Johns Manville to be Acquired by Berkshire Hathaway;
Announces Agreement to Repurchase Shares from Majority Owner

DENVER, Colo. & OMAHA, Neb., December 20, 2000 --- Johns Manville (NYSE: JM) and Berkshire Hathaway Inc. (NYSE: BRK. A, BRK. B) announced today that they have approved and entered into a definitive merger agreement pursuant to which Berkshire Hathaway will acquire all of the outstanding shares of Johns Manville for $13.00 per share in cash.

The merger agreement provides that, no later than January 3, 2001, a subsidiary of Berkshire Hathaway will commence a tender offer for all outstanding shares of Johns Manvilleís common stock. The Board of Directors of Johns Manville has unanimously approved the merger agreement and recommends that shareholders tender their shares into the tender offer. In addition, the Manville Personal Injury Settlement Trust (the "Trust"), which owns approximately 76 percent of the outstanding common stock of Johns Manville, has agreed to tender its shares into the offer. J.P. Morgan & Co. served as financial advisor and delivered a fairness opinion to the Board of Directors of Johns Manville.

The tender offer is subject to receiving governmental approvals, court approval of the Trustís tender and other customary conditions. Upon successful completion of the tender offer, the agreement calls for a merger pursuant to which any remaining shareholders will receive cash in the same amount as paid in the tender offer. Johns Manville will become a wholly owned subsidiary of Berkshire Hathaway and will continue to be headquartered in Denver.

Jerry Henry, Chairman & CEO of Johns Manville said, "All of us at Johns Manville are pleased to know that Warren Buffett recognizes the long term value of our company, and the consistent performance our people have delivered over the years. The transaction will allow the company to grow our business and to continue meeting our customersí needs under an ideal ownership and capital structure."

Warren Buffett, Chairman of Berkshire Hathaway said, "We are pleased about the opportunity to own a company with such strong market positions, leadership, and financial performance. Johns Manville fits well in the Berkshire family of successful enterprises with global brand recognition."

Johns Manville also announced an agreement with the Trust to repurchase approximately $135 million of its common stock from the Trust at a price of $13 per share, reflecting the purchase price in the transaction with Berkshire Hathaway. The share repurchase will result in an increase to 2000 earnings per share of approximately $0.25. Johns Manville receives a U.S. federal and state income tax deduction when the Trust distributes proceeds from the sale of company securities to a settlement fund.

Robert A. Falise, Chairman and Managing Trustee of the Trust, stated that he was confident that the required court approval would be obtained and said that the transaction would further diversify the Trustís assets and provide additional liquidity for payment of claims to its estimated one million beneficiaries. He added that the proceeds from the repurchase will be transferred to the settlement fund during 2000.

In addition, JM has agreed, subject to court approval and other conditions, to pay the Trust $90 million in settlement of JMís obligation for future income taxes of the Trust.
