MANNATECH, INCORPORATED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) 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 high-quality, proprietary nutritional supplements, topical products and weight-management products primarily through a network marketing system operating in the United States, Canada, Australia, the United Kingdom and Japan. Independent associates ("Associates") purchase products at wholesale, for the primary purpose of selling to retail consumers or for personal consumption. Active Associates earn commissions on their downline growth and sales volume. In June 2001, the Company introduced its member program specifically designed for consumers ("Members") to purchase products for personal consumption at a discount but not to participate in the various incentive programs. The Company's nine wholly-owned subsidiaries are as follows: Wholly-owned subsidiary name Date incorporated Location of subsidiary Date operations began ---------------------------- ----------------- ---------------------- --------------------- Mannatech Australia Pty Limited April 22, 1998 St. Leonards, Australia October 1, 1998 Mannatech Limited December 1, 1998 Republic of Ireland No operations Mannatech Ltd. November 18, 1998 Aldermaston, Berkshire November 15, 1999 U.K. Mannatech Payment Services Incorporated April 11, 2000 Coppell, Texas June 26, 2000 Mannatech Foreign Sales Corporation May 1, 1999 Barbados May 1, 1999 Internet Health Group, Inc. (ceased May 7, 1999 Coppell, Texas December 20, 1999 operations as of December 29, 2000) Mannatech Japan, Inc. January 21, 2000 Tokyo, Japan June 26, 2000 Mannatech Limited February 14, 2000 New Zealand No operations Mannatech Products Company, Inc. April 17, 2001 Coppell, Texas No operations The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of Company's management, the accompanying unaudited consolidated financial statements contain all adjustments, consisting of normal recurring adjustments, considered necessary for a fair statement of the Company's financial information as of and for the periods presented. The consolidated results of operations of any interim period are not necessarily indicative of the consolidated results of operations to be expected for the fiscal year. For further information, refer to the Company's consolidated financial statements and accompanying footnotes included in their annual report on Form 10-K for the year ended December 31, 2000. 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. Revenue Recognition The Company's revenues primarily consist of sales from products, starter and renewal packs and shipping fees. Substantially all product sales are sold to Associates at published wholesale prices and to Members at published discounted retail prices. Net sales include a reserve for estimated product returns and any related refunds, which are based on its historical experience. The Company adopted Staff Accounting Bulletin No. 101 "Revenue Recognition in Financial Statements" ("SAB 101") in the fourth quarter of 2000. As a result of adopting SAB 101, the Company has restated its 2000 quarterly financial information and recorded a one-time charge of $210,000, net of tax of $126,000 for 4

the cumulative effect of this accounting change at January 1, 2000. Beginning in 2000, the Company defers all of its revenues until the consumer receives the products shipped. The Company also defers a portion of its revenue received from sales of starter and renewal packs, which are in excess of the average cumulative wholesale value of all of the individual items included in such packs and amortizes such deferrals over a twelve-month period. Total deferred revenue was $691,000 at December 31, 2000 and $736,000 at September 30, 2001. Shipping and Handling Costs In accordance with the Emerging Issue Task Force No. 00-10 "Accounting for Shipping and Handling Fees and Costs," the Company records freight and shipping revenues collected from its Associates and Members, as revenue. The Company records the in-bound freight and shipping costs as a part of cost of sales and records the shipping and handling costs associated with shipping its products to all of its consumers as selling and administrative expenses. Total shipping and handling costs included in selling and administrative expenses was approximately $1.2 million and $1.3 million for the three-months ended September 30, 2001 and 2000, respectively and $4.3 million and $5.8 million for the nine-months ended September 30, 2001 and 2000, respectively. Earnings 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 the period. At September 30, 2000, all of the 3,863,952 common stock options were excluded from the diluted EPS calculation and at September 30, 2001, all of the 3,764,307 common stock options and 213,333 warrants were excluded from the diluted EPS calculation, as their effect was antidilutive. The following data shows the amounts used in computing earnings (loss) per share and their effect on the weighted-average number of common shares of dilutive common share equivalents for the three-months ended September 30, 2000 and 2001. The amounts are rounded to the nearest thousand except for per share amounts. 2000 2001 ----------------------------------------- ---------------------------------------- Net loss Shares Per share Net loss Shares Per share (Numerator) (Denominator) amount (Numerator) (Denominator) amount ----------- ------------- --------- ----------- ------------- --------- Basic EPS: Net loss available to to common shareholders $(1,203) 24,984 $(0.05) $(305) 24,367 $(0.01) Effect of dilutive securities: Stock options/warrants -- -- -- -- ------- ------ ----- ------ Diluted EPS: Net loss available to common shareholders plus assumed conversions $(1,203) 24,984 $(0.05) $(305) 24,367 $(0.01) ======= ====== ====== ===== ====== ====== 5

As a result, the Company entered into Separation Agreements with each of them. Under the terms of their agreements, the executives are bound by certain non-compete and confidentiality clauses and the Company agreed to pay them an aggregate amount of $1.9 million in 2001, $1.6 million in 2002, $850,000 in 2003 and $150,000 in 2004. The payments consist of compensation related to the cancellation of their employment agreements, accrued vacation, health insurance and automobile expenses. The Company also agreed to grant Mr. Canale 213,333 warrants, Ms. Varner a total of 163,333 stock options and Mr. Cobb a total of 60,000 stock options, all at exercise prices ranging from $1.75 to $4.00. As of September 30, 2001, none of these options or warrants had been exercised. The warrants and stock options vest on the date they were granted and are exercisable for ten years. In the second quarter of 2001, the Company recorded a one-time charge for all of these separation agreements of which $2.7 million remained unpaid as of September 30, 2001. 6

