Item 5.           Acquisition or Disposition of Assets

                  On October 16, 2002, ONEOK Inc. entered into a definitive
                  agreement with Southern Union Company to purchase all the
                  Texas gas distribution assets of Southern Union for a purchase
                  price of $420 million.

                  The gas distribution operations serve 535,000 customers in
                  cities located throughout the state of Texas, including the
                  major cities of El Paso and Austin, as well as the cities of
                  Port Arthur, Galveston, Brownsville, and others. The primary
                  growth areas are El Paso, Austin and the Rio Grande River
                  Valley. Over 90 percent of the gas customers are residential.

                  The acquisition also includes a 125 mile natural gas
                  transmission system that is regulated by the Texas Railroad
                  Commission as well as other energy related assets involved in
                  gas marketing, retail propane sales and natural gas
                  distribution investments in Mexico.

                  Operating income for these Texas assets for the twelve months
                  ending June 30, 2002, was approximately $41.2 million of which
                  approximately 95% was related to the Texas gas distribution
