(8) FAS No. 125, Accounting for Transfers and Servicing of Financial Assets and Extinguishment of Liabilities, applies a control-oriented, financial components approach to financial-asset-transfer transactions. Financial assets, net of retained interests, are removed from the balance sheet when the assets are sold and control is surrendered. In September 2000, FAS No. 125 was replaced by FAS 140 which revised certain accounting and disclosure requirements for securitizations and other transfers of financial assets, but carried over most FAS No. 125 provisions. At June 30, 2001, accounts receivable of $57.9 million were owned by Mine Safety Funding Corporation (MSF), an unconsolidated wholly-owned special purpose bankruptcy-remote subsidiary of the company. The company held a subordinated interest in these receivables of $28.0 million, of which $27.0 million is classified as other receivables. Net proceeds to the company from the securitization arrangement were $29.0 million at June 30, 2001. The key economic assumptions used to measure the retained interest at June 30, 2001 were a discount rate of 6 1/2% and an estimated life of 2.4 months. At June 30, 2001, an adverse change in the discount rate or estimated life of 10% and 20% would reduce the fair value of the retained interest by $75,000 and $150,000, 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) Effective January 1, 2001, the company adopted FAS No. 133, Accounting for Derivative Instruments and Hedging Activities, which establishes accounting and reporting standards for derivative instruments, including those embedded in other contracts. Adoption of this standard did not have a significant effect on the company's results or financial position. (10) The company will adopt FAS No. 142, Goodwill and Other Intangible Assets, effective January 1, 2002. Under FAS No. 142 goodwill and other intangible assets with indefinite lives are not amortized, but are subject to periodic impairment tests that must be performed at least annually. Adoption of this standard will reduce amortization expense beginning in 2002; however, impairment tests could result in future periodic write-downs. The company is reviewing the provisions of this statement and its impact on results of operations and financial position. 5

MANAGEMENT'S DISCUSSION AND ANALYSIS Forward-looking statements - -------------------------- This report contains "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. Such forward-looking statements may include, without limitation, statements regarding expectations for new products, cost reduction programs, fire department funding program, liquidity, sales and earnings, and market risk. Actual results may differ from expectations contained in such forward-looking statements and can be affected by any number of factors, many of which are outside of management's direct control. Among the factors that could cause such differences are the effects of cost reduction efforts, market acceptance of new products, the company's ability to fulfill order backlogs, market fire service market conditions, the economic environment, and interest and currency exchange rates. Results of operations - ---------------------- Three months ended June 30, 2001 and 2000 - ----------------------------------------- Sales for the second quarter of 2001 were $134.8 million, an increase of $13.1 million, or 11%, from $121.7 million in the second quarter of 2000. Second quarter 2001 sales for North American operations were 19% higher than in the second quarter of last year. Sales to the fire service market improved significantly, reflecting the introduction of the Evolution line of thermal imaging cameras and the CairnsHelmets line of firefighter head protection and continuing strength in shipments of breathing apparatus. Second quarter 2001 sales also include higher shipments of gas masks, breathing apparatus, and goggles to the U.S. government. Specialty chemical sales in second quarter 2001 were 18% higher than last year's second quarter. Specialty chemical sales to pharmaceutical industry customers were depressed during most of 2000. Incoming orders of safety products exceeded shipments in second quarter 2001, resulting in higher backlog. The increase includes an order from the Chicago Fire department for more than 1,000 self-contained breathing apparatus. Shipments on this order began in June and are expected to be completed in September. Despite the increase in safety products order backlog during the quarter, the company believes that fire service orders are being delayed by continued uncertainty in the timing and selection of recipients of funding to be granted to U.S. fire departments under the Federal Emergency Management Agency (FEMA) Assistance to Firefighters Program. This delay in fire department orders has been observed by other suppliers to the fire service market, and some expect that orders could be strong later in the year from departments that receive FEMA funding 6

and also those who do not but will choose to expend other resources. Specialty chemical order backlog decreased sharply during the current quarter. In Europe, second quarter 2001 sales to external customers were 8% lower than in second quarter 2000. Increases in local currency sales in some markets were more than offset by currency exchange rate movements. Local currency sales growth in the current quarter occurred primarily in Germany. Sales in other European companies, were mixed, but overall, were somewhat lower for the quarter. Second quarter 2001 local currency sales for other international operations were 19% higher than in second quarter 2000, reflecting strong shipments in most markets. However, currency exchange effects reduced U.S. dollar sales growth of other international operations to 1%. Gross profit for the second quarter of 2001 was $51.9 million, an increase of $8.6 million, or 20%, from $43.3 million in second quarter 2000. The ratio of gross profit to sales was 38.5% in the second quarter of 2001 compared to 35.6% in the corresponding quarter last year. The improved gross profit percentage reflects reductions in North American manufacturing costs. Selling and administration costs in the second quarter of 2001 were $32.2 million, a decrease of $1.2 million, or 4%, from $33.4 million in the second quarter of 2000. The decrease occurred in European and other international operations and reflects lower reorganization charges in 2001 and the currency translation effect of the strong U.S. dollar. Depreciation and amortization expense in second quarter 2001 was $6.5 million, an increase of $688,000, or 12%, over $5.8 million in the corresponding quarter last year. The increase is primarily due to depreciation and goodwill amortization associated with acquisitions made in mid-2000 and early 2001. Interest expense was $1.4 million in second quarter 2001 compared to $877,000 in second quarter 2000. Higher interest expense in the current year reflects the additional debt required for the June 2000 repurchase of common stock from the family of a co-founder and the August 2000 acquisition of Cairns Helmets. Other income was $72,000 for second quarter 2001 compared to $830,000 in second quarter 2000. Other income in the second quarter of 2000 included a gain of $700,000 on the sale of property. Income before income taxes was $11.4 million for second quarter 2001 compared to $4.0 million in second quarter 2000. The effective income tax rate for the second quarter of 2001 was 39.0% compared to 29.5% in second quarter 2000. The lower effective rate in 2000 was related to tax 7

