Comprehensive income includes net income and changes in accumulated other comprehensive income, primarily cumulative translation adjustments, for the period. (7) The company is organized into three geographic operating segments (North America, Europe and Other International), each of which includes a number of operating companies. Reportable segment information is presented in the following table: North Other Consolidated (In Thousands) America Europe International Reconciling totals Three Months Ended June 30, 2002 Sales to external customers $102,759 $29,206 $18,729 $ 25 $150,719 Intercompany sales 4,966 8,695 587 (14,248) Net income 7,516 982 710 276 9,484 Six Months Ended June 30, 2002 Sales to external customers 198,266 51,777 34,724 37 284,804 Intercompany sales 10,092 15,949 1,090 (27,131) Net income 15,102 969 1,214 183 17,468 Three Months Ended June 30, 2001 Sales to external customers 93,604 22,351 18,794 32 134,781 Intercompany sales 4,587 5,447 630 (10,664) Net income (loss) 5,939 (45) 1,024 56 6,974 Six Months Ended June 30, 2001 Sales to external customers 184,301 47,417 36,602 56 268,376 Intercompany sales 9,325 10,533 961 (20,819) Net income 12,488 519 1,767 47 14,821 Reconciling items consist primarily of intercompany eliminations and items reported at the corporate level.

(8) At June 30, 2002, accounts receivable of $63.9 million were owned by Mine Safety Funding Corporation, an unconsolidated wholly-owned bankruptcy-remote subsidiary of the company. The company held a subordinated interest in these receivables of $32.8 million, of which $31.8 million is classified as other receivables. Net proceeds to the company from the securitization arrangement were $30.0 million at June 30, 2002. At December 31, 2001, accounts receivable of $65.0 million were owned by Mine Safety Funding Corporation. The company held a subordinated interest in these receivables of $39.3 million, of which $38.3 million is classified as other receivables. Net proceeds to the company from the securitization arrangement were $25.0 million at December 31, 2001. The key economic assumptions used to measure the retained interest at June 30, 2002 were a discount rate of 4% and an estimated life of 2.4 months. At June 30, 2002, an adverse change in the discount rate or estimated life of 10% and 20% would reduce the fair value of the retained interest by $53,000 and $106,000, respectively. The effect of hypothetical changes in fair value based on variations in assumptions should be used with caution and generally cannot be extrapolated. Additionally, the effect on the fair value of the retained interest of changing a particular assumption has been calculated without changing other assumptions. In reality, a change in one factor may result in changes in others. (9) During the second quarter, the company acquired CGF Gallet based in Lyon, France for $15.0 million. The acquisition has been recorded in accordance with FAS 141, Business Combinations, which requires the purchase method of accounting and establishes specific criteria for recognition of intangible assets other than goodwill. Preliminary estimates indicate goodwill associated with the acquisition will be approximately $8.5 million. The final allocation of the purchase price is expected to be completed by December 31, 2002. Gallet is the leading European manufacturer of protective helmets for the fire service, as well as head protection for the police and military. This acquisition complements MSA's strong existing line of fire service products and provides the opportunity to capitalize on opportunities where Gallet is strong - such as in the law enforcement, military and aviation markets. Gallet is being integrated into the company's operations and its products will be marketed under the MSA Gallet name. Gallet's results of operations for May and June 2002 are included in the consolidated financial statements. The following unaudited pro forma summary presents information as if Gallet had been acquired January 1, 2001: Three Months Ended Six Months Ended June 30 June 30 ------------------------------ ---------------------------- (In thousands, except EPS) 2002 2001 2002 2001 ---- ---- ---- ---- Net sales $154,198 $140,468 $298,630 $279,751 Net income 9,637 7,134 18,444 15,140 Basic earnings per share 0.79 0.60 1.52 1.28 (10) Effective January 1, 2002, the company adopted the non-amortization provisions of FAS No. 142, Goodwill and Other Intangible Assets. Under this standard, goodwill and intangible assets with indefinite lives are not amortized, but are subject to impairment tests that must be performed at least annually. If goodwill amortization had been discontinued January 1, 2001, net income for the year ended December 31, 2001, would have increased by $1.4 million, or eleven cents per share. The transitional impairment tests on goodwill as of January 1, 2002 have been completed and did not indicate that an impairment write-down should be recorded. The effects of adopting the non-amortization provisions on net income and basic earnings per share for the three and six months ended June 30, 2002 and 2001 were as follows: In thousands Three Months Ended June 30 Six Months Ended June 30 -------------------------- ------------------------ Net Income Basic EPS Net Income Basic EPS ---------- --------- ---------- --------- 2002 2001 2002 2001 2002 2001 2002 2001 ---- ---- ---- ---- ---- ---- ---- ---- Reported net income $ 9,484 $ 6,974 $ 0.78 $ 0.59 $ 17,468 $ 14,821 $ 1.44 $ 1.25 Goodwill amortization 344 0.03 681 0.06 ------------------ ---------------- -------------------- ------------------ Adjusted net income $ 9,484 $ 7,318 $ 0.78 $ 0.62 $ 17,468 $ 15,502 $ 1.44 $ 1.31 ================== ================ ==================== ================== Intangible assets include non-compete agreements that will be fully amortized in 2003 and patents that will be fully amortized in 2005. These items are included in other noncurrent assets. At June 30, 2002, intangible assets totaled $304,000, net of accumulated amortization of $2.7 million. Intangible asset amortization expense is expected to be approximately $355,000 in 2002, $115,000 in 2003, and $55,000 in 2004. Changes in goodwill and intangible assets, net of accumulated amortization, during the six months ended June 30, 2002 were as follows: (In thousands) Goodwill Intangibles -------- ----------- Net balances at December 31, 2001 $ 33,722 $ 526 Additions to goodwill 8,782 Amortization expense (222) Translation 15 -------- ----------- Net balances at June 30, 2002 $ 42,519 $ 304 ======== =========== Gallet intangible assets other than goodwill, if any, will be identified by December 31,2002 and reported separately. (11) FAS No. 143, Accounting for Asset Retirement Obligations, addresses accounting for obligations associated with the retirement of tangible long-lived assets. The company will adopt FAS No. 143 effective January 1, 2003 and does not expect that the adoption of this statement will have a significant effect on its results of operations or financial position. FAS 146, Accounting for Costs Associated with Exit or Disposal Activities, requires that costs associated with exit or

