We conduct our principal operations through two subsidiaries, Occidental Oil and Gas Corporation and Occidental Chemical Corporation, and our 29.5% interest in the Equistar Chemicals, LP petrochemicals partnership. Occidental was organized in April 1986 and, as the result of a reorganization effective May 21, 1986, became the successor to a California corporation of the same name organized in 1920. The words "Occidental," "Company," "we," "our" and "us" as used in this prospectus supplement refer only to Occidental Petroleum Corporation and not to any of our subsidiaries or any of the underwriters. USE OF PROCEEDS We intend to use the net proceeds from the sale of the notes (estimated to be approximately $594 million) for general corporate purposes, primarily the retirement of outstanding indebtedness. CAPITALIZATION The following table sets forth the consolidated short-term debt and consolidated capitalization of Occidental at September 30, 1998 (1) on a historical basis and (2) as adjusted to reflect the sale of the notes and the application of the estimated net proceeds from the sale of the notes to repay commercial paper (which we classify as long-term debt on our balance sheet). - -------- (1) Does not give effect to the anticipated use by Occidental of the proceeds from a note in the original principal amount of $1.4 billion, maturing on January 4, 1999, received in connection with Occidental's sale of MidCon Corp. to K N Energy, Inc. in exchange for a note previously issued to Occidental by the MidCon Corp.

The following description is a summary of the material provisions of the Indenture. It does not restate the Indenture in its entirety. We urge you to read the Indenture because it, and not this description, defines your rights as holders of the notes. We have filed a copy of the Indenture as an exhibit to the registration statement which includes the accompanying prospectus. This description of the notes supplements, and, to the extent it is inconsistent, replaces, the description of the general provisions of the notes and the Indenture in the accompanying prospectus. The notes are "Debt Securities" as that term is used in the accompanying prospectus and are also referred to in the prospectus as "Offered Securities." In this description, the term "Securities" refers to all Debt Securities that may be issued under the Indenture and includes the notes. BRIEF DESCRIPTION OF THE NOTES The notes are unsecured and rank equally with all of our other senior unsecured indebtedness. The Indenture does not limit the aggregate principal amount of Securities that we may issue under the Indenture and we may, without your consent, issue additional Securities thereunder. There are currently $1.17 billion aggregate principal amount of Securities outstanding under the Indenture. Substantially all of our operations are conducted through subsidiaries. As a result, our right to receive assets upon the liquidation or recapitalization of any of our subsidiaries (and your consequent right to participate in those assets) is subject to the claims of such subsidiary's creditors. Even if we are recognized as a creditor of one or more of our subsidiaries, our claims would still be subject to any security interests in the assets of any such subsidiary and to any indebtedness or other liabilities of any such subsidiary senior to our claims. Accordingly, both series of notes are effectively subordinated to all indebtedness and other liabilities, including trade payables, of our subsidiaries. As of September 30, 1998, the total amount of such indebtedness and other liabilities of our subsidiaries that would have been senior to both series of notes was approximately $2.3 billion (excluding interest). PRINCIPAL, MATURITY AND INTEREST The 2002 notes and the 2008 notes will be limited to $200 million and $400 million, respectively, aggregate principal amount and will mature on November 15, 2002 and November 15, 2008, respectively. Interest on the 2002 notes will accrue at the rate of 6.75% per year and interest on the 2008 notes will accrue at the rate of 7.375% per year, and, in each case, will be payable semiannually in arrears on May 15 and November 15, commencing on May 15, 1999. The Company will make each interest payment to the holders of record of the applicable series of notes on the immediately preceding May 1 and November 1. Interest on both series of notes will accrue from November 19, 1998 and will be computed on the basis of a 360-day year comprised of twelve 30-day months. If any interest payment date, maturity date or redemption date falls on a day that is not a business day, the payment will be made on the next business day and no interest will accrue for the period from and after such interest payment date, maturity date or redemption date. PLACE OF PAYMENT, TRANSFER AND EXCHANGE All payments on both series of notes will be made, and transfers of both series of notes will be registrable, at the Trustee's office in New York, unless we designate another place for such purpose. S-4 OPTIONAL REDEMPTION We may redeem some or all of either series of notes at any time at a price equal to the greater of: . 100% of the principal amount of the notes of such series to be redeemed; and . an amount determined by the Quotation Agent equal to the sum of the present values of the remaining scheduled payments of principal and interest on the notes of such series to be redeemed (not including any portion of such payments of interest accrued as of the redemption date) discounted to the redemption date on a semiannual basis (assuming a 360-day year comprised of twelve 30- day months) at the Adjusted Treasury Rate plus 25 basis points in the case of the 2002 notes and 35 basis points in the case of the 2008 notes; plus, in each case, accrued and unpaid interest to the redemption date; provided, however, that, with respect to interest payments that are due on or prior to the relevant redemption date, we will make such payments to the record holders of such notes at the close of business on the relevant regular record dates. We will send to each holder notice of any redemption at least 30 days but not more than 60 days before the applicable redemption date. Unless Occidental defaults in payment of the redemption price, no interest shall accrue for the period from and after such redemption date. If less than all of the notes of any series are to be redeemed, the Trustee will select the notes of such series (or portions thereof) to be redeemed by such method as the Trustee shall deem fair and appropriate. "Adjusted Treasury Rate" means, with respect to any redemption date, the rate per annum equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date. "Comparable Treasury Issue" means the United States Treasury security selected by the Quotation Agent as having a maturity comparable to the remaining term of the notes of the applicable series to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of such series of notes. "Comparable Treasury Price" means, with respect to any redemption date, (1) the