                               PROSPECTUS SUMMARY
 
    THE FOLLOWING SUMMARY IS QUALIFIED IN ITS ENTIRETY BY THE MORE DETAILED
INFORMATION AND THE FINANCIAL STATEMENTS AND NOTES THERETO APPEARING ELSEWHERE
IN THIS PROSPECTUS. INVESTORS SHOULD CAREFULLY CONSIDER THE RISK FACTORS RELATED
TO THE PURCHASE OF COMMON STOCK OF THE COMPANY. UNLESS OTHERWISE INDICATED, ALL
INFORMATION IN THIS PROSPECTUS REFLECTS A 1,000-FOR-1 SPLIT OF THE COMPANY'S
OUTSTANDING COMMON STOCK EFFECTED IN 1997 (THE "STOCK SPLIT"). SEE "RISK
FACTORS."
 
                                  THE COMPANY
 
   
    Mannatech develops and sells proprietary nutritional supplements and topical
products through a network marketing system. The Company sells its products in
the United States and Canada, through a network consisting of approximately
226,000 active Associates (an "active" Associate has purchased products from the
Company within the last 12 months) as of September 30, 1998, and is currently
planning to expand into Australia, while continuing to assess the potential of
other foreign markets. Since commencing operations in November 1993, the
Company's sales have grown from approximately $8.4 million in 1994 to
approximately $150.6 million in 1997.
    
 
    The Company pursues a two-fold business strategy: (i) to develop a
proprietary line of nutritional supplements having both health benefits and mass
appeal to a general population demanding non-toxic healthcare alternatives and
(ii) to provide an appealing framework for persons interested in the products to
establish a direct sales business. To date, the Company has focused its
development efforts primarily in the area of carbohydrate technology, creating a
proprietary ingredient, Ambrotose-Registered Trademark- Complex, which combines
the naturally occurring sugars required to support optimal cell-to-cell
communication. Additional Company efforts have been focused on developing
products based on scientific advances in the emerging field of phytochemistry,
which has identified certain naturally occurring components of various plants,
known as "phytochemicals," which, while not essential to sustain life, are
fundamental to optimal health.
 
    Ambrotose-Registered Trademark- Complex is the cornerstone of the Company's
product lines. These products are designed to support various systems and
functions of the human body, including (i) the cell-to-cell communication
system, (ii) the immune system, (iii) the endocrine system, (iv) the intestinal
system and (v) the dermal system. The Company also markets products designed to
aid in sports performance and nutritional support. The Company's products,
Man-Aloe-Registered Trademark-, Ambrotose-Registered Trademark- and Bulk
Ambrotose-Registered Trademark-, are designed to support cell-to-cell
communication. For immune system support, the Company offers
Phyt-Aloe-Registered Trademark-, for adults, and Phyto-Bears-Registered
Trademark-, a chewable gummi-bear nutritional supplement product marketed to
children but popular with adults. Other products include MVP-TM- and Plus for
endocrine system support, MannaCleanse-TM- for intestinal system support and
Emprizone-Registered Trademark-, Firm and Naturalizer for dermal care. The
Company offers several products designed to aid sports performance by enhancing
the body's natural recovery process and supporting lean tissue development,
including Em-Pact-TM-, Bulk Em-Pact-TM- and Sport with Ambrotose-Registered
Trademark-. The Company also markets Profile 1, Profile 2 and Profile 3, which
support the body's nutritional needs.
 
   
    In March 1998, the Company introduced MannaBAR-TM-, a nutritional supplement
bar in two versions that contain the equivalent of the Company's recommended
minimum daily supply of Ambrotose-Registered Trademark-Complex,
Phyt-Aloe-Registered Trademark- and Plus. In September 1998 the Company
introduced Manna-C-TM-, a nutritional support for nasal and sinus health
containing Ambrotose-Registered Trademark- Complex, monosaccharides necessary to
the manufacture of glycoproteins and an herbal blend of Vitamin C and other
nutrients which support cell functions and, in October 1998, introduced
Ambrostart, a nutritional support fiberdrink containing Ambrotose-Registered
Trademark- Complex, and Bulk Phyt-Aloe-Registered Trademark-. In addition to
MannaBAR-TM- and Manna-C-TM-, the Company plans to release additional products
as new nutritional compounds or areas of consumer demand are identified by the
Company. All new products are expected to contain proprietary components.
    
 
                                       2
<PAGE>
    The Company's products are marketed exclusively through a network marketing
system. The Company believes that its network marketing system is well-suited to
its products, which emphasize health and nutrition, because network marketing
allows in-person product education not available through traditional marketing
techniques. The Company's network marketing system appeals to a broad cross-
section of people, particularly those seeking to supplement family income, start
a home-based business or pursue employment opportunities other than
conventional, full-time employment.
 
    In 1997, the Company made a substantial investment in infrastructure,
including investments in its new headquarters building, new distribution center,
information technology systems and new research and development laboratory. The
Company believes it will be able to continue its sustained and profitable growth
by capitalizing on its operating strengths, including its (i) proprietary
product offerings, (ii) superior research and development capability, (iii)
strong Associate support philosophy, (iv) flexible operating strategy and (v)
experienced management team.
 
    Prior to June 1, 1997, certain of the Company's intellectual property rights
and marketing rights were held by limited partnerships controlled by certain of
the Company's shareholders. On June 1, 1997, in order to simplify the Company's
ownership structure and consolidate all operating activities, the Company
entered into agreements to effect a reorganization through merging with the
corporate general partners of the limited partnerships in which the Company was
the surviving corporation and exchanging shares of Common Stock for the entire
ownership interests of the limited partnerships (the "Reorganization"). Pursuant
to the Reorganization, the Company issued an aggregate of 10,000,000 shares of
Common Stock to the holders of the general partnership and the limited
partnership interests. In addition, during May and June 1997 the Company issued
2,027,571 shares of Common Stock in consideration for the cancellation of
incentive compensation agreements with two shareholder-employees and four other
employees of the Company, including 626,971 shares issued to cancel incentive
compensation agreements that had been provided in lieu of ownership interests in
the limited partnerships. See Note 9 to the Financial Statements. The net effect
of the foregoing transactions was to increase the number of shares of Common
Stock outstanding by 12,027,571, while retaining substantially the same relative
ownership of the Company among the Company's original shareholders. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations," "Certain Transactions-Partnership Transactions" and "-Incentive
Compensation Agreements."
 
    The Company was incorporated in Texas in 1993 under the name Emprise
International, Inc. and changed its name to Mannatech, Incorporated in 1995. The
principal executive offices of the Company are located at 600 S. Royal Lane,
Suite 200, Coppell, Texas 75019, and the Company's telephone number is (972)
471-7400.

- ------------------------------
 
(1) Statement of Income Data for the year ended December 31, 1994 includes the
    period from November 4, 1993 (inception) through December 31, 1994. For the
    two months of operations ended December 31, 1993, the Company's financial
    data consisted of net sales of $0, selling and administrative expenses of
    $43,049, other operating costs of $68,683 and a net loss of ($112,733). The
    balance sheet reflects a total shareholders' deficit of ($111,733).
 
(2) In June 1997 and December 1997, the Company recorded one-time charges to
    operations for the issuance of stock in exchange for the cancellation of
    certain incentive compensation agreements. See "Management's Discussion and
    Analysis of Financial Condition and Results of Operations" and "Certain
    Transactions."
 
(3) Computed on the basis described in Note 1 in the Notes to Financial
    Statements.
 
(4) The pro forma information shows the Company's net income and earnings per
    share as if all income earned by the Company and the limited partnerships
    was taxable at federal and state statutory rates.
 
   
(5) Capital expenditures include assets acquired through capital lease
    obligations of $397,402 in 1997 and $1,471,985 for the nine months ended

(6) Dividends were calculated based upon shares outstanding prior to the Stock
    Split and the Reorganization (10,000 shares), each of which took place in
    1997. Aggregate dividends declared amounted to $10,000, $10,000 and $100,000
    in 1994, 1995 and 1996, respectively.

    See "Use of Proceeds" and "Capitalization." In addition, as of September 30,
    1998, the Company had recorded $1,500,000 of deferred offering cost relating
    to this offering. Total assets and shareholders' equity have been reduced by
    this amount as well.

                                  RISK FACTORS
 
    THE FOLLOWING RISK FACTORS SHOULD BE CONSIDERED CAREFULLY IN ADDITION TO THE
OTHER INFORMATION IN THIS PROSPECTUS BEFORE PURCHASING THE COMMON STOCK OFFERED
BY THIS PROSPECTUS. EXCEPT FOR THE HISTORICAL INFORMATION CONTAINED HEREIN, THE
DISCUSSION IN THIS PROSPECTUS CONTAINS CERTAIN FORWARD-LOOKING STATEMENTS THAT
INVOLVE RISKS AND UNCERTAINTIES. WHEN USED IN THIS PROSPECTUS, THE WORDS
"BELIEVES," "EXPECTS," "ANTICIPATES," "INTENDS," "ESTIMATES," "SHOULD," "WILL
LIKELY," "PLANS TO" AND SIMILAR EXPRESSIONS ARE INTENDED TO IDENTIFY SUCH
FORWARD-LOOKING STATEMENTS. THE CAUTIONARY STATEMENTS MADE IN THIS PROSPECTUS
SHOULD BE READ AS BEING APPLICABLE TO ALL RELATED FORWARD-LOOKING STATEMENTS
WHEREVER THEY APPEAR IN THIS PROSPECTUS. THE COMPANY'S ACTUAL RESULTS COULD
DIFFER MATERIALLY FROM THOSE DISCUSSED HEREIN. IMPORTANT FACTORS THAT COULD
CAUSE OR CONTRIBUTE TO SUCH DIFFERENCES INCLUDE THOSE DISCUSSED BELOW, AS WELL
AS THOSE DISCUSSED ELSEWHERE HEREIN.
 
   
    BEST EFFORTS OFFERING; MINIMUM NUMBER OF SHARES TO BE SOLD.  The Company is
offering its Common Stock on a "best efforts" basis. There can be no assurance
that all of the 2,200,000 shares of Common Stock offered by the Company hereby
will be sold and that the estimated net proceeds generated from such a sale of
all such Common Stock will actually be received by the Company. If the Company
is unable to sell at least 2,500,000 shares of the Common Stock offered hereby,
the Company will cancel this offering and return all monies collected from
subscribers and held in escrow without interest or deduction. Furthermore, if
all of the 2,200,000 shares of Common Stock offered by the Company hereby are
not sold, the Company may be unable to fund all the intended uses described
herein for the net proceeds anticipated from this offering without obtaining
funds from alternative sources or using working capital generated by the
Company. Alternative sources of funds may not be available to the Company at a
reasonable cost, and the working capital generated by the Company may not be
sufficient to fund any uses not financed by offering proceeds. See "Use of
Proceeds," "Management's Discussion and Analysis of Financial Condition and
Results of Operations-Liquidity and Capital Resources" and "Plan of
Distribution."
    
 
   
    RELATIONSHIP OF OFFERING PRICE TO MARKET PRICE.  The initial public offering
price of the Common Stock has been arbitrarily determined by the Company and may
not be indicative of the price at which shares of Common Stock will sell after
this offering or its value, in general. In determining the offering price, the
Board of Directors of the Company (the "Board of Directors") considered, among
other things, the Company's earnings, its view of the Company's prospects, the
earnings of comparable publicly traded nutritional supplement companies and the
trading price of the stock of those companies. See "Plan of
Distribution--Determination of Offering Price." The Company makes no
representations as to any objectively reasonable value of the Common Stock.
Since the Company has not retained an underwriter for purposes of this offering,
the offering price has not been subject to evaluation by any third party as
would be the case in an underwritten offering. Prices for the shares of Common
Stock after this offering will be determined in the available market and may be
influenced by many factors, including the depth and liquidity of the market for
the Common Stock, the perception of the Company by other investors, the
nutritional supplement industry as a whole, and general economic and market
conditions.
    
 
   
    NO PRIOR MARKET FOR COMMON STOCK; PRICE VOLATILITY.  Prior to this offering,
there has been no public market for the Common Stock, and there can be no
assurance that an active trading market will develop subsequent to this offering
or, if developed, that it will be sustained. Upon completion of this offering,
it is expected that the Common Stock will be quoted on the Nasdaq National
Market, which has experienced and is likely to experience in the future
significant price and volume fluctuations which could adversely affect the
market price of the Common Stock without regard to the operating performance of
the Company. Broad market fluctuations, as well as general economic conditions,
in the United States or internationally, may adversely affect the market price
of the Common Stock. In addition, the Company believes that factors such as
quarterly fluctuations in the financial results of the Company, the Company's
earnings, changes in earnings estimates by analysts, financial and business
announcements by the Company or its competitors, the overall economy and the
condition of the financial markets could cause the market price of the Common
Stock to fluctuate substantially. There can be no assurance that the market
price of the Common Stock will not decline below the initial public offering
price. See "Plan of
    
 
                                       7

Distribution" and "Management's Discussion and Analysis of Results of Operations
and Financial Condition."
 
    RISKS ASSOCIATED WITH INTERNATIONAL EXPANSION.  An element of the Company's
growth strategy is to initiate the distribution and sale of the Company's
products in international markets. The Company may experience difficulty
entering new international markets due to greater regulatory barriers, the
necessity of adapting to new regulatory systems and problems related to entering
new markets with different cultural bases and political systems. The Company's
planned international operations will be subject to political and economic
uncertainties, including, among others, inflation, risk of renegotiation or
modification of existing agreements or arrangements with governmental
authorities, transportation, tariffs, export control, government regulation,
trademark availability and registration issues, currency exchange rate
fluctuations, foreign exchange restrictions which limit the repatriation of
investments and earnings therefrom, changes in taxation, hostilities or
confiscation of property. Changes related to these matters could have a material
adverse effect on the Company's business, results of operations and financial
condition. No assurance can be given that the Company will be able to
successfully reformulate its product lines in any of the Company's potential new
markets to attract local consumers or to meet regulatory requirements. The
failure to do so would have a material adverse effect on the Company's business,
results of operations and financial condition. See "Business-Growth Strategy."
 
   
    SHARES ELIGIBLE FOR FUTURE SALE.  Sales of a substantial number of shares of
Common Stock in the public market following this offering could adversely affect
the market price for the Common Stock. Upon completion of this offering, there
is expected to be a minimum of 23,618,769 shares and a maximum of 24,776,753
shares of Common Stock outstanding. All of the shares offered hereby will be
freely tradeable without restriction or further registration under the
Securities Act of 1933, as amended (the "Securities Act"), unless purchased by
"affiliates" of the Company, as that term is defined in Rule 144 under the
Securities Act ("Rule 144") described below. The remaining 21,118,769 shares or
19,481,738 shares, respectively, of Common Stock outstanding upon completion of
this offering are "restricted securities," as that term is defined in Rule 144
(the "Restricted Shares"). Of the Restricted Shares, 20,999,602 shares or
19,362,571 shares, respectively, will be eligible for sale in the open market
after the effective date of the Registration Statement, all under and subject to
the restrictions contained in Rule 144 and Rule 701.
    
 
   
    Prior to the completion of this offering, the Company intends to enter into
lock-up agreements (the "Lock-up Agreements") with each of the Company's
shareholders and holders of options to purchase Common Stock. Pursuant to the
Lock-up Agreements, each such shareholder will agree, subject to certain
exceptions, not to sell or otherwise dispose of any of its shares of Common
Stock until 180 days after the completion of this offering (the "Lock-up
Expiration Date").
    
 
   
    Under the Company's 1997 Stock Option Plan (the "1997 Stock Option Plan"),
as of September 30, 1998 options to purchase 2,000,000 shares of Common Stock
were outstanding, 1,600,000 of which will become exercisable 90 days after the
effective date of this Prospectus and 400,000 of which will be exercisable on
July 31, 1999, assuming completion of this offering. No shares remained
available for future grants to employees and consultants of the Company under
the 1997 Stock Option Plan. Under the Company's 1998 Incentive Stock Option Plan
(the "1998 Stock Option Plan"), as of September 30, 1998 options to purchase
243,000 shares of Common Stock were outstanding, all of which will become
exercisable on July 31, 1999, assuming completion of this offering. An
additional 757,000 remained available for future option grants. The Company
intends to register on Form S-8 under the Securities Act the offering and sale
of Common Stock issuable under the 1997 Stock Option Plan and the 1998 Stock
Option Plan as soon as practicable after the date of this Prospectus.
    
 
   
    As of September 30, 1998, an additional 100,000 shares of Common Stock were
issuable upon the exercise of an outstanding option (the "Non-Plan Option") at
an exercise price of $2.00 per share, which will become exercisable 90 days
after the effective date of this Prospectus. In addition, as of September 30,
1998, a warrant (the "Warrant") to purchase 475,015 shares of Common Stock was
outstanding, which is currently exercisable and of which a maximum of 475,015
shares may be sold in this offering. The holder of the Warrant possesses
registration rights with respect to the shares of Common Stock
    
 
                                       8

underlying the Warrant. Sales of shares of Common Stock under either Rule 144 or
pursuant to a registration statement could have a material adverse effect on the
price of the Common Stock. See "Management-Stock Option Plans," "Description of
Capital Stock-Warrant Shares" and "Shares Eligible for Future Sale."
 
    RELIANCE UPON ASSOCIATES.  The Company distributes its products exclusively
through its Associates, and the Company's success depends in significant part
upon its ability to attract, maintain and motivate a large base of Associates,
who, in turn, recruit additional Associates to purchase and sell the Company's
products. Significant turnover among Associates from year to year, which the
Company believes is typical of direct selling, requires the sponsoring of new
Associates by existing Associates in order to maintain or increase the overall
Associate force. Efforts by Associates to obtain new Associates are affected by
the level of Associate motivation, which in turn can be positively or negatively
affected by certain factors, including general economic conditions,
modifications in the amount of commissions paid, and public perception of the
quality of the Company's products. For 1997, the Company's commission expense
comprised approximately 56% of its total expenses exclusive of cost of sales and
income taxes. The Company's ability to attract and retain new Associates could
be negatively affected by adverse publicity relating to the Company or its
services or its operations, including its network marketing system. Because of
the number of factors that impact the recruiting of Associates, the Company
cannot predict when or to what extent increases or decreases in the level of
Associate retention will occur. In addition, the number of Associates as a
percentage of the population may reach levels that become difficult to exceed
due to the finite number of persons inclined to pursue direct selling as a
business. There can be no assurance that the number or productivity of
Associates will be sustained at current levels or will increase in the future.
The failure of the Company to attract and retain Associates in sufficient
numbers would have a material adverse effect on the Company's business, results
of operations and financial condition. Furthermore, the Company's business,
results of operations and financial condition could be materially adversely
affected if the Company finds it necessary to terminate a significant number of
Associates or certain Associates who play a key role in the Company's
distribution system. See "Business-Growth Strategy" and "-Product Distribution
System."
 
    REGULATION AND MANAGEMENT OF ASSOCIATES.  Associates are independent
contractors, not employees of the Company, and are not subject to the same level
of direction and oversight as Company employees. While the Company has policies
and rules in place governing the conduct of Associates, as well as a systematic
method of monitoring, compliance enforcement and discipline, it is difficult to
detect and correct all instances of Associate misconduct. The Company's efforts
to manage its Associates can result in litigation from time to time between the
Company and its Associates and an adverse outcome in such litigation could
adversely affect the Company's business, results of operations and financial
condition. See "Business-Legal Proceedings." Violations of these policies and
rules reflect negatively on the Company and could also lead to formal or
informal complaints by various federal, state or foreign regulatory authorities.
In addition, formal and informal complaints regarding Associate conduct issues
are occasionally filed with state attorneys general offices. These offices have,
from time-to-time, contacted the Company and, in two instances, have met with
representatives of the Company to review the activities of the Company and its
Associates in their respective jurisdictions. Complaints or enforcement actions
by federal, state or foreign regulatory authorities may occur in the future and
could have a material adverse effect on the Company's business, results of
operations and financial condition. If the Company enters new international
markets, the challenge of coordinating existing Associate requirements, policies
and procedures with the overlay of international legal requirements will provide
the potential for increased risk to the Company. See "Business-Product
Distribution System-Management of Associates."
 
    The Company's network marketing system is or may be subject to or affected
by extensive government regulation, including, without limitation, federal and
state regulation regarding network marketing plans, and the offer and sale of
business franchises, business opportunities and securities. Various governmental
agencies monitor direct selling activities, and the Company has occasionally
been requested to supply information regarding its marketing plan to certain of
such agencies. There can be no assurance that legislation and regulations
adopted in particular jurisdictions in the future will not
 
                                       9
<PAGE>
adversely affect the Company's business, results of operations and financial
condition. The Company also could be found to be in non-compliance with existing
statutes or regulations as a result of, among other things, vicarious liability
arising from allegations of misconduct and misconduct by Associates, who are
independent contractors over whom the Company has limited control, the ambiguous
nature of certain of such statutes, regulations and related court decisions, and
the considerable interpretive and enforcement discretion statutorily granted to
regulatory authorities and the courts. Any assertion or determination that the
Company or the Associates are not in compliance with existing statutes or
regulations could have a material adverse effect on the Company's business,
results of operations and financial condition. Furthermore, an adverse
determination by any one state could influence the decisions of regulatory
authorities in other jurisdictions. See "Business-Product Distribution
System-Management of Associates."
 
    ABILITY TO MANAGE GROWTH.  The Company's officers have had limited
experience in managing companies as large as the Company. Further growth and
expansion of the Company's business would place additional demands upon the
Company's current management and other resources and would require additional
production capacity, working capital, information systems, management,
operational and other financial resources. Further growth of the Company will
depend on various factors, including, among others, its ability to attract and
retain new Associates, the development of new products, competition and federal
and state regulation of the nutritional supplements industry. Not all of the
foregoing factors are within the control of the Company. No assurance can be
given that the Company's business will grow in the future and that the Company
will be able to effectively manage such growth. If the Company is unable to
manage growth effectively, the Company's business, results of operations and
financial condition would be materially adversely affected. See "Business-Growth
Strategy," "-Product Distribution System-Associate Development," "-Product
Distribution System-Management of Associates," "-Information Technology and
Systems," "-Production and Distribution" and "Management."
 
    COMPETITION.  The nutritional supplements market is large and intensely
competitive. The Company competes directly with companies that manufacture and
market nutritional products in each of the Company's product lines, including
General Nutrition Companies, Inc., Solgar Vitamin and Herb Company, Inc.,
Twinlab Corporation and Weider Nutrition International, Inc. Many of the
Company's competitors in the nutritional supplements market have longer
operating histories and greater name recognition and financial resources than
the Company. In addition, nutritional supplements can be purchased in a wide
variety of channels of distribution. While the Company believes that consumers
appreciate the convenience of ordering products from home through a sales
person, the buying habits of many consumers accustomed to purchasing products
through traditional retail channels are difficult to change. The Company's
product offerings in each product category are also relatively small compared to
the wide variety of products offered by many other nutritional supplement
companies. There can be no assurance that the Company's business, results of
operations and financial condition will not be adversely affected by market
conditions and competition in the future.
 
    The Company also competes in the nutritional supplements market and for new
Associates with other direct selling organizations, many of which have longer
operating histories and greater name recognition and financial resources than
the Company, including Amway Corporation, Nu Skin Enterprises, Inc., Body Wise
International, Inc., ENVION International, Herbalife International, Inc., Enrich
International, Rexall Showcase International, Forever Living Products, Inc. and
Melaleuca, Inc. The Company competes for new Associates on the basis of its
compensation plan and its proprietary and quality products. The Company believes
that many more direct selling organizations will enter the marketplace as this
channel of distribution expands over the next several years. The Company also
competes for the commitment of its Associates. Given that the pool of
individuals interested in direct selling tends to be limited in each market, the
potential pool of Associates for the Company's products is reduced to the extent
other network marketing companies successfully recruit these individuals into
their businesses. There can be no assurance that other network marketing
companies will not be able to recruit the Company's existing Associates or
deplete the pool of potential Associates in a given market.
 
                                       10
<PAGE>
The competition for Associates from such other companies could have a material
adverse effect on the Company's business, results of operations and financial
condition. See "Business-Competition."
 
    POTENTIAL EFFECTS OF ADVERSE PUBLICITY.  The Company's products contain
vitamins, minerals, herbs and other ingredients that the Company regards as safe
when taken as directed by the Company and that various scientific studies have
suggested may offer health benefits. The Company conducts quality control
testing on its products and, from time to time, conducts or sponsors scientific
studies relating to the benefits of its products. The Company is highly
dependent upon Associate perception of the overall integrity of its business, as
well as the safety and quality of its products and similar products distributed
by other companies which may not adhere to the same quality standards as the
Company. The size of the Company's distribution force and results of operations
can be particularly affected by adverse publicity regarding the Company, or its
competitors, including publicity regarding the legality of network marketing or
the Company's network marketing system, the quality of the Company's products
and product ingredients or those of its competitors, regulatory investigations
of the Company or the Company's competitors and their products, Associate
actions, the Company's management of its Associates and the public's perception
of the Company's Associates and direct selling businesses generally. See
"-Limited Availability of Conclusive Clinical Studies," "Business-Products" and
"-Product Distribution System."
 
   
    RELIANCE ON CERTAIN ASSOCIATES.  The Company's compensation plan allows
Associates to sponsor new Associates. The sponsoring of new Associates creates
multiple Associate levels in the network marketing structure. Sponsored
Associates are referred to as "downline" Associates within the sponsoring
Associates' "downline network." If downline Associates also sponsor new
Associates, additional levels of downline Associates are created, with the new
downline Associates also becoming part of the original sponsor's "downline
network." As a result of this network marketing distribution system, Associates
develop relationships with other Associates. The Company believes that its
revenue is generated from thousands of Associate networks. The loss of a
high-level sponsoring Associate or another key Associate together with a group
of leading Associates in such Associate's downline network, or the loss of a
significant number of Associates for any reason, could adversely affect sales of
the Company's products and impair the Company's ability to attract new
Associates, which would have a material adverse effect on the Company's
business, results of operations and financial condition. As of September 30,
1998, only one of the Company's Associates had executed a non-competition
agreement with the Company. See "Business-Product Distribution System-Associate
Development."
    
 
    RELIANCE ON AND CONCENTRATION OF OUTSIDE MANUFACTURERS.  All of the
Company's products are manufactured by outside manufacturers. The Company's
profit margins and its ability to deliver its existing products on a timely
basis are dependent upon the ability of the outside manufacturers to continue to
supply products that meet the Company's quality standards in a timely and
cost-efficient manner. In response to the Company's growth, relationships were
developed with three large manufacturers in 1997. Currently, substantially all
of the Company's products are produced by these manufacturers. The Company's
ability to enter new markets and sustain satisfactory levels of sales in each
market will be dependent in part upon the ability of these or other suitable
outside manufacturers to reformulate existing products, if necessary to comply
with local regulations or market environments, for introduction into such
markets. Finally, the development of additional new products in the future will
likewise be dependent in part on the services of suitable outside manufacturers.
The failure of any manufacturer to supply products as required by the Company
could have a material adverse effect on the Company's business, results of
operations and financial condition.
 
    The Company currently acquires ingredients solely from suppliers that are
considered by the Company to be the superior suppliers of such ingredients. The
Company believes it has developed dependable alternative sources for all of its
ingredients except Manapol-Registered Trademark- and arabinogalactan, which are
components of the Company's proprietary raw material. The Company believes that,
in the event it is unable to source any ingredients from its current suppliers,
such ingredients could be produced by the Company or replaced with substitute
ingredients. However, any delay in replacing or substituting such ingredients
would have a material adverse effect on the Company's business, results of
operations and financial condition. See "Business-Production and Distribution."
 
