NOTE 1    ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Mannatech, Incorporated (the "Company") was incorporated in the State of

     The accompanying unaudited consolidated financial statements have been
prepared in accordance with generally accepted accounting principles for interim
financial information and with the instructions to Form 10-Q and Rule 10-01 of
Regulation S-X. Accordingly, they do not include all of the information and
footnotes required by generally accepted accounting principles for complete
financial statements. In the opinion of Company's management, the accompanying
unaudited consolidated financial statements contain all adjustments, consisting
of normal recurring adjustments, considered necessary for a fair statement of
the Company's financial information as of and for the periods presented. The
consolidated results of operations of any interim period are not necessarily
indicative of the consolidated results of operations to be expected for the
fiscal year. For further information, refer to the consolidated financial
statements and accompanying footnotes included in the Company's annual report on
Form 10-K for the year ended December 31, 2000.

Principles of Consolidation

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

Revenue Recognition

     The Company's revenues consist of sales from products sold, sales from
starter and renewal packs sold and shipping fees charged. Substantially all
product sales are made to Associates at a published wholesale price. Net sales
also include product returns and any related refunds. The Company records a
reserve for product returns based on its historical experience. The Company
adopted Staff Accounting Bulletin No. 101 "Revenue Recognition in Financial
Statements" ("SAB 101") in the fourth quarter of 2000. Under SAB 101, the
Company recognizes revenue for product sales upon the receipt of the products by
the consumers. As a result of adopting SAB 101, the Company has restated all of
the 2000 quarterly financial information, previously reported to reflect the
recording of a one-time charge of $210,000, net of tax of $126,000 for the
cumulative effect of this change at January 1, 2000. Beginning in 2000, the
Company began deferring all of its revenues until the consumer receives the
shipment.

                            MANNATECH, INCORPORATED
     NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) - (Continued)

     The Company also defers revenue received from sales of the starter and
renewal packs, which are in excess of the average wholesale value of the
individual items included in such packs and amortizes such deferrals over a
twelve-month period. Total deferred revenue was $691,000 and $866,000 at
December 31, 2000 and March 31, 2001, respectively.

Shipping and Handling Cost

     In accordance with the Emerging Issue Task Force No. 00-10 "Accounting for
Shipping and Handling Fees and Costs," the Company records freight and shipping
revenues, collected from the Associate, as revenue. The Company records in-bound
freight and shipping costs as a part of cost of sales and the Company records
shipping and handling costs associated with shipping products to its Associate
as selling and administrative expenses. Total shipping and handling costs
included in the selling and administrative expense was approximately $1.6
million and $2.1 million for the three months ended March 31, 2001 and 2000,
respectively.

Earnings Per Share

     The Company calculates earnings (loss) per share pursuant to Statement of
Financial Accounting Standards No. 128, "Earnings Per Share" ("FAS 128"). FAS
128 requires dual presentation of basic and diluted earnings (loss) per share
("EPS") on the face of the consolidated statement of operations for all entities
with complex capital structures and requires a reconciliation of the numerator
and denominator of the basic EPS computation to the numerator and denominator of
the diluted EPS computation. Basic EPS calculations are based on the weighted-
average number of common shares outstanding during the period, while diluted EPS
calculations are calculated using the weighted-average number of common shares
and dilutive common share equivalents outstanding during each period. At March
31, 2000, all of the 2,074,000 common stock options were excluded from the
diluted EPS calculation and at March 31, 2001, all of the 3,228,685 common stock
options and warrants were excluded from the diluted EPS calculation, as their
effect was antidilutive.

     The following data shows the amounts used in computing earnings (loss) per
share and their effect on the weighted-average number of shares of dilutive
common share equivalents for the three months ended March 31, 2000 and 2001. The
amounts are rounded to the nearest thousand except for per share amounts.

Item 2. Management's Discussion and Analysis of Financial Condition and Results
        of Operations

     The following discussion is intended to assist in the understanding of
Mannatech's financial position and its results of operations for the three
months ended March 31, 2001 compared to the same period in 2000. The
Consolidated Financial Statements and related Notes should be referred to in
conjunction with this discussion. Unless stated otherwise, all financial
information presented below, throughout this report and in the Consolidated
Financial Statements and related Notes includes Mannatech and all of its
subsidiaries on a consolidated basis.

