February 11, 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 February 10 and August 10 in each year, commencing August 10,
2010 (each an “Interest Payment Date”), at the rate of 1.400% 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 ten (10) basis points, plus 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 bid
and asked prices for such Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing by each Reference Dealer 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, which bid and asked prices for each Reference Dealer shall be averaged by the Company. 
 “Regular Record Date” means, with respect to any Interest Payment Date, February 1 or August 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.

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

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

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

 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 twelve and one-half (12.5) basis points, plus 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

day before the relevant date fixed for redemption, which bid and asked prices for each Reference Dealer shall be averaged by the Company. 
 “Regular Record Date” means, with respect to any Interest Payment Date, February 1 or August 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.

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.

by the Schedule of Increases and Decreases in Global Security attached hereto) on February 10, 2011 (the “Stated Maturity Date”), and to pay interest thereon in arrears at a rate per annum equal to 0.230% (the “Initial Interest
Rate”) from, and including, February 11, 2010, to, but excluding, May 10, 2010, and thereafter, except as specified herein, at a rate per annum equal to LIBOR (as determined on each Interest Determination Date in accordance with the
provisions below under the heading “Determination of LIBOR”) minus 0.020% (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 (as it shall be adjusted on each Interest Payment Date and 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 Company will make payments of such interest quarterly in arrears on February 10, May 10, August 10 and November 10 of each
year (each, an “Interest Payment Date”), commencing on May 10, 2010, and on the Stated Maturity Date; provided, however, that if an Interest Payment Date, other than the Stated Maturity Date, would fall on a day that is
not a Business Day (as defined below), such Interest Payment Date will be postponed to the next Business Day and interest will accrue to but excluding the date interest is paid. However, if the postponement would cause the day to fall in the next
calendar month, such Interest Payment Date shall be the immediately preceding Business Day; provided, further, that if the Stated Maturity Date falls on a day that is not a Business Day, payment of principal, premium, if any, and/or
interest to be made on the Stated Maturity Date shall be made on the next Business Day with the same force and effect as if made on the Stated Maturity Date (without any interest or other payment in respect of such delay). For purposes of this Note,
“Business Day” means any day other than a Saturday, Sunday or other day that, in the Borough of Manhattan, New York City, banking institutions generally are authorized or obligated by law, regulation or executive order to close and
provided, further, the day must also be a London Business Day. “London Business Day” means any day on which dealings in deposits in U.S. Dollars are transacted in the London interbank market. 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 each
respective February 1, May 1, August 1 or November 1 immediately preceding such Interest Payment Date, whether or not a Business Day (each such date being referred to herein as a








 
“Regular Record Date”). 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. 
 The interest payable hereon
on each Interest Payment Date or the Stated Maturity Date, as the case may be, will include interest accrued from, and including, the most recent Interest Payment Date to which interest has been paid or duly provided for, or, if no interest has been
paid or duly provided for, from and including February 11, 2010, as the case may be, to, but excluding, such Interest Payment Date or the Stated Maturity Date, as the case may be (each, an “Interest Period”). Accrued interest on this
Debt Security will be calculated by multiplying the outstanding principal amount hereof by an accrued interest factor. Such accrued interest factor will be computed by adding the interest factors calculated for each day in the Interest Period for
which accrued interest is being paid. The interest factor for each such day is computed by dividing the Interest Rate applicable to such day by 360. The Interest Rate in effect on any Interest Payment Date will be the Interest Rate as reset in
accordance herewith on that date. The Interest Rate applicable to any other day is the Interest Rate as reset on the immediately preceding Interest Payment Date, or if none, the Initial Interest Rate. 
 This Note will bear interest at the Interest Rate (i.e. LIBOR minus 0.020%) by reference to LIBOR determined in accordance with the
provisions set forth below. Commencing with May 10, 2010 and thereafter on each succeeding Interest Payment Date specified above, the rate at which interest on this Note is payable shall be reset as of each such Interest Payment Date;
provided, however, that the Interest Rate in effect for the period from, and including, February 11, 2010 to, but excluding, May 10, 2010 (i.e. the first Interest Payment Date) will be the Initial Interest Rate. 

