NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

Note 1.  Basis of Presentation

     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 U.S. 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, 2009.  In the opinion of management, all adjustments, consisting solely of normal recurring adjustments necessary for a fair presentation of the financial inf ormation for the periods indicated, have been included.  The results for the three-month and six-month periods ended July 4, 2010 are not necessarily indicative of the results that may be expected for the year ending December 31, 2010.

Note 2.  Summary of Significant Accounting Policies

     Use of Estimates

     The Company employs accounting policies that are in accordance with U.S. generally accepted accounting principles and require management to make estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reported period. Significant estimates include those related to revenue recognition, allowance for doubtful accounts, valuation of inventories, valuation of long-lived assets, goodwill and other intangible assets, pension plan assumptions, income tax, valuation allowances, and litigation and environmental liabilities. Actual results could differ from those estimates.

Note 3.  Earnings Per Share (EPS)

     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:

			Three Months Ended					Six Months Ended
Basic EPS (in millions, except per share data)				July 4, 2010		June 28, 2009			July 4, 2010		June 28, 2009

     Options to purchase 621,814 shares of common stock and 773,589 shares for the three month and six month periods ended July 4, 2010 and June 28, 2009, respectively, were not included in the computation of diluted earnings per share because they were anti-dilutive, as the exercise prices of the options were greater than the average market price of the common shares.  The weighted average diluted common shares outstanding for the three-month and six-month periods ended June 28, 2009 excludes stock options and restricted stock, as inclusion of these would be anti-dilutive. During the three-month and six-month periods ended June 28, 2009, approximately 9,000 and 11,000 common equivalent shares, respectively, were not included in the computation of diluted earnings per share.

Note 4.   Discontinued Operations

     In the third quarter of 2007, as a result of a change in management and deteriorating financial performance, the Company conducted an in-depth review of all of its operations and developed a new strategic focus. The Company initiated a plan to realign its business operations to improve profitability and increase shareholder value by exiting certain businesses and consolidating some product lines.  As a part of this restructuring, during the fourth quarter of 2007, the Company classified its Synsil operations and its plants at Mount Vernon, Indiana and Wellsville, Ohio as discontinued operations. These operations were part of the Company's Specialty Minerals segment.  During 2008, the Company sold its idle Synsil facilities in Chester, South Carolina, Woodville, Ohio and Cleburne, Texas and its facility in Wellsville, Ohio. In the fourth quarter of 2009, the Company sold its operations at Mt. Vernon, Indiana.

     The following table details selected financial information for the discontinued operations in the consolidated statements of operations. The amounts exclude general corporate overhead and interest expense which were previously allocated to the entities comprising discontinued operations.

Note 5.   Income Taxes

     As of July 4, 2010, the Company had approximately $8.0 million of total unrecognized income tax benefits. Included in this amount were a total of $5.7 million of unrecognized income tax benefits that if recognized would affect the Company’s effective tax rate. While it is expected that the amount of unrecognized tax benefits will change in the next 12 months, we do not expect the change to have a material impact on the results of operations or the financial position of the Company.

     The Company’s accounting policy is to recognize interest and penalties accrued relating to unrecognized income tax benefits as part of its provision for income taxes. The Company had reversals of approximately $0.5 million and $0.3 million during the second quarter and first half of 2010, respectively, and has an accrued balance of $2.1 million of interest and penalties accrued as of July 4, 2010.

     The Company operates in multiple taxing jurisdictions, both within and outside the U.S.  In certain situations, a taxing authority may challenge positions that the Company has adopted in its income tax filings. The Company, with a few exceptions (none of which are material), is no longer subject to U.S. federal, state, local, and international income tax examinations by tax authorities for years prior to 2003.

Note 6.   Inventories

     The following is a summary of inventories by major category:

(millions of dollars)		July 4, 2010		December 31, 2009

Packaging and supplies		18.8		19.2
Total inventories	$	81.7	$	82.5

Note 7.  Goodwill and Other Intangible Assets

     Goodwill and other intangible assets with indefinite lives are not amortized, but instead are tested for impairment, at least annually. The carrying amount of goodwill was $66.6 million, and $68.1 million as of July 4, 2010 and December 31, 2009, respectively.  The net change in goodwill since December 31, 2009 was attributable to the effect of foreign exchange.

MINERALS TECHNOLOGIES INC. AND SUBSIDIARY COMPANIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

     Acquired intangible assets subject to amortization as of July 4, 2010 and December 31, 2009 were as follows:

	July 4, 2010				December 31, 2009
(millions of dollars)		Gross Carrying Amount		Accumulated Amortization		Gross Carrying Amount		Accumulated Amortization
Patents and trademarks	$	6.2	$	3.3	$	6.2	$	3.1
Customer lists		2.7		1.2		2.7		1.1
	$	8.9	$	4.5	$	8.9	$	4.2

     The weighted average amortization period for acquired intangible assets subject to amortization is approximately 15 years.  Estimated amortization expense is $0.6 million for each of the next five years through 2014.

