Note 1:     SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Company Operations

        Amcol International Corporation (the Company) operates in two principal
areas of activity: minerals and environmental. The Company also operates a
transportation business which includes delivery of its own products. For the
quarter ended March 31, 2005, the Company's revenues were derived 60% from
minerals, 35% from environmental, and 9% from transportation operations, all
reduced by 4% from the elimination of intersegment shipping revenues. For the
quarter ended March 31, 2004, the Company's revenues were derived 62% from
minerals, 32% from environmental, and 9% from transportation operations, all
reduced by 3% from the elimination of intersegment shipping revenues. Further
descriptions of the Company's products, it principal markets and the relative
significance of its operations are included in Note 5, "Business Segment
Information."

Basis of Presentation

        The financial information included herein has been prepared by
management and, other than the condensed consolidated balance sheet as of
December 31, 2004, is unaudited. The condensed consolidated balance sheet as of
December 31, 2004 has been derived from, but does not include all of the
disclosures contained in, the audited consolidated financial statements for the
year ended December 31, 2004. The information furnished herein includes all
adjustments that are, in the opinion of management, necessary for a fair
statement of the results of operations and cash flows for the interim periods
ended March 31, 2005 and 2004, and the financial position of the Company as of
March 31, 2005, and all such adjustments are of a normal recurring nature.
Management recommends that the accompanying condensed consolidated financial
information be read in conjunction with the consolidated financial statements
and related notes included in the Company's 2004 Annual Report on Form 10-K, as
amended.

        The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect the reported amounts of
assets and liabilities, disclosure of contingent liabilities at the date of the
financial statements, and the reported amounts of revenues and expenses during
the reporting period. Actual results may differ from those estimates.

        The results of operations for interim periods are not necessarily
indicative of the results to be expected for the full years.

Reclassifications

                                        8
<PAGE>

        Certain items in the condensed consolidated financial statements
contained herein and notes thereto have been reclassified to conform with the
consolidated financial statement presentation followed by the Company when it
prepared the consolidated financial statements included in its annual report on
Form 10-K, as amended, for the year ended December 31, 2004; these
reclassifications relate to commissions, intangible assets, reclamation
liabilities, and income taxes payable.

        In addition, net sales in periods prior to the quarter ended March 31,
2005 were reported net of certain deductions relating to product liability,
warranty and royalty expenses. Effective for the quarter ended March 31, 2005,
these deductions are included in general, selling, and administrative expenses.
Thus, for all periods prior to the quarter ended March 31, 2005 presented
herein, these deductions have been reclassified to conform to the current year
presentation. This reclassification did not impact net income or earnings per
share.

New Accounting Standards

        In 2003, the Company adopted FASB Statement No. 143, Accounting for
Asset Retirement Obligations, which addresses financial accounting and reporting
for legal obligations associated with the retirement of tangible along-lived
assets and the related asset retirement costs. In March 2005, the FASB issued
FASB Interpretation No. 47, Accounting for Conditional Asset Retirement
Obligations, an interpretation of FASB Statement No. 143 ("FIN 47"). FIN 47
clarifies both the definition of the term "conditional asset retirement
obligation" as that term is used in FASB Statement No. 143 and when an entity
would have sufficient information to reasonably estimate the fair value of an
asset retirement obligation. The Company's adoption of FIN 47 in March 2005 did
not have a material impact on the Company's condensed consolidated financial
statements.

Note 3:     LAND RECLAMATION

        The Company mines various minerals using a surface mining process that
requires the removal of overburden. Under various governmental regulations, the
Company is obligated to restore the land comprising each mining site to its
original condition at the completion of mining activity. The obligation is
adjusted to reflect the passage of time and changes in estimated future cash
outflows. A reconciliation of the activity within the Company's reclamation
obligation from December 31, 2004 to March 31, 2005 is as follows:

Note 4:     EARNINGS PER SHARE

        Basic earnings per share was computed by dividing net income by the
weighted average number of common shares outstanding during each period. Diluted
earnings per share was 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. For the quarter ended March 31, 2005,
the exercise price of all the outstanding stock options was below the average
market price and therefore the impact of these options was included in the
computation of diluted earnings per share.

