            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

NOTE 1  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Mannatech, Incorporated (the "Company") was incorporated in the State of
Texas on November 4, 1993, as Emprise International, Inc.  Effective October 25,
1995, the Company changed its name to Mannatech, Incorporated.  The Company,
located in Coppell, Texas, develops and sells high-quality, proprietary
nutritional supplements, topical products and weight-management products
primarily through a network marketing system operating in the United States,
Canada, Australia, the United Kingdom and Japan. Independent associates
("Associates") purchase products at wholesale, for the primary purpose of
selling to retail consumers or for personal consumption. Associates earn
commissions on their downline growth and sales volume.  In June 2001, the
Company introduced its member program specifically designed for consumers to
purchase the Company's high-quality products for personal consumption and not
participate in its various incentive programs.

     The Company's nine wholly-owned subsidiaries are as follows:

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

Principles of Consolidation

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

Revenue Recognition

     The Company's revenues consist of sales from products, sales from starter
and renewal packs and shipping fees. Substantially all product sales are made to
Associates at published wholesale prices. Product sales are also made to members
at published discounted retail prices. Net sales include a reserve for estimated
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

                                       4


of 2000. As a result of adopting SAB 101, the Company has restated its 2000
quarterly financial information and recorded a one-time charge of $210,000, net
of tax of $126,000 for the cumulative effect of this accounting change at
January 1, 2000. Beginning in 2000, the Company defers all of its revenues until
the consumer receives the products shipped.

     The Company also defers a portion of its revenue received from sales of
starter and renewal packs, which are in excess of the average 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 $628,000 at
December 31, 2000 and June 30, 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 consumers, as revenue.  The Company records in-bound
freight and shipping costs as a part of cost of sales and records shipping and
handling costs associated with shipping products to its consumers as selling and
administrative expenses. Total shipping and handling costs included in selling
and administrative expenses was approximately $1.5 million and $2.4 million for
the three months ended June 30, 2001 and 2000, respectively and $3.1 million and
$4.5 million for the six months ended June 30, 2001 and 2000, respectively.

Earnings Per Share

     The Company calculates earnings (loss) per share pursuant to Statement of
Financial Accounting Standards No. 128, "Earnings Per Share" ("FAS 128").  FAS
128 requires dual presentation of basic and diluted earnings (loss) per share
("EPS") on the face of the consolidated statement of operations for all entities
with complex capital structures and requires a reconciliation of the numerator
and denominator of the basic EPS computation to the numerator and denominator of
the diluted EPS computation. Basic EPS calculations are based on the weighted-
average number of common shares outstanding during the period, while diluted EPS
calculations are calculated using the weighted-average number of common shares
and dilutive common share equivalents outstanding during each period. At June
30, 2000, all of the 2,028,300 common stock options were excluded from the
diluted EPS calculation and at June 30, 2001, all of the 2,781,259 common stock
options and 213,333 warrants were excluded from the diluted EPS calculation, as
their effect was antidilutive.

     The following data shows the amounts used in computing earnings (loss) per
share and their effect on the weighted-average number of shares of dilutive
common share equivalents for the three months ended June 30, 2000 and 2001. The
amounts are rounded to the nearest thousand except for per share amounts.

  NOTE 4  COMMITMENTS AND CONTINGENCIES

     In the fourth quarter of 2000, Mr. Anthony Canale resigned and in the
second quarter of 2001, Ms. Deanne Varner, Mr. Charles Fioretti and Mr. Patrick
Cobb resigned as executive officers of the Company. As a result, the Company
entered into a separation agreement with each of them.  Under the terms of their
agreements, the executives are bound by certain non-compete and confidentiality
clauses and the Company agreed to pay them an aggregate amount of $1.9 million
in 2001, $1.6 million in 2002, $850,000 in 2003 and $150,000 in 2004. The
payments consist of various charges including compensation related to their
cancellation of their employment agreements, accrued vacation, health insurance
and automobile expenses. The Company also agreed to grant Mr. Canale 213,333
warrants, Ms. Varner a total of 163,333 stock options and Mr. Patrick Cobb a
total of 60,000 stock options, all at exercise prices ranging from $1.75 to
$4.00. The warrants and stock options vest on the date they were granted and are
exercisable for ten years. The Company recorded a charge for all of these
separation agreements of which $2.9 million and $950,000 remained unpaid as of
June 30, 2001 and December 31, 2000, respectively.