     Also included in other assets and deferred charges is an intangible asset of approximately $1.5 million which represents the non-current unamortized amount paid to a customer in connection with contract extensions at seven PCC satellite facilities.  The current portion of $1.0 million is included in prepaid expenses and other current assets.  Such amounts will be amortized as a reduction of sales over the remaining lives of the customer contracts.  Approximately $0.3 million was amortized in the second quarter of 2010.  Estimated amortization as a reduction of sales is as follows: remainder of 2010 - $0.4 million; 2011 - $0.7 million; 2012 - $0.5 million; 2013 - $0.4 million; 2014 - $0.4 million; with smaller reductions thereafter over the remaining lives of the cont racts.

Note 8.  Restructuring Costs

2007 Restructuring Program

    In the third quarter of 2007, as a result of a change in management and deteriorating financial performance, the Company conducted an in-depth review of all its operations and developed a new strategic focus. The Company initiated a plan to realign its business operations to improve profitability and increase shareholder value by exiting certain businesses and consolidating some product lines. As part of this program, the Company reduced its workforce by approximately 7 percent to better control operating expenses and improve efficiencies and recorded a pre-tax charge of $16.0 million for restructuring and other exit costs during the second half of 2007. This charge consisted of severance and other employee benefit costs of $13.5 million, contract termination costs of $1.8 million and other exit costs of $0.7 mi llion. Additional restructuring costs of $9.5 million were recorded in 2008 related to this program, including a pension settlement loss of approximately $6.8 million related to the distribution of benefits to terminated employees. The restructuring resulted in a total workforce reduction of approximately 250, which has been completed.

      A reconciliation of the restructuring liability for this program, as of July 4, 2010, is as follows:

(millions of dollars)	Balance as of  December 31, 2009		Additional Provisions		Cash Expenditures			Balance as of July 4, 2010
Severance and other employee benefits	$	0.1	$	--	$	(0.1	)	$	--
Contract termination costs		1.6		--		(0.3	)		1.3
	$	1.7	$	--	$	(0.4	)	$	1.3

      Approximately $0.1 million and $0.4 million in termination costs were paid in the second quarter and first six months of 2010, respectively.  The remaining restructuring liability of $1.3 million will be funded from operating cash flows and the program is expected to be completed in 2010.

2008 Restructuring Program

     In the fourth quarter of 2008 as a result of the worldwide economic downturn and the resulting impact on our sales and operating profits, the Company initiated an additional restructuring program by reducing its workforce by approximately 14% through a combination of permanent reductions and temporary layoffs. The Company recorded a charge of $3.9 million associated with this program.

Severance and other employee benefits	$	0.1	$	--		--	$	0.1

  The remaining liability of $0.1 million will be funded from operating cash flows and the program is expected to be completed in 2010.

2009 Restructuring Program

      In the second quarter of 2009, the Company initiated a program to improve efficiencies through the consolidation of manufacturing operations and reduction of costs.

     The restructuring program reduced the workforce by approximately 200 employees worldwide.  This reduction in force relates to plant consolidations as well as a streamlining of the corporate and divisional management structures to operate more efficiently.

     A reconciliation of the restructuring liability for this program, as of July 4, 2010, is as follows:

(millions of dollars)		Balance as of December 31, 2009		Additional Provisions			Cash Expenditures			Other			Balance as of July 4, 2010
Severance and other employee benefits	$	5.0	$	0.6		$	(1.9	)	$	(0.1	)	$	3.6

Other exit costs		0.1		(0.1	)		--			--			--
	$	5.5	$	0.1		$	(1.9	)	$	(0.1	)	$	3.6

     Approximately $0.4 and $1.9 in severance payments were paid in the second quarter and first six months of 2010. The remaining liability of $3.6 million will be funded from operating cash flows and the program is expected to be completed in the second half of 2010.

Other Restructuring

In the fourth quarter of 2009, the Company recorded restructuring charges for the announced closure of the paper mill at its Franklin, Va. satellite facility.

    A reconciliation of the restructuring liability for this closure, as of July 4, 2010, is as follows:

(millions of dollars)	Balance as of December 31, 2009		Additional Provisions			Cash Expenditures				Other				Balance as of July 4, 2010
Severance and other employee benefits	$	0.1	$	--	$		--		$		--		$	0.1
Contract termination costs		0.9		--			--				(0.9	)		0.0

Note 9.  Accounting for Impairment of Long-Lived Assets

     Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. In such instances, the Company estimates the undiscounted future cash flows (excluding interest) resulting from the use of the asset and its ultimate disposition.  If the sum of the undiscounted cash flows (excluding interest) is less than the carrying value, the Company recognizes an impairment loss, measured as the amount by which the carrying value exceeds the fair value of the asset.

     In the second quarter of 2009, the Company initiated a restructuring program to improve efficiencies through the consolidation of operations and rationalization of certain product lines, and through the reduction of costs. As part of this program, the Company consolidated its Old Bridge, New Jersey operation into Bryan, Ohio and Baton Rouge, Louisiana, in order to improve operational efficiencies and reduce logistics for key raw materials, which resulted in an impairment of assets charge of $4.3 million; rationalized its North American specialty shapes product line resulting in an impairment of assets charge of $1.5 million; rationalized some of its European operations resulting in an impairment of assets charge of $2.2 million; recorded further impairment charges of $10.0 million related to its Asian refr actory operations as a result of continued difficulties in market penetration as well as consolidated its Asian operations and actively seek a regional alliance to aid in marketing its high value products; recognized impairment charges for refractory application equipment in North America of $3.7 million and Europe of $3.3 million due to customer underutilized assets under depressed volume conditions; recorded an impairment charge of $6.5 million related to the Company's PCC facility in Millinocket, Maine.

