     Basic earnings per share were computed by dividing net income by the
weighted average number of common shares outstanding during each period. Diluted
earnings per share were computed by dividing net income by the weighted average
common shares outstanding after consideration of the dilutive effect of stock
options outstanding during each period.

Note 4: BUSINESS SEGMENT INFORMATION

     The Company operates in two major industry segments: minerals and
environmental. The Company also operates a transportation business. The minerals
segment mines, processes and distributes clays and products with similar
applications to various industrial and consumer markets. The environmental
segment processes and distributes clays and products with similar applications
for use as a moisture barrier in commercial construction, landfill liners and in
a variety of other industrial and commercial applications. The transportation
segment includes a long-haul trucking business and a freight brokerage business,
which provide services to both the Company's plants and outside customers.

     The Company identifies segments based on management responsibility and the
nature of the business activities of each component of the Company. Intersegment
sales are insignificant, other than intersegment shipping, which is disclosed in
the following table. The Company measures segment profit based on operating
profit. Operating profit is defined as sales less cost of sales and general,
selling and administrative expenses related to a segment's operations. The costs
deducted to arrive at operating profit do not include interest or income taxes.

     Segment assets are those assets used in the Company's operations in that
segment. Corporate assets include cash and cash equivalents, corporate leasehold
improvements, the nanocomposite plant investment and other miscellaneous
equipment.

Note 5: DERIVATIVES

     From time to time, the Company uses financial derivatives, principally
swaps, forward contracts and options, in its management of foreign currency and
interest rate exposures. These contracts hedge transactions and balances for
periods consistent with committed exposures.

     The Company uses variable rate credit facilities to finance its operations.
These debt obligations expose the Company to variability in interest payments
due to changes in interest rates. If interest rates increase, interest expense
increases. Conversely, if interest rates decrease, interest expense also
decreases. Through June 15, 2001, the Company was a party to an interest rate
swap agreement with a bank in the notional amount of $15 million. The agreement
gave the bank an option to extend the term. The interest rate swap agreement
changed the variable rate cash flow exposure on a portion of the Company's
borrowings under its committed credit facilities to fixed rate cash flows.

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                   (Continued)

     The agreement called for the Company to make fixed rate payments and to
receive variable rate cash flows based on the notional amount. This means the
Company received funds if the variable rate (LIBOR) increased above the fixed
rate, and paid the other party if LIBOR decreased below the fixed rate during
the term of the agreement. Interest rate differentials were paid or received on
a quarterly basis.

     Effective January 1, 2001, the Company adopted Statement of Financial
Accounting Standards (SFAS) No. 133, Accounting for Derivative Instruments and
for Hedging Activities, and SFAS No. 138, Accounting for Certain Derivative
Instruments and Certain Hedging Activities. The Company concluded that SFAS No.
133 required the change in value of this agreement to be recognized in its
operating results in the period of change. Accordingly, the Company recognized
the fair value of the swap and the option as of January 1, 2001 by recording the
cumulative effect of a change in accounting principle in the amount of $182 (net
of the related income tax benefit of $115) in the accompanying condensed
consolidated statements of operations. The change in the fair value of the swap
and option during the period through June 30, 2001 of $316 has been reflected in
operating results for the period.

Note 6: ACQUISITIONS

     On April 30, 2002, the Company acquired all of the outstanding stock of
Colin Stewart Minchem, Ltd. (CSM), a specialty minerals and chemical company
located in the United Kingdom, in exchange for cash. The aggregate purchase
price was $15,164. CSM supplies intermediate products, industrial minerals,
inorganic chemicals, and additives to customers operating in the laundry
detergent, packaging, oil exploration and water treatment markets. The
acquisition of CSM provides an additional platform for the Company to expand its
global operations and presence. The results of CSM's operations have been
included in the condensed consolidated financial statements from the acquisition
date.

     The following tables summarize the estimated fair values of the assets
acquired and liabilities assumed at the date of the acquisition and unaudited
pro forma results of operations as if the acquisition of CSM had occurred on
January 1, 2001. The unaudited pro forma information is not necessarily
indicative of the combined results that would have occurred had the acquisition
taken place at the beginning of the periods presented, nor is it necessarily
indicative of future results.

Note 7: DISCONTINUED OPERATIONS

     In 2000 the Company announced its intention to close its U.K. cat litter
business. Certain assets used in the business were sold to various outside
parties for cash proceeds of $720. The closure was completed in 2001. In the
fourth quarter of 2001, the Company announced the sale of its U.K. Metalcasting
operations. The U.K. cat litter and Metalcasting businesses were both components
of the Company's minerals segment.