Overview

     Mannatech develops and sells proprietary nutritional supplements and
topical products in the United States, Canada, Australia, the United Kingdom and
Japan, through a worldwide network marketing system of approximately 237,000
active associates as of April 20, 2001, compared to approximately 269,000 active
associates as of March 9, 2000.

                                       6


     Mannatech's diluted earnings (loss) per share was ($0.01) for the three
months ended March 31, 2001 compared to ($0.03) per share in 2000. The net loss
for 2000 primarily related to the decrease in consolidated net sales and
incurring additional expenses related to international expansion into the United
Kingdom and Japan. The net loss for 2001 primarily related to a decrease in
consolidated net sales of $5.5 million partially offset by the curtailment of
certain operating expenses. However, in spite of the decrease in consolidated
net sales, income from operations for its North American operations remained the
same as compared to the comparable period in 2000.

     Beginning in February 2001, Mannatech increased its shipping fees charged
to its associates and in March increased some of the sale prices of its
products. In spite of the recent sales price increases, Mannatech believes the
negative trend in its net sales will continue into the first half of 2001. In
the future, Mannatech expects its international operations to account for an
increasing percentage of its consolidated net sales. The net sales by country as
a percentage of consolidated net sales are as follows:

              2000  ..............   77.3%       13.6%          7.7%        1.4%        --%      100.0%


     In the aggregate, net sales continue to decrease as compared to the same
period in 2000. Mannatech believes this decrease in net sales is due to a number
of factors including the following:

     .  its associates focusing on understanding the recent changes in the
        global compensation plans and how the changes may affect them;

     .  some of its associates exploring new competitive networking companies as
        another way to supplement their income;

     .  associates' concern about recent management changes; and

     .  concerns about the decline of Mannatech's stock price that, in part, may
        have resulted from unanticipated selling pressure.

     In its ongoing quest to provide products to consumers that help meet the
current demand for optimal health and wellness, Mannatech introduced a new
product, in October 2000 called ImmunoStart(TM), which helps trigger immune
responses. In March 2001, Mannatech introduced a chewable multi-vitamin for
children called Glyco-Bears(TM). Mannatech intends to introduce other new
products during 2001, which it hopes will further complement its current
products, help boost net sales and help satisfy the demand for optimal health
and wellness.

     Mannatech's revenues are primarily derived from sales of its products and
starter and renewal packs, which include some combination of its products and
promotional materials. The purchase of a starter or renewal pack allows the
associate to purchase products at wholesale prices and earn commissions.
Beginning May 26, 2001, Mannatech will introduce another program to help
increase its product sales. Under this new program, a consumer can submit a
member application rather than becoming an associate. A member does not receive
any commissions; however, a member is allowed to purchase Mannatech products at
95% of the suggested retail price or 86% of the suggested retail price for an
automatic order. To become a member, the consumer pays a one-time membership fee
of $10.00, which will be waived if the member places a product order at the time
they submit their application. Mannatech tries to offer comparable starter packs
in each country in which it does business; however, due to different regulatory
guidelines in each country not all of Mannatech's packs are offered in all
countries.

     Mannatech adopted Staff Accounting Bulletin No. 101 "Revenue Recognition in
Financial Statements" ("SAB 101") in the fourth quarter of 2000. Under SAB 101,
Mannatech is required to defer the recognition of revenues until the consumer
receives the products shipped. The adoption of SAB 101 resulted in a one-time
cumulative effect of accounting change of approximately $210,000, net of tax of
$126,000.

                                       7


     On average, the wholesale value of the nutritional and topical products
contained in each of Mannatech's starter and renewal packs is between 60% and
70% of the total wholesale value of the packs and the remainder of the total
wholesale value consists of various promotional materials and products.
Mannatech defers revenue received from the sale of its promotional packs to the
extent that the sales price is greater than the wholesale value of the
individual items included in such packs. The deferred revenue is amortized over
a twelve-month period. Total deferred revenue was approximately $691,000 at
December 31, 2000 and $866,000 at March 31, 2001.

