Notes to CONDENSED CONSOLIDATED Financial Statements (UNAUDITED) Note 1 -- Basis of Presentation In the opinion of management, the accompanying condensed consolidated financial statements include all adjustments necessary to present fairly the financial position, results of operations and cash flows. However, the financial statements do not include all of the disclosures normally required by accounting principles generally accepted in the United States of America or those normally made in the Company's annual report on Form 10-K. Please refer to the Company's annual report on Form 10-K for the year ended December 31, 2001 for such disclosures. The condensed consolidated balance sheet as of December 31, 2001 was derived from the audited consolidated balance sheet as of that date. The results of operations for interim periods are not necessarily indicative of the results to be expected for the full year. The Company has reclassified certain amounts in prior periods to conform to the current presentation. Note 2 -- Contingencies The Company has been involved in certain environmental and other matters. Additionally, the Company has been involved in numerous legal actions relating to the use of certain latex products, which the Company distributes, but does not manufacture. The Company is one of many defendants. The Company has been released from the majority of the lawsuits. While two lawsuits remain, they are still in preliminary stages and it has not been determined whether the Company's products were involved. Based on information available, the Company believes there will not be a material adverse impact on financial position, results of operations, or liquidity, from these matters, either individually or in aggregate. Note 3 -- Restructuring Charges Through the third quarter of 2002, approximately $555,000 was charged against earnings as a result of certain strategic and operating changes initiated by the Company's management related to liquidating Acme United Limited (AUL), a subsidiary located in the United Kingdom. The restructuring charges consisted of a write-down of inventory of $206,000, accounting and legal costs of $95,000, lease cancellation costs of $90,000, a write-off of goodwill of $69,000, severance costs of $55,000, other closing costs of $22,000, a write-off of uncollectible account receivable of $9,000 and write-offs of equipment of $9,000. Approximately $36,000 remained in accrued restructuring charges at September 30, 2002 primarily related to accounting and legal costs. During the first nine months of 2002, the Company terminated five employees in the UK and paid severance costs related to those terminations of $55,000. There will be no further terminations or severance costs related to the restructuring. Also, approximately $59,000 of accounting and legal costs have been paid. Note 4 -- Change in Accounting Estimate The Company changed its estimated effective income tax rate in the third quarter as a result of a reduction in the anticipated annual taxable income in the US. As a result, the Company recorded a benefit for the change in estimate of approximately $395,000 ($.12 a share) in the third quarter. The income tax benefit is primarily due to income tax benefits in the US attributed to the liquidation of AUL. Note 5 -- Debt On August 2, 2002, the Company entered into a new revolving loan agreement with Wachovia Bank, N.A.. This agreement allows for borrowings up to a maximum of $10,000,000 based on a formula, which applies specific percentages to balances of accounts receivable and inventory. Interest is payable monthly and is charged at the LIBOR rate plus 1.75 percent. All outstanding borrowings are due on July 31, 2005. The Company also transferred its interest rate swap agreement, which fixes the effective interest rate at 7.18 percent for $3,500,000 of debt under the agreement. The swap agreement expires January 19, 2003. (9)

Note 6 -- New Accounting Standards As of January 1, 2002, the Company adopted Financial Accounting Standards Board Statement No. 142, Goodwill and Other Intangible Assets (FAS 142) and as such no longer amortizes goodwill but rather tests it annually for impairment. There was no impairment of goodwill at January 1, 2002. Had Statement No. 142 been in effect as of the beginning of 2001, amortization expense for the three and nine month periods ended September 30, 2001 would have been reduced by $7,000 and $21,000, respectively, increasing net income by the same amount. As of January 1, 2002, the Company also adopted the Emerging Issues Task Force consensus No. 00-25, Vendor Income Statement Characterization of Consideration Paid to a Reseller of a Vendor's Products (EITF 00-25). As such, the Company recognizes consideration paid to a reseller of its product as a reduction of the selling price of its products and, therefore, reduces revenue in the Company's statement of operations. The adoption of EITF 00-25 had no effect on net income. Selling, general and administrative expenses for the three and nine month periods ended September 30, 2001 have been reclassified to conform to the new classification resulting in a $749,000 and $2,536,000 decrease of selling, general and administrative expenses and net sales for these respective periods. As of January 1, 2001, the Company adopted Financial Accounting Standards Board Statement No. 133, Accounting for Derivative Instruments and Hedging Activities, which was issued in June 1998 and its amendments Statements 137, Accounting for Derivative Instruments and Hedging Activities--Deferral of the Effective Date of FASB Statement No. 133, and 138, Accounting for Derivative Instruments and Certain Hedging Activities, issued in June 1999 and June 2000, respectively (collectively referred to as Statement 133). As a result of adopting Statement 133, the Company recognizes all derivative financial instruments, such as interest rate swap contracts and foreign exchange contracts, in the consolidated financial statements at fair value regardless of the purpose or intent for holding the instrument. Changes in the fair value of derivative financial instruments are either recognized periodically in income or in shareholders' equity as a component of comprehensive income depending on whether the derivative financial instrument qualifies for hedge accounting, and if so, whether it qualifies as a fair value hedge or cash flow hedge. Generally, changes in fair values of derivatives accounted for as fair value hedges are recorded in income along with the portions of the changes in the fair values of the hedged items that relate to the hedged risk(s). Changes in fair values of derivatives accounted for as cash flow hedges, to the extent they are effective as hedges, are recorded in other comprehensive income net of deferred taxes. Changes in fair value of derivatives used as hedges of the net investment in foreign operations are reported in other comprehensive income as part of the cumulative translation adjustment. Changes in fair values of derivatives not qualifying as hedges are reported in income. The adoption of Statement 133, resulted in a cumulative effect of an accounting change of $104,277 decrease to other comprehensive income. (10)