                                       11
<PAGE>
    DEPENDENCE ON PROPRIETARY INGREDIENT.  Two ingredients are proprietary to
the Company: (i) Ambrotose-Registered Trademark- Complex, a glyconutritional
dietary supplement consisting of a blend of plant polysaccharides, which is a
component of each of the Company's products; and (ii) Dioscorea Complex, a blend
of herbal extracts. The Company's success will depend in large part on its
ability to protect and promote its proprietary rights to these products, in
particular Ambrotose-Registered Trademark- Complex. The Company has filed a
composition and use of matter patent application for this compound, and has
entered into confidentiality agreements with its manufacturers and suppliers to
protect its proprietary rights. However, there can be no assurance that the
Company will be granted a patent for its Ambrotose-Registered Trademark- Complex
compound or that any such patent granted to the Company will not be
substantially narrower in scope than that sought in the Company's application or
that other means employed by the Company to protect its proprietary rights will
be adequate. Any failure of the Company to protect its proprietary rights would
have a material adverse effect on the Company's business, results of operations
and financial condition.
 
    GOVERNMENT REGULATION OF PRODUCTS AND MARKETING; IMPORT RESTRICTIONS.  In
addition to regulation of its direct selling activities, the Company, in both
its United States and foreign markets, is or will be subject to and affected by
extensive laws, governmental regulations, administrative determinations, court
decisions and similar constraints (as applicable, at the federal, state and
local levels) including, among other things, regulations pertaining to (i) the
formulation, manufacturing, packaging, labeling, distribution, importation, sale
and storage of the Company's products, (ii) product claims and advertising
(including direct claims and advertising by the Company as well as claims and
advertising by Associates, for which the Company may be held responsible), (iii)
the Company's network marketing system, (iv) transfer pricing and similar
regulations that affect the level of foreign taxable income and customs duties
and (v) taxation of Associates, which in some instances may impose an obligation
on the Company to collect the taxes and maintain appropriate records. See
"Business-Government Regulation."
 
    The Company may experience complications regarding health and safety and
food and drug regulations for nutritional products. Many products could require
reformulation to comply with local requirements. In some foreign countries,
certain nutritional products may be considered foods, while other countries may
consider them drugs. New regulations could be adopted or any of the existing
regulations could be changed at any time in a manner that could have a material
adverse effect on the Company's business, results of operations and financial
condition. Duties on imports are a component of national trade and economic
policy and could be changed in a manner that would be materially adverse to the
Company's sales and its competitive position compared to locally produced goods,
in particular in countries where the Company's products would be subject to high
customs duties. In addition, import restrictions in certain countries and
jurisdictions will limit the Company's ability to import products from the
United States. Present or future health and safety or food and drug regulations
could delay or prevent the introduction of new products into a given country or
marketplace or suspend or prohibit the sale of existing products in such country
or marketplace. The occurrence of any of these complications could have a
material adverse effect on the Company's business, results of operations and
financial condition.
 
    If the Company expands into foreign markets, the Company will be affected by
the general stability of foreign governments and the regulatory environment
relating to the degree of acceptance attendant to network marketing generally,
and nutritional supplements and other products of the Company's line,
specifically.
 
   
    DEPENDENCE ON KEY PERSONNEL.  The Company's success will depend largely on
the efforts and abilities of senior management, particularly Charles E.
Fioretti, Chairman of the Board and Chief Executive Officer, and Samuel L.
Caster, President, each a founder of the Company. There can be no assurance that
the Company's existing management team will be able to manage the Company or its
growth or that the Company will be able to attract and retain additional
qualified personnel as needed in the future. Mr. Fioretti has executed an
employment agreement with an initial term of five years, but there can be no
assurance that he will remain with the Company for the full term of such
agreement. The loss of the services of Messrs. Fioretti or Caster or the
services of other members of senior management, or the failure of the Company to
attract and retain additional qualified personnel, could have a material adverse
effect on the Company's business, results of operations and financial condition.
See "Management."

<PAGE>
    GOVERNMENT REGULATION OF DIRECT SELLING ACTIVITIES.  Direct selling
activities are regulated by various governmental agencies. These laws and
regulations are generally intended to prevent fraudulent or deceptive schemes,
often referred to as "pyramid" or "chain sales" schemes, that promise quick
rewards for little or no effort or risk, require high entry costs, use high
pressure recruiting methods and/or do not involve legitimate products. The
Company could be found not to be in material compliance with existing
regulations as a result of, among other things, the considerable interpretative
and enforcement discretion given to regulators or misconduct by Associates. Any
assertion or determination that the Company is not currently, or was not in the
past, in compliance with laws or regulations governing the Company's direct
selling activities could have a material adverse effect on the Company's
business, results of operations and financial condition. In addition, in any
country or jurisdiction, the adoption of new laws or regulations or changes in
the interpretation of existing laws or regulations could generate negative
publicity and/or have a material adverse effect on the Company's business,
results of operations and financial condition. The Company cannot determine the
effect, if any, that future governmental regulations or administrative orders
may have on the Company's business, results of operations and financial
condition. Moreover, governmental regulations in countries where the Company may
in the future commence operations may prevent, delay or limit market entry of
certain products or require the reformulation of such products. Regulatory
action, whether or not it results in a final determination adverse to the
Company, has the potential to create negative publicity, with detrimental
effects on the motivation and recruitment of Associates and, consequently, on
the Company's business, results of operations and financial condition. See
"-Potential Effects of Adverse Publicity," "-Risks Associated with International
Expansion" and "Business-Government Regulation."
 
    As is the case with most network marketing companies, the Company has from
time-to-time received inquiries from various government regulatory authorities
regarding the nature of its business and other issues such as compliance with
local business opportunity laws and Associate sales practices. Although to date
none of these inquiries has resulted in a finding materially adverse to the
Company, adverse publicity resulting from inquiries into the Company's
operations by government agencies could materially adversely affect the
Company's business, results of operations and financial condition. See
"-Potential Effects of Adverse Publicity."
 
    PRODUCT LIABILITY.  Under applicable laws and regulations, the Company, like
any other retailer, distributor or manufacturer of products that are designed to
be ingested by consumers or applied to their bodies, faces an inherent risk of
exposure to product liability claims in the event that the use of its products
results in an allegation of loss or injury. Although the Company has not been
the subject of material product liability claims, no assurance can be given that
the Company may not be exposed to future product liability claims, including,
among other things, that its products contain contaminants or include inadequate
instructions as to use or inadequate warnings concerning side effects and
interactions with other substances. The Company maintains product liability
insurance, however, the successful assertion or settlement of any uninsured
claim, a significant number of insured claims, a claim exceeding the Company's
insurance coverage or adverse publicity associated with any product liability
allegation could have a material adverse effect on the Company's business,
results of operations and financial condition.
 
    One of the Company's products, MVP-TM-, contains country mallow, a plant
which contains an ephedra. Products containing ephedrine have been the subject
of adverse publicity in the United States and other countries relating to
alleged harmful effects, including the deaths of several individuals. The United
States Food and Drug Administration (the "FDA") has received numerous reports of
adverse reactions to the ingestion of a naturally-occurring form of ephedrine
from the Chinese herb, Ma Huang. The FDA has issued a warning to consumers
regarding the possible effects of ephedrine ingestion and has also issued a
proposed regulation for dietary supplements containing ephedrine. The proposed
regulation would prohibit dietary supplements containing eight milligrams or
more of ephedrine alkaloids per serving, and would not permit such products to
contain any other stimulant ingredients. The FDA is also considering whether to
also prohibit diuretic or laxative ingredients in such products. In addition,
the labeling of supplements would be prohibited from suggesting or recommending
conditions of use that
 
                                       13
<PAGE>
would result in an intake of eight milligrams or more of ephedrine alkaloids
within a six-hour period, or a total daily intake of 24 milligrams or more. The
FDA proposal would also require a warning not to take the product for more than
seven days, and would prohibit the supplements from being represented, either
expressly or implicitly, as being suitable for long-term uses, such as for
weight loss or body building. Similarly, claims for increased energy, increased
mental concentration or enhanced well-being that might encourage the consumer to
take more of the product to achieve more of the purported effect would be
required to be accompanied by a warning stating that taking more than the
recommended serving may cause a heart attack, stroke, seizure or death. If the
proposed regulation were to be implemented, MVP would be subject to its labeling
requirements and possibly to reformulation. Company sales of MVP were $3.8
million, $5.5 million and $5.9 million in 1995, 1996 and 1997, respectively.
Moreover, depending on claims made for the product, the FDA could regulate it as
a drug, thus requiring product approval prior to marketing. The negative
publicity or product liability claims that could stem from such actions could
have a material adverse effect on the Company's business, results of operation
and financial condition.
 
    LIMITED AVAILABILITY OF CONCLUSIVE CLINICAL STUDIES.  In general, the
Company's products consist of food, nutritional supplements and topical
products, one of which, Emprizone-Registered Trademark-, is classified in the
United States as an "over-the-counter" ("OTC") drug which the Company believes
does not require approval from the FDA or other regulatory agencies prior to
sale. Although many of the ingredients in the Company's products are vitamins,
minerals, herbs and other substances for which there is a long history of human
consumption, some of the Company's products contain innovative ingredients or
combinations of ingredients. Although the Company believes all of its products
to be safe when taken as directed by the Company, there is little long-term
experience with human consumption of certain of these innovative product
ingredients or combinations thereof in concentrated form. Accordingly, there can
be no assurance that the Company's products, even when used as directed, will
have the effects intended or will not have harmful side effects. The Company
performs research and/or tests in connection with the formulation and production
of its products, and from time to time conducts or sponsors clinical studies.
See "-Product Liability."
 
    VARIATIONS IN OPERATING RESULTS.  The Company may experience variations on a
quarterly basis in its results of operations, in response to, among other
things, the timing of Company-sponsored Associate events; new product
introductions; the opening of new markets; the timing of holidays, especially in
the fourth quarter, which may reduce the amount of time Associates spend selling
the Company's products or recruiting new Associates; the adverse effect of
Associates' or the Company's failure, and allegations of their failure, to
comply with applicable government regulations; the negative impact of changes in
or interpretations of regulations that may limit or restrict the sale of certain
of the Company's products; the operation of its network marketing system; the
introduction of its products into each market; the recruitment and retention of
Associates; the inability of the Company to introduce new products or the
introduction of new products by the Company's competitors; general conditions in
the nutritional supplement and personal care industries or the network marketing
industry; and consumer perceptions of the Company's products and operations. In
particular, because the Company's products are ingested by consumers or applied
to their bodies, the Company is highly dependent upon consumers' perception of
the safety, quality and effectiveness of its products. As a result, substantial
negative publicity, whether founded or unfounded, concerning one or more of the
Company's products or other products similar to the Company's products could
adversely affect the Company's business, results of operations and financial
condition.
 
    As a result of these and other factors the Company's quarterly revenues,
expenses and results of operations could vary significantly in the future, and
period-to-period comparisons should not be relied upon as indications of future
performance. There can be no assurance that the Company will be able to increase
its revenues in future periods or be able to sustain its level of revenue or its
rate of revenue growth on a quarterly or annual basis. The Company's rate of
growth compared to previous periods has been decreasing in recent periods and
this trend is expected to continue as the Company matures. Furthermore, no
assurances can be given that the Company's revenue growth rate in new markets
where
 
                                       14
<PAGE>
operations have not commenced will follow this pattern. Due to the foregoing
factors, the Company's future results of operations could be below the
expectations of public market analysts and investors. In such event, the market
price of the Common Stock would likely be materially adversely affected. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."
 
   
    CONTROL BY INSIDERS.  Assuming the sale of 2,500,000 shares and 5,295,015
shares of Common Stock in this offering, Charles E. Fioretti, Samuel L. Caster
and the Company's other directors and officers, together with members of their
families and entities that may be deemed affiliates of or related to such
persons or entities, will, upon completion of this offering beneficially own
approximately 52.6% and 42.9%, respectively, of the Common Stock outstanding.
These individuals are likely to be able to maintain effective control of the
Company, including the ability to elect a majority of the Board of Directors of
the Company. In addition, such a high level of ownership by such persons may
have a significant effect in delaying, deferring or preventing a change in
control of the Company or other events which could be of benefit to the
Company's other shareholders including mergers, acquisitions, tender offers and
proxy contests. Accordingly, holders of Common Stock may be deprived of an
opportunity to sell their shares at a premium to the price paid for such shares.
See "Principal and Selling Shareholders."
    
 
   
    UNSPECIFIED USE OF PROCEEDS.  The principal purposes of this offering are to
provide the capital for international expansion, to increase the Company's
working capital and financial flexibility, to facilitate future access by the
Company to public equity markets and to provide increased visibility,
credibility and name recognition for the Company in the marketplace where
several of its competitors are publicly held companies. In addition, the Company
intends to repay its existing capital lease debt of approximately $1.6 million
if the maximum offering level is achieved. Prior to completion of this offering,
the Company intends to continue to pay approximately $1.3 million in dividends
to its existing shareholders. This dividend will be limited by the pre-offering
earnings of the Company. To the extent the Company sells less than all of the
shares offered by it in this offering, fewer net proceeds will be available to
fund these intended uses. The Company has not yet identified specific uses for a
majority of the net proceeds, and, pending such uses, the Company expects that
it will invest such net proceeds in short-term, interest-bearing
investment-grade securities. Accordingly, the Company's management will have
broad discretion as to the use of such net proceeds without any action or
approval of the Company's shareholders. See "Use of Proceeds."
    
 
    PREFERRED STOCK.  The Board of Directors may from time to time authorize the
issuance of one or more classes or series of Preferred Stock without shareholder
approval and may change the number of shares constituting any series and fix and
determine the designation and preferences, limitations and relative rights,
including voting rights, of the shares of any series of Preferred Stock so
established, in each case without any action or vote by the shareholders.
 
    One of the effects of undesignated Preferred Stock may be to enable the
Board of Directors to discourage an attempt to obtain control of the Company by
means of a tender offer, proxy contest, merger or otherwise, and thereby protect
the Company's management, which may adversely affect the rights of the holders
of Common Stock. Preferred Stock issued by the Company may rank senior to the
Common Stock as to dividend rights, liquidation preference or both, may have
full or limited voting rights and may be convertible into shares of Common
Stock. Accordingly, the issuance of shares of Preferred Stock may discourage
bids for the Common Stock or may otherwise adversely affect the trading price of
the Common Stock.
 
    RISKS ASSOCIATED WITH INFORMATION TECHNOLOGY.  The Company is fundamentally
dependent upon information technology and its related systems to manage and
operate its key business functions: order processing, customer service,
distribution, commission processing, and paying and receiving. The Company
recently implemented an internally developed computer software system, creating
certain risks to its operations. The most immediate risk to the business
operations of the Company is during the implementation phase, in which the new
computer software is substituted for the prior software. During this period,
certain variances between business requirements and the actual software
functionality have been and will continue to be identified and ameliorated in a
real-time environment. Additionally, there
 
                                       15
<PAGE>
will have been and will continue to be deviations in user job performance and
efficiency of an unknown duration, resulting from lack of proficiency with
respect to the requirements of the new software, diminished access to
significant business information, and inherent resistance to change. There have
been, and it is anticipated that there will continue to be, periods during which
the software system will not be optimally functional or periods during which it
will be rendered temporarily inoperative while it is adjusted to achieve
required performance. Moreover, varied computational results may ensue during
the period of adjustment of the software system to allow for all of the
requisites of the Company's specific business environment. During this period,
it can be anticipated that related adverse effects could result in other areas
dependent upon information systems for functionality. Also, it is likely that
during such period, reversion to manual methods, such as written order-taking
and computation may be required during times of adjustment, thereby
substantially decreasing the efficiency of the Company's operations, and
possibly adding, temporarily, to overall costs attendant to such operations.
Standard accounting and inventory functions are currently supported by an
off-the-shelf software package known as CS/3, provided by Tetra International,
Inc. The reliability of inventory information contained within this system is
entirely dependent on the accuracy of data retained in the core custom system.
However, regular manual reconciliation of inventory diminishes this risk over
the long term.
 
    In the event that the software system should fail, the Company would
experience an inability to conduct its day-to-day business for a period of time
dependent upon the severity of the failure and the ability of the Company to
remedy the cause. Should such a failure occur, it could have a material adverse
effect on the Company's business results of operations and financial condition.
 
    ANTI-TAKEOVER MATTERS.  Certain provisions of the Company's Amended and
Restated Articles of Incorporation (the "Articles"), the Company's Amended and
Restated Bylaws (the "Bylaws") and the Texas Business Corporation Act (the
"TBCA") may have the effect of discouraging unsolicited proposals for
acquisition of the Company. The Company's Bylaws provide for a classified Board
of Directors serving staggered terms of three years. Additionally, the Board of
Directors has the authority to issue up to 1,000,000 shares of preferred stock
having such rights, preferences and privileges as are designated by the Board of
Directors without shareholder approval. Effective September 1, 1997, the TBCA
restricts certain business combinations with any "affiliated shareholder," as
defined therein. These provisions may have the effect of delaying, deterring or
preventing a takeover of the Company and could limit the price that certain
investors might be willing to pay in the future for the Common Stock. See
"Description of Capital Stock-Preferred Stock" and "-Anti-Takeover
Considerations."
 
    DILUTION TO NEW INVESTORS.  Purchasers of Common Stock in this offering will
incur immediate and substantial dilution in net tangible book value per share.

    The net proceeds to the Company from the sale of the 1,500,000 shares and
2,200,000 shares of Common Stock offered by the Company hereby at an assumed
initial public offering price of $8.00 per share, after deducting sales
commissions and offering expenses payable by the Company, estimated to total
approximately $940,000 and $1,164,000, respectively, are $11,060,000 and
$16,436,000, respectively. The Company will not receive any proceeds from the
sale of shares by the Selling Shareholders. See "Principal and Selling
Shareholders."
    
 
    The following table sets forth the Company's anticipated use of the net
offering proceeds, assuming the sale, respectively, of the minimum of 1,500,000
shares and the maximum of 2,200,000 shares of Common Stock offered by the
Company hereby. Pending application of the net proceeds, the Company will invest
such proceeds in short term, interest-bearing instruments and investment grade
securities.

    The Company intends to use proceeds from this offering to complete its
expansion into Australia and to begin its expansion into the United Kingdom. The
Company also intends to use proceeds from this offering to finance its working

                                DIVIDEND POLICY
 
   
    The Company has in the past paid dividends to its shareholders, including
dividends in 1997 in the aggregate amount of $6,928,547. In the first nine
months of 1998, the Company paid an aggregate of $9,273,830 in dividends to its
shareholders. The Company currently intends to declare monthly dividends of up
to $0.06 per share until consummation of this offering. Such dividends are
expected to be paid entirely out of pre-offering earnings, and therefore are not
expected to have a dilutive effect on equity. Following this offering, the
Company currently does not anticipate that any dividends will be paid on its
Common Stock in the foreseeable future. The Company intends from time to time to
re-evaluate this policy based on its net income and its alternative uses for
retained earnings, if any. Any future payments of dividends will be subject to
the discretion of the Board of Directors and subject to certain limitations
under the TBCA. The timing, amount and form of dividends, if any, will depend,
among other things, on the Company's results of operations, financial condition,
cash requirements and other factors deemed relevant by the Board of Directors.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
    The following discussion and analysis of the Company's financial condition
and results of operations should be read in conjunction with the Financial
Statements and Notes thereto included elsewhere in this Prospectus.
 
OVERVIEW
 
   
    Mannatech develops and sells proprietary nutritional supplements and topical
products through a network marketing system. The Company sells its products in
the United States and Canada, through a network of approximately 226,000 active
Associates as of September 30, 1998, and is currently planning to expand into
Australia, while continuing to assess the potential of other foreign markets.
    
 
    Since commencement of operations in November 1993, the Company has achieved
year-to-year growth in net sales. This growth is primarily attributable to the
increase in both existing and new product sales, growth in the number of
Associates and expansion into new geographic markets in the United States and
Canada.
 
   
    The Company's revenues are derived primarily from sales of its products,
sales of Associate starter and renewal packs, which include products,
promotional materials, and free admission to the Company events and promotional
materials. To become an Associate of the Company, a person may enroll as a
Preferred Customer and subsequently execute an Associate Application, sponsor
new Associates or purchase a starter pack. Alternatively, one can become an
Associate by purchasing one of the Associate starter packs. Each starter pack
includes some combination of nutritional products, promotional materials, and
free admission to events. Each pack also allows the Associate to purchase
product at the Company's wholesale price. The components, purchase price of the
pack, and wholesale value of the included items for the periods for which
financial data is presented are detailed in the table below.

    The Company views the nutritional product sale included in the "New
Associate Promo Pack" as a retail sale. Viewed as a retail sale the value of the
product would be $39.00 and the total value of the pack would be $51.59. The
Company adopted this view as purchasers of the "New Associate Promo Pack" were
often previously retail customers of other Associates before seeking Associate
status themselves.
 
   
    The Company also requires an Associate to renew status each year by renewing
as a Preferred Customer and continuing to sponsor New Associates or by
purchasing a renewal pack. Prior to June 1998 the Associates renewed at the
$49.00, $229.00, and $568.00 levels. Currently, the Associate can renew at the
$29.00, $200.00 or $350.00 levels. The renewal packs were identical to the
starter packs in the table above sold at the same price. If an Associate chose
not to renew his Associate status he could continue to purchase the Company's
products at the wholesale price and resell the products if he desired; however,
he would not be qualified to earn commissions or bonuses under the Company's
compensation plan. In May 1998 the Company instituted its $29.00 Preferred
Customer Pack, which also provides a method of renewal of Associate status.
    
 
    Associates are also eligible to purchase upgrade packs. Historically,
upgrade packs were purchased at the $229.00, $339.00, $568.00 and $1,000.00
levels. Beginning June 1998 upgrade packs are priced at $289.00, $375.00,
$664.00 and $1,000.00. Upgrade packs are accounted for as renewal packs as they
renew an Associates membership for one year from the time of upgrade.
 
   
    In May 1998, the Company introduced a new starter and renewal pack priced at
$29.00 which consists of 15 promotional materials which would cost $14.50 if
purchased separately at their wholesale value.
    
 
   
    Revenues are generally recognized when products or sales aids are shipped.
The Company's revenues are based primarily on the wholesale prices of the
products sold. The Company defers revenue received from the sale of promotional
packs which is in excess of the wholesale value of the individual items included
in such packs. Revenues from promotional packs are allocated between products
and events admission based on the proportionate fair value of these items.
Allocated event revenues are also deferred. All deferred revenue is amortized
over a twelve-month period. Total deferred revenue was approximately $521,000
and $809,000 at December 31, 1996 and 1997, respectively and was $641,000 for
the nine-month period ended September 30, 1998. The Company currently outsources
all of its product manufacturing needs and all of its ingredients are supplied
by outside vendors.
    
 
    As a result of the Company's expansion into Canada, and its change, in the
fourth quarter of 1997, to higher quality manufacturers, the Company has
experienced an increase in cost of sales as a percentage of net sales. Sales of
products in Canada have also resulted in increased shipping costs and additional
costs to reformulate certain products.
 
    Associates are compensated by commissions, which are directly correlated to
the placement and position of the Associate within the Company's compensation
plan, volume of direct sales and number of
 
                                       24
<PAGE>
   
new enrolled Associates. Commissions as a percentage of net sales were 38.5,
40.7, 41.0 and 39.8 for 1995, 1996, 1997 and the nine months ended September 30,
1998, respectively. The Company believes that, under the Company's existing
compensation plan, commissions will not exceed 42% of net sales. See
"Business-Product Distribution System-Associate Compensation."
    
 
    The Company's selling and administrative expenses consist of human resource
expense, including wages, bonuses and marketing expenses, and are a mixture of
both fixed and variable expenses. Company-sponsored Associate events held
throughout the year also have an effect on its selling and administrative
expenses, as does the Company's continuing commitment to investment in
information technology systems. In 1997, the Company recorded sales and
administrative expenses at 18.5% of net sales, a lower rate than prior years, as
a result of increased net sales, a reduction in executive salaries beginning in
June 1997 and the management of expenses.
 
    The increased demand for the Company's products has necessitated significant
investment in infrastructure to support the growth of the Company. In 1997, the
Company invested in its new headquarters building, new distribution center and
new research and development laboratory. As a result of its investment in
infrastructure, the Company's other operating costs have increased
significantly.
 
    The Company is subject to taxation in the United States at the federal
statutory tax rates of 34% for 1995 and 1996 and 35% for 1997 and 1998. The
Company is also subject to taxation in various state jurisdictions with an
average statutory tax rate of approximately 5%. With the expected international
expansion, a portion of the Company's income will be subject to taxation in the
country in which it operates and the Company may be eligible for foreign tax
credits for the amount of foreign taxes paid in a given period to offset taxes
otherwise payable. The Company may not be able to fully utilize such foreign tax
credits in the United States. The use of the foreign tax credits would be based
upon the proportionate amount of net sales in each country. This could result in
the Company paying a higher overall effective tax rate on its worldwide
operations. Many of the countries in which the Company is considering for
expansion during 1998 and beyond have maximum statutory tax rates in excess of
the United States rate.
 
REORGANIZATION
 
    In December 1994, to achieve certain tax efficiencies and to protect certain
of the Company's proprietary rights, the Company transferred certain rights and
interest in intellectual property, its right to use a supplier's trademark and
its marketing rights to two affiliated partnerships (the "Royalty Partnership"
and the "Marketing Partnership," respectively). The Marketing Partnership was
owned by two affiliated partnerships that also shared common ownership with the
Company (collectively with the Royalty Partnership and the Marketing
Partnership, the "Partnerships"). The respective ownership interests in the
Partnerships were structured with the intention of retaining the same economic
interests among the partners as that of the shareholders of the Company. In the
case of the intellectual property and trademark transferred to the Royalty
Partnership, the Company entered into a 17-year agreement with the Royalty
Partnership to pay a royalty based on sales volume. In the case of the Marketing
Partnership, the Company paid a commission based on a specified percentage of
sales volume. At the time of transfer, the rights and interest in intellectual
property, supplier's trademark and marketing rights had a minimal basis. During
1994, the Company also entered into separate incentive compensation agreements
with two of its shareholders pursuant to which the Company agreed to pay
commissions based on specified monthly sales volumes and increases in number of
new enrolled Associates. These agreements were designed to compensate for the
differences in ownership in the Partnerships for one of the principal
shareholders and to provide compensation to a shareholder in lieu of receiving a
Partnership interest.
 
                                       25
<PAGE>
    On June 1, 1997, in order to simplify the Company's ownership structure and
consolidate all operating activities, the Company entered into agreements to
effect the Reorganization through merging with the corporate general partners of
the Partnerships in which the Company was the surviving corporation and
exchanging shares of Common Stock for the entire ownership interests of the
Partnerships. Pursuant to the Reorganization, the Company issued an aggregate of
10,000,000 shares of Common Stock to holders of the general partnership and
limited partnership interests. In addition, during May and June 1997 the Company
issued 2,027,571 shares of Common Stock in consideration for the cancellation of
incentive compensation agreements with two shareholder-employees and four other
employees of the Company, including 626,971 shares issued to cancel incentive
compensation agreements that had been provided in lieu of ownership interests in
the Partnerships. See Note 9 to the Financial Statements. The net effect of the
foregoing transactions was to increase the number of shares of Common Stock
outstanding by 12,027,571 while retaining substantially the same relative
ownership of the Company. The only ownership percentage change among the
original shareholders related to 208,024 shares granted to one shareholder in
recognition of significant contributions to the Company, which resulted in minor
dilution to the other original seven shareholders at the time of the exchange.
No monetary consideration changed hands and the changes were designed to
reestablish the original economic characteristics of the Company. Other than the
new shares issued to the four employees to cancel their incentive compensation
agreements, relative ownership interests, as evidenced by retention of economic
risks and benefits, remained virtually the same. After the exchange, the Company
terminated and liquidated the Partnerships at no gain or loss.