     Mannatech compensates its associates by paying them commissions and
incentives, which are its most significant expense. The commission structure,
excluding some of the bonus programs, is designed not to materially exceed 42%
of commissionable net sales. In March 2001, Mannatech announced two new
incentive bonus programs for its associates. The Power Plan incentive bonus pays
associates for enrolling six All-Star associates and the Team incentive bonus
pays associates for meeting and maintaining certain purchasing levels in their
organizations. Mannatech plans to announce other changes to its worldwide
compensation plans for the 2002 fiscal year and continues to revise its training
programs for its associates. Mannatech believes the changes in the compensation
program will ultimately pay more commission incentives to the entry-level
associates faster. Changes to the compensation plan are not expected to change
the total commission paid as a percentage of commissionable net sales.
Commissions and incentives paid to associates are based on the following:

     .  associates' placement and position within the compensation plan;

     .  volume of their direct commissionable net sales;

     .  number of new enrolled associates; and

     .  achievement of certain levels to qualify for various incentive programs.

     In 2001, Mannatech believes its United States federal statutory tax rate
will remain at 34%. Mannatech expects to pay taxes in Australia at a statutory
tax rate of approximately 36% and in the United Kingdom at a statutory tax rate
of approximately 31%. Mannatech expects to pay taxes in Japan at a statutory tax
rate ranging between 42% and 48%. Mannatech also pays taxes in various state
jurisdictions at an approximate average effective tax rate of 3%. Due to its
international operations, a portion of Mannatech's income will be subject to
taxation in the countries in which it operates; however, it may receive foreign
tax credits that would reduce the amount of United States taxes owed. Mannatech
may not be able to use all of such foreign tax credits in the United States.
Mannatech may also incur net operating losses that may not be fully realizable.

Three months ended March 31, 2001 compared with the three months ended March 31,
2000

     Net Sales. Net sales decreased (13.9%) to $34.2 million for the three
months ended March 31, 2001 from $39.7 million for the comparable period in
2000. This decrease was primarily composed of the following:

     .  A $1.2 million increase from the sale of several new products introduced
        during the first three months of 2001 and the last nine months of 2000,
        including ImmunoStart(TM), Optimal Health Pack(TM) and GlycoBears(TM).

     .  A ($5.6) million decrease in existing product sales and other sales
        related items resulting from a decrease in the volume of products sold.

     .  A decrease of ($1.1) million from associate pack sales. Of this ($1.1)
        million decrease, approximately ($1.5) million resulted from an overall
        decrease in the number and dollars of associates packs sold to new
        associates. The decrease was partially offset by an increase of $0.4
        million of associate renewal packs sold; however, the number of
        associate renewal packs sold decreased compared to 2000. The decrease in
        the number of renewal packs sold was the result of the increase in the
        demand for the higher dollar packs. Mannatech continues to explore ways
        and strategies to increase associate pack and renewal pack sales.

                                       9


     Cost of Sales. Cost of sales decreased 17.4% to $5.7 million for the three
months ended March 31, 2001 from $6.9 million for the comparable period in 2000.
As a percentage of net sales, cost of sales decreased to 16.8% for the three
months ended March 31, 2001 from 17.4% for the comparable period in 2000. The
decrease in cost of sales as a percentage of net sales was primarily due to a
change in the product mix of finished goods sold and the 7% price increase for
our products, implemented in March 2001. The dollar amount decrease was
primarily due to a decrease in the volume of finished goods sold.

     Commissions. Commissions consist of payments to associates for sales
activity and downline growth. Commissions decreased (16.4%) to $13.8 million for
the three months ended March 31, 2001 from $16.5 million for the comparable
period in 2000. As a percentage of net sales, commissions decreased to 40.4% for
the three months ended March 31, 2001 from 41.6% for the comparable period in
2000. The dollar decrease was the direct result of a decrease in commissionable
net sales and a decrease in the number of active associates.

     Gross Profit. Gross profit decreased (9.8%) to $14.7 million for the three
months ended March 31, 2001 from $16.3 million for the comparable period in
2000. As a percentage of net sales, gross profit increased to 42.8% for the
three months ended March 31, 2001 from 41.0% for the comparable period in 2000.
These changes were primarily attributable to the factors described above.

