 OCCIDENTAL PETROLEUM CORPORATION, a corporation duly organized and existing under the laws of the State
of Delaware (herein referred to as the “Company,” which term includes any successor under the Indenture hereinafter referred to), for value received, hereby promises to pay to
                     , or registered assigns, the lesser of (i) the Principal Amount specified above and (ii) the Principal Amount set
forth on the Schedule of Exchanges of Interests in the Global Note attached hereto on the Maturity Date specified above (unless and to the extent earlier redeemed prior to such Maturity Date) and to pay interest thereon from

provided in the Indenture, be paid to the Person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date, which shall
be the February 1 or August 1 (whether or not a Business Day), as the case may be, immediately preceding such Interest Payment Date. If any Interest Payment Date or Maturity with respect to this Note falls on a day that is not a Business

payable for the period from and after such Interest Payment Date or Maturity, as the case may be, until such following Business Day. Except as otherwise provided in the Indenture, any Defaulted Interest will forthwith cease to be payable to the
Holder on the Regular Record Date with respect to such Interest Payment Date by virtue of having been such Holder and may either (1) be paid to the Person in whose name this Note (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 (as defined below), notice of which will be given to Holders of Notes not less than 10 days prior to such Special Record Date, or
(2) be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, all as more fully provided in the
Indenture. Payment of the principal of and interest on this Note will be made at the Corporate Trust Office of the Trustee in the Borough of Manhattan, The City of New York, or at the office or agency of the Trustee maintained for that purpose in
the Borough of Manhattan, The City of New York, or at any other office or agency designated by the Company for such purpose, 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 debts; provided that, at the option of the Company, payment of interest due on any Interest Payment Date may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register
or by wire transfer of immediately available funds if appropriate wire transfer instructions have been received in writing by the Trustee not less than 15 days prior to the applicable Interest Payment Date.

 TRUSTEE’S CERTIFICATE OF AUTHENTICATION 

This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture. 

Dated: 
 The Bank of New York Mellon Trust Company, N.A., as
Trustee 
  

			
	By:	 	  

		 	Authorized Signatory







 This Note is one of a duly authorized issue of securities (herein called the
“Securities”) of the Company, issued and to be issued pursuant to the Indenture. This Note is one of a series designated by the Company as its 3.00% Senior Notes due 2027 (the “Notes”), limited in initial aggregate
principal amount to $750,000,000. The Indenture does not limit the aggregate principal amount of the Securities. 
 The
Company issued this Note pursuant to an Indenture, dated as of August 18, 2011 (herein called the “Indenture” which term, for the purpose of this Note, shall include the Officers’ Certificate dated November 7, 2016,
delivered pursuant to Sections 201 and 301 of the Indenture), between the Company 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), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and Holders of the Notes
and of the terms upon which the Notes are, and are to be, authenticated and delivered. 
 The Notes are issuable as Registered
Securities, without coupons, in denominations of $2,000 and any amount in excess thereof which is an integral multiple of $1,000. As provided in the Indenture and subject to certain limitations therein set forth, the Notes are exchangeable for a
like aggregate principal amount of Notes of like tenor of any authorized denomination, as requested by the Holder surrendering the same, upon surrender of the Note or Notes to be exchanged at any office or agency described below where Notes may be
presented for registration of transfer. 
 The Company may, from time to time, without notice to or the consent of the Holders of the Notes,
reopen this series of Notes and issue additional Notes. 
 The Notes are redeemable, in whole at any time or in part from time to time prior
to November 15, 2026, at the option of the Company at a Redemption Price equal to the greater of (i) 100% of the principal amount of the Notes to be redeemed and (ii) the sum of the present values of the remaining scheduled payments
of principal and interest on the Notes to be redeemed through November 15, 2026 (not including any portion of such payments of interest accrued to, but not including, the Redemption Date) discounted to the Redemption Date on a semi-annual basis
(assuming a 360-day year comprised of twelve 30-day months) at the Treasury Rate (as defined herein) plus 20 basis points plus, in each case, accrued and unpaid interest on the principal amount of the Notes being redeemed to, but not including, the
Redemption Date. On and after November 15, 2026, the Notes are redeemable, in whole at any time or in part from time to time, at the option of the Company at a Redemption Price equal to 100% of the principal amount of the Notes to be redeemed,
plus accrued and unpaid interest on the principal amount of the Notes being redeemed to, but not including, the Redemption Date. Notwithstanding the foregoing, installments of interest whose Stated Maturity is on or prior to the relevant Redemption
Date shall be payable to the Holders of the Notes, or one or more Predecessor Securities, of record at the close of business on the relevant Regular Record Dates according to their terms and the provisions of the Indenture. 