disposal activities be recognized when the liability is incurred rather than at the date of commitment to an exit or disposal plan. The provisions of FAS 146 are effective for exit or disposal activities that are initiated after December 31, 2002. Early adoption is encouraged. The company does not expect that the adoption of this statement will have a significant effect on its results of operations or financial position

MANAGEMENT'S DISCUSSION AND ANALYSIS Forward-looking statements Certain statements contained in this report may constitute forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements involve a number of risks, uncertainties and other factors that could cause actual results to differ materially from expectations contained in such statements. Factors that may materially affect financial condition and future results include: global economic conditions; the threat of terrorism and its potential consequences; the timely and successful introduction of new products; timely and successful integration of acquisitions; the availability of funding in the fire service and homeland security markets; the ability of third party suppliers to provide key materials and components; market conditions affecting specialty chemical customers; liquidity; and interest and currency exchange rates. Corporate Initiatives During the second quarter of 2002, MSA acquired CGF Gallet, the leading European manufacturer of protective helmets for the fire service, as well as head protection for the police and military. This acquisition complements MSA's strong existing line of fire service products, and provides the opportunity to capitalize on emerging opportunities where Gallet is strong - such as in the law enforcement, military, and aviation markets. Gallet is being integrated into the company's operations and its products are being marketed under the MSA Gallet name. Results of operations Three months ended June 30, 2002 and 2001 Sales for the second quarter of 2002 were $150.7 million, an increase of $15.9 million, or 12%, from $134.8 million in the second quarter of 2001. Second quarter 2002 sales for North American operations of $102.8 million were $9.2 million, or 10%, higher than in the second quarter of last year. Shipments of respiratory protection products, including gas masks, respirators, and self-contained breathing apparatus, were significantly higher in 2002, reflecting continued strong product interest and demand in the homeland security and fire service markets. These sales gains were partially offset by somewhat lower sales of both portable and permanent instruments, primarily due to continuing sluggishness in industrial markets and capital spending. U.S.

