Page 5 <Page> MINNTECH CORPORATION NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) NOTE 1 - FINANCIAL INFORMATION The unaudited interim condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission; accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted. These unaudited interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes in the Company's Annual Report on Form 10-K for the year ended March 31, 2001 as filed with the Securities and Exchange Commission. The Company adopted a universal calendar for financial reporting beginning in the first quarter of fiscal 2001. A fiscal year will include either 52 or 53 weeks in total. This change in reporting is not materially different from prior years. Effective April 1, 2000, Minntech modified their revenue recognition policy for certain equipment sales and certain product shipments, resulting in a cumulative effect of a change in accounting. The cumulative effect of this accounting change was $.219 million ($.136 million, net of tax). The accounting change did not have a material effect on revenue or quarterly earnings during fiscal 2001. Minntech has restated its results for the thirteen week period ended July 1, 2000. See further discussion of this matter in the Company's Annual Report on Form 10-K for the year ended March 31, 2001. In the opinion of management, the unaudited interim condensed consolidated financial statements reflect all adjustments necessary for a fair presentation of the interim periods. NOTE 2 - LINE OF CREDIT At June 30, 2001, the Company had a line of credit with a commercial bank which allowed the Company to borrow up to $10 million on an unsecured basis at the prime rate of interest (6.75% at June 30, 2001) or the indexed London Interbank Offered Rate (LIBOR). As of June 30, 2001, the Company had no outstanding borrowings under the line of credit. This credit line expires on September 30, 2002. NOTE 3 - EARNINGS/(LOSS) PER SHARE The following table reconciles the numerators and denominators of the basic and diluted earnings/(loss) per share computations for the quarter ended June 30, 2001 and July 1, 2000. <Table> <Caption> (in thousands, except per share amounts) Basic Effect of Dilutive Diluted Quarter ended June 30, 2001 Earnings Per Share Stock Options Earnings Per Share - ---------------------------------------------------------------------------------------------------------------- Net earnings $ 1,204 $ 1,204 Weighted average common shares outstanding 6,681 27 6,708 Per share amount $ .18 $ .18 Quarter ended July 1, 2000 - ---------------------------------------------------------------------------------------------------------------- Net loss $ (197) $ (197) Weighted average common shares outstanding 6,682 6,682 Per share amount $ (.03) $ (.03) </Table> Page 6 <Page> MINNTECH CORPORATION NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) NOTE 3 - EARNINGS PER SHARE (CONTINUED) Outstanding stock options to purchase 280,195 and 588,049 shares of common stock as of June 30, 2001 and July 1, 2000, respectively, were not included in the computation of diluted earnings per share because the options' exercise prices were greater than the average market price of the common stock during the period. NOTE 4 - COMPREHENSIVE INCOME The components of comprehensive income are as follows: <Table> <Caption> (dollars in thousands) Quarter ended Quarter ended June 30, 2001 July 1, 2000 - -------------------------------------------------------------------------------------- Net earnings/(loss) $ 1,204 $ (61) Other comprehensive income: Foreign currency translation, net (275) 26 ------------------------------------------ Total other comprehensive income (275) 26 ----------------------------------------- Total comprehensive income/(loss) $ 929 $ (35) ========================================== </Table> The accumulated other comprehension income balance as of June 30, 2001 is solely comprised of foreign currency translation.

These segments, which are based upon products, services and industry, are Dialysis Products, Cardiosurgery Products and Other Developing Businesses. Management of these segments includes responsibility for different product lines and services on a geographic basis, including accountability for revenues as well as sales and marketing costs. Page 7 <Page> MINNTECH CORPORATION NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) NOTE 6 - SEGMENT DATA AND SIGNIFICANT CUSTOMERS (CONTINUED) The Dialysis Product segment includes supplies, concentrates, reprocessing services and electronic equipment for hemodialysis treatment of patients with chronic kidney failure or end-stage renal disease. Included in the Cardiosurgery Products segment are oxygenators and hemoconcentrators which are used during open-heart surgery, and hemofilters, which are used in acute renal failure. Developing Businesses include filtration and separation and endoscope reprocessing product lines. Research and development is managed at the corporate level. Resource decisions and performance assessment is managed by corporate officers. Research and development expenses are monitored by project and allocated to their respective segments. Corporate and unallocated represent costs that are not assigned to reportable segments. Therefore, management does not represent that these segments, if operated independently, would report the operating income and other financial information shown below. The table below presents information about reportable segments for the quarter ended June 30, 2001 and July 1, 2000, respectively.