In September 2001, the Company amended its agreement with a high-level Associate, shareholder and advisory board member to promote the Company and develop downline growth in Japan. The amendment further clarified that the Company would pay this Associate a royalty of $5.00 per each specific promotional materials sold, by the Company, up to a maximum of $1.6 million. The Company does not expect to incur any royalty expense associated with this agreement until the first quarter of 2002. NOTE 5 TRANSACTIONS WITH RELATED PARTIES On September 24, 2001, the Company amended their agreement with Mr. Charles Fioretti to contingently release Mr. Fioretti from his Lockup and Repurchase Agreement in which the Company originally agreed to buy, on a monthly basis, up to $1.0 million worth of his stock valued at 90% of the fair market value so that Mr. Fioretti could sell 3,500,000 of his common shares to Mr. J. Stanley Fredrick. Under the terms of their agreement, Mr. Fredrick agreed to purchase 3,500,000 shares of Mr. Fioretti's stock, and Mr. Fioretti agreed to transfer all of the voting rights associated with his remaining shares to Mr. Fredrick. In addition, Mr. Fredrick has the right of first refusal to acquire the remaining 690,848 shares from Mr. Fioretti. On September 28, 2001, the Company's Board of Directors appointed Mr. Fredrick to the Board of Directors to fill the vacancy created when Mr. Fioretti resigned in August 2001. On September 28, 2001, the Company entered into an agreement with Mr. Ray Robbins, a high-level Associate, shareholder and board member, to sell him all of the Company's 815,009 shares of treasury stock at $1.00 per share. The Company recorded the sale and a receivable due from a shareholder on September 30, 2001. The receivable was non-interest bearing and paid in full in October 2001. On October 1, 2001, the Company entered into a two-year Consulting and Lockup Agreement with Mr. Fredrick. This agreement automatically renews annually unless thirty-day written notice is given to all parties. Under the terms of this agreement, Mr. Fredrick will provide advice and perform various functions for the Board of Directors for which the Company will pay Mr. Fredrick a total of $185,000 per year. In addition, under this agreement, Mr. Fredrick is prohibited from selling his shares, unless approved by the Company's Board of Directors. NOTE 6 RECENT ACCOUNTING PRONOUNCEMENTS In July 2001, the Financial Accounting Standards Board issued Statements of Financial Accounting Standards No. 141 ("SFAS 141") "Business Combinations" and No. 142 ("SFAS 142") "Goodwill and Other Intangibles Assets." SFAS 141 supercedes Accounting Principles Board Opinion No. 16 "Business Combinations." The most significant changes made by SFAS 141 are that it requires that the purchase method of accounting be used for all business combinations initiated after June 30, 2001, establishes specific criteria for recognition of certain intangibles assets separately from goodwill and requires the immediate write-off of unallocated negative goodwill. SFAS 142 supercedes Accounting Principles Board Opinion No. 17 "Intangible Assets." SFAS 142 is effective for fiscal years beginning after December 15, 2001. SFAS 142 prohibits goodwill and indefinite lived intangible assets from being amortized and requires them to be annually tested for impairment at each reporting unit level. In addition, SFAS 142 removes the limitation of forty years for the useful lives of finite intangible assets. In June 2001, the Financial Accounting Standards Board issued Statements of Financial Accounting Standards No. 143 ("SFAS 143") "Accounting for Asset Retirement Obligations" and in October 2001, issued No. 144 ("SFAS 144") "Accounting for the Impairment or Disposal of Long-Lived Assets." SFAS 143 amends SFAS 19, "Financial Accounting and Reporting by Oil and Gas Producing Companies" and is effective for fiscal years beginning after June 15, 2002. This statement requires that the fair value of a liability for an asset retirement obligation be recognized in the period in which it is incurred if a reasonable estimate of fair value can be determined. In addition, SFAS 143 requires the associated asset retirement costs to be capitalized as part of the carrying amount of the long-lived asset. SFAS 144 supercedes SFAS No. 121 "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of" and Accounting Principles Board Opinion No. 30 "Reporting Results of Operations- 7

Reporting the Effects of Disposal of a Segment of a Business." SFAS 144 is effective for fiscal years beginning after December 15, 2001. SFAS 144 requires that impaired long-lived assets be measured at the lower of carrying amount or fair value less costs to sell, regardless if they are reported in continuing operations or in discontinued operations. In addition, discontinued operations should no longer be measured at net realizable value or include amounts for operating losses that have not yet occurred. Finally, SFAS 144 broadens the reporting of discontinued operations to include all components of an entity with operations that can be distinguished from the rest of the entity and that will be eliminated from the ongoing operations of the entity in a disposal transaction. The Company believes the above pronouncements will have no significant effect on its consolidated financial positions, results of operations or cash flows. NOTE 7 SUBSEQUENT EVENTS On October 1, 2001, the Company entered into an employment agreement with Ms. Bettina S. Simon to serve as the new Senior Vice President and General Counsel. Under the terms of the employment agreement, Ms. Simon will be paid an annual base salary of $200,000 and was granted 50,000 stock options, which vest over three-years and are exercisable over ten years at a stock price of $1.07 per share. The employment agreement has no fixed term; however, if cancelled without cause, Ms. Simon will be entitled to receive between three to six months of her annual base salary. On November 1, 2001, the Company granted 625,000 stock options to various executive officers. The options vest over three years, expire in ten years and are exercisable at $2.69 per share. Item 2. 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 its results of operations for the three and nine-months ended September 30, 2001 compared to the same periods in 2000. The Consolidated Financial Statements and related Notes should be referred to in conjunction with this discussion. 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 its high-quality, proprietary nutritional supplements, topical products and weight-management products primarily through a worldwide network marketing system operating in the United States, Canada, Australia, the United Kingdom and Japan. Currently Mannatech has approximately 202,000 active members and associates as of September 30, 2001 compared to approximately 274,000 active associates as of September 30, 2000. Mannatech defines an active associate or member as one having purchased products within the last twelve months. Members may purchase Mannatech's high-quality proprietary products for personal consumption at a discount but not participate in the various incentive programs. Mannatech's earnings (loss) per share remained at ($0.11) for each of the nine-months ended September 30, 2001 and for the comparable period in 2000, respectively in spite of recording a one-time charge of $3.4 million, in the second quarter of 2001, which related to the resignations of various former executives with employment agreements. In addition, Mannatech reported a decrease in net sales, which was directly attributed to a 26% decrease in Mannatech's active associate and member base. For the nine-months ended September 30, 2001, Mannatech would have reported net income of $731,000, exclusive of the $3.4 million one-time severance charge and continues to report income from operations for its North American operations. The net loss for 2000 totaling ($2.7 million) primarily related to a decrease in net sales, incurring approximately $4.4 million related to international expansion into the United Kingdom and Japan, and continuing to fund operations for its Internet subsidiary, Internet Health Group, Inc, which ceased operations on December 29, 2000. 8

Beginning in February 2001, Mannatech increased the shipping fees it charges to consumers and in March 2001, Mannatech increased the sale prices of some of its finished goods. The price increase on certain finished goods was Mannatech's first price increase since its inception in 1993. In June 2001, Mannatech introduced its member program and announced the hiring of new general managers for both its Australia and Japan operations, which it believes will help in strengthening its international operations. In addition, in the second quarter of 2001, Mannatech implemented some new incentive programs specifically designed to reward its entry-level associates faster, increase its active associate base and boost net sales. In October 2001, Mannatech unveiled its strategy for its new global compensation plan that will help to refocus its associates to primarily concentrate on Mannatech's performance and leadership incentive programs. Overall, Mannatech believes the changes to its compensation plan will better reward its associates and continue to pay approximately 42% of commissionable sales as compensation expense to its active associates. Net sales by country, as a percentage of consolidated net sales, including the Japan operations, which began operations on June 26, 2000, are as follows: Nine-months ended September 30 U.S. Canada Australia U.K. Japan Total - ------------------------------ ----- ------ --------- ---- ----- ------ 2001............. 77.0% 14.7% 3.4% 0.9% 4.0% 100.0% 2000............. 77.1% 13.4% 6.3% 1.2% 2.0% 100.0% Mannatech believes that it continues to provide the highest-quality of products to its consumers, which helps the consumer achieve optimal health and wellness. Mannatech also believes it only introduces products that help meet a current demand in the wellness industry at the highest quality available. Recently Mannatech introduced four new products including: o ImmunoStart(TM), which was introduced in October 2000, as a chewable tablet that aids in energy levels and helps the immune system. o Glyco-Bears(R), which was introduced in March 2001 as a new chewable multivitamin for children. Mannatech believes the chewable vitamin will help supplement children's diets and aid in their overall health and wellness. o Glycentials(TM), which was introduced in August 2001 as an antioxidant-rich multivitamin/mineral formula that helps to provide vitamin and mineral support. Mannatech believes this multivitamin will aid in ones overall health and wellness. o CardioBALANCE (TM), which was introduced in October 2001 to provide a wide range of certain nutritional benefits specifically designed to aid in the cardio-vascular system. Mannatech primarily derives its revenues from sales of its products and starter and renewal packs. Starter and renewal packs include some combination of Mannatech's proprietary products and promotional materials. An active associate who purchases a starter or renewal pack is entitled to purchase Mannatech's high-quality proprietary products at wholesale prices and earn various incentives and bonuses. In June 2001, Mannatech introduced its member program, which allows a member to purchase its high-quality proprietary products at 95% of the suggested retail price or 86% of the suggested retail price for an automatic monthly order. Mannatech offers comparable starter and renewal packs in each country in which it does business; however, due to different regulatory guidelines in each country, 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 9

