NTIC's working capital was $5,536,087 at May 31, 2010, including $1,103,620 in cash and cash equivalents. 

G. Patrick Lynch, President and Chief Executive Officer of NTIC said, "Both NTIC and many of our joint ventures experienced significant sales increases in Q3 as compared to Q3 of last year for the core business of ZERUST® corrosion inhibiting products. Many of our international joint ventures reported their best sales quarters ever which for NTIC results in fees for services and equity income from joint ventures."

Lynch continued, "While still relatively small, we are also starting to supply ZERUST® products and services to an increasing number of companies in the oil & gas industry."

"Furthermore, market acceptance of our Natur-Tec® certified fully compostable and biodegradable products continues to grow in major U.S. regional "green" hotspots including Oregon, Washington, Minnesota and New England as we have continued to make inroads with key regional and national retailers," Lynch further stated.
