		  	(as revised by the Schedule of Increases and
 Decreases in Global Security attached hereto)

 BERKSHIRE HATHAWAY FINANCE CORPORATION, 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 sum of Five Hundred Million Dollars ($500,000,000) (as revised by the Schedule of Increases and Decreases in Global Security attached hereto) on January 15, 2040, and to pay interest thereon from and
including January 13, 2010 or from and including the most recent Interest Payment Date (as defined below) to which interest has been paid or duly provided for, semi-annually on January 15 and July 15 in each year, commencing
July 15, 2010 (each an “Interest Payment Date”), at the rate of 5.750% 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. 
 This Debt Security may be redeemed, in whole or in part, at the option of the Company, at
any time prior to its maturity at a redemption price equal to the greater of (A) 100% of the principal amount to be redeemed or (B) as determined by the Quotation Agent, the sum of the present values of the remaining scheduled payments of
principal and interest on the portion of this Debt Security being redeemed, not including any portion of such payments of interest accrued as of the date fixed for redemption, discounted to the date fixed for redemption on a semi-annual basis
assuming a 360-day year consisting of twelve 30-day months, at the Adjusted Treasury Rate plus twenty (20) basis points, plus, in each case, accrued interest on the portion of this Debt Security being redeemed to the date fixed for redemption.

 In the event of redemption of this Debt Security in part only, a new Debt Security or Debt Securities of this series and of
like tenor for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof. 
 The Quotation Agent will select a Comparable Treasury Issue, and the Reference Dealers will provide the Company and the Trustee with the Reference Dealer Quotations. The Company will calculate the Comparable Treasury Price. 
 “Adjusted Treasury Rate” means, for any date fixed for redemption, the rate per year equal to the semi-annual equivalent yield to
maturity of the Comparable Treasury Issue assuming a price for the Comparable Treasury Issue equal to the Comparable Treasury Price for the date fixed for redemption, in each case expressed as a percentage of its principal amount. 
 “Comparable Treasury Issue” means, for any date fixed for redemption, the U.S. Treasury security selected by the Quotation Agent
which has a maturity comparable to the remaining maturity of this Debt Security as of the date fixed for redemption, which would be used in accordance with customary financial practice to price new issues of corporate debt securities with a maturity
comparable to the remaining maturity of this Debt Security as of the date fixed for redemption. 
 “Comparable Treasury
Price” means, for any Comparable Treasury Issue, the price after eliminating the highest and the lowest Reference Dealer Quotations and then calculating the average of the remaining Reference Dealer Quotations; provided, however, that if
the Company obtains fewer than three Reference Dealer Quotations, the Company will, when calculating the Comparable Treasury Price, calculate the average of all the Reference Dealer Quotations and not eliminate any such quotations. 
 “Quotation Agent” means J.P. Morgan Securities Inc. or its successor. 
 “Reference Dealers” means J.P. Morgan Securities Inc. or its successor and two or more other primary U.S. Government securities
dealers in the City of New York appointed by the Company, provided, however, that if J.P. Morgan Securities Inc. or its successor ceases to be a primary U.S. Government securities dealer, the Company will appoint another primary U.S. Government
securities dealer as a substitute. 
 “Reference Dealer Quotations” means, for any Comparable Treasury Issue, the
average of the bid and asked prices for such Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing by the Reference Dealers to the Company and the Trustee as of 5:00 p.m. (New York Time) on
the third business day before the relevant date fixed for redemption. 

