ITEM 1. DESCRIPTION OF BUSINESS. (a) BUSINESS DEVELOPMENT. Northern Instruments, Inc., a predecessor to Northern Technologies International Corporation, was incorporated in the State of Minnesota on August 4, 1970. In 1976, Northern Instruments, Inc. changed its name to Northern Instruments Corporation. In 1978, Northern Instruments Corporation, a Minnesota corporation, was merged with and into Northern Instruments Corporation, a newly-formed Delaware corporation. In 1993, Northern Technologies International Corporation, a wholly-owned subsidiary, was merged into Northern Instruments Corporation. As a result of such merger, Northern Instruments Corporation changed its name to Northern Technologies International Corporation, hereafter referred to as the "Company" or "NTIC." In 1999, the Company organized Northern Instruments Corporation, LLC, an Ohio limited liability company ("NIC"); and the instruments operation of the Company was transferred into NIC. NIC is a wholly-owned subsidiary of the Company. Effective March 4, 1999, Special Control Systems, Inc., an Ohio corporation 100% owned by the Company, was merged into NIC. The operating results and assets of NIC are included in the consolidated financial statements of the Company. (b) BUSINESS OF THE COMPANY. GENERAL The Company is a developer, manufacturer and marketer of materials science based industrial packaging products and systems and electronic sensing instruments. The Company's dry corrosion inhibiting products, marketed under the name ZERUST(R) ("ZERUST"), are utilized in protective packaging serving a wide variety of companies in industries such as transportation, nuclear and fossil fuel power generation, electronics, aerospace, on-and off-road automotive equipment, agriculture and metal processing. The ZERUST product line accounted for approximately 96% of the Company's sales during its fiscal year ended August 31, 1999. The Company's electronic sensing instruments include portable oil quality analyzers for on-site evaluation of various types of oils and fluids, instruments that provide for on- and off-line measurement of fiber denier and devices, which utilize microwave technology to measure moisture and the tempo of manufacturing process in metallurgical facilities. JOINT VENTURES AND EUROPEAN HOLDING COMPANY The Company participates in an expanding number of international joint venture arrangements that provide for the manufacturing, marketing and distributing of materials science based industrial packaging products based upon the Company's technology. Both the Company and the Company's corporate joint venture in 2 Germany, Excor Korrosionsschutz - Technologien und Produkte GmbH ("Excor"), manufactures and supply the proprietary ingredients that make the finished product functional, but the actual manufacturing of the finished product itself takes place in each country in which the Company has a joint venture or similar relationship. Manufacturing the product in foreign countries lowers shipping costs and improves on-time delivery to foreign customers. The joint venture arrangements allow the Company to successfully market and sell its products in foreign countries through the marketing efforts of joint venture partners without the Company having to develop its own international sales force. The Company's joint venture partners are knowledgeable in the applicable environmental, labor, tax regulations and laws of the respective foreign countries, as well as the local customs and business practices, and have a vested interest in making each joint venture a success. All of the Company's joint ventures are owned 50% by the Company, except where the Company has invited a related third party to purchase a portion of the ownership that the Company would otherwise have purchased. Thus, for example, the Company owns 25% of the joint venture in South Korea, and Taiyo Petroleum Gas Co. Ltd., the Company's Japanese joint venture partner, also owns 25% of that entity. The Company organized NTI Asean LLC, a Nevada limited liability company, for its joint venture investments in the Asean region, which, of course, does not encompass Japan or South Korea. NTI Asean LLC is owned 50% by the Company and 50% by Taiyo Petroleum Gas Co. Ltd. The Company has established the following corporate joint ventures, in which the Company has an ownership interest either directly or indirectly through NTI Asean LLC: Date of Country Investment Japan 1987 Taiwan 1990 France 1990 Germany 1991 Sweden 1991 Singapore 1991 Brazil 1993 Austria 1994 Russia 1994 South Korea 1994 Finland 1995 Italy 1996 United Kingdom 1997 Czech-Republic 1997 Poland 1998 Indonesia 1998 Thailand 1998 In addition to the Company's investments in the corporate joint ventures listed above, the Company acquired a 50% ownership interest in a European holding company during fiscal year 1997; however, to date, this entity has been inactive. While the Company is not aware of any specific potential risk beyond its initial investment and undistributed earnings of the joint ventures, there can be no assurance that the Company will not be subject to lawsuits based on product liability claims or other claims arising out of the activities of the joint 3 ventures. To protect against such an occurrence, the Company maintains liability insurance specifically applicable to its ownership positions in the international joint venture arrangements in excess of any insurance the joint ventures may maintain. PRODUCTS The Company operates in two businesses: materials science based industrial packaging products and electronic sensing instruments. Materials science based industrial packaging products accounted for approximately 96% of the Company's sales in fiscal year 1999. MATERIALS SCIENCE BASED INDUSTRIAL PACKAGING PRODUCTS. Corrosion negatively affects products and components in the manufacturing industry. This applies to the rusting of ferrous (iron and steel) metals and the deterioration by oxidation of nonferrous (aluminum, copper, brass, etc.) metals. In combating corrosion, the traditional approach has been to apply oils and greases to protect metal parts. This approach commonly requires specialized application equipment. In addition, the oils and greases may pose unacceptable health and fire hazards and also may collect and trap dirt and debris that, in some cases, may actually initiate corrosion. For the removal of such oils and greases, chemical solvents and specialized safety equipment may be necessary that typically introduce additional health and hazardous waste disposal problems. ZERUST volatile corrosion inhibiting ("VCI") products may entirely eliminate or reduce the use of oils and greases to inhibit corrosion; for ZERUST formulations contain proprietary chemical systems that emit a nontoxic vapor that is diffused throughout an enclosure. Electron scanning instrumentation shows that the VCI-rich atmosphere causes VCI molecules to condense in a microscopic layer on all surfaces they reach. The inhibiting layer is maintained so long as the product remains within the ZERUST package. Electron scanning further shows that once the contents are removed from the ZERUST package, the VCI layer revolatilizes from the contents' surfaces within two hours, leaving a clean, dry and corrosion-free product. This mechanism of corrosion protection enables the Company's customers to package and ship metal parts so that they arrive ready for use. Furthermore, by eliminating costly greasing and degreasing processes, ZERUST VCI technology provides significant savings in labor, material and capital expenditures for equipment to apply, remove and dispose of oil and grease as compared to traditional methods of corrosion prevention. In 1980, the Company developed a means of combining ZERUST VCI systems with polyethylene and polypropylene resins, and was granted a patent on this process on September 22, 1981. Subsequently, a line of flexible packaging products in the form of low and high density polyethylene bags and shroud film, stretch, shrink, skin and bubble cushioning film, woven scrim and foam sheeting was introduced to United States industry. This gave packaging engineers an opportunity to ship and store ferrous, nonferrous and mixed multi-metal products in a clean, dry and corrosion-free condition, with an attendant overall savings in total packaging cost. The Company subsequently expanded the ZERUST product line to include a range of rigid plastic products in the form of profile and corrugated board, thermoformed dunnage trays and bins, injection and blow molded products and flat netting. The Company also has developed additives in liquid form to imbue corrugated cardboard, solid fiber and chipboard packaging materials with