We have not authorized anyone to provide any information other than that contained or incorporated by reference in this prospectus, in any prospectus supplement or in any free writing prospectus prepared by or on behalf of us or to which we have referred you. We take no responsibility for, and can provide no assurance as to the reliability of, any other information that others may give you. This prospectus is not an offer to sell, nor is it an offer to buy, these securities in any state where the offer or sale is not permitted. The information in this prospectus is complete and accurate as of the date on the front cover of this prospectus, but our business, financial condition or results of operations may have changed since that date.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This prospectus includes “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”) and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). You can identify our forward-looking statements by the words “anticipate,” “estimate,” “believe,” “continue,” “could,” “intend,” “may,” “plan,” “potential,” “predict,” “should,” “will,” “expect,” “objective,” “projection,” “forecast,” “goal,” “guidance,” “outlook,” “effort,” “target” and similar expressions.

We based forward-looking statements on our current expectations, estimates and projections of our business and the industries in which we operate. We caution you that these statements are not guarantees of future performance. They involve assumptions about future events that, while made in good faith, may prove to be incorrect, and involve risks and uncertainties we cannot predict. Our actual outcomes and results may differ materially from what we have expressed or forecast in the forward-looking statements. Any differences could result from a variety of factors, including the following:

•

the cost of raw materials represents a substantial portion of our operating expenses, and energy costs generally follow price trends of crude oil, natural gas liquids and/or natural gas; price volatility can significantly affect our results of operations and we may be unable to pass raw material and energy cost increases on to our customers due to the significant competition that we face, the commodity nature of our products and the time required to implement pricing changes;

•

our operations in the United States (“U.S.”) have benefited from low-cost natural gas and natural gas liquids; decreased availability of these materials (for example, from their export or regulations impacting hydraulic fracturing in the U.S.) could reduce the current benefits we receive;

•

if crude oil prices are low relative to U.S. natural gas prices, we could see less benefit from low-cost natural gas and natural gas liquids and it could have a negative effect on our results of operations;

•

industry production capacities and operating rates may lead to periods of oversupply and low profitability;

•

we may face unplanned operating interruptions (including leaks, explosions, fires, weather-related incidents, mechanical failures, unscheduled downtime, supplier disruptions, labor shortages, strikes, work stoppages or other labor difficulties, transportation interruptions, spills and releases and other environmental incidents) at any of our facilities, which would negatively impact our operating results;

•

changes in general economic, business, political and regulatory conditions in the countries or regions in which we operate could increase our costs, restrict our operations and reduce our operating results;

•

our ability to execute our organic growth plans may be negatively affected by our ability to complete projects on time and on budget;

•

the successful outcome of any strategic review of our assets, or our ability to acquire or dispose of product lines or businesses could disrupt our business and harm our financial condition;

•

uncertainties associated with worldwide economies could create reductions in demand and pricing, as well as increased counterparty risks, which could reduce liquidity or cause financial losses resulting from counterparty default;

•

the negative outcome of any legal, tax and environmental proceedings or changes in laws or regulations regarding legal, tax and environmental matters may increase our costs, reduce demand for our products, or otherwise limit our ability to achieve savings under current regulations;

•

any loss or non-renewal of favorable tax treatment under tax agreements or tax treaties, or changes in tax laws, regulations or treaties, may substantially increase our tax liabilities;

•

we may be required to reduce production or idle certain facilities because of the cyclical and volatile nature of the supply-demand balance in the chemical and refining industries, which would negatively affect our operating results;

1

•

we rely on continuing technological innovation, and an inability to protect our technology, or others’ technological developments, could negatively impact our competitive position;

•

we may be unable to continue operations until the shutdown of the Houston refinery within the expected timeframe or without incurring additional charges or expenses;

•

we have significant international operations, and fluctuations in exchange rates, valuations of currencies and our possible inability to access cash from operations in certain jurisdictions on a tax-efficient basis, if at all, could negatively affect our liquidity and our results of operations;

•

we are subject to the risks of doing business at a global level, including wars, terrorist activities, political and economic instability and disruptions and changes in governmental policies, which could cause increased expenses, decreased demand or prices for our products and/or disruptions in operations, all of which could reduce our operating results;

•

if we are unable to achieve our emission reduction, circularity, or other sustainability targets, it could result in reputational harm, changing investor sentiment regarding investment in our stock or a negative impact on our access to and cost of capital;

•

our ability to execute and achieve expected results of our value enhancement program;

•

if we are unable to comply with the terms of our credit facilities, indebtedness and other financing arrangements, those obligations could be accelerated, which we may not be able to repay; and

•

we may be unable to incur additional indebtedness or obtain financing on terms that we deem acceptable, including for refinancing of our current obligations; higher interest rates and costs of financing would increase our expenses.

Any of these factors, or a combination of these factors, could materially affect our future results of operations and the ultimate accuracy of the forward-looking statements. Our management cautions against putting undue reliance on forward-looking statements or projecting any future results based on such statements or present or prior earnings levels.

All subsequent written and oral forward-looking statements attributable to us or any person acting on our behalf are expressly qualified in their entirety by the cautionary statements contained or referred to in this section and any other cautionary statements that may accompany such forward-looking statements. Except as otherwise required by applicable law, we disclaim any duty to update any forward-looking statements, all of which are expressly qualified by the statements in this section, to reflect events or circumstances after the date of this prospectus.

DESCRIPTION OF CAPITAL STOCK

General

The following descriptions are summaries of material terms of LyondellBasell’s ordinary shares, with a par value of four eurocents (€0.04) each, LyondellBasell’s Articles of Association (which we refer to in this section as our Articles of Association) and Dutch law. The full text of our current Articles of Association has been filed with the SEC and is available, in Dutch and English, at our registered office in Rotterdam during regular business hours and is also available, in English, on our website.

Ordinary Shares

LyondellBasell’s authorized share capital is fifty-one million euro (€51,000,000), consisting of one billion two hundred seventy-five million (1,275,000,000) ordinary shares, each with a par value of four eurocents (€0.04). As of December 6, 2024, there were 324,410,304 ordinary shares outstanding, not including 16,012,194 ordinary shares held in treasury.

The description of LyondellBasell’s ordinary shares is contained in our Registration Statement on Form 10 filed with the SEC pursuant to Section 12 of the Exchange Act on April 28, 2010, as amended, which is incorporated by reference into this prospectus.

Voting and Approval Rights

Generally, each shareholder is entitled to one vote for each ordinary share held on every matter submitted to a vote of shareholders, including the annual election of members of the Board of Directors (the “Board”). There are no cumulative voting rights. Pursuant to Dutch law and our Articles of Association, the nomination of a director to our Board is binding on shareholders unless two-thirds of shareholders, representing at least half of issued share capital, vote against the nominee.

Unless otherwise required by our Articles of Association or Dutch law, matters submitted for a vote at a general meeting of shareholders require the approval of a majority of the votes cast at the general meeting. Pursuant to Dutch law and our Articles of Association, shareholders have the right to approve decisions of the Board regarding a significant change in the identity or nature of the Company, including decisions relating to (i) the transfer of all or substantially all our enterprise by way of a share or asset sale, consolidation or merger or otherwise, (ii) the entering into or termination of a long-lasting commercial relationship that is of essential importance to our business and (iii) the acquisition or disposition of shares or assets with a value of at least one-third of our consolidated asset value.

There are no laws currently in effect in The Netherlands or provisions in our Articles of Association limiting the rights of non-resident investors to hold or vote ordinary shares.

Dividends and Distributions

Pursuant to our Articles of Association, the Board may determine to allocate amounts to our reserves up to the amount of our annual profits. Out of our share premium reserve and other reserves available for shareholder distributions under Dutch law, the general meeting of shareholders may declare distributions upon a proposal of the Board. We cannot pay dividends if the payment would reduce our shareholders’

6

equity below the aggregate par value of our outstanding ordinary shares, plus reserves (if any) required to be maintained by law. The Board may, subject to certain statutory provisions, distribute one or more interim dividends or other interim distributions before the accounts for any year have been approved and adopted at a general meeting of shareholders, in anticipation of the final dividend or final distribution. Rights to dividends and distributions that have not been collected within five years after the date on which they first became due and payable revert to LyondellBasell.

The payment of dividends or distributions is subject to the requirements of Dutch law and the discretion of our shareholders (in the case of annual dividends) and our Board. The declaration of any cash dividends and, if declared, the amount of any such dividends, will depend upon general business conditions, our financial condition, our earnings and cash flow, our capital requirements, financial covenants and other contractual restrictions on the payment of dividends or distributions. There can be no assurance that any dividends or distributions will be declared or paid in the future. Any future cash dividends or distributions will be paid in U.S. dollars.

Shareholder Meetings

Each shareholder and certain other parties designated under Dutch law will be permitted, either personally or through an attorney authorized in writing, to attend the general meeting of shareholders, to address said meetings and to exercise voting rights, subject to certain provisions of Dutch law and our Articles of Association.

Our general meetings of shareholders will be held in The Netherlands at least annually, within six months after the close of each financial year. Extraordinary general meetings of shareholders may be held as often as the Board deems necessary, or as otherwise provided for pursuant to Dutch law. One or more shareholders representing in the aggregate at least 10% of the issued share capital can request the Board to convene a general meeting of shareholders. In such case, the Board is required to publish a convening notice for such a general meeting of shareholders within four weeks of receipt from such shareholders of (i) a specified agenda for such general meeting of shareholders and, (ii) in the sole discretion of the Board, compelling evidence of the number of shares held by such shareholder or shareholders. If such meeting is not held within six weeks of our receipt of such request, the shareholders requesting a meeting may petition a court in The Netherlands for an order directing the holding of such meeting; the court may order the holding of such a meeting if the persons requesting the meeting can demonstrate that they have a sufficient interest in holding a meeting with the agenda requested by them. In addition, affiliates of Access Industries, one of our shareholders, can require the Board to convene a general meeting of shareholders, for the purpose of allowing for the appointment of one or more of its director nominees under certain circumstances, for so long as it holds, together with its affiliates, at least 5% of the issued share capital.

One or more shareholders representing solely or jointly at least 1% of the issued share capital can request the Board to place a matter on the agenda, provided that the Board has received such request at least 60 days prior to the date of the general meeting of shareholders concerned and provided, further, that matters of strategy are the exclusive responsibility of the Board under Dutch law.

Election and Tenure of Directors

Our Board includes both executive and non-executive members. The executive members of our Board are charged with managing our day-to-day affairs. The non-executive members of our Board are charged with the supervision of the executive Board member(s) and our general course of affairs.

The Board shall determine its size; provided that the Board shall consist of at least nine members, including at least one executive Board member who will hold the title of CEO, and the number of non-executive Board members shall at all times exceed the number of executive Board members.

The general meeting of shareholders appoints the members of the Board, by vote on binding nominations prepared by the Board; provided that the Board may provide for temporary replacements in the event of a vacancy or the inability to act of a Board member.

We have entered into a nomination agreement with affiliates of Access Industries pursuant to which we agreed that (i) if it, together with its affiliates, owns 18% or more of our outstanding ordinary shares, it will

7

have the right to nominate three non-executive members of the Board; (ii) if it, together with its affiliates, owns at least 12% but less than 18% of our outstanding ordinary shares, it will have the right to nominate two non-executive members of the Board; and (iii) if it, together with its affiliates, owns at least 5% but less than 12% of our outstanding ordinary shares, it will have the right to nominate one non-executive member of the Board. The general meeting of shareholders may render such nomination non-binding by means of a resolution adopted by at least two-thirds of the valid votes cast, representing more than half of the issued capital. As of December 10, 2024, three of the members of our Board were nominated in accordance with this agreement.

