| INVESTOR PRESENTATION NOVEMBER 2008 Environmentally Beneficial Materials Science. NORTHERN TECHNOLOGIES INTERNATIONAL CORPORATION

| October 08 2 Forward Looking Statements Statements contained in this presentation that are not historical information are forward-looking statements as defined within the Private Securities Litigation Reform Act of 1995. Such statements can be identified by words such as “expect,” “anticipate,” “estimate,” “will,” “would,” or words of similar meaning and any other statements that are not historical facts. Such forward-looking statements are based upon the current beliefs and expectations of NTIC’s management and are inherently subject to risks and uncertainties that could cause actual results to differ materially from those projected or implied. Such potential risks and uncertainties include, but are not limited to, in no particular order: our dependence on the success of NTIC’s joint ventures and technical fees and dividend distributions that NTIC receives from them; NTIC’s relationships with its joint ventures and its ability to maintain those relationships; risks associated with its international operations; exposure to fluctuations in foreign currency exchange rates; the current financial crises affecting the U.S. and worldwide banking system and financial markets; the contraction of the U.S. and worldwide economies, including in particular the U.S. automotive industry; the level of growth in NTIC’s markets; fluctuations in the cost and availability of raw materials, including resins and other commodities; NTIC’s investments in research and development efforts; acceptance of existing and new products; increased competition; the success of NTIC’s emerging new businesses; NTIC’s relationships with its distributors; the costs and effects of complying with changes in tax, fiscal, government and other regulatory policies, including rules relating to environmental, health and safety matters; the costs and effects of outstanding litigation; unforeseen product quality or other problems in the development, production and usage of new and existing products; loss of or changes in executive management or key employees; ability of management to manage around unplanned events; NTIC’s reliance on its intellectual property rights and the absence of infringement of the intellectual property rights of others. More detailed information on these and additional factors which could affect NTIC’s operating and financial results is described in NTIC’s filings with the Securities and Exchange Commission, including its most recent annual report on Form 10-KSB and subsequent quarterly reports on Form 10-QSB. NTIC urges all interested parties to read these reports to gain a better understanding of the many business and other risks that the company faces. Additionally, NTIC undertakes no obligation to publicly release the results of any revisions to these forward-looking statements, which may be made to reflect events or circumstances occurring after the date hereof or to reflect the occurrence of unanticipated events. Non-GAAP Financial Measures In addition to financial measures prepared in accordance with U.S. generally accepted accounting principles (GAAP), NTIC uses certain non-GAAP financial measures. In this presentation, NTIC uses the non-GAAP financial measure, net income, excluding the one-time gain on sale of assets during the first nine months of fiscal 2007. NTIC uses non-GAAP financial measures as supplemental measures of performance and believe these measures provide useful information to investors in evaluating its operations, period over period. However, non-GAAP financial measures have limitations as analytical tools, and should not be considered in isolation, or as a substitute for analysis of NTIC’s results as reported under GAAP. In addition, investors should note that any non-GAAP financial measures NTIC uses may not be the same non-GAAP financial measures, and may not be calculated in the same manner, as that of other companies. NTIC has posted a reconciliation of its non-GAAP net income, as adjusted, to the most directly comparable GAAP financial measure, net loss, on its website. Industry Information Information regarding market and industry statistics contained in this presentation is based on information available to us that we believe is accurate. It is generally based on publications that are not produced for these purposes or economic analysis. Legal Disclaimers
