     The accompanying unaudited condensed consolidated financial statements have been prepared by management in accordance with the rules and regulations of the United States Securities and Exchange Commission. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted. Therefore, these financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2002. In the opinion of management, all adjustments, consisting solely of normal recurring adjustments necessary for a fair presentation of the financial information for the periods indicated, have been included. The results for the three-month and nine-month periods ended September 28, 2003 are not necessarily indicative of the results that may be expected for the year ending December 31, 2003.

     Property, plant and equipment are recorded at cost. Significant improvements are capitalized, while maintenance and repair expenditures are charged to operations as incurred. The Company capitalizes interest cost as a component of construction in progress. In general, the straight-line method of depreciation is used for financial reporting purposes and accelerated methods are used for U.S. and certain foreign tax reporting purposes. The annual rates of depreciation are 3% - 6.67% for buildings, 6.67% - 12.5% for machinery and equipment, 8% - 12.5% for furniture and fixtures and 12.5% - 25% for computer equipment and software-related assets.

     Property, plant and equipment are amortized over their useful lives. Useful lives are based on management's estimates of the period that the assets can generate revenue, which does not necessarily coincide with the remaining term of a customer's contractual obligation to purchase products made using those assets. The Company's sales of PCC are predominantly pursuant to long-term contracts, initially ten years in length, with paper mills at which the Company operates satellite PCC plants. The terms of many of these agreements have been extended, often in connection with an expansion of the satellite PCC plant. The Company also continues to supply PCC at one location at which the PCC contract has expired. Failure of a PCC customer to renew an agreement or continue to purchase PCC from a Company facility could result in an impairment of assets charge at such facility.

     In the third quarter of 2002, the Company reduced the useful lives of satellite PCC plants at International Paper Company's ("IP") mills due to an increased risk that some or all of these PCC contracts would not be renewed. As a result of this change, the Company also reviewed the useful lives of the assets at its remaining satellite PCC facilities and other plants. During the first quarter of 2003, the Company revised the estimated useful lives of machinery and equipment pertaining to its natural stone mining and processing plants and chemical processing plants from 12.5 years (8%) to 15 years (6.67%) and reduced the useful lives of buildings at certain satellite PCC facilities from 25 years (4%) to 15 years (6.67%). The Company also reduced the estimated useful lives of certain software-related assets due to implementation of a new global enterprise resource planning system. During the second quarter of 2003, the Company reached an agreement with IP that extended eight PCC supply contracts and therefore extended the useful lives of the satellite PCC plants at those IP mills. The net effect of the changes in estimated useful lives, including the deceleration of depreciation at the IP plants, was an increase to diluted earnings per share of $0.04 in the third quarter of 2003 and $0.04 for the first nine months of 2003.

     Depletion of mineral reserves is determined on a unit-of-extraction basis for financial reporting purposes and on a percentage depletion basis for tax purposes.

     Mining costs associated with waste gravel and rock removal in excess of the expected average life of mine stripping ratio are deferred. These costs are charged to production on a unit-of-production basis when the ratio of waste to ore mined is less than the average life of mine stripping ratio.

     In December 2002, The FASB issued SFAS No. 148, "Accounting for Stock-Based Compensation - Transition and Disclosure, an amendment of SFAS No. 123." This statement amends SFAS No. 123, "Accounting for Stock-Based Compensation," to provide alternative methods of transition for a voluntary change to the fair value based method of accounting for stock-based employee compensation, and requires additional disclosures in interim and annual financial statements. The disclosure in interim periods requires pro forma net income and net income per share as if the Company adopted the fair value method of accounting for stock-based awards. The fair value of stock-based awards to employees was calculated using the Black-Scholes option-pricing model, modified for dividends. Pro forma net income and earnings per share reflecting compensation cost for the fair value of stock options were as follows:

     The following is a summary of long-term debt:

     On May 31, 2003, the Company acquired land and limestone ore reserves from the Cushenbury Mine Trust for approximately $17.5 million. Approximately $6.1 million was paid at the closing and $11.4 million was financed through an installment obligation. The average interest rate on this obligation is approximately 4.25%. The principal payments are as follows: 2004 - $0.8 million; 2005 - $0.9 million; 2006 - $0.9 million; 2007 - $0.9 million; 2008 - $6.5 million; 2013 - $1.4 million.

     Basic earnings per share are based upon the weighted average number of common shares outstanding during the period. Diluted earnings per share are based upon the weighted average number of common shares outstanding during the period assuming the issuance of common shares for all dilutive potential common shares outstanding. The following table sets forth the computation of basic and diluted earnings per share:

     Segment information for the three months and nine months ended September 28, 2003 and September 29, 2002 was as follows:

     Included in income from operations of the Specialty Minerals segment for the first quarter of 2003 was a charge for one-time termination benefits of $660,000. Included in income from operations of the Specialty Minerals segment for the first quarter of 2002 was a write-down of impaired assets of $750,000.

     The carrying amount of goodwill by reportable segment as of September 28, 2003 and December 31, 2002 was as follows:

     The Company accounts for goodwill and other intangible assets in accordance with Statement of Financial Accounting Standards (SFAS) No. 142, "Goodwill and Other Intangible Assets." Under SFAS No. 142, goodwill and other intangible assets with indefinite lives are no longer amortized, but instead are tested for impairment at least annually in accordance with the provisions of SFAS No. 142.

     The carrying amount of goodwill was $51.7 million and $51.3 million as of September 28, 2003 and December 31, 2002, respectively. The net change in goodwill since January 1, 2003 was primarily attributable to the effects of foreign exchange rates.

     Acquired intangible assets subject to amortization as of September 28, 2003 and December 31, 2002 were as follows:
