PART I Item 1. Business General Mannatech, Incorporated, a Texas corporation, develops and sells proprietary nutritional supplements and topical products through a network marketing system. Mannatech operates in a single segment in which it sells its products in the United States, Canada, Australia, the United Kingdom and Japan through a network of approximately 237,000 active associates as of March 8, 2001 compared to approximately 269,000 active associates as of March 9, 2000. An "active" associate is one who has purchased products from Mannatech within the last 12 months. Mannatech focuses its development efforts primarily in the area of carbohydrate technology by creating its proprietary ingredient, Ambrotose(R) complex, which combines certain naturally occurring sugars required to support optimal cell-to-cell communication. Mannatech's products are primarily 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. Mannatech's 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. Mannatech markets its products exclusively through a network marketing system that it believes is well suited to its products, which emphasize health and nutrition. Mannatech believes network marketing appeals to a broad cross- section of the population, particularly those seeking to supplement family income, start a home-based business or pursue employment opportunities other than conventional, full-time employment, because it allows in-person product education not available through traditional marketing techniques. Mannatech completed the following during the past 12 months: . opened its Japan subsidiary on June 26, 2000; . closed operations of its Internet website subsidiary - Internet Health Group, Inc. - on December 29, 2000; . introduced ImmunoStart(TM) Chewables in October 2000; . introduced Glyco-Bears(TM), a children's multi-vitamin, in March 2001; . made various management changes, including hiring a new Chief Executive Officer, new Chief Information Officer and new President of International Operations; . appointed two new independent directors to its Board of Directors; . entered into a separation agreement with its former Chief Operating Officer, and . entered into a consulting agreement with its former President to provide various consulting services as the Global Vision Architect. Since its initial public offering, Mannatech's common stock has traded on the Nasdaq National Market under the symbol "MTEX." Information for each of Mannatech's most recent five fiscal years, with respect to the amounts of net sales, results of operations and identifiable assets is set forth in this report under Item 6. 2

Mannatech's principal executive offices are located at 600 S. Royal Lane, Suite 200, Coppell, Texas 75019, its telephone number is (972) 471-7400 and its website address is www.mannatech-inc.com. You can contact the Investor Relations department at (972) 471-6512 or IR@mannatech.com. Unless the context states otherwise, the term "Mannatech," "Company," "our," "we," "their" or "its" as used in this report shall mean Mannatech, Incorporated and all of its subsidiaries, collectively. Industry Overview Mannatech believes that the nutritional supplement industry targets two sub-industries: the wellness industry and the sickness or healthcare industry. The sickness or healthcare industry focuses on curing diseases, disorders and trauma whereas the wellness industry focuses on maintaining optimal health. Each sub-industry includes manufacturers and distributors of products that are generally intended to cure the symptom or disease and/or enhance the body's performance and contributes to optimal health and wellness. Nutritional supplements include: . vitamins; . minerals; . dietary supplements; . herbs; . botanicals; and . compounds derived from the above. In recent years, the nutritional supplement industry has experienced substantial growth. Mannatech believes the growth is a result of the following: . the adoption of the Dietary Supplement Health and Education Act of 1994, which allows vendors of dietary supplements to educate consumers regarding the effects of certain ingredients; . a widespread and growing interest and awareness among consumers on issues of diet, nutrition and health; . the continued rise in the introduction of new nutritional products in response to scientific research; . a boom in exercise and fitness activities, fitness facilities and stress management programs; . the world's developed economies and domestic economy that generates discretionary income and created an educated populace; . aging generations, particularly the baby-boomers, who are willing to purchase products, services and activities that are associated with achieving optimal wellness; and . a trend toward preventive health treatments. According to the 2000 Nutrition Business Journal Annual Industry Survey, global nutrition sales by region for 2000 and expected growth for the industry by region for 2001 and 2002 are as follows: Nutritional Expected Growth Sales for 2000 Percentage for Region (in billions) 2001/2002 ------ -------------- --------------- United States............................. $ 47.9 8% Canada.................................... 4.0 8% Australia................................. 1.7 7% Europe.................................... 45.7 6% Japan..................................... 24.4 6% Other regions............................. 14.2 7% ------ Total for all regions..................... $137.9 7% ====== 3

Mannatech believes nutritional supplements are most successful when they are sold primarily through: . direct sales organizations; . mass market retailers, including mass merchandisers, drug stores, supermarkets and discount stores; . health food stores; and . mail order companies. Operating Strengths Mannatech maintains the following business strategy: . to develop, maintain and continuously improve its proprietary nutritional supplements, which contain ingredients that are naturally- occurring, plant-derived and carbohydrate-based. New and existing products should have both health benefits and mass appeal to a general population, that is seeking non-toxic healthcare alternatives; . to provide an appealing framework for persons interested in its products to establish a network marketing business; and . to broaden its product focus in the nutritional supplement industry from the sickness sub-industry to also include the wellness sub-industry. Mannatech believes its business strategy will enable it to continue, by capitalizing on the following strengths: Proprietary Products. Mannatech believes that the discovery and development of products containing certain carbohydrates necessary for optimal health is key in expanding business opportunities for its associates. Mannatech recognized the nutritional need for the eight known monosaccharides in supporting optimal health and believes it offers innovative proprietary products to fulfill this nutritional need. Mannatech filed a patent application on its compound containing certain specific monosaccharides called Ambrotose(R) complex. Mannatech believes inclusion of this compound in its proprietary products is important for two reasons: . it is a marketing factor that continues to differentiate its products from its competitors; and . the limited availability helps drive demand and enable optimal pricing. Research and Development. Mannatech believes that its research and development facilities and experienced personnel will allow it to develop and market additional proprietary products. Mannatech's research and development efforts are led by scientists with significant years of experience designing products based on carbohydrate technology. Mannatech's technologically advanced laboratory is equipped with gas and liquid chromatographs and mass spectrometers, which are used to: . maintain quality standards; . support research and development in the area of new herbal complexes; and . help support the development of both new and existing products. To complement its in-house staff and facilities, Mannatech sought, and will continue to seek, strategic alliances with several large manufacturers of nutritional supplements. These companies work with Mannatech to create, develop and manufacture its proprietary products. Mannatech also works with other smaller companies to identify and develop new innovative products that complement its existing products. Associate Support Philosophy. Mannatech is committed to providing the highest level of support services to its associates and believes that it meets the needs of, and builds loyalty with, its associates through its highly personalized and responsive customer service. Mannatech sponsors four to six associate events throughout 4

the year to provide education and motivation for thousands of associates. These events offer information, aid in business development, provide a venue for launching new products and allow associates the ability to interact with Mannatech's leading distributors and researchers. Flexible Operating Strategy. Flexibility is a key part of Mannatech's ongoing operations. Mannatech currently outsources production and formed strategic alliances to minimize capital expenditures where practicable. Mannatech uses the expertise and resources of its strategic allies in the areas of distribution and logistics, call center operations, product registration and export requirements. Mannatech also continues to monitor its operating strategy to try to operate in an efficient and cost-effective manner. Experience and Depth of Mannatech's Management Team. Mannatech made significant management changes based on recent international expansion and lower than expected operating results. Within the last 12 months, Mannatech hired a new Chief Executive Officer, new Chief Information Officer and new President of International Operations. Mannatech also shifted certain management duties to its President and Chief Operating Officer. Finally, Mannatech hired its former President as a Global Vision Architect consultant, to concentrate his efforts and expertise on expansion, motivation and retention of Mannatech's associate base. Mannatech believes these management changes made during 2000 created a management group with a variety of backgrounds and expertise in various fields, including: . product research and development; . marketing; . direct sales and network marketing; . international operations; . finance and analysis; . legal and compliance; . information technology; and . product distribution. All of Mannatech's principal managers have substantial business experience, primarily with larger businesses. These managers are able to bring the perspective of traditional business to Mannatech's network marketing system. The primary goal of Mannatech 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 Mannatech's growth strategy is to: . Introduce New Products. Since its inception, Mannatech has and intends to continue to introduce new products each year. Mannatech expects each new product to contain one or more proprietary components and to complement existing products. . Attract and Retain New Associates and Enhance Associate Productivity. Mannatech focuses on its operating strengths and strives to create a business climate that recognizes associates for their achievements. Mannatech has introduced several new incentive programs for its associates, including a car bonus and "fast-start" programs. Further, Mannatech plans to simplify its incentive program for its associates, in part to encourage greater retention, motivation and productivity. In addition, Mannatech will continue to modify its associate events and recognition programs to encourage retention and growth in the number of associates. No single associate accounted for more than 10% of total sales, in 2000. 5

. Expand its Existing International Markets. Mannatech believes the potential for growth also exists in its international markets based upon its experience over the past year. Mannatech currently operates in Canada, Australia, the United Kingdom and Japan. In February 2001, Mannatech hired Mr. C. Armando Contreras to lead its international team of employees. Mr. Contreras brings to Mannatech considerable experience in network marketing as well as international market development. Mannatech suspended its plans to enter the New Zealand market in order to concentrate on growing its existing markets. Products and Product Development Mannatech believes it markets quality and proprietary products that include 26 different nutritional products and 3 topical products. Mannatech also offers a variety of sales aids, including enrollment and renewal packs, brochures, videotapes and a personalized website for its associates. Sales aids accounted for approximately 18.9%, 17.6% and 17.3% of net sales in 1998, 1999 and 2000, respectively. Mannatech scientists believe that the discovery and use of certain carbohydrates offer significant potential for nutritional benefits. Healthy bodies are comprised of many sophisticated components working together, which must have 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 carbohydrates is important because up to 85% of glycoproteins are composed of specific monosaccharides. Mannatech believes that these carbohydrates are necessary to support and maintain optimal health. Harper's Biochemistry, a leading biochemistry reference source, lists eight monosaccharides commonly found in human glycoproteins that are important to the healthy functioning of cell-to-cell communication, in the human body. These monosaccharides are as follows: . fucose; . galactose; . glucose; . mannose; . N-acetylgalactosamine; . N-acetylglucosamine; . N-acetylneuraminic acid; and . xylose. From the universe of approximately 200 monosaccharides found in nature, Mannatech's proprietary ingredient, Ambrotose(R) complex, is designed to provide certain of the monosaccharides listed above that are necessary for optimal cell-to-cell communication. Mannatech focuses on bringing new proprietary and, where possible, patentable, products to market when expanding its existing product line. Research and development costs related to specific clinical studies, quality assurance programs and new product development were approximately $391,000, $439,000 and $392,000 in 1998, 1999 and 2000, respectively. Mannatech 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 $3.4 million in 1998, $3.6 million in 1999 and $4.4 million in 2000. 6

