Business Editors & High Tech Writers

MINNEAPOLIS--(BUSINESS WIRE)--July 17, 2000

ADC Ventures, the investment arm of ADC (Nasdaq: ADCT; www.adc.com), announced today it has invested in Northstar Photonics, a start up company focused on the development of next generation laser-based optical devices. ADC's investment was part of Northstar's recently closed round of financing totaling $8.5 million, which also included investments by CIT Venture Capital and Newport Corporation.

Northstar's unique solutions are designed to provide greater wavelength stability, higher output power and reduced environmental control complexity compared to standard semi-conductor laser devices common today. The devices are designed to support fiber optic telecommunications networks by increasing speed and system bandwidth.

"This infusion of capital will further accelerate our product and process development and the market introduction of Northstar's proprietary planar waveguide laser technology," said Mark Bendett, president and CEO of Northstar Photonics, Inc.

"Northstar fits nicely into ADC Venture's objectives of investing in companies that have both high growth potential and synergies with ADC's focus on next generation optical network solutions," said Robert E. Switz, general manager of ADC Ventures and chief financial officer of ADC. "We believe that Northstar's solutions hold tremendous promise for the photonics market, and we expect they will become a key component in the successful deployment of all-optical networks."