VCI corrosion protection properties. ELECTRONIC SENSING INSTRUMENTS. The Company's electronic sensing instruments accounted for approximately 4% of the Company's sales in fiscal year 1999. The Company's electronic sensing instruments include oil quality analyzers, fiber monitors and testers, and other instruments used primarily 4 for process and quality control of materials in hostile environments, such as steel mills. Several of the Company's electronic sensing instruments are based on the measurement of the change in dielectric properties of different liquids and fibers by means of capacitance sensors. The instrument product line, however, also includes measurement devices for materials and moisture testing based upon microwave technology. MANUFACTURING The Company produces certain proprietary materials science based industrial packaging formulations and products at its facility in Lino Lakes, Minnesota and electronic sensing instruments at facilities in Forest Lake, Minnesota and Cleveland, Ohio. The Company's materials science based industrial packaging end products include flexible and rigid packaging systems and other products that are produced to customer specification by selected contractors who are supplied with the necessary active ingredients by the Company. The Company is ISO 9001 certified with respect to its materials science based industrial packaging production. The Company believes that the process of ISO 9001 certification serves as an excellent tool for total quality management, enabling the Company to provide consistency and excellence in its products. Also, because potential customers may prefer or require manufacturers to have achieved ISO certification, such ISO certification may provide the Company with certain competitive advantages. SALES AND MARKETING OF MATERIALS SCIENCE BASED INDUSTRIAL PACKAGING PRODUCTS In the United States, the Company markets its materials science based industrial packaging products principally to industrial users by a direct sales force and through a network of distributors and sales representatives. The Company's technical service representatives work directly with the end users of the Company's products to analyze their specific needs and develop systems to meet their technical requirements. Internationally, the Company has entered into (either directly or through NTI Asean LLC) joint ventures and similar arrangements with foreign partners. Pursuant to these arrangements, the Company and/or Excor supply certain proprietary formulations to the foreign joint venture entities, which in turn provide for the international manufacture and marketing of ZERUST and others finished products. The Company receives fees for providing technical support and marketing assistance to the joint ventures in accordance with the terms of the joint venture arrangements. COMPETITION The Company is aware of other organizations that manufacture and market corrosion inhibiting packaging products, which compete with the Company's ZERUST products. The Company evaluates competing products on an ongoing basis and believes that none of the competing products on the market at this time are superior to the Company's products. The Company is aware of competitors in the "Lubri-Sensor" oil quality analyzer area; however, the Company does not have any knowledge as to the business effectiveness of such competitors and believes that the Company's products are competitive with all other products currently on the market. In the "Foodoil Sensor" oil quality analyzer area, the Company is aware of a competitor who does not provide an analysis instrument but instead provides a paper test strip. Although the Company believes that its product offers significant advantages over paper test strips, the Company believes that sales of the 5 Foodoil Sensor have historically been limited by price sensitivity rather than differences in product capabilities. Some of the Company's competitors, in both the materials science based industrial packaging area and the electronic instrument area, are established companies that may have financial and other resources greater than those of the Company. Additionally, some of these companies may have achieved significant market impact and brand recognition. The Company competes with such companies by providing high quality products and by attempting to provide the highest level of customer service, including real time direct technical support and applications engineering. SIGNIFICANT CUSTOMERS No single customer accounted for more than 10% of net sales for the fiscal year ended August 31, 1999. One customer accounted for approximately 16% and 14% of net sales for the fiscal years ended August 31, 1998 and 1997, respectively. RESEARCH AND DEVELOPMENT The Company's research and development activities are directed at the improvement of existing products, new product development and quality assurance through improved testing of the Company's products. The Company's research and development expenditures, including engineering and technical support, were $578,231, $487,456, and $432,943 in fiscal years 1999, 1998 and 1997, respectively. In 1997, the Company's joint venture in Germany, Excor Korrosionsschutz - Technologien und Produkte GmbH, established a wholly-owned subsidiary, Excor Korrosionsforschung GmbH, to conduct research into new fields of materials science based industrial packaging and the applications engineering thereof in conjunction with the Company's domestic research and development operation. Today the Company's U.S.A. research and development activities are conducted at its Minnesota headquarters, in Dresden, Germany and at various international locations staffed by independent contractors to the Company. The results of the research and development activities outside Minnesota and Germany, like the results of the Company's research and development efforts generally, invariably engender certain proprietary rights for the Company. PATENTS AND TRADEMARKS The Company is committed to the timely and continual upgrading of its product line and the introduction of new products, developed in-house or via exclusive technology licenses. The Company currently owns one United States patent, which will expire in 2000, relating to its corrosion inhibiting products. The Company believes that trade secrets and proprietary (albeit unpatented) know-how are at least as important as patent protection in establishing and maintaining a competitive advantage; and that mere patent protection without close technical support and applications engineering will not serve to keep any given supplier in the forefront of any sophisticated technology based market. The Company also has several registered trademarks in the United States and certain foreign countries. The registered trademarks in the U.S. are: the logo "NTI", the word "ZERUST", the words "THE ZERUST PEOPLE", the word "PLASTABS", the words "COR TAB" and the color "YELLOW" "for anticorrosive plastic film used for packaging metallic products, for industrial and consumer use". The Company's trademarks have a life, subject to periodic maintenance, of 10 to 20 years, which may be extended. 6 BACKLOG The Company did not have a significant order backlog as of August 31, 1999. Customers generally place orders on an "as needed" basis and expect delivery within a relatively short period of time. WORKING CAPITAL AND AVAILABILITY OF MATERIALS The Company does not carry excess quantities of raw materials or purchased parts because of widespread availability thereof from various suppliers. The Company has sufficient working capital to meet all obligations when due. EMPLOYEES As of August 31, 1999, the Company had 27 full-time direct employees in the United States, including five engaged in administration, twelve in sales and marketing, three in research and development and seven in operations. There are no unions representing the Company's employees and the Company believes that its relations with employees are good. There are no pending or, to the Company's knowledge, threatened labor or employment disputes or work interruptions. CERTAIN IMPORTANT FACTORS In addition to the influences identified above, there are several important factors that could cause the Company's actual results to differ materially from those anticipated by the Company or which are reflected in any forward-looking statements of the Company. Such factors, which may impact on the success of the Company's operations and its ability to achieve its goals, include the following: (1) The Company's ability to make investments in existing and future joint ventures to generate a positive rate of return and demonstrate a pattern of growth consistent with past and current