The general meeting of shareholders may dismiss, or suspend for a period of up to three months, a member of the Board by a resolution adopted by at least two-thirds of the votes cast in a meeting where at least half of the issued share capital is represented. If the general meeting of shareholders has suspended a member of the Board, the general meeting of shareholders shall within three months after the suspension has taken effect resolve either to dismiss such relevant member, or to terminate or continue the suspension, failing which the suspension shall lapse.

Each member of the Board serves a one-year term and there is no limit to the number of times a member of the Board can be reappointed; however, our Corporate Governance Guidelines and Rules for the Board of Directors provide that a director shall not be renominated following their 75th birthday.

Subject to our Articles of Association, the Board may adopt rules and regulations governing its internal proceedings, including rules relating to voting on nominations of directors, board composition and governance.

Issuance of Ordinary Shares/Pre-emptive Rights

Our Articles of Association provide that our Board has the authority to issue shares if authorized by resolution of our shareholders. No such authorization is currently in place, except as relates to share issuances under certain shareholder-approved equity compensation plans. Shareholders may resolve to issue shares on a proposal of the Board in the absence of a Board authorization.

Under Dutch law and our Articles of Association, every holder of ordinary shares will have a preemptive right in the proportion that the aggregate amount of its ordinary shares bears to the total amount of shares outstanding. The preemptive right may be restricted or excluded by a resolution of the Board if the Board is the competent body to issue shares. Otherwise, preemptive rights may be restricted or excluded by shareholders on a proposal of the Board. A holder of ordinary shares will not have a preemptive right to shares which are being issued against contribution other than in cash; to ordinary shares which will be issued to our employees or employees of one of our group companies; and to ordinary shares which will be issued as a result of merger or demerger.

Repurchase of Ordinary Shares

The shareholders may delegate to the Board the authority, subject to certain restrictions contained in Dutch law and our Articles of Association, to cause us to acquire, for consideration, our own fully paid ordinary shares. Such authorization may not be granted for a period exceeding 18 months. In the authorization, the general meeting of shareholders shall determine how many shares thereof may be acquired, the manner in which they may be acquired and between what limits the price for such ordinary shares shall be.

The authorization will not be required for the acquisition of ordinary shares by us for transfer to our employees in accordance with an employee share plan.

At our 2024 general meeting of shareholders, shareholders granted authority to the Board to repurchase up to 10% of our issued share capital until November 24, 2025 on the open market, through privately negotiated repurchases, in self-tender offers, or through accelerated repurchase arrangements, at prices ranging from the nominal value of our shares up to 110% of the market price at the time of the transaction; provided that (i) for open market or privately negotiated repurchases, the market price shall be the price for our shares on the NYSE at the time of the transaction; (ii) for self-tender offers, the market price shall be the volume weighted average price (“VWAP”) for our shares on the NYSE during a period, determined by the

8

Board, of no less than one and no greater than five consecutive trading days immediately prior to the expiration of the tender offer; and (iii) for accelerated repurchase arrangements, the market price shall be the VWAP for our shares on the NYSE over the term of the arrangement. The VWAP for any number of trading days shall be calculated as the arithmetic average of the daily VWAP on those trading days.

Capital Reduction

Upon proposal by the Board, the general meeting of shareholders may reduce our issued share capital by cancellation of ordinary shares held by us, subject to certain statutory provisions. However, if less than one half of the issued share capital is present at the meeting, the general meeting of shareholders may only adopt a resolution for capital reduction with a majority of at least two-thirds of the votes cast. As of December 6, 2024, we held 16,012,194 million shares in our treasury account.

Amendment of Our Articles of Association

Our Articles of Association may be amended, on the proposal of the Board, by a majority of the votes cast at a general meeting of shareholders; provided that such proposal is stated in the notice for the general meeting and a complete copy of the proposed amendment is filed at our office so that it may be inspected prior to and during the meeting.

Transfer Agent

The transfer agent and registrar for our ordinary shares is Computershare Trust Company, N.A.

The debt securities of LyondellBasell, LYB International Finance, LYB International Finance II and LYB International Finance III covered by this prospectus will be the general unsecured obligations of LyondellBasell, LYB International Finance, LYB International Finance II and LYB International Finance III, respectively. The debt securities of LYB International Finance, LYB International Finance II and LYB International Finance III will be fully and unconditionally guaranteed by LyondellBasell. The debt securities of LyondellBasell may be fully and unconditionally guaranteed by LYB International Finance, LYB International Finance II or LYB International Finance III. LyondellBasell will issue senior debt securities under an indenture between LyondellBasell, as issuer, and Computershare Trust Company, N.A., as successor to Wells Fargo Bank, N.A., as trustee, dated as of March 5, 2015 (the “LyondellBasell Indenture”). LYB International Finance will issue senior debt securities fully and unconditionally guaranteed by LyondellBasell on a senior unsecured basis under an indenture among LYB International Finance, as issuer, LyondellBasell, as guarantor, and Computershare Trust Company, N.A., as successor to Wells Fargo Bank, N.A., as trustee, dated as of July 16, 2013 (the “LYB International Finance Indenture”).

The LyondellBasell Indenture, the LYB International Finance Indenture, the LYB International Finance II Indenture, and the LYB International Finance III Indenture are substantially identical except with regard to the entities that will issue and guarantee, if any, the debt securities governed by such indenture.

We have summarized certain material provisions of the indentures, the debt securities and the guarantees below. This summary is not complete. We have filed the indentures (or their forms) with the SEC as exhibits to the registration statement of which this prospectus forms a part, and you should read the indentures for provisions that may be important to you. Please read “Where You Can Find More Information.”

LyondellBasell, LYB International Finance, LYB International Finance II and LYB International Finance III may issue debt securities under the indentures from time to time in one or more series, each in an amount authorized prior to issuance.

LyondellBasell, LYB International Finance, LYB International Finance II and LYB International Finance III may sell the debt securities at a discount, which may be substantial, below their stated principal amount. These debt securities may bear no interest or interest at a rate that at the time of issuance is below market rates. If these debt securities are sold, we will describe in the prospectus supplement any material U.S. federal income tax consequences and other special considerations.

