  Protection One Announces Definitive Agreement to Sell Mobile Services
  Group and Form Alliance With ATX Technologies


     CULVER CITY, Calif. and SAN ANTONIO--(BUSINESS WIRE)--June 28, 1999-
  -Protection One, Inc. (NYSE:POI), one of the nation's leading providers of
  life safety and property monitoring services and 85% owned by Western
  Resources (NYSE:WR), today announced the signing of a definitive agreement
  to sell its Mobile Services Group to ATX Technologies, Inc. for
  approximately $28.0 million, a component of which includes a preferred
  stock investment in ATX. Protection One will continue to deliver mobile
  services through an exclusive reseller arrangement with ATX.

     John E. Mack III, chief executive officer of Protection One, said,
  "Our Mobile Services Group has been a pioneer in the emerging business of
  providing security and information to the OEM automobile industry as well
  as other developing markets, including the retrofit vehicle and wireless
  communications markets. Protection One will be able to recognize a
  significant return on our investment in this business and will retain a
  meaningful equity interest through our alliance with ATX. The combination
  of ATX's expertise in the telematics market and excellence of our Mobile
  Services Group will position the two companies as a major competitor in
  the telematics industry and should result in upside equity potential for
  Protection One."

     Telematics is a relatively new service industry that combines
  wireless and location identification technologies with call center-based
  convenience and emergency response services. From navigation assistance to
  vehicle theft recovery, telematics provides drivers and fleet managers
  with immediate access to location-based information about their vehicles,
  road conditions and more.

     Steven W. Riebel, president and chief executive officer of ATX said,
  "We fully intend to become the mobile information service provider of
  choice in the wireless world, building upon the expertise that Protection
  One has developed as a leading provider of telematics services to the
  automotive industry. Together we will create a new vision that will take
  telematics solutions to a new level."

     The combined company will provide mobile services to a number of
  major companies, including Mercedes-Benz North America; Ford Motor Company
  including Ford, Jaguar and Lincoln-Mercury; the Infiniti Division of
  Nissan Motor Company; Greyhound Lines Inc.; Fujitsu Ten Corp. of America;
  Mitsubishi Electric Corporation; and Alpine Electronics of America.

     ATX intends to maintain Protection One's existing Mobile Services
  Group operations in Irving, Texas and has agreed to hire all of the
  current employees upon closing, which is expected to occur in the third
  quarter.

     ATX is recognized as one of the leaders in the mobile mayday and
  telematics industries. ATX was the first to ship a mobile mayday GPS
  tracking product for the aftermarket, the pioneer of simultaneous voice
  and data transmission over a single line and the developer of the first
  and only embedded wireless solution within a mayday product. ATX has
  helped law enforcement agencies apprehend more than 500 car thieves to
  date and has been instrumental in assisting police in the recovery of
  personal and commercial vehicles.

  One in this transaction.