Except as set forth in the immediately preceding paragraph, the Interest Rate applicable to an Interest Period commencing on any Interest
Payment Date will be determined by reference to LIBOR (determined in accordance with the provisions set forth below) as of the particular “Interest Determination Date” for such period, which will be the second London Business Day preceding
the related Interest Payment Date commencing such Interest Period. Notwithstanding the foregoing, the Interest Rate hereon shall in no event be higher than the maximum rate permitted by New York law as the same may be modified by United States law
of general application. 
 Subject to applicable provisions of law and except as specified herein, the Calculation Agent will,
as of each applicable Interest Determination Date, calculate the Interest Rate payable during each applicable Interest Period in accordance with the provisions specified below. 
 Unless otherwise specified, all percentages resulting from any calculation of the rate of interest on this Note will be rounded, if
necessary, to the nearest one hundred-thousandth of a percentage point, (with .000005% rounded up to .00001%), and all U.S. dollar amounts used in or resulting from such calculation on this Note will be rounded to the nearest cent (with one-half
cent rounded upward) 







 Determination of LIBOR. “LIBOR” as of each Interest Determination Date for each
applicable Interest Period will be: (i) the rate for deposits in U.S. dollars for a period of three months, commencing on the applicable Interest Payment Date, that appears on the Reuters Screen LIBOR01 Page, or any successor service, at
approximately 11:00 a.m., London time, on the applicable Interest Determination Date, or (ii) if no such rate appears, then the calculation agent will request the principal London offices of each of four major reference banks in the London
interbank market, as selected by the Calculation Agent after consultation with the Company, to provide the Calculation Agent with its offered quotation for deposits in U.S. dollars for a period of three months, commencing on the related Interest
Payment Date commencing the applicable Interest Period, to prime banks in the London interbank market at approximately 11:00 a.m., London time, on that Interest Determination Date and in a principal amount that is representative of a single
transaction in U.S. dollars in that market at that time (the quotations referred to in this clause (ii) shall be referred to as “Offered Quotations”). If at least two Offered Quotations are provided as requested, LIBOR determined by
the Calculation Agent on that Interest Determination Date will be the arithmetic mean of those quotations. If fewer than two Offered Quotations are provided as requested, LIBOR determined by the Calculation Agent on that Interest Determination Date
will be the arithmetic mean of the rates quoted at approximately 11:00 a.m., New York time, on that Interest Determination Date, by three major banks in New York City, as selected by the Calculation Agent after consultation with the Company for
loans in U.S. dollars to leading European banks, for a period of three months, commencing on the applicable Interest Payment Date, and in a principal amount that is representative of a single transaction in U.S. dollars in that market at that time.
If the banks so selected by the Calculation Agent are not quoting as set forth above, LIBOR for the Interest Period to which that Interest Determination Date relates will remain LIBOR for the immediately preceding Interest Period, or, if there was
no preceding Interest Period, the rate of interest payable will be the Initial Interest Rate. 
 The Bank of New York Mellon
Trust Company, N.A. will be the Calculation Agent. 
 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.

 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 sum of         Million Dollars ($         ) (as revised
by the Schedule of Increases and Decreases in Global Security attached hereto) on February 10, 2012 (the “Stated Maturity Date”), and to pay interest thereon in arrears at a rate per annum equal to 0.430% (the “Initial Interest
Rate”) from, and including, February 11, 2010, to, but excluding, May 10, 2010, and thereafter, except as specified herein, at a rate per annum equal to LIBOR (as determined on each Interest Determination Date in accordance with the
provisions below under the heading “Determination of LIBOR”) plus 0.180% (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 (as it shall be adjusted on each Interest Payment Date and 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 Company will make payments of such interest quarterly in arrears on February 10, May 10, August 10 and November 10 of each
year (each, an “Interest Payment Date”), commencing on May 10, 2010, and on the Stated Maturity Date; provided, however, that if an Interest Payment Date, other than the Stated Maturity Date, would fall on a day that is
not a Business Day (as defined below), such Interest Payment Date will be postponed to the next Business Day and interest will accrue to but excluding the date interest is paid. However, if the postponement would cause the day to fall in the next
calendar month, such Interest Payment Date shall be the immediately preceding Business Day; provided, further, that if the Stated Maturity Date falls on a day that is not a Business Day, payment of principal, premium, if any, and/or
interest to be made on the Stated Maturity Date shall be made on the next Business Day with the same force and effect as if made on the Stated Maturity Date (without any interest or other payment in respect of such delay). For purposes of this Note,
“Business Day” means any day other than a Saturday, Sunday or other day that, in the Borough of Manhattan, New York City, banking institutions generally are authorized or obligated by law, regulation or executive order to close and
provided, further, the day must also be a London Business Day. “London Business Day” means any day on which dealings in deposits in U.S. Dollars are transacted in the London interbank market. 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 each
respective February 1, May 1, August 1 or November 1 immediately preceding such Interest Payment Date, whether or not a Business Day (each such date being referred to herein as a








 
“Regular Record Date”). 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. 
 The interest payable hereon
on each Interest Payment Date or the Stated Maturity Date, as the case may be, will include interest accrued from, and including, the most recent Interest Payment Date to which interest has been paid or duly provided for, or, if no interest has been
paid or duly provided for, from and including February 11, 2010, as the case may be, to, but excluding, such Interest Payment Date or the Stated Maturity Date, as the case may be (each, an “Interest Period”). Accrued interest on this
Debt Security will be calculated by multiplying the outstanding principal amount hereof by an accrued interest factor. Such accrued interest factor will be computed by adding the interest factors calculated for each day in the Interest Period for
which accrued interest is being paid. The interest factor for each such day is computed by dividing the Interest Rate applicable to such day by 360. The Interest Rate in effect on any Interest Payment Date will be the Interest Rate as reset in
accordance herewith on that date. The Interest Rate applicable to any other day is the Interest Rate as reset on the immediately preceding Interest Payment Date, or if none, the Initial Interest Rate. 
 This Note will bear interest at the Interest Rate (i.e. LIBOR plus 0.180%) by reference to LIBOR determined in accordance with the
provisions set forth below. Commencing with May 10, 2010 and thereafter on each succeeding Interest Payment Date specified above, the rate at which interest on this Note is payable shall be reset as of each such Interest Payment Date;
provided, however, that the Interest Rate in effect for the period from, and including, February 11, 2010 to, but excluding, May 10, 2010 (i.e. the first Interest Payment Date) will be the Initial Interest Rate. 

Except as set forth in the immediately preceding paragraph, the Interest Rate applicable to an Interest Period commencing on any Interest
Payment Date will be determined by reference to LIBOR (determined in accordance with the provisions set forth below) as of the particular “Interest Determination Date” for such period, which will be the second London Business Day preceding
the related Interest Payment Date commencing such Interest Period. Notwithstanding the foregoing, the Interest Rate hereon shall in no event be higher than the maximum rate permitted by New York law as the same may be modified by United States law
of general application. 
 Subject to applicable provisions of law and except as specified herein, the Calculation Agent will,
as of each applicable Interest Determination Date, calculate the Interest Rate payable during each applicable Interest Period in accordance with the provisions specified below. 
 Unless otherwise specified, all percentages resulting from any calculation of the rate of interest on this Note will be rounded, if
necessary, to the nearest one hundred-thousandth of a percentage point, (with .000005% rounded up to .00001%), and all U.S. dollar amounts used in or resulting from such calculation on this Note will be rounded to the nearest cent (with one-half
cent rounded upward) 







 Determination of LIBOR. “LIBOR” as of each Interest Determination Date for each
applicable Interest Period will be: (i) the rate for deposits in U.S. dollars for a period of three months, commencing on the applicable Interest Payment Date, that appears on the Reuters Screen LIBOR01 Page, or any successor service, at
approximately 11:00 a.m., London time, on the applicable Interest Determination Date, or (ii) if no such rate appears, then the calculation agent will request the principal London offices of each of four major reference banks in the London
interbank market, as selected by the Calculation Agent after consultation with the Company, to provide the Calculation Agent with its offered quotation for deposits in U.S. dollars for a period of three months, commencing on the related Interest
Payment Date commencing the applicable Interest Period, to prime banks in the London interbank market at approximately 11:00 a.m., London time, on that Interest Determination Date and in a principal amount that is representative of a single
transaction in U.S. dollars in that market at that time (the quotations referred to in this clause (ii) shall be referred to as “Offered Quotations”). If at least two Offered Quotations are provided as requested, LIBOR determined by
the Calculation Agent on that Interest Determination Date will be the arithmetic mean of those quotations. If fewer than two Offered Quotations are provided as requested, LIBOR determined by the Calculation Agent on that Interest Determination Date
will be the arithmetic mean of the rates quoted at approximately 11:00 a.m., New York time, on that Interest Determination Date, by three major banks in New York City, as selected by the Calculation Agent after consultation with the Company for
loans in U.S. dollars to leading European banks, for a period of three months, commencing on the applicable Interest Payment Date, and in a principal amount that is representative of a single transaction in U.S. dollars in that market at that time.
If the banks so selected by the Calculation Agent are not quoting as set forth above, LIBOR for the Interest Period to which that Interest Determination Date relates will remain LIBOR for the immediately preceding Interest Period, or, if there was
no preceding Interest Period, the rate of interest payable will be the Initial Interest Rate. 
 The Bank of New York Mellon
Trust Company, N.A. will be the Calculation Agent. 
 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.

 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 February 11, 2010 (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

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.

 Decreases in Global Security attached hereto)


 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 sum of         Million Dollars ($         ) (as revised
by the Schedule of Increases and Decreases in Global Security attached hereto) on February 11, 2013 (the “Stated Maturity Date”), and to pay interest thereon in arrears at a rate per annum equal to 0.680% (the “Initial Interest
Rate”) from, and including, February 11, 2010, to, but excluding, May 11, 2010, and thereafter, except as specified herein, at a rate per annum equal to LIBOR (as determined on each Interest Determination Date in accordance with the
provisions below under the heading “Determination of LIBOR”) plus 0.430% (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 (as it shall be adjusted on each Interest Payment Date and 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 Company will make payments of such interest quarterly in arrears on February 11, May 11, August 11 and November 11 of each
year (each, an “Interest Payment Date”), commencing on May 11, 2010, and on the Stated Maturity Date; provided, however, that if an Interest Payment Date, other than the Stated Maturity Date, would fall on a day that is
not a Business Day (as defined below), such Interest Payment Date will be postponed to the next Business Day and interest will accrue to but excluding the date interest is paid. However, if the postponement would cause the day to fall in the next
calendar month, such Interest Payment Date shall be the immediately preceding Business Day; provided, further, that if the Stated Maturity Date falls on a day that is not a Business Day, payment of principal, premium, if any, and/or
interest to be made on the Stated Maturity Date shall be made on the next Business Day with the same force and effect as if made on the Stated Maturity Date (without any interest or other payment in respect of such delay). For purposes of this Note,
“Business Day” means any day other than a Saturday, Sunday or other day that, in the Borough of Manhattan, New York City, banking institutions generally are authorized or obligated by law, regulation or executive order to close and
provided, further, the day must also be a London Business Day. “London Business Day” means any day on which dealings in deposits in U.S. Dollars are transacted in the London interbank market. 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 each
respective February 1, May 1, August 1 or November 1 immediately preceding such Interest Payment Date, whether or not a Business Day (each such date being referred to herein as a