NOTE 5      RECENT ACCOUNTING PRONOUNCEMENTS

     In July 2001, the Financial Accounting Standards Board issued Statements of
Financial Accounting Standards No. 141 ("SFAS 141") "Business Combinations" and
No. 142 ("SFAS 142") "Goodwill and Other Intangibles Assets."

     SFAS 141 supercedes Accounting Principles Board Opinion No. 16 "Business
Combinations." The most significant changes made by SFAS 141 are that it
requires the purchase method of accounting be used for all business combinations
initiated after June 30, 2001, establishes specific criteria for recognition of
certain intangibles assets separately from goodwill and requires the immediate
write-off of unallocated negative goodwill.

     SFAS 142 supercedes Accounting Principles Board Opinion No. 17 "Intangible
Assets." SFAS 142 is effective for fiscal years beginning after December 15,
2001. SFAS 142 prohibits goodwill and indefinite lived intangible assets from
being amortized and requires them to be annually tested for impairment at each
reporting unit level.  In addition, SFAS 142 removes the limitation of forty
years for the useful lives of finite intangible assets.

     The Company believes SFAS 141 and SFAS 142 will have no effect on its
consolidated financial positions, results of operations and cash flows.

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

     The following discussion is intended to assist in the understanding of
Mannatech's financial position and its results of operations for the three and
six months ended June 30, 2001 compared to the same periods in 2000. The
Consolidated Financial Statements and related Notes should be referred to in
conjunction with this discussion. Unless stated otherwise, all financial
information presented below, throughout this report and in the Consolidated
Financial Statements and related Notes includes Mannatech and all of its
subsidiaries on a consolidated basis.

Overview

     Mannatech develops and sells high-quality, proprietary nutritional
supplements, topical products and weight-management products primarily through a
worldwide network marketing system operating in the United States, Canada,
Australia, the United Kingdom and Japan. Currently Mannatech has approximately
217,000 active associates as of June 30, 2001 compared to approximately 267,000
active associates as of June 30, 2000. Mannatech defines an active associate as
having purchased products in the last twelve months.  In June 2001, Mannatech
introduced its new member program specifically designed for consumers to
purchase its high-quality proprietary products for personal consumption and not
participate in its various incentive programs.

     Mannatech's earnings (loss) per share was ($0.10) for the six months ended
June 30, 2001 compared to ($0.06) per share in 2000. The net loss for 2001
totaling ($2.4 million) primarily related to recording a one-time charge of $3.4
million for the various severance expenses primarily related to the resignation
of three of its former executives who held employment agreements coupled with
the decrease in net sales directly attributed to the 19% decrease in its active
associate base. For the six months ended June 30, 2001, Mannatech would have
reported Income before taxes, exclusive of the one-time severance charge of $3.4
million of $660,000. The net loss for 2000 totaling ($1.5 million) primarily
related to the decrease in net sales, incurring $2.0 million in expenses related
to international expansion into the United Kingdom and Japan and funding
operations for the Internet subsidiary - Internet Health Group, Inc, which
discontinued operations on December 29, 2000.

     Beginning in February 2001, Mannatech increased its shipping fees charged
to its consumers and in March increased the sale prices of some of its finished
goods. This price increase was Mannatech's first since its inception. In order
to help stabilize operations and return to a growth position, Mannatech
introduced its member program and announced the hiring of new general managers
for both its Australia and Japan operations. Mannatech also implemented some new
incentive programs specifically designed to reward its entry-level associates
faster, increase its active associate base and boost net sales. Net sales by
country, as a percentage of consolidated net sales, including the Japan
operations, which began operations on June 26, 2000, are as follows:

                                       7




       Six months ended June 30,        U.S.      Canada     Australia      U.K.        Japan        Total
       --------------------------     --------  ----------  -----------  ----------  -----------  ------------
                                                                                
              2001...............        77.6%       14.2%         3.3%        1.0%         3.9%        100.0%
              2000...............        78.3%       13.2%         6.5%        1.4%         0.6%        100.0%


     Mannatech intends to continue to provide the highest quality of products to
its consumers that will help them to achieve optimal health and wellness. In
March 2001, Mannatech introduced a new chewable multi-vitamin for children
called Glyco-Bears(TM). Mannatech believes the chewable vitamin will help
supplement children's diets and help them optimize their health and wellness.
Mannatech also intends to introduce other new products during 2001, which will
further complement its current list of high-quality, proprietary products, help
increase net sales and aid in achieving optimal health and wellness.

