 BERKSHIRE HATHAWAY INC., a corporation duly organized and existing under the laws of the State of
Delaware (herein called the “Company”, which term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay to CEDE & CO., the registered Holder hereof, the principal

on January 31 and July 31 in each year, commencing July 31, 2012 (each an “Interest Payment Date”), at the rate of 1.90% per annum (as adjusted, if at all, pursuant to such Indenture, the “Interest Rate”),
until the principal hereof is paid or made available for payment; provided that any principal, and any such installment of interest, which is overdue shall bear interest at the Interest Rate (to the extent that the payment of such interest
shall be legally enforceable), from the dates such amounts are due until they are paid or made available for payment, and such interest shall be payable on demand. The interest so payable, and punctually paid or duly provided for, on any Interest
Payment Date will, as provided in such Indenture, be paid to the Person in whose name this Debt Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest. Any such interest
not so punctually paid or duly provided for will forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name this Debt Security (or one or more Predecessor Securities) is registered at
the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of Debt Securities of this series not less than 10 days prior to such Special Record
Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Debt Securities of this series may be listed, and upon such notice as may be required by such exchange, all as
more fully provided in such Indenture. 
 Payment of the principal of and interest on this Debt Security will be made at the
office or agency of the Company maintained for that purpose in the City of New York, New York (or, if the Company does not maintain such office or agency, at the corporate trust office of the Trustee in the City of New York or if the Trustee does
not maintain an office in the City of New York, at the office of a Paying Agent in the City of New York), in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debt;
provided, however, that at the option of the Company payments of principal or interest may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register. 







 Reference is hereby made to the further provisions of this Debt Security set forth on the
reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place. 
 Unless
the certificate of authentication hereon has been executed by the Trustee referred to on the reverse hereof by manual signature, this Debt Security shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.








 IN WITNESS WHEREOF, the Company has caused this instrument to be duly executed.

 [REVERSE OF DEBT SECURITY] 

This Debt Security is one of a duly authorized series of notes of the Company (herein called the “Debt Securities”), issued and
to be issued in one or more series under an Indenture, dated as of February 1, 2010 (herein called the “Base Indenture”, and as supplemented by the Officers’ Certificate dated January 31, 2012 (the “Officers’
Certificate”), together with the Base Indenture, called the “Indenture”), among the Company, as issuer, Berkshire Hathaway Finance Corporation, and The Bank of New York Mellon Trust Company, N.A., as Trustee (herein called the
“Trustee”, which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the
Trustee and the Holders of the Debt Securities and of the terms upon which the Debt Securities are, and are to be, authenticated and delivered. 
 This Debt Security does not have the benefit of any sinking fund obligation. 

This Debt Security is not redeemable prior to the Stated Maturity Date. 

The Indenture contains provisions for defeasance at any time of the entire Indebtedness of this Debt Security or of certain restrictive
covenants and Events of Default with respect to this Debt Security, in each case upon compliance with certain conditions set forth in the Indenture. 
 If an Event of Default with respect to the Debt Securities of this series shall occur and be continuing, the principal of the Debt Securities of this series may be declared due and payable in the manner
and with the effect provided in the Indenture. 
 The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Debt Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of
the Holders of not less than 50% in principal amount of the Debt Securities at the time Outstanding of each series to be affected (voting together as a single class). The Indenture also contains provisions permitting the Holders of specified
percentages in principal amount of the Debt Securities of each series at the time Outstanding, on behalf of the Holders of all Debt Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain
past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Debt Security shall be conclusive and binding upon such Holder and upon all future Holders of this Debt Security and of any Debt Security
issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Debt Security. 
 As provided in and subject to the provisions of the Indenture, the Holder of this Debt Security shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of
a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Debt Securities of this series, the Holders of at least 25% in
principal amount of the Debt Securities of this series at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee indemnity or security
reasonably satisfactory to it, and the Trustee shall not have received from the Holders of a majority in principal amount of Debt Securities of this series at the time Outstanding a direction inconsistent with such request, and shall have failed to
institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Debt Security for the enforcement of any payment of principal
hereof or any premium or interest hereon on or after the respective due dates expressed herein. 







 No reference herein to the Indenture and no provision of this Debt Security or of the
Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any interest on this Debt Security at the times, place and rate, and in the coin or currency, herein prescribed.

 As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Debt Security is
registrable in the Security Register, upon surrender of this Debt Security for registration of transfer at the office or agency of the Company in any place where the principal of and any premium and interest on this Debt Security are payable, duly
endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or the Holder’s attorney duly authorized in writing, and thereupon one or more
new Debt Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 

The Indenture and this Debt Security are governed by the laws of the State of New York, without regard to conflicts of laws provisions
thereof. 
 The Debt Securities of this series are issuable in registered form without coupons in minimum denominations of
$2,000 and integral multiples of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Debt Securities of this series are exchangeable for a like aggregate principal amount of Debt Securities of
this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same. 
 No
service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. 

Prior to due presentment of this Debt Security for registration of transfer, the Company, the Trustee and any agent thereof may treat the
Person in whose name this Debt Security is registered as the owner hereof for all purposes, whether or not this Debt Security be overdue, and none of the Company, the Trustee or any such agent shall be affected by notice to the contrary.
