted accounting principles, management is required to make certain
estimates and assumptions that may affect the reported amounts of assets,
liabilities, revenues and expenses during the reporting periods. Actual
results may differ from such estimates.

Cash and Cash Equivalents

  The Company considers all highly liquid investments with original maturities
of three months or less to be cash equivalents.

Accounts Receivable Allowance Account

  Accounts receivable consist of a refund due for the overpayment of a 1998
sales tax assessment, a refund of value added tax from the United Kingdom and
payments due from vendors for the purchase of raw material inventories offset
by an allowance account for any amounts that are deemed uncollectible. The
balance of the allowance for doubtful accounts was approximately $58,000 at
both December 31, 1998 and 1999.

Inventories

  Inventories consist of raw materials and finished goods and are stated at
the lower of cost (using the first-in, first-out method) or market.


                                      F-8


                            MANNATECH, INCORPORATED

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

Property and Equipment

  Property and equipment are stated at cost, less accumulated depreciation
that is computed using the straight-line method over the estimated useful life
of each asset. Expenditures for maintenance and repairs are charged to expense
as incurred. The cost of property and equipment sold or otherwise retired and
the related accumulated depreciation are removed from the accounts and any
resulting gain or loss is included in other (income) expense.

  Property and equipment are reviewed for impairment whenever an event or
change in circumstances indicates the carrying amount of an asset or group of
assets may not be recoverable. The impairment review includes a comparison of
future cash flows expected to be generated by the asset or group of assets
with their associated carrying value. If the carrying value of the asset or
group of assets exceeds expected cash flows (undiscounted and without interest
charges), an impairment loss is recognized to the extent the carrying amount
of the asset exceeds its fair value.

Other Assets

  Other assets consist primarily of deposits in an Australian bank that
include a restricted term deposit of approximately $88,000 at December 31,
1998 and $99,000 at December 31, 1999. This term deposit matures every six
months and is automatically renewed by the Company as security for the
Australian building lease.

Deferred Offering Costs

  Deferred offering costs were costs incurred in connection with the initial
public offering of the Company's common stock (the "Offering"). The Offering
was consummated on February 12, 1999 and the deferred offering costs were
deducted from the proceeds received.

Accounts Payable

  The Company records book overdrafts in its cash accounts as accounts
payable. Accounts payable includes book overdrafts of $1,309,908 at December
31, 1998.

Income Taxes

  The Company accounts for income taxes using the asset and liability approach
to financial accounting and reporting for income taxes. In the event that
differences between the financial reporting bases and the tax bases of the
Company's assets and liabilities result in net deferred tax assets, the
Company evaluates the probability of realizing the future benefits indicated
by such assets. A valuation allowance is provided for a portion or all of the
net deferred tax assets when it is more likely than not that such portion, or
all of such deferred tax assets, will not be realized.

  Prior to the merger of the Partnerships, the Company and the Partnerships
filed separate tax returns. Prior to June 1, 1997, no provision for income
taxes was necessary in the consolidated financial statements for the income
attributable to the Partnerships because, as partnerships, they were not
subject to federal income tax because the tax effect of their activities
flowed through directly to the individual partners. Beginning June 1, 1997,
all income earned by the Company became subject to income tax.

Pro Forma Information (Unaudited)

  Pro forma income tax information has been provided, using the statutory tax
rate of the Company, as if all of the Company's and the Partnerships' income
had been subject to income taxes.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


Revenue Recognition

  Revenue is recognized for product sales upon the receipt of payment and
shipment of the products to the Associates. A reserve for product returns is
accrued based on historical experience. Revenues are received for starter and
renewal packs sold to Associates, which include nutritional products, sales
aids and admission to a corporate event.

  The Company defers revenue received from the sale of the starter and renewal
packs, which is in excess of the average wholesale value of the individual
items included in such packs. Such deferrals are amortized over a twelve-month
period. Revenues from the packs are allocated between products and event
admission based on the proportionate average fair value of these items.
Allocated event revenue from the sales of these packs was approximately
$906,000, $471,000 and $423,000 in 1997, 1998 and 1999, respectively. The
allocated event revenues are amortized over a twelve-month period. Total net
deferred revenue was $662,176 and $844,649 at December 31, 1998 and 1999,
respectively. Substantially all product sales are made to Associates at a
published wholesale price. Net sales also reflect product returns and any
related refunds.

Accounting for Stock-based Compensation

  The Company uses Statement of Financial Accounting Standards No. 123 ("FAS
123"), "Accounting for Stock-Based Compensation," for stock-based compensation
issued to nonemployees. FAS 123 requires that stock-based compensation be
measured by the fair value at the date of grant. The Company measures the cost
of stock-based compensation issued to employees and directors under Accounting
Principles Board Opinion 25, "Accounting for Stock Issued to Employees" ("APB
25"), and its related interpretations. The Company has provided pro forma
disclosures, as required by FAS 123, in Note 12 for stock-based compensation
accounted for under APB 25.

Advertising Costs

  Advertising and promotional expenses are included in selling and
administrative expenses and are charged to operations when incurred.
Advertising and promotional expenses were approximately $2,241,000, $3,821,000
and $3,621,000 for 1997, 1998 and 1999, respectively. Literature and
promotional items, called sales aids, are sold to Associates to support their
sales effort and are included in inventories and charged to cost of sales when
sold.

Research and Development Costs

  The Company expenses research and development costs when incurred. Research
and development costs related to specific clinical studies, quality assurance
programs and new product development were approximately $381,000, $391,000 and
$438,000 in 1997, 1998 and 1999, respectively. Research and development costs
related to conceptualizing new products, enhancing existing products, Food and
Drug Administration compliance studies, general supplies, internal salaries
and consulting fees were approximately $3,008,000, $3,365,000 and $3,623,000
in 1997, 1998 and 1999, respectively. Salaries are included in selling and
administrative expenses and all other research and development costs are
included in other operating expenses in the accompanying consolidated
financial statements.

Software Development Costs

  The Company capitalizes qualifying costs relating to the development of
internal use software pursuant to Statement Of Position No. 98-1 "Accounting
for the Costs of Computer Software Developed or Obtained for Internal Use"
("SOP 98-1"). SOP 98-1 requires capitalization of qualifying costs after the
conceptual

                                     F-10


                            MANNATECH, INCORPORATED

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

formulation stage has been completed, and such costs are amortized over the
estimated useful life of the software, which is estimated at five years.
Capitalized costs totaled $1,713,000, $929,000 and $1,673,000 in 1997, 1998
and 1999, respectively. Amortization expense related to capitalized software
totaled $0, $346,000 and $528,000 in 1997, 1998 and 1999, respectively.

Earnings per Share

  The Company calculates earnings per share pursuant to Statement of Financial
Accounting Standards No. 128, "Earnings per Share" ("FAS 128"). FAS 128
requires dual presentation of basic and diluted earnings per share ("EPS") on
the face of the consolidated statement of income for all entities with complex
capital structures and requires a reconciliation of the numerator and
denominator of the basic EPS computation to the numerator and denominator of
the diluted EPS computation. Basic EPS calculations are computed using the
weighted-average number of common shares outstanding during the period, while
diluted EPS calculations are calculated using the weighted-average number of
common shares and dilutive common share equivalents outstanding during each
period.

Concentrations of Credit Risk

  Financial instruments, which potentially subject the Company to
concentrations of credit risk, consist principally of cash, cash equivalents,
investments and receivables from related parties. The Company utilizes
financial institutions, which the Company considers to be of high credit
quality. The Company believes its notes receivables from shareholders, at
December 31, 1999, are fully collectible.

Fair Value of Financial Instruments

  The fair value of the Company's financial instruments, including cash and
cash equivalents, notes receivable, notes payable, capital leases, payable to
affiliates and accrued expenses, approximate their recorded values due to
their relatively short maturities.

Foreign Currency Translation

  The Australian and the United Kingdom subsidiaries' functional currency is
the United States dollar. Nonmonetary assets and liabilities are translated at
historical rates, monetary assets and liabilities are translated at exchange
rates in effect at the end of the year, and income statement accounts are
translated at average exchange rates for the year. Translation (gains) and
losses of our foreign subsidiaries totaled $16,541 and ($175,564) in 1998 and
1999 respectively, and are included, in other expense, in the consolidated
statements of income.

Commissions

  Associates are paid commissions, which are based on direct and indirect
commissionable sales, downline growth and training of Associates. Commissions
are accrued when earned and generally paid at various times within the
following month.

Reclassification

  Certain prior years' balances have been reclassified to conform to the 1999
consolidated financial statement presentation.

NOTE 2 INITIAL PUBLIC OFFERING

  On February 12, 1999, the Company completed an initial public offering, (the
"Offering") on the Nasdaq National Market under the symbol "MTEX". In the
Offering, the Company and certain selling shareholders sold an aggregate of
3,056,016 shares of common stock, par value $0.0001 per share, at a price of
$8.00 per share. Of the total shares sold, 1,500,000 were sold by the Company,
yielding gross proceeds to the Company of $12,000,000. The net proceeds to the
Company were $9,240,958 after deducting deferred offering costs of $1,963,431,
legal, accounting, printing and other costs of approximately $406,385, and the
fee to the placement agent involved in the Offering of $389,226, net of
reimbursement of $90,774 in expenses by the placement agent.

  The selling shareholders sold 1,556,016 shares of common stock, yielding
gross proceeds of $12,448,128. The net proceeds paid to the selling
shareholders were $11,950,203, after deducting the fee to the placement agent
of approximately $497,925.

NOTE 3 INVESTMENTS

  The Company accounts for investments in accordance with the provisions of
Statement of Financial Accounting Standards No. 115 "Accounting for Certain
Investments in Debt and Equity Securities" ("FAS 115"). Under FAS 115, debt
securities that have readily determinable fair values are to be classified in
three categories: held-to-maturity, trading securities and available for sale.
Investments that the Company has the intent and the ability to hold to
maturity are carried at amortized cost. The amortized cost of debt securities
are classified as held-to-maturity and adjusted for amortization of premiums
and accretion of discounts. Realized gains and losses on sales of securities
are included in other expense, net in the statements of income.

  At December 31, 1999, investments consist of obligations of United States
Government sponsored enterprises, which are classified as held-to-maturity,
and include the following:

  During 1999, the Board of Directors of the Company's wholly-owned
subsidiary, Internet Health Group, Inc.'s ("IHG"), approved their 1999
Incentive and Nonstatutory Stock Option Plan ("IHG Plan"). Under the IHG Plan,
a total of 1,500,000 shares of IHG's common stock, par value $0.0001 per share
was reserved for issuance. During 1999, IHG granted 1,258,750 incentive stock
options to various employees and to the executive officers of the Company. The
stock options are exercisable at $0.27 per share, which was the estimated fair
value on the date of grant. The options are exercisable over three years
beginning on July 10, 2000. As of December 31, 1999 none of these options were
exercised or canceled. The weighted-average fair value of options granted
during 1999 was $0.15 per share and the weighted-average remaining contractual
life was 9.8 years.

