You should carefully consider the<br \/>\nfollowing risk factors, in addition to the other information contained or<br \/>\nincorporated by reference in this prospectus supplement and the accompanying<br \/>\nprospectus. Specifically, please see &#8220;Risk Factors&#8221; included in our Annual<br \/>\nReport on Form 10-K for the year ended December 31, 2010 and the other<br \/>\ninformation in that and the other reports that we file with the Securities and<br \/>\nExchange Commission, or SEC, that are incorporated by reference in this<br \/>\nprospectus supplement for a discussion of risk factors that may affect our<br \/>\nbusiness. Realization of any of those risks or the following risks or adverse<br \/>\nresults from any matter listed under the heading &#8220;Forward-Looking Statements&#8221; in<br \/>\nthe accompanying prospectus or in any such reports could have a material adverse<br \/>\neffect on our business, financial condition, cash flows and results of<br \/>\noperations, and you might lose all or part of your investment.<\/em><\/p>\n<p><strong>Risks Related to the Notes <\/strong><\/p>\n<p><strong><em>The notes will be effectively subordinated to the indebtedness<br \/>\nand other liabilities of our subsidiaries. <\/em><\/strong><\/p>\n<p>Substantially all of our operations are conducted through our subsidiaries.<br \/>\nNone of our subsidiaries is a guarantor of the notes. As a result, our right to<br \/>\nreceive assets upon the liquidation or recapitalization of any of our<br \/>\nsubsidiaries, and your consequent right to benefit from our receipt of those<br \/>\nassets, will be subject to the claims of such subsidiary&#8217;s creditors.<br \/>\nAccordingly, the notes are effectively subordinated to all indebtedness and<br \/>\nother liabilities, including trade payables, of our subsidiaries. Even if we<br \/>\nwere recognized as a creditor of one or more of our subsidiaries, our claims<br \/>\nwould still be effectively subordinated to any security interests in or other<br \/>\nliens on the assets of any such subsidiary and to any indebtedness or other<br \/>\nliabilities of any such subsidiary senior to our claims.<\/p>\n<p>In addition, we derive substantially all of our revenues from our<br \/>\nsubsidiaries. As a result, our cash flow and our ability to service our debt and<br \/>\nother obligations, including the notes, will depend on the results of operations<br \/>\nof our subsidiaries and upon the ability of our subsidiaries to provide us with<br \/>\ncash to pay amounts due on our obligations, including the notes. Our<br \/>\nsubsidiaries are separate and distinct legal entities and have no obligation to<br \/>\nmake payments on the notes or to make funds available to us for that purpose. In<br \/>\naddition, dividends, loans or other distributions from our subsidiaries to us<br \/>\nmay be subject to contractual and other restrictions, are dependent upon results<br \/>\nof operations of our subsidiaries, may be subject to tax or other laws limiting<br \/>\nour ability to repatriate funds from foreign subsidiaries and may be subject to<br \/>\nother business considerations.<\/p>\n<p><strong><em>The notes will be unsecured and therefore will be effectively<br \/>\nsubordinated to any secured indebtedness we may incur. <\/em><\/strong><\/p>\n<p>The notes will not be secured by any of our assets. As a result, the notes<br \/>\nwill be effectively subordinated to any secured debt we or our subsidiaries may<br \/>\nincur in the future to the extent of the value of the assets securing such debt.<br \/>\nIn any liquidation, dissolution, bankruptcy or other similar proceeding, the<br \/>\nholders of any of our secured debt and the secured debt of our subsidiaries may<br \/>\nassert rights against the assets pledged to secure that debt in order to receive<br \/>\nfull payment of their debt before the assets may be used to pay other creditors,<br \/>\nincluding the holders of the notes.