TRUSTEE'S CERTIFICATE OF AUTHENTICATION    
  

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

	The Bank of New York, as Trustee	 	 
	 	 	 	 	 
	By:	 	 	 	 
	 	 	
 Authorized Signatory	 	 

    Occidental Petroleum Corporation, a corporation duly organized and existing under the laws of the State of Delaware (herein referred to as the "Company"), for value received, hereby
promises to pay to
CEDE & CO., or registered assigns, the Principal Amount specified above on the Maturity Date specified above (unless and to the extent earlier redeemed or repaid prior to such Maturity Date)
and to pay interest thereon from December 6, 2001 or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semiannually in arrears on
January 15 and July 15, in each year, commencing on July 15, 2002, at the rate per annum specified above, until the principal hereof is paid or made available for payment.
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 (as defined below), 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 January 1 or July 1 (whether or not a Business Day), as the case may be, next 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 at Maturity will be made on the following day that is a Business Day as
if it were made on the date such payment was due 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. Except
as otherwise provided in the Indenture, any interest not punctually paid or duly provided for on any Interest Payment Date (herein called "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
shall 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, if any, on this Note will be made at the Corporate Trust Office of the Trustee or at the office or agency of the Trustee maintained for that purpose in the Borough of Manhattan, The City of
New York, and at any other office or agency maintained 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, however, that, at the option of the Company, payment of interest may be made by check mailed to the address of
the Person entitled thereto as such address shall appear in the Security Register; and provided, further, that the Holder of this Note shall be entitled
to receive payments of principal of and interest, if any, on this Note 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 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 (which term includes any successor corporation under the Indenture
hereinafter referred to) issued and to be issued pursuant to such Indenture. This Note is one of a series designated by the Company as its 5.875% Senior Notes due January 15, 2007 (the
"Notes"), limited in initial aggregate
principal amount to $300,000,000. The Indenture does not limit the aggregate principal amount of the Securities. 

    The
Company issued this Note pursuant to an Indenture, dated as of April 1, 1998 (herein called the "Indenture" which term, for the purpose of this Note, shall include the
Officers' Certificate dated November 29, 2001, delivered pursuant to Sections 201 and 301 of the Indenture), between the Company and The Bank of New York, as trustee (herein called the
"Trustee," which term includes any 

successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and
immunities thereunder of the Company, the Trustee and Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered. 

    The
Notes are issuable as Registered Securities, without coupons, in denominations of $1,000 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, Notes are exchangeable for a like aggregate principal amount of Notes of like tenor of any authorized denomination, as requested by
the Holder surrendering the same, upon surrender of the Note or Notes to be exchanged at any office or agency described below where Notes may be presented for registration of transfer. 

    The
Company may, from time to time, without notice to or the consent of the Holders of the Notes, reopen this series of Notes and issue additional Notes. 

    The
Notes are redeemable, in whole or in part, at the option of the Company at any time at a redemption price equal to the greater of (i) 100% of the principal amount of the
Notes and (ii) an amount (determined by the Quotation Agent (as defined herein)) equal to the sum of the present values of the remaining scheduled payments of principal and interest on the
Notes (not including any portion of such payments of interest accrued as of the date of the redemption) discounted to the date of redemption on a semiannual basis (assuming a 360-day year
consisting of twelve 30-day months) at the Adjusted Treasury Rate (as defined herein) plus 30 basis points plus, in each case, accrued interest thereon to the date of redemption. 

    "Adjusted
Treasury Rate" means, with respect to any redemption date, the rate per annum equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming
a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date. 

    "Comparable
Treasury Issue" means the United States Treasury security selected by the Quotation Agent as having a maturity comparable to the remaining term of the Notes 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, (i) the average of the Reference Treasury Dealer Quotations for such redemption date, after excluding
the highest and lowest Reference Treasury Dealer Quotations, or (ii) if the Trustee obtains fewer than three Reference Treasury Dealer Quotations, the average of all such Reference Treasury
Dealer Quotations, such average in any case to be determined by the Quotation Agent, or (iii) if only one Reference Treasury Dealer Quotation is received, such Reference Treasury Dealer
Quotation. 

    "Quotation
Agent" means the Reference Treasury Dealer appointed by the Company. 

    "Reference
Treasury Dealer" means (i) Banc of America Securities LLC and J.P. Morgan Securities Inc. (or their respective affiliates which are primary U.S. Government
securities dealers) and their respective successors; provided, however, that if either of the foregoing shall cease to be a primary U.S. Government
securities dealer in New York City (a "Primary Treasury Dealer"), the Company shall substitute therefor another Primary Treasury Dealer, and (ii) any other Primary Treasury Dealer(s) 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 Trustee by such Reference Treasury Dealer at 5:00 p.m.
on the third Business Day in The City of New York preceding such redemption date. 

    Notice
of any redemption will be mailed at least 30 days but not more than 60 days before the redemption date to each Holder of the Notes to be redeemed. Unless the
Company defaults in payment of the redemption price, on and after the redemption date, interest will cease to accrue on the 

Notes or portions thereof called for redemption. If less than all of the Notes are to be redeemed, the Notes (or portions thereof) to be redeemed shall be selected by the Trustee by such method as the
Trustee shall deem fair and appropriate. 