     Selling and Administrative Expenses. Selling and administrative expenses
are a mixture of both fixed and variable expenses and include wages, bonuses,
shipping and freight and marketing expenses. Selling and administrative expenses
decreased (9.1%) to $9.0 million for the three months ended March 31, 2001 from
$9.9 million for the comparable period in 2000. As a percentage of net sales,
selling and administrative expenses increased to 26.4% for the three months
ended March 31, 2001 from 25.0% for the comparable period in 2000, which was the
result of the inability to reduce some of its fixed and semi-variable expenses.
The dollar decrease was primarily due to the following:

     .  a ($290,000) decrease in advertising, which was a result of not
        incurring various advertising expense in 2001 related to our
        subsidiary-Internet Health Group, Inc., which ceased operations on
        December 29, 2000;

     .  a decrease in freight cost of ($177,000); and

     .  a ($390,000) decrease in marketing expense, which was the result of
        Mannatech not continuing to expand into other countries in 2001.

     Other Operating Costs. Other operating costs include utilities,
depreciation, travel, office supplies and printing expenses. Other operating
costs decreased (17.6%) to $6.1 million for the three months ended March 31,
2001 from $7.4 million for the comparable period in 2000. As a percentage of net
sales, other operating costs decreased to 17.9% for the three months ended March
31, 2001 from 18.8% for the comparable period in 2000. The dollar decrease was
primarily due to the following:

     .  a decrease of ($841,000) related to variable expenses associated with a
        decline in net sales and the curtailment of certain operating expenses;

     .  a decrease of ($409,000) relating to a reduction in travel, accounting,
        legal and consulting fees partially offset by the increase in
        depreciation expense, which all related to Mannatech's recent expansion
        into various international counties; and

     .  a decrease of ($100,000) related to the reduction in certain
        nonessential research and development activities and a result of
        reorganizing the research and development department in the first
        quarter of 2001.

                                       10


     Interest Income. Interest income decreased (60.1%) to $97,000 for the three
months ended March 31, 2001 from $243,000 for the comparable period in 2000. As
a percentage of net sales, interest income decreased to 0.3% for the three
months ended March 31, 2001 from 0.6% for the comparable period in 2000. The
dollar decrease was primarily due to using investments to fund its recent
international expansion.

     Interest Expense. Interest expense decreased (62.5%) to $9,000 for the
three months ended March 31, 2001 from $24,000 for the comparable period in
2000. As a percentage of net sales, interest expense remained the same at 0.0%
for both the three months ended March 31, 2001 and the comparable period in
2000. The dollar decrease was primarily due to the repayment of existing leases.

     Other Expense, Net. Other expense consists of foreign currency translation
adjustments and miscellaneous non-operating items. Other expense increased 2.7%
to $115,000 for the three months ended March 31, 2001 from $112,000 for the
comparable period in 2000. As a percentage of net sales, other expense remained
the same at 0.3% for both the three months ended March 31, 2001 and for the
comparable period in 2000. For the three months ended March 31, 2001, other
expense consisted primarily of currency exchange losses due to translation
fluctuations. For the three months ended March 31, 2000, other expense consisted
of approximately $36,000 in certain tax penalties and approximately $63,000 in
currency exchange losses due to translation fluctuations.

     Income Tax Benefit. Income tax benefit was $212,000 for the three months
ended March 31, 2001 and $357,000 for the comparable period in 2000. Mannatech's
effective tax rate increased to 40.6% for the three months ended March 31, 2001
from 35.8% for the comparable period in 2000. Mannatech's effective tax rate
increased primarily as a result of the effect of various nondeductible expenses
in the three months ended March 31, 2001 as compared to the comparable period in
2000.

     Cumulative Effect of Accounting Change. In the fourth quarter of 2000,
Mannatech adopted Staff Accounting Bulletin No. 101 " Revenue Recognition in
Financial Statements" ("SAB 101"), which resulted in a one-time charge of
$210,000, net of tax of $126,000 for the cumulative effect of the accounting
change. SAB 101 required Mannatech to defer the recognition of revenues until
the consumers receive the products shipped.

     Net Loss. Net loss decreased (66.9%) to ($309,000) for the three months
ended March 31, 2001 from ($850,000) for the comparable period in 2000. As a
percentage of net sales, net loss decreased to (0.9%) for the three months ended
March 31, 2001 from (2.1%) for the comparable period in 2000. The dollar
decrease was due to net sales decreasing by (13.9%), offset by the curtailment
of various operating expenses, no longer incurring expenses related to its
Internet subsidiary and international expansion.