As a result of this realignment, the Company recorded an impairment of assets charge of $37.5 million.  The following table reflects the major components of the impairment of assets charge along with the remaining carrying value of the impaired assets at the time of the impairment:

Impairment of assets:

(millions of dollars)	Second Quarter 2009		Remaining Carrying Value of Impaired Assets
Americas Refractories	$	9.5	$	0.3
European Refractories		11.5		0.8
Asian Refractories		10.0		11.6
North America Paper PCC		6.5		--
Total impairment	$	37.5	$	12.7

Included in the impairment of assets charge for Europe Refractories is a $6.0 million charge for certain intangible assets from the 2006 acquisition of a business in Turkey.

     The remaining carrying value of the impaired assets was determined by estimating marketplace participant views of the discounted cash flows of the asset groups, and in the case of tangible assets, by estimating the market value of the assets, which due to the specialized and limited use nature of our equipment, is primarily driven by the value of the real estate.  As the estimated discounted cash flows were determined to be negative under multiple scenarios, the highest and best use of the tangible asset groups was determined to be the sale of the underlying real estate. The fair value of the significant real estate holdings was based on independent appraisals.

The Company expected to realize, beginning in the third quarter of 2009, annualized pre-tax depreciation savings of approximately $5 million related to the write-down of fixed assets. The Company realized depreciation savings of $2.4 million in the first half of 2010.

Note 14.  Legal Proceedings

     Certain of the Company's subsidiaries are among numerous defendants in a number of cases seeking damages for exposure to silica or to asbestos containing materials.  The Company currently has 305 pending silica cases and 28 pending asbestos cases.  To date, 1,160 silica cases and 4 asbestos cases have been dismissed. Most of these claims do not provide adequate information to assess their merits, the likelihood that the Company will be found liable, or the magnitude of such liability, if any.  Additional claims of this nature may be made against the Company or its subsidiaries.  At this time management anticipates that the amount of the Company's liability, if any, and the cost of defending such claims, will not have a material effect on its financial position or res ults of operations.

     The Company has not settled any silica or asbestos lawsuits to date.  We are unable to state an amount or range of amounts claimed in any of the lawsuits because state court pleading practices do not require identifying the amount of the claimed damage.  The aggregate cost to the Company for the legal defense of these cases since inception was approximately $0.1 million, the majority of which has been reimbursed by Pfizer Inc pursuant to the terms of certain agreements entered into in connection with the Company's initial public offering in 1992.  Our experience has been that the Company is not liable to plaintiffs in any of these lawsuits and the Company does not expect to pay any settlements or jury verdicts in these lawsuits.

Environmental Matters

     On April 9, 2003, the Connecticut Department of Environmental Protection issued an administrative consent order relating to our Canaan, Connecticut, plant where both our Refractories segment and Specialty Minerals segment have operations. We agreed to the order, which includes provisions requiring investigation and remediation of contamination associated with historic use of polychlorinated biphenyls ("PCBs") at a portion of the site. The following is the present status of the remediation efforts:

• Building Decontamination. We have completed the investigation of building contamination and submitted a report characterizing the contamination. We are awaiting review and approval of this report by the regulators. Based on the results of this investigation, we believe that the contamination may be adequately addressed by means of encapsulation through painting of exposed surfaces, pursuant to the Environmental Protection Agency's ("EPA") regulations and have accrued such liabilities as discussed below. However, this conclusion remains uncertain pending completion of the phased remediation decision process required by the regulations.

• Groundwater. We have completed investigations of potential groundwater contamination and have submitted a report on the investigations finding that there is no PCB contamination, but some oil contamination of the groundwater.  We expect the regulators to require confirmatory long term groundwater monitoring at the site.  

• Soil. We have completed the investigation of soil contamination and submitted a report characterizing contamination to the regulators. Based on the results of this investigation, we believe that the contamination may be left in place and monitored, pursuant to a site-specific risk assessment, which is underway. However, this conclusion is subject to completion of a phased remediation decision process required by applicable regulations.

     We believe that the most likely form of remediation will be to leave existing contamination in place, encapsulate it, and monitor the effectiveness of the encapsulation.

     We estimate that the cost of the likely remediation above would approximate $400,000, and that amount has been recorded as a liability on our books and records.

     The Company is evaluating options for upgrading the wastewater treatment facilities at its Adams, Massachusetts plant. This work has been undertaken pursuant to an administrative Consent Order originally issued by the Massachusetts Department of Environmental Protection (“DEP”) on June 18, 2002. This order was amended on June 1, 2009 and on June 2, 2010.  The amended Order requires the implementation of a groundwater containment system following DEP review and approval of certain items required to be submitted by the Company in two parts, by July 1, 2010 and by October 1, 2010. The estimated capital cost of the groundwater containment system to allow continued operation of the wastewater treatment ponds through 2024 is $3 million. The amended Order also includes

14

MINERALS TECHNOLOGIES INC. AND SUBSIDIARY COMPANIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

the investigation by January 1, 2022 of options for ensuring that the facility's wastewater treatment ponds will not result in unpermitted discharge to groundwater.  Additional requirements of the amendment include the submittal by July 1, 2022 of a plan for closure of a historic lime solids disposal area. Preliminary engineering reviews completed in 2005 indicate that the estimated cost of wastewater treatment upgrades to operate this facility beyond 2024 may be between $6 million and $8 million. The Company estimates that the remaining remediation costs would approximate $400,000, which has been accrued as of July 4, 2010.