All new products are expected to contain its proprietary components. Mannatech usually launches new products during its corporate events. New products selected for development are based on: . the marketability and proprietary nature of the product; . regulatory considerations; . the availability of ingredients; and . the existence of data supporting claims of functionality. To ensure quality control and to support, validate and monitor the proprietary nature of its products, Mannatech's quality assurance department conducts appropriate research both before and after product launches and continuously throughout the year by taking samples directly from shipments received from manufacturers. Product Distribution System Overview. The foundation of Mannatech's sales philosophy and distribution system is network marketing. Mannatech believes that its network-marketing system is an effective vehicle to distribute its products for the following reasons: . it is easier to explain the benefits of Mannatech's 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 the 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 . direct contact with customers help to facilitate repeat purchases. 8

Mannatech encourages, but does not require, associates to use its products, nor does it require a person to be an associate in order to purchase its products. Mannatech believes its network marketing system is particularly attractive to prospective associates for the following reasons: . the potential for income; . no requirement to purchase inventory; . no need to collect money from customers; . limited paperwork involved in the sales process; and . a flexible work schedule. Mannatech suggests associates enroll new associates with whom the associates have relationships such as: family members, friends, business associates, neighbors or otherwise. Mannatech believes that associates will be more likely to remain active if they are enrolled by someone with whom they have an ongoing relationship. Associates pay for products purchased prior to shipment. Mannatech carries no accounts receivable from its associates, except for amounts owed for check returns or other exceptions. Associates generally pay for products by credit card; however, orders are also paid with cash, money orders and checks. Associates may automatically order products on a continuous basis and receive a discount. Automatic orders accounted for approximately 44.9%, 47.1% and 49.2% of net sales for the years ended December 31, 1998, 1999 and 2000, respectively. Advances in communications, including telecommunications, the Internet and the increasing use of videotape players, fax machines and personal computers have enhanced the effectiveness of network marketing as a distribution channel in the past decade. Mannatech offers high-quality video and audiotapes for use in product education, demonstrations and sponsoring activities. In March 2000, Mannatech substantially completed its science-based website, www.GlycoScience.com, which allows users to search for science-based information about various nutritional ingredients, some of which are found in Mannatech's products. Mannatech believes these sales aids play an important role in the success of its associate efforts and Mannatech is committed to using current and future technological advances to enhance the effectiveness of the network marketing efforts of its associates. Associate Development. Mannatech believes key contributing factors to its long-term growth and success will be the recruitment of new associates and the retention of existing associates. Mannatech is active in the development of its associates, which includes the areas of recruitment, support, motivation and compensation. Mannatech primarily relies 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 Mannatech at wholesale prices and can sponsor other associates in order to build a network of associates and product users. Mannatech also relies heavily on existing associates to train new associates. Mannatech's 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 Mannatech provides brochures, magazines and other sales materials, advanced training is especially designed to provide systematic and uniform training to associates about Mannatech and its products, compensation plan and methods of doing business. Mannatech continues to update its training courses to ensure that its associates receive the latest information on its products, sales aids, technology advances, and sales methods available. The needs of Mannatech's associates are a priority and Mannatech believes that the high level of support it provides for its associates' efforts is important to Mannatech's success. Mannatech provides a large number of support services tailored to the needs of its associates, including: . motivational meetings; . educational and informative conference calls; 9

. 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; . web-based conference calls; . a current database of each associates' downline information; . business development materials that Mannatech believes will help increase product sales and recruitment; and . an innovative website database, www.GlycoScience.com, designed to provide a user with the ability to search and provide science-based information about nutritional ingredients, some of which are included in Mannatech's products. Mannatech currently recognizes 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, ranging from 15% of commissionable sales at the regional director level to 9% of commissionable sales at the presidential level, excluding the generational bonus. An associate can achieve four levels within presidential status. The levels are bronze, silver, gold and platinum. In addition, associates are eligible for a "generation bonus," which is an additional achievement level specially designed to motivate sales and downline growth. In 2001, Mannatech intends to simplify its plan, yet expand its associate recognition programs as necessary to reward increased levels of performance and to further motivate its associates. Associate Compensation. Mannatech's plan combines the aspects of two widely used multilevel marketing compensation plan concepts. Mannatech's plan pays commissions based on a percentage of the associate's commissionable sales and the attainment of certain associate leadership levels. The elements of Mannatech's compensation plan are similar to other multi-level marketing compensation plans. In addition each associate may determine their own optimal resale price of products purchased from Mannatech. Mannatech's compensation plan attempts to compensate an associate both in the early stages of building their business and when the associate has developed their business, by rewarding the associate for breadth and depth in their downline organizations. Mannatech's compensation plan pays the following: . a bonus or commission to qualified associates, ranging from $20.00 to $180.00 based on downline growth and commissionable product sales; . $25.00 to an associate for each eligible associate they train if they have completed advanced training and obtained the all star level; . bonuses or commissions ranging from $10.00 to $200.00 based on products included in starter or renewal packs sold; 10

. a "fast-start" bonus, ranging from $100.00 to $500.00, for a new associate who obtains regional or national level within three months of initially signing up as an associate; . a "car incentive" bonus, ranging from $200.00 to $700.00, for an associate who achieves certain sales levels and who has increased their product sales by at least 10% from their previous year's sales volume; and . various other bonus programs including earning various promotional travel awards. Based upon the knowledge of industry-related network marketing compensation plans, Mannatech believes that its compensation plan is among the most financially rewarding plans offered in the industry. Mannatech's commissions as a percentage of net sales was 40.4%, 40.9% and 41.2% for 1998, 1999 and 2000, respectively. Mannatech does not employ the entire compensation plan described above outside of the United States and Canada. In the international sector, Mannatech uses similar plans with regard to commissionable product sales that are tailored to fit the laws and considerations governing compensation of associates in each country. Mannatech integrated its international compensation plan across all markets in which its products are, or will be sold, thereby allowing associates to receive commissions for global product sales. Mannatech refers to this as its "global seamless downline structure" and hopes it will help associates to build their global networks by expanding their downlines into international markets without having to establish new downlines or requalify for higher levels of commissions within each new country. Mannatech's international compensation plan is designed to pay approximately the same percentage compensation as in the United States and Canada. Management of Associates. Mannatech believes it takes an active role in the management of its associates. Mannatech believes any oversight process is complicated because the associates are independent contractors and not employees of Mannatech. Mannatech seeks to restrict the statements and conduct of associates regarding its business by contractually binding associates to abide by its associate policies and procedures. Each associate receives a copy of the policies and procedures that must be followed in order to maintain associate status with Mannatech. Associates are expressly forbidden from making any representation of the possible earnings of any associate, other than through statements by Mannatech indicating the range of actual earnings by all associates. Mannatech also monitors its associate websites for content on a continuing basis and introduced MannapagesTM, a standardized, personal, Internet website program established to assist Mannatech in monitoring associate websites on a regular basis, and help associates in their sales efforts. Mannatech has established a compliance program for addressing associates who do not comply with its policies and procedures. Mannatech has developed formal steps for proceeding if a complaint is filed against an associate. Mannatech's primary goal is to educate its associates to ensure they understand and follow all of Mannatech's policies and procedures. Mannatech's compliance and legal departments, in cooperation with other departments, regularly evaluate associate conduct and the need for new and revised policies. Mannatech believes its compliance program assists in the maintenance of associate ethics and help associates in their sales efforts. Product Return Policy. Mannatech's product return policy states that any retail customer may return the unused portion of any product to the selling associate and receive a full cash refund from the associate. Mannatech will then reimburse any associate who provides a refund to a retail customer with product if they provide Mannatech with the proper documentation and return the remainder of the product to Mannatech. Mannatech's product return policy for associates states that any associate will receive a 90% refund 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 and returns as a percentage of net sales were 1.7%, 1.0% and 0.8% in 1998, 1999 and 2000, respectively. 11

Information Technology and Systems Mannatech believes that maintaining sophisticated and reliable transactions- processing systems is essential to its long-term success. Mannatech's systems are designed to: . reduce the time required to supply an associate or customer with products; . provide detailed and customized ordering information; . 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 the customer service department; and . help to monitor, analyze and report financial and operating results. During 2001, Mannatech expects to spend approximately $6.6 million on its information technology operations of which approximately $1.7 million will be for capital expenditures. These expenditures will help to provide new technology to continue to address the needs of associates and expand transaction-processing systems to accommodate international operations. Mannatech believes the significant investment in software, hardware and personnel will enable it to: . respond rapidly to its business needs for information technology assessment and development; . manage international operations and its seamless downline structure; . help identify areas in which Mannatech can reduce operating expenses; and . safeguard Mannatech's database. Mannatech's sophisticated financial system includes a report-writing system that is windows-based and capable of operating on several platforms. The financial system enables Mannatech to track and analyze financial information and create and produce customized reports. Mannatech believes its systems are adequate for its immediate future needs. Production and Distribution All of Mannatech's products are manufactured by outside contractors. This strategy provides Mannatech with the virtual production capacity necessary to respond to fluctuations in its sales, but limiting its investment in capital equipment. Mannatech believes that it currently has the contract manufacturers' support necessary to meet inventory requirements over the next several years. Mannatech continues to identify new quality-driven manufacturers to supply the products necessary for its success. Mannatech also continues to seek cost- cutting measures by periodically reviewing current pricing considerations and by requiring competitive bids from various manufacturers that meet its quality and performance requirements. Mannatech currently acquires its ingredients from superior suppliers of such ingredients and has identified dependable alternative sources for all of its ingredients except Manapol(R) and Arabinogalactan, which are components of Ambrotose(R) complex. With these alternative sources, Mannatech could produce, purchase or replace any of the ingredients if it was unable to purchase any of these ingredients from its current suppliers. In January 2000, Mannatech signed a new supply agreement with its supplier of Manapol(R) and in February 2001, modified the purchasing requirements of the supply agreement. The supply agreement requires Mannatech to buy a minimum monthly volume at an agreed-upon price through August 2002. Mannatech's distribution operation is located in Coppell, Texas, and consists of 75,000 square feet of leased space in which it maintains its automated system capable of processing up to 18,000 orders per day. This system enhances productivity and will support sales volume growth. The distribution facility contains 12

warehouse and distribution offices. Mannatech also has contract distribution facilities in Canada, Australia, the United Kingdom and Japan. For further information on these contract facilities see "Properties" on page 18 of this report. Government Regulations In the United States, network marketing activities are regulated by a large number of laws, governmental regulations, administrative determinations, court decisions and similar legal requirements at the federal, state and local levels. These regulations address, among other things: . network marketing systems; . transfer pricing and similar regulations affecting the amount of foreign taxes and customs duties paid; . taxation of associates, and the requirement to collect taxes and maintain appropriate records; . how a company makes, packages, labels, distributes, imports, sells and stores products; . product ingredients; . product claims; . advertising; and . the extent in which a company may be responsible for associates' claims about its products. Products. The following governmental agencies regulate some aspect of Mannatech's business or its products in the United States: . 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 and localities, in which Mannatech's products are sold. The Food and Drug Administration regulates the formulation, manufacture, packaging, storage, labeling, promotion, distribution and sale of foods, dietary supplements and over-the-counter drugs. Food and Drug Administration regulations require both Mannatech and its suppliers to meet good manufacturing practice regulations for the preparation, packing and storage of its products and has published a Notice of Advanced Rule Making for good manufacturing practices for dietary supplements. On January 6, 2000, the Food and Drug Administration issued a final rule called "Statements made for Dietary Supplements Concerning the Effect of the Product on the Structure or Function of the Body." Mannatech believes this final rule has not had an adverse effect as it was already in compliance. 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. Mannatech believes this act is generally favorable to the dietary supplement industry because it created a new class, by statute, of "dietary supplements," which includes vitamins, minerals, herbs, amino acids and other dietary substances for human use to supplement the diet. This act grandfathers, with certain limitations, dietary ingredients on the market before October 15, 1994. A dietary supplement that contains a dietary ingredient that was not on the market before October 15, 1994 must provide evidence establishing that the supplement is reasonably expected 13

