Business Editors/High-Tech Writers

MINNEAPOLIS--(BUSINESS WIRE)--Nov. 15, 2000

ADC Ventures, the investment arm of ADC (Nasdaq:ADCT; www.adc.com), announced today it has invested in Cinta Corporation, a start-up company focused on the development of a next-generation carrier-class, ultra-scalable wavelength switch that integrates optical switching, transport capabilities and network management in a single system. This second round of funding comes from lead investor ADC Ventures, Corning, Enron Broadband Services, a subsidiary of Enron Corp. (NYSE:ENE), and Comdisco Ventures, as well as first-round investors Sequoia Capital and Battery Ventures.

With the first ultra-scalable wavelength switching system, Cinta has redefined switch functionality specifically to meet demands of both established and emerging telecommunications carriers. This next-generation solution, with its small foot print and low start-up cost, is more cost effective, significantly smaller and much easier to use than current platforms.

"It is exciting for Cinta to work with strategic partners such as ADC and prestigious venture firms with excellent track records in the telecommunications industry," said John E. Vaughan, president and CEO of Cinta. "This further validates Cinta's vision and unique product roadmap."

"The next-generation optical network will only realize its full potential with technology like the one being developed by Cinta," said Gokul Hemmady, managing director ADC Ventures. "ADC's relationship with Cinta as a key component supplier fits nicely into our objectives to invest in companies that have both high growth potential and synergies with ADC's focus on next-generation optical network solutions."
