**ABOUT OCCIDENTAL**

**Our Company**

Our principal businesses consist of three reporting segments: oil and gas, chemical and midstream and marketing. The oil and gas segment explores for, develops and produces oil (which includes condensate), NGL and natural gas. The chemical segment is operated by our subsidiary OxyChem, which mainly manufactures and markets basic chemicals and vinyls. The midstream and marketing segment purchases, markets, gathers, processes, transports and stores oil (which includes condensate), NGL, natural gas, carbon dioxide and power. It also optimizes its transportation and storage capacity, and invests in entities that conduct similar activities, such as Western Midstream Partners, L.P. ("WES").

The midstream and marketing segment also includes our low carbon ventures ("OLCV") businesses. OLCV seeks to leverage our legacy of carbon management expertise to develop carbon capture, utilization and storage projects, including the commercialization of direct air capture technology, and invests in other low-carbon technologies intended to reduce greenhouse gas emissions from our operations and strategically partner with other industries to help reduce their emissions.

**DESCRIPTION OF SENIOR DEBT SECURITIES**

**General**

We may issue one or more series of senior debt securities pursuant to this prospectus. We will issue the senior debt securities under that certain indenture (the "Senior Indenture"), dated as of August 8, 2019, between us and The Bank of New York Mellon Trust Company, N.A., as trustee ("Senior Indenture Trustee"). The Senior Indenture is included as an exhibit to the registration statement of which this prospectus is a part.

Below is a description of certain general terms of the senior debt securities. The description is not complete and is subject to and qualified in its entirety by reference to the Senior Indenture. The particular terms of a series of senior debt securities will be described in a prospectus supplement and, if applicable, a pricing supplement. Capitalized terms used but not defined in this summary have the meanings specified in the Senior Indenture.

The senior debt securities will rank equally with all of our unsecured and unsubordinated debt. The Senior Indenture is subject to the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"). The Senior Indenture does not limit the amount of senior debt securities which we may issue, nor does it limit us or our subsidiaries from issuing any other unsecured debt. Such other unsecured debt may have different terms than the senior debt securities. Our previously issued and outstanding senior debt may have different terms from the senior debt securities (including different restrictive covenants and event of default provisions). The terms of the senior debt securities issued under this prospectus will only be as described in the Senior Indenture, this prospectus and any prospectus supplement.

Each prospectus supplement, together with a pricing supplement, if applicable, will describe the terms relating to a series of senior debt securities, which may include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the title;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any limit on the amount that may be issued (unless expressly provided in the applicable prospectus supplement or pricing supplement, a series of our senior debt securities may be re-opened from time to time for the issuance of additional senior debt securities of that series, subject to the terms and conditions set forth in or established pursuant to the Senior Indenture);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the price at which that series of senior debt securities will be issued, which may be at a discount or a premium;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• whether or not that series of senior debt securities will be issued in global form and, if applicable, who the depositary will be;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the maturity date(s) or the method of determining the maturity date(s);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the person to whom any interest will be payable on any senior debt security, if other than the person in whose name that security is registered at the close of business on the regular record date;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the interest rate(s), if any (which may be fixed or variable), or the method for determining the rate(s) and the date(s) interest will begin to accrue, the date(s) interest will be payable and the regular record date(s) for interest payment date(s);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the place(s) where payments shall be payable, senior debt securities may be surrendered for registration of transfer, securities may be surrendered for exchange, and notices and demands to or upon us may be served;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the period(s) within which, and the price(s) at which, that series of senior debt securities may, pursuant to any optional or mandatory redemption provisions, be redeemed, in whole or in part, and other related terms and conditions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any mandatory or optional sinking fund provisions or any provisions for remarketing that series of senior debt securities and other related terms and provisions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if the amounts of payments of principal of and any interest on, that series of senior debt securities are to be determined by reference to an index, formula or other method, or based on a coin or currency other than that in which that series of senior debt securities are stated to be payable, the manner in which such amounts shall be determined and the calculation agent, if any, with respect thereto;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if other than the principal amount thereof, the portion of the principal amount of that series of senior debt securities that will be payable upon declaration of acceleration of the maturity thereof pursuant to an event of default;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• whether we will pay additional amounts on any of the senior debt securities and coupons, if any, of the series to any non-United States holder in respect of any tax, assessment or governmental charge withheld or deducted, and under what circumstances and with what procedures we will pay such additional amounts;

Each prospectus supplement or pricing supplement, as applicable, may describe certain United States federal income tax considerations applicable to the purchase, holding and disposition of the senior debt securities that the prospectus supplement or pricing supplement covers, as applicable.

**Limitation on Liens**

The Senior Indenture provides that we will not, nor will we 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 senior debt securities are secured equally and ratably with (or prior to) such Secured Debt. This covenant does not apply to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(6)Liens on any specific oil or gas property to secure Indebtedness incurred by us or any Consolidated Subsidiary to provide funds for all or any portion of the cost of exploration, production, gathering, processing, marketing, drilling or development of such property;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(7)Liens on any Principal Domestic Property (as defined below) securing Indebtedness incurred under industrial development, pollution control or other revenue bonds issued or guaranteed by the United States of America or any State thereof or any department, agency, instrumentality or political subdivision thereof;

Notwithstanding the foregoing, we and one or more Consolidated Subsidiaries may incur, create, assume, guarantee or otherwise become liable with respect to any Secured Debt that would otherwise be subject to the foregoing restrictions if, after giving effect thereto, the aggregate amount of all Secured Debt would not exceed 15% of Consolidated Net Tangible Assets (as defined below).

**Consolidation, Merger or Sale**

The Senior Indenture does not permit us to consolidate with, merge into or convey, transfer or lease our properties and assets substantially as an entirety to any Business Entity unless the following conditions are met:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the Business Entity formed by such consolidation or into which we are merged or the Business Entity that acquires by conveyance or transfer, or which leases, our properties and assets substantially as an entirety shall be a Business Entity organized and existing under the laws of the United States of America, any state thereof or the District of Columbia and shall expressly assume, by a supplemental indenture, all of our obligations under the Senior Indenture and the senior debt securities; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• immediately after giving effect to such transaction, no event of default, or event that, after notice or lapse of time or both, would become an event of default, shall have occurred and be continuing.

If the conditions described above are satisfied with respect to the senior debt securities, we will not need to obtain the approval of the holders in order to engage in such a consolidation, merger, conveyance, transfer or lease. Also, these conditions will apply only if we wish to consolidate with or merge into, or convey, transfer or lease our properties and assets substantially as an entirety to, another entity. We will not need to satisfy these conditions if we enter into other types of transactions, including any transaction in which we acquire the stock or assets of another entity and any transaction that involves a change of control of Occidental but in which we do not consolidate with or merge into another entity, as well as any transaction in which we convey, transfer or lease our properties and assets other than substantially as an entirety to a Business Entity.

**Reports**

The Senior Indenture provides that we will file with the Senior Indenture Trustee, within 15 days after we have filed the same with the United States Securities and Exchange Commission (the "Commission"), copies of the annual reports and of the information, documents and other reports (or copies of such portions of any of the foregoing as the Commission may from time to time by rules and regulations prescribe) which we may be required to file with the Commission pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934; *provided* that we will be deemed to have filed copies of any such annual reports, documents or other reports with the Senior Indenture Trustee to the extent that such annual reports, documents or other reports are filed with the Commission via EDGAR (or any successor electronic delivery procedure).

**Events of Default and Remedies Under the Senior Indenture**

The following are events of default under the Senior Indenture with respect to each series of senior debt securities:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• failure to pay any installment of interest upon any senior debt securities of such series when it becomes due and payable, and continuance of such failure to pay for a period of 30 days;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• failure to pay the principal of any senior debt securities of such series when due;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• failure to perform or breach of any other covenant or warranty contained in the senior debt securities or the Senior Indenture (other than a covenant or warranty specifically benefiting only another series of senior debt securities), and the continuance of such failure or breach for a period of 90 days after we receive notice of such failure or breach from the Senior Indenture Trustee or holders of at least 25% in principal amount of the outstanding senior debt securities of that series;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• certain events of bankruptcy, insolvency or reorganization relating to us; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any other event of default specified in the prospectus supplement or pricing supplement, if any, relating to that series of senior debt securities.

If an event of default with respect to senior debt securities of any series occurs and is continuing, the Senior Indenture Trustee or the holders of at least 25% in principal amount of the outstanding senior debt securities of that series, by notice in writing to us (and to the Senior Indenture Trustee if notice is given by such holders), may declare the principal of (or if such senior debt securities are Original Issue Discount Securities, the portion of the principal amount specified in the applicable prospectus supplement or pricing supplement, if any), and accrued interest, if any, on the senior debt securities of such series to be due and payable immediately. At any time after such a declaration of acceleration has been made and before a judgment or decree for payment of the money due has been obtained, holders of a majority in principal amount of the outstanding senior debt securities of that series, by written notice to us and the Senior Indenture Trustee, may rescind and annul such declaration and its consequences if:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• we have paid or deposited with the Senior Indenture Trustee a sum sufficient to pay all overdue installments of interest on the senior debt securities of that series, the principal of any senior debt securities of that series which has become due otherwise than by such declaration of acceleration and interest thereon, to the extent payment of such interest is lawful, interest on overdue installments of interest, all sums paid or advanced by the Senior Indenture Trustee, the reasonable compensation, expenses, disbursements and advances of the Senior Indenture Trustee, its agents and counsel and any other amount due to the Senior Indenture Trustee under the Senior Indenture, and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• all events of default with respect to outstanding senior debt securities of that series, other than the non-payment of the principal of and interest on such senior debt securities which became due solely by such declaration of acceleration, have been cured or waived in accordance with the terms of the Senior Indenture.

------

The holders of a majority in principal amount of the outstanding senior debt securities of any series may waive any past default with respect to that series and its consequences, except defaults regarding:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• payment of principal or interest; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• covenants that cannot be modified or amended without the consent of each holder of an outstanding senior debt security affected thereby (as described under "-Modification of Senior Indenture; Waiver" below).

Any waiver shall cure such default and the corresponding event of default.

