       TYCO APPOINTS EDWARD D. BREEN CHAIRMAN AND CHIEF EXECUTIVE OFFICER

  FORMER PRESIDENT AND COO OF MOTOROLA BRINGS OUTSTANDING LEADERSHIP EXPERIENCE
    AND TRACK RECORD AS BUILDER OF GLOBAL MANUFACTURING AND SERVICE COMPANIES

PEMBROKE, BERMUDA - JULY 25, 2002 - Tyco International Ltd. (NYSE - TYC,
BSX-TTYI) today announced that the Board of Directors has appointed Edward D.
Breen, the former President and Chief Operating Officer of Motorola, Inc., as
Chairman and Chief Executive Officer of the Company.

John F. Fort, Lead Director of Tyco, said, "The appointment of Ed Breen as
Chairman and CEO is a defining moment for Tyco. Ed has a superb record of
tackling very difficult and complex business challenges, creating effective
strategies and methodically executing on his plans. Over the years he has
delivered consistently strong results while demanding the highest standards of
corporate conduct. He developed General Instrument into an industry leader in
cable and satellite equipment manufacturing and then played a key role in
leading Motorola back to profitability. Ed has a well-earned reputation for
making the right decisions quickly with a no-nonsense management style and a
sharp focus on the interests of investors, customers and employees. Equally
important, his personal and professional integrity are unassailable."

Mr. Fort continued, "From the beginning of our search, initiated only five weeks
ago, our Board was determined to select a world-caliber executive with global
experience and unparalleled leadership qualities. We have accomplished that
goal. Ed has built businesses on an international scale and demonstrated that he
knows how to create lasting value in the companies that he runs. We considered
many highly qualified candidates for this position. Ed Breen, we concluded, is
the ideal CEO to restore investor confidence, enhance employee morale and build
on the strengths of our operating businesses."

Mr. Breen said, "This is the opportunity of a lifetime. I could not be more
excited about leading this great company, with its strong businesses and
market-leading positions. Tyco and its employees have successfully weathered a
very difficult few months, and I am confident that we will put the current
issues behind us and begin to forge ahead. All of us at Tyco have a tremendous
opportunity to build on the Company's operating strengths to realize the true
value of this enterprise.

"Over the coming weeks," Mr. Breen added, "I will develop a specific action plan
for the Company that will address four top priorities: restore confidence in
Tyco with our employees, suppliers, customers and the financial community;
enhance and strengthen the core businesses; ensure that we have the highest
standards of corporate governance in place; and create value for shareholders."