average of the Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (2) if the Trustee obtains fewer than three such Reference Treasury Dealer Quotations, the average of such Quotations, such average in any case to be determined by the Quotation Agent, or (3) if only one Reference Treasury Dealer Quotation is received, such Quotation. "Quotation Agent" means the Reference Treasury Dealer appointed by Occidental. "Reference Treasury Dealer" means (1) Merrill Lynch, Pierce, Fenner & Smith Incorporated, Donaldson, Lufkin & Jenrette Securities Corporation, J.P. Morgan Securities Inc. and NationsBanc Montgomery Securities LLC (or their respective affiliates which are primary U.S. Government securities dealers) and their respective successors; provided, however, that if any of them shall cease to be a primary U.S. Government securities dealer in New York City (a "Primary Treasury Dealer"), Occidental shall substitute for it another Primary Treasury Dealer, and (2) any other Primary Treasury Dealer(s) selected by Occidental. "Reference Treasury Dealer Quotations" means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Quotation Agent, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m. on the third Business Day in the City of New York preceding such redemption date. FORM, DENOMINATION AND REGISTRATION Both series of notes will be issued only in fully registered form, without coupons, in minimum denominations of $1,000 and any integral multiple of $1,000 in excess thereof. Both series of notes will be deposited with, or on behalf of, DTC and will be represented by one or more Global Notes registered in the name of Cede & Co., as nominee of DTC. The interests of beneficial owners in the Global Notes will be represented through financial institutions acting on their behalf as direct or indirect participants in DTC. S-5 Ownership of beneficial interests in a Global Note will be limited to persons who have accounts with DTC ("participants") or persons who hold interests through participants. Ownership of beneficial interests in the Global Notes will be shown on, and the transfer of these ownership interests will be effected only through, records maintained by DTC or its nominee (with respect to interests of participants) and the records of participants (with respect to interests of persons other than participants). So long as DTC, or its nominee, is the registered owner or holder of a Global Note, DTC or such nominee, as the case may be, will be considered the sole owner or holder of the notes represented by such Global Note for all purposes under the Indenture and the notes. In addition, no beneficial owner of an interest in a Global Note will be able to transfer that interest except in accordance with DTC's applicable procedures (in addition to those under the Indenture). Payments on Global Notes will be made to DTC or its nominee, as the registered owner thereof. Neither the Company, the Trustee nor any paying agent will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in the Global Notes or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. The Company expects that DTC or its nominee will credit direct participants' accounts on the payable date with payments in respect of a Global Note in amounts proportionate to their respective beneficial interest in the principal amount of such Global Note as shown on the records of DTC or its nominee, unless DTC has reason to believe that it will not receive payment on the payable date. The Company also expects that payments by participants to owners of beneficial interests in such Global Note held through such participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers registered in "street name." Such payments will be the responsibility of such participants. Transfers between participants in DTC will be effected in accordance with DTC rules. The laws of some states require that certain persons take physical delivery of securities in definitive form. Consequently, the ability to transfer beneficial interests in a Global Note to such persons may be limited. Because DTC can only act on behalf of participants, who in turn act on behalf of indirect participants and certain banks, the ability of a person having a beneficial interest in a Global Note to pledge such interest to persons or entities that do not participate in the DTC system, or otherwise take actions in respect of such interest, may be affected by the lack of a physical certificate of such interest. The Company believes that it is the policy of DTC that it will take any action permitted to be taken by a holder of notes only at the direction of one or more participants to whose account interests in the Global Notes are credited and only in respect of such portion of the aggregate principal amount of the notes as to which such participant or participants has or have given such direction. If (1) the Depository notifies the Company that it is unwilling or unable to continue as Depository or if the Depository ceases to be eligible under the Indenture and a successor depository is not appointed by the Company within 90 days or (2) an event of default with respect to the notes of any series shall have occurred and be continuing, the Global Notes will be exchanged for notes in definitive form of like tenor and of an equal aggregate principal amount, in authorized denominations. Such definitive notes shall be registered in such name or names as the Depository shall instruct the Trustee. Such instructions will most likely be based upon directions received by the Depository from participants with respect to ownership of beneficial interests in Global Notes. DTC has advised the Company as follows: DTC is a limited-purpose trust company organized under the New York Banking Law, a "banking organization" within the meaning of the New York Banking Law, a member of the Federal Reserve System, a "clearing corporation" within the meaning of the New York Uniform Commercial Code and a "clearing agency" registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds securities that its participants deposit with DTC and facilitates the settlement among participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in participants' accounts, thereby eliminating the need for physical movement of securities certificates. Direct participants include securities brokers and dealers, banks, trust S-6 companies, clearing corporations and certain other organizations. DTC is owned by a number of its direct participants, including the underwriters, and by the New York Stock Exchange, Inc., the American Stock Exchange, Inc. and the National Association of Securities Dealers, Inc. Access to the DTC system is also available to others such as securities brokers and dealers, banks and trust companies that clear through or maintain a custodial relationship with a direct participant, either directly or indirectly ("indirect participants"). The rules applicable to DTC and its participants are on file with the SEC. DTC has further advised the Company that management of DTC is aware that some computer