     Mannatech primarily derives its revenues from sales of its products and
starter and renewal packs. Starter and renewal packs include some combination of
Mannatech's proprietary products and promotional materials. An associate who
purchases a starter or renewal pack may purchase Mannatech's high-quality
proprietary products at wholesale prices and earn various incentives.  In June
2001, Mannatech introduced its member program, which allows a member to purchase
its high-quality proprietary products at 95% of the suggested retail price or
86% of the suggested retail price for an automatic order. Mannatech offers
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.

     On average, the wholesale value of the nutritional and topical products
contained in each of Mannatech's starter and renewal packs are between 60% and
100% of the total wholesale value of the packs and the remainder of the total
wholesale value, if any, consists of various promotional materials. Mannatech
defers revenue received from the sale of its associate packs to the extent that
the sales price is greater than the wholesale value of the individual items
included in such packs. Deferred revenue is then amortized over a twelve-month
period. Total deferred revenue was approximately $691,000 at December 31, 2000
and $628,000 at June 30, 2001.

     Mannatech compensates its associates by paying them commissions and
incentives, which are its most significant expense. The commission structure,
excluding some of the incentive 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 believes these incentive programs will
ultimately pay more commissions to the entry-level associate faster. Mannatech
also plans to announce other changes to its worldwide compensation plan for the
2002 fiscal year; however,  changes to its compensation plan are not expected to
significantly 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 also pays taxes in various state jurisdictions at
an approximate average effective tax rate of 3%.  Mannatech expects to pay taxes
in Australia, the United Kingdom and Japan at statutory tax rates ranging from
31% to 42%. The payment of such foreign taxes could result in foreign tax
credits that would reduce the amount of United States taxes owed; however,

                                       8


Mannatech may not be able to fully-utilize all of such foreign tax credits in
the United States. Mannatech has also incurred net operating losses from its
Japan subsidiary that may not be fully realizable in the future.

Three months ended June 30, 2001 compared with the three months ended June 30,
2000

     Net sales. Net sales decreased (16.7%) to $32.5 million for the three
months ended June 30, 2001 from $39.0 million for the comparable period in 2000.
This decrease was primarily composed of the following:

    .  A decrease of 19% in the active associate base.  An active associate is
       defined as having purchased packs or products in the last twelve months.

    .  The decrease was partially offset by a 7% increase in the sales prices of
       finished goods implemented in March 2001, a $2.3 million increase from
       opening its Japan operations on June 26, 2000 and the sale of several new
       products including ImmunoStart(TM), Optimal Health Pack(TM) and

     Cost of sales. Cost of sales decreased (14.7%) to $5.8 million for the
three months ended June 30, 2001 from $6.8 million for the comparable period in
2000. As a percentage of net sales, cost of sales increased to 17.9% for the
three months ended June 30, 2001 from 17.4% for the comparable period in 2000.
The increase in cost of sales as a percentage of net sales was primarily due to
a write-off of some outdated promotional materials totaling $381,000 and a
change in the product mix of finished goods sold partially offset by the 7%
price increase for some of its finished goods, implemented in March 2001. The
dollar decrease was primarily due to a decrease in the volume of finished goods
sold partially offset by the write-off of certain outdated promotional materials
totaling $381,000.

     Commissions. Commissions consist of payments to associates for their sales
activity and downline growth. Commissions decreased (19.9%) to $12.5 million for
the three months ended June 30, 2001 from $15.6 million for the comparable
period in 2000. As a percentage of net sales, commissions decreased to 38.4% for
the three months ended June 30, 2001 from 39.8% for the comparable period in
2000. The dollar decrease was the direct result of a decrease in commissionable
net sales resulting from a 19% decrease of active associates partially offset by
the payment of commissions for two new incentive programs called the Power Plan
incentive bonus and Team incentive bonus.

     Gross profit. Gross profit decreased (15.0%) to $14.2 million for the three
months ended June 30, 2001 from $16.7 million for the comparable period in 2000.
As a percentage of net sales, gross profit increased to 43.7% for the three
months ended June 30, 2001 from 42.8% for the comparable period in 2000. These
changes were primarily attributable to the factors described above.