     The consolidated financial statements have been reclassified to report
separately the net assets and operating results of the U.K. metalcasting and cat
litter business for all periods presented.

Summary operating results for 2001 were as follows:

Item 2: AMCOL INTERNATIONAL CORPORATION AND SUBSIDIARIES MANAGEMENT'S DISCUSSION
        AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

     The following is management's discussion and analysis of certain
significant factors which have affected the Company's financial position and
operating results during the periods included in the accompanying condensed
consolidated financial statements.

          Three Months Ended June 30, 2002 vs. 2001

     Net sales for the three month period were $78.5 million, which represented
an increase of $8.9 million, or 12.7% from 2001 levels. Mineral segment revenues
accounted for $8.7 million of the increase. As previously reported, the Company
acquired Colin Stewart Minchem Limited (CSM), a U.K.-based specialty minerals
company, effective from May 1, 2002. Revenues from CSM accounted for 53% of the
increase in sales from the 2001 period. Further discussion on sales is included
in the segment analysis which follows.

     Gross profit increased by $2.6 million, or 15.5%, to $19.3 million in the
second quarter of 2002. Increased revenues, as reported above, from the minerals
business units resulted in $1.4 million of gross profit improvement. Improved
production costs from the domestic operations of the Company's environmental
segment accounted for the remaining increase in gross profit from the prior year
period. Gross margin for the period was 24.5% compared to 24.0% in the previous
year's quarter.

     General, selling and administrative expenses increased by $1.3 million for
the second quarter of 2002 to $13.1 million. Overheads associated with the CSM
business contributed approximately 40% of the increase. Approximately 50% of the
increase in expenses was attributed to the environmental segment.

     Operating profit for the period was $6.2 million which was an increase of
$1.3 million, or approximately 26%, from the second quarter of 2002. The
increase followed the improvement in sales and gross profit.

     Investment income of $0.4 million in the second quarter of 2001 was
attributed to the temporary investment of the remaining proceeds from the sale
of the absorbent polymers segment which was sold in June 2000. The Company
utilized these proceeds to reduce its long-term debt in September of 2001.
Consequently, interest expense in the second quarter of 2002 declined by $0.7
million, or 83%, from the prior year quarter to $0.1 million.

     Income from joint ventures was $0.2 million in the current year period
compared with $0.1 million in last year's second quarter. The increase was
attributed to improved earnings recorded from an investment in an Indian
minerals company. The Company owns approximately 20% of the shares in this
company.

     Net income for the second quarter was $4.1 million compared with $3.0
million in the prior year period. The increase was primarily attributed to
higher operating profit and lower net interest expense in the current year
period.

------------------------------------------------------------------------------

     Effective April 30, 2002, the Company acquired a U.K. specialty minerals
business, Colin Stewart Minchem (CSM). The segment includes two months of
operating results for CSM in the second quarter of 2002. A pro forma
presentation of the operating results of the Company assuming the CSM
acquisition had been completed on January 1, 2001 is included in Note 6 to the
condensed consolidated financial statements included with this filing.

     Approximately 53% of the increase in sales for the second quarter of 2002
was attributed to CSM. Higher revenues from the metalcasting and export business
units contributed an increase of 16% and 12%, respectively, of the improvement
in sales.

     The increase in gross profit primarily followed the improvement in sales.
Gross margin declined, however, by 60 basis points primarily due to lower gross
profits generated from the pet products business.

     General, selling and administrative expenses increased primarily due to
CSM, increased information technology costs and increased research and market
development costs associated with the segment's health and beauty solutions
business.

     Net sales were relatively the same as the prior year period. Sales from the
segment's European business units were $1.1 million higher than the 2001
quarter, however, this was largely offset by lower sales in the U.S. and Asia.

     Gross margin improved by 400 basis points from the prior year period. Lower
unit production costs at the segment's domestic operations largely contributed
to the gross profit and margin improvement. The lower unit production costs were
the result of favorable raw material pricing and higher production volumes.

     General, selling and administrative expenses increased due to higher
compensation and benefit expenses, allocated information technology costs,
marketing and promotion costs, and research and development spending.

     Net sales declined due to lower customer shipments. Increased general,

     Intersegment shipping sales and costs are related to billings from the
transportation segment to the domestic minerals and environmental segments for
services. These services are invoiced to the minerals and environmental segments
at arms-length rates and those costs are subsequently charged to customers.
Intersegment sales and costs reported above reflect the elimination of these
transactions.