performance; and (2) The Company's ability to continue to enter into international markets in a timely fashion; and (3) The Company's ability to maintain gross margins at a level consistent with the technological advantages of its proprietary products. ITEM 2. DESCRIPTION OF PROPERTY. The Company's primary office, production facilities and domestic research and development operations are located at 6680 North Highway 49, Lino Lakes, Minnesota 55014. The Company owns approximately 3.5 acres at this site and three buildings thereon. The main building, consisting of approximately 15,300 square feet, is used for office, production, research and development and shipping and receiving. A second building of approximately 7,200 square feet and a third building of approximately 4,800 square feet are used for warehouse space. In 1995, the Company acquired an approximately 10 acre parcel of land located in Forest Lake, Minnesota, approximately six miles from the Company's offices. On this parcel, the Company built a warehouse of approximately 18,000 square feet that was completed in November 1996. The parcel of land on which this warehouse is located is of sufficient size should the Company choose to relocate its entire facility to this location, although the Company has no current plans to do so. The Company leases approximately 750 square feet in 7 Cleveland, Ohio for $650 per month on a month-to-month basis. The Company uses this space for production of electronic sensing instruments. ITEM 3. LEGAL PROCEEDINGS. There is no material pending or threatened legal, governmental, administrative or other proceeding to which the Company is a party or of which any of its property is the subject. ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS. No matter was submitted to a vote of security holders during the fourth quarter of the fiscal year covered by this Report. 8 PART II ITEM 5. MARKET FOR THE REGISTRANT'S COMMON STOCK AND RELATED STOCKHOLDER MATTERS. Effective September 10, 1993, the Company's Common Stock commenced trading on, and it continues to trade on, the American Stock Exchange under the symbol NTI. COMMON STOCK ------------ HIGH LOW ---- --- 1999: Fourth fiscal quarter............. $ 8 3/8 $ 5 11/16 Third fiscal quarter.............. 6 7/8 5 1/2 Second fiscal quarter............. 7 1/4 5 3/8 First fiscal quarter.............. 7 5 1998: Fourth fiscal quarter............. $ 8 $ 6 7/16 Third fiscal quarter.............. 9 7/8 7 3/8 Second fiscal quarter............. 11 1/4 8 1/2 First fiscal quarter.............. 12 3/4 9 1/4 The Company declared Common Stock cash dividends of $.15 per share to shareholders of record on December 1, 1997; $.15 per share to shareholders of record on December 4, 1998; and $0.16 per share to shareholders of record on December 3, 1999. The Company's Board of Directors will continue to evaluate the payment of dividends based on the Company's net income and operating cash requirements. As of August 31, 1999, the Company's Common Stock was held by approximately 500 shareholders of record. ITEM 6. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS. RESULTS OF OPERATIONS FISCAL YEAR 1999 COMPARED TO FISCAL YEAR 1998 NORTHERN TECHNOLOGIES INTERNATIONAL CORPORATION NET SALES AND COST OF SALES. The Company's net sales originating in the United States of $9,870,531 in fiscal year 1999; a decrease of $206,963 or 2.1% from net sales of $10,077,494 in fiscal year 1998. The decrease in net sales is due primarily to a decrease in the volume of materials science based industrial packaging products sold to the Company's international corporate joint ventures partially 9 offset by an increase in the volume of such products sold to new and existing customers in North America. During fiscal year 1999, certain of the corporate joint ventures purchased active formulations previously sourced from the Company from a corporate joint venture of the Company. The Company expects this trend to continue in the future. No single customer accounted for more than 10% of sales in fiscal year 1999, whereas, in fiscal year 1998 sales to one customer accounted for 16% of total sales. The decrease in sales to a single customer is a result of a major industrial customer changing logistic firms during fiscal year 1999. The new logistic firm of that industrial customer has, however, itself become a customer of the Company, and the Company expects sales to this firm may exceed 10% of net sales in the future. The cost of sales decreased as a percentage of sales to 47.9% in fiscal year 1999 from 49.1% in fiscal year 1998. The variation in the cost of sales percentage reflects changes in product mix. The Company anticipates that its annual percentage of cost of sales for fiscal year 2000 will not vary significantly under its current pricing structure. SELLING EXPENSES. The Company's selling expenses increased by $230,249 or 18.3% to $1,490,857 in fiscal year 1999 from $1,260,608 in fiscal year 1998. The increase in selling expenses in fiscal year 1999 was primarily related to increases in salaries and related expenses, sales promotion, and travel. As a percentage of sales these costs increased to 15.1% in fiscal year 1999 from 12.5% in fiscal year 1998 due to the decreased level of net sales and the overall increase in selling expenses in fiscal year 1999. GENERAL AND ADMINISTRATIVE EXPENSES. The Company's general and administrative expenses increased by $218,155 or 15.1% to $1,664,936 in fiscal year 1999 from $1,446,781 in fiscal year 1998. The increase in general and administrative expenses in fiscal year 1999 was primarily due to increases in salaries and related expenses, various professional fees, and building maintenance. As a percentage of sales these costs increased to 16.9% in fiscal year 1999 from 14.4% in fiscal year 1998 due to the decreased level of net sales and the overall increase in general and administrative expenses in fiscal year 1999. RESEARCH, ENGINEERING, AND TECHNICAL SUPPORT EXPENSES. The Company's research, engineering, and technical support expenses increased by $90,775 or 18.6% to $578,231 in fiscal year 1999 from $487,456 in fiscal year 1998. The increase in research, engineering and technical support expenses in fiscal year 1999 was primarily due to the increase of research and development activities conducted at various international locations by independent contractors to the Company. The results of the Company's international research and development activities, as the results of the Company's research and development efforts, invariably engender certain proprietary rights thereto to the Company. As a percentage of sales these costs increased to 5.9% in fiscal year 1999 from 4.8% in fiscal year 1998 due to the decreased level of net sales and the increased research, engineering, and technical support activities in fiscal year 1999. The Company anticipates that its fiscal year 2000 research, engineering, and technical support expenses will surpass expenses incurred in fiscal year 1999. OPERATIONS OF INTERNATIONAL JOINT VENTURES CORPORATE JOINT VENTURE AND EUROPEAN HOLDING COMPANY. The Company continues its business program of establishing corporate joint venture arrangements in international markets. The Company and/or an existing corporate joint venture manufactures and supplies patented and/or proprietary ingredients, which make the finished 10 products functional and enable manufacturing of the finished products to take place in the foreign countries. The corporate joint ventures then market the finished products in their respective territories, and the corporate joint ventures' profits are shared by the respective corporate joint venture shareholders in accordance with share ownership. The Company received fees for technical and other support to the corporate joint ventures based on the revenues of the individual corporate joint ventures. The Company recognized fees for such support in the amounts of $2,459,697 and $1,868,938 for fiscal years 1999 and 1998, respectively. The increase in fees for technical and other support to corporate joint ventures was primarily due to the greater efficacy of the Company's service to its corporate joint ventures, which provided for increased sales volume at certain of the Company's corporate joint ventures located in the Pacific Rim and Europe. Sales of the corporate joint ventures in fiscal year 1999 increased $2,444,772 or 12.5% to $22,022,767. The Company incurred direct expenses related to corporate joint ventures and the European holding company of $741,703 and $566,051 in fiscal years 1999 and 1998, respectively. These expenses consisted primarily of technical and marketing services to existing joint ventures as well as legal fees regarding