exports of safety products were disappointing, affected by economic disturbances in key export country markets and, until recently, the strong U.S. dollar. Specialty chemical sales improved during the current quarter. In Europe, second quarter 2002 sales of $29.2 million were $6.9 million, or 31% higher than in second quarter 2001. The increase reflects higher local currency sales in continuing operations and the addition of Gallet following its acquisition. When stated in U.S. dollars, European sales were also favorably affected by currency exchange rate movements. Second quarter 2002 local currency sales for Other International operations were approximately 6% higher than in second quarter 2001 on strong shipments in South Africa. When stated in U.S. dollars, however, sales of Other International operations were flat, reflecting the strengthening of the U.S. dollar against African and South American currencies. Gross profit for the second quarter of 2002 was $56.0 million, an increase of $4.1 million, or 8%, from $51.9 million in second quarter 2001. The ratio of gross profit to sales was 37.2% in the second quarter of 2002 compared to 38.5% in the corresponding quarter last year. The lower gross profit percentage is primarily due to product mix changes. Selling, general and administration costs in the second quarter of 2002 were $37.0 million, an increase of $4.8 million, or 15%, compared to $32.2 million in second quarter 2001. The increase includes higher expenses in the U.S., post-acquisition expenses of Gallet, and the currency translation effects of the stronger Euro. Depreciation and amortization expense in second quarter 2002 was $6.3 million, a decrease of $200,000, or 3%, from $6.5 million in the corresponding quarter last year. The decrease includes the effect of discontinuing goodwill amortization in 2002 as prescribed by FAS No. 142. Goodwill amortization expense was $564,000 in the second quarter of 2001. The decrease in goodwill amortization expense was partially offset by the additional depreciation for Gallet assets, the translation effect of the stronger Euro, and regular asset acquisitions. Interest expense was $1.4 million in second quarters of both 2002 and 2001. Currency exchange gains were $1.1 million in second quarter 2002 compared to losses of $387,000 in the second quarter of last year. The current quarter gain relates primarily to the strengthening of Euro and Canadian dollar-denominated assets, partially offset by continued devaluation of the Argentine Peso. Other income was $2.3 million in the second quarter of 2002 compared to $72,000 for second quarter 2001. Other income in second quarter 2002 included a gain of $2.1 million on the sale of real estate development property in Pittsburgh.