     Selling and administrative expenses. Selling and administrative expenses
are a mixture of both fixed and variable expenses and include compensation,
shipping and freight and marketing expenses. Selling and administrative expenses
decreased (15.6%) to $7.6 million for the three months ended June 30, 2001 from
$9.0 million for the comparable period in 2000. As a percentage of net sales,
selling and administrative expenses increased slightly to 23.3% for the three
months ended June 30, 2001 from 23.0% 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 decrease of ($531,000) in compensation and benefits due to the
        reduction in the current head count including the resignation of four
        executives;

     .  a decrease of ($651,000) in freight cost resulting from a decrease in
        net sales; and

     .  a decrease of ($231,000) in marketing expense, which was the result of
        hosting various preopening events for its new Japan operations in June
        2000.

     Other operating costs. Other operating costs include utilities,
depreciation, travel, office expenses and printing expenses. Other operating
costs decreased (30.4%) to $5.5 million for the three months ended June 30, 2001
from $7.9 million for the comparable period in 2000. As a percentage of net
sales, other operating costs decreased to 17.0% for the three months ended June
30, 2001 from 20.4% for the comparable period in 2000. The decrease was
primarily due to the following:

     .  a decrease of ($381,000) related to variable expenses associated with
        the decline in net sales and the curtailment of certain operating
        expenses;

     .  a decrease of ($1.2 million) relating to the reduction in long-distance
        telephone expenses, postage, consulting and international travel related
        to the international expansion which was substantially completed in
        2000;

     .  a decrease of ($505,000) related to the Gryphon lawsuit settlement
        recorded in the prior year and the completion of several projects by
        outside consultants;

     .  a decrease of ($107,000) related to receiving a property tax abatement
        for our corporate offices; and

                                       10


     .  a decrease of ($200,000) from the prior year related to the buyout of
        Ray Robbins last remaining incentive agreement in 2000, which was
        initially canceled in July 1999.

     Severance expenses related to former executives.  In the second quarter of
2001, management entered into three separation agreements with former executives
who had employment agreements for a one-time charge of $3.4 million. The $3.4
million consisted of compensation related to the cancellation of their
employment agreements, accrued vacation, health insurance and automobile
expenses that will be paid to the former employees at various times through
2004.

     Write-off of fixed asset. In the second quarter of 2000, management
determined its Internet subsidiary Internet Health Group, Inc's fixed asset
having a book value of $870,000 was impaired and should be written off. The
write-off was a result of the continuation of the poor performance of the
subsidiary, which discontinued operations as of December 29, 2000.

     Interest income. Interest income decreased (67.0%) to $59,000 for the three
months ended June 30, 2001 from $179,000 for the comparable period in 2000. As a
percentage of net sales, interest income decreased to 0.2% for the three months
ended June 30, 2001 from 0.5% for the comparable period in 2000. The dollar
decrease was primarily due to using investments to fund current year operations.

     Interest expense. Interest expense decreased (65.0%) to $7,000 for the
three months ended June 30, 2001 from $20,000 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 June 30, 2001 and the comparable period in 2000. The
dollar decrease was primarily due to the pay off of an existing note and a
capital lease.

     Other income (expense),net. Other income (expense), net consists of foreign
currency translation adjustments relating to its United Kingdom and Australia
operations and miscellaneous non-operating items. Other income (expense), net

the comparable period in 2000. As a percentage of net sales, other income
(expense), net increased to 0.0% for the three months ended June 30, 2001 from
(0.1%) for the comparable period in 2000.  For the three months ended June 30,
2001 and 2000, other income (expense), net consisted primarily of currency
translation adjustments.

     Income tax benefit. Income tax benefit was $165,000 for the three months
ended June 30, 2001 and $271,000 for the comparable period in 2000. Mannatech's
effective tax rate decreased to 7.4% for the three months ended June 30, 2001
from 28.6% for the comparable period in 2000. Mannatech's effective tax rate
decreased primarily as a result of the establishment of a valuation allowance
for the net operating losses from its Japan subsidiary.

     Cumulative effect of accounting change, net of tax. 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 increased 206.5% to ($2.1) million for the three months
ended June 30, 2001 from ($677,000) for the comparable period in 2000. As a
percentage of net sales, the net loss increased to (6.4%) for the three months
ended June 30, 2001 from (1.7%) for the comparable period in 2000. The dollar
increase was due to recording a one-time charge of $3.4 million related to the
resignation of three executives, a decrease in net sales of (16.7%) due to the
19% decrease in the active associate base, partially offset by the curtailment
of various operating expenses and no longer incurring expenses related to its
Internet subsidiary and international expansion. For the three months ended June
30, 2001, Mannatech would have reported Income before income taxes of $1.2
million exclusive of the one-time charge of $3.4 million.