NINE MONTHS ENDED SEPTEMBER 30, 1998 AND SEPTEMBER 30, 1997
    
 
   
    NET SALES.  Net sales increased 10.62% to $122.9 million for the nine months
ended September 30, 1998 from $111.1 million for the nine months ended September
30, 1997. This increase was primarily attributable to the following:
    
 
   
    - $6.3 million, or 53.4% was due to the sale of several new products
      introduced during 1998 and existing products which were not available for
      sale during the first nine months of 1997 for Canada.
    
 
   
    - $12.2 million, or 103.4% was due to an increase in existing product sales,
      which increase resulted solely from increases in volumes of products sold.
    
 
   
    - ($6.7) million, or (56.8%) was due to an overall decrease in Associate
      pack sales. The decrease resulted from a decrease of approximately ($7.4)
      million in Associate packs sold with respect to the enrollment of new
      Associates offset by a $700,000 increase in packs sold to Associates
      renewing their association with the Company. The Company's fee structure
      remained constant throughout this period; however; the Company added some
      additional packs. See "Business". Associate pack sales decreased due to a
      delay in introducing new Associate packs or starter packs until the second
      quarter of 1998. The Company believes, based upon information received
      from many of its Associates, that many Associates delayed signing up new
      Associates and their own renewal until the new packs were available and
      the Company's operations in Australia had begun. As the new Associate
      packs were not available until May 1998, it is not possible to determine
      if the overall decrease in Associate pack sales was attributable to a
      deferral of such revenue or a permanent loss.
    
 
   
    COST OF SALES.  Cost of sales increased 15.2% to $20.6 million for the nine
months ended September 30, 1998 from $17.9 million for the comparable period in
1997. As a percentage of net sales, costs of sales increased to 16.8% from 16.1%
for the nine months ended September 30, 1998 and 1997, respectively. The
increase in cost of sales was due to a $2.7 million increase in finished goods,
a ($100,000) decrease in freight due to changing vendors to save shipping costs
which was offset by an increase in sales volume and a $100,000 increase in
normal costs of spoilage and shrinkage of inventory which was due to the Company
utilizing a new vendor to blend some of their raw materials used in their
products.
    
 
   
    COMMISSIONS.  Commissions consist of payments to Associates for sales
activity and downline growth. Commissions increased 8.6% to $49.0 million for
the nine months ended September 30, 1998 from $45.5 million for the comparable
period in 1997. As a percentage of net sales commissions decreased to 39.8% for
the nine months ended September 30, 1998 from 40.9% for the comparable period in
1997. The slight decrease as a percentage of sales was the direct result of
decrease in the number of Associate packs sold.
    
 
   
    GROSS PROFIT.  Gross Profit increased 10.7% to $53.3 million for the nine
months ended September 30, 1998 from $47.7 million for the comparable period in
1997. As a percentage of net sales, gross profit increased to 43.4% for the nine
months ended September 30, 1998 from 43.0% for the comparable period in 1997.
These changes were primarily attributable to the factors described above.
    
 
   
    SELLING AND ADMINISTRATIVE EXPENSES.  Selling and administrative expenses
consist of human resource expenses, including wages, bonuses and marketing
expenses, and are a mixture of both fixed and variable expenses. Selling and
administrative expenses increased 13.6% to $22.6 million for the nine months
ended September 30, 1998 from $19.9 million for the comparable period in 1997.
As a percentage of net sales, selling and administrative expenses increased to
18.4% for the nine months ended September 30, 1998 from 17.9% for the comparable
period in 1997. The dollar amount increase was due primarily to sales increases
and $1.0 million expended on the Company's first large scale Associate meeting.
    
 
                                       27
<PAGE>
   
    OTHER OPERATING EXPENSES.  Other operating costs include utilities,
depreciation, travel, office supplies and printing expenses. Other operating
costs increased 17.2% to $15.7 million for the nine months ended September 30,
1998 from $13.4 million for the comparable period in 1997. As a percentage of
net sales, other operating costs increased to 12.8% for the nine months ended
September 30, 1998 from 12.1% for the comparable period in 1997. The dollar
amount increase was primarily related to the increase in sales, additional
expenses of $700,000 related to the opening of Australia, additional
depreciation expense of $700,000 related to the addition of the laboratory
located in the Company's worldwide headquarters, relocation of the distribution
center to its current location in January 1998 and the incurrence of various
other costs associated with the Company's planned international expansion. The
remaining increase was due to the increase in sales volume.
    
 
   
    CANCELLATION OF INCENTIVE COMPENSATION AGREEMENTS.  Cancellation of
incentive compensation agreements consisted of a one-time charge in 1997
totaling approximately $1.8 million at the end of the third quarter of 1997.
This charge resulted from the exchange of Common Stock for the cancellation of
certain incentive compensation agreements. There were no additional
cancellations during 1998. See "Certain Transactions."
    
 
   
    WRITE-OFF OF DEFERRED OFFERING COSTS.  During July 1998 the Company withdrew
its original institutional/retail offering. Approximately $940,000 related to
the withdrawn offering, such as underwriting expenses, printing costs and
roadshow costs, was expensed in the third quarter of 1998.
    
 
   
    OTHER (INCOME) EXPENSE, NET.  Other (income) expense consists of interest
income, royalties from vendors and settlement of lawsuits. Other (income)
expense decreased (102.3%) to $4,000 for the nine months ended September 30,
1998 from ($174,000) for the comparable period in 1997. As a percentage of net
sales, other (income) expense decreased to 0.0% in the first nine months ended
September 30, 1998 from (0.2%) for the comparable period in 1997. The expense
for the first nine months ended September 30, 1997 related primarily to legal
actions and related charges for the settlement of lawsuits totaling $110,000
that did not occur for the comparable period in 1998.
    
 
   
    INCOME TAX EXPENSE.  Income tax expense increased 54.3% to $5.4 million for
the nine months ended September 30, 1998 compared to $3.5 million for the
comparable period in 1997. The effective tax rate increased to 38.5% for the
nine months ended September 30, 1998 from 26.9% for the comparable period in
1997. The increase in the effective tax rate was primarily the result of the
Company's reorganization, which began June 1, 1997. Prior to that date, the
income from the Partnerships was subject to income tax only at the individual
partners' level. See "Certain Transactions."
    
 
   
    NET INCOME.  Net income decreased (7.52%) to $8.6 million for the nine
months ended September 30, 1998 from $8.9 million for the comparable period in
1997. As a percentage of net sales, net income decreased to 7.0% for the nine
months ended September 30, 1998 from 8.1% for the comparable period in 1997. The
increase was primarily related to the increase in sales offset by the recording
of the write-off of the initial public offering expenses of approximately $1
million.
    
 
YEARS ENDED DECEMBER 31, 1997 AND DECEMBER 31, 1996
 
    NET SALES.  Net sales increased 74.4% to $150.6 million in 1997 from $86.3
million in 1996. This increase was primarily attributable to the following:
 
    - $46.9 million, or 72.9%, was due to an increase in existing product sales,
      which increase resulted solely from increases in the volume of products
      sold.
 
   
    - $11.1 million, or 17.3%, was due to an increase in Associate pack sales.
      Associate pack sales increased due to the enrollment of new Associates and
      the sale of renewal packs to existing Associates. Approximately $5.9
      million of the increase in Associate pack sales related to the sign up of
      new Associates and $5.2 million related to the renewal of existing
      Associates. The Company's fee structure remained constant throughout this
      period.
    
 
                                       28
<PAGE>
    - $6.3 million, or 9.8%, was due to the introduction in July 1997 of
      MannaCleanse-TM-, an intestinal support product, and Bulk
      Ambrotose-Registered Trademark-, a cell-to-cell communication support
      product.
 
   
    COST OF SALES.  Cost of sales increased 84.3% to $24.7 million in 1997 from
$13.4 million in 1996. As a percentage of net sales, cost of sales increased to
16.4% for 1997 from 15.5% in 1996. The increase in cost of sales was due to a
$10.8 million increase in sales of finished goods, a $600,000 increase in
shipping costs due to increased sales volume, a $300,000 increase in shipping
costs for Canadian finished goods and a ($400,000) decrease in normal costs of
spoilage and shrinkage of inventory.
    
 
    COMMISSIONS.  Commissions increased 75.4% to $61.7 million in 1997 from
$35.2 million in 1996. As a percentage of net sales, commissions increased to
41.0% for 1997 from 40.7% in 1996.
 
    GROSS PROFIT.  Gross profit increased 70.0% to $64.2 million in 1997 from
$37.8 million in 1996. As a percentage of net sales, gross profit decreased to
42.6% in 1997 from 43.8% in 1996. These changes were primarily attributable to
the factors described above.
 
    SELLING AND ADMINISTRATIVE EXPENSES.  Selling and administrative expenses
increased 56.8% to $27.8 million in 1997 from $17.8 million in 1996. As a
percentage of net sales, selling and administrative expenses decreased to 18.5%
in 1997 from 20.6% in 1996. The dollar amount increase was primarily
attributable to an increase in bonuses and compensation paid and an increase in
number of employees to support the Company's growth in net sales. The decrease
in the percentage of net sales was primarily attributable to certain
efficiencies achieved by the Company in managing sales growth and reductions in
executive salaries beginning in June 1997 of approximately $600,000. Executive
salaries were reduced to reflect salaries commensurate with those paid by
similar public companies. The Company does not expect increases in executive
salaries in the foreseeable future other than those increases necessary in the
marketplace to recruit, reward and retain qualified executives.
 
    OTHER OPERATING COSTS.  Other operating costs increased 65.2% to $19.4
million in 1997 from $11.7 million in 1996. This increase was primarily due to
costs associated with the Company's relocation of its worldwide headquarters to
its current location in March 1997. As a result of the relocation the Company
had capital expenditures of approximately $9.6 million, which resulted in an
increase in depreciation expense of approximately $900,000. In addition, other
expenses, comprised of supplies, rent and miscellaneous equipment purchases,
increased by approximately $1.8 million. Utility and telephone expense increased
by approximately $2.0 million with the majority of the increase related to
telephone expense. The increase in telephone expense is related to the increase
in sales as the majority of the Company's sales are made by telephone or fax.
The increased sales volume leads to increased phone usage, which results in
higher costs. As a percentage of net sales, other operating costs decreased to
12.9% in 1997 from 13.6% in 1996. This decrease was primarily attributable to
increased sales volume and the Company achieving certain volume-based
efficiencies due to increased net sales. If sales volumes remain constant, these
volume-based efficiencies are expected to remain constant as they are directly
related to sales volumes.
 
    CANCELLATION OF INCENTIVE COMPENSATION AGREEMENTS.  Cancellation of
incentive compensation agreements consisted of a one-time charge in 1997
totaling approximately $2.2 million. This charge resulted from the exchange of
Common Stock for the cancellation of certain incentive compensation agreements.
See "Certain Transactions."
 
   
    OTHER (INCOME) EXPENSE, NET.  Other (income) expense decreased 62.9% to
($43,000) in 1997 from ($116,000) in 1996. As a percentage of net sales, other
(income) expense decreased to (0.0%) in 1997 from (0.1%) in 1996. The change in
1997 was primarily attributable to the settlement in 1997 of various lawsuits
totaling $110,000 versus settlement expense of $59,000 in 1996.
    
 
    INCOME TAX EXPENSE.  Income tax expense increased to $4.1 million in 1997
compared to $1.2 million in 1996. The effective tax rate increased significantly
to 28.0% in 1997 from 14.3% in 1996. The increase in the effective tax rate was
primarily the result of the Company's reorganization as of June 1,
 
                                       29
<PAGE>
1997. Prior to that date, the Partnerships were subject to income tax only at
the individual partners' level. See "Certain Transactions."
 
    NET INCOME.  Net income increased 48.3% to $10.6 million in 1997 from $7.2
million in 1996. As a percentage of net sales, net income decreased to 7.0% in
1997 compared to 8.3% in 1996. This decrease was primarily related to the
cancellation of the incentive compensation agreements, additional income tax
expense and the reorganization of the Partnerships. See "Certain Transactions."
 
YEARS ENDED DECEMBER 31, 1996 AND DECEMBER 31, 1995
 
    NET SALES.  Net sales increased 169.1% to $86.3 million in 1996 from $32.1
million in 1995. This increase was primarily attributable to the following:
 
    - $29.4 million, or 54.3%, was due to an increase in existing product sales,
      which increase resulted solely from increases in the volume of products
      sold.
 
   
    - $18.0 million, or 33.2%, was due to an increase in Associate pack sales.
      Associate pack sales increased due to the enrollment of new Associates and
      the sale of renewal packs to existing Associates. Approximately $13.3
      million of the increase in Associate pack sales related to the sign up of
      new Associates and $4.7 million related to the renewal of existing
      Associates. The Company's fee structure remained constant throughout this
      period.
    
 
    - $3.6 million, or 6.6%, was due to the introduction of a new nutritional
      supplement product line, consisting of Profile 1, Profile 2 and Profile 3,
      in May 1996, and the introduction of a new raw material,
      Ambrotose-Registered Trademark-, in October 1996.
 
   
    - $3.2 million, or 5.9%, was due to the commencement of operations in Canada
      in April 1996, excluding Associate pack sales.
    
 
    COST OF SALES.  Cost of sales increased 174.7% to $13.4 million in 1996 from
$4.9 million in 1995. As a percentage of net sales, cost of sales increased to
15.5% in 1996 from 15.2% in 1995. The increase in cost of sales was comprised of
an $8.3 million increase in sales of finished goods and a $200,000 increase in
sales of finished goods in Canada.
 
    COMMISSIONS.  Commissions increased 184.9% to $35.2 million in 1996 from
$12.3 million in 1995. As a percentage of net sales, commissions increased to
40.7% in 1996 from 38.5% in 1995. The increase was primarily attributable to the
introduction of an additional type of commission for the Associates'
compensation plan during 1995. Once a commission plan is introduced, there is
generally a short time lag before the Associates begin to qualify for the
payment of commissions. During 1996, this new commission structure accounted for
a 4.3% increase (as a percentage of net sales) in total commissions.
 
    GROSS PROFIT.  Gross profit increased 154.2% to $37.8 million in 1996 from
$14.9 million in 1995. As a percentage of net sales, gross profit decreased to
43.8% in 1996 from 46.3% in 1995. These changes were primarily attributable to
the factors described above.
 
    SELLING AND ADMINISTRATIVE EXPENSES.  Selling and administrative expenses
increased 153.3% to $17.8 million in 1996 from $7.0 million in 1995. As a
percentage of net sales, selling and administrative expenses decreased to 20.6%
in 1996 from 21.9% in 1995. The dollar amount increase was primarily
attributable to sales increases. The decrease as a percentage of net sales was
primarily attributable to increased sales and the Company achieving certain
sales volume-based efficiencies for human resources and marketing expenses.
 
    OTHER OPERATING COSTS.  Other operating costs increased 123.6% to $11.7
million in 1996 from $5.3 million in 1995. As a percentage of net sales, other
operating costs decreased to 13.6% in 1996 from 16.4% in 1995. The dollar amount
increase was primarily attributable to the increase in sales, which was
 
                                       30
<PAGE>
offset by the Company recording approximately $400,000 in consulting fees
associated with the Company's entry into the Canadian market.
 
   
    OTHER (INCOME) EXPENSE, NET.  Other (income) expense in 1996 increased to
($116,000) from $181,000 in 1995. In 1995, the Company incurred an expense of
$180,600 as a result of the settlement of a lawsuit related to the termination
of a former employee. In 1996, the Company recorded an additional expense of
$59,000 related to the settlement of this lawsuit, which was more than offset by
approximately $160,000 of interest income and royalty income.
    
 
    INCOME TAX EXPENSE.  Income tax expense increased $1.1 million to $1.2
million in 1996 compared to $67,000 in 1995. The effective tax rate increased to
14.3% in 1996 from 2.7% in 1995. The effective tax rate significantly varied
from the statutory rate of 34% primarily due to the $5.8 million of Partnership
income included with the Company's income as discussed previously. See
"-Reorganization" and "Certain Transactions."
 
    NET INCOME.  Net income increased 206.2% to $7.2 million in 1996 from $2.3
million in 1995. As a percentage of net sales, net income increased to 8.3% in
1996 as compared to 7.3% in 1995. The increase was the result of the factors
described above.

(1) For the fourth quarter of 1996 cost of sales included various
    book-to-physical inventory adjustments and write off of identified obsolete
    inventory. Selling and administrative expenses included an accrual for
    discretionary bonuses to all employees and a charge for severance packages.
    Other operating costs increased due to certain year-end accruals for
    attorneys' fees, travel and general operating expenses.

(2) For the fourth quarter of 1997 cost of sales included an adjustment for the
    abnormal conversion of approximately $133,000 of raw materials by a
    manufacturer and a write-off of identified obsolete inventory. The Company
    now sells raw materials to its manufacturers and repurchases finished goods,
    which should prevent future losses on abnormal conversions. Selling and
    administrative expenses included accruals for (i) discretionary bonuses for
    all employees, (ii) termination expenses and (iii) disputed freight
    expenses. Other operating costs increased for the accrual of various
    attorney and consulting fees and compensation expenses related to the
    issuance of stock options to certain nonemployees.
 
   
(3) In September 1998, the Company recorded a charge of approximately $941,000
    for the abandonment of the initial public offering which began in September
    1997.
    
 
   
(4) In June 1997 the Company recorded a one-time charge to operations for the
    issuance of Common Stock in exchange for the cancellation of certain
    incentive compensation agreements. An additional incentive compensation
    agreement was cancelled in December 1997. See "-Reorganization" and "Certain
    Transactions."
    
 
   
(5) The pro forma information shows the Company's net income as if all income
    earned by the Company and the Partnerships was taxable at federal and
    statutory rates.
    
 
    As the table above indicates, the Company has experienced a declining rate
of growth in recent quarters. The decreased rate results primarily from the
increased base on which the growth rate is computed and a shrinking base of
potential new Associates in its existing markets. The Company has relied on its
historical growth to provide the operating cash flows used to fund its current
infrastructure in property, equipment and personnel. The Company believes it
currently has an infrastructure capable of supporting its historical growth for
the next three to five years. The Company does not anticipate that future rates
of growth will be equal to historic rates of growth due to the increased base on
which the rate of growth is computed. The Company's inability to maintain its
historic rate of growth is not expected to have an adverse effect on operations
due to the relatively high gross profit margins and current sales base. The
Company expects expansion into international markets to provide expanded growth
opportunities. If the Company is unable to maintain current levels of growth,
seasonal declines in sales revolving around the holiday period in the fourth
quarter may become apparent.
 
   
    The following table sets forth certain unaudited quarterly results of
operations expressed as a percentage of net sales for each of the eleven
quarters ending with the period ended September 30, 1998.

    The Company may experience variations on a quarterly basis in its results of
operations, in response to, among other things, the timing of Company-sponsored
Associate events; new product introductions;
 
                                       33
<PAGE>
the opening of new markets; the timing of holidays, especially in the fourth
quarter, which may reduce the amount of time Associates spend selling the
Company's products or recruiting new Associates, the adverse effect of
Associates' or the Company's failure, and allegations of their failure, to
comply with applicable government regulations; the negative impact of changes in
or interpretations of regulations that may limit or restrict the sale of certain
of the Company's products; the operation of its network marketing system; the
introduction of its products into each market; the recruitment and retention of
Associates; the inability of the Company to introduce new products or the
introduction of new products by the Company's competitors; general conditions in
the nutritional supplement and personal care industries or the network marketing
industry; and consumer perceptions of the Company's products and operations. In
particular, because the Company's products are ingested by consumers or applied
to their bodies, the Company is highly dependent upon consumers' perception of
the safety, quality and effectiveness of its products. As a result, substantial
negative publicity, whether founded or unfounded, concerning one or more of the
Company's products or other products similar to the Company's products could
adversely affect the Company's business, results of operations and financial
condition.
 
    As a result of these and other factors the Company's quarterly revenues,
expenses and results of operations could vary significantly in the future, and
period-to-period comparisons should not be relied upon as indications of future
performance. There can be no assurance that the Company will be able to increase
its revenues in future periods or be able to sustain its level of revenue or its
rate of revenue growth on a quarterly or annual basis. Furthermore, no
assurances can be given that the Company's revenue growth rate in new markets
where operations have not commenced will follow this pattern. Due to the
foregoing factors, the Company's future results of operations could be below the
expectations of public market analysts and investors. In such event, the market
price of the Common Stock would likely be materially adversely affected.
 
LIQUIDITY AND CAPITAL RESOURCES
 
   
    The Company's principal capital requirement is to fund working capital to
support its growth. To date, the Company has financed its operations primarily
through cash flows derived from operating activities. Primarily as a result of
the Company's investment in the infrastructure necessary to support the rapid
growth of the Company, the Company had working capital deficiencies of $2.6
million, $9.2 million and $11.3 million as of December 31, 1996, December 31,
1997 and September 30, 1998, respectively. During 1997 and the first nine months
of 1998, the Company invested approximately $7.5 million and $4.9 million,
respectively, in its property and equipment. These projects were funded
primarily from operating cash flow which negatively impacted working capital.
The Company also distributed approximately $4.0 million during 1997 to the
Partnerships and approximately $6.9 million and $9.3 million in dividends to its
shareholders in 1997 and the first nine months of 1998, respectively.
Additionally, current liabilities increased due to increased commissions, income
taxes and inventory purchases, all of which are directly related to increased
sales volume in 1997 and the first three months of 1998. The Company believes
its current facilities are sufficient to support near-term growth. The reduction
in capital spending, combined with the Company's intention to cease future
distributions to shareholders, is expected to reduce or eliminate the Company's
working capital deficiencies in the future.
    
 
   
    In January 1998, the Company entered into a $1.5 million interim lease
line-of-credit agreement (the "Line of Credit Agreement") with Banc One Leasing
Corporation to fund the purchase of furniture and certain capital equipment in
connection with the Company's relocation to its new facility. The Line of Credit
Agreement bears interest at the prime interest rate of Bank One, Columbus, NA
plus one-half percent, is secured by the leased assets, is guaranteed by two of
the Company's shareholders and will expire on December 15, 1998. The Line of
Credit Agreement allows the Company to convert amounts drawn thereunder into
capital leases and, in March and August 1998, the Company converted $631,000 and
$840,000, respectively which had been drawn on the Line of Credit Agreement into
a capital lease (the "Capital Lease"). The Capital Lease bears interest at 9.3%,
is collateralized by the leased assets and is payable in 36 installments. In
July 1998, the Company entered into a thirty-six month, unsecured note
    
 
                                       34
<PAGE>
   
payable with an insurance company to finance its product liability insurance
premium. The note bears interest at 8.0%.
    
 
    The Company plans to improve its working capital position, make additional
investments in its new distribution center, research and development laboratory,
and complete its internally developed software program. The Company intends to
fund these initiatives with proceeds from this offering, net cash provided by
operating activities and additional borrowings under the Line of Credit
Agreement described above. See "Use of Proceeds."
 
   
    Net cash provided by operating activities was $3.1 million, $9.6 million,
$19.8 million and $14.8 million in 1995, 1996, 1997 and for the nine months
ended September 30, 1998, respectively. Throughout these periods, the Company
experienced increases in net income as a result of increases in net sales, which
were partially offset by increases in inventories.
    
 
   
    Net cash used in investing activities was $843,000, $3.2 million, $9.3
million and $4.3 million in 1995, 1996, 1997 and the nine months ended September
30, 1998, respectively. These activities consisted primarily of purchases of
property and equipment in connection with the Company's relocation to its new
facility in April 1997, and the relocation of the Company's distribution center
and build out of its research and development facility in the first quarter of
1998.
    
 
   
    Net cash used in financing activities totaled $1.6 million, $6.2 million,
$11.6 million and $9.1 million in 1995, 1996, 1997 and for the nine months ended
September 30, 1998, respectively. In 1995, 1996 and through the reorganization
of the Company in June 1997, the Company made distributions to partners of the
Partnerships. Following the reorganization, the Company has paid dividends on a
monthly basis to its shareholders in the amount of $0.02-$0.06 per share and
expects to continue to pay dividends each month until the consummation of this
offering. See "Dividend Policy."
    
 
   
    The Company anticipates that its existing capital resources, including cash
provided by operating activities and bank borrowings, together with the
anticipated proceeds from this offering, will be adequate to fund the Company's
operations for at least the next 12 months. Of the net proceeds to the Company,
the Company intends to use approximately (i) $6.06 to $9.84 million, depending
upon the number of shares sold in this offering, for international expansion
primarily to be used for product registration, initial inventory requirements,
and similar items, (ii) $5.0 million for working capital and general corporate
purposes and (iii) the repayment of $1.6 million in debt, assuming the sale of
maximum number of shares offered by the Company hereby. The Company has no
present commitments or agreements with respect to any acquisitions or purchases
of manufacturing capabilities, new technologies or raw material sources. There
can be no assurance that changes will not occur that would consume available
capital resources before such time. The Company's capital requirements depend on
numerous factors, including the timing and pace of the Company's entry into
international markets, growth in the number of Associates and its research and
development efforts. To the extent that the Company's existing capital
resources, together with the anticipated proceeds of this offering, are
insufficient to meet its capital requirements, the Company will be required to
raise additional funds. There can be no assurance that additional funding, if
necessary, will be available on favorable terms, if at all.
    
 
RECENT FINANCIAL ACCOUNTING STANDARDS BOARD STATEMENTS
 
    In June 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("FAS") No. 130, "Reporting
Comprehensive Income." FAS 130 establishes standards for the report and display
of comprehensive income and its components (revenues, expenses, gains, and
losses) in a full set of general purpose financial statements. FAS 130 requires
that an enterprise (i) classify items of other comprehensive income by their
nature in a financial statement and (ii) display the accumulated balance of
other comprehensive income separately from retained earnings and additional
paid-in capital in the equity section of a statement of financial position. FAS
130 is effective for fiscal years beginning after December 15, 1997. The Company
does not have any items of other comprehensive income for any period presented.
 
                                       35
<PAGE>
   
    In June 1997, the FASB issued FAS No. 131, "Disclosures about Segments of an
Enterprise and Related Information." FAS 131 established standards for reporting
information about operating segments in annual financial statements and requires
reporting of selected information about operating segments in interim financial
reports issued to shareholders. FAS 131 also establishes standards for related
disclosure about products and services, geographic areas and major customers.
FAS 131 is effective for financial statements for periods beginning after
December 15, 1997, and requires the restatement of disclosures for earlier
periods for comparative purposes unless the information is not readily
available, in which case a description of unavailable information is required.
Currently, this pronouncement is not applicable to the Company.
    
 
    In February 1998, the FASB issued FAS No. 132, "Employers' Disclosures about
Pensions and Other Postretirement Benefits." FAS 132 revises footnote disclosure
requirements for employer pensions and other retiree benefits, standardizes the
disclosure requirements, requires additional information on changes in the
benefit obligations and calculating the fair values of plan assets, and
eliminates certain disclosures. FAS 132 is effective for financial statements
for periods beginning after December 15, 1997. As the Company does not provide a
defined benefit plan, this pronouncement will not impact the Company.
 
    In June 1998, the FASB issued FAS No. 133, "Accounting for Derivatives,
Investments and Hedging Activities." This statement establishes accounting and
reporting standards for derivative financial instruments, including certain
derivative financial instruments imbedded in other contracts and for hedging
activities. FAS 133 is effective for all fiscal quarters beginning after June
15, 1999. As the Company does not have any derivative financial instruments,
this pronouncement will not impact the Company.
 