  The following table summarizes information with respect to options
outstanding and exercisable at December 31, 1999:

  For both IHG and Mannatech stock option plans, incentive stock options
granted to employees are valued using the intrinsic method, are
nontransferable and are granted for terms no longer than ten years and at a
price which may not be less than 100% of the fair value of the common stock on
the date of grant. For purposes of pro forma disclosures, the estimated fair
values of the options are amortized to expense over the vesting period. The
Company's pro forma information follows:

  The fair value of each option granted was estimated on the date of grant
using the Black-Scholes option pricing model with the following weighted-
average assumptions during 1997, 1998 and 1999:



                                                               1997  1998  1999

  Under the Stock Option Plans, nonqualified stock options granted to
nonemployees are valued using the fair value method, are nontransferable and
are granted for terms no longer than six years and at a price which may not be
less than 100% of the fair value of the common stock on the date of grant.
During 1997, the Company issued 356,000 nonqualified stock options to
nonemployees at an exercise price of $1.35 per share. Additionally, the
Company issued 100,000 nonqualified stock options in July 1997. These options
are priced at $2.00, vest immediately, are exercisable after one year and have
a term of six years.

  During 1997, compensation expense of $155,503 was included in other
operating expenses for the nonemployee options. This expense was determined by
calculating the fair value of options granted on the date of grant using the
Black-Scholes option-pricing model and the following weighted-average
assumptions:

  During 1997, the Company granted a consulting firm 475,015 warrants to
purchase the same number of shares of the Company's common stock. These
warrants were nontransferable and vested as follows: 178,125 shares at
issuance and 26,990 each month through March 1, 1998. The warrants were
exercisable at $1.35 per share and were to expire on the earlier of May 1,
2003 or thirty-six months after the underlying shares were

registered for public resale under the Securities Act. At December 31, 1998,
all of the warrants were vested and in February 1999, all of these warrants
were exercised.

  As a provision of the warrant agreement, the consulting firm could require
the Company to repurchase the outstanding warrants between May 1998 and May
1999 for $300,000. Accordingly, it was determined that the fair value of the
warrants as of December 31, 1998 was $300,000.

NOTE 13 COMMITMENTS AND CONTINGENCIES

  The Company leases certain office space, automobiles and equipment under
various noncancelable operating leases, and has options to renew and
renegotiate most of the leases. The leases expire at various times through
January 2008. The Company also leases equipment under various month-to-month
cancelable operating leases. Total rent expense was approximately $702,000,

  Effective September 1, 1998, the Company entered into various employment
agreements with six of its executives. The employment agreements are for five
years with a specified minimum salary and are extended automatically each year
for one additional year unless both parties agree to termination prior to the
end of any term. On November 1, 1999, the Company entered into an employment
agreement with another one of its executives. This agreement expires in
October 2002. The agreements can be canceled by either party; however, if
canceled without cause, by the Company, the Company is required to pay the
minimum salary for the life of the agreement. In 1995 and 1996, the Company
entered into various cancelable employment agreements with some of its key
employees which provide for minimum annual salaries based on sales volume. In
1997 the Company terminated several of these contracts. As a result of the
terminations, the Company incurred approximately $499,000 in severance
charges.

  The Company has a commitment with a supplier to purchase raw materials
through August 2000. On January 12, 2000, the Company extended this commitment
for an additional two years. The purchase commitment with this supplier is
approximately $5.6 million, $7.9 million and $4.6 million for 2000, 2001 and
2002, respectively.

  The Company utilizes royalty agreements with individuals or entities to
provide compensation for items such as reprints of articles or speeches
relating to the Company; sales of promotional videos featuring sports
personalities and promotional efforts in product sales or attracting new
Associates. In addition, in 1997 until August 1998, the Company paid a monthly
fee of $20,000 to a research foundation for promoting and conducting health
studies of Associates. The total expenses for all of these agreements were
approximately $1,568,000, $933,000 and $416,000 in 1997, 1998 and 1999,
respectively.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

  In 1998, the Company paid $295,000 for any possible sales tax assessment
from a certain state comptroller, including any applicable interest by the
state agency. In 1999, the sales tax audit was completed and the Company was
refunded approximately $135,000 related to the 1998 assessment. The expense
and refund was included in operating expenses in the consolidated financial
statements.

  In October 1999, the Company entered into an agreement with a shareholder
and a high level Associate where the Associate will promote the Company and
begin the development of downline growth in Japan. Under the terms of the
agreement, the Company will pay the Associate $50,000 a month plus all
expenses for two years. The Associate can also earn additional commissions of
up to $1,600,000 for the development and sale of training materials and sales
aids. During 1999, the Company accrued $206,000 of which $106,000 remained
unpaid at December 31, 1999.

NOTE 14 CAPITAL TRANSACTIONS

 Stock Split

  On May 14, 1997, the Board of Directors declared a 1,000-for-1 stock split
of the Company's common stock. The Board also approved a change in the stated
par value of common shares from $0.01 per share to $0.0001 per share, and
increased the number of authorized shares to 100,000,000. All share and per
share data have been retroactively adjusted for this split.

 Preferred Stock

  On April 8, 1998, the Company amended its Articles of Incorporation to
reduce the number of authorized shares of common stock from 100,000,000 to
99,000,000. Additionally, the Company has authorized 1,000,000 shares of
preferred stock with a par value of $0.01 per share.

 Treasury Stock

  During 1999, three of the Company's existing shareholders tendered 16,308
shares of their common stock, to the Company, at the current market price on
the date of transfer, to exercise 150,074 stock options at $1.35 per share.
The Company recorded these shares received as treasury stock.

NOTE 15 LITIGATION

  On February 29, 2000, a class action lawsuit was filed in District Court,
County of Boulder, Colorado; naming the Company and three other companies as
co-defendants. The other companies were involved in selling of certain health
benefits program offered to the Company's Associates. The suit alleged the
defendants were marketing and selling illegal health insurance policies,
committed fraud and failed to pay benefits under such policies, which caused
economic loss to the plaintiffs and others. The suit seeks a trial by jury and
an unspecified amount of damages. The Company believes it has valid defenses
and that the allegations are completely without merit. The Company intends to
vigorously defend its position. Nevertheless, an adverse resolution to this
matter might have a material adverse effect on the Company's business, results
of operations, financial condition and liquidity.