the development of new joint ventures, travel and meetings; but do not include a share of research and development expenses or of selling expenses incurred by the Company, including for participation in the international trade fairs and symposia. The Company anticipates that expenses relating to corporate joint ventures will continue to increase in the future due to the Company providing ongoing technical, marketing and other support to its joint ventures, and to the development of new corporate joint ventures. The Company and NTI Asean LLC ("NTI Asean") anticipate that in the future they will enter into joint ventures in other foreign countries. The Company maintains a 50% ownership interest in NTI Asean, with the remaining 50% ownership interest owned by Taiyo Petroleum Gas Co. Ltd., which also owns the other 50% ownership interest in the Company's corporate joint venture located in Japan. The Company also has an investment in a European holding company, which is currently inactive. The Company's investments in corporate joint ventures and the European holding company are accounted for using the equity method and resulted in income to the Company of $368,711 and $549,875 for fiscal years 1999 and 1998, respectively. The decrease in equity in income of corporate joint ventures and the European holding company was primarily due to high inflation in South America. Net income of the corporate joint ventures in fiscal year 1999 of $1,038,785 represents a 14.6% decrease from fiscal year 1998, due to higher operating expenses and in some measure to currency fluctuations. INCOME TAXES INCOME TAXES. The Company's effective income tax rates were 29.7% and 33.5% for fiscal years 1999 and 1998, respectively. The decrease in the effective income tax rate in fiscal year 1999 is due to the utilization of a net operating loss carry forward that became available in fiscal year 1999. The effective income tax rate is also lower than the statutory rate due to equity in income of corporate joint ventures and the European holding company being recognized based on after tax earnings of these entities. To the extent the corporate joint ventures' and the foreign company's undistributed earnings were distributed to the Company during fiscal years 1999 and 1998, it did not result in material additional income tax liability after the application of foreign tax credits. 11 FISCAL YEAR 1998 COMPARED TO FISCAL YEAR 1997 NORTHERN TECHNOLOGIES INTERNATIONAL CORPORATION NET SALES AND COST OF SALES. The Company's net sales originating in the United States of $10,077,494 in fiscal year 1998 increased by $1,348,176 or 15.4% from net sales of $8,729,318 in fiscal year 1997. The increase in net sales is primarily due to an increase in the volume of materials science based industrial packaging products sold to new and existing customers. Fiscal year 1998 sales to an existing customer increased to 16% of total sales in fiscal year 1998 from 14% of total sales in fiscal year 1997. The cost of sales increased as a percentage of sales to 49.1% in fiscal year 1998 from 47.4% in fiscal year 1997. The variation in the cost of sales percentage reflects changes in product mix. SELLING EXPENSES. The Company's selling expenses increased by $168,328 or 15.4% to $1,260,608 in fiscal year 1998 from $1,092,280 in fiscal year 1997. The increase in selling expenses in fiscal year 1998 was primarily related to increases in salaries and related expenses and travel. As a percentage of sales these costs were 12.5% in fiscal years 1998 and 1997. GENERAL AND ADMINISTRATIVE EXPENSES. The Company's general and administrative expenses decreased by $439,235 or 23.3% to $1,446,781 in fiscal year 1998 from $1,886,016 in fiscal year 1997. The decrease in general and administrative expenses in fiscal year 1998 was primarily due to decreases in personnel costs and related expenses, various professional fees and real estate and other expenses associated with the Company's expanded warehouse facility, which was completed in fiscal year 1997. As a percentage of sales, these costs decreased to 14.4% in fiscal year 1998 from 21.6% in fiscal year 1997 due to the increased level of net sales in fiscal year 1998 and the decrease in fiscal year 1998 in general and administrative expenses. RESEARCH, ENGINEERING, AND TECHNICAL SUPPORT EXPENSES. The Company's research, engineering, and technical support expenses increased by $54,513 or 12.6% to $487,456 in fiscal year 1998 from $432,943 in fiscal year 1997. The increase in research, engineering and technical support expenses in fiscal year 1998 was primarily due to increases in personnel costs and related expenses and increases in expenses for research, engineering and technical support supplies. As a percentage of sales these costs decreased to 4.8% in fiscal year 1998 from 5.0% in fiscal year 1997 due to the increased level of net sales in fiscal year 1998. OPERATIONS OF INTERNATIONAL JOINT VENTURES CORPORATE JOINT VENTURE AND EUROPEAN HOLDING COMPANY. The Company's investments in corporate joint ventures and the European holding company are accounted for using the equity method and resulted in income to the Company of $549,875 and $712,244 for fiscal years 1998 and 1997, respectively. In addition, the Company received fees for technical and other support to the corporate joint ventures based on the revenues of the individual corporate joint ventures. The Company recognized fees for such assistance of $1,868,938 and $2,213,228 for fiscal years 1998 and 1997, respectively. The decrease in equity in income of corporate joint ventures and the European holding company, and fees for technical and other support to corporate joint ventures was primarily due to the strengthening of the U.S. dollar when compared to the local currencies of the Company's corporate joint ventures, and decreased sales volume at certain of the Company's corporate joint ventures located in the Pacific Rim. Sales of the 12 corporate joint ventures in fiscal year 1998 decreased $180,091 or 0.9% to $19,577,995. Net income of the corporate joint ventures in fiscal year 1998 of $1,216,111 represents an 18.8% decrease from fiscal year 1997. The Company recognized expenses related to corporate joint ventures and the European holding company of $566,051 and $457,263 in fiscal years 1998 and 1997, respectively. The expenses consist primarily of marketing, technical and other services to existing joint ventures, as well as legal fees regarding the development of new joint ventures, travel, and meetings. INCOME TAXES INCOME TAXES. The Company's effective income tax rates were 33.5% and 31.5% for fiscal years 1998 and 1997, respectively. The effective income tax rate was lower than the statutory rate primarily due to equity in income of corporate joint ventures and the European holding company being recognized based on after tax earnings of these entities. To the extent the corporate joint ventures' and the foreign company's undistributed earnings were distributed to the Company during fiscal years 1998 and 1997, it did not result in material additional income tax liability after the application of foreign tax credits. LIQUIDITY AND CAPITAL RESOURCES At August 31, 1999, the Company's working capital was $5,471,523 including $2,750,209 in cash and cash equivalents, with a current ratio of 9.1:1. At August 31, 1998, the Company's working capital was $4,567,334, including $2,200,490 in cash and cash equivalents, with a current ratio of 14.2:1. Net cash provided from operations has been sufficient to meet liquidity requirements, capital expenditures, research and development cost, and expansion of operations of the Company's joint ventures. Cash flow from operations totaled $1,983,425, $2,048,207, and $1,753,483 for the fiscal years 1999, 1998, and 1997, respectively. The net cash flow from operations for fiscal years 1999, 1998, and 1997 resulted principally from net income and joint venture dividends offset by a non-cash component of net income identified as equity in income of corporate joint ventures and European holding company. Net cash used in investing activities totaled $641,317, $91,682 and $985,457 for fiscal years 1999, 1998, and 1997, respectively. The primary uses of cash in fiscal years 1999 and 1998 were investments in corporate joint ventures and additions to property. The primary uses of cash in fiscal year 1997 were investments in corporate joint ventures and European holding company, trading investments, property development and the issuance of a loan to a joint venture partner pursuant to a note. In fiscal years 1999 and 1998, the Company's expenditures of cash for investing activities were offset by repayment of the corporate joint venture note and proceeds from the sale of trading investments, respectively. Net cash used in financing activities was $792,389, $3,701,602, and $529,979 for fiscal years 1999, 1998, and 1997, respectively. The primary uses of cash in financing activities resulted from the payment of dividends and the repurchase of common stock. The primary source of cash provided by financing activities was proceeds from the exercise of stock options. The Company expects to meet future liquidity requirements with its existing cash and cash equivalents and cash flows from future operating earnings and distributions of earnings and technical assistance fees from the corporate joint venture investments. 