Note 5:     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 both to 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 performance 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 6:     STOCK OPTION PLANS

        Prior to 2003, the Company accounted for its fixed plan stock options
under the recognition and measurement provisions of Accounting Principles Board
Opinion No. 25, Accounting for Stock Issued to Employees, and related
Interpretations. No stock-based employee compensation cost was reflected in net
income prior to 2003, as all options granted under those plans had an exercise
price equal to the market

value of the underlying common stock on the date of grant. Effective January 1,
2003, the Company adopted the fair value recognition provisions of SFAS No. 123,
Accounting for Stock-Based Compensation, and has elected to apply those
provisions prospectively, in accordance with SFAS No. 148, Accounting for
Stock-Based Compensation-Transition and Disclosure, an Amendment of FASB
Statement No. 123,, to all employee awards granted, modified, or settled after
January 1, 2003. Beginning in 2003, awards under the Company's plans vest over
three years. Therefore, the cost related to stock-based employee compensation
included in the determination of net income for 2004 and 2005 is less than that
which would have been recognized if the fair value based method had been applied
to all awards since the original effective date of Statement No. 123.

        Results for prior years have not been adjusted to reflect the use of the
fair value based method of accounting for employee awards. The following table
illustrates the effect on net income and earnings per share if the fair value

EMPLOYER CONTRIBUTIONS

        The Company previously disclosed in its financial statements for the
year ended December 31, 2004, that it expected to contribute $862 to its pension
plan in 2005. As of March 31, 2005, that full contribution has been made.

Note 8:     TAXES

        In October 2004, the American Jobs Creation Act (the "Act") was enacted
which allowed for a temporary 85% dividends received deduction on certain
foreign earnings repatriated into the U.S. The portion of the dividend that
qualifies for the 85% deduction is that amount which exceeds an average of past
years' foreign dividends. Additionally, certain criteria must be met when the
funds are repatriated and may ultimately qualify for an effective tax rate as
low as 5.25%.

        The Company is in process of evaluating whether it will repatriate
foreign earnings under the Act. The range of amounts that are reasonably under
consideration for repatriation are from $0 to $30.7 million. The Company will
evaluate the merits of repatriating foreign earnings in 2005 and report the tax
impact, if any, of an envisioned repatriation upon the finalization of a
repatriation plan. The Company has not recognized any income tax effect relating
to the Act as we are currently not in a position to reasonably estimate the tax
impact of any repatriation.

        In the three month period ending March 31, 2005, the Company decreased
its provision for taxes owed by $574 largely as a result of changes to estimated
depletion deductions.

Note 9:     ACQUISITIONS

        The Company did not make any acquisitions in the three months ended
March 31, 2005. As of December 31, 2004, the Company provided for $1,632 of
payments to be made to former owners of acquired businesses because the
operating performance of the acquired businesses met profit targets included in
earn-out provisions of the related purchase agreements. During the three months
ended March 31, 2005, those amounts were paid.

Note 10:    SUBSEQUENT EVENT

        In April 2005, the Company sold one of its manufacturing facilities for
$808 of cash proceeds, resulting in a pre-tax gain of $627 on the sale of
assets. This transaction is not reflected in the financial results for the three
month period ended March 31, 2005, but will be reflected in the financial
results reported for the second quarter of 2005.

                       CONDITION AND RESULTS OF OPERATIONS

FORWARD-LOOKING STATEMENTS

From time to time, certain statements we make, including statements in this
Management's Discussion and Analysis of Financial Condition and Results of
Operation section, constitute "forward-looking statements" made in reliance upon
the safe harbor contained in Section 21E of the Securities Exchange Act of 1934,
as amended. Such forward-looking statements include statements relating to our
Company or our operations that are preceded by terms such as "expects,"
"believes," "anticipates," "intends" and similar expressions, and statements
relating to anticipated growth and levels of capital expenditures. Such
forward-looking statements are not guarantees of future performance and involve
risks and uncertainties. Our actual results, performance or achievements could
differ materially from the results, performance or achievements expressed in, or
implied by, these forward-looking statements as a result of various factors,
including without limitation the following: actual performance in our various
markets; conditions in the metalcasting and construction industries; operating
costs; competition; currency exchange rates and devaluations; delays in
development, production and marketing of new products; and other factors set
forth from time to time in our reports filed with the Securities and Exchange
Commission.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

