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. These adjustments are of a normal recurring nature. However, the financial statements do not include all of the disclosures normally required by accounting principles generally accepted in the United States 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, 2002 for such disclosures. The condensed consolidated balance sheet as of December 31, 2002 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. Note 2 -- Contingencies The Company has been involved in certain environmental and other matters. Additionally, the Company is involved in one legal action relating to the use of certain latex products, which the Company distributes, but does not manufacture. The Company is one of many defendants in this suit, which is still in the 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 During the second quarter of 2002, approximately $565,000 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, write-off of goodwill of $70,000, severance costs of $60,000, other closing costs of $19,000, write-off of uncollectible account receivable of $15,000, and write-offs of equipment of $10,000. Approximately $39,000 and $215,000 remained in accrued restructuring charges at June 30, 2003 and 2002, respectively. Note 4 -- Accounting for Stock-Based Compensation At June 30, 2003, the Company has one stock-based employee compensation plan. The Company has elected to adopt the disclosure only provisions of Statement of Financial Accounting Standards No. 123, Accounting for Stock-Based Compensation, and continues to measure costs for its employee stock compensation plans by using the accounting methods prescribed by APB Opinion No. 25, Accounting for Stock Issued to Employees, which allows that no compensation cost be recognized unless the exercise price of the options granted is greater than the fair market value of the Company's stock at date of grant. Accordingly, no stock-based employee compensation cost is reflected in net income, as all options granted had an exercise price equal to the market value of the underlying common stock on the date of grant. The following table illustrates the effect on net income and earnings per share as if the Company had applied the fair value method under SFAS No. 123, Accounting for Stock Based Compensation, to stock-based employee compensation: 7

Three Months Ended Six Months Ended June 30 June 30 ------------------------------ ----------------------------- 2003 2002 2003 2002 -------------- ------------- ------------ -------------- Net income, as reported $ 614,998 $ 227,198 $ 692,832 $ 348,901 Deduct: Total stock-based employee compensation expense determined under fair value based method for all awards, net of related income tax effects 35,477 32,858 50,770 51,374 -------------------------------------------------------------- Pro forma net income $ 579,521 $ 194,340 $ 642,062 $ 297,527 ============================================================== Basic-as reported $ 0.18 $ 0.07 $ 0.21 $ 0.10 Basic-pro forma 0.17 0.06 0.19 0.09 Diluted-as reported $ 0.17 $ 0.06 $ 0.20 $ 0.10 Diluted-pro forma 0.16 0.05 0.18 0.08 Note 5 -- Litigation Settlement As a result of significant developments in the first quarter of 2003, the Company's German subsidiary settled litigation for $175,000. This amount exceeded previous accruals by $153,000 and was charged to expense in the first quarter of 2003. Note 6 -- Income Taxes In 2002, the Company recognized a significant one-time income tax benefit associated with liquidating its UK business. The benefit recognized was substantially in excess of income taxes computed at the statutory rate. In 2003, increased losses from the European subsidiary resulted in a high effective income tax rate. 8

