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 face amount hereof, or, in the case of an Indexed Principal Note, the face amount hereof, adjusted by reference to prices, changes in prices, or differences between prices, of securities, currencies, intangibles, goods, articles or commodities or by such other objective price, economic or other measures (an "Index") as described on the face hereof or in the pricing supplement attached hereto or delivered herewith (the "principal amount" or "principal"), in the Specified Currency specified above on the Stated Maturity specified above (unless and to the extent earlier redeemed or repaid prior to such Stated Maturity) and to pay interest on the principal amount then outstanding at the Interest Rate shown above from the Original Issue Date specified above or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually in arrears on and , in each year, commencing with the first Interest Payment Date next succeeding the Original Issue Date, at the rate per annum set forth above, until the principal amount hereof is paid or made available for payment; provided, however, that if the Original Issue Date of this Note is between a Regular Record Date (as defined below) and the related Interest Payment Date, the first payment of interest on this Note will be made on the Interest Payment Date immediately following the next succeeding Regular Record Date to the registered Holder on such next succeeding Regular Record Date. 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 fifteenth calendar day (whether or not a Business Day), as the case may be (each a "Regular Record Date"), next preceding such Interest Payment Date; provided, however, that interest payable at the Stated Maturity or earlier redemption or repayment of this Note (the "Maturity") shall be payable to the Person to whom principal shall be payable. 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 other than at Maturity (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 (l) 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), written notice of which shall be given to the Holder of this Note by the Company not less than 10 calendar 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 in the Borough of Manhattan, The City of New York, or at any other place designated by the Company for such purpose, and, if the Specified Currency is U.S. dollars, 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, if the Holder hereof is the Holder of U.S. $1,000,000 (or the equivalent thereof in a currency other than U.S. dollars determined as provided on the reverse hereof) or more in aggregate principal amount of Notes having the same Interest Payment Dates, at the option of the Company, such U.S. dollar interest payments will be made 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. Any wire instructions received by the Trustee shall remain in effect until revoked by the Holder. Simultaneously with any election by the Holder hereof to receive payments in respect hereof in the Specified Currency (if other than U.S. dollars), such Holder shall provide appropriate wire transfer instructions to the Trustee and all such payments will be made by wire transfer of immediately available funds to an account maintained by the payee with a bank located outside the United States.

For purposes of this Note, "Business Day" means any day, other than a Saturday or Sunday, that is neither a legal holiday nor a day on which commercial banks are authorized or required by law, regulation or executive order to close in The City of New York; provided, however, that, with respect to foreign currency Notes, the day is also not a day on which commercial banks are authorized or required by law, regulation or executive order to close in the Principal Financial Center (as defined below) of the country issuing the Specified Currency or, if the Specified Currency is euros, the day is also a day on which the Trans-European Automated Real-Time Gross Settlement Express Transfer (TARGET) System is open.

[The indebtedness evidenced by this Note is, to the extent set forth in the Indenture, expressly subordinated and subject in right of payment to the prior payment in full of Senior Indebtedness as defined in the Indenture, and this Note is issued subject to such provisions, and each Holder of this Note, by accepting the same, agrees to and shall be bound by such provisions and authorizes and directs the Trustee in such Holder's behalf to take such action as may be necessary or appropriate to acknowledge or effectuate the subordination as provided in the Indenture and appoints the Trustee as such Holder's attorney-in-fact for any and all such purposes.]

If this Note is an Amortizing Note as shown on the face hereof or in the pricing supplement attached hereto or delivered herewith, a portion or all the principal amount of the Note is payable prior to Stated Maturity in accordance with a schedule, by application of a formula, or by reference to an index (as described above).

and forwarded by the depositary to the Paying Agent, on or before the relevant dates, the beneficial owner of this Note will receive payments in the Specified Currency. Such election will remain in effect until revoked by written notice to the Trustee received not later than fifteen calendar days prior to the applicable payment date. If the Company determines that the Specified Currency is not available for making payments in respect hereof due to the imposition of exchange controls or other circumstances beyond the Company's control or is no longer used by the government of the country issuing such currency or for the settlement of transactions by public institutions or within the international banking community, then the Holder hereof may not so elect to receive payments in the Specified Currency, and any such outstanding election shall be automatically suspended, and payments shall be in U.S. dollars, until the Company determines that the Specified Currency is again available for making such payments.

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.

Notwithstanding the foregoing, if an Addendum is attached hereto as specified above, this Note shall be subject to the terms set forth in such Addendum.

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 Security is one of a series designated by the Company as its Medium-Term [Senior] [Subordinated] Notes, Series [C] [A] (the "Notes"). The Indenture does not limit the aggregate principal amount of the Notes or the Securities.

The Company issued this Note pursuant to an Indenture, dated as of [April l, 1998] [January 20, 1999] (herein called the "Indenture" which term, for the purpose of this Note, shall include the Officers' Certificate dated June 30, 1999, delivered pursuant to Sections 201 and 301 of the Indenture, and the First Supplemental Indenture dated March 6, 2002), 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 U.S. dollar equivalent of the public offering price or purchase price of Notes denominated in currencies other than U.S. dollars will be determined by The Bank of New York, as exchange rate agent for the Notes (the "Exchange Rate Agent") pursuant to the Exchange Rate Agency Agreement, dated as of March 6, 2002, between the Company and the Exchange Rate Agent.

The Notes are issuable as Registered Securities, without coupons, in denominations of $1,000 (if the Specified Currency is U.S. Dollars) and any amount in excess thereof which is an integral multiple of $1,000 (if the Specified Currency is U.S. Dollars). 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.

This Note will bear interest at the rate per annum stated on the face hereof or in an addendum hereto or delivered herewith until the principal amount hereof is paid or made available for payment, except as otherwise described below under "Subsequent Interest Periods" and "Extension of Maturity," and except that if so specified in an addendum hereto, the rate of interest payable on certain Fixed Rate Notes may be subject to adjustment as specified therein. Interest on this Note will be computed on the basis of a 360-day year of twelve 30-day months.

If so specified on the face hereof or in an addendum hereto, the Interest Rate on this Note may be reset by the Company on the date or dates specified on the face hereof or in an addendum hereto or delivered herewith (each an "Optional Reset Date"). Not later than 40 days prior to each Optional Reset Date, the Trustee will mail to the Holder of this Note a notice (the "Reset Notice"), first class, postage prepaid, indicating whether the Company has elected to reset the Interest Rate, and if so, (i) such new Interest Rate and (ii) the provisions, if any, for redemption during the period from such Optional Reset Date to the next Optional Reset Date, or, if there is no such next Optional Reset Date, to the Stated Maturity of this Note (each such period, a "Subsequent Interest Period"), including the date or dates on which or the period or periods during which and the price or prices at which such redemption may occur during the Subsequent Interest Period. Upon the transmittal by the Trustee of a Reset Notice to the holder of a Note, such new interest rate shall take effect automatically. Except as modified by the Reset Notice and as described below, such Note will have the same terms as prior to the transmittal of such Reset Notice. Notwithstanding the foregoing, not later than 20 days prior to an Optional Reset Date, the Company may, at its option, revoke the Interest Rate provided for in the Reset Notice and establish a higher Interest Rate for the Subsequent Interest Period by causing the Trustee to mail notice of such higher Interest Rate to the Holder of this Note. Such notice shall be irrevocable. All Notes with respect to which the Interest Rate is reset on an Optional Reset Date will bear such higher Interest Rate whether or not tendered for repayment.

The Holder of this Note will have the option to elect repayment by the Company on each Optional Reset Date at a price equal to the principal amount hereof, plus interest accrued to such Optional Reset Date. In order to obtain repayment on an Optional Reset Date, the Holder must follow the procedures set forth below for optional repayment, except that the period for delivery or notification to the Trustee shall be at least 25 but not more than 35 days prior to such Optional Reset Date, and except that if the Holder has tendered this Note for repayment pursuant to a Reset Notice, the Holder may, by written notice to the Trustee, revoke such tender for repayment until the close of business on the tenth day before the Optional Reset Date.