to be safe. Manufacturers of dietary supplements that 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 Mannatech markets are classified as dietary supplements under the Federal Food, Drug and Cosmetic Act. In 1999, the Food and Drug Administration issued new regulations governing the labeling and marketing of dietary supplement products. These regulations include: . 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. Mannatech is required to continue its ongoing program of providing evidence for its product performance claims, and to notify the Food and Drug Administration of certain types of performance claims made for its products. Mannatech's substantiation program involves compiling and reviewing the scientific literature pertinent to the ingredients contained in its products. In certain markets, including the United States, claims made by Mannatech with respect to dietary supplements, personal care or any of its other products may change the regulatory status of the product. For example, in the United States, the Food and Drug Administration could possibly take the position that claims made for some of Mannatech's 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 Mannatech sells that is labeled as an over-the-counter monograph drug. If the Food and Drug Administration asserts that the product claims cause it to be considered new drugs or fall within the scope of over-the-counter monographs, Mannatech would be required to file a new drug application and comply with the applicable monographs or change the claims made in connection with such products. Dietary supplements are also 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 research and is pre-approved by the Food and Drug Administration. The Federal Trade Commission regulates the marketing practices and advertising of all of Mannatech's 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 also increased its review of the use of the type of testimonials Mannatech uses in its 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 14

threatened an enforcement action against Mannatech for the advertising of its products, there can be no assurance that the Federal Trade Commission will not question Mannatech's advertising or other operations in the future. Mannatech cannot predict the contents of any future laws, regulations, interpretations or applications or the future impact of different governmental regulations; however, any or all of such requirements maybe costly to Mannatech. Future regulations could require Mannatech to: . change in the way it conducts business; . change its product contents; . keep additional records; . increase the available documentation of its product properties; and/or . increase or use different labeling and scientific proof of product ingredients, safety or usefulness. Network Marketing System. Mannatech's network marketing system, which includes Mannatech's compensation plan, is controlled by a number of federal and state statutes and regulations, and is administered by the Federal Trade Commission, various state authorities and foreign government agencies. The legal requirements controlling network marketing organizations are, in part, directed to ensure 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 states or provinces limit the amount associates may earn from commissions on sales by other associates, not directly sponsored by the associate. Mannatech believes it has and will continue to obtain regulatory approval of its network marketing system in jurisdictions that require such approval. If regulatory approval is not required, Mannatech relies on the advice of counsel to ensure regulatory compliance. As a result of contents contained in an associate's self-generated literature, the Michigan Attorney General's office contacted Mannatech in the summer of 1999 and asked Mannatech to provide data maintained under a consent decree. In addition, the Attorney General requested documentation of the measures taken to address the associate's conduct, the measures implemented in order to prevent a violation of the decree from occurring and the measures that would be implemented in the future to help ensure compliance with the consent decree. Mannatech cooperated and believes it complied with this request. In order to comply with the State of Michigan's Franchise Investment law against involuntary inventory stockpiling, Mannatech monitors its associates in the state of Michigan by conducting random audits of its associates in Michigan to identify evidence of stockpiling and coerced sales. To date, Mannatech has found no evidence of coerced sales or stockpiling by its associates in Michigan. Mannatech designed its associates' policies and procedures to provide no incentive or reward to an associate for engaging in such activities. In Canada, Mannatech's network marketing system is regulated by both national and provincial law. Under Canada's Federal Competition Act, Mannatech must make sure that any representations relating to associate compensation made to prospective associates constitute fair, reasonable and timely disclosure and that it meets other legal requirements of the Federal Competition Act. Mannatech's compensation plan has been reviewed and no objection to its provisions was received from the appropriate Canadian authorities. All Canadian provinces and territories other than Ontario have legislation requiring that Mannatech register or become licensed 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 its associates be licensed. Mannatech believes it holds all of the required provincial or territorial direct sellers' licenses. In Australia, Mannatech's network marketing system is subject to both federal and state regulation. The compensation plan in Australia is designed to meet state requirements and the requirements of Australia's Trade Practices Act. Mannatech's business and trade practices and those of its associates, are regulated by state law and the Trade Practices Act. Claims and representations relating to its products are regulated by both the Trade Practices Act and Australia's Therapeutic Goods Act. 15

In the United Kingdom, Mannatech's network marketing system is subject to national regulations. The 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 of 1997. Mannatech's business and trade practices, and those of 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 Mannatech's business are regulated by the Trading Standards Office. In Japan, Mannatech's network marketing system, business and trade practices, compensation plan and associates are governed by the Door-to-Door Sales law as enacted in 1976 by the Department of Trade and Ministry. Other Regulations. Mannatech is 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; . consumption taxes; . customs duties; . employee/independent contractor regulations; . employment and severance pay requirements; . import/export regulations; and . antitrust laws. For example, in many markets Mannatech is restricted in the amounts and types of rules and termination criteria that it can contractually impose on its associates. If Mannatech does not comply with these restrictions, it may be required to pay social security or other tax or tax-type assessments on behalf of its associates, and may incur severance obligations to terminate the associate. In some foreign countries, Mannatech may also be subject to such taxes or payment requirements. In some countries, including the United States, Mannatech is also governed by regulations concerning the activities of its associates. Regulators may find that Mannatech is responsible for its associates' conduct and may request or require that Mannatech take steps to make certain that its associates comply with these regulations. The types of conduct governed by regulations include, in part: . claims made about products; . promises or claims of income by Mannatech or its associates; and . sales of products in markets where the products have not been approved, licensed or legally allowed for sale. In some markets, including the United States, improper product claims by its associates could cause Mannatech's products to be reviewed or re-reviewed by regulatory authorities. This review could result in Mannatech's 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 its business, Mannatech has developed formal compliance measures that include associate disciplinary procedures and internal policies for compliance with the Food and Drug Administration and Federal Trade Commission rules and regulations. 16

Mannatech continues to research laws governing associate conduct and to revise or alter its business system, compensation plans, associate requirements and other materials and programs as required by laws and regulations in each market. Mannatech attempts to educate its associates about acceptable business conduct in each market through policies, procedures, manuals, seminars and other training materials and programs. Mannatech is able to perform only limited monitoring procedures to make certain that associates comply with existing policies, procedures and regulations, Mannatech cannot promise that all of its associates comply with all existing policies, procedures and regulations. Competition The nutritional supplements industry is large and intensely competitive. Mannatech competes directly with companies that manufacture and market nutritional products with similar product lines, including: . Solgar Vitamin and Herb Company, Inc.; . Nu Skin Enterprises, Inc.; . Twinlab Corporation; . Usana, Inc.; . Natures Sunshine Products, Inc.; and . Weider Nutrition International, Inc. Nutritional supplements are offered for sale in a variety of ways. While Mannatech believes that consumers appreciate the convenience of ordering products from home through a sales person or the Internet, the buying habits of many consumers who purchased products through traditional retail methods are difficult to change. The number of Mannatech's products in each product category is also relatively small compared to the wide variety of products offered by many other nutritional product companies. Mannatech also competes for new associates with other retail, multilevel marketing and direct selling companies in the nutritional supplements industry. Many of its 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.; . Mary Kay Cosmetics, Inc.; . Forever Living Products, Inc.; and . Melaleuca, Inc. Mannatech believes it competes for new associates by stressing the ease of its delivery system, the superiority of its compensation plans and its proprietary and quality products. Because the pool of individuals interested in direct selling is limited in each market, available recruits are reduced when other network marketing companies successfully recruit these people into their businesses. Employees As of December 31, 2000, Mannatech employed 263 people in the United States, of which 10 people occupy executive postions. Mannatech also employs 14 people in Australia 12 people in the United Kingdom and 15 people in Japan. This number does not include Mannatech's associates, who are independent contractors and not employees of Mannatech. Mannatech employees are not unionized and Mannatech believes it has a good relationship with its employees. 17

Legal Proceedings In October 1997, Mannatech filed a Notice of Objection to the issuance of a registered trademark being issued to IntraCell Nutrition, Inc., which had filed a trademark application for the name, "Manna." On May 19, 2000, Mannatech's Notice of Opposition to the issuance of a registered trademark issued to IntraCell Nutrition, Inc. for the name "Manna" was rejected. To date, no action has been filed against Mannatech by IntraCell, which would contend any infringement by Mannatech on that of IntraCell. If IntraCell brings any infringement action against Mannatech, an adverse determination could have an adverse effect on Mannatech's business, results of operations, financial condition and liquidity. On August 20, 1999, Mannatech filed a lawsuit against Dr. Daryl See in the United States District Court for the Northern District of Texas 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 its products had been funded by the National Institutes of Health and conducted under the auspices of the University of California-Irvine. On May 22, 2000, Mannatech agreed to dismiss all claims against Dr. Daryl See. Under the terms of the settlement agreement, Dr. See's conduct was restricted regarding Mannatech, its products and associates. On February 24, 2000, Ms. Caroline Rivers filed a class action complaint against Mannatech and three other defendants, in the District Court, County of Boulder, State of Colorado alleging breach of contract, negligence and that the defendants were marketing and selling illegal health insurance policies. On June 29, 2000, Mannatech's Motion for Dismissal was granted and all claims relating to the uncertified class action complaint were dismissed against Mannatech. 18

On May 30, 2000, Mannatech filed suit for breach of contract in the United States District Court of the Northern District of Texas, Dallas Division, against Gryphon Advisors II, L.L.C., a Delaware limited liability company. Mannatech alleged amounts billed for out-of-pocket expenses and advisory service fees totaling $1.6 million were unreasonable and that Gryphon Advisors breached the advisory agreement. Under the Advisory agreement, Gryphon was to provide advice on potential financing opportunities, acquisitions, the financial management of Mannatech, all aspects of its capital structure, capital-raising transactions and assist Mannatech in evaluating potential acquisition targets. On June 26, 2000, Gryphon Advisors filed a cross-action suit for breach of contract and fraud seeking the payment of $1.6 million and exemplary damages. On March 1, 2001, Mannatech and Gryphon Advisors agreed to dismiss its respective claims with prejudice and Mannatech agreed to pay Gryphon Advisors $650,000 over a 12-month period. Item 4. Submission of Matters to a Vote of Security Holders None. PART II Item 5. Market for Registrant's Common Equity and Related Shareholder Matters Market for its Common Stock. On February 12, 1999, Mannatech completed its initial public offering and on February 16, 1999, its common stock began trading on the Nasdaq National Market under the symbol "MTEX." As of March 19, 2001 the total number of outstanding shares of its common stock was 24,799,301 and the closing price on such date was $1.156. Pricing information prior to February 16, 1999 is not available, because Mannatech's common stock was not publicly traded prior to that date. Set forth below are the high and low sales prices of Mannatech's common stock as reported on the Nasdaq National Market for each quarter of the fiscal years ended December 31, 1999 and 2000: High Low ------- ------- First Quarter (from February 16, 1999)......................... $31.750 $10.500 Second Quarter 1999............................................ $23.875 $10.125 Third Quarter 1999............................................. $13.625 $ 6.563 Fourth Quarter 1999............................................ $ 8.875 $ 4.625 First Quarter 2000............................................. $ 5.313 $ 3.688 Second Quarter 2000............................................ $ 3.938 $ 2.125 Third Quarter 2000............................................. $ 3.875 $ 1.125 Fourth Quarter 2000............................................ $ 2.469 $ 1.234 Holders.

