        interest at a floating rate, reset quarterly, equal to the three-month LIBOR plus 1.250% per annum. The 2022 Floating Rate Notes will bear interest at a floating rate, reset quarterly, equal to the three-month LIBOR plus 1.450% per annum. Interest

        Floating Rate Notes, to the date for which accrued interest is being calculated. The interest factor for each day will be computed by dividing the interest rate applicable to that day by 360.

      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 CEDE & CO., 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 August 8,
        2019 or from the most recent Interest Payment Date to which interest has been paid or duly provided for, quarterly in arrears on February 8, May 8, August 8 and November 8 in each year, commencing on November 8, 2019, at the rate per annum
        specified above, until the principal hereof is paid or made available for payment. The Bank of New York Mellon Trust Company, N.A., will initially serve as the calculation agent (the “Calculation Agent”). So
        long as any Notes are outstanding there shall be at all times a Calculation Agent. If the Bank of New York Mellon Trust Company, N.A. is unable or unwilling to continue to act as the Calculation Agent, the Company will appoint another Calculation
        Agent in its place. The interest determination date for an interest period will be the second London Business Day preceding the first day of such interest period. Promptly upon determination, the Calculation Agent will inform the Trustee and the
        Company of the interest rate for the next interest period. Absent manifest error, the determination of the interest rate by the Calculation Agent shall be binding and conclusive on all Holders of the Notes, the Trustee and the Company. Interest on
        the Notes will accrue from and including August 8, 2019, to but excluding the first Interest Payment Date and then from and including the immediately preceding Interest Payment Date to which interest has been paid or duly provided for to but
        excluding the next Interest Payment Date, Redemption Date, or Maturity Date, as the case may be. Each of these periods is referred to as an “interest period”. The amount of accrued interest that the Company
        will pay for any interest period can be calculated by multiplying the face amount of the Notes of this series then Outstanding by an accrued interest factor. This accrued interest factor is computed by adding the interest factor calculated for each
        day from August 8, 2019, or from the last date the Company paid or provided for interest to the Holders of the Notes of this series, to the date for which accrued interest is being calculated. The interest factor for each day is computed by
        dividing the interest rate applicable to that day by 360. 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, May 1, August 1 or November 1 (whether or not a Business Day), as the case may be, immediately preceding such Interest
        Payment Date. If any Interest Payment Date (other than Maturity) with respect to this Note falls on a day that is not a Business Day, the Interest Payment Date shall be postponed to the next succeeding Business Day unless such next succeeding
        Business Day would be in the following month, in which case, the Interest Payment Date shall be the immediately preceding Business Day (in each case, resulting in a corresponding adjustment to the numbers of days in the applicable interest period).
        If the Maturity falls on a day that is not a Business Day, the payment of interest and principal will be made on the next succeeding Business Day with the same force and effect as if made on the Maturity, and no interest shall accrue on the amount
        so payable for the period from and after the Maturity 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.

       

      
        2

        
          


      

      On any interest determination date, LIBOR will be equal to the offered rate for deposits in U.S. dollars having an index maturity of three months, in amounts of at least
        $1,000,000, as such rate appears on Reuters Screen LIBOR01 at approximately 11:00 a.m., London time, on such interest determination date and as provided to the Calculation Agent by the Company. If no offered rate appears on Reuters Screen LIBOR01
        on an interest determination date at approximately 11:00 a.m., London time, then the Company shall select four major banks in the London interbank market and shall request each of their principal London offices to provide a quotation of the rate at
        which three-month deposits in U.S. dollars in amounts of at least $1,000,000 are offered by it to prime banks in the London interbank market, on that date and at that time, that is representative of single transactions at that time. If at least two
        quotations are provided, LIBOR will be the arithmetic average of the quotations provided. Otherwise, the Company shall select three major banks in New York City and shall request each of them to provide a quotation of the rate offered by them at
        approximately 11:00 a.m., New York City time, on the interest determination date for loans in U.S. dollars to leading European banks having an index maturity of three months for the applicable interest period in an amount of at least $1,000,000
        that is representative of single transactions at that time. If three quotations are provided, LIBOR will be the arithmetic average of the quotations provided. Otherwise, the rate of LIBOR for the next interest period will be set equal to the rate
        of LIBOR for the then current interest period. Notwithstanding the foregoing, if the Company determines that LIBOR has been permanently discontinued, the Calculation Agent shall use, as directed by the Company, as a substitute for LIBOR and for
        each future interest determination date, the alternative reference rate that by clear market consensus has replaced LIBOR in customary market usage or, if no such clear market consensus exists, the alternative reference rate selected by the central
        bank, reserve bank, monetary authority or any similar institution (including any committee or working group thereof) that is consistent with accepted market practice (the “Alternative Rate”). As part of such
        substitution, the Company shall make such adjustments (“Adjustments”) to the Alternative Rate or the spread thereon, as well as the Business Day convention, interest determination dates and related provisions
        and definitions, in each case that are consistent with accepted market practice for the use of such Alternative Rate for debt obligations such as the Notes. In the event that that there is no clear market consensus as to whether any rate has
        replaced LIBOR in customary market usage and an alternative reference rate is not selected by the central bank, reserve bank, monetary authority or any similar institution (including any committee or working group thereof) that is consistent with
        accepted market practice, the Company shall appoint, in its sole discretion, an independent financial advisor (an “IFA”) to determine an appropriate Alternative Rate and any Adjustments thereon, and the
        decision of the IFA will be binding on the Company, the Trustee and the Holders of the Notes. If, however, the Company determines that LIBOR has been discontinued, but for any reason an Alternative Rate has not been determined (and the IFA has not
        determined an Alternate Rate and Adjustments), LIBOR (for purposes of calculating the relevant interest rate) will be equal to such rate on the interest determination date when LIBOR was last available on Reuters Screen LIBOR01 and last used to
        determine the relevant interest rate.

       

      Upon request from any holder of the Notes, the Calculation Agent shall provide the interest rate in effect for the Notes for the current interest period and, if it has been determined, the interest
        rate to be in effect for the next interest period.

       

      All percentages resulting from any calculation of the interest rate on the Notes shall be rounded to the nearest one millionth of a percentage point with five ten millionths of a percentage point
        rounded upwards (e.g., 9.8765445% (or .098765445) would be rounded to 9.876545% (or .09876545)), and all dollar amounts used in or resulting from such calculation on the Notes will be rounded to the nearest cent (with one-half cent being rounded
        upwards).

       

      
        3

        
          


      

      The interest rate on the Notes will 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.

       

      “London Business Day” means any day on which dealings in deposits in U.S. dollars are transacted in the London interbank market.

       

      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 appointed co-authenticating agent by manual signature, this Note shall not be entitled to any benefit
        under the Indenture or be valid or obligatory for any purpose.

      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 Floating Rate Senior Notes due February 2021 (the “Notes”), limited in initial aggregate principal amount to $500,000,000. 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 8, 2019 (herein called the “Indenture” which term, for the purpose of this Note,
        shall include the Officer’s Certificate dated August 8, 2019, 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 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 the Notes and issue additional Notes.

       

      If (i) the merger has not been completed on or prior to May 14, 2020, or (ii) at any time prior to May 14, 2020, the merger agreement has been validly terminated (other than in connection with the
        consummation of the merger) (the earlier to occur of the events described in clause (i) or (ii), the “special mandatory redemption event”), the Company shall be required to redeem all of the Notes on the
        special mandatory redemption date (as defined below) at a redemption price (the “special mandatory redemption price”) equal to 101% of the principal amount of the Notes, plus accrued and unpaid interest, if
        any, to, but excluding, the special mandatory redemption date. Upon the occurrence of a special mandatory redemption event, the Company shall promptly (but in no event later than ten Business Days following such special mandatory redemption event)
        cause notice (a “special mandatory redemption notice”) to be delivered electronically or mailed, with a copy to the Trustee, to each Holder at its registered address (such date of notification to the Holders,
        the “special mandatory redemption notice date”). The notice will inform Holders that the Notes will be redeemed on the redemption date set forth in such notice, which will be no earlier than three Business
        Days and no later than 60 days from the special mandatory redemption notice date (such date, the “special mandatory redemption date”), and that all of the outstanding Notes will be redeemed at the special
        mandatory redemption price on the special mandatory redemption date automatically and without any further action by the Holders of the Notes. At or prior to 10:00 a.m., New York City time, on the special mandatory redemption date, the Company shall
        deposit with the Trustee funds sufficient to pay the special mandatory redemption price for all of the Notes to be redeemed. If such deposit is made as provided above, the Notes will cease to bear interest on and after the special mandatory
        redemption date.

       

      
        
          


      

      
      “merger” means the merger of Baseball Merger Sub, Inc., an indirect wholly-owned subsidiary of the Company, with and into Anadarko Petroleum Corporation
        pursuant to the merger agreement.

       

      “merger agreement” means the Agreement and Plan of Merger, dated as of May 9, 2019, by and among the Company, Anadarko Petroleum Corporation and Baseball
        Merger Sub 1, Inc.

       

      The Notes are not redeemable at the option of the Company prior to the Stated Maturity.

       

      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 (i) the Holders of not less than a majority in principal amount of the Outstanding Securities of all series voting as a single class or (ii) if fewer than all of the series of the Outstanding Securities are
        affected by such addition, change, elimination, or modification, the Holders of not less than a majority in principal amount of the Outstanding Securities of all series so affected voting as a single class (including, for the avoidance of doubt,
        consents obtained in connection with a purchase of, or tender offer or exchange for, such debt securities). The Indenture also contains provisions permitting the Holders of not less than a majority in aggregate principal amount of the Outstanding
        Securities of any series, on behalf of the Holders of all Outstanding 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 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.

        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).

      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 CEDE & CO., 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 August 8,
        2019 or from the most recent Interest Payment Date to which interest has been paid or duly provided for, quarterly in arrears on February 13, May 13, August 13 and November 13 in each year, commencing on November 13, 2019, at the rate per annum
        specified above, until the principal hereof is paid or made available for payment. The Bank of New York Mellon Trust Company, N.A., will initially serve as the calculation agent (the “Calculation Agent”). So
        long as any Notes are outstanding there shall be at all times a Calculation Agent. If the Bank of New York Mellon Trust Company, N.A. is unable or unwilling to continue to act as the Calculation Agent, the Company will appoint another Calculation
        Agent in its place. The interest determination date for an interest period will be the second London Business Day preceding the first day of such interest period. Promptly upon determination, the Calculation Agent will inform the Trustee and the
        Company of the interest rate for the next interest period. Absent manifest error, the determination of the interest rate by the Calculation Agent shall be binding and conclusive on all Holders of the Notes, the Trustee and the Company. Interest on
        the Notes will accrue from and including August 8, 2019, to but excluding the first Interest Payment Date and then from and including the immediately preceding Interest Payment Date to which interest has been paid or duly provided for to but
        excluding the next Interest Payment Date, Redemption Date, or Maturity Date, as the case may be. Each of these periods is referred to as an “interest period”. The amount of accrued interest that the Company
        will pay for any interest period can be calculated by multiplying the face amount of the Notes of this series then Outstanding by an accrued interest factor. This accrued interest factor is computed by adding the interest factor calculated for each
        day from August 8, 2019, or from the last date the Company paid or provided for interest to the Holders of the Notes of this series, to the date for which accrued interest is being calculated. The interest factor for each day is computed by
        dividing the interest rate applicable to that day by 360. 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, May 1, August 1 or November 1 (whether or not a Business Day), as the case may be, immediately preceding such Interest
        Payment Date. If any Interest Payment Date (other than Maturity) with respect to this Note falls on a day that is not a Business Day, the Interest Payment Date shall be postponed to the next succeeding Business Day unless such next succeeding
        Business Day would be in the following month, in which case, the Interest Payment Date shall be the immediately preceding Business Day (in each case, resulting in a corresponding adjustment to the numbers of days in the applicable interest period).
        If the Maturity falls on a day that is not a Business Day, the payment of interest and principal will be made on the next succeeding Business Day with the same force and effect as if made on the Maturity, and no interest shall accrue on the amount
        so payable for the period from and after the Maturity 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.

       

      
        3

        
          


      

      On any interest determination date, LIBOR will be equal to the offered rate for deposits in U.S. dollars having an index maturity of three months, in amounts of at least
        $1,000,000, as such rate appears on Reuters Screen LIBOR01 at approximately 11:00 a.m., London time, on such interest determination date and as provided to the Calculation Agent by the Company. If no offered rate appears on Reuters Screen LIBOR01
        on an interest determination date at approximately 11:00 a.m., London time, then the Company shall select four major banks in the London interbank market and shall request each of their principal London offices to provide a quotation of the rate at
        which three-month deposits in U.S. dollars in amounts of at least $1,000,000 are offered by it to prime banks in the London interbank market, on that date and at that time, that is representative of single transactions at that time. If at least two
        quotations are provided, LIBOR will be the arithmetic average of the quotations provided. Otherwise, the Company shall select three major banks in New York City and shall request each of them to provide a quotation of the rate offered by them at
        approximately 11:00 a.m., New York City time, on the interest determination date for loans in U.S. dollars to leading European banks having an index maturity of three months for the applicable interest period in an amount of at least $1,000,000
        that is representative of single transactions at that time. If three quotations are provided, LIBOR will be the arithmetic average of the quotations provided. Otherwise, the rate of LIBOR for the next interest period will be set equal to the rate
        of LIBOR for the then current interest period. Notwithstanding the foregoing, if the Company determines that LIBOR has been permanently discontinued, the Calculation Agent shall use, as directed by the Company, as a substitute for LIBOR and for
        each future interest determination date, the alternative reference rate that by clear market consensus has replaced LIBOR in customary market usage or, if no such clear market consensus exists, the alternative reference rate selected by the central
        bank, reserve bank, monetary authority or any similar institution (including any committee or working group thereof) that is consistent with accepted market practice (the “Alternative Rate”). As part of such
        substitution, the Company shall make such adjustments (“Adjustments”) to the Alternative Rate or the spread thereon, as well as the Business Day convention, interest determination dates and related provisions
        and definitions, in each case that are consistent with accepted market practice for the use of such Alternative Rate for debt obligations such as the Notes. In the event that that there is no clear market consensus as to whether any rate has
        replaced LIBOR in customary market usage and an alternative reference rate is not selected by the central bank, reserve bank, monetary authority or any similar institution (including any committee or working group thereof) that is consistent with
        accepted market practice, the Company shall appoint, in its sole discretion, an independent financial advisor (an “IFA”) to determine an appropriate Alternative Rate and any Adjustments thereon, and the
        decision of the IFA will be binding on the Company, the Trustee and the Holders of the Notes. If, however, the Company determines that LIBOR has been discontinued, but for any reason an Alternative Rate has not been determined (and the IFA has not
        determined an Alternate Rate and Adjustments), LIBOR (for purposes of calculating the relevant interest rate) will be equal to such rate on the interest determination date when LIBOR was last available on Reuters Screen LIBOR01 and last used to
        determine the relevant interest rate.

       

      Upon request from any holder of the Notes, the Calculation Agent shall provide the interest rate in effect for the Notes for the current interest period and, if it has been determined, the interest
        rate to be in effect for the next interest period.

       

      All percentages resulting from any calculation of the interest rate on the Notes shall be rounded to the nearest one millionth of a percentage point with five ten millionths of a percentage point
        rounded upwards (e.g., 9.8765445% (or .098765445) would be rounded to 9.876545% (or .09876545)), and all dollar amounts used in or resulting from such calculation on the Notes will be rounded to the nearest cent (with one-half cent being rounded
        upwards).

       

      
        4

        
          


      

      The interest rate on the Notes will 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.

       

      “London Business Day” means any day on which dealings in deposits in U.S. dollars are transacted in the London interbank market.

       

      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 appointed co-authenticating agent by manual signature, this Note shall not be entitled to any benefit
        under the Indenture or be valid or obligatory for any purpose.

      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 Floating Rate Senior Notes due August 2021 (the “Notes”), limited in initial aggregate principal amount to $500,000,000. 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 8, 2019 (herein called the “Indenture” which term, for the purpose of this Note,
        shall include the Officer’s Certificate dated August 8, 2019, 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 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 the Notes and issue additional Notes.

       

      If (i) the merger has not been completed on or prior to May 14, 2020, or (ii) at any time prior to May 14, 2020, the merger agreement has been validly terminated (other than in connection with the
        consummation of the merger) (the earlier to occur of the events described in clause (i) or (ii), the “special mandatory redemption event”), the Company shall be required to redeem all of the Notes on the
        special mandatory redemption date (as defined below) at a redemption price (the “special mandatory redemption price”) equal to 101% of the principal amount of the Notes, plus accrued and unpaid interest, if
        any, to, but excluding, the special mandatory redemption date. Upon the occurrence of a special mandatory redemption event, the Company shall promptly (but in no event later than ten Business Days following such special mandatory redemption event)
        cause notice (a “special mandatory redemption notice”) to be delivered electronically or mailed, with a copy to the Trustee, to each Holder at its registered address (such date of notification to the Holders,
        the “special mandatory redemption notice date”). The notice will inform Holders that the Notes will be redeemed on the redemption date set forth in such notice, which will be no earlier than three Business
        Days and no later than 60 days from the special mandatory redemption notice date (such date, the “special mandatory redemption date”), and that all of the outstanding Notes will be redeemed at the special
        mandatory redemption price on the special mandatory redemption date automatically and without any further action by the Holders of the Notes. At or prior to 10:00 a.m., New York City time, on the special mandatory redemption date, the Company shall
        deposit with the Trustee funds sufficient to pay the special mandatory redemption price for all of the Notes to be redeemed. If such deposit is made as provided above, the Notes will cease to bear interest on and after the special mandatory
        redemption date.

        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.

       

      Notice of any redemption will be sent at least 10 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, in the case of Global Notes, in accordance with the policies and procedures of the depository or, in the case
        of Definitive Notes, 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 (or, if not then ascertainable, the manner of calculation thereof), 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 an 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 (i) the Holders of not less than a majority in principal amount of the Outstanding Securities of all series voting as a single class or (ii) if fewer than all of the series of the Outstanding Securities are
        affected by such addition, change, elimination, or modification, the Holders of not less than a majority in principal amount of the Outstanding Securities of all series so affected voting as a single class (including, for the avoidance of doubt,
        consents obtained in connection with a purchase of, or tender offer or exchange for, such debt securities). The Indenture also contains provisions permitting the Holders of not less than a majority in aggregate principal amount of the Outstanding
        Securities of any series, on behalf of the Holders of all Outstanding 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 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), TENENT (=tenants by the entireties), JT TEN (=joint tenants with right of

      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 CEDE & CO., 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 August 8,
        2019 or from the most recent Interest Payment Date to which interest has been paid or duly provided for, quarterly in arrears on February 15, May 15, August 15 and November 15 in each year, commencing on November 15, 2019, at the rate per annum
        specified above, until the principal hereof is paid or made available for payment. The Bank of New York Mellon Trust Company, N.A., will initially serve as the calculation agent (the “Calculation Agent”). So
        long as any Notes are outstanding there shall be at all times a Calculation Agent. If the Bank of New York Mellon Trust Company, N.A. is unable or unwilling to continue to act as the Calculation Agent, the Company will appoint another Calculation
        Agent in its place. The interest determination date for an interest period will be the second London Business Day preceding the first day of such interest period. Promptly upon determination, the Calculation Agent will inform the Trustee and the
        Company of the interest rate for the next interest period. Absent manifest error, the determination of the interest rate by the Calculation Agent shall be binding and conclusive on all Holders of the Notes, the Trustee and the Company. Interest on
        the Notes will accrue from and including August 8, 2019, to but excluding the first Interest Payment Date and then from and including the immediately preceding Interest Payment Date to which interest has been paid or duly provided for to but
        excluding the next Interest Payment Date, Redemption Date, or Maturity Date, as the case may be. Each of these periods is referred to as an “interest period”. The amount of accrued interest that the Company
        will pay for any interest period can be calculated by multiplying the face amount of the Notes of this series then Outstanding by an accrued interest factor. This accrued interest factor is computed by adding the interest factor calculated for each
        day from August 8, 2019, or from the last date the Company paid or provided for interest to the Holders of the Notes of this series, to the date for which accrued interest is being calculated. The interest factor for each day is computed by
        dividing the interest rate applicable to that day by 360. 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, May 1, August 1 or November 1 (whether or not a Business Day), as the case may be, immediately preceding such Interest
        Payment Date. If any Interest Payment Date (other than Maturity) with respect to this Note falls on a day that is not a Business Day, the Interest Payment Date shall be postponed to the next succeeding Business Day unless such next succeeding
        Business Day would be in the following month, in which case, the Interest Payment Date shall be the immediately preceding Business Day (in each case, resulting in a corresponding adjustment to the numbers of days in the applicable interest period).
        If the Maturity falls on a day that is not a Business Day, the payment of interest and principal will be made on the next succeeding Business Day with the same force and effect as if made on the Maturity, and no interest shall accrue on the amount
        so payable for the period from and after the Maturity 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.

       

      
        3

        
          


      

      On any interest determination date, LIBOR will be equal to the offered rate for deposits in U.S. dollars having an index maturity of three months, in amounts of at least
        $1,000,000, as such rate appears on Reuters Screen LIBOR01 at approximately 11:00 a.m., London time, on such interest determination date and as provided to the Calculation Agent by the Company. If no offered rate appears on Reuters Screen LIBOR01
        on an interest determination date at approximately 11:00 a.m., London time, then the Company shall select four major banks in the London interbank market and shall request each of their principal London offices to provide a quotation of the rate at
        which three-month deposits in U.S. dollars in amounts of at least $1,000,000 are offered by it to prime banks in the London interbank market, on that date and at that time, that is representative of single transactions at that time. If at least two
        quotations are provided, LIBOR will be the arithmetic average of the quotations provided. Otherwise, the Company shall select three major banks in New York City and shall request each of them to provide a quotation of the rate offered by them at
        approximately 11:00 a.m., New York City time, on the interest determination date for loans in U.S. dollars to leading European banks having an index maturity of three months for the applicable interest period in an amount of at least $1,000,000
        that is representative of single transactions at that time. If three quotations are provided, LIBOR will be the arithmetic average of the quotations provided. Otherwise, the rate of LIBOR for the next interest period will be set equal to the rate
        of LIBOR for the then current interest period. Notwithstanding the foregoing, if the Company determines that LIBOR has been permanently discontinued, the Calculation Agent shall use, as directed by the Company, as a substitute for LIBOR and for
        each future interest determination date, the alternative reference rate that by clear market consensus has replaced LIBOR in customary market usage or, if no such clear market consensus exists, the alternative reference rate selected by the central
        bank, reserve bank, monetary authority or any similar institution (including any committee or working group thereof) that is consistent with accepted market practice (the “Alternative Rate”). As part of such
        substitution, the Company shall make such adjustments (“Adjustments”) to the Alternative Rate or the spread thereon, as well as the Business Day convention, interest determination dates and related provisions
        and definitions, in each case that are consistent with accepted market practice for the use of such Alternative Rate for debt obligations such as the Notes. In the event that that there is no clear market consensus as to whether any rate has
        replaced LIBOR in customary market usage and an alternative reference rate is not selected by the central bank, reserve bank, monetary authority or any similar institution (including any committee or working group thereof) that is consistent with
        accepted market practice, the Company shall appoint, in its sole discretion, an independent financial advisor (an “IFA”) to determine an appropriate Alternative Rate and any Adjustments thereon, and the
        decision of the IFA will be binding on the Company, the Trustee and the Holders of the Notes. If, however, the Company determines that LIBOR has been discontinued, but for any reason an Alternative Rate has not been determined (and the IFA has not
        determined an Alternate Rate and Adjustments), LIBOR (for purposes of calculating the relevant interest rate) will be equal to such rate on the interest determination date when LIBOR was last available on Reuters Screen LIBOR01 and last used to
        determine the relevant interest rate.

       

      Upon request from any holder of the Notes, the Calculation Agent shall provide the interest rate in effect for the Notes for the current interest period and, if it has been determined, the interest
        rate to be in effect for the next interest period.

       

      All percentages resulting from any calculation of the interest rate on the Notes shall be rounded to the nearest one millionth of a percentage point with five ten millionths of a percentage point
        rounded upwards (e.g., 9.8765445% (or .098765445) would be rounded to 9.876545% (or .09876545)), and all dollar amounts used in or resulting from such calculation on the Notes will be rounded to the nearest cent (with one-half cent being rounded
        upwards).

       

      

      
        4

        
          


      

      The interest rate on the Notes will 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.

       

      “London Business Day” means any day on which dealings in deposits in U.S. dollars are transacted in the London interbank market.

       

      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 appointed co-authenticating agent by manual signature, this Note shall not be entitled to any benefit
        under the Indenture or be valid or obligatory for any purpose.

      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 Floating Rate Senior Notes due 2022 (the “Notes”), limited in initial aggregate principal amount to $1,500,000,000. 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 8, 2019 (herein called the “Indenture” which term, for the purpose of this Note,
        shall include the Officer’s Certificate dated August 8, 2019, 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 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 the Notes and issue additional Notes.

       

      If (i) the merger has not been completed on or prior to May 14, 2020, or (ii) at any time prior to May 14, 2020, the merger agreement has been validly terminated (other than in connection with the
        consummation of the merger) (the earlier to occur of the events described in clause (i) or (ii), the “special mandatory redemption event”), the Company shall be required to redeem all of the Notes on the
        special mandatory redemption date (as defined below) at a redemption price (the “special mandatory redemption price”) equal to 101% of the principal amount of the Notes, plus accrued and unpaid interest, if
        any, to, but excluding, the special mandatory redemption date. Upon the occurrence of a special mandatory redemption event, the Company shall promptly (but in no event later than ten Business Days following such special mandatory redemption event)
        cause notice (a “special mandatory redemption notice”) to be delivered electronically or mailed, with a copy to the Trustee, to each Holder at its registered address (such date of notification to the Holders,
        the “special mandatory redemption notice date”). The notice will inform Holders that the Notes will be redeemed on the redemption date set forth in such notice, which will be no earlier than three Business
        Days and no later than 60 days from the special mandatory redemption notice date (such date, the “special mandatory redemption date”), and that all of the outstanding Notes will be redeemed at the special
        mandatory redemption price on the special mandatory redemption date automatically and without any further action by the Holders of the Notes. At or prior to 10:00 a.m., New York City time, on the special mandatory redemption date, the Company shall
        deposit with the Trustee funds sufficient to pay the special mandatory redemption price for all of the Notes to be redeemed. If such deposit is made as provided above, the Notes will cease to bear interest on and after the special mandatory
        redemption date.

       

      
        
          


      

      
      “merger” means the merger of Baseball Merger Sub, Inc., an indirect wholly-owned subsidiary of the Company, with and into Anadarko Petroleum Corporation
        pursuant to the merger agreement.

       

      “merger agreement” means the Agreement and Plan of Merger, dated as of May 9, 2019, by and among the Company, Anadarko Petroleum Corporation and Baseball
        Merger Sub 1, Inc.

       

      The Notes are redeemable, in whole or in part, at the option of the Company on August 15, 2020 or at any time for from time to time thereafter 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.

       

      Notice of any redemption will be sent at least 10 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, in the case of Global Notes, in accordance with the policies and procedures of the depository or, in the case
        of Definitive Notes, 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 (or, if not then ascertainable, the manner of calculation thereof), 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 an 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 (i) the Holders of not less than a majority in principal amount of the Outstanding Securities of all series voting as a single class or (ii) if fewer than all of the series of the Outstanding Securities are
        affected by such addition, change, elimination, or modification, the Holders of not less than a majority in principal amount of the Outstanding Securities of all series so affected voting as a single class (including, for the avoidance of doubt,
        consents obtained in connection with a purchase of, or tender offer or exchange for, such debt securities). The Indenture also contains provisions permitting the Holders of not less than a majority in aggregate principal amount of the Outstanding
        Securities of any series, on behalf of the Holders of all Outstanding 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 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), TENENT (=tenants by the entireties), JT TEN (=joint tenants with right of

      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 CEDE & CO., 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 August 8,
        2019 or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually in arrears on February 13 and August 13 in each year, commencing on February 13, 2020, 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 appointed co-authenticating agent by manual signature, this Note shall not be entitled to any benefit
        under the Indenture or be valid or obligatory for any purpose.

      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 2.600% Senior Notes due 2021 (the “Notes”), limited in initial aggregate principal amount to $1,500,000,000. The Indenture does not limit the

      The Company issued this Note pursuant to an Indenture, dated as of August 8, 2019 (herein called the “Indenture” which term, for the purpose of this Note,
        shall include the Officer’s Certificate dated August 8, 2019, 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 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 the Notes and issue additional Notes.

       

      If (i) the merger has not been completed on or prior to May 14, 2020, or (ii) at any time prior to May 14, 2020, the merger agreement has been validly terminated (other than in connection with the
        consummation of the merger) (the earlier to occur of the events described in clause (i) or (ii), the “special mandatory redemption event”), the Company shall be required to redeem all of the Notes on the
        special mandatory redemption date (as defined below) at a redemption price (the “special mandatory redemption price”) equal to 101% of the principal amount of the Notes, plus accrued and unpaid interest, if
        any, to, but excluding, the special mandatory redemption date. Upon the occurrence of a special mandatory redemption event, the Company shall promptly (but in no event later than ten Business Days following such special mandatory redemption event)
        cause notice (a “special mandatory redemption notice”) to be delivered electronically or mailed, with a copy to the Trustee, to each Holder at its registered address (such date of notification to the Holders,
        the “special mandatory redemption notice date”). The notice will inform Holders that the Notes will be redeemed on the redemption date set forth in such notice, which will be no earlier than three Business
        Days and no later than 60 days from the special mandatory redemption notice date (such date, the “special mandatory redemption date”), and that all of the outstanding Notes will be redeemed at the special
        mandatory redemption price on the special mandatory redemption date automatically and without any further action by the Holders of the Notes. At or prior to 10:00 a.m., New York City time, on the special mandatory redemption date, the Company shall
        deposit with the Trustee funds sufficient to pay the special mandatory redemption price for all of the Notes to be redeemed. If such deposit is made as provided above, the Notes will cease to bear interest on and after the special mandatory
        redemption date.

       

      
        
          


      

      
      “merger” means the merger of Baseball Merger Sub, Inc., an indirect wholly-owned subsidiary of the Company, with and into Anadarko Petroleum Corporation
        pursuant to the merger agreement.

       

      “merger agreement” means the Agreement and Plan of Merger, dated as of May 9, 2019, by and among the Company, Anadarko Petroleum Corporation and Baseball
        Merger Sub 1, Inc.

       

      The Notes are redeemable, in whole at any time or in part from time to time prior to final maturity, 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) as determined by the Quotation Agent, the sum of the present values of the remaining scheduled payments of principal and interest on the Notes to be redeemed through final maturity (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 17.5 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. 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, as determined by the Quotation Agent, 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 that 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 to be redeemed, 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 semi-annual 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.

       

      
        2

        
          


      

      “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.

       

      “Comparable Treasury Price” means, with respect to any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations for such Redemption Date,
        after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) 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 (3) 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, each of (1) BofA Securities, Inc. and Citigroup Global Markets Inc. (or their
        respective affiliates that 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 (2) any other Primary Treasury Dealer or Dealers selected by the Company.

       

      “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 10 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, in the case of Global Notes, in accordance with the policies and procedures of the depository or, in the case
        of Definitive Notes, 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 (or, if not then ascertainable, the manner of calculation thereof), 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.

       

      
        3

        
          


      

      In the event of redemption of this Note in part only, a new Note or Notes of like tenor in an 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 (i) the Holders of not less than a majority in principal amount of the Outstanding Securities of all series voting as a single class or (ii) if fewer than all of the series of the Outstanding Securities are
        affected by such addition, change, elimination, or modification, the Holders of not less than a majority in principal amount of the Outstanding Securities of all series so affected voting as a single class (including, for the avoidance of doubt,
        consents obtained in connection with a purchase of, or tender offer or exchange for, such debt securities). The Indenture also contains provisions permitting the Holders of not less than a majority in aggregate principal amount of the Outstanding
        Securities of any series, on behalf of the Holders of all Outstanding 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 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.

       

      
        4

        
          


      

      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), TENENT (=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).

       

      All undefined terms (whether or not capitalized) used in this Note which are defined in the Indenture shall have the meanings assigned to them in the Indenture.

      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 CEDE & CO., 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 August 8,
        2019 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 February 15, 2020, 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 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 2.700% Senior Notes due 2022 (the “Notes”), limited in initial aggregate principal amount to $2,000,000,000. 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 8, 2019 (herein called the “Indenture” which term, for the purpose of this Note,
        shall include the Officer’s Certificate dated August 8, 2019, 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 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 the Notes and issue additional Notes.

       

      If (i) the merger has not been completed on or prior to May 14, 2020, or (ii) at any time prior to May 14, 2020, the merger agreement has been validly terminated (other than in connection with the
        consummation of the merger) (the earlier to occur of the events described in clause (i) or (ii), the “special mandatory redemption event”), the Company shall be required to redeem all of the Notes on the
        special mandatory redemption date (as defined below) at a redemption price (the “special mandatory redemption price”) equal to 101% of the principal amount of the Notes, plus accrued and unpaid interest, if
        any, to, but excluding, the special mandatory redemption date. Upon the occurrence of a special mandatory redemption event, the Company shall promptly (but in no event later than ten Business Days following such special mandatory redemption event)
        cause notice (a “special mandatory redemption notice”) to be delivered electronically or mailed, with a copy to the Trustee, to each Holder at its registered address (such date of notification to the Holders,
        the “special mandatory redemption notice date”). The notice will inform Holders that the Notes will be redeemed on the redemption date set forth in such notice, which will be no earlier than three Business
        Days and no later than 60 days from the special mandatory redemption notice date (such date, the “special mandatory redemption date”), and that all of the outstanding Notes will be redeemed at the special
        mandatory redemption price on the special mandatory redemption date automatically and without any further action by the Holders of the Notes. At or prior to 10:00 a.m., New York City time, on the special mandatory redemption date, the Company shall
        deposit with the Trustee funds sufficient to pay the special mandatory redemption price for all of the Notes to be redeemed. If such deposit is made as provided above, the Notes will cease to bear interest on and after the special mandatory
        redemption date.

      “merger” means the merger of Baseball Merger Sub, Inc., an indirect wholly-owned subsidiary of the Company, with and into Anadarko Petroleum Corporation
        pursuant to the merger agreement.

       

      “merger agreement” means the Agreement and Plan of Merger, dated as of May 9, 2019, by and among the Company, Anadarko Petroleum Corporation and Baseball
        Merger Sub 1, Inc.

       

      The Notes are redeemable, in whole at any time or in part from time to time prior to final maturity, 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) as determined by the Quotation Agent, the sum of the present values of the remaining scheduled payments of principal and interest on the Notes to be redeemed through final maturity (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. 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, as determined by the Quotation Agent, 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 that 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 to be redeemed, 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 semi-annual 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.

       

      
        2

        
          


      

      “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.

       

      “Comparable Treasury Price” means, with respect to any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations for such Redemption Date,
        after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) 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 (3) 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, each of (1) BofA Securities, Inc. and Citigroup Global Markets Inc. (or their
        respective affiliates that 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 (2) any other Primary Treasury Dealer or Dealers selected by the Company.

       

      “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 10 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, in the case of Global Notes, in accordance with the policies and procedures of the depository or, in the case
        of Definitive Notes, 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 (or, if not then ascertainable, the manner of calculation thereof), 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.

       

      
        3

        
          


      

      In the event of redemption of this Note in part only, a new Note or Notes of like tenor in an 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 (i) the Holders of not less than a majority in principal amount of the Outstanding Securities of all series voting as a single class or (ii) if fewer than all of the series of the Outstanding Securities are
        affected by such addition, change, elimination, or modification, the Holders of not less than a majority in principal amount of the Outstanding Securities of all series so affected voting as a single class (including, for the avoidance of doubt,
        consents obtained in connection with a purchase of, or tender offer or exchange for, such debt securities). The Indenture also contains provisions permitting the Holders of not less than a majority in aggregate principal amount of the Outstanding
        Securities of any series, on behalf of the Holders of all Outstanding 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 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.

       

      
        4

        
          


      

      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), TENENT (=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).

       

      All undefined terms (whether or not capitalized) used in this Note which are defined in the Indenture shall have the meanings assigned to them in the Indenture.

      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 CEDE & CO., 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 August 8,
        2019 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 February 15, 2020, 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 appointed co-authenticating agent by manual signature, this Note shall not be entitled to any benefit
        under the Indenture or be valid or obligatory for any purpose.

      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 2.900% Senior Notes due 2024 (the “Notes”), limited in initial aggregate principal amount to $3,000,000,000. 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 8, 2019 (herein called the “Indenture” which term, for the purpose of this Note,
        shall include the Officer’s Certificate dated August 8, 2019, 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 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 the Notes and issue additional Notes.

       

      If (i) the merger has not been completed on or prior to May 14, 2020, or (ii) at any time prior to May 14, 2020, the merger agreement has been validly terminated (other than in connection with the
        consummation of the merger) (the earlier to occur of the events described in clause (i) or (ii), the “special mandatory redemption event”), the Company shall be required to redeem all of the Notes on the
        special mandatory redemption date (as defined below) at a redemption price (the “special mandatory redemption price”) equal to 101% of the principal amount of the Notes, plus accrued and unpaid interest, if
        any, to, but excluding, the special mandatory redemption date. Upon the occurrence of a special mandatory redemption event, the Company shall promptly (but in no event later than ten Business Days following such special mandatory redemption event)
        cause notice (a “special mandatory redemption notice”) to be delivered electronically or mailed, with a copy to the Trustee, to each Holder at its registered address (such date of notification to the Holders,
        the “special mandatory redemption notice date”). The notice will inform Holders that the Notes will be redeemed on the redemption date set forth in such notice, which will be no earlier than three Business
        Days and no later than 60 days from the special mandatory redemption notice date (such date, the “special mandatory redemption date”), and that all of the outstanding Notes will be redeemed at the special
        mandatory redemption price on the special mandatory redemption date automatically and without any further action by the Holders of the Notes. At or prior to 10:00 a.m., New York City time, on the special mandatory redemption date, the Company shall
        deposit with the Trustee funds sufficient to pay the special mandatory redemption price for all of the Notes to be redeemed. If such deposit is made as provided above, the Notes will cease to bear interest on and after the special mandatory
        redemption date.

       

      
        
          


      

      
      “merger” means the merger of Baseball Merger Sub, Inc., an indirect wholly-owned subsidiary of the Company, with and into Anadarko Petroleum Corporation
        pursuant to the merger agreement.

       

      “merger agreement” means the Agreement and Plan of Merger, dated as of May 9, 2019, by and among the Company, Anadarko Petroleum Corporation and Baseball
        Merger Sub 1, Inc.

       

      The Notes are redeemable, in whole at any time or in part from time to time prior to July 15, 2024 (the “Par Call Date”), 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) as determined by the Quotation Agent, the sum of the present values of the remaining scheduled payments of principal and interest on the
        Notes to be redeemed through the Par Call Date (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 the
        Par Call Date, 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, as determined by the Quotation Agent, 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 that 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 to be redeemed (assuming, for this purpose, that the Notes mature on the Par Call Date),
                    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 semi-annual 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.

                


        

      

       

      
        2

        
          


      

      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 mature
        on the Par Call Date).

       

      “Comparable Treasury Price” means, with respect to any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations for such Redemption Date,
        after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) 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 (3) 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, each of (1) BofA Securities, Inc. and Citigroup Global Markets Inc. (or their
        respective affiliates that 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 (2) any other Primary Treasury Dealer or Dealers selected by the Company.

       

      “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 10 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, in the case of Global Notes, in accordance with the policies and procedures of the depository or, in the case
        of Definitive Notes, by the Trustee by such method as the Trustee shall deem fair and appropriate, all as more fully provided in the Indenture.

       

      
        3

        
          


      

      All notices of redemption shall state the Redemption Date, the Redemption Price (or, if not then ascertainable, the manner of calculation thereof), 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 an 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 (i) the Holders of not less than a majority in principal amount of the Outstanding Securities of all series voting as a single class or (ii) if fewer than all of the series of the Outstanding Securities are
        affected by such addition, change, elimination, or modification, the Holders of not less than a majority in principal amount of the Outstanding Securities of all series so affected voting as a single class (including, for the avoidance of doubt,
        consents obtained in connection with a purchase of, or tender offer or exchange for, such debt securities). The Indenture also contains provisions permitting the Holders of not less than a majority in aggregate principal amount of the Outstanding
        Securities of any series, on behalf of the Holders of all Outstanding 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 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.

       

      
        4

        
          


      

      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), TENENT (=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).

       

      All undefined terms (whether or not capitalized) used in this Note which are defined in the Indenture shall have the meanings assigned to them in the Indenture.

          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 CEDE & CO., 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 August
            8, 2019 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 February 15, 2020, 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 appointed co-authenticating agent by manual signature, this Note shall not be entitled to any
            benefit under the Indenture or be valid or obligatory for any purpose.

          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 3.200% Senior Notes due 2026 (the “Notes”), limited in initial aggregate principal amount to $1,000,000,000. 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 8, 2019 (herein called the “Indenture” which term, for the purpose of this
            Note, shall include the Officer’s Certificate dated August 8, 2019, 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 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 the Notes and issue additional Notes.

           

          If (i) the merger has not been completed on or prior to May 14, 2020, or (ii) at any time prior to May 14, 2020, the merger agreement has been validly terminated (other than in connection with
            the consummation of the merger) (the earlier to occur of the events described in clause (i) or (ii), the “special mandatory redemption event”), the Company shall be required to redeem all of the Notes on
            the special mandatory redemption date (as defined below) at a redemption price (the “special mandatory redemption price”) equal to 101% of the principal amount of the Notes, plus accrued and unpaid
            interest, if any, to, but excluding, the special mandatory redemption date. Upon the occurrence of a special mandatory redemption event, the Company shall promptly (but in no event later than ten Business Days following such special mandatory
            redemption event) cause notice (a “special mandatory redemption notice”) to be delivered electronically or mailed, with a copy to the Trustee, to each Holder at its registered address (such date of
            notification to the Holders, the “special mandatory redemption notice date”). The notice will inform Holders that the Notes will be redeemed on the redemption date set forth in such notice, which will be
            no earlier than three Business Days and no later than 60 days from the special mandatory redemption notice date (such date, the “special mandatory redemption date”), and that all of the outstanding Notes
            will be redeemed at the special mandatory redemption price on the special mandatory redemption date automatically and without any further action by the Holders of the Notes. At or prior to 10:00 a.m., New York City time, on the special
            mandatory redemption date, the Company shall deposit with the Trustee funds sufficient to pay the special mandatory redemption price for all of the Notes to be redeemed. If such deposit is made as provided above, the Notes will cease to bear
            interest on and after the special mandatory redemption date.

           

          

          
            
              


          

          
          “merger” means the merger of Baseball Merger Sub, Inc., an indirect wholly-owned subsidiary of the Company, with and into Anadarko Petroleum Corporation
            pursuant to the merger agreement.

           

          “merger agreement” means the Agreement and Plan of Merger, dated as of May 9, 2019, by and among the Company, Anadarko Petroleum Corporation and Baseball
            Merger Sub 1, Inc.

           

          The Notes are redeemable, in whole at any time or in part from time to time prior to June 15, 2026 (the “Par Call Date”), 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) as determined by the Quotation Agent, the sum of the present values of the remaining scheduled payments of principal and interest
            on the Notes to be redeemed through the Par Call Date (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 the Par Call Date, 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, as determined by the Quotation Agent, 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 that 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 to be redeemed (assuming, for this purpose, that the Notes mature on the Par Call
                        Date), 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 semi-annual 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.

                    


            

          

           

          
            2

            
              


          

          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
            mature on the Par Call Date).

           

          “Comparable Treasury Price” means, with respect to any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations for such Redemption
            Date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) 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 (3) 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, each of (1) BofA Securities, Inc. and Citigroup Global Markets Inc. (or their
            respective affiliates that 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 (2) any other Primary Treasury Dealer or Dealers selected by the Company.

           

          “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 10 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, in the case of Global Notes, in accordance with the policies and procedures of the
            depository or, in the case of Definitive Notes, by the Trustee by such method as the Trustee shall deem fair and appropriate, all as more fully provided in the Indenture.

           

          
            3

            
              


          

          All notices of redemption shall state the Redemption Date, the Redemption Price (or, if not then ascertainable, the manner of calculation thereof), 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 an 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 (i) the Holders of not less than a majority in principal amount of the Outstanding Securities of all series voting as a single class or (ii) if fewer than all of the series of the
            Outstanding Securities are affected by such addition, change, elimination, or modification, the Holders of not less than a majority in principal amount of the Outstanding Securities of all series so affected voting as a single class (including,
            for the avoidance of doubt, consents obtained in connection with a purchase of, or tender offer or exchange for, such debt securities). The Indenture also contains provisions permitting the Holders of not less than a majority in aggregate
            principal amount of the Outstanding Securities of any series, on behalf of the Holders of all Outstanding 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 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.

           

          
            4

            
              


          

          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), TENENT (=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).

           

          All undefined terms (whether or not capitalized) used in this Note which are defined in the Indenture shall have the meanings assigned to them in the Indenture.

          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 CEDE & CO., 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 August
            8, 2019 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 February 15, 2020, 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 appointed co-authenticating agent by manual signature, this Note shall not be entitled to any
            benefit under the Indenture or be valid or obligatory for any purpose.

          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 3.500% Senior Notes due 2029 (the “Notes”), limited in initial aggregate principal amount to $1,500,000,000. 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 8, 2019 (herein called the “Indenture” which term, for the purpose of this
            Note, shall include the Officer’s Certificate dated August 8, 2019, 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 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 the Notes and issue additional Notes.

           

          If (i) the merger has not been completed on or prior to May 14, 2020, or (ii) at any time prior to May 14, 2020, the merger agreement has been validly terminated (other than in connection with
            the consummation of the merger) (the earlier to occur of the events described in clause (i) or (ii), the “special mandatory redemption event”), the Company shall be required to redeem all of the Notes on
            the special mandatory redemption date (as defined below) at a redemption price (the “special mandatory redemption price”) equal to 101% of the principal amount of the Notes, plus accrued and unpaid
            interest, if any, to, but excluding, the special mandatory redemption date. Upon the occurrence of a special mandatory redemption event, the Company shall promptly (but in no event later than ten Business Days following such special mandatory
            redemption event) cause notice (a “special mandatory redemption notice”) to be delivered electronically or mailed, with a copy to the Trustee, to each Holder at its registered address (such date of
            notification to the Holders, the “special mandatory redemption notice date”). The notice will inform Holders that the Notes will be redeemed on the redemption date set forth in such notice, which will be
            no earlier than three Business Days and no later than 60 days from the special mandatory redemption notice date (such date, the “special mandatory redemption date”), and that all of the outstanding Notes
            will be redeemed at the special mandatory redemption price on the special mandatory redemption date automatically and without any further action by the Holders of the Notes. At or prior to 10:00 a.m., New York City time, on the special
            mandatory redemption date, the Company shall deposit with the Trustee funds sufficient to pay the special mandatory redemption price for all of the Notes to be redeemed. If such deposit is made as provided above, the Notes will cease to bear
            interest on and after the special mandatory redemption date.

           

          
            
              


          

          
          “merger” means the merger of Baseball Merger Sub, Inc., an indirect wholly-owned subsidiary of the Company, with and into Anadarko Petroleum Corporation
            pursuant to the merger agreement.

           

          “merger agreement” means the Agreement and Plan of Merger, dated as of May 9, 2019, by and among the Company, Anadarko Petroleum Corporation and Baseball
            Merger Sub 1, Inc.

           

          The Notes are redeemable, in whole at any time or in part from time to time prior to May 15, 2029 (the “Par Call Date”), 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) as determined by the Quotation Agent, the sum of the present values of the remaining scheduled payments of principal and interest
            on the Notes to be redeemed through the Par Call Date (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 30 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 the Par Call Date, 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, as determined by the Quotation Agent, 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 that 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 to be redeemed (assuming, for this purpose, that the Notes mature on the Par Call
                        Date), 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 semi-annual 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.

                    


            

          

           

          
            2

            
              


          

          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
            mature on the Par Call Date).

           

          “Comparable Treasury Price” means, with respect to any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations for such Redemption
            Date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) 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 (3) 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, each of (1) BofA Securities, Inc. and Citigroup Global Markets Inc. (or their
            respective affiliates that 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 (2) any other Primary Treasury Dealer or Dealers selected by the Company.

           

          “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 10 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, in the case of Global Notes, in accordance with the policies and procedures of the
            depository or, in the case of Definitive Notes, by the Trustee by such method as the Trustee shall deem fair and appropriate, all as more fully provided in the Indenture.

           

          
            3

            
              


          

          All notices of redemption shall state the Redemption Date, the Redemption Price (or, if not then ascertainable, the manner of calculation thereof), 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 an 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 (i) the Holders of not less than a majority in principal amount of the Outstanding Securities of all series voting as a single class or (ii) if fewer than all of the series of the
            Outstanding Securities are affected by such addition, change, elimination, or modification, the Holders of not less than a majority in principal amount of the Outstanding Securities of all series so affected voting as a single class (including,
            for the avoidance of doubt, consents obtained in connection with a purchase of, or tender offer or exchange for, such debt securities). The Indenture also contains provisions permitting the Holders of not less than a majority in aggregate
            principal amount of the Outstanding Securities of any series, on behalf of the Holders of all Outstanding 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 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.

           

          
            4

            
              


          

          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), TENENT (=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).

           

          All undefined terms (whether or not capitalized) used in this Note which are defined in the Indenture shall have the meanings assigned to them in the Indenture.

          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 CEDE & CO., 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 August
            8, 2019 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 February 15, 2020, 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 appointed co-authenticating agent by manual signature, this Note shall not be entitled to any
            benefit under the Indenture or be valid or obligatory for any purpose.

          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 4.300% Senior Notes due 2039 (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 8, 2019 (herein called the “Indenture” which term, for the purpose of this
            Note, shall include the Officer’s Certificate dated August 8, 2019, 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 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 the Notes and issue additional Notes.

