Superconductor Technologies Inc. and Heinz Corporation
Team Up to Improve Wireless Network Performance

SANTA BARBARA, Calif. / ST. LOUIS, Mo. — November 12, 2002 – Superconductor Technologies Inc. (NASDAQ: SCON; “STI”), the global leader in high-temperature superconducting (HTS) products for wireless applications, has formed a strategic alliance with Heinz Corporation, a leading provider of services to the wireless industry, the two companies announced today at the Tower Summit & Trade Show.

As part of this new alliance, the companies will jointly provide, design and install solutions to improve the quality of wireless networks, especially in high-volume urban areas.

Initially, STI and Heinz are collecting and analyzing key RF data in several U.S. cities. A joint STI and Heinz engineering team will then use this data as the basis for designing solutions that reduce or eliminate the adverse effects of RF interference on network performance.

“The new alliance centers on the powerful blend of products and services, and the companies’ complementary expertise,” said M. Peter Thomas, president and CEO of STI. “Heinz Corporation’s data collection process dovetails nicely with our SuperLink^TM Rx technology, so this alliance makes strategic sense for our companies, customers and investors.”

STI’s patented cryogenic receiver front-ends (CRFEs) dramatically improve wireless network performance by filtering interference through the use of high-temperature superconducting (HTS) technology. With SuperFilter® at the core, the SuperLink Rx family provides both increased selectivity and sensitivity, amplifying the specific desired signal while eliminating unwanted noise.

Heinz Corporation’s services with wireless carriers cover research and data collection, wireless coverage solutions, antenna systems design and installation, tower erection and maintenance, and construction management. The company utilizes a proprietary method to collect radio frequency (RF) data for use in interference studies for wireless carriers.

“The wireless carriers are looking for economical ways to improve coverage and performance throughout their networks, especially in dense urban areas,” said Jim Heinz, president of Heinz Corporation. “STI’s SuperLink Rx products can do all that with unmatched effectiveness, while

Heinz Corporation brings our engineering services for data collection, along with the expertise to aid in the design and deployment of SuperLink solutions. This alliance brings two unique, leading-edge technology companies together, and we are excited about the prospects for our company, our partner and our customers.”

“Carriers are deploying STI’s products in urban areas to improve in-building penetration, enhance capacity, reduce interference and enable higher data throughput and speeds,” Thomas said. “Our partner, Heinz Corporation, has an outstanding record in deploying technology for all major carriers.”