(4) Dividends were calculated based upon shares outstanding prior to the stock split and Mannatech's reorganization (10,000 shares), each of which took place in 1997. Aggregate dividends declared amounted to $100,000 in 1996. Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations The following discussion is intended to assist in the understanding of Mannatech's financial position and results of its operations for the three years ended December 31, 2000. This discussion should be read in conjunction with the Consolidated Financial Statements and related Notes in Item 14, beginning on page F-1. Unless stated otherwise, all financial information presented below, throughout this report and in the Consolidated Financial Statements and related Notes includes Mannatech and all of its subsidiaries on a consolidated basis. Overview Mannatech develops and sells proprietary nutritional supplements and topical products in the United States, Canada, Australia, the United Kingdom and Japan, through a worldwide network marketing system of approximately 237,000 active associates as of March 8, 2001, compared to approximately 269,000 active associates as of March 9, 2000. Mannatech's diluted earnings (loss) per share was ($0.30) for the year ended December 31, 2000 compared to $0.43 per share in 1999. This decrease was primarily due to the following: . a decrease in sales of $29.7 million; . incurring approximately $4.1 million in expenses related to its Internet website subsidiary, Internet Health Group, Inc., which includes: funding its operating losses, recording a write-off of its fixed asset software of $870,000, a write-off of its inventory of $837,000 and the cancellation of various agreements relating to closing its operations as of December 29, 2000 totaled approximately $332,000; . incurring $4.2 million for start-up expenses relating to the expansion into Japan; and . accruing $1.0 million for various severance packages related to the former Chief Operating Officer of International Operations and former Chief Information Officer. In 2001, Mannatech increased some of the sale prices of its products, starter and renewal packs and shipping fees; however, it believes the negative trend in sales will continue into the first half of 2001. In the future, Mannatech expects its international operations to account for an increasing percentage of consolidated net sales. The net sales by country as a percentage of consolidated net sales were as follows: Year Ended December 31, U.S. Canada Australia U.K. Japan Total ----------------------- ----- ------ --------- ---- ----- ------ 2000.............................. 77.0% 13.5% 5.7% 1.3% 2.5% 100.0% 1999.............................. 76.7% 14.3% 8.8% 0.2% 0.0% 100.0% 1998.............................. 82.5% 16.1% 1.4% 0.0% 0.0% 100.0% Net sales for the United States, Canada and Australia continue to decrease as compared to the same period in 1999. Mannatech believes the decrease is due to a number of factors including the following: . its associates in the United States, Canada and Australia concentrating their efforts on the development of Mannatech's presence in the United Kingdom and Japan; . some of its associates exploring new competitive Internet networking companies as another way to supplement their income; . associates' concerns about recent management changes; and 21

. concerns about the decline of Mannatech's stock price which may, in part may have resulted from unanticipated selling pressure. On October 28, 2000, Mannatech introduced a new product, ImmunoStart(TM) Chewables, which helps trigger immune responses. In March 2001, Mannatech introduced a chewable multi-vitamin for children called Glyco-Bears(TM). Mannatech also intends to introduce other new products during 2001, which it hopes will further complement its current products and help boost net sales. Mannatech's revenues are primarily derived from sales of its products and associate starter and renewal packs, which include some combination of its 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 received a $50 credit toward admission to one of Mannatech's corporate events. In January 2001, Mannatech made changes to some of its packs including a change in product mix, price changes and the discontinuation of the credit toward admission. Mannatech tries to offer a comparable associate starter pack in each country in which it does business; however, each country has different regulatory guidelines that must be followed and therefore not all of Mannatech's packs are offered in all countries. Mannatech adopted Staff Accounting Bulletin No. 101 "Revenue Recognition in Financial Statements" ("SAB 101") in the fourth quarter of 2000. Under SAB 101, Mannatech is required to defer the recognition of revenues until the associate receives the products shipped. The adoption of SAB 101 resulted in a cumulative effect of accounting change of approximately $210,000, net of tax of $126,000. On average, the wholesale value of the nutritional and topical products contained in each of Mannatech's starter and renewal packs is between 60% and 70% of the total wholesale value of the packs and the remainder of the total wholesale value consists of various promotional materials and products. If the pack contains a credit toward admission to a corporate event, the revenue from the promotional pack is allocated between product revenue and the corporate event admission based on the proportionate fair value of these items. Mannatech defers revenue received from the sale of its promotional packs to the extent that the sales price is greater than the wholesale value of the individual items included in such packs. Allocated corporate event admission revenues are also deferred. All deferred revenue is amortized over a twelve-month period. Total deferred revenue was approximately $845,000 at December 31, 1999 and $691,000 at December 31, 2000. Mannatech compensates its 7 associates by commissions and incentives, which is its most significant expense; however, the commission structure is designed not to materially exceed 42% of commissionable net sales. Mannatech plans to announce some changes to its worldwide compensation plans, yet offer more bonuses and incentive programs and revamp the training program for its associates. The changes would simplify the compensation plan but would not change the total commission paid as a percentage of net sales. Commissions and incentives are paid to associates based on the following: . associates' placement and position within the compensation plan; . volume of their direct commissionable sales; 22

. number of new enrolled associates; and . achievement of certain levels to qualify for incentive programs. In 2000, Mannatech's United States federal statutory tax rate was 34%. Mannatech pays taxes in Australia at a statutory tax rate of approximately 36% and in the United Kingdom at a statutory tax rate of approximately 31%. Mannatech expects to pay taxes in Japan at a statutory tax rate ranging between 42% and 48%. Mannatech also pays taxes in various state jurisdictions at an approximate average effective tax rate of 3%. Due to its international operations, a portion of Mannatech's income will be subject to taxation in the countries in which it operates; however, it may receive foreign tax credits that would reduce the amount of United States taxes owed. Mannatech may not be able to use all of such foreign tax credits in the United States. Mannatech may also incur net operating losses that may not be fully realizable. Results of Operations The following table summarizes Mannatech's consolidated operating results as a percentage of net sales for each of the years indicated: Year Ended December 31, ------------------------- 1998 1999 2000 ------- ------- ------- Net sales......................................... 100.0% 100.0% 100.0% Cost of sales..................................... 16.5 16.2 18.0 Commissions....................................... 40.4 40.9 41.2 ------- ------- ------- Gross profit.................................... 43.1 42.9 40.8 Operating expenses: Selling and administrative expenses............. 19.3 19.4 24.7 Other operating costs........................... 13.6 14.5 21.1 Write-off of fixed asset........................ -- -- 0.6 Write-off of deferred offering costs............ 0.5 -- -- ------- ------- ------- Income (loss) from operations..................... 9.7 9.0 (5.6) Interest income...................................

Net sales decreased (16.5%) to $150.0 million in 2000 from $179.7 million in 1999. This decrease was primarily composed of the following: . a $5.0 million increase from the sale of new products introduced during 2000, including the Optimal Health Pack(TM) and ImmunoStart(TM) Chewables; 23

. a ($29.8) million decrease in existing product sales resulting from a decrease in the volume of products sold, and . a decrease of ($4.9) million from associate pack sales. Of this ($4.9) million decrease, approximately ($4.2) million resulted from an overall decrease in the number of associate packs sold to new associates. The additional decrease of approximately ($700,000) resulted from a decrease in the number of associate renewal packs sold. Mannatech is exploring ways and strategies to increase associate pack and renewal pack sales. Cost of Sales. Cost of sales decreased (6.9%) to $27.1 million in 2000 from $29.1 million in 1999. As a percentage of net sales, cost of sales increased to 18.0% in 2000 from 16.2% in 1999. The increase in cost of sales as a percentage of net sales was primarily due to the inventory write-off of Internet Health Group, Inc. and a change in the product mix of finished goods sold. The dollar decrease was primarily due to: . the write-off of approximately $837,000 for the inventory of Internet Health Group, Inc.; . a write-off of approximately $300,000 for obsolete sales aids; and . a decrease in volume of finished goods sold. Commissions. Commissions consist of payments to associates for sales activity and downline growth. Commissions decreased (16.2%) to $61.7 million in 2000 from $73.6 million in 1999. As a percentage of net sales, commissions increased to 41.2% in 2000 from 40.9% in 1999. The increase as a percentage of sales was the result of the introduction of new incentive programs during 2000. The dollar decrease was the direct result of a decrease in the number of associate packs sold, which was partially offset by the introduction of new incentive programs for associates, which includes the car bonus and "fast- start" programs. Gross Profit. Gross profit decreased (20.5%) to $61.2 million in 2000 from $77.0 million in 1999. As a percentage of net sales, gross profit decreased to 40.8% in 2000 from 42.9% in 1999. These changes were primarily attributable to the factors described above. Selling and Administrative Expenses. Selling and administrative expenses include wages, bonuses, shipping and freight and marketing expenses and are a mixture of both fixed and variable expenses. Selling and administrative expenses increased 6.0% to $37.0 million in 2000 from $34.9 million in 1999. As a percentage of net sales, selling and administrative expenses increased to 24.7% in 2000 from 19.4% in 1999 due to a decrease in net sales, which did not reduce the fixed and semi-variable expenses. The dollar increase was due primarily to the following: . a $1.4 million increase in wages and contract labor, primarily from various pay raises, an increase in personnel for the United Kingdom and Japan and hiring a new Chief Executive Officer and a new Chief Information Officer; . a $1.0 million charge for severance packages related to the former Chief Information Officer and former Chief Operating Officer of International Operations; . a decrease in freight cost of ($1.0) million; . a $1.7 million increase in expenses related to hosting various events related to international expansion; and . a decrease in management bonuses of ($1.0) million. Other Operating Costs. Other operating costs include utilities, depreciation, travel, office supplies and printing expenses. Other operating costs increased 21.5% to $31.7 million in 2000 from $26.1 million in 1999. As a percentage of net sales, other operating costs increased to 21.1% in 2000 from 14.5% in 1999. The dollar increase was primarily due to the following: . a $4.6 million increase for travel, accounting, building rent and consulting services related to the international expansion; 24