The discussion and analysis of our financial condition and results of operations
are based upon our condensed consolidated financial statements prepared in
accordance with accounting principles generally accepted in the United States.
We evaluate the accounting policies and estimates used to prepare the financial
statements on an ongoing basis. We consider the accounting policies used in
preparing our financial statements to be critical accounting policies when they
are both important to the portrayal of our financial condition and results of
operation, and require us to make estimates, complex judgments and assumptions,
including with respect to events which are inherently uncertain. As a result,
actual results could differ from these estimates. For more information on our
critical accounting policies, one should also read our Annual Report on Form
10-K, as amended, for the year ended December 31, 2004.

ANALYSIS OF RESULTS OF OPERATIONS

Following is a discussion and analysis that describes certain factors that have
affected, and may continue to affect, our financial position and operating
results. This discussion should be read with the accompanying condensed
consolidated financial statements. In addition, as discussed in Note 1 of the
Notes to Condensed Consolidated Financial Statements in Item 1, the Company has
reclassified certain financial data as of and for the three month period ended
March 31, 2005. The following discussion and analysis of results of operations
and financial condition are based upon such reclassified financial data.

THREE MONTHS ENDED MARCH 31, 2005 VS. MARCH 31, 2004:

RESULTS OF OPERATIONS (IN MILLIONS):

NET SALES:

                           2005            2004           % Change
                         --------        --------         --------
                         $  122.1        $  104.2               17%

        Favorable foreign currency changes accounted for approximately 9% of the
$17.9 million increase in net sales over the 2004 period. On an operating
segment basis, minerals accounted for approximately 51% of the increase in net
sales while environmental contributed approximately 48% of the growth. Our
transportation segment, after factoring out the impact of intersegment revenues,
accounted for approximately 1% of the sales growth over the first quarter of
2004.

GROSS PROFIT:

                           2005            2004           % Change
                         --------        --------         --------
                         $   29.7        $   26.7               11%
          Margin             24.3%           25.7%             N/A

        Gross profit improved in the first quarter of 2005 in conjunction with
the increase in net sales. Gross margin declined by 140 basis points due to
relatively lower gross profit earned from the minerals and environmental
segments. Higher transportation, raw materials and energy-related costs were the
primary causes for the decline in gross margins in both segments.

GENERAL, SELLING &
ADMINISTRATION EXPENSES:

                           2005            2004           % Change
                         --------        --------         --------
                         $   21.5        $   19.5               10%

        Higher corporate segment expenses accounted for approximately 82% of the
increase over the first quarter of 2004. Within the corporate segment, higher
audit and Sarbanes-Oxley compliance costs represented the largest component of
the increased corporate segment expenses. Research and development expenses were
approximately $1.7 million in the first quarter of 2005 compared with $1.3
million in last year's period.

OPERATING PROFIT:

                           2005            2004           % Change
                         --------        --------         --------
                         $    8.2        $    7.2               14%
          Margin              6.7%            7.0%             N/A

        Favorable foreign currency exchange rates accounted for approximately 9%
of the increase in operating profit over the 2004 first quarter, or 1.3
percentage points of growth. The 20 basis point decline in operating margin was
attributed to the decrease in gross margin described above.

INTEREST EXPENSE, NET:

                           2005            2004           % Change
                         --------        --------         --------
                         $    0.4        $    0.1              357%

        Interest expense in the first quarter of 2005 increased primarily due to
higher average long-term debt compared with the prior year period. The increase
in long-term debt was attributed to acquisitions completed in 2004 and an
increase in working capital funding.