Subject to the terms of the Senior Indenture, the Senior Indenture Trustee will be under no obligation to exercise any of its rights or powers under the Senior Indenture at the request or direction of any of the holders of the applicable series of senior debt securities, unless the holders have offered the Senior Indenture Trustee reasonable security or indemnity against costs, expenses and liabilities to be incurred in compliance with such request. The holders of a majority in principal amount of the outstanding senior debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Senior Indenture Trustee, or exercising any trust or power conferred on the Senior Indenture Trustee, with respect to the senior debt securities of that series; *provided* that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the direction given to the Senior Indenture Trustee is not in conflict with any law or the Senior Indenture;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the Senior Indenture Trustee may take any other action deemed proper by it which is not inconsistent with that direction; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the Senior Indenture Trustee has not determined that the action would be unjustly prejudicial to the holders not involved in the proceeding.

A holder of the senior debt securities of any series will have the right to institute a proceeding under the Senior Indenture or to appoint a receiver or trustee, or to seek other remedies only if:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the holder has given written notice to the Senior Indenture Trustee of a continuing event of default with respect to that series;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the holders of at least 25% in principal amount of the outstanding senior debt securities of that series have made written request, and have offered reasonable indemnity, to the Senior Indenture Trustee to institute the proceedings as trustee; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the Senior Indenture Trustee does not institute the proceeding, and does not receive from the holders of a majority in principal amount of the outstanding senior debt securities of that series other conflicting directions, within 60 days after the notice, request and offer of indemnity.

The Senior Indenture provides that no holder or group of holders of senior debt securities will have any right to affect, disturb or prejudice the rights of other holders, obtain or seek priority or preference over another holder or enforce its rights under the Senior Indenture except as provided in the Senior Indenture for the equal and ratable benefit of all holders.

These limitations on instituting proceedings do not apply to a suit instituted by a holder of senior debt securities to enforce the payment of the principal of or interest on the senior debt securities.

We will periodically deliver statements to the Senior Indenture Trustee regarding the existence or absence of defaults under the Senior Indenture.

------

We and the Senior Indenture Trustee may amend or supplement the Senior Indenture without the consent of any holders to, among other things:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• evidence and provide for the acceptance of appointment under the Senior Indenture of a successor Senior Indenture Trustee with respect to the senior debt securities of one or more series;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• add to, change or eliminate any provisions of the Senior Indenture (which addition, change or elimination may apply to one or more series of senior debt securities), *provided* that the addition, change or elimination neither (a) applies to any senior debt securities of any series created prior to the execution of the supplemental indenture that is entitled to the benefit of the provision nor (b) modifies the rights of holders of those senior debt securities with respect to those modified provisions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• add to or change or eliminate any provision of the Senior Indenture as shall be necessary to comply with any amendments to the Trust Indenture Act or to otherwise maintain qualification of the Senior Indenture under the Trust Indenture Act or to comply with the rules of any applicable depositary;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• change anything else that does not adversely affect the interests of any holder of senior debt securities in any material respect.

In addition, under the Senior Indenture, the rights of holders of any series of senior debt securities may be changed by us and the Senior Indenture Trustee with the written consent of (i) the holders of not less than a majority in principal amount of all outstanding debt securities issued under the Senior Indenture voting as a single class or (ii) if fewer than all of the series of outstanding debt securities issued under the Senior Indenture are affected by such addition, change, elimination or modification, the holders of not less than a majority in principal amount of the outstanding securities of all series so affected by such supplemental indenture voting as a single class (including, for the avoidance of doubt, consents obtained in connection with a purchase of, or tender offer or exchange for, such debt securities), to execute a supplemental indenture to add provisions to, or change in any manner or eliminate any provisions of, the Senior Indenture with respect to such applicable series of debt securities or modify in any manner the rights of the holders of such applicable series of debt securities under the Senior Indenture.

------

However, no change may be made without the consent of each holder of an outstanding senior debt security affected thereby if such change would, among other things:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• change the stated maturity of principal of, or any installment of principal or interest on, any such senior debt security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reduce the principal amount of, or the rate of interest on, or any premium payable on, any such senior debt security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reduce the percentage in principal amount of outstanding senior debt securities of any series the holders of which are required to consent to any such change, or the consent of whose holders is required for any waiver of compliance with certain provisions of the Senior Indenture or certain defaults thereunder and their consequences with respect to the senior debt securities of such series provided for in the Senior Indenture; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• modify any of the foregoing requirements or the provisions regarding waivers of any covenant or past default other than to increase the percentage of holders required for consent or waiver or add consent requirements for modification or waiver of other provisions.

**Form, Exchange and Transfer**

The senior debt securities of each series will be issued as registered securities. Unless otherwise specified in the applicable prospectus supplement or the pricing supplement, if any, senior debt securities will be issued in denominations of $2,000 and any integral multiple of $1,000 in excess thereof. Subject to the terms of the Senior Indenture and the limitations applicable to global securities described in the applicable prospectus supplement or the pricing supplement, if any, senior debt securities will be exchangeable for other senior debt securities of the same series, in any authorized denomination and of like tenor and aggregate principal amount.

Subject to the terms of the Senior Indenture and the limitations applicable to global senior debt securities set forth in the applicable prospectus supplement or pricing supplement, if any, senior debt securities issued may be presented for exchange or for registration of transfer (duly endorsed or with the form of transfer duly executed) at the office of the registrar or at the office of any transfer agent we designate for that purpose. Unless otherwise provided in the senior debt securities to be transferred or exchanged, no service charge will be made for any registration of transfer or exchange, but we may require payment of any taxes or other governmental charges. We have appointed the Senior Indenture Trustee as registrar. Any transfer agent (in addition to the registrar) initially designated by us for any senior debt securities will be named in the applicable prospectus supplement or pricing supplement. We may at any time designate additional transfer agents or rescind the designation of any transfer agent or approve a change in the office through which any transfer agent acts, except that we will be required to maintain a transfer agent in each place of payment for the senior debt securities of each series.

If the senior debt securities of any series are to be redeemed, we will not be required to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• issue, register the transfer of, or exchange any senior debt securities of, that series during a period beginning at the opening of business 15 days before any selection of senior debt securities for redemption and ending on the day of mailing or sending of the relevant notice of redemption; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• register the transfer of or exchange any senior debt securities so selected for redemption, in whole or in part, except the unredeemed portion of any senior debt security being redeemed in part.

**Global Senior Debt Securities**

The senior debt securities of each series may be issued in whole or in part in global form. A senior debt security in global form will be deposited with, or on behalf of, a depositary, which will be named in an applicable prospectus supplement or pricing supplement, if any. A global senior debt security shall be issued in registered form and in either temporary or definitive form. A global senior debt security may not be transferred, except as a whole, among the depositary for that senior debt security and its nominees and their respective successors. If any senior debt securities of a series are issuable as global senior debt securities, the applicable prospectus supplement or pricing supplement, if any, will describe any circumstances when beneficial owners of interests in that global senior debt security may exchange their interests for definitive senior debt securities of like series and tenor and principal amount in any authorized form and denomination.

**Discharge**

Unless otherwise indicated in an applicable prospectus supplement or pricing supplement, if any, we may terminate at any time our obligations under the Senior Indenture with respect to any series of senior debt securities (other than certain limited obligations, such as the obligation to transfer and exchange senior debt securities of that series) by (1)(a) delivering all of the outstanding senior debt securities of that series to the Senior Indenture Trustee to be cancelled or (b) depositing with the Senior Indenture Trustee in trust funds or non-callable United States government or government-guaranteed obligations sufficient without reinvestment to pay all remaining principal and interest on the series of senior debt securities and (2) complying with certain other provisions of the Senior Indenture.

------

If we elect to discharge our obligations by depositing cash or United States government or government guaranteed obligations as described above, under present law such discharge is likely to be treated for United States federal income tax purposes as a redemption of the senior debt securities of that series prior to maturity in exchange for the property deposited in trust. In that event, each holder would generally recognize, at the time of discharge, gain or loss for United States federal income tax purposes measured by the difference between (1) the sum of (a) the amount of any cash and (b) the fair market value of any property deposited in trust deemed received by such holder (unless attributable to accrued interest) and (2) such holder's tax basis in the senior debt securities deemed surrendered. After the discharge, each such holder would likely be treated as if it held an undivided interest in the cash (or investments made therewith) and the property held in trust (or investments made with interest received therefrom). Each such 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 senior debt security would not receive cash (except for current payments of interest on that senior debt security) until the maturity or earlier redemption (or, if applicable, repurchase by us at the option of the holder) of that senior debt security. United States federal income tax treatment of this nature could affect the purchase price that a holder would receive upon the sale of the senior debt securities. You are urged to consult with your tax advisor regarding the tax consequences of the discharge of our obligations.

**Information Concerning the Senior Indenture Trustee**

The Senior Indenture Trustee, other than during the occurrence and continuance of an event of default under the Senior Indenture, undertakes to perform only those duties as are specifically set forth in the Senior Indenture and, upon an event of default under the Senior Indenture, must use the same degree of care as a prudent person would exercise or use in the conduct of his or her own affairs. Subject to this provision, the Senior Indenture Trustee is under no obligation to exercise any of the rights or powers given it by the Senior Indenture at the request or direction of any holder of senior debt securities unless the Senior Indenture Trustee is offered reasonable security or indemnity by that holder against the costs, expenses and liabilities that it might incur. The Senior Indenture Trustee is not required to spend or risk its own money or otherwise become financially liable while performing its duties unless it reasonably believes that it will be repaid or receive adequate indemnity.

The Bank of New York Mellon is a participating lender under our revolving credit agreement and provides commercial banking services to us and our affiliates. The Bank of New York Mellon Trust Company, N.A. is the Senior Indenture Trustee and will also act as Subordinated Indenture Trustee. However, if The Bank of New York Mellon Trust Company, N.A. acquires any conflicting interest when an event of default is pending, it must (with certain exceptions) eliminate the conflict or resign.

**Payment and Payment Agents**

The person in whose name a senior debt security is registered will be treated as the owner of such security for the purpose of receiving payment of principal and, unless otherwise indicated in an applicable prospectus supplement or pricing supplement, if any, interest on such senior debt security and for all other purposes.