Six months ended June 30, 2001 compared with the six months ended June 30, 2000

     Net sales. Net sales decreased (15.2%) to $66.7 million for the six months
ended June 30, 2001 from $78.7 million for the comparable period in 2000.  This
decrease was primarily composed of the following:

                                       11


     .  A decrease of 19% in the active associate base. An active associate is
        defined as having purchased packs or products in the last twelve months.

     .  This decrease was partially offset by a 7% sales price increase in some
        of its finished goods implemented in March 2001, a $3.7 million increase
        from opening Japan on June 26, 2000 and the sale of several new products
        including ImmunoStart(TM), Optimal Health Pack(TM) and GlycoBears(TM).

     Cost of sales. Cost of sales decreased (16.1%) to $11.5 million for the six
months ended June 30, 2001 from $13.7 million for the comparable period in 2000.
As a percentage of net sales, cost of sales decreased to 17.3% for the six
months ended June 30, 2001 from 17.4% for the comparable period in 2000. The
slight 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 some of its finished goods, 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 (18.1%) to $26.3 million for
the six months ended June 30, 2001 from $32.1 million for the comparable period
in 2000. As a percentage of net sales, commissions decreased to 39.4% for the
six months ended June 30, 2001 from 40.7% for the comparable period in 2000. The
dollar decrease was the direct result of a decrease in commissionable net sales
and a 19% decrease in active associates partially offset by the payment of two
new incentive programs called the Power Plan incentive bonus and Team incentive
bonus.

     Gross profit. Gross profit decreased (12.4%) to $28.9 million for the six
months ended June 30, 2001 from $33.0 million for the comparable period in 2000.

selling and administrative expenses increased to 24.9% for the six months ended
June 30, 2001 from 24.1% for the comparable period in 2000, which was the result
of the inability to reduce some of the fixed and semi-variable expenses.  The
dollar decrease was primarily due to the following:

     .  a decrease of ($584,000) in compensation and benefits related to a
        reduction in the current head count including the resignation of various
        executives;

     .  a decrease of ($828,000) in freight cost resulting from a decrease in
        net sales;

     .  a decrease of ($676,000) in marketing expense, which was the result of
        hosting various preopening events for its Japan operations in June 2000;
        and

     .  a decrease of ($252,000) in advertising due to the discontinuance of
        certain advertising and no longer incurring advertising expense related
        to the Internet subsidiary - Internet Health Group, Inc, which
        discontinued operations on December 29, 2000.

sales, other operating costs decreased to 17.5% for the six months ended June
30, 2001 from 19.5% for the comparable period in 2000. The percentage decrease
was the result of management making a concerted effort to curtail expenses. The
dollar decrease was primarily due to the following:

     .  a decrease of ($1.6 million) related to variable expenses associated
        with a decrease in net sales and the curtailment of certain operating
        expenses;

                                       12


     .  a decrease of ($2.0 million) in expenses related to travel, consulting,
        postage and telephone expenses incurred in the prior year related to the
        expansion into the United Kingdom and Japan;

     .  a decrease of ($200,000) from the prior year related to the buyout of
        Ray Robbins last remaining incentive agreement in 2000, which was
        initially canceled in July 1999;

     .  a decrease of ($105,000) related to license fees paid to a third party
        for the Internet subsidiary, which discontinued operations on December
        29, 2000;

     .  partially offset by an increase of $317,000 in depreciation and
        professional fees related to our recent expansion into Japan.

     Severance expenses related to former executives.  In the second quarter of
2001, management entered into three separation agreements with the former

compensation related to the cancellation of their employment agreements, accrued
vacation, health insurance and automobile expenses that will be paid to the
former employees at various times through 2004.

          Financing activities        ($1.7 million)            ($65,000)


     Operating activities. For the six months ended June 30, 2000, operating
activities primarily related to international expansion into the United Kingdom
and Japan, which resulted in a net loss of ($1.5 million) combined with an
increase in inventory of ($1.5 million), prepaids of ($372,000) partially offset
by an increase in payables of $1 million. For the six months ended June 30,
2001, operating activities primarily related to a one-time charge of $3.4
million related to the resignation of three executives, which resulted in a net
loss of ($2.4 million) combined with a decrease in payables and accrued expenses
of ($300,000), partially offset by a decrease in inventories of $762,000 due to
the closing of the Internet subsidiary and completion of its planned
international expansion.

