                        SENSORMATIC EXCHANGE OFFER CLOSES

Pembroke, Bermuda and Boca Raton, FL, November 8, 2001 - Tyco International Ltd.
(NYSE: TYC; LSE: TYI; BSX: TYC), a diversified manufacturing and service
company, and Sensormatic Electronics Corporation (NYSE: SRM), a leading supplier
of electronic security solutions to the retail, commercial and industrial
marketplaces, today announced the expiration of the exchange offer by Tyco's
wholly-owned subsidiary, Tyco Acquisition Corp. XXIV (NV), for all of the
outstanding shares of Sensormatic common stock. The offer expired at 5:00 p.m.,
New York City time, on Wednesday, November 7, 2001. All shares validly tendered
have been accepted for exchange.

Tyco Acquisition was advised by Mellon Investor Services, the exchange agent for
the offer, that a total of 91,954,595 shares were tendered in the offer,
including 3,977,713 shares delivered through notice of guaranteed delivery. This
constitutes in excess of 90% of the Sensormatic common shares, including common
shares issuable upon conversion of the outstanding Sensormatic preferred shares.

The exchange ratio for the offer was 0.5189 of a Tyco common share for each
Sensormatic common share.

As soon as practicable after the conversion or redemption of all Sensormatic
preferred shares, which Sensormatic has called for redemption on November 12,
2001, Sensormatic will be merged with and into Tyco Acquisition with the
surviving company becoming a wholly-owned subsidiary of Tyco. Tyco expects that
the merger will be accomplished under short-form merger procedures without a
vote of Sensormatic stockholders. In the merger, Sensormatic stockholders






will receive the same consideration of 0.5189 of a Tyco common share per
Sensormatic common share as received by Sensormatic stockholders in the offer.