<\/p>\n<p><strong><em>Our credit ratings may not reflect all risks of an investment in<br \/>\nthe notes and there is no protection in the indenture for holders of the notes<br \/>\nin the event of a ratings downgrade. <\/em><\/strong><\/p>\n<p>Our credit ratings are an assessment by rating agencies of our ability to pay<br \/>\nour debts when due but they may not reflect the potential impact of all risks<br \/>\nrelated to an investment in the notes. Consequently, real or anticipated changes<br \/>\nin our credit ratings will generally affect the market value of the notes.<br \/>\nCredit ratings are not a recommendation to buy, sell or hold any security, and<br \/>\nmay be revised or withdrawn at any time by the issuing organization in its sole<br \/>\ndiscretion. We have no<\/p>\n<p align=\"center\">S-1<\/p>\n<hr>\n<p>obligation to maintain the ratings and neither we nor any underwriter<br \/>\nundertakes any obligation to advise holders of notes of any change in ratings.<br \/>\nEach agency&#8217;s rating should be evaluated independently of any other agency&#8217;s<br \/>\nrating.<\/p>\n<p><strong><em>The indenture does not limit the amount of indebtedness that we<br \/>\nor our subsidiaries may incur. <\/em><\/strong><\/p>\n<p>The indenture does not limit our ability or that of our subsidiaries to incur<br \/>\nadditional indebtedness or contain provisions that would afford holders of the<br \/>\nnotes protection in the event of a decline in our credit quality or a take-over,<br \/>\nrecapitalization or highly leveraged or similar transaction. Accordingly, we and<br \/>\nour subsidiaries could, in the future, enter into transactions that could<br \/>\nincrease the amount of indebtedness outstanding at that time or otherwise<br \/>\nadversely affect your position in our consolidated capital structure or our<br \/>\ncredit ratings.<\/p>\n<p><strong><em>If an active trading market does not develop for the notes, you<br \/>\nmay be unable to sell your notes or to sell your notes at a price that you deem<br \/>\nsufficient. <\/em><\/strong><\/p>\n<p>The notes are a new issue of securities with no established trading market,<br \/>\nand we do not intend to list them on any securities exchange or automated<br \/>\nquotation system. As a result, an active trading market for the notes may not<br \/>\ndevelop, or if one does develop, it may not be sustained. If an active trading<br \/>\nmarket fails to develop or cannot be sustained, you may not be able to resell<br \/>\nyour notes at their fair market value or at all.<\/p>\n<p align=\"center\">S-2<\/p>\n<hr>\n<p align=\"center\">  <strong>OCCIDENTAL <\/strong><\/p>\n<p>Our principal businesses consist of three segments operated by our<br \/>\nsubsidiaries and affiliates.

The notes are<br \/>\n&#8220;senior debt securities&#8221; as that term is used in the accompanying prospectus,<br \/>\nthe indenture is referred to in the accompanying prospectus as the &#8220;Senior<br \/>\nIndenture&#8221; and the trustee is referred to in the accompanying prospectus as the<br \/>\n&#8220;Senior Indenture Trustee.&#8221; In this description, the term &#8220;Securities&#8221; refers to<br \/>\nall senior debt securities that may be issued under the indenture and includes<br \/>\nthe notes.<\/p>\n<p><strong>Description of the Notes <\/strong><\/p>\n<p>The notes are unsecured and will rank equally in right of payment with all of<br \/>\nour other senior unsecured indebtedness. The indenture does not limit the<br \/>\naggregate principal amount of Securities that we may issue under the indenture<br \/>\nand we may, without the consent of holders of outstanding Securities, issue<br \/>\nadditional Securities thereunder. In addition, the indenture does not limit the<br \/>\namount of other unsecured debt that we or our subsidiaries may issue or incur.<br \/>\nSuch other unsecured debt may have different terms than the notes. Our<br \/>\npreviously issued and outstanding senior debt does have different terms than the<br \/>\nnotes (including different restrictive covenants and event of default<br \/>\nprovisions). The terms of the notes will only be as described in the indenture,<br \/>\nthe accompanying prospectus and this prospectus supplement.