If this Note is an Indexed Principal Note, then the principal amount payable at Stated Maturity or earlier redemption or retirement, is determined by reference to the amount designated on the face hereof or in an addendum hereto as the face amount of this Note and by reference to the Index as described on the face hereof or in an addendum hereto. If this Note is an Indexed Principal Note, the principal amount payable at Stated Maturity or any earlier redemption or repayment of this Note may be different from the face amount.

If a third party is appointed to calculate or announce the Index for a particular Indexed Principal Note and this third party either suspends the calculation or announcement of such Index or changes the basis upon which such Index is calculated, in a manner that is inconsistent with the applicable pricing supplement, then the Company will select another third party to calculate or announce the

Index. The agents or their respective affiliates may be either the original or successor third party selected by the Company.

If for any reason such Index cannot be calculated on the same basis and subject to the same conditions and controls as applied to the original third party, then the indexed principal amount of such Indexed Principal Note will be calculated in the manner set forth in the applicable pricing supplement. Any determination by the selected third party will be binding on all parties, except in the case of an obvious error.

If the Specified Currency is other than U.S. dollars, the amount of any U.S. dollar payment to be made in respect hereof will be determined by the Company or its agent based on the highest firm bid quotation expressed in U.S. dollars received by the Company or its agent at approximately 11:00 a.m., New York City time, on the second Business Day preceding the applicable payment date (or, if no such rate is quoted on such date, the last date on which such rate was quoted) from three (or, if three are not available, then two) recognized foreign exchange dealers in The City of New York selected by the Exchange Rate Agent (one or more of which may be an agent involved in the distribution of the Notes (an "Agent") and another of which may be the Exchange Rate Agent) for the purchase by the quoting dealer, for settlement on such payment date, of the aggregate amount of the Specified Currency payable on such payment date in respect of all Notes denominated in such Specified Currency. All currency exchange costs will be borne by the Holders of such Notes by deductions from such payments. If no such bid quotations are available, then such payments will be made in the Specified Currency, unless the Specified Currency is unavailable due to the imposition of exchange controls or to other circumstances beyond the Company's control, in which case payment will be made as described in the next paragraph.

Except as set forth below, if any payment in respect hereof is required to be made in a Specified Currency other than U.S. dollars and such currency is (i) unavailable due to the imposition of exchange controls or other circumstances beyond the Company's control, (ii) is no longer used by the government of the country issuing such currency or (iii) is no longer used for the settlement of transactions by public institutions of or within the international banking community, then such payment shall be made in U.S. dollars until such currency is again available or so used. The amount so payable on any date in such foreign currency shall be converted into U.S. dollars on the basis of the noon buying rate in New York City for cable transfers, in the Specified Currency, as certified for customs purposes by the Federal Reserve Bank of New York (the "Market Exchange Rate") as of the second Business Day preceding that day, or if such Market Exchange Rate is unavailable, the most recently available Market Exchange Rate for such currency, or as otherwise indicated on the face hereof or in the pricing supplement attached hereto or delivered herewith. Any payment made under such circumstances in U.S. dollars will not constitute an Event of Default under the Indenture.

In the event of an official redenomination of the Specified Currency of this Note (other than as a result of the European Monetary Union, but including, without limitation, an official redenomination of any such Specified Currency that is a composite currency), the obligations of the Company with respect to payments on this Note shall, in all cases, be deemed immediately following such redenomination to provide for the payment of that amount of redenominated currency representing the amount of such obligations immediately before such redenomination. This Note does not provide for any adjustment to any amount payable under this Note as a result of (i) any change in the value of the Specified Currency hereof relative to any other currency due solely to fluctuations in exchange rates or (ii) any redenomination of any component currency of any composite currency (unless such composite currency is itself officially redenominated).

If this Note is specified on the face hereof or in an addendum hereto as a Dual Currency Note, the Company may have a one time option, exercisable on one or more dates (each an "Option Election Date"), with respect to all Dual Currency Notes issued on the same day and having the same terms (a "Tranche"), of thereafter making all payments of principal, premium, if any, and interest (which payments would otherwise be made in the Specified Currency of such Notes) in an optional currency (the "Optional Payment Currency"). Such option will be exercisable in whole but not in part on an Option Election Date, which will be any one of the dates specified on the face hereof or in an addendum hereto.

If the Company makes such an election, the amount payable in the Optional Payment Currency shall be determined using the Designated Exchange Rate specified on the face hereof or in an addendum hereto. If such election is made, notice of such election shall be mailed in accordance with the terms of the applicable Tranche of Dual Currency Notes within two Business Days of the Option Election Date and shall state (i) the first date, whether an Interest Payment Date and/or Stated Maturity, on which scheduled payments in the Optional Payment Currency will be made and (ii) the Designated Exchange Rate. Any such notice by the Company, once given, may not be withdrawn. The equivalent value in the Specified Currency of payments made after such an election may be less, at the then current exchange rate, than if the Company had made such payment in the Specified Currency.

If this Note is specified on the face hereof or in an addendum hereto as a Renewable Note, this Note will mature on an Interest Payment Date occurring in or prior to the twelfth month following the Original Issue Date of this Note (the "Initial Stated Maturity") unless the term of all or any portion of this Note is renewed in accordance with the following procedures.

On the Interest Payment Date occurring in the sixth month (unless a different interval (the "Special Election Interval") is specified on the face hereof or in the pricing supplement attached hereto or delivered herewith) prior to the Initial Stated Maturity of this Note (the "Initial Renewal Date") and on the Interest Payment Date occurring in each sixth month (or in the last month of each Special Election Interval) after such Initial Renewal Date (each, together with the Initial Renewal Date, a "Renewal Date"), the term of this Note may be extended to the Interest Payment Date occurring in the twelfth month (or, if a Special Election Interval is specified on the face hereof or in the pricing supplement attached hereto or delivered herewith, the last month in a period equal to twice the Special Election Interval) after such Renewal Date, if the Holder of this Note elects to extend the term of this Note or any portion thereof as described below. If the Holder does not elect to extend the term of any portion of the principal amount of this Note during the specified period prior to any Renewal Date, such portion will become due and payable on the Interest Payment Date occurring in the sixth month (or the last month in the Special Election Interval) after such Renewal Date (the "New Maturity Date").

The Holder may elect to renew the term of this Note, or if so specified, any portion thereof, by delivering a notice to such effect to the Trustee (or any duly appointed paying agent) at the corporate trust office of the Trustee or agency of the Trustee in the City of New York not less than 15 nor more than 30 days prior to such Renewal Date. Such election will be irrevocable and will be binding upon each subsequent Holder of this Note. An election to renew the term of this Note may be exercised with respect to less than the entire principal amount of this Note only if so specified on the face hereof or in an addendum hereto and then only in such principal amount, or any integral multiple in excess of such amount, as is specified on the face hereof or in the pricing supplement attached hereto or delivered herewith. Notwithstanding the foregoing, the term of this Note may not be extended beyond the Stated Maturity specified for this Note on the face hereof or in an addendum hereto.

If the Holder does not elect to renew the term, this Note must be presented to the Trustee (or any duly appointed paying agent) and, as soon as practicable following receipt of such Note the Trustee (or any duly appointed paying agent) shall issue in exchange therefor in the name of such Holder (i) a Note, in a principal amount equal to the principal amount of such exchanged Note for which no election to renew the term thereof was exercised, with terms identical to those specified on such exchanged Note (except that such Note shall have a fixed, nonrenewable Stated Maturity on the New Maturity Date) and (ii) if an election to renew is made with respect to less than the full principal amount of such Holder's Note, the Trustee, or any duly appointed paying agent, shall issue in exchange for such Note in the name of such Holder, a replacement Renewable Note, in a principal amount equal to the principal amount of such exchanged Note for which the election to renew was made, with terms otherwise identical to the exchanged Note.