the consumer receives the products shipped. The adoption of SAB 101 resulted in a one-time 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 are between 60% and 100% of the total wholesale value of the packs. The remainder of the total wholesale value, if any, consists of various promotional materials. Mannatech defers revenue over a twelve-month period for revenue received from the sale of its associate packs to the extent that the sales price exceeds the sum of the total average wholesale value of all of the individual items included in such packs. Total deferred revenue was approximately $691,000 at December 31, 2000 and $736,000 at September 30, 2001. Mannatech compensates its active associates by paying them commissions and incentives, which is its most significant expense. The commission structure is designed to not materially exceed 42% of commissionable net sales. In March 2001, Mannatech announced the following two incentive bonus programs for its active associates: o The Power Plan incentive bonus, which pays active associates for enrolling six All-Star associates; and o The Team incentive bonus, which pays active associates for meeting and maintaining certain purchasing levels in their organizations. Mannatech believes these incentive programs will ultimately pay more commissions to the entry-level associate faster. In October 2001, Mannatech announced that its strategy for its new compensation plan would help to refocus its associates to concenrate on its leadership and performance incentive programs; however, none of these changes to its compensation plan are expected to significantly change the total commissions paid as a percentage of commissionable net sales. Commissions and incentives paid to active associates are based on the following criteria: o associates placement and position within the compensation plan; o volume of their direct commissionable net sales; o number of new enrolled associates; and o achievement of certain levels to qualify for various incentive programs. In 2001, Mannatech believes its United States federal statutory tax rate will remain at 34%. Mannatech also pays taxes in various state jurisdictions at an approximate average effective tax rate of 3%. Mannatech expects to pay taxes in Australia, the United Kingdom and Japan at statutory tax rates ranging from 31% to 42%. The payment of such foreign taxes could result in foreign tax credits that would reduce the amount of United States taxes owed; however, Mannatech may not be able to fully-utilize all of such foreign tax credits in the United States. Mannatech has also incurred net operating losses from its Japan subsidiary that may not be fully realizable in the future. 10

Net sales decreased (19.0%) to $30.3 million for the three-months ended September 30, 2001 from $37.4 million for the comparable period in 2000. This decrease was primarily composed of a decrease of 26% in its active associate base, which was partially offset by a 7% increase in the sales prices of some of its finished goods implemented in March 2001and the introduction of several new products including ImmunoStart(TM), Optimal Health Pack (TM), GlycoBears(R) and Glycentials(TM). Cost of sales. Cost of sales decreased (17.6%) to $5.6 million for the three-months ended September 30, 2001 from $6.8 million for the comparable period in 2000. As a percentage of net sales, cost of sales increased to 18.4% for the three-months ended September 30, 2001 from 18.1% for the comparable period in 2000. The increase in cost of sales as a percentage of net sales was primarily due to a write-off of some expected spoilage and obsolescence of products totaling $525,000 and a change in the product mix of finished goods sold. The dollar decrease was primarily due to a decrease in the volume of finished goods sold, which was partially offset by the write-off of certain products. Commissions. Commissions consist of payments to active associates for their sales activity and downline growth. Commissions decreased (20.3%) to $12.2 million for the three-months ended September 30, 2001 from $15.3 million for the comparable period in 2000. As a percentage of net sales, commissions slightly decreased to 40.2% for 11

the three-months ended September 30, 2001 from 40.9% for the comparable period in 2000. The decrease was the direct result of a decrease in commissionable net sales and a 7% increase in the sales prices of some of its finished goods. Gross profit. Gross profit decreased (18.3%) to $12.5 million for the three-months ended September 30, 2001 from $15.3 million for the comparable period in 2000. As a percentage of net sales, gross profit slightly increased to 41.4% for the three-months ended September 30, 2001 from 41.0% for the comparable period in 2000. These changes were primarily attributable to the factors described above. Selling and administrative expenses. Selling and administrative expenses are a mixture of both fixed and variable expenses and include compensation, shipping and freight and marketing expenses. Selling and administrative expenses decreased (11.1%) to $7.2 million for the three-months ended September 30, 2001 from $8.1 million for the comparable period in 2000. As a percentage of net sales, selling and administrative expenses increased to 23.7% for the three-months ended September 30, 2001 from 21.6% for the comparable period in 2000, which was the result of Mannatech's inability to reduce some fixed and semi-variable expenses associated with the decrease in net sales. The dollar decrease was primarily due to the following: o a decrease of ($700,000) in compensation and related employee benefits due to the reduction of employees, including the resignation of various executives; o a decrease of ($404,000) in marketing related expenses, which was the result of recording a car incentive bonus and elimination of various events for its Japan operations; o the above were partially offset by an increase of $226,000 in freight cost as a result of opening its Japan operations. Other operating costs. Other operating costs include utilities, depreciation, travel, office expenses and printing expenses. Other operating costs decreased (35.3%) to $5.5 million for the three-months ended September 30, 2001 from $8.5 million for the comparable period in 2000. As a percentage of net sales, other operating costs decreased to 18.2% for the three-months ended September 30, 2001 from 22.9% for the comparable period in 2000. The decrease was primarily due to the following: o a decrease of ($870,000) related to variable expenses associated with a decrease in net sales and the curtailment of certain operating expenses; o a decrease of ($1.3 million) relating to the reduction in long-distance telephone expenses, postage and international travel related to the international expansion that was substantially completed by the end of 2000; and o a decrease of ($835,000) related to the completion of several projects by outside consultants. Interest income. Interest income decreased (61.9%) to $53,000 for the three-months ended September 30, 2001 from $139,000 for the comparable period in 2000. As a percentage of net sales, interest income decreased to 0.2% for the three-months ended September 30, 2001 from 0.4% for the comparable period in 2000. The decrease was due to using investments to fund current year operations. Interest expense. Interest expense decreased (40.0%) to $9,000 for the three-months ended September 30, 2001 from $15,000 for the comparable period in 2000. As a percentage of net sales, interest expense decreased to 0.0% for the three-months ended September 30, 2001 from (0.1%) for the comparable period in 2000. The decrease was primarily due to Mannatech paying off an existing note and two capital leases. Other expense, net. Other expense, net consists of foreign currency translation adjustments relating to the United Kingdom and Australia operations and miscellaneous non-operating items. Other expense, net decreased to ($30,000) for the three-months ended September 30, 2001 from ($250,000) for the comparable period in 2000. As a percentage of net sales, other expense, net decreased to (0.1%) for the three-months ended September 30, 2001 from 12