. recording $600,000 for the settlement of the Gryphon Advisors L.L.C. lawsuit; and . paying Mr. Samuel L. Caster, the former President, $350,000 for consulting services, as described in the Notes to the Consolidated Financial Statements, in Item 14, of this report, beginning on page F-1. Write-off of Fixed Asset. In the second quarter of 2000, Mannatech recorded an impairment charge of $870,000 as it determined the fixed asset software of Internet Health Group. Inc., provided no future benefit. On December 29, 2000, Internet Health Group, Inc. ceased operations. Interest Income. Interest income decreased (4.1%) to $684,000 in 2000 from $713,000 in 1999. As a percentage of net sales, interest income increased to 0.5% in 2000 from 0.4% in 1999. The dollar decrease was primarily due to using investments to fund Mannatech's current year operations, including its international expansion. Interest Expense. Interest expense decreased (54.0%) to $69,000 in 2000 from $150,000 in 1999. As a percentage of net sales, interest expense remained the same at 0.1% in 2000 and in 1999. The dollar decrease was primarily due to the repayment of the existing loan and leases during the year. Other Expense, Net. Other expense may consist of penalties related to tax payments for payroll, income and sales, foreign currency translation adjustments and miscellaneous non-operating items. Other expense increased 389.5% to $558,000 in 2000 from $114,000 in 1999. As a percentage of net sales, other expense increased to 0.4% in 2000 from 0.1% in 1999. For the year ended December 31, 2000, other expense consisted primarily of translation exchange losses of $359,000 and $36,000 in sales tax payments and tax penalties. In 1999, other expense consisted primarily of federal tax penalties. Income Tax Expense (Benefit). Income tax expense (benefit) decreased to ($1.2) million in 2000 from $5.7 million in 1999. Mannatech's effective tax rate decreased to 14.8% in 2000 from 34.7% in 1999. Mannatech's effective tax rate decreased primarily as a result of the establishment of a valuation allowance for the net operating losses from its Japan subsidiary. Cumulative Effect of Accounting Change. In the fourth quarter of 2000, Mannatech adopted Staff Accounting Bulletin No. 101 "Revenue Recognition in Financial Statements" ("SAB 101") which resulted in a charge of $210,000, net of tax of $126,000 for the cumulative effect of the accounting change. SAB 101 requires Mannatech to defer the recognition of revenues until the associates receive products shipped by Mannatech. Net Income (loss). Net income (loss) decreased to ($7.3) million in 2000 from $10.8 million in 1999. As a percentage of net sales, net income decreased to (4.9%) in 2000 from 6.0% in 1999. The decrease was due to net sales decreasing by 16.5%, expenses incurred related to its international expansion, recording various severance packages and discontinuing operations of Internet Health Group, Inc. 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; . 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 year 1999; and . 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 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 the international expansion and hiring a marketing firm to concentrate on the associate renewal program. 25

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 sales as a percentage of net sales was primarily due to changes in the product mix of finished goods sold. The dollar increase was primarily due to: . an increase in volume of finished goods sold; . the recording of $160,000 for recovery of inventory in 1998 which had been written off in 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 of operations in Australia in October 1998; and . the start 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 include wages, bonuses, shipping and freight 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 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 increase was primarily due to the following: . a $750,000 charge for the cancellation of the remaining incentive contract with Mr. 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 the international expansion; . $350,000 for settlement of various lawsuits; . $225,000 incurred related to the secondary offering for certain existing shareholders; and . $200,000 for additional research and development costs related to opening Mannatech's laboratory facility. Write-off of Deferred Offering Costs. During August 1998, Mannatech withdrew its original underwritten institutional/retail offering and recorded a one-time charge of approximately $847,000. Interest Income. Interest income increased 675.0% 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 was invested in interest bearing accounts and certain investments. 26

Interest Expense. Interest expense increased 183.0% 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 of two lease agreements with a bank to purchase various equipment for the warehouse and laboratory facility. Other Expense, Net. Other expense consists of penalties related to tax payments for payroll, income and sales and miscellaneous non-operating 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. In 1999, other expense consisted primarily of federal tax penalties. In 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, Mannatech's effective tax rate decreased to 34.7% in 1999 from 36.4% in 1998. The 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 which averaged 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%, which was partially offset by expenses incurred related to the international expansion and cancellation of the remaining incentive compensation contract for $750,000. Seasonality and Selected Quarterly Statements of Operations Mannatech believes the impact of seasonality on its results of operations is minimal. Mannatech has and may continue to experience variations on its quarterly results of operations in response to, among other things: . 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 its products and overall operations. As a result of these and other factors, the quarterly results may vary significantly in the future. Period-to-period comparisons should not be relied upon as an indication of future performance since Mannatech can give no assurances that the revenue growth rate in new markets will follow its historical pattern. The market price of Mannatech's common stock may also be adversely affected by the above factors. 27

The following table sets forth the unaudited consolidated quarterly statement of income data for the periods indicated. In Mannatech's opinion, this information has been prepared on the same basis as its audited Consolidated Financial Statements set forth in this report and includes all necessary adjustments, consisting only of normal recurring adjustments, that are considered necessary to present fairly this information in accordance with generally accepted accounting principles. You should read this information in conjunction with the Consolidated Financial Statements and related Notes in Item 14 of this report, beginning on page F-1. Mannatech's consolidated operating results for any one quarter are not necessarily indicative of results for any future period.

(8) Computed on the basis described in Note 1 in the Notes to the Consolidated Financial Statements. Liquidity and Capital Resources In February 1999, Mannatech received approximately $9.2 million in net proceeds from the sale of its common stock in its initial public offering. In the initial public offering, certain existing shareholders sold 1,556,016 shares and Mannatech sold 1,500,000 shares of its common stock, at $8.00 per share. Mannatech used approximately $6.3 million of the proceeds from the initial public offering for international expansion, including product registration, initial inventory requirements and similar items. The remaining $2.9 million was used to fund working capital and for general corporate purposes. During 1999, Mannatech also received $641,271 from the exercise of 475,015 outstanding warrants at $1.35 per share and received $785,600 from the exercise of 563,774 stock options at a prices per share ranging from $1.35 to $2.00. During 2000, Mannatech received $363,000 from the exercise of 260,700 stock options at prices per share ranging from $1.35 to $2.00. Mannatech's primary capital requirement is to fund working capital that historically been financed through operations. As a result of expenditures on its facilities, equipment and personnel to support its international expansion, Mannatech's working capital decreased from $11.7 million at December 31, 1999 to $7.3 million at December 31, 2000. In 1999, Mannatech invested approximately $600,000 in the expansion into the United Kingdom. Mannatech paid approximately $1.3 million in dividends to its shareholders in 1999. In 2000, Mannatech invested approximately $4.4 million in its expansion into Japan and $4.1 million to fund operations for Internet Health Group, Inc. Mannatech plans to fund its 2001 working capital through its operations. In March and August 1998, Mannatech 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 leased assets, are payable in 36 monthly installments and contain various financial covenants. At December 31, 2000, Mannatech violated the annual cash flow coverage ratio covenant but obtained a waiver from the bank on March 14, 2001 that waived this violation at December 31, 2000. In July 1998, Mannatech entered into a 36-month, unsecured note payable with a finance company to finance a 3-year product liability insurance premium. The initial principal amount of this note was $435,670, with interest at 8.0% and due in monthly installments through December 2000. Net cash provided by (used in) operating activities was $18.1 million, $4.8 million and ($4.6) million in 1998, 1999 and 2000, respectively. In 1998, operating activities included net income and increases in accrued operating expenses and inventory. In 1999, operating activities consisted of net income, an increase in inventory, a decrease in accured operating expenses and recording the tax benefit related to the exercise of warrants and options. In 2000, operating activities included a net loss and increases in income tax receivable and accrued operating expenses. The increase in accrued operating expenses was the result of recording severance packages and closing operations of Internet Health Group, Inc. Net cash (used in) investing activities was ($4.4) million, ($4.6) million and ($1.7) million in 1998, 1999 and 2000, respectively. In 1998, these activities consisted of the relocation of the Texas distribution center, the 29

build-out of the research and development facility and the development and implementation of its proprietary software. In 1999, these activities consisted primarily of purchases of computer hardware, continued internal development of Mannatech's propriety software, furnishings for the Australian and United Kingdom operations and interest from investments of the net proceeds from its initial public offering, which were partially offset by the repayment of notes receivable due from certain shareholders of approximately $944,000. In 2000, these activities consisted of approximately $4.1 million for purchases of fixed assets primarily for the Japan operations, offset by the maturities of investments of $2.3 million and the repayment of the notes receivable due from certain shareholders of approximately $124,000. Mannatech believes its facilities and software programs should be sufficient for its immediate needs. Net cash provided by (used in) financing activities totaled ($12.9) million, $10.6 million and $0.6 million in 1998, 1999 and 2000, respectively. In 1998, Mannatech paid dividends on a monthly basis to its 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. During 1999, gross initial public offering proceeds of approximately $12.0 million were received and proceeds of $786,000 were received from the exercise of certain stock options, which were partially offset by the repayment of capital leases and a note payable of approximately $900,000. During 2000, proceeds of approximately $363,000 were received from the exercise of stock options, which was partially offset by the repayment of capital leases and a note payable of $730,000, issuance of a $500,000 loan and lock-up agreement to Mr. Charles E. Fioretti and recording cash overdrafts of approximately $1.5 million. Under the terms of the lock-up and repurchase agreement, Mannatech will be required for the next 12 months, beginning March 3, 2001 to purchase $83,333.33 worth of common stock from Mr. Charles Fioretti valued at 90% of the fair market price, in exchange, Mr. Charles Fioretti will be prohibited from trading his shares of Mannatech common stock through March 2, 2002, unless approved by the Board of Directors. Mannatech believes that its existing capital resources, including gross cash provided by operating activities, bank borrowings and suspension of dividend payments to shareholders, should be adequate to fund its operations for at least the next 12 months. Mannatech has no present commitments or agreements with respect to any acquisitions or purchases of manufacturing facilities or new technologies. Future changes could occur that would consume available capital resources faster than anticipated. Mannatech's capital requirements depend on numerous factors, including: . the introduction of new products; . changes in the number of associates and the retention rate of the associate base; and . research and development efforts. If existing capital resources are insufficient to meet Mannatech's capital requirements for 2001, Mannatech would be required to raise additional funds, which it cannot assure will be available on favorable terms, if at all. Impact of Inflation Mannatech believes that inflation historically has not had a material impact on its operations or profitability. Mannatech expanded into Australia in 1998, into the United Kingdom in 1999 and into Japan in 2000. Revenues and expenses in foreign markets are currently translated using historical and weighted-average currency exchange rates; therefore a weakening United States dollar would have a positive impact whereas a strengthening United States dollar would have a negative impact on translations of its foreign operations. Recent Financial Accounting Standards Board Statements 30