If so specified on the face hereof or in an addendum hereto, the Maturity of this Note may be extended at the option of the Company for one or more periods of whole years specified on the face hereof or in the pricing supplement attached hereto or delivered herewith (each an "Extension Period") from one to five, up to but not beyond the date (the "Final Maturity") set forth on the face hereof or in an addendum hereto. The Company may exercise such option by notifying the Trustee for this Note at least 45 but not more than 60 days prior to the old Stated Maturity of this Note. If the Company exercises such option, the Trustee will mail to the Holder of this Note not later than 40 days prior to the old Stated Maturity a notice (the "Extension Notice") first class, postage prepaid indicating (i) the election of the Company to extend the Stated Maturity, (ii) the new Stated Maturity, (iii) the Interest Rate applicable to the Extension Period and (iv) the provisions, if any, for redemption during such Extension Period including the date or dates on which, or the period or periods during which, and the price or prices at which such redemption may occur during the extension period.

Upon the Trustee's mailing of the Extension Notice, the Stated Maturity of this Note shall be extended automatically and, except as modified by the Extension Notice and as described in the next paragraph, this Note will have the same terms as prior to the mailing of such Extension Notice. Notwithstanding the foregoing, not later than 20 days prior to the old Stated Maturity of this Note, the Company may, at its option, revoke the Interest Rate provided for in the Extension Notice and establish a higher Interest Rate for the Extension Period by causing the Trustee to mail notice of such higher Interest Rate, first class, postage prepaid to the Holder of this Note. Such notice shall be irrevocable. All Notes with respect to which the Stated Maturity is extended will bear such higher Interest Rate for the extension period, whether or not tendered for repayment.

If the Company extends the Stated Maturity of this Note, the Holder will have the option to elect repayment of this Note by the Company on the old Stated Maturity at a price equal to the principal amount hereof, plus interest accrued to such date. In order to obtain repayment on such old Stated Maturity once the Company has extended the Stated Maturity hereof, the Holder must follow the procedures set forth below for optional repayment, except that the period for delivery of this Note or notification to the Trustee shall be at least 25 but not more than 35 days before the old Stated Maturity, and except that if the Holder has tendered this Note for repayment pursuant to an Extension Notice, the Holder may, by written notice to the Trustee, revoke such tender for repayment until the close of business on the tenth day before the old Stated Maturity.

dollars) (provided that any remaining principal amount hereof shall be an Authorized Denomination and at least the minimum Authorized Denomination hereof) at the Redemption Price (as defined below), together with unpaid interest accrued thereon to the date fixed for redemption (the "Redemption Date"), on written notice given to the Holder hereof (in accordance with the provisions of the Indenture) not more than 60 nor less than 30 calendar days prior to the Redemption Date. The "Redemption Price" shall be the Initial Redemption Percentage specified on the face hereof (as adjusted by the Annual Redemption Percentage Reduction, if any, specified on the face hereof as set forth below) multiplied by the unpaid principal amount of this Note to be redeemed. The Initial Redemption Percentage, if any, shall decline at each anniversary of the Initial Redemption Date by the Annual Redemption Percentage Reduction, if any, until the Redemption Price is equal to 100% of the unpaid principal amount to be redeemed. Whenever less than all of the Notes of like tenor and terms are to be redeemed, the Notes to be redeemed and the Holders thereof shall be selected by the Trustee by such method as the Trustee shall deem fair and reasonable. In the event of redemption of this Note in part only, a new Note of like tenor and otherwise having the same terms as this Note for the unredeemed portion hereof shall be issued by the Company in the name of the Holder hereof, without charge, upon the presentation and surrender hereof.

This Note will be subject to repayment by the Company at the option of the Holder hereof on the Optional Repayment Date(s), if any, specified on the face hereof, in whole or from time to time in part in increments of U.S.$l,000 (if the Specified Currency is U.S. dollars) or such other increment specified on the face hereof under Authorized Denomination (if the Specified Currency is not U.S. dollars) (provided that any remaining principal amount hereof shall be an Authorized Denomination and at least the minimum Authorized Denomination hereof) at a repayment price equal to 100% of the unpaid principal amount to be repaid, together with unpaid interest accrued thereon to the date fixed for repayment (the "Repayment Date"). For this Note to be repaid, the Trustee must receive at its office, currently located at 101 Barclay Street, 21 West, New York, New York, not more than 60 nor less than 30 calendar days prior to the Repayment Date, (i) in the case of a certificated note, such certificated note and the form thereon entitled "Option to Elect Repayment" duly completed or (ii) in the case of a book-entry note, instructions to such effect from the applicable Beneficial Owner to the Depositary and forwarded by the Depositary. Exercise of such repayment option by the Holder hereof will be irrevocable. In the event of repayment of this Note in part only, a new Note of like tenor and terms for the unrepaid portion hereof and otherwise having the same terms as this Note shall be issued by the Company in the name of the Holder hereof without charge, upon the presentation and 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 Notes shall relate, in the case of any Notes redeemed or to be redeemed by the Company only in part, to that portion of the principal amount of such Notes that has been or is to be so redeemed.

If an Event of Default with respect to the 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 also contains provisions permitting the Holders of a majority in aggregate principal amount of the Outstanding Securities of each series, 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 or, 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.

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

Interest on this Note will accrue from, and including, the immediately preceding Interest Payment Date to which interest has been paid or duly provided for (or from, and including, the Original Issue Date if no interest has been paid or duly provided for) to, but excluding, the applicable Interest Payment Date or the Stated Maturity, as the case may be (each, an "Interest Period"). The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, subject to certain exceptions described herein, 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 fifteenth calendar day (whether or not a Business Day, as defined below) immediately preceding such Interest Payment Date (the "Record Date"); provided, however, that interest payable on the Maturity will be payable to the Person to whom the principal hereof and premium, if any, hereon shall be payable. 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, except that if LIBOR is an applicable Interest Rate Basis and such Business Day falls in the next succeeding calendar month, such Interest Payment Date shall be the immediately preceding 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 ("Defaulted Interest") on any Interest Payment Date other than the at Maturity will forthwith cease to be payable

to the Holder hereof as of the close of business on the related Record Date and, instead, 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 (the "Special Record Date") for the payment of such Defaulted Interest to be fixed by the Company, written notice whereof shall be given to the Holder of this Note by the Company not less than 10 calendar 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 in the Borough of Manhattan, The City of New York, or at any other place designated by the Company for such purpose, and, if the Specified Currency is U.S. dollars, 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, if the Holder hereof is the Holder of U.S. $1,000,000 (or the equivalent thereof in a currency other than U.S. dollars determined as provided on the reverse hereof) or more in aggregate principal amount of Notes having the same Interest Payment Dates, at the option of the Company, such U.S. dollar interest payments will be made 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. Any wire instructions received by the Trustee shall remain in effect until revoked by the Holder. Simultaneously with any election by the Holder hereof to receive payments in respect hereof in the Specified Currency (if other than U.S. dollars), such Holder shall provide appropriate wire transfer instructions to the Trustee and all such payments will be made by wire transfer of immediately available funds to an account maintained by the payee with a bank located outside the United States.

acknowledge or effectuate the subordination as provided in the Indenture and appoints the Trustee as such Holder's attorney-in-fact for any and all such purposes.]