(0.7%) for the comparable period in 2000. For the three-months ended September 30, 2001, other expense, net consisted primarily of currency translation adjustments. For the three-months ended September 30, 2000, other expense, net consisted of currency translation adjustments and a loss from the abandonment of certain fixed assets. Income tax (expense) benefit. Income tax (expense) benefit was ($182,000) for the three-months ended September 30, 2001 and $357,000 for the comparable period in 2000. Mannatech's effective tax rate increased to (148.0%) for the three-months ended September 30, 2001 from 22.9% for the comparable period in 2000. Mannatech's effective tax rate increased primarily as a result of Mannatech's inability to recognize foreign income tax benefits relative to its Japan operations. Cumulative effect of accounting change, net of tax. In the fourth quarter of 2000, Mannatech adopted SAB 101, which resulted in a one-time charge of $210,000, net of tax of $126,000 for the cumulative effect of the accounting change. SAB 101 required Mannatech to defer the recognition of revenues until the consumers receive their products shipped. Net loss. Net loss decreased (74.6%) to ($305,000) for the three-months ended September 30, 2001 from ($1.2 million) for the comparable period in 2000. As a percentage of net sales, the net loss decreased to (1.0%) for the three-months ended September 30, 2001 from (3.2%) for the comparable period in 2000. The decrease was due to the following: o curtailment of various operating expenses; o no longer incurring expenses related to its Internet subsidiary; o a 19% decrease in net sales; and o substantial completion of its planned international expansion into three foreign countries. Nine-months ended September 30, 2001 compared with the nine-months ended September 30, 2000 Net sales. Net sales decreased (16.5%) to $97.0 million for the nine-months ended September 30, 2001 from $116.1 million for the comparable period in 2000. This decrease was primarily composed of a decrease of 26% in is active associate base, which was partially offset by a 7% sales price increase in some of its finished goods implemented in March 2001, a $3.7 million increase from opening Japan on June 26, 2000 and the introduction of several new products including ImmunoStart(TM), Optimal Health Pack(TM), GlycoBears(R) and Glycentials(TM). Cost of sales. Cost of sales decreased (16.6%) to $17.1 million for the nine-months ended September 30, 2001 from $20.5 million for the comparable period in 2000. As a percentage of net sales, cost of sales slightly increased to 17.7% for the nine-months ended September 30, 2001 from 17.6% for the comparable period in 2000. The slight increase in cost of sales as a percentage of net sales was primarily due to the write-off of products for spoilage and obsolescence, a change in the product mix of finished goods sold, partially offset by a 7% price increase for some of its finished goods that was implemented in March 2001. The dollar decrease was due to a decrease in the volume of finished goods sold. Commissions. Commissions consist of payments to active associates for sales activity and downline growth. Commissions decreased (18.6%) to $38.5 million for the nine-months ended September 30, 2001 from $47.3 million for the comparable period in 2000. As a percentage of net sales, commissions slightly decreased to 39.6% for the nine-months ended September 30, 2001 from 40.8% for the comparable period in 2000 due to a 7% increase in the sale prices of some of its finished goods. The dollar decrease was the direct result of a decrease in commissionable net sales. Gross profit. Gross profit decreased (14.3%) to $41.4 million for the nine-months ended September 30, 2001 from $48.3 million for the comparable period in 2000. As a percentage of net sales, gross profit increased to 42.7% for the nine-months ended September 30, 2001 from 41.6% for the comparable period in 2000. These changes were primarily attributable to the factors described above. 13

Selling and administrative expenses. Selling and administrative expenses are a mixture of both fixed and variable expenses and include compensation, shipping and freight and marketing expenses. Selling and administrative expenses decreased (11.9%) to $23.8 million for the nine-months ended September 30, 2001 from $27.0 million for the comparable period in 2000. As a percentage of net sales, selling and administrative expenses increased to 24.5% for the nine-months ended September 30, 2001 from 23.2% for the comparable period in 2000, which was the result of the inability to reduce some fixed and semi-variable expenses associated with the decrease in net sales. The dollar decrease was primarily due to the following: o a decrease of ($1.3 million) in compensation and related employee benefits related to a reduction in employees including the resignation of various executives; o a decrease of ($600,000) in freight cost resulting from a decrease in net sales, which was partially offset by opening its Japan operations; o a decrease of ($1.1 million) in marketing related expenses, which was the result of not hosting various events for its Japan and United Kingdom operations; and o a decrease of ($200,000) in advertising expenses as a result of discontinuing operations of its Internet subsidiary. Other operating costs. Other operating costs include utilities, depreciation, travel, office expenses and printing expenses. Other operating costs decreased (28.0%) to $17.2 million for the nine-months ended September 30, 2001 from $23.9 million for the comparable period in 2000. As a percentage of net sales, other operating costs decreased to 17.7% for the nine-months ended September 30, 2001 from 20.6% for the comparable period in 2000. The percentage decrease was the result of management making a concerted effort to curtail expenses. The dollar decrease was primarily due to the following: o a decrease of ($2.0 million) related to variable expenses associated with a decrease in net sales and the curtailment of certain operating expenses; o a decrease of ($4.3 million) in expenses related to travel, consulting, postage and telephone expenses incurred in the prior year related to the expansion into the United Kingdom and Japan; o a decrease of ($200,000) from the prior year related to the buyout of Ray Robbins last remaining incentive agreement in 2000, which was initially canceled in July 1999; o a decrease of ($400,000) related to license fees paid to a third party for the Internet subsidiary, which discontinued operations on December 29, 2000, which was; o partially offset by an increase of $200,000 in depreciation expense related to the recent expansion into Japan. Severance expenses related to former executives. In the second quarter of 2001, management entered into Separation Agreements with various former executives and recorded a one-time charge of $3.4 million. The $3.4 million consisted of compensation related to the cancellation of their employment agreements, accrued vacation, health insurance and automobile expenses that will be paid to the former employees at various times through 2004. Write-off of a fixed asset. In the second quarter of 2000, Mannatech determined its Internet subsidiary, Internet Health Group, Inc.'s, fixed asset with a book value of $870,000 was impaired and should be written off. The write- off was a result of the continuation of the poor performance of the subsidiary, which discontinued operations as of December 29, 2000. Interest income. Interest income decreased (62.9%) to $208,000 for the nine-months ended September 30, 2001 from $561,000 for the comparable period in 2000. As a percentage of net sales, interest income decreased to 0.2% 14