After the discharge, each such holder<br \/>\nwould likely be treated as if it held an undivided interest in the cash (or<br \/>\ninvestments made therewith) and the property held in trust (or investments made<br \/>\nwith interest received therefrom). Each such holder would generally be subject<br \/>\nto tax liability in respect of interest income and original issue discount, if<br \/>\napplicable, thereon and would recognize any gain or loss upon any disposition,<br \/>\nincluding redemption, of the assets held in trust. Although tax might be owed,<br \/>\nthe holder of a discharged note would not receive cash (except for current<br \/>\npayments of interest on that note) until the maturity or earlier redemption (or,<br \/>\nif applicable, repurchase by us at the option of the holder) of that note.<br \/>\nUnited States federal income tax treatment of this nature could affect the<br \/>\npurchase price that a holder would receive upon the sale of the notes.

This occurs when a particular<br \/>\nunderwriter repays to the underwriters a portion of the underwriting discount<br \/>\nreceived by it because the underwriting syndicate has repurchased notes sold by<br \/>\nor for the account of such underwriter in stabilizing or short covering<br \/>\ntransactions.<\/p>\n<p>These activities by the underwriters, as well as other purchases by the<br \/>\nunderwriters for their own accounts, may stabilize, maintain or otherwise affect<br \/>\nthe market prices of the notes. As a result, the prices of the notes may be<br \/>\nhigher than the prices that otherwise might exist in the open market. If<\/p>\n<p align=\"center\">S-13<\/p>\n<hr>\n<p>these activities are commenced, they may be discontinued by the underwriters<br \/>\nat any time without notice.

We may issue the senior debt securities under an indenture (the<br \/>\n&#8220;Senior Indenture&#8221;) to be entered into between us and The Bank of New York<br \/>\nMellon Trust Company, N.A., as trustee (&#8220;Senior Indenture Trustee&#8221;). The form of<br \/>\nSenior Indenture is included as an exhibit to the registration statement of<br \/>\nwhich this prospectus is a part.<\/p>\n<p>Below is a description of certain general terms of the senior debt<br \/>\nsecurities. The description is not complete and is subject to and qualified in<br \/>\nits entirety by reference to the Senior Indenture. The particular terms of a<br \/>\nseries of senior debt securities will be described in a prospectus supplement<br \/>\nand, if applicable, a pricing supplement. Capitalized terms used but not defined<br \/>\nin this summary have the meanings specified in the Senior Indenture.<\/p>\n<p>The senior debt securities will rank equally with all of our unsecured and<br \/>\nunsubordinated debt. The Senior Indenture is subject to the Trust Indenture Act<br \/>\nof 1939, as amended (the &#8220;Trust Indenture Act&#8221;). The Senior Indenture does not<br \/>\nlimit the amount of senior debt securities which we may issue, nor does it limit<br \/>\nus or our subsidiaries from issuing any other unsecured debt. Such other<br \/>\nunsecured debt may have different terms than the senior debt securities. Our<br \/>\npreviously issued and outstanding senior debt does have different terms than the<br \/>\nsenior debt securities (including different restrictive covenants and event of<br \/>\ndefault provisions). The terms of the senior debt securities issued under this<br \/>\nprospectus will only be as described in the Senior Indenture, this prospectus<br \/>\nand any prospectus supplement.<\/p>\n<p>Each prospectus supplement, together with a pricing supplement, if<br \/>\napplicable, will describe the terms relating to a series of senior debt<br \/>\nsecurities, which may include:<\/p>\n<\/p>\n<p>the title;<\/p>\n<\/p>\n<p>any limit on the amount that may be issued (unless expressly provided in the<br \/>\napplicable prospectus supplement or pricing supplement, a series of our senior<br \/>\ndebt securities may be re-opened from time to time for the issuance of<br \/>\nadditional senior debt securities of that series subject to any terms and<br \/>\nconditions set forth in or established pursuant to the Senior Indenture);<\/p>\n<\/p>\n<p>whether or not that series of senior debt securities will be issued as<br \/>\nregistered securities, bearer securities or both;<\/p>\n<\/p>\n<p>the price at which that series of senior debt