Tyco International Ltd. to Cancel Secondary Listing of Common Shares in London 
 
    PEMBROKE, Nov. 12 -- Tyco International Ltd. (NYSE: 
TYC; BSX: TYC; LSE: TYI) today announced that it intends to delist Tyco common 
shares from the Official List of the UK Listing Authority and from trading on 
the London Stock Exchange plc, effective from close of business on December 
12, 2003.   
    This action is being taken due to the low trading volume of Tyco shares on 
the London Stock Exchange and the costs associated with the maintenance of the 
London listing. Tyco common shares will continue to be listed on the New York 
Stock Exchange and on the Bermuda Stock Exchange.  
    Until the cancellation of the listing on close of business on December 12, 
2003, Capita Registrars (formerly IRG plc) will continue to act as Tyco's 
transfer agent in the United Kingdom.  After that date, as Tyco will no longer 
retain a branch register or transfer agent in the UK, all communications 
relating to share registration, dividends and similar matters should be sent 
to Tyco's global transfer agent, Mellon Investor Services, LLC, at Mellon 
Investor Services, LLC, 85 Challenger Road, Ridgefield Park, NJ 07660, U.S.A. 
(telephone: 001-201-329-8810).  A letter is being sent to shareholders with 
registered addresses in the UK today informing them of this change.