for the nine-months ended September 30, 2001 from 0.5% for the comparable period in 2000. The decrease was due to using investments to fund current year operations. Interest expense. Interest expense decreased (59.3%) to $24,000 for the nine-months ended September 30, 2001 from $58,000 for the comparable period in 2000. As a percentage of net sales, interest expense decreased to 0.0% for the nine-months ended September 30, 2001 from (0.1%) for the comparable period in 2000. The decrease was primarily due to paying off an existing note and two capital leases. Other expense, net. Other expense, net consists of foreign currency translation adjustments related to the United Kingdom and Australia operations and miscellaneous non-operating items. Other expense, net decreased (65.5%) to ($132,000) for the nine-months ended September 30, 2001 from ($383,000) for the comparable period in 2000. As a percentage of net sales, other expense, net decreased to (0.2%) for the nine-months ended September 30, 2001 from (0.3%) for the comparable period in 2000. For the nine-months ended September 30, 2001, other expense, net consisted primarily of currency exchange losses due to currency translation fluctuations. For the nine-months ended September 30, 2000, other expense, net primarily consisted of approximately $36,000 in certain tax penalties and currency exchange losses due to currency translation fluctuations. Income tax (expense) benefit. Income tax benefit was $194,000 for the nine-months ended September 30, 2001 and $984,000 for the comparable period in 2000. Mannatech's effective tax rate decreased to 6.7% for the nine-months ended September 30, 2001 from 28.1% for the comparable period in 2000. Mannatech's effective tax rate decreased primarily as a result of Mannatech's inability to recognize foreign income tax benefits relative to its Japan operations. Cumulative effect of accounting change, net of tax. In the fourth quarter of 2000, Mannatech adopted SAB 101, which resulted in a one-time charge of $210,000, net of tax of $126,000 for the cumulative effect of the accounting change. SAB 101 required Mannatech to defer the recognition of revenues until the consumers receive their products shipped. Net loss. Net loss remained at ($2.7 million) for both the nine-months ended September 30, 2001 and the comparable period in 2000. As a percentage of net sales, the net loss slightly increased to (2.8%) for the nine-months ended September 30, 2001 from (2.4%) for the comparable period in 2000. In 2001, the net loss was primarily due to recording a one-time charge of $3.4 million related to the resignation of various executives who held employment agreements and a decrease in net sales of (16.5%), which was a direct result of a 26% decrease in active associates. This was partially offset by the curtailment of various operating expenses, no longer incurring expenses related to its Internet subsidiary and substantial completion of its planned international expansion into three foreign countries. For the nine-months ended September 30, 2001, Mannatech would have reported net income of $731,000, exclusive of the one-time severance charge for four former executives totaling $3.4 million. The net loss for 2000 primarily related to a decrease in net sales and incurring approximately $4.4 million in expenses related to its international expansion. Liquidity and Capital Resources Historically, Mannatech has funded its business objectives, working capital and operations through its cash flows from operations. Mannatech's working capital decreased to $5.8 million as of September 30, 2001 from $7.3 million at December 31, 2000. In 2000, Mannatech funded approximately $4.4 million for expansion into Japan and $4.1 million for operations for its Internet subsidiary, Internet Health Group, Inc. In 2001, Mannatech funded $2.1 million in payments to various former executives holding employment agreements, which totaled $3.4 million, and reported a decrease in net sales of 16.5%. Mannatech plans to continue to fund its business objectives, working capital and operations primarily through its current cash flows from operations. Provided by (used in) September 30, 2001 September 30, 2000 - --------------------- ------------------ ------------------ Operating activities $3.7 million ($860,000) Investing activities ($924,000) ($2.5 million) Financing activities ($2.7 million) ($715,000) Operating activities. For the nine-months ended September 30, 2000, operating activities primarily related to its international expansion into the United Kingdom and Japan, which resulted in a net loss of ($2.7 million) combined 15

with an increase in inventory of ($866,000), an increase in prepaids of ($390,000) and increase in receivables of ($1.4 million) for the expected income tax refund. These decreases were partially offset by $2.7 million in deprecation, the write-off of certain abandoned fixed assets of $423,000, and the impairment of a fixed asset from its Internet subsidiary totaling $870,000. For the nine-months ended September 30, 2001, operating activities primarily related to a one-time charge of $3.4 million related to the resignation of various executives, which resulted in a net loss of ($2.7 million), which was offset by recording $2.9 million in depreciation, a decrease in inventory of $3.0 million due to the closing of the Internet subsidiary, completion of its planned international expansion in 2000 and depleting its current on-hand inventory levels. Investing activities. For the nine-months ended September 30, 2000, investing activities consisted of purchases of computer hardware and software and the build out of the Japan facility totaling ($4.4 million), which was partially offset by the maturing of investments of $1.8 million. The investments were primarily used to fund current operations and opening its Japan subsidiary. For the nine-months ended September 30, 2001, investing activities consisted of purchases of property and equipment and software development costs totaling ($1.1 million) which were assets purchased for the new database primarily for its associates called Success Tracker, which was partially offset by the repayment of notes receivable due from a shareholder of $130,000. Financing activities. For the nine-months ended September 30, 2000, financing activities consisted of the repayment of various capital leases and notes payable totaling ($543,000), partially offset by the receipt of $328,000 related to the exercise of 235,700 stock options at prices per share ranging from $1.35 to $2.00. For the nine-months ended September 30, 2001, financing activities consisted of the payment of cash overdrafts of ($1.5 million), paying off two capital leases and a note payable of ($573,000) and the repurchase of 655,833 shares of common stock from Mr. Charles Fioretti totaling ($656,000) pursuant to his Lock-up and Repurchase Agreement, which was terminated on September 24, 2001. Mannatech believes its existing liquidity, capital resources and bank borrowings, coupled with the continuation of the suspension of dividend payments to shareholders should be adequate to fund its business operations and commitments for at least the next twelve months including the following: o In August 2001, Mannatech committed to fund up to $1 million to expand its core software database application onto a more easily maintainable architecture, which should provide additional reporting capabilities and scheduled to be substantially complete within the next twelve-months. o Funding payments totaling $2.7 million related to the recent resignations of Mr. Anthony Canale, Ms. Deanne Varner, Mr. Charles Fioretti and Mr. Patrick Cobb. Under the terms of the various separation agreements, Mannatech is required to pay an aggregate amount of $2.7 million, of which $1.6 million will be paid over the next twelve-months. o Funding payments of its annual insurance premiums, totaling approximately $1 million, which Mannatech has historically funded over ten monthly installments to various finance companies. Mannatech has no present commitments or agreements with respect to any acquisitions or purchases of any manufacturing facilities. Mannatech believes any future changes in its operations may consume available capital resources faster than anticipated. Mannatech believes its existing capital requirements depend on its retention and expansion of its current associate and member base and continuing to refine and introduce high-quality products. If existing capital resources or cash flows become insufficient to meet Mannatech's business plans and existing capital requirements, Mannatech would be required to raise additional funds, which it cannot assure will be available on favorable terms, if at all. Recent Financial Accounting Standards Board Statements In July 2001, the Financial Accounting Standards Board issued Statements of Financial Accounting Standards No. 141 ("SFAS 141") "Business Combinations" and No. 142 ("SFAS 142") "Goodwill and Other Intangibles Assets." 16