  The Company has several other pending claims incurred in the normal course
of business which, in the opinion of management, can be resolved without
material affect on the Company's consolidated results of operations or
consolidated financial condition.

  At December 31, 1999, 1,367,500 common stock options were excluded from the
dilutive EPS calculation as the option exercise price was greater than the
average market price of the common stock. The effect of such inclusion in the
EPS calculation would be to increase the income per share.

           NON-QUALIFIED STOCK OPTION FOR NON-EMPLOYEE DIRECTORS AND
                                  CONSULTANTS

To:            STEVEN A. BARKER
     ----------------------------------------------------------
     Name

            914 Drehr Avenue, Baton Rouge, LA  70806
     ----------------------------------------------------------
     Address

Date of Grant:             October 19, 1999
              ----------------------------------------------------------

  You are hereby granted an option, effective as of the date hereof, to purchase
50,000 shares of common stock, $0.0001 par value per share ("Common Stock"), of
Mannatech, Incorporated, a Texas corporation (the "Company") at a price of
$7.6875 per share pursuant to the Company's 1997 Stock Option Plan (the "Plan").

  Your option may first be exercised ninety (90) days following completion by
the Company of a registered public offering of its securities pursuant to the
requirements of the Securities Act of 1933, as amended.  Thereafter, your option
may be exercised for up to 100% of the total number of shares, subject to this
Option (as adjusted for stock dividends, stock splits, combinations of shares
and what the Committee deems in its sole discretion to be similar
circumstances).

  You may exercise your option by giving written notice to the Secretary of the
Company on forms supplied by the Company at its then principal executive office,
accompanied by payment of the option price for the total number of shares you
specify that you wish to purchase. The payment may be in any of the following
forms: (a) cash, which may be evidenced by a check and includes cash received
from a stock brokerage firm in a so-called "cashless exercise"; (b) (unless
prohibited by the Committee) certificates representing shares of Common Stock of
the Company, which will be valued by the Secretary of the Company at the fair
market value per share of the Company's Common Stock (as determined in
accordance with the Plan) on the date of delivery of such certificates to the
Company, accompanied by an assignment of the stock to the Company; or (c)
(unless prohibited by the Committee) any combination of cash and Common Stock of
the Company valued as provided in clause (b). Any assignment of stock shall be
in a form and substance satisfactory to the Secretary of the Company, including
guarantees of signature(s) and payment of all transfer taxes if the Secretary
deems such guarantees necessary or desirable.

  Your option will terminate at 5:00 p.m., October 19, 2005 ("Termination Date).


  In the event of any change in the outstanding shares of the Common Stock of
the Company by reason of a stock dividend, stock split, combination of shares,
recapitalization, merger,


consolidation, transfer of assets, reorganization, conversion or what the
Committee deems in its sole discretion to be similar circumstances, the number
and kind of shares subject to this option and the option price of such shares
shall be appropriately adjusted in a manner to be determined in the sole
discretion of the Committee.

  This option is not transferable otherwise than by will or the laws of descent
and distribution, and is exercisable during your lifetime only by you,
including, for this purpose, your legal guardian or custodian in the event of
disability. Until the option price has been paid in full pursuant to due
exercise of this option and the purchased shares are delivered to you, you do
not have any rights as a shareholder of the Company. The Company reserves the
right not to deliver to you the shares purchased by virtue of the exercise of
this option during any period of time in which the Company deems, in its sole
discretion, that such delivery would violate a federal, state, local or
securities exchange rule, regulation or law.

  Notwithstanding anything to the contrary contained herein, this option is not
exercisable until all the following events occur and during the following
periods of time:

            a. Until the Plan pursuant to which this option is granted is
approved by the shareholders of the Company in the manner prescribed by the Code
and the regulations thereunder, except that options granted to Consultants need
not have shareholder approval;

            b. Until the issuance of the underlying shares are approved and/or
registered with such federal, state and local regulatory bodies or agencies and
securities exchanges as the Company may deem necessary or desirable; or

            c.  During any period of time in which the Company deems that the
exercisability of this option, the offer to sell the shares optioned hereunder,
or the sale thereof, may violate a federal, state, local or securities exchange
rule, regulation or law, or may cause the Company to be legally obligated to
issue or sell more shares than the Company is legally entitled to issue or sell;
or

            d. Until you have paid or made suitable arrangements to pay (which
may include payment through the surrender of Common Stock, unless prohibited by
the Committee) and respecting employees of the Company only (i) all federal,
state and local income tax withholding required to be withheld by the Company in
connection with the option exercise and (ii) the employee's portion of other
federal, state and local payroll and other taxes due in connection with the
option exercise.

  The following two paragraphs shall be applicable if, on the date of exercise
of this option, the issuance of the Common Stock to be purchased pursuant to
such exercise has not been registered under the Securities Act of 1933, as
amended, and under applicable state securities laws, and shall continue to be
applicable for so long as such registration has not occurred:

            (a) The optionee hereby agrees, warrants and represents that he will
acquire the Common Stock to be issued hereunder for his own account for
investment purposes only, and not with a view to, or in connection with, any
resale or other distribution of any of such


shares, except as hereafter permitted. The optionee further agrees that he will
not at any time make any offer, sale, transfer, pledge or other disposition of
such Common Stock to be issued hereunder without an effective registration
statement under the Securities Act of 1933, as amended, and under any applicable
state securities laws or an opinion of counsel acceptable to the Company to the
effect that the proposed transaction will be exempt from such registration. The
optionee shall execute such instruments, representations, acknowledgements and
agreements as the Company may, in its sole discretion, deem advisable to avoid
any violation of federal, state, local or securities exchange rule, regulation
or law.