     Approximately 60% of the decline in corporate administrative expenses in
the current year period was associated with increased allocation of these costs
to the minerals, environmental and transportation segments. The remaining
decrease was attributed to lower personnel and legal costs.

     Nanocomposite business development expenses are comprised of production,
research and development and marketing costs. Expenses were relatively flat
compared to the prior year second quarter.

     Six Months Ended June 30, 2002 vs. 2001

     Net sales for the six month period ended June 30, 2002 increased to $135.9
million, or 1.4%, from the prior year period. Mineral segment sales increased by
$3.6 million while environmental and transportation segment revenues decreased
by $1.2 million and $0.6 million, respectively. CSM contributed $4.7 million in
sales to the mineral segment for the 2002 six month period. As previously
reported in this item, the acquisition of CSM was effective from April 30, 2002.

     Gross profit increased by $0.2 million, or less than 1%, for the six month
period. Lower gross profit from the pet products business largely offset
contributions from CSM. Gross margin was 23.5% for the six months ended June 30,
2002 compared to 23.7% for the prior year period.

     General, selling and administrative expenses increased by $1.5 million, or
6.0%, from the prior year period. Overhead expenses associated with CSM
accounted for approximately 35% of the increase. The Company also increased
research and development and marketing expenses during the six months ended June
30, 2002 compared to the prior year period.

     Operating profit declined by $1.3 million to $6.8 million for the six
months ended June 30, 2002 compared to the prior year period. The decline in
operating profit followed the increased general, selling and administrative
expenses incurred in the current year period.

     Investment income of $2.6 million recorded in the six months ended June 30,
2001 was attributed to the temporary investment of the remaining proceeds from
the sale of the absorbent polymers segment which was sold in June 2000. The
Company utilized these proceeds to reduce its long-term debt in September of
2001. Consequently, interest expense for the six months ended June 30, 2002
declined by $1.4 million, or 85%, from the prior year quarter to $0.2 million.

     In the first quarter of 2001 the Company recorded a loss of $316 thousand
due to the change in value of an interest rate swap contract. The loss was
recognized under the new requirements of Statement on Financial Accounting
Standards (SFAS) No. 133, Accounting for Derivative Instruments and for Hedging
Activities, and SFAS No. 138, Accounting for Certain Derivative Instruments and
Certain Hedging Activities. The Company also reported a loss on the cumulative
effect of a change in accounting principle of $182 thousand in the first quarter
of 2001 that was associated with implementation of this accounting
pronouncement.

     The effective income tax rate for the six months ended June 30, 2002 was
36% compared to 33% for the prior year period. The increased tax rate in the
current year was attributed to a greater portion of earnings generated in
countries with higher income tax rates.

     The loss from discontinued operations reported in the 2001 period reflects
the net loss incurred, after income taxes, in the UK metalcasting and cat litter
businesses. The UK metalcasting and cat litter businesses were disposed of in
the fourth quarter and first quarter of 2001, respectively.

     Income from joint ventures was $0.4 million for the six months ended June
30, 2002 compared with $0.2 million for the prior year period. The increase was
attributed to improved earnings recorded

                                       14

from an investment in an Indian minerals company. The Company owns approximately
20% of the shares in this Indian minerals company.

     Net income was $4.6 million for the six months ended June 30, 2002 compared
to $5.7 million for the prior year period. The decline in net income followed
lower operating profit reported in the current year period.

     CSM contributed sales of $4.7 million for the two months this business was
included in the segment's operating results. Excluding CSM, mineral segment
revenues declined by $1.1 million for the six months ended June 30, 2002. The
segment recorded lower sales in its oil drilling, export and pet products
businesses which totaled approximately $3.0 million. Sales from the segment's
metalcasting and Asian business units increased by a total of approximately $2.0
million from the prior year period.

     Gross profit, after excluding CSM, declined by approximately $1.3 million
from the prior year period. Higher production costs associated with the pet
products business were the primary cause for the lower gross profit in the
current year period.

     General, selling and administrative expenses increased primarily from the
inclusion of overhead associated with CSM. In addition, the segment incurred
higher research and development and marketing costs in its health and beauty
solutions business in the current year period.

--------------------------------------------------------------------------------

     The decline in sales was primarily attributed to lower volume levels in the
segment's U.S. drilling products and building materials business units.

     Gross profit remained relatively flat compared to the prior year period.
Improved unit production costs at the segment's U.S. production operations
offset the decline associated with lower sales.

     General, selling and administrative expenses increased due to higher
compensation and benefit expenses, allocated information technology costs,
marketing and promotion costs, and research and development spending.