applications, systems, and the like for processing data that are dependent upon calendar dates, including dates before, on, and after January 1, 2000, may encounter "Year 2000 problems." DTC has informed its participants and other members of the financial community that it has developed and is implementing a program so that its systems, as the same relate to the timely payment of distributions (including principal and interest payments) to security holders, book-entry deliveries, and settlement of trades within DTC, continue to function appropriately. This program includes a technical assessment and a remediation plan, each of which is complete. Additionally, DTC's plan includes a testing phase, which is expected to be completed within appropriate time frames. However, DTC's ability to perform properly its services is also dependent upon other parties, including but not limited to issuers and their agents, as well as the DTC's direct and indirect participants and third party vendors from whom DTC licenses software and hardware, and third party vendors on whom DTC relies for information or the provision of services, including telecommunication and electrical utility service providers, among others. DTC has informed the industry that it is contacting (and will continue to contact) third party vendors from whom DTC acquires services to: (i) impress upon them the importance of such services being Year 2000 complaint; and (ii) determine the extent of their efforts for Year 2000 remediation (and, as appropriate, testing) of their services. In addition, DTC is in the process of developing such contingency plans as it deems appropriate. According to DTC, the foregoing information with respect to DTC has been provided to the industry for informational purposes only and is not intended to serve as a representation, warranty, or contract modification of any kind. Although DTC has agreed to the foregoing procedures in order to facilitate transfers of interests in the Global Notes among participants of DTC, it is under no obligation to perform or continue to perform such procedures, and such procedures may be discontinued at any time. Neither the Company nor the Trustee will have any responsibility for the performance by DTC or its participants or indirect participants of their respective obligations under the rules and procedures governing their operations. S-7 UNDERWRITING Subject to the terms and conditions set forth in an underwriting agreement (the "Underwriting Agreement"), the Company has agreed to sell to the underwriters named below (the "Underwriters"), and each of the Underwriters, for whom Merrill Lynch, Pierce, Fenner & Smith Incorporated, Donaldson, Lufkin & Jenrette Securities Corporation, J.P. Morgan Securities Inc. and NationsBanc Montgomery Securities LLC are acting as representatives (the "Representatives"), have severally agreed to purchase, the principal amount of notes set forth opposite their respective names below. In the Underwriting Agreement, the several Underwriters named therein have agreed, subject to the terms and conditions set forth therein, to purchase all of the notes being sold pursuant to the Underwriting Agreement if any such notes are purchased. The Underwriting Agreement provides that, in the event of a default by an Underwriter named in the Underwriting Agreement, the purchase commitments of the non-defaulting Underwriters named in the Underwriting Agreement may in certain circumstances be increased. The Representatives have advised the Company that they propose initially to offer the 2002 notes and the 2008 notes to the public at the respective public offering prices set forth on the cover page of this prospectus supplement and to certain dealers at such price less a concession not in excess of .35% of the principal amount in the case of the 2002 notes and not in excess of .4% of the principal amount in the case of the 2008 notes. The Underwriters may allow, and such dealers may reallow, a discount not in excess of .25% of the principal amount of either series of notes on sales to certain other dealers. After the initial public offering, the public offering price, concession and discount may be changed. We estimate that we will spend approximately $375,000 for fees and expenses associated with the offering of the 2002 notes and the 2008 notes. Both series of notes constitute a new issue of securities with no established trading market. The Company does not intend to apply for listing of either series of notes on a national securities exchange. We have been advised by the Underwriters that the Underwriters intend to make a market in both series of notes, but the Underwriters are not obligated to do so and may discontinue market-making at any time without notice. No assurance can be given as to whether or not a trading market for either series of notes will develop or as to the liquidity of any trading market for either series of notes which may develop. In connection with the offering, the Underwriters are permitted to engage in certain transactions that stabilize the price of the notes. Such transactions consist of bids or purchases for the purpose of pegging, fixing or maintaining the price of either or both series of notes. If the Underwriters create a short position in the notes of any series in connection with the offering, i.e., if they sell a greater aggregate principal amount of notes of such series than is set forth on the cover of this prospectus supplement, the Underwriters may reduce that short position by purchasing notes of such series in the open market. In general, purchases of a security for the purpose of stabilization or to reduce a short position could cause the price of the security to be higher than it might be in the absence of such purchases.

Securities may be issued as Discount Securities, which may be sold at a discount below their principal amount. Special United States Federal income tax considerations applicable to Securities issued at an original issue discount, including Discount Securities, may be described in any applicable Prospectus Supplement. Special United States Federal tax considerations and other restrictions or terms applicable to any Offered Securities that are (i) issuable in bearer form, (ii) offered exclusively to Non-United States Holders (as defined in the Indenture) or (iii) denominated in a currency other than United States dollars will be set forth in a Prospectus Supplement relating thereto. FORM, EXCHANGE, REGISTRATION AND TRANSFER The Securities of a series may be issued solely as Registered Securities, solely as Bearer Securities (with or without coupons attached) or as both Registered Securities and Bearer Securities. Securities of a series may be issuable in whole or part in the form of one or more global Securities, as described below under "Global Securities." Registered Securities of any series will be exchangeable for other Registered Securities of the same series of any authorized denominations and of a like aggregate principal amount and tenor. In addition, if Securities of any