     The Company and its subsidiaries are not party to any other material pending legal proceedings, other than routine litigation incidental to their businesses.

REVIEW REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders

Minerals Technologies Inc.:

     We have reviewed the condensed consolidated balance sheet of Minerals Technologies Inc. and subsidiary companies as of July 4, 2010 and the related condensed consolidated statements of operations for the three-month and six-month periods ended July 4, 2010 and June 28, 2009, and the related condensed consolidated statements of cash flows for the six-month periods ended July 4, 2010 and June 28, 2009.  These condensed consolidated financial statements are the responsibility of the company's management.

     We conducted our review in accordance with the standards of the Public Company Accounting Oversight Board (United States).  A review of interim financial information consists principally of applying analytical procedures to financial data and making inquiries of persons responsible for financial and accounting matters.  It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States), the objective of which is the expression of an opinion regarding the financial statements taken as a whole.  Accordingly, we do not express such an opinion.

     Based on our review, we are not aware of any material modifications that should be made to the condensed consolidated financial statements referred to above for them to be in conformity with U.S. generally accepted accounting principles.

     We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet of Minerals Technologies Inc. and subsidiary companies as of December 31, 2009, and the related consolidated statements of income, shareholders' equity, and cash flows for the year then ended (not presented herein); and in our report dated February 25, 2010, we expressed an unqualified opinion on those consolidated financial statements.  In our opinion, the information set forth in the accompanying condensed consolidated balance sheet as of December 31, 2009 is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

Executive Summary

    Consolidated sales for the second quarter of 2010 increased 23% to $255.8 million from $208.6 million in the prior year. Income from operations was $27.5 million as compared with a loss of $41.6 million in the prior year. Included in loss from operations in the prior year was an impairment of assets charge of $37.5 million and restructuring charges of $9.6 million. Net income was $19.0 million as compared with a net loss of $40.9 million in the prior year.

     The Company continued to see improvement in all of the end markets we serve, particularly in steel, construction and automotive. In the prior year, weakness in these markets, due to the worldwide economic recession, resulted in significant drops in demand for our products. In the current year, improvement in the underlying markets and the resulting increase in volumes, coupled with the benefits derived from our announced restructuring programs and productivity improvements have led to improved operating performance in all product lines.

The Company continues to have a very strong balance sheet. Cash, cash equivalents and short-term investments were more than $345 million.  The impact of foreign exchange on cash and cash equivalents was a decline of $17.8 million due to the stronger dollar. Our cash flows from operations were $75.5 million, of which approximately $42 million was generated in the second quarter.  We have available credit lines of $177 million, our debt to equity ratio was 12%, and our current ratio was 4.1.

     We face some significant risks and challenges in the future:

· The industries we serve, primarily paper, steel, construction and automotive, have been adversely affected by the global economic climate. Future economic conditions remain uncertain. Our global business could be adversely affected by decreases in economic activity.

· Some of our customers may still experience further consolidations and shutdowns or may face increased liquidity issues, which could deteriorate the aging of our accounts receivable, increase our bad debt exposure and possibly trigger impairment of assets or realignment of our businesses.

· The reduced availability of credit in the financial markets could adversely affect the ability of our customers and/or our suppliers to obtain financing.

· Consolidations and rationalizations in the paper and steel industries concentrate purchasing power in the hands of fewer customers, increasing pricing pressure on suppliers such as Minerals Technologies Inc.

19

· Most of our Paper PCC sales are subject to long-term contracts that may be terminated pursuant to their terms, or may be renewed on terms less favorable to us.

· We are subject to volatility in pricing and supply availability of our key raw materials used in our Paper PCC product line and Refractory product line. Our ability to recover increased costs is uncertain and may become more difficult in this economic environment.

· We continue to rely on China for a significant portion of our supply of magnesium oxide in the Refractories segment which may be subject to uncertainty in availability and cost.

· Fluctuations in energy costs have an impact on all of our businesses.

· Changes in the fair market value of our pension assets, rates of return on assets, and discount rates could have a significant impact on our net periodic pension costs as well as our funding requirements.

· As we expand our operations abroad we face the inherent risks of doing business in many foreign countries, including foreign exchange risk, import and export restrictions, and security concerns.

· The Company’s operations, particularly in the mining and environmental areas (discharges, emissions and greenhouse gases), are subject to regulation by federal, state and foreign authorities and may be subject to, and presumably will be required to comply with, additional laws, regulations and guidelines which may be adopted in the future.

     The Company will continue to focus on innovation and new product development and other opportunities for continued growth as follows:

· Development of the filler-fiber composite program, which continues to undergo large-scale paper machine trials, to increase the fill-rate for uncoated freesheet paper.