Liquidity and Capital Resources

     Mannatech's primary capital requirement is to fund working capital that
historically has been financed through its operations. Mannatech's working
capital increased to $7.6 million as of March 31, 2001 from $7.3 million at
December 31, 2000. In 2000, Mannatech invested approximately $4.4 million in its
expansion into Japan and $4.1 million to fund operations for Internet Health
Group, Inc. In 2001, Mannatech funded the payments of the various severance
packages for some of its executive officers and reported a decrease in net sales
of 13.9%. Mannatech plans to continue to fund its 2001 working capital through
its operations.

     In March and August 1998, Mannatech entered into two capital leases with
principal amounts of $631,000 and $841,000, respectively. These capital leases
bear interest at 9.3%, are collateralized by the leased assets and are payable
in thirty-six monthly installments. In July 1998, Mannatech entered into an
unsecured note payable with a finance company to finance its three-year product
liability insurance premium. The initial principal amount of this note was
$435,670, the interest rate was 8.0% and monthly installments were due through
December 2000. In March 2001, Mannatech entered into an eight month, unsecured
note payable with a finance company to finance its one-year directors and
officers liability insurance premium. The initial principal amount of this note
was $186,750, bears interest at a rate of 9.15% and is due in monthly
installments through December 2001.

                                       11


     Net cash used in operating activities was $1.9 million for the three months
ended March 31, 2000 compared to $400,000 for the three months ended March 31,
2001. For the first three months ended March 31, 2000, operating activities
included a net loss and an increase in inventory and prepaid expenses and a
decrease in payables and accrued expenses. For the first three months ended
March 31, 2001, operating activities included a net loss combined with a
decrease in payables.

     Net cash provided by (used in) investing activities was ($767,000) for the
three months ended March 31, 2000 compared to $73,000 for the three months ended
March 31, 2001. For the first three months ended March 31, 2000, investing
activities consisted of $1.5 million related to purchases of computer hardware
and software and the build out of the Japan facility offset by $636,000 maturing
of investments. For the first three months ended 2001, investing activities
consisted of $73,000 for purchases of property and equipment offset by the
repayment of notes receivable due from shareholders of $143,000.

     Net cash provided by (used in) financing activities was $64,000 for the
three months ended March 31, 2000 compared to ($1.6) million for the three
months ended March 31, 2001. For the first three months ended March 31, 2000,
financing activities consisted of receiving $243,000 related to the exercise of
175,000 stock options at prices per share ranging from $1.35 to $2.00 offset by
the repayment of capital leases and notes payable of $179,000. For the first
three months ended March 31, 2001, financing activities consisted of the payment
of cash overdrafts of $1.4 million and purchasing 76,963 shares of common stock
from Mr. Charles Fioretti totaling $83,333 related to the lock-up and repurchase
agreement with him. Under the terms of this agreement, Mannatech is also
required through February 3, 2002, to purchase $83,333.33 worth of his common
stock each month valued at 90% of the fair market price. In exchange for the
repurchase of his stock, Mr. Charles Fioretti will be prohibited from trading
his shares of Mannatech's common stock though March 2, 2002, unless prior
approval is obtained from the Board of Directors.

     Mannatech believes its existing capital resources, bank borrowings and
suspension of dividend payments to shareholders, should be adequate to fund its
operations for at least the next twelve months. Mannatech has no present
commitments or agreements with respect to any acquisitions or purchases of
manufacturing facilities or new technologies. However, as a result of the recent
resignation of Mr. Anthony Canale and Ms. Deanne Varner, Mannatech is required
to pay them in the future an aggregate amount of $500,000, per year through
2003, respectively. In addition, in August 2000, the Board of Directors approved
a one-year plan to repurchase up to one-million dollars worth of Mannatech's
common stock, on the open market, to help stabilize the price of the stock due
in part to significant selling of the stock in the open market. Any future
changes in Mannatech's operations could consume available capital resources
faster than anticipated. Mannatech's capital requirements depend on numerous
factors, including:

     .  the introduction of new products;

     .  change in the number of associates and the retention of the current
        associate base; and

     .  research and development efforts.