If any of the debt securities are sold for any foreign currency or currency unit or if payments on the debt securities are payable in any foreign currency or currency unit, we will describe in the prospectus supplement the restrictions, elections, tax consequences, specific terms and other information relating to those debt securities and the foreign currency or currency unit.

Limitation on Mergers and Consolidations.   The indentures generally permit a consolidation or merger involving LyondellBasell, LYB International Finance, LYB International Finance II or LYB International Finance III. They also permit LyondellBasell, LYB International Finance, LYB International Finance II or LYB International Finance III to sell, lease, convey, assign, transfer or otherwise dispose of all or substantially

11

all of their assets. Each of LyondellBasell, LYB International Finance, LYB International Finance II and LYB International Finance III has agreed, however, that it will not consolidate with or merge into any entity (other than, with respect to LYB International Finance, LYB International Finance II and LYB International Finance III, LyondellBasell), or sell, lease, convey, assign, transfer or otherwise dispose of, in any transaction or series of transactions, all or substantially all of its property and assets to any person (other than, with respect to LYB International Finance, LYB International Finance II and LYB International Finance III, LyondellBasell), unless:

•

either (i) it is the continuing entity or (ii) the resulting entity is organized under the laws of the United States, any state in the United States, the District of Columbia, Canada, any province of Canada or any state which was a member of the European Union on December 31, 2003 (other than Greece) and, in each case expressly assumes by a supplemental indenture the performance of its covenants and obligations under the applicable indenture and, in the case of LyondellBasell, LYB International Finance, LYB International Finance II or LYB International Finance III as the issuer, the due and punctual payment on the debt securities or, in the case of LyondellBasell with respect to the debt securities of LYB International Finance, LYB International Finance II or LYB International Finance III or LYB International Finance, LYB International Finance II or LYB International Finance III with respect to the debt securities of LyondellBasell, the performance of the related guarantee; and

•

immediately after giving effect to such transaction or series of transactions, no default or event of default occurred and is continuing or would result therefrom.

LyondellBasell is also permitted to sell, assign, transfer, lease, convey or otherwise dispose of, in one or more related transactions, assets constituting the capital stock or all or part of the assets of any subsidiary, division or line of business or group of such subsidiaries, divisions or lines of business (“disposed group”) if such disposed group (i) generated Consolidated EBITDA that was less than 40% of the Consolidated EBITDA of LyondellBasell in (a) the most recently completed four quarters or fiscal year for which financial statements are required to be delivered pursuant to the indenture and (b) each of the last three completed fiscal years of LyondellBasell for which financial statements are required to be delivered pursuant to the indenture and (ii) has total assets with a value that is less than 40% of the total value of the consolidated assets of LyondellBasell and its subsidiaries, as determined in accordance with GAAP as of the last date of the latest period for which financial statements are required to be delivered pursuant to the indenture; provided that such disposition otherwise complies with the indenture.

Upon any transaction of the type described in and effected in accordance with this covenant, the resulting entity will succeed to and be substituted for LyondellBasell, LYB International Finance, LYB International Finance II or LYB International Finance III, as applicable, and may exercise all of LyondellBasell’s, LYB International Finance’s, LYB International Finance II’s or LYB International Finance III’s rights and powers under the indentures and the debt securities with the same effect as if the resulting entity had been named as LyondellBasell, LYB International Finance, LYB International Finance II or LYB International Finance III, as applicable, in the indentures. In the case of any asset transfer or disposition other than a lease, when the resulting entity assumes all of LyondellBasell’s, LYB International Finance’s, LYB International Finance II’s or LYB International Finance III’s obligations and covenants under the applicable indenture and the debt securities, LyondellBasell, LYB International Finance, LYB International Finance II or LYB International Finance III, as applicable, will be relieved of all such obligations.

Events of Default.   Unless we inform you otherwise in the applicable prospectus supplement, the following are events of default with respect to a series of debt securities:

•

failure to pay interest or any additional amounts on any debt securities of that series for 30 days when due;

•

failure to pay principal of or any premium on any debt securities of that series when due;

•

failure to make or deposit any sinking fund payment for that series for 30 days when due;

•

failure to comply with any covenant or agreement in that series of debt securities or the applicable indenture (other than the events of default above or an agreement or covenant that has been included

12

in the applicable indenture solely for the benefit of other series of debt securities) for 90 days after written notice by the trustee or by the holders of at least 25% in principal amount of the outstanding debt securities issued under that indenture that are affected by that failure;

•

in the case of LYB International Finance, LYB International Finance II and LYB International Finance III debt securities, the related guarantee of LyondellBasell ceases to be in full force and effect with respect to the debt securities of such series (except as contemplated by the terms thereof) and such default continues for 10 days;

•

specified events involving bankruptcy, insolvency or reorganization of LyondellBasell and, with respect to LYB International Finance’s, LYB International Finance II’s or LYB International Finance III’s debt securities, LyondellBasell, or LYB International Finance, LYB International Finance II or LYB International Finance III, as applicable; and

•

any other event of default provided for that series of debt securities for 90 days after written notice by the trustee or by the holders of at least 25% in principal amount of the outstanding debt securities issued under the applicable indenture that are affected by that failure.

A default under one series of debt securities will not necessarily be a default under any other series. If a default or event of default for any series of debt securities occurs, is continuing and is known to the trustee, the trustee will notify the holders of the applicable series of debt securities within 90 days after it becomes known to the trustee. The trustee may withhold notice to the holders of the debt securities of any series of any default or event of default, except in any payment on the debt securities of such series, if the trustee in good faith determines that withholding notice is in the interests of the holders of those debt securities.