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS For the Three and Nine Months Ended September 30, 2002 Results of Operations Special Event During the second quarter of 2002, the Company initiated liquidation procedures for Acme United Limited (AUL), a subsidiary located in the United Kingdom. For the year ended December 31, 2001, AUL recorded a net loss of $495,000 on net sales of $2.0 million, representing a sales decline of approximately $1.2 million or 38% from the prior year. Through September 2002, AUL recorded a net loss of approximately $222,000 before one time restructuring charges of $555,000. The restructuring charges are comprised mainly of severance, lease termination costs, and inventory write-offs. Net Sales Traditionally, the Company's sales are stronger in the second and third quarters, and weaker in the first and fourth quarters of the fiscal year due to the seasonal nature of the business specific to the back-to-school season. Consolidated net sales for the quarter ended September 30, 2002 were $7,867,000 compared with $8,265,000 for 2001, a 5% decrease. Net sales for the first nine months of 2002 were $24,020,000 compared with $25,070,000 for 2001, a 4% decrease. The sales decrease was mainly driven by a sales decline of 55% in the United Kingdom as the business was liquidated. Domestic sales were 1% higher in the first nine months of 2002 compared with the same period in 2001. Gross Profit The gross profit for the third quarter of 2002 was $2,663,000 (33.9% of net sales) compared to $2,722,000 (32.9% of net sales) for the third quarter of 2001. Gross profit for the first nine months of 2002 was 33.2% of net sales compared to 31.3% in the same period of 2001. Excluding the inventory write-down associated with the AUL liquidation gross profit was 34.0% of net sales for the first nine months of 2002. The introduction of new products and improved operating efficiencies in the USA were the main reasons for the improved gross margins. Selling, General and Administrative Expenses Selling, general and administrative ("SG&A") expenses for the third quarter of 2002 were $2,688,000 (34.2% of net sales) compared with $2,085,000 (25.6% of net sales) for the same period of 2001, an increase of $603,000. Major contributors to the spending increase were market research, new product development, fees in connection with the new global debt facility and one-time personnel expenses. SG&A expenses were 29.2% of net sales for the first nine months of 2002 versus 24.6% in the comparable period of 2001. The increase is primarily attributable to the same issues mentioned for the third quarter of 2002. Interest Expense Interest expense for the first nine months of 2002 was $487,000, compared with $621,000 for 2001, a $134,000 decrease. This is mainly attributable to the decline in debt. Total debt declined to $6.6 million at September 30, 2002 compared to $8.3 million at September 30, 2001. Income Taxes The Company changed its estimated effective income tax rate in the third quarter as a result of a reduction in the anticipated annual taxable income in the US. As a result, the Company recorded a benefit for the change in estimate of approximately $395,000 ($.12 a share) in the third quarter. The income tax benefit is primarily due to income tax benefits in the US attributed to the liquidation of AUL. (11)

Net Income Net income for the third quarter of 2002 was $270,000, or 8 cents per share (diluted), compared to a net income of $405,000, or 11 cents per share (diluted) for the same period of 2001. Net income for the first nine months of 2002 was $619,000, or 17 cents per share (diluted), compared to a net income of $1,100,000, or 30 cents per share (diluted) for the same period of 2001. (12)

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS-Continued For the Nine Months Ended September 30, 2002 Financial Condition Liquidity and Capital Resources The Company's working capital, current ratio and long-term debt to equity ratio follow: September 30, 2002 December 31, 2001 ------------------ ------------------ Working capital................... $9,673,000 $8,762,000 Current ratio..................... 2.51 to 1 2.14 to 1 Long term debt to equity ratio.... .39 .33 During the first nine months of 2002, total debt increased by $962,000 compared to total debt at December 31, 2001 principally as a result of net additional short-term borrowings to fund higher accounts receivable due to seasonal sales volume. On August 2, 2002, the Company entered into a new revolving loan agreement with Wachovia Bank, N.A. This agreement allows for borrowings up to a maximum of $10,000,000 based on a formula, which applies specific percentages to balances of accounts receivable and inventory. Interest is payable monthly and is charged at the LIBOR rate plus 1.75 percent. All outstanding borrowings are due on July 31, 2005. The Company also transferred its interest rate swap agreement to Wachovia Bank, N.A., which fixes the effective interest rate to 7.18 percent for $3.5 million of debt through January 19, 2003. Cash expected to be generated from operating activities, together with funds available under its existing loan agreement, are expected, under current conditions, to be sufficient to finance the Company's planned operations over the next twelve months. Over that same period, the Company does not expect to make significant investments in plant, property, and equipment. Safe Harbor for Forward-looking Statements Forward-looking statements in this report, including without limitation, statements related to the Company's plans, strategies, objectives, expectations, intentions and adequacy of resources, are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995.