Unless otherwise indicated in the applicable prospectus supplement or pricing supplement, if any, payment of interest on any senior debt securities on any interest payment date will be made to the person in whose name those senior debt securities (or one or more predecessor securities) are registered at the close of business on the regular record date for the interest, except as otherwise provided by the procedures of the depositary. Unless otherwise indicated in the applicable prospectus supplement or pricing supplement, if any, principal and interest on the senior debt securities of a particular series will be payable at the office of the paying agents that we designate, except that payments of interest may, at our option, be made by wire transfer or check mailed to the address of the person entitled thereto.

We will be required to maintain a paying agent in each place of payment for the senior debt securities of a particular series. Unless otherwise indicated in the applicable prospectus supplement or pricing supplement, if any, the corporate trust office or agency of the Senior Indenture Trustee in The City of New York will be designated as the paying agent for payments with respect to senior debt securities.

------

All moneys that we pay to a paying agent or the Senior Indenture Trustee for the payment of the principal or interest, if any, on any senior debt securities which remain unclaimed at the end of two years after that principal or interest has become due and payable will be repaid to us, and the holder of the security thereafter may look only to us for payment thereof.

Unless otherwise indicated in an applicable prospectus supplement or pricing supplement, if any, interest shall be computed, for fixed rate securities, on the basis of a 360-day year comprised of twelve 30-day months, and, for variable rate securities, on the basis of the actual number of days in the interest period divided by 360.

**Governing Law**

The Senior Indenture and senior debt securities are governed by and construed in accordance with the law of the State of New York (without regard to conflicts of laws principles thereof).

**DESCRIPTION OF SUBORDINATED DEBT SECURITIES**

**General**

We may issue one or more series of subordinated debt securities pursuant to this prospectus. We may issue the subordinated debt securities under an indenture (the "Subordinated Indenture"), to be entered into in the future among us, the subsidiary guarantors of such debt securities, if any, and The Bank of New York Mellon Trust Company, N.A., or another entity, as trustee ("Subordinated Indenture Trustee"). The form of Subordinated Indenture is included as an exhibit to the registration statement of which this prospectus is a part.

Below is a description of certain general terms of the subordinated debt securities. The description is not complete and is subject to and qualified in its entirety by reference to the Subordinated Indenture. The particular terms of a series of subordinated debt securities will be described in a prospectus supplement and, if applicable, a pricing supplement. Capitalized terms used but not defined in this summary have the meanings specified in the Subordinated Indenture.

The subordinated debt securities will be unsecured and will be subordinated and junior in priority of payment to our Senior Indebtedness (as defined below). The Subordinated Indenture is subject to the Trust Indenture Act. The Subordinated Indenture does not limit the amount of Senior Indebtedness or subordinated debt securities which we may issue, nor does it limit us or our subsidiaries from issuing any debt.

Each prospectus supplement, together with a pricing supplement, if applicable, will describe the terms relating to a series of subordinated debt securities, which may include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the title;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any limit on the amount that may be issued (unless expressly provided in the applicable prospectus supplement or pricing supplement, a series of our subordinated debt securities may be re-opened from time to time for the issuance of additional subordinated debt securities of that series, subject to any terms and conditions set forth in or established pursuant to the Subordinated Indenture);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the price at which that series of subordinated debt securities will be issued, which may be at a discount or a premium;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• whether or not that series of subordinated debt securities will be issued in global form, and, if applicable, who the depositary will be;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the maturity date(s) or the method of determining the maturity date(s);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the person to whom any interest will be payable on any subordinated debt security, if other than the person in whose name that security is registered at the close of business on the regular record date;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the interest rate(s), if any (which may be fixed or variable), or the method for determining the rate(s) and the date(s) interest will begin to accrue, the date(s) interest will be payable and the regular record date(s) for interest payment date(s);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the place(s) where payments shall be payable, subordinated debt securities may be surrendered for registration of transfer, securities may be surrendered for exchange, and notices and demands to or upon us may be served;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the period(s) within which, and the price(s) at which, that series of subordinated debt securities may, pursuant to any optional or mandatory redemption provisions, be redeemed, in whole or in part, and other related terms and conditions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any mandatory or optional sinking fund provisions or any provisions for remarketing that series of subordinated debt securities and other related terms and provisions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the currency or currencies, including composite currencies or currency units, in which that series of subordinated debt securities may be denominated or in which payment of the principal of and interest, if any, on that series of subordinated debt securities shall be payable, if other than the currency of the United States of America, and, if so, whether that series of subordinated debt securities may be satisfied and discharged other than as provided in Article Four of the Subordinated Indenture;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if the amounts of payments of principal of and any interest on that series of subordinated debt securities are to be determined by reference to an index, formula or other method, or based on a coin or currency other than that in which that series of subordinated debt securities are stated to be payable, the manner in which such amounts shall be determined and the calculation agent, if any, with respect thereto;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if other than the principal amount thereof, the portion of the principal amount of that series of subordinated debt securities that will be payable upon declaration of acceleration of the maturity thereof pursuant to an event of default;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• whether we will pay additional amounts on any of the subordinated debt securities and coupons, if any, of the series to any non-United States holder in respect of any tax, assessment or governmental charge withheld or deducted, and under what circumstances and with what procedures we will pay such additional amounts;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if that series of subordinated debt securities may be issued or delivered (whether upon original issuance or upon exchange of a temporary security of such series or otherwise), or any installment of principal or interest is payable, only upon receipt of certain certificates or other documents or satisfaction of other conditions in addition to those specified in the Subordinated Indenture, the forms and terms of those certificates, documents or conditions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the right, if any, to extend the interest payment periods and the duration of the extensions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any other terms, which other terms may, subject, in the case of an existing outstanding series of subordinated debt securities, to the provisions of the Subordinated Indenture described below under "-Modification of Subordinated Indenture; Waiver," amend, supplement or replace any of the terms of the Subordinated Indenture insofar as it concerns the subordinated debt securities of that series.

Each prospectus supplement or pricing supplement, as applicable, may describe certain United States federal income tax considerations applicable to the purchase, holding and disposition of the subordinated debt securities that the prospectus supplement or pricing supplement covers, as applicable.

**Subordination**

The payment of the principal of, and premium, if any, and interest on, and any other amounts payable with respect to the subordinated debt securities will be subordinated, to the extent and in the manner set forth in the Subordinated Indenture, in right of payment to the prior payment in full of all Senior Indebtedness, whether such Subordinated Indebtedness is outstanding at the time such subordinated debt securities are issued or incurred thereafter. The Subordinated Indenture does not limit or prohibit us from incurring Senior Indebtedness. Holders of subordinated

------

debt securities should also recognize that contractual provisions in the Subordinated Indenture may prohibit us from making payments on the subordinated debt securities under specified circumstances.

"Senior Indebtedness" means the principal of, premium, if any, and interest on (including interest accruing after the filing of a petition initiating any proceeding pursuant to any Federal bankruptcy law or any other applicable Federal or State law, but only to the extent allowed or permitted to the holder of such Indebtedness of the Company against the bankruptcy or any other insolvency estate of the Company in such proceeding) and other amounts due on or in connection with any Indebtedness of the Company incurred, assumed or guaranteed by the Company, whether outstanding on the date of the Subordinated Indenture or thereafter incurred, assumed or guaranteed and all renewals, extensions and refundings of any such Indebtedness of the Company; *provided, however,* that the following will not constitute Senior Indebtedness:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)any of our Indebtedness as to which, in the instrument creating the same or evidencing the same or pursuant to which the same is outstanding, it is expressly provided that such Indebtedness shall be subordinated to or *pari passu* with the subordinated debt securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)Indebtedness of the Company in respect of the subordinated debt securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)any of our Indebtedness constituting trade accounts payable arising in the ordinary course of business;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)any of our Indebtedness initially issued to any Capital Trust (as defined below) in connection with an issuance by such Capital Trust of preferred securities or other securities similar to preferred securities; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)any of our Indebtedness owed to any of our subsidiaries.

"Indebtedness," as applied to a person, means, as of the date on which Indebtedness is to be determined and without duplication (i) all obligations represented by notes, bonds, debentures or similar evidences of indebtedness; (ii) all indebtedness for borrowed money or for the deferred purchase price of property or services other than, in the case of any such deferred purchase price, on normal trade terms; (iii) all rental obligations as lessee under leases which shall have been or should be, in accordance with generally accepted accounting principles, recorded as capital leases; and (iv) all Indebtedness of others for the payment of which such person is responsible or liable as obligor or guarantor.

"Capital Trust" means any Delaware business trust, or any other similar trust, or any partnership or other entity affiliated with us created for the purpose of issuing securities in connection with the issuance of subordinated debt securities under the Subordinated Indenture.

Even if the subordination provisions prevent us from making any payment when due on the subordinated debt securities of any series, we will be in default on our obligations under that series if we do not make the payment when due (subject to any applicable grace period). This means that the Subordinated Trustee and the holders of subordinated debt securities of that series can take action against us, but they will not receive any money until the claims of the holders of Senior Indebtedness have been fully satisfied.

*Payment Over of Proceeds Upon Dissolution, Etc.* The Subordinated Indenture provides that, upon any distribution of our assets in the event of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any insolvency or bankruptcy case or proceeding, or any receivership, liquidation, reorganization or other similar case or proceeding in connection therewith, relative to us or our creditors, as such, or to our assets, or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our liquidation, dissolution or other winding up, whether voluntary or involuntary and whether or not involving insolvency or bankruptcy, or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any assignment for the benefit of our creditors or any other marshalling of our assets and liabilities,

------

then and in such event:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)the holders of Senior Indebtedness shall be entitled to receive payment in full of all amounts due or to become due on or in respect of all Senior Indebtedness, or provision shall be made for such payment in cash, before the holders of the subordinated debt securities of any series are entitled to receive any payment on account of the principal amount, interest or any such other amounts as may be payable under the Subordinated Indenture, if any, in respect of the subordinated debt securities of such series; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)any payment or distribution of our assets of any kind or character, whether in cash, property or securities, by set-off or otherwise, to which the holders of the subordinated debt securities or the Subordinated Indenture Trustee would be entitled but for the subordination provisions of the Subordinated Indenture, including any such payment or distribution which may be payable or deliverable by reason of the payment of any other Indebtedness of the Company being subordinated to the payment of the securities of such series, shall be paid by the liquidating trustee or agent or other person making such payment or distribution, whether a trustee in bankruptcy, a receiver or liquidating trustee or otherwise, directly to the holders of Senior Indebtedness or their representative or representatives or to the trustee or trustees under any indenture under which any instruments evidencing any of such Senior Indebtedness may have been issued, ratably according to the aggregate amounts remaining unpaid on account of the principal of, and premium, if any, and interest on the Senior Indebtedness held or represented by each, to the extent necessary to make payment in full of all Senior Indebtedness remaining unpaid, after giving effect to any concurrent payment or distribution to the holders of such Senior Indebtedness.