If an event of default for any series of debt securities occurs and is continuing, the trustee or the holders of at least 25% in principal amount of the outstanding debt securities of the series affected by the default (or, in the case of the event of default described in the fourth bullet above, 25% in principal amount of all debt securities issued under the applicable indenture that are affected by the default, voting as one class) may declare the principal of and all accrued and unpaid interest on those debt securities to be due and payable immediately. If an event of default relating to certain events of bankruptcy, insolvency or reorganization of us occurs, the principal of and accrued and unpaid interest on all the debt securities issued under that indenture will become immediately due and payable without any action on the part of the trustee or any holder. At any time after a declaration of acceleration has been made, the holders of a majority in principal amount of the outstanding debt securities of the series affected by the event of default (other than an event of default related to the non-payment of principal of or premium or interest on or any additional amounts) may in some cases rescind this accelerated payment requirement and its consequences.

A holder of a debt security of any series issued under an indenture may pursue any remedy under that indenture only if:

•

the holder gives the trustee written notice of a continuing event of default with respect to that series;

•

the holders of at least 25% in principal amount of the then outstanding debt securities of that series make a written request to the trustee to pursue the remedy;

•

the holders offer to the trustee indemnity satisfactory to the trustee against any loss, liability or expense;

•

the trustee does not comply with the request within 60 days after receipt of the request and offer of indemnity; and

•

during that 60-day period, the holders of a majority in principal amount of the debt securities of that series do not give the trustee a direction inconsistent with the request.

This provision does not, however, affect the right of a holder of a debt security to sue for enforcement of any overdue payment.

In most cases, the trustee will be under no obligation to exercise any of its rights or powers under an indenture at the request or direction of any of the holders of a series of debt securities unless those holders have offered to the trustee indemnity satisfactory to it. Subject to this provision for indemnification,

13

holders of a majority in principal amount of the outstanding debt securities of a series (or of all debt securities issued under an indenture that are affected, voting as one class) generally may direct the time, method and place of:

•

conducting any proceeding for any remedy available to the trustee; or

•

exercising any trust or power conferred on the trustee relating to or arising as a result of an event of default.

If an event of default occurs and is continuing, the trustee will be required to use the degree of care and skill of a prudent person in the conduct of his own affairs.

Each indenture requires LyondellBasell, LYB International Finance, LYB International Finance II and LYB International Finance III, as applicable, to file each year with the trustee a written statement as to their compliance with the covenants contained in the indenture.

Modification, Waiver and Meetings.   Each indenture may be amended or supplemented with the consent of the majority in principal amount of the outstanding debt securities of all series issued under that indenture that are affected by the amendment or supplement (voting as one class). Without the consent of the holder of each debt security affected, however, no modification may:

•

reduce the amount of debt securities of the relevant series whose holders must consent to an amendment, supplement or waiver;

•

reduce the rate of or change the time for payment of interest on the debt securities;

•

reduce the principal of, any premium on or any mandatory sinking fund payment with respect to the debt securities or change their stated maturity;

•

reduce any premium payable on the redemption of the debt security or change the time at which the debt securities may or must be redeemed;

•

change any obligation to pay additional amounts on the debt securities;

•

make payments on the debt securities payable in currency other than as originally stated in the debt securities;

•

impair the holder’s right to institute suit for the enforcement of any payment on or with respect to the debt securities;

•

make any change in the percentage of principal amount of debt securities of the relevant series for a waiver of default or make any change in the provisions related to the rights of holders to receive payment or in these bullets regarding modification without the consent of holders;

•

waive a continuing default or event of default regarding any non-payment of principal of or premium or interest on or any additional amounts with respect to the debt securities; or

•

if applicable, make any change that materially and adversely affects the right to convert any debt security pursuant to its terms.

Each indenture may be supplemented or amended or any provision of that indenture may be waived without the consent of any holders of debt securities issued under that indenture in certain circumstances, including:

•

to cure any ambiguity, omission, defect or inconsistency;

•

to provide for the assumption of LyondellBasell’s, LYB International Finance’s, LYB International Finance II’s or LYB International Finance III’s obligations, as applicable, under the applicable indenture by a successor upon any merger, consolidation or asset transfer permitted under that indenture;

•

to provide for uncertificated debt securities in addition to or in place of certificated debt securities;

•

to provide any security for, or to add any guarantees of or obligors on, any series of debt securities or the related guarantees;

14

•

to conform to this description of debt securities or the description of the notes included in the prospectus supplement with respect to the debt securities of a particular series of debt securities;

•

to comply with any requirement to effect or maintain the qualification of an indenture under the Trust Indenture Act of 1939 (the “Trust Indenture Act”);

•

to add covenants that would benefit the holders of any debt securities or to surrender any rights we have under an indenture;

•

to add events of default with respect to any series of debt securities;

•

to make any change that does not adversely affect any outstanding debt securities of any series issued under an indenture in any material respect;

•

to amend or supplement an indenture to permit or facilitate the defeasance and discharge of any series of debt securities pursuant to the applicable provisions of such indenture; and

•

to establish the form or terms of any debt securities and to accept the appointment of a successor trustee, each as permitted under the applicable indenture.

The holders of a majority in principal amount of the outstanding debt securities of any series (or, in some cases, of all debt securities issued under the indenture that are affected, voting as one class) may waive any existing or past default or event of default with respect to those debt securities. Those holders may not, however, waive any:

•

default or event of default in any payment on any debt securities; or

•

compliance with a provision that cannot be amended or supplemented without the consent of each holder affected.

We, the trustee or the holders of at least 331∕3% in principal amount of the outstanding debt securities of the applicable series, may at any time call a meeting of the holders of debt securities of a particular series for the following purposes:

•

to give any notice to us or the trustee, or to give any directions to the trustee, or waive any default or event of default and its consequences or to take any other action authorized to be taken by the holders pursuant to the applicable indenture;

•

to remove the trustee and nominate a successor trustee;

•

to consent to the execution of an indenture or of indentures supplemental to an indenture; or

•

to take any other action authorized to be taken by or on behalf of the holders of any specified aggregate principal amount of the debt securities of any one or more or all series, as the case may be, under any other provision of the applicable indenture or under applicable law.

Any resolution passed or decision taken at any meeting of holders of debt securities of a particular series duly held in accordance with the applicable indenture will be binding on all holders of debt securities of that series. The quorum at any meeting called for the holders of debt securities of a particular series to adopt a resolution will be the presence of persons holding or representing such debt securities of that series in an aggregate principal amount sufficient to take action upon the business for the transaction of which the meeting was called.