    Notwithstanding
the foregoing, installments of interest whose Stated Maturity is prior to the Redemption Date of any Note will be payable to the Holder of such Note, or one or more
Predecessor
Securities, of record at the close of business on the relevant Regular Record Date referred to above, all as provided in the Indenture. 

    All
notices of redemption shall state the Redemption Date, the Redemption Price, if fewer than all the Outstanding Notes are to be redeemed, the identification (and, in the case of
partial redemption, the principal amounts) of the particular Notes to be redeemed, that on the Redemption Date the Redemption Price will become due and payable upon each Note, or portion thereof, to
be redeemed, 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. If
fewer than all of the Notes are to be redeemed at any time, selection of such Notes for redemption will be made by the Trustee by such method as the Trustee shall deem fair and appropriate. 

    In
the event of redemption of this Note in part only, a new Note or Notes of like tenor for the unredeemed portion hereof will be issued in authorized denominations in the name of the
Holder hereof upon the cancellation 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 the Notes may be declared due and payable in the manner and with the effect provided in
the Indenture. 

    The
Indenture permits, in certain circumstances therein specified, the amendment thereof without the consent of the Holders of the Securities. The Indenture also permits, with certain
exceptions as therein provided, the amendment thereof and the modification of the rights and obligations under the Indenture of the Company and the rights of Holders of the Securities of each series
to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in aggregate principal amount of the Securities at the time Outstanding of
each series to be affected. The Indenture also contains provisions permitting the Holders of a majority in aggregate principal amount of the Securities of each series at the time Outstanding, on
behalf of the Holders of all the Securities of such series, to waive 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, 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, cash or U.S. Government Obligations with the Trustee in trust solely for the benefit of the Holders of all Outstanding Notes, to defease the Indenture
with respect to such Notes, and upon such deposit the Company shall be deemed to have paid and discharged its entire indebtedness on such Notes. Thereafter, Holders would be able to look only to such
trust fund for payment of principal and interest at the Stated Maturity or Redemption Date, as the case may be. 

    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 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 hereof 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, 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 laws of the State of New York including, without limitation, Section 5-1401 of the New York
General Obligations Law. 

    All
undefined terms used in this Note which are defined in the Indenture shall have the meanings assigned to them in the Indenture. 

    In
Witness Whereof, Occidental Petroleum Corporation has caused this Note to be signed by the signature or facsimile signature of its Chairman of the Board, its President, a Vice
President, its Treasurer or an Assistant Treasurer and attested by its Secretary or an Assistant Secretary by his or her signature or a facsimile thereof, and its corporate seal or a facsimile of its

TRUSTEE'S CERTIFICATE OF AUTHENTICATION    
  

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

The
Bank of New York, as Trustee 

	By:	 	 	 	 
	 	 	
 Authorized Signatory	 	 

    Occidental Petroleum Corporation, a corporation duly organized and existing under the laws of the State of Delaware (herein referred to as the "Company"), for value received, hereby
promises to pay to CEDE & CO., or registered assigns, the Principal Amount specified above on the Maturity Date specified above (unless and to the extent earlier redeemed or repaid prior to
such Maturity Date) and to pay interest thereon from December 6, 2001 or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semiannually in arrears
on January 15 and July 15, in each year, commencing on July 15, 2002, at the rate per annum specified above, until the principal hereof is paid or made available for payment.
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 (as defined below), 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 January 1 or July 1 (whether or not a Business Day), as the case may be, next 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 at Maturity will be made on the following day that is a Business Day as
if it were made on the date such payment was due 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. Except
as otherwise provided in the Indenture, any interest not punctually paid or duly provided for on any Interest Payment Date (herein called "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
shall 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, if any, on this Note will be made at the Corporate Trust Office of the Trustee or at the office or agency of the Trustee maintained for that purpose in the Borough of Manhattan, The City of
New York, and at any other office or agency maintained 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, however, that, at the option of the Company, payment of interest may be made by check mailed to the address of
the Person entitled thereto as such address shall appear in the Security Register; and provided, further, that the Holder of this Note shall be entitled
to receive payments of principal of and interest, if any, on this Note 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 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 (which term includes any successor corporation under the Indenture
hereinafter referred to) issued and to be issued pursuant to such Indenture. This Note is one of a series designated by the Company as its 6.750% Senior Notes due January 15, 2012 (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 April 1, 1998 (herein called the "Indenture" which term, for the purpose of this Note, shall include the
Officers' Certificate dated November 29, 2001, delivered pursuant to Sections 201 and 301 of the Indenture), between the Company and The Bank of New York, as trustee (herein called the
"Trustee," which term includes any 

successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and
immunities thereunder of the Company, the Trustee and Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered. 