series are issuable as both Registered Securities and as Bearer Securities, at the option of the Holder, subject to the terms of the Indenture, Bearer Securities (accompanied by all unmatured coupons, except as provided below, and all matured coupons in default) of such series will be exchangeable for Registered Securities of the same series of any authorized denominations and of a like aggregate principal amount and tenor. Unless otherwise indicated in an applicable Prospectus Supplement, any Bearer Security surrendered in exchange for a Registered Security between a Regular Record Date or a Special Record Date and the relevant date for payment of interest will be surrendered without the coupon relating to such date for payment of interest and such interest will not be payable in respect of the Registered Security issued in exchange for such Bearer Security, but will be payable only to the Holder of such coupon when due in accordance with the terms of the Indenture. Bearer Securities will not be issued in exchange for Registered Securities. Securities may be presented for exchange as provided above, and, unless otherwise indicated in an applicable Prospectus Supplement, Registered Securities may be presented for registration of transfer (duly endorsed or accompanied by a duly executed written instrument of transfer), at the office of the Security Registrar 5 or at the office of any transfer agent designated by Occidental for such purpose with respect to any series of Securities and referred to in an applicable Prospectus Supplement, without service charge and upon payment of any taxes and other governmental charges as described in the Indenture. Such exchange or transfer, as the case may be, will be effected upon the Security Registrar or such transfer agent, as the case may be, being satisfied with the documents of title and identity of the person making the request. Occidental has initially appointed the Trustee as Security Registrar. If a Prospectus Supplement refers to any transfer agent (in addition to the Security Registrar) designated by Occidental with respect to any series of Securities, Occidental may at any time rescind the designation of any such transfer agent or approve a change in the location through which any such transfer agent acts, except that, if Securities of a series are issuable only as Registered Securities, Occidental will be required to maintain a transfer agent in each Place of Payment for such series, and, if Securities of a series are issuable as Bearer Securities, Occidental will be required to maintain a transfer agent in New York City and in a Place of Payment for such series located outside the United States. Occidental may at any time designate additional transfer agents with respect to any series of Securities. Occidental will not be required to (i) issue, register the transfer of or exchange Securities of any series during a period beginning at the opening of business 15 days before any selection of Securities of that series to be redeemed and ending (subject to certain exceptions) at the close of business on (a) if Securities of the series are issuable only as Registered Securities, the day of mailing of the relevant notice of redemption and (b) if Securities of the series are issuable as Bearer Securities, the day of the first publication of the relevant notice of redemption or, if Securities of the series are also issuable as Registered Securities and there is no publication, the mailing of the relevant notice of redemption; (ii) register the transfer of or exchange any Registered Security, or portion thereof, called for redemption, except the unredeemed portion of any Registered Security being redeemed in part; or (iii) exchange any Bearer Security called for redemption, except to exchange such Bearer Security for a Registered Security of that series and of like tenor and principal amount that is immediately surrendered for redemption. PAYMENT AND PAYING AGENTS Unless otherwise indicated in an applicable Prospectus Supplement, payment of principal of and interest, if any, on Registered Securities will be made at the office of such Paying Agent or Paying Agents as Occidental may designate from time to time, except that, at the option of Occidental, payment of any interest may be made (i) by check mailed to the address of the Person entitled thereto, as such address shall appear in the Security Register, or (ii) by wire transfer to an account maintained by the Person entitled thereto, as specified in the Security Register. Unless otherwise indicated in an applicable Prospectus Supplement, payment of any installment of interest on a Registered Security will be made to the Person in whose name such Registered Security is registered at the close of business on the Regular Record Date for such interest installment. Unless otherwise indicated in an applicable Prospectus Supplement, interest shall be computed on the basis of a 360-day year comprised of twelve 30-day months. Unless otherwise indicated in an applicable Prospectus Supplement, payment of principal of and interest, if any, on Bearer Securities will be made, subject to any applicable laws and regulations, at the offices of such Paying Agent or Paying Agents outside the United States as Occidental may designate from time to time, or by check mailed to an address or by transfer to an account maintained by the payee outside the United States. Unless otherwise indicated in an applicable Prospectus Supplement, any payment of an installment of interest on any Bearer Security will be made only against surrender of the coupon relating to such interest installment. Unless otherwise indicated in an applicable Prospectus Supplement, the Trustee, acting through its Corporate Trust Office, will be designated as Occidental's sole Paying Agent for payments with respect to Securities that are issuable solely as Registered Securities and as Occidental's Paying Agent in the Borough of Manhattan, The City of New York, for payments with respect to Securities (subject to any limitations described in any applicable Prospectus Supplement) that are issuable as Bearer Securities. Any Paying Agent outside the United States and any other Paying Agent in the United States initially designated by Occidental for the Offered 6 Securities will be named in an applicable Prospectus Supplement. Occidental may at any time designate one or more additional Paying Agents or rescind the designation of any Paying Agent or approve a change in the office through which any Paying Agent acts, except that, if Securities of a series are issuable only as Registered Securities, Occidental will be required to maintain a Paying Agent in each Place of Payment for such series, and, if Securities of a series are issuable as Bearer Securities, Occidental will be required to maintain (i) a Paying Agent in the Borough of Manhattan, The City of New York, for payments with respect to any Registered Securities of the series (and for payments with respect to Bearer Securities of the series in the circumstances described in the