   
YEAR 2000 COMPLIANCE
    
 
   
    The Company's management recognizes the need to ensure that its operations
and relationships with vendors, Associates and other third parties will not be
adversely impacted by software processing errors arising from calculations using
the Year 2000 and beyond. Many existing computer programs and databases use only
two digits to identify a year in the date field (i.e., 98 would represent 1998).
If not corrected, many computer systems could fail or create erroneous results
in the Year 2000. The Company believes all of its internal information systems
currently in use are Year 2000 ready, largely due to the short operating history
of the Company. The majority of the Company's critical business applications
have been developed internally, in the past two years, with Year 2000 ready
tools. With respect to non-information technology systems issues, the Company is
in the process of identifying, assessing and remediating, if necessary its
building and utility systems for any Year 2000 issues relating to the
functionality of its facilities. All remaining remediation and testing of
non-information technology systems is expected to be performed and completed by
June 30, 1999.
    
 
   
    The Company has begun communications with its vendors and other third
parties to determine the extent that these related systems may not be Year 2000
ready. Because the Company is still in the initial stages of these
communications, the Company can not determine if such failures are possible and,
if so, the extent that such failures would impact the Company. If one of the
Company's primary suppliers of ingredients were to have Year 2000 problems, it
is possible that these problems could have a material effect on the Company's
operations.
    
 
   
    Management expects the total cost associated with Year 2000 identification,
remediation and testing to be between $400,000 and $800,000. The expected costs
represent approximately 5-10% of the total information technology budget. The
Company has spent $20,000 at September 30, 1998 on the Year 2000 issue.
    
 
   
    Should any or all of the applications fail to perform properly on January 1,
2000 the Company will resort to temporary manual processing, which is not
expected to have a material adverse impact on its short-term operations. Failure
to achieve Year 2000 readiness by any of the Company's vendors, while
    
 
                                       36
<PAGE>
   
expected to cause some disruption to operations in the short-term, is not
expected to have a material impact on the Company's operations.
    
 
IMPACT OF INFLATION
 
    The Company believes that inflation has not had a material impact on its
historical operations or profitability.

                                    BUSINESS
 
GENERAL
 
   
    Mannatech develops and sells proprietary nutritional supplements and topical
products through a network marketing system. The Company sells its products in
the United States and Canada, through a network consisting of approximately
226,000 active Associates (an "active" Associate has purchased products from the
Company within the last 12 months) as of September 30, 1998, and is currently
planning to expand into Australia, while continuing to assess the potential of
other foreign markets. Since commencing operations in November 1993, the
Company's sales have grown from approximately $8.4 million in 1994 to
approximately $150.6 million in 1997.
    
 
    The Company pursues a two-fold business strategy: (i) to develop a
proprietary line of nutritional supplements having both health benefits and mass
appeal to a general population demanding non-toxic healthcare alternatives and
(ii) to provide an appealing framework for persons interested in the products to
establish a direct sales business. To date, the Company has focused its
development efforts primarily in the area of carbohydrate technology, creating a
proprietary ingredient, Ambrotose-Registered Trademark- Complex, which combines
the naturally occurring sugars required to support optimal cell-to-cell
communication. Additional Company efforts have been focused on developing
products based on scientific advances in the emerging field of phytochemistry,
which has identified certain naturally occurring components of various plants,
known as "phytochemicals," which, while not essential to sustain life, are
fundamental to optimal health.
 
    Ambrotose-Registered Trademark- Complex is the cornerstone of the Company's
product lines. These products are designed to support various systems and
functions of the human body, including (i) the cell-to-cell communication
system, (ii) the immune system, (iii) the endocrine system, (iv) the intestinal
system and (v) the dermal system. The Company also markets products designed to
aid in sports performance and nutritional support. The Company's products,
Man-Aloe-Registered Trademark-, Ambrotose-Registered Trademark- and Bulk
Ambrotose-Registered Trademark-, are designed to support cell-to-cell
communication. For immune system support, the Company offers
Phyt-Aloe-Registered Trademark-, for adults, and
Phyto-Bears-Registered Trademark-, a chewable gummi-bear nutritional supplement
product marketed to children but popular with adults. Other products include
MVP-TM- and Plus for endocrine system support, MannaCleanse-TM- for intestinal
system support and Emprizone-Registered Trademark-, Firm and Naturalizer for
dermal care. The Company offers several products designed to aid sports
performance by enhancing the body's natural recovery process and supporting lean
tissue development, including Em-Pact-TM-, Bulk Em-Pact-TM- and Sport with
Ambrotose-Registered Trademark-. The Company also markets Profile 1, Profile 2
and Profile 3, which support the body's nutritional needs.
 
   
    In March 1998, the Company introduced MannaBAR-TM-, a nutritional supplement
bar in two versions that contain the equivalent of the Company's recommended
minimum daily supply of Ambrotose-Registered Trademark-Complex,
Phyt-Aloe-Registered Trademark- and Plus. In September 1998 the Company
introduced Manna-C-TM-, a nutritional support for nasal and sinus health
containing Ambrotose-Registered Trademark- Complex, monosaccharides necessary to
the manufacture of glycoproteins and an herbal blend of Vitamin C and other
nutrients which support most cell functions and, in October 1998, released
Ambrostart, a nutritional support fiber drink containing Ambrotose-Registered
Trademark- Complex, and Bulk Phyt-Aloe-Registered Trademark- an immune support
system product. In addition to MannaBAR-TM- and Manna-C-TM-, the Company plans
to release additional products as new nutritional compounds or areas of consumer
demand are identified by the Company. All new products are expected to contain
proprietary components.
    
 
    The Company's products are marketed exclusively through a network marketing
system. The Company believes that its network marketing system is well-suited to
its products, which emphasize health and nutrition, because network marketing
allows in-person product education not available through traditional marketing
techniques. The Company's network marketing system appeals to a broad cross-
section of people, particularly those seeking to supplement family income, start
a home-based business or pursue employment opportunities other than
conventional, full-time employment.

INDUSTRY OVERVIEW
 
    The nutritional supplements industry is highly fragmented and intensely
competitive. It includes companies that manufacture and distribute products
which are generally intended to enhance the body's performance and well being.
Nutritional supplements include vitamins, minerals, dietary supplements, herbs,
botanicals and compounds derived therefrom. Opportunities in the nutritional
supplements industry were enhanced by the enactment of the Dietary Supplement
Health and Education Act of 1994 ("DSHEA"). Under DSHEA, vendors of dietary
supplements are now able to educate consumers regarding the effects of certain
component ingredients.
 
    According to Packaged Facts, an independent consumer market research firm,
the retail market for nutritional supplements has experienced a compound annual
growth rate in the United States of over 15% from 1992 to 1996. Sales in the
principal domestic market in which the Company's products compete totaled
approximately $6.5 billion in 1996. The Company believes that growth in the
nutritional supplement market is driven by several factors, including (i) the
general public's heightened awareness and understanding of the connection
between diet and health, (ii) the aging population, particularly the baby-boomer
generation, which is more likely to consume nutritional supplements, (iii)
product introductions in response to new scientific research and (iv) the
nationwide trend toward preventive medicine.
 
    Nutritional supplements are sold primarily through mass market retailers,
including mass merchandisers, drug stores, supermarkets and discount stores;
health food stores; mail order companies; and direct sales organizations. Direct
selling, of which network marketing is a significant segment, has been enhanced
in the past decade as a distribution channel due to advancements in technology
and communications resulting in improved product distribution and faster
dissemination of information. The distribution of products through network
marketing has grown significantly in recent years. The World Federation of
Direct Selling Associations (the "WFDSA") reports that, from 1990 through 1996,
worldwide direct distribution of goods and services to consumers increased
approximately 65%, resulting in the sale of nearly $80 billion of goods and
services in 1996. According to the "Survey of Attitudes toward Direct Selling,"
commissioned by the Direct Selling Association (the "DSA"), and conducted and
prepared by Wirthlin Worldwide (the "Wirthlin Report"), among the three
categories experiencing the greatest gains in the direct selling industry since
1976 are food, nutrition and wellness products.
 
    According to the Wirthlin Report, approximately 51% of the American public
has purchased products or services from a direct selling company at some point
in the past, with 29% of those having made such a purchase in the last 12
months. Four in 10 adult Americans have expressed an interest in direct selling
as a method of buying products and services, and 23% of those who have never
purchased products and services from direct selling companies are interested in
direct selling. The Company believes it is positioned to capitalize on the
trends of growth in direct sales and demand for nutritional supplement products.
 
OPERATING STRENGTHS
 
    The Company's two-fold business strategy is to (i) develop a proprietary
line of nutritional supplements having both health benefits and mass appeal to a
general population demanding non-toxic healthcare alternatives, and (ii) provide
an appealing framework for persons interested in the products to establish a
direct sales business. The Company believes that it will be able to continue its
growth by capitalizing on the following operating strengths:
 
    PROPRIETARY PRODUCT OFFERINGS.  The Company offers an innovative line of
products based upon its proprietary, patent-pending research. The Company
believes that the discovery and development of products containing certain
carbohydrates necessary to optimum health represents an expanding business
opportunity for the Company. The Company recognized the nutritional need for the
eight known
 
                                       39
<PAGE>
monosaccharides to support optimal health, and developed and filed a patent
application on a compound containing these monosaccharides. The Company includes
this compound, Ambrotose-Registered Trademark-Complex, in each of its products.
The Company believes that maintaining a proprietary line of products is
important for two reasons: (i) it is a marketing factor that differentiates the
Company from its competitors; and (ii) the limited availability helps to drive
demand and enables premium pricing.
 
    SUPERIOR RESEARCH AND DEVELOPMENT CAPABILITY.  The Company believes that its
experienced personnel and new research and development facilities will allow it
to develop and market additional new proprietary products. The Company's
research and development efforts are led by two scientists with an aggregate of
34 years of experience designing products based on emerging carbohydrate
technology. In March 1998, the Company completed construction of a
technologically advanced laboratory to be used for both quality assurance and
product development. As a complement to its in-house staff and facilities, the
Company has sought, and will continue to seek, strategic alliances with several
large manufacturers of nutritional supplements. These companies work with the
Company to create, develop and manufacture its proprietary products and lend
additional guidance which is helpful to the Company's strategic planning. In
addition, the Company works with other smaller product companies to identify and
develop new innovative niche products.
 
   
    STRONG ASSOCIATE SUPPORT PHILOSOPHY.  The Company is committed to providing
the highest level of support services to its Associates. The Company believes
that it meets the needs of, and builds loyalty with, its Associates through its
highly personalized and responsive customer service. Company-sponsored Associate
events held several times throughout the year provide education and motivation
for thousands of Associates. These conferences feature a schedule of events that
offers information, aids in business development for Associates and provides a
venue for Associates to interact with the leading distributors and researchers
of the Company. In addition, the Company believes it offers one of the most
financially rewarding compensation plans offered to Associates in the direct
selling industry. Commissions as a percentage of net sales were 38.5%, 40.7%,
41.0%, and 39.8% for 1995, 1996, 1997 and the nine months ended September 30,
1998, respectively.
    
 
    FLEXIBLE OPERATING STRATEGY.  The Company considers flexibility to be a key
component of its existing and ongoing success. The Company outsources production
and forms strategic alliances to minimize capital expenditure where practicable.
However, the Company maintains control of key operating functions, including
product development and formulation, product warehousing and distribution,
financial and operating functions and proprietary product raw material sourcing.
The Company believes it is positioned to enter international markets in an
efficient and cost-effective manner by leveraging the expertise and resources of
its strategic allies in the areas of distribution and logistics, call center
operations, product registration and export requirements. Information technology
also plays a key role in providing operating flexibility to the Company. The
proprietary technology systems used by the Company are designed to be quickly
and easily adaptable in order to support expansion into new markets. By
developing this technology infrastructure, the Company believes it has reduced
the risks associated with operational inefficiencies typically encountered by
network marketing companies during periods of rapid growth.
 
    EXPERIENCE AND DEPTH OF MANAGEMENT TEAM.  The Company's management team is
comprised of experienced individuals drawn from a variety of backgrounds and
expertise in certain fields, including product research and development,
marketing, direct sales, legal and compliance, information technology and
product distribution. All principal managers have substantial business
experience, most with larger concerns, and bring the perspective of traditional
business to the multi-level marketing endeavor of the Company. The goal of the
management team is to provide a sound, systematic, reliable framework within
which each Associate can fit his or her personal style of conducting business.
 
                                       40

GROWTH STRATEGY
 
    The Company's primary growth strategy is to increase product sales through
existing distribution channels, to continue to expand operations in existing
markets in the United States and Canada and to enter select foreign markets. The
Company believes that its growth will be based on the following factors:
 
    INTRODUCE NEW PRODUCTS.  The Company's product development strategy is to
expand its existing product lines and bring new proprietary and, where possible,
patentable products to market that can be developed into new product lines.
Since its inception, the Company has introduced new products each year,
including, in March 1998, MannaBARs-TM-, which provide a new delivery system for
its proprietary nutritional supplement compounds in the form of bars made from
whole food sources. MannaBAR-TM- was developed partly in response to strong
Associate demand. The Company currently intends to introduce new products each
year, which are expected to contain one or more proprietary components and
complement existing products. The Company believes that its newly enhanced
research and development capabilities will facilitate its ability to develop
these new products.
 
    ATTRACT NEW ASSOCIATES AND ENHANCE ASSOCIATE PRODUCTIVITY.  The Company has
enjoyed significant growth in the number of Associates by leveraging its
operating strengths and creating a business climate which promotes growth in the
number of Associates qualifying for recognition and increases the retention,
motivation and productivity of high-level Associates. The Company plans to
introduce new Associate achievement levels in part to encourage greater
retention, motivation and productivity. In addition, the Company plans to
encourage growth in the number of Presidential Associates, currently the highest
level of achievement attainable by an Associate, by modifying Associate events
and recognition programs.
 
   
    ENTER NEW MARKETS.  In October 1998, the Company opened its Australian
headquarters in St. Leonards, Australia and is further exploring the
possibilities for further expansion in several additional countries. By
employing its flexible operating strategy in the international sector, the
Company believes it will be able to enter new markets in a cost-effective and
efficient manner. In addition, the Company will evaluate the following factors
in its decision to expand into new markets: (i) size of market; (ii) anticipated
demand; and (iii) ease of entry. The Company believes that growth potential
exists in international markets. See "Risk Factors-Risks Associated with
International Expansion."
    
 
PRODUCTS
 
   
    The Company markets a line of quality, proprietary products, including 20
different nutritional products and three topical products. The Company also
offers a variety of sales aids, including enrollment and renewal packs (which
include products), brochures and videotapes which accounted for approximately
24.7% of net sales in 1997. The Company believes its focused product line
contributes to efficient distribution and inventory management.
    
 
    The Company believes that the discovery and use of certain carbohydrates
offers significant potential for nutritional benefits. Healthy bodies, comprised
of many sophisticated components working together, must have 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 glycoproteins, or molecules
found on the surface of all cells, play a key role in all cell-to-cell
communication. The name, glycoprotein, is derived from the molecules'
composition: sugar (glyco) and protein. Because up to 85% of glycoproteins are
composed of specific monosaccharides, the body's need for these carbohydrates is
important.
 
    HARPER'S BIOCHEMISTRY, a leading biochemistry reference source, lists eight
monosaccharides commonly found in human glycoproteins which are known to be
important to the healthy functioning of cell-to-cell communications in the human
body. These monosaccharides are fucose, galactose, glucose,
 
                                       41
<PAGE>
mannose, N-acetylgalactosamine, N-acetylglucosamine, N-acetylneuraminic acid and
xylose, and belong to a universe of approximately 200 monosaccharides found in
nature.
 
    The Company recognized the human body's need for these monosaccharides to
support optimal health. In response, the Company developed and filed a patent
application on Ambrotose-Registered Trademark- Complex, which is directed at
these monosaccharides and their various uses. By filing this patent application,
the Company seeks to establish a proprietary position in the nutritional
supplement market. This proprietary glyconutritional compound,
Ambrotose-Registered Trademark- Complex, is a component of each of the Company's
products.
 
   
    The following chart lists the Company's products as of October 15, 1998.

PRODUCT DEVELOPMENT
 
    The Company's overall product strategy is to develop proprietary nutritional
supplements which capitalize on existing and emerging scientific knowledge and
the growing worldwide interest in alternative healthcare and optimal health. The
Company focuses on bringing new proprietary and, where possible, patentable
products to market that can be developed into new product lines, while expanding
its existing product line. The Company believes it is well positioned to take
advantage of the ability to provide educational information regarding dietary
supplements and the increased development of nutritional supplements and
functional foods resulting from the enactment of DSHEA.
 
    The Company intends to launch new products each year at its corporate
events. Selection of the products developed will be based on the marketability
and proprietary nature of the product, taking into account regulatory
considerations, the availability of components and the existence of data
supporting claims of functionality. To support and validate the proprietary
nature of the Company's product line, appropriate research is conducted under
the direction of the Company's research and development department both before
and after product launch. The Company believes that the completion of its new
laboratory will help to accelerate and improve new product development.
 
    The following chart indicates the year of introduction of each of the
Company's products:

PRODUCT DISTRIBUTION SYSTEM
 
    OVERVIEW.  The foundation of the Company's sales philosophy and distribution
system is network marketing. As with most network marketing systems, the
Company's Associates purchase products for retail sale and personal consumption.
The Company believes network marketing is an effective vehicle to distribute the
Company's products for the following reasons: (i) the benefits of the Company's
products are more readily explained on an individual, educational basis, which
emphasizes the manner in which its products work, and is more direct than the
use of television and print advertisements; (ii) direct sales allow for actual
product testing by a potential consumer; (iii) the impact of Associate and
consumer testimonials is enhanced; and (iv) as compared to other distribution
methods, Associates can provide higher levels of customer service and attention
by, among other things, following up on sales to ensure proper product usage and
customer satisfaction, and encouraging repeat purchases.
 
   
    The Company encourages Associates to enroll new Associates with whom the
Associates may have an ongoing relationship as a family member, friend, business
associate, neighbor or otherwise. To become an Associate of the Company, a
person may enroll as a Preferred Customer and subsequently execute an Associate
Application, sponsor new Associates or purchase a starter pack. Alternatively,
one can become an Associate by purchasing one of the Associate starter packs.
Each starter pack includes some combination of nutritional products, promotional
materials, and free admission to the Company's events. Each pack also allows the
Associate to purchase product at the Company's wholesale price. The components,
purchase price of the pack, and wholesale value of the included items for the
periods for which financial data is presented are detailed in the table below.

    The Company also requires Associates to renew their status each year by
either renewing as a Preferred Customer and continuing to sponsor New Associates
or by purchasing a renewal pack. Prior to June 1998 the Associates renewed at
the $49.00, $229.00 and $568.00 levels. The renewal packs were identical to the
starter packs in the table above sold at the same price. Beginning June 1998 the
Associates renew at the $29.00, $200.00 or $350.00 level. If an Associate chose
not to renew his Associate status he could continue to purchase the Company's
products at the wholesale price and resell the products if he desired; however,
he would not be qualified to earn commissions or bonuses under the Company's
compensation plan.
 
   
    In May 1998 the Company introduced a new starter pack priced at $29.00 which
consists of 15 promotional materials which would cost $14.50 if purchased
separately at their wholesale value, which can also be used to renew Associate
status, if elected.
    
 
   
    Total associate packs sold were 67,530, 117,688, 174,680 and 120,777 for
1995, 1996, 1997 and the nine months ended September 30, 1998 respectively.
Sales of renewal packs were 907, 19,875, 41,219, and 44,157 respectively for the
same periods. The number of starter packs sold were 66,623, 97,813, 133,461, and
76,620 during the respective periods. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations".
    
 
                                       44

    The Company believes that Associates will be more likely to remain with the
Company if they are enrolled with the Company by someone with whom they have an
ongoing relationship. The Company also believes that its network marketing
system will continue to build a base of potential consumers for additional
products. The Company encourages, but does not require, Associates to use the
Company's products, nor does the Company require a person to be an Associate in
order to be a consumer of the Company's products. The Company believes its
network marketing system is particularly attractive to prospective Associates
because of the potential for supplemental income and because Associates are not
required to purchase any inventory, have no account collection issues, have
minimal paperwork requirements and have a flexible work schedule. The sales
efforts of Associates are supported through various means, including
Company-sponsored events held periodically throughout the year.
 
    The effectiveness of direct selling as a distribution channel has been
enhanced in the past decade through advancements in communications, including
telecommunications, and the proliferation of the use of videotape players, fax
machines and personal computers. The Company produces high-quality video tapes
and audio tapes for use in product education, demonstrations and sponsoring
sessions that project a desired image for the Company and its product line. The
Company believes that high quality sales aids play an important role in the
success of Associate efforts. The Company is committed to fully utilizing
current and future technological advances to continue to enhance the
effectiveness of direct selling.
 
    Associates pay for products prior to shipment. The Company carries no
accounts receivable from Associates, except for minor amounts owing to check
returns or other exceptions. Associates pay for products primarily by credit
card, with cash, money orders and checks representing a small portion of all
payments. Associates may automatically order product, applied to a credit card,
on a continuous basis, and receive a discount. Automatic orders accounted for
approximately 36.9% of net sales for the year ended December 31, 1997.
 
    ASSOCIATE DEVELOPMENT.  The Company believes that the key contributing
factors to its long-term growth and success are the recruitment of new
Associates and retention of existing Associates. The Company is active in the
development of Associates, including in the areas of recruitment, support,
motivation and compensation.
 
    The Company primarily relies on current Associates to sponsor new
Associates. The sponsoring of new Associates creates multiple levels in the
network marketing structure. Persons whom an Associate sponsors are referred to
as "downline" or "sponsored" Associates. Once a person becomes an Associate, he
or she is able to purchase products directly from the Company at wholesale
prices for resale to consumers or for personal consumption. The Associate is
also entitled to sponsor other Associates in order to build a network of
Associates and product users.
 
    The Company also relies heavily on existing Associates to train new
Associates, utilizing a new training program for Associates ("Accredited
Training") developed using both the expertise of experienced corporate trainers
and the experience of seasoned Associates. While the Company provides brochures,
magazines and other sales materials, Accredited Training is specially designed
to provide systematic and uniform training to Associates about the Company, its
products, methods of doing business and compensation plan. As of January 1998,
only Associates who have participated in Accredited Training are eligible to
receive remuneration for training other Associates.
 
    The Company makes the needs of its Associates a priority, in accordance with
its stated corporate philosophy. The Company provides a high level of support
services tailored to the needs of its Associates, including motivational
meetings, educational and informative conference calls, automated fax services,
ordering and distribution system, personalized customer service via telephone,
the Internet and e-mail, 24-hour, seven days per week access to certain
information through touch-tone phones and a liberal product return policy. The
Company's support system includes a current database of all Associates and their
upline and downline Associates. The Company also provides business development
materials that
 
                                       45
<PAGE>
the Company believes will increase both product sales and recruitment. The
Company believes that enhancing an Associate's efforts through effective support
mechanisms has been and will continue to be important to the success of the
Company.
 
    The Company currently recognizes Associate performance with four levels of
Associate leadership achievement: Regional; National; Executive; and
Presidential. Each leadership level is vested with the opportunity for
additional compensation ranging from 4% of commissionable sales at the Regional
Director level to 16% of commissionable sales at the Presidential level. The
Company intends to develop additional achievement levels in the future specially
designed to stimulate continued production and downline growth by motivating
Associates at the highest levels. Additionally, the Company intends to expand
its program of Associate recognition to express its appreciation for increased
levels of performance and to further motivate Associates.
 
   
    ASSOCIATE COMPENSATION.  All Associate compensation is paid directly by the
Company and is based on sales of the Company's products, the achievement of
certain leadership levels and the training of other Associates. The Company
offers a compensation plan which combines aspects of two widely-used multi-level
marketing compensation plans. The Company's compensation plan integrates a
single downline, or "unilateral" element, with a multiple downline, or "binary"
element, and adds additional compensation based upon attainment of certain
Associate leadership levels and training performance. The "unilateral" and
"binary" elements of the compensation plan are similar to other multi-level
marketing compensation plans. All commissions are based on wholesale prices.
Associates may, at their discretion, determine the resale price of products
purchased at wholesale. Leadership bonuses pay associates as much as 16% of
commissionable sales as various leadership levels are attained. The compensation
plan includes bonuses or commissions for qualified associates ranging from $20
to $180 earned based on downline growth. Associates who have completed
"accredited training" can receive a commission of $25 for each additional
Associate they train. Bonuses or commissions ranging from $10 to $200 are also
earned on products included in starter or introductory packs. The result of this
"hybrid" structure is to compensate both Associates in the early stages of
building their business and Associates with more established organizations, by
rewarding Associates for breadth as well as depth in their downline
organizations. In addition to the "hybrid" compensation plan, Associates earn
compensation for retail sales of products.
    
 
   
    Based upon its knowledge of other industry-related network marketing
compensation plans, the Company believes that its compensation plan is among the
most financially rewarding plans offered in the industry, with commissions as a
percentage of net sales of 38.5%, 40.7%, 41.0% and 39.8% for 1995, 1996, 1997
and the nine months ended September 30, 1998, respectively.
    
 
    The Company, in configuring its international compensation plans, will not
employ its existing compensation plan outside of the United States and Canada.
In the international sector, the Company intends to use substantially similar
unilateral plans from country to country, which will be tailored to fit the
applicable laws and other considerations governing compensation of Associates in
each country. The Company plans to seamlessly integrate its international
compensation plans across all markets in which the Company's products are, or
will be, sold. This will allow Associates to receive commissions for global
product sales, rather than merely local product sales. The seamless downline
structure will be designed to allow an Associate to build a global network by
creating downlines in international markets. Associates will not be required to
establish new downlines or requalify for higher levels of commissions within
each new country in which they begin to operate. The Company intends to develop
international compensation plans which will be designed to pay approximately the
same percentage compensation as in the United States and which will stimulate
both product sales as well as the development of width and breadth in downline
organizations in accordance with local laws.
 
    MANAGEMENT OF ASSOCIATES.  The Company takes an active role in the
management of its Associates. Many multi-level marketing companies encounter
difficulty with regulatory authorities due to lack of
 
                                       46
<PAGE>
oversight of Associate activities. Any oversight process is complicated by the
fact that Associates are not legally employees of the Company, but are
independent contractors. However, the Company seeks to restrict the statements
and conduct of Associates regarding the Company's business by contractually
binding Associates to abide by the Associate Policies and Procedures (the
"Policies and Procedures") promulgated by the Company. Each Associate receives a
copy of the Policies and Procedures which must be followed in order to maintain
the Associate's status in the organization. Associates are expressly forbidden
from making any representation as to the possible earnings of any Associate,
other than through statements of the Company indicating the range of actual
earnings by all Associates and other required information, prepared in
accordance with applicable law. Associates are also prohibited from creating any
marketing literature that has not been approved by the Company or a qualified
attorney. The Company monitors Associate web sites and Internet conduct on a
regular and continuing basis.
 
    The Company enforces the Policies and Procedures through its disciplinary
procedure, which is instituted through the filing of a complaint against the
Associate, followed by a response from the Associate, an investigation of the
facts, and the presentation of the facts to a committee of corporate managers
not within the Company's compliance department (the "Compliance Department") for
determination. The Compliance Department is also free to evaluate complaints,
and, where the conduct complained of is not within the scope of the Policies and
Procedures, refer the complaint to an Associate Advisory Counsel for
intervention to address Associate ethics. The Compliance Department also has the
discretion to intervene with Associates at a lower level of discipline, while
still creating a record of the possible infraction and educating the Associate
through its practice of issuing warning letters. The Associate is educated as to
the nature of the complaint against him or her, the policy alleged to have been
violated, and then, without a finding of whether the conduct occurred or not, is
asked to confirm in writing that he or she understands the policy in question,
agreeing that he or she will thereafter follow all of the Policies and
Procedures of the Company.
 