            (b) The certificates for Common Stock to be issued to the optionee
hereunder shall bear the following legend:

  "The shares represented by this certificate have not been registered under the
Securities Act of 1933, as amended, or under applicable state securities laws.
The shares have been acquired for investment and may not be offered, sold,
transferred, pledged or otherwise disposed of without an effective registration
statement under the Securities Act of 1933, as amended, and under any applicable
state securities laws or an opinion of counsel acceptable to the Company that
the proposed transaction will be exempt from such registration."

  The foregoing legend shall be removed (i) upon any sale of such shares
pursuant to an effective registration statement under the Securities Act of
1933, as amended, or Rule 144 promulgated under the Securities Act of 1933, as
amended, or (ii) at such time as such shares become eligible for resale under
Rule 144(k) promulgated under the Securities Act of 1933, as amended.

  The sole purpose of the agreements, warranties, representations and legend set
forth in the two immediately preceding paragraphs is to prevent violations of
the Securities Act of 1933, as amended, and any applicable state securities
laws.

  It is the intention of the Company and you that this option shall not be an
"Incentive Stock Option" as that term is used in Section 422 of the Code and the
regulations thereunder.

  Any dispute or disagreement between you and the Company with respect to any
portion of this option or its validity, construction, meaning, performance or
your rights hereunder shall be settled by arbitration in accordance with the
Commercial Arbitration Rules of the American Arbitration Association or its
successor, as amended from time to time. However, prior to submission to
arbitration you will attempt to resolve any disputes or disagreements with the
Company over this option amicably and informally, in good faith, for a period
not to exceed two weeks. Thereafter, the dispute or disagreement will be
submitted to arbitration. At any time prior to a decision from the arbitrator(s)
being rendered, you and the Company may resolve the dispute by settlement. You
and the Company shall equally share the costs charged by the American
Arbitration Association or its successor, but you and the Company shall
otherwise be solely responsible for your own respective counsel fees and
expenses. The decision of the arbitrator(s) shall be made in writing, setting
forth the award, the reasons for the decision and award and shall be binding and
conclusive on you and the Company. Further, neither you nor the Company shall
appeal any such award. Judgment of a court of competent jurisdiction may be
entered upon the award and may be enforced as such in accordance with the
provisions of the award.

  This option shall be subject to the terms of the Plan in effect on the date
this option is granted, which terms are hereby incorporated herein by reference
and made a part hereof. In the


event of any conflict between the terms of this option and the terms of the Plan
in effect on the date of this option, the terms of the Plan shall govern. This
option constitutes the entire understanding between the Company and you with
respect to the subject matter hereof and no amendment, supplement or waiver of
this option, in whole or in part, shall be binding upon the Company unless in
writing and signed by the President of the Company. This option and the
performances of the parties hereunder shall be construed in accordance with and
governed by the laws of the State of Texas.

  Notwithstanding any provision contained herein to the contrary, you agree to
be bound by the underwriting agreements or requirements by and between
Mannatech, Inc. and any Underwriter which might provide services to it in
connection with any public offering of its capital stock ("Underwriter").
Further, should such Underwriter impose any restrictions upon the exercise,
registration or other rights, concerning the option upon the shares of stock
conferred hereby, otherwise granted under this Agreement, you agree to further
be bound by such requirements, limitations, restrictions, and/or agreements, as
agreed to by Mannatech.  You hereby appoint Mannatech as your attorney-in-fact
to execute all documents on your behalf concerning agreements offering the
and/or shares of stock which are the subject of the option conferred hereby,
including, without limitation, those agreements with the Underwriter, referenced
above.

  Please sign the copy of this option and return it to the Company's secretary,
thereby indicating your understanding of and agreement with its terms and
conditions.

Dear Mr. Turner:

     This will confirm our understanding in principle related to  the extension

"Agreements") executed by and between Mannatech(TM) Incorporated ("Mannatech")
and Caraloe, Incorporated ("Caraloe") on August 14, 1997, (hereinafter
collectively, the "Parties") both Agreements to be incorporated by reference as
part of this Agreement. It is the intent of the Parties hereto that the
Agreements shall remain in full force and effect with the exception of that

("Terms and Conditions") as outlined herein.

     The term of the Agreements shall be extended for a two - (2) year period,

     Mannatech agrees to purchase from Caraloe, and Caraloe agrees to

month, but in any event not more than as indicated on the attached Exhibits as

  WHEREAS, in conjunction with the Employee's hiring and subsequent access to
and use of the CONFIDENTIAL INFORMATION and trade secrets of the Employer, the

                                       1


                                   ARTICLE I

                                  ARTICLE II

                 DUTIES, NON-COMPETITION and NON-SOLICITATION

  1.   Employee agrees to serve in the position of Executive Vice President and
Chief Operating Officer for Domestic Operations, or such other position as the
parties may hereafter agree during the term of this agreement, and to perform
diligently and to the best of Employee's abilities the duties and services
appertaining to such offices, as well as such additional duties and services
appropriate to such office upon which the parties mutually may agree from time-
to-time or as shall be designated by the Board of Directors.  The Employee also
agrees that his employment is subject to the current and future policies and
procedures maintained and established by the Employer.  The Employee shall
devote the Employee's full productive time, best efforts, ability and attention
to the business of the Employer and the performance of the Employee's duties.

  2.  Employee acknowledges and understands that from time to time the
Employee's duties may require the Employee to work on-site at a non-company
location.  In such instance, the Employee agrees to comply with all of the
policies, procedures and directives relevant to working at such non-company
location.

  3.  Employee represents and admits that in the termination of the Employee's
employment for any reason whatsoever, the Employee's experiences and
capabilities are such that the Employee can obtain employment in business
engaged in other lines and/or of a different nature, and that the enforcement of
a remedy by way of injunction will not prevent the Employee from earning a
livelihood.