The principal hereof and any premium and interest hereon are payable by the Company in the Specified Currency shown above. If the Specified Currency shown above is other than U.S. dollars, the Company will arrange to convert all payments in respect hereof into U.S. dollars in the manner described below. The Holder hereof may, if so indicated above, elect to receive all payments in respect hereof in the Specified Currency by notifying the participant of the depositary through which its interest is held, or, in the case of certificated notes, the Trustee, at its office in the Borough of Manhattan, the City of New York, or at such other place as the Company may designate, on or before the applicable Record Date, in the case of a payment of interest, and on or before the sixteenth day, whether or not a Business Day, before its Stated Maturity, in the case of principal or premium, of the Holder's election to receive all or a portion of any payment in a Specified Currency. In the case of book-entry notes, the participant must notify the depositary of any election on or before the third Business Day after the Record Date. The depositary or the Trustee, as applicable, will notify the Paying Agent of the election on or before the fifth Business Day after the Record Date. If complete instructions are received by the participant and forwarded to the depositary, and forwarded by the depositary to the Paying Agent, on or before the relevant dates, the beneficial owner of this Note will receive payments in the Specified Currency. Such election will remain in effect until revoked by written notice to the Trustee received not later than fifteen calendar days prior to the applicable payment date. If the Company determines that the Specified Currency is not available for making payments in respect hereof due to the imposition of exchange controls or other circumstances beyond the Company's control or is no longer used by the government of the country issuing such currency or for the settlement of transactions by public institutions or within the international banking community, then the Holder hereof may not so elect to receive payments in the Specified Currency, and any such outstanding election shall be automatically suspended, and payments shall be in U.S. dollars, until the Company determines that the Specified Currency is again available for making such payments.

Notwithstanding the foregoing, if an Addendum is attached hereto this Note as specified above, this Note shall be subject to the terms set forth in such Addendum.

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.

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 U.S. dollar equivalent of the public offering price or purchase price of Notes denominated in currencies other than U.S. dollars will be determined by The Bank of New York, as exchange rate agent for the Notes (the "Exchange Rate Agent") pursuant to the Exchange Rate Agency Agreement, dated as of March 6, 2002, between the Company and the Exchange Rate Agent.

Except as set forth above or specified on the face hereof or in an Addendum hereto, the interest rate in effect on each day shall be (i) if such day is an Interest Reset Date, the interest rate determined as of the Interest Determination Date (as defined below) immediately preceding such Interest Reset Date or (ii) if such day is not an Interest Reset Date, the interest rate determined as of the Interest Determination Date immediately preceding the most recent Interest Reset Date. If any Interest Reset Date would otherwise be a day that is not a Business Day, such Interest Reset Date shall be postponed to the next succeeding Business Day, except that if LIBOR is an applicable Interest Rate Basis and such Business Day falls in the next succeeding calendar month, such Interest Reset Date shall be the immediately preceding Business Day. In addition, if the Treasury Rate is an applicable Interest Rate Basis and the Interest Determination Date would otherwise fall on an Interest Reset Date, then such Interest Reset Date will be postponed to the next succeeding Business Day.

The interest rate applicable to each Interest Reset Period commencing on the related Interest Reset Date will be the rate determined by the Calculation Agent as of the applicable Interest Determination Date and will be calculated by the Calculation Agent on or prior to the Calculation Date (as defined below), except with respect to LIBOR and the Eleventh District Cost of Funds Rate, which will be calculated on such Interest Determination Date. The "Interest Determination Date" with respect to the CD Rate, the CMT Rate, the Commercial Paper Rate, the Federal Funds Rate and the Prime Rate will be the second Business Day immediately preceding the applicable Interest Reset Date; the "Interest Determination Date" with respect to the Eleventh District Cost of Funds Rate shall be the last Business Day of the month immediately preceding the applicable Interest Reset Date on which the Federal Home Loan Bank of San Francisco (the "FHLB of San Francisco") publishes the Index (as defined below); and the "Interest Determination Date" with respect to LIBOR shall be the second London Business Day immediately preceding the applicable Interest Reset Date, unless the Designated LIBOR Currency is British pounds sterling, in which case the "Interest Determination Date" will be the applicable Interest Reset Date. The "Interest Determination Date" with respect to the Treasury Rate shall be the day in the week in which the applicable Interest Reset Date falls on which day Treasury Bills (as defined below) are normally auctioned (Treasury Bills are normally sold at an auction held on Monday of each week, unless such Monday is a legal holiday, in which case the auction is normally held on the immediately succeeding Tuesday, although such auction may be held on the preceding Friday); provided, however, that if an auction is held on the Friday of the week preceding the applicable Interest Reset Date, the "Interest Determination Date" shall be such preceding Friday; provided, further, that if the Interest Determination Date would otherwise fall on an Interest Reset Date then such Interest Reset Date will be postponed to the next succeeding Business Day. If the interest rate of this Note is determined with reference to two or more Interest Rate Bases specified on the face hereof, the "Interest Determination Date" pertaining to this Note shall be the most recent Business Day which is at least two Business Days prior to the applicable Interest Reset Date on which each Interest Rate Basis is determinable. Each Interest Rate Basis shall be determined as of such date, and the applicable interest rate shall take effect on the related Interest Reset Date.

Unless otherwise specified on the face hereof or in an Addendum hereto, the rate with respect to each Interest Rate Basis will be determined by the Calculation Agent in accordance with the applicable provisions below.

CD Rate. If an Interest Rate Basis for this Note is specified on the face hereof as the CD Rate, the CD Rate shall be determined as of the applicable Interest Determination Date (a "CD Rate Interest Determination Date") as the rate on such date for negotiable United States dollar certificates of deposit having the Index Maturity specified on the face hereof as published in H.15(519) (as defined below) under the heading "CDs (secondary market)" or, if not published by 3:00 P.M., New York City time, on the related Calculation Date, the rate on such CD Rate Interest Determination Date for negotiable United States dollar certificates of deposit of the Index Maturity specified on the face hereof as published in H.15 Daily Update (as hereinafter defined), or such other recognized electronic source used for the purpose of displaying such rate, under the heading "CDs (secondary market).". If such rate is not yet published in H.15(519), H.15 Daily Update or another recognized electronic source by 3:00 P.M., New York City time, on the related Calculation Date, then the CD Rate on such CD Rate Interest Determination Date will be calculated by the Calculation Agent specified on the face hereof and will be the arithmetic mean of the secondary market offered rates as of 10:00 A.M., New York City time, on such CD Rate Interest Determination Date, of three leading nonbank dealers in negotiable United States dollar certificates of deposit in The City of New York (which may include the agents or their respective affiliates (the "Agents," which term, as used herein, includes their respective successors) or their affiliates) selected by the Calculation Agent for negotiable United States dollar certificates of deposit of major United States money market banks for negotiable United States dollar certificates of deposit with a remaining maturity closest to the Index Maturity specified on the face hereof in an amount that is representative for a single transaction in that market at that time; provided, however, that if the dealers so selected by the Calculation Agent are not quoting as mentioned in this sentence, the CD Rate determined as of such CD Rate Interest Determination Date will be the CD Rate in effect on such CD Rate Interest Determination Date.

"H.15(519)" means the weekly statistical release designated as such, or any successor publication, published by the Board of Governors of the Federal Reserve System.

"H.15 Daily Update" means the daily update of H.15(519), available through the world-wide-web site of the Board of Governors of the Federal Reserve System at http://www.federalreserve.gov/releases/h15/update, or any successor site or publication.