 
“Regular Record Date”). 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. 
 The interest payable hereon
on each Interest Payment Date or the Stated Maturity Date, as the case may be, will include interest accrued from, and including, the most recent Interest Payment Date to which interest has been paid or duly provided for, or, if no interest has been
paid or duly provided for, from and including February 11, 2010, as the case may be, to, but excluding, such Interest Payment Date or the Stated Maturity Date, as the case may be (each, an “Interest Period”). Accrued interest on this
Debt Security will be calculated by multiplying the outstanding principal amount hereof by an accrued interest factor. Such accrued interest factor will be computed by adding the interest factors calculated for each day in the Interest Period for
which accrued interest is being paid. The interest factor for each such day is computed by dividing the Interest Rate applicable to such day by 360. The Interest Rate in effect on any Interest Payment Date will be the Interest Rate as reset in
accordance herewith on that date. The Interest Rate applicable to any other day is the Interest Rate as reset on the immediately preceding Interest Payment Date, or if none, the Initial Interest Rate. 
 This Note will bear interest at the Interest Rate (i.e. LIBOR plus 0.430%) by reference to LIBOR determined in accordance with the
provisions set forth below. Commencing with May 11, 2010 and thereafter on each succeeding Interest Payment Date specified above, the rate at which interest on this Note is payable shall be reset as of each such Interest Payment Date;
provided, however, that the Interest Rate in effect for the period from, and including, February 11, 2010 to, but excluding, May 11, 2010 (i.e. the first Interest Payment Date) will be the Initial Interest Rate. 

Except as set forth in the immediately preceding paragraph, the Interest Rate applicable to an Interest Period commencing on any Interest
Payment Date will be determined by reference to LIBOR (determined in accordance with the provisions set forth below) as of the particular “Interest Determination Date” for such period, which will be the second London Business Day preceding
the related Interest Payment Date commencing such Interest Period. Notwithstanding the foregoing, the Interest Rate hereon shall in no event be higher than the maximum rate permitted by New York law as the same may be modified by United States law
of general application. 
 Subject to applicable provisions of law and except as specified herein, the Calculation Agent will,
as of each applicable Interest Determination Date, calculate the Interest Rate payable during each applicable Interest Period in accordance with the provisions specified below. 
 Unless otherwise specified, all percentages resulting from any calculation of the rate of interest on this Note will be rounded, if
necessary, to the nearest one hundred-thousandth of a percentage point, (with .000005% rounded up to .00001%), and all U.S. dollar amounts used in or resulting from such calculation on this Note will be rounded to the nearest cent (with one-half
cent rounded upward) 







 Determination of LIBOR. “LIBOR” as of each Interest Determination Date for each
applicable Interest Period will be: (i) the rate for deposits in U.S. dollars for a period of three months, commencing on the applicable Interest Payment Date, that appears on the Reuters Screen LIBOR01 Page, or any successor service, at
approximately 11:00 a.m., London time, on the applicable Interest Determination Date, or (ii) if no such rate appears, then the calculation agent will request the principal London offices of each of four major reference banks in the London
interbank market, as selected by the Calculation Agent after consultation with the Company, to provide the Calculation Agent with its offered quotation for deposits in U.S. dollars for a period of three months, commencing on the related Interest
Payment Date commencing the applicable Interest Period, to prime banks in the London interbank market at approximately 11:00 a.m., London time, on that Interest Determination Date and in a principal amount that is representative of a single
transaction in U.S. dollars in that market at that time (the quotations referred to in this clause (ii) shall be referred to as “Offered Quotations”). If at least two Offered Quotations are provided as requested, LIBOR determined by
the Calculation Agent on that Interest Determination Date will be the arithmetic mean of those quotations. If fewer than two Offered Quotations are provided as requested, LIBOR determined by the Calculation Agent on that Interest Determination Date
will be the arithmetic mean of the rates quoted at approximately 11:00 a.m., New York time, on that Interest Determination Date, by three major banks in New York City, as selected by the Calculation Agent after consultation with the Company for
loans in U.S. dollars to leading European banks, for a period of three months, commencing on the applicable Interest Payment Date, and in a principal amount that is representative of a single transaction in U.S. dollars in that market at that time.
If the banks so selected by the Calculation Agent are not quoting as set forth above, LIBOR for the Interest Period to which that Interest Determination Date relates will remain LIBOR for the immediately preceding Interest Period, or, if there was
no preceding Interest Period, the rate of interest payable will be the Initial Interest Rate. 
 The Bank of New York Mellon
Trust Company, N.A. will be the Calculation Agent. 
 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.