SFAS 141 supercedes Accounting Principles Board Opinion No. 16 "Business Combinations." The most significant changes made by SFAS 141 are that it requires that the purchase method of accounting be used for all business combinations initiated after June 30, 2001, establishes specific criteria for recognition of certain intangibles assets separately from goodwill and requires the immediate write-off of unallocated negative goodwill. SFAS 142 supercedes Accounting Principles Board Opinion No. 17 "Intangible Assets." SFAS 142 is effective for fiscal years beginning after December 15, 2001. SFAS 142 prohibits goodwill and indefinite lived intangible assets from being amortized and requires them to be annually tested for impairment at each reporting unit level. In addition, SFAS 142 removes the limitation of forty years for the useful lives of finite intangible assets. In June 2001, the Financial Accounting Standards Board issued Statements of Financial Accounting Standards No. 143 ("SFAS 143") "Accounting for Asset Retirement Obligations" and in October 2001, issued No. 144 ("SFAS 144") "Accounting for the Impairment or Disposal of Long-Lived Assets." SFAS 143 amends SFAS 19, "Financial Accounting and Reporting by Oil and Gas Producing Companies" and is effective for fiscal years beginning after June 15, 2002. This statement requires that the fair value of a liability for an asset retirement obligation be recognized in the period in which it is incurred if a reasonable estimate of fair value can be determined. In addition, SFAS 143 requires the associated asset retirement costs to be capitalized as part of the carrying amount of the long-lived asset. SFAS 144 supercedes SFAS No. 121 "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of" and Accounting Principles Board Opinion No. 30 "Reporting Results of Operations-Reporting the Effects of Disposal of a Segment of a Business." SFAS 144 is effective for fiscal years beginning after December 15, 2001. SFAS 144 requires that impaired long-lived assets be measured at the lower of carrying amount or fair value less costs to sell, regardless if they are reported in continuing operations or in discontinued operations. In addition, discontinued operations should no longer be measured at net realizable value or include amounts for operating losses that have not yet occurred. Finally, SFAS 144 broadens the reporting of discontinued operations to include all components of an entity with operations that can be distinguished from the rest of the entity and that will be eliminated from the ongoing operations of the entity in a disposal transaction. Mannatech believes the above pronouncements will have no significant effect on its consolidated financial positions, results of operations or cash flows. Outlook Mannatech believes its outlook for the remainder of 2001 and looking forward into 2002 will be contingent upon the success of retaining and expanding its active associate and member base, its ability to refine and introduce new high-quality products, which will expand sales to support its global operations and effectively communicate its changes to its compensation plan. Forward-Looking Statements Some of our statements under "Management's Discussion and Analysis of Financial Condition and Results of Operations," "Quantitative and Qualitative Disclosures about Market Risk" and Notes to Consolidated Financial Statements and elsewhere in this report may constitute "forward-looking statements" within the meaning of the Private Litigation Reform Act of 1995. Opinions, forecasts, projections, guidance or other statements other than statements of historical fact are considered forward-looking statements and reflect Mannatech's current views about future events and financial performance. These forward-looking statements are subject to certain events, risks and uncertainties that may be outside Mannatech's control. Some of these forward-looking statements include statements regarding: 17

o existing cash flows being adequate to fund its current business operations; o beliefs that some of its incentive plans will pay entry-level associates faster; o commissions not exceeding 42% of commissionable net sales; o the value of the United States dollar not materially effecting its overall financial results; o establishment of certain policy, procedures and internal processes to combat any exposure to market risk; o any actual impact of future market changes due to future exposure to currency rate fluctuations; o management's plans, objectives and budgets for its future operations and future economic performance; o capital budget and future capital requirements relating to capital projects and severance payments to executives; o maintaining current levels of future expenditures; o any significant impact on its financial positions, results of operations or cash flows by recent accounting pronouncements; o the outcome of any regulatory and litigation matters; o global statutory tax rates remaining unchanged; o the recent increase in its price of its stock; o Mannatech's products aiding in the overall health and wellness; and o the assumptions described in this report underlying such forward-looking statements. Actual results and developments may materially differ from those expressed in or implied by such statements due to a number of factors, including, without limitation: o those described in the context of such forward-looking statements; o future product development and manufacturing costs; o recent and future changes in Mannatech's global compensation and incentive plans; o retention and expansion of its associate and member base; o timely development and acceptance of new products or refinements of existing products; o the markets for Mannatech's domestic and international operations; o the impact of competitive products and pricing; o the political, social and economic climate in which Mannatech conducts its operations; and o the risk factors described in other documents and reports filed with the Securities and Exchange Commission. 18

In some cases, forward-looking statements are identified by terminology such as "may," "will," "should," "could," "expects," "plans," "intends," "anticipates," "believes," "estimates," "approximates," "predicts," "potential," "in the future" or "continue" or the negative of such terms and other comparable terminology. Readers are cautioned when considering these forward-looking statements to keep in mind these risks and uncertainties and any other cautionary statements in this report as all of the forward-looking statements contained herein speak only as of the date of this report. Item 3. Quantitative and Qualitative Disclosures About Market Risk Mannatech does not engage in trading market risk sensitive instruments and does not purchase investments and hedges for purposes "other than trading," that are likely to expose it to certain types of market risk, including interest rate, commodity price or equity price risk. Mannatech has investments, but there has been no material change in its exposure to interest rate risk. 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 when the exchange rate weakens against currencies in which Mannatech incurs costs, net sales or costs may be adversely affected. Mannatech has established certain policies, procedures and internal processes, which it believes will help monitor any significant market risks. Currently, Mannatech does not use any financial instruments to manage its exposure to such risks. The sensitivity of earnings and cash flows to variability in currency exchange rates 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 September 30, 2001, Mannatech believes the actual impact of future market changes could differ materially due to, among other things, factors discussed in this report. Mannatech cannot predict with any certainty its future exposure to such currency exchange rate fluctuations or the impact, if any, it may have on its future business, product pricing, consolidated financial position, results of operations or cash flows; however, Mannatech believes it closely monitors current fluctuations for exposure to such market risk. Currently, 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 currency exchange rates to the United States dollar, for each of these countries, for the nine-months ended September 30, 2001 are as follows: Country/Currency High Low - ---------------- -------- -------- Australia/Dollar ................ $0.57220 $0.47730 United Kingdom/British Pound .... $1.51030 $1.36770 Japan/Yen ....................... $0.00880 $0.00788 PART II - OTHER INFORMATION Item 1. Legal Proceedings There have been no material changes in, or additions to, the legal proceedings previously reported in Mannatech's Annual Report on Form 10-K as amended (File No. 000-24657) for 2000 as filed with the Securities and Exchange Commission on April 2, 2001. Item 2. Changes in Securities and Use of Proceeds On September 28, 2001, Mannatech entered into an agreement with Mr. Ray Robbins, a high-level associate, shareholder and board member, to sell to him all of Mannatech's 815,009 shares of treasury stock at $1.00 per share. 19

Item 3. Defaults Upon Senior Securities Not applicable. Item 4. Submission of Matters to a Vote of Security Holders None. Item 5. Other Information On October 1, 2001, the Board of Directors appointed Mr. J. Stanley Fredrick to the Board of Directors to replace Mr. Charles Fioretti, who resigned from the Board of Directors in August 2001. Mr. Fredrick has considerable industry experience with various companies engaged in direct selling activities. Mr. Fredrick has served as the President and CEO of SMC Industries, which included Saladmaster Corporation among its holdings, and was co-founder, Chairman and CEO of Cameo Couture, which sold products through home parties.

