              WILLIAMS INITIATES SALE OF MIDWEST PETROLEUM PIPELINE

         TULSA, Okla. - Williams (NYSE:WMB) announced today that it is pursuing
the sale of Williams Pipe Line to Williams Energy Partners L.P. (NYSE:WEG) for
at least $900 million. The sale is expected to occur before the end of the
second quarter.

         Steve Malcolm, Williams president and CEO, commented, "This is
decidedly attractive to Williams. It will add immediate cash, strengthen our
balance sheet and allow us to continue to share in the profitability of the
pipeline because of our general and limited partner interests in Williams Energy
Partners."

         Williams Pipe Line, a wholly owned subsidiary of Williams, is comprised
of 6,747 miles of active pipe that delivers petroleum products to 11 Midwestern
states. Last year, the system transported approximately 260 million barrels.

         Thirty-nine storage and distribution terminals connected to Williams
Pipe Line are included in the purchase. The facilities have an aggregate storage
capacity of 26.5 million barrels.

         Phil Wright, president of the general partner, said, "This pipeline
would give our unitholders a premier refined products system that is expected to
be nicely accretive to cash flow once we finalize the purchase price."

         Williams (NYSE:WMB) originally purchased the pipeline from Great Lakes
Pipe Line Company in 1966 for $287.6 million.