     Investing activities. For the six months ended June 30, 2000, investing
activities consisted of purchases of computer hardware and software and the
build out of the Japan facility totaling $3.4 million, partially offset by the
maturing of investments of $1.4 million. The investments were primarily used to
fund the expansion into Japan. For the six months ended June 30, 2001, investing
activities consisted of purchases of property and equipment totaling $493,000
for the data warehouse software project, partially offset by the repayment of
notes receivable due from shareholders of $137,000.

     Financing activities. For the six months ended June 30, 2000, financing
activities consisted of the payoff and repayment of various capital leases and
notes payable totaling $359,000, partially offset by the receipt of $294,000
related to the exercise of 210,700 stock options at prices per share ranging
from $1.35 to $2.00. For the six months ended June 30, 2001, financing
activities consisted of the payment of cash overdrafts of $1.0 million and
repurchasing 369,397 shares of common stock from Mr. Charles Fioretti totaling
$406,000 pursuant to the lock-up and repurchase agreement with him. Under the
terms of his agreement, Mannatech is required through February 3, 2002, to
purchase $83,333.33 worth of Mr. Charles Fioretti's common stock each month
valued at 90% of the current fair market price. In exchange for the repurchase
of his stock, Mr. Charles Fioretti is prohibited from trading his shares of
Mannatech common stock through March 2, 2002, unless prior approval is obtained
from the Board of Directors.

     Mannatech believes its existing liquidity, capital resources and bank
borrowings, coupled with the continuation of the suspension of dividend payments
to shareholders should be adequate to fund its business operations and
commitments for at least the next twelve months including the following:

        .  In March 2001, Mannatech committed to fund up to $1 million to
           redevelop its core software database application onto a more easily
           maintainable architecture, which will also expand the information
           available to its associates using its corporate website. This
           project, known as the data warehouse project, is scheduled to be
           substantially complete by the winter of 2001.

                                       14


        .  Funding the payments related to the recent resignations of
           Mr. Anthony Canale, Ms. Deanne Varner, Mr. Charles Fioretti
           and Mr. Patrick Cobb. Under the terms of the various separation
           agreements, Mannatech is required to pay, in the future, an aggregate
           amount of $2.9 million, of which $1.8 million will be paid over the
           next twelve-months.

        .  Funding the payments of its annual insurance premiums, totaling
           $900,000, which Mannatech has historically funded over ten monthly
           installments payable to various finance companies.

     Mannatech has no other present commitments or agreements with respect to
any acquisitions or purchases of manufacturing facilities. Mannatech believes
any future changes in its operations may consume available capital resources
faster than anticipated and its existing capital requirements depends on
numerous factors, including:

        .  the introduction of new high-quality proprietary products;

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

        .  research and development efforts.

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

Recent Financial Accounting Standards Board Statements

     In 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 it expected to have, any future material impact on Mannatech's
consolidated financial position, results of operations or cash flows.

     In July 2001, the Financial Accounting Standards Board issued Statements of
Financial Accounting Standards No. 141 ("SFAS 141") "Business Combinations" and
No. 142 ("SFAS 142") "Goodwill and Other Intangibles Assets."

     SFAS 141 supercedes Accounting Principles Board Opinion No. 16 "Business
Combinations." The most significant changes made by SFAS 141 are that it
requires the purchase method of accounting be used for all business combinations
initiated after June 30, 2001, establishes specific criteria for recognition of
certain intangibles assets separately from goodwill and requires the immediate
write-off of unallocated negative goodwill.

     SFAS 142 supercedes Accounting Principles Board Opinion No. 17 "Intangible
Assets." SFAS 142 is effective for fiscal years beginning after December 15,
2001. SFAS 142 prohibits goodwill and indefinite lived intangible assets from
being amortized and requires them to be annually tested for impairment at each
reporting unit level.  In addition, SFAS 142 removes the limitation of forty
years for the useful lives of finite intangible assets.

     Mannatech believes SFAS 141 and SFAS 142 will have no effect on its
consolidated financial positions,  results of operations or cash flows.