    The Compliance Department and the Director of Specialized Information
monitor Company-related meetings at various locations and at corporate events,
generating a "report card" for the presenting Associate, offering critiques and
employing the Associate disciplinary process, where necessary. The Compliance
and Legal Departments, in cooperation with the other departments of the Company,
regularly evaluate Associate conduct and the need for new and revised
rule-making. The Company also tracks Associate compliance intervention and
communication through a system that allows both corporate personnel and
regulatory officials to review details about Associate compliance intervention,
timing and disposition. The Company believes that the compliance program
reflects positively on the Company, helps in the maintenance of Associate ethics
and aids the Company's recruiting activities.
 
   
    PRODUCT RETURN POLICY.  The Company's product return policy provides that
retail customers may return the unused portion of any product to the selling
Associate and receive a full cash refund. Any Associate who provides a refund to
a customer is reimbursed with product by the Company upon providing proper
documentation and the remainder of the product. Historically, product returns
have not been significant. Returns as a percentage of net sales were 0.6%, 1.2%,
1.5% and 1.3% in 1995, 1996, 1997 and the nine month period ended September 30,
1998, respectively.
    
 
INFORMATION TECHNOLOGY AND SYSTEMS
 
    The Company believes that maintaining sophisticated and reliable transaction
processing systems is essential to the long-term success of the Company. The
Company's systems are designed to: (i) reduce the time required to supply an
Associate or customer with the products of the Company; (ii) provide detailed
and customized billing information; (iii) respond quickly to Associate needs and
information requests; (iv) provide detailed and accurate information concerning
qualification and downline activity; (v) provide detailed and customized
Associate commission payments; (vi) support the functions of the Company's
Customer Service Department; and (vii) monitor, analyze and report financial and
operating trends. In order to meet these needs and expand transaction processing
systems to accommodate the
 
                                       47
<PAGE>
Company's expected growth, capital and operating expenditures for information
technology operations and development activities are expected to be
approximately $4 million during 1998.
 
    The suppliers of computer hardware to the Company are Dell Computer
Corporation, Hewlett-Packard Company, Compaq Computer Corporation and Digital
Equipment Corp. ("DEC"). The DEC hardware systems are linked to provide a high
level of availability for critical business applications. The Company believes
the global presence of these suppliers will be an important factor in supporting
the Company's expansion plans.
 
    The Company's financial software was upgraded at the end of 1996 with the
acquisition of a sophisticated financial system, capable of operating on several
platforms. The system exists in a client-server environment, employs a graphical
interface and has a relational and scaleable database to accommodate the need
for business modifications and growth. In addition, the Company has purchased a
decision-support system which interfaces with its financial systems. These
systems, used in tandem, enable the Company to track and analyze financial
information and operations efficiently and effectively, as well as create and
produce custom reports. The Company believes that its computer systems have been
developed and operate using products which are Year 2000 compliant.
 
    The Company believes that its significant investment in software, hardware
and personnel will enable it to (i) respond rapidly to its business needs for
information technology assessment and development, (ii) manage international
growth and its seamless downline structure, and (iii) reduce expenses as a
percentage of sales as revenues increase.
 
PRODUCTION AND DISTRIBUTION
 
    All of the Company's products are manufactured by outside contractors.
Production outsourcing provides the Company with the production capacity
necessary to respond to fluctuations in sales, and significantly limits
investment in capital equipment. In order to meet the Company's needs,
relationships were developed with three large contractors in 1997. With the
increased capacity, the Company believes that it currently has in place the
manufacturers necessary to meet its volume requirements over the next several
years, including expansion into foreign markets. The Company, however, continues
to identify new quality-driven manufacturers to supply the products necessary to
the Company's success. The Company seeks to obtain cost efficiencies by
reviewing, from time to time, pricing considerations and by requiring
competitive bids from various manufacturers meeting its quality and performance
requirements.
 
    The Company currently acquires ingredients solely from suppliers that are
considered by the Company to be the superior suppliers of such ingredients. The
Company believes it has developed dependable alternative sources for all of its
ingredients except Manapol-Registered Trademark- and arabinogalactan, which are
components of the Company's proprietary raw material. The Company believes that,
in the event it is unable to source any ingredients from its current suppliers,
such ingredients could be produced by the Company or replaced with substitute
ingredients. However, any delay in replacing or substituting such ingredients
would have a material adverse effect on the Company's business, results of
operations and financial condition. See "Risk Factors-Reliance on and
Concentration of Outside Manufacturers."
 
    Two ingredients are proprietary to the Company: (i) Ambrotose-Registered
Trademark- Complex, a glyconutritional dietary supplement consisting of a blend
of plant polysaccharides, which is a component of each of the Company's products
and (ii) Dioscorea Complex, a blend of herbal extracts. The Company plans to
bring the blending of all proprietary formulas in-house, further protecting the
confidential nature and high quality standards of its proprietary formulations.
In the meantime, the Company continues to identify high quality sources of
supply for its ingredients. The Company's employees audit all critical contract
vendors and suppliers on a semi-annual basis. See "Risk Factors-Dependence on
Proprietary Ingredient."
 
                                       48

    In January 1998, the Company's Texas distribution operation relocated to a
new $1.3 million, 75,000 square foot facility in Coppell, Texas. The facility
includes an automated pick-to-light system that the Company believes will
enhance productivity and support order volume growth, and is capable of
processing 6,000 orders per shift. The facility also contains a warehouse,
distribution offices and an ingredient mixing area that is expected to be
operational in 1999. The Canadian distribution center is a contract operation
occupying a 6,000 square foot compartment in a 100,000 square foot building
which currently fills approximately 800 orders per day. The Australian
distribution center, located in Botany, Australia, is a contract operation
occupying a 3,000 square feet compartment in a 100,000 square foot building
which can fill approximately 20,000 orders per day.
    
 
    In March 1998, the Company completed construction of its technologically
advanced research and development laboratory that includes gas and liquid
chromatographs and mass spectrometers which will be used to maintain quality
standards, support the Company's research and development commitment in the area
of new herbal complexes, and support the development of new products as well as
its existing product line.
 
GOVERNMENT REGULATION
 
    In addition to regulation of its direct selling activities, the Company, in
both the United States and foreign markets, is or will be subject to and
affected by extensive laws, governmental regulations, administrative
determinations, court decisions and similar constraints (as applicable, at the
federal, state and local levels) including, among other things, regulations
pertaining to (i) the formulation, manufacturing, packaging, labeling,
distribution, importation, sale and storage of the Company's products, (ii)
product claims and advertising (including direct claims and advertising by the
Company as well as claims and advertising by Associates, for which the Company
may be held responsible), (iii) the Company's network marketing system, (iv)
transfer pricing and similar regulations that affect the level of foreign
taxable income and customs duties and (v) taxation of Associates, which in some
instances may impose an obligation on the Company to collect the taxes and
maintain appropriate records. See "Risk Factors-Government Regulation of
Products and Marketing; Import Restrictions."
 
    PRODUCTS.  The formulation, manufacturing, packaging, storing, labeling,
advertising, distribution and sale of the Company's products are subject to
regulation by one or more governmental agencies, including the FDA, the Federal
Trade Commission ("FTC"), the Consumer Product Safety Commission, the Department
of Agriculture, the Environmental Protection Agency and the Postal Service. The
Company's activities are also regulated by various agencies of the states,
localities and foreign countries in which the Company's products are
manufactured, distributed and sold. The FDA, in particular, regulates the
formulation, manufacture, packaging, storage, labeling, promotion, distribution
and sale of foods, dietary supplements and OTC drugs, such as those distributed
by the Company. FDA regulations require the Company and its suppliers to meet
relevant good manufacturing practice ("GMP") regulations for the preparation,
packing and storage of drugs. The FDA has published a Notice of Advanced Rule
Making for GMPs for dietary supplements, but it has not yet issued a proposal.
 
    DSHEA revised the provisions of the Federal Food, Drug and Cosmetic Act
("FFDCA") concerning the composition and labeling of dietary supplements and,
the Company believes, is generally favorable to the dietary supplement industry.
The legislation creates a new statutory class of "dietary supplements." This new
class includes vitamins, minerals, herbs, amino acids and other dietary
substances for human use to supplement the diet, and the legislation
grandfathers, with certain limitations, dietary ingredients that were on the
market before October 15, 1994. A dietary supplement which contains a new
dietary ingredient (I.E., one not on the market before October 15, 1994) will
require evidence that the supplement contains only ingredients that have been
present in the food supply in a certain form or evidence of a history of use or
other evidence of safety establishing that it is reasonably expected to be safe.
Manufacturers of dietary supplements which make a "statement of nutritional
support," which is a statement describing certain types of product performance
characteristics, must have substantiation that
 
                                       49
<PAGE>
the statement is truthful and not misleading, must make a disclaimer in the
statement itself and must notify the FDA of the statement no later than 30 days
after it is first made.
 
    The majority of the products marketed by the Company are classified as
dietary supplements under the FFDCA. In September 1997 the FDA issued
regulations governing the labeling and marketing of dietary supplement products.
The regulations cover: (i) the identification of dietary supplements and their
nutrition and ingredient labeling; (ii) the terminology to be used for nutrient
content claims, health content claims and statements of nutritional support;
(iii) labeling requirements for dietary supplements for which "high potency" and
"antioxidant" claims are made; (iv) notification procedures for statements on
dietary supplements; and (v) premarket notification procedures for new dietary
ingredients in dietary supplements. The notification procedures became effective
in October 1997, while the new labeling requirements will not become effective
until March 23, 1999. The Company will be required to revise a substantial
number of its product labels to reflect the new requirements prior to the 1999
effective date, although the Company does not expect the cost or impact of such
actions to be material. In addition, the Company will be required to continue
its ongoing program of securing substantiation of its product performance
claims, and of notifying the FDA of certain types of performance claims made for
its products. The Company's substantiation program involves compiling and
reviewing the scientific literature pertinent to the ingredients contained in
the Company's products.
 
    In addition, in certain markets, including the United States, claims made
with respect to dietary supplement, personal care or other products of the
Company may change the regulatory status of the products. In the United States,
for example, it is possible that the FDA could take the position that claims
made for certain of the Company's products make those products new drugs
requiring preliminary approval or place those products within the scope of an
FDA OTC drug monograph. OTC monographs prescribe permissible ingredients and
appropriate labeling language, and require the marketer or supplier of the
products to register and file annual drug listing information with the FDA. Of
the products sold by the Company, only Emprizone-Registered Trademark- is
labeled as an OTC monograph drug, and the Company believes that it is in
compliance with the applicable monograph. In the event that the FDA asserted
that product claims for other products caused them to be new drugs or fall
within the scope of OTC monographs, the Company would be required either to file
a New Drug Application, comply with the applicable monographs or change the
claims made in connection with the products.
 
    Dietary supplements are subject to the Nutrition, Labeling and Education Act
("NLEA"), and regulations promulgated thereunder, which regulates health claims,
ingredient labeling and nutrient content claims characterizing the level of a
nutrient in the product. NLEA prohibits the use of any health claim for dietary
supplements, unless the health claim is supported by significant scientific
agreement and is pre-approved by the FDA.
 
    In foreign markets, prior to commencing operations and prior to making or
permitting sales of its products in the market, the Company may be required to
obtain an approval, license or certification from the country's ministry of
health or comparable agency. Where a formal approval, license or certification
is not required, the Company will nonetheless seek a favorable opinion of
counsel regarding the Company's compliance with applicable laws. Prior to
entering a new market in which a formal approval, license or certificate is
required, the Company will work with local authorities in order to obtain the
requisite approvals, license or certification. The approval process generally
requires the Company to present each product and product ingredient to
appropriate regulators and, in some instances, arrange for testing of products
by local technicians for ingredient analysis. Such approvals may be conditioned
on reformulation of the Company's products or may be unavailable with respect to
certain products or certain ingredients. The Company must also comply with
product labeling and packaging regulations that vary from country to country.
 
    The FTC, which exercises jurisdiction over the marketing practices and
advertising of all the Company's products, has in the past several years
instituted enforcement actions against several dietary
 
                                       50
<PAGE>
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. In addition,
the FTC has increased its scrutiny of the use of testimonials, which are
utilized by the Company. Importantly, the FTC requires substantiation for
product claims at the time such claims are first made. A failure to have
substantiation when product claims are first made violates the Federal Trade
Commission Act. While the Company has not been the subject of FTC enforcement
action for the advertising of its products, there can be no assurance that the
FTC will not question the Company's advertising or other operations in the
future.
 
    Through its manuals, seminars and other training materials and programs, the
Company attempts to educate Associates as to the scope of permissible and
impermissible activities in each market. The Company also investigates
allegations of Associate misconduct. However, Associates are generally
independent contractors, and the Company is not able to monitor directly all
Associate activities. As a consequence, there can be no assurance that
Associates comply with applicable regulations.
 
    The Company is unable to predict the nature of any future laws, regulations,
interpretations or applications, nor can it predict what effect additional
governmental regulations or administrative orders, when and if promulgated,
would have on its business in the future. They could, however, require the
reformation of certain products not able to be reformulated, imposition of
additional recordkeeping requirements, expanded documentation of the properties
of certain products, expanded or different labeling and scientific
substantiation regarding product ingredients, safety or usefulness. Any or all
of such requirements could have a material adverse effect on the Company's
business, results of operations and financial condition.
 
    NETWORK MARKETING SYSTEM.  The Company's network marketing system, which
includes its compensation plan, is subject to a number of federal and state
statutes and regulations administered by the FTC and various state agencies. The
legal requirements applicable to network marketing organizations are generally
directed at ensuring that product sales are ultimately made to consumers and
that advancement within such organizations be based on sales of the
organizations' products rather than compensation derived principally from the
recruitment of additional associates, investments in the organizations or other
non-retail sales related criteria. For instance, in certain markets there are
limits on the extent to which Associates may earn royalties on sales generated
by Associates that were not directly sponsored by the Associate. Where required
by law, the Company will obtain regulatory approval of its network marketing
system or, where such approval is not required, the favorable opinion of local
counsel as to regulatory compliance. The FTC regulates trade practices related
to network marketing systems.
 
    Under a consent decree entered into in February 1997 as a result of
negotiation with the Attorney General of the State of Michigan, the Company has
agreed to monitor product purchases by its Associates in Michigan. The purpose
of the monitoring is to identify and correct any instances of coerced sales. The
Company also conducts a number of random audits of Associates in Michigan for
evidence of stockpiling. To date, the Company has not found evidence of coerced
sales or stockpiling by its Associates in Michigan, and the Company's commission
policies are designed to provide no incentive or reward to Associates for
engaging in such activities.
 
    In Canada, the regulation of the Company's network marketing system is
subject to both federal and provincial law. Under Canada's Federal Competition
Act (the "Competition Act"), the Company must ensure that any representations
relating to Associate compensation to a prospective Associate constitute fair,
reasonable and timely disclosure and that it meets other legal requisites of the
Competition Act. The Company's compensation plan has been reviewed by the
appropriate Canadian authorities. In addition, all Canadian provinces and
territories other than Ontario have legislation requiring the registration or
licensing of the Company as a direct seller within that jurisdiction. Licensing
is designed to maintain the standards of the direct selling industry and to
protect the consumer. Some provinces require that both
 
                                       51
<PAGE>
the Company and its Associates be licensed. The Company currently holds the
requisite provincial or territorial direct sellers' licenses.
 
   
    In Australia, the Company's network marketing system is subject to both
federal and state regulation. The compensation plan employed in Australia is a
unilateral plan, which is designed and disclosed to meet the requisites of
applicable state requirements and the requirements of the Trade Practices Act.
Business and solicitation practices of the Company and its associates are
regulated by state law and the Trade Practices Act. Claims and representations
relating to products are regulated by both the Trade Practices Act and the
Therapeutic Goods Act.
    
 
    OTHER REGULATIONS.  The Company is also subject to a variety of other
regulations in various foreign markets, including regulations pertaining to
social security assessments and value added taxes, employment and severance pay
requirements, import/export regulations and antitrust issues. As an example, in
many markets the Company is substantially restricted in the amount and types of
rules and termination criteria that it can impose on Associates without causing
social security assessments to be payable by the Company on behalf of such
Associates and without incurring severance obligations to terminated Associates.
In some countries, the Company may be subject to such obligations in any event.
See "Risk Factors-Government Regulation of Products and Marketing; Import
Restrictions."
 
    In certain countries, including the United States, the Company may also be
affected by regulations applicable to the activities of its Associates because
in some countries the Company is, or regulators may assert that the Company is,
responsible for its Associates' conduct, or such regulators may request or
require that the Company take steps to ensure its Associates' compliance with
regulations. The types of regulated conduct include, among other things,
representations concerning the Company's products, income representations made
by the Company or Associates and sales of products in markets in which such
products have not been approved, licensed or certified for sale. In certain
markets, including the United States, it is possible that improper product
claims by Associates could result in the Company's products being reviewed or
re-reviewed by regulatory authorities and, as a result, being classified or
placed into another category as to which stricter regulations are applicable. In
addition, certain labeling changes might be required.
 
    COMPLIANCE PROCEDURES.  The Company, its products and its network marketing
system are subject, both directly and indirectly through Associates' conduct, to
numerous federal, state and local regulations both in the United States and
foreign markets. Beginning in 1997, the Company began to institute formal
regulatory compliance measures by developing a system to identify specific
complaints against Associates and to remedy any violations by Associates through
appropriate sanctions, including warnings, suspensions and, when necessary,
terminations. At the same time the Company instituted internal policies for
compliance with FDA and FTC rules and regulations. See "-Product Distribution
System-Management of Associates."
 
    In order to comply with regulations that apply to both the Company and its
Associates, the Company continues to conduct research into the applicable
regulatory framework prior to entering any new market to identify all necessary
licenses and approvals and applicable limitations on the Company's operations in
that market. The Company will devote substantial resources to obtaining such
licenses and approvals and bringing its operations into compliance with such
limitations. The Company will also research laws applicable to Associate
operations and revise or alter its business system, compensation plan, Associate
requirements and other materials and programs to provide Associates with
guidelines for operating a business, marketing and distributing the Company's
products and similar matters, as required by applicable regulations in each
market. However, the Company is not able to fully monitor its Associates
effectively to ensure that they refrain from distributing the Company's products
in countries where the Company has not commenced operations, and the Company
does not devote significant resources to such monitoring.

COMPETITION
 
    The nutritional supplements industry is large and intensely competitive. The
Company competes directly with companies that manufacture and market nutritional
products in each of the Company's product lines, including General Nutrition
Companies, Inc., Solgar Vitamin and Herb Company, Inc., Twinlab Corporation and
Weider Nutrition International, Inc. Many of the Company's competitors in the
nutritional supplements market have longer operating histories and greater name
recognition and financial resources than the Company. In addition, nutritional
supplements can be purchased in a wide variety of distribution channels. While
the Company believes that consumers appreciate the convenience of ordering
products from home through a sales person, the buying habits of many consumers
accustomed to purchasing products through traditional retail channels are
difficult to change. The Company's product offerings in each product category
are also relatively small compared to the wide variety of products offered by
many other nutritional product companies.
 
    The Company also competes in the nutritional supplements market and for new
associates with other retail, multi-level marketing and direct selling companies
in the nutritional supplements industry by emphasizing the proprietary nature,
value, proprietary components and the quality of the Company's products and the
convenience of the Company's distribution system. The Company also competes with
other direct selling organizations, many of which have longer operating
histories and greater name recognition and financial resources than the Company.
They include Amway Corporation, Nu Skin Enterprises, Inc., Body Wise
International, Inc., ENVION International, Herbalife International, Inc., Enrich
International, Rexall Showcase International, Forever Living Products, Inc. and
Melaleuca, Inc. The Company competes for new Associates on the basis of its
compensation plan and its proprietary and quality products. The Company believes
that many more direct selling organizations will enter the marketplace as this
channel of distribution expands over the next several years. The Company also
competes for the commitment of its Associates. Given that the pool of
individuals interested in direct selling tends to be limited in each market, the
potential pool of Associates for the Company's products is reduced to the extent
other network marketing companies successfully recruit these individuals into
their businesses.
 
EMPLOYEES
 
   
    As of September 30, 1998, the Company employed approximately 265 people, ten
of whom occupy executive positions. This number does not include Associates, who
are independent contractors rather than employees of the Company. A limited
number of employees are also Associates, having enrolled prior to a policy
instituted in May 1997, which precludes any further enrollment by employees as
Associates. The Company only allows employees to be Associates if they have
disclosed their status to the Company and have executed an agreement not to use
their employment status to assist in building their business as an Associate.
The Company is currently evaluating ways in which existing employee-Associates
can be fairly treated or compensated for the extinguishment of their rights as
Associates. The Company's employees are not unionized, and the Company believes
its relationship with its employees is good.
    
 
PROPERTIES
 
   
    The Company leases approximately 110,000 square feet in Coppell, Texas for
its headquarters. The Company leases 75,000 square feet in Coppell, Texas for
its warehouse and distribution center. Each of the leases is for a term of 10
years, expiring in January 2007 and January 2008, respectively. The Company also
leases approximately 9,000 square feet in St. Leonards, Australia for its
Australian headquarters. The lease is for a term of five years, expiring in
August 2003.

LEGAL PROCEEDINGS
 
    The Company, in the ordinary course of business, is involved in various
legal proceedings. The Company does not believe the outcome of any of these
proceedings, other than those described below, would have a material adverse
effect on the Company's business, results of operations or financial condition.
 
   
    The Company received a demand letter (the "Demand Letter") from Dr. Joe
Glickman, Jr. an Associate of the Company, alleging that the Company had, among
other things, breached various contracts, agreements and promises, and stating
an intention to pursue these claims in the United States District Court for
Montana. In March 1998, the Company commenced an arbitration proceeding against
Dr. Glickman individually and as trustee of Dr. Joe Glickman, Jr. Phyto Trust
d/b/a/ Alotek (collectively, "Alotek"), for the recovery of certain funds and
the cancellation of Associate positions claimed by Alotek. Based upon Alotek's
refusal to arbitrate and the Demand Letter, the Company sought and obtained a
temporary restraining order in Texas state district court restraining Alotek
from filing an action against the Company in any other court or forum pending
the court's ruling on whether Alotek's claims were subject to commercial
arbitration in Dallas, Texas. Thereafter, Alotek removed the state court action
to Federal District Court in Dallas, Texas ("Dallas Court"), and concurrently
commenced a suit in Federal District Court in Montana ("Montana Court"). In May
1998, the Company also received a demand letter from Alotek threatening to
institute a "class action" on behalf of all of the Company's Associates in
federal court against the Company for alleged fraud and misrepresentation. In
September 1998, the Dallas Court entered an order referring the case to
arbitration, and thereafter administratively closed the case. The order of the
Dallas Court was appealed by Glickman to the Fifth Circuit Court of Appeals in
October 1998. In October 1998, the Montana Court dismissed the case of Glickman
in its entirety. The arbitration is in its earliest stages and discovery has not
yet begun. The Company believes that Alotek's claims are without merit and has
sought declaratory relief to that effect. The Company further believes that it
has valid defenses to all allegations raised by Alotek. Nevertheless, an adverse
resolution of this matter would have a material adverse effect on the Company's
business, results of operations and financial condition.
    
 
    In October 1997, the Company filed an objection to the issuance of a
registered trademark to IntraCell Nutrition, Inc., which had filed a trademark
application for the name, "Manna." The Company contended in its objection, among
other things, that "Manna" is a general descriptor often applied to nutritional
products, and accordingly, is not entitled to trademark protection. The Company
therefore believes that there is a substantial likelihood that the Company will
prevail in its objection to the granting of the tradename.

STOCK OPTION PLANS
 
    1997 STOCK OPTION PLAN.  The 1997 Stock Option Plan was adopted on May 14,
1997 by the Board of Directors of the Company and approved by the shareholders
of the Company on the same date. The 1997 Stock Option Plan is intended to
encourage investment by the officers, employees, non-employee directors and
consultants of the Company in shares of Common Stock, thus creating in such
persons an increased interest in and greater concern for the welfare of the
Company.
 
    Options granted under the 1997 Stock Option Plan may either be options that
qualify ("Incentive Stock Options") or options that do not qualify for treatment
as Incentive Stock Options under Section 422 of the Internal Revenue Code of
1986, as amended (the "Code").
 
   
    Incentive Stock Options may be granted under the 1997 Stock Option Plan to
any person who is an officer or other employee (including officers and employees
who are also directors) of the Company or any parent or subsidiaries that may
exist in the future. Non-qualified options may be granted to consultants or
non-employee directors of the Company. The exercise price of Incentive Stock
Options must be at least the fair market value of a share of Common Stock on the
date of grant. A total of 2,000,000 shares of Common Stock have been reserved
for issuance upon the exercise of options granted or to be granted under the
1997 Stock Option Plan. As of September 30, 1998, options to purchase 2,000,000
shares of Common Stock were outstanding, with a weighted average exercise price
of $2.75 per share, none of which were vested or exercisable at such date and
1,600,000 of which will become vested and exercisable
    
 
                                       59
<PAGE>
   
90 days after the effective date of the Prospectus and 400,000 of which will
become vested and exercisable ratably over a three year period. No shares remain
available for future option grants under the 1997 Stock Option Plan.
    
 
    The 1997 Stock Option Plan provides that until such time as shares of Common
Stock are registered under Section 12 of the Exchange Act it is to be
administered by the Board of Directors and, after such registration, by the
Option Committee. The Option Committee will consist of at least two, but not
more than three, "Non-Employee Directors" as such term is defined in Rule 16b-3
promulgated under the Exchange Act. The Option Committee will have full and
final authority in its discretion, subject to the 1997 Stock Option Plan's
provisions, to determine, among other things, (i) the individuals to whom
options shall be granted, (ii) whether the option granted shall be an Incentive
Stock Option or a non-qualified stock option, (iii) the number of shares of
Common Stock covered by each option, (iv) the time or times at which options
will be granted, (v) the option vesting schedule, (vi) the exercise price of the
options and (vii) the duration of the options granted. The Option Committee will
also have the power to construe and interpret the 1997 Stock Option Plan and
make certain determinations and take certain other actions deemed necessary or
advisable for the proper administration of the 1997 Stock Option Plan. The 1997
Stock Option Plan may be amended, supplemented, suspended or terminated by the
Board of Directors at any time without the approval of the shareholders of the
Company, subject to certain exceptions, provided, however, that any such action
may not affect options previously granted under the 1997 Stock Option Plan.
 
   
    1998 STOCK OPTION PLAN.  The 1998 Stock Option Plan was adopted by the Board
of Directors on April 8, 1998 and was amended on September 4, 1998 to increase
the number of shares reserved for issuance. The 1998 Stock Option Plan is
intended to encourage investment by the officers and employees of the Company in
shares of Common Stock, thus creating in such persons an increased interest in
and greater concern for the welfare of the Company.
    
 
   
    Options granted under the 1998 Stock Option Plan shall be Incentive Stock
Options. Incentive Stock Options may be granted under the 1998 Stock Option Plan
to any person who is an officer or other employee (including officers and
employees who are also directors) of the Company or any parent or subsidiaries
that may exist in the future. The exercise price of Incentive Stock Options must
be at least the fair market value of a share of Common Stock on the date of
grant. Under the 1998 Stock Option Plan, as originally adopted, a total of
500,000 shares of Common Stock were reserved for issuance upon the exercise of
options granted or to be granted under the 1998 Stock Option Plan; the amendment
to the 1998 Stock Option Plan increased this to 1,000,000. As of the date of
this Prospectus, options to purchase 243,000 shares of Common Stock were
outstanding with an exercise price of $8.00 per share, none of which were vested
or exercisable at such date and all of which will become vested and exercisable
ratably over a three year period.
    