 “Regular Record Date” means, with respect to any Interest Payment Date,
January 1 or July 1, as the case may be, immediately preceding such Interest Payment Date. 
 The Company may elect to
effect a redemption in accordance with these provisions at any time and on any date. However, the Company must give the Holders of this Debt Security notice, as provided in the Indenture, of the redemption not less than 30 days or more than
60 days before the date fixed for redemption. If the Company elects to redeem fewer than the full principal amount of this Debt Security, the Trustee will select the amount to be redeemed on a pro rata basis, by lot or by such other method of
random selection, if any, that the Trustee deems fair and appropriate. 
 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 December 22, 2003 (herein called the “Base Indenture”, and as supplemented by the Officers’ Certificate dated January 6, 2010 (the “Officers’
Certificate”), together with the Base Indenture, called the “Indenture”), among the Company, as issuer, Berkshire Hathaway Inc., as guarantor (herein the “Guarantor” which term includes any successor Guarantor under the
Indenture) and The Bank of New York Mellon Trust Company, N.A., as successor to J.P. Morgan Trust Company, National Association 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 Guarantor, 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. 
 In accordance with resolutions attached to the
Officers’ Certificate, the following paragraph shall replace Section 501(5) of the Base Indenture for all purposes relating to the Debt Securities: 
 (5) a default under any bond, debenture, note or other evidence of Indebtedness for money borrowed by the Company, the
Guarantor or any Consolidated Subsidiary (including a default with respect to Securities of any series other than that series) having an aggregate principal amount outstanding of at least $1,000,000,000, or under any mortgage, indenture or
instrument (including this Indenture or any Guarantee) under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Company, the Guarantor or any Consolidated Subsidiary having an aggregate
principal amount outstanding of at least $1,000,000,000, whether such Indebtedness now exists or shall hereafter be created, which default (A) shall constitute a failure to pay any portion of the principal of such Indebtedness when due and
payable after the expiration of any applicable grace period with respect thereto or (B) shall have resulted in such Indebtedness becoming or being declared due and payable prior to the date on which it would otherwise have become due and
payable, without, in the case of Clause (A), such Indebtedness having been discharged or without, in the case of Clause (B), such Indebtedness having been discharged or such acceleration having been rescinded or annulled, in each such case within a
period of 15 days after there shall have been given, by registered or certified mail, to the Company and the Guarantor by the Trustee or to the Company, the Guarantor and the Trustee by the Holders of at least 25% in principal amount of the
Outstanding Securities of that series a written notice specifying such default and requiring the Company or the Guarantor, as the case may be, to cause such Indebtedness to be discharged or cause such acceleration to be rescinded or annulled, as the
case may be, and stating that such notice is a “Notice of Default” hereunder; or 
 This Debt Security does not have
the benefit of any sinking fund obligation. 
 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/or the Guarantor and the rights of the Holders of the Debt Securities and/or the Guarantees of each series to be affected under the Indenture at any time by the Company, the
Guarantor and the Trustee with the consent of the Holders of 51% in principal amount of the Debt Securities at the time Outstanding of each series to be affected. 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 and/or the Guarantor 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 not less than 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 its 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 Guarantor, 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 Guarantor, the Trustee or any such agent shall be affected by notice to the contrary. 
 All terms used in this Debt Security which are not defined herein and are defined in the Indenture shall have the meanings assigned to them in the Indenture. 

 GUARANTEE OF 
 BERKSHIRE HATHAWAY INC. 
 FOR VALUE RECEIVED,
Berkshire Hathaway Inc., a Delaware corporation (the “Guarantor”), hereby absolutely, unconditionally and irrevocably guarantees to the holders (the “Holders”) of any security authenticated and delivered (each a
“Security”) by The Bank of New York Mellon Trust Company, N.A. (as successor to J.P. Morgan Trust Company, National Association), as trustee (the “Trustee”) under that certain Indenture, dated as of December 22, 2003 (the
“Indenture”), among the Trustee, the Guarantor and Berkshire Hathaway Finance Corporation, a Delaware corporation (“Issuer”), the full and prompt payment when due (whether at stated maturity, by acceleration or otherwise) of all
present and future payment obligations of the Issuer pursuant to the terms of such Security and/or the Indenture, whether direct or indirect, absolute or contingent, and whether for principal, interest, fees, expenses, indemnification or otherwise
(collectively, the “Obligations”). Nothing herein shall be deemed to guarantee any obligation of the Issuer other than the Obligations. Nothing herein shall be deemed to guarantee any obligation of any person or entity other than the
Issuer. 
 The Guarantor’s obligations hereunder shall be unconditional and absolute, and shall not be released, discharged
or otherwise affected by (i) the existence, validity, enforceability, perfection or extent of any collateral therefor, (ii) any lack of validity or enforceability of any provision of the Security or the Indenture, (iii) any
liquidation, bankruptcy, insolvency, reorganization or other similar proceeding affecting the Issuer or its assets, or (iv) any other circumstance relating to the Obligations that might otherwise constitute a legal or equitable discharge of, or
defense to, the Guarantor. The Guarantor agrees that the Holders and/or the Trustee may resort to the Guarantor, as primary obligor and not merely as surety, for payment of any of the Obligations whether or not the Holders or the Trustee shall have
proceeded against the Issuer or any other obligor principally or secondarily obligated with respect to any of the Obligations. Neither the Holders nor the Trustee shall be obligated to file any claim relating to any of the Obligations in the event
that the Issuer becomes subject to a bankruptcy, reorganization or similar proceeding, and the failure of the Holders or the Trustee to so file shall not affect the Guarantor’s obligations hereunder. In the event that any payment to the Holders
by the Issuer in respect of any Obligations is rescinded or must otherwise be returned for any reason whatsoever, the Guarantor shall remain liable hereunder with respect to such Obligations as if such payment had not been made. 
 The Guarantor agrees that, subject to the Indenture, the Holders and/or the Trustee may at any time and from time to time, either before or
after the maturity thereof, without notice to or further consent of the Guarantor, extend the time of payment of, exchange or surrender any collateral for, or renew any of the Obligations, and may also make any agreement with the Issuer or with any
other party to or person liable on any of the Obligations or interested therein, for the extension, renewal, payment, compromise, discharge or release thereof, in whole or in part, or for any modification of the terms thereof or of any agreement
between the Holders, the Trustee and the Issuer or any such other party or person, and that none of the foregoing shall in any way impair or affect this Guarantee. The Guarantor hereby unconditionally and irrevocably waives, to the fullest extent
permitted by law, (a) notice of the acceptance of this Guarantee and of the Obligations, presentment, demand for payment, notice of dishonor and protest, (b) any requirement that any Holder exhaust any right or take any action against the
Issuer, and (c) any right to revoke this Guarantee. 
 The Guarantor agrees to pay on demand all fees and out-of-pocket
expenses incurred by the Holders or the Trustee in any way relating to the enforcement or protection of the rights of the Holders and/or the Trustee hereunder. 