Income before income taxes was $14.7 million for second quarter 2002 compared to $11.4 million in second quarter 2001, an increase of $3.2 million, or 28%. The effective income tax rate for the second quarter of 2002 was 35.3% compared to 39.0% in second quarter 2001. The lower rate in 2002 relates to proportionately higher income in lower tax rate countries and permanent differences. Net income in the second quarter of 2002 was $9.5 million, or 78 cents per basic share, compared to $7.0 million, or 59 cents per basic share, in the second quarter last year. Six months ended June 30, 2002 and 2001 Sales for the six months ended June 30, 2002 were $284.8 million, an increase of $16.4 million, or 6%, from $268.4 million last year. North American sales for the six months ended June 30, 2002 of $198.3 million were $14.0 million, or 8% higher than the same period last year. Higher shipments of gas masks and respirators to military and homeland security markets accounted for a significant portion of the improvement. Portable and permanent instrument sales were lower than in the same period last year, reflecting sluggishness in industrial markets. Sales of specialty chemicals were lower than in the first six months of 2001, primarily due to unusually strong shipments to pharmaceutical customers early in 2001. Sales in Europe for the six months ended June 30, 2002 of $51.8 million were $4.4 million, or 9% , higher than the same period in 2001. The increase reflects local currency sales growth and the addition of Gallet sales, following its acquisition during the second quarter. Local currency sales of Other International operations for the first six months of 2002 were approximately 5% higher than in the same period last year, with improvement primarily in South Africa and Brazil. When stated in U.S. dollars, however, Other International sales for the six months ended June 30, 2002 of $34.7 million were $1.9 million, or 5%, lower than last year due to currency exchange rate movements. Gross profit for the six months ended June 30, 2002 was $108.7 million, an increase of $3.8 million, or 4%, from $104.9 million in the first six months of 2001. The ratio of gross profit to sales was 38.2% in the six months ended June 30, 2002 compared to 39.1% in the corresponding period last year. The lower gross profit percentage is primarily due to sales mix changes. Selling, general and administration costs in the six months ended June 30, 2002 were $68.1 million, an increase of $3.1 million, or 5%, from $65.0 million in the same period

last year. The increase includes higher expenses in the U.S., the post-acquisition expenses of Gallet, and the currency translation effects of the stronger Euro. Depreciation and amortization expense was $12.3 million in the six months ended June 30, 2002, a decrease of $554,000, or 4%, from $12.9 million in the same period last year. The decrease is primarily due to the effect of discontinuing goodwill amortization in 2002 as prescribed by FAS No. 142. Goodwill amortization expense was $1.1 million for the six months ended June 30, 2001. The decrease in goodwill amortization expense was partially offset by the additional depreciation for Gallet assets, the translation effect of the stronger Euro, and regular asset acquisitions. Interest expense for the six months ended June 30, 2002 was $2.7 million, a decrease of $305,000, or 10%, from $3.0 million in the same period last year. Lower interest expense in 2002 reflects a $5 million reduction in notes payable during December 2001 and lower average short-term borrowings. Currency exchange gains were $552,000 in the six months ended June 30, 2002 compared to losses of $385,000 in the same period last year. The current year gain relates primarily to the strengthening of Euro and Canadian dollar-denominated assets, partially offset by continued devaluation of the Argentine Peso. Other income was $2.2 million for the six months ended June 30, 2002 compared to $493,000 in the first half of 2001. Other income in the first half of 2002 included a gain of $2.1 million on the sale of real estate development property in Pittsburgh. Income before income taxes was $28.2 million for the six months ended June 30, 2002 compared to $24.1 million in the first six months of 2001, an increase of $4.1 million, or 17%. The effective income tax rate for the six months ended June 30, 2002 was 38.1% compared to 38.6% in the same period last year. The lower effective rate in 2002 relates to proportionately higher income in lower tax rate countries and differences in permanent items. Net income in the six months ended June 30, 2002 was $17.5 million, or $1.44 per basic share, compared to $14.8 million, or $1.25 per basic share, in the first six months of 2001. Liquidity and Financial Condition Cash and cash equivalents decreased $6.0 million during the six months ended June 30, 2002 compared with a decrease of $8.6 million in the same period of 2001. Operating activities provided $22.3 million of cash in the six months ended June 30, 2002 compared to providing $9.6 million in the first half of last year. The improvement

reflects higher operating income and more favorable adjustments for non-cash income and expenses. Cash used for increases in net operating assets was also lower during the current year. Cash of $26.0 million was used for investing activities in the first half of 2002 compared with the use of $17.2 million in the same period last year. The increased use of cash for investing activities in 2002 was primarily related to the Gallet acquisition. The 2001 amounts include cash used for the acquisition of Surety Manufacturing and Testing, Ltd. and the cash proceeds from the sale of a safety products distribution business in Sweden. Financing activities used $2.9 million in the first half of 2002 and provided $104,000 in the same period last year. Higher cash provided by financing activities in 2001 related primarily to short term borrowings.
