        TYCO UPDATES EARNINGS GUIDANCE AND TIMING OF DISTRIBUTION OF CIT

PEMBROKE, BERMUDA, FEBRUARY 6, 2002--In an analyst conference call today, the
management of Tyco International Ltd. (NYSE-TYC, LSE-TYI, BSX-TYC) made the
following points:

    - Tyco's business fundamentals are strong.

    - Tyco plans to effect a distribution of CIT to Tyco shareholders as soon as
      possible and will not pursue an initial public offering of the business.
      Tyco will also consider options more lucrative to shareholders, such as
      selling the business.

    - Tyco has received strong interest from both strategic and financial buyers
      for its Plastic Division.

    - Tyco's recent shift to bank debt and exit from the commercial paper
      markets has given Tyco excess liquidity and significantly enhanced
      flexibility. The cost of the new financing structure at Tyco and CIT will
      be up to $0.15 per share in fiscal 2002.

    - The end markets for Tyco Electronics remain quite uncertain. The company
      quantified the potential negative impact to earnings from the results of
      Tyco Electronics as a range from no impact to $0.25 per share. While the
      company has seen no change of the markets for Tyco's other businesses, the
      internal distraction from the events of the past weeks may have a
      potential negative earnings impact of approximately $0.05 per share.

    - Tyco will be available to investors on a weekly conference call and more
      frequently if necessary.

The replay is scheduled to be available later in the day on February 6, 2002
until 11:59 PM on February 13, 2002. The dial-in numbers for the replay are as
follows: Domestic (U.S.) (800) 475-6701. International: (320) 365-3844. The
replay access code for all callers is: 626995.
