The following employee update was issued by Western Resources, Inc. on March
25, 1997:

                                                  March 25, 1997
     
     
     
          WESTERN RESOURCES RENEWS CHALLENGE TO REPUBLIC WARRANT
     
          Western Resources yesterday filed a motion with the United 
     States District Court in Florida seeking to enjoin or prohibit 
     Republic Industries, Inc. from transferring or selling 15 million 
     ADT shares that Republic purchased last week when it exercised the 
     warrant it had received in connection with its failed merger 
     agreement with ADT last summer. 

          Western Resources also seeks to enjoin Michael Ashcroft, 
     ADT's chairman, from voting the 15 million shares issued by ADT 
     as a result of Republic's exercise of the warrant. 

          In its motion papers, Western Resources asserts that the ADT 
     board of directors breached its fiduciary duties by granting and 
     amending the warrant for improper entrenchment and anti-takeover 
     purposes. Western Resources told the court that an injunction 
     would serve the public interest because it would prevent Republic 
     from unloading 15 million wrongfully issued ADT shares onto the 
     national securities exchange. 

          According to company officials, Western Resources always has 
     maintained that the warrant was detrimental for ADT's shareowners 
     because it wrongfully diluted interest in ADT and was yet another 
     entrenchment device. Now that Republic has exercised the warrant, 
     Western Resources intends to vigorously pursue its claims.
