Creating Shareholder Value

 .    Significant trading discount exists in Western Resources' stock

 .    Discount likely to persist
     -  Protection One Earnings continue to depress consolidated EPS
     -  Continuing holding company discount

 .    Separation of the Utility (Westar Energy) and non-electric utility assets
     (Westar Capital) will allow the market to more accurately value these
     separate companies

                                                                               3


Creating Shareholder Value

 .    Western Resources will be split into two publicly traded entities through a
     non pro rata exchange offer

     -  Westar Energy - Pure play electric utility consisting of KPL and KGE

     -  Westar Capital - Consists of Protection One Security Businesses, ONEOK,
        and Unregulated Generation.

 .  Advantages

     -  Unlocks value by creating a pure play Electric Utility

     -  Allows investors to invest in Westar Capital, which owns approximately

        security, and 45% owner of ONEOK, one of the nation's largest natural
        gas distribution companies.

                                                                               4

(1) Equivalent Forced Outage Rate is defined as the probability that a unit will
not be able to perform at full load when called upon.   EFOR is an indicator of
the time the unit was forced out due to unplanned problems or equipment repairs,
but also considers those periods when the unit is in service, but cannot reach
full capability due to unplanned component or equipment repairs.  These full
forced outages and the equivalent full outage hours of the forced deratings are
summed and compared to the actual time the utility wanted the unit in service.
The resulting statistic is the EFOR.

     -    Increased knowledge of surrounding markets, one result of which is to
          reduce our purchased power costs during contingencies
     -    Leveraging our Generating Assets
     -    Markets our "as available" energy to more distant markets than typical
          utility dispatchers can reach. Results in deeper and more profitable
          markets.
     -    Possibility to swap out our power against other trading transactions
          to minimize transmission expense
     -    Creates volume in across system transactions that can be short-stopped
          here if we lose a generating unit.
     -    Optimize transmission purchases