INCOME TAXES:

                           2005            2004           % Change
                         --------        --------         --------
                         $    1.5        $    2.3              (35)%
          Effective tax
           rate              19.1%           31.5%             N/A

        The effective tax rate was favorably impacted by lower foreign tax rates
in comparison with the 2004 period. Additionally, the 2005 period was positively
impacted by a change in estimate of 2004 income taxes payable, which was
approximately $574,000. After factoring out this adjustment, the effective tax
rate would have been 26.5%, and management believes this rate is indicative of
the expected rate for the fiscal year ending December 31, 2005.

INCOME FROM JOINT  VENTURES AND MINORITY INTERESTS:

                           2005            2004           % Change
                         --------        --------         --------
                         $    0.7        $    0.1              351%

        The primary reason for the increase in income recorded in this category
was improved profitability of two investments in Indian entities: one comprised
of a 20% interest in a bentonite company and the other being a 50% interest in a
joint venture that manufactures and distributes treated clays used for
clarifying edible oils. We also recorded income from our 50% interest in a
Japanese bentonite company. In the third quarter of 2004, we increased our
interest from 19% in this venture and, therefore, began to account for it under
the equity method instead of recording income when dividends were received as
required under the cost method of accounting.

NET INCOME:

                           2005            2004           % Change
                         --------        --------         --------
                         $    7.0        $    5.1               37%
          Margin              5.7%            4.9%             N/A

         Net margin in the 2005 period increased primarily due to the increase
in operating profit, the lower effective tax rate and the improvement in income
from joint ventures and minority interests.

DILUTED EARNINGS PER  SHARE:

                           2005            2004           % Change
                         --------        --------         --------
                         $   0.23        $   0.16               44%

        Growth in base-business sales and operating profit contributed
approximately $0.02 per share of the increase over the first quarter of 2004. A
lower effective income tax rate accounted for $0.03 per share of the increase
over the prior-year period. Income from joint ventures and minority interests
contributed approximately $0.02 of the increase. Weighted average common and
common equivalent shares outstanding decreased by less than 1% over the 2004
quarter.

        SEGMENT ANALYSIS:

        Following is a review of operating results for each of our four
reporting segments:

</TABLE>

        Favorable foreign currency translation rates accounted for approximately
7.0% of the sales growth over the 2004 period. Domestic metalcasting sales were
positively impacted by higher demand and price increases that were implemented
to offset rising transportation, raw materials and energy-related costs. The
metalcasting markets in the Asia/Pacific region also continued to benefit from
strong demand from automotive and transportation equipment component
manufacturers. Pet products sales increased due to higher volume in comparison
with the prior-year period. Specialty minerals revenues were flat.

        Gross profit rose in conjunction with the increase in sales albeit at a
slower rate. Gross margin declined by 170 basis points in comparison with the
prior-year period due to the rising costs of the metalcasting and pet products
business mentioned above.

        General, selling and administrative costs increased modestly primarily
due to higher expenses associated with the health and beauty business.

        Operating profit improved due to the increase in sales and gross profit.
Operating margin decreased by 90 basis points due to the decline in gross
margin. The domestic metalcasting and pet products businesses continue to see
rising manufacturing costs. Our ability to obtain price increases is necessary
to restore gross margin to historical levels.

</TABLE>

        Favorable currency exchange rates accounted for approximately 11% of the
increase in sales. Strong demand in the domestic lining technologies, building
materials and water treatment businesses led to the increase in sales over the
2004 first quarter. Growth in lining technologies product demand in Europe and
Asia also contributed to the increase. The water treatment increase arose from
higher demand for products and services from our oilfield services businesses.
Price increases had a minimal impact on revenue growth in the quarter.

<PAGE>

        Gross profit grew in conjunction with the increase in net sales;
however, gross margin declined by 290 basis points from the first quarter of
2004. Gross margins on lining technologies sales declined due to the mix of
product sales to lower profit items. This was especially evident in Europe.
Also, higher transportation, raw materials and energy-related costs negatively
impacted manufacturing costs in comparison with the prior-year period.

        General, selling and administrative expenses were flat due to spending
controls implemented throughout the segment.

        Operating profit improved due to the increase in sales and gross profit
and the flat general, selling and administrative expenses. Consequently,
operating margin improved by 300 basis points. The outlook for the segment
appears favorable as it enters the period in which the lining technologies and
building materials businesses generate most of their revenue and profits. Water
treatment prospects continue to appear positive due to the demand for oilfield
services and products.