                                       15


Outlook

     Mannatech believes its outlook for the remainder of 2001 and looking
forward into 2002 will be contingent upon the success of retaining its current
associate base, its ability to introduce new high-quality, proprietary products,
expanding its international sales to support the operations of its international
subsidiaries, its ability to minimize any disruption caused by the recent
resignation of former executives and effectively communicate the impact of the
changes in its compensation plans to its associates.

     Mannatech believes it has refocused its associate's attentions from the
recent management changes and international expansion back to the core business
of selling.  Mannatech also believes it has developed a plan to help stabilize
its associate base and return to a growth position operating in the nutritional
supplements industry, which helps to provide optimal health and wellness.

     .  impact of recent accounting pronouncements;

     .  the outcome of regulatory and litigation matters; and

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

Item 3.  Quantitative and Qualitative Disclosures About Market Risk

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

     Mannatech is exposed to certain other market risks, including changes in
currency exchange rates as measured against the United States dollar. The value
of the United States dollar may affect Mannatech's financial results. Changes in
exchange rates may positively or negatively affect its financial results, as
expressed in United States dollars. When the United States dollar increases
against currencies in which products are sold or when the exchange rate weakens
against currencies in which Mannatech incurs costs, net sales or costs may be
adversely affected.

     Mannatech has established certain policies, procedures and internal
processes, which it believes will help monitor any significant market risks.
Currently, Mannatech does not use any financial instruments to manage its
exposure to such risks. The sensitivity of earnings and cash flows to
variability in currency exchange rates is assessed by applying an appropriate
range of potential rate fluctuations to Mannatech's assets, obligations and
projected transactions denominated in foreign currency. Based upon its overall
currency rate exposure at June 30, 2001, Mannatech believes the actual impact of
future market changes could differ materially due to, among other things,
factors discussed in this report. Mannatech believes it cannot predict with any
certainty its future exposure to such currency exchange rate fluctuations or the
impact, if any, it may have on its future business, product pricing,
consolidated financial position, results of operations or cash flows; however,
Mannatech believes it closely monitors current fluctuations for exposure to such
market risk. Currently, the foreign currencies in which Mannatech has exposure
to foreign currency exchange rate risk include Australia, the United Kingdom and
Japan. The high and low currency exchange rates to the United States dollar, for
each of these countries, for the six months ended June 30, 2001 are as follows:


            Country/Currency                           High        Low
            ----------------                         --------    --------
            Australia/Dollar......................   $0.57220    $0.47730
            United Kingdom/British Pound..........   $1.51030    $1.36770
            Japan/Yen.............................   $0.00880    $0.00788

                                       17

     (b)  Reports on Form 8-K.

              On June 11, 2001, Mannatech filed a Form 8-K (File No. 000-24657)
          with the Securities and Exchange Commission in connection with the
          resignation of the Chairman of the Board and employee, Mr. Charles E.
          Fioretti. Mr. Fioretti continued to serve as a director on the Board
          of Directors. As a result of the resignation, Mannatech entered into a
          Separation Agreement and Full and Final Release (the "Separation
          Agreement") with Mr. Fioretti. Under the terms of the Separation
          Agreement, Mannatech agreed to pay Mr. Fioretti $1.2 million and buy
          an additional 50,000 shares of his common stock at a price of $1.45
          per share, which was the closing price of the stock on June 4, 2001.
          The previous Lock-Up Agreement dated August 8, 2000 with Mr. Fioretti
          will continue; however, the due date of the Renewal and Extension
          Promissory Note with Mr. Fioretti dated February 17, 1999 was modified
          to continue to accrued interest at 6.0%, with the remaining principal
          of $127,121.47 plus accrued interest extended to the earlier of (i)
          February 17, 2011 or (ii) thirteen days after the date that
          Mr. Fioretti no longer owns at least 100,000 shares of Mannatech's
          common stock.

               On June 26, 2001, Mannatech also filed a Form 8-K (File No.
          000-24657) with the Securities and Exchange Commission in connection
          with the resignation of the Executive Vice President of International
          Finance, Mr. Patrick D. Cobb. As a result of the resignation,
          Mannatech entered into a Separation Agreement and General Release (the
          "Separation Agreement") with Mr. Cobb. Under the terms of the
          Separation Agreement, Mannatech agreed to pay Mr. Cobb $900,000,
          transfer title of his leased automobile and grant Mr. Cobb a total of
          60,000 non-qualified stock options, which are exercisable through June
          30, 2011 at prices ranging from $2.25 per share to $4.00 per share.