In the event that, notwithstanding the provisions described in the preceding paragraph, the Subordinated Indenture Trustee or the holder of any subordinated debt security of any series receives any payment or distribution of our assets of any kind or character, whether in cash, property or securities, including any such payment or distribution which may be payable or deliverable by reason of the payment of any other Indebtedness of the Company being subordinated to the payment of the securities of such series, before all Senior Indebtedness is paid in full or payment thereof provided for, and if such fact has been made known to the Subordinated Indenture Trustee as provided in the Subordinated Indenture, or, as the case may be, such holder of subordinated debt securities, then and in such event such payment or distribution shall be paid over or delivered forthwith to the trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee, agent or other person making payment or distribution of our assets for application to the payment of all Senior Indebtedness remaining unpaid, to the extent necessary to pay all Senior Indebtedness in full, after giving effect to any concurrent payment or distribution to or for the holders of Senior Indebtedness.

By reason of such subordination, in the event of any distribution of our assets in connection with any insolvency, bankruptcy, receivership, liquidation, reorganization or other similar proceedings relating to us, or our liquidation, dissolution or winding up, or any assignment for the benefit of our creditors or other marshalling of our assets and liabilities:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• holders of Senior Indebtedness will be entitled to be paid in full before payments may be made on the subordinated debt securities and the holders of subordinated debt securities will be required to pay over their share of such distribution, to the extent made in respect of such subordinated debt securities, to the holders of Senior Indebtedness until such Senior Indebtedness is paid in full; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our creditors who are neither holders of subordinated debt securities nor holders of Senior Indebtedness may recover more, ratably, than the holders of the subordinated debt securities.

Furthermore, such subordination may result in a reduction or elimination of payments to the holders of subordinated debt securities.

Our consolidation with, or our merger into, another corporation or our liquidation or dissolution following the conveyance or transfer of our properties and assets substantially as an entirety to another person upon the terms and conditions described below under "-Consolidation, Merger or Sale," will not be deemed a dissolution, winding up, liquidation, reorganization, assignment for the benefit of creditors or marshalling of our assets and liabilities for the purposes of the subordination provisions of the Subordinated Indenture if the person formed by such consolidation

------

or into which we are merged or the person which acquires by conveyance or transfer our properties and assets substantially as an entirety, as the case may be, will, as a part of such consolidation, merger, conveyance or transfer, comply with the conditions described under "-Consolidation, Merger or Sale."

*Prior Payment to Senior Indebtedness upon Acceleration of Subordinated Debt Securities.* In the event that any subordinated debt securities of any series are declared due and payable before their stated maturity, the holders of Senior Indebtedness will be entitled to receive payment in full of all amounts due or to become due on or in respect of all Senior Indebtedness or provision will be made for such payment in cash, before the holders of the subordinated debt securities of such series are entitled to receive any payment from us on account of the principal, premium, interest or any other amounts that may be payable in respect of the subordinated debt securities of such series or on account of the purchase or other acquisition of subordinated debt securities of such series. In the event that we make any payment to the Subordinated Indenture Trustee or the holder of any subordinated debt securities of any series that is prohibited by the provisions described in the immediately preceding sentence, then such payment generally must be paid over and delivered to us by the person holding such payment for the benefit of the holders of Senior Indebtedness. The provisions described in this paragraph do not apply to any payment with respect to which the provisions described above under the caption "-Payment Over of Proceeds Upon Dissolution, Etc." would be applicable.

*Default in Senior Indebtedness.* In the event and during the continuation of any default by us in the payment of principal, premium, if any, interest or any other payment due on any of our Senior Indebtedness beyond any applicable grace period with respect thereto, or in the event that the maturity of any of our Senior Indebtedness has been accelerated because of a default, then, in any such case, no payment will be made by us with respect to the principal, premium, or interest or any other amounts that may be payable on the subordinated debt securities until such default is cured or waived or ceases to exist or any such acceleration or demand for payment has been rescinded.

*Other.* We are required to give prompt written notice to the Subordinated Indenture Trustee of any fact known to us which would prohibit the making of any payment in respect of the subordinated debt securities of any series.

If this prospectus is being delivered in connection with the offering of subordinated debt securities, the accompanying prospectus supplement or pricing supplement or information incorporated by reference herein will set forth the approximate amount of Senior Indebtedness outstanding as of a recent date.

**Consolidation, Merger or Sale**

The Subordinated Indenture generally permits us to consolidate with, merge into or convey, transfer or lease our properties and assets substantially as an entirety, to any person, so long as, immediately after giving effect to such transaction, no event of default under the Subordinated Indenture or event which, after notice or lapse of time or both, would become an event of default shall have occurred and be continuing. However, any successor or acquiror of such assets must assume all of our obligations under the Subordinated Indenture and the subordinated debt securities and be organized and existing under the laws of the United States of America, any state thereof or the District of Columbia.

**Events of Default Under the Subordinated Indenture**

The following are events of default under the Subordinated Indenture with respect to each series of subordinated debt securities:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• default in the payment of any installment of interest upon any subordinated debt security of such series when it becomes due and payable, and continuance of such default for a period of 30 days; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• default in the payment of the principal of any subordinated debt security of such series when due; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• default in the performance, or breach, of any covenant or warranty of the Company in the Subordinated Indenture (other than a covenant or warranty a default in whose performance or whose breach is specifically dealt with or which has been expressly included in the Subordinated Indenture solely for the

------

benefit of a series of subordinated debt securities other than such series), and continuance of such default or breach for a period of 90 days after there has been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in principal amount of the outstanding subordinated debt securities of such series a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a "Notice of Default" hereunder; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the entry of a decree or order by a court having jurisdiction in the premises adjudging the Company a bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment or composition of or in respect of the Company under Federal bankruptcy law or any other applicable Federal or State law, or appointing a receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or of any substantial part of its property, or ordering the winding up or liquidation of its affairs, and the continuance of any such decree or order unstayed and in effect for a period of 60 consecutive days; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the institution by the Company of proceedings to be adjudicated a bankrupt or insolvent, or the consent by it to the institution of bankruptcy or insolvency proceedings against it, or the filing by it of a petition or answer or consent seeking reorganization or relief under Federal bankruptcy law or any other applicable Federal or state law, or the consent by it to the filing of such petition or to the appointment of a receiver, liquidator, assignee, trustee, sequestrator or similar official of the Company or of any substantial part of its property, or the making by it of an assignment for the benefit of creditors, or the admission by it in writing of its inability to pay its debts generally as they become due, or the taking of corporate action by the Company in furtherance of any such action; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any other event designated as an event of default in the prospectus supplement or pricing supplement, if any, with respect to subordinated debt securities of that series.

If an event of default with respect to subordinated debt securities of any series occurs and is continuing, the Subordinated Indenture Trustee or the holders of not less than 25% in principal amount of the outstanding subordinated debt securities of that series, by notice in writing to us (and to the Subordinated Indenture Trustee if notice is given by such holders), may declare the principal of (or if such subordinated debt securities are discount securities, the portion of the principal amount specified in the applicable prospectus supplement or pricing supplement, if any), and accrued interest, if any, due and payable immediately. At any time after such a declaration of acceleration has been made and before a judgment or decree for payment of the money due has been obtained holders of a majority in principal amount of the outstanding subordinated debt securities of that series, by written notice to us and the Subordinated Indenture Trustee, may rescind and annul such declaration and its consequences if:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• we have paid or deposited with the Subordinated Indenture Trustee a sum sufficient to pay all overdue installments of interest on the subordinated debt securities of that series, the principal of any subordinated debt securities of that series which have become due otherwise than by such declaration of acceleration and interest thereon, to the extent payment of such interest is lawful, interest on overdue installments of interest, all sums paid or advanced by the Subordinated Indenture Trustee, the reasonable compensation, expenses, disbursements and advances of the Subordinated Indenture Trustee, its agents and counsel and any other amount due to the Subordinated Indenture Trustee under the Subordinated Indenture, and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• all events of default with respect to outstanding subordinated debt securities of that series, other than the non-payment of the principal of and interest on such subordinated debt securities which became due solely by such declaration of acceleration, have been cured or waived in accordance with the terms of the Subordinated Indenture.

The holders of a majority in principal amount of the outstanding subordinated debt securities of any series may waive any past default with respect to that series and its consequences, except defaults regarding:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• payment of principal or interest; or

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• covenants that cannot be modified or amended without the consent of the holder of each outstanding subordinated debt security of such series affected (as described under "-Modification of Subordinated Indenture; Waiver" below).

Any waiver shall cure such default and the corresponding event of default.

Subject to the terms of the Subordinated Indenture, the Subordinated Indenture Trustee will be under no obligation to exercise any of its rights or powers under the Subordinated Indenture at the request or direction of any of the holders of the applicable series of subordinated debt securities, unless the holders have offered the Subordinated Indenture Trustee reasonable security or indemnity against costs, expenses and liabilities to be incurred in compliance with such request. The holders of a majority in principal amount of the outstanding subordinated debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Subordinated Indenture Trustee, or exercising any trust or power conferred on the Subordinated Indenture Trustee, with respect to the subordinated debt securities of that series, *provided* that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the direction given to the Subordinated Indenture Trustee is not in conflict with any law or the Subordinated Indenture;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the Subordinated Indenture Trustee may take any other action deemed proper by it which is not inconsistent with that direction; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the Subordinated Indenture Trustee has not determined that the action would be unjustly prejudicial to the holders not involved in the proceeding.

A holder of the subordinated debt securities of any series will have the right to institute a proceeding under the Subordinated Indenture or to appoint a receiver or trustee, or to seek other remedies only if:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the holder has given written notice to the Subordinated Indenture Trustee of a continuing event of default with respect to the subordinated debt securities of that series;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the holders of not less than 25% in principal amount of the outstanding subordinated debt securities of that series have made written request, and have offered reasonable indemnity, to the Subordinated Indenture Trustee to institute the proceedings as trustee; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the Subordinated Indenture Trustee does not institute the proceeding, and does not receive from the holders of a majority in principal amount of the outstanding subordinated debt securities of that series other conflicting directions, within 60 days after the notice, request and offer of indemnity.