CMT Rate. If an Interest Rate Basis for this Note is specified on the face hereof as the CMT Rate, the CMT Rate shall be determined as of the applicable Interest Determination Date (a"CMT Rate Interest Determination Date") as the rate displayed on the Designated CMT Moneyline Telerate Page (as defined below) under the caption "...Treasury Constant Maturities...Federal Reserve Board Release H.15...Mondays Approximately 3:45 P.M.", under the column for the Designated CMT Maturity Index (as defined below) for (i) if the Designated CMT Moneyline Telerate Page is 7051, the rate on such CMT Rate Interest Determination Date and (ii) if the Designated CMT Moneyline Telerate Page is 7052, the weekly or monthly average, as specified on the face hereof, for the week or the month, as applicable, ended immediately preceding the week or the month, as applicable, in which the related CMT Rate Interest Determination Date falls. If such rate is no longer displayed on the relevant page or is not so displayed by 3:00 P.M., New York City time, on the related Calculation Date, then the CMT Rate for such CMT Rate Interest Determination Date will be such treasury constant maturity rate for the Designated CMT Maturity Index as published in H.15(519). If such rate is no longer published or is not so published by 3:00 P.M., New York City time, on the related Calculation Date, then the CMT Rate on such CMT Rate Interest Determination Date will be such treasury constant maturity rate for the Designated CMT Maturity Index (or other United States Treasury rate for the Designated CMT Maturity Index) for the CMT Rate Interest Determination Date with respect to such Interest Reset Date as may then be published by either the Board of Governors of the Federal

Reserve System or the United States Department of the Treasury that the Calculation Agent determines to be comparable to the rate formerly displayed on the Designated CMT Moneyline Telerate Page and published in H.15(519). If such information is not so provided by 3:00 P.M., New York City time, on the related Calculation Date, then the CMT Rate on the CMT Rate Interest Determination Date will be calculated by the Calculation Agent and will be a yield to maturity, based on the arithmetic mean of the secondary market offered rates as of approximately 3:30 P.M., New York City time, on such CMT Rate Interest Determination Date reported, according to their written records, by three leading primary United States government securities dealers in The City of New York (which may include the Agents or their affiliates) (each, a "Reference Dealer") selected by the Calculation Agent (from five such Reference Dealers selected by the Calculation Agent and eliminating the highest quotation (or, in the event of equality, one of the highest) and the lowest quotation (or, in the event of equality, one of the lowest)), for the most recently issued direct noncallable fixed rate obligations of the United States ("Treasury Notes") with an original maturity of approximately the Designated CMT Maturity Index and a remaining term to maturity of not less than such Designated CMT Maturity Index minus one year. If the Calculation Agent is unable to obtain three such Treasury Note quotations, the CMT Rate on such CMT Rate Interest Determination Date will be calculated by the Calculation Agent and will be a yield to maturity based on the arithmetic mean of the secondary market offered rates as of approximately 3:30 P.M., New York City time, on such CMT Rate Interest Determination Date of three Reference Dealers in The City of New York (from five such Reference Dealers selected by the Calculation Agent and eliminating the highest quotation (or, in the event of equality, one of the highest) and the lowest quotation (or, in the event of equality, one of the lowest)), for Treasury Notes with an original maturity of the number of years that is the next highest to the Designated CMT Maturity Index and a remaining term to maturity closest to the Designated CMT Maturity Index and in an amount of at least U.S. $100 million. If three or four (and not five) of such Reference Dealers are quoting as described above, then the CMT Rate will be based on the arithmetic mean of the offered rates obtained and neither the highest nor the lowest of such quotes will be eliminated; provided, however, that if fewer than three Reference Dealers selected by the Calculation Agent are quoting as mentioned herein, the CMT Rate determined as of such CMT Rate Interest Determination Date will be the CMT Rate in effect on such CMT Rate Interest Determination Date. If two Treasury Notes with an original maturity as described in the second preceding sentence have remaining terms to maturity equally close to the Designated CMT Maturity Index, the Calculation Agent will obtain quotations for the Treasury Note with the shorter remaining term to maturity.

"Designated CMT Moneyline Telerate Page" means the display on Moneyline Telerate (or any successor service) on the page specified on the face hereof (or any other page as may replace such page on such service) for the purpose of displaying Treasury Constant Maturities as reported in H.15(519) or, if no such page is specified on the face hereof, page 7052.

"Designated CMT Maturity Index" means the original period to maturity of the U. S. Treasury securities (either 1, 2, 3, 5, 7, 10, 20 or 30 years) specified on the face hereof with respect to which the CMT Rate will be calculated or if no such maturity is specified on the face hereof, 2 years.

Commercial Paper Rate. If an Interest Rate Basis for this Note is specified on the face hereof as the Commercial Paper Rate, the Commercial Paper Rate shall be determined as of the applicable Interest Determination Date (a "Commercial Paper Rate Interest Determination Date") as the Money Market Yield (as defined below) on such date of the rate for commercial paper having the Index Maturity specified on the face hereof as published in H.15(519) under the heading "Commercial Paper-Nonfinancial" or, if not so published by 3:00 P.M., New York City time, on the related Calculation Date, the Money Market Yield of the rate on such Commercial Paper Rate Interest Determination Date for commercial paper having the Index Maturity as published in H.15 Daily Update, or such other recognized electronic source used for the purpose of displaying such rate, under the caption "Commercial Paper-Nonfinancial." If such rate is not yet published in H.15(5I9), H.15 Daily Update or

another recognized electronic source by 3:00 P.M., New York City time, on the related Calculation Date, then the Commercial Paper Rate on such Commercial Paper Rate Interest Determination Date will be calculated by the Calculation Agent and shall be the Money Market Yield of the arithmetic mean of the offered rates at approximately 11:00 A.M., New York City time, on such Commercial Paper Rate Interest Determination Date of three leading dealers of United States dollar commercial paper in The City of New York (which may include the Agents or their affiliates) selected by the Calculation Agent for commercial paper having the Index Maturity specified on the face hereof placed for industrial issuers whose bond rating is "Aa", or the equivalent, from a nationally recognized statistical rating organization; provided, however, that if the dealers so selected by the Calculation Agent are not quoting as mentioned in this sentence, the Commercial Paper Rate determined as of such Commercial Paper Rate Interest Determination Date will be the Commercial Paper Rate in effect on such Commercial Paper Rate Interest Determination Date.

"Money Market Yield" means a yield (expressed as a percentage) calculated in accordance with the following formula:

where "D" refers to the applicable per annum rate for commercial paper quoted on a bank discount basis and expressed as a decimal, and "M" refers to the actual number of days in the applicable Interest Reset Period.

Eleventh District Cost of Funds Rate. If an Interest Rate Basis for this Note is specified on the face hereof as the Eleventh District Cost of Funds Rate, the Eleventh District Cost of Funds Rate shall be determined as of the applicable Interest Determination Date (an "Eleventh District Cost of Funds Rate Interest Determination Date"), as the rate equal to the monthly weighted average cost of funds for the calendar month immediately preceding the month in which such Eleventh District Cost of Funds Rate Interest Determination Date falls, as set forth under the caption "11th District" on the display on Moneyline Telerate (or any successor service) on page 7058 (or any other page as may replace such page on such service) ("Moneyline Telerate Page 7058") as of 11:00 A.M., San Francisco time, on such Eleventh District Cost of Funds Rate Interest Determination Date. If such rate does not appear on Moneyline Telerate Page 7058 on such Eleventh District Cost of Funds Rate Interest Determination Date, then the Eleventh District Cost of Funds Rate on such Eleventh District Cost of Funds Rate Interest Determination Date shall be the monthly weighted average cost of funds paid by member institutions of the Eleventh Federal Home Loan Bank District that was most recently announced (the "Index") by the FHLB of San Francisco as such cost of funds for the calendar month immediately preceding such Eleventh District Cost of Funds Rate Interest Determination Date. If the FHLB of San Francisco fails to announce the Index on or prior to such Eleventh District Cost of Funds Rate Interest Determination Date for the calendar month immediately preceding such Eleventh District Cost of Funds Rate Interest Determination Date, the Eleventh District Cost of Funds Rate determined as of such Eleventh District Cost of Funds Rate Interest Determination Date will be the Eleventh District Cost of Funds Rate in effect on such Eleventh District Cost of Funds Rate Interest Determination Date.