· Increasing our sales of PCC for paper by further penetration of the markets for paper filling at both freesheet and groundwood mills, particularly in emerging markets.

· Further growth of the Company's PCC coating product line using the satellite model.

· Leverage the Company's expertise in crystal engineering, especially in helping papermakers customize PCC morphologies for specific paper applications.

· Development of unique calcium carbonates used in the manufacture of novel biopolymers, a new market opportunity.

· Rapid deployment of value-added formulations of refractory materials that not only reduce costs but improve performance.

· Continuing our penetration in emerging markets.

· Further growth of PCC produced for paper filling applications by working with industry partners to develop new methods to increase the ratio of PCC for fiber substitutions.

· Further proliferation of operational excellence principles into all aspects of the organization, including system infrastructure and lean principles.

· Explore selective acquisitions to fit our core competencies in minerals and fine particle technology.

     However, there can be no assurance that we will achieve success in implementing any one or more of these opportunities.

     Cash flows in the first six months of 2010 provided from operations were applied principally to fund capital expenditures, repay short term debt, repurchase shares of Company stock, and pay the Company's dividend to common shareholders.  Cash provided from operating activities amounted to $75.5 million in the first six months of 2010 as compared with $62.8 million for the same period last year.  The increase in cash provided from operations was primarily due to increased income levels partially offset by a change in working capital when compared with the prior year.

     Working capital is defined as trade accounts receivable, trade accounts payable and inventories. Working capital decreased approximately 1% from December 2009. Total days of working capital decreased to 54 days in the second quarter of 2010 from 59 days in the fourth quarter of 2009. This decrease was primarily attributable to reductions in raw materials inventories and increases in trade payables, partially offset by an increase in our trade receivables. The increase in receivables was primarily due to higher sales in the second quarter of 2010 than in the fourth quarter of the prior year.

28

    On February 22, 2010, the Company's Board of Directors authorized the Company's management to repurchase, at its discretion, up to $75 million of additional shares over the next two-year period. As of July 4, 2010, 204,620 shares have been purchased under this program at an average price of approximately $53.03 per share.

     On July 21, 2010, our Board of Directors declared a regular quarterly dividend on our common stock of $0.05 per share. No dividend will be payable unless declared by the Board and unless funds are legally available for payment.

     The following table summarizes our contractual obligations as of July 4, 2010:

Contractual Obligations

				Payments Due by Period
(millions of dollars)			Total		Less Than 1 Year		1-3 Years		3-5 Years		After 5 Years
Debt		$	97.2	$	4.6	$	8.0	$	84.6	$	--
Operating lease obligations			22.1		4.6		5.1		4.7		7.7
	Total contractual obligations	$	119.3	$	9.2	$	13.1	$	89.3	$	7.7

     The Company had $180 million in uncommitted short-term bank credit lines, of which $3.3 million were in use at July 4, 2010.  Our credit lines are primarily in the US, with approximately $10 million or 6% outside the US.  The credit lines are generally one year in term at competitive market rates at large well established institutions.  The Company typically uses its available credit lines to fund working capital requirement or local capital spending needs. We anticipate that capital expenditures for 2010 should be between $50 million and $75 million, principally related to the construction of PCC plants and other opportunities that meet our strategic growth objectives. We expect to meet our other long-term financing requirements from internally generated funds, uncommitted ba nk credit lines and, where appropriate, project financing of certain satellite plants.  The aggregate maturities of long-term debt are as follows: remainder of 2010 - $4.6 million; 2011 - $0.0 million; 2012 - $8.0 million; 2013 - $76.4 million; 2014 - $8.2 million; thereafter - $0.0 million.

Prospective Information and Factors That May Affect Future Results

     The Securities and Exchange Commission encourages companies to disclose forward-looking information so that investors can better understand companies' future prospects and make informed investment decisions.  This report may contain forward-looking statements that set out anticipated results based on management's plans and assumptions.  Words such as "believes," "expects," "plans," "anticipates," "estimates" and words and terms of similar substance, used in connection with any discussion of future operating or financial performance identify these forward-looking statements.

     Although we believe we have been prudent in our plans and assumptions, we cannot guarantee that the outcomes suggested in any forward-looking statement will be realized.  Achievement of future results is subject to risks, uncertainties and inaccurate assumptions.  Should known or unknown risks or uncertainties materialize, or should underlying assumptions prove inaccurate, actual results could vary materially from those anticipated, estimated or projected.  Investors should bear this in mind as they consider forward-looking statements and should refer to the discussion of certain risks, uncertainties and assumptions entitled "Cautionary Factors That May Affect Future Results" in Exhibit 99 to this Quarterly Report.

Recently Issued Accounting Standards

     In January 2010, the FASB issued guidance that requires new disclosures, and clarifies existing disclosure requirements, about fair value measurements. The clarifications and the requirement to separately disclose transfers of instruments between level 1 and level 2 of the fair value hierarchy are effective for interim reporting periods beginning after December 15, 2009; however, the requirement to provide purchases, sales, issuances and settlements in the level 3 roll forward on a gross basis is effective for fiscal years beginning after December 15, 2010.