  4.  Employee acknowledges that the Employee will receive special knowledge and
specialized training from the Employer, included in which is the CONFIDENTIAL
INFORMATION identified in Article III below.  The Employee further acknowledges
that training provided by the Employer and the CONFIDENTIAL INFORMATION is
valuable to the Employer and, therefore, the Employer's investment in the
training and the protection and maintenance of the CONFIDENTIAL INFORMATION
constitutes a legitimate interest to be protected by the Employer by the
covenant not to compete, set forth in Article II of this Agreement.

  5.   Non-Competition.   The Employee therefore agrees that for a period of one
(1) year after the Employee shall cease to be employed by the Employer for any
reason, the Employee shall not engage in any form of business which is
competition with the Employer, including through the business of any person,
company, firm, corporation, partnership, association, agency, or business, and
particularly through a party known to the Employee to be an independent contract
sales associate and/or customer of the Employer or with whom the Employee had
contact during, or by reason of, the Employee's employment by the Employer.

                                       3


  6.  Non-Solicitation.  The Employee further agrees that for a period of one
(1) year after the Employee shall cease to be employed by the Employer for any
reason, the Employee will not, either directly or indirectly, through any
person, firm, association or corporation with which the Employee, customer
and/or independent contractor sales associate ("Subject Person") is now or may
hereafter become associated with, solicit, cause, influence or induce any
present or future Subject Person of the Employer or its affiliates to leave the
employ or business relationship with the Employer or its affiliates to accept
employment or a business relationship with the Employee or with such person,
firm, association, or corporation with whom the Employee may then be affiliated.

  As set forth above, the Employee acknowledges that the foregoing non-
competition and non-solicitation covenants are ancillary to or a part of an
otherwise enforceable agreement, such being the general agreement of Employment
and its related agreements concerning confidentiality and non-disclosure of
CONFIDENTIAL INFORMATION and non-solicitation, at the time that this non-
competition covenant is made, that the limitations as to time defined herein are
reasonable and do not impose a greater restraint than is necessary to protect
the goodwill or other business interests of the Employer, that the limitations
as to geographic area defined herein are reasonable and do not impose a greater
restraint than is necessary to protect the goodwill or other business interests
of the Employer, and that the scope of activity to be restrained defined herein
is reasonable and does not impose a greater restraint than is necessary to
protect the good will or other business interests.

  7.  Employee agrees that in the highly competitive business in which the
Employer is engaged, personal contact is of primary importance in securing new
and retaining present Associates and customers.  The Employee also agrees that
the Employer has a legitimate interest in maintaining its relationships with its
Associates and customers and that it would be unfair for the Employee to solicit
the business of the Employer's Associates and customers and exploit the personal
relationships the Employee develops with the Employer's Associates and customers
by virtue of the Employee's access to the Employer's customers as a result of
the Employee's employment by the Employer.

  8.  The foregoing covenants not to compete and solicit shall not be held
invalid or unenforceable because of the scope or the territory or actions
subject thereto or restricted thereby, or the period of time within which such
Agreement is operative; but an award or decree in arbitration or any judgment of
a court of competent jurisdiction, as the case may be, may define the maximum
territory and actions subject thereto and restricted by this Article II and the
period of time during which the Agreement is enforceable.  Any alleged breach of
other provisions of this Agreement asserted by the Employee shall not be a
defense for the Employee to claims arising from the Employer's enforcement of
the provisions of this paragraph.  Should the Employee violate the non-
competition, non-solicitation covenants of this Article II, then the period of
time for these covenants shall automatically be extended for the period of time
from which the Employee began such violation until the Employee permanently
ceases such violation.

                                       4


  9.  Irrespective of the term of employment under this Agreement, and in
consideration of the promises specified in Article II of this Agreement, the
Employer agrees as follows:

  a.  To provide specialized training as specified herein; and

  b.  To provide the Employee with access to the Employer's software and files,
records, marketing procedures, processes, computer programs, compilations of
information, records, Associate and client requirements, pricing techniques,
lists, formulae, lists identifying Associates, partners, potential investors,
methods of doing business and other CONFIDENTIAL INFORMATION which is regularly
used in the operation of the business of the Employer.

  10.  Employee represents and warrants that the delivery and execution of this
agreement will not cause a breach in the terms of any existing agreement to
which he is a party nor interfere with any undertakings which he is bound to
perform or refrain from under any such agreements.

  11.  Article II, Paragraphs 5 and 6 shall survive the execution, performance
and/or termination of this Agreement, subject to the time and scope limitations
set forth therein.


                                  ARTICLE III
                           CONFIDENTIAL INFORMATION

  1.  The Employer will provide or has provided the Employee with specialized
information concerning the products and the business operations of the Employer.
Irrespective of the term of employment, and in consideration of the Employee's
promises specified in Article II of this Agreement, the Employer agrees to
provide specialized training and instruction to the Employee for the job duties
assigned to the Employee, and agrees to provide specialized training to the
Employee for such additional job duties as the Employer may, in good faith,
direct or as the interests, needs and business opportunities of the Employer
shall require or make advisable.

  2.  During the course of the Employee's employment and training incident
thereto the Employee will be or was given access to the Employer's CONFIDENTIAL
INFORMATION concerning Products and the business operations of the Employer.

  3.  The Employee acknowledges that in the further course of the Employee's
employment with the Employer, the Employee will gain a close, personal and
special influence with the Employer's customers and will be acquainted with all
of the Employer's business, particularly the Employer's CONFIDENTIAL INFORMATION
concerning the business of the Employer and its affiliates.