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS For the Three and Six Months Ended June 30, 2003 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 June 30, 2003 were $10,142,000 compared with $9,398,000 for 2002, an 8% increase. Net sales for the first six months of 2003 were $17,331,000 compared with $16,153,000 for 2002, a 7% increase. Excluding the favorable effect of currency gains in Canada and Europe net sales for the first six months increased 5%. The sales increase was mainly driven by growth in the U.S. due to the success of new product launches. International sales were down 3% in local currency principally due to discontinuing certain product lines in the UK business and a generally weak economy in Germany. Gross Profit The gross profit for the second quarter of 2003 was $3,921,000 (38.7% of net sales) compared to $3,371,000 (35.9% of net sales) for the second quarter of 2002. This comparison excludes the 2002 inventory write-down associated with the Acme United Limited (AUL) liquidation (See Special Event below). Gross profit for the first six months of 2003 was 39.3% of net sales compared to 34.1% in the same period of 2002. The introduction of new products coupled with improved product mix in the U.S., positive impacts from product rationalization efforts in Europe and overall productivity gains were the main reasons for the improved gross margins. Selling, General and Administrative Expenses Selling, general and administrative ("SG&A") expenses for the second quarter of 2003 were $2,906,000 (28.7% of net sales) compared with $2,381,000 (25.3% of net sales) for the same period of 2002, an increase of $545,000. SG&A expenses were 30.0% of net sales for the first six months of 2003 versus 26.8% in the comparable period of 2002. Major contributors to the increase were market research, new product development and the addition of sales executives in Canada and Europe. Interest Expense Interest expense for the first six months of 2003 was $152,000, compared with $310,000 for 2002, a $158,000 decrease. This is mainly attributable to the decline in debt and lower interest rates. Total debt declined to $6,066,000 million at June 30, 2003 compared to $8,174,000 million at June 30, 2002. Other Expense Net other expense was $135,000 in the first six months of 2003 compared to net other income of $122,000 in the first six months of 2002. The change from 2002 primarily relates to the settlement of a $175,000 lawsuit in Germany in March of 2003 and the gain on sale of equipment in 2002. Income Before Income Taxes Income before income taxes was $958,000 in the second quarter of 2003 compared with $299,000 in the second quarter of 2002, an increase of $659,000. Excluding restructuring costs associated with the AUL liquidation in the second quarter of 2002, pretax income increased by $94,000, or 11%. Income before income taxes was $1,310,000 for the first six months of 2003 compared with $437,000 in the first six months of 2002. Pretax income for the U.S. business was $1,644,000 compared to $1,283,000 in 2002. The European operations lost $451,000 including a one-time expense of $175,000 for settlement of a lawsuit. Excluding restructuring charges, the pretax loss in Europe for the first six months of 2002 was $281,000. 9

Income Taxes Income tax expense for the second quarter of 2003 was $343,000 compared to $72,000 in the second quarter of 2002. Income tax expense for the first six months of 2003 was $617,000 compared to $88,000 in the first six months of 2002. In 2002, the Company recognized a significant one-time income tax benefit associated with liquidating its UK business. The benefit recognized was substantially in excess of income taxes computed at the statutory rate. In 2003, increased losses from the European subsidiary resulted in a high effective income tax rate. Net Income Net income for the second quarter of 2003 was $594,000, or 17 cents per share (diluted), compared to a net income of $227,000, or 6 cents per share (diluted) for the same period of 2002. Net income for the first six months of 2003 was $672,000, or 19 cents per share (diluted), compared to a net income of $349,000, or 10 cents per share (diluted) for the same period of 2002. Special Event During the second quarter of 2002, the Company initiated liquidation procedures for AUL. Through June 2002, AUL recorded a net loss of approximately $187,000, before one time restructuring charges of $565,000. The restructuring charges were comprised mainly of severance, lease termination costs, and inventory write-offs. These losses were offset by tax benefits of approximately $418,000 in the United States for the same period. 10

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS-Continued For the Three and Six Months Ended June 30, 2003 Financial Condition Liquidity and Capital Resources The Company's working capital, current ratio and long-term debt to equity ratio follow: June 30, 2003 December 31, 2002 ------------------ ------------------ Working capital....................... $9,744,000 $8,516,000 Current ratio......................... 2.15 to 1 2.33 to 1 Long-term debt to equity ratio........ 22.0% 24.0% During the first six months of 2003, total bank debt increased by $940,000 compared to total debt at December 31, 2002, principally as a result of net additional short-term borrowings to fund inventory purchases in anticipation of next quarter's seasonal sales volume. The Company has a revolving loan agreement, which 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. As of June 30, 2003, $5,025,612 was outstanding and $3,645,788 was available for borrowing under this agreement. Maturities of long-term debt follow: 2004 - $2,913,000, 2005 - $1,120,000, and 2006 - $992,612. All outstanding borrowings are due on July 31, 2005. Cash expected to be generated from operating activities, together with funds available under the 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.