Indenture, but not otherwise) and (ii) a Paying Agent in a Place of Payment located outside the United States where Securities of such series and any related coupons may be presented and surrendered for payment; provided, however, that if the Securities of such series are listed on The London Stock Exchange or the Luxembourg Stock Exchange or any other stock exchange located outside the United States and such stock exchange shall so require, Occidental will maintain a Paying Agent in London, Luxembourg or any other required city located outside the United States, as the case may be, for the Securities of such series. All moneys paid by Occidental to a Paying Agent for the payment of principal of or interest, if any, on any Security that remain unclaimed at the end of two years after such principal or interest shall have become due and payable will be repaid to Occidental, and the Holder of such Security or any coupon will thereafter look only to Occidental for payment thereof. GLOBAL SECURITIES The Securities of a series may be issued in whole or in part in global form. A Security in global form will be deposited with, or on behalf of, a Depositary, which will be identified in an applicable Prospectus Supplement. A global Security may be issued in either registered or bearer form and in either temporary or definitive form. A Security in global form may not be transferred, except as a whole by the Depositary for such Security to a nominee of such Depositary, or by a nominee of such Depositary to such Depositary or another nominee of such Depositary, or by such Depositary or any such nominee to a successor of such Depositary or a nominee of such successor. If any Securities of a series are issuable in global form, the applicable Prospectus Supplement will describe the circumstances, if any, under which beneficial owners of interests in any such global Security may exchange such interests for definitive Securities of such series and of like tenor and principal amount in any authorized form and denomination, the manner of payment of principal of and interest, if any, on any such global Security and the specific terms of the depositary arrangement with respect to any such global Security. CERTAIN COVENANTS OF OCCIDENTAL Limitation on Liens. Occidental will not, nor will it permit any Consolidated Subsidiary (as defined below) to, incur, create, assume, guarantee or otherwise become liable with respect to any Secured Debt (as defined below), unless the Securities are secured equally and ratably with (or prior to) such Secured Debt. This covenant will not apply to: (i) Liens (as defined below) existing on the date of the Indenture; (ii) Liens existing on property of, or on any shares of stock or Indebtedness of, any corporation at the time such corporation becomes a Consolidated Subsidiary; (iii) Liens in favor of Occidental or a Consolidated Subsidiary; (iv) Liens in favor of governmental bodies to secure progress, advance or other payments; (v) Liens existing on property, shares of stock or Indebtedness at the time of acquisition thereof (including acquisition through merger or consolidation) or Liens to secure the payment of all or any part of the purchase price thereof or the cost of construction, installation, renovation, improvement or development thereon or thereof or to secure any Indebtedness incurred prior to, at the time of, or within 360 days after the later of the acquisition, completion of such construction, installation, renovation, improvement or development or the commencement of full operation of such property or within 360 days after the acquisition of such shares or Indebtedness for the purpose of financing all or any part of the purchase price or cost thereof; and (vi) any extension, renewal or refunding of any Liens referred to in the foregoing clauses (i) through (v). Notwithstanding the foregoing, Occidental and one or more Consolidated Subsidiaries may incur, create, assume, guarantee or otherwise become liable with respect to Secured Debt that would otherwise be subject to the foregoing restrictions if, after giving effect thereto, the aggregate amount of 7 all Secured Debt, together with all Discounted Rental Value (as defined below) in respect of sale and leaseback transactions subject to the restrictions discussed in the following paragraph (excluding sale and leaseback transactions exempted from such restrictions pursuant to clause (i) or (ii) of the last sentence of such paragraph), would not exceed 10% of consolidated Net Tangible Assets (as defined below) of Occidental and its consolidated subsidiaries. Limitation on Sale and Leaseback Transactions. Occidental will not nor will it permit any Consolidated Subsidiary to sell and lease back any Principal Domestic Property (as defined below) unless: (i) the transaction is one in which the sale has occurred within 360 days after the later of the acquisition, completion of construction or commencement of full operations of the Principal Domestic Property; (ii) Occidental or such Consolidated Subsidiary could subject such Principal Domestic Property to a Lien pursuant to the provisions described above under "Limitation on Liens" in an amount equal to the Discounted Rental Value with respect to the sale and leaseback transaction without equally and ratably securing the Securities; or (iii) Occidental or such Consolidated Subsidiary, within 120 days after such sale, applies or causes to be applied to the retirement of its Funded Debt (as defined below) an amount (subject to credits for certain voluntary retirements of Funded Debt) not less than the greater of (a) the net proceeds of the sale of the Principal Domestic Property leased pursuant to such arrangement or (b) the fair value (as determined in any manner approved by the Board of Directors of Occidental) of the Principal Domestic Property so leased. This restriction will not apply to any sale and leaseback transaction (i) between Occidental and a Consolidated Subsidiary or between Consolidated Subsidiaries or (ii) involving the taking back of a lease for a period, including renewals, of not more than three years. Other than the limitations in the Indenture on Liens and sale and leaseback transactions described above, the provisions of the Indenture do not afford Holders of the Debt Securities protection in the event of a highly leveraged transaction, reorganization, restructuring, change in control, merger or similar transaction involving Occidental that may adversely affect Holders of the Debt Securities. CERTAIN DEFINITIONS "Consolidated Subsidiary" means any Subsidiary included in the financial statements of Occidental and its Subsidiaries prepared on a consolidated basis in accordance with generally accepted accounting principles. "Discounted Rental Value" means, as to any particular lease under which any Person is at the time liable and at any date as of which the amount thereof is to be determined, the total net amount of rent (after deducting the amount of rent to be received by such Person under noncancelable subleases) required to be