 
    The 1998 Stock Option Plan provides that it is to be administered by the
Board of Directors or by an Option Committee appointed by the Board of Directors
and consisting of at least two "Non-Employee Directors" as such term is defined
in Rule 16b-3 promulgated under the Exchange Act. The Option Committee will have
the authority, in its discretion, subject to the 1998 Stock Option Plan's
provisions, to (i) grant Incentive Stock Options, in accordance with Section 422
of the Code; (ii) determine, upon review of relevant information and in
accordance with the 1998 Stock Option Plan, the fair market value of the Common
Stock; (iii) determine the exercise price per share of options to be granted;
(iv) determine the employees to whom, and the time or times at which, options

interpret the 1998 Stock Option Plan; (vi) prescribe, amend and rescind rules
and regulations relating to the 1998 Stock Option Plan; (vii) determine the
terms and provisions of each option granted; (viii) accelerate or defer (with

administration of the 1998 Stock Option Plan. The 1998 Stock Option Plan may be
amended or terminated by the Board of Directors or the Option Committee at any
time without the approval of the shareholders of the Company, subject to certain
exceptions.
 
MANAGEMENT BONUS PLAN
 
    The executive officers and certain other members of corporate management are
eligible to receive bonuses in addition to their base salaries. The bonus plan
is based upon the attainment by management of certain financial goals of the
Company. The amount of the bonuses paid pursuant to the bonus plan, prior to
this offering, has been reviewed and approved by the Board of Directors. After
this offering, amounts to be paid under the bonus plan will be reviewed and
approved by the Compensation Committee.
 
401(K) PLAN
 
    Effective May 9, 1997, the Company adopted a 401(k) Pre-tax Savings Plan
(the "401(k) Plan"). All employees who have been employed by the Company for at
least 90 days at the beginning of a quarter and are at least 21 years of age are
eligible to participate. Employees may contribute to the 401(k) Plan up to 15%
of their current compensation, subject to a statutorily prescribed annual limit.
The 401(k) Plan provides that the Company will make regular matching
contributions to the 401(k) Plan in the amount of $0.25 for each $1.00
contributed by the participant, up to 6% of the participant's annual
compensation, including overtime. The 401(k) Plan also provides that the Company
may determine to make a discretionary profit-sharing contribution to the plan
each year based upon the Company's profitability for that year. Employee
contributions and the Company's matching contributions are paid to a corporate
trustee and invested in various funds at the discretion of the participant. The
Company's contribution vests over five years or earlier upon attainment of
retirement at age 65, retirement for disability or upon death of the employee or
termination of the 401(k) Plan. Distributions may also be made in the case of a
financial hardship. Distributions may be made in the form of a lump sum. The
401(k) Plan is intended to qualify under Section 401 of the Code, so that
contributions made by employees or by the Company to the 401(k) Plan, and income
earned on such contributions, are not taxable to employees until withdrawn from
the 401(k) Plan. As of the date of this Prospectus, the Company has not made any
profit-sharing contributions to the 401(k) Plan.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
    During 1997 the Company had no compensation committee or other committee of
the Board of Directors performing similar functions. Decisions concerning
compensation of executive officers were made by the Board of Directors, which
included Charles E. Fioretti, Samuel L. Caster, Patrick D. Cobb and William C.
Fioretti, who was the Chief Scientific Officer and a director of the Company
until November 1997. Charles E. Fioretti and William C. Fioretti are cousins. It
is contemplated that the Board of Directors will establish the Compensation
Committee, consisting solely of independent directors, subsequent to
consummation of this offering.

                              CERTAIN TRANSACTIONS
 
PARTNERSHIP TRANSACTIONS
 
    Prior to June 1, 1997, certain shareholders of the Company (the "Partners")
directly owned all of the limited partnership interests in three limited
partnerships: Beta M. Partners, Ltd. ("Beta"), Eleven Point Partners, Ltd.
("Eleven Point") and Power Three Partners, Ltd. ("Power Three"). All of the
limited partnership interests in Beta were owned by Charles E. Fioretti,
Chairman of the Board and Chief Executive Officer of the Company, Samuel L.
Caster, President and director of the Company, and William C. Fioretti, who at
the time was a director of the Company. Messrs. Charles E. Fioretti, Samuel L.
Caster and William C. Fioretti also owned all of the limited partnership
interests in Power Three. The limited partnership interests in Eleven Point were
owned equally by four other shareholders of the Company, including Patrick D.
Cobb, Chief Financial Officer and Secretary, and currently a director, of the
Company. The limited partnership interests in another limited partnership,
Dynamic Eight Partners, Ltd. ("Dynamic" and, collectively with Power Three, Beta
and Eleven Point, the "Partnerships") were all owned by Power Three and Eleven
Point. The corporate general partners of each of the Partnerships were also
owned and controlled by Messrs. Charles E. Fioretti, Samuel L. Caster and
William C. Fioretti.
 
    The Partnerships were formed in 1994 to achieve certain tax efficiencies and
to protect certain of the Company's proprietary rights. In December 1994, the
Company transferred certain of its rights and interests in intellectual property
and the Company's right to use the trademark "Manapol-TM-," to Beta. The Company
then entered into a 17-year agreement to pay Beta a royalty based on the
Company's sales volume for the use of the intellectual property and trademark.
During 1995, 1996 and 1997, the Company, under this royalty agreement, incurred
expenses of approximately $979,000, $2,554,000 and $1,780,000, respectively.
Also in December 1994, the Company transferred certain marketing rights to
Dynamic. The Company paid Dynamic a commission, based on a specified sales
volume, in exchange for marketing and consulting services. During 1995, 1996 and
1997, the Company, under its marketing agreement with Dynamic, expensed
approximately $1,395,000, $3,295,000 and $2,275,000, respectively, for
consulting fees.
 
    On June 1, 1997, the Company entered into a merger agreement with the
corporate general partners of the Partnerships, Eight Point Services, Inc.,
Triple Gold Business, Inc., Five Small Fry, Inc. and Beta Nutrient Technology,
Inc. (collectively, the "General Partners"). Pursuant to the merger agreement,
the General Partners were merged with and into the Company, and the issued and
outstanding shares of common stock of each such entity were converted into the
right to receive a certain number of shares of the Company's Common Stock. On
the same date, the Company entered into an exchange agreement among the Company
and the Partners, pursuant to which the Company acquired all of the Partners'
limited partnership interests in the Partnerships in exchange for Common Stock.
As a result of these transactions, an aggregate of 10,000,000 shares of Common
Stock were issued to the Partners, including 3,094,946, 3,094,946, 2,867,284 and
235,706 shares issued to Messrs. William C. Fioretti, Samuel L. Caster, Charles
E. Fioretti and Patrick D. Cobb, respectively.
 
INCENTIVE COMPENSATION AGREEMENTS
 
    In 1994, the Company entered into incentive compensation agreements with
Charles E. Fioretti, the Chairman of the Board and Chief Executive Officer of
the Company, which was provided in lieu of ownership interests in the
Partnerships, Ray Robbins, a shareholder of the Company, which was provided in
part in lieu of ownership interests in the Partnerships, and certain other
employees of the Company. These incentive compensation agreements required the
Company to compensate such shareholders and employees based on the Company
achieving specified monthly sales volumes and certain levels of monthly growth
in the number of new Associates. Pursuant to these agreements, during 1995, 1996
and 1997, the Company paid Mr. Fioretti approximately $21,196, $96,522 and
$93,753, respectively, and, during 1995, 1996 and 1997, the Company paid Mr.
Robbins approximately $144,985, $510,996 and $466,603, respectively. In May and
June 1997, the Company terminated the incentive compensation agreements and
issued 227,662 shares of Common Stock to Mr. Fioretti, 607,333 shares of Common
Stock to Mr. Robbins and an aggregate of 1,192,576 shares of Common Stock to the
other employees in exchange for the termination of their incentive compensation
agreements. In March 1998, the Company
 
                                       62
<PAGE>
terminated the remaining incentive compensation agreement and issued 74,167
shares of Common Stock to an employee in exchange for the termination of such
agreement.
 
LOANS TO OFFICERS
 
    Pursuant to an oral agreement to advance certain officers monies for the
payment of taxes due in connection with the cancellation of their incentive
compensation agreements, on December 31, 1997, the Company made loans of
$162,052 to Dr. Bill H. McAnalley, Vice President of Research and Product
Development of the Company, and of $121,782 to Peter E. Hammer, Vice President
of New Business and International Development of the Company. The loans bear no
interest and are due upon the earlier of December 31, 1998 or the date of a
public offering of the Common Stock, whichever is first to occur. The loans are
secured by shares of Common Stock owned by the shareholders and stock powers
have been executed allowing the Company to transfer such shares in the event the
loans are not repaid.
 
TRANSACTIONS WITH MULTI-VENTURE PARTNERS, LIMITED
 
    In July 1997, in exchange for $10.00 and the agreement of Mr. Chris T.
Sullivan to serve on the Board of Directors, the Company issued Multi-Venture
Partners, Limited, an investment partnership formed by Mr. Sullivan and two
other partners ("Multi-Venture"), an option to purchase 100,000 shares of Common
Stock at an exercise price of $2.00 per share. In addition, in July 1997,
Messrs. Charles E. Fioretti, Samuel L. Caster and William C. Fioretti sold an
aggregate of 399,000 shares of Common Stock to Multi-Venture for an aggregate
consideration of $798,000 ($2.00 per share).
 
CION, LTD. AGREEMENT
 
    In October 1995, certain shareholders of the Company, including Charles E.
Fioretti, William C. Fioretti, Samuel L. Caster, Patrick D. Cobb and Gary L.
Watson, formed Cion, Ltd. ("Cion"). The Company transferred to Cion its
exclusive international rights to market, sell, manufacture and distribute the
Company's products, excluding the United States, Canada and Mexico. The rights
conferred to Cion under the agreement also included the right to relicense the
rights conferred in various international territories. In return, Cion was to
pay the Company royalties based on future sales plus a 1% ownership of Cion.
During 1995, Cion did not record any sales and in late 1995, Cion ceased
operations. In May 1996, Cion transferred all of its rights and agreements to
Mannatech, Ltd., an Isle of Man corporation, 99% owned by certain employees and
shareholders of the Company and 1% owned by the Company. On January 1, 1997,
Mannatech, Ltd. ceased operations and transferred all of its exclusive
international rights to market, sell, manufacture and distribute the Company's
products back to the Company, exclusive of certain licenses covering a number of
Far Eastern countries which were granted by Cion.
 
LOANS TO AGRITECH LABS, INC.
 
    During 1996 and 1997, the Company made advances to Agritech Labs, Inc. and
Agritech Technology, Ltd. (together "Agritech") in the aggregate amount of
approximately $918,000. Over 90% of the capital stock of Agritech is owned by
William C. Fioretti, Charles E. Fioretti, Samuel L. Caster and Patrick D. Cobb.
On August 31, 1997, due to concerns about the ability of Agritech to repay the
loans, each of Messrs. William C. Fioretti, Charles E. Fioretti, Samuel L.
Caster and Patrick D. Cobb and another shareholder of both Agritech and the
Company assumed the obligations of Agritech owed to the Company and issued
individual promissory notes to the Company representing the aggregate amount of
approximately $918,000. Each of the promissory notes bears interest at six
percent per annum and is payable on the earlier of December 31, 1998 or the date
that the maker sells Common Stock in an initial public offering of the Company's
securities. The principal amount outstanding under the notes issued by each of
Messrs. William C. Fioretti, Charles E. Fioretti and Samuel L. Caster is
approximately $275,400 and the principal amount outstanding under the note made
by Mr. Patrick D. Cobb is approximately $45,900. Each of Messrs. William C.
Fioretti, Charles E. Fioretti, Samuel L. Caster and Patrick D. Cobb will repay
to the Company all amounts owing under their respective notes with proceeds
received by them in this offering as Selling Shareholders.

Common Stock are entitled to share ratably in the net assets of the Company upon
liquidation after payment or provision for all liabilities. The holders of
Common Stock have no preemptive rights to purchase shares of stock in the
Company. Shares of Common Stock are not subject to any redemption provisions and
are not convertible into any other securities of the Company. All outstanding
shares of Common Stock are, and the shares of Common Stock to be issued by the
Company pursuant to this offering will be, upon payment therefor, fully paid and
nonassessable.
 
   
PREFERRED STOCK
    
 
    The Board of Directors may from time to time authorize the issuance of one
or more classes or series of Preferred Stock without shareholder approval.
Subject to the provisions of the Articles and limitations prescribed by law, the
Board of Directors is authorized to change the number of shares constituting any
series and fix and determine the designation and preferences, limitations and
relative rights, including voting rights, of the shares of any series of
Preferred Stock so established, in each case without any action or vote by the
shareholders. The Company has no current plans to issue any shares of Preferred
Stock of any class or series.
 
    One of the effects of undesignated Preferred Stock may be to enable the
Board of Directors to discourage an attempt to obtain control of the Company by
means of a tender offer, proxy contest, merger or otherwise, and thereby protect
the Company's management. The issuance of Preferred Stock pursuant to the Board
of Directors' authority described above may adversely affect the rights of the
holders of Common Stock. For example, Preferred Stock issued by the Company may
rank senior to the Common Stock as to dividend rights, liquidation preference or
both, may have full or limited voting rights and may be convertible into shares
of Common Stock. Accordingly, the issuance of shares of Preferred Stock may
discourage bids for the Common Stock or may otherwise adversely affect the
trading price of the Common Stock.
 
WARRANT SHARES
 
    On May 1, 1997, pursuant to an agreement with a consultant, the Company
issued a warrant (the "Warrant") exercisable for 475,015 shares of Common Stock
(the "Warrant Shares") at an exercise price of $1.35 per share. The exercise
price and the number of shares issuable upon exercise of the Warrant are subject
to adjustment upon the occurrence of certain events, including (i) the issuance
of Common Stock as a dividend on shares of Common Stock, (ii) subdivisions or
combinations of the Common Stock, (iii) the issuance of rights or warrants to
purchase the Common Stock for less than the market price or
 
                                       66
<PAGE>
(iv) the distribution of evidences of indebtedness or assets to the holder of
Common Stock or similar events. A holder of the Warrant is not entitled to any
voting, dividend or other rights as a shareholder of the Company. The Warrant
expires upon the earlier to occur of May 1, 2003 or 36 months after the
registration of the Warrant Shares.
 
   
    Holders of Warrant Shares are entitled to certain registration rights for
such Warrant Shares, including piggyback and demand registration rights. If the
Company proposes to register securities under the Securities Act, the holders of
Warrant Shares may require the Company, subject to certain volume and other
limitations, to include all or any portion of such Warrant Shares in such
registration at the Company's expense. Pursuant to such registration rights, a
minimum of 17,031 and a maximum of 475,015 shares are being offered hereby. In
addition, on two occasions during the term of the Warrant, holders of a majority
of the Warrant Shares (in the event any part of the Warrant is transferred) can
require the Company to file a registration statement under the Securities Act
covering all or any part of the Warrant Shares. The expense of the registration
will be paid by the Company only with respect to the first demand registration.
    
 
CERTAIN EFFECTS OF AUTHORIZED BUT UNISSUED STOCK
 
   
    Under the Articles, upon completion of this offering there will be a minimum
of 74,223,247 shares and a maximum of 75,381,231 shares of Common Stock
available for future issuance without shareholder approval, depending on the
actual amount sold in this offering. These additional shares may be utilized for
a variety of corporate purposes, including future public offerings to raise
additional capital or facilitate acquisitions. The Company does not currently
have any plans to issue additional shares of Common Stock, other than shares of
Common Stock that may be issued upon the exercise of options and Warrants that
have been granted or may be granted in the future.
    
 
SPECIAL PROVISIONS OF THE ARTICLES, THE BYLAWS AND TEXAS LAW
 
    The Texas Miscellaneous Corporation Laws Act (the "Texas Miscellaneous
Laws") authorizes corporations to limit or eliminate the personal liability of
directors to corporations and their shareholders for monetary damages for breach
of their fiduciary duty as directors except for liability of a director
resulting from (i) a breach of such director's duty of loyalty to the
corporation or its shareholders, (ii) an act or omission that is not in good
faith or that involves intentional misconduct or a knowing violation of laws,
(iii) a transaction from which the director received an improper personal
benefit or (iv) an act or omission for which the liability of the director is
expressly provided by an applicable statute. The Articles limit the liability of
directors of the Company (in their capacity as directors but not in their
capacity as officers) to the Company or its shareholders to the fullest extent
permitted by any applicable law. The inclusion of this provision in the Articles
may reduce the likelihood of derivative litigation against directors and may
discourage or deter shareholders from suing directors for breach of their duty
of care, even though such an action, if successful, might otherwise benefit the
Company and its shareholders. The inclusion of such provisions in the Articles
together with a provision in the Bylaws requiring the Company to indemnify its
directors, officers and certain other individuals against certain liabilities,
is intended to enable the Company to attract qualified persons to serve as
directors who might otherwise be reluctant to do so. The Commission has taken
the position that personal liability of directors for violations of the federal
securities laws cannot be limited and that indemnification by the issuer for
such violations is unenforceable.
 
    The Company has entered into separate indemnification agreements with each
of its directors that may require the Company, among other things, to indemnify
them against certain liabilities that may arise by reason of their status or
service as directors to the maximum extent permitted under the TBCA and advance
their expenses incurred as a result of any proceeding against them for which
they could be indemnified, obtain directors' and officers' insurance or maintain
self-insurance in lieu thereof.
 
                                       67
<PAGE>
    Under the TBCA, the board of directors of a corporation has the power to
amend and repeal the corporation's bylaws unless the corporation's articles of
incorporation reserve the power exclusively to the shareholders or a particular
bylaw expressly provides that the board of directors may not amend or repeal the
bylaw. The Bylaws give the Board of Directors the power to alter, amend or
repeal the Bylaws or adopt new bylaws. The Bylaws also provide that the number
of directors shall be fixed from time to time by resolution of the Board of
Directors. These provisions, in addition to the existence of authorized but
unissued capital stock, may have the effect, either alone or in combination with
each other, of discouraging an acquisition of the Company deemed undesirable by
the Board of Directors.
 
ANTI-TAKEOVER CONSIDERATIONS
 
    ANTI-TAKEOVER STATUTE.  On September 1, 1997, the Company became subject to
newly enacted Part 13 of the TBCA ("Part 13"), which subject to certain
exceptions, prohibits a Texas corporation from engaging in any "business
combination" with an "affiliated shareholder" for three years following the date
that such shareholder became an affiliated shareholder, unless: (i) prior to
such date, the board of directors of the corporation approved either the
business combination or the transaction that resulted in the shareholder
becoming an affiliated shareholder; or (ii) the business combination is
authorized at a meeting of shareholders called not less than six months after
such date by the affirmative vote of at least two-thirds of the outstanding
voting shares not owned by the affiliated shareholder.
 
    Part 13 generally defines a "business combination" to include (i) any
merger, share exchange or conversion involving the corporation and the
affiliated shareholder, (ii) any sale, lease, exchange, mortgage, pledge,
transfer or other disposition of 10% or more of the assets of the corporation to
the affiliated shareholder, (iii) subject to certain exceptions, any transaction
that results in the issuance or transfer by the corporation of any stock of the
corporation to the affiliated shareholder, (iv) any transaction involving the
corporation that has the effect of increasing the proportionate ownership
percentage of the stock of any class or series of the corporation beneficially
owned by the affiliated shareholder, (v) any receipt by the affiliated
shareholder of the benefit of any loans, advances, guarantees, pledges or other
financial benefits provided by or through the corporation or (vi) any adoption
of a plan or proposal for the liquidation or dissolution of the corporation
proposed by, or pursuant to any agreement or understanding with, an affiliated
shareholder. In general, Part 13 defines an "affiliated shareholder" as any
entity or person beneficially owning 20% or more of the outstanding voting stock
of the corporation and any entity or person affiliated with or controlling or
controlled by such entity or person. The provisions of Part 13 could have the
effect of delaying, deferring or preventing a change of control of the Company
even if a change of control were in the shareholders' interests.
 
    CLASSIFIED BOARD OF DIRECTORS.  The Bylaws provide for the Board of
Directors to be divided into three classes serving staggered three-year terms.
The term of office of the first class of directors will expire at the 1999
annual meeting of shareholders, the term of office of the second class will
expire at the 2000 annual meeting of shareholders and the term of office of the
third class will expire at the 2001 annual meeting of shareholders. The terms of
office of the current directors of the Company are set forth herein under
"Management-Executive Officers and Directors."
 
    At each annual meeting of shareholders, the class of directors to be elected
at such meeting will be elected for a three-year term, and the directors in the
other two classes will continue in office. The staggered terms for directors may
affect the shareholders' ability to change control of the Company even if a
change of control were in the shareholders' interests.
 
    SHAREHOLDER ACTION.  As permitted by the TBCA, the Articles provide that any
action which is required to be, or may be, taken at any annual or special
meeting of the shareholders, may be taken without a meeting, without prior
notice, and without a vote, if a consent or consents in writing is signed by the
holder or holders of shares having not less than the minimum number of votes
that would be necessary to take such action at a meeting at which the holders of
all shares entitled to vote on the action
 
                                       68
<PAGE>
were present and voted. This provision could cause shareholders to approve
proposals in a more expeditious manner, which at times could be detrimental to
the minority shareholders.
 
TRANSFER AGENT AND REGISTRAR
 
    The transfer agent and registrar for the Common Stock is First Chicago Trust
Company of New York.
 
                                       69
<PAGE>
                        SHARES ELIGIBLE FOR FUTURE SALE
 
    Prior to this offering, there has been no market for the Common Stock of the
Company. Future sales of substantial amounts of Common Stock in the public
market, or the perception that such sales might occur, could adversely affect
the market price of the Common Stock and could impair the ability of the Company
to raise equity capital in the future.
 
   
    Upon completion of this offering, the Company will have a minimum of
23,619,769 shares and a maximum of 24,776,753 shares of Common Stock
outstanding. All of the shares offered hereby will be freely tradeable without
restriction or further registration under the Securities Act, unless purchased
by an "affiliate" of the Company, as that term is defined in Rule 144, as
described below.
    
 
SALES OF RESTRICTED SHARES
 
   
    The shares of Common Stock which are not being sold in this offering are
"restricted securities" within the meaning of Rule 144. Depending on whether the
minimum or maximum number of shares of Common Stock offered hereby are sold,
there will be, respectively, 22,118,769 or 19,481,738 Restricted Shares
outstanding upon the completion of this offering. Of such Restricted Shares,
20,999,602 shares or 19,362,571 shares, respectively, will be eligible for sale
in the public market after the date of this Prospectus, all under and subject to
the restrictions contained in Rule 144.
    
 
   
    In general, under Rule 144, a person (or persons whose shares are required
under Rule 144 to be aggregated), including an "affiliate" of the Company, as
that term is defined under the Securities Act and the regulations promulgated
thereunder (an "Affiliate"), who has beneficially owned Restricted Shares for at
least one year is entitled to sell, within any three-month period, a number of
such shares that does not exceed the greater of (i) one percent of the then
outstanding shares of Common Stock (approximately 236,197 shares or 247,767
shares, respectively, immediately after this offering) or (ii) the average
weekly trading volume in the Common Stock during the four calendar weeks
preceding the date on which notice of such sale is filed, provided certain
requirements concerning availability of public information, manner of sale and
notice of sale are satisfied. In addition, Affiliates must comply with the
restrictions and requirements of Rule 144, other than the one-year holding
period requirement, in order to sell shares of Common Stock which are not
restricted securities. Under Rule 144(k), a person who is not an Affiliate and
has not been an Affiliate for at least three months prior to the sale and who
has beneficially owned Restricted Shares for at least two years may resell such
shares without compliance with the foregoing requirements. In meeting the one-
and two-year holding periods described above, a holder of Restricted Shares can
include the holding periods of a prior owner who was not an Affiliate. The one-
and two-year holding periods described above do not begin to run until the full
purchase price or other consideration is paid by the person acquiring the
Restricted Shares from the issuer or an Affiliate.
    
 
LOCK-UP ARRANGEMENT
 
   
    Prior to the completion of this offering, the Company intends to enter into
the Lock-up Agreements with each of its shareholders and option holders. Under
the Lock-up Agreements, such shareholders will agree, subject to certain
exceptions, not to offer, sell, contract to sell or otherwise dispose of any
shares of Common Stock until the Lock-up Expiration Date. Upon the expiration of
the Lock-up Agreements, those shares subject to Lock-up Agreements will not,
absent registration, be freely tradeable, but will become eligible for sale
under Rule 144 on various dates in the future.
    
 
OPTIONS
 
    Rule 701 also provides that the shares of Common Stock acquired upon the
exercise of currently outstanding options issued under the Company's stock plans
may be resold by persons, other than Affiliates, beginning 90 days after the
effective date of this Prospectus, subject only to the manner of sale provisions
of Rule 144, and by Affiliates under Rule 144, without compliance with its
one-year minimum
 
                                       70
<PAGE>
   
holding period, subject to certain limitations. As of September 30, 1998,
2,000,000 shares of Common Stock were subject to options issued under the
Company's 1997 Stock Option Plan 1,600,000 of which will become exercisable 90
days after the completion of this offering and 400,000 of which will become
vested and exercisable ratably over a three year period. No shares remained
available for future grants under the 1997 Stock Option Plan. Under the
Company's 1998 Stock Option Plan, as of September 30, 1998, options to purchase
243,000 shares of Common Stock were outstanding, all of which will become vested
and exercisable ratably over a three year period. Options to purchase an
additional 757,000 shares of Common Stock may be granted under the 1998 Stock
Option Plan. In addition, the Non-Plan Option to acquire 100,000 shares of
Common Stock is outstanding, but was not exercisable as of the date of this
Prospectus. As soon as practicable following this offering, the Company intends
to file a registration statement under the Securities Act to register shares of
Common Stock issuable or previously issued upon the exercise of stock options
granted under the Company's stock option plans. Shares issued upon the exercise
of stock options after the effective date of this Prospectus or previously
issued on exercise generally will be available for sale in the open market.
    
 
REGISTRATION RIGHTS
 
   
    The Company has also issued the Warrant to purchase 475,015 shares of Common
Stock, which is currently fully exercisable, a minimum of 17,031 and a maximum
of 475,015 shares of which may be exercised and sold in this offering. The
holder of the Warrant has certain registration rights with respect to such
shares of Common Stock. See "Description of Capital Stock-Warrant Shares."

<PAGE>
                              PLAN OF DISTRIBUTION
 
GENERAL
 
   
    The Company and the Selling Shareholders are offering to sell up to
5,295,015 shares of the Company's Common Stock to its Associates and employees.
The Common Stock will be offered by the Company on a "best efforts" basis. Of
the minimum of 2,500,000 shares, 1,500,000 are being offered by the Company and
1,000,000 are being offered by the Selling Shareholders. The next 1,055,000
shares to be sold are being offered by certain of the Selling Shareholders.
Sales of an amount of shares in excess of 3,555,000 up to 4,955,000 will be
divided equally between the Company and the Selling Shareholders and sales in
excess of 4,955,000 up to the maximum of 5,295,015 will be made by the Selling
Shareholders. If the Company is unable to sell at least 2,500,000 shares of the
Common Stock offered hereby, the Company will cancel this offering and return
all monies collected from subscribers and held in escrow without interest or
deduction. None of the employees, officers or directors of the Company will
receive any compensation in connection with any offers or sales of Common Stock
in this offering. The Company will also retain a Placement Agent to sell the
Common Stock on a "best efforts" basis. There are no underwriters involved in
this offering. The Company will pay the Placement Agent a selling commission of
up to 4.0% of the gross offering proceeds. The Company and the Placement Agent,
if any, will, in all likelihood, agree to indemnify each other against certain
liabilities, including liabilities under the Securities Act of 1933.
    
 
    The Common Stock will be sold at the price of $8.00 per share. The minimum
number of shares a subscriber is required to purchase in order to subscribe to
the offering hereby will be 100 shares. The Company reserves the right to
withdraw, cancel or modify the offering hereby and to reject subscriptions, in
whole or in part, for any reason, including, without limitation, any
subscription, the acceptance of which may, in the opinion of counsel to the
Company, require registration or qualification of the shares of Common Stock
offered hereby under any state securities laws.
 