Under the terms of the agreement, Mannatech will pay Mr. Fredrick $185,000 annually. The Consulting and Lockup Agreement automatically renews annually unless terminated by either party.

EXHIBIT 10.1 AGREEMENT This non-exclusive Consultancy and Lock-Up Agreement ("Agreement") is made and effective this 1st day of october 2001, by and between Mannatech, Incorporated ("Company"), a Texas corporation with its principal place of business located at 600 S.

ARTICLE I. DUTIES AND COMPENSATION 1.1 Term. The term of this Agreement, unless otherwise modified in writing, is for a two (2) year calendar period, beginning September 30, 2001 and ending September 30, 2003 (the "Term").

ARTICLE II LOCK-UP AGREEMENT 2.1 Lock-Up Period. Except as contemplated in this Agreement, Consultant hereby agrees during the term of this Consultancy Agreement (the "Lock-Up Period"), he will not offer, sell, assign, pledge, transfer, hypothecate, contract to sell, grant any option for the sale of or otherwise dispose of, directly or indirectly, and except to a family member or family controlled trust, upon prior written notification to the Company, any of the Common Stock or securities convertible into or exchangeable or exercisable for any shares of Common Stock, enter into a transaction which would have the same effect, or enter into any swap, hedge or other arrangement that transfers, in whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such aforementioned transaction is to be settled by delivery of the Common Stock or such other securities, in cash or otherwise, or publicly disclose the intention to make any such offer, sale, pledge or disposition, or to enter into any such transaction, swap, hedge or other arrangement, without, in each case, the prior written consent of Company. Any securities received upon exercise of options granted to Consultant will also be subject to the provisions set forth in this Article II. Consultant agrees and consents to the entry and stop transfer instructions with Company's transfer agent against any transfer of shares of Common Stock held directly or indirectly by Consultant not in compliance with this Agreement. 2.2. Extended Lock-Up. The restrictions and obligations of Consultant under Section 2.1 shall be extended without any further action (the "Extended Lock-Up Period") in the event the Consultancy Agreement is extended pursuant to the terms of Section 1.1 hereof. The Lock-Up shall be extended so long as the Company continues to pay the Consultant in accordance with Section 1.2 hereof or until the Company makes a secondary offering of its common stock. ARTICLE III. NON-COMPETITION and NON-SOLICITATION 3.1 Non-Competition. To the full extent permitted by law, the Consultant will not for a period of one (1) year following the termination of this Agreement: 3.1.1 Attempt to cause any person, firm or corporation, which is a customer of or has a contractual relationship with Company (including its Associates) at the time of termination of this Agreement to terminate such relationship with Company. This provision shall apply regardless of whether such customer has a valid contractual arrangement with Company; 3.1.2 Attempt to cause any employee of Company to leave such employment; 3.1.3 Engage any person who was an employee of Company at the time of the termination of this Agreement or cause such person otherwise to become associated with the Consultant or with any other person, corporation, partnership or other entity with which the Consultant may thereafter become associated; or 4

3.1.4 Engage in any activity or perform any services competitive with any business conducted by Company, and in any country in which Company operates, at the time of execution of this Agreement other than duties that occur under the course of his current business in which he participates, of which he has fully disclosed to the Company, as indicated and attached hereto as Exhibit "B", upon the execution of this Agreement. As set forth above, the Consultant acknowledges that the foregoing non-competition and non-solicitation covenants are ancillary to or a part of an otherwise enforceable agreement, such being the general agreement of this Consultancy and its related agreements concerning confidentiality and non-disclosure of Confidential Information and non-solicitation. The Consultant acknowledges that at the time that this non-competition covenant is made, that the limitations as to time defined herein and that the limitations as to geographic area are reasonable and do not impose a greater restraint than is necessary to protect the goodwill or other business interests of Company. 3.2 Consultant agrees that in the highly competitive business in which Company is engaged, personal contact is of primary importance in securing new and retaining present Associates and customers. The Consultant also agrees that Company 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 Company's Associates and customers in relation to the Company's current business and exploit the personal relationships that he develops with Company's Associates and customers by virtue of his access to them as a result of this Consultancy. 3.3 Consultant shall be bound by and abide by all reasonable policies and procedures of Company that are within the scope of his Consultancy and that are in effect during the term of his Consultancy. 3.4 Consultant acknowledges and agrees that he owes a fiduciary duty of loyalty, fidelity, and allegiance to act at all times in the best interests of Company. In keeping with these duties, Consultant shall make full disclosure to Company of all business opportunities pertaining to Company's present business and shall not appropriate for Consultant's own benefit business opportunities concerning such business. 3.5 The Parties agree that during the term of this Agreement and thereafter, they will not disparage each other or their respective Affiliates. 3.6 Irrespective of the term of this Agreement, and in consideration of the promises specified in Article II of this Agreement, Company agrees as follows: 3.6.1 To provide specialized training as specified herein; and 3.6.2 To provide the Consultant with access to Company'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, as defined in Article III hereof, which is regularly used in the operation of the business of Company. 5

3.7 Nothing contained herein shall prevent the Consultant from undertaking or continuing business interests and endeavors that do not directly relate to the Company's present business, that he has upon execution hereof and/or making financial investments as he sees fit. ARTICLE IV.