Defeasance.   When we use the term defeasance, we mean discharge from some or all of our obligations under the applicable indenture. If we deposit with the trustee under the indenture any combination of funds or government securities sufficient to make payments on the debt securities of a series issued under that indenture on the dates those payments are due and payable, then, at the option of LyondellBasell, LYB International Finance, LYB International Finance II or LYB International Finance III, as applicable, either of the following will occur:

•

LyondellBasell and, with respect to the LYB International Finance, LYB International Finance II and LYB International Finance III indentures, LyondellBasell and LYB International Finance, LYB International Finance II or LYB International Finance III, as applicable, will be discharged from its or their obligations with respect to the debt securities of that series (“legal defeasance”); or

15

•

LyondellBasell and, with respect to the LYB International Finance, LYB International Finance II and LYB International Finance III indentures, LyondellBasell and LYB International Finance, LYB International Finance II or LYB International Finance III, as applicable, will no longer have any obligation to comply with the restrictive covenants applicable to that series of debt securities, and the related events of default will no longer apply (“covenant defeasance”).

If a series of debt securities is defeased, the holders of the debt securities of the series affected will not be entitled to the benefits of the applicable indenture, except for obligations to register the transfer or exchange of debt securities, replace stolen, lost or mutilated debt securities, maintain paying agencies and hold moneys for payment in trust. In the case of covenant defeasance, the obligation of LyondellBasell, LYB International Finance, LYB International Finance II or LYB International Finance III to pay principal, premium, interest and any additional amounts on the debt securities will also survive.

Unless we inform you otherwise in the prospectus supplement, we will be required to deliver to the trustee an opinion of counsel that the deposit and related defeasance would not cause the beneficial owners of the debt securities to recognize income, gain or loss for U.S. federal income tax purposes. If we elect legal defeasance, that opinion of counsel must be based upon a ruling from the U.S. Internal Revenue Service or a change in law to that effect.

Satisfaction and Discharge.   In addition, an indenture will cease to be of further effect with respect to the debt securities of a series issued under that indenture, subject to exceptions relating to compensation and indemnity of the trustee and repayment to us of excess money or government securities, when:

•

either

•

all outstanding debt securities of that series have been delivered to the trustee for cancellation; or

•

all outstanding debt securities of that series not delivered to the trustee for cancellation either:

•

have become due and payable,

•

will become due and payable at their stated maturity within one year, or

•

are to be called for redemption within one year; and

•

any combination of money or government securities in trust sufficient to pay the entire indebtedness on the debt securities of that series when due has been deposited with the trustee; and

•

all other sums payable by LyondellBasell, LYB International Finance, LYB International Finance II or LYB International Finance III with respect to the debt securities of that series have been paid.

Governing Law.   New York law will govern the indentures, the debt securities and the guarantees.

Trustee.   Deutsche Bank Trust Company Americas is the trustee under the LYB International Finance II Indenture. Certain of Deutsche Bank Trust Company Americas’ affiliates perform certain commercial banking services for us for which they receive customary fees. Computershare Trust Company, N.A. is the trustee under the LyondellBasell Indenture and LYB International Finance Indenture and base trustee under the and LYB International Finance III Indenture. The Bank of New York Mellon Trust Company, N.A. is the trustee under the LYB International Finance III Indenture. Certain of The Bank of New York Mellon Trust Company, N.A.’s affiliates perform certain commercial banking services for us for which they receive customary fees.

Each indenture contains limitations on the right of the trustee, if it or any of its affiliates becomes our creditor, to obtain payment of claims or to realize on certain property received for any such claim, as security or otherwise. The trustee and its affiliates are permitted to engage in other transactions with us. If, however, the trustee acquires any conflicting interest within the meaning of the Trust Indenture Act, it must eliminate that conflict or resign.

Form, Exchange, Registration and Transfer.   The debt securities will be issued in registered form, without interest coupons. There will be no service charge for any registration of transfer or exchange of the debt securities. However, payment of any transfer tax or similar governmental charge payable for that registration may be required.

16

Debt securities of any series will be exchangeable for other debt securities of the same series, the same total principal amount and the same terms but in different authorized denominations in accordance with the applicable indenture. Holders may present debt securities for registration of transfer at the office of the security registrar or any transfer agent we designate. The security registrar or transfer agent will affect the transfer or exchange if its requirements and the requirements of the applicable indenture are met.

The trustee will be appointed as security registrar for the debt securities. If a prospectus supplement refers to any transfer agents LyondellBasell, LYB International Finance, LYB International Finance II or LYB International Finance III, as applicable, initially designates, LyondellBasell, LYB International Finance, LYB International Finance II or LYB International Finance III, as applicable, may at any time rescind that designation or approve a change in the location through which any transfer agent acts. We are required to maintain an office or agency for transfers and exchanges in each place of payment. LyondellBasell, LYB International Finance, LYB International Finance II or LYB International Finance III, as applicable, may at any time designate additional transfer agents for any series of debt securities.

In the case of any redemption, LyondellBasell, LYB International Finance, LYB International Finance II or LYB International Finance III, as applicable, will not be required to register the transfer or exchange of:

•

any debt security during a period beginning 15 business days prior to the mailing of the relevant notice of redemption or repurchase and ending on the close of business on the day of mailing of such notice; or

•

any debt security that has been called for redemption in whole or in part, except the unredeemed portion of any debt security being redeemed in part.

Payment and Paying Agents.   Unless we inform you otherwise in a prospectus supplement, payments on the debt securities will be made in U.S. dollars at the office of the trustee and any paying agent. At LyondellBasell’s, LYB International Finance’s, LYB International Finance II’s or LYB International Finance III’s option, as applicable, however, payments may be made by wire transfer for global debt securities or by check mailed to the address of the person entitled to the payment as it appears in the security register. Unless we inform you otherwise in a prospectus supplement, interest payments may be made to the person in whose name the debt security is registered at the close of business on the record date for the interest payment.