DETERMINATION OF OFFERING PRICE
 
    Prior to the offering hereby, there has been no public market for the Common
Stock. The offering price has been arbitrarily determined by the Company and may
not be indicative of the market price for the Common Stock after this offering.
In determining the offering price, the Board of Directors considered, among
other things, the Company's earnings, its view of the Company's prospects, the
earnings of comparable publicly traded nutritional supplement companies and the
trading price of the stock of those companies. The Company makes no
representations as to any objectively determinable value of the Common Stock.
 
SUBSCRIPTION PROCEDURES
 
   
    The Company is presently soliciting non-binding offers to purchase shares of
Common Stock, and will not accept binding subscriptions or accept payment for
any shares until after the Registration Statement of which this Prospectus in a
part has been declared effective by the Commission. After such Registration
Statement has been declared effective, the Company will provide to each
prospective investor a copy of the final Prospectus relating to this offering
which includes an agreement to purchase shares of the Common Stock (the
"Subscription Agreement"). Completed Subscription Agreements, together with the
appropriate payment for the Common Stock, must be mailed to the Placement Agent.
See "Summary-How to Purchase Shares." The Company's acceptance of a subscription
shall be evidenced solely by the delivery to the subscriber of a written
confirmation of sale. Receipt by the Company of a Subscription Agreement and/or
deposit with the Escrow Agent of payment for the subscribed shares as described
below shall not constitute acceptance of a subscription. All subscription
payments and executed Subscription Agreements will be delivered to Bank One,
Texas, N.A. (the "Escrow Agent"). The subscription payments will be deposited
into an escrow account established with the Escrow Agent,
    
 
                                       72
<PAGE>
   
subject to a closing (the "Initial Closing") on such escrowed funds once the
Company has accepted subscriptions for at least 2,500,000 shares and, if all
shares of Common Stock offered hereby are not sold as of the date of the Initial
Closing, to subsequent closings on additional subscriptions received from time
to time as determined by the Company. The Company, through its Placement Agents,
will process and consider for acceptance all qualified subscriptions in the
order received.
    
 
   
    Stock certificates will not be issued to subscribers until such time as good
funds related to the purchase of Common Stock by such subscribers are released
from the escrow account to the Company by the Escrow Agent with respect to the
Initial Closing, or from the Placement Agents to the Company, with respect to
subsequent closings. Until such time as stock certificates are issued to the
subscribers, the subscribers will not be considered shareholders of the Company.
    
 
   
    Subscribers will have no right to a return of their subscription payment
held in the escrow account or by the Placement Agents until the Company decides
not to accept such subscription payment and all interest earned on such funds
will belong to the Company.
    
 
TERMINATION OF OFFERING
 
   
    This offering will commence on the date of this Prospectus and will continue
until the earlier of (i) the date upon which the Escrow Agent receives the
proceeds for all 5,295,015 shares of Common Stock offered hereby in the
specified escrow account; (ii)             , 1998 (subject to the right of the
Company to extend the offering for an additional 90 days to             , 1999);
or (iii) the date upon which the Company terminates this offering for any reason
other than the sale of at least 2,500,000 shares of Common Stock. The Company
has the right to terminate the offering and purchase the shares held in escrow
at any time after the Escrow Agent has received the subscription proceeds for
2,500,000 shares. The Company may terminate this offering at any time until all
5,295,015 shares of Common Stock offered hereby have been sold. If the Company
terminates this offering before the subscription proceeds for 2,500,000 shares
have been received by the Escrow Agent, all subscription proceeds will be
promptly returned to subscribers.
    
 
LOCK-UP ARRANGEMENT
 
   
    Prior to the completion of this offering, the Company intends to enter into
the Lock-up Agreements with each of its shareholders and option holders. Under
the Lock-up Agreements, such shareholders will agree, subject to certain
exceptions, not to offer, sell, contract to sell or otherwise dispose of any
shares of Common Stock until the Lock-up Expiration Date. Upon the expiration of
the Lock-up Agreements, those shares subject to Lock-up Agreements will not,
absent registration, be freely tradeable, but will become eligible for sale
under Rule 144 on various dates in the future.
    
 
                                 LEGAL MATTERS
 
    The validity of the issuance of the shares of Common Stock offered hereby
will be passed upon for the Company by Akin, Gump, Strauss, Hauer & Feld,
L.L.P., Dallas, Texas.
 
                                    EXPERTS
 
    The financial statements of the Company as of December 31, 1997, and for the
year ended December 31, 1997 included in this Prospectus have been so included
in reliance on the report of PricewaterhouseCoopers LLP, independent
accountants, given on the authority of said firm as experts in auditing and
accounting.
 
    The financial statements of the Company as of December 31, 1995 and 1996,
and for each of the two years in the period ended December 31, 1996, included in
this Prospectus have been so included in
 
                                       73
<PAGE>
reliance on the report of Belew Averitt LLP ("Belew Averitt"), independent
accountants, given on the authority of said firm as experts in accounting and
auditing.
 
    In November 1997, the Company advised Belew Averitt that it would no longer
retain the firm as independent accountants. The reports of Belew Averitt on the
Company did not contain an adverse opinion or disclaimer of opinion, nor were
they qualified or modified as to uncertainty, audit scope or accounting
principles. The decision to change accountants was precipitated by the Company's
plan to complete an initial public offering in 1998 and was approved by the
Board of Directors in November 1997. During the periods audited by Belew Averitt
and through November 1997 there were no disagreements with Belew Averitt on any
matter of accounting principles or practices, financial statement disclosure or
auditing scope or procedure, which disagreement(s) if not resolved to the
satisfaction of Belew Averitt, would have caused it to make reference to the
subject matter of the disagreements in connection with its reports.
PricewaterhouseCoopers was engaged by the Company as its independent accountants
in November 1997.
 
                             ADDITIONAL INFORMATION
 
    The Company has filed with the Commission a Registration Statement (which
term shall include any amendments thereto) on Form S-1 under the Securities Act

To Board of Directors and Shareholders of
Mannatech, Incorporated
 
    In our opinion, the accompanying balance sheet and the related statements of
income, of changes in shareholders' equity (deficit) and of cash flows present
fairly, in all material respects, the financial position of Mannatech,
Incorporated at December 31, 1997, and the results of its operations and its
cash flows for the year in conformity with generally accepted accounting
principles. 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 audit. We conducted our audit of these statements in
accordance with generally accepted auditing standards 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. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audit provides a
reasonable basis for the opinion expressed above.

                         NOTES TO FINANCIAL STATEMENTS
 
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. The Company
sells its products in the United States and Canada and is currently planning to
expand into Australia, while continuing to assess the potential of other foreign
markets. Independent associates ("Associates") purchase products, at wholesale,
for the primary purpose of selling to retail consumers or for personal
consumption. In addition, Associates earn commissions on their sales volume.
 
REORGANIZATION
 
    In December 1994, to achieve certain tax efficiencies and to protect certain
of the Company's proprietary rights, the Company transferred certain of its
rights and interests in intellectual property, the right to use a supplier's
trademark and its marketing rights to two affiliated partnerships ("Royalty
Partnership" and "Marketing Partnership," respectively, or collectively "the
Partnerships"). The Marketing Partnership was owned by two affiliated
partnerships that also shared common ownership with the Company. The respective
ownership interests in the Partnerships were structured with the intention of
retaining the same economic interests among the partners as that of the
shareholders of the Company. In the case of the intellectual property and
trademark transferred to the Royalty Partnership, the Company entered into a
17-year agreement with the Royalty Partnership to pay a royalty based on sales
volume. In the case of the Marketing Partnership, the Company paid a commission
based on a specified percentage of sales volume. At the time of transfer, the
rights and interest in intellectual property, supplier's trademark and marketing
rights had a minimal basis. During 1994, the Company also entered into separate
incentive compensation agreements with two of its shareholders pursuant to which
the Company agreed to pay commissions based on specified monthly sales volumes
and increases in number of new enrolled Associates. These agreements were
designed to compensate for the differences in ownership in the Partnerships for
one of the principal shareholders and to provide compensation to a shareholder
in lieu of receiving a Partnership interest.
 
    On June 1, 1997, in order to simplify the Company's ownership structure and
consolidate all operating activities, the Company entered into agreements to
effect a reorganization through merging with the corporate general partners of
the Partnerships (with the Company as the surviving corporation) and exchanging
10,000,000 shares of Common Stock for the entire ownership interests of the
corporate general partners and the Partnerships and issued 2,027,571 shares of
Common Stock in consideration for the cancellation of incentive compensation
agreements with the two shareholder-employees and four other employees of the
Company. The net effect of the foregoing transactions was to increase the
Company's common shares outstanding by 12,027,571 while retaining substantially
the same relative original ownership of the Company. The only ownership
percentage change among the original shareholders related to 208,024 shares
granted to one shareholder in recognition of significant contributions to the
Company, which resulted in minor dilution to the other original seven
shareholders at the time of the exchange. The fair value of these additional
shares was expensed, and is included in cancellation of incentive compensation
agreements in the income statement. No monetary consideration changed hands and
the changes were designed to reestablish the original economic characteristics
of the Company. Aside from the new shares issued to the four employees to cancel
their incentive compensation agreements, relative ownership interests, as
evidenced by retention of economic risks and benefits, remained virtually the
same. After the exchange, the Company terminated and liquidated the Partnerships
at no gain or loss.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    The accompanying financial statements include the accounts of the
Partnerships and the Company as if the merger was consummated on December 31,
1994. The merger was accounted using the historical basis for each entity,
effectively combining the entities as a pooling of interests.
 
USE OF ESTIMATES
 
    In preparing 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.
 
RESTRICTED CASH
 
    At December 31, 1997, $199,619 of cash was held by the Company's former
credit card processor under the terms of the credit card processing agreement.
The Company expects the restricted funds to be released early in 1998.
 
INVENTORIES
 
    Inventories consist of raw materials, work-in-progress and finished goods
and are stated at the lower of cost (using the first-in, first-out method) or
market.
 
PROPERTY AND EQUIPMENT
 
    Property and equipment are stated at cost, less accumulated depreciation
which is computed using the straight-line method over the estimated useful life
of each asset. Expenditures for maintenance and repairs are charged to expense
as incurred. The cost of property and equipment sold or otherwise retired and
the related accumulated depreciation are removed from the accounts and any
resulting gain or loss is included in other (income) expense.
 
    Property and equipment are reviewed for impairment whenever an event or
change in circumstances indicates the carrying amount of an asset or group of
assets may not be recoverable. The impairment review includes a comparison of
future cash flows expected to be generated by the asset or group of assets with
their associated carrying value. If the carrying value of the asset or group of
assets exceeds expected cash flows (undiscounted and without interest charges),
an impairment loss is recognized to the extent the carrying amount of the asset
exceeds its fair value.
 
OTHER ASSETS
 
    Other assets consist of deposits, deferred offering costs and organization
costs. Organization costs are being amortized on a straight-line basis over five
years. Deferred offering costs will be deducted from the proceeds of the
anticipated public offering of the Company's Common Stock.

1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
ACCOUNTS PAYABLE
 
    The Company records book overdrafts in its cash accounts as accounts
payable. Included in accounts payable are book overdrafts of $334,374 and
$1,028,676 at December 31, 1996 and 1997, respectively.
 
INCOME TAXES
 
    The Company accounts for income taxes using the asset and liability approach
to financial accounting and reporting for income taxes. In the event that
differences between the financial reporting bases and the tax bases of the
Company's assets and liabilities result in net deferred tax assets, the Company
evaluates the probability of realizing the future benefits indicated by such
assets. A valuation allowance is provided for a portion or all of the net
deferred tax assets when it is more likely than not that such portion, or all of
such deferred tax assets, will not be realized.
 
    Prior to the merger of the Partnerships, the Company and the Partnerships
filed separate tax returns. Prior to June 1, 1997, no provision for income taxes
was necessary in the financial statements for the income attributable to the
Partnerships because, as partnerships, they were not subject to federal income
tax because the tax effect of their activities flowed through directly to the
individual partners. Beginning June 1, 1997, all income earned by the Company
became subject to income tax.
 
PRO FORMA INFORMATION (UNAUDITED)
 
    Pro forma income tax information has been provided, using the statutory tax
rate of the Company, as if all of the Company's and the Partnerships' income had
been subject to income taxes.
 
REVENUE RECOGNITION
 
   
    Revenue is recognized for product sales upon shipment of the products to the
Associates. Revenues are received for promotional packs provided to Associates,
which include nutritional products and sales aids.
    
 
   
    The Company defers revenue received from the sale of the starter and renewal
packs which is in excess of the 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 fair value of these items. Allocated event revenue from the sales
of these packs was approximately $38,100, $405,000 and $906,000 in 1995, 1996
and 1997, respectively. The allocated event revenues are amortized over a
twelve-month period. Total net deferred revenue was $521,171 and $808,749 at
December 31, 1996 and 1997 respectively.
    
 
    Substantially all product sales are made to Associates at a published
wholesale price. Net sales also reflect product returns and the related refund.
 
ACCOUNTING FOR STOCK-BASED COMPENSATION
 
    The Company has adopted Statement of Financial Accounting Standards No. 123
("FAS 123"), "Accounting for Stock-Based Compensation," for stock-based
compensation issued to nonemployees. FAS 123 requires that stock-based
compensation be measured by the fair value at the date of grant. The

1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
Company measures the cost of stock-based compensation issued to employees under
Accounting Principles Board Opinion 25, "Accounting for Stock Issued to
Employees" ("APB 25"), and its related interpretations. The Company has,
however, provided pro forma disclosures in note 10 for stock-based compensation
accounted for under APB 25, as required by FAS 123.
 
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 $450,000, $1,475,000 and $2,241,000
for 1995, 1996 and 1997, respectively. Literature and promotional items are sold
to Associates to support their sales effort. Such items are included in
inventories and charged to cost of sales when sold.
 
RESEARCH AND DEVELOPMENT COSTS
 
    The Company expenses research and development costs when incurred. Research
and development costs are included in other operating expenses and were
approximately $3,000, $283,000 and $381,000 in 1995, 1996 and 1997,
respectively.
 
SOFTWARE DEVELOPMENT COSTS
 
    The Company capitalizes qualifying costs relating to the development of
internal use software. Capitalization of qualifying costs begins after the
conceptual formulation stage has been completed, and such costs are amortized
over the estimated useful life of the software, which is estimated at five
years. Capitalized costs totaled $58,000 and $1,713,000 in 1996 and 1997,
respectively. The Company did not capitalize any such costs during 1995. The
amounts capitalized in 1997 are included in construction in progress and are
expected to be completed during 1998.
 
    During January 1998, the American Institute of Certified Public Accountants
issued Statement of Position 98-1 "Accounting for the Costs of Computer Software
Developed or Obtained for Internal Use" ("SOP 98-1"). SOP 98-1 becomes effective
for all fiscal years beginning after December 15, 1998. The Company does not
expect the adoption of SOP 98-1 to have a material impact on Company's financial
statements.
 
EARNINGS PER SHARE
 
    The Company calculates earnings per share pursuant to Statement of Financial
Accounting Standards No. 128, "Earnings per Share" ("FAS 128"). FAS 128 requires
dual presentation of basic and diluted earnings per share ("EPS") on the face of
the statement of income for all entities with complex capital structures and
requires a reconciliation of the numerator and denominator of the basic EPS
computation to the numerator and denominator of the diluted EPS computation.
Basic EPS calculations are based on the weighted-average number of common shares
outstanding during the period, while diluted EPS calculations are based on the
weighted-average 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 and
receivables from related parties. The Company utilizes financial

institutions which the Company considers to be of high credit quality. The
Company believes its receivables from related parties at December 31, 1997 and
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, note payable, capital leases and accrued
expenses, approximate their recorded values due to their relatively short
maturities.
 
COMMISSIONS
 
    Commissions to Associates are based on several factors, including direct and
indirect sales, downline growth and training of associates. Commissions are
accrued when earned and generally paid at various times within the following
month.
 
SEGMENT INFORMATION
 
    The Company conducts its business within one industry segment. No Associate
accounted for more than 10% of total sales for the years ended December 31,
1995, 1996 and 1997. Sales to Canadian Associates began in 1996 and were less
than 10% of total sales in 1996. Such sales were 14% of total sales in 1997.
 
RECLASSIFICATIONS
 
    Certain prior years' amounts have been reclassified to conform with the
current year presentation.
 
UNAUDITED INTERIM FINANCIAL INFORMATION
 
   
    In the opinion of management, all adjustments, consisting only of normal
recurring adjustments that are necessary for fair presentation, have been
included in the unaudited financial information for the interim periods ended
September 30, 1997 and 1998.

    Under the Stock Option Plan, incentive stock options granted to employees
are valued using the intrinsic method, are nontransferable and are granted for
terms no longer than ten years and at a price which may not be less than 100% of
the fair value of the common stock on the date of grant. During 1997, the
Company issued 1,244,000 stock options to employees at a price ranging from
$1.35 to $2.00 per share. No compensation cost was recognized as the exercise
price of the options was equal to the fair value of options at the date of
grant. Had compensation cost for employee stock options been determined based on
the Black-Scholes option-pricing model at the grant date, pro forma net income
and earnings per share for 1997 using the following weighted-average assumptions
would have been as follows:

    Under the Stock Option Plan, nonqualified stock options granted to
nonemployees are valued using the fair value method, are nontransferable and are
granted for terms no longer than six years and at a price which may not be less
than 100% of the fair value of the common stock on the date of grant. During
1997, the Company issued 356,000 nonqualified stock options to nonemployees at
an exercise price of $1.35 per share. Additionally, the Company issued 100,000
nonqualified stock options in July 1997. These options are priced at $2.00, vest
immediately, are exercisable after one year and have a term of six years.
 
    During 1997, compensation expense of $155,503 was included in other
operating expenses for the nonemployee options. This expense was determined by
calculating the fair value of options granted on the date of grant using the
Black-Scholes option-pricing model and the following weighted-average
assumptions:

    During 1997, the Company granted to a consulting firm 475,015 warrants to
purchase the same number of shares of the Company's common stock which are
nontransferable and vest as follows: 178,125 shares at issuance and 26,990 each
month through March 1, 1998. The warrants are exercisable at $1.35 per share and
expire on the earlier of May 1, 2003 or 36 months after the warrant shares are
registered for public resale under the Securities Act of 1933. At December 31,
1997, 394,015 of the warrants were vested.
 
    As a provision of the warrant agreement, the consulting firm can require the
Company to repurchase the outstanding warrants between May 1998 and May 1999 for
$300,000. Accordingly, it was determined that the fair value of the warrants as
of December 31, 1997 was $300,000.
 
11.  COMMITMENTS AND CONTINGENCIES
 
    The Company leases certain office space and equipment under various
noncancelable operating leases, and has options to renew and renegotiate most of

agreements with some of its key employees which provide for minimum annual
salaries based on sales volume. However, in 1997 the Company terminated several
of these contracts. As a result of the terminations, the Company incurred
approximately $499,000 in severance of which $145,000 was accrued at December
31, 1997. In December 1997, the Company entered into a purchase commitment with

12.  STOCK SPLIT
 
    On May 14, 1997, the Board of Directors declared a 1,000-for-1 stock split
of the Company's common stock. The Board also approved a change in the stated
par value of common shares from $.01 per share to $.0001 per share, and
increased the number of authorized shares to 100,000,000. All share and per
share data have been retroactively adjusted for this split.
 
    Subsequent to year end, on April 8, 1998, the Company amended its Articles
of Incorporation to reduce the number of authorized shares of common stock to
99,000,000 from 100,000,000. Additionally, the Company has authorized 1,000,000
shares of preferred stock with a par value of $0.01 per share.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    The Company, a Texas corporation, is empowered by Article 2.02-1 of the
Texas Business Corporation Act (the "TBCA"), subject to the procedures and
limitations stated therein, to indemnify certain persons, including any person
who was, is or is threatened to be made a named defendant or respondent in a
threatened, pending, or completed action, suit or proceeding because the person
is or was a director or officer, against judgments, penalties (including excise
and similar taxes), fines, settlements and reasonable expenses (including court
costs and attorneys' fees) actually incurred by the person in connection with
the threatened, pending, or completed action, suit or proceeding. The Company is
required by Article 2.02-1 to indemnify a director or officer against reasonable
expenses (including court costs and attorneys' fees) incurred by him in
connection with a threatened, pending, or completed action, suit or proceeding
in which he is a named defendant or respondent because he is or was a director
or officer if he has been wholly successful, on the merits or otherwise, in the
defense of the action, suit or proceeding. Article 2.02-1 provides that
indemnification pursuant to its provisions is not exclusive of other rights of
indemnification to which a person may be entitled under the corporation's
articles of incorporation or any bylaw, agreement, vote of shareholders or
disinterested directors, or otherwise. The Amended and Restated Bylaws of the
Company provide for indemnification by the Company of its directors and officers
to the fullest extent permitted by the TBCA. In addition, the Company has,
pursuant to Article 1302-7.06 of the Texas Miscellaneous Corporation Laws Act,
provided in its Articles that a director of the Company shall not be liable to
the Company or its shareholders for monetary damages for an act or omission in a
director's capacity as director of the Company.
 
    Furthermore, the Company has entered into individual indemnification
agreements with each director of the Company that contractually obligate the
Company to provide to the directors indemnification for liabilities they may
incur in the performance of their duties and insurance or self-insurance in lieu
thereof. The form of such indemnification agreements with a schedule of director
signatories is filed as Exhibit 10.8 hereto.
 
                                      II-1

ITEM 17.  UNDERTAKINGS
 
    Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers, and controlling persons of the
registrant pursuant to Item 14 herein, or otherwise, the registrant has been
advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
 
   
    The undersigned registrant hereby undertakes:
    
 
   
        (1) That, for purposes of determining any liability under the Securities
    Act, the information omitted from the form of prospectus filed as part of
    this registration statement in reliance upon Rule 430A and contained in a
    form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4)
    or 497(h) under the Securities Act shall be deemed to be part of the
    registration statement as of the time it was declared effective.
    
 
   
        (2) That, for the purpose of determining any liability under the
    Securities Act, each post-effective amendment that contains a form of
    prospectus shall be deemed to be a new registration statement relating to
    the securities offered therein, and the offering of such securities at that
    time shall be deemed to be the initial bona fide offering thereof.
    
 
   
        (3) To file, during any period in which offers or sales are being made,
    a post-effective amendment to this registration statement:
    
 
   
            (i) To include any prospectus required by Section 10(a)(3) of the
       Securities Act of 1933;
    
 
   
            (ii) To reflect in the prospectus any facts or events arising after
       the effective date of the registration statement (or the most recent
       post-effective amendment thereof) which, individually or in the
       aggregate, represent a fundamental change in the information set forth in
       the information statement. Notwithstanding the foregoing, any increase or
       decrease in volume of securities offered (if the total dollar value of
       securities offered would not exceed that which was registered) and any
       deviation from the low or high end of the estimated maximum offering
       range may be reflected in the form of prospectus filed with the
       Commission pursuant to Rule 424(b) if, in the aggregate, the changes in
       volume and price represent no more than 20 percent change in the maximum
       aggregate offering price set forth in the "Calculation of Registration
       Fee" table in the effective registration statement.
    
 
   
           (iii) To include any material information with respect to the plan of
       distribution not previously disclosed in the registration statement or
       any material change to such information in the registration statement;
    
 
   
        (4) That, for the purpose of determining any liability under the
    Securities Act of 1933, each such post-effective amendment shall be deemed
    to be a new registration statement relating to the securities offered
    therein, and the offering of such securities at that time shall be deemed to
    be the initial BONA FIDE offering thereof.
    
 
   
        (5) To remove from registration by means of a post-effective amendment
    any of the securities being registered which remain unsold at the
    termination of the offering.

registration statement on Form S-1 (the "Registration Statement") filed with 
the Securities and Exchange Commission on September 10, 1998.

    We have, as counsel, examined such corporate records, certificates and 
other documents and reviewed such questions of law as we have deemed 
necessary, relevant or appropriate to enable us to render the opinions listed

signatures and the authenticity of all documents examined by us.  As to 
various questions of fact material to such opinions, we have relied upon 
representations of the Company.

    Based upon such examination and representations, we advise you that, in 
our opinion:

    A.   The shares of Common Stock which are to be sold and delivered by the 
Company and certain selling shareholders of the Company (the "Selling

validly authorized by the Company.

agrees that Executive's employment shall be subject to the policies 
maintained and established by Company, as the same may be amended from time 
to time.

     1.4  OTHER INTERESTS.  Executive agrees, during the period of 
Executive's employment by Company, to devote Executive's primary business 
time, energy, and best efforts to the business and affairs of Company and its 
Affiliates and not to engage, directly or indirectly, in any other business

parties recognize and agree that Executive may, without consent of the Board 
of Directors, engage in charitable, civic, and other business activities that

     1.5  DUTY OF LOYALTY.  Executive acknowledges and agrees that Executive 
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, 
Executive shall make full disclosure to Company of all business opportunities 
pertaining to Company's business and shall not appropriate for Executive's 
own benefit business opportunities concerning the subject matter of the 
fiduciary relationship.  

                                     II.
                          COMPENSATION AND BENEFITS

     2.1   BASE SALARY.  During the period of this Agreement, Executive shall 
receive a minimum annual base salary of  $__________.  Executive's annual 
base salary shall be reviewed by the Board of Directors (or a committee 
thereof) on not less than an annual basis, and, in the sole discretion of the 
Board of Directors (or such committee), such annual base salary may be 
increased, but not decreased unless mutually agreed to in writing by both 
Company and Executive, effective as of January 1 of each year.  Executive's 
annual base salary shall be paid in equal installments in accordance with the 
Company's standard policy regarding payment of compensation to executives but 
no less frequently than monthly.

     2.2  BONUS.  During the period of Executive's employment under this 
Agreement, Executive shall be eligible, from time to time, but not less than 
annually, to receive a bonus, with the amount of such bonus to be determined 
under any incentive or bonus plan established by Company and, in the absence 
of any such plan, by the Board of Directors (or a committee thereof) based 
upon criteria established from time to time by the Board of Directors (or 
such committee).

     2.3  EMPLOYEE BENEFITS.  During the period of Executive's employment 
under this Agreement, Executive shall be allowed to participate in any 
benefit plans and programs, including improvements or modifications of the 
same, which are now, or may hereafter be, available to other executive 
employees of Company in general.  Such benefit plans and programs shall 
include, without limitation, any deferred compensation plan, profit sharing 
plan, thrift plan, health insurance or group health plan, life insurance, 
disability insurance, pension plan, supplemental retirement plan, stock 
option plan, sick leave plan, and the like, which may be maintained by 
Company for Executive specifically or for employees of Executive's seniority 
and position generally.  Company shall not, however, by reason of this 
Section 2.3 either (i) be obligated to institute, maintain, or refrain from 
changing, amending, or discontinuing any such benefit plan or program or (ii) 
be obligated to provide Executive with all benefits provided to any other 
person or individual employed by Company.  

     2.4  VACATION.  During the period of Executive's employment under this 
Agreement, Executive shall be entitled to a number of vacation days each year 
in accordance with the following schedule:

     As provided by the Company policy, but in any event not less than as 
provided by the following schedule:

                                       2
<PAGE>

<TABLE>
<CAPTION>
               YEAR                     VACATION DAYS
               --------------------------------------
<S>                                     <C>
               1998                     15 days

               2000 and thereafter      20 days
</TABLE>

To the extent Executive fails to take his full number of vacation days in any 
given year, Executive shall have no right to carry over accrued but unused 
vacation to any subsequent year, but Company shall pay additional 
compensation to Executive in an amount equal to Executive's annual base 
salary as in effect pursuant to Section 2.1 for such year, prorated for the 
number of unused vacation days in such year.  Vacation days provided under 
this Agreement shall be offset by vacation days available to Executive under 
any other Company vacation plan or policy.