(2) Identifiable segment assets include accounts receivable; property plant and equipment; inventories; and long term notes receivable. Additional assets included in Corporate and Unallocated primarily include cash and short-term investments, capitalized patent costs, deferred income taxes, goodwill, land and certain prepaid expenses. SIGNIFICANT CUSTOMERS During the first quarter ended June 30, 2001 no individual customer sales totals represented 10% or more or total revenues. Page 8 <Page> MINNTECH CORPORATION NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) NOTE 7 - ACCOUNTING PRONOUNCEMENTS In June 1998, the Financial Accounting Standards Board "FASB," issued Statement of Financial Accounting Standard No. 133 "Accounting for Derivative Instruments and Hedging Activities." This statement, which had to be adopted by the Company for transactions entered into beginning April 1, 2001, established new standards for recognition and measurement of derivatives and hedging activities. The adoption of this statement did not have a material effect on the Company's financial statements. In the fourth quarter of 2001, the Company adopted the Financial Accounting Standards Board's Emerging Issues Task Force (EITF) No. 00-10, "Accounting for Shipping and Handling Fees and Costs." EITF No. 00-10 requires companies to classify as revenue all amounts billed to customers in a sales transaction, including those amounts related to shipping and handling. The adoption of EITF No. 00-10 has resulted in the reclassification of certain freight amounts invoiced from cost of goods sold to revenue. The effect on the Company's Consolidated Statement of Operations was to increase cost of sales and increase revenue by $822 and $745 in the first quarter of fiscal 2002 and 2001, respectively. These reclassifications did not effect consolidated net earnings/(loss). In July 2001, the Financial Accounting Standards Board issued Statements of Financial Accounting Standards No. 141, Business Combinations ("FAS 141") and No. 142, Goodwill and Other Intangible Assets ("FAS 142"). FAS 141 requires all business combinations initiated after June 30, 2001 to be accounted for using the purchase method. Under FAS 142, goodwill and intangible assets with indefinite lives are no longer amortized but are reviewed annually (or more frequently if impairment indicators arise) for impairment. Separable intangible assets that are not deemed to have indefinite lives will continue to be amortized over their useful lives (but with no maximum life). Upon adoption of FAS 142, amortization of goodwill recorded for business combinations consummated prior to July 1, 2001 will cease, and intangible assets acquired prior to July 1, 2001 that do not meet the criteria for recognition under FAS 141 will be reclassified to goodwill. The amortization provisions of FAS 142 apply to goodwill and intangible assets acquired after June 30, 2001. Companies are required to adopt FAS 142 for fiscal years beginning after December 15, 2001, but early adoption is permitted. The Company will adopt FAS 142 on April 1, 2002, the beginning of fiscal 2003. In connection with the adoption of FAS 142, the Company will be required to perform a transitional goodwill impairment assessment. The Company has not yet determined the impact these standards will have on its results of operations and financial position. Goodwill amortization of $14,000 was recorded during the first quarter of fiscal 2002. An estimated $56,000 will be recorded during fiscal 2002 for the full year. NOTE 8 - PRODUCT LINE DISPOSITION On October 6, 1999, the Company sold all assets and rights related to its Biocor(TM) oxygenator and EnGUARD(TM) PHX cardioplegia systems components to LifeStream International LLC, a newly formed cardiopulmonary products company, in exchange for $7.2 million in cash and warrants. Under the terms of the agreement Minntech received $2.24 million in cash at closing. One payment of $.25 million was received when a product modification met specifications and another $.25 million was received when 510K approval by the Federal Drug Administration was received on a new product. An additional $1.25 million was received on the one year anniversary of the sale and $.28 million of inventory was purchased. The remaining amount to be collected is $1.45 million in deferred payments. In addition, LifeStream will purchase the remaining inventory balances for these product lines when the Company ceases the contract manufacturing arrangement. As of June 30, 2001 the Company had $.35 million in related inventory for these products. Page 9 <Page> NOTE 9 - MERGER AGREEMENT WITH CANTEL MEDICAL CORP. On May 30, 2001, the Company entered into a definitive merger agreement with Cantel Medical Corporation, under which Cantel will acquire the Company. Under the terms of the agreement, each share of Minntech stock will be converted