     If existing capital resources are insufficient to meet Mannatech's capital
requirements, Mannatech would be required to raise additional funds, which it
cannot assure will be available on favorable terms, if at all.

Recent Financial Accounting Standards Board Statements

     In June 1998, the Financial Accounting Standards Board issued Financial
Accounting Standard No. 133, "Accounting for Derivative, Instruments and Hedging
Activities" ("FAS 133"). This statement establishes accounting and reporting
standards for hedging activities and derivative financial instruments, including
certain derivative financial instruments embedded in other contracts. In June
1999, the Financial Accounting Standards Board issued Financial Accounting
Standard No. 137, which defers the effective date of FAS 133 to fiscal years
beginning after June 15, 2000. In June 2000, the Financial Accounting Standards
Board issued Financial Accounting Standard No. 138, "Accounting for Certain
Derivative Instruments and Certain Hedging Activities," which addressed certain
issues causing implementation difficulties. The adoption of this statement did
not have nor is expected to have any future material impact on Mannatech's
consolidated financial position, results of operations or cash flows.

Forward-Looking Statements

     Some of our statements under "Management's Discussion and Analysis of
Financial Condition and Results of Operations," "Quantitative and Qualitative
Disclosures about Market Risk," "Other Information" and the Notes to

"forward-looking statements" within the meaning of Section 27A of the Securities
Act of 1933, as amended, Section 21E of the Securities Exchange Act of 1934 and
the Private Litigation Act of 1995. Opinions, forecasts, projections, guidance
or other statements other than statements of historical fact are considered
forward-looking statements. These forward-looking statements are subject to
certain events, risks and uncertainties that may be outside Mannatech's control.
Some of these forward-looking statements include statements regarding:

     .  management's plans, objectives and budgets for its future operations and
        future economic performance;

     .  capital budget and future capital requirements;

     .  meeting future capital needs;

     .  the level of future expenditures;

     .  impact of foreign currency translations;

     .  impact of recent accounting pronouncements;

     .  the outcome of regulatory and litigation matters; and

     .  the assumptions described in this report underlying such forward-looking
        statements.

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

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

     .  future product development and manufacturing costs;

     .  recent and future changes in Mannatech's global incentive plans;

     .  timely development and acceptance of new products;

     .  the markets for Mannatech's domestic and international operations;

     .  the impact of competitive products and pricing;

     .  the political, social and economic climate in which Mannatech conducts
        its operations; and

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

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

as all of the forward-looking statements contained herein speak only as of the
date of this report.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

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

     Mannatech is exposed to certain other market risks, including changes in
currency exchange rates as measured against the United States dollar. The value
of the United States dollar may affect Mannatech's financial results. Changes in
exchange rates may positively or negatively affect its financial results, as
expressed in United States dollars. When the United States dollar increases
against currencies in which products are sold or a weakening exchange rate
against currencies in which Mannatech incurs costs, net sales or costs may be
adversely affected. Mannatech has established policies, procedures and internal
processes governing the management of its market risks and the use of any
financial instruments to manage its exposure to such risks. The sensitivity of
earnings and cash flows to variability in currency exchange rate is assessed by
applying an appropriate range of potential rate fluctuations to Mannatech's
assets, obligations and projected transactions denominated in foreign currency.
Based upon its overall currency rate exposure at March 31, 2001, Mannatech does
not believe that its exposure to currency exchange rate fluctuations will have a
material impact on its consolidated financial position, results of operations or
cash flows. The foreign currencies in which Mannatech has exposure to foreign
currency exchange rate risk include Australia, the United Kingdom and Japan. The
high and low exchange rates to the United States dollar, for each of these
countries, for the three months ended March 31, 2001 are as follows:

               Country/Currency                     High       Low
               ----------------                   --------   --------
               Australia/Dollar.................  $0.57220   $0.48450
               United Kingdom/British Pound.....  $1.51030   $1.41480
               Japan/Yen........................  $0.00880   $0.00791

     Given the uncertainty of the exchange rate fluctuation against the United
States dollar, Mannatech cannot determine the dollar effect, if any, of the
fluctuation on future business, product pricing, and results of operations or
financial condition. All statements other than historical information
incorporated in this Item 3 are considered forward-looking statements. The
actual impact of future market changes may differ materially due to, among other
things, factors discussed in this report.