paid by such Person under such lease during the remaining noncancelable term thereof (including any such period for which such lease has been extended or may, at the option of the lessor, be extended), discounted from the respective due dates thereof to such date at a rate per annum of 11 3/4%. The net amount of rent required to be paid under any such lease for any such period shall be the aggregate amount of the rent payable by the lessee with respect to such period, after excluding amounts required to be paid on account of maintenance and repairs, insurance, taxes, water rates and similar charges. In the case of any lease which is terminable by the lessee upon the payment of a penalty, such net amount shall also include the amount of such penalty, but no rent shall be considered as required to be paid under such lease subsequent to the first date upon which it may be so terminated. If and to the extent the amount of any rent during any future period is not definitely determinable under the lease in question, the amount of such rent shall be estimated in such reasonable manner as the Board of Directors of Occidental may in good faith determine. "Funded Debt" means all Indebtedness maturing one year or more from the date of the creation thereof, all Indebtedness directly or indirectly renewable or extendible, at the option of the debtor, by its terms or by the terms of any instrument or agreement relating thereto, to a date one year or more from the date of the creation thereof, and all Indebtedness under a revolving credit or similar agreement obligating the lender or lenders to extend credit over a period of one year or more, even though such Indebtedness may also conform to the definition of Short-Term Borrowing. 8 "Lien" means and includes any mortgage, pledge, lien, security interest, conditional sale or other title retention agreement or other similar encumbrance to secure Indebtedness for borrowed money but excluding any security interest which a lessor may be deemed to have under a lease and any lien which may be deemed to exist under a Production Payment or under any subordination arrangement. "Production Payment" means any economic interest in oil, gas or mineral reserves which (i) entitles the holder thereof to a specified share of future production from such reserves, free of the costs and expenses of such production and (ii) terminates when a specified quantity of such share of future production from such reserves has been delivered or a specified sum has been realized from the sale of such share of future production from such reserves. "Net Tangible Assets" of any specified Person means the total of all assets properly appearing on a balance sheet of such Person prepared in accordance with generally accepted accounting principles, after deducting from such total, without duplication of deductions, (i) all Current Liabilities of such Person; (ii) that portion of the book amount of all such assets which would be treated as intangibles under generally accepted accounting principles, including, without limitation, all such items as goodwill, trademarks, trade names, brands, copyrights, patents, licenses and rights with respect to the foregoing and unamortized debt discount and expense; and (iii) the amount, if any, at which any stock of such Person appears on the asset side of such balance sheet. "Principal Domestic Property" means any (i) developed oil or gas producing property or (ii) processing or manufacturing plant, in each case which as of the date of the Indenture is or thereafter is owned or leased by Occidental or any Consolidated Subsidiary and which is located in the continental United States (provided, however, that any such property or plant declared by the Board of Directors by Board Resolution not to be of material importance to the business of Occidental and its Consolidated Subsidiaries taken as a whole will be excluded from the foregoing definition). "Secured Debt" means any Indebtedness of Occidental or any Consolidated Subsidiary, secured by a Lien on any Principal Domestic Property or on any shares of stock or on any Indebtedness of any Consolidated Subsidiary which owns any Principal Domestic Property. MERGER AND CONSOLIDATION Occidental may consolidate with or merge into any other corporation, and Occidental may convey, transfer or lease its properties and assets substantially as an entirety to any Person, provided that: (i) the corporation formed by such consolidation or into which Occidental is merged, or the Person that acquires by conveyance or transfer or which leases the properties and assets of Occidental substantially as an entirety, shall be organized and existing under the laws of the United States, any State thereof or the District of Columbia and shall expressly assume the payment of the principal of and interest on the Securities and the performance of every covenant of the Indenture and the Securities on the part of Occidental to be performed or observed; and (ii) immediately after giving effect to such transaction, no Event of Default (as described below), and no event which, after notice or lapse of time, or both, would become an Event of Default, shall have happened and be continuing. EVENTS OF DEFAULT The following are Events of Default under the Indenture with respect to each series of Securities individually: (i) default in the payment of any installment of interest on any Security of such series when due, continued for 30 days; or (ii) default in the payment of the principal of any Security of such series when due; or (iii) default in the performance, or breach, of any other covenant or warranty of Occidental in the Indenture (other than a covenant or warranty that is solely for the benefit of other series of the Securities), continued for 60 days after written notice by the Trustee or the Holders of at least 25% in principal amount of the Outstanding Securities of such series; or (iv) acceleration of any indebtedness for money borrowed by Occidental under the terms of the instrument under which such indebtedness is or may be outstanding, if such indebtedness is not discharged or such acceleration is not annulled or rescinded within 20 days after written notice by the Trustee or the Holders of at least 25% in principal amount of the Outstanding Securities of such series (provided, that no Event of Default under this clause (iv) shall be deemed to exist as a result of an acceleration of any such 9 indebtedness if the principal of and interest on such indebtedness, when added to the principal of and interest on all other such indebtedness which has been accelerated as aforesaid (excluding any such indebtedness which has been discharged or as to which the acceleration has been duly rescinded or annulled), shall not exceed $50,000,000); or (v) certain events of bankruptcy, insolvency or reorganization of Occidental; or (vi) any other event designated in the relevant Prospectus Supplement as an "Event of Default" with respect to the Securities of such series. If an Event of Default with respect to the Securities of any