benefits on international operating losses, primarily in Germany, and adjustments to prior year foreign sales corporation tax benefits in the U.S. Net income in the second quarter of 2001 was $7.0 million, or 59 cents per basic share, compared to $2.8 million, or 22 cents per basic share, in the second quarter last year. Six months ended June 30, 2001 and 2000 - --------------------------------------- Sales for the six months ended June 30, 2001 were $268.4 million, an increase of $17.5 million, or 7%, from $250.9 million last year. North American sales for the first six months of 2001 were 13% higher than the same period last year. Shipments of thermal imaging cameras and helmets to the fire service market; gas masks and goggles to defense and civilian preparedness markets; and helmets for construction and industrial markets all improved significantly. Instrument sales were also higher, reflecting new product introductions. Sales of specialty chemicals were significantly higher than in the first six months of 2000, which experienced delayed orders from pharmaceutical industry customers. Incoming orders for safety products exceeded sales during the first six months of 2001, particularly in government markets, resulting in a higher backlog. Specialty chemical order backlog decreased during the first six months of 2001. Sales in Europe for the first six months of 2001 were 8% lower than the same period in 2000. Modest local currency sales growth was more than offset by currency exchange rate movements when stated in U.S. dollars. The local currency sales improvement occurred primarily in Germany. Local currency sales of other international operations for the first six months of 2001 were 18% higher than in the same period last year, with all markets showing improvement. When stated in U.S. dollars, however, other international sales increased 2% due to currency exchange rate movements. Local currency sales were higher in all geographic markets, but particularly Australia, Brazil and South Africa. Gross profit for the six months ended June 30, 2001 was $104.9 million, an increase of $11.2 million, or 12%, from $93.7 million in the first six months of 2000. The ratio of gross profit to sales was 39.1% in the six months ended June 30, 2001 compared to 37.3% in the corresponding period last year. The higher gross profit percentage reflects manufacturing cost reductions and favorable cost adjustments on several large orders. Selling, general and administration costs in the six months ended June 30, 2001 were $65.0 million, a decrease of $1.0 million, or 2%, from $66.0 million in the same period last year. The decrease occurred in European and other international operations and reflects lower reorganization charges in 2001 and the translation effect of the strong U.S. dollar. 8

Depreciation and amortization expense was $12.9 million in the six months ended June 30, 2001 an increase of $1.1 million, or 9%, from $11.8 million in the same period last year. The increase is primarily due to depreciation and goodwill amortization associated with acquisitions made in mid-2000. Interest expense for the six months ended June 30, 2001 was $3.0 million, an increase of $1.3 million, or 76%, from $1.7 million in the same period last year. Higher interest expense in 2001 relates to mid-2000 borrowings to finance acquisitions and stock repurchases. Other income was $493,000 for six months ended June 30, 2001 compared to $1.9 million in the first half of 2000. Other income in the first half of 2000 included $1.5 million in gains on sales of property and the Merrillville repair business. Income before income taxes was $24.1 million for the six months ended June 30, 2001 compared to $16.3 million in the first six months of 2000, an increase of $7.8 million or 48%. The effective income tax rate for the six months ended June 30, 2001 was 38.6% compared to 37.0% in the same period last year. The lower effective rate in 2000 was due to tax benefits on international operating losses, primarily in Germany, and adjustments in the U.S. related to prior year foreign sales corporation tax benefits. Net income in the six months ended June 30, 2001 was $14.8 million, or $1.25 per basic share, compared to $10.3 million, or 81 cents per basic share, in the first six months of 2000. Liquidity and Financial Condition - --------------------------------- Cash and cash equivalents decreased $8.6 million during the first half of 2001 compared with an increase of $239,000 in the first half of 2000. Operating activities provided $9.6 million of cash in first half of 2001 compared to providing $30.6 million in the same period last year. Lower cash provided by operations in 2001 is related to changes in working capital, primarily receivables and inventory. During the first half of 2001, inventory and receivables increased, while in the same period last year these items were reduced. Cash of $17.2 million was used for investing activities in the first half of 2001 compared with the use of $11.9 million in 2000. The increased use of cash is primarily related to the acquisition of Surety Manufacturing and Testing, Ltd. in February 2001 and manufacturing and e-business system property additions. Financing activities provided $104,000 in the first half of 2001 and used $18.1 million in the same period last year. Higher use of cash in 2000 related to the June 2000 repurchase of common stock from the family of a co-founder. 9

Available credit facilities and internal cash resources are considered adequate to provide for future operations, capital requirements and dividends to shareholders. Financial Instrument Market Risk - -------------------------------- There have been no material changes in the company's financial instrument market risk during the first six months of 2001. For additional information, refer to page 17 of the company's Annual Report to Shareholders for the year ended December 31, 2000. 10