     Intersegment shipping sales and costs are related to billings from the
transportation segment to the domestic minerals and environmental segments for
services. These services are invoiced to the minerals and environmental segments
at arms-length rates and those costs are subsequently charged to customers.
Intersegment sales and costs reported above reflect the elimination of these
transactions.

     Approximately 60% of the decline in corporate administrative expenses in
the current year period were associated with increased allocation of these costs
to the minerals, environmental and transportation segments. The remaining
decrease was attributed to lower personnel and legal costs.

     Nanocomposite business development expenses are comprised of production,
research and development and marketing costs. The decline in expenses is
associated with a restructuring of the business that was implemented in the
second quarter of 2001.

Liquidity and Capital Resources

     Working capital was $77.5 million as of June 30, 2002 compared to $70.1
million at December 31, 2001. The current ratio was 3.15-to-1 as of June 30,
2002 compared to 3.26-to-1 at December 31, 2001.

     For the six months ended June 30, 2002, cash flow from operating activities
was $6.0 million compared to $8.2 million for the prior year period. Lower net
income, a large increase in accounts receivable in the minerals business, and
the addition of working capital from CSM contributed to lower operating cash
flows in the six month period. The increase in accounts receivable was
attributed to large export shipments from the U.S. which were completed at the
end of the second quarter.

     The Company invested $7.3 million in capital expenditures in the current
year period compared to $4.5 million in the prior year period. A total of $16.8
million, including transaction costs, was utilized for acquisition of CSM and
the net assets of FNG Industries. Note 6 of the condensed consolidated financial
statements presents further information related to the CSM acquisition.

     A total of 654 thousand shares of the Company's common stock were
repurchased at an aggregate value of $4.0 million under the plan authorized by
the Company's board of directors in February 2001 and May 2002. Approximately
$8.2 million remains in the stock repurchase authorization as of June 30, 2002.
Dividends paid in the six month period were $1.0 million. The Company received
approximately $1.1 million from employees, directors and officers upon exercise
of stock options granted under incentive and non-qualified plans.

     Outstanding debt as of June 30, 2002 was $35.1 million which was an
increase of $21.9 million from December 31, 2001. Acquisitions accounted for a
majority of the increase in long-term debt in the six month period. Cash totaled
$7.7 million compared to $10.3 million at December 31, 2001. Long-term debt
represented 20% of total capitalization as of June 30, 2002 compared to 9% as of
December 31, 2001.

     The Company has a revolving credit facility of $125 million with financial
institutions that matures in October 2003. As of June 30, 2002 the Company had
approximately $97 million in unused, committed credit lines. The credit
facilities combined with funds generated from operations are

                                       17

expected to be adequate to fund capital expenditures and other investments
approved by the board of directors at this time.

New Accounting Pronouncements

     In July 2001, Statement of Financial Accounting Standards ("SFAS") No. 142,
Goodwill and Intangible Assets, was issued. SFAS No. 142 applies to all goodwill
and identified intangible assets acquired in a business combination. Under the
new standard, all goodwill, including that acquired before initial application
of the standard, will no longer be amortized, but should be tested for
impairment at least annually. Identified intangible assets will continue to be
amortized over their estimated useful lives and reviewed for impairment in
accordance with SFAS No. 144. Within six months of initial application of the
new standard, a transitional impairment test must be performed on all goodwill.
Any impairment loss recognized as a result of the transitional impairment test
will be reported as a change in accounting principle. In addition to the
transitional impairment test, the required annual impairment test must also be
performed in the year of adoption of SFAS No. 142. SFAS No. 142 is effective for
fiscal years beginning after December 15, 2001, and must be adopted as of the
beginning of a fiscal year. The Company adopted SFAS No. 142 effective January
1, 2002. The adoption of SFAS No. 142 had no impact on the financial statements.

     In June 2001, the FASB issued SFAS No. 143, "Accounting for Asset
Retirement Obligations" ("SFAS 143") which addresses financial accounting and
reporting for legal obligations associated with the retirement of tangible
long-lived assets and the related asset retirement costs. SFAS 143 requires that
the fair value of a liability for an asset retirement obligation be recognized
in the period in which it is incurred if a reasonable estimate of fair value can
be made. The fair value of the liability is added to the carrying amount of the
associated asset and this additional carrying amount is depreciated over the
life of the asset. Subsequent to the initial measurement of the asset retirement
obligation, the obligation is adjusted at the end of each period to reflect the
passage of time and changes in the estimated future cash flows underlying the
obligation. The Company is required to adopt SFAS No. 143 on January 1, 2003.
Management is currently evaluating the impact of the adoption of SFAS 143 on the
Company's consolidated financial statements.