“Treasury Rate” means with respect to any Redemption Date, the rate per annum equal to: 







	 	•	 	the yield, under the heading that represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15” or any successor publication which is
published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for
the maturity corresponding to the Comparable Treasury Issue; provided that if no maturity is within three months before or after the remaining term of the Notes (assuming, for that purpose, that such Notes matured on November 15, 2026), yields
for the two published maturities most closely corresponding to the Comparable Treasury Issue will be determined and the Treasury Rate will be interpolated or extrapolated from those yields on a straight-line basis rounding to the nearest month; or


  

	 	•	 	if that release, or any successor release, is not published during the week preceding the calculation date or does not contain such yields, the rate per year equal to the semiannual equivalent yield to maturity of the
Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for that Redemption Date. 


The Treasury Rate will be calculated at 5:00 p.m. (New York City time) on the third Business Day preceding the Redemption Date by the
Quotation Agent. 
 “Comparable Treasury Issue” means, with respect to any Redemption Date, the United States
Treasury security selected by the Quotation Agent that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term
of the Notes (assuming, for this purpose, that the Notes matured on November 15, 2026). 
 “Comparable Treasury
Price” means, with respect to any Redemption Date, (i) the average of the Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (ii) if the
Quotation Agent obtains fewer than three Reference Treasury Dealer Quotations, the average of all such Reference Treasury Dealer Quotations, such average in any case to be determined by the Quotation Agent, or (iii) if only one Reference
Treasury Dealer Quotation is received, such Reference Treasury Dealer Quotation. 
 “Quotation Agent” means,
with respect to any Redemption Date, the Reference Treasury Dealer appointed by the Company. 
 “Reference Treasury
Dealer” means, with respect to any Redemption Date, (i) Citigroup Global Markets Inc., J.P. Morgan Securities LLC and Merrill Lynch, Pierce, Fenner & Smith Incorporated (or their respective affiliates which are primary U.S.
Government securities dealers) and their respective successors; provided, however, that if any of them shall cease to be a primary U.S. Government securities dealer in the United States of America (a
“Primary Treasury Dealer”), the Company shall substitute for it another Primary Treasury Dealer, and (ii) any other Primary Treasury Dealer or Dealers selected by the Company. 

  
 2 







 “Reference Treasury Dealer Quotations” means, with respect to each
Reference Treasury Dealer and any Redemption Date, the average, as determined by the Quotation Agent, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to
the Quotation Agent by such Reference Treasury Dealer at 5:00 p.m. (New York City time) on the third Business Day in The City of New York preceding such Redemption Date. 

Notice of any redemption will be sent at least 30 days but not more than 60 days before the Redemption Date to each Holder of the Notes to be
redeemed, all as more fully provided in the Indenture. Unless the Company defaults in payment of the Redemption Price (or any accrued and unpaid interest on the Notes or portions thereof to be redeemed), on and after the Redemption Date interest
will cease to accrue on the Notes or portions thereof called for redemption. If less than all of the Notes are to be redeemed, the Notes (or portions thereof) to be redeemed shall be selected by the Trustee by such method as the Trustee shall deem
fair and appropriate, all as more fully provided in the Indenture. 
 All notices of redemption shall state the Redemption Date, the
Redemption Price, if fewer than all the Outstanding Notes are to be redeemed, the identification (and, in the case of partial redemption, the principal amounts) of the particular Notes to be redeemed, that on the Redemption Date the Redemption Price
will become due and payable upon each Note, or portion thereof, to be redeemed, together with accrued and unpaid interest thereon, that interest on each Note, or portion thereof, called for redemption will cease to accrue on the Redemption Date and
the place or places where Notes may be surrendered for redemption. 
 In the event of redemption of this Note in part only, a new Note or
Notes of like tenor in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal amount hereof will be issued in authorized denominations in the name of the Holder hereof upon surrender hereof. 

For all purposes of this Note and the Indenture, unless the context otherwise requires, all provisions relating to the redemption by the
Company of this Note shall relate, in the case that this Note is redeemed, or to be redeemed, by the Company only in part, to that portion of the principal amount of this Note that has been, or is to be, redeemed. 

If an Event of Default with respect to Notes shall occur and be continuing, the principal of and accrued interest on the Notes may be declared
due and payable in the manner and with the effect provided in the Indenture. 
 The Indenture permits, in certain circumstances therein
specified, the amendment thereof without the consent of the Holders of the Securities. The Indenture also permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations under the
Indenture of the Company and the rights of Holders of the 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 a majority in aggregate principal amount of the
Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of a majority in aggregate principal amount of the Securities of each series at the time Outstanding, on behalf of the
Holders of all the Securities of such series, to waive 

  
 3 







 
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 Note
shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note 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 Note. 
 No reference herein to the Indenture and no provision of this Note, subject to the provisions for satisfaction and
discharge in Article Four of the Indenture, shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Note at the times, place and rate, and in the coin or currency, herein
prescribed. 
 The Indenture permits the Company, by irrevocably depositing cash or U.S. Government Obligations, in amounts and maturities
sufficient to pay and discharge at the Stated Maturity or Redemption Date, as the case may be, the entire indebtedness on all Outstanding Notes, with the Trustee in trust, solely for the benefit of the Holders of all Outstanding Notes, to defease
the Indenture with respect to the Notes (subject to specified exceptions), and, upon such deposit and satisfaction of the other conditions set forth in the Indenture, the Company shall be deemed to have paid and discharged its entire indebtedness on
the Notes. 
 As provided in the Indenture and subject to certain limitations therein set forth, the transfer of Notes is registrable in the
Security Register, upon surrender of a Note for registration of transfer at the Corporate Trust Office of the Trustee or at the office or agency of the Trustee maintained for such purpose in the Borough of Manhattan, The City of New York, or at such
other offices or agencies as the Company may designate, 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 thereof or his attorney duly
authorized in writing, and thereupon one or more new Notes of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 

No service charge shall be made by the Company, the Trustee or the Security Registrar 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 (other than exchanges pursuant to Sections 304, 305, 906 or 1107 of the Indenture not involving any transfer). 

Prior to due presentment of this Note for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may
treat the Person in whose name this Note is registered as the owner hereof for all purposes, whether or not this Note be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary. 

This Note shall be governed by and construed in accordance with the law of the State of New York (without regard to conflicts of laws
principles thereof). 
 Customary abbreviations may be used in the name of a Holder or an assignee, such as TEN COM (=tenants in common),
TEN ENT (=tenants by the entireties), JT TEN (=joint tenants with right of survivorship and not as tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors Act).

 OCCIDENTAL PETROLEUM CORPORATION, a corporation duly organized and existing under the laws of the State
of Delaware (herein referred to as the “Company,” which term includes any successor under the Indenture hereinafter referred to), for value received, hereby promises to pay to
                     , or registered assigns, the lesser of (i) the Principal Amount specified above and (ii) the Principal Amount set
forth on the Schedule of Exchanges of Interests in the Global Note attached hereto on the Maturity Date specified above (unless and to the extent earlier redeemed prior to such Maturity Date) and to pay interest thereon from
November 7, 2016 or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually in arrears on February 15 and August 15 in each year, commencing on August 15, 2017, at the
rate per annum specified above, until the principal hereof is paid or made available for payment. Interest on this Note will be computed on the basis of a 360-day year comprised of twelve 30-day months. Interest payments for this Note will include
interest accrued to but excluding each Interest Payment Date. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as  






 
provided in the Indenture, be paid to the Person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date, which shall
be the February 1 or August 1 (whether or not a Business Day), as the case may be, immediately preceding such Interest Payment Date. If any Interest Payment Date or Maturity with respect to this Note falls on a day that is not a Business
Day, the payment due on such Interest Payment Date or Maturity will be made on the next succeeding Business Day with the same force and effect as if made on such Interest Payment Date or Maturity, and no interest shall accrue on the amount so
payable for the period from and after such Interest Payment Date or Maturity, as the case may be, until such following Business Day. Except as otherwise provided in the Indenture, any Defaulted Interest will forthwith cease to be payable to the
Holder on the Regular Record Date with respect to such Interest Payment Date by virtue of having been such Holder and may either (1) be paid to the Person in whose name this Note (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 (as defined below), notice of which will be given to Holders of Notes not less than 10 days prior to such Special Record Date, or
(2) be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, all as more fully provided in the
Indenture. Payment of the principal of and interest on this Note will be made at the Corporate Trust Office of the Trustee in the Borough of Manhattan, The City of New York, or at the office or agency of the Trustee maintained for that purpose in
the Borough of Manhattan, The City of New York, or at any other office or agency designated by the Company for such purpose, 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 debts; provided that, at the option of the Company, payment of interest due on any Interest Payment Date may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register
or by wire transfer of immediately available funds if appropriate wire transfer instructions have been received in writing by the Trustee not less than 15 days prior to the applicable Interest Payment Date. 

Reference is hereby made to the further provisions of this Note set forth below, 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 or its duly

 TRUSTEE’S CERTIFICATE OF AUTHENTICATION 

This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture. 

Dated: 
 The Bank of New York Mellon Trust Company, N.A., as
Trustee 
  

			
	 By:    
	 	  

		 	 Authorized Signatory








 This Note is one of a duly authorized issue of securities (herein called the
“Securities”) of the Company, issued and to be issued pursuant to the Indenture. This Note is one of a series designated by the Company as its 4.10% Senior Notes due 2047 (the “Notes”), limited in initial aggregate
principal amount to $750,000,000. The Indenture does not limit the aggregate principal amount of the Securities. 
 The
Company issued this Note pursuant to an Indenture, dated as of August 18, 2011 (herein called the “Indenture” which term, for the purpose of this Note, shall include the Officers’ Certificate dated November 7, 2016,
delivered pursuant to Sections 201 and 301 of the Indenture), between the Company 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), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and Holders of the Notes
and of the terms upon which the Notes are, and are to be, authenticated and delivered. 
 The Notes are issuable as Registered
Securities, without coupons, in denominations of $2,000 and any amount in excess thereof which is an integral multiple of $1,000. As provided in the Indenture and subject to certain limitations therein set forth, the Notes are exchangeable for a
like aggregate principal amount of Notes of like tenor of any authorized denomination, as requested by the Holder surrendering the same, upon surrender of the Note or Notes to be exchanged at any office or agency described below where Notes may be
presented for registration of transfer. 
 The Company may, from time to time, without notice to or the consent of the Holders of the Notes,
reopen this series of Notes and issue additional Notes. 
 The Notes are redeemable, in whole at any time or in part from time to time prior
to August 15, 2046, at the option of the Company at a Redemption Price equal to the greater of (i) 100% of the principal amount of the Notes to be redeemed and (ii) the sum of the present values of the remaining scheduled
payments of principal and interest on the Notes to be redeemed through August 15, 2046 (not including any portion of such payments of interest accrued to, but not including, the Redemption Date) discounted to the Redemption Date on a
semi-annual basis (assuming a 360-day year comprised of twelve 30-day months) at the Treasury Rate (as defined herein) plus 25 basis points plus, in each case, accrued and unpaid interest on the principal amount of the Notes being redeemed to, but
not including, the Redemption Date. On and after August 15, 2046, the Notes are redeemable, in whole at any time or in part from time to time, at the option of the Company at a Redemption Price equal to 100% of the principal amount of the
Notes to be redeemed, plus accrued and unpaid interest on the principal amount of the Notes being redeemed to, but not including, the Redemption Date. Notwithstanding the foregoing, installments of interest whose Stated Maturity is on or prior to
the relevant Redemption Date shall be payable to the Holders of the Notes, or one or more Predecessor Securities, of record at the close of business on the relevant Regular Record Dates according to their terms and the provisions of the Indenture.

