                     BERKSHIRE HATHAWAY FINANCE CORPORATION

                                OFFER TO EXCHANGE

        $500,000,000 PRINCIPAL AMOUNT OF ITS 4.20% SENIOR NOTES DUE 2010
     UNCONDITIONALLY GUARANTEED BY BERKSHIRE HATHAWAY INC., WHICH HAVE BEEN
 REGISTERED UNDER THE SECURITIES ACT OF 1933, FOR ANY AND ALL 4.20% SENIOR NOTES
         DUE 2010, UNCONDITIONALLY GUARANTEED BY BERKSHIRE HATHWAY INC.

                                                                [______], 2004

To Brokers, Dealers, Commercial Banks,
Trust Companies and Other Nominees:

         We are enclosing herewith an offer by Berkshire Hathaway Finance
Corporation, a Delaware corporation (the "Company"), to exchange the Company's
new 4.20% Senior Notes Due 2010 (the "Exchange Notes") which have been
registered under the Securities Act of 1933, as amended (the "Securities Act"),
for any and all of the Company's outstanding 4.20% Senior Notes Due 2010 (the
"Original Notes"), upon the terms and subject to the conditions set forth in the
accompanying Prospectus, dated [__], 2004 (as the same may be amended and
supplemented from time to time, the "Prospectus"), and related Letter of
Transmittal (which together with the Prospectus constitutes the "Exchange
Offer").

         The Exchange Offer provides a procedure for holders to tender the
Original Notes by means of guaranteed delivery.

         The Exchange Offer will expire at 5:00 p.m., New York City time, on
[___], 2004, unless extended (the "Expiration Date"). Tendered Original Notes
may be withdrawn at any time prior to 5:00 pm., New York City time, on the
Expiration Date, if such Original Notes have not previously been accepted for
exchange pursuant to the Exchange Offer.

         Based on an interpretation by the staff of the Division of Corporation
Finance of the Securities and Exchange Commission (the "SEC") as set forth in
certain interpretive letters addressed to third parties in other transactions,
Exchange Notes issued pursuant to the Exchange Offer in exchange for Original
Notes may be offered for resale, resold and otherwise transferred by a holder
thereof (other than a holder that is an "affiliate" of the Company within the
meaning of Rule 405 under the Securities Act or a "broker" or "dealer"
registered under the Securities Exchange Act of 1934, as amended (the "Exchange
Act")), without compliance with the registration and prospectus delivery
provisions of the Securities Act, provided that such Exchange Notes are acquired
in the ordinary course of such holder's business and such holder is not
engaging, does not intend to engage, and has no arrangement or understanding
with any person to participate, in the distribution of such Exchange Notes. See
"Shearman & Sterling," SEC No-Action Letter (available July 2, 1993), "Morgan
Stanley & Co., Inc.," SEC No-Action Letter (available June 5, 1991), and "Exxon
Capital Holding Corporation," SEC No-Action Letter (available May 13, 1988).
Accordingly, each broker-dealer that receives Exchange Notes for its own account
pursuant to the Exchange Offer must acknowledge that it will deliver a
Prospectus in connection with any resale of those Exchange Notes.

         The Exchange Offer is not conditioned on any minimum aggregate
principal amount of Original Notes being tendered. Original Notes may be
tendered by each holder in a minimum aggregate principal amount of $1,000 and
integral multiples of $1,000 in excess thereof.

         Notwithstanding any other provisions of the Exchange Offer, or any
extension of the Exchange Offer, the Company will not be required to accept for
exchange, or to exchange any Exchange Notes for any Original Notes and may
terminate the Exchange Offer (whether or not any Original Notes have been
accepted for exchange) or may waive any conditions to or amend the Exchange
Offer, if any of the conditions described in the Prospectus under "The Exchange
Offer--Conditions to the Exchange Offer" have occurred or exist or have not been
satisfied.