  4.  For purposes of this Agreement "CONFIDENTIAL INFORMATION" shall mean and
include information disclosed to the Employee or known by the Employee through
the

                                       5


Employee's employment with the Employer, not generally known in the Employer's
industry, about the Employer's products, processes and services, including but
not limited to information concerning inventions, trade secrets, research and
development, as well as all data or information concerning customers (including,
Associates), customer lists (including downline reports and similar reports of
business activities and relevant information concerning persons who conduct the
same), prospect lists, mailing lists, sales leads, contracts, financial reports,
sales, purchasing, price lists, product costs, marketing programs, marketing
plans, business relationships, business methods, accounts payable, accounts
receivable, accounting procedures, control procedures and training materials.

  5.  The Employee recognizes that the Employee's position with the Employer is
one of the highest trust and confidence by reason of the Employee's access to
the CONFIDENTIAL INFORMATION and the Employee agrees to use the Employee's best
efforts and will exercise utmost diligence to protect and safeguard the
CONFIDENTIAL INFORMATION.  In this respect, the Employee agrees that fulfilling
the obligations of the Agreement is part of the Employee's job responsibilities
with the Employer for which the Employee has been retained as an Employee and
for which the Employee has received consideration therefor.

  6.  Except as may be required by the Employer in connection with and during
the Employee's employment with the Employer, or with the express written
permission of the Employer, the Employee shall not, either during the Employee's
work as an employee with the Employer or at any time thereafter, directly or
indirectly, download, printout, copy, remove from the premises of the Employer,
use for the Employee's own benefit or for the benefit of another, or disclose to
another, any CONFIDENTIAL INFORMATION of the Employer, its customers,
contractors or other with which the Employer has a business relationship.

  7.  Employee agrees that all files, memoranda, data, notes, records, drawings,
charts, graphs, analyses, letters, reports, or other documents or similar items
made or compiled by the Employee, made available to the Employee or otherwise
coming into the Employee's possession while employed by the Employer concerning
any process, apparatus or products manufactured, sold, used, developed,
investigated or considered by the Employer concerning the CONFIDENTIAL
INFORMATION or concerning any other business or activity of the Employer shall
remain at all times the property of the Employer and shall be delivered to the
Employer upon termination of the Employee's employment with the Employer or at
any other time upon request.

  8.  The Employee agrees that, during the term of the Employee's employment
with the Employer or upon termination thereof, and if requested by the Employer
to do so, the Employee will sign an appropriate list of any and all CONFIDENTIAL
INFORMATION  of the Employer of which the Employee has knowledge or about which
the Employee has acquired information.

9.  This Article 9 shall survive the execution, performance and/or termination
of this

                                       6


Agreement.

                                  ARTICLE IV
                           ASSIGNMENT OF INVENTIONS

  1.  The Employee agrees to promptly disclose to the Employer and Employee
hereby assigns to the Employer or its designee, its assigns, successors or legal
representatives, all, right, title and interest in and to any and all patents,
formulae, inventions, processes, designs, software, firmware, circuitry,
diagrams, copyrights, trade secrets, and any other proprietary information
(collectively, the "Proprietary Information") whatsoever, conceived, developed
or completed by the Employee during the course of the Employee's employment with
the Employer, or using the Employer's time, data, facilities and/or materials,
provided the subject matter of the Proprietary Information is within the scope
of the duties and responsibilities of one in the Employee's position with the
Employer or occurs as a result of the Employee's knowledge of a particular
interest of the Employer.

  2.  The Employee agrees to assist the Employer at any time during the
Employee's employment with the Employer, or after termination of the Employee's
employment by the Employer with reimbursement by the Employer for all expenses
incurred, in the preparation, execution, and delivery of any assignments,
disclosures, patent applications, or papers within the scope and intent of this
Agreement required to obtain patents or copyrights in the Proprietary
Information in this or a foreign country and in connection with such other
proceedings as may be necessary to vest title to the Proprietary Information in
the Employer, its assigns, successors, or legal representatives.

                                   ARTICLE V
                                 MISCELLANEOUS

  1.  Termination.  Nothing contained in this Agreement shall be construed as
impairing the right of the Employer to terminate the Employee's employment with
the Employer hereunder, provided that Employer shall be liable to compensate the
Employee as follows:

          a.   By continuing to pay his base salary, set forth in Article I,
               paragraph II through October 31, 2002 on the usual and customary
               pay dates of the Corporation, falling every other week; provided,
               however, should October 31, 2002 fall between pay periods, the
               amount due the Employee shall be paid to him on October 31, 2002
               as the final amount due under this provision.  In the sole
               discretion of the Employer, at the request of the Employee, a
               lump sum payment of the amounts that are to become due under the
               terms of this Article V, Paragraph 1.a. in the instance of
               termination of the Employee prior to the end of the term of this
               Agreement, may be paid in a lump sum, which sum shall be
               discounted by that percentage rate which is the then prevailing,
               and in effect, interest rate

                                       7


               for a United States Treasury Security, having a maturity of three
               (3) years, publicly quoted during the week in which the
               termination, if any, occurred. Should such treasury security
               cease being sold, offered or quoted, the parties, in good faith,
               shall select an equivalent index or discount rate by which to
               make the discount computation;

          b.   By delivering to the Employee, Stock Options, if any, he would
               have earned as awarded by any resolution of the Board of
               Directors or the compensation respecting that calendar year in
               which termination, if any, ensued, identical in vesting and
               terms, but with the awarded number of option shares being reduced
               ratably based upon the period of service of the Employee prior to
               termination, compared with twelve months' service;

          c.   By paying, to the Employee, when all similar bonuses are paid in
               the next calendar year, respecting that calendar year in which
               termination, if any, ensued, that bonus he would have earned, if
               any, had he remained employed by the Employer, reduced ratably
               based on the period of service of the Employee prior to
               termination, compared with twelve months' service.