 “Treasury Rate” means with respect to any Redemption Date, the rate per annum equal to: 







	 	•	 	the yield, under the heading that represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15” or any successor publication which is
published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for
the maturity corresponding to the Comparable Treasury Issue; provided that if no maturity is within three months before or after the remaining term of the Notes (assuming, for that purpose, that such Notes matured on August 15, 2046), yields
for the two published maturities most closely corresponding to the Comparable Treasury Issue will be determined and the Treasury Rate will be interpolated or extrapolated from those yields on a straight-line basis rounding to the nearest month; or


  

	 	•	 	if that release, or any successor release, is not published during the week preceding the calculation date or does not contain such yields, the rate per year equal to the semiannual equivalent yield to maturity of the
Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for that Redemption Date. 


The Treasury Rate will be calculated at 5:00 p.m. (New York City time) on the third Business Day preceding the Redemption Date by the
Quotation Agent. 
 “Comparable Treasury Issue” means, with respect to any Redemption Date, the United States
Treasury security selected by the Quotation Agent that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term
of the Notes (assuming, for this purpose, that the Notes matured on August 15, 2046). 
 “Comparable Treasury
Price” means, with respect to any Redemption Date, (i) the average of the Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (ii) if the
Quotation Agent obtains fewer than three Reference Treasury Dealer Quotations, the average of all such Reference Treasury Dealer Quotations, such average in any case to be determined by the Quotation Agent, or (iii) if only one Reference
Treasury Dealer Quotation is received, such Reference Treasury Dealer Quotation. 
 “Quotation Agent” means,
with respect to any Redemption Date, the Reference Treasury Dealer appointed by the Company. 
 “Reference Treasury
Dealer” means, with respect to any Redemption Date, (i) Citigroup Global Markets Inc., J.P. Morgan Securities LLC and Merrill Lynch, Pierce, Fenner & Smith Incorporated (or their respective affiliates which are primary U.S.
Government securities dealers) and their respective successors; provided, however, that if any of them shall cease to be a primary U.S. Government securities dealer in the United States of America (a
“Primary Treasury Dealer”), the Company shall substitute for it another Primary Treasury Dealer, and (ii) any other Primary Treasury Dealer or Dealers selected by the Company. 

  
 2 







 “Reference Treasury Dealer Quotations” means, with respect to each
Reference Treasury Dealer and any Redemption Date, the average, as determined by the Quotation Agent, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to
the Quotation Agent by such Reference Treasury Dealer at 5:00 p.m. (New York City time) on the third Business Day in The City of New York preceding such Redemption Date. 