        Intersegment shipping revenues 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.

        Corporate general, selling and administrative expenses increased
primarily due to higher audit and compliance costs related to the Sarbanes-Oxley
Act of 2002. Additionally, we incurred higher

                                       20
<PAGE>

corporate development costs related to new business ventures in the first
quarter of 2005. We expect corporate segment expenses to exceed prior-year
spending due to higher regulatory compliance costs.

        Net nanocomposite operating expenses were relatively flat in comparison
with the 2004 first quarter. This business has alliance agreements with
Mitsubishi Gas Chemical Company and Poly One Corporation that focus on
developing certain markets for nanocomposites. We continue to see active
interest in our nanocomposite technologies through the market development
activities undertaken by our alliance partners.

Net cash provided by (used in) operating activities      $     2.7    $    (3.0)
Net cash provided by (used in) investing activities      $    (5.7)   $   (15.9)
Net cash provided by (used in) financing activities      $     5.7    $    15.4

        Cash flows provided by operating activities improved over the 2004
period as a result of higher net income and slower growth in working capital.
Historically, cash flows from operations have increased over the course of the
fiscal year and we anticipate this pattern to continue for the remainder of
2005.

        Cash flows used in investing activities decreased primarily due to
acquisitions completed in the first quarter of 2004. We acquired the shares of
Lafayette Well Testing, Inc. on January 7, 2004, and Linteco Geotechnische
Systeme GmbH on March 5, 2004. The aggregate purchase price for the two
companies was approximately $13.2 million. Capital expenditures to-date in 2005
totaled $5.2 million compared with $3.2 million in the prior-year period. We
anticipate capital expenditures to increase over the remainder of 2005 due to
investments in capacity expansion and productivity projects. Our investments in
Europe and Asia will focus on adding new production capacity to support growth
in lining technologies and metalcasting businesses, respectively. Our estimate
of 2005 capital expenditures is in the range of $22 million to $26 million.

        Cash flows provided by financing activities decreased due to debt
funding for acquisitions completed in the 2004 first quarter. We used our
revolving credit facility to finance the acquisitions. Additionally, we assumed
approximately $4.1 million of funded debt as part of the consideration for the
Linteco acquisition. Dividends paid to-date in 2005 increased to $2.7 million
from $2.0 million in the prior-year period. We did not purchase any shares of
our common stock in the first quarter of 2005. We did purchase 12,400 shares of
our common stock on the open market during the first quarter of 2004 for a total
value of $196,300, or an average price per share of $15.83. On May 13, 2004, the
board of directors authorized funds to repurchase up to $10 million of our
common stock on the open market over a two-year period if we believe such a use
of our cash will enhance shareholder value. The entire $10 million remains
available to repurchase common stock as of March 31, 2005.

        Working capital at March 31, 2005 increased from December 31, 2004,
primarily due to growth in inventories and accounts receivable. The growth in
inventories was due to stocking our Asian locations earlier than normal to
economize on shipping costs. Inventory values at March 31, 2005 also reflect the
higher cost of raw materials and transportation costs. The current ratio was
3.3-to-1 and 3.1-to-1 at March 31, 2005, and December 31, 2004, respectively.

        Intangible assets primarily represent goodwill associated with
acquisitions.

        Long-term debt increased to 16% of total capitalization at March 31,
2005, compared with 13% at December 31, 2004. The increase in debt levels was
principally attributed to funding working capital. We have a $100 million
revolving credit facility with a consortium of U.S. banks that matures on
October 31, 2006. At March 31, 2005, we had approximately $63 million of
borrowing capacity remaining from the credit facility. The credit facility
stipulates that we must comply with a number of financial covenants. We are in
compliance with those covenants at March 31, 2005.

        Other long-term obligations primarily represent liabilities associated
with our qualified and supplemental retirement plans and deferred income taxes.

        We believe future cash flows from operations combined with borrowing
capacity from our revolving credit facility will be adequate to fund capital
expenditures and other investments approved by the board of directors.