into the right to receive $10.50, consisting of $6.25 in cash, and a fraction of a share of common stock of Cantel having a value of $4.25, subject to possible adjustment. For more information on the merger and the merger agreement, please refer to the joint proxy statement/prospectus of Cantel and the Company, which is included in Cantel's registration statement on Form S-4 (Reg. No. 333-64580) filed on July 30, 2001. Cantel and the Company have each called special meetings of their shareholders to approve the merger. These meetings will be held on September 6, 2001. The merger is expected to close shortly after the shareholders' meetings, if shareholder approval is received. The transaction is subject to customary closing conditions, including the approval of the shareholders of the Company and Cantel. Under the merger agreement, the Company has the right to terminate the agreement if Cantel's average closing stock price during a defined period ending shortly before the merger is below $13.24, unless Cantel elects to provide the Company's shareholders additional consideration, in cash or Cantel shares, at Cantel's option, such that the total consideration is no less than $10.00 for each Minntech share. Additional information about the proposed merger can be found in the proxy statement / prospectus, and other documents filed with the Securities and Exchange Commission, which can be accessed at www.sec.gov. On May 30, 2001, the Company's Board of Directors amended the share rights plan (described in "Note 9 - Preferred Stock" above) to exempt this transaction from its application. The Company recorded charges of approximately $.30 million in legal and consulting expenses in connection with this transaction in the first quarter of fiscal 2002. Page 10 <Page> QUARTERLY REPORT ON FORM 10-Q PART I - FINANCIAL INFORMATION ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS RESULTS OF OPERATIONS Revenue in the first quarter of fiscal 2002 increased 13.3 percent to $20.0 million, compared to $17.6 million in the same period one year ago. Dialysis product sales increased 8.0 percent to $14.9 million in the first quarter of fiscal 2002 due primarily to increases in dialyzer reprocessing product sales, with dialyzer reprocessing equipment unit growth accounting for most of the increase. Cardiosurgery sales increased by 34.8 percent to $2.8 million in the first quarter of fiscal 2002. The cardiosurgery sales increase in the quarter is due to increases in hemofilter, hemoconcentrator, and oxygenator sales. Developing businesses sales increased 30.0 percent to $2.3 million in the first quarter of fiscal 2002 due primarily to a 38.5% increase in filtration and separation products which was driven by growth in sterilant products. Product sales by group are summarized in the following table: <Table> <Caption> Quarter ended (in thousands of dollars) June 30, 2001 % of July 1, 2000 % of Total Sales Total Sales ------------------------------------------------------- Dialysis products $ 14,869 74.5% $13,771 78.2% Cardiosurgery products 2,770 13.9 2,055 11.7 Other Developing Business products 2,312 11.6 1,779 10.1 - ---------------------------------------------------------------------------------------------------- Total Company $ 19,951 100.0% $17,605 100.0% ==================================================================================================== </Table> Following is a summary of earnings/(loss) from operations before income taxes by business segment: <Table> <Caption> Quarter ended (in thousands of dollars) June 30, 2001 % of July 1, 2000 % of Segment Revenues Segment Revenues --------------------------------------------------------------------- Dialysis products $ 2,788 18.8 % $ 2,536 18.4 % Cardiosurgery products 935 33.8 206 10.0 Other Developing Businesses 744 32.2 (230) -- Corporate & Unallocated (2,865) -- (2,653) -- - ------------------------------------------------------------------------------------------------------------------ Total Company $ 1,602 8.0 % $ (141) -- ================================================================================================================== </Table> Page 11 <Page> MINNTECH CORPORATION MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED) Gross margin as a percentage of product sales increased to 39.1 percent in the first quarter of fiscal 2002 from 34.0 percent in the same quarter in the prior year. The improvement in gross margins is attributable to increased unit volume in all business segments, an improved product mix, and cost efficiencies in manufacturing and distribution. Research and development expenses in the first quarter of fiscal 2002 were $.9 million or 4.4 percent of revenues compared to $1.0 million or 5.8 percent of revenues in the prior year. The decrease in research and development spending is attributable to transitioning major development projects to