Unless we inform you otherwise in a prospectus supplement, the trustee under the applicable indenture will be designated as the paying agent for payments on debt securities issued under that indenture. LyondellBasell, LYB International Finance, LYB International Finance II or LYB International Finance III, as applicable, may at any time designate additional paying agents or rescind the designation of any paying agent or approve a change in the office through which any paying agent acts.

If the principal of or any premium or interest on debt securities of a series is payable on a day that is not a business day, the payment will be made on the following business day. For these purposes, unless we inform you otherwise in a prospectus supplement, a “business day” is, when used with respect to any place of payment or any other particular location referred to in the indenture or in the debt securities of any series, any day except a Saturday, Sunday or any other day on which commercial banks in such place of payment or other location are authorized or obligated by law or executive order to close.

Subject to the requirements of any applicable abandoned property laws, the trustee and paying agent will pay to LyondellBasell, LYB International Finance, LYB International Finance II or LYB International Finance III, as applicable, upon written request any money held by them for payments on the debt securities that remains unclaimed for two years after the date upon which that payment has become due. After payment to LyondellBasell, LYB International Finance, LYB International Finance II or LYB International Finance III, holders entitled to the money must look to LyondellBasell, LYB International Finance, LYB International Finance II or LYB International Finance III, as the case may be, for payment. In that case, all liability of the trustee or paying agent with respect to that money will cease.

Book-Entry Debt Securities.   The debt securities of a series may be issued in the form of one or more global debt securities that would be deposited with a depositary or its nominee identified in the prospectus supplement. Global debt securities may be issued in either temporary or permanent form. We will describe in

17

the prospectus supplement the terms of any depositary arrangement and the rights and limitations of owners of beneficial interests in any global debt security.

Ranking.   The debt securities will constitute senior debt of LyondellBasell, LYB International Finance, LYB International Finance II or LYB International Finance III, as applicable, and will rank equally with all of the other series of debt securities issued under the applicable indenture and will rank senior to all series of subordinated securities issued by them and outstanding from time to time.

Restrictive Covenants.   Each of the indentures contains restrictions on the activities of LyondellBasell and its subsidiaries for the benefit of holders of the debt securities. The restrictive covenants summarized below will apply to a series of debt securities (unless waived or amended) as long as any of those debt securities are outstanding, unless the prospectus supplement for the series states otherwise. We have used in this summary description of the restrictive covenants the capitalized terms that we have defined below under “Glossary.”

Limitation on Liens

Each indenture provides that LyondellBasell will not, nor will it permit any subsidiary to, create, incur, issue, assume or guarantee any Debt secured by a Lien of or upon any Principal Property or Capital Stock of any subsidiary that directly owns any Principal Property, whether such Principal Property or Capital Stock is owned as of the date of issuance of the applicable debt securities or thereafter acquired, without in any such case making or causing to be made effective provision (and LyondellBasell covenants that in any such case it shall make or cause to be made effective provision) whereby the debt securities (together with, if LyondellBasell shall so determine, any other Debt created, incurred, issued, assumed or guaranteed by LyondellBasell or any subsidiary then existing or thereafter created) shall be secured by such Lien equally and ratably with (or, at the option of LyondellBasell, prior to) such Debt, so long as such Debt shall be so secured. The foregoing restrictions will not, however, apply to Debt secured by Permitted Liens.

In addition, LyondellBasell or any subsidiary may, without equally and ratably securing the debt securities, issue, assume or guarantee Debt that would otherwise be subject to the foregoing restrictions, if at the time of such issuance, assumption or guarantee, after giving effect thereto and to the retirement of any Debt which is concurrently being retired, the aggregate amount of all such Debt secured by Liens which would otherwise be subject to such restriction (other than any Debt secured by Liens permitted as described under clauses (1) through (7) of the definition of Permitted Liens) plus the aggregate amount of all Attributable Debt of LyondellBasell and any of its subsidiaries in respect of Sale and Lease-Back Transactions (with the exception of such transactions which are permitted pursuant to clauses (1) and (2) of the first sentence of the first paragraph under “— Limitation on Sale / Lease-Back Transactions”, below) does not exceed 15% of Consolidated Net Tangible Assets of LyondellBasell.

Limitation on Sale / Lease-Back Transactions

LyondellBasell will not, and will not permit any of its subsidiaries to, enter into any Sale and Lease-Back Transaction with respect to any Principal Property unless,

(1)   LyondellBasell or such subsidiary would (at the time of entering into such arrangement) be entitled pursuant to clause (1) or (6) of the definition of Permitted Liens, without equally and ratably securing the debt securities, to create, issue, assume or guarantee Debt secured by a Lien on such Principal Property; or

(2)   LyondellBasell or such subsidiary shall apply, within 180 days of the effective date of any such arrangement, an amount not less than the greater of (x) the net proceeds of the sale of such Principal Property or (y) the fair market value (as determined by the Board of Directors of LyondellBasell) of such Principal Property to either the prepayment or retirement (other than any mandatory prepayment or retirement) of Debt incurred or assumed by LyondellBasell or any subsidiary (other than indebtedness owned by LyondellBasell or any subsidiary) which by its terms matures at or is extendible or renewable at the option of the obligor to a date more than twelve months after the date of the creation of such Debt, or to the acquisition, construction or improvement of a manufacturing plant or manufacturing facility; or

18

(3)   the Attributable Debt of LyondellBasell and its subsidiary in respect of such Sale and Lease-Back Transaction and all other Sale and Lease-Back Transactions entered into after the Issue Date (other than any such Sale and Lease-Back Transaction as would be permitted as described in clauses (1) and (2) of this covenant), plus the aggregate principal amount of Debt secured by Liens then outstanding (not including any such Debt secured by Liens described in clauses (1) through (7) of the definition of Permitted Liens) which do not equally and ratably secure the debt securities (or secure debt securities on a basis that is prior to other Debt secured thereby) would not exceed 15% of Consolidated Net Tangible Assets of LyondellBasell.