     In October 2009, the FASB amended the accounting and disclosure requirements for revenue recognition.  These amendments, effective for fiscal years beginning on or after June 15, 2010, modify the criteria for recognizing

29

revenue in multiple element arrangements and the scope of what constitutes a non-software deliverable. The implementation of this guidance is not expected to have a material impact on our consolidated financial statements.

Critical Accounting Policies

     Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles.  The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities.

     On an ongoing basis, we evaluate our estimates and assumptions, including those related to revenue recognition, allowance for doubtful accounts, valuation of inventories, valuation of long-lived assets, pension plan assumptions, stock-based compensation assumptions, income taxes, income tax valuation allowances and litigation and environmental liabilities.  We base our estimates on historical experience and on other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that can not readily be determined from other sources.  There can be no assurance that actual results will not differ from those estimates.

ITEM 3.  Quantitative and Qualitative Disclosures about Market Risk

     Market risk represents the risk of loss that may impact our financial position, results of operations or cash flows due to adverse changes in market prices and foreign currency and interest rates.  We are exposed to market risk because of changes in foreign currency exchange rates as measured against the U.S. dollar.  We do not anticipate that near-term changes in exchange rates will have a material impact on our future earnings or cash flows.  However, there can be no assurance that a sudden and significant decline in the value of foreign currencies would not have a material adverse effect on our financial condition and results of operations.  Approximately 50% of our bank debt bears interest at variable rates; therefore our results of operations would only be affec ted by interest rate changes to such outstanding bank debt.  An immediate 10 percent change in interest rates would not have a material effect on our results of operations over the next fiscal year.     

     We do not enter into derivatives or other financial instruments for trading or speculative purposes.  When appropriate, we enter into derivative financial instruments, such as forward exchange contracts and interest rate swaps, to mitigate the impact of foreign exchange rate movements and interest rate movements on our operating results.  The counterparties are major financial institutions.  Such forward exchange contracts and interest rate swaps would not subject us to additional risk from exchange rate or interest rate movements because gains and losses on these contracts would offset losses and gains on the assets, liabilities, and transactions being hedged. We have open forward exchange contracts to purchase approximately $4.5 million of foreign currencies as of July 4, 20 10. The contracts mature between July 2010 and January of 2011.  The fair value of these instruments at July 4, 2010 was an asset of less than $0.1 million.

     In 2008, the Company entered into forward contracts to sell 30 million Euros as a hedge of its net investment in Europe. These contracts mature in October 2013. The fair value of these instruments at July 4, 2010 was an asset of $4.5 million.

ITEM 4.  Controls and Procedures

Evaluation of Disclosure Controls and Procedures

     As of the end of the period covered by this report, and under the supervision and with participation of the Company's management, including the Chief Executive Officer and the Chief Financial Officer, the Company carried out an evaluation of the effectiveness of the design and operation of the Company's disclosure controls and procedures, pursuant to Exchange Act Rule 13a-15(b).  Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the Company's disclosure controls and procedures were effective as of July 4, 2010.

     The Company is in the process of implementing a global enterprise resource planning ("ERP") system to manage its business operations.  As of July 4, 2010, all of our domestic locations were using the new system. The worldwide

30

implementation is expected to be completed over the next few years and involves changes in systems that include internal controls. Although the transition has proceeded to date without material adverse effects, the possibility exists that our migration to the new ERP system could adversely affect the Company's internal controls over financial reporting and procedures. We are reviewing each system as it is being implemented and the controls affected by the implementation of the new systems, and are making appropriate changes to affected internal controls as we implement the new systems. We believe that the controls as modified are appropriate and functioning effectively.    

Changes in Internal Control Over Financial Reporting

     There was no change in the Company's internal control over financial reporting (other than the ongoing implementation of the ERP system discussed above) during the quarter ended July 4, 2010 that has materially affected, or is reasonably likely to materially affect, the Company's internal control over financial reporting.

PART II.  OTHER INFORMATION

ITEM 1.  Legal Proceedings

     Certain of the Company's subsidiaries are among numerous defendants in a number of cases seeking damages for exposure to silica or to asbestos containing materials.  The Company currently has 305 pending silica cases and 28 pending asbestos cases.  To date, 1,160 silica cases and 4 asbestos cases have been dismissed. Most of these claims do not provide adequate information to assess their merits, the likelihood that the Company will be found liable, or the magnitude of such liability, if any.  Additional claims of this nature may be made against the Company or its subsidiaries.  At this time management anticipates that the amount of the Company's liability, if any, and the cost of defending such claims, will not have a material effect on its financial position or res ults of operations.

     The Company has not settled any silica or asbestos lawsuits to date.  We are unable to state an amount or range of amounts claimed in any of the lawsuits because state court pleading practices do not require identifying the amount of the claimed damage.  The aggregate cost to the Company for the legal defense of these cases since inception was approximately $0.1 million, the majority of which has been reimbursed by Pfizer Inc pursuant to the terms of certain agreements entered into in connection with the Company's initial public offering in 1992.  Our experience has been that the Company is not liable to plaintiffs in any of these lawsuits and the Company does not expect to pay any settlements or jury verdicts in these lawsuits.