Federal Funds Rate. If an Interest Rate Basis for this Note is specified on the face hereof as the Federal Funds Rate, the Federal Funds Rate shall be determined as of the applicable Interest Determination Date (a "Federal Funds Rate Interest Determination Date") as the rate on such date for United States dollar federal funds as published in H.15(519) under the heading "Federal Funds (Effective)", as such rate is displayed on Moneyline Telerate (or any successor service) on page 120 (or any other page as may replace such page on such service) ("Moneyline Telerate Page 120"), or, if such rate does not appear on Moneyline Telerate Page 120 or is not so published by 3:00 P.M., New York

City time, on the related Calculation Date, the rate on such Federal Funds Rate Interest Determination Date for United States dollar federal funds as published in H.15 Daily Update, or such other recognized electronic source used for the purpose of displaying such rate, under the heading "Federal Funds (Effective)." If such rate does not appear on Moneyline Telerate Page 120 or is not yet published in H.15(519), H.15 Daily Update or another recognized electronic source by 3:00 P.M., New York City time, on the related Calculation Date, then the Federal Funds Rate on such Federal Funds Rate Interest Determination Date shall be calculated by the Calculation Agent and will be the arithmetic mean of the rates for the last transaction in overnight United States dollar federal funds arranged by three leading brokers of United States dollar federal funds transactions in The City of New York (which may include the Agents or their affiliates) selected by the Calculation Agent, prior to 9:00 A.M., New York City time, on such Federal Funds Rate Interest Determination Date; provided, however, that if the brokers so selected by the Calculation Agent are not quoting as mentioned in this sentence, the Federal Funds Rate determined as of such Federal Funds Rate Interest Determination Date will be the Federal Funds Rate in effect on such Federal Funds Rate Interest Determination Date.

Prime Rate. If an Interest Rate Basis for this Note is specified on the face hereto as the Prime Rate, the Prime Rate shall be determined as of the applicable Interest Determination Date (a "Prime Rate Interest Determination Date") as the rate on such date as such rate is published in H.15(519) under the caption "Bank Prime Loan", or if not published by 3:00 P.M., New York City time, on the related Calculation Date, the rate on such Prime Rate Interest Determination Date as published in H.15 Daily Update, or such other recognized electronic source used for the purpose of displaying such rate, under the caption "Bank Prime Loan." If such rate is not yet published in H.15(519), H.15 Daily Update or another recognized electronic source by 3:00 P.M., New York City time, on the related Calculation Date, the Prime Rate shall be the arithmetic mean of the rates of interest publicly announced by at least four banks that appear on the Reuters Screen US PRIME 1 Page (as defined below) as such bank's prime rate or base lending rate as of 11:00 A.M., New York City time, on such Prime Rate Interest Determination. If fewer than four such rates so appear on the Reuters Screen US PRIME 1 Page for such Prime Rate Interest Determination Date, the Prime Rate shall be the arithmetic mean of the prime rates or base lending rates quoted on the basis of the actual number of days in the year divided by a 360-day year as of the close of business on such Prime Rate Interest Determination Date by three major banks (which may include affiliates of the Agents) in The City of New York; provided, however, that if the banks so selected by the Calculation Agent are not quoting as mentioned in this sentence, the Prime Rate determined as of such Prime Rate Interest Determination Date will be the Prime Rate in effect on such Prime Rate Interest Determination Date.

If an Interest Rate Basis for this Note is specified on the face hereof as the Treasury Rate, the Treasury Rate shall be determined as of the applicable Interest Determination Date (a "Treasury Rate Interest Determination Date"), as the rate from the auction held on such Treasury Rate Interest Determination Date (the "Auction") of direct obligations of the United States ("Treasury Bills") having the Index Maturity specified above under the caption "INVESTMENT RATE" on the display on Bridge Telerate, Inc. (or any successor service) on page 56 (or any other page as may replace such page on such service) ("Telerate Page 56") or page 57 (or any other page as may replace such page on such service) ("Telerate Page 57") or, if not so published by 3:00 P.M., New York City time, on the related Calculation Date, the Bond Equivalent Yield (as hereinafter defined) of the rate for such Treasury Bills as published in H.15 Daily Update, or such other recognized electronic source used for the purpose of displaying such rate, under the caption "U.S. Government Securities/Treasury Bills/Auction High" or, if not so published by 3:00 P.M., New York City time, on the related Calculation Date, the Bond Equivalent Yield of the auction rate of such Treasury Bills as announced by the United States Department of the Treasury. In the event that the auction rate of Treasury Bills having the Index Maturity specified above is not so announced by the United States Department of the Treasury, or if no such auction is held, then the Treasury Rate will be the Bond Equivalent Yield of the rate on such Treasury Rate Interest Determination Date of Treasury Bills having the Index Maturity specified above as published in H.15(519) under the caption "U.S. Government Securities/Treasury Bills/Secondary Market" or, if not yet published by 3:00 P.M., New York City time, on the related Calculation Date, the rate on such Treasury Rate Interest Determination Date of such Treasury Bills as published in H.15 Daily Update, or such other recognized electronic source used for the purpose of displaying such rate, under the caption "U.S. Government Securities/Treasury Bills/Secondary Market." If such rate is not yet published in H.15(519), H.15 Daily Update or another recognized electronic source, then the Treasury Rate will be calculated by the Calculation Agent and will be the Bond Equivalent Yield of the arithmetic mean of the secondary market bid rates, as of approximately 3:30 P.M., New York City time, on such Treasury Rate Interest Determination Date, of three primary United States government securities dealers (which may include the Agents or their affiliates) selected

by the Calculation Agent, for the issue of Treasury Bills with a remaining maturity closest to the Index Maturity specified on the face hereof; provided, however, that if the dealers so selected by the Calculation Agent are not quoting as mentioned in this sentence, the Treasury Rate determined as of such Treasury Rate Interest Determination Date will be the Treasury Rate in effect on such Treasury Rate Interest Determination Date.

"Bond Equivalent Yield" means a yield (expressed as a percentage) calculated in accordance with the following formula:

where "D" refers to the applicable per annum rate for Treasury Bills quoted on a bank discount basis, "N" refers 365 or 366, as the case may be, and "M" refers to the actual number of days in the applicable Interest Reset Period.

Index Notes. If an Interest Rate Basis for this Note is specified on the face hereof as Other, or an Index Rate, that Interest Rate Basis shall be determined in accordance with an addendum hereto.

Notwithstanding the foregoing, the interest rate hereon shall not be greater than the Maximum Interest Rate, if any, or less than the Minimum Interest Rate, if any, in each case as specified on the face hereof. The interest rate on this Note 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.

The "Calculation Date", if applicable, pertaining to any Interest Determination Date shall be the earlier of (i) the tenth calendar day after such Interest Determination Date or, if such day is not a Business Day, the next succeeding Business Day or (ii) the Business Day immediately preceding the applicable Interest Payment Date or the Maturity, as the case may be. At the request of the Holder hereof or, if this Note is in book-entry form, the beneficial owner hereof, the Trustee will provide to such Holder or beneficial owner, as the case may be, the interest rate hereon then in effect and, if determined, the interest rate that will become effective as a result of a determination made for the next succeeding Interest Reset Date.

Accrued interest hereon shall be an amount calculated by multiplying the principal amount hereof by an accrued interest factor. Such accrued interest factor shall be computed by adding the interest factor calculated for each day in the applicable Interest Period. Unless otherwise specified as the Day Count Convention on the face hereof, the interest factor for each such day shall be computed by dividing the interest rate applicable to such day by 360 if the CD Rate, the Commercial Paper Rate, the Eleventh District Cost of Funds Rate, the Federal Funds Rate, LIBOR or the Prime Rate is an applicable Interest Rate Basis or by the actual number of days in the year if the CMT Rate or the Treasury Rate is an applicable Interest Rate Basis. Unless otherwise specified as the Day Count Convention on the face hereof, the interest factor for this Note, if the interest rate hereon is calculated with reference to two or more Interest Rate Bases, shall be calculated in each period in the same manner as if only the applicable Interest Rate Basis specified on the face hereof applied.

All percentages resulting from any calculation on this Note (other than percentages used in the calculation of the accrued interest factor and accrued interest) shall be rounded to the nearest one hundred-thousandth of a percentage point, with five one-millionths of a percentage point rounded upwards, and all amounts used in or resulting from such calculation on this Note shall be rounded, in the case of United States dollars, to the nearest cent or, in the case of a Specified Currency other than United States dollars, to the nearest unit. For purposes of rounding, .005 shall be rounded upwards.