Glossary

“Attributable Debt” in respect of a Sale and Lease-Back Transaction means, as of any particular time, the present value (discounted at the rate of interest implicit in the terms of the lease involved in such Sale and Lease-Back Transaction, as determined in good faith by LyondellBasell) of the obligation of the lessee thereunder for rental payments (excluding, however, any amounts required to be paid by such lessee, whether or not designated as rent or additional rent, on account of maintenance and repairs, insurance, taxes, assessments, water rates or similar charges or any amounts required to be paid by such lessee thereunder contingent upon the amount of sales, maintenance and repairs, insurance, taxes, assessments, water rates or similar charges) during the remaining term of such lease (including any period for which such lease has been extended or may, at the option of the lessor, be extended).

DESCRIPTION OF GUARANTEES

Guarantee of LYB International Finance, LYB International Finance II and LYB International Finance III Debt Securities

LyondellBasell will fully and unconditionally guarantee on a senior unsecured basis the full and prompt payment of the principal of, any premium and interest on, and any additional amounts which may be payable by LYB International Finance, LYB International Finance II and LYB International Finance III in respect of the debt securities issued by LYB International Finance, LYB International Finance II and LYB International Finance III, as applicable, when and as the payment becomes due and payable, whether at maturity or otherwise. The guarantees provide that in the event of a default in the payment of principal of, any premium and interest on, and any additional amounts which may be payable by LYB International Finance, LYB International Finance II or LYB International Finance III, as applicable, in respect of such debt securities, the holder of the debt securities may institute legal proceedings directly against LyondellBasell to enforce the guarantees without first proceeding against LYB International Finance, LYB International Finance II or LYB International Finance III, as applicable. The guarantees will rank equally with all of LyondellBasell’s other unsecured and unsubordinated debt from time to time outstanding.

Guarantee of LyondellBasell Debt Securities

LYB International Finance, LYB International Finance II and LYB International Finance III may fully and unconditionally guarantee LyondellBasell’s payment obligations under any series of debt securities issued by LyondellBasell. If a series of debt securities is so guaranteed, LYB International Finance, LYB International Finance II and LYB International Finance III, as applicable, will execute a separate guarantee agreement or a supplemental indenture as evidence of its guarantee. We will provide the specific terms of any such guarantee in the applicable prospectus supplement.

(1)

Estimated expenses are not presently known. The foregoing sets forth the general categories of expenses that we anticipate we will incur in connection with the offering of securities under this registration statement on Form S-3. An estimate of the aggregate expenses in connection with the issuance and distribution of the ordinary shares being offered hereby will be included in the applicable prospectus supplement.

ITEM 15.   INDEMNIFICATION OF DIRECTORS AND OFFICERS

Indemnification Arrangements

Article 24 of Chapter XI of the Articles of Association of LyondellBasell contains indemnification provisions for its current and former directors and officers, as well as directors and officers of its subsidiaries, including LYB International Finance, LYB International Finance II and LYB International Finance III, as described generally below.

Pursuant to the Articles of Association, we are obligated to indemnify and hold harmless, to the fullest extent permitted by applicable law, any person who was or is made or is threatened to be made a party or is otherwise involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative by reason of the fact that he or she (or a person or entity for whom he or she) is or was a member of the LyondellBasell Board or a similar body of its subsidiaries or is or was serving as an agent of LyondellBasell, including service with respect to employee benefit plans. For these purposes, an “agent” includes any person who is or was a Board member, officer, employee or other agent of LyondellBasell or is or was serving at our request as a board member, director, officer, employee or other agent of another company, partnership, joint venture, trust or other enterprise. Our indemnification obligation applies to all liability and loss suffered and expenses (including attorneys’ fees) reasonably incurred, except that our indemnification does not apply in respect of any claim, issue or matter as to which the person is adjudged to be liable for gross negligence or willful misconduct in the performance of his or her duty to us, unless and only to the extent that the court in which such action suit or proceeding was brought or any other court having appropriate jurisdiction determines otherwise.

II-1

Expenses (including attorneys’ fees) incurred in defending a proceeding may be paid by us in advance of the final disposition of such proceeding upon a resolution of our Board with respect to the specific case upon receipt of an undertaking by or on behalf of the person seeking to have his or her expenses paid to repay such amount unless it shall ultimately be determined that he or she is entitled to be indemnified by us.

We have entered into indemnification agreements with our current directors. We believe that these indemnification agreements are necessary to attract and retain qualified persons as our directors. The SEC has noted, however, that in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable.

Any underwriting agreement or distribution agreement that we enter into with any underwriters or agents involved in the offering or sale of any securities registered hereby may require such underwriters or dealers to indemnify us, some or all of our directors and officers and our controlling persons, if any, for specified liabilities, which may include liabilities under the Securities Act.

We maintain directors’ and officers’ liability insurance coverage.

ITEM 17.   UNDERTAKINGS

Each of the undersigned registrants hereby undertakes:

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

(i)   To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(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

II-5

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 Commission 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;

(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 (i), (ii) and (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 Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 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.

(2)   That, for the purpose of determining any liability under the Securities Act of 1933, 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.

(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.

(4)   That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

(A)   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

(B)   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 of 1933 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.

(5)   That, for the purpose of determining liability of the Registrant under the Securities Act of 1933 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:

II-6

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

(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;

(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

(iv)   Any other communication that is an offer in the offering made by the undersigned Registrant to the purchaser.

(6)   That, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) 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.

(7)   To file an application for the purpose of determining the eligibility of the trustee under each indenture identified in Exhibits 25.1, 25.2 and 25.3 hereto to act under subsection (a) of Section 310 of the Trust Indenture Act in accordance with the rules and regulations prescribed by the Commission under Section 305(b)(2) of the Trust Indenture Act.

(8)   Insofar as indemnification for liabilities arising under the Securities Act of 1933 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 and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 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 of 1933 and will be governed by the final adjudication of such issue.