13 The Company has no long-term debt and no material lease commitments as at August 31, 1999. The Company has no postretirement benefit plan and does not anticipate establishing any postretirement benefit program. Inflation in the U.S. historically has had little effect on the Company. IMPACT OF YEAR 2000 Computer programs have historically been written to abbreviate dates by using two digits instead of four digits to identify a particular year. The so-called "year 2000 problem" or "millennium bug" is the inability of computer software or hardware (collectively, "Systems") to recognize or properly process dates ending in "00" and dates after the year 2000. Significant attention is being focused as the year 2000 approaches on updating or replacing such Systems in order to avoid System failures, miscalculations or business interruptions that might otherwise result. The Company believes it has taken the steps necessary to insure that this potential problem does not adversely affect the Company's operating results in the future, and continues to assess the impact of the year 2000 problem on the Company. The Company has taken, and will continue to take, actions intended to minimize the impact of the year 2000 problem and maximize the Company's state of readiness for the year 2000. However, it is impossible to eliminate year 2000 risks entirely. Unfortunately, there is no single test that can be used to conclusively determine whether Systems are year 2000 compliant. To the contrary, the technology community identifies additional potential year 2000 risks regularly. Also impeding year 2000 testing is the high degree of integration between various Systems and the difficulty in conducting full-scale live testing. Consequently, inter-related Systems believed secure in a test environment could conceivably fail when operating together under real-time workloads. The Company's state of readiness for the year 2000, the Company's estimated costs associates with year 2000 issues, the risks the Company faces associated with year 2000 issues and the Company's year 2000 contingency plans are summarized below. STATE OF READINESS. All major internal information technology ("IT") systems have been replaced. Year 2000 issues were addressed when selecting and implementing these new systems, and the Company believes they are year 2000 compliant. The Company has also reviewed its major non-IT systems, including hardware, software, phone and security systems, and the Company believes they are year 2000 compliant. The Company anticipates continuing to invest in IT and non-IT technology to accommodate the Company's future growth, and the Company expects these investments and upgrades to be year 2000 compliant. The Company has concluded its on going testing program as regards to the Company's year 2000 compliance. While such testing has to date indicated the Company's IT and non - IT systems are year 2000 compliant only the systems in operation subsequent to January 1, 2000 will confirm year 2000 compliance and what, if any effect, the consequences of any year 2000 failures might have on the 14 Company. The Company has completed a review of the Company international joint ventures as to year 2000 readiness with all reporting their being year 2000 compliant. COSTS ASSOCIATED WITH YEAR 2000 ISSUES. Since unanticipated expenses may arise relating to Year 2000 issues, the Company is unable to quantify the total expected costs associated with year 2000 issues. The Company believes that these costs will not have a material adverse effect on the Company's business, financial condition, results of operations and cash flows. The total amount the Company has expended on year 2000 issues through August 31, 1999 was approximately $50,000. The Company anticipates that future costs associated with year 2000 issues will be financed with cash flows from operations. RISKS ASSOCIATED WITH YEAR 2000 ISSUES. The Company is dependent on computer processing in its business activities and the year 2000 problem creates the risk of unforeseen problems in the Company's Systems and the Systems of third parties with whom the Company does business. The failure of the Company's Systems and/or third parties' Systems could have a material adverse effect on the Company's results of operations, liquidity, and financial condition. Due to the general uncertainty inherent in the year 2000 problem, resulting in part from the uncertainty of the year 2000 readiness of third-party suppliers and customers, the Company is unable to determine at this time whether the consequences of year 2000 failures will have a material impact on the Company's results of operations, liquidity, or financial condition. The Company believes that it may need to temporarily reduce its operations if third party suppliers are not year 2000 compliant. The Company is also unable at this time to determine what the reasonably likely worst case year 2000 scenario is for the Company. CONTINGENCY PLANS. The Company has, to the extent practicable, a business interruption contingency plan to address internal and external issues specific to year 2000 problems. However, due to the widespread nature of possible year 2000 problems as regards third parties, the contingency plan process is ongoing and may require modifications as the Company obtains additional information as to the status of third party year 2000 readiness. EURO CURRENCY ISSUE On January 1, 1999, eleven of the fifteen member countries of the European Union established fixed conversion rates between their respective existing currencies and the Euro and to adopt the Euro as their common legal currency on that date (the "Euro Conversion"). Following the Euro Conversion, however, the previously existing currencies of the participating countries are scheduled to remain legal tender in the participating countries between January 1, 1999 and January 2002. During this transition period, public and private parties may pay for goods and services using either the Euro or the previously existing currencies. Beginning January 1, 2002, the participating countries will issue new Euro-denominated bills and coins for use in cash transactions. No later than July 1, 2002, the participating countries will withdraw all bills and coins denominated in the previously existing currencies making Euro Conversion complete. The Company, the corporate joint ventures and the foreign company have been evaluating the potential impact the Euro Conversion and the Euro currency may have on their results of operations, 15 liquidity or financial condition. The Company has determined that expected costs for compliance will not be material to its results of operations, liquidity, financial condition or capital expenditures. Significant noncompliance by the Company's corporate joint ventures, and their customers or suppliers could adversely impact the Company's results of operations, liquidity or financial condition. Accordingly, until the Company completes its assessment of the Euro Conversion impact, there can be no assurance that the Euro Conversion will not have a material impact on the overall business operations of the Company. RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS In June 1998, the Financial Accounting Standards Board ("FASB") issued Statement of Financial Accounting Standards ("SFAS") No. 133, "Accounting for Derivative Instruments and Hedging Activities." SFAS No. 133 requires companies to record derivatives on the balance sheet as assets and liabilities, measured at fair value. Gains or losses resulting from changes in the values of those derivatives would be accounted for depending on the use of the derivative and whether it qualifies for hedge accounting. In July 1999, the FASB issued SFAS No. 137 delaying the effective date of SFAS No. 133 for one year to fiscal years beginning after June 15, 2000, with earlier adoption encouraged. The Company has not yet determined the effects SFAS No. 133 will have on its financial position or the results of its operations. 16 ITEM 7. FINANCIAL STATEMENTS.