In June 1998, the Financial Accounting Standards Board issued Financial Accounting Standard No. 133, "Accounting for Derivative, Instruments and Hedging Activities" ("FAS 133"). This statement establishes accounting and reporting standards for hedging activites and derivative financial instruments, including certain derivative financial instruments embedded in other contracts. In June 1999, the Financial Accounting Standards Board issued Financial Accounting Standard No. 137, which defers the effective date of FAS No. 133 to fiscal years beginning after June 15, 2000. In June 2000, the Financial Accounting Standards Board issued Financial Accounting Standard No. 138, "Accounting for Certain Derivative Instruments and Certain Hedging Activities," which addressed certain issues causing implementation difficulties. Mannatech has adopted FAS 133 and the corresponding amendments on January 1, 2001. The adoption of this statement is not expected to have a material impact on Mannatech's consolidated financial position, results of operation or cash flows. Item 7A. Quantitative and Qualitative Disclosures about Market Risk Mannatech does not engage in trading market-risk-sensitive instruments and does not purchase as investments, as hedges, or for purposes "other than trading," instruments that are likely to expose it to certain types of market risk, including interest rate, commodity price or equity price risk. Mannatech does have investments but there has been no material change in its exposure to interest rate risk on its investments. Mannatech has not issued any debt instruments, entered into any forward or futures contracts, purchased any options or entered into any swaps. Mannatech is 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 may affect Mannatech's financial results. Changes in exchange rates may positively or negatively affect its financial results, as expressed in United States dollars. When the United States dollar increases against currencies in which products are sold or a weakening exchange rate against currencies in which Mannatech incurs costs, net sales or costs may be adversely affected. Mannatech has established policies, procedures and internal processes governing the management of its market risk and the use of any financial instruments to manage its 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 Mannatech's assets, obligations and projected transactions denominated in foreign currency. Based upon its overall currency rate exposure at December 31, 2000, Mannatech does not believe that its exposure to exchange rate fluctuations will have a material impact on the consolidated financial position, results of operations or cash flows. The foreign currencies in which Mannatech has exposure to foreign currency exchange rate risk include Australia, the United Kingdom and Japan. The high and low exchange rates to the United States dollar, for each of these countries, for the year ended December 31, 2000 were as follows: Country/Currency High Low ---------------- -------- -------- Australia/Dollar.................... $0.66850 $0.50730 United Kingdom/British Pound........ $1.65690 $1.39450 Japan/Yen........................... $0.00987 $0.00870 Given the uncertainty of the exchange rate fluctuation against the United States dollar, Mannatech cannot determine the dollar effect, if any, of the fluctuation on future business, product pricing, results of operations or financial condition. All statements other than historical information incorporated in this Item 7A are forward-looking statements. The actual impact of future market changes may differ materially due to, among other things, factors discussed in this report. Item 8.

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 operations, 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, 1999 and 2000, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2000, in conformity with accounting principles generally accepted in the United States of America. 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 of America, 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 our opinion. As discussed in Note 1 of the Notes to Consolidated Financial Statements, the Company changed its method of accounting for revenue recognition as a result of the adoption of Staff Accounting Bulletin No. 101, "Revenue Recognition in Financial Statements."

MANNATECH, INCORPORATED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS NOTE 1 ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 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 in the United States, Canada, Australia, the United Kingdom and Japan. Independent associates ("Associates") purchase products at wholesale prices 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. The Company has eight wholly owned subsidiaries located throughout the world. The wholly owned subsidiaries are as follows: Wholly-owned Subsidiary Date Operations Name Date Incorporated Location of Subsidiary Began - ----------------------- ----------------- ----------------------- ----------------- Mannatech Australia Pty April 22, 1998 St. Leonards, Australia October 1, 1998 Limited Mannatech Limited December 1, 1998 Republic of Ireland No operations Mannatech Ltd.

(ceased operations as of December 31, 2000) Mannatech Japan, Inc. January 21, 2000 Tokyo, Japan June 26, 2000 Mannatech Limited February 14, 2000 New Zealand No operations 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. 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 At December 31, 2000, accounts receivable consist of the overpayment of consumption tax paid in Japan, 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 amounts that are deemed uncollectible. F-7

MANNATECH, INCORPORATED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) At December 31, 1999, accounts receivable consist of 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 amounts that are deemed uncollectible. Inventories Inventories consist of raw materials and finished goods and are stated at the lower of cost (using standard costs, which approximates average costs) or market. Property and Equipment Property and equipment are stated at cost, less accumulated depreciation 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 the accompanying consolidated statements of operations. 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 its 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. During 2000, the Company recorded an impairment loss of $870,000 on fixed asset software. Other Assets Other assets consist primarily of deposits for building leases and a restricted term deposit in an Australian bank, of approximately $99,000 at December 31, 1999 and $84,000 at December 31, 2000. This term deposit matures every six months and is automatically renewed by the Company as security for the Australian building lease. Accounts Payable The Company records book overdrafts in its cash accounts as accounts payable. Accounts payable includes book overdrafts of $1,450,623 at December 31, 2000. Income Taxes The Company accounts for income taxes using the asset and liability approach for financial accounting and reporting. 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. F-8

MANNATECH, INCORPORATED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) Revenue Recognition The Company's revenues consist of sales from products sold, starter and renewal packs sold and shipping fees charged. Substantially all product sales are made to Associates at a published wholesale price. Net sales also reflect product returns and any related refunds. The Company also records a reserve for product returns based on historical experience. The Company adopted Staff Accounting Bulletin No. 101 "Revenue Recognition in Financial Statements" ("SAB 101") in the fourth quarter of 2000. Under SAB 101, the Company recognizes revenue for product sales upon the receipt of the products by the Associates. As a result of adopting SAB 101, the Company recorded a charge of $210,000, net of tax of $126,000 for the cumulative effect of this change at January 1, 2000. Beginning in 2000, the Company deferred all revenues until the Associate receives the shipment. The change in accounting method would not have a material effect on the Statements of Operations in 1999 and 1998 if adopted in those periods. The Company also 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 revenues contained in pack sales are amortized over a twelve- month period. As of January 1, 2001, the Company discontinued the inclusion of the event admission in the starter and renewal packs. Total net deferred revenue was $845,000 and $691,000 at December 31, 1999 and 2000, respectively. Shipping and Handling Cost In accordance with the Emerging Issues Task Force No. 00-10 "Accounting for Shipping and Handling Fees and Costs", the Company records freight and shipping revenues, collected from the Associate, as revenue. The Company records in- bound freight and shipping costs as a part of cost of sales and the Company records shipping and handling costs associated with shipping products to its Associates as selling and administrative expenses in the accompanying consolidated financial statements. Total shipping and handling costs included in selling and administrative expense was approximately $8.2 million, $9.1 million and $6.6 million for 1998, 1999 and 2000, respectively. 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 require 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 $3.8 million, $3.6 million and $5.3 million for 1998, 1999 and 2000, respectively. Literature and promotional items, called sales aids, are sold to Associates to support their sales efforts and are primarily included in inventories and charged to cost of sales when sold. F-9

MANNATECH, INCORPORATED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) 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 $391,000, $439,000 and $392,000 in 1998, 1999 and 2000, 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 $3.4 million, $3.6 million and $4.4 million in 1998, 1999 and 2000, 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 related 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 formulation stage has been completed. Such costs are amortized over the estimated useful life of the software, which is five years. Capitalized costs were approximately $929,000, $1.7 million and $681,000 in 1998, 1999 and 2000, respectively. Amortization expense related to capitalized software was approximately $346,000, $528,000 and $712,000 in 1998, 1999 and 2000, respectively. Earnings (Loss) per Share The Company calculates earnings (loss) 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 (loss) per share ("EPS") on the face of the consolidated statement of operations 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 based on 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 that the Company considers to be of high credit quality. The Company believes its notes receivables from shareholders 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 and accrued expenses, approximate their recorded values due to their relatively short maturities. Foreign Currency Translation The Australian and the United Kingdom subsidiaries' are limited service providers and their 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 revenues and expenses are translated at average exchange rates for the year. Translation (gains) and losses of Mannatech's foreign subsidiaries totaled approximately $17,000 ($176,000) and $345,000 in 1998, 1999 and 2000 respectively, and are included, in other expense, in the consolidated statements of operations. F-10

MANNATECH, INCORPORATED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) Accumulated Other Comprehensive Income (loss) The Japan subsidiary conducts substantially all of its business in Japanese Yen; therefore, the Company considers the Japanese Yen as it's functional currency. Its subsidiary's assets and liabilities are translated into United States dollars at exchange rates existing at the balance sheet dates, revenues and expenses are translated at weighted-average exchange rates, and shareholders' equity and intercompany accounts are translated at historical exchange rates. The foreign currency translation adjustment is recorded as a separate component of shareholders' equity and is included as accumulated other comprehensive income (loss) as required under Statement of Financial Accounting Standards No. 130 "Reporting Comprehensive Income." Comprehensive income (loss) is defined as the change in equity of a business enterprise during a period from transactions and other events and circumstances from nonowner sources and includes all changes in equity during a period. 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. 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 $12.0 million. The net proceeds to the Company were $9,240,958 after deducting deferred offering costs related to legal, accounting and printing fees of approximately $2.0 million, other costs of approximately $406,000 and the fee to the placement agent involved in the Offering of approximately $389,000, net of reimbursement of approximately $91,000 of expenses by the placement agent. The selling shareholders sold 1,556,016 shares of common stock, yielding gross proceeds of approximately $12.4 million. The net proceeds paid to the selling shareholders were approximately $12.0 million, after deducting the fee to the placement agent of approximately $498,000. 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 classified as held-to-maturity and are 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 accompanying statements of operations. F-11

MANNATECH, INCORPORATED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) At December 31, 2000, investments consist of an obligation of a United States Government sponsored enterprise, of $1,130, which matures in 2003 and is classified as held-to-maturity.

The note bears interest at 8.0% and was payable in monthly installments of approximately $16,000 through December 2000. NOTE 8 CAPITAL LEASE OBLIGATIONS In March and August 1998, the Company entered two new lease agreements totaling $631,000 and $841,000, respectively, with Banc One Leasing Corporation to fund the purchase of furniture and certain capital equipment for its laboratory facility and warehouse. The leases are collateralized by the leased assets, bear interest at 9.3%, are payable in thirty-six monthly installments and contain certain financial covenants which require the Company to maintain stated levels of debt to tangible net worth and an annual cash flow coverage ratio.