If so specified on the face hereof or in an addendum hereto, the Interest Rate, Spread, Spread Multiplier or method of calculation, as the case may be, on this Note may be reset by the Company on the date or dates specified on the face hereof or in an addendum hereto or delivered herewith (each an "Optional Reset Date"). Not later than 40 days prior to each Optional Reset Date, the Trustee will mail to the Holder of this Note a notice (the "Reset Notice"), first class, postage prepaid, indicating whether the Company has elected to reset the Interest Rate, Spread, Spread Multiplier or method of calculation, as the case may be, and if so, (i) such new Interest Rate, Spread, Spread Multiplier or method of calculation, and (ii) the provisions, if any, for redemption during the period from such Optional Reset Date to the next Optional Reset Date, or, if there is no such next Optional Reset Date, to the Stated Maturity of this Note (each such period, a "Subsequent Interest Period"), including the date or dates on which or the period or periods during which and the price or prices at which such redemption may occur during the Subsequent Interest Period. Upon the transmittal by the Trustee of a Reset Notice to the holder of a Note, such new Interest Rate, Spread, Spread Multiplier or method of calculation, as the case may be, shall take effect automatically. Except as modified by the Reset Notice and as described below, such Note will have the same terms as prior to the transmittal of such Reset Notice. Notwithstanding the foregoing, not later than 20 days prior to an Optional Reset Date, the Company may, at its option, revoke the Interest Rate, Spread or Spread Multiplier provided for in the Reset Notice and establish a higher Interest Rate, Spread or Spread Multiplier for the Subsequent Interest Period by causing the Trustee to mail notice of such higher Interest Rate, Spread or Spread Multiplier to the Holder of this Note. Such notice shall be irrevocable. All Notes with respect to which the Interest Rate, Spread or Spread Multiplier is reset on an Optional Reset Date will bear such higher Interest Rate, Spread or Spread Multiplier whether or not tendered for repayment.

If this Note is an Indexed Principal Note, then the principal amount payable at Stated Maturity or earlier redemption or retirement is determined by reference to the amount designated on the face hereof or in an addendum hereto as the face amount of this Note and by reference to the Index as described on the face hereof or in an addendum hereto. If this Note is an Indexed Principal Note, the principal amount payable at Stated Maturity or any earlier redemption or repayment of this Note may be different from the face amount.

supplement. Any determination by the selected third party will be binding on all parties, except in the case of an obvious error.

"Tranche"), of thereafter making all payments of principal, premium, if any, and interest (which payments would otherwise be made in the Specified Currency of such Notes) in an optional currency (the "Optional Payment Currency"). Such option will be exercisable in whole but not in part on an Option Election Date, which will be any one of the dates specified on the face hereof or in an addendum hereto.

If the Company makes such an election, the amount payable in the Optional Payment Currency shall be determined using the Designated Exchange Rate specified on the face hereof or in an addendum hereto or delivered herewith. If such election is made, notice of such election shall be mailed in accordance with the terms of the applicable Tranche of Dual Currency Notes within two Business Days of the Option Election Date and shall state (i) the first date, whether an Interest Payment Date and/or Stated Maturity, on which scheduled payments in the Optional Payment Currency will be made and (ii) the Designated Exchange Rate. Any such notice by the Company, once given, may not be withdrawn. The equivalent value in the Specified Currency of payments made after such an election may be less, at the then current exchange rate, than if the Company had made such payment in the Specified Currency.

Note, in a principal amount equal to the principal amount of such exchanged Note for which no election to renew the term thereof was exercised, with terms identical to those specified on such exchanged Note (except that such Note shall have a fixed, nonrenewable Stated Maturity on the New Maturity Date) and (ii) if an election to renew is made with respect to less than the full principal amount of such Holder's Note, the Trustee, or any duly appointed paying agent, shall issue in exchange for such Note in the name of such Holder, a replacement Renewable Note, in a principal amount equal to the principal amount of such exchanged Note for which the election to renew was made, with terms otherwise identical to the exchanged Note.

"Redemption Date"), on written notice given to the Holder hereof (in accordance with the provisions of the Indenture) not more than 60 nor less than 30 calendar days prior to the Redemption Date. The "Redemption Price" shall be the Initial Redemption Percentage specified on the face hereof (as adjusted by the Annual Redemption Percentage Reduction, if any, specified on the face hereof as set forth below) multiplied by the unpaid principal amount of this Note to be redeemed. The Initial Redemption Percentage, if any, shall decline at each anniversary of the Initial Redemption Date by the Annual Redemption Percentage Reduction, if any, until the Redemption Price is equal to 100% of the unpaid principal amount to be redeemed. Whenever less than all of the Notes of like tenor and terms are to be redeemed, the Notes to be redeemed and the Holders thereof shall be selected by the Trustee by such method as the Trustee shall deem fair and reasonable. In the event of redemption of this Note in part only, a new Note of like tenor and otherwise having the same terms as this Note for the unredeemed portion hereof shall be issued by the Company in the name of the Holder hereof, without charge, upon the presentation and surrender hereof.

If this Note is specified on the face hereof to be a Discount Note, the amount payable to the Holder of this Note in the event of redemption, repayment or acceleration of maturity of this Note will be equal to the sum of (1) the Issue Price specified on the face hereof plus any accruals of the Discount, as defined below, and, in the event of any redemption of this Note (if applicable), multiplied by the Initial Redemption Percentage (as adjusted by the Annual Redemption Percentage Reduction, if applicable) and (2) any unpaid interest accrued thereon to the Redemption Date, Repayment Date or date of acceleration of maturity, as the case may be. The difference between the Issue Price and 100% of the principal amount of this Note is referred to herein as the "Discount."

For purposes of determining the amount of Discount that has accrued as of any Redemption Date, Repayment Date or date of acceleration of maturity of this Note, such Discount will be accrued so as to cause the yield on this Note to be constant. The constant yield will be calculated using a 30-day month, 360-day year convention, a compounding period that, except for the Initial Period (as defined below), corresponds to the shortest period between Interest Payment Dates (with ratable accruals within a compounding period) and an assumption that the maturity of this Note will not be accelerated. If the period from the Original Issue Date to the initial Interest Payment Date (the "Initial Period") is shorter than the compounding period for this Note, a proportionate amount of the yield for an entire compounding period will be accrued. If the Initial Period is longer than the compounding period, then such period will be divided into a regular compounding period and a short period, with the short

period being treated as provided in the preceding sentence. The Company shall be responsible for determining, directly or through an agent, the amount of any accrued Discount on this Note.

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

If an Event of Default with respect to the 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 Notes. 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 not less than a majority in principal amount of the Outstanding Securities of each series to be affected. The Indenture also contains provisions permitting the Holders of a majority in aggregate principal amount of the Outstanding Securities of each series, 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.

denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

The Indenture and the Notes 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. If "OTHER" is specified under "INTEREST RATE BASIS OR BASES" above, references herein to "this Note," "hereof," "herein," and comparable terms shall include the addendum hereto that specifies the applicable Interest Rate Basis or Bases.