17 INDEPENDENT AUDITORS' REPORT To the Stockholders and Board of Directors Northern Technologies International Corporation Lino Lakes, Minnesota We have audited the accompanying consolidated balance sheets of Northern Technologies International Corporation and Subsidiary (the Company) as of August 31, 1999 and 1998 and the related consolidated statements of income, stockholders' equity, and cash flows for each of the three years in the period ended August 31, 1999.

NATURE OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES BUSINESS OPERATIONS - Northern Technologies International Corporation and Subsidiary (the Company) is engaged in the development, manufacture, and marketing of proprietary materials science based industrial products and electronic sensing instruments. CONSOLIDATION - The consolidated financial statements include the accounts of Northern Technologies International Corporation and its subsidiary. All significant intercompany transactions have been eliminated. CASH EQUIVALENTS - The Company considers investments with an original maturity of three months or less to be cash equivalents. INVENTORIES - Inventories are recorded at the lower of cost (first-in, first-out basis) or market. PROPERTY AND DEPRECIATION - Property and equipment are stated at cost. Depreciation is computed using the straight-line method at rates based on the estimated service lives of the various assets as follows: Buildings and improvements 5-20 years Machinery and equipment 2-10 years INVESTMENTS IN CORPORATE JOINT VENTURES - Investments in corporate joint ventures are accounted for using the equity method. Intercompany profits on inventories held by the corporate joint ventures which were purchased from the Company have been eliminated based on the Company's ownership percentage in each corporate joint venture. INVESTMENT IN EUROPEAN HOLDING COMPANY - Investment in European holding company is accounted for using the equity method. RECOVERABILITY OF LONG-LIVED ASSETS - The Company reviews its long-lived assets whenever events or changes in circumstances indicate the carrying amount of the assets may not be recoverable. The Company determines potential impairment by comparing the carrying value of the assets with expected net cash flows expected to be provided by operating activities of the business or related products. Should the sum of the expected future net cash flows be less than the carrying value, the Company would determine whether an impairment loss should be recognized. An impairment loss would be measured by comparing the amount by which the carrying value exceeds the fair value of the asset based on market value that is based on the discounted cash flows expected to be generated by the asset. As of August 31, 1999, the Company did not consider any of its assets impaired, except for $50,941 relating to the Company's investment in a corporate joint venture. INCOME TAXES - The Company utilizes the liability method of accounting for income taxes as set forth in Statement of Financial Accounting Standards (SFAS) No. 109, ACCOUNTING FOR INCOME 23 TAXES. SFAS No. 109 requires an asset and liability approach to financial accounting and reporting for income taxes. Deferred income tax assets and liabilities are computed annually for differences between the financial statement and tax basis of assets and liabilities that will result in taxable or deductible amounts in the future based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. Income tax expense is the tax payable or refundable for the period plus or minus the change during the period in deferred tax assets and liabilities. FOREIGN CURRENCY TRANSLATION - The functional currency of the corporate joint ventures and the foreign company is the applicable local currency. The translation of the applicable foreign currencies into U.S. dollars is performed for balance sheet accounts using current exchange rates in effect at the balance sheet date and for revenue and expense accounts using an average monthly exchange rate. Translation gains or losses are reported as an element of other comprehensive income (loss). REVENUE RECOGNITION - Revenue is recognized when products are shipped. A portion of the gross profit on products shipped to the Company's corporate joint ventures is deferred until such products are sold by the corporate joint ventures. RESEARCH AND DEVELOPMENT - Research and development expenditures are expensed as incurred. Total research and development expenses were $578,231, $487,456, and $432,943 for the years ended August 31, 1999, 1998, and 1997, respectively. FEES FOR TECHNICAL AND OTHER SUPPORT TO CORPORATE JOINT VENTURES - Fees for technical and other support to corporate joint ventures are recognized at the time the service is provided. STOCK-BASED COMPENSATION - The Company has adopted SFAS No. 123, ACCOUNTING FOR STOCK-BASED COMPENSATION. This statement defines a fair value based method of accounting for an employee stock option or similar equity instrument and encourages all entities to adopt that method of accounting for all of their employee stock compensation plans. However, the statement also allows an entity to continue to measure compensation cost for those plans using the intrinsic value based method of accounting prescribed by Accounting Principles Board (APB) Opinion No. 25, ACCOUNTING FOR STOCK ISSUED TO EMPLOYEES. Under the fair value based method, compensation cost is measured at the grant date based on the value of the award and is recognized over the service period, which is usually the vesting period. Under the intrinsic value based method, compensation cost is the excess, if any, of the quoted market price of the stock at the grant date or other measurement date over the amount an employee must pay to acquire the stock. The Company accounts for stock options grants and awards to employees in accordance with APB Opinion No. 25 and related interpretations. NET INCOME PER SHARE - Basic net income per share is computed by dividing net income by the weighted average number of common shares outstanding. Diluted net income per share assumes the exercise of stock options using the treasury stock method, if dilutive. Diluted net income per share is computed by dividing net income by the weighted average common and common equivalent shares outstanding. For the years ended August 31, 1999, 1998, and 1997, the assumed exercise of stock options increased the weighted average common and common equivalent shares outstanding by 41,976, 73,313, and 68,898 shares, respectively. Options to purchase 29,041, 11,575, and 0 shares of common stock as of August 31, 1999, 1998, and 1997, respectively, were not included in the computations of diluted net income per share because the options' exercise 24 prices were greater than the average market price of the Company's common stock during the respective periods. USE OF ESTIMATES - The preparation of the financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. FAIR VALUE DISCLOSURE OF FINANCIAL INSTRUMENTS - Cash and cash equivalents, receivables, and current liabilities are carried at amounts which reasonably approximate their fair value due to their short-term nature. COMPREHENSIVE INCOME - On September 1, 1998, the Company retroactively adopted SFAS No. 130, REPORTING COMPREHENSIVE INCOME, which establishes standards for reporting and display of comprehensive income and its components, such as foreign currency translation adjustments, in a full set of general-purpose financial statements. Comprehensive income includes all changes in stockholders' equity except those resulting from investments by and distributions to owners. NEW ACCOUNTING STANDARD - In June 1998, the Financial Accounting Standards Board (FASB) issued SFAS No. 133, ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES. SFAS No. 133 requires companies to record derivatives on the balance sheet as assets and liabilities, measured at fair value. Gains or losses resulting from changes in the values of those derivatives would be accounted for depending on the use of the derivative and whether it qualifies for hedge accounting. In July 1999, FASB issued SFAS No. 137, delaying the effective date of SFAS No. 133 for one year to fiscal years beginning after June 15, 2000, with earlier adoption encouraged. The Company has not yet determined the effects SFAS No. 133 will have on its financial position or the results of its operations. RECLASSIFICATIONS - Certain reclassifications have been made to the 1998 and 1997 financial statements to conform to the presentation used in the 1999 financial statements. The reclassifications had no effect on stockholders' equity or net income as previously reported. 2. INVENTORIES Inventories at August 31 consist of the following: 1999 1998 Production materials $ 218,701 $ 163,177 Work-in-process 24,753 32,334 Finished goods 770,071 774,009 ------------ ------------- $ 1,013,525 $ 969,520 ============ ============= 25 3. PROPERTY AND EQUIPMENT Property and equipment at August 31 consist of the following: 1999 1998 Land $ 246,097 $ 246,097 Buildings and improvements 1,100,757 1,077,670 Machinery and equipment 964,152 674,002 ------------ ------------- 2,311,006 1,997,769 Less accumulated depreciation 1,195,777 1,042,759 ------------ ------------- $ 1,115,229 $ 955,010 ============ ============= 4. INVESTMENTS IN CORPORATE JOINT VENTURES AND EUROPEAN HOLDING COMPANY JOINT VENTURES - The Company participates in various corporate joint ventures in countries outside the United States and in similar noncontractual arrangements in various other countries. All joint ventures are owned 50% by the Company except where the Company has allowed a related third party to purchase from a joint venture a portion of the ownership that the Company would otherwise have purchased. A related third party owns 25% of the joint venture in South Korea. The joint ventures provide for the manufacturing, marketing, and distributing of material science based industrial products. The Company also has a 50% ownership interest in a limited liability company for its joint venture investments in the Asean region. A related party owns the remaining 50% ownership interest in this company. The Company has established corporate joint ventures, which the Company has an ownership interest in either directly or indirectly, as follows: Date of Country Investment Japan 1987 Taiwan 1990 France 1990 Germany 1991 Sweden 1991 Singapore 1991 Brazil 1993 Austria 1994 Russia 1994 South Korea 1994 Finland 1995 Italy 1996 United Kingdom 1997 Czech Republic 1997 Indonesia 1998 Poland 1998 Thailand 1998 26 Fees earned from the corporate joint ventures under licenses and technical and other support agreements were $2,459,697, $1,868,938, and $2,213,228 for the years ended August 31, 1999, 1998, and 1997, respectively. The Company incurred expenses associated with corporate joint ventures of $741,703, $566,051, and $457,263 for the years ended August 31, 1999, 1998, and 1997, respectively. These expenses consist primarily of legal fees regarding the development of new joint ventures, travel, and technical services regarding existing joint ventures. Summarized financial information from the audited and unaudited financial statements of joint ventures carried on the equity basis is as follows:

During 1999, the Company purchased the remaining 50% ownership interests of two corporate joint ventures the Company did not previously own for $452,152. The Company has not consolidated the accounts of the two corporate joint ventures in its financial statements due to the Company's intention of reducing its ownership percentage in both entities to 50% or less in fiscal 2000. EUROPEAN HOLDING COMPANY - During 1997, the Company invested $254,639 for a 50% ownership interest in a European holding company. To date, the entity has been inactive and its assets as of August 31, 1999 and 1998 consist primarily of cash and cash equivalents. The Company's share of equity in loss of European holding company was $614 and $6,769 for the years ended August 31, 1999 and 1998, respectively. 5. STOCKHOLDERS' EQUITY During 1999, 1998, and 1997, the Company acquired and retired 80,989, 374,765, and 9,000 shares of common stock for $514,122, $3,146,668, and $53,100, respectively. 27 During 1999, the Company issued 3,200 shares of common stock in return for services provided. The value of the common stock issued, $22,050, was determined based on the market value of the Company's common stock. During 1997, certain employees received 3,000 shares of common stock, in return for services provided and expensed in 1996. The value of the common stock issued, $15,375 in 1997, was determined based on the market value of the Company's common stock. A note receivable of $129,807 (including accrued interest of $4,432) resulting from the exercise of warrants has been shown as a reduction of stockholders' equity. The note receivable bears interest at a rate of 11% and is due on demand. The increase in accrued interest receivable on the outstanding note receivable as of August 31, 1999 and 1998 has been fully reserved for, due to the uncertainty as to when the interest would be paid. During 1994, the Company's Board of Directors and shareholders approved a stock option plan (the Plan) providing for the granting of options to purchase 250,000 shares of common stock. Under the Plan, incentive stock options and nonqualified stock options may be granted to directors, officers, nonofficer employees, and others. The options have a term of five years and become exercisable ratably over a three- or four-year period beginning on the first annual anniversary date of the grant. Options are granted at prices equal to the market value of the stock on the date of grant. A summary of the status of the Company's stock options for the years ended August 31 is as follows:

The following table summarizes information about stock options outstanding at August 31, 1999:

28 If compensation cost for the Company's Plan had been determined based on the fair value at the grant date for awards in the years ended August 31, consistent with the provisions of SFAS No. 123, the Company's net income would have changed to the pro forma amounts indicated below:

The fair value of each option grant is estimated on the grant date using the Black-Sholes option-pricing model with the following assumptions and results for the grants:

6. SEGMENT INFORMATION The Company is engaged in the development, manufacture, and marketing of proprietary material science based industrial products and electronic sensing instruments. Further disclosure regarding the two businesses is not presented, as management uses the consolidated information to allocate resources and evaluate performance. Sales by geographic location as a percentage of total sales were as follows:

No single customer accounted for more than 10% of net sales for the year ended August 31, 1999. One customer accounted for approximately 16% and 14% of net sales for the years ended August 31, 1998 and 1997, respectively. 29 7. RETIREMENT PLAN The Company has a 401(k) employee savings plan. Employees who meet certain age and service requirements may elect to contribute up to 15% of their salaries. The Company contributes the lesser of 50% of the participant's contributions or 3 1/2% of the employee's salary. The Company recognized expense for the savings plan of $39,000, $40,000, and $36,000 for the years ended August 31, 1999, 1998, and 1997, respectively. 8. RELATED PARTY TRANSACTIONS The Company paid reimbursement for travel and related expenses of $414,500, $458,000, and $382,000 for the years ended August 31, 1999, 1998, and 1997, respectively, to a financial and management consulting firm of which the Company's Co-Chief Executive Officer and Chairman of the Board and another Executive Officer are officers and directors. 9. INCOME TAXES The provisions for income taxes for the years ended August 31 consist of the following:

Reconciliations of the expected federal income tax at the statutory rate with the provisions for income taxes for the years ended August 31 are as follows:

The Company has not recognized a deferred tax liability relating to investments in foreign corporate joint ventures and European holding company that are essentially permanent in duration of $840,000 and $740,000 at August 31, 1999 and 1998, respectively. If some or all of the undistributed earnings of the foreign corporate joint ventures and European holding company are remitted to the Company in the future, income taxes, if any, after the application of foreign tax credits will be provided at that time. 30 The tax effect of the temporary differences and tax carryforwards comprising the net deferred taxes shown on the balance sheets at August 31 are as follows:

10. CONTINGENCIES The Company is involved in various legal actions arising in the normal course of business. Management is of the opinion that any judgment or settlement resulting from pending or threatened litigation would not have a material adverse effect on the financial position or results of operations of the Company. 11. STATEMENTS OF CASH FLOWS Supplemental disclosures of cash flow information for the years ended August 31 consist of:

12. SUBSEQUENT EVENT On November 19, 1999, the Company's Board of Directors declared a $.16 per share dividend on all outstanding shares of the Company's common stock to be distributed on December 17, 1999 to holders of record on December 3, 1999. 31 13. QUARTERLY INFORMATION (UNAUDITED)

During the fourth quarters of 1999 and 1998, the Company adjusted the carrying value of inventory as a result of a complete annual physical count and valuation. This annual counting and pricing was more comprehensive than that which had been conducted on an interim basis. As a result, the Company decreased cost of sales by approximately $50,000 in the fourth quarters of 1999 and 1998, respectively. It is not practicable to determine the periods of the fiscal year to which these adjustments relate. 32 ITEM 8. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE.

Non-employee directors who are elected or appointed to the Board following the first day of the Company's fiscal year receive pro-rata portion of 2,000 shares of Common Stock calculated by dividing the number of months remaining in the fiscal year at the time of election or appointment divided by twelve.

Subsequently, Mr. Lynch returned his September 1, 1999 Director Option to purchase 2,000 shares to the Option Plan. All of such Director Options granted vest in equal one-third installments over a three-year period. 36 B.

On October 1, 1976, the Company entered into a Manufacturer's Representative Agreement with The Saxxon Organization, Incorporated (the "Agreement"). The Agreement has no expiration date and may be terminated by either party upon 60 days written notice. Effective January 9, 1980, the Agreement was assigned to Inter Alia Holding Company, a financial and management consulting firm of which Philip M. Lynch, the Chairman of the Board of Directors of the Company, is an officer and director. Under the Agreement, Inter Alia Holding Company (or the "Representative") is entitled to commissions from the Company on the net proceeds of sales of the Company's product generated by Inter Alia Holding Company. The Representative acts as an independent manufacturer's representative of the Company. It has a non-exclusive worldwide right to offer for sale and solicit orders for the Company's products in accordance with prices determined by the Company. The Representative is responsible for all of its own operating expenses with no entitlement for reimbursement from the Company for this activity. The Representative has not effected any sales within the United States. The Representative has developed sales outside the United States, which resulted in commissions of approximately $45,484, $51,754, and $42,582 for the fiscal years ended August 31, 1999, 1998 and 1997, respectively. In light of the Company's own domestic sales effort and its distributor network within the United States, the Company does not anticipate the Representative developing any sales within the United States. Additionally, the Company's expanding international joint venture program may also limit opportunities abroad for the Representative. Thus, the Company does not anticipate that the Representative will develop any significant sales volume for the Company. On August 31, 1984, Inter Alia Holding Company purchased 119,083 shares of the Common Stock and paid therefore by signing a promissory note. The promissory note (the "Note") has a face value of $125,375 and bears interest at 11% per year. The Note was originally due on December 31, 1992 and is currently due on demand. The outstanding balance of the Note, including accrued interest of $119,335, was $244,710 at August 31, 1999. The Company paid reimbursement for travel and related Company expenses of $419,500, $458,000 and $382,000 for the year ended August 31, 1999, 1998 and 1997, respectively, to Inter Alia Holding Company of which the Company's Co-Chief Executive Officer and Chairman of the Board is and officer and director. Mr. G. Patrick Lynch, Vice President of Strategic Planning, Secretary and Member of the Executive Committee of the Company is also an officer and director of Inter Alia Holding Company. Mr. Gerhard Hahn, a director of the Company, is a shareholder and General Manager of Knuppel KG. Knuppel KG is a 50% partner with the Company in a joint venture in Germany. The German joint venture entity has granted a loan of 750,000 DM to Knuppel KG. The loan is secured by Knuppel KG's equity in the German joint venture and bears interest at 7.5% per annum. Mr. Vincent Graziano, who has retired as President and Co-Chief Executive Officer of the Company, but also remains a director of the Company, has agreed to render services to the Company on a half time/half salary basis from December 1, 1999 to December 31, 2000. The Company anticipates paying Mr. Graziano approximately $147,000 in exchange for services rendered during the fiscal year ending August 31, 2000. 41 ITEM 13. EXHIBITS AND REPORTS ON FORM 8-K.