EXHIBIT 10.30 June 24, 1999 Mr. Ray Robbins, Individually and as President of Robbins Enterprises, Inc. 2201 Ingleside Grand Prairie, Texas 75050 RE: Buyback of Training Bonus Agreement by Mannatech, Incorporated Dear Mr. Robbins: This letter is to document the agreement between Mannatech, Incorporated ("Mannatech") and yourself (whether acting individually or on behalf of Robbins Enterprises, Inc., a Texas corporation which you control) (collectively, "Robbins") with regard to the repurchase of certain rights that you have to payments from Mannatech under an agreement dated March 23, 1995 between Robbins and Emprise International, now know as Mannatech ("March 1995 Agreement"). Under the terms of the March 1995 Agreement, as stated in Paragraph 3(d) thereof, you are entitled to receive training payments as specified therein ("Training Payments"). At the time that the March 1995 Agreement was entered into between the parties, Mannatech was a fledgling, domestic company. Mannatech, today, has grown significantly, operates in two foreign countries, and contemplates further international expansion. Robbins contends that the March 1995 Agreement entitles him to Training Payments respecting international business. The Company has taken the position that the March 1995 Agreement entitled Robbins only to business that was contemplated at the time of the agreement, such being respecting domestic and Canadian business. In order to settle this difference of opinion, Mannatech has offered to repurchase of the rights to Training Payments, whether based on foreign or domestic business, to which Robbins has agreed ("Repurchase Agreement"). Robbins, hereafter in corporate literature and presentations, will be referred to as a "founder" of Mannatech. The total amount of the Purchase Price for the Repurchase Agreement shall be the sum of $750,000.00 which shall be paid part in cash upon the execution of this Letter Agreement, with the balance being paid by an earnout. Upon the execution of this Letter Agreement, Mannatech shall tender, in good funds, the sum of $500,000.00 to Robbins as the Cash Portion of the Purchase Price of the Repurchase Agreement. As of the date of the execution of this Letter Agreement and 1

the receipt by him of the Cash Portion of the Purchase Price of the Repurchase Agreement, Robbins shall no longer be entitled to payments under the March 1995 Agreement, which shall in all respects be terminated as of that date. Robbins shall, thereafter be entitled to the Earnout Portion of the Purchase Price in an aggregate amount of $250,000.00, payable as follows: The Earnout Portion of the Purchase Price of the Repurchase Agreement shall be $250,000. On or before the thirtieth day of each month, commencing in July, 1999, and continuing on the same date of each subsequent month thereafter until July, 2001 Mannatech shall pay the sum of $10,000 ("Monthly Payment Amount") to Robbins. Accordingly, Robbins shall receive and continue to receive the Monthly Payment Amount until such time as the Earnout Portion of the Purchase Price shall have been paid in full. No interest shall accrue or be payable on the Earnout Portion of the Purchase Price of the Repayment Agreement. Robbins and Mannatech have previously entered into an agreement to terminate certain of the rights of Robbins, excluding the rights to receive Training Payments. This agreement, dated May 14, 1997 is attached hereto as Combined Exhibit "A" ("May 1997 Agreement"). The May 1997 Agreement terminated all prior agreements between the parties except that one covenant in the March 1995 Agreement requiring Mannatech to pay Training Payments to Robbins which remained in effect. Except as modified by this Letter Agreement, resulting in the termination of Training Payments to Robbins by Mannatech, the May 1997 Agreement shall remain in full force and effect and valid in every way. As a further inducement for Mannatech to enter into this Letter Agreement, Robbins, on behalf of himself and Robbins Enterprises, Inc. represents and warrants as follows: (a) That Robbins is the sole owner of the right to receive Training Payments, as currently continues to exist under the March 1995 Agreement, and that he has not transferred, assigned, pledged or impaired in any his right to transfer these rights back to Mannatech. (b) That upon the execution of this Letter Agreement, which shall operate as an Assignment to Mannatech, Mannatech shall have all and full right, title and interest in and to the Robbins Training Payment rights to the effect that neither he, nor any person, nor any entity shall have any right or claim of right to receive such Training Payments. (c) That there are, and will be at closing, no adverse or other claims to receipt of or title to the Training Payments, except as made by Robert Hydeman in his arbitration case against Robbins and Mannatech ("Hydeman Arbitration"), which claims shall have been settled or shall be settled contemporaneously with the execution of this Letter Agreement, nor will Robbins be upon notice of any threat of the same. And otherwise, no party shall have been granted any form of other right relating to receipt or right to receive the Training Payments. As of the execution and delivery by Robbins of this Letter Agreement, there will not be any action, suit or proceeding pending, or to the knowledge of the Robbins threatened, against or affecting the Training Payments or any portion thereof. All judicial proceedings concerning the Training Payments or any other dispute arising 2

from, inter alia, the Hydeman Arbitration will be finally dismissed, and terminated prior to or contemporaneously with the execution and delivery by Robbins of this Letter Agreement. (d) That Robbins is not currently in violation of or subject to any existing, pending or threatened investigations or inquiry by any governmental authority or to any remedial obligations under any applicable law. (e) That from and after the date hereof, up to and including the date upon which Robbins executes this Letter Agreement and receives the Cash Portion of the Purchase Price of the Repurchase Agreement, which in all events shall be prior to June 30, 1999, Robbins shall not sell, assign or create any right, title or interest whatsoever in or to the Training Payments, create or permit to exist any liens, encumbrances or charges thereon, without promptly discharging the same. (f) That Robbins shall properly pay, when due any tax liability resulting from and due any taxing authority on account of the effect of this Letter Agreement, and shall indemnify and hold Mannatech harmless from the same. Robbins further represents and warrants that he is an independent contractor of Mannatech for all purposes, including for federal and state income and other tax purposes. All of the representations, warranties, covenants, agreements and indemnities of Seller and Purchaser contained in this Agreement, to the extent not performed at the Closing, shall survive the Closing and shall not be deemed to merge upon the acceptance of the Deed of Purchaser. This Letter Agreement embodies and constitutes the entire understanding between the parties with respect to the transactions contemplated herein, and all prior or contemporaneous agreements, understandings, representations and statements (oral or written) are merged into this Letter Agreement, except as otherwise stated as to the survival of the effect of the May 1997 Agreement. The foregoing notwithstanding, nothing in this Letter Agreement shall be deemed to alter or amend any Associate Agreement of Robbins which creates an Associate position in the Mannatech downline, the obligation of Mannatech to reimburse or pay Robbins' reasonable travel expenses in connection with Mannatech business or to permit him to designate as Presidential to permit him to designate as Platinum Presidential (or the then highest rank of Mannatech Association position) the Top Gun associate position (Associate Control Number 727), reserving the right to designate at any later date the Duree/REI associate position (Associate Control Number 6103) and the Auge/REI associate position (Associate Control Number 994) as Platinum Presidential (or the then highest rank of Mannatech Associate position), provided such designation will not economically affect any Associate, rather only Mannatech. None of the terms of this Letter Agreement or any provision hereof may be waived, modified, amended, discharged or terminated except by an instrument in writing signed by the party against whom the enforcement of such waiver, modification, amendment, discharge or termination is sought, and then only to the extent set forth in such instrument. This Letter Agreement is for the sole benefit of Robbins and Mannatech, its successors and 3

assigns, and no other person shall be deemed to have any privity of contract hereunder, nor shall any other person be deemed to be a third party beneficiary hereunder. This Agreement shall be governed by and construed in accordance with the laws of the State of Texas. This Letter Agreement shall be binding upon and shall inure to the benefit of the parties and their respective heirs, executors, administrators, legal representatives, successors, and assigns. All references to the date of this Agreement or similar references shall be deemed to refer to the date, in point of time, on which the Seller and Purchaser have executed a copy of this Agreement, which shall be not later than June 30, 1999. With respect to the provisions of this Agreement, time is of the essence. However, if the final date of any period which is set out in any provision of this Agreement falls on a Saturday, Sunday or legal holiday under the laws of the United States, the State of Illinois or the State of Texas, then the time of such period shall be extended so that the last day of such period falls on the next day which is not a Saturday, Sunday or legal holiday. The offer to repurchase the Training Payments upon the terms and conditions set forth herein which is extended to Robbins by delivery of this Agreement to him shall expire and be automatically revoked and cancelled unless he shall have executed this Agreement and delivered at least one (1) copy to Seller on or before 1:00 P.M. on June 30, 1999. Very truly yours, MANNATECH, INCORPORATED By: /s/ Anthony E. Canale ---------------------------- Its: Chief Operating Officer ---------------------------- Agreed as of the 30th of June, 1999 /s/ Ray Robbins - ------------------------------------------ Ray Robbins, Individually and on behalf or Robbins Enterprises, Inc., a Texas Corporation. 4

Exhibit A AGREEMENT This Agreement ("Agreement") is made and effective this 14th day of May, 1997, by and between Mannatech, Incorporated ("Corporation"), a Texas corporation whose principal place of business is 600 S. Royal Lane, Suite 200, Coppell, Texas and Ray Robbins ("Consultant"), who resides at 2201 Ingleside, Grand Prairie, TX 75050. WITNESSETH: WHEREAS, the Corporation is in the business of operating a network marketing company which sells a proprietary line of dietary supplements, cosmetics and over-the-counter drugs ("Products") and which compensates its distributors ("Associates") by a defined compensation plan; WHEREAS, in connection with the development of its business the Corporation has entered into a confidential relationship with the Consultant whereby the Consultant will acquire or has acquired an intimate knowledge of the Corporation's business and will obtain or has obtained specialized skills. The Corporation will permit or has permitted the Consultant to have access to and to utilize the business goodwill, cost and pricing information, CONFIDENTIAL INFORMATION (as defined herein) and various trade secrets of the Corporation, including without limitation, marketing programs, business relationships, customer lists, and other compilations of information developed by the Corporation and essential to its business; WHEREAS, the Consultant is a key to the business of the Corporation and the Corporation will provide or has provided the Consultant with access to such CONFIDENTIAL INFORMATION and trade secrets in reliance upon the Consultant entering into this Agreement; and WHEREAS, in conjunction with the Consultant's access to and use of the CONFIDENTIAL INFORMATION and trade secrets of the Corporation, the Consultant has agreed to enter into this Agreement with the Corporation; WHEREAS, the Consultant and the Corporation have previously entered into a series of Agreements, attached hereto as Compiled Exhibit "A" ("Prior Agreements"), which the parties now desire to modify by this Agreement; NOW, THEREFORE, in consideration of the mutual covenants and agreements contained herein and upon the terms, conditions and provisions hereinafter set forth, the Corporation and the Consultant do hereby agree as follows: 5

