Forward-Looking Statements

Statements contained in this press release that are not historical information are forward-looking statements as defined within the Private Securities Litigation Reform Act of 1995. Such statements include, but are not limited to, statements about the effects of the loss of a customer on NTIC’s consolidated net sales and net income for fiscal 2008, NTIC’s effort to increase net sales by expanding the application of its corrosion inhibiting technology into the oil and gas industry and new bioplastics product line including biodegradable and compostable plastics and process technology that converts waste plastics back into diesel, gasoline and mid-distillates, NTIC’s expectations regarding the amount of research and development and marketing expenses for fiscal 2008 and such other statements which 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: the contraction of the U.S. automobile industry and its adverse effect on the demand for NTIC’s Zerust^® products, the failure of NTIC to realize any benefits, financial or otherwise, from its efforts to expand the application of its corrosion inhibiting technology into the oil and gas industry and its product line, the difficulties and risks associated with NTIC’s international operations and its corporate joint ventures, and NTIC’s reliance on its joint ventures for distributions and fees for technical services.
