MINNEAPOLIS & SAN JOSE, Calif.--(BUSINESS WIRE)--July 26, 2000

ADC Adds Capability to Offer Broadband Service Providers Solutions

to Generate Additional Revenues and Differentiate Services

ADC (Nasdaq: ADCT, www.adc.com) today announced that it has completed the acquisition of Centigram Communications (Nasdaq: CGRM, www.centigram.com). Effective Thursday, July 27, 2000, Centigram's shares will no longer be traded on The Nasdaq Stock Market. A letter of transmittal setting forth the procedure for surrendering stock certificates in exchange for cash payment will be sent to Centigram shareholders by Wells Fargo Shareowner Services as the Paying Agent (Telephone: [phone] or [phone]).

The cash acquisition has a fixed purchase price of approximately $200 million for all Centigram shares and stock options outstanding as of the closing date and will be accounted for using the purchase method. Due to the fixed purchase price, the per share amount of the acquisition has been determined as of the closing based on the number of outstanding Centigram shares and options on such date. As previously announced by Centigram, Centigram has entered into an agreement with the court-appointed receiver for Credit Bancorp, Ltd., which provides for the return of 900,000 treasury shares deposited by Centigram with Credit Bancorp in exchange for a cash payment of approximately $12.1 million. The court supervising the Credit Bancorp receivership approved the agreement on June 14, 2000. The period during which a party may appeal the court's order is expected to expire on or about August 22, 2000.

Because the appeal period has not expired as of the closing date, the per share amount paid to Centigram's stockholders has been calculated as if the 900,000 shares were outstanding, resulting in a cash payment of $24.12 per share to Centigram's stockholders, and $21,708,000 ($24.12 per share multiplied by 900,000 shares) in cash has been placed in escrow until expiration of the appeal period or resolution of the outstanding issues related to Centigram's treasury stock. The net amount remaining in escrow after recovery of all the treasury shares and resolution of any outstanding treasury share issues will be paid to the former Centigram stockholders and stock option holders.