The Subordinated Indenture provides that no holder or group of holders of subordinated debt securities will have any right to affect, disturb or prejudice the rights of other holders, obtain or seek priority or preference over another holder or enforce its rights under the Subordinated Indenture except as provided in the Subordinated Indenture for the equal and ratable benefit of all holders.

These limitations on instituting proceedings do not apply to a suit instituted by a holder of subordinated debt securities to enforce the payment of the principal of or interest on the subordinated debt securities.

We will periodically file statements with the Subordinated Indenture Trustee regarding our compliance with the conditions and covenants in the Subordinated Indenture.

**Modification of Subordinated Indenture; Waiver**

We and the Subordinated Indenture Trustee may amend or supplement the Subordinated Indenture without the consent of any holders to, among other things:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• evidence the succession of another person and the assumption by such person of our covenants in the Subordinated Indenture and subordinated debt securities;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• add to our covenants, agreements and obligations for the benefit of the holders of all subordinated debt securities or any series thereof, or to surrender any right or power the Subordinated Indenture confers upon us;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• establish the form and terms of the subordinated debt securities of any series and (unless prohibited by the terms of the subordinated debt securities of any series pursuant to the Subordinated Indenture) to provide for the re-opening of a series of subordinated debt securities and for the issuance of additional subordinated debt securities of such series;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• evidence and provide for the acceptance of appointment under the Subordinated Indenture of a successor Subordinated Indenture Trustee with respect to the subordinated debt securities of one or more series;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• cure any ambiguity, to correct or supplement any provision in the Subordinated Indenture which may be inconsistent with any other provision in the Subordinated Indenture or make other provisions with respect to matters or questions arising under the Subordinated Indenture;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• add to, change or eliminate any provisions of the Subordinated Indenture (which addition, change or elimination may apply to one or more series of subordinated debt securities), *provided* that the addition, change or elimination neither (a) applies to any subordinated debt security of any series created prior to the execution of the supplemental indenture that is entitled to the benefit of the provision nor (b) modifies the rights of holders of those subordinated debt securities with respect to those modified provisions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• add to or change or eliminate any provision of the Subordinated Indenture as shall be necessary to comply with any amendments to the Trust Indenture Act or to otherwise maintain qualification of the Subordinated Indenture under the Trust Indenture Act or to comply with the rules of any applicable depositary;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• secure the subordinated debt securities; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• change anything else that does not adversely affect the interests of any holder of subordinated debt securities.

In addition, under the Subordinated Indenture, the rights of holders of a series of subordinated debt securities may be changed by us and the Subordinated Indenture Trustee with the written consent of the holders of at least a majority in principal amount of the outstanding subordinated debt securities of each series that is affected. However, no change may be made without the consent of the holder of each outstanding subordinated debt security affected if such change would, among other things:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• change the stated maturity of principal of, or any installment of principal or interest on, any such subordinated debt security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reduce the principal amount of a discount security payable upon declaration of acceleration;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reduce the principal amount of, or the rate of interest on, or reduce any premium payable on, any of the subordinated debt securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• change the place where, or currency in which, any principal of or interest on any such subordinated debt security is payable;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• impair the right to institute suit for the enforcement of any payment on or with respect to any of the subordinated debt securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• change the terms of the subordination of the subordinated debt securities in a manner adverse to the holders of any series of outstanding subordinated debt securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reduce the percentage in principal amount of outstanding subordinated debt securities of any series, the holders of which are required to consent to any such change, or the consent of whose holders is required for any waiver (of compliance with certain provisions of the Subordinated Indenture or certain defaults

------

thereunder and their consequences) with respect to the subordinated debt securities of such series provided for in the Subordinated Indenture; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• modify any of the foregoing requirements or the provisions regarding waivers of any covenant or past default other than to increase the percentage of holders required for consent or waiver or add consent requirements for modification of waiver or other provisions.

**Form, Exchange and Transfer**

The senior debt securities of each series will be issued as registered securities. Unless otherwise specified in the applicable prospectus supplement or the pricing supplement, if any, subordinated debt securities will be issued in denominations of $2,000 and any integral multiple of $1,000 in excess thereof. Subject to the terms of the Subordinated Indenture and the limitations applicable to global securities described in the applicable prospectus supplement or the pricing supplement, if any, subordinated debt securities will be exchangeable for other subordinated debt securities of the same series, in any authorized denomination and of like tenor and aggregate principal amount.

Subject to the terms of the Subordinated Indenture and the limitations applicable to global subordinated debt securities set forth in the applicable prospectus supplement or pricing supplement, if any, subordinated debt securities may be presented for exchange or for registration of transfer (duly endorsed or with the form of transfer duly executed) at the office of the registrar or at the office of any transfer agent we designate for that purpose. Unless otherwise provided in the subordinated debt securities to be transferred or exchanged, no service charge will be made for any registration of transfer or exchange, but we may require payment of any taxes or other governmental charges. We have appointed the Subordinated Indenture Trustee as registrar. Any transfer agent (in addition to the registrar) initially designated by us for any subordinated debt securities will be named in the applicable prospectus supplement or pricing supplement. We may at any time designate additional transfer agents or rescind the designation of any transfer agent or approve a change in the office through which any transfer agent acts, except that we will be required to maintain a transfer agent in each place of payment for the subordinated debt securities of each series.

If the subordinated debt securities of any series are to be redeemed, we will not be required to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• issue, register the transfer of, or exchange any subordinated debt securities of, that series during a period beginning at the opening of business 15 days before any selection of subordinated debt securities for redemption and ending on the day of mailing or sending of the relevant notice of redemption; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• register the transfer of or exchange any subordinated debt securities so selected for redemption, in whole or in part, except the unredeemed portion of any subordinated debt security being redeemed in part.

**Global Subordinated Debt Securities**

The subordinated debt securities of each series may be issued in whole or in part in global form. A subordinated debt security in global form will be deposited with, or on behalf of, a depositary, which will be named in an applicable prospectus supplement or pricing supplement, if any. A global subordinated debt security shall be issued in registered form in either temporary or definitive form. A global subordinated debt security may not be transferred, except as a whole among the depositary for that subordinated debt security and its nominees and their respective successors. If any subordinated debt securities of a series are issuable as global subordinated debt securities, the applicable prospectus supplement or pricing supplement, if any, will describe any circumstances when beneficial owners of interests in that global subordinated debt security may exchange their interests for definitive subordinated debt securities of like series and tenor and principal amount in any authorized form and denomination.

**Discharge**

Unless otherwise indicated in an applicable prospectus supplement or pricing supplement, if any, we may terminate at any time our obligations under the Subordinated Indenture with respect to any series of subordinated debt securities (other than certain limited obligations, such as the obligation to transfer and exchange subordinated debt

------

securities of that series) by (1)(a) delivering all of the outstanding subordinated debt securities of that series to the Subordinated Indenture Trustee to be cancelled or (b) depositing with the Subordinated Indenture Trustee in trust funds or non-callable United States government or government-guaranteed obligations sufficient without reinvestment to pay all remaining principal and interest on the series of subordinated debt securities and (2) complying with certain other provisions of the Subordinated Indenture.

If we elect to discharge our obligations by depositing cash or United States government or government guaranteed obligations as described above, under present law such discharge is likely to be treated for United States federal income tax purposes as a redemption of the subordinated debt securities of that series prior to maturity in exchange for the property deposited in trust. In that event, each holder would generally recognize, at the time of discharge, gain or loss for United States federal income tax purposes measured by the difference between (1) the sum of (a) the amount of any cash and (b) the fair market value of any property deposited in trust deemed received by such holder (unless attributable to accrued interest) and (2) such holder's tax basis in the subordinated debt securities deemed surrendered. After the discharge, each such holder would likely be treated as if it held an undivided interest in the cash (or investments made therewith) and the property held in trust (or investments made with interest received therefrom). Each such 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 subordinated debt security would not receive cash (except for current payments of interest on that subordinated debt security) until the maturity or earlier redemption (or, if applicable, repurchase by us at the option of the holder) of that subordinated debt security. United States federal income tax treatment of this nature could affect the purchase price that a holder would receive upon the sale of the subordinated debt securities. You are urged to consult with your tax advisor regarding the tax consequences of the discharge of our obligations.

**Information Concerning the Subordinated Indenture Trustee**

The Subordinated Indenture Trustee, other than during the occurrence and continuance of an event of default under the Subordinated Indenture, undertakes to perform only those duties as are specifically set forth in the Subordinated Indenture and, upon an event of default under the Subordinated Indenture, must use the same degree of care as a prudent person would exercise or use in the conduct of his or her own affairs. Subject to this provision, the Subordinated Indenture Trustee is under no obligation to exercise any of the rights or powers given it by the Subordinated Indenture at the request or direction of any holder of subordinated debt securities unless the Subordinated Indenture Trustee is offered reasonable security or indemnity by that holder against the costs, expenses and liabilities that it might incur. The Subordinated Indenture Trustee is not required to spend or risk its own money or otherwise become financially liable while performing its duties unless it reasonably believes that it will be repaid or receive adequate indemnity.

The Bank of New York Mellon is a participating lender under our revolving credit agreement and provides commercial banking services to us and our affiliates. The Bank of New York Mellon Trust Company, N.A. is the Subordinated Indenture Trustee and will also act as the Senior Indenture Trustee. However, if The Bank of New York Mellon Trust Company, N.A. acquires any conflicting interest when an event of default is pending, it must (with certain exceptions) eliminate the conflict or resign.

**Payment and Payment Agents**

The person in whose name a debt security subordinated is registered will be treated as the owner of such security for the purpose of receiving payment of principal and, unless otherwise indicated in an applicable prospectus supplement or pricing supplement, if any, interest on such subordinated debt security and for all other purposes.

Unless otherwise indicated in the applicable prospectus supplement or pricing supplement, if any, payment of interest on any subordinated debt securities on any interest payment date will be made to the person in whose name those subordinated debt securities (or one or more predecessor securities) are registered at the close of business on the regular record date for the interest, except as otherwise provided by the procedures of the depositary. Unless otherwise indicated in the applicable prospectus supplement or pricing supplement, if any, principal and interest on the subordinated debt securities of a particular series will be payable at the office of the paying agents that we

------

designate, except that payments of interest may, at our option, be made by wire transfer or check mailed to the address of the person entitled thereto.

