(NYSE: WR) and Protection One, Inc. (NYSE: POI) today announced that the Protection One Board of Directors authorized a private placement of common shares to Westar Capital, Inc., a wholly owned subsidiary of Western Resources. The private placement will allow Westar Capital to maintain ownership in excess of 80% of the issued and outstanding shares of Protection One's common stock following the issuance of shares of common stock to stockholders of Lifeline Systems, Inc. in connection with the acquisition of Lifeline Systems by Protection One. Under the private placement, Protection One common stock will be issued to Westar Capital at a price equal to the average closing price determined in connection with the mergers related to Protection One's acquisition of Lifeline Systems. Western Resources also indicated that Westar Capital may acquire shares of Protection One common stock in open market or privately negotiated transactions depending upon market conditions. Any open market or private purchases by Westar Capital will reduce or eliminate the need for it to purchase shares in the private placement in order to maintain at least an 80% ownership stake in Protection One. Westar Capital currently owns approximately 107.3 million shares, or about 84.6%, of Protection One's 126.8 million issued and outstanding shares. More information on the Lifeline Systems acquisition can be obtained by reviewing Protection One's preliminary information statement filed with the Securities and Exchange Commission on December 10th, 1998. As previously announced in our press release of December 21, 1998, Protection One received early termination of its filing for approval of the Lifeline Systems transaction under the Hart-Scott-Rodino Antitrust Improvements Act of 1976.