securities will be issued,<br \/>\nwhich may be at a discount;<\/p>\n<\/p>\n<p>whether or not that series of senior debt securities will be issued in global<br \/>\nform and, if applicable, who the depositary will be;<\/p>\n<\/p>\n<p>the maturity date(s) or the method of determining the maturity date(s);<\/p>\n<\/p>\n<p>the person to whom any interest will be payable on any registered security,<br \/>\nif other than the person in whose name that security is registered at the close<br \/>\nof business on the regular record date;<\/p>\n<p align=\"center\">4<\/p>\n<hr>\n<p>the interest rate(s), if any, (which may be fixed or variable) or the method<br \/>\nfor determining the rate(s) and the date(s) interest will begin to accrue, the<br \/>\ndate(s) interest will be payable and the regular record date(s) for interest<br \/>\npayment date(s);<\/p>\n<\/p>\n<p>the place(s) where payments shall be payable, registered securities may be<br \/>\nsurrendered for registration of transfer, securities may be surrendered for<br \/>\nexchange, and notices and demands to or upon us may be served;<\/p>\n<\/p>\n<p>the period(s) within which, and the price(s) at which, that series of senior<br \/>\ndebt securities may, pursuant to any optional or mandatory redemption<br \/>\nprovisions, be redeemed, in whole or in part, and other related terms and<br \/>\nconditions;<\/p>\n<\/p>\n<p>any mandatory or optional sinking fund provisions or any provisions for<br \/>\nremarketing that series of senior debt securities and other related terms and<br \/>\nprovisions;<\/p>\n<\/p>\n<p>the denominations in which that series of senior debt securities will be<br \/>\nissued, if other than denominations of $1,000 in the case of registered<br \/>\nsecurities and any integral multiple thereof, and in the case of bearer<br \/>\nsecurities, if other than denominations of $5,000 and $100,000;<\/p>\n<\/p>\n<p>the currency or currencies, including composite currencies or currency units,<br \/>\nin which that series of senior debt securities may be denominated or in which<br \/>\npayment of the principal of and interest, if any, on that series of senior debt<br \/>\nsecurities shall be payable, if other than the currency of the United States of<br \/>\nAmerica, and, if so, whether that series of senior debt securities may be<br \/>\nsatisfied and discharged other than as provided in Article Four of the Senior<br \/>\nIndenture;<\/p>\n<\/p>\n<p>if the amounts of payments of principal of and interest on, if any, that<br \/>\nseries of senior debt securities are to be determined by reference to an index,<br \/>\nformula or other method, or based on a coin or currency other than that in which<br \/>\nthat series of senior debt securities are stated to be payable, the manner in<br \/>\nwhich such amounts shall be determined and the calculation agent, if any, with<br \/>\nrespect thereto;<\/p>\n<\/p>\n<p>if other than the principal amount thereof, the portion of the principal<br \/>\namount of that series of senior debt securities that will be payable upon<br \/>\ndeclaration of acceleration of the maturity thereof pursuant to an event of<br \/>\ndefault;<\/p>\n<\/p>\n<p>whether we will pay additional amounts on any of the senior debt securities<br \/>\nand coupons, if any, of the series to any non-United States holder in respect of<br \/>\nany tax, assessment or governmental charge withheld or deducted, and under what<br \/>\ncircumstances and with what procedures we will pay such additional amounts;<\/p>\n<\/p>\n<p>if other than as defined in the Senior Indenture, the meaning of &#8220;Business<br \/>\nDay&#8221;

Each such holder would generally be<br \/>\nsubject to tax liability in respect of interest income and original issue<br \/>\ndiscount, if applicable, thereon and would recognize any gain or loss upon any<br \/>\ndisposition, including redemption, of the assets held in trust. Although tax<br \/>\nmight be owed, the holder of a discharged senior debt security would not receive<br \/>\ncash (except for current payments of interest on that senior debt security)<br \/>\nuntil the maturity or earlier redemption (or, if applicable, repurchase by us at<br \/>\nthe option of the holder) of that senior debt security. United States federal<br \/>\nincome tax treatment of this nature could affect the purchase price that a<br \/>\nholder would receive upon the sale of the senior debt securities.