ARTICLE I CONFIDENTIAL INFORMATION 1. The Corporation will provide or has provided the Consultant with specialized information concerning the products and the business operations of the Corporation. Irrespective of the term of consultancy, and in consideration of the Consultant's promises specified in Article II of this Agreement, the Corporation agrees to provide specialized training and instruction to the Consultant for the duties in consultation to the Corporation concerning the development of the Associate downline of the Corporation, recruitment and other matters as may come before the parties from time-to-time, and agrees to provide specialized training to the Consultant for such additional consulting duties as the parties may in good faith agree in the future. 2. During the course of the Consultant's engagement and training incident thereto the Consultant will be or was given access to the Corporation's CONFIDENTIAL INFORMATION concerning Products and the business operations of the Corporation. 3. The Consultant acknowledges that in the further course of the Consultant's engagement with the Corporation, the Consultant will gain a close, personal and special influence with the Corporation's customers and Associates and will be acquainted with all of the Corporation's business, particularly the Corporation's CONFIDENTIAL INFORMATION concerning the business of the Corporation and its affiliates. 4. For purposes of this Agreement "CONFIDENTIAL INFORMATION" shall mean and include information disclosed to the Consultant or known by the Consultant through the Consultant's engagement with the Corporation, not generally known in the Corporation's industry, about the Corporation'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 Consultant recognizes that the Consultant's position with the Corporation is one of the highest trust and confidence by reason of the Consultant's access to the CONFIDENTIAL INFORMATION and the Consultant agrees to use the Consultant's best efforts and will exercise utmost diligence to protect and safeguard the CONFIDENTIAL INFORMATION. In this respect, the Consultant agrees that fulfilling the obligations of the Agreement is part of the Consultant's job responsibilities with the Corporation for which the Consultant has been retained as an Consultant and for which the Consultant has received consideration therefor. 6

6. Except as may be required by the Corporation in connection with and during the Consultant's engagement with the Corporation, or with the express written permission of the Corporation, the Consultant shall not, either during the Consultant's work as an consultant with the Corporation or at any time thereafter, directly or indirectly, download, printout, copy, remove from the premises of the Corporation, use for the Consultant's own benefit or for the benefit of another, or disclose to another, any CONFIDENTIAL INFORMATION of the Corporation, its customers, contractors or of other with which the Corporation has a business relationship. 7. Consultant 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 Consultant, made available to the Consultant or otherwise coming into the Consultant's possession while engaged by the Corporation concerning any process, apparatus or products manufactured, sold, used, developed, investigated or considered by the Corporation concerning the CONFIDENTIAL INFORMATION or concerning any other business or activity of the Corporation shall remain at all times the property of the Corporation and shall be delivered to the Corporation upon termination of the Consultant's engagement with the Corporation or at any other time upon request. 8. The Consultant agrees that, during the term of the Consultant's engagement with the Corporation or upon termination thereof, and if requested by the Corporation to do so, the Consultant will sign an appropriate list of any and all CONFIDENTIAL INFORMATION of the Corporation of which the Consultant has knowledge or about which the Consultant has acquired information. ARTICLE II DUTIES AND NONCOMPETITION 1. Consultant's duties shall be those assigned agreed to between the Corporation from time-to-time, but shall include development of recruiting and Associate downline matters. Nothing contained in this agreement is intended to abrogate or affect the right of the Consultant to be paid in accordance with the compensation plan of the Corporation, as the same if from time-to-time in effect. The Consultant agrees that the Consultant will serve the Corporation diligently, faithfully and to the best of the Consultant's ability during the term of the Consultant's engagement with the Corporation, which shall be at the will of the Corporation, and which shall further be subject to the announced Policies and Procedures of the Corporation which shall from time-to-time be in effect. The Consultant shall devote reasonable time, efforts, ability and attention to the business of the Corporation and the performance of the Consultant's duties, understanding that the Consultant is an independent contractor for all purposes, including Federal Income Tax purposes. 2. Consultant acknowledges and understands that from time to time the Consultant's duties will require the Consultant to work at non-company locations. In such instance, the 7

Consultant agrees to comply with all of the policies, procedures and directives relevant to working at such non-company locations. 3. Consultant represents and admits that in the termination of the Consultant's engagement for any reason whatsoever, the Consultant's experiences and capabilities are such that the Consultant can obtain engagement 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 Consultant from earning a livelihood. 4. Consultant acknowledges that the Consultant will receive special knowledge and specialized training from the Corporation, included in which is the CONFIDENTIAL INFORMATION identified in Article I above. The Consultant further acknowledges that training provided by the Corporation and the CONFIDENTIAL INFORMATION is valuable to the Corporation and, therefore, the Corporation's investment in the training and the protection and maintenance of the CONFIDENTIAL INFORMATION constitutes a legitimate interest to be protected by the Corporation by the covenant not to compete, set forth in Paragraph 5 of Article II of this Agreement. 5. The Consultant therefore agrees that during the term of the Consultant's engagement with the Corporation and for a period of one (1) year (or a shorter period with the written consent of the Corporation) after the Consultant shall cease to be engaged by the Corporation for any reason, the Consultant shall not, directly or indirectly engage in or solicit, as an owner, principal, director, officer, partner, consultant, engaged, distributor, agent of any business which competes with that of the Corporation in the United States of America. Additionally, the Consultant agrees that he/she shall not, without the prior written consent of the Corporation, for a period of one (1) year from the termination of the Consultant's engagement with the Corporation (or a shorter period with the written consent of the Corporation) in the United States of America: a. Solicit any current or prospective customer, Associate, partner, principal or investor of the Corporation; b. Directly or indirectly be engaged by, invest in, manage or engage in any business that is competitive with the business of the Corporation; c. Either as an individual, a partner, or a joint venturer, or in any other capacity whatsoever, directly or indirectly accept engagement with or render services to any business that markets products and services in competition with those marketed by or under development by the Corporation at the time of the termination of the Consultant's engagement with the company or offers its goods and/or services for sale via a sales mechanism such as multi- level marketing, network marketing or direct marketing. As set forth above, the Consultant acknowledges that this noncompletion covenant is 8

ancillary to or a part of an otherwise enforceable agreement, such being the general agreement of Engagement and its related agreements concerning confidentiality and non-disclosure of CONFIDENTIAL INFORMATION and non- solicitation, at the time that this noncompetiton 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 Corporation, 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 Corporation, 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. 6. The Consultant agrees that during his engagement with the Corporation and for a period of one (1) year after termination of such engagement, he/she shall not, on his/her own behalf or on behalf of any other person or business entity, hire solicit, seek to hire or offer engagement to any person who now or later works for the Corporation, or who is a current or prospective employee of the Corporation. The Consultant further agrees that he will not in any other manner attempt, directly or indirectly, to influence, entice or encourage any person who now or later works for the Corporation, or who is a current or prospective employee of the Corporation, to leave the engagement of the Corporation during the operative term of this covenant of Non-Solicitation: a. Any corporation, partnership, association, agency, or business, engaged in the business of multi-level marketing, network marketing and/or direct selling or in the marketing, sales and distribution of dietary and nutritional supplement products in competition with the Corporation or any of its affiliates at the time the Consultant ceased to be engaged by the Corporation; or b. Any corporation, partnership, association, agency, or business, known to the Consultant to be an Associate or customer of the Corporation as of the date of the Consultant's cessation of engagement by the Corporation or with whom the Consultant had contact during, and by reason of, the Consultant's engagement by the Corporation. 7. Consultant agrees that in the highly competitive business in which the Corporation is engaged, personal contact is of primary importance in securing new and retaining present Associates and customers. The Consultant also agrees that the Corporation has a legitimate interest in maintaining its relationships with its Associates and customers and that it would be unfair for the Consultant to solicit the business of the Corporation's Associates and customers and exploit the personal relationships the Consultant develops with the Corporation's Associates and customers by virtue of the Consultant's access to the Corporation's customers as a result of the Consultant's engagement by the Corporation. 8. The Consultant therefore agrees that for a period of one (1) year after the 9

Consultant shall cease to be engaged by the Corporation for any reason, the Consultant shall not solicit, in competition with the Corporation, the business of any person, company, firm, corporation, partnership, association, agency, or business, known to the Consultant to be an Associate and/or customer of the Corporation as of the date of the Consultant's cessation of engagement by the Corporation or with whom the Consultant had contact during, and by reason of, the Consultant's engagement by the Corporation. 8. The Consultant further agrees that for a period of one (1) year after the Consultant shall cease to be engaged by the Corporation for any reason, the Consultant will not, either directly or indirectly, through any person, firm, association or corporation with which the Consultant is now or may hereafter become associated, cause, influence or induce any present or future employee of the Corporation or its affiliates to leave the employ of the Corporation or its affiliates to accept engagement with the Consultant or with such person, firm, association, or corporation with whom the Consultant may then be affiliated. 10. The foregoing covenants not to compete 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 award or decree in arbitration or any judgement 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 Consultant shall not be a defense for the Consultant to claims arising from the Corporation's enforcement of the provisions of this paragraph. Should the Consultant violate the noncompletion 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 Consultant began such violation until the Consultant permanently ceases such violation. 11. Irrespective of the term of engagement under this Agreement, and in consideration of the promises specified in Article II of this Agreement, the Corporation agrees as follows: a. To issue, within thirty days of the date of this Agreement, capital stock of the Corporation in an amount of 939,333 shares, it being agreed that notwithstanding any provision contained herein to the contrary, the Consultant agrees to be bound by the underwriting agreements or requirements by and between the Corporation 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 of stock conferred hereby or which is otherwise owned by the Consultant, the Consultant agrees to further be bound by such requirements, limitations, restrictions, and/or agreements, as agreed to by the Corporation. You hereby appoint Mannatech (the Corporation) as your attorney-in-fact to execute all documents on your behalf concerning agreements offering the shares of stock which are conferred hereby, including, without limitation, those agreements with the Underwriter, referenced above; which the parties agree is of a value in excess of $1,000.00. 10

b. To provide specialized training as specified herein; c. To provide the Consultant with access to the Corporation'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 Corporation as is relevant to the Consultant's engagement in the opinion of the Corporation. 12. The Consultant agrees that the agreements, noncompetition 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 Consultant against the Corporation, whether predicated on this agreement or otherwise, shall not constitute a defense to the enforcement by the Corporation of the covenants and agreements of the Consultant contained in the noncompetiton, 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. 13. The Consultant 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 Consultant could not take without violating any provision of this Agreement. 14. The Consultant recognizes and acknowledges that damages in the event of his breach of certain provisions of this Engagement Agreement would be inadequate, and the Consultant agrees that the Corporation, 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 Consultant of any one or more of the provisions contained in Article II hereof. Arbitration shall be the exclusive remedy for any and all disputes, claims or controversies, whether statutory, contractual or otherwise, between the Corporation and the Consultant concerning the Consultant's engagement or the termination thereof. In the event either party provides a Notice of Arbitration of Dispute to the other party, the Corporation and the Consultant agree to submit such dispute or controversy, whether statutory or otherwise, to an arbitrator selected from a panel of arbitrators of the American Arbitration Association located in Dallas, Texas. The effective rules 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 11

provisions, the arbitrator is specifically empowered to decided any question pertaining to limitations, and 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. ARTICLE III ASSIGNMENT OF INVENTIONS 1.