Environmental Matters

     On April 9, 2003, the Connecticut Department of Environmental Protection issued an administrative consent order relating to our Canaan, Connecticut, plant where both our Refractories segment and Specialty Minerals segment have operations. We agreed to the order, which includes provisions requiring investigation and remediation of contamination associated with historic use of polychlorinated biphenyls ("PCBs") at a portion of the site. The following is the present status of the remediation efforts:

• Building Decontamination. We have completed the investigation of building contamination and submitted a report characterizing the contamination. We are awaiting review and approval of this report by the regulators. Based on the results of this investigation, we believe that the contamination may be adequately addressed by means of encapsulation through painting of exposed surfaces, pursuant to the Environmental Protection Agency's ("EPA") regulations and have accrued such liabilities as discussed below. However, this conclusion remains uncertain pending completion of the phased remediation decision process required by the regulations.

• Groundwater. We have completed investigations of potential groundwater contamination and have submitted a report on the investigations finding that there is no PCB contamination, but some oil contamination of the groundwater.  We expect the regulators to require confirmatory long term groundwater monitoring at the site.  

• Soil. We have completed the investigation of soil contamination and submitted a report characterizing contamination to the regulators. Based on the results of this investigation, we believe that the contamination may be left in place and monitored, pursuant to a site-specific risk assessment, which is underway. However, this conclusion is subject to completion of a phased remediation decision process required by applicable regulations.

     We believe that the most likely form of remediation will be to leave existing contamination in place, encapsulate it, and monitor the effectiveness of the encapsulation.

31

     We estimate that the cost of the likely remediation above would approximate $400,000, and that amount has been recorded as a liability on our books and records.

     The Company is evaluating options for upgrading the wastewater treatment facilities at its Adams, Massachusetts plant. This work has been undertaken pursuant to an administrative Consent Order originally issued by the Massachusetts Department of Environmental Protection (“DEP”) on June 18, 2002. This order was amended on June 1, 2009 and on June 2, 2010.  The amended Order requires the implementation of a groundwater containment system following DEP review and approval of certain items required to be submitted by the Company in two parts by July 1, 2010 and by October 1,2010. The estimated capital cost of the groundwater containment system to allow continued operation of the wastewater treatment ponds through 2024 is $3 million. The amended Order also includes the investigation by Jan uary 1, 2022 of options for ensuring that the facility's wastewater treatment ponds will not result in unpermitted discharge to groundwater.  Additional requirements of the amendment include the submittal by July 1, 2022 of a plan for closure of a historic lime solids disposal area. Preliminary engineering reviews completed in 2005 indicate that the estimated cost of wastewater treatment upgrades to operate this facility beyond 2024 may be between $6 million and $8 million. The Company estimates that the remaining remediation costs would approximate $400,000, which has been accrued as of July 4, 2010.

     The Company and its subsidiaries are not party to any other material pending legal proceedings, other than routine litigation incidental to their businesses.

RISK FACTORS

     The disclosure and analysis set forth in this report contains certain forward-looking statements, particularly statements relating to future actions, future performance or results of current and anticipated products, sales efforts, expenditures, and financial results.  From time to time, the Company also provides forward-looking statements in other publicly-released materials, both written and oral.  Forward-looking statements provide current expectations and forecasts of future events such as new products, revenues and financial performance, and are not limited to describing historical or current facts.  They can be identified by the use of words such as "expects," "plans," "anticipates," and other words and phrases of similar meaning.

     Forward-looking statements are necessarily based on assumptions, estimates and limited information available at the time they are made.  A broad variety of risks and uncertainties, both known and unknown, as well as the inaccuracy of assumptions and estimates, can affect the realization of the expectations or forecasts in these statements.  Consequently, no forward-looking statement can be guaranteed.  Actual future results may vary materially.

     The Company undertakes no obligation to update any forward-looking statements.  Investors should refer to the Company's subsequent filings under the Securities Exchange Act of 1934 for further disclosures.

     As permitted by the Private Securities Litigation Reform Act of 1995, the Company is providing the following cautionary statements which identify factors that could cause the Company's actual results to differ materially from historical and expected results.

·	Adverse General Economic, Business, and Industry Conditions
	The Company’s business and operating results have been and may in the future be adversely affected by the current US recession and other global economic conditions, including declining consumer and business confidence, volatile raw material prices, instability in credit markets, high unemployment, fluctuating interest rates and exchange rates, and other challenges that could affect the global economy. The Company’s customers and potential customers may experience deterioration of their businesses, cash flow shortages, and difficulty obtaining financing. As a result, existing or potential customers may reduce or delay their growth and investments and their plans to purchase products, and may not be able to fulfill their obligations in a timely fashion. Further, suppliers could experience similar conditions, which could impac t their ability to fulfill their obligations to the Company. Adversity within capital markets may impact future return on pension assets, thus resulting in greater future pension costs that impact the company’s results.  Accordingly, a continued adverse economic climate in the U.S. or abroad could result in decreases in the Company’s net revenue and profitability.
·	Growth Rate
	Sales and income growth of the Company depends upon a number of uncertain events, including the outcome of the Company's strategies of increasing its penetration into geographic markets such as Asia and Europe; increasing its penetration into product markets such as the market for papercoating pigments and the market for groundwood paper pigments; increasing sales to existing PCC customers by increasing the amount of PCC used per ton of paper produced; developing, introducing and selling new products such as filler-fiber composite materials for the paper industry; and acquisitions.  Difficulties, delays or failure of any of these strategies could affect the future growth rate of the Company.
·	Contract Renewals
	Generally, the Company's sales of PCC are pursuant to long-term evergreen agreements, initially ten years in length, with paper mills where 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 plant.  However, failure of a number of the Company's customers to renew or extend existing agreements on terms as favorable to the Company as those currently in effect could have a substantial adverse effect on the Company's results of operations, and could also result in impairment of the assets associated with the PCC plant.