(For computational purposes, termination during days 1-15 of the month shall not
count as that month's service; however, termination during days 16 through and
up to 31, shall count as that month's service.)

  2.  Obligations.  The Employee's obligations under this Agreement shall
continue, survive and remain enforceable in accordance with the terms hereof,
whether or not the Employee's employment with the Employer shall be terminated
voluntarily or involuntarily, with or without reason.

  3.  Future Agreement.  Should this Agreement expire in accordance with its
      -----------------
terms with the Employee within the employment of the Employer, the parties will
renew this Agreement on terms and conditions similar to other employees of equal
title and position within the Employer's organization.

  4.  Enforcement.  It is the express intention of the parties to this Agreement
to comply with all laws applicable to the covenants and provisions contained in
this Agreement.  If any of the covenants contained in this Agreement are found
to exceed in duration or scope those permitted by law, it is expressly agreed
that such covenant may be reformed or modified by the award or decree of an
arbitrator, or, if applicable, a final judgment of a court of competent
jurisdiction or other lawful constituted authority, as the case may be, to
reflect a lawful and enforceable duration or scope, and such covenant
automatically shall be deemed to be amended and modified so as to comply with
the arbitration award, decree, judgment or order of such court or authority, as
the case may be.  If any one or more of the provisions contained herein shall
for

                                       8


any reason be held invalid, illegal or unenforceable in any respect even after
reformation, such invalidity, illegality or unenforceability shall not affect
the enforceability or validity of any other provision contained in this
Agreement, and this Agreement shall be construed as if such invalid, illegal, or
unenforceable provisions had never been contained herein.

  5.  Adequacy of Consideration; Separate Agreements.  The Employee agrees that
the agreements, non-competition agreements, nondisclosure agreements, and non-
solicitation agreements set forth herein each constitute separate agreements,
independently supported by good and adequate consideration and shall be
severable from the other provisions of this Agreement and shall survive the
Agreement.  The existence of any claim or cause of action of the Employee
against the Employer, whether predicated on this agreement or otherwise, shall
not constitute a defense to the enforcement by the Employer of the covenants and
agreements of the Employee contained in the non-competition, nondisclosure or
the non-solicitation agreements.  If a court of competent jurisdiction
determines that any restriction in a clause or provision of this Agreement is
void, illegal or unenforceable, the other clauses and provisions of this
Agreement shall remain in full force and effect and the clauses and provisions
that are determined to void, illegal or unenforceable shall be limited so that
they shall remain in effect to the fullest extent permitted by law.

  6. No Indirect Breach.  The Employee will use his best efforts to ensure that
no relative of his, nor any corporation or other entity or which he is a
officer, principal, manager, director or shareholder or other affiliate, shall
take any action that the Employee could not take without violating any provision
of this Agreement.

  7.  Injunctive Relief.  The Employee recognizes and acknowledges that damages
in the event of his breach of certain provisions of this Employment Agreement
would be inadequate, and the Employee agrees that the Employer, in addition to
all other remedies it may have, shall have the right to injunctive relief via
arbitration if there is a breach by the Employee of any one or more of the
provisions contained in Article II hereof.

  8.  Arbitration.  Arbitration, including the right to invoke injunctive relief
and any emergency relief or measures provided for, shall be the exclusive remedy
for any and all disputes, claims or controversies, whether statutory,
contractual or otherwise, between the Employer and the Employee concerning the
Employee's employment or the termination thereof.  In the event either party
provides a Notice of Arbitration of Dispute to the other party, the Employer and
the Employee agree to submit such dispute or controversy, whether statutory or
otherwise, to an arbitrator or arbitrators selected from a panel of arbitrators
of the American Arbitration Association located in Dallas, Texas.  The effective
rules at the time of the commencement of the of Commercial Arbitration of the
American Arbitration Association shall control the arbitration. In any
arbitration proceeding conducted subject to these provisions, all statutes of
limitations that would otherwise be applicable shall apply to any arbitration
proceeding hereunder.  In any arbitration proceeding conducted subject to these
provisions, the arbitrator(s) is/are specifically empowered to decided any
question  pertaining to limitations, and

                                       9


may do so by documents or by a hearing, in his or her sole discretion. In this
regard, the arbitrator may authorize the submission of pre-hearing motions
similar to a motion to dismiss or for summary adjudication for the purposes of
consideration this matter. The arbitrator's decision will be final and binding
upon the parties. The parties further agree to abide by and perform any award
rendered by the arbitrator. The prevailing party in such proceeding shall be
entitled to record and have awarded its reasonable attorney's fees, in addition
to any other relief to which it may be entitled. In rendering the award, the
arbitrator shall state the reasons therefor, including any computations of
actual damages or offsets, if applicable.

  9.  Waiver of Breach.  The waiver by any party hereto of a breach of any
provision of this Agreement shall not operate or be construed as a waiver of any
subsequent breach by any party.

  10.  Entire Agreement.  This Agreement contains the entire agreement of the
parties hereto.  no modification or amendment of this Agreement may be made
except by written agreement signed by both of the parties hereto.

  11.  Descriptive Headings.  All headings, captions and arrangements used in
this Agreement are intended solely for the convenience of the parties and shall
not be deemed to limit, amplify or modify the terms of this Agreement nor affect
the meaning thereof.

  12.  Governing Law.  The substantive laws of the State of Texas, excluding any
conflicts of law rule or principle that might otherwise refer to the substantive
law of another jurisdiction, shall govern the interpretation, validity and
effect of this Agreement without regard to the place for performance thereof.
This Agreement has been executed and delivered by the parties hereto in Dallas
County, Texas, and the Employer and the Employee agree that venue as to any
action  which might ensue after arbitration shall be proper, if permitted,
within the state or federal courts in Dallas County, Texas to decide any matter
relating to this Agreement or the related arbitration.