        Since the mid 1980's, the Company and/or its subsidiaries have been
named as one of a number of defendants in product liability lawsuits relating to
the minor free-silica content within the Company's bentonite products used in
the metalcasting industry. The plaintiffs in these lawsuits are primarily
employees of the Company's foundry customers. To date, the Company has not
incurred significant costs in defending these matters. The Company believes it
has adequate insurance coverage and does not believe the litigation will have a
material adverse impact on the financial condition, liquidity or results of the
operations of the Company.

ITEM 3:     QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

        There have been no material changes in the Company's market risk during
the three months ended March 31, 2005. See disclosures as of December 31, 2004
in the Company's Annual Report on Form 10-K, as amended, Item 7A.

                                       22
<PAGE>

ITEM 4:     CONTROLS AND PROCEDURES

        An evaluation has been performed under the supervision and with the
participation of our management, including the Chief Executive Officer and Chief
Financial Officer, of the effectiveness of the design and operation of our
disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e)
promulgated under the Securities Exchange Act of 1934) as of March 31, 2005.
Based upon that evaluation, the Chief Executive Officer and Chief Financial
Officer have concluded that, as a result of the material weakness in our
internal control over financial reporting discussed below and the fact that the
remedial efforts of the Company had not been completed as of March 31, 2005 as
discussed below, our disclosure controls and procedures were not effective as of
March 31, 2005 to ensure that information required to be disclosed in the
reports we file or submit under the Exchange Act are recorded, processed,
summarized and reported as and when required. Notwithstanding the foregoing,
management believes that the financial statements included within this report
fairly present in all material respects the financial position, results of
operations, and cash flows of the Company, in conformity with generally accepted
accounting principles in the United States, for the periods presented.

        The Securities and Exchange Commission, as directed by Section 404 of
the Sarbanes-Oxley Act of 2002, adopted rules requiring public companies to
include in their annual reports on Form 10-K an assessment by management of the
effectiveness of the Company's internal controls over financial reporting. As
described in the annual report on Form 10-K filed by the Company for the year
ended December 31, 2004, as amended, management identified a material weakness
in internal control over financial reporting relative to our accounting for
income taxes as of December 31, 2004. In particular, our design of internal
controls did not address the accounting considerations arising from the filing
of tax returns or the timing of recording of changes in accounting estimates
relating to income taxes of foreign subsidiaries. As a result of the foregoing,
we began implementing changes in our internal control over financial reporting
(as such term is defined in Rules 13a-15(f) and 15d-15(f) promulgated under the
Securities Exchange Act of 1934) during the fiscal quarter ended March 31, 2005
that materially affected, or are reasonably likely to materially affect, our
internal controls over financial reporting.

        Specifically, these changes include restructuring the responsibility for
accounting for income taxes, formalizing management's oversight relating to
accounting for income taxes by developing procedures to monitor significant
income tax events and the determination of appropriate accounting treatment for
certain deduction and credit positions taken in filing income tax returns, both
amended and original, and developing a program to provide increased training to
improve our accounting for income taxes. Our Tax Manager is now fully
responsible for the financial accounting for income taxes. In addition, the
Controller and Chief Financial Officer receive quarterly updates on tax matters,
including changes in tax positions that may have a material effect on the
financial statements and matters affecting income tax returns. The Controller
and Chief Financial Officer review these matters and document conclusions as to
the accounting treatment. Additionally, we are enhancing controls over financial
reporting of our foreign subsidiaries to assure the consolidated financial
statements are presented in accordance with U.S. generally accepted accounting
principles and changes in accounting estimates are recorded in the appropriate
reporting period. Last, the Chief Financial Officer will conduct an annual
assessment of the accounting staff's knowledge of U.S. generally accepted
accounting principles and provide additional training where necessary.

        Although remedial efforts were initiated in the first quarter of 2005,
the implementation of such changes had not been completed as of March 31, 2005.
Accordingly, management has determined that

                                       23
<PAGE>

the material weakness in the Company's internal control over financial reporting
relative to our accounting for income taxes as described in the annual report on
Form 10-K filed by the Company for the year ended December 31, 2004, as amended,
still existed as of March 31, 2005.