EXHIBIT 10.4 September 10, 2001 JETT 59-340 Olahama Road Kamuela, Hawaii 96743 RE: Follow-Up Agreement to Letter of Intent dated July 12, 2001 Dear Jett: This letter shall set forth our understanding going forward concerning the Letter Agreement submitted to you dated November 1, 1999 and the above-referenced Letter of Intent pertaining to the payment obligation of $2.8 million, as indicated and attached hereto as Exhibits "A" and "B", respectively and both of which are fully integrated and incorporated by reference herein. As of September 1, 2001, Mannatech will have paid to you the final monthly payment of $50,000 for a total of $1.2 million. Mannatech has agreed to pay to you the balance of $1.6 million ("Balance") through royalty payments on two audiotapes, the content of which will be comprised of material that has been reviewed by Mannatech legal counsel to ensure compliance with all governmental laws, rules and regulations in each of the countries in which the audiotapes are contemplated to be sold (both tapes shall hereinafter be referred to as the "Tape"). The audiotapes shall be in two formats, one such format to be included in Associate Business Packs and the other in Associate Consumer/Product Packs. You agree to fully cooperate with Mannatech's SeniorVice President of Marketing (or his designee) in the development and any subsequent revisions of this Tape, as may be required from time-to-time. The Tape will be included in each Associate Sign-up kit ("Kit") and the equivalent in each country of operation in which the Tape is included in the Kits). Mannatech shall pay to you a royalty of $5.00 for each Kit sold (of which the Tape is included) until such time as the Balance is paid in full. On a monthly basis, commencing on the month following inclusion of the Tape, Mannatech shall compute the total royalties earned by you and, on making that determination, shall remit promptly the royalty payment and a copy of the royalty statement thirty (30) days after the computation date and on the same date at the end of each month throughout the term of this Agreement, to you or your appointed agent. If you, for any reason, object to any royalty statement submitted by Mannatech, you shall set forth the objection in writing and submit it to the Chief Financial Officer within thirty (30) days from the date of the statement. Any objection you may have to any royalty statement shall be deemed waived unless it is transmitted in accordance with the terms of this paragraph. Royalties will not be paid on those Tapes retained by Mannatech for promotional or internal usage. Mannatech has previously reviewed and approved materials that you have produced for sale through third-party vendors. Mannatech will likewise afford to you the opportunity to sell the following promotional materials through its Internet storefront, the sales price, royalties and proceeds of which to be determined at a later date and governed by a separate written agreement, but in any event, the agreed proceeds from those Internet storefront sales shall be applied against the Balance: Jett's Millionaire University (MT approval Number: MT99004A) Jett's Millionaire University Handbook (MT approval Number: MT99004B) 1

(collectively, "Pre-Approved Materials"). Mannatech will likewise consider inclusion of other promotional sales materials that you have produced, pending review and approval of the content in accordance with Mannatech's current policies and procedures pertaining to third-party vendors and production of promotional materials. Notwithstanding the foregoing, the provisions of this paragraph shall not apply if sales of MT99004A and MT99004B should cause you to breach any prior agreement you may have with a third-party for sales of the same. Mannatech will continue to support your efforts to build a Mannatech business in Japan and will reimburse you for reasonable expenses incurred subject to the following criteria: a. Trips to Japan should be pre-approved by the President of International Operations or the Chief Executive Officer; b. Expense reimbursement will include round trip business class airfare plus meals and lodging expenses, not to exceed $ 250.00 per day; c. All expenses must be documented and submitted for reimbursement within a reasonable period of time after trips are completed; and d. Expense reimbursement as contemplated in this paragraph shall cease on December 31, 2001. Mannatech shall use its best efforts to arrange a convenient time and location for the production of the Tape as outlined herein. The Parties agree that time is of the essence as to the production of the Tape and in any event, the Tape must be produced for inclusion in the Kits during the first quarter of fiscal year 2002. The Parties agree to fully cooperate in good faith to ensure the content of the tape is mutually agreeable as outlined herein. We expect and you agree that the respective tradename(s), trademarks, copyrights, marketing plans, identity and related information regarding Associates and any information relating to the management/operations of Mannatech ("Confidential Information") is the sole property and trade secret of Mannatech. The Confidential Information shall not be used, sold, disclosed or assigned by you for any purpose. Upon termination of this Agreement, you agree to return to Mannatech all written materials, software, customer/member/representative lists and other information that contains Confidential Information and you further agree not to use such Confidential Information. You agree that Mannatech will suffer irreparable harm in the event its Confidential Information is disclosed to third-parties for which damages would be inadequate. In the event of breach or threatened breach of this Section, Mannatech will be entitled to an injunction restraining you from disclosing, in whole or in part, any Confidential Information to any person, firm, Company, association or other entity to whom Mannatech's Confidential Information, in whole or in part, has been disclosed or threatened to be disclosed. Nothing contained herein will be construed as limiting Mannatech from, or prohibiting Mannatech from, pursuing any other remedies available to it for such breach, or threatened breach, including recovery of damages. This section shall survive the termination of this agreement. While you are associated with Mannatech or any of its subsidiaries and for a period of one year thereafter ("One Year Period") or a shorter period with the written consent of Mannatech), after you shall cease to be associated with Mannatech for any reason, you agree not to, directly or indirectly, own an interest in, operate, join, control or participate in, or be connected as an officer, employee, agent, independent contractor, partner, shareholder, or principal of any corporation, partnership, proprietorship, firm, association, person or other entity producing, designing, providing, soliciting orders for, selling, distributing, or marketing products, goods, equipment, or services of any other multi-level marketing or direct selling company any 2

country in which Mannatech conducts business, nor shall you develop any products or goods during such One Year Period which compete with the goods and products of Mannatech You agree that 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 judgment of a court of competent jurisdiction, as the case may be, may define the maximum territory and actions subject thereto and restricted by this provision and the period of time during which the Agreement is enforceable. Any alleged breach of other provisions of this Agreement asserted by you shall not be a defense for you to claims arising from Mannatech's enforcement of the provisions of this paragraph or alternatively, that you have agreed to the broadest restrictive covenants against competition by you with Mannatech during the One Year Period, as may construed by a court of competent jurisdiction. Should you violate the non-competition provision, then the period of time for these covenants shall automatically be extended for the period of time from which you began such violation until you permanently cease such violation. Mannatech expects and you further agree that once the Balance has been paid in full or in the event that you breach any provision herein for any reason whatsoever, Mannatech's payment obligations as described hereunder shall automatically cease and Mannatech shall be under no obligation to continue to include the Tape and/or offer for sale any of the Pre-approved Materials as contemplated hereby. This Letter Agreement embodies and constitutes the entire understanding between Mannatech and yourself with respect to the transactions contemplated herein, and all prior or contemporaneous agreements, understandings, representations and statements (oral or written) of any nature whatsoever, including agreements for additional compensation, benefits and stock are fully integrated and merged into this Letter Agreement. The foregoing notwithstanding, nothing in this Letter Agreement shall be deemed to alter or amend the obligations created under any Associate Agreement, which creates an Associate position in the Mannatech downline of which you are a party. You agree that this Agreement is entered in and under the laws of the State of Texas and is to be enforced and shall be interpreted under the laws of the State of Texas. You further agree that any dispute concerning this Agreement, the obligations or alleged breach of this Agreement, and any other claim, dispute or other difference which may arise between Mannatech and yourself regarding this Agreement shall be resolved exclusively by binding arbitration pursuant to the Commercial Arbitration Rules of the American Arbitration Association, which arbitration, if necessary, shall be in Dallas, Texas. You further agree that exclusive jurisdiction and venue to enforce the arbitration provisions of this agreement shall be in a state or federal court of appropriate jurisdiction in Dallas County, Texas. You additionally consent to personal jurisdiction in Dallas County, Texas, for any action to enforce arbitration including any further rules provided for emergency or extraordinary relief, as to this Letter Agreement. From time-to-time, as our relationship evolves, we may reach other requirements, undertakings or provisions which require additional documentation, and which may either supplement or amend this letter. Such supplements and amendments shall be binding Mannatech and you only to the extent that they are included in a writing signed by both parties. 3

The offer as set forth herein shall expire and be automatically revoked and cancelled unless Mannatech received an executed original of this Agreement on or before 5:00 p.m. CST, September 25, 2001.
