WILLIAMS, BERKSHIRE HATHAWAY UNIT RECEIVE EARLY HART-SCOTT-RODINO TERMINATION FOR KERN RIVER PIPELINE SALE TULSA, Okla. -- Williams (NYSE:WMB) today announced it has received early termination of the Hart-Scott-Rodino antitrust waiting period regarding the planned sale of its Kern River pipeline system to MidAmerican Energy Holdings Company. The sale is expected to close by March 31. Additionally, Williams today will file with the Securities & Exchange Commission pro forma financial information reflecting its Kern River business as a discontinued operation to supplement Williams' previously issued consolidated financial statements included in Williams' Annual Report on Form 10-K for the year ended December 31, 2001. The pro forma financial information is included with this news release. Williams on March 7 announced that it had signed a definitive agreement with MidAmerican, one of the Berkshire Hathaway Inc. family of companies, to sell its Kern River natural gas pipeline business to MidAmerican for $450 million in cash and assumption of $510 million in debt. The sale is part of an enhanced balance-sheet improvement plan announced on March 7. This enhanced plan is designed to improve leverage and coverage ratios beyond what was envisioned in the original plan Williams presented on Dec. 19, 2001. The major rating agencies all reaffirmed Williams' credit ratings at that time. The enhanced plan fully addresses Williams' potential obligations to its former telecommunications subsidiary, Williams Communications Group, in a manner that improves Williams' financial flexibility for 2002 and beyond. Upon completion of the sale, the Kern River business will become a unit of MidAmerican. MidAmerican is expected to complete previously announced system expansion projects designed to more than double capacity to meet growing natural gas demand in the West. 4

KERN RIVER SYSTEM The Kern River pipeline is an important route for the transmission of natural gas from the vast reserves in the Rocky Mountain states to the rapidly growing markets in Utah, Nevada and California. Constructed in 1992, Kern River extends 926 miles from Opal, Wyo., to the San Joaquin Valley near Bakersfield, Calif. Kern River has a design capacity of 835 million cubic feet per day. Williams in August 2001 filed with the Federal Energy Regulatory Commission to more than double capacity on the Kern River system by adding approximately 900 million cubic feet per day of additional capacity from Wyoming to California and markets in between. Upon completion of the expansion project in May 2003, Kern River will be capable of transporting 1.7 billion cubic feet of natural gas per day. When converted to electricity, that is enough energy to power approximately 10 million homes. ABOUT BERKSHIRE HATHAWAY INC. Berkshire Hathaway Inc. is a holding company owning subsidiaries engaged in a number of diverse business activities. The most important of these is the property and casualty insurance business conducted on both a direct and reinsurance basis through a number of subsidiaries.
