Business Wire, June 13, 2008

MINNEAPOLIS -- ADC (NASDAQ: ADCT)(www.adc.com), today announced that the company has filed a patent infringement lawsuit in the United States District Court for the District of Minnesota against AFL Telecommunications LLC. In its Complaint, ADC asserts that AFL infringes U.S. Patent Nos. 7,233,731, 7,277,620 and 7,200,317, which relate to fiber distribution hubs used in ADC's Fiber-to-the-premises (FTTP) product line.

ADC is seeking damages and an injunction to prevent the sale of AFL's fiber distribution hubs and splitter modules that incorporate one or more of ADC's patented features.

"With more than 5,000 issued and pending patents worldwide, ADC's intellectual property is one of our core assets.
