ISCO International Consolidates Thin-film/Tower Mount Development To Illinois Headquarters

MT. PROSPECT, Ill., Nov. 12, 2001 — ISCO International, Inc. (OTC: ISCO), a global supplier of interference-control solutions for the wireless telecommunications industry, announced today that as part of its on-going efforts to streamline the Company, it has consolidated its thin-film development activities into its Illinois headquarters. The Company has closed its Louisville, Colorado facility and reduced its headcount by 19 employees. An accounting charge for this restructuring will be recognized during ISCO’s fourth quarter 2001 operating results.

The Colorado facility had been responsible for the research and development of ISCO’s patented tower mounted Cryogenic Front-End products. The facility was acquired last year to enhance ISCO’s product line, such that it now includes both thin-film and thick-film in both tower mounted and indoor configurations.

“Completing the integration of these resources into one facility will decrease costs, improve communications and speed up product development, particularly for hybrid products,” stated Dr. Amr Abdelmonem, Executive Vice President and Chief Technology Officer. “Our product plans call for combining the best product features of both thick and thin film in Advanced Cryogenic Front-Ends.”

“We had previously effected the transfer of production of our thin-film systems to our Mt. Prospect facility, where we have integrated it under our ISO-9000 program for quality assurance,” stated Chuck Willes, Chief Financial Officer of ISCO. “The further integration and streamlining of our engineering and development efforts is another step in the restructuring of ISCO from a technology-focused company to a customer-focused company. We believe that these steps will positively impact shareholder value.”

Roger Boivin, President & COO, added “We have sufficient production capability now in Illinois to support at least several hundred units per month, and bringing the development engineering under one roof makes good sense in many ways. We are being challenged now by some of our customers and potential customers to demonstrate our delivery capability, and having an integrated facility is by far the best answer.”