           

          If (i) the merger has not been completed on or prior to May 14, 2020, or (ii) at any time prior to May 14, 2020, the merger agreement has been validly terminated (other than in connection with
            the consummation of the merger) (the earlier to occur of the events described in clause (i) or (ii), the “special mandatory redemption event”), the Company shall be required to redeem all of the Notes on
            the special mandatory redemption date (as defined below) at a redemption price (the “special mandatory redemption price”) equal to 101% of the principal amount of the Notes, plus accrued and unpaid
            interest, if any, to, but excluding, the special mandatory redemption date. Upon the occurrence of a special mandatory redemption event, the Company shall promptly (but in no event later than ten Business Days following such special mandatory
            redemption event) cause notice (a “special mandatory redemption notice”) to be delivered electronically or mailed, with a copy to the Trustee, to each Holder at its registered address (such date of
            notification to the Holders, the “special mandatory redemption notice date”). The notice will inform Holders that the Notes will be redeemed on the redemption date set forth in such notice, which will be
            no earlier than three Business Days and no later than 60 days from the special mandatory redemption notice date (such date, the “special mandatory redemption date”), and that all of the outstanding Notes
            will be redeemed at the special mandatory redemption price on the special mandatory redemption date automatically and without any further action by the Holders of the Notes. At or prior to 10:00 a.m., New York City time, on the special
            mandatory redemption date, the Company shall deposit with the Trustee funds sufficient to pay the special mandatory redemption price for all of the Notes to be redeemed. If such deposit is made as provided above, the Notes will cease to bear
            interest on and after the special mandatory redemption date.

           

          
            
              


          

          
          “merger” means the merger of Baseball Merger Sub, Inc., an indirect wholly-owned subsidiary of the Company, with and into Anadarko Petroleum Corporation
            pursuant to the merger agreement.

           

          “merger agreement” means the Agreement and Plan of Merger, dated as of May 9, 2019, by and among the Company, Anadarko Petroleum Corporation and Baseball
            Merger Sub 1, Inc.

           

          The Notes are redeemable, in whole at any time or in part from time to time prior to February 15, 2039 (the “Par Call Date”), 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) as determined by the Quotation Agent, the sum of the present values of the remaining scheduled payments of principal and
            interest on the Notes to be redeemed through the Par Call Date (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 35 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 the Par Call Date, 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, as determined by the Quotation Agent, 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 that 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 to be redeemed (assuming, for this purpose, that the Notes mature on the Par Call
                        Date), 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 semi-annual 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.

                    


            

          

           

          
            2

            
              


          

          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
            mature on the Par Call Date).

           

          “Comparable Treasury Price” means, with respect to any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations for such Redemption
            Date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) 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 (3) 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, each of (1) BofA Securities, Inc. and Citigroup Global Markets Inc. (or their
            respective affiliates that 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 (2) any other Primary Treasury Dealer or Dealers selected by the Company.

           

          “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 10 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, in the case of Global Notes, in accordance with the policies and procedures of the
            depository or, in the case of Definitive Notes, by the Trustee by such method as the Trustee shall deem fair and appropriate, all as more fully provided in the Indenture.

           

          
            3

            
              


          

          All notices of redemption shall state the Redemption Date, the Redemption Price (or, if not then ascertainable, the manner of calculation thereof), 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 an 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 (i) the Holders of not less than a majority in principal amount of the Outstanding Securities of all series voting as a single class or (ii) if fewer than all of the series of the
            Outstanding Securities are affected by such addition, change, elimination, or modification, the Holders of not less than a majority in principal amount of the Outstanding Securities of all series so affected voting as a single class (including,
            for the avoidance of doubt, consents obtained in connection with a purchase of, or tender offer or exchange for, such debt securities). The Indenture also contains provisions permitting the Holders of not less than a majority in aggregate
            principal amount of the Outstanding Securities of any series, on behalf of the Holders of all Outstanding 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 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

          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).

          All undefined terms (whether or not capitalized) used in this Note which are defined in the Indenture shall have the meanings assigned to them in the Indenture.

            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 CEDE & CO., 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 August
              8, 2019 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 February 15, 2020, 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 appointed co-authenticating agent by manual signature, this Note shall not be entitled to any
              benefit under the Indenture or be valid or obligatory for any purpose.

            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 4.400% Senior Notes due 2049 (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 8, 2019 (herein called the “Indenture” which term, for the purpose of this
              Note, shall include the Officer’s Certificate dated August 8, 2019, 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 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 the Notes and issue additional Notes.

             

            If (i) the merger has not been completed on or prior to May 14, 2020, or (ii) at any time prior to May 14, 2020, the merger agreement has been validly terminated (other than in connection
              with the consummation of the merger) (the earlier to occur of the events described in clause (i) or (ii), the “special mandatory redemption event”), the Company shall be required to redeem all of the
              Notes on the special mandatory redemption date (as defined below) at a redemption price (the “special mandatory redemption price”) equal to 101% of the principal amount of the Notes, plus accrued and
              unpaid interest, if any, to, but excluding, the special mandatory redemption date. Upon the occurrence of a special mandatory redemption event, the Company shall promptly (but in no event later than ten Business Days following such special
              mandatory redemption event) cause notice (a “special mandatory redemption notice”) to be delivered electronically or mailed, with a copy to the Trustee, to each Holder at its registered address (such
              date of notification to the Holders, the “special mandatory redemption notice date”). The notice will inform Holders that the Notes will be redeemed on the redemption date set forth in such notice,
              which will be no earlier than three Business Days and no later than 60 days from the special mandatory redemption notice date (such date, the “special mandatory redemption date”), and that all of the
              outstanding Notes will be redeemed at the special mandatory redemption price on the special mandatory redemption date automatically and without any further action by the Holders of the Notes. At or prior to 10:00 a.m., New York City time, on
              the special mandatory redemption date, the Company shall deposit with the Trustee funds sufficient to pay the special mandatory redemption price for all of the Notes to be redeemed. If such deposit is made as provided above, the Notes will
              cease to bear interest on and after the special mandatory redemption date.

             

            
              
                


            

            
            “merger” means the merger of Baseball Merger Sub, Inc., an indirect wholly-owned subsidiary of the Company, with and into Anadarko Petroleum

              Baseball Merger Sub 1, Inc.

             

            The Notes are redeemable, in whole at any time or in part from time to time prior to February 15, 2049 (the “Par Call Date”), 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) as determined by the Quotation Agent, the sum of the present values of the remaining scheduled payments of principal
              and interest on the Notes to be redeemed through the Par Call Date (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 35 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 the Par Call Date, 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, as determined by the Quotation Agent, 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 that 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 to be redeemed (assuming, for this purpose, that the Notes mature on the
                          Par Call Date), 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 semi-annual 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.

                      


              

            

             

            
              2

              
                


            

            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 mature on the Par Call Date).

             

            “Comparable Treasury Price” means, with respect to any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations for such Redemption
              Date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) 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 (3) 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, each of (1) BofA Securities, Inc. and Citigroup Global Markets Inc. (or their
              respective affiliates that 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 (2) any other Primary Treasury Dealer or Dealers selected by the Company.

             

            “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 10 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, in the case of Global Notes, in accordance with the policies and procedures of the
              depository or, in the case of Definitive Notes, by the Trustee by such method as the Trustee shall deem fair and appropriate, all as more fully provided in the Indenture.

             

            
              3

              
                


            

            All notices of redemption shall state the Redemption Date, the Redemption Price (or, if not then ascertainable, the manner of calculation thereof), 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 an 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 (i) the Holders of not less than a majority in principal amount of the Outstanding Securities of all series voting as a single class or (ii) if fewer than all of the series of the
              Outstanding Securities are affected by such addition, change, elimination, or modification, the Holders of not less than a majority in principal amount of the Outstanding Securities of all series so affected voting as a single class
              (including, for the avoidance of doubt, consents obtained in connection with a purchase of, or tender offer or exchange for, such debt securities). The Indenture also contains provisions permitting the Holders of not less than a majority in
              aggregate principal amount of the Outstanding Securities of any series, on behalf of the Holders of all Outstanding 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 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.

             

            
              4

              
                


            

            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), TENENT (=tenants by the entireties), JT TEN (=joint tenants with right of