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 face amount hereof, or, in the case of an Indexed Principal Note, the face amount hereof, adjusted by reference to prices, changes in prices, or differences between prices, of securities, currencies, intangibles, goods, articles or commodities or by such other objective price, economic or other measures (an "Index") as described on the face hereof or in the pricing supplement attached hereto or delivered herewith (the "principal" or "principal amount"), in the Specified Currency specified above on the Stated Maturity specified above (unless and to the extent earlier redeemed or repaid prior to such Stated Maturity) and to pay interest on the principal amount then outstanding at the Interest Rate shown above from the Original Issue Date specified above or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually in arrears on and , in each year, commencing with the first Interest Payment Date next succeeding the Original Issue Date, at the rate per annum set forth above, until the principal amount hereof is paid or made available for payment; provided, however, that if the Original Issue Date of this Note is between a Regular Record Date (as defined below) and the related Interest Payment Date, the first payment of interest on this Note will be made on the Interest Payment Date immediately following the next succeeding Regular Record Date to the registered Holder on such next succeeding Regular Record Date. 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 fifteenth calendar day (whether or not a Business Day), (the "Regular Record Date") as the case may be, next preceding such Interest Payment Date; provided, however, that interest payable at the Stated Maturity or earlier redemption or repayment of this Note (the "Maturity") shall be payable to the Person to whom principal shall be payable. 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 other than at Maturity (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 (l) 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), written notice of which shall be given to the Holder of this Note by the Company not less than 10 calendar 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. In the case of a default in payment of principal upon acceleration or at the Maturity Date, the Accreted Value (as defined below) of this Note at the date of such default in payment shall bear interest at the Yield to Maturity specified above plus 1% per annum (to the extent that the payment of such interest shall be legally enforceable), which shall accrue from the date of such default in payment to the date payment of such principal has been made or duly provided for. Such interest will be computed on the basis of a 360-day year of twelve 30-day months, compounded semi-annually. Payment of the principal of and interest, if any, 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 any other place designated by the Company for such purpose, and, if the Specified Currency is U.S. dollars, 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, if the Holder hereof is the Holder of U.S. $1,000,000 (or the equivalent thereof in a currency other than U.S. dollars determined as provided on the reverse hereof) or more in aggregate principal amount of Notes having the same Interest Payment Dates, at the option of the Company, such U.S. dollar interest payments will be made 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. Any wire instructions received by the Trustee shall remain in effect until revoked by the Holder. Simultaneously with any election by the Holder hereof to receive payments in respect hereof in the Specified Currency (if other than U.S. dollars), such Holder shall provide appropriate wire transfer instructions to the Trustee and all such payments will be made by wire transfer of immediately available funds to an account maintained by the payee with a bank located outside the United States.

The "Accreted Value" of this Note at any date (the "Calculation Date") shall be equal to (i) the Original Issue Price of this Note specified above plus (ii) the accrued amortization of Original issue Discount specified above attributable ratably on a daily basis to the period from and including the Original Issue Date specified above to but excluding such Calculation Date. The calculation of accrual of Original Issue Discount will be computed on the basis of a 360-day year of twelve 30-day months, compounded semi-annually.

The principal hereof and any premium and interest hereon are payable by the Company in the Specified Currency shown above. If the Specified Currency shown above is other than U.S. dollars, the

Company will arrange to convert all payments in respect hereof into U.S. dollars in the manner described below. The Holder hereof may, if so indicated above, elect to receive all payments in respect hereof in the Specified Currency by notifying the participant of the depositary through which its interest is held, or, in the case of certificated notes, the Trustee, at its office in the Borough of Manhattan, the City of New York, or at such other place as the Company may designate, on or before the applicable Regular Record Date, in the case of a payment of interest, and on or before the sixteenth day, whether or not a Business Day, before its Stated Maturity, in the case of principal or premium, of the Holder's election to receive all or a portion of any payment in a Specified Currency. In the case of book-entry notes, the participant must notify the depositary of any election on or before the third Business Day after the Regular Record Date. The depositary or the Trustee, as applicable, will notify the Paying Agent of the election on or before the fifth Business Day after the Regular Record Date. If complete instructions are received by the participant and forwarded to the depositary, and forwarded by the depositary to the Paying Agent, on or before the relevant dates, the beneficial owner of this Note will receive payments in the Specified Currency. Such election will remain in effect until revoked by written notice to the Trustee received not later than fifteen calendar days prior to the applicable payment date. If the Company determines that the Specified Currency is not available for making payments in respect hereof due to the imposition of exchange controls or other circumstances beyond the Company's control or is no longer used by the government of the country issuing such currency or for the settlement of transactions by public institutions or within the international banking community, then the Holder hereof may not so elect to receive payments in the Specified Currency, and any such outstanding election shall be automatically suspended, and payments shall be in U.S. dollars, until the Company determines that the Specified Currency is again available for making such payments.

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.

Notwithstanding the foregoing, if an Addendum is attached hereto as specified above, this Note shall be subject to the terms set forth in such Addendum.

Exchange Rate Agency Agreement, dated as of March 6, 2002, between the Company and the Exchange Rate Agent.

This Note will bear interest at the rate per annum stated on the face hereof or in an addendum attached hereto until the principal amount hereof is paid or made available for payment, except as otherwise described below under "Subsequent Interest Periods" and "Extension of Maturity," and except that if so specified in an addendum hereto, the rate of interest payable on certain Fixed Rate Notes may be subject to adjustment as specified therein.

hereof or in an addendum hereto as the face amount of this Note and by reference to the Index as described on the face hereof or in an addendum hereto.

This Note will be subject to redemption at the option of the Company on any date on or after the first Optional Redemption Date, if any, specified on the face hereof, in whole or from time to time in part in increments of U.S.$1,000 (if the Specified Currency is U.S. dollars) or such other increment specified on the face hereof under Authorized Denomination (if the Specified Currency is not U.S. dollars) (provided that any remaining principal amount hereof shall be an Authorized Denomination and at least the minimum Authorized Denomination hereof) at the Redemption Price (as defined below), together with unpaid interest accrued thereon to the date fixed for redemption (the "Redemption Date"), on written notice given to the Holder hereof (in accordance with the provisions of the Indenture) not more than 60 nor less than 30 calendar days prior to the Redemption Date. The "Redemption Price" shall be the Initial Redemption Percentage specified on the face hereof (as adjusted by the Annual Redemption Percentage Reduction, if any, specified on the face hereof as set forth below) multiplied by the Accreted Value of this Note to be redeemed. The Initial Redemption Percentage, if any, shall decline at each anniversary of the Initial Redemption Date by the Annual Redemption Percentage Reduction, if any, until the Redemption Price is equal to 100% of the Accreted Value of this Note to be redeemed. Whenever less than all of the Notes of like tenor and terms are to be redeemed, the Notes to be redeemed and the Holders thereof shall be selected by the Trustee by such method as the Trustee shall deem fair and reasonable. In the event of redemption of this Note in part only, a new Note of like tenor and otherwise having the same terms as this Note for the unredeemed portion hereof shall be issued by the Company in the name of the Holder hereof, without charge, upon the presentation and surrender hereof.

This Note will be subject to repayment by the Company at the option of the Holder hereof on the Optional Repayment Date(s), if any, specified on the face hereof, in whole or from time to time in part in increments of U.S.$l,000 (if the Specified Currency is U.S. dollars) or such other increment specified on the face hereof under Authorized Denomination (if the Specified Currency is not U.S. dollars) (provided that any remaining principal amount hereof shall be an Authorized Denomination and at least the minimum Authorized Denomination hereof) at a repayment price equal to 100% of the Accreted Value of this Note, together with unpaid interest accrued thereon to the date fixed for repayment (the "Repayment Date"). For this Note to be repaid, the Trustee must receive at its office, currently located at 101 Barclay Street, 21 West, New York, New York, not more than 60 nor less than 30 calendar days prior to the Repayment Date, (i) in the case of a certificated note, such certificated note and the form thereon entitled "Option to Elect Repayment" duly completed or (ii) in the case of a book-entry note, instructions to such effect from the applicable Beneficial Owner to the Depositary and forwarded by the Depositary.

In the event of repayment of this Note in part only, a new Note of like tenor and terms for the unrepaid portion hereof and otherwise having the same terms as this Note shall be issued by the Company in the name of the Holder hereof without charge, upon the presentation and surrender hereof.

If an Event of Default with respect to the Notes shall occur and be continuing, a portion of the principal of this Note may be declared due and payable in the manner and with the effect provided in the Indenture. Such portion shall be equal to the Accreted Value of this Note at the time of payment with respect to such declaration. Upon payment (i) of such Accreted Value and (ii) of interest on any overdue Accreted Value (to the extent that the payment of such interest shall be legally enforceable), all of the Company's obligations in respect of the payment of the principal of and interest on this Note shall terminate.