·	Consolidation in Customer Industries, Principally Paper and Steel
	Several consolidations in the paper industry have taken place in recent years.  These consolidations could result in partial or total closure of some paper mills where the Company operates PCC satellites.  Such closures would reduce the Company's sales of PCC, except to the extent that they resulted in shifting paper production and associated purchases of PCC to another location served by the Company. Similarly, consolidations have occurred in the steel industry.  Such consolidations in the two major industries we serve concentrate purchasing power in the hands of a smaller number of papermakers and steel manufacturers, enabling them to increase pressure on suppliers, such as the Company.  This increased pressure could have an adverse effect on the Company's results of operations in the future.
·	Regulation and Litigation; Environmental Exposures
	The Company’s operations are subject to international, federal, state and local governmental environmental, health and safety, tax and other laws and regulations, and potentially to claims for various legal, environmental and tax matters.  The Company is currently a party in various litigation matters.  While the Company carries liability insurance, which it believes to be appropriate to its businesses, and has provided reserves for such matters, which it believes to be adequate, an unanticipated liability, arising out of such a litigation matter or a tax or environmental proceeding could have a material adverse effect on the Company’s financial condition or results of operations. In addition, future events, such as changes to or modifications of interpretations of existing laws and regulations, or enforcement polices, or further investigation or evaluation of the potential environmental impacts of operations or health hazards of certain products, may give rise to additional compliance and other costs that could have a material adverse effect on the Company.  State, national, and international governments and agencies have been evaluating climate-related legislation and regulation that would restrict emissions of greenhouse gases in areas in which we conduct business, and some such legislation and regulation have already been enacted or adopted.  Enactment of climate-related legislation or adoption of regulation that restrict emissions of greenhouse gases in areas in which we conduct business could have an adverse effect on our operations or demand for our products.  Our manufacturing processes, particularly the manufacturing process for PCC, use a significant amount of energy and, should energy prices increase as a result of such legislation or regulation, we may not be able to pass these increased costs on to purchasers of our products.  We cannot predict if or when currently proposed or additional laws and regulations regarding climate change or other environmental or health and safety concerns will be enacted or adopted.
·	New Products
	The Company is engaged in a continuous effort to develop new products and processes in all of its product lines.  Difficulties, delays or failures in the development, testing, production, marketing or sale of such new products could cause actual results of operations to differ materially from our expected results.
·	Competition; Protection of Intellectual Property
	The Company's ability to compete is based in part upon proprietary knowledge, both patented and unpatented.  The Company's ability to achieve anticipated results depends in part on its ability to defend its intellectual property against inappropriate disclosure as well as against infringement.  In addition, development by the Company's competitors of new products or technologies that are more effective or less expensive than those the Company offers could have a material adverse effect on the Company's financial condition or results of operations.
·	Risks of Doing Business Abroad
	As the Company expands its operations overseas, it faces increased risks of doing business abroad, including inflation, fluctuation in interest rates and currency exchange rates, changes in applicable laws and regulatory requirements, export and import restrictions, tariffs, nationalization, expropriation, limits on repatriation of funds, civil unrest, terrorism, unstable governments and legal systems, and other factors.  Adverse developments in any of these areas could cause actual results to differ materially from historical and expected results.
·	Availability and Cost of Raw Materials
	The Company depends in part on having an adequate supply of raw materials for its manufacturing operations, particularly lime and carbon dioxide for the PCC product line, and magnesia and alumina for its Refractory operations and on having adequate access to ore reserves of appropriate quality at its mining operations.  Unanticipated changes in the costs or availability of such raw materials, or in the Company's ability to have access to its ore reserves, could adversely affect the Company's results of operations.

Cyclical Nature of Customers' Businesses

The majority of the Company's sales are to customers in industries which have historically been cyclical paper, steel and construction.  The Company's exposure to variations in its customers' businesses has been reduced by the diversification of its portfolio of products and services; and by its geographic expansion.  Also, the Company has structured most of its long-term satellite PCC contracts to provide a degree of protection against declines in the quantity of product purchased, since the price per ton of PCC generally rises as the number of tons purchased declines.  In addition, many of the Company's product lines lower its customers' costs of production or increase their productivity, which should encourage them to use its products. In addition, our Processed Minerals and Specialty PCC product lines are affected by the domestic building and construction markets. The residential component of this market has experienced a significant slowdown which could have an adverse impact on future growth.  A sustained economic downturn in one or more of the industries or geographic regions that the Company serves, or in the worldwide economy, could cause actual results of operations to differ materially from historical and expected results.