We will be required to maintain a paying agent in each place of payment for the subordinated debt securities of a particular series. Unless otherwise indicated in the applicable prospectus supplement or pricing supplement, if any, the corporate trust office of the Subordinated Indenture Trustee in the City of New York will be designated as the paying agent for payments with respect to subordinated debt securities.

All moneys that we pay to a paying agent or the Subordinated Indenture Trustee for the payment of the principal or interest, if any, on any subordinated debt securities which remain unclaimed at the end of two years after that principal or interest has become due and payable will be repaid to us, and the holder of the security thereafter may look only to us for payment thereof.

Unless otherwise indicated in an applicable prospectus supplement or pricing supplement, if any, interest shall be computed, for fixed rate securities, on the basis of a 360-day year comprised of twelve 30-day months, and, for variable rate securities, on the basis of the actual number of days in the interest period divided by 360.

**Governing Law**

The Subordinated Indenture and subordinated debt securities will be governed by and construed in accordance with the law of the State of New York (without regard to conflicts of laws principles thereof).

**DESCRIPTION OF COMMON STOCK**

**General**

The following summary describes the material provisions of our common stock. The summary in this prospectus is not complete. We urge you to read our Restated Certificate of Incorporation of Occidental Petroleum Corporation, as amended ("Certificate of Incorporation"), and our Amended and Restated By-laws of Occidental Petroleum Corporation ("Bylaws"), which are incorporated herein by reference as exhibits to the registration statement of which this prospectus is a part.

Our Certificate of Incorporation authorizes our board of directors, without further stockholder action, to provide for the issuance of up to 1,500,000,000 shares of common stock, par value $0.20 per share. The common stock will, when issued, be fully paid and nonassessable.

Each prospectus supplement may describe certain United States federal income tax considerations applicable to the purchase, holding and disposition of the common stock that the prospectus supplement covers.

**Dividend Rights**

Subject to the dividend rights of the holders of any outstanding series of preferred stock, the holders of shares of common stock will be entitled to receive dividends when, as and if declared by our board of directors. We will pay those dividends either in cash, shares of common stock or otherwise, at the rate and on the date or dates as declared by our board of directors. Accruals of dividends will not bear interest. As a Delaware corporation, we are subject to statutory limitations on the declaration and payment of dividends.

**Liquidation Rights**

In the event of any voluntary or involuntary liquidation, dissolution or winding up of our affairs, holders of common stock will be entitled to share ratably in our assets that are legally available for distribution to stockholders after payment of liabilities, and after the payment in full of the amounts required to be paid to the holders of any outstanding class or series of preferred stock. Because we are a holding company, holders of common stock may not receive assets of our subsidiaries in the event of our liquidation until the claims of creditors of such subsidiaries are paid, except to the extent that we are a creditor of, and may have recognized claims against, such subsidiaries.

**Voting Rights**

Each holder of common stock entitled to vote will have one vote for each one share of common stock held on all matters to be voted upon by our stockholders, including elections of directors. Unless a different or minimum vote is required by applicable law, our Certificate of Incorporation, our Bylaws, the rules or regulations of any stock exchange applicable to us or any law or regulation applicable to us or our securities, in which case such different or minimum vote shall be the applicable vote on the matter, any question brought before any meeting of stockholders (other than the election of directors) will be decided by the affirmative vote of the holders of a majority in voting power of the shares present in person or by proxy at the meeting and entitled to vote on the subject matter. Directors will be elected by a majority of the votes cast, unless (a) the Secretary receives a notice that a stockholder has nominated one or more persons for election to the board of directors pursuant to our Bylaws and (b) each such nomination has not been withdrawn by such stockholder or such nominee on or prior to the date that is ten (10) days in advance of the date we file our definitive proxy statement (regardless of whether thereafter revised or supplemented) for such meeting of stockholders with the SEC, as a result of which the total number of nominees for director exceeds the number of directors to be elected at such meeting of stockholders, in which case the directors will be elected by the vote of a plurality of the votes cast.

**Conversion, Redemption and Preemptive Rights**

Holders of our common stock have no conversion, redemption, preemptive, subscription or similar rights.

------

**Anti-Takeover Effects of our Certificate of Incorporation and Bylaws and of Delaware Law**

Our Certificate of Incorporation and our Bylaws and Delaware law contain certain provisions that may have the effect of delaying, deferring or preventing a takeover attempt that a stockholder might consider in its best interest, including those attempts that result in a premium over the market price for the shares held by stockholders. Following is a description of certain of the anti-takeover effects of such provisions.

***Special Meetings of Stockholders.*** Our Certificate of Incorporation and Bylaws currently provide that special meetings of our stockholders may be called by our board of directors or the Chairman of our board of directors. In addition, subject to certain procedural requirements contained in our Certificate of Incorporation and Bylaws, special meetings of stockholders may be called by the Secretary upon the written request of record holders of at least 15% of our outstanding common stock.

***Advance Notice Requirements for Stockholder Proposals and Director Nominations.*** Our Bylaws provide that stockholders seeking to bring business before an annual meeting of stockholders, or to nominate candidates for election as directors at an annual or special meeting of stockholders, must provide timely notice to us thereof in writing within the time periods specified in our Bylaws. Our Bylaws also specify requirements as to the form and content of a stockholder's notice. These provisions may preclude some stockholders from bringing matters before the stockholders at an annual or special meeting or from making nominations for directors at an annual or special meeting.

***Stockholder Action by Written Consent.*** Stockholders are permitted to take action without a meeting by written consent, subject to certain procedures specified in our Certificate of Incorporation and Bylaws.

***Limitations on Stockholders' Ability to Change the Number of Directors.*** The number of directors to serve on our board of directors is fixed by our Bylaws, and, pursuant to our Bylaws, can only be changed by resolution of our directors. In addition, our Certificate of Incorporation provides that any vacancy on our board of directors (including any vacancy resulting from an increase in the number of directors) may be filled by a majority of our board of directors then in office. These provisions limit the ability of a stockholder to appoint new directors to our board of directors, and may have the effect of discouraging an attempt to obtain control of us by means of a proxy contest or otherwise.

***Authorized but Unissued Capital Stock.*** Our Certificate of Incorporation authorizes our board of directors to issue one or more series of preferred stock, and to determine, with respect to any such series of preferred stock, the number of shares to be included in any series and the designation, relative powers, preferences, rights and qualifications, limitations or restrictions of such series of preferred stock. The Delaware General Corporation Law (the "DGCL") does not require stockholder approval for any issuance of previously authorized shares of our capital stock. However, the listing requirements of the New York Stock Exchange ("NYSE"), which will apply so long as our common stock is listed on the NYSE, require stockholder approval of certain issuances of common stock or securities convertible into or exercisable for common stock equal to or exceeding 20% of the then outstanding voting power or then outstanding number of shares of our common stock. These additional shares may be used for a variety of corporate purposes, including future public offerings, to raise additional capital or to facilitate acquisitions.

One of the effects of the existence of unissued and unreserved common stock or preferred stock may be to enable our board of directors to issue shares to persons who support current management, which issuance could render more difficult or discourage an attempt to obtain control of us by means of a merger, tender offer, proxy contest or otherwise. In addition, provisions that could discourage an unsolicited tender offer or takeover proposal, such as extraordinary voting, dividend, redemption or conversion rights, could be included in a series of preferred stock.

***No Cumulative Voting.*** The DGCL provides that stockholders of a Delaware corporation are not entitled to the right to cumulate votes in the election of directors unless its certificate of incorporation provides otherwise. Our Certificate of Incorporation provides that holders of common stock do not have cumulative voting rights in the election of directors or otherwise. A cumulative voting provision could make it easier for minority stockholders to elect one or more directors to our board of directors.

------

***General Corporation Law of the State of Delaware.*** We are a Delaware corporation that is subject to Section 203 of the DGCL. Section 203 provides that, subject to certain exceptions specified in the law, a Delaware corporation shall not engage in certain "business combinations" with any "interested stockholder" for a three-year period following the time that the stockholder became an interested stockholder unless:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• prior to such time, the board of directors approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the corporation's voting stock outstanding at the time the transaction commenced, excluding certain shares; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• at or subsequent to that time, the business combination is approved by the board of directors of the corporation and by the affirmative vote of holders of at least 662/3% of the outstanding voting stock that is not owned by the interested stockholder.

A "business combination" includes certain mergers, asset or stock sales and other transactions involving the interested stockholder. Subject to certain exceptions, an "interested stockholder" is a person who, together with that person's affiliates and associates, owns (or within the previous three years did own) 15% or more of our voting stock.

Section 203 could prohibit or delay a merger or other takeover attempt and, accordingly, may discourage attempts to acquire us.

**Stock Exchange Listing**

Our common stock is listed on the NYSE under the symbol "OXY."

**Transfer Agent and Registrar**

EQ Shareowner Services acts as transfer agent and registrar for our common stock.

**DESCRIPTION OF PREFERRED STOCK**

**General**

The following summary describes the material provisions of our preferred stock. The summary in this prospectus is not complete. We urge you to read our Certificate of Incorporation and our Bylaws, which are incorporated herein by reference as exhibits to the registration statement of which this prospectus is a part, and the certificate of designations establishing a particular series of preferred stock which will be filed with the Secretary of State of the State of Delaware and the SEC in connection with the offering of the preferred stock.

Our Certificate of Incorporation authorizes our board of directors, without further stockholder action, to provide for the issuance of up to 50,000,000 shares of preferred stock, par value $1.00 per share, in one or more series, and to fix the number of shares to be included in any series and the designation, relative powers, preferences and rights and qualifications, limitations or restrictions of all shares of such series.

