      NEW YORK, JULY 25, 2000 - Ogden Corporation (NYSE: OG) today announced
      that it has signed a definitive agreement with John Menzies plc to sell
      its Ogden Aviation Ground Services business for approximately $117.8
      million. In addition, the transaction includes Menzies' assumption of debt
      net of cash-on-hand. Ogden expects the cash-on-hand in the business to be
      equal to or greater than the debt assumed by Menzies. The ground services
      unit of Ogden Aviation consists of ramp, passenger and cargo handling

      previously announced strategy to sell its Entertainment and Aviation
      businesses in order to create a solid operating platform for its Energy
      business.

      "To date, with the disposition of the majority of our Entertainment
      businesses and certain other sales behind us, we have already generated
      approximately $330 million in cash and $115 million in the assumption of
      debt from our divestiture program. Today's announced sale of our ground
      services operations adds to that total, continues the momentum of the
      sales process and takes a substantial step forward in the disposition of
      our major Aviation businesses," said Scott G. Mackin, President and Chief
      Executive Officer of Ogden Corporation. "We are actively engaged in the
      process of selling our aviation fueling, fixed base operations (FBO), and
      remaining privatization assets. In addition, we are continuing to pursue
      sales processes for the remaining assets of our Entertainment division and
      for our Ogden Environmental and Energy Services consulting division. We
      will make further announcements as definitive agreements are reached."

      this year, and is subject to customary regulatory approval, approval by a
      meeting of the shareholders of John Menzies plc, bank consents and related
      issues. Shareholders representing the required majority of John Menzies'
      shares have already executed undertakings to vote in favor of the
      transaction.
