EXPLANATORY NOTE

The sole purpose of this amendment is to remove from registration shares of common stock remaining unsold at the termination of an offering.

This Post-Effective Amendment No. 2 amends the Registration Statement on Form S-8, file number 333-62273 (the “Registration Statement”), originally filed with the Securities and Exchange Commission (the “Commission”) on August 26, 1998, as amended by the Post-Effective Amendment No. 1 thereto (the “First Amendment”), filed with the Commission on June 16, 1999. The Registration Statement relates to 11,702 shares of Class B Common Stock, par value $0.1667 per share, of Berkshire Hathaway Inc. pursuant to the Berkshire Hathaway Inc. 1996 Stock Option Plan, as Amended and Restated. The Registration Statement was filed in connection with a business combination effected on December 21, 1998 between Berkshire Hathaway Inc. (which had been renamed “OBH, Inc.” and shall be referred to herein as “Old Berkshire”) and General Re Corporation (“General Re”) (the “Merger Agreement”). Pursuant to the Merger Agreement, Old Berkshire and General Re each became wholly owned subsidiaries of NBH, Inc., a newly formed holding company (“New Berkshire”), which took the name “Berkshire Hathaway Inc.” The Merger Agreement also provided that, under certain circumstances, the business combination would have been restructured such that General Re would have merged with, and become, a wholly owned subsidiary of Old Berkshire rather than New Berkshire (the “Alternative Transaction”). Therefore, the Registration Statement constituted the registration statement of New Berkshire or, if the Alternative Transaction occurred, of Old Berkshire. Because the Alternative Transaction did not occur, and no shares of Old Berkshire common stock were issued pursuant to the Registration Statement, the First Amendment removed from registration all shares of Old Berkshire common stock registered pursuant to the Registration Statement. The Registration Statement remained the registration statement of the shares of New Berkshire common stock registered pursuant thereto. The offering of such shares of New Berkshire common stock has terminated.

New Berkshire hereby removes from registration, by means of this Post-Effective Amendment No. 2, the registered shares of New Berkshire that were unsold at the termination of the offering pursuant to the Registration Statement.