The particular terms of any series of preferred stock that we offer under this prospectus will be described in the applicable prospectus supplement relating to that series of preferred stock. Those terms may include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the number of shares of any series and the designation to distinguish the shares of such series from the shares of all other series;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the purchase price of the preferred stock;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the voting powers, if any, and whether such voting powers are full or limited, in any such series;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the redemption provisions, if any, applicable to such series, including the redemption price or prices to be paid;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• whether dividends, if any, shall be cumulative or noncumulative, the dividend rate, or method of determining the dividend rate of such series, and the dates and preferences of dividends on such series;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the rights of such series upon our voluntary or involuntary dissolution, or upon any distribution of our assets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the provisions, if any, pursuant to which the shares of such series are convertible into, or exchangeable for, shares of any other class or classes or of any other series of the same or any other class or classes of stock, or any other security, of ours or any other corporation, and the price or prices or the rates of exchange applicable thereto;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the right, if any, to subscribe for or to purchase any securities of ours or any other corporation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the provisions, if any, of any sinking fund applicable to such series; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any other relative, participating, optional or other special powers, preferences, rights, qualifications, limitations or restrictions thereof.

Each prospectus supplement may describe certain United States federal income tax considerations applicable to the purchase, holding and disposition of the preferred stock that the prospectus supplement covers.

If the terms of any series of preferred stock being offered differ from the terms set forth in this prospectus, those terms will also be disclosed in the applicable prospectus supplement relating to that series of preferred stock.

The preferred stock will, when issued, be fully paid and nonassessable.

**Dividend Rights**

The preferred stock will be preferred over the common stock as to payment of dividends. Before any dividends or distributions (other than dividends or distributions payable in common stock or other stock ranking junior to that

------

series of preferred stock as to dividends and upon liquidation) on the common stock or other stock ranking junior to that series of preferred stock as to dividends and upon liquidation shall be declared and set apart for payment or paid, the holders of shares of each series of preferred stock (unless otherwise set forth in the applicable prospectus supplement) will be entitled to receive dividends when, as and if declared by our board of directors or, if dividends are cumulative, full cumulative dividends for the current and all prior dividend periods. We will pay those dividends either in cash, shares of preferred stock, or otherwise, at the rate and on the date or dates set forth in the applicable prospectus supplement. With respect to each series of preferred stock that has cumulative dividends, the dividends on each share of the series will be cumulative from the date of issue of the share unless some other date is set forth in the prospectus supplement relating to the series. Accruals of dividends will not bear interest. The applicable prospectus supplement will indicate the relative ranking of the particular series of the preferred stock as to the payment of dividends, as compared with then-existing and future series of preferred stock.

**Rights Upon Liquidation**

The preferred stock of each series will be preferred over the common stock and other stock ranking junior to that series of preferred stock as to assets, so that the holders of that series of preferred stock (unless otherwise set forth in the applicable prospectus supplement) will be entitled to be paid, upon our voluntary or involuntary liquidation, dissolution or winding up, and before any distribution is made to the holders of common stock and other stock ranking junior to that series of preferred stock, the amount set forth in the applicable prospectus supplement. If upon any liquidation, dissolution or winding up, our net assets are insufficient to permit the payment in full of the respective amounts to which the holders of all outstanding preferred stock are entitled, our entire remaining net assets will be distributed among the holders of each series of preferred stock in amounts proportional to the full amounts to which the holders of each series are entitled, subject to the relative rankings of each series of preferred stock upon liquidation. The applicable prospectus supplement will indicate the relative ranking of the particular series of the preferred stock upon liquidation, as compared with then-existing and future series of preferred stock. Unless otherwise specified in a prospectus supplement for a series of preferred stock, after payment of the full amount of the liquidating distribution to which they are entitled, the holders of shares of preferred stock will not be entitled to any further participation in any distribution of our assets.

**Conversion, Redemption or Exchange**

The shares of a series of preferred stock will be convertible or exchangeable at the option of the holder of the preferred stock, redeemable at our option or at the option of the holder, as applicable, convertible or exchangeable at our option, into another security, in each case, to the extent set forth in the applicable prospectus supplement.

**Voting Rights**

The holders of each series or class of preferred stock we may issue will have no voting rights, except as required by law and as described below or in the applicable prospectus supplement. Our Board of Directors may, upon issuance of a series or class of preferred stock, grant voting rights to the holders of that series or class, which may be full or limited.

Without the affirmative vote of a majority of the shares of any class of preferred stock then outstanding, we may not:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• increase or decrease the aggregate number of authorized shares of that class;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• increase or decrease the par value of the shares of that class; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• alter or change the powers, preferences or special rights of the shares of that class so as to affect them adversely.

If the amendment would adversely alter or change the powers, preferences or special rights of one or more series of a class of preferred stock, but not the entire class, then only the shares of the affected series will have the right to vote on the amendment.

------

**Other**

Our Certificate of Incorporation and our Bylaws and Delaware law contain certain provisions that may have the effect of delaying, deferring or preventing a takeover attempt that a holder of our preferred stock or depositary shares might consider in its best interest, including those attempts that may result in a premium over the market price of those shares. See "Description of Common Stock-Anti-Takeover Effects of our Certificate of Incorporation and Bylaws and of Delaware Law."

------

**DESCRIPTION OF WARRANTS**

We may issue warrants to purchase any combination of our debt securities, common stock, preferred stock or other securities. We may issue warrants independently or together with other securities. Warrants sold with other securities may be attached to or separate from the other securities. We will issue warrants under one or more warrant agreements between us and a warrant agent that we will name in the prospectus supplement.

The applicable prospectus supplement will include specific terms relating to the offering. We will file the form of any warrant agreement with the SEC, and you should read the warrant agreement for provisions that may be important to you. The prospectus supplement will include some or all of the following terms:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the title of the warrants;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the aggregate number of warrants offered;

------

**DESCRIPTION OF DEPOSITARY SHARES**

The following description of the terms of the depositary shares sets forth certain general terms and provisions of the depositary shares to which any prospectus supplement may relate. The particular terms of the depositary shares offered by any prospectus supplement and the extent, if any, to which these general provisions may apply to those depositary shares will be described in the prospectus supplement relating to those depositary shares. Accordingly, for a description of the terms of a particular issue of depositary shares, reference must be made to both the prospectus supplement relating thereto and to the following description.

**General**

We may, at our option, elect to offer shares of preferred stock represented by depositary shares. The shares of any series of the preferred stock underlying the depositary shares will be deposited under a separate deposit agreement between us and one or more depositaries selected by us, who we will name in the prospectus supplement.

Subject to the terms of the deposit agreement, each holder of a depositary share will be entitled, proportionately, to all the rights, preferences and privileges of the preferred stock represented by that depositary share, including dividend, voting, redemption, conversion, exchange and liquidation rights. The depositary shares will be evidenced by depositary receipts issued under the deposit agreement. Each receipt will represent the applicable interest in a number of shares of a particular series of the preferred stock, which we will describe in the prospectus supplement.

A holder of depositary shares will be entitled to receive the whole number of shares of preferred stock underlying those depositary shares. Holders will not be entitled to receive fractional shares. If the depositary receipts delivered by the holder evidence a number of depositary shares in excess of the whole number of shares to be withdrawn, the depositary will deliver to that holder at the same time a new depositary receipt for the excess number of depositary shares.

------

**DESCRIPTION OF STOCK PURCHASE CONTRACTS AND STOCK PURCHASE UNITS**

We may issue stock purchase contracts, including contracts obligating holders to purchase from us, and us to sell to the holders, or for us to issue in exchange for other securities, a specified number of shares of our common stock or preferred stock (or a range of numbers of shares in accordance with a predetermined formula) at a future date or dates or upon the occurrence of specified events. The price per share of common stock or preferred stock may be fixed at the time the stock purchase contracts are issued or may be determined by reference to a specific formula set forth in the stock purchase contracts.

We may issue the stock purchase contracts separately or as a part of units, often known as stock purchase units, consisting of a stock purchase contract and any combination of our senior debt securities or subordinated debt securities or any other security registered under this registration statement as described in the applicable prospectus supplement, securing the holder's obligations to purchase the common stock or preferred stock under the stock purchase contracts.

The stock purchase contracts may require us to make periodic payments to the holders of the stock purchase units or vice versa, and those payments may be unsecured or prefunded on some basis. The stock purchase contracts may require holders to secure their obligations in a specified manner, and in specified circumstances, we may deliver newly issued prepaid stock purchase contracts, often known as prepaid securities, upon release to a holder of any collateral securing that holder's obligations under the original stock purchase contract.

The applicable prospectus supplement will describe the terms of any stock purchase contracts or stock purchase units and, if applicable, prepaid securities. That description will not be complete. For more information, you should review the stock purchase contracts and, if applicable, the collateral arrangements and depositary arrangements relating to those stock purchase contracts or stock purchase units and any prepaid securities and the document under which the prepaid securities will be issued. We will file forms of these documents with the SEC before we issue any stock purchase contracts or stock purchase units and, if applicable, prepaid securities.

------

**DESCRIPTION OF UNITS**

As specified in the applicable prospectus supplement, we may issue units comprised of two or more of the other securities described in this prospectus in any combination. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security. The applicable prospectus supplement will describe:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the designation and terms of the units and of the securities comprising the units, including whether and under what circumstances the securities comprising the units may be held or transferred separately;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a description of the terms of any unit agreement governing the units;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a description of the provisions for the payment, settlement, transfer or exchange of the units; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• whether the units will be issued in fully registered or global form.

The unit agreement, together with the terms of the underlying securities, will be filed with the SEC in connection with the offering of the specific units.

------

**PLAN OF DISTRIBUTION**

We may sell the securities in and outside the United States through underwriters or dealers, directly to purchasers, through agents or a combination of these methods.

**Sale Through Underwriters or Dealers**

If we use underwriters in the sale of securities, the underwriters will acquire the securities for their own account. The underwriters may resell the securities from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. Underwriters may offer securities to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. Unless we inform you otherwise in a prospectus supplement, the obligations of the underwriters to purchase the securities will be subject to conditions, and the underwriters will be obligated to purchase all the securities if they purchase any of them. The underwriters may change from time to time any initial public offering price and any discounts or concessions allowed or re-allowed or paid to dealers.

During and after an offering through underwriters, the underwriters may purchase and sell the securities in the open market. These transactions may include overallotment and stabilizing transactions and purchases to cover syndicate short positions created in connection with the offering. The underwriters may also impose a penalty bid, whereby selling concessions allowed to syndicate members or other broker-dealers for the offered securities sold for their account may be reclaimed by the syndicate if such offered securities are repurchased by the syndicate in stabilizing or covering transactions. These activities may stabilize, maintain or otherwise affect the market price of the offered securities, which may be higher than the price that might otherwise prevail in the open market. If commenced, these activities may be discontinued at any time.

