MINNEAPOLIS--(BUSINESS WIRE)--May 21, 2002

ADC (Nasdaq:ADCT; www.adc.com) today announced that its Board of Directors, at the recommendation of its Audit Committee, has appointed Ernst & Young LLP as the company's independent auditors. The appointment is the result of a thorough request-for-proposal process conducted under the direction of the ADC's Audit Committee.

Ernst & Young will perform the audit of ADC's financial statements for the fiscal year ending October 31, 2002. Ernst & Young replaces Arthur Andersen LLP, who had served as ADC's auditor for many years. The decision to change auditors was not the result of any disagreement between ADC and Arthur Andersen on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure.

"Arthur Andersen has done excellent, professional work for ADC for many years and we have the utmost respect for the people with whom we have worked," said Robert E. Switz, ADC's Executive Vice President and Chief Financial Officer. "We look forward to a new relationship with Ernst & Young."

It is expected that Ernst & Young will begin immediately to review ADC's quarterly financial statements for the second quarter ended April 30, 2002 and finalize its quarterly review prior to the filing of ADC's Form 10-Q. ADC intends to proceed with the release of its unreviewed second quarter earnings as originally scheduled on Wednesday, May 22nd.
