CIRCLE PINES, Minn., Nov 26, 2008 (GlobeNewswire via COMTEX News Network) -- Northern Technologies International Corporation (Nasdaq:NTIC) announced today that Inter Alia Holding Company, an entity affiliated with NTIC's President and Chief Executive Officer, G. Patrick Lynch, and certain Lynch family members, including Juliane I. Lynch, the recent widow of Philip M. Lynch, former Chairman and CEO of NTIC from 1981 to 2005, has informed NTIC that Inter Alia intends to sell in private and public transactions up to an aggregate of approximately 200,000 shares of NTIC common stock, or approximately five percent of NTIC's common stock, from time to time over the next 24 months.

Mrs. Juliane I. Lynch, aged 68 and President of Inter Alia, informed NTIC's management that Inter Alia's plan to liquidate approximately 22 percent of Inter Alia's holdings of NTIC's common stock is part of a strategy to obtain liquidity and asset diversification. Inter Alia currently holds 911,668 shares or 24 percent of the total outstanding shares of NTIC and for many years has been NTIC's largest stockholder. Inter Alia has never previously sold shares of NTIC in open market transactions. In connection with its open market sales, Inter Alia may establish at a later date a trading plan under Rule 10b5-1 of the Securities Exchange Act of 1934.

Based on NTIC's currently outstanding shares of common stock, if Inter Alia were to sell as anticipated all 200,000 shares of NTIC common stock, Inter Alia would hold 711,668 shares, or 19 percent of NTIC's total outstanding shares. The transactions by Inter Alia in NTIC's common stock will be disclosed publicly as required through Form 4 and Form 144 filings with the Securities and Exchange Commission. The Form 4 filings will also be posted to NTIC's Investor Relations website.