    The
Notes are issuable as Registered Securities, without coupons, in denominations of $1,000 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, Notes are exchangeable for a like aggregate principal amount of Notes of like tenor of any authorized denomination, as requested by
the Holder surrendering the same, upon surrender of the Note or Notes to be exchanged at any office or agency described below where Notes may be presented for registration of transfer. 

    The
Company may, from time to time, without notice to or the consent of the Holders of the Notes, reopen this series of Notes and issue additional Notes. 

    The
Notes are redeemable, in whole or in part, at the option of the Company at any time at a redemption price equal to the greater of (i) 100% of the principal amount of the
Notes and (ii) an amount (determined by the Quotation Agent (as defined herein)) equal to the sum of the present values of the remaining scheduled payments of principal and interest on the
Notes (not including any portion of such payments of interest accrued as of the date of the redemption) discounted to the date of redemption on a semiannual basis (assuming a 360-day year
consisting of twelve 30-day months) at the Adjusted Treasury Rate (as defined herein) plus 35 basis points plus, in each case, accrued interest thereon to the date of redemption. 

    "Adjusted
Treasury Rate" means, with respect to any redemption date, the rate per annum equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming
a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date. 

    "Comparable
Treasury Issue" means the United States Treasury security selected by the Quotation Agent as having a maturity comparable to the remaining term of the Notes 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, (i) the average of the Reference Treasury Dealer Quotations for such redemption date, after excluding
the highest and lowest Reference Treasury Dealer Quotations, or (ii) if the Trustee obtains fewer than three Reference Treasury Dealer Quotations, the average of all such Reference Treasury
Dealer Quotations, such average in any case to be determined by the Quotation Agent, or (iii) if only one Reference Treasury Dealer Quotation is received, such Reference Treasury Dealer
Quotation. 

    "Quotation
Agent" means the Reference Treasury Dealer appointed by the Company. 

    "Reference
Treasury Dealer" means (i) Banc of America Securities LLC and J.P. Morgan Securities Inc. (or their respective affiliates which are primary U.S. Government
securities dealers) and their respective successors; provided, however, that if either of the foregoing shall cease to be a primary U.S. Government
securities dealer in New York City (a "Primary Treasury Dealer"), the Company shall substitute therefor another Primary Treasury Dealer, and (ii) any other Primary Treasury Dealer(s) 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 Trustee by such Reference Treasury Dealer at 5:00 p.m.
on the third Business Day in The City of New York preceding such redemption date. 

    Notice
of any redemption will be mailed at least 30 days but not more than 60 days before the redemption date to each Holder of the Notes to be redeemed. Unless the
Company defaults in payment of the redemption price, on and after the redemption date, interest will cease to accrue on the 

Notes or portions thereof called for redemption. If less than all of the Notes are to be redeemed, the Notes (or portions thereof) to be redeemed shall be selected by the Trustee by such method as the
Trustee shall deem fair and appropriate. 

    Notwithstanding
the foregoing, installments of interest whose Stated Maturity is prior to the Redemption Date of any Note will be payable to the Holder of such Note, or one or more
Predecessor Securities, of record at the close of business on the relevant Regular Record Date referred to above, all as provided in the Indenture. 

    All
notices of redemption shall state the Redemption Date, the Redemption Price, if fewer than all the Outstanding Notes are to be redeemed, the identification (and, in the case of
partial redemption, the principal amounts) of the particular Notes to be redeemed, that on the Redemption Date the Redemption Price will become due and payable upon each Note, or portion thereof, to
be redeemed, 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. If
fewer than all of the Notes are to be redeemed at any time, selection of such Notes for redemption will be made by the Trustee by such method as the Trustee shall deem fair and appropriate. 

    In
the event of redemption of this Note in part only, a new Note or Notes of like tenor for the unredeemed portion hereof will be issued in authorized denominations in the name of the
Holder hereof upon the cancellation 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 the Notes may be declared due and payable in the manner and with the effect provided in
the Indenture. 

    The
Indenture permits, in certain circumstances therein specified, the amendment thereof without the consent of the Holders of the Securities. The Indenture also permits, with certain
exceptions as therein provided, the amendment thereof and the modification of the rights and obligations under the Indenture of the Company and the rights of Holders of the Securities of each series
to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in aggregate principal amount of the Securities at the time Outstanding of
each series to be affected. The Indenture also contains provisions permitting the Holders of a majority in aggregate principal amount of the Securities of each series at the time Outstanding, on
behalf of the Holders of all the Securities of such series, to waive 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, 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, cash or U.S. Government Obligations with the Trustee in trust solely for the benefit of the Holders of all Outstanding Notes, to defease the Indenture
with respect to such Notes, and upon such deposit the Company shall be deemed to have paid and discharged its entire indebtedness on such Notes. Thereafter, Holders would be able to look only to such
trust fund for payment of principal and interest at the Stated Maturity or Redemption Date, as the case may be. 

    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 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 hereof 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, 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 laws of the State of New York including, without limitation, Section 5-1401 of the New York
General Obligations Law. 

    All
undefined terms used in this Note which are defined in the Indenture shall have the meanings assigned to them in the Indenture.