Notice of any redemption will be sent at least 30 days but not more than 60 days before the Redemption Date to each Holder of the Notes to be
redeemed, all as more fully provided in the Indenture. Unless the Company defaults in payment of the Redemption Price (or any accrued and unpaid interest on the Notes or portions thereof to be redeemed), on and after the Redemption Date interest
will cease to accrue on the Notes or portions thereof called for redemption. If less than all of the Notes are to be redeemed, the Notes (or portions thereof) to be redeemed shall be selected by the Trustee by such method as the Trustee shall deem
fair and appropriate, all as more fully provided in the Indenture. 
 All notices of redemption shall state the Redemption Date, the
Redemption Price, if fewer than all the Outstanding Notes are to be redeemed, the identification (and, in the case of partial redemption, the principal amounts) of the particular Notes to be redeemed, that on the Redemption Date the Redemption Price
will become due and payable upon each Note, or portion thereof, to be redeemed, together with accrued and unpaid interest thereon, that interest on each Note, or portion thereof, called for redemption will cease to accrue on the Redemption Date and
the place or places where Notes may be surrendered for redemption. 
 In the event of redemption of this Note in part only, a new Note or
Notes of like tenor in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal amount hereof will be issued in authorized denominations in the name of the Holder hereof upon surrender hereof. 

For all purposes of this Note and the Indenture, unless the context otherwise requires, all provisions relating to the redemption by the
Company of this Note shall relate, in the case that this Note is redeemed, or to be redeemed, by the Company only in part, to that portion of the principal amount of this Note that has been, or is to be, redeemed. 

If an Event of Default with respect to Notes shall occur and be continuing, the principal of and accrued interest on the Notes may be declared
due and payable in the manner and with the effect provided in the Indenture. 
 The Indenture permits, in certain circumstances therein
specified, the amendment thereof without the consent of the Holders of the Securities. The Indenture also permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations under the
Indenture of the Company and the rights of Holders of the 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 a majority in aggregate principal amount of the
Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of a majority in aggregate principal amount of the Securities of each series at the time Outstanding, on behalf of the
Holders of all the Securities of such series, to waive 

  
 3 







 
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 Note
shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note 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 Note. 
 No reference herein to the Indenture and no provision of this Note, subject to the provisions for satisfaction and
discharge in Article Four of the Indenture, shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Note at the times, place and rate, and in the coin or currency, herein
prescribed. 
 The Indenture permits the Company, by irrevocably depositing cash or U.S. Government Obligations, in amounts and maturities
sufficient to pay and discharge at the Stated Maturity or Redemption Date, as the case may be, the entire indebtedness on all Outstanding Notes, with the Trustee in trust, solely for the benefit of the Holders of all Outstanding Notes, to defease
the Indenture with respect to the Notes (subject to specified exceptions), and, upon such deposit and satisfaction of the other conditions set forth in the Indenture, the Company shall be deemed to have paid and discharged its entire indebtedness on
the Notes. 
 As provided in the Indenture and subject to certain limitations therein set forth, the transfer of Notes is registrable in the
Security Register, upon surrender of a Note for registration of transfer at the Corporate Trust Office of the Trustee or at the office or agency of the Trustee maintained for such purpose in the Borough of Manhattan, The City of New York, or at such
other offices or agencies as the Company may designate, 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 thereof or his attorney duly
authorized in writing, and thereupon one or more new Notes of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 

No service charge shall be made by the Company, the Trustee or the Security Registrar 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 (other than exchanges pursuant to Sections 304, 305, 906 or 1107 of the Indenture not involving any transfer). 

Prior to due presentment of this Note for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may
treat the Person in whose name this Note is registered as the owner hereof for all purposes, whether or not this Note be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary. 

This Note shall be governed by and construed in accordance with the law of the State of New York (without regard to conflicts of laws
principles thereof). 
 Customary abbreviations may be used in the name of a Holder or an assignee, such as TEN COM (=tenants in common),
TEN ENT (=tenants by the entireties), JT TEN (=joint tenants with right of survivorship and not as tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors Act).

Indenture shall have the meanings assigned to them in the Indenture.