If we use dealers in the sale of securities, we will sell the securities to them as principals. They may then resell those securities to the public at varying prices determined by the dealers at the time of resale. The dealers participating in any sale of the securities may be deemed to be underwriters within the meaning of the Securities Act with respect to any sale of those securities. We will include in the prospectus supplement the names of the dealers and the terms of the transaction.

**Direct Sales and Sales Through Agents**

We may sell the securities directly. In that event, no underwriters or agents would be involved. We may also sell the securities through agents we designate from time to time. In a prospectus supplement, we will name any agent involved in the offer or sale of the securities, and we will describe any commissions payable by us to the agent.

Unless we inform you otherwise in such prospectus supplement, any agent will agree to use its reasonable best efforts to solicit purchases for the period of its appointment.

We may sell the securities directly to institutional investors or others who may be deemed to be underwriters within the meaning of the Securities Act with respect to any sale of those securities. We will describe the terms of any such sales in a prospectus supplement.

**Delayed Delivery Contracts**

If we so indicate in a prospectus supplement, we may authorize agents, underwriters or dealers to solicit offers from certain types of institutions to purchase securities from us at the public offering price under delayed delivery contracts. These contracts would provide for payment and delivery on a specified date in the future. The contracts would be subject only to those conditions described in such prospectus supplement. Such prospectus supplement will describe the commission payable for solicitation of those contracts.

**General Information**

We may have agreements with the agents, dealers and underwriters to indemnify them against civil liabilities, including liabilities under the Securities Act, or to contribute with respect to payments that the agents, dealers or

------

underwriters may be required to make. Agents, dealers and underwriters may engage in transactions with us or perform services for us in the ordinary course of their businesses.

------

**LEGAL MATTERS**

Unless otherwise indicated in the applicable prospectus supplement, the validity of the securities offered under this prospectus will be passed upon for us by Cravath, Swaine & Moore LLP, New York, New York. Additional legal matters may be passed on for us, or any underwriters, dealers or agents, by counsel we will name in the applicable prospectus supplement.

__________________

\*Under Rules 456(b) and 457(r) of the Securities Act, applicable SEC registration fees have been deferred and will be paid at the time of any particular offering of securities under this registration statement, and are therefore not estimable at this time. Excludes registration fees of $107,751.68 that were previously paid by the registrant relating to the Carry-Forward Securities previously registered pursuant to a prospectus supplement, filed with the SEC on March 3, 2025, to the registration statement on Form S-3 (File No. 333-266420) (the "Prior Registration Statement"). The Prior Registration Statement was filed with the SEC and became automatically effective on July 29, 2022. Pursuant to Rule 415(a)(6) under the Securities Act, the registration fee relating to the Carry-Forward Securities under the Prior Registration Statement will continue to be applied to such securities hereunder.

\*\*Because an indeterminate amount of securities is covered by this registration statement, the expenses in connection with the issuance and distribution of the securities are not currently determinable.

**Item 15. Indemnification of Directors and Officers.**

Section 145 of the DGCL permits a corporation to indemnify its directors and officers against expenses (including attorneys' fees), judgments, fines and amounts paid in settlements actually and reasonably incurred by them in connection with any action, suit or proceeding brought by third parties. The directors or officers must have acted in good faith and in a manner they reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe their conduct was unlawful. In a derivative action, an action only by or in the right of the corporation, indemnification may be made only for expenses actually and reasonably incurred by directors and officers in connection with the defense or settlement of an action or suit, and only with respect to a matter as to which they shall have acted in good faith and in a manner they reasonably believed to be in or not opposed to the best interests of the corporation. No indemnification shall be made with respect to any claim, issue or matter as to which such person shall have been adjudged liable to the corporation, unless and only to the extent that the court in which the action or suit was brought shall determine upon application that the defendant officers or directors are fairly and reasonably entitled to indemnity for such expenses despite such adjudication of liability and in view of all of the circumstances of the case.

Occidental has adopted provisions in its Bylaws, as amended, which provide that it will indemnify, to the fullest extent permitted by applicable law as it presently exists or may hereafter be amended, any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, other than an action by Occidental or in its right, by reason of the fact that such person is or was Occidental's director or officer, or is or was serving at Occidental's request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust, nonprofit entity or other enterprise, against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, but in each case only if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful.

------

Occidental's Bylaws, as amended, further state that this indemnification shall not be deemed exclusive of any other right to which the indemnified person may be entitled, and shall continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of the heirs, executors and administrators of that person.

Occidental's restated certificate of incorporation, as amended, provides that, consistent with Section 102(b)(7) of the DGCL, no director shall be liable to Occidental or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• for any breach of the director's duty of loyalty to Occidental or its stockholders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• for acts or omissions not in good faith or which involve intentional misconduct or knowing violation of the law;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• under Section 174 of the DGCL; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• for any transaction from which a director derived an improper benefit.

Occidental maintains policies insuring its officers and directors against certain civil liabilities, including liabilities under the Securities Act.

Occidental also entered into indemnification agreements with each of its directors and certain of its executive officers and anticipates that it will enter into similar agreements with future directors and officers. Generally, these agreements attempt to provide the maximum protection permitted by Delaware law with respect to indemnification. The indemnification agreements provide that Occidental will pay certain amounts incurred by its directors in connection with any civil, criminal, administrative or investigative action or proceeding. Such amounts include any expenses, including attorney's fees, judgments, civil or criminal fines, settlement amounts and other expenses customarily incurred in connection with legal proceedings.

**Item 17. Undertakings.**

(a)The undersigned registrant hereby undertakes:

&nbsp;&nbsp;&nbsp;&nbsp;(1)To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)To include any prospectus required by Section 10(a)(3) of the Securities Act;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii)To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

*provided, however,* that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

&nbsp;&nbsp;&nbsp;&nbsp;(2)That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

&nbsp;&nbsp;&nbsp;&nbsp;(3)To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

&nbsp;&nbsp;&nbsp;&nbsp;(4)That, for the purpose of determining liability under the Securities Act to any purchaser:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial *bona fide* offering thereof, *provided, however*, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or

------

prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

&nbsp;&nbsp;&nbsp;&nbsp;(5)That, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii)The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv)Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(b)The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant's annual report pursuant to Sections 13(a) or 15(d) of the Securities Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c)Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

(e)The undersigned registrant hereby undertakes to file an application for the purpose of determining the eligibility of the Trustee to act under subsection (a) of Section 310 of the Trust Indenture Act, in accordance with the rules and regulations prescribed by the SEC under Section 305(b)(2) of the Trust Indenture Act.

(the "<u>Senior Debt Trustee</u>"), which is filed as an exhibit to the Registration Statement; subordinated debt securities (the "<u>Subordinated Debt Securities</u>") of the Company, which may be issued under an indenture (the "<u>Subordinated Debt Indenture</u>") to be entered into between the Company and The Bank of New York Mellon Trust Company, N.A. (the "<u>Subordinated Debt Trustee</u>"), a form of which is filed as an exhibit to the Registration Statement; preferred stock, par value $1.00 per share (the "<u>Preferred Stock</u>"), of the Company, including Preferred Stock as may from time to time be issued upon conversion of Senior Debt Securities; common stock, par value $0.20 per share (the "<u>Common Stock</u>"), of the Company, including Common Stock as may from time to time be issued upon conversion of Senior Debt Securities, Preferred Stock or the exercise of Warrants (as defined below); warrants to purchase Senior Debt Securities, Subordinated Debt Securities, Preferred Stock, Common Stock or other Securities (other than Warrants) (collectively, the "<u>Warrants</u>") of the Company; depositary shares representing fractional or multiple shares of Preferred Stock (the "<u>Depositary Shares</u>") of the Company; stock purchase contracts of the Company (the "<u>Stock Purchase Contracts</u>"); stock purchase units of the Company (the "<u>Stock Purchase Units</u>"); and units of a combination of one or more of the Senior Debt Securities, Subordinated Debt Securities, Preferred Stock, Common Stock, Warrants, Depositary Shares, Stock Purchase Contracts or Stock Purchase Units (collectively, the "<u>Units</u>"). The Senior Debt Securities, the Subordinated Debt Securities, the Preferred Stock, the Common Stock, the Warrants, the Depositary Shares, the Stock Purchase Contracts, the Stock Purchase Units and the Units are collectively referred to herein as the "<u>Securities</u>".

In connection with this opinion, we have examined originals, or copies certified or otherwise identified to our satisfaction, of such corporate records, certificates of corporate officers and government officials and such other documents as we have deemed necessary or appropriate for the purposes of this opinion, including: (a) the Restated Certificate of Incorporation of the Company; (b) the Amended and Restated Bylaws of the Company; (c) resolutions adopted by the Board of Directors of the Company on July 1, 2025; (d) the Registration Statement; (e) the

Senior Debt Indenture; and (f) the Subordinated Debt Indenture. As to various questions of fact material to this opinion, we have relied upon representations of officers or directors of the Company and documents furnished to us by the Company without independent verification of their accuracy.

We also express no opinion as to (i) the enforceability of the provisions of the Senior Debt Indenture, the Subordinated Debt Indenture, the Senior Debt Securities, the Subordinated Debt Securities, the Warrants, Stock Purchase Contracts, Stock Purchase Units or Units to the extent that such provisions constitute a waiver of illegality as a defense to performance of contract obligations or any other defense to performance which cannot, as a matter of law, be effectively waived or (ii) whether a state court outside the State of New York or a Federal court of the United States would give effect to the choice of New York law provided for therein.

Courts in the United States have not customarily rendered judgments for money damages denominated in any currency other than United States dollars. Section 27(b) of the Judiciary Law of the State of New York provides, however, that a judgment or decree in an action based upon an obligation denominated in a currency other than United States dollars shall be rendered in the foreign currency of the underlying obligation and converted into United States dollars at the rate of exchange prevailing on the date of the entry of the judgment or decree. We express no opinion as to whether a Federal court of the United States would render a judgment other than in United States dollars.

We are admitted to practice only in the State of New York and express no opinion as to matters governed by any laws other than the laws of the State of New York, the Delaware General Corporation Law and the Federal laws of the United States of America.