 Upon payment of any of the Obligations, the Guarantor shall be subrogated to the rights of
the Holders and/or the Trustee against the Issuer with respect to such Obligations, and the Holders and the Trustee agree to take such steps, at the Guarantor’s expense, as the Guarantor may reasonably request to implement such subrogation;
provided, however, that the Guarantor shall not be entitled to enforce, or to receive any payments arising out of or based upon, such right of subrogation during any period in which any amount payable by the Issuer under the Security or the
Indenture is overdue or unpaid. 
 No failure on the part of the Holders or the Trustee to exercise, and no delay in exercising,
any right, remedy or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise by the Holders or the Trustee of any right, remedy or power hereunder preclude any other or future exercise of any right, remedy or
power. Each and every right, remedy and power hereby granted to the Holders or the Trustee or allowed any of them by law or other agreement shall be cumulative and not exclusive of any other, and may be exercised by the Holders or the Trustee at any
time or from time to time. 
 The Guarantor hereby represents and warrants that: 
 (a) the Guarantor is duly organized, validly existing and in good standing as a corporation under the laws of the State
of Delaware and has full corporate power to execute, deliver and perform this Guarantee; 
 (b) the
execution, delivery and performance of this Guarantee have been and remain duly authorized by all necessary corporate action and do not contravene any provision of the Guarantor’s certificate of incorporation or by-laws, as amended to date, or
any law, regulation, rule, decree, order, judgment or contractual restriction binding on the Guarantor or its assets; 
 (c) all consents, licenses, clearances, authorizations and approvals of, and registrations and declarations with, any governmental authority or regulatory body necessary for the due execution, delivery and performance of this Guarantee
have been obtained and remain in full force and effect and all conditions thereof have been duly complied with, and no other action by, and no notice to or filing with, any governmental authority or regulatory body is required in connection with the
execution, delivery or performance of this Guarantee; 
 (d) this Guarantee constitutes a legal, valid and
binding obligation of the Guarantor enforceable against the Guarantor in accordance with its terms, subject to bankruptcy, insolvency, reorganization, moratorium and other laws of general applicability relating to or affecting creditors’ rights
and to general equity principles; and 
 (e) there are no actions, suits or arbitration proceedings pending
or, to the knowledge of the Guarantor, threatened against it, at law or in equity, which, individually or in the aggregate, if adversely determined, would materially adversely affect the financial condition of the Guarantor or materially impair its
ability to perform its obligations under this Guarantee. 
 The Guarantor may not assign its obligations hereunder to any person
(except as permitted by the Indenture) without the prior written consent of the Holders or the Trustee. 
 All payments by the
Guarantor to the Holders or the Trustee shall be made in accordance with the provisions of the Indenture and the Security; provided, however, that payment of any fees or expenses pursuant to the fourth paragraph hereof shall be made by wire transfer
of immediately available funds to an account at a commercial bank in the United States specified to the Guarantor at least ten (10) days in advance of any demand for payment by the Holders or the Trustee. 

 All notices or demands on the Guarantor shall be deemed effective when received, shall be in
writing and shall be delivered by hand or by registered mail, or by facsimile transmission promptly confirmed by registered mail, addressed to the Guarantor at: 
 Berkshire Hathaway Inc. 
 3555 Farnam Street 
 Omaha, NE 68131