series occurs and is continuing, the Trustee or Holders of not less than 25% in principal amount of the Outstanding Securities of such series may declare the principal amount (or, if any of the Securities of such series are Discount Securities, such portion of the principal amount of such Securities as may be specified by the terms thereof) of all of the Securities of such series to be due and payable immediately. Under certain circumstances, the Holders of a majority in principal amount of the Outstanding Securities of such series may rescind such a declaration. The Holders of a majority in principal amount of the Outstanding Securities of any series may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee with respect to the Securities of such series, provided that, among other things, such direction is not in conflict with any rule of law or the Indenture. In case an Event of Default occurs (and is not cured), the Trustee is required to exercise such of its rights and powers under the Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of his own affairs. Subject to such provisions, the Trustee is under no obligation to exercise any of its rights or powers under the Indenture at the request or direction of any of the Holders of the Securities of any series, unless such Holders have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities that might be incurred by it in compliance with any such request or direction. MODIFICATION AND WAIVER Occidental and the Trustee may execute a supplemental indenture, without the consent of the Holders of the Securities or any related coupons: (i) to add to the covenants, agreements and obligations of Occidental for the benefit of the Holders of all the Securities of any series or to surrender any right or power conferred in the Indenture upon Occidental; (ii) to evidence the succession of another person to Occidental and the assumption by it of the covenants of Occidental in the Indenture and the Securities; (iii) to provide that Bearer Securities may be registrable as to principal, to change or eliminate any restrictions on the payment of principal of or interest, if any, on Bearer Securities, to permit Bearer Securities to be issued in exchange for Registered Securities, to permit Bearer Securities to be issued in exchange for Bearer Securities of other authorized denominations or to permit the issuance of Securities in uncertificated form, provided that any such action shall not adversely affect the interests of the Holders of Securities of any series or any related coupons in any material respect; (iv) to establish the form or terms of Securities of any series and any related coupons as permitted by Sections 201 and 301 of the Indenture; (v) to provide for the acceptance of appointment under the Indenture of a successor Trustee with respect to the Securities of one or more series and to add to or change any provisions of the Indenture as shall be necessary to provide for or facilitate the administration of the trusts by more than one Trustee; (vi) to cure any ambiguity or correct any inconsistency in the Indenture or make other changes, provided that no such action shall adversely affect the interests of the Holders of the Securities; (vii) to add to, change or eliminate any provisions (which addition, change or elimination may apply to one or more series of Securities), provided that any such addition, change or elimination neither (a) applies to any Security of any series created prior to the execution of such supplemental indenture that is entitled to the benefit of such provision nor (b) modifies the rights of the Holder of any such Security with respect to such provision; or (viii) to secure the Securities. With the consent of the Holders of not less than a majority in principal amount of the Outstanding Securities of the series affected by such supplemental indenture, Occidental and the Trustee also may execute a supplemental indenture to add provisions to, or change in any manner or eliminate any provisions of, the Indenture with respect to such series of Securities or modify in any manner the rights of the holders of the Securities of such series and any related coupons under the Indenture, provided that no such supplemental indenture will, without the consent of the Holder of each Outstanding Security affected thereby: (i) change the 10 stated maturity of the principal of, or any installment of principal or interest on, any such Security, or reduce the amount of principal of any such Discount Security that would be due and payable upon declaration of acceleration of maturity thereof; (ii) reduce the principal amount of, or the rate of interest on, or any premium payable on, any such Security; (iii) change the place or currency of payment of principal or interest, if any, on any such Security; (iv) impair the right to institute suit for the enforcement of any payment on or with respect to any such Security; (v) reduce the above- stated percentage of Holders of Securities of any series necessary to modify or amend the Indenture; or (vi) modify the foregoing requirements or reduce the percentage in principal amount of Outstanding Securities of any series necessary to waive any covenant or past default. Holders of not less than a majority in principal amount of the Outstanding Securities of any series may waive certain past defaults and may waive compliance by Occidental with certain of the restrictive covenants in the Indenture (including the restrictive covenants described above under "Certain Covenants of Occidental") with respect to the Securities of such series. DISCHARGE Unless otherwise indicated in an applicable Prospectus Supplement, Occidental may terminate at any time its obligations under the Indenture with respect to the Securities of any series by (i)(a) delivering all Outstanding Securities of such series to the Trustee for cancellation or (b) depositing with the Trustee funds or non-callable United States government obligations sufficient to pay all remaining principal and interest on the Securities of such series and (ii) complying with certain other provisions of the Indenture. If Occidental exercises its right to satisfy and discharge its obligations under the Indenture with respect to any series of the Debt Securities prior to its maturity by depositing funds or non-callable United States government obligations in trust for holders of outstanding Debt Securities of that series, such satisfaction and discharge ("discharge"), under present law, is likely to be treated as a redemption of the Debt Securities of that series prior to maturity in exchange for the property deposited in trust. In such event, each holder would generally recognize, at the time of discharge, gain or loss measured by the difference between (i) the sum of (a) the amount of any cash and (b) the fair market value of any property deposited in trust deemed received by the holder (except to the extent attributable to accrued interest) and (ii) the holder's tax basis in the Debt Securities deemed surrendered. Thereafter, each holder