later stages of completion in the current fiscal year. The Company expects that research and development spending in fiscal 2002 will range between 4.5 and 5.0 percent of revenues. Selling, general and administrative expenses for the first quarter of fiscal 2002 were $5.3 million or 26.4 percent of revenues compared to $5.1 million or 28.7 percent of revenues in the same period one year ago. Selling, general, and administrative expenses in the first quarter of fiscal 2002 include $.3 million of non-recurring expenses related to the Company's pending merger with Cantel Medical Corp. Other income of $.250 million in the first quarter of the current year is up from $52,000 in the prior year quarter due to favorable foreign exchange combined with an increase in interest income. The Company's effective tax rate for the first quarter that ended June 30, 2001 was 35.0 percent compared to effective rate of 32.0 percent for the corresponding period one year ago. The Company's effective tax rate increased in the current year primarily due to recognizing additional state income tax expense in the U.S. The Company reported net earnings of $1.2 million for the first quarter ended June 30, 2001 or 6.0 percent of revenue compared to a net loss of $.2 million in the first quarter one year ago. The increase in net earnings in the current year is primarily attributable to the improvement in gross margins from the prior year. LIQUIDITY AND CAPITAL RESOURCES Operating activities provided $.9 million of cash and cash equivalents in the first quarter ended June 30, 2001. The Company invested $.6 million in capital equipment and patents in the first quarter of fiscal 2002. At June 30, 2001 the Company had $15.8 million of cash and cash equivalents. Working capital at June 30, 2001 was $35.7 million as compared to $34.3 million as of March 31, 2001. The current ratio as of June 30, 2001 was 4.9, unchanged from March 31, 2001. The Company initiated a stock repurchase program in August 1998 and has spent $3.9 million to repurchase a total of 388,100 shares to date under the program. There have been no share repurchases since the first quarter of fiscal 2001, when the Company expended $.2 million to repurchase 24,100 shares. Page 12 <Page> MINNTECH CORPORATION MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED) The Company expects its cash balances, cash flow from operations, and line of credit to be adequate to meet its obligations and anticipated operating cash needs, including planned capital expenditures, in its core business in fiscal 2002. On May 30, 2001, the Company entered into an Agreement and Plan of Merger with Cantel Medical Corporation and a newly formed, wholly owned subsidiary of Cantel. Under the merger agreement, the Company's ability to incur additional indebtedness without Cantel's consent is substantially limited. In addition, the merger agreement precludes the Company's issuance of debt or equity securities (except in connection with option exercises) without Cantel's consent. For more information on the merger and the merger agreement, please refer to the joint proxy statement/prospectus of Cantel and the Company, which is included in Cantel's registration statement on Form S-4 (Reg. No. 333-64580) filed on July 30, 2001. Cantel and the Company have each called special meetings of their shareholders to approve the merger. These meetings will be held on September 6, 2001. The merger is expected to close shortly after the shareholders' meetings, if shareholder approval is received. EURO CONVERSION Effective January 1, 1999, the European Economic and Monetary Union created a single Eurocurrency (the euro) for its member countries. A transition period is in effect that began January 1, 1999, and goes through December 31, 2001, during which time transactions will be executed in both the euro and the member country currencies. Effective January 1, 2002, euro bank notes will be introduced and on July 1, 2002, the euro will be the sole legal tender of the European Economic and Monetary Union countries. In general, the adoption of a single currency for the participating countries is expected to result in greater transparency of pricing, making Europe a more competitive environment for businesses. However, conversion to the euro is expected to affect many financial systems and business applications. The Company switched all European business to the euro as the functional currency as of April 1, 2001. The Company's current European price list is maintained in euros. This conversion required minimal information system modifications. It is not anticipated at this time, that the euro will have a material impact on our fundamental risk management philosophy. Any costs incurred associated with the adoption of the euro were expensed as incurred, and were not material to the Company's results of operations, financial condition, or cash flows.