Executive's employment under this Agreement, subject to Company's standard 
policies and procedures with respect to expense reimbursement as applied to

Executive for business-related purposes, including, but not limited to, 
reasonable dues and fees to industry and professional organizations and 
reasonable costs of entertainment and business development.

     2.6  INDEMNIFICATION.  During the period of Executive's employment under 
this Agreement, Company agrees to indemnify Executive against any and all 
liabilities arising out of Executive's employment duties under this Agreement 
to the extent such liabilities are not covered by any insurance maintained by 
Company or Executive, but excluding liabilities that are caused by or result, 
in whole or in part, from Executive's own negligence or willful misconduct.
     
     2.7  DIRECTORS' AND OFFICERS' LIABILITY INSURANCE.  Company shall 
purchase and, during the period of Executive's employment under this 
Agreement, maintain a reasonable level of directors' and officers' liability 
insurance covering Executive's employment position identified in Section 1.2, 
but only if and to the extent such coverage is available at a reasonable 
premium cost as determined by and in the sole discretion of the Board of 
Directors.

                                     III.

hereof, Company agrees to employ Executive under the terms of this Agreement 
for an initial term of five years, which shall begin on the Effective Date 
and end on the fifth anniversary of the Effective Date.  Said term shall be 
extended automatically for an additional successive one-year period as of 
each anniversary of the Effective Date after the initial term.; provided, 
however, that if either party shall give written notice to the other at least 
thirty days prior to such anniversary, then no such automatic extension shall 
occur and Executive's employment under this Agreement shall terminate on the 
day prior to such anniversary.  

     3.2  COMPANY'S RIGHT TO TERMINATE.  Notwithstanding the provisions of 
Section 3.1, Company shall have the right to terminate Executive's employment

          (i)   Upon Executive's death;

          (ii)  Upon Executive's becoming incapacitated by accident, sickness,
     or other circumstance that renders Executive mentally or physically
     incapable of performing the essential duties and services required of
     Executive hereunder, with or without reasonable accommodation, for a period
     of at least 120 consecutive calendar days;

          (iii) For Cause;

          (iv)  For Executive's material breach of any material provision of
     this Agreement which, if correctable, remains uncorrected for thirty days
     following written notice to Executive by Company of such breach; or

          (v)   For any other reason whatsoever, in the sole discretion of the
     Board of Directors.

     3.3  EXECUTIVE'S RIGHT TO TERMINATE.  Notwithstanding the provisions of
Section 3.1, Executive shall have the right to terminate Executive's employment
under this Agreement at any time for any of the following reasons:

          (i)   A material breach by Company of any material provision of this

          (ii)  For Good Reason; or

          (iii) For any other reason whatsoever, in the sole discretion of

terminate Executive's employment hereunder at any time prior to expiration of 
the term provided in Section 3.1, Company or Executive shall do so by giving 
written notice of such termination to the other party and stating the 
effective date and reason for such termination; provided, however, that no 
such action shall alter or amend any other provisions hereof or rights 
arising hereunder, including, without limitation, the provisions of Articles 
V and VI hereof.
                                          
                                     IV.
                     EFFECT OF TERMINATION OF EMPLOYMENT

     4.1  TERMINATION BY EXPIRATION OF TERM.  If Executive's employment 
hereunder shall terminate upon expiration of the term provided in Section 
3.1, all compensation and all benefits to Executive hereunder shall terminate 
contemporaneously with termination of Executive's employment, except for such 
benefits as may be required by law.  

     4.2  TERMINATION BY COMPANY.  If Executive's employment hereunder shall 
be terminated by Company prior to expiration of the term provided in Section 
3.1, regardless of the reason therefor, all compensation and benefits to 
Executive hereunder shall terminate contemporaneously with the termination of 
such employment; provided, however, that if such 

                                       4
<PAGE>

termination shall be for any reason other than those encompassed by Section 
3.2(i), 3.2(ii), 3.2(iii), or 3.2(iv), subject to execution of the release 
described in Section 4.4, Company shall (i) pay Executive Severance Payments 
and (ii) provide Executive with Severance Benefits. The first Severance 
Payment pursuant to this Section shall be paid to Executive within thirty 
days of the date of termination of his employment, and the second, third, 
fourth, and fifth of such payments shall be paid, one each, on the first, 
second, third, and fourth, respectively, anniversary of such termination 
date.      

     4.3  TERMINATION BY EXECUTIVE.  If Executive's employment hereunder 
shall be terminated by Executive prior to expiration of the term provided in 
Section 3.1, regardless of the reason therefor, all compensation and benefits 
to Executive hereunder shall terminate contemporaneously with the termination 
of such employment; provided, however, that if such termination shall be 
pursuant to Section 3.3(i) or 3.3(ii), subject to execution of the release 
described in Section 4.4, Company shall (i) pay Executive Severance Payments 
and (ii) provide Executive with Severance Benefits.  The first Severance 
Payment pursuant to this Section shall be paid to Executive within thirty 
days of the date of termination of his employment, and the second, third, 
fourth, and fifth of such payments shall be paid, one each, on the first, 
second, third, and fourth, respectively, anniversary of such termination 
date.      

     4.4  RELEASE AND FULL SETTLEMENT.  As a condition to the receipt of any 
Severance Payment and/or Severance Benefit hereunder, Executive shall be 
required to execute a release, in the form established by Company, releasing 
Company and Company's shareholders, partners, officers, directors, employees, 
and agents from any and all claims and from any and all causes of action of 
any kind or character, including, but not limited to, all claims or causes of 
action arising out of Executive's employment with Company, the termination of 
such employment, or any actions or omissions occurring during such 
employment, and the performance of Executive's and Company's obligations 
hereunder, and the receipt of any benefits provided hereunder by Executive 
shall constitute full settlement of all such claims and causes of action.

     4.5  CHANGE IN CONTROL.  If, within two years following the occurrence 
of a Change in Control, Executive's employment with Company shall terminate 
under circumstances that would entitle Executive to Severance Payments 
pursuant to Section 4.2 or 4.3, then, in lieu of any Severance Payments or 
Severance Benefits pursuant to Section 4.2 or 4.3, Company shall (i) pay 
Executive Change in Control Payments and (ii) provide Executive with Change 
in Control Benefits. The first Change in Control Payment pursuant to this 
Section shall be paid to Executive within thirty days of the date of 
termination of his employment, and the second, third, fourth, and fifth of 
such payments shall be paid, one each, on the first, second, third, and 
fourth, respectively, anniversary of such termination date.      

     4.6  PARACHUTE PAYMENT GROSS UP.  Notwithstanding anything to the 
contrary in this Agreement, in the event that any Payment would be subject to 
Excise Tax, Company shall pay to Executive a Gross-up Payment.  Company shall 
make an initial determination as to whether a Gross-up Payment is required 
and the amount of any such Gross-up Payment.  Executive shall notify Company 
in writing of any claim by the Internal Revenue Service which, if successful, 
would require Company to make a Gross-up Payment (or a Gross-up Payment in 
excess of that, if any, initially determined by Company) within ten days of 
the receipt of such claim.  Company shall notify Executive in writing at 
least ten days prior to the due date of any response required with respect to 
such claim if it plans to contest the claim.  If Company decides to contest 
such 

                                       5
<PAGE>

claim, Executive shall cooperate fully with Company in such action; provided, 
however, that Company shall bear and pay directly or indirectly all costs and 
expenses (including additional interest and penalties) incurred in connection 
with such action and shall indemnify and hold Executive harmless, on an 
after-tax basis, for any Excise Tax or income tax, including interest and 
penalties with respect thereto, imposed as a result of Company's action.  If, 
as a result of Company's action with respect to a claim, Executive receives a 
refund of any amount paid by Company with respect to such claim, Executive 
shall promptly pay such refund to Company.  If Company fails to timely notify 
Executive whether it will contest such claim, or if Company determines not to 
contest such claim, Company shall immediately pay to Executive the portion of 
such claim, if any, which it has not previously paid to Executive.
 
     4.7   NO DUTY TO MITIGATE LOSSES.  Executive shall have no duty to find 
new employment following the termination of Executive's employment in order 
to trigger Company's obligation to pay any amount to Executive pursuant to 
this Article IV.  Any salary or remuneration received by Executive from a 
third party for the providing of personal services (whether by employment or 
by functioning as an independent contractor) following the termination of 
Executive's employment under circumstances pursuant to which this Article IV 
applies shall not reduce Company's obligation to make a payment to Executive 
(or the amount of any such payment) pursuant to the terms of this Article IV.

     4.8  LIQUIDATED DAMAGES.  In light of the difficulties in estimating the 
damages for an early termination of this Agreement, Company and Executive 
hereby agree that the payments, if any, to be received by Executive pursuant 
to this Article IV shall be received by Executive as liquidated damages and 
not as a penalty.

     4.9  OTHER COMPENSATION PROGRAMS.  This Agreement governs the rights and 
obligations of Executive and Company with respect to Executive's annual base 
salary and certain perquisites of employment.  Except as otherwise 
specifically provided in this Agreement, Executive's rights and obligations 
both during the term of Executive's employment and thereafter with respect to 
any stock options, restricted stock, incentive and deferred compensation, 
life insurance policies insuring the life of Executive, and other benefits 
under plans and programs maintained by Company, if any, shall be governed by 
the separate agreements, plans, programs, and other documents and instruments 
governing such matters, or as may be provided by law. 

     4.10 DEATH OF EXECUTIVE. If Executive is entitled to any Severance 
Payment or Change in Control Payment pursuant to this Article IV and 
Executive dies prior to the completion of all such payments, such payments 
shall cease, and Company shall have no obligation to provide any further 
Severance Payment or Change in Control Payment, as applicable, to Executive's 
estate or to any other person.  

                                      V.
                          PROTECTION OF INFORMATION

     5.1  DISCLOSURE TO EXECUTIVE.  Company shall (i) disclose to Executive, 
or place Executive in a position to have access to or develop, trade secrets 
or confidential information of Company or its Affiliates, and/or (ii) entrust 
Executive with business opportunities of Company 

                                       6
<PAGE>

or its Affiliates, and/or (iii) place Executive in a position to develop 
business good will on behalf of Company or its Affiliates.  

     5.2  DISCLOSURE TO AND PROPERTY OF COMPANY.  All information, ideas, 
concepts, improvements, discoveries, and inventions, whether patentable or 
not, which are conceived, made, developed, or acquired by Executive, 
individually or in conjunction with others, during Executive's employment by 
Company (whether during business hours or otherwise and whether on Company's 
premises or otherwise) that relate to Company's business, products, or 
services (including, without limitation, all such information relating to 
corporate opportunities, research, financial and sales data, pricing terms, 
evaluations, opinions, interpretations, acquisitions prospects, the identity 
of customers or their requirements, the identity of key contacts within the 
customer's organizations or within the organization of acquisition prospects,

property of Company. Moreover, all documents, drawings, memoranda, notes, 
records, files, correspondence, manuals, models, specifications, computer 
programs, electronic mail, voice mail, electronic databases, maps, and all 
other writings or materials of any type embodying any of such information,

Affiliates of the Company shall be third party beneficiaries of Executive's 
obligations under this Section. As a result of Executive's employment by 
Company, Executive may also from time to time have access to, or knowledge 
of, confidential business information or trade secrets of third parties, such 
as customers, suppliers, partners, joint venturers, and the like, of Company 
and its Affiliates.  Executive also agrees to preserve and protect the 
confidentiality of such third party confidential information and trade 
secrets to the same extent, and on the same basis, as Company's confidential 
business information and trade secrets.  Executive shall refrain, both during 
the employment relationship and after the employment relationship terminates, 
from publishing any oral or written statements about Company, any of its 
Affiliates, or any of such entities' officers, employees, agents, or 
representatives (i) that are slanderous, libelous, or defamatory, or (ii) 
that disclose private or confidential information about Company, any of its 
Affiliates, or any of such entities' business affairs, officers, employees, 
agents, or representatives, or (iii) that constitute an intrusion into the 
seclusion or private lives of Company, any of its Affiliates, or any of such 
entities' officers, employees, agents, or representatives, or (iv) that give 
rise to unreasonable publicity about the private lives of Company, any of its 
Affiliates, or any of such entities' officers, employees, agents, or 
representatives, or (v) that place Company, any of its Affiliates, or any of 
such entities' officers, employees, agents, or representatives in a false 
light before the public, or (vi) that constitute a misappropriation of the 
name or likeness of Company, any of its Affiliates, or any of such entities' 
officers, employees, agents, or representatives.  A violation or threatened 
violation of this prohibition may be enjoined by the courts.

     5.4  OWNERSHIP BY COMPANY.  If, during Executive's employment by 
Company, Executive creates any work of authorship fixed in any tangible 
medium of expression, which is the subject matter of copyright (such as 
videotapes, written presentations, or acquisitions, computer programs, 
electronic mail, voice mail, electronic databases, drawings, maps, 
architectural renditions, models, manuals, brochures, or the like) relating 
to Company's business, products, or services, whether such work is created 
solely by Executive or jointly with others (whether during business hours or 
otherwise and whether on Company's premises or otherwise), Company shall be 
deemed the author of such work if the work is prepared by Executive in the 
scope of Executive's employment, or, if the work is not prepared by Executive 
within the scope of Executive's employment but is specially ordered by 
Company as a contribution to a collective work, as a part of a motion picture 
or other audiovisual work, as a translation, as a supplementary work, as a 
compilation, or as an instructional text, then the work shall be considered 
to be work made for hire and Company shall be the author of the work.  If 
such work is neither prepared by Executive within the scope of Executive's 
employment nor a work specially ordered that is deemed to be a work made for 
hire, then Executive hereby agrees to assign, and by these presents does 
assign, to Company all of Executive's worldwide right, title, and interest in 
and to such work and all rights of copyright therein.

     5.5  ASSISTANCE BY EXECUTIVE.  Both during the period of Executive's 
employment by Company and thereafter, Executive shall assist Company and its 
nominee, at any time, in the protection of Company's worldwide right, title, 
and interest in and to information, ideas, concepts, improvements, 
discoveries, and inventions, and its copyrighted works, including without 
limitation, the execution of all formal assignment documents requested by 
Company or its nominee and the execution of all lawful oaths and applications 
for patents and registration of copyright in the United States and foreign 
countries.

     5.6  REMEDIES.  Executive acknowledges that money damages would not be 
sufficient remedy for any breach of this Article by Executive, and Company 
shall be entitled to enforce the provisions of this Article by terminating 
any and all payments then owing to Executive under this Agreement and/or to 
specific performance and injunctive relief as remedies for such breach or any 
threatened breach.  Such remedies shall not be deemed the exclusive remedies 
for a breach of this Article, but shall be in addition to all remedies 
available at law or in equity to Company, including the recovery of damages 
from Executive and his agents involved in such breach and remedies available 
to Company pursuant to other agreements with Executive.  

                                     VI.
                          NONCOMPETITION OBLIGATION

     6.1  IN GENERAL.  As part of the consideration for the compensation and 
benefits to be paid to Executive hereunder; to protect the trade secrets and 
confidential information of Company and its Affiliates that have been and 
will in the future be disclosed or entrusted to Executive, the business good 
will of Company and its Affiliates that has been and will in the future be 
developed in Executive, and the business opportunities that have been and 
will in the future be disclosed or entrusted to Executive by Company and its 
Affiliates; and, as an additional incentive for Company to enter into this 
Agreement, Company and Executive agree to the noncompetition obligations 
hereunder.  Executive shall not, directly or indirectly for Executive or for 
others, in any geographic area or market where Company or any of its 
Affiliates are 

                                       8
<PAGE>

conducting any business as of the date of the termination of the employment 
relationship or have during the previous twelve months conducted such 
business:

          (i)   Engage in any business competitive with the business conducted
     by Company;

          (ii)  Render advice or services to, or otherwise assist, any other
     person, association, or entity who is engaged, directly or indirectly, in
     any business competitive with the business conducted by Company with
     respect to such competitive business; or

          (iii) Induce any employee of Company or any of its Affiliates to
     terminate his or her employment with Company or such Affiliates, or hire or
     assist in the hiring of any such employee by any person, association, or
     entity not affiliated with Company.

These noncompetition obligations shall apply during the period that Executive 
is employed by Company and for an additional period of one year following 
Executive's termination of employment with Company for any reason; provided, 
however, that if Executive is entitled to receive any payment or benefit from 
Company pursuant to Article IV, such obligations shall extend for the 
duration of the period during which Executive is receiving any payment or 
benefits pursuant to this Agreement after termination of the employment 
relationship if such period is later than any period previously described in 
this sentence.    
  
     6.2  ENFORCEMENT AND REMEDIES.  Executive understands that the 
restrictions set forth in Section 6.1 may limit Executive's ability to engage 
in certain businesses anywhere in the world during the period provided for 
above, but acknowledges that Executive will receive sufficiently high 
remuneration and other benefits under this Agreement to justify such 
restriction.  Executive acknowledges that money damages would not be a 
sufficient remedy for any breach of this Article by Executive, and Company 
shall be entitled to enforce the provisions of this Article by terminating 
any payments then owing to Executive under this Agreement and/or to specific 
performance and injunctive relief as remedies for such breach or any 
threatened breach.  Such remedies shall not be deemed the exclusive remedies 
for a breach of this Article, but shall be in addition to all remedies 
available at law or in equity to Company, including without limitation, the 
recovery of damages from Executive and Executive's agents involved in such 
breach and remedies available to Company pursuant to other agreements with 
Executive.  

     6.3  REFORMATION.  It is expressly understood and agreed that Company 
and Executive consider the restrictions contained in this Article to be 
reasonable and necessary to protect the proprietary information of Company.   
Nevertheless, if any of the aforesaid restrictions are found by a court 
having jurisdiction to be unreasonable, or overly broad as to geographic area 
or time, or otherwise unenforceable, the parties intend for the restrictions 
therein to be modified by such court so as to be reasonable and enforceable 
and, as so modified by the court, to be fully enforced.

Attn: Charles E. Fioretti, Chairman of the Board and Chief Executive Officer

Dear Mr. Fioretti:

     This letter agreement sets forth our understanding with respect to the 
proposed directed public offering ("Directed Public Offering") of common 
stock of Mannatech Incorporated ("the Company") to your Associates and 
employees.

1.  J.J.B. Hilliard, W.L. Lyons, Inc. (referred to hereafter as "Hilliard" or 
    the "Placement Agent") presently intends, subject to the satisfactory 
    completion of ongoing due diligence and the other provisions of this 
    letter, to assist the Company in placing directly with its Associates 
    and/or employees, on a best efforts basis in the form of the Directed 
    Public Offering, a minimum of 1,500,000 shares, and a maximum of 2,200,000 
    shares of the Company's Common Stock to be sold by the Company (the 
    "Primary Shares") and a maximum of 2,755,000 shares of the Common Stock to 
    be sold by certain selling shareholders (the "Selling Shareholders' 
    Shares"). Together, the Primary Shares and Selling Shareholders' Shares 
    are hereafter collectively referred to as "Offered Shares."

    The Offered Shares will have certain material restrictions on liquidity, 
    which restrictions will be fully described in all Securities and Exchange 
    Commission ("SEC") and Blue Sky filings and to all Associates and 
    employees whom the Company solicits to purchase Offered Shares. Among 
    other things, the Offered Shares will be restricted upon subsequent resale 
    following the Directed Public Offering to then-current Associates and/or 
    employees of the Company. Such restriction, for as long as it remains in 
    effect, will appear as a legend on all applicable share certificates.

    structure and financial condition, among other things, it is anticipated 
    that the offering price will be approximately $8.00 per share, a 
    value arrived at by the Company's Board of Directors after consideration 
    of a number of relevant factors.

3.  The Company will promptly take all steps necessary to effectuate the 
    Directed Public Offering including (i) using its reasonable best efforts 
    to cause an S-1 registration statement (the "Registration Statement") to 
    be prepared, filed and declared effective by the Securities and Exchange 
    Commission as soon as practicable; and (ii) undertake, in cooperation with 
    Hilliard and its counsel, the qualification of the Offered Shares for 
    sale in the states designated by the Company, which qualification shall be 
    completed by the Company's outside counsel.

4.  The best efforts management fee to which the Placement Agent shall be 
    entitled shall be four percent (4%) of the aggregate value of the Offered 
    Shares placed with Associates and other employees, payable as set forth 
    below.

    Such best efforts management fee will be contingent upon and payable on 
    the date or dates of closing of the Directed Public Offering, in stages as 
    the Directed Public Offering is completed. It is presently contemplated 
    that the Company will sell first a minimum of 1,500,000 Primary Shares, 
    collecting funds in a designated escrow account. At stages, as yet 
    undetermined, funds will be released from escrow and share certificates 
    distributed. At each stage or stages of escrow release, the Placement 
    Agent will be due its appropriate portion of the contingent management fee.

    Among other things, Hilliard will assist the Company with (i) the 
    preparation of the Registration Statement, (ii) the Company's solicitation 
    of Associates and employees to purchase Offered Shares, (iii) the 
    distribution of materials, as appropriate, to Associates and employees, 
    (iv) receipt and processing of subscriptions to purchase Offered Shares 
    from Associates and employees, (v) follow up, administrative and recording 
    duties related to the Company's solicitation of Associates and employees, 
    (vi) opening accounts, where appropriate, for certain Associates and 
    employees, (vii) administrative matters related to closing or closing for 
    the Directed Public Offering, including without limitation the transmission 
    of subscription and other relevant information concerning subscribers of 
    the Offered Shares to the Company's escrow agent for the Directed Public 
    Offering and the Company's transfer agent, (viii) cooperating with the 
    Company in regard to Blue Sky registration and other regulatory matters 
    respecting the Directed Public Offering, and (ix) such other 
    administrative duties as may be requested by the Company and appropriate 
    to perform in assisting the Company with the Directed Public Offering. The 
    Placement Agent will cooperate fully including, when possible, opening

    accounts for purchasers as the Company shall request, to maximize the 
    availability of state Blue Sky exemptions where applicable or desired by 
    the Company.

    The Company will pay to the Placement Agent a retention fee of $50,000 
    ("Retention Fee"), payable upon the execution of this letter agreement. It 
    is understood that upon completion of all or any portion of the Directed 
    Public Offering, the Retention Fee will be credited against the 
    contingent management fee. Should Hilliard's Commitment Committee fail to 
    authorize Hilliard to serve as Placement Agent for the Directed Public 
    Offering by no later than September 16, 1998, then Hilliard shall return 
    the Retention Fee, less reasonable and necessary expenses, including 
    legal and out-of-pocket expenses, in consideration of the undertaking as 
    contemplated by this letter. No expenses in excess of $50,000 shall, in any 
    event, be reimbursed by the Company to Hilliard. In the event the Directed 
    Public Offering is canceled prior to completion for any reason, after 
    September 16, 1998, the Retention Fee is understood to be non-refundable 
    and to have been earned in full.

    The Company will pay all of its own expenses and fees incurred in 
    connection with the Directed Public Offering and the solicitation of the 
    purchase of shares thereunder including all regulatory and filing fees as 
    may be incurred.

5.  If the Directed Public Offering is cancelled by the Company prior to 
    completion for any reason after acceptance by Hilliard's Commitment 
    Committee, then the Company will promptly reimburse the Placement Agent 
    for reasonable and accountable out-of-pocket expenses, including fees 
    and disbursements of Placement Agent's counsel, incurred in connection 
    with the Directed Public Offering, up to an aggregate amount not to exceed 
    an additional $50,000, over and above the Retention Fee. If the Directed 
    Public Offering is consummated as contemplated herein, the Placement Agent 
    will bear its own expenses incurred in connection with the assistance 
    provided to the Company in connection with the Directed Public Offering.

6.  In addition to its ongoing due diligence in connection with the Directed 
    Public Offering, the Placement Agent and its counsel will satisfy 
    themselves by performing a preliminary due diligence review of the 
    Company's business and financial condition. The Company will direct its 
    counsel, independent accountants, officers and directors to cooperate 
    with the Placement Agent's representatives in any due diligence review 
    performed by Hilliard. Such preliminary due diligence review, as well as 
    the Placement Agent's Commitment Committee approval will be completed by 
    no later than September 16, 1998.

7.  Hilliard's compensation in respect of the Directed Public Offering shall 
    not be reduced even if the Company should engage another investment 
    banking firm concerning the 

<PAGE>

Page 4


    rendering of the services set forth herein by such other investment 
    banking firm in connection with the Directed Public Offering, unless 
    Hilliard shall otherwise agree.

8.  Incident to the Directed Public Offering the Company shall be responsible 
    for: (i) preparation, filing and declaration of effectiveness by the SEC 
    of the Registration Statement as referred to in Sections 2 and 5 herein; 
    (ii) preparation of the current and projected operating results of the 
    Company in accordance with Generally Accepted Accounting Principles, 
    consistently applied; (iii) obtaining the determination of the Company's 
    outside counsel, with the reasonable concurrence of Hilliard's counsel, 
    that (a) no material Blue Sky registration problems or restrictions, (b) 
    compliance with such restrictions of requirement has occurred and/or (c) 
    that the Company has decided not to offer the Directed Public Offering in 
    certain states, as the case may be.

    Hilliard's undertaking to proceed with the Directed Public Offering is 
    contingent upon Hilliard and its counsel having conducted a satisfactory 
    review of the financial, business, legal, regulatory and other affairs of 
    the Company and approval of Hilliard's participation in the Directed 
    Public Offering by its Commitment Committee, all of which shall be 
    concluded on or before September 16, 1998.

9.  The obligations of the Placement Agent and those of the Company to 
    complete the Directed Public Offering will be subject to the execution 
    and delivery of a best efforts agency agreement in a form and containing 
    terms and conditions acceptable to the parties for offerings of this type 
    and containing, among other things, customary representations, 
    warranties, covenants and conditions as well as specified indemnification 
    of the Placement Agent by the Company.

10. Hilliard acknowledges that pursuant to the various reviews which it 
    contemplates undertaking, it will be afforded by the Company information 
    which the Company considers confidential. Any information which is 
    afforded by the Company, in any form, to Hilliard concerning its 
    operations, its affairs, its business, its personnel and its Associates, 
    without limitation, unless the same is included in the Company's 
    registration statement (or any amendment thereto) filed with the 
    Securities and Exchange Commission, shall be deemed confidential 
    information ("Confidential Information"). Hilliard (including its 
    employees and contractors) agrees to hold in confidence any and all 
    Confidential Information, that has been or will be disclosed, directly or 
    indirectly to Hilliard, confidential from any third party, unless the 
    disclosure of such Confidential Information is authorized in writing in 
    advance by the Company, or where such disclosure may be required by law, 
    and then only after notice to, and opportunity for consultation with, the 
    Company by Hilliard. In the event that the contemplated Directed Public 
    Offering is terminated by either party, or upon the written request of the 
    Company,

<PAGE>

Mr. Charles E. Fioretti

    any Confidential Information in tangible form shall be returned to the 
    Company by Hilliard and its various outside professionals.

11. Except as to this letter agreement regarding the payment of fees and 
    expenses set forth in Sections 4 and 5 herein, and the provisions of 
    Sections 8 and 10 this letter of intent is not intended to constitute a 
    binding agreement.

    Should Hilliard not accept the undertaking of Placement Agent on or 
before September 16, 1998, the Company may but shall not be obligated to 
accept Hilliard as Placement Agent for the Directed Public Offering and may 
contract with others for such purpose unless the terms of this letter are 
extended in writing by the Company. If the foregoing is is accord with your 
understanding, please sign and return the enclosed copy of this letter, 
together with a check in the amount of fifty thousand dollars ($50,000).