would be treated as if it held an undivided interest in the cash (or investments made therewith) and the property held in trust. Each holder would generally be subject to tax liability in respect of interest income and original issue discount, if applicable, thereon and would recognize any gain or loss upon any disposition, including redemption, of the assets held in trust. Although tax might be owed, the holder of a discharged Debt Security would not receive cash (except for current payments of interest on such Debt Security) until the maturity or earlier redemption of such Debt Security. Such tax treatment could affect the purchase price that a holder would receive upon the sale of the Debt Securities. REPORTS Occidental is required to furnish to the Trustee annually (i) a statement as to the fulfillment by Occidental of all of its covenants under the Indenture and (ii) within 20 days after the occurrence thereof, notice of each acceleration which, with the giving of notice and the lapse of time, would be an Event of Default, as described above in clause (iv) under "Events of Default." THE TRUSTEE The Trustee is a New York banking corporation. The Trustee is a participating lender under a revolving credit agreement of Occidental and provides commercial banking services to Occidental and certain of its subsidiaries. The Indenture contains certain limitations on the rights of the Trustee, as a creditor of Occidental, to obtain payment of claims in certain cases or to realize on certain property received in respect of any such claim as security or otherwise. The Trustee will be permitted to engage in other transactions with Occidental and its subsidiaries; provided, however, that if the Trustee acquires any conflicting interest at such time as a default is pending under the Indenture, it must (with certain exceptions) eliminate such conflict or resign. 11 PLAN OF DISTRIBUTION Occidental may sell Debt Securities to one or more underwriters for public offering and sale by them or may sell Debt Securities to investors directly or through agents or dealers. Any such underwriter, agent or dealer involved in the offer and sale of the Debt Securities will be named in the applicable Prospectus Supplement. Occidental may also sell Offered Securities to an agent as principal. Underwriters may offer and sell the Offered Securities at a fixed price or prices, which may be changed, or from time to time at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at negotiated prices. Occidental also may, from time to time, authorize underwriters acting as its agents to offer and sell the Offered Securities upon the terms and conditions set forth in any Prospectus Supplement. In connection with the sale of Offered Securities, underwriters may be deemed to have received compensation from Occidental in the form of underwriting discounts or commissions and may also receive commissions from purchasers of Offered Securities for whom they may act as agent. Underwriters may sell Offered Securities to or through dealers, and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions (which may be changed from time to time) from the purchasers for whom they may act as agent. If a dealer is utilized in the sale of the Offered Securities in respect of which this Prospectus is delivered, Occidental will sell such Offered Securities to such dealer, as principal. The dealer may then resell such Offered Securities to the public at varying prices to be determined by such dealer at the time of resale. Any underwriting compensation paid by Occidental to underwriters or agents in connection with the offering of Offered Securities, and any discounts, concessions or commissions allowed by underwriters to participating dealers, will be set forth in an applicable Prospectus Supplement. Underwriters, dealers and agents participating in the distribution of the Offered Securities may be deemed to be underwriters under the Securities Act, and any discounts and commissions received by them and any profit realized by them on resale of the Offered Securities may be deemed to be underwriting discounts and commissions under the Securities Act. Underwriters, dealers and agents may be entitled under agreements with Occidental to indemnification against and contribution toward certain civil liabilities, including liabilities under the Securities Act, and to reimbursement by Occidental for certain expenses. If so indicated in an applicable Prospectus Supplement, Occidental will authorize dealers acting as its agents to solicit offers by certain institutions to purchase Offered Securities from Occidental at the public offering price set forth in such Prospectus Supplement pursuant to Delayed Delivery Contracts ("Contracts") providing for payment and delivery on the date or dates stated in such Prospectus Supplement. Each Contract will be for an amount not less than, and the aggregate principal amount or offering price of Offered Securities sold pursuant to Contracts shall not be less nor more than, the respective amounts stated in such Prospectus Supplement. Institutions with whom Contracts, when authorized, may be made include commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions and other institutions, but will in all cases be subject to the approval of Occidental. Offered Securities may also be offered and sold, if so indicated in the Prospectus Supplement, in connection with a remarketing upon their purchase, in accordance with a redemption or repayment pursuant to their terms, or otherwise, by one or more firms ("remarketing firms"), acting as principals for their own accounts or as agents for Occidental. Any remarketing firm will be identified and the terms of its agreement, if any, with Occidental and its compensation will be described in the Prospectus Supplement. Remarketing firms may be deemed to be underwriters in connection with the Offered Securities remarketed thereby. Remarketing firms may be entitled under agreements which may be entered into with Occidental to indemnification by Occidental against certain liabilities, including liabilities under the Securities Act. The Debt Securities may or may not be listed on a national securities exchange or a foreign securities exchange. No assurances can be given that there will be a market for any of the Debt Securities. 12 LEGAL MATTERS Certain legal matters with respect to the legality of the Debt Securities being offered hereby will be passed upon for Occidental by Robert E. Sawyer, Esq., Associate General Counsel of Occidental, and by Skadden, Arps, Slate, Meagher & Flom LLP, Los Angeles, California. Mr. Sawyer beneficially owns, and has rights to acquire under employee stock options, an aggregate of less than 1% of the outstanding common stock of Occidental. 13 - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- $600,000,000 OCCIDENTAL PETROLEUM CORPORATION $200,000,000 6.75% SENIOR NOTES DUE 2002 $400,000,000 7.375% SENIOR NOTES DUE 2008 --------------------------------- PROSPECTUS SUPPLEMENT --------------------------------- MERRILL LYNCH & CO.
